Answer : I m using Windows Server 2012 64bit and am investigating using iFilters as a means of extracting and indexing data from various file types . One of the file types is .msg MS email . The iFilter is mostly doing its job and retrieving the text as requested but it fails to retrieve the email content . I can t find anyone complaining of the same problem so suspect I am doing something wrong but cannot work out what it is especially when all the other filetypes work correctly . I ve tried adding the Windows Search feature and reviewed the Indexing Options to ensure .msg iFilters are set to retrieve properties and content . All fine there and I doubt that would cause it anyway as I m not using the Windows Search feature . I ve used the iFilters that come as default in with an Office 2013 installation and have also tried the iFilters that come with the Microsoft Office 2010 Filter Pack up to service pack 2 .

The code you are referring to is old but still valid . However there are now more interfaces in use beside GetTextFromFile . You will need to use the stream reader read up in IPersistStream in the link I mentioned above .

Good luck Marco Comment : This seems to be the right track but I haven t been able to find any working examples nor get anything working myself . I also read that the Adobe PDF IFilter works only with files and not with a stream - not sure if this is true - but am wondering if this is actually going to be possible . Comment : Wasn t there a 2005 sample code on codeplex Anyhow the lack of live samples was a great frustration for me in my project . Look at the Microsoft definition for the stream interface and go from there . There is a buffer memory and a flag that signalls you need to repeat the call to get another fill for the buffer . For PDF ifilter you may need to look at a different supplier as previously adobe has not been the first to supply e.g . the 64 bit version .

I am trying to develop an IFilter for a proprietary file-format . The IPersistStream interface is implemented in the filter although there is no tool to test this interface.. . . The DLL goes through all the tests in the IFilter test suite ifilttst filtdump filtreg ifilttst emitted property values are correct it is installed in c : windows system32 but it is not properly run by SearchFilterHost.exe used by Windows indexing services . Nothing is indexed . I used Process Monitor procmon.exe to look at when SearchFilterHost is using the IFilter . During re-indexing of the disk or when a file name handled by the IFilter is changed SearchFilterHost loads the image of the IFilter but then nothing else happens . Dependency Walker found DLLs that were missing some are found in the c : windows system32 IEHIMS.DLL API-MS-WIN-CORExxx.DLL etc.. . but I doubt I could be wrong it would make much of a difference because the ifilttst is running fine . I am at my wit s end . Could someone help Thanks Comment : is your filter 32-bit or 64 bit What about your OS Comment : Your best bet is to add logging to each of your method and also to QueryInterface so that you know which interfaces are being requested and whether you can supply those and which methods are invoked with what parameters and whether your code handles this properly .

Files such as .odt files cannot be indexed on Windows Search . The error says Registered IFilter is not found .. . .. . Any help please .. . Answer : IFilters are used to convert file formats into text for searching . The trouble is that they need to be the same bitness as the app that wants to load them . So if you have a 64-bit app that wants to use the IFilters you need 64-bit IFilters installed .

Use IFilter Explorer to know which IFilter is STA : http : www.citeknet.com Products IFilters IFilterExplorer tabid 62 Default.aspx .. . .. . The solution you can use if you wanna keep your app multithreaded for other filters is to spin a thread that you dedicate to STA IFilters and keep it around for the lifetime of the application .

Answer : Stelio .. . .. . There are a lot of people with this issue with Adobe s iFilter . The thought is it comes down the permissions required to run the iFilter . Sitecore support s official answer on this can be found in this similar SO answer - Sitecore 7 pdf indexing http : stackoverflow.com questions 17998725 sitecore-7-pdf-indexing .. . .. . However I still had issues with Adobe s iFilter after following these steps as well as steps outlined in this blog post - http : www.sitecore.net Learn Blogs Technical-Blogs Sitecore-7-Development-Team Posts 2013 06 Why-does-my-IFilter-not-work.aspx .. . .. . After troubleshooting for quite a while on this I did finally find a combination that worked but then we started having the Adobe iFilter crash on a number of PDF files . Knowing newer versions of Adobe s iFilter have even more challenges we just opted to purchase FoxIt s PDF IFilter http : www.foxitsoftware.com products ifilter which is faster and much more reliable . Have not had any issues with it up to this point . The cost can be somewhat significant if you are using Lucene and are relying on your Content Delivery servers to build their caches since you will need a license for each server . If you are using SOLR or a dedicated crawling server you should only need licenses for the server building the indexes . Comment : Matt thanks for answering most of the links point to the version 9 of the Ifilter and it says that it does not work on the following versions and I was not able to find on line Ifilter 9.. . So I guess that the only choice is to go with a custom Ifilter for Pdf indexing or build your custom one not a great option neither.. . Comment : Stelio wish I had a better answer for you .

It s 64bit v9 : download.adobe.com pub adobe acrobat win 9.x http : download.adobe.com pub adobe acrobat win 9.x PDFiFilter64installer.zip", "Question : For a C web application I am wanting to index text from PDF DOC etc files stored in a database . I have been experimenting with an IFilter example on Code Project http : www.codeproject.com KB cs IFilter.aspx which works great for files from the file system but my files are stored in a MS-SQL database . Can anyone help me locate a sample to extract text from files stored in a database or have an idea on how to modify the Code Project code to work with a database instead of the file system .. . Answer : Finally after many hours I figured out how to make this work I needed to run IFilter on PDF content stored in a database and I wanted to avoid saving the data to temporary files . First I tried to use the BindIFilterFromStream http : msdn.microsoft.com en-us library ms690827 28v vs.85 29.aspx API to create an IFilter for content stored in a Stream but it seems that it doesn t work properly at least not for this scenario . So don t go that way . Instead you need to create an IFilter for a file extension or access it some other way . Then you can access the IPersistStream http : msdn.microsoft.com en-us library windows desktop ms690091 28v vs.85 29.aspx COM interface and use it to load the PDF content into the IFilter . The rest works the same as for files . However note that the IPersistStream API may not be implemented by every IFilter . It works for the Adobe PDF IFilter though . The code should look like this I removed some return code checking to make the code more readable however you should check all possible return codes . Text extraction from the filter looks like this in my code . There are many examples of this on the web and it can be implemented in many ways depending on what you need . And here are the definitions of native methods and the structures used by them . Comment : Wow that s what I call a detailed answer", "Question : I m using IPersistFile in C to load a file before reading it as an IFilter : .. . .. . This works fine . However I would like to load the file contents from memory instead of a disk path . Is that possible The IPersistFile interface does not show any other way than providing a path string so it seems neither a memory mapped file nor a byte array can be used . .. . Answer : As a preleminary answer sketch : My research indicates http : msdn.microsoft.com en-us library aa965717 28v vs.85 29.aspx that it might be possible to cast to IPersistStream http : msdn.microsoft.com en-us library ms690091 28v vs.85 29.aspx instead of IPersistFile which allows loading from an IStream and thus from a memory target . Comment : Yes all sane IFilter implementation should implement IPersistStream and you can just try to query IPersistStream and use it . Comment : @sharptooth Thanks I see . So an IFilter should implement as many IPersistX interfaces as possible to be usable in all situations . Comment : Well not really the minimum seems to be IFilter IPersistFile and IPersistStream . Comment : Be aware some iFilters ONLY support one of the IPersist interfaces . Windows Search uses the IPersistStream interface on iFilters but does not use IPersistFile . And ifilttst uses IPersistFile . Some manufacturers only implement one to limit their usability on purpose .", "Question : I ve implemented an IFilter as a native VC++ ATL in-proc COM server .

I say that your answer is redundant as it says the same things somewhat condensed I say in my answer . But whatever I shouldn t care .", "Question : I was looking into the C11 draft and it says .. . .. . An unnamed member of structure type with no tag is called an anonymous structure an unnamed member of union type with no tag is called an anonymous union . The members of an anonymous structure or union are considered to be members of the containing structure or union . So I constructed the following testcase .. . .. . Clang and GCC both complain about the unnamed member saying that the declaration has both effect . Did I do something wrong or do they simply not support that feature yet Comment : I don t think this is what an anonymous-struct is . Note the word tag . That s the type tag of the struct or union as in struct foo .. . f - here foo is the tag . Comment : @user3477950 yes AToW has no tag . .. . Answer : No that s not an unnamed member . An example is : .. . .. . The inner structure containing members b and c is an unnamed member of struct outer . The members of this unnamed member b and c are considered to be members of the containing structure . This is probably more useful with a contained union rather than a contained structure . In particular it can be used to define something similar to a Pascal or Ada variant record : .. . .. . This lets you refer to i d and p directly as members of a struct variant object rather than creating an artificial name for the variant portion . If some variants require more than one member you can nest anonymous structures within the anonymous union . It differs from Pascal and Ada in that there s no mechanism to enforce which variant is active given the value of the type member that s C for you .

You re not permitted to have a bare .. . .. . in the middle of a struct definition any more than you can have a bare .. . .. . C11 added the ability to define a nested anonymous-struct within another struct but only by defining a new anonymous-struct type at that point . You can t have an anonymous-struct member of a previously defined type . The language could have been defined to permit it and the semantics would I think be reasonably straightforward -- but there wasn t much point in defining two different ways to do the same thing . For struct in the above read struct or union .

An unnamed member whose type specifier is a structure specifier with no tag is called an anonymous structure an unnamed member whose type specifier is a union specifier with no tag is called an anonymous union . The members of an anonymous structure or union are considered to be members of the containing structure or union . This applies recursively if the containing structure or union is also anonymous . A structure specifier consists of the keyword struct followed by an optional identifier the tag omitted in this case followed by a sequence of declarations enclosed in and . In your case AToW is a type name not a structure specifier so it can t be used to define an anonymous structure . Comment : I don t see the difference of that to my case apart from the fact that you use a struct specifier as the type and I used an ordinary identifier as the type . Why is my AToW not an unnamed member If I would change it to AToW x it would become a named member . Comment : @JohannesSchaub-litb : See the updated last paragraph of my answer . TL DR : Because the standard says so . Comment : You re not permitted to have a bare AToW in the middle of a struct definition any more than you can have a bare int - does the quote I gave not permit it It says An unnamed member of structure type with no tag is called an anonymous structure an unnamed member of union type with no tag is called an anonymous union and goes on to define its semantics . So the question comes down to Why is AToW not an anonymous-struct and I don t see it yet . int is not because int is not a struct type that s easy .

Consider the anonymous-struct used in the cast inside the print function and the anonymous-struct that is the first member of the struct container that winds up in main.c . Could they be considered types declared in separate translation units Also do they really satisfy all the other compatibility requirements or am I misunderstanding something Comment : As a note identical structures always have the same memory layout at least for an implementation where separate source files can be compiled and linked independently even if they are incompatible because of the possibility that there is another identical structure compatible with both of them in another translation-unit . The question here is if strict aliasing is violated . Comment : @mafso : of course I am well aware of that . I am simply interested if the behaviour in this case is well-defined by the standard . Comment : As another note this isn t really about anonymous structs but about structures without a tag . So the question also applies to C99 . Comment : I referred to .. . not well-defined as they are not compatible and therefore not guaranteed to have the same memory layout . An implementation where they don t would be quite contrived . Strict-aliasing on the other hand may become an issue with real code on a real implementation . And I m also curious about the question I didn t question it . .. . Answer : What is a translation-unit : .. . .. . 5.1.1.1 Program Structure .. . .. . 1 . A C program need not all be translated at the same time . The text of the program is kept in units called source files or preprocessing files in this International Standard . A source file together with all the headers and source files included via the preprocessing directive include is known as a preprocessing translation-unit . After preprocessing a preprocessing translation-unit is called a translation-unit . .. . .. . So the c file plus the headers after preprocessing form a single translation-unit . Let s take the translation-unit which is made out of sep.c and header.h . It contains two declarations of the struct struct int a char b one in the struct container and the other in the function print . Those structs are declared in the same translation-unit . 6.2.7 Compatible type and composite type .. . .. . 1 . Two types have compatible type if their types are the same . Additional rules for determining whether two types are compatible are described in 6.7.2 for type specifiers in 6.7.3 for type qualifiers and in 6.7.6 for declarators . Moreover two structure union or enumerated-types declared in separate translation.. . .. . .. . the remaining text is referring to types declared in separate translation units . Since the structs are not declared in separate translation units they do not fall under the 6.2.7 rule . Therefore in my interpretation the structs the one in struct container and the other in the cast in the print aren t compatible . Comment : Yes but the question was about the struct container that winds up in main.c . Technically if I understand correctly it s supposed to be the real type of the object pointed to by the pointer passed to the print function . Of course it is compatible with the struct container declared in sep.c but wouldn t this make it a separate concern Comment : @Mints97 Where the pointer comes from doesn t matter . Calling the function from main doesn t change the fact that the structs are not compatible in the other translation-unit . Comment : @Mints97 No type struct container in main is compatible with the one in sep and that is what you pass . But the anonymous structs aren t . This is my interpretation . Interesting question though . Comment : thanks for your input let s wait for someone else s interpretation of the standard . You didn t convince me P Comment : @Mints97 : That s an interesting objection . The two structures in sep.h are clearly incompatible as shown in this answer although they both appear to be compatible with the structure in main.c . I always found the fact that the compatible type relation isn t transitive a little unintuitive but I ve never thought of an example like this one .", "Question : I use the following union to simplify byte nibble and bit operations : .. . .. .

Comment : give the anonymous namespace a unique name then merge the uniquely-named namespaces where there are no conflicts if desired . Comment : Pete Becker 111111 of course my question looks rediculous . But my project is ok without anonymous namespaces . They are just unnecessary . Comment : justin could you explain it more detailed . .. . Answer : 1 . No a named namespace is not the same as an anonymous namespace . The primary use of anonymous namespaces is to have all their content have internal linkage - meaning that other compilation units can not refer to it e.g . call functions . Therefore don t rename anonymous namespaces . It s like removing the static specifier from a static function . 2 . typedef struct int a void func s1 can be better replaced by struct s1 int a void func - no additional unique identifier needed . Same applies for union . The whole typedef struct def Blah construct is in fact a C remnant and not necessary in C++ . To your actual problem example : The inner struct has not much effect except perhaps introducing padding bytes . So this should be equivalent and do the job : Comment : Thnaks a lot It s just what I need : Comment : Just remeber to not blindly change code that needs not be changed . If it works as it is leave it be . If you have to work with it i.e . change it then put it under test and refactor it . But do so with thought don t just throw a name at anything unnamed that comes across your path .", "Question : The following sample code compiles just fine in Visual C++ : .. . .. . But why I d expect a compiler error because the privateData member should be inaccessible to the function main since it s supposed to be private like its container s container . I know that nameless structs are not part of official C++ but this design is asinine . By the way I ve also tried to change private into protected and struct into union : it looks like the compiler refuses to honor access modifiers on anonymous structs and unions that are nested inside another anonymous-struct or union . Can someone explain this feature Comment : This sounds like the bug that was fixed in VS2005sp1 which version are you using Keep in mind that anonymous structs are not a standard C++ feature.. .

You get the red squiggles and the message : .. . .. . Error : member Test.privateData declared at line 10 is inaccessible Comment : Are you suggesting that there are hordes of developers displaced in time who rely on access specifiers not properly cascading through two levels of anonymous structs Comment : @LightnessRacesinOrbit My understanding is there aren t hordes but a pack that like to use microsoft s workarounds and for these people they do not fix this and similar issues . Instead they mark it with their code parser Comment : @B : It just seems to me like an incredibly narrow edge case that wouldn t be worth such considerations even when there s also arguably little benefit in fixing it.. . Comment : @LightnessRacesinOrbit Good . We agree : Comment : @LightnessRacesinOrbit like Luchian Grigore notes in a comment to the question this bug can be successfully reproduced in gcc .

Answer : Anonymous structs and unions are now allowed as of C11 . Your worries will eventually go away as you migrate to a newer compiler . In GCC add -std c1x . Comment : Thanks Kerrek .

The fields in VFP allow for a width of 12 characters with 2 dp Comment : Try decimal . money data-type is obsolete . .. . Answer : @Joshua In your code we don t see how you defined the data types . We also don t see how your data types are defined in your VFP table . On VFP side although numeric float or double would work you would lose precision . Precision is important when it is money so stay away from float numeric and double data types float and numeric are worse than double . You shouldn t use them for monetary values . In VFP there is currency data type and that works quite well within SQL money range . It doesn t cover the whole range and I don t know the range it would work correctly you should try if you need all I know it is not the value written in VFP documentation .

Answer : You can t . You are setting a seed value but the chance that .NET and FoxPro is using exactly the same method to generate Random numbers is close to zero . But question is why would you want this Random is supposed to be random . Comment : the code in visual fox pro did so many use application and expect returns that result vfp Comment : It s because the random generaton in VFP is weak so same seed returns the same result each time . Which makes it less random for a random generator .

The easiest ways of exporting VFP tables to CSV don t even bring memo fields along . .. . Answer : Memo and text fields in VFP can store any character including character 0 . IOW a user might have stored binary information in a memo field . If you use VFP s copy to command then it creates a CSV delimited and a few other types for you . However copy to doesn t export fields like memo general or blob . A text file is not the best medium to export data and a CSV file when used including memo fields may not be imported by all databases . If you tell us more details how you do it and the purpose we might have better suggestions . ie : an XML might be a much better text based export .

Having no experience with FoxPro I asked about a few commands used in the code and found one of particular use : scatter memvar which made individual variable from columns in a table . Does VB have an equivalent function or do I need to create each variable with a Dim statement Edit : I should have mentioned that I m looking to use this to propagate datatables very sorry . Later in the VFP program insert into memvar matches the variables to their respective columns . I m looking to avoid the need of a method along the lines of : .. . .. . Sadly the above is how I do most of my data-entry . Edit : In response to @DRapp s comment I am using VB to read a .xin file and form an access data table from its code . There are two collections in the .xin file that are of interest to me : NamedSymbologyCollection and FeatureStylesCollection . Both of these collections are in the same line of the file so I ve written code to go tag-by-tag pick out the information I want and add it to a temporary data table . If you have any recommendations on how to improve any of the above please let me know . Comment : Can you explain what made individual variable from columns in a table means . Perhaps giving an example would help . Comment : .NET will provide the db column name and value in the resulting DataSet DataTable when you query the DB . much better than a gaggle of individual variables Comment : If i had a table column myColumn using scatter a variable m.myColumn would be made . Later in the program scatter is replaced with insert into memvar which sends all the m.variables to their respective columns . Comment : @Blackwood the old FoxPro Scatter MemVar command would actually create an unknown number of undeclared variables corresponding to the columns of a table row so that even in a VFP context many people including me would recommend not to use it anymore . belaythat I d agree with Plutonix suggesting to use strong-typing DataRow objects in .Net similar to what the VFP command Scatter Name would do which would in turn be very similar to the Model concept as described in the MVC MVVM MVP patterns Comment : Thanks Plutonix for the suggestion and Stefan for the clarification on Scatter MemVar s-function . I ll let you know how everything turns out . .. . Answer : First off I ve never dealt with FoxPro or Visual FoxPro so don t expect what I say is going to work perfectly for every scenario . Looking at this MSDN page https : msdn.microsoft.com en-us library aa978285 28v vs.71 29.aspx it looks like the to perform a simple scatter command in FoxPro you would use something like this : .. . .. . The above looks is just getting all fields that start with A and P and is excluding items matching PARTNO from the results . I think this would be best translated to a using LINQ query which could return an Object array . If you start getting into the more complicated uses of the scatter command to break up the values into a new object where the object has properties which are the same as the columns in the original table well the VB equivilent gets much harder because you ll have to make a class that inherits the System.Dynamic.DynamicObject class .

Comment : Doesn t matter - the OLEDB driver is still using the same VFP DLLs so you have that ceiling regardless .", "Question : I m making integration with application that is using ODBC Data Source - Visual Fox Pro Driver . In its dirrectory structure I ve got two dirrectories DANE and TRANS which contains .DBF files . When I am using Visual Studio 2010 Server Explorer - Data Connections to connect to DATA .DBF files everything work fine . The problem occurs when I m trying to use TRANS dirrectory - I don t see any tables When I am using DBF Viewer - there are around 30-40 tables . When I try to connect to them using connection strings : .. . .. . I can get data from DANE without problem . On TRANS I can connect to database but I ve god exception when I try to get data OleDbException - Can t read file c : Softech G POS TRANS name of table .dbf Norbert .. . .. . .. . .. . Visual FoxPro Database is abstract name of destination . That s not a database just my custom name of data source .. . Answer : The problem comes from the DSN specified . The default Visual FoxPro Database ODBC Data Source assumes a Database Container DBC is specified in the Data Source or SourceDB attributes . This equates to the SourceType http : support.microsoft.com kb 167405 attribute as in SourceType DBC . You should switch to using the Visual FoxPro Tables DSN or appending the filename for the DBC to the Data Source attribute . Also according to the Foxpro Ole Db documentation http : msdn.microsoft.com en-US library 3haz2895 28v VS.80 29.aspx you should either use Data Source or DSN but not both .", "Question : I have some Foxpro tables one of which includes a Blob field . I know the data type stored within the Blob a MapPoint file but I don t how to extract it because I don t have FoxPro not can I easily obtain it . Is there a way to take the .DBF and .FPT files and extract the MapPoint files stored within .. . Answer : This previous link shows how to connect to VFP from C http : stackoverflow.com questions 4049891 how-do-i-read-a-foxpro-8-0-database-from-c 4051836 4051836 . That answer actually shows connection with OleDbProvider which is similar to answer by DaveB however VFP is NOT SQLServer connection and uses VFP OleDbProvider which is available at Microsoft s website for VFP http : www.microsoft.com download en details.aspx id 14839 .. . .. . Used in conjunction with each other connecting to VFP OleDB and running query . The connection-string only needs to point to the physical path where the data resides and can query from any .dbf in that folder . You do not have to explicitly connect to an actual database as VFP implies a path IS the location of the database . Anyhow the other question joined with Dave should be able to get your data available and write it to a stream . The only other caveat is that the file stream that you are writing too make sure its a binary file . Otherwise anytime you write a byte that is an enter key might be forced written with a trailing line feed . I found that one out the hard way a long time ago writing binary image files when building 2d bar codes and it getting messed up .", "Question : I am executing the following Visual FoxPro SQL statement from a C program . I am expecting to get 1 result but I am not getting any results . I am able to reproduce the problem running from VFP using the following program.. . It seems that if the tables are not open before the program is executed the results are zero records . If I open the tables and only execute the SQL statement it returns the expected one record . The other thing that I would not expect is that when I run the program above the SYS 3054 12 returns the following results Notice the Cartesian product .. . But when I run the SQL statement on its own with the tables already open the output looks different notice no Cartisian product .. . .. . Final Note : There is only one record in iplclaim that matches the WHERE clause . There is only one record in iplclsub that matches the INNER JOIN iplclsub ON clause . There is only one record in ipcname that matches the LEFT OUTER JOIN ipcname ON clause and there is no record in ipcbusn that matches the LEFT OUTER JOIN ipbusn ON clause . Can anybody explain what is causing this problem and what I have to do to resolve it EDIT : .. . .. . Well I figured out the problem is the AND NOT DELETED . If I remove that clause everything works as expected . Can someone explain that and can anybody tell me an alternative way to exclude deleted records .. . Answer : There is a warning in the FoxPro documentation about the SELECT-SQL command possibly returning unexpected results when using functions like DELETED in multiple table queries . The SET DELETED ON command can be used to ignore records that are marked for deletion . With that option turned on it looks like the use of the DELETED function could be removed from the query . For the C code assuming you re using an OLEDB connection the SET DELETED ON command can be executed on the same open FoxPro connection prior to executing the query .", "Question : occupy a method made in migrating Visual Fox Pro emigrarlo to C the problem I have is how to know if the method in Visual Fox Pro : .. . .. . method is equal to dotNet : .. . .. . assuming that intValue 971 the result generated in dotNET is 2027119 but I need to be equal to that return FoxPro . Primary question : how I can make sure I get the same result Secondary question : Do you know of any online tool fox pro to prove that this method gives me result Rand Comment : so you want to know if calling the Rand function in FoxPro will return the same value as calling Random.Next in .NET I guess that depends on whether the underlying algorithm is the same which I doubt . Comment : So you want two random numbers to not be random Does not compute. . Comment : RobertMS : I also doubt that they have the same result . as I have no idea how to produce the same result in C and FoxPro so I can think illustrate my problem Comment : Why do you continue to post the same question over and over link http : stackoverflow.com questions 10903014 there-is-any-way-to-match-the-method-randint-of-visual-fox-pro-and-c-net and link http : stackoverflow.com questions 10905171 migrate-method-randint-visual-fox-pro-to-c-net .. . Answer : I m not sure why you would want to do that but here is a Visual FoxPro Toolkit for .NET http : foxcentral.net microsoft vfptoolkitnet.htm its possible it might have the same rand generator function . Comment : I do not want to depend on the application in visual fox pro I want to be independent your answer is what I have gained more hacerta for now tomorrow will prove it . . thanks D Comment : It just calls the normal c Random.Next function" ] }

In nodetool cfstats it is possible to see compression ration . Depending on data it can be for example 0.46 which means compressed data takes 46 less space . Additionall in case of column : value in newer versions column is also somehow optimized so that column name-length does not influence the table size .

Essentially what is happening is that Cassandra compacts the maps into one key- value by concatenating the key values in sorted order . This allows Cassandra to quickly retrieve and store data for you in sorted order and is also the reason for the WHERE filtering restrictions .", "Question : null .. . Answer : I want to know what is the difference between a persistent key-value DB and a wide-column DB . I understand in both DBs you retrieve a single value by a key so what is the difference between the types of the values Thanks", "Question : HBase and Cassandra are built as wide column stores using the concepts of both rows and columns . A row is composed of a key similar to the concept of primary-key in RDBMS and a value composed of several columns .. . .. . A representation can be the following : .. . .. . Is it correct at the application layer to build composed primary keys to allow to iterate quickly over colocated rows . This can be reprensented as follow . The name column moved from the Value to the Key and Value has a single column name value . .. . Answer : Composite keys are very popular in HBase schema design . They also allow you to do fast range scans on prefix component of Rowkey . Unlike Cassandra RowKey is not broken into Parts while storing data . Simple example : http : riteshadval.blogspot.com 2012 03 hbase-composite-row-key-design-doing.html .. . .. . .. . In HBase in your example you will be able to do range scans with identifier only and with identifier+name also .", "Question : HBase and Cassandra are built as wide column stores using the concepts of both rows and columns .

Is it correct at the application layer to build composed primary keys to allow to iterate quickly over colocated rows . This can be reprensented as follow . The name column moved from the Value to the Key and Value has a single column name value . .. . Answer : Compound keys are used all the time when designing Cassandra schemas . In C the keys are broken down into two parts the partition key and clustering columns . The partition key is used to hash data to nodes within the cluster . A partition is a bucket of data that can hold a single row or multiple rows based on the clustering columns . Data within a partition is local to a node and is kept in sorted order by the clustering keys which makes accessing data within a partition fast and efficient with support for range queries on the clustering keys . C also allows data fields which are not part of the compound key and are not generally used in queries unless you create a secondary index on them . The wide column terminology is a little outdated for C . In the current CQL view of things data is thought of in more traditional terms as rows in a table that are grouped into efficient to access partitions . So to answer your question yes in C it is common to move columns that might have been thought of as data columns in an RDBMS to be part of the compound key in C . To see more information on partition keys and clustering columns and how they impact the types of queries you can do see a deep look at the CQL WHERE clause http : www.datastax.com dev blog a-deep-look-to-the-cql-where-clause ." ] }

Answer : I ve been using JAK for over a year on a project . I use it to create the KML then I marshal it as just plain KML not KMZ . I created a separate utility class that uses the Java SE Zip classes to manually create the KMZ . It works just fine . A KMZ is nothing more than a .zip archive that contains exactly one .kml file and 0 or more resource files such as images etc . The only difference is that you name the file as .kmz instead of .zip when you output it . In the KML document Style definitions refer to your resources files with paths relative to the KML document itself . The KML file is considered to be at the root of the KMZ archive . If your resource files are also located in the root of the KMZ .zip then you don t need a path just the filename .

Did you try it .. . Answer : Following the javadocs https : code.google.com p javaapiforkml downloads detail name JavaAPIforKml-apidocs.zip unofficial http : www.nilab.info docs jak091130 you need to check - using instanceof - each Feature whether is is a Placemark if yes cast to it and get the Geometry which itself needs to be checked whether it is a Polygon if yes then cast to it .

I m new in Java and there are things that I don t understand at all but I ll read these jdocs to understand the api And again..... . THANKS Comment : You re welcome I have to say that this a weird API since you have to cast a Feature to see what it is actually instanceof is actually bas practice in OOP I guess those guys know what they have to deal with when they wanted to make an API for kml and the kml xml schema forced them do it this way . A good help for you would be to look at a Feature in the debugger to see what inside it . Also you have to note that there may other xml-namespaces included in a kml document such as gs xal and so on .. . They also are documented in the javadoc .", "Question : I m building an application that serves up data to a standalone Google Earth client . I want to send over an initial set of data then update it dynamically using NetworkLinkControl and Update cookie tags as things change on the server . I m generating the KML using the Java API for KML JAK library . Unfortunately while I can confirm that GE is refreshing my NetworkLink and pulling down the Updates I m sending none of my updates are showing up in GE . After lots of reading it seems like it might be that the Update s targetHref might be the issue but I m 99.9 sure I m sending over the same string . Part of what has me confused is that I ve seen conflicting info on whether or not the cookie element s value needs to be appended to targetHref . I did actually see one early prototype updating when I was serving up hand-written test KML files from a static server URL so I suspect it s not . Actually that s what s frustrating at the moment : I ve seen updating work on my own machine but can t get it working now with what looks like valid and correct KML . The current setup looks like this extraneous XML namespaces stripped for clarity CLIENT ID is a GUID-like string : .. . .. . Root KML file served from http : server kml CLIENT ID : .. . .. . Initial content KML served from http : server kmlupdates CLIENT ID : .. . .. . Later update KML served from http : server kmlupdates CLIENT ID : .. . .. . If anyone has any suggestions on what I m missing here I d greatly appreciate it . Thanks .. . Answer : My original version of the question left out two facts that turned out to be relevant : 1 I m using the Java API for KML to generate this and 2 the XML namespaces inside kml . I finally figured this out after reading this Google KML Group post http : groups.google.com group kml-support-server-side-scripting msg 22355adfe5f3bdcb for the umpteenth time . The problem is the last XML namespace xmlns : xal . For some reason removing that from the KML allows the Update tags to actually change the items in Google Earth . JAK doesn t let you change the namespaces but you can strip it manually from the marshaled string . Absolutely bizarre but at least I found a solution .", "Question : I am using Java API for KML JAK to construct KML files . I would like to be able to delete a feature using its ID but I have not found a good example of how to do so . Ideally the code would be myFolder.deleteFeatureById theID but that is not the case . Is there any better method than the following .. . Answer : In Java you need to compare strings using String.equals method not the logical operator . checks if two things are EXACTLY the same thing not if they have the same content so some string comparisons can be equal same string but test differently with .

Answer : JAK http : labs.micromata.de projects jak.html depends on the Java Architecture for XML Binding JAXB http : docs.oracle.com javase tutorial jaxb intro index.html for the underlying XML serialization .

Answer : Docutils http : docutils.sourceforge.net the reference implementation of reStructuredText upon which Sphinx is built allows you to pass options to the table of contents directive http : docutils.sourceforge.net docs ref rst directives.html table-of-contents which allow you to control how deep you want your table of contents to go into your document hierachy . From the reStructuredText documentation http : docutils.sourceforge.net docs ref rst directives.html the contents directive takes a depth option : .. . .. . depth : integer .. . .. . The number of section levels that are collected in the table of contents . The default is unlimited depth .

Also take a look at the hidden option this might be useful to control further the levels included in the table of contents . Comment : For now I m using the depth setting and with the present document structure this is not a problem . Structures where there are different depths per branch are not possible however . A practical example would be an Introduction section which I may want to subdivide but where these divisions are certainly not of the same importance as those of a Device Administration section .

Many different markup languages have been created because it is arguably more difficult to sanitize HTML . What are the advantages and disadvantages of the various different markup languages like : .. . .. . HTML http : en.wikipedia.org wiki HTML .. . Markdown http : daringfireball.net projects markdown .. . BBCode http : en.wikipedia.org wiki BBCode .. . Textile http : www.textism.com tools textile .. . MediaWiki markup http : www.mediawiki.org .. . other http : en.wikipedia.org wiki Lightweight markup language .. . .. . Or to put it differently what factors do you consider when choosing to use a particular markup language . .. . Answer : Markdown BBCode Textile MediaWiki markup are all basically the same general concept so I would really just lump this into two categories : HTML and plain text markup . HTML .. . .. . The deal with HTML is the content is already in a presentable form-for web content . That s great saves processing time and it s a readily parse-able language . There are dozens of libraries in pretty much any language to handle HTML content convert to from HTML to other formats etc . The main downside is that because of the loose standards of the early web days HTML can be incredibly variable and you can t always depend on sane input when accepting HTML from users . As pointed out tidying or santizing HTML is often very difficult especially because it fails to follow normal markup rules the way XML does i.e . improperly closed tags are common . Plain Text Markup .. . .. . This category is frequently used for the following reasons : .. . .. . Easy to parse into multiple forms from one source - PDF HTML RTF .. . Content is stored in readable plain text usually much easier to read than raw HTML if needed at some later date rather than needing to extract from the HTML .. . Follows specific defined rules where HTML can be annoying variable and unstructured .. . Allows you to force a subset of content formatting that s more appropriate in many cases than simply allowing full HTML .. . In addition to forcing a subset of HTML makes it easy to sanitize input and prevent cross site scripting problems etc . Keeping the raw data in an abstracted format means that at a later date if you for instance wanted to convert your site from HTML 4 to XHTML you only need to change the parsing code . With HTML formatted user input you re stuck now having to convert all the HTML to XHTML individually which as HTML Tidy shows is not always a simple task . Similarly if a new markup language comes along at some point or you need to move to an alternative format RTF PDF TeX an abstracted restricted subset of text formatting options makes that a much simpler task . Bottom line is what is the user input being used for . If you re planning to keep the data around and may need to shuffle formats etc . then it makes sense to use a careful abstract format to store the information . If you need to work with the raw data manually for any reason then bonus points if that format is easily human-readable . If you re only displaying the content in a web page or HTML doc for a report etc . and you have no concerns about converting it or future-proofing it then it s a reasonable practice to store it in HTML .", "Question : I m developing a wiki with Python Django partly for educational purposes . Up to now I m still missing the right markup language . I tried quite a view including Creole and Markdown which worked well except for the table support .

But the users of my wiki want to be able to create tables with bigger formatet text and lists within the cells . I have my problems with finding a markup language which actually can do this . I ve gazed upon the MediaWiki markup language which seems to support everything but I think using this would be overkill .

I would rather have a nice markup language with a lightweight Python implementation . Does anyone know of a markup language with extended table support and an implementation in Python which I could use Thanks in advance .. . Answer : I don t know if it meats your needs but you could use reStructuredText http : docutils.sourceforge.net rst.html . Sphinx http : sphinx.pocoo.org generates html from it for the python documentation and its written in python so it should be easy to use for this purpose .

Comment : I suppose the exact definition of a markup language is a bit varied so I don t know if rest does technically fall into this category but its easy to write easy to read and compiles to good-looking html so its probably quite a good candidate for this sort of usage . Comment : Thanks for the suggestion . reST does indeed support everything I need and has even integration in Django . However I don t find it that easy to read for non-techies and even harder too write if you look at the actual markup for a complex table .

I would like to know how Python developers do that Anyway thank you Comment : Yes complex tables are a bit tricky but so far I have never actually needed to use one .

Answer : I have found a solution myself since I found reST to complicated to use for technically inexperienced users . I might be a bit elaborate but it works for me . The key is an extension for an already existing markup language . I found Markdown rather pleasant despite its lack of table support . Using Python-Markdown here http : freewisdom.org projects python-markdown Writing Extensions is everything you need to know for writing your own extension . It s not that complicated . I hacked something together in half an hour and it actually works so far . I would show the code here but I m not really proud of it yet Basically you parse a markup block and insert the table elements in the DOM as you like . I guess every usable implementation of a markup language should have some kind of extension mechanism so it should be possible to write extensions for other languages and implementations too .

Maybe ending tags missing Comment : I will look into using macros thanks The problem is that when I got to insert a new piece of markup Confluence wont format the text if there is a large amount of text . Comment : Let me know if you need me to explain my situation in more details I m quite new to confluence . Comment : I haven t had to opportunity to insert such big amount of markup go for some hardcoded macro like load all your lines in some java objects and render them into a velocity file or even hardcode them in the velocity file .

I ve done a little bit of reading but if I were to start using HTML5 right now what could I do to support semantic-markup such as microformats and Semantic Web technologies such as RDFa If I want to utilize these technologies now should I stick with XHTML Comment : If you ve not already found it see dev.w3.org html5 rdfa http : dev.w3.org html5 rdfa .. . Answer : Some years have passed .. . .. . For semantically annotating your content in HTML5 documents you can use Microdata Microformats and or RDFa : .. . .. .

It s still included https : html.spec.whatwg.org multipage microdata.html microdata and potentially under development in WHATWG s HTML Living Standard . Microformats http : microformats.org as in class values are obviously supported as these don t require any changes to the HTML language .

It can also be used in the form of the subset RDFa Lite http : www.w3.org TR 2012 REC-rdfa-lite-20120607 . All relevant specifications are W3C Recommendations .", "Question : When you are developing a web-based application and you want to allow richly formatted text from the user you have to make a choice about how to allow that input . Many different markup languages have been created because it is arguably more difficult to sanitize HTML . What are the advantages and disadvantages of the various different markup languages like : .. . .. . HTML http : en.wikipedia.org wiki HTML .. . Markdown http : daringfireball.net projects markdown .. . BBCode http : en.wikipedia.org wiki BBCode .. . Textile http : www.textism.com tools textile .. . MediaWiki markup http : www.mediawiki.org .. . other http : en.wikipedia.org wiki Lightweight markup language .. . .. . Or to put it differently what factors do you consider when choosing to use a particular markup language . .. . Answer : Many different markup languages have been created because it is arguably more difficult to sanitize HTML . Really How is it difficult There are functions to remove potentially dangerous attributes or tags and validate the HTML before you enter it in database or file . Can you give me examples of how it is difficult to sanitize HTML", "Question : Suppose you re developing a web site and blind users will be a significant chunk of your target market . If the web site includes document editing functionality what would be appropriate WYSIWYM http : en.wikipedia.org wiki WYSIWYM tools Are languages like Markdown http : daringfireball.net projects markdown dingus Textile http : textile.thresholdstate.com and Wiki Formatting http : www.mediawiki.org wiki Help 3aFormatting really accessible or are they inconvenient to blind users Comment : I ll just note that blind people are usually not interested in formatting or display options . I d guess that simple text entry would be sufficient . Comment : @Gilbert Le Blanc - Agreed . But this is why I asked about WYSIWYM http : en.wikipedia.org wiki WYSIWYM instead of WYSIWYG http : en.wikipedia.org wiki WYSIWYG there are still markup languages for annotating content denoting headers code blocks quotations etc.. . in a non-presentation way . .. . Answer : the first question is : how important is semantic structure could you get away with plain text . You could do simple parsing like treating blank lines as paragraph markers treating a series of lines which begin with as a bulleted list identify URLs and make them into links etc . As a blind developer myself I have no problem in understanding languages like Markdown . But if it s a syntax I m unfamiliar with I ll only learn it if I expect to use the site very often or care deeply about the content . Two final thoughts come to mind : while I certainly experience some accessibility challenges using TinyMCE you could develop something much simpler - provide less than 10 formatting options like inserting hyperlinks making lists centering text setting the style such as heading etc . And lastly when I talk to non-technical blind people they often just write their content in Word and paste into a wiki or blog post . This sounded strange when I first heard it but it does make sense . So an ideal solution would accept pasted in content . In closing - it depends how important this is and how much effort you want to expend . Maybe a Markdown editor with a live-preview like on this site buttons for inserting simple formatting like URLs and the ability to paste in rich text would tick all boxes : - Comment : +1 for leveraging what they re already using and supporting rich copy-paste Comment : I think it would be a bit better to strip down some mature markup language . Then you get ready to use tools and some of users may already know this markup language . And if they do not they can find lots of info about them . Otherwise you need to test your own implementation . And write DOCUMENTATION.. . So just trim something existing first", "Question : I am using Confluence to display a list of items taken from an XML file where each item is displayed as a small table containing its appropriate attributes .

If you re not seeing Apple push notifications when you re connected to a network check with your network administrator to make sure related TCP ports are accessible . To use Apple Push Notification service APNs your Mac and iOS clients need a direct and persistent connection to Apple s servers . iOS devices try to connect to APNs using cellular data first . If the device can t connect to Apple s servers over the cellular connection it then tries to connect using Wi-Fi . If you use Wi-Fi behind a firewall or a private Access Point Name APN for cellular data you ll need a direct unproxied connection to the APNs servers on these ports : .. . .. . The APNs servers use load-balancing so your devices won t always connect to the same public IP address for notifications .

I am following this great tutorial by Ali Hafizji on using APNS service for push notifications http : www.raywenderlich.com 32960 apple-push-notification-services-in-ios-6-tutorial-part-1 .

A sidenote : i took the entrust root certification authority.pem from https : github.com jonathanrcarter push2press the correct address to look for it would probably be https : www.entrust.net downloads binary entrust 2048 ca.cer they are the same thing anyway . In this case application was running in debug mode on device run from XCode and everything was working fine . Testing APNS in production mode : .. . .. . To test APNS in production mode i archived the app for AdHoc distribution and installed it on device with iPhone Configuration Utility http : support.apple.com downloads iphone 20configuration 20utility .

Of course i also made sure that when i was testing the production mode the correct device APNS token - device APNS tokens in debugging and production mode are not the same - was used .

Tried to connect ssl : gateway.push.apple.com : 2195 via telnet just to make sure : connection was fine . It became obvious : it is a certificate problem . .. .

If you re here your problem is obviously just the creation of the .PEM file and all the tutorials make it seem like this has to involve multiple-files and commands .

This is the error when I run my server : Comment : Did you use an Ad-Hoc provisioning-profile with this build Else a production certificate will not work . Comment : @edwardmp yeah I think that is the problem . .. . Answer : The most likely explanation is that you are sending a push-notification with a sandbox device token to the production APNS server . Either you are using an old device token that was sent to your server by your app while you were testing it in the sandbox environment or your app is still signed with a development provisioning-profile and is still receiving sandbox device tokens from the APNS service . My answer assumes that you are using a device token that originated from the APN service and not some dummy token you created yourself . I suggest you check the provisioning-profile to see what value appear for the aps entitlement . I also suggest you clear your db from any old device tokens . Comment : hmm.. . Now it s not throwing an error that I changed to the sandbox but my device still isn t receiving the notification as far as I can tell . Comment : @JasonSilberman What exactly did you change to the sandbox The app or the server If you re using the wrong certificate at the server using sandbox push ceritificate to connect to the production APNS server or vice versa the device won t receive anything and the server won t get any error response .

The following code is derived from there : .. . .. . Note that the example recommends that you make sure to set the stream to non-blocking mode with stream set blocking fp 0 before reading from it but that s only necessary if you want to do any interim error checking your code example does not do this so it may not be an issue for you . Comment : When i echo the response using fwrite i got response code of 485 what this mean Comment : The fwrite function http : php.net manual en function.fwrite.php returns the number of bytes written to the stream . What this means is that the length of apnsMessage is 485 bytes but has nothing to do with the response from the APNS server . You need to use fread to get the server response as shown above .

I m using a dedicated-server to send push-notification to ios devices . From this server I can successfully connect via telnet to the APNS gateway : .. . .. . I ve correctly generated the CA certificate and the combined cert and key from apple and I can test an OpenSSL connection using them correctly : .. . .. . I can also use Mac Os X Pusher https : github.com noodlewerk NWPusher to succesfully send push notifications using that certificates from my development box . I tried to use ApnsPHP using a modified version of their sample code : .. . .. . This results in an error when invoked from console : .. . .. . This is quite weird I ve tried several minor fix including commeting out the verify peer section in Abstract.php but none worked . I am missing something here have any of you any idea on how to fix this I ve been sending push-notification from Java and Python for a while so I m quite confident about the whole process . It s my first time with PHP anyway . Comment : Does your PHP have SSL and TLS support Comment : elbuild.com luca info.php http : elbuild.com luca info.php i believe it has . AM i correct Comment : Yes it has TLS and SSL support . Comment : Do you have a firewall blocking the ports Comment : According to the fact i can Connect via telnet i would say no . Have you seen the top part of my post .. . Answer : I know this is an old post but still I am contributing my comments to send push-notification for iOS iPhone as I have gone through the same issue once : .. . .. . I was able to connect through telnet over apple sandbox server but not with PHP socket script as it was giving gateway connection error . Please follow below steps : .. . .. . 1 . Check PHP configuration ini so as to confirm SSL and socket enabled . 2 . No firewall related restriction . 3 . Try some core PHP test notification separately . You may find one here http : prashantpandeytech.blogspot.in 2015 09 iphone-ios-and-android-push.html .. . 4 . Now openssl should verify your pem and passphrase should be confirmed . Note : if you have generated IPA for your APP then try with your production pem rather than development pem .", "Question : I m having trouble with using APNS with PHP and getting the following message : .. . .. . The problem only happens sometimes and other times it would actually send the push . Since I have the test script on a loop of 10 iterations I would sometimes get this : .. . .. . I m testing using the sandbox server tls : gateway.sandbox.push.apple.com : 2195 .. . .. . Here is what I tried : .. . .. . I tried to reissue the PEM and all certificates with it . I played around with the request protocol sslv3 : and tls : . I played around with the passphrase push worked without the passphrase btw .. . I tried searching stackoverflow for a solution and nothing worked . Checked pem file-permissions 644 .. . Checked pem parent directories permissions 755 .. . .. . It seems that all the solutions I found on Google and SO are people having problem pushing altogether . I feel like the service is rate limited maybe Because we waited a while around 15 minutes and then tried it again and was able to successfully push around 100 messages until I started getting that message again . Comment : Have you found a solution for this Samer My situation looks so much like yours Well in fact I was able to send apns sometimes but lately I realized my script spent months trying to send apns one at a time even after my certificate has expired...I m asking myself if Apple just blocked my IP and maybe now I stopped trying to connect they will unblock my IP after a certain amount of time.. . Comment : Nevermind check my answer about changing Apple s servers Now I use ssl : api.push.apple.com : 443 instead of ssl : gateway.push.apple.com : 2195 .. . Answer : The sandbox push service is rate limited . I have experienced this myself when testing but have never encountered any such limit using the production API . You might also be hitting their other protections . Are you opening a connection sending a message closing connection and then looping and doing it all over again That will get your notifications dropped . Apple wants you to send several push notifications using the same connection not a new one each time . Best Practices for Managing Connections .. . .. . You may establish multiple connections to the same gateway or to multiple gateway instances . If you need to send a large number of remote notifications spread them out over connections to several different gateways . This improves performance compared to using a single connection : it lets you send the remote notifications faster and it lets APNs deliver them faster . .. . Keep your connections with APNs open across multiple notifications don t repeatedly open and close connections . APNs treats rapid connection and disconnection as a denial-of-service attack . You should leave a connection open unless you know it will be idle for an extended period of time for example if you only send notifications to your users once a day it is ok to use a new connection each day . From Apple Docs @ https : developer.apple.com library ios documentation NetworkingInternet Conceptual RemoteNotificationsPG Chapters CommunicatingWIthAPS.html Comment : That makes sense I usually keep the connection open until sent to all devices so should be good on that part . Let s hope production is good . Thanks Comment : lol sorry didn t know i had to press the bounty button to award it . I thought it was automatic . Comment : As said in @greg diesel answer Apple wants you to send several push notifications using the same connection not a new one each time . Many libraries use stream socket client to send messages with option STREAM CLIENT CONNECT . Try to change it to STREAM CLIENT PERSISTENT" ] }

I believe it has the option for site wide contact form and user contact form .", "Question : When submitting a message in my site-wide contact form in Drupal 6.x I get the following message along the top of every message : .. . .. . Name sent a message using the contact form at www.mysite.com contact .. . .. . I would like to remove this message . Looking around I ve found it comes from the contact.module here : .. . .. . I ve done a bit of research and it seems that I need to create a custom module with a hook mail alter function to edit the contact.module . When it comes to this I get a bit lost . Could anyone kindly take me through the steps to accomplish the task Many thanks . .. . Answer : I did something like that recently . Here is a template you can use to get what you need . Most is from the contact module . The code below is from Drupal 7 but should work as is in Drupal 6 . Comment : thank you for the reply . So how do I go about using this Where do I paste this code Comment : @Chris : you should paste it in your own module s file . For example if the module s name is modulename like in googletorp s code you should paste it in the modulename.module file but you should first learn how to create a simple module : drupal.org node 361112 http : drupal.org node 361112 there s the appropriate link-to other Drupal versions too", "Question : I m new to Drupal . I want to create a contact page so I copied page.tpl.php and renamed it to page-contact.tpl.php . I created some new elements in the page so I can see that if I click on the contact link I ll know that I went to the correct page . Right now I don t see any change . Was there something I missed Do I need to do something in the admin settings so Drupal knows which file I need to open I also tried clearing my cache . .. . Answer : In theory this is a valid approach . Problem is you ll be able to create a new layout for your contact page this way but not necessarily change the contact form . If you wish to alter the form as well I d recommend using the webform module . It s pretty flexible when it comes to creating contact forms plus it creates a node so you can style it with ease either in you standard node.tpl.php or - even better - in node-webform.tpl.php . This is what I usually do . There might be other solutions too but it would help if you made it clear what kind of alterations you wish to introduce in your contact page .

Answer : If you visit admin build contact settings in Drupal 6 or 5 you can untick Enable personal contact form by default", "Question : So I ve gone and customized the user login pass register pages Drupal 6 and no problems . However I now do the same thing with the contact mail page contact module enabled and all I get is the contact form and NO theme . What am I doing wrong .. . Answer : It looks like you are creating a module rather than a theme . With drupal6 you can extend an exsisting theme negating the need for you to try and override the theme for each item . Have a look at base theme in the theme .info http : drupal.org node 171205 base-theme file and the documentation on creating your own theme http : drupal.org node 171179", "Question : I have a content-type in my Drupal 8 site called TeamMember which represents and employee at the company .

I just wrote whatever information I wanted and it worked .. . Answer : My suggestion ditch the contact form and go for Webforms http : drupal.org project webform You will thank me in the long run . Comment : It has an option to send the mails to multiple people . And list the submissions and so on . Comment : yeah I ve seen others telling me that but it s like a challenge for me not a big one to do this I really wanna learn drupal Comment : Webform is a breeze . Not much learning cureve involved for basic functionalities . Most of the stuff can be done from admin interface :", "Question : What would be the best way to construct a contact form in Drupal 6 for each node of a particular type I have some CCK nodes of type profile which have email-address as a field . I want to have a view for each node with a contact form that users can fill out and send with their own email-address as a return address so that further contact is being done offsite . Basically I just want that initial email contact to be done through my site and when the recipient replies it just goes to the address that the sender entered when they filled out the contact form . You might be asking yourself why I don t use the personal contact form that comes baked into Drupal . The issue is that the way my institution deploys their Drupal instances to use the local Kerberos logins the user accounts it creates in Drupal do not have email addresses . They just get a basic skeleton account with username . I don t really want to force users to go through another hoop of editing their user account info because they most likely just won t do it . .. . Answer : There is nothing to do particularly with node itself all you need for this - is form with fields from to subject message and custom submit handler for this form . you can implement all this in custom module using forms API http : api.drupal.org api drupal developer--topics--forms api reference.html 6 to create form and write custom submit for it . And in this submit you need to send email via drupal mail http : api.drupal.org api drupal includes--mail.inc function drupal mail 7 - take a look at this it is provides examples as well . That http : api.drupal.org api drupal includes--form.inc group form-api 6 topic can help you with forms . Then if you need to place this form within a node you can do the following : via hook nodeapi http : api.drupal.org api drupal developer--hooks--core.php function hook nodeapi 6 on view operation add form you ve created before you can check for particular node type and use existing field values you mentioned cck field with email to pre-fill form . So that every time user views node he sees this form . as logical continue of your task I suggest it makes sense to take a look at menu system http : api.drupal.org api drupal includes--menu.inc group menu 6 and create local task tab for the node where you ll display email form . In general that s all . There are of course other ways of implementing this however I think this one is the easiest for understanding . Regards Slava Comment : Thanks Slava . I was hoping I could do this without writing a custom plugin as I m very new to Drupal but I think you re right that this is going to probably be the way to go . I ve started researching the process of creating modules and much of what you explain here is starting to make more sense . Thanks .", "Question : I enable the contact form module and it isn t showing up unless I m logged into the system . I want all users to be able to use it . .. . Answer : You ll need to allow anonymous and for good measure authenticated users permission to see it via the Drupal permissions admin page . Comment : yup - just figured that out as I was coming back in here to add a comment . : -", "Question : So I ve gone and customized the user login pass register pages Drupal 6 and no problems . However I now do the same thing with the contact mail page contact module enabled and all I get is the contact form and NO theme . What am I doing wrong .. . Answer : To theme a full page you shouldn t need to add that item into your code at all in fact it may be the reason you re not getting any theme - your item is conflicting with the default behaviour . Presuming the url for your contact page is http : www.your-site.com contact just create page-contact.tpl.php in your theme directory ..and clear the theme registry gets me every time . This goes for all pages - create a template based on page.tpl.php and named after the url arguments . For example page-taxonomy-term.tpl.php will be used to theme http : www.your-site.com taxonomy term . Comment : I tried to add a node-contact.tpl.php file but Drupal isn t using it . Comment : EricP : there are a whole stack of reasons why it might not be working but without knowing your setup it s difficult to pinpoint . Upshot : node-contact.tpl.php to theme just the content of a page which I assume is what you re trying to do isn t a default template format . You can use node- content-type .tpl.php or node- nid .tpl.php to theme the content for specific types or individual nodes . If you want to re-theme just the content of a non-node contact form the fastest option is to use a form alter hook .", "Question : I m building a site and it has a contact page . the contact page uses contact module and it has some basic forms what I want is to add some simple text like my personal email and phone-number and .. . to this page but I couldn t find a way to do it .

I just wrote whatever information I wanted and it worked .. . Answer : You can also create a block add it above or below the form then add your information to it . Simplest solution if you all you need is an area to add some details ." ] }

Anyway I see a lot of examples to embed the camera into the page w getUserMedia so I don t know if I can rely only on the first method .

I was confused by this link : developer.mozilla.org en-US docs Web API Navigator getUserMedia https : developer.mozilla.org en-US docs Web API Navigator getUserMedia I didn t understand it just changed the name but it s the same class Comment : It returns a promise rather than taking success and failure callbacks but otherwise is the same . .. . Answer : Using the WebRTC getUserMedia API is going to cover all modern browsers apart from Safari : http : caniuse.com feat stream .. . .. . Here https : mdn-samples.mozilla.org s webrtc-capturestill is an example page that uses getUserMedia to take a still picture with a link-to a page https : developer.mozilla.org en-US docs Web API WebRTC API Taking still photos describing the code . Most getUserMedia demos show the video stream in a visible canvas area but that s not required . You can capture an image using getUserMedia without displaying the video stream in a visible canvas . Unfortunately Apple has been slow to adopt WebRTC APIs so I think the file input tag is about the best your can hope for there unless you are willing to use something like Cordova . Here https : www.raymondcamden.com 2013 05 20 capturing-camerapicture-data-without-phonegap is a description of how to use the file input tag . The Media Capture API https : www.w3.org TR html-media-capture is a candidate recommendation which means it is on its way to becoming a standard however I don t know of any browsers that implement the current W3C recommendation using a bare capture attribute in the input tag . The input-type-file accept image style currently only seems to be supported by mobile browsers . In summary if you want to have broad browser support in the near future you are going to need to support both methods until Apple starts supporting WebRTC APIs or until other desktop browsers start supporting the Media Capture API or the variant with the capture attribute that is currently supported by mobile browsers . Comment : As far as I understand getUserMedia API allows to embed the camera output into the webpage . Because I don t need to embed anything but just acquire and process in background a still image I think the first method is still better . Comment : @Mark I updated my answer . If you want broad browser support in the near future unfortunately you ll probably need to support both methods . Unless your use is just mobile in which case the input tag method may suffice although it may change slightly at some point given the W3C recommendation . I also noted in my update that getUserMedia doesn t need to show the live video . Most demos show it because it s more interesting that way for demo purposes .

I found that there is no example code which works . Is there any browser supporting Here is my code Comment : I too am looking for a tutorial on how to do this . .. . Answer : getUserMedia gives you access to the device but it s up to you to record the audio . To do that you ll want to listen to the device building a buffer of the data . Then when you stop listening to the device you can format that data as a WAV file or any other format . Once formatted you can upload it to your server S3 or play it directly in the browser . To listen to the data in a way that is useful for building your buffer you ll need a ScriptProcessorNode . A ScriptProcessorNode basically sits between the input microphone and the output speakers and gives you a chance to manipulate the audio data as it streams . Unfortunately the implementation is not straightforward . You ll need : .. . .. . getUserMedia https : developer.mozilla.org en-US docs Web API Navigator.getUserMedia to access the device .. . AudioContext https : developer.mozilla.org en-US docs Web API AudioContext to create a MediaStreamAudioSourceNode and a ScriptProcessorNode .. . MediaStreamAudioSourceNode to represent the audio stream .. . ScriptProcessorNode https : developer.mozilla.org en-US docs Web API ScriptProcessorNode to get access to the streaming audio data via an onaudioprocessevent . The event exposes the channel data that you ll build your buffer with . Putting it all together : .. . .. . Rather than building all of this yourself I suggest you use the AudioRecorder https : github.com cwilso AudioRecorder code which is awesome . It also handles writing the buffer to a WAV file .

Answer : A solution I have found is to call getUserMedia with video and audio enabled if the call fails meaning that they either don t have a camera or a mic then you call getUserMedia again from the failure callback that you provide requesting access to the microphone only . Of course you can handle successes and failures however you like . NOTE : if there is no camera the pop-up requesting the initial camera feed that will fail never occurs . So the user will only get one request for access which makes this solution a tad bit more palatable . Comment : exactly like the only solution I can imagine in this situation but it seems a bit rough for me.. . Comment : the options to enable audio or video in the constraints are Boolean only . It sucks but it is the way it was designed .

The old way still works as well but this may be a bit cleaner . Note that is using enumerateDevices https : developer.mozilla.org en-US docs Web API MediaDevices enumerateDevices which in Chrome at this time requires enabling a flag or using adapter.js https : github.com webrtc adapter blob master adapter.js . Update : Chrome now supports enumerateDevices as well .", "Question : I am trying to use media streams with getUserMedia on Chrome on Android . To test I worked up the script below which simply connects the input stream to the output . This code works as-expected on Chrome under Windows but on Android I do not hear anything . The user is prompted to allow for microphone access but no audio comes out of the speaker handset speaker or headphone jack . In addition the feedback beeps when rolling the volume up and down do not sound as-if Chrome is playing back audio to the system . Is it true that this functionality isn t supported on Chrome for Android yet The following questions are along similar lines but neither really have a definitive answer or explanation .

Answer : Chrome on Android now properly supports getUserMedia . I suspect that this originally had something to do with the difference in sample rate between recording and playback which exhibits the same issue on desktop Chrome . In any case all started working some time on the latest stable around February 2014 . Comment : It currently 12 09 2014 - Version 37 does not stream video on android - the same code works in desktop pc chrome but not android chrome .", "Question : From MDN s page on Navigator.getUserMedia https : developer.mozilla.org en-US docs Web API Navigator getUserMedia : .. . .. . Deprecated .. . This feature has been removed from the Web standards . Though some browsers may still support it it is in the process of being dropped . Do not use it in old or new projects . Pages or Web apps using it may break at any time . .. . So how in heaven can we access user media in browsers I see around some webapps that are perfectly capable to detect a smartphone camera so what is the solution For example this doesn t work anymore http : www.html5rocks.com en tutorials getusermedia intro Comment : MDN : Navigator.getUserMedia https : developer.mozilla.org en docs Web API Navigator getUserMedia tells you : This is a legacy API for backwards compatibility . Please use : MediaDevices.getUserMedia https : developer.mozilla.org en docs Web API MediaDevices getUserMedia Comment : Did you check the link MediaDevices has no support in mobile browsers at all and limited support on desktop browsers . Comment : Browser vendors wont adapt new features immediately and also wont kick out deprecated ones immediately there will always be a transition time . MediaDevices.getUserMedia is the new standard way you have to do it . To support as many browsers as possible while still staying up to-date you would first test for the existence of MediaDevices.getUserMedia and use it if possible and otherwise fall back to Navigator.getUserMedia Comment : Please post a link-to a demo that actually works and uses this technology . I can t find any . Comment : MDN : Navigator.getUserMedia : Examples https : developer.mozilla.org en docs Web API MediaDevices getUserMedia Examples has an example that will use the new API or the old one as fallback first asking for permission to access the camera otherwise you won t be able to detect if there is a camera and then streaming it to a video element . Camera detection without permission of the user might only be possible with flash . But even that is either already disable by default or will be in future . .. . Answer : The state of the art at the moment is navigator.mediaDevices.getUserMedia https : developer.mozilla.org en docs Web API MediaDevices getUserMedia using the adapter.js https : github.com webrtc adapter polyfill which is a shim more than a library in that its goal is to disappear once all browsers are up to spec http : iswebrtcreadyyet.com promisegum . The following works in Chrome Chrome for Android Firefox Firefox for Android Edge and Opera use https fiddle https : jsfiddle.net srn9db4h in Chrome : .. . .. . .. . navigator.mediaDevices.getUserMedia video : true audio : true .. . .then stream video.srcObject stream .. . .catch e log e.name + : + e.message .. . .. . var log msg div.innerHTML + msg + br .. . .. . .. . script src https : webrtc.github.io adapter adapter-latest.js script .. . video id video width 160 height 120 autoplay video br .. . div id div div .. . .. . The spec has settled so the main reason for the polyfill is that Chrome is catching up see this Google Developers post on choosing input-devices https : developers.google.com web updates 2015 10 media-devices hl en . The difference is the return of a promise and the new constraints syntax http : stackoverflow.com questions 28282385 webrtc-firefox-constraints 28911694 28911694 . Chrome Canary 52 supports mediaDevices.getUserMedia and video.srcObject natively . Chrome for Android still needs the polyfill . The old navigator.webkitGetUserMedia Chrome Opera navigator.mozGetUserMedia Firefox and navigator.getUserMedia Edge are around for backwards compatibility for now ." ] }

Fragment rule can only be used in lexer rules or other fragment rules .. . you re setting static lexer-variables from the parser : you cannot do this The parser buffers tokens at its own will causing your logic to go horribly wrong . There is a strict separation between the lexer and parser : the lexer simply produces tokens without any interference from the parser Lexing is a separate process . If you do want that choose something other than ANTLR Google for scannerless parsing PEG and or packrat . This problem is most probably why L isn t being tokenized as a TYPE in your particular case .. . you re using literal tokens like W w but also a LETTER as a lexer rule . However a single w or W will now never be tokenized as a LETTER since . Defining literal tokens inside parser rule is more or less the same as doing : .. . .. . W : w W .. . LETTER : a . . z A . .

The only way to get the driver version in these cases at least on Windows seems to be via the file metadata information of the driver DLL . The drivers on other platforms do not even have this file metadata . So is there a way to get the driver version using ODBC when we are not connected Thanks Ed .. . Answer : The ODBC API doesn t support this interrogation until the connection is live . There are tricks you can bring to bear such as those used by the iODBC Administrator.app on OS X http : www.iodbc.org dataspace iodbc wiki iODBC Downloads Mac OS X .

Answer : I would recommend you stick with iODBC the ODBC driver manager Apple has shipped as part of OS X since Jaguar 10.2 . The version Apple bundles into Yosemite 10.10 remains a bit behind at 3.52.6 so I would also recommend you update to 3.52.10 http : www.iodbc.org dataspace iodbc wiki iODBC Downloads Mac OS X . iODBC and UnixODBC are built to be API equivalent so you should just need to ensure that your drivers and DSNs are properly configured in the iODBC locations optimally via iODBC Administrator.app Applications iODBC .

Answer : I m using distutils to distribute a python C extension library that requires to link against the ODBC Driver Manager available in the user s system if any .

I ve tried all manner of things suggested in blog posts and SO posts.. . creating DSNs in ODBC Administrator creating a .odbc.ini attempting to use unixODBC which didn t work with PyODBC specifying a connection-string instead of keyword args etc . I also produced a trace file through iODBC which I have pasted here http : dpaste.org DSbC6 but I couldn t glean any more information from it than from the error message . I should mention that I am tunneling the connection to SQL Server over SSH with the line LocalForward localhost : 1433 production.someinstitution.edu : 1433 in my .ssh config since my IT department has limited me to connect only from the production server s IP . It works for a GUI client SQuirreLSQL so I assume the forwarding is correct . Comment : Have you specified port in pyodbc connection-string Comment : I knew it had to be something simple I was missing Thank you so much sunprophit . Noted for future reference : FreeTDS or iODBC doesn t have a concept of default port for a driver . Comment : @sunprophit : Just checked and it s working perfectly now Can you post that as an answer so I can vote up accept it Comment : What did you do to get iODBC to find the driver Is there a config file you need to edit after you install FreeTDS via homebrew .. . Answer : You should use port parameter in connection-string in case of DSN-less connection . Otherwise your port could be specified in your DSN or driver config odbc.ini and freetds.conf respectively Comment : Part of the reason it took so long to find this was that the exact code worked on my server with Ubuntu and unixODBC with FreeTDS . There I could omit the port-number and things would still work .

Answer : I m trying to compile MySQL ODBC support into Stata on a Solaris machine . The only relevance that Stata has here is that the Solaris version is compiled as 64-bit binaries so everything that it touches has to be 64-bit as well .

I found out I had to install PHP and have been reading the documentation from the virtuoso GitHub README.php5 https : github.com openlink virtuoso-opensource blob develop 7 README.php5 to setup PHP on the virtuoso server . This is my first time setting up PHP and I have run into an issue when trying to run the make command . I am in directory etc php-5.2.10 and have been able to run the configure command with all the flags . The error from the make command I receive is : .. . .. .

I have run sudo find -iname iodbcext.h to try and determine where that file may be located and the only result I get back is usr include libiodbc iodbcext.h . However I am not sure if that is what make is looking for or if there is supposed to be another one within the php-5.2.10 directory that is used and if that is the right one what would I do with it Any assistance or advice in getting PHP setup on the Virtuoso server is greatly appreciated . Comment : The version of PHP you re trying to install is ancient it was released in June 2009 . It s not even the most recent release in the 5.2 branch . Why are you trying to install this old of a version Comment : I was just trying to follow the version that was presented Readme.php5 file I linked that s the only reason I was using it as I am not very familiar with Virtuoso as well so I did not want to stray from the instructions . Comment : The PHP features of Virtuoso have been largely untouched since 2011 https : github.com openlink virtuoso-opensource commits develop 7 binsrc hosting php when they added initial support for PHP 5.3 . PHP 5.3 reached end-of-life over a year ago . http : php.net eol.php I don t think the PHP functionality in this software is maintained at all and it may be too bit-rotted to use . Comment : Virtuoso relies on the external PHP libraries which process the script files typically from Virtuoso s DAV repository or from the local filesystem . Any PHP 5.x which is the current production version should work and we do recommend the latest stable version . Guesses on SO as from @duskwuff tend not to be as accurate as anyone might wish .

Comment : @TallTed Are you implying that the commit adding initial support for PHP 5.3 in 2011 actually added complete support for PHP 5.3 5.4 5.5 and 5.6 the latter three of which didn t even exist in 2011 .. . Answer : You have conflicting packages installed for the iODBC http : www.iodbc.org and unixODBC http : www.unixodbc.org driver managers . It is strongly advised that you choose one or the other . Given that you re using Virtuoso http : virtuoso.openlinksw.com from my employer OpenLink Software http : www.openlinksw.com I d advise that you settle on iODBC also maintained and supported by OpenLink Software http : www.openlinksw.com and generally expected to be found by Virtuoso . PHP doesn t include the iODBC SDK libiodbc-devel.x86 64 which is where the header file iodbcext.h would be found . I should note that the current version of iODBC is 3.52.10 somewhat later than the package you ve installed.. . It s not clear what options you passed to configure to get the make script you re running . You may be able to get past the error reported above by editing the second occurrence of -I usr local iODBC include in the make script changing it to -I usr include libiodbc .. . but this is something of a guess . Comment : Hi @TailTed I just was told about Virtuoso s VSP markup as well . Would this be a better way to look into getting my HTML form-data to my Virtuoso server than dealing with PHP So far I have found 14.3 VSP docs.openlinksw.com virtuoso vsp1.html http : docs.openlinksw.com virtuoso vsp1.html page that goes over some of the basic markup for VSP . Comment : Also I had already changed my configure to include -I usr include libiodbc for the second occurence I believe that s how I got past any errors the first time but then had issues with the make -ing it . I now am trying with php-5.6.15 and have removed the unixODBC package and now am getting configure : error : Cannot find header file s for pdo-odbc again . Comment : Better is always a judgement call . At OpenLink we believe in horses for courses -- use the best tool for the job you re doing . I don t know nearly enough about what you re doing to say whether PHP which you may already know or VSP which it s clear you don t know yet or some other script markup is better . Again I encourage you to raise your questions to a broader audience of Virtuoso-knowledgeable people on the mailing list https : lists.sourceforge.net lists listinfo virtuoso-users or the OpenLink Support forums http : boards.openlinksw.com support . Comment : About Cannot find header file s for pdo-odbc I can only guess because you still provide only partial information . Best guess is that your configure command left something out I think you need something like --with-pdo-odbc iODBC usr local iODBC where you likely had --with-pdo-odbc iODBC .. .

This only seems to happen in Firefox and not in other browsers . Comment : Are you using embedded css and js or external links Linking externally will help cache the styling and js on the client browser .. . Answer : Some people like to call this the FOUC Flash Of Unstyled Content . If you are using Google Fonts embedded via javascript resource https : developers.google.com fonts docs webfont-loader then it adds a class to the html tag that allows you to hide content whilst the scripts are loading using normal rules like html.wf-loading content display : none . However in my experience this isn t bombproof though . The only way I ve found to fairly consistently achieve no FUOC during is to convert your fonts to BASE64 and embed that directly in your CSS Font Squirrel provide a great resource for doing this http : www.fontsquirrel.com tools webfont-generator . This way your fonts will wait before the CSS has loaded before revealing themselves .", "Question : I am using the following JS to avoid a flash of unstyled content in a SEO-friendly way : .. . .. .

Your help is appreciated Comment : This code would need to be placed immediately after the Container element to be effective however it may not completely get rid of the FOUC . the only ways to 100 get rid of it is to either pre-style the elements add classes directly rather than with js or to hide them with inline css . Comment : What browser do you see this in I thought this was pretty much relegated to ancient versions of IE and that as long as your CSS links are where they should be in the head then this isn t an issue in today s browsers . Actually I d argue it was never an issue...it s just how they worked Comment : Regardless of how new your OS Browser is a slow PC still often gets a FOUC . Comment : @KevinB true though I d then say that s just an argument for not worrying about it . It s just how some browsers work . Comment : That depends on what pre-style you are adding . What exactly is causing the FOUC are you adding classes to the html with javascript are images not loading fast enough .. . Answer : The best way to avoid a FOUC is to put all of your links to your CSS files in the head element . This way the styling rules will load before the content which will then be styled . This is both SEO and user friendly . Comment : One of the issues is that I am using the anythingslider.js https : css-tricks.com examples AnythingSlider demos.html script however it is quite often being rendered like this css-tricks.com examples AnythingSlider demos.html https : css-tricks.com examples AnythingSlider demos.html when nothing is cached . Comment : That second link above is what I am trying to avoid with this FOUC solution Comment : See that s a js issue . I don t see any seo problems with pre-styling that slider by adding appropriate classes to the images which would cause all but the first one to be hidden . Comment : Yea this isn t really an issue of CSS but that you have to wait for the JS to do all the styling . That s convenient for you as the developer but does introduce the FOUC . The prestyling is likely the best option here . Comment : That s a great idea @Kevin B .

It s located here : http : www.cmscritic.com Comment : I believe it s FOUC Comment : Flash of Unstyled Content FOUC Comment : This happens many a times if we have the link tag of style sheets referred at the bottom of the web page . .. . Answer : The problem with using a css style to initially hide some page elements and then using javascript to change the style back to visible after page load is that people who don t have javascript enabled will never get to see those elements . So it s a solution which does not degrade gracefully . A better way therefore is to use javascript to both initially hide as well as redisplay those elements after page load . Using jQuery we might be tempted to do something like this : .. . .. . However if your page is very big with a lot of elements then this code won t be applied soon enough the document body won t be ready soon enough and you might still see a FOUC . However there is one element that we CAN hide as soon as script is encountered in the head even before the document is ready : the HTML tag . So we could do something like this : .. . .. . Note that the jQuery addClass method is called outside of the .ready function . Comment : Great post This helped fix a problem I had to solve . Thank you Comment : To me it seems cleaner to replace html .show with html .removeClass hidden . This makes it clearer that the ready function is undoing the addClass . Comment : UPDATE : Just tested this approach . The current version of jQuery REQUIRES this to be done using removeClass as I suggest rather than show as in the original answer -- otherwise the html will NEVER show . I believe jQuery s show now explicitly looks for and restores any display state from css styling to avoid interfering with styling . Therefore it is necessary to actually remove the hidden class . Comment : Works perfectly . Opted for the removeClass option rather than show Comment : By far the best solution I have found .

Making it into the markup of such a popular website several times to boot due to conditional HTML classes http : www.paulirish.com 2008 conditional-stylesheets-vs-css-hacks-answer-neither being utilised must make it useful for something . I am familiar with the concept of flash of unstyled content aka FOUC but I m curious as to what this code relates to specifically . Comment : I noticed it is added only for IE8 in some sites . .. . Answer : If you look at line 38-40 you get .. . .. . Which changes the document element class to include the value set in this attribute . This allows the css to hide the Flash Of Unstyled Content as the page and javascripts load . Later the scripts remove this class to allow the fully loaded page to load . It also appears to be used in the ajax page loading code to allow content to load hidden and only displayed once all content is load . Attributes beginning with the name data- are part of the html 5 specification and represent private data . They are there to allow webpages to store information within a webpage that without breaking validation via the HTML5 Validators", "Question : There are two websites one live one under development .

The original live site has seamless page loads - it will load then update the content on the screen while keeping the background-image navigation etc on the page . The ported site development flashes completely white for a brief moment then all of the content appears simultaneously . From what I understand this is not a FOUC flash of unstyled content . The content on both of the sites always appears fully styles with all CSS rules . The two sites look identical when rendered they use the same images css and HTML markup . The only difference is one development is being served by Zend Framework and the other live by procedural PHP . What are the main causes for this and is this a known bug configuration issue with ZF I ve had this problem before without using ZF and did not resolve it . Thanks for your help . .. . Answer : It could be your web server . Try comparing the HTTP headers of your servers with a web sniffer like http : web-sniffer.net and see if there s any difference in caching headers . If there is then your browser is dumping everything and starting fresh which could look almost like a FOUC in some circumstances . Comment : Tried changing all headers to match for example staples.com s configuration . Still having a white flash between pages . Worth mentioning it s valid XHTML with no @imports for CSS", "Question : There are two websites one live one under development .

Answer : Try putting javascript at the bottom of the page just before the closing body tag . This should speed up page rendering as loading javascript blocks other downloads css images etc . therefore leaving your page blank until all of your scripts have loaded .", "Question : I have observed that very infrequently Internet Explorer 7 or 8 it does not matter displays our web pages www.epsitec.ch http : www.epsitec.ch products compta a short time without applying the CSS . The layout appears completely broken with everything displayed sequentially from top to bottom . When the page has finished loading everything finally gets displayed properly . Our web pages do not use any fancy scripting just two javascript inclusions for QuantCast and Google Analytics done at the end of the page . By the way we already had the issue before adding the QuantCast script . The CSS gets linked in the head section : .. . .. . and then follows static HTML up to the final chunk which includes the JavaScript : .. . .. . As this is a very short visual-glitch I have no idea what provokes it . Worse I cannot reproduce it and it appears only on seldom occasions . How can I further investigate the cause of the glitch Are there any best practices I should be aware of .. . Answer : FOUC has to do with the order of loading external assets like CSS and JS files . Inline script snippets block downloading of subsequent assets until they are interpreted . This is one of the causes for FOUC . A best-practice for front-end performance as well as avoiding FOUC is to have your CSS files referenced in the head of your document and your JavaScript right before the closing body tag . This makes the browser download styles render the page then apply JavaScript .", "Question : I am getting FOUC when loading css inside of my entry-point when using webpack . If I remove my css from being loaded by webpack and just include it in my html file as a normal link then the problem with FOUC goes away . Note : This not just with bootstrap framework I have tested with Foundation and Materialize with the same results .. . .. . The code posted below is just a test example of my problem using Bootstrap . Html code .. . .. . bootstrap.js main entry-point .. . .. . webpack.config.js .. . Answer : ExtractTextWebpackPlugin https : github.com webpack extract-text-webpack-plugin will allow you to output your CSS as a separate file rather than having it embedded in your JS bundle . You can then include this file in your HTML which as you said prevents the flash of unstyled content . I d recommend only using this in production environments as it stops hot-loading from working and makes your compile take longer . I have my webpack.config.js set up to only apply the plugin when process.env.NODE ENV production you still get the FOUC when you re doing a development build running the dev server but I feel like this is a fair trade off . For more information on how to set this up take a look at SurviveJS s guide http : survivejs.com webpack building-with-webpack separating-css .", "Question : I m using Head.js Google Web Fonts and pulling some content from elsewhere on the web placeholder images . What I ve noticed is that on page load I see unstyled content then my heading font loads properly but not at the proper weight and then the proper weight loads . Any idea as to what is causing this odd behaviour with my header text Should it not just go from unstyled to the proper requested font Also what is the best way to stop the FOUC thats friendly to people with javascript disabled Thanks Some more details : .. . .. . I m using Google s provided Javascript method to insert the 3 fonts I use . I can clearly see that it is loading Istok+Web : 700 : lating which means only the 700 weight should be provided . Because of this method I do not use @font-face at all . Simply font-family as-if it were a regular thing . I am using LESS.js though but from the network analyzer it doesn t seem to be causing any major slow down . .. . Answer : This is simply caused by the browser displaying the website already before it downloaded all content . Do you have one @font-face css rule for all font weights or do you have a seperate one for the normal bold font weight Please also note that although it is convenient to load the fonts from the Google CDN it is not the fastest way as a new http connection has to be established . EDIT when you use the quick-use button google does always set different font files for different weights.. . .. . .. . A flash of unstyled content cannot be prevented when using head.js as everything is loaded parallel while the browser tends to show everything it s got asap . Just pray everyone has a fast connection . And why should you mind at all During loading you always see some kind of a half page.. . Comment : the FOUC seems to be able to be prevented in theory by using visibility : hidden and then on head.ready set the visibility to visible . My issue with this solution is A i can t seem to get it working myself and B people with javascript disabled would see nothing . Comment : but people with javascript disabled will not see anything anyhow beacuse you load your assets with javascript.. . So if you want your site to be viewable with styles and javascript effects do not use head.js.. . Comment : they will see unstyled text . Which is fine . But if I were to implement a visibility : hidden they would see no text .", "Question : I need someone who can provide me with a solution that will stop the flash of unstyled content fouc on my site . It s located here : http : www.cmscritic.com Comment : I believe it s FOUC Comment : Flash of Unstyled Content FOUC Comment : This happens many a times if we have the link tag of style sheets referred at the bottom of the web page . .. . Answer : A solution which doesn t depend on jQuery which will work on all current browsers and do nothing on old browsers include the following in your head tag or you could put it at the start of the body : Comment : NOTE : To avoid the flash this should all be inside head tag similar to Stefan s answer . Or at least at the start of the body . I mean if the script is placed at the end of the body it might not run until after the content has already appeared .

I must have either typo d it here or subsequently found and fixed the mistake . Probably the latter because I would surely have copy pasted .", "Question : The static html pages of my project has javascript dynamically modified content and that causes FOUC Flicker of Unstyled Content . So I made the content invisible by default and toggle display to visible after DOM ready . The static html pages rendered very fast on my local drive so the time gap between invisible and visible states is not obvious . However after the project has been integrated with WordPress and put onto remote-server the page rendering becomes a bit slower so the time gap becomes a bit more obvious . When I click on a hyperlink to request viewing a page I would like WordPress to complete the redering of the page on server-side and then show me the page . Waiting 1 or 2 seconds is okay . Can WP do that Comment : Have you considered using a caching plugin instead That would probably be the better option Comment : @Pekka I m a front-end developer so I actually know very little about WP . Can that plugin do the job Comment : It doesn t do the job you re asking for but it creates static files that will be served very fast Comment : Thanks . I will investigate more of it . Comment : WP super cache is the household name to look at .. . Answer : I would guess that the issue is your CSS not loading instantly over the network so that there s a moment where your HTML is rendered but your CSS hasn t loaded . It could also be dynamic Javascript content -- I can t speak to that without knowing more about your Wordpress installation and configuration .. . .. . Preloading your CSS isn t something Wordpress can do itself although you should notice that after the first page load the browser is caching your CSS and it s quicker . If you re really concerned about it look up some optimization techniques such as using a fast CDN for the static stuff such as your CSS . The Yahoo performance tips http : developer.yahoo.com performance rules.html cdn are pretty good for all website performance questions for instance . Comment : Thanks @necaris . My issue is dynamically javascript added className etc causes the FOUC . That script can be executed only after DOM ready . Comment : @ian that sounds like a conceptual problem that will always cause some amount of fouc . Is there no way for you to hard-code the class Comment : @Pekka but on my local drive static html pages are rendered very fast and FOUC is not obvious . Comment : @ian yeah but that s local.. . On the net you have to anticipate occasional hiccups and latency Comment : @Pekka I just uploaded all static html pages files which haven t been made into WP to the remote-server for testing . And their rendering speeds are as fast as they are in local .

Is there something I can do to prevent this e.g . hide the images until the carosel has been initialised The FOUC is particularly bad in IE but also occurs in Firefox . .. . Answer : If you disable javascript on your browser you ll be able to see what the flash looks like . It s a good idea to make sure a page is at least always useable with JS disabled . Adding this css to your carousel will do the trick :", "Question : I have an AngularJS project I want to prevent a FOUC during page load on a classname .

Comment : Still seems to need ng-cloak along with that", "Question : null .. . Answer : FOUC http : en.wikipedia.org wiki Flash of unstyled content is a common user-experience problem for sites with a lot of CSS especially after you start combining your CSS files and the common solution is to separate important layout rules in a small standalone file which is loaded first . That leads to code which is hard to read and maintain because related rules are at very distant places . I am wondering if there is any CSS preprocessor which supports separating code into different files That is you would write something like .. . .. . and .main-content and .main-content h1 end up in different files . Or maybe the same on a per-rule level . Comment : The article seems to be somewhat incorrect . Please read bluerobot.com web css fouc.asp http : www.bluerobot.com web css fouc.asp for some very easy fixes . Comment : The bluerobot article defines FOUC very narrowly it can be caused by a lot of other things than @import ing . For example Safari has a different FOUC bug http : www.webkit.org blog 66 the-fouc-problem . Large slowly loading CSS files can also cause FOUC maybe not as bad but still visible and there is no easy fix for that except separating the CSS .", "Question : I m working on a site https : www.bassnationaudio.com store that has a lot of Javascript and jQuery--as far as I can tell most of it is triggered to load after the document is ready . However when the page loads you get about a second of white FOUC . But if you disable Javascript completely there is no white flash at all . How can I make sure that the Javascript doesn t begin loading until after the page loads It is already liberally using .. . .. . .. . so Javascript shouldn t fire until the page is done loading and is rendered.. . right But somehow the page waits for the script to finish before rendering--even though it doesn t need to since the page still looks mostly fine with Javascript totally disabled . Comment : window .load function put script tags at bottom of page they are in header Comment : you get about a second of white FOUC No not from my location using Opera 12 and Chromium 23 . Comment : @feeela That s weird . I m using Chrome 24 but I wouldn t think that s the issue . What OS are you using Comment : @feeela - agreed about the worst I get is a delay of the font loading in FF 19.0 on Mac OSX . Comment : script tags do stop the processing of the page until they are done loading and executing . To reduce the impact of that simply move them to before the closing body tag . .. . Answer : The first thing I would try is reordering your script and style tags so that all external css files are included prior to any javascript files . I ran an audit using Chrome s developer tools and found 13 stylesheets that are included below a javascript file . Since browsers generally only allow 2 concurrent connections you could see this flash if the html gets loaded but a stylesheet download is getting queued behind some other resource . This would also explain why in the comments so many other people are having a difficult time reproducing what you re seeing -- they have different connection speeds and such .", "Question : I dynamically create multiple tabs using jQUery UI tabs -- the tabs are created using a foreach on a view page as follows some codeigniter markup : .. . .. . As above the tabs are formed fine . Problem is the good ol Flash Of Unstyled Content . It happens on IE Chrome FF . I ve tried the CSS option on the jQuery documentation didn t work .

Answer : You re disabling Roboelectric s HTTP layer so you re using the real HTTP layer . This means that there s no clever magic happening under the hood of your test : when you send an HTTP request it s really going out onto the internet as you are seeing . MockWebServer doesn t stop this . It just sets up a web server locally that your test can connect to .

Answer : Retrofit has a retrofit-mock module which offers a MockRestAdapter class whose purpose is to simulate network delay and errors . This is a used in conjunction with the normal RestAdapter to create an instance of your service .

Comment : I misread your question the first time . Does my answer solve your issue .. . Answer : The browser security warning you are getting is because of the host name mismatch in the url and in the server certificate e.g . localhost vs . example.com . To make the forwarding work without this warning you need to put the forwarder on the same TCP port and override DNS resolution for the effected domain i.e . make example.com resolve to 127.0.0.1 . The simplest approach is as follows : .. . .. . 1 . edit your hosts-file https : en.wikipedia.org wiki Hosts file and add example.com domain to the localhost line sort of howto is here http : www.howtogeek.com howto 27350 beginner-geek-how-to-edit-your-hosts-file .. . .. . 2 . start your forwarding beware that you need to use server IP address and not domain-name as the domain-name is already redirected to localhost .. . .. . socat TCP-LISTEN : 443 fork reuseaddr TCP : 123.456.789.12 : 443 .. . .. . 3 . check it is working in the browser via https : example.com .. . .. . Do not forget to remove the domain entry from the hosts-file when done experimenting . .. . .. . If you can t ensure the same TCP port-number this approach might work as well -- but only under some conditions : .. . .. . the site is using relative paths in links as an absolute path would use original thus different port-number .. . .. . there is no port-number written in the server certificate which is usually not the case .. . .. . .. . .. . Note : It is possible to setup a MITM socat proxy but this would require adding an artificial trusted CA . Good luck", "Question : I was looking for an answer on my question on google and also here but a didn t find a proper answer . So here is the context : I have a software running on some server without firewall in one subnet . There is another software running on some PC in a different subnet . Both subnets are connected to a gateway server . All computers are running CentOS or RHEL . On the gateway server there is a firewall preventing multicast traffic from leaving the one subnet and allow clients from outside to connect to computers inside this subnet . Therefore xinetd is used . The computer from outside needs to send a packet to a specific port the computer on the inside answers to another specific port depending on the sender . So there is no need for the gateway to keep track of sender-receiver relations . It just needs to forward UDP on specific ports to specific computers from one subnet to another . So I added one service in etc services for one direction : .. . .. . And created the according configuration file in etc xinetd.d gateway like : .. . .. . Now the problem is that the server doesn t open an UDP-port to listen on netstat -nulp says . When I change the protocol to TCP and the socket type to stream it works . But I need this for UDP . Is it possible that this is not possible for UDP Or is netstat just not showing the ports Or is my xinetd-configuration missing something Thanks in advance every hint is appreciated . Benny .. .

Answer : I finally found the answer at least for my situation The problem was SELinux . I turned off SELinux and it worked with no problem .

When user types http : secure.example.com it needs to be forwarded to https : secure.example.com . Is there a domain level redirecting forwarding requests coming through http to https in Amazon Route53 .. . Answer : No there is no way to do this -- because it s not a DNS function to force any particular protocol or to push values from one protocol to another . You can do this easily enough at the web server level either in Apache or IIS or NGINX . In any of those cases the A or CNAME value pointing a specific record to a specific address whether an IP or another host name is the same it s just going to connect via port 80 or port 443 .

The entire experiment is comprised of 120 trials so rather than building the question 120 times I am trying to use Qualtrics Loop function to loop the questions .

L0 high 1 for the first question and then L9 low 2 for the second question and so on . I am aware that we can use Qualtrics Piped Text function to dynamically change the numbers in the Source code .

Answer : It is not clear what you are asking . By NSZombies do you mean setting the NSZombies flag to true in your project Yes that will cause your program s memory to grow forever and you will eventually run out-of-memory and crash . When zombies are enabled instead of releasing objects on dealloc the runtime marks them as zombies and leaves their memory in use . If you mean can having zombies in your program objects that get deallocated but your code tries to send messages to them then yes that can and often does cause crashes . Zombies are less common under ARC but still possible . Comment : Yes I mean t If you mean can having zombies in your program objects that get deallocated but your code tries to send messages to them . But the root cause of the crash wouldn t be because NSZombies were enabled right Meaning turning off NSZombies would not have prevented the crash .

Store the array with the operation object so you know it won t be released on you . It s a few extra lines-of-code compared to detachNewThreadSelector but it s much safer .

People have said it can cause a crash by a bug where dealloc is not called on the object . That is not the case .

Answer : Omega you should be careful with ownership : .. . .. . You should synthesize retained setter for selectedItem .. . .. . .. . .. . .. . Then using setter assignement . Not plain pointer assignment . Comment : your answer is incorrect . both selectedItem and currentItem are retained in an array when that routine executes . The only reason i can see for this is that @Omega removed the selectedItem as child of the CCMenu somehow without overriding the removeChild methods of CCMenu in order to set the assigned iVars to nil after removal from the array . Comment : Yves my solution is incorrect i didn t see it was inside CCmenu . But the design of CCMenu still relies on ownership GUI . Yes this is not what make the app actually crashing but the consequence of client implementation . By the way you should admit that the usage of selectedItem relies on lot of GUI logic stuff . You said it selectedItem as been popped of the child hierarchy and that s what make selectedItem dangling . The fact is SelectedItem should not be dangling that should never happen . Even if the client of that code is not doing what is expected that should not crash this way Comment : By the way great game this Max Power Adventures . I m a big fan Comment : New one in the works .. . old style funny and will have a PVP capability . Regarding selectedItem i agree with your diagnostic .

I am using Cocos2d v0.99.5 not to sure . Recently started to get into some problems when I started remove sprites . Have profiles using instruments and Zombies and here s what I get : .. . .. . Zombie trace http : i.stack.imgur.com g6OUq.png The code for updating the sprites and also delete them is located in update : .. . .. . The remove method in GameSprite.m : .. . .. . The first block updates the sprites in the SpriteBatchNode textureAtlas . The three remaining blocks checks the different objects if the should be deleted . their alive-variable set to NO . The reason I have three blocks of different types is due to the fact that projectiles have weak reference to creep they are shooting at and needs to be deleted before the creep . So my problem is that it randomly crashes when a projectile hits a creep and the projetile and all other projectiles shooting at that creep are to be removed . The creeps reference count gets down to 0 but seems to still be in the childs array . Cause the error I get is : .. . .. . on the row I marked with .. . .. . Either the problem is with me understanding Cocos2d s removeFromParentAndCleanUP : or that my solution for handling the projectile-creep-relationship is bad from a memory point of view . Any ideas on how to solve this or debug it further .. . Answer : Your fast-enumeration techniques for going through the array are casting all your sprites in that array as a custom subclass of CCSprite then checking to see if they are instead a different custom subclass like Tower etc . I don t see this as healthy programming practice since methods in one class may not be in the other yet you are casting them nonetheless . That may or may not be contributing to your issue but a wiser approach is to keep an assign iVar CCArray for children of a specific class . i.e . put all your projectiles into one array at the time they are created and added to the batch node then you can iterate through all projectiles towers etc by going through those individual arrays where you know what kind of class they already are . Then remove them from the array as well as from the parent when necessary . I would think this is quite a bit safer than going through all the game s sprites in their entirety that are in your batchnode which may include spites not being used perhaps and casting them and testing them as different classes . Comment : Thanks . Solved it by creating three new arrays and enumerating through them instead . Was hoping to skip this but it seems that iterating through the children of textureAtlas is not a safe way to do it . Comment : That s great to hear it worked out using the safer techniques .

Comment : Why don t you change id sender to NSButton sender in - IBAction countCharacters : That way you won t have to check . Unless this is not only called through the GUI . Comment : @zneak that doesn t make sense . An action method is always - IBAction selector : id sender . And whether or not you check is entirely orthogonal to how target action works . Comment : @bbum It does make sense . Explicitly telling what kind of object you expect to send the action makes it impossible in Interface Builder to assign the action to any other type of object . Which is obviously what he wants . I just double-checked in case I did say something utterly stupid and it behaves exactly the way I describe it . Comment : Yup . You are correct . My mistake . .. . Answer : It s because you do not own the objects you try to release you don t hold a reference to them . Their ownership is given to the nearest NSAutoreleasePool . You can read about object ownership here http : developer.apple.com mac library documentation Cocoa Conceptual MemoryMgmt Articles mmObjectOwnership.html . As a quick reference usually you aren t the owner if you didn t call the alloc method yourself to create the object or if you didn t retain it . Retain ing an object makes you an owner calling release means you give up ownership and will deallocate the object if it has no more owners . You must not release objects for which you don t have ownership . Your current code without release is exactly what you need . Comment : Exactly correct . In other words if you were to uncomment the commented lines then run Zombies the zombie logging mechanism would trigger . Comment : thank you that makes sense . i knew i shouldn t release them but it didn t click as to why not .

Answer : I have a situation where I have copied a string in an instance of a helper class retained it and later released it during the dealloc of the view controller instance that alloc d the helper class . This results in the dreaded EXC BAD ACCESS . I then went to Instruments to debug zombies . This gave me the following error : .. . .. . An Objective-C message was sent to a deallocated CFString immutable object zombie at address : blah blah .. . .. . When I then look at the allocation summary within Instruments and work backwards from the zombie detection the first time my code is listed is in the deallocation of the helper class instance . Here is what the helper class looks like . First the .h file : .. . .. . Then the .m file : .. . .. . Now relevant code from the view controller that uses the helper class looks like the following . In the .h file I have an array that will hold multiple objects of the helper class as follows : .. . .. . Then in the .m code I synthesize channelTitles . I also have a dealloc method as follows : .. . .. . Finally I alloc object instances of the helper class and store them in channelTitles with strings stored in the channelTitle elements of channelButtonTitles as follows : .. . .. . So this is a technique I have used many times before but seems to not be happy now . When the view controller is popped and I return to the root view controller the dealloc method in my view controller is called . That releases channelTitles which results in calling dealloc on the channelButtonTitles helper class objects that are stored in channelTitles . Since I have used copy in the property of my helper class I assume I own this string . Hence I am releasing it . If I comment out the channelTitle release line from my dealloc the EXC BAD ACCESS goes away but I suspect I have a memory leak now . Please help me see what I am doing wrong .

Have you ever converted a large software app to arc If so what was your experience Comment : @matt yes that was the first thing I tried . It did not see a problem with this . Comment : You need to look for places where you modify the channelTitle instance variable directly without going through the setter . One thing to try would be to refactor to rename that instance variable to channelTitle which will make it easier to find such places . Also make sure that nothing obtains the reference via the property getter and then releases it . For example NSString temp whatever.channelTitle .. . temp release . Or perhaps another class has an assign property that it releases in its -dealloc and it gets assigned from whatever.channelTitle .", "Question : I have a major issue that I am stuck with at work and would REALLY appreciate some help on . This has cost me 2 days already . What I am trying to do is have a special image class fire it s assigned callback when it s touched . Thats it . But when I touch the image it crashes often without an error message just lldb . Sometimes it says garbage like NSCFData tapped : : unrecognized-selector sent to instance 0x1780af360 . Sometimes it says message sent to deallocated object . I can run the app 10 times in a row and get one of these random messages just from tapping the same object on the screen each time . The code is very simple : .. . .. . And here is the code inside K PreviewImage my clickable image . This does NOT inherit from anything including NSObject .. . .. . The above code causes a crash 100 of the time . If I add @objc too the tap event-listener in the K PreviewImage like this .. . .. . Then the code WORKS and the touch-event is fired both inside K PreviewImage and the controllers callback function nestedTap . Not sure why that works but it does . However I m still up a creek without a paddle because when I make the K PreviewImage a function variable instead of a class member variable I get a crash again .. . .. . So my first question is why did I need to add @objc to get the callback to fire instead of giving me an unclear deallocated memory crash My second question is why is it when I moved the variable from a member variable to a function variable does it cause the crash all over again . If the object was deallocated it couldnt hear the tap event in the first place could it Why would it still be on screen And why is it getting dealloacted just because it s not a member variable How the heck can I create a custom object dynamically and have it fire click events UPDATE .. . .. . Here is the full code block involving how my K PreviewImage was being added with a touch-event .. . .. . Solved : .. . .. . Because I was not storing a reference to the K PreviewImage k even though the subview was added even though it belongs-to k k was not being retained . By making the array store a reference to K PreviewImage instead of iImage the compiler now retains a reference to the K Preview Image .. . Answer : First off it looks like you re trying to add an image as a subview . I don t know Swift all that well but view.addSubview k.image looks wrong to me and would make more sense as view.addSubview k . Secondly you re not keeping your reference to your K PreviewImage . You are assigning k.image as the subview which causes k to be detected as no longer used by the system . It will clean it up and when you try to access it you ll crash . Comment : First off thanks for taking the time to review this and give a thoughtful response . Regarding the system detecting K as no longer user why is that I am storing K inside of an array which is a member variable . By adding I.image why does the system remove the parent and keep the child image is a member variable of K It wasnt shown in this example but I do store K in an array after adding it to the view with array.append K Comment : Can you update your source to reflect the correct scope of k Because you re getting an error that states NSCFData tapped : is trying to be accessed it looks a lot like the object you re expecting is not the object you have -- indicating that the memory was released back to the system and an NSData object appeared in its place . Comment : Brilliant thanks to you I figured it out . I was storing the iImage class in the array reference but that apparently does NOT retain the object that is a part of i.e . the K PreviewImage but making the array and array of K PreviewImages the variable is retained properly now .

Which you obviously don t have available in a 64-bit version or on this new install of Windows . .. . Answer : VfW works in x64 machines but only if your process is x86 . An x64 process will only be able to open x64 codecs . x64 codecs do exist but they are rare and need to be installed . If your process has to be x64 and you have to access x86 codecs then the only way to do it is to have a multiprocess architecture with a child-process doing the file read and passing the data to the x64 parent via named-pipes .", "Question : Does the VFW Video For Windows API support Alpha Channel Transparency I want to be able to export video with Alpha channel information .

Not exactly about the same + - . Also I can record the signal from that cam using internal Windows recorder and I can see like signal level jumps up and down on my voice up and down so the mic of the webcam is Ok also. . I suppose that might be something wrong with VFW input audio signal feeder . Even it accepted the WAVEFORMATEX and sent back WAVEHDR they re both ok.. . but the buffer data is populated with some other source not the webcam though VFW says it must be from Webcam cause video is capturing from the same source and it s working I just added one extramessage : SendMessage camHwnd WM CAP SET CALLBACK WAVESTREAM 0 audioCallback I m pretty much sure if I ll use waveIn instead of VFW it will work ok. . I ll check it later on. . But why the VFW works not like it supposed to Comment : It s possibly a feedback loop . Also given that you are recording from the web and feeding a D A converter and both are not necessarily running at the same rate how do you know you are not having buffer overruns or underruns Comment : Pls see the additional UPD .. . Answer : The problem was very simple - that was USB hardware failure . I needed to unplug USB Camera and plug in again . But anyways I d like to share my knowledge about that . 1 We should use Asynchronous mechanizm of getting and sending packs of audio data to the playback end . Until the first buffer has played back we have to avoid sending new buffer to playback . The method is called - double or even tripple buffering . And with VFW you can organize it very comfortable using WM CAP GET SEQUENCE SETUP message and CAPTUREPARAMS structure . The wNumAudioRequested parameter is used to setup how many different buffers will be cyclically used to send audiodata to your audioCallback . It s set to 10 by default more than enough . 2 The best way to check out if your audio signal is the valid signal is : in your WAVESTREAM Callback do Marshaling of bytes from received buffer with audiodata into managed static array of bytes . Then inside the callback do output of 50-100 sample values with Console.Write array i + and see if the values re changing on your voice up and down . Take into account that the Zero level is at the middle of WAVEFORMATEX- wBitsPerSample value and in my case 8 bits sample the values are 125 126 127 128 129 . It s accepted as silence and no signal or Zero-noise . Once you sure you have correct audiodata now you can go further to your goal . 3 Remember when you re on recording from mic mode the local output wave device better to be closed . Your goal is to collect audio data to record or send through Network . Do not try getting data and waveOuit them locally . Sometimes latency value of your speaker is bit higher than speed of sampling mic data and you ll get messy with buffers as it took place with me . Then I just followed the principle - recording is when you collect save or send audiodata and it should be played back after recording or at the same time but on the endpoint PC . 4 To be continued with code", "Question : I need to get a regular snapshot from a webcam in Delphi .

And also it does not display the whole available image you d have to enlarge your Panel recenter or shrink the webcam output . Update with some code modifications that would make it work per your comments.. . Comment : On my system the message results I get are : WM CAP DRIVER CONNECTMsgResult false WM CAP SET PREVIEWRATEMsgResult true WM CAP SET OVERLAYMsgResult false WM CAP SET PREVIEWMsgResult false WM CAP SET CALLBACK FRAMEMsgResult true WM CAP GRAB FRAME NOSTOPMsgResult false and FrameCallbackFunction never fires . It looks as-if it is failing to connect . Comment : Clearly you cannot connect to the webcam . Have you tried with a capture driver other than 0 It can be from 0 to 9 . Maybe you have more than 1 and the webcam is not the index 0 MsgResult : SendMessage FCapHandle WM CAP DRIVER CONNECT x 0 Comment : Thanks Fran ois . At present I don t have any webcams - just a simulator . The simulator seems to go in that Skype can see the camera OK . I tried calling SendMessage FCapHandle WM CAP DRIVER CONNECT x 0 with x 0 through 9 and they all returned false . Incidentally - how were you able to format the text as code in the comment Comment : Update - I installed a real webcam . Now when I execute the SendMessage FCapHandle WM CAP DRIVER CONNECT 0 0 a dialog pops up asking me to select the video capture source . The drop-down only has one entry in it - for the Logitech webcam . When I select this however I still get the same failure result false from SendMessage FCapHandle WM CAP DRIVER CONNECT 0 0 . Comment : Hey Fran ois I am tantalizingly close . With a real webcam connected I can get 1 second snapshots displaying on the panel . Problem is I need programmatic access to the image . The JPEG file saved is all black . I have tried several other variants of the example code off the web and they all work but the jpeg is blank . Any ideas", "Question : I need to get a regular snapshot from a webcam in Delphi . Speed is not a problem once a second is fine .

Answer : Graph before and after clustering nodes R 1 and R 2 http : i.stack.imgur.com ORbC9.png .. . .. . In the picture linked above I have a graph with nodes R1 through R5 and vertices linking them . All the vertices are weighted 10 in this case and a node can have any number of vertices attached to it the vertices can have any positive integer weight . I want to essentially condense this graph down to one node by combining all the nodes . The computational cost of combining two nodes in the context of the program I m running these nodes actually represent operations on arrays but it is not necessary to understand that to look at the problem I m positing here is the weights of all the edges included when combining any number of nodes . For example in the picture the cost of combining nodes R1 and R2 is 10 10 10 2 since there is one edge between them and node R2 also has a second separate edge . The cost of combining all the nodes in the graph at once would be 10 10 10 10 10 10 5 since there are five edges all weighted 10 in the entire graph . However by combining two nodes at a time in a strategic order it is possible to reduce the cost to the order of 10 3 . I want to write an algorithm that will help me combine nodes in an efficient manner I ve tried writing a simple greedy algorithm as well as a recursive algorithm that finds every possible combination and returns the cheapest . Both algorithms work as intended but the recursive algorithm is prohibitively slow and the greedy algorithm doesn t do particularly well when compared to the minimum cost that the recursive algorithm finds . I have also tried reducing the run-time of the recursive algorithm through dynamic-programming but it appears that taking advantage of overlapping subproblems isn t really possible here due to the great variety of weights that the edges can have while overlapping subproblems occur occasionally they are too rare to be worth taking advantage of . I am hoping that I can write an optimization algorithm that will give me results much closer to the actual minimum .. . .. . I am not terribly well-versed in graph-theory or combinatorics though I did make an attempt to search through graph-theory questions here and on the Internet before posting so I am posting here in the hope that this might be a known problem or similar to a known problem that I can take advantage of or that anyone might have other advice for working on this .

I am trying to come up with a ruby algorithm to find a best shortest-path within a defined limit sum of edges with the highest value sum of vertices . The start point will also be the ending point . for e.g . finding a path with a maximum of 20 with the highest total value . This problem seems like a np hard problem and it is hard to find the best solution . Is there a modified algorithm of dijkstra I tried using a greedy algorithm but it did not give me a optimal solution . and by using bruteforce on all poosible path will work but it will take very long if the number of nodes increases . Was wondering if there is any combination of algorithms that i can use to improve my solution Thanks . Comment : I don t understand first you say : I am trying to come up with a ruby algorithm to find a best shortest-path within a defined limit sum of edges with the highest value sum of vertices but then you say : finding a path with a maximum of 20 with the highest total value . In the second statement seems like you don t care about the path is the shortest . So do you want the path with the highest value max sum of vertices that compliant the limit sum of edges Is the meaning of best shortest-path what I say above .. . Answer : The problem is actually NP hard you can prove this doing a reduction of Hamiltonian path problem https : en.wikipedia.org wiki Hamiltonian path problem to this problem . Basically given an input for the Hamiltonian path problem we can stay with the undirected graph you can create an input for the problem you describe if follow this steps : .. . .. . build a new graph .. . .. . create a new graph that is the same that receive the Hamiltonian path problem but give to each vertex and edge weight 1 . create an input for your problem .. . .. . Pass to your problem the graph just created in the previous step and limit equals to infinity . Notice now that the result given by your problem is a path as longest as posible with respect at the number of vertex since the limit restriction is an upper bound in the sum of weight of the edges . This mean that you can add as vertex as posible and still complaint the limit restriction . How many vertex are in the path determine the total value of this count of vertex in the path since the weight is 1 for all of them . So the resulting path is the longest posible in the graph . With this insight we can verify if this path is a hamiltonian path just check the length of the path . If the path is of length N where N is the number of nodes in the graph there is a hamiltonian path otherwise there isn t . To solve the problem you can use an approach similar to Bellman-Ford https : en.wikipedia.org wiki Bellman E2 80 93Ford algorithm with some modifications . First create a matrix A i j where you storage all the highest total value paths that ends-with j and has length number of edges i . This is the key you can t just storage one of this path because in the next step you need to check all of them to make a relax here is where the implementation become non-polynomial . The relax technique in the step i iterate through all the storage path in A i-1 u and try to improve the value in A i v saving the new paths that actually do it you must check for when try to improve A i v in order to get all the paths of course this relax take into account the limit restriction . If you uses a global max and a global path and update it in each relax process you end with the highest value path for the entire graph .", "Question : I have an undirected positive-edge-weight graph V E for which I want a minimum-spanning-tree covering a subset k of vertices V the Steiner tree problem .

Comment : The question is unclear about whether k is a number or a set . Will you please clarify .. . Answer : The problem you stated is a famous NP-hard problem called Steiner tree in graphs https : en.wikipedia.org wiki Steiner tree problem Generalization of minimum Steiner tree . There are no known solutions in polynomial time and many believe no such solutions exist .

I m not limiting the size of the spanning tree to k vertices rather I know exactly which k vertices must be included in the MST . This problem is the Steiner tree problem .

But for the bipartite graph does the same approaches Comment : Yes it s possible using min cut Comment : @NiklasB . Could you describe the idea please .. . Answer : In any graph the complement of an independent set is a vertex cover http : en.wikipedia.org wiki Vertex cover and vice versa so your problem is equivalent to finding the minimum weight vertex cover in the graph . The latter can be solved using maximum flow techniques : .. . .. . Introduce a super-source S and a super-sink T . connect the nodes on the left side of the bipartite graph to S via edges that have their weight as capacity . Do the same thing for the right side and sink T . Assign infinite capacity to the edges of the original graph . Now find the minimum S-T cut in the constructed network . The value of the cut is the weight of the minimum vertex cover . To see why this is true think about the cut edges : They can t be the original edges because those have infinite capacity . If a left-side edge is cut this corresponds to taking the corresponding left-side node into the vertex cover . If we do not cut a left-side edge we need to cut all the right-side edges from adjacent vertices on the right side . Thus to actually reconstruct the vertex cover just collect all the vertices that are adjacent to cut edges or alternatively the left-side nodes not reachable from S and the right-side nodes reachable from S .

You can apply fuzzy-logic to that modelling to try to take into account the variablility in real life as not everyone gets lung cancer .

Comment : Hi could you solve your problem If possible can you help with the pseudo code code I have similar problem but the graph is unweighted . Comment : The question is unclear about whether k is a number or a set . Will you please clarify .. . Answer : I suggest you do the following : .. . .. . 1 . Create a copy of the graph . 2 .

The intuition is that we short-circuit the nodes which are connected through a vertex not in k . The cost of going via any such node v is the cost of going from the first node to v plus the cost of going from v to the second node . The MST in the resulting graph will be the minimum-spanning-tree covering the vertices in k in the original graph .

Comment : My best option for me was this : personal.kent.edu rmuhamma Algorithms MyAlgorithms GraphAlgor http : www.personal.kent.edu rmuhamma Algorithms MyAlgorithms GraphAlgor depthSearch.htm .. . Answer : There are two steps algorithms involved in finding all cycles in a DAG . The first step is to use Tarjan s algorithm to find the set of strongly connected-components . 1 . Start from any arbitrary vertex . 2 . DFS from that vertex . For each node x keep two numbers dfs index x and dfs lowval x . dfs index x stores when that node is visited while dfs lowval x min dfs low k where k is all the children of x that is not the directly parent of x in the dfs-spanning tree . 3 . All nodes with the same dfs lowval x are in the same strongly connected component . The second step is to find cycles paths within the connected-components . My suggestion is to use a modified version of Hierholzer s algorithm . The idea is : .. . .. . 1 . Choose any starting vertex v and follow a trail of edges from that vertex until you return to v . It is not possible to get stuck at any vertex other than v because the even degree of all vertices ensures that when the trail enters another vertex w there must be an unused edge leaving w . The tour formed in this way is a closed tour but may not cover all the vertices and edges of the initial graph . 2 . As long as there exists a vertex v that belongs-to the current tour but that has adjacent edges not part of the tour start another trail from v following unused edges until you return to v and join the tour formed in this way to the previous tour .

I want to find a connected subgraph that definitely includes a certain set of nodes and as few extras as possible . How could this be accomplished Just in case I ll restate the question using more precise language . Let G V E be an unweighted undirected connected graph . Let N be some subset of V . What s the best way to find the smallest connected subgraph G V E of G V E such that N is a subset of V Approximations are fine . .. . Answer : I can t think of an efficient algorithm to find the optimal solution but assuming that your input graph is dense the following might work well enough : .. . .. . 1 . Convert your input graph G V E to a weighted graph G N D where N is the subset of vertices you want to cover and D is distances path lengths between corresponding vertices in the original graph . This will collapse all vertices you don t need into edges . 2 . Compute the minimum-spanning-tree for G . 3 . Expand the minimum-spanning-tree by the following procedure : for every edge d in the minimum-spanning-tree take the corresponding path in graph G and add all vertices including endpoints on the path to the result set V and all edges in the path to the result set E . This algorithm is easy to trip up to give suboptimal solutions . Example case : equilateral triangle where there are vertices at the corners in midpoints of sides and in the middle of the triangle and edges along the sides and from the corners to the middle of the triangle . To cover the corners it s enough to pick the single middle point of the triangle but this algorithm might choose the sides . Nonetheless if the graph is dense it should work OK . Comment : Thanks I think this would work .", "Question : I would appreciate advice algorithms for the following problem : .. . .. . Consider a graph with V vertices connected by E edges V E 10 5 . When a vertex is removed all the edges connected to that vertex are removed . The vertices are labeled 1 2 .. . V . .. . .. . Input is given on E lines and on each line there are two space-separated vertex numbers representing an edge between those two vertices . The next V lines are a permutation of 1 2 .. . V representing the order in which the vertices are removed . Output V lines stating if the graph is connected i.e . there is a sequence of paths between every pair of vertices at each step . V and E are known and are given as space-separated integers on the first line of input . For example consider the following example input edges are undirected : .. . .. . 5 5 .. . .. . 1 2 .. . .. . 3 1 .. . .. . 2 3 .. . .. . 2 4 .. . .. . 5 4 .. . .. . 3 .. . .. . 4 .. . .. . 1 .. . .. . 2 .. . .. . 5 .. . .. . The first line indicates that there are 5 vertices and 5 edges . The next 5 lines describe the edges which are undirected i.e . an edge from 1 to 2 can also be taken from 2 to 1 . The 5 lines after that give the order in which the vertices are removed . For this example we would get the output as follows : .. . .. . When vertex 3 is removed the graph is connected since we can go from any of 1 2 4 5 to any other of 1 2 4 5 . When vertex 4 is removed the graph is disconnected because there are no connections out of vertex 5 . When vertex 1 is removed the same problem exists . When vertex 2 is removed only 5 is left so the graph is connected . When all vertices are removed the graph is connected . I tried a naive recursive approach as follows to check if it is possible to go from a start vertex to an end vertex : .. . .. . Checking at each step if it is possible to travel from all vertices A to all other vertices B using the above algorithm is far too slow O V 2 E V algorithm should be ideally O V log V or maybe O V 2 to run in about one second . .. . Answer : For each step store number of partition graph has . For initial graph it is done by doing full traversal DFS or BFS from initial vertex than repeat traversal from vertex that is not yet covered . If number of partitions is 1 than graph is connected . If removed vertex has degree 0 than number of partition is decreased by one . If removed vertex has degree 1 than number of partitions stays the same . If removed vertex has degree larger than 1 than number of partitions can be increased by max degree-1 . That is checked by similar traversing from neighbours of removed vertex . Start from initial neighbour and find all neighours that are connected to it . Repeat traversing from not visited neigbour . Comment : In the case where the degree of the removed vertex is greater than 1 can you go into more detail on how to find the change in number of partitions perhaps providing pseudocode I don t quite understand how the complexity of this solution has a smaller upper bound than E V for the DFS . Comment : Traverse all nodes connected to one neighbor . If all other neighbors are visited than removing vertex didn t split graph . If some neighbors were not visited than increase number of partitions by 1 and repeat process of traversing starting from some not visited neigbor . Note that if only one neighbor is left unvisited there is no need to make that last traversing starting from it .", "Question : I have been working on a graph implementation for the last few days . All of this is really new to me and I am stuck on two parts of my implementation . I am implementing a digraph of courses from an input file . From the file I can determine which courses are prereqs for other courses . I then create a digraph with courses as nodes and edges connecting courses that are prereqs . I also want to find the total number of nodes and edges and perform a topological-sort on the graph I will later be adding weights to the edges . Here is my implementation . Finding the number of nodes was easy just return work.size . I have confirmed this is working properly . I am lost on how I would return the number of edges in my graph . It seems it would be simple but everything I tried doesn t work . Secondly I am completely lost on how to perform a topological-sort on this graph . Any assistance is appreciated . Comment : Please note that Digraph : : addEdge can add a new edge from A to B even if there is already an edge . .. . Answer : First for the number of edges it would be simpler to count them directly when you build the graph just add a counter in your Digraph class and increment it each time you add an edge .. . .. . For the topological-sort first I have a question : your edges are from prereqs to dependant courses That is you have a link A - B if A is a prereq of B If this not the case you need to invert your graph . You to main algorithm in order to build a topological-sort : one based on a simple DFS http : en.wikipedia.org wiki Depth-first search and the other relying on in-degrees http : en.wikipedia.org wiki Directed graph Indegree and outdegree of your vertices courses in your case . Normally you need to verify that your graph doesn t contain any cycle which will normally be the case if your data are coherent . Let s consider the DFS based algorithm : a DFS traverses each vertices from a given root following edges as they appear . We can easily prove that order of last encounter of a vertex forms a reverse topological order . So all we need is to push in a stack the current vertex after the calls on its successors . I made a quick and dirty implementation for you using C++11 again . First add the following to the Digraph class : .. . .. . Then here comes the code : .. . .. . The code compiles but I haven t tested . If for any reasons you have an issue with the recursive algorithm the function Digraph : : dfs it can be derecursified using a stack containing the parent of the target vertex and the iterator to the current successor the iterator reach the end of the adjacency-list you can push the parent in the topological-sort . The other algorithm is almost as simple : for each vertices you need to count the number of predecessor in-degree which can be done while building the graph . In order to compute the topological-sort you look for the first vertex with a in-degree of 0 no predecessor you then decrease the in-degree of all its successors and continue with the next vertex with 0 . If the graph has no cycle there will always be a vertex with a in-degree of 0 at beginning of course but also during the algorithm run as you decrease it until all vertices have been seen . The order of vertices encounter form a topological-sort this is related to the Bellman shortest-path algorithm . Note that these 2 algorithms are listed here : http : en.wikipedia.org wiki Topological sorting . The one using in-degree is described in terms of removing edges which we simply simulate by decreasing the in-degree a far less destructive approach", "Question : Graph drawing algorithms such as those described here http : cs.brown.edu rt gdhandbook chapters force-directed.pdf check all the vertices two-by-two and apply additional forces if two vertices are connected by an edge .

Answer : I am going to assume that the question is : Given the degree of each vertex work out a graph that passes all the constraints given . I think you can reduce this to a very large integer-programming problem - linear constraints but with the variables required to be integers in fact either 0 or 1 which makes the problem much more difficult than ordinary linear-programming . Let the unknowns be of the form Xij where Xij is 1 if there is an edge from node i to node j and 0 otherwise . The requirements on the number of connections then amount to requirements of the form SUM all i Xij K for some K dependent on the requirement . The requirement that the graph is planar reduces to the requirement that the graph not contain two known graphs as subgraphs - https : en.wikipedia.org wiki Graph minor . Each possible subgraph then produces a constraint such as X01 + X02 + .. . 5 - there will be a huge number of these constraints - so large that for large number of nodes simply producing all the constraints may be too expensive to be practical let alone solving them . The number of constraints goes up as at least the 6th power of the number of nodes . However this is polynomial so theoretically practical to write down the MIP to be solved - so perhaps this is better than no algorithm at all .", "Question : I have an undirected positive-edge-weight graph V E for which I want a minimum-spanning-tree covering a subset k of vertices V the Steiner tree problem .

This is not the k-MST problem . The Steiner tree problem is defined as such : .. . .. . Given a weighted graph G V E a subset S V of the vertices and a root r V we want to find a minimum weight tree which connects all the vertices in S to r . 1 http : i.stack.imgur.com lQP8U.png .. . .. . As others have mentionned this problem is NP-hard . Therefore you can use an approximation algorithm . Early Simple Approximation Algorithms .. . .. . Two famous methods are Takahashi s method and Kruskal s method both of which have been extended improved by Rayward-Smith : .. . .. .

STAR : Steiner-tree approximation in relationship graphs . In ICDE 09 pages 868 879 2009", "Question : Say I have a directed acyclic graph with N vertices and a subset of the vertices at size M . .. . .. . The M vertices are all marked as visited how can I find all the vertices that all of their predecessors in the graph are visited .. . .. . for example : if there are 4 vertices a b c u and 3 edges a u b u c u and a b c are marked as visited I need to output u . I was thinking of going through all the vertices and for each vertex check all of his predecessors but I think that this isn t much efficient. . .. . Answer : Delete those M vertices from the original graph . This can be done by just removing the outgoing edges from the visited nodes . The nodes that are not in M and that are not reachable from any other vertex have all their predecessors visited in M . If the graph is of the form of an adjacency-matrix then this can be done by just scanning each column and checking whether there is any non-zero entry in it .", "Question : What does relaxation of an edge mean in the context of graph-theory I came across this while studying up on Dijkstra s algorithm for single-source shortest-path . .. . Answer : Relaxing an edge a concept you can find in other shortest-path algorithms as well is trying to lower the cost of getting to a vertex by using another vertex . You are calculating the distances from a beginning vertex say S to all the other vertices . At some point you have intermediate results -- current estimates . The relaxation is the process where you check for some vertices u and v : .. . .. . where est S a is the current estimate of the distance and dist a b is the distance between two vertices that are neighbors in the graph . What you are basically checking in the relaxation process is weather your current estimate from a to b could be improved by diverting the path through c this diversion would be the length of a path from a to c and from c to b .", "Question : If i have the following undirected graph with weighted vertices and edges : enter image description here http : i.stack.imgur.com 00ef1.jpg .. . .. . I am trying to come up with a ruby algorithm to find a best shortest-path within a defined limit sum of edges with the highest value sum of vertices . The start point will also be the ending point . for e.g . finding a path with a maximum of 20 with the highest total value . This problem seems like a np hard problem and it is hard to find the best solution . Is there a modified algorithm of dijkstra I tried using a greedy algorithm but it did not give me a optimal solution . and by using bruteforce on all poosible path will work but it will take very long if the number of nodes increases . Was wondering if there is any combination of algorithms that i can use to improve my solution Thanks . Comment : I don t understand first you say : I am trying to come up with a ruby algorithm to find a best shortest-path within a defined limit sum of edges with the highest value sum of vertices but then you say : finding a path with a maximum of 20 with the highest total value . In the second statement seems like you don t care about the path is the shortest . So do you want the path with the highest value max sum of vertices that compliant the limit sum of edges Is the meaning of best shortest-path what I say above .. . Answer : You can find an example of Djikstra s algorithm here https : github.com mburst dijkstras-algorithm blob master dijkstras.rb . What I would do is add a variable to count the number of vertices in the shortest-path and evaluate if the shortest-path has too many vertices or is too long once determining what the shortest-path even is .", "Question : How can I find iterate over ALL the cycles in a directed-graph from to a given node For example I want something like this : .. . .. . but not : B- C- B Comment : Homework I assume me.utexas.edu bard IP Handouts cycles.pdf http : www.me.utexas.edu bard IP Handouts cycles.pdf not that it s not a valid question : Comment : Note that this is at least NP Hard . Possibly PSPACE I d have to think about it but it s too early in the morning for complexity-theory B- Comment : If your input graph has v vertices and e edges then there are 2 e - v +1 -1 different cycles although not all might be simple cycles . That s quite a lot - you might not want to explicitly write all of them . Also since the output size is exponential the complexity of the algorithm cannot be polynomial . I think there is still no answer to this question . Comment : My best option for me was this : personal.kent.edu rmuhamma Algorithms MyAlgorithms GraphAlgor http : www.personal.kent.edu rmuhamma Algorithms MyAlgorithms GraphAlgor depthSearch.htm .. . Answer : Start at node X and check for all child nodes parent and child nodes are equivalent if undirected . Mark those child nodes as being children of X . From any such child node A mark it s children of being children of A X where X is marked as being 2 steps away . . If you later hit X and mark it as being a child of X that means X is in a 3 node cycle . Backtracking to it s parent is easy as-is the algorithm has no support for this so you d find whichever parent has X . Note : If graph is undirected or has any bidirectional edges this algorithm gets more complicated assuming you don t want to traverse the same edge twice for a cycle ." ] }

Comment : Thanks for the answer .", "Question : I m creating an Ionic application with a form and some required fields . When the form is submitted and if it isn t valid I display an alert message using Ionic s ionicPopup service . My problem is : the user can press ENTER or Go button within Android to both invoke form submission and close the popup which causes another popup to open . You can see this happening here : .. . .. . Sample Code http : play.ionic.io app cc24eac76ae1 .. . .. . Focus the input press ENTER and when the error message is displayed press ENTER again to close it . Another popup will open most likely because the input behind the backdrop still has focus or maybe because the modal is created within the form - having ENTER invoke submit again . Is there any way to avoid that behavior Maybe the ENTER within the ionicPopup to close it without submitting the form again or at least having some code to close any active popups before displaying a new one Because when you open multiple popups if you try the mouse or tap to close a message the user is prompted to then close all other dialogs before being sent back to the main screen .

Comment : you need to lose focus from the controls so when press enter will response to alert only Comment : I ve found out it doesn t work .

And I m struggling taking the focus out of the form because my page does not have any visible controls other than the form controls login page for example . .. . Answer : As it turns out my actual problem is that the ionicPopup does not support pressing ENTER or go on Android keyboard to close the popup . For some reason I tried to take the focus out of the inputs but it didn t work . For anyone with the same problem I ended up creating an angular-directive to close the device keyboard when the form is submitted . Here s the directive code : .. . .. . then I used it on the form tags like this : .. . .. . Obviously the problem still happens when testing directly on the browser but works when deploying to the devices . Comment : I think you don t need to use platform ready in the code . it will execute every time rather in your the app.js once you include that keyboard instance you can use that throughout and you can check if keyboard is shown then hide . Also we can use single vairable for multiple instance of popups hide the first intance and open other by assigning new one .

Comment : c traps and pitfalls is over 20 years old - do you really need to be backward compatible with stuff that was old 20 years ago Comment : Even if the book is 20 years old those rules still stand . .. . Answer : The library buffers input and output operations . Check out setvbuf and the IOFBF IOLBF parameters to that funktion . fseek or fflush require the library to commit buffered operations . The standard specifies a seek or flush operation as mandatory to allow the library some shortcuts otherwise for every I O operation the lib would have to check if the previous operation was also a read op or a write op and trigger a flush by itself if the direction of the I O changed .", "Question : Is using fseek to backtrack character fscanf operations reliable Like for example if I have just fscanf-ed 10 characters but I would like to backtrack the 10 chars can I just fseek infile -10 SEEK CUR For most situations it works but I seem to have problems with the character M . Apparently fseek registers it as a char but fscanf doesn t register it thus in my previous example a 10 char block containing a M would require fseek infile -11 SEEK CUR instead . fseek infile -10 SEEK CUR would make bring it short by 1 character . Why is this so Edit : I was using fopen in text mode .. . Answer : You re seeing the difference between a text and a binary file . When a file is opened in text mode no b in the fopen second argument the stdio library may indeed must interpret the contents of the file according to the operating-system s conventions for text-files . For example in Windows a line ends-with r n and this gets translated to a single n by stdio since that is the C convention . When writing to a text file a single n gets output as r n . This makes it easier to write portable C programs that handle text-files . Some details become complicated however and fseeking is one of them . Because of this the C standard only defines fseek in text-files in a few cases : to the very beginning to the very end to the current position and to a previous position that has been retrieved with ftell . In other words you can t compute a location to seek to for text-files . Or you can but you have to take care of the all the platform-specific details yourself . Alternatively you can use binary files and do the line-ending transformations yourself . Again portability suffers . In your case if you just want to go back to where you last did fscancf the easiest would be to use ftell just before you fscanf .

Looks like I read it wrong though it s only when alternating between input and output . Comment : @Wyatt8740 : that s fair enough and that s my experience as well .

One reason is that C runs on very diverse systems and with diverse media devices such as tapes may well need to be handled somewhat differently from the disk drive you re accustomed to thinking of .

The link recommends using fstat instead . Can anyone comment on this .. . Answer : The reason to not use fstat is that fstat is POSIX but fopen ftell and fseek are part of the C Standard . There may be a system that implements the C Standard but not POSIX . On such a system fstat would not work at all . Comment : The point of the CERT advisory is that on such a system the seek tell approach might have implementation-defined or undefined-behavior . However on such a system you don t have fstat .

Answer : The whole purpose of a buffered I O library is to free you from such concerns . If you have to read every 30th byte the OS is going to wind up reading the whole file because the OS reads in larger chunks . Here are your options from highest performance to lowest performance : .. . .. . If you have a large address space i.e . you re running a 64-bit OS on 64-bit hardware then using memory-mapped IO mmap on POSIX systems will save you the cost of having the OS copy data from kernel space to user space . This savings could be significant . As shown by the detailed notes below and thanks to Steve Jessop for the benchmark if you care about I O performance you should download Phong Vo s sfio library http : www2.research.att.com gsf download ref sfio sfio.html from the AT T Advanced Software Technology group . It is safer better designed and faster than C s standard I O library . On programs that use fseek a lot it is dramatically faster : up to seven times faster on a simple microbenchmark . Just relax and use fseek and fgetc which are designed and implemented exactly to solve your problem . If you take this problem seriously you should measure all three alternatives . Steve Jessop and I showed that using fseek is slower and if you are using the GNU C library fseek is a lot slower . You should measure mmap it may be the fastest of all . .. . .. .

Of course if you re stuck with NTFS or HFS+ it s just going to be slow . Shocking results just in .. . .. . I repeated Steve Jessop s measurements on Linux . The GNU C library makes a system call at every fseek . Unless POSIX requires this for some reason it s insane . I could chew up a bunch of ones and zeroes and puke a better buffered I O library than that . Anyway costs go up by about a factor of 20 much of which is spent in the kernel . If you use fgetc instead of fread to read single bytes you can save about 20 on small benchmarks . Less shocking results with a decent I O library .. . .. .

Using a sensible I O library fseek is more expensive but not more expensive enough to make a big difference 4 seconds if all you do is the I O . The GNU project does not provide a sensible I O library . As is too often the case the GNU software sucks . Conclusion : if you want fast I O your first move should be to replace the GNU I O library with the AT T sfio library . Other effects are likely to be small by comparison . Comment : Prepare to be shocked fseek causes a big slowdown on my machine NTFS Windows XP cygwin . Comment : @Steve : cool Compared with what Comment : @Steve : I m pretty skeptical about cygwin . I d love to know how performance compares with the Microsoft C compiler and library identical code . Comment : I could chew up a bunch of ones and zeroes and puke a better buffered I O library than that . It s open-source . Re-write it yourself and submit it if it gets rejected for some big reason e.g . POSIX requires it then you ll know why the GNU library performs so badly .

Answer : First and foremost you should be checking for the success of fopen as-if it fails passing the returned pointer NULL will invoke undefined behaviour https : en.wikipedia.org wiki Undefined behavior in fseek . You should not be using the returned pointer any further if fopen failed . That said to detect the error in fseek itself you should be checking the return-value of fseek for success or error . In case fseek is failure it will set the errno variable . You can check the same against the EBADF . You don t need any utility as such to check the error-code .

The program successfully compares the first word and gives me a result but I just can t get the fseek to move correctly to the next line This is the current version of the part that seeks for words . .. . .. . fileCount is set to 0 and strlen should return the length of the string srtFile but it doesn t quite well . I even tried setting fseek manually but it just wouldn t move . The words from my file are : First Last Index Field ID Number Fire Film . each is in a new line . When I run the program and type in F to search for a word that has a capital f the output is : .. . .. . I am desperate . Any ideas clues EDIT A big thank to everyone who helped me with this Comment : Don t you want to increase fileCount If you re in Windows you might want to open with rb because of the CRLF convention . If you re reading through the file sequentially why bother with fseek at all Comment : Your filepointer is already at the next word fgets moves the file-pointer as it reads so the fseek is superfluous . Comment : BTW fseek may be dangerous for files opened in text mode explained here http : arstechnica.com civis viewtopic.php t 420490 . Summary : because of n - r n conversion the parameter to fseek should either be 0 or come from an earlier ftell call . So you should use both fseek and ftell in your program or none Maybe you don t need fseek at all . Comment : calls to the system functions fopen fseek fgets when used in code should have have the returned value checked to assure not error occurs and or to enable the code to recognize an error event and have a chance to fix it . Comment : in the posted code there is absolutely no need for the call to fseek as the call will step the file-pointer which after the call to fgets is already moved forward the amount of characters read by fgets .. . Answer : Your problem is that you are not using fseek correctly . In your code .. . .. . sets the pointer to where its current at plus the filecount the offset . That s why it skipped Last and reads Index as string 2 . To fix this simply remove the fseek statement .", "Question : Is using fseek to backtrack character fscanf operations reliable Like for example if I have just fscanf-ed 10 characters but I would like to backtrack the 10 chars can I just fseek infile -10 SEEK CUR For most situations it works but I seem to have problems with the character M . Apparently fseek registers it as a char but fscanf doesn t register it thus in my previous example a 10 char block containing a M would require fseek infile -11 SEEK CUR instead . fseek infile -10 SEEK CUR would make bring it short by 1 character . Why is this so Edit : I was using fopen in text mode .. . Answer : Fseek has no understanding of the file s contents and just moves the filepointer 10 characters back . fscanf depending on the OS may interpret newlines differently it may even be so that fscanf will insert the M if you re on DOS and the M does not appear in the file . Check your manual that came with your C compiler", "Question : I have a question about the fseek usage in C . I know it can set the offset position of a file-descriptor created by fopen . But can it also set the offset position of a newly created file To be more specific can I : .. . .. . Will it create a file with 1 GB size and no content Or should I at least write something in order to create this 1 GB file Comment : I am reasonably certain that there will be content it will just be random content as in what ever happens to be in the disk area allocated . You may want to initialize the data area to some known value . Comment : However pubs.opengroup.org onlinepubs 009695399 functions fseek.html http : pubs.opengroup.org onlinepubs 009695399 functions fseek.html says that The fseek function shall allow the file-position indicator to be set beyond the end of existing data in the file . If data is later written at this point subsequent reads of data in the gap shall return bytes with the value 0 until data is actually written into the gap . however what happens if you close the file then open it again Would it still remember Comment : The seek will just move the position but will not extend the file unless you write something at that position . Comment : As @MarioZannone said . On a side note better use fseeko when you want to handle really large-files . Comment : fseek may allow seeking beyond the end of the file but there is nothing that states explicitly whether the file size is extended as a result . lseek http : pubs.opengroup.org onlinepubs 009695399 functions lseek.html explicitly states that seeking by itself will not extend the size of the file . In other words you d need some form of write operation to extend the size of the file when using lseek . However nothing forbids or allows fseek to behave the same way . C11 draft N1570 states If a read or write error occurs the error indicator for the stream is set and fseek fails . .. . Answer : http : en.cppreference.com w c io fseek .. . .. . POSIX allows seeking beyond the existing end of file . If an output is performed after this seek any read from the gap will return zero bytes . Where supported by the filesystem this creates a sparse file https : en.wikipedia.org wiki Sparse file .", "Question : I am working with 4 files and want to inject a string at a specified offset to each one of them.I am using fseek but the data is being written to the end of files instead of intended offsets.Why and how can i fix it : Comment : Mode a stands for a ppend . .. . Answer : The a mode means that the data will be written to end-of-file . Try using r+ mode read + write instead .

I know that in fact the filesystem is running in kernel space but in this context I consider them as two separates entities . When Bob UID 1001 GID 1001 groups humans minor tries to read file.txt which is let s say rwx r-- --x with owner Alice and group owner minor -- which one of the kernel and the filesystem permits access Does the filesystem have a function taking as parameters the entire list of Bob s groups Bob s UID and other stuff sent by the kernel which would allow the filesystem to determine whether Bob can or cannot read the targeted file Furthermore if this is the way it works -- how does the kernel know the data the filesystem needs for extended special attributes In the case of synology extended attributes ext4 btrfs for example . Many thanks for any help resources to read . .. . Answer : Good day to you In my opinion -- when the Kernel receives a request from a User for example to open a file it then analyses the User s access rights . If they are correct -- the Kernel manages the hardware to provide the User with the requested data . In a context of a computer system consisting of a Kernel and a File-System also including hardware to input to store and to output the data the File-System itself has no possibility of making decisions like the Kernel do it is just an informational structure written in a manner defined by the rules of operating it to which the Kernel must have an access in order to interact correctly these rules may be stored in the Kernel . So the Kernel makes decisions on providing access and if it is to fulfil the request the Kernel operates the data . And the File-System is a set of both stored data on some hardware and a software part as the instructions to the Kernel : how to manipulate the hardware s physical layer and maybe how to decide on access-providing on a logical layer but the decisive role again is up to the Kernel which must accord to all the provided rules . This variant is just a variant and it may vary in various operating-system realizations . I don t know in which of them it is implemented whether this is OS Linux or OS Windows approach or maybe not . And for example if we describe a remote cloud-storage to which the User connects -- this storage something in it that acts as a described Kernel maybe its Kernel decides whether to grant the access or not and the local Kernel acts as a User to which the remote system is like a Kernel .

Is there a way to create just a permission by itself I see you can create rules for Resources such as only allowing a user to edit posts which they are assigned to . The documentation does not appear to have much information on this . Any help would be greatly appreciated . Searched the internet but not finding much for this package . .. . Answer : I haven t used Authority although I am looking at it for a project . Based on my reading of the docs here s the way it works : .. . .. . The config file is there to specify configuration for the package . The roles permissions can be stored in the database although they don t have to be . The configuration file is there to tell the package how to work . So for example the config file allows you to set up aliases for one or more permissions - if you use aliases this needs to be done up front so that the package works the way you expect it to . As another example the rules more later can and should be set up in the config . Consider the following config from the Authority docs : .. . .. . What is this doing Let s go through it step-by-step : .. . .. . First this is specifying something that s supposed to happen when the application is initialized . Presumably there are other events that could occur but I m unsure why you d want to change the rules after the app is initialized . When the app is initialized the closure is called . The closure does this : .. . .. . 1 . gets the current user - later rules depend on who is logged in .. . .. . 2 . set up a couple of aliases - cuz we re lazy and don t want to specify rules for create read etc . one-by-one . We can just use manage instead . 3 . next it checks the current user . If they re an admin they get manage permissions for all resources . If your access-control info is stored in the database you could load it here and use that data to set up your rules . Now later on in the execution of your app you need to check and see if the user can for example create a user record . Do this in your controller : .. . .. . This checks the rules you set up in your config and determines if the user is allowed to do this . If they re not then in my example throw an exception . You probably want to handle it more gracefully . Authority gives you the flexibility to define your permissions much more precisely . For example .. . .. . This rule includes a check that allows a user to manage their own user record but nobody else s . To do this you need to adjust the example above . In this case the Authority instance gets passed into the closure as self then the current user ID is retrieved and checked against the user being edited user . If the user is trying to edit someone other than themselves the check fails . That s a very basic overview - hope it helps . Comment : Thanks for the detailed explanation . Definitely helps . In my application there will be a lot of rules and it just felt odd to place them in the config file .

Answer : I cannot actually provide a full answer and I can t add anything substantial to your own ideas except perhaps this : .. . .. . I suspect that a general approach to checking effective access rights does not exist simply because access rights depend heavily on the underlying file system s . For example checking access rights works quite differently on file systems that use the standard Unix rwx flags e.g . Linux ext2 ext3 than with file systems that support ACLs such as XFS http : oss.sgi.com projects xfs or NTFS . There might be several specific command-line tools that do what you want to do for specific file system types . Analogy : tools such as fsck mkfs may exist per file system type . Especially with UNIX-like operating systems where all kinds of file systems can be mounted in one big directory structure assuming only one specific permissions mechanism might lead to problems . If you build your own solution for this problem think about this fact first then decide exactly which access right mechanism s you want to support . I m not sure but I could imagine that Unix the POSIX specification prescribes the rwx access rights flags as a minimum that every Unix should support .", "Question : From my research I have found that the Authority package https : github.com machuga authority-l4 is best for implementing a role permissions based user auth system while maintaining flexibility .

Users are authenticated against AD and can successfully login to this server via SSH . Each user HOME has 700 permissions to disallow users to change and read other users files . Directory home public html is owned by Apache www-data : www-data and has permission 775 so each user members of group www-data can create his own subdirectory in home public html under his her username and create symbolic link-to it in his her HOME . Here is an example for a sample user with username jdoe43 : .. . .. . home Domain jdoe43 is a HOME directory it has permission 700 .. . home public html jdoe43 is a public html directory of user jdoe43 which is symbolically linked to home Domain jdoe43 public html .. . .. .

All that I tried with different set of permissions ended up either with Apache not to have access to users public html or with users to have at least read access to other users HOME or public html . I found several posts proposing to use selinux and configure file system to deny access to other users directories by means of permissions like I did with HOME by setting it to 700 and at the same time to grant Apache process by means of selinux to access home public html along with all its sub-directories . I also found some resources stating that selinux in recent versions of Ubuntu was replaced in favor of apparmor so as I have limited experience in this technology I decided to postpone any movements towards its implementation . Any suggestions recommendations are highly appreciated . Thank you . Comment : Ubuntu or serverexchange is the best place for this question . .. . Answer : There might be a selinux boolean that let you do such thing relatively painlessly . The ubuntu wiki sends you to the debian SELinux page which confirms that they use the same refpolicies as other distributions of course . I just checked the policy for apache and the boolean is there . If you already have a selinux-enabled ubuntu you can easily check whether the boolean is enabled with .. . .. . and check if the boolean true or false it defaults to false . As shown here http : www.if-not-true-then-false.com 2010 enable-apache-userdir-with-selinux-on-fedora-centos-red-hat-rhel after enabling UserDir you need to enable the boolean .. . .. . And relabel the directories for each user .. . .. . Note that unix permissions on the public html directory are still 755 or whatever you need for your user groups setup . If you wish to go the SELinux way that is what you need to do I don t know much about AppArmor and other alternatives but as you say the Ubuntu wiki is not very clear about selinux support .

Go to the Settings app navigate to the app s settings and toggle the camera permission .. . 4 . Double click home and go back to the app . After a few seconds it will refresh bringing you back to the first screen .. . .. . Note : I m using an iPhone 6 running iOS 8.4 .. . .. . I ve noticed this behavior on all apps that have the camera permission . My question is : Is there some way to prevent the app from refreshing restarting on resume after changing the camera permission It doesn t seem to happen when you toggle location services for example and from a usability perspective this is horrible . User scenario : If a user navigates deep into your app then needs to change the camera permission because say they accidentally clicked no last time they will be forced to navigate back to that screen when they return . This is especially harmful for an app trying to sell you something or sign you up for a new account . They might try to introduce a new feature where you can use the camera to take a profile-picture or scan your credit-card .

That link is in my question : It doesn t answer the question . .. . Answer : Well.. . In a Hybrid app one of the benefits of Worklight was that we own the native and web portion . You could create a Cordova plug-in based on the tutorials if you wanted but with SendActionToNative - because we own both sides - helped here by bridging the two ends negating the need for a Cordova plug-in . This feature is a Cordova plug-in in itself internally . In a pure Cordova apps we don t own both ends . Only the web end.. . The MFP SDK is now a Cordova plug-in . Anyway yes you could enter the platform folder where the native-code is and use those APIs and it should work but in a Cordova world that does not make much sense - you re not supposed to touch any native code.. . you re supposed to use Cordova plug-ins in order to interactive with the native later.. .", "Question : I m getting this error when I try to run on android .. . .. . mobilefirst-cli verb cli process.argv Applications IBM MobileFirst-CLI IBMnode bin node Applications IBM MobileFirst-CLI mobilefirst-cli bin mobilefirst-cli.js cordova run -d mobilefirst-cli verb cli opts debug : true argv : remain : cordova run cooked : cordova run --debug original : cordova run -d mobilefirst-cli verb cli mobilefirst@7.1.0.00.20151130-1653 mobilefirst-cli verb cli node@v0.10.36 mobilefirst-cli sill mfp cordova cmds running cordova command : run with args : -d What platforms do you want to run on android Searching for list of Devices.. .

Answer : It is not possible to upgrade the Cordova version provided by MobileFirst in the MobileFirst CLI . However the supplied Cordova version can be patched by IBM with any fixes that may be required this is done on a per-case basis for example in order to fix vulnerabilities . I can suggest you to upgrade to the latest available CLI from IBM Fix Central you can check for the version you are currently using by running the command mfp -v . Perhaps this issue is fixed there . If not then I suggest to open a PMR support ticket in order for the development team to investigate and possibly provide an iFix a build with a fix for the problem ." ] }

Comment : What s the name of your Windows user Does it have any special-characters in it It seems like your user name is substituted with @ @ @ for some reason . .. . Answer : I have Cygwin installed on Windows XP with GPS from GNAT GPL 2012 . If I have HOME set to C : cygwin users USERNAME and start GPS for the first time GPS says that it created the configuration directory C : cygwin users simon .gps . If I don t set HOME GPS creates the configuration directory C : Documents and Settings Simon which appears to be HOMEPATH . Note that GPS isn t aware of Cygwin it s a Windows application and uses your Windows environment-variables . I wonder whether you have HOME or perhaps HOMEPATH set to a nonexistent directory GPS doesn t seem to be able to create intermediate directories .", "Question : I m using GNAT Programming Studio to update some ada files . I have a style check which for these old files produces literally thousands of warnings . Helpfully GPS has a little auto fix wrench icon in the locations view that s great but I don t want to go through and click the wrench ten thousand times . Is there a way to have it correct these errors automatically without me having to click each wrench They are all right so I want to be changed automatically . I saw some documentation saying you could do it : http : www.adacore.com wp-content files auto update gps-docs Code-Fixing.html .. . .. . But I don t get the auto fix option when I right-click . Maybe you need the pro version I ve tried everything I can think of . This would save hours of work so it s really appreciated if someone could help on this . Thanks .. . Answer : This isn t an answer just an observation : - .. . .. . According to an AdaCore Developer Center posting http : www.adacore.com 2009 02 24 NF-44-F327-008-gps An auto fix is now offered for messages like suggested replacement automatically applying the replacement suggested by the compiler . That notice was posted 24 Feb 2009 . If you re not using GNAT Pro I m assuming you re using GNAT GPL 2009 which was released at the end of May 2009 . Now there s two months between those dates but generally AdaCore seems to and understandably upgrades their Pro version before migrating the upgrades into their GPL version . So that s my guess as to why you re not seeing that option in GPS . So...you can move to GNAT Pro wait for GNAT GPL 2010 I ve not heard anything about that yet but I d like to think it ll be out in a couple months wait for someone else here who has an actual answer via scripting or something or have one of your interns or minions do the clicking--unless you are a minion in which case you re SOL . Comment : Thanks for the reply yeah looks like I ll have to wait for the next free version or shell out for the pro version .", "Question : I ve started using GPS for coding Ada at work - does anyone have any tips for getting the best out of the IDE or any plugins I should be aware of For example is there a way to enable on the fly syntax type checking - of the sorts you get in eclipse visual-studio where errors are underlined as you go Also what are people s general opinions on GNAT Workbench compared to GPS thanks .. . .. . Matt .. . Answer : The GPS does not have a from of background syntax checking and that is by design . The idea behind GPS is that it is the compiler who decides what code is correct and what code is not correct . It means that if you want to know if your code is correct or not you have to compile it . On a Windows computer the short cut key for that is SHIFT+F4 and will only compile the specification or body file you are currently editing . Pressing F4 will compile your whole project . You will save time by using SHIFT+F4 . Another interesting feature is that the GPS uses cross-reference XREF information when navigation through the code . For example let s say you would like to find all the places in your code where a specific subprogram is called . In GPS GNAT PRO right-click on the subprogram you are interested in a press Find references . In the GPS GNAT Libre version you don t have a menu when right clicking in your code . In this case go to the Navigate menu and click on Find references there . If the GPS does not find any references and you know that the subprogram is used in the application it means that the XREF information needs to be updated . You may compile the whole application by F4 since the XREF information will be generated along with the binary that is produced . If you go to Edit and click on Key shortcuts you can set up a short cut key to generate the XREF information only . You may also find several interesting features there that you can set up a short cut key for . The cross-reference information XREF is also used for refactoring GNAT PRO specific functionality . It often works well for changing variable and subprogram names . Just make sure the cross-reference information is up to-date Code snippets in GPS are also useful . You use them by writing a keyword followed by CTRL+O not zero O as in Orwell . To see the code-snippets you can choose between go to Edit and click on Aliases . You can also create your own Aliases and code-snippets to become a more productive Ada Software Engineer . Good luck", "Question : null .. .

Sounds like some confusion between source and project files then . Comment : @trashgod : Thanks for the reply but then why not using GSP .. . Answer : On the command-line gnatmake will happily compile a file which contains Ada code but has the extension .gpr . GPS knows better than that and insists on treating myfirstprogram.gpr as a GNAT Project file which of course it isn t . You ll find life with GNAT much easier if you stick with its file naming-conventions : .ads for a spec .adb for a body and the file name needs to be the unit name in lower case . In your case the file should have been called hello.adb . The simplest approach to creating a GNAT project file in GPS is to go to the Project menu and select New . The only places where you must enter data are on the Naming the project page you might choose firstproject and the Main files page where you d click on the blue + to add hello.adb you can Forward through the others . After adding the main file you can click Apply to install the new project file now you can Build all and Run . You may find the GPS tutorial helpful Help menu GPS .. .

When I installed win32ada which I got from the Libre web site http : libre.adacore.com it said that it couldn t find a working Ada compiler and asked me to browse to one s location offering me C : GNATPRO . I changed this to C : GNAT 2012 and it was installed under there I see your equivalent would be C : GNAT - your compiler binaries are at C : GNAT bin mine are at C : GNAT 2012 bin including a win32ada.gpr in the place where GNAT expects to find it . There s no trace of a Bindings Win32Ada directory I wonder how yours got there", "Question : I am a huge fan of source code comments but the comments in the Ada standard-library are spartan at best . It is my understanding that the interface of the library is defined with the language definition but the implementation is left to the compiler manufacturer . I often wondered how they do it since the pure function names parameters and other definitions as I see them in the manual often don t explain what exactly the respective subprograms do and leave much to interpretation . I would expect some documentation along the line of the QT library . Why is it there no definition of the library with extensive comments for every function Comment : Almost all subprograms from Standard Library are very well documented together with exceptions and return values for example Ada.Strings.Fixed.Index returns 0 if Substring is not present in String . As such I don t see what is the problem . implementation defined subprograms have to be documented in user guide or reference in case of gnat they are documented gnat pro user guide or reference don t remember now which one Comment : Can you give an example of a language-defined subprogram where you ve found the RM s description to be inadequate I m asking because maybe the description really is there and you ve just had trouble finding it there are some places where the description s location isn t in the obvious place such as some I O operations . Comment : darkestkhan the GNAT library description in the FSF version of the GNAT RM https : gcc.gnu.org onlinedocs gnat rm The-GNAT-Library.html is very sparse the documentation is in the source files as Herr Doktor wants Comment : Just one example is the ADS file Ada.Containers.Doubly Linked Lists . there is no comment in there just the definitions for types subprograms etc . Looks to me like the designers assume that everybody has the same understanding for every identifier there but what if not and people assume different behaviour . Compare it for instance with Ada.Containers.Hashed Maps which at least contains some comments that explains functionality . To me as a newcomer this leaves much to guesswork .. . Answer : For an example the ARM section A.18.5 http : www.ada-auth.org standards 12rm html RM-A-18-5.html for Ada.Containers.Hashed Maps says in paragraph 1 - which would normally be referred to as A.18.5 1 - .. . .. . The generic library package Containers.Hashed Maps has the following declaration : .. . .. . so I guess that implementors have read this as an instruction . In the case of Hashed Maps you ll see at A.18.5 46 http : www.ada-auth.org standards 12rm html RM-A-18-5.html p46 a link-to A.18.4 which describes the common semantics of Maps and Length for example is at 25 http : www.ada-auth.org standards 12rm html RM-A-18-4.html p25 . GPS GPL from AdaCore Help GNAT has links to a local copy of the ARM GPS GPL 2014 only goes up to ARM2005 I don t know what the Debian version does . This is how it is that s not to deny you have a point about how it might be better", "Question : I ve installed GPS GPS 6.1.1 20150118 hosted on i686-pc-mingw32 GNAT GPL 2015 20150428-49 . It successfully compiles Hello World but even release executable is huge since it includes statically compiled not-optimized runtime and what is more important as far as I understand ada runtime is licensed under GPL and can not be statically linked into closed-source executable . How can I configure GPS gcc to link runtime dynamically Comment : The problem with GNAT vs GPL is that when you build against a particular RTS your involvement with the RTS is a your code may require instantiations of RTS code which effectively sucks the RTS into your application and b the interface between GCC and the RTS may have changed which makes it hard to replace one RTS with another at runtime i.e . by swapping dynamic libraries . .. . Answer : I will let someone else answer the specific question which is IMO a good one . Also good are related questions of minimising the runtime size where the full featured runtime is not necessary as for Hello World . Comparing the executable size with the memory installed on your platform one might conclude this is a case of premature-optimization . But for bare-bones executables e.g . on embedded microcontrollers it is certainly worth asking . However there is another implicit question : .. . .. . How do I divorce my executable from a GPL-encumbered runtime and I will answer this . Historically the Gnat RTS was not always so encumbered . At one time it featured the Gnat Modified GPL GMGPL https : en.wikipedia.org wiki GNAT Modified General Public License in which the runtime files contained additional permission above the GPL rights allowing you to link those components of the RTS with an executable without burdening your executable with the GPL - effectively allowing you to release such an executable under a closed-source license . Provided none of its other components were pure GPL . The Gnat GPL compiler comes with a pure GPL runtime completely legally to distinguish it from commercial offerings from the same authors - who have the right to put food on their own table and their commercial products http : www.adacore.com gnatpro have an excellent reputation and first class support . However there is another fork of the older Gnat compiler offered by the FSF as part of mainstream GCC https : gcc.gnu.org which is kept up to-date with modern Ada developments including Ada-2012 . In some respects it is ahead of Gnat GPL - in the underlying gcc version for example while in some respects it is behind as newer Ada features take longer to make it into the FSF branch . But the point here is that it inherited the GMGPL license and then the very similar Runtime Exception in GPLv3 . http : www.gnu.org licenses gcc-exception-3.1.en.html The linked Rationale and FAQ should let you determine if this satisfies your needs . If so . you can compile gcc including Gnat from source to meet your needs . This is not a trivial project however So for most common platforms you can find pre-built binaries of the FSF Gnat compiler from the imaginatively named getadanow.com http : getadanow.com .. . .. . Disclaimer : I am only pointing out this option . As always with licensing issues don t take the word of random guy on the internet but study the actual licenses of the compiler and RTS you are using and take appropriate legal advice . Comment : Licensing questions are always a major source of frustration . Adacore FAQ page states that A license guaranteeing that executables generated with GNAT Pro can be distributed under customer-specific terms and conditions . and that no guaranties are provided for GNAT GPL . I tend to understand this as GNAT is suitable for building closed-source executables just like gcc in general but you are doing it on your own risk . Another problem is that as an individual I can not take their commercial offers anyway minimum pack is 5 yearly licenses for a company . Comment : You are correct my answer should have pointed out that Gnat Pro licensing is different in this respect providing the permission you need . I use the FSF compiler when I cannot GPL my software . Comment : GNAT GPL effectively requires that you distribute applications with the GPL i.e . with your source . FSF GCC which has the GCC Runtime Library Exception as Brian notes allows you to distribute your applications on whatever terms you choose .

Every time I chose Debug- Initialize- program name the gui of GPS switches to that of the debug GUI and then an error pops up with could not initialize the debugger . The two possible solutions I have found are that gdb.exe may be out of date and it suggests running it outside of GPS which it does run fine . The other possible solution is to make sure the -g tags are applied when building the project as those are necessary for gnatlink and gcc for debugging . It also states that the -g tag is applied to a new project by default unless you have specifically removed it . I doubt I have but I am not sure where I would check that to make sure it is still included . The other odd thing is that the tutorial that comes with GPS that runs through how to build and debug your code works perfectly fine when I initialize debugging on it .

If its calling Siebel service Please explain about the web service Comment : I ve never worked with the Siebel integration but what I can say is that your problem is in your data in the ATG instance .

Answer : The error that you are getting is not because your request is using the incorrect Content-Type but rather that the response you are getting back from the endpoint of your SOAP call is returning an HTML response most likely a 404 error response . You will need to confirm that the endpoint you are trying to connect to is actually valid using some tool like SOAPUI and passing the SoapEnvelope you generated in the debug statement to the endpoint and confirm the response . Comment : I somewhat agree with your assessment to me it looks like whatever SOAP client that atg.siebel.catalog.SiebelCatalogTools is using that it is not sending the correct Content-Type header . It is hard to diagnose without knowing more about how the SOAP client was generated .", "Question : Our e-commerce application built on ATG has provision whereby multiple users can update the same Order . Since the cache mode for Order is Simple - this has resulted in large number of ConcurrentUpdateException and InvalidVersionException . We were considering locked cache mode however are skeptical about using locked caching as the Orders are being updated very frequently and locking might result in deadlocks and have its own performance implications . Is there a way we can continue using simple cache mode and minimize the occurances of ConcurrentUpdateException and InvalidVersionException .. . Answer : My experience has been that you have to use locked caching with orders on any medium to high volume ATG websites. . Also remember that the end-user experience is bad when this happens as they either get an error message if the error-handling is good or they get something like an internal server error error . The reason I believe you need to use locked caching for order is : .. . .. . 1 . You can t guarantee that a user has not got multiple sessions open at the same time which are updating the shopping cart which is just an incomplete Order . I have also seen examples where customers share their logins with family members etc and then wonder why all these items keep magically appearing in their shopping cart . 2 . There are a number of processes which update the order including things like scenarios and customer service agents using the CSC module . 3 . You could have code which updates orders in a non-safe way . Some things which might help include : .. . .. . Always use the OrderManager to load update an order . Sounds obvious but I have seen a lot of updating orders via the repository . Make sure that any updates are inside a transaction block . Try to consolidate any background processes which might update orders to run on a small subset of your ATG instances this will help reduce concurrency .. . .. . The ATG help http : docs.oracle.com cd E35319 01 Platform.10-2 ATGRepositoryGuide html s1005lockedcaching01.html has this to say about it : .. . .. . A multi-server application might require locked caching where only one Oracle ATG Web Commerce instance at a time has write access to the cached data of a given item type . You can use locked caching to prevent multiple servers from trying to update the same item simultaneously for example Commerce order items which can be updated by customers on an external-facing server and by customer service agents on an internal-facing server . By restricting write access locked caching ensures a consistent view of cached data among all Oracle ATG Web Commerce instances . That said converting to locked caching will most certainly require performance-testing and tuning of the order repository caches . It can and does result in deadlocks seen that many times but if configured correctly the deadlocks are infrequent . Not sure what version of ATG you are using but for 10.2 there is a good explanation here http : docs.oracle.com cd E35319 01 Platform.10-2 ATGRepositoryGuide html s0709maintainingitemconcurrencywithth01.html of how you can get everything in sync .", "Question : I have installed Oracle ATG v11 with the commerce reference store when I startup the production server and go to the url domain crs storeus I see the blank white page and have the following error in the console : .. . .. .

Problem is this method is getting called only when we click on create button from General tab present in users section but not on click of same create button from other tabs like Commerce Orgs Roles User Segments and Advanced . Please suggest .. . Answer : It is not a good idea to override getPropertyValue of an item for this implementation . The right way to do this is to work with the formhandler that is responsible for saving the user . It is a bit tricky to find this formhandler .

Answer : I would suggest you investigate using locked caching with isolation-level of serializable for the order repository item and sub items . This would mean that that the thread trying to authorize payment would acquire a write lock preventing other updates to the order . From the ATG documentation : .. . .. . A multi-server application might require locked caching where only one Oracle ATG Web Commerce instance at a time has write access to the cached data of a given item type . You can use locked caching to prevent multiple servers from trying to update the same item simultaneously for example Commerce order items which can be updated by customers on an external-facing server and by customer service agents on an internal-facing server . By restricting write access locked caching ensures a consistent view of cached data among all Oracle ATG Web Commerce instances . Setting up locked caching : .. . .. . 1 .

At the begining I thought it was possible to get atg profile from spring controller by reading this document http : docs.oracle.com cd E23095 01 Platform.93 ATGProgGuide html s0212nucleusresolverutil01.html by defining like this . But I have looked another atg documentation http : docs.oracle.com cd E23095 01 Platform.93 ATGProgGuide html s0807customizingarequesthandlingpipel01.html and found out that session scoped neclues like atg userprofiling Profile is not available if it does not go through atg DAF pipelining . Note : When you add your own servlets to the servlet pipeline bear in mind that you cannot access the session object until the SessionServlet locates or creates it . So if you add a servlet to the pipeline that needs to access the session object make sure that your servlet appears in the pipeline after the SessionServlet . Thus I tried to set PageFilter for spring servlets like the following . However it failed . The reason is that spring Controller is not a Servlet so that it cannot be at the end of ATG daf pipelininng . If I use a simple HttpServlet or DynamoServlet I can access user-profile . However I really need to use Spring Framework because my company wants to use it . Another reason is we are at servlet2.3 and I really want to use Spring annotations . Questions are .. . .. . 1 . Is there a way to get atg session scoped necleus from Spring controller without going through DAF pipelining 2 . Like a JSP page is there a way to set a spring controller at the end of ATG daf pipelining Comment : Have you considered accessing or exposing the profile via the out of the box web-services I have seen many attempts to implement so called true MVC in ATG and all of them have resulted in a world of pain and made upgrades of ATG almost impossible . The DAF pipeline is fundamental to ATG so bypassing is risky e.g . it has XSS filtering etc etc . I would really recommend that you reconsider your strategy . .. . Answer : Here I post the solution that I have found .. . .. . 1 . Is there a way to get atg session scoped necleus from Spring controller without going through DAF pipelining NO . we need to go through ATG DAF pipelining to get session scoped nucleus . 2 . Like a JSP page is there a way to set a spring controller at the end of ATG daf pipelining YES we can let Spring DispatcherServlet at the end of ATG DAF pipeline instead of direct servlet mapping in addition to the existing PageFilter Mapping .

Answer : If your legacy iText code can produce a bold font then it seems likely that the TTF file does actually contain a bold variant even if Flying Saucer doesn t use it . You may be able to use the bold variant in Flying Saucer if you specify the exact name of the bold variant in your CSS stylesheet . For example : .. . .. . You should be able to find the exact name of the font by opening a PDF generated by the legacy code in Adobe Reader .

Comment : Thanks - I m discovering this as well have since found even more example flying-saucer code showing the browser component displaying the glyffs on screen but which still fail to render on PDF using iText . .. . Answer : To support the big character set you need to specify a font file that has all those characters in it . Once you ve picked a font file you ll need your application to point to that file . I ve found that just putting the font files in your font s directory doesn t work . Try embedding the font too eg .

I ve spent many hours going through flying saurcer code but only when i saw your snippet i realized that woring with itext directly would be much more easy . Thank you . .. . Answer : I m no expert but if your font doesn t have a bold variant then Flying Saucer may simply not make it bold . When you programmatically make the font bold you re using a font class that could be behind the scenes making the font bolder on its own using some kind of internal mechanism . A good example of this in the real world is Photoshop : if you have a font that doesn t have a bold variety you can t make it bold but Photoshop has a simulated bold option that will go in and thicken up the symbols without really using a true bold face . A good means of diagnosing this for sure would be to switch which font you re using in Flying Saucer but keep the same document . If the new font is also not bold then the problem is less topical . If it does become bold then it is because there is no bold version of your font . Hope this helps . Comment : flying-saucer uses itext to generate the pdf . i was assuming that flying-saucer would use the same mechanism ie font.setStyle to apply the bold transform . clearly i am wrong and i don t dispute your answer in fact i agree 100 however i am looking for a solution not an explanation . my next stop is going through the flying-saucer source code however i d pay 50 rep for someone else to do this thanks anyway .

I ve been using flyingsaucer to format PDF documents for some time and always had to use an older version of iText for compatibility reasons . Now that I m using docx4j I need to update iText to a more recent version or it won t work . FlyingSaucer xhtmlrenderer R8pre2 uses iText 2.0.8 .. . docx4j 2.8.0 uses iText 2.1.7 .. . .. . I can only use one iText library but whichever one I use I end up with compatibility issues for either flying-saucer or docx4j . At the moment the problem seems to come down to one particular method com.lowagie.text.pdf.BaseFont.getCharBBox which in one version takes a char parameter and in the other it takes an int parameter . I think I may have to download sources for either flyingsaucer or iText I think they re both open-source and fix this myself not something I ve done before but I think I could manage but I can imagine I m not the 1st person to run into this problem and perhaps there s another way around it or someone else has already forked one of the projects to resolve this sort of issue . .. . Answer : Disclosure : I work on the docx4j project .. . .. . docx4j 2.8.0 only uses iText because it is required by our fork of Flying Saucer https : github.com plutext flyingsaucer which does the XHTML import . In that fork I added docx related stuff and removed some stuff we didn t need . It s possible that in the future we ll offer this back to Flying Saucer - it s a matter of having the time . In the meantime I mention for completeness that you can have the real Flying Saucer and our fork on your class path at the same time since our fork is re-packaged . Back to your question FlyingSaucer proper now has the same 2.1.7 dependency https : github.com flyingsaucerproject flyingsaucer blob master flying-saucer-pdf pom.xml so if you are able to use the current sources that should address the issue you have raised .

Answer : That is the correct behavior of the default tomcat service provided with Cloudify 2.7 - after a restart the tomcat files are re-downloaded and deployed locally . If you want a different behavior you may want to tweak the tomcat recipe to save the tomcat files in a different location the default installation saves all files in a per instance work directory which will be replaced after a reboot . You can change the recipe to look for an existing installation and use it if it exists .

These are probably the files you will need to edit to achieve what you are looking for . Note how catalina base is set as a context property and that AntBuilder is used to download the tomcat installation and save it to a shared location . These are the files you will need to change .

Each time I do I get a whole bunch of strange POST requests to my server . Some examples : .. . .. . What s going on here Is someone trying to launch an attack my firing off a ton of requests to randomly-generated localtunnel URLs .. . Answer : There are only 6700 or so unique localtunnel URL s and people misconfigure their apps to continue to send requests even after they are done using the URL . This is fairly common when using Localtunnel . You should upgrade to localtunnel v2 which has much stronger uniqueness requirements and should eliminate the random traffic .", "Question : I am using Video Module in Drupal 7 and utilizing Zencoder as an option for encoding videos .

We tried to download the file at .. . .. . The folder videos original has given public access . Please let me know where I am doing mistake or what permission or steps to perform to get the encoded file back to website . .. . Answer : Zencoder needs to be able to access the file over the internet in order to be able to download it so localhost isn t going to work . You might be able to use localtunnel.com again but my guess is the download-speed is going to be painfully slow . Just to test you may want to try pushing your code to a development server online or set Drupal to upload your files to a service such as S3 for Zencoder to access .", "Question : I have a local Vagrant VM on which I develop apps . I m tired of using Vagrant Share to provide public urls because it keeps disconnecting so I installed localtunnel.me .. . .. .

This breaks many of my connections with other webhooks and API services because the headers don t match the URL . Any ideas on how to overcome this besides ngrok which seems to be more resource intensive to run . .. . Answer : It turns out that LocalTunnel works a little differently to Vagrant Share . In order to make this work : .. . .. . You need need to add myproject.localtunnel.me to the ServerAlias line in the site s conf file which I had .

We want to publish an app that contains several html5 based games that promote language development . Currently I m looking at the intel app framework and xdk to do this . We plan to start with a simple game building words for example then adding more games over time . My question is this html 5 has a cache mechanism using a manifest . If I limit the games to a single page can I store the games on a web server rather than forcing the user to download all of the content with the app at the time of install The objective here is to allow games to be added without forcing updates of the app . I anticipate several Mb of sound clips and images per game . Thanks in advance . .. . Answer : You can use HTML5 Application Caching in remote website and load it in the app using Cordova InAppBrowser http : docs.phonegap.com en 3.3.0 cordova inappbrowser inappbrowser.md.html InAppBrowser so that when you click on a game it opens a InAppBrowser and loads the game from webserver this game can have the manifest with application cache so that all content is downloaded on the device and launched . You can develop the main app using Intel AppFramework http : app-framework-software.intel.com and load the list of games via a REST API from web server clicking on game can open a InAppBrowser and load the Application Cached game webpage from web server . This can all be done in Intel XDK http : xdk.intel.com .. . .. . Details on Application Cache can be found here http : www.html5rocks.com en tutorials appcache beginner Comment : First thank you for your answer . When the user opens a game for the first time it will require a network connection correct Also after they load the game for the first time will the InAppBrower keep the content cached according to the html5 manifest caching feature indefinitely Comment : Yes I did some test it did work not sure about indefinitely you will have to try . Comment : if you don t mind just one more question.. . If I spawn the Cordova InAppBrowser can I still make use of the Intel AppFramework or another framework jquery maybe in the game That should work right as long as the game html refers to the framework on the web server .

If it is quite sizeable the benefit of MVC is that it keeps things organized .

Any help is welcome . Thanks .. . Answer : According to apple documentation : .. . .. . Configuring the Keyboard for Web Views .. . .. . Although the UIWebView class does not support the UITextInputTraits protocol directly you can configure some keyboard attributes for text input elements . For example you can include autocorrect and autocapitalize attributes in the definition of an input element to specify the keyboard s behaviors as shown in the following example . You can also control which type of keyboard is displayed when a user touches a text field in a web page . To display a telephone keypad an email keyboard or a URL keyboard use the tel email or url keywords for the type attribute on an input element respectively . To display a numeric keyboard set the value of the pattern attribute to 0-9 or d . .. . These keywords and the pattern attribute are part of HTML 5 and are available in iOS . The following list shows how to display each type of keyboard including the standard keyboard .

What I need is a lightweight solution with a decent UI JQM is perfect for what I need in that domain . trigger.io and AppFramework seem to be the 2 solutions which are available maybe I m missing some others . I d like to give AppFramework a go but I d like to have feedback from people who have made the change . Thank you . .. . Answer : Intro .. . .. . A larger version of this answer can also be found HERE http : www.gajotres.net switching-from-a-jquery-mobile-to-appframework . jQuery Mobile http : jquerymobile.com was never intended to be used only as an HTML5 CSS3 hybrid-mobile-app framework . On a similar track like its older brother jQuery http : jquery.com and jQuery UI http : jqueryui.com it was intended to be used as a robust responsive solution in the ever growing mobile web application market . What it took from its older brother was an all around browser support . Run it on every possible major platform and it should work just the same . That same broad browser support also brought another problem and that is platform optimization . Because jQM can t favor specific platforms also means it is not optimized to use most in any of it . Let us also talk about Phonegap http : phonegap.com a bit . While great app packaging system it becomes a hell hole when used with a larger jQuery Mobile http : jquerymobile.com application . It s like two great parents made a deformed bastard child or to large pluses gave as an even bigger minus . Solutions .. . .. . Like always in human history another groups of developers came to fill this evident hole . And here came strike jqMobi http : www.jqmobi.com strike now AppFramework https : app-framework-software.intel.com jqTouch http : jqtjs.com Zepto http : zeptojs.com Sencha Touch http : www.sencha.com Trigger.io https : trigger.io and others . Good vs .. . .. . .. . Before going any further than jQuery Mobile one thing must be understood whatever you gain in speed and trust me you will get it you will lose in community support . While every earlier mentioned framework has a sizable developer community behind them all of them combined can t even come close to jQM . With this said let us delve into specifics . From my experience currently two best solutions as HTML5 CSS3 Android and iOS hybrid app frameworks are AppFramework and Sencha Touch . First let me say they are fast faster than jQuery Mobile will ever be if jQ developers stay on this course . UI support is similar if not even better in the case of Sencha Touch not to mention UI is more native looking that it is the case with jQuery Mobile . Listviews are faster scrolling is better transitions do not stutter . .. . bad .. . .. . Before someone asks why do people then choose to use jQuery Mobile instead The obvious reason would be community support and to some extent this is the truth . But there are some other pressing matters here . While jQMoby advertise it self as a truer jQuery alternative to jQuery Mobile it is a big lie . While still a great an excellent framework they are using this saying as a marketing trick . They have indeed cloned redone them a lot of jQuery features but this is only a partial job and veteran jQuery developers are going to find them self in a problem . They will not be able to make fully the most of their previous knowledge thus spending more time trying to find how to do something that was supposed to work than working on an app . On the other hand Sencha Touch doesn t suffer from this problem because it has a different almost alien syntax . Like with jqMoby you will need a lot of time to get into its syntax . But have no fear the result will be satisfactory in the end . One other thing unlike jQuery Mobile and Phonegap AppFramework and Sencha Touch has their native app packaging system . In my humble opinion this system is better than Phonegap because they are made to work with their js frameworks . Only thing Phonegap have over them is a HUGE plugin development community .

Conclusion .. . .. . AppFramework is probably the best choice for you . It has a similar design as jQuery Mobile so the syntax is not going to be a problem . Comment : Thank you very much for this answer . I had a look at your profile and I have seen that you ve given numerous pointers to enhance the use of JQM . I m going to try each point you raised for a last JQM attempt . Comment : I had tried sencha-touch on mac . First : installation sencha console make my folder dirty . Test speed on Android slow and buggy . For speed and small app i prefer use jQuery Mobile . Comment : Better late then never : Very good answer One more little tip though : If you go Appmobi on a large complicated project like I did definitely use the one with jQuery . It is only a fraction slower really not noticeable but you get all the jQuery functions . I still have pain in my ass for not using the jQuery one it wasn t there when I started . Comment : You mention if jQ developers stay on this course . By looking at jQM s roadmap isn t it true that the coming versions will be all about removing clutter and making things faster Comment : 1.4 already started with removing and it s a lot faster then 1.3 1.5 will go same way plus they will add some new stuff .", "Question : I have a mobile app developed using Intel s App Framework 2.0 App Framework MVC and Phonegap 3.2 .

I can not seem to get the sidemenu working . It is working fine on the demo you can download from the AppFramework website but no matter how well I am trying to mimic it - I can t get the sidemenu to work on my project . Everything is working fine until I add tags as that is how you make a sidemenu . When those tags are added the whole app will render blank white and an error pops up into console saying Uncaught TypeError : Cannot read property hideScrollbars of undefined . It has something to do with appframework.ui.js line 1100 that says this.scrollingDivs.menu scroller.hideScrollbars .. . .. . So it seems like this menu scroller is undefined for some reason . This is as much code as I can give you it is the index.html of my AppFramework Phonegap app : http : pastebin.com dXtTeiKx .. . .. .

I have tried the tags with AppFramework version 3.0 . I have also tried switching the JavaScript includes around a bit including appframework.ui before appframework and putting some includes to the bottom of the index.html but none if these have resolved the issue so far . I also tried removing all excess css and js includes but that did not work either .

If you are interested you can check my answer . : If you could be so kind and revert your downvote from my question so that people with the same problem can find this easier in the future - if you did downvote that is . .. . Answer : So I have successfully resolved the issue by myself . I don t know what kind of wizardry AppFramework does on the background but the issue that caused the nav not work for me was that I had a panel defined like so : .. . .. . The nav was correctly defined like so : .. . .. . The problem was with the panel like I said as you can see it has an id of menu - this is what broke the nav . Menu as an id for a panel is most likely a preserved word or something so it should not be used . I am suggesting that if you use AppFramework you should prefix everything especially panels with something like so : .. . .. . Here I prefixed the main panel with f prefix there is main as well but that s just extra so it tells about the panel more . So in short .. . .. . Prefix your panel ids and do not give any of them an id of main or menu . Use something like x main and x menu instead .", "Question : I found Intel s App-Framework to be light-weight and fast .

To achieve my goal I started a new project using AppDesigner and I followed the official Intel XDK video tutorials .

As said however the official video tutorials are outdated . So is there a more recent guide video tutorials are prefered but a book guide would be fine anyway that targets a more recent version of AppDesigner and covers almost every basic functionality Many thanks .. .

Comment : Let me know if you do not receive the invitation by Monday . Comment : I received the mail this morning . Thanks again", "Question : I have a mobile app developed using Intel s App Framework 2.0 App Framework MVC and Phonegap 3.2 . When I tap on a link MVC executes an action where I use the .ui.loadContent function to show the next panel but it doesn t seem to work properly on Android 2.3.7 because it only displays the mask that shows a Loading Content message but the panel is not displayed . What could be the cause of this behavior and how can I solve it in order to show another panel .. . Answer : I ve said this many times and many times it is the issue . jqmobi appframework is very specific to order . If something is not called in the right order css js functions it will budge on some platforms . Not a clue why specifically but it seems to be it every time . Try and reordering every script and function to match the example . More then once that worked for me .", "Question : I have an app and can t get the footer to go away . I can remove all the content from it but there is still space that isn t being used by the content . Also for some reason the side panel is leaving artifacts . Anybody ever have to deal with this .

What I couldn t find is how does it work . Does it bundle a JVM with the application for iOS and Win7 and uses Dalvik in Android Does it translates source code to native and do we have access to this source code Is there other magic considering they promise no compromise What limitations should I be aware while coding agnostic Java Preemptive strike : this is a question about Codename One not about which cross-platform should I choose or if I should go native or if I should go web . .. . Answer : Codename One https : www.codenameone.com uses a SaaS based approach so this might and probably will-change in the future to accommodate improved architectures . Notice that Codename One also provides an option to install its build servers in house https : www.codenameone.com corporate-server.html which means corporations that have policies forbidding such cloud architectures can install the cloud portion on premise . Currently on Android J2ME RIM the standard Java code is executed as is . Java 5 syntax is translated seamlessly to JDK 1.3 cldc subset on J2ME RIM to provide those language capabilities and API s across all devices . This is done using a server based bytecode processor based on retroweaver and a lot of custom code . Java 8 syntax is translated using retrolambda for all platforms when its used . This allows it to be compatible all the way down to RIM J2ME and also for newer non-Java 8 platforms such as Android . On iOS Codename One built open sourced ParparVM https : github.com codenameone CodenameOne tree master vm which is a very conservative VM . ParparVM https : github.com codenameone CodenameOne tree master vm features a concurrent non-blocking GC and it is written entirely in Java C . This effectively means that an xcode project is generated and compiled on the build servers so its effectively as-if you handcoded a native app and thus future proof for changes made by Apple . E.g . with recent 64bit and bitcode changes to iOS builds ParparVM needed no modifications to comply with those changes . In the past Codename One used XMLVM http : xmlvm.org to generate native-code in a very similar way but the XMLVM solution was too generic for the needs of Codename One . On Windows Phone a C translator is used currently it relies on XMLVM but it is not an ideal approach . Notice that the XMLVM backend that translates to C is very different from the one that was formerly used to translates to iOS . At this time Codename One is re-evaluating this backend and is considering a move either to ParparVM or to ikvm for this backend . JavaScript build targets which are available on the enterprise level use TeaVM http : teavm.org to do the translation statically . For desktop builds Codename One uses javafxpackager since both Macs and Windows machines are available in the cloud the platform specific nature of javafxpackager is not a problem . What makes Codename One stand out is the approach it takes to UI where it uses a lightweight architecture to allow the UI to work seamlessly across all platforms and be developed almost entirely in Java . It is augmented by the ability to embed heavyweight widgets into place among the lightweights . You can learn more about this in this blog post https : www.codenameone.com blog understanding-peer-native-components-why-codename-one-is-so-portable.html . A lightweight component is written entirely in Java this allows developers to preview the application accurately in the simulators GUI builder . Codename One achieves fast performance by drawing using the native gaming API s of most platforms e.g . OpenGL ES on iOS . The core technologies behind Codename One are all open-source including most of the stuff developed by Codename One itself e.g . ParparVM https : github.com codenameone CodenameOne tree master vm but also the full library platform ports designer tool http : github.com codenameone CodenameOne device skins https : github.com codenameone codenameone-skins etc .

FYI Shai Almog the author of this answer is the CEO of Codename One . Comment : Thanks for your attention Shai I think you should put it in your FAQ we know there s no real magic happening and like to know how the perceived magic works . I ll probably give it a try in evaluation phase Comment : There is no evaluation phase for Codename One our intention is to always have a reasonable free option for developers no strings attached . Since the product is open-source its important for us to carry some of that freedom into the SaaS services as well . Comment : Sorry I expressed myself wrong : P I m currently only searching for alternatives then we ll have an evaluation phase to see how the technologies meet our needs . Comment : Notice its highlighted in my bio and pretty much everywhere so its not as-if I tried to hide . I think it doesn t warrant being part of the answer since the answer should be judged by the facts rather than the bias of the author so I m moving that to the bottom but keeping the bold . I think the article is pretty objective . Comment : They are very disingenuous on their web page codenameone.com compare.html https : www.codenameone.com compare.html criticising Xamarin on most of the devices in the field it would require a 3rd party VM to be installed . which is technically true - Android IS most of the devices .

By the way is that true that there is a restriction to use java 1.5 in CodenameOne I couldn t find where to say to compile with java-7 . Kind regards .. . Answer : EDIT : This reply is somewhat out of date . Codename One https : www.codenameone.com supports a subset of Java 8 https : www.codenameone.com blog java-8-support.html now although string.split is still a problematic API call . Codename One supports a subset of Java 5 you shouldn t try and change that since the server translation code relies on bytecode behaviors of the target Java 5 and only supports a very specific subset of the API . The reasoning is simple since Codename One has multiple VM implementations iOS Dalvik ART XMLVM ParparVM https : github.com codenameone CodenameOne tree master vm blackberry etc . its really hard to test new stuff e.g . newer bytecodes and its really hard to add new API s in a way that will be totally cross-platform . You can use StringUtils.split to implement this functionality as well as StringTokenizer . Limiting the API s also allows us to keep the executable efficient and small relatively . Compared to a more full featured VM we are at least 5 times smaller in production . This is a big deal for mobile apps.. . .. . .. . We are working on consolidating the various VM s on the server-side which will allow us to add core VM API s more easily in the future as well as features like Java 8 support . You can learn more in this answer : How does Codename One work http : stackoverflow.com questions 10639766 how-codename-one-works Comment : For the most of the world who s used to working with Java 7 most likely this is quite a downer . When do you expect support for more recent versions of Java will be available Comment : Java 7 isn t much of an improvement we might support Java 8 lambdas in the future but don t have a concrete schedule . If you are referring to the full API I doubt that will ever happen.. . The full API is just too big and since we need to package the whole thing you will quickly hit the 100mb hard limit for OTA downloads in itunes . Comment : Updated the answer with newer details as Java 8 is supported now . Comment : The javadocs for the ShareButton class uses a try-with-resources . I couldn t get it to build because it told me that it s not supported in -source 1.5 . I tried setting the codename1.languageLevel property to 7 but that didn t work . Is there a way to use this Or is the ShareButton sample code simply incorrect Comment : We switched to Java 8 support a while back and since 3.3 have set it to the default . See the edit to this question .", "Question : I have to evaluate Codename One but I couldn t find infos about how the deployment works under the hood and what the end result actually is . Do they cross-compile my Java code to real native-code similar to RoboVM do they use a JVM similar to Gluon or do they have their own JVMs Comment : Codename One translates all the code to native-code or the native VM resulting in performance that matches or exceeds the performance of native-code . https : www.codenameone.com compare.html unfold the Fast option .. . Answer : You can see my answer here http : stackoverflow.com questions 10639766 how-codename-one-works 10646336 10646336 for additional details but the gist of it is that we are somewhat different than RoboVM . We translate the bytecode to C and compile it to native using xcode . Hence you get a fully native app and can even get the source code http : www.codenameone.com how-do-i---use-the-include-sources-feature-to-debug-the-native-code-on-iosandroid-etc and compile it yourself . Since native C Objective-C code is an officially supported path to iOS used by many apps games this is guaranteed to work always . RoboVM is a LLVM frontend for Java . This is rather ambitious and something that Apple just doesn t officially support . It created quite a few challenging situations for them in the past e.g . this post https : groups.google.com d msg robovm OnE3moz3d-8 nba0ury5CwAJ from a RoboVM employee explaining how hard it was for them to migrate to iOS 9.. . The same was true for the recent 64 bit transition etc . For us the migration to iOS 9 and to 64 bit was relatively painless our code base is also smaller since we limit the JDK usage to a set of supported classes for portability . Notice that our full VM is open-source under the vm tree here https : github.com codenameone CodenameOne . We initially used XMLVM and when RoboVM launched we thought about switching to them but decided writing our own VM would reduce risk . The VM portion is a very small piece of our solution e.g . we can translate your app to anything including a JavaScript app thanks to TeaVM http : teavm.org which supports threads on JavaScript . Unlike RoboVM Codename One is a true Write Once Run Anywhere solution .", "Question : I m prospecting alternatives to develop for multiple mobile platforms and have found Codename One http : www.codenameone.com that uses Java as lingua franca instead of HTML CSS JS or scripting languages . What I couldn t find is how does it work . Does it bundle a JVM with the application for iOS and Win7 and uses Dalvik in Android Does it translates source code to native and do we have access to this source code Is there other magic considering they promise no compromise What limitations should I be aware while coding agnostic Java Preemptive strike : this is a question about Codename One not about which cross-platform should I choose or if I should go native or if I should go web . .. . Answer : Codename one took very balanced approach to portability . I would like to add a pragmatic comment . From the user-interface side CN1 does paint all its UI on platform-provided canvas . It tries to mimic platform native look-and-feel if you choose it but has as much success as Swing had with its native platform look-and-feel because native platform constantly changes and native l f always lacks behind and in most cases feels not quite right . But if you choose platform-independent look-and-feel which is the sort of the trend today you are not restricted by Codenameone s default component set set in any way : it s just like Swing with its cross-platform look-and-feel Metal etc . . Which is good . From the language side : on iOS it is java compiled to C which is then tied to hand-written Objective-C and it does not bundle VM only portability layer . Most important here is the fact that java is compiled to C and not Objective-C which make it faster then idiomatic Objective-C code because it does virtual or more often direct method invocations instead of slow Objective C message dispatch . Which is good . It also may seem little faster on Android because while using Dalvik Art it does not use Android native UI which is bulky compared to CN1 s . This can make dynamic UI creation faster in runtime which is good . One of the strongest points of CN1 approach is its emulator implemented over desktop JavaFX canvas which you use to develop software . Emulator makes use of same UI code and portability APIs as on mobile platforms and lets you use IDE of choice for debugging . It restarts quickly and edit-compile-run cycle is very sustainable compared to android . Which is good . Second very strong point main one is open nature of their UI library all native-code and bytecode-to-C translator . If you spend some effort you can avoid building Android iOS ports on their farms and untie yourself from their particular revision of product but not from quite a few value-added services they offer which are not open-source . Depending on your situation this may or may not be quite good for you Weak point of Codenameone is its less-then-ideal maturity which means you can easily shoot yourself in the foot using basic UI components if you use them the way they were not indended to be used . Also it means that its java portability layer is not big enough and has holes in it to cover everyone s need and you may have to use native in some places and port other pure java libraries too . Also current state of graphics performance is sub-optimal if you get bunch of text on screen you ll easily miss 16msec fluid animation repaint time limit this can be worked around by double-buffering but it also has its limits . Luckily there is still room for optimization in implementation on both main platforms hopefully they will improve it . Overall Codenameone has good niche as a cross-platform framework for several classes of applications you may find a value in their services too .", "Question : I am trying to display a rounded image that I get straight from the Internet . I used the code below to create a round mask get the image from the Internet then tried to either set the mask on the image or the label itself . None of these approaches worked . If I remove the mask the image is displayed fine . If I keep the code to set the mask then all I see is an empty white circle . I have the idea that if I apply the mask on the image itself then it may not take effect because the image was not downloaded at the time the mask was applied . But I don t seem to understand why calling setMask on the label is also not working . .. . Answer : The Cloudinary API returns a URLImage which doesn t work well with the Label.setMask method because technically a URLImage is an animated image it is a placeholder image until it finishes loading and then animates to become the target image . I have just released a new version https : github.com shannah cloudinary-codenameone releases tag 1.1 of the cloudinary cn1lib which gives you a couple of options for working around this . I have added two new image methods . One that takes an ImageAdapter parameter that you can use to apply the mask to the image itself before setting it as the icon for the label . Then you wouldn t use Label.setMask at all . See javadocs for this method here http : shannah.github.io cloudinary-codenameone javadoc com cloudinary Url.html image-com.codename1.ui.EncodedImage-java.lang.String-com.codename1.ui.URLImage.ImageAdapter- .. . .. . The other method uses the new Async image loading APIs underneath to load the image asynchronously . The image you receive in the callback is a real image so you can use it with a mask normally . See javadocs for this method here http : shannah.github.io cloudinary-codenameone javadoc com cloudinary Url.html image-java.lang.String-com.codename1.util.SuccessCallback- .. . .. . We are looking at adding a soft warning to the Label.setMask and setIcon methods if you try to add an animated image and mask it so that it is more clear . Comment : That makes sense . I was under the impression that it may have been an image download issue . I will implement your suggestion . I think it is the right way to go forward .

I have already implemented this object as just an array byte of size 21 and an int that gives the index of the next not-yet-populated element and had great success using it . This seems like a simple implementation but doesn t java have build-in type for this kind of thing already I imagine the need for such a thing is extremely prevelant . I tried using a ArrayList Byte but it is super slow and my runtime scales exponentially with iterations . Am I suffering from boxing unboxing performance losses Which built-in type should I use as my resizable list of primatives Comment : what about LinkedList Byte it is the best option for first four clauses Comment : @AndrewTobilko : If ArrayList Byte is super slow in their use-case I can t see LinkedList Byte being much if any better . Comment : What s your motivation for making a change If you have something that works well for your scenario and you already know that ArrayList Byte doesn t suit.. . Comment : ArrayList amortized cost of appending at the end is more than outeweighed by its O 1 indexed access compared to LinkedList s O n Comment : I haven t tried but eclipse collections http : www.eclipse.org collections has some native collections . I am surprised by the lack of a list for native elements . I also wrote my own version of an ArrayList using int s called an IntList due to performance issues . Sometimes the boxing unboxing can have serious performance issues . .. . Answer : Standard Java does not offer collections for any of the primitive-types . But the compiler does a lot of auto-boxing for you and there are nice helper methods so going forward from byte to List Byte is probably not much work coding wise . But it seems you hit the the big problem with such code : it comes with performance cost . But this can t be assessed by talking about it on such a generic level . Long story short : if your environment allows you to turn to one of the recommend 3rd party libraries .. . just try them . If not you have to understand where your CPU cycles are coming from : .. . .. . a by profiling .. . .. . or .. . .. . b by extensive review if you have some sharp-eyed coworkers around - show them your code and then you try to figure where un boxing takes place and how to avoid it .. . .. .

Answer : Wouldn t List ArrayList String 2dlist new ArrayList ArrayList String be a better more efficient implementation Comment : If you re going with declaring List on the outside seems like you d want it on the inside as well as List List String .", "Question : The documentation says : .. . .. . Resizable-array implementation of the Deque interface . Array deques have no capacity restrictions they grow as necessary to support usage .. . .. . However I still want to understand what exactly the structure of ArrayDeque is how the resizing works . Also it would be great if someone could provide a reliable source where I can find the answer . According to some of the Google results I found it is possibly implemented as a circular array . Is it true And what is the grow policy Is it similar to ArrayList If it is does ArrayDeque have a similar performance to ArrayList in the operations like adding or removing the element at the end Thank you . Comment : Read the source code Comment : @chrylis Yes I m doing it now . It seems to me that it is a circular array . And the size doubles when it is full which makes the grow policy very similar to ArrayList . I don t understand why many people say ArrayDeque is faster than ArrayList . Comment : Who says it s faster They re different kinds of data-structures not alternative implementations . Comment : For adding elements at the beginning ArrayDeque is going to be faster because if it doesn t need resizing it will just decrement the head counter possibly wrapping around . ArrayList will copy over all elements to n+1 . But fit adding at the end they should be pretty similar . .. . Answer : The grow policy of ArrayList and ArrayDeque is not documented and may vary between JDK implementations and even JDK versions . For example in Open JDK 6 http : grepcode.com file repository.grepcode.com java root jdk openjdk 6-b14 java util ArrayList.java ArrayList.ensureCapacity 28int 29 it was n 3 2+1 but in Open JDK 8 http : grepcode.com file repository.grepcode.com java root jdk openjdk 8u40-b25 java util ArrayList.java ArrayList.grow 28int 29 it s n 3 2 . Also in JDK 6 ArrayList with default constructor was initially created with 10 elements array while in JDK 8 it allocates an array only when at least one element is added . The ArrayDeque http : grepcode.com file repository.grepcode.com java root jdk openjdk 8u40-b25 java util ArrayDeque.java implementation changes less often than ArrayList . It always uses internally the power-of-two sized array starting with 16 by default and doubling it when necessary thus memory-footprint may be different for ArrayList and ArrayDeque for ArrayDeque you will have in average less reallocations but more wasted memory . Addition to the tail is roughly equally fast for both ArrayList and ArrayDeque unless reallocation is necessary . Reallocation events may occur at different points . For example by default first reallocation for ArrayList will occur when adding element 11 but for ArrayDeque it will occur on element 16 . The advantage of ArrayDeque is ability to add remove elements to the head as fast as to the tail . In contrast ArrayList will do it in O n time as it will have to move all the existing elements . Thus use ArrayDeque when you need to add remove both to head and tail . If you need to modify the tail only usually ArrayList is preferred .", "Question : I was wondering how to initialise an integer array such that it s size and values change through out the execution of my program any suggestions .. . Answer : I disagree with the previous answers suggesting ArrayList because ArrayList is not a Dynamic Array but a List backed by an array . The difference is that you cannot do the following : .. . .. . It will give you an IndexOutOfBoundsException because there is no element at this position yet even though the backing array would permit such an addition . So you need to use a custom extendable Array implementation like suggested by @randy-lance Comment : I believe you wanted to link it to codereply.com answer 6i5bur java-dynamic-arrays.html http : codereply.com answer 6i5bur java-dynamic-arrays.html", "Question : I try to add objects in a List String instance but it throw an UnsupportedOperationException . Anyone knows why My Java code : .. . .. . The error message : .. . Answer : Not every List http : download.oracle.com javase 6 docs api java util List.html implementation supports the add method . One common example is the List returned by Arrays.asList http : download.oracle.com javase 6 docs api java util Arrays.html asList 28T.. . 29 : it is documented not to support any structural modification i.e . removing or adding elements emphasis mine : .. . .. . Returns a fixed-size list backed by the specified array . Even if that s not the specific List you re trying to modify the answer still applies to other List implementations that are either immutable or only allow some selected changes .

I would like to convert this array into an object of the ArrayList class . .. . Answer : Comment : Yep . And in the most common case where you just want a list the new ArrayList call is unecessary as well . Comment : @Luron - just use List ClassName list Arrays.asList array Comment : @Calum and @Pool - as noted below in Alex Miller s answer using Arrays.asList array without passing it into a new ArrayList object will fix the size of the list . One of the more common reasons to use an ArrayList is to be able to dynamically change its size and your suggestion would prevent this . Comment : Arrays.asList is a horrible function and you should never just use its return-value as is . It breaks the List template so always use it in the form indicated here even if it does seem redundant . Good answer . Comment : @Adam Please study the javadoc for java.util.List . The contract for add allows them to throw an UnsupportedOperationException . docs.oracle.com javase 7 docs api java util http : docs.oracle.com javase 7 docs api java util List.html add 28E 29 Admittedly from an object-oriented perspective it is not very nice that many times you have to know the concrete implementation in order to use a collection - this was a pragmatic design choice in order to keep the framework simple .", "Question : I need to know if i store my data in an ArrayList and I need to get the value that I ve stored in it .. . .. .

Here is a more detailed article : .. . http : www.codeproject.com Articles 4894 Pointer-to-Pointer-and-Reference-to-Pointer", "Question : I was experimenting with C++ and found the below code as very strange . I know that the virtual method call crashes because it requires a vtable lookup and can only work with valid objects . I have the following questions .. . .. . 1 . How does the non virtual method say hi work on a NULL pointer 2 . Where does the object foo get allocated Any thoughts Comment : See this http : stackoverflow.com questions 2474018 when-does-invoking-a-member-function-on-a-null-instance-result-in-undefined-behav for what the language says about it . Both are undefined-behavior . .. . Answer : The object foo is a local variable with type Foo . That variable likely gets allocated on the stack for the main function just like any other local variable . But the value stored in foo is a null-pointer . It doesn t point anywhere . There is no instance of type Foo represented anywhere . To call a virtual function the caller needs to know which object the function is being called on . That s because the object itself is what tells which function should really be called . That s frequently implemented by giving the object a pointer to a vtable a list of function-pointers and the caller just knows it s supposed to call the first function on the list without knowing in advance where that pointer points . But to call a non-virtual function the caller doesn t need to know all that . The compiler knows exactly which function will get called so it can generate a CALL machine-code instruction to go directly to the desired function . It simply passes a pointer to the object the function was called on as a hidden parameter to the function . In other words the compiler translates your function-call into this : .. . .. . Now since the implementation of that function never makes reference to any members of the object pointed to by its this argument you effectively dodge the bullet of dereferencing a null-pointer because you never dereference one . Formally calling any function even a non-virtual one on a null-pointer is undefined-behavior . One of the allowed results of undefined-behavior is that your code appears to run exactly as you intended . You shouldn t rely on that although you will sometimes find libraries from your compiler vendor that do rely on that . But the compiler vendor has the advantage of being able to add further definition to what would otherwise be undefined-behavior . Don t do it yourself . Comment : Good answer . Thanks Comment : There also seems to be confusion as to the fact that the function code and the object data are two different things . Have a look at this stackoverflow.com questions 1966920 http : stackoverflow.com questions 1966920 more-info-on-memory-layout-of-an-executable-program-process . The object data is not available after the initialization in this case because of the null-pointer but the code has alsways been available in memory elsewhere . Comment : FYI this is derived from C++11 : 9.3.1 2 : If a non-static member function of a class X is called for an object that is not of type X or of a type derived from X the behavior is undefined . Clearly foo is not of type Foo as it doesn t exist . Comment : Actually in hindsight it s more directly derived from C++11 : 5.2.5 2 : The expression E1- E2 is converted to the equivalent form E1 .E2 and then the obvious UB of dereferencing E1 when it s not a valid pointer inc .

Comment : It does the hokey pokey and spins itself around Comment : @haylem : strictly interpreting the standard assigning zero doesn t actually require any paritcular state in the pointer except to make it be a null-pointer . a null-pointer should be convertable back to 0 but it could have any possible storage structure . On systems where it s not possible to make an address read from the 0 address be an error it could have some other value hypothetically 0x8c000000 which won t be in ram or rom .. . Answer : A pointer to 0 is called a null-pointer and is usually used to indicate that it is not pointing to anything . This can be checked for by the debugger runtime compiler whatever to be sure you don t have a pointer to invalid data . It s just an explicit recognition that the pointer isn t supposed to be pointing to anything just now .", "Question : I am writing a function to load text from shader code file .

Answer : I thought that passing a pointer only would suffice to change its content . Passing a pointer suffices to change the content of the pointee the thing pointed to . That s great and it has essentially the same effect as passing a reference . But you re not doing that . You want to change the pointer itself . Consider if you wanted to pass an object into a function such that the function altered the original object . Let s call the object s type T and let s pretend that it has a member function mutate that changes it somehow so that we don t have to give a real-world example of this as T changes : .. . .. .

The scenario that you re thinking of is passing some non-pointer object by pointer to mutate it : .. . .. .

Where is this stored in memory .. . Answer : Other answers have done a very good job explaining how a typical compiler implements this by passing it as an implicit first parameter to the function . I think it s also useful to see what the C++ ISO spec explicitly says about this . According to the C++03 ISO spec 9.3.2 1 : .. . .. . In the body of a nonstatic 9.3 member function the keyword this is a non-lvalue expression whose value is the address of the object for which the function is called . It s important to note that this is not a variable - it s an expression much in the same way that the expression 1 + 2 3 is an expression . The value of this expression is permitted to be stored pretty much anywhere . The compiler might put it on the stack and pass it as an implicit parameter to a function or it might put it in a register and it conceivably could put it in the heap or in the data segment . The C++ specification deliberately gives the implementation some flexibility here . I think that the language-lawyer answer is this is completely implementation-defined and moreover this is technically not a pointer but an expression that evaluates to a pointer .

There is no segmentation-fault when a memory location pointed by ptr is not allocated by other object program right How to explain that Comment : This is called undefined-behavior . Basically anything can happen - literally . I ve seen cases of it which caused values to be treated as both true and false at the same time . Comment : By the way the code you show doesn t sport a dangling-pointer - in the commons sense of the term . It is usually called uninitialized pointer . Dangling pointer is something which was valid sometime ago but not any more . Comment : In C++ there are few reasons to use a pointer at all . Comment : In C++ there are few reasons to use a raw pointer at all . Pointers to allocated memory should be wrapped in resource management classes and code outside of those classes should rarely need raw pointers to allocated memory . Pointers to non-heap memory are still sometimes useful and of course somebody needs to write the resource management classes . .. . Answer : Since ptr is never initialized it may point to anything - code data stack unmapped memory memory that is mapped but not in an in-use range . That is the address in the ptr member variable could contain random leftover data special values generated by the compiler or heap implementation or Reasoning about why you do or do not get a segmentation-fault in these circumstances is not particularly useful or meaningful in most cases . Just don t do that . It s undefined-behavior and can cause arbitrarily unpredictable things to happen . Comment : What s often overlooked : Undefined behavior doesn t just apply to the single statement that causes it but to the program as a whole . If you trigger UB you are left without a single guarantee . Comment : BTW understanding what actually happens in these circumstances can be useful when investigating crashes but the advice of don t do that still applies .

This isn t a call to A : : f . It is a call to B : : g . is transformed by the compiler to an ordinary function-call : .. . .. . Is the this-pointer a pc or B pc Neither . It is a B . Another question is how the compile knows where the member-functions are It doesn t . It knows their names . The linker assigns their addresses . Question 2 : .. . .. . 1 How does the compiler know the second function pointer should point to the class B s implementation of the g How the compiler figures it Because it is C s vtbl and C inherits from B and B has the nearest definition of g . 2 In the above example all members are int and we assume that the compiler assigns 4 bytes memory for the int . What if the member is char does the compiler still assigns 4 bytes memory for the char Or just one byte It depends on the alignment and packing rules of the processor the compiler compiler-options surrounding pragmas etc . 3 pc 1 pc 2 the this-pointer here is a pc why not B pc This supposition contradicts your other question http : stackoverflow.com q 30747633 207421 . It is B . Is there any rule for the passing this-pointer See above . Comment : thanks so much for your answer . I have another question : stackoverflow.com questions 30747633 http : stackoverflow.com questions 30747633 compilers-detail-of-this-pointer Can you please help me take a look at it Comment : For question 2 the function-pointers are pointed to appropriate functions at runtime or at the compile step", "Question : I am trying to explore this-pointer in c++ . I have created a pointer to class object and caling a function to delete the current object but the behavior is unexpected . Why output of the last print statement is x 0 y 6 . Comment : Behavior of deleting this is undefined . At least behavior accessing it afterwards is undefined . Comment : What behavior did you expect Comment : I understood that the behavior is undefined after deleting this-pointer . But why the value is set as x 0 and y 6 .. . Answer : Deleting this is legal which calls the destructor of class .. . .. . However if the object was not allocated using new it will be a Undefined Behavior .. . .. . But you have to be absolutely sure that this will be last member function invoked on this object and none of of your member function after the delete this line gets called through this object since this will become a dangling-pointer which should not be dereferenced . If you do these the behavior will be undefined so can see anything in your output . Comment : thank you so much for the explanation .", "Question : As mentioned in the title I would like to know about the type of this-pointer . I m working on a project and I observed that the type of this-pointer is ClassName const this on windows using VC++ 2008 . Well I would want to know what is the need requirement to make the this-pointer a constant pointer . Thanks . .. . Answer : The type of this-pointer is either ClassName or const ClassName depending on whether it is inspected inside a non-const or const method of the class ClassName . Pointer this is not an lvalue . The observation you mentioned above is misleading . Pointer this is not an lvalue which means that it cannot possibly have ClassName const type i.e . it cannot possible have a const to the right of the . Non-lvalues of pointer type cannot be const or non-const . There s simply no such concept in C++ language . What you observed must be an internal quirk of the specific compiler . Formally it is incorrect . Here are the relevant quotes from the language specification emphasis mine .. . .. . 9.3.2 The this-pointer .. . .. . In the body of a non-static 9.3 member function the keyword this is a prvalue expression whose value is the address of the object for which the function is called . The type of this in a member function of a class X is X . If the member function is declared const the type of this is const X if the member function is declared volatile the type of this is volatile X and if the member function is declared const volatile the type of this is const volatile X . Note : thus in a const member function the object for which the function is called is accessed through a const access path . end note Comment : Exactly what I was expecting . But I do not see that way . the behaviour I m observing is inside a non-const method of the so called ClassName class . Well I get to know the type using the VC++ intellisense which displays the type when you scroll over the variables . Could this be the possible reason why I m getting incorrect type information . Comment : @Purnima : The type information you see is probably restricted to error messages only and to Intellisense and stuff like that . I m sure the core language sees the correct type of this . I.e . if you inspect the type of this using typeid it will not have const to the right of the . Comment : @Andrey : Thank u for the prompt response . I indeed checked using typeid and got the correct type as expected . Comment : I couldn t agree more hmm if there is no C++0x standard . After that this may have a type of rvalue pointer if the object is a tmp obj like ClassName .call . Comment : @Purnima : No . That means that your C++ Primer 4th ed is incorrect . I don t know whether this is a deliberate error for simplification or genuine error in the book but saying that this is a const pointer is always incorrect . Again this is an rvalue of scalar type . Rvalues of scalar type cannot be const or non-const . The fourth edition was published in 2001 which means it is rather old . It probably makes sense to check the later editions . The error might be fixed there .", "Question : i have main class that i like to pass its pointer reference to on of the objects i creating but it gives me error : .. . .. . Error 1 error C2664 : GameController : : GameController GameLayer : cannot convert parameter 1 from GameLayer const to GameLayer .. . .. . what i have in the GameLayer the main object .. . .. . and in the GameController i have this constructor .. . .. . the resone is i need to be able to modify the data in GameLayer from GameController GUI stuff Comment : Why does it need to be a reference I m going to go ahead and bet that it probably doesn t . Comment : this is not a GameLayer . It s either a GameLayer or a const GameLayer depending on the constness of the currently running method . Comment : Also note that instead of a variable you re using the type name itself in the constructor . GameController GameLayer GameLayer shouldn t it be GameController GameLayer gameLayer Comment : Please avoid pointers : GameController GameLayer GameLayer and than m GameController GameController this - this does not address const correctness .. . Answer : First the type of this could be GameLayer const or const GameLayer const depending upon whether the member function is const or not . But it is a const pointer . Having said that a reference to a pointer type ref means indicates that you will be modifying the pointer the object which it is pointing to . Since this-pointer is a constant pointer you cannot assign that to a non-const pointer GameLayer p in the context of references . In case of references to pointer you cannot assign to a reference which will modify the value in this . You cannot assign it to a reference to a non-const pointer GameLayer p but you can assign a reference to a const pointer i.e . GameLayer const p . So changing the constructor to GameController GameLayer const gameLayer should work . But I don t see any use of it here currently . And if you re calling from a const member function then this has the type const const so you will have to change it to GameController const GameLayer const gameLayer . Comment : Since this-pointer is a constant pointer you cannot assign that to a non-const pointer GameLayer p -- Yes you can . Comment : Specifically : the set of all things that can be used to initialize GameLayer is identical to the set of all things that can be used to initialize GameLayer const . The const in that location only affects whether you can assign to p it doesn t affect what you can initialize it with . The difference between initializing GameLayer and initializing GameLayer const is as you say . Comment : @SteveJessop : Yes I agree . But isn t what is written above true Comment : @Uchia : No what you wrote is not all true . The part that is not true is Since this-pointer is a constant pointer you cannot assign that to a non-const pointer GameLayer p but you can assign it to a const pointer GameLayer const p .

Of course I did . Tell me if I was blind to the answer . Comment : I m pretty sure that this sort of information is deliberately not exposed in the library and thus inaccessible in a portable way . .. .

Example in the above article : .. . .. . In the article the author introduces that the memory layout of object d is like this : .. . .. . The question is about d- f2 . The call to d- f2 passes a B2 pointer as a this-pointer so we have to do something like : .. . .. . Why should we pass a B2 pointer as the this-pointer not the original D pointer We are actually calling D : : f2 . Based on my understanding we should pass a D pointer as this to D : : f2 function . update .. . .. . If passing a B2 pointer as this to D : : f2 What if we want to access the members of B1 class in D : : f2 I believe the B2 pointer this is shown like this : .. . .. . It already has a certain offset of the beginning address of this contiguous memory layout . For example we want to access b1 inside D : : f2 I guess in runtime it will do something like : this+4 this points to the same address as b2 which would points b2 in B .. . Answer : We cannot pass the D pointer to a virtual function overriding B2 : : f2 because all overrides of the same virtual function must accept identical memory layout . Since B2 : : f2 function expects B2 s memory layout of the object being passed to it as its this-pointer i.e . the overriding function D : : f2 must expect the same layout as well . Otherwise the functions would no longer be interchangeable . To see why interchangeability matters consider this scenario : .. . .. . B2 : : test needs to make a call of f2 in both scenarios . It has no additional information to tell it how this-pointer has to be adjusted when making these calls . That is why the compiler passes the fixed-up pointer so test s call of f2 would work both with D : : f2 and B2 : : f2 . Other implementations may very well pass this information however multiple-inheritance implementation discussed in the article does not do it . Comment : 1 what do you mean by interchangeable can you explain a little bit more detail 2 If passing a B2 pointer as this to D : : f2 what if we want to access the members of B1 class in D : : f2 For 2 please see the update of the question . Comment : Thanks so much Please verify me . B2 b2 b2.test it s a B2 pointer passed as this to B2 : : test definitely since b2 is a standlone object . For D d d.test the compiler passes the fixup pointer which actually points to the sub-object B2 of D as the this to test since the actually calling function is B2 : : test . If the this does not point to B2 inside D it would cause problems when accessing the members of B2 inside the function B2 : : test . This is why I think we should pass a fixup pointer as this . This example cannot explain the update . Thanks still Comment : For D d d.test I agree we do something like d.test B2 b2 means this points to sub-object B2 of D . However inside B2 : test b2- f2 should execute D : : f2 . Am I right Now the problem becomes what kind of this is passed to b2- f2 Comment : Also consider the common situation of void foo const B2 b2 b2.f2 . Calling foo with an object of type D needs to work but there s no possibility for foo to be able to pass a this-pointer of type D . So the compiler must compile D : : f2 assuming that the this-pointer hidden parameter is to a B2 type . However it can assume that the hidden pointer parameter is pointing to the B2 type that is embedded in a D type . So the function still has access to members of D but must adjust the passed in this-pointer appropriately and automatically . Comment : @FihopZz inside B2 : test b2- f2 should execute D : : f2 You are absolutely right That s precisely the reason why this-pointer passed to test must be that of B2 inside D because test has no way to adjust the pointer for the call of D : : f2 . Therefore it passes its own this regardless of how it was called and it works because both B2 : : f2 and D : : f2 expect an identical layout of what is passed through this-pointer .", "Question : What is this in the following QT function-call I know the background of this in C++ but what is this pointing to in this function-call Comment : Pointer to instance of the class where you call the connect .

Just plain this please . .. . Answer : For beginners this is often depicted as a constant pointer . However this is actually a prvalue pure rvalue of pointer type . You can t assign anything to prvalues of fundamental type which implies the const-ness of this . The exact type of this depends on the cv-qualification of the method . A rule of thumb is that the cv-qualification is simply prepended to the usual pointer type - i.e . if a method of Class is marked const then the type is const Class . if the compiler can compile it fine whether there is a const or not why does it matter If and only if the pointee type of this is const you can t modify the members of the class . The const -qualifier on methods allows you to distinguish between methods for const objects and methods for non- const ones which is often a necessity .", "Question : I m reading Bjarne s paper : Multiple Inheritance for C++ https : www.google.com url sa t rct j q esrc s source web cd 1 cad rja uact 8 ved 0CB4QFjAAahUKEwj30Mntr4TGAhVJbK0KHZVGAG8 url http 3A 2F 2Fwww.usenix.org 2Fpublications 2Fcompsystems 2F1989 2Ffall stroustrup.pdf ei Z8h3VbeBM8nYtQWVjYH4Bg usg AFQjCNHPqDyiu0Gc700VQ-3h 98GX0A Ig sig2 XB1KwzmY14xMvZig6Wrwjw bvm bv.95039771 d.b2w . In section 3 page 370 Bjarne said that The compiler turns a call of a member function into an ordinary function-call with an extra argument that extra argument is a pointer to the object for which the member function is called . I m confused by the extra this argument . Please see the following two examples : .. . .. . Example 1 : page 372 .. . .. . A class c object C looks like : .. . .. . C : .. . .. .

Why we cannot know the B object pointed to by pb is part of a C at the compile-time Based on my understanding B pb new C pb points to a created C object and C inherits from B so a B pointer pb points to part of C . 3 Assume that we do not know B pointer to by pb is part of a C at the compile-time .

Answer : According to the C++ Standard 9.3.2 The this-pointer .. . .. . 1 In the body of a non-static 9.3 member function the keyword this is a prvalue expression whose value is the address of the object for which the function is called . The type of this in a member function of a class X is X . If the member function is declared const the type of this is const X if the member function is declared volatile the type of this is volatile X and if the member function is declared const volatile the type of this is const volatile X .

As for you then you mix two types a constant pointer and a pointer that points to a constant data . For example this declaration .. . .. . does not declare a constant pointer .

As for this quote from your book .. . .. . after all the body of isbn doesn t change the object to which this points so our function would be more flexible if this were a pointer to const .. . .. . Then it means that it would be better to define the function with qualifier const . In this case it could be called for constant and non-constant objects . Otherwise it may be called only for-non constant objects because within the function the pointer type of this is not const ClassTYpe .

The application also uses a Third Party Control i.e . FPSpread7 for WinForms by ComponentOne Studio . Although the tools UISpy and Inspect.exe show the spread as part of the automation tree however the rows and the columns within the spread are not visible in these tools . I posted the query to the ComponentOne Studio team and they said that the UI automation provider is not implemented for their control and is in development pipeline . So is there any other way that I could automate this specific control Or is it possible to create a proxy provider for it or for any third party control for that matter using which I can automate the control Note : Link to the ComponentOne website : http : www.componentone.com Comment : In the general case you can t . For example suppose I write a super-secure control that displays protected information banking military etc . I don t want anyone to be able to automate anything form it . For specific cases it may be possible using various hacks and trics but if you see nothing in UISpy nor Inspects odds are it s probably not possible . Comment : So apart from UIAutomation Framework provided as part of .Net which is consumed by White Framework as well is there any other tool framework which I can look at that might help in such a scenario Comment : Or there is nothing that I can do except to wait for the development team of WinSpread to provide the required support for it . Comment : UI Automation is much lower than .NET it s provided by Windows itself . I don t think there s much to do at this stage if WinSpread doesn t provide anything . For example let s suppose what WinSpread does is only drawing unstructured bitmaps on the screen the only solution would be to write something that recognizes these bitmaps . This is the kind of limitation that one should take in account when choosing 3rd parties IMHO . Comment : Thanks for the information . i ll check if I can work something out with bitmaps . .. . Answer : Actually Spread is a very complex control and supporting UI automation in such complex controls requires a special custom property provider DLL .

Answer : ComboList in C1FlexGrid in a ComponentOne Studio for Winforms works analogous to ComboList in DatGridView of MS Controls . ComboList can be editable in C1FlexGrig in VB10 . In fact it is an important and widely used functionality of C1FlexGrid . .. . .. . The ComboList property of C1FlexGrid enables this functionality . It specifies the type of editor to be used when editing a cell . You may use a text box drop-down list drop-down combo or an edit button to pop-up custom editor forms . To use the ComboList property set the AllowEditing property to true and respond to the BeforeEdit event by setting the ComboList property to a string that describes the type of editing you want to use for that cell . The options are described below : .. . .. . To edit the cell using a regular text box set the ComboList property to an empty string . For example : .. . .. . flex.ComboList string.Empty .. . .. . To edit the cell using a drop-down list set the ComboList property to a string containing the available options separated by pipe characters . For example : .. . .. . flex.ComboList Item 1 Item 2 Item 3 .. . .. . To edit the cell using a drop-down combo set the ComboList property to a string containing the available options separated by pipe characters and starting with a pipe character . For example : .. . .. . flex.ComboList Item 1 Item 2 Item 3 .. . .. . To display an edit button set the ComboList property to a string containing an ellipsis .. . . Edit buttons look like regular push buttons aligned to the right of the cell with an ellipsis as a caption . When the user clicks on the edit button the grid fires the CellButtonClick event . In this case the user can t edit the cell contents directly . For example : .. . .. . flex.ComboList .. . .. . .. . To display an edit button next to an editable cell set the ComboList property to a string containing a pipe and an ellipsis .. . . In this case you get a regular edit button but the user can also edit the cell contents directly . For example : .. . .. . flex.ComboList .. . .. . .. . Example : .. . .. . The code below handles the BeforeEdit event and assigns a value to the ComboList property so that the grid displays buttons on every other row .", "Question : We are investigating alterntive control libraries for a new project we are working on .

I applied AutoSizeColumns like this : .. . .. . but this didn t help.. . Thanks Comment : changed this to be an answer .. . Answer : Using GridLength.Auto usually doesn t work for these column widths because of virtualization . FlexGrid has a couple methods to autosize the columns but the columns must be visible or they won t be calculated and will remain the static width . Here https : gist.github.com f5bdb54009b71466d271 is a very non-production-worthy example of how to do this . FWIW this is why I never liked ComponentOne controls -- it felt like they were stuck in WinForms mode . edit : Adding some code for CM-specific usages . As far as whether or not accessing the view from a viewmodel is compliant with MVVM theories -- technically it is not but sometimes you are forced to use controls that just cannot be automatically configured through XAML and you can t use the View s code-behind because of one reason or another . Comment : Thank you for your answer . But as I use Caliburn.Micro without code-behind is it possible to do it in xaml Comment : Although it deviates slightly from the loosely-coupled MVVM pattern you can still access your View from your ViewModel . CM supports this by passing in the View object in OnViewAttached or OnViewLoaded . Override one of these which best suits your needs and capture that instance of your View . Then you can access your FlexGrid by name . I will edit this response with some code . Comment : Skipped over your actual question in that comment -- it does not appear to be possible according to their documentation and rumblings on the internet . This is a fairly common issue with datagrids unfortunately . Comment : I tried it see my updated question but because of some reason it didn t work . I wonder why.. . Comment : @DavidShochet Try OnViewLoaded the columns might not be visible yet a requirement for this method to work ." ] }

The problem is that when clicking the banner with text OPEN the app cannot be opened . Here is the code for the click : .. . .. . If I get rid of the GA code it works fine : .. . .. . The reason I put open in hitCallback is to make sure GA sends out the hit because open will redirect to another page . Can you help me .. . Answer : Alex from Branch.io here : .. . .. . The Branch deepviewCta function works on iOS 9+ by triggering an automatic redirect to a Universal Link URL which opens the app and then going to a fallback URL if that fails . But Apple is very specific about the situations in which a Universal Link is allowed to launch the app including things like how long of a pause is allowed before redirection . Of course these restrictions are not public so all we can do is guess . My suspicion is that putting the deepviewCta function inside a GA callback is falling outside of Apple s rules so the app never opens and you are instead being sent to the fallback URL . I can think of two options here : .. . .. . 1 . You can build some way to trigger the GA and Branch functions separately so that they don t conflict with Apple s requirements . 2 . We actually have a brand new one-click integration with Google Analytics which you can read about here https : branch.io data-integrations and here https : dev.branch.io third-party-integrations google-analytics . If you set that up you ll get all Branch-related events automatically instead of needing to manually collect link click data .

Answer : Alex from Branch.io here : yes this is definitely possible It s called deferred deep-linking and in fact it s one of our main features . Any data you attach to the link when it is created will be retrievable inside the app . See this guide https : dev.branch.io getting-started deep-link-routing overview for more into on how to set it up .", "Question : I have integrated branch.io https : branch.io in my app for deep-linking . Here the response that I am getting in the branch handler has a slight delay . Once I get the response I do some other processing and then decide whether to navigate to first screen or the second screen . The problem is even before getting the branch response the first screen is displayed . I want to delay the splash-screen for a while which is not good as most of the people say but I do not have any option probably . I referred to various links How can I display a splash-screen for longer on an iPhone http : stackoverflow.com questions 553336 how-can-i-display-a-splash-screen-for-longer-on-an-iphone where they suggest to add a splash view . But this is not working . I donot know for what reason . I also used NSThread sleepForTimeInterval : 6.0 But this blocks the main thread . I also used GCD which didn t help . In didFinishLaunchingWithOptions this is what I have coded .. . .. . But the first screen is appearing before getting the response from branch.io . Kindly help... . This is major problem in my app without which I cannot test anything. . Please help me.. . Let me know if I have not made myself clear. . .. . Answer : You can run webservice in main thread in didFinishLaunchingWithOptions . The splash-screen will wailt until the service finished . After that you can choose with screen will be pushed to . Remember handle the case the API is failed . Comment : Alex from Branch.io here : this should work . As a side note the API call is actually handled via our SDK which is guaranteed to return a value in every situation even when the network is out or the API callback otherwise fails . Comment : OK understood Wait until the completion block of fetching web service call self.window makeKeyAndVisible", "Question : null .. . Answer : I have Branch.io links which direct the user to my app in the iOS app-store . If the user clicks on the link then clicks Download then clicks Open from within the App Store the branch.io link data is present as expected . If the user clicks the branch.io link then clicks Download then clicks on the downloaded app from the home screen as opposed to in the app-store then the branch.io link data is NOT present . Is this expected behavior If not any idea what might be wrong Thanks Comment : Alex from Branch.io here : no definitely not expected behavior Would you mind sending in a support ticket https : support.branch.io for this so that we can debug what s going on from the back end", "Question : I was reading up on Google Invites : https : developers.google.com app-invites android guides app and also branch.io : https : dev.branch.io recipes content sharing android routing-to-content-within-your-android-app .. . .. . Google Invites seems to excel at Content Sharing providing an interface to select from Google all the people you want to send the deep link-to your app . Branch.io seems to excel at generating deeplinks and their shorturl would contain all the data needed by an app in their Embed key-value deep link metadata . Branch.io also has a built-in native share sheet but I don t think its as advance nice as Google Invites . I would like to use the Branch.io deeplinks with Google Invites interface for content sharing . What I m struggling with is to merge the two . When someone clicks on the Google Invites link the android app opens and inside the onCreate method the following code runs to intercept the intent : .. . .. . Branch.io tells android to intercept the intent in the onStart method : .. . .. . If I use both Branch.io and Google Invites which code should I use to intercept the intent that would start the android app when I click on the deeplink .. . Answer : I dropped the branch SDK into google s app invite example and tried a few things . It seems that you can t feed a branch URL into the AppInviteInvitation IntentBuilder as a deep link without the link being turned into a google deep link . You could set the message itself to a Branch URL setMessage url and possibly feed in a NULL URI for the deep link but that s a bit hackish . I tried this myself the e-mail feature half worked but texting did not . The default way to generate and share a branch link without the share sheet is as follows : .. . .. . As for which should you use to intercept the intent : use Branch.initSession for Branch links and use AppInviteReferral.hasReferral intent for google links . Intertwining the services for the point of a better share dialog is not the direction that I would take . Instead use a branch link they pass data through install faster than the Android SDK can with a custom share dialog there are many ways to build custom dialogs google around checkout github . Please let me know if you have any other questions or require additional information I m happy to help . Comment : Thanks for your help . This is useful info . Does Facebook App Invites as a content sharing mechanism integrate better with Branch.io Comment : I just dropped the FB SDK into an app with Branch . Sent out a few invites and nothing seems to be showing up for people no push notif and I m not even sure where FB houses app invites . Conversion rates for App Invites - sign-ups are notoriously bad again I would suggest a custom share dialog .", "Question : On BranchUniversalObj.showShareSheet it shows up facebook link on the top can we reorganize it to Whatsapp BranchUniversalObj.showShareSheet Screenshot http : i.stack.imgur.com xQdda.jpg .. . Answer : Alex with Branch.io here : .. . .. . You sure can When you re configuring your ShareSheetStyle object just set WHATS APP as the preferred sharing option like so : .. . .. . That will put WhatsApp at the top of the list if it is installed on the device . Comment : I am using Cordova Ionic . can you help with this @Alex Bauer Comment : @SandeshBSuvarna this is not a method we surface in the Cordova SDK . I m not really fluent on the Cordova Ionic platform but I believe it should work if you customize the underlying SDK .

Here is a fairly fresh thread discussing the No resource identifier found for attribute autoVerify issue specifically in relation to Branch.io : github.com BranchMetrics https : github.com BranchMetrics Cordova-Ionic-PhoneGap-Deferred-Deep-Linking-SDK issues 50 So maybe this will be resolved we the next build .. . Answer : My apologies for leading you astray in this issue http : stackoverflow.com questions 35870890 google-deep-linking I missed that you re developing in Meteor and after looking into things further it turns out that the Branch.io Cordova SDK is actually not yet officially compatible with the Meteor stack . There have been a couple of requests for it recently so I ll pass this along as something to consider supporting officially in future . If you do have any luck with the Cordova SDK based on the results from that GitHub issue please let me know", "Question : So i want to test an unreleased version of the app for deferred deep links . How do i do it As the changes made will not be there in the app i download from the play store after redirecting . .. . Answer : Alex from Branch.io here : this is pretty easy to do On your Branch dashboard https : dashboard.branch.io settings link under Settings - Link Settings - Android select Custom URL and put in the information requested . Alternatively you can delete the app from your phone open the link install a side-loaded build of the app directly from Android Studio and then manually launch the app . You ll still be deep linked to the correct place .", "Question : I d like to use branch smart banner because it can open app if it was installed . But i ve understood how it work . I need install ios sdk in my app and use setIdentity .. . Answer : Alex from Branch.io here : the smart banner actually doesn t require the SDK to be integrated . setIdentity is a completely separate method used for tracking individual users and isn t used at all for the smart banner . However integrating the SDK is definitely the easiest way to get things working because even without it you would still need to set up a Branch account configure all your link routing rules in the Branch dashboard and then enable Universal Links in your app if it s iOS . Since that is 90 of the SDK set up process you might as well do the whole thing so you can also take advantage of things like install attribution and analytics", "Question : I have integrated Branch in my app to keep track of my referrals . But I am confused how to show the user his referrals inside the application . Kindly help . .. . Answer : Alex with Branch.io here : you can use the View Credits function to show the total number of credits available for the current user : https : dev.branch.io features referral-programs guide android viewing-credits . If you are wanting to show a list of all users who have been referred by a given user that isn t a built-in function .

Clicking on a Marketing link or banner opens up the App Store via Safari every time .. . Then I go to my app manually and if I scroll thus refreshing the output on Xcode debug panel I can see the link details coming from Branch . Seems the link is making it to the app but in a deferred manner after the redirection to the App Store is happening .

We are using iOS 9.3 and Xcode 7.3.1 .. . Our app has been set up with the proper branch.io settings key schemes and URLs . Any ideas would be appreciated . Comment : Have you create URL schemes .. . Answer : This can happen if you by any chance tap the bnc.lt link at the status bar of your iPhone while the app is running . Once you do that the links will always redirect to AppStore . Try long-tapping the deep link and in the menu that pops up choose Open in your app . Comment : Thanks I read that but this is not the case . Long-pressing doesn t give me the option to open in app .

Answer : I encountered the same problem in my custom view and instead of decoding the bitmap from a resource I had created the original bitmap and the masking bitmap from the scratch via canvas.draw methods since both the original and mask are basic shapes .

Answer : Dear stack-overflow community .. . .. . I have a problem concerning the mask property of a CAShapeLayer in iOS Swift . What I am trying to achieve is an eraser that erases parts of a image-layer by masking it . The problem comes in when I try to invert it . I found some good answers on inverting a path but these were only useful when using a filled path . What I try to do is stroke a path and use the inverted one to mask an image . The line width on the stroke should by around 30.0 so it looks like an eraser . I tried different things . My current version looks like this : .. . .. . 1 . Create a CAShapeLayer which holds the path of the eraser-stroke .. . 2 . Set the fill-color of the layer to nil .. . 3 . Set the stroke-color and line width .. . 4 . Add the layer as the mask of the image-layer .. . .. . This is working fine but it only makes the parts of the image visible that are within the stroke . I want to do it reversed . I thought of a black and white mask but this does not work because the mask is delivered through the alpha channel . Does anyone has an idea how to solve the problem", "Question : I ve seen similar questions but haven t found workable answers . I want to mask a UIView using a grey image need to convert to alpha scale for masking . The UIView has background . It should be easy to mask an image but I want to mask any UIView . Any clues will be appreciated . .. . Answer : I ve been working on this problem for a couple of hours and have a solution that I think will do what you want . First create your masking image using whatever means you see fit . Note that we only need the alpha values here all other colours will be ignored so make certain that the method you use supports alpha values . In this example I m loading from a .png file but don t try it with .jpg files as they don t have alpha values . Next create a new layer assign your mask to its contents and set this new layer to your UIView s own layer like so : you should find that this masks the UIView and all its attached subviews : .. . .. . With this done you can set the UIView s background colour to whatever you like and the mask will be used to create a coloured filter . EDIT : As of iOS8 you can now mask a view simply by assigning another view to its maskView property . The general rules stay the same in that the maskView s alpha layer is used to determine the opacity of the view it is applied to . Comment : Thanks for your answer . The problem is that I only have images with grey scale alpha 1 for all points . I want to convert the grey scale image to an alpha image . Do you have any idea Comment : Well the best way to do it is to take it into an image-editing suite like Photoshop and do the conversion there . The alternative would be to do it programmatically by making a new image context then going through pixel-by-pixel on the old image reading the grey component and converting that into the alpha component for your new colour before plotting it into your new image . This is laborious and a waste of time though as you d use less processor time by doing it in a paint package . Comment : In photoshop this is easily done : 1 create a new layer 2 fill a portion of it with black 3 give it a layer mask 4 past your greyscale image into the mask . Black transparent White Opaque greys are varying degrees of transparency . 5 Apply the layer mask right-click on the mask itself in the layers panel and click apply layer mask 6 crop out the portion of the layer you need .

How could I do this and then translate it to a CGMask I know this is a complex question so any help is appreciated . Thanks . .. . Answer : There are three reasons pixels will-change from one iPhone photo to the next the subject changed the iPhone moved and random noise . I assume for this question you re most interested in the subject changes and you want to process out the effects of the other two changes . I also assume the app intends the user to keep the iPhone reasonably still so iPhone movement changes are less significant than subject changes . To reduce the effects of random noise just blur the image a little . A simple averaging blur where each pixel in the resulting image is an average of the original pixel with its nearest neighbors should be sufficient to smooth out any noise in a reasonably well lit iPhone image . To address iPhone movement you can run a feature-detection algorithm on each image look up feature-detection on Wikipedia for a start . Then calculate the transforms needed to align the least changed detected features . Apply that transform to the blurred images and find the difference between the images . Any pixels with a sufficient difference will become your mask . You can then process the mask to eliminate any islands of changed pixels . For example a subject may be wearing a solid colored shirt . The subject may move from one image to the next but the area of the solid colored shirt may overlap resulting in a mask with a hole in the middle . In other words this is a significant and difficult image-processing problem . You won t find the answer in a stackoverflow.com post . You will find the answer in a digital image-processing textbook .

Is there something wrong with my code or it s another problem Any help whould be appreciated . .. . Answer : You haven t provided an example of what your original JSON response looks like but I am guessing it is not valid JSON . dojo.xhrGet actually uses eval when handleAs is set to json which will by definition be more permissive than a strict JSON parser . dojo request on the other hand uses JSON.parse if available which expects JSON to be well formed e.g . all keys are quoted strings all strings use double quotes . Try pasting one of your JSON responses into http : jsonlint.org - if it doesn t validate there then it won t validate with dojo request . The reason dojo.xhrGet uses eval even though it s potentially unsafe is that it was written prior to widespread JSON.parse support and changing it would have broken backwards compatibility - in other words even without switching APIs developers would run into the problem you re running into right now . Edit : The JSON provided in the question now is valid and works with both the old and new APIs . Comment : The question is why is the old syntax working perfectly with my json data and not the new one I ve already passed my json to jsonlint.org http : jsonlint.org and jsonformat.com http : jsonformat.com too and it was not validated because it was missing the double quote wrapping inside keys but I don t think this was the problem because even when I corrected it it still doesn t work . Comment : Can you edit your question to include the corrected JSON or a subset of it if it s long The invalid JSON likely is the problem since as I explained the old API was more tolerant due to how it processes the data . It s the only thing that easily comes to mind given that everything else in your scenario remains constant . Comment : Thanks for your response I included a subset of my json data as you requested .

I have used this with Bobo and appengine and it works well . Comment : Thanks that looks like a better way of doing it although now I m stuck in a different way.. .

Please tell me how to understand authentication in Turbogears and fix it to fullfill all the requirements in clean way Thank you in advance . UPDATE .. . .. . Please provide solution for TG 2.2 as upgrade is not possible . .. . Answer : I suggest you to upgrade to TurboGears 2.3 more recent versions support an authenticate method in ApplicationAuthMetadata which makes easy to provide custom check of username and password validity . Standard ApplicationAuthMetadata.authenticate implementation looks like : .. . .. . If you cannot upgrade TurboGears you must implement a custom repoze.who authenticator which is a bit more complex . You can find some documentation on it at http : turbogears.readthedocs.org en latest turbogears authentication.html Comment : Thank you for your reply it means that authenticate method is not there in version 2.2 that I cannot find it Maybe possible to use AuthenticationForgerPlugin class in 2.2 I m not sure about upgrading gearbox is not a problem but I m using sqlalchemy-migrate with sqlalchemy 0.8 well as I have fixed one problem in it using postgres everything working fine.. . Anyway still don t know how it is really working as I m missing any proper documentation in 2.2 as well in 2.3.. . repoze.who don t tell me much in way using in TG.. . Any idea. . Comment : Gearbox has sqlalchemy-migrate still available through the sqla-migrate command I really suggest you to try upgrading it makes a lot easier to do what you need .

Password reset works but they still can t log in . Repoze.who is not logging anything at all so I don t know what s up . The weird thing is I can use the REST API with the api-key for the user obtained through paster and get a response . .. . Answer : This is very tough to answer without more information . There is a real possibility that the password is somehow being submitted wrong . One suggestion would be to reset the password from the command-line with a specific password and see what happens use paster user -h to see options for managing users from command-line . Comment : I ve tried that but I think I ve narrowed down the problem to an issue with WSGI it works properly if the page is served via ckan serve . I m using the standard configuration that comes with the package except with the port value changed to 80 and ServerName changed to my FQDN Comment : Are you proxying the app You may need to make sure credentials are forwarded appropriately .

Anyone have tried it and or knows something else Comment : How about you test it And what something else are you looking for Authentication framework How about OAUTH LDAP MySQL backend Comment : thank you of course I m going to try it but maybe you didn t have clear what a framework is . Comment : Perhaps you re not clear what a framework is a buzzword referring to a general purpose library for a group of functions code that can be re-used and adapter in order to achieve a desired software product . In other words an API for an authentication mechanism and there s plenty of them they are called OAUTH and LDAP for instance they are frameworks on which you base your authentication and there s plenty of API modules for them .

Answer : I think what you need to do is to setup a post login handler action when you setup the middleware . In that action you can then check params set a session var etc . I had to hook into here in order to create a message to the user that their login had failed . I check for a login failed param on the login form .

I started out using the repoze sql quickstart plugin : http : code.gustavonarea.net repoze.what-quickstart .. . .. . I then ripped out their setup sql auth and modified it for our own needs since we do both SQL and LDAP auth in our apps . Go make sure to look at the plugin source for setup sql auth and go through it until you really understand what it s doing . and since you asked on middleware config.. .

Answer : Multi language is your solution here because you are sharing product and administrators webmasters . The module domain access https : www.drupal.org project domain will give you what you need in term of domain-name management . Multisite does not share configuration so if you want to add something to all domain you will have to configure it 20 times . And if you need to add some modules for only 1 domain you can use Context https : www.drupal.org project context to specify your rules of display . If I were you I will go with D7 because there is lot more stuff available right now but the migration will be hard if you think about migrate to D8 .

Answer : I don t have any experience crowd-sourcing translations but my advice would be to find some dependable freelance translators in your target languages check out Proz.com and keep going back to them every time you have new content . Application UIs are notoriously difficult to localize because of lack of context in the resource files and so you want someone who understands the application and is able willing to test the localized version . Each of the localizations will undoubtedly reveal i18n bugs as well so there is likely to be a bit of back and forth the first time around . I guess my point is that you don t want arms-length relationships with your translators they should feel like an extension of your team . Anyway bravo for internationalizing your application .

Once completed translations the translator can export the translations a resx file to add to a project and also as an excel file for record purposes . I am new to C and hence am not sure if my strucute is correct i have designed in such that a dll is inserted into the .exe during compilator and then using this dll the translation application can extract the string .

Hence the nead for context thats why the app . So she can visually translate the strings . .. . Answer : I think you can t find a general solution to your problem with the texts that may appear in the textbox . Here is why : .. . If the texts are in the resource file you could read them but you still don t know where they are used . You would need to do a complex analysis of the source code to know where the text is displayed . Just imagine this little scenario : .. . .. . GetCorrectText could look like this : .. . .. . Resources.ConnectionState might be The connection is in the state 0 . Its a simple example but you would need to know or extract a lot of things : .. . .. . 1 . The text property of the TextBox class is the string that is shown to the user .. . 2 . The Method GetCorrectText returns the text so you need to parse it . 3 . The Method string.Format returns the text . Now you either would need to hardcode that for string.Format it should use the first parameter as the text that is displayed or you would have to parse string.Format to learn that fact . The example shows something else : You wouldn t be able to translate the whole string that is being displayed because part of it is the name of the enum value . What I want to show you is that you need to make trade offs .", "Question : null .. .

Answer : I have no idea about tranlation systems but such functionality -- custom translations for specific words -- will be offered by any commercial system I guess . It is even possible with google-translate https : translate.google.de by clicking on the book with the star on cover . As a trivial non-invasive method you could for each goal-language make up a dictionary the required terminology in the form word-as-is-translated word-as-should-be-translated where you have an N : 1 relationship in one language multiple word-as-is-translated should be mapped to one word-as-should-be-translated . The words word-as-is-translated thereby depend on the actual translation system . After preparing those dictionaries you can simply search the translation result for those words and replace them with the desired words .", "Question : I once saw a free translation management software that was used to publish the original software texts and allow translation to other languages in a collaborative way .

Answer : I am working on a .Net software product that consists of multiple applications of various sizes and dozens potentially hundreds of assemblies . Everything must be translated into several languages . Whereever I look the suggested way to localize strings in .NET is to create satellite assemblies with resource strings . Of course all those examples simply show one assembly and how to make localization work technically . My problem is that in practice I don t see how this should scale to a large set of assemblies . If i simply duplicate the approach for each assembly I end up with a really big number of satellite assemblies to maintain and deploy and I have to keep track of one and the same string translation in every assembly that requires it . Everytime a translation changes I have to locate all uses of this string throughout all my assemblies and modify it . Everytime I need to update my translations I need to extract everything from the multitude of resource files send it to the translators and then spread their results again to the correct resources . This can be done of course and I assume some of it can and must be scripted . However it doesn t strike me as especially smooth and efficient . One alternative I can think of is to create a dedicated translation assembly with satellite assemblies that serves as a central repository for localized strings . All translations of all strings of all assemblies would go there and it would be referenced by each and every assembly in turn to spit out the translations . This seems to make maintenance a lot easier but of course this central assembly with its enormous set of resource strings would have to be deployed along-side even the smallest of my applications which actually would need only a tiny fraction of them . Moreover this assembly would have to be frequently changed by many developers which would lead to a high risk of conflicts . My question is : .. . How is the approach of localization via satellite assemblies supposed to scale to large software projects with many assemblies What are the suggested strategies and best practices Comment : To quote MSDN http : msdn.microsoft.com en-us library 5839we2z 28v vs.110 29.aspx The common language runtime supports a satellite-assembly resource model that separates an application s executable code from its resources . For more information about implementing this model see Resources in Desktop Apps http : msdn.microsoft.com en-us library f45fce5x v vs.110 .aspx . emphasis mine As such why would you need to update your code if a translation changes After all the resource name can and should stay fixed across locales.. . Comment : No need to update code of course . What I meant is : There are numerous strings that are repeatedly used throughout large parts of the application . If each assembly has its own translations of these strings in its own satellite-assembly effort is required to keep those translations in sync . Comment : Sounds more like you want to refactor consolidate your assemblies or use tools to build the duplicate resources . Of course a good case study of how it can work is the .Net framework itself . Comment : Are you saying that a situation with translations shared by multiple assemblies should be avoided I see that this would of course resolve the problem . I assume this is also the way the .Net framework does it . However If I do that I end up with one humongous assembly . This is just not possible in my case for various reasons .

You could search for the filenames inside the directory or use another tool like cflow to see what functions are called from the file . You can t display that information because ctags doesn t care about . Ctags is a tool to map the definitions of functions defines etc .

TagList and TagBar against a racket file http : i.stack.imgur.com yEaIr.png .. . .. . From what I understand Racket is a rebranding of some Scheme derivative . If it doesn t deviate too much from the norm adding this line in your .vimrc may help : Comment : Thanks for answering . I d not actually found TagBar and interestingly enough it just worked with my .ctags file which I added to as I tested it . Unfortunately while it does work it doesn t display tags from multiple buffers at once at least I didn t see an option for it . I d like to see if I can get the problem fixed but it is good to know I can work around it . Thanks .

Answer : Taglist only supports exuberant-ctags tool not GNU ctags or the Unix ctags see the FAQ http : vim-taglist.sourceforge.net faq.html . I use tagbar http : majutsushi.github.com tagbar instead of it . Comment : special thanks for tagbar suggestion I didn t know about it seems to be much better taglist Comment : Many thanks for this Installed it and it works straight away .", "Question : I ve recently started using racket and one of the first things I ve done has been to try and get the vim TagList plugin http : vim-taglist.sourceforge.net to work with it . However it doesn t work in the slightest . I can open racket files and the TagList window will be as blank as-if I had opened a text file .

About TagBar .. . .. . I had not seen TagBar before people had suggested it . Interestingly enough it just worked with the changes to my .ctags file . Unfortunately I ve not found a setting for showing the tags from all loaded buffers the way TagList does so I would prefer to use TagList . I d post comparison images but I don t think its going to let me as a new member . As per romainl s suggestion I can set the vim filetype to scheme and it does work . This however only seems like an 80 solution when the documentation according to the extending pages seems to suggest that what I have should work . Perhaps I should be looking at filing a bug report . Thanks again Comment : Do your settings work when you use ctags directly from the command-line If not it s not a problem with TagList or Vim but with your regular expression . Comment : Does this --langmap scheme : .rkt work when ctags is used directly Comment : try tagbar looks better than taglist Comment : @locojay Indeed it does but it does not as far as I can see display the tags of multiple buffers at once . Comment : @romainl yes to both questions . I m editing the post to provide more details . .. . Answer : I ve been struggling with the same issue though for xslt files.. . My solution was found by poking around in taglist.vim whereby I added a line for .. . .. . try doing a search for the s : tlist def parts of the Vim code and put in something which looks sensible . There s a similar mechanism within Tagbar .

Do I have to generate a separate tags file by running say ctags .f90 in order to be able to use Ctrl+ .. . Answer : Yes you need a tags database usually created by running ctags or an equivalent external tool to use the tag jump search functionality of Vim . As Vim is a general-purpose text-editor it does not possess any knowledge about individual languages and instead delegates in true spirit of Unix s do one thing well mantra this to an external resource . PS : There are plugins like easytags.vim http : www.vim.org scripts script.php script id 3114 that automate the process of tags generation and update . Comment : Thank you . Thus taglist is just an addition to the still required : ctags invocation either manual or automated via easytags The actual purpose of taglist remains unclear to me . Comment : What exactly do you mean by taglist The : tag.. . commands or the taglist plugin which ought to invoke ctags automatically Comment : vim-taglist.sourceforge.net http : vim-taglist.sourceforge.net Comment : Indeed vim-taglist invokes ctags but doesn t keep the tags file which is necessary for Control+ to work .

Taglist is working nicely without the need to generate the tags file myself I can see the tags of the current buffer in the tags window and go to any of them etc .

What should I do to be able to use C- Comment : You might want to use plugin Indexer : goo.gl kixRn http : goo.gl kixRn . It provides painless automatic tags generation for the whole project s and keeps tags up-to-date . Check my another answer for some details : goo.gl pG9OP http : goo.gl pG9OP Comment : thanks Dmitry I will try that for sure .. . Answer : TagList is a third party plugin completely separated from Vim s C- and related commands . Because it doesn t generate a tags file or even uses a tags file it operates in its own bubble . C- is a native Vim command that uses a tags file that you need to generate with a command like : ctags -R . and that you must make sure it is known by Vim . Comment : understood thanks . So the question is now is there a way to tweak taglist to use C- Comment : TagList provides a list generated using ctags of the symbols present in your file that you can use to navigate in your code with CR or a mouse click . C- is totally unrelated to the TagList plugin and is used to jump to the definition of the symbol under your cursor . Using C- in the TagList window makes no sense because there is no code there thus no symbols and no reason to use ctags and C- there . Comment : Anyway to extend standard vims tags with TagList So I can do both navigation via cr in window and c- while cursor on function Comment : @FelikZ you can do both already if you have both a tags file and TagList running . Ask TagList s authors for that feature .", "Question : I m using a taglist plugin for a few days and now I tried it with Javascript but in Javascript it shows only partial information or no information .

Do you know how to correct this problem thank you Comment : There s a missing between namespace name and a missing after the last and the last is not allowed here in JavaScript . Comment : @romainl Syntax is OK . I have this problem with all javascript files . .. . Answer : Did you try TagBar http : www.vim.org scripts script.php script id 3465 It s a more modern take on the same idea which works better with JavaScript and even supports jsctags . taglist on the left tagbar on the right http : i.stack.imgur.com Lie5A.png .. . .. . TagList on the left TagBar on the right . TagList doesn t work because Exuberant ctags the program used by TagList to index your code is not very good with JavaScript especially the modern stuff with callbacks closures and self executing functions . On the other hand TagBar uses jsctags for JavaScript if it s available . Jsctags is made with modern JavaScript in mind and as such works a lot better . Compare these tag files generated against the following code based on your samples : .. . .. . Output of ctags . : .. . .. . Output of jsctags . : .. . .. .

So basically there are two ways to solve your problem : customize ctags or use tagbar+jsctags . Comment : It shows correctly functions in namespace but still has problems with many functions . I will edit question . Comment : There are too many in your sample . But it doesn t really change anything . See my edit . Comment : Is jsctags still available to download from somewhere Comment : Yes you can download it from its official github page https : github.com evilpie jsctags .

This will work if 1 taglist or tagbar is on the leftside 2 you open only one a window at first then press CTRL-e . You can open other windows then .

Answer : As far as I know the Taglist plugin shows only the variables which have file scope . It does not show variables which have only function scope . For a quick test just add a variable of any type at the start of your source file save the source file set cursor into the taglist window and press u to update taglist .

You are the first person who is telling me that they don t want to use a great editor because of its looks .

The experience so far has been fantastic but I m stuck when it comes to Javascript . The ever-popular taglist utility using Exuberant Ctags has been great for everything but Javascript .

Help appreciated .. . Answer : I ve not used javascript or taglist much but looking through : help taglist-extend it looks like your definitions listed above rename the javascript output to js so you ll probably need something like in your vimrc : .. . .. . This is assuming that the ctags kind is f for function and m for method . Have a look at your tags file and see what the kind column looks like . By way of example my C code tags file includes this line : .. . .. . This is a define of a symbol ADC CR1 AWDCH 0 which is in the listed file at line 2871 . The d is the ctags kind for a defined name . Hopefully that will give you enough to get you going . As an aside I m not sure whether the override will work correctly so it might be worth naming your file myfile.mjs and changing your langmap to js : .mjs until it s working properly . Then at least you ll know whether your problems are associated with misidentification of files or the actual parsing ." ] }

See my latest edit .", "Question : I m using phoenix controllers to receive data via REST calls . So an iOS app could send the events for each user and based on the event I need to calculate the score points and send it back to the user .

What is a good pattern to do calculation Calculate could be bunch of database queries to determine the score of that event . Where should this calculation happen Background workers GenEvent streams within user-specific GenServer I have supervised GenServer per user .

REST APIs does not get give any response back other then 200 OK . What about GenEvent .. . Answer : I would look at Phoenix channels http : www.phoenixframework.org docs channels tasks http : elixir-lang.org docs stable elixir Task.html and GenServer http : elixir-lang.org docs stable elixir GenServer.html . Additionally if you would like to manage a pool of GenServer workers to do the calculations and maybe send back the results for you check out Conqueuer https : hex.pm packages conqueuer . I wrote this library and it is in use in production systems for my company . It is uses poolboy https : hex.pm packages poolboy which is probably the most pervasive pool management library in Erlang Elixir . Admittedly I do not fully understand the requirements of your system but it does not seem to me GenEvent has a place in your requirements . GenEvent is about distributing events to one or more consumers of events . So unless you have a graph of processes that need to subscribe to events being emitted from other parts of your system I do not see a role for it . Comment : I ended up using Conqueuer library . Comment : Is it possible to get the instance of the worker I m using RethinkDB elixir client driver which requires connection to be initialized as defmodule FooDatabase do use RethinkDB.Connection end So I defined my worker in conqueuer as FooDatabase . Comment : Conqueuer does not expose a way to gain access to a worker as there is a pool of workers . You should just pass the work to the pool and it will handle it for you depending on your naming something like : Conqueuer.work : foo databases some args here . If you are trying to gain access to a specific worker from your pool of workers I would question your design . Do you actually need a pool Do you actually need to access a worker directly", "Question : I am receiving an Invalid CSRF token error when trying to update or create a record . I am using Elixir v1.0.3 Erlang OTP 17 erts-6.3 and Phoenix v0.8.0 I think I am not sure how to check Phoenix s version . I am creating a web app mostly following the Phoenix guides and the Elixir Dose Jobsite Example resources .

Following the advice given in the error I added x-csrf-token : csrf token to the action . edit.html.eex : .. . .. . but I receive the following error : .. . .. . As far as I can tell being new to Elixir Phoenix and HTML action is essentially a path and any parameters I place in it will find their way back to the application .

I am not sure exactly where the csrf token comes from so I do not know how to reference it or perhaps I am doing this completely wrong . Any ideas would be greatly appreciated . .. . Answer : To see the version installed run .. . .. . Which shows you which phoenix you have in the deps directory . Also if when you upgrade to phoenix 0.9.0 things have changed due to updates to Plug.CSRFProtection the CSRF works differently using cookies instead of sessions . From Phoenix changelog for v0.9.0 2015-02-12 https : github.com phoenixframework phoenix blob master CHANGELOG.md v090-2015-02-12 .. . .. .

To access the token s value grab if from the cookie which on the server-side looks like .. . .. . So for your code would look something like .. . .. . Now for completeness I needed the updated CSRF for requests built purely client-side so here is how I accessed the cookie within javascript using JQuery cookies for easy access . You should be able to see the value in your browser by running the following .. . .. . Which might return something like .. . .. . Note in the above the space which in phoenix was being url encoded to + which was still causing the CSRF to fail . Now is that a bug in Plug or simply something to be handled I am not sure so for now I am simply handling the + explicitly .. . .. . With access to the CSRF token we now just need to add the x-csrf-token to your request header thank you ilake https : gist.github.com ilake 3656567 . Here is the code to make it work with an ajax call work fill in the url and data and response accordingly . Note that you could send back the csrf token as parameter as well but I prefer the above and it feels cleaner to me . Final note I didn t have enough reputation points to properly post a link-to jquery-cookie but it should be easy to google . Comment : Thank you for the detailed response . It turns out I am running Phoenix 0.8.0 so the code below works but you have saved me a big headache when I upgrade to 0.9.0 Comment : Thanks again @a4word I upgraded to Phoenix 0.9.0 and changed the template to get the token from the cookie . However strangely enough it seems to work but I am still getting a Invalid CSRF Cross Site Forgery Protection token error . The token is ne0GATpoc EW6jbIbC7tmfkAWl4qb1opTPWmmfYFTRY no spaces and the template creates a url POST config directories 9 x-csrf-token ne0GATpoc 2FEW6jbIbC7tmfkAWl4qb1opTPWmmfYFTRY 3D I have no idea why Plug.CSRFProtection does not like it . Do you know or should I open another question Comment : I changed the name of the token in template from : x-csrf-token : Map.get @conn.req cookies csrf token to : csrf token : Map.get @conn.req cookies csrf token and now it works . Comment : That s right . See in your POST that the x-csrf-token is added a param on the URL but it needs to be an HTTP header .

They are naming-conventions usually applied to the end of function name and are not any special syntax . - Will raise an exception if the function encounters an error . One good example is Enum.fetch http : elixir-lang.org docs v1.0 elixir Enum.html fetch 2 It also has a same Enum.fetch http : elixir-lang.org docs v1.0 elixir Enum.html fetch 2 which does not raise exception .Finds the element at the given index zero-based .

The problem with this approach is that you can t use context : key directly in a pattern-matching you ll get a compile error cannot invoke remote function Access.get 2 inside match . Because of this you still need an extra step to assign context : key to a variable each time you want to use the context variable for a pattern match not so DRY .. . .. .

I was wondering if it s a good idea to use them for this purpose since so far I have not seen others doing it . What do you think .. . Answer : So first thing I would probably switch to Elixir 1.1 or 1.2 . There are map improvements there . You linked to the 1.0 docs which are somewhat dated . Second thing is you can use pattern-matching to grab the variable from the context . Here s an example from the 1.2 ExUnit docs http : elixir-lang.org docs v1.2 ex unit ExUnit.Case.html : .. . .. . The second argument to the test is the context but instead of accessing the pid member you re matching out the pid . Now you can use it just like a normal variable . You can pattern match on it and pin it . It s more than DRY you re declaring exactly what bit of the context you re depending on . It s more concise and more explicit . I really recommend reading the 1.2 docs as they have a ton more examples . Comment : Actually this happened when I was using 1.2 .

I m just lost.. . Thanks for the feedback .. . Answer : Take a look at Plug.Router docs http : hexdocs.pm plug Plug.Router.html for how : match and : dispatch works . : match will try to find a matching route and : dispatch is going to invoke it . This means Plug.Static in your setup will only be invoked if you have a matching route in your router which doesn t make sense . You want plug Plug.Static before everything . Remember plugs are just functions that are invoked in the order they are declared . Other than that your Plug.Static setup seems ok . Your current configuration will serve assets at pub meaning pub index.html will look for priv static index.html in your app .

Answer : OpenSolaris includes just the Java Runtime JRE out of the box - developer tools like compilers for C C++ Java don t fit on the LiveCD so are installed from the package repository . pkg search javac will show the packages available with the javac command - if you re using the latest development builds it will be in the developer java jdk package or jdk for short so you could install with pfexec pkg install jdk . On older builds like the 2009.06 stable release the package name will be something like SUNWjdk instead .

SUNWj6dvx WUNWj6dmx SNWj6rtx then its saying Installation of SUNWj6dvx was successful however javac results with no such command again can you help please Comment : Since pkg search identified SUNWj6dev as the package name the command would be pkg install SUNWj6dev the pkg : is optional . Also 0.91 is a very very old developer build it was part way between the 2008.05 and 2008.11 stable releases - seems strange to be using if you just installed it .

I want to do the same in OpenSolaris Indiana . I see staff group having the same gid in OpenSolaris as wheel in Linux for example Fedora or CentOS . .. . Answer : There is no wheel group or equivalent under these OSes although nothing forbids to create one and configure sudo to allow passwordless root commands . A more Solaris style alternative might be to grant these users the Primary Administrator profile and or grant them the root role . Not sure you will avoid a password prompt though .

The Boost : : MPL Documentation seems to suggest that sun compilers are not supported http : www.boost.org doc libs 1 5F41 5F0 libs mpl doc tutorial portability.htm the document was last updated in 2004 . Boost s top level documentation seems to suggest that the sun compilers 5.10 onwards are supported -- I guess this is a general level of support or does this include MPL . Does anyone have any details on the state of the C++ conformance of the sun 5.10 compilers I could always compile using GCC . Comment : Boost : : MPL seems to have an extensive set of unit tests you can try to run them under your compiler . This should give you the most recent status of support regardless of any documentation . Comment : What liori said but if you are looking to make sure that your environment is working as expected you would have nothing to compare it to . You should find some documentation about what is to be expected then also run the unit tests and see if they are what the document projected . Comment : Thanks guys I have done some prototyping with the MPL libraries and they seem to work fine with the few constructs I tried . However the code ends up looking nasty . So I think i ll move into generative-programming probably using Lua and targeting the C++ with STL and possibly the simple BOOST libraries . .. . Answer : I guess since an exact answer has not been provided I must post one myself . opensolaris 2009.06 and boost-1.4.1 seem to work well . The . bjam picks the right switches and boost : : mpl seems to work well with the sun compiler present . So as far as I can tell the mpl documentation on compiler support is quite outdated ." ] }

Answer : Edit : I have resolved the issue by removing ob clean calls from PHP script which I previously needed on my local server in order to avoid returning anything prior to the actual PDF data . Everything works as it should now . It still bothers me though why did ob clean mess things up on the shared-hosting server but there were no issues on the local server Pre edit : .. . .. . I have a PHP script that : .. . .. . 1 . Takes a piece of JSON data .. . 2 . Decodes the data to a PHP array and.. . .. . 3 .

The issue I have is not present on my local server WAMP stack PHP 5.5.12 everything works great . On the shared-hosting server though I get a scrambled response the issue is illustrated in the image provided . The data is of course unusable .

The mPDF library is working fine as I ve tested some of the files from example folder and all of them were processed with no issues at all but without any AJAX involved .

Setting both client and server encoding headers to utf-8 - no change . 2 . echo -ing the pure HTML data prior to processing it with mPDF - the data was fine all of it was there none was scrambled . 3 . echo -ing string before converting it to base64 - the issue persisted . 4 . Processing a simple p Hello world p string with mPDF - data was scrambled . 5 . Trying different headers on the server-side commented out in the code provided .

Comment : As explained in my answer to C ItextSharp Fontawesome Icons currency - PDF http : stackoverflow.com questions 30440982 c-sharp-itextsharp-fontawesome-icons-currency-pdf you re using Windows-1252 encoding for symbols that probably require UNICODE .

You see that some characters are missing in some screen shots because the wrong encoding is used . There is a difference between the double-byte Unicode character uf0d6 and the two separate single byte characters with value 240 0xF0 and 214 0xD6 . Maybe that s causing your problem . Comment : Sorry but I don t really understand . what do you suggest I do Comment : You could start to learn more about fonts and encoding . Show us the PDF . Maybe you re not even using the Fontawesome font chances are that it doesn t show up in the Fonts panel under Document Properties . .. . Answer : Encoding issues aside this could be a couple of things . Firstly you need to integrate FontAwesome with your MPDF installation . Secondly you need to consider how you re speficiying the glyph in HTML . Installing FontAwesome in mPDF .. . .. .

Answer : The fact that you see a regular o followed by an unknown character strongly suggests the second character is a single non-spacing diaeresis not available in the font you are using . Checking the character sets of DejaVu Sans and Open Sans proves my hunch is right . DejaVu Sans does contain a COMBINING DIAERESIS U+0308 : . OpenSans does not .

I still would appreciate knowledge of what leads to this function being called . Comment : AFAIK There is no CoUnitializeEx . Can you post a screenshot CoInitialize Ex CoUninitialize exist to register threads with the COM library . I d assume that the main thread is always registered with the library even if you don t supply a thread attribute STAThread MTAThread on the main entry-point . Comment : CoUninitializeEx also seems to be calling CorLaunchApplication which calls TranslateSecurityAttribute which calls GetAddrOfContractShutoffFla.. . which calls SetCounterName which calls WaitForSingleObject which calls WaitForSingleObjectEx . A lot of these functions seem COM centered but I m not directly using any COM objects that I know of . The only standard-library I m using is System.Math . .. . Answer : CoInitalizeEx and CoUninitialize are pretty core in Windows programming . They respectively initialize and shutdown COM on a thread . The CLR calls these functions automatically before and after a Thread runs . It is pretty hard to avoid using COM in a .NET program it is the basic extensibility model for native Windows code . Quite invisible thanks to the many wrapper classes in the .NET framework that hides the plumbing . The generic diagnostic is that you use a lot of threads . Yes expensive . The thread pool is a workaround . Comment : Thanks Hans the problem is that I m not visibly using any threads . The only thing done by the function in question is : arithmetic looping comparison memory allocation double s via new double and calling Math.Log . Does the call to Math.Log somehow create a new thread Comment : No it doesn t . Not sure what you are looking for it you enable profiling of native-code then it is guaranteed that you ll see this function . Since you cannot actually change any of this code maybe you are better off just not looking at it Comment : Specifically I m looking for the types of programming that are related to this CoUninitializeE is taking up to 40 of my programs time . It shows up in some functions but not in others so it s not just a constant overhead on calling functions . Since memory allocation and Math.Log are the only native calls I seem to be using I was wondering if it was related to one of these . I.E . if it s related to Math.Log then I could try and optimize my function to call Math.Log less . Comment : You are getting garbage profiler results . Not just the extra E . CoUninitialize is only called at thread exit . Get another one good ones cost money ." ] }

Also is it true that boost : : phoenix is a superset of boost : : bind booost : : lambda libraries Comment : C++11 also has lamba built-in to the language . Latest Visual Studio and g++ support it . You should add that to the mix Comment : I think the point here is to differentiate various approaches provided by boost for binding not enlisting all lambdas available . Comment : The answer to the duplicate you linked to perfectly answers this question too . .. . Answer : I think the story is though I m not old enough to tell the whole story boost : : bind was first created to replace the hard-to-use bind1st bind2nd in C++98 and it achieves its goal and now part of C++11 . But also as last 10 years saw the rise of functional-programming style in C++ boost : : lambda pushes it so far at the time it was created that it supports a reasonably wide set of functional constructs with pure library approach in C++ . And then as I know from the news group the author of boost : : lambda and boost : : phoenix try to combine the two libraries as they deal with virtually the same problem . I guess that was the beautifully designed boost : : phoenix2 .. . .. . And then there comes boost : : proto which is a libary for writing expression-templates or I d say it s a meta-library . So the phoenix nirvana again reborn itself on boost : : proto then we see phoenix3 . I think phoenix3 is the most powerful among all above . On the other hand C++11 adds language support for lambda expression which I personally find very useful and handy . The only drawback is it s not polymorphic while phoenix3 allows creating polymorphic function objects . As a conclusion that I come with personal experience C++11 lambda expression is the choice for daily job if available . It s handy clear and compile-time friendly . Phoenix3 is polymophic very powerful very cool with the drawback of long compile-time . Comment : Good answer but two small nits . : - 1 The author of Boost.Lambda has made no direct contributions to any version of Phoenix only influence . 2 Phoenix v3 s compile times are actually faster than Boost.Lambda s if you only include the minimal required headers .", "Question : I want to be able to bind Foo.f1 s s1 without an instance of foo to create in essense .. . .. .

Questions : Is this possible If yes 1 how to achieve it 2 What s the declaration of MyFooFunc Comment : It depends on SomeOtherFunction is declared . Note that your second typedef is not a function pointer it s pointer-to-member-function PTMF which is an entirely different and incompatible concept . Wrapping everything in std : : function or std : : tr1 : : function or boost : : function would probably be the most powerful solution . Comment : There are actually two issues here : 1 binding PTMF without an instance . 2 express the result-of the bind as boost-function . For 1 I tried boost : : bind Foo : : f1 1 2 hello . That didn t work . For 2 I suspect it s boost : : function int boost : : shared-ptr Foo int . .. . Answer : The result-of boost : : bind is not a pointer to member so func1 cannot be initialized as such on the second line . The result-of boost : : bind is an unspecified type which will depend on the parameters . If you re using C++0x the simplest way to name the result-of a call to bind is to use auto : .. . .. . Another simple way not restricted to C++03 is simply to not name the result but to use it on the spot : .. . .. .

We now need to find the appropriate signature for SomeOtherFunction : again a pointer to member can t be initialized from the result-of a call to boost : : bind so void SomeOtherFunction MyFooFunc func won t work . You can make the function a template instead : .. . .. . If a template is not preferrable then you must use some kind of type-erasure such as again boost : : function . once again other boost : : function types are possible depending on details such as passing a ref-to-const as opposed to a ref-to-non-const Comment : Perfect thanks .", "Question : I have std : : map int std : : pair short float and I need to find the minimal short in this map .

Answer : Of course somebody s going to complain that this is an abuse of STL and that these are extensions not in the C++ standard Comment : Well I would complain about nonstandard extensions but as far as STL abuse goes I think it s perfectly fine : +1 . Luckily the nonstandard bits are easy to write yourself .", "Question : I have std : : map int std : : pair short float and I need to find the minimal short in this map . How can I use boost : : bind with std : : min element for this boost : : lambda .. . Answer : The map iterator will give you a pair where first is the int key and second is the map s pair value so if you had an iterator it you d want the minimum of all the it- second.first values . The min element function expects a comparison function for its third argument so you need to build a comparison function that projects second.first of its two arguments . We ll start with some typedefs to make the code more readable : .. . .. . We re going to use Boost.Lambda for its overloaded operators allowing us to use operator .

I wonder what s wrong Really appreciate . Comment : What are you trying to do with the strings in vector Comment : bind and lambda both have placeholders 1 bind in anonymous namespace lambda in lambda namespace . try not using entire boost : : lambda namespace .. . Answer : The first problem is that std : : vector : : push-back is an overloaded function in C++0x there is an overload with an lvalue reference parameter and an overload with an rvalue-reference parameter . The second problem is that the types of Standard Library member-functions are unspecified : implementers are permitted to add extra parameters with default-arguments to member-functions and they are permitted to add additional overloads of member-functions so any casting that you do would not be portable . The disambiguation example assumes that we ignore this second problem . You will need to cast the pointer-to-member-function to the correct type otherwise this won t work with a C++0x library implementation the pointer-to-member-function will be ambiguous . You ll need : .. . .. . Using the C++0x functional library the following works it should work with Boost as well if you replace std : : with boost : : I just can t test that : .. . .. .

Or for more fun : Comment : Thanks the application works but I am a little confused with this code : void std : : vector int : : const int std : : vector int : : push-back . I need to learn more about that . Comment : @user : std : : vector int : : push-back takes the address of the named member function . The part that precedes it is a cast just as-if you had said int 3.0 which casts the double value 3.0 to type int .

Answer : IIRC Boost.Bind uses boost : : mem fn for its binding to members capability . Now if you look at mem fun http : www.boost.org doc libs 1 42 0 boost-bind mem fn.hpp scroll down to the data member support part you ll see that it typedefs its result type as a const while is still has overloads of the function-call operator supporting the extraction of a non-const member from a non-const argument . It thus seems that the problem is that this confuses Boost.Bind s return-type deduction mechanism . A solution would thus to explicitly tell Bind that the result is not const : Comment : +1 Nice detective work . : - Strangely using boost : : lamba : : bind will compile without explicitly specifying the return-type .

Comment : @Carl - also notice that boost : : mem fn is easier to use than boost : : bind in this case Comment : This answer is orthogonal to the question it replaces the std : : for each loop by boost : : for each but does not tell how to use boost : : bind as argument to either .

Answer : boost : : function allows anything with an operator with the right signature to be bound as the parameter and the result-of your bind can be called with a parameter int so it can be bound to function void int . This is how it works this description applies alike for std : : function : .. . .. . boost : : bind klass : : member instance 0 1 returns an object like this .. . .. . where the return-type and int are inferred from the signature of klass : : member and the function pointer and bound parameter are in fact stored in the object but that s not important .. . .. . Now boost : : function doesn t do any type checking : It will take any object and any signature you provide in its template parameter and create an object that s callable according to your signature and calls the object . If that s impossible it s a compile error . boost : : function is actually an object like this : .. . .. . where the return-type and argument type are extracted from Sig and f is dynamically allocated on the heap . That s needed to allow completely unrelated objects with different sizes bind to boost : : function . function impl is just an abstract-class .. . .. . The class that does all the work is a concrete class derived from boost : : function . There is one for each type of object you assign to boost : : function .. . .. . That means in your case the assignment to boost-function : .. . .. . 1 . instantiates a type function impl concrete void int unspecified type that s compile-time of course .. . 2 . creates a new object of that type on the heap .. . 3 . assigns this object to the f member of boost : : function .. . .. . When you call the function object it calls the virtual function of its implementation object which will direct the call to your original function .

Comment : so is the contents of struct unspecified type ie the code in the operator function basicly generated from the arguments past to boost : : bind on a case by case bases to allow any combination and number of arguments Comment : No there are templates of operator that handle all arities and different template arguments handle the combinations Comment : In the last code block it reads : arg0 const 0 return.. . .. .

I was asking whether that is intentional or not . By your mention of ADL I wasn t sure .

Answer : boost : : bind generates a functional object which can be optimized out if it is used as argument to function-templates but boost : : function prevents this optimization just like passing a pointer to a function will prevent its inlining . boost : : function itself need not introduce more overhead than a virtual function all or call via a pointer to function .

Thanks in advance Comment : I loved the tag robots.txt you added . Comment : @KPL LuLz politeness is very important on the internet Nobody likes a pesky robot : .. . Answer : What kind of robotics are you trying to do i.e . is it a robot where a laptop or another powerful device might be an acceptable controller Or are you looking at a small true embedded robot If it s the first MS Robotics might be right for you . It uses .Net IIRC so there s a nice low entry barrier . If you wanna do something smaller maybe look at Arduino which has so much support around its platform that you ll probably find what you need . Arduino uses something very very much like C++ . Regardless of what you choose find a kit robot . I can t stress this enough . You want to spend time doing AI not getting hardware to all work correctly . If you wanna try something weird and interesting the Parallax Propeller Microcontroller is a relatively cheap arudino-weight processor with 8 cores . Might be nice for AI where thinking generally is best done in parallel .

Once the button Goto CRM is clicked the matter numbers all fields if possible are used to compile the URL for the CRM webpage . e.g . http : Casemangesyatem test9999.1.apx .. . .. . I don t know how this is achieved or what the file compiled is or how to create it any examples notes would be greatly appreciated . So how or what is used to compile the file that is location called by the regkey .. . What do I use to create this file and how do I do it .. . .. . Thanks you . This is the only site that I have found with any reference to work-site sdk . I m new to work-site sdk and would appreciate any kind of help with example code . .. . Answer : To run some custom code when a user selects your new right-click option you ll need to create a new DLL in Visual Studio to do the actions you need e.g . redirecting the user to a custom website . The worksite SDK contains some sample ICommands in VB.NET and C to get you started . The main requirement for your custom code is that it implement the IManExtLib.ICommand interface like below : .. . .. . In the registry key below the Commands value should contain the comma separated list of the ClassIDs of the ICommands you want to appear in the right-click menus at that level . For example the following value includes some of the standard entries and our custom class from above and would appear in the right-click menu of a workspace within Filesite . Comment : Hi G David I appreciate you responding to my cry for help as I don t have access to the worksite SDK I have been trying to search the web for some help you have been the first to respond again thanks you . I have found a couple of documents like MHDLL32 and the extension library which are very good if I know what I was supposed to do with them I m not a developer but I m learning very slowly lol . Can I be cheeky to ask if you have any samples or steps that I can follow to achieve this as my first project I would be very gratefully if you can get me started . Many thanks R", "Question : I am using the WorkSite COM API to open an IMANEXT2Lib.IManFileOpenDlg which is working perfectly . Clicking on the document I can retrieve the metadata such as the document name version number etc . Is there a method or technique available to read the document from WorkSite and prompt a download open through a browser The IManage.IManDocument has the method GetCopy available which will download a local copy to a specified directory but this isn t really what I m after . .. . Answer : If the clients have Worksite 8.5 or greater you can use the IWL protocol in a hyperlink to force the client to use the IWL handler to download and launch the file themselves instead of streaming it from the browser . This has the added benefit of respecting the document s permissions and checking the document out to the user so they can make amends to the file if required . An IWL formatted anchor tag in a web browser would look like the following : .. . .. . Note that this will only work if the clients have Worksite 8.5 or newer installed .

Thanks in advance Comment : I loved the tag robots.txt you added . Comment : @KPL LuLz politeness is very important on the internet Nobody likes a pesky robot : .. . Answer : Try using webots for designing the control . I found it very intuitive and friendly.. . lets you focus on your core programming logic . Hardware should start from Boebot the very basics and graduate to Arduino platforms as you gain knowledge . Try getting a Pioneer once you move to real robotics excellent sensor suite but prohibitively priced . Or try flying bots like A.R.Drone etc . It would be nice to program and will give you insight into UAVs as well ." ] }

You can take look at what is going on with the Linux boot using Boot Diagnostics and Console https : azure.microsoft.com en-us blog boot-diagnostics-for-virtual-machines-v2 . That is the way i would recommend to do first then try to upload manually . Then check if SSH is enabled - go to your VM Settings Network interfaces click on the Network Security Group name Inbound security rules . Create your 22 SSH rule . Comment : I activated the boot diagnostics and it I could see that system was indeed booted . The Question that I have is if i need to configure SSH specifically in the azure Portal OR in the VM . Comment : Awesome that the VM is OK . You should check if you have SSH endpoint configured in the Endpoints menu with the port 22 . Comment : I dont think there are endpoints in the new resource manager layout.. . I have a resource group containing the VM a NIC a public IP and a vitual network Comment : Yep .

It is the same version of mine GNU Wget 1.15 built on linux-gnu . When I execute the command for the very first time it worked very well . But now I do not see the file in my downloads . Comment : what directory are you using wget from could you specify an absolute path for the output file so you would be sure of the output location Comment : I did not specifically give an absolute path . Since I am downloading the file and gonna save it locally shouldn t it be saved in downloads Because at the very first time I could see the file in my downloads .

Comment : I see . Maybe there is an issue with the 2009 version then . .. . Answer : It s a bug in TGIFImage s LZW encoder . In some very rare circumstances the LZW encoder will output an extra zero byte at the end of the LZW steam . Since the LZW end block marker is also a zero byte a strict GIF reader might choke on this or interpret it as the end of the GIF although the end of file marker is 3B . The reason some GIF readers can handle this is probably that GIFs with this problem was common many years ago . Apparently TGIFImage wasn t the only library to make that particular mistake . To fix the problem make the following modification to gifimg.pas change marked with : Comment : This appears to solve the issue . Thank you very much Excellent answer Comment : But what happens if you call function TGIFWriter.Write const Buffer Count : Longint : Longint with a count that would make more than one call to FlushBuffer That would block the writing . Comment : AFAIR the encoder only writes a single byte at a time so it s will never become a real problem . Apart from that I agree that it smells . FNeedsFlush should be set inside the inner loop in TGIFWriter.Write instead of outside the outer loop .", "Question : I created a small form that I want to put on top of other forms when they are working .

Probably since they are running in the same thread Is there a quick and easy way to have this little form always update nicely Perhaps a quick way to make sure it s handled in it s own thread .. . Answer : Move the hard work into an actual thread of its own . See the TThread class . Display your Form normally then start the thread then close the Form when the thread is done with its work . Have the thread post status updates to the main thread asynchronously if needed such as for progress bars etc so the worker thread is not slowed down waiting for the main thread .", "Question : I created a small form that I want to put on top of other forms when they are working .

Answer : Thanx for the answer Remy Lebeau . I wanted to have to change as little as possible to the existing code though and not move existing code into threads etc .

Step 2 : Use el-get to install ecb . Do a web search on el-get emacs to find out more about el-get . The advantage of using el-get is that it will automagically take care of adding ecb to your emacs load path . BTW it seems to take a good 15 or so minutes to install ecb using el-get .

Answer : The answer is that unfortunately no such thing exists . emacs-nav http : code.google.com p emacs-nav offer a file browser similar to the one in ECB and you can use something like helm http : github.com emacs-helm helm to jump to various stuff in your project like files tags imenu entries etc . Small utils like projectile http : github.com bbatsov projectile might also be helpful to you . All in all using heavyweight tools like ECB is not the Emacs way and I guess this is the reason while its development has stagnated - few Emacs users would use a tool like that given there a smaller more flexible alternatives . Comment : Double vote for Helm now will checkout emacs-nav projectile", "Question : I m trying to figure out how to use Emacs Code Browser ECB and one of the things you can do with it is set ecb-windows-width to decide how wide the ecb windows are . The problem is this sequence : .. . .. . 1 . Frame pops up on screen . 2 . ecb-activate gets called scaled according to ecb-windows-width . 3 . default-frame-alist parameters kick in frame gets resized . The problem is that due to this order the width of the ecb window is set before the frame gets resized and then doesn t get scaled . So I d like to run ecb-redraw-layout or ideally just ecb-activate but it has to happen after 3 . Otherwise some sort of ecb-dynamic-width-scale option would also work . For what it s worth ecb-auto-activate doesn t work so I can t find out if that would solve it . Comment : Sounds like a bug you should email the maintainers of ecb . .. . Answer : I m unfamiliar with ECB but after-make-frame-functions might be helpful in running the functions you want or running some hook function where you want to do special things with the ecb frame . after-make-frame-functions is a list of functions that take one argument the newly created frame and is run after the frame is created . This doesn t apply to the initial emacs frame on startup because your .emacs is read after the frame is already created . Comment : Yeah I tried that hook but it doesn t seem to actually call the function nothing happens . In fact if I just do this : add-hook after-make-frame-functions lambda setq xx 1 and then try to evaluate xx after emacs has started it turns out the variable hasn t been set . Comment : The hook-function must take a single frame parameter . So after I do the following and call make-frame the variable xx does get set to 1 . I haven t tried it for the main emacs frame that is after launching emacs : add-hook after-make-frame-functions lambda the-frame setq xx 1", "Question : On updating to Kubuntu 12.04 and Emacs 24.1.50 - I can t access folder in ecb s tree browser .

Answer : I am using Kubuntu 12.04 and ran into this same problem don t know if it is specific to Kubuntu or 12.04 generally . Somehow the C : nppdf32Log debuglog.txt file http : askubuntu.com questions 144408 what-is-the-file-c-nppdf32log-debuglog-txt was being picked up by the internal ecb-filename-cache - I couldn t figure out exactly how ecb-filename-cache was being populated but I was able to see this by running ecb-remote-patch-cache-dump - this was the source of the tramp error for me . To get around it I removed all semantic cache directories all traces of the debuglog.txt file and any tramp files that I could find . Viola ECB works again .", "Question : I recently installed emacs code browser and noticed that CVS is integrated into it . Can ecb configured to use git as well Thanks . .. . Answer : I don t remember about CVS-specific support in ECB so I ll try to answer about generic Git support . Emacs VCS should support Git out of box - you can read about VC in official documentation or in my article about VC http : alexott.net en writings emacs-vcs EmacsVC.html . There is also DVC package http : download.gna.org dvc that is designed to work with different distributed version-control systems and have slightly more features than VC you can find more details in its manual or in this article http : alexott.net en writings emacs-vcs EmacsDVC.html . Although the best package for Git is magit http : philjackson.github.com magit - it support most of Git s commands and have extended features comparing to VC and DVC packages . There are also other Git-related packages I described them and also magit in other my article http : alexott.net en writings emacs-vcs EmacsGit.html . P.S . all these articles are parts of big article about version-control in Emacs http : alexott.net en writings emacs-vcs that describes many other version-control systems . Comment : There are version-control icons in ECB when you re using CVS so I guess that s what @morej is asking about . Comment : I ll try to check although ECB isn t working with fresh CEDET on my current machine Comment : ECB is poorly maintained for some time now . That ultimately made me stop using it . Comment : @Bozhidar : I was referring to the icons as well as the fact in ECB when I right-click a directory within the version-control menu I only see CVS options i.e . cvs status cvs examine cvs update . Since you no longer use ECB what do you use instead Comment : It s better to use Version control submenu from Tools menu - it provides access to VC commands that will work with any supported VCS", "Question : On updating to Kubuntu 12.04 and Emacs 24.1.50 - I can t access folder in ecb s tree browser .

Answer : When not specified C++ is unmanaged C++ compiled to machine code . In unmanaged C++ you must manage memory allocation manually . Managed C++ is a language invented by Microsoft that compiles to bytecode run by the .NET Framework . It uses mostly the same syntax as C++ hence the name but is compiled in the same way as C or VB.NET basically only the syntax changes e.g . using - to point to a member of an object instead of . in C using : : for namespaces etc . Managed C++ was made to ease transition from classic C++ to the .NET Framework . It is not intended to be used to start new projects C is preferred . Comment : A caution on the advice to not use managed-c++ for new projects . From Visual Studio 2008 onwards Managed c++ has some features that are superior to c . These relate to the handling of IDisposable objects .

Answer : You can code native C++ two different ways . The first is compiling directly to machine code with just the operating-system between you and the Platform Hardware . The second native coding is done with MFC Microsoft Foundation Classes . This is the same as the first example except for the use of MFC . Managed C++ uses the CLR Common Language Runtime The CLR along with the .net framework class libraries make up the .NET Framework . This managed C++ CLI standard uses the .Net framework along with the MSIL Microsoft Intermediate Language . This standard works by mapping to machine code only when the program is executing by the use of a just in time compiler . If your code will be running on different hardware platforms the use of managed code will be much easier . As with all thing there is a slight price to pay for convenience as native-code will run faster .", "Question : What is exactly the difference between the old Managed C++ and the new C++ CLI .. . Answer : Managed C++ is the version in VS2002 and VS2003 . It had race conditions and other serious bugs as well as being confusing . It s no longer supported . In VS2005 Microsoft introduced C++ CLI which has also been accepted as an ISO standard . It s also supported in VS2008 and the upcoming VS2010 . Both of them had the same goal which is to create .NET assemblies using the C++ language . The syntax is different C++ CLI managed code is a lot easier to differentiate from standard C++ at a glance and C++ CLI also has syntax for .NET 2.0 features such as generics .

A managed type can not be guarenteed to stay the same place on the heap as it originally was which is why you can t do that : Comment : Just a little nitpick : While Managed C++ C++ CLI will to my knowledge be compiled into the same code they re actually two distinct languages .

Answer : Managed C++ has been replaced by C++ CLI and managed C is just C . I would strongly recommend you to use C for a new project and use C++ CLI only when needed . C has a better support has a larger user base and is easier to work with inside Visual Studio 2010 . Additionally keep in mind that C++ and C++ CLI are two different languages .

C just fits that concept better .", "Question : We re looking at writing a .Net-callable wrapper for some legacy C++ libraries using managed C++ . It all looks pretty easy . Is there anything we need to watch out for .. . Answer : It is pretty straight-forward and works well . It is a lot easier than PInvoke . The big thing you need to watch out for is not having any unmanaged members in your managed headers including private members method signatures etc . It is okay to have private members that are pointers to managed types though just use forward declarations for your classes . Also watch out for object-lifetime . It is easy to introduce memory-leaks since many .NET programmers are not used to cleaning up after themselves . Make sure any wrapper classes that you create are disposable if they contain pointers and make sure you dispose of them in your managed code . The syntax for IDisposable in managed C++ is also weird but it is in the docs . Also remember that you incur a slight hit every time you cross the managed unmanaged boundary so try to plan your interface accordingly . If anything gets called repeatedly in loops it is probably better to move that loop across the boundary so you only cross once . Don t worry too much about this though unless you are talking millions of calls . This article goes the other way but it has some useful points .

A C assembly .. . .. . The Managed C++ assembly defines an interface let s call it ISetupHelper . There is a class in the C assembly that implements this interface The C assembly has a reference to the managed C++ assembly . Let s call this class SetupHelper . Since the Wise setup can t call directory to the C assembly we have this managed C++ assembly in between . There is a method that the setup calls to create an interface of a class that implements ISetupHelper . I does this by passing 2 strings to the C++ method the assembly path to the C assembly and the type name . The C++ method looks like this : .. . .. . This has worked very well for us for a number of years . Now we are trying to add support for Windows Server 2012 R2 . These versions of Windows come with 4.5 and 4.5.1 installed respectively . Here is where the odd problem happens . If the setup is run from a path with a long name it does not work if you run it from the short version of the path . When I say it doesn t work I mean the cast fails . For example : .. . .. . Running from this directory works : c : reallylongname .. . This does not work : c : really 1 .. . .. . I turned on the Fusion logger and when the cast fails it tries to load the C++ assembly again : .. . .. . LOG : IJW explicit bind . File path : C : reallylongname ManagedCPP.dll . LOG : IJW assembly bind returned a different path : C : REALLY 1 ManagedCPP.dll . Use the file provided . If you do this exact same thing on a Windows Server 2008 R2 machine with only .NET 4.0 installed running from the short path works just fine the cast is successful . It seems as-if something in the CLR has changed in the way it loads assemblies and in particular when loading an assembly with the same name as one that has already been loaded . Comment : This is really obscure . I d assume it has more to do with the operating-system . It is getting pretty common to turn short name mapping off . And that this runs as a setup program probably isn t a minor detail Windows has pretty heavy appcompat to keep ancient installers still working . A call to Microsoft Support is probably your best bet . Comment : I don t think it is OS related . I did not mention this but we tried this on a Server 2008 R2 machine with .NET 4.5 installed and it behaved the same way as the Server 2012 machine . So it certainly seems to be related to .NET 4.5 .

Note that Mono is a full .Net 4.0 compliant CLR and it can work with the Microsoft core libraries on Windows . On windows and Unix it can work with the Mono corlib class libraries . There are areas not covered in Mono but they seem to get sparse . You can use the MoMa tool to spot whether your application uses incompatible incomplete APIs . Or you can just use the Microsoft .NET framework assuming you re on windows anyway", "Question : For deployment reasons I am trying to use IJW to wrap a C assembly in C++ instead of using a COM Callable Wrapper . I ve done it on other projects but on this one I am getting an EEFileLoadException . Any help would be appreciated Managed C++ wrapper code this is in a DLL : .. . .. . Test Code this is an EXE : .. . .. . For what it s worth the Event Log reports the following : .NET Runtime version 2.0.50727.143 - Fatal Execution Engine Error 79F97075 80131506 .. . .. . Unfortunately Microsoft has no information on that error . Comment : Do you have tests in-place to verify that the assembly loads from the same directory Comment : When I manually copy the managed DLL into to exe s directory it worked without this extra code . .. . Answer : The first issue is to make sure the Debugger type is set to mixed . Then you get useful exceptions . Comment : I ve got his problem with an Excel addin written in Managed C++ and I actually found with mixed debugging that I get less useful exceptions in particular I don t see the EEFileLoadException itself just several subsequent rethrows . Comment : This advice probably saved me an hour of debugging ." ] }

Answer : No you can t touch the browser default stylesheet and yes browsers do have different rules for box-sizing specifically in respect to form fields . This is for compatibility with old browsers that used to implement form fields entirely with native OS widgets that CSS couldn t style and so which didn t have border or padding as such . Why not just put your box-sizing -moz-box-sizing -webkit-box-sizing rule in the site stylesheet Works for me I often use this to make inputs with set widths line up across modern browsers . IE 6 7 don t support it though so need some extra help . Comment : I ended up explicitly defining box-sizing -moz-box-sizing and -webkit-box-sizing in the style sheet but I was hoping to find out what might have caused this weirdness with the user-agent stylesheet . Comment : Well user-agent stylesheets are never guaranteed to be the same but form field rendering is particularly diverse due to the number of different approaches browsers OSes have had towards styling forms with CSS vs native OS theming . Comment : Hi bobince -- I know all too well that different browsers and OSes handle these things differently . We all should as web developers LOL . My issue isn t really with that but with the strange behavior I m experiencing where on isolated small little test pages I m getting the right default behavior whereas on this particular page in my application I m getting this wrong default behavior . In other words the wonky defaults that change from browser to browser should at least be consistent within the single browser but I m not seeing that here .

Answer : If you want to support old browsers like IE8 you can use this method by doing little math .

According to everything I ve ever read understood and used https : developer.mozilla.org en-US docs Web CSS box-sizing about box-sizing : border-box This should show nothing since the width and height are zero and padding border are inside of the zero width and height . What we see however is a 26x26 box 12 padding + 1 border 2 . What gives Why is border-box not working here Comment : What you want is physically impossible . The browser has to make a choice : either honour the padding or the width . If it would show 0 pixels people would start complaining that it didn t honour the padding . Comment : @MrLister That s the definition of box-sizing : border-box isn t it That width includes padding and border Comment : @MrLister : I don t think this represents an impossible goal so much as it represents a potential bug ambiguity in the spec versus expectation . Comment : @MrLister Correct however I would assume that the browsers internal rendering logic has some conditional that will render this a certain way based on whether or not is has content . Hope you get a detailed answer . Comment : Yeah seriously @DavidThomas that could certainly be considered a bug in the spec .. . Answer : According to the spec http : www.w3.org TR 2015 WD-css3-ui-20150224 box-sizing .. . .. . The content width and height are calculated by subtracting the border and padding widths of the respective sides from the specified width http : dev.w3.org csswg css2 visudet.html propdef-width and height http : dev.w3.org csswg css2 visudet.html propdef-height properties . As the content width and height cannot be negative http : www.w3.org TR CSS21 visudet.html the-width-property CSS21 section 10.2 this computation is floored at 0 . Therefore your element effectively has a height and a width of 0 . But you see it bigger because of the padding and the border . Comment : That doesn t really explain what s going on here . Should the height and width be zero then Comment : @GeorgeMauer Again what you are trying to do is physically impossible . Comment : @GeorgeMauer I think the important part here is where it says The content width . So the content width is 0 but the padding and border are still applied on top of that . Comment : Oooooh I see what you re getting at . Well hell...how do you do a zero-sized container with a padding that expands to a width then Do we still have to hack around things with intermediate elements Comment : @GeorgeMauer An outer wrapper that s 0 and an inner element with the padding", "Question : This question already has an answer here : .. . .. .

Answer : The problem is that inline-block elements are by default rendered with a bit of extra space . Why Because a div set to inline-block has some inline element characteristics . A space or line break between span elements will result in a space rendered by the browser . Similarly if you re writing text in a p element every time you hit the space bar or add a line break a space will be rendered by the browser . This same rule applies to inline-block divs . A space or line break in the source will result in a space rendered . This creates unexpected width which can result in an overflow or wrapping . One solution is to remove all whitespace between elements in the source : .. . .. . .. . .ok .. . width : 300px .. . background : red .. . height : 100px .. . box-sizing : border-box .. . .. . .box .. . display : inline-block .. . box-sizing : border-box .. . width : 25 .. . border : 2px solid blue .. . height : 100 .. . .. . .. . .. . div class ok div class box 1 div div class box 2 div div class box 3 div div class box 4 div div .. . .. .

All it does is make it so that when you specify a size for an element that size includes everything except the element s margins .

I understand what border-box can do that s why I thought it ideal for this web page design . It s working correctly on the left and right borders as can be seen by the 4px gap between the columns . What I can t figure out is why on the top and bottom borders of the image black-box of cards aren t contained within the image-size also . They are outside of it as can be seen by it pushing the image below it further down . It s bottom edge is no longer level with the image at the bottom of the right-hand column .

By default it is set to box-sizing : border-box but just change that in the styles to get different results . It calculates offsetWidth and clientWidth for you when you click the button .

Answer : The size of a flex item with padding and flex-grow is based on calculations outlined in the flexbox specification https : www.w3.org TR css-flexbox-1 . These calculations are similar to the sizing of flex items with padding and flex-shrink . Frankly the math is quite technical and not the easiest thing in the world to understand .

How does flex-shrink factor in padding and border-box http : stackoverflow.com q 34753491 3597276 .. . .. . .. . .. . Below are some examples that hopefully make the behavior more clear . Keep in mind flex-grow is not a tool for directly establishing the length of a flex item . It s a tool for distributing space in the container among flex items . The flex-basis property sets the initial main size of a flex item . If flex-grow is used with flex-basis the problem in the question is resolved see Demo 4 below . .. . .. .

Somehow it came to my mind : what if I just apply box-sizing to all elements in the website I m one of those who believe that box-sizing : border-box is one of the best commands there is in CSS with all its limitations . However those same limitations are the ones who make me wonder if I should apply box-sizing to all elements : .. . .. . Of course my website should be compatible with as much browsers as possible and box-sizing creates a few questions when we think about IE7- .

We ve been using box-sizing : border-box in one of my projects deployed in production averaging over 1mln visits a month at work for about a year now and it seems to be holding up just fine . The project has been tested in IE8 9 and the latests Firefox and Chrome versions and we ve had no problems . All jQuery +UI offset calculations and animations run fine even in any element we ve displayed as inline-block . As of late we ve started testing the project on mobile-devices iPhone iPad and Android and we ve had no issues regarding box-sizing with any of them yet so it seems to work just fine .

UPDATE : While BoltClock gave a really great explanation and suggestion which was all I was asking for I just wanted to mention that I totally forgot about flexbox https : css-tricks.com snippets css a-guide-to-flexbox which solved pretty much all the problems I was having with inline elements . I combined it with BoltClock s transparent border trick for my final JSFiddle solution https : jsfiddle.net gxzy6t0f 1 Comment : You have a typo . Your CSS says box-sizing : border-box - you have a space rather than a dash in border-box . Comment : alright I fixed the typo thanks . The problem still persists though : .. . Answer : I see the problem now . What s happening is that box-sizing : border-box causes the content box of each element to shrink both horizontally and vertically once you add a border . Because your elements are inline-blocks the vertical shrinking affects the baseline of the element being hovered and therefore the baseline of the line it s on resulting in the other elements on the same line being offset . If you look closely you ll notice that the text actually stays aligned which is the goal of offsetting the elements . Changing the border to an outline works because outlines are designed to have no effect on layout and also because you then take borders completely out of the picture . However it is for this reason that using an outline this way produces a significantly different effect from your original effect with a border . Setting an initial transparent border instead of an outline will ensure that your content stays offset the right amount whether the border is visible against the background this was shown in a previous answer but it was deleted presumably because it was downvoted : .. . .. . .. . box-sizing : border-box .. . .. . ul font-size : 0 .. . .. . li .. . display : inline-block .. . width : 100px height : 40px margin : 10px .. . font-size : 20px text-align : center .. . background-color : FFF176 .. . border : 5px dashed transparent .. . .. . .. . li : hover border-color : grey .. . .. . .. . ul .. . li hover li .. . li over li .. . li me li .. . ul Comment : that transparent border is a sweet trick thanks for the tip", "Question : Dear stackoverflow users .. . .. .

Comment : @AoN : I tried this now . Same problem unfortunately Comment : As I toyed with the signature a little I noticed that Outlook.com was replacing the spaces with nbsp which then caused extra spacing . Try removing all spaces between your tags minify the code so it would be something like table tr td td td td tr table no spaces and no line-breaks . Comment : @AoN : Thanks for all the help . Unfortunately this didn t work either I used this tool https : kangax.github.io html-minifier to minify . Comment : I m sorry I m just not able to duplicate the issue after minifying your original code or substituting the height for styling and I ve loaded it in IE10 IE11 FF36 and Chrome 41 . You may have to bring it up to Microsoft or replace the table with a div structure . .. . Answer : What you re seeing is Outlook.com s line-height increasing feature . What you need to do is put div class ExternalClass after the opening and before the closing body . in your style tag add .ecxExternalClass line-height : 100 important .. . .. .

I already created add-in for Outlook Web Application and tried to deploy it to desktop client but didn t figure how to make it . So how to make it set on desktop and outlook.com Is that really possible And if yes how it can be done .. . Answer : Technically you can t make an add-in that will work 100 on all clients . The web-based add-ins currently only work with Mailboxes hosted on Office 365 or Exchange 2013 or greater and with Outlook 2013 or greater . Outlook.com integration is coming this spring . COM desktop add-ins work with Outlook 2000-2016 but not in OWA . To deploy an add-in you need to either publish it to the Office Store or an Exchange Server . See here for more info : https : msdn.microsoft.com en-us library office fp123515.aspx . To install a self-published add-in that is not in the Office Store you just add the manifest file from the Manage add-ins page in OWA : https : msdn.microsoft.com en-us library office fp142256.aspx .. . .. . Note also that you must host your web add-in code in your own web server and secured with an SSL certificate . Comment : Okay it s done - my add-in works fine with OWA .

Anyone know of another technique to hide content for Outlook without breaking Outlook.com emails After more testing I found that this works in Outlook app and Outlook.com : .. . .. . I don t know if it was the gte part but looks to work better with that removed . Thanks for the responses . Comment : May we know what you are trying to hide and why Comment : I was using it to hide the pre header at the beginning of the body content . But same would be true for hiding content for mobile-only . .. . Answer : outlook.com eats anything in a comment conditional or not . Your best bet is to copy the section that hides in outlook 07 and paste it below the conditional comment end . Then give that pasted section s main container table a class outlookcomonly and a style display : none . In your style tag : .. . .. . Outlook.com preprocesses your classed items adding ecx before each of them . If you add that ecx to your style sheet outlook.com will see it but all other clients will ignore it .", "Question : Use-case : Emails to be sent from a web-application upon an event as someuser@somedomain.com via MS Exchange or Outlook.com using the RESTful APIs exposed by Outlook.com https : msdn.microsoft.com office office365 api mail-rest-operations SendMessages . Only HTTP access allowed no SMTP IMAP . All documentation https : dev.outlook.com restapi seems to mention that the app has to forward users to MSOnline https : login.microsoftonline.com common oauth2 v2.0 authorize sign-in and then use the authorization code sent back by MS online . But this won t work for a background task no sign-in possible where a pre-built token with some predefined scope is necessary so that Outlook.com can be accessed via APIs to send mail as someuser@somedomain.com . Any hints pointers to how it could be done Basically automated authentication without explicitly signing in as someuser@somedomain.com on the MS Online login page . I did not find M documentation regarding Outlook REST APIs https : dev.outlook.com restapi to be of any great help and found it to be pretty difficult to navigate understand . : .. . .. . Thanks Comment : I don t know this API in particular but generally you have to register and get an API key to be used from your code . This link https : msdn.microsoft.com en-us office office365 api mail-rest-operations UsetheMailRESTAPI mentions token you can obtain after registering your app maybe you should try that . Comment : @cdelmas thanks I did try that . Apparently the only possible way is to register the app at Azure AD and if need be limit the users that can access the app again at the Azure AD level and then let user s sign-in to the app and thus generate a token which again comes with a rigid 90 day expiry limit . .. . Answer : At some point you will have to have the user sign in to grant access to your app . So you would need to have some sort of user-facing web front end where they can do this . Once they have signed in and you ve obtained an access token refresh token your background app should be able to use those tokens silently without user interaction at least until the user either revokes access or the refresh token expires . Currently Azure which provides the login token functionality does expire the refresh tokens after some time 90 days at which point the user must sign in again to grant your app continued access . Comment : Thanks for the info Jason So one truly cannot use outlook.com APIs in an enterprise solution since one really cannot force the admin maintainer to sign-in to the service account every 90 days and regenerate the refresh tokens . Any plans to accommodate refresh tokens that last for a long time as governed by the user The use-case doesn t involve a normal user but a service account which traditionally will not have password expiry etc set . Comment : My understanding is that yes those plans are there . However I m concerned I ve misunderstood you . Outlook.com accounts aren t typically involved with an enterprise solution . Are you accessing Office 365 Business work accounts or Outlook.com personal consumer accounts Comment : However I m concerned I ve misunderstood you . Outlook.com accounts aren t typically involved with an enterprise solution . Are you accessing Office 365 Business work accounts or Outlook.com personal consumer accounts The use-case is to build a mailing component for a client of ours with below listed constraints . 1 . The client say somecompany.com wants the emails to be routed via their corporate MS exchange only 2 . The sender stamp on the outgoing emails should be someuser@somecompany.com 3 . No SMTP IMAP access to the exchange allowed . contd. . Comment : This mailing component will be used in background by an enterprise system that would send out emails to external @ somecompany . or internal @somecompany.com addresses . So we will have to 1 . create one service account someuser@somecompany.com 2 . create an app on somecompany s Azure AD 3 . Restrict access to someuser@somecompany.com for the app 4 . Make him sign-in and obtain the refresh token 5 . Use that refresh token to generate access tokens so that mails can be sent by the mailing component . contd . . Comment : Now this flow would require 1 . someuser@somecompany.com to sign-in to MS online page every 90 days to regenerate the refresh token and 2 . make this new token to be accessible to the mailing component so that it can use the token and send out mails in background . This would not be acceptable for an enterprise solution I mean the obligation to sign-in every 90 days . : I hope I have made my use-case clear . Please let me know your thoughts .

Answer : Unfortunately there is no way to prevent Outlook adding the p tags we just have to find ways to zero them out . Try adding margin : 0 padding : 0 inline to all your image tags and add outlook a padding : 0 to your header style tag . Also removing the space between your anchor and image tags may possibly stop the spans from appearing . Not 100 sure but worth a try . If none of that works try targeting .ecxMsoNormal in your style tag as you would for the web . Any styles you apply there should take affect as Outlook reads it unlike Gmail .

Hope it helps .. . Answer : Jaxer and node.js are very different things . Think of Jaxer as Firefox running on the server-side but instead of a GUI its interface to the outside world is Apache . It can do pretty much anything a browser on the client-side can do : fetch pages from a third-party server run JS against that page pull elements from it via the DOM substitute new content into it etc . Jaxer can also work more or less like ASP or PHP simply executing JS inside special tags inside the HTML files Jaxer serves up via Apache so that you can insert some dynamic-content into those otherwise-static pages . Jaxer has one huge disadvantage : it is dead technology http : stackoverflow.com questions 2095793 web-host-with-jaxer 2103165 2103165 . node.js on the other hand is not a browser running on the server it is very much alive right now and it doesn t have any tie to Apache or any other standard web server . You can build your own web server using node.js s HTTP component http : nodejs.org docs v0.5.4 api http.html but that brings on The Lisp Curse http : www.winestockwebdesign.com Essays Lisp Curse.html : because there is no standard web server everyone builds theirs a different way so that there is no concentrated expertise on the subject . The same goes for templating and other things that go into an ASP or PHP type platform : no complete built-in component means you end up assembling your own from the provided pieces . This makes node.js best suited for projects where you were already going to have to reimplement everything yourself so what you want is a box of tools and components rather than a platform . If you can fairly describe your project as a web app meaning that it s an application that just happens to show its UI via the web and most of its content is dynamically-generated rather than being served from files node.js might be a fine choice . If instead you just need to substitute some dynamic-content into a mostly static presentation well I cannot really recommend Jaxer but something like it that plugs into a standard web server is a better choice .

Answer : Personally I liked Jaxer because you easily could use the same code client and server-side without duplication such as form validation however I didn t like that you had hardly any control over the generated pages which where propped full of JavaScript even for the most trivial page and made the pages highly depended on JavaScript which made unobtrusive JavaScript virtually impossible .

Answer : I remember taking a look at Jaxer back when it came out . I don t remember any sample applications at the time though . I wanted to get a feel for what it was good at . Just because a language is cleaner may not be enough to get people switch . What is its unique benefit For example Node.js is good at real-time applications and they make that relatively clear in the sample code on their front page . I think there was also been more uptake of Javascript since Jaxer was initially released . There seem to be more back-end developers who now also know Javascript . I would say that s more true now than when Jaxer was released . In other words maybe it was ahead of its time . Comment : Hi Matt Well I don t know if Jaxer has any unique benefit . I understand what you mean talking about Node.Js . Now I haven t really looked into it that much but from what I see Node.JS isn t really meant as a replacement for PHP . I was more thinking of using Jaxer for what PHP is used mostly i.e . your normal server-side website programming sort of thing where most of the time you don t really have much use for the asynchronity .

Is it really a better approach than using server-side languages assume c how we can compare this with the c implementation of a website performance language features And which one is a better approach using JS alone in serverside or JS in middle layer between other language stack and webserver .. . Answer : As a preface I use SSJS at my day job . We run a reasonably large in terms of complexity as well as page views website on SpiderMonkey . I ll add to Matthew s excellent answer where I have experience . Is it really a better approach than using server-side languages assume c .. . .. . Better really depends what you want to do with it . JavaScript itself has some great features as well as pretty awful ones . If you re serious about developing JS client or server I cannot recommend highly enough that you watch Douglas Crockford s presentation Javascript : The Good Parts http : www.youtube.com watch v hQVTIJBZook if you haven t already . He s done a fantastic job sorting out the cruft and he s an excellent speaker to boot . The biggest thing that I find the SSJS world lacking right now is maturity . I m not familiar with C but JavaScript has no mature standard-library and no mature means of package distribution . To me that s a big piece of the puzzle . That said keep your eye on the CommonJS http : wiki.commonjs.org wiki CommonJS group . They re working toward defining those exact things . Also The Jaxer Api Documentation lists the built-ins that are included with that framework . how this works well in terms of performance .. . .. . JavaScript itself is not a slow language nor is it a particularly fast one . As Matthew pointed out it should be comparable to any other scripting-language you would use . The war between the browser vendors to see who can build the fastest browser will benefit the SSJS crowd as well . The generational garbage-collection that the V8 team-build into their engine is a great example of this . Halting the virtual-machine to free unreachable objects from the heap and reclaim their memory can be somewhat slow but they ve mitigated that by reducing the amount of objects that need to be inspected when the garbage collector runs . how well we can implement maintain db transactions can we do that in serverside JS. . .. . .. . Jaxer appears to have MySQL and SQLite database APIs . As Matthew mentioned if you use Rhino you can use the JDBC api .

Answer : I didn t use Jaxer for very long but here s some things I found : .. . .. . Pros .. . .. . Write the frontend and backend in the same code . Especially nice for writing validation logic . Seamless AJAX communication back to the server - it s just like calling a JS function . The ability to use JavaScript frameworks like jQuery to manipulate the DOM . The ability to generate or manipulate images using the Canvas API . You get to write your server JavaScript using whizzy new JavaScript 1.8 features like Array extras and getters setters . Cons .. . .. . I found their API to be unstable they were transitioning to 1.0 when I was trying it so that kinda made sense and the documentation was confusing missing or didn t match with changed functionality . I also found that it was very hard to debug my Jaxer server-side code and when I got in trouble the error messages weren t very helpful . You don t get real MVC or even MVP ASP.NET-style separation between your presentation and your logic . I personally couldn t get E4X xml in JavaScript working which was supposed to be a big draw . There s not a lot of framework built around it for building a whole application . You re starting from some pretty basic building blocks . It s not really providing any help in your view so forget all the templating or reusable components you might use elsewhere . Not that you can t replicate that but it s more difficult than having it out of the box . Overall I think Jaxer has the most promise as a postprocessor in front of another web framewok . It would be great to use Jaxer to layer all the spiffy AJAX stuff on top of an existing site . It would make it a lot easier to make a dynamic site with validation page manipulation logic shared between server and client . I don t think I would want to write an application using only Jaxer . Also it s young and immature - I ll be interested to see where it ends up . Comment : I have installed Jaxer now and the first thing I tested was the E4X functionality . Seems to work great and is a very powerful tool . You do have to keep in mind that E4X code should be kept server-side as Mozilla is the only browser that knows what to do with it . Comment : Yeah I know that it s a Moz-only . As I said I was using it right around the transition to 1.0 during the betas and I had a hard time with E4X . If it works it s wonderful if it doesn t it s totally opaque .", "Question : I m a guy who s hosted on HostGator because I want cheap PHP hosting . However I ve been playing with a Jaxer server on my linux box and I d like to write web apps in it . Can anyone recommend an affordable host that runs or will allow me to run Jaxer I d rather not get a dedicated or VP server.. . Thanks to the community .. . Answer : Jaxer is dead technology . Some hacker-necromancer may resurrect it but it doesn t look likely . Jaxer 1.0 was released in January 2008 and only received a few minor upgrades after that mostly fixing typical 1.0 bugs and limitations . The last release 1.0.3 is about three years old as I write this . Three years is a long time to wait for an update to an open-source product particularly given that Jaxer died pretty much right as the whole Javascript speed race began . Jaxer is based on Firefox 3.0 so it does not have the TraceMonkey https : wiki.mozilla.org JavaScript : TraceMonkey and J gerMonkey https : wiki.mozilla.org JaegerMonkey advances Mozilla has made since that release . Jaxer s code has since been placed into a public source repository https : github.com aptana Jaxer but no substantial commits have been made https : github.com aptana Jaxer commits master since that initial checkin . The old support forums are closed http : forums.aptana.com and the new Jaxer mailing list carries little content http : groups.google.com group jaxer pli 1 . It mostly consists of unanswered questions . Aptana the company that created Jaxer was bought http : www.appcelerator.com 2011 01 appcelerator-acquires-aptana by Appcelerator a desktop-focused company . Appcelerator s Aptana acquisition FAQ http : www.appcelerator.com aptana-faq says they intend to continue developing the server-side Python PHP and Rails products . Jaxer is left out of this being described as in maintenance mode with announcements to come in late Q1 of 2011 . Since then crickets . Before the Appcelerator buyout Apatana dropped Jaxer from the Studio download . You could then and still can download it http : jaxer.org separately but that s small comfort given that the support for it seems to be if it breaks you get to keep both pieces . Even if Jaxer were a healthy thriving project it still has some serious drawbacks : .. . .. . 1 . Browser Javascript the platform Jaxer is built on doesn t know how to run code in trustably separate sandboxes so you need a separate interpreter for each site hosted on the server . That costs memory one of the biggest drivers of higher hosting fees . 2 . That wouldn t be so bad if the core technology was a parsimonious user of RAM but it s not : it s Firefox a RAM-hungry program . While debugging a server crash due to it running out-of-memory I found that the core problem was that launching an external process ballooned the VM use by 35 MB . It was a one-time hit for the first launch only not a memory leak but multiply that by the number of Jaxer processes you have serving connections 3 by default with more better for performance and you re already over the 64 or 128 MB limit for some cheap hosting plans . Absolute bare minimum to host a functional Jaxer site is 256 MB and 512 MB is a lot safer . 3 . You can get around some of the RAM hungry nature of Jaxer by running on a virtual-machine technology that lets you have swap space so things like the GUI libraries Jaxer uses don t stay in RAM but many do not . Often you have to use more expensive hosting to get something like Xen rather than a more efficient VM system like OpenVZ that doesn t let you use swap space . 4 . Because Jaxer isn t being patched any more there are still bugs in it that can crash or hang the server . I ran into one where some random bot out on the net was accessing random URLs on my server causing Jaxer to run for each one eventually running the system out of resources . I had to rearchitect the way my site was built so the bot s hits were served only by Apache restricting Jaxer to a single sub-tree of the site . That s just a workaround though because all you d have to do to start crashing it again is to access lots of random URLs in the new sub-tree . Every month or so I have to reboot the VPS because it s consumed all the RAM probably because someone s stumbled across this weakness in the design . Bottom line Jaxer is completely unsuited to cheap shared-hosting . Lest you think I m some Jaxer hater let me pre-defend myself by pointing out I was an early adopter of Jaxer pre-1.0 was one of the most active posters on the original forum and have two sites running on Jaxer . Yes I m upset but mainly because one of those sites was migrated off one dead technology onto another that died within a year of that move . The other was created from scratch after I successfully migrated the first . Now I m stuck wondering whether I now have to move again or keep trucking along on a platform that looks like it won t move forward ever again . You don t want to be in this same boat much as I might like the company . Comment : Wow.. . thanks for all the extensive info . I have to disagree though that not being able to run something on a cheap shard host is a big let down - i don tthink 20 mo is unreasonable . Back in 98 2k i paid nearly that much for shared-hosting alone with like a few hundred MB . Now you can pay that and get a dozen or so gigs + root on the box . Im automatically skeptical of anything thats less than about 10 mo anyhow . I realize if you jsut need to host a blog or something thats ridiculous but if youre deploying an app.. . even a simple one i think its a non issue myself . Just MHO though . Comment : The size numbers above are all for RAM or more accurately virtual-memory since that lets you expand RAM . Since you re talking about dozens of gigs I guess you mean disk space instead . My cheap unmanaged VPS plan with 512 MB of dedicated RAM costs me a fair bit more than 20 month . Looking around it seems I m paying about in the middle of typical fees for this . To my mind cheap shared-hosting means below 20 month .", "Question : I found a project jaxer http : jaxer.org which embeds Firefox s JavaScript engine on the server-side so it can parse HTML server-side very well .

Answer : ItsNat http : www.itsnat.org is similar to Jaxer the main difference is Java based instead of JavaScript .", "Question : Remember Aptana Jaxer It plugs into Apache and allows using JavaScript on the server-side as an alternative to languages such as PHP . It comes with a consistens and slick API for filesystem-access database connectivity socket communication and whatever else you need . I wonder why hasn t this been more widely adopted why aren t more people using this Javascript is a modern and clean programming language as opposed to PHP and the Jaxer API is just so much more consistent and neat . No offense but the PHP API is just such a big mess with all its inconsistencies and its inconsequent function naming convention . Jaxer also makes client-server communication really convenient with its runat server-proxy where you can directly call server-side function from within your client-side script and Jaxer takes care of all the XML HTTP request stuff . So I would just really like to here what people think about it or why there s hardly anyone using it . Not wanting to start a flamewar here I m just curious .

Answer : Well first of all there is Node.JS http : nodejs.org out there too . Far more people have heard of that probably . And people do use node especially when it comes to chats and similar things : Things there long-polling is appreciated . My personal problem with node is that it is so asynchronous . That s a very very very big pro on one hand because is allows most awesome performance and makes some things so much easier but on the other hand it is a big minus for those used to synchronous programming-languages . I simply have problems with looking at code which has 15 callbacks nested in each other.. . Comment : Yea I ve heard about Node.JS and I agree that it s asynchronous nature certainly can be awesome for some things but it s often overkill if your program is just not supposed to make use of that . So that s why I m asking about Jaxer because in my opinion that can be more directly compared to PHP . Comment : Yes my answer is only slightly related to your question .

I haven t even been able to find any tutorials or posts about this issue . Does anyone know if it s possible and if so what am I missing .. . Answer : Jaxer and Aptana Studio do not yet have the ability to debug remote scripts from the client-side . That is you can t single-step into a callback and have your code window show you the first line of code in the remote method . This is on their wishlist of course but it d be pretty tricky to do well . Personally I use logging . Jaxer has strong facilities for this in Jaxer.Log . . A lot of people sneer at printf debugging but the fact is it works and it s often less trouble to set up than an interactive debugger especially for server applications and remote method invocation . You just sprinkle logging messages wherever you want to know the state of the system at that point then make your app try to do the thing that s failing . Study the logs rinse repeat .", "Question : I have an old tool an ex- colleague wrote a few years back with Jaxer that I d like to replace rewrite . Jaxer https : github.com aptana Jaxer is an abandoned server-side framework based on a headless Mozilla Gecko-Browser allowing you to use JavaScript and the DOM server-side . Since Jaxer is abandoned and because I have big problems installing and running Aptana Studio 1.5 with Jaxer on a new computer I m looking for a library framework something on which I can base a new version . This tool is only run locally inside Aptana Studio the IDE for Jaxer and was never intended to be an actual web app . It crawls our customers websites by loading them page by page into the server-side Mozilla . In order to do that it uses jQuery and predefined CSS selectors to find the links in the menus and parse other information out of the pages . The final result is basically a glorified sitemap . I d like to keep this modus operandi if possible and continue using jQuery JavaScript the DOM to load and parse access the pages but it can be wrapped in a framework based on another language such as Java . I considered writing something based on Gecko myself but that seems a bit over the top so I m open for an other suggestions . .. . Answer : As far as HTML crawling parsing goes : http : ccil.org cowan XML tagsoup .. . .. . or .. . .. . http : jsoup.org Comment : TagSoup isn t really useful here because as a SAX parser I can t use XPath or CSS and I d have to individually write script routines that find the information I need or am I wrong . jsoup however looks promising since it supports CSS selectors .

Using CUrL I can easily grab the page it s content do POSTing etc etc but what I can t do is run javascript . I ve had solutions suggested from building a .NET application which calls the URLs in a browser to the above Rhino and Jaxer but I wanted to see if anyone had any previous experience of this and if so what are the possible gotchas and how did you solve the problem . Cheers .. . .. . Mike Comment : @Srinivas : No . JavaScript is a language not a client-side language . I use it on the server all the time . In fact it was one of the first server-side scripting languages the old Netscape Application Server supported it circa 1997 . Every version of IIS has supported it for server-side scripting in ASP and ASP.Net pages . Etc . Comment : @T.j.Crowder Thanks i didn t know that Comment : One of the potential problems you face @Mike is that the Javascript on those pages is likely to expect that it will have access to the page DOM and that the DOM will look the way the code expects it to look . That means that your server-side code will have to parse the surrounding HTML and provide at least some portion of the DOM API for the Javascript to use . You can cross your fingers and hope that the HTML can be parsed with some server-side XML parser but that might be a challenge . Comment : @Mike : I have not done this but in order for the JavaScript in the remote page to run properly it s going to need to think it s running client-side in fact you re basically going to be using your server as the client of that other site if you follow me . That means it ll need to have a DOM to manipulate and such . That suggests you re going to have to run not just Rhino but nearly a full-on browser . It s probably worth looking at the WebKit or Gecko engines for DOM and SpiderMonkey Firefox s JS engine or V8 Chrome s for JavaScript . This is a non-trivial task . Comment : @pawel well ok then that sounds awesome and quite appropriate to the purpose .. . Answer : I think Jaxer is your only option . You can use Jaxer.Sandbox http : jaxer.org api Jaxer.Sandbox.html to render remote page on the server and execute all scripts embedded on that page .

Is it really a better approach than using server-side languages assume c how we can compare this with the c implementation of a website performance language features And which one is a better approach using JS alone in serverside or JS in middle layer between other language stack and webserver .. . Answer : By using server-side JS can we implement the whole web application without using any server-side languages like C java etc . .. . .. . It shouldn t be necessary to write code in any other languages although many server-side JavaScript frameworks use the Rhino engine which allows you to call any Java code . Is it really a better approach .. . .. . I don t think JavaScript as a language is really a better or worse option than traditional server-side languages . It has advantages along with other dynamic languages like Ruby and Python like flexibility fast prototyping no pun intended flexibility etc . On the other hand it doesn t have the library support that Java and C have or static-typing I won t get into the debate over which is better here I like both for different reasons . If you want the best of both you can use JavaScript as a scripting-language embedded in your application . Rhino for Java and JScript.NET make it easy to manipulate native objects in JavaScript . You could for example write your domain classes in Java or C and script them with JavaScript where you want more flexibility . If you are comfortable enough with JavaScript writing in a single language may be simpler though . I ve never written a real server-side application using JavaScript so I can t really make a judgment about whether its better or worse than .NET I ve also never used JScript.NET . I have played around with a few frameworks for fun though and I m currently rewriting my personal site using Helma NG . So far it s been a good experience much better than PHP which I ve never really liked . what are the advandages and disadvandages .. . .. . Advantanges : .. . .. . Only one language needed for server-side and client-side programming . Possibility for shared code for things like form validation . Jaxer lets you run scripts on the client-server or both . You get to program in JavaScript assuming you like the language . Disadvantages : .. . .. . Many frameworks are experimental not very mature .

Answer : tail -f opt AptanaJaxer logs jaxer.log", "Question : I found a project jaxer http : jaxer.org which embeds Firefox s JavaScript engine on the server-side so it can parse HTML server-side very well . But this project seems dead . It is really helpful for crawling web pages to parse HTML extract data . Is there some new technology useful for extracting information .. . Answer : Another interesting way to do this is to use node.js http : nodejs.org in conjunction with jsdom http : github.com tmpvar jsdom and node-htmlparser http : github.com tautologistics node-htmlparser to load a page and parse the javascript in it . It is not really working out of the box yet at the moment but Dav Glass from Yahoo have had success running YUI in node.js http : www.yuiblog.com blog 2010 04 09 node-js-yui-3-dom-manipulation-oh-my using a modified version of this combo . This is interesting if you decide that nothing out there is good enough and you want to implement your own . If so it would make an excellent open-source project . Comment : note : I m adding this as a separate answer because it is a radically different solution to my previous answer ." ] }

It is easy to use . Then there is a suggestion of Coded U I . Can someone tell me the pros and cons of Ranorex and with coded UI .. . Answer : Easy : Ranorex can be used by non-programmers or by people with little programming knowledge .. . .. . Programmers are usually very though to hire for tests . As for Coded UI I assume in Visual Studio it is more tedious and requires programming skills . I have personally done this comparison and came to the conclusion that a tool must be used for automation even if I am a programmer . Then we chose Ranorex but there are other tools which are doing very good job . We chose Ranorex because it supports all the technologies we use Web Android iOS and WinForms and it support standard .NET programming which is a language that we use internally . In the end it all depends on your test automation budget", "Question : Reading through the Ranorex documentation I m unsure how you can run these tests unattended . When running from a CI process do you need a separate machine that operates the UI .. . Answer : When running unattended coded UI tests a dedicated computer VM is required and must be configured to run UI tests no screen lock . It can be either started manually at the end of the day using Ranorex test suite runner which is acceptable as a first step towards test automation or automatically using a test controller . Usually the test controler is integrated to the build-server and executes tests automatically on newly available builds .

We create a test method consisting of simply a call to Ranorex run configuration .

What is the reason that is creating this issue Also can anybody suggest good video tutorials for beginners for Data driven testing with global parameters .. . Answer : The good way to automate is to write code without using recorder . There are some reasons of it : .. . .. . 1 . recording unnecessary steps .. . 2 . saving elements to repository by wrong attribute . As usual there are automation id and regex of text or caption of element . For dynamically changeable elements this doesn t fit . 3 . different types of elements requires different types of methods to wait and validate them .

According to you exceptions and errors in comments : .. . .. . 1 . ...ATagPrintReport3 does not match the specified value actual False expected True It means that Ranorex recorded element ATagPrintReport3 with value of some bool attribute .

Failed to find item updtaed cpt imsRepository.OpeningInventoryStockValueJpg.ButtonOK . No element found for path form @title Opening Inventory Stock V button @accessiblename OK within 1m . This error can be the result-of very fast dynamically changeable element the wrong path of element it could be presented in dom but could not be visible . The best way to know what s wrong is to use breakpoints and step-to-step debuging . In my opinion the path for ButtonOK will be better if it looks like : form @title Opening Inventory Stock button @name OK .. . .. . 3 . No element found for path form @title Reading Untagged Document button @text Cancel within 1m . It is the same to p.2 .. .

What is the reason that is creating this issue Also can anybody suggest good video tutorials for beginners for Data driven testing with global parameters .. .

Evaluating ranorex for the upcoming projects in our organization . Once We are done with the recording sessions in ranorex two files are generated one is for user to change code file and one is auto generated by ranorex . In that .cs file on clicking right-click we get file mode where inside that we have multiple options like BAT C++.net java xml HTML coco php etc . What is the use of that language selection in file mode . whereas scripting in ranorex is found to be only C and vb . .. . Answer : Ranorex File Mode is just to be able to change the editor color-scheme text color is based on keywords and code syntax . Usually file content-type is determined by the file extension . This option is more useful when file content can t be determined using the file extension . For example this option can be used to tell Ranorex editor that a .dat file containing xml content in a particular project . Comment : I forgot to mention a Ranorex project can contain any type of file script and the Ranorex editor can be used to edit other file types . In our projects we use Ranorex to edit deployment scripts batch files and include them directly inside our Ranorex project for convenience .", "Question : For my automated-tests everything works fine except only when it is in English and this script needs to be able to run for Spanish versions of the same application too . I am not even sure if this is possible but is there some way of making Ranorex do some sort of translations or some sort Currently validation doesn t work because obviously the text is in a different language how can I get around this If it is even possible . .. . Answer : Usually when testing an application which can be represented in different languages I would suggest using language independent properties in the RanorexPath for example an automation id if available .

Does a TestMethod in coded ui represents a test case Comment : What does the diagram in your question mean Please explain how it should be interpreted . A method with the TestMethod attribute is a test case . .. . Answer : We have faced the same problem and resolved it by first making an assumption . A Microsoft TestMethod is not corresponding to a Ranorex Test Case it is a Ranorex Run Configuration as defined in the test suite . A Run Configuration comes with configuration . As you may already know on the command-line it is possible to execute a Ranorex Test Case or a Ranorex Run Configuration but it is better easier to execute a Run Configuration since it comes with context and also most development can be done by non-programmer from within Ranorex .

If this method does not suit your setup you can probably invoke Ranorex Test Cases directly in test method and do whatever sequence you wish to replicate as shown in your test suite but that would be more complicated and involve more maintenance IMHO which must be done by programmers . Hope this helps Hugo Comment : Hi actually I m not doing an integration with Ranorex . I m just evaluating VS coded ui . I want to know if whatever features available in Ranorex can be done in VS and how if possible . Comment : Like I always answer to testers in our test automation team : Anything can be done It s just time and money that limit us . In other words using code you can quite easily reproduce what is represented in the test suite screenshot you provided but that would require programming skills.. . This is the reason we chose to develop our test automation using Ranorex no or basic programming skills required .", "Question : I m trying to do some automation but I m having trouble identifying some elements . Is there any way of getting the WPF base path in an application through an element finder like snoop I m using ranorex spy which is pretty horrid . .. . Answer : I dont t understan what the problem is with Ranorex Spy The base path of the application looks usually similar to the following path and can be found on the very beginning of the RanoreXPath in Spy after tracking an element within the application .", "Question : I have a relatively big web app is written in AngularJS . Our automation is using Ranorex to run BDD tests . We are in a constant dilemma on how to enable the Ranorex tests to find UI elements effectively . Currently we re mainly using a custom attribute for it testid e.g . div testid done btn but in some cases it performs very poorly not sure whether it s because the querying XPaths aren t optimized or some other Ranorex configuration . Using the id attribute is way faster but it just doesn t feel right to use it for automation . Besides keeping it unique might require some coding in some cases e.g . when using ng-repeat . Is using id just for automation purposes OK or is it a bad practice Why Any way to make Ranorex relate to custom-attributes such as testid differently so that it ll be found faster I ve read about Ranorex Weight Rule http : www.ranorex.com support user-guide-20 ranorexpath-weight-rule-library.html but couldn t find a way to define custom-attributes . .. . Answer : The quick answer : YES Use the Id s . I m not actually familiar with the dilemma you are facing . Can you please further explain the reasoning behind not wanting to use the id-s . .. . .. . And if you face issues related to id s not being unique in some cases you can combine different elements to the path eg . @id save btn and @innerText Save . Usually if you can improve the speed and stability of your automation with no visual or functional expense - do it . Comment : generally we thought that using id which is an attribute with meaning and is part of the HTML specification just for automation might not be the best idea so we preferred using a custom attribute . But as written this showed bad performance . Thanks :", "Question : I ve been experimenting with Selenium to some success however it s slow going . Ranorex as I ve used briefly in the past can put a simple suite of tests together rather quickly . However I m concerned about scale-ability . The website I m interested in automating testing for is fairly large in terms of how much test-coverage it requires . Watching video tutorials on modulating test steps gives me the impression that Ranorex isn t designed to really support a larger size web-app with detailed testing parameters . How big are the projects you use Ranorex for and how do you manage your tests and suites How do you keep it organized .. . Answer : Ranorex provide Suite and Group module where you can add multiple test casew grouped them . Also it provide configuration at suite level where you can grouped set of test cases from suite . So when you run that particular configuration from suite then selected test cases will execute . I have used Ranorex where we have approximate 1000+ test cases scenario based . Let me know if you need more information . Thanks Sadik", "Question : null .. . Answer : Ranorex Experts .. . .. .

But in the API docs all I can see is XPath RanoreXPath based object identification .", "Question : Visible in the context of UI-testautomation can mean two different things : .. . .. . 1 . Visible anywhere on the website . You can see it immediately or after you scroll .. . .. . 2 . Visible in the viewport which means that you can see the element without scrolling . In the Ranorex documentation http : www.ranorex.com Documentation Ranorex html P Ranorex Adapter Visible.htm the definition isn t clear regarding this . So what is in Ranorex the exact definition for visible .. . Answer : The visible attribute itself just means that it is possible in general to bring the element to the visible region . If the visible attribute of a parent element is set to false it might also not be possible to make the element itself visible . Comment : Ranorex official support told me that this answer is correct", "Question : I am using Ranorex to do automation tests against our application which consists of several 3rd party controls like the DevExpress GridControl . In most cases the grid rows are accessible . However it can happen that the grid rows are not accessible for about 1 minute only if you play with Ranorex Spy for a some time . Do you know where the problem could be .. . Answer : That sounds strange . Does that mean that the grid can be recognized after one minute and that only happens with Ranorex Spy . What if you run the test You wrote that it happen sometimes did you already find out when Is there a difference when using the external Spy and the Spy which is integrated in Ranorex Studio", "Question : I am Using the following code to read a excel file by using ranorex tool . i want to know whether messageBox.Show and Report.Info has the same functionality as i have to replace the c attributes with ranorex . .. .

Tell me more.. . http : www.ranorex.com Documentation Ranorex html M Ranorex Report Info.htm Comment : I don t think you can use Ranorex to close a popup that is generated by the Ranorex runner itself As mentioned messagebox.show is modal thus Ranorex runner will be blocked on the message box show function until the OK button is clicked . I am not sure the popup watcher would work in this condition . Anyway I ve had bad experience with popup watcher and would not use them . They did not seem to work consistently and I avoid them for now.. . Comment : @Sup3rHugh Incorrect . OP is using Winforms namespace Comment : Sorry OP what Comment : @Sup3rHugh MessageBox is WinForms .

Would it be possible to share to us the steps you made and maybe a sample code . Can you highlight how you run multiple test case in Ranorex . Thanks .. . Answer : I have used TestRails API binding for .NET http : docs.gurock.com testrail-api2 bindings-dotnet for writing a simple C file in Ranorex . The idea is to have a test run with tests in TestRail and Ranorex posting to TestRail about the success of the test execution of these tests . This posts the result for one case to Ranorex therefore the add result for case method . The runID is a parameter I give in command-line when I execute the suite and each test case in Ranorex corresponds to one test case in TestRail and must hold the test case id . Take a look at http : docs.gurock.com testrail-api2 start about what possibilities the TestRail api offers" ] }

Now If I remove load from printVar row Val - load and do printVar row Val it will again return me the OCI-Lob Object . To get OCI-Lob Object We do need Oracle Select Query in addition we can pass XMLAttributes Elements with getClobVal or any function . But We can t parse XML and convert it to OCI-Lob Object as it always interact with the Oracle Database Server . .. . .. . So to run the PHP Unit test what I did was I took the XML and Converted that to an OCIMockObject Which Will have all the XML Values and parse it to the function .

Answer : Oracle instant client is a small subset of the full thick client . It includes the OCI C-libraries JDBC and ODBC which makes is possible for programs written in C Perl Python Java Scala and so on to connect to an Oracle database server . Instant client dont include familiar Oracle tools like sqlplus sqlldr exp imp and more .

The only thing i could find is link-to Oracle support site which i can t access . Please clarify my doubts . Many thanks in advance . .. . Answer : Briefly : .. . .. . OCI is C API libary . There is also C++ library called OCCI but I do not recommend it you can have problems with C++ ABI changes dialects on various compilers .. . .. . Both Instant and thick Oracle client contain OCI library OCI.DLL or linclntsh.so . The one provided by Instant client is more-or-less self-contained . e.i . it does not depend on other libs provided with Oracle client compare output from ldd on Linux or depwalk on Windows . Both also contain necessary headers .. . .. . The C API in both clients is practically identical . The only exception I recall is a set of supported database native characters sets . InstantClient supports only UTF8 ISO Latin1 and ASCII . thick client also contains a library named libxml.a which is needed when you want to use datatype SYS.XMLTYPE . This library is not for some unknown reason bundled with InstantClient .. . .. . thick client also contains some handy diagnostic tools like tnsping .. . .. . InstantClient is very easy to setup . Users simply unpack a single .zip file . Do not have to set ORACLE HOME PATH LD LIBRARY PATH env . variables . You simply dlopen one library file and that s all . InstanctClient can work without tnsnames.ora although it supports it instead of that you can use jdbc-like EZCONNECT .. . .. . Both types of clients may not be re-distributed unless you re Oracle businesses partner . So you must not embed these driver s lib in your application . Each user must download then separately . So far I have not found a C API way how to distinguish InstantClient OCI.DLL libary . There is InstantClient specific section in Oracle Call Interface Programmer s Guide .. . .. . I recall there might be some problems with InstantClient when you set ORACLE HOME env . variable and it s values ends or does not end with slash", "Question : I have a XML as below - .. . .. .

Hope you understand my question . Any suggestions on this would be appreciated . Thank you . .. . Answer : To get OCI-Lob Object We do need Oracle Select Query in addition we can pass XMLAttributes Elements with getClobVal or any function . But We can t parse XML and convert it to OCI-Lob Object as it always interact with the Oracle Database Server .

Any ideas if it is possible and how to change the osuser value using OCI Cheers .. . Answer : It appears that it is not possible to set the OS User with the OCI driver . The Oracle documentation http : docs.oracle.com cd E18283 01 appdev.112 e13995 oracle jdbc OracleConnection.html CONNECTION PROPERTY THIN VSESSION OSUSER for Java highlights that setting the OS User is only possible when the oracle Java Thin driver is used .", "Question : I am working on an application that uses Oracle OCI to connect to the Oracle database server . The application allows the user to change their Oracle password and uses Alter User xxx Identified By to perform this . However this transmits the user s new password in clear text over the network we cannot use Oracle SSL to encrypt network traffic . I have found that Oracle recommends using the PASSWORD command in SQLPlus rather than ALTER USER one reason being that the new password encrypted . Does the OCI method OCIPasswordChange also encrypt the new password when it is transmitted over the network This is using Oracle 10 and 11 . .. .

Is there a way to set this to 0.XXXXXX or to any other format without modifying every query to use to-char explicitly Perhaps through some session parameters .. . Answer : There is no way to do what you re asking globally short of modifying php oci-extension source code . The reason for this behavior is because oracle oci omits 0s in results and php converts all results from oci to strings without performing any casting depending on column datatype . Even results in SQL Plus omit 0 by default and SQL Plus formatting has to be invoked with set numformat to customize column formatting and prepend 0s . There is currently no alter session parameter you can set to change this behavior . Most common way to work around this is to use a wrapper around your queries and check for numeric columns with is numeric and then format the numeric column values with number format or sprintf . Hopefully your application already uses a wrapper around stock php oci functions so you can make the change in one location .", "Question : When using Pro C a embedded SQL preprocessor from Oracle for C-Code or OCI I noticed that the connect init routine installs some signal handlers .

Thus I am interested in : .. . .. . the motivation - why are those signal handlers installed by Oracle how to disable them - at least for signals that yield a core-file by default - because for my use-case I want a core under those circumstances during development or a reliable and informative exit status in production .. . is it safe to overwrite the Oracle signal-handler via e.g . act.sa handler SIG DFL sigaction SIGABRT act 0 what are the disadvantages of resetting SIGABRT SIGSEGV and friends to SIG DFL after connect Comment : Best solution would be not to use buggy non-thread-safe software like Oracle . .. . Answer : Signal handling and diagnostic framework considerations : the OCI diagnostic framework installs signal handlers that may impact any signal handling that you use in your application . You can disable OCI signal handling by setting .. . .. . in the sqlnet.ora file .

Answer : To build OCI applications you need the SDK which includes the header-files etc .

Comment : That link explains how to use OCI8 not PDO . They re different and unrelated extensions . .. . Answer : You should note that there re two completely different PHP extensions designed to connect to Oracle databases : .. . .. . OCI8 http : php.net oci8 is the extension developed by Oracle Corporation . It s actively maintained and it s the recommended way to interact with Oracle . PDO OCI http : php.net pdo oci is the PDO driver developed by the community . It was never finished and it s actually kind of abandoned thus the EXPERIMENTAL warning displayed in the documentation . Both contain the OCI Oracle Call Interface term because both make use internally of the OCI API provided by Oracle . As such you need the Oracle Instant Client no matter what library you choose . But you then need to install the corresponding PHP packages . In your case you re installing OCI8 and then trying to run PDO code .", "Question : null .. .

Thanks for solution advice . .. . Answer : The widgets of SWT and draw2d are quite different from each other . SWT just provides a platform to draw2d where something can be drawn . Hence for SWT there is no way to differentiate between a draw2d Label or say a draw2d Connection . All it understands is that something by a Figure which may have any number of figures as it s children will be painted in some specified area painted that s it no semantics to it .

What I need is working except scrollbars . In draw2d I get scrollbars provided by org.eclipse.draw2d.ScrollPane and in GridTreeViewer I get scrollbars from JFace . I am not sure why but scrollbars look different I would expect them to look the same since they are calling OS s native controls if I am not mistaken Is there a reason why scrollbars look different and is there a way downgrade JFace s scrollbars to look like draw2d s Perhaps there is mistake in setting up ScrollPane s scrollbars Here is the screenshot this is on Ubuntu 13.04 : .. . .. . enter image description here http : i.stack.imgur.com PRs4j.png .. . Answer : There is no mistake on your side . Leftmost tree has a custom-drawn scrollbar I assume that s Draw2d tree and rightmost tree shows native scrollbar I guess those are the ones you call JFace . You can notice that most applications outside of Eclipse show scrollbars like the JFace ones . That is if Ubuntu overlay scrollbars are enabled . There is no easy fix for this . IMHO you could try to get in Draw2d sources and try disabling their custom-drawn and replacing them with native ones from SWT . Or you could use a custom tree instead on Nebula control.. . Please note that JFace toolbars will look drastically different on Mac OS X or Windows will have different size and such . And the users will expect them : Comment : Thanks @Eugene Yeah that s what I would expect . Why did draw2d developers decide to roll their own styling Isn t the whole notion of SWT is to rely on host OS for controls Comment : Draw2d is meant to be lightweight . It is meant for creating diagrams where you work with figures pretty much as you would do with controls - and Draw2d manages Z order clipping and such . They did not want to have every figure to be backed by an OS control - this would consume to many resources on bigger diagrams AFAIK Windows even has a limit on a max number or controls thus they custom draw everything in their viewer . Comment : I get that but I wish there was a way to override styling in favor of OS s control styling that is if it s possible . Comment : It is not possible feasable if you are targetting multiple OSes.. . E.g . Mac OS X has had - not sure if it s still there some controls pulsing when they are selected - custom-drawn controls will immediately look fake . That is one of the problems with the likes of SWING and Qt . Note that you can try overlaying native control e.g . add it on the same parent as your tree and position on top of the tree carefully updating the bounds - but that is generally a waste of time .

I am guessing that the draw2d library and the ui-bootstrap-tpls for the according and perhaps other templates conflict in someway either in attribute naming and or css . Thank you for your help . .. . Answer : After much searching it seems that the issue revolves around SVG s-function getBBox Get Bound Box . The object is being created to fast . Thus an injection of a short timeout in this case 20ms did the trick . Changing .. . .. . to .. . .. . did the trick . WELL ---- WRONG Or not completely right .. . .. . After getting some sleep it turns out the setTimeout or the angularjs-timeout function only fixes this issue IF is-open true is set on the accordion . If not set or if it is on another accordion then the fix fails . It seems that the Accordion must be open AND the timeout used for the text label to be correctly rendered . More research to come...... . .. . .. .

Answer : You should be able to dynamically change your DOM node of your canvas by setting the width and height manually . Here we have a width of 2500px and a height of 2500px .

It actually answers your actual question . canvas.clear is a function written in draw2d touch which clears the canvas . It s essentially a wrapper around the raphael.js functionality but takes care of draw2d touch things like clears events and such . Comment : Yes i was using canvas.clear but what i was doing needs a soft canvas.destroy that not exists but with the solution you give its good now . When we use canvas.clear its only destroys objects in the canvas and canvas.destroy destroy objects canvas Raphael paper.remove and events and we can t recreate it again . and thx again Comment : Gotcha chief.. .", "Question : null .. .

We are building a Tree of the nodes with Connections between a parent and a child node . The number of figures in the canvas are of the order of 10000 just the Node Figures there are about another 10000 Connection figures too that I am not counting . I am attaching a part of one of our diagrams in Image : .. . .. . enter image description here http : i.stack.imgur.com M8YwL.png .. . .. . The problem is this : the nodes in the tree can be collapsed or expanded . When the number of Nodes in the Tree are of the order of 1000-2000 then the Collapse Expand takes place momentarily . However when the node count goes higher it takes more and more time to Collapse Expand any particular node which is irritating . I have written some sample code to see if the problem is with our code or that draw2d performance degrades in general with more number of widgets . The same problem exists within the sample application which indicates that we may have to do some optimizations within the draw2d codebase itself . I made a View in Eclipse to demonstrate that . The code of the same is attached below . Try to expand collapse figures in the View by clicking on the x or buttons it ll take time won t occur instantaneously . Can anyone please provide some pointers as to how this problem can be solved .. . Answer : I figured it out . I am posting it here in case anyone faces similar performance issues . I received help in this regard on the Eclipse forum . The link and full code is provided at the eclipse forum here : http : www.eclipse.org forums index.php m 1064195 Comment : +1 but please post the solution here . Links tend to be dead after a certain amount of time which would render your answer useless . Comment : The Solution for the Problem is this : When a large number of widgets are added to a same parent such a problem will occur because every time there is even a slight modification in any of its children a revalidation is performed for all the siblings . The way to deal such situations is to use some kind of Paging i.e . Divide children in a number of panels and then add them to the parent . This will reduce the amount of revalidation work significantly and hence there would be a marked improvement in the overall performance . The link I provided contains a ZIP file which is sample code . Comment : I am not able to reach the zip file . Can you post it on dropbox or something similar", "Question : Im trying to make an arrow joining a rect and a path triangle . This is my code : .. . .. .

Answer : You could use different test bundles and include exclude what you want . What I mean is creating your own custom test targets bundles and using the Xcode Test Navigator . So for example creating a MyUnitBundleTests target and a MyPerformanceBundleTests target . They would be two separate test bundles where you choose to included exclude classes methods etc . The Test Navigator displays a hierarchical list of the test bundles and associated classes and methods etc included in a project . You can enable and disable test bundles classes and methods selectively by Control-clicking the items in the test navigator list and choosing Enable or Disable from the shortcut menu thereby enabling or disabling the items in the scheme .

I currently have two separate projects that I switch between to build the library .

I would like to avoid having to manually add a new file to each separate project individually when I need to do so . Thoughts .. . Answer : 1 . Open your iOS project . 2 . Choose File New Target from the menu bar . 3 . Click Framework Library in the OS X section . 4 . Choose the Cocoa Library target . 5 . Enter a name for the OS X version of the library . It must be different than the iOS library name . Example : MyLibraryOSX . 6 . Maybe change the type to Static . 7 . Click Finish . 8 . Select your project itself in the Project Navigator . 9 . Click on the new OS X library target in the TARGETS section . 10 . Click on the Build Phases tab . 11 . Open the Compile Sources section . 12 . Note that Xcode automatically created a .m file with the same name as the OS X library target . You may wish to delete this from your project . 13 . Add your library sources to the Compile Sources section . Xcode normally creates a scheme for the new target automatically . If you have turned Autocreate schemes off for this project you need to choose Product Manage Schemes and create or ask Xcode to autocreate the scheme for the new target .

In the test configuration for the unit test scheme I selected debug build and for the performance test scheme I selected release build . If I run each scheme individually I get a debug build and a release build respectively . If I create another scheme that runs both of these schemes then that new scheme will have its own build configuration . If I set a build configuration of debug for this new scheme then I will get a debug build for my performance tests as well . .. . Answer : There might be a way to achieve the desired behaviour but it is more of a hack . The main problem I see is the desired build configuration for the test action of the scheme . Since the build configuration applies to all targets in the scheme you need to find a way to trick Xcode into building your target with both Debug and Release configuration . That being said here is the idea : .. . .. . 1 . Export the release configuration for your target into an xcconfig file xcodebuild -scheme schemeName -showBuildSettings release.xcconfig and make sure it only contains the release settings .. . 2 . Create another target for your performance tests that builds the same source files .. . 3 . Set the debug configuration of this new target to the aforementioned xcconfig file of the release configuration that is basically the part where we fool Xcode .. . 4 . Add the original and the newly created target to the build action of your scheme and add the test bundles assuming they reside in a separate test bundle .. . 5 . Select the debug build configuration for the test action . If you test your scheme it should now build the sources in both debug and release and should run your unit tests on the debug build configuration and the performance tests on the release configuration . The setup is a bit fragile as you need to add new source files to both targets . You should be able to automate the process using a ruby script and the xcodeproj gem though .

An external SDK we re implementing requires its app key to be set in the Info.plist but requires separate keys for debug enterprise distribution and release schemes .

What I m trying to avoid is repetition of all keys since it will make adding new ones in future a hassle . Is this possible .. . Answer : There are a few different things you might try . Xcode run script executed before app build This is a script that is automatically executed before you build . Let s say the 3 duplicate plist files are called InfoA.plist InfoB.plist and InfoC.plist which are all exact duplicate . When you build the project the contents of InfoA.plist are duplicated to InfoB.plist and InfoC.plist . This would require some knowledge of writing a shell script to do that but the script is fairly simple . You could duplicate and rename the files in the script . Or you could use command-line tools to copy the contents of the main file to the duplicate files . Two command-line utilities you can use to modify the contents of plist files are plutil and https : developer.apple.com library mac documentation Darwin Reference ManPages man8 PlistBuddy.8.html .

We were using facebook-login to authenticate with our own services on the enterprise version . The FB SDK would take over and kick out to a web view or the fb app depending on it s own logic . Critically - we were using the same facebook app configured on their developer site .

In most cases this was the app-store version NOT the enterprise version .

My questions are : .. . .. . does setting the xsi : type mean I can set the root element s name to any value I like without impacting XSD validation outcome which tool is right Xerces or xmllint .. . Answer : Unlike some other validation languages XSD does not define a single simple Boolean-valued concept of validity against a given schema . So the answer to your questions is it depends . XSD defines several ways in which an XSD validator can be requested to assess the schema-validity of a document it does not forbid others : .. . .. . type-driven validation : we can specify a type definition in the schema and a node in the document and ask is this node valid against this type In that case an xsi : type attribute on the element node we specified will not override the type we specified . I almost said it will have no effect but it can : if xsi : type is specified its value must name a type actually present in the schema if there is no top-level type with the indicated QName the xsi : type attribute is invalid and its parent will be invalid . element-driven validation : we can specify an element declaration in the schema and an element node in the document and ask is this element valid against this declaration In that case the element instance will be validated against the element declaration we have specified . An xsi : type attribute on the element node we specified will in the absence of errors override the type specified . If the type specified in the instance cannot be found in the schema or if it s found but is not validly derived from the declared type or if some other rules are violated then there will be validity issues . attribute-driven validation doesn t apply in the case you re talking about it involves specifying an attribute declaration in the schema and an attribute node in the instance and asking is this attribute instance valid against this attribute declaration . lax-wildcard validation : we can specify a node in the document instance and ask is this node valid against its declaration in the schema if any In lax-wildcard validation the expectation is that at the application level a valid node counts as success an invalid node counts as failure and a node whose validity is unknown because there is no such declaration counts as success . In this case an xsi : type attribute on the validation root will be taken as identifying a governing type definition . strict-wildcard validation : this is essentially like lax-wildcard validation except that if the validity of the validation root is unknown because there is no governing element declaration or type definition then it counts at the application level as failure . Many command-line tools default to lax-wildcard validation of the outermost element in the XML input : they look in the schema for a top-level declaration for it validate against that declaration if they find one and are silent if they don t find one . This leads to the bizarre consequence that if no declaration is found owing to a namespace error or for whatever reason it may look to the user as-if the document were valid instead of merely being not know to be invalid . In the cases you describe Xerces appears to be defaulting to lax or strict wildcard mode finding the xsi : type declaration and correctly declaring the document valid . The xmllint processor appears to be defaulting to a different mode slightly different from any of those described by the spec in which a top-level element declaration is sought and an error message is issued if it s not found . That s very similar to strict-wildcard validation mode as defined in the XSD spec but it appears to exclude the possibility of validating against a type specified in the instance by an xsi : type attribute . Under those circumstances xmllint quite correctly reports that the root element of the document is not valid against any top-level element declaration in the schema . Now we can extend the It depends answer more informatively . does setting the xsi : type mean I can set the root element s name to any value I like without impacting XSD validation outcome It depends on what kind of validation you re performing . Cases where the answer is yes include these : .. . .. . The name of the root element never has any effect on validation episodes that start from some other node so in all cases where you request validation of an attribute or of an element other than the root element you can indeed set its value to whatever you like . In cases where you request type-driven validation or cases where you request lax or strict wildcard validation and the schema has no top-level element declaration matching the root element the name of the root element will have no effect on schema-validity assessment . Cases where the answer is no : .. . .. . In cases where you request element-driven validation the name of the root element must match the name given on the element declaration . In cases where a you request wildcard validation and b the schema has a matching element declaration then the name of the root element will have an effect on schema-validity assessment because it will determine which element declaration is selected as the governing element declaration which will in turn determine whether the instance-specified type is or is not validly derived from the declared type of the element . which tool is right Xerces or xmllint It depends on how you define rightness . The XSD spec defines several ways of requesting validation and in 1.1 assigns the names given above for them but it very clearly does not attempt to define user or application interfaces as part of the standard so there is no right or wrong with respect to the exact formulation of the validation question a schema-validator assumes when you call it its default validation routine . Comment : Impressively thorough and well expressed answer regarding a disappointingly convoluted decision procedure . Comment : After reading the answer I wonder whether the equivalent of an international tribunal for crimes against humanity in the field of software technologies should be established and make sure it prosecutes every single person even remotely related to any organization involved in XML specifications from committee chairs down to unsuspecting contractors providing janitorial services . Comment : I m sorry you feel that way . The XSD spec is unnecessarily hard to read and the WG was unnecessarily unhelpful to people who want a simple story you can always provide a simple story as the default and allow other stories as options but I think distinguishing between validation against an element declaration and validation against a type definition is actually a good idea . Many implementors have not done very well with the freedom and responsibilities assigned them by the spec that s only partly the spec s fault .", "Question : When I have an example CCD should I use : .. . .. . 1 .

Answer : Option A is more recommended which involves parsing the XML document with a DocumentBuilder http : docs.oracle.com javase 1.5.0 docs api javax xml parsers DocumentBuilder.html that has a specific CCD schema source and then checking for validation errors . I recommend looking at the XMLValidation class in the SchematronValidator http : gazelle.ihe.net content schematron-based-document-validator project the validXMLUsingXSD .. . method does what you are describing . There are several places to find an XSD for valid CCD XML but if you don t know where to start you can find most of the XSDs for CDA CCR schemas at Microsoft HealthVault .

Answer : DTD is the acronym for Document Type Definition . This is a description of the content for a family of XML files . This is part of the XML 1.0 specification and allows one to describe and verify that a given document instance conforms to the set of rules detailing its structure and content . Validation is the process of checking a document against a DTD more generally against a set of construction rules . The validation process and building DTDs are the two most difficult parts of the XML life cycle . Briefly a DTD defines all the possible elements to be found within your document what is the formal shape of your document tree by defining the allowed content of an element either text a regular expression for the allowed list of children or mixed-content i.e . both text and children . The DTD also defines the valid attributes for all elements and the types of those attributes . Comment : Hello @Rachna .

Answer : Basically a parser MUST expand entities to validate a document see 4.4.3 in XML recommendation http : www.w3.org TR xml include-if-valid since your entities may include some markup and build up a valid document . So yes the problem may occur during validation of the XML file .", "Question : I m generating xml files that need to conform to an xsd that was given to me . What s the best way to do this .. . Answer : If you are generating XML files programatically you may want to look at the XMLBeans http : xmlbeans.apache.org library . Using a command-line tool XMLBeans will automatically generate and package up a set of Java objects based on an XSD . You can then use these objects to build an XML document based on this schema . It has built-in support for schema validation and can convert Java objects to an XML document and vice-versa . Castor http : www.castor.org and JAXB http : java.sun.com developer technicalArticles WebServices jaxb are other Java libraries that serve a similar purpose to XMLBeans .", "Question : I m generating xml files that need to conform to an xsd that was given to me . What s the best way to do this .. . Answer : The Java runtime library supports validation . Last time I checked this was the Apache Xerces parser under the covers . You should probably use a javax.xml.validation.Validator http : java.sun.com j2se 1.5.0 docs api javax xml-validation Validator.html . The schema factory constant is the string http : www.w3.org 2001 XMLSchema which defines XSDs . The above code validates a WAR deployment-descriptor against the URL http : java.sun.com xml ns j2ee web-app 2 4.xsd but you could just as easily validate against a local file . You should not use the DOMParser to validate a document unless your goal is to create a document object-model anyway . This will start creating DOM objects as it parses the document - wasteful if you aren t going to use them .

I just want an XSD that validates the bare minimum requirements that the document must meet . Is there a way to do this EDIT : .. . .. . marc s pointed out below that you can use xs : any inside of xs : sequence to allow more elements unfortunately you have to maintain the order of elements . Alternatively I can use xs : all which doesn t enforce the order of elements but alas doesn t allow me to place xs : any inside of it . Comment : Some good answers and discussion but I have to go with Abel s as it was so detailed and also explained WHY what I was looking for didn t exist . .. . Answer : You should be able to extend your schema with the xs : any element for extensibility - see W3Schools http : www.w3schools.com Schema schema complex any.asp for details . When you add the processContents lax then the .NET XML validation should succeed on it . See MSDN docs on xs : any http : msdn.microsoft.com en-us library ms256043.aspx for more details . Update : if you require more flexibility and less stringent validation you might want to look at other methods of defining schemas for your XML - something like RelaxNG http : www.relaxng.org . XML Schema is - on purpose - rather strict about its rules so maybe that s just the wrong tool for this job at hand . Comment : while that almost works the order becomes important . GivenName and SurName must be the first and second elements respectively...at least I think that s the effect of xs : sequence . I could change it to xs : all . But then I can t use xs : any.. . Comment : which tells me that XSD is inherently broken . XML is supposed to be eXtensible . Order of elements isn t supposed to matter . So first why can you define a sequence Second why can t we write extensible XSDs Comment : I realize a sequence is a sequence I think it s bad that it exists as it violates the basic principle of XML extensibility . Aside from that why can t I define an XSD that is truly extensible . Using xs : sequence and xs : any sort of works but I have to ensure that the sequenced elements are first and appear in order.. . which shouldn t matter given the nature of XML . Comment : @Chad : Maybe if you really need this kind of flexibility XML schema is just the wrong tool for the job . Have you ever looked at RelaxNG relaxng.org http : www.relaxng.org Comment : I need to define a minimum level of conformance . Nowhere did I say anything anywhere anytime . I need to define a minimum document and allow it to be extensible . If you need to define a sequence of elements in your XML I would say you should define it IN the element with a sequence attribute . Relying on the order of the elements in the document feels like an affront to the essence of XML .", "Question : I wasn t aware of a difference but a coworker says there is although he can t back it up . What s the difference if any .. . Answer : W3C in the XML specification has defined certain rules that needs to be followed while creating XML documents . The examples of such rules include having exactly one root element having end-tag for each start-tag using single double quotes for attribute values and so on . If an XML document follows all these rules it is said to be well-formed document and XML parsers can be used to parse and process such documents . Document Type Definitions DTDs or XML Schemas can be used to define the structure and content of a specific class of XML documents . This includes the parent-child relationship details attribute lists data type information value restrictions etc . In addition to the well-formedness rules if an XML document also follows the rules specified in the associated DTD Schema it is said to be a valid XML document . All valid XML documents are well-formed but the reverse is not always true . Well-formed XML documents do not necessarily have to be valid .", "Question : i have to implement schematron validation for my xml xbrl files.i have searched and tried some libraries such as NMatrix and Saxon based on msdn . http : msdn.microsoft.com en-us library aa468554.aspx .. . .. . -NMatrix schematron validation not validate my xml i mean it is not giving any exception . -Saxon free edition is not validate xml through sch files .

Main method : Comment : Why did you tag the question with xslt Comment : @MathiasM ller because I validate using XSLT2 PHSchematron supports XSLT and Pure Schematron validations .. . Answer : Testing against the general ISO Schematron rules your Schematron document is correct except for the targetNamespace attribute . Having a default namespace in it xmlns .. . does not make much sense either since all of the elements are prefixed . Schematron .. . .. . Then the Schematron is fine but there is a bunch of problems with the XML Schema . First of all the namespaces in the XML Schema document are different . The Schematron file has http : purl.oclc.org dsdl schematron while in the XSD it is http : www.ascc.net xml schematron . This is most likely because you are using an age-old XML Schema for an older version of Schematron .

All of this can be fixed by modifying your XML Schema the following is a version that works : .. . .. . XML Schema .. . .. . But please keep in mind : this XSD document is outdated and does not reflect the latest changes to the Schematron specification . It is very likely that there will be other problems with it .

Another way to put it is that well-formed XML is syntactically correct it can be parsed while valid XML is semantically correct it can be matched to a known vocabulary and grammar . An XML document cannot be valid until it is well-formed . All XML documents are held to the same standard for well-formedness an RFC put out by the W3 .

Answer : I think the easiest way to understand shadow DOM is by example : .. . .. . .. . div .. . input type range .. . div .. . .. . Your DOM for the above code will look exactly as you d probably expect it : .. . .. . But what your browser renders is something else : There s a horizontal line and a thumb or knob or whatever you call it . So internally the input has some child elements but they are not exposed through the DOM : .. . .. . But as I already wrote : Those are not exposed through the DOM so they are hidden to you your CSS your JS this is not entirely true browsers can give you some access for example Webkit-based browsers allow you to manipulate the appearance of the thumb in CSS via the -webkit-slider-thumb pseudo-element . On the other hand these elements need to be in the DOM somewhere to be rendered by the browser and that s where shadow DOM comes in : Internally the browser replaces every ocurence of input type range in the DOM by the tree .. . .. .

A good example is the video tag many of the controls could be implemented with divs and buttons but you as the user you do not have access to those internals . The internal representation is not available to code outside the custom component unless you expose it through the shadow DOM or custom methods . See html5rocks.com en tutorials webcomponents shadowdom http : www.html5rocks.com en tutorials webcomponents shadowdom Comment : Yes the shadow DOM is not really part of the tree from the point of code l view of the caller it s hidden behind the implementation and that s the whole point .. . Answer : It looks like the quote came from this article titled : What the Heck is Shadow DOM https : www.w3.org TR 2015 WD-shadow-dom-20151215 shadow-dom-example .. . .. . The shadow DOM is part of the DOM but a virtual DOM is a hidden copy of the DOM . Sorry about the earlier confusion with virtual DOM . From reviewing this W3 Spec https : www.w3.org TR 2015 WD-shadow-dom-20151215 shadow-dom-example again it appears that the shadow DOM is simply a reusable DOM fragment . The browser will see it will render it s contents . This specification describes a method of combining multiple DOM trees into one hierarchy and how these trees interact with each other within a document thus enabling better composition of the DOM . This technology has been around since at least 2006 when I started using .innerHTML templates inside of JavaScript to build reusable DOM fragments . It s not new technology . It s simply being documented in 2015 by the W3C as an official specification . What is interesting are these CSS attributes pseudo-selectors which operate on the Shadow DOM but aren t part of the Real DOM . They are described at the bottom of the Composed Trees section https : www.w3.org TR 2015 WD-shadow-dom-20151215 composed-trees of the W3 Spec https : www.w3.org TR 2015 WD-shadow-dom-20151215 shadow-dom-example . : : shadow pseudo-element .. . .. . deep combinator which was replaced with a combinator or shadow piercing descendant combinator .. . .. . : : content pseudo-element .. . .. . : host pseudo-class and : host functional pseudo-class .. . .. . : host-context functional pseudo-class .. . .. .

The content is in the document the presentation is in the Shadow DOM . They are automatically kept in sync by the browser when it comes time to render something . .. . we can inspect the DOM see what the shadow DOM looks like . It looks like this where both CSS HTML can be encapsulated inside of a shadow DOM element which is hidden inside of a div tag . See : https : developer.chrome.com devtools docs settings-files show-shadow-dom.png .. . .. . It seems like the idea is to encapsulate the CSS HTML so that it doesn t spill out onto other areas of the page . Nor allow other existing on-page code to affect what is inside of that encapsulated code block . Older examples of this encapsulation would be hidden iframe tag which were designed to show ads but stop 3rd party ad code from breaking the JS on our really cool web pages .

What does it gives Why dont we use standard DOM instead of it except for styling scoping Comment : read this : glazkov.com 2011 01 14 what-the-heck-is-shadow-dom http : glazkov.com 2011 01 14 what-the-heck-is-shadow-dom and w3.org TR shadow-dom http : www.w3.org TR shadow-dom .. . Answer : It allows you to encapsulate functionality effectively putting it in a black-box . It means you can create reusable components whose inner workings aren t exposed this is impossible using standard DOM . As an example take HTML input elements . So say the file-type of input . To use it on an HTML page you simply add input-type-file and it works . You don t need to add any extra code or HTML or CSS to handle how it works it just does and you can t access the internal bits of it . If you were to write a piece of UI using HTML CSS JS that did the same thing it would be fairly complex . But the file input is just a single tag that you can use anywhere it always does the same thing . The web-component family of specs allow you to create your own elements that work in this way and the Shadow DOM is a critical part of this . You can create a new element like my-fantastic-file-input with its functionality encapsulated . It has its own internal DOM subtree but that subtree isn t directly accessible ditto with scoped styles . The new component does not expose its implementation details to the document . You can do most of this stuff using the DOM but the implementation will be wholly tied into the document application structure . With components you extract that implementation and you can reuse it pass it around publish it and let other people drop it into their applications documents and be sure it will work in exactly the same way anywhere . You cannot really do that as things currently stand by using the standard DOM . This is from 2011 and slightly out-of-date but it s a list of some possible use cases for the component model : http : www.w3.org 2008 webapps wiki Component Model Use Cases", "Question : Does implementing Shadow DOM in my projects will make them faster like virtual DOM that s used by React .. .

Comment : Thank you You just made it clear to me .", "Question : Does implementing Shadow DOM in my projects will make them faster like virtual DOM that s used by React .. . Answer : Virtual DOM .. . .. . Virtual DOM is about avoiding unnecessary changes to the DOM which are expensive performance-wise because changes to the DOM usually cause re-rendering of the page . Virtual DOM also allows to collect several changes to be applied at once so not every single change causes a re-render but instead re-rendering only happens once after a set of changes was applied to the DOM . Shadow DOM .. . .. . Shadow dom is mostly about encapsulation of the implementation . A single custom-element can implement more-or-less complex logic combined with more-or-less complex DOM . An entire web application of arbitrary complexity can be added to a page by an import and body my-app my-app but also simpler reusable and composable components can be implemented as custom elements where the internal representation is hidden in the shadow DOM like date-picker date-picker . Style encapsulation Shadow DOM is also about preventing styles being applied accidentally to elements the designer didn t intend to for example because the CSS or components library you are using changed a selector that now applies to other elements that use the same CSS class names . Styles added to components are scoped to that component and bleeding out or in of styles is prevented . Shadow DOM and performance .. . .. . Even though shadow DOM is not about performance in the first place it also has performance implications . Because styles are scoped the browser can make assumptions about some changes to affect only a limited area of the page the shadow DOM of a custom-element which can limit re-rendering to the area of such a component instead of re-rendering the entire page . This is the reason the deep and : : shadow CSS combinators which allowed to apply styles across shadow DOM boundaries were deprecated and are subject to be removed soon from Chrome other browsers never had them AFAIK . The mere existence of these combinators prevents the kind of optimization mentioned in the previous paragraph .", "Question : I m having issues using shadow DOM for one of the web-components paper-stepper and it requires the use of the shady DOM instead . I m not sure what the differences are and why that is the case . .. . Answer : Here s https : www.polymer-project.org a good explanation of why . Tl DR : .. . .. . Shadow DOM : .. . .. . Shadow DOM works by hiding the scoped DOM trees from the traditional tree walking functions and accessors childNodes children firstChild and so on . These accessors return only the elements in your scope . What this means is that it hides a layer of complexity from you . One of the examples I found online was about the video video tag . It explains how within it there are the video controls but those are abstracted away and you cannot see them . This is what the Shadow DOM does but for all the web components . Shadow DOM sounds nice but there are limitations .. . .. . It s a lot of code . It s slow to indirect all the DOM API . Structures like NodeList can simply not be emulated . There are certain accessors that cannot be overwritten for example window.document window.document.body . The polyfill returns objects that are not actually Nodes but Node proxies which can be very confusing . This is where shady DOM comes in . Shady DOM : .. . .. . Shady DOM is a super-fast shim for shadow DOM that provides tree-scoping but has drawbacks . Most importantly one must use the shady DOM APIs to work with scoped trees . By using the Shady DOM you now don t have an abstracted view of the components . You can see everything . However with Shady DOM you can examine how the tree would look like if Shadow DOM was being used instead by running this : .. . .. . So taking all this information into consideration on how the different DOMs work it seems like the paper-stepper web-component requires access to the whole tree to work properly . Since the Shadow DOM abstracts the inner elements you have to use Shady DOM or refactor the code in such a way that the inner elements don t need to be accessed from outside the abstraction .", "Question : This question is more aimed at user-created shadow DOM elements but for accessibility I ll use the date input type for this question : .. . .. .

Answer : int32 t is right in that Shadow DOM by definition is a way to fill a node with DOM that you want to hide from external sources Encapsulation http : en.wikipedia.org wiki Encapsulation 28object-oriented programming 29 . The point is that you as the component author get to choose exactly which parts will be exposed to outside CSS or JavaScript and which will not . Unfortunately you cannot create a public JavaScript interface to your Shadow DOM without using another bleeding-edge spec called Custom Elements http : www.w3.org TR components-intro custom-element-section . If you choose to do that it s as simple as adding custom public methods to your element s prototype . From these you can access the internals of your Shadow DOM see the third example here http : www.w3.org TR components-intro using-custom-elements-in-script . You can however expose hooks for CSS to access the internals of your Shadow DOM without using Custom Elements . There are two ways to do that : .. . .. . 1 . Pseudo-elements .. . 2 . CSS Variables .. . .. . Pseudo-elements .. . .. . Chrome and Firefox expose certain parts of their Shadow DOM to CSS through special pseudo-elements . Here s http : jsfiddle.net 6y9XT 3 your example of the date input with the addition of a CSS rule that only applies to the numerical part of the date field through use of the Chrome-provided -webkit-datetime-edit pseudo-element . Here s https : gist.github.com afabbro 3759334 a partial list of the available WebKit pseudo-elements . You can also just enable the Show Shadow DOM option in DevTools and look for attributes named pseudo . Component authors can also create their own pseudo-elements to expose parts of their Shadow DOM see the 2nd example here http : www.html5rocks.com en tutorials webcomponents shadowdom-201 toc-custom-pseduo . CSS Variables .. . .. . An even better way is to use CSS Variables which you can enable with Enable experimental WebKit features in about : flags in Chrome . Then check out this fiddle http : jsfiddle.net tBFXs 2 which uses CSS Variables to communicate to the Shadow DOM what color it should use for its theme .

Bottom line there is a polyfill that works on evergreen browsers here https : github.com Polymer ShadowDOM .. . .. . polyfilling of CSS features like @host are not in there yet coming soon .. . .. . So yes it s a hard thing to polyfill specifically because we have to invent secondary DOM trees .

If I put all this in a separate document and load it in via an iframe that s what I did for the facebook one I loose functionality because it tries to open the internal dialog inside the tiny iframe and it s unusable . Does anyone know a workaround that will allow you to use a Google Plus button within the shadow or at the very least a way to force the Google plus button to use a popup window for the comment dialog like the facebook button does I have found a few different polymer-elements made by other people for Google Plus buttons but none of them have templates and all add the elements in dynamically so there is no shadow-dom for that element but these elements dont work if they are already inside of a shadow-dom . In my case I have a share paper-dialog that I want to put these buttons in and the paper-dialog puts everything inside it s own shadow-dom . So I cannot eliminate shadow-dom from the application . Any help here would be greatly apreciated Comment : I have the same problem and tried the same things with you with no success . It s weird Google s own projects interfere with each other . .. . Answer : The trick seems to be with this.async see the following code for an example : .. . .. . https : github.com kunalnagar googleplus-badge blob master googleplus-badge.html .. . .. . Here are the pertinent parts :", "Question : What am I doing : .. . .. . I m coding my new app using stateless components with Angular 2 . What I want to do .. . .. . I want create generic component list which contain repeated widgets . There can be a few types of them : .. . .. . Simple item .. . Habit widget item .. . Another widget item .. . .. . So I can create list of habits list of users etc . and it s not always a table . It can be list of any widget . What am I doing to reach it . In my statefull view html I put list component and using Web Component s transclusion set what type of widget should be repeated inside . statefull view .. . .. . list component .. . .. . What s the problem with my solution .. . .. . I need to pass habits object to 2 different places what will cause difficult to find problem if I don t pass the same . Need to handle ngFor from the app view . So I m doing something what list component should handle itself . Conclusion .. . .. . Is there any better solution how I can put list component inside my statefull view HTML and decide there what type of widgets it should contain Of course I will create all this widgets . Comment : How is stateless and shadow DOM related to this all I guess you relate to content from Polymer which allows to project children into the view of another component - is that the case In Angular2 this is ng-content . I looked a bit into a similar list implementation . I think it s possible but not too easy . You could just use ngFor and just use a class that does the data-manipulation instead of a component . Otherwise I think a starting point is the TemplateRef class and the NgFor implementation . Comment : Shadow DOM is used by Angular2 like a new alternative to translusion . These components what I m creating are stateless . They should be stupid and generic . Comment : Ok then I assumed right . Shadow DOM itself isn t really about transclusion but the content or ng-content tag does it . Angular2 defaults to encapsulation : ViewEncapsulation.Emulated which is not shadow DOM . To enable shadow DOM you need to set encapsulation : ViewEncapsulation.Native on each component but that s not really related to your question . Transclusion works mostly the same with or without shadow DOM in Angular 2 . .. . Answer : I find it strange to create dom elements in one component and then simply reproduce them in another - you should be passing your model down the component tree ideally smaller and smaller parts of the model using attributes . In your particular example I don t see two genuinely different parts of the DOM so I would not use nested components at all .", "Question : I have a project where I m using the shadow DOM natively not through a polyfill .

Answer : I disagree with your comments on Java using a BCP api . Whilst I agree about the limitations of Java and ODBC JDBC that doesn t mean there aren t advantages of using a Java BCP api . We have a system with a lot of Java and its not practical or very effective to shell out from Java and run the BCP command-line utility . Running the command-line utility doesn t give very good error reporting and deadlock retries . It also requires the writing of data to a file which is going to increase the number of operations and slow down the whole process . Sometime we can t even write a file as its on a grid which doesn t have a file system and tmp is too small .

Answer : The answer is NO . But why on Earth would you want to move masses of data from Java to the server 1 Java isn t designed for that so it will be very slow 2 native bcp or C+bcp or perl+bcp or any shell command+bcp would scream circles around it and displace it anyway .

An ordinary PROGRAM that connects to the ASE server Client-Server style uses the provided Open Client Library this is native and moves the TDS packets efficiently . The connection is a universally available one inch garden hose . PROGRAMS written in C C++ COBOL Perl and PowerBuilder use this transport . 2 . ODBC and thus JDBC because it is built on top of ODBC is a simple method of connecting to the server using a one millimetre hose . While this is quite adequate for tasks such as using Excel to draw charts directly from ASE tables where the data-transfer speed is not relevant it is quite inadequate for moving data of any substantial volume for normal app access to a data server except where the programmer is ignorant of the fact that 1 is available . . Java does not have 1 and is limited to this 2 transport . 3 . bcp is an utility PROGRAM exists on its own supplied by the vendor that connects to the server much more tightly . It is not a special bit of the client API . There is no lying and cheating involved all constraints are directed by the DBA performing the task . The connection is a two and a half inch fire hose not generally available to the public . It is designed to move large-data volumes at speed . If used on the same host as the server since the hose is not reticulated through the network it moves data even faster . 4 . Much later the vendor made the bcp capability available as a Library API in your terms which can therefore be invoked from any reasonably architected compiler . C C++ COBOL and Perl are such and produce PROGRAMS and therefore provide access to this library directly from your code . The connection is the same two and a half inch fire hose but due to the additional layers it runs at a maximum speed of a two inch fire hose .

Since Java PROGRAMS are currently limited to the one millimetre connection to the ASE server there is no use in providing the bcp API to Java you will merely have a two and a half inch fire hose reticulated through the network with a FLOW of one millimetre it is an absurd enterprise . There is a reason why despite the millions many organisations have poured into Java during its rather long um progression none of them have spent money in providing a firehouse that moves drips and drops . You cannot obtain the speed of a greyhound from a dachshund there is no use giving it racetrack training . You can stop whispering promises in its ear . Second Java cannot handle large source data sets efficiently it was not designed for that . Therefore even if the JDBC strangulation was lifted eg . a native Open Client Library was implemented it still cannot move data as fast as C C++ COBOL Perl PB it will move data at a trickle quarter inch in the one inch hose . Therefore even then it would be absurd to provide the bcp capability to the Java library that would be worthwhile if and when Java which was designed with other priorities in mind is annointed with large-data transfer capability . It may help to move out of your Java Java and nothing but Java mindset and Use the Right Tool PROGRAM for the Job . If you are a Java programmer then at least you need to familiarise yourself with the capability and limitations of your programming language and the libraries available . The original question demonstrates complete ignorance of that hence I had to supply it in my revised post . Programmers who are not limited to Java think about where the large-data source is located minimise data transfers across networks think about what PROGRAMS are already written and that can be used as opposed to writing their own in isolation from the rest of the planet and use them . Finally for understanding even if you did obtain the bcp capability in some Library and implemented it when you place the program in the real world any reasonable DBA will dismiss it due to its trickle speed data transport and use bcp with its fire hose instead . Comment : catless.ncl.ac.uk Risks 26.20.html subj2 http : catless.ncl.ac.uk Risks 26.20.html subj2 Comment : I found this great article on why you shouldn t run shells to get things done . Comment : You re looking for evidence to support your fixed position . The idiot who implemented the reported system does not understand how to set up security on an Unix system . MySQL RUby etc all freeware is wide open to hacking enterprise dbs are not . But let s not get distracted there are millions maybe billions of shell perl scripts running successfully on the planet most secured but some mickey mouse shops are unsecured . Comment : Java can be quite slow particularly when programmers insist on massive object structures which are all built on the heap with 12 bytes of overhead per object and pointers flying everywhere . However for low-level loops Java is not much slower than C++ an interesting exception is some abysmal floating-point functions . There certainly have been native java drivers to Sybase for a long time no need to go through ODBC .", "Question : A long time ago I figured out that bcp is just a little C program that calls the special bit of the sybase client api to do mass data moving into the database . It lies cheats and steals and skips check-constraints all in the name of speed . Great I m all for it . In sybase 12 I noticed that the api was exposed in the C client library but not the java one . I ve been looking but I haven t found anything that says they ve yet implemented it in the sybase 15 java client library . Does anybody know if this is available or not in sybase 15 .. . Answer : If you don t mind your Java program not being portable anymore you can link-to any C library via JNI . That is preferable to having to rewrite your application or to calling a separate task to BCP the data .. . .. .

Comment : So I found where I needed to make that change but now I am getting a new error : GL glx.h : No such file or directory same thing except this time when I changed it to OpenGL glx.h the error still appeared.. . Comment : @jasonaburton : FreeGLUT is not the same thing as GLUT . FreeGLUT implements many of the same functions but it also adds many more that were never in GLUT . I don t know what OSX ships with but it s probably a hacked version of the original GLUT which likely won t support any of the FreeGLUT extensions .", "Question : Some context : I am going through a tutorial http : openglbook.com on using OpenGL . The tutorial requires a couple libraries in order to work . One of those libraries is FreeGLUT . I am on OS X using Lion . I ve downloaded FreeGLUT and followed the instructions http : freeglut.sourceforge.net docs install.php for installation but when I run the make all command I get this error : .. . .. . I ve scoured the internet for a solution and all I ve been able to understand from this is that the compiler is having trouble locating these files and that the path that the compiler is using needs to be changed . EDIT : Okay I ve figured out that it s not the compiler it is that for some reason those files are not there . Going to try figure out why they are not there . Comment : I m not familiar with Mac but you need to install both the OpenGL and GLU development libraries to build FreeGLUT which depends on them . Comment : Using Xcode you can just add a library to a project and OpenGL is a library that can be added so I just assumed those files were installed . Any ideas on how I go about doing that Hehe.. . .. . Answer : That tutorial OpenGLBook.com is based around OpenGL 4.0 core contexts with 3.3 core contexts as an alternative . At best on OS X with Mountain Lion you ll get a 3.2 core context which is similar enough to 3.3 - but unfortunately this is incompatible with GLUT - OS X includes the original GLUT unmodified due to licencing issues which requires many obsolete OpenGL functions that aren t available in 3.2 core contexts . If you want to do this tutorial on OS X 10.6.3 or later without having to deal with many annoying incompatibilities and with future-proof OpenGL I recommend installing a recent version of XQuartz 2.7.2 or later which includes FreeGLUT 2.8.0 to start with . http : xquartz.macosforge.org trac wiki X112.7.2 Comment : Hi I was not able to get a 3.2 context using FreeGlut via XQuartz . I was able to get a 2.1 context with out any issues but I could only get 3.2 via Cocoa . I d love to find out if this can be done .", "Question : I m trying to compile an OpenGL program using Visual Studio 2013 but I get the following error : .. . .. . Error 1 error LNK1104 : cannot open file freeglutd.lib .. . .. . .. . For reference I have FreeGLUT installed and have configured VS to search the correct directories for the include files and library files . Indeed VS recognises the GLUT include files just fine . I ve also added opengl32.lib and freeglut.lib to the Additional Dependencies . Why is VS looking for freeglutd.lib It s definitely not listed in the Additional Dependencies . I can solve the compilation error by renaming libglut.lib to libglutd.lib and removing the former from the dependencies but I m just curious why it s behaving this way . Speaking of Additional Dependencies is adding opengl32.lib actually necessary I can compile my very basic program without it but more than one person has said it s required perhaps for older versions of Visual Studio Comment : Try doing a solution-wide search for libglutd.lib and see what emerges . I suspect that one of your project XML files is slightly corrupted . Comment : @Robert Harvey : I searched the entire solution for libglutd.lib and freeglutd.lib I guess that s what you meant but nothing was found . Edit : I checked the log file as well and the link command doesn t have freeglutd.lib as a library . .. . Answer : Possibly already answered : freeglut error LNK1104 http : stackoverflow.com questions 11954344 freeglut-error-lnk1104 .. . .. . Also two things to check for : .. . .. . Are you building in debug or release-mode The d at the end of freeglutd.lib suggests that it s a library meant for debug builds .. . Try creating a new project from scratch put some basic runnable code in it that uses freeGLUT and see if VS is linking properly . This will also verify if for some reason the project file of the previous project was corrupted as @RobertHarvey suggested or the problem is somewhere else Comment : I looked at that answer before and it didn t help unfortunately . I tried both debug and release-mode . I also did as you suggested and created a new project but no luck . Comment : Hmm interesting . Btw I just so the end of your question - yes opengl is needed as a dependency because freeGLUT uses OpenGL but covers some of its complexity window creation input event-handling initialisation of OpenGL stuff etc . Can you post a screen shot of your project settings linking dependencies headers etc . . OpenGL does not require freeGLUT but I have the feeling that you are writing OpenGL code from somewhere where freeGLUT is used instead of pure OpenGL hence the dependency on freeGLUT . Comment : I just realised I wasn t applying the suggestion from the linked answer properly . I defined those macros after including GL glut.h which is pointless . I can now say the problem is with FREEGLUT LIB PRAGMAS being equal to 1 . More specifically if it is equal to 1 GL freeglut std.h will try to link libglutd.lib if NDEBUG is not defined . So it is meant for debug builds but Release mode doesn t define NDEBUG by default . PS upon inspection of the glut header file opengl32.lib is linked for you if FREEGLUT LIB PRAGMAS is 1 . Comment : Glad it worked out :", "Question : The FreeGLUT API documentation does not include an entry for glutInitContextVersion and when I google for it all I find are a list of questions which don t directly address its usage or effects . Is it documented anywhere .. . Answer : glutInitContextVersion is not part of the official GLUT API which is btw . completely outdated but an unofficial extension added by freeglut . However its usage is quite straight-forwadd as soon as one knows about how OpenGL s context versions work which was defined in the ARB create context https : www.opengl.org registry specs ARB wgl create context.txt familiy of extensions . The function will select which OpenGL version is requested when the context is actually created . Note that this does not require the implementation to return a context with exactly the version you are requesting but it should return one that is compatible to the requested version so that all features of that version are present . There are a few things which seem to be undocuemted about freeglut handling this . From looking into the code for the current stable version 2.8.1 one will see that freeglut implements the following logic : If the implementation cannot fullfill the version constraints but does support the ARB create context extension it will generate some error and no context will be created . However if a version is requested but the implementation does not even support the relevant extensions a legacy GL context is created effectively ignoring the version request completely . This seems a bit inconsistent to me . However as this stuff is not documented and not part of the GLUT spec it is unclear if the behavior will stay the same in the future or not . If you don t need some GLUT-specific features which are basically all relying on deprecated OpenGL anyway you ll might want to look at some more modern alternatives like GLFW http : www.glfw.org . Comment : Thanks that was helpful . I have indeed started looking at GLFW as I didn t realise that FreeGLUT had cross-platform issues .", "Question : I want to create the opengGL context using freeglut . I will first decide the which context to by checking the supporting version using glew and some other parameters . I know for glew to work it needs a opengl context . So I first create a context using glutCreateWindow then check the supported version and then set the version required using the glutInitContextVersion and destroy the previous window using glutDestroyWindow and recreate the new window by using glutCreateWindow . I get this error Freeglut error : ERROR : No display callback registered for window 1 I checked 1 is ID for my previous window which I destroyed . Following is my code .. . .. . I think I need to do this as a openGL context is always required for glew to work . I already tried setting the display function on first window as well though I know I am going to destroy it but that also didn t work . I am setting the current window to new window and then calling the glutMainLoop . So I think this should work .. . .. . According to answer by rhashimoto I tried to put the destroy command at different positions .. . .. . I put the destroy command at begining of reshape callback .. . .. . The I put the destroy command at beginning of display function .. . .. . If I put this at end of Display callback it does not give error but the displayed scene is not correct . Somethings are missing from the scene .. . .. . So is there some specific callback function I need to put this display command I dont think there is any destroy callback I can set . yes there is glutCloseFunc but I think that is meant to be called when window is being destroyed that is when glutDestroyWindow has been called on window .. . Answer : I think you can argue that this is a FreeGLUT bug either in the implementation or the documentation . It looks like glutDestroyWindow needs to be called from a GLUT callback to work properly . glutDestroyWindow mainly puts the window on a list to be destroyed https : github.com dcnieho FreeGLUT blob c59188a9a8d14efbeed7b0d6feacae7b04d7ad69 freeglut freeglut src fg window.c L263 as well as clearing all callbacks https : github.com dcnieho FreeGLUT blob c59188a9a8d14efbeed7b0d6feacae7b04d7ad69 freeglut freeglut src fg structure.c L177 except a destroy callback . This is probably why setting the display function didn t work for you - it was removed when you called glutDestroyWindow . Windows are actually destroyed-at the end of each main loop https : github.com dcnieho FreeGLUT blob c59188a9a8d14efbeed7b0d6feacae7b04d7ad69 freeglut freeglut src fg main.c L466 . So on the first time through the loop your window still exists . The fact that it has no display callback makes GLUT unhappy https : github.com dcnieho FreeGLUT blob c59188a9a8d14efbeed7b0d6feacae7b04d7ad69 freeglut freeglut src fg main.c L410 . The best workaround is probably to arrange to call glutDestroyWindow only via one of the GLUT callbacks . I don t know if this will make the window briefly flash on the screen . My guess is it won t but it might depend on the platform . Comment : I have updated my questions . please see Comment : Weird . Try glutIdleFunc https : www.opengl.org resources libraries glut spec3 node63.html . Comment : My glutIdleFunc is same as my Display function Comment : Not sure what you mean by that . Do you mean that there is no error but some objects aren t drawn If so are you sure that using this extra window is causing the objects not to be drawn And are you sure you are destroying the correct window giving them different title bar names would help distinguish them", "Question : null .. .

Answer : Unlike OpenGL which availability in a compiler toolchain is mandated by the Windows ABI FreeGLUT is an optional 3rd party library that must be installed separately .

Comment : @ChrisProcak : Well the problem you re running into is that Cygwin tries to provide maximum compatibility with Linux . And in Linux you do graphics through an X server . But in Windows there is no X server unless you start the X server that comes with Cygwin but the OpenGL support of that is meager at best . Instead of Cygwin I strongly advise you to use MinGW to compile your project .

Answer : Freeglut is an extended implementation of the SGI GLUT Toolkit and with a few exceptions around obsolete hardware implements the same functions . Unfortunately this includes a number of features that would break in a strictly CORE FORWARD COMPATIBLE implementation . Typically if you request a context WITHOUT specifying a version or profile you will get the best that the combination of driver and GL toolkit can offer which is normally a compatibility profile rather than core profile . Note that the only thing you lose through using a compatibility profile is the supposed checking for deprecated functions . All new core function should work without issue . This problem with freeglut is not restricted to Apple it also manifests under Linux using some Gallium drivers . It is not clear that there is any short-term intent to rectify this so if you need to use CORE FORWARD COMPATIBLE you should probably switch to GLFW or SDL .", "Question : I want to create a window covering my whole desktop screen with displaying colors RGB and then VIBGYOR .

Comment : I am sorry but don t see how this relates to my question . As I have shown - it DOES work with GLFW which runs on top of XQuartz on my system so it does definitely support 3.2 contexts . Comment : I am sorry but don t see how this relates to my question . As I have said - OpenGL 3.2 DOES work with GLFW which runs on top of XQuartz on my system so it does definitely support 3.2 contexts . My only issue is that I would like to use freeglut purely because it s more convenient . But if that s not possible then I will develop using GLFW . But please don t tell me it s impossible to get 3.2 context because I ve already got one . Comment : glfw also has a Cocoa and Carbon port http : sourceforge.net p glfw svn 1617 tree trunk lib are you certain it is running on top of XQuartz", "Question : I am using the following configuration .. . .. .

Another solution is given at http : stackoverflow.com a 13751079 524368 Comment : That did the trick Thanks . Our teachers test program actually initiated the core profile before initializing context 3.2 which for some reason did not work for me . Comment : update It did not work .

What is JFugue trying to download stuff over the network A little debugging revealed it works by downloading .. . .. . Few questions to the people who work on this : - .. . .. . 1 . Why doesn t this code work with MusicXMLParserListener class This class fails with an arbitrary null-pointer exception because it expects Staccato parser to be defined . Why And what is the deal with two different listeners for MusicXML - MusicXMLParserListener J and MusicXMLParserListener R Don t expose broken stuff to consumers please . 2 . I had read that JFugue supports MusicXML and I expected this to work without an issue . Are there examples of JFugue working with MusicXML .. . Answer : The two different parsers you see are a result-of MusicXML capability in JFugue 5.0+ not being fully completed yet which is mentioned on the JFugue download page . These were two implementations contributed by two developers in the open-source community . Based on your issue I have just updated the JFugue distribution : I moved one of the parsers out and renamed the other one simply MusicXmlParser . It turns out that the other parser MusicXmlParser R is the better of the two . Of course no user would have had any idea about that . My apologies for exposing an incomplete capability . For the record Oops something went wrong is not a JFugue error message but attempting to build file was in MusicXmlParser J which is now out of the code . The following code which is from test org.jfugue.musicxml demonstrates the use of MusicXmlParser . Please note that there is no implementation of MusicXmlParserListener for JFugue 5.0 at the moment . I have updated the download page to make this clear . The MusicXML capabilities within JFugue are entirely community-contributed . Comment : I kind of figured whats going on . JFugue tries to perform a schema validation and downloads the DTD specification from a high-load site . It works half the time because JFugue assumes network IO and that breaks .

Answer : In your first example .. . .. . You are trying to pass a Java expression as a string . However the string itself is not evaluated as a Java expression . Instead JFugue tries to parse scaleNotesC 0 itself as a music string which it is not so you hear no music . If you remove the quotes Java will evaluate scaleNotesC 0 to 60 and JFugue will successfully parse 60 as a Middle-C and play it . The version of JFugue you are currently using does not have a play method that takes a list of strings as a parameter an upcoming release will have this capability .

The code used is : .. . .. . This makes the A note to be played for 6 seconds . In this case i can just divide by 2 and get the wanted result but i am not sure if this is the correct approach . The second problem is when using the symbol @milliseconds which indicates the time in milliseconds when the following tokens should be played . For some reason i can t make the next note to be played after the milliseconds i have declared . In the following example the B note is played at after 34sec instead of 2sec . player.play V0 I Flute A @2000 B .. . .. . Any help would be appreciated . .. . Answer : It seems that you re asking for a custom note duration measured in seconds . The duration you provide for notes in JFugue is measured in beats . To figure out how a long a note will last in seconds you need to multiply the beats by the tempo which is measured in beats per minute or bpm then do some unit conversions on minutes to seconds . The default tempo is 120 bpm . You can change the duration with the T directive in JFugue like T120 or T60 - T60 will have the same effect as dividing the duration in half . I recommend using JFugue 5 if you re not already doing so the management of timing in JFugue 5 is much improved over JFugue 4 . In particular JFugue 5 measures the value given to @ in beats not milliseconds . Disclosure : I m the author of JFugue", "Question : I have a couple of questions concerning JFugue 5 the beta version . From The complete guide to JFugue it is mentioned that depending on the Key Signature in the pattern JFugue interprets the note value . As an example in the case of an F-major key B would be automatically translated to B-flat unless we write Bn instead . The question is that if we are dealing with an F major key and write Bb how would JFugue interpret it As Bbb or as a Bb note My second question is about transposing Keys in JFugue . What is the fastest way of doing so Thank you for your help .. . Best Regards .. . Hussein Hammoud . Comment : These are both excellent questions thank you I ll do my best to answer them but unfortunately I can t do it today . Comment : Oh And I have another question JFugue 5 is giving me an error when I play a pattern containing a numerical value of a note example : C5 corresponds to 60 . That is not the case in JFugue4 . Any suggestions are appreciated . Comment : For that last one use 60 without the brackets . JFugue 5 does away with brackets except in cases where the stuff inside the bracket is a string to look up in a dictionary e.g . T Allegro or I Piano . Numbers are just numbers and do not need brackets in JFugue 5 . .. .

And its output note that MIDI Note 70 is Bb and MIDI Note 71 is B : .. . .. . Answer to the second part of your question : I m not sure there s a decent answer right now . But you have inspired me to write a transpose method on the Pattern class . Thank you Comment : Thank you for your answers This was really helpful . I am currently trying to write the transpose method and I will send it to you if it ends up working without any bugs . I appreciate your response : D Best Regards Hussein .", "Question : Say I have a player who is currently playing a pattern and at a certain point I want to set the next pattern that it should play without producing a small pause when it switches between the two . It is similar to Android s mediaplayer class where you can have 2 mediaplayer which each is setNext to the other . With the use of setOnCompletion you can alternate between the two without hearing a small pause or gap . I want to achieve that in jFugue . Thanks .. . Answer : You will want to use JFugue 5 for this as it has improvements over earlier versions of JFugue for playing consecutive patterns . Specifically you ll want to use the new RealtimePlayer . You can send the RealtimePlayer new patterns or music strings whenever you wish like this : Comment : Thank you so much for your answer and for developing jFugue I tried the code that you suggested when I ran my program it didnt play anything . No exception was thrown too . What seems to be the problem On the other hand I have two other questions regarding jfugue : 1- Is it possible to input different soundfonts for different instruments i.e . I have a player that is playing multiple instruments I want to input a different soundfont for each instrument . 2- I want to implement my project as an Android App I am trying to setup kshoji s jFugue for Android . Have you ever tested that project Comment : You re welcome 2 . 0 Hard to diagnose the problem from a distance .

Comment : @DavidePastore I like that you solved the problem . Note it seems you like to play with eclipse but be aware that eclipse itself if a good tool but not all the problems you could solve with it .

Can this be done with CQEngine or would I need to flatten the objects .. . Answer : Yes you just need to define a CQEngine attribute which will return the values from the nested objects you want to search . For example this attribute will retrieve the names of each Product which is contained in the Orders which were placed by a particular User . You could optionally add an index on this attribute to accelerate queries on it . Here s an example which sets up an IndexedCollection of Users where each user has a number of Orders and each order has a number of Products . The products are snacks you might find at a cinema .

I m not an expert on lambdas so I ll just answer regarding the CQEngine part : You need to use rows.retrieve to make CQEngine execute a query . Above you re actually bypassing the query-engine and its indexes and accessing the collection directly . There s a bit of discussion on the CQEngine site about how to perform queries to get a ResultSet .

Is that what you want", "Question : I m considering CQEngine https : code.google.com p cqengine for a project where I need to handle lots of real-time events and execute some queries from time to time . It works well for returning the results but I noticed that the larger the collection gets the slower it becomes to add or remove elements to from it . I have a few simple indexes added on the collection so I m assuming the delay is because on each event added removed the indexes are updated . I also get an OutOfMemoryError on large numbers of events from the indexes increasing along with the collection I think . So my question is what is the indexing penalty in CQEngine for a fast changing collection elements often added and removed from the collection .. . Answer : If you have a lot of unique values in attributes that you index you would probably benefit from IndexQuantization http : code.google.com p cqengine wiki IndexQuantization discussed on the site . This is a way to tune the tradeoff between memory usage and retrieval speed . But it s especially useful to reduce the size of indexes in memory if you have a large number of unique values . FYI you can also ask questions in the CQEngine discussion forum https : groups.google.com forum forum cqengine-discuss . Hope that helps Comment : Thank you for taking the time to respond . Don t know if the IndexQuantization would help since the values I m indexing although unique they are not in sequence . Will give It a try though . Regarding the addition removal of elements to the collection I noticed that adding elements is slower if I have indexes on the collection than without indexes . Is that because on each add remove the index gets reorganized Comment : It might depend on which type of index you are talking about as you didn t mention . They all use different data-structures . But in general no indexes are not reorganized as each object is added . The HashIndex is basically a ConcurrentHashMap AttributeType Set ObjectType . So adding objects will either add new entries a new Set to the CHM if objects with the attribute value are already stored or to the existing Set if already stored . Comment : If your values aren t in sequence you could write your own implementation of the Quantizer interface . For example a simple implementation would mod the attribute value to the number of entries in the index you want e.g . value desired index size . Comment : Also if the values you are indexing uniquely identify an object that is primary key-type attributes then you can also try the UniqueIndex http : cqengine.googlecode.com svn cqengine javadoc apidocs com googlecode cqengine index unique UniqueIndex.html .

Answer : You can safely remove that dependency if you are not using it . I m the author of CQEngine . The situation of which dependencies can be safely be removed should indeed be documented better . I ll try to do that in future . Comment : Ok thanks And good job with your project it is really awesome", "Question : null .. . Answer : I have an issue in using CQEngine . My requirement is to create Attributes Dynamically . And use them while querying . I need to have sql-like function which is matchesRegex as well as equal function . Problem : if i Keep the Attribute Data Type as Attribute ClassDataType Comparable Generic purpose i cannot use it for Regex query as it needs something that extends CharSequence and if i make it Attribute ClassType extends Comparable can use it for regex by typecasting it to Attribute ClassType String then equal method doesn t accept Attribute . What would be the solution for this.. . Will appreciate any response .", "Question : I have a table from which I extract 8 columns said columns will be properties of a pojo say MyPojo .

From a performance point of view which one is better Comment : The one which runs faster on your machine for your dataset . The best way to find that out is to test it . .. . Answer : The best way to decide these things is to model it . What are the access patterns in your application If this is would be a one-off request : have the database do the filtering . If you expect to get many such identical requests : have the database do the filtering and consider caching results in the application . If you expect to get a variety of queries on the same dataset consider caching the unfiltered dataset into the application tier and querying it with CQEngine . There is no rule of thumb such as always have the database do the work . If your application operates at any kind of scale you will not want every request to hit the database . You need to scale out your application tier . On the other hand you should not over-engineer . The answer depends on the traffic volume and data-access patterns that you expect .", "Question : I use cqengine https : github.com npgall cqengine for collection indexation : .. . .. . This code isn t compiled because : .. . .. . Probably it s a lack of library design : LocalDate implements ChronoLocalDate that extends Comparable ChronoLocalDate it means that it s necessary to use wildcard bounds in generic method declaration . I guess creating of LocalDate wrapper that implements Comparable is a workaround in this case . Perhaps there are some other solutions of this problem .. . Answer : I think creating new classes like a wrapper is to much overhead for fixing a generic signature error . I d create a delegation method like .. . .. . Actually the problem lies in the declaration A extends Comparable A which should be A extends Comparable super A however fixing it here wouldn t help as this pattern is spread throughout the API and allowing such a return-type here would just raise errors at the next API usage . But since as far as I understood Attribute only produces A s but doesn t consume them we can relax the signature here and accept an Attribute extends A following the PECS http : stackoverflow.com q 2723397 2711488 pattern .

But not found the solution . Sorry for post again because I have not earn enough reputation to comment . I just run Grafika sample application Show + capture camera on Samsung Note4 . It will crash after a while maybe 2-3 minutes . I also tried to change attribList as Endre B rcs k mentioned but not work . Hope someone can help . My stack-trace show below :", "Question : I am trying to record the video using GLSurfaceView and audio from the AudioRecord . In MediaMuxer I am sending both audio and video data when onFrameAvailable called . I set the camera preview size of 1280 720 and preview on the full screen . I am having problem to crop the frame to 600 600 . Can anybody help me to crop the video frame before encoding to MediaCodec and MediaMuxer . I am taking help from the Grafika android demo code .. . Answer : You need to solve to problems : .. . .. . 1 . Record video with 600 600 : Use video codec with specified width height . This is easy to do but it could be that not all phones have hardware codecs that will supports you custom resolution . 2 . Scale video in the way it will look not stretched because you have changed w h ratio . Use view matrix passed to OpenGL shader with needed scale . Comment : Can you please elloborate the second point . Give an example for the Use view matrix passed to OpenGL shader", "Question : I am using MediaCodec to play 1080p@60fps video . This is on freescale SabreSD platform with Android Lollipop 5.1 . Initially because of BufferQueue Synchronous Mode the FPS was way below 60.I could now manage to play at 70FPS by changing the BufferQueue to Asynchronous as in JB . Now the next challenge I am facing is the video lags and FPS drops drastically to 40 when I start interacting with the screen pulling down notification bar pressing volume button etc . So I ran rafika MultiSurfaceActivity and Record GL I can see all the test play smoothly when no screen is touched or disturbed but as soon as I start scrolling the notification bar from top and continue that for long time the fps gets reduced to 35-40FPS . I have confirmed the same test on Kitkat 4.4.2 and JB 4.2.2 and they seems to work fine . Same behaviour when playing MP4 from Gallery . The video gets stuck and lags a lot when we start playing with Notification bar .. . .. . Can anyone explain what has change from Kitkat to Lollipop which can cause this issue VSync Triple Buffering . .. . Answer : Regurgitating a bit from the Grafika issue tracker https : github.com google grafika issues 46 : .. . .. . The bouncing ball is software-rendered so anything that soaks up CPU time is going to make it slow down . On devices with medium-grade CPUs and big displays e.g . Nexus 10 it never gets close to 60fps . So a slowdown while you are playing with the nav bar doesn t surprise me but if it continues to be slow even after you stop playing with the nav bar then that s a little weird . Video playback should be less affected as that does less with the CPU . Investigation into such problems usually begins by using systrace http : developer.android.com tools debugging systrace.html to capture traces in good and bad states and comparing the two . The key point of BufferQueue async mode is to allow frames to drop if the consumer can t keep up with the producer . It s primarily meant for SurfaceTexture where producer and consumer are in the same app potentially on the same thread so having the producer stall waiting for the consumer could cause the program to hang . I m not sure what you mean by needing it to exceed 60fps but I would guess you re throwing frames at the display faster than it can render them.. . so you re not really increasing the frame-rate you re just using the BufferQueue to drop the frames instead of using Choreographer to decide when you need to drop them yourself . In any event I left Google back in June 2014 well before Lollipop was completed . If something works correctly on KitKat but weirdly on Lollipop I m afraid I can t provide much insight . If you can reproduce the behavior easily it might be worth capturing a video that demonstrates the problem point a second smart phone at the device exhibiting the problem so they can see how you manipulate the device and filing a bug on http : b.android.com . .. . .. . Some traces uploaded by the OP : .. . .. . https : www.dropbox.com s luwovq7ohozccdy Lollipop bad.zip .. . https : www.dropbox.com s zkv0aqw0shecpw2 lollipop good.zip .. . https : www.dropbox.com s g7qe01xvmfyvpak kitkat.zip .. . .. . Looking at the kitkat trace something weird is going on in SurfaceFlinger . The main thread is sitting in postFrameBuffer for a very long time 23-32ms . It eventually wakes up and the CPU row suggests it was waiting on activity from a galcore daemon which I m not familiar with seems particular to Vivante GPU . The lollipop traces only show the CPU rows as-if the capture were done without the necessary tags . I don t believe the systrace capture command changed significantly between kitkat and lollipop so I m puzzled as to why the user-space-initiated logging would vanish but the kernel thread scheduling stuff would remain . Make sure you have sched gfx view specified . .. . .. . The newer lollipop traces only have about a second of good data . When you see Did Not Finish it means a start record had no matching end record . You can increase the systrace logging buffer size with the -b flag . I think there s enough there though . Looking at the system bin surfaceflinger row you can see that in the good trace postFrameBuffer usually finishes in about 16ms but it s still waiting on galcore . Zoom in on 388ms use WASD keys . At 388.196ms on the CPU 2 row you can see galcore do something . Right after it completes the thin line at the top of the surfaceflinger row changes from light grey sleeping to green running . At 388.548ms again on CPU 2 galcore runs again and right after that on the surfaceflinger row you see queueBuffer start to execute . The bad trace looks identical . For example you can see two galcore executions at 101.146ms and 101.666ms with what appear to be similar effects on the surfaceflinger row . The key difference is the time spent in postFrameBuffer which is around 16ms for good and around 30ms for bad . So this doesn t appear to be a behavioral shift rather things are taking longer and deadlines are being missed . As far as I can tell SurfaceFlinger is being held up by galcore daemon . This is true in both good and bad cases . To see what the timing should look like you can run systrace on a Nexus device or compare to traces from other devices e.g . the one in this case study http : www.curious-creature.com docs android-performance-case-study-1.html or this SO question http : stackoverflow.com questions 18704702 . If you zoom in you can see doComposition executing in a few milliseconds and postFrameBuffer finishing in a few tenths of a millisecond . Summing up : you don t have good and bad you have bad and worse . : - I don t know what galcore is but you ll likely need to have a conversation with the GPU OEM . Comment : Yes I used all the above tags while capturing in kitkat and lollipop and I followed community.freescale.com thread 380812 https : community.freescale.com thread 380812 to enable all the tracing in kernel but missed CONFIG SCHED TRACER I will enable that and let you know if the systrace output changes Comment : If it were a kernel config issue I d expect sched to be missing and all the user-space stuff to be there . Your trace is the other way around like the ftrace code is working but ignoring the user-space stuff . Comment : Hi @fadden Updated systrace dumps are dropbox.com s hnebmkkghp534iy lp bad.zip dl 0 https : www.dropbox.com s hnebmkkghp534iy lp bad.zip dl 0 and dropbox.com s zr3dwibj4yb89h7 lp good.zip dl 0 https : www.dropbox.com s zr3dwibj4yb89h7 lp good.zip dl 0 . The problem was with debugfs permission which prevented the other processes to get logged in systrace dump Comment : Answer updated . Comment : Yes I see galcore daemon is taking more time compared to the kitkat 4.4.2 version on same hardware . Galcore is Vivanta s GPU Module I will pursue this with freescale team and update you asap . Thanks for you quick response really appreciate your help :", "Question : We know that we will get a lager field of preview at the same distance when camera preview ratio set to 4 : 3 instead of 16 : 9 the detail is as follows : .. . .. . Android Camera API - Weird zoom effect http : stackoverflow.com questions 20664628 android-camera-api-weird-zoom-effect .. . .. . But I encountered a problem when I worked with android-camera preview with opengl that is the second way mentioned below . There are 2 ways of implementing camera preview : .. . .. . 1 . Traditional way without opengl just use Camera.setPreviewTexture SurfaceTexture texture or Camera.setPreviewDisplay SurfaceHolder holder .. . 2 . The way of ContinuousCaptureActivity using opengl we render the preview image with API swapBuffers . The first way is OK I will find that preview field become larger if preview ratio changed from 16 : 9 to 4 : 3 . However The second way is not OK in some android phones the preview field stay the same when preview ratio changed and the preview field is smaller than the first way at the ratio 4 : 3 . I insist that this is an error I want to resolve this problem very much Who can give me some advices Comment : @fadden Dear please take a look at this I expect your comments . Comment : No there can be no guarantee that the FOV of wide picture will be a crop of 4 : 3 picture even if this is common behavior on many devices . This is handled by HAL so Camera2 API may be different from Camera API on the same device . Comment : Continuous capture is just calling setPreviewTexture as in 1 . The method of rendering the preview shouldn t have any effect on the output from the camera -- Camera is just sending each frame to a Surface . Whether the Surface is attached to a SurfaceView or SurfaceTexture doesn t matter . It ll look different if the Surface is displayed differently i.e . the aspect-ratio is off or the layout puts the Surface partly off-screen but the resolution and aspect-ratio are chosen by Camera and shouldn t be affected by how the Surface is used . Comment : @fadden But 2 works OK on some devices such as nexus 6 this is true . So I assume there may be some other reasons . Comment : @fadden Take a look at the answer I have found the reason .. . Answer : After a struggle I finally found out the exact reason it is the API Camera.Parameters.setRecordingHint true .. . .. . When I removed this clause in my source code the field of preview became normal . In one word the API Camera.Parameters.setRecordingHint true is a bug in some android devices . .. . .. . For some devices if preview ratio is set to 4 : 3 use API Camera.Parameters.setPreviewSize int int calling API setRecordingHint true will cause the field of camera preview to be smaller . Comment : Please clarify . Does setRecordingHint cause the frame size to change Or the the aspect-ratio to change Or zoom Comment : @AlexCohn For some devices if preview ratio set to 4 : 3 calling API setRecordingHint true will cause the field of camera preview to become smaller . Comment : Thanks nice to know . But seriously this is not a bug by any definition I can imagine . There is no requirement that camera focus distance be constant when changing the parameters : setRecordingHint autoFocus scene or other ." ] }

The requirement is that they need to ship items all over Europe and North America . So it needs to be multi-currency multi-language . Also there is a subscription model so the credit-card needs to be stored and periodically charged . Further they need it to integrate with QuickBooks which is they accounting software . Also the software will have web iOS and Android versions . So for the storing credit-card part I do not want to store it within our infrastructure because of PCI DSS issues . Instead I would prefer having something like paypal vault . However I cannot use paypal because their mobile SDK does not support recurring payments subscription model . With paypal ruled out I have been looking at X-Cart for the shopping interface and couple of other payment companies akin to authorize.net for the payment integration . However I am getting confused with X-Cart . It talks a lot about PCI compliance and stuff so I am wondering whether it is a full package not just shopping cart I read tons of documentation but I still cannot wrap my head around it . My Questions : .. . .. . If I use X-Cart do I need any additional payment integration system like Paypal Since X-Cart is a downloadable software what PSI implications does hosting it in our own server have How will I handle iOS and Android versions does X-Cart do anything for those platforms I was surprised to see X-Cart was a SO tag . So I decided to reach out to anyone with prior X-Cart experience to help me get some directions . Thank you Comment : Off topic for S.O .. . Answer : All the latest versions of X-Cart do not touch credit-card information at any point . So it is out of PCI-DSS scope and can be hosted on any server you like as long as it meets the system requirements . And to process credit cards you can use any of the integrated payment gateways . X-Cart does not charge any transaction fees so the only fees you will be paying will be to the gateway itself . And if the gateway you would like to use is not integrated yet you can add it yourself since the platform is fully open code . As for subscriptions X-Cart offers a stand-alone PA-DSS certified X-Payments software that utilizes tokenization technology supported by certain payment methods including PayPal Pro to save credit-card information for further use in a PCI-compliant manner . The actual credit-card number is saved by the payment-gateway itself . And X-Payments uses the token to perform additional charges . The token cannot be used with any other gateway or X-Payments installation so even if it gets stolen there won t be any harm . You can read more about it in this blog post http : blog.x-cart.com pci-compliant-credit-card-saving-in-x-cart-and-x-payments.html .

For example is it possible to use both USD price and AUD price for a single product or different products in a single web-site using X-Cart . .. . Answer : If you use X-Cart GoldPlus or Platinum you may SHOW PRICES in several currencies . It s possible due to multicurrency module which is built-in to the versions above and is a separate paid add-on for X-Cart Gold : http : www.x-cart.com extensions modules multicurrency.html It s actually for customer s convenience - he will no longer need to recalculate the cost into his local currency . However as I understand you want not only to SHOW but also to PROCESS orders in different currencies . By default it s not possible but you may want to consider such a custom modification from 549 : http : mods.x-cart.com Advanced-Multi-Currency-Support.html", "Question : I m currently using X-Cart and have some employees each has an X-Cart administration account . I also develop some custom PHP webpages not X-Cart modules which require my employees to login before they can access those webpages . I want my employees to use their existing X-Cart accounts to login . For example whenever my employees access custom webpages if they re already logged in to X-Cart they should be fine . If not they should be redirected to X-Cart s admin login page . My question is : How can my PHP scripts check if users are already logged in to X-Cart I tried to include auth.php but I got the error message Can not initiate application Please check configuration . .. . .. . Thanks a lot .. . Answer : Creating secure admin pages is pretty simple : .. . .. . 1 . create new page in ROOT admin my new app.php .. . 2 . start your code with : .. . .. . My new App is secure .. . require . auth.php .. . require xcart dir . include security.php .. . .. . Put your App code in here.. . .. . .. . .. . You may and you should end with assigning main template as : .. . my main my new app .. . location array New App admin my new app.php .. . .. . .. . But then you need to go and edit YOUR SKIN single home.tpl and add this : .. . .. . elseif main eq my new app .. . include file admin my new app.tpl .. . .. . and you need to create your template file : admin my new app.tpl .. . .. . .. . .. . And that s it . If you are not an admin you will get redirected to Login page administration area . There is one important note here : You can not use post variables in your app without a real form on page . You have to create a form than xcart will create a hidden input field formid and it will have some hashed value such as : 20b8e92504d1908bb1e3a264b9169f1e . Once you have it you can use AJAX and post variables each time including formid and its value . The reason I am telling you this is strange message you get : Can not initiate application Please check configuration . It does not come from x-Cart my guess is : your app tries to post but gets no response missing formid .", "Question : I updated my X-Cart from 4.4.2 to 4.5 .

Here is my website : http : www.farlin-cambodia.com home.php cat 591 .. . .. . How can I fix it .. . Answer : The store you re referring to is of version 4.1.6 that s an old version where there were no adding to cart without redirect with ajax . The behaviour in question is still there thus the feature is added as a custom mode . If JS is enabled in the browser and if the store considers that it s enabled the JS script is supposed to send some data to script minicart content.php and the php script is to process the received data further . However it doesn t happen and there are no JS errors which makes me believe that the problem is in the code of minicart content.php with this file is very likely being modified too . If JS is disabled in the browser and if you click the corresponding button in the store in the pink side menu block - If Javascript is disabled in your browser click here this custom scenario is not applied so the store uses the default functionality which allows to add the products to cart with out problems . Thus the possible solution is : .. . .. . roll back the custom changes you implemented and use default functionality adding products to cart with a redirect to cart page or .. . check the minicart content.php script and find out why it doesn t want to properly process the data sent by JS script .. . .. .

There will be some sophistication in the sense that they would need to support multiple currencies multiple-languages delivery methods subscription models et al . However they are not a market place so they do not really care about multiple vendors or multiple store fronts . Since the site is in PHP I looked at a few like x-cart opencart magisto community edition and prestoshop . The dilemma I have is that the current site management is very particular about design and most of these shopping cart implementations seem tough to me to customize to the level they would want . The alternative is to write a custom cart which is a waste of time effort since we are reinventing the wheel which has already been reinvented a gazillion times . I want to leverage what the open-source community has to give . I feel that the middle path is there is a good package available ONLY as a class module backend - without the front end UI so that I can start using it and building it how I want . How does the PHP community approach this problem . From a solution implementation perspective is it better to build one from scratch I am not sure if anything like that exists though . I would appreciate anyone who can point me to any online resources that will help me in my quest . Thank you . Comment : Question in-between opinion based and a quest for an off-site resource . I fear once again you would not find a solution here . There is really too less chances that you would find someone having experience in all the e-commerce framework you throw in the tags so everyone is as usual going to call for his her favourite or most worked with framework even when they are not the one that should do the work afterwards . So my best advise is : install some of them play with them do yourself your own mind on them and choose based on your own opinion . Comment : I ve been developing open cart modules since over 1 year and I don t recommend it to you the next few sentences are opinion based once you hack the core manually or through extensions every thing will go wrong and you will feel that you are opening the HELL GATE there is no code documentation there is no DB schema documentation you will suffer to understand how things work there so my advice to you is to check it s features if you like it then use it as is if you think that there is a minor possibility that you will edit the core then search for sth else Comment : @AbdoAdel : a very genuinely frank and honest opinion . Thanks .. . Answer : If you cannot find any resources to build from you will need to create this from scratch but this is sometimes the best solution as it will be to the project specification . But my best advice is to look how other cart systems are built and expand and implement functionality like you said don t reinvent the wheel . When completed its always a good idea to upload the project on platforms such as github.com so other people in the same situation can use your code .", "Question : I want to build a custom Settings page on the back-end of X-Cart . I ve been scanning the files and so far I was only able to learn how to add my link-to the admin menu page and I was also able to build the page and assign contents using smarty . The only thing that is missing now in my custom page is the X-Cart s admin header and footer sections all I see is the text outputted using smarty with plain white background only . Here is what I did to create the admin menu link and the page : .. . .. . 1 I created a sample settings.php on the folder : root admin with the following contents : .. . .. . 2 Then I created the sample settings.tpl on the folder : root skin customs skin admin main with the following contents : .. . .. . 3 Then I assigned my new file in the root skin customs skin singe home.tpl just before the else : .. . .. . 4 Then to add the menu item to the Content tab in the X-Cart admin menu I added the following code to the file : root skin customs skin singe menu box.tpl .. . .. .

Answer : If you own a license the distributional package can be downloaded in the File Area of the corresponding HelpDesk account https : secure.x-cart.com . You may also request the package of older versions contacting X-Cart support http : www.x-cart.com contact-us.html . PS : Normally the packages of older versions are requested when the store is being upgraded . If you re upgrading the store of indeed you may want to consider X-Cart 5 - a new generation platform where the upgrades are done in a couple of clicks . Please check it out : http : blog.x-cart.com x-cart-5-downloadable-released.html", "Question : null .. . Answer : I have installed and configured WordPress in X-Cart module for an X-Cart 4.6.4 Gold site . When I enable the module from the X-Cart admin the x-cart front-end crashes with an Error establishing a database-connection . Cannot use object of type W3 Config as array in home username public html include func func.db.php on line 517 message in a blank page . The X-Cart back-end works ok and when I disable the module x-cart front-end works again . Also both WordPress front-end and admin work ok when I enter directly in the WordPress site . The WP site is located in the X-Cart root . I found a solution which I am not sure if it is the perfect but temporarily it works . I tried to trace the code with a debugger in my local dev . server and I found out that in wp-includes ms-settings.php WP script file close to line 57 the code searches for the current blog by querying the WP database via the input path in the browser . This is stored in the current blog variable via the snippet : .. . .. . The current blog variable was set to false thus leading to further empty object regarding the found current WP site and exiting the procedure displaying the Error establishing a database-connection message . From what I noticed the path variable was set to the x-cart root dir relative-path eg if xcart is installed in xcart root dir and the WP blog in xcart blog dir then the path variable was set to xcart leaving out the blog path part thus not finding the blog . On the other hand the current site- path value contains the path to the blog xcart blog so I replaced the above line comment : REPLACED LINE with the one below : .. . .. . Also I did the following things : - I removed any mod-rewrite rules in the .htaccess file of the WordPress root directory because they broke the initial redirection - I tried to remove my code tweak posted in this thread but then the site displayed the database-connection error so I retrieved it back . - I deactivated the W3 Total Cache plugin in WordPress because it kept breaking the site . The strange thing is that I needed to keep my code tweak as well . Anyway the integration worked fine . My question is if my above approach regarding the code modification is correct since I actually modified the original WordPress code which is hardly possible to have a bug in this spot . Comment : What does line 517 say Comment : @Aibrean : line 517 is in bold snippet : if stristr query select false isset config General use old products lng config General use old products lng Y query func transform lng query ext query xcart products lng query func transform lng query base query xcart products sql tbl products lng current Comment : Please put this in your original question and format within code . See the help for how to format code . Comment : Sorry for the delayed replay but I found a questionable solution related to code modification to another part of the code . I have edited my initial question adding this solution .", "Question : So what I need is to somehow save the x-cart cart and basically save this cart not in cookies but in server-side session but databases so that if a client has filled the checkout form in but never checkedout to then email the user saying something like Have you forgotten to pay or something . I hope you get what I mean . .. . Answer : Take a look at this . abandoned cart reminder module for xcart http : www.x-cart.com extensions modules abandoned-cart-reminder.html .. . .. . Its not free but like any other xcart module you wont find them for free xD" ] }

Answer : Depending on your scenario it may be worth looking at utilising signatures or similar allowing direct uploads to Amazon S3 TransloadIT for image-processing or similar services . Our first decision with this concept was that as we are using GraphQL we wanted to avoid multipart form uploads via GraphQL which in turn would need to transfer to our Loopback services behind it . Additionally we wanted to keep these servers efficient without potentially tying up resources with large uploads and associated file validation and processing . Your workflow might look something like this : .. . .. . 1 . Create database record .. . 2 . Return record ID and file-upload signature data includes S3 bucket or TransloadIT endpoint plus any auth tokens .. . 3 . Client uploads to endpoint .. . .. . For cases where doing things like banner or avatar uploads step 1 already exists so we skip that step . Additionally you can then add SNS or SQS notifications to your S3 buckets to confirm in your database that the relevant object now has a file attached - effectively Step 4 . This is a multi-step process but can work well removing the need to handle file uploads within your core API . So far this is working well from our initial implementation early days in this project for things like user avatars and attaching PDFs to a record .

Answer : I m currently working with the loopback-component-passport system for third party enterprise authentication . I ve been using the loopback-example-passport project on github as my template . I m having a hard time seeing where passport is being invoked to actually do the work of authenticating with the data that I ve provided in providers.json . We are building out our application in the Ionic framework so this will be commonly used from the android ios platforms . We do not want to manage their email and password for authentication we simply want to forward them to the enterprise login page to authenticate we receive a token request additional data about the user and create that user in our Mongodb . .. . .. . I setup up a basic express server in node for testing passport and I verified the openIDC strategy I m using is working . In this testing process passport is clearly called in app.get login passport.authenticate as a callback function . How is this process handled when using strongloop and passport What callback function would be used in the routing for app.get login i.e . When is the passport component not passportConfigurator being called initialized to authenticate or where is that happening if not in server.js I am quite certain this is a user error as I m new to all of this but any additional help or resources on how to use loopback-component-passport for third party enterprises openidc authentication would be helpful .

Comment : Since you say you are running selenium tests and looking for code-coverage am guessing your intent here is functional code-coverage of your application . In that case have you ensured that your application has been instrumented using jacoco You would need to instrument your application code have it deployed run your selenium based functional tests against the instrumented app and then later pull the report from the instrumented app . I dont think its going to be appearing in your selenium tests side Comment : thats the idea I thought from what I had read that the instrumented code would be supplied to cargo plugin .

Answer : Short answer : not possible at the time of writing using merely Maven and Jacoco . from official jacoco github page https : github.com jacoco jacoco wiki MavenMultiModule : .. . .. . The current JaCoCo Maven goals work on single modules only : Tests are executed within the module and contribute coverage only to code within the same module . Coverage reports are created for each module separately . There is no built-in support for cross-module coverage or combined reports for multiple modules . Hence your requirements cannot be met merely using Maven and Jacoco . You can however use a common approach in enterprise settings : Sonarqube which will process the generated jacoco files i.e . jacoco.exec and aggregate reporting and governance via its Jacoco integration provided out-of-the-box on its latest versions .

UPDATE : I was missing this bit in the maven-failsafe-plugin plugin : .. . .. . After having added it as in : .. . .. . the integration tests report shows the integration tests . The final full configuration is : .. . Answer : You misunderstood the pattern for the include tag of maven-failsafe-plugin . The pattern is used for the package name of the classes within the test classpath see also https : maven.apache.org surefire maven-failsafe-plugin examples inclusion-exclusion.html . The build-helper-maven-plugin includes all classes in src it java to the test classpath . Then the pattern of include tag in both test plugins surefire failsafe filters the classes within this test classpath . These filtered classes are executed by the test plugins . So the workflow is .. . .. . 1 . Build-Helper-Plugin extends the set of the test classes that have to be compiled and executed . Therefore the source directive is used . The path location defined in this source directive is related to the Maven project path . 2 . Compiler Plugin compiles the java classes . 3 . Jacoco-Plugin should measure the coverage in the production classes with unit tests . Therefore the normal agent has to be prepared before the tests are executed . You can specify which production code should be included or excluded in the coverage measurment include exclude directive . The pattern in these directives are package-based shlashes are used instead of dots . 4 . Surefire-Plugin executes the tests whose full-qualified class name match the pattern of the include directive . The pattern uses slashes instead of dots . 5 . Now the Jacoco-Plugin should measure the coverage in the production classes with integration tests . Therefore the integration agent has to be prepared before the tests are executed . And again you can specify which production code should be included or excluded in the coverage measurment include exclude directive . The pattern in these directives are package-based shlashes are used instead of dots . 6 . The same for the Failsafe-Plugin . It executes the tests whose full-qualified class name match the pattern of the include directive . The pattern uses slashes instead of dots . Comment : I understand I must use a path pattern and not a package pattern . Is that right Are you saying all classes are mix together in the very same directory There is no way then to differentiate them with a sub directory name Only a class name suffix like IT can help here Comment : No the other way around . You have to use a package pattern . After compiling all compiled classes from src it java and src test java are under target test-classes the test-classpath . Then the surefire failsafe plugin executes the classes described by the pattern in the include tag . Therefore your approach using a class name suffix will help . BTW check the default suffix of the failsafe plugin maven.apache.org surefire maven-failsafe-plugin http : maven.apache.org surefire maven-failsafe-plugin integration-test-mojo.html includes to reduce the configuration . Comment : I m still confused as the doc shows path like includes . The slash means path like . The dot means package like . I tried this config : configuration destFile project.build.directory coverage-reports jacoco-it.exec destFile propertyName failsafeArgLine propertyName includes include .it . include includes configuration and include it include but these two configs didn t include anything . I have my integration tests in an it folder . You d know how to express that as an include Comment : For example you have two classes named com.example.integrationtest.ATest and com.example.unittest.BTest . ATest.java is located in src it java means failsafe should execute it and BTest.java is located under src test java means surefire should execute it . Then the include pattern for failsafe is include integration include and the pattern for surefire is include unittest include . It is a pattern for package but they use slashes instead of dots . Comment : In my last comment it should mean it s not a good approach . The reason is that you can have trouble with your structure if you tests package-protected classes . I will prefer the suffix way .", "Question : null .. . Answer : We have several different faults with our jacoco.exec file see the Error types below .

I am facing the following issue with publish-subscribe : .. . .. . My main page has two section navigation and mainContainer both loaded as modules external html templates and js files and I am setting the name of the modules with observable so it can be replaced dynamically . In the mainContainer there is a tree and if the user clicks on any node of the tree then two things should happen . 1 . The entire mainContainer module needs to be replaced with a different module called detail in the same div tag . 2 . Based on the node in the tree that the user has clicked in the mainContainer I need to pass the value as a parameter to this detail module . I figured I can achieve 1 . by setting the module name as an observable and 2 . by publishing the node value in the mainContainer on a particular topic and in the detail module I need to subscribe to that topic and pass to the module with data attribute . So in the onclick event of the node of the tree I am publishing the node value and changing the module name value in the observable which successfully replaces the mainContainer with the detail module . However in the detail module even though I am subscribing to the topic that was published it fails to get hold of the value since this subscribe takes place in the detail module and the detail module has loaded once the user has clicked the node and so after publish has already taken place in the mainContainer .

Answer : You could consider passing the extra information as initialization data to your detail module . If your module returns a function constructor then the value will be passed to the function itself . If your module returns an object then it will be passed to the initialize function .

Anyone been doing this before .. . Answer : I found this : AMD Display Library SDK ADL for short . That covers ATI cards . http : developer.amd.com gpu adlsdk Pages default.aspx", "Question : On iOS I was able to create 3 CGImage objects and use a CADisplayLink at 60fps to do .. . .. . inside the ViewController and each time an image is set to the view s CALayer contents which is a bitmap . And this all by itself can alter what the screen shows . The screen will just loop through these 3 images at 60fps . There is no UIView s drawRect no CALayer s display drawInContext or CALayer s delegate s drawLayerInContext . All it does is to change the CALayer s contents . I also tried adding a smaller size sublayer to self.view.layer and set that sublayer s contents instead . And that sublayer will cycle through those 3 images . So this is very similar to back in the old days even on Apple or even in King s Quest III era which are DOS video games where there is 1 bitmap and the screen just constantly shows what the bitmap is . Except this time it is not 1 bitmap but a tree or a linked-list of bitmaps and the graphics card constantly use the Painter s Model to paint those bitmaps with position and opacity onto the main screen . So it seems that drawRect CALayer everything were all designed to achieve this final purpose . Is that how it works Does the graphics card take an ordered list of bitmaps or a tree of bitmaps and then constantly show them . To simplify we don t consider the Implicit animation in the CA framework What is actually happening down in the graphics card handling layer and actually is this method almost the same on iOS Mac OS X and on the PCs this question aims to understand how our graphics programming actually get rendered in modern graphics cards since for example if we need to understand UIView and how CALayer works or even use CALayer s bitmap directly we do need to understand the graphics architecture . .. . Answer : You ve got a reasonable intuition here but there are still several steps between contents and the display . First off contents doesn t have to be a CGImage . It is often a private class called CABackingStorage which is not quite the same thing . In many cases there are hardware optimizations going on to bypass rendering the image into main memory and then copying it to video memory . And since the contents of various layers are all composited together you re still a ways from the real display memory . Not to mention that modifications to contents just directly impacts the model layer not the presentation or render layers . Plus there are CGLayer objects that can store their image directly in video memory . There s a lot of different stuff going on . So the answer is no the video-card chip it s the PowerVR BTW does not take an ordered bunch of layers . It takes lower-level data in ways that are not well documented . Some things particularly parts of Core Animation and perhaps CGLayer appear to be wrappers around OpenGL textures but others are probably Core Graphics directly accessing the hardware itself . Once you get to this level of the stack it s all private and can change from version to version and from device to device .

To see the errors see here http : pastebin.com Gawkw4Uf .. . .. . All of them it seems to be related with fglrx dri.so . The long story is : I recently bought a Dell laptop with Ubuntu 14.04 and with a AMD graphics video-card . I could not install it . I tried a lot of ways to install it but failed . So when I type on terminal lspci grep VGA shows : .. . .. . So I am using my integrated graphics . and not my AMD graphic video-card .. . .. . When I type on terminal fglrxinfo : .. . .. . And according to this https : help.ubuntu.com community BinaryDriverHowto AMD in section 3 my AMD graphics video-card is installed and working . But it isn t . So back to my SDL problem when I was running my first SDL program an error libGL error : dlopen usr lib fglrx dri i965 dri.so failed usr lib fglrx dri i965 dri.so : cannot open shared object file : No such file or directory was shown . I opend this http : stackoverflow.com questions 34215617 error-running-simple-code-sdl question but I can t solve it . So I copyed the file i965 dri.so to directory usr lib fglrx dri . This makes this error disappear . So anyone has an idea why this is occurring I really want to put my graphic video-card to work . But after many many attempt I forgot my graphic video-card and just want to make my SDL code work well without errors or memory leak . Thanks Comment : I don t think your valgrind results related to driver problems although it may be but general rule is not every code piece is very good and if authors never used valgrind and didn t fixed detected problems - you re out of luck and will either have to live with that or blacklist this entries so valgrind woudln t report them again . Comment : I found this http : valgrind.org docs manual dist.readme-missing.html . Will solve just the first error or perhaps all of them . Comment : On the second thought it might not be an error at all but memory valgrind don t know about e.g . virtualised GPU memory .", "Question : I am interested in a way how to read GPU temperature graphics processing unit main chip of graphic card by using some video-card driver API Everyone knows that there two different chip manufacturers popular ones at least - ATI and nVIDIA - so there are two different kinds of drivers to read temperature from .

And this all by itself can alter what the screen shows . The screen will just loop through these 3 images at 60fps . There is no UIView s drawRect no CALayer s display drawInContext or CALayer s delegate s drawLayerInContext . All it does is to change the CALayer s contents . I also tried adding a smaller size sublayer to self.view.layer and set that sublayer s contents instead . And that sublayer will cycle through those 3 images . So this is very similar to back in the old days even on Apple or even in King s Quest III era which are DOS video games where there is 1 bitmap and the screen just constantly shows what the bitmap is . Except this time it is not 1 bitmap but a tree or a linked-list of bitmaps and the graphics card constantly use the Painter s Model to paint those bitmaps with position and opacity onto the main screen . So it seems that drawRect CALayer everything were all designed to achieve this final purpose . Is that how it works Does the graphics card take an ordered list of bitmaps or a tree of bitmaps and then constantly show them . To simplify we don t consider the Implicit animation in the CA framework What is actually happening down in the graphics card handling layer and actually is this method almost the same on iOS Mac OS X and on the PCs this question aims to understand how our graphics programming actually get rendered in modern graphics cards since for example if we need to understand UIView and how CALayer works or even use CALayer s bitmap directly we do need to understand the graphics architecture . .. . Answer : Modern display libraries such as Quartz used in iOS and Mac OS use hardware accelerated compositing . The workings is very similar to how computer graphics libraries such as OpenGL work . In essence each CALayer is kept in as a separate surface that is buffered and rendered by the video hardware much like a texture in a 3D game . This is exceptionally well implemented in iOS and this is why the iPhone is so well-known for having a smooth UI . In the old days i.e . Windows 9x Mac OS Classic etc the screen was essentially one big framebuffer and everything that was exposed by e.g . moving a window had to be redrawn manually by each application . The redrawing was mostly done by the CPU which put an upper limit on animation performance . Animation were usually very flickery due to the redrawing involved . This technique was mostly suited for desktop applications without too much animation . Notably Android uses or at least used to use this technique which is a big problem when porting iOS applications over to Android . Games of the old days days e.g . DOS arcade machines etc also used a lot on Mac OS classic something called sprite animation http : en.wikipedia.org wiki Sprite 28computer graphics 29 was used to improve performance and reduce flickering by keeping the moving images in offscreen buffers that were rendered by the hardware and synchronized with the monitor s vblank which meant that animations were smooth even on very low-end systems . However the size of these images were very limited and the screen resolutions were low only about 10-15 of the pixels of even an iPhone screen of today .", "Question : null .. .

Thanks", "Question : The problem : calling IDXGIOutput1 : : DuplicateOutput method https : msdn.microsoft.com en-us library windows desktop hh404600 v vs.85 .aspx returns DXGI ERROR UNSUPPORTED when you run an application using discrete graphics controller on a machine with switchable graphics . This answer http : superuser.com a 586811 shed some light on the issue . In short the discrete graphics renders only a part of the screen and sends the data to the framebuffer of the intergrated graphics controller -- in other words all output always goes through the integrated graphics controller . It seems that this is why DuplicateOutput returns DXGI ERROR UNSUPPORTED . I wrote a sample that gets all outputs and their videoadapters using winapi EnumDisplayDevices function https : msdn.microsoft.com en-us library windows desktop dd162609 28v vs.85 29.aspx directx IDXGIFactory : : EnumAdapters method https : msdn.microsoft.com en-us library windows desktop bb174538 28v vs.85 29.aspx IDXGIAdapter : : EnumOutputs method https : msdn.microsoft.com en-us library windows desktop bb174525 28v vs.85 29.aspx to compare on a machine with switchable graphics Intel HD 4600 NVIDIA 840M . This is the result : .. . .. . enter image description here http : i.stack.imgur.com VWUVN.png .. . .. . Not sure how much correct is my may of comparison but you can see that winapi says that DISPLAY1 belongs-to Intel card and directx says DISPLAY1 belongs-to NVIDIA card . One solution would be to duplicate the output of Intel card because everything goes through it but EnumOutputs returns no outputs for it . Currently there is a workaround : always run an application that uses Duplication API using the integrated graphics controller . The question : how to make DuplicateOutput work with the discrete graphics controller on a laptop with switchable graphics Or it is a limitation of the Desktop Duplication API Comment : How is your workaround a workaround If the desktop is running on the integrated card wouldn t it make sense that you d need to duplicate using that adapter to begin with What s your goal in duplicating the desktop using the discrete adapter Comment : @MooseBoys my goal is just duplicate the screen it does not matter using which adapter . usage of the integrated or discrete adapter is determined by NVIDIA settings not by me as a developer . by default for a heavy WPF app the discrete adapter will be selected and only its dxgi object will have the output duplicating which returns DXGI NOT SUPPORTED because actually everything goes through the integrated adapter -- see the picture . so the workaround is to ask the user to force usage of Intel card in NVIDIA Control panel . and the question is whether there is a way without workarounds .. . Answer : solved : .. . .. . unfortunately this issue occurs because the Desktop Duplication API does not support being run against the discrete GPU on a Microsoft Hybrid system . By design the call fails together with error-code DXGI ERROR UNSUPPORTED in such a scenario . .. .

I am an absolute beginner so if my question will seem strange it means I need some extra explanations . The book states : .. . .. . This book covers version 4.3 of the OpenGL specification . But my video-card Nvidia GeForce 9500GT supports only OpenGL 3.3 that is what I found when checking GPU Caps Viewer http : www.ozone3d.net gpu caps viewer . My question is : When learning from the book how do I know which functions and methods explained in the book I can use with my video-card and which ones I can t Comment : This depends on more than just the version of OpenGL that your card supports . The driver may not implement compatibility profiles in which case you must limit yourself to the core profile specification . Otherwise you will access to legacy stuff . There are two versions of the OpenGL specification beginning with GL 3.1 for precisely this reason . Comment : It is to be noted that the SuperBible sticks to core profile only . This is written upfront in the Introduction . .. . Answer : The functions which are part of OpenGL 3.3 are listed in its man pages http : www.opengl.org sdk docs man3 . If the function talked about in the book is not listed in this then that function would be part of OpenGL 4 or above . The man pages strictly have only what is absoluted mandated for that particular version of OpenGL . OpenGL 4 man pages http : www.opengl.org sdk docs man4 are also there to verify against . Another resource is OpenGL 3.2 reference card http : www.khronos.org files opengl-quick-reference-card.pdf which lists them neatly . You can compare it with the 4.3 reference card http : www.khronos.org files opengl43-quick-reference-card.pdf to know the difference .

Cmdlets are not inferior in any sense they are first-class functions if you will .. . Answer : cmdlets is used to compare PowerShell commandlets with with commands in traditional shells rather than as a comparison to something else in PowerShell . e.g . : .. . .. . A cmdlet pronounced command-let is a single-feature command that manipulates objects in Windows PowerShell . You can recognize cmdlets by their name format -- a verb and noun separated by a dash - such as Get-Help Get-Process and Start-Service . .. . In traditional shells the commands are executable programs that range from the very simple such as attrib.exe to the very complex such as netsh.exe . .. . In Windows PowerShell most cmdlets are very simple and they are designed to be used in combination with other cmdlets . https : technet.microsoft.com en-us library bb648597 v vs.85 .aspx .. . .. . and : .. . .. . A cmdlet is a lightweight command that is used in the Windows PowerShell environment . . . Cmdlets perform an action and typically return a Microsoft .NET Framework object to the next command in the pipeline . .. . How Cmdlets Differ from Commands .. . .. . Cmdlets differ from commands in other command-shell environments in the following ways : .. . .. . Cmdlets are instances of .NET Framework classes they are not stand-alone executables . .. . Cmdlets can be created from as few as a dozen lines-of-code . .. . Cmdlets do not generally do their own parsing error presentation or output formatting . Parsing error presentation and output formatting are handled by the Windows PowerShell runtime . .. . Cmdlets process input objects from the pipeline rather than from streams of text and cmdlets typically deliver objects as output to the pipeline . .. . Cmdlets are record-oriented because they process a single object at a time . https : msdn.microsoft.com en-us library ms714395 v vs.85 .aspx", "Question : We re using the stop-service cmdlet to kill a few services on our boxes .

Is there a way to have the stop-service cmdlet give up or timeout after a certain point I figure we can check afterward and if the service is still running use the kill-process cmdlet to provide a final chop . .. . Answer : Although Stop-Service does not have a timeout parameter the WaitForStatus method on the System.ServiceController class does have an overload that takes a timeout parameter documented here https : msdn.microsoft.com en-us library 35st9aw1.aspx . Fortunately this is exactly the type of object that the Get-Service command returns . Here is a simple function that takes a service name and a timeout in seconds . It returns true if the service stops before the timeout is reached and false if the call times out or if the service isn t present .", "Question : Suppose you are writing some PSCmdLet http : msdn.microsoft.com en-us library system.management.automation.pscmdlet 28v vs.85 29.aspx in C : .. . .. .

In order to avoid composing it each time manually I created a tool script library Helps https : github.com nightroman Helps .

Answer : Lately I have been developing Powershell scripts on a Window 8 machine instead of on a Windows Server 2012R2 which s I normally do . I have encountered two very strange things that never happened on the server . I know two questions in one post but I believe they might be connected . 1 . After a while CmdLets just stop producing any output whatsoever no error messages no verbose output . It doesn t matter if I run it in the lower command part or in the upper script editor and no difference if I run a selected part of the script or the whole thing . If I switch to a normal powershell the CmdLet works fine . If I restart Powershell ISE the CmdLet start working again but only for a like 2-5 execution not at all exact number after which it stops working again . Not all CmdLets behave this way mostly had problems with Storage related CmdLets Format-Partition Get-Disk Get-Volume and so on . 2 . After a while CmdLets that used to work fine in the upper script part of Powershell ISE just stops working . The CmdLets still work fine in the lower command part of the ISE GUI but does not work when used in the upper script editor even though they did just a second ago . And it doesn t matter if I run the whole script or just a selected part . And by not working I mean it can t even find the CmdLet The term is not recognized as the name of a cmdlet . The CmdLet is available in the Commands Side-Bar where it show up without any problem and I can access help for it . So any ideas what is going on here Comment : I ve run into quite a lot of issues debugging step-by-step . Sometimes the ISE cannot stop on a line because I don t know the parsing of it hangs it or something you cannot Debug Stop you have to restart the ISE . If I have a breakpoint on the line after that one and I run to that line it works and I can debug after that . Comment : I have not used the debugging feature in Powershell ISE at all when I encountered these problems . Comment : Do you have anything to show us that we can reproduce your issue Output is not very specific and I would like to see some of your output lines . ISE and Console are capable of having different profiles loaded so your situations could easily be different . Comment : Well when the CmdLet stops working there is no output whatsoever so nothing to show there and in the other case-when it stops working after a while it is the same output as-if you try to run Jump-Pig -height 4 -count 3 PS C : Jump-Pig -height 4 -count 3 Jump-Pig : The term Jump-Pig is not recognized as the name of a cmdlet function script file or operable program . Check the spelling of the name or if a path was included verify that the path is correct and try again . + Jump-Pig -height 4 -count 3 + ... . + FullyQualifiedErrorId : CommandNotFoundException Comment : Well that error is very specific . The cmdlet is not present when it is called . Is it declared before it is called If you don t show us a specific example that we can reproduce there is going to be a lot of back and forth here .", "Question : I m looking for an explanation on why parameter binding fails when using script blocks without specifying named parameters in a piped Rename-Item cmdlet .

Why does this work : .. . .. . but this does not work : .. . .. . Error : .. . .. . The Rename-Item syntax seems pretty straightforward to me ie . two mandatory positional parameters : .. . Answer : I think you re confusing the parser by giving it the name from the pipe and as a positional parameter simultaneously . The cmdlet will accept the name from the pipeline or as a positional or named parameter . Since you re piping input into the cmdlet it s assuming that s the name to use . If the name is coming from the pipeline then there should only be one additional positional parameter Newname .

My CPU is pretty slow - it s Pentium U5400 However with Resharper 5 i didn t seen such lags . I was working pretty comfortable . Now I see lags . Is it because CPU is too slow or this is Resharper bug If Resharper 6 has new features which require CPU time while i m typing anything even comments It lags always . While I type comment in VS devenv.exe process takes 70 of CPU . I will test how Resharper 6 works on my desktop i7-860 in a moment . The question is why Resharper 6 takes much more CPU than Resharper 5 and what nice features I have for that upd on i7-860 while typing VS takes 10 of CPU what 70 of U5400 . So the question is elligable . why Resharper 6 takes much more CPU than Resharper 5 .. . Answer : Do you use ReSharper 6.1.1 If not then you should because it contains many performance fixes . If you use ReSharper 6.1.1 and still experience lags try to disable other Visual Studio extensions and plugins . If there is no extensions and plugins other that ReSharper 6.1.1 and typing is still slow then please make a performance snapshot and send it to JetBrains as described here here http : confluence.jetbrains.net display ReSharper ReSharper+Profiling+Instructions .

Also note that we re only using Resharper Ultimate 2016 . I want to confirm if this is intended or not . It is possible it could be problems due to our system but so far no other program have given varying install paths . .. . Answer : The installation path of R depends on which installation mode has been used - per-user LocalAppData or per-machine https : resharper-support.jetbrains.com hc en-us articles 206545259-How-do-I-install-ReSharper-for-All-Users-on-current-PC- Program Files x86 .

I have to actually have cursor on what I want to change and wait for the pencil or light bulb to show up .

Reopen visual-studio . Resharper should be indicating all the recommendations and smells as it did before you updated it . Hope this helps .", "Question : I recently installed Resharper 6.1 in VS-2010 . I m using it with a rich web application with an Azure-based C back end and JQuery and other Javascript libraries on the front end . I love the way Resharper can parse my JS files and provide statement completion and the code-analysis has identified a number of style and syntax issues that I ve already fixed . HOWEVER I am now experiencing MAJOR typing latency in my IDE as Resharper works its magic . I have a quad core Intel i5 dev box with 6GB of RAM and the CPU is thrashing and memory usage shoots way up . The latency is so bad that any benefits from improved statement completion in JS files are lost . I have a number of other JS plugins that I ve temporarily disabled but this didn t help . I then turned off Resharper s Intellisense and reverted back to VS-2010 . This helped marginally but Resharper is still making the editing experience latent . I ve run out of ideas about how to improve its performance . Maybe it s not possible to speed things up.. . On paper it s everything I ve been looking for . But in practice it has turned my speedy development-machine into a 286 box from the 1980 s running Windows 3.1 . And as someone who was using 286-based Intel PC s back in the 1980 s...that is not a good thing Comment : Quick update : I just uninstalled ReSharper so I can try out some other ideas . I want to see how far I can get with reference path directives in VS-2010 for JS Intellisense e.g . reference path MyScripts.js I haven t thrown in the towel completely but if I can find something that s only a quarter as cool as ReSharper but that doesn t destroy my real-time editing experience in the IDE that ll be good enough for me . .. . Answer : I don t mean to be facetious but my recommendation is to uninstall the thing . My personal take is that all the benefits that ReSharper offers are marginal compared to the headaches that it creates . In my previous company I was supposed to use it but the moment I installed ReSharper it completely hijacked the Visual Studio native intellisense . My productivity actually went down instead of the other way around . Trying to figure out this thing through zillions of settings was quite frustrating . I then went around the team and asked what everyone else thought of it . Two out of three devs hated it and had already uninstalled . Comment : Accepting this as the answer . I ended up uninstalling ReSharper and am now using Reference directives in my JS files to get native VS-2010 JS intellisense . It s a manual per file process but now I have a responsive IDE again . My own view is that ReSharper is trying to do too many things at once . As you noted it hijacks the editor and in my case made it totally latent and sluggish .", "Question : ReSharper 6.0 seems to be conflicting with Symantec Endpoint Protection on my XP Pro SP3 machine at work .

Not bad . Do I get a commission Hehe.. . Comment : I see you work for JetBrains .. . is there any reason why this ability isn t built into ReSharper itself After all the decompiling engine is all there surely it would just need some kind of GUI . Comment : @DanielHilgarth Well done and an upvote from me . It s no problem though to be faster than me as I m a total slowpoke . Comment : @SirCrispalot I guess integrating this into VS would be an overkill : VS and ReSharper is intended to work with solutions projects and references not with individual files .

Seeing the value in code as it was originally written is beneficial What a difference a pair of new eyes have .. . Answer : If you re prepared to venture into ReSharper plug-in dev territory this yields a very very simple plug-in that would take minutes to implement .

You just select that category and drag the template out to the All category . and I feel I must also quote a user comment : .. . .. . Your solution works but is not intuitive at all . Quite . Comment : As a side note at least in R v10 this seems to only work if you drag one at a time.. .", "Question : I want to jump out from quotes . When I was not using ReSharper Tap key helped to jump out from double quotes but it is not working when using ReSharper . Of course I do not want to use right arrow key . Help please . reharper http : i.stack.imgur.com viO6Y.png Comment : What is tap key Comment : @Snowbear I think he meant Tab .. . .. . Answer : If you re looking to jump out of the method arguments altogether use Ctrl+Shift+Enter Complete Statement . If your intention is to quit the current string value to start entering the next argument then I m not sure anything apart from the right arrow or Ctrl + right arrow will work . What s the Tap key btw Comment : tap key works the same as Ctrl + right arrow key . That is what I was looking for . ctrl+shift+enter seems useful but it does not do anything in my vs Comment : Weird : the shortcut for Complete Statement is the same between both keymaps . Try going to Tools Options Environment Keyboard and see if ReSharper.ReSharper CompleteStatement is assigned this shortcut it could possibly be used by another command related or not related to ReSharper . Btw here s an old yet useful post on using Complete Statement in different scenarios : blogs.jetbrains.com dotnet 2008 05 http : blogs.jetbrains.com dotnet 2008 05 resharper-in-detail-complete-statement-scenarios", "Question : I know this has been asked before but there was no solution to the problem and it was last year so I thought maybe someone has found something to solve this by now . I am using VS2010 with SP1 . before installing the SP1 there was no problem . if I uninstal re it works fine . I have an ASP.Net website and some other projects . The classes from the other projects are not recognized resharper suggests using the other project so I do so it puts it up at the usings then the using also gets a cannot resolve symbol . I have tried the suggestions they gave in 2011 here http : stackoverflow.com questions 5539131 resharper-cannot-resolve-symbol-eval-in-vs2010-sp1 but nothing . if I delete the Resharper . and restart vs it will work for 5 seconds then all red again.. . .. . .. . hope someone found a solution to this since then...thanks .. . .. . Edit : I have noticed it does this with Web Services Comment : Resharper can not resolve symbol even when project builds http : stackoverflow.com questions 15713167 resharper-can-not-resolve-symbol-even-when-project-builds .. . Answer : I was having the same problem with one of my projects . I reported the issue to JetBrains and they requested a VS solution which has the problem . So I decided to spend a few hours trying to narrow down the problem as much as possible . I found out that the issue is related to a tool I use which strips out information from .DLLs . If I don t strip the .DLLs Resharper works fine without showing any cannot resolve symbol errors . However If I do strip the .dll then ReSharper starts to show these cannot resolve symbol errors . In both cases Visual Studio compiles the program and the program runs fine . I am working with JetBrains to get the issue resolved . In the mean time I am able to workaround the problem by using versions of my .DLLs which do not have any information stripped out of them .", "Question : I am using Specflow http : specflow.org to write some integration tests and I would like to run a single Scenario . Is there any way to run a single scenario with Resharper 6 BTW I configured specflow to use MSTest . My Specflow test looks like : .. . .. . I want to run only the first scenario . .. . Answer : If you are running with ReSharper as I am I just open the Feature file the right-click anywhere within a Scenario and select Run Specflow Scenarios from the pop-up menu . It runs just the one scenario you are in . Please note I am using ReSharper to run the tests .", "Question : I downloaded StyleCop 4.6.3 which integrates with ReSharper 6 and the results are really fantastic However on a specific project I would like to disable the StyleCop warnings temporarily and enable again later on . Is there any way of doing this I can t seem to find it on the ReSharper menu options etc . .. . Answer : You can use different Settings.Stylecop settings for each project just create one that ignores all the rules . Right click on a project and select Stylecop settings to modify them . I think you can also disable plugins by unticking them from ReSharper- Plugins.. . in version 5.1 not sure if it s the same in 6.0 Comment : That did it : Thank you I unchecked it from the Plugins and it worked . The solution with using different Settings.Stylecop settings is also interesting . Anyway the combination of StyleCop and ReSharper rocks : Thanks again .", "Question : I renamed a folder and updated my namespace declarations but Resharper 6 keeps trying to tell me that the namespace should be a reflection of how it was before the rename . Where on earth is it storing the file location data Comment : I suggest that you delete all .ReSharper files . Resharper will recreate them from scratch without the garbage . Comment : I thought I had . I suppose I should give it another go . Comment : Did it work I will move my comment into an answer . Comment : It s all in .ReSharper files . If all were deleted and you still get a namespace issue I believe it is indeed related to your folder s structure.. . Comment : This also happened to me using Resharper 8.2.3 . The problem is that it was ignoring folders with a space in the name . So MyProject Service Contracts Common was resolving to MyProject Common instead of the expected MyProject Service Contracts Common .. . Answer : I also had this problem with a folder namespace and none of the above steps fixed it . In my case I had to do this in Visual Studio : .. . .. . Right-click the problem folder in the solution-explorer to open the properties .. . Ensure the Namespace Provider is set to true .. . .. . This fixed the ReSharper issue for me and I was able to adjust namespaces as normal .", "Question : ReSharper 6 creates folders like ReSharper.projectname with the files and folders below in it . That caused a lot of problems with MSDeploy and source control in general . I had to add ignore rules everywhere . What s the right way to prevent that from happening Is switching back to Visual Studio Intellisense enough .. . Answer : Resharper - Options go to the General tab and change store caches in to system TEMP folder instead of solution folder Comment : I was lost in the options dialog thanks", "Question : ReSharper 6 creates folders like ReSharper.projectname with the files and folders below in it . That caused a lot of problems with MSDeploy and source control in general . I had to add ignore rules everywhere . What s the right way to prevent that from happening Is switching back to Visual Studio Intellisense enough .. . Answer : Resharper 9 just added a new option Custom folder so you can put the cache anywhere event in ramdisk", "Question : I ve searched around a bit for this and tried a few things and can t get it to work without turning some stuff off that I want on . Normally I let Resharper have its way with namespace optimizations . In a Service implementation that s mapping DTO s to Domain Model objects it s a nice visual to create an alias for each . That way when it s late and you re sleep deprived seeing Dtos.Customer and DomainModel.Customer helps . When I run code-cleanup it changes those to : .. . .. . Does anyone do this or something similar and keep R from whacking it .. . Answer : This is something ReSharper will do when you let it : shorten references on code-cleanup . Even though this behavior might be unwanted for you it s technically seen correct . Because in your code it ll shorten something . And that s what the algorithm is supposed to do . This is how the algorithm works that causes this result : .. . .. . 1 . Resharper finds a reference that can be made shorter you ve not given me enough code to exactly tell you where but that doesn t matter . 2 . After shortening it needs to assure that the object can be resolved so it adds a new using for it using Customer MyProduct.Core.Domain.Model.Customer in your case . 3 . Resharper detects that using Dtos MyProduct.ServiceModel.Dtos is no longer in use after all the other using covers your shortened reference . And removes it . This is what I suspect is causing this . I cannot be 100 certain without seeing the actual usages in code . But this is most likely the cause of the refactoring . Comment : I see I also see why it s getting rid of the using Dtos alias . Something else needs a ref to MyProejct.ServiceModel . I suppose creating a code-cleanup profile that doesn t optimize using-directives would work .", "Question : I renamed a folder and updated my namespace declarations but Resharper 6 keeps trying to tell me that the namespace should be a reflection of how it was before the rename .

I do need to be able to respond to multiple simultaneous requests . I would like to use HTTPS . In looking on stackoverflow it seems I can potentially go with BaseHTTPServer and ThreadingMixIn or Apache and mod-wsgi . I already have Apache installed but have never configured it . Are there compelling reasons to go the more complicated Apache route more complicated to me because I will need to do research on configuring Apache and getting mod-wsgi going but already have a test instance of BaseHTTPServer up and running or is it equally safe secure very important and performance-oriented to use BaseHTTPServer for something so simple .. . Answer : BaseHTTPServer is not a production grade server . If you don t understand how to set up Apache but want to get something with mod-wsgi running quickly and easily then you probably want to look at mod-wsgi express . This gives you a way of installing mod-wsgi using Python pip and also provides you a way of starting up Apache mod-wsgi with a auto generated Apache and mod wsgiconfiguration such that you don t even need to know how to configure Apache . The next version of mod-wsgi express to be released version 4.3.0 likely released this week can even set up a HTTPS site for you with you just needing to have obtained a valid certificate or generated a self-signed certificate . I would suggest if interested you use the mod-wsgi mailing list to ask for more details about using mod-wsgi express for running a HTTPS site . http : code.google.com p modwsgi wiki WhereToGetHelp tm 6 Asking Your Questions .. . .. .

Comment : Unlike Apache+PHP BaseHTTPServer will not just serve anything you put into that folder . You have to either do it yourself as Matthew described or serve protovis.js from a different server could even be a SimpleHTTPServer running on a different port . .. . Answer : Make sure that you are serving protovis protovis.js using your BaseHTTPServer . Basically the browser will see the line script type text javascript src protovis protovis.js script when it is reading the html output it gets and then request that the server actually send the protovis protovis.js file . I didn t see the python code in that github download so I can t specifically show how to do this in the context of your code but check out SimpleHTTPRequestHandler . Using that you can add to the do GET method to have the server send protovis protovis.js when it is requested that is when self.path is protovis protovis.js .

Answer : It would be excellent to configure the http server with the following callbacks : .. . .. . before starting the server .. . after starting the server .. . before stopping the server .. . after stopping the server .. . .. . Bear in mind that the OS will start accepting and queuing TCP connections the moment the socket starts listening which is done in the constructor of BaseHTTPServer so if you want to perform lengthy tasks before starting the server it s probably better to do them before the OS starts accepting connections . There s a server activate method which makes the call to socket.listen so it s probably best to override that . Similarly the OS will continue to accept connections until the call to socket.close so if you want to be able to define a pre-stop handler which has the capacity to prevent itself from being shutdown it s probably better to use the server close method rather than calling socket.close directly . I ve put together a simple example using class methods on the request handler to handle the four new events although you can move them somewhere else.. . Note that I ve also moved the call to the constructor into its own try...except block since the server variable won t exist if you hit CTRL-C during its construction .

Use perl : .. . .. . perl -e @T localtime time-86400 printf 02d 02d 02d T 4 +1 T 3 T 5 +1900 .. . .. . .. . 2 . Install GNU date it s in the sh utils package if I remember correctly .. . .. . date --date yesterday + a d m Y read dt .. . echo dt .. . .. . .. . 3 . Not sure if this works but you might be able to use a negative timezone . If you use a timezone that s 24 hours before your current timezone than you can simply use date . Comment : Sorry I m on HP-UX Comment : @Chris : I assumed it wouldn t be a GNU compatible date but since you didn t specify the Unix variant I simply guessed With HP-UX your options are a little more limited date doesn t have these options so Perl might be the best option .

The simplest solutions seem to use perl.. . but i don t know how to modify them as they re quite arcane . Thanks .. . Answer : What I would do would be to actually grab the source code for date from Linux and compile it under HP-UX as betterdate then just use that . I haven t used HPUX since version 9 but it was getting a bit long in the tooth even way back then . The great advantage with open-source is that you can just recompile it under the target-platform . Now this may not work due to incompatibilities with API s and such but I d be looking at this as a first attempt . The work that date has to do is fairly simple in terms of what APIs it would need to call . Then you have the full power of Linux date at your disposal . Comment : This would be the best solution especially for the rest of the world : but the client won t accept it . Comment : What will they accept Are you allowed to compile any C Can you use the other standard tooling awk sed grep et al Or does it have to be ksh on its own presumably date is okay Comment : It has to be a script it s out of the question to start an homologation proccess for a third-party program.. .", "Question : I am trying to compile a console C application on HP-UX machine using the aCC compiler HP C aC++ B3910B A.06.26 .The compilation always failing with the below error : .. . .. .

Answer : snprintf http : en.cppreference.com w c io fprintf was introduced in C99 and is defined in stdio.h so your compiler must support that version of the C standard . If it does not support C99 then use sprintf instead . Comment : This is version 6 of the compiler which is documented to support C99 . Comment : @paxdiablo I am unfamiliar with that compiler any required compiler switches like gcc Comment : According to HP the compiler HP C aC++ B3910B A.06.26 support C99 . I am not developping the app we are just trying to compile it this is a bit strance because I succeded to compile the same code with an older version of the same HP compiler .

After a small change to ext pty.c it compiles successfully albeit with a lot of warning messages about 5K .

Pid 3044 was killed due to failure in writing the signal context - possible stack-overflow . .. . Illegal instruction .. . .. . From googling this problem the Illegal instruction is just a signal that the system uses to kill the process and not related to the problem . It would seem that there is a problem with the re-establishing the context when calling the signal handler . Bringing the core up in gdb doesn t show a particularly deep stack so I don t think the possible stack-overflow is right either . The gdb stack backtrace output looks like this : .. . Answer : Answering my own question : .. . .. . The problem was that the stack being allocated was too small . So it really was a stack-overflow . The sendsig function was preparing a context structure to be copied from kernel space to user space . The useracc function checks that there s enough space at the address specified to do so . The Ruby 1.9.1-p0 code was using PTHREAD STACK MIN to allocate the stack for any threads created . According to HP-UX documentation on Itanium this is 256KB but when I checked the header-files it was only 4KB . The error message from useracc indicated that it was trying to copy 20KB . So if a thread received a signal it wouldn t have enough space to receive the signal context on its stack .", "Question : I m trying to get stack size of current thread in my application running on HP-UX 11.31 .

Comment : I am also looking for it . Comment : so it s a common issue . Hopefully someone can spread some light on this . .. . Answer : This post is old but I think it is good to leave a foot print for others : .. . .. . There is this new company called NVdrones which created a peace of hardware that you can attach to any drone you need physical access to the flight controller and once you do that you can use their SDK Arduino Java Android and Javascript to write your app without the need of hacking soldering or anything else . It is just plug and play . Another benefit is that you are not locked with a specific drone DJI SDK or 3DRobotics SDK you can use the board on anything you want . Which gives lots of flexibility . The developer site is http : developers.NVdrones.com .. . .. . Hope this helps ." ] }

Answer : Take note : Every Handler is bundle with one Looper which only one Looper may be created per thread . So you can create an Handler instance by constructor of Handler Looper . When using Handler to create one instance the default Looper is from the Main UI Thread on which current Activity s run . As for your codes above you defined showDialog String message in an Activity right So that means this method will be called on the Main UI Thread . Consequently when you create a Handler instance by constructor of Handler inside showDialog String message the Looper from the Main UI Thread will be bundled with the Handler instance by default . That means Looper.prepare is redundant and then removing Looper.prepare will solve your problem . Comment : Not exactly . Handler uses the current thread and throws an exception if the current thread is not a Looper . That s normally but not necessarily the main thread . Comment : Yes Handler will bundled with the Looper created by the Thread on which showDialog String message run . In this case showDialog String message run on the Main UI Thread .", "Question : I m now trying to resurrect one project . There was an exception on getMainLooper .. . I thought that may be there s a problem with MainLooper initialization and added Looper.prepareMainLoop before that .

But I didn t understand why .. . .. . In fact I don t get the difference between this two things . I think that on the place where getMainLooper was used in my project it s the best place for the true main looper of the application but I got what I got. . Please explain . Thank you for your attention .. . Answer : The difference is that Looper.prepareMainLooper prepares looper in main UI thread . Android applications normally do not call this function . As main thread has its looper prepared long before first activity service provider or broadcast receiver is started . But Looper.prepare prepares Looper in current thread . After this function is called thread can call Looper.loop to start processing messages with Handler s . So in your case you had two threads - X and Y . The X thread is the main UI thread that has its looper already prepared by Android . When you are in Y thread and you re calling Looper.prepareMainLooper you re trying to prepare looper in X thread main thread . This fails because X s looper is already prepared . But when you call Looper.prepare in Y thread you re actually preparing looper in Y thread and therefore ready to call Looper.loop .", "Question : Today I read some blogs and source code about how Handler Looper work together . Based on what I ve learnt we can have only one Looper on each thread by using the ThreadLocal magic . Usually Handler is initiated in main thread or else you must manually start or saying prepare the Looper on a separate thread and then loop it up . What really confused me was the loop in main thread . As I read this in the source code of Looper . It s an endless loop to handle the message-queue and then dispatch messages for callbacks to handle . According to this http : stackoverflow.com a 5193981 2290191 Handler and it s Looper run in the same thread . If there is an endless loop on the main thread wouldn t it block the entire UI system I know that I must be so silly to miss something . But it would be lovely for someone to reveal the secret behind this . .. . Answer : Actually the Looper in the main thread is what allows drawing . When a view is invalidated a message is passed to the main Looper telling it that a draw was requested . When the Looper processes that message the actual drawing occurs . The reason other activity that holds up the UI thread holds up drawing is that it prevents the Looper from processing that draw message . This is more or less how drawing works in any event based system from Windows to Mac to Android . Why not draw immediately instead of sending a message Performance . Drawing is slow . If you do multiple changes in response to an event you don t want to redraw the screen for each one . Doing it this way means you bunch all of your redraws for handling a single event into 1 redraw . For example if you set the text of 1 view and the image of another they ll both be redrawn at the same time and only once . Comment : I don t think you read my question carefully . I mean if there is for-loop on main thread how is that possible to send messages to draw the UI Comment : I did I don t think you understood my answer . One of the messages to the looper causes the draw . Draw is a special message sent to that looper . Comment : Or put another way- what you re thinking of as the main thread is actually that Looper processing messages and calling your code in response to it . That s a technique called an event-loop or message loop which is common in event-driven programming . Here s a detailed explanation of Android s mattias.niklewski.com 2012 09 android-event loop.html http : mattias.niklewski.com 2012 09 android-event loop.html Comment : Thanks @Gabe Sechan that blog really explains everything . I used to figure all this out with a multi-thread model . Like the events must be sending from another thread and the main thread waits for events to handle .

Answer : Looper.loop is an infinite-loop so when you re running this off the main UI thread the code execution basically stops there preventing the UI from being displayed . Not sure what you re trying to accomplish and I m not at all too familiar with Looper and threads but here are a few articles I read about Looper . http : mindtherobot.com blog 159 android-guts-intro-to-loopers-and-handlers http : corner.squareup.com 2013 10 android-main-thread-1.html Comment : ur post is very relevant to the answer but not completely . i know Looper is already running looping over the messages and im calling Looper.loop I just want to know what is does that button drawing wont happen on the ui-thread means does that Looper get reset or removes some message . exactly what happen when we call Looper.loop on a thread looper when its already looping . Comment : @sush because when you call Looper.loop you are blocking the rest of the code . In other words you re blocking the main thread from continuing . It won t ever get to onStart and onResume of the activity because the Looper.loop call you made is waiting for messages . The reason you get your Toast message is that you created a message to display the Toast then you called Looper.loop and now all it is doing is waiting and will pick up your Toast to display after 10 seconds and then keeps on waiting . Comment : @sush so one way to visualize this is add an onResume override in your activity and put a debug breakpoint in it . When you debug your app you will never hit the onResume as the code execution is still on your Looper.loop line .", "Question : Consider the following snippet : .. . .. . A little background : I m doing some processing on the UI thread where I will need to ping a large about of devices and do something with the result . I need to perform the requests in parallel to be efficient . Question : If one of these use cases somehow executed fast enough and made a callback before I was able to hit Looper.loop would the message be queued or just lost Callbacks are being posted back to this thread by the handler posting a runnable to the original thread . .. . Answer : Assuming you have invoked Looper.prepare prior to your useCaseProvider delivering results you should be fine . If Looper.prepare was not called you should be seeing RuntimeException being thrown . The Looper object is tied to a thread-local which hosts the message-queue . The Looper.prepare function will construct this message-queue at which point you can begin queuing up messages . Once you fire Looper.loop that s when those pending messages will begin to execute . Looking at the snippet I m not too sure how things are tied together . Generally you want to construct a looper like this : .. . .. . I m assuming your thread pool is then a pool of MyThread threads each of which have their own Looper . The thread pool should initialize your threads so once you deliver a Runnable to be executed by your thread the run method should have the Looper initialized . On the other hand if you wish to associate your Handler with a particular looper ie . you are not constructing the Handler within a thread like above then you should be passing the Looper thread in to the constructor like : .. . .. . If you don t specify that then the handler uses the thread in which it was created to grab that thread s Looper from the ThreadLocal object . Lastly if your intentions are to have messages delivered on the Handler which is associated with the UI thread then you should not be concerned about calling Looper.prepare or Looper.loop . This is handled by the Activity . Comment : So basically in his snippet processing messages on the MessageQueue will be delayed by the execution-time of the for-loop . Comment : Pretty much . Any attempt to deliver to an uninitialized Looper will result in a runtime exception . Depending on what s required an IntentService might be a better way to go .", "Question : I need to understand about the Looper . Looper will consult appropiate handler to to send and process Message and Runnable objects associated with a thread s MessageQueue . By default a thread does not have a message loop associated with it hence doesn t have a Looper either .

Does it mean that the task runnable is not put in the queue what s the difference of above code with this .. . .. . both of them accessing a same handler . They both work fine . Comment : A Thread does not need a Looper to post to another Thread s Handler if that s what you re asking . The Handler s in your examples are for other Thread s whichever Thread s you re creating them on . Comment : Hello I m confused now so what s the difference on my second example there I m invoking Looper.prepare explicitly but without it it still works Comment : Creating a Looper for a Thread means that other Thread s can post to it . The Looper in your example isn t really doing anything since you re not posting anything to a Handler created there which is why you don t see a difference . Comment : Mike whats that other Threads can post to it in this context could you put it as answer please Comment : Well there are plenty of answers here that already cover this so I d rather find a duplicate than post a repeat answer . Anyway in your second example since you re starting a Looper in that Thread you could create a Handler for that Looper pass it to another Thread and then that other Thread can post to it . Your example Thread s are posting Runnable s to whichever other Thread the Handler s are created for . They re not posting them to themselves . .. . Answer : Creating a Looper for a Thread means you re setting up that Thread to receive messages from other Thread s . Both of your examples are behaving exactly the same because the you re not sending anything to the Thread in the second example . That is the background3 s Looper isn t really being used . In both examples you re posting a Runnable to a Handler that was created for the main Thread s Looper . You re not creating that Handler for e.g . background2 . That Handler belongs-to the main Thread and its Looper and anything you post to it will be put into the main queue and run on the main Thread . The only difference in your examples is that the second Thread has a Looper and you could post to it if you wanted to . To do that you would create another Handler that belonged to background3 s Looper and post to that . You re not doing that though so the second Thread just continues to run without doing anything else . A Thread doesn t need a Looper simply to post to another Thread s Handler which is really all that your examples are doing . That other Thread - the main Thread in this case - has already prepared and started its Looper . You re just sending Runnable s to it and you don t need a Looper of your own to do that .

I suggest you read the Activity and Service articles in the Api guides and then read Handler and Looper . It also helps if you have an understanding of what a thread is not an android thread but a thread in general...e.g . POSIX . .. . Answer : What is Looper .. . .. . Looper is a class which is used to execute the Messages Runnables in a queue . Normal threads have no such queue e.g . simple thread does not have any queue . It executes once and after method execution finishes the thread will not run another Message Runnable . Where we can use Looper class .. . .. . If someone wants to execute multiple messages Runnables then he should use the Looper class which is responsible for creating a queue in the thread . For example while writing an application that downloads files from the internet we can use Looper class to put files to be downloaded in the queue . How it works .. . .. . There is prepare method to prepare the Looper . Then you can use loop method to create a message loop in the current thread and now your Looper is ready to execute the requests in the queue until you quit the loop . Here is the code by which you can prepare the Looper . Comment : So looper could be used to update the main thread with lets say.. . a download percentage 10 20 30 .. . etc . Essentially feedback which you could feed into a progressbar Comment : An AsyncTask is better for that purpose and less complex as it encapsulates all the thread managing . Comment : Should have @Override annotations before the run and handleMessage methods Comment : The documentation indicates that you must call looper.quit .

So I think it is not the duplicate of that question . Thanks. . Comment : developer.android.com reference android os Handler.html http : developer.android.com reference android os Handler.html Comment : That question is about only Handler and Thread but didnt explain about Looper and its behavior . Comment : @jettimadhuChowdary - Take a look at the answers and see if they have adequately answered your question before voting to reopen . .. . Answer : premise : A Handler is not a Thread . .. . .. . A Looper is an Object associated with the Thread from which it is created . As you can guess by it s name a Looper is going to loop over something but looping over what Over a message-queue also associated with the same thread . Next question is : How can I put something in this message-queue And here is the Handler . A Handler is always associated with a Looper which one we will see it later . The Handler can play 2 roles and that s maybe why it is confusing .. . .. . First role of the Handler : you must use it to post messages to it s associated Looper in fact to it s message-queue . You can use one of the various Handler.sendMessage or Handler.post methods to do that . and note the sendMessageDelayed postDelayed methods allowing you to post a Message http : developer.android.com reference android os Message.html Runnable http : developer.android.com reference java lang Runnable.html to be handled in future .. . .. . What is the Looper associated with a Handler Very easy : the Looper of the current Thread if you don t specify it but you can use the constructor with a Looper : new Handler Looper looper http : developer.android.com reference android os Handler.html Handler android.os.Looper and in this case the handler is associated with looper in argument . At this point we know that : .. . .. . a Looper is associated with one and only one Thread .. . a Looper loops over it s associated message-queue .. . as a consequence : there is one message-queue associated with one Thread as soon as we have a Looper for the Thread .. . a Handler is always associated with one Looper .. . a Handler can be used to post message to the message-queue .. . .. . .. . .. . Now let s see the second part : the message processing message handling . First let s look at the Looper looping over it s message-queue . Is there is a message in the queue Yes i.e . at some point a Handler has posted it . Is it time to handle this message if it was posted with postDelayed http : developer.android.com reference android os Handler.html postDelayed java.lang.Runnable 20long If not wait a little . If it is time : let s dispatch this message . Remember that I told that the Handler have 2 roles.. . and here is the second role of the Handler : a Handler as indicated by it s name can handle messages . To be able to handle custom messages you must subclass the Handler class and implements the handleMessage Message http : developer.android.com reference android os Handler.html handleMessage android.os.Message method . So the Looper will simply call the handleMessage of the Handler who posted the message and it s job i.e . dispatching the messages is finished the Looper can move on to the next Message in the queue . At this point you may ask yourself : OK I see the interest of delayed messages but why should I use all this stuff for things to do immediatelly Remember that the Looper is associated with one Thread and the handleMessage will be called in this Thread . On the other hand the Handler.post can be called from another thread . So this mechanism is also very convenient to schedule a job in thread X from thread Y . particularly useful if the job is affecting the UI and MUST be run in the UI-Thread .. . .. . Final note .. . .. . UI-thread is a first class citizen : .. . .. . On Android there is a main Looper associated with the main Thread i.e . the UI-thread . You can get a reference to it with Looper.getMainLooper so you create a Handler associated with the main Looper with : .. . .. . and with that you can post a message from any thread to the UI-thread .. . .. . Should you really use messages and subclassing Handler to use this No not always .. . .. . You don t always need to create message explicitly to use this mechanism . You can easily post a Runnable http : developer.android.com reference java lang Runnable.html to a Handler and in this case you don t even need to override the handleMessage Message because the default implementation of the Handler will simply execute the Runnable under the hood : a message http : developer.android.com reference android os Message.html is created with the Runnable associated to it .. . .. . Looper must be prepared to receive messages .. . .. . By default there is no Looper on every thread by default there is only a prepared one in the UI-Thread . To prepare a Looper for the current thread : call Looper.prepare http : developer.android.com reference android os Looper.html prepare Comment : This is awesome.. . thank you @ben75 for making this lucid explanation", "Question : I have read that a service is different from thread because it is not affected by the current activity . But threads are . But Looper is also same like a service which doesn t get affected by the current activity and they both run in background . So what basically differs a service and a looper.. . Please help me out . I am totally confused in these topics . .. . Answer : Looper is a class which is used to execute the Messages Runnables in a queue . Normal threads do not have any queue . For example Simple threads do not have any queue . They are for one time execution and after the end of the code the thread will be stopped killed and it will not able to run another Message Runnable . Usage If you wants to execute multiple messages Runnables then you should use the Looper class which is responsible for creating a queue in the thread . For example . If you are writing an application which downloads files from the internet then you can use Looper class to put all the files in the queue to be downloaded . Service runs in a different process Say in an application if it gets crashed or the process in which application was running gets killed then Async Task looper will also be killed but not Service because service was running in a differnt process . Looper run in the same thread as of app unkike Service .Also Android Recommends to use Async task rather than Loopers . Comment : Can we use services in this case or AsyncTask class because AsyncTask class is also responsible for handling multiple tasks simultaneously. . Comment : The main difference is Service runs in a different process Say in an application if it gets crashed or the process in which application was running gets killed then Async Task will also be killed but not Service because service was running in a differnt process . Comment : And how about Looper . If our app is crashed will looper also get crashed. . Comment : Looper run in the same thread as of app unkike Service If the process in which app was running gets killed then looper will also be killed but service will remain running as service runs in a different process .

Answer : Android Looper is a wrapper to attach MessageQueue to Threads and it manages Queue processing . It looks very cryptic in Android documentation and many times we may face Looper related UI access issues . If we don t understand the basics it becomes very tough to handle . Here is an Article which explains Looper life cycle how to use it and usage of Looper in Handler- http : prasanta-paul.blogspot.kr 2013 09 android-looper-and-toast-from.html Hope it helps .

I have seen many places saying not to use Looper with Handler but to use AsyncTask or some similar non-main thread methodology . So shall we ever use Looper or not If yes when me have to use it not must or should Only when passing UI update message from the thread to the main thread or there are some other cases as well Comment : some similar non-main thread methodology . Which is the key to answer your question : too much work on your main thread may cause crashes Comment : That was my idea years ago when I started learning Android . But now each time I am interviewed for a senior position I am asked do you use Looper why and when . Obviously all seniors in those companies are using it.. . which is the reason I asked the question .

It can t be onDestroy of any of the activities . If I don t shut it down and the process is not killed by OS - new Looper may be created on next app launch and this one will leak . Alternatively create once store in a static field never quit let it leak once . The last one seems to be the safest and easiest to implement so far . .. . Answer : What is the right way to shut down the Looper in an application with multiple activities and where Handlers created on this Looper have lifecycle different from ones of the activities .. . .. .

Comment : Are you suggesting to use Service for managing Looper s lifetime If so as I said before - I don t even know when to shut it down . In this case Service should be roughly equivalent to my static field . Alternatively if you are suggesting to use Service to do work on the non-main thread I am particularly interested in Handler s sending Message s to each other . Comment : With a service you not have to deal with Looper s lifetime . You can just bind it to Service lifetime and let the System to manage it .

I suggest you read the Activity and Service articles in the Api guides and then read Handler and Looper . It also helps if you have an understanding of what a thread is not an android thread but a thread in general...e.g . POSIX . .. . Answer : A Looper has a synchronized MessageQueue that s used to process Messages placed on the queue . It implements a Thread Specific Storage Pattern . Only one Looper Thread Key methods include prepare loop and quit . prepare initializes the current Thread as a Looper . Prepare is static method that uses the ThreadLocal class as shown below . prepare must be called explicitly before running the event-loop . loop runs the event-loop which waits for Messages to arrive on a specific Thread s messagequeue . Once the next Message is received the loop method dispatches the Message to its target handler quit shuts down the event-loop . It doesn t terminate the loop but instead it enqueues a special message .. . .. . A Looper can be programmed in a Thread via several steps", "Question : I am trying to implement Handlers listening on the same Looper from different threads . Below I have two Handlers one created in the main thread another in the child thread however both are initialized to listen on the Main Looper . But when I send a message like below only the child handler prints the message . The main handler does not receive the message . What am I doing wrong Thank you for reading . .. . Answer : Each Handler instance controls the Message target and there is no way to get them to share so every message or post sent to a Handler is only executed by that instance . The Looper indicates which thread the messages runnables sent will be executed on . In your code both Handlers will execute handleMessage on the main thread despite being created on separate threads . That is the real reason you can pass a Looper instance to a Handler ...if you pass no Looper then the Handler will execute code on the thread in which it was created which must also be a Looper thread . Furthermore because of this there isn t reason to create multiple Handlers to post data in this manner . A single Handler is designed to be sent messages from multiple threads and they are all serialized in a MessageQueue and executed on the chosen Looper thread . You can post directly to mMain from the background-thread to execute code on that thread . In this case passing the Looper is redundant at that code is already on the main thread . Comment : I see thanks Suppose if one day the Runnable was an outer class instead of an inner class I should pass an initialized Handler to it via its constructor right Comment : The architecture would be application dependent but you would need a reference to the Handler from wherever you plan to post messages to it . Comment : Why not just use one Handler this.getMainLooper in the Application context the class that extends Application Wouldn t this be cleaner than doing it in an Activity", "Question : I have checked the official Android documentation guide for Looper Handler and MessageQueue . But I couldn t get it . I am new to android and got very confused with these concepts . .. . Answer : It s widely known that it s illegal to update UI components directly from threads other than main thread in android . This android document Handling Expensive Operations in the UI Thread http : developer.android.com guide faq commontasks.html threading suggests the steps to follow if we need to start a separate thread to do some expensive work and update UI after it s done . The idea is to create a Handler http : developer.android.com reference android os Handler.html object associated with main thread and post a Runnable http : developer.android.com reference java lang Runnable.html to it at appropriate time . This Runnable will be invoked on the main thread . This mechanism is implemented with Looper http : developer.android.com reference android os Looper.html and Handler http : developer.android.com reference android os Handler.html classes . The Looper class maintains a MessageQueue http : developer.android.com reference android os MessageQueue.html which contains a list messages http : developer.android.com reference android os Message.html . An important character of Looper is that it s associated with the thread within which the Looper is created . This association is kept forever and can t be broken nor changed . Also note that a thread can t be associated with more than one Looper . In order to guarantee this association Looper is stored in thread-local storage and it can t be created via its constructor directly . The only way to create it is to call prepare http : developer.android.com reference android os Looper.html prepare 28 29 static method on Looper . prepare method first examines ThreadLocal http : developer.android.com reference java lang ThreadLocal.html of current thread to make sure that there isn t already a Looper associated with the thread . After the examination a new Looper is created and saved in ThreadLocal . Having prepared the Looper we can call loop http : developer.android.com reference android os Looper.html loop 28 29 method on it to check for new messages and have Handler to deal with them . As the name indicates the Handler class is mainly responsible for handling adding removing dispatching messages of current thread s MessageQueue . A Handler instance is also bound to a thread . The binding between Handler and Thread is achieved via Looper and MessageQueue . A Handler is always bound to a Looper and subsequently bound to the thread associated with the Looper . Unlike Looper multiple Handler instances can be bound to the same thread . Whenever we call post http : developer.android.com reference android os Handler.html post 28java.lang.Runnable 29 or any methods alike on the Handler a new message is added to the associated MessageQueue . The target field of the message is set to current Handler instance . When the Looper received this message it invokes dispatchMessage http : developer.android.com reference android os Handler.html dispatchMessage 28android.os.Message 29 on message s target field so that the message routes back to to the Handler instance to be handled but on the correct thread . The relationships between Looper Handler and MessageQueue is shown below : .. . .. . enter image description here http : i.stack.imgur.com h4z38.jpg Comment : Thanks but whats the point if the handler first post the message to the message-queue and then handle the message from the same queue why doesn t it just handle the message directly Comment : @Blake b c you are posting from one thread non looper thread but handling the message in another thread looper thread", "Question : In this example from the documentation https : developer.android.com guide components services.html ExtendingService we use the looper of a thread and we use it in the Service class and then the Service will be working as-if it was in a separate thread Thanks .. . Answer : The thread a HandlerThread is started in onCreate when you call thread.start then you get a reference to the Looper of that thread only one Looper is created per HandlerThread to create a Handler and the Handler is used to post messages to the thread . The Looper is the object that waits for the messages in a while true loop . Every time a command is sent to the Service the Service posts a message to the HandlerThread through the Handler . A closer look at the source code will help you understand better how it all works . There s an excelente post about Handler s and Looper s at Square Engineering Blog - A journey on the Android Main Thread - Part 1 http : corner.squareup.com 2013 10 android-main-thread-1.html . You can also use an IntentService http : developer.android.com reference android app IntentService.html to avoid instantiating your own threads .

Thank you", "Question : I created a class extending Thread to retrieve user location through LocationManager in a non-ui thread . I implemented this as a thread because it has to be started on request and do its work just for a limited time . By the way I had to add a Looper object in the thread to be able to create the handler for the LocationManager onLocationChanged . This is the code : .. . .. . I would like the thread to start receive the user location data in this case just one time send the data to the main thread via a message to the handler and then die . The problem is that in my case the thread does not die anymore once the run method ended that should be fine because otherwise onLocationChanged would not receive the new locations . But in this way assuming that thread s stop and suspend methods are deprecated what would be a good way in this case at least to make a thread with a looper die Thanks in advance .. . Answer : You can explicitly quit from Looper s loop using Handler : Comment : In my case handler is a Handler object passed to this thread from the calling thread to be used to pass the collected data from one to another . Thus I cannot call handler.getLooper .quit because it refers to the activity thread and not to the userLocationThread . Note that onLocationChanged is inside the new thread and that Looper is required to let this callback method to be called when the locationManager receives a location . Comment : When you call Looper.myLooper you get Looper associated with current thread . When you call handler.getLooper you get Looper associated with specific handler . Comment : But if the handler is associated with the same thread the returned Looper should be the same doesn t it Comment : Yes if you create handler in the same thread where you call Looper.myLooper they should be the same . Comment : Oh I see what you mean : No in your original code you call Looper.myLooper .quit after you call Looper.mylooper .loop . The loop function does not return unless you call quit . And you call quit after loop . So basically you never reach your quit and end up in infinite-loop :" ] }

ListPicker as an ItemsControl gets its Items property set to a list of ListPickerItems in your example . ListPickerItems are UIElements and the ListPicker renders them in its presenter . When there are 5 or less items the expanded mode opens on the current page and you can see all the items in the presenter . .. . But when 6 or more items are present opening the list picker goes to full mode which opens a new page . This new page has a listbox which gets its items property set to the listpicker s items . This is where it breaks . By setting the listbox s items to the listpicker s items in this case a list of listpickeritems the listbox will put those UIElements into its view . Now a single listboxitem is included in two places on the visual tree . .. . Because of this issue ListPicker only supports databinding and templating .

What am I doing wrong here I want to remove one objectClass from a given entry using python-ldap . Comment : Generally you can t change object classes on existing objects because that would invalidate any schema checks the server did when creating the object . You ll have to delete the object and create a new one . This is a property of the server and doesn t have much to do with the client library . Comment : @Guntram Blohm Great answer and I figured out the same by experimenting . Can you post it as an answer so that I can go ahead and mark it as the answer to the problem .. . Answer : As stated by Guntram Blohm it is not possible to delete object classes on existing objects because doing that would invalidate the schema checks that the server did when creating the object . So the way to do it will be to delete the object and create a new one .

This article http : www.perrygeo.com running-python-with-compiled-code-on-aws-lambda.html - even though unrelated to the python-ldap module - describes how to bundle Python packages that have native dependencies . The outline of this is the following : .. . .. . Create an Amazon EC2 instance with Amazon Linux .. . Install compiler packages as well as the OpenLDAP developer package . yum install -y gcc openldap-devel .. . Create a virtual environment : virtualenv env .. . Activate the virtual environment : env bin activate .. . Upgrade pip I am not sure this is necessary but I got a warning without this : pip install --upgrade pip .. . Install python-ldap : pip install python-ldap .. . Create a handler Python script for example lambda.py with the following code : .. . .. . .. . import os .. . import subprocess .. . .. . libdir os.path.join os.getcwd local lib .. . .. . def handler event context : .. . command LD LIBRARY PATH python ldap.py .format libdir .. . subprocess.call command shell True .. . .. .

Answer : The at the end is often an indicator that it is Base64 https : en.wikipedia.org wiki Base64 encoding . Python has a standard-library for encoding decoding base64 https : docs.python.org 3 library base64.html The link is for Python 3 but Python 2 also has the library . LDAP does indeed use Base64 for something . See The LDAP Data Interchange Format LDIF https : tools.ietf.org html rfc2849 . Comment : Thanks for the reply . There seems to be something weird with the encoding for example if I modify the mobile attribute and set it to Hello World it is stored in AD as : mobile : : 77+9ehsCAAAAABDvv70V That doesn t decode to anything in Base64 other than gibberish . If I am using OpenLDAP from the command-line I can create an .ldif file to modify that attribute and it will show up correctly so I am not sure if this is something specifically tied to python-LDAP and AD Comment : I also saw that the double colon s in the LDAP Search result signify the item in Base64 encoded though if I modify the attribute via an LDIF file the attribute does not get encoded it only seems to behave this way when I am trying to modify attributes via python rather than using openLDAP commands.. .", "Question : I ve been trying to use Python-LDAP http : www.python-ldap.org version 2.4.19 under MacOS X 10.9.5 and Python 2.7.9 .. . .. .

As shown I have two files which represent a bad certificate and one which should work it s actually taken from one of our systems which is configured to run sssd https : fedorahosted.org sssd System Security Services Daemon which is presumed to be checking this correctly . In the bad copy I ve simply replaced the first character of each key line with the letter x on the assumption that this would corrupt the CA key and cause any code attempting to verify a chain of signatures to fail . However it seems that the Python LDAP code ignores this even if I set it to dev-null or an entirely bogus path my code still runs still binds to the LDAP server and still completes my search request . So the question is how do I get this to fail as intended or more broadly how do I prevent my code from being vulnerable to MITM Mallory attacks If it s of any consequence in this discussion here s my OpenSSL version : .. . .. . The LDAP server is running OpenLDAP but I don t know any details about its version nor configuration . Here s sample output from my code : Comment : I d also like to check for a CRL but that s a different matter - be careful with this . You could be setting yourself up for a DoS due to missing broken CRLs and OCSP responders . Mozilla turned it off for a while because it had such a negative effect on the user-experience . Stapled responses would probably be the way to go . Comment : In my case this will be working in an environment that provides their own CA and manages their own CRLs . It s all internal . Comment : I might be the bearer of bad news.. . Python-LDAP can use OpenSSL . But the calls one typically utilizes or encounters for certificate handling are not present . For example I get 0 hits for cd python-ldap grep -R -i ca certs grep -R -i wrap socket grep -R -i certs reqs . You might want to reach out to the developers to see their position . They may say something like the code is meant to be run in the same security boundary as the ldap server . So we use a certificate for confidentiality but we don t verify the server or employ server authentication because there s no active MitM . Comment : According to their web page Python-LDAP wraps OpenLDAP and not OpenSSL directly . As far as I remember the OpenLDAP client library can be configured via environment-variables so I d expect this feature to work even if Python-LDAP has no specific provisions for it or even if they exist but do not work . How you get the error message back is an interesting part but it should not continue with the connection .

Answer : ImageMagick a command-line utility and programming library must be installed on the system for Imagick to work . If it s not working for you then presumably Heroku s PHP web dynos do not have this installed by default . You have two options : you can find some convoluted way to package ImageMagick with your application itself for instance by adding compiled binaries to your git source tree . Or you can modify the Heroku PHP buildpack https : github.com heroku heroku-buildpack-php which is the set of rules that sets up the web dyno before your application is deployed to install ImageMagick along with Apache and PHP itself . The latter approach is more likely to work . Once you ve modified the buildpack change your application to point to your buildpack fork with the command-line Heroku tools the --buildpack option and redeploy .

Answer : After trying many solutions none seemed to work . I managed to install it on Windows 10 64-bit Apache 2.4 and PHP 5.6 but I think it should work for all versions . Hopefully you will have no problem installing Imagick for PHP . .. . .. . Step 1 Gather information .. . .. . First of all you should gather some information of your PHP environment . You can easily see your PHP information with the function phpinfo http : php.net manual en function.phpinfo.php .. . .. . The information you need : .. . .. . Architecture : x86 32-bit or x64 64-bit .. . PHP-version : you can find this in the header of the phpinfo http : php.net manual en function.phpinfo.php output . PHP Extension Build : This string contains 2 important parts : .. . NTS or TS .. . VCx like VC11 .. . Loaded Configuration File : the path to your used php.ini file . Step 2 Download Binary .. . .. . You can download the binary from the official site of ImageMagick http : www.imagemagick.org script binary-releases.php windows . I recommend you to read the small introduction under the Windows Binary Release to be certain which bits-per-pixel to choose from 8 or 16 . Downloading the latest version should be just fine . Make sure this binary is the same architecture as your PHP architecture that you have gathered in step 1 . Step 3 Install Binary .. . .. . Install the binary to your phpx.x.xx bin file . For example : C : wamp64 bin php php5.6.16 bin . This can be any folder but for the convenience I put in here .. . .. . Make sure Add application directory to your system path is checked . Should be checked by default though . Step 4 Download PHP extension .. . .. . The DLL PHP extension is available through the windows pecl php site http : windows.php.net downloads pecl releases imagick .. . .. . Again you can just click the latest version . Next of choose the right version based on the gathered information . For example : php imagick-3.4.1-5.6-nts-vc11-x64.zip .. . .. . This can be stripped into components : .. . .. . php imagick-3.4.1 - This is the php imagick extension with the version . This is not important . 5.6 - This is your PHP version and should be equal to the PHP-version you are using which you have determed in step 1 . NTS - This should be equal to the information of your PHP Extension Build that you have gathered in step 1 . VC11 - This should also be equal to the information of your PHP Extension Build that you have gathered in step 1 . x64 - This the architecture of the extension and should be equal to your PHP architecture that you have gathered in step 1 . Step 5 Extract PHP Extension .. . .. . After you have downloaded the file you should open the .zip file and look for a file named : php imagick.dll . Extract this file to phpx.x.xx ext . Make sure the .dll file is fully accessable by you . Sometimes you need to explicity unblock the file . Unblock file http : i.stack.imgur.com 7if55.png .. . .. . Step 6 Activate PHP extension .. . .. . To activate the extension in PHP you should state in your php.ini file that you want to use this extension . You have gathered the path to your used php.ini file in step 1 . Add the line extension php imagick.dll to your php.ini .. . .. . PHP.ini Imagick line http : i.stack.imgur.com aOJjG.png .. . .. . Step 7 Restart your PC .. . .. . Just to make sure restart your PC so all Environment Path s will be correctly loaded . .. . .. . This should install Imagick correctly with the latest versions and the right architecture . Imagick should also be listed in phpinfo http : php.net manual en function.phpinfo.php with the appropriate ImageMagick supported formats Just make sure it is not empty .", "Question : Steps I ve taken so far : .. . .. . 1 . I have installed Imagick on my Win7 machine and it s installed and running properly via command-line . 2 . I ve extracted the contents of php imagick-3.1.2-5.6-ts-vc11-x86.zip available here http : windows.php.net downloads pecl releases imagick 3.1.2 into my PHP ext directory . 3 . Enabled the imagick.dll in php.ini .. . 4 . Rebooted.. . .. . 5 . No errors when starting Apache . 6 .

I ve tried just about every write-up and walkthrough for installing Imagick for PHP on Windows but they seem to all be written for older versions of PHP . Can somebody help me get this installed and running It seems like it s just missing one simple step that I can t seem to figure out . If you need any more info please ask . I ll get you whatever I can to help . .. . Answer : Another solution that worked on 3 different windows installations 2 Windows 7 and 1 Windows 8.1 is to combine : .. . .. . ImageMagick-6.7.9-10-Q16-windows.exe with .. . .. . xampp-win32-1.8.3-5-VC11-installer.exe . Of course you will have to add the php imagick.dll to the php ext folder and also add extension php imagick.dll to php.ini . Restart apache after you do all of the above and if it complains about missing stuff restart your computer . Comment : Do note that you may have permission issues if installing ImageMagick in Program Files . The instructions I provided are synonymous with these . I tested with xampp wamp as well . Just match the x64 or x86 of ImageMagick and PECL extension versions with the architecture and version of PHP you installed . The main issue is that ImageMagick does not archive its binary releases . So it makes ImageMagick difficult to match up with past versions of PHP and the PECL extension .", "Question : I m trying to convert a RGB .gif to a CMYK .gif using IMagick PHP module .

This is a portion of an app for our sales people that allows them to customize a page with their contact information after they hit submit a PDF page is created which is then attached to the end of a larger document . The first page of the document is also dynamically created from the same form that they fill out . After they press submit 2 PDF files are created a front page and a back page then both pages are attached to a larger document creating a single report . Everything works great unless they enter Chinese characters then all I get is garbage characters like this - . The document still looks like this even before it is merged with the larger document . I have tried every possible scenario it seems from using a Unicode font to using my own created font and one by one trying each of the fonts in the TCPDF folder . I am at a total loss and have been for some time now . I feel like I have been on just about every website that mentions TCPDF .

I have ran the tt2fm and makefont to get the files but do not feel that those routines were a 100 successful . Please help - I have been working on this thing off and on for months . I am almost ready to just scrap it and hit the door . Thank you . Comment : Does the font need to be installed and changed .. . Answer : So html2pdf is based on tcpdf but they are a little bit different : html2pdf https : github.com spipu html2pdf does not support Chinese language . However you can get the javiergb.php from the include directory tcpdf fonts . Then you copy this file to the html2pdf tcpdf5.xxxx fonts directory .

Answer : The problem with trying to use a PDF as a template is that PDF is a typeset document format . Eg . it is a fixed layout and you shouldn t really mess with the layout too much . It would be much simpler if you want to do more with this to use something like XSL-FO to generate your documents from an XML template . All you need do is generate the XML with the right fields in-place and the XSL-FO renderer can then create the PDF for you . The best only free XSL-FO renderer is Apache FOP .", "Question : I m trying to use HTML2PDF 4.03 with this code : .. . .. . Now the program die with this : .. . .. .

This also still leaves part 2 issue open since I did enable CORS in the blob but I was not able using tools to change the http header Access-Control-Allow-Origin : in the blob . .. . Answer : One thing I noticed in all the screenshots is that for allowed origins you re trying to set the value as http : .attendedstorage.com . My guess is that it is causing problem . The URLs defined in allowed origins should be an exact match to the the actual URLs from which the cross-browser request is originating and this is case sensitive . From the documentation page http : msdn.microsoft.com en-us library dn535601.aspx : .. . .. . AllowedOrigins : The origin domains that are permitted to make a request against the storage service via CORS . The origin domain is the domain from which the request originates . Note that the origin must be an exact case-sensitive match with the origin that the user age sends to the service . You can also use the wildcard character to allow all origin domains to make requests via CORS . In the example above the domains http : www.contoso.com and http : www.fabrikam.com can make requests against the service using CORS . One thing you could try is by specifying the actual domain-name http : attendedstorage.com https : attendedstorage.com and see if that helps . If that doesn t work try by specifying i.e . all domain names are allowed to narrow down the issues . Comment : Thanks for responding Gaurav . Setting Access-Control-Allow-Origin : was one of the early things I tried but Cloudberry does not keep the setting no matter what I enter - I m able to enter and save it but then when I check back that header does not appear . Comment : Julie so you don t can t set this header explicitly . Also the CORS settings are applied on the entire blob storage account and not just one blob or container . When you set CORS settings you can use Cerebrata AMS this header will automatically be included in the response headers . The reason Cloudberry does not keep track of it is because Azure Blob Storage does not support this header on a blob . Only settable headers supported on the blobs are : content-type content-encoding content-language content-md5 and content-disposition . HTH . Comment : Yes I used Cerebrata to set CORS . So if Azure Blob Storage does not support Access-Control-Allow-Origin : does this mean that I cannot have the WebVTT track in an Azure Blob where I have the mp4 video Comment : Azure Blob Storage does support Access-Control-Allow-Origin : . Only thing is that you can t set it on a blob-by-blob basis its done at blob storage level . When you set CORS settings correctly this header is automatically added to the list of response headers . Comment : Within Cerebrata I ve tried both resetting CORS to the actual domain-name attendedstorage.com http : attendedstorage.com attendedstorage.com quot https : attendedstorage.com quot which did not make a difference and now to per cropme.ru c5c1129fc5301900bc75fabe3c44afc7 http : cropme.ru c5c1129fc5301900bc75fabe3c44afc7 - however unfortunately the WebVtt still gives errors within Chrome dev console and network as shown in dropbox.com s 8zhg95upfm9mbuk https : www.dropbox.com s 8zhg95upfm9mbuk Screenshot 202014-04-25 2009.47.52.png", "Question : I m looking to have a .vtt caption file play with a mp4 video per http : attendedstorage.com videotest2.html .. . .. .

Still I don t understand why this is needed in this scenario since the video and track originate from the same domain as the html files . This also still leaves part 2 issue open since I did enable CORS in the blob but I was not able using tools to change the http header Access-Control-Allow-Origin : in the blob . .. . Answer : Regarding to the parent of track element does not have a crossorigin attribute . issue it does not refer to azure blob storage but to the HTML file where you load the tracks . crossorigin is an attribute to set to the track tag parent for example video controls crossorigin anonymous . If you could solve the issue regarding to set the HTTP headers in azure adding the attribute crossorigin to your video or audio tag should solve the entire problem ." ] }

As long as the image url field has an UploadCare image url the widget works fine . But if it has something like : http : i.imgur.com foobar.jpg it says Incorrect value .

Is there some way to tweak this behavior Comment : How exactly do you want to tweak this behavior Widget can t show the arbitrary link as it s value : it don t know the real file name size and can t show preview .

Answer : I am trying to use the new .NET methods of sending email System.Net.Mail but I have various troubles along the way . My VB.NET app allows users to gather info and email it out based on the smtp server specs they set . Current issues are sending using STARTTLS i think thats what its called and doing things like authenticating via POP before being granted the ability to send . I have had great reliability using CDO to deliver mail in the past as a part of a vbscript I wrote and am going to look at integrating that over Net.Mail . Is there a problem with using CDO to deliver email over current .NET methods Is it deprecated or bad practice Is there any limitation based on current email technology Am I totally going to wrong direction and should instead use a precompiled SMTP Mail application I can drop in as part of my application I have seen people do this over writing their own code to deliver mail .

Until I find a scenario where CDO doesnt work I am going to use it . Comment : I could not deliver on port 465 when using Net.Mail . This is likely due to the fact that Verizon blocks outgoing connections on port 25 SMTP on consumer grade connections . Most of the people that use my application would be on Corp ISPs that would never block port 25 .

Comment : Hi @Kev I just installed IIS8.5 via Windows Features and .NET Framework 3.5 .. . Answer : When you use the cdoSendUsingPickup option you are simply writing the email message to a file which will be queued up for delivery asyncronously from your code . Yes this is dramatically faster as your code does not have to wait for the SMTP server to receive the message . So when using this option you do not need to specify the destination SMTP server the port the username password etc . Hopefully you are now asking yourself how does the server know where to send the message to if I don t specify a forwarding SMTP server . Well that s because you just have to configure the Microsoft SMTP Service to let it know what server to hand off the messages to .

Answer : The CreateMHTMLBody is not what you need . This method will create a multipart message fetching the URL and post processing the HTML returned . It fetches the resource for every img src it finds encodes the returned resource as a body part and updates the HTML img src to point at the body part . Also CreateMHTMLBody is not a good thing to use in ASP code since it uses the WinINET Http stack to fetch resources WinINET should not be used from ASP code . What you really need is to use something like WinHTTP to fetch the HTML resource and then assign that to the Message s HTMLBody property ." ] }

Comment : Same answer here : use faster processor by replacing uglifyJs with googleClosure", "Question : I am trying to setup my developer env so that I can use maven to compile my LESS files for formal builds but also have Eclipse compile the LESS for incremental builds so I dont have to keep kicking of maven tasks every time I make a LESS change . Having looked around - it seems like wro4j the maven-plugin the m2e-wtp plugin should provide all that . My setup is as follows : I have just installed the latest stable Eclipse Java EE package that includes the WTP stuff - v4.3 and I have installed the m2e plugin and the m2e-wtp plugins . pom.xml : .. . .. . wro.properties : .. . .. . wro.xml : .. . .. . Inside my less folder are basically a few css files that I have renamed .less files and one where I have actually added some LESS syntax with a few colour variables set . This mostly works as I make changes to my LESS the plugin detects and rebuilds my uber css file however rather critically it doesn t seem to be compiling the LESS - it combines the files and minifies but my @variables are all still in LESS syntax . I also noticed that the maven-plugin was up to v 1.7.0 so tried upgrading to that to see if that was the problem but that just does nothing at all nothing gets built at all and I have no uber css etc .. . .. . Anyone had any experience setting this up or know anything I have missed in the setup Comment : The v1.7.0 should work what exactly happens when you run maven-plugin from console There is an example project which can be used as a quick start project and can be forked to prove a bug : github.com wro4j wro4j-examples tree master wro4j-standalone https : github.com wro4j wro4j-examples tree master wro4j-standalone . Also I recommend using less4j processor instead of lessCss since it much faster . Comment : Thanks @AlexObjelean - If I run maven from the console it correctly builds and compiles the less files to CSS now I am using 1.7.0 but the eclipse incremental-build is still not working with this version like i mentioned using 1.4.5 the eclipse build was running it just didn t compile the LESS Comment : What maven version are you using The incremental-build feature is supported only by maven-3 or greater . Have you tried the v1.6.3 What happens You can open an issue and we can continue discussing there since SO should not be an issue tracker . Comment : I m noticing this behaviour too . I m using maven-3 . I get an eclipse incremental-build if I modify my pom.xml but if I change a less file nothing happens . Comment : I never made the full switch to 1.7 or above but the earlier version is now working ok for me - on the earlier version I was having problems with LESS not being compiled but failing silently - running a full maven build from command-line gave more verbose details of issues i saw . I have written up exactly what I had to do code on github on my blog here : automateddeveloper.blogspot.co.uk 2014 02 http : automateddeveloper.blogspot.co.uk 2014 02 eclipse-less-better-development-time.html .. . Answer : The problem was because I had some invalid LESS in one of my files - this basically meant the compile step was failing so the other LESS files were not being compiled to CSS which resulted in the LESS variables being output in my file - With the Eclipse incremental-build this failure was not being reported so I didn t see it . I discovered it by explicitly running the maven command and then got the normal maven logs which included details of the compilation failure . That aside the eclipse incremental-build for LESS is working really nicely since As mentioned in the comments above I wrote up how to set it all up here : .. . .. .

When using lessCSS instead of less4j the error reason is better shown : .. . .. . Changing the processor-order does not help : .. . .. . The error still exists . Is there a possibility to say wro4j that it should not treat files endings with css as less . Comment : Could you provide the content of the base.css file The exception is saying that toHSL function cannot be found . Where is it defined Comment : I have not any function in base.css . I have no toHSL -function in base.css . Base.css is only a pure css-file without any less-syntax . However the compiler of less is complaining about the following css-class : .img-saturate -webkit-filter : saturate 500 -moz-filter : saturate 500 -o-filter : saturate 500 -ms-filter : saturate 500 filter : saturate 500 . When deleting this css-class then all works fine . However I guess the problem lies in the fact that wro4j scanns and treats pure css-files also as less-files . The less-compiler should ignore files ending with .css . Comment : The less-compiler thinks that saturate is a less-defined function . However it is not . It s a css-function . Comment : By default a processor is applied to all resources . If you want less4j processor to be applied only to resourcess with less extension replace the less4j alias with less4j.less Comment : Actually it does matter . The file extension information is available for pre processors . When post processor is applied there is no extension info since a merged resources is processed . However if you want to apply less4j only to a certain resources or group you can customize it using something similar to code.google.com p wro4j wiki ProcessorDecorators http : code.google.com p wro4j wiki ProcessorDecorators .. . Answer : Thanks Alex .. . .. . by using less4j.less the less-processor will only scan less-files : .. . .. . However afterwards I found the real reason for the error . A ending brace was missing in the css file . By adding the brace all works fine", "Question : null .. . Answer : So I have a pretty big application with a lot of imports . Third party js libraries and a lot of angular code . Now I glued them all together with wro4j into two big files that are compressed . The order in which I did it is correct as the application works as intended . But often times when I press F5 to reload the page stuff will break . JS console will start throwing errors and some style settings get lost on the page . But at the same time when I look at the source code everything is still there . Angular tells about missing modules that are all there and the css that is broken.. . well the correct css is also in one file and correctly loaded into the page source code . Has anyone experienced something like this How would you debug this Comment : Could you create a quick-start project which would help to reproduce the problem Comment : Dont think so . Its a job project where I am trying to use wro4j in . We have like over 150 javascript files atleast that need to be compressed . Problem is that wro4j randomly does not included some files from time to time . It can be a css file or a js file . And the files that dont get included are completely random every time .

I need to work this with spring-mvc : resources . Now if do the configuration its failing to load the resources .

But wro is a logical location configured based on WRO4J requirement . There is any way to map the mvc : resources to map the logical location like this . If you guys have any thoughts please share here . Thank u so much -Geek- .. . Answer : The default mapping used by wro4j wro is not a requirement . You can map the WroFilter to any suitable location example : .js or .css . When it is mapped to something like .js it will handle all requests having js extension and in case it cannot handle it the filter will chain the request processing .

I have everything setup but I m getting a JSMin UnterminatedStringLiteralException when the minifier attempts to compress the OpenLayers.js file I m using . So I figured it would be worth the time to configure wro4j to use a different js minification tool . After reading through the documentation on the wro4j wiki I added the core and extension jar to my project . The problem is that neither jar contains the class file for the YUIJsCompressorProcessor despite the documentation indicating otherwise https : code.google.com p wro4j wiki AvailableProcessors . So I need to know whether or not there is something I overlooked . .. . Answer : The YUIJsCompressorProcessor was deprecated and removed since version 1.6.0 because the library is not developed anymore and uses an older version of rhino which is not compatible with other processors requiring newer version of rhino . As an alternative you can use GoogleClosureCompressorProcessor UglifyJsProcessor or PackerJsProcessor .", "Question : Editing the original question to provide all the details .

I have not installed the m2e-wro4j plugin in my eclipse IDE .

To make sure that that wro.properties file is correctly placed and is picked up by the plugin I tried some wrong values in this file postProcessors less4jtttt and could see an exception while doing the build . However an invalid file path in wro.xml file did not throw any execption . Please suggest . Regards . Comment : Could you provide the output created when running the plugin Also could you try to upgrade the wro4j version to 1.7.3 and use the less4j much faster processor instead of lessCss which is based on rhino and is quite slow . Beside that the wro.xml should contain the group definitions which are missing from issue description . Comment : Hi Alex I have modified the original post with all details . Please help Comment : I don t think stackoverflow is appropriate for providing this kind of support . If you want we can discuss this issue either on wro4j mailing list or on a dedicated issue . What puzzles me is that you are using both : runtime and build-time solution in the same time.. . Also you specify two different wro4j versions in your pom.xml . Another problem is that you are using less4j processor as both : pre post processor . Another thing is : the console output is incomplete. . it doesn t the final completion results of the maven-plugin . Comment : Hi Alex I tried a few other ways : i removed less4j from the pre-processor list . I also removed the filters from web.xml and I also removed all the entries from pom.xml except the wro4j-maven-plugin entry . However I could still not see the CSS getting generated .

Its job is to generate and prepend SASS vars to a group of SASS files which are then handed off to the rubySassCss filter for transpiling and it s doing this job well . The problem is that I wanted to hand the job of determining the SASS vars off to a custom ThemeManager @Service managed by Spring . I hadn t considered that the filter wouldn t be able to see the autowired @Service but that seems to be the case . When I @Autowire the @Service into a controller it works fine but when I try the same thing with the filter I get a NPE when attempting to use it . Is there a way to make the @Service visible to the filters or am I approaching this the wrong way Thanks for any help . UPDATE : .. . .. . It s taken some doing and attacking from a lot of angles but I seem to be having success with autowiring my themeManagerService into the app configuration where I have my WRO filterRegistrationBean bean . I then pass the themeManagerService bean as a second argument to my custom ConfigurableWroManagerFactory . Living in the custom WroManagerFactory is a reference to a custom UriLocator which takes that themeManagerService as an argument . The custom UriLocator is invoked by a CSS resource containing an arbitrary keyword within a group . The new UriLocator is able to generate a ByteArrayInputStream from what the themeManagerService provides it and pass it into the pipeline . Simple . I ll follow up when this approach pans fizzles out . .. . Answer : In the end I was able to provide the spring managed ThemeManagerService directly to the custom post processor rather than relying on a custom UriLocator . I had tried that early on but forgot to call super in the new constructor so the processor registration system was breaking . I pass the @Autowired ThemeManagerService to my CustomConfigurableWroManagerFactory when registering the WRO bean : .. . .. . The constructor-injection of ThemeManagerService into CustomConfigurableWroManagerFactory means it can be passed along to the custom postprocessor as it s registered by contributePostProcessors : .. . .. .

I checked the source code of xsbt-wro4j-plugin here https : github.com BowlingX xsbt-wro4j-plugin blob master src main scala com bowlingx sbt plugins wro4j Processors.scala and also the wro4j API documentation to gain some insight into the file creating process but I m a bit puzzled here . As far as I can tell the plugin uses Mockito to produce the necessary resources somehow but I don t get how it cooperates with wro4j itself . If I m right this whole Mockito stuff is a hack so we can use SBT s caching mechanism . Question 1 is whether we can avoid this Mockito voodoo without losing caching support . Question 2 : what is responsible for file creation within wro4j Could I override it .. . Answer : This is not necessarily an answer for all of your questions but an explanation for the reason xsbt wro4j plugin and wro4j-maven-plugin uses mockito . The wro4j was created initially as a runtime solution only using HttpServletFilter to minimize static resources on the fly . As result the internal API is based on servlet-api more specifically HttpServletRequest HttpServletResponse objects . Later when a build-time solution was required instead of changing the internals of the framework a suitable workaround was applied : using a mechanism for stubbing servlet-api in a non servlet environment build-time . The way I see the long term approach : is to make wro4j servlet-api agnostic and allow build-time solutions like maven-plugin or xsbt plugin to not require using this workaround . Unfortunately in order to do that the internals of the wro4j should be changed and that would require a major release incompatible with previous versions . Given the amount of work required to do that most probably this will be delayed . Comment : Ah this does make sense .

Answer : Php editors don t evaluate PHP code like HTML those only allow to edit code with cute formatting and useful features . For running PHP code you need web server like apache or nginx .", "Question : I have used PHPEd for several years as my IDE of choice . It is fantastic and fast but still doesn t have native support for git . I need to use git and I want it integrated into my workflow . I have heard great things about Aptana - including that it has great git integration so have installed it and I am now trying to get my head around all the differences . 1 . What is with the workspace being linked to a folder In PHPEd the workspace is simply a collection of projects . It s not tied to a location in the filesystem apart from where the .ppw file which stores the workspace meta information is stored . 2 . Similarly why are projects tied to a particular folder In PHPEd a project is not tied to a particular location in the filesystem . Yes the project has a root folder defined but it s simply a property of the project . This means there are no project related files metafiles cluttering the filestructure of the project source files . Can Aptana be made to behave in this way 3 . Connections - The connections are similar but the way projects reference them is not . In PHPEd I have a connection for each remote-server I use . Then in a project I can specify a remote root folder relative to the connection - this allows me to have one connection used by multiple-projects if they are all published on the same remote-server . Can Aptana behave like this Or do I have to define a separate connection for each project 4 . What is the best way to create a project from an existing source I like my local file structure to mirror the filestructure on my host machine . This allows for easy moving of folders easy synchronisation allows me to syncronise browsing in Filezilla etc . So my work directory will look something like this : .. . .. . www .. . dev html .. . development - this is the root of a development subdomain .. . test - this is the root of the last build being tested in the test subdomain .. . intra html - contains the root folders of various intranet subdomains .. . crm .. . kb .. . public html - this is the live site .. . .. . .. . Now I really don t want to point Aptana at these folders and have it add it s metafolders but I don t want to have Aptana replicate these folders - introducing another shard . How can I create projects that point to these existing files I know this is related to my second question but is there a way to have Aptana keep these local files up-to-date if it has to replicate them locally 5 . What is the best way to integrate with git if I want to be able to easily upload to the remote host PHPEd handled this with a simple keyboard shortcut - Ctrl+Shift+S - which would upload to the remote-server immediately but there was no support for git . I have a remote repository bitbucket which is separate from my remote host . I was hoping git integration would make it easy to have both immediate upload to my development-environment as well as the ability to easily commit once everything is working as I want . Part of my issue is that the terminology in Aptana is not really intuitive to me coming from PHPEd and is not very well explained . If I want to add a framework folder for code autocompletion is that an External Directory under the PHP Buildpath tab And what is the PHP buildpath In summary I want to have a local file structure that mirrors the hosting file structure I want to be able to very easily syncronise local files to the host and I want to be able to easily stage and then commit those files I haveedited once I have tested them on the host . Is all this possible with Aptana Or do I need to go through the massive pain of integrating git with PHPEd .. . Answer : Try tortoise git you will have the same kind of integration like you had with tortoise svn . And you cannot use PHPEd s debugger with Aptana I have used both Xdebug PHPEd s debugger and I can tell you that Xdebug is crap compared to PHPEd . I don t work for NuSphere but they have absolutely the best PHP debugger . Comment : I ve accepted this as this is the route I ended up finding and going with . I have now ditched Aptana and stuck with PhpED - nothing comes close I am afraid . Comment : If you found yourself spending hours trying to get a decent debugging experience you ll find PHPEd a breeze . For me it s the no 1 reason to stick with it . Maybe there are others offering the same thing but I haven t encountered them yet . Comment : Nothing beats PHPEd s debugger .

If I am using Samba to map the Linux drive to Windows then will Git not be required on Windows Comment : @user1032531 it would still be required if you want to add commit revert merge or do any of the git commands in the repo you would access through the share .

Comment : The Local Development Centos Server is located in my house and is on a high speed LAN . If I have the code on my Windows PC I would need to keep it synchronized . Why not make it one drive shared by both Comment : @user1032531 Because in that case you simply don t need git . If you are using git for versioning and branching then you clone a repo you don t access through the network however fast it is : Git has been designed to be fast on the local drive not on the LAN WAN .

As soon as I type the at the end of it I get the little yellow box showing something like this : .. . .. . with the first argument bold . If I type it and then a comma it bolds the second arg and so on . This is really nice since PHP functions are a bit scrambled as far as argument order and I don t have to look them up every time . How it works now : .. . .. . I type a php function say strpos . As soon as I type the at the end of it I get the little yellow box . It says something like strpos - Returns the numeric position of the first occurrence of needle in the haystack string . There are no arguments shown which makes the little box basically worthless - I know what strpos does I just want a reminder of the argument order .

Again though I have no problem doing the calculation just need help making the syntax acceptable . Comment : To implement your own equality such as vector boolean you will have to define special values objects TRUE and FALSE because it is unable to use eq metamethod for comparing two different types .

I want to be able to do something like a b+5 c d where a b c and d are all vectors arrays . Rewriting that as prefix function-calls is very verbose : less than divide multiply a add b 5 c d . I can t ask my users to write that . .. . Answer : You only have two choices to make this work with your syntax : .. . .. . Option 1 : Patch the Lua core . .. . .. . This is probably going to be very difficult and it ll be a maintenance nightmare in the future . The biggest issue is that Lua assumes on a very low-level that the comparison operators return a bool value . The byte-code that Lua generates actually does a jump on any comparison . For example something like c 4 5 gets compiled to byte-code that looks much more like if 4 5 then c true else c false end . You can see what the byte-code looks like with luac -l file.lua . If you compare the byte-code of c 4 5 with c 4+5 you ll see what I mean . The addition code is shorter and simpler . Lua assumes you ll do branching with comparisons not assignment . Option 2 : Parse your code change it and run that .. . .. . This is what I think you should do . It would be very hard expect most of the work is already done for you using something like LuaMinify https : github.com stravant LuaMinify . First of all write a function you can use for comparisons of anything . The idea here is to do your special comparison if it s a table but fall back on using for everything else . Now all we need to do is replace every less than operator a b with my less a b . Let s use the parser from LuaMinify https : github.com stravant LuaMinify . We ll call it with the following code : .. . .. . All this will do is parse the code into a syntax tree and then spit it back out again . We ll change FormatIdentity.lua to make it do the substitution . Replace the section near line 138 with the following code : .. . .. . That s all there is to it . It will replace something like c a b c+d with my less a b c+d . Just shove all your code through at runtime . Comment : Thanks I will give your code a try and see how it works . I like the idea since it leaves me with the syntax I want which is very important ." ] }
