How can I modify .xfdl files?

The .XFDL file extension identifies XFDL Formatted Document files. These belong to the XML-based document and template formatting standard. This format is exactly like the XML file format however, contains a level of encryption for use in secure communications. I know how to view XFDL files using a file viewer I found <a href = "http://www.e-publishing.af.mil/viewerdownload.asp">here</a>. I'd like, however, to modify these files on the fly. Any suggestions?

What good Podcasts are out there?

Yes, Podcasts, those nice little Audiobooks I can listen to on the way to work. With the current amount of Podcasts, it's like searching a needle in a haystack, except that the haystack happens to be the internet and is filled with too many of these "Hot new Gadgets" stuff :( Now, even though **I** am mainly a .net Developer nowadays, maybe anyone knows some good Podcasts from people regarding the whole software lifecycle? Unit Testing, Continous Integration, Documentation, Deployment... Currently, the only two Podcasts i subscribe to are [StackOverflow][1] and [Hanselminutes][2], but [.net Rocks!][3] also sounds interesting. So - what are you guys listening to?

How do I calculate these statistics?

I'm writing an app to help facilitate some research, and part of this involves doing some statistical calculations. Right now, the researchers are using a program called SPSS. Part of the output that they care about looks like this:  They're really only concerned about the 'F' and 'Sig.' values. My problem is that I have no background in stats, and I can't figure out what the tests are called, or how to calculate them. I thought the 'F' value might be the result of the [F-test](http://en.wikipedia.org/wiki/F-test#Table_on_F-test), but after following the steps given on Wikipedia, I got a result that was different from what SPSS gives.

ASP.NET built in user profile, Vs old stile user class/tables

I am looking for the spiritual guidance of what is the best practice around the use of Profile feature in ASP.NET. How do you decide what should be kept in the built in user Profile, or if you should just go and create your own DB Table and add a column for that? For example, a user has a zip code, should I save the zip code in my own table, or should I add it to the web.config xml profile and then access it via the user profile ASP.NEt mechanize? The pros/cons I can think of are that since I don't know the profile so well, (it is a bit of a *Matrix* right now) I probably can do whatever I want if I go the table route (like, SQL to get all the users in the same zip code as the current user), I don't know ifI can do the same if I use the ASP.NET profile.

Any online resources for learning Lingo/Shockwave Director?

I've been doing bits and pieces of work in Lingo while helping a friend with some projects he's working on, but I haven't found any good resources for actually learning the language. I'm sure I could pick up an old book somewhere that explains it, but I really just want a quick lesson and I think a website with some sample code and function reference would be perfect. Does this exist? My experience searching for lingo documentation in the past leads me to believe that it's just not on the web anywhere.

How to pass enumerated values to a web service

My dilemma is, basically, how to share an enumeration between two applications. The users upload documents through a front-end application that is on the web. This application calls a web service of the back-end application and passes the document to it. The back-end app saves the document and inserts a row in the *Document* table. The document type (7 possible document types: *Invoice*, *Contract* etc.) is passed as a parameter to the web service's *UploadDocument* method. The question is, what should the type (and possible values) of this parameter be? Since you need to hardcode these values in both applications, I think it is O.K. to use a descriptive string (*Invoice*, *Contract*, *WorkOrder*, *SignedWorkOrder*). Is it maybe a better approach to create a *DocumentTypes* enumeration in the first application, and to reproduce it also in the second application, and then pass the corresponding integer value to the web service between them?

I'm currently using XML in a Python project for structured content created by hand in a text editor, and I was wondering what the general opinion was on Protocol Buffers as a user-facing input format. The speed and brevity benefits definitely seem to be there, but there are so many factors when it comes to actually generating and processing the data.

OK. This is a bit of a vanity app, but I had a situation today at work where I was in a training class and the machine was set to lock every 10 minutes. Well, if the trainers got excited about talking - as opposed to changing slides - the machine would lock up. I'd like to write a teeny app that has nothing but a taskbar icon that does nothing but move the mouse by 1 pixel every 4 minutes. I can do that in 3 ways with Delphi (my strong language) but I'm moving to C# for work and I'd like to know the path of least resistance there.

Triple Quotes? How do I delimit a databound Javascript string parameter in ASP.NET?

How do I delimit a Javascript databound string parameter in an anchor OnClick event? I have an anchor tag in an ASP.NET Repeater control. The OnClick event of the anchor contains a call to a Javascript function. The Javascript funciton takes a string for it's input parameter. The string parameter is populated with a databound value from the Repeater. I need the 'double quotes' for the Container.DataItem. I need the 'single quotes' for the OnClick. And I still need *one more delimiter* (triple quotes?) for the input string parameter of the Javascript function call. Since I can't use 'single quotes' again, how do I ensure the Javascript function knows the input parameter is a string and not an integer? Without the extra quotes around the input string parameter, the Javascript function thinks I'm passing in an integer. Cheers in advance for any knowledge you can drop. The anchor: <a id="aShowHide" onclick='ToggleDisplay(<%# DataBinder.Eval(Container.DataItem, "JobCode") %>);' >Show/Hide</a> and here is the Javascript: <script language="JavaScript" type="text/javascript"> /* Shows/Hides the Jobs Div */ function ToggleDisplay(jobCode) { /* Each div has it's ID set dynamically ('d' plus the JobCode) */ var elem = document.getElementById('d' + jobCode); if (elem) { if (elem.style.display != 'block') { elem.style.display = 'block'; elem.style.visibility = 'visible'; } else { elem.style.display = 'none'; elem.style.visibility = 'hidden'; } } } </script>

Mapping latitude/longitude to a distorted map

I have a bunch of latitude/longitude pairs that map to known x/y coordinates on a (geographically distorted) map. Then I have one more latitude/longitude pair. I want to plot it on the map as best is possible. How do I go about doing this? At first I decided to create a system of linear equations for the three nearest lat/long points and compute a transformation from these, but this doesn't work well at all. Since that's a linear system, I can't use more nearby points either. You can't assume North is up: all you have is the existing lat/long->x/y mappings.

Since that's a linear system, I can't use more nearby points either. You can't assume North is up: all you have is the existing lat/long->x/y mappings.

How to RedirectToAction in ASP.NET MVC (Preview 4) without losing request data

Using ASP.NET MVC (Preview 4) there are situations (such as form submission) that may require a RedirectToAction. One such situation is when you encounter validation errors after a form submission and need to redirect back to the form, but would like the URL to reflect the URL of the form, not the action page it submits to. As I require the form to contain the originally POSTed data, for user convenience, as well as validation purposes, how can I pass the data through the RedirectToAction()? If I use the viewData parameter, my POST parameters will be changed to GET parameters. ## Heading ##

How many DataContexts are appropriate?

In order to fully use LinqToSql in an ASP.net 3.5 application, it is necessary to create [DataContext][1] [classes][2] (which is usually done using the designer in VS 2008). From the UI perspective, the DataContext is a design of the sections of your database that you would like to expose to through LinqToSql and is integral in setting up the ORM features of LinqToSql. My question is: I am setting up a project that uses a large database where all tables are interconnected in some way through Foreign Keys. My first inclination is to make one huge DataContext class that models the entire datbase. That way I could in theory (though I don't know if this would be needed in practice) use the Foreign Key connections that are generated through LinqToSql to easily go between related objects in my code, insert related objects, etc. However, after giving it some thought, I am now thinking that it may make more sense to create multiple DataContext classes, each one relating to a specific namespace or logical interrelated section within my database. My main concern is that instantiating and disposing one huge DataContext class all the time for individual operations that relate to specific areas of the Database would be impose an unnecessary imposition on application resources. Additionally, it is easier to create and manage smaller DataContext files than one big one. The thing that I would lose is that there would be some distant sections of the database that would not be navigable through LinqToSql (even though a chain of relationships connects them in the actual database). Additionally, there would be some table classes that would exist in more than one DataContext. Any thoughts or experience on whether multiple DataContexts (corresponding to DB namespaces) are appropriate in place of (or in addition to) one very large DataContext class (corresponding to the whole DB)?

CPU throttling in C++

I was just wandering if there is an elegant way to set the maximum CPU load for a particular thread doing intensive calculations. Right now I have located the most time consuming loop in the thread (it does only compression) and use GetTickCount() and Sleep() with hardcoded values. It makes sure that the loop continues for a certain period of time and than sleeps for a certain minimal time. It more or less does the job i.e. guarantees that the thread will not use more than 50% of CPU. However behavior is dependent on the number of CPU cores (huge disadvantage) and simply ugly (smaller disadvantage :)). Any ideas?

How far can LISP macros go?

I have read a lot that LISP can redefine syntax on the fly, presumably with macros. I am curious how far does this actually go? Can you redefine the language structure so much that it borderline becomes a compiler for another language? For example, could you change the functional nature of LISP into a more object oriented syntax and semantics, maybe say having syntax closer to something like Ruby? Especially, is it possible to get rid of the parenthesis hell using macros? I have learned enough (Emacs-)LISP to customize Emacs with my own micro-features, but I am very curious how far macros can go in customizing the language.

Most Efficient Way to Test Object Type

I have values stored as strings in a DataTable where each value could really represent an int, double, or string (they were all converted to strings during an import process from an external data source). I need to test and see what type each value really is. What is more efficient for the application (or is there no practical difference)? 1. Try to convert to int (and then double). If conversion works, the return true. If an exception is thrown, return false. 2. Regular expressions designed to match the pattern of an int or double 3. Some other method?

So a windows exe file has access to the command string which invoked it, including its path and filename. eg. "C:\MyApp\MyApp.exe --help". But this is not so for a dll invoked via LoadLibrary.

Can you recommend a good CSS online resource or book?

Are there any favorite online references or good introductory and intermediate/advanced books on this topic that you'd recommend? The backstory is that I'm working on a web development project that is "re-skinning" our existing web site to make it more usable and visually appealing given current technologies that either weren't available or widely adopted as the site evolved (over the last ten-plus years). Of the new technologies and methods, CSS, although not really all that new, is the most interesting to me because it is clear that it has great power beyond simple styling of fonts and colors - and, as the saying goes, "With great power comes great responsibility." In other words, it is (now) clear to me that CSS is more than a way to apply a look and feel to page markup but is a way to *apply behaviors* to web pages. So it seems to me that it will be required to understand at a fundamental level "how CSS works" not so much from a page designer's perspective but from that of a programmer or software engineer in order to find and correct "bugs" in the behaviors of a given web page. So, I'm looking for a place to start...

Convert HashBytes to VarChar

I want to get the MD5 Hash of a string value in SQL Server 2005, I do this with the following command: SELECT HashBytes('MD5', 'HelloWorld') However, this returns a VarBinary instead of a VarChar value. If I attempt to convert "0x68E109F0F40CA72A15E05CC22786F8E6" into a VarChar I get "há ðô§*à\Â'†øæ" instead of "68E109F0F40CA72A15E05CC22786F8E6". Is there any SQL based solution?

How do I define custom web.config sections with potential child elements and attributes for the properties?

The web applications I develop often require co-dependant configuration settings and there are also settings that have to change as we move between each of our environments. All our settings are currently simple key value pairs but it would be useful to create custom config sections so that it is obvious when two values need to change together or when the settings need to change for an environment. What's the best way to create custom config sections and are there any special considerations to make when retrieving the values?

Easy way to AJAX WebControls

I've got an web application that I'm trying to optimise. Some of the controls are hidden in dialog-style DIVs, so I'd like to have them load in via AJAX only when the user wants to see them. This is fine for controls that are mostly Literal-based (various menus and widgets), but when I have what I call "dirty" controls - ones that write extensive information to the ViewState, put tons of CSS or script on the page, require lots of references etc - these are seemingly impossible to move "out of page", especially considering how ASP.NET will react on postback. I was considering some kind of step where I override Render, find markers for the bits I want to move out and put AJAX placeholders in there, but not only does the server overhead seem extreme, it also feels like a complete hack. Besides, the key element here is the dialog boxes that contain forms with validation controls on them, and I can't imagine how I would move the controls _and_ their required scripts. In my fevered imagination, I want to do this: AJAXifier.AJAXify(ctlEditForm); Sadly, I know this is a dream. How close can I really get to quick-and-easy AJAXification without causing too much load on the server?

Mapping Stream data to data structures in C#

Is there a way of mapping data collected on a stream or array to a data structure or vice-versa? In C++ this would simply be a matter of casting a pointer to the stream as a data type I want to use (or vice-versa for the reverse) eg: in C++ Mystruct * pMyStrct = (Mystruct*)&SomeDataStream; pMyStrct->Item1 = 25; int iReadData = pMyStrct->Item2; obviously the C++ way is pretty unsafe unless you are sure of the quality of the stream data when reading incoming data, but for outgoing data is super quick and easy.

How to filter and combine 2 datasets in C#

I am building a web page to show a customer what software they purchased and to give them a link to download said software. Unfortunately, the data on what was purchased and the download information are in separate databases so I can't just take care of it with joins in a query. The common item is SKU. I'll be pulling back a list of SKUs from the customer purchases database, and on the download table is a comma deleted list of SKUs associated with that download. My intention, at the moment, is to create from this one datatable to populate a GridView. Any suggestions on how to do this efficiently would be appreciated. If it helps, I can pretty easily pull back the data as a DataSet or a DataReader, if either one would be better for this purpose. Eric Sipple

File size differences after copying a file to a server vía FTP

I had an PHP script to update the webserver from a local directory. I'm migrating the script into Python, it works almost OK but after a PUT command the size of the file in the server isn't the same as the local file. Once I download again the file from the FTP server, the only difference is the CR/LF mark. It annoys me because the same script is comparing the size of the files to update. Also, it works perfectly in PHP vía ftp_put. from ftplib import FTP ftpserver = "myserver" ftpuser = "myuser" ftppass = "mypwd" locfile = "g:/test/style.css" ftpfile = "/temp/style.css" try: ftp = FTP(ftpserver, ftpuser, ftppass) except: exit ("Cannot connect") f = open (locfile, "r") try: ftp.delete (ftpfile) except: pass # ftp.sendcmd ("TYPE I") # ftp.storlines("STOR %s" % ftpfile, f) ftp.storbinary("STOR %s" % ftpfile, f) f.close() ftp.dir (ftpfile) ftp.quit() ### Any suggestions?

Tracking state using ASP.NET AJAX / ICallbackEventHandler

I have a problem with maintaining state in an ASP.NET AJAX page. Short version: I need some way to update the page ViewState after an async callback has been made, to reflect any state changes the server made during the async call. This seems to be a common problem, but I will describe my scenario to help explain: I have a grid-like control which has some JavaScript enhancements - namely, the ability to drag and drop columns and rows. When a column or row is dropped into a new position, an AJAX method is invoked to notify the control server-side and fire a corresponding server-side event ("OnColumnMoved" or "OnRowMoved"). ASP.NET AJAX calls, by default, send the entire page as the request. That way the page goes through a complete lifecycle, viewstate is persisted and the state of the control is restored before the RaiseCallbackEvent method is invoked. However, since the AJAX call does not update the page, the ViewState reflects the *original* state of the control, even after the column or row has been moved. So the second time a client-side action occurs, the AJAX request goes to the server and the page & control are built back up again to reflect the *first* state of the control, not the state after the first column or row was moved. This problem extends to many implications. For example if we have a client-side/AJAX action to add a new item to the grid, and then a row is dragged, the grid is built server-side with one less item than on the client-side. And finally & most seriously for my specific example, the actual data source object we are acting upon is stored in the page ViewState. That was a design decision to allow keeping a stateful copy of the manipulated data which can either be committed to DB after many manipulations or discarded if the user backs out. That is very difficult to change. So, again, I need a way for the page ViewState to be updated on callback after the AJAX method is fired.

How to tab focus onto a dropdown field in Mac OSX

In Windows, in any windows form / web browser, you can use the tab button to switch focus through all of the form fields. It will stop on textboxes, radiobuttons, checkboxes, dropdown menus, etc. However, in Mac OSX, tab skips dropdown menus. Is there anyway to change this behavior, or access them any other way without using a mouse?

What is Your Experience with Unit Testing in Practice?

//Yes, Virginia, there is a wikipedia. What I'm asking here is what you've found unit testing to be in your own practice. It would be helpful to know the pros, cons, obstacles to introducing unit testing, flaws in the unit testing process, value gained by unit testing, and so on that the developers here have observed in their day to day practice. **What we're doing:** I work on a web application w/ an Oracle backend. The application has been in production for 8+ years, and there are ongoing enhancement efforts along with the maintenance work. My development team does Unit Test Scripts (UTS) that aim to walk a developer through the unit test of a given code package. These UTS are 2-20 page Word documents that describe the purpose of the package, the structure, and elaborate on given modules within a package. The UTS concludes with a section that describes an Application Test of the package. This doesn't sound like unit testing to me. It sounds a lot more like system integration testing w/ a description of the package. It certainly is not automated. With our UTS practice in its current state, managing/editing/follwing the documents is not a trivial task. And when enhancements or maintenance work to a given package is needed, there are not strict testing procedures put in place to guarantee outputs are satisfactory. Instead, we have this higher level UTS to follow, which does not come close to guaranteeing correct output in various code traces.

Read binary file into a struct C#

I'm trying to read binary data using C#. I have all information about the layout of the data in the files I want to read. I'm able to read the data "chunk by chunk", i.e. getting the first 40 bytes of data converting it to a string, get the next 40 bytes, ... Since there are at least three slighlty different version of the data, I would like to read the data directly into a struct. It just feels so much more right than by reading it "line by line". I have tried the following approach but to no avail: StructType aStruct; int count = Marshal.SizeOf(typeof(StructType)); byte[] readBuffer = new byte[count]; BinaryReader reader = new BinaryReader(stream); readBuffer = reader.ReadBytes(count); GCHandle handle = GCHandle.Alloc(readBuffer, GCHandleType.Pinned); aStruct = (StructType) Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(StructType)); handle.Free(); The stream is an opened FileStream from which I have began to read from. I get an AccessViolationException when using Marshal.PtrToStructure. The stream contains more information than I'm trying to read since I'm not interested in data at the end of the file. The struct is defined like: [StructLayout(LayoutKind.Explicit)] struct StructType { [FieldOffset(0)] public string FileDate; [FieldOffset(8)] public string FileTime; [FieldOffset(16)] public int Id1; [FieldOffset(20)] public string Id2; } The examples code is changed from original to make this question shorter. How would I read binary data from a file into a struct?

Best self-balancing BST for quick insertion of a large number of nodes

I've been able to find details on several self-balancing BSTs through several sources, but I haven't found any good descriptions detailing which one is best to use in different situations (or if it really doesn't matter). Specifically, I want a BST that is optimal for storing in excess of ten million nodes. The order of insertion of the nodes is basically random, and I will never need to delete nodes, so insertion time is the only thing that would need to be optimized. I indend to use it to store previously visited game states in a puzzle game, so that I can quickly check if a previous configuration has already been encountered.

Progressive Enhancement

Jeff mentioned the concept of 'Progressive Enhancement' when talking about using JQuery to write stackoverflow. After a quick Google, I found a couple of high-level discussions about it. Can anyone recommend a good place to start as a programmer. Specifically, I have been writing web apps in PHP and would like to use YUI to improve the pages I am writing, but a lot of them seem very JavaScript based, with most of the donkey work being done using JavaScript. To me, that seems a bit overkill, since viewing the site without Javascript will probably break most of it. Anyone have some good places to start using this idea, I don't really care about the language. Ideally, I would like to see how you start creating the static HTML first, and then adding the YUI (or whatever Ajax framework) to it so that you get the benefits of a richer client?

I need to perform various sync queries on the client database, using data from the server database. For example, I want to delete all rows in the client.db tRole table, and repopulate with all rows in the server.db tRole table. Another example, I want to delete all rows in the client.db tFile table where the fileID is not in the server.db tFile table. In SQL Server you can just prefix the table with the name of the database. Is there anyway to do this in SQLite using Adobe Air?

Best .NET obfuscation tools/strategy

My product is both ASP.NET, Windows forms app and Windows service. 95% of code is .NET (VB if you must know). For IP reasons, I need to obfuscate the code. I am using an old dotfuscator (over 5 years old) and thinking it is time to move to a new gen. Anyone can recommend from his personal experience (don't just give me a list of vendors, I already have that) what works best for him? Taking into account real life issues like: - Dealing with the old problem of serialization/de-serialization: Currently, I simply tell the tool **not** to obfuscate any class data members. The pain of not being able to load data that was previously serialized with an old version is just to big - integrating the tool into the build process? - Working with ASP.NET which is a story since depending ont eh settings, you don't always have the same dll names (and you have lots of them, one per page), not all tools handle this well.
