• Game Technologies: DirectX, XNA, XACT, etc. Problems with playing Sound

  My Sound class is the exact same one as the one from this tutorial: http://xbox360homebrew.com/blogs/audio/archive/2006/09/11/193.aspx I have done exactly as that tutorial states and have managed to get the music to play in the game I am working on. However, there are situations where the music will stop playing for unknown reasons. For example, when I am in my Game's menu, the music plays just fine and never stops. However, when I click the start game button and start playing my side scrolling game, the music stops after 20 seconds or so of playing my game. I should also mention that when I shrink my client window, the music plays just fine. So it only accures when the client window is at  ...Show All

• Visual Studio Express Editions Problem installing.

  Hey. I just downloaded Visual C++ Express Edition 2005. I go to intall it, everything seems to go ok, and then it gets stuck here. It will not go anywhere past that. I don't know what I should tell you about my system but here is what I could think of.

First, you can reinstall easily if you every need to. Also, if you don't install everything the first time, it is always possible to refresh from the CD image when you wan ...Show All

• Visual Studio Express Editions Multithreading for dummies

  Okay, I want to create a simple worker thread. Easiest method possible. Press a button and have some stuff happen in the background. From my reading I thought AfxBeginThread would be the way to go, but I'm getting an "identifier not found" error when I try and compile. Is there a header I need to include for this Or something else I need to do to make it work Thanks. I managed to get threading working with _beginthread instead. But I can't figure out how to have my thread talk to my GUI. I'm using the visual c++ form designer to create a form, and then have a button click spawn a thread to do some stuff. But Id really like the thread to be able to print stuff in my textbox for example to keep tr ...Show All

• Visual C# Date format validation

  Hi there: I plan on allowing my users to customize the date input and display format. I toyed with the idea of giving then a finite list of formatting options (like MM/dd/yy, MM/dd/yyyy, etc.), but then I realized that they could be educated in using the formatting attributes, thus gaining access to the whole spectrum of date formatting attributes. Now, because they need to be educated, there will be mistakes. This date formatting string is entered through a setup process and it is then saved "as is" in some data store. Because of human input, the format string will need to be validated. Apart from the obvious checks and balances (allowed characters, "usual" formats, etc.), is there any way that the data for ...Show All

• Visual Studio Team System How do I recover from missing .mdf and .ldf files

  Hello, My project is expecting .mdf and .ldf files in the DesignDB folder of my solution folder. Somehow they have disappeared. This is undoubtedly due to a machine crash earlier today. How do I recover from this position How do I tell the project to recreate the design database and therefore those files On a slightly different thread, shouldn't you do something to mitigate the risk of this happening Machine crashes do happen as we all know. -Jamie Hi Jamie, AFAIK the answer (at least for RTM and the last CTP's) is different than what you posted. 1. You open the project with VS. 2. VS will try to ATTACH the <projectname>_GUID database using the saved mdf and ldf files. (and compares ...Show All

• Visual C++ LNK2019

  Hello, this will probably seem very easy to any c++ guru but I'm having a problem with the error below. I'm writing a CustomAction dll in C++ 8.0 for an MSI installation. I have a function called UpdateDispatcherAppConfig and in that function I want to be able to call a shared function which is defined in a separate class file. I don't want the shared function to be exported, I have included it so I can share some of the code that is being called from two different custom actions.

• Visual Studio Tools for Office How to catch all unhandled exceptions

• Visual C# Interfaces oversold???

  First, I must admit that I am a C# novice and so I probably don’t have as much knowledge and experience on the subject of interface as most of you guys reading this post. After reading a few books on C# and interface design, I still can’t see and understand the real power of interface unless of course, we are talking about interfaces as a powerful concept in OOP ‘only’ and not as a powerful concept in the general sense. When I was first learning OOP I was quite suspicious about the ‘excellent features’ that OOP claims to be able to deliver to the world and I was right. For example, in reality OOP offers very little if any, code reuse. I am now having the same suspicion about interfaces even though I see a lot nice words used to d ...Show All

• SQL Server Examples for using DirectRow method?

  Hi! I was just wondering if there are any examples on how to work with the Script Editor, and more specifically how to use the DirectRow method I've seen some examples that say that the editor automatically creates the methods DirectRowTo<output buffer>, but it doesn't say how that is done. If I just specify Row.DirectRow(output buffer #), it says that the method is protected. Any help or just pointing me in the right direction would be greatly appreciated! Thanks!

• Visual Basic Error occuring for one user only after upgrading to Visual Studio 2005

  Here is my question: I have a Visual Basic Windows Forms application that was developed in Visual Studio.NET 2003 and was recently upgraded to Visual Studio 2005. After reinstalling the application one of my users is getting an error, but the strange thing is that this is happening to one user only, out of about 25. So basically, the application works fine for everybody except this one user. The error was not occurring before we upgraded to Visual Studio 2005. I have installed and reinstalled .NET Framework 2.0 on his machine a couple of times, same thing with the application, but the error is still occurring. I doubt it's something in my code because otherwise it would be happening to everybody else. I have tried unsucc ...Show All
