• Game Technologies: DirectX, XNA, XACT, etc. Rotating sprites center

  I'm new to directx programming and i'm writing a simple program to help me learn. I'm using sprites and i'm trying to rotate the texture based on its current heading (the sprite is moving around). Now when i try to rotate it using a matrix, it seems the matrix is too big. My texture is only 32x32, and when i do the transformation, leaving the rotation center as NULL should set it to be the top left, according to what i've read. However, after experimenting because it didnt work, I found that if i set the center to be close to the window's center, or some larger center, it seems to fix it a bit. So it seems to me that the matrix is too big for my texture. I don't know if there is any way to set the size of it If you would like code I can ...Show All

• Visual Studio debug.assert doesn't pop up the message when condition is false

  Hi, I am working on a wpf project and debug.assert won't pop up the message when the condtion is false. public class MainApp { static string KioskName = "Kiosk" ; [ STAThread ] static int Main( string [] args) { D ebug .Assert( false , "test" );  => this won't stop if I run in debug mode (using F5). ... } I guess this might have something to do with my project set up but I can not figure out why.

• .NET Development FTP Error: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

  Hi, I am using a FTP client in my application. This FTP client is a freeware for .NET version1.1. It works fine for all files except two files. But these two files are required to FTP to a mainframe machine. I am able to FTP these two files in command prompt but getting error if I am trying to FTP through my c# application. These two files are giving two different errors mentioned below: 1. Index (zero based) must be greater than or equal to zero and less than the size of the argument list. 2.

• Visual C++ linking problems with templates

  Hi people, i'm using a templated class on my dll and it compiles and link fine, but I find that it has introduced some symbols of my templated class on the dll. It also happens with any program that includes that templated class so I have linking errors on programs that use this library because of the redefined symbols. The error comes when another lib or program use this lib, because template symbols are included on the lib althought the template is not exported and all template code is declared on the header. The specific error that happens when linking another library that uses the given is: GfxBase.lib(GfxBase.dll) : error LNK2005: "public: __thiscall gfxDimensionalUnit<2>::GetComponents(vo ...Show All

• Visual C# Toolbox Icons screwed up

  Hey everyone Recently when I opened Visual Studio 2005 I noticed that all of my icons in the tool box are screwed up.

  Okay, so a simple query. How to I use an XML file when when developing for the 360. I can do it fine in windows, but as of yet I am completly lost on how to load the file when on the 360.

  Hi, I am using XMLA Commands to process the cubes from SQL jobs. Whenever the cube processing fails The SQL jobs never reports as a failure. Is there a way to detect the failures and send alerts out. Thanks S This is known issue. It should get fixed in SQL Server 2005 SP2, that is coming pretty soon.

• Visual Studio Team System HTTPS request time out.

  I receintly had a change to the web site to use HTTPS rather than HTTP for the sign-on. Now when I record and run a web test I hang on the sign-on page loading dependants. If I turn of Parse dependant requests, it works fine. Is there a reason behind this Thanks, Tom K. Tom, Can you try setting the following at the beginning of your web test.

• Game Technologies: DirectX, XNA, XACT, etc. Native Direct3D or MDX or XNA?

    I'm in the process of choosing 3D dev platform for a non-game desktop application. I've decided to use Direct3D (not OpenGL) because the application will be developed with C# 2005. I prefer to use C# instead of C++ Direct3D if possible. But I'm very confused of which is the right direction. Basically, the application renders 3D objects in a window and allows manipulation of those objects; it should be able to show different views of a 3D scene on areas of a printed page. Any suggestion is appreciated. Thanks.   Great! It seems C++/CLI is the right way to go. I'll start to learn Direct3D rather than spending time on XNA. Please allow me to ask another question. Now that D ...Show All

• SQL Server SQL 2005, SSL - certificate request, ports

  I would like to use SSL on SQL Server 2005. With SSL, is all traffic from the client to the database on port 443 Or are other ports needed With Windows Certificate Management Snap-in, a request for a certificate assumes that there is a local Certificate Authority. I don't have one and it is my understanding that I should buy a third party certificate to avoid a man in the middle attack. With IIS there is a certificate request process. Is there something similar I should use with SQL Thank you.

• Visual C# Singleton class at runtime

  I implementet a few classes in my actual project using the singleton pattern mentioned somewhere in the MSDN: public class SingletonClass { public static readonly SingletonClass Instance = new SingletonClass(); private SingletonClass() { // some initializations here } // some more methods, fields, properties, ... } Can someone explain me when SingletonClass.Instance will be created at runtime Could it be created before "the program jumps into the main-method" In your case it will be for the first using of class. So if you have a static method and you use it without using your singleton, Instance will be created. If you don't want it, you must do your singleton like this : public class ...Show All
