visual studio question
Author
I am trying to compile and execute a program using visual studio 2008. When I run the program it compiles and then tries to run but only displays a black screen for a moment and then goes back to my code screen.
I'm sorry, I tried my tarot cards but didn't get any useful information from them about your problem. I AM going to meet a tall dark stranger though.
Perhaps you could provide a little more detail, like, your code (wrap in source /source tags), thanks. :)

The program is designed to exit if certain things fail to happen. One of these is the failure to load the required resources.
On mine, the program initialize correctly until it it tries to load paddle.bmp, which I don't have.
I suspect you may not have them, or they are in the wrong place.
Do you have all the pictures it is trying to load? And do you have them in the correct directory which is probably (not an expert with VS2008) Projects\ProjectName\Debug
You can track the flow of the program as it executes in times such as this with breakpoints, the use of OutputDebugString, or using error codes on the returns.

As empirical2 said, it'll fail if the images aren't present. On my Visual Studio 2005, it failed (because of the bitmaps) while compiling. I created "dummy" bitmap files, placed them in the root folder with my .cpp file, and the program compiled and ran..."successfully". I say it that way because I'm not sure what it's supposed to do; it doesn't crash.
What it does:
Continues to alternate between a black and white screen, with an intensity that would even make a non-epileptic convulse until their limbs flew off. I then inserted a dreaded Sleep() call, to see what it was doing, and noticed that, at seemingly random times, the white becomes a smaller, centered, rectangle.
Compiled using the latest DirectX SDK (DXSDK_Jun10.exe).

I'd use the debugger to step through your code to follow the flow of logic and see where it's going "wrong".

well I used the debugger and got a: Cannot find or open the PDB file. This is associated with some .dll files.
That's normal. VS doesn't find debug symbols for some installed dlls.
Really, step through with the debugger (F10 per default) and you'll see where your program maybe exits too early.

that also happened in my VC 6 to develop SDL application. When I moved to VC 2005 I thought that the problem were resolved...But it doesn't
