DirectX 9 question

[Zaita]

It's a very specific technique. Not something that is "C++". You are going to want to visit game development forums specifically. This is a technique, not a language problem you are having.

It doesn't matter what language you find it implemented in you should be able to easily implement this in C++. And this funny enough, is a C++ forum.

I would suggest trying http://www.gamedev.net They have a bunch of good tutorials.
http://www.cplusplus.com/src/winbmp.zip will show you how to write a basic BMP loader.
