Manipulate bitmap file in OpenGL _Help

In this forum someone know how to manipulate a bmp file in Visual C++ (read and import it into OpenGL and manipulate with it) , plz help me !!!
I’m doing my project in my college

Why exactly would you think this is an advanced question? OpenGL knows nothing about BMP files - you have to write the code to load it yourself (or use something like DevIL). You then pass the data to OpenGL. To find out how to load it yourself, look at MSDN (you can also read about basic opengl there.

If your assignment is for College, then your lecturer should be teaching you the things you need to know (like how to use google).
