is it possible to add OpenGl simulation to my other visual C++ project. if possible then how can i do that. please give me some suggession.

Hey,
that depends on what kind of VC++ project you have there. If it is a MFC or .NET application with windows you have to go another way than if you have a console app. Taking user input is crucial for OpenGL apps, how would you play any OpenGL based game without being able to use input?

If you mean to say: can the rest of my App take user input while using OpenGL (then you probably have windows open) then this is a bit tricky, best solution is probably using multithreading..
