OpenGL with Visual Studio

I am porting some linux codes to windows (VS 2005 Professional). In the original code, I am not using glut.h, instead only uses gl.h and glu.h. Where can I download these files. Also, I am downloaded the libraries and dll for windows and it included glut.h and says that it includes gl.h and glu.h. is that correct? I don’t have to downloads anything else? Please reply

I am not expert with Visual Studio, but I though that it installs automatically Opengl development files. Have you set path correctly in your project? have tried to locate Opengl headers in the VS directory?
