I don''t know if I''m late posting this or anything, but I found that MSVC 6.0 has a ton of source code in : C:\Program Files\Microsoft Visual Studio\VC98\CRT\SRC assuming that you installed in the default directory. Looking through it appears to be the source code for all the .h''s that are used. "You can observe a lot just by watching."- Yogi Berra

another way of seeing the source for the headers that you use, like windows.h and GL/gl.h is to highlight the header name in the program (not including the >< or the "") and right-click and click Open Document "whatever.h"
