Thanks in beforehand...

Dude, your missing your include files, thats why your getting all this "Undeclared identifier" errors,
eg.
#include

all you have is the #include, and no file.

no, include files jsut dont appear when you post.

Try writing the load bitmap functions again. Thats where all of your erros seem to be.

And put this up top with the lean and mean define:

#define BITMAP_ID 0x4D42

It seems like i have to include some file i dont include...
I have currently included:
windows.h
gl/gl.h
gl/glu.h
gl/glaux.h

#include stdio.h
#include stdlib.h

Try including them.. they are in my OpenGL setups, I dont know if they will help..

stdio.h is the file you want....since it includes the FILE stuff your compiler is missing..... It''s just a easy as that...

(You probably found that out already though...)

Take Care!
