	default:break;

    }

// process any messages that we didn't take care of 
return (DefWindowProc(hwnd, msg, wparam, lparam));

} // ENDWINPROC ///////////////////////////////////////////////////////

anyone?

Well, for one.....

Code:

#include "MENU.H"

I don't know about the "menu" part, but the ".h" should never be caitalized.
And did you

Code:

#include "menu.h"

in both your resource AND your source file? If you didn't, that woud explain your first error. If it says it's undeclared, it's not declared.

ahh thanks. I thought that because menu.h was declared in my res file, that I didnt need it in the cpp file.
