Hi everybody.
If I include this file in a project, I get no compiler error, but the linking process fails:
error LNK2001: ...extern symbol _IID_IDirectDraw2 and
fatal error LNK1200...
why is this??
CODE:
//
#ifndef _MABDD_
#define _MABDD_

height);

height,
dword bpp, bool vgaMode);

LPDIRECTDRAW2 ptDD;
LPDIRECTDRAWSURFACE3 ptDDPS, ptDDBB;
