you need to add a LIB file in your link options menu

quote:Main.obj : error LNK2001: unresolved external symbol _IID_IDirectDraw4
Debug/FirstEcounter.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

Try adding DXGUID.LIB to the library list in the linker options. That should fix a lot of link errors relating to IID_whatever. Also did you add DDRAW.LIB to the list as well if you don''t you''ll have even more headaches if you try to use DirecDrawCreate()

Thanks master_ball, I found that I needed dxguid.lib.
