I was using VC++ 6 Ent. I had compiled a DirectDraw7 example file, but after compiled there were some error when linking objects. Debug window said: example.obj:error LNK2001: unresolved external symbol _DirectDrawCreate@16 example.obj:error LNK2001: unresolved external symbol _IID_IDirectDraw7 LIBCD.lib(crt0.obj):error LNK2001: unresolved external symbol _main what shoud I do? I can do ''furthure'' learning with those errors Would you PLEASE helping me? Thx

Go to Project Settings on the Project menu. Under the linker tab, add ddraw.lib. Read your compiler docs.

Thanks so much. That''s help a lot.
