I'm not sure what is causing this, but when I try to compile it I get this. This goes with most of the code in the book. compiling message: demo6_3.obj : error LNK2001: unresolved external symbol _IID_IDirectDraw4 Debug/space.exe : fatal error LNK1120: 1 unresolved externals Error executing link.exe.
