I am learning the basics here. I am trying to blt a bitmap to the screen. But the problem I am having is not the code. The code compiles, but when I try to link the code during compile I get this error...

---------Configuration: techs revenge - Win32 Debug-------------
Linking...
TechRevengine.obj : error LNK2001: unresolved external symbol _IID_IDirectDraw7
Debug/techs revenge.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

techs revenge.exe - 2 error(s), 0 warning(s)


Any insight on how to ratify the situation woulb be great.

I am using Visual C++ Introductory Edition version 6.0

Thanks
