Hi All: I have created the NEHE Crate from lesson 6. I am adding functionality with a different part. It is communicating to the PC through my SCI class. I am having the following error, and I am not sure why. Below is my files, please help! Error: c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\atlmfc\include\atlcom.h(144): error C2065: 'COINIT_MULTITHREADED' : undeclared identifier
