I believe I am including the cpp file in the new project. In the Properties for the project I went to Configuration Properties > C/C++ > General > And under "Additional Include Directories" i put $(SolutionDir)EngineName which includes the cpp's from that project. And they show up when I put in #include ""
If that's what you mean then yes I am including them. Maybe in the wrong place?
EDIT: If it has to do with scope or something, I actually have the D3D function(s) i'm trying to access set to public and it's still not working.
