How to implement .cc resources into Visual C++ ?

Following the resources in torque forums, i'm often told to add files such as object.h and guibitmapcontrol.cc, etc.
Well, inside Visual C++, on the menubar option project/add to project/ files, Visual C++ recognizes .h files, but don't recognize .cc files!
Each time i try to add a .cc file from the resource, i have to choose the " *.*all files" options in the file filter, then the file disappear inside the project (no tools in Visual C++ to find files in a project by name!!!) and i don't know if it's being compiled or not...

When you include a new .cc file inside the project, wich procedures i should follow? Any other files requiring a special method of insertion?

Any help is welcome... thanks in advance.
