C++ COM Programming for VBA Programmers

[caffeine]

I would like to implement a class in a C++ DLL for use in my Excel VBA applications.

Does anyone know of any good books or tutorials on writing C++ COM components specifically for use in VBA?

BTW, what is the difference between COM and COM+?

COM is basically the binary standard used for objects/interfaces. IUnknown etc.

COM+ includes inter-process communication, for remote/distributed/threading etc.
