Here are the COM examples from chapter 11. The example is a simple
COM object within an INPROC server. The COM object is implemented
in three ways: 1) using multiple inheritance (see the CoMathmi directory),
2) using nested classes (see the CoMathn directory), and 3) using MFC
(see the CoMath32 directory).

Each directory has a client program to test the CoMath objects.

To see how these work
  1) build the INPROC server
  2) Register the server in the registry
  3) Compile the accompanying "CLIENT" program
