You can't use RegisterWindoweMessage() with a MESSAGE_MAP.  The compiler
expects the MESSAGE_MAP values to be compile-time constants, thus they need
to be known to the compiler ahead of time.  But RegisterWindowMessage()
return a dynamic run-time value that is not known until the application is
actually running, thus the compiler has nothing to compile with.  That is
why I mentioned earlier that you'll have to override your form's inherited
WndProc() method in order to intercept the registered message.
