Answer / abhijit
* It is the base class for MFC's message map architecture
* Message map functionality is given through its virtual
member function OnCmdMsg
*** Owing to the way message map architecture is
implemented there is no provision for multiple inheritance
in MFC (1 window can not have two parents ... if the
derived class cant handle a message... and both parents
can... which parent should handle!!!)
