Only classes derived from the CCmdTarget class can get the benefits of message map.For that we need to use DECLARE_MESSAGEMAP, BEGIN_MESSAGEMAP, END_MESSAGEMAP macros.
when we declare a message map it will create an array to keep all the information about the messages to be handled.
Overall the messages are handled by the base class CCmdTarget.
Virtual function is one of the best concept of oops,its for managing objects and functions.
No need of vtables to handle messages.
