Message maps are an MFC approach to windows programming. Instead of writing a WinMain () function that sends messages to your WindProc and then writing a WindProc that checks which kind of message this is and then calls another of your functions, you just write the function that will handle the message, and you add a message map to your class that says, in effect, "I will handle this sort of message." The framework handles whatever routing is required to send that message to you.A number of macros are used in message maps:- DECLARE_MESSAGE_MAP: used in the include file to declare that there will be a message map in the source file.- BEGIN MESSAGE MAP: marks the beginning of the message map in the source file.- END MESSAGE MAP: marks the end of the message map- ON_COMMAND: used to delegate the handling of a command to a function of a class.- ON_COMMAD_RANGS: used to handle a group of commands- ON_MESSAGE: used to delegate the handling of a user defined message to a function- ON_NOTIFY: used to handle the control notification message with some extra information and calls a member function of a class.
