DECLARE_MESSAGE_MAP
Declares that the class defines a message map. Each CCmdTarget-derived class in your program must provide a message map to handle messages.
Syntax
DECLARE_MESSAGE_MAP( )
Remarks
Use the DECLARE_MESSAGE_MAP macro at the end of your class declaration. Then, in the .cpp file that defines the member functions for the class, use the BEGIN_MESSAGE_MAP macro, macro entries for each of your message-handler functions, and the END_MESSAGE_MAP macro.
Note
If you declare any member after DECLARE_MESSAGE_MAP, you must specify a new access type (public, private, or protected) for them.
For more information on message maps and the DECLARE_MESSAGE_MAP macro, see Message Handling and Mapping Topics.
Example
class CMainFrame : public CMDIFrameWnd
{
DECLARE_MESSAGE_MAP()
// Remainder of class declaration omitted.
