Appendix A: Message Map Functions in the MFC Library



Overview


MFC now uses a static_cast within the message map macros to improve type checking. The type checking enforces return and parameter types. The stricter type checking produces error messages when potentially unsafe message handlers are used. For example, here's the ON_COMMAND macro:

#define ON_COMMAND(id, memberFxn) { WM_COMMAND, CN_COMMAND, (WORD)id, (WORD)id, AfxSigCmd_v, static_cast<AFX_PMSG> (memberFxn) }

The following tables list the message map functions in the MFC library, including the handlers for WM_COMMAND messages, child window notification messages, window notification messages, and user-defined message codes.
