// Message map macro for cracked handlers

// Note about message maps with cracked handlers:
// For ATL 3.0, a message map using cracked handlers MUST use BEGIN_MSG_MAP_EX.
// For ATL 7.0 or higher, you can use BEGIN_MSG_MAP for CWindowImpl/CDialogImpl
// derived classes,
// but must use BEGIN_MSG_MAP_EX for classes that don't derive from
// CWindowImpl/CDialogImpl.
