ON_OLEVERB
Visual Studio 2010
This macro defines a message map entry that maps a custom verb to a specific member function of your control.
ON_OLEVERB(idsVerbName, memberFxn )
The resource editor can be used to create custom verb names that are added to your string table.
The function prototype for memberFxn is:
BOOL memberFxn(
LPMSG lpMsg ,
HWND hWndParent ,
LPCRECT lpRect
);
The values of the lpMsg, hWndParent, and lpRect parameters are taken from the corresponding parameters of the IOleObject::DoVerb member function.
