all the above notifications will be sent as wm_notify message: you have to check the code member of nmhdr structure for the notification message. for example, if you want to register for mouse events (eg. you want to provide a context sensitive popup menu), you must do something like this:
invoke sendmessage,hwndrichedit,em_seteventmask,0,enm_mouseevents ..... ..... wndproc proc hwnd:dword, umsg:dword, wparam:dword, lparam:dword ..... .... .elseif umsg==wm_notify push esi mov esi,lparam assume esi:ptr nmhdr .if [esi].code==en_msgfilter .... [ do something here] .... .endif pop esi
example:
the following example is the update of iczedit in tutorial no. 33. it adds search/replace functionality and accelerator keys to the program. it also processes the mouse events and provides a popup menu on right mouse click.
