The FMEVENT_HELPMENUITEM message is sent to a File Manager extension DLL procedure when the user presses F1 on a menu or toolbar command item. The extension should call WinHelp, with that function’s hwnd parameter set to the value of the extension procedure’s hwnd parameter.
FMEVENT_HELPMENUITEM uItem = (UINT) lParam; /* command item for which help is sought */
An extension DLL procedure should return zero if it processes this message.
