ABM_NEW message

Registers a new appbar and specifies the message identifier that the system should use to send it notification messages. An appbar should send this message before sending any other appbar messages.

fRegistered = (BOOL) SHAppBarMessage(ABM_NEW, pabd); 

Parameters

pabd

A pointer to an APPBARDATA structure that contains the new appbar's window handle and message identifier. You must specify the cbSize, hWnd, and uCallbackMessage members when sending this message; all other members are ignored.

Return value

Returns TRUE if successful, or FALSE if an error occurs or if the appbar is already registered.
