FORWARD_WM_NOTIFY

VOID FORWARD_WM_NOTIFY(
    hwnd, 	
    idFrom, 	
    pnmhdr, 	
    fn	
   );	

Sends or posts the WM_NOTIFY message.

• Returns a value whose meaning depends on the fn parameter.

hwnd

Handle to the window that receives the WM_NOTIFY message.

idFrom

Identifier of the control sending the message.

pnmhdr

Address of an NMHDR structure that contains the notification code and additional information. For some notification messages, this parameter points to a larger structure that has the NMHDR structure as its first member.

fn

Function that sends or posts the WM_NOTIFY message. This parameter can be either the SendMessage or PostMessage function.

The FORWARD_WM_NOTIFY macro is defined as follows:

#define FORWARD_WM_NOTIFY(hwnd, idFrom, pnmhdr, fn) \ 
    (void)(fn)((hwnd), WM_NOTIFY, (WPARAM)(int)(id), \ 
    (LPARAM)(NMHDR FAR*)(pnmhdr))
