[message] WM_TIMER

Posted to the installing thread's message queue when a timer expires.

The message is posted by the GetMessage or PeekMessage function.

 

c++

#define WM_TIMER                        0x0113

 

Parameters

wParam

The timer identifier.

lParam

A pointer to an application-defined callback function that was passed to the SetTimer function when the timer was installed.

Return value

Type : LRESULT

An application should return zero if it processes this message.

 

Remarks

You can process the message by providing a WM_TIMER case in the window procedure. Otherwise, DispatchMessage will call the TimerProc callback fundtion specified in the call to the SetTimer function used to install the timer.

The WM_TIMER message is a low-priority message. The GetMessage and PeekMessage function post this message only when no other higher-priority messages are in the thread's message queue.
