The IASTimer interface, which has a global unique identifier (GUID) equal to IID_ASTIMER, extends the IASControl interface. The timer is set to fire at a specified interval. When it matures, it fires a WM_TIMER message to the event sink. The control’s identifier is contained in the low-order word of wParam, the form’s identifier in the high-order word.
