The DISPID for this event is defined in msgrpriv.h. Use this value to identify the event handler when implementing IDispatch::Invoke.

Remarks

A Messenger client receives this event if it has called the IMessengerPrivate::EnableAlertEvents method and one of the Messenger service sites that the application is connected to fires an alert.

The value of pBoolfEnableDefault indicates whether a popup window is displayed when this event is received. You must set this value to VARIANT_FALSE to specify that Microsoft Windows Messenger must not display a popup window for this alert; otherwise a popup window is displayed.
