When implemented in a derived class, executes when the computer's power status has changed. This applies to laptop computers when they go into suspended mode, which is not the same as a system shutdown.
Type: System::Boolean When implemented in a derived class, the needs of your application determine what value to return. For example, if a QuerySuspend broadcast status is passed, you could cause your application to reject the query by returning false.
Use OnPowerEvent to specify the processing that occurs when the system event indicated in the PowerBroadcastStatus enumeration occurs--for example, when the computer is placed in suspended mode or indicates low battery power.
