備註
Because firing of an event may be expensive, the run-time engine provides a mechanism for suppressing events that you are not interested in. Every event firing method has a FireAgain parameter. If the value of this variable is false, after the method returns, the caller will not fire this event again for the duration of the current execution.
Several of the events have a subComponent parameter that allows for even greater granularity in event source identification.
