Comentários

Because firing of an event and generating the information sent with an event is potentially expensive, there is a mechanism for suppressing events when a client is not interested in that particular event. Every event firing method has a fireAgain parameter. If the value of this variable is false after the method returns, the caller should not fire this event again for the duration of the current execution.

For more information about the events provided by the Integration Services run-time, see Manipuladores de eventos do Integration Services.
