Méthodes

	Nom	Description
	Equals	(hérité de Object.)
	Finalize	(hérité de Object.)
	GetHashCode	(hérité de Object.)
	GetType	(hérité de Object.)
	MemberwiseClone	(hérité de Object.)
	OnBreakpointHit	This method is called whenever a breakpoint is hit within a task.
	OnCustomEvent	This method is called by tasks to raise custom task-defined events.
	OnError	This event is raised by a task or container when an error occurs.
	OnExecutionStatusChanged	This event is raised by a task or container when its execution status changes.
	OnInformation	This event is raised anytime the task is to provide information.
	OnPostExecute	This method is called immediately after the execution logic of the task completes. This event is raised by a task or container immediately after it runs.
	OnPostValidate	This method is called immediately after the validation logic of the task completes. This event is raised by a task after the task is validated.
	OnPreExecute	This method is called when the execution logic begins. This event is raised by a task or a container immediately before it runs.
	OnPreValidate	This method is called when the validation logic of the task starts. This event is raised when the validation of the task host or container begins.
	OnProgress	This method is called anytime a task experiences measurable progress.
	OnQueryCancel	This method is called at any juncture in task processing where it is feasible to cancel execution. This event is raised by tasks and containers to determine whether they should stop running.
	OnTaskFailed	This event is raised by the task host when it fails.
	OnVariableValueChanged	This event is used by the Integration Services run-time. It is not called by tasks.

Notes

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 Gestionnaires d'événements d'Integration Services.
