Parametri

• DtsContainer
  The task.

• variable
  The variable that has changed.

• fireAgain
  A Boolean that indicates whether this should continue firing or stop firing. A value of true indicates that it should continue firing.

Osservazioni

This event is called by variables whenever their value is changed. OnVariableValueChanged should not be called by tasks, because it is raised by the run-time engine by the variables. If a task calls OnVariableValueChanged, the method will return success but no event handler will be executed.
