方法
名称 | 说明 | |

注释
The Integration Services runtime includes this event interface that is passed by the runtime to various components that execute within a package, such as tasks, enumerators, and so on. Events are raised by tasks using the IDTSComponentEvents interface that is supplied during execution and by the run-time execution engine.
The Fire<x> methods can be called at design time and during execution. Typically, during component design, the FireError, FireInformation, and FireWarning methods are called to provide user feedback when a component is incorrectly configured. Events that are raised during component design are displayed in the Task Pane. Additionally, components can define custom events and then raise them during execution using the FireCustomEvent method.
