Замечания

The Script component developer does not use the ScriptComponent class directly, but indirectly, by coding the methods and properties of the ScriptMain class, which inherits from ScriptComponent through the UserComponent class.

The developer can use the ComponentMetaData property of the ScriptMain class to raise errors, warnings, and informational messages to the data flow engine.

Примеры

The following code sample shows how the Script component developer can use the ComponentMetaData property to raise an error from within the Script component.

Private myMetaData As IDTSComponentMetaData100
...
myMetaData = Me.ComponentMetaData
myMetaData.FireError(0, "Script Component", _
  "ERROR", String.Empty, 0, pbFireAgain)
