參數

• taskHost
  型別：Microsoft.SqlServer.Dts.Runtime.TaskHost
  A nullnull 參考 (在 Visual Basic 中為 Nothing) value.

• progressDescription
  型別：System.String
  A string that describes the progress of the event that is raised.

• percentComplete
  型別：System.Int32
  An integer used to indicate how much of the task has completed.

• progressCountLow
  型別：System.Int32
  An integer that contains the low 32-bits of the units completed.

• progressCountHigh
  型別：System.Int32
  An integer that contains the high 32-bits of the units completed.

• subComponent
  型別：System.String
  A string that contains more detail about the event source.

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

實作

IDTSEvents.OnProgress(TaskHost, String, Int32, Int32, Int32, String, Boolean%)

備註

Each task has its own requirements, but as a general rule, a task reports progress in increments of 1 percent. OnProgress is called by the task at predetermined intervals to update listening clients on the progress of a particular task.
