參數

  • 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.
  • 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.
