JScript does not support passing value-type arguments by reference.

Parameters

taskHost
A null value.

progressDescription
A string that describes the progress of the event that is raised.

percentComplete
An integer used to indicate how much of the task has completed.

progressCountLow
An integer that contains the low 32-bits of the units completed.

progressCountHigh
An integer that contains the high 32-bits of the units completed.

subComponent
A string that contains more detail about the event source.

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

Remarks

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.
