Syntax

'Declaration
Public Function CheckAnyTask ( _
    jobId As Integer, _
    ByRef timestamp As Object _

)

Parameters

jobId
The job identifier. The Cluster.AddJob method returns this value. If you have a job object that has already been added to the cluster, you can access the Job.Id property to get the identifier.

timestamp
An opaque value used by the method to determine the tasks that have finished, failed, or been canceled since the last call. Set this value to NULL on the first call and then do not change the value on subsequent calls.

Return Value

An ITask interface that represents the task that finished, failed, or was canceled. Is NULL otherwise.

Remarks

This method is meant to be called in a loop for the number of tasks in a job. To determine the number of tasks in a job, access the Job.TaskCount property. The loop should sleep between iterations. The order that the tasks are returned is arbitrary.
