Syntax

'Declaration

Property Value

Type: System.Boolean

Remarks

Notes to Implementers

Implementers will typically return the value of a private field or internal test as the value of this property.

Notes to Callers

Clients that poll for operation status (instead of waiting on a synchronization object) use this property to determine the status of the operation.
