WorkflowApplication::BeginCancel Method (TimeSpan, AsyncCallback^, Object^)
Cancels a workflow instance asynchronously using the specified time-out interval, AsyncCallback, and user-provided state.
Assembly: System.Activities (in System.Activities.dll)
public: IAsyncResult^ BeginCancel( TimeSpan timeout, AsyncCallback^ callback, Object^ state )
The interval in which the cancel operation must complete before the operation is canceled and a TimeoutException is thrown.
The method to be called when the cancel operation has completed.
An optional application-specific object that contains information about the asynchronous operation.
Return ValueType: System::IAsyncResult^
A reference to the asynchronous cancel operation.
To determine whether the cancel operation was successful, call EndCancel. EndCancel can be called from inside or outside of the method specified in the callback parameter. If EndCancel is called before the cancel operation completes, it blocks until the cancel operation completes. If the cancel operation does not complete in the interval specified by the timeOut parameter, a TimeoutException is thrown from EndCancel.
