When implemented in a derived class, begins asynchronous processing of the tracking record.
protected public:
virtual IAsyncResult ^ BeginTrack(System::Activities::Tracking::TrackingRecord ^ record, TimeSpan timeout, AsyncCallback ^ callback, System::Object ^ state);protected internal virtual IAsyncResult BeginTrack (System.Activities.Tracking.TrackingRecord record, TimeSpan timeout, AsyncCallback callback, object state);abstract member BeginTrack : System.Activities.Tracking.TrackingRecord * TimeSpan * AsyncCallback * obj -> IAsyncResult
override this.BeginTrack : System.Activities.Tracking.TrackingRecord * TimeSpan * AsyncCallback * obj -> IAsyncResultProtected Friend Overridable Function BeginTrack (record As TrackingRecord, timeout As TimeSpan, callback As AsyncCallback, state As Object) As IAsyncResultParameters
- record
- TrackingRecord
The generated tracking record.
- timeout
- TimeSpan
The time period after which the provider aborts the attempt.
- callback
- AsyncCallback
The method to be called on completion of the operation.
- state
- Object
A user-defined object that uniquely identifies this asynchronous operation.
Returns
The result of the operation.
Remarks
Participants are expected to begin a job to process the records and return an IAsyncResult that the workflow runtime uses to wait for completion. The default implementation is to call Track and return a Completed status.
