HRESULT Cancel( );
This method has no parameters.
This method returns the following HRESULT values, as well as others.
||Job was successfully canceled.|
||Job was successfully canceled; however, the service was unable to delete the temporary files associated with the job.|
||Cannot cancel a job whose state is BG_JOB_STATE_CANCELLED or BG_JOB_STATE_ACKNOWLEDGED.|
You can cancel a job at any time; however, the job cannot be recovered after it is canceled.
For upload jobs, if the server is unavailable, there may be a delay before BITS deletes the job from the queue. BITS periodically sends a cancel request to the BITS server for up to 24 hours. If the server does not respond within the 24-hour period, BITS removes the job from the queue. If the no-progress time-out period is less than 24 hours, BITS uses the no-progress time-out period to limit the retries.
The Cancel method cancels an upload if the upload is not complete. If the upload is complete and the job is of type BG_JOB_TYPE_UPLOAD_REPLY, the method cancels the reply.
