Description
Implements the cancellation of the current asynchronous operation.
If the operation can be canceled, DoCancel returns True. When canceling the asynchronous operation, do any additional processing.
This method can be overridden by a descendant/child class to implement canceling the current asynchronous operation. By default, all asynchronous operations can not be canceled. If descendants support canceling asynchronous tasks, they must override this behavior and do the required processing.
