I need to stop outstanding request when my service is requested to stop. -----Original Message----- From: Nick Wienholt [mailto:[EMAIL PROTECTED]] Sent: Friday, 14 June 2002 16:45 To: [EMAIL PROTECTED] Subject: Re: [DOTNET] Asynchronous calls.
Asynchronous calls use the thread pool, which doesn't provide any methods for unqueueing pending work requests. If you need to support cancellable asynchronous operations, the only option I can think of is running the method of a thread you create, and abort this thread if you no longer need the operation completed. This technique may have more performance cost than just letting the asynchronous method run through to completion, and disgrading the results - depends on the perf. cost of the asynchronous operation.
