End Threadpool queued Items

[leedo2k]

Hi,
I am using the threadpool to queue threads that do network file upload. Now, the problem is that every time I close my application while the threads are running in the back ground, I expectedly get some nasty errors. Now how can I decently and gracefully shut down my application or in other words end all running threads before exiting the application?

Thanks

What code are you executing and what errors are you getting?

Hi,

I am using the following code:

 For Each file As String In IO.Directory.GetFiles(LocalFolderPath)

            DMPUploadProgress = Interlocked.Increment(DMPUploadProgress)

            Threading.ThreadPool.QueueUserWorkItem(New _  WaitCallback(AddressOf  UploadFile), _
New String() {file, DMPip, Targetstorage})

        Next file

I am not getting errors, I am still looking for a way to end the threads I throw to the thread pool in case the user wishes to abort.

Background threads do not prevent your process exiting, so if exiting without cleaning up your thread will not leave data in an invalid state then you have nothing to worry about. If you specifically need to cancel the background operation then you can explicitly create the Thread object and call its Abort method or else use a BackgroundWorker and call CancelAsync.
