C# 2.0 BackgroundWorker

[kselman]

I got an app where I use the backgroundworker and when it's done it fires off the BackgroundWorkerCompleted event. Which is all good. but I need to reused the object later on. I get an exception that the BackgroundWorker has already completed. So I tried myBackgroundWorker = new BackgroundWorker(); but none of the events are hooked up any more and it just sits there. Is there anyway to reset it?:confused: or do I have to set all the properties each time I use it? -Kevin

You must reconnect the events, this is a new instance of BackgroundWorker. You can't rest the original because the thread has already completed its work and has been returned to the pool.

If you're re-starting the worker with RunWorkerAsync() the only exception would be InvalidOperationException, which means the worker is still running (IsBusy is true). What exception are you getting? --Bob

Welp.. Its working now.. not sure what was going on with it before. Unfortunately I changed too many things between testing and Im no longer receiving the Exception. It said something about "Background Worker has already completed" I think was I calling ReportProgress during the Completed event.. but I tried to recreate the problem to report to you here.. but that didnt cause the exception. I also had a pointer to a helper class that was init'd outside of the DoWork function, but I put that back in and it still works.. *shrug* sorry.. i usually dont jump the gun and post a request for help.. but It sure seemed that I could not re-use the B.W. with out hooking its events back up. Which is not the case.. Just calling RunWorkerAsync() re-runs it as expected. You reply did help, because you seemed confident to be able to re-use RunWorkerAsync and sure enough the problem was on my end.. Thanks for the quick replies.. -- Kevin

Good to hear it's working. :) I have an instance of a class which is a subclass of BackgroundWorker that reuses DoWork many many times. Never had a problem with it. - Bob
