How to use a BackgroundWorker?

How does .net backgroundworker work?

• I import data from files in my application built in C#. If the files are not available, it sends out data import failure email. Instead I want to check if the files available 3 times and send failure email on 3rd time. I know one way is to use Backgroundworker but I'm not sure how. Any help is highly appreciated..

  This MSDN article describes in detail how to use BackgroundWorker: http://msdn.microsoft.com/en-us/library/cc221403(v=vs.95).aspx Attach all computationally heavy functions to DoWork event. Call RunWorkerASync() to trigger the DoWork event. If you want to update UI or write to log file after the task is done, do so through functions attached to RunWorkerCompleted event. If you do so outside the BW implemetation, that will happen as soon as RunWorkerASync() is called as BW runs in parallel thread. Make sure to detach all event handlers as attaching multiple times would make backgroundworker do the task multiple times
