Re: Monitoring Threads

The completed and progress events are called on the same thread that calls
the RunWorkerAsync method.  If you call the RunWorkerAsync method on a
thread other than the GUI thread then you'll get cross-threading
exceptions when you try to access Control data from within those event
handlers.

Why are you calling RunWorkerAsync from a background thread?  I.e. what
are you trying to accomplish?  There's several ways to approach this, I'm
just trying to find out what way would be best.
