Maybe the "process" blocks the UI thread and prevents the progressbar
control from updating. You can put the process into a separate thread
(multithreading).

To add to Herfried's reply, windows forms are not threadsafe, so you
shouldn't have a seperate thread updating your windows form. Instead you
should do thread switching by using Form.Invoke and a suitable delegate.

It's a dangerous multithreaded world out there son .. be safe.
