Question on Background worker

[Flack]

Hey guys,

I'm trying to update a progress bar for a long running process that updates
quite frequently. I also would like the GUI to remain responsive to
resizing/moving/repainting, etc.

When I use the below methods in a background worker thread the GUI doesn't
remain very responsive. Is it because the progress bar is being updated very
frequently? If I have a real process running that updates just as fast, what
can I do to keep the GUI running smoothly?

Thanks,

Flack,

Scale back on how often you report progress. Do it once every 1000
iterations of the loop instead and see what happens. Increase or
decrease the rate to throttle how often the UI should update.
