How do I force a repaint from a custom control?

[Tom P.]

I am making a custom control (a ProgressBar) and was wondering how do
I force the control to paint like the base ProgressBar does? As it is
my control doesn't paint until the main execution loop let's it,
usually with Application.DoE vents. But even if I do an
Application.DoE vents() in my OnPaint it doesn't paint the control.
Thanks,

Hi Tom,

Hmm, is it a WinForms app? Anyway, you need to use sort of threads approach
to "live update" your progress bar. The links below can help you:
