[dba-VB] VS2008: ProgressBar displays on XP, not on Vista

Hi Shamil

Thanks, that is very close to my scenario. I googled for something like that but without success. So I better fire up a BackgroundWorker.

Hi Shamil

I did, also progressBar1.Refresh(), but to no avail. 
It looks like there's no shortcut to the BackgroundWorker ...

Hi Gustav,

Try this "trick":

System.Windows.Forms.Application.DoEvents();

Hi all

I run a simple routine copying data between three databases in six steps.
This lasts for about two minutes; in between a ProgressBar is advanced. 
This works fine when the app runs under WinXP, but under Vista 32-bit with
the Aero interface either nothing happens or the ProgressBar updates once at
some random step.

The general advice is to use the BackgroundWorker for such tasks like the
series of updates, but I'm lazy and wonder if a small trick can bring the
ProgressBar to the surface and update under Vista as well.
Any hints?
