Hi,
I'm trying to develop this vb.net application which gathers info.
When I start the gathering process, I refresh text-fields in the form to see
progress and to see where it gets.
This works fine as long as the application has the focus.
When I start an other application or switch to an other application (e.g.
taskmanager, outlook), the form-refresh of my application stops.
When I put the focus back to my application, the form remains blank. the
refreshes do not occur ?!?
In taskmanager the application gets status not-responding, but it does what
it's supposed to do.
What can I do to correct this ?

Hi Jobi,
That sounds not as normal behaviour, it even will be a problem because when
you refresh all the time because I thought that it is trying to get the
focus, did you do something to prevent that?

Complain to the WinXP developers. See 3rd paragraph: http://msdn.microsoft.com/library/en...sagequeues.asp
The developers forgot that a not responding window may still display
something even if it intentionally does not accept input. :-(((((((((((((
This ghost window "feature" can not be turned off.
Two ways around: Either use application.doevents (carefully!) or put the
work in a different thread. Both may lead to much more work than we had to
do in previous OS versions.

I guess Arim Zingler's reply describes my problem.
Thanks

100% on target !
I'll dig into the workarounds.
Do you have a "checklist" regarding the pitfalls for application.doevents ?

Only one item on the list: ;-)
Watch for re-entrance. Means: During processing a message, another message
may occur and be processed - this includes that the user can close the form
but your process still continues.
