Use a background thread for the long-running task.

Hello Gabi,
How are you doing?

For preventing an application from freezing, if you applicaiton uses some
loop. Try using
Application.DoEvents() method
MSDN URL:
http://msdn.microsoft.com/library/de...ventstopic.asp
This will enable the user to take actions while your form/procedure works.

I hope this helps.

Thanks

or problably if he used timer control......when progressbar ending 100%
then set timer1.enabled to false. i already done mpg project. so it
will not prevent frozen

Oh.. oh.. be very careful with the DoEvents(). Don't use it straight in the
loop or work code.
The application will become slow as well and you can kill your application
without cleaning up if you use DoEvents()...
Instead use it with a timer something like with a status/statusbar property

Private Sub tmStatusMonitor_Tick(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles tmStatusMonitor.Tick
If strStatus <> "Ready" Then 'strStatus is the custom property
sbStatus.Text = strStatus
Application.Doevents()
End If
End Sub

Hope this helps

I have some long running code and at the start I show a status form using
ShowDialog and disable the background form. In the long running loop, I
update the showdialog form via a property called countdone and an
application.DoEvents that gets called in each loop. I have tested it and the
user can't close the form until either the loop completes or the user presses
cancel in the dialog form. It seems to work ok and prevents the user from
killing the application except thru the task manager.

in that case use application.doevents
