Use the events of the BackgroundWorker to interact with UI thread.

when the background worker have finished the work ?

Use the RunWorkerCompleted event

progressbar from the backgroundworker ?

set WorkerReportsProgress property to True, call ReportProgress method, handle ProgressChanged event.

 

[aleroot]

with this :

Private Sub BackgroundWorker1_ProgressChanged(ByVal sender As Object, ByVal e As System.ComponentModel.ProgressChangedEventArgs) Handles BackgroundWorker1.ProgressChanged
Me.ProgressBar1.Value = e.ProgressPercentage
End Sub


don't work ....
