| Pozdrav svima! Hteo bih da uz pomoc Backgroundworker-a (bgw) uradim sledece: klikom na dugme pokrecem konekciju na neku bazu podataka i istovremeno otvaram novu formu (pomocu bgw-a) koja ispisuje poruku da se vrsi konekcija i pokazuje progres bar... Pogledao sam malo ove teme: https://www.elitesecurity.org/t278600-Kako-napraviti-please-wait https://elitesecurity.org/t237778-progress-bar-otvaranje-formi ali imam problem kako da zaustavim bgw kada se uspostavi konekcija ili kada istekne timeout. Evo koda: Code: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnIzvestajZaDan.Click BackgroundWorker1.RunWorkerAsync() ... Try conn.Open() BackgroundWorker1.CancelAsync() Catch BackgroundWorker1.CancelAsync() End Try End Sub Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork If (BackgroundWorker1.CancellationPending) Then e.Cancel = True Exit Sub Else wait.ShowDialog() End If End Sub Private Sub BackgroundWorker1_RunWorkerCompleted(ByVal sender As System.Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles BackgroundWorker1.RunWorkerCompleted wait.Close() End Sub WorkerSupportsCancellation je postavljeno na True. Hvala! |
