Progress bar

[jaworekplay]

To enable progress bar to work we have to start new thread and start the worker in the manner as follows: private void DEACT_Load(object sender, System.EventArgs e) { // Start the BackgroundWorker. backgroundWorker1.RunWorkerAsync(); } and then private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) { for (int i = 1; i <= 100; i++) { // Wait 100 milliseconds. Thread.Sleep(100); // Report progress. backgroundWorker1.ReportProgress(i); } } and after private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e) { // Change the value of the ProgressBar to the BackgroundWorker progress. progressBar1.Value = e.ProgressPercentage; // Set the text. this.Text = e.ProgressPercentage.ToString(); } This should be sufficient to provide asynchronous update. ;)
