unable to update progress bar with threading in C#

Question

        PROGRESS_BAR.Minimum = 0;
        PROGRESS_BAR.Maximum = 100;
        PROGRESS_BAR.Value = 0;

          


        

Answer 1

You should use the BackgroundWorker component and its ProgressChanged event.

You can call the ReportProgress method inside the DoWork handler (which runs on the background thread), then update the progress bar in the ProgressChanged handler (which runs on the UI thread).

If you really want to do it yourself (without a BackgroundWorker), you can call BeginInvoke
