Visual feedback on long running task

Question

I have a long running for-each loop, and was wondering if there was a idiomatic way to add some visual user feedback so the user doesn\'t think the application crashed.

Answer 1

You could move the work to a BackgroundWorker and use the ReportProgress method.

for (i = 0; i < count; i++)
{
    // do work
    worker.ReportProgress((100 * i) / count);
}

private void MyWorker_ProgressChanged(object sender,
    ProgressChangedEventArgs e)
{
    taskProgressBar.Value = Math.Min(e.ProgressPercentage, 100);
}
