How can I make the progress bar update fast enough?

Question

I\'m using a progress bar to show the user how far along the process is. It has 17 steps, and it can take anywhere from ~5 seconds to two or three minutes depending on the weath

Try invoking the call to the waiting.setProgess() method since waiting seems to live in another thread and this would be a classic cross thread call (which the compiler warns you about if you let him).

Since Control.Invoke is a bit clumsy to use I usually use an extension method that allows me to pass a lambda expression:

waiting.ThreadSafeInvoke(() => waiting.setProgress(...));

.

public static class ControlExtension
{
    public static void ThreadSafeInvoke(this Control control, MethodInvoker method)
    {
        if (control != null)
        {
            if (control.InvokeRequired)
            {
                control.Invoke(method);
            }
            else
            {
                method.Invoke();
            }
        }
    }
}
