Look in the C# Windows Forms / C# Controls menu here at CodeProject. There is an entire section on Progress Controls.

You have to tell the ProgressBar to update, but be careful not to directly access UI elements from a different thread than the one they were created in. So you should define a delegate, for example

private delegate void SetProgressValueDelegate(int val);

and a method in your class to update the ProgressBar (its signature must match the delegate):

private void SetProgressValue(int val)
{
progressBar1.Value = val;
}

Then you can safely invoke the method from your thread by calling:

Invoke(new SetProgressValueDelegate(SetProgressValue), new object[] { newValue });

where newValue is the value to set the ProgressBar to. Regards, mav -- Black holes are the places where god divided by 0...
