The Name property represents the name of the control, which is a unique identifier of a control.

private int _progress Bar Maximum; public int Progress Bar Maximum private int _progress Bar Current; private int Progress Bar Current private void Replace Text In Files() void worker_File Processed(object sender, Event Args e) Why doesn’t the Progress Bar update itself when the Progress Bar Current is incremented as indicated above in code.

In Order to process the Progress Bar update code on UI thread, I changed my code to use Background Worker. Code Behind for User Control: I created a test project with your initial code.

What I am trying to do is have it so that each file copied gets the Progress Bar a little closer to the end until they are all copied. You should definitely be performing long-running operations in a worker thread - but then you can't update the UI directly from the worker thread. -- Jon Skeet - I was able to do the following: // Display the Progress Bar control. Visible = true; // Set Minimum to 1 to represent the first file being copied. Minimum = 1; // Set Maximum to the total number of files to copy. I don't know if using Do Events() is a good thing either. And the progressbar updates based upon the number of files I have.

In such cases (copying, writing several files) I use to update the Progress Bar according to the file size of the individual file related to the overall size of all files. But now that I think about it that's not really what I meant to do.

You are going to see when it is OK to use the foreground and when it is not OK but better to use Background Worker.

While much of this code may be production ready, you should be aware that this code intentionally implements a foreground process that is an example of what not to do.

After a while I found that you have declared the Progress Bar Current property as private. So it doesn’t seem necessary to update the property on the UI thread. Invoke call is made internally when reading back the updated property value.

Please consider: foreach (List View Item item in list View Files.

The two larger 36MB files do not update the bar at all until the end and then the blue bars on the Progress Bar only go up to halfway when completed.
