I have written a program that is running a thread to prevent lockup of my form1 while performing the tasks. I have created a progress bar on my form1 but I am having lots of trouble figuring out how to update that progress bar from my thread, which runs in a separate class.

Does anyone know a good reference?

Abhishek's answer is correct.

You could also use a BackgroundWorker. It's DoWork event is raised on a seperate thread and the ReportProgress method automatically raises the ProgressChanged event on the UI thread.

Solution 1

Create an Event for the class and use Thread to raise the event.

The event will send back the progressvalue. So inside the handler you need to reset the progress value.

Make sure you invoke the progress value from UI Thread.
