This video tutorial will show you how to use a Progressbar and Timer In VB.NET (Visual Basic 2010/2008.

I currently have a program that runs several 'intense' queries. I added a textbox and presented status updates when a query was starting, eding and how many were left. This would suite my need, but the textbox doesn't actually display anything until all the queries are finished. It then displays all the updates at once.

I'm assuming updating the textbox in another thread would solve this issue, and that is where I am lost. How can I use a thread that receives a message from the main form running the query and have it display it in the textbox? The suits your need (sample code is there in the MSDN link). You handle its DoWork event and perform the actual query in it. You report the progress by calling its ReportProgress method. To display the reported progress, you should handle its ProgressChanged event and update the UI. You start the job by calling the RunWorkerAsync method of the background worker.

Using BackgroundWorker relieves you from manually starting and stopping threads and communicating with the UI thread to update the progress bar.

I have a progress bar I want to run in the background. I have it display, but it's just blank and does not update. Here is how I have it setup. I still cant get this to work. I do see the progress bar come up on the screen and it goes away in a few seconds, but never updates.

Just a white background. Then when I call the sub again, I see the progress bar is full, stays up a few seconds and goes away. Not sure why it's not deplaying the movement. Wait a minute. In RefreshStatus(), you have this line: 'here I do some stuff that takes about 2 seconds Since you're firing off the BackgroundWorker() from this thread, I can only assume that method runs in the main UI thread. If you have a task that takes 2 seconds, and it runs on the main UI thread, then NOTHING will be processed by main UI thread until after those two seconds are up.
