C backgroundworker progress bar not updating

As an example, I wrote a simple application that displays the problem at hand: Notice how the “Start” button is re-enabled slightly before the Progress Bar hits completion.

In this simple toy example, the problem does not seem like such a big deal.

Run Worker Async) Are you sure that transfered files are the same? Seek seems off to me; it returns to 0 offset after the first pass and rereads first packet Size of data in second pass. The only reason file transfer works is because it is read and sent in one packet.

As a quick assistance, try some of this information from this site.

As a side note, most editions of Windows Vista/ 7 ship with the Aero theme.

On clients using the Aero theme, there exists a small lag between the actual value and what is displayed in the Win Forms Progress Bar control.

I've not done it with any of the cool C# 3.5 functions, but I bet you could work up a lamba expression to do the same thing.

One of the most important things that differentiates a “quick and dirty” application from one that has been designed well is how the application’s user interface behaves during lengthy operations.

Clearly in this case you're blocking the paint events for the progress bar in so doing. What happens in the Background Worker stays in the Background Worker!

The reason for this is that Aero animation will cause a progressive transition between values of the Progress Bar to create a visually stunning effect.

Usually this is not an issue, but if you have an event that is supposed to be triggered on completion of a process, then this discrepancy can cause bugs/ confusion for users.

If you aren't sure what thread you are running on, you can check the value of Invoke Required (if your class is a System. Invoke() function to make sure the update is processed on the UI thread for the control you are working with.

In my sample code below I'm creating a delegate function type and declaring the invoked function in advance....

I think it's something very small, but I can't find it. private void Start(object sender, Routed Event Args e) Background Worker bg = sender as Background Worker; File Info fi = new File Info(@"File"); length = fi.
