I tried a few things and got it to work. I add status strings coming in to an ObservableCcollection which is databound to the ListBox.

This seems to work:
internal ObservableCollection Messages = new ObservableCollection();

public void UpdateStatus(string status)
{
Dispatcher.BeginInvoke(DispatcherPriority.Background,
(SendOrPostCallback)delegate {Messages.Add(status); }, null);
}
Then bind the ObservableCollection to the ListBox.ItemSource.

Thank you for the great post. For the ProgressDia...

Thank you for the great post.

For the ProgressDialog, I was wondering how to change 'UpdateStatus' if we used a ListBox rather than a TextBlock. Each status update could be added to a fixed size ListBox and scroll as it updates.

Hi Naga. The error means just what it says. Your worker delegate does not accept the correct arguments. It needs to take a single IProgressContext argument.

Hi,
I am getting error at StartWork() method, it is saying like "ProgressWorkerDelegate" has some invalid arguments, please let me know how to solve this issue?.

Mike,
Has anyone converted your code to VB? I used the code converter at Telrik to convert the original and this update for Progress Bars and was not succesful.

Hi Mike - it sounds like you are updating the progress bar too often. If you are updating it in a tight loop, then you are going to hamper performance. You really only want to update it when it will make a noticeable change.

Mike, what about performance? Is there a way to ma...

Mike, what about performance? Is there a way to make the progress bar calls not take time away from running the algorithm. Currently when I use this setup, if I leave off the progress updates, the algorithm can take 5 seconds or so to run. Adding the calls to update the progress brings the run time up to almost 30 seconds.

2009-11-04T12:26:07.393-08:00

I've been trying to convert this code into VB.Net and I'm stuck on one section that's giving me trouble, as I don't fully understand the C# syntax.

Dispatcher.BeginInvoke(DispatcherPriority.Background,
(SendOrPostCallback)delegate { Progress.SetValue(ProgressBar.ValueProperty, progress); }, null);

Can anyone give me a hand with this? (I've tried some online code converters, but they all fail on this line)

Thanks! This has been really helpful.
