backgroundworker

I have a VB.net project which uses a background worker to do some stuff. Now I want to expand the project to be able to do multiple stuff :) A user can enter an URL in a textbox and when the user click on the parse button the program creates a new tabcontrol a outputs some data. I use a hardcoded background worker for this. But now I want to run multiple background workers to do this stuff so I can't rely on hard coding the background worker(s). Is it possible to create background workers dynamically. I just don't have any idea how to set this up since I think I need to set up the different

I am developing a WPF, C# application and I have to read a very big CSV file and write to a database. This process takes a long time so I want to at least show a progress bar that grows in size as it nears completition. Now, I have the following code at the top: private readonly BackgroundWorker worker = new BackgroundWorker(); Then inside the loop I have this: worker.WorkerReportsProgress = true; worker.ReportProgress((100 * i) / 10000); and I have a private sub like this: private void worker_ProgressChanged(object sender, ProgressChangedEventArgs e) { prgBar.Value = Math.Min(e

When I used WinForms, I would have done this in my bg_DoWork method: status.Invoke(new Action(() => { status.Content = e.ToString(); })); status.Invoke(new Action(() => { status.Refresh(); })); However in my WPF application I get an error saying that Invoke does not exist for Label . Any help would be appreciated. This will help you. To Execute synchronously: Application.Current.Dispatcher.Invoke(new Action(() => { status.Content = e.ToString(); })) To Execute Asynchronously: Application.Current.Dispatcher.BeginInvoke(new Action(() => { status.Content = e.ToString(); })) Use the capabilities

I want to show the hourglass cursor and disable the window while a BackgroundWorker process runs in another thread. This is what I'm doing: Private Sub MyButton_Click(...) Dim box As New AnotherWpfWindow() box.Owner = Me ... box.ShowDialog() If (box.DialogResult.GetValueOrDefault = True) Then Me.IsEnabled = False Me.Cursor = Cursors.Wait MyBackgroundWorker.RunWorkerAsync() End If End Sub Private Sub MyBackgroundWorker_RunWorkerCompleted(...) UpdateInterface() Me.IsEnabled = True Me.Cursor = Cursors.Arrow End Sub The window becomes disabled like I want, but the cursor remains an arrow. How can

I've been searching and found that a good way to perform background work and update the GUI is using background workers. However, doing this (stupid) little task (counting from 1 to 10000) it doesn't update the label content but prints to the debug! (This is just a spike solution for another project of course...) Here's the code: public partial class MainWindow : Window { BackgroundWorker bw = new BackgroundWorker(); public MainWindow() { InitializeComponent(); } private void button1_Click(object sender, RoutedEventArgs e) { bw.DoWork += new DoWorkEventHandler(bw_DoWork); bw.ProgressChanged +=

I am currently writing a simple WPF 3.5 application that utilizes the SharePoint COM to make calls to SharePoint sites and generate Group and User information. Since this process takes awhile I want to show a ProgressBar while the groups are being generated. The desired process is as follows: User enters url and clicks button to fetch site data. ProgressBar begins animation Groups are generated and names are added to a ListView Upon completion ProgressBar animation ends The problem I am running into is that the UI is never updated. Neither the ProgressBar or the ListView makes any changes. If
