backgroundworker

In my .NET C# project I have used a "BackgroundWorker" to call a method in a different class. The following is the source-code of my main form public partial class Form1 : Form { public Form1() { InitializeComponent(); } testClass t1 = new testClass(); private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) { t1.changevalue(1000); } private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e) { label1.Text += Convert.ToString(e.ProgressPercentage); } private void button1_Click(object sender, EventArgs e) { backgroundWorker1.RunWorkerAsync(); } } and

I have a background worker running a long database task. i want to show the progress bar while the task is running. Somehow the background worker won't report the progress of the task. This is what i have: BackgroundWorker _bgwLoadClients; _bgwLoadClients = new BackgroundWorker(); _bgwLoadClients.WorkerReportsProgress = true; _bgwLoadClients.DoWork += new DoWorkEventHandler(_bgwLoadClients_DoWork); _bgwLoadClients.RunWorkerCompleted += new RunWorkerCompletedEventHandler(_bgwLoadClients_RunWorkerCompleted); _bgwLoadClients.ProgressChanged += new ProgressChangedEventHandler(_bgwLoadClients

If I am in a function in the code behind, and I want to implement displaying a "Loading..." in the status bar the following makes sense, but as we know from WinForms is a NoNo: StatusBarMessageText.Text = "Loading Configuration Settings..."; LoadSettingsGridData(); StatusBarMessageText.Text = "Done"; What we all now from WinForms Chapter 1 class 101, is the form won't display changes to the user until after the Entire Function completes... meaning the "Loading" message will never be displayed to the user. The following code is needed. Form1.SuspendLayout(); StatusBarMessageText.Text = "Loading

I'm trying to get the size of a file that is hosted on a FTP Server and put it in a Label while the `BackgroundWorker works in the background. I'm using " Try " to get the value, however the value is caught on the first attempt. After downloading, if I press to try to get it again then it works. Note : The progress bar also does not work on the first try. Image What I have tried: Private Sub BWorkerD_DoWork(sender As Object, e As System.ComponentModel.DoWorkEventArgs) Handles BWorkerD.DoWork Dim buffer(1023) As Byte Dim bytesIn As Integer Dim totalBytesIn As Integer Dim output As IO.Stream Dim

I have a progress bar and backgroundworker in VB.Net that I would want to work in a different form as given below: Form1() { MaxRows = 10 for i = 0 to MaxRows then // Update my value on the progressbar .... next } ProgressBarForm Private Sub ProgressBarForm_Shown(sender As Object, e As EventArgs) Handles Me.Shown TransferProgressBar.Visible = True ProgressBarBackgroundWorker.RunWorkerAsync() End Sub Private Sub ProgressBarBackgroundWorker_DoWork(sender As Object, e As ComponentModel.DoWorkEventArgs) Handles ProgressBarBackgroundWorker.DoWork For i = 0 To TransferProgressBar.Maximum 'Dim

I would like to know what to use for tasks that need alot of performance. Backgroundworker , Thread or ThreadPool ? I've been working with Threads so far, but I need to improve speed of my applications. BackgroundWorker is the same thing as a thread pool thread. It adds the ability to run events on the UI thread. Very useful to show progress and to update the UI with the result. So its typical usage is to prevent the UI from freezing when works needs to be done. Performance is not the first goal, running code asynchronously is. This pattern is also ably extended in later .NET versions by the
