Any problem with that code below? I have a problem while I try to show form or any thing related to form such as textbox, listbox, button.... Any command? Thank before hands.

Code:

private void Timer_Tick(object sender, EventArgs e)
        {
            if (backgroundWorker1.IsBusy == false)
            {
                backgroundWorker1.RunWorkerAsync(this);
            }
        }

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
    {
    try{
      this.Show();
      this.notifyIcon1.Visible = false;
      this.ShowInTaskbar = true;
      this.WindowState = FormWindowState.Normal;
     }catch(Exception ex)
         {
             MessageBox.Show(ex.Message);
         }
    }

What exactly are you trying to do here with the background worker?

I want to show form with it and use other tools such as textbox but I have a problem and cannot access to show form or cannot access to use other method of textbox.[/align]

Why are you doing this in a background worker just to show a form? If you want to show the form and do it in a multi-threaded method:

Code:

new Thread(x => new Form1().Show());

It's not work..... any thing else?

What do you mean not working? Post the code you have.

I think that Background Worker doesn't work with Windows Form component! So I need your suggestion to use Background worker with Windows Form component.

Sorry late night yesterday for me, I didn't even test the code I gave before because I was just about to head to sleep (start work again today). Invoke it to create a new instance of the form.

Code:

public Form1()
{
    InitializeComponent();
    bg_worker.DoWork += new DoWorkEventHandler(bg_work);
    bg_worker.ProgressChanged += new ProgressChangedEventHandler(bg_progress);
    bg_worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bg_completed);
}

public BackgroundWorker bg_worker = new BackgroundWorker();

private unsafe void button1_Click(object sender, EventArgs e)
{
    bg_worker.RunWorkerAsync();
}

private void bg_work(object sender, EventArgs e)
{
    this.Invoke((MethodInvoker)delegate { new Form1().Show(); });
}

private void bg_progress(object sender, EventArgs e)
{
    //Progress for other things here
}

private void bg_completed(object sender, EventArgs e)
{
    //Completed code here
    bg_worker.Dispose();
}
