backgroundWorker1.RunWorkerAsync(this);
}
}
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)

try{
this.Show();
this.notifyIcon1.Visible = false;
this.ShowInTaskbar = true;

What exactly are you trying to do here with the background worker?
RE: I have a problem with Background worker in C# - leam_lidara - 05-25-2012
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());RE: I have a problem with Background worker in C# - leam_lidara - 05-26-2012
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();
