Return to Question

I have following code in Button and want that as many times button was clicked new thread is launched like if button is pressed 10 times then there should be 10 threads

 var t = new Thread(() => { try { var browser = new WatiN.Core.IE("http://www.google.com"); if (checkBox1.Checked == true) { browser.ShowWindow(WatiN.Core.Native.Windows.NativeMethods.WindowShowStyle.ShowMaximized);  }  else browser.ShowWindow(WatiN.Core.Native.Windows.NativeMethods.WindowShowStyle.Hide); browser.TextField(WatiN.Core.Find.ByName("q")).TypeText(textBox1.Text); //System.Threading.Thread.Sleep(5000); browser.Button(WatiN.Core.Find.ByName("btnG")).Click();  browser.Link(WatiN.Core.Find.ByText("3")).Click();  } catch (Exception ca) { MessageBox.Show(ca.Message); } }); t.SetApartmentState(ApartmentState.STA); t.Start(); 

Basic Goal is that i have four progress bar and want to run them at once as button is pressed and i donot have to use background worker have to do by this.

 var t = new Thread(() => { try {   }   }); t.SetApartmentState(ApartmentState.STA); t.Start(); 

I tried and codded

 for (i = 0; i < 4; i++)   { var t = new Thread(() => { for (double x = 0; x < 10000; x = x + 0.5)  {  progressVal=(int)x;  this.Invoke(new EventHandler(ProgressBar));  Thread.Sleep(2);    }  });  t.SetApartmentState(ApartmentState.STA); t.Start(); } private void ProgressBar(object sender, EventArgs e) {  progressBar1.Value=progressVal; } 

but cannot think of idea how to manuplate other progress bars
