Here is a sample having the loop in a thread:

C#

private void button1_Click(object sender, EventArgs e)
{
   System.Threading.Thread thr = new Thread(ThreadProc);
   thr.Start();
}

private void button2_Click(object sender, EventArgs e)
{
   bCancel = true;
}

bool bCancel = false;
private void ThreadProc(object o)
{
   while (!bCancel)
   {
      //Do some work
      Thread.Sleep(1);
   }
   MessageBox.Show("Loop finished");
}

Hi,

Executing infinite while is not preferable. I personally suggest you to use BackgroundWorker to do your long run process. BackgroundWorker support more then what you want.

Here are some good link to do that.

MSDN : BackgroundWorker[^]

http://www.dotnetperls.com/backgroundworker[^]

BackgroundWorker Threads and Supporting Cancel[^]

Hope this works for you,
Thanks
