        private void cmdFind_Click(object sender, EventArgs e)
        {
            // Disable the button.
            cmdFind.Enabled = false;

            txtResults.Text = "";
            lblTimeTaken.Text = "";

            // Get the search range.
            int from, to;
            if (!Int32.TryParse(txtFrom.Text, out from))
            {

            // Start the search for primes on another thread.
            CallAsyncWorkerDelegate doWork = new CallAsyncWorkerDelegate(CallAsyncWorker);
            doWork.BeginInvoke(from, to, null, null);
        }
