      string s;
      private void SetClock_Click(object sender, EventArgs e)
      {
          txtSend.Text = s;
          count++;
  
          label5.Text = count.ToString("X2");
  
          DateTime time = DateTime.Now;
  
          s = "4D-" + "1A-" + "2B-" + "3C-" +
          (label5.Text.ToString());
  
      }
  </code></pre>
