title: Display Loading dots in a message box object
body: <p>I have a permanent message box in my windows forms application. Not to be confused with a pop up message box. The box I have displays text based on various buttons pushed in the application to update the user on whats happening. I successfully use the code below to display text in the box.</p>
  
  <pre><code>messageBox.Text += "I stick message in here" + Environment.NewLine;
  </code></pre>
  
  <p>I am interested in displaying some blinking dots in the box to indicate that something is coming. eg. "Finding stuff..." </p>
  
  <p>I have found this code for Console.Write below.<br>
  How can I make this work in my message box</p>
  
  <pre><code>for (int dots = 0; dots &lt;= 3; ++dots)
     {
        Console.Write("\rStuff will come{0}", new string('.', dots));
        System.Threading.Thread.Sleep(500); // half a sec
     }
  </code></pre>
