title: Let user specify timer time?
body: <p>I want the DispatcherTimer to read time values from the textbox : objTextBox.
  I tried this code however it seems that TimeSpan is not compatible with strings or did I do anything wrong?</p>
  
  <p>Error: Argument 1: cannot convert from 'string' to 'long'</p>
  
  <p>Also; Does the Time have to look like this in textbox: 0, 0, 1 or 00:00:01?</p>
  
  <p>Code here:</p>
  
  <pre><code>    private void testing()
      {
          string theText = objTextBox.Text;
          DispatcherTimer dispatcherTimer = new DispatcherTimer();
          dispatcherTimer.Tick += new EventHandler(listjob3_Tick);
          dispatcherTimer.Interval = new TimeSpan(theText);
          dispatcherTimer.Start();
      }
  </code></pre>
