title: MP3 played in separate thread
body: <p>One problem was solved, another followed: In a C#-program I use following method to set a labels color to green, then playing a mp3-file and finally setting the color back to black.
  The problem is that the sound seems to be played in an extra thread, thus the time between the change of the two colors is too short (in fact, it should have the green color while the file is played).</p>
  
  <pre><code>private void playSound()
      {
          label1.ForeColor = Color.LimeGreen;
          Application.DoEvents();
  
          WMPLib.WindowsMediaPlayer wmp = new WMPLib.WindowsMediaPlayer();
          wmp.URL = @"C:\examplesound.mp3"; // duration about 30s
          wmp.controls.play();
  
          label1.ForeColor = Color.Black;
      }
  </code></pre>
  
  <p>Is there anything can be done to force the label to keep the green color whilst the mp3-file is played?</p>
