title: How to close BalloonTip programmatically?
body: <p>I have a Tray icon in my application. I am showing the balloon tip for 20 seconds, when I am loading something in the background. But, if the background load gets completed early, say in 10 seconds, I would like to hide the balloon tip. Currently the only way to hide the balloon tip is to click the close icon in the balloon tip.</p>
  
  <pre><code>    Public Tray As NotifyIcon
      Tray = New NotifyIcon
  
      Tray.BalloonTipIcon = ToolTipIcon.Info
      Tray.BalloonTipText = "Loading"
      Tray.BalloonTipTitle = "Please Wait"
      Tray.ShowBalloonTip(20 * 1000)
  </code></pre>
  
  <p>Is it possible to hide the balloon tip programmatically before the specified time is reached?</p>
