title: Using RectVisible on Windows Forms Control
body: <p>I'm trying to figure out if a windows forms control is visible to the user or is obstructed from view by another control or form (tabbed view). I have tried GetUpdateRect trick but it only works if the window is  minimized.  I found the <a href="http://msdn.microsoft.com/en-us/library/dd162908%28v=vs.85%29.aspx" rel="nofollow">RectVisible</a> function, but am not sure how to use it from  Windows Forms User control.</p>
  
  <p>Thanks in Advance</p>
