  Do you know the line of code where the exception occurs?

  He doesn't, this is all internal code.  Best thing to do is make a small repro project and post it to a file sharing service.  Like skydrive.live.com

  Hi,
  
  Actually, I don't have a backup of the project source codes that showed the exception.  After submitting this thread, I have made a massive modification in that project source to solve the flickering problem.
  
  First time, I used transparent background colored Label for Button text and used UserControl.BackgroundImage property to set UP, DOWN, OVER images during each mouse event. But, it showed flickers. So, I tried to enable Double Buffering which in turn caused that exception.
  
  Instead of solving the problem, I took a different approach to stop flickering. As a replacement for Label,
  BackgroundImage property and Double Buffering, I drew everything, text and image on a bitmap buffer first and then used Graphics.DrawImageUnscaled method to draw the buffered image on the control's surface on each mouse event. This technique stopped the flickering.
  
  A reply from nobugz, I created almost a similar project like the first one (Caused exception), since I didn't make a backup of my first project. It works same like the previous one but didn't show any exception when the DoubleBuffered property is true. It may happen, because I didn't remember the entire source that I wrote in the first project since I made a massive modification later in that project.
  
  Anyway, thanks for replying me.
  
  Sincerely,
  
  Lockhid

  I had the same proble. Not sure why (I must have been tired at the moment - sounds good :=O) ) but I was disposing the graphics object which is wrong because I didn't created it. Check to see if you've done the same. Here's an example:
  
  

  #region

   

  OnPaint
  protected override void OnPaint(PaintEventArgs e)
  {
  Graphics g = e.Graphics;
  .
  .
  .
  //g.Dispose; //NO!!!
  }
  #endregion

  Disposing object being incorrect when not creating it was the cause of my head eche with this issue :D
