title: Not able to update UI in windows form
body: <p>I have one windows form in which I have a number of images shown using delegate. When one event is fired I need to remove image and put label saying image not shown. I have created new thread to update UI. My problem is for 8 image my event is called 8 times. But label is coming for only 4 or 5 labels only. Can anyone help me with this error? Or suggest any new way to do so?</p>
  
  <p>Thanks in advance.</p>
