title: Double buffered ListBox
body: <p>I have a CheckedListBox (WinForms) control (which inherits from ListBox; googling shows that the problem is with ListBox) that is anchored to all four sides of its form.  When the form is resized, the ListBox has an ugly flicker.  I tried inheriting CheckedListBox and setting <code>DoubleBuffered</code> to <code>true</code> in the ctor (this technique works with other controls, including ListView and DataGridView), but it had no effect.</p>
  
  <p>I tried adding the <a href="http://msdn.microsoft.com/en-us/library/ms632680.aspx" rel="noreferrer"><code>WS_EX_COMPOSITED</code></a> style to <code>CreateParams</code>, and this helped, but makes the form resize mush more slowly.</p>
  
  <p>Is there any other way to prevent this flickering?</p>
