From version 1.1 of the .NET framework Windows Forms comes with support for the XP style with the Application.EnableVisualStyles() API call. However the results of calling this can be unexpected – all of the display elements on your forms that load resources from imagelists (such asd toolbars, treeviews, and list views) fail to paint correctly.
Tow ork around this you need to rememer to call Application.DoEvents() after calling Application.EnableVisualStyles() and before calling Application.Run()
There is an example of this on MSDN
