This property is used internally by the VisualStyleRenderer methods. If the class of elements specified by the Class property is not defined by the current visual style, then this property returns IntPtr.Zero.
This property value is invalidated when the visual style of the operating system changes, or when the user disables visual styles. If you access this property directly, your code should query this property again to get a new handle when the SystemEvents.UserPreferenceChanged event is raised with the UserPreferenceChangedEventArgs.Category property value of UserPreferenceCategory.VisualStyle.
