Delete Thumbnails

A thumbnail can be removed from the ThumbnailItemCollection by calling Remove, RemoveAt, or Clear. The removed thumbnails will not be displayed on the next paint.

If the Thumbnail was generated with an Hbitmap that was obtained through ToHbitmap, the application must call DisposeHbitmap to free all resources associated with the Hbitmap.
