Pure components is a Visual Extender which allows you to seamlessly add run and design time feature richness to any Windows based user interface. You know, the stuff that you usually have to spend hours adding to each control manually... a focus event here, a mouse down event there. With the Visual Extender, all that is a thing of the past. Simply place your controls on the form and add the Visual Extender. Then all you have to do is set the extended properties the component provides and you have a very slick, professional looking interface.
