重载实现的数字编辑框控件，详见代码，初学者使用(Overloaded implementation of digital editing box controls, see code for beginners)

This article is an elementary tutorial that shows you how you can have auto-completing combo-boxes in your Managed C++ programs. Of course it wouldn t be much of a difficulty to convert the code straight to C# or VB .NET. The technique described in this article requires you to have the final release of VS.NET. It will not work on any beta version of VS.NET including beta 2 as I found out after two days of frustration.
