说明：  左右两个ListBox互相交换数据，VC++版源码实现，也就是文本数据在两个ListBox之间相互传递，这种用法在WEB开发中应用广泛 ，最早发现是在招聘网站、IT产品网站，用于高级产品搜索或职位搜索时候，方便选择类别，减少程序出错率，我想在VC中这应该也是个不错的应用。
(Exchange data with each other left and right ListBox, VC++ version of source code to achieve, that is, text data is passed between two ListBox, this usage is widely used in WEB development, first discovered in the recruitment website, IT products, websites, for advanced product search or job search time, choose a category to facilitate and reduce the process error rate, I think this should be in the VC is a good application.)
