　　Windows Shell的一个功能在于管理并提供方法存取系统中的众多对像，這些对像包括了文件，网路上的计算机，控制面板程序，回收站等等，为了识别每一个对像，Windows Shell使用了Item ID来表示它們，而Iten ID Lists用来表示一个对像的路径。所以，ITEMID和ITEMIDLIST的关系类似于文件名和路径的关系。如果只对文件系统而言的话，ITEMIDLIST可以看成是路径的另一中表示法，Windows Shell也提供了函数來进行转化。



用SHBrowseFolder获取结构体：LPCITEMIDLIST
然后通过SHGetPathFromIDList来取出获取的路径信息

、、、、实例尽量简单点吧
