怎样实现与SHSimpleIDListFromPath同样的功能？
需要将一些特殊路径转换为PIDL,例如“D:\NUL\CON”,或者转换一个暂时不存在的路径。目前SHSimpleIDListFromPath函数可以实现，但不敢保证在未来版本的windows中可用
MSDN上介绍的另一种实现方法：
An alternative to this function is as follows:
1.Call SHGetDesktopFolder to obtain IShellFolder for the desktop folder.
2.Get the IShellFolder's bind context (IBindCtx).
3.Call IShellFolder::ParseDisplayName with the IBindCtx and the path.
但是我不知道第二步该怎样操作。英文非常菜，靠Google翻译，所以很多东西读不通也就不知道是怎么回事

我哭了，这个功能真复杂。网上搜不到，只有细细的翻MSDN，总算让我翻到线索了。
你不给我分真对不起我了。
