枚举桌面应用程序lnk路径并得到对应程序的绝对路径（使用SHGetDesktopFolder函数枚举，然后使用COM查询IShellFolder，IShellLink和IPersistFile接口）

1. // 枚举桌面上应用程序的lnk路径
2. void EnumDesktopLnkPath()

4. WCHAR szPath[MAX_PATH] = {0};
5. SHGetSpecialFolderPathW(NULL, szPath, CSIDL_DESKTOPDIRECTORY, 0);

17. if(FAILED(pShell->BindToObject(pItem, NULL, IID_IShellFolder, (LPVOID*)&pFolder)))
18. {
