一个有关Shell接口的问题，好久没搞定，请教高手。

[chenjq2000]

我想用Shell来枚举所有文件夹中的内容，即是将资源管理器中的所有文件夹对象列举出来。我的方法是这样的：

第一步：SHGetDesktopFolder(&psfDeskTop)来获取桌面顶层文件夹的标志符；
第二步：psfDeskTop->EnumObjects(NULL,SHCONTF_FOLDERS,&ppenum);
do{ hr=ppenum->Next(1,&pidlItems,&celtFetched);//枚举桌面下第一层所有
//文件夹
if (celtFetched)
{ 第三步：
//用BindToObject获得下一层pidlItems对象的IShellFolder接口指针
hr=psfDeskTop->BindToObject(pidlItems,NULL,IID_IShellFolder,
(void**)&UseFolder);
hr=UseFolder->EnumObjects(NULL,SHCONTF_FOLDERS,&ppenum2);
do { hr=ppenum2->Next(1,&pidlItems,&celtFetched);
if (celtFetched2)
{//如果需要再将pidlItems传递给BindToObject以获得下一层的
//IShellFolder接口
}
} while (celtFetched2!=0);
}
} while (celtFetched!=0);


我想问每次将Next(1,&pidlItems,&celtFetched)得到的pidlItems指针传递下去给psfDeskTop->BindToObject（）会不会得到正确的IShellFolder指针，我的最终目的是枚举所有文件夹中的对象，能将资源管理器中的所有文件夹对象列举出来。那位高手有没有这方面的例子。

枚举文件夹的内容，其实就是枚举一个SysListView32内的所有东西吧.先找到窗口句柄然后得到其id,打开进程。发送消息.好像在www.vchelp.net有源码。

为什么不用cfilefind
