分享SHGetDesktopFolder（）如何指向指定盘符（如：E盘）
如题，我在做一个资源管理器，现在程序每次运行首先指向的是桌面，我想让它指向E盘根目录，请问大家如何修改？？程序如下：
void DirTreeView::OnInitialUpdate()
{
CTreeView::OnInitialUpdate();
CTreeCtrl &Tree=GetTreeCtrl();
LPSHELLFOLDER lpsf=NULL; //IShellFolder接口
LPITEMIDLIST lpi=NULL; //ITERMIDLSIT结构体指针
HRESULT hr;
TV_ITEM tvi;
CImageList m_Image;//记录的是与树型控件关联的图像列表
SHFILEINFO sfi;//存放文件信息的结构
HIMAGELIST sys_small_icon;
sys_small_icon = (HIMAGELIST)SHGetFileInfo(NULL,0,&sfi,sizeof(sfi),
SHGFI_SYSICONINDEX|SHGFI_SMALLICON);
m_Image.Attach(sys_small_icon);
Tree.SetImageList(&m_Image,TVSIL_NORMAL);//将系统图像列表设为树控件的图象列表
m_Image.Detach ();
// 得到指向“桌面”的指针
hr=SHGetDesktopFolder(&lpsf);
//SHGetSpecialFolderLocation(NULL,CSIDL_DESKTOP,&lpi);
SHGetSpecialFolderLocation(NULL,CSIDL_DESKTOP,&lpi);
if (SUCCEEDED(hr))
{
Tree.DeleteAllItems();
char szBuff[MAX_PATH];//存放显示名称的缓冲区
TV_INSERTSTRUCT tvis; //向树型控件中插入节点时使用的结构
tvi.mask = TVIF_TEXT | TVIF_IMAGE |
TVIF_SELECTEDIMAGE | TVIF_CHILDREN ; //设置要插入的树节点信息
if(GetName(lpsf,lpi,SHGDN_NORMAL,szBuff)==FALSE)
return;
tvi.pszText = szBuff;//设置显示名称
GetNormalAndSelectedIcons(lpi, &tvi);
tvis.item = tvi;
tvis.hParent = TVI_ROOT;
hParent = GetTreeCtrl().InsertItem(&tvis);//插入根节点
FillTreeView(lpsf, NULL, hParent);
GetTreeCtrl().Expand (hParent,TVE_EXPAND);//展开“桌面”节点
lpsf->Release ();
}
}
void DirTreeView::OnInitialUpdate()
{
CTreeView::OnInitialUpdate();
CTreeCtrl &Tree=GetTreeCtrl();
LPSHELLFOLDER lpsf=NULL; //IShellFolder接口
LPITEMIDLIST lpi=NULL; //ITERMIDLSIT结构体指针
HRESULT hr;
TV_ITEM tvi;
CImageList m_Image;//记录的是与树型控件关联的图像列表
SHFILEINFO sfi;//存放文件信息的结构
HIMAGELIST sys_small_icon;
sys_small_icon = (HIMAGELIST)SHGetFileInfo(NULL,0,&sfi,sizeof(sfi),
SHGFI_SYSICONINDEX|SHGFI_SMALLICON);
m_Image.Attach(sys_small_icon);
Tree.SetImageList(&m_Image,TVSIL_NORMAL);//将系统图像列表设为树控件的图象列表
m_Image.Detach ();
// 得到指向“桌面”的指针
hr=SHGetDesktopFolder(&lpsf);
//SHGetSpecialFolderLocation(NULL,CSIDL_DESKTOP,&lpi);
SHGetSpecialFolderLocation(NULL,CSIDL_DESKTOP,&lpi);
if (SUCCEEDED(hr))
{
Tree.DeleteAllItems();
char szBuff[MAX_PATH];//存放显示名称的缓冲区
TV_INSERTSTRUCT tvis; //向树型控件中插入节点时使用的结构
tvi.mask = TVIF_TEXT | TVIF_IMAGE |
TVIF_SELECTEDIMAGE | TVIF_CHILDREN ; //设置要插入的树节点信息
if(GetName(lpsf,lpi,SHGDN_NORMAL,szBuff)==FALSE)
return;
tvi.pszText = szBuff;//设置显示名称
GetNormalAndSelectedIcons(lpi, &tvi);
tvis.item = tvi;
tvis.hParent = TVI_ROOT;
hParent = GetTreeCtrl().InsertItem(&tvis);//插入根节点
FillTreeView(lpsf, NULL, hParent);
GetTreeCtrl().Expand (hParent,TVE_EXPAND);//展开“桌面”节点
lpsf->Release ();
}
}

“根节点是桌面，我就是想让他跳到E盘”
初始化 tree 时，把 插入 E: 节点的 htreeitem 记 下来，
所有节点 插入 完 后，选择 这个 E 节点 为 当前 选择项。
在 list 中 ， 通过 遍历 E：，填充 listctrl 的 内容。
遍历 e 可以 使用 FindFileFirst 和 FindFileNext
如果 熟悉 pidl 可以 使用 pidl 来 遍历 E:

不需要用 pidl。（这是另一套）
直接 FindFileFirst 和 FindFileNext 遍历 E:
