WPS一键接入Claude：零代码实现办公AI原生化办公软件与大模型的深度集成，正从‘浏览器调用’迈向‘原生能力嵌入’。其核心原理在于绕过沙箱限制、构建可信代理层，并将AI服务抽象为WPS可识别的COM组件与本地HTTP服务。这种架构不仅规避了VBA网络禁用、API Key明文暴露、跨编码通信失败等典型技术风险，更赋予用户无需编程即可获得合同条款优化、会议纪要提炼、Excel智能公式生成等高价值场景支持。尤其在中文长文本理解与法律/商务语境适配方面，Claude展现出显著稳定性优势，成为当前WPS+AI落地中最成熟、最可控的技术路径。阅读详情

我在利用树形控件编写资源管理器。
遇到问题如下：
如何获取E盘根目录的节点。目标路径就是“E盘根目录”，我怎么把路径转化成树形控件的节点。
如图：现在已有的资源管理器界面，如下：

现在的根节点，是指向桌面的，我想改成指向Ｅ盘根目录。运行如下图：

以上，是我的问题。初始化函数代码如下：

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);

	

	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

	  // HTREEITEM hNext = GetTreeCtrl().GetNextItem(hParent,TVGN_NEXTVISIBLE);

	  // HTREEITEM hChild = GetTreeCtrl().GetNextItem(hNext,TVGN_NEXT);

	  // HTREEITEM hNext1 = GetTreeCtrl().GetNextItem(hNext1,TVGN_NEXT);

       FillTreeView(lpsf, NULL, hParent);

	   GetTreeCtrl().Expand (hParent,TVE_EXPAND);//展开“桌面”节点

	   lpsf->Release ();

	}

}

}

注意：if(strstr(szBuff,"E:") && !strchr(szBuff,'\\'))
{
hItemEdrive=hPrev;// 这个就是要返回的
}

首先，感谢老师孜孜不倦的教我，然后，我把这句话加上去后，设置断点执行时发现，本程序初始化，是遍历不到E盘的节点的，如图，只遍历了如上节点，所以，这句话被直接跳过了，“hItemEdrive=hPrev;// 这个就是要返回的”没有被执行，怎么办呢？

那就先展开 ‘计算机’
hParent = GetTreeCtrl().InsertItem(&tvis);//插入根节点
h_计算机=FillTreeView(lpsf, NULL, hParent);
GetTreeCtrl().Expand (hParent,TVE_EXPAND);//展开“桌面”节点
在 FillTreeView 里先查 ‘计算机’即：
if(strcmp(szBuff,"计算机")==0)
{
h_计算机=hPrev;
}
然后再展开 ‘计算机’

经过如上修改，，改成如上图所示了！

“'=' : cannot convert from 'void' to 'struct _TREEITEM *'”，求解释！叫你把 void FillTreeView（）改 HTREEITEM FillTreeView（）你没改。 hItemEdrive=hPrev;// 这个就是要返回的即 return hItemEdrive；

让 FillTreeView(lpsf, NULL, hParent); 返回 E:盘的 hItemEdrive 即： HTREEITEM hItemEdrive=FillTreeView(lpsf, NULL, hParent); GetTreeCtrl().Expand (hItemEdrive,TVE_EXPAND);//展开“E:”节点至于 hItemEdrive 就是 name=“E:” 的item

hItemEdrive 就是 name=“E:” 的item——————关键就是怎么实现这一步？？？？？？？？？？？？

问题我还是没有解决，您可以在我代码上改一改吗？现在不要获取路径，直接初始化到E盘根目录，E盘根目路的那个节点，我找不到，所以不知道从何下手，您可以在我代码上改一改吗
