CTreeCtrl 控件当前选中节点的深度？

[schlafenhamster]

void CLeftView::GetTreePath(const TVITEM *ptvi,char *pbuf)
{
	CTreeCtrl&  LeftTree=this->GetTreeCtrl();

	HTREEITEM hParentItem;
	TVITEM tvi;
	char tviname[MAX_PATH];
	char treepath[MAX_PATH];
	char drivename[MAX_PATH];
	char tmp[MAX_PATH];
// make a copy of ptvi
	memcpy(&tvi,ptvi,sizeof(TVITEM));	
	memset(drivename,0,sizeof(drivename));	
	memset(treepath,0,sizeof(treepath));	
	hParentItem=tvi.hItem;// init
    while (hParentItem)
	{
		tvi.hItem=hParentItem;// initilized !
		tvi.mask=TVIF_TEXT;  
		tvi.pszText=tviname;
		tvi.cchTextMax=MAX_PATH; 
		strcpy(tviname,LeftTree.GetItemText(tvi.hItem));
		if (strlen(treepath)) sprintf(tmp,"%s\\%s",tviname,treepath);
		else                  sprintf(tmp,"%s",tviname);
		strcpy(treepath,tmp);
// get parent
		hParentItem=LeftTree.GetParentItem(tvi.hItem);
	} 
// AfxMessageBox(treepath);
	strcpy(pbuf,treepath);
	return;
}

@schlafenhamster 你这个函数怎么用？参数是什么意思？麻烦解释一下哇。谢谢

从根节点遍历做对比

[schlafenhamster]

例如

void CLeftView::OnSelchanged(NMHDR* pNMHDR, LRESULT* pResult) 
{
	NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
	// TODO: Add your control notification handler code here
	CMainFrame   *pMain=(CMainFrame*)AfxGetMainWnd();
// get LeftTree
	CTreeCtrl&  LeftTree=this->GetTreeCtrl();

	TVITEM *pNew=NULL;
//
	char tvinamenew[MAX_PATH];
	pNew=&(pNMTreeView->itemNew);
	this->GetTreePath(pNew,tvinamenew);

	char DirName[MAX_PATH];
	char DriveName[MAX_PATH]="";

	strcpy(DirName,tvinamenew);
//
	if(stricmp(DirName,"MY COMPUTER")==0) // yes 
	{
		pMain->ListMyComputer();
		pMain->ComboMyComputer("My Computer");
		*pResult = 0;
		return;
	}
	if(stricmp(DirName,"Control 802D")==0) // yes 
	{
		pMain->List802D();
		pMain->Combo802D("Control 802D");
		*pResult = 0;
		return;
	}
// not "MY COMPUTER" and "CONTROL 802D"
	BOOL MyPC;
	MyPC=pMain->CutDriveName(DirName);
//
	if(MyPC) 
	{ // contain "My Computer"
		pMain->ListFiles(DirName,TRUE);
		pMain->ComboMyComputer(DirName);
	}
	else
	{ // contain "Control 802D"
		pMain->List802Files(DirName,TRUE);
		pMain->Combo802D(DirName);
	}
	
	*pResult = 0;
}

即只要知道当前 treeitem 就一直找到 全 路径 this->GetTreePath(pNew,tvinamenew);
