求助Shell编程

[vcHeadache]

请问，我通过IShellFolder的方法EnumObjects和Next方法返回的PIDL可以用在SHGetFileInfo吗？
我总是失败,用在IShellFolder的方法就可以，请问有这一说吗？

VS2008 SP1以上才能使用：afxShellManager->ConcatenateItem，你可自己实现

while (pEnum->Next(1, &pidlTemp, &dwFetched) == S_OK && dwFetched)
		{
			LVITEM lvItem;
			ZeroMemory(&lvItem, sizeof(lvItem));


			lvItem.mask = LVIF_PARAM | LVIF_TEXT | LVIF_IMAGE | LVIF_STATE;


			pParentFolder->AddRef();


			pItem = (LPAFX_SHELLITEMINFO)GlobalAlloc(GPTR, sizeof(AFX_SHELLITEMINFO));

			pItem->pidlRel = pidlTemp;
			pItem->pidlFQ = afxShellManager->ConcatenateItem(pidlParent, pidlTemp);////如上楼所说，需要和父级的PIDL相连接

			pItem->pParentFolder = pParentFolder;
			lvItem.lParam = (LPARAM)pItem;

			lvItem.pszText = _T("");
			lvItem.iImage = OnGetItemIcon(GetItemCount(), pItem);


			DWORD dwAttr = SFGAO_DISPLAYATTRMASK;
			pParentFolder->GetAttributesOf(1, (LPCITEMIDLIST*)&pidlTemp, &dwAttr);

			if (dwAttr&SFGAO_LINK)
			{
				dwFetched=0;
				continue;
			}

			if (dwAttr & SFGAO_SHARE)
			{
				lvItem.mask |= LVIF_STATE;
				lvItem.stateMask |= LVIS_OVERLAYMASK;
				lvItem.state |= INDEXTOOVERLAYMASK(1); 
			}

			if (dwAttr & SFGAO_GHOSTED)
			{
				lvItem.mask |= LVIF_STATE;
				lvItem.stateMask |= LVIS_CUT;
				lvItem.state |= LVIS_CUT;
			}				
			
			int iItem = InsertItem(&lvItem);

			if (iItem >= 0)
			{
				const int nColumns = m_wndHeader.GetItemCount();
				for (int iColumn = 0; iColumn < nColumns; iColumn++)
				{
					SetItemText(iItem, iColumn, OnGetItemText(iItem, iColumn, pItem));

				}
				m_nFileCount++;
			}

			CString str;
			GetItemPath(str,iItem);
			if (str.IsEmpty())
			{
				DeleteItem(iItem);
				m_nFileCount--;
			}

			dwFetched = 0;
		}
		pEnum->Release();
	}

晕，加上个颜色把注释加没了，就是想说的是：正如1楼所说，需要和父级的PIDL相连接

[jdzfjfhnui]

enum出的这个PIDL是相对路径,需要和父级的PIDL相连接,需要测试下,个人想法
