mfc 樹形結構如何去掉默認選中？

 void TreeView::OnInitialUpdate()
{
    CTreeView::OnInitialUpdate();
    TVINSERTSTRUCT ti = { 0 };
    HTREEITEM hParent, Parent;
    ptheTree = &GetTreeCtrl();
    ptheTree->ModifyStyle(0, TVS_HASLINES | TVS_EDITLABELS);
    //TreeView* m_pMyView = (TreeView*)m_wndSplitter.GetPane(0, 0);
    HIMAGELIST himl;   //加入圖標  
    himl = ImageList_Create(27, 27, ILC_COLOR24, 1, 12);
    ImageList_Add(himl, LoadBitmap(AfxGetApp()->m_hInstance, MAKEINTRESOURCE(IDB_BITMAP10)), NULL);
    SendMessage(TVM_SETIMAGELIST, TVSIL_NORMAL, (LPARAM)himl);

    ti.item.mask = TVIF_TEXT | TCIF_IMAGE | TVIF_SELECTEDIMAGE;
    ti.item.iImage = 2;
    ti.item.iSelectedImage = 2;
    ti.item.pszText = _T("默認文件夾");
    ti.hParent = NULL;
    ti.hInsertAfter = TVI_ROOT;

    Parent = hParent = (HTREEITEM)SendMessage(TVM_INSERTITEM, 0, (LPARAM)&ti);

    ti.hParent = hParent;
    ti.hInsertAfter = TVI_LAST;//TVI_LAST表示節點添加在最後  
    ti.item.iImage = 0;
    ti.item.iSelectedImage = 0;
    ti.item.pszText = _T("默認筆記本");
    hParent = (HTREEITEM)SendMessage(TVM_INSERTITEM, 0, (LPARAM)&ti);

    ti.item.iImage = 3;
    ti.item.iSelectedImage = 3;
    ti.item.pszText = _T("回收站");
    ti.hParent = NULL;
    ti.hInsertAfter = TVI_ROOT;
    Parent = hParent = (HTREEITEM)SendMessage(TVM_INSERTITEM, 0, (LPARAM)&ti);

    // TODO:  在此添加專用代碼和/或調用基類
}

是哪裡初始化的不對嗎？
我試過在初始化裡放SelectItem(NULL)；沒有用。。

最佳回答：

  CTreeCtrl::SetItemState(lhItem, 0, TVIS_SELECTED);
