Answer 1

for(int i = 1; i <= 3; i++)  // 逐层遍历
{
    TravelLayer(pTreeCtrl, hRootItem, i);
}void Cdec16_treeDlg::TravelLayer(CTreeCtrl *pTreeCtrl, HTREEITEM hItem, int layer) 
{
    if(layer == 0)
    {
        OutputDebugString(pTreeCtrl->GetItemText(hItem));  // 输出结点文本 
    }    HTREEITEM hCurItem = pTreeCtrl->GetChildItem(hItem); 
    HTREEITEM hNextItem; 
    while(hCurItem) 
    {
        TravelLayer(pTreeCtrl, hNextItem, layer - 1); 
        hCurItem = pTreeCtrl->GetNextSiblingItem(hCurItem);
        hNextItem = hCurItem;
    } 
}
