列表控件
?列表相關的類：CListCtrl-父類是CWnd，本質是一個控件；?CListView-父類是CView，本質是一個視圖。相當于在視圖中嵌入了一個CListCtrl控件
?列表控件的使用
- ???1.1?顯示方式：LVS_ICON/LVS_SMALLICON/LVS_LIST/LVS_REPORT
- ???1.2?圖標：CListCtrl::SetImageList；CListCtrl::GetImageList
- ???1.3?設置列：CListCtrl::InsertColumn
- ???1.4?數據的添加：CListCtrl::InsertItem-插入數據項；CListCtrl::SetItemText-設置數據項的文本?????????????
- ???1.5?遍歷數據項：CListCtrl::GetFirstSelectedItemPosition；?CListCtrl::GetNextSelectedItem；?CListCtrl::GetSelectedCount
- ???1.6?數據項的刪除：CListCtrl::DeleteItem-刪除指定索引的數據項；CListCtrl::DeleteAllItems-刪除所有項；CListCtrl::DeleteColumn-刪除指定列
- ???1.7?查找：CListCtrl::FindItem
- ???1.8?附加數據：CListCtrl::SetItemData；CListCtrl::GetItemData???
實例：新建MFC基于對話框的工程MFCList；關鍵代碼

樹控件的使用
- ?????2.1?設置圖標：CTreeCtrl::SetImageList；CTreeCtrl::GetImageList
- ?????2.2?增加節點：CTreeCtrl::InserItem增加節點，并返回節點句柄
- ?????2.3?獲取節點：CTreeCtrl::GetSelectedItem-獲取選擇的節點；CTreeCtrl::GetParentItem-獲取節點的父節點；CTreeCtrl::GetRootItem-獲取根節點?...
- ?????2.4?判斷：CTreeCtrl::ItemHasChildren-判斷節點是否有子節點
