列表相关的类：CListCtrl-父类是CWnd，本质是一个控件； CListView-父类是CView，本质是一个视图。相当于在视图中嵌入了一个CListCtrl控件
列表控件的使用
1.1 显示方式：LVS_ICON/LVS_SMALLICON/LVS_LIST/LVS_REPORT
1.2 图标：CListCtrl::SetImageList；CListCtrl::GetImageList
1.3 设置列：CListCtrl::InsertColumn
1.4 数据的添加：CListCtrl::InsertItem-插入数据项；CListCtrl::SetItemText-设置数据项的文本
1.5 遍历数据项：CListCtrl::GetFirstSelectedItemPosition； CListCtrl::GetNextSelectedItem； CListCtrl::GetSelectedCount
1.6 数据项的删除：CListCtrl::DeleteItem-删除指定索引的数据项；CListCtrl::DeleteAllItems-删除所有项；CListCtrl::DeleteColumn-删除指定列
1.7 查找：CListCtrl::FindItem
1.8 附加数据：CListCtrl::SetItemData；CListCtrl::GetItemData
实例：新建MFC基于对话框的工程MFCList；关键代码

树控件
树控件相关类：CTreeCtrl-父类是CWnd，本质上是一个控件；CTreeView -父类是CView，本质是一个视图。CTreeView是在CView中嵌入了一个CTreeCtrl控件
树控件的使用
2.1 设置图标：CTreeCtrl::SetImageList；CTreeCtrl::GetImageList
2.2 增加节点：CTreeCtrl::InserItem增加节点，并返回节点句柄
2.3 获取节点：CTreeCtrl::GetSelectedItem-获取选择的节点；CTreeCtrl::GetParentItem-获取节点的父节点；CTreeCtrl::GetRootItem-获取根节点 ...
2.4 判断：CTreeCtrl::ItemHasChildren-判断节点是否有子节点
2.5 删除节点：CTreeCtrl::DeleteItem-删除指定节点；CTreeCtrl::DeleteAllItems-删除所有节点
2.6 附加数据：CTreeCtrl::SetItemData；CTreeCtrl::GetItemData
