1.添加一个listctrl控件，为其关联ClistCtrl类型的变量(对象)m_list1
2.
使用 m_list1.InsertColumn添加列头
使用m_list1.InsertItem添加列表条目
使用m_list1.SetItemText为某条目的某个列段设置text
使用m_list1.SetImageList关联imagelist
使用m_list1.GetFirstSelectedItemPosition();取得所选择的条目
使用m_list1.GetItemText取de某条目的某个列段设置text
使用GetWindowLong取得list的显示类型
使用SetWindowLong设置list的显示类型
