CLIST 数组的用法 CListCtrl m_list 用法

CList <CUser*,CUser*&>  m_Usermap;

CListCtrl  m_list；//m_list 是控件CList Control 变量名；

CUser 是一个类，里面的变量名对应m_list 的变量名；

m_list.SetExtendedStyle( m_list.GetExtendedStyle() | LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES);
//3. 插入数据
m_list.InsertColumn( 0, "USER NAME", LVCFMT_CENTER, 80 );// 插入列
m_list.InsertColumn( 1, "LOGIN CLASS", LVCFMT_CENTER, 100 );

POSITION pos=m_list.GetFirstSelectedItemPosition();
if (pos)
{
int index=m_list.GetNextSelectedItem(pos);//得到选中的行号，

CUser *pUser=( CUser * )m_list.GetItemData(index);//通过这个行号而取得内容的对象（指针）；
if (pUser)
{
POSITION postemp=m_Usermap.Find(pUser);
if (postemp)
{
if (theApp.m_adoConn.ExecuteNoSelectSQL(pUser->GetDeleteSQL()))
{
m_Usermap.RemoveAt(postemp);
FillAllUerList();
ShowUserinfo();
}
}
}
delete pUser;
pUser = NULL;
}
