获取选择的行
//m_List是要处理的对象
int nItem = m_List.GetNextItem(-1, LVNI_SELECTED);
获取指定行指定列的值
m_List.GetItemText(nItem, nSubItem);
允许多选时，获取选中行进行处理
POSITION pos = m_list.GetFirstSelectedItemPosition();
if (pos == NULL)
{
TRACE0("No items were selected!\n");
}
else
{
while (pos)
{
int nItem = m_list.GetNextSelectedItem(pos);
TRACE1("Item %d was selected!\n", nItem);
// you could do your own processing on nItem here
}
}
