本文介绍了一种使用CListCtrl控件获取选中或点击行的方法。通过GetFirstSelectedItemPosition()和GetNextSelectedItem()函数可以有效地遍历所有被选中的项目，并获取它们的行号。

you can use the follwing functions to find out the row selected or clicked.

POSITION posList=m_MyListControl.GetFirstSelectedItemPosition( );

int nGetNextSelectedItem=m_MyListControl.GetNextSelectedItem( posList) ;

In the above sample code the "m_MyListControl" is the control member variable of the listcontrol ( member variable define through class wizard).The return value of the function "GetNextSelectedItem( posList)" is the row number selected(starts from 0 row ).

CListCtrl* pListCtrl = (CListCtrl*) GetDlgItem(IDC_YOURLISTCONTROL);
ASSERT(pListCtrl != NULL);

POSITION pos = pList->GetFirstSelectedItemPosition();
if (pos == NULL)
   TRACE0("No items were selected!/n");
else
{
   while (pos)
   {
      int nItem = pList->GetNextSelectedItem(pos);
      TRACE1("Item %d was selected!/n", nItem);
      // you could do your own processing on nItem here
   }
}
