I have two list controls (CListCtrl) on a dialog.  The user is supposed to be able to select only one item out of one control, however, if I click on one item in the first list and then click on anotheritem in the second list, the application remembers the first selection.  I only want the currently highlighted item to be the selection.  Anyone had any experience with this?

What event tells me when an item is selected in a CListCtrl?

I'm having a little trouble telling which event tells me when an item is selected.  Any suggestions?

Commented:
Try LVN_ITEMCHANGED .

Here's a good intro on how to program a list control: http://www.codeproject.com/listctrl/listctrldemo.asp

This is what the resulting code looked like...

void CSelectQaShipper::OnItemchangedAssociatedQaShippers(NMHDR* pNMHDR, LRESULT* pResult)
{
      NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
      // TODO: Add your control notification handler code here
      if (m_AssociatedQaShippers.GetItemState(pNMListView->iItem, LVIS_SELECTED)) {
            deselectQaShipperItem(&m_AllQaShippers);
      }

      *pResult = 0;
}

void CSelectQaShipper::OnItemchangedAllQaShippers(NMHDR* pNMHDR, LRESULT* pResult)
{
      NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
      // TODO: Add your control notification handler code here
      if (m_AllQaShippers.GetItemState(pNMListView->iItem, LVIS_SELECTED)) {
            deselectQaShipperItem(&m_AssociatedQaShippers);
      }

      *pResult = 0;
}


void CSelectQaShipper::deselectQaShipperItem(CListCtrl *list)
{
      POSITION pos = list->GetFirstSelectedItemPosition();
      if (pos != NULL) {
            int nItem;
            nItem = list->GetNextSelectedItem(pos);
            list->SetItemState(nItem,0,LVIS_SELECTED);
      }
}

Looks good, just make sure your list controls are set for single selection.
