Two CListCtrls on a dialog

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?

You need to set up an event handler to handle the selection for either list control, remember which item is selected in each control, and then manually deselect any selections in the other control. Something along these lines:

    // item_selected1 contains the index of the item selected in ctrl 1
    UINT selstate = m_listctrl1.GetItemState(item_selected1, LVIS_SELECTED);

    // Toggle the selected state.
    m_listctrl1.SetItemState(item_selected1, ~selstate, LVIS_SELECTED);
    m_listctrl1.RedrawItems(item_selected1, item_selected1);

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.
