To make check boxes act like radio buttons (mutually exclusive)

If you have a list control in your dialog with the LVS_EX_CHECKBOXES style, you can make the check boxes to act like radiobuttons by adding two lines of code.. First map the LVN_ITEMCHANGED event of the list control from the class wizard and add the code shown

void CListDlg::OnItemchangedMylist(NMHDR* pNMHDR, LRESULT* pResult)
{
 NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;

 /* If the event is not fired because of any change in individual items then the oldstate and 
 newstate members of pNMListView are not used.  So check for that.*/

 if (!pNMListView->uOldState && !pNMListView->uNewState)
  return;

 // m_listctl is the member variable of the dialog which is of type CListCtl.
 BOOL bChecked = ListView_GetCheckState(m_listctl.m_hWnd, pNMListView->iItem);

 // if it's checked uncheck everything else.
 int nCount;

 if (bChecked)
  for(nCount=0;nCount<m_listctl.GetItemCount();nCount++)
   if(nCount != pNMListView->iItem)
    m_listctl.SetCheck(nCount, FALSE);
}

    else m_ListCtrl.SetItemState(m_nCurItem, INDEXTOSTATEIMAGEMASK(1), LVIS_STATEIMAGEMASK);
    }

    *pResult = 0;
    }

    The same code in OnDblclkList function may be required.

    {
    CheckDlgButton(1278,BST_CHECKED);
    CheckDlgButton(1220,BST_UNCHECKED);
    }
    else
    {
    CheckDlgButton(1278,BST_UNCHECKED);
    CheckDlgButton(1220,BST_CHECKED);
    }

    }

    where OnCheckBox1,2 are member functions of the check box
    and 1278,1220 are the checkbox IDs.
