Re: CListCtrl Checkboxes

To add to what others have said I'd use:

 ON_NOTIFY(NM_CLICK, IDC_LIST, &CMyDlg::OnNMClickList)

Here is some sample code... I am using a virtual list so I am changing the
data that is being used for the list. I also like to handle more than one
item if more than one selected. This routine toggles the current settings.

Tom

// Check or uncheck item. If more than one item is selected then use the
one from the
// hit test to determine how we are setting the others (I.E., if it is off
we turn the other
// selected ones on).
void CMyDlg::OnNMClickList(NMHDR *pNMHDR, LRESULT *pResult)
{
     NMLISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
     LVHITTESTINFO hitinfo;
    *pResult = 0;

     //Copy click point
     hitinfo.pt = pNMListView->ptAction;

     //Make the hit test...
     int nItem = m_cList.HitTest(&hitinfo);

     if(hitinfo.flags != LVHT_ONITEMSTATEICON)
          return; // Didn't click on an icon

     if(m_cList.GetItemState(nItem,LVIS_SELECTED) != LVIS_SELECTED) {
         // They clicked on one that is not selected... just change it
         CMyDataInfo *pItem = (CMyDataInfo *)m_pMyDataArray->GetAt(nItem);
         pItem->m_bChecked = !pItem->m_bChecked;
         m_cList.Invalidate();
         *pResult = 1;
         return;
    }

     if(nItem != -1) {
          if(m_pMyDataArray == NULL)
              return;

          // Get the checked state from the one they clicked on
          CMyDataInfo *pItem = (CMyDataInfo *)m_pMyDataArray->GetAt(nItem);
          BOOL bChecked = !pItem->m_bChecked;

         UINT uSelectedCount = m_cList.GetSelectedCount();
         // Update all of the selected items.
         if (uSelectedCount > 0) {
             nItem = -1;
             m_cList.SetRedraw(false);
             for (UINT i=0;i < uSelectedCount;i++) {
               nItem = m_cList.GetNextItem(nItem, LVNI_SELECTED);
               pItem = (CMyDataInfo *)m_pMyDataArray->GetAt(nItem);
               pItem->m_bChecked = bChecked;
       }
       *pResult = 1;
       m_cList.Invalidate();
       m_cList.SetRedraw();
  }
 }
}
