Problem getting original edit commands while editing a CLi

You could set a flag in your LVN_BEGINLABELEDIT handler and
clear it in your LVN_ENDLABELEDIT handler. In your handlers for
the ID_EDIT_ commands, execute code for the original behavior
or your new behavior, depending on the value of the flag.

For your cut/copy/paste/undo handlers:
void CDemoView::OnEditCopy()
{
   if (m_bEditingLabel)
   {
      CEdit* pLabelEdit = GetListCtrl().GetEditControl();
      if (pLabelEdit != NULL);
         pLabelEdit->Copy();
   }
   else
   {
//    Your new code
   }
}

For your ID_EDIT_CLEAR handler:
void CDemoView::OnEditDelete()
{
   if (m_bEditingLabel)
   {
      CEdit* pLabelEdit = GetListCtrl().GetEditControl();
      if (pLabelEdit == NULL)
         return;
      int nStartChar, nEndChar;
      pLabelEdit->GetSel(nStartChar, nEndChar);
      if (nEndChar <= nStartChar)   // if no characters are selected
      {                             // delete first character after   
cursor
         nEndChar = nStartChar + 1;
         pLabelEdit->SetSel(nStartChar, nEndChar, TRUE);
      }
      pLabelEdit->ReplaceSel(_T(""));
   }
   else
   {
//    Your new code
   }
}

I know this extra coding is not the implementation you were looking for;
but I hope it meets your needs.

Cheers,

Mike  Dunphy
