How to handle the return key on a ClistCtrl ? I've tried to intercept 
the LVN_KEYDOWN message but the Return key is not handled !!! I've also 
tried to intercept the NM_RETURN message but it doesn't work 
Thanks in advance.

You need to override PreTranslateMessage to trap the WM_KEYDOWN(VK_RETURN) 
message like so:

BOOL 
CListCtrlEx::PreTranslateMessage(MSG* pMsg) 
{ 
  if (((GetStyle() & LVS_EDITLABELS) == 0) || (pMsg->message != WM_KEYDOWN) 
|| (pMsg->wParam != VK_RETURN)) 
    return CListCtrl::PreTranslateMessage(pMsg);

// Send the message on to the control 
  DispatchMessage(pMsg); 
  return TRUE;

}

Note that you don't need to call TranslateMessage() if you only need the 
WM_KEYDOWN message, as that function only causes a WM_CHAR(VK_RETURN) 
message to be sent to your handler.  Now you'll get the WM_NOTIFY(NM_RETURN) 
messages.
