MFC Edit Control: How to know when text is pasted from clipboard to 'CEdit' control?

[amarcode]

Q: How to know when text is pasted from clipboard to 'CEdit' control?

A: In the destination application derive all edit controls from 'CEdit' and override 'OnChar()' and 'OnContextMenu()':

void CMyEdit::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags) 
{
  if(nChar==22) // Ctrl-V
  TRACE("CTRL-V used to paste the text\n");
  CEdit::OnChar(nChar, nRepCnt, nFlags);
}

void CMyEdit::OnContextMenu(CWnd* pWnd, CPoint point) 
{
  CMenu menu;
  menu.CreatePopupMenu();
  if(CanUndo())
    menu.AppendMenu(MF_STRING,1,_T("Undo"));
  else
    menu.AppendMenu(MF_STRING|MF_GRAYED,1,_T("Undo"));

  menu.AppendMenu(MF_SEPARATOR,2);
  int nSel1,nSel2;
  GetSel(nSel1,nSel2);
  if(nSel1!=nSel2)
    menu.AppendMenu(MF_STRING,3,_T("Cut"));
  else
    menu.AppendMenu(MF_STRING|MF_GRAYED,3,_T("Cut"));

  if(nSel1!=nSel2)
    menu.AppendMenu(MF_STRING,4,_T("Copy"));
  else
    menu.AppendMenu(MF_STRING|MF_GRAYED,4,_T("Copy"));

  if(::IsClipboardFormatAvailable(CF_TEXT))
    menu.AppendMenu(MF_STRING,5,_T("Paste"));
  else
    menu.AppendMenu(MF_STRING|MF_GRAYED,5,_T("Paste"));

  if(nSel1!=nSel2)
    menu.AppendMenu(MF_STRING,6,_T("Delete"));
  else
    menu.AppendMenu(MF_STRING|MF_GRAYED,6,_T("Delete"));

  menu.AppendMenu(MF_SEPARATOR,7);
  CString s;
  GetWindowText(s);
  if(s.IsEmpty())
    menu.AppendMenu(MF_STRING|MF_GRAYED,8,_T("Select All"));
  else
    menu.AppendMenu(MF_STRING,8,_T("Select All"));
  
  int nRet = menu.TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON | TPM_RETURNCMD, point.x, point.y, this);
  switch(nRet)
  {
    case 1:
      Undo();
      break;

    case 3:
      Cut();
      break;
  
    case 4:
      Copy();
      break;

    case 5:
      TRACE("Popup menu used to paste the text\n");
      Paste();
      break;
  
    case 6:
      Clear();
      break;
  
    case 8:
      SetSel(0,-1);
      break;
  }
}
