{
  The EM_SETRECT message sets the formatting rectangle of a multiline edit control.
  The formatting rectangle is the limiting rectangle into which the control draws the text.

  Mit der EM_SETRECT Nachricht kann man die Ränder in Memo-Feldern festlegen.
}

procedure TForm1.Button1Click(Sender: TObject);
const
  
BORDER_WIDTH = 20;
var
  
Rect: TRect;
begin
  
SendMessage(Memo1.Handle, EM_GETRECT, 0, Longint(@Rect));
  Rect.Top    := BORDER_WIDTH;
  Rect.Left   := BORDER_WIDTH;
  Rect.Right  := Memo1.Width - BORDER_WIDTH;
  Rect.Bottom := Memo1.Height - BORDER_WIDTH;
  SendMessage(Memo1.Handle, EM_SETRECT, 0, Longint(@Rect));
  Memo1.Refresh;
end;
