begin

  hHeader := SendMessage(ListView1.Handle, LVM_GETHEADER, 0, 0);

  style := GetWindowLong(hHeader, GWL_STYLE);

  style := style xor $2;

  SetWindowLong(hHeader, GWL_STYLE, style);

  SetWindowPos(ListView1.Handle, Form1.Handle, 0, 0, 0, 0,SWP_NOZORDER or SWP_NOSIZE or SWP_NOMOVE or SWP_DRAWFRAME);
