Hide example
This code uses a button and a timer on a form. When the user clicks the button, the form disappears for the period of time specified in the Interval property of the timer control, then the form reappears:
} 
procedure TForm1.Button1Click(Sender: TObject);
begin
  Timer1.Enabled := True;
  Hide;
end;
procedure TForm1.Timer1Timer(Sender: TObject);
begin
  Visible := True;
  Timer1.Enabled := False;
end;
