  As far as you know the SetForegroundWindow function on Windows 98/2000 can
  not force a window to the foreground while the user is working with another window.
  Instead, SetForegroundWindow will activate the window and call the FlashWindowEx
  function to notify the user. However in some kind of applications it is necessary
  to make another window active and put the thread that created this window into the
  foreground and of course, you can do it using one more undocumented function from
  the USER32.DLL.

  void SwitchToThisWindow (HWND hWnd,  // Handle to the window that should be activated
  BOOL bRestore // Restore the window if it is minimized
);

}

procedure SwitchToThisWindow(h1: hWnd; x: bool); stdcall;
  external user32 Name 'SwitchToThisWindow';
         {x = false: Size unchanged, x = true: normal size}

procedure TForm1.Button2Click(Sender: TObject);
begin
  SwitchToThisWindow(FindWindow('notepad', nil), True);
end;
