  Sleep(1000);

  SubmitElement.click;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Web.Navigate('http://ui.ptlogin2.qq.com/cgi-bin/login?appid=549000912&s_url=http://qun.qzone.qq.com/group&style=11');
end;

end.

PS:这里的TCppWebBrowser是我从新导出ShDocVW.dll后，在此基础上修改而来的，如果要测试，可以用Delphi自带的Webbrowser替代即可！
