  TForm2 = class(TForm)
    WebBrowser1: TWebBrowser;
    Button1: TButton;
    ListBox1: TListBox;
    procedure FormShow(Sender: TObject);
    procedure Button1Click(Sender: TObject);
    procedure WebBrowser1DocumentComplete(ASender: TObject;
      const pDisp: IDispatch; var URL: OleVariant);
  *******
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form2: TForm2;
  ok:Boolean;

implementation

{$R *.dfm}
//{$APPTYPE CONSOLE}

procedure TForm2.Button1Click(Sender: TObject);
var
  I: Integer;
begin
//循环读取网站
for I := 0 to ListBox1.Count-1 do
begin
  WebBrowser1.Navigate(ListBox1.Items[i]);

  while True do
  begin
    if ok then break;
    Application.ProcessMessages();
  end;
  ok:=false;
end;

end;

procedure TForm2.FormShow(Sender: TObject);
var
  filename:string;
  myfile:TextFile;
  s:string;
  i:integer;
begin
//全局变量初始化
ok:=false;
//初始化列表框
filename:=ExtractFilePath(Application.ExeName)+'\list.txt';
AssignFile(myfile,filename);
try
