implementation

{$R *.dfm}

procedure TForm1.WMActivate(var   Msg:   TWMActivate);
var
    S:String;
    wnd:HWND;
    I:Integer;
begin
If Msg.Active=0 then
begin
    wnd := Msg.ActiveWindow;
    I := GetWindowTextLength(wnd);
    SetLength(S,I+1);
    //the   text   of   the   specified   window 's   title   bar
    GetWindowText(Wnd, PChar(S),I+1);
    If Pos( '来自网页的消息', S) > 0 then
    Sendmessage(wnd,WM_CLOSE,0,0);
end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
wb1.Navigate('file://C:\Documents and Settings\Administrator\桌面\index.htm');
end;

end.

还有另一种方法，但是能力有限，怎么也看不懂。
