无论我做什么，显示的内容都不会更新：'（

        msgLog.DocumentText = docText;
        Application.DoEvents();

        HtmlTable table = new HtmlTable();
        table.Width = "100%";

        HtmlTableRow tr = new HtmlTableRow();

        tr.Cells[0].Width = "100%";

        table.Rows.Add(tr);

        InsertHtmlControl(table, msgLog);

    }

    public static void InsertHtmlControl(HtmlControl c, WebBrowser wb)
    {

        // create a HtmlTextWriter;
        StringBuilder sb = new StringBuilder();
        StringWriter sw = new StringWriter(sb);
        HtmlTextWriter htmlw = new HtmlTextWriter(sw);

        // render the control as html
        c.RenderControl(htmlw);

        ////invoke the script passing in the html 
        //object[] p = new object[1];
        //p[0] = (object)sb.ToString();

        //Trace.WriteLine("Invoking: " + sb.ToString());

        //wb.Document.InvokeScript("appendHtml", p);

        HtmlElement body = wb.Document.GetElementsByTagName("body")[0];

        body.InnerHtml = sb.ToString();

        wb.Update();

        htmlw.Close();
        htmlw.Dispose();

        sw.Dispose();
