AccessviolationException was unhandled + HtmlDocument

Hi,

I create a function that retuns System.Windows.Forms.HtmlDocument  type dinamically.

Please see my code below.

public HtmlDocument GetDoc(string url)
        {
            string html = string.Empty;
            using (WebBrowser browser = new WebBrowser())
            {
                if (!string.IsNullOrEmpty(html))
                {
                    try
                    {
                        browser.DocumentText = html;
                        //browser.DocumentType = 
                        //BrowserUrl = new Uri(url);
                        //System.Uri.TryCreate(url, UriKind.RelativeOrAbsolute, out BrowserUrl);
                        //browser.Url = browserUrl;
                        //browser.AllowWebBrowserDrop = false;
                        browser.ScriptErrorsSuppressed = true;
                        //browser.Document.Write("Test rendering for simple run");
                        browser.Document.OpenNew(true).Write(html);
                        //browser.Document.Write(html);
                        //return browser;
                        return browser.Document;
                    }
                    catch (Exception ex)
                    {
                        throw ex;
                    }
                }
                else
                {
                    return null;
                }
            }
        }

My OS is WIndows XP and Browser is IE 8. Please Help.
