首先需要引用Microsoft.mshtml,AxInterop.SHDocVw 一些方法: webBrowser.ScriptErrorsSuppressed = true;//允许脚本调试 webBrowser.WebBrowserShortcutsEnabled = true;//允许快捷键 /*********************一些事件的处理*******************/ webBrowser.CanGoForwardChanged += new EventHandler(webBrowser_CanGoForwardChanged); webBrowser.CanGoBackChanged += new EventHandler(webBrowser_CanGoBackChanged); webBrowser.StatusTextChanged += new EventHandler(webBrowser1_StatusTextChanged); webBrowser.Navigating += new WebBrowserNavigatingEventHandler(webBrowser1_Navigating); webBrowser.Navigated += new WebBrowserNavigatedEventHandler(webBrowser1_Navigated); webBrowser.DocumentTitleChanged += new EventHandler(webBrowser1_DocumentTitleChanged); webBrowser.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted); webBrowser.Disposed += new EventHandler(webBrowser1_Disposed); (webBrowser.ActiveXInstance as SHDocVw.WebBrowser).NewWindow3 += new SHDocVw.DWebBrowserEvents2_NewWindow3EventHandler(FrmIEExplorer_NewWindow3); webBrowser.ProgressChanged += new WebBrowserProgressChangedEventHandler(webBrowser1_ProgressChanged); /*********************************************************/  private WebBrowser CreateNewWebBrowser()  {      WebBrowser _axWebBrowser = new WebBrowser();      _axWebBrowser.Tag = new HE_WebBrowserTag();      _axWebBrowser.Dock = DockStyle.Fill;      TabPage _TabPage = new TabPage();      _TabPage.Controls.Add(_axWebBrowser);          RegisterEvent(_axWebBrowser);      flatTabControl1.TabPages.Add(_TabPage);      flatTabControl1.SelectedTab = _TabPage;      _ActiveWebBrowser = _axWebBrowser;      btn_Remove.Enabled = flatTabControl1.TabPages.Count >= 1;      // tblCloseTab.Enabled = true;      return _axWebBrowser;  }  /// <summary>  /// 新窗口事件  /// </summary>  /// <param name="ppDisp"></param>  /// <param name="Cancel"></param>  /// <param name="dwFlags"></param>  /// <param name="bstrUrlContext"></param>  /// <param name="bstrUrl"></param>  void FrmIEExplorer_NewWindow3(ref object ppDisp, ref bool Cancel, uint dwFlags, string bstrUrlContext, string bstrUrl)  {      Cancel = true;          ppDisp = (this._ActiveWebBrowser.ActiveXInstance as SHDocVw.WebBrowser).Application;//这里是关键      WebBrowser _axWebBrowser = CreateNewWebBrowser();      _axWebBrowser.Navigate(bstrUrl);  } //读取网页内容 private void ReadDoc(IHTMLDocument2 doc) {     int inputcount = doc.all.length;     foreach (IHTMLElement item in doc.all)     {         if (item.id == "_petName" || item.id == "userNameTopLine")         {             this.rich_src.AppendText("     id:");             this.rich_src.AppendText(item.innerText);         }         //this.rich_src.AppendText("     id:");         //this.rich_src.AppendText(item.id == null ?
