webbrowser内存释放

WebBrowser窗口自动滚动：

this.webBrowser.Document.Window.ScrollTo(0, webBrowser1.Document.Body.ScrollRectangle.Height);

<wbr></wbr>

WebBrowser的脚本出错信息：

当页面上的脚本出错时，一般情况下会弹出脚本出错提示，如果在用WB写爬虫一类的时候，这类提示可能会导致系统不能工作，解决的发是：

(1)设置属性ScriptErrorsSurpressed = true;

(2)打开IE的设置 "Internet选项" - "高级" - 勾选"禁用脚本调试"
