利用WebBrower封装的自己的浏览器MyIE源代码.doc

利用WebBrower封装的自己的浏览器MyIE源代码用途：封装只能访问自己的web应用解决问题：1、弹出窗口不会跳出，解决了出现IE浏览器的问题2、获得访问界面的Title作为浏览器的Title一、封装WebBrowser（源自互联网网友提供的代码，已不知出处，非常感谢）using System;using System.Collections.Generic;using System.Text;using System.Windows.Forms;using System.ComponentModel;using System.Runtime.InteropServices;namespace MyQuery.MyBrowerComVisible(true)public class ExWebBrowser : System.Windows.Forms.WebBrowserprivate SHDocVw.IWebBrowser2 Iwb2;protected override void AttachInterfaces(object nativeActiveXObject)Iwb2 = (SHDocVw.IWebBrowser2)nativeActiveXObject;Iwb2.Silent = true;base.AttachInterfaces(nativeActiveXObject);protected override void DetachInterfaces()Iwb2 = null;base.DetachInterfaces();System.Windows.Forms.AxHost.ConnectionPointCookie cookie;WebBrowserExtendedEvents events;/This method will be called to give you a chance to create your own event sinkprotected override void CreateSink()/MAKE SURE TO CALL THE BASE or the normal events wont firebase.CreateSink();events = new WebBrowserExtendedEvents(this);cookie = new System.Windows.Forms.AxHost.ConnectionPointCookie(this.ActiveXInstance, events, typeof(DWebBrowserEvents2);protected override void DetachSink()if (null != cookie)cookie.Disconnect();cookie = null;base.DetachSink();/This new event will fire when the page is navigatingpublic event EventHandler BeforeNavigate;/ / 可用于替代原来的NewWindow事件，新增了事件的Url参数支持。/ CategoryAttribute(操作), DescriptionAttribute(经过扩展的NewWindow事件，使用继承后的WebBrowserExtendedNavigatingEventArgs类型参数实现Url参数支持)public event EventHandler BeforeNewWindow;protected void OnBeforeNewWindow(string url, out bool cancel)EventHandler h = BeforeNewWindow;WebBrowserExtendedNavigatingEventArgs args = new WebBrowserExtendedNavigatingEventArgs(url, null);if (null != h)h(this, args);cancel = args.Cancel;protected void OnBeforeNavigate(string url, string frame, out bool cancel)EventHandler h = BeforeNavigate;WebBrowserExtendedNavigatingEventArgs args = new WebBrowserExtendedNavigatingEventArgs(url, frame);if (null != h)h(this, args);/Pass the cancellation chosen back out to the eventscancel = args.Cancel;/This class will capture events from the WebBrowserclass WebBrowserExtendedEvents : System.Runtime.InteropServices.StandardOleMarshalObject, DWebBrowserEvents2ExWebBrowser _Browser;public WebBrowserExtendedEvents(ExWebBrowser browser) _Browser = browser;
