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.MyBrower

            Iwb2.Silent = true;
            base.AttachInterfaces(nativeActiveXObject);
        }

        protected override void DetachInterfaces()

            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 sink

        protected override void CreateSink()
        {

            //MAKE SURE TO CALL THE BASE or the normal events won't fire

            base.CreateSink();

            events = new WebBrowserExtendedEvents(this);

            cookie = new System.Windows.Forms.AxHost.ConnectionPointCookie(this.ActiveXInstance, events, typeof(DWebBrowserEvents2));

        }

 

        protected override void DetachSink()

        }

 

        //This new event will fire when the page is navigating

        public event EventHandler BeforeNavigate;
        /// <summary>
        /// 可用于替代原来的NewWindow事件，新增了事件的Url参数支持。
        /// </summary>

        }

 

        //This class will capture events from the WebBrowser

        class WebBrowserExtendedEvents : System.Runtime.InteropServices.StandardOleMarshalObject, DWebBrowserEvents2
        {
            ExWebBrowser _Browser;
            public WebBrowserExtendedEvents(ExWebBrowser browser) { _Browser = browser; }

            //Implement whichever events you wish
            public void BeforeNavigate2(object pDisp, ref object URL, ref object flags, ref object targetFrameName, ref object postData, ref object headers, ref bool cancel)
            {

        public interface DWebBrowserEvents2
        {

 

            [System.Runtime.InteropServices.DispId(250)]

        public WebBrowserExtendedNavigatingEventArgs(string url, string frame)

            : base()
        {

            _Url = url;

            _Frame = frame;

        }

    }
}
