IE浏览器监控程序-监控IE窗体URL动态加载网页等信息

本程序由SHDocVw COM实现的。在项目工程内加入COM 引用:
Add Refernces - > COM Objects -> Microsft Internet Controls

主要用到SHDocVw.ShellWindowsCOM接口 ,SHDocVw.ShellWindowsClass类,
及SHDocVw.InternetExplorer 接口。

最重要的是IE窗口InternetExplorer接口，该接口继承IWebBrowser2.

IWebBrowser2接口metadata资料如下:

using System;
using System.Reflection;
using System.Runtime.InteropServices;

namespace SHDocVw

   [Guid("D30C1661-CDAF-11D0-8A3E-00C04FC9E26E")]

      [DispId(500)]

      void ShowBrowserBar(ref object pvaClsid, ref object pvarShow, ref object pvarSize);
      [DispId(106)]
      void Stop();
   }
}

看看吧，IWebBrowser2接到口内是不是有很多我们关心的方法和属性? 接下来看实现吧!

IE_Watcher类:取名为IE窗口监视器, 啥好听的名字自己取呗!

//IE窗口监视器
public class IE_Watcher
{
   private Form _owner = null;

   public IE_Watcher(Form owner)
   {
      _owner = owner;
   }

   [DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
   private static extern IntPtr GetForegroundWindow(); //WINAPI 获取当前活动窗体的句柄

   [DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
   private static extern bool SetForegroundWindow(IntPtr hWnd); //WINAPI 设置当前活动窗体的句柄

   //跨线程访问主线程内的Log控件，自定义委托
   public delegate void ShowLogHandle(string msg);

   //Txt文件记录器
   private UrlHistory _urltext = null;
   public UrlHistory UrlText { get { return _urltext; } set { _urltext = value; } }


   //获取IE浏览器打开的网页列表
   public IList GetOpenedWindows()
   {
      IList list = new ArrayList();

      //注:要引入SHDocVw COM对象哦!!! Add Refernces - > COM Objects -> Microsft Internet Controls
      //Assembly Interop.SHDocVw
      SHDocVw.ShellWindows shellWindows = new SHDocVw.ShellWindowsClass();
      string filename;
      foreach (SHDocVw.InternetExplorer ie in shellWindows)
      {
         filename = Path.GetFileNameWithoutExtension(ie.FullName).ToLower();

         //注:iexplore, 如Maxthon浏览器
         if (filename.Equals("iexplore")) list.Add(ie);
      }

      return list;
   }

   //当前监控的IE窗体对象
   private SHDocVw.InternetExplorer _ie = null;
   public SHDocVw.InternetExplorer CurrentIE { get { return _ie; } }

   //显示动态消息委托，用于跨线程
   private ShowLogHandle _showLog = null;

   //开始监控IE窗体
   public void ListenWindow(SHDocVw.InternetExplorer ie, ShowLogHandle showLog)
   {
      _ie = ie;
      _showLog = showLog;

      //置顶被监控的IE窗体
      if (new IntPtr(ie.HWND) != GetForegroundWindow()) SetForegroundWindow(new IntPtr(ie.HWND));

      //绑定事件: IE打开网页时触发这个事件
      ie.NavigateComplete2 += new SHDocVw.DWebBrowserEvents2_NavigateComplete2EventHandler(OnNavigateComplete);


      ie.TitleChange += new SHDocVw.DWebBrowserEvents2_TitleChangeEventHandler(OnTitleChange);
   }

   public void OnTitleChange(string Text)
   {
      this.ShowMsg("标题:" + Text);
   }

   //打开网页完成
   private void OnNavigateComplete(object pDisp, ref object URL)
   {
      if (_urltext != null)
      {
         _urltext.WriteHistory(URL.ToString()); //写入文本文件

         this.ShowMsg("打开:" + URL.ToString()); //显示动态消息
      }
   }

   //跨线程访问主线程内的Log控件，给控件赋值
   private void ShowMsg(string msg)
   {
      _owner.Invoke(_showLog, msg);
   }
}

将IE窗体动态消息写文件

/// <summary>
/// Txt文件记录器
/// </summary>
public class UrlHistory
{
   private string _file;

   public UrlHistory(string file)
   {
      _file = file;
   }

   public void WriteHistory(string content)
   {
      File.AppendAllText(_file, content + "\r\n");
   }
}

在ListBox控件Items属性插入自定义对象所定义的类

/// <summary>
/// IE窗体对象，用于在ListBox内显示
/// </summary>
public class IE_Item
{
   private SHDocVw.InternetExplorer _ie = null;
   public SHDocVw.InternetExplorer IE { get { return _ie; } }

   public string UrlName { get { return _ie.LocationName; } }

   public string UrlAddress { get { return _ie.LocationURL; } }

   public IE_Item(SHDocVw.InternetExplorer ie)
   {
      _ie = ie;
   }

   //关键是这个重载的方法哦!!! 在ListBox内显示的资料
   public override string ToString()
   {
      return _ie.LocationName;
   }
}

好了,测试窗体代码:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Collections;

namespace TestProject
{
   public partial class frmListenToIE : Form
   {
      //IE窗体监控器
      private IE_Watcher _ieWatcher = null;

      public frmListenToIE()
      {
         InitializeComponent();
      }

      private void frmListenToIE_Load(object sender, EventArgs e)
      {
         //实例化对象，将窗体对象作为参数传入,为什么呢?
         _ieWatcher = new IE_Watcher(this);

         //定义动态资料记录器对象
         _ieWatcher.UrlText = new UrlHistory("c:\\urlhistory.txt");
      }

      private void btnGetWindow_Click(object sender, EventArgs e)
      {
         //获取所有已打开的IE窗体
         IList windows = _ieWatcher.GetOpenedWindows();

         foreach (SHDocVw.InternetExplorer ie in windows)
         {
            //在这里加入自定义对象哦!!!
            listBox1.Items.Add(new IE_Item(ie));
         }
      }

      private void btnListen_Click(object sender, EventArgs e)
      {
         //开始监视你选中的IE窗体
         if (listBox1.SelectedIndex >= 0)
         {
            //将选中的Item转换为IE_Item对象
            IE_Item item = listBox1.SelectedItem as IE_Item;

            //item.IE
            _ieWatcher.ListenWindow(item.IE, this.ShowLog);
         }
      }

      //显示IE动态消息
      public void ShowLog(string content)
      {
         listBox2.Items.Add(content);
         listBox2.SelectedIndex = listBox2.Items.Count - 1;
         listBox2.Focus();
      }
   }
}
