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
{
[ComVisible(true)]
public class ExWebBrowser : System.Windows.Forms.WebBrowser
{

private 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 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()
{
if (null != cookie)
{
cookie.Disconnect();
cookie = null;
}
base.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>

[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 events

cancel = args.Cancel;

}

//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)
{
_Browser.OnBeforeNavigate((string)URL, (string)targetFrameName, out cancel);
}
public void NewWindow3(object pDisp, ref bool cancel, ref object flags, ref object URLContext, ref object URL)
{
_Browser.OnBeforeNewWindow((string)URL, out cancel);
}

}

[System.Runtime.InteropServices.ComImport(), System.Runtime.InteropServices.Guid("34A715A0-6587-11D0-924A-0020AFC7AC4D"),

System.Runtime.InteropServices.InterfaceTypeAttribute(System.Runtime.InteropServices.ComInterfaceType.InterfaceIsIDispatch),

System.Runtime.InteropServices.TypeLibType(System.Runtime.InteropServices.TypeLibTypeFlags.FHidden)]

public interface DWebBrowserEvents2
{

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

void BeforeNavigate2(

[System.Runtime.InteropServices.In,

System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.IDispatch)] object pDisp,

[System.Runtime.InteropServices.In] ref object URL,

[System.Runtime.InteropServices.In] ref object flags,

[System.Runtime.InteropServices.In] ref object targetFrameName, [System.Runtime.InteropServices.In] ref object postData,

[System.Runtime.InteropServices.In] ref object headers,

[System.Runtime.InteropServices.In,

System.Runtime.InteropServices.Out] ref bool cancel);

[System.Runtime.InteropServices.DispId(273)]

void NewWindow3(

[System.Runtime.InteropServices.In,

System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.IDispatch)] object pDisp,

[System.Runtime.InteropServices.In, System.Runtime.InteropServices.Out] ref bool cancel,

[System.Runtime.InteropServices.In] ref object flags,

[System.Runtime.InteropServices.In] ref object URLContext,

[System.Runtime.InteropServices.In] ref object URL);

}

public class WebBrowserExtendedNavigatingEventArgs : CancelEventArgs
{

private string _Url;

public string Url
{

get { return _Url; }

}

private string _Frame;

public string Frame
{

get { return _Frame; }

}

public WebBrowserExtendedNavigatingEventArgs(string url, string frame)

: base()
{

_Url = url;

_Frame = frame;

}

}
}

二、自己定义的窗体

using System;

//把自己的网址加入本地安全域中
RegistryKey reg = Registry.CurrentUser;
RegistryKey regSet = reg.OpenSubKey("Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings\\ZoneMap\\Domains", true);
int p = url .IndexOf("://");
string ip = url.Substring(p + 3);
string http = url.Substring(0, p);

RegistryKey regSetUrl = regSet.OpenSubKey(ip);
if (regSetUrl == null)
{
regSetUrl = regSet.CreateSubKey(ip);
regSetUrl.SetValue(http, 1, RegistryValueKind.DWord);
}
regSetUrl.Close();
regSet.Close();
reg.Close();

this.Enabled = false;
exWebBrowser1.AllowWebBrowserDrop = false;

exWebBrowser1.IsWebBrowserContextMenuEnabled = false;
exWebBrowser1.NewWindow += new CancelEventHandler(exWebBrowser1_NewWindow);

exWebBrowser1.BeforeNewWindow += new EventHandler(exWebBrowser1_BeforeNewWindow);
exWebBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(exWebBrowser1_DocumentCompleted);
exWebBrowser1.ProgressChanged += new WebBrowserProgressChangedEventHandler(exWebBrowser1_ProgressChanged);
while (exWebBrowser1.ReadyState != WebBrowserReadyState.Complete)
{
Application.DoEvents();
}
toolStripProgressBar1.Visible = false;
string title = exWebBrowser1.Document.Title;
if (title.IndexOf("无法找到资源") == 0 || title.IndexOf("导航已取消") == 0

{

this.Close();
}
}
void exWebBrowser1_ProgressChanged(object sender, WebBrowserProgressChangedEventArgs e)
{
Application.DoEvents();
if ((e.CurrentProgress > 0) && (e.MaximumProgress > 0))
{
toolStripProgressBar1.Visible = true;
}
else if (exWebBrowser1.ReadyState == WebBrowserReadyState.Complete)
{
toolStripProgressBar1.Visible = false;
}

}
void exWebBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
if (exWebBrowser1.ReadyState > WebBrowserReadyState.Interactive)
{

foreach (HtmlElement f in exWebBrowser1.Document.Links)
{

string s = f.GetAttribute("target");

if (s != null && s.ToLower() == "_blank") f.SetAttribute("target", "_self");

}

this.Text = exWebBrowser1.Document.Title;
toolStripProgressBar1.Visible = false;
}
}

void exWebBrowser1_BeforeNewWindow(object sender, EventArgs e)
{
WebBrowserExtendedNavigatingEventArgs eventArgs = e as WebBrowserExtendedNavigatingEventArgs;
if (eventArgs.Url.ToLower() != "about:blank")
{
exWebBrowser1.Navigate(eventArgs.Url);
}
eventArgs.Cancel = true;
}

void Window_Error(object sender, HtmlElementErrorEventArgs e)
{
e.Handled = true;
}

void exWebBrowser1_NewWindow(object sender, CancelEventArgs e)
{

}
void BrowserNewWindow(string url, int flag, string target, ref object data,
string header, ref bool processed)
{
processed = true;
exWebBrowser1.Navigate(url, null, (byte[])data, header);
}

private void frmBrower_FormClosed(object sender, FormClosedEventArgs e)
{
exWebBrowser1.Dispose();
GC.WaitForPendingFinalizers();
GC.Collect();
}

private void frmBrower_FormClosing(object sender, FormClosingEventArgs e)
{
this.Enabled = false;
}

}
}
