WebBrower如何加载QQ快速登录插件

[yeah86]

在webBrower里打开QQ相关页面时，可以像如图显示快速一键登录


如何可以做到？ 请高人给个Demo最好，谢了！！

先添加引用Microsoft Internet Controls（SHDocVw）和Microsoft HTML Object Library（MSHTML）

//using System;
//using System.Runtime.InteropServices;
//using System.Windows.Forms;
//using mshtml;

void QuickLoginQQ()
{
	HtmlWindow frame = webBrowser1.Document.Window.Frames["login_frame"];
	frame = frame.Document.Window.Frames["xui"];

	var sp = (IServiceProvider)(frame.DomWindow);
	Object browser = null;
	sp.QueryService(ref IID_IWebBrowserApp, ref IID_IWebBrowser2, out browser);

	var doc = (IHTMLDocument3)((SHDocVw.IWebBrowser2)browser).Document;
	var div = (IHTMLElement2)doc.getElementById("qlogin_list");
	var a = (IHTMLElement)div.getElementsByTagName("a").item(0);
	a.click();
}

private static Guid IID_IWebBrowserApp = new Guid("0002DF05-0000-0000-C000-000000000046");
private static Guid IID_IWebBrowser2 = new Guid("D30C1661-CDAF-11D0-8A3E-00C04FC9E26E");

[ComImport(), ComVisible(true), Guid("6D5140C1-7436-11CE-8034-00AA006009FA"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
public interface IServiceProvider
{
	[return: MarshalAs(UnmanagedType.I4)]
	[PreserveSig]
	int QueryService(ref Guid guidService, ref Guid riid, [MarshalAs(UnmanagedType.Interface)] out object ppvObject);
}

using System;
using System.Drawing;

using mshtml;

namespace WinApp1
{
	public partial class Form1 : Form

		public Form1()
		{
			InitializeComponent();

			webBrowser1 = new WebBrowser
				{
					Anchor = AnchorStyles.Top | AnchorStyles.Bottom | AnchorStyles.Left | AnchorStyles.Right,
					Size = new Size(ClientSize.Width, ClientSize.Height - 40),

			Controls.AddRange(new Control[]{webBrowser1, button1});

			webBrowser1.Navigate("http://qzone.qq.com/");
			button1.Click += (s, e) => QuickLoginQQ();

这个好像不行，还总是报错。 其实我的要求就是像那个图那样显示出来登录QQ的列表，不需要让它直接登录。显示出来后让用户自己选择点击QQ登录即可！
