网站投票程序

　　早前几个朋友需要帮忙投票，而现在的投票网站都基本上有个限制：一个ip一天只能头一次票。从网络上搜索到破解方法有两种：1、使用拨号网络接入，每次拨号成功后会自动分配ip；2、固定ip接入，可以采用代理方式，欺骗投票程序。基于这个思路做了两个版本的程序，下载地址

　　1、拨号网络接入。这个方式采用的思路，开启两个线程：第一个做一死循环，拨号，投票，断网；第二个线程轮询处理异常窗口。

　　该方法使用win API。同时使用网络上前辈写的RAD类进行拨号。按窗口名称搜索窗体，并置当前窗体和向窗体发送按键的win API调用

            IntPtr hwnd = FindWindow(null, windowName); //查找窗体的句柄

　　2、固定IP接入，代理方式。刚开始有两个方法：a、发送http请求时封装代理IP；b、通过修改注册表方式修改本机IE浏览器代理地址，然后投票。后经测试b方法耗时时间长，而且不能多线程处理最后放弃采用a方法。

      a方法中采用异步调用方法，在最开始使用的是等待返回，后发现因网络延时的问题等待返回会造成程序假死状态，改为异步调用完成后回调方法。但这种方法无法调用控件，通过msdn帮助找到如何：对 Windows 窗体控件进行线程安全调用，控件多线程处理方法有三种，一种非线程安全方式，一种对 Windows 窗体控件进行线程安全调用，一种BackgroundWorker 进行的线程安全调调用。

      使用异步调用完成后回调方法

private delegate string NewTaskDelegate(string voteAdd, string proxyAdd);
//声明委托调用方法
        private static string vote(string voteAdd, string proxyAdd)
        {

            string url = voteAdd;
            try
            {
                WebRequest req = WebRequest.Create(url);
                // Create a new Uri object.
                if (proxyAdd != null || proxyAdd != "")
                {
                    Uri newUri = new Uri("http://" + proxyAdd);
                    WebProxy myProxy = new WebProxy();
                    myProxy.Address = newUri;
                    req.Proxy = myProxy;
                }

                WebResponse res = req.GetResponse();
                Stream receiveStream = res.GetResponseStream();
                Encoding encode = Encoding.GetEncoding("gb2312");
                StreamReader sr = new StreamReader(receiveStream, encode);
                char[] readbuffer = new char[256];
                int n = sr.Read(readbuffer, 0, 256);

                {
                    string str = new string(readbuffer, 0, n);
                    html += str;
                    n = sr.Read(readbuffer, 0, 256);
