PCB 一键远程桌面+RDP文件生成

最近在写个内网INCAM内网授权工具中，在服务端监听客户端请求后，后台自动处理客户端请求并远程客户端

这里记录3个点。

一.运行RDP文件后，正常会有下图2个弹窗，怎么可以关闭这2个弹窗呢，

通过模拟按键ALT+N，ALT+Y

二.客户端与服务端状态如何控制的，客户端发起请求：状态流程图

三.实现部份代码：

 private bool DeskLink(string IPAddress, string Domain, string UserName, string Password)
        {
            bool isOK = false;
            DelMstsc();
            string address = IPAddress;
            string domain = Domain;
            string username = UserName;
            string password = Password;
            string filename = "incam专用.rdp";
            var TemplateStr = RDPdemo.Properties.Resources.TemplateRDP;//获取RDP模板字符串
            var pwstr = BitConverter.ToString(DataProtection.ProtectData(Encoding.Unicode.GetBytes(password), ""));
            pwstr = pwstr.Replace("-", "");
            var NewStr = TemplateStr.Replace("{#domain}", domain).Replace("{#address}", address).Replace("{#username}", username).Replace("{#password}", pwstr);
            StreamWriter sw = new StreamWriter(filename);
            sw.Write(NewStr);
            sw.Close();
            ProcCmd("mstsc " + filename);
            Thread.Sleep(1000);
            bool isWinExist2 = isWindowsExistSleep("远程桌面连接", "是(&Y)", 200);
            if (!isWinExist2)
