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) { bool isWinExist1 = isWindowsExistSleep("远程桌面连接", "连接(&N)", 3000); if (isWinExist1) { Thread.Sleep(20); API.OpenIcon(hwnd); API.SetForegroundWindow(hwnd); Thread.Sleep(20); SendKeys.SendWait("%n"); //Shift + Ctrl ^ Alt % //API.keybd_event((int)Keys.Alt, API.MapVirtualKeyA((int)Keys.Alt, 0), 0, 0); //API.keybd_event((int)Keys.N, API.MapVirtualKeyA((int)Keys.N, 0), 0, 0); //API.keybd_event((int)Keys.N, API.MapVirtualKeyA((int)Keys.N, 0), 2, 0); //API.keybd_event((int)Keys.Alt, API.MapVirtualKeyA((int)Keys.Alt, 0), 2, 0); Thread.Sleep(1000); } } isWinExist2 = isWindowsExistSleep("远程桌面连接", "是(&Y)", 5000); if (isWinExist2) { Thread.Sleep(20); API.OpenIcon(hwnd); API.SetForegroundWindow(hwnd); Thread.Sleep(20); SendKeys.SendWait("%y"); //Shift + Ctrl ^ Alt % //API.keybd_event((int)Keys.Alt, API.MapVirtualKeyA((int)Keys.Alt, 0), 0, 0); //API.keybd_event((int)Keys.Y, API.MapVirtualKeyA((int)Keys.Y, 0), 0, 0); //API.keybd_event((int)Keys.Y, API.MapVirtualKeyA((int)Keys.Y, 0), 2, 0); //API.keybd_event((int)Keys.Alt, API.MapVirtualKeyA((int)Keys.Alt, 0), 2, 0); Thread.Sleep(20); } bool isWinDesk = isWindowsExistSleep($"incam专用 - {address} - 远程桌面连接", "", 10000); isOK = isWinDesk; if (isWinDesk) API.ShowWindow(hwnd, 2); return isOK; }
