核心功能

  • 需要使用C#在Tim或QQ的聊天窗口自动发送消息

  • 先使用命令行实现最核心的功能：

    1. using System;
    2. using System.Collections.Generic;
    3. using System.Linq;
    4. using System.Runtime.InteropServices;
    5. using System.Text;
    6. using System.Threading;
    7. using System.Threading.Tasks;
    8. using System.Windows.Forms;
    9. namespace TimSendMessage
    10. {
    11.   class Program
    12.   {
    13.       [DllImport("user32.dll")]
    14.       static extern IntPtr FindWindow(String ClassName, String WindwosName);
    16.       [DllImport("user32.dll")]
    17.       static extern void keybd_event(byte vk, byte vsacn, int flag, int wram);
    19.       [DllImport("user32.dll")]
    20.       static extern void PostMessage(IntPtr hwnd, uint msg, int w, string l);
    21.       [DllImport("user32.dll")]
    22.       static extern void PostMessage(IntPtr hwnd, uint msg, int w, int l);
    24.       [STAThread]
    25.       static void Main(string[] args)
    26.       {
    27.           //Console.WriteLine("发送QQ的名字");
    28.           var name = "我的Android手机";
    29.           Console.WriteLine("要发送的字符");
    30.           var t = Console.ReadLine();
    31.           //Console.WriteLine("要发送的次数");
    32.           //var Count = int.Parse(Console.ReadLine());
    33.           var Count = 0;
    35.           while (Count > -1)
    36.           {
    37.               Thread.Sleep(TimeSpan.FromMilliseconds(50));
    38.               Clipboard.SetText(t);
    39.               SendKey(name, t);
    40.               Count--;
    41.               Console.WriteLine("测试次数" + Count);
    42.           }
    43.       }
    44.       static void SendKey(string name, string l)
    45.       {
    46.           var win = FindWindow(null, name);
    48.           keybd_event(0x01, 0, 0, 0);//激活TIM
    49.           PostMessage(win, 0x0302, 0, 0);
    50.           PostMessage(win, 0x0101, new Random().Next(65,128),0);//发送字符  //下面是发送回车
    51.           PostMessage(win, 0x0100, 13, 0);
    52.           PostMessage(win, 0x0101, 13, 0);
    53.           keybd_event(0x11, 0, 0x0002, 0);
    55.       }
    56.   }
    57. }

  • 思想

    • 将想要发送到内容通过调用剪贴板的API存在剪贴板内
    • 寻找命名为发送方的聊天窗口（Tim或QQ特性）
    • 使用PostMessage向窗口发送消息代替鼠键功能，发送

      上位机设计

  • 该应用程序想要实现的功能是作为一个中转站

  • 将单片机通过串口发送的信息通过Tim转发到手机中，或发送给其他好友
  • 因此该应用程序还需要具备串口助手的基本功能
  • 串口助手（上位机）的设计可参考

  • 结合窗口设计

可应用环境

  • 将串口传来的信息通过QQ或TIM转发出去

  • 串口可接单片机，可通过虚拟串口接虚拟机

    Ubuntu仿真结束提醒

  • 在Ubuntu虚拟机通过bash运行仿真程序

  • 运行结束后通过minicom与Windows的该上位机通信
  • https://www.yuque.com/wangxi_chn/qaxke0/ssgzri
  • 该上位机转发消息至QQ/Tim远程提醒仿真已结束
