一、流程

1、调用Window接口模拟鼠标，键盘事件

POINT point;
LPPOINT lpppoint = &point;
GetCursorPos(lpppoint);//获取鼠标位置
SetCursorPos(point.x, point.y);//设置鼠标位置//鼠标左键按下
mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, point.x, point.y, 0, 0);//获取键盘状态
short s = GetKeyState(VK_SHIFT);//按键按下，注意：字母只有大写生效且会转换为小写，大写：先按shift再写字母，或按下capital键
//微软码表：https://learn.microsoft.com/zh-cn/windows/win32/inputdev/virtual-key-codes
keybd_event(VK_SHIFT, 0, 0, 0);
keybd_event(VK_SHIFT, 0, KEYEVENTF_KEYUP, 0);

2、嵌入外部程序

使用VS自带的调用Window接口获取外部程序

打开VS -》工具-》Spy++(+)

 键盘【Ctrl + F】-》查找窗口-》将工具拖拽到已打开的程序窗口，获取到标题、类，创建窗口时使用

3、将鼠标键盘事件响应到具体坐标位置

通过与定时器配合使用可以实现一些固定的自动化操作(*^▽^*)
