鼠标的简单远程控制(原创)

思想:通过构建一个结构包,包里有鼠标的状态,鼠标的位置,在模拟端根据包信息模拟鼠标的动作,
实现远程鼠标的控制.
几个环节:
1:发送端发出的鼠标位置是逻辑坐标.
2:模拟端必须把收到的包里的鼠标位置,转换为屏幕坐标的位置,再用SetCursorPos实现坐标移动.
用到的函数及作用:
ScreenToClient 屏幕坐标转换成逻辑坐标
ClientToScreen 逻辑坐标转换成屏幕坐标
SetCursorPos 设置鼠标的屏幕位置
mouse_event 模拟鼠标的动作
ClipCursor 圈定鼠标的活动范围
GetWindowRec 获得对象大小
SetCapture 捕获鼠标信息
ReleaseCapture 取消捕获鼠标信息
一下代码可以实现远程的鼠标移动,起到抛砖引玉作用,读者可以自行添加其他功能
