我是靠谱客的博主爱笑小蚂蚁，这篇文章主要介绍windows下控制鼠标移动和点击的c语言实现，现在分享给大家，希望可以做个参考。

最近由于老婆工作上有抢单的需求，需要一款自动处理鼠标事件的小程序，之前也没有编写过直接操作系统资源的程序，所以一开始是

打算用python来写，毕竟脚本语言实现起来方便，可是后来实施起来发现需要安装很多库，而且有些库就是怎么都安装不上大哭，于是就放

弃了。后来查阅了一些资料，看了很多别人写的博客，发现用C#和mfc实现的比较多，mfc这东西我本身就不感兴趣，果断放弃，倒是C#吸

引了我，但是发现新买的电脑还没有装Visual Studio，而且我又比较懒，只能放弃了，最后决定用VC控制台程序来实现。其实这个程序实现

的关键就是调用windows api中的user32.dll中的两个函数就搞定了，这里要特别感谢一篇不知作者的文章，给了我提示，文章的链接是
