这是基于DirectShow的虚拟摄像头驱动源代码工程，此工程采用从零开发，采用非常原始的方法实现COM基础组件和IBaseFilter，IPin等接口功能。
不依赖DSHOW的SDK库就可以编译运行，本代码工程使用VS2015编译。
如果你不喜欢，或者不想去了解DirectShow的工作原理，大可不必理会我这种比较“疯狂”的做法，也不必下载我的这份代码给你平添无谓的烦恼。
source目录是工程目录，bin是已经编译好的dll，可以调用register.bat注册，调用unregister.bat注销.注册成功后，使用DirectShow框架的程序就可以发现并访问这个虚拟摄像头，比如QQ，amcap等。
本工程详细原理介绍，请看如下链接：https://blog.csdn.net/fanxiushu/article/details/79830750Fanxiushu2018

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
