在现有的资源管理器的窗口上打开里面的文件夹

https://social.msdn.microsoft.com/Forums/zh-CN/191612ac-21a6-4040-8a2d-e9c2e9797fbc/22914203093689036807201953072123454296163616428304316492970225?forum=visualcpluszhchs

这个方法是通过寻找本地资源管理器的窗口句柄，再去找地址栏编辑框的句柄，然后地址栏末端加上文件夹名字，最后发送回车消息，完成操作。似乎有几个步骤可以省略，还需要回头完善一下，例如组合框的下拉会被点击，这个操作不知道能不能省略或者让点击事件不那么明显，我禁用了以后就不能执行了，感觉还可以优化一下。因为那一段代码抄的一位大佬的代码，所以没去细细琢磨下每个类和消息产生的作用，但整体思路是正确的。
