c++ WlanAPI 承载网络 连接无线网络

最近在玩树莓派，烧录的也是win10  IOT 系统，然后想弄一个界面可以手动设置wifi热点，所以找了找windows的wlanAPI.

然后发现网上很多关于 保存了密码的无线网络 的连接方法，如：http://blog.csdn.net/lincyang/article/details/34430939这位仁兄的文章，
但是如何设置热点的几乎没有！

所以只能自己弄，麻烦的要命，其实在电脑上是不需要这么麻烦的用代码来实现的，直接用dos命令就能搞定，这只是个人的爱好和需要。dos命令就不介绍了百度一大堆！

要用的可以直接拷贝，可以编译直接使用，当然这是个demo，看着不舒服的自己改改哈！
