• QT---Native Wifi functions 应用(WiFi有密码连接)

    实现功能
        无线网卡列表
        无线热点扫面
        无线连接（有密码，配置文件连接方式）
        无线断开
        重命名本地无线名（两种方式）
        删除无线配置文件
        开启和关闭无线网卡
    Native Wifi 简介
        是提供给软件开发者来开发windows 无线管理的一系列API。编程人员可以通过这些函数来进行相关的无线管理，当然我们还可以通过netsh终端命令来管理，这对于非编程人员就可以简单的实现，具体可以查阅相关资料去了解。
        API如下：
    无线的连接相关知识
        从windows的无线网络属性设置窗口来对比，在API编程中，同样有个配置文件来设置这些属性的，那就是profile文件，通过编写xml文件来设置相关属性。

    WLAN_profile Schema Elements [xml配置文件编写格式]：

        

    Wireless Profile Samples[无线配置文件例程]

        例如常见的路由器，安全类型为WPA2-PSK的xml配置文件如下（有密码）：
        
    <?xml version="1.0" encoding="US-ASCII"?>
    <WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1">

            <SSID>
