[WM][转]PPC中如何找到正在使用中的网络(源代码)
本文转自: 一起飞翔的Blog,原文见这里:http://17feixiang.com/article/jishu/83.htm
《PPC中如何判断网络已经连接或者断开》中已经说明了如何判断PPC的网络是否连接和断开,本篇文章讲讲如何枚举出当前的网络状态,并找到正在使用中的网络。一个比较简单的应用就是当接到系统连接到网络的通知之后,需要判断是免费网络还是收费网络,之后再作相应处理。一般免费网络就是WIFI和ActiveSync,收费网络就是CMNET和CMWAP。下面的代码就来判断当前连接的网络究竟是什么网络,要做到这一点,需要使用一个函数ConnMgrQueryDetailedStatus,这个函数可以得到网络的详细信息,从他的dwType中可得到网络的类别,dwSubtype可以知道具体的网络类型。具体代码如下,写的已经是比较详细了,如有问题可以在17feixiang.com上留言。

PS:
很可惜,在MSDN里面没有这个API,需要看头文件#include<connmgr_status.h>,以及Windows Mobile Document才能找到.
