大家帮我看看，还是关于检测MAC地址的问题，附带源码和编译时出现的错误。

你比较一下：

谢谢你 自在。一下子就检测到了我的网卡MAC地址！谢谢你们，楼上的各位朋友。

[constantine]

#include <nb30.h> 里面有定义NCB
很多地方（&;Adapter;）都多了点东西，改为（&Adapter;）
自己慢慢改就好了

还有一点就是我的网卡MAC地址是：00-E0-4C-C5-C8-2E而程序运行产生如下数据:
The NCBASTAT returned code is OX34
The NCBASTAT returned code is OX8
The number of FRMR frames received is 0
The number of FRMR frames transmitted is 0
不是网卡的MAC地址阿！！！
