怎么得到网卡的物理地址？netbios() 函数并不能成功！

[reeching]

看了很多读取物理地址的读法，都是用UCHAR Netbios( PNCB pncb );函数，但是当网线断开了，她就返回0x23，不能活得网卡物理地址，怎么办？

GetMacAddress
Include nb30.h and link with netapi32.lib.
typedef struct _ASTAT_
{
ADAPTER_STATUS adapt;
NAME_BUFFER NameBuff[30];
} ASTAT, * PASTAT;


CString GetMacAddress(CString sNetBiosName)
{
ASTAT Adapter;

NCB ncb;
UCHAR uRetCode;

memset(&ncb, 0, sizeof(ncb));
ncb.ncb_command = NCBRESET;
ncb.ncb_lana_num = 0;

uRetCode = Netbios(&ncb);

memset(&ncb, 0, sizeof(ncb));
ncb.ncb_command = NCBASTAT;
ncb.ncb_lana_num = 0;

sNetBiosName.MakeUpper();

FillMemory(ncb.ncb_callname, NCBNAMSZ - 1, 0x20);

strcpy((char *)ncb.ncb_callname, (LPCTSTR) sNetBiosName);

ncb.ncb_callname[sNetBiosName.GetLength()] = 0x20;
ncb.ncb_callname[NCBNAMSZ] = 0x0;

ncb.ncb_buffer = (unsigned char *) &Adapter;
ncb.ncb_length = sizeof(Adapter);

uRetCode = Netbios(&ncb);

CString sMacAddress;

if (uRetCode == 0)
{
sMacAddress.Format(_T("%02x%02x%02x%02x%02x%02x"),
Adapter.adapt.adapter_address[0],
Adapter.adapt.adapter_address[1],
Adapter.adapt.adapter_address[2],
Adapter.adapt.adapter_address[3],
Adapter.adapt.adapter_address[4],
Adapter.adapt.adapter_address[5]);
}
return sMacAddress;
}

如果还有问题，请发EMail: [e-mail]。可以给你一个例程。

GetAdaptersinfo的方法

//get adapter info

if(dwReturn != NO_ERROR)
{
delete pAdapter;

如果回答得好，请给分

其实还有一种终级的方法
如果网卡有EEPROM,MAC address就记录在里面
所以我们就可以从里面读出我们想要的东西，
甚至我们还可以更改这个全球唯一的MAC地址

shaohua(美女?我抱!警察?我闪!我是流氓我怕谁)
的方法好像不行！
lj_csdn(大笨蛋) netbios方法 也一样，不过 而uuid的方法还可以，snmp的方法：还没有试过。看来你手头的资料很全哦，thanks

fchwfchw(孤独的人是可耻的) GetAdaptersinfo的方法，还可以，但是#include <Iphlpapi.h>这个文件一般的windows上是没有的，微软好像没有将Iphlpapi.h所在的开发包开放出来哦。
谢谢大家！
