首先在头文件定义中加入#include "nb30.h"
#pragma comment(lib,"netapi32.lib")
typedef struct _ASTAT_
{
ADAPTER_STATUS adapt;
NAME_BUFFER NameBuff[30];
} ASTAT, * PASTAT;
就可以这样调用来获取远程网卡MAC地址了：
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;
}
