取得网卡地址

[byybyybyy]

win2000,vc6.0控制台做了一个获取本机网卡的小程序。遇到困难，请求帮助。我是新手

我没分了，可怜，多谢了！

源码：

#include <windows.h>
#include <wincon.h>
#include <stdlib.h>
#include <stdio.h>
#include <time.h>
#include <string.h>

typedef struct _ASTAT_
{
ADAPTER_STATUS adapt;
NAME_BUFFER NameBuff [30];
}ASTAT, * PASTAT;

ASTAT Adapter;

void main (void)
{
NCB ncb;
UCHAR uRetCode;
char NetName[50];

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

uRetCode = Netbios( &ncb );
printf( "The NCBRESET return code is: 0x%x \n", uRetCode );

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

strcpy( ncb.ncb_callname, "* " );
ncb.ncb_buffer = (char *)&Adapter;
ncb.ncb_length = sizeof(Adapter);

uRetCode = Netbios( &ncb );
printf( "The NCBASTAT return code is: 0x%x \n", uRetCode );
if ( uRetCode == 0 )
{
printf( "The Ethernet Number is: %02x%02x%02x%02x%02x%02x\n",
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] );
}
}



错误信息：

}

这样就ok了

经过调试发现楼上的代码里的char NetName[50]好象多余。
删除后就可以了。调试环境：win2000p+vc++6.0

}
}
最后被忘了还要链一个库文件：netapi32.lib

只是strcpy这个函数的参数问题，
换一下参数类型，
如果不行的话就用sprintf吧。

我是这样用的：strcpy((char *)ncb.ncb_callname, (LPCTSTR) sNetBiosName);
