我也不理解~
老师布置的这个题目
所以上网搜集些资料~找来找去就是这一段代码
都要崩溃了~

读取网卡的MAC地址 读取网卡的MAC地址 广东深圳 温卫江 在实际的应用系统中,我们往往会需要在程序运行时获取当前机器的网卡的MAC地址,以便作为某种标识之用,如控制程序的合法性等。下文介绍如何用Microsoft VisualC++ 6.0开发这样的程序。 这里采用的方法是通过Windows 9x/NT/Win2000中内置的NetApi32.DLL的功能来实现的。首先通过发送NCBENUM命令,获取网卡的数目和每张网卡的内部编号,然后对每个网卡标号发送NCBASTAT命令获取其MAC地址。注意:这里的网卡是指捆绑了NetBEIU协议的通信协议栈,可以在网卡的属性处查看到。 请运行VC++,打开一个新的工程,选择创建一个Win32 Console程序,然后按下文输入代码,并请参见其中的注释: #include "stdafx.h" #include <windows.h> #include <wincon.h> #include <stdlib.h> #include <stdio.h> #include <time.h> // 因为是通过NetAPI来获取网卡信息,所以需要包含其题头文件nb30.h #include <nb30.h> typedef struct _ASTAT_ { ADAPTER_STATUS adapt; NAME_BUFFER NameBuff [30]; } ASTAT, * PASTAT; ASTAT Adapter; // 定义一个存放返回网卡信息的变量 // 输入参数:lana_num为网卡编号,一般地,从0开始,但在Windows 2000中并不一定是连续分配的 void getmac_one (int lana_num) { NCB ncb; UCHAR uRetCode; memset( &ncb, 0, sizeof(ncb) ); ncb.ncb_command = NCBRESET; ncb.ncb_lana_num = lana_num // 指定网卡号 // 首先对选定的网卡发送一个NCBRESET命令,以便进行初始化 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 = lana_num; // 指定网卡号 strcpy((char *)ncb.ncb_callname,"*" ); ncb.ncb_buffer = (unsigned char *) &Adapter; // 指定返回的信息存放的变量 ncb.ncb_length = sizeof(Adapter); // 接着,可以发送NCBASTAT命令以获取网卡的信息 uRetCode = Netbios( &ncb ); printf( "The NCBASTAT return code is: 0x%x \n", uRetCode ); if ( uRetCode == 0 ) { // 把网卡MAC地址格式化成常用的16进制形式,如0010-A4E4-5802 printf( "The Ethernet Number[%d] is: %02X%02X-%02X%02X-%02X%02X\n", lana_num, 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] ); } } int main(int argc, char* argv[]) { NCB ncb; UCHAR uRetCode; LANA_ENUM lana_enum; memset( &ncb, 0, sizeof(ncb) ); ncb.ncb_command = NCBENUM; ncb.ncb_buffer = (unsigned char *) &lana_enum; ncb.ncb_length = sizeof(lana_enum); // 向网卡发送NCBENUM命令,以获取当前机器的网卡信息,如有多少个网卡、每张网卡的编号等 uRetCode = Netbios( &ncb ); printf( "The NCBENUM return code is: 0x%x \n", uRetCode ); if ( uRetCode == 0 ) { printf( "Ethernet Count is : %d\n\n", lana_enum.length); // 对每一张网卡,以其网卡编号为输入编号,获取其MAC地址 for ( int i=0; i<lana_enum.length; ++i) getmac_one( lana_enum.lana[i]); } return 0; } 此时,按F7编译,按F5运行即可。 这段代码可以直接嵌入相关的应用系统之中,或封装成.DLL或COM控件,以便可以在Visual Basic、Visual Foxpro、Power Builder或Delphi等其他程序中调用。

斑竹大哥可以给小弟指点一二吗~谢谢了
