虚心求教，求一个可通用的获取MAC地址的代码

[jixiaohai]

分不多。。虚心求教各位delphi前辈如何写一个可以通用的 获取MAC地址的方法?
翻遍网络了。。网络上最常用的几种写法。全部都测试了。
包括用winsock。nb30。读取注册表 三种方法全都试过。可是在客户公司里。居然仅仅5台电脑。（同一次购买。所以cpu。硬盘。主板序列号全部一样。所以无法用获取这三个值作为判断用）
分不多，还望各位前辈能指点一下到底如何才能通用的代码获取MAC地址呢？跪求啦

用winpcap试试 我现在就在用它，挺好用的！

DELPHI编程可以实现读取MAC地址
uses
WinSock;

Function sendarp(ipaddr: ulong; temp: dword; ulmacaddr: pointer;
ulmacaddrleng: pointer): dword; StdCall;
External 'Iphlpapi.dll' Name 'SendARP';

procedure TForm1.Button1Click(Sender: TObject);
var
myip: ulong;
mymac: array [0 .. 5] of byte;
mymaclength: ulong;
r: integer;
begin
myip := inet_addr(PChar('192.168.6.180'));
mymaclength := length(mymac);
r := sendarp(myip, 0, @mymac, @mymaclength);
label1.caption := 'errorcode:' + inttostr(r);
label2.caption := format('%2.2x:%2.2x:%2.2x:%2.2x:%2.2x:%2.2x',
[mymac[0], mymac[1], mymac[2], mymac[3], mymac[4], mymac[5]]);
end;

可否给个实例看下。还没有用过winpcap。。不知如何入手

这个我试过了。有些电脑上死活就是获取不到值

[babydog01]

网卡的MAC肯定是可以改的，建议还是尽量用硬件的ID号来做。

但读取只能对部门硬盘有效，请参阅：

不可能的，要不你是买了假货了，哈哈........

这个东西还真是一样的。同一批次生产出来的。所获得的值都是一样的。假货？国内又能力仿cpu这些东西了？

[babydog01]

硬件的ID肯定是唯一的，不可修改的，您读的肯定不是硬件ID....

网卡的 MAC 倒是可以修改的...

那可能是我代码问题。请指点一下。下面的代码获得的是什么值？是cpuid还是什么东西。mac获取不是很准确。通用性不行。有些方法这个电脑可以获得。另一个电脑就获得不了。有些就正好反过来

function GetCpuId:longint;assembler;register;
var
temp:longint;
begin
asm
PUSH EBX
PUSH EDI
MOV EDI,EAX
MOV EAX,1
DW $A20F
MOV TEMP,EDX
POP EDI
POP EBX
end;
result:=temp;
end;

第一种可以获得mac但是通用性还没测试。第二种完全获得不到东西。。看来也没人会来回答问题了。分就给你吧
