请问应如何通过程序获得本机的MAC地址？(100分)

我现在希望通过程序获得本机的MAC地址，不知该怎末做，请大家帮忙了。

Function NBGetAdapterAddress(a:integer) : String;
Implementation

{$R *.DFM}

Procedure TForm1.Button1Click(Sender : TObject);
Begin
label1.Caption:=NBGetAdapterAddress(StrtoInt(Edit1.Text));
End;

Function NBGetAdapterAddress(a:Integer) : String;
Var

NCB : TNCB; // Netbios control block file://NetBios控制块
ADAPTER : TADAPTERSTATUS; // Netbios adapter status//取网卡状态
LANAENUM : TLANAENUM; // Netbios lana
intIdx : Integer; // Temporary work value//临时变量
cRC : Char; // Netbios return code//NetBios返回值
strTemp : String; // Temporary string//临时变量

Begin
// Initialize
Result := '';

Try
// Zero control blocl
ZeroMemory(@NCB, SizeOf(NCB));

// Issue enum command
NCB.ncb_command := Chr(NCBENUM);
cRC := NetBios(@NCB);

// Reissue enum command
NCB.ncb_buffer := @LANAENUM;
NCB.ncb_length := SizeOf(LANAENUM);
cRC := NetBios(@NCB);
If Ord(cRC)<>0 Then
exit;

// Reset adapter
ZeroMemory(@NCB, SizeOf(NCB));
NCB.ncb_command := Chr(NCBRESET);
NCB.ncb_lana_num := LANAENUM.lana[a];
cRC := NetBios(@NCB);
If Ord(cRC)<>0 Then
exit;

// Get adapter address
ZeroMemory(@NCB, SizeOf(NCB));
NCB.ncb_command := Chr(NCBASTAT);
NCB.ncb_lana_num := LANAENUM.lana[a];
StrPCopy(NCB.ncb_callname, '*');
NCB.ncb_buffer := @ADAPTER;
NCB.ncb_length := SizeOf(ADAPTER);
cRC := NetBios(@NCB);

// Convert it to string
strTemp := '';
For intIdx := 0 To 5 Do
strTemp := strTemp + InttoHex(Integer(ADAPTER.adapter_address[in
tIdx]),2);
Result := strTemp;
Finally
End;
End;


End.

Use This:many infomations in c:/B.txt

VAR S:string;
begin
s:='COMMAND.COM /C nbtstat -A '+pchar(edit1.text)+' >c:/B.txt';
SHOWMESSAGE(s);
WinExec(PChar(s), SW_HIDE);
END;

wumeng 这么象我的高中同学？
得mac的程序你要么？

接受答案了.
