Question :
How can I get network card unique ID ?
Answer :
function _SysGetNICAddress: string;
var
Tmp : TGUID;
tmpstr : string;
newstr : string;
cnt : integer;
begin
try
CoCreateGuid(Tmp);
tmpstr := GuidToString(Tmp);
tmpstr := Copy(tmpstr, Length(tmpstr)-12, 12);
for cnt := 1 to 5 do
newstr := newstr + copy(tmpstr, cnt*2-1, 2) + '-';
newstr := newstr + copy(tmpstr, 11, 2);
except
newstr := '';
end;
Result := newstr;
end;
如是指物理号，在我的网子上有篇帖子，有两种方法（radsworld.myrice.com)
请搜索“网卡”或者“MAC”即可找到答案。

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 //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;
谢谢楼上兄。
