Getting MAC Address of more than one NIC

See https://www.experts-exchange.com/questions/20671536/Unique-indentifiers-like-MAC-address-CPU-serial-number.html
Loop over AdapterList.length

Unfortunately not reliable on 95 or 98 (see http://msdn.microsoft.com/library/default.asp?url=/library/en-us/netbios/netbios_1l82.asp). Also relies on netbios being installed, which is not always the case.

Have a look at http://community.borland.com/article/0,1410,26040,00.html - ignore the first one as it is the same as above. Look at the 3rd one, SNMP, which appears to be the only reliable method. Only problem: C++.

In addition to Geoff post (that is the right way) at this point: 'Only problem: C++.'
Fortunatelly Project Jedi gives lot of solutions for Delphi developers too...so you can get the API SNMP.h translation for Delphi here ftp://delphi-jedi.org/api/snmp.zip (also example included) and look at the above Article for Delphi (french language but most useful than the C++ one) at http://www.iglooduhack.com/delphi_adresse_mac.php

This is a great routine for doing everything you want networks/adapters/and mac addresses.

do a search on yahoo for tcpmon12.zip . it was written by
Dirk Claessens  <dirkCL@pandora.be>  and uses tcp/ip to enumerate all network resources and information including mac addresses.

If you want to use netbios to do the same using netbios then search for getmacad.zip on yahoo

I don't have the original sites for the above but I can email the files if you have trouble finding them.

Hey JDuncan I searched for tcpmon12.zip and i didn´t find it. Can you send it to me please. My e-mail is "si0347429@univale.br"

my yahoo account keeps rejecting you email address - is it correct?

Yopu can upload the file from :-

http://81.137.231.48/upload/tcpmon.zip

Hey JDuncan do you know if it´s really possible to know which MAC is from what IP Address ? Because it shows it. But i´m no sure if it´s really possible. What do you think ???

Not sure I understand your question.

The same ethernet address(machine) can be bound to multiple network adapters

First I would like to thank you for the tcpmon file. What i´m trying to ask is. Each NIC has it´s own MAC address and IP. Can I trust  on the infomation tha it´s telling me which is for example: the NIC´s IP Address is 100.100.1.10 and it´s MAC Address is 00-01-29-52-04-A4.

JDuncan,
  Thank you. It was exactly what I needed man. I jus changed some things to do what I need. You helped me alot. Do you know if there´s anything like this one, but instead of getting the MAC, get the Video Card. I increased more 50 points for you.

Thanks, can you set the answer as accepted.

I think you can enumerater all system resources , i'll have a look

Jim Duncan

Thanx.

I found this , its not much it only gives you the monitor sizes.

Thes is a function EnumDisplayMonitors somewhere which may give more info.
The function EnumMonitors is more fore system monitors like print servioces etc.


 uses multimon;

  myMonitor : TMonitor;
  monInfo : PMonitorInfo;
begin
    new(monInfo);
    i:=Screen.MonitorCount;
    for i:=0 to Screen.MonitorCount-1 do begin
      myMonitor:=Screen.Monitors[i];
      GetMonitorInfo(myMonitor.Handle,monInfo);
      Showmessage(inttostr(monInfo.cbSize));
      Showmessage(inttostr(monInfo.rcWork.Right));
    end;
