One way:
void GetMacAddress()

{

	// Ensure buffer size is big enough to hold the address

	TCHAR szBuffer[18];

	DWORD dwSize = 18;
 

	NCB ncb;

	LANA_ENUM lenum;

	UCHAR uMACAddress[6];

	int i;

	int iLEnumCnt = 1;

	UCHAR uRASAdapterAddress[6] = { 0x44, 0x45, 0x53, 0x54, 0x0, 0x0 };  // DEST
 

	::ZeroMemory(&ncb, sizeof(NCB));

	::ZeroMemory(&lenum, sizeof(lenum));
 

        // Helper function using GetVersionEx()

	if(IsOSPlatformNT())

	{

		// NT or better supports adapter enumeration

		ncb.ncb_command = NCBENUM;

		ncb.ncb_buffer = (UCHAR *)&lenum;

		ncb.ncb_length = sizeof(lenum);
 

		UCHAR uRet = Netbios(&ncb);
 

		if(uRet == NRC_GOODRET) 

		{

			iLEnumCnt = (int)lenum.length;

		}

	}

	else

	{

		// Can't do enumeration, so we'll pretend and query the first adapter only

		lenum.length = (UCHAR)iLEnumCnt;
 

		for(i=0; i<iLEnumCnt; ++i)

			lenum.lana[i] = (UCHAR)i;

	}
 

	for(i = 0; i < iLEnumCnt; ++i) 

	{

		if(ResetAdapter(lenum.lana[i]))

		{

			if (GetAdapterStatus(lenum.lana[i], uMACAddress))

			{

				// ignore RAS adapter address, we want MAC

				if (memcmp(uMACAddress, uRASAdapterAddress, 6) != 0)

				{

					wsprintf(szBuffer, "%02X:%02X:%02X:%02X:%02X:%02X", (int)uMACAddress[0], (int)uMACAddress[1], (int)uMACAddress[2], (int)uMACAddress[3], (int)uMACAddress[4], (int)uMACAddress[5]);
 

				}

			}

		}

	}

}
 

#include <Nb30.h>

	if(uRet == NRC_GOODRET)

		return TRUE;
 

	::SetLastError(uRet);

	return FALSE;

}

My Way:

//kidding...Khalid Shaikh Way:

I executed under V.S. 2008 and OK!

// GetMACUuid.cpp : Defines the entry point for the console application.

//

// Author:	Khalid Shaikh [Shake@ShakeNet.com]

// Date:	April 5th, 2002

//

// This program fetches the MAC address of the localhost by creating a UUID

// and obtaining the IP address through that

//

// Prewindows 2000 one should replace the function below 

//			UuidCreateSequential with UuidCreate

// Microsoft decided that it was not wise to put the MAC address in the UUID

// hence changed the algorithm in Windows 2000 and later to not include it.

//

// Supported in Windows NT/2000/XP

// Supported in Windows 95/98/Me

//

// Supports single NIC card.
 

#include "stdafx.h"

#include <Windows.h>

#include <rpc.h>

#include <rpcdce.h>

#pragma comment(lib, "rpcrt4.lib")
 

// Prints the MAC address stored in a 6 byte array to stdout

static void PrintMACaddress(unsigned char MACData[])

{

	printf("MAC Address: %02X-%02X-%02X-%02X-%02X-%02X\n", 

		MACData[0], MACData[1], MACData[2], MACData[3], MACData[4], MACData[5]);

}
 

// Fetches the MAC address and prints it

static void GetMACaddress(void)

{

	unsigned char MACData[6];
 

	UUID uuid;

    UuidCreateSequential( &uuid );				// Ask OS to create UUID
 

    for (int i=2; i<8; i++)						// Bytes 2 through 7 inclusive are MAC address

		MACData[i - 2] = uuid.Data4[i];
 

	PrintMACaddress(MACData);					// Print MAC address

}
 

int _tmain(int argc, _TCHAR* argv[])

{

	GetMACaddress();							// Obtain MAC address of adapters
 

	return 0;

Hey, could you send your modified code?

Sorry jazzIIIlove:

I had some bussy time here.
I just made a class like:

//---------------------------------------------------------------------------

#ifndef MacH
#define MacH
#include <sstream.h>

//---------------------------------------------------------------------------
class Mac {
public:
   string mac();
};
#endif

And modified your code to get the string, as i have only one mac address i used a string:

#include "Mac.h"

#include <windows.h>
#include <wincon.h>
#include <stdlib.h>
#include <stdio.h>
#include <time.h>

typedef struct _ASTAT_   {
  ADAPTER_STATUS adapt;
  NAME_BUFFER    NameBuff [30];

} ASTAT, * PASTAT;

ASTAT Adapter;

string Mac::mac()  {
      NCB Ncb;
      UCHAR uRetCode;
      char NetName[50];
      LANA_ENUM   lenum;
      int      i;
      char mac_addr[12];
      string macy;
      string mac_address;
     
      memset( &Ncb, 0, sizeof(Ncb) );
      Ncb.ncb_command = NCBENUM;
      Ncb.ncb_buffer = (UCHAR *)&lenum;
      Ncb.ncb_length = sizeof(lenum);
      uRetCode = Netbios( &Ncb );
      printf( "The NCBENUM return code is: 0x%x \n", uRetCode );
      int n = lenum.length;
      for(i=0; i < n ;i++)
      {


          memset( &Ncb, 0, sizeof(Ncb) );
          Ncb.ncb_command = NCBRESET;
          Ncb.ncb_lana_num = lenum.lana[i];
 
          uRetCode = Netbios( &Ncb );
          printf( "The NCBRESET on LANA %d return code is: 0x%x \n",
                  lenum.lana[i], uRetCode );
 
          memset( &Ncb, 0, sizeof (Ncb) );
          Ncb.ncb_command = NCBASTAT;
          Ncb.ncb_lana_num = lenum.lana[i];
 
          strcpy( Ncb.ncb_callname,  "*               " );
          Ncb.ncb_buffer = (char *) &Adapter;
          Ncb.ncb_length = sizeof(Adapter);
 
          uRetCode = Netbios( &Ncb );
          printf( "The NCBASTAT on LANA %d return code is: 0x%x \n",
                  lenum.lana[i], uRetCode );
          if ( uRetCode == 0 )  {
             sprintf( mac_addr,"%02x%02x%02x%02x%02x%02x",
                  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] );
          }
          macy = mac_addr;
       }

  return macy;

}
 
then you just instanciate the object on a standard window form to get the string value from the class just described!!
like

string macaddress;
Mac mac;
macaddress = mac.mac();

Thanks for your help!
