oops, I did it again.
Errors in my code must be:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
IP_ADAPTER_INFO info;
unsigned long len=0;
int n;
AnsiString m_macaddress;

if(GetAdaptersInfo(&info,&len) == ERROR_BUFFER_OVERFLOW)
                n=len/sizeof(info);
   else
      {
       ShowMessage("No data or another error");
       Application->Terminate();
       return;
      }

if(n <= 0)
      {
       ShowMessage("Something bad !!!");
       Application->Terminate();
       return;
      }

PIP_ADAPTER_INFO pinfox=new  IP_ADAPTER_INFO[n];

if(GetAdaptersInfo(pinfox,&len) == ERROR_SUCCESS)
for(int i=0 ; i < n; ++i)
  {

                 TVarRec v[] = {pinfox[i].Address[0], pinfox[i].Address[1], pinfox[i].Address[2],
                 pinfox[i].Address[3],pinfox[i].Address[4],pinfox[i].Address[5]};
                 m_macaddress=Format("%2.2X:%2.2X:%2.2X:%2.2X:%2.2X:%2.2X",v,5);
                 ShowMessage("Adapter num. "+IntToStr(i)+ "\n MAC address "+m_macaddress);
  }
  else ShowMessage("Error !!!");

 delete [] pinfox;

}

Vladimir.
