在xpe下获取mac地址失败，但是在xp下是正常的，帮我看一下

[银点]

AnsiString __fastcall TMainForm::GetLocalMac()
{
    typedef struct _ASTAT
    {
        ADAPTER_STATUS adapt;
        NAME_BUFFER NameBuffer[30];
    }ASTAT, *PASTAT;

    ASTAT Adapter;
    NCB ncb;
    UCHAR uRetCode;
    memset(&ncb,0,sizeof(ncb));
    ncb.ncb_command=NCBRESET;
    ncb.ncb_lana_num=0;
    Netbios(&ncb);
    memset(&ncb,0,sizeof(ncb));
    ncb.ncb_command=NCBASTAT;
    ncb.ncb_lana_num=0;
    strcpy((char *)ncb.ncb_callname,"* ");
    ncb.ncb_buffer=(unsigned char *) &Adapter;
    ncb.ncb_length=sizeof(Adapter);
    uRetCode=Netbios(&ncb);
    AnsiString str="";
    if(uRetCode == 0)
    {
        str.printf("%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] );
        return str;
    }
    else
    {
        return "MAC Error!";
    }
}

netbios反回值是0x23，指ncb.ncb_lana_num=0无效

但是此函数在xp下都是正常的，在XPE下失败

试试这段代码可以么，没有xpe下执行过，我也不知道结果

//----------------------------------------------------------------
// Fetches the MAC address and prints it
 DWORD GetMACaddress(TStringList *MacList)
{
  if(MacList == NULL) return -1;
  DWORD MACaddress = 0;
  IP_ADAPTER_INFO AdapterInfo[16];       // Allocate information
                                         // for up to 16 NICs
  DWORD dwBufLen = sizeof(AdapterInfo);  // Save memory size of buffer

  DWORD dwStatus = GetAdaptersInfo(      // Call GetAdapterInfo
			AdapterInfo,                 // [out] buffer to receive data
			&dwBufLen);                  // [in] size of receive data buffer
  assert(dwStatus == ERROR_SUCCESS);  // Verify return value is
                                      // valid, no buffer overflow

  PIP_ADAPTER_INFO pAdapterInfo = AdapterInfo; // Contains pointer to
                                               // current adapter info
  do {
	if (MACaddress == 0)
		MACaddress = pAdapterInfo->Address [5] + pAdapterInfo->Address [4] * 256 + 
					pAdapterInfo->Address [3] * 256 * 256 + 
					pAdapterInfo->Address [2] * 256 * 256 * 256;
    PrintMACaddress(pAdapterInfo->Address,MacList); // Print MAC address
    pAdapterInfo = pAdapterInfo->Next;    // Progress through linked list
  }
  while(pAdapterInfo);                    // Terminate if last adapter
  
  return MACaddress;
}

[zzbinfo]

static void PrintMACaddress(unsigned char MACData[],TStringList *MacList)
{
      char macdate[256];
        if(MacList == NULL) return ;
	sprintf(macdate,"%02X%02X%02X%02X%02X%02X",MACData[0], MACData[1],
			   MACData[2], MACData[3], MACData[4], MACData[5]);
        MacList->Add(AnsiString(macdate));

}

妖哥，帮忙把它移到技术区去吧

十分感谢，根据你的代码，我查了MSDN中GetAdaptersInfo用法，问题解决 了

我明明发在基础里，怎么成了水版贴了?

眼花了吧。可没人动过你的帖子。
