The only line has been added : cout << "MY INFO : AdapterList.length = " << static_cast(AdapterList.length) << endl; We can see that AdapterList.length == 0. So, we can't get MAC address. Is something wrong ? P.S.S. The program was running while I was working offline. Is it essential for this program ? ======= C++ Code : BEGIN ========= // File x2.cpp #include #include #include #include #include #include using namespace std; bool GetAdapterInfo(int nAdapterNum, string & sMAC) { // Reset the LAN adapter so that we can begin querying it NCB Ncb; memset(&Ncb, 0, sizeof(Ncb)); Ncb.ncb_command = NCBRESET; Ncb.ncb_lana_num = nAdapterNum; if (Netbios(&Ncb) != NRC_GOODRET) { char acTemp[80]; ostrstream outs(acTemp, sizeof(acTemp)); outs << "error " << Ncb.ncb_retcode << " on reset" << ends; sMAC = acTemp; return false; } // Prepare to get the adapter status block memset(&Ncb, 0, sizeof(Ncb)); Ncb.ncb_command = NCBASTAT; Ncb.ncb_lana_num = nAdapterNum; strcpy((char *) Ncb.ncb_callname, "*"); struct ASTAT { ADAPTER_STATUS adapt; NAME_BUFFER NameBuff[30]; } Adapter; memset(&Adapter, 0, sizeof(Adapter)); Ncb.ncb_buffer = (unsigned char *)&Adapter; Ncb.ncb_length = sizeof(Adapter); // Get the adapter's info and, if this works, return it in standard, // colon-delimited form. if (Netbios(&Ncb) == 0) { char acMAC[18]; sprintf(acMAC, "%02X:%02X:%02X:%02X:%02X:%02X", int (Adapter.adapt.adapter_address[0]), int (Adapter.adapt.adapter_address[1]), int (Adapter.adapt.adapter_address[2]), int (Adapter.adapt.adapter_address[3]), int (Adapter.adapt.adapter_address[4]), int (Adapter.adapt.adapter_address[5])); sMAC = acMAC; return true; } else { char acTemp[80]; ostrstream outs(acTemp, sizeof(acTemp)); outs << "error " << Ncb.ncb_retcode << " on ASTAT" << ends; sMAC = acTemp; return false; } } int main() { // Get adapter list LANA_ENUM AdapterList; NCB Ncb; memset(&Ncb, 0, sizeof(NCB)); Ncb.ncb_command = NCBENUM; Ncb.ncb_buffer = (unsigned char *)&AdapterList; Ncb.ncb_length = sizeof(AdapterList); Netbios(&Ncb); // Get all of the local ethernet addresses string sMAC; cout << "MY INFO : AdapterList.length = " << static_cast(AdapterList.length) << endl; for (int i = 0; i < AdapterList.length; ++i) { if (GetAdapterInfo(AdapterList.lana[i], sMAC)) { cout << "Adapter " << int (AdapterList.lana[i]) << "'s MAC is " << sMAC << endl; } else { cerr << "Failed to get MAC address!

Une chose: penser à la librairie netapi32.lib dans les options de ton linker. Cordialement. ADPro22.
