You may use GETNETCARDID()

I am using xHarbour with FWH.

NageswaraRao,

Are you using xHarbour commercial ?

Add IPHLPAPI.LIB from bcc55 into your script if your are using bcc

I am using xharbour with bcc55. not the commercial version. i included the lib iphlpapi.lib as advised by srrao and now its working fine. thanks mr. antonio and mr. sanjay

NageswaraRao,

Yes, right, that library is needed. We already provided it included in samples\buildh.bat. I guess you are using an older version of buildh.bat.

Hi,

I'm getting a unresolved external __chkstk when I try to use this

Alex,

Try linking Borland cw32.lib

A borland library with commercial xharbour?

ops, my mistake

Then you should require it to xHB guys.

If I am not wrong, __chkstk stands for check stack, so you could safely create a dummy C function with such name

void _chkstk( void ) { }

If I add that dummy function, GetNetCardID kills my app.

Will ask on xhb newsgroup

Alex,

> Will ask on xhb newsgroup

Yes, its the right way

Posted: **Thu Jun 07, 2007 8:32 am**

Alex,

Just out of curiosity, please try it this way:

BOOL _chkstk( void ) { return TRUE; }

No luck

Busy trying to get following code to work. It compiles. I just need to figure out how to return an array of adapter names and addresses

Code: Select all

#include <iphlpapi.h>

// Fetches the MAC address and prints it
static void GetMACaddress(void)
{
  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 {
//    PrintMACaddress(pAdapterInfo->Address); // Print MAC address

    pAdapterInfo = pAdapterInfo->Next;    // Progress through
                                          // linked list
  }
  while(pAdapterInfo);                    // Terminate if last adapter
}
