I suggest that for just the MAC address the command getmac i sprobably more suited to your needs as it is more terse but it does not include IP address.
Programmatically I have used GetAdaptersInfo. You need to include the files
#include <iprtrmib.h>
#include <Iphlpapi.h>
from the microsoft paltform sdk.
The sort of code you need is as follows
##start of code sample
DWORD dwNumInterfaces;
GetNumberOfInterfaces(&dwNumInterfaces);
//IP_ADAPTER_INFO AdapterInfo[16]; // Allocate information
IP_ADAPTER_INFO* AdapterInfo = new IP_ADAPTER_INFO[dwNumInterfaces];
DWORD dwBufLen = sizeof(*AdapterInfo); // Save memory size of buffer
DWORD dwStatus = GetAdaptersInfo(
AdapterInfo, // [out]
&dwBufLen); // [in]
assert(dwStatus == ERROR_SUCCESS); // Verify return value is
// valid, no buffer overflow
PIP_ADAPTER_INFO pAdapterInfo = AdapterInfo;
FormatMACaddress(pAdapterInfo->Address,rstrMacAddress);
current adapter info
do {
DoSomethingFunction(pAdapterInfo->Address); // process MAC address
pAdapterInfo = pAdapterInfo->Next; // Progress through
// linked list
}
while(pAdapterInfo); // Terminate if last adapter
delete [] AdapterInfo;
##end of code sample
: This problem was mostly solved.
:
: I'll explain the solution for those who may face similar problems later.
:
: 1.
: I used redirection on the ipconfig command to store output in a textfile.
:
: ipconfg/all > output.txt
:
: 2. One of my programs opens this file(output.txt) and searches the output for "Physical address" and "IP address" and tries to identify the one for the video card. There are many other lines for physical address so the program is somewhat guessing on the right one. I used the "Description" and title lines for each component to determine which was most likely for the Network Interface Card(NIC).
:
: 3. Output the extracted MAC address and IP address.
:
:
: I'm still facing problems with making a flexible detection scheme that will detect the correct section of output for the NIC card as apposed to the router and other devices.

: : Hello,
: :
: : How can you get the MAC address programmatically from the computer the code runs on?
: :
: : This should be a little easier. How do you get the IP address from the current computer? My methods are a little clumsy, for example parsing the output from ipconfig.

: : I'm using Windows XP on a Novell network, if this helps.
