Re: UDP Broadcast message when system has more than one network card

I have an application that broadcast a UDP pack to all devices for reply.
When a system has more than one network card it seems to only broadcast it
only on the first card that was installed in the machine. How do I get it
to
broadcast on all network devices on my system?

I am using,

Create(0, SOCK_DGRAM);
BOOL bMultipleApps = TRUE;
SetSockOpt(SO_REUSEADDR, (void*)&bMultipleApps, sizeof(BOOL), SOL_SOCKET);
SetSockOpt(SO_BROADCAST, (void*)&bMultipleApps, sizeof(BOOL), SOL_SOCKET);

SendTo(pBuffer, nSize, nPort, NULL, MSG_DONTROUTE);
