Winsock - Connect to Internet through specified adapter

I try to write a program using WINSOCK. I am trying to connect to the internet from a laptop with some network adapters ( LAN, WIRELESS,An USB ADSL Modem). It sounds, when I call connect function, it tries to connect using LAN, so because LAN is not connected it fails. Here are my questions: 1)How can I force a socket to use a specified Network Adapter? 2)How can I find which adapter is connected to internet? Thanks for reading and answering

Before calling connect(), use bind() on the socket and specify the local IP of the desired interface. It's fine to call bind() on a client socket -- just don't call listen().
