Socket Programming with MFC

Is there any support for Ipv6 socket programming by MFC so that we can connect to a server having Ipv6 address using Microsoft foundation classes? I have read this link but it is not much help to me.

The code here works for me:

LPCTSTR lpszHost = L"::1"; 
CSocket socket; 
int nPort = 1234;
ADDRINFOT addrInfo;
memset( &addrInfo, 0, sizeof( addrInfo ) );
addrInfo.ai_family = AF_INET6;
addrInfo.ai_socktype = SOCK_STREAM;

if ( socket.CreateEx( &addrInfo ) )
{
    struct sockaddr_in6 addr;
    memset( (LPVOID)&addr, 0, sizeof( addr ) );
    addr.sin6_family = AF_INET6;
    addr.sin6_port = htons( nPort );
    InetPtonW( AF_INET6, lpszHost, &addr.sin6_addr );
#ifdef MY_SOCKET_SERVER
// Server
    BOOL bSuccess = socket.Bind( reinterpret_cast<const sockaddr*>(&addr), sizeof(sockaddr_in6) );
#else 
// Client
    BOOL bSuccess = socket.Connect( reinterpret_cast<const sockaddr*>(&addr), sizeof(sockaddr_in6) );        
#endif
}

The CAsyncSocket does support IPv6 sort of. There are several methods to do that:

  • ConnectEx
  • BindEx
  • ReceiveFromEx
  • SendToEx
  • GetSockNameEx
  • GetPeerNameEx

However, I'd suggest using Winsock 2 API directly.
