    // To use a SOCKS4 or SOCKS5 proxy, simply set the following
    // properties prior to calling Connect.  The connection may be SSL/TLS or 
    // non-secure - both will work with a SOCKS proxy.
    // The SOCKS hostname may be a domain name or 
    // IP address:

    // Set the SOCKS version to 4 or 5 based on the version
    // of the SOCKS proxy server:
    CkSocketW_putSocksVersion(socket,5);
    // Note: SOCKS4 servers only support usernames without passwords.
    // SOCKS5 servers support full login/password authentication.

    // Connect to port 5555 of 192.168.1.108.
