    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    ftp := chilkat.NewFtp2()

    ftp.SetHostname("ftp.example.com")
    ftp.SetUsername("login")
    ftp.SetPassword("password")

    // To use a SOCKS4 or SOCKS5 proxy, simply set the following
    // properties prior to connecting:
    // The SOCKS hostname may be a domain name or 
    // IP address:
    ftp.SetSocksHostname("www.mysocksproxyserver.com")
    ftp.SetSocksPort(1080)
    ftp.SetSocksUsername("myProxyLogin")
    ftp.SetSocksPassword("myProxyPassword")
    // Set the SOCKS version to 4 or 5 based on the version
    // of the SOCKS proxy server:
    ftp.SetSocksVersion(5)
    // Note: SOCKS4 servers only support usernames without passwords.
    // SOCKS5 servers support full login/password authentication.

    // Connect and login to the FTP server.
