require 'chilkat'

ftp = Chilkat::CkFtp2.new()

#  Any string unlocks the component for the 1st 30-days.
success = ftp.UnlockComponent("Anything for 30-day trial")
if (success != true)
    print ftp.lastErrorText() + "\n"
    exit
end

ftp.put_Hostname("www.example-code.com")
ftp.put_Username("example-code.com")
ftp.put_Password("****")

ftp.put_ProxyHostname("ftp.myproxyhost.com")
ftp.put_ProxyPort(21)
#  Note: Your FTP Proxy server may or may not require authentication.
ftp.put_ProxyUsername("myProxyUsername")
ftp.put_ProxyPassword("myProxyPassword")

#  The ProxyMethod should be an integer value between 1 and 5.
#  If you know your FTP proxy server's authentication scheme,
#  you may set it directly.  To determine the ProxyMethod,
#  call DetermineProxyMethod.  A return value of -1 indicates a failure.
#  A return value of 0 indicates that nothing worked.
#  A return value of 1-5 indicates the ProxyMethod that was
#  successful, and this should be the value used for the ProxyMethod
#  property.

pMethod = ftp.DetermineProxyMethod()
print pMethod.to_s() + "\n";
