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

ftp = Chilkat::CkFtp2.new()

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";

success = ftp.Disconnect()
