Dim ftp As New Chilkat.Ftp2

ftp.Hostname = "www.example-code.com"
ftp.Username = "example-code.com"
ftp.Password = "****"

ftp.ProxyHostname = "ftp.myproxyhost.com"
ftp.ProxyPort = 21
' Note: Your FTP Proxy server may or may not require authentication.
ftp.ProxyUsername = "myProxyUsername"
ftp.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.

Dim pMethod As Integer = ftp.DetermineProxyMethod()
Debug.WriteLine(pMethod)

Dim success As Boolean = ftp.Disconnect()
