Automatically Determine FTP Proxy Method

See more FTP Examples

Tries each of the five possible ProxyMethod settings and returns the value (1-5) of the ProxyMethod that succeeded. Xbase++

LOCAL nSuccess
LOCAL oFtp
LOCAL nPMethod

nSuccess := 0

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

oFtp := CreateObject("Chilkat.Ftp2")

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

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

nPMethod := oFtp:DetermineProxyMethod()
