LOCAL lnSuccess

*  Important: It is helpful to send the contents of the
*  sftp.LastErrorText property when requesting support.

loSftp = CreateObject('Chilkat.SFtp')

*  Any string automatically begins a fully-functional 30-day trial.

lnSuccess = loSftp.UnlockComponent("Anything for 30-day trial")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loSftp.LastErrorText)
    QUIT
ENDIF

*  To connect through an HTTP proxy, set the HttpProxyHostname
*  and HttpProxyPort properties to the hostname (or IP address)
*  and port of the HTTP proxy.  Typical port numbers used by
*  HTTP proxy servers are 3128 and 8080.
loSftp.HttpProxyHostname = "www.my-http-proxy.com"
loSftp.HttpProxyPort = 3128

*  Important:  Your HTTP proxy server must allow non-HTTP
*  traffic to pass.  Otherwise this does not work.

*  Connect to the SSH server through the HTTP proxy.
*  The standard SSH port = 22
*  The hostname may be a hostname or IP address.

lcHostname = "www.my-ssh-server.com"
lnPort = 22
lnSuccess = loSftp.Connect(lcHostname,lnPort)
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loSftp.LastErrorText)
    QUIT
ENDIF

*  Your application is now connected to an SFTP/SSH server
*  through an HTTP proxy.
