#  Any string automatically begins a fully-functional 30-day trial.
success = sftp.UnlockComponent("Anything for 30-day trial")

end

#  Set some timeouts, in milliseconds:
sftp.put_ConnectTimeoutMs(5000)
sftp.put_IdleTimeoutMs(10000)

#  Connect to the SSH server.
#  The standard SSH port = 22
#  The hostname may be a hostname or IP address.

#  Authenticate with the SSH server.  Chilkat SFTP supports
#  both password-based authenication as well as public-key
#  authentication.  This example uses password authenication.
success = sftp.AuthenticatePw("myLogin","myPassword")

#  After authenticating, the SFTP subsystem must be initialized:
success = sftp.InitializeSftp()
if (success != true)
    print sftp.lastErrorText() + "\n"
    exit
end

#  Open a file on the server:

handle = sftp.openFile("hamlet.xml","readOnly","openExisting")
if (handle == nil )
    print sftp.lastErrorText() + "\n"
    exit
end

#  Download the file:
success = sftp.DownloadFile(handle,"c:/temp/hamlet.xml")
if (success != true)
    print sftp.lastErrorText() + "\n"
    exit
end

#  Close the file.
success = sftp.CloseHandle(handle)
if (success != true)
    print sftp.lastErrorText() + "\n"
