SFTP Upload from Local Filesystem

Demonstrates how to upload a file to an SSH server. There are no limitations on file size, and the file is streamed directly from the local filesystem.

LOCAL loSftp
LOCAL lnSuccess
LOCAL lnPort
LOCAL lcHostname
LOCAL lcHandle

*  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

*  Set some timeouts, in milliseconds:
loSftp.ConnectTimeoutMs = 5000
loSftp.IdleTimeoutMs = 10000

*  Connect to the SSH server.
*  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

*  Authenticate with the SSH server.  Chilkat SFTP supports
*  both password-based authenication as well as public-key
*  authentication.  This example uses password authenication.
lnSuccess = loSftp.AuthenticatePw("myLogin","myPassword")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loSftp.LastErrorText)
    QUIT
ENDIF

*  After authenticating, the SFTP subsystem must be initialized:
lnSuccess = loSftp.InitializeSftp()
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loSftp.LastErrorText)
    QUIT
ENDIF

*  Open a file for writing on the SSH server.
*  If the file already exists, it is overwritten.
*  (Specify "createNew" instead of "openOrCreate" to
*  prevent overwriting existing files.)

lcHandle = loSftp.OpenFile("hamlet.xml","writeOnly","openOrCreate")
IF (lcHandle = NULL ) THEN
    =MESSAGEBOX(loSftp.LastErrorText)
    QUIT
ENDIF

*  Upload from the local file to the SSH server.
lnSuccess = loSftp.UploadFile(lcHandle,"c:/temp/hamlet.xml")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loSftp.LastErrorText)
    QUIT
ENDIF

*  Close the file.
lnSuccess = loSftp.CloseHandle(lcHandle)
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loSftp.LastErrorText)
    QUIT
ENDIF

=MESSAGEBOX("Success.")
