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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.SFtp')
loSftp = CreateObject('Chilkat.SFtp')

* Set some timeouts, in milliseconds:
loSftp.ConnectTimeoutMs = 5000
loSftp.IdleTimeoutMs = 15000

* Connect to the SSH server.  
* The standard SSH port = 22
* The hostname may be a hostname or IP address.
lcHostname = "sftp.example.com"
lnPort = 22
lnSuccess = loSftp.Connect(lcHostname,lnPort)
IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
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
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

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

* Open a file for reading.

lcHandle = loSftp.OpenFile("myTest.txt","readOnly","openExisting")
IF (loSftp.LastMethodSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Assume the file we are reading contains the following text:
* abcdefghijklmnopqrstuvwxyz1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ
* (in ANSI format -- i.e. one byte per char).

* Read 26 bytes:

lcSText = loSftp.ReadFileText(lcHandle,26,"ansi")
IF (loSftp.LastMethodSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Should print "abcdefghijklmnopqrstuvwxyz"
? lcSText

* Read the next 10 bytes.
lcSText = loSftp.ReadFileText(lcHandle,10,"ansi")
IF (loSftp.LastMethodSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Should print "1234567890"
? lcSText

* Read the next 26 bytes.
lcSText = loSftp.ReadFileText(lcHandle,26,"ansi")
IF (loSftp.LastMethodSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Should print "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
? lcSText

* Close the file.
lnSuccess = loSftp.CloseHandle(lcHandle)
IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

? "Success."
