(Visual FoxPro) SCP Upload Contents of String to Remote File

Demonstrates how to upload the contents of a string variable using the SCP protocol (Secure Copy Protocol over SSH). The text is uploaded to a file in specific remote directory. If the file did not already exist, it is created. If it already existed, it is overwritten.

* This example requires 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.Ssh')
loSsh = CreateObject('Chilkat.Ssh')

* Connect to an SSH server:

* Hostname may be an IP address or hostname:
lcHostname = "www.some-ssh-server.com"
lnPort = 22

lnSuccess = loSsh.Connect(lcHostname,lnPort)
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* Wait a max of 5 seconds when reading responses..
loSsh.IdleTimeoutMs = 5000

* Authenticate using login/password:
lnSuccess = loSsh.AuthenticatePw("myLogin","myPassword")
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* Once the SSH object is connected and authenticated, we use it
* as the underlying transport in our SCP object.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Scp')
loScp = CreateObject('Chilkat.Scp')

lnSuccess = loScp.UseSsh(loSsh)
IF (lnSuccess <> 1) THEN
    ? loScp.LastErrorText
    RELEASE loSsh
    RELEASE loScp
    CANCEL
ENDIF

lcContent = "This string will be the contents of the remote file."
lcRemotePath = "uploads/text/testUtf8.txt"

* The utf-8 byte representation of the string will be uploaded.
* See https://www.chilkatsoft.com/p/p_463.asp for a list of valid charsets.
lcCharset = "utf-8"

* This uploads to the "uploads/text" directory relative to the HOME
* directory of the SSH user account.  
* Note: The remote target directory must already exist on the SSH server.
lnSuccess = loScp.UploadString(lcRemotePath,lcContent,lcCharset)
IF (lnSuccess <> 1) THEN
    ? loScp.LastErrorText
    RELEASE loSsh
    RELEASE loScp
    CANCEL
ENDIF

lcRemotePath = "uploads/text/testUtf8_withBOM.txt"

* To include the utf-8 preamble (also known as the BOM),
* prefix the charset name with "bom:".  Any charset that can 
* optionally include a BOM can be specified in this way.
lcCharset = "bom:utf-8"

* Uploads to a remote file that contains text in the 
* utf-8 representation, including the BOM at the start of the file.
lnSuccess = loScp.UploadString(lcRemotePath,lcContent,lcCharset)
IF (lnSuccess <> 1) THEN
