Demonstrates how to download a binary file, such as a .zip, from a Co:Z SFTP server on a z/OS IBM Mainframe. Visual FoxPro

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

loSftp = CreateObject('Chilkat.SFtp')

* Connect to the SSH server.  
lcHostname = "sftp.example.com"
lnPort = 22
lnSuccess = loSftp.Connect(lcHostname,lnPort)
IF (lnSuccess = 0) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

lnSuccess = loSftp.AuthenticatePw("myLogin","myPassword")
IF (lnSuccess = 0) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

lnSuccess = loSftp.InitializeSftp()
IF (lnSuccess = 0) THEN

    RELEASE loSftp
    CANCEL
ENDIF

* To download a binary file from the Co:Z SFTP server, 
* we must switch to binary mode in the following unconventional way.
* We pretend to fetch a directory listing for "/+mode=binary"
* This has the effect of putting the server in binary mode for transfers.
lcHandle = loSftp.OpenDir("/+mode=binary")
IF (loSftp.LastMethodSuccess = 0) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Download the "directory listing" (but it's not actually a directory listing, and we'll just discard it.)

loDirListing = CreateObject('Chilkat.SFtpDir')
lnSuccess = loSftp.ReadDirListing(lcHandle,loDirListing)
IF (lnSuccess = 0) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    RELEASE loDirListing
    CANCEL
ENDIF

* Close the directory handle:
lnSuccess = loSftp.CloseHandle(lcHandle)
IF (lnSuccess = 0) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    RELEASE loDirListing
    CANCEL
ENDIF

* Download the binary file:
lcLocalFilePath = "c:/temp/test.zip"
lcRemoteFilePath = "test.zip"
lnSuccess = loSftp.DownloadFileByName(lcRemoteFilePath,lcLocalFilePath)
IF (lnSuccess = 0) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    RELEASE loDirListing
    CANCEL
ENDIF

? "Success."

RELEASE loSftp
