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

loFtp = CreateObject('Chilkat.Ftp2')

loFtp.Hostname = "ftp.example.com"
loFtp.Username = "login"

* Connect and login to the FTP server.
lnSuccess = loFtp.Connect()
IF (lnSuccess <> 1) THEN
    ? loFtp.LastErrorText
    RELEASE loFtp
    CANCEL
ENDIF

* Change to the remote directory where the file is located.
* This step is only necessary if the file is not in the root directory
* for the FTP account.
lnSuccess = loFtp.ChangeRemoteDir("temp")

* To resume a download, it is assumed that the partial file
* is already present on the local filesystem.
* You only need to set the RestartNext property to resume
* the download.  The Chilkat FTP component sets the resume
* point by getting the existing size of the target (local) file.
