*** IMPORTANT:
*** For Progress information and Cancellation
*** we have to pass this instance to the .NET client
loFtp.oSFtp.wwSftp = loFtp

*** Set up the Event Binding - map to BufferUpdate() method below
BINDEVENT(loFtp,"OnFtpBufferUpdate",this,"OnBufferUpdate")

lcOutputFile = ".\tests\sailbig_downloaded.jpg"
DELETE FILE lcOutputFile

loFtp.FtpConnect()

lnResult = loFtp.FtpGetFileEx("sailbig.jpg",lcOutputFile)

loFtp.FtpClose()

this.AssertTrue(loFtp.lCancelDownload == .F.,"This download has been cancelled")
this.AssertTrue(lnResult == 0,loFtp.cErrorMsg)
this.AssertTrue(FILE(lcOutputFile))

ENDFUNC

*** This is the Event Handler Implementation
FUNCTION OnBufferUpdate(lnbytesdownloaded,lnbufferreads,lccurrentchunk, lnTotalBytes, loFtp)

WAIT WINDOW NOWAIT TRANSFORM(lnBytesDownloaded) + " of " + TRANSFORM(lnTotalBytes)

*** Optionally cancel the download
IF (lnBytesDownloaded > 26000)
    *** This is the loFTP instance from above
