Help: getting updates from a remote server.

I'm having my first steps with FiveWin / xHarbour.
My customers need to download updated data from our servers to keep their database up to date. Is there is a way that they can download their data (if entitled to, subscription based) automatically ? Something like anti-virus software does it ? How can this be done using FiveWin ?

you can use tftp class to get files.

In addition to tftp you can even use tWebClient and the IE-ActiveX to retrieve remotely hosted files.

Code: Select all
// Create ftp connect
oFtp := TFtp():New( cFTP_IP, oInternet, cUsername, cPassword )
If oFtp:hFtp == 0
Tone( 1000, 1 )
MsgStop( "Ftp connect fail!", "Error!" )
oFtp:End()
Exit
EndIf
:

:
// Open remote file
oFtpFile := TFtpFile():New( cServerFile, oFtp )
oFtpFile:lBinary := .T.
//
oFtpFile:OpenRead() // Open and Read mode
If oFtpFile:nError <> 0
Tone( 1000, 1 )
MsgStop( "ftp file:["+cServerFile+"]Open & read fail!!", "Error!" )
oFtpFile:End()
lRet := .F.
Exit
EndIf

TWebClient allows you retrieving a file via the standard http port 80. Please see \fwh\samples\webclien.prg
For the IE-ActiveX you need the most recent FWH. Antonio has posted a sample at:

hi,
If webclient / TFTP can overwrite even if the file is open or at running ?
For example: my.exe ,my.dll,libmysql.dll are running, overwrite them besides they are running.
Under Linux ,could.
