[ukoenig]

Thank You very much for all the help.

I will carry on with testing.

with testing the FWH sample from < samples/GalleryIcopyfil/Icopyfil.prg >
I reached this point : serverconnection, but the copyprocess doesn't start.

I listed the homepage-directory :

aFiles = oFTP:Directory( "*.*" ) // , "D" )
AEval( aFiles, { | aFile | MsgInfo( aFile[ 1 ], aFile[ 3 ] ) } )

results :
------------------
.
..
Firma
Testfile.zip // a testfile
Service // subdirectory
Software // Subdirectory
_we_info // file
index.html // file
-------------------

my downloadfiles are inside the subdirectory < Software/DOWNLOADS >
that can be the reason that no download is executed



regards
Uwe

[Silvio.Falconi]

sorry Uwe I saw now your message

the tupdate class here run ok perhaps there is a protection on your website ?
do you have CLASS TFTP ?

[ukoenig]

Silvio,

NO nothing special or protection
From inside the Forum there is no problem to download a file.
There is nothing else I need.
With the FWH-sample ( defined above ) I can open the homepage and check the directory.
Maybe I have to check the solution from Stephan again

regards
Uwe

[ukoenig]

Silvio,

the solution from Stephan
after some more tests, I found the problem and got it working

there is a directory problem

my files are stored inside a subdirectory of < Software >
< Software > is one of the subdirectorys of < root >
inside < Software > a subdirectory < DOWNLOADS > is defined for downloads
it only workes storing files in subdirectory < Software > ( 1. level )

LOCAL cFtpDir := "Software" // a subdirectory of ROOT -> works !!!
using
LOCAL cFtpDir := "Software/DOWNLOADS"
doesn' work

-------------------------
. // Root
..
Software // Subdirectory
Software/DOWNLOADS // Subdirectory of download-files
--------------------------

that means I have to save all downloadfiles in < Software > or create a new directory.

I think with :
::oFtp:SetCurrentDirectory( ??????? )
it is possible to move to any subdirectory ?

regards
Uwe

    function Main()
            LOCAL   nRet
           
            nRet := DOWNLOADFILE( "http://www.yoursite.it/index.html", "C:\index.html" )
           
            MsgStop( nRet )
    RETURN NIL


    #pragma BEGINDUMP

    #include <WinTen.h>

Dear Antonio,

URLDownloadToFile

Is this only for Harbour.
