Function to download a defined file from a homepage ?

[ukoenig]

Hello,

1. is there a function to download a defined file from my homepage ?
I need a solution, the user can download a given zip-file for a update on buttonaction.

sample :
cUrl := "http://www.pflegeplus.com/DOWNLOADS/Myupdate.zip"
the same like we do in the forum for download :
[url]????????[/url]

2. a solution to place a DBF in the CLOUD to be used to update the file on another computer ?

best regards
Uwe

[Silvio.Falconi]

there a clas called s TUpdate from our friend Prof. Ing. Stephan Haupt ( great loss we hope he rest in peace forever)

[ukoenig]

Silvio,

thank You for the info.
I didn't know about it.
It seems to be the solution I'm looking for.

regards
Uwe

      Class TUpdate - application update over ftp
       --------------------------------------------------
       (based on a function from Biel Maimo)

       Version 1.3
       (c) Stefan Haupt 2012 / 2013

       Description: This is a claas to update your application over a Ftp-Server.
                    Itïs very easy to use, I think the code is self explaining. You
                    just need some vars to be set, the update is automatically done.
                    That means your application is closed, the files are copied and
                    your application is restarted.
       Sample:
               FUNCTION Update ()

                 LOCAL oUpdate
                 LOCAL cFtp  := "YourFtpServer"
                 LOCAL cUser := "YourLoginName"
                 LOCAL cPW   := "YourPassword"
                 LOCAL cFtpDir   := "YourUpdateFolderOnFtp"
                 LOCAL cUpdFile  := "NameOfTheUpdatefile"
                 LOCAL cLocalDir := "NameOfTheLocalDir"
                 LOCAL nFlags := <SpecialConnectionFlags> // flag to set passive mode

                 oUpdate := TUpdate():New(cFtp, cUser, cPW, cFtpDir, cUpdFile, cLocalDir+"Updates\")
                 oUpdate:nFlags := nFlags
                 oUpdate:Update ()
                 oUpdate:End ()

               RETURN (nil)
       ****************************************************************************
       Remarks: If you want to use the passive mode in your ftp connection, you have
       to update the class TFtp that comes with fwh.
       Just replace the method new with this one:

           METHOD New( cFTPSite, oInternet, cUserName, cPassword, nFlags ) CLASS TFTP

             DEFAULT nFlags := 0

             ::oInternet = oInternet
             ::cSite     = cFTPSite
             ::cUserName = cUserName
             ::cPassword = cPassword

             if oInternet:hSession != nil
                ::hFTP = InternetConnect( oInternet:hSession, cFTPSite, FTP_PORT,;
                                          ::cUserName, ::cPassword,;
                                          INTERNET_SERVICE_FTP, nFlags, 0 )
                AAdd( oInternet:aFTPs, Self )
             endif

          return Self

Silvio,

NO connection to the server

my function

// cPW := "anonymous@localhost",;
// cFtpFolder := "/",;
// cZipFile := "",;
// cLocalDir := cFilePath( GetModuleFileName( GetInstance() ) ) + "Updates\" ,;
// nFlags := 0

FUNCTION PFL_DOWNLD()
LOCAL oUpdate
LOCAL cFtp := "www.pflegeplus.com"
//LOCAL cFtp := "http://www.pflegeplus.com" // test

LOCAL cFtpDir := "/Software/DOWNLOADS/" // downloaddir
LOCAL cUpdFile := "BARTEST1.zip" // file
LOCAL cLocalDir := "I:/DOWNLOADS/" // destination

oUpdate := TUpdate():New( cFtp, cUser, cPW, cFtpDir, cUpdFile, cLocalDir +"Updates\" )
oUpdate:nFlags := nFlags
oUpdate:Update()
oUpdate:End ()

RETURN ( NIL )

I got the message < Server not found, no connecction possible >

A normal working download looks like : http://www.pflegeplus.com/DOWNLOAD/Test.zip

my normal working connection

I don't think it works for http://www.mysite.com it has to be ftp.mysite.com
It works with FTP port.
I have it working for a couple of my programs.

[byte-one]

Uwe, no answer to connection, but

Code: Select all  Expand view

LOCAL cLocalDir := "I:/DOWNLOADS/" // destination

should be

Code: Select all  Expand view

LOCAL cLocalDir := "I:\DOWNLOADS\" // destination

[ukoenig]

I tested everything, but NO connection

a minimumtest only to connect :

FUNCTION DOWNLD()
LOCAL oUpdate
LOCAL cFtp := "www.pflegeplus.com"
LOCAL cUser := "---------" // user
LOCAL cPW := "---------" // password

oUpdate := TUpdate():New( cFtp, cUser, cPW )
oUpdate:Update()
oUpdate:End ()

RETURN ( NIL )

my working settings to connect without any problems :



there is a short running-message of the connection-try



any idea ?

tested as well

LOCAL cFtp := "ftp.pflegeplus.com"

NO connection.

Do you have a FTP setup on your server using port 21?
The TUpdate I use works only if there is a FTP server. If you are trying to download file from regular Web server then it will not work.

Code: Select all  Expand view

//TUpdate uses tFTp class
::oFtp      := tFtp():New(::cIp, ::oInternet, ::cUser, ::cPW, ::nFlags) }
 

[ukoenig]

Gale,

I'm afraid that it is the problem.

FOUND !!!

nothing else I need

ACTION DOWNLD( oDlg1,"Trtext1zip")
-----------------
FUNCTION DOWNLD( oDlg1, cFile )
cDownload := "http://www.pflegeplus.com/DOWNLOADS/" + cFile
ShellExecute( oDlg1, ,cDownload, , , 5 )
RETURN ( NIL )

the download-result of a defined zip-file



It would be perfect, to copy the download straight to the defined folder.
I think it can be fixed defined what to do with the zip-file.

Still much better maybe possible a < QUITE > download

because there are many tools stored in the homepage as a download
You can collect the download-links and simply download them with just one line like :
ShellExecute( oDlg1, ,"http://www.pflegeplus.com/DOWNLOADS/Trtext1zip", , , 5 ) // download of alphabmp-sample

maybe Your defined vars are different ?

Massimo,

got a error

unresolved external < URLDownloadToFileA >

not possible to compile.

I tested from samples : Icopyfil.prg and could connect to my homepage
but maybe still something wrong because there is no visible downlod process

FTPGetFiles( "www.pflegeplus.com", ;
{ "Software\DOWNLOADS\cPicker1.zip" }, ;
{ "I:\cPicker1.zip" } )

MsgRun( "Verbinde mit Internet...", "Bitte warten",;
{ || oInternet := TInternet():New(),;
oFTP := TFTP():New( cFTPSite, oInternet, "-------", "--------" ) } ) // name and password needed !!!
