Yes, if we know the exact address of the file/directory.

Then you can get the file using a download manager like flashget or if you use firefox there are large number of extensions for downloading by giving the url.

But....
I wanne build something like autoupdate - my program will test if there is new version on internet and - if newer exists - downloads it and run installation.

So, I need to download new setup file directly from my application - I've tested hyperlink - it works, but in this case user action is required...

I'm use wget for windows for update my program's with execute command on minimized window.

1.- with my update program execute the wget on minimized window and i get a file in txt
2.- I read the file txt and check the version on internet
3.- If the version is new then with wget download the new version on temp folder
4.- when the file is downloaded then close the main program and replace the new program.
5.- Listo ..... :mrgreen:

P.D. My english is bad, i need more practice. jejejeje

Thanks for your suggestion. I'll try to implement it tomorrow.

I want to renew this topic.
I think installing wget is not the best way...
It works, but - on each computer running my application I need to install wget - it's hard to realize.

Maybe another idea?

I watched for samples linked with MINIGUI Extended - FTPClient - but I don't know how to use it ("ftpclient" doesn't want to compile with Minigui Ext.)

Success!!!
Two days of searching ant testing and I've compiled from everything I found, small function that is really BIG! I wanna share it with us, maybe it will be useful!
I wanna put working example with this function.

Code: Select all

PROCEDURE DownloadFromWWW
	param cURL, cLocalFileName
	LOCAL oCon, oUrl, i

	cLocalFileName := alltrim(cLocalFileName)
	
   oUrl := tURL():New( cUrl )
   IF Empty( oUrl )
      MsgBox("Invalid url " + cUrl)
      return
   ENDIF

   IF oUrl:cProto != "http"
      MsgBox('This is a header test for http. Use an http address.')
      return
   END
   
   oCon := TipClientHttp():New( oUrl )
   oCon:nConnTimeout := 20000
   MsgBox("Connecting with "+ oUrl:cServer)
   IF oCon:Open( cUrl )

	MsgBox("Connection eshtablished." +chr(10)+"Press OK to retrieve" + oUrl:cPath +oUrl:cFile)
	oCon:WriteAll(cLocalFileName)
	MsgBox("Downloaded...")
    oCon:Close()
   ELSE
      MsgBox("Can't connect with "+ oUrl:cServer)
      IF oCon:SocketCon == NIL
         MsgBox("Connection not initiated")
      ELSEIF hb_InetErrorCode( oCon:SocketCon ) == 0
         MsgBox("Server sayed: "+ oCon:cReply)
      ELSE
         MsgBox("Error in connection: " + hb_InetErrorDesc( oCon:SocketCon ))
      ENDIF
   END
RETURN
