libURLDownloadToFile progress download

[link76]

Hi,

I'm follow one of the lessons here:- http://lessons.livecode.com/s/lessons/m ... a-download

I would like to replace

Code: Select all

load URL tDownloadLink with message "downloadComplete"

with "libURLDownloadToFile" because I can not download the file properly.

I tried this way but download works only in development environment

Code: Select all

libURLDownloadToFile, tDownloadLink, ("binfile:" & IT),"downloadComplete"

thank you

Hi,

I used to use libURLDownloadToFile but stopped for some reason. These always work for me (I have an FTP server)

Code: Select all

put url ftpfilename into url ("binfile:" & localfilename)

Code: Select all

put urlencode(ftpfilename) into url ("binfile:" & localfilename)

I suspect that removing the binfile from your code might make it work, since libURLDownloadToFile does binary automatically.

For detecting errors,

Code: Select all

put the result into tError

and do whatever you want with tError. If it's empty, no errors were detected. The script doesn't progress until the file has been downloaded, anyway.

I tried this way:

Code: Select all

libURLDownloadToFile, tDownloadLink,  IT, "downloadComplete"

but work only development environment

Hi,

but work only development environment

Did you insert Internet inclusion in your standalone ?

And there is NO comma after the command name "liburldownload", and better NOT use IT here, put it into a variable first to avoid surprises:

Code: Select all

...
put it into tFileNameOnDisk
...
libURLDownloadToFile tDownloadLink, ("binfile:" & tFileNameOnDisk),"downloadComplete"
...

Hi,

the setting of save standalone application is set to: search for required inclusions ....

[Klaus]

Oh, and only provide the filename here:

Code: Select all

...
put it into tFileNameOnDisk
...
## libURLDownloadToFile tDownloadLink, ("binfile:" & tFileNameOnDisk),"downloadComplete"
libURLDownloadToFile tDownloadLink, tFileNameOnDisk,"downloadComplete"
...

I found that the automatism "Search for required inclusions..." does not always work sufficiently, so better set up your inclusions manually!

[link76]

this code how should it be modified?

Code: Select all

put "http://my_url/setup.exe" into tDownloadLink  -- 2MB
         
           
            libURLSetStatusCallback "showProgress", the long name of me
            	
            -- make sure the progress bar is hidden, as this property is used to initialise it
            hide scrollbar "ProgressBar"
            hide group "group Login"
            show group "group update"
            put empty into fld "ProgressField"
            put the seconds into sDownloadStart
           
           load URL tDownloadLink with message "downloadComplete" (don't work!!!)

 .....

I set up inclusions manually but not work, which files should appear in extensions?

Hi,

Code: Select all

 load URL tDownloadLink with message "checkStatus" (don't work!!!)

I think you might use something like that:

Code: Select all

local tDownloadLink

...
         libUrlSetStatusCallback "checkStatus",the long id of me
         libURLDownloadToFile tDownloadLink,DestinationFolder
...
on checkStatus pURL,pStatus
   if pURL = tDownloadLink then
      
      --•• watch process
      --       if the vis of group "grDevTools" then
      --          put the ticks & "," & "checkStatus"   & "," & pUrl & "," & pStatus & cr before fld "fSpy"
      --       end if
      --•••
      
      switch (item 1 of pStatus)
         case "loading"
           -- setpb item 3 of pStatus,word 1 of item 2 of pStatus -- custom progressbar
            break
         case "downloaded"
        --    set the rect of grc "bar" to the rect of grc "border" -- custom progressbar
       --     send "AfterDownload" to me in 1 seconds
            break
         default -- contacted, requested, etc.
      end switch 
   end if
end checkStatus

Hi jmburdon,

I tried your code, it works in development environment but when I create the standalone application, a file is downloaded to 0 bytes

Code: Select all

local tDownloadLink

on mouseUp
   
   put "http://myurl.it/setup.exe" into tDownloadLink
   
   set the itemDel to slash
   put last item of tDownloadLink into tFilename
   put specialFolderPath("Desktop") & slash before tFileName
   put URL tFileName into URL ("binfile:" & tFileName)
   
   put tFileName into DestinationFolder

   
   libUrlSetStatusCallback "checkStatus",the long id of me
   libURLDownloadToFile tDownloadLink,DestinationFolder
   
end mouseUp

on checkStatus pURL,pStatus
   
   if pURL = tDownloadLink then
      

      switch (item 1 of pStatus)
         case "loading"
            -- setpb item 3 of pStatus,word 1 of item 2 of pStatus -- custom progressbar
            break
         case "downloaded"
        --    set the rect of grc "bar" to the rect of grc "border" -- custom progressbar
            --     send "AfterDownload" to me in 1 seconds
            break
         default -- contacted, requested, etc.
      end switch 
   end if
end checkStatus

Hi,
What about this :

Code: Select all

local tDownloadLink

on mouseUp
   put "http://myurl.it/setup.exe" into tDownloadLink
   set the itemDel to slash
   put last item of tDownloadLink into tFilename
   set the itemDel to ","
   put specialFolderPath("Desktop") & slash before tFileName
   --    put URL tFileName into URL ("binfile:" & tFileName)
   --    put tFileName into DestinationFolder
   libUrlSetStatusCallback "checkStatus",the long id of me
   libURLDownloadToFile tDownloadLink,tFilename
end mouseUp

Hi all,

I finally solved the problem.

The problem is in the revsecurity.dll library that is not implemented in the standalone application, copying it manually works!

I don't see revsecurity.dll in inclusions list. Where did you find it ?

Hi Jean-Marc,

I use LC 5.5, I have a commercial license.
When I created the standalone application, specifying the url: http: // myurl, it included the library in the root folder.

Thanks,
That could be useful for some unusual users of windows (i'm one of them)
