The problem is that Job.Tag doesn't hold the file name. It holds an object of type JobTag which is used internally.

you mean i add link1 to call the code Private link1 As String


or i add "http://moysar.com/download/molay.mp3"

Log("Job completed: " & Job.Success)
If Job.Success Then
Dim OutStream As OutputStream
Log("DownloadReady: "&link1)
OutStream = File.OpenOutput(File.DirRootExternal, link1 ,False) ' Job.Tag is read to set the Original Filename we specify earlier in the creation of the Job

File.WriteString(File.DirDefaultExternal,link1, Job.GetString)

Log(File.ReadString(File.DirDefaultExternal, link1))

File.Copy2(Job.GetInputStream,OutStream ) ' save the file
OutStream.Close
Else
Log("Error: " & Job.ErrorMessage)
ToastMessageShow("Error: " & Job.ErrorMessage, True)
End If
Job.Release

Without posting the error you say you get it is hard to imagine what you are doing.....

LEARN TO WRITE GOOD HELP-REQUESTS!

- Post the code you are using (not part of them. better the project exported as zip)
- and the EXACT error you got (NOT A JPG, the error from log as text).
- describe when exactly you get this error and what you have tried so far (the code you tried)

With the infos you provided i just can use a wonderglas or even guess something which could be the problem! I don´t want to help with so much less informations provided!

.
.

For the others who read this here; i got an personal mail from @ibra939 to help with this problem and he gave me just the link to page 7 of this thread. That´s all... So i read the last post and read a "i´ll try it"... lol

With 2 event names and 2 progress subs!

B4X:
Sub Button1_Click
Dim download1 As DownloadData
download1.url = "http://file1.com"
download1.EventName = "download1"
download1.Target = Me
end sub

Sub Button2_Click
Dim download2 As DownloadData
download2.url = "http://file1.com"
download2.EventName = "download2"
download2.Target = Me
end sub

Sub download1_Progress(Progress As Long, Total As Long)
ProgressBar1.Progress = Progress / Total * 100
Label1.Text = NumberFormat(Progress / 1024, 0, 0) & "KB / " & _
NumberFormat(Total / 1024, 0, 0) & "KB"
End Sub

Sub download2_Progress(Progress As Long, Total As Long)
ProgressBar1.Progress = Progress / Total * 100
Label1.Text = NumberFormat(Progress / 1024, 0, 0) & "KB / " & _
NumberFormat(Total / 1024, 0, 0) & "KB"
End Sub

End Sub
Thanks you for this suggestion, but How can I do if I want to download a lot of files without knowing about the number of downloads (I can say the number of progress subs) in advance?

Do you want to download all of these files at once?

You can create a class instance for each download that will handle the event (set it with the Target parameter). However you are probably making it more complicated than it should be.

You can decide to download up to 3 files at once and then start the next download each time the previous one completes. The overall download time will most probably be the same.

Thank @Erel Yes, I want to download all of these files at once with their own progress bar! How to do that?

Create a class that holds a ProgressBar and use it to handle the events. Now you can create an instance of this class for each download.

For this method, do we still need to write many progress subs by hand? For example,
sub download2_Progress, sub
download3_Progress,...?
