Italian Dropbox. Da una cartella download OK e da un'altra no...

[Sabotto]

Finalmente sono riuscito ad accedere al mio Dropbox.
Ora vorrei scaricare un file dalla mia cartella di DropBox alla cartella dell'app e scrivo:

Dir NomeFile as string = "pippo.txt"
Dim DirDropBox as String = "\Dropbox Lavoro\Turni Telec"
Dim DirDestination As String = RP.GetSafeDirDefaultExternal("TurniTel")

'copio il file dalla cartella di DropBox alla cartella Files/Turni della mia app
dbxFiles.download(File.Combine(DirDropBox,NomeFile), DirDestination, NomeFile) ' non funziona

Non lo copia (o meglio mi crea "pippo.txt" vuoto)
Ho provato allora a creare un'altra cartella sotto DropBox Lavoro "\DropBox Lavoro\Turni Telec 2" con all'interno lo stesso file "pippo.txt"
Ripeto il comando e stavolta lo copia

Dir NomeFile as string = "pippo.txt"
Dim DirDropBox as String = "\Dropbox Lavoro\Turni Telec 2"
Dim DirDestination As String = RP.GetSafeDirDefaultExternal("TurniTel")

'copio il file dalla cartella di DropBox alla cartella Files/Turni della mia app
dbxFiles.download(File.Combine(DirDropBox,NomeFile), DirDestination, NomeFile) ' funziona!!!

Cosa devo controllare nella cartella "Turni Telec" e in quella "Turni Telec 2" per capire dove sta la differenza fra le due?
Ho poi provato con un file PDF messo nella cartella "Turni Telec 2" e neanche lui viene copiato (viene generato un file di taglia 0)
Quindi non dipende dalla cartella
Da cosa puo dipendere?
Non capisco perchè a volte lo copia e a volte no

Prova così

Dir NomeFile as string = "pippo.txt"
Dim DirDropBox as String = "\Dropbox Lavoro\Turni Telec"
Dim DirDestination As String = RP.GetSafeDirDefaultExternal("TurniTel")

'copio il file dalla cartella di DropBox alla cartella Files/Turni della mia app
dbxFiles.download(File.Combine(DirDropBox,NomeFile), DirDestination, NomeFile) ' non funziona
Wait for (dbxfiles) jobdone(dbxfiles as httpjob)
If dbxfiles.success then
   'File scaricato OK
Else
   'Qualcosa è andato storto
End if

In pratica attendi che il download sia effettivamente finito prima di proseguire.

I do not speak your language so i´ll answering in english here:

Wait for (dbxfiles) jobdone(dbxfiles as httpjob)

Dropbox JAVA Library is not using httpjobs.

For a possible solution see:

Dropbox SDK V2 - Java: problem downloading

Hi, I am using the Dropbox SDK V2 - Java and I can connect, list files, and even upload files. However, when I try to download a file, the file that I end up with is empty (0 bytes). I have tried several different files, all of them are small in size. Any ideas or suggestions? Here is the...

Con solo quella parte di codice ho pensato fosse un classico Httpjob. Errore mio.

With only that part of code I thought it was an Httpjob. My fault.

Rispondo sia a Sagenut che a Manfred
Si Manfred io sto gia usando la versione Dropbox V2 V 0.47
Si Sagenut il problema alla fine è che il download ci mette un pochino (qualche secondo)
Potrei forse mettere un flag nell'evento

dbxFiles_DownloadFinished

, che mi avvisa che il file è stato scaricato, ma posso fermare l'esecuzione del codice finchè il flag non è vero.? Con cosa ? Wait For?

I answer to both Sagenut and Manfred
Yes Manfred I am already using the Dropbox V2 V 0.47 version
Yes Sagenut the problem in the end is that the download takes a little bit (a few seconds)
I could perhaps put a flag in the event

dbxFiles_DownloadFinished

,which warns me that the file has been downloaded, but I can stop the execution of the code until the flag is true.? With what ? Wait For?

 

[DonManfred]

which warns me that the file has been downloaded

The Event is raised when a Downloadrequest finished. Successfully or not.
It does not check if a file was downloaded before. YOU neeed to check before downloading whether the file exists and only start the download if not.

 

[Sagenut]

Sperando di non sbagliare di nuovo

Wait for dbxFiles_DownloadFinished

 

[Sabotto]

No. I want to download it regardless if it exists or not. The problem is that after I downloaded it, I have to stop the execution of the code until the file has been downloaded completely (it takes 1-2 seconds). However I solved it by looping the Size control.
About this:

File.exists (FolderDropBox, Filename)

doesn't work with dropbox folders and files. he always tells me they don't exist
Wait For dbxFiles_DownloadFinished doesn't work well in my case

 

[DonManfred]

I have to stop the execution of the code until the file has been downloaded completely (it takes 1-2 seconds).

make the downloadsub a resumeable sub and use wait for to wait for the sub finished.

[B4X] Resumable Subs - Sleep / Wait For

New video tutorial: Resumable subs is a new feature added in B4J v5.50 / B4i v4.00 / B4A v7.00. It dramatically simplifies the handling of asynchronous tasks. (This feature is a variant of stackless coroutines.) The special feature of resumable subs is that they can be paused, without...

[B4X] Resumable subs that return values (ResumableSub)

Remember that that a call to Sleep or Wait For in a resumable sub causes the code flow to return to the parent. Example: Sub Button1_Click Sum(1, 2) Log("after sum") End Sub Sub Sum(a As Int, b As Int) Sleep(100) 'this will cause the code flow to return to the parent Log(a + b) End Sub...

Wait For dbxFiles_DownloadFinished doesn't work well in my case

Start with fixing this problem first. Start with understanding how resumeablesubs are working and how to use them. See my links above.

Why it does not work well in your case?
