Hi,

I am new to xojo cloud. And I don’t know how to find bugs with xojo cloud…  
I am use to System.DebugLog but when I read the logs on the logs folder I don’t retrieve anything concerning my App DebugLog?

Thanks

Chris

Hi Chris - If you control the log file, I would put it in:

SpecialFolder.SharedDocuments

Thanks Jason for your advice, I wrote my own debug\_log

```auto
Try
  // Accéder au dossier SharedDocuments
  Dim logFile As FolderItem = SpecialFolder.SharedDocuments.Child("debug_log.txt")
  
  // Ouvrir ou créer le fichier pour l'écriture en mode append
  If logFile <> Nil Then
    Dim outputStream As TextOutputStream
    If logFile.Exists Then
      outputStream = TextOutputStream.Append(logFile) // Ajouter au fichier existant
    Else
      outputStream = TextOutputStream.Create(logFile) // Créer un nouveau fichier
    End If
    
    // Écrire la date/heure et le message de log
    outputStream.WriteLine(DateTime.Now.ToString + " - " + logMessage)
    
    // Fermer le flux pour sauvegarder les changements
    outputStream.Close
  End If
Catch e As IOException
  // Gérer une éventuelle erreur d'I/O
  System.DebugLog("Erreur lors de l'écriture dans le log: " + e.Message)
End Try

```

Works great, I get the log in shared\_document on xojo cloud
