B4J Question verify and copy file

Please, post the error msg, since there are no missing parameters in your File.Copy.
(I suppose that the AdditionalJar in your project is correct, with the right path and file name. The sqlite... jar must be in the additional libraries path)

You'll find hereafter the all text of the Main

#Region Project Attributes
#MainFormWidth: 600
#MainFormHeight: 400
#AdditionalJar: sqlite-jdbc-3.7.2
#End Region

Sub Process_Globals
Public db As SQL
Private fx As JFX
Private MainForm As Form
End Sub

Sub AppStart (Form1 As Form, Args() As String)
LoadDatabase

End Sub

Sub LoadDatabase
If Not (File.Exists(File.DirData,"qizine.rsd")) Then
File.Copy(File.DirApp,"qizine.rsd", File.DirData,"qizine.rsd")
End If
db.InitializeSQLite(File.DirData,"qizine.rsd")
End Sub

and a screen copy of the error msg


When I make a new B4J, It work until I saved it.

Thanks in advance

The missing parameter is in File.DirData (see the tip of the command).

Probably you want to do as in B4A, copy from assets to application directory; then you should use:


"qizine.rsd" must be added by Files Manager - Add Files, of course

Ok Thanks but:

The file.DirApp is read only, how should I use it to write into de DB (it's why I used the file.dirData directory)?


-To Giannimimaione thanks but I've already try it and the result is the same "missing parameter

Click to expand...

You're right but you can create a sub dir in DirApp and write there:

Ok

Many thanks for your help
I'll can go further.

I've found the missing parameter.
It's the (AppNameAsString) who as to be after the dirdata. Now with it everything is Ok
