Hi LucaMs,
thanks for the link. It looks very complex ... I thought there would be a simplier way to do the same as content chosser do.
A "normal" lib which is integrated in B4j would be the thing......
Sub ChooseFile(Open As Boolean) As String
Dim fc As FileChooser
fc.Initialize
fc.InitialDirectory = mFCInitialDirectory
fc.InitialFileName = mFCInitialFileName
If Open Then
fc.Title = "Leggi condizioni"
Else
fc.Title = "Salva condizioni"
End If
