Connect the ”fe” to the encrypted ”be”

I have asked before, but never found a useful solution, so please.

I want to connect the ”fe” to the encrypted ”be”, and I have tried with this
code:
Public Sub OpenDB()
Dim ServerFile As String
Dim db As DAO.Database
Dim ws As DAO.Workspace

Set ws = DBEngine.Workspaces(0)
ServerFile = "d:\home\data\ATR\Tabeller\ATR_be.accdb"
Set db = ws.OpenDatabase(ServerFile, False, False, "MS Access;pwd=be")
‘ db.Close
End Sub
My problem is that I don’t know from where I should call OpenDB when opening
the ”fe”, in order to connect to the ”be” and maintain the connection during
the whole session.
I’m also in doubt if I have to use db.Close.
I'm still new in Access as you may notice :-)
