Programmatically change the connection of a linked

问题:

I have already referenced other pages for my problem but I still can't get this to work. I feel a bit slow given that I have three examples below and still can't figure this out.

Changing linked table location programatically

Linked table ms access 2010 change connection string

Update an Access linked table to use a UNC path

Here is the code that I am using:

Dim tdf As TableDef
Dim db As Database
Set db = CurrentDb
Set tdf = db.TableDefs("DeviceListT")
tdf.Connect = "ODBC;DATABASE=" & CurrentProject.path _
                               & "\HarmonicProfileDatabase_be.accdb"
tdf.RefreshLink

The problem is that when I run it a window pops up.

I am not exactly sure what I am supposed to do with that nor do I want it to pop up in the first place as I will be giving the ms access files to someone else and they won't know what to do with this window either.

You are using SQL Server references but linking MS Access. For MS Access, you do not need an ODBC link, just refer to DATABASE:

DBFile = CurrentProject.path & "\HarmonicProfileDatabase_be.accdb
''Check the file exists
strFile = Dir(DBFile)
If strFile <> "" Then
    With CurrentDb
        For Each tdf In .TableDefs
            ''Check that this is a linked table
            ''It can be useful to use table of tables instead
            If tdf.Connect Like "*HarmonicProfileDatabase_be.accdb*" Then
                tdf.Connect = ";DATABASE=" & DBFile 
                tdf.RefreshLink
            End If
        Next
    End With
    MsgBox "Link HarmonicProfileDatabase_be.accdb" 
Else
    MsgBox "Problem"
End If

You could also use:

 sConnect = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" _
    & DBFile & ";Jet OLEDB:Database Password=pw;"
