    Dim cat As New ADOX.Catalog
    Dim lngPerm As Long

    ' Opens a connection to the northwind database
    ' using the Microsoft Jet 4.0 provider
    cnn.Provider = "Microsoft.Jet.OLEDB.4.0"
    cnn.Open "data source=c:\Program Files\" & _
        "Microsoft Office\Office\Samples\Northwind.mdb;" & _
        "jet oledb:system database=" & _
        "c:\Program Files\Microsoft Office\Office\system.mdw"

    Set cat.ActiveConnection = cnn

    ' Retrieve original permissions
    lngPerm = cat.Users("admin").GetPermissions("Orders", adPermObjTable)
    Debug.Print "Original permissions: " & Str(lngPerm)
    
    ' Revoke all permissions
    cat.Users("admin").SetPermissions "Orders", adPermObjTable, _
        adAccessRevoke, adRightFull
    
    ' Display permissions
    Debug.Print "Revoked permissions: " & _
        Str(cat.Users("admin").GetPermissions("Orders", adPermObjTable))
    
    ' Give the Admin user full rights on the orders object
    cat.Users("admin").SetPermissions "Orders", adPermObjTable, _
        adAccessSet, adRightFull

    ' Display permissions
    Debug.Print "Full permissions: " & _
        Str(cat.Users("admin").GetPermissions("Orders", adPermObjTable))

    ' Restore original permissions
    cat.Users("admin").SetPermissions "Orders", adPermObjTable, _
        adAccessSet, lngPerm

    ' Display permissions
    Debug.Print "Final permissions: " & _
        Str(cat.Users("admin").GetPermissions("Orders", adPermObjTable))
