    Dim cmd As New ADODB.Command

    ' Open the Connection
    cnn.Open _
        "Provider='Microsoft.Jet.OLEDB.4.0';" & _
        "Data Source='c:\Program Files\Microsoft Office\" & _
        "Office\Samples\Northwind.mdb';"
    
    ' Open the catalog
    Set cat.ActiveConnection = cnn
    
    ' Get the command
    Set cmd = cat.Views("AllCustomers").Command
    
    ' Update the CommandText of the Command
    cmd.CommandText = _
    "Select CustomerId, CompanyName, ContactName From Customers"
    
    ' Update the View
