Sub Main()
    On Error GoTo ViewTextError

    Dim cnn As New ADODB.Connection
    Dim cat As New ADOX.Catalog
    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
    Set cat.Views("AllCustomers").Command = cmd
    
    'Clean up
    cnn.Close
    Set cat = Nothing
    Set cmd = Nothing
    Set cnn = Nothing
    Exit Sub

ViewTextError:

    Set cat = Nothing
    Set cmd = Nothing
    
    If Not cnn Is Nothing Then
        If cnn.State = adStateOpen Then cnn.Close
    End If
    Set cnn = Nothing
    
    If Err <> 0 Then
        MsgBox Err.Source & "-->" & Err.Description, , "Error"
