' BeginCreateProcedureVB  
Sub Main()  
    On Error GoTo CreateProcedureError  
  
    Dim cnn As New ADODB.Connection  
    Dim cmd As New ADODB.Command  
    Dim prm As ADODB.Parameter  
    Dim cat As New ADOX.Catalog  
  
    ' Open the Connection  
    cnn.Open _  
        "Provider='Microsoft.Jet.OLEDB.4.0';" & _  
        "Data Source='Northwind.mdb';"  
  
    ' Create the parameterized command (Microsoft Jet specific)  
    Set cmd.ActiveConnection = cnn  
    cmd.CommandText = "PARAMETERS [CustId] Text;" & _  
    "Select * From Customers Where CustomerId = [CustId]"  
  
    ' Open the Catalog  
    Set cat.ActiveConnection = cnn  
  
    ' Create the new Procedure  
    cat.Procedures.Append "CustomerById", cmd  
  
    'Clean  
    cnn.Close  
    Set cat = Nothing  
    Set cmd = Nothing  
    Set cnn = Nothing  
    Exit Sub  
  
CreateProcedureError:  
    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"  
    End If
