I have to connect to a db using adodb (which i select from the references). I have to retrieve the car models from the database and bind them to a listbox. I am not sure how to proceed and I can't find any articles on ADO with .net and data binding.
Here is the code that i tried but it only retrieves the car model for the specified id. If I delete the id it doesn't work. Also it writes the car model in the listbox vertically such as:
Imports System.Data
Imports ADODB
Imports System.Data.OleDb

Public Class listboxADO
Inherits System.Web.UI.Page

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
If Not Page.IsPostBack Then

Dim cn As New ADODB.Connection
cn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("/database/duVehicles.mdb"))
Dim rs As New ADODB.Recordset
rs.Open("Select * from cats where car_id=1", cn)

Dim strCat As String

strCat = rs.Fields.Item("cat_NAME").Value

End If
List1.DataSource = strCat
List1.SelectedIndex = 0

The first question that needs asking is why are you using ADO with .NET? It uses COM interop, which will slow your app way down. And is hard to use, since you can't use .NET's data binding features with it.

What is returned in the cat_NAME field? You're reading that value to a string variable and then assigning it to the DataSource property. That's not going to work. Do you really only want to add a single item to the list? And what kind of object is List1?

Does .NET map calls for ADO to ADO.NET?
Hello,We are trying to troubleshoot some DB problems from COM objects that call ADO. I heard that when ADO is loaded inside of a COM object by a .NET app, that .NET intercepts the call and re-maps those calls over to ADO.NET. This seems untrue to me, given the nature of ADO.NET being a totally separate technology.Does anyone know for sure whether this does or does not occur?The problem we are seeing is actually almost identical in symptoms to this:"FIX: Data Queries Sporadically Return Empty Recordsets" Literally, this is what...

Where is the ADO.NET Sybase driver for .NET 1.1 and .Net 2.0?
Hi All Does anyone know where I can get the Sybase drivers for ADO.NET for both versions, 1.1 and 2.0/3.0? Cheers Chris Burrell Hi Chris, There is no release of ASE ADO.NET Provider 2.0 (I assume you refer to ASE provider, not ASA - if ASA please port to sybase.public.sqlanywhere.general). For the 1.1 Provider: It is available in the ASE SDK for windows or the PC Client CDRom included with ASE product. On the SDK its available as 12.5.1 and 15.0 On ASE PC Client I think 12.5.1 is part of ASE 12.5.X and 15.0 is part of ASE 15.X 2.0 provider should release som...
