With the advent of ADO.NET, the .NET Framework lets you work with your data in a paradigm shift. What about those legacy applications which have been written using ADODB? We should approach the approach the common problem of re-using or revitalizing existing ADO code. Any middle-tier made of data access components that internally use ADO and return recordsets to ASP pages can be ported to .NET more easily and progressively.
This article walks you through the usage of ADODB services in .NET application using VB.NET language. The example details the data access using ADODB, fetching recordset, filling ADO.NET dataset from the recordset and binding the same to datagrid for user display.
Step 1:
Create a new VB Projects Windows Application in VS.NET, drag textbox, label, button & datagrid control from the toolbox.
Step 2:
Set reference to MS ADO objects 2.7 library using Project->Add Reference menu item and then select COM tab shown in figure below:

Once you do this, ADO objects are available to .NET code as native classes, thus you should be able to see ADODB namespace.
We need to import the System.Data & System.Data.OleDb
Imports System.Data Imports System.Data.OleDb Imports ADODB
Step 3:
Include following code in the button click event. The sql query will take title as parameter based on user input in the textbox.
Private Sub btnSearchTitles_Click(ByVal sender As Object, ByVal e As System.EventArgs) ' database connection string Dim DBConnection As String = Provider = SQLOLEDB;uid = sa;password = password;database = Pubs;DataSource = local ' sql statment Dim SQL As String = "select title_id,title,type,price from Titles where title like '%" + txtTitles.Text.ToString() + "%' order by title" ' 'create ADODB Connection object Dim Conn As New ADODB.Connection 'create ADODB Recordset object Dim rs As New ADODB.Recordset 'create OleDb Adapter object Dim daTitles As New OleDbDataAdapter ' finally Dataset to store returned recordset Dim dsTitles As New DataSet("Authors") 'open connection with the string as above Conn.Open(DBConnection, "", "", -1) 'execute the query specifying static sursor, batch optimistic locking rs.Open(SQL, DBConnection, ADODB.CursorTypeEnum.adOpenStatic, ADODB.LockTypeEnum.adLockBatchOptimistic, 1) 'use the overloaded version of Fill method which takes recordset as parameter daTitles.Fill(dsTitles, rs, "Tiltes") 'bind datagrid to dataset dataGridTitles.SetDataBinding(dsTitles, "Tiltes") 'close the connection Conn.Close() End Sub 'btnSearchTitles_Click
The result of title search will be displayed as follows:
