If you didn't intend to execute a command which return a table as a result,you should use another way. NET there are two modes, namely, the connected mode and the disconnected mode.
In your code,i found that you hadn't opened your connection before executed a command,so you probably couldn't connect to the database. I have a small attached program that clear your confuse. At contrast of the ADO plus where the connected mode is only connected , In the ADO.
can anyone please help me in modifying/correcting the the name of my access database is Book CSharp with a table name Books.

The best way normally to start learning how to make such systems is to learn basic CRUD with database. We assume that you can create a ms access database. You then specify the path to the database in the connection string in our code. Ole Db Public Class Form1 'GLOBAL DECLARATIONS Dim con String As String = "Provider=Microsoft. OLEDB.4.0; Data Source=C:/Users/Sedan/Documents/Data Bases/people DB.mdb;" Dim con As Ole Db Connection = New Ole Db Connection(con String) Dim cmd As Ole Db Command Dim adapter As Ole Db Data Adapter Dim dt As Data Table = New Data Table() Private Sub Form1_Load(sender As Object, e As Event Args) Handles My Base. Click Retrieve() End Sub Private Sub update Btn_Click(sender As Object, e As Event Args) Handles update Btn. Close() Retrieve() Catch ex As Exception Msg Box(ex. Close() End Try End Sub Private Sub Cleartext Boxes() name Txt. Click Add() End Sub Private Sub retrieve Btn_Click(sender As Object, e As Event Args) Handles retrieve Btn. i am a little bit confused if have to use a connection string and a data Adapter to get a connection to the database everytime i want to perform each action like updating, deleting e.t.c and please how do i write the cade for the update,delete,edit and insert statements as i am a little bit new to ADO.
