Using DataReader in VB.NET

In this tutorial we will work with DataReader to retrieve data from a MS Access database.
First of all, a DataReader is an ADO.NET object that provides read-only, forward-only data faster than a DataAdapter. It’s a good choice over the other objects for read-only purpose.
Also, it’s forward-only, means you cant go back to previous data which was accessed. The cursor in DataReader goes from top to button by using the Method Read.

To fill a DataReader with Data, we are going to use the OleDbCommand object and execute the result onto it.
First, we need to create a MS Access Database, with the following table in it:

Table Name: Position
Fileds:
ID, Number, Primary Key
Position, Text(50)
