How to Retrieve and Save Data using TextBox Control
This tutorial is part of Database Programming Made Easy Series.
In this tutorial you will learn in different ways on how to retrieve and save data using textbox control.
First we retrieve the data using Data Readers and save it back using ExecuteNonQuery.
Second we will use Dataset and Data Adapter. The same output but with different approach.

Windows Form
This tutorial is part of Database Programming Made Easy Series.
Without Windows Forms your application may look like a DOS application, running in a black and white screen without a Graphical User Interface.
This tutorial will discuss on how to use different controls like TextBox, Label, ComboBox, Button, CheckBox, and finally the ListView Control to access data from our database.
Program Bugs
First of all, I would like to thanks those who reported some bugs on my program particularly on the tutorial called “ How to Connect to a Database and Add/Update/Delete Record“ .

I hope you bear with
How to Retrieve Data

Retrieving data in Visual Basic .NET is now become easy compare to VB 6.0. In VB .NET you will have the privileged of modifying a data in offline mode.
How to Modify Data
This tutorial is part of Database Programming Made Easy Series.
Before, I'm even wondering how to modify data in Visual Basic .NET especially if you used to work with Visual Basic 6.0. Although, there are slight difference with the two versions but I found .NET more interesting compare to VB 6.0.
