In our previous tutorial we discuss on how to create a secure registration page using three different approaches.

In our last two articles, we discuss on how to create a registration page using mysql and mysqli extension and how to secure it using mysql_real_escape_string or mysqli_real_escape_string.

This time we will modify our code to use PDO instead of mysql or mysqli extension.

mysqli extension works differently compared to mysql extension. The 'i' stands for improved. Which means that it has some features that cannot be found in mysql extension. There are two approach in using mysqli extension. They are Object Oriented style and Procedural style. If you are migrating your old PHP file to mysqli extension, I prefer you use the procedural style. It's very easy to convert it to mysqli this way. Looking at the example in our previous tutorial.

By secured we mean that we need to sanitize the data that is passed to our script in order to secure the registration of new account or user. There are three different types of connectivity in MySQL. They are: mysql = old MySQL function mysqli = improved MySQL function pdo = using prepared statement Mysql_connect is currently not supported in PHP version 5.5.0.

Unlike DataReader, ExecuteNonQuery function allows you to insert, update, and delete data.

This is a continuation of my other tutorial entitled Display Bios Information using VB.NET, but this time it will display all the hardware information such as Bus,Motherboard,Memory, and Sound in Vb.NET also. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2.
