This tutorial will teach you on how to create a simple Image Converter using Visual Basic. This program is able to change the image format like converting JPEG format to PNG format. To build this program open Visual Basic and create a new project and name it as Image Converter.

Introduction: So this tutorial is going to be on how to make a simple script to check if a website is on-line or not. Steps of Creation: Step 1: First let's import System.IO and System.Net:

In this tutorial we will learn to create a simple face(only eyes) which change when sleep button or wakeup button is clicked. This Application has two JButtons and a Panel for displaying the face. This Application handles Action Events for the buttons. In all we will create three class to make the design simple and clear.

Part 1: Creating a Class FacePanel for drawing face

Step 1: This class is used to draw the face based on whether the face is awake or asleep. For that we require a boolean variable awake which is set false initialy.

Applets are programs which run on web browser and Application means the stand alone program in a computer. In Java we can convert Applets to Application and Application to Applet.

Step 1: Change init() method's name to the constructor. Java Applets contains init() method which is used for initializing the applet, this method should be changed to constructor for that class.

This tutorial is a continuation of Part III: Update and Delete Specific Data in MySQL Database using Visual Basic. Net. But this time we're going to focus on how we can improve the design of our existing code using Code Refactoring. Refactoring is the process of changing a software system in such a way that it hasn't altered the external behavior of the code, yet improves its internal structure.

Introduction: Today we will be making a simple program to extract all emails within a web page source. We will be doing it manually rather than using Regex. Notes: This will require a webpage which contains one or more emails.

Introduction

This tutorial is about creating simple calculator which performs only four operations. For creating a simple Calculator we require two JTextFields where the user can enter two numbers, four JButton for four operations namely addition, subtraction,multiplication and division, a JLabel for displaying the result.

Implementation

Step 1: Creating a class which extends JFrame because we are going to create an Application. After this we have to define the constructor of the class as follows. Super() is used to give title to the frame.
