Odd and Even Number Checker in ASP.NET

Hi there first of all thank you very much for visiting my website. I am very happy that the visitors of my website is growing everyday even though I did not earn any money from this endeavor but I would like to share my passion about programming.

In this article I would like to share with you a sample program that I wrote in Visual Basic NET and ASP.NET I called this program odd and even number checker in ASP.NET. Programming in ASP.NET is very new to me because I am a PHP developer for a long period of time. I find it very easy to create a web application using my existing knowledge in Visual Basic.

What does the program will do is to ask the user to give a number and then our program will determine and check if the given number is odd or even number. The code is very simple and easy to understand. I am using Microsoft Visual Studio 2008 as my working environment in writing this code. I hope you will like my work.

I am currently accepting programming work kindly contact me in the following email address for further details. Thank you.
