Palindrome Checker in ASP.NET

Here is a simple program that I wrote that will ask the user to give a string and then our program will check if the given string is a Palindrome or Not a Palindrome using VB.NET as my programming language and ASP.NET as my web development SDK framework. I hope you will find my work useful. Thank you.

Addition of Two Numbers Using ASP.NET

In this article I would like to share with you a sample program that I wrote using ASP.NET and VB.NET to compute the sum of the two numbers. Actually this is the first time I wrote an ASP.NET application in my entire programming career it is very easy to write one it only takes some dedication and patience to accomplish one. I hope you like my work. Thank you.

Selection Sort in Turbo Pascal

A program that I wrote using Pascal as my programming language that will ask the user how many items to be sorted and then our program will display the original arrangement of the numbers and finally it will display the sorted arrangement of numbers on our screen. I am using selection sort algorithm to sort the given numbers by our user. I am using Turbo Pascal for Windows as my programming environment. I hope you will find my work useful. Thank you.
