Login Security in Visual Basic 6

Visual Basic 6 is one of the most popular visual programming language developed by Microsoft way back in 1998 ever since this language used in many applications such as business application programs I have developed many customized programs in Visual Basic 6 throughout in my career however I gradually move on in web programming in PHP and MySQL because of the demand and ever changing needs of my clients. Anyway in this article I would like to share with you a login security system that I wrote in Visual Basic 6 and Microsoft Access that will protect your database application against unauthorized access I called this program login security system.

Bubble Sort in Java Program

In this article I would like to share with you one of the most common sorting algorithm used in computer science it is called bubble sort. Basically we use sorting to arrange the values in ascending or descending order. What our program does is to ask the user how many items to be sorted and then our program will ask the user to enter a series of values. After which our program will display the original values and it will display the ascending and descending order of values after it is processed by our program using bubble sort algorithm.
