Passed and Failed Grade Counter in Java

In this article I would like to share a sample program that will ask the user to enter a series of grades and then our program will count and display the passing and failing grades among students in a class using one dimensional array in Java.

If you have some questions about programming, about my work please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com. People here in the Philippines can contact me at  my mobile number 09173084360.

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.
