A collection of source codes that I wrote in VB 6.0, ASP.NET, PHP, C#.NET, VB.NET and JAVA in a course of my career as web developer and software engineer that I would like to share to my fellow programmers. Some of the codes here is not my original work that I found over the Internet and Books while I'm learning how to program. I hope you find my work useful in your learning in programming. Please share my work to other people also who interested to learn the basics of web development and programming. Thank you very much and Happy Productive Programming Everyone.

Call Tracer App

Nothing is more annoying than spam calls telling you that you’ve won a trip, car, money, or all three. For most of us, these calls are annoying because we know they are fake and they take up our time having to deal with. For others who may not realize these calls are simply scams, it can cost them something much more valuable than time – security.  There may be the case where we get a call from unknown number or may be number which is not saved in contact list. Call Tracer App is attempting to offer a solution for calls that is just as easy.

Application helps in blocking individual numbers, you can enter the number yourself, select it from your call history or contacts, or you can even block a number series so that you never receive a call ever again.  For ex service provider calls or call starting from “1-800” series. Whenever you get a call from a number not in your contacts, a floating window will appear on your screen that shows the name and location of the caller.

Nowadays, smart phones are being widely used all over the world. This has mainly been due to the features of Android platform such as high flexibility in application, reasonable cost, good durability and user friendly in handling etc. As a result of this, the demand of applications developed in Android platform is increasing.

Hardware & Software requirements:

The project is developed in Java Programming Language by Using the Eclipse integrated Development Environment (IDE). Android Software Development Toolkit (SDK) id used, which includes a variety of custom tools that help us in developing mobile applications on the Android platform. The most important of these are the Android Emulator and the Android Development Tools(ADT) plug in for Eclipse.

  • Java 1.6 runtime
  • integrated development Toolkit
  • Android Development Tools (ADT) plug in for Eclipse
  • Android Emulator
  • Technology: j2me


Due to the growing use of android platform software cell phones, the need of a new and genuine android application is increasing. Now a days, in busy work schedule it’s very difficult to remember unsaved contact numbers or maybe there are few spam calls which is disturbing our work process. The Proposed application will solve all these problems. This app does exactly what it promises and includes some other useful features as well.
