LAN Using Visual Basic: Text Messages and Video Conferencing

Project Objective The objective of this project is to implement sending and receiving text messages and video conferencing on LAN using Visual Basic. It provides functionality that enables classes to use a default application framework. Once the frame work is able to do sending and receiving messages and video conferencing on LAN, the project can be extended in future for developing audio chat as well. Two users are able to chat by entering each others’ IP addresses. Users can easily add and delete contacts from their contact list. Users can accept and reject invitations or requests of video chat. Since the only form of authentication is enabling the recipient to accept chat request, this application is not very secure to use on the Internet. But, this application is intended to be used inside a LAN where users are known and trusted.
