Motivation

A social networking site that allows you to video chat online is the primary inspiration for my project.

I am highly interested in the development of Network Application.

I have interest in Socket programming . This application covers my all area of interest.

Overview of chat application

There are so many chat application exists, but most of them are server/client based application. User have to make profile to user those application

To use Video On LAN Application user do not have to make profile page. Just need to add IP address.

To initiate chat with user it requires users acceptance. IP addresses are saved in contact log file to next time

you start the chat you do not have to add IP address.

Technology

Used VC++.NET MFC Library

Microsoft Foundation Class Library (MFC) is a library that wraps portion of the windows API in C++ classes. Also includes functionality that enables MFC to use a default allocation framework.

Project Implementation

Map all buttons and menu items corresponding to the function. Add contact and Delete contact. Connecting to a Remote System. Sending text data. Start Host CAM. Stop Host CAM. Invite to view My CAM. Request to view Guest CAM. Stop viewing Guest CAM. Disconnecting from Remote System. Exit the Application.
