ACKNOWLEDGEMENT.Stranchat would not have been possible without the kind support and help of many individuals. We would like to extend our sincere thanks to all of them.We are thankful to Mr.S.Sarvanann for his guidance and constant supervision as well as for providing necessary information regarding the project and for his support in completing the project. helped us in the completion of this project.Our thanks and appreciation also goes to all the people who have willingly helped us with all their abilities.Last but not the least, a special and a sincere thanks to the Christ University Lab administrators and the lab staff for allowing us to use the systems in complete freedom and supplying us with all the software needed and their technical support.The project would not have been possible without the contribution, support and guidance of every individual mentioned above.

ABSTRACTThe project,title STRANCHAT is a simple,chat application. Our Project is based on connecting people from various places around the world. As the name suggests, in random chat people sharing the same field of interest can connect and talk randomly. To begin with, the person has to sign up providing with the basic information. It helps in making new friends sharing knowledge clarifying doubts etc. The application provides various categories through which we can select and interact & communicate according to their personal choice. The person can connect and disconnect as and when needed.The aim of building such a website is to help socially challenged people in interacting to people just on random terms. We do provide the user with 2 options while using our website. In the categories section the user is allowed to select from a range of options. He/She will thus be chatting to some random person on the opposite side with the common field of interest.The Random Chat is not based on categories. Its just getting connected to random people whom we dont know anything about and building a connection to them.

1. INTRODUCTION1.1 OVERVIEW OF THE SYSTEMOur Project is based on connecting people from various places around the world. As the name suggests, in random chat people sharing the same field of interest can connect and talk randomly. To begin with, the person has to sign up providing with the basic information. It helps in making new friends sharing knowledge clarifying doubts etc. The application provides various categories through which we can select and interact & communicate according to their personal choice. The person can connect and disconnect as and when needed.The aim of building such a website is to help socially challenged people in interacting to people just on random terms. We do provide the user with 2 options while using our website. 1) Categories 2) Random

In the categories section the user is allowed to select from a range of options. He/She will thus be chatting to some random person on the opposite side with the common field of interest.

The Random Chat is not based on categories. Its just getting connected to random people whom we dont know anything about and building a connection to them.

2. SYSTEM ANALYSIS2.1 EXISTING SYSTEMThe current system does provide us with the random chat option thus connecting us to anyone throughout the globe (in other words: A STRANGER).

LIMITATIONS: The user has no clue of the person he/she is interacting with. There is no such information given. It does not have categories. Not user friendly. No such future contact can be maintained with the other person.

2.2 PROPOSED SYSTEMThis website stranchat.com is for those who find difficulty in socializing. In this website we are adding more features such as sending a friend request to the stranger if you found him/her interesting. We are providing the user with categories through which he can talk to the opposite person on the common topic of interest.

BENEFITS OF THE PROPOSED SYSTEM: Categories option does help the user to chat on common topics of interest. One can keep in touch on the website itself by sending a friend request to the opposite user. More of a user friendly website. Helps the shy and the non-socializing people improve their socializing and communication skills. You can have a complete view of the profile of the user whom you are currently connected to.

2.3 LITERATURE REVIEWBooks:[1] We used this book to gain a basic understanding of the new language we had to learn, C#. It also provided a good introduction to the .NET Framework and programming using Visual Studio.[2] We learnt how to make a windows application using c# and oracle as our basic database and how to connect the database with the application.Websites:We also used a number of websites for tutorials and error resolution in our programming endeavours for this project. The following are the major websites we used:[1] C# Tutorials taught us the different functions available. [4] We have used this website for error handling and connecting our application to the database 2.4 SOFTWARE TOOLS USEDPlatform Windows 7 and Windows 8Front End- Microsoft Visual Studio 2010Back End- MySQL

6. TESTING6.1 TEST PLAN :Atest strategyis an outline that describes the testing approach of thesoftware development cycle. This includes the testing objective, methods of testing new functions, total time and resources required for the project, and the testing environment.Test strategies describe how the product risks of the stakeholders are mitigated at the test-level, which types of test are to be performed, and which entry and exit criteria apply. They are created based on development design documents. System design documents are primarily used and occasionally, conceptual design documents may be referred to. Design documents describe the functionality of the software to be enabled in the upcoming release. For every stage of development design, a corresponding test strategy should be created to test the new feature sets. There are two methods used in executing test cases: manual and automated. Depending on the nature of the testing, it is usually the case that a combination of manual and automated testing is the best testing method.Types of testing:White box testing: This strategy deals with the internal logic and structure of the code. White box testing is also called as glass, structural, open box or clear box testing. The tests written based on the white box testing strategy incorporate coverage of the code written, branches, paths, statements andinternal logic of the code etc. In order to implement white box testing, the tester has to deal with the code and hence is needed to possess knowledge of coding and logic i.e. internal workingof the code. White boxtest also needs the tester to look into the code and find out which unit/statement/chunk of the code is malfunctioning.Black Box Testing: This is not a type oftesting; it instead is a testing strategy, which does not need any knowledge of internal design or code etc. As thename "black box" suggests, no knowledge of internal logic or code structure isrequired. The types of testing under this strategy are totally based/focused on the testing forrequirements and functionality of thework product/software application. Black box testing is sometimesalso called as "Opaque Testing",

CONCLUSION

Stranchat was really something that made us learn quite a lot. Not just about the coding part that helped us improve our knowledge in coding languages but we also learnt the most important aspect of all: TEAMWORK.

7.1 ADVANTAGES

STRANCHAT, an aid to the people by the people. 1. Here, you need not be thinking much before communicating with others. All you need is a connection that in our case is done with the help of a LAN wire.2. In the 21st century, it would be impossible to stay without communicating. We, the students of BCA 5th Semester break this wall.3. An easy to use application for the user. The application is very much easy to use and the user need not be highly educated to use this app. Developed for the common.4. The interface is user friendly and the forms are too basic and interestingly have a good catchy design.

7.2 LIMITATIONS:1. This project uses sockets. Sockets are used for immediate conversations. It will be difficult for the user actually to get the messages on the screen without refreshing the page.2. The application is small just focused on the chat factor. We havent kept up to the mark of putting it up on the internet.3. The tables and the random thing that was actually the main part will be continued in our next part that is the 6th semester if given a chance.

7.3 FUTURE ENHANCEMENT

1. Implying Html, CSS, Ajax, Sockets we can make this project a web application that will be available on the website in the future.2. The normal chat can thus be used to make talks to random people on the website.3. The security can be improved thus making the user feel secure and relaxed that his information lies in safe hands.
