2. The Thesis-Select Target System

1. Some Alternative System for Term Project

Person To Person FTP (File transfer protocol)

Messenger: for chatting and transferring file

Calculator

Explorer

Database programming for Our Class: input, output, modify, delete & relation

2. We choose the target system:

Messenger => It’s very useful and interesting for all people day by day

2. The Thesis-Organization

NAME ROLE

Ta Suong Phung

- Definition of the Basic Function- Definition of the System Module- System Analysis & Design (Object Modeling, Funtional Modeling)- Implementation (GUI)- Pilot Open & Testing- Make up for the Weak Points

Lee SunHwa

- Creation of the Conference Records- Definition of the Process- Definition of the System Module- System Analysis & Design (Dynamic Modeling)- Pilot Open & Testing- List of the Problem- User’s Manual

Kim ChangBong

- Definition of the Project Process - System Analysis & Design (Dynamic Modeling)- GUI & D/B Design- Implementation (Function & Module)- Upgrade of the System


Page 8

2. The Thesis-Basic Function

1. Basic Function of Messenger Programming

Chatting: group chat or single chat

Send & Receive file

Show Webcam

Voice chat

Connect to blog, mail...

2. For limited time, we just focus on 2 main basic function

Chatting: single chat

Send & Receive file


Page 9

3. Analysis of the System-Running Process

Run Messenger Program

Register Friend list: ID, IP, description

Double Click on the Friend Name

New window appear

Connect to the friend

Chatting

Transfer file (if needed)

Close the window (end of chatting)


Page 10

3. Analysis of the System-System Module

For a messenger programming, we need some system module:

Manager List

State check

Chatting Module

Transfer Module

Open

Select file

Sender

Check result


Page 11

3. Analysis of the System-Selection of the Compiler

We have developed our Team Project Program using C++ with .Net

There are some reason as follows

Team Member have not experience with JAVA

We have message source that developed C++

C++ provide with excellent function for CLASS Definition

Member Function and Member Variables

OOP (Object Orient Programming)

Visual GUI

Class Management with Tree Structure


Page 12

4. Design of the System –System Modeling(Object)

Identify Object:

Path

Messenger Management


Page 13


Data dictionary:

User: the person directly using the messenger programming

IP: the IP address for connecting to Internet ID: the user name in the messenger program Friend List: the list of friend for each ID user name File transfer: the file needed to transfer between

the user and friend Path: the address of the file Messenger Management: control the messenger list

(delete or add friend) Chatting conversation: the content of chatting Chatting sentence: sentence in the content of

chatting Word: each chatting sentence composes of many words

6. System Open–List of the Problems

MF71D.DLL does not exist on Ta suong Phung’s Computer(English Windows)

Solution : - Change compile option (Dynamic Link Library Static)- Copy MF71D.DLL file to same directory with *.exe

After change compile Option, Some Function dose not working as follow

Can’t control Friend Function Program Down

Solution : 1. Change compile option (Dynamic Link Library & Debug)2. Copy MF71D.DLL file to same directory with *.exe


Page 38

6. System Open–List of the Problems

In Chatting Window, Input some word and enter keyboard then friend just can see blank space

Solution : 1. Change Action State : Read Only2. Prevent “Enter Event” in

the chatting window

Just see word!!

CONCLUSION

Objective of term project: base on the theory of Object-Oriented Modeling and Design, make the model for implementation.

Targeted model: messenger programming

Analysis and Design the model through:Object ModelingDynamic ModelingFunctional Modeling

Implementation: using C++

Because of the limited of time, our model still has some small problem needed to be improved in further.
