Introduction

There is a lot of different parking system in the world whereby our objective of

the whole project is to produce a different type of parking system for the management of

UCTI as the construction of a three storey car park has completed which can

accommodate 90 cars in total and each level would have 30 parking spaces. Students

would be able to rent a parking lot by using this parking system. Each of the group

members Eugene Chan Zhirong, Foo Shu Ying and Lim Yi Sing has their own task of

work.

This includes producing the registration system to handle the registration of

students for each available car park for each semester by registering their student ID, car

number, and date of registration and so on. After that, we would also need to set the

duration of the car park for the student to park at their particular spot for 150 days by

locating the parking space ID. Each student’s information would be stored in a database

table created by us using Visual Basic framework and SQL database structure. By

creating the database, we would also create relationships between each of the different

tables which include students, parking spaces as well as users. This parking system would

be used by the parking administrative office to register students who wishes to park at the

car park.

User Manual

User Login

First of all, user would need to go through the login page in order to log into the

application main page. The initial first start-up of the program should be empty database.

User will need to register in order to login. If the database is empty and there are no

registered users in the database, the login page would be as follow:

As shown in the above picture, the “Cancel” button would automatically be

changed to “Register” button. After the first user register, the first registered user would

be automatically assigned as the Admin.

20

User Register

It is advisable to complete the recruitment system before starting the access of the

system. Recruitment can be done by clicking the add button and fill in the information

specified. Once the users clicked save, the information that input by the user will store

into the database.

Please note that only administrator has the right to access the staff registration and

check it. You may also browse through the record and update the record that has been

outdated or delete the information that is no longer needed.

21

Forget Password

If the user forgotten his/her password, the user are allowed to click on the

“Forgotten Username/Password”, and then the user are allow to input his/her email

address. After that, an email will be send to the individuals email.

22

Change Password

Password changing for the admin user is possible in this application. If the current

user wants to change his/her password, the user would only need to go to the toolbar and

choose admin control to change password. However, if the user wants to change the other

user password, the current would need to go to the admin control and choose edit all

admin, after that, he/she would need to click on set password in order to change, but that

doesn’t mean the user are allow to change the password straight away, he/she would need

to input the old password first and then input the new password in order to change.

23

Admin Edit

As for editing the admin, user are allow to edit the admin through the toolbar and

choosing “Edit all admin”, after that, a window will pop up as “AdminEdit”. In this

window, users are allowed to add new user, edit user and delete the user. However, the

current user would not be able to delete his/her record as the admin or moderator.

24

Student Register

Before you are able to make any registration, you must first choose the parking lot

from the MDI, and then input all the information of the student including Student ID,

First Name, Last Name, Contact Number, E-mail Address and Car Number. After that,

only the student would be able to register.

25

Search

Users are allowed to search the students registered through the database by using

the search form as shown above in order to update the details. User would need to only

input the Student ID of the student, then all the details of the student would be shown in

the group box.

26

Update/Delete

When user want to update the student information, user can update here. User just

need to click the update button, then can update the student information. Besides, user

just clicks the delete button, and then the student information will be deleted.

27

Delete Expired User

When the user is expired, we will use this function to delete it. This is because we

don’t want waste the database space. This can save the database space. When we found

that the database has expired user, we will delete it.

28

Critical Assessment

In our new system, we realize that problem in our new system does exists. One of

the major problems would be the crystal report. All works well when running the

program on the development machine but when the program is deployed to another

computer, the crystal report will not be able to generate. We had tried to solve this

problem, but it seems that there were no solutions to solve this problem.

29

Conclusion

As for our conclusion, we had found that Visual Basic is a very well organized

application. We had learned a lot during producing the parking system using Visual

Basic. As we are the learners of using Visual Basic, we found that in the programming

world, it’s all about creating a program that is stable. However, error do occurs during the

process of creating the program, but we had gone through lots of havocs and trying to

resolve each of the problems that occur during the producing time. It is a very good

experience for us to produce such a program with all our hard work.
