CHAPTER I: DESCRIPTION AND DETAILS OF GAME TO BE SIMULATED

A Lottery Digit Generator Machine for Philippine Charity Sweepstakes

office is the motif of this documentation. Practically, the machine is going to be used

to randomly select winning lottery digit combinations in general for all categories of

the said game. It is going to be digitally composed following the concepts of visual C#

language.

Now, C# is another variant of an Object Oriented Programming

language developed by Microsoft which combines C++ principles into the rich

environment of Visual basic that supports ‘windows-application-tools’.

The computer language is basically kept simple yet can perform as

much tasks as other programming platforms. It was actually designed to be

comprehensible to developers as it still follows through C language concepts.

What sets C# language apart among other programming format is

that, it works with the .NET Framework which provides a comprehensive and

consistent programming model for building applications that have visually stunning

user experiences and at the same time enforces “Simple Object Access Protocol”

(SOAP) which doesn’t require developers to put additional codes for repeating a

behavior in a program.

Thus, C# language is deemed appropriate to design and craft our

PCSO Lottery Digit Generator because of its convenient encryption of syntaxes that

works well with streamlined visuals which make it light to operate.

CHAPTER IV: TESTING

4.1 Test Plan

The PCSO Lottery Digits Generator, of which is essential for drawing

winning numbers for that sort of game, has already completed the development

phase by now. To ensure the quality of this gaming system, a series of test cases

should be done to see if there are any underlying defects to correct in the program.

The machine will be manually tested based on its Physical and Logical

Aspects. Where in, the essential statements and syntaxes will be the data to be

evaluated in this phase.

Basically, there are measures to be observed and they are objectives

that this testing should achieve and are listed below as follows:

To ensure that all the objects in the program are functional.

To see if statements and syntaxes in the program are in accord and

execute commands systematically.

To make sure that the program runs without any errors.

Therefore, it is necessary for the PCSO Lottery Digits Generator to undergo testing

so there will be guarantee that it will run flawlessly. This procedure also helps the

developers to detect errors that have been over looked during the creation stage.

The testing process shall now commence turning on the next page.

CHAPTER V: IMPLEMENTATION

5.1 User Manual

This section of the documentation is compelled to explain to the user the

proper utilization of PCSO Lottery Digits Generator. Again, the purpose of the

machine is to generate winning number combinations for all categories of that game

of luck. Technically, the Lottery system is crafted in C Sharp Programming language

which streamlines items contained in a particular windows form application. This

type of C language can work with robust graphical user interfaces which would need

prerequisites to run. So before we begin with directives on how to operate this lottery

digit generator we should first determine System Requirements for the user to take

note and obtain. The machine is best suited for the later versions of windows which

are XP and 2007 since it is crafted using visual C# 2008 Express Edition.

There are two means of installing the Lottery Digits generator into the user’s desktop

and that would be either a USB device or CD RW that can be either Manual or

Wizard, read ahead for the procedures.

A. USB device installation:

One way to install the PCSO Lottery Digits Generator Machine is via a USB

device or commonly referred to as the flash drive. Initially the developer will

provide the file you will transfer then just follow these quick steps:

1.) Pull out your USB flash drive wherever and plug it in a USB port the

user’s desktop should

automatically recognize

the device and should

automatically direct a

user to its removable

disk drive. Open that

drive.

NOTE: you can manually locate your USB drive on MY COMPUTER!!

2.) Once the USB removable disk drive is opened you will

immediately see the Lotto Folder in there, copy paste that

into your desktop to transfer it .

B. CD-RW Installation (Manual) :

This is another method in installing the PCSO Lottery Digits Generator into the user’s

desktop it is also a simple task of transferring a file. The CD RW will be provided by

the developer initially upon request by the way.

1.) Feed the PCSO lottery digits generator CD-RW into the computers CD ROM

drive. Wait for it to load then it will prompt the user to open a folder.

NOTE: The user can manually open the CDROM local drive in MY

COMPUTER too.

2.) Once the CDROM local drive is opened the user will see a zipped Lotto folder

Copy and paste then right click >> extract that into the desktop and taddah!!

The system is transferred.

After the installation we shall proceed to opening then operating the Lottery Machine.

Store Number Button Usage:

Let’s say, the user has

already drawn winning

lottery digits and stored it in a

database using the Store

Digits button in the

machine’s interface.

A Message box that

states the lottery digits are stored into a database

so they will be marked as USED. When this

happens the

user can view

the numbers stored in a database so they can take note of it. To do that they should

go to the database explorer in the visual studio interface of the lottery solution then

expand the table folder then right click on the UsedNums table and click retrieve

data. The stored digits will be displayed in that tables field right away

CHAPTER VI: CONCLUSION

6.1 Strengths

The PCSO Lottery Digits Machine is now fully operational and has surpassed

the development and trial stages, as stated earlier, following through the discipline of

C# language.

The gaming system holds to its promise as a mechanically efficient tool than

its predecessor as it can now draw numbers from 1 to 66 accurately in textboxes by

assigning them into an array that is then handled by a random selector.

There is an algorithm at the back end of this lottery system to ensure the

credence of the winning number combinations that were drawn by the machine. After

the numbers have been drawn it can be sorted by a button in a descending order to

keep things organized.

What makes this program all the more special is that it has a storage feature

that writes the winning digits drawn into an MS Access Database for the purpose of

eliminating the numbers that have been used.

Finally, the Lottery Machine has been topped off with a label that shows the

current date and time of a draw to chronicle the session. There is also a label that

counts the number of attempts the lottery machine made a draw. Therefore, the

machine is certified marvelous!

6.2 Weaknesses

As much as there are a bundle of good points about the PCSO Lottery

Number Generating Machine there are fault areas in it and blame that to the noobie-

ness of the programmer.

Since the developer is only a student in Informatics Filinvest at this time she

still has a lot more to learn about this branch of information technology but the fact

that she was able to add the important details makes her competent. However,

having the lottery numbers stored in an external database for elimination will trouble

the user to view it in a distant folder where in they constantly have to find that source

file. Generated lottery numbers are not automatically removed from the random

selection so the users will need to consciously note down the numbers used from its

inclusive database and remember that.

6.3 Enhancements

The PCSO lottery machine can improve by adding another feature

which allows users to view the USED lottery winning numbers in a table of a

database in a subform within the machine so they won’t have to leave the program to

check what has been appended in there. Lottery digits that have been drawn should

be deleted automatically when it has been generated so the user won’t have to take

note of the numbers manually and avoid drawing digits many times to achieve

desired results.

CHAPTER VIII: Critical Appraisal

This is where the documentation for PCSO Lottery Generating machine

comes to an end and the developer is asked to write closing remarks and insight

pertaining to the creation of this project.

She would like to impart that it has been enjoyable creating a program in C#

because it is very light and easy to use and much convenient that other C language

formats. It works very well with .NET Framework and employs Simple Object Access

Protocol to keep syntaxes into a minimal. Connecting C# programs into a database is

also very easy accompanied by the database explorer panel as well for supervision.

The developer would like to create more games using the computer

language in the future but unfortunately C# language has been depreciated

according to a mentor and is rarely used these days.

Perhaps the developer can only use C# for recreation and leisure only

unless it becomes a necessity again someday.
