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.

Once the user has already acquired the system requirements for running this

machine, we can now prepare the Lottery Digits generator for installation for starters.

PCSO Lottery Digits Generator Setup:

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 .

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.

B.1. CD-RW Installation (Wizard):

1.) From the PCSO Lottery Machine CD-RW, extract zipped

folders into desktop first then the user will see theses icons on the window. They can double click any of the two icons to install the application.

2.) Once double clicked an application warning will show, don‟t feel threatened by that message for that is normal. Ignore the warning and click install.

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!

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.
