2012 IT418 – C# Programming Project 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

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

Description This is used to enter a draw number that counts a session. This button should be pressed one at a time per draw attempt in a game session. This button should only be pressed after a singular attempt on drawing winning lotto numbers. This button is pressed last after drawing and sorting the winning lotto numbers as it saves those as used in DB.mdb. This button can be pressed whenever the user feels like closing the application. This button is only necessary if a user wants to view technical details about the game system and exit the program. This command is pressed if the user was curious about technical detail of the game system. Press this command to exit. This command is pressed to direct the user on how to use the controls of the PCSO ottery digits generator. About (frmAbout) Pressed whenever the user feels like leaving that message box. Help (form1) Pressed whenever the user feels like leaving the help screen.

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

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

2012 IT418 – C# Programming Project 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.

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!

2012 IT418 – C# Programming Project 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 noobieness 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

desired results.

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

2012 IT418 – C# Programming Project 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

0535 - 0000 – 7999 (I-DIT)

unless it becomes a necessity again someday.
