Assignment 6 –More Looping

100 points

Assigned: 10/11/2006

Due: 10/18/2006 at the start of class

Pre-Lab (Do Before Lab):  Bring a new disk. Plan out tasks, objects, and events needed for program. Plan out major pseudocode

Main Assignment:

We’re going to implement a simplified “craps” game. We will only use one kind of bet that can be made in craps – see below. Show how each game goes (details) in a rich text box. Keep a running tally of wins and losses in text boxes (read-only of course) or labels.

Provide capabilities for Playing a game, resetting - clearing the results to start again, and to exit.

Hand in:

• Floppy disk with an entire folder containing all files related to the project.  Please set the name of the project to something other than the default name (WindowsApplication1, …). Use Windows to copy the whole folder, instead of trying to “Save As”.
• Print out of your code.

Miscellaneous:

· The form of craps we are playing goes by the following rules:

Roll

· 7 or 11 wins

· 2,3, or 12 loses

· Anything else – becomes “point” – new target

After that

· 7 – loses

· Point – wins

· Anything else – keep rolling

Any questions, please ask!!! Even if you’ve played different variations, the above is what we’re playing here.

• In this assignment, when “keep rolling” don’t rely on the user doing anything – keep rolling for them
• Roll dice with a “pseudo” random number generation, as we have done in class.
• As dice are rolled, show results in the rich text box (what the individual dice were, and the total)
• When there is a winner or loser, notify the user and update the tally of wins/ losses
• When the user plays again, make sure to clear the rich text box so that previous dice rolls are not in the way.
• You must turn on Option Explicit and Option Strict.
• To add items to the rich text box, use richtextboxname.AppendText( a string ). You can build a string out of pieces using “concatenation” . E.g.  “Material: “ & material.toString(“n3”) & ControlChars.NewLine

(The ControlChars.NewLine moves the next info after to a new line). To clear the contents of a list box, use richtextboxname.Clear()

• MAKE SURE YOUR PROGRAM WORKS! (i.e. gets the correct answers). Now that our program is branching and looping, we need to try more examples to make sure they work. Think, “what different possibilities need to be checked?” For each, calculate the correct answer by hand and see if your program gets it!
• Make sure you save your work before running your program. It is possible that an “infinite loop” could have to be terminated. Usually that will be ok, but if you ever had to kill VB using the task manager you could lose unsaved work.
• Put YOUR NAME, e-mail address, date, and purpose of the program in comments at the beginning of the program.
• You MUST include comments that explain your program in order to get full credit.
• Remember to use meaningful variable names, and indent to show the structure of the program (VB usually does this correctly).
• Put your name on the form as a Label or as part of the form title.
• Try to use good user interface design. Make clear what user needs to do and what the answers mean.
