Project: the Hall Light Project in Visual Basic

Project 2: The Hall Light Project

Consider the Hall light system that exists in most modern houses. If both switches are on or if both are off, the hall light is off. If one is up and the other is down, the hall light is on. This logic is called an Exclusive Or, commonly abbrieviated as: XOR. In order for the logical expression: A XOR B to be true, either A or B must be true, but not both.

Write a program that will input the state of the two switches and shows a light image that is ON and one that is OFF to tell the user whether the hall light is on or not.

Instructions:

1. As shown in class, open Visual Basic and Create a new project.

2. You are to read the project in the book carefully and translate it into a VB application.

3. Use two buttons for the switches ON/OFF. You can make them graphic if you want, with colors and pictures, but you must at least have the captions change to ON or OFF when they are clicked.

4. You must have a pic box with a picture of a light turned on and another pic box with a picture of a light turned off. Make one of these visible when the light is on, and the other visible when the light is off.

What to turn in:

1. Create a drawing of your application on graph paper.

2. Using the File/Print menu option, print the code and at least 2 screenshots of your running application.

3. Hand in all three items described above on paper, no e-mails, no disks.
