PROJECT OBJECTIVES
After completing this project, you should be able to:
- Write programs in Visual Basic while being guided by the six steps of the program development cycle: analyze the problem, design a solution, choose the interface, write code, test and debug your solution, and document code.
- Write Visual Basic programs that use the If and Select decisionmaking blocks.
- Develop Visual Basic applications that incorporate "conditional" or True/False statements that "steer" the decision or data flow of the application.
PROJECT DESCRIPTION
The Programming Project provides you with a chance to develop and display your computer programming skills using Visual Basic. The project consists of four (4) programming problems based on programming projects in your textbook. For each problem you will apply the six steps of the program development cycle and submit a document detailing your work as well as the Visual Basic code you write.
Programming Problem 1: Medical Rentals for Patients
Nutritional Associates of New Jersey offers a rental service for patients of the practice. Full day rentals cost oneandahalf times halfday rentals. Write a program that displays the information provided in Table 1 below in a list box when an appropriate button is clicked on and displays a bill in another list box based on the item number and time period chosen by a patient. The bill should include a $30.00 deposit.

Programming Problem 2: Billing Report
Nutritional Associates of New Jersey is in need of a brief billing report for patients. Write a program to generate a patient bill from the patient billing items found in Table 2 below. Use the form in Figure 4.62 of the Visual Basic text as a model, and write the program so that each group box is invisible and becomes visible only when its corresponding check box is checked. After the button is clicked, the amount of the bill should be calculated.
Note: The Checked property of the first radio button in each group should be set to True in its Properties window. This guarantees that a selection is made in each visible group box. Of course when the bill is calculated, only the visible group boxes should be considered; see Figure 4.63 in the Visual Basic text.

Programming Problem 3: Supply Orders
Nutritional Associates of New Jersey needs to place purchase orders for all rental equipment and all patient journals. The medical supply vendor provides the following equipment to Nutritional Associates:
1. Blood pressure monitor kits @ $129.00
2. Heart monitor kits @ $95.00
3. Activity monitor @ $109.00
4. Food intake journal @ $4.99
5. Food intake and activity journal @ $9.99
All items purchased by Nutritional Associates of New Jersey are charged a 7% sales tax rate.
Write a program to create an invoice to the supplier for individual patient supply orders (see Figure 5.40 in the Visual Basic text for a model). After the user enters the data on the left side of Figure 5.40, the user can display an invoice in a list box by pressing the Process Order button. The user can click the Clear Order Form button to clear all text boxes and the list box, and can click on the Quit button to exit the program.
The invoice number consists of the capital letters "NA" followed by a "-" and then the capitalized first two letters of the customer's last name followed by the last four digits of the zip code. The customer name is input with the last name first, followed by a comma, a space, and then the first name. However, the name is displayed in the invoice in the proper order. Take note of the data entry box for City, State, Zip. The user will enter the city name, followed by a comma, the state name, followed by a comma, and finally the zip code.
The generation of the invoice number and the reordering of the first and last names should be carried out by Function procedures. The invoice should include the following: Nutritional Associates of NJ (Patient Name: first last) as the name header.
Programming Problem 4: Caffeine Absorption
Nutritional Associates of New Jersey stresses to their patients the effects of caffeine on the body. After caffeine is absorbed into the body, 13% is eliminated from the body each hour. Assume a person drinks an 8oz cup of brewed coffee containing 130 mg of caffeine, and the caffeine is absorbed immediately into the body. Write a program to compute the following values. See Figure 6.64 in the Visual Basic text.
a. The number of hours required until 65 mg (onehalf the original amount) remain in the body.
b. The amount of caffeine in the body 24 hours after the person drinks the coffee.
c. Suppose the person drinks a cup of coffee at 7:00 a.m. and then drinks a cup of coffee at the end of each hour until 7:00 a.m. the next day. How much caffeine will be in the body at the end of the 24 hours?
