The Donut Shoppe sells four varieties of doughnuts: Glazed (1.05), Sugar (1.05), Chocolate (1.25), and Filled (1.50). It also sells regular coffee (1.50) and cappuccino (2.75). The store manager wants you to create an application that displays a customers subtotal, 6% sales tax, and total due. Create a Windows Forms application. Use the following names for the project and solution, respectively: Donut Project and Donut Solution. Save the application in the VB2017\Chap06 folder. Create the interface shown in Figure 6-57. When coding the application, use one independent Sub procedure to determine the subtotal, which is the total cost without the sales tax. Use a function to determine the sales tax. Use an event-handling Sub procedure to clear the output. Save the solution and then start and test the application.
In Chapter 2, you created an interactive application named MarshallsRevenue, and in Chapter 3 you created a GUI version of the application named MarshallsRevenueGUI. The programs prompt a user for the number of interior and exterior murals scheduled to be painted during the next month by Marshalls Murals. Next, the programs compute the expected revenue for each type of mural when interior murals cost $500 each and exterior murals cost $750 each. The applications also display the total expected revenue and a statement that indicates whether more interior murals are scheduled than exterior ones. Now, modify one or both of the applications to accept a numeric value for the month being scheduled and to modify the pricing as follows: Because of uncertain weather conditions, exterior murals cannot be painted in December through February, so change the number of exterior murals to 0 for those months. Marshall prefers to paint exterior murals in April, May, September, and October. To encourage business, he charges only $699 for an exterior mural during those months. Murals in other months continue to cost $750. Marshall prefers to paint interior murals in July and August, so he charges only 9450 for an interior mural during those months. Murals in other months continue to cost $500.
In Chapter 2, you created a program for Marshalls Murals that prompts a user for the number of interior and exterior murals scheduled to be painted during the next month. The program computes the expected revenue for each type of mural when interior murals cost $500 each and exterior murals cost $750 each. The application should display, by mural type, the number of murals ordered, the cost for each type, and a subtotal. The application also displays the total expected revenue and a statement that indicates whether more interior murals are scheduled than exterior ones. Now create an interactive GUI program named MarshallsRevenueGUI that performs all the same tasks.
In Chapter 2, you created an interactive application named GreenvilleRevenue, and in Chapter 3 you created a GUI version of the application named GreenvilleRevenueGUI. The programs prompt a user for the number of contestants entered in this years and last years Greenville Idol competition, and then they display the revenue expected for this years competition if each contestant pays a $25 entrance fee. The programs also display a statement that compares the number of contestants each year. Now, replace that statement with one of the following messages: If the competition has more than twice as many contestants as last year, display The competition is more than twice as big this year! If the competition is bigger than last years but not more than twice as big, display The competition is bigger than ever! If the competition is smaller than last years, display, A tighter race this year! Come out and cast your vote!
Create an application named SalesTransactionDemo that declares several SalesTransaction objects and displays their values and their sum. The SalesTransaction class contains fields for a salesperson name, sales amount, and commission and a readonly field that stores the commission rate. Include three constructors for the class. One constructor accepts values for the name, sales amount, and rate, and when the sales value is set, the constructor computes the commission as sales value times commission rate. The second constructor accepts a name and sales amount, but sets the commission rate to 0. The third constructor accepts a name and sets all the other fields to 0. An overloaded + operator adds the sales values for two SalesTransaction objects.
