Visual Basic 2010 How to Program Deitel Exercise 5.5 Retail Sales Calculator Application

(Retail Sales Calculator Application) An online retailer sells five products whose retail prices are as follows: Product 1, $2.98; product 2, $4.50; product 3, $9.98; product 4, $4.49 and product 5, $6.87. Write an application that reads a series of pairs of numbers as follows:

product number;

quantity sold.

Your program should use a Select…Case statement to determine the retail price for each product. It should calculate and display the total retail value of all products sold in an output Label as shown in Fig. 5.21. Keep the total retail value up to date as the user enters values. [Hint: Create instance variables to store the quantity sold of each product so the values are maintained between calls to the event handler.]
