Create an application, using the following names for the solution and project, respectively: Cable Direct Solution and Cable Direct Project. Save the application in the VB2015\Chap07 folder. Create the interface shown in Figure 7-56. The list boxes are named lstPremium and lstConnections. Display numbers from 0 through 20 in the lstPremium control. Display numbers from 0 through 100 in the lstConnections control. The Calculate Total Due button’s Click event procedure should calculate and display a customer’s cable bill. The cable rates are included in Figure 7-56. Business customers must have at least one connection. Use two functions: one to calculate and return the total due for business customers, and one to calculate and return the total due for residential customers. The form’s FormClosing event procedure should verify that the user wants to close the application. Test the application appropriately.
