In this exercise, you create an application that calculates a customer's cable bill. Create a Windows Forms application. Use the following names for the project and solution, respectively: Cable Direct Project and Cable Direct Solution. Save the application in the VB$9$e $\backslash$Chapo$6$ folder. $($F$6\mathrm{.}1,$ F$6\mathrm{.}3,$ F$6\mathrm{.}5,$ A$6\mathrm{.}4,$ A$6\mathrm{.}5,$ A$6\mathrm{.}7-$A$6\mathrm{.}10)$

a$.$ Create the interface shown in Figure $6-51.$ Display numbers from o through $20$ in the lstPremium control. Display numbers from o through $100$ in the lstConnections control. When the interface appears, the first item in each list box should be selected.

b$.$ The Calculate button's Click event procedure should calculate and display a customer's cable bill. The cable rates are shown in Figure $6-52.$ 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.
