In this exercise, you modify the Gross Pay application from this chapter's Focus lesson. Use Windows to make a copy of the Gross Solution folder. Rename the copy Gross Solution$-$Functions. Open the Gross Solution.sln file contained in the Gross Solution$-$Functions folder. Change the two independent Sub procedures to functions named GetWeekly and GetTwicePerMonth. Modify the code so that the btnCalc$\_$Click procedure $($rather than the two functions$)$ displays the gross pay in the lblGross control. Save the solution and then start and test the application. $($F$6\mathrm{.}2,$ F$6\mathrm{.}3,$ F$6\mathrm{.}5,$ A$6\mathrm{.}5,$ A$6\mathrm{.}7)$
