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 Modified Gross Solution. Open the Gross Solution.sln file contained in the Modified Gross Solution folder. Change the names of the two independent Sub procedures to CalcWeekly and CalcTwicePerMonth. Modify the code so that the btnCalc$\_$Click procedure $($rather than the two independent Sub procedures$)$ displays the gross pay in the lblGross control. Save the solution and then start and test the application. $($F$6\mathrm{.}2,$ F$6\mathrm{.}3,$ A$6\mathrm{.}5,$ A$6\mathrm{.}6)$
