In this exercise, you will complete the Moonbucks application that you created in Exercise 2 in Chapter 2. Use Windows to copy the Moonbucks Solution folder from the VB2017\Chap02 folder to the VB2017\Chap03 folder. Open the Moonbucks Solution.sln file contained in the VB2017\Chap03\Moonbucks Solution folder. The applications Planning Chart is shown in Figure 3-36. Use either a flowchart or pseudocode to plan the btnCalc_Click procedure. Enter the three Option statements in the Code Editor window. Code the procedure using variables and a named constant. Display the calculated amounts with a comma (if necessary) and two decimal places. Save the solution and then start and test the application. (If the current sales amount is 2300.75, the increase and projected sales amounts are 230.08 and 2,530.83, respectively.) Now professionalize your interface by coding the text boxs TextChanged and Enter event procedures. Save the solution and then start and test the application.
