Open the Commission Solution (Commission Solution.sln) file contained in the VB2010\Chap08\Commission Solution folder. If necessary, open the designer window. Add a File menu and a Calculate menu to the form. Include an Exit menu item on the File menu. Include two menu items on the Calculate menu: 2% Commission and 5% Commission. Assign shortcut keys to the Calculate menu’s items. When the user clicks the Exit menu item, the application should end. When the user clicks the 2% Commission menu item, the application should calculate and display a 2% commission on the sales entered by the user. When the user clicks the 5% Commission menu item, the application should calculate and display a 5% commission on the sales entered by the user. Enter the appropriate code in each menu item’s Click event procedure. Save the solution and then start and test the application. Close the Code Editor window and then close the solution.
