4. Professor Jones wants an application that calculates and displays a students average score on two tests. Open the Jones Solution (Jones Solution.sln) file contained in the ClearlyVB2012\Chap09\Jones Solution folder. (The image in the picture box was downloaded from the Open Clip Art Library at http://openclipart.org.) Code the Calculate buttons Click event procedure. The procedure should verify that each score is valid. A valid score is one that is greater than or equal to zero. The procedure should display an appropriate message in the lblMessage control when one or more scores are not valid; otherwise, it should calculate and display the average score. Format the average score using the N1 format. Save the solution and then start and test the application. Close the Code Editor window and then close the solution.
