Each of the following files in the Chapter.08 folder of your downloadable student files has syntax and/or logical errors. In each case, determine the problem, and fix the program. After you correct the errors, save each file using the same filename preceded with Fixed. For example, DebugEight1.cs will become FixedDebugEight1.cs. a. DebugEight1.cs b. DebugEight2.cs c. DebugEight3.cs d. DebugEight4.cs

In this exercise, you modify the Grade Calculator application from this chapter’s Apply lesson. Use Windows to make a copy of the Grade Solution folder. Rename the copy Grade Solution-Intermediate. Open the Grade Solution.sln file contained in the Grade Solution-Intermediate folder. Open the CourseGrade.vb file. The DetermineGrade method should accept an integer that represents the total number of points that can be earned in the course. (Currently, the total number of points is 200: 100 points per test.) For an A grade, the student must earn at least 90% of the total points. For a B, C, and D grade, the student must earn at least 80%, 70%, and 60%, respectively. If the student earns less than 60% of the total points, the grade is F. Make the appropriate modifications to the DetermineGrade method and then save the solution. Unlock the controls on the form. Add a label control and a text box to the form. Change the label control’s Text property to “&Maximum points:” (without the quotation marks). Change the text box’s name to txtMax. Lock the controls and then reset the tab order. Open the form’s Code Editor window. The txtMax control should accept only numbers and the Backspace key. Code the appropriate procedure. The grade should be cleared when the user makes a change to the contents of the txtMax control. Code the appropriate procedure. Modify the frmMain_Load procedure so that each list box displays numbers from 0 through 200. Locate the btnDisplay_Click procedure. If the txtMax control does not contain a value, display an appropriate message. The maximum number allowed in the txtMax control should be 400; if the control contains a number that is more than 400, display an appropriate message. The statement that calculates the grade should pass the maximum number of points to the studentGrade object’s DetermineGrade method. Make the necessary modifications to the procedure. Save the solution and then start and test the application.

The purpose of this exercise is to demonstrate the importance of testing an application thoroughly. Open the FixIt Solution.sln file contained in the VB2017\Chap04\FixIt Solution folder. The application displays a shipping charge that is based on the total price entered by the user, as shown in Figure 4-64. Start the application and then test it by clicking the Display shipping button. Notice that the Shipping charge box contains $13, which is not correct. Now, test the application using the following total prices: 100, 501, 1500, 500.75, 30, 1000.33, and 2000. Here too, notice that the application does not always display the correct shipping charge. (More specifically, the shipping charge for two of the seven total prices is incorrect.) Open the Code Editor window and correct the errors in the code. Save the solution and then start and test the application.

Create an application class named LetterDemo that instantiates objects of two classes named Letter and CertifiedLetter and that demonstrates all their methods. The classes are used by a company to keep track of letters they mail to clients. The Letter class includes auto-implemented properties for the name of the recipient and the date mailed. Also, include a ToString() method that overrides the Object classs ToString() method and returns a string that contains the name of the class (using CetType and the Letters data field values. Create a child class named CertifiedLetter that includes an auto-implemented property that holds a tracking number for the letter.
