- Which of the following can be used to clear the text contained in the lblTax control? lblTax = String.Empty lblTax.Text = String.Empty lblTax.ClearText lblTax.Text.ClearThe 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 a lottery game application named Lottery. Generate three random numbers, each between 1 and 4. Allow the user to guess three numbers. Compare each of the users guesses to the three random numbers, and display a message that includes the users guess, the randomly determined three-digit number, and the amount of money the user has won as follows: Â Make certain that your application accommodates repeating digits. For example, if a user guesses 1, 2, and 3, and the randomly generated digits are 1, 1, and 1, do not give the user credit for three correct guesses-just one.
