Starting out with Visual C# (4th Edition)
- 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.arrow_forwardAssume certain facts. Points is the name of an int variable, and TextBox is the name of a TextBox control. Create an if-else statement that converts the Text property of the pointsTextBox control to an int and saves the result in the points variable using one of the TryParse methods. If the conversion fails, a message box will appear with an error message.arrow_forwardWrite an assignment statement that assigns the result of the Val(txtSales.Text) *Val(txtTaxRate.Text) expression to the lblTax control.arrow_forward
