- 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_forwardIn 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.arrow_forwardA Costume shop requests a Computer application that advertizes Costume rentals. This week's Costume rental specials are as follows : Table Costume Price per week Renaissance Fair $40 Stormtrooper $49 Batman / Batgirl $36 Pirate $29 Write an application that allows the user to select any of the five costume rental specials. When the user selects a costume, the corresponding cost and a picture of the costume should be displayed. Clear each prior price and picture when the user selects a different costume. After selecting a costume, the user should be able to book the costume rental and then CLOSE the window. Visual BAsicsarrow_forward

Create an application that allows the user to enter the amount of time that an object has fallen and then displays the distance that the object fell. The application should have a method named FallingDistance. The FallingDistance method should accept an object’s falling time (in seconds) as an argument. The method should return the distance in meters that the object has fallen during that time interval.arrow_forwardCreate an application that lets the user enter his or her weight (in pounds) and height (in inches). The application should display the user’s body mass index (BMI). The BMI is often used to determine whether a person is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula: BMI = weight × 703 ÷ height2arrow_forward

Solar Panel InstallationThe Megawatt solar panel company installs solar panels on home rooftops. The base installation charge of $2,000 includes two panels. The charge for each additional panel is $300. The normal waiting time for installation is two weeks, but customers can pay an express charge of 5% of the total cost to reduce this time. Create an application that collects the required information from the user and calculates the charges for the installation.The user should input the following information: first name, last name, phone, number of panels, deposit amount, and a check box for the express installation option. When the user clicks a button to view the charges, display a group box containing the following information: base installation charge, cost of installing additional panels, total installation cost, deposit amount, and balance due.Error checking should include the following criteria:• The name and phone fields cannot be blank• The number of panels must be an…arrow_forwardThe user enters an integer into a text box and clicks on the Calculate button. The application will sum all of the integers from 1 to the number entered and display the sum in a label. The sum of numbers is the sum of all the numbers from 1 to the ending number. For example, if the user enters 3, the sum of numbers is 1 + 2 + 3 = 6. If the user enters 5, the sum of numbers is 1 + 2 + 3 + 4 + 5 = 15. Your program should work for any integer entered by the user. Use a loop to calculate the sum of numbers. You will need to initialize the variables and assign appropriate values. Get the value for intEndNum from the textbox. After the loop has run, display intSum in the label. Here is one way to code the loop: For intCount = 1 To intEndNum intSum = intSum + intCount Next Calculate Button Click-Event Procedure You may find following these steps helpful: Declare three variables intEndnum Ending number provided by the user intCount…arrow_forward
- The sales manager wants an application that allows him toenter the current bonus rate. The program should display each sales person’s number(1 through 10), total sales amount, and total bonus amount. It also should displaythe total bonus paid to all salespeople. Display the bonus amounts with two decimalplaces. Save and then run the programarrow_forwardWrite a tkinter application that asks the user to create their own pizza. First, they should enter their name. Then, allow them to pick one of three crusts (thin, regular, deep dish), one of three sauces (Regular, BBQ, Alfredo), and any number of 3 toppings (Pepperoni, Olives, Mushroom). They should also pick if they want a small, medium, or large pizza. When the submit button is clicked, calculate the total cost ($10 base price, $0.50 for each topping, and $1.50 for each increase in size larger than small). Once the total is calculated, display a messagebox that thanks the user (by name) for their order and prints out the total cost.arrow_forwardThe Megawatt Solar Panel Company installs solar panels on home rooftops.
