2. Create an Orders application as shown in the figure below. Orders Number ordered: Add Subtract Total ordered: Exit a) The interface provides a button for adding the number ordered to the total ordered, and a button for subtracting the number ordered from the total ordered. b) Code the application using a class-level variable. c) Be sure to code the text box's TextChanged and Enter event procedures. d) Test the application. (If you add 7 and 5, and then subtract 2, 1, and 6, and then add 10, 7, 4, and 5, the total ordered will be 29.)

Specifications: Lions, Tigers, and Bears Pet Clinic needs an application that displays basic services. The application should be designed with checkboxes to select the various services (such as office call, vaccination, grooming, etc). As each service is selected, the charge for the service should display in an associated label. (When the checkmark is removed, the amount should be removed). As each selection is made, the charges should be added into the total (a variable… consider scope), and displayed in a Total Due area on the application (currency format). Align all numeric data appropriately. Consider what should happen when the checkmark is removed. Include at least 8 services that your pet clinic performs. Include a Clear and Exit button. The clear should clear all checkboxes, appropriate labels, and the total variable. Use the standard Microsoft naming conventions for all controls. Include appropriate comments in your code. This is for intro to C# Can't use parse. Thank…

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.
For each of the following exercises, you may choose to write a console-based or GUI application, or both. Write a program for The Carefree Resort named ResortPrices that prompts the user to enter the number of days for a resort stay. Then display the price per night and the total price. Nightly rates are $200 for one or two nights; $180 for three or four nights; $160 for five, six, or seven nights; and $145 for eight nights or more.
The below form will represent the main form from which the user will navigate to the other forms. Meaning each button should be linked to the appropriate form. E.g. If button Manage Addresses is clicked the form managed addresses should be displayed. The Exit button should successfully terminate the program. Create a void method for each button and name them as follow: LinkToAddresses (), LinkToCustomers (), LinkToDrivers (), LinkToStatus (), and LinkToFreight (). The methods should be called under the appropriate button. For the exit button create a void method named AppExit () this should terminate the program.
True or False Forms and most controls have a Preferences property that allows you to change the object’s background color.
Assignment #2 Design an application to search in a database table of employee records. Each employee record consists of an ID, first name, last name, job title. The user interface should look similar to the sketch shown below. A text field is used to input the search query. A combo box is used to choose the search criteria (e.g. search by ID, search by first name, search by last name). By choosing any criteria and clicking on the "search" button, the correct results should be shown on the "results" pane.
