Chapter 1, Problem 5E

In this exercise, you modify the Gross Pay application from this lesson. Use Windows to make a copy of the Gross Pay Solution folder. Rename the copy Modified Gross Pay Solution. Open the Gross Pay Solution (Gross Pay Solution.sln) file contained in the Modified Gross Pay Solution folder. Open the designer and Code Editor windows. Locate the form’s Load event procedure. Change both For…Next statements to Do…Loop statements. Save the solution and then start and test the application. Close the Code Editor window and then close the solution.

If you inadvertently create a Click() method for a control that should not generate a click event, you can successfully eliminate the method by ______________. a. deleting the method code from the Form1.cs file b. eliminating the method from the Events list in the Properties window c. adding the method to the Discard window d. making the method a comment by placing two forward slashes at the start of each line

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 items in a combo box belong to which collection? Items List ListBox Values

When you drag a field object to an existing control in the interface, Visual Basic replaces the existing control with a new control.a. True b. False

Please help with the question on the picture

Input data: Feet: User enters a number for feet   Period: User enters a number for inches Instructions: Create a new project and name it as yourlastname-firstname-Assignment5. Save this project in VB folder you created earlier. Change form’s title to: Your full name – Assignment 5 - Conversion. Form contains four Labels, two TextBoxes, and three Button controls.  Use labels to identify Feet, Inches and Meters. See below Form Layout with Controls for more details. Note: You will use the same control Names shown below. - Input variables: Feet (Single)  - TextBox,    txtFeet Inches (Single)  - TextBox,    txtInches - Output variables:  Meters (Single)   -Label,  lblMeters To convert feet and inches to meters, use this formula: (feet * 12 + inches) * 0.0254. 0.0254 is a constant value to convert English system to Metric. Make sure to declare a Constant for this literal number. You construct a Function for this conversion. It will be placed after End Sub for btnConvert_Click. Start…

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.)

This challenge activity consists of a series of auto-generated, randomized questions allowing unlimited submissions. You must correctly answer a question at each level before proceeding to the next level. The purpose of this first level is to familiarize yourself with how the autograder works. Click the "Start" button to begin the challenge activity. Copy the code provided and paste the code into the code window. The following code reads in a value for variable numCucumbers using cin >> and outputs the value of numCucumbers, followed by " cucumbers" using cout <<. cin >> numCucumbers; cout << numCucumbers << " cucumbers" << endl; #include <iostream>using namespace std; int main() {   int numCucumbers; // Creates an integer variable named numCucumbers    /* Your code goes here */    return 0;}
