  1. Programming in Visual Basic 2010 Chapter 4 Novelty Solution

    Programming in Visual Basic 2010 Chapter 4 Novelty Solution

    Regular Price: $15.00

    Special Price: $12.00

    Programming in Visual Basic 2010 Chapter 4 Novelty Solution


    Create a Visual Basic Windows application. Use the following names for the solution, project, and form file, respectively: Novelty Solution, Novelty Project, and Main Form.vb. Save the application in the VB2010\Chap04 folder. Create the interface shown in the figure 4-65. When the user clicks the Calculate Total button, the button's Click event procedure should add the item price to the total of the prices already entered; this amount represents the subtotal owed by the customer. The procedure should display the subtotal on the form. It also should display a 3% sales tax, the shipping charge, and the grand total owed by the customer. The grand total is calculated by adding together the subtotal, the 3% sales tax, and a $15 shipping charge. For example, if the user enters 26.75 as the item price and then clicks the Calculate Total button, the button's Click event procedure should display 26.75 as the subtotal, 0.80 as the sales tax, 15.00 as the shipping charge, and 42.55 as the grand total. If the user subsequently enters 30 as the price and then clicks the Calculate Total button, the button's Click event procedure should display 56.75 as the subtotal, 1.70 as the sales tax, 15.00 as the shipping charge, and 73.45 as the grand total. However, when the subtotal is at least $100, the shipping charge is 0.00. Code the application. Save the solution and then start and test the application. Close the code editor window and then close the solution.

    Visual Basic 2010 How to Program Deitel Exercise 7.15 Telephone-Number Word Generator


    (Telephone-Number Word Generator) Standard telephone keypads contain the digits zero through nine. The numbers two through nine each have three letters associated with them(Fig 7.29). Many people find it difficult to memorize phone numbers, so they use the correspondence between digits and letters to develop seven-letter words that correspond to their phone numbers. For example, a person whose telephone number is 686-2377 might use the correspondence indicated in Fig. 7.29 to develop the seven-letter word "NUMBERS." Every seven-letter word corresponds to exactly one seven-digit telephone number. A restaurant wishing to increase its takeout business could surely do so with the numbers 825-3688 (that is, "TAKEOUT"). Every seven-letter phone number corresponds to many different seven-letter combinations. Unfortunately, most of these represent unrecognizable juxtapositions of letter. It's possible, however, that the owner of a barbershop would be pleased to know that the shop's telephone number, 424-7288, corresponds to "HAIRCUT." A veterinarian with the phone number 738-2273 would be pleased to know that the number corresponds to the letters "PETCARE." An automotive dealership would be pleased to know that the dealership number, 639-2277, corresponds to "NEW CARS."


    Write an application that allows the user to enter a seven-digit number in a TextBox, and displays every possible seven-letter word combination corresponding to that number in a multiple line scrollable TextBox when the user clicks the Generate Words button. There are 2,187 (3 To the seventh power) such combinations. Avoid phone numbers with the digits 0 and 1.

    Professor Arkins want an application that allows him to assign a grade to any number of students. Each student's grade is based on three test scores, with each test worth 100 points. The application should total the test scores and then assign the appropriate grade using the information shown in figure6-38. Open the Grade Calculator Solution( Grade Calculator Solution.sln) file contained in the VB2010\Chap06\Grade Calculator Solution folder. if necessary open the designer window. Code the application. Save the solution and then start and test the application. Close the code Editor window and then close the solution.

    Programming with Microsoft VB 2010 Diane Zak Chapter 6 Exercise 7 Guess a Random Number


    In this exercise, you code an application that allows the user 10 chances to guess a random number generated by the computer. The random number should be an integer from 1 through 50, inclusive. Each time the user makes an incorrect guess,the application should display a message that tells the user either to guess a higher number or to guess a lower number. When the user guesses the random number, the application should display a "congratulations!" message. However,if the user is not able to guess the random number after 10 tries, the application should display the random number in a message. Open the Random Solution (Random Solution.sln) file contained in the vb2010\chap06\Random Solution folder. If necessary, open the designer windows. Code the application. Save the solution and then start and test the application. Close the code editor and then close the solution.

Do not use a MenuStrip control, but use a Save button to save the payments. Add a Show Payments button that displays the Payments table on a separate form in a DataGridView control. A sample main form is shown in Figure 7-17. Catch all exceptions and display a message box if an exception is thrown. Display a confirmation message when a row is added successfully. Hint: Be sure to initialize the BindingSource’s DataSource property with a LINQ Select query when the form is loaded.

    Regular Price: $20.00

    Advanced Visual Basic 2010 Chapter 6 Programming Challenge 9 Weather Station Summary


    The purpose of this programming challenge is to show how events raised by a class can be broadcast to more than one class. Use the Weather Station Events application from Tutorial 6-7 as a starting point for this programming challenge. Create a Summary form, as shown in Figure 6-29, that keeps a running count of each type of event raised by the WeatherStation class. The Summary form’s class contains an event handler for each type of event raised by the WeatherStation class. Just before showing the Summary form, the main form can pass to it a reference to the same WeatherStation object declared at the top of the main form. Use the Show (not ShowDialog) method to display the Summary form. As events appear on the main form, the summary form counts the number of each type of event that has been raised so far.

The property for the monthly salary should ensure that its value remains positive-if an attempt is made to assign a negative value, throw an exception. Write an application that demonstrates class Employee's capabilities. Create two Employee objects and display each object's yearly salary. Then give each Employee a 10% raise and display each Employee's yearly salary again.
