Visual C# 2010 How to Program Deitel Chapter 9 Exercise 9.4 Solution

9.4 (Duplicate Word Removal) Write a console application that inputs a sentence from the user (assume no punctuation), then determines and displays the non-duplicate words in alphabetical order. Treat uppercase and lowercase letters the same. [Hint: You can use string method Split with no arguments, as in sentence.Split(), to break a sentence into an array of strings containing the individual words. By default, Split uses spaces as delimiters. Use string method ToLower in the select and orderby clauses of your LINQ query to obtain the lowercase version of each word.]

Visual C# 2010 How to Program 4E Deitel Chapter 24 Cash Register Microwave and Phone book Applications

24.9 Create a cash-register application modeled after the one presented in Fig. 24.37. It should alow users to enter a series of prices, then obtain the total. The Delete button should clear the current entry, and the Clear button should reset the application.

24.11 Using WPF, create a GUI that represents a simple microwave, as shown below (you do not have to provide functionality) To create the Start, Clear and numerical Buttons, you’ll need to make use of control templates. To apply a control template automatically for a control type, you can create a style (with a TargetType) that sets the Template property.

24.12 WPF allows two-way data bindings. In a normal data binding, if the data source is updated, the binding’s target will update, but not vice versa. In a two-way binding, if the value is changed in either the binding’s source or its target, the other will automatically updated. To create a two-way binding, set the Mode property to TwoWay at the binding declaration. Create a phone book application modeled after the one shown below. When the user selects a contact from the contacts list, its information should display in a Grid of TextBoxes. As the information is modified, the contacts list should display each change.

Visual Basic 2010 How to Program Deitel Chapter 7 Salary Survey Application

Use a one-dimensional array to solve the following problem:
A company pays its salespeople on a commission basis. The salespeople receive $200 per week, plus 9% of their gross sales for that week. For example, a salesperson who grosses %5,000 in sales in a week receives $200 plus 9% of $5,000, a total of $650.

1. Write an application (using an array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assuming that each salesperson’s salary is truncated to an integer amount):
$200-299, $300-399, $400-499, $500-599, $600-699, $700-799, $800-899, $900-999, and over 999.
2. Allow the user to enter the sales for each employee in a TextBox.
3. The user clicks the calculate Button to calculate the salesperson’s salary.
4. When the user is done entering this information, clicking the Show Totals Button displays how many of the salespeople earned salaries in each of the above ranges.

Microsoft Visual Basic 2010 Shelly Cashman Series Chapter 5 Case Problem 7 Technology Conference Registration

Technology Conference Registration
Based on the case project shown in Figure 5-111, create a requirements document and a UseCase Definition document, and then design a Windows application. Before writing the code, create an event planning document for each event in the program.

It is important that developers update their skills by attending developers conferences. The Dynamic International Management Consorttium (DIMC) runs and manages the ADSE (Active Developers Skill Enhancement) Conference two times per year. To encourage companies to send multiple employees to the conference, the cost per attendee is determined based on the number of attending developers from a given company. The table below specifies cost per attendee.
Number of Conference
Registration per
Company Cost per Attendee
1 $695
2-4 $545
5-8 $480
8 or more $395

DIMS has requested that you develop a Windows application that can determine and display the total cost per company for developers attending the conference. DIMC has a conference policy that states if any member of a company has attended a previous DIMC conference, the company receives a 15% discount from the total cost of its employees who attend. The policy also states that no more than 16 people from a single company can attend the conference. DIMC has asked that you design the program so that the user must enter valid data.
