  1. Advanced Visual Basic 2010 Chapter 5 Programming Challenge 5 Training Workshops

    Advanced Visual Basic 2010 Chapter 5 Programming Challenge 5 Training Workshops

    Regular Price: $25.00

    Special Price: $20.00

    Advanced Visual Basic 2010 Chapter 5 Programming Challenge 5 Training Workshops


    Use the Programming Challenge 3 from Chapter 1 as a starting point for this challenge.
    This version will be a 3-tier application.
    1. Add an ID property to the Workshop class.
    2. Create a database to replace the data file that was used for input in Chapter 1. In it, create a database table named Workshops that contains the workshop ID, category ID, number of days, cost of the workshop, and workshop title. Also in the database, create a Categories table that contains category ID and category description columns.
    3. Create a DataSet containing table adapters based on the two database tables. In addition, create a TableAdapter that joins the two tables and contains the workshop ID, workshop category name, number of days, cost, and workshop description.
    4. The Workshop class represents the middle tier. In this class, declare an instance of the TableAdapter class so you can call the TableAdapter methods. Provide properties and methods in the Workshop class that are called by your MainForm and DetailsForm classes.
    5. Display the list of workshops in a DataGridView control, as shown in Figure 5-32. When the user selects a workshop in the grid, display the Workshop Details form, as shown in Figure 5-33. The combo box is filled from the Categories TableAdapter. The user must be able to modify a workshop in this window and save his or her changes. When the details form closes, the grid must be refreshed, so the user can see the changes he or she made.

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

    Regular Price: $20.00

    Special Price: $15.00

    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.

    (Employee Class) Create a class called Employee that includes three pieces of information as instance variables-a first name (type String), a last name (type String) and a monthly salary (type Integer). Your class should have a constructor that initializes the three instance variables. Provide a property for each instance variable. 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.

    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.

    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.

    BMIS 209 Programming Assignment 7 Account hierarchy

    Regular Price: $15.00

    BMIS 209 Programming Assignment 7 Account hierarchy


    Based on the program you created for Assignment 5, modify your code to perform the following steps.


    In Assignment 5, you created an Account hierarchy with a base class (Account) and two derived classes (SavingsAccount and CheckingAccount). Three of the mutator methods in this assignment validated user input: setBalance, setInterestRate, and setFeeCharged. In all of these methods, you were instructed to set the respective variables equal to zero if the user passed in a negative amount. In this assignment, you will modify your code such that if the user passes in a negative amount, an exception will be thrown that alerts the user that a negative amount has been entered. The program should catch the exception and display the error message to the user. Once an error (negative amount) has occurred, the program should inform the user that negative numbers are not permitted. It should then redisplay the menu. If an exception has not occurred, and a checking or savings object has been successfully created, the program should print the information for that object.


    [Hint: You will need to create an exception class – call it NegativeNumberException – that takes a string as an argument to its constructor that represents the error. The string should be "Invalid Entry – Negative numbers are not permitted."]


    Modify your Main() method such that instead of hardcoding the SavingsAccount and CheckingAccount information, you prompt the user to enter the needed information. Generate a menu like the one below and loop until the user enters "Q" to quit the application.


    Based on the 18 steps required for Assignment 5, you only need to implement steps 1 and 2 and instantiate their creation based on the user's menu selections. You may remove steps 3 through 18. This assignment is only intended to demonstrate your ability to handle exceptions.

  10. POS 409 Week 4 Inheritance C# Program

    POS 409 Week 4 Inheritance C# Program

    Regular Price: $20.00

    Special Price: $15.00

    POS 409 Week 4 Inheritance C# Program


    Create a base class that will include the properties of some type of data related to the company you work for or a favorite hobby. For example, I work for a healthcare provider, so my base class might be "Medical Facility". Include at least five properties. Be creative with your classes -employee type classes are not acceptable. In addition, include data of a variety of types in your classes.


    Add a second class (derived class) that inherits from the base class and describes a subgroup of the base class. In my example, a derived class might be "Clinic". Define at least three properties that are specific to this derived class.


    Design, implement, test, and debug a C# program that asks the user to enter properties for the classes you have defined on a single form. Enhance the user interface by including two groupboxes. In the first groupbox, place the controls for the base class. In the second groupbox, place the controls for the derived class. The entries will include fields for the properties of the base class, as well as the derived class. Add a second form to your project that will display a cumulative list of all the data that the user has entered. A cumulative list means that if the user enters data for 10 clinics (in my example), then 10 clinics will be viewed on the second form. Please note that it is not acceptable to write the data gathered to a database for presentation of the data on the second form. Databases are a topic for week 5, not this week. Also note that it is not acceptable to use text files as a means of transferring data from one form to the other. Text files were used for the last two assignments, so it is time to try some new techniques. The type of application to be developed is a Windows Forms application.


    As with prior weeks, remember to utilize the concepts described in the weekly reading to complete the project.


    Include identifying information in the form of block comments at the top of each class in the project (programmer name, date, program description). Include adequate comments throughout the program, utilize meaningful names for controls, variables, fields, and forms. Include white space for readability purposes in the code. The focus of the project is on learning the C#.Net syntax. However, ensure the form is simple and easy to understand for the user. Refer to the Individual Assignment grading form to view grading criteria.


    Zip the files of the project together and submit the zipped file.
