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.
[table]
Number of Conference~~Registration per~~Company,Cost per Attendee
1, $695
2-4, $545
5-8, $480

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.
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.

Advanced Visual Basic 2010 Chapter 3 Programming Challenge 6 FirstPlay Sports Rental
Create an application named FirstPlay Sports Rental that keeps track of the inventory for a sports rental store.
Requirements Specification
- The user can input a new rental item and add it to the store inventory.
- The user can select an item’s ID Number from a list and remove the item from the inventory.
- The user can select an item’s ID Number from a list and display the item’s properties.
- When the application starts, it reads an inventory list from a file (text format).
- When the application ends, it writes the inventory list back to the same file.
User Interface Details
Display a single sports rental item in a window, as shown in Figure 3-23. Each item has an ID number; a description; daily, weekly, and monthly rental rates; and the quantity on hand. When the application starts, it reads all item information from a file into a collection (implemented as a Dictionary) and copies the item ID numbers into a combo box on the form. The user can select an ID number from the combo box, and display or remove existing items. The user can also add new items to the collection. When the program ends, it writes the collection to the same file.
Startup Form
The application’s startup form displays inventory items and lets users carry out each of the following actions:
- Input fields for a new rental item, and add that item to the inventory.
- Select an item’s ID Number and remove the item from the inventory.
- Select an item’s ID Number and display the item’s properties.
When the form loads, the combo box should contain a list of all inventory ID Numbers.
Returning to Figure 3-23 for a moment, we see that it shows a new item about to be added to the store inventory. When the Add Current Item button is clicked, the button’s handler creates a new Item object and passes it to the class that handles the store inventory. Figure 3-24 shows an example of searching for an item by ID Number. When the user clicks the Display Item button, the remaining item fields are filled in. When the user clicks the Remove Current Item button, the program confirms the operation with the user, as shown in Figure 3-25. If the answer is yes, the program removes the item identified by the ID Number.
Classes
We suggest that the application define three classes: Item, Inventory, and InventoryFile.
- The Item class encapsulates a single inventory item.
- The Inventory class represents a collection that contains all items and provides methods for adding, finding, and removing items. Internally, it should hold the items in a Dictionary object.
- The InventoryFile class is responsible for reading the inventory data from a text file, and writing all Inventory data back to the file.

Penn Foster Graded Project 03784300 Windows Forms and Applications
OVERVIEW
This project will assess your understanding of accessing files, using data-bound controls, and deploying your application.
Make sure that you follow all directions completely and verify your results before submitting the project. Remember to include all required components in your solution.
YOUR PROJECT
In the graded project for Lesson 4, you added the GroceryItemForm to the GroceryApp project. In this project, you’ll
- Add functionality to save and load saved grocery basket files
- Display the contents of the basket using the data-bound control DataGridView
- Add a form to the project to display grocery items in the basket
- Locate and share your application assembly with your instructor
Note: This project is the last graded project based on this scenario. You’ll be graded on the end-user functionality, so variable names and other code conventions are your choice, but the application must behave as expected.
INSTRUCTIONS
- In Visual Studio, load the GroceryApp project that you completed in Lesson 4.
- Open the GroceryItemForm.vb file.
- Add the options &Save and &L oad to the Application menu above the Exit option. You can add the Save and Exit options to the Application menu underneath Exit and then click and drag them above it.
- Add the OpenFileDialog and SaveFileDialog components to the Windows form.
- In the Click event for the Save option, prompt the user for a file location and store the basket as a text file. Recall that grocery items are stored in the basket variable.
Hint: You could use a CSV file similar to a flat-file database, like the example in Section 2 of Lesson - In the Click event for the Load option, prompt the user for a file location and load the contents of the text file into the basket. Make sure you empty the basket first.
Hint: You could use the Split method in the String class to break each line into individual array items. See the MSDN Library at http://tinyurl.com/3odx56 for more details. - Save your work and test the application.
- Add some items to the basket and save them.
- Then attempt to load them again.
- Click on the View option in the Basket menu to see the basket contents. You will modify how this menu option works in the concluding steps.
- Add a new form to the project named BasketDisplayForm.
- Set the Text property to Basket Contents.
- Set the Size property to 600, 300.
- Add a DataGridView control named viewBasket.
- Set the Dock property of the DataGridView control to Fill.
- In the Load event of the BasketDisplayForm, add the following code to display the basket contents in the DataGridView control:
- viewBasket.DataSource = basket
- Notice how simple it is to perform data-binding with collections.
- Go back to the code view of GroceryItemForm.
- Replace the content of the ViewToolStripMenuItem_Click event handler, so that it loads and displays the BasketDisplayForm modally.
Hint: You don’t have to worry about the basket variable, because the BasketDisplayForm handles data-binding in its Load event.
- Save and run the application. Verify that all controls and menus work correctly. You’ll submit the compiled application for this project.
SUBMISSION GUIDELINES
You’ll submit the GroceryApp.exe file for your project. To find this file, you should go to directory where you saved the GroceryApp project. To open the project directory, right-click on GroceryApp in the Solution Explorer panel and choose the Open Folder in File Explorer option in the context menu.
Go to the bin\Debug folder and copy the GroceryApp.exe file to your desktop or any other temporary location. You should make sure the GroceryApp.exe file executes before submission. You can double-click on it without using Visual Studio for testing.
GRADING CRITERIA
Your project will be graded using the following rubric:
[table]
TOTAL, 100 points
The Save menu option performs the correct behavior, 30 points
The Load menu option performs the correct behavior, 30 points
The View menu option performs the correct behavior, 15 points
The BasketDisplayForm is laid out correctly 15, points
The compiled application is included and runs, 10 points
