Question
Chapter 9, Problem 4E
Program Plan Intro
Form design:
- Open Microsoft Visual Studio.
- Select Visual Basic and click Windows Application.
- Name the project as “Potter Project”.
- Store the file in desired location.
- The created project is now displayed with a form in the name of Form1.
- Rename the Form1 as “Main Form” and add the necessary components.
- In property window, change the Form name and add changes for Form elements properties.
- Click the File menu->Save All.
View of the form design in the IDE:
The form control properties in the properties window are as follows:
| Object | Property | Setting |
| Form1 | Text | Potter Jr High |
| lstGrades | Items | Grade characters |
| lstNames | Items | (Empty) |
| lblNumber | Text | (Empty) |
| btnDisplay | Text | Display |
| btnExit | Text | Exit |
- Add the list box control to select the grade.
- Add a list box control and label control to display the students name and number of students.
- Add two button controls to display the result and exit the program respectively.

Additional resources in this week’s learning module will provide further perspectives on the impact of wind energy on different stakeholders. Students should refer to the syllabus for specific guidelines regarding length, format, and content requirements. Reflection Questions to Consider: What are the key institutional challenges in implementing offshore wind energy in the North Sea? How do formal and informal social rules shape the use of this shared space? What conflicts arise between different stakeholders (e.g., fishermen, naval transport, military, and wind energy developers)? How can policymakers balance economic, environmental, and social considerations when allocating space for wind energy?…arrow_forward
- Alphabetic Telephone Number TranslatorMany companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663.arrow_forwardI would like help to resolve the following casearrow_forward7.
