Name The Project Finalexam2 Has A Title Bar With Your Name As The

Develop a simple Windows Forms application named "FinalExam2" with the following specifications:

  • The application should have a title bar displaying your name.
  • Include a text box with a label next to it that reads "Enter an integer:".
  • Provide two buttons labeled "DOUBLE" and "HALF".
  • When the "DOUBLE" button is pressed, the program should display a message box showing twice the number entered in the text box and then clear the text box.
  • When the "HALF" button is pressed, the program should display a message box showing half the number entered in the text box and then clear the text box.
  • Optionally, add features for extra points, such as additional controls or input data validation, with documentation in your code and in a separate text submission.

Prepare the project by zipping the entire folder and submit it along with a text document describing any extra features implemented.

Sample Paper For Above instruction

This project involves creating a simple graphical user interface (GUI) application using Windows Forms, designed to perform basic arithmetic operations—doubling and halving an integer input by the user. The application aims to demonstrate fundamental programming concepts such as event-driven programming, input validation, message dialog boxes, and GUI component placement.

Firstly, the application is designed with a title bar displaying the user’s name. This personalization improves user engagement and demonstrates how to set custom window titles in Windows Forms applications. To facilitate user input, a label reading "Enter an integer:" is positioned next to a text box. The label serves as a prompt, guiding users to input an integer for processing. Ensuring clear and accessible UI elements aligns with usability best practices.

Two buttons, labeled "DOUBLE" and "HALF," are placed prominently within the form. These buttons are wired to event handlers that execute the corresponding functions when clicked. When the "DOUBLE" button is pressed, the application retrieves the value from the text box, validates it to ensure it is an integer, and then calculates twice its value. The result is then displayed in a message box, and the text box is cleared to prepare for subsequent input. Similarly, pressing the "HALF" button results in the application dividing the input by two, displaying the result in a message box, and clearing the input field.

Robust input validation is critical to prevent runtime errors and improve user experience. The program checks if the input is a valid integer, displaying an error message if invalid input (such as non-numeric characters) is detected. This validation enhances the program’s robustness and demonstrates proper error handling in GUI applications.

Additional features, such as input restrictions or input correction mechanisms, could be added for extra points. For example, implementing numeric-only input in the text box, or adding a reset button to clear all fields, could enhance functionality. All extra features must be documented within the code with comments explaining their purpose and implementation. Additionally, a separate text file should describe the implemented features to provide clarity on their functionalities.

The overall development process involves designing the form layout visually in a development environment like Visual Studio, coding the event handlers, and thoroughly testing the application for both usability and stability. Once completed, the project folder should be compressed into a ZIP file for submission, along with the additional documentation detailing any extra features added.
