Programming Assignment 1 Instructionsadapted Fromintroduction To Progr

Create a Visual Basic form that allows the user to press buttons to change the background and foreground colors of a textbox. The form should include 4 buttons, 2 labels, and 1 textbox. Name the form frmAssignment_1 with the title "Assignment #1" in its title bar.

Set up four buttons with the following properties:

- Name: btnBlue, btnYellow, btnRed, btnGreen

- Captions: Blue, Yellow, Red, Green

- Access Keys: B (Blue), Y (Yellow), R (Red), G (Green), with the underline under the respective character.

- Tab Order: Blue, Yellow, Red, Green

Create two labels with the properties:

- Name: lblBackground, lblForeground

- Text: Background, Foreground

- Font: Times New Roman, 12pt, Bold

Add a textbox named txtVerse containing the Bible verse John 3:16, and set the focus to this textbox when the form opens. The font of the textbox should be Script MT Bold, 12pt, Bold.

When the user clicks the Blue button, the background color of txtVerse should change to Color.Blue. When the Yellow button is clicked, the background should change to Color.Yellow. When the Red button is clicked, the text color of txtVerse should change to Color.Red. When the Green button is clicked, the text color of txtVerse should change to Color.Green.

In modern graphical user interface design, providing users with intuitive controls to modify interface elements enhances usability and accessibility. This assignment serves as an introduction to event-driven programming using Visual Basic, emphasizing the manipulation of control properties through user interactions. Specifically, it focuses on changing the background and foreground colors of a textbox using buttons, an essential concept in GUI programming.

The form, named frmAssignment_1, acts as a container for controls that facilitate user interaction. The four buttons, named btnBlue, btnYellow, btnRed, and btnGreen, are configured with appropriate captions and access keys, allowing keyboard navigation and operation, which enhances accessibility. The labels, lblBackground and lblForeground, provide descriptive text for the interface, styled with a classic font for clarity.

The core functionality revolves around event handlers associated with each button. When a user clicks the "Blue" button, the background color of the textbox (txtVerse) changes to blue, illustrating how control properties can be dynamically altered at runtime. Similarly, clicking the "Yellow" button changes the background to yellow. The "Red" and "Green" buttons modify the text color, demonstrating control property manipulation.

Initializing the form with the specific Bible verse John 3:16 not only provides context but also emphasizes the importance of setting initial properties, such as font and focus, to improve user experience. Using the Script MT Bold font ensures stylistic consistency, and setting the focus to the textbox upon startup allows immediate interaction.

This assignment introduces key programming concepts: control naming conventions, event handling, property modification, accessibility features, and initial control setup. It lays foundational skills for developing interactive Windows Forms applications that respond to user inputs, fostering better practices in software development.
