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 and set the title bar to Assignment #1.

The buttons should be named btnBlue, btnYellow, btnRed, and btnGreen. The captions on the labels should be Blue, Yellow, Red, and Green, respectively. The tab order of the buttons should follow: Blue, Yellow, Red, Green. Create access keys by underlining the first letter in each button caption: ‘B’ in Blue, ‘Y’ in Yellow, ‘R’ in Red, and ‘G’ in Green.

Name the textbox txtVerse and initialize it with the Bible verse from John 3:16. When the form opens, the textbox should have input focus. Set the font of the textbox to Script MT Bold, size 12, with bold styling.

Name the labels lblBackground and lblForeground. Set their text to Background and Foreground, respectively. Use Times New Roman, size 12, bold font for the labels.

When the user clicks the Blue button, change the textbox background to blue (Color.Blue). Clicking the Yellow button should change the background to yellow (Color.Yellow). Clicking the Red button should change the text color within the textbox to red (Color.Red). Similarly, clicking the Green button should change the text color within the textbox to green (Color.Green).

The task involves creating a user-friendly graphical interface using Visual Basic that enables dynamic color customization of a textbox, which displays a meaningful biblical verse. This project emphasizes fundamental GUI component arrangement, control properties, event handling, and manipulating visual elements programmatically.

To begin with, setting up the form frmAssignment_1 with an appropriate visual hierarchy is critical. The form should be clearly labeled with the title Assignment #1 for clarity. The main components include: four buttons for color changes, two labels indicating the purpose of certain controls, and a textbox showing the verse from John 3:16. The tab order, access keys, and initial focus should be carefully assigned to ensure accessibility and ease of use.

The four buttons can be arrayed logically, with the labels positioned adjacent for clear guidance—this supports intuitive navigation and interaction. Using underlined access keys (Alt+B, Alt+Y, Alt+R, Alt+G) enhances keyboard accessibility, crucial for users with different interaction preferences.

Regarding the functional implementation, the primary toggle actions involve changing the background or foreground (text) color of the textbox based on the button clicked:

  • Blue Button: Changes background to blue.
  • Yellow Button: Changes background to yellow.
  • Red Button: Changes text color to red.
  • Green Button: Changes text color to green.

The application must properly handle events associated with each button to modify the textbox's visual properties. When the form loads, the textbox should automatically receive focus, facilitating immediate interaction. The font settings should be consistent with the specified styles to improve readability and aesthetic appeal.

Implementing such an application not only demonstrates proficiency with Visual Basic controls and properties but also highlights core programming concepts such as event-driven programming, control initialization, and property modification at runtime. Through this task, users learn to bridge user interface design considerations with functional programming logic, culminating in an interactive and visually appealing application.
