Highlights
The video begins by launching Visual Studio 2019 and navigating to the 'Create a new project' option. It highlights that Visual Studio is an environment, not a programming language itself, and demonstrates selecting Visual Basic for a Windows Forms App. Users are advised to name their project meaningfully and be mindful of the save location, especially in shared environments.
The interface is introduced, including the menu, toolbar, Solution Explorer (a collection of files for the application), Properties window, and Toolbox. The importance of pinning the Toolbox for constant access is shown. The central area displays the form where the user interface will be built.
A button is added to the form from the Toolbox. The Properties window is then used to change the button's display text to "Press Here" and its name to a more descriptive 'btnStart', following a naming convention. The concept of changing other properties like background color is also mentioned.
Double-clicking the button opens the code view, revealing the form's backend code. The video explains the 'Public Class Form1' and 'End Class' structure and the 'Private Sub btnStart_Click' procedure, which will execute when the button is clicked. It emphasizes not altering the existing code structure.
The 'MsgBox' command is used to display a series of "Hello World" messages. The video demonstrates Visual Studio's auto-completion (IntelliSense) and real-time feedback, such as auto-capitalization and color coding, to assist in writing correct code. It also illustrates how syntax errors are highlighted.
The application is run by clicking the start button, and the sequence of message boxes triggered by clicking the new button is demonstrated. The video concludes by showing how to stop the running application and, importantly, how to save all project files using the 'Save All' button.
