C# Basics and Working with Forms

C# Basics

• C# code can modify the background color of a form by using this.BackColor=System.Drawing.Color.Green;
• Background color can be changed with predefined colors like "Green", "Blue", "Red"
• The System.Drawing namespace is used for working with graphics and colors in C#
• The using System; statement imports the necessary namespace for working with the console
• Console.WriteLine() is a useful function for displaying output in the console
• In a C# application, a button can be added to a form using the Button control on the Toolbox bar in the Designer
• The Text property of a button can be modified to display text on the button

Working with Forms in C#

• Form1 is a class representing the main window of the application
• partial keyword allows code to be split into multiple files.
• The InitializeComponent() method is called to create the form.
• The System.Windows.Forms namespace is used for working with the Windows Forms framework using the using statement
• In a C# application, you can add a TextBox control from the Toolbox bar to a form to create a text input field.
• The Form1.Designer.cs partial class holds information on the user interface which is generated in the Visual Studio designer
• The Properties window provides access to the properties of the selected component to configure its behavior and appearance

C# and System.Drawing

• Color.FromArgb is a function that helps create different colors by specifying RGB values.
• The Scroll event of a TrackBar control fires when the slider bar's position is changed.
• The Size property of a PictureBox control can be adjusted to change the dimensions of the picture displayed.

Additional Controls

• PictureBox, TrackBar, ProgressBar are controls in C# forms
• Timer controls can trigger events at regular intervals.
• Interval property specifies the time in milliseconds between ticks of the Timer control.
• ToLongTimeString() is a method used to format a DateTime object into a long time string in C#.
• MaskedTextBox provides restricted text input and allows you to specify a mask for input values.
• DateTimePicker enables users to choose a specific date and time from a calendar dropdown
• NotifyIcon is a system tray control that allows for providing notifications to the user.
• ToolTipIcon provides a visual icon to be displayed with notifications.
• ContextMenuStrip can be attached to a NotifyIcon control to provide additional actions for the tray notification.
• The Icon property of a NotifyIcon control can be used to display an icon in the system tray.
• ShowBalloonTip method shows a pop-up notification with a custom message.
• this.Icon refers to the icon of the current Form.

Form Control Events

• Events in C# allow reacting to user interactions with the form, like clicking buttons or changing the values of sliders.
• An event listener is a function that gets executed when a specific event occurs.
• The Click event of a button is triggered when the button is clicked.
• In C# code, this.Close() method is used to close the current form.
• The Form1 class inherits from the Form class, which represents a window in a Windows application.
• You can call Console.Beep() to make the computer play a sound.
• The ScrollEventArgs object provides information about the scroll event, such as the new position of the scroll bar.

This quiz covers the fundamentals of C# programming, focusing on manipulating form properties and using graphical controls. Learn about changing background colors, handling buttons, and utilizing the System.Drawing and System.Windows.Forms namespaces effectively.
