NotifyIcon Component Overview (Windows Forms)
The Windows Forms xref:System.Windows.Forms.NotifyIcon component is typically used to display icons for processes that run in the background and do not show a user interface much of the time. An example would be a virus protection program that can be accessed by clicking an icon in the status notification area of the taskbar.
Key Properties of NotifyIcons
Each xref:System.Windows.Forms.NotifyIcon component displays a single icon in the status area. If you have three background processes and wish to display an icon for each, you must add three xref:System.Windows.Forms.NotifyIcon components to the form. The key properties of the xref:System.Windows.Forms.NotifyIcon component are xref:System.Windows.Forms.NotifyIcon.Icon%2A and xref:System.Windows.Forms.NotifyIcon.Visible%2A. The xref:System.Windows.Forms.NotifyIcon.Icon%2A property sets the icon that appears in the status area. In order for the icon to appear, the xref:System.Windows.Forms.NotifyIcon.Visible%2A property must be set to true.
NotifyIcons Options
You can associate balloon tips, shortcut menus, and ToolTips with a xref:System.Windows.Forms.NotifyIcon to assist the user.
You can display balloon tips for a xref:System.Windows.Forms.NotifyIcon by calling the xref:System.Windows.Forms.NotifyIcon.ShowBalloonTip%2A method specifying the time span you wish the balloon tip to display. You can also specify the text, icon and title of the balloon tip with the xref:System.Windows.Forms.NotifyIcon.BalloonTipText%2A, xref:System.Windows.Forms.NotifyIcon.BalloonTipIcon%2A and xref:System.Windows.Forms.NotifyIcon.BalloonTipTitle%2A, respectively. xref:System.Windows.Forms.NotifyIcon components can also have associated ToolTips and shortcut menus.
