Minimizing a window to the system tray makes your application somewhat cool, isn’t it? This functionality can be really useful when you want to run an application in the background, for example, chat applications, anti-viruses, and programs that monitor the state of your machine.
This article requires you to have basic knowledge of programming Windows Forms in C#.
Now, let’s see what we need to include this functionality in any Windows application. There are a few very simple steps towards achieving this.
Form opened up for you. From the Toolbox, add a NotifyIcon control to your form.Resize event. In this handler, you override the basic functionality of the Resize event to make the form minimize to the system tray and not to the taskbar. This can be done by doing the following in your form’s Resize event handler:WindowState property is set to FormWindowState.Minimized.NotifyIcon object, and show the balloon tip that shows some information.WindowState becomes FormWindowState.Normal, disable the NotifyIcon object by setting its Visible property to false.NotifyIcon object in the taskbar. For this, handle the NotifyIcon’s MouseDoubleClick event. Here, you show the form using the Show() method.Remember to set the notifyIcon1.Icon property to a valid Icon resource object; otherwise, the system tray will not show any icon, and your window will never return to the foreground.
I have added some code below to get things started:
// The NotifyIcon object
private System.Windows.Forms.NotifyIcon notifyIcon1;
this.notifyIcon1.Icon =
((System.Drawing.Icon)(resources.GetObject("notifyIcon1.Icon")));
private void TrayMinimizerForm_Resize(object sender, EventArgs e)
{
notifyIcon1.BalloonTipTitle = "Minimize to Tray App";
notifyIcon1.BalloonTipText = "You have successfully minimized your form.";
if (FormWindowState.Minimized == this.WindowState)
{
notifyIcon1.Visible = true;
notifyIcon1.ShowBalloonTip(500);
this.Hide();
}
else if (FormWindowState.Normal == this.WindowState)
{
notifyIcon1.Visible = false;
}
}
private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
this.Show();
this.WindowState = FormWindowState.Normal;
}
Some window applications need to stay running as long as the computer is on; for example, Microsoft Outlook, Yahoo chat etc., need to run all the time unless they are explicitly terminated. This concept of minimizing windows to the system tray is very helpful when too many open windows crowd up the taskbar.
