minimize app to system tray

Question

I have a Windows forms app powered by C# and Visual Studio 2010.

How can I minimize my app to system tray (not taskbar), then bring it back when doubled click in the system tray? any idea? also, how can I make some menu in the icon in system tray and when I right click it, it shows a menu like Login, Disconnect, Connect, something like that. Also, are there any methods to show like a baloon popping up from the system tray?

PS: I already added a notifyIcon, but I do not know how to use it.

• C# System Tray Minimize To Tray With NotifyIcon
• Minimize window to system tray

Handle the form’s 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: Check whether the form’s WindowState property is set to FormWindowState.Minimized. If yes, hide your form, enable the NotifyIcon object, and show the balloon tip that shows some information. Once the WindowState becomes FormWindowState.Normal, disable the NotifyIcon object by setting its Visible property to false. Now, you want the window to reappear when you double click on the NotifyIcon object in the taskbar. For this, handle the NotifyIcon’s MouseDoubleClick event. Here, you show the form using the Show() method.

private void frmMain_Resize(object sender, EventArgs e)
{
    if (FormWindowState.Minimized == this.WindowState)
    {
       mynotifyicon.Visible = true;
       mynotifyicon.ShowBalloonTip(500);
       this.Hide();
    }

    else if (FormWindowState.Normal == this.WindowState)
    {
       mynotifyicon.Visible = false;
    }
}
