I am just want the program to shrink as an icon and show at the right down cornor of Explorer tool bar.

• Drag a NotifyIcon component to the form.
• Choose an icon in the designer for the NotifyIncon component.
• Handle the resize event of the Form.(When the window state of the form is Minimized, set the NotifyIcon to true)

        public Form1()
        {
            InitializeComponent();
            this.notifyIcon1.Visible = false;
            this.Resize += new EventHandler(Form1_Resize);
        }



        void Form1_Resize(object sender, EventArgs e)
        {
            this.Hide();
            if (this.WindowState == FormWindowState.Minimized)
            {
                this.notifyIcon1.Visible = true;
            }
        }

• Drag a ContextMenuStrip control to the Form, and name it to contextMenuStrip1.
• Select NotifyIcon component, choose ContextMenuStrip property, and set it to contextMenuStrip1.
• Add ToolStripMenuItem to the ContextMenuStrip, and change it's Text to "Open".
• Add click event handler for the ToolStripMenuItem.
• In the Click event handler, invoke the Show method of the Form to show the main form.

First: How to set the contextMenuStrip1 with notifyIcon1->ContextMenuStrip
second : I don't have a ToolStripMenuItem , only ToolStrip
third : How to use the show method.
If you have code, I'm appreciated for that.

• Double click the icon docked in the System tray.
• Right click the icon, and then the context menu item appears, we click "open" to show the main form.
