	public class Form1: Form {
		Button button1;
		private NotifyIcon notifyIcon1;
		private ContextMenu contextMenu1;
		private MenuItem menuItem1;
		private IContainer components;
		public Form1() {
			this.Text = "test";

			this.BackColor = Color.Red;
			this.Size = new Size(100, 100);
			this.Location = new Point(1000, 100);
			button1 = new Button();
			button1.Location = new Point(20, 20);
			button1.Text = "test";

			button1.Click += new EventHandler(button1_Click);
			this.Controls.Add(button1);
			this.Shown += new System.EventHandler(this.Form1_Shown);
