private Button buttton2; private TextBox textbox1;
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
if (this.buttton2 == null)
{
this.buttton2 = new Button();
this.buttton2.Click += new EventHandler(button2_Click);
}
this.buttton2.Text = "Button2";
this.buttton2.Top = 100;
this.buttton2.Left = 150;
this.Controls.Add(this.buttton2);

if (this.textbox1 == null)
{
this.textbox1 = new TextBox();
}
this.textbox1.Top = 120 + this.buttton2.Height;
this.textbox1.Left = 150;

this.Controls.Add(this.textbox1);
