    public partial class Form1 : Form
        public Form1()
        public delegate void DelegateDefinition();
        private void button1_Click(object sender, EventArgs e)
            DelegateDefinition delgate = new DelegateDefinition(CreateButton);

            Button button = new Button();
            button.Parent = this;
            button.Location = new Point(10, 10);
