    {

        Graphics g;

        int count;

        Random rand = new Random();

        int rr, gg, bb;

        public Form1()

        {

            InitializeComponent();

        }

        private void Form1_MouseClick(object sender, MouseEventArgs e)

        {

            rr = rand.Next(255);

            gg = rand.Next(255);

            bb = rand.Next(255);

            Pen p = new Pen(Color.FromArgb(rr,gg,bb));

            if (count < 20)

            {

                g.DrawEllipse(p, e.X - 40, e.Y - 40, 100, 100);

                count++;

            }

            else

            {

                MessageBox.Show("No more Circles");

            }

        }

        private void Form1_Load(object sender, EventArgs e)

        {

            g = CreateGraphics();

        }

    }
