working with forms

Whatever happened to programming! this is a start for you, you do the rest.

using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        string marqueeText = "private void button1_Click(object sender, EventArgs e)";
        float posX = 0.0f;
        int pos = 0;
        string marquee = "";
        System.Drawing.Graphics formGraphics = null;
        System.Drawing.Font drawFont = new System.Drawing.Font("Tahoma", 16);
        System.Drawing.SolidBrush drawBrush = new System.Drawing.SolidBrush(System.Drawing.Color.Black);
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {          
            posX = this.Width;
            formGraphics = this.CreateGraphics();
        }

        private void button1_Click(object sender, EventArgs e)
        {
                     
            timer1.Enabled = true;

         }

        private void timer1_Tick(object sender, EventArgs e)
        {
            if (pos != marqueeText.Length)
            {

                marquee += marqueeText[pos];
                DrawString(marquee, posX );
                posX--;
                pos++;
            }
            else
            {
                if (marquee.Length > this.Width + 1)
                    marquee = marquee.Substring(1);
                marquee += "   ------    ";
               pos = 0;
             }
            if (posX == 0.0f)
            {
                pos = 0;

            }

        }
        private void DrawString(string s, float pos)
        {
            
            float x = pos;
            float y = 50.0f;
            formGraphics.Clear(this.BackColor);
            formGraphics.DrawString(s, drawFont, drawBrush, x, y);
            //drawFont.Dispose();
            //drawBrush.Dispose();
            //formGraphics.Dispose();
        }

    }
