hey everyone
i'm a beginner c# programmer and i've been learning out of a tutorial book
i've been making a pong game but for some reason, the animation for the ball isn't working

could you tell me if there's anything wrong with the code?
(copy, paste into c#)

thx:)

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        int x = 46; //initial x position of ball
        int y = 46; //initial y position of ball
        int dx = 8; //position increment for ball on x axis
        int dy = 5; //position increment for ball on y axis
        Graphics g;
        public Form1()
        {
            InitializeComponent();
            this.Paint +=new PaintEventHandler(Form1_Paint);
        }

        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            g = e.Graphics;
            SolidBrush brush = new SolidBrush(Color.Black);
            g.FillEllipse(brush, x, y, 10, 10);
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            moveBall();
        }

        private void moveBall()
        {
            if ((x + dx < 0) || (x + dx > 300)) dx = -dx;
            if ((y + dy < 0) || (y + dy > 255)) dy = -dy;
            x = x + dx;
            y = y + dy;
            Invalidate();
        }

   }
}

By default the 'Tick' event doesn't fire, you have to call timer1.Start();
