Hmm, also wenn schon, dann bitte mit Quellcode

Nagut, ist ja sowiso nicht viel *g*

Code:

public partial class Form1 : Form
    {
        Pen pen;
        Brush brush;

        public Form1()
        {
            InitializeComponent();

            pen = new Pen(Color.Black, 3);
            brush = new SolidBrush(Color.OrangeRed);
        }

        private PointF PolarToPic(double r, double phi)
        {
            PointF Result = new PointF();
            Result.X = (float)(r * Math.Cos(phi + Math.PI / 2) + pictureBox1.Width / 2d);
            Result.Y = (float)(-r * Math.Sin(phi + Math.PI / 2) + pictureBox1.Height / 2d);
            return Result;
        }

        private void pictureBox1_Paint(object sender, PaintEventArgs e)
        {
            double phi = 0;
            double dphi = Math.PI / (double)Zackenzahl.Value;

            double ri = InnerRadius.Value;
            double ra = OuterRadius.Value;

            PointF[] Points = new PointF[(int)Zackenzahl.Value * 2];

            for (int i = 0; i < Zackenzahl.Value * 2; i = i + 2)
            {
                Points[i] = PolarToPic(ra, phi);
                phi += dphi;
                Points[i + 1] = PolarToPic(ri, phi);
                phi += dphi;
            }
            e.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
            e.Graphics.FillPolygon(brush, Points);
            e.Graphics.DrawPolygon(pen, Points);
        }

        private void ParamChanged(object sender, EventArgs e)
        {
            pictureBox1.Invalidate();
        }

        private void Form1_SizeChanged(object sender, EventArgs e)
        {
            pictureBox1.Invalidate();
        }
    }
