How do i draw a smooth linie [modified]

[MarkPhB]

i want to create a shape Control like that you got here. But his Control can t draw antialiased linies =/ How can i draw smooth linies ?

[Mark Churchill]

If I recall theres some settings on the Graphics object that can help you out. Anti-aliasing is more of a quality setting on the Graphics object, than specifically asking for the thing you are drawing to be smoothed.

Yea i use this already but it looks not really Antialiased =/ the edges of a pie, for example, looks fuzzy but not smoothed I have a Custom Control wich inherits from the Control class and my paint code looks like this

protected override void OnPaint( PaintEventArgs e ) {
    base.OnPaint( e );

    if( ( this.Width <= 0 ) || ( this.Height <= 0 ) ) return;

    e.Graphics.SmoothingMode = SmoothingMode.AntiAlias;

    GraphicsPath path = createGraphicPath( Shapes.Pie);

    this.Region = new Region( path );

    Pen pen = new Pen( new SolidBrush( borderColor_ ), borderWidth_ );
    pen.DashStyle = borderStyle_;

    e.Graphics.DrawPath( pen, path );

    path.Dispose();
    pen.Dispose();
}
