right, silly question, but how do I access "e.Graphics" outside the scope of this function?

 private void HopfieldRecForm_Paint(object sender, PaintEventArgs e)
            Graphics g = e.Graphics;


A graphics object is sealed. It cannot simply be instantiated. you can create one from an image to use to draw to the image, but as far as painting to a form or control, you are pretty much stuck using Paint events. But that's the extent of their usefulness anyway.
