Yeah, you gotta remember that a picturebox is for displaying and not editing
What you want to do is this

Bitmap myBitmap = new Bitmap(100, 100)
Graphics g = Graphics.FromImage(myBitmap)
/// do stuff with
pictureBox1.Image = myBitmap

Here is an awesome FAQ on the GDI that helped me out tons

What he's saying is you don't want to draw the lines on the picturebox itself.
Rather make an Image and put the image on the pictureBox. You can then use
something like

then you could

myBitmap.Save("C:\\stuff.png"); //or bmp but the defaul is png

I'm sure that You really don't have to!

We have tried to make this news branch deeper... and deeper...
.... but that subject was not so philosophical as we have expected.
