Matt:

Try this instead of using a MathPictureBox use a regular PictureBox and a
Mathlink .NET IKernelLink

EvaluateToImage is essentially an image so save it to as a new Bitmap and
render that image in a pictur box.

private Bitmap MyImage ;
  MyImage = new Bitmap(ml.EvaluateToImage("Plot[x,{x,0,1}]", 400, 400));
   pictureBox1.Image = (Image) MyImage ;

But when I try to use it from a dotNET program, and set the MathCommand
string I always get a System.Format error, saying that the string is the
wrong format. MathPictureBox uses the EvaluateToGraphics method. When I try
to use this in my code I get the same error, even when I paste the API
example directly into my code.
