I know it has been a long time since anything was added to this discussion, but I can't think of a better place to put this...

I used your "simple drawing" example to solve a problem I had with creating images in a picturebox. The application is working very well and I thank you for that.

Now I would like to save the contents of the picturebox to a disk file. It looks like I should be able to add a line in your Save routine like:

Me.Picturebox1.Image.Save(<path and filename>, System.Drawing.Imaging.ImageFormat.Jpeg)

and call the routine from a button click, but the image comes out blank. Can you tell me what I am missing? How would I save the contents of the picturebox to disk?
