vb.net cf scribble pad

Hi all
Im trying to make a simple point and draw in one colour only vb.net application for my ppc. But whilst i can achieve this in full blown .net 2 i cant get anything close to work in cf.
Basically ideally im looking to scribble into a picturebox and save the result as a bmp file.
Saving the result shouldnt be a problem, but i cant seem to draw from the stylus input.

All the examples in c# are of no use to me as i dont understand c#. I can understand the basics of it but understand vb a lot more.

Does anyone have a working simple sample they know of or can list the On mouse move code here

Many Thanks Guys

James
