GPS/MapPoint VB Source Code
I've made a simple GPS/MapPoint application for anyone who wants to write their own VB app to capture and process GPS data.
EDIT: A version that doesn't need a MapPoint control is also available
It's not intended as a app to actually use in your CarPC but it is intended to help anyone who wants to get their app started quickly without having to work out how to do the GPS capture from scratch.
The code is licensed under the BSD License so you're not oblicated to release the source code of anything you make using my code. There may also be bugs in the code, if you find any feel free to tell me so I can update the code. I don't guarantee it to be perfect, but it should help get you started.
It's fully commented so you shouldn't have any problems working out what does what.
It is availble for download from http://www.stevieg.org/opensource
If you need an app to simulate GPS data while you are testing I can recommend 'GPSGate' - http://franson.biz/gpsgate/ which is $29 and also allows you to split your actual GPS as well if you want to make an app that runs alongside your usual Navigation software.
Thanks to James Warner for letting me look at his GPS/MapPoint source code to get the idea of how it's approached, however this was coded on a clean machine without looking at his source code with my own research and approach, none of his code is in this whatsoever.
Hope this helps someone
