Hi,
I've been working on an order management system for some time, about 1.5 years. It's written in .NET so I use .NET Compact Framework 3.5. All this time I tried different brands and versions of navigation software. In Windows Mobile (both Windows CE and Mobile) I had some problems managing 2 softwares, our application and the navigation software. For a desktop solution it's easy to implement some mapping software to your solution, like MapInfo's ActiveX or a custom control working with Google Maps, Bing Maps, etc...
For any mobile version, I never found a navigation software which can provide a User Control which can be added to your own application, so you won't have to deal with 2 seperate processes.
So has anyone tried or remember a Windows Mobile solution like an ActiveX control or something?
