Another thing you could consider is to build your own browser control in .net:

Hi Marc,

eon_mobile_geolocationex only works for PS Mobile apps. Here you can find a Community tutorial explaining the howtos:

https://community.appeon.com/index.php/articles-blogs/tutorials-articles/9-powerserver-mobile

For Web apps, you must embed (Google) Maps into a Web Browser control. PS Web does not support yet the new Chromium browser, for the time being you must rely on the legacy MS Web Browser (or a 3rd party COM/ActiveX).

Best,

We are now looking at Leaflet - Leaflet is the leading open-source JavaScript library for mobile-friendly interactive maps. Weighing just about 38 KB of JS, it has all the mapping features most developers ever need. Use it through the Chromium-based WebBrowser control in PB2019 R2

Thanks Michael, will also look at embedding to PB via MS Web Browser Control and finding suitable Map Tile Provider in UK.

I embedded OpenStreetMap via Leaflet.js in 20+ years old large MDI-app in Germany 1½ years ago. Great experience.

Embedded into PB app via MS Web Browser Control because we needed bi-directional data and control flow PB app <=> Web Map App.

Map Tile Providers cost money. So check costs. In Germany we chose OSM over Google due to 1) OSM had railway system overlays with excellent metadata that we really needed. - and - 2) Map Tile Provider was "low price" in comparison.

You can build your own map tile provider servers for OSM - but then you need to run additional servers and replicate changes into your local OSM database. That cost was way much higher than paying a reasonable monthly fee.

You can connect with me via LinkedIn if you what to discuss deeper tech issues or implementation details. I'm happy to share my experiences.

Thanks Kevin, yes I don't think I'll have a problem collecting each drivers GPS coordinates, they will need to login to a mobile_server application on their personal mobile phones (customer has said this is how they want it, no permanent cab devices!) Once they are logged in, I'll have a timer running every 30 seconds to grab their coordinates and update a database with each vehicle in it.

I need to know of a way to display an overlay like you can in this mobile demo https://youtu.be/0nalRw9U7UQ

But I'll need to do that from a computer, be it web server through browser or on a compiled exe

Thanks for the reply, if you can find out that would be great

If I understand you correctly and the end game is to display your "fleet" of vehicles on a map on a desktop device, this is very similar to something I did in ~2005/2006.  You can break down what needs to be done in 2 major tasks.  First, you need to receive and store GPS data from your vehicles.  Second, you need to display this data on a map.  For the first part, you're going to need some sort of GPS device on each vehicle.  We used a GPS unit that sent the data in UDP packets to an ip address where we had a Java app running on EA Server.  The Java app processed the udp packets and loaded the data to the Database.  We then used an ARCGIS Active X to display the vehicles on a map in a PowerBuilder client.  Maybe someone from the PowerServer Web side can comment on if it's possible to process udp packets?  Since this was over 10 years ago, I'd imagine GPS devices are capable of sending the data in different formats now too, so check with the GPS unit providers.  You can probably also send from a phone as well, but I'd imagine you'd want a device permanently mounted on your vehicles instead.  As far as displaying the data on the map, I know the company I worked for has since converted to PowerServer Web, and last I heard it was working very well for them.  I can try to reach out to someone from the company if you'd like.  Just send me a message via LinkedIN.
