LabVIEW
OpenStreetMap GPS track
Good Morning.
I am trying to plot or track a GPS coordinates in a open source map (in this case OpenStreetMap).
Everything goes fine but the map des not refresh to the latest position. Probably I am doing something wrong...
I found several interesting online maps like opensemap but when I try to insert it one error message appear
I think is because is a JavaScript map, do you know how I could integrate in a LabView???
Any help is wellcome!!
PD: I am very new with LabView and I have no idea about JavaScript!!!
Best!
Hi Manu,

I guess that's because of heavy overuse of local variables: use wires instead of locals!
I tried the dot net browser instead of the activx based iwebbrowser2 using the snippet from here
This will also result in a javascript related error - which is du to openstreetmaps.org
in some case, you can even navigate to the openastreetmaps javascript - that threw the error - and have a look on it, if you want to scare yourself e.g.
https://opentopomap.org/leaflet/leaflet.elevation/d3.min.js
Bur surprise... the donet browser can render an interactive(!) googlemaps map ...
I am pretty sure you meant to acquire a licence to use google maps commercially ...
turns out - via trial and error - to refresh the dot net browser control inside the while loop - in terms to render a new url via a labview control and the Navigate Methode - the ResetImeMode must be executed.

You likely will be happier by using WebView2 instead of WebBrowser! What's the difference you may ask?
Well, WebBrowser is the interface to the old Internet Explorer engine. Aside from being terribly insecure to browse our modern internet nowadays, you are also likely to run into all kind of Java Script and other errors rather sooner than later.
WebView2 interfaces to the the Edge engine, a modern and much safer method to go onto the internet.
Internet Explorer is as far as I know only a 32-bit application, so not very surprising that you can not interface to it from 64-bit LabVIEW.

An it turns out: no javascript errors, when navigating via webview2 to

this works for me in ms windows 11 pro 23H2, MS Edge WebView2 Runtime Version 114.0.1823.79 (Offizielles Build) (64-Bit),
Most of this stuff was already installed on that computer e.g. via windows updates.

I also tested on a Windows 10 computer, but with no success which might be due to a different version of Edge, the EDGE WebView2 Runtime or the dot net sdk.
Others had similar issues to e.g. here
