Bing Maps Connector - how to limit requests?

[jernejp]

Hi,

I'm using Bing Maps Connector (https://docs.microsoft.com/en-us/connectors/bingmaps/#get-static-map).

I've created an image, and put

BingMaps.GetMapV2(
    "CanvasLight";
    16;
    Location.Latitude;
    Location.Longitude;
    {
        pushpinLatitude: Location.Latitude;
        pushpinLongitude: Location.Longitude;
        pushpinIconStyle: 37
    }
)

I've now realised that his makes loads of API calls to Bing Maps - for 3 users, we've exceeded 2500 calls in total, as the image keeps refreshing. How would I limit the number of requests to 1? So to make sure that the image is only loaded once, even if the user is moving? 

Thanks!

Hi @jernejp 

A possible workaround could be to retrieve your image when your app starts, and to store the result in a variable. Here's what to add to the OnStart property.

Set(varMap;
    BingMaps.GetMapV2(
        "CanvasLight";
        16;
        Location.Latitude;
        Location.Longitude;
        {
            pushpinLatitude: Location.Latitude;
            pushpinLongitude: Location.Longitude;
            pushpinIconStyle: 37
        }
    )
)

You would then set the image property of your image control to varMap. By doing this, you'll only call Bing Maps when your app starts.

Works like a charm, thanks @timl !

One more question - now it sometimes happens that the image doesn't load.

I'm setting the variable a couple times during the app, and it only starts working after the variable has ben set twice or three times. Any ide why that would happen, and how to make sure it gets set?

Thanks!
