ok , tanks.
it works fine, and I have a question, can we remove the - and + buttons from the jcOpenMapView component and enlarge the image by pinching with your fingers?
and another question,
I tried the jLocation component and it works well with GetGoogleMapsWebUrl and it was not necessary to use any API Key but I could only see a single location on the map, the question is: it is possible to use GetGoogleMapsWebUrl with several locations and show them on the same map, because in the example AppLocationDemo1 if it is possible to do it with several locations at the same time but it is done with the GetGoogleMapUrl function and with GeoPoint2d that do need an API key.
