Please post questions in the questions forum. Which library are you using?

I used Geocoder.
my code :

Public GeoC As Geocoder
...
Dim str(2) As Address
str = GeoC.GetFromLocation(Lat,Lon,2)

GetFromLocation is very slow method and i tried to move the code "GetFromLocation" in timer or service, but the sistem during the work this method is in foreground.
is there a way to read the position without blocking?


I have not understand how to move this post.

Seems like this library is doing the network call in the main thread. This is not good.

You can use the Threading library to call this method with a background thread or use a different solution.

I updated Geocoder last December so that it runs in a background thread and raises an event when the job is done: Geocoder library.

The code that Vincenzo posted is not using the latest version of Geocoder - or he's using the old 'main thread' syntax with the new version.

@Vincenzo
Get the latest version of Geocoder and the run the examples - the examples show how to use the new background thread syntax.

The most recent version of the geocoder library (by warwound) (2.01) makes the network call in its own thread and fires a GeocodeDone event when the geocoding is finished.

@Vincenzo: Update your geocoder library to the latest version and change your code to use the GeocodeDone event.

OK,
thanks for information. I used the V1.0 maybe it was a little old . I've updated the library V2.01 and managed as the example, the system seems to be much improved. All OK.
