Hi

I am finding the location on one map and saving it to global variable.
I pass the global variable to another map so I can add a pushpin.
This is falling over as it seems that you have to find the location on each map which is making things very slow.

Has anyone seen this, or know of a workaround?

Thanks.

Trying to pass a Location object from one instance of MapPoint to another isn't something I've tried - but I'm not surprised it doesn't work.

If the position of the Location is important only but not the associated information (eg. address, point of interest); then you could serialise the Location as a Longitude,Latitude coordinate.
If you search the articles section of this website, there's an article showing you how to get the Longitude,Latitude of a Location - its VB but easy to port to C++.

Then you can pass the coordinate as two doubles, and recreate it in the second MapPoint instance. This only transfers the physical position, though, and not address information or Point-of-interest information.
It is, however, quicker than doing a FindAddress or similar!
