I'm not gonna slap you, but i gotta tell you, that you're wrong

You can do this the following way:

Data -> Territories/Regions (in German it's "Gebiete" and i don't exactly know, how it is called in the English version but i think it's territories cause the shortcut is Strg+T).
Next you have to choose "create manually" and the type of geographical unit (postal code, township, canton, state or country/region).

This way you can select some regions on the basis of the selected geographical unit.

E.g. i have created a region with 3 countries (Germany, Austria, France), which i can save either as a "MapPoint-Map (*.ptm)" or a Maptemplate (*.ptt)"):


Now i want to be able to read this so created region in my c#-App and check if a specific location (vehicle) is in it's boundaries.

thanks & regards
