Hi friends,

I'm developing a program with MP 2009 North America version. But customer has the 2006 version. I'm developing with the object model (type library, so not the ActiveX component).

Question is will all work backwards compatible or do I have to do the development with the older type library linked? (but for the 2006 version I only have the European version or does it not matter?).

Yes you should develop against the 2006 version, although the API itself hasn't changed the object versions have.

Europe / North America shouldn't matter but make sure you don't specify the region in the object versions (this is optional, but if you explicitly specify "EU" then it won't work).

There are a few minor differences - valid road speed parameters. Also geocoding lookup -"Other City" doesn't really make sense in the US, for example.

Ok thanks Richard

Sorry if these questions sound a bit stupid....

I've developed a program on 2006. However, customers are now starting to install 2009 and 2010.

It's using the ActiveX control, and when customers use 2009 or 2010, it doesn't work.

Am I reading this right that if I use the "Dim MPApp As New MapPoint.Application" syntax and deal with MapPoint in this way, then it will work regardless of which version is actually installed on the end user's computer?

Hopefully someone can clarify!

The other option I had was to create a "server" as a seperate program, which has an ActiveX control. This then interfaces to my program, passing the maps as graphics and the program passes the commands to this server. Then I just need a server for each version of MP installed.

Again, apologies if these are stupid questions.

My understanding of the CreateObject/GetObject syntax is that it looks in the registry to instantiate the MapPoint application via the Component Object Model (COM) and will seek out the currently registered version.

There does seem to be a problem when both the NA and EU versions are installed for 2006 _and_ 2009 - that is, you have to use "path/MapPoint.exe"/regserver.

Not sure about your other approach - sounds somewhat complicated.

Hi,

As Michael aready mentioned, if you use the object model all versions will work.

If you use the ActiveX control then it should be backwards compatible. For example I have compiled applications with MP 2006, and I can run them with 2009 installed. I don't have 2010 yet.

It will not necessary work the way around. eg if you compile with the registered version of MP2009 activeX then your application will not necessary work with MP2006.
