Hi,

In a few hours I'll be needing to do an urgent upgrade of my C# program's use of MP 2004, to 2006.

Can anyone give me the heads up on what functions may have changed? And what may need to be done differently?

Clearly I need to change the directory where it loads
New North American Map.ptt

But I doubt I'll be lucky enough for that to be the extent of it.

Also, are there any tricks to adding a reference to MP 2006 into Visual Studio? Where do I get the files:

Interop.MapPoint.dll
AxInterop.MapPoint.dll

When I do a complete install for 2004, I do not find those files, however they are part of my Visual Studio project, although I can not recall where I got them.

Thanks,
Bob

Hi Bob,

The files are created by VS. You have to add reference to the *.ocx file in the COM tab. The file is in the MP directory. The type library if you need it you find in the microsoft shared folder. However after installation all these should be in the COM tab of VS.

For the rest all is backward compatible. Interesting thing: the Location object has a Latitude and Longitude property.

As Wilfried says, the most interesting change are the Location's Longitude & Latitude properties. There were always (well since 2002) there, but only set if the Location was created with a Longitude and Latitude. In 2006, they are always there - ie. you no longer require Gilles' code for finding the coords.

This was one of the reasons why my latest product (in testing) is for MapPoint 2006 only.

thanks.

I also use Gilles' code for finding the coords
