MapForums

I posted this on the newsgroup but got no replies so if anyone has
ANY thought i would much appreciate them:

Since installing MP2004 on a machine that only ever had MP2002 on it I have a problem.
(did not replace 2002 but installed in different directory so now have both
versions on machine)

// related info //
I am writing an application that uses mappoint as an ole object using the vb programming tools writing in borland c++ builder
eg. OleContainer1->CreateObject(data->mappointVersion,False);

// the problem //
When i tell it to launch the 2002 version using
"Mappoint.Map.EU.9" as the mappointVersion (as opposed to EU.11 for 2004)
it ALWAYS loads up mappoint 2004 without fail and cant get it to load 2002
unless I open it on its own through the start menu.

Why is this please?
...... it is causing me a LOT of trouble and time

Many thanks
Shaun

When I've created COM objects (via C++), the COM object name for the application is of the form:

"MapPoint.Application.EU.9"

Thanks for that but if i try

MapPoint.Application.EU.9

it is unable to use this and get error message
same for .EU.11

Any other thoughts... anyone?

"MapPoint.Application.NA.11" is the example given in the help that comes with MapPoint.
(and EU for European version).

So I suspect the problem is with the C++ Builder environment.
I've never used it before, but I think you have to 'import' the COM classes somehow??

Strange thing is I'm now having the same problem! MSVC (but WTL rather than MFC).

Creating objects with names like "MapPoint.Application.NA.11" works without error, but "MapPoint.Application.NA.9" loads v11 (ie. 2004).

I think we have a bug here!

Incidentally, I also have EU.9 and that loads okay - but I don't have EU.11 installed.

I'm actually working on code to allow a user to select which version my app calls. I think I'm going to amend my code so it only lets the user select the latest&greatest that is available for each geographic region.

Another strange one, not programmatic this time: If you have 2004 Help open, and then try to open the Help in v2002, it just gives you the 2004 window. Closing 2004, and retrying gives you the correct version.

Thanks.
I'm glad that someone else has a similar problem.
does anyone know where we go from here in
recitfying the problem?
microsoft?

Shaun

are there different ocx files for the two versions
and are both loaded in app

OR is run required program be direct call
c:\program\mp.exe acceptable

crud but rud is my way

>are there different ocx files for the two versions
>and are both loaded in app

Yes. the ocx files are different not sure what you mean about
them being both loaded in app?

OR is run required program be direct call
c:\program\mp.exe acceptable

If you are asking if i can use a commandline style command
to run up mappoint then this unfortunatley is not an option
it needs to be embedded in the application

Thanks. S.

Recap: mp running in app as embedded ole object but will only run 2004
even if tell it to run 2002 when both are installed on same machine.

If i re-install 2002 then it will only run 2002
and then if i re-install 2004 it will only run 2004!!

so what central reference is it changing in the registry!?
why cant i tell it which version to use and it use that version!!!????

Anyone?

I think the big problem is, that the two different OCX with Mappoint 2002 and 2004 are using identical registry keys for their controls !

So it´s no problem to run the two different exe-files, but using the ocx, you can only use the last installed version !

MapControl 9.0 and 11.0 have the same keys. example from my app :

IID_MapPoint2004_IMappointCtrl = '{65DEDD2D-938D-4083-80B5-9491B073B7AE}'
IID_MapPoint2002_IMappointCtrl = '{65DEDD2D-938D-4083-80B5-9491B073B7AE}'

IID_MapPoint2002__MapPointUtilities = '{33A1C7CE-9E37-4A11-8213-0413A20C66BA}'
IID_MapPoint2004__MapPointUtilities = '{33A1C7CE-9E37-4A11-8213-0413A20C66BA}'
