I am having a problem moving a MapPoint solution from development to server. I am using MapPoint 2004 installed on my development workstation and VisualStudio.NET (framework 1.0).

In my project I am referencing the MapPoint 11.0 Object Library (North America) type library 8.2 and using the Application.OpenMap() to open an existing MapPoint map.

Everything works great on my workstation, but when I compile the code and move the application to a server (Also with MapPoint 2004 installed) I receive the following error:
-----------------
Exception: System.InvalidCastException
Message: QueryInterface for interface MapPoint._Application failed.
Source: MapPoint
at MapPoint.ApplicationClass.OpenMap(String FileName, Boolean AddToRecentFiles)
at VBMap.Map.Output()
------------------

Can someone give me some suggestions? I have tried replacing the MapPoint 2004 object library reference with the COM dll (extracted from the tlb using the framework tblimp util as seen here: http://support.microsoft.com/default...EN-US;302898#1
) to no avail.

Thank you.

Hi,

OpenMap() works over a network without any problem. Is the path containting valid path? like: '\\machine\c\whatever\etc' ??

Thank you for your help, Wilfried. It is greatly appreciated.

The mappoint .ptm project path is relative to the application path and there is no server-to-server communiction (it all runs on one box) so i am not using a fully qualified path. i am just doing a simple open (I thought).

My compiled .exe resides at
c:\program files\visualoas\myapp.exe
My mapPoint projects reside at
c:\program files\visualoas\mappointprojects\Aproject.ptm.

myapp.exe does something like this:
Dim m_objApp As New MapPoint.Application()
Dim m_objMap As MapPoint.Map

m_objMap = m_objApp.OpenMap("MapPointProjects\Aproject.ptm", false)

Like i said, the code works when running on my dev workstation, that's why i am confused. I can post my VB Class doe that does all the object stuff if you think it will help.

Thanks again.

Hi,

You can also use:

Code:

            MP.NewMap(GeoMapRegion.geoMapEurope);

whitch is 6he default setting and notht path depenefive.

This actually ended up being a server registry/pointer problem. I compared the file systems of the two machines and they were identical. However, a removal and reinstall of MapPoint fixed whatever registry or pointer problem it was having. Kind of strange considering the MapPoint applicatin itself ran fine and was able to open and create maps - I just couldn't use the object library to do it from code.

Thanks.
