MapForums

Hi,
I'm new to MapPoint and quite new to VB.Net.

I am trying to create a very simple test application. I have added the reference to Microsoft MapPoint 11.0 Object Library and have the following vb.net code

Dim app As MapPoint.Application
app = New MapPoint.Application()
Dim map As MapPoint.Map = app.ActiveMap


I get a runtime error (see below) when the program gets to the second line of code. I have searched Google for hours now trying to find a solution and have had no luck at all. Does anyone have any ideas?


Thanks.


This is the error message displayed:-

Retrieving the COM class factory for component with CLSID {15A40122-24D2-4FDB-8155-5F65FCE7017F} failed due to the following error: 80040154




This is the detailed error:-

System.Runtime.InteropServices.COMException was unhandled
ErrorCode=-2147221164

Hi,

I have no idea at the moment, but a simple experiment can probably show if all installations are OK. Just create a new winform application, drop a mapppoint activeX control on your main form and see if it load.

if it run OK, and you can open a map then we are at least sure of search path, installation, etc.

Hi,
I created the ActiveX control on the form and ran it and it did nothing.
So I added this code:-

AxMappointControl1.NewMap(MapPoint.GeoMapRegion.ge oMapEurope)


And I get this error:-

MapPoint Europe can't run because it is not registered on your system, or it can't be found. Install MapPoint Europe and try again.

MapPoint is installed and it does seem to run ok.
Should I try a reinstall?

Note: MapPoint is not installed on Drive C:
Due to space limitations I installed it on a spare harddrive U:
Would that cause problems?

Hi,

Could be that different drive is an untested situation.

A simple test is maybe to use OpenMap and give the rith path with it including the drive. Like this (with exact your path of course):
If that helps, I suggest to search in registry for MP or MapPoint or .ptm and related things to see if drive letters are associated.

Hi Wilfried,
I gave that a try and it gave an error saying the file was not a MapPoint file.
I am going to uninstall and re-install to drive C after some space cleaning.

I will post to say whether it makes any difference.

Thank You.

Re-Install to Drive C made no difference.

Any suggestions.

The only thing I can think of is that I installed VS 2005 first and then MapPoint. Would that make any difference?

Hi,

Then there is something else wrong. What if you run mappoint.exe and open the same file with it ?

If I run MapPoint and open the template file it functions just as expected with no errors.

I have re-installed Visual Studio 2005 and it made no difference. I have re-installed the .Net Framework (this was forced after re-installing Visual Studio). I have tried using Visual Studio 2003 which gives me this error:-


An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in MapPointTest.exe

Additional information: COM object with CLSID {15A40122-24D2-4FDB-8155-5F65FCE7017F} is either not valid or not registered


I'm pretty much out of ideas.

Hi,

I'm pretty mutch also out of ideas. Can you try to register the component manually. I think it is with /RegServer command line argument.

I have also tried that with MapPoint.exe /RegServer

It made no difference.
