Trouble creating a new addin. EA can't find it

[Oliver Chappell]

Hi Geert or anyone else who can help.

I've developed some really useful code by extending working Addin Demo code in c#. This code works fine. However I'm trying to write a completely separate Addin from scratch and I can't get it working.
I've created a class library using Vis Studio 8 and .net 2.0
I've set the assembly to be COM Visible
I've set it to register for COM interop
I've made it start EA and added EA to the reference path (this all seems to work as it starts EA fine)
I've added my .main entry point to the registry in the Sparxs Addin section (I'm sure this is correct as I had to do this for the working code before it worked).

Once EA is lauched I use Manage Addins and get the error message "Error - Missing" against my new add in.
I've tried to register the dll using regasm dllpath /codebase
I've tried to register with regsvr32 (gives error no entry point)

When I search the registry for my working addin, it has the sparxs entry AND a CLSID as if its an active x object. However my new Addin does not have a CLSID entry.

Does anyone know what step I have missed?

Thanks

Oliver,

There must be an error in either the the registry, or the way it is registered.

- What does your registry key look like?
- Does it work when you build in VS (and have visual studio register it for you)
- Can you post a snippet of your addin class?

Hi Geert, thanks for the swift help!
Below  is the entire code just one short class

Here is the .reg file text
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Sparx Systems\EAAddins\EETestAddin2]
@="EETestAddin2.Main"
Which creates
(default) sz EETestAddin2.Main prefixed with the Ab Symbol
Identical to the other working entries for my other working addins

I can't get it working though visual studio either. I'm not sure how to get Visual studio to register it for me other than through the project setting I mentioned in the previous post. Maybe that's the problem?

using System.Windows.Forms;
using EA;

Oliver,

Is the projectname in VS also EETestAddin2?
I have for all my addin classes the following properties defined.
I'm not entriely sure that is necesarry, but it works this way.

Code: [Select]

namespace EANavigator
{


    [ComVisible(true)]
    [Guid("c72f24fb-cc0a-40c4-b241-5f35f3d11521")]
    [ClassInterface(ClassInterfaceType.AutoDual)]
    public class EANavigatorAddin

This is the guts of my properties file, seems similar.
The project name, namespace and dll all have the same name
EETestAddin2

but it looks as if those lines came from your c# code, mine are not there so I'll try addin them just before my namespace declaration

More thanks

Olly

Which file in the project did you get    
   [ComVisible(true)]
   [Guid("c72f24fb-cc0a-40c4-b241-5f35f3d11521")]
   [ClassInterface(ClassInterfaceType.AutoDual)]
from?

[Geert Bellekens]

In the class definition file, right above the class declaration, so right after the namespace declaration.
