Title: Generate C++ Addin
Post by: donk15121984 on October 06, 2006, 01:03:46 am

Hi @ all,
I have a problem when creating an C++ Addin. I have no idea to start. I need an addin with an easy menu. Could you give me a short expression how to create an addin in Visual Studio C++. My problem is that a can't register for COM interop and that my Regkey could not find.

I don't understand why you need to register for COM interop, you would usually only do this for a .NET component.

I'm not aware of any C++ example add ins on the sparx website, strange perhaps given EA is written in C++. I would assume the technique would be to

a) Use the #import directive to import the EA.tlb in the C:\Program Files\Sparx Systems\EA directory.
b) Create a normal ATL object and define appropriate methods such as String EA_Connect(EA.Repository repository).
c) Create your registry key using the same .reg file which ships with the other add in samples, using the full prog id of your component.

We do not have any examples of a C++ Add-In on the Sparx website, but there was one posted to the EA User Group website some time ago by 'Paul Ourada':

I haven't had a proper look at it myself, but I believe this follows along a similar track as Matt said in the previous post.
Please note however, if you are using Managed (.NET) C++ then the configuration may be a bit different, such as needing to have a reference to Interop.EA.dll and not EA.tlb.
