Autocad 2006, objectarx and Visual C++ express

Hi everyone,

So far, I am developing for autocad 2012 using objectarx and VC++ Express edition without problem.

Now I need to develop for Autocad 2006 with ObjectArx, using VC Express edition. I don't need MFC.

I couldn't make it work with VC express 2008, I am currently giving it a try with VC express 2005.

So far:

- I installed and updated to SP1 VC Express 2005

- I installed ObjectArx 2006

- I Installed Objectarx wizard 2009: I couldn't install the 2006 one: had the error described in This topic

It works thanks to this post: http://through-the-interface.typepad.com/through_the_interface/2006/07/getting_the_obj.html

I create a basic objectarx project in VC (no MFC, no COM), set the correct paths (include and lib in my project settings), and when I try to compile, I get the error C4430, same as here

I can't find any solution despite my searches, is it really possible to develop objectarx for autocad 2006 with an express VS?
