I have some VBA code that needs to talk to a running c# application.
For what it’s worth, the c# application runs as a service, and exposes an interface via .net remoting.

I posted a question regarding a specific problem I’m having already (From VB6 to .net via COM and Remoting…What a mess!) but I think I may have my structure all wrong…

So I’m taking a step back – what’s the best way to go about doing this?
One thing that’s worth taking into account is that I want to call into the running application – not just call a precompiled DLL…

    I’ve come up with a solution using my original structure…

    That is, the VBA application calls a COM wrapper application that translates all of the types from .Net to COM safe types. This wrapper then calls the main service using .net remoting.

    The problem I was having was that the common dlls between the wrapper and the service needed to be in the C:\Program Files\Microsoft Office\Office12 folder (along side msaccess.exe).

    While I was using the AssemblyResolve method to provide the dlls at runtime, this wasn’t working…So for now I’ll just have to have the dlls copied to the folder – a far from elegant solution, but at least the communication is working for now.
