DLL's, Interop and App.Config.

I need to read the value of an app.config file from a .NET DLL through Interop from a VB6 app.
The DLL is part of a larger winform app - but I am just using the DLL for the Interop.
But of course you cannot read an app.config from just a DLL - it needs to be in an app with an exe file associated. I get nothing when I try and read the app.config using the usual .NET routines in this COM Interop situation.
So, how can this be done in real life?
Can I send my setting value through the interop into DLL for the .NET DLL to store this where it can be read as if the DLL had an app.config?
NOTE: I have tried reading froam the app directory but in Interop this appears to be the VB6 runtime directory.

Have you tried using the ConfigurationManager.OpenExeConfiguration method, specifying the path to the config file?
