VB dll Project Entry Point?

Hi All,I am creating a fairly simple Addon for FSX using VS2005.Intitially, I've tested the addon running as an executable but I also want to test with addon running as a dll and have hit a brick wall with entry points and definition files.Am I right in thinking I cannot create a dll entry point for a dll project written in VB .NET?If I can, I'd appreciate any advice.Also, does anyone know of any progress towards digital signing for freeware addons? I understand there was some discussion at the end of last year aimed at reducing the costs for freeware authors but I can't find any further information.Thanks for your helpGlynn
