export some .net dlls to use then from C++

We have an SDK made un .NET that provides us with a few DLLs but they can only be used from .NET and not from C++ which is what we need to interface with our own software. We are trying to build an ActiveX in C# to export the functions and everything but we are having problems with functions that use objects as in/out parameters. I know there is a VARIANT type that can be used for that in ActiveX, but I have no clue how to use it. Another chance could be serialize the objects, but there are too many functions and objects and it would mean too much work. I don't know if there is any other way to solve this, such as an automated conversion tool to export .NET dlls as COM interop. I need some help from someone who knows the best way to get around this problem

In general i suggest to use C++/CLI But solution could be another if you have source code of .NET components

Hey! That sounds strange, cause you shouldn't have any problem using .net library (unmanaged dll) in your c++ code. Problems are when you try to do opposites calls, because you need a c++ dll wrapper to use with .NET More

Rather than make an ActiveX control, you may wish to consider using mixed managed/unmanaged assemblies coded in C++. The unmanaged code could be directly consumed by your client applications just like any other library More
