Calling .net object from 16-bit application

[Guest]

Hello,

I have a 16-bit application which has to make COM calls to a .NET object. Previoulsy, when i was using VB6.0, the 16-bit application would successfully make COM calls to an ActiveX EXE. The only equivalent of an out-of-process ActiveX EXE in .NET is class library dll. I have created a .NET dll and checked the 'Register with COM' box in Project Properties -> Build.

But i'm still unable to call any methods from the 16-bit application. Any suggestions?

Thanks,

You may need to use a 32-bit Visual Basic ActiveX EXE (as an automation proxy/host) to talk to the
..NET DLL. The 16-bit app can then make all of its calls (cross-process), to the .NET DLL, through
the 32-bit ActiveX EXE.
