Is it possible to call the new .Net routine from within my VB6 app? How?
You have to use .NET to produce a COM DLL by including GUIDs and the
correct attributes. Once registered then you then can call it from VB6.
The downside for using this to add a few new routines is that it is
easy in .NET to create code that is not compatible with COM (exposing a
generic class is a no no for example) Plus you have a huge
multi-megabye runtime you will have to add to your install. Plus a raft
of new install issues that are unique to the .NET runtime.
None of it is impossible but it is a step that shouldn't be entered
lightly and there are compromises involved.
As for actually using .NET to build a COM DLL you should go to one of
the dotnet groups for that.
