>From what I am seeing you are using a predefined COM interface
IBisComServer that you are referencing from an interopt dll or a typelib
that you created from tblimp. In this case you are creating the object
latebound in a sense BUT you are using the definition of the interface
which will perform a single cast (QueryInterface) and then you will be
early bound. If the typelib or interface GUIDs in your original dll
change, you will need to recompile your .NET assembly with the new dll/tlb
reference just like good old straight COM.
You are on the right track in creating the object with the Activator you
just need to stick with the object data type (i.e. not a predetemined type
so it's late-bound) and use something like the Type::InvokeMember()
methods. I do have to admit though, I have only done late bound with .NET
components and not COM so there could be more to it then jumping from the
createinstance right into the Type::InvokeMember() methods.
