I have documentation that states the following:

In addition to the C++ library, there are several
ways to connect your application to the library:
– Via SWIG (Simplified Wrapper and
Interface Generator, www.swig.org) you
can use KNI from several scripting and
programming languages on different
operating systems. Currently Python is the
only supported language (tested on
Windows and Linux).
– On the Windows platform, there is an ActiveX control, which can be used from different programming languages like C++, VB and Delphi.

My question is, what does this ActiveX control look like? What is the file extension? I'm in the folder with the source code, I just don't know what the control looks like. I'm not used to COM and this is important because I need to interface to Labview. Any ideas?
