If fact, we have here only two methods because the second one is
non-existent.
It would be great if method two existed, but because of the fact that
ThinkC's
project format is private it is unrealisable.

What method three refers to, is exactly what my MCL <-> ThinkC interface
does.
It enables you to easily load and execute code resources generated from
ThinkC
projects.

The latest version of this interface is available as
