LC Server & Server Based Stack?

[Rick Harrison]

Hi Mike,

Ok, so the server and my open LC stack are using
different engines or are different “instances”.  If they
are on the same computer it seems to me that one
might be able to get the two to talk to each other
through the computer system’s clipboard in theory.

I haven’t had much luck with getting the contents
of a variable into the clipboard on the server side
yet.  It keeps throwing weird errors at me.
Can you think of an easy way to do that?

Thanks,

Rick
