Patrick,
I've never actually used Eyeon Script at all, so this is going to be a
complete guess on my behalf. Put the DLL Name back to eyeonscript.dll
and then try using require "eyeonscript". Making sure that eyeonscript
is in whatever folder Lua thinks is the default scripts folder. Since
lua can (and should) scan in the order of lua, lib, and dll (or
something like that) so it should load the module. This should
probiably be the first line in your script. Another way of doing this
in code would be to have lua load the library by name, I believe this
can be done with lua_dofile(luaVM, "./eyeonscript.dll") but you may
have to use the lua_loadlib function instead.

Hi Jeremy,
Thanks for your answer. Yes that is exactly the product.
I already contacted their customer support and they helped me to
connect to
C#.NET from EyeonScript via LuaInterface.
But I would like to connect to EyeonScript from C#.NET.
This is basically what I did:
- I made a sample project for LuaInterface in Visual Studio (see
attachment)
- I renamed eyeonscript.dll to lua50.dll (so that LuaInterface would
load
the renamed eyeonscript.dll which seemed to work).
- I tried to type some EyeonScript specific commands and got the error
messages attempt to call global `Fusion' (a nil value) (see below).
- When it didn't work I tried to find answers in many forums etc.
which
didn't work either. You are the first one to answer :).
Could you maybe explain your steps below in more detail? Or even point
out
what I would need to change in the attached program?
It makes sense to try to load the Eyeon Script enviroment (which is
what I
tried by renaming the files) but I don't know how to do it :).
Thank you very much for your help
Patrick

If this is the same thing as Eyeon Script that ships with Fusion 5
(http://www.eyeonline.com/Web/EyeonWeb/Products/fusion5/fusion5.aspx)
then here is what I would say:
1) Make sure that your loading the proper lua environment.
2) Make sure that your either requiring the Eyeon Script environment,
or
loading it after you load Lua.
3) In the case of 2 make sure that you have linked the Eyeon Script
environment with your script instances.
4) Since you paid for the product, contact their customer support and
ask
them whats wrong :)
