Hi developers,
Can anybody answer this "simple" question:
How to protect ICAD lisp program? I mean the real protection, not Autodesk protect.exe and kelvination, which are easily decrypted. I tested LispPro demo (the N1 in search engines) with the negative result. *.exe file, created by LispPro simply doesn't work in ICAD (because of ICAD? Windows XP? My mistake? - though I don't think so) Some other demo samples, making good impression,
don't work with ICAD and are intended for AutoCAD only. Maybe ICAD VBA can help to solve the problem? (to protect lisp files) Thank you for any comments and possible help.

Boris,

There is no such thing as secure code!

There are just difficult locks to obtain the code.

I recall that someone has placed lisp code inside VBA's P code and then password protected it.

It just seamed such a waste because VBA exceutes much faster than Lisp and I couldn't understand the rational behind it.

There may be some missing objects in VBA that Lisp code can overcome and I have used this myself and this could be their reason.

Anyway you can lock away your Lisp code in VBA if you like.
