First of all, I apologize for the delay and I thank Michael for what he wrote about me (actually I've been attending for more
than twenty years Autolisp and surroundings), I apologize also for my poor English (Google translator) who sometimes
creates misunderstandings.
I confirm what I wrote in my post #2 "Yes, I confess it's an unhealthy idea, I wanted to see which users use certain functions ..."
since I care a lot about my reputation I wanted to be more detailed in my idea.
My intent is NOT fraudulent but simply this (example):
Alfa, Beta and Gamma are three of my clients and have been using some of my programs for many years.
I state that I am not a real programmer but I have created a standard for for the design of stainless
steel catering in cruise ships environments (kitchens, bars, refrigerator rooms, etc.) with special functions
which force users to draw according to pre-established rules (Layers, styles, dimstyles, etc.).
Every user of Alfa, Beta and Gamma can use my programs by authorizing them through a special command
which creates an email in which there is the name of the user, hard disk serial number, CAD serial, etc.
I reply to this email by sending a custom activation file.
All this sometimes makes me lose a lot of time because if a user changes the PC, the PC changes user or for some reason
the authorization doesn't work I have to answer in a short time to make sure that the operator can use my functions
without the interruptions that are foreseen when using the program in a free way.
Lately for the Gamma customer, for not having multiple activation requests,
I created a command that allows the authorization an autonomous and unlimited way without asking anything
but that should only be used in the Gamma company.
It has been a while since the UserX of Gamma client goes to work to the Alfa client (for example) and theoretically could
copy my programs to activate them at that client or at any other.
My simple need was to check who was using my programs and with which client.
However, I believe I will abandon the way to delete the generated message so that it remains a trace
to those who sent it so as not to generate doubts also about my activity with the customer.
I hope I have translated it correctly so as not to generate incorrect interpretations.
Thank you all.
