PDF "problem" and Javascript question
I am planning to create several reports that ppl can download after paying for them.
As usual I will offer a 30 day money-back guarantee.
One of the things that I am a bit worried about is that somebody buys the PDF, then ask the money back and still keep using the repport.
In the software I develop I always do a check on my server (over TCP/IP) whether the license is genuine, meaning, paid for and allowed to run on that machine (using the local IP address and a license code). If the person running that piece of software requested the money back then the software will not run. The value returned from the server tells the software not to run.
I do know that it is possible to insert Javascript into PDF Files.
Would it be possible to create some JavaScript that does exactly what I described above?
Hoping to hear from you all.
