pcode myfun

Note that pcode is not high security: it is "nuisance security".

Thank you, I read for experts who say that pcode not the perfect solution, for this reason I asked the question...

But also, I use in my code "Parfor", and when I run the .p file I receive a error " Parfor statements are not supported in P-code script files.

[Bruno Luong]

Athoner option if compile the code using MCC if you have the toolbox.

There is other solution is encrypt using HASP key. None of the solution is perfect. There is no suhc thing.

Cracking pcode and possibily MCC become trivial for those how have access to decrypt SW.

Thank you,

Juste How I can add an expiration date and time to my pcode file?

If you are willing to rely on the system time you can use now to retrieve the current date and compare it to an expiration date. If you don't trust the user, then you should host your own server that returns a time. Don't use the publicly available options, as you don't control whether they allow API access and might go down without warning.
