I have written a little application what I would like to do is release it with some inbuilt protection. I would like to make it unrestricted working for 30 days afterwhich it would require the user to enter a code that would remove the restictions.

Any ideas on how to acheive this would be very welcome.

I have found solution called www.sdprotector.com which easily time trials FM runtime databases, if anyone is interested in converting their databases into runtimes, having it professionally packaged and time trialed drop me a line.

Sorry MACS this is for Windows only

Could you write a startup script with user abort turned off that checks for a registration code, and if not there, then checks for a date compared to a pre-entered startup date (auto-entered the first time a user runs a solution). This could be done with a few global fields and a single script.

FYI, Brudders, it's Mac, not MAC.
