Make Database work for some period of time?

[cikul]

I need some kind of shareware version of my database.
I want to make database work for exmpl. for 7 days and everytime you start the database it says "You have # days left" and after 7 days to stop working, also not to accept F5 key for bypassing startup options. How can I do this?

You could have a date field in a table that starts as null.
When you start your database, the startup procedure checks if this field is null, if it is null it populates it with the current date.
Your "days left" routine compares this date plus the number of days you want the database to work with the current date.
