Could you explain what you mean by "time usage validation"?

for example..
i will give my database to my friend as a trial, to work and if he try to
open the database after 10 or 20 days to see a pop up windows said " the
trial version has expired"

any ideas??

Just by the nature of desktop applications, it's very hard to make this
*really* secure: someone sufficiently determined and skilled can crack any
such scheme. But for some pointers see

You would be better off setting a limit to the number of records a trial
database would contain, i,e 25, 50, 100, etc.... Make sure you create a
*.mde file before giving to your friend, finally use the shift-bypass
function. I am not a fan of the Access security, I set all security features
in code from an Autoexec function.
