I will agree that licensing and demo versions
or modes are a fact of life -- but permanently
eating my memory in order to implement them doesn't
have to be.
Do you have any objections to solutions that
do not require storing data for the life of
my device just to monitor your 30-day trial
period? Your question about the dialog box
seems to indicate that you are still intent
on using that method. How about some alternatives?
For example: store the creation date in any
database your application uses. If the current
date is 30 days after the date stored with the
data, refuse further access. This gives you
a time limited trial, but keeps the time-keeping
information from becoming a permanent addition
to my memory.
Or: consider other forms of application
crippling than time limiting. JFile limits
trial users to 2 databases -- every feature is
fully functional, and there is no time limit.
But if you want to create 3 different kinds of
databases, you are forced to register.
