I have a distributed app (A2k & A2k3) with users paying a fee on a monthly
basis up to lots of 12 months. Currently I provide the user with a 12 digit
code that is specific to their registration name and current month/year. For
example it takes the name ABC Company looks up a number that has been
assigned to each letter of the alphabet of the company name and takes the
month (times x) and year (divided by y) and performs a calculation x times
to spit out a 12 digit code.

I would like to just make it a yearly fee specific to the company between a
start date and end date and far more efficient then what I am doing now and
was hoping someone might have a similar function that I could change to
suit. Each time the app starts it will check that the registration is
current and advise the user when there is only 30 days left.
 
Hi Ian,

Thanks for your post. If I understand correctly that you are looking for a
registration function meeting your specific requirements to protect your
distributed application. Based on my research, it seems there is not an
easy way to find an existed registration function shared on the network. I
am afraid that you have to code it yourself.

I found the following article for your reference.

In the meantime, please feel free to post in the newsgroups if you would
like further assistance on the function coding.
