Hi,
This sounds like you would want to generate the keys from a database to me, not
the form. For example, store things in a relational database table and make the
primary key a sequential number, and let the records get their unique numbers
automatically as you add them to the database. If you do this, you won't even
need to use a form to fill in the sequential numbers. Two database candidates I
can think of right away are MySQL and SQLite. But that depends on how you want
to handle the data once you get it.
Thanks.
Jim

Hi. There is a lot of things to consider, and the best solution would be to
develop it from scratch yourself.
You have to decide, for example, where you will store your references, and
ensure the generation is concurrency safe - that two users will never get the
same reference.
It is not hard!
If you can ask us more specific questions directly related to your solution of
the problem we can try to answer those.

Hello friends, I want a solution, which should generate a sort of numbers, and
should be in a sequence, the number is to be used as the order number, and
should be of 4 digits long only for time being.
for example, on first order if it generates 5412, the next should be 5413 and
so on.
do you have any working template, and which way I should I go, the java scr or
a program.
please attach me in person if you have one, if the generated string is an
alphanumaric or more than 4 characters long, I don't mind it.
Thanks, Jitendra.
