Hi Quartz,

I seem to recall an especially interesting post from Harlan Grove on the
topic of creating unique numbers.

It might be worth performing a google search for Harlan's Unique Number
contributions.

Thanks Norman.

I don't need sequential numbers, just unique ones. I don't really want to
mess with the registry nor maintain a separate file to track the numbers.

That's why I was looking for a numbering method that could be generated
based on date, time, and user computer ID. Do you think my concept would
work
to generate a unique number?

Even if two users happened to open the template file within the same
second,
their unique box ID would still render a unique number. I'm just worried
about numbering overlap between years, etc. What do you think? - Do you
know
any other websites to check?

Thanks much for your help!

I am using Office 2003 on Windows XP.

I have a form built in Excel that will be placed in an Outlook folder
making
it accessible to all users within our organization.

Each time a user opens this form a unique number must be generated on
the
form.

Suppose I convert the Excel date to a value: e.g. Aug 17, 2005 becomes
38363
and for time I use 5:34:15 pm = 173415. Now suppose I add these two
numbers
together and also add the user's computer ID to this (each user must
have
a
unique computer ID) for example: 83177.

This would then be 38363 + 173415 + 83177 = 294955

Question: Since this value is date and time based and combines a unique
computer ID, would this ALWAYS generate a unique six digit form number?

The form number does need to be unique, but not necessarily in sequence
Any
one have any other suggestions?
