Producing Serial Numbers

[alpertunga65]

Hi everone,

I would like to produce a serial which will have 4 members.

The first, the second and the fourth members will be always CAPITAL Letters and the thirth one is always NUMBER.

Here is an example for the format: AC3H

Each member will change in any line and never match... I would like to produce it by a button or a button for each one.

The last important point for this issue is; I would llike to identfy the total number of serials. I mean I want to produce serials how much I want...

Thanks a lot...

Are the numbers and letters totally random or are they supposed to mean anything? or do you want them to increment is some way e.g.

AA0A
AA0B
AA0C
...
...
AA1A
AA1B
etc

Total number of combinations is 175760 assuming you are using 26 letters and 10 numbers and there are no exclusions - do you mean you want to know how many have been used?

Has the Seriel Number any specific meaning?

Would starting with AA0A and going through to ZZ9Z or the suggestion of CJ London serve your purpose well?

If you have a random Seriel Number generator then you will have to check to see if the Seriel Number has already been used and this check will take longer and longer as time goes on.

Hi highandwild,

Thanks for quick reply.

As I told to CJ London; the serial numbers dont have any specific meaning and increment.
Both will be random and I will check if ny onf them has already been used by a checkbox.
