Hi EE,

I need help in generating the Unique Number of 4 character length.

Criteria is as follows :
  1. String will always start with alphabet
  2. Another 3 characters will be a combination of alphabets (A-Z) and digits (0-9)
  3. Once the number generated it could not be repeat

A001, A999, ZD01, DA9P, SXS8 etc...

I need to write a logic for the same in my ASP.NET (VB.NET) based web application.

Please provide a direction.
