I have a textbox that can contain any number of space delimited strings.
Each string must be 3 digits.
The first 2 digits must be letters. The third must be a number.
AA4 BE9 II4 Valid
AA4BE9 Invalid as there is no space
AA4 BEK Invalid as the last digit is a K not a number
AA9 PO5 WW3 QQ4 invalid as there are 2 spaces between WW3 and QQ4
I'm using vb 2008 with asp.net 3.5.
