I need a regular expression that would validate string like this.

aa5677

Any 2 literal characters and then any amount of digits from 1 to ...
aa345k is not valid.

Can someone write this for me.

Thanks
George.

Ah, change ( * ) to ( + ), like this

^[a-zA-Z]{2}\d+$

it will require at least one digit

Yea, thanks
I figured that one myself
After an hour of reading MSDN I gave up and wrote to you guys. But now I
know something about Regex
