Generating all possible string combinations

Hi,

I wish to write a program that generates all possible combinations of strings of length five consisting of the numbers 0-9 and all upper and lower case letters/

Currently I'm using five nested for loops to do this, however this is VERY slow.

Can anyone suggest any better solutions?

Thanks in advance.

You could really do with a permutations and combinations library to produce your 6471002 combinations. If i've time, i'll look for one.
