Thanks. One more question. How would I check to see if the setting XX creates a line? Can you give me an example for one of the methods?...

I have an assignment that I'm having problems with and I was wondering if you could help me. What I have to do is to generate a 5x5 two-dimmensional array with 25 two-digit numbers, but I have to make sure there are no duplicates. Then I have to cover 10 randomly picked numbers from the array with "XX", but I have to make sure that none of the 10 covered numbers make 5 in a row either horizontally, vertically or diagonally.
