RE: [DL] Card Dealer

Hopefully not getting repetitive here ...

Yes, the easiest way I've seen by looking at card type
programs in C++ is just to create a 52 item array with
each item defined as a card.  Shuffle the deck by
going through each card position, and SWAP it with a
different card in a different position.  By the time
you get to the end of the deck, all the cards should
be randomized.  Anytime you remove a card from the
array, really do it.  Reduce the array by one size,
and put the card in a hand or discard pile.  When you
need to reshuffle, put all the cards back.

Never messed with VB though.  That being said I looked
through a bunch of VB help websites and found this:
http://www.vb-helper.com/HowTo/cards.zip
which I believe is source for a card shuffling
program.
Something you may want to look at.
