2d array question...

[Len via DotNetMonster.com]

I have to set up a 2d array(13, 4) containing a deck of playing cards.
What I am wondering is how to correctly set up the array in the first
place, and then how do you access the information once the data is in the
array? Button clicks tell the array the rank and suit of the card chosen.
The output should be a prompt telling the user what they have in their hand
if anything at all.

Here is what I have thus far:

****

Dim countEntered(13 ) As Boolean
Dim suitEntered(4) As Boolean
Dim x, y, z As Integer

Private Sub Form1_Load(ByVa l sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load
Dim handResult(13, 4) As Boolean
'Fill arrays
countEntered(1) = False
countEntered(2) = False
countEntered(3) = False
countEntered(4) = False
countEntered(5) = False
countEntered(6) = False
countEntered(7) = False
countEntered(8) = False
countEntered(9) = False
countEntered(10 ) = False
countEntered(11 ) = False
countEntered(12 ) = False
countEntered(13 ) = False
suitEntered(1) = False
suitEntered(2) = False
suitEntered(3) = False
suitEntered(4) = False
End Sub

*****

Here is what I have entered for button clicks....

Private Sub Button13_Click( ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button13.Click
countEntered(13 ) = True
Display.Text = "Ace"
y = y + 1
End Sub

Private Sub Button16_Click( ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button16.Click
suitEntered(1) = True
Display.Text = Display.Text & " of Spades"
z = z + 1
Return
End Sub

*****

My intent is to change the boolean value to true once the proper buttons
are clicked. Am I going about this the right way? Then, once the boolean
values are established in the array, how do I associate them with the card
value and return what is in the player's hand?

I'm a little confused. Any help will be greatly appreciated!

Re: 2d array question...

You might have better luck using a class to define a single playing
card and then create an array or cards. You might even consider a
class to indicate a Hand which can hold one or more Cards. You might
also have a class called Deck which models a deck of cards. The Deck
class could have a Deal method that returns a Hand. Here is some
simple code that should give you some ideas.

Public Enum eSuit
Hearts
Clubs
Diamonds
Spades
End Enum

Public Enum eRank
Joker
Ace
Two
Three

'fill in the rest of the ranks here

King
End Enum

Public Class Card
Public Rank As eRank
Public Suit As eSuit

Public Function ToString() As String
'Code to display card here
End Function
End Class

Public Class Hand
Public CardsPerHand As Integer
Public Cards As ArrayList

Public Sub New(cardsperhan d As Integer)
Cards = New ArrayList(cards perhand)
End Sub

Public Sub AddCard(c As Card)
Cards.Add(c)
End Sub
End Class

Public Class Deck

Private _topCard As Integer
Private Cards As ArrayList

Public Sub New(cardsindeck )
_topCard = 0
Cards = New ArrayList
FillDeck()
ShuffleDeck()
End Sub

Public Function Deal(numcards) As Hand

Dim h As Hand

If (_topCard + numcards) < Cards.Length Then
h = New Hand(numcards)
For x As Integer = 0 to numcards-1
Hand.AddCard(Di rectCast(Cards( _topCard),Card) )
_topCard += 1
Next
End If

Return h

End Function

Private Sub FillDeck()
'Code to fill the deck with individual cards
End Sub

Public Sub Shuffle()
'Code to shuffle the elements of the ArrayList here
End Sub
End Class

Re: 2d array question...

I thank you for your reply, but I wasn't clear enough with my question...
This has to be set up as an array of Boolean type. I will be greatly
appreciative for any help I can receive. I have to create a 2D Boolean
array of size (13, 4) The contents contain a deck of 52 cards, of which
they are broken down into the obvious, hearts, spades, clubs, and diamonds,
and then obviously, the rank cards.

My question is this: I believe I have set up the array correctly, and have
it loaded when the form loads, however, I am having trouble understanding
how to access the data in the array, and then associate that data with a
particular card that the user enters. A full hand is to be analyzed by the
program and is to return a message as to whether the user has a hand that
contains anything of value: ie One Pair, Two Pair, etc.

I have included the code below.

Dim handResult(13, 4) As Boolean
Dim count(13) As Integer
Dim suit(4) As Integer
Dim x, y, z As Integer
