What's the requirements of your assignment.

Do you have to use classes? What about splitting when you get a pair?

[jbennet]

i can do it however i want - just has to be in VB.NET 2003
the brief is simply to make a blackjack/pontoon game

[jbennet]

right now it works very well but i think i may remake it and use an array for the cards - only i used classes is i got the carsds to be random and have a human friendly name by using a class module shown below:

OptionStrictOff
OptionExplicitOn
 
FriendClass card
'Card.cls - Class module for the cards used in the blackjack game
'James Duncan Bennet 2006 - [e-mail]
 
Public name As String
Public id As Short
Public value As Short
 
Sub main() 'This doesnt have to be called main, but cant be bothered changing it now :)
 
id = CDbl(CStr(Int(Rnd() * 13))) + 1
 
'From the .NET version, dont know if its ok - The +1 is to stop id of 0, could do without it but hey....
 
Select Case id
 
Case 1 : name = "Ace Low"
value = 1
Case 2 : name = "2"
value = 2
Case 3 : name = "3"
value = 3
Case 4 : name = "4"
value = 4
Case 5 : name = "5"
value = 5
Case 6 : name = "6"
value = 6
Case 7 : name = "7"
value = 7
Case 8 : name = "8"
value = 8
Case 9 : name = "9"
value = 9
Case 10 : name = "10"
value = 10
Case 11 : name = "Jack"
value = 10
Case 12 : name = "Queen"
value = 10
Case 13 : name = "King"
value = 10
Case 14 : name = "Ace High"
value = 11
 
End Select
End Sub
EndClass

i just initialise the card by doing e.g dc1.main which randomises it
