How do i do this?

I have a list box of numbers and letters that are suppose to be cards (BlackJack 21):

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, A

J, Q, K = 10
A = 11 or 1

How do i make it auto detect what the ACE should be if totaling the cards dosnt go over 21 and having it read how many aces are in the hand.

The problem I'm having is after totaling up the (ACES already in hand) values for the cards and then another ACE gets drawn the old ace remains a 10 which makes it go over 21. For example:

first calulation would add these cards as 8:
1, A, 6 = 18  

then another card is drawn:
1, A, 6, K = 28
After the King is drawn it automatically brings it over 21 because the previous ACE was a 11.

Lets say 2 more cards were drawn:
1, A, 6, K , A, 1

if added right this would of been a perfect hand
but for me its adding 30 because its only deciding on the last ace.

I need it something like this: (lets pretend this was possible in a hand)
A,A,A = 13
A,A,A,A = 14
A,A,A,A,A = 15..etc
A,A,A,A etc...(21 x A's) = 21

Having it autodetect the best use for A's (1 or 11) for each A in the deck.
How can i make it make the best decision for totaling up the values to have it =21 or <21 or closest to 21 with multiple aces.

so if ace is drawn get the value

A,A should = 12

a = 11  then ace ir drawn so if next card = Ace then another If > 21 then ace = 1

Just add a condition if ace is the next drawn card

This may not be the shortest or cleanest way to do the calculation, but it does work.  I used an array here instead of a listbox, but you can modify that easily enough.  The key is counting upi the number of aces in the hand while totalling up the rest fo the cards, then taking a look at the number of aces and calculating the total based on the number of aces present.  You can loop through this as each card is added to the hand.

Private Sub Command1_Click()
    Dim aCards(), intTotal, intAceCount
    aCards = Array("3", "A", "5", "A")
    For x = 1 To UBound(aCards)
        Select Case aCards(x)
            Case "1", "2", "3", "4", "5", "6", "7", "8", "9", "10"
                intTotal = intTotal + Val(aCards(x))
            Case "J", "Q", "K"
                intTotal = intTotal + 10
            Case "A"
                intAceCount = intAceCount + 1
        End Select
    Next
    If intAceCount > 0 Then
        Select Case intAceCount
            Case 1
                If (intTotal + 11) > 21 Then
                    intTotal = intTotal + 1
                Else
                    intTotal = intTotal + 11
                End If
            Case 2
                If (intTotal + 12) > 21 Then
                    intTotal = intTotal + 2
                Else
                    intTotal = intTotal + 12
                End If
            Case 3
                If (intTotal + 13) > 21 Then
                    intTotal = intTotal + 3
                Else
                    intTotal = intTotal + 13
                End If
            Case 4
                If (intTotal > 14) > 21 Then
                    intTotal = intTotal + 4
                Else
                    intTotal = intTotal + 14
                End If
        End Select
    End If
    If intTotal > 21 Then
        MsgBox "Bust"
    End If
End Sub

just have to ask, which card in the deck is the 1 that you show in your original list:

1,2,3,4,5,6,7,8,9,10,J,Q,K,A ==> 14 cards per suit (there are only 13, 2...10,J,Q,K,A - there is no 1)

I had to laugh when I read your post, Arthur_Wood.  I do play cards and still didn't notice.  Too fixated on solving the ace issue and didn't notice the 1.  Good catch!

After looking at the code I posted I quickly saw that there's an easy way to cut out a bunch of it.  Here the revised, and much shorter, code.



Option Base 1

Private Sub Command1_Click()
    Dim aCards(), intTotal, intAceCount
    aCards = Array("3", "A", "5", "K")
    For x = 1 To UBound(aCards)
        Select Case aCards(x)
            Case "2", "3", "4", "5", "6", "7", "8", "9", "10"
                intTotal = intTotal + Val(aCards(x))
            Case "J", "Q", "K"
                intTotal = intTotal + 10
            Case "A"
                intAceCount = intAceCount + 1
        End Select
    Next
    If intAceCount > 0 Then
        If (intTotal + 10 + intAceCount) > 21 Then
            intTotal = intTotal + intAceCount
        Else
            intTotal = intTotal + 10 + intAceCount
        End If
    End If
    If intTotal > 21 Then
        MsgBox "Bust"
    End If
End Sub
