IF AND THEN ELSE problem

I am having trouble with a blackjack game I am creating

I have buttons 1 - 13 (A-K)
I have 5 Textboxes which when the above buttons are pressed displays the values in the textboxes.

I also have one more textbox which adds up the values of the above 5 textboxes to give your Black Jack Total.


The problem I have is if an Ace (11) is in one of the textboxes and the Total Value exceeds 21 i need to have the Ace (11) change its value to 1 instead.

textbox 1 - 5 will be the card values
textbox6.text will be the total Value

I have tried......

Code:

Code:

---

if textbox6.text > 21 and textbox1.text = 11 then textbox1.text = 1

---

This seems to work fine however it only solves the problem of an Ace (11) appearing in textbox1.text so i tried to repeat the code with the other boxes...

Code:

Code:

---

if textbox6.text > 21 and textbox1.text = 11 then textbox1.text = 1
if textbox6.text > 21 and textbox2.text = 11 then textbox2.text = 1
if textbox6.text > 21 and textbox3.text = 11 then textbox3.text = 1
if textbox6.text > 21 and textbox4.text = 11 then textbox4.text = 1
if textbox6.text > 21 and textbox5.text = 11 then textbox5.text = 1

---

However this does not work and my program freezes?

Can anybody give me some code to resolve the problem. Not really bothered what the problem is just need a solution its driving me cra

Thanks mate now im gonna get no help.

I marked that one as resolved because no body was replying

See this thread http://www.vbforums.com/showpost.php...51&postcount=8 for some good advice on dealing with cards.

The first problem you need to address is your checks. What if "B" is in textbox1? Is that greater than 21?

Doesn't look like it was marked resolved to me.

Hi,

You can try this;

vb Code:

If TextBox6.Text > 21 And TextBox1.Text = 11 Then
            TextBox1.Text = 1
        End If
        If TextBox6.Text > 21 And TextBox2.Text = 11 Then
            TextBox2.Text = 1
        End If
        If TextBox6.Text > 21 And TextBox3.Text = 11 Then
            TextBox3.Text = 1
        End If
        If TextBox6.Text > 21 And TextBox4.Text = 11 Then
            TextBox4.Text = 1
        End If
        If TextBox6.Text > 21 And TextBox5.Text = 11 Then
            TextBox5.Text = 1
        End If

Oh my apologies I thought I did i'll redo it

No that doesn't work unfortunately?

Hi,

In my application it does work in this button click event:

vb.net Code:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        If TextBox6.Text > 21 And TextBox1.Text = 11 Then
            TextBox1.Text = 1
        End If
        If TextBox6.Text > 21 And TextBox2.Text = 11 Then
            TextBox2.Text = 1
        End If
        If TextBox6.Text > 21 And TextBox3.Text = 11 Then
            TextBox3.Text = 1
        End If
        If TextBox6.Text > 21 And TextBox4.Text = 11 Then
            TextBox4.Text = 1
        End If
        If TextBox6.Text > 21 And TextBox5.Text = 11 Then
            TextBox5.Text = 1
        End If
 
    End Sub

Can explain a little more what's wrong and witch error you got.

Ok i think i have something working now, i'll finish it off and let you know

Could we at least pretend that we know the difference between strings and integers?

Make

Option Strict On

the first line of your program and you will see how bad it is.

At a minimum it should look like this

Code:

---

        If CInt(TextBox6.Text) > 21 AndAlso CInt(TextBox1.Text) = 11 Then
            TextBox1.Text = "1"
        End If

---

though it does nothing for the case where the user enters something other than numbers into a textbox. See Integer.TryParse, please.

why does it have to be like that? what is the difference they both appear to do the same function
