Learning help please

Hi all,
I am trying to teach myself the basics of programming before I take a course involved in it. I have been working through some sample pieces and i was wondering if someone could help me out with a little bit of code.

basically the problem i have is using check boxes. I want to select a certain amount of ice cream toppings and I have each check box done separately.

basically in the code for each text box i have this

Code:

---

Private Sub chkSprinkles_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles chkSprinkles.CheckedChanged
        If chkSprinkles.Checked Then
            totalToppings += 1
        End If
        totalToppings += 0

    End Sub

---

i figured doing this for each would allow me to raise a running total (totalToppings)

since each topping costs one dollar i have the totalToppings incrementing when each one is ticked. I want to then display this total in a text box.

I assumed it was something like this. would this not display the total in the text box

Code:

---

Private Sub toppingPrice_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles toppingPrice.TextChanged
        toppingPrice.Text = totalToppings
    End Sub

---

thanks alot

Moved From The CodeBank

I am lost as to what has happened to my post. Let me know
Thanks

:confused: It is right here. If it wasn't, you couldn't have posted in it.

The CodeBank (where you originally posted it) isn't for questions. It is for sharing code with other members.

You said the toppings cost a $1.00 each, but I don't see you adding a $1.00 to anything.

The Text_Changed event fires when the text gets changed and not when some variable changes.

You can add the 'toppingPrice.Text = totalToppings' in the CheckedChanged event of each checkbox.

At the moment I just want the client to be able to press on a bunch of check boxes. and for each time one is clicked i want totalToppings to increase by 1.

This will allow me to say i have 5 6 7 8 etc amount of toppings.
Then i will convert it to say $5 for 5 toppings.

how do i make the total display inside the text box

Code:

---

    Private Sub chkSprinkles_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles chkSprinkles.CheckedChanged
        If chkSprinkles.Checked Then

            totalToppings += 1

            toppingPrice.Text = totalToppings.ToString

        End If
    End Sub

---

Thanks but let me clear up,

totalToppings DOES hold the amount of boxes checked off.

So if i called totalToppings it should display the amount of boxes that are checked off.

thanks sorry for all the troubles

You can have one event handler to handle for all the checkBoxs’ CheckedChanged event and add or subtract one according to the checked state of the control. Here is an example:

vb Code:

Dim totalToppings As Integer
 
Private Sub CheckBoxs_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles CheckBox1.CheckedChanged, CheckBox2.CheckedChanged
 
    Dim cb As CheckBox = DirectCast(sender, CheckBox)
    If cb.Checked Then
       Me.totalToppings += 1
    Else
       Me.totalToppings -= 1
    End If
    Me.toppingPrice.Text = totalToppings.ToString("C")
End Sub

Aah, got it...yep, the above soluton is the right way. If you want to do it for each checkbox separately:

Code:

---

    Private Sub chkSprinkles_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles chkSprinkles.CheckedChanged
        If chkSprinkles.Checked Then

            totalToppings += 1

            toppingPrice.Text = totalToppings.ToString

        Else
            totalToppings -= 1

            toppingPrice.Text = totalToppings.ToString
        End If
    End Sub
