[RESOLVED] VB2010 Simple calc program needs help

Hello All,

This is my first post, so if I'm doing something wrong, please let me know. I'm brand-spanking new to programming and I need a little help. I bought a membership to learn visual studio.net and started with the beginner series. I'm less than a third of the way through the videos and started a little programming of my own. I need help finishing it off...

Here is the code:

Code:

Public Class Form1

    Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
        Dim Mortgage As Double
        Dim Electricity As Double
        Dim gas As Double
        Dim SWgas As Double
        Dim Car As Double
        Dim Water As Double
        Dim Cable As Double
        Dim Trash As Double
        Dim CCB As Double
        Dim Income As Double
        Dim Xtra As Double
        Dim Phone As Double
        Dim Retire As Double
        Dim Save As Double

        Mortgage = Double.Parse(txtMortgage.Text)
        Electricity = Double.Parse(txtElectricity.Text)
        gas = Double.Parse(txtGas.Text)
        SWgas = Double.Parse(txtSWgas.Text)
        Car = Double.Parse(txtCar.Text)
        Water = Double.Parse(txtWater.Text)
        Cable = Double.Parse(txtCable.Text)
        Trash = Double.Parse(txtTrash.Text)
        CCB = Double.Parse(txtCCB.Text)
        Income = Double.Parse(txtIncome.Text)
        Xtra = Double.Parse(txtXtra.Text)
        Phone = Double.Parse(txtPhone.Text)
        Retire = Double.Parse(txtRetire.Text)
        Save = Double.Parse(txtSave.Text)
    End Sub
    Function calculateIncome(ByVal Income As Double, ByVal Xtra As Double) As Double
        Return Income + Xtra
    End Function
    Function calculateBills(ByVal Mortgage As Double, ByVal Electricity As Double, ByVal gas As Double, ByVal SWgas As Double, ByVal Car As Double, ByVal Water As Double, ByVal Cable As Double, ByVal Trash As Double, ByVal CCB As Double, ByVal Phone As Double, ByVal Retire As Double, ByVal Save As Double) As Double
        Return Mortgage + Electricity + gas + SWgas + Car + Water + Cable + Trash + CCB + Phone + Retire + Save
    End Function
    Function calculatePlaymoney(ByVal calculateIncome As Double, ByVal calculateBills As Double)
        Return calculateBills - calculateIncome
    End Function
    Sub displayNumbers(ByVal calculateIncome As Double, ByVal calculateBills As Double, ByVal calculatePlaymoney As Double)
        txtTotalincome.Text = Format(calculateIncome.ToString(), "Currency")
        txttotBills.Text = Format(calculateBills.ToString(), "Currency")
        txtLeftover.Text = Format(calculatePlaymoney.ToString(), "Currency")
    End Sub

End Class

I would really appreciate any help you all could provide. Not looking for gimme's, but some nudging in the right direction is/would be awesome. I've also included a screenshot of the form in case it helps...


Thanks,

Mike

You might do better to ask an actual question rather than just posting some code and asking us to do something with it when we don't really know what you're looking for. What exactly are you trying to do and what exactly are you having trouble with?

You are right, my bad.

I'm looking to capture the the bills and total them. Also, capture the income and total it. Then subtract the two and display the result in the text boxes as labled. I'm not sure if I'm heading down the right path.

I'm also looking for a good syntax reference...

thank you,

Mike

Looks ok to me, just handle the calculate button event and sum up your bills, then set:

Code:

---


totalBills.Text = total.ToString()

---

Then sum up your total income and set the income textbox:

Code:

---


totalIncome.Text = income.ToString()

---

Finally, set your difference with (income - total).ToString()

Thanks Monk... now where do I "call" them? I added the code but when I click the button nothing happens...

Thanks.

Thank you Zach... I hate to bother you... but would you briefly explain why you did what you did?
