Hi all

I've been editing some code I found on here from a while back and am up to trying to print out the data I store in an array. I've been trying for a bit and just don't understand it very well. Could someone give me a hand :)

Daily Summary Class

Public Class DailySummary
    Inherits Order

    Private orders As New ArrayList()
    Private totalOfPlainSausages As Double
    Private totalOfOnions As Double
    Private summaryDate As Date

    Private totalAmountDue As Double
    Private totalAmountPaid As Double
    Private totalChangeDue As Double
    Private totalSalesTax As Double
    Private theOrder As Order

    Public Sub New(ByVal aNumberOfPlainSausages As Double, ByVal aNumberOfOnions As Double, ByVal anAmountPaid As Double)

        MyBase.New(aNumberOfPlainSausages, aNumberOfOnions, anAmountPaid)
        SettotalOfOnions(aNumberOfPlainSausages)
        SettotalOfPlainSausages(aNumberOfOnions)
        SetTotalAmountPaid(anAmountPaid)
        SetTotalAmountDue(GetAmountDue())
        SetTotalChangeDue(GetChangeDue())
        SetTotalSalesTax(SalesTax())
        SetTotalOrderAmount(OrderAmount())
        AssignOrderToOrder(aNumberOfPlainSausages, aNumberOfOnions, anAmountPaid)

    End Sub

    Public Overrides Function ToString() As String

        Return totalOfPlainSausages & " Plain Sausages @ " & FormatCurrency(PLAIN_SAUSAGE_PRICE) & ": " & (totalOfPlainSausages * PLAIN_SAUSAGE_PRICE) & vbNewLine & _

Is there something wrong with the code or are you just trying to make sense of it?

Code works fine. I'm just trying to get the print to work. I'm not entirely sure how to store my programs data in a file or an array and then have it printed.

For that ypu might be better off creating a form with all your data presented how you want it to look and use the printform control.
