HELP: Simple POS system in VB .NET

Oct 13th, 2007

I have a assignment from school that I'm having trouble with. I need the program to beable to do... Can someone help me with what I'm doing wrong?

* Input an order ( NumberOfPizzas and NumberOfCokes)
* Compute the OrderAmount = (NumberOfPizzas * decPIZZAPRICE + NumberOfCokes * decCOKEPRICE)
* Compute SalesTax = OrderAmount * decSALESTAXRATE
* Compute AmountDue = OrderAmount + SalesTax
* Display OrderAmount, SalesTax, AmountDue
* Input AmountPaid
* Compute Change = AmountPaid - AmountDue
* Displays Change
* Allows the user to view all the orders placed and a summary of sales for the day (Cokes and Pizzas, total number and $$ amount, and average sale at a minimum.)

Requirements:
Order class
numberOfPizzas
numberOfCokes

methods
InputOrder
GetAmountDue
GetChangedue

DailySummary
private Orders() as Order
numberOfCokes
numberOfPizzas
totalOfCokes
totalOfPizzas

methods
StoreOrder
GetOrder

Figure 1. Mid-Term UML Class diagram

1. Implement the UML class diagram in figure 1 (25 pts)(Note that you can use an arraylist of Order objects in your DailySummary class to make things simpler)
2. (25 pts) Create an order class and instantiate it for each order placed. The order class should have the following methods (at a minimum, you may decide you need more):
* inputOrder (numberOfPizzas, numberOfCokes)
* getAmountDue (which might use private methods to compute orderAmount & salesTax)
* getChangeDue

3. (25 pts) Create a DailySummary class that stores each order and calculates summary information for the day. Store each order object created in an attribute of the DailySummary class. (hint: use a private arraylist in the DailySummary Class to store your orders. Create accessor methods to store and retrieve order info. Create class variables and methods as needed to retrieve order summary data.

4. Design a form (or forms) with the necessary text boxes and buttons to perform the task.

5. Provide some means by which a user can view a summary of the days orders (which will access your DailySummary class)
6. Use a multi-line textbox for all output. Use appropriate formatting for output. Your output should be very similar to (though not necessarily identical):

4 Pizzas @ 8.99: $35.96
5 Cokes @ .99: $4.95
Order Amount: $40.91
Sales Tax: $2.66
Amount Due: $43.57
Amount Paid: $50.00
Change Due: $6.43

My code...

Re: HELP: Simple POS system in VB .NET

Oct 14th, 2007

I didn't get any errors. I just can't seem to get the arraylist to keep the history of all the individual orders so I can print a end of day summary receipt.

 VB.NET Syntax (Toggle Plain Text) 
Private Sub btnPlcOrder_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPlcOrder.Click
 
        custNumOfPizzas = txtPizza.Text
        custNumOfCokes = txtCoke.Text
        custAmtPaid = txtAmtPaid.Text
 
        Dim order1 As New Order(custNumOfPizzas, custNumOfCokes, custAmtPaid)
 
        Dim dailySummary As New DailySummary(custNumOfPizzas, custNumOfCokes, custAmtPaid)
 
        dailySummary.StoreOrder(order1)
 
        txtOutput.Text = dailySummary.ToString
 
        txtReceipt.Text = order1.ToString
 
        ClearForm()
 
    End Sub
Private Sub btnPlcOrder_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPlcOrder.Click

        custNumOfPizzas = txtPizza.Text
        custNumOfCokes = txtCoke.Text
        custAmtPaid = txtAmtPaid.Text

        Dim order1 As New Order(custNumOfPizzas, custNumOfCokes, custAmtPaid)

        Dim dailySummary As New DailySummary(custNumOfPizzas, custNumOfCokes, custAmtPaid)

        dailySummary.StoreOrder(order1)

        txtOutput.Text = dailySummary.ToString

        txtReceipt.Text = order1.ToString

        ClearForm()

    End Sub

i am not sure if this is your peorblem , but should not you declear dailySummary outside
btnPlcOrder_Click code ??
what i understand that each time you place order a new instance of daily summary will creat , where you need only one where you will store all the orders for the day .

"give only what u willing to receive "
