I have an assignement to use each grouping of code only once and put it into an application. Cut the snips of code from the snips part (ill have that coded at the bottom) and paste in the application based on comments within the application. You dont enter a single character of code. The teacher made sure the application has been verified and does work. The problem is I keep running into the same problem, I have more code then places to put them, so im hoping you guys could see where im leaving the codes out, basically all im asking is could you look at the code and see where everything goes and could help me out. I know where certain things go like

If intProductsEntered

and where the close goes, but I always got a couple left, ill leave everything blank so you can see it the way I got it, where it has the ' and then writing right under that, thats where the code should go There is 4 forms of codes on here. Form1 code is

Public Class frmOrderTotal

    Public Sub LoadOrder()
        'clear the grid
        dgOrder.Rows.Clear()
        Dim dclOrderTotal As Decimal
        'add all products to screen by adding rows to data grid
        For i As Integer = 0 To Products.Length - 1
            dgOrder.Rows.Add()
            dgOrder.Rows(i).Cells(0).Value = Products(i).UPC
            dgOrder.Rows(i).Cells(1).Value = Products(i).Description
            dgOrder.Rows(i).Cells(2).Value = FormatCurrency(Products(i).Price)
            dgOrder.Rows(i).Cells(3).Value = Products(i).Qty
            'display extended price to screen
            dgOrder.Rows(i).Cells(4).Value = FormatCurrency(Products(i).Qty * Products(i).Price)
            'accumulate total price

        Next
        'display total price
        lblOrderTotal.Text = FormatCurrency(dclOrderTotal)

Now I keep putting code in here and trying to figure out everything but I still keep coming up with problems of putting it in the right place, you cant edit the code in any way except for copy and past the snips into the right place, but this is where im having trouble at, because like I said I keep running into more code snips then where to put them, all the code has to used, so its not like its a trick or anything, im just having trouble doing this and was hoping you guys could help me out, ill figure it would be an easy solved thread and could help people out that are having the same trouble as me, I know its a bad thing to have people do my assignmaets for me but I dont know what to do, and its not like people are making any code for me all im asking is can someone help me put the snips in the right place and thats all, thanks

Im just having problem trying to figure out wher to put

For i As Integer = 0 To Products.Length – 1
      Products(i).Qty = 0
 Next

and

Dim textfile As StreamWriter
textfile = File.CreateText(FileName(OrderDate))
For i As Integer = 0 To Products.Length – 1
     If Products(i).Qty > 0 Then
          textfile.WriteLine(Products(i).UPC)
          textfile.WriteLine(Products(i).Qty)
    End If
Next
textfile.Close()

because it keeps on coming up with an error with the " - " thats after the product length, these are the only two i need help on figuring out where they go

Hi,

You can try this:

Dim i As Integer
 For i = 0 To Products.Length – 1
      Products(i).Qty = 0
 Next

And:

Dim textfile As StreamWriter
textfile = File.CreateText(FileName(OrderDate))
Dim i As Integer
For i = 0 To Products.Length – 1
     If Products(i).Qty > 0 Then
          textfile.WriteLine(Products(i).UPC)
          textfile.WriteLine(Products(i).Qty)
    End If
Next
textfile.Close()
