Design - Company --> Customer --> Orders (ignore The Details Of How The Orders Have Products Etc)
Mar 9, 2009
I have a scenario at hand which has some design discussion going on. To break it down in simple words, think about a hierarchy as such Company -----> Customer ------> Orders (ignore the details of how the orders have products etc) if I was to expose an API to work with this, what would be a better design.
a)
Dim comp As New Company
comp.GetInfo(123)
Dim cust As New Customer
cust.Name= "CustomerName"
comp.Add( cust)
b)
Dim custhand As Customerhandler
Dim cust As New Customer
cust.Name= "CustomerName"
custhand.AddCustomer(cust,123) ''123 is CompanyID

I've got 6 hours left to finish a uni project. It's a basic database driven e-commerce site. I have a home page, a products page, an orders page, an order confirm page, a shopping cart page and a view current orders page. The site uses an Access database with three tables. A Customer table, with all of the customer details, (FirstName, LastName, EmailAdd, CardNo, CardEx, SortCode, DeliveryAdd, Postcode) A Products table, with all the product information, (ProductID, ProductName, Price, ProductType, Images, ProductDescription). And an Orders table which contains CustomerID and ProductID. I'm trying to create an INSERT statement on the orders page so that when the customer inserts their details and presses the submit button the customers table will have a new record inserted. I also want this to create an entry in the orders table and redirect the client to the order confirm page which will display the details of the order. Here is my code which runs when the submit button is clicked on the order form. EDIT I've fixed the error with the missing apostrophe. Attempting to insert using two sql commands as I've been told that access databases can't handle two at once. Still getting an error though.
Protected Sub btnAddRecord_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim strFirstName As String

I have the following problem: I select a customer from a dropdownlist and then the gridview should load all items of all orders of that customer. I have the following query:
Dim allorders = From ord In db.Orders
Where ord.CustomerID = Convert.ToInt32(CustomerDropDownList.SelectedValue)
[CODE]..............
I also tried to modify the query as follows:
Dim orderitems = From oi In db.OrderItems
Where oi.OrderNumber = (From From ord In db.Orders
[CODE]...........
But this does not work. I just started using LINQ.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
[code]...
This returns this error "Syntax error in FROM clause." I'm guessing my SQL code is wrong. I noticed when I placed the order in the order page it added an entry in the Access database where the generated CustomerID was 12 on the customers table and 4 in the orders table. Shouldn't these numbers be the same when they are generated?

I am working on an invoicing program that based on the Northwind database.I am pulling information from a 'view' for the orders form.How do i program the customer ID field to populate with the corresponding invoiceID (already done through the view) AND when i drop down the customerID box to list all possible customers from the customers table.I have the SQL for the operation I believe the problem is that the field is bound to the orders Orders Qry 'View'.How can i accomplish both of these tasks within the same dropdown?

So I have a program that is supposed to support a small business. I have the work completed and the professor said it was correct but I wanted to go do a little extra. Basically, on the Order screen, you begin to type the name of a customer/supplier/employee into a text box and a list of names that fit the criteria pops up in a list box (lbMatchingAccounts). When you select it, you can hit enter new order and be transported to the Order Details screen to enter the new order.

I need to make an application that can calculate the items the user chooses from. There is 7 different items the user can choose from.
Small Coffee ..... $4.95
Medium Coffee .... $6.87
Large Coffee ..... $8.52
Bagel ............ $2.99
Cream ............ $0.71
Sugar ............ $0.50
Lid .............. $0.99
Total the coffee order (subtotal + tax at 6% = grand total). Allow the user to delete items from the customer order and to allow the user to start the order for a new customer (clear all). Create a button that gives a 10% discount for coffee only and adjusts the subtotal, tax, and total. Make certain the user can not click the button more than once per customer and if an item is removed from the customer order, make sure the discounted price is removed rather than the list price of the coffee. The button can only be clicked after the coffee is ordered, not before the coffee is selected.
This is what I got so far
Public Class Form1
Private myCoolCheckBoxPrices() As Double = {4.95, 6.87, 8.52, 2.99, 0.71, 0.5, 0.99}
Private myTax As Double = 0.06 'Tax used to add to Total Price
Private Sub lstItems_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstItems.DoubleClick

I am using the northwind database, My goal is to create an application that has a main form area for the orders and a details section (I guess a data grid view)How can I Utilize the data grid view for inputting values such as Product, Quantity, Unit Price, Extended price.... Specifically how to program the date grid view to multiply unit price by Quantity to get the extended price, then add up all the extended prices and shove that to another txtBox outside the dataGridView (txtSubtotal)Saving the header (to the Orders table) and using the InvoiceID to also save the details section in the OrdersDetail table.

This program I am writing is basically a way to record orders. So I got a bunch of possible components required, which got their textfield(1 for product info, 1 for product price). Those are controlled with a checkbox, disabled on default. Enabled when checked.
Something like this:
Label, Checkbox, Product info textbox, Product price textbox.
This for a bunch of products, and at the bottom you got the total costs textbox.
Which updates as entries are made.
1. Would a access database be a good thing to use for this? To save the completed forms to, for later viewing through the program. Or are the better options for this kind of thing.
2. Would crystal reports be a good choice to make the reports after the form has being completed. So you got a decent sheet which shows you the entire order, and give a print ability.

I have written a small program to allow our employees to submit work orders. I want to have each computer on our network to be able to open the program, run it, and have the files (which are actually jpeg's of the form) saved on the server. This part works fine.
I have it loaded on the server and have tried to run it from several computers. While the program does run ok, it does not load the My.Settings items that are on the server. On each computer the program has, or appears to have its own set of my.settings.
If I go to the form in the program that allows me to add items to my.settings, and make changes they are saved, but when I go to the next computer they are not there. It only reflects the my.settings that were put directly in during program construction. (opened my.setting, clicked on the setting and added them there)
My question is,, how to get the program to stay on the server when running it so that the settings are there no matter which pc is running it? This is a windows forms program, I am using Visual Basic 2010 Express.

I need to read signed and unsigned 8 bit, 16 bit and 32 bit values from a file stream which may be little-endian or big-endian (it happens to be a tiff file which carries the byte order indicator at the start).I initially started by writing my own functions to read the values and was able to do so for unsigned values. e.g.
Public Function ReadUInt32() As UInt32
Dim b(4) As Byte
input.Read(b, 0, 4)
[code]....
But then I started looking at signed values and my brain broke.As an alternative, I found the IO.BinaryReader which will let me read signed values directly but doesn't seem to have any way to indicate that the data is big-endian or little-endian.Is there a nice way of handling this? Failing that, can someone tell me how to convert multiple bytes into signed values (in both byte orders)?

I'm trying to generate a report that shows the products ordered for a given customer.
I'm getting an error on the line that states:
lblList.Text &= rowInvoices(
"ProductCode")
& " "
& rowInvoices("Quantity")
The error message states: Column 'ProductCode' does not belong to table Customers.
I have three tables: The Customer Table, which points to the Invoice Invoice table via the CustomerID.
Also, the Invoice table, which contains the product code, points to the Invoice table via the InvoiceID.
If possible I'd like to bring in the Products table to get the Product description.

I want to "manage" a table of "orders." Orders is a typical table with a foreign key pointing to a customer, and a one-to-many relationship with a "details" table. To manage orders means to enter new orders, add details to orders, record payments, print a list of orders, cancel orders, mark orders shipped, print one order, etc., etc. These tasks can be divided into tasks that affect single orders (cancel an order) and tasks that affect multiple orders (print a list of orders).That task division led me to this user interface: present a form/window that displays by default a list of orders, and provide a button that switches the view from list mode to single-order mode. Each mode then provides the buttons for its tasks.

I'm redesigning an old VB6 application into VB.net and there is one thing I'm not sure on the best way to do. In the VB6 application whenever we created a new instance of a component, we would pass in the user details (user name and the like) so we new who was performing the tasks. However, no that I'm redesigning I've created some nice class designs, but I'm having to add in user details into every class and it just looks wrong.
Is there a VB.net way of doing this so my classes can just have class specific details? Some way so that if my classes need to know who is performing a task, they can get the information themselves, rather than having it passed in whenever the objects are created?
