Northwind Smart Client Sample
This sample runs only in Microsoft Office Excel 2007 and Microsoft Office Word 2007.
This sample uses document-level customizations for Excel and Word to implement an order tracking system based on the Northwind sample database for Microsoft SQL Server. The sample includes the following features:
Northwind Catalog template. This Excel template is used by customers to browse the different product offerings of the Northwind Supply Company. The template retrieves product information from the SQL Server Northwind database by calling the Northwind Web service. Using this template, customers can purchase different products, view and update their orders, and complete their orders with shipping information. The workbook retains information about the order between uses to enable the customer to use the catalog offline.
The template does not retrieve orders that have already been submitted; it only creates and edits new orders.
Northwind Web service. After customers complete their orders they click Checkout, which submits the order to the Northwind Web service. The Web service adds the order information to the Northwind Order Rollup workbook and returns an Order ID.
Northwind Order Rollup workbook. This Excel workbook provides a consolidated view of all the new orders that are submitted through the Northwind Catalog and Northwind Web service. Users can track the company's order history to see which products are being purchased, who is purchasing them, how often they are purchased, and how much is purchased.
Northwind Web site. Users can view a list of all orders that have been submitted to the Northwind Web service from an ASPX page. This page reads data from the Northwind Order Rollup workbook. Users can select an order and click the Create Invoice button to write the data for that order into a new document made from the Northwind Invoice template. They can also view invoices that have already been created by clicking View Invoice.
Northwind Invoice template. This Word template is used by employees of the Northwind Supply Company to create invoices for customers. When an employee opens the template, the invoice for the data is created if data has already been added to the data cache by the Northwind Web site. If there is no data in the data cache, a Windows Form is displayed and the user can select which customer and which order to create the invoice for. The Northwind Invoice template then creates an invoice from data in the Northwind Order Rollup workbook.
