The application consists of a text box for specifying the source XML file. The two radio buttons enable you to decide whether ReadXmlSchema() or InferXmlSchema() is to be called. The code for the Read button reads the schema into a DataSet and displays it in a message box. The code that reads the schema is shown in Listing 7-16. Listing 7-16. Using the ReadXmlSchema() and InferXmlSchema() Methods private void button1_Click(object sender, EventArgs e) { DataSet ds = new DataSet(); if (radioButton1.Checked) { ds.ReadXmlSchema(textBox1.Text); } if (radioButton2.Checked) { ds.InferXmlSchema(textBox1.Text,null); } MessageBox.Show(ds.GetXmlSchema()); } The code creates a new DataSet object. Depending on the radio button selected, the code calls either ReadXmlSchema() or InferXmlSchema(). ReadXmlSchema() accepts the source XML document as a parameter and loads the inline schema from the document into the DataSet. No data is loaded. The InferXmlSchema() method accepts the source XML document and an array of namespaces (null in our example) and infers the schema from the data. Again, no data is loaded. The loaded schema is shown in a message box by calling the GetXmlSchema() method of the DataSet. Figure 7-14 shows the schema loaded by using ReadXmlSchema(), whereas Figure 7-15 shows the schema loaded by using InferXmlSchema().

All that remains now is to check that everything is working properly. To do this, use the web interface to place an order and then examine it via the AdminOrders.aspx page. You should see that the order is awaiting confirmation of stock, as shown in Figure 19-3. Click Select and scroll down until the button for confirming stock appears, as shown in Figure 19-4.

Click the Confirm Stock for Order button, and the order will be processed. Because this happens very quickly, you will soon be presented with the next stage, a prompt to confirm shipment. Click the Confirm Order Shipment button, and the order will be completed. If you scroll down further, you can see all audit trail messages that have been stored in the database concerning this order, as shown in Figure 19-5.

How to read and create barcode images using C# and ZXing . NET ...
2 Apr 2016 ... Also, this scanner only reads 1-D barcodes, which hold a small amount of data. 2-D barcodes (sometimes known as QR codes ) are now common, which can hold a lot more data. There's several . NET solutions available to allow us to read barcodes from an image- the one I'm going to look at today is ZXing . NET .

Figure 7-15. Schema extracted by using the InferXmlSchema() method As you can see, the schema loaded by both methods is identical in our example.

Summary

To apply these terms to our example, you will be purchasing a custom domain from Google Apps, GoDaddy, or another domain registrar for an annual fee. In The Perfect Landscape example, the .com domain was used and the domain name the-perfect-landscape.com was purchased and set up to be used with The Perfect Landscape Blogger blog.

While discussing DataSet and DataAdapter, we developed an application that allowed us to perform inserts, updates, and deletes on a DataSet and then save those changes back to the database (see Figure 7-6). In that application, we frequently used collections such as Tables and Rows. We also needed to remember column names while accessing their values from a DataRow. Don t you think it is a bit tedious to access data in this fashion To make things clearer, have a look at Listings 7-17 and 7-18.

You ve taken giant strides toward completing your e-commerce application in this chapter. Now you have a fully audited, secure backbone for the application. Specifically, we ve covered the following: Modifications to the BalloonShop application to enable your own pipeline processing The basic framework for the order pipeline

The database additions for auditing data and storing additional required data in the Orders table The implementation of most of the order pipeline, apart from those sections that deal with credit cards A simple implementation of an order administration web page The only thing missing that needs to be added before you can deliver this application to the outside world is credit card processing functionality, which we ll look at in the next chapter.

Listing 7-17. Inserting a DataRow by Using an Untyped DataSet private void button2_Click(object sender, EventArgs e) { DataRow row = ds.Tables["Employees"].NewRow(); row["employeeid"] = comboBox1.Text; row["firstname"] = textBox1.Text; row["lastname"] = textBox2.Text; row["homephone"] = textBox3.Text; row["notes"] = textBox4.Text; ds.Tables["Employees"].Rows.Add(row); FillEmployees(); } Listing 7-18. Inserting a DataRow by Using a Typed DataSet private void button2_Click(object sender, EventArgs e) { EmployeesDataSet.EmployeesRow row = ds.Employees.NewEmployeesRow(); row.EmployeeID = int.Parse(comboBox1.Text); row.FirstName = textBox1.Text; row.LastName = textBox2.Text; row.HomePhone = textBox3.Text; row.Notes = textBox4.Text; ds.Employees.AddEmployeesRow(row); FillEmployees(); } Both of these listings represent code that inserts a new DataRow into a DataTable. Compare the listings carefully. In Listing 7-17, we access the Employees DataTable and its columns by specifying them in double quotes. That means you need to remember these names when you are coding. However, Listing 7-18 looks different. You will notice that it uses the Employees property to create a new row. Further, it uses column names such as FirstName and LastName as if they are properties. Obviously, the second version is far easier to code and is much neater, which demonstrates what typed DataSets are about. A typed DataSet is nothing but a class that internally derives from DataSet as a base class. It extends this base class further and adds certain properties and methods that make the developer s life easy. When using a typed DataSet, you can access DataTable and DataColumn objects by using strongly typed names instead of the collection syntax. A typed DataSet has an XSD schema attached to it that defines the DataTable and DataColumn objects of the DataSet.
