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(). java upc-a Generate UPC-A barcode in Java class using Java UPC-A ...

If your PC is already connected to the Internet, Ubuntu may already have detected your location correctly. You can select your time zone manually by clicking your location on the world map that s displayed or by selecting the nearest city from the dropdown lists at the base of the page. When you click the map, you ll see that the time zone is highlighted in green, and you can click near your location within this band. You ll also see a live clock showing the time in that location. See Figure 4-3 for an example. s Testing whether a connection is open before attempting to close it isn t actually necessary. The Tip Figure 4-3. Select the time zone from the map and then you can refine your options by using the dropdown lists at the bottom of the page. The city you choose doesn t matter a great deal the purpose of this step is to ensure that Ubuntu selects the correct time zone for your location, which it does by looking up the city in a database of time zones. After you ve made your selection, click the Forward button. 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. java upc-a BE THE CODER > Barcodes > Barcode4j Examples > Barcode UPC-A
