However, an important piece is added at the top (see the markup shown in bold). We have added a DTD for our document. I will not go into the details of the DTD here, but suffice it to say that the ATTLIST section defines an attribute called employeeid for the <employee> element. More important, the employeeid attribute is marked as the ID and is also a REQUIRED attribute. This is how the XmlDocument class knows which attribute of an element is acting as an ID. If you look at the source code of the application, you will see a form-level variable of type XmlDocument called doc: XmlDocument doc = new XmlDocument(); The Load event handler of the form bears the code shown in Listing 2-7. Listing 2-7. Populating the Combo Box private void Form1_Load(object sender, EventArgs e) { doc.Load(Application.StartupPath + "/employees.xml"); foreach (XmlNode node in doc.DocumentElement.ChildNodes) { string employeeid = node.Attributes["employeeid"].Value; comboBox1.Items.Add(employeeid); } } code 128 algorithm c# Code 128 C# .NET Barcode Generator - Create Code 128 Barcode ...

Keepdynamic.com offers Code 128 C# .NET Barcode Generator for the generation of Code 128 barcodes, an alphanumeric barcodes with high-density data ... The code loads the new Employees.xml file in the XmlDocument instance we created earlier by using its Load() method. A foreach loop then iterates over all the <employee> nodes. With each iteration, the employeeid attribute of the <employee> node is retrieved using the Attributes collection of the XmlNode class. The attribute value is added to the combo box. When the user selects a particular ID, the details of that employee are displayed. This is accomplished in the Click event handler of the Show Details button. The code inside the Click event handler is shown in Listing 2-8. Listing 2-8. Calling the GetElementById() Method private void button1_Click(object sender, EventArgs e) { XmlElement ele= doc.GetElementById(comboBox1.SelectedItem.ToString()); label6.Text = ele.ChildNodes[0].InnerText; label7.Text = ele.ChildNodes[1].InnerText; label8.Text = ele.ChildNodes[2].InnerText; label9.Text = ele.ChildNodes[3].InnerText; } The code calls the GetElementById() method of the XmlDocument class and passes the employee ID to look for. The GetElementById() method returns the matching element as an object of type XmlElement. Because the XmlElement class inherits from the XmlNode class, the ChildNodes collection is available to the XmlElement class also. To retrieve the values of the <firstname>, <lastname>, <homephone>, and <notes> nodes, the ChildNodes collection is accessed by using the index of the corresponding element. Finally, the InnerText property of each XmlNode gives the text inside the appropriate node. c# code 128 source Free Barcode 128 library for C# - Stack Overflow

You ll be using the same DataSet here as you used in that chapter when you created a web service. The first thing you ll need to do is create the interface that defines your service contract. In the 5 web service, you passed an XmlDocument type, which is a complex object requiring some pretty sophisticated data contracts to be set up in order to use it. For the sake of simplicity in this example, you ll instead pass a string. As a string is a simple data type, you don t need to define a data contract for it. However, you ll still need the ServiceContract to define the interface, and an OperationContract to define the methods that are consumable by a client. Here s the code: The item caused a problem, so let s remove it from the queue: string GetAttribute(int i); string GetAttribute(string name, string namespaceURI); string GetAttribute(string name); bool HasValue [ServiceContract()] public interface IAddressService { [OperationContract] string GetAddresses(string strZIP); } links.remove(link); failed.add(link); } finally { string LookupNamespace(string prefix); bool MoveToAttribute(string name, string ns); bool MoveToAttribute(string name); bool MoveToElement(); bool MoveToFirstAttribute(); bool MoveToNextAttribute(); XmlNameTable NameTable Next, you build your class that implements this interface. This class will also implement the specified operation (GetAddresses). First, here s the class description: To ensure that the connection is closed correctly, we use the following: if( connection != null ) { connection.disconnect(); } } } public class AddressService : IAddressService { } public { get; } public { get; } public { get; } public public public { get; } public public { get; } c# code 128 string How to Generate Code 128 Using C# .NET Barcode Generator
