methods described in Table 29-5 to change the content. Listing 29-14 provides a demonstration of changing the name of an element, using the same source XML as Listing 29-13. Listing 29-14. Changing the Name of an Element using System; using System.Collections.Generic; using System.Xml.Linq; class Listing 14 { static void Main(string[] args) { // load the XML data XElement rootNode = XElement.Load(@"..\..\data.xml"); // get all of the nodes called StockLevel anywhere in the XML IEnumerable<XElement> stockElements = rootNode.Descendants("StockLevel"); // enumerate the elements and change the name of each foreach (XElement elem in stockElements) { elem.Name = "ItemCount"; } // print out the XML to the Console Console.WriteLine(rootNode); // wait for input before exiting Console.WriteLine("Press enter to finish"); Console.ReadLine(); } } I use the Descendants method to obtain an enumeration of all the elements with the name StockLevel and then assign a new value to the Name property. This has the effect of changing the name of these elements, as the following output demonstrates: <Fruits> <Fruit> <Name>Cherry</Name> <Color>Red</Color> <ItemCount>500</ItemCount> </Fruit> <Fruit> <Name>Apple</Name> <Color>Green</Color> <ItemCount>230</ItemCount> </Fruit> <Fruit> <Name>Plum</Name> <Color>Red</Color> .net ean 13 EAN13 Barcode Control - CodeProject

And according to GS1 General Specification, EAN13 can encode 12 data and 1 check digit. As for the check digit, our VB . NET Barcode Generator Component could generate it automatically. How to Generate EAN - 13 Barcodes in VB . NET Class? You can use the System.Xml.Linq namespace classes on their own. These classes can stand on their own, and there are no additional features that come from using these classes with LINQ queries. But to use these classes without LINQ queries is to miss out on the flexibility and simplicity that combining them can bring. In the following sections, I ll show you some different techniques for using queries on XML data. All of these examples could be achieved without the query, but the code required would be more verbose and more error-prone. Most of the examples in this section use the following XML file: < xml version="1.0" encoding="utf-8" > <Fruits> <Fruit> <Name>Cherry</Name> <Color>Red</Color> <StockLevel>500</StockLevel> </Fruit> <Fruit> <Name>Apple</Name> <Color>Green</Color> <StockLevel>230</StockLevel> </Fruit> <Fruit> <Name>Plum</Name> <Color>Red</Color> <StockLevel>300</StockLevel> </Fruit> <Fruit> <Name>Banana</Name> <Color>Yellow</Color> <StockLevel>100</StockLevel> </Fruit> <Fruit> <Name>Grape</Name> <Color>Green</Color> <StockLevel>400</StockLevel> </Fruit> </Fruits> This file is included in the Visual Studio projects as data.xml and loaded at the start of each example that uses it. vb.net ean-13 barcode EAN - 13 VB .

EAN13 ASP . NET Barcode Generation Guide illustrates how to create EAN13 barcode in ASP . NET web application/web site / IIS using in C# or VB programming. class Listing 15 { static void Main(string[] args) { // load the XML data XElement rootNode = XElement.Load(@"..\..\data.xml"); // perform a query on the XML var results = from fruit in rootNode.Elements() let stockLevel = int.Parse(fruit.Element("StockLevel").Value) where stockLevel < 250 select new { Name = fruit.Element("Name").Value, Count = stockLevel }; // write out the results Console.WriteLine("Fruits that are low on stock:"); foreach (var item in results) { Console.WriteLine("Name: {0}, Current Stock: {1}", item.Name, item.Count); } // wait for input before exiting Console.WriteLine("Press enter to finish"); Console.ReadLine(); } } This query enumerates the elements that are immediate descendants of the root node. An int range variable is defined using the let keyword and assigned the value of parsing the Value property of the StockLevel element. A where clause filters for items that have a low stock level, and the select clause projects an anonymous type containing the Value property of the first-level element and the value of the int range variable. With a simple query, we have created a stock reorder report. Compiling and running Listing 29-15 produces the following results: Fruits that are low on stock: Name: Apple, Current Stock: 230 /** * This object contains factory methods for each * Java content interface and Java element interface * generated in the net.jzventures package. * <p>An ObjectFactory allows you to programatically * construct new instances of the Java representation * for XML content.
