This XmlReader in this example works in the same way as the XmlTextReader you ve been using up until now, but it adds the ability to verify that the XML document follows the schema rules. This reader throws an exception (or raises an event) to indicate errors as you move through the XML file. The following example shows how you can create an XmlValidatingReader that uses the SuperProProductList.xsd file to verify that the XML in SuperProProductList.xml is valid:

' Set the validation settings. Dim settings As New XmlReaderSettings() settings.Schemas.Add("http://www.SuperProProducts.com/SuperProProductList", _ Request.PhysicalApplicationPath & "\SuperProProductList.xsd") settings.ValidationType = ValidationType.Schema ' Open the XML file. Dim fs As New FileStream(filePath, FileMode.Open) ' Create the validating reader. Dim r As XmlReader = XmlReader.Create(fs, settings) ' Read through the document. Do While r.Read() ' Process document here. ' If an error is found, an exception will be thrown. Loop r.Close()

And, of course, you can click the notification to view the message in the full-fledged messaging application, as shown in Figure 35 16.

Using the current file, this code will succeed, and you ll be able to access the current node through the XmlValidatingReader object in the same way you could with the XmlTextReader. However, consider what happens if you make the minor modification shown here:

Multiplicity refers to the numbers that you often see on the lines between classes on class diagrams. For example, Figure 8-15 shows an excerpt from a class diagram showing multiplicity, and Figure 8-16 shows how the same diagram might be described in text form.

Now when you try to validate the document, an XmlSchemaException (from the System.Xml.Schema namespace) will be thrown, alerting you to the invalid data type, as shown in Figure 17-7.

Instead of catching errors, you can react to the XmlReaderSettings. ValidationEventHandler event. If you react to this event, you ll be provided with information about the error, but no exception will be thrown. To connect an event handler to this event, you can use the AddHandler statement before you read the XML content:

Create PDF Thumbnail C# in WinForms - Stack Overflow
Take a look at PDFLibNet. It is a single DLL that you can use to view PDFs. You can use it to generate preview images for each page like this:

The T-Mobile G1 has a microSD card slot. Many other Android devices are likely to have similar forms of removable storage, which the Android platform refers to generically as an SD card. It s strongly recommended that developers use SD cards as the holding pen for large data sets: images, movie clips, audio files, and so on. The T-Mobile G1, in particular, has a relatively paltry amount of on-board flash memory, so the more you can store on an SD card, the better. Of course, the challenge is that, while the G1 has an SD card by default, the emulator does not. To make the emulator work like the G1, you need to create and insert an SD card into the emulator.

The event handler receives a ValidationEventArgs object as a parameter, which contains the exception, a message, and a number representing the severity:

Private Sub ValidateHandler(ByVal sender As Object, ByVal e As ValidationEventArgs) lblStatus.Text &= "Error: " & e.Message & "<br />" End Sub

To test the validation, you can use the XmlValidation.aspx page in the online samples. It allows you to validate a valid SuperProProductList, as well as two other versions, one with incorrect data and one with an incorrect element (see Figure 17-8).
