Though XSLT offers a few programming constructions and built-in functions, it is not a fully fledged programming language in itself. Sometimes, you may need to perform an operation that is beyond the capabilities of XSLT. For example, you may want to connect with a SQL Server database and fetch some data that is used further by the style sheet, or you may need to perform disk IO. To cater to such needs, XslCompiledTransform allows you to embed scripts within your XSLT style sheets. After the style sheet is loaded, the embedded code is compiled into Microsoft Intermediate Language (MSIL) and executed at run time. free qr code reader for .net zxing/zxing: ZXing ("Zebra Crossing") barcode scanning ... - GitHub

To support portals that do not have this mode, you can add a navigation link to the appropriate screens of your portlet that will provide your users with the same functionality but in the VIEW portlet mode. You could remove this link inside portals that support a graphical user interface (GUI) mechanism for switching to this portlet mode. For more on portlet modes, see 4. qr code reader c# .net QrCode .

Our Employees.xml file stores a subset of information from the Employees table of the Northwind database; it represents only four fields of the actual table: firstname, lastname, homephone, and notes. Let s assume that for some reason you also need the extract the date of birth of each employee at run time. That means we need to write some ADO.NET code to retrieve the BirthDate column value from the database table. We will do this by embedding a script block in the style sheet. Listing 6-14 shows the complete style sheet. Listing 6-14.

The <xsl:stylesheet> element now has two more attributes. The xmlns:msxsl attribute defines the msxml prefix for the urn:schemas-microsoft-com:xslt namespace. Similarly, the xmlns:myscripts attribute defines a myscripts prefix. The <msxml:script> block defines one or more functions that are used in the style sheet. The language attribute of the script block indicates the coding language (C# in our example). Your code may need to add a reference to external assemblies, which is done by using the <msxsl:assembly> element. The name attribute of this tag specifies the name of the assembly, excluding the extension. Similarly, the <msxml:using> tag specifies the namespaces to be imported. The actual function is placed in a CDATA section. In our example, we defined a function called GetBirthDate() that accepts the ID of the employee whose date of birth is to be retrieved and returns the birth date in MM/dd/yyyy format. The code of the function connects with the Northwind database, fires a SELECT query against the employees table, and retrieves the birth date. public String getPortalInfo() validCredentials: true for successful login, false for bad credentials userContext: Context data that was passed to the service in its UserContext property methodName: Name of the method that triggered the callback (usually Sys.Services.AuthenticationService.login) net qr code reader open source VB .
