Expiration date set Test validates that relatively static content has an expiration date greater than today. Round trip analysis Evaluates number of round trips for any request and identifies ways to reduce them. Most of these metrics come from design best practices. The great thing about a best practice is that there is quite often a test needed to verify that it was applied optimally. Certainly, many other metrics are unique to services and some are unique to specific types of services. For example, in the search space one of the most critical measurements is relevance. This is a measure of how likely the content of a Web page will meet the user's needs based upon the search criteria. In this section, I pared the list of potential metrics down to a small subset focused on performance. These metrics are common to any online service. I also picked metrics that reference good-quality freely available test tools to use in running the tests: Visual Round Trip Analyzer (VRTA) will be available on the Microsoft Developer Network (http://msdn.microsoft.com) by the time this book is published. Fiddler is already available at http://www.fiddler2.com and there are a number of articles about it posted on MSDN. vb.net read pdf into byte array: C# / VB .

NET Framework, only three classes support XPath navigators: XmlDocument, XPathDocument, and XmlDataDocument An XPath navigator works on top of a special breed of XML document class that is generically referred to as an XPath data store An XPath data store is simply any NET Framework class that exposes its contents as XML and that can be queried using XPath expressions An XPath data store can be based on a native XML stream or other data sources exposed as XML For example, both the XmlDocument and XPathDocument classes are built from well-formed XML data In contrast, the XmlDataDocument class exposes as XML the contents of an ADONET DataSet object In all cases, however, the XPath query and navigation API works just fine As a stand-alone class providing a programming interface, the navigator is much more than a simple collection of XPath-related methods. vb.net print pdf to specific printer: vb.net code, print pdf file to a non-default printer. - Experts Exchange vb.net read pdf file Reading PDF content with itextsharp dll in VB .

The XPath navigator is not bound to a particular class document and can be associated with a number of data container classes A NET Framework class becomes XPath-enabled simply by implementing the IXPathNavigable interface This interface consists of a single method, CreateNavigator, that creates and returns an instance of a document-specific navigator object, as shown here: public interface IXPathNavigable { XPathNavigator CreateNavigator(); } All document-specific navigators derive from the XPathNavigator abstract class XPath Navigators and XML Readers The MSDN documentation defines an XPath navigator as a class that reads data from an XML-based data store using a cursor model XPathNavigator, therefore, provides read-only, random access to the underlying XML-based data The navigator has a notion of the current node and advances the internal pointer using a series of move methods When the navigator is positioned on a given node, all of its properties reflect the value of that node. Page Load Time 1 (PLT1) and Page Load Time 2 (PLT2) are the key measures for user satisfaction. Research has shown that Web pages that take longer than just a few seconds to load rate lower than a similar page that loads much quicker. Some search engines even use PLT measurements in weighting of search results. A slower page will fall farther down in the list of returned pages even if the content is as good a match as another faster page. In Microsoft, we focus heavily on measuring our own services' PLTs as well as those of our competition. This analysis is done for PLT1 and PLT2 but also by country, as shown in Figure 14-9. const char * szFile const char * szModule const char * szFormat ... { // Just say no to reentrant code! EnterCriticalSection ( &g_csRTCLock ) ; How is this different from the XML readers that we encountered in 2 XPath navigators and XML readers are radically different objects, although both look like client-side cursors for reading XML data Let's review the key differences: 218. PLT for a country is often affected by the bandwidth to the country and the distance the data must travel to reach the user. Network engineers are fond of saying that they are limited by the speed of light. // Get the two variable length parameters. I guess they plan on // adding a ton of these RTC checks in the future. va_list vl ; va_start ( vl , szFormat ) ; // The first one is the number of the error that occured. _RTC_ErrorNumber RTCErrNum = va_arg ( vl , _RTC_ErrorNumber ) ; // The second is the additional description of the error. char * szErrorVariableDesc = va_arg ( vl , char * ) ; va_end ( vl ) ; 659 TCHAR szBuff [ 512 ] ; // Get the error description text based off the error number. const char *szErr = _RTC_GetErrDesc ( RTCErrNum ) ; // Make sure szFile and szModule have something in them. if ( NULL == szFile ) { szFile = "Unknown File" ; } if ( NULL == szModule ) { szModule = "Unknown Module" ; } // If it's any error other than /RTCc, I can show some cool info // that includes the variable in question! if ( 1 != RTCErrNum ) { _stprintf ( szBuff szErr szErrorVariableDesc iLine szFile szModule ) ; } else { // Build the string. _stprintf ( szBuff szErr iLine szFile szModule } , , , , ) ; _T ( "%S\nLine #%d\nFile:%S\nModule:%S" ) , , , , , , _T ( "%S\n%S\nLine #%d\nFile:%S\nModule:%S" ) , Connection model Both readers and navigators work on top of a data source Readers, however, work connected to the input stream, which is often a persistent storage medium like a disk file Navigators always work on memory-mapped data sources like XML DOM or more optimized and specialized structures Readers must be closed when you have finished with them; navigators are simply garbage-collected when they go out of scope A parallel can be drawn with ADONET data readers and DataSet objects An XML data reader object, like the SqlDataReader base class, is connected to the data source, whereas a DataSet object is a disconnected object Navigation interface Readers are simple read-only and forward-only cursors Navigators too are read-only, but they let you move forward and backward The navigator's set of move methods is significantly richer. Figure 14-9: Analysis of two user transactions, login and view file, for Microsoft service versus a competitor. In most cases, except for China, Microsoft is slower. In some respects, it's like watching one of those cable news channels when the field reporter is halfway around the world and the anchor is asking a question. The field reporter stands there nodding as the question is asked. When the anchor is done asking, we all see the reporter continue to nod for another second before starting to answer. In the same way, data sent from a server to a browser is limited by the speed of light. Network impact on PLT is just one element. The biggest improvements to PLT can be made through various optimization techniques. The rest of the metrics covered in this section are ones that we use to improve the quality of the code and content for optimized page load times. int iRes = TRUE ; if ( IDYES == MessageBox ( GetForegroundWindow ( ) szBuff _T ( "Run Time Check Failure" ) MB_YESNO | MB_ICONQUESTION ) { // Returning 1 means DebugBreak will happen when this // function returns. iRes = 1 ; } else { iRes = 0 ; } // Pop out of the lock.
