A Better Way to Select a Single Node In the section "The SelectSingleNode Internal Implementation," on page 255, I pointed out that SelectSingleNode is not as efficient as its signature and description might suggest. This XML DOM method is expected to perform an XPath query and then return only the first node. You might think that the method works smartly, returning to the caller as soon as the first node has been found. Unfortunately, that isn't what happens. SelectSingleNode internally calls SelectNodes, downloads all the nodes (potentially a large number), and then returns only the first node to the caller. The inefficiency of this implementation lies in the fact that a significant memory footprint might be required, albeit for a very short time. So in situations in which you need to perform an XPath query to get only a subset of the final node-set (for example, exactly one node), you can use a smarter XPath expression. The basic idea is that you avoid generic wildcard expressions like the following: doc.SelectSingleNode("NorthwindEmployees/Employee"); Instead, place a stronger filter on the XPath expression so that it returns just the subset you want. For example, to get only the first node, use the following query: doc.SelectSingleNode("NorthwindEmployees/Employee[position() = 1"); The same pattern can be applied to get a matching node in a particular position. For example, if you need to get the nth matching node, use the following expression: doc.SelectSingleNode("NorthwindEmployees/Employee[position() < n+1"); Using such XPath expressions with SelectSingleNode does not change the internal implementation of the method, but those expressions require downloading a smaller subset of nodes prior to returning the first matching node to the caller. The same XPath expression, if used with SelectNodes, returns a subset of the first n matching nodes: doc.SelectNodes("NorthwindEmployees/Employee[position() < n+1"); vb.net pdf read: Embed PDF into a VB .

The second switch, /RTCu, checks your variable usage and will pop the warning if you use any without initializing them first If you've been a loyal Bugslayer over the years, you might be wondering why this switch is important Since all loyal readers (like you) are already compiling their code with warning level 4 (/W4) and treating all warnings as errors (/WX), you know that compiler warnings C4700 and C4701 will always tell you at compile time where you are definitely using and where you might be using variables without initialization, respectively With the /RTCu switch, those who aren't will still be told they have bugs in their code What's interesting about the /RTCu switch is the code to check for uninitialized variables is inserted if the compiler detects a C4700 or C4701 condition The third switch, /RTC1, is just shorthand for combining /RTCu and /RTCs. vb.net print pdf to default printer: Printing a PDF to a non default printer-VBForums vb.net open pdf file in adobe reader convert a pdf file into byte array and pass it to a service and ...

This library specifically references the ability to fill in PDF forms and should fit the bill for filling in your pre-existing PDF form programatically. We find that the shape of the production data changes over time as the use of certain data elements extends and other elements are forgotten and left as legacy Whether the production data contains any PII or not, it must be sanitized before testing I have seen teams forget to scrub live site end points from their production data and accidently send a flood of test traffic over the Internet against the production site Therefore, the first rule in using production data is to sanitize it Note Data masking, usually referred to as data sanitization in Microsoft, is a process of obscuring specific data within database tables to ensure sensitive production data is not accidently leaked Scrubbing algorithms are used to generate random substitute but fully functional data in place of the original The second key to using production data is to analyze it. The final switch, /RTCc, checks for data truncation assignments for example, if you try to assign 0x101 to a char variable Like the /RTCu, if you're compiling with /W4 and /WX, data truncation will produce a C4244 error at compilation time If you get an /RTCc error, you 656. vb.net pdfreader NET PDF Text Extractor & Converter - Extract Text from PDF C#/ VB ...

The XML DOM support for XPath expressions has a double goal. First, it smooths the transition from MSXML COM code to the .NET Framework. Second, it gives you a builtin and easy-to-use mechanism to search for nodes in a memory-mapped XML document. As mentioned, the core .NET API for processing XPath expressions is built into a tailor-made class named XPathNavigator. You access the navigator object either from the XmlDocument class or from the newest XPathDocument class. Figure 6-5 illustrates the relationship between the two ways of accessing XPath functions in the .NET Framework. have to either mask off the bits you need or cast to the appropriate value. The project Property Pages dialog box, shown in Figure 17-7, allows you to only set /RTCu, /RTCs, or /RTC1 in the Basic Runtime Checks option. In order to turn on /RTCc, you'll need to select the Smaller Type Check option above the Basic Runtime Checks option, as shown in Figure 17-7. Too often teams take the data, sanitize it, and use it for testing By analyzing the data, we can look for boundary conditions If you want to know the longest city name from a dump of personalization data, analyze it and pull that out It could be a valuable piece of information in producing tests that can run without production data Performance Test Metrics for Services Throughout this book, we have discussed many different metrics used to drive quality into Microsoft products All of the metrics covered so far apply to S+S testing Fortunately, this chapter presents new metrics to measure and track for S+S testing, as presented in Table 14-3 Table 14-3: Test Metrics for Browser-Based Services. Figure 6-5: Applications can access XPath through either XmlDocument or XPathDocument. In both cases, the actual query is performed by a .NET XPath navigator object. As you can see, the XmlDocument and XPathDocument classes have different internal layouts. XmlDocument implements XML DOM, whereas XPathDocument provides a more agile and compact structure, designed to speed XPath-driven navigation. (Later in this chapter, in the section "The XPathDocument Class," on page 281, I'll have more to say about this.) No matter the application-level API, the sequence of steps necessary to execute XPath queries on an XML data source is always the same: 1. Get a reference to an XPath-enabled document class (for example, an instance of an XPathDocument or XmlDocument class). 2. Create a navigator object for the class instance. 217 Figure 17-7: Setting the /RTCx switches At first, I couldn't see why the /RTCc switch was not turned on by the /RTC1. A little thinking showed that /RTCc can show errors on legal C code such as the following: char LoByte(int a) { return ((char)a) ; } If /RTCc were included in /RTC1, people might think that all the Run-Time Error Checks switches are reporting false positives. However, I vote for always turning on /RTCc because I want to know about any potential problems whenever I run my code. With the switch descriptions out of the way, I want to turn to the notification you get when you do have an error. When running your programs outside the debugger, the run-time checking code uses the standard C run-time assertion message box. For those of you writing services or code that can't have a user interface, you'll need to redirect the message box using the _CrtSetReportMode function with the _CRT_ASSERT report type parameter. You might think there would be a single, standard way for the /RTCx switches to notify the user, but that's not the case. When running under the debugger, there's a completely different way to do the notifications. If you happen to look at the Exceptions dialog box in the Visual Studio .NET IDE, you might notice several new classes of exceptions added. The interesting new exception class is 657 Native Run-Time Checks. As you look at it in the Exceptions dialog box, you'll recognize the four different exceptions as matching up with the /RTCx switches. That's your hint that when your program encounters a run-time check while running under the debugger, your program will throw a special exception so that the debugger can handle it. Controlling Run-Time Check Output While the default method of output will suffice for many situations, you might want to handle the error output yourself. Listing 17-6 shows a sample custom error handler. The parameter list for run-time check error handlers is a little different in that it takes variable parameters. Evidently, Microsoft is planning to add quite a few different run-time error checks in the future to account for this flexibility. Since your custom handler gets the same parameters as the default version, you can show the errors with variable information and everything else. As you can see from Listing 17-6, it's up to you how you choose to inform the user. The code from Listing 17-6 is with this book's sample files in the RTCHandling sample, so you can play with the error handling all you want. Listing 17-6: /RTCx custom error reporting /*///////////////////////////////////////////////////////////////// //// FUNCTION DESCRIPTION : : HandleRTCFailure Page Load Time 1 Measures the amount of time it takes for a browser to load a new page from the (PLT1) first request to the final bit of data. A new page is any Web page the browser has never been to before and for which it has no content cached. Page Load Time 2 Measures the amount of time it takes for a page to load on every visit after the (PLT2) first. This should always be faster than PLT1 because the browser should have some content cached. Page weight The size of a Web page in bytes. A page consisting of more bytes of data will typically load more slowly than a lighter weight page will. Measures the compression potential of files and images. 3 Optionally, precompile the XPath expression 4 Call the Select method on the navigator object to act on the specified XPath expression The XPathNavigator Class The programming interface of the navigator object is defined in the XPathNavigator abstract class The XPathNavigator class represents a generic interface designed to act as a reader for any data that exposes its contents as XML Functionally speaking, the XPathNavigator class is not much different from a pseudoclass that simply groups together all the XML DOM methods (ChildNodes, SelectNodes, and SelectSingleNode) to navigate the document contents The big difference lies in the fact that XPathNavigator is a distinct component completely decoupled from the document class As mentioned, XPathNavigator represents a generic interface to navigate and read data from any XML-based, or XML-looking, contents The XPathNavigator class enables you to move from one node to the next and perform XPath queries In the .
