6 Mar 2019 ... NET PDF text extractor library & . NET PDF to text converter library. Easy to extract text from PDF file and convert PDF to txt file in C# & VB . This chapter touches on a number of topics that you might want to know more about. Some are XML-related, but not so much .NET-related as to find an ideal place for discussion here. Some are not really XML-related but definitely belong to the .NET Framework and, as such, deserve at least a reference here. One topic we spent a lot of time on in this chapter is XML namespaces and qualified names. The official site where the specification can be found is http://www.w3.org/TR/REC-xml-names. In 3, I covered XML validation and the various schema involved in the process. If you think you need an XML crash course from a higher, non-.NET-Framework-related perspective, I can recommend two books. One is Essential XML, by Don Box, John Lam, and Aaron Skonnard (Addison-Wesley, 2000). This reference is great if you need to get the gist of XML in a platformindependent and language-independent context. Otherwise, look at the XML Programming Core Reference, by R. Allen Wyke, Sultan Rehman, Brad Leupen, and Ash Rofail (Microsoft Press, 2002), for more development-related considerations and tips. A great source for learning about underdocumented features and tricks of the .NET Framework is certainly Jeffrey Richter's most recent book, Applied .NET Framework Programming (Microsoft Press, 2002). This book is a gold mine for all that boring stuff 166 vb.net open pdf file in adobe reader: Converting files to bytes in VB .

It is also important to track changes made to specifications and other documents. Many applications can track the changes made to a document. The chapters in this book, for example, pass from authors to reviewers to editors and back again. At each stage, a reviewer might make several edits and suggestions. All changes are tracked within Microsoft Office Word so that each of the authors can track progress as well as document and refer to the discussions leading up to wording or content decisions. Word can also compare two documents even if the reviewer forgets to activate the Track Changes feature, as shown in Figure 12-2. This is convenient for checking the changes made between two versions of a document and for reviewing the changes, for example, when reviewing edits made simultaneously by several reviewers. vb.net pdf reader control C# / VB .

Read ... that revolves around string manipulation, character encoding, and memory management. One of the examples discussed in this chapter entails the creation of an XML ADO Recordset object from ADO.NET specific objects such as DataSet, DataTable, and DataView. A more thorough discussion of the integration between ADO and ADO.NET can be found in 8 of my book Building Web Solutions with ASP.NET and ADO.NET (Microsoft Press, 2002). Although that book is markedly ASP.NET-specific, the theme of how to efficiently use ADO from .NET Framework applications is fairly platform-independent and can be applied to Windows Forms as well. Finally, this chapter touches on .NET code security. If you need to get started with security and are looking for a long-range perspective with concrete code snippets sprinkled here and there, by all means check out Jason Clark's excellent article at http://msdn.microsoft.com/msdnmag/issues/02/06/rich/rich.asp. Filling data structures, especially lists and arrays, is another excellent use of Set Next Statement when you're testing or debugging If you have some code that fills a data structure and adds the data structure to a linked list, you can use Set Next Statement to add some additional items to the linked list so that you can see how your code handles those cases This use of Set Next Statement is especially handy when you need to set up hard-to-duplicate data conditions when you're debugging Common Debugging Question: Can Visual Studio NET also debug regular ASP Web applications It sure can, but not out of the box because you have to add some registry keys and set up DCOM permissions on the Web server It's hard to find the steps because they're buried way down deep in the documentation. Search for the topic "ASP Remote Debugging Setup" to see the necessary steps Summary Visual Studio NET debugging is the state-of-the-art debugger on the market today Microsoft listened to developers and produced a debugger that makes some extremely difficult debugging problems much easier to debug This chapter introduced the common breakpoint features across managed and native code As you've seen, the debugger can do a considerable amount of work for you if you know how to utilize it effectively You should strive to make the most of the Visual Studio NET debugger so that you can minimize the time you spend in it Advanced breakpoints help you avoid tedious debugging sessions by allowing you to specify the exact conditions under which a breakpoint triggers. A question I hear often from testers when teaching introductory testing and debugging courses at Microsoft is "How far should I debug " Developers, interestingly enough, often ask, "How far should I expect testers to debug " The answer to both questions is, of course, "It depends" Debugging is detective work Examining states of variables in a live debugging session, examining log files, and examining changes in source code are all methods of debugging, that is, attempting to find the cause of an error The challenge for many new testers (and developers) is to understand at what point between "find a bug" and "fix a bug" does their work stop Many testers are as good as (and sometimes better than) the developers they work with on investigating and isolating the cause of a bug. 5: The XML .NET Document Object Model 6: XML Query Language and Navigation 7: XML Data Transformation While both managed and native code have special breakpoint features, the location breakpoint modifiers, hit counts, and condition expressions are your best friends, mainly because the breakpoint modifiers will save you a huge amount of time since they'll allow you to use the debugger more efficiently I strongly encourage you to play with them a bit so that you can see what you can and can't do, thus avoiding having to learn their idiosyncrasies under extreme pressure.. On some Microsoft teams, testers routinely debug errors to the point of isolating the file, line number, and check-in that caused the bug, while on other teams, testers might do little investigative work beyond reporting the bug Nearly all testers at Microsoft are capable of debugging to a deep extent, so the decision comes down to time constraints and expectations Time investment can be a factor if a test team is understaffed, behind schedule, or bound on some other critical resource In other words, sometimes a test team just doesn't have time to debug errors completely Expectations, however, are the much more important aspect of this dilemma I've known developers who didn't want testers debugging their code, and I've known testers who didn't want to debug someone else's code I personally don't like either of these scenarios. pfnV ) In addition to XML readers and writers, the Microsoft .NET Framework provides classes that parse XML documents according to the W3C Document Object Model (DOM) Level 1 Core and the DOM Level 2 Core. These classes, available in the System.Xml namespace, build a complete in-memory representation of the contents of an XML document and make it programmatically accessible during both read and write operations. The structure of the XML Document Object Model (XML DOM) is a general specification that is implemented using platform-specific features and components. The MSXML library provides a COM-based XML DOM implementation for the Microsoft Win32 platform. The System.Xml assembly provides a .NET Framework-specific implementation of the XML DOM centered on the XmlDocument class. Although it is stored as flat text in a linear text file, XML content is inherently hierarchical. Readers simply parse the text as it is read out of the input stream. They never cache read information and work in a stateless fashion. As a result of this arrangement, you can neither edit nodes nor move backward. The limited navigation capabilities also prevent you from implementing node queries of any complexity. The XML DOM philosophy is quite different. XML DOM loads all the XML content in memory and exposes it through a suite of collections that, overall, offer a tree-based representation of the original content. In addition, the supplied data structure is fully searchable and editable. Advanced searching and editing are the primary functions of the XML DOM, whereas readers (and Simple API for XML [SAX] parsers as well) are optimized for document inspection, simple searching, and any sort of read-only activity. In 2, we explored the characteristics of pull mode readers. Let's analyze now the .NET Framework programming interface for full-access XML document processing. // The macros that map the C-style allocations. It might be easier if // you use macros to wrap these so that you don't have to remember which // BSMDVINFO block value to drag around with each memory usage function. #define MEMDEBUG_MALLOC(lpBSMDVINFO , nSize) _malloc_dbg ( nSize __FILE__ __LINE__ _realloc_dbg( pBlock nSize __FILE__ __LINE__ _expand_dbg( pBlock nSize __FILE__ __LINE__ #define MEMDEBUG_FREE(lpBSMDVINFO , pBlock) _free_dbg ( pBlock , \ ((LPBSMDVINFO)lpBSMDVINFO)->dwValue ) #define MEMDEBUG_MSIZE(lpBSMDVINFO , pBlock) _msize_dbg >dwValue ) // Macro to call ValidateAllBlocks #define VALIDATEALLBLOCKS(x) #else ValidateAllBlocks ( x ) ( pBlock , ((LPBSMDVINFO)lpBSMDVINFO), , ) \ \ \ , \ \ \ \ \ , \ \ \ \ , , , ) , , , ) ((LPBSMDVINFO)lpBSMDVINFO)->dwValue , \ \ \ \ vb.net read pdf file itextsharp how to read pdf files-VBForums
