You can't read and parse the contents of a PDF using iTextSharp like ... an existing PDF file using iText, you can only ' read ' it page per page. so the overrun can subtly corrupt data that you might not notice for weeks, until the server application crashes. One of the weaknesses of the DCRT overrun checking is that the overrun is reported only after the fact when a memory operation triggers the run through to check for them. It would be better to find a way to immediately stop the instant a program bashed memory just outside its allotted space. Inside Microsoft, they needed a testing tool that would do just that and a few years ago released a tool called PageHeap. PageHeap is actually baked into the operating system and uses a unique trick to catch those overruns instantaneously. When you allocate 16 bytes, PageHeap actually allocates 8 KB! It allocates a 4 KB page, the smallest block of memory that can have access rights applied to it. PageHeap marks that allocated page with read and write access. PageHeap allocates the very next page in memory directly behind the read/write page and marks that page as no access. PageHeap does some pointer arithmetic and hands your program an address that is 16 bytes off the end of the first page. Thus, when you write into the seventeenth byte off that address, you'll write into the page marked as no access so you immediately access violate. Figure 17-2 shows the layout of a PageHeap allocation so that you can visualize what's happening. itextsharp read pdf fields vb.net: Parsing PDF Files using iTextSharp (C#, . NET ) | Square PDF .

To locate one or more nodes in an XML DOM object, you can use either the ChildNodes collection or the SelectNodes method. With the former technique, you are given access to the unfiltered collection of child nodes. Note that in this context, child nodes means all and only the sibling nodes located one level below the current node. The SelectNodes (and the ancillary SelectSingleNode) method exploits the XPath query language to let you extract nodes based on logical conditions. In addition, XPath queries can go deeper than one level and even work on all descendants of a node. The .NET Framework XPath implementation is covered in 6. See the section "Further Reading," on page 244, for resources providing detailed coverage of the XPath query language. 181 vb.net read pdf into byte array Reading A Pdf File Using ITextSharp - C# | Dream.In.Code

I need to read and parse a PDF file that has 50,000 pages. The "Save ... of existing documents and the ability to extract content from documents . Figure 17-2: PageHeap allocation As you can imagine, PageHeap uses a ton more memory than normal However, the cost is dirt cheap if it helps you find the memory overrun If you've got a large application, slap as much memory as possible into the test machine so that your application will turn over Go ahead and steal some out of your manager's machine because he or she won't miss it One key item I do need to mention about PageHeap is that all pointers returned to you have to be on a 16-byte boundary That means if you allocate 10 bytes, you'll have to overrun by 7 bytes in order to hit the no access page The good news is that normally when people overrun a block, it's not just by a byte or two but by a whole gob of them, so PageHeap should still catch them. This also means that PageHeap is worth your while only if you're running a release build of your application With the debug build padding the memory allocation for its own overrun and underrun bytes, you'll never see the PageHeap overrun crash Application Compatibility Toolkit Although I could walk you through a huge discussion of turning on PageHeap with the weird command-line tool built into GFLAGS, there's a much better way to do it The Application Compatibility Toolkit (ACT) not only brings PageHeap functionality right into Visual Studio NET but offers some excellent bug detection tools you should definitely know about Much of ACT is geared toward helping IT administrators get applications running on Microsoft Windows XP and Windows Server 2003, but the Application Verifier (AppVerifier) portion of ACT is where the developer action is. Just getting all the hardware in place to support our Software Plus Services strategy forced Microsoft to develop world-class logistical planning. Product engineers are constantly interacting with the procurement specialists to ensure that the right equipment is in place at the right time. The overhead of managing orders is decreasing and will eventually be fully eliminated. The numbers in Table 14-1 are based upon recent history and projections for the near future. We are constantly dealing with the growth that comes through acquisitions. At the time of this writing, Microsoft is not going to buy Yahoo, but if we do a major acquisition like that later, expect these numbers to change dramatically. Table 14-1: Microsoft Services Factoids Open table as spreadsheet On average, Microsoft adds 10,000 servers to its infrastructure every month. To be fully accessible, an XML document must be entirely loaded in memory and its nodes and attributes mapped to relative objects derived from the XmlNode class. The process that builds the XML DOM triggers when you call the Load method. You can use a variety of sources to indicate the XML document to work on, including disk files and URLs and also streams and text readers. Loading XML Documents The Load method always transforms the data source into an XmlTextReader object and passes it down to an internal loader object, as shown here: public virtual void Load(Stream); public virtual void Load(string); public virtual void Load(TextReader); public virtual void Load(XmlReader); The loader is responsible for reading all the nodes in the document and does that through a nonvalidating reader. After a node has been read, it is analyzed and the corresponding XmlNode object created and added to the document tree. The entire process is illustrated in Figure 5-4. ACT is offered with this book's sample files, or you can download the latest version from http://wwwmicrosoftcom/windowsxp/appexperience/defaultasp The documentation says that ACT 26, the version available to me as I write this book, indicates that AppVerifier runs on Microsoft Windows 2000 SP3 and later, but I've had luck only on Windows XP and 651. On average, the new datacenters Microsoft is building to support Software Plus Services cost about $500 million (USD) and are the size of five football fields. Windows Server 2003 On Windows 2000, I've never gotten the AppVerifier to work properly Additionally, some of the tests and errors the documentation says should work don't seem to produce any output For the rest of this discussion, I'll assume you are using Windows XP or Windows Server 2003 when running AppVerifier and are running under an account with Administrator privileges (as required for AppVerifier) AppVerifier has been designed as a standalone executable (APPVERIFEXE) and as an add-in (VSAPPVERIFDLL) The AppVerifier add-in included with ACT version 26 is integrated into the Debug toolbar of Visual Studio NET 2002 However, that integration is not migrated over to Visual Studio NET 2003 Fortunately, because of all the experience I got with add-ins back in 9, I was able to figure out how to get the AppVerifier add-in working. Figure 5-4: The loading process of an XmlDocument object. Note that before a new XmlDocument object is loaded, the current instance of the XmlDocument object is cleared. This means that if you reuse the same instance of the XmlDocument class to load a second document, the existing contents are entirely removed before proceeding. 182 If you're using a later version of the AppVerifier add-in, it will probably integrate directly into Visual Studio NET 2003, so you can skip the following steps to make it work After you've installed ACT, open a command prompt and navigate to the <ACT installation directory>\Applications directory You'll need to register the AppVerifier add-in DLL with REGSVR32 VSAPPVERIFDLL so that the COM components are in the registry The next step is to tell Visual Studio NET 2003 about the add-in In the AppVerifierAddIn directory with this book's sample files is a REG file named AppVerifierAddInRegregREG You can either double-click the REG file from Windows Explorer or execute it with REGEDIT AppVerifierAddInRegREG In case you're wondering whether bringing an add-in written for a previous version of Visual Studio NET over to a newer version can be a problem, let me tell you that it can be. Although an XML reader is always used to build an XML DOM, some differences can be noticed when the reader is built internally that is, you call Load on a file or a stream or explicitly passed by the programmer. In the latter case, if the reader is already positioned on a nonroot node, only the siblings of that node are read and added to the DOM. If the current reader's node can't be used as the root of a document (for example, attributes or processing instructions), the reader reads on until it finds a node that can be used as the root. Pay attention to the state of the reader before you pass it on to the XML DOM loader. Windows Live WLID (formerly Microsoft Passport) processes more than 1 billion authentications ID per day. Performance Microsoft services infrastructure receives more than 1 trillion rows of performance data every day through System Center (80,000 performance counters collected and 1 million events collected). Microsoft has more than 200 named services and will soon have more than 300 named services. Even this is not an accurate count of services because some, such as Office Online, include distinct services such as Clip Art, Templates, and the Thesaurus feature. vb.net pdf reader VB .NET code to read , convert PDF documents - Yiigo
