It shows how you can both read and write form fields using iTextSharp . ns.Add("d", "urn:dino-e-xml"); ns.Add("x", "urn:mspress-xml"); ser.Serialize(writer, emp, ns); After it is populated, the instance of the XmlSerializerNamespaces class is passed on to one of the overloads of the Serialize method. The source class can associate properties with namespaces using a couple of attributes, XmlType and XmlElement, as shown in the following code. In particular, you use XmlType to provide a namespace to all the members of a class. XmlElement applies the namespace information to only the current element. Of course, you can use XmlType and XmlElement together, but can't use XmlType with a property. We'll return to XML attributes in the section "The XmlElement Attribute," on page 501. [XmlType(Namespace ="urn:dino-e-xml")] public class Employee { public string FirstName; [XmlElement(Namespace ="urn:mspress-xml")] public string LastName; public string Position; ... } The resultant XML code is shown here. All the elements have the d prefix except the element that maps to the LastName property. < xml version="1.0" encoding="utf-16" > <Employee xmlns:d="urn:dino-e-xml" xmlns:x="urn:mspress-xml"> <d:FirstName>Dino</d:FirstName> <x:LastName>Esposito</x:LastName> <d:Position>CEO</d:Position> </Employee Serializing Arrays and Collections Class members that evaluate to an array of some type are rendered using a subtree of nodes in which each node renders a single array element. For example, let's initialize the Territories property of the Employee class as follows: emp.Territories = (int[]) Array.CreateInstance(typeof(int), 3); emp.Territories[0] = 1; emp.Territories[1] = 2; emp.Territories[2] = 3; The corresponding XML serialized stream creates three child nodes below <Territories>, one for each element in the array, as shown in the following code. Child nodes are then serialized as instances of the particular type in this case, integer. < xml version="1.0" encoding="utf-16" > <Employee xmlns:d="urn:dino-e-xml" xmlns:x="urn:mspress-xml"> <d:FirstName>Dino</d:FirstName> 398 vb.net itextsharp pdfreader: VB .

This restriction actually makes sense, because the operating system needs to take over the final exception filter when running under a debugger so that the operating system can properly report the final crash to the debugger However, it can make debugging your final crash handler a bit of a pain One workaround you can use to debug your unhandled exception filter is to call it from a 467. vb.net itextsharp pdfreader: Parsing PDF Files using iTextSharp (C#, .

Figure 5-9: Updated pair-wise test matrix using a revised model file to eliminate mutually exclusive variables. You can further customize the PICT model file by aliasing or making some variable states equivalent. For example, the Arial font and the Tahoma font are very similar font types, so you could assert that Arial is equivalent to Tahoma when tested in combination with variable states from other parameters. You can alias the Arial and Tahoma font by removing the comma and inserting a pipe character (|) between the Arial and Tahoma variable states in the PICT model file, as illustrated in the following code example. Using another feature of the PICT tool, you can potentially increase the occurrences of highly probable combinations or variable states in the output of test combinations. For example, you can assert that the most common font color is black and the most common font size is a nominal font size. Again, you can modify the PICT input model file by providing weights to those variable states as illustrated in the following code. A weighted variable state is useful to give preference to a value once all n-wise conditions are satisfied for that variable state. itextsharp read pdf fields vb.net Parsing PDF Files using iTextSharp (C#, .

You can't 'parse' an existing PDF file using iText , you can only ' read ' it page per page. What does this mean? The pdf format is just a canvas ... regular SEH exception filter. You can find an example of this workaround in the Baz function in BugslayerUtil\Tests\CrashHandler\CrashHandler.CPP, which is part of this book's source code. Another issue is that the exception filter you specify by calling SetUnhandledExceptionFilter is global to your process. If you build the coolest crash handler in the world for your ActiveX control and the container crashes even if it's not your fault your crash handler will be executed. Don't let this possibility keep you from using SetUnhandledExceptionFilter, though. I have some code that might help you out. Common Debugging Question: Is there anything you can do to fix blown stacks from infinite recursion Infinite recursion is not, thank goodness, that common, but when it does happen, it's nearly impossible to debug. If you've ever seen an application appear to pause for a second or so and completely disappear without displaying an Application Error dialog box, you're almost certainly looking at infinite recursion. If you can't even get a chance to debug the application, it's very hard to figure out what went wrong with it. Fortunately, the new _resetstkoflw C run-time function attempts to get you some stack space so that you can at least report the error. If you'd like to see how _resetstkoflw does its magic, check out its implementation, which is included in RESETSTK.C. <x:LastName>Esposito</x:LastName> <d:Position>CEO</d:Position> <d:Territories> <d:int>1</d:int> <d:int>2</d:int> <d:int>3</d:int> </d:Territories> </Employee> Classes that must be serialized to XML can't use most of the more common collection classes For example, the ArrayList class is serializable, but NameValueCollection, Hashtable, and ListDictionary are not The reason lies in the extra constraints set for the classes that implement ICollection and IEnumerable In particular, a class that implements IEnumerable must also implement a public Add method that takes a single parameter This condition filters out dictionaries and hash tables but keeps ArrayList and StringCollection objects on board In addition, the type of the argument you pass to Add must be polymorphic with the type returned by the Current property of the underlying enumerator object A class that implements the ICollection interface can't be serialized if it does not have an integer indexer that is, a public Item indexed property that accepts integer indexes. Using the CrashHandler API In the reusable module BUGSLAYERUTIL.DLL, I wrote the CrashHandler API, which you can use to limit your crash handler to a specific module or modules. I limit your crash handler by making all unhandled exceptions pass through an unhandled exception filter that I set. When my unhandled exception filter is called, I check the module that the exception came from. If the exception is from one of the specified modules, I call your crash handler, but if it's from a module outside those that were specified, I call the unhandled exception filter I replaced. Calling the replaced exception filter means that multiple modules can use my CrashHandler API without stepping on one another. If no modules are specified, your crash handler will always be called. You can see all the CrashHandler API functions in Listing 13-4. I strongly encourage you to read the code over because if you understand it, you'll learn quite a bit about exception handling, using the DBGHELP.DLL symbol engine, and how to walk the stack.
