We have two major organizational models for the engineering workforce. As a business goes from incubation to maturity, it may evolve from one model to another. When Office first started, it wasn't even Office. It was Word and Excel, and then PowerPoint and Access. For several releases each product was developed and shipped independently. This model for greater independence to ship is often referred to as the PUM (Product Unit Manager) model, and is the most common across Microsoft. With the PUM model a team manages all the engineering assets they need (or at least can get) in one single organization. They typically do not have to take dependencies on other teams unless it's for some technology another team is close to shipping. The PUM model is ideal for rapid shipping and adjusting to competitors, but it does not allow for the centralization of common functions, such as build or test automation tools. With this approach, duplication of effort is higher, as is communications overhead. Almost every product, no matter how mature, still has some of these smaller teams within it. Both Microsoft Office and Windows still use the PUM model for incubation features while trying to ship major versions. vb.net read pdf to text: How to read PDF files in VB . net or convert PDF to word document in ... vb.net extract text from pdf How to Extract Text from PDF Document in C#, VB .

NET · Convert PDF in CSV – C# sample source code . NET Framework supplies the following reader classes: XmlTextReader Extremely fast; the reader ensures that the XML source is well-formed but neither validates it against a schema or a DTD nor resolves any embedded entity XmlValidatingReader An XML reader that can validate the source using a DTD, an XML-Data Reduced (XDR) schema, and an XML Schema Definition (XSD) In addition, the reader is capable of expanding entities and also supports default attributes as defined in the DTD or schema XmlNodeReader The reader specializes in parsing XML data from an XML Document Object Model (XML DOM) subtree and does not support validation In the next section, we'll examine the XmlTextReader class probably the most frequently used NET reader class Validating readers will be covered in 3; 27. // The handle to the debug thread HANDLE hDbgThread = INVALID_HANDLE_VALUE ; // Try to create the thread.

By the end of this chapter, you'll also have had in-depth exposure to the intricacies (and the flexibility) connected with the development of a custom reader class. DebugThread , ASSERT ( INVALID_HANDLE_VALUE != hDbgThread ) ; if (INVALID_HANDLE_VALUE == hDbgThread ) { VERIFY ( CloseHandle ( hStartAck ) ) ; return ( INVALID_HANDLE_VALUE ) ; } // Wait until the debug thread gets good and cranking.

VERIFY ( CloseHandle ( hStartAck ) ) ; // Check that the debug thread is still running. If it isn't, // the debuggee probably couldn't get started.

BOOL bCreateDbgSyncEvts = Beizer, Black-Box Testing: Techniques for Functional Testing of Software and Systems (New York: John Wiley, 1995). Beizer, Software Testing Techniques, 2nd ed. (New York: Van Nostrand Reinhold, 1990). The XmlTextReader class is designed to provide fast access to streams of XML data in a forward-only and read-only manner The reader verifies that the submitted XML is well-formed It also performs a quick check for correctness on the referenced DTD, if one exists In no case, though, does this reader validate against a schema or DTD If you need more functionality (for example, validation), you must resort to other reader classes such as XmlNodeReader or XmlValidatingReader An instance of the XmlTextReader class can be created in a number of ways and from a variety of sources, including disk files, URLs, streams, and text readers To process an XML file, you start by instantiating the constructor, as shown here: XmlTextReader reader = new XmlTextReader(file); Note that all the public constructors available require you to indicate the source of the data, be it a stream, a file, or whatever else. CreateDebugSyncEvents *lpPID ) ; ASSERT ( TRUE == bCreateDbgSyncEvts ) ; if ( FALSE == bCreateDbgSyncEvts ) { // This is a serious problem. I got the debug thread going, but // I was unable to create the synchronization events that the // user interface thread needs to control the debug thread. My // only option here is to punt. I'll kill the // debug thread and just return. I can't do much else. TRACE ( "StartDebugging : CreateDebugSyncEvents failed\n" ) ; VERIFY ( TerminateThread ( hDbgThread , (DWORD)-1 ) ) ; VERIFY ( CloseHandle ( hDbgThread ) ) ; return ( INVALID_HANDLE_VALUE ) ; } // Just in case someone modifies the function and fails to properly // initialize the returned value. ASSERT ( INVALID_HANDLE_VALUE != hDbgThread ) ; // Life is good! return ( hDbgThread ) ; } The first functional testing technique testers should learn to master is equivalence class partitioning (ECP) Understanding how to use this technique is important because it provides a foundation for many other techniques and approaches to software testing The ECP technique is simply a tool that enables the tester to evaluate input or output variables systematically for each parameter in a feature But to be most effective equivalence class partitioning requires us to perform a comprehensive analysis of the variable data for each parameter in the context of the specific system So, before designing the ECP tests, we must meticulously decompose and model the variable data for each input and/or output parameter in discrete subsets of valid and invalid classes. The default constructor of the XmlTextReader class is marked as protected and, as such, is not intended to be used directly from user's code After the reader is up and running, you have to explicitly open it using the Read method This behavior is not unique to XML readers, it is common to all NET reader components Readers move from their initial state to the first element using only the Read method To move from any node to the next, you can continue using Read as well as a number of other more specialized methods, including Skip, MoveToContent, and ReadInnerXml To process the entire content of an XML source, you typically set up a loop based on the return value of the Read method The Read method returns true if there's more content to be read, and false otherwise. Assertions in .NET Windows Forms or Console Applications Before I get into the gritty details of .NET assertions, I want to mention one key mistake I've seen in almost all .NET code written, especially in many of the samples from which developers are lifting code to build their applications. Everyone forgets that it's entirely possible to have an object parameter passed as null. Even when developers are using assertions, the code looks like the following: void DoSomeWork ( string TheName ) { Debug.Assert ( TheName.Length > 0 ) ; Instead of triggering the assertion, if TheName is null, calling the Length property causes a System.NullReferenceException exception in your application, effectively crashing it. This is the horrible case where the assertion is causing a nasty side effect, thus breaking 73 Accessing Nodes The following example shows how to use an XmlTextReader object to parse the contents of an XML file and build the node layout Let's begin by considering the following XML data: <platforms type="software"> <platform vendor="Microsoft">NET</platform> <platform vendor=""OpenSource="yes">Linux</platform> <platform vendor="Microsoft">Win32</platform> <platform vendor="Sun">Java</platform> </platforms> The corresponding node layout that we want to extrapolate consists of a block of XML data that comprises all the element nodes of the source file, as shown here: <platforms> <platform> </platform> <platform> </platform> <platform> </platform> 28. itextsharp read pdf fields vb.net How to Extract Text from PDF Document in C#, VB .
