NET Framework applications from NuGet.org. Include the following namespaces in the Program.cs file. Figure 6-7: Control flow diagram for CreateNewFile function. Decision testing of the CreateNewFile function requires a minimum of two tests of this function. For the first test, we pass a file name as an argument to this function that exists on the system to force the conditional clause to evaluate to its true outcome. A second decision or branch test requires us to pass a valid file name that does not exist as an argument to this function to evaluate the false outcome of the conditional clause. Although this is a simple example, it demonstrates how decision testing provides better sensitivity to control flow for simple conditional clauses as compared to block coverage. Also note that we are not passing invalid file name strings to the myFilename parameter to check for various error conditions. The purpose of structural testing is not to test all possible inputs or outputs, but simply to help us test control flow through a function. In this example, we assume that the myFilename string is validated somewhere else and a valid string is passed as an argument to the myFilename parameter. However, testers should be cautious with looping structures because it is easy to design ineffective tests that evaluate both the true and false outcomes of the conditional clause without effectively testing the loop structure. For example, we could design one test for the GetCharacterCount function and pass an argument of A to the myString parameter and an argument of A to the myCharacter parameter, which would evaluate the conditional clause in the for loop as true. The next iteration through the loop evaluates the conditional clause as false because the index value is equal to the length of the myStringArray variable.

9 May 2014 ... This article will explain how we can read a PDF file in ASP. ... here I will show you to read PDF file using iTextSharp both in C# and VB . NET . As you can see, the first file created is a C# source file whose name has been randomly generated. Next the serializer invokes the C# compiler, and the assembly is soon created! The files are cached in memory and deleted from disk immediately after having been created. It's almost impossible to programmatically catch those files and make a copy for further perusal. The XML Serialization Notifier tool (XmlSerial_CS) shown in Figure 11-5 (and available in this book's sample files) uses the FileSystemWatcher class to monitor file system events that take place in a given folder. The only trick I've come up with to get my hands on the serializer's internal files is dropping the delete permission on the folder. Figure 11-6 shows the files generated using this trick for the serializer instance shown in Figure 11-5. // The common epilog for the naked functions, // SnapCurrentProcessMiniDumpA and SnapCurrentProcessMiniDumpW. 507 private static int GetCharaacterCount (string myString, char myCharacter) { char[] myStringArray = myString.ToCharArray(); int result = 0; for (int i = 0; i < myStringArray.Length; i++) { if (myStringArray[i] == myCharacter) { result++; } } return result; } vb.net itextsharp pdfreader VB PDF text extraction tutorial - ByteScout

Serialization Writers and Readers Let's take a brief look at what happens under the hood of the XmlSerialization-Reader and XmlSerializationWriter classes. The MSDN documentation touches on these two classes, which form the substrate of the classes contained in the temporary assembly. The XmlSerializationReader and XmlSerializationWriter classes are internal and are not intended to be used directly from user code. More interesting than the actual contents of the classes is how the Serialize and Deserialize methods interact with them. Serializing to XML The Serialize method first gets a reference to the class-specific type writer. An instance of the XmlSerializationWriter1 class is returned by the TempAssembly class that represents the temporary assembly. Once the Serialize method holds a reference to the actual serialization writer, it calls the write method that outputs XML code to a text writer. Deserializing from XML Although a CanDeserialize method is provided, the Deserialize method never calls it. If the type is not fully serializable, or if errors occurred somewhere along the way, the Deserialize method fails, throwing an exception. If no errors occur, the Deserialize method asks the temporary assembly to return a reference to the reader object to be used. The reader object is simply an instance of the XmlSerializationReader1 class. The method that actually returns the object is one of the ReadN_XXX methods, where N is the method index and XXX is the type. SNAPEPILOG(eRetVal) /* Restore saved registers. */ ECX EBX EDI ESI /* Set the return value. */ A more effective test strategy for decision testing is to execute a minimum of three tests for more comprehensive structural testing of this function. The basis path testing technique described later in this chapter provides a technique that ensures that a more thorough set of structural tests for functions with simple conditional clauses is used. Also note that there are additional tests that we would want to design to completely test the capabilities of this function, but for decision testing of the function, we require only two tests. The XML serializer is a double-edged sword On one hand, it lets you serialize and deserialize even complex NET Framework classes to and from XML with very few lines of code To accomplish this, the serializer needs to create an assembly on the fly If you don't use a global instance of the serializer for each type, you can easily add hundreds of milliseconds of overhead to each call definitely not a pleasant prospect On the other hand, appropriately used, XML serialization produces more compact code than run-time SOAP serialization If you add type information, and SOAP type information in particular, the ratio changes, however The moral of this story is don't ever mix XML and SOAP use only the process you need Serialization is one of the new frontiers of XML. LPCWSTR szDumpName , PCONTEXT ) { // Assume the best. BSUMDRET eRet = eDUMP_SUCCEEDED ; // Have I even tried to get the exported MiniDumpWriteDump function // yet if ( ( NULL g_eIMDALastError)) { if ( FALSE == IsMiniDumpFunctionAvailable ( ) ) { eRet = g_eIMDALastError ; } } // If the MiniDumpWriteDump function pointer is NULL, I'm done. if ( NULL == g_pfnMDWD ) { eRet = g_eIMDALastError ; 508 == g_pfnMDWD ) && ( eINVALID_ERROR == pCtx } if ( eDUMP_SUCCEEDED == eRet ) { // Armed with the context at the time of the call to this // function, I can now look to actually writing the dump. To // make everything work, I need to make it look like an // exception happened. Hence, all this work to fill out the // MINIDUMP_EXCEPTION_INFORMATION structure. EXCEPTION_RECORD stExRec ; EXCEPTION_POINTERS stExpPtrs ; MINIDUMP_EXCEPTION_INFORMATION stExInfo ; // Zero out all the individual values. ZeroMemory ( &stExRec , sizeof ( EXCEPTION_RECORD )) ; ZeroMemory ( &stExpPtrs , sizeof ( EXCEPTION_POINTERS ) ) ; ZeroMemory ( ,sizeof(MINIDUMP_EXCEPTION_INFORMATION)); &stExInfo In general, decision testing provides greater sensitivity to control flow as compared to block testing. Decision testing is effective for simple conditional clauses in which one Boolean conditional clause is being evaluated such as if statements or looping structures. But, similar to block testing, decision tests do not adequately evaluate relational operators in a conditional clause. The decision tests for the conditional clause It is not clear yet whether today's SOAP, extensions to SOAP, or a brand-new dialect will become the universal platform for describing objects Currently, XML serialization is a hybrid, incomplete, technology Originally designed as a tool running underneath the NET Framework implementation of Web services, XML serialization entered prime time a bit too early, or if not too early, certainly not optimized If you look at XML serialization as a way to save and resume objects to and from a tagbased description, the current architecture makes sense because it is fairly unobtrusive and even efficient The apparently odd use of a temporary assembly is fully justified in a Web service context As we'll see in 13, the return type of a Web method is serialized back to the caller using an instance of the XmlSerializer class. // Set the exception address to the start of the CALL // instruction. Interestingly, I found I didn't have to set the // exception code. When you open up a .DMP file created // with this code in VS.NET, you'll see the exception code // reported as: // 0x00000000: The operation completed successfully. // warning C4312: 'type cast' : conversion from 'DWORD' // to 'PVOID' of greater size #pragma warning ( disable : 4312 ) stExRec.ExceptionAddress = (PVOID)(pCtx->Eip) ; #pragma warning ( default : 4312 ) // Set the exception pointers. stExpPtrs.ContextRecord = pCtx ; stExpPtrs.ExceptionRecord = &stExRec ; // Finally, set up the exception info structure. stExInfo.ThreadId = GetCurrentThreadId ( ) ; stExInfo.ClientPointers = TRUE ; 509 vb.net code to extract text from pdf How to Extract Text from PDF Document in C#, VB .
