NET Framework applications from NuGet.org. Include the following namespaces in the Program.cs file. Exhaustive testing of this particular program includes all valid dates between 1/1/1582 and 12/31/3000 The total number of positive tests is approximately 500,000 If it takes 5 seconds to manually input and verify the correct result of all valid dates in the valid range of dates, it would take one tester approximately 29 days to test the valid inputs exhaustively You might not have time to test all possible variable input combinations doing so is probably not the best use of your time and many tests will have an extremely low probability of providing new information beyond what previous tests have given The assertion you can make with ECP testing is that a valid input of 6/12/2001 would produce the next calendar date on the Gregorian calendar, as would 9/29/1899 and 4/3/2999. vb.net code to extract text from pdf: Reading PDF content with itextsharp dll in VB .

For a more detailed example, see Read and Extract PDF Text in C# and VB . NET from GemBox.Document Examples. As previously stated, one benefit of ECP is that it aids the tester in systematically reducing the number of tests from all possible tests After the data is decomposed into discrete subsets, the next step in the ECP technique is to define how the data subsets will be used in a test The most common approach is to create combinations of valid class subsets for all parameters until all valid class subsets have been included at least once in a validation test Then, test each invalid class subset individually for each parameter while setting the other parameters to some nominal valid value For example, the first test for valid input data would be a combination of valid class subsets v1, v4 (or v6 or v7), and v8. Enable in-process debugging to be used with the Profiling API. Enable JIT-map tracking. Notify on each object allocated from the garbage collected heap. Force rejitting of install-time (NGEN) code generation so that JIT notifications are enabled for those functions. Call function entry and exit hooks. Notify on each non-CLR exception (i.e., all general exceptions). Notify when functions are being unloaded. Notify when a garbage collection is about to occur. Notify on each function just before and after it's JIT-compiled. Notify on each module load and unload. Send no notifications. Notify on each object being allocated on the garbage collected heap. Notify on each remoting context crossing. Notify on each remoting asynchronous event. Generate cookies so that the profiler can pair remoting callbacks. Notify when the CLR is suspended. m_currentAttributeIndex = -1; } When traversing a document using an XML reader, the ReadXml method visits attributes in a loop and reads attribute values using ReadAttributeValue Setting Attributes Attributes are not read through calls made to the Read method A reader provides ad hoc methods to access attributes either randomly or sequentially When one of these methods is called say, MoveToNextAttribute the reader calls an internal method that refreshes the state so that Name and NodeType can now point to the correct content, as shown here: private void SetupAttribute() { m_nodeType = XmlNodeTypeAttribute; m_name = m_tokenValuesKeys[m_currentAttributeIndex]; m_value = m_tokenValues[m_currentAttributeIndex]ToString(); if (m_parentNode == "") m_parentNode = m_name; } A node is associated with a line of text read from the CSV file Each token of information becomes an attribute, and attributes are stored in a collection of name/value pairs. ENTERLEAVE EXCEPTIONS FUNCTION_UNLOADS GC JIT_COMPILATION MODULE_LOADS NONE OBJECT_ALLOCATED REMOTING REMOTING_ASYNC REMOTING_COOKIE SUSPENDS THREADS The test data represented by a combination of these three subsets is any 30-day month, any day between 1 and 30, and any year between 1582 and 3000 Table 5-2 lists the test data inputs for the Next Date program Table 5-2: ECP Test Design Matrix Open table as spreadsheet. Notify on each thread creation and destruction. [*] COR_PRF_ or COR_PRF_MONITOR_ have been removed from flag names for clarity. (This part of the architecture was described in detail in 2) The m_parentNode property tracks the name of the element acting as the parent of the current attribute Basically, it represents the node to move to when MoveToElement is called Again, in this rather simple scenario, a string is sufficient to identify the parent node of an attribute For more complex XML layouts, you might need to use a custom class Reading Attributes Using ReadXml The ReadXml method accesses all the attributes of an element using a loop like this: while (readerMoveToNextAttribute()) { // Use ReadAttributeValue to read attribute values } To load XML data into a DataSet object, the ReadXml method uses an XML loader class that basically reads the source and builds an XmlDocument object This document is then parsed, and DataRow and DataTable objects are created and added to the target DataSet object. Once you return S_OK from your ICorProfilerCallback::Initialize method, you'll receive the notifications you requested through the appropriate ICorProfilerCallback method I'll discuss more about what you'll do with those in a moment because I want to make a point about the only other required method, the ICorProfilerCallback::Shutdown method If the process you're profiling starts life as a managed application, your Shutdown method will always be called However, if your application starts running as a native application that loads the CLR, such as Visual Studio NET, your Shutdown method will never be called To fully handle your profiler being stopped, you'll need to process the DLL_PROCESS_DETACH flag in your profiler's DllMain and check whether your Shutdown method has been called If it hasn't, you'll need to manually clean up, keeping in mind that because the application is ending, you need to be cognizant of what operations you perform.

For an example of how to handle this situation, see the ExceptionMon code Other than the specific algorithms necessary to implement your particular profile, the bulk of your work will be looking up the values passed to the different ICorProfilerCallback notification methods Many of the notification methods are passed an ID value that you can use to retrieve the particular object information These IDs, which are unique to the Profiling API, are simply memory addresses to the items Fortunately, the ICorProfilerInfo interface offers methods to help turn these IDs into real values This generally involves calling the appropriate ICorProfilerInfo method, getting the metadata interface directly related to the ID, and using the metadata interface to do the heavy lifting Metadata refers to the data that describes each NET object Making objects self-describing with metadata is the crux of NET When doing managed development, the metadata is accessible through reflection. When doing native development that needs to access metadata, there's a reader interface, IMetaDataImport, and a writer interface, IMetaDataEmit Most of the work you'll be doing with your profilers will involve reading data with IMetaDataImport The IMetaDataEmit interface is what compilers use to create the metadata in a NET compiled binary The metadata interfaces are discussed in detail in the Metadata Unmanaged APIDOC file, so I'll refer you there because much of the metadata manipulation is pure grunt work Probably the best way to show you how to deal with the IDs and metadata is to show how to return the class and method name from a function ID Function ID values are passed to numerous ICorProfilerCallback methods such as ExceptionUnwindFunctionEnter (to indicate which function is being unwound), JITCompilationFinished (to indicate which function was just JIT compiled), and ManagedToUnmanagedTransition (to indicate which function is transitioning native code). Other Expected result Error Message Error Message Error Message Error Message I16 I18 Error Message Error Message ReadXml uses indirectly To let ReadXml read the value of an attribute, you must provide a significant implementation for ReadAttributeValue In particular, if the current node is an attribute, your implementation should set the new node type to XmlNodeTypeText, increase the depth by 1, and return true public override bool ReadAttributeValue() { if (m_nodeType == XmlNodeTypeAttribute) { m_nodeType = XmlNodeTypeText; m_depth ++; return true; } return false; } ReadAttributeValue parses the attribute value into one or more Text, EntityReference, or EndEntity nodes This means that the XML loader won't be able to read the value unless you explicitly set the node type to Text (We don't support references in our sample CSV reader) At this point, the loader will ask the reader for the value of a node of type Text. vb.net pdf text extract Get/Retrieve/Extract PDF Form Fields VB .
