16 Aug 2018 ... Syncfusion Essential PDF is the . NET PDF library used to create, read , and edit PDF documents . Using this library, you can extract text from ... FLS file in that directory instead of the directory in which the executable resides To keep everything straight for multithreaded applications, FlowTrace's output writes each thread to a different file The file naming is as follows: <process name>_<Win32 process ID>_<managed thread ID>FLOW The different parts of the filename should be self-explanatory The only interesting part is that I used the managed thread ID instead of a Win32 thread ID As you'll see later in the implementation section, there's no correlation between a managed thread and a Win32 thread Your final task before using FlowTrace is setting up the optional settings file The file is a simple initialization file located in the same directory as the executable or where the FLOWTRACEFILEDIR environment variable points, and it is the program name with an FLS extension. Although I could have used the ultramodern technique of an XML file, I just didn't feel like spending several months writing and testing code that uses MSXML3DLL from C++ and bloating the FlowTrace working set by tens of megabytes There is no sense in making things more complicated than they have to be The first of the three optional settings supported by FlowTrace is determining whether inlining should be on By default, inlining is turned on so that the process running under FlowTrace will run faster The second option is disabling logging of the finalizer thread All NET processes have the garbage collector running in a separate thread I found that the majority of calls made on the finalizer thread were related to cleaning up the CLR-created objects. Test Month Day Year 8 9 10 11 12 13 14 15 16 17 18 19 1 12 1 12 1 12 1 12 1 12 1 12 1 12 1 12 1 12 1 12 1 12 1 12 1 2 30 31 32 For example, suppose that you perform the following operation on an unchanged row: // 1 is the current value of the field row[0][field] = 2; The row state changes to Modified, the original value (1) is persisted in the Original copy of the row, and the new value (2) is registered as the current value Next the following code runs: // 2 is the current value of the field // 1 is the original value of the field row[0][field] = 3; // 3 is NOW the current value of the field // 1 is the original value of the field The original copy of the row remains intact, but the current version is updated As a result, the intermediate value (2) is overwritten and is irreversibly lost Note Building an automatic mechanism for tracking the entire history of a row is probably unnecessary in most cases. To keep the output to a minimum, I preferred to record only the real process flow on the other threads because that's more informational in my opinion Therefore, by default, FlowTrace doesn't record the finalizer thread, but you can easily enable that recording The third option lets you decide whether to record the startup code for the initial AppDomain created on the main thread since the SystemAppDomainSetupDomain method creates huge amounts of trace output By default, I don't record the startup In Listing 11-2 is a default FLS file To enable a particular option, set it to 1; a 0 (zero) disables it Listing 11-2: A Default FLS File ; This is an example FLS configuration file Name this file ; the same name as the executable and put it in the same ; directory as the EXE ; All general options are here. All values shown are the defaults ; if no FLS file is present for the executable 430. If you need a more powerful mechanism to track changes, you can build a parallel table of changes for each row in the table Each entry in the custom table would point to a particular DataRow object and contain a collection of changes organized as you prefer.. Expected result Notes Day minimum, Month nominal, Year nominal Day minimum +1, Month nominal, Year nominal Day maximum -1, Month nominal, Year nominal Day maximum, Month nominal, Year nominal Day maximum +1, Month nominal, Year nominal Year minimum -1, Day nominal, Month nominal Year minimum, Day nominal, Month nominal Year minimum +1, Day nominal, Month nominal Year maximum -1, Day nominal, Month nominal Year maximum, Day nominal, Month nominal Year maximum +1, Day nominal, Month nominal All nominal conditions [General Options] ; Turns off inlining if set to 1 This will lead to much ; larger trace flows TurnOffInlining=0 ; Does not process anything in the finalizer thread IgnoreFinalizerThread=1 ; Skips all AppDomain startup calls on the main thread SkipStartupCodeOnMainThread=1 FlowTrace Implementation Highlights Now I want to discuss a few of the implementation highlights The first big issue I ran into was that in the future, managed threads won't have a one-to-one mapping with Win32 threads The first versions of the Microsoft NET Framework do have a one-to-one mapping I first implemented FlowTrace using the reliable standby of thread local storage to ensure each thread had specific data As I was perusing through ProfilingDOC, I noticed a special thread notification, ICorProfilerCallback::ThreadAssignedToOSThread. The description mentions that in the context of a CLR runtime thread, "During its execution lifetime, a given Runtime thread may be switched between different threads, or not at the whim of both the Runtime and external components running within the process" That sure got my attention, and after checking with Microsoft, I realized the simple thread local storage solution wasn't going to work because FlowTrace would break in the future Fortunately, thread creation and destruction notifications in ICorProfilerCallback will give you the managed thread ID as a parameter, and you can call ICorProfilerInfo::GetCurrentThreadID to learn the thread ID at any time, so you'll have no issues identifying a managed thread The downside is that I had to create my own "managed thread local storage" in a global Standard Template Library (STL) map class. Tracking Pending Errors The DataRow class provides a few methods for handling row errors. You can set a general error message on the entire row, and you can set a column-specific message. To set a general error message, you use the RowError property. To set a columnspecific message, you use the pair of methods SetColumnError and GetColumnError. Other helper methods available are GetColumnsInError and ClearErrors. A column or row with an error is in no way different from a column or row without pending errors. In this context, an error is simply a description of contents that the user, or the application, finds erroneous and inconsistent. Nothing prevents you from using error properties as general-purpose cargo variables in which to store custom information and annotations. Note If you choose to use error properties as general-purpose cargo variables, keep in mind that some advanced Windows Forms and Web Forms controls can, in the presence of error flags, refresh their own user interfaces accordingly. For example, the Windows Forms 370 1582 3000 Next date 1582 3000 Next date 1582 3000 Next date 1582 3000 Next date 1582 3000 Error Error Next date Next date Next date Next date Error itextsharp read pdf line by line vb.net Extract Text from PDF in C# (100% .
