In the current version of the file dumper application, the main thread waits until a file is changed or a timeout of 60 seconds is reached. Instead of blocking the main thread, you could use it to allow the user to decide when to stop waiting while another thread deals with file modifications. The FileSystemWatcher s EnableRaisingEvents property provides a simple way to achieve this. The FileSystemWatcher provides five events that can be fired when the EnableRaisingEvents property is set to true. The one that is interesting for the ChangedFileDumper class is the Changed event. As discussed previously, the gcroot and auto_gcroot templates overload the member access operator (operator->) so that you can easily access members of the wrapped tracking handle. This allows you to easily call member functions on the wrapped object or set the EnableRaisingEvents property to true. However, as soon as you want to register an event via the auto_gcroot variable fsw, you will face an additional problem. The following code will not compile: class ChangedFileDumper { auto_gcroot<FileSystemWatcher^> fsw; public: ChangedFileDumper(std::string path) : fsw(gcnew FileSystemWatcher) { fsw->Path = gcnew String(path.c_str()); fsw->EnableRaisingEvents = true; fsw->Changed += gcnew FileSystemEventHandler(this, & ChangedFileDumper::OnChanged); // error C3364: "invalid argument for delegate constructor" } private: void OnChanged(Object^ sender, FileSystemEventArgs^ e) { DumpFile(e->FullPath); } void DumpFile(String^ name) { StreamReader sr(name); Console::WriteLine(sr.ReadToEnd()); } }; ean 13 barcode generator javascript EAN13 . java ยท GitHub

Therefore, rather than migrating the entity bean to EJB 3, we used inheritance and a single-table-per-entity hierarchy, as shown in listing 14.2. Figure 14.4 shows the results of the entity refactoring. @Entity @Table(name = "USERS") @Inheritance(strategy = InheritanceType.SINGLE_TABLE) @DiscriminatorColumn(name = "USER_TYPE", discriminatorType = DiscriminatorType.STRING, length = 1) User superclass public class User { } @Entity @DiscriminatorValue(value = "S") public class Seller extends User { } @Entity @DiscriminatorValue(value = "B") public class Bidder extends User { } ean 13 check digit java code Check digit - Wikipedia

This Java barcode generator is specified for EAN - 13 generation which can draw super quality EAN - 13 barcodes with 2 or 5 supplement data encoded in Java ... You can also start adding the operations to the associated XML schema file, so that they are there when you need them in the future (The sample project for this chapter includes two versions of the StockTrader XML schema file: StockTraderxsd and StockTraderWithOperationsxsd). Figure 14.4 While migrating EJB 2 entity beans to EJB 3, it is likely you ll want to refactor to take advantage of features like OO inheritance support. In our example, the UserBean entity bean can be refactored into a User POJO entity superclass and Bidder, Seller, and so forth entity POJO subclasses. ean 13 check digit java code Welcome to Barcode4J

Methods inherited from class java .lang.Object · clone, equals ... The event handler must match the requirements of delegate target functions. Unfortunately, ChangedFileDumper::OnChanged (as well as all member functions of native classes) cannot be used as a delegate target. Only global functions and static and non-static methods of managed types can act as delegate targets. To solve this problem, you could create a managed proxy class that provides a target function. Such a proxy class can be defined inside ChangedFileDumper because native classes can have nested managed classes. To avoid implementing any application logic inside the proxy class, it should simply forward to the real event handler in the native class. It is not necessary to write all the code for such a proxy class manually, because Visual C++ comes with helper macros in the header file msclr/event.h. Inside a public area of your class, you can define a delegate map. The macros BEGIN_DELEGATE_MAP and END_DELEGATE_MAP create the frame of a delegate map. For every event that should be handled in the native class, one entry should appear in this delegate map. The macro EVENT_DELEGATE_ENTRY produces these entries. To instantiate a delegate for the registration or unregistration of an event, the MAKE_DELEGATE macro is used. The code shown here implements the same application as before, but now a native class and the macros from msclr/event.h are used: // DumpChangedFiles2.cpp // cl /clr DumpChangedFiles2.cpp #include <string> #include <vcclr.h> #include <msclr/auto_gcroot.h> using msclr::auto_gcroot; #include <msclr/event.h> #using <System.dll> using namespace System; using namespace System::IO; class ChangedFileDumper { auto_gcroot<FileSystemWatcher^> fsw; public: ChangedFileDumper(std::string path) : fsw(gcnew FileSystemWatcher) { fsw->Path = gcnew String(path.c_str()); fsw->EnableRaisingEvents = true; fsw->Changed += MAKE_DELEGATE(FileSystemEventHandler, OnChanged); } BEGIN_DELEGATE_MAP(ChangedFileDumper) EVENT_DELEGATE_ENTRY(OnChanged, Object^, FileSystemEventArgs^) ean 13 barcode generator javascript Generate EAN - 13 barcode in Java class using Java ... - OnBarcode
