It s restarted due to AudioClip s restriction that multiple instances of the same clip can t be played concurrently This stutter may not be a drawback for some applications, but it should be avoided in ArmsPad3D If there s still a collision after the sound s end, it can be played again then Another aspect of sound playing is that it shouldn t freeze the rest of the application; a sound effect may last for 1 to 2 seconds, which is much too long for the grabbers to be unresponsive The simplest solution is to use a thread to play the sound, but this may be seriously inefficient The issue is that each time the sound needs to be played, a new thread is created, with the associated overheads of thread creation and subsequent termination. c# add watermark to existing pdf file using itextsharp Display watermark image in PDF using iTextsharp in ASP.Net, C# and ...

PDF for .NET Library : A better solution is to keep reusing a single worker thread, which only needs to be created once and is repeatedly employed to play all the sounds This technique is known as thread pooling; a collection of worker threads is reused to process tasks as they arrive at the pool In our application, the pool only needs a single thread, which executes the sound-playing tasks in sequence Since J2SE 50, the creation of thread pools has been very simple, achieved with one of the static factory methods in Executors (a class in the javautilconcurrent package) We need ExecutorsnewSingleThreadExecutor(), which creates a pool holding a single worker thread (an executor) who carries out the tasks one at a time The thread pool, called soundExecutor, is created in the Obstacle constructor: // global private ExecutorService soundExecutor; // in the Obstacle constructor soundExecutor = Executors. add watermark text to pdf using itextsharp c# Add watermark to pdf using c# – Jak na PDF

C# demo to guide how to watermark PDF file, stamping text and image watermark to PDF document in C# language. When using inheritance to create variations or specializations of existing classes, all the properties and methods of the parent class are available to the child. You do not need to declare or define anything extra within the child class to be able to use properties and methods of the parent. This is termed encapsulation. The child class needs to contain definitions only for the properties and methods that are in addition to those of the parent. This test case has the advantage of leaving the original authenticate() method implementation intact, only overriding the findUser() method for the test. This works well for classes that have been refactored to isolate persistence operations, but these changes cannot always be made. The alternative is to mock the EntityManager interface. Listing 14-8 demonstrates this approach. Listing 14-8. Using a Mock Entity Manager in a Unit Test public class UserServiceTest2 { static final String USER_ID = "test_id"; static final String PASSWORD = "test_password"; static final String INVALID_USER_ID = "test_user"; @Test public void testAuthenticateValidUser() throws Exception { UserServiceBean service = new UserServiceBean(); service.em = new TestEntityManager(USER_ID, PASSWORD); User user = service.authenticate(USER_ID, PASSWORD); Assert.assertNotNull(user); Assert.assertEquals(USER_ID, user.getName()); Assert.assertEquals(PASSWORD, user.getPassword()); } @Test public void testAuthenticateInvalidUser() throws Exception { UserServiceBean service = new UserServiceBean(); service.em = new TestEntityManager(USER_ID, PASSWORD); User user = service.authenticate(INVALID_USER_ID, PASSWORD); Assert.assertNull(user); } class TestEntityManager extends MockEntityManager { private User user; newSingleThreadExecutor(); The playSound() method sends a task to the pool in the form of a Runnable object: // globals private String soundFnm; private SoundsPlayer soundsPlayer; private boolean isSoundPlaying = false;. If you are executing queries that return entities for reporting purposes and have no intention of modifying the results, consider executing queries using a transaction-scoped entity manager but outside of a transaction. The persistence provider may be able to detect the lack of a transaction and optimize the results for detachment, often by skipping some of the steps required to create an interim managed version of the entity results. Likewise, if an entity is expensive to construct due to eager relationships or a complex table mapping, consider selecting individual entity properties using a projection query instead of retrieving the full entity result. If all you need is the name and office phone number for 500 employees, selecting only those 2 fields is likely to be far more efficient than fully constructing 1,000 entity instances. add watermark text to pdf using itextsharp c# Windows 8 How to Watermark PDF in C# sample in C# for Visual ...
