words.Therefore, in the spirit of saving, there has been the conversion of Unicode encoding to "Variable length encoding" UTF-8 encoding. The UTF-8 encoding encodes a Unicode character into 1-6 bytes according to a different number size, the commonly used English letter is encoded in 1 bytes, the kanji is usually 3 bytes, and only the very uncommon characters are encoded into 4-6 bytes . If the text you want to transfer contains a large number of English characters, you can save space with UTF-

DWZ internationalization is also relatively simple, the content of the site internationalization and the regular project internationalization is the same, do not make special adjustments.DWZ the internationalization of its own framework, such as the previous page of pages and the next page of information. This information is in the Dwz.frag.xml file, you can view it and understand.There are two ways to internationalize the framework.View Code1 Using multiple Dwz.frag.xml profiles, you can write
because this is two different objects.If Thread-1 accesses obj1,thread-2 access is also obj1, then Thread-2 will block because two threads are accessing the same object, but Thread-1 acquires the lock first, so Thread-2 must wait for Thread-1 to release the lock Before you can access it.For a static method, synchronized becomes a class lock, and for the scenario described above, the Thread-2 is blocked in both cases because the static method is shared by all objects of the class.Synchronized ca
threads according to the scheduling policy, and the calling thread's run () method gives the registered threads the opportunity to execute, and the dispatched program enters the running (Running) state. When the thread's run () method finishes running, the thread is discarded and enters the dead (Dead) state. You cannot call the restart () method to restart a thread that is in a dead state, but you can call each method of a thread object that is in a dead state. If the thread is in the running
Recently made an ATL-based control, designed an interface, want to return multiple parameters, but through JavaScript but can not get the return value, originally thought is the problem of their own interface, and later found on the Internet a lot to find that the original MSDN has a clear saying:JavaScript does not support passing parameters by reference. JavaScript would make copies of these variables and pass them by value when calling methods then take By-reference parameteRs. Thus, you cann
