Code lens is a simple way to know what happens with the code. Here you could find an image with the number of references of a method or class. If you can't see the code lens please see this question: Missing CodeLens references count in VS 2015 Community edition

Intoduction Since Visual Studio 2005 can you make Intellisense Code Snippets. This allow you to generate some code just by typing one keyword and press two times the tab key. Using the code The XML code you need for make an Intellisense Code Snippet stands below: <?xml version="1.0"...

Once Wildfly is installed by unzipping the distribution, it can be started by running the standalone.sh script on the bin directory: $ ./bin/standalone.sh ========================================================================= JBoss Bootstrap Environment JBOSS_HOME: /mnt/storage/tools...

Sometimes you may want to have a lambda expression implementing more than one interface. This is mostly useful with marker interfaces (such as java.io.Serializable) since they don't add abstract methods. For example, you want to create a TreeSet with a custom Comparator and then serialize it and se...

The StringLength attribute specifies the minimum and maximum length of characters that are allowed in a data field. This attribute can be applied on properties, public fields and parameters. The error message must be specified on the ErrorMessage property on the attribute. The properties MinimumLeng...

Every collection view must have a Datasource object. The Datasource object is the content that your app will display within the UICollectionView. At a minimum, all Datasource objects must implement the collectionView:numberOfItemsInSection: and collectionView:cellForItemAtIndexPath: methods. Requir...

When you request the url yourSite/Home/Index through a browser, the routing module will direct the request to the Index action method of HomeController class. How does it know to send the request to this specific class's specific method ? there comes the RouteTable. Every application has a route ta...

Hibernate (and embedded H2 DB) <?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/...

We can create empty thread objects and assign work to them later. If we assign a thread object to another active, joinable thread, std::terminate will automatically be called before the thread is replaced. #include <thread> void foo() { std::this_thread::sleep_for(std::chrono::seco...

To obtain a reference to a KClass object representing some class use double colons: val c1 = String::class val c2 = MyClass::class

The conventional connect syntax that uses SIGNAL and SLOT macros works entirely at runtime, which has two drawbacks: it has some runtime overhead (resulting also in binary size overhead), and there's no compile-time correctness checking. The new syntax addresses both issues. Before checking the synt...

Given that the 8086/8088 was used in the IBM PC, and the Operating System on that was most often from Microsoft, Microsoft's assembler MASM was the de facto standard for many years. It followed Intel's syntax closely, but permitted some convenient but "loose" syntax that (in hindsight) onl...

Intel wrote the specification of the 8086 assembly language, a derivative of the earlier 8080, 8008 and 4004 processors. As such, the assembler they wrote followed their own syntax precisely. However, this assembler wasn't used very widely. Intel defined their opcodes to have either zero, one or tw...

Although the 8086 was most used in IBM PCs along with Microsoft, there were a number of other computers and Operating Systems that used it too: most notably Unix. That was a product of AT&T, and it already had Unix running on a number of other architectures. Those architectures used more convent...

Borland started out with a Pascal compiler that they called "Turbo Pascal". This was followed by compilers for other languages: C/C++, Prolog and Fortran. They also produced an assembler called "Turbo Assembler", which, following Microsoft's naming convention, they called "T...

When the GNU project needed an assembler for the x86 family, they went with the AT&T version (and its syntax) that was associated with Unix rather than the Intel/Microsoft version.

NASM is by far the most ported assembler for the x86 architecture - it's available for practically every Operating System based on the x86 (even being included with MacOS), and is available as a cross-platform assembler on other platforms. This assembler uses Intel syntax, but it is different from ...

YASM is a complete rewrite of NASM, but is compatible with both Intel and AT&T syntaxes.

Suppose that you have a pointer to an object of a polymorphic class: Shape *ps; // see example on defining a polymorphic class ps = get_a_new_random_shape(); // if you don't have such a function yet, you // could just write ps = new Square...

A content script is extension code that runs alongside a normal page. They have full access to the web page's DOM (and are, in fact, the only part of the extension that can access a page's DOM), but the JavaScript code is isolated, a concept called Isolated World. Each extension has its own content...
