First, download a copy of SFML from the official page. Save it anywhere in your computer where it can be easily accessed. Open Codeblocks. Go to Project->Build Options->LinkerSettings tab. Click on the Add button and go to the bin folder of SFML and select all the files present there...

To convert String to and from Data / NSData we need to encode this string with a specific encoding. The most famous one is UTF-8 which is an 8-bit representation of Unicode characters, suitable for transmission or storage by ASCII-based systems. Here is a list of all available String Encodings Stri...

To make a new directory from a File instance you would need to use one of two methods: mkdirs() or mkdir(). mkdir() - Creates the directory named by this abstract pathname. (source) mkdirs() - Creates the directory named by this abstract pathname, including any necessary but nonexistent parent d...

Returns the starting position of the first occurrence of a the specified pattern in the specified expression. Parameters: pattern. A character expression the contains the sequence to be found. Limited to A maximum length of 8000 chars. Wildcards (%, _) can be used in the pattern. If the patter...

NgZone reference can be injected via the Dependency Injection (DI). my.component.ts import { Component, NgOnInit, NgZone } from '@angular/core'; @Component({...}) export class Mycomponent implements NgOnInit { constructor(private _ngZone: NgZone) { } ngOnInit() { this._ngZone.runO...

runOutsideAngular can be used to run code outside Angular 2 so that it does not trigger change detection unnecessarily. This can be used to for example run multiple HTTP request to get all the data before rendering it. To execute code again inside Angular 2, run method of NgZone can be used. my.com...

Repeats a string value a specified number of times. Parameters: string expression. String expression can be a character string or binary data. integer expression. Any integer type, including bigint. If negative, null is returned. If 0, an empty string is returned. SELECT REPLICATE('a', -1) ...

public void ConfigureServices(IServiceCollection services) { services.AddMvc(); services.AddCors(); services.ConfigureCors(options => options.AddPolicy("AllowSpecific", p => p.WithOrigins("http://localhost:1233") ...

Definition of the category The Haskell types along with functions between types form (almost†) a category. We have an identity morphism (function) (id :: a -> a) for every object (type) a; and composition of morphisms ((.) :: (b -> c) -> (a -> b) -> a -> c), which obey category la...

Categorical products In category theory, the product of two objects X, Y is another object Z with two projections: π₁ : Z → X and π₂ : Z → Y; such that any other two morphisms from another object decompose uniquely through those projections. In other words, if there exist f₁ : W → X and f₂ : W →...

This example is not tied to any concrete GUI toolkit, like reactive-banana-wx does, for instance. Instead it shows how to inject arbitary IO actions into FRP machinery. The Control.Event.Handler module provides an addHandler function which creates a pair of AddHandler a and a -> IO () values. Th...

In reactive-banana the Event type represents a stream of some events in time. An Event is similar to an analog impulse signal in the sense that it is not continuous in time. As a result, Event is an instance of the Functor typeclass only. You can't combine two Events together because they may fire a...

To represent continious signals, reactive-banana features Behavior a type. Unlike Event, a Behavior is an Applicative, which lets you combine n Behaviors using an n-ary pure function (using <$> and <*>). To obtain a Behavior a from the Event a there is accumE function: main = do (...

When applied to a property of a domain class, the database will create a NOT NULL column. using System.ComponentModel.DataAnnotations; public class Person { public int PersonID { get; set; } [Required] public string PersonName { get; set; } } The resulting column wi...

[MaxLength(int)] attribute can be applied to a string or array type property of a domain class. Entity Framework will set the size of a column to the specified value. using System.ComponentModel.DataAnnotations; public class Person { public int PersonID { get; set; } [MinLength(...

Title This band is showed once at the beginning of the report. It can be used as first page by setting the attribute isTitleNewPage="true" Page Header This appears at the beginning of each page excluding first page if Title band is used and last page if Summary band is used with setting...

.jrxml is the report design file, it's format is in human readable XML, it can be complied into a JasperReport object and saved as a .jasper .jasper is the compiled version of the .jrxml and can be loaded directly into a JasperReport object ready to be filled with data .jrprint is the se...

The Collection object implements the ArrayAccess and IteratorAggregate interface, allowing it to be used like an array. Access collection element: $collection = collect([1, 2, 3]); $result = $collection[1]; Result: 2 Assign new element: $collection = collect([1, 2, 3]); $collection[] = ...
