In C + +, there are many ways to use synchronization across processes, but in C # there is less programming across processes, and more other mechanisms are used, especially as the technology of WCF as a distributed programming is becoming more and

events in C # Reference books: "C # Diagram Tutorial" This thing, in fact, is the observer pattern. Events are in many frameworks, such as ANDRIOD,QT5 (signal slot), Cocos2d-x,unity3d, general GUI such as buttons, editing text, and so on, which

One, definition.A pure virtual function is a virtual function declared in a base class that is not defined in a base class, but requires that any derived class define its own implementation method. The way to implement pure virtual functions in a

A long, long time ago ... In a class there are variables, attributes, methods, in fact, there can be delegates (also known as proxies), there are events, like the button class has name, GetValue (), there is a click Delegate: Delegate return type

The understanding of Delegates in C # (easy for Java children to understand) Definition: A delegate is an abstract method in Java, a method that is not implemented, without a method body. To know exactly what part of the code it is running when the

Static_assert: This macro is used to detect and diagnose compile-time errors. Compile-time, which is a macro that is the opposite of Crt-assert (run-time macro). This good thing is used to detect the invariants of a compile-time program. This

A function that uses C + + to generate different random numbers rand () is supplemented by the Srand () function to generate 54 digits between 0~53 (54 is chosen because of the shuffle) Algorithm one: To first define an array (which can be all 0 or

Today I happened to look at the new features of c#4.0, the first new feature I was excited about, once I used C # is not accustomed to the "dead parameter" problem has finally been done.It's really cool! Used to use C + +, VB. NET when all very cool,

View Matrix Also known as the camera matrix, it is composed of three parts, namely, the camera position, the target position and the camera up and down direction. In DirectX, a method is provided to form a view matrix through these three parts, all
