Pint:^string: Before you put the ^ in the data type, the description is the type of the declared string pointer!If you want to remove the value referenced by the pointer, put the ^ on the declared type, for example: pint^If you want to take the referenced address of the Pint type, you can put the @ before it, for example: @Pint^type indicates pointers to this typepoint^ returns the value of the variable pointed to by the pointerThe meaning of Delphi ^

Using Get,set can make the class definition more canonical, because, normally, if we write a custom class, his property is either public or private, but if the properties of public are to be restricted, such as a person's age does not allow negative numbers, nor is it allowed to be greater than 150, Then you are only limited to the int type is not enough. A person's name does not allow less than two characters and does not allow more than 5 characters, then you are only limited to string is not

still gains control of the CPU and may be replaced by another thread to gain control of the CPU. This is also what we often write in cycle Thread.Sleep (0), because this gives other threads such as the paint thread the power to gain control of the CPU, so that the interface will not feign death there.In addition, although it is mentioned above that "unless it itself abandons the CPU, it will completely occupy the CPU", but this behavior is still constrained-the operating system will monitor the

Recently in the study of cocos, the Internet industry, hand tourism recent performance is a very fire, coupled with its own interest in the game, so they have to meddle in the game engine ~This time the nonsense is so short, because the record of the things itself is very few.In cocos, adding a cache for Sprite frames can be done in the following wayCc.spriteFrameCache.addSpriteFrames (URL, texture)Where the first parameter is a plist or JSON file path, the second parameter is a texture picture

Format-detection translated into Chinese means "format detection", as the name implies, it is used to detect some of the HTML format, the Format-detection property about meta is mainly the following settings: Meta name= " Format-detection "content=" telephone=no "meta name=" format-detection "content=" email=no "meta name=" format-detection "Content=" Adress=no "can also ligatures: Meta name=" format-detection "content=" Telephone=no,email=no,adress=no "below specifically the role of each settin

the right red and green blue, so red and green blue is also known as the three primary colors, each primary color is stored the value of the information expressedTo be blunt is actually:Alpha_8 is that Alpha is made up of 8 bits .argb_4444 is made up of 4 4-bit, or 16-bit,argb_8888 is made up of 4 8-bit, or 32-bit,rgb_565 is R is 5 bits, G is 6 bits, B is 5 bits total 16 bitsThus:Alpha_8 represents a 8-bit alpha bitmapargb_4444 represents a 16-bit ARGB bitmapargb_8888 represents a 32-bit ARGB b

specific values. For example: Android: textcolor = "? Android: textdisabledcolor" Note that this is very similar to resource reference, except that we use "? "Prefix replaces "@". When you use this tag, you provide the name of the property resource, which will be searched in the topic, so you do not need to display the Declaration type (if the Declaration, the form is? Android: ATTR/Android: textdisabledcolor ). Besides using the resource identifier to query the value in the topic instead of th

The meaning and function of PTR in assembly language MoV ax, BX; is to assign the value of the Bx register "in" to ax, because both are word type, so there is no need to add "word"MoV ax, word PTR [BX]; is the data stored in the place where the memory address is equal to the value of the Bx register, and is assigned to ax. Because we only provide a memory address and do not know whether it is byte or word that we want to assign to ax, we need to us

Understanding the meaning of @ class in objective-C In objective-C, when a class is used to another class and the referenced pointer needs to be created in the Class header file, The following code is used: A. H file C code # Import "B. H" @ Interface A: nsobject { B * B; } @ End For the sake of simplicity: Class A is a reference class, and Class B is a referenced class. The implementation file of Class A is not considered here. There are

difficult, several other CPUs with independent intellectual property rights even have no chance to survive, not to mention the so-called experts, over the past few years, college students in the Microelectronics curriculum can compile their own instruction sets through the open source code on the Internet. Is it useful? 5. Where is the significance of godson? Some people say that since the industrialization of the dragon core is very difficult, since the dragon core is unlikely to replace intel

Zheng20080712 Answer a user's question. Semantics is a difficult journey. Meaning, only some specific things can be done,AlgorithmThe accuracy rate is limited. It takes a lot of time and patience to increase the accuracy. However, it is a space without a ceiling. There is a lot of water in it. Global experts like the cloud, but once they enter, they will not be capped, and there is great room for development. It is d

different platforms, however, most implementations are related to various platforms. Since each C compiler has many differences and subtle differences in C support and understanding, it has ansi c; ansi c (subjective intention) it specifies the specific meaning of each element of C language and compiler implementation requirements in detail, introduces a new function declaration method, and sets up the standard form of standard library. Therefore, th

Use strace to see:1. Command> file 2> 1The key System Call Sequence for implementing redirection in this command is:Open (File) = 3Dup2 (3, 1)Dup2 (1

Linux Kernel and some other open-source code often encounter such code: do{ ...}while(0) Such code is not a loop at first glance. Do... while has no meaning at all on the surface, so why should we use it like this? In fact, do {...} while (0) is much more effective than beautifying your code. I checked some information and summarized the following advantages: 1. Help define complex macros to avoid errors when referencing: For example, s

testsequence print_any B1 Match with is really powerful, especially when the set is used as a branch. however, this is misleading, that is, the head above. Tail is not the header and bit in the linked list we understand. It is actually a placeholder symbol here. of course, this is because of the symbolic name, and the head and tail of the list are misleading: let listOfList = [[2; 3; 5]; [7; 11; 13]; [17; 19; 23; 29]] let rec concatList l = match l with | head :: tail -> he

Meaning of make mrproper and mrproper Before compiling a project in Linux, make mrproper is usually used to delete the files and configuration files generated before compilation and backup files. The differences between mrproper and distclean and clean are as follows, the makefile in the root directory of the Linux kernel source code has a clear explanation:Help:@ Echo 'cleaning targets :'@ Echo 'clean-remove most generated files but keep the config a

This article provides a detailed analysis of the differences between VC6X86 and VC9X86 in PHP and the meaning of NonThreadSafe. For more information, see PHP 5.3.0, however, there are several different versions available for download. That is, VC6 X86 and VC9 X86. First, let me answer: What is VC6?VC6 is compiled by the legacy Visual Studio 6 compiler. What is VC9?VC9 is the Visual Studio 2008 compiler, which is compiled by Microsoft VS editor.So

As ruby is a pure object-oriented language, everything is an object. methods are objects and classes are objects ..., therefore, self has many environments. Only by distinguishing the meanings of self in different environments can we better understand the meaning of the program.I. Top Level ContextRuby codePuts selfPrint out main, which indicates the default Object main.2. In the definition of class or module:In the definition of class and module, sel
