Character set and proofing rules1. Character set: A set of symbols and character encodings.2. Proofing Rules: A set of rules that are used to compare characters within a character set. 3, the installation of the database is best with our fixed code.4. You can specify a character set when you create a table: ..... Charset=[gdk/utf8] ;5. View the coded variables:show varchar like '%char%';–character_set_serv

L "Rule 3-1-8" uses the correct set of antonyms to name a variable with a mutually exclusive meaning or a function of the opposite action. For example: int minvalue; int maxValue; int SetValue (...); int GetValue (...); 2 "recommendation 3-1-1" to avoid the number of names, such as Value1,value2, unless the logic does need to number. This is to prevent programmers from being lazy and refusing to name their brains to cause meaningless names (because it's the easiest to use numbers). 3.2 Si

similar, which starts with a double underscore, and ends with a double underscore, which is a special variable that __xxx__ can be accessed directly, not a private variable, so __name__ __score__ the variable name cannot be used.There are times when you see an instance variable name that starts with an underscore, such as an _name instance variable that can be accessed externally, but, as you see in the rules, when you look at a variable like this, t

The scope resolution of Python is based on rules called LEGB (local), enclosing (closed), Global (global), built-in (built-in)). This looks very intuitive, right? In fact, there are some subtle places in python that are prone to error. See this example:12345678910>>> x = 10>>> def foo ():... x + = 1... print X...>>> foo ()Traceback (most recent):File "File "unboundlocalerror:local variable ' x ' referenced before assignmentWhat's going on?This is beca

Many times we have used anti-virus software to find their own machines such as backdoor. rmtbomb.12, trojan.win32.sendip.15 and so on these a string of English also with digital virus name, at this time some people on the Meng, so long a string of names, how do I know what the virus ah? In fact, as long as we know some of the virus naming rules, we can use the anti-virus software report in the virus name to determine the virus some of the public

1. Use Pascal casing rules to name methods, types, structs, interfaces, delegates, enumerations, enumeration items, properties, events, and so on. public class DataGrid {　 　　　　　　　　　 public void DataBind() 　　　　　　　　　 { 　　　　　　　　　 } } 2. Name all variables, fields, and parameters with the Camel case rule. Pascal can also be used camel case rules: constants, control IDs. public class Product { 　　　　　　　　　 priv

Variable naming and code conventions are often a difficult topic in a project, and programmers tend to use their personal naming conventions rather than others to prescribe how they write code. However, having universal naming conventions is valuable when code needs to be read by other members of the team (especially when code is checked), and having a common naming convention makes it easier for you to read your code later. This experience after several projects, Experience more deeply. That

Regular Expressions-match rules the basic pattern matches everything from the very basic to the beginning. Patterns, which are the most basic elements of regular expressions, are a set of characters that describe the character of a string. Patterns can be simple, consist of ordinary strings, or can be very complex, often with special characters representing a range of characters, repeating, or representing context. For example: ^once This pattern cont

Write in front The experimental reference The pox script sets the controller's forwarding policy, so just understand the script. The Mininet script sets up the topology and related information, so just understand the script as well. Pox scripts are not understood at the moment.
