Calculate the ThinkPHP nested loop by 40 minutes to print out the list of parent classes and child classes. Hello, I have been learning the thinkPHP framework recently. I want to print out a data list cyclically on the template page, the format is: first, the parent class category name, then print the corresponding subclass list, then print another parent class name, and then print the corresponding subclas
Understanding of CSS pseudo classes and understanding of CSS pseudo classes
Because I have never been familiar with css pseudo classes much before, and I can't understand a piece of css code on the Internet.

Currently, by querying the css manual, the css pseudo class only represents a State. a: hover only represents

Balon vernacular msdn: export C ++ classes from common DLL (2)-a closer look at the underlying mechanism of exporting C ++ classes in the previous article, we introduced how to export C ++ classes from a DLL and how to selectively export C ++ class members. So what is the underlying mechanism of the entire system? In what ways can we use the class exported from o
For Nested classes, see this article.
For more information about internal classes, see this article.
It is worth noting that
Static internal classes cannot access external non-static members (restricted by the non-static member access conventions of Java static members)
The internal class. Class file name format is as follows:

The relationship between classes (objects) 1, inheritance relationships C + + has multiple inheritance mechanisms. If you have a member variable of the same name in the two parent class of a class, it is more difficult to handle. 2. Realization relationship (class and Interface, polymorphic) 3, association relationship is the weakest relationship. An association relationship is an object in a class that has another class in its method. Life Example:
Os:windows7 x64Jdk:jdk-8u131-windows-x64Ide:eclipse Oxygen Release (4.7.0)Code One:Package cnblog.jizuiku.tool;//classes in other packages to access this class, you need to add a modifier to tools I add the maximum permissions Publicpublic class Tools {public static void SayHello () {System.out.println ("Hello World");}}Code two:/** does not pass the class between packets to access **/package Cnblog.jizuiku;class Demo {public static void main (string[
1. What if someone asks you if the interface in Java can be new? I think the answer should be yes, when implementing an anonymous inner class.http://blog.csdn.net/cntanghai/article/details/60944812. If someone asks you if the class can be modified by private, I think the answer is yes, one of the benefits of the inner class.1. internal classes can be very good to implement the hiddenThe generic non-intrinsic class is not allowed to have private and pr

After the first step, test to see if it compiles, and if not, compile manually:3, go to the Clean dialog, select Clean Projects selected below, then select OK4, the third step after the completion of the recompile test, if still cannot compile, that is the project set up a problem.

About the documents and views under MFC and the access to the framework, these issues have been commonplace, but I think there is no detailed description, special
Not for the poor English people, I looked at some blog, summed up a bit! I hope it helps people like me!One:1: Because for the SDI program, the main frame window is the Document box window (if this also do not know, it is necessary to look at MFC under the form of a single document principle).The following is about a single document.Ex
Most MFC developers are familiar with Open Database Connectivity (ODBC) database classes-they appear as early as 3.5. In MFC 4.2, there are some important improvements to these classes.
As a C + + developer, you may not be familiar with DAO because it is only available to Microsoft Access and visual basic® programming systems so far. If you are familiar with DAO, you must understand that DAO's implementati

Differences between abstract classes and interfaces
Abstract classes can contain non-abstract methods, and interfaces can only contain abstract methods.
Abstract classes cannot contain braces when declaring abstract methods, but all methods in the interface do not.Abstract class ):
