In this first article, we need to know about reverse Ajax, polling, streaming, Comet, and long polling ), learn how to implement different reverse Ajax communication technologies and explore the advantages and disadvantages of each method. You can download the source code of the example in this article.

Number token >>> Continue Part 1 From this small example, we can see the following key points: The scanner scans and skips the blank characters (such as spaces) between tokens ). When this operation ends, the current character is definitely not a blank character. The non-null character determines the next token type to be extracted and becomes the first character of the token. The scanne

you often use a system, it is often in a fixed usage mode. Sometimes, you do not get into the habit of doing things in the best way possible. Sometimes, your bad habits may even lead to confusion. One of the best ways to correct such defects is to consciously adopt the good habits of resisting these bad habits. This article presents 10 UNIX Command Line habits worth using-a good habit of helping you overcome many common usage quirks and improve the efficiency of command line work in this proces

Although the file is misplaced, this example highlights the importance of protecting the file system for attackers.If the PHP application processes the file at will and contains variable data that can be entered by the user, check the user input carefully to ensure that the user cannot perform any inappropriate operations on the file system.

CONNECT Oe/oe; CREATE TABLE Nfresults ( Operdate DATE, Tblname VARCHAR2 (60), Rslt_msg VARCHAR2 (100) ); In practice, you may need to create more tables to record information such as notification events and row IDs for the rows that are changed, but for this article, the Nfresults table is perfectly up to suit. Using Utl_http to send notifications to clients You may also w

In the actual project development, there will be many objects, how to manage objects efficiently and conveniently, and become an important link that affects program performance and maintainability. Java provides a collection framework to solve such problems, linear tables, lists, hash tables, etc. are commonly used data structures, in the Java development, the JDK has provided us with a series of corresponding classes to implement the basic data structure, all classes in Java.util this package,

1 files and directories of Linux Modern operating systems introduce files for long-term storage of information that can be stored independently of the process, and the logical units of the files that create information as processes can be used concurrently by multiple processes. In UNIX systems, the operating system designs a common set of APIs for I/O operations such as text and images on disk, input devices such as mouse and keyboard, and network interaction, so that they can be used to unifo

consider encoded source code forms that allow for many different lexical formats: the order of the attributes is not specified, and the rules for the use of whitespace characters between the element names and their attributes are flexible, And there are many different ways to represent characters and escape special characters. Namespaces also bring greater lexical flexibility (such as whether using prefixes is optional). The result is that you have many documents that are exactly equivalent to

If only one way to use the database is correct, you can create database design, database access, and database based PHP business logic code in a number of ways, but the end result is usually a mistake. This article describes the five common problems that arise in the database design and the PHP code that accesses the database, and how to fix them when they are encountered. question 1: Use MySQL directly A common problem is that older PHP code uses the MYSQL_ function directly to access the dat

developing applications, so using IBATIS without any external dependencies is actually a big advantage. (Note that some optional configurations allow the use of external connection tools or byte code enhancements, but these are not required.) ） It is time to delve into some of the more specific IBATIS concepts and semantics that will eventually lead us to some encodings and examples. The semantics of Batis Data Mapper The remainder of this tutorial looks at the Data Mapper framework in a near-

addition to allowing your implementation to be hidden after a change, using a public access method rather than directly exposing the field will allow you to build on the base implementation, by overriding the implementation of the access method to perform a slightly different behavior from the parent method. It also allows you to build an abstract implementation that delegates the actual implementation to the class that overrides the basic implementation.bad habits: exposing public fields In th

example, it can find a query that does not use the MySQL index, so if you forget to index an important column and cause a performance problem, you will be able to easily find this column (for more information on MySQL indexes, see Resources). This plugin displays all such information in a pop-up Finally, don't forget to use tools like Firebug, YSlow, Ping, and tracert to detect whether a performance problem is from a network or a resource-loading problem. Next, let's look at some specific Ra

The Application of functional concepts includes extended array sorting, beautiful code generated by Dynamic HTML, and applications of series functions.

). If you want to find the names of all contacts for the company, but type "lsdevelopment company" (for example), no matching names will be found. There are multiple methods for more accurate input keys (such as drop-down lists), but for ease of discussion, assuming that @ dblookup returns an error even if strict development techniques are used. The basic method for error check is to compile the code shown in Listing 1:

eliminating page loading. To demonstrate this, I use a simple shopping cart example, which will be dynamically updated when a project is added to it. If this technology is integrated into online stores, users can continuously browse and add projects to the cart without waiting for complete page updates after each click. Although some code in this article is specific to the shopping cart example, the demonstrated technology can be applied to any Ajax application.

Java class Java classes are provided to form a simple Web Service Java project. You can also use the Java class you created. The project used in this article contains three types:OneWayRequestClass,TwoWayRequestClass andTwoWayResponseClass. Look at each class in order. Let's start fromOneWayRequestClass (see Listing 1 ).
