On the Practice of this attempt after the last article (http://www.cnblogs.com/Ivan-Yan/archive/2008/10/29/1322119.html), got a few friends (wood wild fox (Neil Chen), T2, etc.) guidance, thank you again for your enthusiastic help. ThoughtsAfter restructuring the warehouse receiving of different products in a simple factory model last time, as friends said, this design is indeed not flexible: if there is a new product (such as raw materials) warehouse receiving operation, there are too many ch

queue The queue is characterized by first-in-first-out, append () is used to route an object to the end of the team, and pop (0) is used to pull the first object 3. Functional programming tools For linked lists, three functions are very useful: (1) filter (function, list) This function is a filter function that returns all element linked lists in the list that return true after the function operation. For example: Code highlighting produced by Actipro CodeHighlighter (

Objects in javascript can be created in the following ways: (1) Using built-in objects (2) using JSON symbols (3) user-defined objects (1) Using built-in objects JavaScript built-in objects can be divided into two types: 1, javascript native objects (Language-level objects), such as string, object, and function. 2. Host objects during Javascript Runtime (Environment host-level objects), such as Windows, document, and body. The built-in object is used to construct a new object through the constru

To implement an ActiveX control using C #, three problems must be solved: 1. Enable the. NET component to be called by com 2. After registering on the client, ActiveX control can pass IE Security Authentication. 3. When the client is not registered, the installation package can pass ie signature authentication.

I didn't plan to write this article, but everyone knows the importance of the file. In device I/O, a device is called a file device. This is an abstract concept. You just need to understand it as a file. File device, which can be opened through the createfile function to obtain a file object handle. There are two important attributes in the file: 1. file size: the maximum size of a 32-bit file is 4 GB, and the size of a 64-bit file can reach 16 EB. 2. file read/write pointer: This pointer indic

There are many types of linked lists in the Linux kernel. If each type of linked list is represented by a separate data structure, you need to implement a set of primitive operations for each linked list, including initialization, insertion, and deletion. Therefore, the Linux kernel defines an interesting data structure: list_head Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--> Struct List_head {

WPF comes with a WebBrowser control. When we use it to open a webpage, such as Baidu, and then click a link in it, a new window will pop up, then it will pop up an IE window instead of jumping to the link internally. If you use the WebBrowser control of Winform, we can listen to its NewWindow event and perform some processing in this event. For example, when you create a new Tab to open it, you can also control the redirection in the current WebBrowser. Unfortunately, the WPF WebBrowser does not

The use of export and import in MEF is essentially the process of instantiating an object. Through the features of MEF, the direct dependency of the object is reduced, this allows the system design to achieve a highly flexible and scalable effect. In specific design and development, some objects do not need to be instantiated during system running or affiliated object initialization, it is instantiated only when it is needed. In terms of the system, this is also a feasible way to improve the sys

Connection: http://www.cnitblog.com/CoffeeCat/archive/2008/02/25/40138.html Javascript itself does not support object-oriented features. It does not have an access control operator and does not define the class keyword. It does not support inherited extend or colons, nor does it support virtual functions, however, Javascript is a flexible language. Let's take a look at how Javascript without a keyword class implements class definition and creates objects. I. Define a class and create an instance

The root of as3 is that the top-level container is stage, and stage is the only instance of Stage class. When you create a document, you create a stage instance. The root mentioned above is a visual instance in stage.Because both stage and root are containers, when you write code on the timeline, you can have two options to add objects under stage or root. We first write the code in the timeline: Code highlighting produced by Actipro CodeHighlighter (freewa
