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:

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

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

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

4. Conditional SelectionUPDATE.
For example, the following update conditions are available:
For employees with a salary of more than 5000, the salary is reduced by 10%.
Employees with salaries between 2000 and 4600 increase by 15%
You can easily choose to execute two UPDATE statements, as shown below:

A topic is used to define visual styles for Web pages. A Topic consists of a series of elements: skins, CSS, images, and other resources. The subject can be applied to programs, pages, or server controls.
You can create a topic by adding the app_themes folder to the solution. You can also add the skin file to achieve the goal.
