After using the image processing software to process the picture, you need to choose a format to save. However, various formats are implemented at the bottom of the algorithm is not the same, this is suitable for the policy model. Write a program that demonstrates how to use a policy pattern to develop with a simple factory pattern combination.
Ideas are as follows:
1. Use interface to define an interface
pki-system access Policy
In the PKI system, in order to the security of the system, the various parts of PKI need to be divided into different regions, and the access strategy of the firewall is added to prevent the unnecessary service access system.
The large direction is divided into 3 regions:
1. KMC Area (intranet)
A) KMC server
b) KMC Database
c) Encryption Machine
2. CA Area (intranet)
A) Root CA server
b) level two CA server
c) CA
Proxy server is the function of network users to obtain network information, it is a transit point for network information. With the widespread use of proxy servers, a series of security issues followed. Because there is no access control policy for the proxy server to do a comprehensive and meticulous configuration, resulting in users can randomly access the proxy server to many pornographic, reactionary illegal sites, and these actions are often dif
Open the Internet option, enter the home page you want, remember not to click on the app. As shown in figure:

Then open Group Policy, navigate to the inside of the Disable Change home page settings, and turn this feature on.

The above is about using Group Policy to change your IE home page to force back . Make a decision
In the pro version, if you use the default Start menu style, the name of the user who is currently logged in to Windows is displayed at the top of the Start menu, which makes it easy for us to determine who is logged in as a single computer when multiple people share it. However, if this computer is only used by you, then the user name appears superfluous at the top of the Start menu, and we can use the Group Policy console to easily remove the Start

Today, when installing XNA with Win7, "system administrator set System Policy, prohibit this installation" appears, there are many methods on the Internet, one of which is:

primary key needs to be maintained by itself, and usually a separate table is required to store the current primary key value.
GUID typeThe GUID is the abbreviation for the globally Unique identifier, which is a 128-bit random number and is guaranteed not to produce duplicates.
Comb typeThe comb (combine) type can be understood as an improved GUID by combining GUIDs and system time so that it has better performance in indexing and retrieving things.

First, prevent access to the drive from My Computer (Windows 2000/xp/2003)
This policy makes it impossible for users to view the contents of the drive selected in My Computer or Windows Explorer. It also prohibits viewing directories on these drives using the Run dialog box, Mirror Network Drive dialog box, or dir command.

In the book "Java and Patterns" of Dr. Shanhong, this describes the strategy (strategy) Pattern: The policy mode belongs to the behavior pattern of the object. It is intended for a set of algorithms that encapsulate each algorithm in a separate class with a common interface, so that they can be replaced with each other. The policy pattern allows the algorithm to change without affecting the client.The st

PHP design pattern-rule pattern statement: This series of blog reference material "big talk design pattern", author Cheng Jie.
Policy patterns define a series of algorithms, encapsulate each algorithm, and make them replaceable. The policy mode allows algorithms to change independently of customers who use them, that is, encapsulate the changed algorithms.
Applicable scenarios:
1. multiple classes
Policy pattern is an important design pattern. Its main intention is to defineAlgorithmRespectively, so that they can be replaced with each other. It allows algorithm changes to be independent of algorithm customers, so that we can change them at any time without affecting the client'sCodeThe client can select different algorithms for execution.
To understand the policy model, we need to understand severa
