mode mainly includes three roles: factory class, abstract class (Interface), and specific class.The interface is as follows:Namespace Xiaoxue
{
Public interface iMessage
{
Void sendmessage (Object MSG );
}
}
The factory type is as follows:Namespace Xiaoxue
{
Public class messagefactory

Public static iMessage createmessage (string type)

the method of the real target object is called only in the last part, we can "hijack" the call in the middle so that it can call our CallHandler first. The breakthrough of such Inject lies in RealProxy. In FCL (Framework Class Library), RealProxy (System. runtime. remoting. proxies. realProxy) is a special Abstract Class. You can inherit from RealProxy to define your own Custom RealProxy and write the operations you need to inject into the Invoke method. PIAB adopts such a solution.

Flash implementation
Previous articles have introduced how beetle uses protobuf.net for Object serialization data transmission. This chapter describes how beetle uses fluorinefx and flash for amf3 communication. the implementation principle is the same as that of protobuf.net. You can extend a messageadapter.
The implementation of messageadapter is as follows:

I wanted to use Ninject for a while and then searched for a long time. I didn't find any details about how to use Ninject, so I just wrote a few articles about Ninject.

The above section discusses the class factory/object lookup service, this section talks about the implementation of AOP.AOP is the abbreviation of Aspect oriented programming, which means: face-cutting programming, through the pre-compilation method and run-time dynamic agent implementation of the unified maintenance of the program functions of a technology.Netop.core's AOP uses the proxy implementation. With proxy, your class must inherit a base class (not the default object, of course, if your
After seeing zuola, I got a wordpress Trojan script. So I clicked the connection and simply looked at the sample. The principle is relatively simple. First, determine whether the access source is a search engine spider or bot, and then determine whether a problematic iframe-the effectiveness of the Trojan depends on the content in the iframe. This short PHP script can be used completely.

Overview
In recent years, Peer-to-peer technology has been used frequently, worms and has more and more become. The p2p-based botnet is very hard to trace and to shut down, because the botnet has robust, network connectivity, uses ENCR Yption, and controls traff
Use AOP to write 2 PC frameworks (I), and use aop to write 2 PC frameworks
I don't really want to write this series, because this 2 PC is a little tricky to write a small architecture separately. But I don't know what to write. Let's write it first.
The entire process is as follows:
There are many articles about the AOP series. I will repeat them here.
First, we define an IAopProxy interface used to create a Proxy instance for AopProxyFactory. The Code is as follows:Public interface IAopProxy {
only supports processing iMessage objects, you must implement an iMessage for protobuf-net serialization. The serialized information of protobuf-net is closely related to the object content that does not include the object type information. Simply put, protobuf-net cannot deserialize the object based on the serialized information, in the deserialization process, the data must be explicitly specified based
Advice notification method. The IAspect method of Websharp AOP defines the PreProcess and PostProcess methods to support Before and After notifications. IAspect is defined as follows:

The example provided by aspectsharp provides a simple logger interceptor and a persistent mixer. Let's take a look at its working principles.

to iclientchannelsinkprovider? Unfortunately, the answer is no. Can we insert a messagesink through iclientchannelsinkprovider? Can it play its role after being inserted?
First, implement a custom messagesink. In this case, you only need to create a new class and implement the syncprocessmessage method in the imessagesink interface (for the sake of simplicity, we only need to consider synchronous call mode). In the method, we can directly operate the message object, for example, we can add addi
. Semi-query (only sequential series can be searched)
Basic Idea: set N orders (from small to large) to be stored in array a [1] ---- A [n]. The number to be searched is X. Use the variables bot, top, and mid to indicate the bottom (lower-bound array), top (upper-bound array), and center of the data range, mid = (top + BOT)/2, respectively, the half-lookup algorithm is as follows:(1) x = a (MID), the exit l
