interface, where the interface is very simple, that is, to implement the method of creating the ILogger interface, the code is as follows:
Public interface Iloggerprovider
{
ilogger createlogger (string name);//Create a Ilgger instance of a given category
}
and the implementation of ILogger is relatively simple, in addition to the implementation of common logging methods, but also need to implement a log-level judgment method and a scope creation method, interface definition is as
id = 1 and ord (mid (password )) = 49 (verify the First password)Union select, 1 from ymdown_user where id = 1 and ord (mid (password )) = 50 (second digit)Union select, 1 from ymdown_user where id = 1 and ord (mid (password,) = 51........................................ ..........................
Example 2: gray track transformation id test (meteor)Union % 20 (SELECT % 20 allowsmilies, public, userid, 0000-0-0, user (), version () % 20 FROM % 20calendar_events % 20 WHERE % 20
.
Then there is the opposite of the aggreger. The aggreger must inherit the abstractreceiver class and override the onevent method:
public class MyEventReceiver extends AbstractEventReceiver{...@Overridepublic void onEvent(int eventId , EventBase event){if (eventId == EventIds.EVENT_PAGE_START) { ... } } }
Yes, the onevent method is the operation to be triggere

The second method is to use an HTML template to generate an HTML page. The template contains the corresponding tag, which can be used to retrieve data from the database and other places. Fill in this tag to generate an HTML page, this method is useful in many news systems.

It is such a simple structure that I did not expect any problems.
The source name I used during the test is "mysource" and the created log is "mylog". Everything works normally;However, when the client is actually running, the log name is set to "toollog" due to the customer's requirements. As a result, an exception is thrown when the log is written in step 2:

The Enterprise Library of Enterprise Library does not provide an SQL script to record logs to the Oracle database. To enable logging to the Oracle database, write the following script:

In this example, the reflection provider is used, information see msdn: http://msdn.microsoft.com/en-us/library/dd723653 (vs.100 ). aspx. You can also customize a provider.

1. High Performance (this framework uses a pure ADO. NET Framework to avoid performance loss caused by Linq and reflection );
2. ease of use (simple configuration, SMART awareness, and assistance from code generators, and SQL (self-performance optimization ));
3. multi-database support (the entire framework is designed in factory mode. Currently, it supports oracle, mssql, mysql, sqlite, and acess. If necessary, it can be expanded by itself)
4. New query functions (write code like linq)

Twitter storm tracks messages, guaranteeing "at least one" message processing semantics:
All events emitted by the data source (the first node of the processing diagram) are marked with a random EventID. The framework maintains a set of [Eventidàsignature] key-value pairs for each data source's initial event. Among them, signature is initialized with EventID.
After the initial event is received by th
