event occurs on another object? Common Methods in VB and C # are as follows: VB button (command) Click Event: Sub commandementclick () C # button click event: void button#click (Object sender, eventargs E) This indicates that an event is a signal mechanism that automatically sends a notification to an object when an activity occurs. It is an external message sending interface defined by the object. If other objects are interested in the event, an event is registered for the eve

Introduction If you have seen the article on delegates and events in C #, I think you have a basic understanding of delegates and events. But those are far from the entire content of the Commission and the event, there are many places that are not involved. This article discusses some of the more detailed issues of delegates and events, including some of the frequently asked questions, as well as event accessors, exception handling, timeout processing, and asynchronous method calls. Why use eve

Monitoring SQL Server Transactional replicationIn general, we can use the Replication Monitor in SSMs to monitor replication. But we can't stare at it for 24 hours, and we have to use an automated way to monitor it. Microsoft provides system stored procedure DBO.SP_REPLMONITORSUBSCRIPTIONPENDINGCMDS in the distribution database to return the number of commands waiting on a subscription, as well as the estimated time required to post all these commands to subscribers. I created a job that runs ev

. Replication consists of publishers, distributors, and subscription servers: Publisher: The source server for the data, maintains the source data, determines what data will be distributed, detects which data has been modified, and submits that information to the Distributor. Distributor: The Distributor is responsible for transferring data from the Publisher to the Subscriber. Subscribers: Subscribers are copies of the publisher's data and receive ma

, which is the role of the distribution database to store data sent from the forwarding publisher. A Distributor supports multiple publishers, just as a newsstand can sell magazines from multiple publishers. Similarly, the distributor can be the same instance as the Publisher, as publishers do not sell their magazines directly through newsstand.Subscriber serverThe subscriber in Figure 2 contains a copy of the data published by the publisher. This cop

state), The other server is in the standby state of the business (that is, the standby state). The dual-host approach means that two different services are in the primary standby state (that is, the Active-standby and Standby-active states) on two servers respectively.We are mainly using the SQL Server 2005 subscription replication feature to implement a dual-machine hot standby, as shown in:SQL Server 2005 Subscription replication principleThe following overview is from Microsoft's official MS

: static weaving and dynamic weaving. Static weaving methods generally require extension of the compiler function. You can modify the code to be woven by modifying the bytecode (Java) or IL code (.. Net) method, directly add to the corresponding weaving point; or, we need to add a new syntax structure for the original language, and support AOP from the syntax. AspectJ [19] adopts this method. To implement AOP in this way, the code execution efficiency is high. The disadvantage is that the implem

Delegate:Function pointer function (C ++). Unlike C ++, function pointers only point to static methods. ,The so-called delegate is to call the delegate function directly in the delegate method of our definition number instead of calling the preset function method during execution, the subsequent work will become much simpler, and even increase the readability and maintainability of functions.Example: delegate void eatdelegate (string food) // delegate function,Concept of delegated chain:Eatdeleg

A simple example of the observer mode in the Python design mode. This article describes the observer mode of the Python design mode. We will share this with you for your reference. The details are as follows: The observer mode is a software design mode. A Topic object contains a series of observer dependent on it, which automatically notifies the observer of the change of the topic object and usually calls a method of each observer. This design mode is verySuitable for Distributed Event Processi

C # events (event)Theory:Event is basically a user action, such as keystrokes, clicks, mouse movements, and so on, or something that appears, such as system-generated notifications.An application needs to respond to an event when an event occurs. For example, interrupts.Events are used for interprocess communication.Events are declared and generated in a class by using a delegate event, and are associated with an event handler by using a delegate in the same class or other class.The class that c

Pull model is initiated by the consumer of the message, the initiative is held in the hands of consumers, it will be based on their own situation t

Replication is focused on data synchronization, it doesn ' t distribute entire database, but only distributes some part of the database like tables or views 。1,publisher Publishing ServerPublisher is a data source that provides replication database objects2,subscriber
