go message widget

good way to implement the view update for a view component that is not thread-safe.So how does a child thread put the message into the message queue of the main thread? As long as the handler object is created with the looper of the main thread, when the SendMessage method of handler is called, the system puts the message queue of the main thread of the

Introduced Moonmq is a high-performance Message Queuing system implemented with go, and is ready for use in our messaging push service and asynchronous tasks in various backgrounds. In the design above, Moonmq mainly borrowed rabbitmq and rocketmq related ideas, but did a lot of subtraction, after all, I am not designed to be

! Anyway, this interface doesn't have a problem.The queue's handling of the load balance is perfect. For multiple consumer, RabbitMQ is sent to different consumer in a balanced Way (round-robin).4.4 ExchangesAs you can see from the architecture diagram, Procuder Publish's message entered Exchange. Then through the "Routing keys", RABBITMQ will find out which queue the message should be placed in. The queue

MSMQ implements the principle that the sender of a message places the information he wants to send into a container (what we call a message) and then saves it to a message queue in a system's public space A local or offsite message receiver is then taken out of the queue to process messages sent to it.I personally unde

These days the company is relatively empty, and began to play Go language, found it can be written through a https://github.com/lxn/go-winapi go-winapi library windowsProgramSo it began to play, of course, there is a lot of it based on further encapsulation for development projects, such as https://github.com/lxn/walk.

response. Our code is quite simple and does not attempt to solve more complex and important problems, such as: What does the client need to do if no server is running? Should RPC set a timeout mechanism? If the server runs out of error and throws an exception, do you need to forward the problem to the client? Do you need a boundary check?

MFC can generally use the ClassWizard Class Wizard to add message and message processing functions, but the user-defined message must be entered manually, now the VC custom message method steps are recorded as follows:(1) Define a message that uses the # define statement to

stage. To ensure the efficiency of message delivery and execution, the system caches the memory addresses of all selector and used methods. Each class has a separate cache that contains the current class's own selector and the selector inherited from the parent class. Before the dispatch table (Dispatch table) is found, the message sending system first checks the receiver object's cache. In the case of cac
