Due to the emergence of. net, a lot of development work has indeed become more advanced languages like English. Due to the object-oriented development and design, a lot of originally complicated operations are only involved in component development. For the front-end application layer, you only need to call attributes and Methods one by one. For example, to add a Document, first declare a Document object named doc, and then assign a value to the Document attribute:
Doc. Name = "test ";
Doc. File

Recently, when I was writing an Instant Messaging Server, I encountered a dilemma about session design in communication protocols.
First, let's talk about some existing protocol designs:
1. MSN, sip, fetion (SIP)
In this Protocol, both parties need to establish a session. First, a session creation request is sent. The following uses a sip conversation as an example:
First, send an invite to the server, and then receive the OK message to
basic. Consume command. In this way, the channel is set to the receiving mode until the queue subscription is canceled. After subscribing to a message, the consumer can automatically receive the next message from the queue (available) after consuming (or rejecting) The message recently received.In this subscription mode, after the producer publishes a message to the queue, the message is automatically received by the consumer.. (2) Use the basic. GET command of amqp to obtain the Next message.
First, make sure you've turned off the openfire.Open terminal (in application--utilities--)Enter the following commandsudo rm-rf/library/preferencepanes/openfire.prefpanesudo rm-rf/usr/local/openfiresudo rm-rf/library/launchdaemons/org.jivesoftware.openfire.plistThe first one will let you enter the administrator password, although you enter the time, the terminal will not display, do not worry, the correct input and press ENTER, it is executed.After three orders, OpenFire disappeared completely.
