Tip: because the project is a little too big for me personally, it may be unclear in some aspects or the logic is not strong enough. If you have any questions, please @ me in time.
To send a custom message package, you must design the message structure between the client and the server.Package com. imomo_msg;/*** Symbol = '+': this fi

When you open the Sina Weibo app on your mobile phone or the zhihu app, do you want to find out where the images and data displayed on your mobile phone come from? What method is used for implementation? Okay, so next we will introduce how it is implemented and what the process is like.
When we browse Weibo websites that follow or are close to our friends, the images and data are no
CS-> BS-> richclient-> smartclient
In traditional enterprise application development, CS is generally used. This development method features high data transmission efficiency and user interface friendliness, A large amount of user personalized information can be stored on the client. However, this method also has its disadvantages, that is, the application scope is too narrow and is generally limited to the enterprise LAN, in addition, a complete client must be installed on each terminal. Pro
tools are used in the same way on these platforms. Therefore, the development and deployment of QT applications are irrelevant to the platform. In a desktop system, QT is usually an application that complies with the X protocol and requires the support of the X server.
QT/E is the QT version used for Embedded Linux systems. The dependencies of X lib are removed from QT/E and directly work on frame buffer. Therefore, the processing efficiency of applications is relatively high. It can run as lon

First to tell me about the entire socket communication process understanding, after all, beginners, say wrong forgive, know wrong will correct ~
First, create a new serversocket on the service side, initialize it (generally contains ADDRESSFAMILY:IP address type, sockettype:socket transmit data way, ProtoType: Transmission protocol);
Then we set up the server-side ip:port to bind, and then start listening and set up the number of client listeners simultaneously.
At this point, the server is w
Methods that clients can also connect to databases without installing Oracle
This paper takes oracle8i as an example:
First install an Oracle client,
Keep the Bin,network,ocommon three directories under the Oracle directory, and delete all the rest,
Export hkey_local_machine/software/oracle in the registry.
When you install a new machine, copy the Oracle directory and registry files into the registry, register with the Oracle/bin path, and restart.

Recently, the company has a lot of people reflect the Outlook 2010 clients sometimes can not download mail, OWA is normal to see new mail, after testing, found that there are two reasons, here to give you a reference:

Analysis: By looking at Microsoft's official website, you cannot have more than 5000 messages per folder in your Outlook mailbox, or you may not receive messages correctly
