Chapter 2 Smart Clients
The transformation of software from the host system to the C/S structure not only brings about reasonable allocation of system resources, but also brings about a new client experience, in particular, the extensive use of graphic interface systems (mainly Windows operating systems) provides a high-quality, Responsive user experience, and has good support for developers and platforms. However, it is very difficult to deploy and m
The most prominent feature of a smart switch is its ability to expand management capabilities to comprehensively improve network performance and responsiveness, allowing users to enjoy a free network environment. The increasing network scale or complexity makes management more difficult, greatly reducing network performance and user satisfaction. With basic management features, you can increase network performance and reliability, accelerate fault res
Thank you for your support for the smart UI. We apologize for the inconvenience caused by the version of the code downloaded over the past two days. Due to the environment problems, there are always more or less problems. Wait for the time to complete the download of vs2005-vs2010 versions.
Many friends are very interested in smart UI and many have raised many accurate questions. Thank you for your attentio

The control usually displays common properties or functions in the smart volume label, providing users with easier and faster settings, such as the intelligent gridview. To create a smart volume label for a control, you need to implement the actionlist of the control to be added to the project to be displayed in the smart volume label. This article takes the tdat
What is the background of the emergence of the smart cabling system? What is the current development stage? How much space is there? It is necessary to introduce these issues in the smart cabling system that has just attracted users' attention.
"The main reason why smart cabling systems began to emerge in the 1980s S was that network administrators were strugglin

To resolve the worries. The first edition of the C + + standard, revised in 1998, provided only a smart pointer: Std::auto_ptr (now obsolete), which is basically like a normal pointer: access

Vswitches play an obvious role in networking. As the exchange industry continues to develop, many new types of switches have emerged. Smart switches are one of them, when smart switches gradually move towards the edge of the network, they are always faced with various questions from users: whether smart switches are used to make minor use of the edge, whether the

In the article, we mentioned that this program has memory leakage (the manifestation is that the Destructor is not called), and three solutions are provided at that time:
Allocate the label object to the stack instead of heap.
Set tag space QT: wa_deleteonclose for label
Call Delete to delete the label object allocated to heap through new.

Java card is an intelligent card that can run Java program. For this new Java platform, sun's branch oft developed the Java card 2.0 API technical specifications. As a result, some authorized parties are implementing this API on the smart card. Java cards to be compiled and 2.0 concurrently should be in the procedural order. Developers must understand the internal meanings of Java cards from the physical structure, that is, the internal core class, an

Lead: The US IDG News Service published an analysis today that says smart Ben has a cheaper price and longer battery time than netbooks. With the Linux operating system to improve the user interface, access to more application support, based on the arm chip smart will gradually gain market acceptance, the use of Intel Atom Chip Netbook poses a significant challenge.

In short, when the memory is allocated to the stack, it does not need to be directly managed. When the memory is allocated to the stack, it needs to be manually recycled, or the automatic recovery mechanism is triggered when the memory allocation on the stack is full.The memory occupied by a C/C ++ compiled program is divided into the following parts:Stack: the stack is automatically al
Whether you admit it or not, as long as you surf the Internet, you may have to rely on WiFi. Yes, the WiFi has almost captured the whole world before you knew it.In terms of space, WiFi is like an invisible net, scattered in people's dense place. At home, on the road (transportation), in office buildings, restaurants, playgrounds, cafes, libraries and so on, WiFi is the most extensive non-signaling signal; equipment, ABI research found that by the end of 2014, A total of 9.98 billion WiFi device

The Chinese often say that "the fish and the bear's paw cannot have both sides", while the English often says that "XX is a double-edged sword ". In essence, this reflects world conflicts, and we must make trade-offs. However, I prefer the Chinese saying that it has a feeling of thinking carefully and thinking twice before a conflict occurs. When you realize that
The popularity of the current network makes smart life more and more widely used. Smart Home is also increasingly relying on the network and technology to move towards the future of SMART standards, the Network for the technology before the interconnection to build a bridge, the application of new technologies in life has made continuous progress in people's life

In the data center and telecom fields, technical staff will also create additional risks when they accidentally unplug some plug that should not be pulled. Assume that a VoIP switch or a key server is accidentally disconnected. As I have reported many times in recent news, what if a device with critical information gets disconnected? How does the network administrator know who is on the network? How are these operations recorded?
