多线程之临界区(Critical Section)
现在来具体的说下个人对临界区对象的看法和理解。   上一篇文章说过,线程的同步互斥对象分为两种:用户对象和内核对象。临界区属于用户对象而不是内核对象。   临界区(Critical Section):通过对线程的串行化来访问公共资源或一段代码,速度快、适合控制数据的访问。是保证某一时刻只有一个线程访问数据的简便方法。在任何时刻只允许一个线程对共有的资源进行访问。如果有多个线程试图同时访问临界区,那

Windows并发&异步编程(3)临界区Critical Section
临界区在并发编程中是一个非常重要的概念,有些时候也被叫做关键段。每个进程中访问临界资源的那段代码称为临界区(Critical Section)(临界资源是一次仅允许一个进程使用的共享资源)。每次只准许一个进程进入临界区,进入后不允许其他进程进入。不论是硬件临界资源,还是软件临界资源,多个进程必须互斥地对它进行访问。 临界区编程主要涉及有5个函数:初始化临界区Initial

临界区(Critical Section)的封装和使用示例
转自 [url]http://www.cnblogs.com/sixbeauty/p/3951406.html[/url] 这个做法其实是抄我老大的。服务器中,多线程经常需要使用临界区,为了简化代码的使用,把临界区封装为 CThreadLockHandle 类,通过封装,使用临界区资源每次只需要一行代码,而且只要确定对象的生存周期,就能完成对临界区资源的自动释放: 头文件:...

Windows 95 系统下的Critical Section(临界区域)的一个有趣的问题
[code=C/C++][/code]rn大家都知道Critical Section(临界区域)是用来同步线程见通讯的。我在multithreading applications in Win32书中(102页)看到这么一段话:rn在Windos NT中,如果一个线程要进入Critical Section(即调用了函数EnterCriticalSection)而在未离开的情况下就结束(即没有调用LeaveCriticalSection),该Critical Section会被永远锁住(指导进程结束)。然而在Windows 95中,如果发生同样的事情,其他等着要进入该Critical Section的线程,将获准进入。rn我很想知道,这到底是不是真的?所以我上传了简单的<em>关于</em>线程通讯的源码,在ThreadOne函数中把LeaveCriticalSection封掉),想证实下。我的系统是XP的,运行结果如下:rnXP: [img=C:\Documents and Settings\Kaoya\桌面\未命名.bmp][/img]rn望不同的系统者也试下,把结果贴上来看看。研究下。o(∩_∩)o...

学习笔记 -- Win32多线程程序设计(三) 同步机制 Critical section and Mutex
类似SendMessage() 为同步,PostMessage()为异步 线程中同步机制 Critical <em>section</em> Critical <em>section</em> 是一块线程共享资源,使用下面这些API, 来保证同一时间只有一个线程可以操作该<em>critical</em> <em>section</em>。 (即给资源加锁) void WINAPI InitializeCriticalSection(
mfc c++ 多线程同步 关键性代码段CRITICAL SECTION(二)
在mfc多线程,当多个线程都想访问同一个资源时,会导致线程冲突,数据出错,所以在多线程中,当一个线程对共享资源进行操作时,其余线程需要进行等待,当该线程完成操作时,才能占用该资源进行操作。Critical Section,临界区,就是在线程中执行这样的操作,对关键性代码段进行保护,避免数据混乱。例子:int a ,进入线程后进行a++,当多个线程同时运行,进行a++操作时,变量a的数据会变得无序混乱
windows下使用Critical Section和Mutex实现线程同步实例
利用<em>critical</em> <em>section</em> 和 Mutex两种不同的线程同步的方法实现生产者消费者<em>问题</em>。生产者线程要能够对一个计数器进行增的操作,并且将其输出在控制台上,消费者线程能够对这个计数器进行减的操作,并将其输出在控制台上。两种线程都共享一个计数器。 其中增、减计数器的数我设置为1~6随机。测试两种方法的对比,用网上整理出的一张表如下1、使用CriticalSection 方法时,有一个临界区c

Critical Route
DescriptionnnA tragedy happened recently in your city. A patient in <em>critical</em> condition, who needed urgent treatment, died when being transported to a big hospital in the capital of the state. What happened was that the ambulance was held up in the traffic, due to a rock that slid onto the road. People complained with the governor, who now desires to prevent similar events in the future. Unfortunately, rock slides are very common in this state, with many mountains and sierras. Thus, in order to minimize the number of tragedies due to rock slides and other unexpected occurrences, the governor decided to create alternative routes between each city of the state and the capital. For this, it is necessary to initially identify which road segments are currently <em>critical</em>, that is, if they are blocked it will be caused that there are no possible paths between some city and the capital. A road segment is a course of road that connects two different cities.nnYour task is to write a program for identifying these <em>critical</em> road segments.nnInputnnThe input is composed of several test cases. The first line of a test case contains two integers N and M that indicate respectively the number of the cities (2 ≤ N ≤ 100) and the number of road segments (1 ≤ M ≤ 10000). Each one of the N lines following contains the name of a city (letters only, at most 20 characters long). The first of these cities is the capital of the state. Each one of the M lines following describes a road segment, containing a pair of names of cities separated by a whitespace. Note that, as the mountains cause difficulty in construction of the roads, many road segments are one-way. A two-way segment is represented by two one-way ones. You should assume that there exists at least one path from each city to the capital. The end of the input is indicated by N = M = 0.nnOutputnnFor each test case your program should list the <em>critical</em> segments, one <em>critical</em> segment per line. Each <em>critical</em> segment should be represented by two names of cities separated by a whitespace. The <em>critical</em> segments should be listed in the same order they appear in the input; for each segment, the cities should be listed in the same order they appear in the input. If there exist no <em>critical</em> segments your program should print a line containing only the word “Nenhuma” (“None”). Print a blank line after each test cases.nnSample Inputnn6 10nPortoAlegrenGramadonCanelanNovoHamburgonPelotasnRioGrandenCanela GramadonCanela NovoHamburgonGramado NovoHamburgonNovoHamburgo PortoAlegrenPortoAlegre NovoHamburgonRioGrande PelotasnPelotas PortoAlegrenPortoAlegre PelotasnPelotas RioGrandenNovoHamburgo Canelan3 5nSacramentonSanFrancisconSantaClaranSanFrancisco SacramentonSacramento SantaClaranSantaClara SanFrancisconSanFrancisco SacramentonSacramento SanFranciscon3 4nRecifenOlindanPaulistanOlinda RecifenPaulista RecifenOlinda PaulistanPaulista Olindan0 0nSample OutputnnGramado NovoHamburgonNovoHamburgo PortoAlegrenRioGrande PelotasnPelotas PortoAlegrennSantaClara SanFrancisconnNenhuma

It describes original research models and applied solutions for protecting major emerging threats in Critical Infrastructures and their underlying networks. It presents a number of emerging endeavors, from newly adopted technical expertise in industrial security to efficient modeling and implementation of attacks and relevant security measures in industrial control systems; including advancements in hardware and services security, interdependency networks, risk analysis, and control systems security along with their underlying protocols. Novel attacks against Critical Infrastructures (CI) demand novel security solutions. Simply adding more of what is done already (e.g. more thorough risk assessments, more expensive Intrusion Prevention/Detection Systems, more efficient firewalls, etc.) is simply not enough against threats and attacks that seem to have evolved beyond modern analyses and protection methods. The knowledge presented here will help Critical Infrastructure authorities, security officers, Industrial Control Systems (ICS) personnel and relevant researchers to (i) get acquainted with advancements in the field, (ii) integrate security research into their industrial or research work, (iii) evolve current practices in modeling and analyzing Critical Infrastructures, and (iv) moderate potential crises and emergencies influencing or emerging from Critical Infrastructures.

CRITICAL CHARACTERISTICS OF MALE
Difficulties that have limited research on serial murder (i.e., definition, data, and conceptual framework) are addressed by the current study. Hickey's Trauma-Control Model is utilized as a conceptual framework that is particularly helpful when sexual activity is involved. This study provides a rich description of male perpetrator characteristics (criminal history, age, and ethnicity), killing career characteristics (number of v&tims, length of career, solo or team killer, venue, weapons, and murder rate), and victim characteristics (relationship to killer and victim sex). Relationships among these characteristics are also examined.

询问关于web.config的问题,关于使用section和appsettings的区别?
使用了<em>section</em>来定义一个新的分组来访问自己定义的数据库联接,rn比使用appsttings来固定数据库联接更加适合网站的变更,移植!rn因此我参考一个调用<em>section</em>来编写一个分组来定义数据库联接使用,但是出了<em>问题</em>,但是我不知道出<em>问题</em>在哪里?还有就是调用<em>section</em>需要注意哪些事项?请高手指教,我的webconfig如下rnrnrnrn rn rn rn rn rn rnrn rn rn rn rn rnrn rn rn rnrn rn rn rnrn rn rnrn rn rn rn rn rn rn rn rn rnrnrn rn rn rnrnrn调用的时候我使用了rnusing System.Data.SqlClient;rnusing System.Collections.Specialized;rnstring strConn=(String) ((NameValueCollection)Context.GetConfig("system.web/database"))["strConn"];rnrn但是在调试的时候报错,说无法找到匹配的database?rn还有就是我这样调用<em>section</em>是否正确?这样和调用appsetting有什么区别呢?rn为何已经新建一个分组database了,为何在webconfig里面还有一个appsetting?rn我这次测试是在看到rnhttp://blog.csdn.net/scorpion007/archive/2005/02/22/297210.aspxrn这里的文章学习遇到的,所以提出,希望各位高手指教!rn不胜感激rn一个初学.net者

Section V2
Sectionj是在Windows XP系统和MapGis6.7(B20051118)基础上,以Microsoft VC++ 6.0为编程语言,MapGis 6.7 SDK为开发平台进行开发的地质图件制作软件。系统基于MapGis输入编辑子系统强大的图形编辑能力,添加专业的地质图件制作工具,大大提高了地质图件的制作效率,能够很完美的转换CAD数据格式为MapGis格式。地质数据采集系统采用Microsoft Access的MDB格式,自动计算绘制符合行业标准的MapGis格式地质图件。
section使用方法
几年之前,看到<em>关于</em><em>section</em>的使用百思不得其解,最近又重新探究了。 形如: struct A { int a; int b; }; A attribute((used, <em>section</em>(“test”))) a; A attribute((used, <em>section</em>(“test”))) b; extern “C” attribute((visibility(“h...

Conic Section
The conic <em>section</em>s are the nondegenerate curves generated by the inter<em>section</em>s of a plane with one or two nappes of a cone. For a plane perpendicular to the axis of the cone, a circle is produced. For a plane that is not perpendicular to the axis and that intersects only a single nappe, the curve produced is either an ellipse or a parabola. The curve produced by a plane intersecting both nappes is a hyperbola.nnnconic <em>section</em> equationncircle x2+y2=a2nellipse x2/a2+y2/b2=1nparabola y2=4axnhyperbola x2/a2-y2/b2=1nInputnnThere are multiple test cases.
