（一）. Web.Config是以XML文件规范存储,配置文件分为以下格式 1.配置节处理程序声明 特点：位于配置文件的顶部，包含在<configSections>标志中。 2.特定应用程序配置 特点: 位于<appSetting>中。可以定义应用程序的全局常量设置等信息. 3.配置节设置 特点: 位于<system.Web>节中，控制Asp.net运行时的行为. 4.配置节组 特点: 用<sectionGroup>标记，可以自定义分组，可以放到<configSections>内部或其它<sectionGroup>标记的内部. （二）. 配置节的每一节 1.<configuration>节 根元素，其它节都是在它的内部. 2.<appSetting>节 此节用于定义应用程序设置项。对一些不确定设置，还可以让用户根据自己实际情况自己设置 用法: I. <appSettings> <add key="Conntction" value="server=192.168.85.66;userid=sa;password=;database=Info;"/> <appSettings> 定义了一个连接字符串常量，并且在实际应用时可以修改连接字符串，不用修改程式代码. II. <appSettings> <add key="ErrPage" value="Error.aspx"/>

Understand and avoid infinite recursion R

由 痴心易碎 提交于 2020-02-20 08:46:04
问题 I can't find any advice on how to deal with infinite recursion in R. I would like to illustrate my problem in the most general way so that others can benefit from it. Feel free to edit it. I used to run a double for loop for (k in 1:n){ for (i in 1:m){ f[i,,k] <- an expression that depends on g[i-1,,k] g[i,,k] <- a mixture of g[i-1,,k] and f[i,,k]}} This was running fine but now I hoped to find the k that would best fit my criterion. So I decided to turn it into a function so that i could

Educational Codeforces Round 81 (Rated for Div. 2) B - Infinite Prefixes

由 孤者浪人 提交于 2020-02-02 09:39:51
Infinite Prefixes time limit per test 2 seconds memory limit per test 256 megabytes input standard input output standard output You are given string s of length nn consisting of 0-s and 1-s. You build an infinite string t as a concatenation of an infinite number of strings s, or t=ssss…t=ssss… For example, if s= 10010, then t= 100101001010010... Calculate the number of prefixes of tt with balance equal to xx. The balance of some string qq is equal to cnt0,q−cnt1,qcnt0,q−cnt1,q, where cnt0,qcnt0,q is the number of occurrences of 0 in qq, and cnt1,qcnt1,q is the number of occurrences of 1 in qq.

A delay between css animation repetitions

由 て烟熏妆下的殇ゞ 提交于 2020-01-25 03:05:27
问题 I am trying to create an animation where each letter is moved separately, which works fine but when I add infinite it does not have a delay between the loops so the letters are constantly moving one after another. I tried to add animation delay on the base animation but it just slows down the animation speed. @keyframes move { 0% { transform: translateY(0) } 100% { transform: translateY(4vh) } } .anim p { animation: move 0.7s ease-in-out forwards; animation-timing-function: linear; } .anim

Implementing the ruler function using `streamInterleave`

问题 I am doing the homework of CIS 194. The problem is to implement the ruler function by using streamInterleave . The code looks like data Stream a = Cons a (Stream a) streamRepeat :: a -> Stream a streamRepeat x = Cons x (streamRepeat x) streamMap :: (a -> b) -> Stream a -> Stream b streamMap f (Cons x xs) = Cons (f x) (streamMap f xs) streamInterleave :: Stream a -> Stream a -> Stream a streamInterleave (Cons x xs) ys = Cons x (streamInterleave ys xs) ruler :: Stream Integer ruler =

Deserialization of non-finite floating-point numbers fails even with appropriate facets

由 余生颓废 提交于 2020-01-23 14:08:23
问题 I need to use Boost.Serialization to serialize floating-point numbers. Since NaN and infinites cannot natively be read from an input stream, I am trying to use the facets in boost/math/special_functions. I have tested them on my platform using code similar to the examples we can find here: http://www.boost.org/doc/libs/1_50_0/libs/math/doc/sf_and_dist/html/math_toolkit/utils/fp_facets/intro.html However, the following code still fails to properly unserialize non-finite floating point values

C++多线程-读写锁

由 こ雲淡風輕ζ 提交于 2020-01-21 05:38:18
在编写多线程的时候，有一种情况是十分常见的。那就是，有些公共数据修改的机会比较少。相比较改写，它们读的机会反而高的多。通常而言，在读的过程中，往往伴随着查找的操作，中间耗时很长。给这种代码段加锁，会极大地降低我们程序的效率。那么有没有一种方法，可以专门处理这种多读少写的情况呢？ 有，那就是读写锁。 （1）首先，我们定义一下基本的数据结构。 typedef struct _RWLock { int count ; int state ; HANDLE hRead ; HANDLE hWrite ; } RWLock ; 同时，为了判断当前的锁是处于读状态，还是写状态，我们要定义一个枚举量， typedef enum { STATE_EMPTY = 0 , STATE_READ , STATE_WRITE } ; （2）初始化数据结构 RWLock * create_read_write_lock ( HANDLE hRead , HANDLE hWrite ) { RWLock * pRwLock = NULL ; assert ( NULL != hRead && NULL != hWrite ) ; pRwLock = ( RWLock * ) malloc ( sizeof ( RWLock ) ) ; pRwLock - > hRead = hRead ; pRwLock -
