问题 I am trying to restrict the user to enter max 50 words in UITextView. I tried solution by PengOne from this question1 . This works for me except user can enter unlimited chars in the last word. So I thought of using regular expression. I am using the regular expression given by VonC in this question2. But this does not allow me enter special symbols like , " @ in the text view. In my app , user can enter anything in the UITextView or just copy-paste from web page , notes , email etc. Can

Word Is In Dictionary or Not

由 怎甘沉沦 提交于 2019-12-07 18:14:08
问题 I am trying to see if a word is in the dictionary or not. Is there any way to do that? 回答1: Get a list of (assumingly) English words and put it in a database (probably Sqlite for portability). You can get lists of words here: http://wordlist.sourceforge.net/ Or here (found at https://stackoverflow.com/questions/824422): http://www.curlewcommunications.co.uk/wordlist.html Use a library corresponding to the database of your choice to query the table for a word. Here's a Sqlite engine written in

最近做一个系统的维护改善工作，从来没接触过的业务，代码中没有一句注释。各种bug堆积转狂。 一条改到导出word的功能的时候，系统使用了jacob操作但是系统一直报错， Exception in thread "main" java.lang.UnsatisfiedLinkError: no jacob in java.libr ary.path 查了下资料 ，基本都是说没正确的放入library中，并提供了3处以上的位置，实际测试后只要放在 \Java\jdk1.6.0_32\jre\bin下就可以了。 重新配置了myeclipse的jre 选择了tomcat的jdk 重新启动后发现系统仍然报着个错误，考虑我用的是win7 64位 安装的是64位的jdk，重新下载了一个32位的安装了一下，仍然用jacob-1.17-M2-x86.dll 。依据报如上的错误。 于是我将dll重新命名成jacob.dll运行在系统中。 系统报错 j ava.lang.UnsatisfiedLinkError: com.jacob.com.Dispatch.createInstance(Ljava/lang/String;)V 我查了一下大体上是说jar和dll的版本存在冲突，我调试了用最新的版本仍然存在这个问题。 于是怀疑是自己的项目有问题，但是也没有找到什么疑问点。就重新写了一个新项目

Need a program to reverse the words in a string

由 时间秒杀一切 提交于 2019-12-06 13:01:01
问题 I asked this question in a few interviews. I want to know from the Stackoverflow readers as to what should be the answer to this question. Such a seemingly simple question, but has been interpreted quite a few different ways. 回答1: if your definition of a "word" is a series of non-whitespace characters surrounded by a whitespace character, then in 5 second pseudocode you do: var words = split(inputString, " ") var reverse = new array var count = words.count -1 var i = 0 while count != 0

Please see below a question regarding word sizes in various instruction set architectures, and how that ties to assembly languages. Thank you for any and all help. First a few facts (please correct me if any of these are wrong). The word size of a processor architecture indicates (EDIT: Some of these were wrong, please see Seva's post below) : The largest size of each register The largest size of each memory address (amount of memory that can be addressed) The largest integer the CPU can process in a single instruction Largest piece of data that can be transferred to and from the working

问题 how i can change 'comment' word to 'review' from total number of comment [ 6 comment ] -> [ 6 review ] 回答1: You do this on the Disqus website, in "Settings" > "Appearance" ( http://your-site-slug.disqus.com/admin/settings/appearance/ ). Almost at the bottom of that page, you have the "Comment count link" setting, where you can change the text for zero, one or more comments. 回答2: This is updated GUI you can find it "Settings" > "General" and if you need to remove 'comment' word you can't so
