问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . I'm trying to find a JS library, for coverting .ini file to .json file I need that all oparations will be in client-side(!!!), so https://www.npmjs.org/package/clonkrefiniparser is not helping me.

问题 I need to be able to read a char and get it's Key relevant to it's language and keyboard layout. I know how to see the cultural settings and languages. But how can i take a letter like 'S' in english and know what key it is on the keyboard? Or for a harder problem, how can i take the letter 'ש' and know what key it is on the keyboard? 回答1: This one might be more easily explained with an example program than anything else: namespace KeyFinder { class Program { [DllImport("user32.dll", CharSet

问题 What is the best way to convert various audio formats to PCM? For example: mp3, evrc, ogg vox. Is there a library out there that will allow me to implement this relatively easily? EDIT: I guess my initial question wasn't really what I needed. Most of the libs I have found are file converters. What I need is a block converter, where I pass in a 1Kb block of vox data and it returns its converted PCM block. Of course I’ll have to tell the converter what type of data it is and various pieces of

问题 trying to make a converter of binary to denary in java, but I'm not sure whats going wrong, I have a feeling its in my loop, any help would be much appreciated! I am following pseudo code if you would like to see it! System.out.println("Enter a binary number"); Scanner sc = new Scanner(System.in); String binaryString = sc.next(); int binaryLength = binaryString.length(); int multiplier = 1; int denaryValue = 0; for(int n = binaryLength; n >= 1; n--){ int digit = n; denaryValue = denaryValue +

问题 So I found a list of Converters on MSDN today, now I want to use some of them. However after searching a bit I can t seem to find ANYTHING about them. I mainly want to use the IntToBoolConverter. However I got no clue how to use the convert since there is no info provided how to do it(or on google). I know it is easy to make this converter myself, but I am a programmer and my moto is be lazy when you can and making methods(converters) that already exists is redundant work. Hope someone can

问题 I've looked at the other questions this and this, etc, the problem is that my convert gets called but the values of selectOneMenu doesn't change . My entity class is generated, and has equals as well as hashCode and I would like not to change anything in it - if it gets regenerated then all changes will be lost (The work around is to change toString of the entity class). The XHTML code snipped: <p:selectOneMenu id="defid" value="#{abcController.selected.defid}" converter="defConverter"> The

问题 I've got a script that runs when a torrent download is finished to see if there are FLAC audio files and if yes convert them to MP3. Until today I've used: for file in "$torrentpath"/"$torrentname"/*.flac do ffmpeg -i "$file" -qscale:a 0 "${file[@]/%flac/mp3}" done But I realised that when a torrent comes containing sub-directories the script is useless. I've tried messing around for the past few days with "find" and "if" and other ways but I can't really see the answer. I know it's there.

问题 Basic Joda Time converter (the code is absolutely superfluous for the context of this thread) : @Named @ApplicationScoped @FacesConverter(forClass = DateTime.class) public class DateTimeConverter implements Converter { @Override public Object getAsObject(FacesContext context, UIComponent component, String value) { if (value == null || value.isEmpty()) { return null; } try { return DateTimeFormat.forPattern("dd-MMM-yyyy hh:mm:ss aa Z").parseDateTime(value).withZone(DateTimeZone.UTC); } catch
