node.js - How do I decod node-hid data buffer from a&d scale -

-

i have a&d scale monitoring input using node-hid. reading input, can't figure out how decode binary data. appreciated.

this code using:

var hid = require('node-hid'); var devices = hid.devices(); var device = new hid.hid('usb_0dbc_0005_14400000');  device.on("data", function(data){     console.log(data); });

and gets spat out when scale @ zero.

<buffer 00 00 53 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00> <buffer 00 00 57 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00> <buffer 00 00 62 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00> <buffer 00 00 62 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00> <buffer 00 00 62 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00> <buffer 00 00 62 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00> <buffer 00 00 62 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00> <buffer 00 00 63 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00> <buffer 00 00 62 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00> <buffer 00 00 62 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00> <buffer 00 00 58 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00> <buffer 00 00 53 00 00 00 00 00> <buffer 00 00 00 00 00 00 00 00>

i ended writing buffer on whiteboard , thinking freely. found patterns in data , wrote code decoding , parsing scale data. code included below might need push in right direction.

"use strict";  var hid = require('node-hid'); var device = new hid.hid('usb_0dbc_0005_14400000'); var weight = [] var count = 0  module.exports.show_devices = function(){     console.log(devices); }  module.exports.start_logging = function(){     device.on("data", function(data){         var bad_array = [             '\u0000s\u0000\u0000',             '\u0000w\u0000\u0000',         ]         if (count < 20 && count % 2 == 0 && !contains(bad_array, data.tostring('utf16le'))){             weight.push(key[data.tostring('utf16le')])         }         if(count == 19){             display_weight()         }         if(count == 23){             count = -1             weight = []         }         count++     }); }  function display_weight(){     console.log(weight.join('')); }  function contains(a, obj){     for(var = 0; < a.length; i++){         if(a[i] === obj){             return true;         }     }     return false; }  var key = {     "\u0000y\u0000\u0000" : "1",     "\u0000z\u0000\u0000" : "2",     "\u0000[\u0000\u0000" : "3",     "\u0000\\\u0000\u0000" : "4",     "\u0000]\u0000\u0000" : "5",     "\u0000^\u0000\u0000" : "6",     "\u0000_\u0000\u0000" : "7",     "\u0000`\u0000\u0000" : "8",     "\u0000a\u0000\u0000" : "9",     "\u0000b\u0000\u0000" : "0",     "\u0000c\u0000\u0000" : "." }

PHP DOM loadHTML() method unusual warning -

-
i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
