node.js - NodeJs looping through object variables behaving strange -

-

I am running mysql from within a loop, for some reason my variable is being overwritten.

Under my code: 

  setInterval (function () {for s_bots in var} {if (_bots.hasOwnProperty (s)) {var obj = _bots [ S]; for (var in Obj) {console.log ('-----' _bots [s] [Sahara]. Channel + '-----'); channel = _bots [s] [Sahara] Channel, CC = S; dd = prop; var sql = 'SELECT * FROM `usrs' Where CID =' + connections. Escape (_bots [s] [prop] channel) + 'border1'; connection. Query (SQL, function, result) {if (results.length! = 0) {console.log ('NAME --- & gt; '+ cc;) console.log (' MSG_TO --- & gt; '+ dd); console.log (' id --- & gt; 'channel);} Other {// ....}}}}}}}}, 15000)   
 The problem is that  NAME - & gt; MSG_TO - & gt; Variable (CC, DD, and Channel)  Always keep the last value from the object. For some reason they are overlapping .. Strangely I do not have permission to use in my code for  s  and  prop  inside mysql selection function.  
 I have a           > 
 
 The expected behavior is that each one of your for..in loop defines a closing, and all closures have the same function scope in their scope chains Refer to. Whereas  cc ,  dd , and  channels  are all variables in this area, of course you get the same output.  
 If you want different outputs, to force these variables before their values ​​change. Try:  
  connection.query (SQL, function (CC, DD, channel, fault, result) {if (results.length! = 0) {console.log ('NAME - - & gt; '+ cc;); console.log (' MSG_TO --- & gt; '+ dd); console.log (' id --- & gt; 'channel);} Other {//. ..}} .bund (tap, cc, dd, channel)); // Force values ​​here

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

I am using a Google line chart on my page, which refreshes every 5 seconds but weird thing It is that every refresh chart causes the line to be removed, although the size of the chart remains the same. My script - google.load ('visualization', '1', {package: ['corechart']}); Google.setOnLoadCallback (drawLine); // call clickChart when the google.load () function meets the drawLine () {var gaugeData = new google.visualization.DataTable (); GaugeData.addColumn ('string', 'time'); // X-axis gazeta.dk column ('number', 'memory'); // Y-axis gazedata.edc column ('number', 'cpu'); // Y-axis square gauge option = {title: 'system description'}; // tile of var gauge chart; Var tempArray; // store json object value from server var tempArray2; // Server gauge = Modify the json object value = new google.visualization.LineChart (document.getElementById ('line_chart_div')); SetInterval (function () {$ aja...

So, I ended up making a Sudoku Solver, but I want to improve it. To do this, I need to reach betterJTextField to documentListener . I am using a documentListener to read from my betterJTextFields in real-time, I have the problem that insertUpdate (DocumentEvent e) . I need to reach Better Zest Field that happened to DocumentEvent . For example, if invalid input, would be better zestfield turn red etc. I have all my better zestfield in the matrix if you should know. Each area handles a number in the Sudoku. @ Override public zero inserted (DocumentEvent e) {// Code removed which checks that the input in the fine zest field is OK. } ( JFormattedTextfield extended JTextField ) public class betterJeststeffiledJFormattedTextField {private int row; Private int column; Public BetterJustStस्टfield (format format, infinite row, EIT column) {super (format); This.row = Line; This.column = Column; // To-O Auto-Generated Constructor Stub} Public Ent Miller () {ret...
