问题 Hello I have a problem to retrieve a value from a method. I'm using sequelize in node.js. How can get placeTmp['id'] when I do this: server.js: var Sequelize = require('sequelize'); var sequelize = new Sequelize(config.database, config.username, config.password); var Place = sequelize.import(__dirname + '/model/Place'); console.log(Place.getActualId()); // An ID but I'll retrieve undefined :( Place.js: module.exports = function(sequelize, DataTypes) { var place = sequelize.define('Place', {

问题 I have got some problems using the following code, which is supposed to do gaussian fits using threads: from PIL import Image import numpy as np from scipy.optimize import curve_fit import threading class myThread (threading.Thread): def __init__(self, index): threading.Thread.__init__(self) self.index = index def run(self): for i in np.arange(n_Bild.shape[1]): curve_fit(self.gauss, x_x, Intensitaet[self.index, ...], p0=(Intensitaet[self.index, i], i, 1, 0)) def gauss(self, x, a, b, c, d):

问题 I need to create some variable defined in class source private to that class only. I am not able to move this variable to class header because of some other header file issue. I found this page http://en.wikipedia.org/wiki/Opaque_pointer and explains how it can achieve, Here is my class source struct testClass::testStruct { int a; int b; boost::asio::io_service io_service_2; client c_3(io_service_2); // this is another class, getting error here }; testClass::testClass(): test(new testStruct()

问题 I have a class file: we'll call it class.php . The functionality of that is to grab info from an ini file (yeah, I posted the question about security and was given the great suggestion to use either a config file or an ini file to hold the DB information). Essentially, my class is this: <?php class myClass { public function getAttached() { $file = "../../myFile.ini"; if (!$settings = parse_ini_file($file, TRUE)) throw new exception('Unable to open ' . $file . '.'); $hoost = $settings['mysqli'

问题 I really can not figure this one out. I have a VC called additionalMathViewController which displays questions to the user. If the user answers incorrectly the user is directed to another VC which is a subclass of additionalMathViewController called incorrectViewController. #import "ViewController.h" @interface additionalmathViewController : ViewController{ int currentQuestion; } currentQuestion is a counter variable which increases everything the user gets a question right and another

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 9 months ago . is it possible to set a c# variable with a different variable type value than what the variable one is setting? public class Test{ public DateTime TimeSinceEpoch { get {return TimeSinceEpoch; } set{ DateTime Epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc); TimeSinceEpoch = Epoch

问题 In eclipse 3.4 I'm trying to do some performance tests on a large product, one of the included libraries is the vecmath.jar (javax.vecmath package) from the Java3D project. Everything was working fine and then when trying to run it yesterday I get this exception/error not long after starting it up: java.lang.UnsupportedClassVersionError: javax/vecmath/Point2f (Unsupported major.minor version 49.0) Which I believe means that I'm trying to load a java 1.5 class file into a 1.4 jvm which is

问题 I searched a lot but couldn't find any solution. I am probably using the wrong keywords. I have a class which is basically an extended version of ListView control. I defined some custom attributes for my customized ListView, such as FileName, OrderType etc, and they work fine. I also want to pass an array to my class which includes ColumnNames to populate the data within class. In MyListView Class public class ColumnNames : Attribute { public string[] Values { get; set; } public ColumnNames

问题 I'm implementing enumeration using a base class that defines a variety of methods. The actual enumerations are subclasses of that, with no additional methods or attributes. (Each subclass is populated with its own values using the constructor defined in the base class). I use a registry (a class attribute that stores all the instances of that class). Ideally, I'd like to avoid defining it in each subclass. Unfortunately, if I define it in the base class, all the subclasses will end up sharing
