store

问题 I want to use a combobox which receives the preselected value from a data binding and also the possible options from a data binding of the same store. The panel items configuration looks like this: { xtype: 'combobox', name: 'language_default', fieldLabel: 'Default Language', multiSelect: false, displayField: 'title', valueField: 'language_id', queryMode: 'local', bind: { value: '{database.language_default}', store: '{database.languages}' } } If I use this configuration, the store of the

问题 y = find(sA); l = y + sA; for i=1:10 for j=1 l = l + sA; end y = y + length(y); end I would like to know how to store the value that is generated for l , for each iteration, in an array. When I try do something like l(l) = l + sA; I obtain 'weird' results. NOTE: PLEASE READ MY COMMENTS POSTED BELOW. THANKS! 回答1: For a complex loop, usually I do something like this: results = zeros(expectedLength,1); ixNextResult = 1; for ixForLoop1 = 1:10 for ixForLoop2 = 20:30 .. results(ixNextResult) =

问题 I'm creating a small program that saves a int value into a text file, saves it, and loads it when you start the program again. Now, I need 3 more booleans to be stored in the text file, I am writing things in the file with public Formatter x; x.format("%s", "" + m.getPoints() + "\n"); Whenever I want to go to a new line in my text file, with \n, it wont go to a new line, it will just write it directly behind the int value. I tried doing both x.format("%s", "" + m.getPoints() + "\n"); x.format

问题 I'm doing a fairly complex emberjs application, and tying it to a backend of APIs. The API calls are not usually tied to any particular model, but may return objects of various types in different sections of the response, e.g. a call to Events API would return events, but also return media assets and individuals involved in those events. I've just started with the project, and I'd like to get some expert guidance on how best to separate concerns to have a clean maintainable code base. The way

问题 Following with this question R: from a vector, list all subsets of elements so their sum just passes a value I´m trying to find a way to store the values given by the print command in a vector or matrix but I can´t find any way to do it. The code is: v<-c(1,2,3) threshold <- 3 # My threshold value recursive.subset <-function(x, index, current, threshold, result){ for (i in index:length(x)){ if (current + x[i] >= threshold){ print(sum(c(result,x[i]))) } else { recursive.subset(x, i + 1,

问题 I'm trying to create a database to manage autobus data CREATE TABLE Company( Company_Name VARCHAR(12), Tel INT, PRIMARY KEY(Company_Name) ); CREATE TABLE Line( ID_Line VARCHAR(3), NCompany_Name VARCHAR(12), Desc TEXT, PRIMARY KEY(ID_Line, Company_Name), FOREIGN KEY (Company_Name) REFERENCES Company(Company_Name) ); CREATE TABLE Stop( ID_Stop VARCHAR(3), geoLat FLOAT(10,6), geoLong FLOAT(10,6), PRIMARY KEY(ID_Stop) ); CREATE TABLE Make( ID_Stop VARCHAR(3), ID_Line VARCHAR(3), Hour TIME,

问题 I have a program which manage resources (agents). In the program there is a feature to select a date from a calendar (e.g.: 08/11/2013 5 a.m.) and get back the number of available resources at selected time. How can I store the status of the resources for every hour of all day in the year effectively in a relational database? Resource status just a string: "accessible" or "busy". Have you any idea or strategy for this? Thanks for help! 回答1: The best way to store effective date(/time) ranges

问题 I am getting frustrated while working with store and model of extjs 4. I am getting Store defined with no model. You may have mistyped the model name. error even though I have specified model name inside store. Here is my code : Ext.define('iWork.store.CandidateDistribution', { extend: 'Ext.data.TreeStore', autoLoad: true, requires: 'iWork.model.Location', model: 'iWork.model.Location', proxy: { type: 'ajax', url: 'data/CandidateDistribution/CandidateCount.json', reader: { type:
