my journey being @ least on above basic level in front end still on , stumbled upon quite big problem recently. i can select dom element, like var element=document.getelementbyid("elementid") and add function it, this function testfunction() { alert(this.getattribute('data-self')); } element.customfunction=testfunction; but there chance way of doing using jquery? tried attr() , prop() , data() , without luck on matter. data() close 1 though, because allows me execute function using $('#my-element-id').data('customfunction')(); example, still doesn't solve problem, new property of selected buttons not accessible other way. to sum up: simplest way add generic function (like in example) collection of dom elements in way it's accessible other property? adding function directly dom element not considered practice variety of reasons. i'd suggest jquery plugin method pretty easy: jquery.fn.mymethod = function(

i'm working access data base, have users table. i have insert query : database.execute("insert users(userid,firstname,secondname,username,password,permission) values(" + obj.personid + ",'" + obj.firstname + "','" + obj.lastname + "','" + username + "','" + psw + "'," + permission + ")"); i checked parameters' values same table's ones... says there syntax error in insert query. parameters, parameters, parameters. first benefit code, forget single quotes. second, avoid dreaded sql injection vulnerability. third, code easier read. consider this: string insertquery = "insert table (field1, field2, field3) values (@par1, @par2, @par3)"; database.execute(insertquery, var1, var2, var3); where var1 , var2 , var3 variables containing values need insert. there's simpler (but worse, because it's still vulnerable s

i have read article: http://crackstation.net/hashing-security.htm and in section hash password, says better hash password in server, because if stole hash database can access user account without need of password. but if can stole hash database, can access whole database, correct? if correct, can access data, no of user information. why want part of information? an attacker tries steal database able access application. of course, if database contains sensitive information (like credit card numbers) not need access application if stole database. (the pci dss standard explains how store credit cards information) if found plain text password – able access application without problem. if database contains hashed value attacker need found plain text value corresponds hashed value. if use weak hash algorithms md5 or sha1 attacker can easier fine plain text value. for better protection recommended use strong hash algorithms sha128 or sha 256. in addition, recommend use d

arduino has c++ libraries use on pc platform. advantage 1 can test , debug arduino code on pc. easier debugging on pc. one library particularly keen on string library. https://www.arduino.cc/en/reference/string is possible somehow import arduino string library c++ ide visual studio given arduino library open-source? how can done? the string library free of platform-specific dependencies, add wstring.h , wstring.cpp source files. have little bit of porting (cleaning macros, suspect), there's no reason shouldn't build. many other libraries going considerably more difficult port on pc; touches peripherals of mcu not going port well.

i have work on 3 distinct applications instead of big one. question : "can jms used communicate between different servers (wildfly)" ? this way can add more servers second application if see take longs process. here simple exemple 15 servers. 5 first app take data , them. 5 second app calculate , last application format them , store them second db. if second app takes long, able add 3 servers on fly , let them connect first jms q , second jms q. maybe other suggestion how build ? thanks this pretty standard messaging. might depend on jms server, if use queues, each server should able consume individually , message process. the bigger issue going design of applications. need stateless message can picked server in order , processed without regard else happening. [of course, if there's shared back-end data provider shared among servers, provide context.] another issue going transactionality , recovery. if message picked server but, whatever r

i trying explore way use structure in opencl i first try struct (defined on host) typedef struct userstruct { cl_int x; cl_int y; cl_int z; cl_int w; } userstruct; and structure (defined on device) typedef struct userstruct { int x; int y; int z; int w; } userstruct; using defined structure, create 2 buffers (para_input , para_output) , init them different values. kernel function copies value para_input para_output. the example works fine. but, when add cl_int16 in struct, copying kernel not work. here modified structure: typedef struct userstruct { cl_int x; cl_int y; cl_int z; cl_int w; cl_int16 vn16; } userstruct; and structure (defined on device) typedef struct userstruct { int x; int y; int z; int w; int16 vn16; } userstruct; is there requirement align structure on both host , device? or popular way use structure in opencl? thanks. expanding on comment: it seems proble

currently in application, validating users using asp.net membership provider , asp.net default login page contains username , password. working fine 2 fields. per current requirement, need field "company" display dropdownlist in asp.net login page , validate 3 company, username , password using asp.net membership provider. possible or not, customize asp.net login page field using asp.net membership provider? please give me ideas how approach? membership provider's validateuser method accept 2 parameters - username , password. if override it, cannot pass 3 parameters. validateuser(string username, string password) basically, cannot use login control validate user. instead, want validate user yourself. here sample code - note: strip out codes in login control demo purpose. <asp:login id="loginuser" runat="server" onauthenticate="loginuser_authenticate"> <layouttemplate> <asp:textbox id="use

i created project excluding tests , want have tests web application. application not extensive, big enough such don't want re-start project. is simple creating folder 'test' in application directory? are there other things have adjust in other parts of program? thanks in advance. one option choose test framework , add app (probably adding gem , runing rake task depending of framework) another option edit config/application.rb , uncomment line: # require "rails/test_unit/railtie" also can create empty rails project , compare current app empty 1 copy/modify files different: config/application.rb , test/test_helper.rb

i have nsstring in store value 2534568 i want first number 2 , 5 , then 3 , on..... thanks advance since no correct answer has been provided far, must answer if didn't otherwise. don't want misleaded: nsuinteger len = string.length; unichar buf[len]; [string getcharacters:buf range:nsmakerange(0, len)]; here, buf contain characters can iterate through. alternatively, can use charateratindex: method too, although i'm not sure that's not slower plain array indexing. (thus should benchmarked if it's bottleneck, don't perform premature optimization, though.)

writing tests , ran across error. array's seem same me, apparently not. error i'm getting. idea on fix it? expected array [ 'a2t1511300361', 'a2t1511300362' ] array [ 'a2t1511300361', 'a2t1511300362' ] test.js var should = require('should'), io = require('socket.io-client'), path = require('path'), express = require(path.resolve('./config/lib/express')), mongoose = require('mongoose'), sinon = require('sinon') ... client.on('printerlist', function(list){ var temparray = []; temparray.push('a2t1511300361'); temparray.push('a2t1511300362'); console.log(temparray); list.should.equal(temparray); }); you cannot directly test array quality in manner doing. [1,2] , [1,2] may have same elements, different arrays. more formally: [ ] !== [ ] [ ] != [ ] you trying test deep equality. this, need check each array element. many

gmail (supposedly using recyclerview) in inbox displays items contain images , text. when given item selected/tapped triggers animation of image 'transitions' checkbox. i've seen examples of animations apply whole items (viewholders). however, have no idea how gmail app able animate images only. any appreciated. if there image in recycler view item , want start new activity animating image when recycler item clicked, add same transition name image view in recycler item image view in next activity. <imageview android:layout_width="100dp" android:layout_height="120dp" android:layout_margintop="10dp" android:id="@+id/image" android:scaletype="fitcenter" android:transitionname="bookimage"/> then through onclick listener start activity using activity options compat animate image. itemview.setonclicklistener(new onclicklistener() { @o
