i have 2 arraylists of varying sizes. example - array1.size() = 10 array2.size() = 5 want @ times these arrays have same size. thus, have class ensure this. obviously, isn't working me. please help! below class code - for (int = array2.size(); == array1.size(); i++) { array2.add(i, "test"); } the above loop doesn't add 'test' array2 matches size of array1. ideas guys? please help! since never equal array1.size(), loop never adds anything for (int = array2.size(); == array1.size(); i++) { array2.add(i, "test"); }

i'm fighting old c-style-interface. have function signature this: /// if return_value == null length returned void f( char * return_value, size_t * size_only_known_at_runtime); my question is, following code safe? std::size required; f( null, &required ); std::string s; s.resize(required); f( &s[0], &required ); is there better way data string? yes, it's safe, @ least explicitly c++11. [string.require], emphasis mine: the char-like objects in basic_string object shall stored contiguously . is, basic_string object s, identity &*(s.begin() + n) == &*s.begin() + n shall hold values of n such 0 <= n < s.size() . this resolution of dr 530 . before c++11, not explicit in standard, although done in practice anyway. in c++14, requirement got moved [basic.string]: a basic_string contiguous container (23.2.1). where [container.requirements.general]: a contiguous container container supports random access iter

is there way use _.omit on nested object properties? i want happen: schema = { firstname: { type: string }, secret: { type: string, optional: true, private: true } }; schema = _.nestedomit(schema, 'private'); console.log(schema); // should log // { // firstname: { // type: string // }, // secret: { // type: string, // optional: true // } // } _.nestedomit doesn't exist , _.omit doesn't affect nested properties, should clear i'm looking for. it doesn't have underscore, in experience makes things shorter , clearer. you create nestedomit mixin traverse object remove unwanted key. like _.mixin({ nestedomit: function(obj, iteratee, context) { // basic _.omit on current object var r = _.omit(obj, iteratee, context); //transform children objects _.each(r, function(val, key) { if (typeof(val) === "object") r[key] = _.nestedo

is there way move ccombstr object std::vector without copying underlying string? seems following code doesn't work. ccombstr str(l"somestr"); std::vector<ccombstr> vstr; vstr.push_back((ccombstr)str.detach()); your code doesn't work because detach gives bstr , not ccombstr . have used std::vector<bstr> vstr , long realise bstr points first character of string, there's length prefix before memory points (see, e.g. bstr (automation) ), you'd need careful managing it. alternatively, have used ccombstr str(l"somestr"); std::vector<ccombstr> vstr; vstr.push_back(str); which make copy of string. the msdn page on ccombstr not indicate has move-semantics, might have been added code without documentation being updated. don't think though, in case std::move solution in answer same second example: simple copy.

i want put string json.dumps() string = "{data}" print json.dumps(string) and get: "{data}" instead of: {data} how can string without quotes? method replace : json.dumps(string.replace('"', '') or strip : json.dumps(string.strip('"') does not work. you don't dump a string to a string. d = {"foo": "bar"} j = json.dumps(d) print(j) output: {"foo": "bar"} it makes no sense use string argument of json.dumps expecting dictionary or list/tuple argument. serialize obj json formatted str using conversion table.

we have set of subreports, can parametrized , shown on list of reports. problem is, these reports don't have pre-defined margin, there more space content , less. but couldn't make work tell subreport resize dynamically in width. if put in rectangle or grid, subreport has size has on sub-report itself, , not 1 tell him have via mainreport-designer. is there possibility make subreport resize in width dynamically? ssrs reports have specific width. includes sub-reports. answer question no, unfortunately.

papa parse appears causing chrome , opera crash (windows 7) if attempt parse "large" csv strings of 1 million rows 20 columns. same page loads in firefox. chrome , opera crash before calling parse if have large csv string defined , include <script> tag papaparse.js library. if don't include <script> tag papaparse.js there no problems creating large csv strings can't parse them. in actual use case, not generating large csv strings in javascript rather pulling them out of zip archive. doesn't appear make difference if use step or chunk functions. can run test case here; test case problem code; <!doctype html> <html> <script src="http://papaparse.com/resources/js/papaparse.js"></script> <body> <script> function my_createmockcsv(rows) { var my_csv="a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v\r\n"; (var i=1; i<rows; i++) { my_csv+= i+","+ i+","+ i+",&qu

i wrote script i'm using push updates pushbullet channels whenever new nexus factory image released. separate channel exists each of first 11 devices on page, , i'm using rather convoluted script watch updates. full setup here (specifically this script ), i'll briefly summarize script below. my question this: not correct way doing this, it's susceptible multiple points of failure. better method of doing this? prefer stick python, i'm open other languages if simpler/better. (this question prompted fact updated apache 2.4 config tonight , apparently triggered slight change in output of local files watched urlwatch , 11 channels got erroneous update pushed them.) basic script functionality (some nonessential parts not included): create dictionary of each device codename associated full model name get existing nexus factory images page using requests make bs4 object source code for each of 11 devices in dictionary (loop), following: open/create page

im having issue 'nav' area of email im coding. works fine in browsers , works responsively, ( http://imgur.com/3ivr3pu ) when opened in outlook. the code block below. any ideas how can make sit next left element? <layout label='nav'> <table border="0" cellpadding="0" cellspacing="0" align="center" width="580" class="devicewidth" style="mso-table-lspace:0;mso-table-rspace:0;"> <tr> <td> <table border="0" cellpadding="0" cellspacing="0" align="left" width="50%" class="devicewidth" style="mso-table-lspace:0;mso-table-rspace:0; border-collapse:collapse;"> <tr bgcolor="#9cacbc"><td class="borderbottom" width="50%" style="font-size: 13px; color: #ffffff !important; font-weight: normal; text-align: center; font-family: arial, helvetica, sans-s

i want know width(units) of particular letter or alphabet in particular font. for example if type in arial 10 pnts how space take in panel or text box or notepad. i tend not worry widths, instead leaving wpf format text nicely in whatever control i'm using. however, think can create formattedtext object using typeface , string "a" (amongst other things), , use minwidth property width in units of 1 / 96th of inch. this code started: formattedtext ft = new formattedtext( "a", cultureinfo.getcultureinfo("en-us"), flowdirection.lefttoright, new typeface("arial"), 32, brushes.black); double width = ft.minwidth; on system, sets width 21.343 . if put em-dash — in a is, (as expected) 32.0 , size specified em in fifth argument formattedtext constructor.

if django, can use allowed_hosts = [] in settings.py file. how rails? i think can try def local_allow_ip_ranges %w{ 127.0.0.1 12.123.1.123 192.168.1.0/255.255.255.0 } end now below method checks if given ip in above list def is_local(ip) require 'ipaddr' ip = ipaddr.new(ip) local_allow_ip_ranges.any? {|range| ipaddr.new(range).include?(ip) } end

i'm making final project in last year of college called "data flow diagram drawing tool" website based. having difficulties on how make warning when diagram in canvas wrong. example, terminator meets data flow meets process correct. when terminator meets data flow , meets storage wrong. how can make warning when mistake occurred? need kind of object definition each shape in canvas. how do that? need :( here's quick outline of how create , validate data-flow steps: create javascript objects hold information related each step in data-flow diagram. save step-objects in array easy processing iterate through steps array , validate each step. example code: // create javascript objects representing data-flow steps // , put steps objects in array easy processing var steps=[]; steps.push({type:'external',label:'customer'}); steps.push({type:'flow',label:'place order',isbidirectional:true}); steps.push({type:'process
