i have basic knowledge of ios programming, though, understand concepts , limits (and i'am experienced programmer on other platforms). i asked prepare project, require ios app download basic office files (whenever available) , keep them in local ipad storage, accessible offline. sake of simplicity let's say, published on kind of web servers. , should work on 3g. now, understand, first way keep data (files) date synchronize them whenever user opens app , has access network (internet). it becomes more complicated when need in addition try keep them synced while app not running / ipad/iphone lays on table. is possible use f.e. "background fetch" (or other mechanism) download files in background? know 30 second window (this should enough, or - if must enough, can adapt synchronized files sizes make possible). don't need have strict intervals, nice, though. i understand, when files stored locally, it's not rocket science open them in installed apps (li

i not understand why cmd command wmic cpu processorid works on 2 of 3 computers on third returning "invalid namespace" what wrong? you might want try running "wmic cpu list /format:list". guess different version of wmic , name of variable different. command should give list of able wmic cpu call.

i'm project on financial data visualization. nothing advanced really, user input manipulated , visualized output charts , numbers. thing though, though plan have .net desktop application begin idea later transform web based application. , since i've got no experience whatsoever question simply: can 1 write desktop application in c# .net , later "upload" or "convert" web based interface without work? i've heard of asp.net seems pretty used framework web applications, cannot find converting desktop application asp.net application. thanks in advance! if divide application parts should - e.g. business logic, data access layer etc (into different dlls preferably), need create new ui, isn't bad creating app scratch... there confusion in definitions. (and seems of guys posted answers here) have misunderstood technology. you can't compare asp.net c#, because 1 web framework, other programming language. asp.net can , use c# (or vb

i create tex table using xtable() . here's minimal example worked when used same r version on win 7. \documentclass[a4paper,12pt,twoside]{article} \begin{document} <<load-packages,include=true,echo=true>>= library(xtable) @ <<testing-xtable,echo=true,cache=false,include=true>>= tab <- matrix(1:50,nrow=10) rownames(tab) <- letters[1:10] print( xtable( x=tab, caption="a table", label="tab", align=rep("c",times=6), digits=3, display=rep("f",times=6) ), sanitize.colnames.function=identity, include.rownames=false, table.placement="h" ) @ \end{document} instead of nice table verbatim code output of xlatex() in pdf document. here's output of knitr: > grdevices::pdf.options(usedingbats = false); require(knitr); opts_knit$set(concordance = true); knit('xtable.rnw', encoding='utf-8') loading required package: knitr processing fil

i want create query show artists thay in reggae , rock music try not work.. [{ "id": null, "name": "rock music", "or:name": "reggae", "type": "/music/genre", "/music/genre/artists": [] }] since you're after artists, i'd recommend turning query inside out , asking artists, not genres. return artists names, ids, , genres artists include genre of rock music or reggae: [{ "id": null, "name": null, "type": "/music/artist", "genre": [{ "name|=": [ "rock music", "reggae" ] }], "g:genre": [] }] it's more robust use ids genres rather names in case decides genre should called "rock" instead of "rock music."

im hoping can point me in right direction. i have php page, includes html markup , js/jquery routines build array of 'user choices' based on 'user input' (checkboxes..etc). my question is, how can pass off (multidimensional) array php, in same page? (ultimately want save data/array php session) while looking around, read using (external) .php script do,, not im after, i'm hoping same page i'm in... without refresh. will $.post() me? without page refresh (if suppress event or whatever)... , -not- using external .php script? i understand php runs/executes first... else.. i'm not trying php data being sent js/ajax.. outside of save session array.. ajax seems needed? to summarize: 1.) php , js in/on same page (file) 2.) no page refresh 3.) no external php script 'anything'. 4.) trying (multidimensional) array php session in same page. 5.) trying 'update' php session array each time user 'clicks' on checkbox.

i'm trying write script make map larger on google flights . i've got jquery working in firefox scratchpad. script trying accomplish: $('div').filter(function(){ return $(this).css('width') == '648px' }).css({"width":"900px","height":"550px"}); but when paste greasemonkey script, doesn't work. if add console.logs debug, can verify script running , filter working correctly, it's not modifying css. ideas? sometime need make sure script executed after page loaded $(function(){ // code here }); you can try settimeout , put 2sec (2000) var myfunc = function(){ // code here }; settimeout(myfunc, 2000);

recently i've been getting programming in c++ , have come across interesting while programming else. in code below defined class pointer member gets deleted in class' destructor. i have defined function takes test_object object argument calls 1 of get_val() method nothing more report value held in memory address pointer pointing to. now when call function twice correctly prints value in held internal pointer correctly once, core dumps after second. correct me if i'm wrong, believe reason happens because after first time function called object's destructor called because object has gone out of scope , destroyed. the way think of preventing passing object reference. there other way prevent happening? seems bit dangerous pass object reference since object can modified in function call lead headaches later on. i've tried making argument const, error stating ‘const test_object’ ‘this’ argument of ‘void test_object::get_val()’ discards qualifiers argument.

this question has answer here: efficiency of c#'s typeof operator (or whatever representation in msil) 3 answers i have code executes typeof many times inside loops. i'm wondering if should call typeof outside loops , use variable? my code this. for(int i=0; < 1000; i++) { type t = foo(i); if(t == typeof(string)) { //.... } } is following code faster, slower or no difference? type s = typeof(string) for(int i=0; < 1000; i++) { type t = foo(i); if(t == s) { //.... } } instead of running few c# tests see runs faster. i'm looking answer can explain happens when typeof used. does produce compile time constant? no (as in extremely negligible), typeof() done @ compile-time--the work type comparison. should asking why you're checking types when using polymorphism.

can explain me connection pooling in ado.net , throttling in wcf same. they seem similar. sql connection pooling reusing. connecting database server typically consists of several time-consuming steps. physical channel such socket or named pipe must established, initial handshake server must occur, connection string information must parsed, connection must authenticated server, checks must run enlisting in current transaction, , on. in practice, applications use 1 or few different configurations connections. means during application execution, many identical connections repeatedly opened , closed. to minimize cost of opening connections, ado.net uses optimization technique called connection pooling. connection pooling reduces number of times new connections must opened. pooler maintains ownership of physical connection. manages connections keeping alive set of active connections each given connection configuration. whenever user

double rainpermonth(const int years) { int monthyear[months][years]; // ... } visual studio shows squiggly line underneath array declaration, saying years must constant when i'm creating array. ide issue because variable has yet initialized, or writing incorrectly? months declared globally. an array size must constant expression - is, value known @ compile time. (some compilers offer c-style variable-length arrays non-standard extension, don't think visual c++ does. if does, it's better not rely on such extensions.) a function argument isn't known @ compile time, can't used array size. best option here probably std::vector<std::array<int, months>> monthyear(years);

i read csv file in javascript written windows store app. if use readtextasync error when using german umlauts. no mapping unicode character exists in target multi-byte code page. i found solution in c# here readtext file in ansii encoding have no idea how solve in javascript? is there someting encoding class in javascript? if convert file utf8 works fine, customer use file saved excel. excel not use utf8 default. the simplest convert file utf-8 that's accessed winjs. there isn't equivalent code in winjs library found c# (for reason, it's not exposed). there simple encodings available utf-8/16(l/h). so, if don't want convert file , you're using javascript, i'd create simple windows runtime component ( walkthrough ) contains behavior want. it's quite simple if follow walkthrough. basically, write code in c#, , when done per rules, becomes available in winjs component. code you'd need write relatively straightforward well: public s

i'd have text inside gridster grid , make text-align: center , vertical-align: middle . <li><span>text</span></li> i tried this: .gridster .gs_w > span { text-align: center; vertical-align: middle; } only text-align works. can't use line-height because every grid's height different based on user choose. i assume because not have height , width directly, that's why margin: auto 0px; doesn't work either. got height , width via data attributes. does know gridster's css behavior? how vertically center elements (image or text) inside grid? this how add elements via ajax $.getjson( "data/tiles.json", function( json ) { for(i=0; i<json.length; i++) { gridster.add_widget( '<li class="gs_w" id="'+count+'" style="background-color: '+json[i].rgb+'"><span>teszt</span></li>', json[i].size_x

i've studied similar questions on haven't found solution problem... i've set express route serve images can't return image it's stored. notice i've included statement allow requests origin. happens when make request http://localhost:8080/images/x10.png response empty image element src="http://localhost:8080/images/x10.png instead of http://ubuntubox.dev/images/x10.png , image located , path i'm passing request method. missing? thanks. app.get('/images/*', function(req, res, path){ var imagepath = req.url, url = 'http://ubuntubox.dev' + imagepath; request(url, function(error, response, img) { if(!error && response.statuscode === 200) { res.header('access-control-allow-origin', '*'); res.writehead(200, {'content-type': 'image/png' }); res.end(img, 'binary'); } else if(response.statuscode === 404) { res.status(404); res.type('txt

i'm experimenting pnrp, using netsh execute basic commands register peers on machine. able add multiple peers on machine opening multiple instances of command prompt, , entering following commands netsh p2p pnrp peer add registration 0.mike after switch cloud context , enter show names , see bunch of info, , names of 2 peers registered through cmd . however, when ask developer (who has machine on same ipv4 subnet) run same commands not appear. expect third peer show on cloud, since we're using same name 0.mike what not understand going on here, , should doing behavior i'd expect? show names designed show names registered on local machines, not names computer aware of. due way name storage works (a 1 way hash algorithm) nodes of network aren't aware of names storing, hashed values. the command want run resolve 0.mike perform lookup name , return ip addresses. can restrict cloud if need to.

i learned terminary expression, want little different. i have following: int mode = getmyintvalue(); i comparison following: if(mode == 1 || mode == 2 || mode == 3) //do i know if there short way of doing this, tried didn't work: if(mode == 1 || 2 || 3) //do there short|quick way of doing it? quick "ifs" because makes code more clear, example, more clear this: system.out.println(mode == 1 ? text1 : text2): than this: if(mode == 1) system.out.println(text1): else system.out.println(text1): thanks in advance! well, if don't mind boxing hit, use set prepared earlier: // use more appropriate name if necessary private static final set<integer> valid_modes = new hashset<>(arrays.aslist(1, 2, 3)); ... if (valid_modes.contains(mode)) { } you use int[] , custom "does array contain value" method if wanted... o(n) or o(log n) binary search, suspect we're talking small sets anyway.

i'm adding image word document using openxml. i able tell size of image being added, , can resize if want to. want resize if it's wider current column. (in case, there 1 column perhaps change.) is there way know how wide current column and, therefore, able ensure image fits within column? is, large images extending off page. i've updated answer, because answer case when table columns involved, word column in question mean column or text rather column in table. in document, should able following values: // ... var sectionproperties = body.getfirstchild<sectionproperties>(); // pagesize contains width , height properties var pagesize = sectionproperties.getfirstchild<pagesize>(); // contains information surrounding margins var pagemargin = sectionproperties.getfirstchild<pagemargin>(); // contains information spacing between neighbouring columns of text // can useful if use page layout multiple text columns var columns = sectionproper
