say have file used n readers , m writers. when know n , m's value, if n==3 , m==1, write code this: (use 'clojure.java.io) (with-open [rdr1 (reader file) rdr2 (reader file) rdr3 (reader file) wtr1 (writer file)] (time-to-work-out-guys)) now case is, app user determines values of n , m, have no idea value n , m have. there way still can use with-open initialize readers/writers , job? because open-with macro instead of function, way build macro generates call open-with , use eval compile @ runtime. while technically answer yes, can't recommend doing so . open-with convenience not fit cases. in case makes more sense write own (try .... (finally ...)) statement.

i trying develop functionality using qt don't know whether possible implement. here requirement: when user hovers on node (an object derived qgraphicsitem), window shown near node, in window there might histograms or buttons can clicked show further information. when mouse leaves window, automatically close. i tried use tooltip, because can pop-up near node , close when mouse leaves it, can show text. so, still cannot work way. wondering if there way this? did lots of google search, there still no answer. thanks helping me this. if you're ok using 3rd party library, qxt provides class provides tooltip qwidget based, let use arbitrary widget tooltip rather text. see: qxt::tooltip

char c[] = "hello"; char *p = "hello"; printf("%i", sizeof(c)); \\prints 6 printf("%i", sizeof(p)); \\prints 4 my question is: why these print different results? doesn't c[] declare pointer points first character of array (and therefore should have size 4, since it's pointer)? it sounds you're confused between pointers , arrays. pointers , arrays (in case char * , char [] ) not same thing. an array char a[size] says value @ location of a array of length size a pointer char *a; says value @ location of a pointer char . can combined pointer arithmetic behave array (eg, a[10] 10 entries past wherever a points) in memory, looks (example taken the faq ): char a[] = "hello"; // array +---+---+---+---+---+---+ a: | h | e | l | l | o |\0 | +---+---+---+---+---+---+ char *p = "world"; // pointer +-----+ +---+---+---+---+---+---+ p: | *======> | w | o | r | l | d |\0

i've been trying figure out hours, can't seem working. json file being loaded in "friends" collection won't populate in view. var friend = backbone.model.extend({ defaults: { "name": "unknown", "job": "unknown" } }); var friend = new friend({ }); var friends = backbone.collection.extend({ model: friend, url: '/friends.json', initialize: function() { this.fetch(); } }); var friends = new friends(); var friendsview = backbone.view.extend({ tagname: "ul", template: _.template('<li><%= name %> <%= job %></li>'), render: function(){ this.$el.html(this.template(this.model.tojson())); } }); var friendsview = new friendsview({ model: friend }); friendsview.render(); $('#here').html(friendsview.el); the json looks this: { "name": "timmy", "job": 'sky

in play ws library, using call process streaming http response: def get[a](consumer: responseheaders => iteratee[array[byte], a]): future[iteratee[array[byte], a]] i passing like: _ => (iteratee.foreach(chunk => println(chunk))) everything works fine, @ point connection seems close , don't know how handle this. tried adding .mapdone print out stuff when iteratee done, never happens. on request, how can detect connection has been closed , handle event? it seems not longer problem in play 2.2.3. function passed map defined below should invoked unit when stream closes: val connection = ws.url("http://example.com") .get(_ => iteratee).flatmap(_.run) map { _ => println("closed") }

i've created iframe in page here it's code: var frame = document.createelement('iframe'); frame.setattribute('src',''); document.body.appendchild(frame); if(document.addeventlistener){ frame.addeventlistener('load', callback, false); } else { frame.attachevent('onload', callback); } function callback(){ alert('test'); } it works fine in ff no thing alerted in ie, why? note use ie10 in win8 you need move document.body.appendchild() after addeventlistener() call var frame = document.createelement('iframe'); frame.setattribute('src',''); if(frame.addeventlistener){ frame.addeventlistener('load', callback, true); } else { frame.attachevent('onload', callback); } document.body.appendchild(frame); function callback(){ alert('test'); }

at beginning sorry bad english. jquery v2.0.0 in google chrome, mozilla firefox, opera last versions today had problem timer_multy_update = setinterval( function() { $.get( 'test.php', function (result){ parseandupdatedata(result); }, "json" ); }, 500) the problem if server hangs (i don't know how correctly), i.e. time answer server more 0,5 second, timer not stay , continues send request, before server answer can send 2-4 request, answer return little time and, problem, in firebug request correct, variable result contains 1 answer first answer server. maybe did not express myself clearly, want 2-4 request server return different answer, in result gets 2-4 times first answer server, , big problem. i tried find information on internet, found nothing. i not know why first thought error in jquery, began @ source code, , found mention heder , it's hashes. try chan

i writing program can encrypt text file. first need ask users file name. did like: char file_name[50]; fgets(file_name, 50, stdin); but didn't work. how can this? i confused if store file name in char array has, say, 50 elements, file name has 10 characters. when pass array or pointer fopen , program going remaining 40 elements of array? storing value? passed fopen ? in c, string \0 terminated sequence of characters. long there \0 within 50 bytes of file_name , file_name contains valid string fopen() . the reason fopen() failed name passed had \n in after reading input. because fgets() stores newline character buffer. have remove before using string file name. char *p = strrchr(file_name, '\n'); if (p) *p = '\0';

i had developed complex enough canvas web application using kinetic.js year ago. used kinetic.js 3.10.4. version , i'm surprised application not work anymore on latest browser google chrome , mozilla firefox. example, there error while creating text shapes. here stack trace error google chrome debugger: uncaught typeerror: type error kinetic.shape.kinetic.node.extend.fill config.drawfunc kinetic.shape.kinetic.node.extend._draw kinetic.container.kinetic.node.extend._drawchildren kinetic.layer.kinetic.container.extend._draw kinetic.layer.kinetic.container.extend.draw loadmenu _background.onload i've tried using 4.6.0 version there deprecated functions , features on legacy code. wondering using current 3.10.4 version library (with several effortless fix) rather update 4.6.0 version . still possible that? in advance :) yes, transitions eliminated , have been replaced tweens effective kineticv4.5. tweens coded old transitions. so recoding of transitions

i have table 3 columns a(, b, c) , have 2 constraints a , b should jointly unique have done defining unique constraint. for given value in a, there can 1 true in c. (a, c=true) has unique. need in defining second constraint. e.g data set a : b c a1 : b1 : false a1 : b2 : true a1 : b3 : false a2 : b1 : true a2 : b2 : false a2 : b3 : false i don't think can expressed in database-portable way without changing schema. partial index can this: create unique index one_c_per_a_idx on table(a) c; but available on postgresql , sql server (and simulated functional index on oracle). postgresql back-end can use postgresql_where keyword argument index (see docs ) define partial index in sqlalchemy. a portable way split @ least 2 tables, converting explicit boolean column implicit "prese

i have following design problem, , hope me solve :) i have view controller takes questionnaire model instance , render questionnaire using collectionview. questionnaire model contains array of questions models (each question instance different subclass of base question class depending of answer type, example : date question, boolean question...). each cell in collectionview represent question , contain answer views loaded .xib depending on answer type (1 xib = 1 type of answer). answer view may contain uiswitch, uitextfield or other control allow user answer question. at moment answer view configure control depending on answer validation rules (for example date question may have datepicker minimumdate/maximumdate properties configured depending on in date question model, or correct keyboard textfields etc...). answer view delegate/observer/target of control, , when value change, view set value (using formatter if needed , depending on answer type) in destination object. think

i'm trying follow railstutorial guide, doing own application instead. have trouble section 7, forms. my controller : def update d = deck.find(params[:id]) d.title = params[:deck][:title] d.slug = params[:deck][:slug] d.category = params[:deck][:category] if d.save redirect_to deck_path(d), notice: "deck saved successfully" else render :edit end end i know it's very, far code, refactor later (if have suggestion i'm ears, use rails 3, guess strong parameters of rails 4 out). the problem when d.save not work (due validation), render :edit . right now, when enter invalid data, tries redirect show action, , crashes because not have data display. if add @deck = d above render , works, url still show action. if validation fail, how can stay on same url , display error messages ? "change url render same page" behavior accepted valid ? thanks ! if you're interested in looking @ rest of cod

i have application collects information customers using asp application in website. application writes information database (sql server) in remote server (web server). want information in database updated local pc in real time i.e. data added web server db same should downloaded local server (offline server). summarize want push notification of data changes web server local pc. there numerous ways accomplish - choose depends on constraints of particular situation. simplest have local application poll server @ regular intervals. crude has advantage work without modification router/firewall settings. alternatively write code on asp application send message local application when change occurs. true push, fail without port forwarding on router; if can configure router, code should straightforward enough. question vague answer here - replies saying 'ok , bit stuck with?', 'what have tried?' etc
