i'm building meteor app let's user organize lists of items in tags. i use jquery draggable , droppable update collection when user drags item 1 tag another. i find hard understand how/where/when should call function. i've tried few different options (including this "hacky way of doing it". the blaze documentation mentions functions can called on dom events, lacks drag , drop events i'm looking for. i've settled on calling function under template.rendered, means item can dropped once per render. i've tried counter tracker.autorun, don't think understand how works , item can still dropped once per render. how can make .item draggable several times per render? template.tag.rendered = function () { //wait on subscriptions load if (session.get('data_loaded')) { tracker.autorun(function () { $(".item").draggable({ revert: true, start: function (event, ui) { var movingitem = blaze.g

i have been experimenting different ways of doing dynamic actor , group lookup. implementing custom usergroupcallback. authorization tricky since not conform standard jaas model. each user has role (assistant, administrator, officer); however, role specific department , functionality department. example, can assistant in hr department, have permission use time keeping functionality. in initial experiment, created service task had inputs role, department, , functionality permissions. perform lookup determine users meet criteria , return comma separated string users. save string process variable , set actor list user task #{approvedusers}. approach works, dislike having predefined user list since role permissions change time task acted upon. the next logical step generating dynamic comma separated list of group ids. since group needs single string, concatenated of possible attributes role. using previous example, user's role become 'assistant_hr_timekeeping'. able wor

i haven't used c in last few years. when read this question today came across c syntax wasn't familiar with. apparently in c99 following syntax valid: void foo(int n) { int values[n]; //declare variable length array } this seems pretty useful feature. there ever discussion adding c++ standard, , if so, why omitted? some potential reasons: hairy compiler vendors implement incompatible other part of standard functionality can emulated other c++ constructs the c++ standard states array size must constant expression (8.3.4.1). yes, of course realize in toy example 1 use std::vector<int> values(m); , allocates memory heap , not stack. , if want multidimensional array like: void foo(int x, int y, int z) { int values[x][y][z]; // declare variable length array } the vector version becomes pretty clumsy: void foo(int x, int y, int z) { vector< vector< vector<int> > > values( /* painful expression here. */); } the slice

the situation this, trying use php connection connect mysql database on phpmyadmin. nothing fancy connection trying see whether connection successful or not. using mamp host database, connection trying use this: <?php $servername = "127.0.0.1"; $username = "root"; $password = "root"; try { $conn = new pdo("mysql:host=$servername;dbname=appdatabase", $username, $password); // set pdo error mode exception $conn->setattribute(pdo::attr_errmode, pdo::errmode_exception); echo "connected successfully"; } catch(pdoexception $e) { echo "connection failed: " . $e->getmessage(); } ?> i have been using postman test see if connection working, keep receiving error message: connection failed: sqlstate[hy000] [2002] connection refused before receiving error message of: connection failed: sqlstate[hy000] [2002] no such file or directory this because had set servername localhost, through cha

i've image: edit sorry had remove images! i need extract contour of non-black picture, used findcontour cv_retr_external parameter, obtain this: here's code: static mat canny_output, grey,draw; vector<vector<point>> contours; cvtcolor(final_img, grey, cv_bgr2gray); canny(grey, canny_output, 100, 200); findcontours(canny_output, contours, cv_retr_external, cv_chain_approx_simple); draw = mat::zeros(canny_output.size(), cv_8uc3); (size_t = 0; < contours.size(); i++) { drawcontours(draw, contours, i, scalar(255, 0, 0)); } how can resolve? simply add binarization minimal threshold, , remove canny: cvtcolor(final_img, grey, cv_bgr2gray); //threshold=1: low value, anyway rest of image pure black threshold(grey, binary, 1, 255, cv_thresh_binary); findcontours(binary, contours, cv_retr_external, cv_chain_approx_simple);

i've been struggling getting django , aws work together. i'm following tutorial here: https://realpython.com/blog/python/deploying-a-django-app-to-aws-elastic-beanstalk/ i've been following tutorial steps, including using "eb option" command change wsgipath, keep getting error: "error: wsgipath refers file not exist." as far can tell i've been doing according tutorial. the relevant part of config file looks this: numprocesses: '1' numthreads: '15' staticfiles: /static/=static/ wsgipath: iotd/iotd/wsgi.py what doing wrong? i have read realpython blog post referred to. refer aws tutorial. written deployment of bare bones django project , can found at: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html#python-django-configure-for-eb i found useful work through, , learned great deal fixing error have identified. of course fix related own implementation of tutorial, followe

for application working on, have usercontrol added form programatically several times. part of usercontrol richtextbox set transparent , has click functionality disabled acts more label , blends user control. when user control deliberately clicked user, richtextbox's background changed white, isreadonly set false, , clicking enabled. the problem trying correct user still has click on richtextbox second time enable caret prior typing. googling , code attempts programatically set caret haven't worked. suggestions why below code isn't working? there else need do? contentbox.ishittestvisible = true; contentbox.background = new solidcolorbrush(color.fromrgb(240, 240, 240)); contentbox.isreadonly = false; //manage caret position textpointer newpointer = contentbox.caretposition; newpointer = newpointer.documentend; contentbox.caretposition = newpointer; i think missing setting logical , keyboard focus control afterwards. try dispatcher.begininvoke(

i have developed sql generate statistics on our local tickets database table (sql server 2008). can see code, want select tickets, joining group group name, grouping group code year/month. i want create totals (counts) how many tickets open, closed, closed outside of sla (past due date), , sla%. this code works, i'm not happy having code nested (select counts); seems not strategy multiple re-scans. is there better design generating multiple "counts" columns single select on table ... or standard approach? select g.group_name [group], year(tm.date_open) year, month(tm.date_open) month, count(*) [tickets opened], (select count(*) tickets tm2 tm2.group_code = tm.group_code , year(tm2.completion_date) = year(tm.date_open) , month(tm2.completion_date) = month(tm.date_open) ) [tickets closed], (select count(*) tickets tm2 tm2.group_code = tm.group_code

i 'm having form on can create new "book". book, can add tags (e.g. describe additional information it). the relation between book , tag manytomany, because each book can have many tags, , each tag can rely different books. (each tag unique field on name). so, when user enters new tag book not exists in database, want create tag when submitting. if exists, want add tag book. i've tried following: $book = $this->form->getdata(); foreach ($tags $tag) { $tag = strtolower($tag); // check if tag exists $tagentity = $this->em->getrepository('bookbundle:tag')->findbyname($tag); // if not, create new tag , add if(null === $tagentity) { $tagentity = new tag(); $tagentity->setname($tag); } // add tag book $book->addtag($tagentity); // add book tag $tagentity->addbook($book); // create relation between tag , book $this->em->persist($book); $this->em->persist($tagentity); $this->
