i use alarmmanager set repeating alarm each widget updating purposes. it's working well, on devices. in order re-establish alarms after reboot, relying on onenabled() method, since called once group of app widgets. , in that, have following: alarmmanager alarmmanager = (alarmmanager) context.getsystemservice(context.alarm_service); appwidgetmanager appwidgetmanager = appwidgetmanager.getinstance(context); int appwidgetids[] = appwidgetmanager.getappwidgetids(new componentname(context, myappwidgetprovider.class)); (int appwidgetid : appwidgetids) { // call function set repeating alarm widget (including doing widget update now)... updateappwidgetalarm(context, appwidgetid, appwidgetmanager, alarmmanager); } whilst seems work in cases, appears devices onenabled() method not doing @ all. know being called, logging put in, nothing happening. i suspect maybe appwidgetids array empty, because @ time after reboot list has not yet been populated. put in more log

i have mod_wsgi, daemon mode, , django. i make mod_wsgi run code @ startup if provide application-group , process-group params wsgiscriptalias - https://stackoverflow.com/a/20930912/203485 (instead default it'll run on first request). but how make run same startup code after reloads workers automatically after wsgi file changes (you upload new files , touch wsgi file)? won't run startup code until first request. i need heavy initialization after workers start , preferably without server reload (it requires root). you can call function @ module scope of wsgi script.

i seem stuck in construction of page objects. read lot of docs page objects , know contain 2 things: elements present on page functions interact page when check example files see elements defined in beginning of each page object. in test, pageobject imported via require. problem see there objects aren't yet present when require happens. there way solve without having require when page loaded? thanks inadvance. regards there new protractor style guide coming (currently in review), should clear things lot, page object creation , requiring part. here current draft: protractor style guide regarding question, first of all, page objects need defined functions, declaring page object elements in constructor: var questionpage = function() { this.question = element(by.model('question.text')); this.answer = element(by.binding('answer')); this.button = element(by.classname('question-button')); this.ask = function(question) { t

i have code $str = ''; foreach ($_post $k => $v) { $str .= $k.'='.$v; } is possible make same chttprequest ? didn't find method it. need md5 in end, there no security issues. i dont think chttprequest intended post data, yii uses $_post variable, gii's default output example can this: public function actioncreate() { $model=new model; // uncomment following line if ajax validation needed // $this->performajaxvalidation($model); if(isset($_post['model'])) //<- post data var { $model->attributes=$_post['model']; //<- post data var if($model->save()) $this->redirect(array('view','id'=>$model->id)); } $this->render('create',array( 'model'=>$model, )); }

i try move graph in jgraphx. first try use setgeometry, moves entire coordinate system , origin. no option me, because bit tricky when moving several graphs. my second try with object[] ver = graph.getchildvertices(graph.getdefaultparent()); graph.movecells(ver, 100, 100, false); moves cells. far good, edges start , end points change positions. after moving cells: before moving cells, edges have correct position. so how can set position of edges normal start , endpoints? alternatively, appreciate other approach move cells given position. edit: seems behaviour occurs, if add layout before. without layout, moving cells works expected. mxgraph graph = new mxgraph(); object parent = graph.getdefaultparent(); graph.getmodel().beginupdate(); try { object v1 = graph.insertvertex(parent, null, "hello", 20, 20, 80, 30); object v2 = graph.insertvertex(parent, null, "world!", 240, 150, 80,
