this question has answer here: why write “.call(this)” @ end of javascript anonymous function? [duplicate] 4 answers what kind of design pattern , significance of using closure?

(function(){ // code here })(); thats invoked function expression. more info here: http://benalman.com/news/2010/11/immediately-invoked-function-expression/ the purpose run code while protecting scope (so variables declared within don't leak out global scope. update call sets value of this function being applied on. without it, value set window object, there set outer scope.

here issue : i've localized application in arabic. (it's different regular localization, have different targets, 1 each language). on simulator, view flipped, auto-layout , leading / trailing part of constraints, can't seem same result on device. autolayout + rtl + uilabel text alignment shows example of flipped view on simulator. i've found indication supported in auto-layout guide : « the attributes leading , trailing same left , right left-to-right languages such english, in right-to-left environment such hebrew or arabic, leading , trailing same right , left ». lets me think supposed flip view, on simulator. i use -applelanguages (ar_sa) in scheme on simulator, flips view, fail find proper setting in device same thing. setting language , region format arabic doesn't seem much. on iphone 4s, ios 7.0.4 tldr: setting should change on actual iphone device in « arabic environment » , have flipped view, or missing flips in simulator not on device ?

i have 2 tables follows: table a docnumber line amount doctype 1000 1 100 3 1000 2 200 3 1001 1 300 5 table b docnumber debit credit account 1000 100 0 5410 1000 200 0 5560 1001 0 300 6790 i'm trying create select looks this: docnumber line amount account 1000 1 100 5410 1000 2 200 5560 1001 1 300 6790 so, logically, i'm trying figure out way join a.amount b.debit a.doctype = 3 , join a.amount b.credit a.doctype = 5 as can see, i'm novice appreciated assuming sql server. assuming docnumber intended play role in join well, despite not being explicitly stated in question. you can use conditions on join want: select a.docnumber, a.line, a.amount, b.account join b on a.docnumber = b.docnumber , ((a.doctype = 3 , a.amount = b.debit) or (a.doctype = 5 , a.amount = b.cre

in code below, second fillstyle overrides color specified in first 1 if use rect() , fill() in both places (ie, both rects green) works expected (ie, first rect being blue , second being green) if change first rect() fillrect() . why so? thought fillrect() rect() , fill() , right? ctx.translate(canvas.width/2, canvas.height/2); ctx.fillstyle = "#5a9bdc"; ctx.fillrect(0, 0, rectwidth, rectheight); // ctx.rect(0, 0, rectwidth, rectheight); // ctx.fill(); ctx.translate(-canvas.width/2, -canvas.height/2); ctx.fillstyle = "#31b131"; ctx.rect(0, 0, rectwidth, rectheight); ctx.fill(); tested in chrome | fiddle fillrect .fillrect "stand-alone" command draws , fills rectangle. so if issue multiple .fillrect commands multiple .fillstyle commands, each new rect filled preceeding fillstyle. ctx.fillstyle="red"; ctx.fillrect(10,10,10,10); // filled red ctx.fillstyle="green"; ctx.fillrect(20,20,10,10); // fille

i following guide https://developers.facebook.com/docs/ads-for-apps/mobile-app-ads , i've done explained: added facebook sdk, triggered "app activate" event corresponding app id in app delegate, set info.plist id. when test application through simulator , on testing device open app dashboard -> insights -> app events -> overview , track of "fb_mobile_activate_app" events instantly, incrementing. should have know sdk implemented correctly , can update app on app store without worries , run ads campaign on facebook? asking because things bit confusing on insights -> "mobile app installs" page: this dashboard shows organic , paid app installs reported either facebook sdk ios, facebook sdk android, or mobile measurement partner. dashboard serves as indicator of app install volume, user demographics, , baseline understanding how ads increasing installs of app. developers can use dashboard debugging ensure app installs being recorded.
