i'm trying process id associated current tab thru chrome extension. i did manage thru chrome.processes experimental api. there way tab pid standard (non-experimental) api ? if want real process id (i.e. 1 can used other programs identify processes), option chrome.processes , api available on dev channel (so not chrome stable nor beta). if need identifier uniquely identify processes, can "process id of tab" via chrome.webnavigation api. id meaningful within chrome. before delve details, let's first multiple tabs can share same process id, , 1 tab can contain multiple processes (when site isolation project enabled). so, "tab pid", assume you're referring process hosts top-level frame. can retrieve list of frames , extract process id tab follows: background.js 'use strict'; chrome.browseraction.onclicked.addlistener(function(tab) { chrome.webnavigation.getallframes({ tabid: tab.id, }, function(details)

there may or may not duplicate question, although tried find 1 everyone's answer seemed referring declaration/prototype . specify definition void foo() { } same void foo(void) { } , way should use? in c89? in c99? believe should start using void foo(void); prototype declarations, there difference @ if use void or not definition ? i'll try answer , practically. practice , reference i'm familiar with, c89 , c99 should treat declaration/definition/call of functions which take no arguments , return no value equally. in case 1 omits prototype declaration (usually in header file), definition has specify number , type of arguments taken (i.e. must take form of prototype , explicitly void foo(void) taking no arguments) , should precede actual function call in source file (if used in same program). i've been advised write prototypes , decently segmented code part of programming practice. declaration: void foo (void); /*not void foo(), in order conform

we have asp.net web api application, in used architecture: presentation layer bll layer dal layer we discussed, me , colleges, tdd , how can used in our project : my approach i see have test bll layer adding full unit tests list, then test presentation layer other opinion we have test services(presentation layer). if test failed then, test methods(in bll) have relation service so discussion proper vs optimized way so need know what best approach between them? can size , type of project interfers in comparison? thanks, in bl, dal should injected dependencies , should using dependency injection container unity. reason being, unit tests shld have no dependency databases. when bl tests isolated databases tests can run fast too

i think code better show, want do: update set a.[changed] = 1 [dbo].[table1] inner join [table2] e on [a].[part] = [e].[activepart] update [dbo].[table1] [range] = [range] [partgroup] = [partgroup] , [changed] > 0 before update: after update: please help. thank much. greetz vegeta_77 yes, first part looks better (even if think isn't needed, since concerns same column joining on). nevertheless, second update shouldn't produce changes: update [dbo].[superliste_000] set [plan-tgrp-spanne_stfl1] = [plan-tgrp-spanne_stfl1], [plan-tgrp-spanne_stfl2] = [plan-tgrp-spanne_stfl2], [plan-tgrp-spanne_stfl3] = [plan-tgrp-spanne_stfl3], [plan-tgrp-spanne_stfl4] = [plan-tgrp-spanne_stfl4] [teilegruppe] = [teilegruppe] , [date_change] > 0 again update [plan-tgrp-spanne_stfl1] [plan-tgrp-spanne_stfl1] - same value... either tired , misinterprete code or there little bug in update. ;-)

my issue when check checkbox turns checked duplicates checked state next listview item isn't on visible list (e.g. when can see item on positions 0-5/6 on 1 screen element on position 7-8)... this onclick method: viewholder.messageselectbox.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { if (viewholder.messageselectbox.ischecked()) { log.i("itemid", string.valueof(getitemid(position))); log.i("position", string.valueof(position)); mlistofitemstodelete.add(position); collections.sort(mlistofitemstodelete); collections.reverse(mlistofitemstodelete); } else { (int = 0; < mlistofitemstodelete.size(); i++) { int pos = mlistofitemstodelete.get(i); if (pos == position) {

i'm trying exploit motion data. i've created test app using motionkit framework . print(teststring) prints x variables correctly console in 1 second interval. testlabel not updated once. import uikit import motionkit class viewcontroller: uiviewcontroller { @iboutlet weak var testlabel: uilabel! let motionkit = motionkit() override func viewdidload() { super.viewdidload() motionkit.getaccelerometervalues(1.0) { (x, y, z) -> () in let teststring = string(x) self.testlabel.text = teststring print(teststring) } } override func didreceivememorywarning() { super.didreceivememorywarning() } } what missing? appreciated. just wrap textfield text code in dispatch_async dispatch_async(dispatch_get_main_queue(), ^{ self.testlabel.text = teststring });

i working on project mates. yesterday cloned project intention add functionality. have 2 local branches develop (the main branch) , pagecontent (my feature branch). the problem encountering when edit on feature branch, automatically edits on developp branch (i did not commit anything). i checked out on developp branch delete edition , when checked out on feature branch, edition deleted ... the branches seem auto-synchronised. i checked out on develop branch delete edition , when checked out on feature branch, edition deleted ... this how git works . in following diagram can see 3 states . git has 3 main states files can reside in. they shared between branches. when checkout branch change head end staging area && working directory shared between repository when checkout branches. since did not commit (i assume happened) when switch branches see changes following new branch. if don't want changes follow you need commit (or stas
