i'm writing console app uses lots of async methods; i've made async main method can await in: static void main(string[] args) { mainasync(args).wait(); } static async task mainasync(string[] args) { // can use await here } however, when exception occurs; debugger break me on .wait() call. not experience. is there can debugger breaks exception occurs rather here? i'm using vs2015 , targeting .net 4.6 if influences answer.

this question has answer here: does c# 6.0 work .net 4.0? 3 answers i have project targets older versions of .net framework (.net 4.5.2). installed visual studio 2015 (and therefore .net 4.6 on machine). noticed if use c# language features released in .net 4.6/c# 6, still compiles. if project's target framework < .net 4.6, shouldn't not compile: public string myexpressionbodyproperty => "1"; //auto properties new in c# 6 public string myautoproperty { get; } = "1"; private static void methodthatusesnameof(string filename) { if (filename == null) { //nameof released in c# 6 throw new argumentexception("the file not exist.", nameof(filename)); } } how can ensure i'm using .net language features work framework version i'm targeting? ...

is there way pass object property function reference instead of value? es5 properties can have getters , setters. how pass variable uses getters , setters instead of result of getter? right have pass reference whole object, not single property want. is there way pass object property function reference instead of value? no. in fact doesn't make lot of sense "pass object property", notion of "property" doesn't exist without entity property of. if matter of encapsulation , not wanting leak full control, can creative. e.g., var obj = { sensitive: 'do not share me!', public: 'hi there', setpublic: function(val) { this.public = val; } }; function somefunction(setter) { setter('new value'); } somefunction(obj.setpublic.bind(obj));

i have 2 images of printed circuit boards (pcb) both showing same pcb. differences between them lighting, scale , orientation (because take pcb images phone camera). now want use 1 image of pcb check if components of circuit assembled on identical pcb. is there convenient way check differences between 2 images of 2 identical pcb? btw, can add marks on pcb in opencv can correct orientation , scale of image. pcb = printed circuit board, right?!? you compute projective projective transformation or homography between matched points in both images. transformation can used match planes (like pcbs) , considers scale, rotation, shear , projective changes between images. it's simple method: select @ least 4 points , solve system of linear equations. take @ answer question on math se explains that. this opencv example uses (automatic) feature matching find corresponding image points , computes homography. the interesting derivation of transformation can found ...

so i'm trying script working tshark on centos 7 server, i'm having problems. script works fine on windows laptop, put in plugins folder in appdata, can't find similar location on linux. used yum download wireshark, , have program in of folders, can't find either of init.lua files or plugins folder. when use tshark -v tells me built "with lua 5.1" know that's not problem, have no idea go here. suggestions? sadly centos, fedora, oracle linux, , rhel (as of today) not include init.lua in packaging of wireshark. "init.lua" must reside in wireshark directory (e.g. /usr/share/wireshark) before wireshark active lua scripts.

i have stupid question - how can stop debugging? i run adplus -crash -0 path -pid number -mss symbols .. then got message attached process. saw logs , mini dumbs in folder, want stop it. should do? not see commands in adplus detach process. how can it? can close cdb.exe command window or not? thanks you can break debugger (in cdb window, hit ctrl+c) , detach using qd command. you might want consider using procdump capture crash dumps -- more flexible, easy use, , supports both x86 , x64 processes in single package.

my data consists of simple information contracts. simplified each 1 looks this: { "id": 1234567890, "district": "districtname", "city": "cityname", "test": "testnumber", "date": "2015-03-15", "score": 0.0 - 1.0 } i have simple dc.barchart number of tests per day , dc.rowchart districts , 1 cities filter displayed data crossfilter. what need line chart plots every score of every contract in ascending or descending order. mean not want group data score plot every score on y-axis , have nothing on x-axis. assuming data plotted in ascending order resulting picture ever increasing graph. see below: how do data lives inside crossfilter instance, dc.js , d3.js?
