angularjs - CSS transition not correctly working -

i have weird problem. have css flip animation 2 images.

the problem on first transition, image hidden first not transition instead shows instantly @ end of transition.

however, after first transition problem disappears , working correctly afterwards.

though application written in angularjs, think css problem. how solve this?

i've created fiddle explains problem:

c++ - Does derived class allocate memory for member variable? -

c++ - Does derived class allocate memory for member variable? -

#include<cstdio> #include<iostream> using namespace std; class { public: int x; }; class b: public { }; int main() { b b; b.x=5; cout<<b.x<<endl; homecoming 0; }

i have above code.it's okay.but want know when inherit class b class fellow member variable x declared in class b or class b access fellow member variable x of class ? there 2 variables same name in 2 different classes or there 1 variable , objects of both classes have access ? if there 2 different variables same name in 2 different classes why, when object of derived class declared constructor of base of operations class called ?

when create object of derived class, base of operations class sub-object embedded in memory layout of derived class object. so, question, there's on variable part of derived object. since, taking non-static members here, each derived object gets base-class sub-object laid out in memory. when create base of operations class object, different piece of memory representing different object , has nil derived object created earlier.

hope clarifies doubt!

obd ii - OBD ll (elm327) data exchange over Bluetooth -

i develope android application can read(and send) info obd2 , show in real time. question optimal frequency reading info , sending commands obd? example, when create initialization of obd 4 commands 1 after another, init fails. can executed successfuly... if create init 500ms delay between commands ok. now, when send command obd, how much time suppose wait reply sure getting ok? there way know or seek different delays in real time? thanx

optimal frequency sending commands depends on obd-ii device, depends on auto using. not create much sense optimize that. take safe time when testing , play hard-coded delay.

a improve way solve this, send command. wait response, obd-ii device busy handling command. when receive response, that's trigger utilize send next command in queue.

the obd-ii device handles 1 command @ time, more stable , effective method send data.

java - retain specific elements in an array from an array that are in another array -

java - retain specific elements in an array from an array that are in another array -

let's have 2 array;

integer[] array= { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 200, 5, 6, 5 }; integer[] array2= { 12, 2 ,3, 2, 200, 5 };

im trying create method homecoming array element removed except in nowadays in array2, output of method should be

{2 ,3, 5, 200, 5, 5 }

i dont want utilize info construction , have no thought how code im trying do, im not sure how can determinate resulting array length

thanks

if understand question, begin creating contains(integer[], integer) method. iterate array , homecoming true if array contains value.

private static boolean contains(integer[] a, integer v) { (integer t : a) { if (t.equals(v)) { homecoming true; } } homecoming false; }

then can leverage iterate arrays twice. 1 time perform count, , sec time populate newly created array count number of elements. like,

public static integer[] retainall(integer[] a, integer[] b) { int count = 0; (integer val : a) { if (contains(b, val)) { count++; } } integer[] out = new integer[count]; count = 0; (integer val : a) { if (contains(b, val)) { out[count++] = val; } } homecoming out; }

then test it,

public static void main(string[] args) { integer[] array = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 200, 5, 6, 5 }; integer[] array2 = { 12, 2, 3, 2, 200, 5 }; system.out.println(arrays.tostring(retainall(array, array2))); }

output requested

[2, 3, 5, 200, 5, 5]

of course, utilize arrays.aslist(t...) , retainall() like

public static integer[] retainall(integer[] a, integer[] b) { list<integer> al = new arraylist<>(arrays.aslist(a)); al.retainall(arrays.aslist(b)); homecoming al.toarray(new integer[al.size()]); }

multithreading - CSemaphore in MFC C++ doesn't work -

multithreading - CSemaphore in MFC C++ doesn't work -

i'm trying create semaphore multiple threads, need run 1 thread @ time. i'm declaring semaphore in dialog file

ghsemaphore = createsemaphore(null, 1, 1, null); // 1 thread @ 1 time

before start tread call

waitforsingleobject(ghsemaphore, 0l);

before thread ends call:

releasesemaphore(ghsemaphore, 1, null);

it starts treads instead of 1 tread once. thought please ? lot!

you "before start thread..(you acquire semaphore)" - in same (main) thread? think, semaphore restrict acquisition one thread (which here main thread), acquisition needed placed within (child) threads, allow 1 of them run concurrently.

you have create single 1 semaphore in parent thread , pass reference kid threads. 1 time 1 kid thread released wait..() semaphore blocks concurrent threads until first 1 releases semaphore , next kid thread allowed run. however, kid threads run concurrently until phone call of wait..().

btw: why create multiple threads if want 1 thread run @ time (until terminates)?

regarding scope create semaphore: info provided looks ok have 1 single semaphore @ application level. however, recommend pass kid threads parameter @ thread start (instead of referring global variable), kid threads independent of selection of scope. if ever need handle multiple, independent bunches of such kid threads, can switch create 1 semaphore each bunch before created (the other alternative mentioned). if create semaphores on fly, sure release it, 1 time threads have terminated.

so, now, best create 1 application-wide semaphore ("global").

c - Print from pointer? -

c - Print from pointer? -

ok, have assignment gives me constant:

const char *suits[] = {"hearts", "diamonds", "clubs", "spades"};

basically table pointer points 4 words! simple right?

then have import each word table!

so create new table:

char table[30];

in main structure, , want somehow import within word "diamonds"! on pointer's table word on sec place. suits[1].

well when seek print sec word using command:

printf("%s", *suits[1]);

i error. using command

printf("%c", *suits[1]);

i "d", first letter. have ideas on how able print whole word "diamonds", , how can re-create table create in main form?

(i need re-create word suits[1] new table , able print table)

thank much!!!

i'm not clear on mean "copy table", on printing string, can help there.

executive summary: printf("%s", suits[0]); // prints diamonds what string in c, , memory like?

we have code:

const char *suits[] = {"hearts", "diamonds", "clubs", "spades"};

in memory is:

suits[0] -> pointer memory contains {'h', 'e', 'a', 'r', 't', 's', '\0'} suits[1] -> pointer memory contains {'d', 'i', 'a', 'm', 'o', 'n', 'd', 's', '\0'} ...

a string in c refers pointer null terminated piece of memory. when want print string, do:

printf("%s", <a pointer null terminated string>);

in case, pointer found @ suits[0], do:

printf("%s", suits[0]); thoughts on copying table.

if want store string "hearts" in array, perhaps you're looking for:

snprintf(table, sizeof(table), "%s", suits[0]);

or

strncpy(table, sizeof(table), suits[0]);

c# - await not using current SynchronizationContext -

c# - await not using current SynchronizationContext -

i'm getting confusing behavior when using different synchronizationcontext within async function outside.

most of program's code uses custom synchronizationcontext queues sendorpostcallbacks , calls them @ specific known point in main thread. set custom synchronizationcontext @ origin of time , works fine when utilize one.

the problem i'm running have functions want await continuations run in thread pool.

void beginningoftime() { // mycustomcontext queues each endorpostcallback , runs them @ known point in main thread. synchronizationcontext.setsynchronizationcontext( new mycustomcontext() ); // ... later on in code, wait on something, , should go on within // main thread mycustomcontext runs has queued int x = await someotherfunction(); weshouldbeinthemainthreadnow(); // ********* should run in main thread } async int someotherfunction() { // set null synchronizationcontext because function wants continuations // run in thread pool. synchronizationcontext prevcontext = synchronizationcontext.current; synchronizationcontext.setsynchronizationcontext( null ); seek { // want continuation posted thread pool // thread, not mycustomcontext. await blah(); weshouldbeinathreadpoolthread(); // ********* should run in thread pool thread } { // restore previous setsynchronizationcontext. synchronizationcontext.setsynchronizationcontext( prevcontext ); } }

the behavior i'm getting code right after each await executed in seemingly-random thread. sometimes, weshouldbeinthemainthreadnow() running in thread pool thread , main thread. weshouldbeinathreadpoolthread() running

i don't see pattern here, thought whatever synchronizationcontext.current set @ line utilize await 1 define code next await execute. wrong assumption? if so, there compact way i'm trying here?

there mutual misconception await, somehow calling async-implemented function treated specially.

however, await keyword operates on object, not care @ awaitable object comes from.

that is, can rewrite await blah(); var blahtask = blah(); await blahtask;

so happens when rewrite outer await phone call way?

// synchronization context leads main thread; task<int> xtask = someotherfunction(); // synchronization context has been set // null someotherfunction! int x = await xtask;

and then, there other issue: finally inner method executed in continuation, meaning executed on thread pool - not have unset synchronizationcontext, synchronizationcontext (potentially) restored @ time in future, on thread. however, because not understand way synchronizationcontext flowed, quite possible synchronizationcontext not restored @ all, set on thread (remember synchronizationcontext.current thread-local...)

these 2 issues, combined, explain randomness observe. (that is, manipulating quasi-global state multiple threads...)

the root of issue await keyword not allow scheduling of continuation task.

in general, want specify "it not of import code after await on same context code before await", , in case, using configureawait(false) appropriate;

async task someotherfunction() { await blah().configureawait(false); }

however, if absolutely want specify "i want code after await run on thread pool" - that should rare, cannot await, can e.g. continuewith - however, going mix multiple ways of using task objects, , can lead pretty confusing code.

task someotherfunction() { homecoming blah() .continuewith(blahtask => weshouldbeinathreadpoolthread(), taskscheduler.default); }

javascript - If Element ID exists then Hide Other Element -

javascript - If Element ID exists then Hide Other Element -

i have ecommerce website has multiple prices given item. trying set bit of script hide price, if lower cost class nowadays on page.

<table> <tbody> <tr> <td> <font> <div class="product_listprice">199.99</div> </font> <font> <div class="product_productprice">179.99</div> </font> <b> <div class="product_saleprice">159.99</div> </b> <font> <div class="product_discountprice">139.99</div> </font> </td> </tr> </tbody> </table>

essentially need script hide .product_productprice if .product_saleprice exists on page, , hide both .product_saleprice , .product_productprice if .product_discountprice exists.

here's i've come far google digging.

<script type="text/javascript"> $(document).ready(function(){ if ( $(".product_discountprice").size() ) $(".product_saleprice, .product_productprice").hide(); }); }); </script>

however, doesn't seem working. ideas? i'm jquery novice, i'm sure there improve way out there...

// need script hide .product_productprice // if .product_saleprice exists on page... if ($('.product_saleprice').length) { $('.product_productprice').hide(); } // ...and hide both .product_saleprice , .product_productprice // if .product_discountprice exists. if ($('.product_discountprice').length ) { $('.product_saleprice, .product_productprice').hide(); }

update adds new class name, instead of hiding:

if ($('.product_saleprice').length) { $('.product_productprice').addclass('some-class'); } if ($('.product_discountprice').length ) { $('.product_saleprice, .product_productprice').addclass('some-class'); }

objective c - Why does my view controller inside a UIPopoverPresentationController take up the whole screen? -

i in process of upgrading app ios 7 ios 8, , 1 of areas having problem new uipopoverpresentationcontroller. reason, whenever nowadays view controller using class, view controller not appear in popover, instead presents beingness pushed onto nav stack (takes whole screen). i'm sure i'm missing obvious, between apple's documentation , numerous swift answers on missing it. here's code:

-(void)createandsizepopover:(nsstring*)tablename { //create picklist self.picklistpopoverviewcontroller = nil; //note wspicklistviewcontroller uiviewcontroller self.picklistpopoverviewcontroller = [[wspicklistviewcontroller alloc] initwithnibname:nil bundle:nil withpicklistitem:self.densityunits andpicklisttablename:tablename isslimline:yes]; self.picklistpopoverviewcontroller.showsearchbar = no; self.picklistpopoverviewcontroller.modalpresentationstyle = uimodalpresentationpopover; ((wspicklistviewcontroller*)self.picklistpopoverviewcontroller).picklistitemdelegate = self; //size popover nsinteger rowscount = [self.picklistpopoverviewcontroller.allobjects count]; nsinteger singlerowheight = 35; nsinteger totalrowsheight = rowscount * singlerowheight; nsinteger fourrowsheight = 6 * singlerowheight; nsinteger height = (totalrowsheight >= fourrowsheight) ? fourrowsheight : totalrowsheight; cgfloat largestlabelwidth = 0; (wspicklist* pickitem in self.picklistpopoverviewcontroller.allobjects) { cgsize labelsize = [pickitem.name sizewithattributes:@{nsfontattributename: [uifont fontwithname:@"helveticaneue" size:20.0], nsforegroundcolorattributename : [uicolor blackcolor]}]; if (labelsize.width > largestlabelwidth) { largestlabelwidth = labelsize.width; } } cgfloat popoverwidth = largestlabelwidth + 50; [self.picklistpopoverviewcontroller setpreferredcontentsize:cgsizemake(popoverwidth, height)]; } -(void)showorhidepopover:(id)sender withtablename:(nsstring*)tablename { //show/hide popover if (self.popover != nil) { [self.picklistpopoverviewcontroller dismissviewcontrolleranimated:yes completion:nil]; self.popover = nil; self.picklistpopoverviewcontroller = nil; return; } else { [self createandsizepopover:tablename]; } [self presentviewcontroller:self.picklistpopoverviewcontroller animated:yes completion: nil]; self.popover = self.picklistpopoverviewcontroller.popoverpresentationcontroller; self.popover.permittedarrowdirections = uipopoverarrowdirectionright; self.popover.sourceview = sender; if ([sender iskindofclass:[uibutton class]]) { self.popover.sourcerect = ((uibutton*)sender).bounds; } else if ([sender iskindofclass:[uicollectionviewcell class]]) { self.popover.sourcerect = ((uicollectionviewcell*)sender).bounds; } }

i'm ok reply in either objective-c or swift (since need larn anyway). in advance help provided!

after several days of google'ing , testing theories, found several issues in code.

first, presentation cannot come before setting popoverpresentationcontroller. know flies in face of apple's documentation, states seems "counterintuitive" nowadays view controller before setting popover controller, still worked me.

second, implementation of adaptivepresentationstyleforpresentationcontroller: wrong. returning uimodalpresentationpopover should have been returning uimodalpresentationnone follows:

-(uimodalpresentationstyle)adaptivepresentationstyleforpresentationcontroller:(uipresentationcontroller *)controller { homecoming uimodalpresentationnone; }

hope helps else.

java - finding closet value in another list -

java - finding closet value in another list -

please allow me know if question not clear. can provide more info. have next musical notes in arraylist

arraylist<string> noteslist = new arraylist<>(); noteslist.add("a"); //0 noteslist.add("a#"); //1 noteslist.add("b"); //2 noteslist.add("c"); //3 noteslist.add("c#"); //4 noteslist.add("d"); //5 noteslist.add("d#"); //6 noteslist.add("e"); //7 noteslist.add("f"); //8 noteslist.add("f#"); //9 noteslist.add("g"); //10 noteslist.add("g#"); //11

i have 2 sub lists, 1 ascending , 1 descending. both of them contain notes part of noteslist.

arraylist<string> ascendlist = new arraylist<>(); arraylist<string> descendlist = new arraylist<>();

ex:

ascendlist = c, d, e, f#, g //indices in noteslist = 3,5,7,9,10 descendlist = a, c#, e, f, g, g# // indices in noteslist = 0,4,7,8,10,11

i need generate patterns going through ascending list , descending vice versa. example:

d, e (from ascending list), e, c# (from descending list) c,d,e,f#

(ascend), f,e,c#,a (descend)

f e c# (descend), d, e (ascend)

there status doing this. when want connect descending pattern @ end of ascending pattern, need find next note equal or below lastly ascending note, in descending list.

ex: if f# lastly note in 1 of pattern of ascending type, f should first note in descending pattern. if e lastly note in ascending pattern, 1 time again e first note in descending pattern since e nowadays in both ascend , descend. when generate ascending pattern @ end of descending pattern, need find next note equal or higher lastly descending note.

i not figure out how this. 1 method tried go indices both ascending , descending corresponding noteslist , thought of mapping , using map.higherkey, map.lowerkey, etc methods. unable proceed because not map them.

enum note { c, c_, d, d_, e, f, f_, g, g_, a, a_, b; public note above() { homecoming ordinal() != values().length - 1 ? note.values()[ordinal() + 1] : note.values()[0]; } public note below() { homecoming ordinal() > 0 ? note.values()[ordinal() - 1] : note.values()[note.values().length - 1]; } } interface scale { listiterator<note> joinafter(note note); } scale ascending = new scale() { list<note> notes = aslist(c, d, e, f_, g); @override public listiterator<note> joinafter(note note) { homecoming notes.listiterator(notes.contains(note)? notes.indexof(note) : notes.indexof(note.above())); } }; scale descending = new scale() { list<note> notes = aslist(a, c_, e, f, g, g_); @override public listiterator<note> joinafter(note note) { homecoming notes.listiterator(notes.contains(note)? notes.indexof(note) : notes.indexof(note.below())); } };

i'd recomend add together own iterator wrapper phone call previous next in descendingscale (if don't want reason reverse notes there) , more importantly allow infinitely loop through scales.

if school asignment improve stick numbers , don't mess lists of strings untill need print things out. btw array improve selection here.

Is there any negatives to storing JSON in MySQL? -

Is there any negatives to storing JSON in MySQL? -

i building complex ordering scheme , struggling whether should store of more detailed info in single column json or if should create multiple tables , logic maintain json out of picture.

since each order have multiple required dates, ship dates, parts, kits (collections of parts), , more. seems easier store json of single 'order'row.

are there major downwards sides doing this?

json geared more towards short term storage send info 1 thing another. horribly inefficient space , computationally wise long term storage compared database. loose ability query info straight without parsing first (e.g "select * table orderdate < today"). you'll have develop own tools view data, since if seek view in database directly, run together.

in short, bad idea.

here code:

class base1{ public: base1(){} virtual ~base1(){} }; class d1:base1{ }; class d2:base1{ }; class base2{ public: base2(){} virtual ~base2(){} virtual base1 * fun() = 0; }; class _d1:base2{ public: d1* fun(){} }; class _d2:base2{ public: d2* fun(){} };

by way, fresher c++.. plz help..thanks in advance..

assuming trying utilize covariance of homecoming types, attempts valid except fact types must using public inheritance:

class d1:public base1{ // ~~~~~^ }; class d2:public base1{ // ~~~~~^ }; class _d1 : base2{ public: d1* fun(){} // ok now, d1 inherits publicly base1 }; class _d2 : base2{ public: d2* fun(){} // ok now, d2 inherits publicly base1 };

just can't cast d2* base1* unless using public inheritance, same applies here.

demo

alternatively, have create classes friends, have access private base of operations class:

class _d1; class _d2; class d1 : base1{ friend class _d1; }; class d2 : base1{ friend class _d2; };

c++ standard reference:

§ 10.3 virtual functions [class.virtual]

the homecoming type of overriding function shall either identical homecoming type of overridden function or covariant classes of functions. if function d::f overrides function b::f, homecoming types of functions covariant if satisfy next criteria:

— both pointers classes, both lvalue references classes, or both rvalue references classes

— class in homecoming type of b::f same class class in homecoming type of d::f, or unambiguous and accessible direct or indirect base of operations class of class in homecoming type of d::f

— both pointers or references have same cv-qualification , class type in homecoming type of d::f has same cv-qualification or less cv-qualification class type in homecoming type of b::f.

web scraping - Different results when reading from text file and web in R -

let www.exampleweb.com website info that:

... -3.7358293e+000 7.6062331e-001 6.0701401e+000 -1.6897975e+000 -2.1088811e+000 2.7172791e+000 -2.5477626e+000 ...

1 column 1000 rows. i'm obtaining info website in 2 ways: 1.

con = url("www.exampleweb.com") data_from_html <- readlines(con) close(con)

now need convert data, because

str(data_from_html) chr [1:1000] " -2.9735888e+000" " -1.4757566e+000" " 8.6980880e-001" " 4.9502553e+000" ...

so:

converted <- as.numeric(data_from_html)

copying (ctrl+a) whole site, , pasting .txt file. saving "my_data.txt".

data_from_txt <- read.table("my_data.txt")

now, when utilize

summary(converted) min. 1st qu. median mean 3rd qu. max. -16.2800 -1.5030 -0.0598 -0.1809 1.2220 13.0100

but on other hand:

i can't decide 1 better, sense there info loss in converting char numeric. don't know how prevent it. checked head/tail of these variables, they've got same values:

head(converted) [1] -2.9735888 -1.4757566 0.8698088 4.9502553 -4.3059115 0.9745958 > tail(converted) [1] -3.007217 -4.600345 -3.740255 2.579664 -2.233819 -1.028491 head(data_from_txt) v1 1 -2.9735888 2 -1.4757566 3 0.8698088 4 4.9502553 5 -4.3059115 6 0.9745958 > tail(data_from_txt) v1 995 -3.007217 996 -4.600345 997 -3.740255 998 2.579664 999 -2.233819 1000 -1.028491

how deal it? mean should never web scrap data? if i, reason, can't create .txt file? maybe jest need improve method info conversion?

opencv - How to store image from cam? -

opencv - How to store image from cam? -

i started processing.js.

the goal of programme adept image filter(opencv) video frame.

so thought (however found out not working in way :<) :

get video steam capture object in processing.video package. store current image(i hope can store pimage object). adept opencv image filter call image method filtered pimage object.

i found out how video stream cam, not know how store this.

import processing.video.*; import gab.opencv.*; capture cap; opencv opencv; public void setup(){ //size(800, 600); size(640, 480); colormode(rgb, 255, 255, 255, 100); cap = new capture(this, width, height); opencv = new opencv(this, cap); cap.start(); background(0); } public void draw(){ if(cap.available()){ //return void cap.read(); } image(cap, 0, 0); }

this code video stream , show gets. however, can not store single frame since capture.read() returns 'void'.

after store current frame transform pimage s opencv :

pimage grayness = opencv.getsnapshot(); opencv.threshold(80); thresh = opencv.getsnapshot(); opencv.loadimage(gray); opencv.blur(12); blur = opencv.getsnapshot(); opencv.loadimage(gray); opencv.adaptivethreshold(591, 1); adaptive = opencv.getsnapshot();

is there decent way store , transform current frame? (i think way - means show frame after save current image , transform - uses lots of resources depend on frame rate)

thanks reply :d

not sure want do, i'm sure solved already, useful anyway...

it seems can write capture object's name straight , returns pimage:

cap = new capture(this, width, height); //code starting , reading capture in here pimage snapshot = cap; //then can whatever wanted pimage snapshot.save("snapshot.jpg"); //actually seems work fine cap.save("snapshot.jpg");

c# - How to call Workstation.GetLocalWorkspaceInfo in a way that works for those who use VS2012 and those who use VS2013 without reflection? -

c# - How to call Workstation.GetLocalWorkspaceInfo in a way that works for those who use VS2012 and those who use VS2013 without reflection? -

workstation.current.getlocalworkspaceinfo(string) returns workspaceinfo object associated given local directory.

so, wrote simple programme displays workspace name given local directory name. works great on machine, not work on another.

the difference between 2 mine runs vs2012 , other 1 - vs2013. life of me, cannot understand it. both workspaces linked same tfs server 2010.

after reading tfs api: getlocalworkspaceinfo returns null replaced microsoft.teamfoundation.xxx references ones found on sec machine , worked again. but, of course, stopped working on machine.

it cannot right way. must doing wrong here.

i want single executable work both machines without resorting reflection. question simple - how?

the finish source code can found here - https://bitbucket.org/markkharitonov/tfsinsanity/src. basically, 2 projects sharing same source code, using different set of dependencies.

the main source code is:

private static workspace getworkspace(string wsroot, string wsname, string wsowner) { var coll = new tfsteamprojectcollection(new uri("http://torsvtfs01:8080/tfs/defaultcollection")); var vcs = (versioncontrolserver)coll.getservice(typeof(versioncontrolserver)); workspaceinfo wsinfo; if (wsroot == null) { console.writeline(workstation.current.name); wsinfo = workstation.current.getlocalworkspaceinfo(vcs, wsname, wsowner); if (wsinfo == null) { throw new exception(string.format("failed identify workspace {0};{1}", wsname, wsowner)); } } else { wsinfo = workstation.current.getlocalworkspaceinfo(wsroot); if (wsinfo == null) { throw new exception(string.format("failed identify workspace corresponding \"{0}\"", wsroot)); } } homecoming wsinfo.getworkspace(coll); }

here how works on machine (vs2012):

in case, method signatures should identical, need worry getting proper dll referenced in first place. should able link newer dll , utilize binding redirection load dll users have vs 2012 installed.

we used method in previous product provide tfs 2005 , 2008 compatibility.

in short, create custom assembly resolver. here effort load microsoft.teamfoundation.* dlls vs 2012 when fail load vs 2013 versions linked against:

appdomain.currentdomain.assemblyresolve += new resolveeventhandler(resolveassembly); public static assembly resolveassembly(object sender, resolveeventargs args) { string[] arguments = args.name.split(new string[] { ", ", "," }, stringsplitoptions.removeemptyentries); string assemblyname = arguments[0]; if(assemblyname.startswith("microsoft.teamfoundation.", stringcomparison.currentcultureignorecase)) { homecoming assembly.load(assemblyname + ", version=11.0.0.0"); } homecoming null; }

(note should check requested version number , pass civilization info loader, outlined in blog post, snippet should sufficient started.)

performance - Android Bluetooth LE notifications with 100Hz - missing calls -

i'm developing android app connects bluetooth le device , enables notifications specific characteristic. characteristic notifies smartphone 100hz. assume, oncharacteristicchanged() method called 100 times per second. not case!

using samsung galaxy s5 oncharacteristicchanged() method called 58 times per sec = 42% info loss using samsung galaxy s5 mini oncharacteristicchanged() method called 20 times per sec = 80% info loss using lg g3s = 40% info loss using lg g2 mini = 0.5% info loss (it's quite interesting g2 mini has best "throughput" "low-end hardware" compared other smartphones)

by using performance profiler noticed lg g2 mini smartphone has 6 binders instead of 4. may that's reason why processing notifications - how can number of binders increased?

does know, why android doesn't phone call oncharacteristicchanged() method 100 times per second? why there such huge differences accross various phones? is possible alter @ app or @ phone configuration decrease info loss?

thanks ben

asp.net - Best practices to fill view models with select lists and options for views' reusability in ASP MVC -

asp.net - Best practices to fill view models with select lists and options for views' reusability in ASP MVC -

i'm using view models on models. let's have edit form entity. let's form has field selected drop downwards list. best way fill list used generating drop downwards list? should done in action in controller or maybe in constructor of view model or somewhere else?

my next uncertainty view models "configuring". i'm trying reuse views when have edit form should possible utilize in add together , update scenarios. submit button should execute 2 different actions. okay parametrize view adding view model controller , action names?

finally when have view models storing info - "configuration" quite vast. there pattern logic out of controller? i'm using kind of builders, i'm not sure whether it's enough.

first of excuse me if won't exhaustive topic pretty vast. please read cum grano salis, nil rule written in stone things must adapted case case each specific scenario.

what best way fill list used generating drop downwards list? should done in action in controller or maybe in constructor of view model or somewhere else?

controller method(s). keep model (underlying model or view model) as simple possible (ideally simply entity) because model isn't place logic (even if can relaxed underlying model because in domain objects logic , info tied together).

moreover list items may added/removed according many factors , span logic across controllers , model.

imagine have next requirement: "design view user can pick film list, list populated using past history pick best candidates; provide dropdown filter movies category". there lot of logic here, search in history, kind of smart algorithm pick best candidates , function prepare list. of course of study if there isn't drama film wouldn't set item in list. if set something in model you'll have set everything there, leaving controller stupid entity simply create model instance , pick right view. little, because controller methods easy reused between views model classes pretty more specific.

moreover here move list out of model. maintain model focused on real objects, user see , selects (so, if need it, don't worry json serialize them). if have model classes logic , others without (because they're json results, example) you'll find search logic both in model , controller. pretty confusing. available options (like film categories in previous example) view specific details maintain in viewbag.

is okay parametrize view adding view model controller , action names?

yes it's ok per se should inquire if it's not improve extract partialview, they'll embedded in outer view , it'll automatic; assuming have typical pattern:

actionresult edit() { } [httppost] edit(model data) { }

...view models storing data... there pattern logic out of controller?

i can't give here decent reply because depends on case. if view logic complex may need introduce lean layer encapsulate these stuff (controller interact them , set things won't aware of logic specific details).

storing info (model <-> view model) somehow easier, (often? always?) oom automapper solve of problems (without issues have orms). mapping done convention , if follow won't need write more few lines of code (and complicated cases can configured).

i know how write chrome extension, i've injected scripts , figured out how communicate pages, have basic knowledge of how tabs work , how build manifest.

what events looking , how can create work both , post requests?

use chrome.webnavigation.onerroroccurred or chrome.webrequest.onerroroccurred observe navigation errors. these apis cannot used in content script, have add together background page or event page extension.

i recommend utilize webnavigation api because these can used event pages (unlike webrequest api). here example, utilize chrome.tabs.reload instead of chrome.tabs.update want.

python - How to load previously saved model and expand the model with new training data using scikit-learn -

i'm using scikit-learn i've saved logistic regression model unigrams features training set 1. possible load model , expand new info instances sec training set (training set 2)? if yes, how can done? reason doing because i'm using 2 different approaches each of training sets (the first approach involves feature corruption/regularization, , sec approach involves self-training).

i've added simple illustration code clarity:

from sklearn.linear_model import logisticregression log sklearn.feature_extraction.text import countvectorizer cv import pickle traintext1 # training set 1 text instances trainlabel1 # training set 1 labels traintext2 # training set 2 text instances trainlabel2 # training set 2 labels clf = log() # count vectorizer used logistic regression classifier vec = cv() # fit count vectorizer training text info training set 1 vec.fit(traintext1) # transforms text vectors training set1 train1text1 = vec.transform(traintext1) # fitting training set1 linear logistic regression classifier clf.fit(traintext1,trainlabel1) # saving logistic regression model training set 1 modelfilesave = open('modelfromtrainingset1', 'wb') pickle.dump(clf, modelfilesave) modelfilesave.close() # loading logistic regression model training set 1 modelfileload = open('modelfromtrainingset1', 'rb') clf = pickle.load(modelfileload) # i'm unsure how go on here....

logisticregression uses internally liblinear solver not back upwards incremental fitting. instead utilize sgdclassifier(loss='log') partial_fit method used although in practice. other hyperparameters different. careful grid search optimal value carefully. read sgdclassifier documentation meaning of hyperparameters.

countvectorizer not back upwards incremental fitting. have reuse vectorizer fitted on train set #1 transform #2. means token set #2 not seen in #1 ignored though. might not expect.

to mitigate can utilize hashingvectorizer stateless @ cost of not knowing features mean. read the documentation more details.

a yes both questions allow script move said file folder. here's have far:

for reason though i'm receiving error on line 9 files not beingness found. i'd added msgbox(objfile) , know much works enough, missing here?

angularjs - bind attribute to object property in isolated scope -

i have directive (using isolated scope) makes utilize of directive changes flag hence had set container object. now, want able set flag outside. allow me "draw" you:

outerscope (outerflag1 = true, outerflag2 = true) directivescope (container.flag1 = false, container.flag2 = false) subdirectivescope (container.flag1 = false) subdirectivescope (container.flag2 = false)

the flag variables in directivescope , subdirectivescope same, because container prototypically inherited. want able set outside, synchronize outerflagx container.flagx.

with isolated scope definition can map property so:

scope: { outerflag1: '=flag1' outerflag2: '=flag2' }

however, need not allowed is

scope: { outerflag1: '=container.flag1' outerflag2: '=container.flag2' }

how can done?

i added plunker based on 1 mikko provided (thanks lot): http://plnkr.co/edit/ht6zip

it have been great see real-life utilize case, in form of plunker/fiddle. problem might go away not defining isolated scope in subdirective.

given have next controller , 2 directives

// controller app.controller('mainctrl', function ($scope) { $scope.model = null; }); // top level directive app.directive('onedirective', function () { homecoming { restrict: 'e', scope: { flag: '=' }, template: '<label for="one">one directive</label><br>' + '<input type="text" name="one" ng-model="flag">' + '<br>' + '<other-directive></other-directive>' }; }); // nested directive app.directive('otherdirective', function () { homecoming { restrict: 'e', template: '<label for="other">other directive</label><br>' + '<input type="text" name="other" ng-model="flag">' }; });

java - Is it bad to import unused packages? -

java - Is it bad to import unused packages? -

for instance when work in team @ same file , have partial understanding of different packages imported needed code work. alter code in file , find out code become redundant because of that. delete part , not know if whole code still depends on packages or not.

[of course of study bad can objectified in many ways: speed, read-abilty etc.]

you should utilize few of imports necessary, , don't utilize finish bundle imports java.util.*. today's ide's back upwards "organize imports" operation during unused imports removed.

if have bunch of unused imports , modify code, there chance add/change code refers classes covered unused imports. won't notice accidentally utilized them though might not intent.

if have minimum imports, if add together code refers new class, compiler notify showing errors, , giving possibility take class intend use.

also if utilize imports beyond referenced in program, increment chance break programme future releases of java or libraries use.

example: if programme uses java.util.hashset still import java.util.* , utilize 3rd party library import com.mylib.*, code might compile. if in future release 3rd party library adds class named com.mylib.hashset, you're code might not compile anymore because compiler might not able tell class wanted utilize (e.g. java.util.hashset or com.mylib.hashset). have imported java.util.hashset , e.g. com.mylib.someutil in first place, code still compile new version of 3rd party lib.

in picturebox1 paint event tried draw rectangle around image in picturebox1:

private void picturebox1_paint(object sender, painteventargs e) { e.graphics.drawrectangle(new pen(brushes.red, 5), new rectangle(0, 0, picturebox1.image.width, picturebox1.image.height)); }

but this:

and tried draw rectangle aorund picturebox1 self:

private void picturebox1_paint(object sender, painteventargs e) { e.graphics.drawrectangle(pens.green, 0, 0 , picturebox1.width, picturebox1.height); }

but in case i'm getting thick greenish line on left , top right , bottom without green.

the picturebox1 in desinger it's property sizemode set stretchimage how can draw rectangles in both cases ?

and how property of top line called ? it's not height maybe top ? if want find , draw on top of picturebox how called ?

to draw within picturebox easy:

private void picturebox1_paint(object sender, painteventargs e) { float penwidth = 5f; pen mypen = new pen (brushes.red, (int)penwidth); e.graphics.drawrectangle(mypen, penwidth / 2f, penwidth / 2f, (float)picturebox1.width - 2f * penwidth, (float)picturebox1.height - 2f * penwidth); mypen.dispose(); }

to draw outside picturebox need know command underneath it. eg if form utilize form paint:

private void form1_paint(object sender, painteventargs e) { int linewidth = 5; brush mybrush = new solidbrush (color.green); e.graphics.fillrectangle(mybrush, picturebox1.location.x - linewidth, picturebox1.location.y - linewidth, picturebox1.width + 2 * linewidth, picturebox1.height + 2 * linewidth); mybrush.dispose(); }

i using fillrectangle because part under picturebox not visible , easier command width.

sql server - Error in creating tables in SQL -

i'm trying create few tables in new database, when seek create them creates couple of errors. i'm using microsoft sql server management studio.

the errors seem in end of code i'm trying add together constraints foreign keys. help appreciated give thanks you.

here's code, it's meant generate 3 tables 1 table containing 2 foreign keys other tables matching column names.

create table customers ( customerid int not null primary key identity, contactname varchar(50) null, company varchar(45) null, phone varchar(12) null, ) create table shippers ( shipperid int not null primary key identity, company varchar(45) null, phone varchar(12) null, ) create table orders ( orderid int not null primary key identity, orderdate datetime null, shippeddate datetime null, shipperid int null, freight decimal null, customerid int null, constraint fk_orders_shippers foreign key shipperid references shippers(shipperid) on delete no action on update no action constraint fk_orders_customers foreign key customerid references customers(customerid) on delete no action on update no action )

and these errors get:

msg 102, level 15, state 1, line 21 wrong syntax near 'shipperid'.

msg 102, level 15, state 1, line 23 wrong syntax near 'action'.

msg 102, level 15, state 1, line 28 wrong syntax near 'action'.

any ideas problem is?

the error messages point couple of surplus commas, missing comma , improper foreign key syntax due missing parentheses.

this right version:

create table customers ( customerid int not null primary key identity, contactname varchar(50) null, company varchar(45) null, phone varchar(12) null -- surplus comma removed ) create table shippers ( shipperid int not null primary key identity, company varchar(45) null, phone varchar(12) null -- surplus comma removed ) create table orders ( orderid int not null primary key identity, orderdate datetime null, shippeddate datetime null, shipperid int null, freight decimal null, customerid int null, constraint fk_orders_shippers foreign key (shipperid) -- parentheses added references shippers(shipperid) on delete no action on update no action , -- comma added constraint fk_orders_customers foreign key (customerid) -- parentheses added references customers(customerid) on delete no action on update no action )

regex - Ruby Reg Ex Identify Pipe Within Quotes -

i want regex identify pipe characters within double quotes.

i using

\".+\|.+\"

which correctly matches on '1|some "quote | text"|4' , correctly not match on '1|some "quoted" text|4'

however, matches on '1|some "quoted" text|4|5|6|more "quoted" text|9' because there 2 sets of quotes - sees outer-most quotes , pipes between.

how alter regex not match in case?

update: turns out need match on multiple pipes within quotes. had been using:

/\"([^|]+)\|([^|]+)\"/

which works 1 pipe within quotes, such "1|some "quote | text"|4", need match on "1|some "quote | text | | pipes"|4".

any ideas???

instead of using .+ matches character, want match character except |. want [^|]+. based on have written, should want.

c++ - Using NtAllocateVirtualMemory() via GetProcAddress will not compile -

i'm trying utilize ntallocatevirtualmemory project , i'm sure others have had success w/it, not compile on vsc++ 2010 nor mingw. on both compilers says

farproc: many arguments call

does know how can code compile? time.

farproc ntallocatevirtualmemory; ntallocatevirtualmemory = getprocaddress(getmodulehandle("ntdll.dll"), "ntallocatevirtualmemory"); printf( "ntallocatevirtualmemory %08x\n", ntallocatevirtualmemory); returncode = ntallocatevirtualmemory(getcurrentprocess(), &baseaddress, 0, &regionsize, mem_commit | mem_reserve, page_execute_readwrite);

you need cast result getprocaddress function pointer of right type. in case:

typedef ntstatus winapi (*pntallocatevirtualmemory)(handle processhandle, pvoid *baseaddress, ulong_ptr zerobits, psize_t regionsize, ulong allocationtype, ulong protect); farproc navm = getprocaddress(...); pntallocatevirtualmemory ntallocatevirtualmemory = (pntallocatevirtualmemory)navm; ...

of course, much easier utilize virtualalloc.

virtualalloc(&baseaddress, regionsize, mem_commit | mem_reserve, page_execute_readwrite);

c++ winapi
