Difficulty dynamically adding a border around a div using Javascript : <p>We have a "Terms and Conditions" checkbox, and when "Place Order" is clicked, among other things, I want to validate that Terms&Conditions is checked, and if not, add a thin red border around the surrounding div. I am unable to get the following to work though.</p>
<pre><code>if (!terms.checked) {
console.log(terms.parentNode.parentNode);
terms.parentNode.parentNode.style.border = '1px red';
//terms.parentNode.parentNode.style.borderWidth = '1px';
//terms.parentNode.parentNode.style.borderColor = 'red';
}
</code></pre>
<p>I know my Javascript is getting the correct node, as when I log it to console and then hover over it, it highlights the element. As you can see from the commented out lines I've tried adding <code>borderWidth</code> and <code>borderColor</code> individually, but also to no avail.</p>
<p>I've referred to both <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/border" rel="nofollow noreferrer">https://developer.mozilla.org/en-US/docs/Web/CSS/border</a> and <a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/style" rel="nofollow noreferrer">https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/style</a> and cannot figure out what I should be doing differently. I've also created the following fiddle to no avail: <a href="https://jsfiddle.net/LLdozham/" rel="nofollow noreferrer">https://jsfiddle.net/LLdozham/</a></p>

In Xamarin XAML, how do I set a Constraint on a RelativeLayout using a Style? : <p>I am struggling to work out the XAML syntax to apply constraints to a <code>RelativeLayout</code> using a <code>Style</code>.</p>
<p>The first piece of Xamarin XAML below shows a pair of nested <code>RelativeLayout</code> elements used to construct a simple layout (the inner element simply puts a margin around an area to which I can add other content). This version of the code builds and runs fine on iOS and Android.</p>
<pre><code><?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="App2.Page1">
<RelativeLayout BackgroundColor="Gray">
<RelativeLayout BackgroundColor="Maroon"
RelativeLayout.HeightConstraint="{ConstraintExpression Type=RelativeToParent,Property=Height,Factor=0.9,Constant=0}"
RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent,Property=Width,Factor=0.9,Constant=0}"
RelativeLayout.YConstraint="{ConstraintExpression Type=RelativeToParent,Property=Height,Factor=0.05,Constant=0}"
RelativeLayout.XConstraint="{ConstraintExpression Type=RelativeToParent,Property=Width,Factor=0.05,Constant=0}">
<BoxView Color="Yellow"
RelativeLayout.HeightConstraint="{ConstraintExpression Type=RelativeToParent,Property=Height,Factor=0.25,Constant=0}"
RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent,Property=Width,Factor=0.25,Constant=0}"
RelativeLayout.YConstraint="{ConstraintExpression Type=RelativeToParent,Property=Height,Factor=0.25,Constant=0}"
RelativeLayout.XConstraint="{ConstraintExpression Type=RelativeToParent,Property=Width,Factor=0.25,Constant=0}"/>
</RelativeLayout>
</RelativeLayout>
</ContentPage>
</code></pre>
<p>What I would like to do it use the same layout on multiple pages, so I want to put the <code>RelativeLayout</code> constraints into a <code>Style</code>. This second piece of code does not parse or run, but I hope it shows what I am trying to achieve. If I can get the right syntax for this, the idea is that the <code>Style</code> can then be moved out into a shared file, so I can easily re-use it across multiple instances of <code>ContentPage</code>.</p>
<pre><code><?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

How to serialize into Json C# DateTime value? : <p>I have an object <strong>model</strong> that contains <strong>DateTime</strong> property.
This object is being serialized into Json format by calling</p>

<p>as a result, I am getting this string </p>
<blockquote>
<p>"/Date(1474398517910)/"</p>

<p>instead of DateTime. That's because Json doesnt support DateTime format, instead it uses a string.</p>
<p><strong>Question - how to make this string to look like real date, something like</strong> </p>
<blockquote>

Error in bind_rows_(x, .id) : Argument 1 must have names using map_df in purrr : <p>I'm using the spotifyr package to scrape spotify audio features for every song of specific albums in my dataset. My issue is that my dataset consists of some artists that are not on spotify -- so they shouldn't be returning any values. </p>
<p>My issue is that when I get to an artist that is not on spotify, I get this error:</p>
<pre><code>Error in bind_rows_(x, .id) : Argument 1 must have names

<p>I've tried wrapping the function in tryCatch to get <code>NA</code> for each column of the problematic row, but it doesn't seem to work.</p>
<p>Here's an example of my code (FYI, you need to get API access from spotify's website to run the spotifyr code)</p>
<pre><code>library(readr)
library(spotifyr)
library(dplyr)
library(purrr)
Sys.setenv(SPOTIFY_CLIENT_ID = "xxx") #xxx will be from spotify's website
Sys.setenv(SPOTIFY_CLIENT_SECRET = "xxx")

artist <- c("Eminem", "Chris Stapleton", "Brockhampton", "Big Sean, Metro Boomin")
album <- c("Revival", "From A Room: Volume 2", "SATURATION III", "Double or Nothing")

JS Cannot read property "length" of undefined : <p>I'm trying to create an object using a given string where each word has a property stating its length. </p>

for (var i = 0; i <= str.length; i++){
strings[splitStr[i]] = splitStr[i].length;
}

}
findLongestWord("The quick brown fox jumped over the lazy dog");
</code></pre>
<p>I end up getting:</p>
<pre><code>"TypeError": Cannot read property "length" of undefined.
</code></pre>
<p>If I were to replace splitStr[i].length with splitStr[0].length, the code runs properly, but of course giving me the same number for each word in the object.</p>
<p>Any help is appreciated, thanks.</p>

Best practice for passing enum params in Web API : <p>I have a RESTful Web API project, and I have 2 different Enum scenarios that I'm unsure of re best practice.</p>
<p><strong>Scenario 1 : Straightforward Enum Param</strong></p>
<p>My API method requires a parameter called <code>ruleType</code>, with valid values being <code>EmailAddress</code> and <code>IPAddress</code>.
My enum within the Web API project looks like this:</p>
<pre><code>public enum RuleType
{
None = 0,
EmailAddress = 1,
IPAddress = 2
}
</code></pre>
<p>My question for this scenario is, should I use <code>?ruleType=EmailAddress</code> in my request to the API (which automatically binds that value to my <code>RuleType</code> property within the API method)? If so, how best to validate that the <code>RuleType</code> param sent, is a valid RuleType Enum value?</p>
<p><strong>Scenario 2 : Multiple Enum Values for a Single Param</strong></p>
<p>My API method has an optional <code>fields</code> param, which is allows you to specify any additional data that should be returned. E.g. <code>&fields=ruleOwner,rule</code>. This would return those 2 extra bits of data in the response.</p>
<p>I have an enum in the Web API project which relates to each possible <code>field</code> that may be requested, and at present, I am splitting the comma separated fields param, then looping through each string representation of that enum, parsing it to the equivalent enum, resulting in a list of Enum values which I can then use within my API to retrieve the relevant data.</p>
<p>This is the Enum:</p>
<pre><code>public enum OptionalField
{
None = 0,
RuleOwner = 1,
Rule = 2,
etc.
}
</code></pre>
<p>What would be best practice here? I was looking into bitwise enums, so a single value is sent in the API request which resulted in any combination of <code>fields</code> but didn't know if this would work well with a Web API, or if there's generally a better way to go about this?</p>

FormData append item in array : <pre><code> public List<Region> Regions { get; set; }

<p>in model called News.An Region Model is</p>
<pre><code>public class Region

public string Name { get; set; }
public static Region Parse(DataRow row)
{
return new Region
{
Id = Database.GetInteger(row["Id"]),
Name = Database.GetString(row["Region"]),
};
}
}
</code></pre>
<p>in Javascript I am using AJAX post method with formdata. I want to set this region.</p>
<pre><code>var regionList = [];
if (selected === "region") {
if (region.length <= 0) {
toastr.warning('Lütfen en az bir bölge seçin !!!');
return;
}
for (var i = 0; i < region.length; i++) {
var item = {
Id: region[i]
}
regionList.push(item);
}
console.log(regionList);
formData.append("Regions", regionList);
}
</code></pre>
<p>Code above in JS i wrote like this to set it</p>
<pre><code> public ActionResult AddByRegion(News item)
{
int refPortal = SessionRepository.GetPortalId();
if(refPortal!=1)
return View("List", NewsRepository.ListAll(SessionRepository.GetPortalId()));
if (item == null
|| string.IsNullOrEmpty(item.Title)
|| string.IsNullOrEmpty(item.Content)
)
return Content(Serialization.JsonSerialize(new { Status = 400 }));
return Content(Serialization.JsonSerialize(new { Status = 200, Result = NewsRepository.AddByRegion(item) }));
}
</code></pre>
<p>and code above i will get in controller. But it returns always 0 record although at least i choosed two region.</p>
<pre><code> $.ajax({
type: 'POST',
url: '@Url.Action("AddByRegion", "News")',
data: formData,
contentType: false,
processData: false,
success: function(data) {
var result = JSON.parse(data);
if (result.Result === "SUCCEED") {
toastr.success('@Resources.Resource.Success_MediaAdd');
window.location.reload();
return;
}
else {
toastr.error('@Resources.Resource.Error_Unexpected');
return;
}
},
error: function(error) {
toastr.error('@Resources.Resource.Error_Unexpected');
return;
},
beforeSend: function() {
waitingDialog.show('Wait...');
},
complete: function() {
waitingDialog.hide();
}
});
</code></pre>
<p>My Ajax method is above. Where am I making mistake ?</p>
<p>Thanks in advance.</p>

comparing two big lists(More than 1 Lack) in java : I want to compare two big string lists faster in java which are not of equal size.
I want to know is there any better way to improve performance.
I see performance issue in
List<String> list1 = 1 Lack records and
List<String> list2 = 100 lack records;
#method1 used removeAll
list1.removeAll(list2);
method2 used java8 streams
List<String> unavailable = list1.stream()
.filter(e -> (list2.stream()
.filter(d -> d.equals(e))
.count())<1)
.collect(Collectors.toList());

Looking for a light-weight cross-platform C threading library : <p>I wanted to use OpenMP for this, but it is not appropriate for my purposes: creating my own thread pool.</p>
<p>So, this needs to be C89 code with, of course, platform specific code for windows and unices.</p>
<p>I need this for a C only library, so no C++, boost C++11, etc.</p>
<p>Thanks!</p>

ASP/C#/SQL - Checkbox List - Store multiple values in database where checked : I have a checkboxlist.
<asp:CheckBoxList ID="cbBowelSounds" runat="server">
<asp:ListItem Text=" <span style=font-weight:normal;>1 Quadrant</span>" Value="1 Quadrant" />
<asp:ListItem Text=" <span style=font-weight:normal;>2 Quadrant</span>" Value="2 Quadrant" />
<asp:ListItem Text=" <span style=font-weight:normal;>Hypo</span>" Value="Hypo" />
<asp:ListItem Text=" <span style=font-weight:normal;>Hyper</span>" Value="Hyper" />
<asp:ListItem Text=" <span style=font-weight:normal;>Normal</span>" Value="Normal" />
</asp:CheckBoxList>
You can select multiple values. I want to store those values in a SQL database. At first I thought I would create 5 columns in the sql table and I would add each selected value to the correct column. That didnt work.
Then I found this snippet.
var s = cbBowelSounds.SelectedValue;
string[] values = s.Split(',');
foreach (ListItem item in cbBowelSounds.Items) item.Selected = values.Contains(item.Value);
That was great... until the database reported this for the answer. System.String[]
So, what can I do here? whether it's one column with multiple values or 5 columns where the first listitem writes to column 1, etc., It doesn't matter me. I just need the values selected to be sent to the DB.
Thank you

Is there a definitive *nix command line tool for inspecting protocol buffers? : <p>I'm looking for a command-line utility that will, at a minimum, render binary protobuf data in human-readable form. Filtering and selection options (along the lines of <code>cut</code> for text) would be nice, but the primary object is to make the data visible for debugging purposes.</p>
<p>If there is no definitive tool for the job, links to relevant packages are fine.</p>

How would you guys approach this? :)</p>

List-initialization of an array without temporaries - not working in GCC : <p>Consider the following contrived example</p>
<pre><code>struct A {
A(int) {}
A(const A&) = delete;
~A() {}
};
struct B {
A a[2] = {{1}, {2}};
};
int main() {
B b;
}
</code></pre>
<p>It compiles fine in <strong>clang</strong> (any version) but not in <strong>GCC</strong> (any version, any standard >= C++11)</p>
<pre><code><source>: In constructor 'constexpr B::B()':
<source>:7:8: error: use of deleted function 'A::A(const A&)'
struct B {
^
<source>:3:5: note: declared here
A(const A&) = delete;
^
<source>: In function 'int main()':
<source>:12:7: note: synthesized method 'constexpr B::B()' first required here
B b;
^
</code></pre>
<p><a href="https://gcc.godbolt.org/z/DneRbb" rel="noreferrer">LIVE DEMO</a></p>
<p>When A's destructor is commented out, it compiles fine also in GCC.</p>
<p><strong>Question is</strong> - who is right, clang or GCC, and why?</p>
<p>Initially I thought GCC is wrong, but then I saw <a href="https://timsong-cpp.github.io/cppwp/n3337/dcl.init.list#5" rel="noreferrer">[dcl.init.list]/5</a> which states that temporaries are created. Though I'm not sure if that applies here or if there's another rule that overrides this.</p>

How do I get the private key for a GoDaddy certificate so I can install it on Ubuntu 14+? : <p>The cert I have from StartSSL comes with a key file. But from GoDaddy, I get only the 2 .crt files. GoDaddy's instructions are for CentOS and explicitly do not work for Ubuntu.</p>
<p>How do I export the private key ... or get it from somewhere ... so I can use it with Apache SSL? The question that is ALMOST the same as mine assumes use of a Mac Keychain application. I don't run a Mac and I'm trying to do everything on the Ubuntu command line. I know there's a way to do this ... can anyone help me find it?</p>

Qeustion about the consumption of memory in OpenCV : Cross post [here](http://answers.opencv.org/question/178949/problem-about-the-consumption-of-memory/)
***
I have such simple code:
//OpenCV 3.3.1 project
#include<opencv.hpp>
#include<iostream>
using namespace std;
using namespace cv;
Mat removeBlackEdge(Mat img) {
if (img.channels() != 1)
cvtColor(img, img, COLOR_BGR2GRAY);
Mat bin, whiteEdge;
threshold(img, bin, 0, 255, THRESH_BINARY_INV + THRESH_OTSU);
rectangle(bin, Rect(0, 0, bin.cols, bin.rows), Scalar(255));
whiteEdge = bin.clone();
floodFill(bin, Point(0, 0), Scalar(0));
dilate(whiteEdge - bin, whiteEdge, Mat());
return whiteEdge + img;
}
int main() { //13.0M
Mat emptyImg = imread("test.png", 0); //14.7M
emptyImg = removeBlackEdge(emptyImg); //33.0M
waitKey();
return 0;
}
And this is my [test.png](http://answers.opencv.org/upfiles/15113815462075951.jpg). As the Windows show, it's size is about `1.14M`. Of course I know it will be larger when it is read in memory. But I fill cannot accept the huge consumption of memory.
If I use F10, I can know the `project.exe` take up `13.0M`. I have nothing to say about it
When I run `Mat emptyImg = imread("test.png", 0);`, the consumption of memory is `14.7M`. It is normal also.
But why when I run `emptyImg = removeBlackEdge(emptyImg);`, the consumption of memory is up to `33.0M`?? It mean function `removeBlackEdge` cost my extra `18.3M` memory. Can anybody tell me some thing? I cannot totally accept such huge consumption of memory. Is there I miss something? I use new `emptyImg` to replace the old `emptyImg`. I think I don't need extra memory to cost?
**Ps:** If I want implement to do same thing by my `removeBlackEdge`( delete that black edge in the image), how to adjust it to cost minimum consumption of memory?

Determine array type based on signature : Based on the signature, determine if the array is most likely perfect sized or oversized.
I know perfect sized arrays are used when the size of the array is known, otherwise an oversized array is used, but I don’t know how to determine the array type based on a signature.
For example: public static void myMethod(int[] ray, int size)
Or: public static myMethod(int[] ray, boolean value)

Get first and second element satisfying a CSS path : <p>Let's say I have a CSS path:
<code>.event__participant.event__participant--away</code>
How can I get the first element satisfying that path? Or second element? Or X element? I'm using selenium and I don't want to be getting all 100+ of them. <code>:nth-type-of</code> doesn't work and I can't use <code>nth-child</code> because it has more children than just <code>.event__participant--away</code>.</p>

Pointer offset causes overflow : <p>The following results don't make any sense to me. It looks like a negative offset is cast to unsigned before addition or subtraction are performed.</p>
<pre><code>double[] x = new double[1000];
int i = 1; // for the overflow it makes no difference if it is long, int or short
int j = -1;
unsafe
{
fixed (double* px = x)
{
double* opx = px+500; // = 0x33E64B8
//unchecked
//{
double* opx1 = opx+i; // = 0x33E64C0
double* opx2 = opx-i; // = 0x33E64B0
double* opx3 = opx+j; // = 0x33E64B0 if unchecked; throws overflow exception if checked
double* opx4 = opx-j; // = 0x33E64C0 if unchecked; throws overflow exception if checked
//}
}
}
</code></pre>
<p>Although it might seem strange to use negative offsets, there are use cases for it. In my case it was reflecting boundary conditions in a two-dimensional array.</p>
<p>Of course, the overflow doesn't hurt too much because I can either use unchecked or move the sign of the value to the operation by inverting and applying it to the modulus of the operand.</p>
<p>But this behaviour seems undocumented. According to <a href="https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/unsafe-code-pointers/arithmetic-operations-on-pointers" rel="noreferrer">MSDN</a> I don't expect negative offsets to be problematic:</p>
<blockquote>
<p>You can add a value n of type int, uint, long, or ulong to a pointer, p,of any type except void*. The result p+n is the pointer resulting from adding n * sizeof(p) to the address of p. Similarly, p-n is the pointer resulting from subtracting n * sizeof(p) from the address of p. </p>

Compile error when using std::cout between if/elseif statements : <p>I was wondering why I get a compile error when I try to use std::cout in between, say, an if statement and else if statement.
For example:</p>
<pre><code>if (condition)
{body}
std::cout << "hello world" << std::endl;
else if (condition)
{body}
</code></pre>
<p>Gives the error </p>
<pre><code>error: 'else' without a previous 'if'

[] = (), () = (), and {} = () 'assignments' : <p>I was surprised to find the following, in Python 3, the first two raise nothing:</p>
<pre><code>>>> [] = ()
>>> () = ()
>>> {} = ()
File "<stdin>", line 1
SyntaxError: can't assign to literal
</code></pre>
<p>In Python 2.7, only the first one raises nothing:</p>
<pre><code>>>> [] = ()
>>> () = ()
File "<stdin>", line 1
SyntaxError: can't assign to ()
>>> {} = ()
File "<stdin>", line 1
SyntaxError: can't assign to literal
</code></pre>
<p>What is going on here? Why are any of then not raising errors? And why was the <code>() = ()</code> presumably added to be valid in Python 3?</p>
<p>*Note, you can replace the right hand side with any empty iterable (e.g. <code>[] = set()</code>), I just choose an empty tuple for the illustration</p>

Use & to create a pointer to member : I'm trying to create a function that takes in a string, the reverses it, which is all being done in main. Here's what I have so far.
#include <cstring>
#include <iostream>
#include <string>
std::string str = "zombie";
void Reverse( std::string a)
{
char* a1 = a.c_str;
char* a2;
for (int i = (strlen(a1) -1); a1[i]!=0; i--)
{
a2 += a1[i];
}
str = a2;
}
int main()
{
Reverse(str);
std::cout << str << std::endl;
}
But i keep getting this error. I can't utilize pointers in this question. Any suggestions?

Spring WebFlux, how can I debug my WebClient POST exchange? : <p>I am having trouble understanding what I've done wrong in constructing my WebClient request. I would like to understand what the actual HTTP request looks like. (e.g., dumping the raw request to console)</p>
<pre><code>POST /rest/json/send HTTP/1.1
Host: emailapi.dynect.net
Cache-Control: no-cache
Postman-Token: 93e70432-2566-7627-6e08-e2bcf8d1ffcd

</code></pre>
<p>I am using Spring5's reactive tools to build an API. I have a utility class that will send an email using Dyn's email api. I would like to use The new WebClient class to accomplish this (<strong>org.springframework.web.reactive.function.client.WebClient</strong>)</p>
<p>The following command has been taken from : <a href="https://help.dyn.com/email-rest-methods-api/sending-api/#postsend" rel="noreferrer">https://help.dyn.com/email-rest-methods-api/sending-api/#postsend</a></p>
<pre><code>curl --request POST "https://emailapi.dynect.net/rest/json/send" --data "apikey=ABC123XYZ&from=example@example.com&to=customer1@domain.com&to=customer2@domain.com&to=customer3@domain.com&subject=New Sale Coming Friday&bodytext=You will love this sale."
</code></pre>
<p>When I make the call in curl with real values, the email sends correctly, so I feel like I am generating my request incorrectly.</p>
<p>My Send Command</p>
<pre><code>public Mono<String> send( DynEmailOptions options )
{
WebClient webClient = WebClient.create();
HttpHeaders headers = new HttpHeaders();
// this line causes unsupported content type exception :(
// headers.setContentType( MediaType.APPLICATION_FORM_URLENCODED );
Mono<String> result = webClient.post()
.uri( "https://emailapi.dynect.net/rest/json/send" )
.headers( headers )
.accept( MediaType.APPLICATION_JSON )
.body( BodyInserters.fromObject( options ) )
.exchange()
.flatMap( clientResponse -> clientResponse.bodyToMono( String.class ) );
return result;
