Javascript: print html as plain text : <p>I'm trying to print plain html from javascript and can't figured out how to do so.
Example:</p>
<pre><code>$('#elem').html('This is a normal string'); // --> This is a normal string
$('#elem').html('This <b>contains</b> html')
//Current-> This contains html (contains is bold)
//Wanted-> This <b>contains</b> html
</code></pre>
<p>I want to do this because I'm working with comments written by users and don't want html tags to apply if they put some in their comments. But for other reasons I need to see the tags.</p>
<p>Thanks for your help!</p>

Use regex backreference inside character except class [^] : <p>Lets take:</p>
<p><code>stringi = 'xnxx xnnx xnnxn'</code></p>
<p>My regex is: <code>(n)[^n]</code></p>
<p>I want to make my regex a little more dynamic like that:</p>
<p><code>(n)[^\1]</code> -<code>\1</code> beeing the capt. grp 1</p>
<p>My desired result would be that:</p>
<ul>
<li><code>(n)[^\1]</code> would be equal <code>(n)[^n]</code></li>
<li><code>(x)[^\1]</code> would be equal <code>(x)[^x]</code></li>
</ul>
<p>How can I not match a <code>NOT-\1</code> character?</p>

Else if statement executing unexpectedly, behaving as else statement : <p>I'm working on a simple function to convert ascii codes to array indexes, and I'm have a bit of trouble with the else-if statement. </p>
<pre><code>int getIndex(char character) {
int code = int(character);
int index = -1;
if (code == int(' ')){
index = 26;
} else if (int('a') <= code <= int('z')) {
index = code - int('a');
}
return index;
}
</code></pre>
<p>The if condition works fine and fires on spaces, but the else if statement fires in every other case, regardless of whether the character is in the range a to z or not. Is there a problem I can't see with the condition? </p>

Coding unity shaders with unity visual studio : <p>Recently I've been coding shaders for unity in visual studio and I've noticed that since unity shaders are written in a combination of unity's shader lab language and CG, visual studio 2015 doesn't seem to recognize the languages. Because of this, visual studio is not reconizing keywords, has no intellesense, and worse of all tabbing incorrectly whenever I press enter to go to a new line. I've tried this visual studio extension <a href="https://visualstudiogallery.msdn.microsoft.com/ed812631-a7d3-4ca3-9f84-7efb240c7bb5" rel="noreferrer">https://visualstudiogallery.msdn.microsoft.com/ed812631-a7d3-4ca3-9f84-7efb240c7bb5</a> and it doesn't seem to fully work. I was wondering if anyone on here has had experience working with shaders and has an extension they know about to fix this problem.</p>

How do I map OAuth 2 token to UserDetails object in a resource server? : <p>I have 2 separate Spring Boot applications, one serving as an an OAuth 2 authorization server, and the other as resource server. I'm using Spring's <code>RemoteTokenServices</code> in my resource server to check tokens from the authorization server. Now, I'm trying to define protected controller code in my resource server application, but I'm not sure how to map the <code>UserDetails</code> class to the authentication principal provided through the OAuth 2 mechanism. </p>
<p>I have set up my authorization server with a custom <code>TokenEnhancer</code> that adds more details to the token such that <code>/oauth/check_token?token=<token></code> returns with custom fields, which I want to map to my resource server controllers.</p>
<p>In a more monolithic setup where the authorization server is also the resource server, I can define controller methods that make use of the authenticated principal this way:</p>
<pre><code>//User implements UserDetails
public Map<String, Object> getResource(@AuthenticationPrincipal User user) {
//code that uses the user object
}
</code></pre>
<p>However, this doesn't seem to work as straight forward in a more distributed approach. The mapping fails, and the <code>user</code> parameter ends up being a null object. I tried using the following approach:</p>
<pre><code>public Map<String, Object> getResource(Authentication authentication) {
//code that uses the authentication object
}
</code></pre>
<p>While the code above successfully maps the authentication details, it doesn't provide a way for me to directly access the custom fields I've set through the <code>TokenEnhancer</code> I mentioned earlier. I can't seem to find anything from the Spring docs regarding this.</p>

Launch an event when checking a checkbox in Angular2 : <p>I'm newbie in Angular2 and in web globally , I want to launch an action that changes an oject paramater value in the Database when checking a <code>checkbox</code> and or unchecking it using <code>Material-Design</code>, I tried with <code>[(ngModel)]</code> but nothing happened. the idea is that i have to add some propositions with <code>checked | unchecked</code> status to tell if it is a <code>true</code> or <code>false</code> proposition. Here is the proposition model </p>
<pre><code> export class PropositionModel {
id:string;
wordingP:string; // the proposition
propStatus:Boolean; // the proposition status
}
</code></pre>
<p>here is the Html code for a proposition :</p>
<pre><code><div class="uk-width-xlarge-1-1 uk-width-medium-1-2">
<div (submit)="addProp1()" class="uk-input-group">
<span class="uk-input-group-addon"><input type="checkbox" data-md-icheck/></span>
<label>Proposition 1</label>
<input [(ngModel)]="proposition1.wordingP" type="text" class="md-input" required class="md-input"/>
</div>
</div>
</code></pre>
<p>here is the TypeScript code for adding the proposition:</p>
<pre><code>addProp1() {
this.proposition1 = new PropositionModel();
this.proposition1.propStatus = false;
this.propositionService.addProposition(this.proposition1)
.subscribe(response=> {
console.log(response);
console.log(this.proposition1);
this.proposition1 = new PropositionModel();})
}
</code></pre>
<p>And as you can see i made it a <code>false</code> by default for the <code>proposition status</code> and I want to change it once i checked the proposition.
Here is an image how it looks for a better issue understanding.

Angular 4 Property does not exist on type Object on build : <p>I'm building a project using Angular, I started the project using angular-cli and when I try to run <code>ng build --prod</code> i keep getting this error:</p>
<blockquote>
<p>Property 'description' does not exist on type Object</p>
</blockquote>
<p>The code generating this error is the following:</p>
<pre><code>export class AppComponent {
product: Object = {};
constructor(
private store: StoreService,
private request: RequestService,
) {
this.product = this.request.getProduct(_id);
}
}
<p>{{product.description}}</p>
</code></pre>
<p>I was reading some content about this and the error is because I'm using type definition to define product as Object, but I'm not passing any property definition.</p>
<p>I know I could define an Interface, like I do with arrays, but I wasn't able to do it. I don't know if I'm defining it wrong, this is how I tried:</p>
<pre><code>export interface ProductInterface {
id: Number;
description: String;
title: String;
}
product: Object<ProductInterface> = {};
</code></pre>
<p>But it also gives me errors. What do I need to do to avoid this?</p>

<li>App Service 3 (app service plan 1)</li>

<p>I would like to move <code>App Service 3</code> which is into <code>Resource group 2</code> but uses <code>app service plan 1</code>, to <code>app service plan 2</code>.</p>
<p>Is this possible? I have tried to use the feature "Change App service plan" available on the new portal but when I click on it a blade appear saying that "No App Service plan found".</p>
<p>I suspect that the blade looks for app service plan available on the original resource group and does not permit neither to create a new one.</p>
<p>Please see the attached picture for details.</p>

Download Blob file from Website inside Android WebViewClient : <p>I have an HTML Web page with a button that triggers a POST request when the user clicks on. When the request is done, the following code is fired:</p>
<pre><code>window.open(fileUrl);
</code></pre>
<p>Everything works great in the browser, but when implement that inside of a Webview Component, the new tab doesn't is opened.</p>
<p>FYI: On my Android App, I have set the followings things:</p>
<pre><code>webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setSupportMultipleWindows(true);
webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
</code></pre>
<p>On the <code>AndroidManifest.xml</code> I have the following permissions:</p>
<pre><code><uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_DOWNLOAD_MANAGER"/>
</code></pre>
<p>I try too with a <code>setDownloadListener</code> to catch the download. Another approach was replaced the <code>WebViewClient()</code> for <code>WebChromeClient()</code> but the behavior was the same.</p>

Infinite loop and CPU usage on single core and multicore : <p>Interviewer has asked me this question and I want to understand concept ie how CPU usages varies :</p>
<p>1) If infinite loop is running in single-threaded design with single core machine </p>
<p>2) If infinite loop is running in single-threaded design with multi-core machine ( 4 core )</p>
<p>3) If infinite loop is running in multi-threaded design with single core machine </p>
<p>4)If infinite loop is running in multi-threaded design with multi-core machine (4 core )</p>
<p>5) What will happen when application is having more threads then hardware core. For ex : Application is creating 30 threads in 4 core machine. Will it increase the performance of application or decrease the performance ?</p>
<p>6) What will happen when application is having less threads then hardware core. For ex : Application is creating 5 threads in 4 core machine. Will it increase the performance of application or decrease the performance ?</p>
<p>Requesting you to explain the concepts so that things are clear. I have lot of confusion. </p>

Decoding Kubernetes secret : <p>I inherited a Kubernetes/Docker setup, and I accidentally crashed the pod by changing something relating to the DB password.</p>
<p>I am trying to troubleshoot this.</p>
<p>I don't have much Kubernetes or Docker experience, so I'm still learning how to do things.</p>
<p>The value is contained inside the db-user-pass credential I believe, which is an Opaque type secret.</p>
<p>I'm describing it:</p>
<pre><code>kubectl describe secrets/db-user-pass
Name: db-user-pass
Namespace: default
Labels: <none>
Annotations: <none>
Type: Opaque
Data
====
password: 16 bytes
username: 13 bytes
</code></pre>
<p>but I have no clue how to get any data from this secret. The example on the Kubernetes site seems to assume I'll have a base64 encoded string, but I can't even seem to get that. How do I get the value for this?</p>

$articulos = $em->getRepository("BDBundle:Articulos")->findAll();
$paginator = $this->get('knp_paginator');
$pagination = $paginator->paginate(
$articulos, $request->query->getInt('page', 1), 5);
return $this->render('AppBundle:Default:productos_listar.html.twig', array(
'pagination' => $pagination

How would it be the correct form? Thanks.

{
$string = preg_replace($pattern, "<a href='$1'>Name</a>", $string);

<p>I can get the results from the groups, and preserve the first part of the href. But if i try to change the name, it's the same for all results. </p>
<p>If I try to use "str_replace", I can have different results as intended, but this gave me 2 problems. One is that if i try to replace the name, i also change the href, and if i have similar URL with "more slashes" it will change the match part, and leave the rest of the information.</p>
<p>In a database I have list of URL with a column that have names, and if the string match any row in the table I need to change the name accordingly and preserve the href. </p>

How to write a CSV file without using external libraries : <p>I have already checked out these libraries <code>oledb</code>, <code>Microsoft Text Writer</code>, and <code>TextFieldParser</code>. We are not allowed to use oledb and Microsoft Text Driver on the server. Also, not allowed to use external libraries. I see that TextFieldParser only reads the file. Is there a way to write a CSV file natively in C#? I am aware that write a CSV is pretty complex so I don't want to roll my own solution. </p>

Regex to be made which should include international and cyrilic characters : The regex should fullfill the below conditions:
- Minimum of 3 characters (includes alphabets and numbers, not
including Special Characters
)
- It Must have at least 3 compulsory alpha-numeric characters excluding
special characters
- All alphabets cannot be the same in a standalone word. However, if
they are a part of the word, we will allow the same. For example -
AAA is not allowed but Haaadoop is allowed
- Consecutive alphabets less than or equal to 3 are allowed in a word.
Ex– Haaadoop is allowed but Haaaadoop is not allowed.
- Three or more consecutive Standalone alphabets are not allowed.
Example - AA is allowed. AAA is not allowed.
- All numbers can be the same. Example – 111 is allowed
- If more than 1 special character (In a word or Standalone) are
consecutively entered, it is invalid. Example A-B is allowed, A- -B
or A-&B is not allowed
- Allow special characters #&()_+[]:;',/.\\\-"*
- Consecutive dashes, apostrophes are not allowed in any part of the
string
- It should accept these international and cyrilic characters as well

How to create a list of random numbers? : <p>So I am trying to create a method in which random numbers between 1000 and -1000 are declared and stored in an arraylist. The issue is, I need to use a user inputted number to determine how many random numbers I need. Therefore, I assume I need some sort of loop which will create a random number(within the given boundaries) for the given amount of times the user desires. To make things clear, if the user inputted the number 10, than 10 random numbers would be created and stored in the arraylist.</p>
<p>For this example, the user inputted data is gathered from a jtextField called n2sInput.</p>
<p>If anyone could explain, or create a sample code of how to do this, I would greatly appreciate it!</p>
<p>Thanks</p>

Why is AppTheme.NoActionBar not working? : <p>I've created an Android app in Android Studio, and it has created these styles by default:</p>
<pre><code><style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
</code></pre>
<p>However, in an activity, I try to set this as a theme:</p>
<pre><code><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
...
android:theme="@style/AppTheme.NoActionBar">

<p><a href="https://i.stack.imgur.com/dVFTn.png" rel="noreferrer"><img src="https://i.stack.imgur.com/dVFTn.png" alt="enter image description here"></a></p>
<p>Why am I getting an action bar? Am I doing something obviously wrong, or is Android Studio, Google's official IDE for it's own platform, trying to confuse/mislead its developers?</p>
<p>Here is my activity code, there's nothing in it that can cause the action bar to appear by itself:</p>
<pre><code>public class WelcomeActivity extends AppCompatActivity {
@Override
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
super.onCreate(savedInstanceState, persistentState);
setContentView(R.layout.activity_welcome);

javascript 2 elements in different variables, how to combine them? : <p>I have to variables, containing 2 different elements. I want to combine them into a single jquery selector. At the moment I have something like this:</p>
<pre><code>function getActiveElem(){
return $('div').find('.active');
}
var elem1 = $('.elem1'),
elem2 = getActiveElem();
</code></pre>
<p>I can't do it like this:
<code>$('div .active, .elem1')</code> because the <code>getActiveElem</code> is a little more complex than the example.
What I would like to do is this: <code>$(elem1, elem2)</code> to get both elements, but that isn't working.</p>
<p>Ultimately I want to animate these 2 items at the same time. Right now it's like this:</p>
<pre><code>elem1.animate({});
elem2.animate({});
</code></pre>
<p>And I'd like it to be </p>
<pre><code>$(elem1, elem2).animate({});
</code></pre>
<p>Is this possible? Does it even make sense? I'm animating a custom slider but there's some weird whitespace between the slides, I thought it might be because of the 2 seperate slide events.</p>

Hey Folks Need Some Assistance : I'm hoping someone could show me the right direction to go with this. I'm working on a javascript project for a restaurant website. What i'm supposed to do is, show different lunch/dinner/happy hour specials at different times throughout the day( dynamic). I'm thinking arrays with the specials. and something like a getDay() or getTime() method to show a certain special, but i'm not sure 100% about how to approach this. Any help would be greatly appreciated. Also, my code needs to be strictly javascript/html. no jquery or json or anything else. Thank you! | 0debug |

Why Form freezes when using BackgroundWorker in C#? : I am new to C# and I am using windows forms
I have a problem with doing some work in BackgroundWorker.
I have 2 forms (`Form1` and `Form2`) and 3 `User Controls` `UC1`, `UC2` and `UC3`.
`Form1` has only one `button` which shows `Form2` which you click on it.
`Form2` has 4 `buttons` (`Btn_ShowUC1`, `Btn_ShowUC2`, `Btn_ShowUC3` and `Button_Close`) and 3 `BackgroundWorkers`.
What I am trying to do is: when I click on `button1` in `Form1`, `Form2` show up and then I want to show the relevant `User control` and hide the rest when I click on any button in `Form2`. For example: click on `Btn_ShowUC1` `user control1` shows up and hide the rest, click on `Btn_ShowUC2` `user control2` shows up and hide the rest and so on. Now showing and hiding the `user controls` in UI sometimes cuases `Form2` to freeze therefore I used BackgroundWorkers to Show/Hide `user control` process.
I am using 3 `BackgroundWorkers` for each relavant button in case one `BackgroundWorker` is busy to do the show/hide processs.
In Form1:
Form2 f2 = new Form2();
private void button1_Click(object sender, EventArgs e)
{
f2.ShowDialog();
}
In Form2:
UserControl CurrentUserControl;
UserControl1 uc1 = new UserControl1();
UserControl2 uc2 = new UserControl2();
UserControl3 uc3 = new UserControl3();
public Form2()
{
InitializeComponent();
Controls.Add(uc1);
Controls.Add(uc2);
Controls.Add(uc3);
}
private void Form2_Load(object sender, EventArgs e)
{
foreach (Control ctrl in this.Controls)
{
if (ctrl is UserControl)
{
ctrl.Visible = false;
}
}
uc1.Visible = true;
}
private void Btn_ShowUC1_Click(object sender, EventArgs e)
{
CurrentUserControl = uc1;
backgroundWorker1.RunWorkerAsync();
}
private void Btn_ShowUC2_Click(object sender, EventArgs e)
{
CurrentUserControl = uc2;

When `Form2` loads `usercontrol1` shows up and when I click any any button the relevant user control shows up and every thing works well. However, When I close `form2` and open it again and click on any button none of the `user controls` show up and `Form2` freezes and it throws error saying "This backGroundWorker is currently busy and can not run multiple tasks concurrently"
Why I am having this error? I mean I am using 3 different `backGroundWorkers`.
Note this is all the code I have in the project.
Anyone knows how can I fix it? I mean I want to show/hide the user controls in separate thread when I click on any button without freezing the form.
I will be very happy to hear any different ideas.
Thank you | 0debug |

Inherit from const type passed as template parameter : <p>The following code is not valid:</p>
<pre><code>struct base {
};
struct inherit : const base {
};
</code></pre>
<p>You cannot inherit from a <code>const</code> type.</p>
<p>Does the situation change when templates are involved? In other words, is this code valid:</p>
<pre><code>struct base {
};
template<typename T>
struct inherit : T {
using T::T;
};
int main() {
inherit<base const>{};
}
</code></pre>
<p>gcc is says it is fine, but clang reports </p>
<pre><code><source>:6:2: error: 'const base' is not a direct base of 'inherit<const base>', cannot inherit constructors
using T::T;
^ ~
<source>:10:2: note: in instantiation of template class 'inherit<const base>' requested here
inherit<base const>{};
^
1 error generated.
Compiler returned: 1
</code></pre>
<p>To make clang happy, I need to do something like this:</p>
<pre><code>template<typename T>
struct inherit : T {
using U = std::remove_const_t<T>;
using U::U;
};
</code></pre>
<p>Which version is correct? Or are neither of them correct and I need to inherit from <code>std::remove_const_t<T></code>?</p>

creation of a structure of cells : I have a set of data as can be seen from the attached snapshot. As can be observed, it is a set of repetitive data. I am trying to write a code such that the code would create a main structure "RoadXML" with all the subsequent text in the cell as structure elements.
For eg: " RoadXML.Network.SubNetworks.SubNetwork.RoadNetwork.Grounds.Ground" should produce a structure RoadXML which has a struct element "Networks" which inturn is a structure. Likewise " Networks" should have " Subnetworks" as an element which is a structure and so on... Furthurmore, the rest of the data should append itself to the main structure under its respective fields. Hence in the end only one structure would remain with all the data in the excel sheet as its structure elements.
Now the problem is that, when repetitive sets of elements are present in the excel sheet as can be seen from the screenshot, only the last set of data remains thus overwriting the data that has been already stored. That is to say (with reference to the attached screenshot) data from rows 30 to 34 over writes all the data from rows 15 to 29 that has been alreaady stored.
Requesting assistance for getting over this issue that i have.
Thanks in advance,

Why does VBA exist? : I have this function (which I based off a function [here][1]):
Function Foo(ByVal r As range) As String
MsgBox "WHAT. The function worked? Wow!"
End Function
I have tried calling it like so:
Let max_row = cells.CurrentRegion.Columns.Count
Set r = range(cells(2, ID_COL), cells(max_row, ID_COL))
Foo r
And I Always Get the Error: "run-time error 13, type mismatch" once the code hits the call to Foo.
Additionally, putting parentheses around the "r"
Foo(r)
Auto corrects to:
Foo (r)
Which gives the error: "Object Expected"
I assume this means that parentheses deference a pointer to its value, and are not meant for function calls, because VBA was not designed to be a good or even adequate language.
I have also tried writing the function as:
Function Foo(r As range) As String
MsgBox "WHAT. The function worked? Wow!"
End Function
But with no success.
Any ideas?

What is: A curly brace enclosure with a first variable name then a colon which separates the same variable name again? {name:name} : <p>This possibly relates to Javascript, TypeScript, or Angular 2. I'm not sure?</p>
<p>Here is an example:</p>
<pre><code>onSearch( term:string)
{
this.router.navigate([' search', {term: term}]);
}
</code></pre>
<p>I don't understand what the '{term: term}' is doing?</p>

How to specify ranges to java.util.Random? : <p>I don't know why Java's designers didn't design java.util.Random objects to return random numbers like this: </p>
<p><code>rand.nextInt(minValue, maxValue);</code></p>
<p>I don't understand how to pass min and max values to this function. I've seen this recommended:</p>
<p><code>random.nextInt(max + 1 - (min)) + min</code></p>
<p>but what does that mean? Does that mean: </p>
<p><code>random.nextInt(FULL_RANGE + 1) + START_OF_RANGE</code></p>
<p>For example, if I wanted to generate values between -1 and 1, inclusive, is this how I do it:</p>
<p><code>int oneOfThreeChoices = rand.nextInt(1 + 1 + 1) - 1;</code></p>

Number generated randomly ? and problem here with the 2nd if statement? : <p>it is show that error in the 2nd If statement why???</p>
<pre><code>import java.security.SecureRandom;
public class Test
{
public static void main(String[] args)
{
System.out.println("T : " + Tfun());
}
public static String Tfun()
{
SecureRandom r = new SecureRandom();
int T = 1+r.nextInt(10);
if(T >= 1 && T <= 5)
Integer.toString(T);
return "Fast_Plod";
if(T >= 6 && T <= 7)
Integer.toString(T);
return "Slow_Plod";
}
}
</code></pre>
<p>how to fix that? what is the problem exactly?</p>
