In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

I had to disable this in chrome://flags

You update core-js with the following command:

npm install --save core-js@^3

If you read the React Docs you will find that the command is derived from when you need to upgrade React itself.

you can declare your component like this:

const MyComponent: React.FunctionComponent = (props) => {
    return props.children;
}

I've faced the exactly same problem but I've fixed it with another approache.

Using Ubuntu 18.04, first disable systemd-resolved service.

sudo systemctl disable systemd-resolved.service

Stop the service

sudo systemctl stop systemd-resolved.service

Then, remove the link to /run/systemd/resolve/stub-resolv.conf in /etc/resolv.conf

sudo rm /etc/resolv.conf

Add a manually created resolv.conf in /etc/

sudo vim /etc/resolv.conf

Add your prefered DNS server there

nameserver 208.67.222.222

I've tested this with success.

npm update

It worked like a charm.

In my case I tried to run npm i [email protected] and got the error because the dev server was running in another terminal on vsc. Hit ctrl+c, y to stop it in that terminal, and then installation works.

For those that must keep compileSdkVersion 27 and are unable to upgrade to androidx yet, you must not upgrade to (or over) the versions of dependencies in the following links. These links are where the breaking change was introduced. You must find an earlier version that doesn't use androidx.

https://firebase.google.com/support/release-notes/android#update_-_june_17_2019

https://developers.google.com/android/guides/releases#june_17_2019

For instance, the following are compatible with compileSdkVersion 27:

dependencies {
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:support-v4:27.1.1'
    implementation 'com.google.android.gms:play-services-maps:16.1.0'
    implementation 'com.google.android.gms:play-services-location:16.0.0'
    implementation 'com.google.firebase:firebase-core:16.0.9'
    implementation 'com.google.firebase:firebase-messaging:18.0.0'
}

The following will break with compileSdkVersion 27 and are only compatible with compileSdkVersion 28:

dependencies {
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.google.android.gms:play-services-maps:17.0.0'
    implementation 'com.google.android.gms:play-services-location:17.0.0'
    implementation 'com.google.firebase:firebase-core:17.0.0'
    implementation 'com.google.firebase:firebase-messaging:19.0.0'
}

if browser can not find related css file, it could give this error.

If you use Angular application you do not have to put css file path on index.html

 <link href="xxx.css" rel="stylesheet"> -->

You could put related css file path on styles.css file.

@import "../node_modules/material-design-icons-iconfont/dist/material-design-icons.css";

Using the fontawesome-all.css file: Changing the "Brands" font-family from "Font Awesome 5 Free" to "Font Awesome 5 Brands" fixed the issues I was having.

I can't take all of the credit - I fixed my own local issue right before looking at the CDN version: https://use.fontawesome.com/releases/v5.0.6/css/all.css

They've got the issue sorted out on the CDN as well.

I used below code and it's working fine for me. :

let jsonText = "{\"userName\":\"Bhavsang\"}"
var dictonary:NSDictionary?
    
if let data = jsonText.dataUsingEncoding(NSUTF8StringEncoding) {
        
     do {
            dictonary =  try NSJSONSerialization.JSONObjectWithData(data, options: [.allowFragments]) as? [String:AnyObject]
        
            if let myDictionary = dictonary
              {
                  print(" User name is: \(myDictionary["userName"]!)")
              }
            } catch let error as NSError {
            
            print(error)
         }
}

To resolve this problem HttpClient is Angular's mechanism for communicating with a remote server over HTTP.

To make HttpClient available everywhere in the app,

1. open the root AppModule,

2. import the HttpClientModule from @angular/common/http,

   import { HttpClientModule } from '@angular/common/http';

3. add it to the @NgModule.imports array.

   imports:[HttpClientModule, ]

I made another variant with dropdown menu (perhaps for advanced search etc).. Here is how it looks like:

<div class="input-group my-4 col-6 mx-auto">
    <input class="form-control py-2 border-right-0 border" type="search" placeholder="Type something..." id="example-search-input">
    <span class="input-group-append">
        <button type="button" class="btn btn-outline-primary dropdown-toggle dropdown-toggle-split border border-left-0 border-right-0 rounded-0" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            <span class="sr-only">Toggle Dropdown</span>
        </button>
        <button class="btn btn-outline-primary rounded-right" type="button">
            <i class="fas fa-search"></i>
        </button>
        <div class="dropdown-menu dropdown-menu-right">
            <a class="dropdown-item" href="#">Action</a>
            <a class="dropdown-item" href="#">Another action</a>
            <a class="dropdown-item" href="#">Something else here</a>
            <div role="separator" class="dropdown-divider"></div>
            <a class="dropdown-item" href="#">Separated link</a>
        </div>
    </span>
</div>

Note: It appears green in the screenshot because my site main theme is green.

This is the minimum configuration that solves the problem.

use:

dependencies {
    ...
    implementation 'com.android.support:appcompat-v7:26.1.0'
    ...
}

with:

 compileSdkVersion 26
 buildToolsVersion "26.0.1"

and into the build.gradle file located inside the root of the proyect:

buildscript {
    ...
    ....
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        ...
        ...
    }
}

I'll share a code which has Basic Auth Header form data request body,

let username = 'test-name';
let password = 'EbQZB37gbS2yEsfs';
let formdata = new FormData();
let headers = new Headers();


formdata.append('grant_type','password');
formdata.append('username','testname');
formdata.append('password','qawsedrf');

headers.append('Authorization', 'Basic ' + base64.encode(username + ":" + password));
fetch('https://www.example.com/token.php', {
 method: 'POST',
 headers: headers,
 body: formdata
}).then((response) => response.json())
.then((responseJson) => {
 console.log(responseJson);

 this.setState({
    data: responseJson
 })
  })
   .catch((error) => {
 console.error(error);
   });

Your problem is that you are naming your component class Date. When you call new Date() within your class, it won't create an instance of the Date you expect it to create (which is likely this Date)- it will try to create an instance of your component class. Then the constructor will try to create another instance, and another instance, and another instance... Until you run out of stack space and get the error you're seeing.

If you want to use Date within your class, try naming your class something different such as Calendar or DateComponent.

The reason for this is how JavaScript deals with name scope: Whenever you create a new named entity, if there is already an entity with that name in scope, that name will stop referring to the previous entity and start referring to your new entity. So if you use the name Date within a class named Date, the name Date will refer to that class and not to any object named Date which existed before the class definition started.

I have recently written a blog about it for the Laravel5.6. Link to blog is https://www.samundra.com.np/integrating-font-awesome-with-laravel-5.x-using-webpack/1574

The steps are similar to above description. But in my case, I had to do extra steps like configuring the webfonts path to font-awesome in "public" directory. Setting the resource root in Laravel mix etc. You can find the details in the blog.

I am leaving the link here so it helps people for whom the mentioned solutions don't work.

We had this problem years ago before I had joined and had in place a solution that used local storage for user and environment information. Angular 1.0 days to be exact. We were formerly dynamically creating a js file at runtime that would then place the generated api urls into a global variable. We're a little more OOP driven these days and don't use local storage for anything.

I created a better solution for both determining environment and api url creation.

How does this differ?

The app will not load unless the config.json file is loaded. It uses factory functions to create a higher degree of SOC. I could encapsulate this into a service, but I never saw any reason when the only similarity between the different sections of the file are that they exist together in the file. Having a factory function allows me to pass the function directly into a module if it's capable of accepting a function. Last, I have an easier time setting up InjectionTokens when factory functions are available to utilize.

Downsides?

You're out of luck using this setup (and most of the other answers) if the module you want to configure doesn't allow a factory function to be passed into either forRoot() or forChild(), and there's no other way to configure the package by using a factory function.

Instructions

1. Using fetch to retrieve a json file, I store the object in window and raise a custom event. - remember to install whatwg-fetch and add it to your polyfills.ts for IE compatibility
2. Have an event listener listening for the custom event.
3. The event listener receives the event, retrieves the object from window to pass to an observable, and clears out what was stored in window.
4. Bootstrap Angular

-- This is where my solution starts to really differ --

5. Create a file exporting an interface whose structure represents your config.json -- it really helps with type consistency and the next section of code requires a type, and don't specify {} or any when you know you can specify something more concrete
6. Create the BehaviorSubject that you will pass the parsed json file into in step 3.
7. Use factory functions to reference the different sections of your config to maintain SOC
8. Create InjectionTokens for the providers needing the result of your factory functions

-- and/or --

9. Pass the factory functions directly into the modules capable of accepting a function in either its forRoot() or forChild() methods.

-- main.ts

I check window["environment"] is not populated before creating an event listener to allow the possiblilty of a solution where window["environment"] is populated by some other means before the code in main.ts ever executes.

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';
import { configurationSubject } from './app/utils/environment-resolver';

var configurationLoadedEvent = document.createEvent('Event');
configurationLoadedEvent.initEvent('config-set', true, true);
fetch("../../assets/config.json")
.then(result => { return result.json(); })
.then(data => {
  window["environment"] = data;
  document.dispatchEvent(configurationLoadedEvent);
}, error => window.location.reload());

/*
  angular-cli only loads the first thing it finds it needs a dependency under /app in main.ts when under local scope. 
  Make AppModule the first dependency it needs and the rest are done for ya. Event listeners are 
  ran at a higher level of scope bypassing the behavior of not loading AppModule when the 
  configurationSubject is referenced before calling platformBrowserDynamic().bootstrapModule(AppModule)

  example: this will not work because configurationSubject is the first dependency the compiler realizes that lives under 
  app and will ONLY load that dependency, making AppModule an empty object.

  if(window["environment"])
  {
    if (window["environment"].production) {
      enableProdMode();
    }
    configurationSubject.next(window["environment"]);
    platformBrowserDynamic().bootstrapModule(AppModule)
    .catch(err => console.log(err));
  }
*/
if(!window["environment"]) {
  document.addEventListener('config-set', function(e){
    if (window["environment"].production) {
      enableProdMode();
    }
    configurationSubject.next(window["environment"]);
    window["environment"] = undefined;
    platformBrowserDynamic().bootstrapModule(AppModule)
    .catch(err => console.log(err));
  });
}

--- environment-resolvers.ts

I assign a value to the BehaviorSubject using window["environment"] for redundancy. You could devise a solution where your config is preloaded already and window["environment"] is already populated by the time any of your Angular's app code is ran, including the code in main.ts

import { BehaviorSubject } from "rxjs";
import { IConfig } from "../config.interface";

const config = <IConfig>Object.assign({}, window["environment"]);
export const configurationSubject = new BehaviorSubject<IConfig>(config);
export function resolveEnvironment() {
  const env = configurationSubject.getValue().environment;
  let resolvedEnvironment = "";
  switch (env) {
 // case statements for determining whether this is dev, test, stage, or prod
  }
  return resolvedEnvironment;
}

export function resolveNgxLoggerConfig() {
  return configurationSubject.getValue().logging;
}

-- app.module.ts - Stripped down for easier understanding

Fun fact! Older versions of NGXLogger required you to pass in an object into LoggerModule.forRoot(). In fact, the LoggerModule still does! NGXLogger kindly exposes LoggerConfig which you can override allowing you to use a factory function for setup.

import { resolveEnvironment, resolveNgxLoggerConfig, resolveSomethingElse } from './environment-resolvers';
import { LoggerConfig } from 'ngx-logger';
@NgModule({
    modules: [
        SomeModule.forRoot(resolveSomethingElse)
    ],
    providers:[
        {
            provide: ENVIRONMENT,
            useFactory: resolveEnvironment
        },
        { 
            provide: LoggerConfig,
            useFactory: resolveNgxLoggerConfig
        }
    ]
})
export class AppModule

Addendum

How did I solve the creation of my API urls?

I wanted to be able to understand what each url did via a comment and wanted typechecking since that's TypeScript's greatest strength compared to javascript (IMO). I also wanted to create an experience for other devs to add new endpoints, and apis that was as seamless as possible.

I created a class that takes in the environment (dev, test, stage, prod, "", and etc) and passed this value to a series of classes[1-N] whose job is to create the base url for each API collection. Each ApiCollection is responsible for creating the base url for each collection of APIs. Could be our own APIs, a vendor's APIs, or even an external link. That class will pass the created base url into each subsequent api it contains. Read the code below to see a bare bones example. Once setup, it's very simple for another dev to add another endpoint to an Api class without having to touch anything else.

TLDR; basic OOP principles and lazy getters for memory optimization

@Injectable({
    providedIn: 'root'
})
export class ApiConfig {
    public apis: Apis;

    constructor(@Inject(ENVIRONMENT) private environment: string) {
        this.apis = new Apis(environment);
    }
}

export class Apis {
    readonly microservices: MicroserviceApiCollection;

    constructor(environment: string) {
        this.microservices = new MicroserviceApiCollection(environment);
    }
}

export abstract class ApiCollection {
  protected domain: any;

  constructor(environment: string) {
      const domain = this.resolveDomain(environment);
      Object.defineProperty(ApiCollection.prototype, 'domain', {
          get() {
              Object.defineProperty(this, 'domain', { value: domain });
              return this.domain;
          },
          configurable: true
      });
  }
}

export class MicroserviceApiCollection extends ApiCollection {
  public member: MemberApi;

  constructor(environment) {
      super(environment);
      this.member = new MemberApi(this.domain);
  }

  resolveDomain(environment: string): string {
      return `https://subdomain${environment}.actualdomain.com/`;
  }
}

export class Api {
  readonly base: any;

  constructor(baseUrl: string) {
      Object.defineProperty(this, 'base', {
          get() {
              Object.defineProperty(this, 'base',
              { value: baseUrl, configurable: true});
              return this.base;
          },
          enumerable: false,
          configurable: true
      });
  }

  attachProperty(name: string, value: any, enumerable?: boolean) {
      Object.defineProperty(this, name,
      { value, writable: false, configurable: true, enumerable: enumerable || true });
  }
}

export class MemberApi extends Api {

  /**
  * This comment will show up when referencing this.apiConfig.apis.microservices.member.memberInfo
  */
  get MemberInfo() {
    this.attachProperty("MemberInfo", `${this.base}basic-info`);
    return this.MemberInfo;
  }

  constructor(baseUrl: string) {
    super(baseUrl + "member/api/");
  }
}

For minikube on Docker:

Option 1: Using minikube registry

1. Check your minikube ports docker ps

You will see something like: 127.0.0.1:32769->5000/tcp It means that your minikube registry is on 32769 port for external usage, but internally it's on 5000 port.

2. Build your docker image tagging it: docker build -t 127.0.0.1:32769/hello .

3. Push the image to the minikube registry: docker push 127.0.0.1:32769/hello

4. Check if it's there: curl http://localhost:32769/v2/_catalog

5. Build some deployment using the internal port: kubectl create deployment hello --image=127.0.0.1:5000/hello

Your image is right now in minikube container, to see it write:

eval $(minikube -p <PROFILE> docker-env)
docker images

caveat: if using only one profile named "minikube" then "-p " section is redundant, but if using more then don't forget about it; Personally I delete the standard one (minikube) not to make mistakes.

Option 2: Not using registry

1. Switch to minikube container Docker: eval $(minikube -p <PROFILE> docker-env)
2. Build your image: docker build -t hello .
3. Create some deployment: kubectl create deployment hello --image=hello

At the end change the deployment ImagePullPolicy from Always to IfNotPresent:

kubectl edit deployment hello

I was getting this error, even though I have exported RouterModule from app-routing.module and imported app-routingModule in Root module(app module).

Then I identified, I've imported component in Routing Module only.

Declaring the component in my Root module(App Module) solves the problem.

declarations: [
AppComponent,
NavBarComponent,
HomeComponent,
LoginComponent],

Using ngcWebpack Plugin I got this error when not specifying a mainPath or entryModule.

Here's how to do it in Squarespace using the embed block classes to create responsiveness.

Put this into a code block:

<div class="sqs-block embed-block sqs-block-embed" data-block-type="22" >
    <div class="sqs-block-content"><div class="intrinsic" style="max-width:100%">
        <div class="embed-block-wrapper embed-block-provider-YouTube" style="padding-bottom:56.20609%;">
            <iframe allow="autoplay; fullscreen" scrolling="no" data-image-dimensions="854x480" allowfullscreen="true" src="https://www.youtube.com/embed/live_stream?channel=CHANNEL_ID_HERE" width="854" data-embed="true" frameborder="0" title="YouTube embed" class="embedly-embed" height="480">
            </iframe>
        </div>
    </div>
</div>

Tweak however you'd like!

You can send a prop from the parent and use it in child component so you will base child's state changes on the sent prop changes and you can handle this by using getDerivedStateFromProps in the child component.

This post describes how to integrate Fontawesome 5 into Angular 6 (Angular 5 and previous versions will also work, but then you have to adjust my writings)

Option 1: Add the css-Files

Pro: Every icon will be included

Contra: Every icon will be included (bigger app size because all fonts are included)

Add the following package:

npm install @fortawesome/fontawesome-free-webfonts

Afterwards add the following lines to your angular.json:

"app": {
....
"styles": [
....
"node_modules/@fortawesome/fontawesome-free-webfonts/css/fontawesome.css",
"node_modules/@fortawesome/fontawesome-free-webfonts/css/fa-regular.css",
"node_modules/@fortawesome/fontawesome-free-webfonts/css/fa-brands.css",
"node_modules/@fortawesome/fontawesome-free-webfonts/css/fa-solid.css"
],
...    
}

Option 2: Angular package

Pro: Smaller app size

Contra: You have to include every icon you want to use seperatly

Use the FontAwesome 5 Angular package:

npm install @fortawesome/angular-fontawesome

Just follow their documentation to add the icons. They use the svg-icons, so you only have to add the svgs / icons, you really use.

I've found a better way how to manage JS packages in my project with NPM Gulp/Grunt task runners. I don't like the idea to have a NPM with another layer of javascript library to handle the "automation", and my number one requirement is to simple run the npm update without any other worries about to if I need to run gulp stuff, if it successfully copied everything and vice versa.

The NPM way:

• The JS minifier is already bundled in the ASP.net core, look for bundleconfig.json so this is not an issue for me (not compiling something custom)
• The good thing about NPM is that is have a good file structure so I can always find the pre-compiled/minified versions of the dependencies under the node_modules/module/dist
• I'm using an NPM node_modules/.hooks/{eventname} script which is handling the copy/update/delete of the Project/wwwroot/lib/module/dist/.js files, you can find the documentation here https://docs.npmjs.com/misc/scripts (I'll update the script that I'm using to git once it'll be more polished) I don't need additional task runners (.js tools which I don't like) what keeps my project clean and simple.

The python way:

https://pypi.python.org/pyp... but in this case you need to maintain the sources manually

Assuming your example text is representative of all the text, one line would consume about 75 bytes on my machine:

In [3]: sys.getsizeof('usedfor zipper fasten_coat')
Out[3]: 75

Doing some rough math:

75 bytes * 8,000,000 lines / 1024 / 1024 = ~572 MB

So roughly 572 meg to store the strings alone for one of these files. Once you start adding in additional, similarly structured and sized files, you'll quickly approach your virtual address space limits, as mentioned in @ShadowRanger's answer.

If upgrading your python isn't feasible for you, or if it only kicks the can down the road (you have finite physical memory after all), you really have two options: write your results to temporary files in-between loading in and reading the input files, or write your results to a database. Since you need to further post-process the strings after aggregating them, writing to a database would be the superior approach.

You can simply add a FontAwesome icon to your select dropdown as text. You only need a few things in CSS only, the FontAwesome CSS and the unicode. For example :

select {_x000D_
  font-family: 'FontAwesome', 'Second Font name'_x000D_
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.1/css/font-awesome.min.css" rel="stylesheet"/>_x000D_
<select>_x000D_
  <option>Hi, &#xf042;</option>_x000D_
  <option>Hi, &#xf043;</option>_x000D_
  <option>Hi, &#xf044;</option>_x000D_
  <option>Hi, &#xf045;</option>_x000D_
  <option>Hi, &#xf046;</option>_x000D_
</select>

Working fiddle

The unicodes can be found when you click on an icon: Fontawesome

According to the comment below and issue on Github, the unicode in select elements won't work on OSX (yet).

Update: from the Github issue, adding multiple attribute to select element makes it work on:

OSX El Capitan 10.11.4

• Chrome version 50.0.2661.75 (64-bit)
• Sarafi version 9.1
• Firefox version 45.0.2

Define columns by min width based on viewport:

    /* Number of Cards by Row based on Viewport */
    @media (min-width: 576px) {
        .card-deck .card {
            min-width: 50.1%; /* 1 Column */
            margin-bottom: 12px;
        }
    }

    @media (min-width: 768px) {
        .card-deck .card {
            min-width: 33.4%;  /* 2 Columns */
        }
    }

    @media (min-width: 992px) {
        .card-deck .card {
            min-width: 25.1%;  /* 3 Columns */
        }
    }

    @media (min-width: 1200px) {
        .card-deck .card {
            min-width: 20.1%;  /* 4 Columns */
        }
    }

The way I would do similar thing is:

@Configuration
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
@Profile ("client_app_profile_name")
public class ClientAppConfiguration {
    //it can be left blank
}

Write similar one for the server app (without excludes).

Last step is to disable Auto Configuration from main spring boot class:

@SpringBootApplication
public class SomeApplication extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(SomeApplication.class);
    }

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SomeApplication.class);
    }
}

Change: @SpringBootApplication into:

@Configuration 
@ComponentScan

This should do the job. Now, the dependencies that I excluded in the example might be incomplete. They were enough for me, but im not sure if its all to completely disable database related libraries. Check the list below to be sure:

http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#auto-configuration-classes

Hope that helps

A fresh answer for Spring Boot 2.2 is required as server.connection-timeout=5000 is deprecated. Each server behaves differently, so server specific properties are recommended instead.

SpringBoot embeds Tomcat by default, if you haven't reconfigured it with Jetty or something else. Use server specific application properties like server.tomcat.connection-timeout or server.jetty.idle-timeout.

Simply with native html & css :

<div class="tooltip">Hover over me
  <span class="tooltiptext">Tooltip text</span>
</div>

/* Tooltip container */
.tooltip {
  position: relative;
  display: inline-block;
  border-bottom: 1px dotted black; /* If you want dots under the hoverable text */
}

/* Tooltip text */
.tooltip .tooltiptext {
  visibility: hidden;
  width: 120px;
  background-color: #555;
  color: #fff;
  text-align: center;
  padding: 5px 0;
  border-radius: 6px;

  /* Position the tooltip text */
  position: absolute;
  z-index: 1;
  bottom: 125%;
  left: 50%;
  margin-left: -60px;

  /* Fade in tooltip */
  opacity: 0;
  transition: opacity 0.3s;
}

/* Tooltip arrow */
.tooltip .tooltiptext::after {
  content: "";
  position: absolute;
  top: 100%;
  left: 50%;
  margin-left: -5px;
  border-width: 5px;
  border-style: solid;
  border-color: #555 transparent transparent transparent;
}

/* Show the tooltip text when you mouse over the tooltip container */
.tooltip:hover .tooltiptext {
  visibility: visible;
  opacity: 1;
}

Here is the source of the example from w3schools

At eBay it’s the kabob.

Also heard it called the snowman or sushi roll.

You need to provide a key.

Try doing this in your ListView Rows if you have a key property:

<TouchableHighlight key={item.key} underlayColor='#dddddd'>

If not, try just adding the item as the key:

<TouchableHighlight key={item} underlayColor='#dddddd'>

This can be achieved with ES6 template literals:

<input className={`base-input-class ${class1} ${class2}`}>

In my case, for a stateless component that received the ref with forwardRef, I had to do what it is said here https://itnext.io/reusing-the-ref-from-forwardref-with-react-hooks-4ce9df693dd

From this (onClick doesn't have access to the equivalent of 'this')

const Com = forwardRef((props, ref) => {
  return <input ref={ref} onClick={() => {console.log(ref.current} } />
})

To this (it works)

const useCombinedRefs = (...refs) => {
  const targetRef = React.useRef()

  useEffect(() => {
    refs.forEach(ref => {
      if (!ref) return

      if (typeof ref === 'function') ref(targetRef.current)
      else ref.current = targetRef.current
    })
  }, [refs])

  return targetRef
}

const Com = forwardRef((props, ref) => {
  const innerRef = useRef()
  const combinedRef = useCombinedRefs(ref, innerRef)

  return <input ref={combinedRef } onClick={() => {console.log(combinedRef .current} } />
})

StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            Log.e("Rest response",response);
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e("Rest response",error.toString());
        }
    }){
        @Override
        protected Map<String,String> getParams(){
            Map<String,String> params = new HashMap<String,String>();
            params.put("name","xyz");
            return params;
        }

        @Override
        public Map<String,String> getHeaders() throws AuthFailureError {
            Map<String,String> params = new HashMap<String,String>();
            params.put("content-type","application/fesf");
            return params;
        }

    };

    requestQueue.add(stringRequest);

First you need to access the navigation drawer in your MainActivity(or the calling activity) like this:

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);

Then you need to remove the header layout from the activity_main.xml because the layout will be inflated programatically in the MainActivity. Your activity_main.xml should look like this:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout            

xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">

<include
    layout="@layout/app_bar_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:menu="@menu/activity_main_drawer" />

    </android.support.v4.widget.DrawerLayout>

Then in your MainActivity, we inflate the nav_header_main layout and get access to its views, in this case the ImageView and TextView

//inflate header layout
View navView =  navigationView.inflateHeaderView(R.layout.nav_header_main);
//reference to views
ImageView imgvw = (ImageView)navView.findViewById(R.id.imageView);
TextView tv = (TextView)navView.findViewById(R.id.textview);
//set views
imgvw.setImageResource(R.drawable.your_image);
tv.setText("new text");

navigationView.setNavigationItemSelectedListener(this);

Ok, I think I've figured what the issue is here. It was to do with the version of watchman I was running.

In a new shell, run brew update then: brew unlink watchman then: brew install watchman

now, you can run react-native start from your project folder

I leave this shell open, create a new shell window and run: react-native run-android from my project folder. All is right with the world.

ps. I was originally on version 3.2 of watchman. This upgraded me to 3.7.

pps. I'm new to this so that might not be the swiftest route to the solution but it has worked for me.

* MORE INFO FOR RUNNING/DEBUGGING ON A DEVICE *

You might find that if you deploy your app to your Android device rather than an emulater you get a red screen of death with an error saying Unable to load JS Bundle. You need to set the debug server for your device to be your computer running react...either its name OR IP address.

1. Press the device Menu button
2. Select Dev Settings
3. Select Debug server host for device or Change Bundle Location
4. Type in your machine's IP and Reload JS plus the react port e.g. 192.168.1.10:8081

Check file/folder permissions

I struggled with this error today, and no amount of cache, config, autoload clears did anything to help. To add to the confusion, the error was thrown if initiated by a web request, but accessing the class in tinker worked fine.

After checking for typo's, syntax errors, and incorrect namespaces, I ended up discovering it was a file permission issue. The folder and file containing my class did not have appropriate permissions so it was throwing this error. The incorrect permission level I had was 771 (folder) and 660 (file), by changing it to 775 and 664 I was able to get it working.

My understanding of the different behaviors is that when running from the command line it was reading the file as my user (which had all the permissions it needed), but when initiated from the web it uses the "other" permission group which could do nothing.

For me, the problem was twofold: First, the version of IIS I was dealing with didn't know about the .woff2 MIME type, only about .woff. I fixed that using IIS Manager at the server level, not at the web app level, so the setting wouldn't get overridden with each new app deployment. (Under IIS Manager, I went to MIME types, and added the missing .woff2, then updated .woff.)

Second, and more importantly, I was bundling bootstrap.css along with some other files as "~/bundles/css/site". Meanwhile, my font files were in "~/fonts". bootstrap.css looks for the glyphicon fonts in "../fonts", which translated to "~/bundles/fonts" -- wrong path.

In other words, my bundle path was one directory too deep. I renamed it to "~/bundles/siteCss", and updated all the references to it that I found in my project. Now bootstrap looked in "~/fonts" for the glyphicon files, which worked. Problem solved.

Before I fixed the second problem above, none of the glyphicon font files were loading. The symptom was that all instances of glyphicon glyphs in the project just showed an empty box. However, this symptom only occurred in the deployed versions of the web app, not on my dev machine. I'm still not sure why that was the case.

You could use the CopyWebpackPlugin. It's working just like this:

module.exports = {
  plugins: [
    new CopyWebpackPlugin([{
      from: './*.html'
    }])
  ]
}

I know the accepted answer is great but for anyone who is looking for a hover like feel you can use setTimeout on mouseover and save the handle in a map (of let's say list ids to setTimeout Handle). On mouseover clear the handle from setTimeout and delete it from the map

onMouseOver={() => this.onMouseOver(someId)}
onMouseOut={() => this.onMouseOut(someId)

And implement the map as follows:

onMouseOver(listId: string) {
  this.setState({
    ... // whatever
  });

  const handle = setTimeout(() => {
    scrollPreviewToComponentId(listId);
  }, 1000); // Replace 1000ms with any time you feel is good enough for your hover action
  this.hoverHandleMap[listId] = handle;
}

onMouseOut(listId: string) {
  this.setState({
    ... // whatever
  });

  const handle = this.hoverHandleMap[listId];
  clearTimeout(handle);
  delete this.hoverHandleMap[listId];
}

And the map is like so,

hoverHandleMap: { [listId: string]: NodeJS.Timeout } = {};

I prefer onMouseOver and onMouseOut because it also applies to all the children in the HTMLElement. If this is not required you may use onMouseEnter and onMouseLeave respectively.

In my case, I needed to change the color of just one menu item - "Logout". I had to run a recursion and changed the title color:

NavigationView nvDrawer;
Menu menu = nvDrawer.getMenu();
    for (int i = 0; i < menu.size(); i ++){
        MenuItem menuItem = menu.getItem(i);

        if (menuItem.getTitle().equals("Logout")){

            SpannableString spanString = new SpannableString(menuItem.getTitle().toString());
            spanString.setSpan(new ForegroundColorSpan(getResources().getColor(R.color.red)), 0, spanString.length(), 0);
            menuItem.setTitle(spanString);

        }

    }

I did this in the Activity's onCreate method.

Use Test-Path:

if (!(Test-Path $exactadminfile) -and !(Test-Path $userfile)) {
  Write-Warning "$userFile absent from both locations"
}

Placing the above code in your ForEach loop should do what you want

recyclerview.addItemDecoration(new DividerItemDecoration(this, 0));

Where 0 is Horizontal and 1 is Veritical

Make a selector for Individaual item of Nav Drawer

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/darkBlue" android:state_pressed="true"/>
    <item android:drawable="@color/darkBlue" android:state_checked="true"/>
    <item android:drawable="@color/textBlue" />
</selector>

Make a few changes in your NavigationView

<android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:itemBackground="@drawable/drawer_item"
        android:background="@color/textBlue"
        app:itemIconTint="@color/white"
        app:itemTextColor="@color/white"
        app:menu="@menu/activity_main_drawer"
        />

I believe app:itemBackground expects a drawable. So follow the steps below :

Make a drawable file highlight_color.xml with following contents :

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
     <solid android:color="YOUR HIGHLIGHT COLOR"/>
</shape>

Make another drawable file nav_item_drawable.xml with following contents:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:drawable="@drawable/highlight_color" android:state_checked="true"/>
</selector>

Finally add app:itemBackground tag in the NavView :

<android.support.design.widget.NavigationView
android:id="@+id/activity_main_navigationview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/drawer_header"
app:itemIconTint="@color/black"
app:itemTextColor="@color/primary_text"
app:itemBackground="@drawable/nav_item_drawable"
app:menu="@menu/menu_drawer">

here the highlight_color.xml file defines a solid color drawable for the background. Later this color drawable is assigned to nav_item_drawable.xml selector.

This worked for me. Hopefully this will help.

********************************************** UPDATED **********************************************

Though the above mentioned answer gives you fine control over some properties, but the way I am about to describe feels more SOLID and is a bit COOLER.

So what you can do is, you can define a ThemeOverlay in the styles.xml for the NavigationView like this :

    <style name="ThemeOverlay.AppCompat.navTheme">

        <!-- Color of text and icon when SELECTED -->
        <item name="colorPrimary">@color/color_of_your_choice</item> 

        <!-- Background color when SELECTED -->
        <item name="colorControlHighlight">@color/color_of_your_choice</item> 

    </style>

now apply this ThemeOverlay to app:theme attribute of NavigationView, like this:

<android.support.design.widget.NavigationView
android:id="@+id/activity_main_navigationview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:theme="@style/ThemeOverlay.AppCompat.navTheme"
app:headerLayout="@layout/drawer_header"
app:menu="@menu/menu_drawer">

I hope this will help.

I had similar error. When i use

<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">

    <item name="colorPrimary">#673AB7</item>
    <item name="colorPrimaryDark">#512DA8</item>
    <item name="colorAccent">#00BCD4</item>
    <item name="android:textColorPrimary">#212121</item>
    <item name="android:textColorSecondary">#727272</item>

</style>

works for me when i remove the android:textColorPrimary and android:textColorSecondary theme items.

<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">

    <item name="colorPrimary">#673AB7</item>
    <item name="colorPrimaryDark">#512DA8</item>
    <item name="colorAccent">#00BCD4</item>

</style>

Try working with a very simple App theme to start off with.

EDIT:

This tutorial will help. My understanding is that using "android:textColorPrimary" requires minimum api level 21. Using the same tag without "android:" uses the design support library. Any support library widget will try to find the "textColorPrimary" item instead of "android:textColorPrimary" and if it fails to find the same it throws the above mentioned error.

Using NewRequest just to create an URL is an overkill. Use the net/url package:

package main

import (
    "fmt"
    "net/url"
)

func main() {
    base, err := url.Parse("http://www.example.com")
    if err != nil {
        return
    }

    // Path params
    base.Path += "this will get automatically encoded"

    // Query params
    params := url.Values{}
    params.Add("q", "this will get encoded as well")
    base.RawQuery = params.Encode() 

    fmt.Printf("Encoded URL is %q\n", base.String())
}

Playground: https://play.golang.org/p/YCTvdluws-r

You shouldn't use both ngRoute and UI-router. Here's a sample code for UI-router:

repoApp.config(function($stateProvider, $urlRouterProvider) {_x000D_
  _x000D_
  $stateProvider_x000D_
    .state('state1', {_x000D_
      url: "/state1",_x000D_
      templateUrl: "partials/state1.html",_x000D_
      controller: 'YourCtrl'_x000D_
    })_x000D_
    _x000D_
    .state('state2', {_x000D_
      url: "/state2",_x000D_
      templateUrl: "partials/state2.html",_x000D_
      controller: 'YourOtherCtrl'_x000D_
    });_x000D_
    $urlRouterProvider.otherwise("/state1");_x000D_
});_x000D_
//etc.

You can find a great answer on the difference between these two in this thread: What is the difference between angular-route and angular-ui-router?

You can also consult UI-Router's docs here: https://github.com/angular-ui/ui-router

I wanted a solution that did not create any extra objects (ie listeners) that would have to be garbage collected later, and did not require nesting a view holder inside an adapter class.

In the ViewHolder class

private static class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

        private final TextView ....// declare the fields in your view
        private ClickHandler ClickHandler;

        public MyHolder(final View itemView) {
            super(itemView);
            nameField = (TextView) itemView.findViewById(R.id.name);
            //find other fields here...
            Button myButton = (Button) itemView.findViewById(R.id.my_button);
            myButton.setOnClickListener(this);
        }
        ...
        @Override
        public void onClick(final View view) {
            if (clickHandler != null) {
                clickHandler.onMyButtonClicked(getAdapterPosition());
            }
        }

Points to note: the ClickHandler interface is defined, but not initialized here, so there is no assumption in the onClick method that it was ever initialized.

The ClickHandler interface looks like this:

private interface ClickHandler {
    void onMyButtonClicked(final int position);
} 

In the adapter, set an instance of 'ClickHandler' in the constructor, and override onBindViewHolder, to initialize `clickHandler' on the view holder:

private class MyAdapter extends ...{

    private final ClickHandler clickHandler;

    public MyAdapter(final ClickHandler clickHandler) {
        super(...);
        this.clickHandler = clickHandler;
    }

    @Override
    public void onBindViewHolder(final MyViewHolder viewHolder, final int position) {
        super.onBindViewHolder(viewHolder, position);
        viewHolder.clickHandler = this.clickHandler;
    }

Note: I know that viewHolder.clickHandler is potentially getting set multiple times with the exact same value, but this is cheaper than checking for null and branching, and there is no memory cost, just an extra instruction.

Finally, when you create the adapter, you are forced to pass a ClickHandlerinstance to the constructor, as so:

adapter = new MyAdapter(new ClickHandler() {
    @Override
    public void onMyButtonClicked(final int position) {
        final MyModel model = adapter.getItem(position);
        //do something with the model where the button was clicked
    }
});

Note that adapter is a member variable here, not a local variable

Per the docs:

Mac OS X

1. Download Visual Studio Code for Mac OS X.
2. Double-click on VSCode-osx.zip to expand the contents.
3. Drag Visual Studio Code.app to the Applications folder, making it available in the Launchpad.
4. Add VS Code to your Dock by right-clicking on the icon and choosing Options, Keep in Dock.

Tip: If you want to run VS Code from the terminal, append the following to your ~/.bash_profile file (~/.zshrc in case you use zsh).

code () { VSCODE_CWD="$PWD" open -n -b "com.microsoft.VSCode" --args $* ;}

Now, you can simply type code . in any folder to start editing files in that folder.

Tip: You can also add it to VS Code Insiders build by changing "com.microsoft.VSCodeInsiders". Also if you don't to type the whole word code, just change it to c.

Linux

1. Download Visual Studio Code for Linux.
2. Make a new folder and extract VSCode-linux-x64.zip inside that folder.
3. Double click on Code to run Visual Studio Code.

Tip: If you want to run VS Code from the terminal, create the following link substituting /path/to/vscode/Code with the absolute path to the Code executable

sudo ln -s /path/to/vscode/Code /usr/local/bin/code

Now, you can simply type code . in any folder to start editing files in that folder.

For me, the problem was that I copied something from an example and used

<item name="android:windowTranslucentStatus">true</item>

just removing this fixed my problem.

You can use Toolbar inside the fragment and it is easy to handle. First add Toolbar to layout of the fragment

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:fitsSystemWindows="true"
    android:minHeight="?attr/actionBarSize"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:background="?attr/colorPrimaryDark">
</android.support.v7.widget.Toolbar>

Inside the onCreateView Method in the fragment you can handle the toolbar like this.

 Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
 toolbar.setTitle("Title");
 toolbar.setNavigationIcon(R.drawable.ic_arrow_back);

IT will set the toolbar,title and the back arrow navigation to toolbar.You can set any icon to setNavigationIcon method.

If you need to trigger any event when click toolbar navigation icon you can use this.

 toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
           //handle any click event
    });

If your activity have navigation drawer you may need to open that when click the navigation back button. you can open that drawer like this.

 toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            DrawerLayout drawer = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);
            drawer.openDrawer(Gravity.START);
        }
    });

Full code is here

 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    //inflate the layout to the fragement
    view = inflater.inflate(R.layout.layout_user,container,false);

    //initialize the toolbar
    Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
    toolbar.setTitle("Title");
    toolbar.setNavigationIcon(R.drawable.ic_arrow_back);
    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //open navigation drawer when click navigation back button
            DrawerLayout drawer = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);
            drawer.openDrawer(Gravity.START);
        }
    });
    return view;
}

To change the navigation icon you can use:

Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.my_icon);

To change the overflow icon you can use the method:

toolbar.setOverflowIcon(ContextCompat.getDrawable(this, R.drawable.ic_my_menu);

If you would like to change the color of the icons you can use:

with a Material Components Theme (with a MaterialToolbar for example):

<com.google.android.material.appbar.MaterialToolbar
    android:theme="@style/MyThemeOverlay_Toolbar"
    ...>

  <style name="MyThemeOverlay_Toolbar" parent="ThemeOverlay.MaterialComponents.Toolbar.Primary">
    <!-- color used by navigation icon and overflow icon -->
    <item name="colorOnPrimary">@color/myColor</item>
  </style>

With an AppCompat Theme:

<android.support.v7.widget.Toolbar
  app:theme="@style/ThemeToolbar" />


<style name="ThemeToolbar" parent="Theme.AppCompat.Light">

   <!-- navigation icon color -->
   <item name="colorControlNormal">@color/my_color</item>

    <!-- color of the menu overflow icon -->
    <item name="android:textColorSecondary">@color/my_color</item>
</style>

You can also change the overflow icon overriding in the app theme the actionOverflowButtonStyle attribute:

With a Material Components Theme:

<style name="AppTheme.Base" parent="Theme.MaterialComponents.DayNight">
    <item name="actionOverflowButtonStyle">@style/OverFlow</item>
</style>

<style name="OverFlow" parent="Widget.AppCompat.ActionButton.Overflow">
    <item name="srcCompat">@drawable/my_overflow_menu</item>
</style>

With an AppCompat theme:

<style name="AppTheme.Base" parent="Theme.AppCompat.Light">
    <item name="actionOverflowButtonStyle">@style/OverFlow</item>
</style>

<style name="OverFlow" parent="Widget.AppCompat.ActionButton.Overflow">
    <item name="srcCompat">@drawable/my_overflow_menu</item>
</style>

I was using previously this code:

Toolbar toolbar =  findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

and extended AppCompatActivity also but I was getting the same error. So in place of using Toolbar class, I have imported the below class and it worked for me:

android.support.v7.widget.Toolbar

iconView = (ImageView) itemLayoutView .findViewById(R.id.iconId);

        itemLayoutView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Intent intent = new Intent(v.getContext(), SecondPage.class);
                v.getContext().startActivity(intent);
                Toast.makeText(v.getContext(), "os version is: " + feed.getTitle(), Toast.LENGTH_SHORT).show();
            }
        });

   <!-- ToolBar -->
    <style name="ToolBarTheme.ToolBarStyle"    parent="ThemeOverlay.AppCompat.Dark.ActionBar">
        <item name="android:textColorPrimary">@android:color/white</item>
        <item name="android:textColor">@color/white</item>
        <item name="android:textColorPrimaryInverse">@color/white</item>
    </style>

Too late to post, this worked for me to change the color of the back button

For those who are still getting blank response with $request->getContent(), you can use:

$request->all()

e.g:

public function foo(Request $request){
   $bodyContent = $request->all();
}

In IIS you can declare the mime type for WOFF2 font files by adding the following to your project's web.config:

<system.webServer>
  <staticContent>
    <remove fileExtension=".woff2" />
    <mimeMap fileExtension=".woff2" mimeType="font/woff2" />
  </staticContent>
</system.webServer>

Update: The mime type may be changing according to the latest W3C Editor's Draft WOFF2 spec. See Appendix A: Internet Media Type Registration section 6.5. WOFF 2.0 which states the latest proposed format is font/woff2

If you need to download only text file into String you can use this simple way, Swift 5:

let list = try? String(contentsOf: URL(string: "https://example.com/file.txt")!)

In case you want non optional result or error handling:

do {
    let list = try String(contentsOf: URL(string: "https://example.com/file.txt")!)
}
catch {
    // Handle error here
}

You should know that network operations may take some time, to prevent it from running in main thread and locking your UI, you may want to execute the code asynchronously, for example:

DispatchQueue.global().async {
    let list = try? String(contentsOf: URL(string: "https://example.com/file.txt")!)
}

android.widget.Button.setOnClickListener(android.view.View$OnClickListener)' on a null object reference

Because Submit button is inside login_modal so you need to use loginDialog view to access button:

Submit = (Button)loginDialog.findViewById(R.id.Submit);

Try to check here

res >> values >> styles.xml

make sure that there no code like this

<item name="windowActionBar">false</item>

if there are code like that, you can disable for a while, or erase it

To have an animated hamburger icon you should use DrawerLayout with ActionBarDrawerToggle and enable the icon for the ActionBar and for the ActionBarDrawerToggle.

Example:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle mDrawerToggle;

setSupportActionBar(toolbar);
final ActionBar actionBar = getSupportActionBar();

if (actionBar != null)
{
   actionBar.setDisplayHomeAsUpEnabled(true);
   mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.hello_world, R.string.hello_world)
   {

      public void onDrawerClosed(View view)
      {
         supportInvalidateOptionsMenu();
         //drawerOpened = false;
      }

      public void onDrawerOpened(View drawerView)
      {
         supportInvalidateOptionsMenu();
         //drawerOpened = true;
      }
   };
   mDrawerToggle.setDrawerIndicatorEnabled(true);
   drawerLayout.setDrawerListener(mDrawerToggle);
   mDrawerToggle.syncState();
}

Also, you need to add these methods to your Activity:

@Override
protected void onPostCreate(Bundle savedInstanceState)
{
    super.onPostCreate(savedInstanceState);
    mDrawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig)
{
    super.onConfigurationChanged(newConfig);
    mDrawerToggle.onConfigurationChanged(newConfig);
}

Here's my attempt at doing this:

Step 1: Create a style named SearchViewStyle

<style name="SearchViewStyle" parent="Widget.AppCompat.SearchView">
    <!-- Gets rid of the search icon -->
    <item name="searchIcon">@drawable/search</item>
    <!-- Gets rid of the "underline" in the text -->
    <item name="queryBackground">@null</item>
    <!-- Gets rid of the search icon when the SearchView is expanded -->
    <item name="searchHintIcon">@null</item>
    <!-- The hint text that appears when the user has not typed anything -->
    <item name="queryHint">@string/search_hint</item>
</style>

Step 2: Create a layout named simple_search_view_item.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.SearchView
    android:layout_gravity="end"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    style="@style/SearchViewStyle"
    xmlns:android="http://schemas.android.com/apk/res/android" />  

Step 3: Create a menu item for this search view

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        app:actionLayout="@layout/simple_search_view_item"
        android:title="@string/search"
        android:icon="@drawable/search"
        app:showAsAction="always" />
</menu>  

Step 4: Inflate the menu

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_searchable_activity, menu);
    return true;
}  

Result:

The only thing I wasn't able to do was to make it fill the entire width of the Toolbar. If someone could help me do that then that'd be golden.

When you use Object.defineProperties, by default writable is set to false, so _year and edition are actually read only properties.

Explicitly set them to writable: true:

_year: {
    value: 2004,
    writable: true
},

edition: {
    value: 1,
    writable: true
},

Check out MDN for this method.

writable
true if and only if the value associated with the property may be changed with an assignment operator.
Defaults to false.

I was using a Dependency Injection - ButterKnife and this problem arised because I had not binded the view.

So inside onCreate() I just inserted this line:

ButterKnife.bind(this);

My RecyclerView declaration with Dependency Injection:

@BindView(R.id.recyclerview)
RecyclerView recyclerView;

In XML

 <androidx.appcompat.widget.Toolbar
  android:id="@+id/main_toolbar"
  android:layout_width="match_parent"
  android:layout_height="?attr/actionBarSize"
  app:layout_scrollFlags="scroll|enterAlways">
 </androidx.appcompat.widget.Toolbar>

Kotlin: In fragment.kt -> onCreateView()

setHasOptionsMenu(true)

val toolbar = view.findViewById<Toolbar>(R.id.main_toolbar)

(activity as? AppCompatActivity)?.setSupportActionBar(toolbar)

(activity as? AppCompatActivity)?.supportActionBar?.show()

-> onCreateOptionsMenu()

   override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
       inflater.inflate(R.menu.app_main_menu,menu)
       super.onCreateOptionsMenu(menu, inflater)
   }

->onOptionsItemSelected()

   override fun onOptionsItemSelected(item: MenuItem): Boolean {
        return when (item.itemId) {
             R.id.selected_id->{//to_do}
             else -> super.onOptionsItemSelected(item)
        }
    }

If we follow the activity template created by Android Studios, it's the AppBarLayout that needs to have an android theme of AppBarOverlay, which you should define in the your styles.xml. That should give you your white color toobar/actionbar color text.

<android.support.design.widget.AppBarLayout
    android:id="@+id/app_bar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">  ...

In styles.xml, make sure the following exists:

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

Be aware that the new version (5) of font awesome uses "fas" or "fab" instead of "fa" prefix.

Quoted from their website:

The fa prefix has been deprecated in version 5. The new default is the fas solid style and the fab style for brands.

This is why my fonts were showing blank squares. Now fixed.

Example code:

<a class="nav-link" href="//www.facebook.com/xxx" target="_blank"><i class="fab fa-facebook-f"></i></a>

See: https://fontawesome.com/icons/facebook-f?style=brands

If you don't want it to add it to a link, you can just enclose it within a span and that would work.

<span id='clickableAwesomeFont'><i class="fa fa-behance-square fa-4x"></span>

in your css, then you can:

#clickableAwesomeFont {
     cursor: pointer
}

Then in java script, you can just add a click handler.

In cases where it's actually not a link, I think this is much cleaner and using a link would be changing its semantics and abusing its meaning.

Another solution that might work for you is to not declare your toolbar as the app's action bar ( by setActionBar or setSupportActionBar ) and set the back icon in your onActivityCreated using the code mentioned in another answer on this page

final Drawable upArrow = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
upArrow.setColorFilter(getResources().getColor(R.color.grey), PorterDuff.Mode.SRC_ATOP);
toolbar.setNavigationIcon(upArrow);

Now, you will not get the onOptionItemSelected callback when you press the back button. However, you can register for that using setNavigationOnClickListener. This is what i do:

toolbar.setNavigationOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        getActivity().onBackPressed(); //or whatever you used to do on your onOptionItemSelected's android.R.id.home callback
    }
});

I'm not sure if it will work if you work with menu items.

Try to do this:

getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setDisplayShowTitleEnabled(false);

and if you made your custom toolbar (which i presume you did) then you can use the simplest way possible to do this:

toolbarTitle = (TextView)findViewById(R.id.toolbar_title);
toolbarSubTitle = (TextView)findViewById(R.id.toolbar_subtitle);
toolbarTitle.setText("Title");
toolbarSubTitle.setText("Subtitle");

Same goes for any other views you put in your toolbar. Hope it helps.

To access the index in this case you access the name attribute:

In [182]:

df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
def rowFunc(row):
    return row['a'] + row['b'] * row['c']

def rowIndex(row):
    return row.name
df['d'] = df.apply(rowFunc, axis=1)
df['rowIndex'] = df.apply(rowIndex, axis=1)
df
Out[182]:
   a  b  c   d  rowIndex
0  1  2  3   7         0
1  4  5  6  34         1

Note that if this is really what you are trying to do that the following works and is much faster:

In [198]:

df['d'] = df['a'] + df['b'] * df['c']
df
Out[198]:
   a  b  c   d
0  1  2  3   7
1  4  5  6  34

In [199]:

%timeit df['a'] + df['b'] * df['c']
%timeit df.apply(rowIndex, axis=1)
10000 loops, best of 3: 163 µs per loop
1000 loops, best of 3: 286 µs per loop

EDIT

Looking at this question 3+ years later, you could just do:

In[15]:
df['d'],df['rowIndex'] = df['a'] + df['b'] * df['c'], df.index
df

Out[15]: 
   a  b  c   d  rowIndex
0  1  2  3   7         0
1  4  5  6  34         1

but assuming it isn't as trivial as this, whatever your rowFunc is really doing, you should look to use the vectorised functions, and then use them against the df index:

In[16]:
df['newCol'] = df['a'] + df['b'] + df['c'] + df.index
df

Out[16]: 
   a  b  c   d  rowIndex  newCol
0  1  2  3   7         0       6
1  4  5  6  34         1      16

In the scenario you would NOT like to use the onChange handler on the input DOM, you can use the onClick property as an alternative. The defaultChecked, the condition may leave a fixed state for v16 IINM.

 class CrossOutCheckbox extends Component {
      constructor(init){
          super(init);
          this.handleChange = this.handleChange.bind(this);
      }
      handleChange({target}){
          if (target.checked){
             target.removeAttribute('checked');
             target.parentNode.style.textDecoration = "";
          } else {
             target.setAttribute('checked', true);
             target.parentNode.style.textDecoration = "line-through";
          }
      }
      render(){
         return (
            <span>
              <label style={{textDecoration: this.props.complete?"line-through":""}}>
                 <input type="checkbox"
                        onClick={this.handleChange}
                        defaultChecked={this.props.complete}
                  />
              </label>
                {this.props.text}
            </span>
        )
    }
 }

I hope this helps someone in the future.

For anyone looking for a Xamarin implementation (since events are done differently in C#), I simply created this NavClickHandler class as follows:

public class NavClickHandler : Java.Lang.Object, View.IOnClickListener
{
    private Activity mActivity;
    public NavClickHandler(Activity activity)
    {
        this.mActivity = activity;
    }
    public void OnClick(View v)
    {
        DrawerLayout drawer = (DrawerLayout)mActivity.FindViewById(Resource.Id.drawer_layout);
        if (drawer.IsDrawerOpen(GravityCompat.Start))
        {
            drawer.CloseDrawer(GravityCompat.Start);
        }
        else
        {
            drawer.OpenDrawer(GravityCompat.Start);
        }
    }
}

Then, assigned a custom hamburger menu button like this:

        SupportActionBar.SetDisplayHomeAsUpEnabled(true);
        SupportActionBar.SetDefaultDisplayHomeAsUpEnabled(false);
        this.drawerToggle.DrawerIndicatorEnabled = false;
        this.drawerToggle.SetHomeAsUpIndicator(Resource.Drawable.MenuButton);

And finally, assigned the drawer menu toggler a ToolbarNavigationClickListener of the class type I created earlier:

        this.drawerToggle.ToolbarNavigationClickListener = new NavClickHandler(this);

And then you've got a custom menu button, with click events handled.

The solutions above didn't help me. I've tried 2 first steps from this link. Worked fine for me. But don't forget to

import com.melnykov.fab.FloatingActionButton; 

instead of

import android.support.design.widget.FloatingActionButton;

in your MainActivity.java

i added

<android.support.v7.widget.Toolbar
...
android:translationZ="5dp"/>

in toolbar description and it works for me. Using 5.0+

I used the method below which really is a conundrum of all the ones above. I also found that onOptionsItemSelected is never activated.

    mDrawerToggle.setDrawerIndicatorEnabled(false);
    getSupportActionBar().setHomeButtonEnabled(true);

    Toolbar toolbar = (Toolbar) findViewById(R.id.tool_bar);
    if (toolbar != null) {
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onBackPressed();
            }
        });
    }

A combination of

android:padding="0dp" In the xml for the Toolbar

and

mToolbar.setContentInsetsAbsolute(0, 0) In the code

This worked for me.

New functionality in the framework and support libs allow exactly this. There are three 'pieces of the puzzle':

1. Using Toolbar so that you can embed your action bar into your view hierarchy.
2. Making DrawerLayout fitsSystemWindows so that it is layed out behind the system bars.
3. Disabling Theme.Material's normal status bar coloring so that DrawerLayout can draw there instead.

I'll assume that you will use the new appcompat.

First, your layout should look like this:

<!-- The important thing to note here is the added fitSystemWindows -->
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/my_drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <!-- Your normal content view -->
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <!-- We use a Toolbar so that our drawer can be displayed
             in front of the action bar -->
        <android.support.v7.widget.Toolbar  
            android:id="@+id/my_awesome_toolbar"
            android:layout_height="wrap_content"
            android:layout_width="match_parent"
            android:minHeight="?attr/actionBarSize"
            android:background="?attr/colorPrimary" />

        <!-- The rest of your content view -->

    </LinearLayout>

    <!-- Your drawer view. This can be any view, LinearLayout
         is just an example. As we have set fitSystemWindows=true
         this will be displayed under the status bar. -->
    <LinearLayout
        android:layout_width="304dp"
        android:layout_height="match_parent"
        android:layout_gravity="left|start"
        android:fitsSystemWindows="true">

        <!-- Your drawer content -->

    </LinearLayout>

</android.support.v4.widget.DrawerLayout>

Then in your Activity/Fragment:

public void onCreate(Bundled savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Your normal setup. Blah blah ...

    // As we're using a Toolbar, we should retrieve it and set it
    // to be our ActionBar
    Toolbar toolbar = (...) findViewById(R.id.my_awesome_toolbar);
    setSupportActionBar(toolbar);

    // Now retrieve the DrawerLayout so that we can set the status bar color.
    // This only takes effect on Lollipop, or when using translucentStatusBar
    // on KitKat.
    DrawerLayout drawerLayout = (...) findViewById(R.id.my_drawer_layout);
    drawerLayout.setStatusBarBackgroundColor(yourChosenColor);
}

Then you need to make sure that the DrawerLayout is visible behind the status bar. You do that by changing your values-v21 theme:

values-v21/themes.xml

<style name="Theme.MyApp" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
    <item name="android:windowTranslucentStatus">true</item>
</style>

Note: If a <fragment android:name="fragments.NavigationDrawerFragment"> is used instead of

<LinearLayout
    android:layout_width="304dp"
    android:layout_height="match_parent"
    android:layout_gravity="left|start"
    android:fitsSystemWindows="true">

    <!-- Your drawer content -->

</LinearLayout>

the actual layout, the desired effect will be achieved if you call fitsSystemWindows(boolean) on a view that you return from onCreateView method.

@Override
public View onCreateView(LayoutInflater inflater, 
                         ViewGroup container,
                         Bundle savedInstanceState) {
    View mDrawerListView = inflater.inflate(
        R.layout.fragment_navigation_drawer, container, false);
    mDrawerListView.setFitsSystemWindows(true);
    return mDrawerListView;
}

There's no need for you to use super-call of the ActionBarDrawerToggle which requires the Toolbar. This means instead of using the following constructor:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

You should use this one:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)

So basically the only thing you have to do is to remove your custom drawable:

super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);

More about the "new" ActionBarDrawerToggle in the Docs (click).

First, you should know now the android.support.v4.app.ActionBarDrawerToggle is deprecated.

You must replace that with android.support.v7.app.ActionBarDrawerToggle.

Here is my example and I use the new Toolbar to replace the ActionBar.

MainActivity.java

public class MainActivity extends ActionBarActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Toolbar mToolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(mToolbar);
    DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(
        this,  mDrawerLayout, mToolbar,
        R.string.navigation_drawer_open, R.string.navigation_drawer_close
    );
    mDrawerLayout.setDrawerListener(mDrawerToggle);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);
    mDrawerToggle.syncState();
}

styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light">
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="spinBars">true</item>
    <item name="color">@android:color/white</item>
</style>

You can read the documents on AndroidDocument#DrawerArrowToggle_spinBars

This attribute is the key to implement the menu-to-arrow animation.

public static int DrawerArrowToggle_spinBars

Whether bars should rotate or not during transition
Must be a boolean value, either "true" or "false".

So, you set this: <item name="spinBars">true</item>.

Then the animation can be presented.

Hope this can help you.

if you want to change only the colour of the flag on hover use this:

http://jsfiddle.net/uvamhedx/

.fa-flag:hover {_x000D_
    color: red;_x000D_
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>_x000D_
_x000D_
<i class="fa fa-flag fa-3x"></i>

1. Just add the font awesome class like this:

   class="fa fa-plus-circle fa-3x"
   

   (You can increase the size as per 5x, 7x, 9x..)

2. You can also add custom CSS.

Different connections pools have different configs.

For example Tomcat (default) expects:

spring.datasource.ourdb.url=...

and HikariCP will be happy with:

spring.datasource.ourdb.jdbc-url=...

We can satisfy both without boilerplate configuration:

spring.datasource.ourdb.jdbc-url=${spring.datasource.ourdb.url}

There is no property to define connection pool provider.

Take a look at source DataSourceBuilder.java

If Tomcat, HikariCP or Commons DBCP are on the classpath one of them will be selected (in that order with Tomcat first).

... so, we can easily replace connection pool provider using this maven configuration (pom.xml):

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jdbc</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.apache.tomcat</groupId>
                <artifactId>tomcat-jdbc</artifactId>
            </exclusion>
        </exclusions>
    </dependency>       

    <dependency>
        <groupId>com.zaxxer</groupId>
        <artifactId>HikariCP</artifactId>
    </dependency>

The way I would do it is to create paragraph tags where you want your error messages with the same class and show them when the data is invalid. Here is my fiddle

if ($('#email').val() == '' || !$('#password').val() == '') {
    $('.loginError').show();
    return false;
}

I also added the paragraph tags below the email and password inputs

<p class="loginError" style="display:none;">please enter your email address or password.</p>

For version 5:

If you downloaded the free package from this site:

https://fontawesome.com/download

The fonts are in the all.css and all.min.css file.

So your reference will look something like this:

<link href="/MyProject/Content/fontawesome-free-5.10.1-web/css/all.min.css" rel="stylesheet">

The fontawesome.css file does not include the font reference.

In addition to @user26409021 's answer, If you have added a ItemFragment, The message in the ItemFragment is;

Activities containing this fragment MUST implement the {@link OnListFragmentInteractionListener} interface.

And You should add in your activity;

public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener, ItemFragment.OnListFragmentInteractionListener {

//the code is omitted

 public void onListFragmentInteraction(DummyContent.DummyItem uri){
    //you can leave it empty
}

Here the dummy item is what you have on the bottom of your ItemFragment

  func completeOffset(from date:Date) -> String? {

    let formatter = DateComponentsFormatter()
    formatter.unitsStyle = .brief

    return  formatter.string(from: Calendar.current.dateComponents([.year,.month,.day,.hour,.minute,.second], from: date, to: self))




}

if you need year month days and hours as string use this

var tomorrow = Calendar.current.date(byAdding: .day, value: 1, to: Date())!

let dc = tomorrow.completeOffset(from: Date())

func decorateText(sub:String, des:String)->NSAttributedString{
    let textAttributesOne = [NSAttributedStringKey.foregroundColor: UIColor.darkText, NSAttributedStringKey.font: UIFont(name: "PTSans-Bold", size: 17.0)!]
    let textAttributesTwo = [NSAttributedStringKey.foregroundColor: UIColor.black, NSAttributedStringKey.font: UIFont(name: "PTSans-Regular", size: 14.0)!]

    let textPartOne = NSMutableAttributedString(string: sub, attributes: textAttributesOne)
    let textPartTwo = NSMutableAttributedString(string: des, attributes: textAttributesTwo)

    let textCombination = NSMutableAttributedString()
    textCombination.append(textPartOne)
    textCombination.append(textPartTwo)
    return textCombination
}

//Implementation

cell.lblFrom.attributedText = decorateText(sub: sender!, des: " - \(convertDateFormatShort3(myDateString: datetime!))")

This is how i changed placeholder arrow color, the 2 classes are for dropdown open and dropdown closed, you need to change the #fff to the color you want:

.select2-container--default.select2-container--open .select2-selection--single .select2-selection__arrow b {
    border-color: transparent transparent #fff transparent !important;
  }
  .select2-container--default .select2-selection--single .select2-selection__arrow b {
    border-color: #fff transparent transparent transparent !important;
  }

In my case, my problem was environmental. Meaning, I did something wrong in my bash session. After attempting nearly everything in this thread, I opened a new bash session and everything was back to normal.

Both classes Rectangle and Ellipse need to override both of the abstract methods.

To work around this, you have 3 options:

• Add the two methods
• Make each class that extends Shape abstract

• Have a single method that does the function of the classes that will extend Shape, and override that method in Rectangle and Ellipse, for example:

  abstract class Shape {
      // ...
      void draw(Graphics g);
  }
  

And

    class Rectangle extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

Finally

    class Ellipse extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

And you can switch in between them, like so:

    Shape shape = new Ellipse();
    shape.draw(/* ... */);

    shape = new Rectangle();
    shape.draw(/* ... */);

Again, just an example.

Generally and simply it works like this:

<script>_x000D_
            $(document).ready(function () {_x000D_
                $('i').click(function () {_x000D_
                    $(this).toggleClass('fa-plus-square fa-minus-square');_x000D_
                });_x000D_
            });_x000D_
</script>

public static void main(String[] args) {
    System.out.println("is balanced : "+isBalanced("(){}[]<>"));
    System.out.println("is balanced : "+isBalanced("({})[]<>"));
    System.out.println("is balanced : "+isBalanced("({[]})<>"));
    System.out.println("is balanced : "+isBalanced("({[<>]})"));
    System.out.println("is balanced : "+isBalanced("({})[<>]"));


    System.out.println("is balanced : "+isBalanced("({[}])[<>]"));
    System.out.println("is balanced : "+isBalanced("([{})]"));
    System.out.println("is balanced : "+isBalanced("[({}])"));
    System.out.println("is balanced : "+isBalanced("[(<{>})]"));

    System.out.println("is balanced : "+isBalanced("["));
    System.out.println("is balanced : "+isBalanced("]"));

    System.out.println("is balanced : "+isBalanced("asdlsa"));
}

private static boolean isBalanced(String brackets){
    char[] bracketsArray = brackets.toCharArray();
    Stack<Character> stack = new Stack<Character>();
    Map<Character, Character> openingClosingMap = initOpeningClosingMap();

    for (char bracket : bracketsArray) {
        if(openingClosingMap.keySet().contains(bracket)){ 
            stack.push(bracket);
        }else if(openingClosingMap.values().contains(bracket)){
            if(stack.isEmpty() || openingClosingMap.get(stack.pop())!=bracket){
                return false;
            }
        }else{
            System.out.println("Only  < > ( ) { } [ ] brackets  are allowed .");
            return false;
        }
    }
    return stack.isEmpty();
}

private static Map<Character, Character> initOpeningClosingMap() {
    Map<Character, Character> openingClosingMap = new HashMap<Character, Character>();
    openingClosingMap.put(Character.valueOf('('), Character.valueOf(')'));
    openingClosingMap.put(Character.valueOf('{'), Character.valueOf('}'));
    openingClosingMap.put(Character.valueOf('['), Character.valueOf(']'));
    openingClosingMap.put(Character.valueOf('<'), Character.valueOf('>'));
    return openingClosingMap;
}

Simplifying and making readable. Using One Map only and minimum conditions to get desired result.

You've mixed tabs and spaces. __init__ is actually defined nested inside another method, so your class doesn't have its own __init__ method, and it inherits object.__init__ instead. Open your code in Notepad instead of whatever editor you're using, and you'll see your code as Python's tab-handling rules see it.

This is why you should never mix tabs and spaces. Stick to one or the other. Spaces are recommended.

npm install --save-dev @fortawesome/fontawesome-free

in index.js

import '@fortawesome/fontawesome-free/css/all.min.css';

then use icons like below :

import React, { Component } from "react";

class Like extends Component {
  state = {};
  render() {
    return <i className="fas fa-heart"></i>;
  }
}

export default Like;

.jumbotron {
background-color:black !important; 

}

Add this one line code in .css file, worked for me!

If you use Less you can directly use the following mixin:

.@{fa-css-prefix}-rotate-90  { .fa-icon-rotate(90deg, 1);  }

This is simple css for Sign Mark.

ul li:after{opacity: 1;content: '\2713';right: 20px;position: absolute;font-size: 20px;font-weight: bold;}

Update: Rather use flex.

If you want precision this is the way to go.

I used below layout and able to achieve custom layout in Navigation View.

<android.support.design.widget.NavigationView
        android:id="@+id/navi_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start|top"
        android:background="@color/navigation_view_bg_color"
        app:theme="@style/NavDrawerTextStyle">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <include layout="@layout/drawer_header" />

            <include layout="@layout/navigation_drawer_menu" />
        </LinearLayout>
</android.support.design.widget.NavigationView> 

1. Under Window Administrative Tools, run ODBC Data Sources (32-bit).

2. Under the Drivers tab, check you have the Microsoft Excel Driver (*.xls, *.xlsx etc...) - the file name is ACEODBC.DLL

3. If this is missing, you will need to install the Microsoft Access Database Engine 2016 Redistributable.

You'll find the installer here https://www.microsoft.com/en-us/download/details.aspx?id=54920

4. Your connection should be:

Set objConn1 = Server.CreateObject("ADODB.Connection") 
objConn1.Provider = "Microsoft.ACE.OLEDB.12.0"   
objConn1.ConnectionString = "Data Source=" & pPath & ";Extended Properties=""Excel 12.0 Xml;HDR=YES;IMEX=1""" 

var items = [
  {"id":"88","name":"Lets go testing"},
  {"id":"99","name":"Have fun boys and girls"},
  {"id":"108","name":"You are awesome!"}
];

If you are using jQuery, use jQuery.grep like this:

items = $.grep(items, function(item) { 
  return item.id !== '88';
});
// items => [{ id: "99" }, { id: "108" }]

Using ES5 Array.prototype.filter:

items = items.filter(function(item) { 
  return item.id !== '88'; 
});
// items => [{ id: "99" }, { id: "108" }]

You have to set the proper font path. e.g.

my-style.scss

$fa-font-path:"../node_modules/font-awesome/fonts";
@import "../node_modules/font-awesome/scss/font-awesome";
.icon-user {
  @extend .fa;
  @extend .fa-user;
}

The below should work

describe "#foo"
  it "should call 'bar' with appropriate arguments" do
     subject.stub(:bar)
     subject.foo
     expect(subject).to have_received(:bar).with("Invalid number of arguments")
  end
end

Documentation: https://github.com/rspec/rspec-mocks#expecting-arguments

var data = {
    "items": [{
        "id": 1,
        "category": "cat1"
    }, {
        "id": 2,
        "category": "cat2"
    }, {
        "id": 3,
        "category": "cat1"
    }]
};

var returnedData = $.grep(data.items, function (element, index) {
    return element.id == 1;
});


alert(returnedData[0].id + "  " + returnedData[0].category);

The returnedData is returning an array of objects, so you can access it by array index.

FluentWait throws a NoSuchElementException is case of the confusion

org.openqa.selenium.NoSuchElementException;     

with

java.util.NoSuchElementException

in

.ignoring(NoSuchElementException.class)

Another solution without you having to manually mess around with the Unicode characters can be found in Making Font Awesome awesome - Using icons without i-tags (disclaimer: I wrote this article).

In a nutshell, you can create a new class like this:

.icon::before {
    display: inline-block;
    margin-right: .5em;
    font: normal normal normal 14px/1 FontAwesome;
    font-size: inherit;
    text-rendering: auto;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    transform: translate(0, 0);
}

And then use it with any icon, for example:

<a class="icon fa-car" href="#">This is a link</a>

Here is a filter that will take a date string OR javascript Date() object. It uses Moment.js and can apply any Moment.js transform function, such as the popular 'fromNow'

angular.module('myModule').filter('moment', function () {
  return function (input, momentFn /*, param1, param2, ...param n */) {
    var args = Array.prototype.slice.call(arguments, 2),
        momentObj = moment(input);
    return momentObj[momentFn].apply(momentObj, args);
  };
});

So...

{{ anyDateObjectOrString | moment: 'format': 'MMM DD, YYYY' }}

would display Nov 11, 2014

{{ anyDateObjectOrString | moment: 'fromNow' }}

would display 10 minutes ago

If you need to call multiple moment functions, you can chain them. This converts to UTC and then formats...

{{ someDate | moment: 'utc' | moment: 'format': 'MMM DD, YYYY' }}

Use replace()

 s = s.replace("'", "\\'"); 

output:

You\'ll be totally awesome, I\'m really terrible

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

Well I'm not exactly sure why your code is not working because I usually follow a different approach when trying to accomplish something similar.

But your code is erroring out.. There seems to be an issue with the way you are using scale I got the jQuery to actually execute by changing your code to the following.

$(document).ready(function(){
    $('img').hover(function() {
        $(this).css("cursor", "pointer");
        $(this).toggle({
          effect: "scale",
          percent: "90%"
        },200);
    }, function() {
         $(this).toggle({
           effect: "scale",
           percent: "80%"
         },200);

    });
});  

But I have always done it by using CSS to setup my scaling and transition..

Here is an example, hopefully it helps.

$(document).ready(function(){
    $('#content').hover(function() {
        $("#content").addClass('transition');

    }, function() {
        $("#content").removeClass('transition');
    });
});

Do it with inline styles and script:

<div class="btn-group has-feedback has-clear">
    <input id="searchinput" type="search" class="form-control" style="width:200px;">
        <a 
id="searchclear" 
class="glyphicon glyphicon-remove-circle form-control-feedback form-control-clear" 
style="pointer-events:auto; text-decoration:none; cursor:pointer;"
onclick="$(this).prev('input').val('');return false;">
</a>
</div>

we must also need to add following in build.gradle(app)

compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'

whenever we are using new layouts or new design features. hope this helps you.

can you please try this: replace the case statement with the below one

Sum(CASE WHEN attempt.result = 0 THEN 0 ELSE 1 END) as Count,

Sounds like you've either hidden JavaScript logs or specified that you only want to see Errors or Warnings. Open Chrome's Developer Tools and go to the Console tab. At the bottom you want to ensure that JavaScript is ticked and also ensure that you have "All", "Logs" or "Debug" selected.

In the image above I have JavaScript, Network, Logging, CSS and Other ticked and "All" selected.

Another potential problem could be that your $(window).scroll() function isn't wrapped within a .ready() function (as documented here):

$(document).ready(function() {
    $(window).scroll(function() {
        ...
    });
});

When pasting your code into JSFiddle and giving some dummy content, your code works perfectly fine: JSFiddle demo.

Edit:

The question was edited. The new code given throws two errors:

Uncaught ReferenceError: fitHeight is not defined Uncaught TypeError: Cannot read property 'addEventListener' of null

Because of this, the code stops execution prior to reaching any console.log call.

To add a rounded border in any button the best way is to add the border-radius property. I belive this class is better because you can add-it at any button size. If you set the height and widht you will need to create a "rouding" class to each button size.

.btn-circle {_x000D_
  border-radius: 50%;_x000D_
}

<button class='btn-circle'>Click Me!</button>_x000D_
<button class='btn-circle'>?</button>

Since the question doesn't specify which shell, here's the eshell version based on the earlier answers. This goes in the eshell alias file, which might be in ~/.emacs.d/eshell/alias I've added the first part z https://github.com/rupa/z/ which let's you quickly cd to a directory, so that this can be run no matter what your current directory is.

Teocci solution is as simple as it can be, thus, no need to add any CSS, just add class="fas" for Font Awesome 5, since it adds proper CSS font declaration to the element.

Here's an example for search box within Bootstrap navbar, with search icon added to the both input-group and placeholder (for the sake of demontration, of course, no one would use both at the same time). Image: https://i.imgur.com/v4kQJ77.png "> Code:

<form class="form-inline my-2 my-lg-0">
    <div class="input-group mb-3">
        <div class="input-group-prepend">
            <span class="input-group-text"><i class="fas fa-search"></i></span>
        </div>
        <input type="text" class="form-control fas text-right" placeholder="&#xf002;" aria-label="Search string">
        <div class="input-group-append">
            <button class="btn btn-success input-group-text bg-success text-white border-0">Search</button>
        </div>
    </div>
</form>

Give a class to your cell containing the icon

<td class="icon"><i class="icon-ok"></i></td>

and then

.icon{
    text-align: center;
}

Well no, from an iOS developer prospective, there are two links that I know of that will open the Maps app on the iPhone

On iOS 5 and lower: http://maps.apple.com?q=xxxx

On iOS 6 and up: http://maps.google.com?q=xxxx

And that's only on Safari. Chrome will direct you to Google Maps webpage.

Other than that you'll need to use a URL scheme that basically beats the purpose because no android will know that protocol.

You might want to know, Why Safari opens the Maps app and Chrome directs me to a webpage?

Well, because safari is the build in browser made by apple and can detect the URL above. Chrome is "just another app" and must comply to the iOS Ecosystem. Therefor the only way for it to communicate with other apps is by using URL schemes.

The best way to remember this is that the order of for loop inside the list comprehension is based on the order in which they appear in traditional loop approach. Outer most loop comes first, and then the inner loops subsequently.

So, the equivalent list comprehension would be:

[entry for tag in tags for entry in entries if tag in entry]

In general, if-else statement comes before the first for loop, and if you have just an if statement, it will come at the end. For e.g, if you would like to add an empty list, if tag is not in entry, you would do it like this:

[entry if tag in entry else [] for tag in tags for entry in entries]

I have solved this problem by changing the gravity of the navigationview

android:layout_gravity

to end instead of start

<android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header"
        app:menu="@menu/activity_drawer" />

It worked for me.

For some reason the only way I was able to get my code to work is by switching couple of things. If nothing worked for you so far, please give a whirl to this:

$('body').popover({ 
    selector: '[data-toggle="popover"]', 
    trigger: 'hover',
    placement: 'right'
});

getFragmentManager().addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {

    @Override
    public void onBackStackChanged() {

        if(getFragmentManager().getBackStackEntryCount()==0) {
            onResume();
        }    
    }
});

Take a look also at etcd and Consul.

The spirit of Web font is to use cache as much as possible, therefore you should use CDN version between <head></head> instead of hosting yourself:

<link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.css" rel="stylesheet">

Also, make sure you loaded your CSS AFTER the above line, or your custom font CSS won't work.

Reference: Font Awesome Get Started

You can use

ng-bind-html https://docs.angularjs.org/api/ng/service/$sce

directive to bind html dynamically. However you have to get the data via $sce service.

Please see the live demo at http://plnkr.co/edit/k4s3Bx

var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope,$sce) {
    $scope.getHtml=function(){
   return $sce.trustAsHtml("<b>Hi Rupesh hi <u>dfdfdfdf</u>!</b>sdafsdfsdf<button>dfdfasdf</button>");
   }
});

  <body ng-controller="MainCtrl">
<span ng-bind-html="getHtml()"></span>
  </body>

UPDATE 2018 MAY:

Alternatively, you can embed Edge browser, but only targetting windows 10.

Here is the solution.

I had exactly the same problem when migrating from bootstrapv2 to v3.

If (like me) you migrated by replacing the old spanX with col-sm-X you also need to add col-X classes. col-X are the styles that are outside of any @media blocks so they work without media query support.

To fix the container width you can set it yourself outside of a @media block. Something like:

.container {
  max-width: @container-tablet;
}
@import "twitter-bootstrap/less/bootstrap";

.star-light::after {
    content: "\f005";
    font-family: "FontAwesome";
    font-size: 3.2rem;
    color: #fff;
    font-weight: 900;
    background-color: red;
}

the simplest solution to both horizontally and vertically centers the icon:

<div class="d-flex align-items-center justify-content-center">
    <i class="fas fa-crosshairs fa-lg"></i>
</div>

You can easily whip up your own function to do this using itertools:

from itertools import izip, islice, tee
s = 'spam and eggs'
N = 3
trigrams = izip(*(islice(seq, index, None) for index, seq in enumerate(tee(s, N))))
list(trigrams)
# [('s', 'p', 'a'), ('p', 'a', 'm'), ('a', 'm', ' '),
# ('m', ' ', 'a'), (' ', 'a', 'n'), ('a', 'n', 'd'),
# ('n', 'd', ' '), ('d', ' ', 'e'), (' ', 'e', 'g'),
# ('e', 'g', 'g'), ('g', 'g', 's')]

Just wrap the button label in an extra span and add class="align-middle" to both (the icon and the label). This will center your icon with text vertical.

<button id="edit-listing-form-house_Continue" 
    class="btn btn-large btn-primary"
    style=""
    value=""
    name="Continue"
    type="submit">
<span class="align-middle">Continue</span>
<i class="icon-ok align-middle" style="font-size:40px;"></i>

Use your developer's tool of choice and check if the tr, td or img has any padding or margins.

Well, this question was asked years ago. I think technology has changed quite a bit and browser compatibility is much better. You could use vertical-align but I would consider that some what less scaleable and less reusable. I would recommend a flexbox approach.

Here is the same example the original poster used but with flexbox. It styles a single element. If a button size changes for whatever reason, it will continue to be vertically and horizontally centered.

.button {
    border: 1px solid #ccc;
    height: 40px;
    margin: 60px;
    padding: 4px;
    display: flex;
    justify-content: space-around;
    align-items: center;
}

Example: JsFiddle

In latest 5.13 there's a difference. You do like always...

font-family: "Font Awesome 5 Free";
content: "\f107";

But there's a difference now... Instead of use font-weight: 500; You are following this:

font-family: "Font Awesome 5 Free";
font-weight: 900;
content: "\f107";

Why is that? I figure out by finding in in .fas class, so you can figure out an updated way by looking into .fas class so you're doing the same as it has to be. Figure out if there's a font-weight and font-family. Here you go guys. That's an update answer for 5.13.

Getting the ball rolling with this community wiki answer. Feel free to edit me with your improvements.

• ws WebSocket server and client for node.js. One of the fastest libraries if not the fastest one.

• websocket-node WebSocket server and client for node.js

• websocket-driver-node WebSocket server and client protocol parser node.js - used in faye-websocket-node

• faye-websocket-node WebSocket server and client for node.js - used in faye and sockjs

• socket.io WebSocket server and client for node.js + client for browsers + (v0 has newest to oldest fallbacks, v1 of Socket.io uses engine.io) + channels - used in stack.io. Client library tries to reconnect upon disconnection.

• sockjs WebSocket server and client for node.js and others + client for browsers + newest to oldest fallbacks

• faye WebSocket server and client for node.js and others + client for browsers + fallbacks + support for other server-side languages

• deepstream.io clusterable realtime server that handles WebSockets & TCP connections and provides data-sync, pub/sub and request/response

• socketcluster WebSocket server cluster which makes use of all CPU cores on your machine. For example, if you were to use an xlarge Amazon EC2 instance with 32 cores, you would be able to handle almost 32 times the traffic on a single instance.

• primus Provides a common API for most of the libraries above for easy switching + stability improvements for all of them.

When to use:

• use the basic WebSocket servers when you want to use the native WebSocket implementations on the clientside, beware of the browser incompatabilities

• use the fallback libraries when you care about browser fallbacks

• use the full featured libraries when you care about channels

• use primus when you have no idea about what to use, are not in the mood for rewriting your application when you need to switch frameworks because of changing project requirements or need additional connection stability.

Where to test:

Firecamp is a GUI testing environment for SocketIO, WS and all major real-time technology. Debug the real-time events while you're developing it.

You don't need to use complicated coding really!

Greyscale Hover:

-webkit-filter: grayscale(100%);

Greyscale "Hover-out":

-webkit-filter: grayscale(0%);

I simply made my css class have a separate hover class and added in the second greyscale. It's really simple if you really don't like complexity.

With plain Javascript, the simplest is:

document.onkeypress = function (e) {
    e = e || window.event;
    // use e.keyCode
};

But with this, you can only bind one handler for the event.

In addition, you could use the following to be able to potentially bind multiple handlers to the same event:

addEvent(document, "keypress", function (e) {
    e = e || window.event;
    // use e.keyCode
});

function addEvent(element, eventName, callback) {
    if (element.addEventListener) {
        element.addEventListener(eventName, callback, false);
    } else if (element.attachEvent) {
        element.attachEvent("on" + eventName, callback);
    } else {
        element["on" + eventName] = callback;
    }
}

In either case, keyCode isn't consistent across browsers, so there's more to check for and figure out. Notice the e = e || window.event - that's a normal problem with Internet Explorer, putting the event in window.event instead of passing it to the callback.

References:

• https://developer.mozilla.org/en-US/docs/DOM/Mozilla_event_reference/keypress
• https://developer.mozilla.org/en-US/docs/DOM/EventTarget.addEventListener

With jQuery:

$(document).on("keypress", function (e) {
    // use e.which
});

Reference:

• http://api.jquery.com/on/

Other than jQuery being a "large" library, jQuery really helps with inconsistencies between browsers, especially with window events...and that can't be denied. Hopefully it's obvious that the jQuery code I provided for your example is much more elegant and shorter, yet accomplishes what you want in a consistent way. You should be able to trust that e (the event) and e.which (the key code, for knowing which key was pressed) are accurate. In plain Javascript, it's a little harder to know unless you do everything that the jQuery library internally does.

Note there is a keydown event, that is different than keypress. You can learn more about them here: onKeyPress Vs. onKeyUp and onKeyDown

As for suggesting what to use, I would definitely suggest using jQuery if you're up for learning the framework. At the same time, I would say that you should learn Javascript's syntax, methods, features, and how to interact with the DOM. Once you understand how it works and what's happening, you should be more comfortable working with jQuery. To me, jQuery makes things more consistent and is more concise. In the end, it's Javascript, and wraps the language.

Another example of jQuery being very useful is with AJAX. Browsers are inconsistent with how AJAX requests are handled, so jQuery abstracts that so you don't have to worry.

Here's something that might help decide:

• http://www.jscripters.com/jquery-disadvantages-and-advantages/

Just enable parsing of the autoexec.bat in the registry, using these instructions.

:: works only on windows vista and earlier 
Run REGEDT32.EXE.
Modify the following value within HKEY_CURRENT_USER: 

Software\Microsoft\Windows NT\CurrentVersion\Winlogon\ParseAutoexec 

1 = autoexec.bat is parsed
0 = autoexec.bat is not parsed

Change your input to a button element and you can use the Font Awesome classes on it. The alignment of the glyph isn't great in the demo, but you get the idea:

The advantage here is that the form is still fully functional without having to add event handlers for elements that aren't buttons but look like one.

That method will not work. The <title> only supports plain text. You will need to create an .ico image with the filename of favicon.ico and save it into the root folder of your site (where your default page is).

Alternatively, you can save the icon where ever you wish and call it whatever you want, but simply insert the following code into the <head> section of your HTML and reference your icon:

<link rel="shortcut icon" href="your_image_path_and_name.ico" />

You can use Photoshop (with a plug in) or GIMP (free) to create an .ico file, or you can just use IcoFX, which is my personal favourite as it is really easy to use and does a great job (you can get an older version of the software for free from download.com).

Update 1: You can also use a number of online tools to create favicons such as ConvertIcon, which I've used successfully. There are other free online tools available now too, which do the same (accessible by a simple Google search), but also generate other icons such as the Windows 8/10 Start Menu icons and iOS App Icons.

Update 2: You can also use .png images as icons providing IE11 is the only version of IE you need to support. You just need to reference them using the HTML code above. Note that IE10 and older still require .ico files.

Update 3: You can now use Emoji characters in the title field. On Windows 10, it should generally fall back and use the Segoe UI Emoji font and display nicely, however you'll need to test and see how other systems support and display your chosen emoji, as not all devices may have the same Emoji available.

try this

   SELECT group_name, employees, surveys, COUNT( surveys ) AS test1, 
        concat(round(( surveys/employees * 100 ),2),'%') AS percentage
    FROM a_test
    GROUP BY employees

DEMO HERE

They all attach this into function (or object) and the difference is in the function invocation (see below).

call attaches this into function and executes the function immediately:

var person = {  
  name: "James Smith",
  hello: function(thing) {
    console.log(this.name + " says hello " + thing);
  }
}

person.hello("world");  // output: "James Smith says hello world"
person.hello.call({ name: "Jim Smith" }, "world"); // output: "Jim Smith says hello world"

bind attaches this into function and it needs to be invoked separately like this:

var person = {  
  name: "James Smith",
  hello: function(thing) {
    console.log(this.name + " says hello " + thing);
  }
}

person.hello("world");  // output: "James Smith says hello world"
var helloFunc = person.hello.bind({ name: "Jim Smith" });
helloFunc("world");  // output: Jim Smith says hello world"

or like this:

...    
var helloFunc = person.hello.bind({ name: "Jim Smith" }, "world");
helloFunc();  // output: Jim Smith says hello world"

apply is similar to call except that it takes an array-like object instead of listing the arguments out one at a time:

function personContainer() {
  var person = {  
     name: "James Smith",
     hello: function() {
       console.log(this.name + " says hello " + arguments[1]);
     }
  }
  person.hello.apply(person, arguments);
}
personContainer("world", "mars"); // output: "James Smith says hello mars", note: arguments[0] = "world" , arguments[1] = "mars"                                     

As all answers are great but I didn't want to use a library and each solution with just one line java code made my Activities and Fragments very messy. So I over wrote the TextView class as follows:

public class FontAwesomeTextView extends TextView {
private static final String TAG = "TextViewFontAwesome";
public FontAwesomeTextView(Context context) {
    super(context);
    init();
}

public FontAwesomeTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
    init();
}

public FontAwesomeTextView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    init();
}

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
public FontAwesomeTextView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
    super(context, attrs, defStyleAttr, defStyleRes);
    init();
}

private void setCustomFont(Context ctx, AttributeSet attrs) {
    TypedArray a = ctx.obtainStyledAttributes(attrs, R.styleable.TextViewPlus);
    String customFont = a.getString(R.styleable.TextViewPlus_customFont);
    setCustomFont(ctx, customFont);
    a.recycle();
}

private void init() {
    if (!isInEditMode()) {
        Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "fontawesome-webfont.ttf");
        setTypeface(tf);
    }
}

public boolean setCustomFont(Context ctx, String asset) {
    Typeface typeface = null;
    try {
        typeface = Typeface.createFromAsset(ctx.getAssets(), asset);
    } catch (Exception e) {
        Log.e(TAG, "Unable to load typeface: "+e.getMessage());
        return false;
    }

    setTypeface(typeface);
    return true;
}
}

what you should do is copy the font ttf file into assets folder .And use this cheat sheet for finding each icons string.

hope this helps.

I don't like it either.

So use javascript:

Public Function GetJavaScriptResult(doc as HTMLDocument, jsString As String) As String

    Dim el As IHTMLElement
    Dim nd As HTMLDOMTextNode

    Set el = doc.createElement("INPUT")
    Do
        el.ID = GenerateRandomAlphaString(100)
    Loop Until Document.getElementById(el.ID) Is Nothing
    el.Style.display = "none"
    Set nd = Document.appendChild(el)

    doc.parentWindow.ExecScript "document.getElementById('" & el.ID & "').value = " & jsString

    GetJavaScriptResult = Document.getElementById(el.ID).Value

    Document.removeChild nd

End Function


Function GenerateRandomAlphaString(Length As Long) As String

    Dim i As Long
    Dim Result As String

    Randomize Timer

    For i = 1 To Length
        Result = Result & Chr(Int(Rnd(Timer) * 26 + 65 + Round(Rnd(Timer)) * 32))
    Next i

    GenerateRandomAlphaString = Result

End Function

Let me know if you have any problems with this; I've changed the context from a method to a function.

By the way, what version of IE are you using? I suspect you're on < IE8. If you upgrade to IE8 I presume it'll update shdocvw.dll to ieframe.dll and you will be able to use document.querySelector/All.

Edit

Comment response which isn't really a comment: Basically the way to do this in VBA is to traverse the child nodes. The problem is you don't get the correct return types. You could fix this by making your own classes that (separately) implement IHTMLElement and IHTMLElementCollection; but that's WAY too much of a pain for me to do it without getting paid :). If you're determined, go and read up on the Implements keyword for VB6/VBA.

Public Function getSubElementsByTagName(el As IHTMLElement, tagname As String) As Collection

    Dim descendants As New Collection
    Dim results As New Collection
    Dim i As Long

    getDescendants el, descendants

    For i = 1 To descendants.Count
        If descendants(i).tagname = tagname Then
            results.Add descendants(i)
        End If
    Next i

    getSubElementsByTagName = results

End Function

Public Function getDescendants(nd As IHTMLElement, ByRef descendants As Collection)
    Dim i As Long
    descendants.Add nd
    For i = 1 To nd.Children.Length
        getDescendants nd.Children.Item(i), descendants
    Next i
End Function

A lazy way to do this is with the UTF-8 entity code for a half circle \25E0 (aka ◠), which looks like ? and then keyframe animate it. It's a simple as:

.busy
{
animation: spin 1s infinite linear;
display:inline-block;
font-weight: bold;
font-family: sans-serif;
font-size: 35px;
font-style:normal;
color:#555;
}

.busy::before
{
content:"\25E0";
}

@keyframes spin
{
0% {transform: rotate(0deg);}
100% {transform: rotate(359deg);}
}

<i class="busy"></i>

We need to define what is a web service before telling what are the difference between the SOAP and WSDL where the two (SOAP and WSDL) are components of a web service

Most applications are developed to interact with users, the user enters or searches for data through an interface and the application then responds to the user's input.

A Web service does more or less the same thing except that a Web service application communicates only from machine to machine or application to application. There is often no direct user interaction.

A Web service basically is a collection of open protocols that is used to exchange data between applications. The use of open protocols enables Web services to be platform independent. Software that are written in different programming languages and that run on different platforms can use Web services to exchange data over computer networks such as the Internet. In other words, Windows applications can talk to PHP, Java and Perl applications and many others, which in normal circumstances would not be possible.

How Do Web Services Work?

Because different applications are written in different programming languages, they often cannot communicate with each other. A Web service enables this communication by using a combination of open protocols and standards, chiefly XML, SOAP and WSDL. A Web service uses XML to tag data, SOAP to transfer a message and finally WSDL to describe the availability of services. Let's take a look at these three main components of a Web service application.

Simple Object Access Protocol (SOAP)

The Simple Object Access Protocol or SOAP is a protocol for sending and receiving messages between applications without confronting interoperability issues (interoperability meaning the platform that a Web service is running on becomes irrelevant). Another protocol that has a similar function is HTTP. It is used to access Web pages or to surf the Net. HTTP ensures that you do not have to worry about what kind of Web server -- whether Apache or IIS or any other -- serves you the pages you are viewing or whether the pages you view were created in ASP.NET or HTML.

Because SOAP is used both for requesting and responding, its contents vary slightly depending on its purpose.

Below is an example of a SOAP request and response message

SOAP Request:

POST /InStock HTTP/1.1 
Host: www.bookshop.org 
Content-Type: application/soap+xml; charset=utf-8 
Content-Length: nnn 
<?xml version="1.0"?> 
<soap:Envelope 
xmlns:soap="http://www.w3.org/2001/12/soap-envelope" 
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding"> 
<soap:Body xmlns:m="http://www.bookshop.org/prices"> 
    <m:GetBookPrice> 
    <m:BookName>The Fleamarket</m:BookName> 
    </m:GetBookPrice> 
</soap:Body> 
</soap:Envelope>

SOAP Response:

POST /InStock HTTP/1.1 
Host: www.bookshop.org 
Content-Type: application/soap+xml; charset=utf-8 
Content-Length: nnn 
<?xml version="1.0"?> 
<soap:Envelope 
xmlns:soap="http://www.w3.org/2001/12/soap-envelope" 
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding"> 
<soap:Body xmlns:m="http://www.bookshop.org/prices"> 
    <m:GetBookPriceResponse> 
    <m: Price>10.95</m: Price> 
    </m:GetBookPriceResponse> 
</soap:Body> 
</soap:Envelope> 

Although both messages look the same, they carry out different methods. For instance looking at the above examples you can see that the requesting message uses the GetBookPrice method to get the book price. The response is carried out by the GetBookPriceResponse method, which is going to be the message that you as the "requestor" will see. You can also see that the messages are composed using XML.

Web Services Description Language or WSDL

WSDL is a document that describes a Web service and also tells you how to access and use its methods.

WSDL takes care of how do you know what methods are available in a Web service that you stumble across on the Internet.

Take a look at a sample WSDL file:

<?xml version="1.0" encoding="UTF-8"?> 
<definitions  name ="DayOfWeek"  
  targetNamespace="http://www.roguewave.com/soapworx/examples/DayOfWeek.wsdl" 
  xmlns:tns="http://www.roguewave.com/soapworx/examples/DayOfWeek.wsdl" 
  xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"  
  xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
  xmlns="http://schemas.xmlsoap.org/wsdl/">  
  <message name="DayOfWeekInput"> 
    <part name="date" type="xsd:date"/> 
  </message> 
  <message name="DayOfWeekResponse"> 
    <part name="dayOfWeek" type="xsd:string"/> 
  </message> 
  <portType name="DayOfWeekPortType"> 
    <operation name="GetDayOfWeek"> 
      <input message="tns:DayOfWeekInput"/> 
      <output message="tns:DayOfWeekResponse"/> 
    </operation> 
  </portType> 
  <binding name="DayOfWeekBinding" type="tns:DayOfWeekPortType"> 
    <soap:binding style="document"  
      transport="http://schemas.xmlsoap.org/soap/http"/> 
    <operation name="GetDayOfWeek"> 
      <soap:operation soapAction="getdayofweek"/> 
      <input> 
        <soap:body use="encoded"  
          namespace="http://www.roguewave.com/soapworx/examples"  
          encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> 
      </input> 
      <output> 
        <soap:body use="encoded"  
          namespace="http://www.roguewave.com/soapworx/examples"   
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> 
      </output> 
    </operation> 
  </binding> 
  <service name="DayOfWeekService" > 
    <documentation> 
      Returns the day-of-week name for a given date 
    </documentation> 
    <port name="DayOfWeekPort" binding="tns:DayOfWeekBinding"> 
      <soap:address location="http://localhost:8090/dayofweek/DayOfWeek"/> 
    </port> 
  </service> 
</definitions> 

The main things to remember about a WSDL file are that it provides you with:

If you don't want to alter the CSS file, this is what works for me. In HTML, add style with color:

<i class="fa fa-cog" style="color:#fff;"></i>

Open your font-awesome.css theres code like :

@font-face {
  font-family: 'FontAwesome';
  src: url('../fonts/fontawesome-webfont.eot?v=4.5.0');
  src: url('../fonts/fontawesome-webfont.eot?#iefix&v=4.5.0') format('embedded-opentype'), url('../fonts/fontawesome-webfont.woff2?v=4.5.0') format('woff2'), url('../fonts/fontawesome-webfont.woff?v=4.5.0') format('woff'), url('../fonts/fontawesome-webfont.ttf?v=4.5.0') format('truetype'), url('../fonts/fontawesome-webfont.svg?v=4.5.0#fontawesomeregular') format('svg');
  font-weight: normal;
  font-style: normal;
}

you must have folder like :

font awesome -> css
             -> fonts

or the easiest way :

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css">

At first link fontwaesome CSS file in your HTML file then create an after or before pseudo class like "font-family: "FontAwesome"; content: "\f101";" then save. I hope this work good.

I think all you need to display the data on an HTML page is JSON.stringify.

For example, if your JSON is stored like this:

var jsonVar = {
        text: "example",
        number: 1
    };

Then you need only do this to convert it to a string:

var jsonStr = JSON.stringify(jsonVar);

And then you can insert into your HTML directly, for example:

document.body.innerHTML = jsonStr;

Of course you will probably want to replace body with some other element via getElementById.

As for the CSS part of your question, you could use RegExp to manipulate the stringified object before you put it into the DOM. For example, this code (also on JSFiddle for demonstration purposes) should take care of indenting of curly braces.

var jsonVar = {
        text: "example",
        number: 1,
        obj: {
            "more text": "another example"
        },
        obj2: {
             "yet more text": "yet another example"
        }
    }, // THE RAW OBJECT
    jsonStr = JSON.stringify(jsonVar),  // THE OBJECT STRINGIFIED
    regeStr = '', // A EMPTY STRING TO EVENTUALLY HOLD THE FORMATTED STRINGIFIED OBJECT
    f = {
            brace: 0
        }; // AN OBJECT FOR TRACKING INCREMENTS/DECREMENTS,
           // IN PARTICULAR CURLY BRACES (OTHER PROPERTIES COULD BE ADDED)

regeStr = jsonStr.replace(/({|}[,]*|[^{}:]+:[^{}:,]*[,{]*)/g, function (m, p1) {
var rtnFn = function() {
        return '<div style="text-indent: ' + (f['brace'] * 20) + 'px;">' + p1 + '</div>';
    },
    rtnStr = 0;
    if (p1.lastIndexOf('{') === (p1.length - 1)) {
        rtnStr = rtnFn();
        f['brace'] += 1;
    } else if (p1.indexOf('}') === 0) {
         f['brace'] -= 1;
        rtnStr = rtnFn();
    } else {
        rtnStr = rtnFn();
    }
    return rtnStr;
});

document.body.innerHTML += regeStr; // appends the result to the body of the HTML document

This code simply looks for sections of the object within the string and separates them into divs (though you could change the HTML part of that). Every time it encounters a curly brace, however, it increments or decrements the indentation depending on whether it's an opening brace or a closing (behaviour similar to the space argument of 'JSON.stringify'). But you could this as a basis for different types of formatting.

Well,

If you mark all involved classes as serializable you can :

public static List<T> CloneList<T>(List<T> oldList)  
{  
BinaryFormatter formatter = new BinaryFormatter();  
MemoryStream stream = new MemoryStream();  
formatter.Serialize(stream, oldList);  
stream.Position = 0;  
return (List<T>)formatter.Deserialize(stream);      
}

Just use the vi + filename command.

Example:

vi stylesheet.css

This will open vi editor with the file content.

To start editing, press I

this is an another way:

<html>
<head>
    <title>Echo</title>
    <style type="text/css">
    #result{
        border: 1px solid #000000;
        min-height: 250px;
        max-height: 100%;
        padding: 5px;
        font-family: sans-serif;
        font-size: 12px;
    }
    </style>
    <script type="text/javascript" lang="ja">
    function start(){
        function echo(text){
            lastResultAreaText = document.getElementById('result').innerHTML;
            resultArea = document.getElementById('result');
            if(lastResultAreaText==""){
                resultArea.innerHTML=text;
            }
            else{
                resultArea.innerHTML=lastResultAreaText+"</br>"+text;
            }
        }

        echo("Hello World!");
        }
    </script>
</head>
<body onload="start()">
<pre id="result"></pre> 
</body>

I'd like to provide an alternate, easier solution that is specific to FontAwesome. If you're using a different iconic font, JOPLOmacedo's answer is still perfectly fine for use.

FontAwesome now handles list styles internally with CSS classes.

Here's the official example:

<ul class="fa-ul">
  <li><span class="fa-li"><i class="fas fa-check-square"></i></span>List icons can</li>
  <li><span class="fa-li"><i class="fas fa-check-square"></i></span>be used to</li>
  <li><span class="fa-li"><i class="fas fa-spinner fa-pulse"></i></span>replace bullets</li>
  <li><span class="fa-li"><i class="far fa-square"></i></span>in lists</li>
</ul>

After generation of woff files, you have to define font-family, which can be used later in all your css styles. Below is the code to define font families (for normal, bold, bold-italic, italic) typefaces. It is assumed, that there are 4 *.woff files (for mentioned typefaces), placed in fonts subdirectory.

In CSS code:

@font-face {
    font-family: "myfont";
    src: url("fonts/awesome-font.woff") format('woff');
}

@font-face {
    font-family: "myfont";
    src: url("fonts/awesome-font-bold.woff") format('woff');
    font-weight: bold;
}

@font-face {
    font-family: "myfont";
    src: url("fonts/awesome-font-boldoblique.woff") format('woff');
    font-weight: bold;
    font-style: italic;
}

@font-face {
    font-family: "myfont";
    src: url("fonts/awesome-font-oblique.woff") format('woff');
    font-style: italic;
}

After having that definitions, you can just write, for example,

In HTML code:

<div class="mydiv">
    <b>this will be written with awesome-font-bold.woff</b>
    <br/>
    <b><i>this will be written with awesome-font-boldoblique.woff</i></b>
    <br/>
    <i>this will be written with awesome-font-oblique.woff</i>
    <br/>
    this will be written with awesome-font.woff
</div>

In CSS code:

.mydiv {
    font-family: myfont
}

The good tool for generation woff files, which can be included in CSS stylesheets is located here. Not all woff files work correctly under latest Firefox versions, and this generator produces 'correct' fonts.

Try this instead:

$journalName = preg_replace('/\s+/', '_', $journalName);

Explanation: you are most likely seeing whitespace, not just plain spaces (there is a difference).

There's an example of how to use Font Awesome alongside an unordered list on their examples page.

<ul class="icons">
  <li><i class="icon-ok"></i> Lists</li>
  <li><i class="icon-ok"></i> Buttons</li>
  <li><i class="icon-ok"></i> Button groups</li>
  <li><i class="icon-ok"></i> Navigation</li>
  <li><i class="icon-ok"></i> Prepended form inputs</li>
</ul>

If you can't find it working after trying this code then you're not including the library correctly. According to their website, you should include the libraries as such:

<link rel="stylesheet" href="../css/bootstrap.css">
<link rel="stylesheet" href="../css/font-awesome.css">

Also check out the whimsical Chris Coyier's post on icon fonts on his website CSS Tricks.

Here's a screencast by him as well talking about how to create your own icon font-face.

It is not that complicated actually. Relevant Qt widgets are in matplotlib.backends.backend_qt4agg. FigureCanvasQTAgg and NavigationToolbar2QT are usually what you need. These are regular Qt widgets. You treat them as any other widget. Below is a very simple example with a Figure, Navigation and a single button that draws some random data. I've added comments to explain things.

import sys
from PyQt4 import QtGui

from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt4agg import NavigationToolbar2QT as NavigationToolbar
from matplotlib.figure import Figure

import random

class Window(QtGui.QDialog):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)

        # a figure instance to plot on
        self.figure = Figure()

        # this is the Canvas Widget that displays the `figure`
        # it takes the `figure` instance as a parameter to __init__
        self.canvas = FigureCanvas(self.figure)

        # this is the Navigation widget
        # it takes the Canvas widget and a parent
        self.toolbar = NavigationToolbar(self.canvas, self)

        # Just some button connected to `plot` method
        self.button = QtGui.QPushButton('Plot')
        self.button.clicked.connect(self.plot)

        # set the layout
        layout = QtGui.QVBoxLayout()
        layout.addWidget(self.toolbar)
        layout.addWidget(self.canvas)
        layout.addWidget(self.button)

• NavigationToolbar2QTAgg changed with NavigationToolbar2QT
• Directly import Figure instead of pyplot
• Replace deprecated ax.hold(False) with ax.clear()

I had the same problem when I tried to use the icons directly from BootstrapCDN (the easiest way). Then I downloaded the CSS file and copied it to my site's CSS folder the CSS file (Described under the 'easy way' in font awesome documentation), and everything started working as they should.

I found another strange reason and i thought maybe another developer confused as me. I did run install.bat that created to install my service in developer Command Prompt of VS2010 but my service generated in VS2012. it was going to this error and drives me to crazy but i try VS2012 Developer Command Prompt tools and everything gone to be OK. I don't no why but my problem was solved. so you can test it and if anyone know reason of that please share with us. Thanks.

If you want to use a javascript/node.js tool, take a look at markdown-toc.

@keithwyland answer is great. Here's a SCSS mixin:

@mixin font-awesome($content){
    font-family: FontAwesome;
    font-weight: normal;
    font-style: normal;
    display: inline-block;
    text-decoration: inherit;
    content: $content;
}

Usage:

@include font-awesome("\f054");

HTML

Since <input> element displays only value of value attribute, we have to manipulate only it:

<input type="submit" class="btn fa-input" value="&#xf043; Input">

I'm using  entity here, which corresponds to the U+F043, the Font Awesome's 'tint' symbol.

CSS

Then we have to style it to use the font:

.fa-input {
  font-family: FontAwesome, 'Helvetica Neue', Helvetica, Arial, sans-serif;
}

Which will give us the tint symbol in Font Awesome and the other text in the appropriate font.

However, this control will not be pixel-perfect, so you might have to tweak it by yourself.

Similar approach to @Samuel-bergström:

• Download Fontawesome SVG https://github.com/FortAwesome/Font-Awesome/blob/master/src/assets/font-awesome/fonts/fontawesome-webfont.svg
• Download FontForge http://fontforge.github.io/en-US/downloads/
• Download Inkscape
• Open Inskscape and create a single layer shape as your new font icon
• Save SVG file, Close Inkscape
• Open FontForge (If you have multiple monitors, use Windows-LeftArrow, to reposition as they have strange SWING java windows that go off monitor, and have modal problems with popups - I had to check my task bar for some)
• File | Open fontawesome-webfont.svg
• File | Import
• Scroll to the bottom, Right Click on Icon | Glyph Info
• Update Glyph Name to uniFXXX (XXX is something like 501, a higher number than the highest Unicode used in v4.5 of FontAwesome)
• Unicode Vlaue U+fXXX
• Click OK
• File | Save
• File | Generate Fonts ...
• Close FontForge
• Open your web project
• Copy your font files to the (in my project) "\Content\fonts\" folder.
• Edit "\Content\styles\fa\path.less" to be like:

@font-face {_x000D_
      font-family: 'FontAwesome';_x000D_
      //src: url('@{fa-font-path}/fontawesome-webfont.eot?v=@{fa-version}');_x000D_
      src: _x000D_
     //url('@{fa-font-path}/fontawesome-webfont.eot?#iefix&v=@{fa-version}') format('embedded-opentype'),_x000D_
        //url('@{fa-font-path}/fontawesome-webfont.woff2?v=@{fa-version}') format('woff2'),_x000D_
        url('@{fa-font-path}/fontawesomeregular.woff?v=@{fa-version}') format('woff'),_x000D_
        url('@{fa-font-path}/fontawesomeregular.ttf?v=@{fa-version}') format('truetype'),_x000D_
        url('@{fa-font-path}/fontawesomeregular.svg?v=@{fa-version}#fontawesomeregular') format('svg');_x000D_
    //  src: url('@{fa-font-path}/FontAwesome.otf') format('opentype'); // used when developing fonts_x000D_
      font-weight: normal;_x000D_
      font-style: normal;_x000D_
    }

I know it may be 'controversial' to comment out other file types, but happy to hear how to generate .eot or .otf files in the comments.

• and finally, as Samuel mentions, update your CSS/LESS with:

  .fa-XXX:before { content: "\f501"; }

I know this is an old question but the most up to date answer is to use the Android Support Design library that will make your life easy.

I have set a php code which can help in case you want to access Instagram images without api on basis of hashtag

Php Code for Instagram hashtag images

I maybe discovered a better way for not forcing the user to right click and "save image as". Live draw the canvas base64 code into the href of the link and modify it so the download will start automatically. I don't know if it's universally browser compatible, but it should work with the main/new browsers.

var canvas = document.getElementById('your-canvas');
    if (canvas.getContext) {
        var C = canvas.getContext('2d');
    }

$('#your-canvas').mousedown(function(event) {
    // feel free to choose your event ;) 

    // just for example
    // var OFFSET = $(this).offset();
    // var x = event.pageX - OFFSET.left;
    // var y = event.pageY - OFFSET.top;

    // standard data to url
    var imgdata = canvas.toDataURL('image/png');
    // modify the dataUrl so the browser starts downloading it instead of just showing it
    var newdata = imgdata.replace(/^data:image\/png/,'data:application/octet-stream');
    // give the link the values it needs
    $('a.linkwithnewattr').attr('download','your_pic_name.png').attr('href',newdata);

});

You can wrap the <a> around anything you want.

https://github.com/dualface/cocos2d-x-extensions/blob/master/TODO.tasks , he is developing nice features on cocos2d-x

Basically, the buttons in Twitter Bootstrap are controlled in CSS by ".btn{}". What you have to do is go to the CSS file and find where it says "btn" and change the color settings. However, it's not as simple as just doing that since you also have to change what color the button changes into when you highlight it, etc. To do THAT, you have to look for other tags in CSS like ".btn:hover{}", etc.

Changing it requires changing of the CSS. Here is a quick link to that file:

I put the IPython notebook in the same folder with the image. I use Windows. The image name is "phuong huong xac dinh.PNG".

Postgres 9.2

I quote Andrew Dunstan on the pgsql-hackers list:

At some stage there will possibly be some json-processing (as opposed to json-producing) functions, but not in 9.2.

Doesn't prevent him from providing an example implementation in PLV8 that should solve your problem.

Postgres 9.3

Offers an arsenal of new functions and operators to add "json-processing".

• The manual on new JSON functionality.
• The Postgres Wiki on new features in pg 9.3.
• @Will posted a link to a blog demonstrating the new operators in a comments below.

The answer to the original question in Postgres 9.3:

SELECT *
FROM   json_array_elements(
  '[{"name": "Toby", "occupation": "Software Engineer"},
    {"name": "Zaphod", "occupation": "Galactic President"} ]'
  ) AS elem
WHERE elem->>'name' = 'Toby';

Advanced example:

• Query combinations with nested array of records in JSON datatype

For bigger tables you may want to add an expression index to increase performance:

• Index for finding an element in a JSON array

Postgres 9.4

Adds jsonb (b for "binary", values are stored as native Postgres types) and yet more functionality for both types. In addition to expression indexes mentioned above, jsonb also supports GIN, btree and hash indexes, GIN being the most potent of these.

• The manual on json and jsonb data types and functions.
• The Postgres Wiki on JSONB in pg 9.4

The manual goes as far as suggesting:

In general, most applications should prefer to store JSON data as jsonb, unless there are quite specialized needs, such as legacy assumptions about ordering of object keys.

Bold emphasis mine.

Performance benefits from general improvements to GIN indexes.

Postgres 9.5

Complete jsonb functions and operators. Add more functions to manipulate jsonb in place and for display.

• Major good news in the release notes of Postgres 9.5.

They have wrapped most stuff need to solve your problem, one of the tests looks like this:

String filename = CSSURLEmbedderTest.class.getResource("folder.png").getPath().replace("%20", " ");
String code = "background: url(folder.png);";

StringWriter writer = new StringWriter();
embedder = new CSSURLEmbedder(new StringReader(code), true);
embedder.embedImages(writer, filename.substring(0, filename.lastIndexOf("/")+1));

String result = writer.toString();
assertEquals("background: url(" + folderDataURI + ");", result);

Thank you for pointing right direction in domain name validation solutions in other answers. Domain names could be validated in various ways.

If you need to validate IDN domain in it's human readable form, regex \p{L} will help. This allows to match any character in any language.

Note that last part might contain hyphens too! As punycode encoded Chineese names might have unicode characters in tld.

I've came to solution which will match for example:

• google.com
• maselkowski.pl
• maselkowski.pl
• m.maselkowski.pl
• www.maselkowski.pl.com
• xn--masekowski-d0b.pl
• ??????????.??
• xn--fiqa61au8b7zsevnm8ak20mc4a87e.xn--fiqs8s

Regex is:

^[0-9\p{L}][0-9\p{L}-\.]{1,61}[0-9\p{L}]\.[0-9\p{L}][\p{L}-]*[0-9\p{L}]+$

Check and tune here

NOTE: This regexp is quite permissive, as is current domain names allowed character set.

UPDATE: Even more simplified, as a-aA-Z\p{L} is same as just \p{L}

NOTE2: The only problem is that it will match domains with double dots in it... , like maselk..owski.pl. If anyone know how to fix this please improve.

The RFC for the HTTP Header Field X-Frame-Options states that the "ALLOW-FROM" field in the X-Frame-Options header value can only contain one domain. Multiple domains are not allowed.

The RFC suggests a work around for this problem. The solution is to specify the domain name as a url parameter in the iframe src url. The server that hosts the iframe src url can then check the domain name given in the url parameters. If the domain name matches a list of valid domain names, then the server can send the X-Frame-Options header with the value: "ALLOW-FROM domain-name", where domain name is the name of the domain that is trying to embed the remote content. If the domain name is not given or is not valid, then the X-Frame-Options header can be sent with the value: "deny".

Looking at shape

Take a gander at the shape of the red portion of the can/bottle. Notice how the can tapers off slightly at the very top whereas the bottle label is straight. You can distinguish between these two by comparing the width of the red portion across the length of it.

Looking at highlights

One way to distinguish between bottles and cans is the material. A bottle is made of plastic whereas a can is made of aluminum metal. In sufficiently well-lit situations, looking at the specularity would be one way of telling a bottle label from a can label.

As far as I can tell, that is how a human would tell the difference between the two types of labels. If the lighting conditions are poor, there is bound to be some uncertainty in distinguishing the two anyways. In that case, you would have to be able to detect the presence of the transparent/translucent bottle itself.

Reference the DLL´s to your Resources and and use the AssemblyResolve-Event to return the Resource-DLL.

public partial class App : Application
{
    public App()
    {
        AppDomain.CurrentDomain.AssemblyResolve += (sender, args) =>
        {

            Assembly thisAssembly = Assembly.GetExecutingAssembly();

            //Get the Name of the AssemblyFile
            var name = args.Name.Substring(0, args.Name.IndexOf(',')) + ".dll";

            //Load form Embedded Resources - This Function is not called if the Assembly is in the Application Folder
            var resources = thisAssembly.GetManifestResourceNames().Where(s => s.EndsWith(name));
            if (resources.Count() > 0)
            {
                var resourceName = resources.First();
                using (Stream stream = thisAssembly.GetManifestResourceStream(resourceName))
                {
                    if (stream == null) return null;
                    var block = new byte[stream.Length];
                    stream.Read(block, 0, block.Length);
                    return Assembly.Load(block);
                }
            }
            return null;
        };
    }
}

You should be using a Property:

Private _myValue As String
Public Property MyValue As String
    Get
        Return _myValue
    End Get
    Set(value As String)
        _myValue = value
     End Set
End Property

Then use it like so:

MyValue = "Hello"
Console.write(MyValue)

As it was mentioned above CasperJS is the best tool to fill and send forms. Simplest possible example of how to fill & submit form using fill() function:

casper.start("http://example.com/login", function() {
//searches and fills the form with id="loginForm"
  this.fill('form#loginForm', {
    'login':    'admin',
    'password':    '12345678'
   }, true);
  this.evaluate(function(){
    //trigger click event on submit button
    document.querySelector('input[type="submit"]').click();
  });
});

Probably you are looking for JavaScript™ for Acrobat® API Reference.

This reference should be the most complete. But, as @Orbling said, not all PDF viewers might support all of the API.

EDIT:

It turns out there are newer versions of the reference in Acrobat SDK (thanks to @jss).

Acrobat Developer Center contains links to different versions of documentation. Current version of JavaScript reference from Acrobat DC SDK is available there too.

Notice how the output of

SHOW GRANTS FOR 'root'@'localhost';

did not say 'ALL PRIVILEGES' but had to spell out what root@localhost has.

GRANT ALL PRIVILEGES will fail, because a user can not grant what he/she does not have, and the server seem to think something is not here ...

Now, what's missing then ?

There are also new tables in 5.5, such as mysql.proxies_user: make sure you have them.

When installing a brand new mysql server instance, the install script will create all the mysql.* tables with the proper structure.

When upgrading from an old version, make sure the proper upgrade procedure (mysql_upgrade) is used, which will add the missing tables / columns.

It is only a guess, but it seems mysql_upgrade was not done for this instance, causing the behavior seen.

So i just found a solution for that: In the hover animation do this:

animation: hover 1s infinite alternate ease-in-out,splash 1;

Here is something else I found:

1. After I have the "prefs" URL Scheme defined, "prefs:root=Safari&path=ContentBlockers" is working on Simulator (iOS 9.1 English), but not working on Simulator (Simplified Chinese). It just jump to Safari, but not Content Blockers. If your app is international, be careful.
   Update: Don't know why, now I can't jump into ContentBlockers anymore, the same code, the same version, doesn't work now. :(

2. On real devcies (mine is iPhone 6S & iPad mini 2), "Safari" should be "SAFARI", "Safari" not working on real device, "SAFARI" now working on simulator:

   #if arch(i386) || arch(x86_64)
       // Simulator
       let url = NSURL(string: "prefs:root=Safari")!
   #else
       // Device
       let url = NSURL(string: "prefs:root=SAFARI")!
   #endif
   
   if UIApplication.sharedApplication().canOpenURL(url) {
       UIApplication.sharedApplication().openURL(url)
   }
   

3. So far, did not find any differences between iPhone and iPad.

depending on the cryptography algorithm you are using, you may have to add some padding bytes at the end before encrypting a byte array so that the length of the byte array is multiple of the block size:

Specifically in your case the padding schema you chose is PKCS5 which is described here: http://www.rsa.com/products/bsafe/documentation/cryptoj35html/doc/dev_guide/group_CJ_SYM__PAD.html

(I assume you have the issue when you try to encrypt)

You can choose your padding schema when you instantiate the Cipher object. Supported values depend on the security provider you are using.

By the way are you sure you want to use a symmetric encryption mechanism to encrypt passwords? Wouldn't be a one way hash better? If you really need to be able to decrypt passwords, DES is quite a weak solution, you may be interested in using something stronger like AES if you need to stay with a symmetric algorithm.

You should trigger the animation to revert once it's completed w/ javascript.

  $(".item").live("animationend webkitAnimationEnd", function(){
    $(this).removeClass('animate');
  });

When working with fragments, instead of using this or refering to the context, always use getActivity(). You should call

getActivity().finish();

to finish your activity from fragment.

var obj = {
    'key1':'value',
    '2':'value',
    'key 1':'value'
}

console.log(obj.key1)
console.log(obj['key1'])
console.log(obj['2'])
console.log(obj['key 1'])

// will not work
console.log(obj.2)

Edit:

"I'm specifically looking to target the index, just like the first example - if it's possible."

Actually the 'index' is the key. If you want to store the position of a key you need to create a custom object to handle this.

I just realized what you were asking for(I hope). Here's an ugly solution

var preventClick = false;

$('#ThisLink').click(function(e) {
    $(this)
       .css('cursor', 'default')
       .css('text-decoration', 'none')

    if (!preventClick) {
        $(this).html($(this).html() + ' lalala');
    }

    preventClick = true;

    return false;
});

You're thinking of Boolean algebra.

This can also be done at the Project Level: In the Package Explorer, right-click on the project > Properties > Java Editor > Save Actions

This might be preferable when working as a team so that everyone's code is saved with the same format settings.

As Josh has stated above, you want to give each one the same name (letter, button, etc.) and all of them work. Then you want to surround all of these with a form tag:

<form name="myLetters" action="yourScript.php" method="POST">
<!-- Enter your values here with the following syntax: -->
<input type="radio" name="letter" value="A" /> A
<!-- Then add a submit value & close your form -->
<input type="submit" name="submit" value="Choose Letter!" />
</form>

Then, in the PHP script "yourScript.php" as defined by the action attribute, you can use:

$_POST['letter']

To get the value chosen.

MySQL has supported the ROW_NUMBER() since version 8.0+.

If you use MySQL 8.0 or later, check it out ROW_NUMBER() function. Otherwise, you have emulate ROW_NUMBER() function.

The row_number() is a ranking function that returns a sequential number of a row, starting from 1 for the first row.

for older version,

SELECT t.*, 
       @rowid := @rowid + 1 AS ROWID
  FROM TABLE t, 
       (SELECT @rowid := 0) dummy;

Depending on your application and the scope of the cfg file, a properties file might be the easiest. Sure it isn't as elegant as xml but it certainly easier.

There are two ways to download a file where the HTTP request requires that a header be set.

The credit for the first goes to @guest271314, and credit for the second goes to @dandavis.

The first method is to use the HTML5 File API to create a temporary local file, and the second is to use base64 encoding in conjunction with a data URI.

The solution I used in my project uses the base64 encoding approach for small files, or when the File API is not available, otherwise using the the File API approach.

Solution:

        var id = 123;

        var req = ic.ajax.raw({
            type: 'GET',
            url: '/api/dowloads/'+id,
            beforeSend: function (request) {

                    windowUrl.revokeObjectURL(url);
                }
                else {
                    //use base64 encoding when less than set limit or file API is not available
                    anchor.attr({
                        href: 'data:text/plain;base64,'+FormatUtils.utf8toBase64(result.response),
                        download: id+'.bin',
                    });
                    anchor.get(0).click();
                }

            }.bind(this),
            function reject(err) {
                console.log(err);
            }
        );

Note that I'm not using a raw XMLHttpRequest, and instead using ic-ajax, and should be quite similar to a jQuery.ajax solution.

Note also that you should substitute text/bin and .bin with whatever corresponds to the file type being downloaded.

The implementation of FormatUtils.utf8toBase64 can be found here

This is how I would do it (the code below has been tested, full source provided below), begin by creating a class with common properties

    class Word
    {
        public string Base { get; set; }
        public string Category { get; set; }
        public string Id { get; set; }
    }

load using XDocument with INPUT_DATA for demonstration purposes and find element name with lexicon . . .

    XDocument doc = XDocument.Parse(INPUT_DATA);
    XElement lex = doc.Element("lexicon");

make sure there is a value and use linq to extract the word elements from it . . .

    Word[] catWords = null;
    if (lex != null)
    {
        IEnumerable<XElement> words = lex.Elements("word");
        catWords = (from itm in words
                    where itm.Element("category") != null
                        && itm.Element("category").Value == "verb"
                        && itm.Element("id") != null
                        && itm.Element("base") != null
                    select new Word() 
                    {
                        Base = itm.Element("base").Value,
                        Category = itm.Element("category").Value,
                        Id = itm.Element("id").Value,
                    }).ToArray<Word>();
    }

The where statement checks if the category element exists and that the category value is not null and then check it again that it is a verb. Then check that the other nodes also exists . . .

The linq query will return an IEnumerable< Typename > object, so we can call ToArray< Typename >() to cast the entire collection into the type we want.

Then print it to get . . .

[Found]
 Id: E0006429
 Base: abandon
 Category: verb

[Found]
 Id: E0006524
 Base: abolish
 Category: verb

An example based on Chuck's answer:

myIntToStr :: Int -> String
myIntToStr x
    | x < 3     = show x ++ " is less than three"
    | otherwise = "normal"

Note that without the show the third line will not compile.

Use the defined? keyword (documentation). It will return a String with the kind of the item, or nil if it doesn’t exist.

>> a = 1
 => 1
>> defined? a
 => "local-variable"
>> defined? b
 => nil
>> defined? nil
 => "nil"
>> defined? String
 => "constant"
>> defined? 1
 => "expression"

As skalee commented: "It is worth noting that variable which is set to nil is initialized."

>> n = nil  
>> defined? n
 => "local-variable"

I tried this and it works without any issues to validate if the field is empty. I have answered your question partially as I haven't personally tried to add default values to attributes

if(field.getText()!= null && !field.getText().isEmpty())

Hope it helps

You can configure the output directory using the CONFIGURATION_BUILD_DIR environment variable.

Source: http://developer.apple.com/library/mac/#documentation/DeveloperTools/Reference/XcodeBuildSettingRef/0-Introduction/introduction.html#//apple_ref/doc/uid/TP40003931-CH1-SW1

this way i follow and its work for me fine, may it will works for you,

<iframe class="img-responsive" src="{{pdfLoc| trustThisUrl }}" ng-style="{
                height: iframeHeight * 0.75 + 'px'
            }" style="width:100%"></iframe>

here trustThisUrl is just filter,

angular.module("app").filter('trustThisUrl', ["$sce", function ($sce) {
        return function (val) {
            return $sce.trustAsResourceUrl(val);
        };
    }]);

To answer your questions in a easy way:

    a) String.length();
    b) String.charAt(/* String index */);

I was facing the same issue then i made my key 16 byte and it's working properly now. Create your key exactly 16 byte. It will surely work.

sh is interpreting the && as a shell operator. Change it to -a, that’s [’s conjunction operator:

[ "$arg1" = "$arg2" -a "$arg1" != "$arg3" ]

Also, you should always quote the variables, because [ gets confused when you leave off arguments.

You could also, in another directory:

• git clone [your repository]
• Overwrite the .git directory in your original repository with the .git directory of the repository you just cloned right now.
• git add and git commit your original

irb(main)> varA
=> {0=>["12", "34", "35", "231"]}
irb(main)> varA = Hash[*ex.collect{|a,b| [a,b.join(",")]}.flatten]
...

It's also cleaner to use @JoinTable when an Entity could be the child in several parent/child relationships with different types of parents. To follow up with Behrang's example, imagine a Task can be the child of Project, Person, Department, Study, and Process.

Should the task table have 5 nullable foreign key fields? I think not...

You may also try try -Dmaven.clean.failOnError=false (from Maven FAQ)

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

You can use the vue-head package to add scripts, and other tags to the head of your vue component.

Its as simple as:

var myComponent = Vue.extend({
  data: function () {
    return {
      ...
    }
  },
  head: {
    title: {
      inner: 'It will be a pleasure'
    },
    // Meta tags
    meta: [
      { name: 'application-name', content: 'Name of my application' },
      { name: 'description', content: 'A description of the page', id: 'desc' }, // id to replace intead of create element
      // ...
      // Twitter
      { name: 'twitter:title', content: 'Content Title' },
      // with shorthand
      { n: 'twitter:description', c: 'Content description less than 200 characters'},
      // ...
      // Google+ / Schema.org
      { itemprop: 'name', content: 'Content Title' },
      { itemprop: 'description', content: 'Content Title' },
      // ...
      // Facebook / Open Graph
      { property: 'fb:app_id', content: '123456789' },
      { property: 'og:title', content: 'Content Title' },
      // with shorthand
      { p: 'og:image', c: 'https://example.com/image.jpg' },
      // ...
    ],
    // link tags
    link: [
      { rel: 'canonical', href: 'http://example.com/#!/contact/', id: 'canonical' },
      { rel: 'author', href: 'author', undo: false }, // undo property - not to remove the element
      { rel: 'icon', href: require('./path/to/icon-16.png'), sizes: '16x16', type: 'image/png' }, 
      // with shorthand
      { r: 'icon', h: 'path/to/icon-32.png', sz: '32x32', t: 'image/png' },
      // ...
    ],
    script: [
      { type: 'text/javascript', src: 'cdn/to/script.js', async: true, body: true}, // Insert in body
      // with shorthand
      { t: 'application/ld+json', i: '{ "@context": "http://schema.org" }' },
      // ...
    ],
    style: [
      { type: 'text/css', inner: 'body { background-color: #000; color: #fff}', undo: false },
      // ...
    ]
  }
})

Or just simply using the datetime standard module

In [2]: from datetime import timezone, datetime
   ...: int(datetime.now(tz=timezone.utc).timestamp() * 1000)
   ...: 
Out[2]: 1514901741720

You can truncate or multiply depending on the resolution you want. This example is outputting millis.

If you want a proper Unix timestamp (in seconds) remove the * 1000

The error occurred when I unknowingly tried plotting the image path instead of the image.

My code :

import cv2 as cv
from matplotlib import pyplot as plt
import pytesseract
from resizeimage import resizeimage

img = cv.imread("D:\TemplateMatch\\fitting.png") ------>"THIS IS THE WRONG USAGE"
#cv.rectangle(img,(29,2496),(604,2992),(255,0,0),5)
plt.imshow(img)

Correction: img = cv.imread("fitting.png") --->THIS IS THE RIGHT USAGE"

I suppose your html page is hosted on a different port. Same origin policy requires in most browsers that the loaded file be on the same port than the loading file.

You can just basically revert your code using some other built in methods.

byte[] decodedString = Base64.decode(encodedImage, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); 

If (UserID, Date) is unique, i.e. no date appears twice for the same user then:

select TheTable.UserID, TheTable.Value
from TheTable inner join (select UserID, max([Date]) MaxDate
                          from TheTable
                          group by UserID) UserMaxDate
     on TheTable.UserID = UserMaxDate.UserID
        TheTable.[Date] = UserMaxDate.MaxDate;

Add

export PATH=$PATH:/home/me/play

to your ~/.profile and execute

source ~/.profile 

in order to immediately reflect changes to your current terminal instance.

You might want to use your local file as a last resort.

Seems as of now jQuery's own CDN does not support https. If it did you then might want to load from there first.

So here's the sequence: Google CDN => Microsoft CDN => Your local copy.

<!-- load jQuery from Google's CDN -->
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> 
<!-- fallback to Microsoft's Ajax CDN -->
<script> window.jQuery || document.write('<script src="//ajax.aspnetcdn.com/ajax/jQuery/jquery-1.8.3.min.js">\x3C/script>')</script> 
<!-- fallback to local file -->
<script> window.jQuery || document.write('<script src="Assets/jquery-1.8.3.min.js">\x3C/script>')</script> 

I would try to call

spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());

after you call setAdapter(). Also try out calling before the adapter.

You always have the solution to go with subclassing, where you can wrap a boolean flag to your overriden setAdapter method to skip the event.

An easy fix

If you have only one type of collections (e.g. scatter with no error bars) you can also change the colours after that you have plotted them, this sometimes is easier to perform.

import matplotlib.pyplot as plt
from random import randint
import numpy as np

#Let's generate some random X, Y data X = [ [frst group],[second group] ...]
X = [ [randint(0,50) for i in range(0,5)] for i in range(0,24)]
Y = [ [randint(0,50) for i in range(0,5)] for i in range(0,24)]
labels = range(1,len(X)+1)

fig = plt.figure()
ax = fig.add_subplot(111)
for x,y,lab in zip(X,Y,labels):
        ax.scatter(x,y,label=lab)

The only piece of code that you need:

#Now this is actually the code that you need, an easy fix your colors just cut and paste not you need ax.
colormap = plt.cm.gist_ncar #nipy_spectral, Set1,Paired  
colorst = [colormap(i) for i in np.linspace(0, 0.9,len(ax.collections))]       
for t,j1 in enumerate(ax.collections):
    j1.set_color(colorst[t])


ax.legend(fontsize='small')

The output gives you differnent colors even when you have many different scatter plots in the same subplot.

Here is my solution

private static final int NOTIFICATION_ID = 200;

private static final String CHANNEL_NAME = "myChannelName";

private void startForeground() {

    final NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
            getApplicationContext(), CHANNEL_ID);

    Notification notification;



        notification = mBuilder.setTicker(getString(R.string.app_name)).setWhen(0)

            NotificationChannel channel = new NotificationChannel(CHANNEL_ID,
                    CHANNEL_NAME,
                    NotificationManager.IMPORTANCE_DEFAULT);
            notificationManager.createNotificationChannel(channel);

        }
        notificationManager.notify(NOTIFICATION_ID, notification);

    }

Hope it will help :)

Also with dict

a = []
b = {1:'one'}

a.append(dict(b))
print a
b[1]='iuqsdgf'
print a

result

[{1: 'one'}]
[{1: 'one'}]

You can always do this from finder. Simply navigate to the directory above where the mount is and hit the eject icon over the mounted folder, which will have SSHFS in the name (in the finder). A shortcut to open a folder in the finder from the terminal is

open .

which will open up the current directory in a new finder window. Replace "." with your directory of choice.

I ran into this on my Mac using the MacPorts vim with +python. Problem was that the MacPorts vim will only bind to python 2.5 with +python, while my extensions were installed under python 2.7. Installing the extensions using pip-2.5 solved it.

Change detection

Only @Component can be a node in the change detection tree. This means that you cannot set ChangeDetectionStrategy.OnPush in a @Directive. Despite this fact, a Directive can have @Input and @Output properties and you can inject and manipulate host component's ChangeDetectorRef from it. So use Components when you need a granular control over your change detection tree.

If you're using Python 2.x, try installing a urllib2 opener. That should print out your headers, although you may have to combine that with other openers you're using to hit the HTTPS.

import urllib2
urllib2.install_opener(urllib2.build_opener(urllib2.HTTPHandler(debuglevel=1)))
urllib2.urlopen(url)

Its due to access control security policies specifically when SELinux is enabled it won't allow external executables to create temporary files in the system locations.

Disable SELinux by issuing below command:

echo 0 >/selinux/enforce

You can now start mysql it wont give any permission related errror while reading/writing to /tmp or system directories.

In case you wish to enable the SELinux security back change 0 to 1 in above command.

you can try these:

document.getElementById("RootNode").onclick = function(){/*do something*/};

or

$('#RootNode').click(function(){/*do something*/});

or

$(document).on("click", "#RootNode", function(){/*do something*/});

There is a point for the first two method which is, it matters where in your page DOM, you should put them, the whole DOM should be loaded, to be able to find the, which is usually it gets solved if you wrap them in a window.onload or DOMReady event, like:

//in Vanilla JavaScript
window.addEventListener("load", function(){
     document.getElementById("RootNode").onclick = function(){/*do something*/};
});
//for jQuery
$(document).ready(function(){
    $('#RootNode').click(function(){/*do something*/});
});

The ASIDE has since been modified to include secondary content as well.

HTML5 Doctor has a great writeup on it here: http://html5doctor.com/aside-revisited/

Excerpt:

With the new definition of aside, it’s crucial to remain aware of its context. >When used within an article element, the contents should be specifically related >to that article (e.g., a glossary). When used outside of an article element, the >contents should be related to the site (e.g., a blogroll, groups of additional >navigation, and even advertising if that content is related to the page).

I've been able to do this using SVG filter. You can write a filter that multiplies the color of source image with the color you want to change to. In the code snippet below, flood-color is the color we want to change image color to (which is Red in this case.) feComposite tells the filter how we're processing the color. The formula for feComposite with arithmetic is (k1*i1*i2 + k2*i1 + k3*i2 + k4) where i1 and i2 are input colors for in/in2 accordingly. So specifying only k1=1 means it will do just i1*i2, which means multiplying both input colors together.

Note: This only works with HTML5 since this is using inline SVG. But I think you might be able to make this work with older browser by putting SVG in a separate file. I haven't tried that approach yet.

Here's the snippet:

This might work well to remove special characters.

After an hour or two of trying every combination of ui-view autoscroll=true, $stateChangeStart, $locationChangeStart, $uiViewScrollProvider.useAnchorScroll(), $provide('$uiViewScroll', ...), and many others, I couldn't get scroll-to-top-on-new-page to work as expected.

This was ultimately what worked for me. It captures pushState and replaceState and only updates scroll position when new pages are navigated to (back/forward button retain their scroll positions):

.run(function($anchorScroll, $window) {
  // hack to scroll to top when navigating to new URLS but not back/forward
  var wrap = function(method) {
    var orig = $window.window.history[method];
    $window.window.history[method] = function() {
      var retval = orig.apply(this, Array.prototype.slice.call(arguments));
      $anchorScroll();
      return retval;
    };
  };
  wrap('pushState');
  wrap('replaceState');
})

From Perl HowTo, the most common ways to execute external commands from Perl are:

• my $files = `ls -la` — captures the output of the command in $files
• system "touch ~/foo" — if you don't want to capture the command's output
• exec "vim ~/foo" — if you don't want to return to the script after executing the command
• open(my $file, '|-', "grep foo"); print $file "foo\nbar" — if you want to pipe input into the command

addAccordian(type, data) { console.log(type, data);

let form = this.form;

if (!form.controls[type]) {
  let ownerAccordian = new FormArray([]);
  const group = new FormGroup({});
  ownerAccordian.push(
    this.applicationService.createControlWithGroup(data, group)
  );
  form.controls[type] = ownerAccordian;
} else {
  const group = new FormGroup({});
  (<FormArray>form.get(type)).push(
    this.applicationService.createControlWithGroup(data, group)
  );
}
console.log(this.form);

STEP1: I created a field of type varbinary in table

STEP2: I created a stored procedure to accept a parameter of type sql_variant

STEP3: In my front end asp.net page, I created a sql data source parameter of object type

        <tr>
        <td>
            UPLOAD DOCUMENT</td>
        <td>
            <asp:FileUpload ID="FileUpload1" runat="server" />
            <asp:Button ID="btnUpload" runat="server" Text="Upload" />
            <asp:SqlDataSource ID="sqldsFileUploadConn" runat="server" 
                ConnectionString="<%$ ConnectionStrings: %>" 
                InsertCommand="ph_SaveDocument"     
               InsertCommandType="StoredProcedure">
                <InsertParameters>
                    <asp:Parameter Name="DocBinaryForm" Type="Object" />
                </InsertParameters>

             </asp:SqlDataSource>
        </td>
        <td>
            &nbsp;</td>
    </tr>

STEP 4: In my code behind, I try to upload the FileBytes from FileUpload Control via this stored procedure call using a sql data source control

      Dim filebytes As Object
      filebytes = FileUpload1.FileBytes()
      sqldsFileUploadConn.InsertParameters("DocBinaryForm").DefaultValue = filebytes.ToString
      Dim uploadstatus As Int16 = sqldsFileUploadConn.Insert()

               ' ... code continues ... '

I wouldn't push regular code into an exception block. Just check whether any rows exist that meet your condition, and proceed from there:

declare
  any_rows_found number;
begin
  select count(*)
  into   any_rows_found
  from   my_table
  where  rownum = 1 and
         ... other conditions ...

  if any_rows_found = 1 then
    ...
  else
    ...
  end if;

My solution is:

            int[] spinnerLocation = {0,0};
            spinner.getLocationOnScreen(spinnerLocation);

            int[] scrollLocation = {0, 0};
            scrollView.getLocationInWindow(scrollLocation);

            int y = scrollView.getScrollY();

            scrollView.smoothScrollTo(0, y + spinnerLocation[1] - scrollLocation[1]);

You're removing and then incrementing, which means you'll be one ahead of yourself. Instead, remove in reverse so you never mess up your next item.

for (int i = ChunkList.Count-1; i >=0; i--)
{
    if (ChunkList[i].UniqueID == ChunkID)
    {
        ChunkList.RemoveAt(i);
    }
}

Given a file named Me.Jar:

1. Go to cmd
2. Hit Enter

3. Use the Java jar command -- I am using jdk1.8.0_31 so I would type

   C:\Program Files (x86)\Java\jdk1.8.0_31\bin\jar xf me.jar

That should extract the file to the folder bin. Look for the file .class in my case my Me.jar contains a Valentine.class

Type java Valentine and press Enter and your message file will be opened.

By default, when a flutter app gets installed, the app name on the launcher is your Flutter project name. To change that to your desired application name on Android or iOS both, you need to change AndroidManifest.xml and Info.plist respectively. here is a two way to achieve this

1 By plugin

You can use a flutter rename plugin. It helps you to change your flutter project's AppName and BundleId for different platforms, currently only available for iOS, Android and macOS

You can change the bundleId and appName in the following steps

Default Usage if you dont pass -t or --target parameter it will try to rename all available platform project folders inside flutter project.

Run this command inside your flutter project root.

pub global run rename --bundleId com.onatcipli.networkUpp
pub global run rename --appname "Test App Name"

Custom Usage if you want to run commands directly (without using pub global run) ensure you add system catche bin directory to your path

rename --appname yourappname -t ios

or

pub global run rename --appname yourappname --target macOS

To target a specific platform use the "--target" option. e.g.

pub global run rename --bundleId com.example.android.app --target android

2 By manual

For Android

App Name is reflected under Android>src>main>Androidmanifest.xml The label name in the Android manifest is responsible for giving the App Name for Android Application

Go to AndroidManifest.xml, find <application> tag. Change its android:label property with your desired app name.

Navigate to the : android/app/src/main/AndroidManifest.xml

The Androidmanifest.xml can now be modified. Choose the

<application
  android:name="io.flutter.app.FlutterApplication"
  android:label="YourAppName"
  android:icon="@mipmap/ic_launcher">

For Package Name

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="your.package.name">

This portion represents the actual Android file naming system. Important information like Launcher Icon and App name can be controlled here. Modify the android:label to change the App Name only.

For iOS

For iOS, open info.plist. Change CFBundleName (Bundle Name).

Go to the Xcode project folder and open Info.plist for edit (in Xcode you can choose Open As > Source Code in the file context menu). All we need is to edit the value for key CFBundleName. It’s a user-visible short name for the bundle.

Navigate to the: project/ios/Runner/Info.plist

Find the CFBundleName <key>. This denotes the Key that holds the app name. The app name now can be changed by modifying the <String> </String> below that.

<key>CFBundleName</key>
<string>YouAppName</string>

That’s it. By having these changes, That’s achieved, an updated application name in the launcher when an app gets installed on a device. your new app name will be displayed on your phone now.

You can also name columns directly in the cbind call, e.g.

cbind(date=c(0,1), high=c(2,3))

Output:

     date high
[1,]    0    2
[2,]    1    3

Android Studio 4.1.1 If you want to create the debug apk, and just before creating the apk you tried running on your phone/simulator (doing create signed apk right away will cause the APP NOT INSTALLED),YOU SHOULD CLEAN THE PROJECT before creating signed bundle/apk

Several options, by order of most appropriate way:

1. Return an int from the Program.Main method
2. Throw an exception and don't handle it anywhere (use for unexpected error situations)
3. To force termination elsewhere, System.Environment.Exit (not portable! see below)

Edited 9/2013 to improve readability

Returning with a specific exit code: As Servy points out in the comments, you can declare Main with an int return type and return an error code that way. So there really is no need to use Environment.Exit unless you need to terminate with an exit code and can't possibly do it in the Main method. Most probably you can avoid that by throwing an exception, and returning an error code in Main if any unhandled exception propagates there. If the application is multi-threaded you'll probably need even more boilerplate to properly terminate with an exit code so you may be better off just calling Environment.Exit.

Another point against using Evironment.Exit - even when writing multi-threaded applications - is reusability. If you ever want to reuse your code in an environment that makes Environment.Exit irrelevant (such as a library that may be used in a web server), the code will not be portable. The best solution still is, in my opinion, to always use exceptions and/or return values that represent that the method reached some error/finish state. That way, you can always use the same code in any .NET environment, and in any type of application. If you are writing specifically an app that needs to return an exit code or to terminate in a way similar to what Environment.Exit does, you can then go ahead and wrap the thread at the highest level and handle the errors/exceptions as needed.

In C++11 you could also create an alias for convenience:

template<class T> using min_heap = priority_queue<T, std::vector<T>, std::greater<T>>;

And use it like this:

min_heap<int> my_heap;

With Oracle 11g R2 (at least with 11.2.02) there is a view named datapump_dir_objs.

SELECT * FROM datapump_dir_objs;

The view shows the NAME of the directory object, the PATH as well as READ and WRITE permissions for the currently connected user. It does not show any directory objects which the current user has no permission to read from or write to, though.

Use npm outdated to see Current and Latest version of all packages.

Then npm i packageName@versionNumber to install specific version : example npm i [email protected].

Or npm i packageName@latest to install latest version : example npm i browser-sync@latest.

You can use Named Sections.

_Layout.cshtml

<head>
    <script type="text/javascript" src="@Url.Content("/Scripts/jquery-1.6.2.min.js")"></script>
    @RenderSection("JavaScript", required: false)
</head>

_SomeView.cshtml

@section JavaScript
{
   <script type="text/javascript" src="@Url.Content("/Scripts/SomeScript.js")"></script>
   <script type="text/javascript" src="@Url.Content("/Scripts/AnotherScript.js")"></script>
}

I would recommend you to use worksheet's index instead of using worksheet's name, in this way you can also loop through sheets "dynamically"

for i=1 to thisworkbook.sheets.count
 sheets(i).activate
'You can add more code 
with activesheet
 'Code...
end with
next i

It will also, improve performance.

I found a solution:

print("My message here");

If you just need to try something out quickly, here's a quick and dirty solution. Use single quotes for the attribute value:

<parameter name='Quote = " '>

Solution with TC - O(n) and SC - O(1)

public String reverseString(String str){
    String str = "Hello Wrold";
    int start = 0;

    for (int i = 0; i < str.length(); i++) {

        if (str.charAt(i) == ' ' || i == str.length() - 1) {

            int end = 0;

            if (i == str.length() - 1) {
                end = i;
            } else {
                end = i - 1;
            }

            str = swap(str, start, end);
            start = i + 1;
        }
    }
    System.out.println(str);
   }

 private static String swap(String str, int start, int end) {

    StringBuilder sb = new StringBuilder(str);

    while (start < end) {
        sb.setCharAt(start, str.charAt(end));
        sb.setCharAt(end, str.charAt(start));
        start++;
        end--;
    }
    return sb.toString();

I use this:

Math.round(Date.now() / 1000)

No need for new object creation (see doc Date.now())

Best solution would be to convert existing databases BEFORE upgrading to newer version/s of Access. Surely Microsoft should be warning users about this problem when upgrades are about to be installed.

Underneath the file system, files are represented by inodes. (Or is it multiple inodes? Not sure.)

A file in the file system is basically a link to an inode.
A hard link, then, just creates another file with a link to the same underlying inode.

When you delete a file, it removes one link to the underlying inode. The inode is only deleted (or deletable/over-writable) when all links to the inode have been deleted.

A symbolic link is a link to another name in the file system.

Once a hard link has been made the link is to the inode. Deleting, renaming, or moving the original file will not affect the hard link as it links to the underlying inode. Any changes to the data on the inode is reflected in all files that refer to that inode.

Note: Hard links are only valid within the same File System. Symbolic links can span file systems as they are simply the name of another file.

Using jQuery

$('#note textarea');

or just

$('#textid');

You can use this service I wrote to handle everything for you.

This service will request the permissions and handle dealing with the CLLocationManager so you don't have to.

Use like this:

LocationService.getCurrentLocationOnSuccess({ (latitude, longitude) -> () in
    //Do something with Latitude and Longitude

    }, onFailure: { (error) -> () in

      //See what went wrong
      print(error)
})

prop.table is a nice friendly way of obtaining proportions of tables.

m <- matrix(1:4,2)

 m
     [,1] [,2]
[1,]    1    3
[2,]    2    4

Leaving margin blank gives you proportions of the whole table

 prop.table(m, margin=NULL)
     [,1] [,2]
[1,]  0.1  0.3
[2,]  0.2  0.4

Giving it 1 gives you row proportions

 prop.table(m, 1)
      [,1]      [,2]
[1,] 0.2500000 0.7500000
[2,] 0.3333333 0.6666667

And 2 is column proportions

 prop.table(m, 2)
          [,1]      [,2]
[1,] 0.3333333 0.4285714
[2,] 0.6666667 0.5714286

TL;DR. In Visual Studio 2019, when you add an Icon resource to a Win32 (desktop) application you get an auto-generated icon file that has the formats below. I assume that the #1 developer tool for Windows does this right. Thus, a Windows compatible should have the following formats:

| Resolution | Color depth | Format |
|:-----------|------------:|:------:|
| 256x256    |      32-bit |  PNG   |
| 64x64      |      32-bit |  BMP   |
| 48x48      |      32-bit |  BMP   |
| 32x32      |      32-bit |  BMP   |
| 16x16      |      32-bit |  BMP   |
| 48x48      |       8-bit |  BMP   |
| 32x32      |       8-bit |  BMP   |
| 16x16      |       8-bit |  BMP   |

You can use the Object.values() method if you dont want to use the Object.keys().

As opposed to the Object.keys() method that returns an array of a given object's own enumerable properties, so for instance:

const object1 = {
 a: 'somestring',
 b: 42,
 c: false
};

console.log(Object.keys(object1));

Would print out the following array:

[ 'a', 'b', 'c' ]

The Object.values() method returns an array of a given object's own enumerable property values.

So if you have the same object but use values instead,

const object1 = {
 a: 'somestring',
 b: 42,
 c: false
};

console.log(Object.values(object1));

You would get the following array:

[ 'somestring', 42, false ]

So if you wanted to access the object1.b, but using an index instead you could use:

Object.values(object1)[1] === 42

You can read more about this method here.

Ruby uses "pass by object reference"

(Using Python's terminology.)

To say Ruby uses "pass by value" or "pass by reference" isn't really descriptive enough to be helpful. I think as most people know it these days, that terminology ("value" vs "reference") comes from C++.

In C++, "pass by value" means the function gets a copy of the variable and any changes to the copy don't change the original. That's true for objects too. If you pass an object variable by value then the whole object (including all of its members) get copied and any changes to the members don't change those members on the original object. (It's different if you pass a pointer by value but Ruby doesn't have pointers anyway, AFAIK.)

class A {
  public:
    int x;
};

void inc(A arg) {
  arg.x++;
  printf("in inc: %d\n", arg.x); // => 6
}

void inc(A* arg) {
  arg->x++;
  printf("in inc: %d\n", arg->x); // => 1
}

int main() {
  A a;
  a.x = 5;
  inc(a);
  printf("in main: %d\n", a.x); // => 5

  A* b = new A;
  b->x = 0;
  inc(b);
  printf("in main: %d\n", b->x); // => 1

  return 0;
}

Output:

in inc: 6
in main: 5
in inc: 1
in main: 1

In C++, "pass by reference" means the function gets access to the original variable. It can assign a whole new literal integer and the original variable will then have that value too.

void replace(A &arg) {
  A newA;
  newA.x = 10;
  arg = newA;
  printf("in replace: %d\n", arg.x);
}

int main() {
  A a;
  a.x = 5;
  replace(a);
  printf("in main: %d\n", a.x);

  return 0;
}

Output:

in replace: 10
in main: 10

Ruby uses pass by value (in the C++ sense) if the argument is not an object. But in Ruby everything is an object, so there really is no pass by value in the C++ sense in Ruby.

In Ruby, "pass by object reference" (to use Python's terminology) is used:

• Inside the function, any of the object's members can have new values assigned to them and these changes will persist after the function returns.*
• Inside the function, assigning a whole new object to the variable causes the variable to stop referencing the old object. But after the function returns, the original variable will still reference the old object.

Therefore Ruby does not use "pass by reference" in the C++ sense. If it did, then assigning a new object to a variable inside a function would cause the old object to be forgotten after the function returned.

class A
  attr_accessor :x
end

def inc(arg)
  arg.x += 1
  puts arg.x
end

def replace(arg)
  arg = A.new
  arg.x = 3
  puts arg.x
end

a = A.new
a.x = 1
puts a.x  # 1

inc a     # 2
puts a.x  # 2

replace a # 3
puts a.x  # 2

puts ''

def inc_var(arg)
  arg += 1
  puts arg
end

b = 1     # Even integers are objects in Ruby
puts b    # 1
inc_var b # 2
puts b    # 1

Output:

1
2
2
3
2

1
2
1

* This is why, in Ruby, if you want to modify an object inside a function but forget those changes when the function returns, then you must explicitly make a copy of the object before making your temporary changes to the copy.

If you have two projects in one solution folder.Just add the Reference of the Project into another.using the Namespace you can get the classes. While Creating the object for that the requried class. Call the Method which you want.

FirstProject:

class FirstClass()
{
   public string Name()
   {
      return "James";
   }
}

Here add reference to the Second Project

SecondProject:

class SeccondClass
{
    FirstProject.FirstClass obj=new FirstProject.FirstClass();
    obj.Name();
}

Passing structs to functions by reference: simply :)

#define maxn 1000

struct solotion
{
    int sol[maxn];
    int arry_h[maxn];
    int cat[maxn];
    int scor[maxn];

};

void inser(solotion &come){
    come.sol[0]=2;
}

void initial(solotion &come){
    for(int i=0;i<maxn;i++)
        come.sol[i]=0;
}

int main()
{
    solotion sol1;
    inser(sol1);
    solotion sol2;
    initial(sol2);
}

C# arrays are fixed length and always indexed. Go with Motti's solution:

int [] terms = new int[400];
for(int runs = 0; runs < 400; runs++)
{
    terms[runs] = value;
}

Note that this array is a dense array, a contiguous block of 400 bytes where you can drop things. If you want a dynamically sized array, use a List<int>.

List<int> terms = new List<int>();
for(int runs = 0; runs < 400; runs ++)
{
    terms.Add(runs);
}

Neither int[] nor List<int> is an associative array -- that would be a Dictionary<> in C#. Both arrays and lists are dense.

You can use the unzip command.

You could add justify-content: space-between to the parent element. In doing so, the children flexbox items will be aligned to opposite sides with space between them.

Updated Example

#container {
    width: 500px;
    border: solid 1px #000;
    display: flex;
    justify-content: space-between;
}

#container {_x000D_
    width: 500px;_x000D_
    border: solid 1px #000;_x000D_
    display: flex;_x000D_
    justify-content: space-between;_x000D_
}_x000D_
_x000D_
#a {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
}_x000D_
_x000D_
#b {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
    height: 200px;_x000D_
}

<div id="container">_x000D_
    <div id="a">_x000D_
        a_x000D_
    </div>_x000D_
    <div id="b">_x000D_
        b_x000D_
    </div>_x000D_
</div>

You could also add margin-left: auto to the second element in order to align it to the right.

Updated Example

#b {
    width: 20%;
    border: solid 1px #000;
    height: 200px;
    margin-left: auto;
}

#container {_x000D_
    width: 500px;_x000D_
    border: solid 1px #000;_x000D_
    display: flex;_x000D_
}_x000D_
_x000D_
#a {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
    margin-right: auto;_x000D_
}_x000D_
_x000D_
#b {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
    height: 200px;_x000D_
    margin-left: auto;_x000D_
}

<div id="container">_x000D_
    <div id="a">_x000D_
        a_x000D_
    </div>_x000D_
    <div id="b">_x000D_
        b_x000D_
    </div>_x000D_
</div>

I guess your code uses somewhere in the second case a singular matrix (i.e. not invertible), and the solve function needs to invert it. This has nothing to do with the size but with the fact that some of your vectors are (probably) colinear.

dtList  = dtList.Where(s => !string.IsNullOrWhiteSpace(s)).Distinct().ToList()

I assumed empty string and whitespace are like null. If not you can use IsNullOrEmpty (allow whitespace), or s != null

I would update the formula in C1. Then copy the formula from C1 and paste it till C10...

Not sure about a more elegant solution

Range("C1").Formula = "=A1+B1"
Range("C1").Copy
Range("C1:C10").Pastespecial(XlPasteall)

It’s just HTML with Server Side Includes.

Once I've seen such an interesting construction:

<Ids xmlns:id="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
        <id:int>1787</id:int>
</Ids>

Honestly alot of the answers are old so i found that if you simply just test any string regardless of character content with "/.*/i" will sufficiently get EVERYTHING.

Maybe late to the party but in my case it was RHEL 6.8:

Copy certificate.crt issued by hosting to:

/etc/pki/ca-trust/source/anchors/

Then:

update-ca-trust force-enable (ignore not found warnings)
update-ca-trust extract

Hope it helps

Try this

function checkForm($fields){
        foreach($fields as $field){
            if($field['required'] && strlen($_POST[$field['name']]) <= 0){
                $field['value'] = "Some error";
            }
        }
        return $field;
    }

Now in new version magento2 on Generate error Service Temporarily Unavailable.

Remove maintenance.flag

From this path which is changed magento2/var/maintenance.flag.

Also

$ rm maintenance.flag

You should try something like this, I am doing this for my project, its a fallback system

//function to get the remote data
function url_get_contents ($url) {
    if (function_exists('curl_exec')){ 
        $conn = curl_init($url);
        curl_setopt($conn, CURLOPT_SSL_VERIFYPEER, true);
        curl_setopt($conn, CURLOPT_FRESH_CONNECT,  true);
        curl_setopt($conn, CURLOPT_RETURNTRANSFER, 1);
        $url_get_contents_data = (curl_exec($conn));
        curl_close($conn);
    }elseif(function_exists('file_get_contents')){
        $url_get_contents_data = file_get_contents($url);
    }elseif(function_exists('fopen') && function_exists('stream_get_contents')){
        $handle = fopen ($url, "r");
        $url_get_contents_data = stream_get_contents($handle);
    }else{
        $url_get_contents_data = false;
    }
return $url_get_contents_data;
} 

then later you can do like this

$data = url_get_contents("http://www.google.com");
if($data){
//Do Something....
}

An easier way to get the machine epsilon for a given float type is to use np.finfo():

print(np.finfo(float).eps)
# 2.22044604925e-16

print(np.finfo(np.float32).eps)
# 1.19209e-07

This should work: use a back slash and put a double quote

"UPDATE my_table SET row =\"hi, my name's tim.\";

I am doing some basic array in JGrasp and found that with an accessor method for a char[][] array to use ('.') to place a single dot.

Just install package Synced?Sidebar?Bg:it will change the sidebar theme based on current color scheme.But it seems that every time you change the color scheme,sidebar will be changed after you open file Preferences.sublime-settings

You can force the annotation library in your test using:

androidTestCompile 'com.android.support:support-annotations:23.1.0'

Something like this:

  // Force usage of support annotations in the test app, since it is internally used by the runner module.
  androidTestCompile 'com.android.support:support-annotations:23.1.0'
  androidTestCompile 'com.android.support.test:runner:0.4.1'
  androidTestCompile 'com.android.support.test:rules:0.4.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-web:2.2.1'

Another solution is to use this in the top level file:

configurations.all {
    resolutionStrategy.force 'com.android.support:support-annotations:23.1.0'
}

I was getting this error in postgresql function. I had a long SQL which I broke into multiple lines with \ for better readability. However, that was the problem. I removed all and made them in one line to fix the issue. I was using pgadmin III.

Google's Guava library handles this in the IntMath class:

IntMath.divide(numerator, divisor, RoundingMode.CEILING);

Unlike many answers here, it handles negative numbers. It also throws an appropriate exception when attempting to divide by zero.

Swift 3 version

import UIKit

protocol PhoneCalling {
    func call(phoneNumber: String)
}

extension PhoneCalling {
    func call(phoneNumber: String) {
        let cleanNumber = phoneNumber.replacingOccurrences(of: " ", with: "").replacingOccurrences(of: "-", with: "")
        guard let number = URL(string: "telprompt://" + cleanNumber) else { return }

        UIApplication.shared.open(number, options: [:], completionHandler: nil)
    }
}

This should do when your date is in this format (dd/mm/yyyy).

  sortByDate(arr) {
    arr.sort(function(a,b){
      return Number(new Date(a.readableDate)) - Number(new Date(b.readableDate));
    });

    return arr;
  }

Then call sortByDate(myArr);

replace "150x150" with 720x720 and remove /vp/ from the link.it should work.

First, you should understand the pointer is not complex. A pointer is showing the address of the variable.

Example:

int a = 10;
int *p = &a;  // This means giving a pointer of variable "a" to int pointer variable "p"

And, you should understand "Pointer is an address" and "address is numerical value". So, you can get the address of variable as Integer.

int a = 10;
unsigned long address = (unsigned long)&a;

// comparison
printf("%p\n", &a);
printf("%ld\n", address);

output is below

0x7fff1216619c
7fff1216619c

Note:

If you use a 64-bit computer, you can't get pointer by the way below.

int a = 10;
unsigned int address = (unsigned int)&a;

Because pointer is 8 bytes (64 bit) on a 64-bit machine, but int is 4 bytes. So, you can't give an 8-byte memory address to 4 bytes variable.

You have to use long long or long to get an address of the variable.

• long long is always 8 bytes.
• long is 4 bytes when code was compiled for a 32-bit machine.
• long is 8 bytes when code was compiled for a 64-bit machine.

Therefore, you should use long to receive a pointer.

Here is variant of @juraj-blahunka's lightweight approach. This function does not assume the container is the document and only scrolls if the item is out of view. Animation queuing is also disabled to avoid unnecessary bouncing.

$.fn.scrollToView = function () {
    return $.each(this, function () {
        if ($(this).position().top < 0 ||
            $(this).position().top + $(this).height() > $(this).parent().height()) {
            $(this).parent().animate({
                scrollTop: $(this).parent().scrollTop() + $(this).position().top
            }, {
                duration: 300,
                queue: false
            });
        }
    });
};

Though the above answers have covered, I have just tried to add minute detail s which i see missing. The reason behind them(The Why).

Illustration:

Sample.java
---------------
    public class Sample{
        DependencyOne dependencyOne;
        DependencyTwo dependencyTwo;


        public SampleResponse methodOfSample(){
            dependencyOne.methodOne();
            dependencyTwo.methodTwo();

            ...

            return sampleResponse;
        }
    }

SampleTest.java
-----------------------
@RunWith(PowerMockRunner.class)
@PrepareForTest({ClassA.class})
public class SampleTest{

    @InjectMocks
    Sample sample;

    @Mock
    DependencyOne dependencyOne;

    @Mock
    DependencyTwo dependencyTwo;

    @Before
    public void init() {
        MockitoAnnotations.initMocks(this);
    }

    public void sampleMethod1_Test(){
        //Arrange the dependencies
        DependencyResponse dependencyOneResponse = Mock(sampleResponse.class);
        Mockito.doReturn(dependencyOneResponse).when(dependencyOne).methodOne();

        DependencyResponse dependencyTwoResponse = Mock(sampleResponse.class);
        Mockito.doReturn(dependencyOneResponse).when(dependencyTwo).methodTwo();

        //call the method to be tested
        SampleResponse sampleResponse = sample.methodOfSample() 

        //Assert
        <assert the SampleResponse here>
    }
}

Reference

A bit too late with this answer, but since I faced a similar question, I made a test with JMeter and a MySQL server on same machine, where I have used:

1. A transaction Controller (generating parent sample) that contained two JDBC Requests: a Delete and an Insert statement
2. A sepparate JDBC Request containing the Update statement.

After running the test for 500 loops, I have obtained the following results:

DEL + INSERT - Average: 62ms

Update - Average: 30ms

Results:

For me, the way it worked is I have to kill the parent process. Figure the parent process out and kill it

taskkill /IM "parent_process_name.exe" /T /F

No,No and No. Go and try the controller code below where we have the "LoadCustomer" overloaded.

public class CustomerController : Controller
    {
        //
        // GET: /Customer/

        public ActionResult LoadCustomer()
        {
            return Content("LoadCustomer");
        }
        public ActionResult LoadCustomer(string str)
        {
            return Content("LoadCustomer with a string");
        }
    }

If you try to invoke the "LoadCustomer" action you will get error as shown in the below figure.

Polymorphism is a part of C# programming while HTTP is a protocol. HTTP does not understand polymorphism. HTTP works on the concept's or URL and URL can only have unique name's. So HTTP does not implement polymorphism.

In order to fix the same we need to use "ActionName" attribute.

public class CustomerController : Controller
    {
        //
        // GET: /Customer/

        public ActionResult LoadCustomer()
        {
            return Content("LoadCustomer");
        }

        [ActionName("LoadCustomerbyName")]
        public ActionResult LoadCustomer(string str)
        {
            return Content("LoadCustomer with a string");
        }
    }

So now if you make a call to URL "Customer/LoadCustomer" the "LoadCustomer" action will be invoked and with URL structure "Customer/LoadCustomerByName" the "LoadCustomer(string str)" will be invoked.

The above answer i have taken from this codeproject article --> MVC Action overloading

Sometimes clear will not work. Use float: none as an override

BufferedReader#read reads single character[0 to 65535 (0x00-0xffff)] from the stream, so it is not possible to read single integer from stream.

            String s= inp.readLine();
            int[] m= new int[2];
            String[] s1 = inp.readLine().split(" ");
            m[0]=Integer.parseInt(s1[0]);
            m[1]=Integer.parseInt(s1[1]);

            // Checking whether I am taking the inputs correctly
            System.out.println(s);
            System.out.println(m[0]);
            System.out.println(m[1]);

You can check also Scanner vs. BufferedReader.

Another way is to call the dir() function (see https://docs.python.org/2/library/functions.html#dir).

a = Animal()
dir(a)   
>>>
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribute__',
 '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', 
 '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 
 '__weakref__', 'age', 'color', 'kids', 'legs', 'name', 'smell']

Note, that dir() tries to reach any attribute that is possible to reach.

Then you can access the attributes e.g. by filtering with double underscores:

attributes = [attr for attr in dir(a) 
              if not attr.startswith('__')]

This is just an example of what is possible to do with dir(), please check the other answers for proper way of doing this.

I've used SQL Delta before (http://www.sqldelta.com/), it's really good. Not free however, not sure how prices compare to Red-Gates

In PHP 5.3 or greater, you can get it like this:

$ip = getenv('HTTP_CLIENT_IP')?:
getenv('HTTP_X_FORWARDED_FOR')?:
getenv('HTTP_X_FORWARDED')?:
getenv('HTTP_FORWARDED_FOR')?:
getenv('HTTP_FORWARDED')?:
getenv('REMOTE_ADDR');

You have to use a relative path in the URL. I think you made two folders in the root directory where your index.html resides. One is 'CSS' folder & another is 'img' folder.

Now, if you have to access 'img' folder in css files. So you have to go back once in root directory using "../" syntax. Then move to the 'img' folder using "../img" syntax. Then write the image name "../img/debut_dark.png".

body { 
    background: url("../img/debut_dark.png") repeat 0 0;
}

If you don't need the code to be portable to old unices, you can use clock_gettime(), which will give you the time in nanoseconds (if your processor supports that resolution). It's POSIX, but from 2001.

You need the /g for global matching

replace(/\n/g, "<br />");

This works for me for \n - see this answer if you might have \r\n

NOTE: The dupe is the most complete answer for any combination of \r\n, \r or \n

var messagetoSend = document.getElementById('x').value.replace(/\n/g, "<br />");_x000D_
console.log(messagetoSend);

UPDATE

It seems some visitors of this question have text with the breaklines escaped as

some text\r\nover more than one line"

In that case you need to escape the slashes:

replace(/\\r\\n/g, "<br />");

NOTE: All browsers will ignore \r in a string when rendering.

What about this? Not as pretty but explicit.

orig_dict = {'a' : 1, 'b' : 2}
new_dict = {'a' : 2, 'v' : 'hello', 'b' : 2}

updates = {}
for k2, v2 in new_dict.items():
    if k2 in orig_dict:    
        if v2 != orig_dict[k2]:
            updates.update({k2 : v2})
    else:
        updates.update({k2 : v2})

#test it
#value of 'a' was changed
#'v' is a completely new entry
assert all(k in updates for k in ['a', 'v'])

You need to set the Identity seed to that value:

CREATE TABLE orders
(
 id int IDENTITY(9586,1)
)

To alter an existing table:

ALTER TABLE orders ALTER COLUMN Id INT IDENTITY (9586, 1);

More info on CREATE TABLE (Transact-SQL) IDENTITY (Property)

The real answer is: Because you cannot trust defer.

In concept, defer and async differ as follows:

async allows the script to be downloaded in the background without blocking. Then, the moment it finishes downloading, rendering is blocked and that script executes. Render resumes when the script has executed.

defer does the same thing, except claims to guarantee that scripts execute in the order they were specified on the page, and that they will be executed after the document has finished parsing. So, some scripts may finish downloading then sit and wait for scripts that downloaded later but appeared before them.

Unfortunately, due to what is really a standards cat fight, defer's definition varies spec to spec, and even in the most recent specs doesn't offer a useful guarantee. As answers here and this issue demonstrate, browsers implement defer differently:

• In certain situations some browsers have a bug that causes defer scripts to run out of order.
• Some browsers delay the DOMContentLoaded event until after the defer scripts have loaded, and some don't.
• Some browsers obey defer on <script> elements with inline code and without a src attribute, and some ignore it.

Fortunately the spec does at least specify that async overrides defer. So you can treat all scripts as async and get a wide swath of browser support like so:

<script defer async src="..."></script>

98% of browsers in use worldwide and 99% in the US will avoid blocking with this approach.

(If you need to wait until the document has finished parsing, listen to the event DOMContentLoaded event or use jQuery's handy .ready() function. You'd want to do this anyway to fall back gracefully on browsers that don't implement defer at all.)

This code in python, when called with allowed_characters set to [0,1] and 4 character max, would generate 2^4 results:

['0000', '0001', '0010', '0011', '0100', '0101', '0110', '0111', '1000', '1001', '1010', '1011', '1100', '1101', '1110', '1111']

def generate_permutations(chars = 4) :

#modify if in need!
    allowed_chars = [
        '0',
        '1',
    ]

    status = []
    for tmp in range(chars) :
        status.append(0)

    last_char = len(allowed_chars)

    rows = []
    for x in xrange(last_char ** chars) :
        rows.append("")
        for y in range(chars - 1 , -1, -1) :
            key = status[y]
            rows[x] = allowed_chars[key] + rows[x]

        for pos in range(chars - 1, -1, -1) :
            if(status[pos] == last_char - 1) :
                status[pos] = 0
            else :
                status[pos] += 1
                break;

    return rows

import sys


print generate_permutations()

Hope this is of use to you. Works with any character, not only numbers

Here we go:

Dimension imgSize = new Dimension(500, 100);
Dimension boundary = new Dimension(200, 200);

Function to return the new size depending on the boundary:

public static Dimension getScaledDimension(Dimension imgSize, Dimension boundary) {

    int original_width = imgSize.width;
    int original_height = imgSize.height;
    int bound_width = boundary.width;
    int bound_height = boundary.height;
    int new_width = original_width;
    int new_height = original_height;

    // first check if we need to scale width
    if (original_width > bound_width) {
        //scale width to fit
        new_width = bound_width;
        //scale height to maintain aspect ratio
        new_height = (new_width * original_height) / original_width;
    }

    // then check if we need to scale even with the new height
    if (new_height > bound_height) {
        //scale height to fit instead
        new_height = bound_height;
        //scale width to maintain aspect ratio
        new_width = (new_height * original_width) / original_height;
    }

    return new Dimension(new_width, new_height);
}

In case anyone also needs the image resizing code, here is a decent solution.

If you're unsure about the above solution, there are different ways to achieve the same result.

     import java.text.ParseException;
     import java.text.SimpleDateFormat;
     import java.util.Date;
     public class MyClass 
     {
     public static void main(String args[]) 
     {
     SimpleDateFormat formatter = new SimpleDateFormat("EEE MMM dd HH:mm:ss Z yyyy");

     String dateInString = "Wed Mar 14 15:30:00 EET 2018";

     SimpleDateFormat formatterOut = new SimpleDateFormat("dd MMM yyyy");


     try {

        Date date = formatter.parse(dateInString);
        System.out.println(date);
        System.out.println(formatterOut.format(date));

         } catch (ParseException e) {
        e.printStackTrace();
         }
    }
    }

here is your Date object date and the output is :

Wed Mar 14 13:30:00 UTC 2018

14 Mar 2018

Do it like this:

char s[256];
strcpy(s, "one two three");
char* token = strtok(s, " ");
while (token) {
    printf("token: %s\n", token);
    token = strtok(NULL, " ");
}

Note: strtok modifies the string its tokenising, so it cannot be a const char*.

You must check this: Docblock Comment standards

Putting together comments from a couple different answers here, in the Solr docs and on the other SO question, I found that the following syntax produces the correct result for my use case

(my_field=my_value or my_field is null):

(my_field:"my_value" OR (*:* NOT my_field:*))

This works for solr 4.1.0. This is slightly different than the use case in the OP; but, I thought that others would find it useful.

After chasing the Environment Variables preference pane and discovering that the link is broken and a search on Apple's site seems to indicate they've forgotten about it... I started back onto the trail of the elusive launchd process.

On my system (Mac OS X 10.6.8) it appears that variables defined in environment.plist are being reliably exported to apps launched from Spotlight (via launchd). My trouble is that those vars are not being exported to new bash sessions in Terminal. I.e. I have the opposite problem as portrayed here.

NOTE: environment.plist looks like JSON, not XML, as described previously

I was able to get Spotlight apps to see the vars by editing ~/MacOSX/environment.plist and I was able to force the same vars into a new Terminal session by adding the following to my .profile file:

eval $(launchctl export)

In JPA 2.0 if you want to delete an address if you removed it from a User entity you can add orphanRemoval=true (instead of CascadeType.REMOVE) to your @OneToMany.

More explanation between orphanRemoval=true and CascadeType.REMOVE is here.

The question doesn't address multiline strings, but here is how you would strip leading whitespace from a multiline string using python's standard library textwrap module. If we had a string like:

s = """
    line 1 has 4 leading spaces
    line 2 has 4 leading spaces
    line 3 has 4 leading spaces
"""

if we print(s) we would get output like:

>>> print(s)
    this has 4 leading spaces 1
    this has 4 leading spaces 2
    this has 4 leading spaces 3

and if we used textwrap.dedent:

>>> import textwrap
>>> print(textwrap.dedent(s))
this has 4 leading spaces 1
this has 4 leading spaces 2
this has 4 leading spaces 3

Ids are meant to be unique, and never use an id that starts with a number, use data-attributes instead to set the target like so :

<div id="searchbycharacter">
    <a class="searchbychar" href="#" data-target="numeric">0-9 |</a> 
    <a class="searchbychar" href="#" data-target="A"> A |</a> 
    <a class="searchbychar" href="#" data-target="B"> B |</a> 
    <a class="searchbychar" href="#" data-target="C"> C |</a> 
    ... Untill Z
</div>

As for the jquery :

$(document).on('click','.searchbychar', function(event) {
    event.preventDefault();
    var target = "#" + this.getAttribute('data-target');
    $('html, body').animate({
        scrollTop: $(target).offset().top
    }, 2000);
});

Zev Eisenberg's answer is simple and straightforward, but it does not always work, and it may fail with this warning message:

Warning: Attempt to present <UIAlertController: 0x7fe6fd951e10>  
 on <ThisViewController: 0x7fe6fb409480> which is already presenting 
 <AnotherViewController: 0x7fe6fd109c00>

This is because the windows rootViewController is not at the top of the presented views. To correct this we need to walk up the presentation chain, as shown in my UIAlertController extension code written in Swift 3:

   /// show the alert in a view controller if specified; otherwise show from window's root pree
func show(inViewController: UIViewController?) {
    if let vc = inViewController {
        vc.present(self, animated: true, completion: nil)
    } else {
        // find the root, then walk up the chain
        var viewController = UIApplication.shared.keyWindow?.rootViewController
        var presentedVC = viewController?.presentedViewController
        while presentedVC != nil {
            viewController = presentedVC
            presentedVC = viewController?.presentedViewController
        }
        // now we present
        viewController?.present(self, animated: true, completion: nil)
    }
}

func show() {
    show(inViewController: nil)
}

Updates on 9/15/2017:

Tested and confirmed that the above logic still works great in the newly available iOS 11 GM seed. The top voted method by agilityvision, however, does not: the alert view presented in a newly minted UIWindow is below the keyboard and potentially prevents the user from tapping its buttons. This is because in iOS 11 all windowLevels higher than that of keyboard window is lowered to a level below it.

One artifact of presenting from keyWindow though is the animation of keyboard sliding down when alert is presented, and sliding up again when alert is dismissed. If you want the keyboard to stay there during presentation, you can try to present from the top window itself, as shown in below code:

func show(inViewController: UIViewController?) {
    if let vc = inViewController {
        vc.present(self, animated: true, completion: nil)
    } else {
        // get a "solid" window with the highest level
        let alertWindow = UIApplication.shared.windows.filter { $0.tintColor != nil || $0.className() == "UIRemoteKeyboardWindow" }.sorted(by: { (w1, w2) -> Bool in
            return w1.windowLevel < w2.windowLevel
        }).last
        // save the top window's tint color
        let savedTintColor = alertWindow?.tintColor
        alertWindow?.tintColor = UIApplication.shared.keyWindow?.tintColor

        // walk up the presentation tree
        var viewController = alertWindow?.rootViewController
        while viewController?.presentedViewController != nil {
            viewController = viewController?.presentedViewController
        }

        viewController?.present(self, animated: true, completion: nil)
        // restore the top window's tint color
        if let tintColor = savedTintColor {
            alertWindow?.tintColor = tintColor
        }
    }
}

The only not so great part of the above code is that it checks the class name UIRemoteKeyboardWindow to make sure we can include it too. Nevertheless the above code does work great in iOS 9, 10 and 11 GM seed, with the right tint color and without the keyboard sliding artifacts.

I have come across AXTools CODESMART..Try that once. Use code analyzer in reviews section.It will list dead local and global functions along with other issues.

Add !importent in your css

* {
   font-size: 16px !importent;
   line-height: 2;
}

Do a describe on dba_arguments, dba_errors, dba_procedures, dba_objects, dba_source, dba_object_size. Each of these has part of the pictures for looking at the procedures and functions.

Also the object_type in dba_objects for packages is 'PACKAGE' for the definition and 'PACKAGE BODY" for the body.

If you are comparing schemas on the same database then try:

select * from dba_objects 
   where schema_name = 'ASCHEMA' 
     and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )
minus
select * from dba_objects 
where schema_name = 'BSCHEMA' 
  and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )

and switch around the orders of ASCHEMA and BSCHEMA.

If you also need to look at triggers and comparing other stuff between the schemas you should take a look at the Article on Ask Tom about comparing schemas

Joking aside, if you're only expecting your input integer to be a zero or a one, you should really be checking that this is the case.

int yourInteger = whatever;
bool yourBool;
switch (yourInteger)
{
    case 0: yourBool = false; break;
    case 1: yourBool = true;  break;
    default:
        throw new InvalidOperationException("Integer value is not valid");
}

The out-of-the-box Convert won't check this; nor will yourInteger (==|!=) (0|1).

Swift 3 UIImage extension:

func fixOrientation() -> UIImage {

    // No-op if the orientation is already correct
    if ( self.imageOrientation == .up ) {
        return self;
    }

    // We need to calculate the proper transformation to make the image upright.
    // We do it in 2 steps: Rotate if Left/Right/Down, and then flip if Mirrored.
    var transform: CGAffineTransform = .identity

    if ( self.imageOrientation == .down || self.imageOrientation == .downMirrored ) {
        transform = transform.translatedBy(x: self.size.width, y: self.size.height)
        transform = transform.rotated(by: .pi)
    }

    if ( self.imageOrientation == .left || self.imageOrientation == .leftMirrored ) {
        transform = transform.translatedBy(x: self.size.width, y: 0)
        transform = transform.rotated(by: .pi/2)
    }

    if ( self.imageOrientation == .right || self.imageOrientation == .rightMirrored ) {
        transform = transform.translatedBy(x: 0, y: self.size.height);
        transform = transform.rotated(by: -.pi/2);
    }

    if ( self.imageOrientation == .upMirrored || self.imageOrientation == .downMirrored ) {
        transform = transform.translatedBy(x: self.size.width, y: 0)
        transform = transform.scaledBy(x: -1, y: 1)
    }

    if ( self.imageOrientation == .leftMirrored || self.imageOrientation == .rightMirrored ) {
        transform = transform.translatedBy(x: self.size.height, y: 0);
        transform = transform.scaledBy(x: -1, y: 1);
    }

    // Now we draw the underlying CGImage into a new context, applying the transform
    // calculated above.
    let ctx: CGContext = CGContext(data: nil, width: Int(self.size.width), height: Int(self.size.height),
                                   bitsPerComponent: self.cgImage!.bitsPerComponent, bytesPerRow: 0,
                                   space: self.cgImage!.colorSpace!,
                                   bitmapInfo: self.cgImage!.bitmapInfo.rawValue)!;

    ctx.concatenate(transform)

    if ( self.imageOrientation == .left ||
        self.imageOrientation == .leftMirrored ||
        self.imageOrientation == .right ||
        self.imageOrientation == .rightMirrored ) {
        ctx.draw(self.cgImage!, in: CGRect(x: 0.0,y: 0.0,width: self.size.height,height: self.size.width))
    } else {
        ctx.draw(self.cgImage!, in: CGRect(x: 0.0,y: 0.0,width: self.size.width,height: self.size.height))
    }

    // And now we just create a new UIImage from the drawing context and return it
    return UIImage(cgImage: ctx.makeImage()!)
}

You need to grant SELECT permissions to the MySQL user who is connecting to MySQL

same question as here Error: select command denied to user '<userid>'@'<ip-address>' for table '<table-name>'

see answers of the link ;)

you can use this syntax to redirect all output stderr and stdout to stdout.txt

<cmd> <args> > allout.txt 2>&1 

you do this in the SSMS app, not the SQL. In the toolbar select

Query --> Results To --> Results To File

This was critical to get this to work with Entity Framework:

var genericCollection = list as ICollection<T>;

if (genericCollection != null)
{
   //your code 
}

If you do not use DockerFile, you can simply add permission as command line argument of the bash:

docker run -t <image>  /bin/bash -c "chmod +x /usr/src/app/docker-entrypoint.sh; /usr/src/app/docker-entrypoint.sh"

As Shafik already wrote you need to use the right format because scanf gets you a char. Don't hesitate to look here if u aren't sure about the usage: http://www.cplusplus.com/reference/cstdio/printf/

Hint: It's faster/nicer to write x=x+1; the shorter way: x++;

Sorry for answering what's answered just wanted to give him the link - the site was really useful to me all the time dealing with C.

Looks like the data has the same columns, so you can:

df1 = pd.DataFrame(data1)
df2 = pd.DataFrame(data2)

merged_df = pd.concat([df1, df2])

This is what I use to make it dropdown on hover with some jQuery

$(document).ready(function () {
    $('.navbar-default .navbar-nav > li.dropdown').hover(function () {
        $('ul.dropdown-menu', this).stop(true, true).slideDown('fast');
        $(this).addClass('open');
    }, function () {
        $('ul.dropdown-menu', this).stop(true, true).slideUp('fast');
        $(this).removeClass('open');
    });
});

    cout << "\n4 ";
    x += testpow<4>(rand(), loops);
    x += test4(rand(), loops);

    cout << "\n5 ";
    x += testpow<5>(rand(), loops);
    x += test5(rand(), loops);
    cout << "\n" << x << "\n";
}

Results are:

1 00:00:01.126008 00:00:01.128338 
2 00:00:01.125832 00:00:01.127227

Note that I accumulate the result of every pow calculation to make sure the compiler doesn't optimize it away.

If I use the std::pow(double, double) version, and loops = 1000000l, I get:

1 00:00:00.011339 00:00:00.011262

This is on an Intel Core Duo running Ubuntu 9.10 64bit. Compiled using gcc 4.4.1 with -o2 optimization.

So in C, yes x*x*x will be faster than pow(x, 3), because there is no pow(double, int) overload. In C++, it will be the roughly same. (Assuming the methodology in my testing is correct.)

This is in response to the comment made by An Markm:

Even if a using namespace std directive was issued, if the second parameter to pow is an int, then the std::pow(double, int) overload from <cmath> will be called instead of ::pow(double, double) from <math.h>.

This test code confirms that behavior:

#include <iostream>

namespace foo
{

    double bar(double x, int i)
    {
        std::cout << "foo::bar\n";
        return x*i;
    }


}

double bar(double x, double y)
{
    std::cout << "::bar\n";
    return x*y;
}

using namespace foo;

int main()
{
    double a = bar(1.2, 3); // Prints "foo::bar"
    std::cout << a << "\n";
    return 0;
}

I do this to make sure they remember to print landscape, which is necessary for a lot of pages on a lot of printers.

<a href="javascript:alert('Please be sure to set your printer to Landscape.');window.print();">Print Me...</a>

or

<body onload="alert('Please be sure to set your printer to Landscape.');window.print();">
etc.
</body>

The following code works if you use jquery

$( "object" ).replaceWith('<object data="http://www.google.com"></object>');

I added -adaptive-resize 60% to the suggested command, but with -quality 60%.

convert -strip -interlace Plane -gaussian-blur 0.05 -quality 60% -adaptive-resize 60% img_original.jpg img_resize.jpg

These were my results

• img_original.jpg = 13,913KB
• img_resized.jpg = 845KB

I'm not sure if that conversion destroys my image too much, but I honestly didn't think my conversion looked like crap. It was a wide angle panorama and I didn't care for meticulous obstruction.

Wrap your all statements in !IsPostBack condition on page load.

protected void Page_Load(object sender, EventArgs e)
{
   if(!IsPostBack)
   {
      // all statements
   }
}

This will fix your issue.

return RedirectToAction("ProductImageManager","Index", new   { id=id   });

The only way that I was able to get the column names was using the following query:

select COLUMN_NAME
FROM all_tab_columns atc
WHERE table_name like 'USERS'

I tried the existing answers to this question, and none of them worked on Chrome for me. What did work was slightly different:

$('body, html, #containerDiv').scrollTop(0);

Many in the community would prefer no limit with warnings about performance, see this comment for a well reasoned argument: https://jira.mongodb.org/browse/SERVER-431?focusedCommentId=22283&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-22283

My take, the lead developers are stubborn about this issue because they decided it was an important "feature" early on. They're not going to change it anytime soon because their feelings are hurt that anyone questioned it. Another example of personality and politics detracting from a product in open source communities but this is not really a crippling issue.

You also need to change the DataSource of the connection string. KELVIN-PC is the name of your local machine and the sql server is running on the default instance.

If you are sure the the server is running as the default instance, you can always use . in the DataSource, eg.

connectionString="Data Source=.;Initial Catalog=LMS;User ID=sa;Password=temperament"

otherwise, you need to specify the name of the instance of the server,

connectionString="Data Source=.\INSTANCENAME;Initial Catalog=LMS;User ID=sa;Password=temperament"

To find the duplicate values only :

var duplicates = list.GroupBy(x => x.Key).Any(g => g.Count() > 1);

E.g.

var list = new[] {1,2,3,1,4,2};

GroupBy will group the numbers by their keys and will maintain the count (number of times it repeated) with it. After that, we are just checking the values who have repeated more than once.

To find the unique values only :

var unique = list.GroupBy(x => x.Key).All(g => g.Count() == 1);

E.g.

var list = new[] {1,2,3,1,4,2};

GroupBy will group the numbers by their keys and will maintain the count (number of times it repeated) with it. After that, we are just checking the values who have repeated only once means are unique.

I'd strongly recommend to keep working with swap files (in case Vim crashes).

You can set the directory where the swap files are stored, so they don't clutter your normal directories:

set swapfile
set dir=~/tmp

See also

:help swap-file

Do you want to wait for them to finish? If so, use the Join method.

There is also the isAlive property if you just want to check it.

Java programming language enums are far more powerful than their counterparts in other languages, which are little more than glorified integers. The new enum declaration defines a full-fledged class (dubbed an enum type). In addition to solving all the problems(Not typesafe, No namespace, Brittleness and Printed values are uninformative) that exists with following int Enum pattern which was used prior to java 5.0 :

public static final int SEASON_WINTER = 0;

it also allows you to add arbitrary methods and fields to an enum type, to implement arbitrary interfaces, and more. Enum types provide high-quality implementations of all the Object methods. They are Comparable and Serializable, and the serial form is designed to withstand arbitrary changes in the enum type. You can also use Enum in switch case.

Read the full article on Java Enums http://docs.oracle.com/javase/1.5.0/docs/guide/language/enums.html for more details.

 $dob = $this->dateOfBirth; //Datetime 
        $currentDate = new \DateTime();
        $dateDiff = $dob->diff($currentDate);
        $years = $dateDiff->y;
        $months = $dateDiff->m;
        $days = $dateDiff->d;
        $age = $years .' Year(s)';

        if($years === 0) {
            $age = $months .' Month(s)';
            if($months === 0) {
                $age = $days .' Day(s)';
            }
        }
        return $age;

What I'm guessing is that you need to set those input elements to runat="server".

So you won't be able to access the control

<input type="text" name="email" id="myTextBox" />

But you'll be able to work with

<input type="text" name="email" id="myTextBox" runat="server" />

And read from it by using

string myStringFromTheInput = myTextBox.Value;

Perm space is used to keep informations for loaded classes and few other advanced features like String Pool(for highly optimized string equality testing), which usually get created by String.intern() methods. As your application(number of classes) will grow this space shall get filled quickly, since the garbage collection on this Space is not much effective to clean up as required, you quickly get Out of Memory : perm gen space error. After then, no application shall run on that machine effectively even after having a huge empty JVM.

Before starting your application you should java -XX:MaxPermSize to get rid of this error.

newList = [oldList[3]]
newList.extend(oldList[:3])
newList.extend(oldList[4:])

For anyone attempting to compile code from an external source that uses an automated build utility such as Make, to avoid having to track down the explicit gcc compilation calls you can set an environment variable. Enter on command prompt or put in .bashrc (or .bash_profile on Mac):

export CFLAGS="-std=c99"

Note that a similar solution applies if you run into a similar scenario with C++ compilation that requires C++ 11, you can use:

export CXXFLAGS="-std=c++11"

Servlet to be accessible from a browser, then must tell the servlet container what servlets to deploy, and what URL's to map the servlets to. This is done in the web.xml file of your Java web application.

use web.xml in servlet

<servlet>
    <description></description>
    <display-name>servlet class name</display-name>
    <servlet-name>servlet class name</servlet-name>
    <servlet-class>servlet package name/servlet class name</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>servlet class name</servlet-name>
    <url-pattern>/servlet class name</url-pattern>
</servlet-mapping>

manly use web.xml for servlet mapping.

if ! test -f $PIDFILE || ! psgrep `cat $PIDFILE`; then
    restart_process
    # Write PIDFILE
    echo $! >$PIDFILE
fi

var x = 1234567;

x.toString().length;

This process will also work forFloat Number and for Exponential number also.

This works for me:

URL url = new URL("http://upload.wikimedia.org/wikipedia/commons/9/9c/Image-Porkeri_001.jpg");
InputStream in = new BufferedInputStream(url.openStream());
OutputStream out = new BufferedOutputStream(new FileOutputStream("Image-Porkeri_001.jpg"));

for ( int i; (i = in.read()) != -1; ) {
    out.write(i);
}
in.close();
out.close();

You don't need CSS for this.

     <img src="abc"/>

now with link:

     <a href="#myLink"><img src="abc"/></a>

Or with jquery, later on, you can use the wrap property, see these questions answer:

how to add a link to an image using jquery?

Pretty Late answer though. But This has worked for me , and could be useful.

While Using Spring Security ans mockMvc, all you need to is use @WithMockUser annotation like others are mentioned.

Spring security also provides another annotation called @WithAnonymousUser for testing unauthenticated requests. However you should be careful here. You would be expecting 401, but I got 403 Forbidden Error by default. In actual scenarios, when you are running actual service, It is redirected and you end up getting the correct 401 response code.Use this annotation for anonymous requests.

You may also think of ommitting the annotaions and simply keep it unauthorized. But this usually raises the correct exceptions(like AuthenticationException), but you will get correct status code if it is handled correctly(If you are using custom handler). I used to get 500 for this. So look for the exceptions raised in the debugger, and check if it is handled rightly and returns the correct status code.

long second = TimeUnit.MILLISECONDS.toSeconds(millis);
long minute = TimeUnit.MILLISECONDS.toMinutes(millis);
long hour = TimeUnit.MILLISECONDS.toHours(millis);
millis -= TimeUnit.SECONDS.toMillis(second);
return String.format("%02d:%02d:%02d:%d", hour, minute, second, millis);

You can add a filter for the nav_menu_css_class action in your functions.php file.

Example:

function atg_menu_classes($classes, $item, $args) {
  if($args->theme_location == 'secondary') {
    $classes[] = 'list-inline-item';
  }
  return $classes;
}
add_filter('nav_menu_css_class', 'atg_menu_classes', 1, 3);

Docs: https://developer.wordpress.org/reference/hooks/nav_menu_css_class/

Yes, use getJSONP. It's the only way to make cross domain/server async calls. (*Or it will be in the near future). Something like

$.getJSON('your-api-url/validate.php?'+$(this).serialize+'callback=?', function(data){
if(data)console.log(data);
});

The callback parameter will be filled in automatically by the browser, so don't worry.

On the server side ('validate.php') you would have something like this

<?php
if(isset($_GET))
{
//if condition is met
echo $_GET['callback'] . '(' . "{'message' : 'success', 'userID':'69', 'serial' : 'XYZ99UAUGDVD&orwhatever'}". ')';
}
else echo json_encode(array('error'=>'failed'));
?>

Solutions above didn't work. It simply displayed the last key/value pairs, but this did:

http://localhost/?key[]=1&key[]=2

Returns:

Array
(
[key] => Array
    (
        [0] => 1
        [1] => 2
    )

The reason the encoded array is longer by about a quarter is that base-64 encoding uses only six bits out of every byte; that is its reason of existence - to encode arbitrary data, possibly with zeros and other non-printable characters, in a way suitable for exchange through ASCII-only channels, such as e-mail.

The way you get your original array back is by using Convert.FromBase64String:

 byte[] temp_backToBytes = Convert.FromBase64String(temp_inBase64);

I am new to Rust, but this solution seems to work:

#[macro_use]
extern crate lazy_static;

use std::sync::{Arc, Mutex};

lazy_static! {
    static ref GLOBAL: Arc<Mutex<GlobalType> =
        Arc::new(Mutex::new(GlobalType::new()));
}

Another solution is to declare a crossbeam channel tx/rx pair as an immutable global variable. The channel should be bounded and can only hold 1 element. When you initialize the global variable, push the global instance into the channel. When using the global variable, pop the channel to acquire it and push it back when done using it.

Both solutions should provide a safe approach to using global variables.

try this:

$("table#myTable tr").last().after(data);

Set button visibility to GONE (button will be completely "removed" -- the buttons space will be available for another widgets) or INVISIBLE (button will became "transparent" -- its space will not be available for another widgets):

View b = findViewById(R.id.button);
b.setVisibility(View.GONE);

or in xml:

<Button ... android:visibility="gone"/>

Does your images have exactly a 460px width as the span6 ? In my case, with different image sizes, I put a height attribute on my images to be sure they are all the same height and the carousel don't resize between images.

In your case, try to set a height so the ratio between this height and the width of your carousel-inner div is the same as the aspectRatio of your images

I know you've found another solution, but for those like me who find this question, looking for the same thing, it can be achieved with requests as follows:

Firstly, as Marcus did, check the source of the login form to get three pieces of information - the url that the form posts to, and the name attributes of the username and password fields. In his example, they are inUserName and inUserPass.

Once you've got that, you can use a requests.Session() instance to make a post request to the login url with your login details as a payload. Making requests from a session instance is essentially the same as using requests normally, it simply adds persistence, allowing you to store and use cookies etc.

Assuming your login attempt was successful, you can simply use the session instance to make further requests to the site. The cookie that identifies you will be used to authorise the requests.

Example

import requests

# Fill in your details here to be posted to the login form.
payload = {
    'inUserName': 'username',
    'inUserPass': 'password'
}

# Use 'with' to ensure the session context is closed after use.
with requests.Session() as s:
    p = s.post('LOGIN_URL', data=payload)
    # print the html returned or something more intelligent to see if it's a successful login page.
    print p.text

    # An authorised request.
    r = s.get('A protected web page url')
    print r.text
        # etc...

Here is a solution using for of and continue instead of forEach:

let elementsCollection = SomeElements.find();

for (let el of elementsCollection) {

    // continue will exit out of the current 
    // iteration and continue on to the next
    if (!el.shouldBeProcessed){
        continue;
    }

    doSomeLengthyOperation();

});

This may be a bit more useful if you need to use asynchronous functions inside your loop which do not work inside forEach. For example:

(async fuction(){

for (let el of elementsCollection) {

    if (!el.shouldBeProcessed){
        continue;
    }

    let res;

    try {
        res = await doSomeLengthyAsyncOperation();
    } catch (err) {
        return Promise.reject(err)
    }

});

})()

You can use find_all in the following way to find every a element that has an href attribute, and print each one:

from BeautifulSoup import BeautifulSoup

html = '''<a href="some_url">next</a>
<span class="class"><a href="another_url">later</a></span>'''

soup = BeautifulSoup(html)

for a in soup.find_all('a', href=True):
    print "Found the URL:", a['href']

The output would be:

Found the URL: some_url
Found the URL: another_url

Note that if you're using an older version of BeautifulSoup (before version 4) the name of this method is findAll. In version 4, BeautifulSoup's method names were changed to be PEP 8 compliant, so you should use find_all instead.

If you want all tags with an href, you can omit the name parameter:

href_tags = soup.find_all(href=True)

I'm too late here but like to extend Daniel's answer about using aws cli to include filter expression.

Running

aws dynamodb scan \
    --table-name <tableName> \
    --filter-expression "#v = :num" \
    --expression-attribute-names '{"#v": "fieldName"}' \
    --expression-attribute-values '{":num": {"N": "123"}}' \
    --select "COUNT"

would give

{
    "Count": 2945,
    "ScannedCount": 7874,
    "ConsumedCapacity": null
}

That is, ScannedCount is total count and Count is the number of items which are filtered by given expression (fieldName=123).

Just check the length of files property, which is a FileList object contained on the input element

if( document.getElementById("videoUploadFile").files.length == 0 ){
    console.log("no files selected");
}

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

Take Inputs from User and Insertion Sort. Here is how it works:

package com.learning.constructor;

import java.util.Scanner;



public class InsertionSortArray {

public static void main(String[] args) {    

Scanner s=new Scanner(System.in);

System.out.println("enter number of elements");

int n=s.nextInt();


int arr[]=new int[n];

System.out.println("enter elements");

for(int i=0;i<n;i++){//for reading array
    arr[i]=s.nextInt();

}

System.out.print("Your Array Is: ");
//for(int i: arr){ //for printing array
for (int i = 0; i < arr.length; i++){
    System.out.print(arr[i] + ",");

}
System.out.println("\n");        

    int[] input = arr;
    insertionSort(input);
}

private static void printNumbers(int[] input) {

    for (int i = 0; i < input.length; i++) {
        System.out.print(input[i] + ", ");
    }
    System.out.println("\n");
}

public static void insertionSort(int array[]) {
    int n = array.length;
    for (int j = 1; j < n; j++) {
        int key = array[j];
        int i = j-1;
        while ( (i > -1) && ( array [i] > key ) ) {
            array [i+1] = array [i];
            i--;
        }
        array[i+1] = key;
        printNumbers(array);
    }
}

}

This works CONVERT(VARCHAR(100), CONVERT(DECIMAL(30, 15), fieldname))

Try This

Just go to your Manifest file. and You have define the label for each activity in your manifest file.

<activity
        android:name=".Search_Video"
        android:label="@string/app_name"
        android:screenOrientation="portrait">
    </activity>

here change

android:label="@string/your_title"

Since I found I was doing this in several places in my app, I wrapped it in a plugin:

(function ($) {
   $.fn.dialogNoClose = function () {
      return this.each(function () {
         // hide the close button and prevent ESC key from closing
         $(this).closest(".ui-dialog").find(".ui-dialog-titlebar-close").hide();
         $(this).dialog("option", "closeOnEscape", false);
      });
   };
})(jQuery)

Usage Example:

$("#dialog").dialog({ /* lots of options */ }).dialogNoClose();

Did you tried to start from right to left by using the rev command ? In this case you just need to print the 2nd column:

The first thing to do would probably be to replace every mysql_* function call with its equivalent mysqli_*, at least if you are willing to use the procedural API -- which would be the easier way, considering you already have some code based on the MySQL API, which is a procedural one.

To help with that, the MySQLi Extension Function Summary is definitely something that will prove helpful.

For instance:

• mysql_connect will be replaced by mysqli_connect
• mysql_error will be replaced by mysqli_error and/or mysqli_connect_error, depending on the context
• mysql_query will be replaced by mysqli_query
• and so on

Note: For some functions, you may need to check the parameters carefully: Maybe there are some differences here and there -- but not that many, I'd say: both mysql and mysqli are based on the same library (libmysql ; at least for PHP <= 5.2)

For instance:

• with mysql, you have to use the mysql_select_db once connected, to indicate on which database you want to do your queries
• mysqli, on the other side, allows you to specify that database name as the fourth parameter to mysqli_connect.
• Still, there is also a mysqli_select_db function that you can use, if you prefer.

At First click on preferences(Ctrl+Shift+alt+p) then click the option of syntax coloring and change the scheme to "Monokai".Now apply it and you will get the dark scheme.

Steps to start a certain local MongoDB instance and to connect to in from NodeJS app:

1. Create mongod.cfg for a new database using the path C:\Program Files\MongoDB\Server\4.0\mongod.cfg with the content

   systemLog:
     destination: file
     path: C:\Program Files\MongoDB\Server\4.0\log\mongod.log
   storage:
     dbPath: C:\Program Files\MongoDB\Server\4.0\data\db
   

2. Install mongoDB database by running

   mongod.exe --config "C:\Program Files\MongoDB\Server\4.0\mongod.cfg" --install

3. Run a particular mongoDB database

   mongod.exe --config "C:\Program Files\MongoDB\Server\4.0\mongod.cfg"

4. Run mongoDB service

   mongo 127.0.0.1:27017/db
   

   and !see mongoDB actual connection string to coonect to the service from NodeJS app

   MongoDB shell version v4.0.9
   connecting to: mongodb://127.0.0.1:27017/db?gssapiServiceName=mongodb
   Implicit session: session { "id" : UUID("c7ed5ab4-c64e-4bb8-aad0-ab4736406c03") }
   MongoDB server version: 4.0.9
   Server has startup warnings:

For Windows,

You cannot capture packets for Local Loopback in Wireshark however, you can use a very tiny but useful program called RawCap;

RawCap

Run RawCap on command prompt and select the Loopback Pseudo-Interface (127.0.0.1) then just write the name of the packet capture file (.pcap)

A simple demo is as below;

C:\Users\Levent\Desktop\rawcap>rawcap
Interfaces:
 0.     169.254.125.51  Local Area Connection* 12       Wireless80211
 1.     192.168.2.254   Wi-Fi   Wireless80211
 2.     169.254.214.165 Ethernet        Ethernet
 3.     192.168.56.1    VirtualBox Host-Only Network    Ethernet
 4.     127.0.0.1       Loopback Pseudo-Interface 1     Loopback
Select interface to sniff [default '0']: 4
Output path or filename [default 'dumpfile.pcap']: test.pcap
Sniffing IP : 127.0.0.1
File        : test.pcap
