All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if to bind them all together in the way I believe you intend.

Change <?php echo $proxy ?> to ' . $proxy . '.

You use <?php when you're outputting HTML by leaving PHP mode with ?>. When you using echo, you have to use concatenation, or wrap your string in double quotes and use interpolation.

We experienced this problem on pages with long Base64 strings. The problem occurs because we use CloudFlare.

Details: https://community.cloudflare.com/t/err-http2-protocol-error/119619.

Key section from the forum post:

After further testing on Incognito tabs on multiple browsers, then doing the changes on the code from a BASE64 to a real .png image, the issue never happened again, in ANY browser. The .png had around 500kb before becoming a base64,so CloudFlare has issues with huge lines of text on same line (since base64 is a long string) as a proxy between the domain and the heroku. As mentioned before, directly hitting Heroku url also never happened the issue.

The temporary hack is to disable HTTP/2 on CloudFlare.

Hope someone else can produce a better solution that doesn't require disabling HTTP/2 on CloudFlare.

your server should enable the cross origin requests, not the client. To do this, you can check this nice page with implementations and configurations for multiple platforms

Use like below:

  yourFunc(input: any):Observable<string> {
var requestHeader = { headers: new HttpHeaders({ 'Content-Type': 'text/plain', 'No-Auth': 'False' })};
const headers = new HttpHeaders().set('Content-Type', 'text/plain; charset=utf-8');
return this.http.post<string>(this.yourBaseApi+ '/do-api', input, { headers, responseType: 'text' as 'json'  });

}

I think many people have problems with Post 'Content-type': 'application / json' The problem here is parse data Map <String, dynamic> to json:

Hope the code below can help someone

Model:

class ConversationReq {
  String name = '';
  String description = '';
  String privacy = '';
  String type = '';
  String status = '';

  String role;
  List<String> members;
  String conversationType = '';

  ConversationReq({this.type, this.name, this.status, this.description, this.privacy, this.conversationType, this.role, this.members});

  Map<String, dynamic> toJson() {

    final Map<String, dynamic> data = new Map<String, dynamic>();

    data['name'] = this.name;
    data['description'] = this.description;
    data['privacy'] = this.privacy;
    data['type'] = this.type;

    data['conversations'] = [
      {
        "members": members,
        "conversationType": conversationType,
      }
    ];

    return data;
  }
}

Request:

createNewConversation(ConversationReq param) async {
    HeaderRequestAuth headerAuth = await getAuthHeader();
    var headerRequest = headerAuth.toJson();
/*
{
            'Content-type': 'application/json',
            'x-credential-session-token': xSectionToken,
            'x-user-org-uuid': xOrg,
          }
*/

    var bodyValue = param.toJson();

    var bodydata = json.encode(bodyValue);// important
    print(bodydata);

    final response = await http.post(env.BASE_API_URL + "xxx", headers: headerRequest, body: bodydata);

    print(json.decode(response.body));
    if (response.statusCode == 200) {
      // TODO
    } else {
      // If that response was not OK, throw an error.
      throw Exception('Failed to load ConversationRepo');
    }
  }

I know this is a little late, nevertheless i'm answering this for anyone still experiencing this issue on windows (USING XAMPP).

Step 1. Verify that there is a mismatch in your PHP version. To do this, open routes/web.php and create a simple route to return the php information like so:

Route::get('/', function() {
   return response()->json([
    'stuff' => phpinfo()
   ]);
})

and compare this with output from your command line

As we can see, in my case there is a mismatch, this usually happens if you have multiple versions of php installed.

Step 2. Add the php version being used by your xampp to your system path

Step 3. Verify that you have the extension enabled in your php.ini file. NB. Make sure you are editing the php.ini file that is shown under the 'loaded configuration file' entry in the results of phpinfo() command.

For express, upgrade your express library to 4.17.1 which is the latest stable version. Then;

In CorsOption: Set origin to your localhost url or your frontend production url and credentials to true e.g

  const corsOptions = {
    origin: config.get("origin"),
    credentials: true,
  };

I set my origin dynamically using config npm module.

Then , in res.cookie:

For localhost: you do not need to set sameSite and secure option at all, you can set httpOnly to true for http cookie to prevent XSS attack and other useful options depending on your use case.

For production environment, you need to set sameSite to none for cross-origin request and secure to true. Remember sameSite works with express latest version only as at now and latest chrome version only set cookie over https, thus the need for secure option.

Here is how I made mine dynamic

 res
    .cookie("access_token", token, {
      httpOnly: true,
      sameSite: app.get("env") === "development" ? true : "none",
      secure: app.get("env") === "development" ? false : true,
    })

As it turns out, one should not forget to include jacson dependency into the pom file. This solved the issue for me:

<dependency>
    <groupId>com.fasterxml.jackson.module</groupId>
    <artifactId>jackson-module-parameter-names</artifactId>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jdk8</artifactId>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
</dependency>

Give the same name in urls.py

 path('detail/<int:id>', views.detail, name="detail"),

Angular 8 HttpClient Service example with Error Handling and Custom Header

    import { Injectable } from '@angular/core';
    import { HttpClient, HttpHeaders, HttpErrorResponse } from '@angular/common/http';
    import { Student } from '../model/student';
    import { Observable, throwError } from 'rxjs';
    import { retry, catchError } from 'rxjs/operators';

    @Injectable({
      providedIn: 'root'
    })
    export class ApiService {

      // API path
      base_path = 'http://localhost:3000/students';

      constructor(private http: HttpClient) { }

      // Http Options
      httpOptions = {

      // Handle API errors
      handleError(error: HttpErrorResponse) {
        if (error.error instanceof ErrorEvent) {
          // A client-side or network error occurred. Handle it accordingly.
          console.error('An error occurred:', error.error.message);
        } else {

          )
      }

      ....
      ....

Check complete example tutorial here

Use a custom Action/Controller Attribute to set the CORS headers.

Example:

public class AllowMyRequestsAttribute : ControllerAttribute, IActionFilter
{
    public void OnActionExecuted(ActionExecutedContext context)
    {
        // check origin
        var origin = context.HttpContext.Request.Headers["origin"].FirstOrDefault();
        if (origin == someValidOrigin)
        {
            context.HttpContext.Response.Headers.Add("Access-Control-Allow-Origin", origin);
            context.HttpContext.Response.Headers.Add("Access-Control-Allow-Credentials", "true");
            context.HttpContext.Response.Headers.Add("Access-Control-Allow-Headers", "*");
            context.HttpContext.Response.Headers.Add("Access-Control-Allow-Methods", "*");
            // Add whatever CORS Headers you need.
        }
    }

    public void OnActionExecuting(ActionExecutingContext context)
    {
        // empty
    }
}

Then on the Web API Controller / Action:

[ApiController]
[AllowMyRequests]
public class MyController : ApiController
{
    [HttpGet]
    public ActionResult<string> Get()
    {
        return "Hello World";
    }
}

I was trying to use Feign, while I encounter same issue, As I understood HTTP message converter will help but wanted to understand how to achieve this.

@FeignClient(name = "mobilesearch", url = "${mobile.search.uri}" ,
        fallbackFactory = MobileSearchFallbackFactory.class,
        configuration = MobileSearchFeignConfig.class)
public interface MobileSearchClient {

    @RequestMapping(method = RequestMethod.GET)
    List<MobileSearchResponse> getPhones();
}

You have to use Customer Configuration for the decoder, MobileSearchFeignConfig,

public class MobileSearchFeignConfig {

    @Bean
    Logger.Level feignLoggerLevel() {
        return Logger.Level.FULL;
    }


    @Bean
    public Decoder feignDecoder() {
        return new ResponseEntityDecoder(new SpringDecoder(feignHttpMessageConverter()));
    }

    public ObjectFactory<HttpMessageConverters> feignHttpMessageConverter() {
        final HttpMessageConverters httpMessageConverters = new HttpMessageConverters(new MappingJackson2HttpMessageConverter());
        return new ObjectFactory<HttpMessageConverters>() {
            @Override
            public HttpMessageConverters getObject() throws BeansException {
                return httpMessageConverters;
            }
        };
    }

    public class MappingJackson2HttpMessageConverter extends org.springframework.http.converter.json.MappingJackson2HttpMessageConverter {
        MappingJackson2HttpMessageConverter() {
            List<MediaType> mediaTypes = new ArrayList<>();
            mediaTypes.add(MediaType.valueOf(MediaType.TEXT_HTML_VALUE + ";charset=UTF-8"));
            setSupportedMediaTypes(mediaTypes);
        }
    }

}

My case was that i was using RDS (mysql db verion 8) of AWS and was connecting my application through EC2 (my php code 5.6 was in EC2).

Here in this case since it is RDS there is no my.cnf the parameters are maintained by PARAMETER Group of AWS. Refer: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_WorkingWithParamGroups.html

so what i did was:

1. Created a new Parameter group and then edited them.

2. Searched all character-set parameters. These are blank by default. edit them individually and select utf8 from drop down list.

character_set_client, character_set_connection, character_set_database, character_set_server

3. SAVE

And then most important, Rebooted RDS instance.

This has solved my problem and connection from php5.6 to mysql 8.x was working great.

hope this helps.

You can use lodash sortBy (https://lodash.com/docs/4.17.4#sortBy).

Your code could be like:

const myArray = [  
   {  
      "id":25,
      "name":"Anakin Skywalker",
      "createdAt":"2017-04-12T12:48:55.000Z",
      "updatedAt":"2017-04-12T12:48:55.000Z"
   },
   {  
      "id":1,
      "name":"Luke Skywalker",
      "createdAt":"2017-04-12T11:25:03.000Z",
      "updatedAt":"2017-04-12T11:25:03.000Z"
   }
]

const myOrderedArray = _.sortBy(myArray, o => o.name)

Laravel - htmlspecialchars() expects parameter 1 to be string, object given.

thank me latter.........................

when you send or get array from contrller or function but try to print as single value or single variable in laravel blade file so it throws an error

->use any think who convert array into string it work.

solution: 1)run the foreach loop and get single single value and print. 2)The implode() function returns a string from the elements of an array. {{ implode($your_variable,',') }}

implode is best way to do it and its 100% work.

First thing you need to do here is correct the hibernate dialect version like @JavaLearner has explained. Then you have make sure that all the versions of hibernate dependencies you are using are upto date. Typically you would need: database driver like mysql-connector-java, hibernate dependency: hibernate-core and hibernate entity manager: hibernate-entitymanager. Lastly don't forget to check that the database tables you are using are not the reserved words like order, group, limit, etc. It might save you a lot of headache.

I also got this error .I was using Text inside body after changing to XML(text/xml) , got result as expected.

• If your request is XML Request use XML(text/xml).

• If your request is JSON Request use JSON(application/json)

In my case I had to clear browser history/cookies to get rid of this error.

This worked for me

/* Portrait */
@media only screen 
  and (min-device-width: 834px) 
  and (max-device-width: 834px) 
  and (orientation: portrait) 
  and (-webkit-min-device-pixel-ratio: 2) {

}

/* Landscape */
@media only screen 
  and (min-width: 1112px) 
  and (max-width: 1112px) 
  and (orientation: landscape) 
  and (-webkit-min-device-pixel-ratio: 2)
 {

}

I just wondered, why col-xs-6 did not work for me but then I found the answer in the Bootstrap 4 documentation. The class prefix for extra small devices is now col- while in the previous versions it was col-xs.

https://getbootstrap.com/docs/4.1/layout/grid/#grid-options

Bootstrap 4 dropped all col-xs-* classes, so use col-* instead. For example col-xs-6 replaced by col-6.

For some reason the responsive table in particular doesn't behave as it should. You can patch it by getting rid of display:block;

.table-responsive {
    display: table;
}

I may file a bug report.

Edit:

It is an existing bug.

It's the @Neps' answer but with details.

Note: @Saurabh's answer is more suitable if you don't want to modify your component or don't have access to it.

Why can't @click just work?

Components are complicated. One component can be a small fancy button wrapper, and another one can be an entire table with bunch of logic inside. Vue doesn't know what exactly you expect when bind v-model or use v-on so all of that should be processed by component's creator.

How to handle click event

According to Vue docs, $emit passes events to parent. Example from docs:

Main file

<blog-post
  @enlarge-text="onEnlargeText"
/>

Component

<button @click="$emit('enlarge-text')">
  Enlarge text
</button>

(@ is the v-on shorthand)

Component handles native click event and emits parent's @enlarge-text="..."

enlarge-text can be replaced with click to make it look like we're handling a native click event:

<blog-post
  @click="onEnlargeText"
></blog-post>

<button @click="$emit('click')">
  Enlarge text
</button>

But that's not all. $emit allows to pass a specific value with an event. In the case of native click, the value is MouseEvent (JS event that has nothing to do with Vue).

Vue stores that event in a $event variable. So, it'd the best to emit $event with an event to create the impression of native event usage:

<button v-on:click="$emit('click', $event)">
  Enlarge text
</button>

$about = DB::where('page', 'about-me')->first(); 

in stead of get().

It works on my project. Thanks.

You can just add style="min-height:100vh" to your page content conteiner and place footer in another conteiner

I solved this error using the bellow i get it from here

ionic cordova run browser will load those native plugins that support browser platform.

You can use default javascript cookies set method. this working perfect.

createCookieInHour: (cookieName, cookieValue, hourToExpire) => {
    let date = new Date();
    date.setTime(date.getTime()+(hourToExpire*60*60*1000));
    document.cookie = cookieName + " = " + cookieValue + "; expires = " +date.toGMTString();
},

call java scripts funtion in react method as below,

createCookieInHour('cookieName', 'cookieValue', 5);

and you can use below way to view cookies.

let cookie = document.cookie.split(';');
console.log('cookie : ', cookie);

please refer below document for more information - URL

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

Keep the json file in Assets (parallel to app dir) directory

Note that if you would have generated with ng new YourAppname- this assets directory exists same line with 'app' directory, and services should be child directory of app directory. May look like as below:

::app/services/myservice.ts

getOrderSummary(): Observable {
    // get users from api
    return this.http.get('assets/ordersummary.json')//, options)
        .map((response: Response) => {
            console.log("mock data" + response.json());
            return response.json();
        }
    )
    .catch(this.handleError);
} 

In case you are using node.js (with express)

If you want to serve static files in node.js, you need to use a function. Add the following code to your js file:

app.use(express.static("public"));

Where app is:

const express = require("express");
const app = express();

Then create a folder called public in you project folder. (You could call it something else, this is just good practice but remember to change it from the function as well.)

Then in this file create another folder named css (and/or images file under css if you want to serve static images as well.) then add your css files to this folder.

After you add them change the stylesheet accordingly. For example if it was:

href="cssFileName.css"

and

src="imgName.png"

Make them:

href="css/cssFileName.css"
src="css/images/imgName.png"

That should work

If you make an AJAX request with fetch, the response isn't shown unless it's read with .text(), .json(), etc.

If you just do:

 r = fetch("/some-path");

the response won't be shown in dev tools.
It shows up after you run:

r.then(r => r.text())

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

You can disable need to run Internet Explorer's first launch configuration by running this PowerShell script, it will adjust corresponding registry property:

Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Internet Explorer\Main" -Name "DisableFirstRunCustomize" -Value 2

After this, WebClient will work without problems

For the SpringBoot2 just add

httpResponse.setHeader("Access-Control-Expose-Headers", "custom-header1, custom-header2");

to your CORS filter implementation code to have whitelisted custom-header1 and custom-header2 etc

If you have a specific integer timestamp to insert/update, you can use PHP date() function with your timestamp as second arg :

date("Y-m-d H:i:s", $myTimestamp)

You need change url from https://android.googleapis.com/gcm/send to https://fcm.googleapis.com/fcm/send and change your app library too. this tutorial can help you https://firebase.google.com/docs/cloud-messaging/server#implementing-http-connection-server-protocol

Google recently changed the terms of use of its Google Maps APIs; if you were already using them on a website (different from localhost) prior to June 22nd, 2016, nothing will change for you; otherwise, you will get the aforementioned issue and need an API key in order to fix your error. The free API key is valid up to 25,000 map loads per day.

In this article you will find everything you may need to know regarding the topic, including a tutorial to fix your error:

Google Maps API error: MissingKeyMapError [SOLVED]

Also, remember to replace YOUR_API_KEY with your actual API key!

When you click the Button

if(isset($_POST['save'])){
        $sql = "INSERT INTO `members`(`id`, `membership_id`, `email`, `first_name`)
        VALUES ('".$_POST["id"]."','".$_POST["membership_id"]."','".$_POST["email"]."','".$_POST["firstname"]."')";
    **if ($conn->query($sql) === TRUE) {
        echo "New record created successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }**
}

This will execute the Query in the variable $sql

    if ($conn->query($sql) === TRUE) {
        echo "New record created successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }

I was having major problems with Axios, Spring Boot and Spring Security with authentication.

Please note the version of Spring Boot and the Spring Security you are using matters.

Spring Boot: 1.5.10 Spring: 4.3.14 Spring Security 4.2.4

To resolve this issue using Annotation Based Java Configuration I created the following class:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

        auth.inMemoryAuthentication()
                .withUser("youruser").password("yourpassword")
                .authorities("ROLE_USER");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http.cors().and().
                authorizeRequests()
                .requestMatchers(CorsUtils:: isPreFlightRequest).permitAll()
                .anyRequest()
                .authenticated()
                .and()
                .httpBasic()
                .realmName("Biometrix");

        http.csrf().disable();

    }

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowCredentials(true);
        configuration.setAllowedHeaders(Arrays.asList("Authorization"));
        configuration.setAllowedOrigins(Arrays.asList("*"));
        configuration.setAllowedMethods(Arrays.asList("*"));
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
}

One of the major gotchas with Axios is that when your API requires authentication it sends an Authorization header with the OPTIONS request. If you do not include Authorization in the allowed headers configuration setting our OPTIONS request (aka PreFlight request) will fail and Axios will report an error.

As you can see with a couple of simple and properly placed settings CORS configuration with SpringBoot is pretty easy.

It's been solved.

The losses only save to the History over the epochs. I was running iterations instead of using the Keras built in epochs option.

so instead of doing 4 iterations I now have

model.fit(......, nb_epoch = 4)

Now it returns the loss for each epoch run:

print(hist.history)
{'loss': [1.4358016599558268, 1.399221191623641, 1.381293383180471, h1.3758836857303727]}

Example for Slack.... (use your own web address you generate there)...

curl -X POST -H "Content-type:application/json" --data "{\"text\":\"A New Program Has Just Been Posted!!!\"}" https://hooks.slack.com/services/T7M0PFD42/BAA6NK48Y/123123123123123

I needed to add the script below to index.html inside the HEAD tag.

<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>

But in your case, since you don't have index.html, just add it to your HEAD tag instead.

So it's like:

<!doctype html>
<html>
<head>
   <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
...
</body>
</html>

You just need to add three file and two css links. You can either cdn's as well. Links for the js files and css files are as such :-

1. jQuery.dataTables.min.js
2. dataTables.bootstrap.min.js
3. dataTables.bootstrap.min.css
4. bootstrap-datepicker.css
5. bootstrap-datepicker.js

They are valid if you are using bootstrap in your project.

I hope this will help you. Regards, Vivek Singla

Take a look at the FormData object: https://developer.mozilla.org/en/docs/Web/API/FormData

this.uploadFileToUrl = function(file, uploadUrl){
        var fd = new FormData();
        fd.append('file', file);
        $http.post(uploadUrl, fd, {
            transformRequest: angular.identity,
            headers: {'Content-Type': undefined}
        })
        .success(function(){
        })
        .error(function(){
        });
    }

This is what I did to solve my problem. I tested in local MySQL 5.7 ubuntu 18.04.

set global sql_mode="NO_ENGINE_SUBSTITUTION";

Before running this query globally I added a cnf file in /etc/mysql/conf.d directory. The cnf file name is mysql.cnf and codes

[mysqld]
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ALLOW_INVALID_DATES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

Then I restart mysql

sudo service mysql restart

Hope this can help someone.

Even simpler:

body: new URLSearchParams({
      'userName': '[email protected]',
      'password': 'Password!',
      'grant_type': 'password'
    }),

I'm using Ubuntu 16.04 and PHP 5.6.20

After too many problems, the below steps solved this for me:

1. find php.ini path via phpinfo()

2. uncomment

   extension=php_pdo_mysql.dll
   

3. add this line

   extension=pdo_mysql.so
   

4. then run

   sudo apt-get install php-mysql
   

In my case it is Asp.Net Core 3.1 API. I changed the HTTP GET method from public ActionResult GetValidationRulesForField( GetValidationRulesForFieldDto getValidationRulesForFieldDto) to public ActionResult GetValidationRulesForField([FromQuery] GetValidationRulesForFieldDto getValidationRulesForFieldDto) and its working.

Access the field with array notation to avoid strict type checking on single field:

data['propertyName']; //will work even if data has not declared propertyName

Alternative way is (un)cast the variable for single access:

(<any>data).propertyName;//access propertyName like if data has no type

The first is shorter, the second is more explicit about type (un)casting

You can also totally disable type checking on all variable fields:

let untypedVariable:any= <any>{}; //disable type checking while declaring the variable
untypedVariable.propertyName = anyValue; //any field in untypedVariable is assignable and readable without type checking

Note: This would be more dangerous than avoid type checking just for a single field access, since all consecutive accesses on all fields are untyped

var theString = "TEST";
char[] myChar = theString.ToCharArray();

I tested this in the C# interactive window of Visual Studio 2019 and got:

char[4] { 'T', 'E', 'S', 'T' }

@PostMapping(path = "/my/endpoint", consumes = { MediaType.APPLICATION_FORM_URLENCODED_VALUE })
public ResponseEntity<Void> handleBrowserSubmissions(MyDTO dto) throws Exception {
    ...
}

That way works for me

Using return; will work just fine. It will not prevent the full loop from completing. It will only stop executing the current iteration of the forEach loop.

Try the following little program:

public static void main(String[] args) {
    ArrayList<String> stringList = new ArrayList<>();
    stringList.add("a");
    stringList.add("b");
    stringList.add("c");

    stringList.stream().forEach(str -> {
        if (str.equals("b")) return; // only skips this iteration.

        System.out.println(str);
    });
}

Output:

a
c

Notice how the return; is executed for the b iteration, but c prints on the following iteration just fine.

Why does this work?

The reason the behavior seems unintuitive at first is because we are used to the return statement interrupting the execution of the whole method. So in this case, we expect the main method execution as a whole to be halted.

However, what needs to be understood is that a lambda expression, such as:

str -> {
    if (str.equals("b")) return;

    System.out.println(str);
}

... really needs to be considered as its own distinct "method", completely separate from the main method, despite it being conveniently located within it. So really, the return statement only halts the execution of the lambda expression.

The second thing that needs to be understood is that:

stringList.stream().forEach()

... is really just a normal loop under the covers that executes the lambda expression for every iteration.

With these 2 points in mind, the above code can be rewritten in the following equivalent way (for educational purposes only):

public static void main(String[] args) {
    ArrayList<String> stringList = new ArrayList<>();
    stringList.add("a");
    stringList.add("b");
    stringList.add("c");

    for(String s : stringList) {
        lambdaExpressionEquivalent(s);
    }
}

private static void lambdaExpressionEquivalent(String str) {
    if (str.equals("b")) {
        return;
    }

    System.out.println(str);
}

With this "less magic" code equivalent, the scope of the return statement becomes more apparent.

You can use MarkerWithLabel with SVG icons.

Update: The Google Maps Javascript API v3 now natively supports multiple characters in the MarkerLabel

index.html should be inside templates, as I know. So, your second attempt looks correct.

But, as the error message says, index.html looks like having some errors. E.g. the in the third line, the meta tag should be actually head tag, I think.

I experienced this error with my WordPress site but I saw that there were two indexes showing in my developer tools sources.

Chrome Developer Tool Error So I had the thought that if there are two indexes starting at the first line of code then there's a replication and they're conflicting with each other. So I thought that then perhaps it's my HTML minification from my caching plugin tool.

So I turned off the HTML minify setting and deleted my cache. And poof! It worked!

I wrote this method to handle UTF8 arrays and JSON problems. It works fine with array (simple and multidimensional).

/**
 * Encode array from latin1 to utf8 recursively
 * @param $dat
 * @return array|string
 */
   public static function convert_from_latin1_to_utf8_recursively($dat)
   {
      if (is_string($dat)) {
         return utf8_encode($dat);
      } elseif (is_array($dat)) {
         $ret = [];
         foreach ($dat as $i => $d) $ret[ $i ] = self::convert_from_latin1_to_utf8_recursively($d);

         return $ret;
      } elseif (is_object($dat)) {
         foreach ($dat as $i => $d) $dat->$i = self::convert_from_latin1_to_utf8_recursively($d);

         return $dat;
      } else {
         return $dat;
      }
   }
// Sample use
// Just pass your array or string and the UTF8 encode will be fixed
$data = convert_from_latin1_to_utf8_recursively($data);

I've just managed to setup new TabLayout, so here are the quick steps to do this (????)?*:???

1. Add dependencies inside your build.gradle file:

   dependencies {
       compile 'com.android.support:design:23.1.1'
   }
   

2. Add TabLayout inside your layout

   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:orientation="vertical">
   
       <android.support.v7.widget.Toolbar
           android:id="@+id/toolbar"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:background="?attr/colorPrimary"/>
   
       <android.support.design.widget.TabLayout
           android:id="@+id/tab_layout"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"/>
   
       <android.support.v4.view.ViewPager
           android:id="@+id/pager"
           android:layout_width="match_parent"
           android:layout_height="match_parent"/>
   
   </LinearLayout>
   

3. Setup your Activity like this:

   import android.os.Bundle;
   import android.support.design.widget.TabLayout;
   import android.support.v4.app.Fragment;
   import android.support.v4.app.FragmentManager;
   import android.support.v4.app.FragmentPagerAdapter;
   import android.support.v4.view.ViewPager;
   import android.support.v7.app.AppCompatActivity;
   import android.support.v7.widget.Toolbar;
   
   public class TabLayoutActivity extends AppCompatActivity {
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_pull_to_refresh);
   
           Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
           TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
           ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
   
           if (toolbar != null) {
               setSupportActionBar(toolbar);
           }
   
           viewPager.setAdapter(new SectionPagerAdapter(getSupportFragmentManager()));
           tabLayout.setupWithViewPager(viewPager);
       }
   
       public class SectionPagerAdapter extends FragmentPagerAdapter {
   
           public SectionPagerAdapter(FragmentManager fm) {
               super(fm);
           }
   
           @Override
           public Fragment getItem(int position) {
               switch (position) {
                   case 0:
                       return new FirstTabFragment();
                   case 1:
                   default:
                       return new SecondTabFragment();
               }
           }
   
           @Override
           public int getCount() {
               return 2;
           }
   
           @Override
           public CharSequence getPageTitle(int position) {
               switch (position) {
                   case 0:
                       return "First Tab";
                   case 1:
                   default:
                       return "Second Tab";
               }
           }
       }
   
   }
   

i had the same problem and it seems like i didn't initiate the button used with click listener, in other words id didn't te

First line of the error message describes the error type: "PDOException". The next line displays PDO::errorInfo, i.e:

1. SQLSTATE error code (a five characters alphanumeric identifier defined in the ANSI SQL standard).
2. Driver-specific error code.
3. Driver-specific error message.

• "HY000" is a general server error (see Server Error Codes and Messages in MySQL docs).
• "2002" is MySQL Client Error Code meaning "Can't connect to local MySQL server through socket" (see (Client Error Codes and Messages in MySQL docs).
• The driver specific error code and message ("php_network_getaddresses: getaddrinfo failed: Name or service not known") tell you that PDO is not able to resolve the host name.

The stack trace you attached, line 3, reveals that you did not specify the database connection parameters in the configuration file. The error show up when you test on local, right? You need to update /.env with the actual database connection parameters.

• To restart mysql use this command

sudo service mysql restart

Or

sudo restart mysql

Reference

MySQL added this utf8mb4 code after 5.5.3, Mb4 is the most bytes 4 meaning, specifically designed to be compatible with four-byte Unicode. Fortunately, UTF8MB4 is a superset of UTF8, except that there is no need to convert the encoding to UTF8MB4. Of course, in order to save space, the general use of UTF8 is enough.

The original UTF-8 format uses one to six bytes and can encode 31 characters maximum. The latest UTF-8 specification uses only one to four bytes and can encode up to 21 bits, just to represent all 17 Unicode planes. UTF8 is a character set in Mysql that supports only a maximum of three bytes of UTF-8 characters, which is the basic multi-text plane in Unicode.

To save 4-byte-long UTF-8 characters in Mysql, you need to use the UTF8MB4 character set, but only 5.5. After 3 versions are supported (View version: Select version ();). I think that in order to get better compatibility, you should always use UTF8MB4 instead of UTF8. For char type data, UTF8MB4 consumes more space and, according to Mysql's official recommendation, uses VARCHAR instead of char.

In MariaDB utf8mb4 as the default CHARSET when it not set explicitly in the server config, hence COLLATE utf8mb4_unicode_ci is used.

Refer MariaDB CHARSET & COLLATE Click

CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

You guys copied the wrong code.

Go into the "/build" folder and grab the jquery.datetimepicker.full.js or jquery.datetimepicker.full.min.js if you want the minified version. It should fix it! :)

As previous answers have solved for, but should be stated very explicitly: the php code needs to live in the php-fpm container, while the static files need to live in the nginx container. For simplicity, most people have just attached all the code to both, as I have also done below. If the future, I will likely separate out these different parts of the code in my own projects as to minimize which containers have access to which parts.

Updated my example files below with this latest revelation (thank you @alkaline )

This seems to be the minimum setup for docker 2.0 forward (because things got a lot easier in docker 2.0)

docker-compose.yml:

version: '2'
services:
  php:
    container_name: test-php
    image: php:fpm
    volumes:
      - ./code:/var/www/html/site
  nginx:
    container_name: test-nginx
    image: nginx:latest
    volumes:
      - ./code:/var/www/html/site
      - ./site.conf:/etc/nginx/conf.d/site.conf:ro
    ports:
      - 80:80

(UPDATED the docker-compose.yml above: For sites that have css, javascript, static files, etc, you will need those files accessible to the nginx container. While still having all the php code accessible to the fpm container. Again, because my base code is a messy mix of css, js, and php, this example just attaches all the code to both containers)

In the same folder:

site.conf:

server
{
    listen   80;
    server_name site.local.[YOUR URL].com;

    root /var/www/html/site;
    index index.php;

    location /
    {
        try_files $uri =404;
    }

    location ~ \.php$ {
        fastcgi_pass   test-php:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

In folder code:

./code/index.php:

<?php
phpinfo();

and don't forget to update your hosts file:

127.0.0.1 site.local.[YOUR URL].com

and run your docker-compose up

$docker-compose up -d

and try the URL from your favorite browser

site.local.[YOUR URL].com/index.php

I had the same problem with my application. My project uses DevOps and The problem was because of the unhealthy computes. Replacing them fixed the issue for me

<div class="prev">Prev</div>

<div class="next">Next</div>

$('.your_class').slick({
        infinite: true,
        speed: 300,
        slidesToShow: 5,
        slidesToScroll: 5,
        arrows: true,
        prevArrow: $('.prev'),
        nextArrow: $('.next')
});

That meta tag basically specifies which character set a website is written with.

Here is a definition of UTF-8:

UTF-8 (U from Universal Character Set + Transformation Format—8-bit) is a character encoding capable of encoding all possible characters (called code points) in Unicode. The encoding is variable-length and uses 8-bit code units.

in my case (laravel 5+) i had to wrap my password in single quotation marks and clear config cache:

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=user_name
DB_PASSWORD='password'

and then run:

php artisan config:clear

1. Edit the file .env in your laravel root directory. make looks as in below :

    DB_HOST=localhost
    DB_DATABASE=laravel
    DB_USERNAME=root
    DB_PASSWORD=your-root-pas
   

2. Also create one database in phpmyadmin named, "laravel".

3. Run below commands :

    php artisan cache:clear
    php artisan config:cache
    php artisan config:clear   
    php artisan migrate
   

It worked for me, XAMPP with Apache and MySQL.

@Nishit, JSONObject does not natively understand how to parse through a StringBuilder; instead you appear to be using the JSONObject(java.lang.Object bean) constructor to create the JSONObject, however passing it a StringBuilder.

See this link for more information on that particular constructor.

http://www.json.org/javadoc/org/json/JSONObject.html#JSONObject%28java.lang.Object%29

When a constructor calls for a java.lang.Object class, more than likely it's really telling you that you're expected to create your own class (since all Classes ultimately extend java.lang.Object) and that it will interface with that class in a specific way, albeit normally it will call for an interface instead (hence the name) OR it can accept any class and interface with it "abstractly" such as calling .toString() on it. Bottom line, you typically can't just pass it any class and expect it to work.

At any rate, this particular constructor is explained as such:

Construct a JSONObject from an Object using bean getters. It reflects on all of the public methods of the object. For each of the methods with no parameters and a name starting with "get" or "is" followed by an uppercase letter, the method is invoked, and a key and the value returned from the getter method are put into the new JSONObject. The key is formed by removing the "get" or "is" prefix. If the second remaining character is not upper case, then the first character is converted to lower case. For example, if an object has a method named "getName", and if the result of calling object.getName() is "Larry Fine", then the JSONObject will contain "name": "Larry Fine".

So, what this means is that it's expecting you to create your own class that implements get or is methods (i.e.

public String getName() {...}

or

public boolean isValid() {...}

So, to solve your problem, if you really want that higher level of control and want to do some manipulation (e.g. modify some values, etc.) but still use StringBuilder to dynamically generate the code, you can create a class that extends the StringBuilder class so that you can use the append feature, but implement get/is methods to allow JSONObject to pull the data out of it, however this is likely not what you want/need and depending on the JSON, you might spend a lot of time and energy creating the private fields and get/is methods (or use an IDE to do it for you) or it might be all for naught if you don't necessarily know the breakdown of the JSON string.

So, you can very simply call toString() on the StringBuilder which will provide a String representation of the StringBuilder instance and passing that to the JSONObject constructor, such as below:

...
StringBuilder jsonString = new StringBuilder();
while((readAPIResponse = br.readLine()) != null){
    jsonString.append(readAPIResponse);
}
JSONObject jsonObj = new JSONObject(jsonString.toString());
...

The new testing improvements that debuted in Spring Boot 1.4.M2 can help reduce the amount of code you need to write situation such as these.

The test would look like so:

Your form is also missing '{{csrf_field()}}'

Updated based on Muhammad's answer...

$http.get('/someUrl').
  success(function(data, status, headers, config) {
    // this callback will be called asynchronously
    // when the response is available
    console.log(headers()['Content-Range']);
  })
  .error(function(data, status, headers, config) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

you can implement your adapter's onClickListener:

  public class AdapterClass extends RecyclerView.Adapter<AdapterClass.MyViewHolder>implements View.OnClickListener

and use interface with method in it

public interface mClickListener {
    public void mClick(View v, int position);
}

and in your onClick method call the method in the interface and pass it the view and position

in your main activity implement that interface

public class MainActivity extends ActionBarActivity implements AdapterClass.mClickListener

and override that method

@Override
public void onCommentsClick(View v, int position) {
    final Intent intent = new Intent(this, OtherActivity.class);
}

as its better to manage your activity transition by the activity not other classes

the solution to this problem differs because each time you deploy the application will give you the same sentence or the problem is different, so you should see the tomcat server log for the exact problem.

The Base64.Encoder.encodeToString method automatically uses the ISO-8859-1 character set.

For an encryption utility I am writing, I took the input string of cipher text and Base64 encoded it for transmission, then reversed the process. Relevant parts shown below. NOTE: My file.encoding property is set to ISO-8859-1 upon invocation of the JVM so that may also have a bearing.

static String getBase64EncodedCipherText(String cipherText) {
    byte[] cText = cipherText.getBytes();
    // return an ISO-8859-1 encoded String
    return Base64.getEncoder().encodeToString(cText);
}

static String getBase64DecodedCipherText(String encodedCipherText) throws IOException {
    return new String((Base64.getDecoder().decode(encodedCipherText)));
}

public static void main(String[] args) {
    try {
        String cText = getRawCipherText(null, "Hello World of Encryption...");

        System.out.println("Text to encrypt/encode: Hello World of Encryption...");
        // This output is a simple sanity check to display that the text
        // has indeed been converted to a cipher text which 
        // is unreadable by all but the most intelligent of programmers.
        // It is absolutely inhuman of me to do such a thing, but I am a
        // rebel and cannot be trusted in any way.  Please look away.
        System.out.println("RAW CIPHER TEXT: " + cText);
        cText = getBase64EncodedCipherText(cText);
        System.out.println("BASE64 ENCODED: " + cText);
        // There he goes again!!
        System.out.println("BASE64 DECODED:  " + getBase64DecodedCipherText(cText));
        System.out.println("DECODED CIPHER TEXT: " + decodeRawCipherText(null, getBase64DecodedCipherText(cText)));
    } catch (Exception e) {
        e.printStackTrace();
    }

}

The output looks like:

Text to encrypt/encode: Hello World of Encryption...
RAW CIPHER TEXT: q$;?C?l??<8??U???X[7l
BASE64 ENCODED: HnEPJDuhQ+qDbInUCzw4gx0VDqtVwef+WFs3bA==
BASE64 DECODED:  q$;?C?l??<8??U???X[7l``
DECODED CIPHER TEXT: Hello World of Encryption...

I don't think you want the data from your Request, I think you want the data from your Response. The two are different. Also you should build your response correctly in your controller.

Looking at the class in edit #2, I would make it look like this:

class XmlController extends Controller
{
    public function index()
    {
        $content = Request::all();
        return Response::json($content);
    }
}

Once you've gotten that far you should check the content of your response in your test case (use print_r if necessary), you should see the data inside.

I had the same issue with a site which previously was running fine. I resolved the issue by deleting the temporary files from C:\WINDOWS\Microsoft.NET\Framework\v#.#.#####\Temporary ASP.NET Files\@projectName\###CC##C\###C#CC

  var data = JSON.stringify
            ({
            'StrContactDetails': Details,
            'IsPrimary': true
            })

Submit is null because it is not part of activity_main.xml

When you call findViewById inside an Activity, it is going to look for a View inside your Activity's layout.

try this instead :

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

Another thing : you use

android:layout_below="@+id/LoginTitle"

but what you want is probably

android:layout_below="@id/LoginTitle"

See this question about the difference between @id and @+id.

The problem is the tv.setText(text). The variable tv is probably null and you call the setText method on that null, which you can't. My guess that the problem is on the findViewById method, but it's not here, so I can't tell more, without the code.

If you are using bootstrap then the below solution will work.

<div>
    <button type="submit" class="btn btn-primary" >Invoke User Endpoint</button>
    <button type="submit" class="btn btn-primary ml-3">Invoke Hello Endpoint</button>
</div>

In my case, there was no string on which i was calling appendChild, the object i was passing on appendChild argument was wrong, it was an array and i had pass an element object, so i used divel.appendChild(childel[0]) instead of divel.appendChild(childel) and it worked. Hope it help someone.

In my case, the root cause of this exception comes from using an old version mysql-connector and I had this error :

unable to load authentication plugin 'caching_sha2_password'. mysql

Adding this line to the mysql server configuration file (my.cnf or my.ini) fix this issue :

default_authentication_plugin=mysql_native_password

Well, the problem is that Files.newBufferedReader(Path path) is implemented like this :

public static BufferedReader newBufferedReader(Path path) throws IOException {
    return newBufferedReader(path, StandardCharsets.UTF_8);
}

so basically there is no point in specifying UTF-8 unless you want to be descriptive in your code. If you want to try a "broader" charset you could try with StandardCharsets.UTF_16, but you can't be 100% sure to get every possible character anyway.

To use AUTO_INCREMENT you need to deifne column as INT or floating-point types, not CHAR.

AUTO_INCREMENT use only unsigned value, so it's good to use UNSIGNED as well;

CREATE TABLE discussion_topics (

     topic_id INT NOT NULL unsigned AUTO_INCREMENT,
     project_id char(36) NOT NULL,
     topic_subject VARCHAR(255) NOT NULL,
     topic_content TEXT default NULL,
     date_created DATETIME NOT NULL,
     date_last_post DATETIME NOT NULL,
     created_by_user_id char(36) NOT NULL,
     last_post_user_id char(36) NOT NULL,
     posts_count char(36) default NULL,
     PRIMARY KEY (topic_id) 
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;

Yor $.post has no data. You need to pass the form data. You can use serialize() to post the form data. Try this

$("#post-btn").click(function(){
    $.post("process.php", $('#reg-form').serialize() ,function(data){
        alert(data);
    });
});

The same error is produced in MariaDB (10.1.36-MariaDB) by using the combination of parenthesis and the COLLATE statement. My SQL was different, the error was the same, I had:

SELECT *
FROM table1
WHERE (field = 'STRING') COLLATE utf8_bin;

Omitting the parenthesis was solving it for me.

SELECT *
FROM table1
WHERE field = 'STRING' COLLATE utf8_bin;

In Controller, your method should be;

@RequestMapping(value = "/upload", method = RequestMethod.POST)
    public ResponseEntity<SaveResponse> uploadAttachment(@RequestParam("file") MultipartFile file, HttpServletRequest request) {
....

Further, you need to update application.yml (or application.properties) to support maximum file size and request size.

spring:
    http:
        multipart:
            max-file-size: 5MB
            max-request-size: 20MB

The question is a bit old but I just solved a very similar problem. We have several intranet sites here including the one I'm responsible for, and the others require compatibility mode or they break. For that reason, site rules default IE to compatibility mode on intranet sites. I am upgrading my own stuff and no longer need it; in fact, some of the features I'm trying to use don't look right in compat mode. I'm using the meta IE-Edge tag like you are.

IE assumes websites without the fully-qualified address are intranet, and acts accordingly. With that in mind I just altered the bindings in IIS to only listen to the fully-qualified address, then set up a dummy website that listened for the unqualified address. The second one redirects all traffic to the fully-qualified address, making IE believe it's an external site. The site renders correctly with or without the Compatibility Mode on Intranet Sites box checked.

My answer is WRT python 2.6.2.

import commands

status, output = commands.getstatusoutput("curl -H \"Content-Type:application/json\" -k -u (few other parameters required) -X GET https://example.org -s")

print output

I apologize for not providing the required parameters 'coz it's confidential.

Be sure to configure the 'default' key in app/config/database.php

For postgres, this would be 'default' => 'postgres',

If you are receiving a [PDOException] could not find driver error, check to see if you have the correct PHP extensions installed. You need pdo_pgsql.so and pgsql.so installed and enabled. Instructions on how to do this vary between operating systems.

For Windows, the pgsql extensions should come pre-downloaded with the official PHP distribution. Just edit your php.ini and uncomment the lines extension=pdo_pgsql.so and extension=pgsql.so

Also, in php.ini, make sure extension_dir is set to the proper directory. It should be a folder called extensions or ext or similar inside your PHP install directory.

Finally, copy libpq.dll from C:\wamp\bin\php\php5.*\ into C:\wamp\bin\apache*\bin and restart all services through the WampServer interface.

If you still get the exception, you may need to add the postgres \bin directory to your PATH:

1. System Properties -> Advanced tab -> Environment Variables
2. In 'System variables' group on lower half of window, scroll through and find the PATH entry.
3. Select it and click Edit
4. At the end of the existing entry, put the full path to your postgres bin directory. The bin folder should be located in the root of your postgres installation directory.
5. Restart any open command prompts, or to be certain, restart your computer.

This should hopefully resolve any problems. For more information see:

• http://php.net/manual/en/install.pecl.windows.php
• http://webcheatsheet.com/php/install_and_configure.php#extsetup

We see this a lot with OAuth2 integrations. We provide API services to our Customers, and they'll naively try to put their private key into an AJAX call. This is really poor security. And well-coded API Gateways, backends for frontend, and other such proxies, do not allow this. You should get this error.

I will quote @aspillers comment and change a single word: "Access-Control-Allow-Origin is a header sent in a server response which indicates IF the client is allowed to see the contents of a result".

ISSUE: The problem is that a developer is trying to include their private key inside a client-side (browser) JavaScript request. They will get an error, and this is because they are exposing their client secret.

SOLUTION: Have the JavaScript web application talk to a backend service that holds the client secret securely. That backend service can authenticate the web app to the OAuth2 provider, and get an access token. Then the web application can make the AJAX call.

DataTables has functionality for this since v 1.10

https://datatables.net/reference/option/createdRow

Example:

$('#tid_css').DataTable({
  // ...
  "createdRow": function(row, data, dataIndex) {
    if (data["column_index"] == "column_value") {
      $(row).css("background-color", "Orange");
      $(row).addClass("warning");
    }
  },
  // ...
});

I figured out the answer to above problem. Below query will return rows which have even a signle occurrence of characters besides alphabets, numbers, square brackets, curly brackets,s pace and dot. Please note that position of closing bracket ']' in matching pattern is important.

Right ']' has the special meaning of ending a character set definition. It wouldn't make any sense to end the set before you specified any members, so the way to indicate a literal right ']' inside square brackets is to put it immediately after the left '[' that starts the set definition

SELECT * FROM test WHERE REGEXP_LIKE(sampletext,  '[^]^A-Z^a-z^0-9^[^.^{^}^ ]' );

Assuming that your button is in a form, you are not preventing the default behaviour of the button click from happening i.e. Your AJAX call is made in addition to the form submission; what you're very likely seeing is one of

1. the form submission happens faster than the AJAX call returns
2. the form submission causes the browser to abort the AJAX request and continues with submitting the form.

So you should prevent the default behaviour of the button click

$('#btnSave').click(function (e) {

    // prevent the default event behaviour    
    e.preventDefault();

    $.ajax({
        url: "/Home/SaveDetailedInfo",
        type: "POST",
        data: JSON.stringify({ 'Options': someData}),
        dataType: "json",
        traditional: true,
        contentType: "application/json; charset=utf-8",
        success: function (data) {

            // perform your save call here

            if (data.status == "Success") {
                alert("Done");
            } else {
                alert("Error occurs on the Database level!");
            }
        },
        error: function () {
            alert("An error has occured!!!");
        }
    });
});

Building on what is mentioned in the comments, the simplest solution would be:

@RequestMapping(method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Collection<BudgetDTO> updateConsumerBudget(@RequestBody SomeDto someDto) throws GeneralException, ParseException {

    //whatever

}

class SomeDto {

   private List<WhateverBudgerPerDateDTO> budgetPerDate;


  //getters setters
}

The solution assumes that the HTTP request you are creating actually has

Content-Type:application/json instead of text/plain

For seekers of missing font-awesome icons, I have collected a few ideas:

• Assure you use a correct link to the CDN, such as:

  <link 
    href="http://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.3.0/css/font-awesome.css" 
    rel="stylesheet"  type='text/css'>
  

• If your page uses HTTPS, do you link to the font-awesome CSS using HTTPS (replace http:// with https:// in the link above).

• Double check that you don't have AdBlock Plus or uBlock enabled. They might be blocking some of the icons.

• Reset your browsers cache. (On Chrome do a looong click on the reload button and select Hard Cache Reset)

• Assure that the <span> or <i> element you use, uses the FontAwesome font family. For example, it must not just

  <i class="fa-pencil" title="Edit"></i>
  

  but

  <i class="fa fa-pencil" title="Edit"></i>
  

  It won't work if you have something as the following in your CSS:

  * {
    font-family: 'Josefin Sans', sans-serif !important;   
  }
  

• If you are using IE8, are you using a HTML5 Shim?

• If this doesn't work, there are further Troubleshooting Ideas on the Font Awesome Wiki.

Just an addendum:

OnFragmentInteractionListener handle communication between Activity and Fragment using an interface (OnFragmentInteractionListener) and is created by default by Android Studio, but if you dont need to communicate with your activity, you can just get ride of it.

The goal is that you can attach your fragment to multiple activities and still reuse the same communication approach (Every activity could have its own OnFragmentInteractionListener for each fragment).

But and if im sure my fragment will be attached to only one type of activity and i want to communicate with that activity?

Then, if you dont want to use OnFragmentInteractionListener because of its verbosity, you can access your activity methods using:

((MyActivityClass) getActivity()).someMethod()

You can implement search filter in listview by two ways. 1. using searchview 2. using edittext.

1. If yo want to use searchview then read here : searchview filter.

2. If you want to use edittext, read below.

I have taken reference from : listview search filter android

Code snippets to make filter with edittext.

First create model class MovieNames.java:

public class MovieNames {
    private String movieName;

    public MovieNames(String movieName) {
        this.movieName = movieName;
    }

    public String getMovieName() {
        return this.movieName;
    }

}

Create listview_item.xml file :

     <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dp">


    <TextView
        android:id="@+id/name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</RelativeLayout>

Make ListViewAdapter.java class :

    import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

import java.util.ArrayList;
import java.util.Locale;

public class ListViewAdapter extends BaseAdapter {

    // Declare Variables

    Context mContext;
    LayoutInflater inflater;
    private ArrayList<MovieNames> arraylist;

    public ListViewAdapter(Context context, ArrayList<MovieNames> arraylist) {
        mContext = context;
        inflater = LayoutInflater.from(mContext);
        this.arraylist = arraylist;

    }

    public class ViewHolder {
        TextView name;
    }

    @Override
    public int getCount() {
        return arraylist.size();
    }

    @Override
    public MovieNames getItem(int position) {
        return arraylist.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    public View getView(final int position, View view, ViewGroup parent) {
        final ViewHolder holder;
        if (view == null) {
            holder = new ViewHolder();
            view = inflater.inflate(R.layout.listview_item, null);
            // Locate the TextViews in listview_item.xml
            holder.name = (TextView) view.findViewById(R.id.name);
            view.setTag(holder);
        } else {
            holder = (ViewHolder) view.getTag();
        }
        // Set the results into TextViews
        holder.name.setText(arraylist.get(position).getMovieName());
        return view;
    }


} 

Prepare activity_main.xml file :

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.parsaniahardik.searchedit.MainActivity"
    android:orientation="vertical">


    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/editText"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:hint="enter query"
        android:singleLine="true">


        <requestFocus/>
    </EditText>

    <ListView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/listView"
        android:divider="#694fea"
        android:dividerHeight="1dp" />


</LinearLayout>

Finally make MainActivity.java class :

    import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.util.Log;
import android.view.View;
import android.widget.AdapterView;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.SearchView;
import android.widget.Toast;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

    private EditText etsearch;
    private ListView list;
    private ListViewAdapter adapter;
    private String[] moviewList;
    public static ArrayList<MovieNames> movieNamesArrayList;
    public static ArrayList<MovieNames> array_sort;
    int textlength = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Generate sample data

        moviewList = new String[]{"Xmen", "Titanic", "Captain America",
                "Iron man", "Rocky", "Transporter", "Lord of the rings", "The jungle book",
                "Tarzan","Cars","Shreck"};

        list = (ListView) findViewById(R.id.listView);

        movieNamesArrayList = new ArrayList<>();
        array_sort = new ArrayList<>();

        for (int i = 0; i < moviewList.length; i++) {
            MovieNames movieNames = new MovieNames(moviewList[i]);
            // Binds all strings into an array
            movieNamesArrayList.add(movieNames);
            array_sort.add(movieNames);
        }

        adapter = new ListViewAdapter(this,movieNamesArrayList);
        list.setAdapter(adapter);


        etsearch = (EditText) findViewById(R.id.editText);

        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(MainActivity.this, array_sort.get(position).getMovieName(), Toast.LENGTH_SHORT).show();
            }
        });

        etsearch.addTextChangedListener(new TextWatcher() {


            public void afterTextChanged(Editable s) {
            }

            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }

            public void onTextChanged(CharSequence s, int start, int before, int count) {
                textlength = etsearch.getText().length();
                array_sort.clear();
                for (int i = 0; i < movieNamesArrayList.size(); i++) {
                    if (textlength <= movieNamesArrayList.get(i).getMovieName().length()) {
                        Log.d("ertyyy",movieNamesArrayList.get(i).getMovieName().toLowerCase().trim());
                        if (movieNamesArrayList.get(i).getMovieName().toLowerCase().trim().contains(
                                etsearch.getText().toString().toLowerCase().trim())) {
                            array_sort.add(movieNamesArrayList.get(i));
                        }
                    }
                }
                    adapter = new ListViewAdapter(MainActivity.this, array_sort);
                    list.setAdapter(adapter);

            }
        });

    }
}

Since you return to the client just String and its content type == 'text/plain', there is no any chance for default converters to determine how to convert String response to the FFSampleResponseHttp object.

The simple way to fix it:

• remove expected-response-type from <int-http:outbound-gateway>
• add to the replyChannel1 <json-to-object-transformer>

Otherwise you should write your own HttpMessageConverter to convert the String to the appropriate object.

To make it work with MappingJackson2HttpMessageConverter (one of default converters) and your expected-response-type, you should send your reply with content type = 'application/json'.

If there is a need, just add <header-enricher> after your <service-activator> and before sending a reply to the <int-http:inbound-gateway>.

So, it's up to you which solution to select, but your current state doesn't work, because of inconsistency with default configuration.

UPDATE

OK. Since you changed your server to return FfSampleResponseHttp object as HTTP response, not String, just add contentType = 'application/json' header before sending the response for the HTTP and MappingJackson2HttpMessageConverter will do the stuff for you - your object will be converted to JSON and with correct contentType header.

From client side you should come back to the expected-response-type="com.mycompany.MyChannel.model.FFSampleResponseHttp" and MappingJackson2HttpMessageConverter should do the stuff for you again.

Of course you should remove <json-to-object-transformer> from you message flow after <int-http:outbound-gateway>.

It depends on when the self executing anonymous function is running. It is possible that it is running before window.document is defined.

In that case, try adding a listener

window.addEventListener('load', yourFunction, false);
// ..... or 
window.addEventListener('DOMContentLoaded', yourFunction, false);

yourFunction () {
  // some ocde

}

Update: (after the update of the question and inclusion of the code)

Read the following about the issues in referencing DOM elements from a JavaScript inserted and run in head element:
- “getElementsByTagName(…)[0]” is undefined?
- Traversing the DOM

FireFox is reporting that the response did not even specify the character encoding in the header, eg. Content-Type: text/html; charset=utf-8 and not just Content-Type: text/plain;.

What web server are you using? Are you sure you are not requesting a non-existing page (404) that responds poorly?

Add this to your section:

<script>
  function resizeIframe(obj) {
    obj.style.height = obj.contentWindow.document.body.scrollHeight + 'px';
  }
</script>

And change your iframe to this:

<iframe src="..." frameborder="0" scrolling="no" onload="resizeIframe(this)" />

It is posted Here

It does however use javascript, but it is simple and easy to use code that will fix your problem.

write

php artisan config:cache 

in your terminal and it will be fixed

You could implement a showfile function which takes in parameters of the data returned from the WEBApi, and a filename for the file you are trying to download. What I did was create a separate browser service identifies the user's browser and then handles the rendering of the file based on the browser. For instance if the target browser is chrome on an ipad, you have to use javascripts FileReader object.

FileService.showFile = function (data, fileName) {
    var blob = new Blob([data], { type: 'application/pdf' });

    if (BrowserService.isIE()) {
        window.navigator.msSaveOrOpenBlob(blob, fileName);
    }
    else if (BrowserService.isChromeIos()) {
        loadFileBlobFileReader(window, blob, fileName);
    }
    else if (BrowserService.isIOS() || BrowserService.isAndroid()) {
        var url = URL.createObjectURL(blob);
        window.location.href = url;
        window.document.title = fileName;
    } else {
        var url = URL.createObjectURL(blob);
        loadReportBrowser(url, window,fileName);
    }
}


function loadFileBrowser(url, window, fileName) {
    var iframe = window.document.createElement('iframe');
    iframe.src = url
    iframe.width = '100%';
    iframe.height = '100%';
    iframe.style.border = 'none';
    window.document.title = fileName;
    window.document.body.appendChild(iframe)
    window.document.body.style.margin = 0;
}

function loadFileBlobFileReader(window, blob,fileName) {
    var reader = new FileReader();
    reader.onload = function (e) {
        var bdata = btoa(reader.result);
        var datauri = 'data:application/pdf;base64,' + bdata;
        window.location.href = datauri;
        window.document.title = fileName;
    }
    reader.readAsBinaryString(blob);
}

Go to inspect element and check if .justify-content-center is listed as a class name under 'Styles' tab. If not, probably you are using bootstrap v3 in which justify-content-center is not defined.

If so, please update bootstrap, worked for me.

replace operates on a specific string, so you need to call it like this

removeSpecialChars = z.replace("!@#$%^&*()[]{};:,./<>?\|`~-=_+", " ")

but this is probably not what you need, since this will look for a single string containing all that characters in the same order. you can do it with a regexp, as Danny Michaud pointed out.

as a side note, you might want to look for BeautifulSoup, which is a library for parsing messy HTML formatted text like what you usually get from scaping websites.

app.factory('getSettings', ['$http','$q' /*here!!!*/,function($http, $q) {

you need to declare ALL your dependencies OR none and you forgot to declare $q .

edit:

controller.js : login, dont return ""

The answer to your original question

How to read a string one char at the time, and stop when you reach end of line?

is, in C++, very simply, namely: use getline. The link shows a simple example:

#include <iostream>
#include <string>
int main () {
  std::string name;
  std::cout << "Please, enter your full name: ";
  std::getline (std::cin,name);
  std::cout << "Hello, " << name << "!\n";
  return 0;
}

Do you really want to do this in C? I wouldn't! The thing is, in C, you have to allocate the memory in which to place the characters you read in? How many characters? You don't know ahead of time. If you allocate too few characters, you will have to allocate a new buffer every time to realize you reading more characters than you made room for. If you over-allocate, you are wasting space.

C is a language for low-level programming. If you are new to programming and writing simple applications for reading files line-by-line, just use C++. It does all that memory allocation for you.

Your later questions regarding "\0" and end-of-lines in general were answered by others and do apply to C as well as C++. But if you are using C, please remember that it's not just the end-of-line that matters, but memory allocation as well. And you will have to be careful not to overrun your buffer.

I think your issue may be in the url pattern. Changing

<servlet-mapping>
    <servlet-name>Register</servlet-name>
    <url-pattern>/Register</url-pattern>
</servlet-mapping>

and

<form action="/Register" method="post">

may fix your problem

Use this

<script>
$(document).ready(function(){
    $( '.expand' ).click(function() {
        $( '.img_display_content' ).show();
    });
});
</script>

Event assigning always after Document Object Model loaded

You will have to define Serializer Formatter within WebApiConfig.cs available in App_Start Folder like

Adding config.Formatters.Remove(config.Formatters.XmlFormatter); // which will provide you data in JSON Format

Adding config.Formatters.Remove(config.Formatters.JsonFormatter); // which will provide you data in XML Format

use this code it is working

// index.jsp or login.jsp

In C the char type has a numeric value so the > operator will work just fine for example

#include <stdio.h>
main() {

    char a='z';

    char b='h';

    if ( a > b ) {
        printf("%c greater than %c\n",a,b);
    }
}

BlobBuilder is obsolete, use Blob constructor instead:

URL.createObjectURL(new Blob([/*whatever content*/] , {type:'text/plain'}));

This returns a blob URL which you can then use in an anchor's href. You can also modify an anchor's download attribute to manipulate the file name:

<a href="/*assign url here*/" id="link" download="whatever.txt">download me</a>

Fiddled. If I recall correctly, there are arbitrary restrictions on trusted non-user initiated downloads; thus we'll stick with a link clicking which is seen as sufficiently user-initiated :)

Update: it's actually pretty trivial to save current document's html! Whenever our interactive link is clicked, we'll update its href with a relevant blob. After executing the click-bound event, that's the download URL that will be navigated to!

$('#link').on('click', function(e){
  this.href = URL.createObjectURL(
    new Blob([document.documentElement.outerHTML] , {type:'text/html'})
  );
});

Fiddled again.

If you are making jquery ajax request, dont forget to add

contentType:'application/json'

I had simillar issue with maven tests on x86 linux which i was using in terminal. I was logging in to linux by ssh. I started my java selenium tests by

mvn -DargLine="-Dbaseurl=http://http://127.0.0.1:8080/web/" install

Excepting my app, after running these tests I received error in logs:

unknown error: Chrome failed to start: exited abnormally

I was running these tests as root user. Before this error i received that ChromeDriver is nor present. I moved forward with this by installing ChromeDriver binary and adding it to PATH. But then i had to install google-chrome browser - ChromeDriver alone isn't enough to run tests. So the mistake is problem maybe with screen buffer in terminal window, but You can install Xvfb which is virtual screen buffer. What is important, that you should run your tests not as root, because you may receive another Chrome Browser error. So no as root i run:

export DISPLAY=:99
Xvfb :99 -ac -screen 0 1280x1024x24 &

What is important here, that in my case the number related to DISPLAY ought to be same as Xvfb :NN parameter. 99 in that case. I had another problem because i ran Xvfb with another DISPLAY value and I wanted it to stop. In order to restart Xvfb:

ps -aux | grep Xvfb
kill -9 PID
sudo rm /tmp/.X11-unix/X99

So find a process PID with grep. Kill Xvfb process. And then there is lock in /tmp/.X11-unix/XNN , so delete this lock and you can start server again. If You run not as root, set simillar displays, install google-chrome then with maven you can start selenium tests. My tests went fine with these rules and operations.

Had the same issue and just figured, website is running under MAMP's php, but when you call in command, it runs mac's(if no bash path modified). you will have issue when mac doesn't have those extensions.

run php -i to find out loaded extensions, and install those one you missed. or run '/Applications/MAMP/bin/php/php5.3.6/bin/php artisan {your command}' to use MAMP's

In here:

    if (ValidationUtils.isNullOrEmpty(lastName)) {
        registrationErrors.add(ValidationErrors.LAST_NAME);
    }
    if (!ValidationUtils.isEmailValid(email)) {
        registrationErrors.add(ValidationErrors.EMAIL);
    }

you check for null or empty value on lastname, but in isEmailValid you don't check for empty value. Something like this should do

    if (ValidationUtils.isNullOrEmpty(email) || !ValidationUtils.isEmailValid(email)) {
        registrationErrors.add(ValidationErrors.EMAIL);
    }

or better yet, fix your ValidationUtils.isEmailValid() to cope with null email values. It shouldn't crash, it should just return false.

Use like this on dropdown change
$("#assetgroupSelect").change(function(){
    $("#idValue").val($this.val());
})

you code is fine but never executed, cause of submit button [type="submit"] just replace it by type=button

<input value="Submit" type="button" onclick="submitform()">

inside your script; form is not declared.

let form = document.forms[0];
xhr.open(form.method, form.action, true);

It seems to be a browser bug.

10690: Reported a bug in Firefox for responsive images (those with max-width: 100%) in table cells. No other browsers are affected. See

https://bugzilla.mozilla.org/show_bug.cgi?id=975632.

.img-responsive in <fieldset> have the same behaviour.

In addition to all the answers, if you happen to receive in response text/html while you've expected something else (i.e. application/json), it may suggest that an error occurred on the server side (say 404) and the error page was returned instead of your data.

So it happened in my case. Hope it will save somebody's time.

You are sending a array of string

var usersRoles = [];
jQuery("#dualSelectRoles2 option").each(function () {
    usersRoles.push(jQuery(this).val());
});   

So change model type accordingly

 public ActionResult AddUser(List<string> model)
 {
 }

instead of receiving the json string a model binding is better. For example:

[HttpPost]       
public ActionResult AddUser(UserAddModel model)
{
    if (ModelState.IsValid) {
        return Json(new { Response = "Success" });
    }
    return Json(new { Response = "Error" });
}

<script>
function submitForm() {    
    $.ajax({
        type: 'POST',
        url: "@Url.Action("AddUser")",
        contentType: "application/json; charset=utf-8",
        dataType: 'json',
        data: $("form[name=UserAddForm]").serialize(),
        success: function (data) {
            console.log(data);
        }
    });
}
</script>

Check that doPost() method of servlet is called from the jsp form and remove conn.commit.

Use this code to pass arraylist<customobj> to anthother Activity

firstly serialize our contact bean

public class ContactBean implements Serializable {
      //do intialization here
}

Now pass your arraylist

 Intent intent = new Intent(this,name of activity.class);
 contactBean=(ConactBean)_arraylist.get(position);
 intent.putExtra("contactBeanObj",conactBean);
 _activity.startActivity(intent);

Adding certificates to Java\jdk\jre\lib\security folder worked for me. If you are using Chrome click on the green bulb [https://support.google.com/chrome/answer/95617?p=ui_security_indicator&rd=1] and save the certificate in security folder.

I had read yesterday that the issue was fixed for someone when that person cleared cookies. I had tried that but it did not work for me.

Checking the following section in DatabaseInterface.class.php,

        define(
            'PMA_MYSQL_INT_VERSION',
            PMA_Util::cacheGet('PMA_MYSQL_INT_VERSION', true)
        );

I figured that somehow cache is the problem. So, I remembered that I was restarting the service instead of doing a start and stop.

# restart the service
systemd restart php-fpm

# start and stop the service
systemd stop php-fpm
systemd start php-fpm

Doing a stop followed by a start fixed the issue for me.

Some answers already pointed out background-size: cover is useful in the case, but none points out the browser support details. Here it is:

Add this CSS into your stylesheet:

body {
    background: url(background.jpg) no-repeat center center fixed;
    background-size: cover; /* for IE9+, Safari 4.1+, Chrome 3.0+, Firefox 3.6+ */
    -webkit-background-size: cover; /* for Safari 3.0 - 4.0 , Chrome 1.0 - 3.0 */
    -moz-background-size: cover; /* optional for Firefox 3.6 */ 
    -o-background-size: cover; /* for Opera 9.5 */
    margin: 0; /* to remove the default white margin of body */
    padding: 0; /* to remove the default white margin of body */
}

-moz-background-size: cover; is optional for Firefox, as Firefox starts supporting the value cover since version 3.6. If you need to support Konqueror 3.5.4+ as well, add -khtml-background-size: cover;.

As you're using CSS3, it's suggested to change your DOCTYPE to HTML5. Also, HTML5 CSS Reset stylesheet is suggested to be added BEFORE your our stylesheet to provide a consistent look & feel for modern browsers.

Reference: background-size at MDN

If you ever need to support old browsers like IE 8 or below, you can still go for Javascript way (scroll down to jQuery section)

Last, if you predict your users will use mobile phones to browse your website, do not use the same background image for mobile web, as your desktop image is probably large in file size, which will be a burden to mobile network usage. Use media query to branch CSS.

Looks to be the same question as:

When an ASP.NET System.Web.HttpResponse.End() is called, the current thread is aborted?

So it's by design. You need to add a catch for that exception and gracefully "ignore" it.

Example: http://bootply.com/103783

One way to achieve this is using a position:fixed container for the background image and place it outside of the .jumbotron. Make the bg container the same height as the .jumbotron and center the background image:

background: url('/assets/example/...jpg') no-repeat center center;

CSS

.bg {
  background: url('/assets/example/bg_blueplane.jpg') no-repeat center center;
  position: fixed;
  width: 100%;
  height: 350px; /*same height as jumbotron */
  top:0;
  left:0;
  z-index: -1;
}

.jumbotron {
  margin-bottom: 0px;
  height: 350px;
  color: white;
  text-shadow: black 0.3em 0.3em 0.3em;
  background:transparent;
}

Then use jQuery to decrease the height of the .jumbtron as the window scrolls. Since the background image is centered in the DIV it will adjust accordingly -- creating a parallax affect.

JavaScript

var jumboHeight = $('.jumbotron').outerHeight();
function parallax(){
    var scrolled = $(window).scrollTop();
    $('.bg').css('height', (jumboHeight-scrolled) + 'px');
}

$(window).scroll(function(e){
    parallax();
});

check String before set another EditText to empty. if Field1 is empty then why need to change again to ( "" )? so you can check the size of Your String with s.lenght() or any other solution

another way that you can check lenght of String is:

String sUsername = Field1.getText().toString();
if (!sUsername.matches(""))
{
// do your job
}

Please set your form action attribute as below it will solve your problem.

<form name="addProductForm" id="addProductForm" action="javascript:;" enctype="multipart/form-data" method="post" accept-charset="utf-8">

$(document).ready(function () {
    $("#addProductForm").submit(function (event) {

        //disable the default form submission
        event.preventDefault();
        //grab all form data  
        var formData = $(this).serialize();

        $.ajax({
            url: 'addProduct.php',
            type: 'POST',
            data: formData,
            async: false,
            cache: false,
            contentType: false,
            processData: false,
            success: function () {
                alert('Form Submitted!');
            },
            error: function(){
                alert("error in ajax form submission");
            }
        });

        return false;
    });
});

Before teaching yourself Spring and Struts, you should probably learn Java. Output like this

org.classes.database.Employee@d9b02

is the result of the Object#toString() method which all objects inherit from the Object class, the superclass of all classes in Java.

The List sub classes implement this by iterating over all the elements and calling toString() on those. It seems, however, that you haven't implemented (overriden) the method in your Employee class.

Your JSTL here

<c:forEach items="${eList}" var="employee">
    <tr>
        <td>Employee ID: <c:out value="${employee.eid}"/></td>
        <td>Employee Pass: <c:out value="${employee.ename}"/></td>  
    </tr>
</c:forEach>

is fine except for the fact that you don't have a page, request, session, or application scoped attribute named eList.

You need to add it

<% List eList = (List)session.getAttribute("empList");
   request.setAttribute("eList", eList);
%>

Or use the attribute empList in the forEach.

<c:forEach items="${empList}" var="employee">
    <tr>
        <td>Employee ID: <c:out value="${employee.eid}"/></td>
        <td>Employee Pass: <c:out value="${employee.ename}"/></td>  
    </tr>
</c:forEach>

Writing this middleware might help !

app.use(function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With,     Content-Type, Accept");
next();
});

In my case, I use nginx as reverse-proxy for an API Gateway URL. I got same error.

I resolved the issue when I added the following two lines to the Nginx config:

proxy_set_header Host "XXXXXX.execute-api.REGION.amazonaws.com";
proxy_ssl_server_name on;

Source is here: Setting up proxy_pass on nginx to make API calls to API Gateway

?php

/* Database config */

$db_host        = 'localhost';
$db_user        = '~';
$db_pass        = '~';
$db_database    = 'banners'; 

/* End config */


$mysqli = new mysqli($db_host, $db_user, $db_pass, $db_database);
/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

?>

These are all good answers, however many forget to close the cursor and database. If you don't close the cursor or database you may run in to memory leaks.

Additionally:
You can get an error when searching by String that contains non alpha/numeric characters. For example: "1a5f9ea3-ec4b-406b-a567-e6927640db40". Those dashes (-) will cause an unrecognized token error. You can overcome this by putting the string in an array. So make it a habit to query like this:

public boolean hasObject(String id) {
    SQLiteDatabase db = getWritableDatabase();
    String selectString = "SELECT * FROM " + _TABLE + " WHERE " + _ID + " =?";

    // Add the String you are searching by here. 
    // Put it in an array to avoid an unrecognized token error 
    Cursor cursor = db.rawQuery(selectString, new String[] {id}); 

    boolean hasObject = false;
    if(cursor.moveToFirst()){
        hasObject = true;

        //region if you had multiple records to check for, use this region. 

        int count = 0;
        while(cursor.moveToNext()){
          count++;
        }
        //here, count is records found
        Log.d(TAG, String.format("%d records found", count));

        //endregion

    } 

    cursor.close();          // Dont forget to close your cursor
    db.close();              //AND your Database!
    return hasObject;
}

According to the create table statement, the default charset of the table is already utf8mb4. It seems that you have a wrong connection charset.

In Java, set the datasource url like this: jdbc:mysql://127.0.0.1:3306/testdb?useUnicode=true&characterEncoding=utf-8.

"?useUnicode=true&characterEncoding=utf-8" is necessary for using utf8mb4.

It works for my application.

After years, I want to add another approach by using a view engine in Express.js

var fs = require('fs');

app.get('/test', function(req, res, next) {
    var html = fs.readFileSync('./html/test.html', 'utf8')
    res.render('test', { html: html })
    // or res.send(html)
})

Then, do that in your views/test if you choose res.render method at the above code (I'm writing in EJS format):

<%- locals.html %>

That's all.

In this way, you don't need to break your View Engine arrangements.

EDIT : 31/10/2017

The same code/approach will work for Asp.Net Core 2.0 as well. The major difference is, In asp.net core, both web api controllers and Mvc controllers are merged together to single controller model. So your return type might be IActionResult or one of it's implementation (Ex :OkObjectResult)

Use

contentType:"application/json"

You need to use JSON.stringify method to convert it to JSON string when you send it,

And the model binder will bind the json data to your class object.

The below code will work fine (tested)

$(function () {
    var customer = {contact_name :"Scott",company_name:"HP"};
    $.ajax({
        type: "POST",
        data :JSON.stringify(customer),
        url: "api/Customer",
        contentType: "application/json"
    });
});

Result

contentType property tells the server that we are sending the data in JSON format. Since we sent a JSON data structure,model binding will happen properly.

If you inspect the ajax request's headers, you can see that the Content-Type value is set as application/json.

If you do not specify contentType explicitly, It will use the default content type which is application/x-www-form-urlencoded;

Edit on Nov 2015 to address other possible issues raised in comments

Posting a complex object

Let's say you have a complex view model class as your web api action method parameter like this

public class CreateUserViewModel
{
   public int Id {set;get;}
   public string Name {set;get;}  
   public List<TagViewModel> Tags {set;get;}
}
public class TagViewModel
{
  public int Id {set;get;}
  public string Code {set;get;}
}

and your web api end point is like

public class ProductController : Controller
{
    [HttpPost]
    public CreateUserViewModel Save([FromBody] CreateUserViewModel m)
    {
        // I am just returning the posted model as it is. 
        // You may do other stuff and return different response.
        // Ex : missileService.LaunchMissile(m);
        return m;
    }
}

At the time of this writing, ASP.NET MVC 6 is the latest stable version and in MVC6, Both Web api controllers and MVC controllers are inheriting from Microsoft.AspNet.Mvc.Controller base class.

To send data to the method from client side, the below code should work fine

//Build an object which matches the structure of our view model class
var model = {
    Name: "Shyju",
    Id: 123,
    Tags: [{ Id: 12, Code: "C" }, { Id: 33, Code: "Swift" }]
};

$.ajax({
    type: "POST",
    data: JSON.stringify(model),
    url: "../product/save",
    contentType: "application/json"
}).done(function(res) {       
    console.log('res', res);
    // Do something with the result :)
});

Model binding works for some properties, but not all ! Why ?

If you do not decorate the web api method parameter with [FromBody] attribute

[HttpPost]
public CreateUserViewModel Save(CreateUserViewModel m)
{
    return m;
}

And send the model(raw javascript object, not in JSON format) without specifying the contentType property value

$.ajax({
    type: "POST",
    data: model,
    url: "../product/save"
}).done(function (res) {
     console.log('res', res);
});

Model binding will work for the flat properties on the model, not the properties where the type is complex/another type. In our case, Id and Name properties will be properly bound to the parameter m, But the Tags property will be an empty list.

The same problem will occur if you are using the short version, $.post which will use the default Content-Type when sending the request.

$.post("../product/save", model, function (res) {
    //res contains the markup returned by the partial view
    console.log('res', res);
});

There are 2 easy ways

• StreamWriter - http://www.dotnetperls.com/streamwriter
• Log4Net like Log4j(Java) - http://www.codeproject.com/Articles/140911/log4net-Tutorial

For Kotlin and bindings the code is:

binding.spinner.onItemSelectedListener = object : AdapterView.OnItemSelectedListener{
            override fun onNothingSelected(parent: AdapterView<*>?) {
            }

            override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {
            }
        }

You should use this library for multi upload in CI https://github.com/stvnthomas/CodeIgniter-Multi-Upload

A very good solution to this can be found here:

Here's a class that serves as a wrapper to a pyserial object. It allows you to read lines without 100% CPU. It does not contain any timeout logic. If a timeout occurs, self.s.read(i) returns an empty string and you might want to throw an exception to indicate the timeout.

It is also supposed to be fast according to the author:

The code below gives me 790 kB/sec while replacing the code with pyserial's readline method gives me just 170kB/sec.

class ReadLine:
    def __init__(self, s):
        self.buf = bytearray()
        self.s = s

    def readline(self):
        i = self.buf.find(b"\n")
        if i >= 0:
            r = self.buf[:i+1]
            self.buf = self.buf[i+1:]
            return r
        while True:
            i = max(1, min(2048, self.s.in_waiting))
            data = self.s.read(i)
            i = data.find(b"\n")
            if i >= 0:
                r = self.buf + data[:i+1]
                self.buf[0:] = data[i+1:]
                return r
            else:
                self.buf.extend(data)

ser = serial.Serial('COM7', 9600)
rl = ReadLine(ser)

while True:

    print(rl.readline())

You have mentioned Wrong id

alert(document.getElementById("name").value);

if you want to use name attribute then

alert(document.getElementsByName("username")[0].value);

Updates:

input type="text" id="name" name="username"  

id is different from name

Use Flowplayer:

<link rel="stylesheet" href="//releases.flowplayer.org/7.0.4/commercial/skin/skin.css">
    <style>

   </style>
   <script src="//code.jquery.com/jquery-1.12.4.min.js"></script>
  <script src="//releases.flowplayer.org/7.0.4/commercial/flowplayer.min.js"></script>
  <script src="//releases.flowplayer.org/hlsjs/flowplayer.hlsjs.min.js"></script> 
  <script>
  flowplayer(function (api) {
    api.on("load", function (e, api, video) {
      $("#vinfo").text(api.engine.engineName + " engine playing " + video.type);
    }); });
  </script>

<div class="flowplayer fixed-controls no-toggle no-time play-button obj"
      style="    width: 85.5%;
    height: 80%;
    margin-left: 7.2%;
    margin-top: 6%;
    z-index: 1000;" data-key="$812975748999788" data-live="true" data-share="false" data-ratio="0.5625"  data-logo="">
      <video autoplay="true" stretch="true">

         <source type="application/x-mpegurl" src="http://live.wmncdn.net/safaritv2/live2.stream/index.m3u8">
      </video>   
   </div>

Different methods are available in flowplayer.org website.

you can add the 1px border to just the sides and bottom of each row. the first value is the top border, the second is the right border, the third is the bottom border, and the fourth is the left border.

div.row {
  border: 0px 1px 1px 1px solid;
}

request.getContextPath()- returns root path of your application, while ../ - returns parent directory of a file.

You use request.getContextPath(), as it will always points to root of your application. If you were to move your jsp file from one directory to another, nothing needs to be changed. Now, consider the second approach. If you were to move your jsp files from one folder to another, you'd have to make changes at every location where you are referring your files.

Also, better approach of using request.getContextPath() will be to set 'request.getContextPath()' in a variable and use that variable for referring your path.

<c:set var="context" value="${pageContext.request.contextPath}" />
<script src="${context}/themes/js/jquery.js"></script>

PS- This is the one reason I can figure out. Don't know if there is any more significance to it.

The following worked for me:

/* function to save JSON to file from browser
* adapted from http://bgrins.github.io/devtools-snippets/#console-save
* @param {Object} data -- json object to save
* @param {String} file -- file name to save to 
*/
function saveJSON(data, filename){

    if(!data) {
        console.error('No data')
        return;
    }

    if(!filename) filename = 'console.json'

    if(typeof data === "object"){
        data = JSON.stringify(data, undefined, 4)
    }

    var blob = new Blob([data], {type: 'text/json'}),
        e    = document.createEvent('MouseEvents'),
        a    = document.createElement('a')

    a.download = filename
    a.href = window.URL.createObjectURL(blob)
    a.dataset.downloadurl =  ['text/json', a.download, a.href].join(':')
    e.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null)
    a.dispatchEvent(e)
}

and then to call it like so

saveJSON(myJsonObject, "saved_data.json");

For the header half of the question, I'm gonna give a shout out to res.type here:

res.type('json')

is equivalent to

res.setHeader('Content-Type', 'application/json')

Source: express docs:

Sets the Content-Type HTTP header to the MIME type as determined by mime.lookup() for the specified type. If type contains the “/” character, then it sets the Content-Type to type.

When autocomplete changes a value, it fires a autocompletechange event, not the change event

$(document).ready(function () {
    $('#tags').on('autocompletechange change', function () {
        $('#tagsname').html('You selected: ' + this.value);
    }).change();
});

Demo: Fiddle

Another solution is to use select event, because the change event is triggered only when the input is blurred

$(document).ready(function () {
    $('#tags').on('change', function () {
        $('#tagsname').html('You selected: ' + this.value);
    }).change();
    $('#tags').on('autocompleteselect', function (e, ui) {
        $('#tagsname').html('You selected: ' + ui.item.value);
    });
});

Demo: Fiddle

It's due to you sending one object, and you're expecting two parameters.

Try this and you'll see:

public class UserDetails
{
   public string username { get; set; }
   public string password { get; set; }
}

public JsonResult Login(UserDetails data)
{
   string error = "";
   //the rest of your code
}

Below code is working on my live server as well as in my own Lapy.

Be aware also if you have declared getters and setters for attributes of the parameter which are not sent in the POST (event if they are not declared in the constructor), for example:

@RestController
public class TestController {

    @RequestMapping(value = "/test", method = RequestMethod.POST)
    public String test(@RequestBody BeanTest beanTest) {
        return "Hello " + beanTest.getName();
    }


    public static class BeanTest {

        private Long id;
        private String name;

        public BeanTest() {
        }

        public BeanTest(Long id) {
            this.id = id;
        }

        public Long getId() {
            return id;
        }

        public void setId(Long id) {
            this.id = id;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }
    }
}

A post request with the next structure: {"id":"1"} would not work, you must delete name get and set.

It looks like this issue has to do with the difference between the Content-Type and Accept headers. In HTTP, Content-Type is used in request and response payloads to convey the media type of the current payload. Accept is used in request payloads to say what media types the server may use in the response payload.

So, having a Content-Type in a request without a body (like your GET request) has no meaning. When you do a POST request, you are sending a message body, so the Content-Type does matter.

If a server is not able to process the Content-Type of the request, it will return a 415 HTTP error. (If a server is not able to satisfy any of the media types in the request Accept header, it will return a 406 error.)

In OData v3, the media type "application/json" is interpreted to mean the new JSON format ("JSON light"). If the server does not support reading JSON light, it will throw a 415 error when it sees that the incoming request is JSON light. In your payload, your request body is verbose JSON, not JSON light, so the server should be able to process your request. It just doesn't because it sees the JSON light content type.

You could fix this in one of two ways:

1. Make the Content-Type "application/json;odata=verbose" in your POST request, or

2. Include the DataServiceVersion header in the request and set it be less than v3. For example:

   DataServiceVersion: 2.0;
   

(Option 2 assumes that you aren't using any v3 features in your request payload.)

I think you want like this, DEMO

var xmlDoc = $.parseXML( xml ); 

var $xml = $(xmlDoc);

var $person = $xml.find("person");

$person.each(function(){

    var name = $(this).find('name').text(),
        age = $(this).find('age').text();

    $("#ProfileList" ).append('<li>' +name+ ' - ' +age+ '</li>');

});

The 500 code would normally indicate an error on the server, not anything with your code. Some thoughts

• Talk to the server developer for more info. You can't get more info directly.
• Verify your arguments into the call (values). Look for anything you might think could cause a problem for the server process. The process should not die and should return you a better code, but bugs happen there also.
• Could be intermittent, like if the server database goes down. May be worth trying at another time.

svg.selectAll("rect")
.attr('x',function(d,i){
    // get x coord
    console.log(this.getBBox().x, 'or', d3.select(this).attr('x'))
})
.attr('y',function(d,i){
    // get y coord
    console.log(this.getBBox().y)
})
.attr('dx',function(d,i){
    // get dx coord
    console.log(parseInt(d3.select(this).attr('dx')))
})

On Windows 10, curl 7.28.1 within powershell, I found the following to work for me:

$filePath = "c:\temp\dir with spaces\myfile.wav"
$curlPath = ("myfilename=@" + $filePath)
curl -v -F $curlPath URL

One problem here is that your method expects int values while you are passing string from ajax call. Try to change it to string and parse inside the webmethod if necessary :

[System.Web.Services.WebMethod]
public static string AddTo_Cart(string quantity, string itemId)
{
    //parse parameters here
    SpiritsShared.ShoppingCart.AddItem(itemId, quantity);      
    return "Add";
}

Edit : or Pass int parameters from ajax call.

I've had same problem, and this is how I fixed it:

Just throw this in your web.config:

<system.webServer>
    <modules>
      <remove name="WebDAVModule" />
    </modules>

    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Expose-Headers " value="WWW-Authenticate"/>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Methods" value="GET, POST, OPTIONS, PUT, PATCH, DELETE" />
        <add name="Access-Control-Allow-Headers" value="accept, authorization, Content-Type" />
        <remove name="X-Powered-By" />
      </customHeaders>
    </httpProtocol>

    <handlers>
      <remove name="WebDAV" />
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <remove name="TRACEVerbHandler" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
</system.webServer>

The problem here is very simple. If you want to display value in JSP, you have to use <%= %> tag instead of <% %>, here is the solved code:

<tr> <td><%=rs.getInt("ID") %></td> <td><%=rs.getString("NAME") %></td> <td><%=rs.getString("SKILL") %></td> </tr>

For me, the problem was passing in a larger than normally expected HTTP header. I resolved it by setting maxHttpHeaderSize="1048576" attribute on the Connector node in server.xml.

function nameInput(limitField)
{
//LimitFile here is a text input and this function is passed to the text 
onInput
var inputString = limitField.value;
// here we capture all illegal chars by adding a ^ inside the class,
// And overwrite them with "".
var newStr = inputString.replace(/[^a-zA-Z-\-\']/g, "");
limitField.value = newStr;
}

This function only allows alphabets, both lower case and upper case and - and ' characters. May help you build yours.

Depending on what you want to accomplish, you might replace INSERT with INSERT IGNORE in your file. This will avoid generating an error for the rows that you are trying to insert and already exist.

See http://dev.mysql.com/doc/refman/5.5/en/insert.html.

May be this problem cause by Gmail account protection. Just click below link and disable security settings.It will work. https://www.google.com/settings/security/lesssecureapps

I Just put CSS in my <div> now working in code

position: relative; top: -22px;

I would recommend you to make use of the $.post or $.get syntax of jQuery for simple cases:

$.post('superman', { field1: "hello", field2 : "hello2"}, 
    function(returnedData){
         console.log(returnedData);
});

If you need to catch the fail cases, just do this:

$.post('superman', { field1: "hello", field2 : "hello2"}, 
    function(returnedData){
         console.log(returnedData);
}).fail(function(){
      console.log("error");
});

Additionally, if you always send a JSON string, you can use $.getJSON or $.post with one more parameter at the very end.

$.post('superman', { field1: "hello", field2 : "hello2"}, 
     function(returnedData){
        console.log(returnedData);
}, 'json');

This example will help you:

<form>
    <input type="button" value="Open Window" onclick="window.open('http://www.google.com')">
</form>

You can open next page on same page by:

<input type="button" value="Open Window" onclick="window.open('http://www.google.com','_self')">

dealing with dates, dateadd must be used for precision

declare @a DATE = getdate()
declare @b time(7) = getdate()
select @b, @A, GETDATE(), DATEADD(day, DATEDIFF(day, 0, @a), cast(@b as datetime2(0)))

I believe this is the best way of doing it, I've tried it and it works very well.

#img {
  object-fit: cover;
}

This is where I found it. Good luck!

for ( i = 0; i < total.length; i++ );
                                    ^-- remove the semi-colon here

With this semi-colon, the loop loops until i == total.length, doing nothing, and then what you thought was the body of the loop is executed.

You can stringify the JSON Object with JSON.stringify(jsonObject) and receive it on controller as String.

In the Controller, you can use the javax.json to convert and manipulate this.

Download and add the .jar to the project libs and import the JsonObject.

To create an json object, you can use

JsonObjectBuilder job = Json.createObjectBuilder();
job.add("header1", foo1);
job.add("header2", foo2);
JsonObject json = job.build();

To read it from String, you can use

JsonReader jr = Json.createReader(new StringReader(jsonString));
JsonObject json = jsonReader.readObject();
jsonReader.close();

I believe you have to reference bootstrap.js before bootstrap-datepicker.js

I just came up with the same problem since we still use bootstrap 2.3.2.

My solution for this: http://jsfiddle.net/KnuU6/281/

css:

.myCollapse {
    display: none;
}
.myCollapse.in {
    display: block;
}

javascript:

 $("[data-toggle=myCollapse]").click(function( ev ) {
   ev.preventDefault();
   var target;
   if (this.hasAttribute('data-target')) {
 target = $(this.getAttribute('data-target'));
   } else {
 target = $(this.getAttribute('href'));
   };
   target.toggleClass("in");
 });

html:

<table>
  <tr><td><a href="#demo" data-toggle="myCollapse">Click me to toggle next row</a></td></tr>
  <tr class="collapse" id="#demo"><td>You can collapse and expand me.</td></tr>
</table>

If you want to add a header to all Jersey responses, you could also use a ContainerResponseFilter, from Jersey's filter documentation :

import java.io.IOException;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerResponseContext;
import javax.ws.rs.container.ContainerResponseFilter;
import javax.ws.rs.core.Response;

@Provider
public class PoweredByResponseFilter implements ContainerResponseFilter {

    @Override
    public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext)
        throws IOException {

            responseContext.getHeaders().add("X-Powered-By", "Jersey :-)");
    }
}

Make sure that you initialize it correctly in your project using the @Provider annotation or through traditional ways with web.xml.

For Microsoft IIS servers, you can enable this header via your web.config file:

<system.webServer>
    <httpProtocol>
      <customHeaders>
        <remove name="X-Content-Type-Options"/>
        <add name="X-Content-Type-Options" value="nosniff"/>
      </customHeaders>
    </httpProtocol>
</system.webServer>

And you are done.

You can get another validation on this tutorial : http://twitterbootstrap.org/bootstrap-form-validation

They use JQuery validation.

jquery.validate.js

jquery.validate.min.js

jquery-1.7.1.min.js

And you'll get the source code there.

 <form id="registration-form" class="form-horizontal">
 <h2>Sample Registration form <small>(Fill up the forms to get register)</small></h2>
 <div class="form-control-group">
        <label class="control-label" for="name">Your Name</label>
 <div class="controls">
          <input type="text" class="input-xlarge" name="name" id="name"></div>
 </div>
 <div class="form-control-group">

<script src="assets/js/jquery.validate.js"></script>

<script src="script.js"></script>
<script>
            addEventListener('load', prettyPrint, false);
            $(document).ready(function(){
            $('pre').addClass('prettyprint linenums');
                  });

happy coding.

PHP - curl:

$username = 'myusername';
$password = 'mypassword';
...
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
...

PHP - POST in WordPress:

$username = 'myusername';
$password = 'mypassword';
...
wp_remote_post('https://...some...api...endpoint...', array(
  'headers' => array(
    'Authorization' => 'Basic ' . base64_encode("$username:$password")
  )
));
...

Try to use this , it works perfectly for me

  // 

   varb = new List<object>();

 // Example 

   varb.Add(new[] { float.Parse(GridView1.Rows[1].Cells[2].Text )});

 // JSON  + Serializ

public string Json()
        {  
            return (new JavaScriptSerializer()).Serialize(varb);
        }


//  Jquery SIDE 

  var datasets = {
            "Products": {
                label: "Products",
                data: <%= getJson() %> 
            }

You are almost certainly running your code before the DOM is constructed. Try running your code in a window.onload handler function (but see note below):

window.onload = function() {
    // all of your code goes in here
    // it runs after the DOM is built
}

Another popular cross-browser solution is to put your <script> block just before the closing </body> tag. This could be the best solution for you, depending on your needs:

<html>
  <body>

    <!-- all of your HTML goes here... -->

    <script>
        // code in this final script element can use all of the DOM
    </script>
  </body>
</html>

• Note that window.onload will wait until all images and subframes have loaded, which might be a long time after the DOM is built. You could also use document.addEventListener("DOMContentLoaded", function(){...}) to avoid this problem, but this is not supported cross-browser. The bottom-of-body trick is both cross-browser and runs as soon as the DOM is complete.

Be careful with your tests. If you in your form you put the same email as the email address which must receive it will be directly in spam :)

Try this way. In your css file change font-family: FontAwesome into font-family: "FontAwesome"; or font-family: 'FontAwesome';. I've solved the same problem using this method.

I've solved my problems, so I post here the correct code in case someone needs similar stuff.

Open Port

int USB = open( "/dev/ttyUSB0", O_RDWR| O_NOCTTY );

Set parameters

struct termios tty;
struct termios tty_old;
memset (&tty, 0, sizeof tty);

/* Error Handling */
if ( tcgetattr ( USB, &tty ) != 0 ) {
   std::cout << "Error " << errno << " from tcgetattr: " << strerror(errno) << std::endl;
}

/* Save old tty parameters */
tty_old = tty;

/* Set Baud Rate */
cfsetospeed (&tty, (speed_t)B9600);
cfsetispeed (&tty, (speed_t)B9600);

/* Setting other Port Stuff */
tty.c_cflag     &=  ~PARENB;            // Make 8n1
tty.c_cflag     &=  ~CSTOPB;
tty.c_cflag     &=  ~CSIZE;
tty.c_cflag     |=  CS8;

tty.c_cflag     &=  ~CRTSCTS;           // no flow control
tty.c_cc[VMIN]   =  1;                  // read doesn't block
tty.c_cc[VTIME]  =  5;                  // 0.5 seconds read timeout
tty.c_cflag     |=  CREAD | CLOCAL;     // turn on READ & ignore ctrl lines

/* Make raw */
cfmakeraw(&tty);

/* Flush Port, then applies attributes */
tcflush( USB, TCIFLUSH );
if ( tcsetattr ( USB, TCSANOW, &tty ) != 0) {
   std::cout << "Error " << errno << " from tcsetattr" << std::endl;
}

Write

unsigned char cmd[] = "INIT \r";
int n_written = 0,
    spot = 0;

do {
    n_written = write( USB, &cmd[spot], 1 );
    spot += n_written;
} while (cmd[spot-1] != '\r' && n_written > 0);

It was definitely not necessary to write byte per byte, also int n_written = write( USB, cmd, sizeof(cmd) -1) worked fine.

At last, read:

int n = 0,
    spot = 0;
char buf = '\0';

/* Whole response*/
char response[1024];
memset(response, '\0', sizeof response);

do {
    n = read( USB, &buf, 1 );
    sprintf( &response[spot], "%c", buf );
    spot += n;
} while( buf != '\r' && n > 0);

if (n < 0) {
    std::cout << "Error reading: " << strerror(errno) << std::endl;
}
else if (n == 0) {
    std::cout << "Read nothing!" << std::endl;
}
else {
    std::cout << "Response: " << response << std::endl;
}

This one worked for me. Thank you all!

If you are using ES6 you can:

var sample = [1, 2, 3]

var result = sample.filter(elem => elem !== 2)

/* output */
[1, 3]

Also take notice filter does not update the existing array it will return a new filtered array every time.

For anyone interested, this one worked for me in Ubuntu:

1. Go to .ssh directory.

   $ cd ~/.ssh
   

2. Remove the known_hosts file.

   $ rm known_hosts
   

3. Re-push your Git changes.

you can use the following to find the posted data.

data = json.loads(request.raw_post_data)

On windows use the name of the table in quotes: TABLE "user"; or SELECT * FROM "user";

Post to the UI thread works for me.

final ImageView iv = (ImageView)findViewById(R.id.scaled_image);

iv.post(new Runnable() {
            @Override

                int width = iv.getMeasuredWidth();
                int height = iv.getMeasuredHeight();

            }
});

I got this error when I had a filename and class exported mismatch:

class exported: ListStudentsComponent

Changing from ListStudentsComponent to ListComponent fixed my issue.

Seems bundler can't use .gem files out of the box. Pointing the :path to a directory containing .gem files doesn't work. Some people suggested to setup a local gem server (geminabox, stickler) for that purpose.

However, what I found to be much simpler is to use a local gem "server" from file system: Just put your .gem files in a local directory, then use "gem generate_index" to make it a Gem repository

mkdir repo
mkdir repo/gems
cp *.gem repo/gems
cd repo
gem generate_index

Finally point bundler to this location by adding the following line to your Gemfile

source "file://path/to/repo"

If you update the gems in the repository, make sure to regenerate the index.

Or this:

$(document).ready(function(){
    $(".header").click(function(){
        $(this).children(".children").toggle();
    });
   $(".header a").click(function(e) {
        return false;
   });
});

session_destroy() is effective after the page load is complete. So in the second upload, the session is terminated. But with unset() you can also log out from within the page.

It may work with any character from the HTML Escape character list, but I had the same problem with a Java project. I used StringEscapeUtils.escapeHTML("Testing \" <br> <p>") and the title was <a href=".." title="Test&quot; &lt;br&gt; &lt;p&gt;">Testing</a>.

It only worked for me when I changed the StringEscapeUtils to StringEscapeUtils.escapeJavascript("Testing \" <br> <p>") and it worked in every browser.

If you run into this issue when running an IIS 8.5 web server you can use the following method.

First, find the "Request Filtering" module in the IIS site you are working on, then double click it...

Next, you need to right click in the white area shown below then click the context menu option called "Edit Feature Settings".

Then the last thing to do is change the "Maximum query string (Bytes)" value from 2048 to something more appropriate such as 5000 for your needs.

This is how we can join two Dataframes on same column names in PySpark.

df = df1.join(df2, ['col1','col2','col3'])

If you do printSchema() after this then you can see that duplicate columns have been removed.

Note: this answer applies only to Angular components and directives, NOT services.

I had this same issue when ngOnInit (and other lifecycle hooks) were not firing for my components, and most searches led me here.

The issue is that I was using the arrow function syntax (=>) like this:

class MyComponent implements OnInit {
    // Bad: do not use arrow function
    public ngOnInit = () => {
        console.log("ngOnInit");
    }
}

Apparently that does not work in Angular 6. Using non-arrow function syntax fixes the issue:

class MyComponent implements OnInit {
    public ngOnInit() {
        console.log("ngOnInit");
    }
}

String-Builder :

int one = 1;
String color = "red";
StringBuilder sb = new StringBuilder();
sb.append("One=").append(one).append(", Color=").append(color).append('\n');
System.out.print(sb);
// Prints "One=1, Colour=red" followed by an ASCII newline.

String-Buffer

StringBuffer sBuffer = new StringBuffer("test");
sBuffer.append(" String Buffer");
System.out.println(sBuffer);  

It is recommended to use StringBuilder whenever possible because it is faster than StringBuffer. However, if the thread safety is necessary, the best option is StringBuffer objects.

Create an xml file any name (say progressBar.xml) in drawable and add <color name="silverGrey">#C0C0C0</color> in color.xml.

Now in your xml file where you have your listView add this code:

You need to concatenate your string.

document.getElementById(tabName).style.backgroundImage = 'url(buttons/' + imagePrefix + '.png)';

The way you had it, it's just making 1 long string and not actually interpreting imagePrefix.

I would even suggest creating the string separate:

function ChangeBackgroungImageOfTab(tabName, imagePrefix)
{
    var urlString = 'url(buttons/' + imagePrefix + '.png)';
    document.getElementById(tabName).style.backgroundImage =  urlString;
}

As mentioned by David Thomas below, you can ditch the double quotes in your string. Here is a little article to get a better idea of how strings and quotes/double quotes are related: http://www.quirksmode.org/js/strings.html

The link here solved my problem.

http://brainof-dave.blogspot.com.au/2008/08/remote-certificate-is-invalid-according.html

I went to url of the web service (on the server that had the issue), clicked on the little security icon in IE, which brought up the certificate. I then clicked on the Details tab, clicked the Copy To File button, which allowed me to export the certifcate as a .cer file. Once I had the certificate locally, I was able to import it into the certificate store on the server using the below instructions.

Start a new MMC. File --> Add/Remove Snap-In... Click Add... Choose Certificates and click Add. Check the "Computer Account" radio button. Click Next.

Choose the client computer in the next screen. Click Finish. Click Close. Click OK. NOW install the certificate into the Trusted Root Certification Authorities certificate store. This will allow all users to trust the certificate.

To detect your controller is pushed or not just use below code in anywhere you want:

if ([[[self.parentViewController childViewControllers] firstObject] isKindOfClass:[self class]]) {

    // Not pushed
}
else {

    // Pushed
}

I hope this code can help anyone...

Based on some comments above below is the code how to remove an object based on a key name and key value

 var items = [ 
  { "id": 3.1, "name": "test 3.1"}, 
  { "id": 22, "name": "test 3.1" }, 
  { "id": 23, "name": "changed test 23" } 
  ]

    function removeByKey(array, params){
      array.some(function(item, index) {
        return (array[index][params.key] === params.value) ? !!(array.splice(index, 1)) : false;
      });
      return array;
    }

    var removed = removeByKey(items, {
      key: 'id',
      value: 23
    });

    console.log(removed);

Port 80

What I do on my cloud instances is I redirect port 80 to port 3000 with this command:

sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3000

Then I launch my Node.js on port 3000. Requests to port 80 will get mapped to port 3000.

You should also edit your /etc/rc.local file and add that line minus the sudo. That will add the redirect when the machine boots up. You don't need sudo in /etc/rc.local because the commands there are run as root when the system boots.

Logs

Use the forever module to launch your Node.js with. It will make sure that it restarts if it ever crashes and it will redirect console logs to a file.

Launch on Boot

Add your Node.js start script to the file you edited for port redirection, /etc/rc.local. That will run your Node.js launch script when the system starts.

Digital Ocean & other VPS

This not only applies to Linode, but Digital Ocean, AWS EC2 and other VPS providers as well. However, on RedHat based systems /etc/rc.local is /ect/rc.d/local.

If you really want to create an array rather than a list use either

String[] names = ["lucas", "Fred", "Mary"]

or

def names = ["lucas", "Fred", "Mary"].toArray()

After the blog post How Can I Use Windows PowerShell to Delete All the .TMP Files on a Drive?, you can use something like this to delete all .tmp for example from a folder and all subfolders in PowerShell:

get-childitem [your path/ or leave empty for current path] -include
*.tmp -recurse | foreach ($_) {remove-item $_.fullname}

#read file lines and edit specific item

file=open("pythonmydemo.txt",'r')
a=file.readlines()
print(a[0][6:11])

a[0]=a[0][0:5]+' Ericsson\n'
print(a[0])

file=open("pythonmydemo.txt",'w')
file.writelines(a)
file.close()
print(a)

You can use $anchorScroll.

Just inject $anchorScroll as a dependency, and call $anchorScroll() whenever you want to scroll to top.

Simply throw Exception if input is invalid

Scanner sc=new Scanner(System.in);
try
{
  System.out.println("Please input an integer");
  //nextInt will throw InputMismatchException
  //if the next token does not match the Integer
  //regular expression, or is out of range
  int usrInput=sc.nextInt();
}
catch(InputMismatchException exception)
{
  //Print "This is not an integer"
  //when user put other than integer
  System.out.println("This is not an integer");
}

Try doing it like this.

User::where('email', $userEmail)
       ->update([
           'member_type' => $plan
        ]);

In order for a percentage value to work for height, the parent's height must be determined. The only exception is the root element <html>, which can be a percentage height. .

So, you've given all of your elements height, except for the <html>, so what you should do is add this:

html {
    height: 100%;
}

And your code should work fine.

* { padding: 0; margin: 0; }_x000D_
html, body, #fullheight {_x000D_
    min-height: 100% !important;_x000D_
    height: 100%;_x000D_
}_x000D_
#fullheight {_x000D_
    width: 250px;_x000D_
    background: blue;_x000D_
}

<div id=fullheight>_x000D_
  Lorem Ipsum        _x000D_
</div>

If you are only looking for a refresh rate for the GOOGLEFINANCE function, keep in mind that data delays can be up to 20 minutes (per Google Finance Disclaimer).

Single-symbol refresh rate (using GoogleClock)

Here is a modified version of the refresh action, taking the data delay into consideration, to save on unproductive refresh cycles.

=GoogleClock(GOOGLEFINANCE(symbol,"datadelay"))

For example, with:

• SYMBOL: GOOG
• DATA DELAY: 15 (minutes)

then

=GoogleClock(GOOGLEFINANCE("GOOG","datadelay"))

Results in a dynamic data-based refresh rate of:

=GoogleClock(15)

Multi-symbol refresh rate (using GoogleClock)

If your sheet contains a number of rows of symbols, you could add a datadelay column for each symbol and use the lowest value, for example:

=GoogleClock(MIN(dataDelayValuesNamedRange))

Where dataDelayValuesNamedRange is the absolute reference or named reference of the range of cells that contain the data delay values for each symbol (assuming these values are different).

Without GoogleClock()

The GoogleClock() function was removed in 2014 and replaced with settings setup for refreshing sheets. At present, I have confirmed that replacement settings is only on available in Sheets from when accessed from a desktop browser, not the mobile app (I'm using Google's mobile Sheets app updated 2016-03-14).

(This part of the answer is based on, and portions copied from, Google Docs Help)

To change how often "some" Google Sheets functions update:

1. Open a spreadsheet. Click File > Spreadsheet settings.
2. In the RECALCULATION section, choose a setting from the drop-down menu.
3. Setting options are:
   • On change
   • On change and every minute
   • On change and every hour
4. Click SAVE SETTINGS.

NOTE External data functions recalculate at the following intervals:

• ImportRange: 30 minutes
• ImportHtml, ImportFeed, ImportData, ImportXml: 1 hour
• GoogleFinance: 2 minutes

The references in earlier sections to the display and use of the datadelay attribute still apply, as well as the concepts for more efficient coding of sheets.

On a positive note, the new refresh option continues to be refreshed by Google servers regardless of whether you have the sheet loaded or not. That's a positive for shared sheets for sure; even more so for Google Apps Scripts (GAS), where GAS is used in workflow code or referenced data is used as a trigger for an event.

[*] in my understanding so far (I am currently testing this)

A workaround may be to try to use -ve values for margins like following:

<Button
    android:id="@+id/button_back"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:onClick="CloseActivity"
    android:padding="0dp"
    android:layout_marginLeft="-5dip"
    android:layout_marginRight="-5dip"
    android:layout_marginTop="-5dip"
    android:layout_marginBottom="-5dip"
    android:text="@string/back" />

It will make that space vanish. I mean you can choose the appropriate dip value, which makes it go away. It worked for me. Hope it works for you.

try to change the size of the image by changing the pixel size from the url in each json object as follows :

With regard to Brent.Longborough's answer (appering only on page 2 onward), perhaps you need to set the \thispagestyle{} after \begin{document}. I wonder if the letter class is setting the first page style to empty.

I found the datetime.isoformat in the documentation. It seems to do what you want:

datetime.isoformat([sep])

Return a string representing the date and time in ISO 8601 format, YYYY-MM-DDTHH:MM:SS.mmmmmm or, if microsecond is 0, YYYY-MM-DDTHH:MM:SS

If utcoffset() does not return None, a 6-character string is appended, giving the UTC offset in (signed) hours and minutes: YYYY-MM-DDTHH:MM:SS.mmmmmm+HH:MM or, if microsecond is 0 YYYY-MM-DDTHH:MM:SS+HH:MM

The optional argument sep (default 'T') is a one-character separator, placed between the date and time portions of the result. For example,
>>>

>>> from datetime import tzinfo, timedelta, datetime
>>> class TZ(tzinfo):
...     def utcoffset(self, dt): return timedelta(minutes=-399)
...
>>> datetime(2002, 12, 25, tzinfo=TZ()).isoformat(' ')
'2002-12-25 00:00:00-06:39'

I fixed it like this example.

$scope.myCalendar = new Date(myUnixDate*1000);
<input date-time ng-model="myCalendar" format="DD/MM/YYYY" />

I had a similar problem with a new ASP.NET Core application a while ago. Turns out one of the referenced libraries used a version of Newtonsoft.Json that was lower than 9.0.0.0. So I upgraded the version for that library and the problem was solved. Not sure if you'll be able to do the same here

The process for timing out an operations is described in the documentation for signal.

The basic idea is to use signal handlers to set an alarm for some time interval and raise an exception once that timer expires.

Note that this will only work on UNIX.

Here's an implementation that creates a decorator (save the following code as timeout.py).

from functools import wraps
import errno
import os
import signal

class TimeoutError(Exception):
    pass

def timeout(seconds=10, error_message=os.strerror(errno.ETIME)):
    def decorator(func):
        def _handle_timeout(signum, frame):
            raise TimeoutError(error_message)

        def wrapper(*args, **kwargs):
            signal.signal(signal.SIGALRM, _handle_timeout)
            signal.alarm(seconds)
            try:
                result = func(*args, **kwargs)
            finally:
                signal.alarm(0)
            return result

        return wraps(func)(wrapper)

    return decorator

This creates a decorator called @timeout that can be applied to any long running functions.

So, in your application code, you can use the decorator like so:

from timeout import timeout

# Timeout a long running function with the default expiry of 10 seconds.
@timeout
def long_running_function1():
    ...

# Timeout after 5 seconds
@timeout(5)
def long_running_function2():
    ...

# Timeout after 30 seconds, with the error "Connection timed out"
@timeout(30, os.strerror(errno.ETIMEDOUT))
def long_running_function3():
    ...

Here is what I'm doing:

git clone repo /tmp/folder
cp -rf /tmp/folder/.git /dest/folder/
cd /dest/folder
git checkout -f master

You can use Cell.Interior.Color, I've used it to count the number of cells in a range that have a given background color (ie. matching my legend).

In modern browsers you can use the Map data structure instead of a object.

A Map object can iterate its elements in insertion order...

It is very simple to adding an image into project and view the image. First create a folder into in your project which can contain any type of images.

Then Right click on Project ->>Go to Build Path ->> configure Build Path ->> add Class folder ->> choose your folder (which you just created for store the images) under the project name.

I had the same problem as the OP except I remembered to declare the ReadOnlyVariables.

After some playing around, I discovered it was the name of my variable that was the issue. "File_Path" in SSIS somehow got converted to "FilePath". C# does not play nicely with underscores in variable names.

So to access the variable, I type

string fp = Variables.FilePath;

In the PreExecute() method of the Script Component.

Here is a simple program that displays the camera feed in a cv2.namedWindow and will take a snapshot when you hit SPACE. It will also quit if you hit ESC.

import cv2

cam = cv2.VideoCapture(0)

cv2.namedWindow("test")

img_counter = 0

while True:
    ret, frame = cam.read()
    if not ret:
        print("failed to grab frame")
        break
    cv2.imshow("test", frame)

    k = cv2.waitKey(1)
    if k%256 == 27:
        # ESC pressed
        print("Escape hit, closing...")
        break
    elif k%256 == 32:
        # SPACE pressed
        img_name = "opencv_frame_{}.png".format(img_counter)
        cv2.imwrite(img_name, frame)
        print("{} written!".format(img_name))
        img_counter += 1

cam.release()

cv2.destroyAllWindows()

I think this should answer your question for the most part. If there is any line of it that you don't understand let me know and I'll add comments.

If you need to grab multiple images per press of the SPACE key, you will need an inner loop or perhaps just make a function that grabs a certain number of images.

Note that the key events are from the cv2.namedWindow so it has to have focus.

In postgresql you can use regular expressions in WHERE clause. Check http://www.postgresql.org/docs/8.4/static/functions-matching.html

MySQL has something simmilar: http://dev.mysql.com/doc/refman/5.5/en/regexp.html

See below example its working

C:/Program Files/PostgreSQL/9.4/bin\pg_restore.exe --host localhost --port 5432 --username "postgres" --dbname "newDatabase" --no-password --verbose

"C:\Users\Yogesh\Downloads\new Download\DB.backup"

If your column is of type DATE (as you say), then you don't need to convert it into a string first (in fact you would convert it implicitly to a string first, then explicitly to a date and again explicitly to a string):

SELECT TO_CHAR(COL1, 'mm/dd/yyyy') FROM TABLE1

The date format your seeing for your column is an artifact of the tool your using (TOAD, SQL Developer etc.) and it's language settings.

@petah and Acrylic DNS Proxy is the best answer, and at the end he references the ability to do multi-site using an Apache which @jeremyasnyder describes a little further down...

... however, in our case we're testing a multi-tenant hosting system and so most domains we want to test go to the same virtualhost, while a couple others are directed elsewhere.

So in our case, you simply use regex wildcards in the ServerAlias directive, like so...

Ok, first launch an ipython shell from the terminal and import TensorFlow:

$ ipython --pylab
Python 3.6.5 |Anaconda custom (64-bit)| (default, Apr 29 2018, 16:14:56) 
Type 'copyright', 'credits' or 'license' for more information
IPython 6.4.0 -- An enhanced Interactive Python. Type '?' for help.
Using matplotlib backend: Qt5Agg

In [1]: import tensorflow as tf

Now, we can watch the GPU memory usage in a console using the following command:

# realtime update for every 2s
$ watch -n 2 nvidia-smi

Since we've only imported TensorFlow but have not used any GPU yet, the usage stats will be:

Notice how the GPU memory usage is very less (~ 700MB); Sometimes the GPU memory usage might even be as low as 0 MB.

Now, let's load the GPU in our code. As indicated in tf documentation, do:

In [2]: sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

Now, the watch stats should show an updated GPU usage memory as below:

Observe now how our Python process from the ipython shell is using ~ 7 GB of the GPU memory.

P.S. You can continue watching these stats as the code is running, to see how intense the GPU usage is over time.

I use http://wiltgen.net/objecty/, it helps to embed media content and avoid the IE "click to activate" problem.

Yes. But as the variable is concerned it is overwrite (Giving new value to variable. Giving new definition to the function is Override). Just don't declare the variable but initialize (change) in the constructor or static block.

The value will get reflected when using in the blocks of parent class

if the variable is static then change the value during initialization itself with static block,

class Son extends Dad {
    static { 
       me = "son"; 
    }
}

or else change in constructor.

You can also change the value later in any blocks. It will get reflected in super class

setState(updater, callback) for useState

Following implementation comes really close to the original setState callback from classes.

Additions made to Robin's solution:

1. Callback execution is omitted on initial render (we want to call it only on state updates)
2. Callback can be dynamic for each setState invocation, like with classes

Usage

const App = () => {
  const [state, setState] = useStateCallback(0); // same API as useState + setState with cb

  const handleClick = () => {
    setState(
      prev => prev + 1,
      // 2nd argument is callback , `s` is *updated* state
      s => console.log("I am called after setState, state:", s)
    );
  };

  return <button onClick={handleClick}>Increment</button>;
}

useStateCallback

function useStateCallback(initialState) {
  const [state, setState] = useState(initialState);
  const cbRef = useRef(null); // mutable ref to store current callback

  const setStateCallback = useCallback((state, cb) => {
    cbRef.current = cb; // store passed callback to ref
    setState(state);
  }, []);

  useEffect(() => {
    // cb.current is `null` on initial render, so we only execute cb on state *updates*
    if (cbRef.current) {
      cbRef.current(state);
      cbRef.current = null; // reset callback after execution
    }
  }, [state]);

  return [state, setStateCallback];
}

Further info: React Hooks FAQ: Is there something like instance variables?

Working example

const App = () => {
  const [state, setState] = useStateCallback(0);

  const handleClick = () =>
    setState(
      prev => prev + 1,
      // important: use `s`, not the stale/old closure value `state`
      s => console.log("I am called after setState, state:", s)
    );

  return (
    <div>
      <p>Hello Comp. State: {state} </p>
      <button onClick={handleClick}>Click me</button>
    </div>
  );
}

function useStateCallback(initialState) {
  const [state, setState] = useState(initialState);
  const cbRef = useRef(null);

  const setStateCallback = useCallback((state, cb) => {
    cbRef.current = cb; 
    setState(state);
  }, []);

  useEffect(() => {
    if (cbRef.current) {
      cbRef.current(state);
      cbRef.current = null;
    }
  }, [state]);

  return [state, setStateCallback];

In MS SQL Server you can do:

SET DATEFORMAT ymd

The method takes a regular expression, not a string, and the dot has a special meaning in regular expressions. Escape it like so split("\\."). You need a double backslash, the second one escapes the first.

PRIMARY KEY CONSTRAINT cannot be altered, you may only drop it and create again. For big datasets it can cause a long run time and thus - table inavailability.

By Java class, I am assuming you mean a Servlet class as setting session attribute in arbitrary Java class does not make sense.You can do something like this in your servlet's doGet/doPost methods

public void doGet(HttpServletRequest request, HttpServletResponse response) {

    HttpSession session = request.getSession();
    String username = (String)request.getAttribute("un");
    session.setAttribute("UserName", username);
}

the data object is a buffer of bytes. Simply call .toString() to get human-readable code:

console.log( data.toString() );

reference: Node.js buffers

The spring data JPA query needs the "%" chars as well as a space char following like in your query, as in

@Query("Select c from Registration c where c.place like %:place%").

Cf. http://docs.spring.io/spring-data/jpa/docs/current/reference/html.

You may want to get rid of the @Queryannotation alltogether, as it seems to resemble the standard query (automatically implemented by the spring data proxies); i.e. using the single line

List<Registration> findByPlaceContaining(String place);

is sufficient.

you can simply identify all changers in the form, like this

           //when form change, show aleart
            $("#FormId").change(function () {
                aleart('Done some change on form');
            }); 

phpmyadmin doesn't follow the MySQL connection because it defines its proper collation in phpmyadmin config file.

So if we don't want or if we can't access server parameters, we should just force it to send results in a different format (encoding) compatible with client i.e. phpmyadmin

for example if both the MySQL connection collation and the MySQL charset are utf8 but phpmyadmin is ISO, we should just add this one before any select query sent to the MYSQL via phpmyadmin :

SET SESSION CHARACTER_SET_RESULTS =latin1;

I had exactly this issue in a recent project which really is a pain in the rear. I finally found it's because the Python we used in Docker has encoding "ansi_x3.4-1968" instead of "utf-8". So if anyone out there using Docker and got this error, following these steps may thoroughly solve your problem.

1. create a file and name it default_locale in the same directory of your Dockerfile, put this line in it,

   environment=LANG="es_ES.utf8", LC_ALL="es_ES.UTF-8", LC_LANG="es_ES.UTF-8"

2. add these to your Dockerfile,

   RUN apt-get clean && apt-get update && apt-get install -y locales

   RUN locale-gen en_CA.UTF-8

   COPY ./default_locale /etc/default/locale

   RUN chmod 0755 /etc/default/locale

   ENV LC_ALL=en_CA.UTF-8

   ENV LANG=en_CA.UTF-8

   ENV LANGUAGE=en_CA.UTF-8

This thoroughly solved my issue when I built and run my Docker again, hopefully this solve your issue also.

to_char(to_date(V_MONTH_NUM,'MM'),'MONTH')

where V_MONTH_NUM is the month number

SELECT to_char(to_date(V_MONTH_NUM,'MM'),'MONTH')  from dual;

1. Jar mismatch comes when you use library projects in your application and both projects are using same jar with different version so just check all library projects attached in your application. if some mismatch exist then remove it.

2. if above process is not working then just do remove project dependency from build path and again add library projects and build the application.

Maybe the following helps you.

Update in ASP.NET Core Version >= 2.0

In the Controller:

public class YourControllerNameController : Controller
{
    private readonly UserManager<ApplicationUser> _userManager;
    
    public YourControllerNameController(UserManager<ApplicationUser> userManager)
    {
        _userManager = userManager;
    }

    public async Task<IActionResult> YourMethodName()
    {
        var userId =  User.FindFirstValue(ClaimTypes.NameIdentifier) // will give the user's userId
        var userName =  User.FindFirstValue(ClaimTypes.Name) // will give the user's userName
        
        // For ASP.NET Core <= 3.1
        ApplicationUser applicationUser = await _userManager.GetUserAsync(User);
        string userEmail = applicationUser?.Email; // will give the user's Email

       // For ASP.NET Core >= 5.0
       var userEmail =  User.FindFirstValue(ClaimTypes.Email) // will give the user's Email
    }
}

In some other class:

public class OtherClass
{
    private readonly IHttpContextAccessor _httpContextAccessor;
    public OtherClass(IHttpContextAccessor httpContextAccessor)
    {
       _httpContextAccessor = httpContextAccessor;
    }

   public void YourMethodName()
   {
      var userId = _httpContextAccessor.HttpContext.User.FindFirstValue(ClaimTypes.NameIdentifier);
   }
}

Then you should register IHttpContextAccessor in the Startup class as follows:

public void ConfigureServices(IServiceCollection services)
{
    services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();

    // Or you can also register as follows

    services.AddHttpContextAccessor();
}

For more readability write extension methods as follows:

public static class ClaimsPrincipalExtensions
{
    public static T GetLoggedInUserId<T>(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        var loggedInUserId = principal.FindFirstValue(ClaimTypes.NameIdentifier);

        if (typeof(T) == typeof(string))
        {
            return (T)Convert.ChangeType(loggedInUserId, typeof(T));
        }
        else if (typeof(T) == typeof(int) || typeof(T) == typeof(long))
        {
            return loggedInUserId != null ? (T)Convert.ChangeType(loggedInUserId, typeof(T)) : (T)Convert.ChangeType(0, typeof(T));
        }
        else
        {
            throw new Exception("Invalid type provided");
        }
    }

    public static string GetLoggedInUserName(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        return principal.FindFirstValue(ClaimTypes.Name);
    }

    public static string GetLoggedInUserEmail(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        return principal.FindFirstValue(ClaimTypes.Email);
    }
}

Then use as follows:

public class YourControllerNameController : Controller
{
    public IActionResult YourMethodName()
    {
        var userId = User.GetLoggedInUserId<string>(); // Specify the type of your UserId;
        var userName = User.GetLoggedInUserName();
        var userEmail = User.GetLoggedInUserEmail();
    }
}

public class OtherClass
{
     private readonly IHttpContextAccessor _httpContextAccessor;
     public OtherClass(IHttpContextAccessor httpContextAccessor)
     {
         _httpContextAccessor = httpContextAccessor;
     }

     public void YourMethodName()
     {
         var userId = _httpContextAccessor.HttpContext.User.GetLoggedInUserId<string>(); // Specify the type of your UserId;
     }
}

You're trying to use key functions with lambda functions.

Python and other languages like C# or F# use lambda functions.

Also, when it comes to key functions and according to the documentation

Both list.sort() and sorted() have a key parameter to specify a function to be called on each list element prior to making comparisons.

...

The value of the key parameter should be a function that takes a single argument and returns a key to use for sorting purposes. This technique is fast because the key function is called exactly once for each input record.

So, key functions have a parameter key and it can indeed receive a lambda function.

In Real Python there's a nice example of its usage. Let's say you have the following list

ids = ['id1', 'id100', 'id2', 'id22', 'id3', 'id30']

and want to sort through its "integers". Then, you'd do something like

sorted_ids = sorted(ids, key=lambda x: int(x[2:])) # Integer sort

and printing it would give

['id1', 'id2', 'id3', 'id22', 'id30', 'id100']

In your particular case, you're only missing to write key= before lambda. So, you'd want to use the following

a = sorted(a, key=lambda x: x.modified, reverse=True)

you need to download and install jdk from here

Global variables that are defined outside of any method or closure can be scope restricted by using the private keyword.

import UIKit

// MARK: Local Constants

private let changeSegueId = "MasterToChange"
private let bookSegueId   = "MasterToBook"

According to this post, it's much better now:

// pick out one album
JObject jalbum = albums[0] as JObject;

// Copy to a static Album instance
Album album = jalbum.ToObject<Album>();

Documentation: Convert JSON to a Type

I use this trick, pretty sure I already posted it to a duplicate of this question:

-(void)tableViewDidLoadRows:(UITableView *)tableView{
    // do something after loading, e.g. select a cell.
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // trick to detect when table view has finished loading.
    [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(tableViewDidLoadRows:) object:tableView];
    [self performSelector:@selector(tableViewDidLoadRows:) withObject:tableView afterDelay:0];

    // specific to your controller
    return self.objects.count;
}

Try this

package main

import "fmt"
import "strconv"

func FloatToString(input_num float64) string {
    // to convert a float number to a string
    return strconv.FormatFloat(input_num, 'f', 6, 64)
}

func main() {
    fmt.Println(FloatToString(21312421.213123))
}

If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg

strconv.FormatFloat(input_num, 'f', -1, 64)

Personally I find fmt easier to use. (Playground link)

fmt.Printf("x = %.6f\n", 21312421.213123)

Or if you just want to convert the string

fmt.Sprintf("%.6f", 21312421.213123)

In swift 3 use this -

object?.addTarget(objectWhichHasMethod, action: #selector(classWhichHasMethod.yourMethod), for: someUIControlEvents)

For example(from my code) -

self.datePicker?.addTarget(self, action:#selector(InfoTableViewCell.datePickerValueChanged), for: .valueChanged)

Just give a : after method name if you want the sender as parameter.

Turn this:

DbCommand command = connection.CreateCommand();
command.CommandText = "SELECT @param";

DbParameter param = command.CreateParameter();
param.ParameterName = "@param";
param.Value = "Hello World";

Answers that claim Django model's Meta and metaclasses are "completely different" are misleading answers.

The construction of Django model class objects, that is to say the object that stands for the class definition itself (yes, classes are also objects), are indeed controlled by a metaclass called ModelBase, and you can see that code here.

And one of the things that ModelBase does is to create the _meta attribute on every Django model which contains validation machinery, field details, save logic and so forth. During this operation, the stuff that is specified in the model's inner Meta class is read and used within that process.

So, while yes, in a sense Meta and metaclasses are different 'things', within the mechanics of Django model construction they are intimately related; understanding how they work together will deepen your insight into both at once.

This might be a helpful source of information to better understand how Django models employ metaclasses.

https://code.djangoproject.com/wiki/DevModelCreation

And this might help too if you want to better understand how objects work in general.

I think this suits perfect for any color you have:

a {
    color: inherit;
}

You can use inner divs to set the margin.

<div style="display: table-cell;">
   <div style="margin:5px;background-color: red;">1</div>
</div>
<div style="display: table-cell; ">
  <div style="margin:5px;background-color: green;">1</div>
</div>

JS Fiddle

Not 100% sure as the question is missing some details but if you are using JAX-WS RI, then have a look at Adding SOAP headers when sending requests:

The portable way of doing this is that you create a SOAPHandler and mess with SAAJ, but the RI provides a better way of doing this.

When you create a proxy or dispatch object, they implement BindingProvider interface. When you use the JAX-WS RI, you can downcast to WSBindingProvider which defines a few more methods provided only by the JAX-WS RI.

This interface lets you set an arbitrary number of Header object, each representing a SOAP header. You can implement it on your own if you want, but most likely you'd use one of the factory methods defined on Headers class to create one.

import com.sun.xml.ws.developer.WSBindingProvider;

HelloPort port = helloService.getHelloPort();  // or something like that...
WSBindingProvider bp = (WSBindingProvider)port;

bp.setOutboundHeader(
  // simple string value as a header, like <simpleHeader>stringValue</simpleHeader>
  Headers.create(new QName("simpleHeader"),"stringValue"),
  // create a header from JAXB object
  Headers.create(jaxbContext,myJaxbObject)
);

Update your code accordingly and try again. And if you're not using JAX-WS RI, please update your question and provide more context information.

Update: It appears that the web service you want to call is secured with WS-Security/UsernameTokens. This is a bit different from your initial question. Anyway, to configure your client to send usernames and passwords, I suggest to check the great post Implementing the WS-Security UsernameToken Profile for Metro-based web services (jump to step 4). Using NetBeans for this step might ease things a lot.

This is a guaranteed way to get it done in Vanilla (or simply Pure) JavaScript:

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

Adding my bit as this is a popular question.

I couldn't place .history directory inside .gitignore because no matter what combo I tried, it just didn't work. Windows keeps generating new files upon every save and I don't want to see these at all.

But then I realized, this is just my personal development environment on my machine. Things like .history or .vscode are specific for me so it would be weird if everyone included their own .gitignore entries based on what IDE or OS they are using.

So this worked for me, just append ".history" to .git/info/exclude

echo ".history" >> .git/info/exclude

Is there a step missing?

Yes. You need to create the directory:

mkdir ${HOME}/.ssh

Additionally, SSH requires you to set the permissions so that only you (the owner) can access anything in ~/.ssh:

% chmod 700 ~/.ssh

Should the .ssh dir be generated when I use the ssh-keygen command?

No. This command generates an SSH key pair but will fail if it cannot write to the required directory:

% ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/xxx/.ssh/id_rsa): /Users/tmp/does_not_exist
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
open /Users/tmp/does_not_exist failed: No such file or directory.
Saving the key failed: /Users/tmp/does_not_exist.

Once you've created your keys, you should also restrict who can read those key files to just yourself:

% chmod -R go-wrx ~/.ssh/*

You can try a simple kernel and the filter2D function, e.g. in Python:

kernel = np.array([[-1,-1,-1], [-1,9,-1], [-1,-1,-1]])
im = cv2.filter2D(im, -1, kernel)

Wikipedia has a good overview of kernels with some more examples here - https://en.wikipedia.org/wiki/Kernel_(image_processing)

In image processing, a kernel, convolution matrix, or mask is a small matrix. It is used for blurring, sharpening, embossing, edge detection, and more. This is accomplished by doing a convolution between a kernel and an image.

to accomplish what you want, you must getPaths from the polygon. Paths will be an array of LatLng points. you get the elements of the array and split the LatLng pairs with the methods .lat and .lng in the function below, i have a redundant array corresponding to a polyline that marks the perimeter around the polygon.

saving is another story. you can then opt for many methods. you may save your list of points as a csv formatted string and export that to a file (easiest solution, by far). i highly recommend GPS TXT formats, like the ones (there are 2) readable by GPS TRACKMAKER (great free version software). if you are competent to save them to a database, that is a great solution (i do both, for redundancy).

function areaPerimeterParse(areaPerimeterPath) {
    var flag1stLoop = true;
    var areaPerimeterPathArray = areaPerimeterPath.getPath();
    var markerListParsedTXT = "Datum,WGS84,WGS84,0,0,0,0,0\r\n";

    var counter01 = 0;
    var jSpy = "";
    for (var j = 0;j<areaPerimeterPathArray.length;j++) {
        counter01++;
        jSpy += j+"  ";
        if (flag1stLoop) {
            markerListParsedTXT += 'TP,D,'+[ areaPerimeterPathArray.getAt(j).lat(), areaPerimeterPathArray.getAt(j).lng()].join(',')+',00/00/00,00:00:00,1'+'\r\n';
            flag1stLoop = false;
        } else {
            markerListParsedTXT += 'TP,D,'+[ areaPerimeterPathArray.getAt(j).lat(), areaPerimeterPathArray.getAt(j).lng()].join(',')+',00/00/00,00:00:00,0'+'\r\n';
        }

    }
    // last point repeats first point
    markerListParsedTXT += 'TP,D,'+[ areaPerimeterPathArray.getAt(0).lat(), areaPerimeterPathArray.getAt(0).lng()].join(',')+',00/00/00,00:00:00,0'+'\r\n';
    return markerListParsedTXT;
}

attention, the line that ends with ",1" (as opposed to ",0") starts a new polygon (this format allows you to save multiple polygons in the same file). i find TXT more human readable than the XML based formats GPX and KML.

You could use jQuery's grep method:

$.grep(carBrands, function(obj) { return obj.name == "ford"; });

But as you specify no jQuery, you could just make a derivative of the function. From the source code:

function grepArray( elems, callback, inv ) {  
    var ret = [];  

    // Go through the array, only saving the items  
    // that pass the validator function  
    for ( var i = 0, length = elems.length; i < length; i++ ) {  
        if ( !inv !== !callback( elems[ i ], i ) ) {  
            ret.push( elems[ i ] );  
        }  
    }  

    return ret;  
}  

grepArray(carBrands, function(obj) { return obj.name == "ford"; });

You can't, but... If you own both pages then...

1) You can send the data via query params (http://siteB.com/?key=value)

2) You can create an iframe of Site B inside site A and you can send post messages from one place to the other. As Site B is the owner of site B cookies it will be able to set whatever value you need by processing the correct post message. (You should prevent other unwanted senders to send messages to you! that is up to you and the mechanism you decide to use to prevent that from happening)

Here is a nice tutorial, it is what you need. (Source: coursesweb.net/php-mysql)

Register and show online users and visitors

Count Online users and visitors using a MySQL table

In this tutorial you can learn how to register, to count, and display in your webpage the number of online users and visitors. The principle is this: each user / visitor is registered in a text file or database. Every time a page of the website is accessed, the php script deletes all records older than a certain time (eg 2 minutes), adds the current user / visitor and takes the number of records left to display.

You can store the online users and visitors in a file on the server, or in a MySQL table. In this case, I think that using a text file to add and read the records is faster than storing them into a MySQL table, which requires more requests.

First it's presented the method with recording in a text file on the server, than the method with MySQL table.

To download the files with the scripts presented in this tutorial, click -> Count Online Users and Visitors.

• Both scripts can be included in ".php" files (with include()), or in ".html" files (with <script>), as you can see in the examples presented at the bottom of this page; but the server must run PHP.

Storing online users and visitors in a text file

To add records in a file on the server with PHP you must set CHMOD 0766 (or CHMOD 0777) permissions to that file, so the PHP can write data in it.

1. Create a text file on your server (for example, named userson.txt) and give it CHMOD 0777 permissions (in your FTP application, right click on that file, choose Properties, then select Read, Write, and Execute options).
2. Create a PHP file (named usersontxt.php) having the code below, then copy this php file in the same directory as userson.txt.

The code for usersontxt.php;

<?php
// Script Online Users and Visitors - http://coursesweb.net/php-mysql/
if(!isset($_SESSION)) session_start();        // start Session, if not already started

$filetxt = 'userson.txt';  // the file in which the online users /visitors are stored
$timeon = 120;             // number of secconds to keep a user online
$sep = '^^';               // characters used to separate the user name and date-time
$vst_id = '-vst-';        // an identifier to know that it is a visitor, not logged user

/*
 If you have an user registration script,
 replace $_SESSION['nume'] with the variable in which the user name is stored.
 You can get a free registration script from:  http://coursesweb.net/php-mysql/register-login-script-users-online_s2
*/

// get the user name if it is logged, or the visitors IP (and add the identifier)

    $uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $_SERVER['SERVER_ADDR']. $vst_id;

$rgxvst = '/^([0-9\.]*)'. $vst_id. '/i';         // regexp to recognize the line with visitors
$nrvst = 0;                                       // to store the number of visitors

// sets the row with the current user /visitor that must be added in $filetxt (and current timestamp)

    $addrow[] = $uvon. $sep. time();

// check if the file from $filetxt exists and is writable

    if(is_writable($filetxt)) {
      // get into an array the lines added in $filetxt
      $ar_rows = file($filetxt, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
      $nrrows = count($ar_rows);

            // number of rows

  // if there is at least one line, parse the $ar_rows array

      if($nrrows>0) {
        for($i=0; $i<$nrrows; $i++) {
          // get each line and separate the user /visitor and the timestamp
          $ar_line = explode($sep, $ar_rows[$i]);
      // add in $addrow array the records in last $timeon seconds
          if($ar_line[0]!=$uvon && (intval($ar_line[1])+$timeon)>=time()) {
            $addrow[] = $ar_rows[$i];
          }
        }
      }
    }

$nruvon = count($addrow);                   // total online
$usron = '';                                    // to store the name of logged users
// traverse $addrow to get the number of visitors and users
for($i=0; $i<$nruvon; $i++) {
 if(preg_match($rgxvst, $addrow[$i])) $nrvst++;       // increment the visitors
 else {
   // gets and stores the user's name
   $ar_usron = explode($sep, $addrow[$i]);
   $usron .= '<br/> - <i>'. $ar_usron[0]. '</i>';
 }
}
$nrusr = $nruvon - $nrvst;              // gets the users (total - visitors)

// the HTML code with data to be displayed
$reout = '<div id="uvon"><h4>Online: '. $nruvon. '</h4>Visitors: '. $nrvst. '<br/>Users: '. $nrusr. $usron. '</div>';

// write data in $filetxt
if(!file_put_contents($filetxt, implode("\n", $addrow))) $reout = 'Error: Recording file not exists, or is not writable';

// if access from <script>, with GET 'uvon=showon', adds the string to return into a JS statement
// in this way the script can also be included in .html files
if(isset($_GET['uvon']) && $_GET['uvon']=='showon') $reout = "document.write('$reout');";

echo $reout;             // output /display the result
?>

3. If you want to include the script above in a ".php" file, add the following code in the place you want to show the number of online users and visitors:

4.To show the number of online visitors /users in a ".html" file, use this code:

<script type="text/javascript" src="usersontxt.php?uvon=showon"></script>

This script (and the other presented below) works with $_SESSION. At the beginning of the PHP file in which you use it, you must add: session_start();. Count Online users and visitors using a MySQL table

To register, count and show the number of online visitors and users in a MySQL table, require to perform three SQL queries: Delete the records older than a certain time. Insert a row with the new user /visitor, or, if it is already inserted, Update the timestamp in its column. Select the remaining rows. Here's the code for a script that uses a MySQL table (named "userson") to store and display the Online Users and Visitors.

1. First we create the "userson" table, with 2 columns (uvon, dt). In the "uvon" column is stored the name of the user (if logged in) or the visitor's IP. In the "dt" column is stored a number with the timestamp (Unix time) when the page is accessed.

• Add the following code in a php file (for example, named "create_userson.php"):

The code for create_userson.php:

<?php
header('Content-type: text/html; charset=utf-8');

// HERE add your data for connecting to MySQ database
$host = 'localhost';           // MySQL server address
$user = 'root';                // User name
$pass = 'password';            // User`s password
$dbname = 'database';          // Database name

// connect to the MySQL server
$conn = new mysqli($host, $user, $pass, $dbname);

// check connection
if (mysqli_connect_errno()) exit('Connect failed: '. mysqli_connect_error());

// sql query for CREATE "userson" TABLE
$sql = "CREATE TABLE `userson` (
 `uvon` VARCHAR(32) PRIMARY KEY,
 `dt` INT(10) UNSIGNED NOT NULL
 ) CHARACTER SET utf8 COLLATE utf8_general_ci"; 

// Performs the $sql query on the server to create the table
if ($conn->query($sql) === TRUE) echo 'Table "userson" successfully created';
else echo 'Error: '. $conn->error;

$conn->close();
?>

2. Now we create the script that Inserts, Deletes, and Selects data in the userson table (For explanations about the code, see the comments in script).

• Add the code below in another php file (named usersmysql.php): In both file you must add your personal data for connecting to MySQL database, in the variables: $host, $user, $pass, and $dbname .

The code for usersmysql.php:

<?php
// Script Online Users and Visitors - coursesweb.net/php-mysql/
if(!isset($_SESSION)) session_start();         // start Session, if not already started

// HERE add your data for connecting to MySQ database
$host = 'localhost';           // MySQL server address
$user = 'root';                // User name
$pass = 'password';            // User`s password
$dbname = 'database';          // Database name

/*
 If you have an user registration script,
 replace $_SESSION['nume'] with the variable in which the user name is stored.
 You can get a free registration script from:  http://coursesweb.net/php-mysql/register-login-script-users-online_s2
*/

// get the user name if it is logged, or the visitors IP (and add the identifier)
$vst_id = '-vst-';         // an identifier to know that it is a visitor, not logged user
$uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $_SERVER['SERVER_ADDR']. $vst_id;

$rgxvst = '/^([0-9\.]*)'. $vst_id. '/i';         // regexp to recognize the rows with visitors
$dt = time();                                    // current timestamp
$timeon = 120;             // number of secconds to keep a user online
$nrvst = 0;                                     // to store the number of visitors
$nrusr = 0;                                     // to store the number of usersrs
$usron = '';                                    // to store the name of logged users

// connect to the MySQL server
$conn = new mysqli($host, $user, $pass, $dbname);

// Define and execute the Delete, Insert/Update, and Select queries
$sqldel = "DELETE FROM `userson` WHERE `dt`<". ($dt - $timeon);
$sqliu = "INSERT INTO `userson` (`uvon`, `dt`) VALUES ('$uvon', $dt) ON DUPLICATE KEY UPDATE `dt`=$dt";
$sqlsel = "SELECT * FROM `userson`";

// Execute each query
if(!$conn->query($sqldel)) echo 'Error: '. $conn->error;
if(!$conn->query($sqliu)) echo 'Error: '. $conn->error;
$result = $conn->query($sqlsel);

// if the $result contains at least one row
if ($result->num_rows > 0) {
  // traverse the sets of results and set the number of online visitors and users ($nrvst, $nrusr)
  while($row = $result->fetch_assoc()) {
    if(preg_match($rgxvst, $row['uvon'])) $nrvst++;       // increment the visitors
    else {
      $nrusr++;                   // increment the users
      $usron .= '<br/> - <i>'.$row['uvon']. '</i>';          // stores the user's name
    }
  }
}

$conn->close();                  // close the MySQL connection

// the HTML code with data to be displayed
$reout = '<div id="uvon"><h4>Online: '. ($nrusr+$nrvst). '</h4>Visitors: '. $nrvst. '<br/>Users: '. $nrusr. $usron. '</div>';

// if access from <script>, with GET 'uvon=showon', adds the string to return into a JS statement
// in this way the script can also be included in .html files
if(isset($_GET['uvon']) && $_GET['uvon']=='showon') $reout = "document.write('$reout');";

echo $reout;             // output /display the result
?>

3. After you have created these two php files on your server, run the "create_userson.php" on your browser to create the "userson" table.

4. Include the usersmysql.php file in the php file in which you want to display the number of online users and visitors.

5. Or, if you want to insert it in a ".html" file, add this code:

Examples using these scripts

• Including the "usersontxt.php` in a php file:

<!doctype html>

• Including the "usersmysql.php" in a html file:

<!doctype html>
<html>
<head>
 <meta charset="utf-8" />
 <title>Counter Online Users and Visitors</title>
 <meta name="description" content="PHP script to count and show the number of online users and visitors" />
 <meta name="keywords" content="online users, online visitors" />
</head>
<body>

<!-- Includes the script ("usersontxt.php", or "usersmysql.php") -->
<script type="text/javascript" src="usersmysql.php?uvon=showon"></script>

</body>
</html>

Both scripts (with storing data in a text file on the server, or into a MySQL table) will display a result like this: Online: 5

Visitors: 3 Users: 2

Presumably you have it in a variable and are using JSON.parse(data);. In which case, use:

JSON.parse(data.replace(/"/g,'"'));

You might want to fix your JSON-writing script though, because " is not valid in a JSON object.

All of the above seem to assume you know the URL for the latest Java RPM...

Oracle provide persistent links to the latest updates of each Java version as documented at https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=397248601136938&id=1414485.1 - though you need to create/log in to an Oracle Support account. *Otherwise you can only access the last "public" update of each Java version, e.g. 1.6_u45 (Mar 2013; Latest update is u65, Oct 2013)*

Once you know the persistent link, you should be able to resolve it to the real download; The following works for me, though I don't yet know if the "aru" reference changes.

ME=<myOracleID>
PW=<myOraclePW>
PATCH_FILE=p13079846_17000_Linux-x86-64.zip

echo "Get real URL from the persistent link"

wget -o getrealurl.out --no-cookies --no-check-certificate --user=$ME \
--password=$PW --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com" \
https://updates.oracle.com/Orion/Services/download/$PATCH_FILE?aru=16884382&\
patch_file=$PATCH_FILE

wait    # wget appears to go into background, so "wait" waits 
        # until all background processes complete

REALURL=`grep "^--" getrealurl.out |tail -1 |sed -e 's/.*http/http/'`
wget -O $PATCH_FILE $REALURL
#These last steps must be done quickly, as the REALURL seems to have a short-lived 
#cookie on it and I've had no success with  --keep-session-cookies etc.

Make the area with your data and formulas a Table:

Then adding new information in the next line will copy all formulas in that table for the new line. Data validation will also be applied for the new row as it was for the whole column. This is indeed Excel being smarter with your data.

NO VBA required...

ResponseEntity is meant to represent the entire HTTP response. You can control anything that goes into it: status code, headers, and body.

@ResponseBody is a marker for the HTTP response body and @ResponseStatus declares the status code of the HTTP response.

@ResponseStatus isn't very flexible. It marks the entire method so you have to be sure that your handler method will always behave the same way. And you still can't set the headers. You'd need the HttpServletResponse or a HttpHeaders parameter.

Basically, ResponseEntity lets you do more.

For the folks that like me got here because they're trying to host aspnet.core mvc in a console application: The ONLY way I was able to solve this was by converting the .csproj to the new format and add the Sdk property to the Project tag on the very first line.

<Project Sdk="Microsoft.NET.Sdk.Razor">

Go into Tools -> Options -> Designers-> Uncheck "Prevent saving changes that require table re-creation". Voila.

That happens because sometimes it is necessary to drop and recreate a table in order to change something. This can take a while, since all data must be copied to a temp table and then re-inserted in the new table. Since SQL Server by default doesn't trust you, you need to say "OK, I know what I'm doing, now let me do my work."

PATH is an environment variable, and can be displayed with the echo command:

echo $PATH

It's a list of paths separated by the colon character ':'

The which command tells you which file gets executed when you run a command:

which lshw

sometimes what you get is a path to a symlink; if you want to trace that link to where the actual executable lives, you can use readlink and feed it the output of which:

readlink -f $(which lshw)

The -f parameter instructs readlink to keep following the symlink recursively.

Here's an example from my machine:

$ which firefox
/usr/bin/firefox

$ readlink -f $(which firefox)
/usr/lib/firefox-3.6.3/firefox.sh

attributes are in your HTML text document/file (== imagine this is the result of your html markup parsed), whereas
properties are in HTML DOM tree (== basically an actual property of some object in JS sense).

Importantly, many of them are synced (if you update class property, class attribute in html will also be updated; and otherwise). But some attributes may be synced to unexpected properties - eg, attribute checked corresponds to property defaultChecked, so that

• manually checking a checkbox will change .prop('checked') value, but will not change .attr('checked') and .prop('defaultChecked') values
• setting $('#input').prop('defaultChecked', true) will also change .attr('checked'), but this will not be visible on an element.

Rule of thumb is: .prop() method should be used for boolean attributes/properties and for properties which do not exist in html (such as window.location). All other attributes (ones you can see in the html) can and should continue to be manipulated with the .attr() method. (http://blog.jquery.com/2011/05/10/jquery-1-6-1-rc-1-released/)

And here is a table that shows where .prop() is preferred (even though .attr() can still be used).

Why would you sometimes want to use .prop() instead of .attr() where latter is officially adviced?

1. .prop() can return any type - string, integer, boolean; while .attr() always returns a string.
2. .prop() is said to be about 2.5 times faster than .attr().

inet_ntoa() converts a in_addr to string:

The inet_ntoa function converts an (Ipv4) Internet network address into an ASCII string in Internet standard dotted-decimal format.

inet_addr() does the reverse job

The inet_addr function converts a string containing an IPv4 dotted-decimal address into a proper address for the IN_ADDR structure

PS this the first result googling "in_addr to string"!

Try this command:

find / -name file.look

They are not doing the same job: $emit dispatches an event upwards through the scope hierarchy, while $broadcast dispatches an event downwards to all child scopes.

The full answer

1. The default (fresh install of tomcat)

When you download tomcat from their official website (of today that's tomcat version 9.0.26), all the apps you installed to tomcat can handle HTTP requests of unlimited size, given that the apps themselves do not have any limits on request size.

However, when you try to upload an app in tomcat's manager app, that app has a default war file limit of 50MB. If you're trying to install Jenkins for example which is 77 MB as ot today, it will fail.

2. Configure tomcat's per port http request size limit

Tomcat itself has size limit for each port, and this is defined in conf\server.xml. This is controlled by maxPostSize attribute of each Connector(port). If this attribute does not exist, which it is by default, there is no limit on the request size.

To add a limit to a specific port, set a byte size for the attribute. For example, the below config for the default 8080 port limits request size to 200 MB. This means that all the apps installed under port 8080 now has the size limit of 200MB

<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443"
           maxPostSize="209715200" />

3. Configure app level size limit

After passing the port level size limit, you can still configure app level limit. This also means that app level limit should be less than port level limit. The limit can be done through annotation within each servlet, or in the web.xml file. Again, if this is not set at all, there is no limit on request size.

To set limit through java annotation

@WebServlet("/uploadFiles")
@MultipartConfig( fileSizeThreshold = 0, maxFileSize = 209715200, maxRequestSize = 209715200)
public class FileUploadServlet extends HttpServlet {

    public void doPost(HttpServletRequest request, HttpServletResponse response) {
        // ...
    }
}

To set limit through web.xml

<web-app>
  ...
  <servlet>
    ...

4. Appendix - If you see file upload size error when trying to install app through Tomcat's Manager app

Tomcat's Manager app (by default localhost:8080/manager) is nothing but a default web app. By default that app has a web.xml configuration of request limit of 50MB. To install (upload) app with size greater than 50MB through this manager app, you have to change the limit. Open the manager app's web.xml file from webapps\manager\WEB-INF\web.xml and follow the above guide to change the size limit and finally restart tomcat.

For example string s="(U+007c)"

To remove only the parentheses from s, try the below one:

import re
a=re.sub("\\(","",s)
b=re.sub("\\)","",a)
print(b)

try this

json = $.grep(newcurrPayment.paymentTypeInsert, function (el, idx) { return el.FirstName == "Test1" }, true)

you need to make county_ID as index for the right frame:

frame_2.join ( frame_1.set_index( [ 'county_ID' ], verify_integrity=True ),
               on=[ 'countyid' ], how='left' )

for your information, in pandas left join breaks when the right frame has non unique values on the joining column. see this bug.

so you need to verify integrity before joining by , verify_integrity=True

For an unknow reason, the accepted answer partially works when I send email to my gmail address. I have the attachement but not the text of the email.

If you want both attachment and text try this based on the accepted answer :

    Properties props = new java.util.Properties();
    props.put("mail.smtp.host", "yourHost");
    props.put("mail.smtp.port", "yourHostPort");
    props.put("mail.smtp.auth", "true");             
    props.put("mail.smtp.starttls.enable", "true");


    // Session session = Session.getDefaultInstance(props, null);
    Session session = Session.getInstance(props,
              new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication("user", "password");
                }
              });


    Message msg = new MimeMessage(session);
    try {
        msg.setFrom(new InternetAddress(mailFrom));
        msg.setRecipient(Message.RecipientType.TO, new InternetAddress(mailTo));
        msg.setSubject("your subject");

        Multipart multipart = new MimeMultipart();

        MimeBodyPart textBodyPart = new MimeBodyPart();
        textBodyPart.setText("your text");

        MimeBodyPart attachmentBodyPart= new MimeBodyPart();
        DataSource source = new FileDataSource(attachementPath); // ex : "C:\\test.pdf"
        attachmentBodyPart.setDataHandler(new DataHandler(source));
        attachmentBodyPart.setFileName(fileName); // ex : "test.pdf"

        multipart.addBodyPart(textBodyPart);  // add the text part
        multipart.addBodyPart(attachmentBodyPart); // add the attachement part

        msg.setContent(multipart);


        Transport.send(msg);
    } catch (MessagingException e) {
        LOGGER.log(Level.SEVERE,"Error while sending email",e);
    }

Update :

If you want to send a mail as an html content formated you have to do

    MimeBodyPart textBodyPart = new MimeBodyPart();
    textBodyPart.setContent(content, "text/html");

So basically setText is for raw text and will be well display on every server email including gmail, setContent is more for an html template and if you content is formatted as html it will maybe also works in gmail

If you don't mind leaving pure C# and going for WinApi calls, then you might want to consider the PathIsDirectoryEmpty() function. According to the MSDN, the function:

Returns TRUE if pszPath is an empty directory. Returns FALSE if pszPath is not a directory, or if it contains at least one file other than "." or "..".

That seems to be a function which does exactly what you want, so it is probably well optimised for that task (although I haven't tested that).

To call it from C#, the pinvoke.net site should help you. (Unfortunately, it doesn't describe this certain function yet, but you should be able to find some functions with similar arguments and return type there and use them as the basis for your call. If you look again into the MSDN, it says that the DLL to import from is shlwapi.dll)

One pitfall I ran into was a parent element having the 'overflow' attribute set to 'auto'. This negates child div elements with the page-break-inside attribute in the print version. Otherwise, page-break-inside: avoid works fine on Chrome for me.

In javascript you can do something like this

<input
  ref="fileInput"
  multiple
  type="file"
  style="display: none"
  @change="trySubmitFile"
>

and the function can be something like this.

trySubmitFile(e) {
  if (this.disabled) return;
  const files = e.target.files || e.dataTransfer.files;
  if (files.length > 5) {
    alert('You are only allowed to upload a maximum of 2 files at a time');
  }
  if (!files.length) return;
  for (let i = 0; i < Math.min(files.length, 2); i++) {
    this.fileCallback(files[i]);
  }
}

I am also searching for a solution where this can be limited at the time of selecting files but until now I could not find anything like that.

Would the following Macro help you?

Sub activateSheet(sheetname As String)
'activates sheet of specific name
    Worksheets(sheetname).Activate
End Sub

Basically you want to make use of the .Activate function. Or you can use the .Select function like so:

Sub activateSheet(sheetname As String)
'selects sheet of specific name
    Sheets(sheetname).Select
End Sub

I have similar requirement where I need a MySQL client but not server (running in a virtual machine and don't want any additional overhead) and for me the easiest thing was to install MySQL community server taking typical installation options but NOT configure the server, so it never starts, never runs. Added C:\Program Files (x86)\MySQL\MySQL Server 5.5\bin to system path environment variable and I'm able to use the MySQL command line client mssql.exe and mysqladmin.exe programs.

Try this. The following considers checkbox and label as a unique element:

<style>
  .item {white-space: nowrap;display:inline  }
</style>
<fieldset>
<div class="item">
    <input type="checkbox" id="a">
    <label for="a">aaaaaaaaaaaa aaaa a a a a a a aaaaaaaaaaaaa</label>
</div>
<div class="item">
   <input type="checkbox" id="b">
<!-- depending on width, a linebreak NEVER occurs here. -->
    <label for="b">bbbbbbbbbbbb bbbbbbbbbbbbbbbbb  b b b b  bb</label>
</div>
<div class="item">
    <input type="checkbox" id="c">
    <label for="c">ccccc c c c c ccccccccccccccc  cccc</label>
</div>
</fieldset>

This is how you Delete From a slice the idiomatic way. You don't need to build a function it is built into the append. Try it here https://play.golang.org/p/QMXn9-6gU5P

z := []int{9, 8, 7, 6, 5, 3, 2, 1, 0}
fmt.Println(z)  //will print Answer [9 8 7 6 5 3 2 1 0]

z = append(z[:2], z[4:]...)
fmt.Println(z)   //will print Answer [9 8 5 3 2 1 0]

If you know the group id of X, you can use this command to redownload all of X and it's dependencies

mvn clean dependency:purge-local-repository -DresolutionFuzziness=org.id.of.x

It does the same thing as the other answers that propose using dependency:purge-local-repository, but it only deletes and redownloads everything related to X.

My solution is:

-vm

I had the same issue as above and I am using PostgreSQL 10.5. I tried everything as above but nothing seems to be working.

Then I closed the pgadmin and opened a session for the PSQL terminal. Logged into the PSQL and connected to the database and schema respectively :

\c <DATABASE_NAME>;
set search_path to <SCHEMA_NAME>;

Then, restarted the pgadmin console and then I was able to work without issue in the query-tool of the pagadmin.

please Find below one it helps me a lot to set data function

$('#datepicker').datepicker({dateFormat: 'yy-mm-dd'}).datepicker('setDate', '2010-07-25');

How about

a["abc"] = [1, 2]

This will result in:

>>> a
{'abc': [1, 2]}

Is that what you were looking for?

That's what ln is documented to do when the target already exists and is a directory. If you want /etc/nginx to be a symlink rather than contain a symlink, you had better not create it as a directory first!

@RequestParam annotation used for accessing the query parameter values from the request. Look at the following request URL:

http://localhost:8080/springmvc/hello/101?param1=10&param2=20

In the above URL request, the values for param1 and param2 can be accessed as below:

public String getDetails(
    @RequestParam(value="param1", required=true) String param1,
        @RequestParam(value="param2", required=false) String param2){
...
}

The following are the list of parameters supported by the @RequestParam annotation:

• defaultValue – This is the default value as a fallback mechanism if request is not having the value or it is empty.
• name – Name of the parameter to bind
• required – Whether the parameter is mandatory or not. If it is true, failing to send that parameter will fail.
• value – This is an alias for the name attribute

@PathVariable

@PathVariable identifies the pattern that is used in the URI for the incoming request. Let’s look at the below request URL:

http://localhost:8080/springmvc/hello/101?param1=10&param2=20

The above URL request can be written in your Spring MVC as below:

@RequestMapping("/hello/{id}")    public String getDetails(@PathVariable(value="id") String id,
    @RequestParam(value="param1", required=true) String param1,
    @RequestParam(value="param2", required=false) String param2){
.......
}

The @PathVariable annotation has only one attribute value for binding the request URI template. It is allowed to use the multiple @PathVariable annotation in the single method. But, ensure that no more than one method has the same pattern.

Also there is one more interesting annotation: @MatrixVariable

http://localhost:8080/spring_3_2/matrixvars/stocks;BT.A=276.70,+10.40,+3.91;AZN=236.00,+103.00,+3.29;SBRY=375.50,+7.60,+2.07

And the Controller method for it

 @RequestMapping(value = "/{stocks}", method = RequestMethod.GET)
  public String showPortfolioValues(@MatrixVariable Map<String, List<String>> matrixVars, Model model) {

    logger.info("Storing {} Values which are: {}", new Object[] { matrixVars.size(), matrixVars });

    List<List<String>> outlist = map2List(matrixVars);
    model.addAttribute("stocks", outlist);

    return "stocks";
  }

But you must enable:

<mvc:annotation-driven enableMatrixVariables="true" >

It seems that the original test case is wrong.

I can confirm that the selector #my_parent_element * works with unbind().

Let's take the following html as an example:

<div id="#my_parent_element">
  <div class="div1">
    <div class="div2">hello</div>
    <div class="div3">my</div>
  </div>
  <div class="div4">name</div>
  <div class="div5">
    <div class="div6">is</div>
    <div class="div7">
      <div class="div8">marco</div>
      <div class="div9">(try and click on any word)!</div>
    </div>
  </div>
</div>
<button class="unbind">Now, click me and try again</button>

And the jquery bit:

$('.div1,.div2,.div3,.div4,.div5,.div6,.div7,.div8,.div9').click(function() {
  alert('hi!');
})
$('button.unbind').click(function() {
  $('#my_parent_element *').unbind('click');
})

You can try it here: http://jsfiddle.net/fLvwbazk/7/

With personal experience of using the following code within a Stored Procedure which Hashed a SP Variable I can confirm, although undocumented, this combination works 100% as per my example:

@var=SUBSTRING(master.dbo.fn_varbintohexstr(HashBytes('SHA2_512', @SPvar)), 3, 128)

RaisedButton( child: Row( mainAxisAlignment: MainAxisAlignment.center, children: [Text('Submit')], ) ) It works for me.

Honestly, I like the other answers. Easy and no need to get into JS. But I noticed that you were asking about jQuery. So for the sake of completeness, in jQuery if you return false with the .click() handler, it will negate the default action of the widget.

See here for an example (and more goodies, too). Here's the documentation, too.

in a nutshell, with your sample code, do this:

<script type="text/javascript">
    $('button[type!=submit]').click(function(){
        // code to cancel changes
        return false;
    });
</script>

<a href="index.html"><button>Cancel changes</button></a>
<button type="submit">Submit</button>

As an added benefit, with this, you can get rid of the anchor tag and just use the button.

Here is an easy way to get the file name from a path:

echo "$PATH" | rev | cut -d"/" -f1 | rev

To remove the extension you can use, assuming the file name has only ONE dot (the extension dot):

cut -d"." -f1

Check out this link for more details.

To find files which are created in last one hour in current directory, you can use -amin

find . -amin -60 -type f

This will find files which are created with in last 1 hour.

I don't know why

cfg_name_unique NOT LIKE '%categories%' 

still returns those two values, but maybe exclude them explicit:

SELECT *
    FROM developer_configurations_cms

    WHERE developer_configurations_cms.cat_id = '1'
    AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%'
    AND developer_configurations_cms.cfg_name_unique NOT LIKE '%categories%'
    AND developer_configurations_cms.cfg_name_unique NOT IN ('categories_posts', 'categories_news')

shell_exec returns all of the output stream as a string. exec returns the last line of the output by default, but can provide all output as an array specifed as the second parameter.

See

Yegor256's answer worked for me, but I thought I would just add some comments to help out those who are not so good at mounting drives(like me!):

Amazon gives you a choice of what you want to name the volume when you attach it. You have use a name in the range from /dev/sda - /dev/sdp The newer versions of Ubuntu will then rename what you put in there to /dev/xvd(x) or something to that effect.

So for me, I chose /dev/sdp as name the mount name in AWS, then I logged into the server, and discovered that Ubuntu had renamed my volume to /dev/xvdp1). I then had to mount the drive - for me I had to do it like this:

mount -t ext4 xvdp1 /mnt/tmp

After jumping through all those hoops I could access my files at /mnt/tmp

Updating this (9 years after it was asked) as the answer I was looking for wasn't mentioned:

Firefox also has presets for throttling connection speeds. Find them in the Network Monitor tab of the developer tools. Default is 'No throttling'.

Slowest is GPRS (Download speed: 50 Kbps, Upload speed: 20 Kbps, Minimum latency (ms): 500), ranging through 'good' and 'regular' 2G, 3G and 4G to DSL and WiFi (Download speed: 30Mbps, Upload speed: 15Mbps, Minimum latency (ms): 2).

More in the Dev Tools docs.

If you only want to animate the height of a view (from say 0 to a certain number) you could implement your own animation:

final View v = getTheViewToAnimateHere();
Animation anim=new Animation(){
    protected void applyTransformation(float interpolatedTime, Transformation t) {
        super.applyTransformation(interpolatedTime, t);
        // Do relevant calculations here using the interpolatedTime that runs from 0 to 1
        v.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, (int)(30*interpolatedTime)));
    }};
anim.setDuration(500);
v.startAnimation(anim);

you can also use andSelf() method to get wrapper DOM contain then find() can be work around as your idea

$(function() {_x000D_
  $('.slide-link').andSelf().find('[data-slide="0"]').addClass('active');_x000D_
})

.active {_x000D_
  background: green;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<a class="slide-link" href="#" data-slide="0">1</a>_x000D_
<a class="slide-link" href="#" data-slide="1">2</a>_x000D_
<a class="slide-link" href="#" data-slide="2">3</a>

I made a node module to automate this task: mddir

Usage

node mddir "../relative/path/"

To install: npm install mddir -g

To generate markdown for current directory: mddir

To generate for any absolute path: mddir /absolute/path

To generate for a relative path: mddir ~/Documents/whatever.

The md file gets generated in your working directory.

Currently ignores node_modules, and .git folders.

Troubleshooting

If you receive the error 'node\r: No such file or directory', the issue is that your operating system uses different line endings and mddir can't parse them without you explicitly setting the line ending style to Unix. This usually affects Windows, but also some versions of Linux. Setting line endings to Unix style has to be performed within the mddir npm global bin folder.

Line endings fix

Get npm bin folder path with:

npm config get prefix

Cd into that folder

brew install dos2unix

dos2unix lib/node_modules/mddir/src/mddir.js

This converts line endings to Unix instead of Dos

Then run as normal with: node mddir "../relative/path/".

I know this is quite late to answer this question but I resolved this problem by myself and thought worth sharing it with everyone.`

public void replaceFragment(BaseFragment fragment) {
    FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
    final FragmentManager fManager = getSupportFragmentManager();
    BaseFragment fragm = (BaseFragment) fManager.findFragmentByTag(fragment.getFragmentTag());
    transaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left, R.anim.enter_from_left, R.anim.exit_to_right);

    if (fragm == null) {  //here fragment is not available in the stack
        transaction.replace(R.id.container, fragment, fragment.getFragmentTag());
        transaction.addToBackStack(fragment.getFragmentTag());
    } else { 
        //fragment was found in the stack , now we can reuse the fragment
        // please do not add in back stack else it will add transaction in back stack
        transaction.replace(R.id.container, fragm, fragm.getFragmentTag()); 
    }
    transaction.commit();
}

And in the onBackPressed()

 @Override
public void onBackPressed() {
    if(getSupportFragmentManager().getBackStackEntryCount()>1){
        super.onBackPressed();
    }else{
        finish();
    }
}

Marco's answer above is correct, but just to expand on the question of "under what context"...

frame - this is the property you most often use for normal iPhone applications. most controls will be laid out relative to the "containing" control so the frame.origin will directly correspond to where the control needs to display, and frame.size will determine how big to make the control.

center - this is the property you will likely focus on for sprite based games and animations where movement or scaling may occur. By default animation and rotation will be based on the center of the UIView. It rarely makes sense to try and manage such objects by the frame property.

bounds - this property is not a positioning property, but defines the drawable area of the UIView "relative" to the frame. By default this property is usually (0, 0, width, height). Changing this property will allow you to draw outside of the frame or restrict drawing to a smaller area within the frame. A good discussion of this can be found at the link below. It is uncommon for this property to be manipulated unless there is specific need to adjust the drawing region. The only exception is that most programs will use the [[UIScreen mainScreen] bounds] on startup to determine the visible area for the application and setup their initial UIView's frame accordingly.

Why is there an frame rectangle and an bounds rectangle in an UIView?

Hopefully this helps clarify the circumstances where each property might get used.

If you have a UITabController with Screens with Embeded Navigation Controllers, you have to set the UITabController Presentation to FullScreen as shown in pic below

To get the behavior you want you need to wait for the process to finish before you exit Main(). To be able to tell when your process is done you need to return a Task instead of a void from your function, you should never return void from a async function unless you are working with events.

A re-written version of your program that works correctly would be

class Program {     static void Main(string[] args)     {         Debug.WriteLine("Calling DoDownload");         var downloadTask = DoDownloadAsync();         Debug.WriteLine("DoDownload done");         downloadTask.Wait(); //Waits for the background task to complete before finishing.      }      private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } } 

Because you can not await in Main() I had to do the Wait() function instead. If this was a application that had a SynchronizationContext I would do await downloadTask; instead and make the function this was being called from async.

Another option I like, which can be generalized once I start seeing the code not conform to DRY, is to use one controller that redirects to another controller.

public ActionResult ClientIdSearch(int cid)
{
  var action = String.Format("Details/{0}", cid);

  return RedirectToAction(action, "Accounts");
}

I find this allows me to apply my logic in one location and re-use it without have to sprinkle JavaScript in the views to handle this. And, as I mentioned I can then refactor for re-use as I see this getting abused.

It would match any element p that's immediately adjacent to an element 'p'. See: http://www.w3.org/TR/CSS2/selector.html

A char doesn't have any methods - it's a Java primitive. You're looking for the Character wrapper class.

The usage would be:

if(Character.isLetter(ch)) { //... }

I tried using a CLR function and it was more than twice as fast as BCP. Here's my code.

Original Method:

SET @bcpCommand = 'bcp "SELECT blobcolumn FROM blobtable WHERE ID = ' + CAST(@FileID AS VARCHAR(20)) + '" queryout "' + @FileName + '" -T -c'
EXEC master..xp_cmdshell @bcpCommand

CLR Method:

declare @file varbinary(max) = (select blobcolumn from blobtable WHERE ID = @fileid)
declare @filepath nvarchar(4000) = N'c:\temp\' + @FileName
SELECT Master.dbo.WriteToFile(@file, @filepath, 0)

C# Code for the CLR function

using System;
using System.Data;
using System.Data.SqlTypes;
using System.IO;
using Microsoft.SqlServer.Server;

{
    public class Functions

      public static SqlString WriteToFile(SqlBytes binary, SqlString path, SqlBoolean append)
      {        
        try

                {
                    fs.WriteByte(byteArr[i]);
                };
            }
            return "SUCCESS";
          }
          else
             "NULL INPUT";
        }
        catch (Exception ex)
        {          
          return ex.Message;
        }
      }
    }
}

To elaborate on the other answers provided, this is my solution (placed in an Activity):

@Override
public void onBackPressed(){
    FragmentManager fm = getFragmentManager();
    if (fm.getBackStackEntryCount() > 0) {
        Log.i("MainActivity", "popping backstack");
        fm.popBackStack();
    } else {
        Log.i("MainActivity", "nothing on backstack, calling super");
        super.onBackPressed();  
    }
}

It's simply “No such directory entry”. Since directory entries can be directories or files (or symlinks, or sockets, or pipes, or devices), the name ENOFILE would have been too narrow in its meaning.

The fundamental difference in most programming languages is that unless the unexpected happens a for loop will always repeat n times or until a break statement, (which may be conditional), is met then finish with a while loop it may repeat 0 times, 1, more or even forever, depending on a given condition which must be true at the start of each loop for it to execute and always false on exiting the loop, (for completeness a do ... while loop, (or repeat until), for languages that have it, always executes at least once and does not guarantee the condition on the first execution).

It is worth noting that in Python a for or while statement can have break, continue and else statements where:

• break - terminates the loop
• continue - moves on to the next time around the loop without executing following code this time around
• else - is executed if the loop completed without any break statements being executed.

N.B. In the now unsupported Python 2 range produced a list of integers but you could use xrange to use an iterator. In Python 3 range returns an iterator.

So the answer to your question is 'it all depends on what you are trying to do'!

volatile is a field modifier, while synchronized modifies code blocks and methods. So we can specify three variations of a simple accessor using those two keywords:

    int i1;
    int geti1() {return i1;}

    volatile int i2;
    int geti2() {return i2;}

    int i3;
    synchronized int geti3() {return i3;}

geti1() accesses the value currently stored in i1 in the current thread. Threads can have local copies of variables, and the data does not have to be the same as the data held in other threads.In particular, another thread may have updated i1 in it's thread, but the value in the current thread could be different from that updated value. In fact Java has the idea of a "main" memory, and this is the memory that holds the current "correct" value for variables. Threads can have their own copy of data for variables, and the thread copy can be different from the "main" memory. So in fact, it is possible for the "main" memory to have a value of 1 for i1, for thread1 to have a value of 2 for i1 and for thread2 to have a value of 3 for i1 if thread1 and thread2 have both updated i1 but those updated value has not yet been propagated to "main" memory or other threads.

On the other hand, geti2() effectively accesses the value of i2 from "main" memory. A volatile variable is not allowed to have a local copy of a variable that is different from the value currently held in "main" memory. Effectively, a variable declared volatile must have it's data synchronized across all threads, so that whenever you access or update the variable in any thread, all other threads immediately see the same value. Generally volatile variables have a higher access and update overhead than "plain" variables. Generally threads are allowed to have their own copy of data is for better efficiency.

There are two differences between volitile and synchronized.

Firstly synchronized obtains and releases locks on monitors which can force only one thread at a time to execute a code block. That's the fairly well known aspect to synchronized. But synchronized also synchronizes memory. In fact synchronized synchronizes the whole of thread memory with "main" memory. So executing geti3() does the following:

1. The thread acquires the lock on the monitor for object this .
2. The thread memory flushes all its variables, i.e. it has all of its variables effectively read from "main" memory .
3. The code block is executed (in this case setting the return value to the current value of i3, which may have just been reset from "main" memory).
4. (Any changes to variables would normally now be written out to "main" memory, but for geti3() we have no changes.)
5. The thread releases the lock on the monitor for object this.

So where volatile only synchronizes the value of one variable between thread memory and "main" memory, synchronized synchronizes the value of all variables between thread memory and "main" memory, and locks and releases a monitor to boot. Clearly synchronized is likely to have more overhead than volatile.

Somewhere in your initialisation put this code.

Array.prototype.contains = function contains(obj) {
    for (var i = 0; i < this.length; i++) {
        if (this[i] === obj) {
            return true;
        }
    }
    return false;
};

Then, you can use it this way:

<li ng-class="{approved: selectedForApproval.contains(jobSet)}"></li>

You need to use the val() function to get the textbox value. text does not exist as a property only as a function and even then its not the correct function to use in this situation.

var from = $("input#fromAddress").val()

val() is the standard function for getting the value of an input.

I was having almost the same problem as this but slightly different on Server 2012 R2. I have a powershell script in Task Scheduler that copies 3 files from one location to another. If I run the script manually from powershell, it works like a charm. But when run from Task Scheduler, it only copies the first 2 small files, then hang on the 3rd (large file). And I was also getting a result of "The operator or administrator has refused the request". And I have done almost everything in this forum.

Here is the scenario and how I fixed it for me. May not work for others, but just in case it will:

Scenario: 1. Powershell script in Task Scheduler 2. Ran using a domain account which is a local admin on the server 3. Selected 'Run whether user is logged on or not" 4. Run with highest priviledges

Fix: 1. I had to login to the server using the domain account so that it created a local profile in C:\Users. 2. Checked and made user that the user has access to all the drives I referred to on my script

I believe #1 is the main fix for me. I hope this works for others out there.

What is Angular CLI Budgets? Budgets is one of the less known features of the Angular CLI. It’s a rather small but a very neat feature!

As applications grow in functionality, they also grow in size. Budgets is a feature in the Angular CLI which allows you to set budget thresholds in your configuration to ensure parts of your application stay within boundaries which you set — Official Documentation

Or in other words, we can describe our Angular application as a set of compiled JavaScript files called bundles which are produced by the build process. Angular budgets allows us to configure expected sizes of these bundles. More so, we can configure thresholds for conditions when we want to receive a warning or even fail build with an error if the bundle size gets too out of control!

How To Define A Budget? Angular budgets are defined in the angular.json file. Budgets are defined per project which makes sense because every app in a workspace has different needs.

Thinking pragmatically, it only makes sense to define budgets for the production builds. Prod build creates bundles with “true size” after applying all optimizations like tree-shaking and code minimization.

Oops, a build error! The maximum bundle size was exceeded. This is a great signal that tells us that something went wrong…

1. We might have experimented in our feature and didn’t clean up properly
2. Our tooling can go wrong and perform a bad auto-import, or we pick bad item from the suggested list of imports
3. We might import stuff from lazy modules in inappropriate locations
4. Our new feature is just really big and doesn’t fit into existing budgets

First Approach: Are your files gzipped?

Generally speaking, gzipped file has only about 20% the size of the original file, which can drastically decrease the initial load time of your app. To check if you have gzipped your files, just open the network tab of developer console. In the “Response Headers”, if you should see “Content-Encoding: gzip”, you are good to go.

How to gzip? If you host your Angular app in most of the cloud platforms or CDN, you should not worry about this issue as they probably have handled this for you. However, if you have your own server (such as NodeJS + expressJS) serving your Angular app, definitely check if the files are gzipped. The following is an example to gzip your static assets in a NodeJS + expressJS app. You can hardly imagine this dead simple middleware “compression” would reduce your bundle size from 2.21MB to 495.13KB.

const compression = require('compression')
const express = require('express')
const app = express()
app.use(compression())

Second Approach:: Analyze your Angular bundle

If your bundle size does get too big you may want to analyze your bundle because you may have used an inappropriate large-sized third party package or you forgot to remove some package if you are not using it anymore. Webpack has an amazing feature to give us a visual idea of the composition of a webpack bundle.

It’s super easy to get this graph.

1. npm install -g webpack-bundle-analyzer
2. In your Angular app, run ng build --stats-json (don’t use flag --prod). By enabling --stats-json you will get an additional file stats.json
3. Finally, run webpack-bundle-analyzer ./dist/stats.json and your browser will pop up the page at localhost:8888. Have fun with it.

the rdl file content:

<Visibility><Hidden>=Parameters!casetype.Value=300</Hidden></Visibility>

so the text box will hidden, if your expression is true.

Add width:100px, margin:50%. Now the left side of the button is set to the center.
Finally add half of the width of the button in our case 50px.
The middle of the button is in the center.

<input type='submit' style='width:100px;margin:0 50%;position:relative;left:-50px;'>

Try this:

i = 5
ii = 10
if i == 5 and ii == 10:
      print "i is 5 and ii is 10"

Edit: Oh, and you dont need that semicolon on the last line (edit to remove it from my code).

You Can Show Facebook Share/Like Count Like This: ( Tested and Verified)

$url = http://www.yourdomainname.com // You can use inner pages

$rest_url = "http://api.facebook.com/restserver.php?format=json&method=links.getStats&urls=".urlencode($url);

$json = json_decode(file_get_contents($rest_url),true);


echo Facebook Shares = '.$json[0][share_count];

echo Facebook Likes = '.$json[0][like_count];

echo Facebook Comments = '.$json[0][comment_count];

Simple prevent the default behavior of click, dblclick or touchend events will disable the zoom functionality.

If you have already a callback on one of this events just call a event.preventDefault().

I was having similar problem and

var dataObj = JSON.parse(data);

console.log(dataObj[0].category); //will return Damskie
console.log(dataObj[1].category); //will return Meskie

This solved my problem. Thanks Selvakumar Arumugam

Java only knows about the platform it is currently running on, so it can only give you a platform-dependent output on that platform (using bw.newLine()) . The fact that you open it on a windows system means that you either have to convert the file before using it (using something you have written, or using a program like unix2dos), or you have to output the file with windows format carriage returns in it originally in your Java program. So if you know the file will always be opened on a windows machine, you will have to output

bw.write(rs.getString(1)==null? "":rs.getString(1));
bw.write("\r\n");

It's worth noting that you aren't going to be able to output a file that will look correct on both platforms if it is just plain text you are using, you may want to consider using html if it is an email, or xml if it is data. Alternatively, you may need some kind of client that reads the data and then formats it for the platform that the viewer is using.

Here are two methods to get more than 1 column in a scalar subquery (or inline subquery) and querying the lookup table only once. This is a bit convoluted but can be the very efficient in some special cases.

1. You can use concatenation to get several columns at once:

   SELECT x, 
          regexp_substr(yz, '[^^]+', 1, 1) y,
          regexp_substr(yz, '[^^]+', 1, 2) z
     FROM (SELECT a.x,
                  (SELECT b.y || '^' || b.z yz
                     FROM b
                    WHERE b.v = a.v)
                     yz
             FROM a)
   

   You would need to make sure that no column in the list contain the separator character.

2. You could also use SQL objects:

   CREATE OR REPLACE TYPE b_obj AS OBJECT (y number, z number);
   
   SELECT x, 
          v.yz.y y,
          v.yz.z z
     FROM (SELECT a.x,
                  (SELECT b_obj(y, z) yz
                     FROM b
                    WHERE b.v = a.v)
                     yz
             FROM a) v

I found that I missed Java builder in my .project

If something is missing in your buildSpec, close Eclipse, make sure everything is in place and start Eclipse again

        <buildSpec>
            <buildCommand>

In my case I had Java 7 and 8 (both x64) installed and I want to redirect to java 7 but everything is set to use Java 8. Java uses the PATH environment variable:

C:\ProgramData\Oracle\Java\javapath

as the first option to look for its folder runtime (is a hidden folder). This path contains 3 symlinks that can't be edited.

In my pc, the PATH environment variable looks like this:

C:\ProgramData\Oracle\Java\javapath;C:\Windows\System32;C:\Program Files\Java\jdk1.7.0_21\bin;

In my case, It should look like this:

C:\Windows\System32;C:\Program Files\Java\jdk1.7.0_21\bin;

I had to cut and paste the symlinks to somewhere else so java can't find them, and I can restore them later.

After setting the JAVA_HOME and JRE_HOME environment variables to the desired java folders' runtimes (in my case it is Java 7), the command java -version should show your desired java runtime. I remark there's no need to mess with the registry.

Tested on Win7 x64.

Answer to use "/I" is working but with little trick - in target you must end with character \ to tell xcopy that target is directory and not file!

Example:

xcopy "$(TargetDir)$(TargetName).dll" "$(SolutionDir)_DropFolder" /F /R /Y /I

does not work and return code 2, but this one:

xcopy "$(TargetDir)$(TargetName).dll" "$(SolutionDir)_DropFolder\" /F /R /Y /I

Command line arguments used in my sample:

/F - Displays full source & target file names

/R - This will overwrite read-only files

/Y - Suppresses prompting to overwrite an existing file(s)

/I - Assumes that destination is directory (but must ends with \)

I know this is an old thread but PARTITION is the equiv of GROUP BY not ORDER BY. ORDER BY in this function is . . . ORDER BY. It's just a way to create uniqueness out of redundancy by adding a sequence number. Or you may eliminate the other redundant records by the WHERE clause when referencing the aliased column for the function. However, DISTINCT in the SELECT statement would probably accomplish the same thing in that regard.

Just putting it in src/main/resources will bundle it inside the artifact. E.g. if your artifact is a JAR, you will have the log4j.properties file inside it, losing its initial point of making logging configurable.

I usually put it in src/main/resources, and set it to be output to target like so:

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <targetPath>${project.build.directory}</targetPath>
            <includes>
                <include>log4j.properties</include>
            </includes>
        </resource>
    </resources>
</build>

Additionally, in order for log4j to actually see it, you have to add the output directory to the class path. If your artifact is an executable JAR, you probably used the maven-assembly-plugin to create it. Inside that plugin, you can add the current folder of the JAR to the class path by adding a Class-Path manifest entry like so:

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <mainClass>com.your-package.Main</mainClass>
            </manifest>
            <manifestEntries>
                <Class-Path>.</Class-Path>
            </manifestEntries>
        </archive>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
    <executions>
        <execution>
            <id>make-assembly</id> <!-- this is used for inheritance merges -->
            <phase>package</phase> <!-- bind to the packaging phase -->
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Now the log4j.properties file will be right next to your JAR file, independently configurable.

To run your application directly from Eclipse, add the resources directory to your classpath in your run configuration: Run->Run Configurations...->Java Application->New select the Classpath tab, select Advanced and browse to your src/resources directory.

The behaviour is not really that strange. Looking into the implementation of the classes, it is caused by:

• Charset.defaultCharset() is not caching the determined character set in Java 5.
• Setting the system property "file.encoding" and invoking Charset.defaultCharset() again causes a second evaluation of the system property, no character set with the name "Latin-1" is found, so Charset.defaultCharset() defaults to "UTF-8".
• The OutputStreamWriter is however caching the default character set and is probably used already during VM initialization, so that its default character set diverts from Charset.defaultCharset() if the system property "file.encoding" has been changed at runtime.

As already pointed out, it is not documented how the VM must behave in such a situation. The Charset.defaultCharset() API documentation is not very precise on how the default character set is determined, only mentioning that it is usually done on VM startup, based on factors like the OS default character set or default locale.

I am quite benefited with http://stackoverflow.com. I was wandering from hours for automatic login and submit from vb application to another web site. Due to help of this site I am able to complete my task

I have to login following web php page.

<HTML>

<div align="center"><img src="banner.png" height="80px" /></div>
<script type="text/javascript">
$(document).ready(function(){
            $("#login").validate();
            $("#login_container").css({'position': 'absolute', 
                'top' : (($(window).height()/2) - $("#login_container").height()/2)+'px'});
            $("#login_container").css({'left' : (($(window).width()/2) - $("#login_container").width()/2)+'px'});
        });

Public Class Form1


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click


        WebBrowser1.Navigate("http://xyz.com")



    End Sub

    Private Sub WebBrowser1_DocumentCompleted(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
        WebBrowser1.Document.GetElementById("name").SetAttribute("Value", "bharatlal")
        WebBrowser1.Document.GetElementById("password").SetAttribute("Value", "mahato")
        WebBrowser1.Document.GetElementById("subimt").Focus()
        WebBrowser1.Document.GetElementById("subimt").InvokeMember("click")
    End Sub
End Class

Perfectly worked for me

jQuery('#datetimepicker1').datetimepicker({
    use24hours: true,   
    format: "YYYY-MM-DD HH:mm ",

    });

mvn clean package -DpropEnv=PROD

Then using like this in POM.xml

<properties>
    <myproperty>${propEnv}</myproperty>
</properties>

in which element is currently the class '.bar' ? Here is another solution but it's up to you.

var reg = /Image/g, // regexp for an image element
query = document.querySelector('.bar'); // returns [object HTMLImageElement]
query += this.toString(); // turns object into a string

if (query.match(reg)) { // checks if it matches
  alert('the class .bar is attached to the following Element:\n' + query);
}

jsfiddle demo

Of course this is only a lookup for 1 simple element <img>(/Image/g) but you can put all in an array like <li> is /LI/g, <ul> = /UL/g etc.

JSON is essentially a String in PHP or JAVA context. That means string which is valid JSON can be returned in response. Following should work.

  @RequestMapping(value="/user/addUser", method=RequestMethod.POST)
  @ResponseBody
  public String addUser(@ModelAttribute("user") User user) {

    if (user != null) {
      logger.info("Inside addIssuer, adding: " + user.toString());
    } else {
      logger.info("Inside addIssuer...");
    }
    users.put(user.getUsername(), user);
    return "{\"success\":1}";
  }

This is okay for simple string response. But for complex JSON response you should use wrapper class as described by Shaun.

The pageContext is an implicit object available in JSPs. The EL documentation says

The context for the JSP page. Provides access to various objects including:
servletContext: ...
session: ...
request: ...
response: ...

Thus this expression will get the current HttpServletRequest object and get the context path for the current request and append /JSPAddress.jsp to it to create a link (that will work even if the context-path this resource is accessed at changes).

The primary purpose of this expression would be to keep your links 'relative' to the application context and insulate them from changes to the application path.

For example, if your JSP (named thisJSP.jsp) is accessed at http://myhost.com/myWebApp/thisJSP.jsp, thecontext path will be myWebApp. Thus, the link href generated will be /myWebApp/JSPAddress.jsp.

If someday, you decide to deploy the JSP on another server with the context-path of corpWebApp, the href generated for the link will automatically change to /corpWebApp/JSPAddress.jsp without any work on your part.

For those who are looking to sort whether or not there are optgroup :

/**
 * Sorting options 
 * and optgroups
 * 
 * @param selElem select element
 * @param optionBeforeGroup ?bool if null ignores, if true option appear before group else option appear after group
 */
function sortSelect(selElem, optionBeforeGroup = null) {
    let initialValue = selElem.tagName === "SELECT" ? selElem.value : null; 
    let allChildrens = Array.prototype.slice.call(selElem.childNodes);
    let childrens = [];

    for (let i = 0; i < allChildrens.length; i++) {
        if (allChildrens[i].parentNode === selElem && ["OPTGROUP", "OPTION"].includes(allChildrens[i].tagName||"")) {
            if (allChildrens[i].tagName == "OPTGROUP") {
                sortSelect(allChildrens[i]);
            }
            childrens.push(allChildrens[i]);
        }
    }

    childrens.sort(function(a, b){
        let x = a.tagName == "OPTGROUP" ? a.getAttribute("label") : a.innerHTML;
        let y = b.tagName == "OPTGROUP" ? b.getAttribute("label") : b.innerHTML;
        x = typeof x === "undefined" || x === null ? "" : (x+"");
        y = typeof y === "undefined" || y === null ? "" : (y+"");

In General...

The method exposed by sykora is the best option in this case. But sometimes is not the easiest and it's not a general method. For a general method use git cherry-pick:

To achieve what OP wants, its a 2-step process:

Step 1 - Note which commits from master you want on a newbranch

Execute

git checkout master
git log

Note the hashes of (say 3) commits you want on newbranch. Here I shall use:
C commit: 9aa1233
D commit: 453ac3d
E commit: 612ecb3

Note: You can use the first seven characters or the whole commit hash

Step 2 - Put them on the newbranch

git checkout newbranch
git cherry-pick 612ecb3
git cherry-pick 453ac3d
git cherry-pick 9aa1233

OR (on Git 1.7.2+, use ranges)

git checkout newbranch
git cherry-pick 612ecb3~1..9aa1233

git cherry-pick applies those three commits to newbranch.

Put empty value if the value does not exist or null.

value={ this.state.value || "" }

Let's just say you have 3 buttons:

<input type="button" disabled="disabled" value="hello world">
<input type="button" disabled value="hello world">
<input type="button" value="hello world">

To style the disabled button you can use the following css:

input[type="button"]:disabled{
    color:#000;
}

This will only affect the button which is disabled.

To stop the color changing when hovering you can use this too:

input[type="button"]:disabled:hover{
    color:#000;
}

You can also avoid this by using a css-reset.

Here is an example JSFiddle - http://jsfiddle.net/6yL6t/

And the code:

function hashCode(str) {
    var hash = 0, i, chr, len;
    if (str.length == 0) return hash;
    for (i = 0, len = str.length; i < len; i++) {
        chr   = str.charCodeAt(i);
        hash  = ((hash << 5) - hash) + chr;
        hash |= 0; // Convert to 32bit integer
    }
    return hash;
}

var onceHashes = {};

function once(func) {
    var unique = hashCode(func.toString().match(/function[^{]+\{([\s\S]*)\}$/)[1]);

    if (!onceHashes[unique]) {
        onceHashes[unique] = true;
        func();
    }
}

You could do:

for (var i=0; i<10; i++) {
    once(function() {
        alert(i);
    });
}

And it will run only once :)

You can also use the command line, Change directory where your folder is located then type the following :

     git init
     git add <folder1> <folder2> <etc.>
     git commit -m "Your message about the commit"
     git remote add origin https://github.com/yourUsername/yourRepository.git
     git push -u origin master
     git push origin master  

ulimit -c unlimited

is a system variable, wich will allow to create a core dump after your application crashes. In this case an unlimited amount. Look for a file called core in the very same directory. Make sure you compiled your code with debugging informations enabled!

Found the answer. What I did was was first

sudo apt-get install aptitude
sudo aptitude install libglib2.0-0
sudo aptitude install gcc-4.7 make linux-headers-`uname -r` -y

and tried it but it didn't work so I continued and did

sudo apt-get install build-essential
sudo apt-get install gcc-4.7 linux-headers-`uname -r`

after doing these two steps and trying again, it worked.

It sounds less like a Java synchronization issue and more like a database locking problem.

I don't know if adding a version to all your persistent classes will sort it out, but that's one way that Hibernate can provide exclusive access to rows in a table.

Could be that isolation level needs to be higher. If you allow "dirty reads", maybe you need to bump up to serializable.

Run all Collection in a folder in parallel:

'use strict';

global.Promise = require('bluebird');
const path = require('path');
const newman =  Promise.promisifyAll(require('newman'));
const fs = Promise.promisifyAll(require('fs'));
const environment = 'postman_environment.json';
const FOLDER = path.join(__dirname, 'Collections_Folder');


let files = fs.readdirSync(FOLDER);
files = files.map(file=> path.join(FOLDER, file))
console.log(files);

Promise.map(files, file => {

    return newman.runAsync({
    collection: file, // your collection
    environment: path.join(__dirname, environment), //your env
    reporters: ['cli']
    });

}, {
   concurrency: 2
});

Since tr:not(:first-child) is not supported by IE 6, 7, 8. You can use the help of jQuery. You may find it here

Cast the dtype of the col to str and you can perform vectorised slicing calling str:

In [29]:
df['new_col'] = df['First'].astype(str).str[0]
df

Out[29]:
   First  Second new_col
0    123     234       1
1     22    4353       2
2     32     355       3
3    453     453       4
4     45     345       4
5    453     453       4
6     56      56       5

if you need to you can cast the dtype back again calling astype(int) on the column

LDAP stands for Lightweight Directory Access Protocol. As the name suggests, it is a lightweight protocol for accessing directory services, specifically X.500-based directory services. LDAP runs over TCP/IP or other connection oriented transfer services. The nitty-gritty details of LDAP are defined in RFC2251 "The Lightweight Directory Access Protocol (v3)" and other documents comprising the technical specification RFC3377. This section gives an overview of LDAP from a user's perspective.

What kind of information can be stored in the directory? The LDAP information model is based on entries. An entry is a collection of attributes that has a globally-unique Distinguished Name (DN). The DN is used to refer to the entry unambiguously. Each of the entry's attributes has a type and one or more values. The types are typically mnemonic strings, like cn for common name, or mail for email address. The syntax of values depend on the attribute type. For example, a cn attribute might contain the value Babs Jensen. A mail attribute might contain the value [email protected]. A jpegPhoto attribute would contain a photograph in the JPEG (binary) format.

How is the information arranged? In LDAP, directory entries are arranged in a hierarchical tree-like structure.

len(each) == max(len(x) for x in myList) or just each == max(myList, key=len)

For Autodidacts:

function BaseClass(toBePrivate){
    var morePrivates;
    this.isNotPrivate = 'I know';
    // add your stuff
}
var o = BaseClass.prototype;
// add your prototype stuff
o.stuff_is_never_private = 'whatever_except_getter_and_setter';


// MiddleClass extends BaseClass
function MiddleClass(toBePrivate){
    BaseClass.call(this);
    // add your stuff
    var morePrivates;
    this.isNotPrivate = 'I know';
}
var o = MiddleClass.prototype = Object.create(BaseClass.prototype);
MiddleClass.prototype.constructor = MiddleClass;
// add your prototype stuff
o.stuff_is_never_private = 'whatever_except_getter_and_setter';



// TopClass extends MiddleClass
function TopClass(toBePrivate){
    MiddleClass.call(this);
    // add your stuff
    var morePrivates;
    this.isNotPrivate = 'I know';
}
var o = TopClass.prototype = Object.create(MiddleClass.prototype);
TopClass.prototype.constructor = TopClass;
// add your prototype stuff
o.stuff_is_never_private = 'whatever_except_getter_and_setter';


// to be continued...

Create "instance" with getter and setter:

function doNotExtendMe(toBePrivate){
    var morePrivates;
    return {
        // add getters, setters and any stuff you want
    }
}

If you want to see what you you have inside an object in your web app, then use the json pipe in a component HTML template, for example:

<li *ngFor="let obj of myArray">{{obj | json}}</li>

Tested and valid using Angular 4.3.2.

The accepted answer offers a solution which requires changing of the underlying data frame. This is not necessary. One can also simply factorise within the aes() call directly or create a vector for that instead.

This is certainly not much different than user Drew Steen's answer, but with the important difference of not changing the original data frame.

level_order <- c('virginica', 'versicolor', 'setosa') #this vector might be useful for other plots/analyses

ggplot(iris, aes(x = factor(Species, level = level_order), y = Petal.Width)) + geom_col()

or

level_order <- factor(iris$Species, level = c('virginica', 'versicolor', 'setosa'))

ggplot(iris, aes(x = level_order, y = Petal.Width)) + geom_col()

or
directly in the aes() call without a pre-created vector:

ggplot(iris, aes(x = factor(Species, level = c('virginica', 'versicolor', 'setosa')), y = Petal.Width)) + geom_col()

As also noted by John Szakmeister and VasiliNovikov, the shortest command to get the full diff from master's perspective on your branch is:

git diff master...

This uses your local copy of master.

To compare a specific file use:

git diff master... filepath

Output example:

Another possible solution: create an object containing the group names and indexes.

var regex = new RegExp("(.*) (.*)");
var regexGroups = { FirstName: 1, LastName: 2 };

Then, use the object keys to reference the groups:

var m = regex.exec("John Smith");
var f = m[regexGroups.FirstName];

This improves the readability/quality of the code using the results of the regex, but not the readability of the regex itself.

Try this...

while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {

It's like this:

$('.tag.clickedTag').click(function (){ 
 // this will catch with two classes
}

$('.tag.clickedTag.otherclass').click(function (){ 
 // this will catch with three classes
}

$('.tag:not(.clickedTag)').click(function (){ 
 // this will catch tag without clickedTag
}

No one has mentioned using negative inset values for legend. Here is an example, where the legend is to the right of the plot, aligned to the top (using keyword "topright").

# Random data to plot:
A <- data.frame(x=rnorm(100, 20, 2), y=rnorm(100, 20, 2))
B <- data.frame(x=rnorm(100, 21, 1), y=rnorm(100, 21, 1))

# Add extra space to right of plot area; change clipping to figure
par(mar=c(5.1, 4.1, 4.1, 8.1), xpd=TRUE)

# Plot both groups
plot(y ~ x, A, ylim=range(c(A$y, B$y)), xlim=range(c(A$x, B$x)), pch=1,
               main="Scatter plot of two groups")
points(y ~ x, B, pch=3)

# Add legend to top right, outside plot region
legend("topright", inset=c(-0.2,0), legend=c("A","B"), pch=c(1,3), title="Group")

The first value of inset=c(-0.2,0) might need adjusting based on the width of the legend.

I am beginning Angular and in my case, the issue was that I hadn't saved the file after adding the 'import' statement.
