So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

Somehow, where you are using Sentry, you're not using its Facade, but the class itself. When you call a class through a Facade you're not really using statics, it's just looks like you are.

Do you have this:

use Cartalyst\Sentry\Sentry; 

In your code?

Ok, but if this line is working for you:

$user = $this->sentry->register(array(     'username' => e($data['username']),     'email' => e($data['email']),      'password' => e($data['password'])     )); 

So you already have it instantiated and you can surely do:

$adminGroup = $this->sentry->findGroupById(5); 

open windows powershell, run as administrater and SetExecution policy as Unrestricted then it will work.

While I cannot reproduce your error (as none of your team mates can either), I have a suggestion, that might help you.

Have you heard of the Byte Order Mark? As it appears on line 1 it is a likely candidate for your troubles. Maybe you changed a setting somewhere that somehow leads to the error. This quote from the Wikipedia article is particularly relevant I think:

BOM use is optional. Its presence interferes with the use of UTF-8 by software that does not expect non-ASCII bytes at the start of a file but that could otherwise handle the text stream.

function LegoComponent() {

  const [lego, setLegos] = React.useState([])

  React.useEffect(() => {
    let isSubscribed = true
    fetchLegos().then( legos=> {
      if (isSubscribed) {
        setLegos(legos)
      }
    })
    return () => isSubscribed = false
  }, []);

  return (
    <ul>
    {legos.map(lego=> <li>{lego}</li>)}
    </ul>
  )
}

In the code above, the fetchLegos function returns a promise. We can “cancel” the promise by having a conditional in the scope of useEffect, preventing the app from setting state after the component has unmounted.

Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.

Problem is probably this.

You tried to paste it using

• CTRL +V

before and it didn't work so you went ahead and pasted it with classic

• Right Click - Paste**.

Sadly whenever you enter CTRL +V on terminal it adds

• a hidden ^?

(at least on my machine it encoded like that).

the character that you only appears after you

• backspace

(go ahead an try it on git bash).

So your link becomes ^?https://...

which is invalid.

Just need to update the width of the th tag.

th {
  width: 100px;
}

new Buffer(number)            // Old
Buffer.alloc(number)          // New

new Buffer(string)            // Old
Buffer.from(string)           // New

new Buffer(string, encoding)  // Old
Buffer.from(string, encoding) // New

new Buffer(...arguments)      // Old
Buffer.from(...arguments)     // New

Note that Buffer.alloc() is also faster on the current Node.js versions than new Buffer(size).fill(0), which is what you would otherwise need to ensure zero-filling.

The culprit was russian account password.

Accidentally set up it (wrong keyboard layout). Everything was working, so didnt bother changing it.

Out of despair changed it now and it worked.

If someone looked up this thread and its not a solution for you - check out comments under the question and steps i described in question, they might be useful to you.

This is for react-native, but login will work for all types.

isTokenExpired = async () => {
    try {
        const LoginTokenValue = await AsyncStorage.getItem('LoginTokenValue');
        if (JSON.parse(LoginTokenValue).RememberMe) {
            const { exp } = JwtDecode(LoginTokenValue);
            if (exp < (new Date().getTime() + 1) / 1000) {
                this.handleSetTimeout();
                return false;
            } else {
                //Navigate inside the application
                return true;
            }
        } else {
            //Navigate to the login page
        }
    } catch (err) {
        console.log('Spalsh -> isTokenExpired -> err', err);
        //Navigate to the login page
        return false;
    }
}

To send an HTTP DELETE with some headers via axios I've done this:

  const deleteUrl = "http//foo.bar.baz";
  const httpReqHeaders = {
    'Authorization': token,
    'Content-Type': 'application/json'
  };
  // check the structure here: https://github.com/axios/axios#request-config
  const axiosConfigObject = {headers: httpReqHeaders}; 

  axios.delete(deleteUrl, axiosConfigObject);

The axios syntax for different HTTP verbs (GET, POST, PUT, DELETE) is tricky because sometimes the 2nd parameter is supposed to be the HTTP body, some other times (when it might not be needed) you just pass the headers as the 2nd parameter.

However let's say you need to send an HTTP POST request without an HTTP body, then you need to pass undefined as the 2nd parameter.

Bare in mind that according to the definition of the configuration object (https://github.com/axios/axios#request-config) you can still pass an HTTP body in the HTTP call via the data field when calling axios.delete, however for the HTTP DELETE verb it will be ignored.

This confusion between the 2nd parameter being sometimes the HTTP body and some other time the whole config object for axios is due to how the HTTP rules have been implemented. Sometimes an HTTP body is not needed for an HTTP call to be considered valid.

1) This worked for me. First, create a new user. Example: User foo with password bar

> mysql> CREATE USER 'foo'@'localhost' IDENTIFIED WITH mysql_native_password BY 'bar';

2) Replace the below code with a username with 'foo'.

> mysql> GRANT ALL PRIVILEGES ON database_name.* TO'foo'@'localhost';

Note: database_name is the database that you want to have privileges, . means all on all

3) Login as user foo

mysql> mysql -u foo -p

Password: bar

4) Make sure your initial connection from Sequelize is set to foo with pw bar.

I downgraded my Java version to 1.8 and its resolved, here is the link to download JDK8

Run the following command after installing JDK8

   flutter doctor --android-licenses

What i do is to take screen width and height and calculate a grid of 100*100 out of it to position and scale things and save it as static variables that can be reused. Works quite good in most cases. Like this:

AppConfig.width = MediaQuery.of(context).size.width;
AppConfig.height = MediaQuery.of(context).size.height;
AppConfig.blockSize = AppConfig.width / 100;
AppConfig.blockSizeVertical = AppConfig.height / 100;

Then i scale everything according to these values, like this:

double elementWidth = AppConfig.blockSize * 10.0;   // 10% of the screen width

or

double fontSize = AppConfig.blockSize * 1.2;

Sometimes the safe area (notch, etc) kills a layout, so you can consider this, too:

AppConfig.safeAreaHorizontal = MediaQuery.of(context).padding.left +
    MediaQuery.of(context).padding.right;

double screenWidthWithoutSafeArea = AppConfig.width - AppConfig.safeAreaHorizontal;

This worked great on some recent projects.

Others have answered so I'll add my 2-cents.

You can either use autoconfiguration (i.e. don't use a @Configuration to create a datasource) or java configuration.

Auto-configuration:

define your datasource type then set the type properties. E.g.

spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.hikari.driver-class-name=org.h2.Driver
spring.datasource.hikari.jdbc-url=jdbc:h2:mem:testdb
spring.datasource.hikari.username=sa
spring.datasource.hikari.password=password
spring.datasource.hikari.max-wait=10000
spring.datasource.hikari.connection-timeout=30000
spring.datasource.hikari.idle-timeout=600000
spring.datasource.hikari.max-lifetime=1800000
spring.datasource.hikari.leak-detection-threshold=600000
spring.datasource.hikari.maximum-pool-size=100
spring.datasource.hikari.pool-name=MyDataSourcePoolName

Java configuration:

Choose a prefix and define your data source

spring.mysystem.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.mysystem.datasource.jdbc- 
url=jdbc:sqlserver://databaseserver.com:18889;Database=MyDatabase;
spring.mysystem.datasource.username=dsUsername
spring.mysystem.datasource.password=dsPassword
spring.mysystem.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.mysystem.datasource.max-wait=10000
spring.mysystem.datasource.connection-timeout=30000
spring.mysystem.datasource.idle-timeout=600000
spring.mysystem.datasource.max-lifetime=1800000
spring.mysystem.datasource.leak-detection-threshold=600000
spring.mysystem.datasource.maximum-pool-size=100
spring.mysystem.datasource.pool-name=MySystemDatasourcePool

Create your datasource bean:

@Bean(name = { "dataSource", "mysystemDataSource" })
@ConfigurationProperties(prefix = "spring.mysystem.datasource")
public DataSource dataSource() {
    return DataSourceBuilder.create().build();
}

You can leave the datasource type out, but then you risk spring guessing what datasource type to use.

    file = open("path/of/file/(optional)/filename.txt", "w") #a=append,w=write,r=read
    any_string = "Hello\nWorld"
    file.write(any_string)
    file.close()

Yep, and if you have tried all the above solutions (what's more likely to happen) and none work for you, it may happen that Guzzle is not installed.

Laravel ships mailing tools, by which is required the Guzzle framework, but it won't be installed, and AS OF the documentation, will have to install it manually: https://laravel.com/docs/master/mail#driver-prerequisites

composer require guzzlehttp/guzzle

I know that question is a bit old but

In root of project where Pipfile is located you could run

pipenv --venv

which returns

/Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

and then remove this env by typing

rm -rf /Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

So for me the problem was that I had created my GitLab account via linking my GitHub account to it. This meant that no password formally existed for the account as it was created via hotlink between GitHub and GitLab. I fixed it by going to GitLab Settings -> Password -> and writing the same password as my GitHub account had.

The above method worked for me but since it was something I needed often, I used a basic method for flat object. Note, I was also using Vue and not REACT

packageData: (data) => {
  const form = new FormData()
  for ( const key in data ) {
    form.append(key, data[key]);
  }
  return form
}

Which worked for me until I ran into more complex data structures with nested objects and files which then let to the following

packageData: (obj, form, namespace) => {
  for(const property in obj) {
    // if form is passed in through recursion assign otherwise create new
    const formData = form || new FormData()
    let formKey

    if(obj.hasOwnProperty(property)) {
      if(namespace) {
        formKey = namespace + '[' + property + ']';
      } else {
        formKey = property;
      }

      // if the property is an object, but not a File, use recursion.
      if(typeof obj[property] === 'object' && !(obj[property] instanceof File)) {
        packageData(obj[property], formData, property);
      } else {
        // if it's a string or a File
      formData.append(formKey, obj[property]);
      }
    }
  }
  return formData;
}

I have added dataType: 'jsonp' and it works!

$.ajax({
   type: 'POST',
   crossDomain: true,
   dataType: 'jsonp',
   url: '',
   success: function(jsondata){

   }
})

JSONP is a method for sending JSON data without worrying about cross-domain issues. Read More

I suggest to use this plugin flutter_easyloading

flutter_easyloading is clean and lightweight Loading widget for Flutter App, easy to use without context, support iOS and Android

Add this to your package's pubspec.yaml file:

dependencies:
  flutter_easyloading: ^2.0.0

Now in your Dart code, you can use:

import 'package:flutter_easyloading/flutter_easyloading.dart';

To use First, initialize FlutterEasyLoading in MaterialApp/CupertinoApp

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter EasyLoading',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter EasyLoading'),
      builder: EasyLoading.init(),
    );
  }
}

EasyLoading is a singleton, so you can custom loading style any where like this:

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter_easyloading/flutter_easyloading.dart';
import './custom_animation.dart';

void main() {
  runApp(MyApp());
  configLoading();
}

void configLoading() {
  EasyLoading.instance
    ..displayDuration = const Duration(milliseconds: 2000)
    ..indicatorType = EasyLoadingIndicatorType.fadingCircle
    ..loadingStyle = EasyLoadingStyle.dark
    ..indicatorSize = 45.0
    ..radius = 10.0
    ..progressColor = Colors.yellow
    ..backgroundColor = Colors.green
    ..indicatorColor = Colors.yellow
    ..textColor = Colors.yellow
    ..maskColor = Colors.blue.withOpacity(0.5)
    ..userInteractions = true
    ..customAnimation = CustomAnimation();
}

Then, use per your requirement

import 'package:flutter/material.dart';
import 'package:flutter_easyloading/flutter_easyloading.dart';
import 'package:dio/dio.dart';

class TestPage extends StatefulWidget {
  @override
  _TestPageState createState() => _TestPageState();
}

class _TestPageState extends State<TestPage> {
  @override
  void initState() {
    super.initState();
    // EasyLoading.show();
  }

  @override
  void deactivate() {
    EasyLoading.dismiss();
    super.deactivate();
  }

  void loadData() async {
    try {
      EasyLoading.show();
      Response response = await Dio().get('https://github.com');
      print(response);
      EasyLoading.dismiss();
    } catch (e) {
      EasyLoading.showError(e.toString());
      print(e);
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter EasyLoading'),
      ),
      body: Center(
        child: FlatButton(
          textColor: Colors.blue,
          child: Text('loadData'),
          onPressed: () {
            loadData();
            // await Future.delayed(Duration(seconds: 2));
            // EasyLoading.show(status: 'loading...');
            // await Future.delayed(Duration(seconds: 5));
            // EasyLoading.dismiss();
          },
        ),
      ),
    );
  }
}

Update:

According @noraj's answer and @Niels Kristian's comment, the following command should do the job.

gem update --system
bundle install

I wrote this in case someone gets into an issue like mine.

gem install bundler shows that everythings installs well.

Fetching: bundler-1.16.0.gem (100%)
Successfully installed bundler-1.16.0
Parsing documentation for bundler-1.16.0

When I typed bundle there was an error:

/Users/nikkov/.rvm/gems/ruby-2.4.0/bin/bundle:23:in `load': cannot load such file -- /Users/nikkov/.rvm/rubies/ruby-2.4.0/lib/ruby/gems/2.4.0/gems/bundler-1.16.0/exe/bundle (LoadError)

And in the folder /Users/nikkov/.rvm/rubies/ruby-2.4.0/lib/ruby/gems/2.4.0/gems/ there wasn't a bundler-1.16.0 folder.

I fixed this with sudo gem install bundler

The command git config --list will list the settings. There you should also find user.name and user.email.

If you are matching with sqlite database:
In your php folder open php.ini file, go to:

;extension=pdo_sqlite

Just remove the semicolon and it will work.

Note for Chrome Browser released in 2020.

A future release of Chrome will only deliver cookies with cross-site requests if they are set with SameSite=None and Secure.

So if your backend server does not set SameSite=None, Chrome will use SameSite=Lax by default and will not use this cookie with { withCredentials: true } requests.

More info https://www.chromium.org/updates/same-site.

Firefox and Edge developers also want to release this feature in the future.

Spec found here: https://tools.ietf.org/html/draft-west-cookie-incrementalism-01#page-8

Without adding additional dependencies, this works. You don't need Volley for this. This works using the current version of Kotlin as of Dec 2018: Kotlin 1.3.10

If using Android Studio, you'll need to add this declaration in your AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

You should manually declare imports here. The auto-import tool caused me many conflicts.:

import android.os.AsyncTask
import java.io.BufferedReader
import java.io.InputStreamReader
import java.io.OutputStream
import java.io.OutputStreamWriter
import java.net.URL
import java.net.URLEncoder
import javax.net.ssl.HttpsURLConnection

You can't perform network requests on a background thread. You must subclass AsyncTask.

To call the method:

NetworkTask().execute(requestURL, queryString)

Declaration:

private class NetworkTask : AsyncTask<String, Int, Long>() {
    override fun doInBackground(vararg parts: String): Long? {
        val requestURL = parts.first()
        val queryString = parts.last()

        // Set up request
        val connection: HttpsURLConnection = URL(requestURL).openConnection() as HttpsURLConnection
        // Default is GET so you must override this for post
        connection.requestMethod = "POST"
        // To send a post body, output must be true
        connection.doOutput = true
        // Create the stream
        val outputStream: OutputStream = connection.outputStream
        // Create a writer container to pass the output over the stream
        val outputWriter = OutputStreamWriter(outputStream)
        // Add the string to the writer container
        outputWriter.write(queryString)
        // Send the data
        outputWriter.flush()

        // Create an input stream to read the response
        val inputStream = BufferedReader(InputStreamReader(connection.inputStream)).use {
            // Container for input stream data
            val response = StringBuffer()
            var inputLine = it.readLine()
            // Add each line to the response container
            while (inputLine != null) {
                response.append(inputLine)
                inputLine = it.readLine()
            }
            it.close()
            // TODO: Add main thread callback to parse response
            println(">>>> Response: $response")
        }
        connection.disconnect()

        return 0
    }

    protected fun onProgressUpdate(vararg progress: Int) {
    }

    override fun onPostExecute(result: Long?) {
    }
}

Mutations expect two arguments: state and payload, where the current state of the store is passed by Vuex itself as the first argument and the second argument holds any parameters you need to pass.

The easiest way to pass a number of parameters is to destruct them:

mutations: {
    authenticate(state, { token, expiration }) {
        localStorage.setItem('token', token);
        localStorage.setItem('expiration', expiration);
    }
}

Then later on in your actions you can simply

store.commit('authenticate', {
    token,
    expiration,
});

I had a similar issue and solved after running these instructions!

npm install npm -g
npm install --save-dev @angular/cli@latest
npm install
npm start

If you are using Android Studio 3.0, add the Google maven repository as shown below:

allprojects {
  repositories {
    jcenter()
    google()
 }
}

In my legacy app Array.from of prototype js was conflicting with angular's Array.from that was causing this problem. I resolved it by saving angular's Array.from version and reassigning it after prototype load.

In case none of the aforementioned solutions works for you, then simply do the under changes. Change this

$cfg['Servers'][$i]['host'] = '127.0.0.1';

to

$cfg['Servers'][$i]['host'] = 'localhost';

and

$cfg['Servers'][$i]['auth_type'] = 'config';

to

$cfg['Servers'][$I]['auth_type'] ='cookies';

It works in my situation, possibly works on your situation also.

You can use either HttpClient or RestSharp. Since I do not know what your code is, here is an example using HttpClient:

using (var client = new HttpClient())
{
    // This would be the like http://www.uber.com
    client.BaseAddress = new Uri("Base Address/URL Address");

    // serialize your json using newtonsoft json serializer then add it to the StringContent
    var content = new StringContent(YourJson, Encoding.UTF8, "application/json") 

    // method address would be like api/callUber:SomePort for example
    var result = await client.PostAsync("Method Address", content);
    string resultContent = await result.Content.ReadAsStringAsync();   
}

The 2nd parameter of http.post is the body of the message, ie the payload and not the url search parameters. Pass data in that parameter.

From the documentation

post(url: string, body: any, options?: RequestOptionsArgs) : Observable<Response>

public post(cmd: string, data: object): Observable<any> {

    const params = new URLSearchParams();
    params.set('cmd', cmd);

    const options = new RequestOptions({
      headers: this.getAuthorizedHeaders(),
      responseType: ResponseContentType.Json,
      params: params,
      withCredentials: false
    });

    console.log('Options: ' + JSON.stringify(options));

    return this.http.post(this.BASE_URL, data, options)
      .map(this.handleData)
      .catch(this.handleError);
  }

Edit

You should also check out the 1st parameter (BASE_URL). It must contain the complete url (minus query string) that you want to reach. I mention in due to the name you gave it and I can only guess what the value currently is (maybe just the domain?).

Also there is no need to call JSON.stringify on the data/payload that is sent in the http body.

If you still can't reach your end point look in the browser's network activity in the development console to see what is being sent. You can then further determine if the correct end point is being called wit the correct header and body. If it appears that is correct then use POSTMAN or Fiddler or something similar to see if you can hit your endpoint that way (outside of Angular).

To expand on user8266077's answer, I found that I still needed to supply OPTIONS response for preflight requests in .NET Core 2.1-preview for my use case:

// https://stackoverflow.com/a/45844400
public class CorsMiddleware
{
  private readonly RequestDelegate _next;

  public CorsMiddleware(RequestDelegate next)
  {
    _next = next;
  }

  public async Task Invoke(HttpContext context)
  {
    context.Response.Headers.Add("Access-Control-Allow-Origin", "*");
    context.Response.Headers.Add("Access-Control-Allow-Credentials", "true");
    // Added "Accept-Encoding" to this list
    context.Response.Headers.Add("Access-Control-Allow-Headers", "Content-Type, X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Accept-Encoding, Content-Length, Content-MD5, Date, X-Api-Version, X-File-Name");
    context.Response.Headers.Add("Access-Control-Allow-Methods", "POST,GET,PUT,PATCH,DELETE,OPTIONS");
    // New Code Starts here
    if (context.Request.Method == "OPTIONS")
    {
      context.Response.StatusCode = (int)HttpStatusCode.OK;
      await context.Response.WriteAsync(string.Empty);
    }
    // New Code Ends here

    await _next(context);
  }
}

and then enabled the middleware like so in Startup.cs

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
  app.UseMiddleware(typeof(CorsMiddleware));
  // ... other middleware inclusion such as ErrorHandling, Caching, etc
  app.UseMvc();
}

I believe TLSV1_ALERT_PROTOCOL_VERSION is alerting you that the server doesn't want to talk TLS v1.0 to you. Try to specify TLS v1.2 only by sticking in these lines:

import ssl
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1_2)

# Create HTTPS connection
c = HTTPSConnection("0.0.0.0", context=context)

Note, you may need sufficiently new versions of Python (2.7.9+ perhaps?) and possibly OpenSSL (I have "OpenSSL 1.0.2k 26 Jan 2017" and the above seems to work, YMMV)

I think it has to do with your second element in storbinary. You are trying to open file, but it is already a pointer to the file you opened in line file = open(local_path,'rb'). So, try to use ftp.storbinary("STOR " + i, file).

The reason the code in your question does not authenticate is because you are sending the auth in the data object, not in the config, which will put it in the headers. Per the axios docs, the request method alias for post is:

axios.post(url[, data[, config]])

Therefore, for your code to work, you need to send an empty object for data:

var session_url = 'http://api_address/api/session_endpoint';
var username = 'user';
var password = 'password';
var basicAuth = 'Basic ' + btoa(username + ':' + password);
axios.post(session_url, {}, {
  headers: { 'Authorization': + basicAuth }
}).then(function(response) {
  console.log('Authenticated');
}).catch(function(error) {
  console.log('Error on Authentication');
});

The same is true for using the auth parameter mentioned by @luschn. The following code is equivalent, but uses the auth parameter instead (and also passes an empty data object):

var session_url = 'http://api_address/api/session_endpoint';
var uname = 'user';
var pass = 'password';
axios.post(session_url, {}, {
  auth: {
    username: uname,
    password: pass
  }
}).then(function(response) {
  console.log('Authenticated');
}).catch(function(error) {
  console.log('Error on Authentication');
});

I was working with Spring REST, and I solved it adding the AllowedMethods into the WebMvcConfigurer.

@Value( "${app.allow.origins}" )
    private String allowOrigins;    
@Bean
public WebMvcConfigurer corsConfigurer() {
            System.out.println("allow origin: "+allowOrigins);
            return new WebMvcConfigurerAdapter() {
                @Override
                public void addCorsMappings(CorsRegistry registry) {
                    registry.addMapping("/**")
                    //.allowedOrigins("http://localhost")
                    .allowedOrigins(allowOrigins)
                    .allowedMethods("PUT", "DELETE","GET", "POST");
                }
            };
        }

The following code worked for me:

echo userInput

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

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


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

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

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

Another way besides @Nahush's answer, if you are already using Express framework in the project then you can avoid using Nginx for reverse-proxy.

A simpler way is to use express-http-proxy

1. run npm run build to create the bundle.

   var proxy = require('express-http-proxy');
   
   var app = require('express')();
   
   //define the path of build
   
   var staticFilesPath = path.resolve(__dirname, '..', 'build');
   
   app.use(express.static(staticFilesPath));
   
   app.use('/api/api-server', proxy('www.api-server.com'));
   

Use "/api/api-server" from react code to call the API.

So, that browser will send request to the same host which will be internally redirecting the request to another server and the browser will feel that It is coming from the same origin ;)

This issue can occur if the Azure Active Directory Module for Windows PowerShell isn't loaded correctly.

To resolve this issue, follow these steps.
1.Install the Azure Active Directory Module for Windows PowerShell on the computer (if it isn't already installed). To install the Azure Active Directory Module for Windows PowerShell, go to the following Microsoft website:
Manage Azure AD using Windows PowerShell

2.If the MSOnline module isn't present, use Windows PowerShell to import the MSOnline module.

Import-Module MSOnline 

After it complete, we can use this command to check it.

PS C:\Users> Get-Module -ListAvailable -Name MSOnline*


    Directory: C:\windows\system32\WindowsPowerShell\v1.0\Modules

You can pass boolean by coercing it, put !! before the variable.

let isRequired = '' || null || undefined
<input :required="!!isRequired"> // it will coerce value to respective boolean 

But I would like to pull your attention for the following case where the receiving component has defined type for props. In that case, if isRequired has defined type to be string then passing boolean make it type check fails and you will get Vue warning. To fix that you may want to avoid passing that prop, so just put undefined fallback and the prop will not sent to component

let isValue = false
<any-component
  :my-prop="isValue ? 'Hey I am when the value exist' : undefined"
/>

Explanation

I have been through the same problem, and tried above solutions !! Yes, I don't see the prop but that actually does not fulfils what required here.

My problem -

let isValid = false
<any-component
  :my-prop="isValue ? 'Hey I am when the value exist': false"
/>

In the above case, what I expected is not having my-prop get passed to the child component - <any-conponent/> I don't see the prop in DOM but In my <any-component/> component, an error pops out of prop type check failure. As in the child component, I am expecting my-prop to be a String but it is boolean.

myProp : {
 type: String,
 required: false,
 default: ''
}

Which means that child component did receive the prop even if it is false. Tweak here is to let the child component to take the default-value and also skip the check. Passed undefined works though!

<any-component
  :my-prop="isValue ? 'Hey I am when the value exist' : undefined"
/>
 

This works and my child prop is having the default value.

Http 415 Media Unsupported is responded back only when the content type header you are providing is not supported by the application.

With POSTMAN, the Content-type header you are sending is Content type 'multipart/form-data not application/json. While in the ajax code you are setting it correctly to application/json. Pass the correct Content-type header in POSTMAN and it will work.

You should only access Linux files system (those located in lxss folder) from inside WSL; DO NOT create/modify any files in lxss folder in Windows - it's dangerous and WSL will not see these files.

Files can be shared between WSL and Windows, though; put the file outside of lxss folder. You can access them via drvFS (/mnt) such as /mnt/c/Users/yourusername/files within WSL. These files stay synced between WSL and Windows.

For details and why, see: https://blogs.msdn.microsoft.com/commandline/2016/11/17/do-not-change-linux-files-using-windows-apps-and-tools/

I had everything fine. Less secure app option was also enabled. Still, I was getting the error. What I have done is:

• Google will send you Critical security alert
• Then you have to authorize that activity. ( Clicking on 'YES, THAT WAS ME' type thing )
• Then you can try sending email again.

You can try this:

create procedure [dbo].[get_user_names]
    @user_id_list varchar(2000), -- You can use any max length

    @username varchar (30) output
    as
    select last_name+', '+first_name 
    from user_mstr
    where user_id in (Select ID from dbo.SplitString( @user_id_list, ',') )

And here is the user defined function for SplitString:

Create FUNCTION [dbo].[SplitString]
(    
      @Input NVARCHAR(MAX),
      @Character CHAR(1)
)
RETURNS @Output TABLE (
      Item NVARCHAR(1000)
)
AS
BEGIN
      DECLARE @StartIndex INT, @EndIndex INT

      SET @StartIndex = 1
      IF SUBSTRING(@Input, LEN(@Input) - 1, LEN(@Input)) <> @Character
      BEGIN
            SET @Input = @Input + @Character
      END

      WHILE CHARINDEX(@Character, @Input) > 0
      BEGIN
            SET @EndIndex = CHARINDEX(@Character, @Input)

            INSERT INTO @Output(Item)
            SELECT SUBSTRING(@Input, @StartIndex, @EndIndex - 1)

            SET @Input = SUBSTRING(@Input, @EndIndex + 1, LEN(@Input))
      END

      RETURN
END

I resolved this issue by setting an email address in Git:

git config --global user.email "[email protected]"

I think the simplest way is that:

type InputEvent = React.ChangeEvent<HTMLInputElement>;
type ButtonEvent = React.MouseEvent<HTMLButtonElement>;

update = (e: InputEvent): void => this.props.login[e.target.name] = e.target.value;
submit = (e:  ButtonEvent): void => {
    this.props.login.logIn();
    e.preventDefault();
}

As of Angular 8+ you can use clear() to remove all controls in the FormArray:

const arr = new FormArray([
   new FormControl(),
   new FormControl()
]);
console.log(arr.length);  // 2

arr.clear();
console.log(arr.length);  // 0

For previous versions the recommended way is:

while (arr.length) {
   arr.removeAt(0);
}

https://angular.io/api/forms/FormArray#clear

To send a message to a user you first need a User instance representing the user you want to send the message to.

Obtaining a User instance

• You can obtain a User instance from a message the user sent by doing message.autor
• You can obtain a User instance from a user id with client.fetchUser

Once you got a user instance you can send the message with .send

Examples

client.on('message', (msg) => {
 if (!msg.author.bot) msg.author.send('ok ' + msg.author.id);
});

client.fetchUser('487904509670337509', false).then((user) => {
 user.send('heloo');
});

UsernamePasswordAuthenticationFilter is only used for /login, and latter filters are not?

No, UsernamePasswordAuthenticationFilter extends AbstractAuthenticationProcessingFilter, and this contains a RequestMatcher, that means you can define your own processing url, this filter only handle the RequestMatcher matches the request url, the default processing url is /login.

Later filters can still handle the request, if the UsernamePasswordAuthenticationFilter executes chain.doFilter(request, response);.

More details about core fitlers

Does the form-login namespace element auto-configure these filters?

UsernamePasswordAuthenticationFilter is created by <form-login>, these are Standard Filter Aliases and Ordering

Does every request (authenticated or not) reach FilterSecurityInterceptor for non-login url?

It depends on whether the before fitlers are successful, but FilterSecurityInterceptor is the last fitler normally.

Does configuring two http elements create two springSecurityFitlerChains?

Yes, every fitlerChain has a RequestMatcher, if the RequestMatcher matches the request, the request will be handled by the fitlers in the fitler chain.

The default RequestMatcher matches all request if you don't config the pattern, or you can config the specific url (<http pattern="/rest/**").

If you want to konw more about the fitlers, I think you can check source code in spring security. doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)

While the previous solutions are very correct, if you absolutely need the feature then you can mimic the situation with custom input using text-field and JavaScript.

For secure usage, you can use any cryptography technique. So this way you will bypass the browser's password saving behavior.

If you want to know more about the idea, we can discuss that on chat. But the gist is discussed in previous answers and you can get the idea.

There are 2 inputs you might have and you can also convert between them.

1. input: listOfDictionaries --> use @VikashSingh solution

example: [{"":{"...

The pd.DataFrame() needs a listOfDictionaries as input.

2. input: jsonStr --> use @JustinMalinchak solution

example: '{"":{"...

If you have jsonStr, you need an extra step to listOfDictionaries first. This is obvious as it is generated like:

jsonStr = json.dumps(listOfDictionaries)

Thus, switch back from jsonStr to listOfDictionaries first:

listOfDictionaries = json.loads(jsonStr)

If you are sure that the modification in the SQL file has no impact on your existing schema, you can also update the checksum of the existing schema.

I did this following a slight change in the sql file.

Here is how I updated the checksum:

update flyway_schema_history set checksum = '-1934991199' where installed_rank = '1';

How about using IIF?

SELECT IIF (EXISTS (SELECT 1 FROM tblGLUserAccess WHERE GLUserName ='xxxxxxxx'), 1, 2)

Also, if using EXISTS to check the the existence of rows, don't use *, just use 1. I believe it has the least cost.

use this

response.body().get(0).getUsername().toString();

I had same problem, i am trying to login database it appear a message with: "ORA-28001: The password has expired" , I have fixed the problem simple steps

1.open command prompt 2.type sqlplus 3.It will ask Enter Password, you can give old password, it will show password has expired ORA-28001 4.It will ask new password and retype password 5.It will change with new password 6.Go to the sql database and try to connect with new password, it will connect.

You misread the documentation. You need to do two things:

1. Quote each key and value from your dictionary, and
2. Encode those into a URL

Luckily urllib.parse.urlencode does both those things in a single step, and that's the function you should be using.

from urllib.parse import urlencode, quote_plus

payload = {'username':'administrator', 'password':'xyz'}
result = urlencode(payload, quote_via=quote_plus)
# 'password=xyz&username=administrator'

Try to use git clone XXX if you'd see LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to XXX it might be the case that just updated your OS, installed some dev tools, e.g. Xcode with its tools on Mac, VPN, Antivirus (especially Kaspersky Antivirus) or something between/other.

In my case simply restarting my OS (macOS Catalina) fixed this issue.

if it is coming from server as object you can do 

this.service.subscribe(data:any) keep any type on data it will solve the issue

I had a similar problem but with the specific requirement to have the CORS header set from decorators in our endpoints, like this:

@CrossOrigin(origins = "*", allowCredentials = "true")
@PostMapping(value = "/login")

Or

@CrossOrigin(origins = "*")
@GetMapping(value = "/verificationState")

So simply intercepting the request, setting the CORS header manually and sending 200 back was not an option, because allowCredentials was needed to be true in some cases and wildcards are not allowed then. Sure, a CORS registry would have helped, but since our clients are angular in capacitor on android and iOS, there is no specific domain to register. So the clean way to do - in my opinion - is to pipe preflights directly to the endpoints to let them handle it. I solved it with this:

@Component
public class PreflightFilter extends OncePerRequestFilter {

    private static final Logger logger = LoggerFactory.getLogger(PreflightFilter.class);

    @Override
    protected void doFilterInternal(HttpServletRequest request,
                                    HttpServletResponse response, FilterChain chain)
            throws ServletException, IOException {

        if (CorsUtils.isPreFlightRequest(request)) {
            logger.info("Preflight request accepted");
            SecurityContextHolder.getContext().setAuthentication(createPreflightToken(request));
        }
        chain.doFilter(request, response);
    }

    private UsernamePasswordAuthenticationToken createPreflightToken(HttpServletRequest request) {
        UserDetails userDetails = new User("Preflight", "",
                true, true, true, true,
                Stream.of(new SimpleGrantedAuthority("AppUser")).collect(Collectors.toSet()));
        UsernamePasswordAuthenticationToken preflightToken =
                new UsernamePasswordAuthenticationToken(
                        userDetails, null, userDetails.getAuthorities());
        preflightToken
                .setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
        return preflightToken;
    }
}

Keep in mind that the endpoint decorators don't work like wildcards here as one would expect!

Adding a space before the EOF delimiter allows to avoid cmd:

- shell: |
    cat <<' EOF'
    This is a test.
    EOF

I know it may be repeated answer but for any one want to load list of checkboxes with selectall checkbox into angular form i follow this example: Select all/deselect all checkbox using angular 2+

it work fine but just need to add

[ngModelOptions]="{standalone: true}" 

the final HTML should be like this:

<ul>
    <li><input type="checkbox" [(ngModel)]="selectedAll" (change)="selectAll();"/></li>
    <li *ngFor="let n of names">
    <input type="checkbox" [(ngModel)]="n.selected" (change)="checkIfAllSelected();">{{n.name}}
    </li>
  </ul>

TypeScript

  selectAll() {
    for (var i = 0; i < this.names.length; i++) {
      this.names[i].selected = this.selectedAll;
    }
  }
  checkIfAllSelected() {
    this.selectedAll = this.names.every(function(item:any) {
        return item.selected == true;
      })
  }

hope this help thnx

use @Id .Worked for me.Otherwise it i will throw error.It depends on is there anything missing in your entity class or repository

Posting it here as it might help others. In string it might be necessary to pass the quotes to jq. To do the following with jq:

.items[] | select(.name=="string")

in bash you could do

EMAILID=$1
projectID=$(cat file.json | jq -r '.resource[] | select(.username=='\"$EMAILID\"') | .id')

essentially escaping the quotes and passing it on to jq

By default, when you fetch your URL, React native sets the cookie.

To see cookies and make sure that you can use the https://www.npmjs.com/package/react-native-cookie package. I used to be very satisfied with it.

Of course, Fetch does this when it does

credentials: "include",// or "some-origin"

Well, but how to use it

--- after installation this package ----

to get cookies:

import Cookie from 'react-native-cookie';

Cookie.get('url').then((cookie) => {
   console.log(cookie);
});

to set cookies:

Cookie.set('url', 'name of cookies', 'value  of cookies');

only this

But if you want a few, you can do it

1- as nested:

Cookie.set('url', 'name of cookies 1', 'value  of cookies 1')
        .then(() => {
            Cookie.set('url', 'name of cookies 2', 'value  of cookies 2')
            .then(() => {
                ...
            })
        })

2- as back together

Cookie.set('url', 'name of cookies 1', 'value  of cookies 1');
Cookie.set('url', 'name of cookies 2', 'value  of cookies 2');
Cookie.set('url', 'name of cookies 3', 'value  of cookies 3');
....

Now, if you want to make sure the cookies are set up, you can get it again to make sure.

Cookie.get('url').then((cookie) => {
  console.log(cookie);
});

1. Delete early created devices.
2. Close Android studio.
3. Open: Control panel -> System & security -> System -> Advanced system settings -> Environment variables.
4. Create New variable "ANDROID_SDK_HOME" and set new path(in my case it was F:\Coding2019\Android\AVDdevices). Push 'ok'.
5. Open Android Studio.
6. Create new device. After creating in drop-down menu click "View Details" to see new path of new AVD.

You are mixing the deprecated mysql extension with mysqli.

Try something like:

$sql = mysqli_query($success, "SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysqli_num_rows($sql);

Ok. I found problem.

It was not on the Angular side. To be honest, there were no problem at all.

Reason why I was unable to perform my request succesfuly was that my server app was not properly handling OPTIONS request.

Why OPTIONS, not POST? My server app is on different host, then frontend. Because of CORS my browser was converting POST to OPTION: http://restlet.com/blog/2015/12/15/understanding-and-using-cors/

With help of this answer: Standalone Spring OAuth2 JWT Authorization Server + CORS

I implemented proper filter on my server-side app.

Thanks to @Supamiu - the person which fingered me that I am not sending POST at all.

The best solution, you can manage the multiple node versions using nvm installer. then, install the required node's version using below command

nvm install version

Use below command as a working node with mentioned version alone

nvm use version

now, you can use any version node without uninstalling previous installed node.

This is more the the error itself, not answering the original question:

We were migrating from java 8 to java 11. Application compiled successfully, but the errors Unable to find a @SpringBootConfiguration started to appear in the integration tests when ran from command line using maven (from IntelliJ it worked).

It appeared that maven-failsafe-plugin stopped seeing the classes on classpath, we fixed that by telling failsafe plugin to include the classes manually:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-failsafe-plugin</artifactId>
            <configuration>
                <additionalClasspathElements>
                    <additionalClasspathElement>${basedir}/target/classes</additionalClasspathElement>
                </additionalClasspathElements>
            </configuration>
            ...
        </plugin>

To use this only for specific controllers for example use this:

app.UseWhen(x => (x.Request.Path.StartsWithSegments("/api", StringComparison.OrdinalIgnoreCase)), 
            builder =>
            {
                builder.UseMiddleware<AuthenticationMiddleware>();
            });

Hi We sort of had the same problem if I understand you well. So check what pysftp version you're using. If it's the latest one which is 0.2.9 downgrade to 0.2.8. Check this out. https://github.com/Yenthe666/auto_backup/issues/47

In addition to previously provided answers, one option is to follow the 'localhost exception' approach to create the first user if your db is already started with access control (--auth switch). In order to do that, you need to have localhost access to the server and then run:

mongo
use admin
db.createUser(
 {
     user: "user_name",
     pwd: "user_pass",
     roles: [
           { role: "userAdminAnyDatabase", db: "admin" },
           { role: "readWriteAnyDatabase", db: "admin" },
           { role: "dbAdminAnyDatabase", db: "admin" }
        ]
 })

As stated in MongoDB documentation:

The localhost exception allows you to enable access control and then create the first user in the system. With the localhost exception, after you enable access control, connect to the localhost interface and create the first user in the admin database. The first user must have privileges to create other users, such as a user with the userAdmin or userAdminAnyDatabase role. Connections using the localhost exception only have access to create the first user on the admin database.

Here is the link to that section of the docs.

The then method returns a pending promise which can be resolved asynchronously by the return value of a result handler registered in the call to then, or rejected by throwing an error inside the handler called.

So calling AuthUser will not suddenly log the user in synchronously, but returns a promise whose then registered handlers will be called after the login succeeds ( or fails). I would suggest triggering all login processing by a then clause of the login promise. E.G. using named functions to highlight the sequence of flow:

let AuthUser = data => {   // just the login promise
  return google.login(data.username, data.password);
};

AuthUser(data).then( processLogin).catch(loginFail);

function processLogin( token) {
      // do logged in stuff:
      // enable, initiate, or do things after login
}
function loginFail( err) {
      console.log("login failed: " + err);
}

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:

x = ["0", "1", "2"] 
y = int(x[0]) #accessing the zeroth element

If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:

x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)

If your list elements are not strings, you'll have to convert them to strings before using str.join:

x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)

Also, as stated above, make sure that you're not returning a nested list.

You didn't tell us what particular problem do you have with the WinSCP, so I can really only repeat what's in WinSCP documentation.

• Download WinSCP .NET assembly.
  The latest package as of now is WinSCP-5.17.10-Automation.zip;

• Extract the .zip archive along your script;

• Use a code like this (based on the official PowerShell upload example):

    # Load WinSCP .NET assembly
    Add-Type -Path "WinSCPnet.dll"
  
    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "example.com"
        UserName = "user"
        Password = "mypassword"
        SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="
    }
  
    $session = New-Object WinSCP.Session
  
    try
    {
        # Connect
        $session.Open($sessionOptions)
  
        # Upload
        $session.PutFiles("C:\FileDump\export.txt", "/Outbox/").Check()
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }
  

You can have WinSCP generate the PowerShell script for the upload for you:

• Login to your server with WinSCP GUI;
• Navigate to the target directory in the remote file panel;
• Select the file for upload in the local file panel;
• Invoke the Upload command;
• On the Transfer options dialog, go to Transfer Settings > Generate Code;
• On the Generate transfer code dialog, select the .NET assembly code tab;
• Choose PowerShell language.

You will get a code like above with all session and transfer settings filled in.

1. Go and Check if a user is created or not if no please create a user by opening a file in /apache-tomcat-9.0.20/tomcat-users.xml add a line into it

   <user username="tomcat" password="tomcat" roles="admin-gui,manager-gui,manager-script" />

2. Goto /apache-tomcat-9.0.20/webapps/manager/META-INF/ open context.xml comment everything in context tag example:

<Context antiResourceLocking="false" privileged="true" >
     <!--Valve className="org.apache.catalina.valves.RemoteAddrValve"
            allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" /-->
   </Context>

if your springfox version higher than 2.5, should be add WebSecurityConfiguration as below:

@Override
public void configure(HttpSecurity http) throws Exception {
    // TODO Auto-generated method stub
    http.authorizeRequests()
        .antMatchers("/v2/api-docs", "/swagger-resources/configuration/ui", "/swagger-resources", "/swagger-resources/configuration/security", "/swagger-ui.html", "/webjars/**").permitAll()
        .and()
        .authorizeRequests()
        .anyRequest()
        .authenticated()
        .and()
        .csrf().disable();
}

I had a semicolon at the end, and gave me this error.

There are two problems in your code.

1. No action found in form.
2. You have not executed the query mysqli_query()

dbConfig.php

<?php

$conn=mysqli_connect("localhost","root","password","testDB");

if(!$conn)

When I started learning Spring Security, then I overrided the method userDetailsService() as in below code snippet:

@Configuration
@EnableWebSecurity
public class ApplicationSecurityConfiguration extends WebSecurityConfigurerAdapter{

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .authorizeRequests()
                .antMatchers("/", "/index").permitAll()
                .anyRequest().authenticated()
                .and()
                .httpBasic();
    }

    @Override
    @Bean
    public UserDetailsService userDetailsService() {
        List<UserDetails> users= new ArrayList<UserDetails>();
        users.add(User.withDefaultPasswordEncoder().username("admin").password("nimda").roles("USER","ADMIN").build());
        users.add(User.withDefaultPasswordEncoder().username("Spring").password("Security").roles("USER").build());
        return new InMemoryUserDetailsManager(users);
    }
}

So we can log in to the application using the above-mentioned creds. (e.g. admin/nimda)

Note: This we should not use in production.

Small hint which other people didn't talk about: git doesn't record changes if you add empty folders in your project folder. That's it, I was adding empty folders with random names to check wether it was recording changes, it wasn't. But it started to do it as soon as I began adding files in them. Cheers.

I got the same error when installed both python2 and python3 on my Windows 7.

You can use python3 -m pip install xxxxxx to install your package.

Or, fix it completely:

1. Try to run python3 -m pip install --upgrade pip in cmd.

2. If failed in step 1, try python3  -m pip install --upgrade --force-reinstall pip

Vue watch() life-cycle hook, can be used

html

<div id="demo">{{ fullName }}</div>

js

var vm = new Vue({
  el: '#demo',
  data: {
    firstName: 'Foo',
    lastName: 'Bar',
    fullName: 'Foo Bar'
  },
  watch: {
    firstName: function (val) {
      this.fullName = val + ' ' + this.lastName
    },
    lastName: function (val) {
      this.fullName = this.firstName + ' ' + val
    }
  }
})

Each deployed webapp has a context.xml file that lives in

$CATALINA_BASE/conf/[enginename]/[hostname]

(conf/Catalina/localhost by default)

and has the same name as the webapp (manager.xml in this case). If no file is present, default values are used.

So, you need to create a file conf/Catalina/localhost/manager.xml and specify the rule you want to allow remote access. For example, the following content of manager.xml will allow access from all machines:

<Context privileged="true" antiResourceLocking="false" 
         docBase="${catalina.home}/webapps/manager">
    <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="^YOUR.IP.ADDRESS.HERE$" />
</Context>

Note that the allow attribute of the Valve element is a regular expression that matches the IP address of the connecting host. So substitute your IP address for YOUR.IP.ADDRESS.HERE (or some other useful expression).

Other Valve classes cater for other rules (e.g. RemoteHostValve for matching host names). Earlier versions of Tomcat use a valve class org.apache.catalina.valves.RemoteIpValve for IP address matching.

Once the changes above have been made, you should be presented with an authentication dialog when accessing the manager URL. If you enter the details you have supplied in tomcat-users.xml you should have access to the Manager.

I'm using reactive forms in angular 4 and this approach works for me:

    this.profileEditForm.reset(this.profileEditForm.value);

see reset the form flags in the Fundamentals doc

In my case, I had to do the following while running with Junit5

@SpringBootTest(classes = {abc.class}) @ExtendWith(SpringExtension.class

Here abc.class was the class that was being tested

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

you must stop another running app involved with especial database table ... like running java API in other module or other project is not terminated .. so terminate running.

Add this two line in your style.xml

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

I think it's safer to cache credentials, instead of store forever:

git config --global credential.helper 'cache --timeout=10800'

now you can enter your username and password(git pull or ...), and keep using git for next 3 hours.

nice and safe.

Timeout is in seconds(3 hours in the example).

First add the collections and then apply lookup on these collections. Don't use $unwind as unwind will simply separate all the documents of each collections. So apply simple lookup and then use $project for projection. Here is mongoDB query:

db.userInfo.aggregate([
    {
        $lookup: {
           from: "userRole",
           localField: "userId",
           foreignField: "userId",
           as: "userRole"
        }
    },
    {
        $lookup: {
            from: "userInfo",
            localField: "userId",
            foreignField: "userId",
            as: "userInfo"
        }
    },
    {$project: {
        "_id":0,
        "userRole._id":0,
        "userInfo._id":0
        }
        } ])

Here is the output:

/* 1 */ {
    "userId" : "AD",
    "phone" : "0000000000",
    "userRole" : [ 
        {
            "userId" : "AD",
            "role" : "admin"
        }
    ],
    "userInfo" : [ 
        {
            "userId" : "AD",
            "phone" : "0000000000"
        }
    ] }

Thanks.

You should be able to do the following:

$params = @{"@type"="login";
 "username"="[email protected]";
 "password"="yyy";
}

Invoke-WebRequest -Uri http://foobar.com/endpoint -Method POST -Body $params

This will send the post as the body. However - if you want to post this as a Json you might want to be explicit. To post this as a JSON you can specify the ContentType and convert the body to Json by using

Invoke-WebRequest -Uri http://foobar.com/endpoint -Method POST -Body ($params|ConvertTo-Json) -ContentType "application/json"

Extra: You can also use the Invoke-RestMethod for dealing with JSON and REST apis (which will save you some extra lines for de-serializing)

This error happen usually when tables in the query doesn't exist. Just check the table's spelling in the query, and it will work.

$Group is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string").

Change $Group.StartsWith("S_G_") to $Group.samaccountname.StartsWith("S_G_").

For Symfony users: Add a default to your orm column as follows:

/**
 * @var DateTime $updatedAt
 *
 * @ORM\Column(name="updated_at", type="datetime", nullable=false, options={"default" : "CURRENT_TIMESTAMP"})
 */

Using Spring context 5.0 I have successfully achieved loading correct property file based on system environment via the following annotation

@PropertySources({
    @PropertySource("classpath:application.properties"),
    @PropertySource("classpath:application-${MYENV:test}.properties")})

Here MYENV value is read from system environment and if system environment is not present then default test environment property file will be loaded, if I give a wrong MYENV value - it will fail to start the application.

Note: for each profile, you want to maintain - you will need to make an application-[profile].property file and although I used Spring context 5.0 & not Spring boot - I believe this will also work on Spring 4.1

If you're just playing around in local mode, you can drop metastore DB and reinstate it:

rm -rf metastore_db/
$HIVE_HOME/bin/schematool -initSchema -dbType derby

Cmdlets in powershell accept a bunch of arguments. When these arguments are defined you can define a position for each of them.

This allows you to call a cmdlet without specifying the parameter name. So for the following cmdlet the path attribute is define with a position of 0 allowing you to skip typing -Path when invoking it and as such both the following will work.

Get-Item -Path C:\temp\thing.txt
Get-Item C:\temp\thing.txt

However if you specify more arguments than there are positional parameters defined then you will get the error.

Get-Item C:\temp\thing.txt "*"

As this cmdlet does not know how to accept the second positional parameter you get the error. You can fix this by telling it what the parameter is meant to be.

Get-Item C:\temp\thing.txt -Filter "*"

I assume you are getting the error on the following line of code as it seems to be the only place you are not specifying the parameter names correctly, and maybe it is treating the = as a parameter and $username as another parameter.

Set-ADUser $user -userPrincipalName = $newname

Try specifying the parameter name for $user and removing the =

In my case, I was having the same error using docker and the trick was in setting in the .env file this DB_HOST=db where db is the name of the container running the database server.

var details = {
    'userName': '[email protected]',
    'password': 'Password!',
    'grant_type': 'password'
};

var formBody = [];
for (var property in details) {
  var encodedKey = encodeURIComponent(property);
  var encodedValue = encodeURIComponent(details[property]);
  formBody.push(encodedKey + "=" + encodedValue);
}
formBody = formBody.join("&");

fetch('http://identity.azurewebsites.net' + '/token', {
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/x-www-form-urlencoded'
  },
  body: formBody
})

it is so helpful for me and works without any error

Try this:

function someFunction(username, password) {
      return new Promise((resolve, reject) => {
        // Do something with the params username and password...
        if ( /* everything turned out fine */ ) {
          resolve("Stuff worked!");
        } else {
          reject(Error("It didn't work!"));
        }
      });
    }
    
    someFunction(username, password)
      .then((result) => {
        // Do something...
      })
      .catch((err) => {
        // Handle the error...
      });

If you have the PATH in your .bashrc file and are still getting

conda: command not found

Your terminal might not be looking for the bash file. Type bash in the terminal to insure you are in bash and then try: conda --version

You should install PDO on your server. Edit your php.ini (look at your phpinfo(), "Loaded Configuration File" line, to find the php.ini file path). Find and uncomment the following line (remove the ; character):

;extension=pdo_mysql.so

Then, restart your Apache server. For more information, please read the documentation.

I landed here when I was trying to do a similar thing. For a application/x-www-form-urlencoded content type, you could try to use this for the body:

var body = 'username' =myusername & 'password'=mypassword;

with what you tried doing the value assigned to body will be a string.

1. Open your SQL command line and type the following:

   SQL> connect / as sysdba
   

2. Once connected,you can enter the following query to get details of username and password:

   SQL> select username,password from dba_users;
   

3. This will list down the usernames,but passwords would not be visible.But you can identify the particular username and then change the password for that user. For changing the password,use the below query:

   SQL> alter user username identified by password;
   

4. Here username is the name of user whose password you want to change and password is the new password.

This work at least in the Debian Jessie image hosted by Google:

The way to enable to switch from you regular to the root user (AKA “super user”) after authentificating with your Google Computer Engine (GCE) User in the local environment (your Linux server in GCE) is pretty straight forward, in fact it just involves just one command to enable it and another every time to use it:

$ sudo passwd
Enter the new UNIX password: <your new root password>
Retype the new UNIX password: <your new root password>
passwd: password updated successfully

After executing the previous command and once logged with your GCE User you will be able to switch to root anytime by just entering the following command:

$ su
Password: <your newly created root password>
root@intance:/#

As we say in economics “caveat emptor” or buyer be aware: Using the root user is far from a best practice in system’s administration. Using it can be the cause a lot of trouble, from wiping everything in your drives and boot disks without a hiccup to many other nasty stuff that would be laborious to backtrack, troubleshoot and rebuilt. On the other hand, I have never met a SysAdmin that doesn’t think he knows better and root more than he should.

REMEMBER: We humans are programmed in such a way that given enough time at one at some point or another are going to press enter without taking into account that we have escalated to root and I can assure you that it will great source of pain, regret and extra work. PLEASE USE ROOT PRIVILEGES SPARSELY AND WITH EXTREME CARE.

Having said all the boring stuff, Have fun, live on the edge, life is short, you only get to live it once, the more you break the more you learn.

you don't have a bitbucket password because you log with google, but you can "reset" the password here https://bitbucket.org/account/password/reset/

you will receive an email to setup a new password and that's it.

The D-Bus error can be fixed with dbus-launch :

EncodedParams variable is redefined as params variable will not work. You need to have same predefined call to variable, otherwise it looks possible with a little more work. Cheers! json is not used to its full capabilities in php there are better ways to call json which I don't recall at the moment.

Running npm commands in Windows Powershell solved my issue.

Make sure you have not committed a typo as in my case

msyql_fetch_assoc should be mysql

Another option is to use showtext package which supports more types of fonts (TrueType, OpenType, Type 1, web fonts, etc.) and more graphics devices, and avoids using external software such as Ghostscript.

# install.packages('showtext', dependencies = TRUE)
library(showtext)

Import some Google Fonts

# https://fonts.google.com/featured/Superfamilies
font_add_google("Montserrat", "Montserrat")
font_add_google("Roboto", "Roboto")

Load font from the current search path into showtext

# Check the current search path for fonts
font_paths()    
#> [1] "C:\\Windows\\Fonts"

# List available font files in the search path
font_files()    
#>   [1] "AcadEref.ttf"                                
#>   [2] "AGENCYB.TTF"                           
#> [428] "pala.ttf"                                    
#> [429] "palab.ttf"                                   
#> [430] "palabi.ttf"                                  
#> [431] "palai.ttf"

# syntax: font_add(family = "<family_name>", regular = "/path/to/font/file")
font_add("Palatino", "pala.ttf")

font_families()
#> [1] "sans"         "serif"        "mono"         "wqy-microhei"

## Save to PNG 
ggsave("plot_showtext.png", plot = a, 
       type = 'cairo',

## Save to PDF
ggsave("plot_showtext.pdf", plot = a, 
       device = cairo_pdf,
       width = 6, height = 6, dpi = 150)  

## turn showtext off if no longer needed
showtext_auto(FALSE) 

Edit: another workaround to use showtext in RStudio. Run the following code at the beginning of the R session (source)

trace(grDevices::png, exit = quote({
    showtext::showtext_begin()
}), print = FALSE)

Edit 2: Starting from version 0.9, showtext can work well with the RStudio graphics device (RStudioGD). Simply call showtext_auto() in the RStudio session and then the plots will be displayed correctly.

I'm using laravel 7.x and this problem arose.. the following fixed it:

go to kernel.php and add these 2 classes to protected $middleware

\Illuminate\Session\Middleware\StartSession::class, \Illuminate\View\Middleware\ShareErrorsFromSession::class,

The simplicity is the power:

php artisan config:cache

You will receive:

Configuration cache cleared!

Configuration cached successfully!

It Doesn't work in Laravel 5.3+ if you want to try to access the value from the controller like below. It always returns null

<?php

    $value = env('MY_VALUE', 'default_value');

SOLUTION: Rather, you need to create a file in the configuration folder, say values.php and then write the code like below

File values.php

<?php

    return [

        'myvalue' => env('MY_VALUE',null),

        // Add other values as you wish

Then access the value in your controller with the following code

<?php

    $value = \Config::get('values.myvalue')

Where "values" is the filename followed by the key "myvalue".

I guess the only way to do this is by utilizing reusable fragments:

fragment UserFragment on Users {
    id
    username
    count
} 

FetchUsers {
    users(id: "2") {
        ...UserFragment
    }
}

If you still get this error when sending email: "Failed to authenticate on SMTP server with username "[email protected]" using 3 possible authenticators"

You may try one of these methods:

Go to https://accounts.google.com/UnlockCaptcha, click continue and unlock your account for access through other media/sites.

Use double quote for your password: like - "Abc@%$67eSDu"

Open the private channel, then:

• on web client:

  • look at the URL in your browser:
  • if it's for example https://web.telegram.org/#/im?p=c1192292378_2674311763110923980
  • then 1192292378 is the channel ID

• on mobile and desktop:

  • copy the link of any message of the channel:
  • if it's for example https://t.me/c/1192292378/31
  • then 1192292378 is the channel ID (bonus: 31 is the message ID)

• on Plus Messenger for Android:

  • open the infos of the channel:
  • the channel ID appears above, right under its name

WARNING be sure to add -100 prefix when using Telegram Bot API:

• if the channel ID is for example 1192292378
• then you should use -1001192292378

Also you can use default() filter. Or just a shortcut d()

Currently Spring Boot has the Actuator feature to get the logs of requests and responses.

But you can also get the logs using Aspect(AOP).

Aspect provides you with annotations like: @Before, @AfterReturning, @AfterThrowing etc.

@Before logs the request, @AfterReturning logs the response and @AfterThrowing logs the error message, You may not need all endpoints' log, so you can apply some filters on the packages.

Here are some examples:

For Request:

@Before("within(your.package.where.endpoints.are..*)")
    public void endpointBefore(JoinPoint p) {
        if (log.isTraceEnabled()) {
            log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " START");
            Object[] signatureArgs = p.getArgs();


            ObjectMapper mapper = new ObjectMapper();
            mapper.enable(SerializationFeature.INDENT_OUTPUT);
            try {

                if (signatureArgs[0] != null) {
                    log.trace("\nRequest object: \n" + mapper.writeValueAsString(signatureArgs[0]));
                }
            } catch (JsonProcessingException e) {
            }
        }
    }

Here @Before("within(your.package.where.endpoints.are..*)") has the package path. All endpoints within this package will generate the log.

For Response:

@AfterReturning(value = ("within(your.package.where.endpoints.are..*)"),
            returning = "returnValue")
    public void endpointAfterReturning(JoinPoint p, Object returnValue) {
        if (log.isTraceEnabled()) {
            ObjectMapper mapper = new ObjectMapper();

            log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " END");
        }
    }

Here @AfterReturning("within(your.package.where.endpoints.are..*)") has the package path. All endpoints within this package will generate the log. Also Object returnValue contains the response.

For Exception:

@AfterThrowing(pointcut = ("within(your.package.where.endpoints.are..*)"), throwing = "e")
public void endpointAfterThrowing(JoinPoint p, Exception e) throws DmoneyException {
    if (log.isTraceEnabled()) {
        System.out.println(e.getMessage());

        e.printStackTrace();


        log.error(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " " + e.getMessage());
    }
}

Here @AfterThrowing(pointcut = ("within(your.package.where.endpoints.are..*)"), throwing = "e") has the package path. All endpoints within this package will generate the log. Also Exception e contains the error response.

Here is the full code:

Graphviz is evidently included in Anaconda so as to be used with pydot or pydot-ng (both of which are included in Anaconda). You may want to consider using one of those instead of the 'graphviz' Python module.

Following these reccomended directions seemed to work:

Hint: Open the SDK manager by running: /path/to/android/tools/android

You will require: 1. "SDK Platform" for android-23 2. "Android SDK Platform-tools (latest) 3. "Android SDK Build-tools" (latest)

First, edit your .git/config and remove your username from 'url'.

I had this:

url = https://[email protected]/pathto/myrepo.git

And after modification:

url = https://bitbucket.org/pathto/myrepo.git

Then try to pull (or push) and use your email and password credentials to login.

I feel your frustration.

Android is crazy fragmented, and the the sheer amount of different examples on the web when searching is not helping.

That said, I just completed a sample partly based on mustafasevgi sample, partly built from several other stackoverflow answers, I try to achieve this functionality, in the most simplistic way possible, I feel this is close to the goal.

(Mind you, code should be easy to read and tweak, so it does not fit your json object perfectly, but should be super easy to edit, to fit any scenario)

protected class yourDataTask extends AsyncTask<Void, Void, JSONObject>
{
    @Override
    protected JSONObject doInBackground(Void... params)
    {

        String str="http://your.domain.here/yourSubMethod";
        URLConnection urlConn = null;
        BufferedReader bufferedReader = null;
        try
        {
            URL url = new URL(str);
            urlConn = url.openConnection();
            bufferedReader = new BufferedReader(new InputStreamReader(urlConn.getInputStream()));

            StringBuffer stringBuffer = new StringBuffer();
            String line;
            while ((line = bufferedReader.readLine()) != null)
            {
                stringBuffer.append(line);
            }

            return new JSONObject(stringBuffer.toString());
        }
        catch(Exception ex)
        {
            Log.e("App", "yourDataTask", ex);
            return null;
        }
        finally
        {
            if(bufferedReader != null)
            {
                try {
                    bufferedReader.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }

    @Override
    protected void onPostExecute(JSONObject response)
    {
        if(response != null)
        {
            try {
                Log.e("App", "Success: " + response.getString("yourJsonElement") );
            } catch (JSONException ex) {
                Log.e("App", "Failure", ex);
            }
        }
    }
}

This would be the json object it is targeted towards.

{
    "yourJsonElement":"Hi, I'm a string",
    "anotherElement":"Ohh, why didn't you pick me"
}

It is working on my end, hope this is helpful to someone else out there.

First go to the pip documentation if not install before: http://pip.readthedocs.org/en/stable/installing/

and follow the install pip which is first download get-pip.py from https://bootstrap.pypa.io/get-pip.py

Then run the following (which may require administrator access): python get-pip.py

You need to do something when it fails to handle the issue. Right now you are returning the actual exception. For example, if its not a problem that the user exists already and you want to use it as a get_or_create function maybe you handle the issue by returning the existing user object.

try:
    user = iam_conn.create_user(UserName=username)
    return user
except botocore.exceptions.ClientError as e:

    #this exception could actually be other things other than exists, so you want to evaluate it further in your real code.
    if e.message.startswith(
        'enough of the exception message to identify it as the one you want')

        print('that user already exists.')
        user = iam_conn.get_user(UserName=username)
        return user

    elif e.message.some_other_condition:

         #something else
    else:
         #unhandled ClientError
         raise(e)
except SomeOtherExceptionTypeYouCareAbout as e:
    #handle it

# any unhandled exception will raise here at this point.
# if you want a general handler

except Exception as e:
    #handle it.

That said, maybe it is a problem for your app, in which case you want to want to put the exception handler around the code that called your create user function and let the calling function determine how to deal with it, for example, by asking the user to input another username, or whatever makes sense for your application.

If you want to automate the steps, the suggestions here will work only to an extent.

I came across this tool called fetch and it worked quite fine for me. You can even specify the release. So, it takes a step to download and set it as executable, then fetch the required folder:

curl -sSLfo ./fetch \
https://github.com/gruntwork-io/fetch/releases/download/v0.3.12/fetch_linux_amd64

chmod +x ./fetch

./fetch --repo="https://github.com/foo/bar" --tag="${VERSION}" --source-path="/baz" /tmp/baz

I managed to fix it finally. The problem is not related to HikariCP. The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional or enveloping all the logic in a single call to transactional service method seem to solve the problem.

Just using the Array iteration methods built into JS is fine for this:

var result1 = [_x000D_
    {id:1, name:'Sandra', type:'user', username:'sandra'},_x000D_
    {id:2, name:'John', type:'admin', username:'johnny2'},_x000D_
    {id:3, name:'Peter', type:'user', username:'pete'},_x000D_
    {id:4, name:'Bobby', type:'user', username:'be_bob'}_x000D_
];_x000D_
_x000D_
var result2 = [_x000D_
    {id:2, name:'John', email:'[email protected]'},_x000D_
    {id:4, name:'Bobby', email:'[email protected]'}_x000D_
];_x000D_
_x000D_
var props = ['id', 'name'];_x000D_
_x000D_
var result = result1.filter(function(o1){_x000D_
    // filter out (!) items in result2_x000D_
    return !result2.some(function(o2){_x000D_
        return o1.id === o2.id;          // assumes unique id_x000D_
    });_x000D_
}).map(function(o){_x000D_
    // use reduce to make objects with only the required properties_x000D_
    // and map to apply this to the filtered array as a whole_x000D_
    return props.reduce(function(newo, name){_x000D_
        newo[name] = o[name];_x000D_
        return newo;_x000D_
    }, {});_x000D_
});_x000D_
_x000D_
document.body.innerHTML = '<pre>' + JSON.stringify(result, null, 4) +_x000D_
        '</pre>';

If you are doing this a lot, then by all means look at external libraries to help you out, but it's worth learning the basics first, and the basics will serve you well here.

User in the init of class:

constructor() {
    super()
    this.state = {
        email: ''
    }
}

Then in some function:

handleSome = () => { console.log(this.state.email) };

And in the input:

<TextInput onChangeText={(email) => this.setState({email})}/>

I had the same issue today recently installing VS2015 Community Edition Update 1.

I fixed the problem by just adding the "SQL Server Data Tools" from the VS2015 setup installer... When I ran the installer the first time I selected the "Custom" installation type instead of the "Default". I wanted to see what install options were available but not select anything different than what was already ticked. My assumption was that whatever was already ticked was essentially the default install. But its not.

Enable TLs 1.2 from IE and add the following

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

This is caused by non-matching Spring Boot dependencies. Check your classpath to find the offending resources. You have explicitly included version 1.1.8.RELEASE, but you have also included 3 other projects. Those likely contain different Spring Boot versions, leading to this error.

In my case I had to set the

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=465           <<<<<<<------------------------- (FOCUS THIS)
MAIL_USERNAME=<<your email address>>
MAIL_PASSWORD=<<app password>>

MAIL_ENCRYPTION= ssl    <<<<<<<------------------------- (FOCUS THIS)

to work it.. Might be useful. Rest of the code was same as @Sid said.

And I think that editing both environment file and app/config/mail.php is unnecessary. Just use one method.

Edit as per the comment by @Zan

If you need to enable tls protection use following settings.

MAIL_PORT=587
MAIL_ENCRYPTION= tls  

See here for some other gmail settings

Echoing Data If It Exists

Sometimes you may wish to echo a variable, but you aren't sure if the variable has been set. We can express this in verbose PHP code like so:

{{ isset($name) ? $name : 'Default' }}

However, instead of writing a ternary statement, Blade provides you with the following convenient short-cut:

{{ $name or 'Default' }}

In this example, if the $name variable exists, its value will be displayed. However, if it does not exist, the word Default will be displayed.

From https://laravel.com/docs/5.4/blade#displaying-data

** Update ** A scalars converter has been added to retrofit that allows for a String response with less ceremony than my original answer below.

Example interface --

public interface GitHubService {
    @GET("/users/{user}")
    Call<String> listRepos(@Path("user") String user);
}

Add the ScalarsConverterFactory to your retrofit builder. Note: If using ScalarsConverterFactory and another factory, add the scalars factory first.

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(ScalarsConverterFactory.create())
    // add other factories here, if needed.
    .build();

You will also need to include the scalars converter in your gradle file --

implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'

--- Original Answer (still works, just more code) ---

I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject land. I suspect your specific problem might be better solved using a custom gson TypeAdapter or a retrofit Converter if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -

First, if you are using Retrofit 2, you should start using the Call API. Instead of sending an object to convert as the type parameter, use ResponseBody from okhttp --

public interface GitHubService {
    @GET("/users/{user}")
    Call<ResponseBody> listRepos(@Path("user") String user);
}

then you can create and execute your call --

GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Response<ResponseBody> response) {
        try {
            System.out.println(response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Throwable t) {
        e.printStackTrace();
    }
});

Note The code above calls string() on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream() instead. See the ResponseBody docs.

your MAIL_PASSWORD=must a APPpasword after change the .env stop the server then clear configuratios cahce php artisan config:cahce and start the server again

Perform a composer update, then composer dump-autoload.

If the above doesn't solve the problem, change the classmap in your composer.json file such that it contains the project-relative path to your php files:

"autoload-dev": {
    "classmap": [
        "tests/TestCase.php",
        "database/seeds/UserTableSeeder.php" //include the file with its path here
    ]
}, /** ... */

and soon after, perform a composer dump-autoload, and it should work now like a breeze!

Edit by @JMSamudio

If composer dump-autoload is not found, just enable this option composer config -g -- disable-tls true.

cd /etc/postgresql/9.x/main/

open file named postgresql.conf

sudo vi postgresql.conf

add this line to that file

listen_addresses = '*'

then open file named pg_hba.conf

sudo vi pg_hba.conf

and add this line to that file

host  all  all 0.0.0.0/0 md5

It allows access to all databases for all users with an encrypted password

restart your server

sudo /etc/init.d/postgresql restart

This is what worked for me.

            .allowedHeaders("*")
            .allowedOrigins("*")
            .allowCredentials(true);
    }

}

I got the same error when I executed the Spring JPA deleteAll() method from Junit test cases. I simply used the deleteInBatch() & deleteAllInBatch() and its perfectly works. We do not need to mark @Transactional at the test cases level.

There are instructions on how to install sshpass here:

https://gist.github.com/arunoda/7790979

For Mac you will need to install xcode and command line tools then use the unofficial Homewbrew command:

brew install https://raw.githubusercontent.com/kadwanev/bigboybrew/master/Library/Formula/sshpass.rb

If you just want go get to work real fast, and move along with your work...

Just export GIT_TERMINAL_PROMPT=1

$ export GIT_TERMINAL_PROMPT=1
$ go get [whatever]

It will now prompt you for a user/pass for the rest of your shell session. Put this in your .profile or setup git as above for a more permanent solution.

Try to execute below command in your terminal :

mysql -h localhost -P 3306 -u root -p

If you successfully connect to your database, then same thing has to happen with Mysql Workbench.

If you are unable to connect then I think 3306 port is acquired by another process.

Find which process running on 3306 port. If required, give admin privileges using sudo.

netstat -lnp | grep 3306

Kill/stop that process and restart your MySQL server. You are good to go.

Execute below command to find my.cnf file in macbook.

mysql --help | grep cnf

You can change MySQL port to any available port in your system. But after that, make sure you restart MySQL server.

You can use a session object. It stores the cookies so you can make requests, and it handles the cookies for you

s = requests.Session() 
# all cookies received will be stored in the session object

s.post('http://www...',data=payload)
s.get('http://www...')

Docs: https://requests.readthedocs.io/en/master/user/advanced/#session-objects

You can also save the cookie data to an external file, and then reload them to keep session persistent without having to login every time you run the script:

I had a similar issue when using AD on CAS , i.e. 52e error, In my case application accepts the Full Name when in the form of CN= instead of the actual username.

For example, if you had a user who's full name is Ross Butler and their login username is rbutler --you would normally put something like, cn=rbutler,ou=Users,dc=domain,dc=com but ours failed everytime. By changing this to cn=Ross Butler,ou=Users,dc=domain,dc=com it passed!!

    "registetedDate": "2015-4-3",
    "firstname": "hesh",
    "contactNo": "07762",
    "accountNo": "16161",
    "lastName": "jay"
    "arrayOneName" : [
        {
            "Id" : 1,
            "Employee" : "EmpOne", 
            "Deptartment" : "HR"
        },
        {
            "Id" : 2,
            "Employee" : "EmpTwo",
            "Deptartment" : "IT"
        },
        {
            "Id" : 3,
            "Employee" : "EmpThree",
            "Deptartment" : "Sales"
        }
    ],
    "arrayTwoName": [
        {
            "Product": "3",
            "Price": "6790"
        }
    ],
    "arrayThreeName" : [
        "name1", "name2", "name3", "name4" // For Strings
    ],
    "arrayFourName" : [
        1, 2, 3, 4 // For Numbers
    ]

}

Remember to use this in POST with proper endpoint. Also, RAW selected and JSON(application/json) in Body Tab.

Like THIS:

Update 1:

I don't think multiple @RequestBody is allowed or possible.

@RequestBody parameter must have the entire body of the request and bind that to only one object.

You have to use something like Wrapper Object for this to work.

It generally comes to mind that you have set up two-factor authentication, after a few password trials and maybe a password reset. So, how can we git clone a private repository using two-factor authentication? It is simple, using access tokens.

How to Authenticate Git using Access Tokens

1. Go to https://github.com/settings/tokens
2. Click Generate New Token button on top right.
3. Give your token a descriptive name.
4. Set all required permissions for the token.
5. Click Generate token button at the bottom.
6. Copy the generated token to a safe place.
7. Use this token instead of password when you use git clone.

Wow, it works!

The git blame command is used to examine the contents of a file line by line and see when each line was last modified and who the author of the modifications was.

If there was a bug in code,use it to identify who cased it,then you can blame him. Git blame is get blame(d).

If you need to know history of one line code,use git log -S"code here", simpler than git blame.

Check Following Things

• Make Sure You Have MySQL Server Running
• Check connection with default credentials i.e. username : 'root' & password : '' [Blank Password]
• Try login phpmyadmin with same credentials
• Try to put 127.0.0.1 instead localhost or your lan IP would do too.
• Make sure you are running MySql on 3306 and if you have configured make sure to state it while making a connection

You should find installed packages in :

anaconda's directory / lib / site_packages

That's where i found mine.

put this line in parent construct : $this->load->database();

function  __construct() {
    parent::__construct();
    $this->load->library('lib_name');
    $model=array('model_name');
    $this->load->model($model);
    $this->load->database();
}

this way.. it should work..

I know you have already accepted another answer, but I think the broader issue needs to addressed - programming style that is suitable to the current language.

Yes, 'initialization' isn't needed in Python, but what you are doing isn't initialization. It is just an incomplete and erroneous imitation of initialization as practiced in other languages. The important thing about initialization in static typed languages is that you specify the nature of the variables.

In Python, as in other languages, you do need to give variables values before you use them. But giving them values at the start of the function isn't important, and even wrong if the values you give have nothing to do with values they receive later. That isn't 'initialization', it's 'reuse'.

I'll make some notes and corrections to your code:

def main():
   # doc to define the function
   # proper Python indentation
   # document significant variables, especially inputs and outputs
   # grade_1, grade_2, grade_3, average - id these
   # year - id this
   # fName, lName, ID, converted_ID 

   infile = open("studentinfo.txt", "r") 
   # you didn't 'intialize' this variable

   data = infile.read()  
   # nor this  

   fName, lName, ID, year = data.split(",")
   # this will produce an error if the file does not have the right number of strings
   # 'year' is now a string, even though you 'initialized' it as 0

   year = int(year)
   # now 'year' is an integer
   # a language that requires initialization would have raised an error
   # over this switch in type of this variable.

   # Prompt the user for three test scores
   grades = eval(input("Enter the three test scores separated by a comma: "))
   # 'eval' ouch!
   # you could have handled the input just like you did the file input.

   grade_1, grade_2, grade_3 = grades   
   # this would work only if the user gave you an 'iterable' with 3 values
   # eval() doesn't ensure that it is an iterable
   # and it does not ensure that the values are numbers. 
   # What would happen with this user input: "'one','two','three',4"?

   # Create a username 
   uName = (lName[:4] + fName[:2] + str(year)).lower()

   converted_id = ID[:3] + "-" + ID[3:5] + "-" + ID[5:]
   # earlier you 'initialized' converted_ID
   # initialization in a static typed language would have caught this typo
   # pseudo-initialization in Python does not catch typos
   ....

Assuming you're using Spring Boot, another option is to put the following in your application.properties:

logging.level.org.springframework.security=DEBUG

This is the same for most other Spring modules as well.

If you're not using Spring Boot, try setting the property in your logging configuration, e.g. logback.

Here is the application.yml version as well:

logging:
  level:
    org:
      springframework:
        security: DEBUG

Simply put, it provides a way to validate fields prior to execution. This is a good programming style as it enhances readability. In other languages, it may look like this:

func doSomething() {
    if something == nil {
        // return, break, throw error, etc.
    }
    ...
}

But because Swift provides you with optionals, we can't check if it's nil and assign its value to a variable. In contrast, if let checks that it's not nil and assigns a variable to hold the actual value. This is where guard comes into play. It gives you a more concise way of exiting early using optionals.

Make sure the scp command is available on both sides - both on the client and on the server.

BOTH Server and Client, otherwise you will encounter this kind of (weird)error message on your client: scp: command not found or something similar even though though you have it all configured locally.

For get response in JSON format :

  1.$response = (string) $res->getBody();
      $response =json_decode($response); // Using this you can access any key like below
     
     $key_value = $response->key_name; //access key  

  2. $response = json_decode($res->getBody(),true);
     
     $key_value =   $response['key_name'];//access key

It seems the button you are invoking is not in the layout you are using in setContentView(R.layout.your_layout) Check it.

in laravel 5 first we need to create migration and then run the migration

Step 1.

php artisan make:migration create_users_table --create=users

Step 2.

php artisan migrate

When using permitAll it means every authenticated user, however you disabled anonymous access so that won't work.

What you want is to ignore certain URLs for this override the configure method that takes WebSecurity object and ignore the pattern.

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/api/v1/signup");
}

And remove that line from the HttpSecurity part. This will tell Spring Security to ignore this URL and don't apply any filters to them.

I also had to setup connection to 2 datasources from Spring Boot application, and it was not easy - the solution mentioned in the Spring Boot documentation didn't work. After a long digging through the internet I made it work and the main idea was taken from this article and bunch of other places.

The following solution is written in Kotlin and works with Spring Boot 2.1.3 and Hibernate Core 5.3.7. Main issue was that it was not enough just to setup different DataSource configs, but it was also necessary to configure EntityManagerFactory and TransactionManager for both databases.

Here is config for the first (Primary) database:

@Configuration
@EnableJpaRepositories(
    entityManagerFactoryRef = "firstDbEntityManagerFactory",
    transactionManagerRef = "firstDbTransactionManager",
    basePackages = ["org.path.to.firstDb.domain"]
)
@EnableTransactionManagement
class FirstDbConfig {

    @Bean
    @Primary
    @ConfigurationProperties(prefix = "spring.datasource.firstDb")
    fun firstDbDataSource(): DataSource {
        return DataSourceBuilder.create().build()
    }

    @Primary
    @Bean(name = ["firstDbEntityManagerFactory"])
    fun firstDbEntityManagerFactory(
        builder: EntityManagerFactoryBuilder,
        @Qualifier("firstDbDataSource") dataSource: DataSource
    ): LocalContainerEntityManagerFactoryBean {
        return builder
            .dataSource(dataSource)
            .packages(SomeEntity::class.java)
            .persistenceUnit("firstDb")
            // Following is the optional configuration for naming strategy
            .properties(
                singletonMap(
                    "hibernate.naming.physical-strategy",
                    "org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl"
                )
            )
            .build()
    }

    @Primary
    @Bean(name = ["firstDbTransactionManager"])
    fun firstDbTransactionManager(
        @Qualifier("firstDbEntityManagerFactory") firstDbEntityManagerFactory: EntityManagerFactory
    ): PlatformTransactionManager {
        return JpaTransactionManager(firstDbEntityManagerFactory)
    }
}

And this is config for second database:

@Configuration
@EnableJpaRepositories(
    entityManagerFactoryRef = "secondDbEntityManagerFactory",
    transactionManagerRef = "secondDbTransactionManager",
    basePackages = ["org.path.to.secondDb.domain"]
)
@EnableTransactionManagement
class SecondDbConfig {

    @Bean
    @ConfigurationProperties("spring.datasource.secondDb")
    fun secondDbDataSource(): DataSource {
        return DataSourceBuilder.create().build()
    }

    @Bean(name = ["secondDbEntityManagerFactory"])
    fun secondDbEntityManagerFactory(
        builder: EntityManagerFactoryBuilder,
        @Qualifier("secondDbDataSource") dataSource: DataSource
    ): LocalContainerEntityManagerFactoryBean {
        return builder
            .dataSource(dataSource)
            .packages(EntityFromSecondDb::class.java)
            .persistenceUnit("secondDb")
            .build()
    }

    @Bean(name = ["secondDbTransactionManager"])
    fun secondDbTransactionManager(
        @Qualifier("secondDbEntityManagerFactory") secondDbEntityManagerFactory: EntityManagerFactory
    ): PlatformTransactionManager {
        return JpaTransactionManager(secondDbEntityManagerFactory)
    }
}

The properties for datasources are like this:

spring.datasource.firstDb.jdbc-url=
spring.datasource.firstDb.username=
spring.datasource.firstDb.password=

spring.datasource.secondDb.jdbc-url=
spring.datasource.secondDb.username=
spring.datasource.secondDb.password=

Issue with properties was that I had to define jdbc-url instead of url because otherwise I had an exception.

p.s. Also you might have different naming schemes in your databases, which was the case for me. Since Hibernate 5 does not support all previous naming schemes, I had to use solution from this answer - maybe it will also help someone as well.

If you are using Windows,

1. make a folder and open git bash from there

2. in the git bash,

   git clone [email protected]:Example/projectName.git

I'm using Laravel with Docker. I solved this problem by changing the value of DB_HOST from localhost to mysql.

DB_HOST=mysql

I has similar problem in context of Stripe:

Error: Stripe no longer supports API requests made with TLS 1.0. Please initiate HTTPS connections with TLS 1.2 or later. You can learn more about this at https://stripe.com/blog/upgrading-tls.

Forcing TLS 1.2 using CURL parameter is temporary solution or even it can't be applied because of lack of room to place an update. By default TLS test function https://gist.github.com/olivierbellone/9f93efe9bd68de33e9b3a3afbd3835cf showed following configuration:

SSL version: NSS/3.21 Basic ECC
SSL version number: 0
OPENSSL_VERSION_NUMBER: 1000105f
TLS test (default): TLS 1.0
TLS test (TLS_v1): TLS 1.2
TLS test (TLS_v1_2): TLS 1.2

I updated libraries using following command:

yum update nss curl openssl

and then saw this:

SSL version: NSS/3.21 Basic ECC
SSL version number: 0
OPENSSL_VERSION_NUMBER: 1000105f
TLS test (default): TLS 1.2
TLS test (TLS_v1): TLS 1.2
TLS test (TLS_v1_2): TLS 1.2

Please notice that default TLS version changed to 1.2! That globally solved problem. This will help PayPal users too: https://www.paypal.com/au/webapps/mpp/tls-http-upgrade (update before end of June 2017)

public class B3PassingExcelDataBase {


    @Test()
    //Import the data::row start at 3 and column at 1: 
    public static void imortingData () throws IOException {

        FileInputStream  file=new         FileInputStream("/Users/Downloads/Book2.xlsx");
        XSSFWorkbook book=new XSSFWorkbook(file);
        XSSFSheet sheet=book.getSheet("Sheet1");

        int rowNum=sheet.getLastRowNum();
        System.out.println(rowNum);

        //get the row and value and assigned to variable to use in application
        for (int r=3;r<rowNum;r++) {

            // Rows stays same but column num changes and this is for only one person. It iterate for other.
             XSSFRow currentRow=sheet.getRow(r);

             String fName=currentRow.getCell(1).toString();
             String lName=currentRow.getCell(2).toString();
             String phone=currentRow.getCell(3).toString();
             String email=currentRow.getCell(4).toString()

               //passing the data
                yogen.findElement(By.name("firstName")).sendKeys(fName);    ;
                yogen.findElement(By.name("lastName")).sendKeys(lName); ;
                yogen.findElement(By.name("phone")).sendKeys(phone);    ;

        }

        yogen.close();


    }

}

This works for stdout too:

spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.use_sql_comments=true
spring.jpa.properties.hibernate.format_sql=true

To log values:

logging.level.org.hibernate.type=trace

Just add this to application.properties.

Try:

git config --global credential.helper cache

This command prevents git to ask username and password, not forever but with a default limit to 15 minutes.

git config --global credential.helper 'cache --timeout=3600'

This moves the default limit to 1 hour.

add below snipped in your bash profile -

PATH="/Library/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
code () { VSCODE_CWD="$PWD" open -n -b "com.microsoft.VSCode" --args $* ;}

I would like share an example to understand the usage of stream().filter

Code Snippet: Sample program to identify even number.

import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;

public void fetchEvenNumber(){
        List<Integer> numberList = new ArrayList<>();
        numberList.add(10);
        numberList.add(11);
        numberList.add(12);
        numberList.add(13);
        numberList.add(14);
        numberList.add(15);

        List<Integer> evenNumberListObj = numberList.stream().filter(i -> i%2 == 0).collect(Collectors.toList());
        System.out.println(evenNumberListObj);
}

Output will be : [10, 12, 14]

List evenNumberListObj = numberList.stream().filter(i -> i%2 == 0).collect(Collectors.toList());

numberList: it is an ArrayList object contains list of numbers.

java.util.Collection.stream() : stream() will get the stream of collection, which will return the Stream of Integer.

filter: Returns a stream that match the given predicate. i.e based on given condition (i -> i%2 != 0) returns the matching stream.

collect: whatever the stream of Integer filter based in the filter condition, those integer will be put in a list.

Questions 1 & 2

So basically, first parameter is the object to iterate on. It can be an array or an object. If it is an object like this :

var values = {name: 'misko', gender: 'male'};

Angular will take each value one by one the first one is name, the second is gender.

If your object to iterate on is an array (also possible), like this :

[{ "Name" : "Thomas", "Password" : "thomasTheKing" },
 { "Name" : "Linda", "Password" : "lindatheQueen" }]

Angular.forEach will take one by one starting by the first object, then the second object.

For each of this object, it will so take them one by one and execute a specific code for each value. This code is called the iterator function. forEach is smart and behave differently if you are using an array of a collection. Here is some exemple :

var obj = {name: 'misko', gender: 'male'};
var log = [];
angular.forEach(obj, function(value, key) {
  console.log(key + ': ' + value);
});
// it will log two iteration like this
// name: misko
// gender: male

So key is the string value of your key and value is ... the value. You can use the key to access your value like this : obj['name'] = 'John'

If this time you display an array, like this :

var values = [{ "Name" : "Thomas", "Password" : "thomasTheKing" },
           { "Name" : "Linda", "Password" : "lindatheQueen" }];
angular.forEach(values, function(value, key){
     console.log(key + ': ' + value);
});
// it will log two iteration like this
// 0: [object Object]
// 1: [object Object]

So then value is your object (collection), and key is the index of your array since :

[{ "Name" : "Thomas", "Password" : "thomasTheKing" },
 { "Name" : "Linda", "Password" : "lindatheQueen" }]
// is equal to
{0: { "Name" : "Thomas", "Password" : "thomasTheKing" },
 1: { "Name" : "Linda", "Password" : "lindatheQueen" }}

I hope it answer your question. Here is a JSFiddle to run some code and test if you want : http://jsfiddle.net/ygahqdge/

Debugging your code

The problem seems to come from the fact $http.get() is an asynchronous request.

You send a query on your son, THEN when you browser end downloading it it execute success. BUT just after sending your request your perform a loop using angular.forEach without waiting the answer of your JSON.

You need to include the loop in the success function

var app = angular.module('testModule', [])
    .controller('testController', ['$scope', '$http', function($scope, $http){
    $http.get('Data/info.json').then(function(data){
         $scope.data = data;

         angular.forEach($scope.data, function(value, key){
         if(value.Password == "thomasTheKing")
           console.log("username is thomas");
         });
    });

});

This should work.

Going more deeply

The $http API is based on the deferred/promise APIs exposed by the $q service. While for simple usage patterns this doesn't matter much, for advanced usage it is important to familiarize yourself with these APIs and the guarantees they provide.

You can give a look at deferred/promise APIs, it is an important concept of Angular to make smooth asynchronous actions.

It is possible but, before git 2.9.3 (august 2016), a git push would print the full url used when pushing back to the cloned repo.
That would include your username and password!

But no more: See commit 68f3c07 (20 Jul 2016), and commit 882d49c (14 Jul 2016) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 71076e1, 08 Aug 2016)}

push: anonymize URL in status output

Commit 47abd85 (fetch: Strip usernames from url's before storing them, 2009-04-17, Git 1.6.4) taught fetch to anonymize URLs.
The primary purpose there was to avoid sticking passwords in merge-commit messages, but as a side effect, we also avoid printing them to stderr.

The push side does not have the merge-commit problem, but it probably should avoid printing them to stderr. We can reuse the same anonymizing function.

Note that for this to come up, the credentials would have to appear either on the command line or in a git config file, neither of which is particularly secure.
So people should be switching to using credential helpers instead, which makes this problem go away.

But that's no excuse not to improve the situation for people who for whatever reason end up using credentials embedded in the URL.

After change .env with the new configuration, you have to stop the server and run it again (php artisan serve). Cause laravel gets the environment when it's initialized the server. If you don't restart, you will change the .env asking yourself why the changes aren't taking place!!

Well, you're getting a java.lang.NoClassDefFoundError. In your pom.xml, hibernate-core version is 3.3.2.GA and declared after hibernate-entitymanager, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final from hibernate-entitymanager.

You're using spring-boot as parent, so no need to declare version of some dependencies, since they are managed by spring-boot.

Also, hibernate-commons-annotations is inherited from hibernate-entitymanager and hibernate-annotations is an old version of hibernate-commons-annotations, you can remove both.

Finally, your pom.xml can look like this:

Let me know if you have a problem.

Using MAMP ON Mac, I solve my problem by renaming

/Applications/MAMP/tmp/mysql/mysql.sock.lock

to

/Applications/MAMP/tmp/mysql/mysql.sock

None of these worked for me when I deployed my website online on shared hosting, below is what I did that worked.

In the .env file, I changed

DB_HOST=127.0.0.1

to

DB_HOST=localhost

and viola, it worked well as expected.

try to add this in your payload

grant_type=password&username=pippo&password=pluto

I couldn't find a direct GDrive/DropBox solution. I'm also surprised there's no lazy solution for a free ftp host. Windows azure offers a ftp server "FTP connector" that's fairly easy to turn on at: https://portal.azure.com

You can get a free 1 GB account by selecting "View All" machine types during your deployment.

That problem happens sometimes due to wrong password. Please check if you are linked with AD password (Active Directory Password) and you recently changed you AD password but still trying git command with old password or not.

Update old AD password

Control Panel > Credential Manager > Windows Credential > change github password with my new AD password

You are scanning the wrong package:

@ComponentScan("**org**.pharmacy")

Where as it should be:

@ComponentScan("**com**.pharmacy")

Since your package names start with com and not org.

Try:

$articles = DB::table('articles')
            ->select('articles.id as articles_id', ..... )
            ->join('categories', 'articles.categories_id', '=', 'categories.id')
            ->join('users', 'articles.user_id', '=', 'user.id')

            ->get();

My opinion after making changes on your .env files restart your server and serve the app again. Just to be sure of the actual error. The php artisan clear and cache afterwards works pretty fine.

In PHPMyAdmin, Ignore / leave the size value empty on the pop-up window.

All of these answers are turned off the logging at creation time.

But what if we need to turn off the logging on runtime ?

By runtime i mean after initializing the sequelize object using new Sequelize(.. function.

I peeked into the github source, found a way to turn off logging in runtime.

// Somewhere your code, turn off the logging
sequelize.options.logging = false

// Somewhere your code, turn on the logging
sequelize.options.logging = true 

After many tries I found that you should use createNativeQuery And you can send parameters using # replacement

In my example

String UPDATE_lOGIN_TABLE_QUERY = "UPDATE OMFX.USER_LOGIN SET LOGOUT_TIME = SYSDATE WHERE LOGIN_ID = #loginId AND USER_ID = #userId";


Query query = em.createNativeQuery(logQuery);

            query.setParameter("userId", logDataDto.getUserId());
            query.setParameter("loginId", logDataDto.getLoginId());

            query.executeUpdate();

You can use DataSourceBuilder if you are using jdbc starter. Also, in order to override the default autoconfiguration bean you need to mark your bean as a @Primary

In my case I have properties starting with datasource.postgres prefix.

E.g

@ConfigurationProperties(prefix = "datasource.postgres")
@Bean
@Primary
public DataSource dataSource() {
    return DataSourceBuilder
        .create()
        .build();
}

If it is not feasible for you, then you can use

@Bean
@Primary
public DataSource dataSource() {
    return DataSourceBuilder
        .create()
        .username("")
        .password("")
        .url("")
        .driverClassName("")
        .build();
}

Add produces = "application/json" in @RequestMapping

By Changing The DbContext As Below;

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
        modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>();
    }

Just adding in OnModelCreating method call to base.OnModelCreating(modelBuilder); and it becomes fine. I am using EF6.

In my humble opinion, idempotence means:

• PUT:

I send a compete resource definition, so - the resulting resource state is exactly as defined by PUT params. Each and every time I update the resource with the same PUT params - the resulting state is exactly the same.

• PATCH:

I sent only part of the resource definition, so it might happen other users are updating this resource's OTHER parameters in a meantime. Consequently - consecutive patches with the same parameters and their values might result with different resource state. For instance:

Presume an object defined as follows:

CAR: - color: black, - type: sedan, - seats: 5

I patch it with:

{color: 'red'}

The resulting object is:

CAR: - color: red, - type: sedan, - seats: 5

Then, some other users patches this car with:

{type: 'hatchback'}

so, the resulting object is:

CAR: - color: red, - type: hatchback, - seats: 5

Now, if I patch this object again with:

{color: 'red'}

the resulting object is:

CAR: - color: red, - type: hatchback, - seats: 5

What is DIFFERENT to what I've got previously!

This is why PATCH is not idempotent while PUT is idempotent.

Just in case you are interested in a SwiftUI solution, this it's working for me:

 TextField("write your answer here...",
            text: Binding(
                     get: {
                        return self.query
                       },
                     set: { (newValue) in
                        self.fetch(query: newValue) // any action you need
                                return self.query = newValue
                      }
            )
  )

I have to say it's not my idea, I read it in this blog: SwiftUI binding: A very simple trick

I was recently looking for a nice solution to this without adding React-Bootstrap to my project (as Bootstrap 4 is about to be released).

This is my solution: https://jsfiddle.net/16j1se1q/1/

let Modal = React.createClass({
    componentDidMount(){
        $(this.getDOMNode()).modal('show');
        $(this.getDOMNode()).on('hidden.bs.modal', this.props.handleHideModal);
    },
    render(){
        return (
          <div className="modal fade">
            <div className="modal-dialog">
              <div className="modal-content">
                <div className="modal-header">
                  <button type="button" className="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                  <h4 className="modal-title">Modal title</h4>
                </div>
                <div className="modal-body">
                  <p>One fine body&hellip;</p>
                </div>
                <div className="modal-footer">
                  <button type="button" className="btn btn-default" data-dismiss="modal">Close</button>
                  <button type="button" className="btn btn-primary">Save changes</button>
                </div>
              </div>
            </div>
          </div>
        )
    },
    propTypes:{
        handleHideModal: React.PropTypes.func.isRequired
    }
});



let App = React.createClass({
    getInitialState(){
        return {view: {showModal: false}}
    },
    handleHideModal(){
        this.setState({view: {showModal: false}})
    },
    handleShowModal(){
        this.setState({view: {showModal: true}})
    },
    render(){
    return(
        <div className="row">
            <button className="btn btn-default btn-block" onClick={this.handleShowModal}>Open Modal</button>
            {this.state.view.showModal ? <Modal handleHideModal={this.handleHideModal}/> : null}
        </div>
    );
  }
});

React.render(
   <App />,
    document.getElementById('container')
);

The main idea is to only render the Modal component into the React DOM when it is to be shown (in the App components render function). I keep some 'view' state that indicates whether the Modal is currently shown or not.

The 'componentDidMount' and 'componentWillUnmount' callbacks either hide or show the modal (once it is rendered into the React DOM) via Bootstrap javascript functions.

I think this solution nicely follows the React ethos but suggestions are welcome!

I found a pretty simple way to handle "one copy of script per system". It doesn't allow me to run multiple copies of the script from many accounts though (on standard Linux that is).

Solution:

At the beginning of script, I gave:

pidof -s -o '%PPID' -x $( basename $0 ) > /dev/null 2>&1 && exit

Apparently pidof works great in a way that:

• it doesn't have limit on program name like ps -C ...
• it doesn't require me to do grep -v grep ( or anything similar )

And it doesn't rely on lockfiles, which for me is a big win, because relaying on them means you have to add handling of stale lockfiles - which is not really complicated, but if it can be avoided - why not?

As for checking with "one copy of script per running user", i wrote this, but I'm not overly happy with it:

(
    pidof -s -o '%PPID' -x $( basename $0 ) | tr ' ' '\n'
    ps xo pid= | tr -cd '[0-9\n]'
) | sort | uniq -d

and then I check its output - if it's empty - there are no copies of the script from same user.

@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET /a pid=1600
FOR /f "skip=3delims=" %%a IN ('tasklist') DO (
 SET "found=%%a"
 SET /a foundpid=!found:~26,8!
 IF %pid%==!foundpid! echo found %pid%=!found:~0,24%!
)

GOTO :EOF

...set PID to suit your circumstance.

Try this, replacing .myClassName with the actual name of the class (but keep the period at the beginning).

$('.myClassName').each(function() {
    alert( this.id );
});

So if the class is "test", you'd do $('.test').each(func....

This is the specific form of .each() that iterates over a jQuery object.

The form you were using iterates over any type of collection. So you were essentially iterating over an array of characters t,e,s,t.

Using that form of $.each(), you would need to do it like this:

$.each($('.myClassName'), function() {
    alert( this.id );
});

...which will have the same result as the example above.

WORKING ALWAYS ON TOP IMAGE BUTTON

first of all sorry for my english

i edit your codes and make working image button that listens his touch event do not give touch control to his background elements.

also it gives touch listeners to out of other elements

button alingments are bottom and left

you can chage alingments but you need to chages cordinats in touch event in the if element

.Text is the formatted cell's displayed value; .Value is the value of the cell possibly augmented with date or currency indicators; .Value2 is the raw underlying value stripped of any extraneous information.

range("A1") = Date
range("A1").numberformat = "yyyy-mm-dd"
debug.print range("A1").text
debug.print range("A1").value
debug.print range("A1").value2

'results from Immediate window
2018-06-14
6/14/2018 
43265 

range("A1") = "abc"
range("A1").numberformat = "_(_(_(@"
debug.print range("A1").text
debug.print range("A1").value
debug.print range("A1").value2

'results from Immediate window
   abc
abc
abc

range("A1") = 12
range("A1").numberformat = "0 \m\m"
debug.print range("A1").text
debug.print range("A1").value
debug.print range("A1").value2

'results from Immediate window
12 mm
12
12

If you are processing the cell's value then reading the raw .Value2 is marginally faster than .Value or .Text. If you are locating errors then .Text will return something like #N/A as text and can be compared to a string while .Value and .Value2 will choke comparing their returned value to a string. If you have some custom cell formatting applied to your data then .Text may be the better choice when building a report.

You want to git rebase -i to perform an interactive rebase.

If you're currently on your "commit 1", and the commit you want to merge, "commit 2", is the previous commit, you can run git rebase -i HEAD~2, which will spawn an editor listing all the commits the rebase will traverse. You should see two lines starting with "pick". To proceed with squashing, change the first word of the second line from "pick" to "squash". Then save your file, and quit. Git will squash your first commit into your second last commit.

Note that this process rewrites the history of your branch. If you are pushing your code somewhere, you'll have to git push -f and anybody sharing your code will have to jump through some hoops to pull your changes.

Note that if the two commits in question aren't the last two commits on the branch, the process will be slightly different.

You could actually just set the image of the UIButton to what you would normally put in a UIImageView. For example, where you would do:

myImageView.image = myUIImage

You could instead use:

myButton.setImage(myUIImage, forState: UIControlState.Normal)

So, here's what your code could look like:

override func viewDidLoad(){
  super.viewDidLoad()

  var myUIImage: UIImage //set the UIImage here
  myButton.setImage(myUIImage, forState: UIControlState.Normal)
}

@IBOutlet var myButton: UIButton!
@IBAction func buttonTap(sender: UIButton!){
  //handle the image tap
}

The great thing about using this method is that if you have to load the image from a database, you could set the title of the button before you set the image:

myButton.setTitle("Loading Image...", forState: UIControlState.Normal)

To tell your users that you are loading the image

Somewhere, you need to tell Apache that people are allowed to see contents of this directory.

<Directory "F:/bar/public">
    Order Allow,Deny
    Allow from All
    # Any other directory-specific stuff
</Directory>

('long text to be truncated').replace(/(.{250})..+/, "$1…");

Somehow above code was not working for some kind of copy pasted or written text in vuejs app. So I used lodash truncate and its now working fine.

_.truncate('long text to be truncated', { 'length': 250, 'separator': ' '});

Didnt work for me.

I created a new key and string value and managed to get it working

Using Django 3.1.1 and all solutions I tried failed. However, adding the "csrfmiddlewaretoken" key to my POST body worked. Here's the call I made:

$.post(url, {
  csrfmiddlewaretoken: window.CSRF_TOKEN,
  method: "POST",
  data: JSON.stringify(data),
  dataType: 'JSON',
});

And in the HTML template:

<script type="text/javascript">

Wanna a list of folder in xampp?

Just delete or change the file index.php to index.txt. And you will get the list just typing url: localhost.

Jenkins Pipeline also provides the current build number as the property number of the currentBuild. It can be read as currentBuild.number.

For example:

// Scripted pipeline
def buildNumber = currentBuild.number

// Declarative pipeline
echo "Build number is ${currentBuild.number}"

Other properties of currentBuild are described in the Pipeline Syntax: Global Variables page that is included on each Pipeline job page. That page describes the global variables available in the Jenkins instance based on the current plugins.

No it is not possible to override a constructor. If we try to do this then compiler error will come. And it is never possible in Java. Lets see the example. It will ask please write a return type o the method. means it will treat that overriden constructor as a method not as a constructor.

package com.sample.test;

class Animal{

    public static void showMessage()
    {
        System.out.println("we are in Animal class");
    }
}

class Dog extends Animal{

    public void DogShow() 
    {
        System.out.println("we are in Dog show class");
    } 

    public static void showMessage()
    {
        System.out.println("we are in overriddn method of dog class");
    }
}

public class AnimalTest { 

    public static void main(String [] args)
    {
        Animal animal = new Animal();
        animal.showMessage();

        Dog dog = new Dog();
        dog.DogShow();

        Animal animal2 = new Dog();
        animal2.showMessage();
    }

By the answer of rudivonstaden

txtBlock.Text = await response.Content.ReadAsStringAsync();

but if you don't want to make the method async you can use

txtBlock.Text = response.Content.ReadAsStringAsync();
txtBlock.Text.Wait();

Wait() it's important, bec?use we are doing async operations and we must wait for the task to complete before going ahead.

I'm guessing from your last question, asked 20 minutes before this one, that you are trying to parse (read and convert) the XML found through using GeoNames' FindNearestAddress.

If your XML is in a string variable called txt and looks like this:

<address>
  <street>Roble Ave</street>
  <mtfcc>S1400</mtfcc>
  <streetNumber>649</streetNumber>
  <lat>37.45127</lat>
  <lng>-122.18032</lng>
  <distance>0.04</distance>
  <postalcode>94025</postalcode>
  <placename>Menlo Park</placename>
  <adminCode2>081</adminCode2>
  <adminName2>San Mateo</adminName2>
  <adminCode1>CA</adminCode1>
  <adminName1>California</adminName1>
  <countryCode>US</countryCode>
</address>

Then you can parse the XML with Javascript DOM like this:

if (window.DOMParser)
{
    parser = new DOMParser();
    xmlDoc = parser.parseFromString(txt, "text/xml");
}
else // Internet Explorer
{
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async = false;
    xmlDoc.loadXML(txt);
}

And get specific values from the nodes like this:

//Gets house address number
xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue;

//Gets Street name
xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue;

//Gets Postal Code
xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue;

JSFiddle

Feb. 2019 edit:

In response to @gaugeinvariante's concerns about xml with Namespace prefixes. Should you have a need to parse xml with Namespace prefixes, everything should work almost identically:

NOTE: this will only work in browsers that support xml namespace prefixes such as Microsoft Edge

// XML with namespace prefixes 's', 'sn', and 'p' in a variable called txt_x000D_

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

Heroku has deprecated the --db option now, so now use:

heroku pg:reset DATABASE_URL --confirm {the name of your app}

It's a little confusing because you use the literal text SHARED_DATABASE but where I have written {the name of your app} substitute the name of your app. For example, if your app is called my_great_app then you use:

heroku pg:reset DATABASE_URL --confirm my_great_app

It's simpler if you pass an event parameter like this:

<a href="#" onclick="yes_js_login(event);">link</a>

function yes_js_login(e) {
    e.stopImmediatePropagation();
}

Different Environments

Typically, software will run in different environments:

• development
• testing
• staging
• production

Different Dependencies in Different Environments

The dependencies which are declared in the require section of composer.json are typically dependencies which are required for running an application or a package in

• staging
• production

environments, whereas the dependencies declared in the require-dev section are typically dependencies which are required in

• developing
• testing

environments.

For example, in addition to the packages used for actually running an application, packages might be needed for developing the software, such as:

• friendsofphp/php-cs-fixer (to detect and fix coding style issues)
• squizlabs/php_codesniffer (to detect and fix coding style issues)
• phpunit/phpunit (to drive the development using tests)
• etc.

Deployment

Now, in development and testing environments, you would typically run

$ composer install

to install both production and development dependencies.

However, in staging and production environments, you only want to install dependencies which are required for running the application, and as part of the deployment process, you would typically run

$ composer install --no-dev

to install only production dependencies.

Semantics

In other words, the sections

• require
• require-dev

indicate to composer which packages should be installed when you run

$ composer install

or

$ composer install --no-dev

That is all.

Note Development dependencies of packages your application or package depend on will never be installed

For reference, see:

• https://getcomposer.org/doc/04-schema.md#require
• https://getcomposer.org/doc/04-schema.md#require-dev

Another pure css based solution that is based on two clipped rounded elements that i rotate to get to the right angle:

http://jsfiddle.net/maayan/byT76/

That's the basic css that enables it:

.clip1 {
    position:absolute;
    top:0;left:0;
    width:200px;
    height:200px;
    clip:rect(0px,200px,200px,100px);
}
.slice1 {
    position:absolute;
    width:200px;
    height:200px;
    clip:rect(0px,100px,200px,0px);
    -moz-border-radius:100px;
    -webkit-border-radius:100px; 
    border-radius:100px;
    background-color:#f7e5e1;
    border-color:#f7e5e1;
    -moz-transform:rotate(0);
    -webkit-transform:rotate(0);
    -o-transform:rotate(0);
    transform:rotate(0);
}

.clip2 
{
    position:absolute;
    top:0;left:0;
    width:200px;
    height:200px;
    clip:rect(0,100px,200px,0px);
}

.slice2
{
    position:absolute;
    width:200px;
    height:200px;
    clip:rect(0px,200px,200px,100px);
    -moz-border-radius:100px;
    -webkit-border-radius:100px; 
    border-radius:100px;
    background-color:#f7e5e1;
    border-color:#f7e5e1;
    -moz-transform:rotate(0);
    -webkit-transform:rotate(0);
    -o-transform:rotate(0);
    transform:rotate(0);
}

and the js rotates it as required.

quite easy to understand..

Hope it helps, Maayan

This function will return true if it's Date or false otherwise:

function isDate(myDate) {
    return myDate.constructor.toString().indexOf("Date") > -1;
} 

The best "Pythonic" way to do this, exploiting the with statement, is listed as Example #6 in PEP 343, which gives the background of the statement.

@contextmanager
def opened_w_error(filename, mode="r"):
    try:
        f = open(filename, mode)
    except IOError, err:
        yield None, err
    else:
        try:
            yield f, None
        finally:
            f.close()

Used as follows:

with opened_w_error("/etc/passwd", "a") as (f, err):
    if err:
        print "IOError:", err
    else:
        f.write("guido::0:0::/:/bin/sh\n")

If you don't want to use seperate npm package body-parser, latest express (4.16+) has built-in body-parser middleware and can be used like this,

const app = express();
app.use(express.json({ limit: '100mb' }));

p.s. Not all functionalities of body parse are present in the express. Refer documentation for full usage here

I had to quit Intellij and remove the .idea folder (I stashed it first, just in case). I then re-opened the project and that worked for me. Don't forget to save your configuration (e.g. debug / run configurations) before that, because they will also be deleted.

Italy:

>>> import locale
>>> locale.setlocale(locale.LC_ALL,"")
'Italian_Italy.1252'
>>> f"{1000:n}"
'1.000'

No, you don't need to do anything with AndroidManifest.xml

Basically, your app's version name and version code is inside the app level Gradle file, under defaultConfig tag:

defaultConfig {
   versionCode 1
   versionName "1.0"
}

Note: When you wish to upload an app to the playstore, it can give any name as the version name, but the version code have to be different than the current version code if this app is already in the play store.

Simply use the following code snippet to get the version code & version name from anywhere in your app:

try {
    PackageInfo pInfo =   context.getPackageManager().getPackageInfo(context.getPackageName(), 0);
    String version = pInfo.versionName;
    int verCode = pInfo.versionCode;
} catch (PackageManager.NameNotFoundException e) {
    e.printStackTrace();
}

In my case, I was mistaken the function parameters, which are:

context.drawImage(image, left, top);
context.drawImage(image, left, top, width, height);

If you expect them to be

context.drawImage(image, width, height);

you will place the image just outside the canvas with the same effects as described in the question.

Git creates a master branch once you've done your first commit. There's nothing to have a branch for if there's no code in the repository.

For a project I'm working on, I wrote a simple ko.unapplyBindings function that accepts a jQuery node and the remove boolean. It first unbinds all jQuery events as ko.cleanNode method doesn't take care of that. I've tested for memory leaks, and it appears to work just fine.

ko.unapplyBindings = function ($node, remove) {
    // unbind events
    $node.find("*").each(function () {
        $(this).unbind();
    });

    // Remove KO subscriptions and references
    if (remove) {
        ko.removeNode($node[0]);
    } else {
        ko.cleanNode($node[0]);
    }
};

The difference between List and LinkedList lies in their underlying implementation. List is array based collection (ArrayList). LinkedList is node-pointer based collection (LinkedListNode). On the API level usage, both of them are pretty much the same since both implement same set of interfaces such as ICollection, IEnumerable, etc.

The key difference comes when performance matter. For example, if you are implementing the list that has heavy "INSERT" operation, LinkedList outperforms List. Since LinkedList can do it in O(1) time, but List may need to expand the size of underlying array. For more information/detail you might want to read up on the algorithmic difference between LinkedList and array data structures. http://en.wikipedia.org/wiki/Linked_list and Array

Hope this help,

Try to use this:

public Bitmap getBitmapFromURL(String src) {
    try {
        java.net.URL url = new java.net.URL(src);
        HttpURLConnection connection = (HttpURLConnection) url
                .openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

And for OutOfMemory issue:

 public Bitmap getResizedBitmap(Bitmap bm, int newHeight, int newWidth) {
    int width = bm.getWidth();
    int height = bm.getHeight();
    float scaleWidth = ((float) newWidth) / width;
    float scaleHeight = ((float) newHeight) / height;
    // CREATE A MATRIX FOR THE MANIPULATION
    Matrix matrix = new Matrix();
    // RESIZE THE BIT MAP
    matrix.postScale(scaleWidth, scaleHeight);

    // "RECREATE" THE NEW BITMAP
    Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height,
            matrix, false);

    return resizedBitmap;
}

You can use expand.grid( ) function.

x <-c(1,2,3)
y <-c(100,200,300)
expand.grid(cond=x,rating=y)

Assuming you have two log-files in:

• C:/temp/my.log
• C:/temp/alsoMy.log

cd to C: and use:

grep -r somethingtosearch temp/*.log

It will give you a list like:

temp/my.log:somethingtosearch
temp/alsoMy.log:somethingtosearch1
temp/alsoMy.log:somethingtosearch2

Ok so this might be the very best option for shallow copying. If follows the many examples using assign, but it also keeps the inheritance and prototype. It's so simple too and works for most array-like and Objects except those with constructor requirements or read-only properties. But that means it fails miserably for TypedArrays, RegExp, Date, Maps, Sets and Object versions of primitives (Boolean, String, etc..).

function copy ( a ) { return Object.assign( new a.constructor, a ) }

Where a can be any Object or class constructed instance, but again not be reliable for thingies that use specialized getters and setters or have constructor requirements, but for more simple situations it rocks. It does work on arguments as well.

You can also apply it to primitives to get strange results, but then... unless it just ends up being a useful hack, who cares.

results from basic built-in Object and Array...

> a = { a: 'A', b: 'B', c: 'C', d: 'D' }
{ a: 'A', b: 'B', c: 'C', d: 'D' }
> b = copy( a )
{ a: 'A', b: 'B', c: 'C', d: 'D' }
> a = [1,2,3,4]
[ 1, 2, 3, 4 ]
> b = copy( a )
[ 1, 2, 3, 4 ]

And fails because of mean get/setters, constructor required arguments or read-only properties, and sins against the father.

> a = /\w+/g
/\w+/g
> b = copy( a )  // fails because source and flags are read-only
/(?:)/
> a = new Date ( '1/1/2001' )
2000-12-31T16:00:00.000Z
> b = copy( a )  // fails because Date using methods to get and set things
2017-02-04T14:44:13.990Z
> a = new Boolean( true )
[Boolean: true]
> b = copy( a )  // fails because of of sins against the father
[Boolean: false]
> a = new Number( 37 )
[Number: 37]
> b = copy( a )  // fails because of of sins against the father
[Number: 0]
> a = new String( 'four score and seven years ago our four fathers' )
[String: 'four score and seven years ago our four fathers']
> b = copy( a )  // fails because of of sins against the father

I was getting this error when executing in python3,I got the same program working by simply executing in python2

the worked proposition for me is __call__ on class who create list of little numbers:

        for cmb in range(2, len(str(self.how_much)) + 1):

It is worth mentioning that 2>&1 means that standard error will be redirected too, together with standard output. So

someCommand | tee someFile

gives you just the standard output in the file, but not the standard error: standard error will appear in console only. To get standard error in the file too, you can use

someCommand 2>&1 | tee someFile

(source: In the shell, what is " 2>&1 "? ). Finally, both the above commands will truncate the file and start clear. If you use a sequence of commands, you may want to get output&error of all of them, one after another. In this case you can use -a flag to "tee" command:

someCommand 2>&1 | tee -a someFile

Are you trying to find some work around getting xpath in IE?

There are many add-ons for other browsers like xpather for Chrome or xpather, xpath-checker and firebug for FireFox that will give you the xpath of an element in a second. But sadly there is no add-on or tool available that will do this for IE. For most cases you can get the xpath of the elements that fall in your script using the above tools in Firefox and tweak them a little (if required) to make them work in IE.

But if you are testing an application that will work only in IE or the specific scenario or page that has this element will open-up/play-out only in IE then you cannot use any of the above mention tools to find the XPATH. Well the only thing that works in this case is the Bookmarklets that were coded just for this purpose. Bookmarklets are JavaScript code that you will add in IE as bookmarks and later use to get the XPATH of the element you desire. Using these you can get the XPATH as easily as you get using xpather or any other firefox addon.

STEPS TO INSTALL BOOKMARKLETS

1)Open IE

2)Type about:blank in the address bar and hit enter

3)From Favorites main menu select ---> Add favorites

4) In the Add a favorite popup window enter name GetXPATH1.

5)Click add button in the add a favorite popup window.

6)Open the Favorites menu and right click the newly added favorite and select properties option.

7)GetXPATH1 Properties will open up. Select the web Document Tab.

8)Enter the following in the URL field.

javascript:function getNode(node){var nodeExpr=node.tagName;if(!nodeExpr)return null;if(node.id!=''){nodeExpr+="[@id='"+node.id+"']";return "/"+nodeExpr;}var rank=1;var ps=node.previousSibling;while(ps){if(ps.tagName==node.tagName){rank++;}ps=ps.previousSibling;}if(rank>1){nodeExpr+='['+rank+']';}else{var ns=node.nextSibling;while(ns){if(ns.tagName==node.tagName){nodeExpr+='[1]';break;}ns=ns.nextSibling;}}return nodeExpr;}

9)Click Ok. Click YES on the popup alert.

10)Add another favorite by following steps 3 to 5, Name this favorite GetXPATH2 (step4)

11)Repeat steps 6 and 7 for GetXPATH2 that you just created.

12)Enter the following in the URL field for GetXPATH2

javascript:function o__o(){var currentNode=document.selection.createRange().parentElement();var path=[];while(currentNode){var pe=getNode(currentNode);if(pe){path.push(pe);if(pe.indexOf('@id')!=-1)break;}currentNode=currentNode.parentNode;}var xpath="/"+path.reverse().join('/');clipboardData.setData("Text", xpath);}o__o();

13)Repeat Step 9.

You are all done!!

Now to get the XPATH of elements just select the element with your mouse. This would involve clicking the left mouse button just before the element (link, button, image, checkbox, text etc) begins and dragging it till the element ends. Once you do this first select the favorite GetXPATH1 from the favorites menu and then select the second favorite GetXPATH2. At this point you will get a confirmation, hit allow access button. Now open up a notepad file, right click and select paste option. This will give you the XPATH of the element you seek.

I started with johncarls solution, but needed to adjust it to get exactly what I needed. Mainly, I needed it to rotate clockwise when the angle increased. I also needed 0 degrees to point NORTH. His solution got me close, but I decided to post my solution as well in case it helps anyone else.

I've added some additional comments to help explain my understanding of the function in case you need to make simple modifications.

/**
 * Calculates the angle from centerPt to targetPt in degrees.
 * The return should range from [0,360), rotating CLOCKWISE, 
 * 0 and 360 degrees represents NORTH,
 * 90 degrees represents EAST, etc...
 *
 * Assumes all points are in the same coordinate space.  If they are not, 
 * you will need to call SwingUtilities.convertPointToScreen or equivalent 
 * on all arguments before passing them  to this function.
 *
 * @param centerPt   Point we are rotating around.
 * @param targetPt   Point we want to calcuate the angle to.  
 * @return angle in degrees.  This is the angle from centerPt to targetPt.
 */
public static double calcRotationAngleInDegrees(Point centerPt, Point targetPt)
{
    // calculate the angle theta from the deltaY and deltaX values
    // (atan2 returns radians values from [-PI,PI])
    // 0 currently points EAST.  
    // NOTE: By preserving Y and X param order to atan2,  we are expecting 
    // a CLOCKWISE angle direction.  
    double theta = Math.atan2(targetPt.y - centerPt.y, targetPt.x - centerPt.x);

    // rotate the theta angle clockwise by 90 degrees 
    // (this makes 0 point NORTH)
    // NOTE: adding to an angle rotates it clockwise.  
    // subtracting would rotate it counter-clockwise
    theta += Math.PI/2.0;

    // convert from radians to degrees
    // this will give you an angle from [0->270],[-180,0]
    double angle = Math.toDegrees(theta);

    // convert to positive range [0-360)
    // since we want to prevent negative angles, adjust them now.
    // we can assume that atan2 will not return a negative value
    // greater than one partial rotation
    if (angle < 0) {
        angle += 360;
    }

    return angle;
}

To update each submodule, you could invoke the following command (at the root of the repository):

git submodule -q foreach git pull -q origin master

You can remove the -q option to follow the whole process.

This is more a long comment on @Sergey and @Steffen's answers. Having written similar code myself in the past I decided to check what was most performant while remembering that clarity is important too.

Result

Here is an example test run result for 10 million iterations:

2257 ms for FirstDayOfMonth_AddMethod()
2406 ms for FirstDayOfMonth_NewMethod()
6342 ms for LastDayOfMonth_AddMethod()
4037 ms for LastDayOfMonth_AddMethodWithDaysInMonth()
4160 ms for LastDayOfMonth_NewMethod()
4212 ms for LastDayOfMonth_NewMethodWithReuseOfExtMethod()
2491 ms for LastDayOfMonth_SpecialCase()

Code

I used LINQPad 4 (in C# Program mode) to run the tests with compiler optimization turned on. Here is the tested code factored as Extension methods for clarity and convenience:

public static class DateTimeDayOfMonthExtensions
{
    public static DateTime FirstDayOfMonth_AddMethod(this DateTime value)
    {
        return value.Date.AddDays(1 - value.Day);
    }
    
    public static DateTime FirstDayOfMonth_NewMethod(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, 1);
    }
    
    public static DateTime LastDayOfMonth_AddMethod(this DateTime value)
    {
        return value.FirstDayOfMonth_AddMethod().AddMonths(1).AddDays(-1);
    }
    
    public static DateTime LastDayOfMonth_AddMethodWithDaysInMonth(this DateTime value)
    {
        return value.Date.AddDays(DateTime.DaysInMonth(value.Year, value.Month) - value.Day);
    }
    
    public static DateTime LastDayOfMonth_SpecialCase(this DateTime value)
    {
        return value.AddDays(DateTime.DaysInMonth(value.Year, value.Month) - 1);
    }
    
    public static int DaysInMonth(this DateTime value)
    {
        return DateTime.DaysInMonth(value.Year, value.Month);
    }

Analysis

I was surprised by some of these results.

Although there is not much in it the FirstDayOfMonth_AddMethod was slightly faster than FirstDayOfMonth_NewMethod in most runs of the test. However, I think the latter has a slightly clearer intent and so I have a preference for that.

LastDayOfMonth_AddMethod was a clear loser against LastDayOfMonth_AddMethodWithDaysInMonth, LastDayOfMonth_NewMethod and LastDayOfMonth_NewMethodWithReuseOfExtMethod. Between the fastest three there is nothing much in it and so it comes down to your personal preference. I choose the clarity of LastDayOfMonth_NewMethodWithReuseOfExtMethod with its reuse of another useful extension method. IMHO its intent is clearer and I am willing to accept the small performance cost.

LastDayOfMonth_SpecialCase assumes you are providing the first of the month in the special case where you may have already calculated that date and it uses the add method with DateTime.DaysInMonth to get the result. This is faster than the other versions, as you would expect, but unless you are in a desperate need for speed I don't see the point of having this special case in your arsenal.

Conclusion

Here is an extension method class with my choices and in general agreement with @Steffen I believe:

public static class DateTimeDayOfMonthExtensions
{
    public static DateTime FirstDayOfMonth(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, 1);
    }
    
    public static int DaysInMonth(this DateTime value)
    {
        return DateTime.DaysInMonth(value.Year, value.Month);
    }
    
    public static DateTime LastDayOfMonth(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, value.DaysInMonth());
    }
}

If you have got this far, thank you for time! Its been fun :¬). Please comment if you have any other suggestions for these algorithms.

This question is old, but still relevant.

If you want to compare two maps by their values matching their keys, you can do as follows:

public static <K, V> boolean mapEquals(Map<K, V> leftMap, Map<K, V> rightMap) {
    if (leftMap == rightMap) return true;
    if (leftMap == null || rightMap == null || leftMap.size() != rightMap.size()) return false;
    for (K key : leftMap.keySet()) {
        V value1 = leftMap.get(key);
        V value2 = rightMap.get(key);
        if (value1 == null && value2 == null)
            continue;
        else if (value1 == null || value2 == null)
            return false;
        if (!value1.equals(value2))
            return false;
    }
    return true;
}

According the MDN custom headers are not exposed by default. The server admin need to expose them using "Access-Control-Expose-Headers" in the same fashion they deal with "access-control-allow-origin"

See this MDN link for confirmation [https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Expose-Headers]

1. Well, of course, you can instantiate the other controller and call the method you want. Probably it's not a good practice but I don't know why:

$otherController = new OtherController();
$otherController->methodFromOtherController($param1, $param2 ...);

2. But, doing this, you will have a problem: the other method returns something like response()->json($result), and is not it what you want.

3. To resolve this problem, define the first parameter of the other controller's method as:

public function methodFromOtherController(Request $request = null, ...

4. When you call methodFromOtherController from the main controller, you will pass null as first parameter value:

$otherController = new OtherController();
$otherController->methodFromOtherController(null, $param1, $param2 ...);

5. Finally, create a condition at the end of the methodFromOtherController method:

public function methodFromOtherController(Request $request = null, ...) 
{
  ...
  if (is_null($request)) {
    return $result;
  } else {
    return response()->json($result);
  }
}

6. Once Laravel you ever set $request when it is called by direct route, you can differentiate each situation and return a correspondent value.

Not to necro a thread, but under the latest version of jQuery the suggested syntax is:

$( handler )

Using an anonymous function, this would look like

$(function() { ... insert code here ... });

See this link:

This gave me accurate results every time...

This is in my Stripes field...

Yellow, Yellow, Yellow, Yellow, Yellow, Yellow, Black, Yellow, Yellow, Red, Yellow, Yellow, Yellow, Black

• 11 Yellows
• 2 Black
• 1 Red

SELECT (LEN(Stripes) - LEN(REPLACE(Stripes, 'Red', ''))) / LEN('Red') 
  FROM t_Contacts

You could find the difference between dates in columns in a data frame by using the function difftime as follows:

df$diff_in_days<- difftime(df$datevar1 ,df$datevar2 , units = c("days"))

If you know you're going offline for a while, you can close your connection, do your processing, reconnect and write your reports.

For this (and most plotting) I would not rely on the Pandas wrappers to matplotlib. Instead, just use matplotlib directly:

import matplotlib.pyplot as plt
plt.scatter(df['col_name_1'], df['col_name_2'])
plt.show() # Depending on whether you use IPython or interactive mode, etc.

and remember that you can access a NumPy array of the column's values with df.col_name_1.values for example.

I ran into trouble using this with Pandas default plotting in the case of a column of Timestamp values with millisecond precision. In trying to convert the objects to datetime64 type, I also discovered a nasty issue: < Pandas gives incorrect result when asking if Timestamp column values have attr astype >.

In Excel, the substring function is called MID function, and indexOf is called FIND for case-sensitive location and SEARCH function for non-case-sensitive location. For the first portion of your text parsing the LEFT function may also be useful.

    var keyCode = e.keyCode || e.which;

    if (keyCode === 9) {
        e.preventDefault();
        var start = this.selectionStart;
        var end = this.selectionEnd;
        var val = this.value;
        var selected = val.substring(start, end);
        var re = /^/gm;
        var count = selected.match(re).length;


        this.value = val.substring(0, start) + selected.replace(re, '\t') + val.substring(end);
        this.selectionStart = start;
        this.selectionEnd = end + count;
    }
});

In general, you can add a View in a specific position using a FrameLayout as container by specifying the leftMargin and topMargin attributes.

The following example will place a 20x20px ImageView at position (100,200) using a FrameLayout as fullscreen container:

XML

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/root"
    android:background="#33AAFF"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
</FrameLayout>

Activity / Fragment / Custom view

//...
FrameLayout root = (FrameLayout)findViewById(R.id.root);
ImageView img = new ImageView(this);
img.setBackgroundColor(Color.RED);
//..load something inside the ImageView, we just set the background color

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(20, 20);
params.leftMargin = 100;
params.topMargin  = 200;
root.addView(img, params);
//...

This will do the trick because margins can be used as absolute (X,Y) coordinates without a RelativeLayout:

I doubt that Subclipse and then SVN can use your Eclipse proxy settings. You'll probably need to set the proxy for your SVN program itself. Trying to check out the files using SVN from the command line should tell you if that works.

If SVN can't connect either then put the proxy settings in your servers file in your Subversion settings folder (in your home folder).

If it can't do it even with the proxy settings set, then your firewall is probably blocking the methods and protocols that Subversion needs to use to download the files.

Jenkins 2.9

1. Jenkins > New Item

   

2. Enter an item name - E.g. "MY_CLONE"

   

3. Specify the source (Copy from) job > OK

   When you start typing the name, the existing values will be found. Notice that this is case sensitive.

   

4. Click on Save if you want to keep the default values.

5. Now both jobs are available in the same location:

   

This is probably obvious, but simplest:

i64 := int64(23)

The variable to use would be process.platform

On Mac the variable returns darwin. On Windows, it returns win32 (even on 64 bit).

Current possible values are:

• aix
• darwin
• freebsd
• linux
• openbsd
• sunos
• win32

I just set this at the top of my jakeFile:

var isWin = process.platform === "win32";

Well, at the risk of making things too easy...

for (var member in myObject) delete myObject[member];

...would seem to be pretty effective in cleaning the object in one line of code with a minimum of scary brackets. All members will be truly deleted instead of left as garbage.

Obviously if you want to delete the object itself, you'll still have to do a separate delete() for that.

$('#test').attr('id') In your example:

<div id="test"></div>

$(document).ready(function() {
    alert($('#test').attr('id'));
}); 

Either in your admin.py or in a separate forms.py you can add a ModelForm class and then declare your extra fields inside that as you normally would. I've also given an example of how you might use these values in form.save():

from django import forms
from yourapp.models import YourModel


class YourModelForm(forms.ModelForm):

    extra_field = forms.CharField()

    def save(self, commit=True):
        extra_field = self.cleaned_data.get('extra_field', None)
        # ...do something with extra_field here...
        return super(YourModelForm, self).save(commit=commit)

    class Meta:
        model = YourModel

To have the extra fields appearing in the admin just:

1. edit your admin.py and set the form property to refer to the form you created above
2. include your new fields in your fields or fieldsets declaration

Like this:

class YourModelAdmin(admin.ModelAdmin):

    form = YourModelForm

    fieldsets = (
        (None, {
            'fields': ('name', 'description', 'extra_field',),
        }),
    )

UPDATE: In django 1.8 you need to add fields = '__all__' to the metaclass of YourModelForm.

You can do this.

bonus_rows = []
for a in myarr:
  if somecond(a):
      bonus_rows.append(newObj())
myarr.extend( bonus_rows )

You can use something like this.

$ cat test_file.txt
54 68 69 73 20 69 73 20 74 65 78 74 20 64 61 74 61 2e 0a 4f 6e 65 20 6d 6f 72 65 20 6c 69 6e 65 20 6f 66 20 74 65 73 74 20 64 61 74 61 2e

$ for c in `cat test_file.txt`; do printf "\x$c"; done;
This is text data.
One more line of test data.

In case you want to do it programmatically,

checkBoxOrRadioButton.setButtonDrawable(null);
checkBoxOrRadioButton.setBackgroundResource(R.drawable.resource_name);

you can use the new push/pop state functions in the history manipulation API.

you can write to a unit, but you can also write to a string

program foo
    character(len=1024) :: filename

    write (filename, "(A5,I2)") "hello", 10

    print *, trim(filename)
end program

Please note (this is the second trick I was talking about) that you can also build a format string programmatically.

program foo

    character(len=1024) :: filename
    character(len=1024) :: format_string
    integer :: i

    do i=1, 10
        if (i < 10) then
            format_string = "(A5,I1)"
        else
            format_string = "(A5,I2)"
        endif

        write (filename,format_string) "hello", i
        print *, trim(filename)
    enddo

end program

range creates a list, so if you do range(1, 10000000) it creates a list in memory with 10000000 elements. xrange is a generator, so it evaluates lazily.

This brings you two advantages:

1. You can iterate longer lists without getting a MemoryError.
2. As it resolves each number lazily, if you stop iteration early, you won't waste time creating the whole list.

I had an example where I was looking up and because one table held the value as a double, the other as a string, they would not match (or not match without a cast). But only NOT IN. As SELECT ... IN ... worked. Weird, but thought I would share in case anyone else encounters this simple fix.

As others have answered, you need multiple ALTER TABLE statements.
Try following:

ALTER TABLE tblcommodityOHLC alter column CC_CommodityContractID NUMERIC(18,0);
ALTER TABLE tblcommodityOHLC alter column CM_CommodityID NUMERIC(18,0);

If you are doing this in a DB upgrade statement, perhaps the simplest way is to just catch the exception thrown if you are attempting to add a field that may already exist.

try {
   db.execSQL("ALTER TABLE " + TABLE_NAME + " ADD COLUMN foo TEXT default null");
} catch (SQLiteException ex) {
   Log.w(TAG, "Altering " + TABLE_NAME + ": " + ex.getMessage());
}

The main reason for this is when the database is open somewhere else.

This could be as already said by many others:

• not being closed properly somewhere
• already open somewhere

When recently I had the same problem although different versions, I started to search for the reason.

In my case I had an excel file that queried data from the database.

In case the excel file is opened before the database, access would give this error.

Conclusion:

Check all files/connections related to the database. An open ODBC connection or query used in excel (my case) open the mdb file and will make it readonly.

This happens due to current branch has no tracking on the branch on the remote. so you can do it with 2 ways.

1. Pull with specific branch name

git pull origin master

2. Or you can specific branch to track to the local branch.

git branch --set-upstream-to=origin/

For those with a git gui bent, you can also use gitk.

Right click on the commit you want to return to and select "Reset master branch to here". Then choose hard from the next menu.

From Docker 17.06 onwards, a special Mac-only DNS name is available in docker containers that resolves to the IP address of the host. It is:

A simple solution for a delayed auto submit:

<body onload="setTimeout(function() { document.frm1.submit() }, 5000)">
   <form action="https://www.google.com" name="frm1">
      <input type="hidden" name="q" value="Hello world" />
   </form>
</body>

this is one:

ls -l . | egrep -c '^-'

Note:

ls -1 | wc -l

Which means: ls: list files in dir

-1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

|: pipe output onto...

wc: "wordcount"

-l: count lines.

MORE ANSWERS! Here is the solution i used

\"([^\"]*?icon[^\"]*?)\"

TLDR;
replace the word icon with what your looking for in said quotes and voila!

The way this works is it looks for the keyword and doesn't care what else in between the quotes. EG:
id="fb-icon"
id="icon-close"
id="large-icon-close"
the regex looks for a quote mark "
then it looks for any possible group of letters thats not "
until it finds icon
and any possible group of letters that is not "
it then looks for a closing "

String.equalsIgnoreCase is the most practical choice for naive case-insensitive string comparison.

However, it is good to be aware that this method does neither do full case folding nor decomposition and so cannot perform caseless matching as specified in the Unicode standard. In fact, the JDK APIs do not provide access to information about case folding character data, so this job is best delegated to a tried and tested third-party library.

That library is ICU, and here is how one could implement a utility for case-insensitive string comparison:

import com.ibm.icu.text.Normalizer2;

// ...

public static boolean equalsIgnoreCase(CharSequence s, CharSequence t) {
    Normalizer2 normalizer = Normalizer2.getNFKCCasefoldInstance();
    return normalizer.normalize(s).equals(normalizer.normalize(t));
}

    String brook = "?u\u0308ßchen";
    String BROOK = "FLÜSSCHEN";

    assert equalsIgnoreCase(brook, BROOK);

Naive comparison with String.equalsIgnoreCase, or String.equals on upper- or lowercased strings will fail even this simple test.

(Do note though that the predefined case folding flavour getNFKCCasefoldInstance is locale-independent; for Turkish locales a little more work involving UCharacter.foldCase may be necessary.)

target isn't valid on an input element.

In this case, though, your redirection is done by Javascript, so you could have your script open up a new window.

There is no "standard place" for a sqlite database. The file's location is specified to the library, and may be in your home directory, in the invoking program's folder, or any other place.

If it helps, sqlite databases are, by convention, named with a .db file extension.

Whatever TomDLT answered it may not work for some of you because

data1 = pd.DataFrame(data= np.c_[iris['data'], iris['target']],
                 columns= iris['feature_names'] + ['target'])

because iris['feature_names'] returns you a numpy array. In numpy array you can't add an array and a list ['target'] by just + operator. Hence you need to convert it into a list first and then add.

You can do

data1 = pd.DataFrame(data= np.c_[iris['data'], iris['target']],
                 columns= list(iris['feature_names']) + ['target'])

This will work fine tho..

Given a question so thoroughly answered why not add another

This suits my aesthetic a little better, though many of the above are comparable

import numpy as np

number=-456.789
significantFigures=4

roundingFactor=significantFigures - int(np.floor(np.log10(np.abs(number)))) - 1
rounded=np.round(number, roundingFactor)

string=rounded.astype(str)

print(string)

This works for individual numbers and numpy arrays, and should function fine for negative numbers.

There's one additional step we might add - np.round() returns a decimal number even if rounded is an integer (i.e. for significantFigures=2 we might expect to get back -460 but instead we get -460.0). We can add this step to correct for that:

if roundingFactor<=0:
    rounded=rounded.astype(int)

Unfortunately, this final step won't work for an array of numbers - I'll leave that to you dear reader to figure out if you need.

The <h:outputLink> renders a fullworthy HTML <a> element with the proper URL in the href attribute which fires a bookmarkable GET request. It cannot directly invoke a managed bean action method.

<h:outputLink value="destination.xhtml">link text</h:outputLink>

The <h:commandLink> renders a HTML <a> element with an onclick script which submits a (hidden) POST form and can invoke a managed bean action method. It's also required to be placed inside a <h:form>.

<h:form>
    <h:commandLink value="link text" action="destination" />
</h:form>

The ?faces-redirect=true parameter on the <h:commandLink>, which triggers a redirect after the POST (as per the Post-Redirect-Get pattern), only improves bookmarkability of the target page when the link is actually clicked (the URL won't be "one behind" anymore), but it doesn't change the href of the <a> element to be a fullworthy URL. It still remains #.

<h:form>
    <h:commandLink value="link text" action="destination?faces-redirect=true" />
</h:form>

Since JSF 2.0, there's also the <h:link> which can take a view ID (a navigation case outcome) instead of an URL. It will generate a HTML <a> element as well with the proper URL in href.

<h:link value="link text" outcome="destination" />

So, if it's for pure and bookmarkable page-to-page navigation like the SO username link, then use <h:outputLink> or <h:link>. That's also better for SEO since bots usually doesn't cipher POST forms nor JS code. Also, UX will be improved as the pages are now bookmarkable and the URL is not "one behind" anymore.

When necessary, you can do the preprocessing job in the constructor or @PostConstruct of a @RequestScoped or @ViewScoped @ManagedBean which is attached to the destination page in question. You can make use of @ManagedProperty or <f:viewParam> to set GET parameters as bean properties.

See also:

• ViewParam vs @ManagedProperty(value = "#{param.id}")
• What can <f:metadata>, <f:viewParam> and <f:viewAction> be used for?

If you are using pwsh (powershell core), you can try

(docker ps --format='{{json .}}' |  ConvertFrom-Json).Mounts

also you can see both container name and Mounts as below

docker ps --format='{{json .}}' |  ConvertFrom-Json | select Names,Mounts

As the output is converted as json ,you can get any properties it has.

First of all, beware of finding old examples. You've found one that uses XmlTextWriter, which is deprecated as of .NET 2.0. XmlWriter.Create should be used instead.

Here's an example of serializing an object into an XML column:

public void SerializeToXmlColumn(object obj)
{
    using (var outputStream = new MemoryStream())
    {
        using (var writer = XmlWriter.Create(outputStream))
        {
            var serializer = new XmlSerializer(obj.GetType());
            serializer.Serialize(writer, obj);
        }

        outputStream.Position = 0;
        using (var conn = new SqlConnection(Settings.Default.ConnectionString))
        {
            conn.Open();

            const string INSERT_COMMAND = @"INSERT INTO XmlStore (Data) VALUES (@Data)";
            using (var cmd = new SqlCommand(INSERT_COMMAND, conn))
            {
                using (var reader = XmlReader.Create(outputStream))
                {
                    var xml = new SqlXml(reader);

                    cmd.Parameters.Clear();
                    cmd.Parameters.AddWithValue("@Data", xml);
                    cmd.ExecuteNonQuery();
                }
            }
        }
    }
}

If you go to references, click on the Entity Framework, view properties It will tell you the version number.

Trust store generally (actually should only contain root CAs but this rule is violated in general) contains the certificates that of the root CAs (public CAs or private CAs). You can verify the list of certs in trust store using

keytool -list -v -keystore truststore.jks

Looks like the $state->name variable is holding an array. You can use

var_dump($state)

inside the foreach to test that.

If that's the case, you can change the line inside the foreach to

$states[]= array('state' => array_shift($state->name)); 

to correct it.

When inserting a row, regardless of the CopyOrigin, Excel will only put vertical borders on the inserted cells if the borders above and below the insert position are the same.

I'm running into a similar (but rotated) situation with inserting columns, but Copy/Paste is too slow for my workbook (tens of thousands of rows, many columns, and complex formatting).

I've found three workarounds that don't require copying the formatting from the source row:

1. Ensure the vertical borders are the same weight, color, and pattern above and below the insert position so Excel will replicate them in your new row. (This is the "It hurts when I do this," "Stop doing that!" answer.)

2. Use conditional formatting to establish the border (with a Formula of "=TRUE"). The conditional formatting will be copied to the new row, so you still end up with a border.Caveats:

   • Conditional formatting borders are limited to the thin-weight lines.
   • Works best for sheets where borders are relatively consistent so you don't have to create a bunch of conditional formatting rules.

3. Set the border on the inserted row in VBA after inserting the row. Setting a border on a range is much faster than copying and pasting all of the formatting just to get a border (assuming you know ahead of time what the border should be or can sample it from the row above without losing performance).

Getters and setters coming from data hiding. Data Hiding means We are hiding data from outsiders or outside person/thing cannot access our data.This is a useful feature in OOP.

As a example:

If you create a public variable, you can access that variable and change value in anywhere(any class). But if you create as private that variable cannot see/access in any class except declared class.

public and private are access modifiers.

So how can we access that variable outside:

This is the place getters and setters coming from. You can declare variable as private then you can implement getter and setter for that variable.

Example(Java):

private String name;

public String getName(){
   return this.name;
}

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

Advantage:

When anyone want to access or change/set value to balance variable, he/she must have permision.

//assume we have person1 object
//to give permission to check balance
person1.getName()

//to give permission to set balance
person1.setName()

You can set value in constructor also but when later on when you want to update/change value, you have to implement setter method.

I have used Eclipse with the CDT plug in quite successfully.

There are many answers on how to create a memory leak in Java, but please note the point asked during the interview.

"how to create a memory leak with Java?" is an open-ended question, whose purpose is to evaluate the degree of experience a developer has.

If I ask you "Do you have experience troubleshooting memory leaks in Java?", your answer would be a simple "Yes". I would have then to follow up with "Could you give me examples where you hat to troubleshoot memory leaks?", to which you would give me one or two examples.

However, when the interviewer asks "how to create a memory leak with Java?" the expected answer should follow alongs these lines:

• I've encountered a memory leak ... (say when) [that shows me experience]
• The code that was causing it was... (explain code) [you fixed it yourself]
• The fix I applied was based on ... (explain fix) [this gives me a chance to ask specifics about the fix]
• The test I did was ... [gives me the chance of asking other testing methodologies]
• I documented it this way ... [extra points. Good if you documented it]
• So, it is reasonable to think that, if we follow this in reverse order, which is, get the code I fixed, and remove my fix, that we would have a memory leak.

When the developer fails to follow this line of thought I try to guide him/her asking "Could you give me an example of how could Java leak memory?", followed by "Did you ever have to fix any memory leak in Java?"

Note that I am not asking for an example on how to leak memory in Java. That would be silly. Who would be interested in a developer who can effectively write code that leaks memory?

Guys thank you for your help. I think all of this answers works. However i think my byte array contains raw bytes. That's why all of those solutions didnt work for my code.

However i found a solution. Maybe this solution helps other coders who have problem like mine.

static byte[] PadLines(byte[] bytes, int rows, int columns) {
   int currentStride = columns; // 3
   int newStride = columns;  // 4
   byte[] newBytes = new byte[newStride * rows];
   for (int i = 0; i < rows; i++)
       Buffer.BlockCopy(bytes, currentStride * i, newBytes, newStride * i, currentStride);
   return newBytes;
 }

 int columns = imageWidth;
 int rows = imageHeight;
 int stride = columns;
 byte[] newbytes = PadLines(imageData, rows, columns);

 Bitmap im = new Bitmap(columns, rows, stride, 
          PixelFormat.Format8bppIndexed, 
          Marshal.UnsafeAddrOfPinnedArrayElement(newbytes, 0));

 im.Save("C:\\Users\\musa\\Documents\\Hobby\\image21.bmp");

This solutions works for 8bit 256 bpp (Format8bppIndexed). If your image has another format you should change PixelFormat .

And there is a problem with colors right now. As soon as i solved this one i will edit my answer for other users.

*PS = I am not sure about stride value but for 8bit it should be equal to columns.

And also this function Works for me.. This function copies 8 bit greyscale image into a 32bit layout.

public void SaveBitmap(string fileName, int width, int height, byte[] imageData)
        {

            byte[] data = new byte[width * height * 4];

            int o = 0;

            for (int i = 0; i < width * height; i++)
            {
                byte value = imageData[i];


                data[o++] = value;
                data[o++] = value;
                data[o++] = value;
                data[o++] = 0; 
            }

            unsafe
            {
                fixed (byte* ptr = data)
                {

                    using (Bitmap image = new Bitmap(width, height, width * 4,
                                PixelFormat.Format32bppRgb, new IntPtr(ptr)))
                    {

                        image.Save(Path.ChangeExtension(fileName, ".jpg"));
                    }
                }
            }
        }

What about something like:

static inline double radians (double degrees) {return degrees * M_PI/180;}
UIImage* rotate(UIImage* src, UIImageOrientation orientation)
{
    UIGraphicsBeginImageContext(src.size);

    CGContextRef context = UIGraphicsGetCurrentContext();

    if (orientation == UIImageOrientationRight) {
        CGContextRotateCTM (context, radians(90));
    } else if (orientation == UIImageOrientationLeft) {
        CGContextRotateCTM (context, radians(-90));
    } else if (orientation == UIImageOrientationDown) {
        // NOTHING
    } else if (orientation == UIImageOrientationUp) {
        CGContextRotateCTM (context, radians(90));
    }

    [src drawAtPoint:CGPointMake(0, 0)];

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}

Use this command:

egrep -lRZ "\.jpg|\.png|\.gif" . \
    | xargs -0 -l sed -i -e 's/\.jpg\|\.gif\|\.png/.bmp/g'

• egrep: find matching lines using extended regular expressions

  • -l: only list matching filenames

  • -R: search recursively through all given directories

  • -Z: use \0 as record separator

  • "\.jpg|\.png|\.gif": match one of the strings ".jpg", ".gif" or ".png"

  • .: start the search in the current directory

• xargs: execute a command with the stdin as argument

  • -0: use \0 as record separator. This is important to match the -Z of egrep and to avoid being fooled by spaces and newlines in input filenames.

  • -l: use one line per command as parameter

• sed: the stream editor

  • -i: replace the input file with the output without making a backup

  • -e: use the following argument as expression

  • 's/\.jpg\|\.gif\|\.png/.bmp/g': replace all occurrences of the strings ".jpg", ".gif" or ".png" with ".bmp"

If you create a file in your repo named .gitignore git will use its rules when looking at files to commit. Note that git will not ignore a file that was already tracked before a rule was added to this file to ignore it. In such a case the file must be un-tracked, usually with :

git rm --cached filename

Is it your case ?

A combobox is unfortunately something that was left out of the HTML specifications.

The only way to manage it, rather unfortunately, is to roll your own or use a pre-built one. This one looks quite simple. I use this one for an open-source app although unfortunately you have to pay for commercial usage.

Since Typescript 2.0, @types npm modules are used to import typings.

# Implementation package (required to run)
$ npm install --save lodash

# Typescript Description
$ npm install --save @types/lodash 

Now since this question has been answered I'll go into how to efficiently import lodash

The failsafe way to import the entire library (in main.ts)

import 'lodash';

This is the new bit here:

Implementing a lighter lodash with the functions you require

import chain from "lodash/chain";
import value from "lodash/value";
import map from "lodash/map";
import mixin from "lodash/mixin";
import _ from "lodash/wrapperLodash";

PS: The above article is an interesting read on improving build time and reducing app size

You could also use:

$ mvn release:update-versions -DdevelopmentVersion={version}

to update the version numbers in your POMs.

I find that the timeout calls are not reliable enough in real life, particularly for internet explorer , however the following solutions may be of help:

1. You can timeout the complete test by using @Test(timeout=10000) in the junit test that you are running the selenium process from. This will free up the main thread for executing the other tests, instead of blocking up the whole show. However even this does not work at times.

2. Anyway by timing out you do not intend to salvage the test case, because timing out even a single operation might leave the entire test sequence in inconsistent state. You might just want to proceed with the other testcases without blocking (or perhaps retry the same test again). In such a case a fool-proof method would be to write a poller that polls processes of Webdriver (eg. IEDriverServer.exe, Phantomjs.exe) running for more than say 10 min and kill them. An example could be found at Automatically identify (and kill) processes with long processing time

An easy way without using collections

public void findHighestNoInArray() {
        int[] a = {1,2,6,8,9};
        int large = a[0];
            for(int num : a) {
                if(large < num) {
                    large = num;
                }
            }
            System.out.println("Large number is "+large+"");
        }

I had the same problem :) Verify the "Source code" folder on the "Solution Explorer", if it doesn't contain any "source code" file then :

Right click on "Source code" > Add > Existing Item > Choose the file You want to build and run.

Good luck ;)

I'm using Android 3.3 and that's how it worked for me:

1 - Choose the project view

2 - Right click the project name, which is in the root of the project and choose the option refactor -> copy, it will prompt you with a window to choose the new name.

3 - After step 2, Android will make a new project to you, you have to open that new project with the new name

4 - Change the name of the app in the "string.xml", it's in "app/res/values/string.xml"

Now you have it, the same project with a new name. Now you may want to change the name of the package, it's described on the followings steps

(optional) To change the name of the package main

5 - go to "app/java", there will be three folders with the same name, a main one, an (androidTest) and a (test), right click the main one and choose format -> rename, it will prompt you with a warning that multiple directories correspond to that package, then click "Rename package". Choose a new name and click in refactor. Now, bellow the code view, here will be a refactor preview, click in "Do refactor"

6 - Go to the option "build", click "Clean project", then "Rebuild project".

7 - Now close the project and reopen it again.

A terse solution using plain Javascript (thanks to Sygmoral for suggested improvements):

document.onkeydown = function(e) {
    switch (e.keyCode) {
        case 37:
            alert('left');
            break;
        case 39:
            alert('right');
            break;
    }
};

If your method is returning something back, you can solve this error by putting .Result to the end of the job and .Wait() if it doesn't return anything.

TL;DR: List.stream().forEach() was the fastest.

I felt I should add my results from benchmarking iteration. I took a very simple approach (no benchmarking frameworks) and benchmarked 5 different methods:

1. classic for
2. classic foreach
3. List.forEach()
4. List.stream().forEach()
5. List.parallelStream().forEach

the testing procedure and parameters

private List<Integer> list;
private final int size = 1_000_000;

public MyClass(){
    list = new ArrayList<>();
    Random rand = new Random();
    for (int i = 0; i < size; ++i) {
        list.add(rand.nextInt(size * 50));
    }    
}
private void doIt(Integer i) {
    i *= 2; //so it won't get JITed out
}

The list in this class shall be iterated over and have some doIt(Integer i) applied to all it's members, each time via a different method. in the Main class I run the tested method three times to warm up the JVM. I then run the test method 1000 times summing the time it takes for each iteration method (using System.nanoTime()). After that's done i divide that sum by 1000 and that's the result, average time. example:

myClass.fored();
myClass.fored();
myClass.fored();
for (int i = 0; i < reps; ++i) {
    begin = System.nanoTime();
    myClass.fored();
    end = System.nanoTime();
    nanoSum += end - begin;
}
System.out.println(nanoSum / reps);

I ran this on a i5 4 core CPU, with java version 1.8.0_05

classic for

for(int i = 0, l = list.size(); i < l; ++i) {
    doIt(list.get(i));
}

execution time: 4.21 ms

classic foreach

for(Integer i : list) {
    doIt(i);
}

execution time: 5.95 ms

List.forEach()

list.forEach((i) -> doIt(i));

execution time: 3.11 ms

List.stream().forEach()

list.stream().forEach((i) -> doIt(i));

execution time: 2.79 ms

List.parallelStream().forEach

list.parallelStream().forEach((i) -> doIt(i));

execution time: 3.6 ms

WWW FAQs: What is the maximum length of a URL? has its own answer based on empirical testing and research. The short answer is that going over 2048 characters makes Internet Explorer unhappy and thus this is the limit you should use. See the page for a long answer.

You can create an in-memory temporary table and store them in hive table using sqlContext.

Lets say your data frame is myDf. You can create one temporary table using,

myDf.createOrReplaceTempView("mytempTable") 

Then you can use a simple hive statement to create table and dump the data from your temp table.

sqlContext.sql("create table mytable as select * from mytempTable");

Under the Tools menu in Visual Studio 2008 (or 2005 if you have the right WCF stuff installed) there is an options called 'WCF Service Configuration Editor'.

From there you can change the binding options for both the client and the services, one of these options will be for time-outs.

Make sure you aren't using two versions of google service.

For example having:

compile 'com.google.firebase:firebase-messaging:9.8.0'

and

compile 'com.google.firebase:firebase-ads:10.0.0'

You can use ARG variable defaultValue and during the run command you can even update this value using --build-arg variable=value. To use these variables in the docker file you can refer them as $variable in run command.

Note: These variables would be available for Linux commands like RUN echo $variable and they wouldn't persist in the image.

Now, we need to handle it using following -

ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("chrome.switches", "--disable-extensions --disable-extensions-file-access-check --disable-extensions-http-throttling");

Apart from --disable-extensions, we also need to add --disable-extensions-file-access-check (and/or) --disable-extensions-http-throttling chrome switches.

It sounds like you are doing this on the main UI thread in the app. The UI thread is responsible for pumping windows messages as the arrive, and yet because yours is blocked in database calls it is unable to do so. This can cause problems with system wide messages.

You should look at spawning a background thread for the long running operation and putting up some kind of "I'm busy" dialog for the user while it happens.

You can do:

int[] data = {10,20,30,40,50,60,71,80,90,91};

You can also add items in code:

cboWhatever.Items.Add("SomeItem");

Also, to add something where you control display/value, (almost categorically needed in my experience) you can do so. I found a good stackoverflow reference here:

Key Value Pair Combobox in WPF

Sum-up code would be something like this:

ComboBox cboSomething = new ComboBox();
cboSomething.DisplayMemberPath = "Key";
cboSomething.SelectedValuePath = "Value";
cboSomething.Items.Add(new KeyValuePair<string, string>("Something", "WhyNot"));
cboSomething.Items.Add(new KeyValuePair<string, string>("Deus", "Why"));
cboSomething.Items.Add(new KeyValuePair<string, string>("Flirptidee", "Stuff"));
cboSomething.Items.Add(new KeyValuePair<string, string>("Fernum", "Blictor"));

You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:

https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899

buildUrls()

In this example, question 1, "Name", has an ID of 726721210, while question 2, "Birthday" is 787184751. Questions 3 and 4 are blank.

You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:

function buildUrls() {
  var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
  var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1");  // Email, Name, Birthday
  var data = ss.getDataRange().getValues();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    var url = template.replace('##Name##',escape(data[i][1]))
                      .replace('##Birthday##',data[i][2].yyyymmdd());  // see yyyymmdd below
    Logger.log(url);  // You could do something more useful here.
  }
};

This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.

betterBuildUrls()

Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.

Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0] is "Name", [1] is "Birthday", and so on.

We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.

(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)

/**
 * Use Form API to generate pre-filled form URLs
 */
function betterBuildUrls() {
  var ss = SpreadsheetApp.getActive();
  var sheet = ss.getSheetByName("Sheet1");
  var data = ss.getDataRange().getValues();  // Data for pre-fill

  var formUrl = ss.getFormUrl();             // Use form attached to sheet
  var form = FormApp.openByUrl(formUrl);
  var items = form.getItems();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    // Create a form response object, and prefill it
    var formResponse = form.createResponse();

    // Prefill Name
    var formItem = items[0].asTextItem();
    var response = formItem.createResponse(data[i][1]);
    formResponse.withItemResponse(response);

    // Prefill Birthday
    formItem = items[1].asDateItem();
    response = formItem.createResponse(data[i][2]);
    formResponse.withItemResponse(response);

    // Get prefilled form URL
    var url = formResponse.toPrefilledUrl();
    Logger.log(url);  // You could do something more useful here.
  }
};

yymmdd Function

Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd. This helper function extends the Date object with a new method to handle the conversion.

When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975 you could use 5/9/1975.)

// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
  var yyyy = this.getFullYear().toString();                                    
  var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based         
  var dd  = this.getDate().toString();             

  return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};

I would do this a little differently so that it scales without having to define every case:

select t.range as [score range], count(*) as [number of occurences]
from (
  select FLOOR(score/10) as range
  from scores) t
group by t.range

Not tested, but you get the idea...

The way to dynamically add elements to DOM, as explained on Angular 2 doc, is by using ViewContainerRef class from @Angular/core.

What you have to do is to declare a directive that will implement ViewContainerRef and act like a placeholder on your DOM.

Directive

import { Directive, ViewContainerRef } from '@angular/core';

@Directive({
  selector: '[appInject]'
})
export class InjectDirective {

  constructor(public viewContainerRef: ViewContainerRef) { }

}

Then, in the template where you want to inject the component:

HTML

<div class="where_you_want_to_inject">    
  <ng-template appInject></ng-template>
</div>

Then, from the injected component code, you will inject the component containing the HTML you want:

import { Component, OnInit, ViewChild, ComponentFactoryResolver } from '@angular/core';
import { InjectDirective } from '../inject.directive';
import { InjectedComponent } from '../injected/injected.component';

@Component({
  selector: 'app-parent',
  templateUrl: './parent.component.html',
  styleUrls: ['./parent.component.css']
})
export class ParentComponent implements OnInit {

  @ViewChild(InjectDirective) injectComp: InjectDirective;

  constructor(private _componentFactoryResolver: ComponentFactoryResolver) {
  }

You can use white-space: nowrap; to define this behaviour:

// HTML:

.nowrap {_x000D_
  white-space: nowrap ;_x000D_
}

<p>_x000D_
      <span class="nowrap">How do I wrap this line of text</span>_x000D_
      <span class="nowrap">- asked by Peter 2 days ago</span>_x000D_
    </p>

// CSS:
.nowrap {
  white-space: nowrap ;
}

If you have a 200,000,000 character files and split that every five characters, you have 40,000,000 String objects. Assume they are sharing actual character data with the original 400 MB String (char is 2 bytes). A String is say 32 bytes, so that is 1,280,000,000 bytes of String objects.

(It's probably worth noting that this is very implementation dependent. split could create entirely strings with entirely new backing char[] or, OTOH, share some common String values. Some Java implementations to not use the slicing of char[]. Some may use a UTF-8-like compact form and give very poor random access times.)

Even assuming longer strings, that's a lot of objects. With that much data, you probably want to work with most of it in compact form like the original (only with indexes). Only convert to objects that which you need. The implementation should be database like (although they traditionally don't handle variable length strings efficiently).

You can use the filter function to apply more complicated regex matching.

Here's an example which would just match the first three divs:

$('div')_x000D_
  .filter(function() {_x000D_
    return this.id.match(/abc+d/);_x000D_
  })_x000D_
  .html("Matched!");

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="abcd">Not matched</div>_x000D_
<div id="abccd">Not matched</div>_x000D_
<div id="abcccd">Not matched</div>_x000D_
<div id="abd">Not matched</div>

I literally striped out this line of code from content-single-popup.php located in woocommerce folder in my theme directory.

global $product; 
echo $product->get_categories( ', ', ' ' . _n( ' ', '  ', $cat_count, 'woocommerce' ) . ' ', ' ' );

Since my theme that I am working on has integrated woocommerce in it, this was my solution.

Put i++ somewhere at the end of your loop.

In the above code, the 0 position of the array is overwritten because i is not incremented in each loop.

FYI: the below is doing a redundant search:

if(keys[i].equals(DATE)){                 
   date_value[i] = map.get(keys[i]);              
} else if(keys[i].equals(VALUE)){              
   value_values[i] = map.get(keys[i]);             
} 

replace with

if(keys[i].equals(DATE)){                 
   date_value[i] = mapping.getValue();
} else if(keys[i].equals(VALUE)){              
   value_values[i] = mapping.getValue()
} 

Another issue is that you are using i for date_value and value_values. This is not valid unless you intend to have null values in your array.

POD in C++11 was basically split into two different axes here: triviality and layout. Triviality is about the relationship between an object's conceptual value and the bits of data within its storage. Layout is about... well, the layout of an object's subobjects. Only class types have layout, while all types have triviality relationships.

So here is what the triviality axis is about:

1. Non-trivially copyable: The value of objects of such types may be more than just the binary data that are stored directly within the object.

   For example, unique_ptr<T> stores a T*; that is the totality of the binary data within the object. But that's not the totality of the value of a unique_ptr<T>. A unique_ptr<T> stores either a nullptr or a pointer to an object whose lifetime is managed by the unique_ptr<T> instance. That management is part of the value of a unique_ptr<T>. And that value is not part of the binary data of the object; it is created by the various member functions of that object.

   For example, to assign nullptr to a unique_ptr<T> is to do more than just change the bits stored in the object. Such an assignment must destroy any object managed by the unique_ptr. To manipulate the internal storage of a unique_ptr without going through its member functions would damage this mechanism, to change its internal T* without destroying the object it currently manages, would violate the conceptual value that the object possesses.

2. Trivially copyable: The value of such objects are exactly and only the contents of their binary storage. This is what makes it reasonable to allow copying that binary storage to be equivalent to copying the object itself.

   The specific rules that define trivial copyability (trivial destructor, trivial/deleted copy/move constructors/assignment) are what is required for a type to be binary-value-only. An object's destructor can participate in defining the "value" of an object, as in the case with unique_ptr. If that destructor is trivial, then it doesn't participate in defining the object's value.

   Specialized copy/move operations also can participate in an object's value. unique_ptr's move constructor modifies the source of the move operation by null-ing it out. This is what ensures that the value of a unique_ptr is unique. Trivial copy/move operations mean that such object value shenanigans are not being played, so the object's value can only be the binary data it stores.

3. Trivial: This object is considered to have a functional value for any bits that it stores. Trivially copyable defines the meaning of the data store of an object as being just that data. But such types can still control how data gets there (to some extent). Such a type can have default member initializers and/or a default constructor that ensures that a particular member always has a particular value. And thus, the conceptual value of the object can be restricted to a subset of the binary data that it could store.

   Performing default initialization on a type that has a trivial default constructor will leave that object with completely uninitialized values. As such, a type with a trivial default constructor is logically valid with any binary data in its data storage.

The layout axis is really quite simple. Compilers are given a lot of leeway in deciding how the subobjects of a class are stored within the class's storage. However, there are some cases where this leeway is not necessary, and having more rigid ordering guarantees is useful.

Such types are standard layout types. And the C++ standard doesn't even really do much with saying what that layout is specifically. It basically says three things about standard layout types:

1. The first subobject is at the same address as the object itself.

2. You can use offsetof to get a byte offset from the outer object to one of its member subobjects.

3. unions get to play some games with accessing subobjects through an inactive member of a union if the active member is (at least partially) using the same layout as the inactive one being accessed.

Compilers generally permit standard layout objects to map to struct types with the same members in C. But there is no statement of that in the C++ standard; that's just what compilers feel like doing.

POD is basically a useless term at this point. It is just the intersection of trivial copyability (the value is only its binary data) and standard layout (the order of its subobjects is more well-defined). One can infer from such things that the type is C-like and could map to similar C objects. But the standard has no statements to that effect.

can you please elaborate following rules:

I'll try:

a) standard-layout classes must have all non-static data members with the same access control

That's simple: all non-static data members must all be public, private, or protected. You can't have some public and some private.

The reasoning for them goes to the reasoning for having a distinction between "standard layout" and "not standard layout" at all. Namely, to give the compiler the freedom to choose how to put things into memory. It's not just about vtable pointers.

Back when they standardized C++ in 98, they had to basically predict how people would implement it. While they had quite a bit of implementation experience with various flavors of C++, they weren't certain about things. So they decided to be cautious: give the compilers as much freedom as possible.

That's why the definition of POD in C++98 is so strict. It gave C++ compilers great latitude on member layout for most classes. Basically, POD types were intended to be special cases, something you specifically wrote for a reason.

When C++11 was being worked on, they had a lot more experience with compilers. And they realized that... C++ compiler writers are really lazy. They had all this freedom, but they didn't do anything with it.

The rules of standard layout are more or less codifying common practice: most compilers didn't really have to change much if anything at all to implement them (outside of maybe some stuff for the corresponding type traits).

Now, when it came to public/private, things are different. The freedom to reorder which members are public vs. private actually can matter to the compiler, particularly in debugging builds. And since the point of standard layout is that there is compatibility with other languages, you can't have the layout be different in debug vs. release.

Then there's the fact that it doesn't really hurt the user. If you're making an encapsulated class, odds are good that all of your data members will be private anyway. You generally don't expose public data members on fully encapsulated types. So this would only be a problem for those few users who do want to do that, who want that division.

So it's no big loss.

b) only one class in the whole inheritance tree can have non-static data members,

The reason for this one comes back to why they standardized standard layout again: common practice.

There's no common practice when it comes to having two members of an inheritance tree that actually store things. Some put the base class before the derived, others do it the other way. Which way do you order the members if they come from two base classes? And so on. Compilers diverge greatly on these questions.

Also, thanks to the zero/one/infinity rule, once you say you can have two classes with members, you can say as many as you want. This requires adding a lot of layout rules for how to handle this. You have to say how multiple inheritance works, which classes put their data before other classes, etc. That's a lot of rules, for very little material gain.

You can't make everything that doesn't have virtual functions and a default constructor standard layout.

and the first non-static data member cannot be of a base class type (this could break aliasing rules).

I can't really speak to this one. I'm not educated enough in C++'s aliasing rules to really understand it. But it has something to do with the fact that the base member will share the same address as the base class itself. That is:

struct Base {};
struct Derived : Base { Base b; };

Derived d;
static_cast<Base*>(&d) == &d.b;

And that's probably against C++'s aliasing rules. In some way.

However, consider this: how useful could having the ability to do this ever actually be? Since only one class can have non-static data members, then Derived must be that class (since it has a Base as a member). So Base must be empty (of data). And if Base is empty, as well as a base class... why have a data member of it at all?

Since Base is empty, it has no state. So any non-static member functions will do what they do based on their parameters, not their this pointer.

So again: no big loss.

I have a similar case: wanting my *.jar file to access a file in a directory next to said *.jar file. Refer to THIS ANSWER as well.

My file structure is:

./ - the root of your program
|__ *.jar
|__ dir-next-to-jar/some.txt

I'm able to load a file (say, some.txt) to an InputStream inside the *.jar file with the following:

InputStream stream = null;
    try{
        stream = ThisClassName.class.getClass().getResourceAsStream("/dir-next-to-jar/some.txt");
    }
    catch(Exception e) {
        System.out.print("error file to stream: ");
        System.out.println(e.getMessage());
    }

Then do whatever you will with the stream

As far as I can remember, an array is actually a group of pointers. For example

p[1]== *(&p+1)

is a true statement

Below is the code that implements custom vertical scrollbar. The important detail here is to know when scrollbar is needed by calculating how much space is consumed by the controls that you add to the panel.

panelUserInput.SuspendLayout();
panelUserInput.Controls.Clear();
panelUserInput.AutoScroll = false;
panelUserInput.VerticalScroll.Visible = false;

// here you'd be adding controls

int x = 20, y = 20, height = 0;
for (int inx = 0; inx < numControls; inx++ )
{
    // this example uses textbox control
    TextBox txt = new TextBox();
    txt.Location = new System.Drawing.Point(x, y);
    // add whatever details you need for this control
    // before adding it to the panel
    panelUserInput.Controls.Add(txt);
    height = y + txt.Height;
    y += 25;
}
if (height > panelUserInput.Height)
{
    VScrollBar bar = new VScrollBar();
    bar.Dock = DockStyle.Right;
    bar.Scroll += (sender, e) => { panelUserInput.VerticalScroll.Value =  bar.Value; };
    bar.Top = 0;
    bar.Left = panelUserInput.Width - bar.Width;
    bar.Height = panelUserInput.Height;
    bar.Visible = true;
    panelUserInput.Controls.Add(bar);
}
panelUserInput.ResumeLayout();

// then update the form
this.PerformLayout();

It means that trackDAO should not be serialized.

Groupby A:

In [0]: grp = df.groupby('A')

Within each group, sum over B and broadcast the values using transform. Then sort by B:

In [1]: grp[['B']].transform(sum).sort('B')
Out[1]:
          B
2 -2.829710
5 -2.829710
1  0.253651
4  0.253651
0  0.551377
3  0.551377

Index the original df by passing the index from above. This will re-order the A values by the aggregate sum of the B values:

In [2]: sort1 = df.ix[grp[['B']].transform(sum).sort('B').index]

In [3]: sort1
Out[3]:
     A         B      C
2  baz -0.528172  False
5  baz -2.301539   True
1  bar -0.611756   True
4  bar  0.865408  False
0  foo  1.624345  False
3  foo -1.072969   True

Finally, sort the 'C' values within groups of 'A' using the sort=False option to preserve the A sort order from step 1:

In [4]: f = lambda x: x.sort('C', ascending=False)

In [5]: sort2 = sort1.groupby('A', sort=False).apply(f)

In [6]: sort2
Out[6]:
         A         B      C
A
baz 5  baz -2.301539   True
    2  baz -0.528172  False
bar 1  bar -0.611756   True
    4  bar  0.865408  False
foo 3  foo -1.072969   True
    0  foo  1.624345  False

Clean up the df index by using reset_index with drop=True:

In [7]: sort2.reset_index(0, drop=True)
Out[7]:
     A         B      C
5  baz -2.301539   True
2  baz -0.528172  False
1  bar -0.611756   True
4  bar  0.865408  False
3  foo -1.072969   True
0  foo  1.624345  False

The return exits the current function, but the iterations keeps on, so you get the "next" item that skips the if and alerts the 4...

If you need to stop the looping, you should just use a plain for loop like so:

$('button').click(function () {
   var arr = [1, 2, 3, 4, 5];
   for(var i = 0; i < arr.length; i++) {
     var n = arr[i]; 
     if (n == 3) {
         break;
      }
      alert(n);
   })
})

int main(){
    ssize_t nrd;

    char* buffer = malloc(100*sizeof(char));
    fd = open("bli.txt", O_RDONLY);
    fd1 = open("bla.txt", O_CREAT | O_WRONLY, S_IRUSR | S_IWUSR);
    while (nrd = read(fd,buffer,sizeof(buffer))) {
        write(fd1,buffer,nrd);
    }   

    close(fd);
    close(fd1);
    free(buffer);
    return 0;
}

It is a tradition to use Turbo C for graphic in C/C++. But it’s also a pain in the neck. We are using Code::Blocks IDE, which will ease out our work.

Steps to run graphics code in CodeBlocks:

1. Install Code::Blocks
2. Download the required header files
3. Include graphics.h and winbgim.h
4. Include libbgi.a
5. Add Link Libraries in Linker Setting
6. include graphics.h and Save code in cpp extension

To test the setting copy paste run following code:

#include <graphics.h>
int main( )
{
    initwindow(400, 300, "First Sample");
    circle(100, 50, 40);
    while (!kbhit( ))
    {
        delay(200);
    }
    return 0;
}

Here is a complete setup instruction for Code::Blocks

How to include graphics.h in CodeBlocks?

You have to make a

if (i == null) {
   doSomething0();
} else {
   switch (i) {
   }
}

The best solution is to override the Django base.html template. Make another base.html template under admin directory. Make an admin directory first if it does not exist. app/admin/base.html.

Add {% block extrahead %} to the overriding template.

{% extends 'admin/base.html' %}
{% load staticfiles %}
{% block javascripts %}
    {{ block.super }}
<script type="text/javascript" src="{% static 'app/js/action.js' %}"></script>

{% endblock %}

{% block extrahead %}
    <link rel="shortcut icon" href="{% static 'app/img/favicon.ico'  %}" />
{% endblock %}
{% block stylesheets %}

    {{ block.super }}

UPDATE FOR VS CODE 1.40.0

After doing:

$ pip install pylint-django

Follow this link: https://code.visualstudio.com/docs/python/linting#_default-pylint-rules

Notice that the way to make pylint have into account pylint-django is by specifying:

"python.linting.pylintArgs": ["--load-plugins", "pylint_django"]

in the settings.json of VS Code.

But after that, you will notice a lot of new linting errors. Then, read what it said here:

These arguments are passed whenever the python.linting.pylintUseMinimalCheckers is set to true (the default). If you specify a value in pylintArgs or use a Pylint configuration file (see the next section), then pylintUseMinimalCheckers is implicitly set to false.

What I have done is creating a .pylintrc file as described in the link, and then, configured the following parameters inside the file (leaving the rest of the file untouched):

load-plugins=pylint_django

disable=all

enable=F,E,unreachable,duplicate-key,unnecessary-semicolon,global-variable-not-assigned,unused-variable,binary-op-exception,bad-format-string,anomalous-backslash-in-string,bad-open-mode

Now pylint works as expected.

In one line:

String niceFormattedJson = JsonWriter.formatJson(jsonString)

or

System.out.println(JsonWriter.formatJson(jsonString.toString()));

The json-io libray (https://github.com/jdereg/json-io) is a small (75K) library with no other dependencies than the JDK.

In addition to pretty-printing JSON, you can serialize Java objects (entire Java object graphs with cycles) to JSON, as well as read them in.

Update after I understand more how fragments work. Each fragment belongs to a parent activity. So just use:

getActivity().whatever

From within the fragment. It is a better answer because you avoid superflous casts. If you cannot avoid the casts with this solution use the one below.

============

what you have to do is to cast to the outer activity

((MainActivity) getActivity()).Method();

creating a new instance will be confusing the android frame and it will not be able to recognize it. see also :

According way you create your user, MySQL interprets a different manner. For instance, if you create a user like this:

create user user01 identified by 'test01';

MySQL expects you give some privilege using grant all on <your_db>.* to user01;

Don't forget to flush privileges;

But, if you create user like that (by passing an IP address), you have to change it to:

create user 'user02'@'localhost' identified by 'teste02';

so, to give some privileges you have to do that:

There are a new trick that no answer give. You can use printf instead NSLog. This will give you a clean log:

With NSLog you get things like this:

2011-11-03 13:43:55.632 myApp[3739:207] Hello Word

But with printf you get only:

Hello World

Use this code

#ifdef DEBUG
    #define NSLog(FORMAT, ...) fprintf(stderr,"%s\n", [[NSString stringWithFormat:FORMAT, ##__VA_ARGS__] UTF8String]);
#else
    #define NSLog(...) {}              
#endif

int p = 3; // fixed length padding
int n = 55; // number to test

string t = n.ToString("D" + p); // magic     

Console.WriteLine("Hello, world! >> {0}", t);

// outputs: 
// Hello, world! >> 055

You need to make your anchor display: block or display: inline-block; and then it will accept the width and height values.

FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
WindowState = FormWindowState.Maximized;

I Know, I am very late but, May be my answer can help someone. Basically it's very Simple. Here is my Code.

#include<iostream>
#include<windows.h>
using namespace std;
int main()
{
    HANDLE colors=GetStdHandle(STD_OUTPUT_HANDLE);

    string text;
    int k;
    cout<<" Enter your Text : ";
    getline(cin,text);
    for(int i=0;i<text.length();i++)
    {
        k>9 ? k=0 : k++;

        if(k==0)
        {
            SetConsoleTextAttribute(colors,1);
        }else
        {
            SetConsoleTextAttribute(colors,k);
        }
        cout<<text.at(i);
    }
}

OUTPUT

This Image will show you how it works

On Windows, you can use WMI (home page, cheeseshop):

def memory():
    import os
    from wmi import WMI
    w = WMI('.')
    result = w.query("SELECT WorkingSet FROM Win32_PerfRawData_PerfProc_Process WHERE IDProcess=%d" % os.getpid())
    return int(result[0].WorkingSet)

On Linux (from python cookbook http://code.activestate.com/recipes/286222/:

import os
_proc_status = '/proc/%d/status' % os.getpid()

_scale = {'kB': 1024.0, 'mB': 1024.0*1024.0,
          'KB': 1024.0, 'MB': 1024.0*1024.0}

def _VmB(VmKey):
    '''Private.
    '''
    global _proc_status, _scale
     # get pseudo file  /proc/<pid>/status
    try:
        t = open(_proc_status)
        v = t.read()
        t.close()
    except:
        return 0.0  # non-Linux?
     # get VmKey line e.g. 'VmRSS:  9999  kB\n ...'
    i = v.index(VmKey)
    v = v[i:].split(None, 3)  # whitespace
    if len(v) < 3:
        return 0.0  # invalid format?
     # convert Vm value to bytes
    return float(v[1]) * _scale[v[2]]


def memory(since=0.0):
    '''Return memory usage in bytes.
    '''
    return _VmB('VmSize:') - since


def resident(since=0.0):
    '''Return resident memory usage in bytes.
    '''
    return _VmB('VmRSS:') - since


def stacksize(since=0.0):
    '''Return stack size in bytes.
    '''
    return _VmB('VmStk:') - since

Being aware of the transaction (autocommit, explicit and implicit) handling for your database can save you from having to restore data from a backup.

Transactions control data manipulation statement(s) to ensure they are atomic. Being "atomic" means the transaction either occurs, or it does not. The only way to signal the completion of the transaction to database is by using either a COMMIT or ROLLBACK statement (per ANSI-92, which sadly did not include syntax for creating/beginning a transaction so it is vendor specific). COMMIT applies the changes (if any) made within the transaction. ROLLBACK disregards whatever actions took place within the transaction - highly desirable when an UPDATE/DELETE statement does something unintended.

Typically individual DML (Insert, Update, Delete) statements are performed in an autocommit transaction - they are committed as soon as the statement successfully completes. Which means there's no opportunity to roll back the database to the state prior to the statement having been run in cases like yours. When something goes wrong, the only restoration option available is to reconstruct the data from a backup (providing one exists). In MySQL, autocommit is on by default for InnoDB - MyISAM doesn't support transactions. It can be disabled by using:

SET autocommit = 0

An explicit transaction is when statement(s) are wrapped within an explicitly defined transaction code block - for MySQL, that's START TRANSACTION. It also requires an explicitly made COMMIT or ROLLBACK statement at the end of the transaction. Nested transactions is beyond the scope of this topic.

Implicit transactions are slightly different from explicit ones. Implicit transactions do not require explicity defining a transaction. However, like explicit transactions they require a COMMIT or ROLLBACK statement to be supplied.

Conclusion

Explicit transactions are the most ideal solution - they require a statement, COMMIT or ROLLBACK, to finalize the transaction, and what is happening is clearly stated for others to read should there be a need. Implicit transactions are OK if working with the database interactively, but COMMIT statements should only be specified once results have been tested & thoroughly determined to be valid.

That means you should use:

SET autocommit = 0;

START TRANSACTION;
  UPDATE ...;

...and only use COMMIT; when the results are correct.

That said, UPDATE and DELETE statements typically only return the number of rows affected, not specific details. Convert such statements into SELECT statements & review the results to ensure correctness prior to attempting the UPDATE/DELETE statement.

Addendum

DDL (Data Definition Language) statements are automatically committed - they do not require a COMMIT statement. IE: Table, index, stored procedure, database, and view creation or alteration statements.

Prefixing the string with an @ indicates that it should be treated as a literal, i.e. no escaping.

For example if your string contains a path you would typically do this:

string path = "c:\\mypath\\to\\myfile.txt";

The @ allows you to do this:

string path = @"c:\mypath\to\myfile.txt";

Notice the lack of double slashes (escaping)

I ran into this issue as well, but in order to use a safe pipe in my angular module, I installed the safe-pipe npm package, which you can find here. FYI, this worked in Angular 9.1.3, I haven't tried this in any other versions of Angular. Here's how you add it step by step:

1. Install the package via npm install safe-pipe or yarn add safe-pipe. This will store a reference to it in your dependencies in the package.json file, which you should already have from starting a new Angular project.

2. Add SafePipeModule module to NgModule.imports in your Angular module file like so:

   import { SafePipeModule } from 'safe-pipe';
   
   @NgModule({
       imports: [ SafePipeModule ]
   })
   export class AppModule { }
   
   

3. Add the safe pipe to an element in the template for the Angular component you are importing into your NgModule this way:

<element [property]="value | safe: sanitizationType"></element>

4. Here are some specific examples of the safePipe in an html element:

<div [style.background-image]="'url(' + pictureUrl + ')' | safe: 'style'" class="pic bg-pic"></div>
<img [src]="pictureUrl | safe: 'url'" class="pic" alt="Logo">
<iframe [src]="catVideoEmbed | safe: 'resourceUrl'" width="640" height="390"></iframe>
<pre [innerHTML]="htmlContent | safe: 'html'"></pre>

Here is how to use UIVibrancyEffect and UIBlurEffect with UIVisualEffectView

Objective-C:

// Blur effect
UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];
UIVisualEffectView *blurEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];
[blurEffectView setFrame:self.view.bounds];
[self.view addSubview:blurEffectView];

// Vibrancy effect
UIVibrancyEffect *vibrancyEffect = [UIVibrancyEffect effectForBlurEffect:blurEffect];
UIVisualEffectView *vibrancyEffectView = [[UIVisualEffectView alloc] initWithEffect:vibrancyEffect];
[vibrancyEffectView setFrame:self.view.bounds];

// Label for vibrant text
UILabel *vibrantLabel = [[UILabel alloc] init];
[vibrantLabel setText:@"Vibrant"];
[vibrantLabel setFont:[UIFont systemFontOfSize:72.0f]];
[vibrantLabel sizeToFit];
[vibrantLabel setCenter: self.view.center];

// Add label to the vibrancy view
[[vibrancyEffectView contentView] addSubview:vibrantLabel];

// Add the vibrancy view to the blur view
[[blurEffectView contentView] addSubview:vibrancyEffectView];

Swift 4:

    // Blur Effect
    let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.dark)
    let blurEffectView = UIVisualEffectView(effect: blurEffect)
    blurEffectView.frame = view.bounds
    view.addSubview(blurEffectView)

    // Vibrancy Effect
    let vibrancyEffect = UIVibrancyEffect(blurEffect: blurEffect)
    let vibrancyEffectView = UIVisualEffectView(effect: vibrancyEffect)
    vibrancyEffectView.frame = view.bounds

    // Label for vibrant text
    let vibrantLabel = UILabel()
    vibrantLabel.text = "Vibrant"
    vibrantLabel.font = UIFont.systemFont(ofSize: 72.0)
    vibrantLabel.sizeToFit()
    vibrantLabel.center = view.center

    // Add label to the vibrancy view
    vibrancyEffectView.contentView.addSubview(vibrantLabel)

    // Add the vibrancy view to the blur view
    blurEffectView.contentView.addSubview(vibrancyEffectView)

change the order of the functions fixed the problem for me:

• first Save the plot
• then Show the plot

as following:

plt.savefig('heatmap.png')

plt.show()

In my case I had Identity="ApplicationPoolIdentity" for my IIS Application Pool.

After I added IIS APPPOOL\ApplicationName user to SQL Server it works.

This is the correct way to handle max length on UITextField, it allows the return key to exit the resign the textfield as first responder and lets the user backspace when they reach the limit

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
int MAX_LENGHT = 5;
    if([string isEqualToString:@"\n"])
    {
        [textField resignFirstResponder];
        return FALSE;
    }
    else if(textField.text.length > MAX_LENGHT-1)
    {
        if([string isEqualToString:@""] && range.length == 1)
        {
            return TRUE;
        }
        else
        {
            return FALSE;
        }
    }
    else
    {
        return TRUE;
    }
}

This is also coming when you apply a constant in PHP to the empty() function:

if (!empty(SOME_CONSTANT)) {

}

That was my case. I solved it by using this:

$string = SOME_CONSTANT;
if (!empty($string)) {

}

I guess this is because your nodejs cert has expired. Type this line :
npm set registry http://registry.npmjs.org/
and after that try again with npm install . This actually solved my problem.

This can also be a issue when you enter wrong password for your sign key.

Here is the code that will open the SMS activity pre-populated with the phone number to which the SMS has to be sent. This works fine on emulator as well as the device.

Intent smsIntent = new Intent(Intent.ACTION_SENDTO);
smsIntent.addCategory(Intent.CATEGORY_DEFAULT);
smsIntent.setType("vnd.android-dir/mms-sms");
smsIntent.setData(Uri.parse("sms:" + phoneNumber));
startActivity(smsIntent);

XmlDocument xd = new XmlDocument();
xd.LoadXml(xmlContent);

context.Response.Clear();
context.Response.ContentType = "text/xml";
context.Response.ContentEncoding = System.Text.Encoding.UTF8;
xd.Save(context.Response.Output);
context.Response.Flush();
context.Response.SuppressContent = true;
context.ApplicationInstance.CompleteRequest();

With the latest version (2.8) of the Maven Dependency Plugin, downloading an artifact from the Maven Central Repository is as simple as:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=groupId:artifactId:version[:packaging[:classifier]]

where groupId:artifactId:version, etc. are the Maven coordinates

An example, tested with Maven 2.0.9, Maven 2.2.1, and Maven 3.0.4:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=org.hibernate:hibernate-entitymanager:3.4.0.GA:jar:sources

(Thanks to Pascal Thivent for providing his wonderful answer in the first place. I am adding another answer, because it wouldn't fit in a comment and it would be too extensive for an edit.)

In iOS8 sizeWithFont has been deprecated, please refer to

CGSize yourLabelSize = [yourLabel.text sizeWithAttributes:@{NSFontAttributeName : [UIFont fontWithName:yourLabel.font size:yourLabel.fontSize]}];

You can add all the attributes you want in sizeWithAttributes. Other attributes you can set:

- NSForegroundColorAttributeName
- NSParagraphStyleAttributeName
- NSBackgroundColorAttributeName
- NSShadowAttributeName

and so on. But probably you won't need the others

since PHP 5.4 you can use http_response_code() for get and set header status code.

here an example:

<?php

// Get the current response code and set a new one
var_dump(http_response_code(404));

// Get the new response code
var_dump(http_response_code());
?>

here is the document of this function in php.net:

http_response_code

You are not creating a separate dictionary for each iframe, you just keep modifying the same dictionary over and over, and you keep adding additional references to that dictionary in your list.

Remember, when you do something like content.append(info), you aren't making a copy of the data, you are simply appending a reference to the data.

You need to create a new dictionary for each iframe.

for iframe in soup.find_all('iframe'):
   info = {}
    ...

Even better, you don't need to create an empty dictionary first. Just create it all at once:

for iframe in soup.find_all('iframe'):
    info = {
        "src":    iframe.get('src'),
        "height": iframe.get('height'),
        "width":  iframe.get('width'),
    }
    content.append(info)

There are other ways to accomplish this, such as iterating over a list of attributes, or using list or dictionary comprehensions, but it's hard to improve upon the clarity of the above code.

Look at the PHP LDAP library functions: http://us.php.net/ldap.

Active Directory [mostly] conforms to the LDAP standard.

Unfortunately triggering the onsubmit or submit events wont work in all browsers.

• Works in IE and Chrome: #('form#ajaxForm')trigger('onsubmit');
• Works in Firefox and Safari: #('form#ajaxForm')trigger('submit');

Also, if you trigger('submit') in Chrome or IE, it causes the entire page to be posted rather than doing an AJAX behavior.

What works for all browsers is removing the onsubmit event behavior and just calling submit() on the form itself.

<script type="text/javascript">
$(function() {

    $('form#ajaxForm').submit(function(event) { 
        eval($(this).attr('onsubmit')); return false; 
        });

    $('form#ajaxForm').find('a.submit-link').click( function() { 
        $'form#ajaxForm').submit();
        });

  }
</script>
  <% using (Ajax.BeginForm("Update", "Description", new { id = Model.Id },
     new AjaxOptions
     {
       UpdateTargetId = "DescriptionDiv",
       HttpMethod = "post"
     }, new { id = "ajaxForm" } )) {%>
   Description:
   <%= Html.TextBox("Description", Model.Description) %><br />
   <a href="#" class="submit-link">Save</a> 
<% } %>

Also, the link doesn't have to be contained within the form in order for this to work.

You can check Announcing the official release of the Visual C++ Build Tools 2015 and from this blog, we can know that the Build Tools are the same C++ tools that you get with Visual Studio 2015 but they come in a scriptable standalone installer that only lays down the tools you need to build C++ projects. The Build Tools give you a way to install the tools you need on your build machines without the IDE you don’t need.

Because these components are the same as the ones installed by the Visual Studio 2015 Update 2 setup, you cannot install the Visual C++ Build Tools on a machine that already has Visual Studio 2015 installed. Therefore, it asks you to uninstall your existing VS 2015 when you tried to install the Visual C++ build tools using the standalone installer. Since you already have the VS 2015, you can go to Control Panel—Programs and Features and right click the VS 2015 item and Change-Modify, then check the option of those components that relates to the Visual C++ Build Tools, like Visual C++, Windows SDK… then install them. After the installation is successful, you can build the C++ projects.

Please try this Way And Let me know :

Context mContext;
@Override
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.neterrorlayout);

   mContext=NetErrorPage.this;
   Button reload=(Button)findViewById(R.id.btnReload);
   reload.setOnClickListener(this);    
   showInfoMessageDialog("Please check your network connection","Network Alert"); 
}
public void showInfoMessageDialog(String message,String title)
{
   new AlertDialog.Builder(mContext)
   .setTitle("Network Alert");
   .setMessage(message);
   .setButton("OK",new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog,int which) 
       {   
          dialog.cancel();
       }
   })
   .show();
}

Arrays can't be resized, so you need to allocte a new array that is larger, write the new byte at the beginning of it, and use Buffer.BlockCopy to transfer the contents of the old array across.

I know its quite late but for anyone looking to do it from now on, I hope this answer proves of some help. If you have CodeRush Express (free version, and a 'must have') installed, it offers a simple way to change a project wide namespace. You just place your cursor on the namespace that you want to change and it shall display a smart tag (a little blue box) underneath namespace string. You can either click that box or press Ctrl + keys to see the Rename option. Select it and then type in the new name for the project wide namespace, click Apply and select what places in your project you'd want it to change, in the new dialog and OK it. Done! :-)

Use a regular expression to catch the id number and replace the whole line with the number. Something like this should do it (match everything up to "id=", then match any number of digits, then match the rest of the line):

sed -e 's/.*id=\([0-9]\+\).*/\1/g'

Do this for every line and you get the list of ids.

The ready event is always execute at the only html page is loaded to the browser and the functions are executed.... But the load event is executed at the time of all the page contents are loaded to the browser for the page..... we can use $ or jQuery when we use the noconflict() method in jquery scripts...

My solution to find the first and last day of the current month:

def find_current_month_last_day(today: datetime) -> datetime:
    if today.month == 2:
        return today.replace(day=28)

    if today.month in [4, 6, 9, 11]:
        return today.replace(day=30)

    return today.replace(day=31)


def current_month_first_and_last_days() -> tuple:
    today = datetime.now().replace(hour=0, minute=0, second=0, microsecond=0)
    first_date = today.replace(day=1)
    last_date = find_current_month_last_day(today)
    return first_date, last_date

As Mentioned in above repilies:

Starting with MySQL 8.0.4, the MySQL team changed the default authentication plugin for MySQL server from mysql_native_password to caching_sha2_password.

So there are three ways to resolve this issue:

 1. drop USER 'user_name'@'localhost';
    flush privileges;
    CREATE USER 'user_name'@'localhost' IDENTIFIED BY 'user_name';
    GRANT ALL PRIVILEGES ON * . * TO 'user_name'@'localhost';
    ALTER USER 'user_name'@'localhost' IDENTIFIED WITH mysql_native_password BY 
    'user_name';

 2. drop USER 'user_name'@'localhost';
    flush privileges;
    CREATE USER 'user_name'@'localhost' IDENTIFIED WITH mysql_native_password BY 'user_name';
GRANT ALL PRIVILEGES ON * . * TO 'user_name'@'localhost'

 3. If the user is already created, the use the following command:

    ALTER USER 'user_name'@'localhost' IDENTIFIED WITH mysql_native_password BY 
        'user_name';

Why are you all going the hard way?

with open("myfile") as myfile:
    nonempty = filter(str.rstrip, myfile)

Convert nonempty into a list if you have the urge to do so, although I highly suggest keeping nonempty a generator as it is in Python 3.x

In Python 2.x you may use itertools.ifilter to do your bidding instead.

The answer is explained here.

To quote:

A class is free to implement comparison any way it chooses, and it can choose to make comparison against None mean something (which actually makes sense; if someone told you to implement the None object from scratch, how else would you get it to compare True against itself?).

Practically-speaking, there is not much difference since custom comparison operators are rare. But you should use is None as a general rule.

Convert a letter in hex code and hex code in letter.

        String letter = "a";
    String code;
    int decimal;

    code = Integer.toHexString(letter.charAt(0));
    decimal = Integer.parseInt(code, 16);

    System.out.println("Hex code to " + letter + " = " + code);
    System.out.println("Char to " + code + " = " + (char) decimal);
