Use like below:

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

}

You can do a post/get using a library which allows you to use HttpClient with strongly-typed callbacks.

The data and the error are available directly via these callbacks.

The library is called angular-extended-http-client.

angular-extended-http-client library on GitHub

angular-extended-http-client library on NPM

Very easy to use.

Traditional approach

In the traditional approach you return Observable<HttpResponse<T>> from Service API. This is tied to HttpResponse.

With this approach you have to use .subscribe(x => ...) in the rest of your code.

This creates a tight coupling between the http layer and the rest of your code.

Strongly-typed callback approach

You only deal with your Models in these strongly-typed callbacks.

Hence, The rest of your code only knows about your Models.

Sample usage

The strongly-typed callbacks are

Success:

• IObservable<T>
• IObservableHttpResponse
• IObservableHttpCustomResponse<T>

Failure:

• IObservableError<TError>
• IObservableHttpError
• IObservableHttpCustomError<TError>

Add package to your project and in your app module

import { HttpClientExtModule } from 'angular-extended-http-client';

and in the @NgModule imports

  imports: [
    .
    .
    .
    HttpClientExtModule
  ],

Your Models

export class SearchModel {
    code: string;
}

//Normal response returned by the API.
export class RacingResponse {
    result: RacingItem[];
}

//Custom exception thrown by the API.
export class APIException {
    className: string;
}

Your Service

In your Service, you just create params with these callback types.

Then, pass them on to the HttpClientExt's get method.

import { Injectable, Inject } from '@angular/core'
import { SearchModel, RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.

@Injectable()
export class RacingService {

    //Inject HttpClientExt component.
    constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {

    }

    //Declare params of type IObservable<T> and IObservableError<TError>.
    //These are the success and failure callbacks.
    //The success callback will return the response objects returned by the underlying HttpClient call.
    //The failure callback will return the error objects returned by the underlying HttpClient call.
    searchRaceInfo(model: SearchModel, success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
        let url = this.config.apiEndpoint;

        this.client.post<SearchModel, RacingResponse>(url, model, 
                                                      ResponseType.IObservable, success, 
                                                      ErrorType.IObservableError, failure);
    }
}

Your Component

In your Component, your Service is injected and the searchRaceInfo API called as shown below.

  search() {    


    this.service.searchRaceInfo(this.searchModel, response => this.result = response.result,
                                                  error => this.errorMsg = error.className);

  }

Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.

I found the solution as Its problem with Android Studio 3.1 Canary 6

My backup of Android Studio 3.1 Canary 5 is useful to me and saved my half day.

Now My build.gradle:

apply plugin: 'com.android.application'

and its working finally.

I think there problem in Android Studio 3.1 Canary 6

Thank you all for your time.

You have to look to official ReactiveX documentation: https://github.com/ReactiveX/rxjs/blob/master/doc/pipeable-operators.md.

This is a good article about piping in RxJS: https://blog.hackages.io/rxjs-5-5-piping-all-the-things-9d469d1b3f44.

In short .pipe() allows chaining multiple pipeable operators.

Starting in version 5.5 RxJS has shipped "pipeable operators" and renamed some operators:

do -> tap
catch -> catchError
switch -> switchAll
finally -> finalize

A POST with httpClient in Angular 6 was also doing an OPTIONS request:

Headers General:

Request URL:https://hp-probook/perl-bin/muziek.pl/=/postData
Request Method:OPTIONS
Status Code:200 OK
Remote Address:127.0.0.1:443
Referrer Policy:no-referrer-when-downgrade

My Perl REST server implements the OPTIONS request with return code 200.

The next POST request Header:

Accept:*/*
Accept-Encoding:gzip, deflate, br
Accept-Language:nl-NL,nl;q=0.8,en-US;q=0.6,en;q=0.4
Access-Control-Request-Headers:content-type
Access-Control-Request-Method:POST
Connection:keep-alive
Host:hp-probook
Origin:http://localhost:4200
Referer:http://localhost:4200/
User-Agent:Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.109 Safari/537.36

Notice Access-Control-Request-Headers:content-type.

So, my backend perl script uses the following headers:

 -"Access-Control-Allow-Origin" => '*',
 -"Access-Control-Allow-Methods" => 'GET,POST,PATCH,DELETE,PUT,OPTIONS',
 -"Access-Control-Allow-Headers" => 'Origin, Content-Type, X-Auth-Token, content-type',

With this setup the GET and POST worked for me!

For future visitors: In the new HttpClient (Angular 4.3+), the response object is JSON by default, so you don't need to do response.json().data anymore. Just use response directly.

Example (modified from the official documentation):

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

@Component(...)
export class YourComponent implements OnInit {

  // Inject HttpClient into your component or service.
  constructor(private http: HttpClient) {}

  ngOnInit(): void {
    this.http.get('https://api.github.com/users')
        .subscribe(response => console.log(response));
  }
}

Don't forget to import it and include the module under imports in your project's app.module.ts:

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

@NgModule({
  imports: [
    BrowserModule,
    // Include it under 'imports' in your application module after BrowserModule.
    HttpClientModule,
    ...
  ],
  ...

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).

In your HTML code

<form [formGroup]="userForm">
    <input type="text" class="form-control"  [value]="item.UserFirstName" formControlName="UserFirstName">
    <input type="text" class="form-control"  [value]="item.UserLastName" formControlName="UserLastName">
</form>

In your Typescript code

export class UserprofileComponent implements OnInit {
    userForm: FormGroup;
    constructor(){ 
       this.userForm = new FormGroup({
          UserFirstName: new FormControl(),
          UserLastName: new FormControl()
       });
    }
}

This works perfectly, it does not give any error.

As the error messages stated, ngFor only supports Iterables such as Array, so you cannot use it for Object.

change

private extractData(res: Response) {
  let body = <Afdelingen[]>res.json();
  return body || {};       // here you are return an object
}

to

private extractData(res: Response) {
  let body = <Afdelingen[]>res.json().afdelingen;    // return array from json file
  return body || [];     // also return empty array if there is no data
}

if someone facing issue of CORS not working in mobile browser or mobile applications, you can set ALLOWED_HOSTS = ["your host ip"] in backend servers where your rest api exists, here your host ip is external ip to access ionic , like External: http://192.168.1.120:8100

After that in ionic type script make post or get using IP of backened server

in my case i used django rest framwork and i started server as:- python manage.py runserver 192.168.1.120:8000

and used this ip in ionic get and post calls of rest api

While integrating material dialog is possible, I found that the complexity for such a trivial feature is pretty high. The code gets more complex if you are trying to achieve a non-trivial features.

For that reason, I ended up using PrimeNG Dialog, which I found pretty straightforward to use:

m-dialog.component.html:

<p-dialog header="Title">
  Content
</p-dialog>

m-dialog.component.ts:

@Component({
  selector: 'm-dialog',
  templateUrl: 'm-dialog.component.html',
  styleUrls: ['./m-dialog.component.css']
})
export class MDialogComponent {
  // dialog logic here
}

m-dialog.module.ts:

import { NgModule } from "@angular/core";
import { CommonModule } from "@angular/common";
import { DialogModule } from "primeng/primeng";
import { FormsModule } from "@angular/forms";

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    DialogModule
  ], 
  exports: [
    MDialogComponent,
  ], 
  declarations: [
    MDialogComponent
  ]
})
export class MDialogModule {}

Simply add your dialog into your component's html:

<m-dialog [isVisible]="true"> </m-dialog>

PrimeNG PrimeFaces documentation is easy to follow and very precise.

For us we used a solution like this:

this.http.get(this.urls.order + '&list', {
        headers: {
            'Cache-Control': 'no-cache',
        }
    }).subscribe((response) => { ...

Reference here

I have observed the same behavior during test execution. It is strange that on production code works fine and fails only on tests.

Easy solution to make your tests happy is to add catch(angular.noop) to your promise mock. In case of example above it should looks like this:

resourceMock.get = function () {_x000D_
    var deferred = $q.defer();_x000D_
    deferred.reject(error);_x000D_
    return { $promise: deferred.promise.catch(angular.noop) };_x000D_
};

Take a look at your code :

 getUsers(): Observable<User[]> {
        return Observable.create(observer => {
            this.http.get('http://users.org').map(response => response.json();
        })
    }

and code from https://angular.io/docs/ts/latest/tutorial/toh-pt6.html (BTW. really good tutorial, you should check it out)

 getHeroes(): Promise<Hero[]> {
    return this.http.get(this.heroesUrl)
               .toPromise()
               .then(response => response.json().data as Hero[])
               .catch(this.handleError);
  }

The HttpService inside Angular2 already returns an observable, sou don't need to wrap another Observable around like you did here:

   return Observable.create(observer => {
        this.http.get('http://users.org').map(response => response.json()

Try to follow the guide in link that I provided. You should be just fine when you study it carefully.

---EDIT----

First of all WHERE you log the this.users variable? JavaScript isn't working that way. Your variable is undefined and it's fine, becuase of the code execution order!

Try to do it like this:

  getUsers(): void {
        this.userService.getUsers()
            .then(users => {
               this.users = users
               console.log('this.users=' + this.users);
            });


    }

See where the console.log(...) is!

Try to resign from toPromise() it's seems to be just for ppl with no RxJs background.

Catch another link: https://scotch.io/tutorials/angular-2-http-requests-with-observables Build your service once again with RxJs observables.

In your product.service.ts you are using stringify method in a wrong way..

Just use

JSON.stringify(product) 

instead of

JSON.stringify({product})

i have checked your problem and after this it's working absolutely fine.

Here is my POST method with HTTPS which returns a response body for any type of bad responses.

public String postHTTPSRequest(String url,String requestJson)
{
    //SSL Context
    CloseableHttpClient httpClient = HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier()).build();
    HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
    requestFactory.setHttpClient(httpClient);
    //Initiate REST Template
    RestTemplate restTemplate = new RestTemplate(requestFactory);
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    //Send the Request and get the response.
    HttpEntity<String> entity = new HttpEntity<String>(requestJson,headers);
    ResponseEntity<String> response;
    String stringResponse = "";
    try {
        response = restTemplate.postForEntity(url, entity, String.class);
        stringResponse = response.getBody();
    }
    catch (HttpClientErrorException e)
    {
        stringResponse = e.getResponseBodyAsString();
    }
    return stringResponse;
}

This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    } 

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.

In angular 8:

//for catch:
import { catchError } from 'rxjs/operators';

//for throw:
import { Observable, throwError } from 'rxjs';

//and code should be written like this.

getEmployees(): Observable<IEmployee[]> {
    return this.http.get<IEmployee[]>(this.url).pipe(catchError(this.erroHandler));
  }

  erroHandler(error: HttpErrorResponse) {
    return throwError(error.message || 'server Error');
  }

The RxJS functions need to be specifically imported. An easy way to do this is to import all of its features with import * as Rx from "rxjs/Rx"

Then make sure to access the Observable class as Rx.Observable.

I think the Key and IV used for encryption using command line and decryption using your program are not same.

Please note that when you use the "-k" (different from "-K"), the input given is considered as a password from which the key is derived. Generally in this case, there is no need for the "-iv" option as both key and password will be derived from the input given with "-k" option.

It is not clear from your question, how you are ensuring that the Key and IV are same between encryption and decryption.

In my suggestion, better use "-K" and "-iv" option to explicitly specify the Key and IV during encryption and use the same for decryption. If you need to use "-k", then use the "-p" option to print the key and iv used for encryption and use the same in your decryption program.

More details can be obtained at https://www.openssl.org/docs/manmaster/apps/enc.html

Add an onChange handler to each of your TextField and DropDownMenu elements. When it is called, save the new value of these inputs in the state of your Content component. In render, retrieve these values from state and pass them as the value prop. See Controlled Components.

var Content = React.createClass({

    getInitialState: function() {
        return {
            textFieldValue: ''
        };
    },

    _handleTextFieldChange: function(e) {
        this.setState({
            textFieldValue: e.target.value
        });
    },

    render: function() {
        return (
            <div>
                <TextField value={this.state.textFieldValue} onChange={this._handleTextFieldChange} />
            </div>
        )
    }

});

Now all you have to do in your _handleClick method is retrieve the values of all your inputs from this.state and send them to the server.

You can also use the React.addons.LinkedStateMixin to make this process easier. See Two-Way Binding Helpers. The previous code becomes:

var Content = React.createClass({

    mixins: [React.addons.LinkedStateMixin],

    getInitialState: function() {
        return {
            textFieldValue: ''
        };
    },

    render: function() {
        return (
            <div>
                <TextField valueLink={this.linkState('textFieldValue')} />
            </div>
        )
    }

});

MongoDB shell version v4.2.6
Node v14.2.0

Assuming you have a Tour Model: tourModel.js

const mongoose = require('mongoose');

const tourSchema = new mongoose.Schema({
  name: {
    type: String,
    required: [true, 'A tour must have a name'],
    unique: true,
    trim: true,
  },
  createdAt: {
    type: Date,
    default: Date.now(),
  },
});
const Tour = mongoose.model('Tour', tourSchema);

module.exports = Tour;

Now you want to delete all tours at once from your MongoDB, I also providing connection code to connect with the remote cluster. I used deleteMany(), if you do not pass any args to deleteMany(), then it will delete all the documents in Tour collection.

const mongoose = require('mongoose');
const Tour = require('./../../models/tourModel');
const conStr = 'mongodb+srv://lord:<PASSWORD>@cluster0-eeev8.mongodb.net/tour-guide?retryWrites=true&w=majority';
const DB = conStr.replace('<PASSWORD>','ADUSsaZEKESKZX');
mongoose.connect(DB, {
    useNewUrlParser: true,
    useCreateIndex: true,
    useFindAndModify: false,
    useUnifiedTopology: true,
  })
  .then((con) => {
    console.log(`DB connection successful ${con.path}`);
  });

const deleteAllData = async () => {
  try {
    await Tour.deleteMany();
    console.log('All Data successfully deleted');
  } catch (err) {
    console.log(err);
  }
};

I found that this problem happened to me and to a colleague after changing the name of our solution/project.

The issue resulting from my colleague: I pulled changes into my branch and had the error. In my bin folder I found the old .dll files sitting with the newly named .dll files. Deleted the old ones and the problem went away.

I wasn't using Azure, but I got the same error locally. Using <customErrors mode="Off" /> seemed to have no effect, but checking the Application logs in Event Viewer revealed a warning from ASP.NET which contained all the detail I needed to resolve the issue.

You can get errors working correctly without hacking global.cs, messing with HandleErrorAttribute, doing Response.TrySkipIisCustomErrors, hooking up Application_Error, or whatever:

In system.web (just the usual, on/off)

<customErrors mode="On">
  <error redirect="/error/401" statusCode="401" />
  <error redirect="/error/500" statusCode="500" />
</customErrors>

and in system.webServer

<httpErrors existingResponse="PassThrough" />

Now things should behave as expected, and you can use your ErrorController to display whatever you need.

I was getting this on an asp.net 2.0 iis7 Windows2008 site. Same code on iis6 worked fine. It was causing an issue for me because it was messing up the login process. User would login and get a 302 to default.asxp, which would get through page_load, but not as far as pre-render before iis7 would send a 302 back to login.aspx without the auth cookie. I started playing with app pool settings, and for some reason 'enable 32 bit applications' seems to have fixed it. No idea why, since this site isn't doing anything special that should require any 32 bit drivers. We have some sites that still use Access that require 32bit, but not our straight SQL sites like this one.

This is not exactly the answer to the question, but I end up here every time I want to find out how to get my batch file to exit with and error code when a process returns an nonzero code.

So here is the answer to that:

if %ERRORLEVEL% NEQ 0 exit %ERRORLEVEL%

Check whether your phone supports the video format or not.Even I had the problem when playing a 3gp file but it played a mp4 file perfectly.

Just to add to the responses above. I had this same issue when i first started using ASP.Net MVC and i was doing a Response.Redirect during a controller action:

Response.Redirect("/blah", true);

Instead of returning a Response.Redirect action i should have been returning a RedirectAction:

return Redirect("/blah");

Phil Haak has an example that I think is a bit more stable when dealing with paths with crazy "\" style directory separators. It also safely handles path concatenation. It comes for free in System.IO

var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);

However, you could also try "AppDomain.CurrentDomain.BaseDirector" instead of "Server.MapPath".

For me it was very important to get email logging working. After some time I discover that this need only 2 lines of code more in Atif example.

Add Validate Connection=true to your connection string.

Look at this blog to find more about.

DETAILS: After OracleConnection.Close() the real database connection does not terminate. The connection object is put back in connection pool. The use of connection pool is implicit by ODP.NET. If you create a new connection you get one of the pool. If this connection is "yet open" the OracleConnection.Open() method does not really creates a new connection. If the real connection is broken (for any reason) you get a failure on first select, update, insert or delete.

With Validate Connection the real connection is validated in Open() method.

To Change Button title:

[mybtn setTitle:@"My Button" forState:UIControlStateNormal];
[mybtn setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];

For Disable:

[mybtn setEnabled:NO];

<project name="Build" basedir="." default="clean">
    <property name="default.build.type" value ="Release"/>

    <target name="clean">
    <echo>Value Buld is now  ${PARAM_BUILD_TYPE} is set</echo>
        <condition property="build.type" value="${PARAM_BUILD_TYPE}" else="${default.build.type}">
            <isset property="PARAM_BUILD_TYPE"/>
        </condition>

       <echo>Value Buld is now  ${PARAM_BUILD_TYPE} is set</echo>
       <echo>Value Buld is now  ${build.type} is set</echo>
    </target>
</project>

In my Case DPARAM_BUILD_TYPE=Debug if it is supplied than, I need to build for for Debug otherwise i need to go for building Release build. I write like above condition it worked and i have tested as below it is working fine for me.

And property ${build.type} we can pass this to other target or macrodef for processing which i am doing in my other ant macrodef.

D:\>ant -DPARAM_BUILD_TYPE=Debug
Buildfile: D:\build.xml
clean:
     [echo] Value Buld is now  Debug is set
     [echo] Value Buld is now  Debug is set
     [echo] Value Buld is now  Debug is set
main:
BUILD SUCCESSFUL
Total time: 0 seconds
D:\>ant
Buildfile: D:\build.xml
clean:
     [echo] Value Buld is now  ${PARAM_BUILD_TYPE} is set
     [echo] Value Buld is now  ${PARAM_BUILD_TYPE} is set
     [echo] Value Buld is now  Release is set
main:
BUILD SUCCESSFUL
Total time: 0 seconds

It work for me to implement condition so posted hope it will helpful.

In your case you would use two case staements, one for each value you want returned.

The short answer

Many of the answers here rely on the widely-used mathematical definition [1]:

• Discriminative models directly learn the conditional predictive distribution p(y|x).
• Generative models learn the joint distribution p(x,y) (or rather, p(x|y) and p(y)).
  • Predictive distribution p(y|x) can be obtained with Bayes' rule.

Although very useful, this narrow definition assumes the supervised setting, and is less handy when examining unsupervised or semi-supervised methods. It also doesn't apply to many contemporary approaches for deep generative modeling. For example, now we have implicit generative models, e.g. Generative Adversarial Networks (GANs), which are sampling-based and don't even explicitly model the probability density p(x) (instead learning a divergence measure via the discriminator network). But we call them "generative models” since they are used to generate (high-dimensional [10]) samples.

A broader and more fundamental definition [2] seems equally fitting for this general question:

• Discriminative models learn the boundary between classes.
  • So they can discriminate between different kinds of data instances.
• Generative models learn the distribution of data.
  • So they can generate new data instances.

A closer look

Even so, this question implies somewhat of a false dichotomy [3]. The generative-discriminative "dichotomy" is in fact a spectrum which you can even smoothly interpolate between [4].

As a consequence, this distinction gets arbitrary and confusing, especially when many popular models do not neatly fall into one or the other [5,6], or are in fact hybrid models (combinations of classically "discriminative" and "generative" models).

Nevertheless it's still a highly useful and common distinction to make. We can list some clear-cut examples of generative and discriminative models, both canonical and recent:

• Generative: Naive Bayes, latent Dirichlet allocation (LDA), Generative Adversarial Networks (GAN), Variational Autoencoders (VAE), normalizing flows.
• Discriminative: Support vector machine (SVM), logistic regression, most deep neural networks.

There is also a lot of interesting work deeply examining the generative-discriminative divide [7] and spectrum [4,8], and even transforming discriminative models into generative models [9].

In the end, definitions are constantly evolving, especially in this rapidly growing field :) It's best to take them with a pinch of salt, and maybe even redefine them for yourself and others.

Python lists (which are not just arrays because their size can be changed on the fly) are normal Python objects and can be passed in to functions as any variable. The * syntax is used for unpacking lists, which is probably not something you want to do now.

When I had this problem I've done it from command line:

zip file.zip uncompressed

EDIT, after many downvotes: I was using this option for some time ago and I don't know where I learnt it, so I can't give you a better explanation. Chris Johnson's answer is correct, but I won't delete mine. As one comment says, it's more accurate to what OP is asking, as it compress without those files, instead of removing them from a compressed file. I find it easier to remember, too.

You can also use:

$(window).bind("load", function() { 
    // Your code here.
});

Options A, B and D seem to be in the same category since they only influence the initial start time, they do warmup of the website like compilation and loading of libraries in memory.

Using C, setting the idle timeout, should be enough so that subsequent requests to the server are served fast (restarting the app pool takes quite some time - in the order of seconds).

As far as I know, the timeout exists to save memory that other websites running in parallel on that machine might need. The price being that one time slow load time.

Besides the fact that the app pool gets shutdown in case of user inactivity, the app pool will also recycle by default every 1740 minutes (29 hours).

From technet:

Internet Information Services (IIS) application pools can be periodically recycled to avoid unstable states that can lead to application crashes, hangs, or memory leaks.

As long as app pool recycling is left on, it should be enough. But if you really want top notch performance for most components, you should also use something like the Application Initialization Module you mentioned.

here's the way I've used, it's working for negative number

First, create MinMaxFIlter.java class with the following code :

import android.text.InputFilter;
import android.text.Spanned;
import android.util.Log;

/**
* Created by 21 on 4/5/2016.
*/
public class MinMaxFilter implements InputFilter {

private double mIntMin, mIntMax;

public MinMaxFilter(double minValue, double maxValue) {
    this.mIntMin = minValue;
    this.mIntMax = maxValue;
}

public MinMaxFilter(String minValue, String maxValue) {
    this.mIntMin = Double.parseDouble(minValue);
    this.mIntMax = Double.parseDouble(maxValue);
}

@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
    try {
        Boolean isNeg = false;
        String provi = dest.toString() + source.toString();
        if("-".equals(provi.substring(0,1))){
            if(provi.length()>1) {
                provi = provi.substring(1, provi.length());
                isNeg = true;
            }
            else{
                if("".equals(source)){
                    return null;
                }
                return "-";
            }
        }

        double input = Double.parseDouble(provi); 
        if(isNeg){input = input * (-1);}

        if (isInRange(mIntMin, mIntMax, input)) {
            return null;
        }
    } catch (Exception nfe) {}
    return "";
}

private boolean isInRange(double a, double b, double c) {
    if((c>=a && c<=b)){
        return true;
    }
    else{
        return false;
    }
}
}

Then, create and set your filter to your edittext like this :

EditText edittext = new EditText(context);
editext.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_SIGNED);
eInt.setFilters(new InputFilter[]{new MinMaxFilter(min, max)});

Update: Sep 2019

As a few people have mentioned, the parameters in paramMap should be accessed using the common MapAPI:

To get a snapshot of the params, when you don't care that they may change:

this.bankName = this.route.snapshot.paramMap.get('bank');

To subscribe and be alerted to changes in the parameter values (typically as a result of the router's navigation)

this.route.paramMap.subscribe( paramMap => {
    this.bankName = paramMap.get('bank');
})

Update: Aug 2017

Since Angular 4, params have been deprecated in favor of the new interface paramMap. The code for the problem above should work if you simply substitute one for the other.

Original Answer

If you inject ActivatedRoute in your component, you'll be able to extract the route parameters

    import {ActivatedRoute} from '@angular/router';
    ...
    
    constructor(private route:ActivatedRoute){}
    bankName:string;
    
    ngOnInit(){
        // 'bank' is the name of the route parameter
        this.bankName = this.route.snapshot.params['bank'];
    }

If you expect users to navigate from bank to bank directly, without navigating to another component first, you ought to access the parameter through an observable:

    ngOnInit(){
        this.route.params.subscribe( params =>
            this.bankName = params['bank'];
        )
    }

For the docs, including the differences between the two check out this link and search for "activatedroute"

Another possible answer considering also the case that an empty string might contain several whitespace characters for example spaces,tabs,line break characters can be the folllowing pattern.

pattern = r"^(\s*)$"

This pattern matches if the string starts and ends with zero or more whitespace characters.

It was tested in Python 3

I have seen many answers to this question and found some answer is lengthy and some answer is a little bit wrong. I have created my own code by using the above IDs and class.

$('#ckbCheckAll').click(function(){
        if($(this).prop("checked")) {
            $(".checkBoxClass").prop("checked", true);
        } else {
            $(".checkBoxClass").prop("checked", false);
        }                
    });


    $('.checkBoxClass').click(function(){
        if($(".checkBoxClass").length == $(".checkBoxClass:checked").length) { 
            $("#ckbCheckAll").prop("checked", true);
        }else {
            $("#ckbCheckAll").prop("checked", false);            
        }
    });

In the above code, where user clicks on select all checkbox and all checkbox will be selected and vice versa and second code will work when the user selects checkbox one by one then select all checkbox will be checked or unchecked according to a number of checkboxes checked.

In your code, try enclosing password inside single quote. Alternatively, as per the documentation of mysql, following should work -

SET PASSWORD FOR 'jeffrey'@'localhost' = PASSWORD('cleartext password');

FLUSH PRIVILEGES;

The last line is important or else your password change won't take effect unfortunately.

EDIT:

I ran a test in my local and it worked -

mysql>  set password for 'test' = PASSWORD('$w0rdf1sh');
Query OK, 0 rows affected (0.00 sec)

Mine is version 5. You can use following command to determine your version -

SHOW VARIABLES LIKE "%version%";

1. mv your folder app to make backup, i.e. mv app_folder app_folder_bk (it is like a git stash)
2. git clone your_repository
3. Finally,. Open a merge tool (I use meld diff viewer linux or Winmerge Windows) and copy the changes from right(app_folder_bk) to left( new app_folder) (it is like a git stash apply).

That's all. Maybe it is not the best way, but I think it is so practical .

Regan's answer is great, but it's a bit out of date, since the correct way to do this is avoid the lxc execution context as Docker has dropped LXC as the default execution context as of docker 0.9.

Instead it's better to tell docker about the nvidia devices via the --device flag, and just use the native execution context rather than lxc.

Environment

These instructions were tested on the following environment:

• Ubuntu 14.04
• CUDA 6.5
• AWS GPU instance.

Install nvidia driver and cuda on your host

See CUDA 6.5 on AWS GPU Instance Running Ubuntu 14.04 to get your host machine setup.

Install Docker

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
$ sudo sh -c "echo deb https://get.docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
$ sudo apt-get update && sudo apt-get install lxc-docker

Find your nvidia devices

ls -la /dev | grep nvidia

crw-rw-rw-  1 root root    195,   0 Oct 25 19:37 nvidia0 
crw-rw-rw-  1 root root    195, 255 Oct 25 19:37 nvidiactl
crw-rw-rw-  1 root root    251,   0 Oct 25 19:37 nvidia-uvm

Run Docker container with nvidia driver pre-installed

I've created a docker image that has the cuda drivers pre-installed. The dockerfile is available on dockerhub if you want to know how this image was built.

You'll want to customize this command to match your nvidia devices. Here's what worked for me:

 $ sudo docker run -ti --device /dev/nvidia0:/dev/nvidia0 --device /dev/nvidiactl:/dev/nvidiactl --device /dev/nvidia-uvm:/dev/nvidia-uvm tleyden5iwx/ubuntu-cuda /bin/bash

Verify CUDA is correctly installed

This should be run from inside the docker container you just launched.

Install CUDA samples:

$ cd /opt/nvidia_installers
$ ./cuda-samples-linux-6.5.14-18745345.run -noprompt -cudaprefix=/usr/local/cuda-6.5/

Build deviceQuery sample:

$ cd /usr/local/cuda/samples/1_Utilities/deviceQuery
$ make
$ ./deviceQuery   

If everything worked, you should see the following output:

deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 6.5, CUDA Runtime Version = 6.5, NumDevs =    1, Device0 = GRID K520
Result = PASS

Since PHP 5.6, a variable argument list can be specified with the ... operator.

function do_something($first, ...$all_the_others)
{
    var_dump($first);
    var_dump($all_the_others);
}

do_something('this goes in first', 2, 3, 4, 5);

#> string(18) "this goes in first"
#>
#> array(4) {
#>   [0]=>
#>   int(2)
#>   [1]=>
#>   int(3)
#>   [2]=>
#>   int(4)
#>   [3]=>
#>   int(5)
#> }

As you can see, the ... operator collects the variable list of arguments in an array.

If you need to pass the variable arguments to another function, the ... can still help you.

function do_something($first, ...$all_the_others)
{
    do_something_else($first, ...$all_the_others);
    // Which is translated to:
    // do_something_else('this goes in first', 2, 3, 4, 5);
}

Since PHP 7, the variable list of arguments can be forced to be all of the same type too.

function do_something($first, int ...$all_the_others) { /**/ }

This method will prevent you from getting an 'Access-Control-Allow-Origin' error from the server you are accessing to.

var img = new Image();
var timestamp = new Date().getTime();
img.setAttribute('crossOrigin', 'anonymous');
img.src = url + '?' + timestamp;

Official Microsoft docs for for command

This post really helped me to finally get what I want. So I just wanted to contribute my code here to help others. Here is my code with some explanation.

The following code:

double moneyWithDecimals = 5.50;
double moneyNoDecimals = 5.00;
System.out.println(jeroensFormat(moneyWithDecimals));
System.out.println(jeroensFormat(moneyNoDecimals));

Will return:

€ 5,-
€ 5,50

The actual jeroensFormat() method:

public String jeroensFormat(double money)//Wants to receive value of type double
{
        NumberFormat dutchFormat = NumberFormat.getCurrencyInstance();
        money = money;
        String twoDecimals = dutchFormat.format(money); //Format to string
        if(tweeDecimalen.matches(".*[.]...[,]00$")){
            String zeroDecimals = twoDecimals.substring(0, twoDecimals.length() -3);
                return zeroDecimals;
        }
        if(twoDecimals.endsWith(",00")){
            String zeroDecimals = String.format("€ %.0f,-", money);
            return zeroDecimals; //Return with ,00 replaced to ,-
        }
        else{ //If endsWith != ,00 the actual twoDecimals string can be returned
            return twoDecimals;
        }
}

The method displayJeroensFormat that calls the method jeroensFormat()

    public void displayJeroensFormat()//@parameter double:
    {
        System.out.println(jeroensFormat(10.5)); //Example for two decimals
        System.out.println(jeroensFormat(10.95)); //Example for two decimals
        System.out.println(jeroensFormat(10.00)); //Example for zero decimals
        System.out.println(jeroensFormat(100.000)); //Example for zero decimals
    }

Will have the following output:

€ 10,50
€ 10,95
€ 10,-
€ 100.000 (In Holland numbers bigger than € 999,- and wit no decimals don't have ,-)

This code uses your current currency. In my case that's Holland so the formatted string for me will be different than for someone in the US.

• Holland: 999.999,99
• US: 999,999.99

Just watch the last 3 characters of those numbers. My code has an if statement to check if the last 3 characters are equal to ",00". To use this in the US you might have to change that to ".00" if it doesn't work already.

Upon investigation, it's also worth noting that when you want to start using docker in a new terminal window, the correct command is:

$(boot2docker shellinit)

I had tested these commands:

>>  docker info
Get http:///var/run/docker.sock/v1.15/info: dial unix /var/run/docker.sock: no such file or directory
>>  boot2docker shellinit
Writing /Users/ddavison/.boot2docker/certs/boot2docker-vm/ca.pem
Writing /Users/ddavison/.boot2docker/certs/boot2docker-vm/cert.pem

    export DOCKER_HOST=tcp://192.168.59.103:2376

    export DOCKER_TLS_VERIFY=1
>> docker info
Get http:///var/run/docker.sock/v1.15/info: dial unix /var/run/docker.sock: no such file or directory

Notice that docker info returned that same error. however.. when using $(boot2docker shellinit)...

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

Had the same problem. For me it worked to call

viewPage.setAdapter( adapter );

again which caused reinstantiating the pages again.

I think this is very easy to do with very few lines. here is my solution

.buttonToLink{
   background: none;
   border: none;
   color: red
}

.buttonToLink:hover{
   background: none;
   text-decoration: underline;
}

<button  class="buttonToLink">A simple link button</button>

Shortest Code

[x for _,x in sorted(zip(Y,X))]

Example:

X = ["a", "b", "c", "d", "e", "f", "g", "h", "i"]
Y = [ 0,   1,   1,    0,   1,   2,   2,   0,   1]

Z = [x for _,x in sorted(zip(Y,X))]
print(Z)  # ["a", "d", "h", "b", "c", "e", "i", "f", "g"]

Generally Speaking

[x for _, x in sorted(zip(Y,X), key=lambda pair: pair[0])]

Explained:

1. zip the two lists.
2. create a new, sorted list based on the zip using sorted().
3. using a list comprehension extract the first elements of each pair from the sorted, zipped list.

For more information on how to set\use the key parameter as well as the sorted function in general, take a look at this.

In Symfony you can use this for protocol and host:

{{ app.request.schemeAndHttpHost }}

Though @alessandro1997 gave a perfect answer about concatenation.

For your first array example use,

a = numpy.arange(5)

To initialize big_array, use

big_array = numpy.zeros((10,4))

This assumes you want to initialize with zeros, which is pretty typical, but there are many other ways to initialize an array in numpy.

Edit: If you don't know the size of big_array in advance, it's generally best to first build a Python list using append, and when you have everything collected in the list, convert this list to a numpy array using numpy.array(mylist). The reason for this is that lists are meant to grow very efficiently and quickly, whereas numpy.concatenate would be very inefficient since numpy arrays don't change size easily. But once everything is collected in a list, and you know the final array size, a numpy array can be efficiently constructed.

just get element using

   function name()
   {  
   document.getElementById('elementid').value = "";
   }

you can call this function on onfocus event of textbox and clear the value

Two years on, and this issue is still around...

In iOS 8 / XCode 6.1, I was sometimes finding that my UILabel (created in a UITableViewCell, with AutoLayout turned on, and flexible constraints so it had plenty of space) wouldn't resize itself to fit the text string.

The solution, as in previous years, was to set the text, and then call sizeToFit.

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    . . .
    cell.lblCreatedAt.text = [note getCreatedDateAsString];
    [cell.lblCreatedAt sizeToFit];
}

(Sigh.)

The se argument from the example also isn't in the help or online documentation.

When 'se' in geom_smooth is set 'FALSE', the error shading region is not visible

I have encountered this one too and this is my solution.

If you are encountering an invalid json object exception when parsing data, even though you know that your json string is correct, stringify the data you received in your ajax code before parsing it to JSON:

$.post(CONTEXT+"servlet/capture",{
        yesTransactionId : yesTransactionId, 
        productOfferId : productOfferId
        },
        function(data){
            try{
                var trimData = $.trim(JSON.stringify(data));
                var obj      = $.parseJSON(trimData);
                if(obj.success == 'true'){ 
                    //some codes ...

The use of @Qualifier will solve the issue.
Explained as below example : 
public interface PersonType {} // MasterInterface

@Component(value="1.2") 
public class Person implements  PersonType { //Bean implementing the interface
@Qualifier("1.2")
    public void setPerson(PersonType person) {
        this.person = person;
    }
}

@Component(value="1.5")
public class NewPerson implements  PersonType { 
@Qualifier("1.5")
    public void setNewPerson(PersonType newPerson) {
        this.newPerson = newPerson;
    }
}

Now get the application context object in any component class :

Object obj= BeanFactoryAnnotationUtils.qualifiedBeanOfType((ctx).getAutowireCapableBeanFactory(), PersonType.class, type);//type is the qualifier id

you can the object of class of which qualifier id is passed.

Arrays are not changeable after initialization. You have to give it a value, and that value is what that array length stays. You can create multiple arrays to contain certain parts of player information like their hand and such, and then create an arrayList to sort of shepherd those arrays.

Another point of contention I see, and I may be wrong about this, is the fact that your private Player[] InitializePlayers() is static where the class is now non-static. So:

private Player[] InitializePlayers(int playerCount)
{
 ...
}

My last point would be that you should probably have playerCount declared outside of the method that is going to change it so that the value that is set to it becomes the new value as well and it is not just tossed away at the end of the method's "scope."

Hope this helps

I just put into constructor something by reference, so the subform can change its value and main form can get new or modified object from subform.

You should add the target="_blank" and rel="noopener noreferrer" in the anchor tag.

For example:

<a target="_blank" rel="noopener noreferrer" href="http://your_url_here.html">Link</a>

Adding rel="noopener noreferrer" is not mandatory, but it's a recommended security measure. More information can be found in the links below.

Source:

• MDN | HTML element <a> | attribute target
• About rel=noopener
• Opens External Anchors Using rel="noopener"

While viewing the html email try inspecting the element on that link and see what is overwriting it. Use that class and define it that style again in your head style and define the text-decoration: none !important;

In my case these are the classes that are overwriting my inline style so declared this on the head of my html email and defined the style that I want implemented.

It worked for me, hope it will work on your one too.

.ii a[href]{
text-decoration: none !important;
}

#yiv8915438996 a:link, #yiv8915438996 span.yiv8915438996MsoHyperlink{
text-decoration: none !important;
}   

#yiv8915438996 a:visited, #yiv8915438996 span.yiv8915438996MsoHyperlinkFollowed{
text-decoration: none !important;
}   

I really struggled with getting the results of jQuery ajax into my variables at the "document.ready" stage of events.

jQuery's ajax would load into my variables when a user triggered an "onchange" event of a select box after the page had already loaded, but the data would not feed the variables when the page first loaded.

I tried many, many, many different methods, but in the end, it was Charles Guilbert's method that worked best for me.

Hats off to Charles Guilbert! Using his answer, I am able to get data into my variables, even when my page first loads.

Here's an example of the working script:

    jQuery.extend
    (
        {
            getValues: function(url) 
            {
                var result = null;
                $.ajax(
                    {
                        url: url,
                        type: 'get',
                        dataType: 'html',
                        async: false,
                        cache: false,
                        success: function(data) 
                        {
                            result = data;
                        }
                    }
                );
               return result;
            }
        }
    );

    // Option List 1, when "Cats" is selected elsewhere
    optList1_Cats += $.getValues("/MyData.aspx?iListNum=1&sVal=cats");

    // Option List 1, when "Dogs" is selected elsewhere
    optList1_Dogs += $.getValues("/MyData.aspx?iListNum=1&sVal=dogs");

    // Option List 2, when "Cats" is selected elsewhere
    optList2_Cats += $.getValues("/MyData.aspx?iListNum=2&sVal=cats");

    // Option List 2, when "Dogs" is selected elsewhere
    optList2_Dogs += $.getValues("/MyData.aspx?iListNum=2&sVal=dogs");

This query works correct with composite keys also:

select c.constraint_name
    , x.table_schema as schema_name
    , x.table_name
    , x.column_name
    , y.table_schema as foreign_schema_name
    , y.table_name as foreign_table_name
    , y.column_name as foreign_column_name
from information_schema.referential_constraints c
join information_schema.key_column_usage x
    on x.constraint_name = c.constraint_name
join information_schema.key_column_usage y
    on y.ordinal_position = x.position_in_unique_constraint
    and y.constraint_name = c.unique_constraint_name
order by c.constraint_name, x.ordinal_position

Sometimes, this error pops up because of the kernel has reached its limit. Try to restart the kernel redo the necessary steps.

mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given

This means that the first parameter you passed is a boolean (true or false).

The first parameter is $result, and it is false because there is a syntax error in the query.

" ... WHERE PartNumber = $partid';"

You should never directly include a request variable in a SQL query, else the users are able to inject SQL in your queries. (See SQL injection.)

You should escape the variable:

" ... WHERE PartNumber = '" . mysqli_escape_string($conn,$partid) . "';"

Or better, use Prepared Statements.

SELECT
  campo1,
  campo2,
  campo3,
  campo4
FROM tabela1
WHERE CONCAT(campo1,campo2,campo3,IF(campo4 IS NULL,'',campo4))
NOT IN
(SELECT CONCAT(campo1,campo2,campo3,IF(campo4 IS NULL,'',campo4))
FROM tabela2);

Hope this will help you. Assumed that login form has: username and password inputs.

if(isset($_POST['username']) && trim($_POST['username']) != "" && isset($_POST['password']) && trim($_POST['password']) != ""){
//login
} else {
//register
}

Here's the important part from the man page:

As the list of files/directories to transfer is built, rsync checks each name to be transferred against the list of include/exclude patterns in turn, and the first matching pattern is acted on: if it is an exclude pattern, then that file is skipped; if it is an include pattern then that filename is not skipped; if no matching pattern is found, then the filename is not skipped.

To summarize:

• Not matching any pattern means a file will be copied!
• The algorithm quits once any pattern matches

Also, something ending with a slash is matching directories (like find -type d would).

Let's pull apart this answer from above.

rsync -zarv  --prune-empty-dirs --include "*/"  --include="*.sh" --exclude="*" "$from" "$to"

1. Don't skip any directories
2. Don't skip any .sh files
3. Skip everything
4. (Implicitly, don't skip anything, but the rule above prevents the default rule from ever happening.)

Finally, the --prune-empty-directories keeps the first rule from making empty directories all over the place.

Once you have parsed the timestamp string and have a time object (see other answers for details), you can use Time.to_formatted_s from Rails. It has several formats built in that you can specify with symbols.

Quote:

time = Time.now                     # => Thu Jan 18 06:10:17 CST 2007

time.to_formatted_s(:time)          # => "06:10"
time.to_s(:time)                    # => "06:10"

time.to_formatted_s(:db)            # => "2007-01-18 06:10:17"
time.to_formatted_s(:number)        # => "20070118061017"
time.to_formatted_s(:short)         # => "18 Jan 06:10"
time.to_formatted_s(:long)          # => "January 18, 2007 06:10"
time.to_formatted_s(:long_ordinal)  # => "January 18th, 2007 06:10"
time.to_formatted_s(:rfc822)        # => "Thu, 18 Jan 2007 06:10:17 -0600"

(Time.to_s is an alias)

You can also define your own formats - usually in an initializer (Thanks to Dave Newton for pointing this out). This is how it's done:

# config/initializers/time_formats.rb
Time::DATE_FORMATS[:month_and_year] = "%B %Y"
Time::DATE_FORMATS[:short_ordinal] = lambda { |time| time.strftime("%B #{time.day.ordinalize}") }

With me, this problem in base Address in app.config of WCF service: When I've used:

<baseAddresses><add baseAddress="http://127.0.0.1:9022/Service/GatewayService"/> </baseAddresses>

it's ok if use .net to connect with public ip or domain.

But when use PHP's SoapClient to connect to "http://[online ip]:9022/Service/GatewayService", it's throw exception "Coulod not connect to host"

I've changed baseAddress to [online ip]:9022 and everything's ok.

Monkey is right, according to the link given by monkey

Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location.

I am not sure if it is angular's fault that no map files were generated. But you can turn off source map files by unchecking this option in chrome console setting

If we need to find an element from the list, then we can use the Find and FindAll extensions method, but there is a slight difference between them. Here is an example.

 List<int> items = new List<int>() { 10, 9, 8, 4, 8, 7, 8 };

  // It will return only one 8 as Find returns only the first occurrence of matched elements.
     var result = items.Find(ls => ls == 8);      
 // this will returns three {8,8,8} as FindAll returns all the matched elements.
      var result1 = items.FindAll(ls => ls == 8); 

I wrote a shell script called fullpath that contains this code, use it everyday:

    #!/bin/sh
    for i in $* ; do
        echo $(pwd)/$i
    done

Put it somewhere in your PATH, and make it executable(chmod 755 fullpath) then just use
fullpath file_or_directory

Check this thread out: read and write image file.

Also, have a look at this other question at Stackoverflow.

I've been wrestling with this, and I know there are other options, but I've come to the conclusion the safest pattern is:

create table destination_old as select * from destination;

drop table destination;

create table destination as select
d.*, s.country
from destination_old d left join source s
on d.id=s.id;

It's safe because you have a copy of destination before you altered it. I suspect that update statements with joins weren't included in SQLite because they're powerful but a bit risky.

Using the pattern above you end up with two country fields. You can avoid that by explicitly stating all of the columns you want to retrieve from destination_old and perhaps using coalesce to retrieve the values from destination_old if the country field in source is null. So for example:

create table destination as select
d.field1, d.field2,...,coalesce(s.country,d.country) country
from destination_old d left join source s
on d.id=s.id;

Use pathlib.

Python 3.5 and above:

from pathlib import Path
contents = Path(file_path).read_text()

For lower versions of Python use pathlib2:

$ pip install pathlib2

Then

from pathlib2 import Path
contents = Path(file_path).read_text()

Writing is just as easy:

Path(file_path).write_text('my text')

As Alex Filipovici mentioned the issue was a wrong encoding. The file I read in was UTF-8-BOM and threw the above error on Convert.FromBase64String(). Changing to UTF-8 did work without problems.

require will throw a PHP Fatal Error if the file cannot be loaded. (Execution stops)

include produces a Warning if the file cannot be loaded. (Execution continues)

Here is a nice illustration of include and require difference:

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

No, there is no such printf width specifier to print floating-point with maximum precision. Let me explain why.

The maximum precision of float and double is variable, and dependent on the actual value of the float or double.

Recall float and double are stored in sign.exponent.mantissa format. This means that there are many more bits used for the fractional component for small numbers than for big numbers.

For example, float can easily distinguish between 0.0 and 0.1.

float r = 0;
printf( "%.6f\n", r ) ; // 0.000000
r+=0.1 ;
printf( "%.6f\n", r ) ; // 0.100000

But float has no idea of the difference between 1e27 and 1e27 + 0.1.

r = 1e27;
printf( "%.6f\n", r ) ; // 999999988484154753734934528.000000
r+=0.1 ;
printf( "%.6f\n", r ) ; // still 999999988484154753734934528.000000

This is because all the precision (which is limited by the number of mantissa bits) is used up for the large part of the number, left of the decimal.

The %.f modifier just says how many decimal values you want to print from the float number as far as formatting goes. The fact that the accuracy available depends on the size of the number is up to you as the programmer to handle. printf can't/doesn't handle that for you.

$*

Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands to a single word with the value of each parameter separated by the first character of the IFS special variable. That is, "$*" is equivalent to "$1c$2c...", where c is the first character of the value of the IFS variable. If IFS is unset, the parameters are separated by spaces. If IFS is null, the parameters are joined without intervening separators.

$@

Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" ... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).

Arrays.asList() method simply returns List type

char [] arr = { 'c','a','t'};    
ArrayList<Character> chars = new ArrayList<Character>();

To add the array into the list, first convert it to list and then call addAll

List arrList = Arrays.asList(arr);
chars.addAll(arrList);

The following line will cause compiler error

chars.addAll(Arrays.asList(arr));

I had the same problem and reset didn't fix it. Then the resharper support helped me. Solution was very simple! I'm from Russia and usually my default keyboard is Russian. In control panel | language settings | change keyboard - I changed default keyboard to English. Then reapply settings in VS: Resharper|Options|Keyboard&Menus - apply R# scheme. And the problem was fixed :)

The Pixastic library does exactly what you want. However, it will only work on browsers that have canvas support. For those older browsers, you'll either need to:

1. supply a server-side fallback, or
2. tell the user that you're very sorry, but he'll need to get a more modern browser.

Of course, option #2 isn't very user-friendly. However, if your intent is to provide a pure client-only tool and/or you can't support a fallback back-end cropper (e.g. maybe you're writing a browser extension or offline Chrome app, or maybe you can't afford a decent hosting provider that provides image manipulation libraries), then it's probably fair to limit your user base to modern browsers.

EDIT: If you don't want to learn Pixastic, I have added a very simple cropper on jsFiddle here. It should be possible to modify and integrate and use the drawCroppedImage function with Jcrop.

The easiest method is to go to your .xml file in text mode, and replace the top line:

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

And then proceed to replace it with:

<android.widget.RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

If you then go back into design mode, you can see that you now have a relative layout. This also automatically changes the end tag, so no issues there.

If possible, as non-member and non-friend functions.

As described by Herb Sutter and Scott Meyers, prefer non-friend non-member functions to member functions, to help increase encapsulation.

In some cases, like C++ streams, you won't have the choice and must use non-member functions.

But still, it does not mean you have to make these functions friends of your classes: These functions can still acess your class through your class accessors. If you succeed in writting those functions this way, then you won.

About operator << and >> prototypes

I believe the examples you gave in your question are wrong. For example;

ostream & operator<<(ostream &os) {
    return os << paragraph;
}

I can't even start to think how this method could work in a stream.

Here are the two ways to implement the << and >> operators.

Let's say you want to use a stream-like object of type T.

And that you want to extract/insert from/into T the relevant data of your object of type Paragraph.

Generic operator << and >> function prototypes

The first being as functions:

// T << Paragraph
T & operator << (T & p_oOutputStream, const Paragraph & p_oParagraph)
{
   // do the insertion of p_oParagraph
   return p_oOutputStream ;
}

// T >> Paragraph
T & operator >> (T & p_oInputStream, const Paragraph & p_oParagraph)
{
   // do the extraction of p_oParagraph
   return p_oInputStream ;
}

Generic operator << and >> method prototypes

The second being as methods:

// T << Paragraph
T & T::operator << (const Paragraph & p_oParagraph)
{
   // do the insertion of p_oParagraph
   return *this ;
}

// T >> Paragraph
T & T::operator >> (const Paragraph & p_oParagraph)
{
   // do the extraction of p_oParagraph
   return *this ;
}

Note that to use this notation, you must extend T's class declaration. For STL objects, this is not possible (you are not supposed to modify them...).

And what if T is a C++ stream?

Here are the prototypes of the same << and >> operators for C++ streams.

For generic basic_istream and basic_ostream

Note that is case of streams, as you can't modify the C++ stream, you must implement the functions. Which means something like:

// OUTPUT << Paragraph
template <typename charT, typename traits>
std::basic_ostream<charT,traits> & operator << (std::basic_ostream<charT,traits> & p_oOutputStream, const Paragraph & p_oParagraph)
{
   // do the insertion of p_oParagraph
   return p_oOutputStream ;
}

// INPUT >> Paragraph
template <typename charT, typename traits>
std::basic_istream<charT,traits> & operator >> (std::basic_istream<charT,traits> & p_oInputStream, const CMyObject & p_oParagraph)
{
   // do the extract of p_oParagraph
   return p_oInputStream ;
}

For char istream and ostream

The following code will work only for char-based streams.

// OUTPUT << A
std::ostream & operator << (std::ostream & p_oOutputStream, const Paragraph & p_oParagraph)
{
   // do the insertion of p_oParagraph
   return p_oOutputStream ;
}

// INPUT >> A
std::istream & operator >> (std::istream & p_oInputStream, const Paragraph & p_oParagraph)
{
   // do the extract of p_oParagraph
   return p_oInputStream ;
}

Rhys Ulerich commented about the fact the char-based code is but a "specialization" of the generic code above it. Of course, Rhys is right: I don't recommend the use of the char-based example. It is only given here because it's simpler to read. As it is only viable if you only work with char-based streams, you should avoid it on platforms where wchar_t code is common (i.e. on Windows).

Hope this will help.

Use next:

(1..10).each do |a|
  next if a.even?
  puts a
end

prints:

1
3   
5
7
9

For additional coolness check out also redo and retry.

Works also for friends like times, upto, downto, each_with_index, select, map and other iterators (and more generally blocks).

For more info see http://ruby-doc.org/docs/ProgrammingRuby/html/tut_expressions.html#UL.

One additional point to note here is that, as the basic principle of Spark RDD is immutability. The repartition or coalesce will create new RDD. The base RDD will continue to have existence with its original number of partitions. In case the use case demands to persist RDD in cache, then the same has to be done for the newly created RDD.

scala> pairMrkt.repartition(10)
res16: org.apache.spark.rdd.RDD[(String, Array[String])] =MapPartitionsRDD[11] at repartition at <console>:26

scala> res16.partitions.length
res17: Int = 10

scala>  pairMrkt.partitions.length
res20: Int = 2

You can use the foreach for an simple array like

int[] test = { 0, 1, 2, 3, ...};

And you can use the for when you have a 2D array

int[][] test = {{1,2,3,4},
                {5,2,6,5,8}};

You can sort an array ([...]) with the .sort function:

var people = [
    {'name': 'a75', 'item1': false, 'item2': false},
    {'name': 'z32', 'item1': true,  'item2': false},
    {'name': 'e77', 'item1': false, 'item2': false},
];

var sorted = people.sort(function IHaveAName(a, b) { // non-anonymous as you ordered...
    return b.name < a.name ?  1 // if b should come earlier, push a to end
         : b.name > a.name ? -1 // if b should come later, push a to begin
         : 0;                   // a and b are equal
});

If you do not use a tool to merge, first copy your code outside:

- `checkout master`
- `git pull` / get new commit
- `git checkout` to your branch
- `git rebase master`

It resolve conflict and you can copy your code.

You can use a bitset

bitset<8> b(string("00010000"));
int i = (int)(bs.to_ulong());
cout<<i;

Just add these lines

     override fun onBackPressed() {
            if(navController.popBackStack().not()) {
            //Last fragment: Do your operation here 
            finish()
   } 

navController.popBackStack() will just pop your fragment if this is not your last fragment

I came across the same problem using a Wordpress page and plugin. This didn't work for the iframe plugin

[iframe src="https://itunes.apple.com/gb/app/witch-hunt/id896152730#?platform=iphone"]

but this does:

[iframe src="https://itunes.apple.com/gb/app/witch-hunt/id896152730"  width="100%" height="480" ]

As you see, I just left off the #?platform=iphone part in the end.

When a CSS property shows as struck-through, it means that the crossed-out style was applied, but then overridden by a more specific selector, a more local rule, or by a later property within the same rule.

(Special cases: a style will also be shown as struck-through if a style exists in an matching rule but is commented out, or if you've manually disabled it by unchecking it within the Chrome developer tools. It will also show as crossed out, but with an error icon, if the style has a syntax error.)

For example, if a background color was applied to all divs, but a different background color was applied to divs with a certain id, the first color will show up but will be crossed out, as the second color has replaced it (in the property list for the div with that id).

Use this construction, to keep all input params but page

{!! $myItems->appends(Request::capture()->except('page'))->render() !!}

Why?

1) you strip down everything that added to request like that

  $request->request->add(['variable' => 123]);

2) you don't need $request as input parameter for the function

3) you are excluding "page"

PS) and it works for Laravel 5.1

If you save the state of the application in a bundle (typically non-persistent, dynamic data in onSaveInstanceState), it can be passed back to onCreate if the activity needs to be recreated (e.g., orientation change) so that you don't lose this prior information. If no data was supplied, savedInstanceState is null.

... you should use the onPause() method to write any persistent data (such as user edits) to storage. In addition, the method onSaveInstanceState(Bundle) is called before placing the activity in such a background state, allowing you to save away any dynamic instance state in your activity into the given Bundle, to be later received in onCreate(Bundle) if the activity needs to be re-created. See the Process Lifecycle section for more information on how the lifecycle of a process is tied to the activities it is hosting. Note that it is important to save persistent data in onPause() instead of onSaveInstanceState(Bundle) because the latter is not part of the lifecycle callbacks, so will not be called in every situation as described in its documentation.

There are a few things you can try to get this working.

1. Be ABSOLUTELY sure your script is being pulled into the page, one way to check is by using the 'sources' tab in the Chrome Debugger and searching for the file.

2. Be sure that you've included the script after you've included jQuery, as it is most certainly dependant upon that.

Other than that, I checked out the API and you're definitely doing everything right as far as I can see. Best of luck friend!

EDIT: Ensure you close your script tag. There's an answer below that points to that being the solution.

DataSet ds = new DataSet();

using (OleDbConnection connection = new OleDbConnection(connectionString))
using (OleDbCommand command = new OleDbCommand(query, connection))
using (OleDbDataAdapter adapter = new OleDbDataAdapter(command))
{
    adapter.Fill(ds);
}

return ds;

Great solution but for my Windows I need make a modifications. Below the modify code

function Zip($source, $destination){

if (!extension_loaded('zip') || !file_exists($source)) {
    return false;
}

$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
    return false;
}

$source = str_replace('\\', '/', realpath($source));

if (is_dir($source) === true)
{
    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

    foreach ($files as $file)
    {
        $file = str_replace('\\', '/', $file);

        // Ignore "." and ".." folders
        if( in_array(substr($file, strrpos($file, '/')+1), array('.', '..')) )
            continue;

        if (is_dir($file) === true)
        {
            $zip->addEmptyDir(str_replace($source . '/', '', $file));
        }
        else if (is_file($file) === true)
        {

            $str1 = str_replace($source . '/', '', '/'.$file);
            $zip->addFromString($str1, file_get_contents($file));

        }
    }
}
else if (is_file($source) === true)
{
    $zip->addFromString(basename($source), file_get_contents($source));
}

return $zip->close();
}

Try

<button [ngClass]="type === 'mybutton' ? namespace + '-mybutton' : ''"></button>

instead.

or

<button [ngClass]="[type === 'mybutton' ? namespace + '-mybutton' : '']"></button>

or even

<button class="{{type === 'mybutton' ? namespace + '-mybutton' : ''}}"></button>

will work but extra benefit of using ngClass is that it does not overwrite other classes that are added by any other method( eg: [class.xyz] directive or class attribute, etc.) as class does.

Angular 9 Update

The new compiler, Ivy, brings more clarity and predictability to what happens when there are different types of class-bindings on the same element. Read More about it here.

ngClass takes three types of input

• Object: each key corresponds to a CSS class name, you can't have dynamic keys, because key 'key' "key" are all same, and [key] is not supported AFAIK.
• Array: can only contain list of classes, no conditions, although ternary operator works
• String/ expression: just like normal class attribute

I was having the same issue

Role.java

 @ManyToMany(mappedBy = "roles", fetch = FetchType.LAZY,cascade = CascadeType.ALL)
 Set<BusinessUnitMaster> businessUnits =new HashSet<>();

BusinessUnitMaster.java

@ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@JoinTable(
        name = "BusinessUnitRoles",
        joinColumns = {@JoinColumn(name = "unit_id", referencedColumnName = "record_id")},
        inverseJoinColumns = {@JoinColumn(name = "role_id", referencedColumnName = "record_id")}
)
private Set<Role> roles=new HashSet<>();

the problem is that when you create BusinessUnitMaster and Role you have to save the object for both sides for RoleService.java

roleRepository.save(role);

for BusinessUnitMasterService.java

businessUnitMasterRepository.save(businessUnitMaster);

org.apache.commons.lang3.ArrayUtils#add(T[], int, T) is deprecated in newest commons lang3, you can use org.apache.commons.lang3.ArrayUtils#insert(int, T[], T...) instead.

Deprecated this method has been superseded by insert(int, T[], T...) and may be removed in a future release. Please note the handling of null input arrays differs in the new method: inserting X into a null array results in null not X

Sample code:

    Assert.assertArrayEquals
            (org.apache.commons.lang3.ArrayUtils.insert
            (4, new int[]{1, 2, 3, 4, 5, 6}, 87), new int[]{1, 2, 3, 4, 87, 5, 6});

At the risk of being years late and off topic - and notwithstanding @Marc's excellent insight, in Swift it looks like:

let basename = NSURL(string: "path/to/file.ext")?.URLByDeletingPathExtension?.lastPathComponent

import React, { Component } from "react";
import axios from "axios";

const CancelToken = axios.CancelToken;

let cancel;

class Abc extends Component {
  componentDidMount() {
    this.Api();
  }

  Api() {
      // Cancel previous request
    if (cancel !== undefined) {
      cancel();
    }
    axios.post(URL, reqBody, {
        cancelToken: new CancelToken(function executor(c) {
          cancel = c;
        }),
      })
      .then((response) => {
        //responce Body
      })
      .catch((error) => {
        if (axios.isCancel(error)) {
          console.log("post Request canceled");
        }
      });
  }

  render() {
    return <h2>cancel Axios Request</h2>;
  }
}

export default Abc;

I reopen eclipse, edit one of my xml files and then discover that my activy class was refering android.R instead of my package "R" :-)

Another option that is perhaps the simplest one in terms of the command line is adding the built-in --trace-time option:

curl -X POST -d @file server:port --trace-time

Even though it technically does not output the timings of the various steps as requested by the OP, it does display the timestamps for all steps of the request as shown below. Using this, you can (fairly easily) calculate how long each step has taken.

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

Date.strptime(updated,"%a, %d %m %Y %H:%M:%S %Z")

Should be:

Date.strptime(updated, '%a, %d %b %Y %H:%M:%S %Z')

There is also this free API that you can use to make free barcodes in java.

Java 8 provides different utility api methods to help us sort the streams better.

If your list is a list of Integers(or Double, Long, String etc.,) then you can simply sort the list with default comparators provided by java.

List<Integer> integerList = Arrays.asList(1, 4, 3, 4, 5);

Creating comparator on fly:

integerList.stream().sorted((i1, i2) -> i1.compareTo(i2)).forEach(System.out::println);

With default comparator provided by java 8 when no argument passed to sorted():

integerList.stream().sorted().forEach(System.out::println); //Natural order

If you want to sort the same list in reverse order:

 integerList.stream().sorted(Comparator.reverseOrder()).forEach(System.out::println); // Reverse Order

If your list is a list of user defined objects, then:

List<Person> personList = Arrays.asList(new Person(1000, "First", 25, 30000),
        new Person(2000, "Second", 30, 45000),
        new Person(3000, "Third", 35, 25000));

Creating comparator on fly:

personList.stream().sorted((p1, p2) -> ((Long)p1.getPersonId()).compareTo(p2.getPersonId()))
        .forEach(person -> System.out.println(person.getName()));

Using Comparator.comparingLong() method(We have comparingDouble(), comparingInt() methods too):

personList.stream().sorted(Comparator.comparingLong(Person::getPersonId)).forEach(person -> System.out.println(person.getName()));

Using Comparator.comparing() method(Generic method which compares based on the getter method provided):

personList.stream().sorted(Comparator.comparing(Person::getPersonId)).forEach(person -> System.out.println(person.getName()));

We can do chaining too using thenComparing() method:

personList.stream().sorted(Comparator.comparing(Person::getPersonId).thenComparing(Person::getAge)).forEach(person -> System.out.println(person.getName())); //Sorting by person id and then by age.

Person class

public class Person {
    private long personId;
    private String name;
    private int age;
    private double salary;

    public long getPersonId() {
        return personId;
    }

    public void setPersonId(long personId) {
        this.personId = personId;
    }

    public Person(long personId, String name, int age, double salary) {
        this.personId = personId;
        this.name = name;
        this.age = age;

        this.salary = salary;
    }

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }
}

You can use this code:

// Create an array that matches any country to its id (as String):
String[][] countriesId = new String[NUMBER_OF_COUNTRIES_SUPPORTED][];

// Initialize the array, where the first column will be the country's name (in uppercase) and the second column will be its id (as String):
countriesId[0] = new String[] {"US", String.valueOf(R.drawable.us)};
countriesId[1] = new String[] {"FR", String.valueOf(R.drawable.fr)};
// and so on...

// And after you get the variable "countryCode":
int i;
for(i = 0; i<countriesId.length; i++) {
   if(countriesId[i][0].equals(countryCode))
      break;
}
// Now "i" is the index of the country

img.setImageResource(Integer.parseInt(countriesId[i][1]));

For those who dont want to use datepicker method

var alldatepicker=  $("[class$=hasDatepicker]");

alldatepicker.each(function(){

var value=$(this).val();

var today = new Date();

var dd = today.getDate();

var mm = today.getMonth()+1; //January is 0!

var yyyy = today.getFullYear();

if(dd<10) {

    dd='0'+dd

} 
if(mm<10) {

    mm='0'+mm

} 
today = mm+'/'+dd+'/'+yyyy;
if(value!=''){
if(value>today){
alert("Date cannot be greater than current date");
}
}
}); 

I just put this into a static class.

  const int WM_USER = 0x400;
  const int PBM_SETSTATE = WM_USER + 16;
  const int PBM_GETSTATE = WM_USER + 17;

  [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
  static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

  public enum ProgressBarStateEnum : int
  {
   Normal = 1,
   Error = 2,
   Paused = 3,
  }

  public static ProgressBarStateEnum GetState(this ProgressBar pBar)
  {
   return (ProgressBarStateEnum)(int)SendMessage(pBar.Handle, PBM_GETSTATE, IntPtr.Zero, IntPtr.Zero);
  }

  public static void SetState(this ProgressBar pBar, ProgressBarStateEnum state)
  {
   SendMessage(pBar.Handle, PBM_SETSTATE, (IntPtr)state, IntPtr.Zero);
  } 

Hope it helps,

Marc

Adding to what @Shog9 posted, you can also restrict dates individually in the beforeShowDay: callback function.

You supply a function that takes a date and returns a boolean array:

"$(".selector").datepicker({ beforeShowDay: nationalDays}) 
natDays = [[1, 26, 'au'], [2, 6, 'nz'], [3, 17, 'ie'], [4, 27, 'za'], 
[5, 25, 'ar'], [6, 6, 'se'], [7, 4, 'us'], [8, 17, 'id'], [9, 7, 
'br'], [10, 1, 'cn'], [11, 22, 'lb'], [12, 12, 'ke']]; 
function nationalDays(date) { 
    for (i = 0; i < natDays.length; i++) { 
      if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == 
natDays[i][1]) { 
        return [false, natDays[i][2] + '_day']; 
      } 
    } 
  return [true, '']; 
} 

A character in Java is a Unicode code-unit which is treated as an unsigned number. So if you perform c = (char)b the value you get is 2^16 - 56 or 65536 - 56.

Or more precisely, the byte is first converted to a signed integer with the value 0xFFFFFFC8 using sign extension in a widening conversion. This in turn is then narrowed down to 0xFFC8 when casting to a char, which translates to the positive number 65480.

From the language specification:

5.1.4. Widening and Narrowing Primitive Conversion

First, the byte is converted to an int via widening primitive conversion (§5.1.2), and then the resulting int is converted to a char by narrowing primitive conversion (§5.1.3).

To get the right point use char c = (char) (b & 0xFF) which first converts the byte value of b to the positive integer 200 by using a mask, zeroing the top 24 bits after conversion: 0xFFFFFFC8 becomes 0x000000C8 or the positive number 200 in decimals.

Above is a direct explanation of what happens during conversion between the byte, int and char primitive types.

If you want to encode/decode characters from bytes, use Charset, CharsetEncoder, CharsetDecoder or one of the convenience methods such as new String(byte[] bytes, Charset charset) or String#toBytes(Charset charset). You can get the character set (such as UTF-8 or Windows-1252) from StandardCharsets.

The drawPolygon function below can be used to draw any polygon with rounded corners.

See it running here.

function drawPolygon(ctx, pts, radius) {
  if (radius > 0) {
    pts = getRoundedPoints(pts, radius);
  }
  var i, pt, len = pts.length;
  ctx.beginPath();
  for (i = 0; i < len; i++) {
    pt = pts[i];
    if (i == 0) {          
      ctx.moveTo(pt[0], pt[1]);
    } else {
      ctx.lineTo(pt[0], pt[1]);
    }
    if (radius > 0) {
      ctx.quadraticCurveTo(pt[2], pt[3], pt[4], pt[5]);
    }
  }
  ctx.closePath();
}

function getRoundedPoints(pts, radius) {
  var i1, i2, i3, p1, p2, p3, prevPt, nextPt,
      len = pts.length,
      res = new Array(len);
  for (i2 = 0; i2 < len; i2++) {
    i1 = i2-1;
    i3 = i2+1;
    if (i1 < 0) {
      i1 = len - 1;
    }
    if (i3 == len) {
      i3 = 0;
    }
    p1 = pts[i1];
    p2 = pts[i2];
    p3 = pts[i3];
    prevPt = getRoundedPoint(p1[0], p1[1], p2[0], p2[1], radius, false);
    nextPt = getRoundedPoint(p2[0], p2[1], p3[0], p3[1], radius, true);
    res[i2] = [prevPt[0], prevPt[1], p2[0], p2[1], nextPt[0], nextPt[1]];
  }
  return res;
};

function getRoundedPoint(x1, y1, x2, y2, radius, first) {
  var total = Math.sqrt(Math.pow(x2 - x1, 2) + Math.pow(y2 - y1, 2)),
      idx = first ? radius / total : (total - radius) / total;
  return [x1 + (idx * (x2 - x1)), y1 + (idx * (y2 - y1))];
};

The function receives an array with the polygon points, like this:

var canvas = document.getElementById("cv");
var ctx = canvas.getContext("2d");
ctx.strokeStyle = "#000000";
ctx.lineWidth = 5;

drawPolygon(ctx, [[20,   20],
                  [120,  20],
                  [120, 120],
                  [ 20, 120]], 10);
ctx.stroke();

This is a port and a more generic version of a solution posted here.

This is what I added in the CMakeList.txt (which worked):

# https://cmake.org/cmake/help/latest/command/find_package.html

Eclipse: failed to create the java virtual machine – message box

1. Open folder with Eclipse.exe and find eclipse.ini file
   

2. Replace -vmargs by your current real path of javaw.exe with

   -vm "c:\Program Files\Java\jdk1.7.0_07\bin\javaw.exe"
   

   or in case you've installed jre only:

   -vm "C:\Program Files\Java\jre7\bin\javaw.exe"
   

To see the window height while (or after) it is resized, try it:

$(window).resize(function() {
$('body').prepend('<div>' + $(window).height() - 46 + '</div>');
});

There are quite a few ways to get the result you are after. Lets break them in categories:

ES6 Values only:

Main method for this is Object.values. But using Object.keys and Array.map you could as well get to the expected result:

Object.values(obj)
Object.keys(obj).map(k => obj[k])

var obj = {_x000D_
  A: {_x000D_

console.log('Object.keys:', Object.keys(obj).map(k => obj[k]))

ES6 Key & Value:

Using map and ES6 dynamic/computed properties and destructuring you can retain the key and return an object from the map.

Object.keys(obj).map(k => ({[k]: obj[k]}))
Object.entries(obj).map(([k,v]) => ({[k]:v}))

var obj = {_x000D_
  A: {_x000D_
    name: "John"_x000D_
  },_x000D_
  B: {_x000D_
    name: "Ivan"_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log('Object.keys:', Object.keys(obj).map(k => ({_x000D_
  [k]: obj[k]_x000D_
})))_x000D_
console.log('Object.entries:', Object.entries(obj).map(([k, v]) => ({_x000D_
  [k]: v_x000D_
})))

Lodash Values only:

The method designed for this is _.values however there are "shortcuts" like _.map and the utility method _.toArray which would also return an array containing only the values from the object. You could also _.map though the _.keys and get the values from the object by using the obj[key] notation.

Note: _.map when passed an object would use its baseMap handler which is basically forEach on the object properties.

_.values(obj)
_.map(obj)
_.toArray(obj)
_.map(_.keys(obj), k => obj[k])

var obj = {_x000D_
  A: {_x000D_
    name: "John"_x000D_
  },_x000D_
  B: {_x000D_

Note that in the above examples ES6 is used (arrow functions and dynamic properties). You can use lodash _.fromPairs and other methods to compose an object if ES6 is an issue.

You can use the replace function

UPDATE your_table SET field = REPLACE(your_field, 'cat','dog')

The function definition is as follows (got from here):

replace(string text, from text, to text)

and returns the modified text. You can also check out this sql fiddle.

I create equations with random numbers in VBA and for x squared put in x^2.

I read each square (or textbox) text into a string.

I then read each character in the string in turn and note the location of the ^ ("hats")'s in each.

Say the hats were at positions 4, 8 and 12.

I then "chop out" the first hat - the position of the character to be superscripted is now 4, the position of the other hats is now 7 and 11. I chop out the second hat, the character to superscript is now at 7 and the hat has moved to 10. I chop out the last hat .. the superscript character is now position 10.

I now select each character in turn and change the font to superscript.

Thus I can fill a whole spreadsheet with algebra using ^ and then call a routine to tidy it up.

For big powers like x to the 23 I build x^2^3 and the above routine does it.

$last = array_slice($array, -1, 1, true);

See http://php.net/array_slice for details on what the arguments mean.

P.S. Unlike the other answers, this one actually does what you want. :-)

Use replace method of string like the following way:

String x="\"abcd";
String z=x.replace("\"", "");
System.out.println(z);

Output:

abcd

A .java file is the code file. A .class file is the compiled file.

It's not exactly "conversion" - it's compilation. Suppose your file was called "herb.java", you would write (in the command prompt):

 javac herb.java

It will create a herb.class file in the current folder.

It is "executable" only if it contains a static void main(String[]) method inside it. If it does, you can execute it by running (again, command prompt:)

 java herb

Here comes a rather obsqure idea. When every year dividable with 100 gets 365 days, what shall be done at this time? In the far future, when even years dividable with 400 only can get 365 days.

Then there is a possibility or reason to make corrections in years dividable with 80. Normal years will have 365 day and those dividable with 400 can get 366 days. Or is this a loose-loose situation.

The following should do what you want:

x <- data.frame(X1=sample(c(1:3,NaN), 200, replace=TRUE), X2=sample(c(4:6,NaN), 200, replace=TRUE))
head(x)
x <- replace(x, is.na(x), 0)
head(x)

In case the code gets lost again, here are the two main functions:

function doGetCaretPosition(ctrl)
{
 var CaretPos = 0;

 if (ctrl.selectionStart || ctrl.selectionStart == 0)
 {// Standard.
  CaretPos = ctrl.selectionStart;
 }
 else if (document.selection)
 {// Legacy IE
  ctrl.focus ();
  var Sel = document.selection.createRange ();
  Sel.moveStart ('character', -ctrl.value.length);
  CaretPos = Sel.text.length;
 }

 return (CaretPos);
}


function setCaretPosition(ctrl,pos)
{
 if (ctrl.setSelectionRange)
 {
  ctrl.focus();
  ctrl.setSelectionRange(pos,pos);
 }
 else if (ctrl.createTextRange)
 {
  var range = ctrl.createTextRange();
  range.collapse(true);
  range.moveEnd('character', pos);
  range.moveStart('character', pos);
  range.select();
 }
}

Your code is

urlpatterns = [
    url(r'^$', 'myapp.views.home'),
    url(r'^contact/$', 'myapp.views.contact'),
    url(r'^login/$', 'django.contrib.auth.views.login'),
]

change it to following as you're importing include() function :

urlpatterns = [
    url(r'^$', views.home),
    url(r'^contact/$', views.contact),
    url(r'^login/$', views.login),
]

Simply enter these into Windows command prompt.

FilenameUtils.wildcardMatch

See Apache javadoc here. It matches the wildcard with the filename. So you can use this method for your comparisons.

I think a lot of people answer this question "no" because JavaScript does not implement classes, in the traditional OO sense. Unfortunately (IMHO), that is coming in ECMAScript 4. Until then, viva la prototype! :-)

For this reason better is if you use this data from CSS or JSON file data, and then with this data setting new state with this.state({width: "some value",height:"some value" }); or writing code who use data of width screen data in self work if you wish responsive show images

For pushing a single tag: git push <reponame> <tagname>

For instance, git push production 1.0.0. Tags are not bound to branches, they are bound to commits.

When you want to have the tag's content in the master branch, do that locally on your machine. I would assume that you continued developing in your local master branch. Then just a git push origin master should suffice.

select to.chargeid,t0.po,i.chargetype from invoice i
inner join
(select chargeid,max(servicemonth)po from invoice 
group by chargeid)t0
on i.chargeid=t0.chargeid

The above query will work if the distinct charge id has different chargetype combinations.Hope this simple query helps with little performance time into consideration...

Use set difference

>>> z = list(set(x) - set(y))
>>> z
[0, 8, 2, 4, 6]

Or you might just have x and y be sets so you don't have to do any conversions.

Here is a repo the demonstrates serving a custom font with Rails 5.2 that works on Heroku. It goes further and optimizes serving the fonts to be as fast as possible according to https://www.webpagetest.org/

https://github.com/nzoschke/edgecors

To start I picked pieces from answers above. For Rails 5.2+ you shouldn't need extra asset pipeline config.

Asset Pipeline and SCSS

• Place fonts in app/assets/fonts
• Place the @font-face declaration in an scss file and use the font-url helper

From app/assets/stylesheets/welcome.scss:

@font-face {
  font-family: 'Inconsolata';
  src: font-url('Inconsolata-Regular.ttf') format('truetype');
  font-weight: normal;
  font-style: normal;
}

body {
  font-family: "Inconsolata";
  font-weight: bold;
}

Serve from CDN with CORS

I'm using CloudFront, added with the Heroku Edge addon.

First configure a CDN prefix and default Cache-Control headers in production.rb:

Rails.application.configure do
  # e.g. https://d1unsc88mkka3m.cloudfront.net
  config.action_controller.asset_host = ENV["EDGE_URL"]

  config.public_file_server.headers = {
    'Cache-Control' => 'public, max-age=31536000'
  }
end

If you try to access the font from the herokuapp.com URL to the CDN URL, you will get a CORS error in your browser:

Access to font at 'https://d1unsc88mkka3m.cloudfront.net/assets/Inconsolata-Regular.ttf' from origin 'https://edgecors.herokuapp.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. edgecors.herokuapp.com/ GET https://d1unsc88mkka3m.cloudfront.net/assets/Inconsolata-Regular.ttf net::ERR_FAILED

So configure CORS to allow access to the font from Heroku to the CDN URL:

module EdgeCors
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.2

    config.middleware.insert_after ActionDispatch::Static, Rack::Deflater

    config.middleware.insert_before 0, Rack::Cors do
      allow do
        origins %w[
          http://edgecors.herokuapp.com
          https://edgecors.herokuapp.com
        ]
        resource "*", headers: :any, methods: [:get, :post, :options]
      end
    end
  end
end

Serve gzip Font Asset

The asset pipeline builds a .ttf.gz file but doesn't serve it. This monkey patch changes the asset pipeline gzip whitelist to a blacklist:

require 'action_dispatch/middleware/static'

ActionDispatch::FileHandler.class_eval do
  private

    def gzip_file_path(path)
      return false if ['image/png', 'image/jpeg', 'image/gif'].include? content_type(path)
      gzip_path = "#{path}.gz"
      if File.exist?(File.join(@root, ::Rack::Utils.unescape_path(gzip_path)))
        gzip_path
      else
        false
      end
    end
end

The ultimate result is a custom font file in app/assets/fonts served from a long-lived CloudFront cache.

Disclamers:

• This answer is late half a year :D
• I'm a heavy tmux user
• You have to run your shell in tmux for this to work

When running an interactive shell in tmux, you can easily access the data currently displayed on a terminal. Let's take a look at some interesting commands:

• tmux capture-pane: this one copies the displayed data to one of the tmux's internal buffers. It can copy the history that's currently not visible, but we're not interested in that now
• tmux list-buffers: this displays the info about the captured buffers. The newest one will have the number 0.
• tmux show-buffer -b (buffer num): this prints the contents of the given buffer on a terminal
• tmux paste-buffer -b (buffer num): this pastes the contents of the given buffer as input

Yeah, this gives us a lot of possibilities now :) As for me, I set up a simple alias: alias L="tmux capture-pane; tmux showb -b 0 | tail -n 3 | head -n 1" and now every time I need to access the last line i simply use $(L) to get it.

This is independent of the output stream the program uses (be it stdin or stderr), the printing method (ncurses, etc.) and the program's exit code - the data just needs to be displayed.

A good example of this casting is using *= or /=

byte b = 10;
b *= 5.7;
System.out.println(b); // prints 57

or

byte b = 100;
b /= 2.5;
System.out.println(b); // prints 40

or

char ch = '0';
ch *= 1.1;
System.out.println(ch); // prints '4'

or

char ch = 'A';
ch *= 1.5;
System.out.println(ch); // prints 'a'

In python 3.8+ you can do :

(a:=a+1) #same as ++a (increment, then return new value)
(a:=a+1)-1 #same as a++ (return the incremented value -1) (useless)

You can do a lot of thinks with this.

>>> a = 0
>>> while (a:=a+1) < 5:
    print(a)

    
1
2
3
4

Or if you want write somthing with more sophisticated syntaxe (the goal is not optimization):

>>> del a
>>> while (a := (a if 'a' in locals() else 0) + 1) < 5:
    print(a)

    
1
2
3
4

It will return 0 even if 'a' doesn't exist without errors, and then will set it to 1

You could use the same mechanism as git submodule init uses itself, namely, look at .gitmodules. This files enumerates each submodule path and the URL it refers to.

For example, from root of repository, cat .gitmodules will print contents to the screen (assuming you have cat).

Because .gitmodule files have the Git configuration format, you can use git config to parse those files:

git config --file .gitmodules --name-only --get-regexp path

Would show you all submodule entries, and with

git config --file .gitmodules --get-regexp path | awk '{ print $2 }'

you would only get the submodule path itself.

Try this example and see if it fits your needs, there are three main aspects to it.

1. Line.Stretch is set to fill.

2. For horizontal lines the VerticalAlignment of the line is set Bottom, and for VerticalLines the HorizontalAlignment is set to Right.

3. We then need to tell the line how many rows or columns to span, this is done by binding to either RowDefinitions or ColumnDefintions count property.

I find a good way of achieving this at Remove browse button from input=file.

The rationale behind this solution is that it creates a transparent input=file control and creates an layer visible to the user below the file control. The z-index of the input=file will be higher than the layer.

With this, it appears that the layer is the file control itself. But actually when you clicks on it, the input=file is the one clicked and the dialog for choosing file will appear.

I already had committed the folder before and want to remove the directory in the history as well.

I did the following:

Add folder to .gitignore:

echo Folder_Name/ >> .gitignore

Remove from all commits:

git filter-branch --index-filter 'git rm -rf --cached --ignore-unmatch Folder_Name/' --prune-empty --tag-name-filter cat -- --all

remove the refs from the old commits:

git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d

Ensure all old refs are fully removed

rm -Rf .git/logs .git/refs/original

Perform a garbage collection

git gc --prune=all --aggressive

push you changes to the online repository:

git push

You are done here.

But you can to the following to push all the changes to all branches with: But be careful with this command!

git push origin --all --force
git push origin --tags --force

After that the folder was removed from git, but was not deleted from local disk.

This is an alternative cheat if you are familiar with Python or R, and your table can fit into memory.

Import the SQL table into Python or R and then export from there as a CSV and you'll get the column names as well as the data.

Here's how I do it using R, requires the RMySQL library:

db <- dbConnect(MySQL(), user='user', password='password', dbname='myschema', host='localhost')

query <- dbSendQuery(db, "select * from mytable")
dataset <- fetch(query, n=-1)

write.csv(dataset, 'mytable_backup.csv')

It's a bit of a cheat but I found this was a quick workaround when my number of columns was too long to use the concat method above. Note: R will add a 'row.names' column at the start of the CSV so you'll want to drop that if you do need to rely on the CSV to recreate the table.

I wanted to comment out a lot of lines in some config file on a server that only had vi (no nano), so visual method was cumbersome as well Here's how i did that.

1. Open file vi file
2. Display line numbers :set number! or :set number
3. Then use the line numbers to replace start-of-line with "#", how?

:35,77s/^/#/

Note: the numbers are inclusive, lines from 35 to 77, both included will be modified.

To uncomment/undo that, simply use :35,77s/^#//

If you want to add a text word as a comment after every line of code, you can also use:

:35,77s/$/#test/ (for languages like Python)

:35,77s/;$/;\/\/test/ (for languages like Java)

The documentation says:

bytes(int) -> bytes object of size given by the parameter
              initialized with null bytes

The sequence:

b'3\r\n'

It is the character '3' (decimal 51) the character '\r' (13) and '\n' (10).

Therefore, the way would treat it as such, for example:

>>> bytes([51, 13, 10])
b'3\r\n'

>>> bytes('3', 'utf8') + b'\r\n'
b'3\r\n'

>>> n = 3
>>> bytes(str(n), 'ascii') + b'\r\n'
b'3\r\n'

Tested on IPython 1.1.0 & Python 3.2.3

Why not using exit codes? If a git repository exists in the current directory, then git branch and git tag commands return exit code of 0; otherwise, a non-zero exit code will be returned. This way, you can determine if a git repository exist or not. Simply, you can run:

git tag > /dev/null 2>&1 && [ $? -eq 0 ]

Advantage: Flexibe. It works for both bare and non-bare repositories, and in sh, zsh and bash.

Explanation

1. git tag: Getting tags of the repository to determine if exists or not.
2. > /dev/null 2>&1: Preventing from printing anything, including normal and error outputs.
3. [ $? -eq 0 ]: Check if the previous command returned with exit code 0 or not. As you may know, every non-zero exit means something bad happened. $? gets the exit code of the previous command, and [, -eq and ] perform the comparison.

As an example, you can create a file named check-git-repo with the following contents, make it executable and run it:

#!/bin/sh

if git tag > /dev/null 2>&1 && [ $? -eq 0 ]; then
    echo "Repository exists!";
else
    echo "No repository here.";

0 through 340282366920938463463374607431768211455 (decimal) or 
0 through 11111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111 (binary, base 2) or 
0 through 91"<b.PX48m!wVmVA?1y (base 95)

So yes, min 20 characters long, which is actually wasting more than 4.25 bits, so you can be just as efficient using smaller bases than 95 as well; base 85 being the smallest possible one that still fits into 20 chars:

0 through -r54lj%NUUO[Hi$c2ym0 (base 85, using 0-9A-Za-z!"#$%&'()*+,- chars)

I took Fredrik's method and modified the return type.

This way, the method supports deferred execution like other LINQ methods.

EDIT: If this wasn't clear, any usage of this method must end with ToList() or any other way to force the method to work on the complete enumerable. Otherwise, the action would not be performed!

public static IEnumerable<T> ForEach<T>(this IEnumerable<T> enumeration, Action<T> action)
{
    foreach (T item in enumeration)
    {
        action(item);
        yield return item;
    }
}

And here's the test to help see it:

[Test]
public void TestDefferedExecutionOfIEnumerableForEach()
{
    IEnumerable<char> enumerable = new[] {'a', 'b', 'c'};

    var sb = new StringBuilder();

    enumerable
        .ForEach(c => sb.Append("1"))
        .ForEach(c => sb.Append("2"))
        .ToList();

    Assert.That(sb.ToString(), Is.EqualTo("121212"));
}

If you remove the ToList() in the end, you will see the test failing since the StringBuilder contains an empty string. This is because no method forced the ForEach to enumerate.

.communicate() writes input (there is no input in this case so it just closes subprocess' stdin to indicate to the subprocess that there is no more input), reads all output, and waits for the subprocess to exit.

The exception EOFError is raised in the child process by raw_input() (it expected data but got EOF (no data)).

p.stdout.read() hangs forever because it tries to read all output from the child at the same time as the child waits for input (raw_input()) that causes a deadlock.

To avoid the deadlock you need to read/write asynchronously (e.g., by using threads or select) or to know exactly when and how much to read/write, for example:

from subprocess import PIPE, Popen

p = Popen(["python", "-u", "1st.py"], stdin=PIPE, stdout=PIPE, bufsize=1)
print p.stdout.readline(), # read the first line
for i in range(10): # repeat several times to show that it works
    print >>p.stdin, i # write input
    p.stdin.flush() # not necessary in this case
    print p.stdout.readline(), # read output

print p.communicate("n\n")[0], # signal the child to exit,
                               # read the rest of the output, 
                               # wait for the child to exit

Note: it is a very fragile code if read/write are not in sync; it deadlocks.

Beware of block-buffering issue (here it is solved by using "-u" flag that turns off buffering for stdin, stdout in the child).

bufsize=1 makes the pipes line-buffered on the parent side.

It is not possible to get the height of the screen from CSS. However, using since CSS3 you can use media queries to control the display of the template as per the resolution.

If you want to code on the basis of height using media queries, you can define style-sheet and call it like this.

<link rel="stylesheet" media="screen and (device-height: 600px)" />

If you have a partial page form for both editing and adding, then the trick I use to default value to 0 is to do the following:

@Html.TextBox("Age", Model.Age ?? 0)

That way it will be 0 if unset or the actual age if it exists.

[print(a) for a in list] will give a bunch of None types at the end though it prints out all the items

Absent of any other information, I'll assume the following XML:

<group>
    <item>
        <id>item 1</id>
        <CategoryName>blue</CategoryName>
    </item>
    <item>
        <id>item 2</id>
        <CategoryName></CategoryName>
    </item>
    <item>
        <id>item 3</id>
    </item>
    ...
</group>

A sample use case would look like:

<xsl:for-each select="/group/item">
    <xsl:if test="CategoryName">
        <!-- will be instantiated for item #1 and item #2 -->
    </xsl:if>
    <xsl:if test="not(CategoryName)">
        <!-- will be instantiated for item #3 -->
    </xsl:if>
    <xsl:if test="CategoryName != ''">
        <!-- will be instantiated for item #1 -->
    </xsl:if>
    <xsl:if test="CategoryName = ''">
        <!-- will be instantiated for item #2 -->
    </xsl:if>
</xsl:for-each>

adding to CMS's answer, this is a more generic approach of toggle_visibility I've just used myself:

function toggle_visibility(className,display) {
   var elements = getElementsByClassName(document, className),
       n = elements.length;
   for (var i = 0; i < n; i++) {
     var e = elements[i];

     if(display.length > 0) {
       e.style.display = display;
     } else {
       if(e.style.display == 'block') {
         e.style.display = 'none';
       } else {
         e.style.display = 'block';
       }
     }
  }
}

When you make a call to using namespace <some_namespace>; all symbols in that namespace will become visible without adding the namespace prefix. A symbol may be for instance a function, class or a variable.

E.g. if you add using namespace std; you can write just cout instead of std::cout when calling the operator cout defined in the namespace std.

This is somewhat dangerous because namespaces are meant to be used to avoid name collisions and by writing using namespace you spare some code, but loose this advantage. A better alternative is to use just specific symbols thus making them visible without the namespace prefix. Eg:

#include <iostream>
using std::cout;

int main() {
  cout << "Hello world!";
  return 0;
}

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Variant

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    rowNum = Application.Match(aNumber, rng, 0)

    If Not IsError(rowNum) Then
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

The keyboard height depends on the model, the QuickType bar, user settings... The best approach is calculate dinamically:

Swift 3.0

    var heightKeyboard : CGFloat?

    override func viewWillAppear(_ animated: Bool) {
            super.viewWillAppear(animated)
            NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardShown(notification:)), name: NSNotification.Name.UIKeyboardDidShow, object: nil)
    }

    func keyboardShown(notification: NSNotification) {
           if let infoKey  = notification.userInfo?[UIKeyboardFrameEndUserInfoKey],
               let rawFrame = (infoKey as AnyObject).cgRectValue {
               let keyboardFrame = view.convert(rawFrame, from: nil)
               self.heightKeyboard = keyboardFrame.size.height
               // Now is stored in your heightKeyboard variable
           }
    }

This function (ManagementQuery) works on Windows XP and later:

private static string ManagementQuery(string query, string parameter, string scope = null) {
    string result = string.Empty;
    var searcher = string.IsNullOrEmpty(scope) ? new ManagementObjectSearcher(query) : new ManagementObjectSearcher(scope, query);
    foreach (var os in searcher.Get()) {
        try {
            result = os[parameter].ToString();
        }
        catch {
            //ignore
        }

        if (!string.IsNullOrEmpty(result)) {
            break;
        }
    }

    return result;
}

Usage:

Console.WriteLine(BytesToMb(Convert.ToInt64(ManagementQuery("SELECT TotalPhysicalMemory FROM Win32_ComputerSystem", "TotalPhysicalMemory", "root\\CIMV2"))));

I've had success with express and editing the res.header. Mine matches yours pretty closely but I have a different Allow-Headers as noted below:

rand() will return numbers between 0 and RAND_MAX, which is at least 32767.

If you want to get a number within a range, you can just use modulo.

int value = rand() % 66; // 0-65

For more accuracy, check out this article. It discusses why modulo is not necessarily good (bad distributions, particularly on the high end), and provides various options.

The following code worked for me:

echo userInput

The standard technique in plugin form would look something like this:

(function($) {
    $.fn.goTo = function() {
        $('html, body').animate({
            scrollTop: $(this).offset().top + 'px'
        }, 'fast');
        return this; // for chaining...
    }
})(jQuery);

Then you could just say $('#div_element2').goTo(); to scroll to <div id="div_element2">. Options handling and configurability is left as an exercise for the reader.

Problem statement

Problem occurs when we want to import CommonJS module into ES6 module codebase.

Before these flags we had to import CommonJS modules with star (* as something) import:

// node_modules/moment/index.js
exports = moment

// index.ts file in our app
import * as moment from 'moment'
moment(); // not compliant with es6 module spec

// transpiled js (simplified):
const moment = require("moment");
moment();

We can see that * was somehow equivalent to exports variable. It worked fine, but it wasn't compliant with es6 modules spec. In spec, the namespace record in star import (moment in our case) can be only a plain object, not callable (moment() is not allowed).

Solution

With flag esModuleInterop we can import CommonJS modules in compliance with es6 modules spec. Now our import code looks like this:

// index.ts file in our app
import moment from 'moment'
moment(); // compliant with es6 module spec

// transpiled js with esModuleInterop (simplified):
const moment = __importDefault(require('moment'));
moment.default();

It works and it's perfectly valid with es6 modules spec, because moment is not namespace from star import, it's default import.

But how does it work? As you can see, because we did a default import, we called the default property on a moment object. But we didn't declare a default property on the exports object in the moment library. The key is the __importDefault function. It assigns module (exports) to the default property for CommonJS modules:

var __importDefault = (this && this.__importDefault) || function (mod) {
    return (mod && mod.__esModule) ? mod : { "default": mod };
};

As you can see, we import es6 modules as they are, but CommonJS modules are wrapped into an object with the default key. This makes it possible to import defaults on CommonJS modules.

__importStar does the similar job - it returns untouched esModules, but translates CommonJS modules into modules with a default property:

// index.ts file in our app
import * as moment from 'moment'

// transpiled js with esModuleInterop (simplified):
const moment = __importStar(require("moment"));
// note that "moment" is now uncallable - ts will report error!

var __importStar = (this && this.__importStar) || function (mod) {
    if (mod && mod.__esModule) return mod;
    var result = {};
    if (mod != null) for (var k in mod) if (Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
    result["default"] = mod;
    return result;
};

Synthetic imports

And what about allowSyntheticDefaultImports - what is it for? Now the docs should be clear:

Allow default imports from modules with no default export. This does not affect code emit, just typechecking.

In moment typings we don't have specified default export, and we shouldn't have, because it's available only with flag esModuleInterop on. So allowSyntheticDefaultImports will not report an error if we want to import default from a third-party module which doesn't have a default export.

import json

with open('tokenler.json', 'w') as file:
     file.write(json.dumps(mydict, ensure_ascii=False))

In Spark 2.0 you can also configure it dynamically for your application using setLogLevel:

    from pyspark.sql import SparkSession
    spark = SparkSession.builder.\
        master('local').\
        appName('foo').\
        getOrCreate()
    spark.sparkContext.setLogLevel('WARN')

In the pyspark console, a default spark session will already be available.

say you define the static getFactorial function inside a CodeController

then this is the way you need to call a static function, because static properties and methods exists with in the class, not in the objects created using the class.

CodeController::getFactorial($index);

----------------UPDATE----------------

To best practice I think you can put this kind of functions inside a separate file so you can maintain with more easily.

to do that

create a folder inside app directory and name it as lib (you can put a name you like).

this folder to needs to be autoload to do that add app/lib to composer.json as below. and run the composer dumpautoload command.

"autoload": {
    "classmap": [
                "app/commands",
                "app/controllers",
                ............
                "app/lib"
    ]
},

then files inside lib will autoloaded.

then create a file inside lib, i name it helperFunctions.php

inside that define the function.

if ( ! function_exists('getFactorial'))
{

    /**
     * return the factorial of a number
     *
     * @param $number
     * @return string
     */
    function getFactorial($date)
    {
        $fact = 1;

        for($i = 1; $i <= $num ;$i++)
            $fact = $fact * $i;

        return $fact;

     }
}

and call it anywhere within the app as

$fatorial_value = getFactorial(225);

Here is my implementation for calculating the week number in JavaScript. corrected for summer and winter time offsets as well. I used the definition of the week from this article: ISO 8601

Weeks are from mondays to sunday, and january 4th is always in the first week of the year.

// add get week prototype functions
// weeks always start from monday to sunday
// january 4th is always in the first week of the year
Date.prototype.getWeek = function () {
    year = this.getFullYear();
    var currentDotw = this.getWeekDay();
    if (this.getMonth() == 11 && this.getDate() - currentDotw > 28) {
        // if true, the week is part of next year 
        return this.getWeekForYear(year + 1);
    }
    if (this.getMonth() == 0 && this.getDate() + 6 - currentDotw < 4) {
        // if true, the week is part of previous year
        return this.getWeekForYear(year - 1);
    }
    return this.getWeekForYear(year);
}

// returns a zero based day, where monday = 0
// all weeks start with monday
Date.prototype.getWeekDay = function () {
    return  (this.getDay() + 6) % 7;
}

// corrected for summer/winter time
Date.prototype.getWeekForYear = function (year) {
    var currentDotw = this.getWeekDay();
    var fourjan = new Date(year, 0, 4);
    var firstDotw = fourjan.getWeekDay();
    var dayTotal = this.getDaysDifferenceCorrected(fourjan) // the difference in days between the two dates.
    // correct for the days of the week
    dayTotal += firstDotw; // the difference between the current date and the first monday of the first week, 
    dayTotal -= currentDotw; // the difference between the first monday and the current week's monday
    // day total should be a multiple of 7 now
    var weeknumber = dayTotal / 7 + 1; // add one since it gives a zero based week number.
    return weeknumber;
}

// corrected for timezones and offset
Date.prototype.getDaysDifferenceCorrected = function (other) {
    var millisecondsDifference = (this - other);
    // correct for offset difference. offsets are in minutes, the difference is in milliseconds
    millisecondsDifference += (other.getTimezoneOffset()- this.getTimezoneOffset()) * 60000;
    // return day total. 1 day is 86400000 milliseconds, floor the value to return only full days
    return Math.floor(millisecondsDifference / 86400000);
}

for testing i used the following JavaScript tests in Qunit

var runweekcompare = function(result, expected) {
    equal(result, expected,'Week nr expected value: ' + expected + ' Actual value: ' + result);
}

test('first week number test', function () {
    expect(5);
    var temp = new Date(2016, 0, 4); // is the monday of the first week of the year
    runweekcompare(temp.getWeek(), 1);
    var temp = new Date(2016, 0, 4, 23, 50); // is the monday of the first week of the year
    runweekcompare(temp.getWeek(), 1);
    var temp = new Date(2016, 0, 10, 23, 50); // is the sunday of the first week of the year
    runweekcompare(temp.getWeek(), 1);
    var temp = new Date(2016, 0, 11, 23, 50); // is the second week of the year
    runweekcompare(temp.getWeek(), 2);
    var temp = new Date(2016, 1, 29, 23, 50); // is the 9th week of the year
    runweekcompare(temp.getWeek(), 9);
});

test('first day is part of last years last week', function () {
    expect(2);
    var temp = new Date(2016, 0, 1, 23, 50); // is the first last week of the previous year
    runweekcompare(temp.getWeek(), 53);
    var temp = new Date(2011, 0, 2, 23, 50); // is the first last week of the previous year
    runweekcompare(temp.getWeek(), 52);
});

test('last  day is part of next years first week', function () {
    var temp = new Date(2013, 11, 30); // is part of the first week of 2014
    runweekcompare(temp.getWeek(), 1);
});

test('summer winter time change', function () {
    expect(2);
    var temp = new Date(2000, 2, 26); 
    runweekcompare(temp.getWeek(), 12);
    var temp = new Date(2000, 2, 27); 
    runweekcompare(temp.getWeek(), 13);
});

test('full 20 year test', function () {
    //expect(20 * 12 * 28 * 2);
    for (i = 2000; i < 2020; i++) {
        for (month = 0; month < 12; month++) {
            for (day = 1; day < 29 ; day++) {
                var temp = new Date(i, month, day);
                var expectedweek = temp.getWeek();
                var temp2 = new Date(i, month, day, 23, 50);
                var resultweek = temp.getWeek();
                equal(expectedweek, Math.round(expectedweek), 'week number whole number expected ' + Math.round(expectedweek) + ' resulted week nr ' + expectedweek);
                equal(resultweek, expectedweek, 'Week nr expected value: ' + expectedweek + ' Actual value: ' + resultweek + ' for year ' + i + ' month ' + month + ' day ' + day);
            }
        }
    }
});

Heres one more from rails console

ActiveRecord::Migration.remove_column(:table_name, :column_name)

It's simple. Suppose you want to move from A to C

if there's only one disk, just move it.

If there's more than one disk, do

• move all disks (n-1 disks), except the bottom one from A to B
• move the bottom disk from A to C
• move the n-1 disks from the first step from A to C

Keep in mind that, when moving the n-1 disks, the nth won't be a problem at all (once it is bigger than all the others)

Note that moving the n-1 disks recurs on the same problem again, until n-1 = 1, in which case you'll be on the first if (where you should just move it).

For floating point numbers there is a standard (IEEE754): floats are 32 bit and doubles are 64. This is a hardware standard, not a C++ standard, so compilers could theoretically define float and double to some other size, but in practice I've never seen an architecture that used anything different.

This is also fine:

It looks like you want to convert the list to a list of numbers

>>> foo = ['-1.2', '0.0', '1']
>>> bar = map(float, foo)
>>> bar
[-1.2, 0.0, 1.0]
>>> min(bar)
-1.2

or if it really is strings you want, that you want to use min's key argument

>>> foo = ['-1.2', '0.0', '1']
>>> min(foo, key=float)
'-1.2'

At the answer from @squicc if you amend this line: $topDir = Get-ChildItem -directory "C:\test" with -force then you will be able to see the hidden directories also. Without this, the size will be different when you run the solution from inside or outside the folder.

Following worked for me:

1. Uninstall the previously installed ‘Microsoft Online Service Sign-in Assistant’ and ‘Windows Azure Active Directory Module for Windows PowerShell’.
2. Install 64-bit versions of ‘Microsoft Online Service Sign-in Assistant’ and ‘Windows Azure Active Directory Module for Windows PowerShell’. https://littletalk.wordpress.com/2013/09/23/install-and-configure-the-office-365-powershell-cmdlets/

If you get the following error In order to install Windows Azure Active Directory Module for Windows PowerShell, you must have Microsoft Online Services Sign-In Assistant version 7.0 or greater installed on this computer, then install the Microsoft Online Services Sign-In Assistant for IT Professionals BETA: http://www.microsoft.com/en-us/download/details.aspx?id=39267

3. Copy the folders called MSOnline and MSOnline Extended from the source

C:\Windows\System32\WindowsPowerShell\v1.0\Modules\

to the folder

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Modules\

https://stackoverflow.com/a/16018733/5810078.

(But I have actually copied all the possible files from

C:\Windows\System32\WindowsPowerShell\v1.0\

to

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\

(For copying you need to alter the security permissions of that folder))

A naive approach could look like this:

#include <map>
#include <sstream>
#include <stdexcept>
#include <string>

std::map<std::string, std::string> options; // global?

void parse(std::istream & cfgfile)
{
    for (std::string line; std::getline(cfgfile, line); )
    {
        std::istringstream iss(line);
        std::string id, eq, val;

        bool error = false;

        if (!(iss >> id))
        {
            error = true;
        }
        else if (id[0] == '#')
        {
            continue;
        }
        else if (!(iss >> eq >> val >> std::ws) || eq != "=" || iss.get() != EOF)
        {
            error = true;
        }

        if (error)
        {
            // do something appropriate: throw, skip, warn, etc.
        }
        else
        {
            options[id] = val;
        }
    }
}

Now you can access each option value from the global options map anywhere in your program. If you want castability, you could make the mapped type a boost::variant.

it's easy with the id of the div container : (I didn't put the close button inside the <a> because that's does work properly on all browser.

<div id="myDiv">
<button class="close" onclick="document.getElementById('myDiv').style.display='none'" >Close</button>
<a class="fragment" href="http://google.com">
    <div>
    <img src ="http://placehold.it/116x116" alt="some description"/> 
    <h3>the title will go here</h3>
        <h4> www.myurlwill.com </h4>
    <p class="text">
        this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etcthis is a short description yada yada peanuts etc 
    </p>
</div>
</a>
</div>

Here is an example that shows the differences, which will help with the explanation.

var s1 = new String("Avoid newing things where possible");
var s2 = "A string, in TypeScript of type 'string'";
var s3: string;

String is the JavaScript String type, which you could use to create new strings. Nobody does this as in JavaScript the literals are considered better, so s2 in the example above creates a new string without the use of the new keyword and without explicitly using the String object.

string is the TypeScript string type, which you can use to type variables, parameters and return values.

Additional notes...

Currently (Feb 2013) Both s1 and s2 are valid JavaScript. s3 is valid TypeScript.

Use of String. You probably never need to use it, string literals are universally accepted as being the correct way to initialise a string. In JavaScript, it is also considered better to use object literals and array literals too:

var arr = []; // not var arr = new Array();
var obj = {}; // not var obj = new Object();

If you really had a penchant for the string, you could use it in TypeScript in one of two ways...

var str: String = new String("Hello world"); // Uses the JavaScript String object
var str: string = String("Hello World"); // Uses the TypeScript string type

Onchange is only fired when user enters something by keyboard. A possible workarround could be to first focus the textfield and then change it.

But why not fetch the event when the user clicks on a date? There already must be some javascript.

try this

var value = iterate('tr.item span.value');
var quantity = iterate('tr.item span.quantity');

function iterate(selector)
{
  var result = '';
  if ($(selector))
  {
    $(selector).each(function ()
    {
      if (result == '')
      {
        result = $(this).html();
      }
      else
      {
        result = result + "," + $(this).html();
      }
    });
  }
}

Try this:

package main

import (
  "io"; 
  )


func main() {
  contents,_ := io.ReadFile("filename");
  println(string(contents));
  io.WriteFile("filename", contents, 0644);
}

ASP.net MVC go to Content- Site.css and remove or comment this line:

input,
select,
textarea {
    /*max-width: 280px;*/
}

I was also developing a similar application. I was also getting not found error even though the file was there. This solve my problem. I mention my download folder in 'static_folder':

app = Flask(__name__,static_folder='pdf')

My code for the download is as follows:

@app.route('/pdf/<path:filename>', methods=['GET', 'POST'])
def download(filename):    
    return send_from_directory(directory='pdf', filename=filename)

This is how I am calling my file from html.

<a class="label label-primary" href=/pdf/{{  post.hashVal }}.pdf target="_blank"  style="margin-right: 5px;">Download pdf </a>
<a class="label label-primary" href=/pdf/{{  post.hashVal }}.png target="_blank"  style="margin-right: 5px;">Download png </a>

I located the Facebook's console buster script using Chrome developer tools. Here is the script with minor changes for readability. I have removed the bits that I could not understand:

Object.defineProperty(window, "console", {
    value: console,
    writable: false,
    configurable: false
});

var i = 0;
function showWarningAndThrow() {
    if (!i) {
        setTimeout(function () {
            console.log("%cWarning message", "font: 2em sans-serif; color: yellow; background-color: red;");
        }, 1);
        i = 1;
    }
    throw "Console is disabled";
}

var l, n = {
        set: function (o) {
            l = o;
        },
        get: function () {
            showWarningAndThrow();
            return l;
        }
    };
Object.defineProperty(console, "_commandLineAPI", n);
Object.defineProperty(console, "__commandLineAPI", n);

With this, the console auto-complete fails silently while statements typed in console will fail to execute (the exception will be logged).

• Object.defineProperty
• Object.getOwnPropertyDescriptor
• Chrome's console.log function (for tips on formatting output)

Change the rule on your <a> element from:

.navigation ul a {
    color: #000;
    display: block;
    padding: 0 65px 0 0;
    text-decoration: none;
}?

to

.navigation ul a {
    color: #000;
    display: block;
    padding: 0 65px 0 0;
    text-decoration: none;
    width:100%;
    text-align:center;
}?

Just add two new rules (width:100%; and text-align:center;). You need to make the anchor expand to take up the full width of the list item and then text-align center it.

TL;DR

Just returning response()->json($promotion) won't solve the issue in this question. $promotion is an Eloquent object, which Laravel will automatically json_encode for the response. The json encoding is failing because of the img property, which is a PHP stream resource, and cannot be encoded.

Details

Whatever you return from your controller, Laravel is going to attempt to convert to a string. When you return an object, the object's __toString() magic method will be invoked to make the conversion.

Therefore, when you just return $promotion from your controller action, Laravel is going to call __toString() on it to convert it to a string to display.

On the Model, __toString() calls toJson(), which returns the result of json_encode. Therefore, json_encode is returning false, meaning it is running into an error.

Your dd shows that your img attribute is a stream resource. json_encode cannot encode a resource, so this is probably causing the failure. You should add your img attribute to the $hidden property to remove it from the json_encode.

class Promotion extends Model
{
    protected $hidden = ['img'];

    // rest of class
}

Adding bootstrap current version 4 to angular:

1/ First you have to install those:

npm install jquery --save
npm install popper.js --save
npm install bootstrap --save

2/ Then add the needed script files to scripts in angular.json:

"scripts": [
  "node_modules/jquery/dist/jquery.slim.js",
  "node_modules/popper.js/dist/umd/popper.js",
  "node_modules/bootstrap/dist/js/bootstrap.js"
],

3/Finally add the Bootstrap CSS to the styles array in angular.json:

"styles": [
  "node_modules/bootstrap/dist/css/bootstrap.css",
  "src/styles.css"
],`

check this link

If the caller is another project, you should write the config in caller project not the called one.

New Date(number) returns a date that's number milliseconds after 1 Jan 1970. Odds are you date format isn't showing hours, minutes, and seconds for you to see that it's just a little bit after 1 Jan 1970.

You need to parse the date according to the correct parsing routing. I don't know what a 1220227200 is, but if it's seconds after 1 JAN 1970, then multiply it to yield milliseconds. If it is not, then convert it in some manner to milliseconds after 1970 (if you want to continue to use java.util.Date).

I solved the problem for me by addressing also the worksheet first:

ws.rows(x & ":" & y).Select

without the reference to the worksheet (ws) I got an error.

<form onsubmit="return confirm('Are you sure?');" />

works well for forms. Form-specific question: JavaScript Form Submit - Confirm or Cancel Submission Dialog Box

Just run this command

EXEC sp_columns 'Your Table Name'

The CompileSdkVersion is the version of the SDK platform your app works with for compilation, etc DURING the development process (you should always use the latest) This is shipped with the API version you are using

You will see this in your build.gradle file:

targetSdkVersion: contains the info your app ships with AFTER the development process to the app store that allows it to TARGET the SPECIFIED version of the Android platform. Depending on the functionality of your app, it can target API versions lower than the current.For instance, you can target API 18 even if the current version is 23.

Take a good look at this official Google page.

The default value of end is \n meaning that after the print statement it will print a new line. So simply stated end is what you want to be printed after the print statement has been executed

Eg: - print ("hello",end=" +") will print hello +

Here is an example that does a union between two completely unrelated tables: the Student and the Products table. It generates an output that is 4 columns:

select
        FirstName as Column1,
        LastName as Column2,
        email as Column3,
        null as Column4
    from
        Student
union
select
        ProductName as Column1,
        QuantityPerUnit as Column2,
        null as Column3,
        UnitsInStock as Column4
    from
        Products

Obviously you'll tweak this for your own environment...

@Paul Cavacas, I had the same issue and I solved by setting the Input() decorator above the getter.

  @Input('allowDays')
  get in(): any {
    return this._allowDays;
  }

  //@Input('allowDays')
  // not working
  set in(val) {
    console.log('allowDays = '+val);
    this._allowDays = val;
  }

It's been a little while since I coded with selenium, but your code looks ok to me. One thing to note is that if the element is not found, but the timeout is passed, I think the code will continue to execute. So you can do something like this:

boolean exists = driver.findElements(By.xpath("//*[@id='someID']")).size() != 0

What does the above boolean return? And are you sure selenium actually navigates to the expected page? (That may sound like a silly question but are you actually watching the pages change... selenium can be run remotely you know...)

Rather than escaping all characters in a string that have particular significance in the pattern syntax given that you are using a leading wildcard in the pattern it is quicker and easier just to do.

SELECT * 
FROM YourTable
WHERE CHARINDEX(@myString , YourColumn) > 0

In cases where you are not using a leading wildcard the approach above should be avoided however as it cannot use an index on YourColumn.

Additionally in cases where the optimum execution plan will vary according to the number of matching rows the estimates may be better when using LIKE with the square bracket escaping syntax when compared to both CHARINDEX and the ESCAPE keyword.

You can user pagination of Instagram PHP API: https://github.com/cosenary/Instagram-PHP-API/wiki/Using-Pagination

Something like that:

    $Instagram = new MetzWeb\Instagram\Instagram(array(
        "apiKey"      => IG_APP_KEY,
        "apiSecret"   => IG_APP_SECRET,
        "apiCallback" => IG_APP_CALLBACK
    ));
    $Instagram->setSignedHeader(true);

    $pictures = $Instagram->getUserMedia(123);
    do {

        foreach ($pictures->data as $picture_data):

            echo '<img src="'.$picture_data->images->low_resolution->url.'">';

        endforeach;

    } while ($pictures = $instagram->pagination($pictures));

for docker-compose you can try just add

network_mode: "host"

example :

version: '2'
services:
  feedx:
    build: web
    ports:
    - "127.0.0.1:8000:8000"
    network_mode: "host"

https://docs.docker.com/compose/compose-file/#network_mode

there are packages that can simulate interfaces .

you can use es6-interface

You can use simple print statements, or any other way of writing to stdout. You can also invoke the Python debugger anywhere in your tests.

If you use nose to run your tests (which I recommend), it will collect the stdout for each test and only show it to you if the test failed, so you don't have to live with the cluttered output when the tests pass.

nose also has switches to automatically show variables mentioned in asserts, or to invoke the debugger on failed tests. For example -s (--nocapture) prevents the capture of stdout.

A Java String is an Object. (String extends Object.)

So you can get an Object reference via assignment/initialisation:

String a = "abc";
Object b = a;

I have stumbled across this question and I will submit my answer that I used and worked pretty well. I had a search box that filtered and array of objects and on my search box I used the (ngModelChange)="onChange($event)"

in my .html

<input type="text" [(ngModel)]="searchText" (ngModelChange)="reSearch(newValue)" placeholder="Search">

then in my component.ts

reSearch(newValue: string) {
    //this.searchText would equal the new value
    //handle my filtering with the new value
}

import module

Is best when you will use many functions from the module.

from module import function

Is best when you want to avoid polluting the global namespace with all the functions and types from a module when you only need function.

You could replace the original jQuery addClass and removeClass functions with your own that would call the original functions and then trigger a custom event. (Using a self-invoking anonymous function to contain the original function reference)

(function( func ) {
    $.fn.addClass = function() { // replace the existing function on $.fn
        func.apply( this, arguments ); // invoke the original function
        this.trigger('classChanged'); // trigger the custom event
        return this; // retain jQuery chainability
    }
})($.fn.addClass); // pass the original function as an argument

(function( func ) {
    $.fn.removeClass = function() {
        func.apply( this, arguments );
        this.trigger('classChanged');
        return this;
    }
})($.fn.removeClass);

Then the rest of your code would be as simple as you'd expect.

$(selector).on('classChanged', function(){ /*...*/ });

Update:

This approach does make the assumption that the classes will only be changed via the jQuery addClass and removeClass methods. If classes are modified in other ways (such as direct manipulation of the class attribute through the DOM element) use of something like MutationObservers as explained in the accepted answer here would be necessary.

Also as a couple improvements to these methods:

• Trigger an event for each class being added (classAdded) or removed (classRemoved) with the specific class passed as an argument to the callback function and only triggered if the particular class was actually added (not present previously) or removed (was present previously)

• Only trigger classChanged if any classes are actually changed

  (function( func ) {
      $.fn.addClass = function(n) { // replace the existing function on $.fn
          this.each(function(i) { // for each element in the collection
              var $this = $(this); // 'this' is DOM element in this context
              var prevClasses = this.getAttribute('class'); // note its original classes
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString(); // retain function-type argument support
              $.each(classNames.split(/\s+/), function(index, className) { // allow for multiple classes being added
                  if( !$this.hasClass(className) ) { // only when the class is not already present
                      func.call( $this, className ); // invoke the original function to add the class
                      $this.trigger('classAdded', className); // trigger a classAdded event
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged'); // trigger the classChanged event
          });
          return this; // retain jQuery chainability
      }
  })($.fn.addClass); // pass the original function as an argument
  
  (function( func ) {
      $.fn.removeClass = function(n) {
          this.each(function(i) {
              var $this = $(this);
              var prevClasses = this.getAttribute('class');
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString();
              $.each(classNames.split(/\s+/), function(index, className) {
                  if( $this.hasClass(className) ) {
                      func.call( $this, className );
                      $this.trigger('classRemoved', className);
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged');
          });
          return this;
      }
  })($.fn.removeClass);
  

With these replacement functions you can then handle any class changed via classChanged or specific classes being added or removed by checking the argument to the callback function:

$(document).on('classAdded', '#myElement', function(event, className) {
    if(className == "something") { /* do something */ }
});

#!/bin/bash
for i in $(seq 1 2 10)
do
   echo "skip by 2 value $i"
done

I had a problem where the value was not set because of a syntax error before the call.

$("#someId").value(33); //script bailed here without showing any errors Note: .value instead of .val
$("#gate").val('Gateway 2'); //this line didn't work.

Check for syntax errors before the call.

For leaving the console window open you only have to add to the last command line in the batch file:

' & pause'

Array initializer support for type inference were changed in Visual Basic 10 vs Visual Basic 9.

In previous version of VB it was required to put empty parens to signify an array. Also, it would define the array as object array unless otherwise was stated:

' Integer array
Dim i as Integer() = {1, 2, 3, 4} 

' Object array
Dim o() = {1, 2, 3}

Expanding on Chris' answer. I managed to reverse engineer the token generation process.

The token for the request is based on the text and a global TKK variable set in the page script. These are hashed in JavaScript thus resulting in the tk param.

Somewhere in the page script you will find something like this:

TKK='403413';

I managed to successfully port this to python in my fork of gTTS, so I know this works.

Edit: By now the token generation code used by gTTS has been moved into gTTS-token.

Edit 2: Google has changed the API (somewhere around 2016-05-10), this method requires some modification. I'm currently working on this. In the meantime changing the client to tw-ob seems to work.

Edit 3:

The changes are minor, yet annoying to say the least. The TKK now has two parts. Looking something like 406986.2817744745. As you can see the first part has remained the same. The second part is the sum of two seemingly random numbers. TKK=eval('((function(){var a\x3d2680116022;var b\x3d137628723;return 406986+\x27.\x27+(a+b)})())'); Here \x3d means = and \x27 is '. Both a and b change every UTC minute. At one of the final steps in the algorithm the token is XORed by the second part.

The new token generation code is:

Ar("test");

Of course I can't generate a valid url anymore, since I don't know how a and b are generated.

Got the same problem in 11 11 19, so sorry for possible necroposting. The only what helped was next solution:

var drop = $('#product_1');   // get our element, **must be unique**;
var settings = drop.attr('data-krajee-select2');  pick krajee attrs of our elem;
var drop_id = drop.attr('id');  // take id 
settings = window[settings];  // take previous settings from window;
drop.select2(settings);  // initialize select2 element with it;
$('.kv-plugin-loading').remove(); // remove loading animation;

It's, maybe, not so good, nice and precise solution, and maybe I still did not clearly understood, how it works and why, but this was the only, what keeps my select2 dropdowns, gotten by ajax, alive. Hope, this solution will be usefull or may push you in right decision in problem fixing

try this below

DateTime myDateTime = DateTime.Now;
string sqlFormattedDate = myDateTime.ToString("yyyy-MM-dd HH:mm:ss.fff");

$('#DateDepenseInput').val("2020-12-28")
the Format should be like Year-Month-Day
It worked well for me ...
