self.tableView.tableHeaderView = segmentedControl; 

If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.

Setting or Updating of Reactive Forms Form Control values can be done using both patchValue and setValue. However, it might be better to use patchValue in some instances.

patchValue does not require all controls to be specified within the parameters in order to update/set the value of your Form Controls. On the other hand, setValue requires all Form Control values to be filled in, and it will return an error if any of your controls are not specified within the parameter.

In this scenario, we will want to use patchValue, since we are only updating user and questioning:

this.qService.editQue([params["id"]]).subscribe(res => {
  this.question = res;
  this.editqueForm.patchValue({
    user: this.question.user,
    questioning: this.question.questioning
  });
});

EDIT: If you feel like doing some of ES6's Object Destructuring, you may be interested to do this instead

const { user, questioning } = this.question;

this.editqueForm.patchValue({
  user,
  questioning
});

Ta-dah!

In an instance where you want to set a placeholder and not have a default value be selected, you can use this option.

      <select defaultValue={'DEFAULT'} >
        <option value="DEFAULT" disabled>Choose a salutation ...</option>
        <option value="1">Mr</option>
        <option value="2">Mrs</option>
        <option value="3">Ms</option>
        <option value="4">Miss</option>
        <option value="5">Dr</option>
      </select>

Here the user is forced to pick an option!

EDIT

If this is a controlled component

In this case unfortunately you will have to use both defaultValue and value violating React a bit. This is because react by semantics does not allow setting a disabled value as active.

 function TheSelectComponent(props){
     let currentValue = props.curentValue || "DEFAULT";
     return(
      <select value={currentValue} defaultValue={'DEFAULT'} onChange={props.onChange}>
        <option value="DEFAULT" disabled>Choose a salutation ...</option>
        <option value="1">Mr</option>
        <option value="2">Mrs</option>
        <option value="3">Ms</option>
        <option value="4">Miss</option>
        <option value="5">Dr</option>
      </select>
    )
}

A BehaviorSubject holds one value. When it is subscribed it emits the value immediately. A Subject doesn't hold a value.

Subject example (with RxJS 5 API):

const subject = new Rx.Subject();
subject.next(1);
subject.subscribe(x => console.log(x));

Console output will be empty

BehaviorSubject example:

const subject = new Rx.BehaviorSubject(0);
subject.next(1);
subject.subscribe(x => console.log(x));

Console output: 1

In addition:

• BehaviorSubject should be created with an initial value: new Rx.BehaviorSubject(1)
• Consider ReplaySubject if you want the subject to hold more than one value

The res.header('Access-Control-Allow-Origin', '*'); wouldn't work with Autorization header. Just enable pre-flight request, using cors library:

var express = require('express')
var cors = require('cors')
var app = express()
app.use(cors())
app.options('*', cors())

You can easily define a getter for your array and clear it as follows:

  formGroup: FormGroup    
  constructor(private fb: FormBuilder) { }

  ngOnInit() {
    this.formGroup = this.fb.group({
      sliders: this.fb.array([])
    })
  }
  get sliderForms() {
    return this.formGroup.get('sliders') as FormArray
  }

  clearAll() {
    this.formGroup.reset()
    this.sliderForms.clear()
  }

This is a simple example :

List<String> citiesName = Arrays.asList( "Delhi","Mumbai","Chennai","Banglore","Kolkata");
System.out.println("Cities : "+citiesName);
List<String> sortedByName = citiesName.stream()
                .sorted((s1,s2)->s2.compareTo(s1))
                        .collect(Collectors.toList());
System.out.println("Sorted by Name : "+ sortedByName);

It may be possible that your IDE is not getting the jdk 1.8 or upper version to compile the code.

Set the Java version 1.8 for Your_Project > properties > Project Facets > Java version 1.8

In my template driven form (Angular 6) I have the following workaround:

 <div class='col-sm-2 form-group'>
            <label for='amount'>Amount</label>
            <input type='number' 
                   id='amount' 
                   name='amount' 
                   required 
                   [ngModel] = 1
                   [pattern] = "'^[1-9][0-9]*$'"
                   class='form-control' 
                   #amountInput='ngModel'/>
            <span class='text-danger' *ngIf="amountInput.touched && amountInput.invalid">
              <p *ngIf="amountInput.errors?.required">This field is <b>required</b>!</p>
              <p *ngIf="amountInput.errors?.pattern">This minimum amount is <b>1</b>!</p>
            </span>
        </div>

Alot of the above examples make use of directives and custom classes which do scale better in more complex forms, but if your looking for a simple numeric min, utilize pattern as a directive and impose a regex restriction on positive numbers only.

For those who came here looking for the answer and didnt type 3306 wrong...If like myself, you have wasted hours with no luck searching for this answer, then possibly this may help.

If you are seeing this: (HY000/2002): No connection could be made because the target machine actively refused it

Then my understanding is that it cant connect for one of the following below. Now which..

1) is your wamp, mamp, etc icon GREEN? Either way, right-click the icon --> click tools --> test both the port used for Apache (typically 80) and for Mariadb (3307?). Should say 'It is correct' for both.

2) Error comes from a .php file. So, check your dbconnect.php.

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_pw";
$dbname = "your_dbname";
$port = "3307";
?>

Is your setup correct? Does your user exist? Do they have rights? Does port match the tested port in 1)? Doesn't have to be 3307 and user can be root. You can also left click the green icon --> click MariaDB and view used port as shown in the image below. All good? Positive? ok!

3) Error comes when you login to phpmyadmin. So, check your my.ini.

Open my.ini by left clicking the green icon --> click MariaDB -->

; The following options will be passed to all MariaDB clients
[client]
;password = your_password
port = 3307
socket = /tmp/mariadb.sock

; Here follows entries for some specific programs

; The MariaDB server
[wampmariadb64]
;skip-grant-tables
port = 3307
socket = /tmp/mariadb.sock

Make sure the ports match the port MariaDB is being testing on. Then finally..

[mysqld]
port = 3307

At the bottom of my.ini, make sure this port matches as well.

4) 1-3 done? restart your WAMP and cross your fingers!

Please note that 4.0 is not sufficient since ListValuedMap, was introduced in version 4.1.

You need to use this maven repository link for version 4.1. Replicated below for convenience

I would like to add one more point to the accepted answer.

If the type of your input control is not text the pipe will not work.

Keep it in mind and save your time.

I ran a benchmarking analysis and list(mvv_count_df.select('mvv').toPandas()['mvv']) is the fastest method. I'm very surprised.

I ran the different approaches on 100 thousand / 100 million row datasets using a 5 node i3.xlarge cluster (each node has 30.5 GBs of RAM and 4 cores) with Spark 2.4.5. Data was evenly distributed on 20 snappy compressed Parquet files with a single column.

Here's the benchmarking results (runtimes in seconds):

+-------------------------------------------------------------+---------+-------------+

| list(df.select('col_name').toPandas()['col_name'])          |     0.4 | 17.5        |
| df.select('col_name').rdd.map(lambda row : row[0]).collect()|     0.9 | 69          |
| [row[0] for row in df.select('col_name').collect()]         |     1.0 | OOM         |

Golden rules to follow when collecting data on the driver node:

• Try to solve the problem with other approaches. Collecting data to the driver node is expensive, doesn't harness the power of the Spark cluster, and should be avoided whenever possible.
• Collect as few rows as possible. Aggregate, deduplicate, filter, and prune columns before collecting the data. Send as little data to the driver node as you can.

toPandas was significantly improved in Spark 2.3. It's probably not the best approach if you're using a Spark version earlier than 2.3.

See here for more details / benchmarking results.

There are two ways to go about doing this.

1. Create a state in the constructor that contains the text input. Attach an onChange event to the input box that updates state each time. Then onClick you could just alert the state object.

2. handleClick: function() { alert(this.refs.myInput.value); },

The problem is that data is captured inside the observable and I can just console log it. I want to return that value and console.log or whatever from different file by calling the function in which it resides.

Looks like you are looking for a "current value" getter inside an observable, when it emits and after an emission.

Subject and Observable doesn't have such a thing. When a value is emitted, it is passed to its subscribers and the Observable is done with it.

You may use BehaviorSubject which stores the last emitted value and emits it immediately to new subscribers.

It also has a getValue() method to get the current value;

RxJS BehaviorSubject

How to get current value of RxJS Subject or Observable?

The problem by using stream().forEach(..) with a call to add or put inside the forEach (so you mutate the external myMap or myList instance) is that you can run easily into concurrency issues if someone turns the stream in parallel and the collection you are modifying is not thread safe.

One approach you can take is to first partition the entries in the original map. Once you have that, grab the corresponding list of entries and collect them in the appropriate map and list.

Map<Boolean, List<Map.Entry<K, V>>> partitions =
    animalMap.entrySet()
             .stream()
             .collect(partitioningBy(e -> e.getValue() == null));

Map<K, V> myMap = 
    partitions.get(false)
              .stream()
              .collect(toMap(Map.Entry::getKey, Map.Entry::getValue));

List<K> myList =
    partitions.get(true)
              .stream()
              .map(Map.Entry::getKey) 
              .collect(toList());

... or if you want to do it in one pass, implement a custom collector (assuming a Tuple2<E1, E2> class exists, you can create your own), e.g:

public static <K,V> Collector<Map.Entry<K, V>, ?, Tuple2<Map<K, V>, List<K>>> customCollector() {
    return Collector.of(
            () -> new Tuple2<>(new HashMap<>(), new ArrayList<>()),
            (pair, entry) -> {
                if(entry.getValue() == null) {
                    pair._2.add(entry.getKey());
                } else {
                    pair._1.put(entry.getKey(), entry.getValue());
                }
            },
            (p1, p2) -> {
                p1._1.putAll(p2._1);
                p1._2.addAll(p2._2);
                return p1;
            });
}

with its usage:

Tuple2<Map<K, V>, List<K>> pair = 
    animalMap.entrySet().parallelStream().collect(customCollector());

You can tune it more if you want, for example by providing a predicate as parameter.

Add multiDexEnabled in gradle (app level) like this:

defaultConfig {
        ...
        ...
        multiDexEnabled true
    }

Got it. (updated/improved version)

  it('cancels changes when user presses esc', done => {
    const wrapper = mount(<EditableText defaultValue="Hello" />);
    const input = wrapper.find('input');

    input.simulate('focus');
    input.simulate('change', { target: { value: 'Changed' } });
    input.simulate('keyDown', {
      which: 27,
      target: {
        blur() {
          // Needed since <EditableText /> calls target.blur()
          input.simulate('blur');
        },
      },
    });
    expect(input.get(0).value).to.equal('Hello');

    done();
  });

You have your storyboard set up to expect an outlet called tableView but the actual outlet name is myTableView.

If you delete the connection in the storyboard and reconnect to the right variable name, it should fix the problem.

Here is the best solution for this. (ANGULAR All Version)

Addressing solution: To set a default value for @Input variable. If no value passed to that input variable then It will take the default value.

I have provided solution for this kind of similar question. You can find the full solution from here

export class CarComponent implements OnInit {
  private _defaultCar: car = {
    // default isCar is true
    isCar: true,
    // default wheels  will be 4
    wheels: 4
  };

  @Input() newCar: car = {};

  constructor() {}

  ngOnInit(): void {

   // this will concate both the objects and the object declared later (ie.. ...this.newCar )
   // will overwrite the default value. ONLY AND ONLY IF DEFAULT VALUE IS PRESENT

    this.newCar = { ...this._defaultCar, ...this.newCar };
   //  console.log(this.newCar);
  }
}

Add multiDexEnabled true in your defaultConfig in the app level gradle.

defaultConfig {
    applicationId "your application id"
    minSdkVersion 16
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner"android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}

if it is not necessary to modify the variable than a general workaround for this kind of problem would be to extract the part of code which use lambda and use final keyword on method-parameter.

import {Component} from '@angular/core';
import {NgForm} from '@angular/forms';
@Component({
    selector: 'example-app',
    template: '<form #f="ngForm" (ngSubmit)="onSubmit(f)" novalidate>
        <input name="first" ngModel required #first="ngModel">
        <input name="last" ngModel>
        <button>Submit</button>
    </form>
    <p>First name value: {{ first.value }}</p>
    <p>First name valid: {{ first.valid }}</p>
    <p>Form value: {{ f.value | json }}</p>
    <p>Form valid: {{ f.valid }}</p>',
})
export class SimpleFormComp {
    onSubmit(f: NgForm) {

        // some stuff

        f.resetForm();
    }
}

I'm doing angular 2 and typescript and I didn't realize I had a space in my arrow notation

I had .map(key = > instead of .map(key =>

Definitely keep your eyes open for stupid syntax errors

I would like to suggest to use a single RecyclerView and populate your list items dynamically. I've added a github project to describe how this can be done. You might have a look. While the other solutions will work just fine, I would like to suggest, this is a much faster and efficient way of showing multiple lists in a RecyclerView.

The idea is to add logic in your onCreateViewHolder and onBindViewHolder method so that you can inflate proper view for the exact positions in your RecyclerView.

I've added a sample project along with that wiki too. You might clone and check what it does. For convenience, I am posting the adapter that I have used.

public class DynamicListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private static final int FOOTER_VIEW = 1;
    private static final int FIRST_LIST_ITEM_VIEW = 2;
    private static final int FIRST_LIST_HEADER_VIEW = 3;
    private static final int SECOND_LIST_ITEM_VIEW = 4;
    private static final int SECOND_LIST_HEADER_VIEW = 5;

    private ArrayList<ListObject> firstList = new ArrayList<ListObject>();
    private ArrayList<ListObject> secondList = new ArrayList<ListObject>();

    public DynamicListAdapter() {
    }

    public void setFirstList(ArrayList<ListObject> firstList) {
        this.firstList = firstList;
    }

    public void setSecondList(ArrayList<ListObject> secondList) {
        this.secondList = secondList;
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        // List items of first list
        private TextView mTextDescription1;
        private TextView mListItemTitle1;

        // List items of second list
        private TextView mTextDescription2;
        private TextView mListItemTitle2;

        // Element of footer view
        private TextView footerTextView;

        public ViewHolder(final View itemView) {
            super(itemView);

            // Get the view of the elements of first list
            mTextDescription1 = (TextView) itemView.findViewById(R.id.description1);
            mListItemTitle1 = (TextView) itemView.findViewById(R.id.title1);

            // Get the view of the elements of second list
            mTextDescription2 = (TextView) itemView.findViewById(R.id.description2);
            mListItemTitle2 = (TextView) itemView.findViewById(R.id.title2);

            // Get the view of the footer elements
            footerTextView = (TextView) itemView.findViewById(R.id.footer);

            }

            final String description = secondList.get(pos).getDescription();
            final String title = secondList.get(pos).getTitle();

            mTextDescription2.setText(description);

            return 1 + secondListSize + 1;                       // second list header, second list size, footer
        else if (secondListSize == 0 && firstListSize > 0)
            return 1 + firstListSize;                            // first list header , first list size
        else return 0;
    }

    @Override
    public int getItemViewType(int position) {

        int firstListSize = 0;
        int secondListSize = 0;

        if (secondList == null && firstList == null)
            return super.getItemViewType(position);

        if (secondList != null)
            secondListSize = secondList.size();
        if (firstList != null)
            firstListSize = firstList.size();

        if (secondListSize > 0 && firstListSize > 0) {
            if (position == 0) return FIRST_LIST_HEADER_VIEW;
            else if (position == firstListSize + 1)
                return SECOND_LIST_HEADER_VIEW;
            else if (position == secondListSize + 1 + firstListSize + 1)
                return FOOTER_VIEW;
            else if (position > firstListSize + 1)
                return SECOND_LIST_ITEM_VIEW;
            else return FIRST_LIST_ITEM_VIEW;

        } else if (secondListSize > 0 && firstListSize == 0) {
            if (position == 0) return SECOND_LIST_HEADER_VIEW;
            else if (position == secondListSize + 1) return FOOTER_VIEW;
            else return SECOND_LIST_ITEM_VIEW;

        } else if (secondListSize == 0 && firstListSize > 0) {
            if (position == 0) return FIRST_LIST_HEADER_VIEW;
            else return FIRST_LIST_ITEM_VIEW;
        }

        return super.getItemViewType(position);
    }
}

There is another way of keeping your items in a single ArrayList of objects so that you can set an attribute tagging the items to indicate which item is from first list and which one belongs to second list. Then pass that ArrayList into your RecyclerView and then implement the logic inside adapter to populate them dynamically.

Hope that helps.

I think you want something along the line of:

Parent:

<Editor name={this.state.fileData} />

Editor:

var Editor = React.createClass({
  displayName: 'Editor',
  propTypes: {
    name: React.PropTypes.string.isRequired
  },
  getInitialState: function() { 
    return {
      value: this.props.name
    };
  },
  handleChange: function(event) {
    this.setState({value: event.target.value});
  },
  render: function() {
    return (
      <form id="noter-save-form" method="POST">
        <textarea id="noter-text-area" name="textarea" value={this.state.value} onChange={this.handleChange} />
        <input type="submit" value="Save" />
      </form>
    );
  }
});

This is basically a direct copy of the example provided on https://facebook.github.io/react/docs/forms.html

Update for React 16.8:

import React, { useState } from 'react';

const Editor = (props) => {
    const [value, setValue] = useState(props.name);

    const handleChange = (event) => {
        setValue(event.target.value);
    };

    return (
        <form id="noter-save-form" method="POST">
            <textarea id="noter-text-area" name="textarea" value={value} onChange={handleChange} />
            <input type="submit" value="Save" />
        </form>
    );
}

Editor.propTypes = {
    name: PropTypes.string.isRequired
};

I'm no expert with DOM or Javascript/Typescript but I think that the DOM-Tags can't handle real javascript object somehow. But putting the whole object in as a string and parsing it back to an Object/JSON worked for me:

interface TestObject {
  name:string;
  value:number;
}

@Component({
  selector: 'app',
  template: `
      <h4>Select Object via 2-way binding</h4>

      <select [ngModel]="selectedObject | json" (ngModelChange)="updateSelectedValue($event)">
        <option *ngFor="#o of objArray" [value]="o | json" >{{o.name}}</option>
      </select>

      <h4>You selected:</h4> {{selectedObject }}
  `,
  directives: [FORM_DIRECTIVES]
})
export class App {
  objArray:TestObject[];
  selectedObject:TestObject;
  constructor(){
    this.objArray = [{name: 'foo', value: 1}, {name: 'bar', value: 1}];
    this.selectedObject = this.objArray[1];
  }
  updateSelectedValue(event:string): void{
    this.selectedObject = JSON.parse(event);
  }
}

There is no need to use an ObjectIndexer<T>, or change the interface of the original object (like suggested in most of the other answers). You can simply narrow the options for key to the ones that are of type string using the following:

type KeysMatching<T, V> = { [K in keyof T]: T[K] extends V ? K : never }[keyof T];

This great solution comes from an answer to a related question here.

Like that you narrow to keys inside T that hold V values. So in your case to to limit to string you would do:

type KeysMatching<ISomeObject, string>;

In your example:

interface ISomeObject {
    firstKey:   string;
    secondKey:  string;
    thirdKey:   string;
}

let someObject: ISomeObject = {
    firstKey:   'firstValue',
    secondKey:  'secondValue',
    thirdKey:   'thirdValue'
};

let key: KeysMatching<SomeObject, string> = 'secondKey';

// secondValue narrowed to string    
let secondValue = someObject[key];

The advantage is that your ISomeObject could now even hold mixed types, and you can anyway narrow the key to string values only, keys of other value types will be considered invalid. To illustrate:

interface ISomeObject {
    firstKey:   string;
    secondKey:  string;
    thirdKey:   string;
    fourthKey:  boolean;
}

let someObject: ISomeObject = {
    firstKey:   'firstValue',
    secondKey:  'secondValue',
    thirdKey:   'thirdValue'
    fourthKey:   true
};


// Type '"fourthKey"' is not assignable to type 'KeysMatching<ISomeObject, string>'.(2322)
let otherKey: KeysMatching<SomeOtherObject, string> = 'fourthKey';

let fourthValue = someOtherObject[otherKey];

You find this example in this playground.

I did something like this :

Firebase ref = new Firebase(FIREBASE_URL);
ref.addValueEventListener(new ValueEventListener() {

@Override
public void onDataChange(DataSnapshot snapshot) {
    Map<String, Object> objectMap = (HashMap<String, Object>)    
             dataSnapshot.getValue();
    List<Match> = new ArrayList<Match>();
    for (Object obj : objectMap.values()) {
        if (obj instanceof Map) {
            Map<String, Object> mapObj = (Map<String, Object>) obj;
            Match match = new Match();
            match.setSport((String) mapObj.get(Constants.SPORT));
            match.setPlayingWith((String) mapObj.get(Constants.PLAYER));
            list.add(match);
        }
    }
  }
  @Override
  public void onCancelled(FirebaseError firebaseError) {

  }
});

First of all, the fact that the value in the database is a float does not mean that it also fits in a Java float. Float is short for floating point, and floating point types of various precisions exist. Java types float and double are both floating point types of different precision. In a database both are called FLOAT. Since double has a higher precision than float, it probably is a better idea not to cast your value to a float, because you might lose precision.

You might also use BigDecimal, which represent an arbitrary-precision number.

If you are not a big fan of XML, then just add below tag in your plist file.

In my project , I use the XMLHttpRequest to send multipart/form-data. I think it will fit you to.

and the uploader code

let xhr = new XMLHttpRequest();
xhr.open('POST', 'http://www.example.com/rest/api', true);
xhr.withCredentials = true;
xhr.send(formData);

Here is example : https://github.com/wangzilong/angular2-multipartForm

You can use the following code for your requirement

map.forEach((k,v)->System.out.println("Item : " + k + " Count : " + v));

func fucntion()
{

    var parameters = [String:String]()
    let apiToken = "Bearer \(ApiUtillity.sharedInstance.getUserData(key: "vAuthToken"))"
    let headers = ["Vauthtoken":apiToken]

    parameters = ["firstname":name,"lastname":last_name,"mobile":mobile_number,"email":emails_Address]


    Alamofire.request(ApiUtillity.sharedInstance.API(Join: "user/edit_profile"), method: .post, parameters: parameters, encoding: URLEncoding.default,headers:headers).responseJSON { response in
        debugPrint(response)
        if let json = response.result.value {
            let dict:NSDictionary = (json as? NSDictionary)!
            print(dict)
            //                print(response)

            let StatusCode = dict.value(forKey: "status") as! Int

            if StatusCode==200
            {
                ApiUtillity.sharedInstance.dismissSVProgressHUDWithSuccess(success: "Success")
                let UserData = dict.value(forKey: "data") as! NSDictionary
                print(UserData)

            }

            else if StatusCode==401
            {
                let ErrorDic:NSDictionary = dict.value(forKey: "message") as! NSDictionary
                let ErrorMessage = ErrorDic.value(forKey: "error") as! String

            }
            else
            {

                let ErrorDic:NSDictionary = dict.value(forKey: "message") as! NSDictionary
                let ErrorMessage = ErrorDic.value(forKey: "error") as! String
            }

        }
        else
        {
            ApiUtillity.sharedInstance.dismissSVProgressHUDWithError(error: "Something went wrong")
        }
    }

If you don't want to wrap it in another div as other answers have suggested, you can also wrap it in an array and it will work.

// Wrong!
return (  
   <Comp1 />
   <Comp2 />
)

It can be written as:

// Correct!
return (  
    [<Comp1 />,
    <Comp2 />]
)

Please note that the above will generate a warning: Warning: Each child in an array or iterator should have a unique "key" prop. Check the render method of 'YourComponent'.

This can be fixed by adding a key attribute to the components, if manually adding these add it like:

return (  
    [<Comp1 key="0" />,
    <Comp2 key="1" />]
)

Here is some more information on keys:Composition vs Inheritance

For example using property styles for custom container

const DriverSelector = props => {
  const Container = props.container;
  const otherProps = {
    ...( props.containerStyles && { style: props.containerStyles } )
  };

  return (
    <Container {...otherProps} >

The simplest way to get an input box is with the Read-Host cmdlet and -AsSecureString parameter.

$us = Read-Host 'Enter Your User Name:' -AsSecureString
$pw = Read-Host 'Enter Your Password:' -AsSecureString

This is especially useful if you are gathering login info like my example above. If you prefer to keep the variables obfuscated as SecureString objects you can convert the variables on the fly like this:

[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))
[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pw))

If the info does not need to be secure at all you can convert it to plain text:

$user = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))

Read-Host and -AsSecureString appear to have been included in all PowerShell versions (1-6) but I do not have PowerShell 1 or 2 to ensure the commands work identically. https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/read-host?view=powershell-3.0

You can use setState inside componentDidUpdate

The simplest approach would be to make use of the to:object within link as mentioned in documentation:
https://reactrouter.com/web/api/Link/to-object

<Link
  to={{
    pathname: "/courses",
    search: "?sort=name",
    hash: "#the-hash",
    state: { fromDashboard: true, id: 1 }
  }}
/>

We can retrieve above params (state) as below:

this.props.location.state // { fromDashboard: true ,id: 1 }

Faced to this issue after a long time since question asked here. when checking material-ui code I found it's now accessible through inputRef property.

...
<CssTextField
  inputRef={(c) => {this.myRefs.username = c}}
  label="Username"
  placeholder="xxxxxxx"
  margin="normal"
  className={classes.textField}
  variant="outlined"
  fullWidth
/>
...

Then Access value like this.

  onSaveUser = () => {
    console.log('Saving user');
    console.log(this.myRefs.username.value);
  }

The answer from ks1322 helped me to identify the issue while using docker-compose exec:

If you omit the -T flag, docker-compose exec add a special character that break output, we see b instead of 1b:

$ test=$(/usr/local/bin/docker-compose exec db bash -c "echo 1")
$ echo "${test}b"
b

echo "${test}" | cat -vte
1^M$

With -T flag, docker-compose exec works as expected:

$ test=$(/usr/local/bin/docker-compose exec -T db bash -c "echo 1")
$ echo "${test}b"
1b

It might be obvious, but make sure that you are sending to the parser URL object not a String containing www adress. This will not work:

    ObjectMapper mapper = new ObjectMapper();
    String www = "www.sample.pl";
    Weather weather = mapper.readValue(www, Weather.class);

But this will:

    ObjectMapper mapper = new ObjectMapper();
    URL www = new URL("http://www.oracle.com/");
    Weather weather = mapper.readValue(www, Weather.class);

namespace TestCSharp2
{
    **public** class Class2
    {
        int i;
        public void setValue(int i)
        {
            this.i = i;
        }
        public int getValue()
        {
        return this.i;
        }
    }
}

Add the 'Public' declaration before 'class Class2'.

I'm going to give you an example of how I read REST headers for my controllers. My controllers only accept application/json as a request type if I have data that needs to be read. I suspect that your problem is that you have an application/octet-stream that Spring doesn't know how to handle.

Normally my controllers look like this:

@Controller
public class FooController {
    @Autowired
    private DataService dataService;

    @RequestMapping(value="/foo/", method = RequestMethod.GET)
    @ResponseBody
    public ResponseEntity<Data> getData(@RequestHeader String dataId){
        return ResponseEntity.newInstance(dataService.getData(dataId);
    }

Now there is a lot of code doing stuff in the background here so I will break it down for you.

ResponseEntity is a custom object that every controller returns. It contains a static factory allowing the creation of new instances. My Data Service is a standard service class.

The magic happens behind the scenes, because you are working with JSON, you need to tell Spring to use Jackson to map HttpRequest objects so that it knows what you are dealing with.

You do this by specifying this inside your <mvc:annotation-driven> block of your config

<mvc:annotation-driven>
    <mvc:message-converters>
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper" ref="objectMapper" />
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

ObjectMapper is simply an extension of com.fasterxml.jackson.databind.ObjectMapper and is what Jackson uses to actually map your request from JSON into an object.

I suspect you are getting your exception because you haven't specified a mapper that can read an Octet-Stream into an object, or something that Spring can handle. If you are trying to do a file upload, that is something else entirely.

So my request that gets sent to my controller looks something like this simply has an extra header called dataId.

If you wanted to change that to a request parameter and use @RequestParam String dataId to read the ID out of the request your request would look similar to this:

contactId : {"fooId"} 

This request parameter can be as complex as you like. You can serialize an entire object into JSON, send it as a request parameter and Spring will serialize it (using Jackson) back into a Java Object ready for you to use.

Example In Controller:

@RequestMapping(value = "/penguin Details/", method = RequestMethod.GET)
@ResponseBody
public DataProcessingResponseDTO<Pengin> getPenguinDetailsFromList(
        @RequestParam DataProcessingRequestDTO jsonPenguinRequestDTO)

Request Sent:

jsonPengiunRequestDTO: {
    "draw": 1,
    "columns": [
        {
            "data": {
                "_": "toAddress",
                "header": "toAddress"
            },
            "name": "toAddress",
            "searchable": true,
            "orderable": true,
            "search": {
                "value": "",
                "regex": false
            }
        },
        {
            "data": {
                "_": "fromAddress",
                "header": "fromAddress"
            },
            "name": "fromAddress",
            "searchable": true,
            "orderable": true,
            "search": {
                "value": "",
                "regex": false
            }
        },
        {
            "data": {
                "_": "customerCampaignId",
                "header": "customerCampaignId"
            },
            "name": "customerCampaignId",
            "searchable": true,
            "orderable": true,
            "search": {
                "value": "",
                "regex": false
            }
        },
        {
            "data": {
                "_": "penguinId",
                "header": "penguinId"
            },
            "name": "penguinId",
            "searchable": false,
            "orderable": true,
            "search": {
                "value": "",
                "regex": false
            }
        },
        {
            "data": {
                "_": "validpenguin",
                "header": "validpenguin"
            },
            "name": "validpenguin",
            "searchable": true,
            "orderable": true,
            "search": {
                "value": "",
                "regex": false
            }
        },
        {
            "data": {
                "_": "",
                "header": ""
            },
            "name": "",
            "searchable": false,
            "orderable": false,
            "search": {
                "value": "",
                "regex": false
            }
        }
    ],
    "order": [
        {
            "column": 0,
            "dir": "asc"
        }
    ],
    "start": 0,
    "length": 10,
    "search": {
        "value": "",
        "regex": false
    },
    "objectId": "30"
}

which gets automatically serialized back into an DataProcessingRequestDTO object before being given to the controller ready for me to use.

As you can see, this is quite powerful allowing you to serialize your data from JSON to an object without having to write a single line of code. You can do this for @RequestParam and @RequestBody which allows you to access JSON inside your parameters or request body respectively.

Now that you have a concrete example to go off, you shouldn't have any problems once you change your request type to application/json.

Please make the following part of the Collectors API:

<K, V> Collector<? super Map.Entry<K, V>, ?, Map<K, V>> toMap() {
  return Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue);
}

For most use cases, it's not correct to register MultipartFilter in web.xml because Spring MVC already does the work of processing your multipart request. It's even written in the filter's javadoc.

On the server side, define a multipartResolver bean in your app context:

@Bean
public CommonsMultipartResolver multipartResolver(){
    CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
    commonsMultipartResolver.setDefaultEncoding("utf-8");
    commonsMultipartResolver.setMaxUploadSize(50000000);
    return commonsMultipartResolver;
}

On the client side, here's how to prepare the request for use with Spring RestTemplate API:

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

    LinkedMultiValueMap<String, String> pdfHeaderMap = new LinkedMultiValueMap<>();
    pdfHeaderMap.add("Content-disposition", "form-data; name=filex; filename=" + file.getOriginalFilename());
    pdfHeaderMap.add("Content-type", "application/pdf");
    HttpEntity<byte[]> doc = new HttpEntity<byte[]>(file.getBytes(), pdfHeaderMap);

    LinkedMultiValueMap<String, Object> multipartReqMap = new LinkedMultiValueMap<>();
    multipartReqMap.add("filex", doc);

    HttpEntity<LinkedMultiValueMap<String, Object>> reqEntity = new HttpEntity<>(multipartReqMap, headers);
    ResponseEntity<MyResponse> resE = restTemplate.exchange(uri, HttpMethod.POST, reqEntity, MyResponse.class);

The important thing is really to provide a Content-disposition header using the exact case, and adding name and filename specifiers, otherwise your part will be discarded by the multipart resolver.

Then, your controller method can handle the uploaded file with the following argument:

@RequestParam("filex") MultipartFile file

Hope this helps.

I think should be enough to map a boolean

In code this is:

boolean isEmpty = anyCollection.stream()
    .filter(p -> someFilter(p)) // Add my filter
    .map(p -> Boolean.TRUE) // For each element after filter, map to a TRUE
    .findAny() // Get any TRUE
    .orElse(Boolean.FALSE); // If there is no match return false

To change the color of one button like CANCEL to the red color you can use this style property called UIAlertActionStyle.destructive :

let prompt = UIAlertController.init(title: "Reset Password", message: "Enter Your E-mail :", preferredStyle: .alert)
        let okAction = UIAlertAction.init(title: "Submit", style: .default) { (action) in
              //your code
}

let cancelAction = UIAlertAction.init(title: "Cancel", style: UIAlertActionStyle.destructive) { (action) in
                //your code
        }
        prompt.addTextField(configurationHandler: nil)
        prompt.addAction(okAction)
        prompt.addAction(cancelAction)
        present(prompt, animated: true, completion: nil);

CMYR - "his could also happen if you've wired up a button to an IBAction that doesn't exist anymore (or has been renamed)"

If you're running into this problem make sure that you go to Main.storyboard, RIGHT click on the yellow box icon (view controller) at the top of the phone outline and DELETE the outlet(s) with yellow flags.

What happens in instances like this is you probably named an action, then renamed it. You need to delete the old name and if that was the only issue will start right up in sim!

As already pointed out by all the answers goto - a reserved word in Java and is not used in the language.

restart: is called an identifier followed by a colon.

Here are a few things you need to take care of if you wish to achieve similar behavior -

outer:                  // Should be placed exactly before the loop
loopingConstructOne  {  // We can have statements before the outer but not inbetween the label and the loop          
    inner:
    loopingConstructTwo {
        continue;       // This goes to the top of loopingConstructTwo and continue.
        break;          // This breaks out of loopingConstructTwo.
        continue outer; // This goes to the outer label and reenters loopingConstructOne.
        break outer;    // This breaks out of the loopingConstructOne.
        continue inner; // This will behave similar to continue.
        break inner;    // This will behave similar to break.
    }
}

I'm not sure of whether should I say similar as I already have.

Run the app using the simulator

iOS Simulator-> Hardware-> Keyboard -> iOS uses same layout as OS X

This will fix the issue if anyone out there is running their app on their device

None of them worked for and I ended up using content insets to move my view up when the keyboard appears.

Note: I was using a UITableView

Referenced solution @ keyboard-content-offset which was entirely written in objective C, the below solution is clean Swift.

Add the notification observer @ viewDidLoad()

NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(yourClass.keyboardWillBeShown), name:UIKeyboardWillShowNotification, object: nil);
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(yourClass.keyboardWillBeHidden), name:UIKeyboardWillHideNotification, object: nil);

To get the keyboard size, we first get the userInfo dictionary from the notification object, which stores any additional objects that our receiver might use.

From that dictionary we can get the CGRect object describing the keyboard’s frame by using the key UIKeyboardFrameBeginUserInfoKey.

Apply the content inset for the table view @ keyboardWillBeShown method,

func keyboardWillBeShown(sender: NSNotification)
{        
    // Move the table view

    if let keyboardSize = (sender.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.CGRectValue()
    {
        let contentInsets = UIEdgeInsetsMake(0.0, 0.0, (keyboardSize.height), 0.0);

        yourTableView.contentInset = contentInsets;

        yourTableView.scrollIndicatorInsets = contentInsets;
    }
}

Restore the view @ keyboardWillBeHidden method

func keyboardWillBeHidden(sender: NSNotification)
{
    // Moving back the table view back to the default position

    yourTableView.contentInset = UIEdgeInsetsZero;

    yourTableView.scrollIndicatorInsets = UIEdgeInsetsZero;
}

If you want to keep the device orientation also into consideration, use conditional statements to tailor the code to your needs.

// Portrait
UIEdgeInsetsMake(0.0, 0.0, (keyboardSize.height), 0.0);

// Landscape
UIEdgeInsetsMake(0.0, 0.0, (keyboardSize.width), 0.0);

LocalDateTime is a date-time without a time-zone. You specified the time zone offset format symbol in the format, however, LocalDateTime doesn't have such information. That's why the error occured.

If you want time-zone information, you should use ZonedDateTime.

DateTimeFormatter FORMATTER = DateTimeFormatter.ofPattern("yyyyMMdd HH:mm:ss.SSSSSS Z");
ZonedDateTime.now().format(FORMATTER);
=> "20140829 14:12:22.122000 +09"

For sake of simplicity, maybe you should consider using the Requests library.

An example with json response content would be something like:

import requests
r = requests.get('https://github.com/timeline.json')
r.json()

If you look for further information, in the Quickstart section, they have lots of working examples.

EDIT:

For your specific curl translation:

import requests
url = 'https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere'
payload = open("request.json")
headers = {'content-type': 'application/json', 'Accept-Charset': 'UTF-8'}
r = requests.post(url, data=payload, headers=headers)

Time Zone

To format an Instant a time-zone is required. Without a time-zone, the formatter does not know how to convert the instant to human date-time fields, and therefore throws an exception.

The time-zone can be added directly to the formatter using withZone().

DateTimeFormatter formatter =
    DateTimeFormatter.ofLocalizedDateTime( FormatStyle.SHORT )
                     .withLocale( Locale.UK )
                     .withZone( ZoneId.systemDefault() );

If you specifically want an ISO-8601 format with no explicit time-zone (as the OP asked), with the time-zone implicitly UTC, you need

DateTimeFormatter.ISO_LOCAL_DATE_TIME.withZone(ZoneId.from(ZoneOffset.UTC))

Generating String

Now use that formatter to generate the String representation of your Instant.

Instant instant = Instant.now();
String output = formatter.format( instant );

Dump to console.

System.out.println("formatter: " + formatter + " with zone: " + formatter.getZone() + " and Locale: " + formatter.getLocale() );
System.out.println("instant: " + instant );
System.out.println("output: " + output );

When run.

formatter: Localized(SHORT,SHORT) with zone: US/Pacific and Locale: en_GB
instant: 2015-06-02T21:34:33.616Z
output: 02/06/15 14:34

function myFunction() {
  var sheetname = "DateEntry";//Sheet where you want to put the date
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetname);
    // You could use now Date(); on its own but it will not look nice.
  var date = Utilities.formatDate(new Date(), "GMT+5:30", "yyyy-MM-dd");
    //var endDate = date;
    sheet.getRange(sheet.getLastRow() + 1,1).setValue(date); //Gets the last row which had value, and goes to the next empty row to put new values.
}

Testing both approaches suggested in Shail016 and bpedroso answer (https://stackoverflow.com/a/24883180/2832140), the simple StringBuilder + append(String) within a for loop, seems to execute much faster than list.stream().map([...].

Example: This code walks through a Map<Long, List<Long>> builds a json string, using list.stream().map([...]:

if (mapSize > 0) {
    StringBuilder sb = new StringBuilder("[");

    for (Map.Entry<Long, List<Long>> entry : threadsMap.entrySet()) {

        sb.append("{\"" + entry.getKey().toString() + "\":[");
        sb.append(entry.getValue().stream().map(Object::toString).collect(Collectors.joining(",")));
    }
    sb.delete(sb.length()-2, sb.length());
    sb.append("]");
    System.out.println(sb.toString());
}

On my dev VM, junit usually takes between 0.35 and 1.2 seconds to execute the test. While, using this following code, it takes between 0.15 and 0.33 seconds:

if (mapSize > 0) {
    StringBuilder sb = new StringBuilder("[");

    for (Map.Entry<Long, List<Long>> entry : threadsMap.entrySet()) {

        sb.append("{\"" + entry.getKey().toString() + "\":[");

        for (Long tid : entry.getValue()) {
            sb.append(tid.toString() + ", ");
        }
        sb.delete(sb.length()-2, sb.length());
        sb.append("]}, ");
    }
    sb.delete(sb.length()-2, sb.length());
    sb.append("]");
    System.out.println(sb.toString());
}

I had a similar problem trying to POST to MailGun for some automated emails I was implementing in an app.

I was able to get this working properly with a large HTTP response. I put the full path into Keys.plist so that I can upload my code to github and broke out some of the arguments into variables so I can have them programmatically set later down the road.

// Email the FBO with desired information
// Parse our Keys.plist so we can use our path
var keys: NSDictionary?

if let path = NSBundle.mainBundle().pathForResource("Keys", ofType: "plist") {
    keys = NSDictionary(contentsOfFile: path)
}

if let dict = keys {
    // variablize our https path with API key, recipient and message text
    let mailgunAPIPath = dict["mailgunAPIPath"] as? String
    let emailRecipient = "[email protected]"
    let emailMessage = "Testing%20email%20sender%20variables"

    // Create a session and fill it with our request
    let session = NSURLSession.sharedSession()
    let request = NSMutableURLRequest(URL: NSURL(string: mailgunAPIPath! + "from=FBOGo%20Reservation%20%3Cscheduler@<my domain>.com%3E&to=reservations@<my domain>.com&to=\(emailRecipient)&subject=A%20New%20Reservation%21&text=\(emailMessage)")!)

    // POST and report back with any errors and response codes
    request.HTTPMethod = "POST"
    let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
        if let error = error {
            print(error)
        }

        if let response = response {
            print("url = \(response.URL!)")
            print("response = \(response)")
            let httpResponse = response as! NSHTTPURLResponse
            print("response code = \(httpResponse.statusCode)")
        }
    })
    task.resume()
}

The Mailgun Path is in Keys.plist as a string called mailgunAPIPath with the value:

https://API:key-<my key>@api.mailgun.net/v3/<my domain>.com/messages?

Hope this helps offers a solution to someone trying to avoid using 3rd party code for their POST requests!

I wrote an extension for that purpose. It always returns an Int. If the string does not fit into an Int, 0 is returned.

extension String {
    func toTypeSafeInt() -> Int {
        if let safeInt = self.toInt() {
            return safeInt
        } else {
            return 0
        }
    }
}

I'm going to try a simpler answer:

Explanation of the problem

First, let's understand the flow of events when a page is served from our server:

• First PHP is run, it generates the HTML that is served to the client.
• Then, the HTML is delivered to the client, after PHP is done with it, I'd like to emphasize that once the code leaves the server - PHP is done with it and can no longer access it.
• Then, the HTML with JavaScript reaches the client, which can execute JavaScript on that HTML.

So really, the core thing to remember here is that HTTP is stateless. Once a request left the server, the server can not touch it. So, that leaves our options to:

1. Send more requests from the client after the initial request is done.
2. Encode what the server had to say in the initial request.

Solutions

That's the core question you should be asking yourself is:

Am I writing a website or an application?

Websites are mainly page based, and the page load times needs to be as fast as possible (for example - Wikipedia). Web applications are more AJAX heavy and perform a lot of round trips to get the client fast information (for example - a stock dashboard).

Website

Sending more requests from the client after the initial request is done is slow as it requires more HTTP requests which have significant overhead. Moreover, it requires asynchronousity as making an AJAX request requires a handler for when it's complete.

I would not recommend making another request unless your site is an application for getting that information from the server.

You want fast response times which have a huge impact on conversion and load times. Making Ajax requests is slow for the initial uptime in this case and unneeded.

You have two ways to tackle the issue

• Set a cookie - cookies are headers sent in HTTP requests that both the server and client can read.
• Encode the variable as JSON - JSON looks very close to JavaScript objects and most JSON objects are valid JavaScript variables.

Setting a cookie is really not very difficult, you just assign it a value:

setcookie("MyCookie", $value); // Sets the cookie to the value, remember, do not
                               // Set it with HTTP only to true.

Then, you can read it with JavaScript using document.cookie:

Here is a short hand rolled parser, but the answer I linked to right above this has better tested ones:

var cookies = document.cookie.split(";").
    map(function(el){ return el.split("="); }).
    reduce(function(prev,cur){ prev[cur[0]] = cur[1];return prev },{});

cookies["MyCookie"] // Value set with PHP.

Cookies are good for a little data. This is what tracking services often do.

Once we have more data, we can encode it with JSON inside a JavaScript variable instead:

<script>
    var myServerData = <?=json_encode($value)?>; // Don't forget to sanitize
                                                 //server data
</script>

Assuming $value is json_encodeable on the PHP side (it usually is). This technique is what Stack Overflow does with its chat for example (only using .NET instead of PHP).

Application

If you're writing an application - suddenly the initial load time isn't always as important as the ongoing performance of the application, and it starts to pay off to load data and code separately.

My answer here explains how to load data using AJAX in JavaScript:

function callback(data){
    // What do I do with the response?
}

var httpRequest = new XMLHttpRequest;
httpRequest.onreadystatechange = function(){
    if (httpRequest.readyState === 4) { // Request is done
        if (httpRequest.status === 200) { // successfully
            callback(httpRequest.responseText); // We're calling our method
        }
    }
};
httpRequest.open('GET', "/echo/json");
httpRequest.send();

Or with jQuery:

$.get("/your/url").done(function(data){
    // What do I do with the data?
});

Now, the server just needs to contain a /your/url route/file that contains code that grabs the data and does something with it, in your case:

<$php
     ...
     $val = myService->getValue(); // Makes an API and database call
     echo json_encode($val); // Write it to the output
 $>

This way, our JavaScript file asks for the data and shows it rather than asking for code or for layout. This is cleaner and starts to pay off as the application gets higher. It's also better separation of concerns and it allows testing the client side code without any server side technology involved which is another plus.

Postscript: You have to be very aware of XSS attack vectors when you inject anything from PHP to JavaScript. It's very hard to escape values properly and it's context sensitive. If you're unsure how to deal with XSS, or unaware of it - please read this OWASP article, this one and this question.

If nothing happens even if you added all the annotation needed, try to add this dependency to your pom.xml, I just faced the same problem and resolved it by adding this one here:

<dependency>
   <groupId>commons-configuration</groupId>
   <artifactId>commons-configuration</artifactId>
   <version>1.9</version>
</dependency>

It's an interesting question, because it shows that there are a lot of different approaches to achieve the same result. Below I show three different implementations.

Default methods in Collection Framework: Java 8 added some methods to the collections classes, that are not directly related to the Stream API. Using these methods, you can significantly simplify the implementation of the non-stream implementation:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    Map<String, DataSet> result = new HashMap<>();
    multiDataPoints.forEach(pt ->
        pt.keyToData.forEach((key, value) ->
            result.computeIfAbsent(
                key, k -> new DataSet(k, new ArrayList<>()))
            .dataPoints.add(new DataPoint(pt.timestamp, value))));
    return result.values();
}

Stream API with flatten and intermediate data structure: The following implementation is almost identical to the solution provided by Stuart Marks. In contrast to his solution, the following implementation uses an anonymous inner class as intermediate data structure.

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.keyToData.entrySet().stream().map(e ->
            new Object() {
                String key = e.getKey();
                DataPoint dataPoint = new DataPoint(mdp.timestamp, e.getValue());
            }))
        .collect(
            collectingAndThen(
                groupingBy(t -> t.key, mapping(t -> t.dataPoint, toList())),
                m -> m.entrySet().stream().map(e -> new DataSet(e.getKey(), e.getValue())).collect(toList())));
}

Stream API with map merging: Instead of flattening the original data structures, you can also create a Map for each MultiDataPoint, and then merge all maps into a single map with a reduce operation. The code is a bit simpler than the above solution:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .map(mdp -> mdp.keyToData.entrySet().stream()
            .collect(toMap(e -> e.getKey(), e -> asList(new DataPoint(mdp.timestamp, e.getValue())))))
        .reduce(new HashMap<>(), mapMerger())
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

You can find an implementation of the map merger within the Collectors class. Unfortunately, it is a bit tricky to access it from the outside. Following is an alternative implementation of the map merger:

<K, V> BinaryOperator<Map<K, List<V>>> mapMerger() {
    return (lhs, rhs) -> {
        Map<K, List<V>> result = new HashMap<>();
        lhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        rhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        return result;
    };
}

(this question is a duplicate of In chart.js, Is it possible to hide x-axis label/text of bar chart if accessing from mobile?) They added the option, 2.1.4 (and maybe a little earlier) has it

var myLineChart = new Chart(ctx, {
    type: 'line',
    data: data,
    options: {
        scales: {
            xAxes: [{
                ticks: {
                    display: false
                }
            }]
        }
    }
}

I am answering this because it's the top result in Google for "String isBlank() Method".

If you are using Java 11 or above, you can use the String class isBlank() method. This method does the same thing as Apache Commons StringUtils class.

I have written a small post on this method examples, read it here.

The best way to do this would be to use the promise returning function as it is, like this

lookupValue(file).then(function(res) {
    // Write the code which depends on the `res.val`, here
});

The function which invokes an asynchronous function cannot wait till the async function returns a value. Because, it just invokes the async function and executes the rest of the code in it. So, when an async function returns a value, it will not be received by the same function which invoked it.

So, the general idea is to write the code which depends on the return value of an async function, in the async function itself.

try {
        ScriptEngineManager manager = new ScriptEngineManager();
        ScriptEngine engine = manager.getEngineByName("JavaScript");
        System.out.println("okay1");
        FileInputStream fileInputStream = new FileInputStream("C:/Users/Kushan/eclipse-workspace/sureson.lk/src/main/webapp/js/back_end_response.js");
        System.out.println("okay2");
        if (fileInputStream != null){
         BufferedReader reader = new BufferedReader(new InputStreamReader(fileInputStream));
         engine.eval(reader);
         System.out.println("okay3");
        // Invocable javascriptEngine = null;
         System.out.println("okay4");
        Invocable invocableEngine = (Invocable)engine;
         System.out.println("okay5");
         int x=0;
         System.out.println("invocableEngine is : "+invocableEngine);
         Object object = invocableEngine.invokeFunction("backend_message",x);

         System.out.println("okay6");
        }
        }catch(Exception e) {
            System.out.println("erroe when calling js function"+ e);
        }

Map<String, Integer> map = new HashMap<>();
map.put("test1", 1);
map.put("test2", 2);

Map<String, Integer> map2 = new HashMap<>();
map.forEach(map2::put);

System.out.println("map: " + map);
System.out.println("map2: " + map2);
// Output:
// map:  {test2=2, test1=1}
// map2: {test2=2, test1=1}

You can use the forEach method to do what you want.

What you're doing there is:

map.forEach(new BiConsumer<String, Integer>() {
    @Override
    public void accept(String s, Integer integer) {
        map2.put(s, integer);     
    }
});

Which we can simplify into a lambda:

map.forEach((s, integer) ->  map2.put(s, integer));

And because we're just calling an existing method we can use a method reference, which gives us:

map.forEach(map2::put);

I tested your code and works properly. I've added a small demo with another way to print all the data in the map:

ConcurrentHashMap<String, Integer> map = new ConcurrentHashMap<String, Integer>();
map.put("A", 1);
map.put("B", 2);
map.put("C", 3);

for (String key : map.keySet()) {
    System.out.println(key + " " + map.get(key));
}

for (Map.Entry<String, Integer> entry : map.entrySet()) {
    String key = entry.getKey().toString();
    Integer value = entry.getValue();
    System.out.println("key, " + key + " value " + value);
}

I had a similar problem. My data is provided by a remote server. I want some value to be entered in the selectize box, but it is not sure in advance whether this value is a valid one on the server.

So I want the value to be entered in the box, and I want selectize to show the possible options just if like the user had entered the value.

I ended up using this hack (which it is probably unsupported):

var $selectize = $("#my_input").selectize(/* settings with load*/);
var selectize = $select[0].selectize;
// get the search from the remote server
selectize.onSearchChange('my value');
// enter the input in the input field
$selectize.parent().find('input').val('my value');
// focus on the input field, to make the options visible
$selectize.parent().find('input').focus();

You can/should set your parameter to value to DBNull.Value;

if (variable == "")
{
     cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = DBNull.Value;
}
else
{
     cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = variable;
}

Or you can leave your server side set to null and not pass the param at all.

Another way using a the TryGetValues method.

public string Postsam([FromBody]object jsonData)
{
    IEnumerable<string> headerValues;

    if (Request.Headers.TryGetValues("Custom", out headerValues))
    {
        string token = headerValues.First();
    }
}   

Let's evaluate the parsing of each:

http://jsfiddle.net/brandonscript/Y2dGv/

var json1 = '{}';
var json2 = '{"myCount": null}';
var json3 = '{"myCount": 0}';
var json4 = '{"myString": ""}';
var json5 = '{"myString": "null"}';
var json6 = '{"myArray": []}';

console.log(JSON.parse(json1)); // {}
console.log(JSON.parse(json2)); // {myCount: null}
console.log(JSON.parse(json3)); // {myCount: 0}
console.log(JSON.parse(json4)); // {myString: ""}
console.log(JSON.parse(json5)); // {myString: "null"}
console.log(JSON.parse(json6)); // {myArray: []}

The tl;dr here:

The fragment in the json2 variable is the way the JSON spec indicates null should be represented. But as always, it depends on what you're doing -- sometimes the "right" way to do it doesn't always work for your situation. Use your judgement and make an informed decision.

JSON1 {}

This returns an empty object. There is no data there, and it's only going to tell you that whatever key you're looking for (be it myCount or something else) is of type undefined.

JSON2 {"myCount": null}

In this case, myCount is actually defined, albeit its value is null. This is not the same as both "not undefined and not null", and if you were testing for one condition or the other, this might succeed whereas JSON1 would fail.

This is the definitive way to represent null per the JSON spec.

JSON3 {"myCount": 0}

In this case, myCount is 0. That's not the same as null, and it's not the same as false. If your conditional statement evaluates myCount > 0, then this might be worthwhile to have. Moreover, if you're running calculations based on the value here, 0 could be useful. If you're trying to test for null however, this is actually not going to work at all.

JSON4 {"myString": ""}

In this case, you're getting an empty string. Again, as with JSON2, it's defined, but it's empty. You could test for if (obj.myString == "") but you could not test for null or undefined.

JSON5 {"myString": "null"}

This is probably going to get you in trouble, because you're setting the string value to null; in this case, obj.myString == "null" however it is not == null.

JSON6 {"myArray": []}

This will tell you that your array myArray exists, but it's empty. This is useful if you're trying to perform a count or evaluation on myArray. For instance, say you wanted to evaluate the number of photos a user posted - you could do myArray.length and it would return 0: defined, but no photos posted.

While the accepted answer isn't technically wrong, it doesn't answer the original question nor the follow up question in the comments, which was what I came here looking for. But I figured it out, so here goes.

If you want to find all Posts that have Users (and only the ones that have users) where the SQL would look like this:

SELECT * FROM posts INNER JOIN users ON posts.user_id = users.id

Which is semantically the same thing as the OP's original SQL:

SELECT * FROM posts, users WHERE posts.user_id = users.id

then this is what you want:

Posts.findAll({
  include: [{
    model: User,
    required: true
   }]
}).then(posts => {
  /* ... */
});

Setting required to true is the key to producing an inner join. If you want a left outer join (where you get all Posts, regardless of whether there's a user linked) then change required to false, or leave it off since that's the default:

Posts.findAll({
  include: [{
    model: User,
//  required: false
   }]
}).then(posts => {
  /* ... */
});

If you want to find all Posts belonging to users whose birth year is in 1984, you'd want:

Posts.findAll({
  include: [{
    model: User,
    where: {year_birth: 1984}
   }]
}).then(posts => {
  /* ... */
});

Note that required is true by default as soon as you add a where clause in.

If you want all Posts, regardless of whether there's a user attached but if there is a user then only the ones born in 1984, then add the required field back in:

Posts.findAll({
  include: [{
    model: User,
    where: {year_birth: 1984}
    required: false,
   }]
}).then(posts => {
  /* ... */
});

If you want all Posts where the name is "Sunshine" and only if it belongs to a user that was born in 1984, you'd do this:

Posts.findAll({
  where: {name: "Sunshine"},
  include: [{
    model: User,
    where: {year_birth: 1984}
   }]
}).then(posts => {
  /* ... */
});

If you want all Posts where the name is "Sunshine" and only if it belongs to a user that was born in the same year that matches the post_year attribute on the post, you'd do this:

Posts.findAll({
  where: {name: "Sunshine"},
  include: [{
    model: User,
    where: ["year_birth = post_year"]
   }]
}).then(posts => {
  /* ... */
});

I know, it doesn't make sense that somebody would make a post the year they were born, but it's just an example - go with it. :)

I figured this out (mostly) from this doc:

• http://docs.sequelizejs.com/en/latest/docs/models-usage/#eager-loading

1. You can just use localStorage and remember the date it was first created in session cookie. When localStorage "session" is older than the value of cookie then you may clear the localStorage

   Cons of this is that someone can still read the data after the browser is closed so it's not a good solution if your data is private and confidental.

2. You can store your data to localStorage for a couple of seconds and add event listener for a storage event. This way you will know when any of the tabs wrote something to the localStorage and you can copy its content to the sessionStorage, then just clear the localStorage

As Ajay beniwal mentioned above you need to use Apply to start digestion.

var app = angular.module('test', []);

app.controller('TestCtrl', function ($scope) {
   $scope.testValue = 0;

    setInterval(function() {
        console.log($scope.testValue++);
        $scope.$apply() 
    }, 500);
});

If you are using Java 7+, you may want to use NIO.2, e.g.:

❍ Code:

public static void main(String[] args) throws Exception {

    File file = new File("test.csv");

    List<String> lines = Files.readAllLines(file.toPath(), 
            StandardCharsets.UTF_8);

    for (String line : lines) {
        String[] array = line.split(",", -1);
        System.out.println(array[0]);
    }

}

❍ Output:

a
1RW
1RW
1RW
1RW
1RW
1RW
1R1W
1R1W
1R1W

This error may happen when mapping variables you defined in REST definition do not match with @PathVariable names.

Example: Suppose you defined in the REST definition

@GetMapping(value = "/{appId}", produces = "application/json", consumes = "application/json")

Then during the definition of the function, it should be

public ResponseEntity<List> getData(@PathVariable String appId)

This error may occur when you use any other variable other than defined in the REST controller definition with @PathVariable. Like, the below code will raise the error as ID is different than appId variable name:

public ResponseEntity<List> getData(@PathVariable String ID)

It's simple! Just annotate with required.

[Required]
public bool MyField { get; set; }

the resultant migration will be:

migrationBuilder.AddColumn<bool>(
name: "MyField",
table: "MyTable",
nullable: false,
defaultValue: false);

If you want true, change the defaultValue to true in the migration before updating the database

You're mapping this JSON

{
    "id": 2,
    "socket": "0c317829-69bf-43d6-b598-7c0c550635bb",
    "type": "getDashboard",
    "data": {
        "workstationUuid": "ddec1caa-a97f-4922-833f-632da07ffc11"
    },
    "reply": true
}

that contains an element named data that has a JSON object as its value. You are trying to deserialize the element named workstationUuid from that JSON object into this setter.

@JsonProperty("workstationUuid")
public void setWorkstation(String workstationUUID) {

This won't work directly because Jackson sees a JSON_OBJECT, not a String.

Try creating a class Data

public class Data { // the name doesn't matter 
    @JsonProperty("workstationUuid")
    private String workstationUuid;
    // getter and setter
}

the switch up your method

@JsonProperty("data")
public void setWorkstation(Data data) {
    // use getter to retrieve it

In Tomcat a .java and .class file will be created for every jsp files with in the application and the same can be found from the path below, Apache-Tomcat\work\Catalina\localhost\'ApplicationName'\org\apache\jsp\index_jsp.java

In your case the jsp name is error.jsp so the path should be something like below Apache-Tomcat\work\Catalina\localhost\'ApplicationName'\org\apache\jsp\error_jsp.java in line no 124 you are trying to access a null object which results in null pointer exception.

The query can be written slightly simpler, like this:

DECLARE @T INT = 2 

SELECT CASE 
         WHEN @T < 1 THEN 'less than one' 
         WHEN @T = 1 THEN 'one' 
         ELSE 'greater than one' 
       END T

As you see in an error UseCalls.java:27: error: cannot find symbol return String.parseString(input); there is no method parseString in String class. There is no need to parse it as long as JOptionPane.showInputDialog(prompt); already returns a string.

i. Please check the InnerException property of the TypeInitializationException

ii. Also, this may occur due to mismatch between the runtime versions of the assemblies. Please verify the runtime versions of the main assembly (calling application) and the referred assembly

For me, the problem was I was using a package that isn't included in package.json nor installed.

import { ToastrService } from 'ngx-toastr';

So when the compiler tried to compile this, it threw an error.

(I installed it locally, and when running a build on an external server the error was thrown)

Make the member private and add a setter/getter pair. In your setter, if null, then set default value instead. Additionally, I have shown the snippet with the getter also returning a default when internal value is null.

class JavaObject {
    private static final String DEFAULT="Default Value";

    public JavaObject() {
    }

    @NotNull
    private String notNullMember;
    public void setNotNullMember(String value){
            if (value==null) { notNullMember=DEFAULT; return; }
            notNullMember=value;
            return;
    }

    public String getNotNullMember(){
            if (notNullMember==null) { return DEFAULT;}
            return notNullMember;
    }

    public String optionalMember;
}

I`ve added

initSelection: function (element, callback) {

      callback({ id: 1, text: 'Text' });
}

BUT also

.select2('val', []);

at the end.

This solved my issue.

First off, RangeToHTML. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b?u?t?c?h?e?r?e?d? modified.

On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.

For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

Try this

function readRows() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var rows = sheet.getDataRange();
  var numRows = rows.getNumRows();
  //var values = rows.getValues();

  var Names = sheet.getRange("A2:A7");
  var Name = [
    Names.getCell(1, 1).getValue(),
    Names.getCell(2, 1).getValue(),
    .....
    Names.getCell(5, 1).getValue()]

You can define arrays simply as follows, instead of allocating and then assigning.

var arr = [1,2,3,5]

Your initial error was because of the following line, and ones like it

var Name[0] = Name_cell.getValue(); 

Since Name is already defined and you are assigning the values to its elements, you should skip the var, so just

Name[0] = Name_cell.getValue();

Pro tip: For most issues that, like this one, don't directly involve Google services, you are better off Googling for the way to do it in javascript in general.

There isn't a way to iterate over a Stream whilst having access to the index because a Stream is unlike any Collection. A Stream is merely a pipeline for carrying data from one place to another, as stated in the documentation:

No storage. A stream is not a data structure that stores elements; instead, they carry values from a source (which could be a data structure, a generator, an IO channel, etc) through a pipeline of computational operations.

Of course, as you appear to be hinting at in your question, you could always convert your Stream<V> to a Collection<V>, such as a List<V>, in which you will have access to the indexes.

This should fix the error

You need to first add using Microsoft.Win32; to your code page.

Then you can begin to use the Registry classes:

try
{
    using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\\Wow6432Node\\MySQL AB\\MySQL Connector\\Net"))
    {
        if (key != null)
        {
            Object o = key.GetValue("Version");
            if (o != null)
            {
                Version version = new Version(o as String);  //"as" because it's REG_SZ...otherwise ToString() might be safe(r)
                //do what you like with version
            }
        }
    }
}
catch (Exception ex)  //just for demonstration...it's always best to handle specific exceptions
{
    //react appropriately
}

BEWARE: unless you have administrator access, you are unlikely to be able to do much in LOCAL_MACHINE. Sometimes even reading values can be a suspect operation without admin rights.

The error says that a warning was treated as an error, therefore your problem is a warning message! The object file is then not created because there was an error. So you need to check your warnings and fix them.

In case you don't know how to find them: Open the Error List (View > Error List) and click on Warning.

I know this is late but I thought it'd be helpful to someone who'll come searching for an answer to this. You can use a Bundle to return multiple datatype values without creating another method. I tried it and worked perfectly.

In Your MainActivity where you call the method:

Bundle myBundle = method();
String myString = myBundle.getString("myS");
String myInt = myBundle.getInt("myI");

Method:

public Bundle method() {
    mBundle = new Bundle();
    String typicalString = "This is String";
    Int typicalInt = 1;
    mBundle.putString("myS", typicalString);
    mBundle.putInt("myI", typicalInt);
    return mBundle;
}

P.S: I'm not sure if it's OK to implement a Bundle like this, but for me, it worked out perfectly.

Make sure that the column values u added in entity class having get set properties also in the same order which is present in target table.

SInce you don't have white-space and underscore in your character class I think following regex will be better for you:

Pattern regex = Pattern.compile("[^\w\s]");

Which means match everything other than [A-Za-z0-9\s_]

Unicode version:

Pattern regex = Pattern.compile("[^\p{L}\d\s_]");

int color = (A & 0xff) << 24 | (R & 0xff) << 16 | (G & 0xff) << 8 | (B & 0xff);

Try this Javascript (jquery) code. Its an ajax request to an external URL. Use the callback function to fire any code:

<script type="text/javascript">
$(function() {
  $('form').submit(function(){
    $.post('http://example.com/upload', function() {
      window.location = 'http://google.com';
    });
    return false;
  });
});
</script>

Use default method name() as given bellows

public enum Category {
        ONE("one"),
        TWO ("two"),
        THREE("three");

        private final String name;

        Category(String s) {
            name = s;
        }

    }

public class Main {
    public static void main(String[] args) throws Exception {
        System.out.println(Category.ONE.name());
    }
}

Modify your query to generate the output that you want.

Try casting them to int:

select cast(bitFlag as int)

Or, if you like, use case:

select (case when bitFlag = 0 then 0 else 1 end)

Either remove the below code from the pom.xml or correct your java version to make it work.

  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.0</version>
    <configuration>

Value is not null, but DBNull.Value.

object value = cmd.ExecuteScalar();
if(value == DBNull.Value)

This is the JSON String we want to decode :

{ 
   "stats": { 
       "sdr": "aa:bb:cc:dd:ee:ff", 
       "rcv": "aa:bb:cc:dd:ee:ff", 
       "time": "UTC in millis", 
       "type": 1, 
       "subt": 1, 
       "argv": [
          {"1": 2}, 
          {"2": 3}
       ]}
}

I store this string under the variable name "sJSON" Now, this is how to decode it :)

// Creating a JSONObject from a String 
JSONObject nodeRoot  = new JSONObject(sJSON); 

// Creating a sub-JSONObject from another JSONObject
JSONObject nodeStats = nodeRoot.getJSONObject("stats");

// Getting the value of a attribute in a JSONObject
String sSDR = nodeStats.getString("sdr");

Be sure to remember to invoke json.loads() on the contents of the file, as opposed to the file path of that JSON:

json_file_path = "/path/to/example.json"

with open(json_file_path, 'r') as j:
     contents = json.loads(j.read())

I think a lot of people are guilty of doing this every once in a while (myself included):

contents = json.loads(json_file_path)

Sum the object key value by parse Integer. Converting string format to integer and summing the values

var obj = {
  pay: 22
};
obj.pay;
console.log(obj.pay);
var x = parseInt(obj.pay);
console.log(x + 20);

You also can use this:

var firstOrDefault = lstComp.FirstOrDefault();
if(firstOrDefault != null) 
{
    //doSmth
}

But from what I see you have quite a simple error in syntax

<p th:text="${bean.field} + '!' + ${bean.field}">Static content</p>

the correct syntax would look like

<p th:text="${bean.field + '!' + bean.field}">Static content</p>

As a matter of fact, the syntax th:text="'static part' + ${bean.field}" is equal to th:text="${'static part' + bean.field}".

Try it out. Even though this is probably kind of useless now after 6 months.

Please note that if you have multiple application.properties files throughout your codebase, then try adding your value to the parent project's property file.

You can check your project's pom.xml file to identify what the parent project of your current project is.

Alternatively, try using environment.getProperty() instead of @Value.

Heres the method I used in my logging library: https://github.com/goktugyil/QorumLogs

This method fills html forms inside Google Forms. Hope it helps someone using Swift.

var url = NSURL(string: urlstring)

var request = NSMutableURLRequest(URL: url!)
request.HTTPMethod = "POST"
request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.HTTPBody = postData.dataUsingEncoding(NSUTF8StringEncoding)
var connection = NSURLConnection(request: request, delegate: nil, startImmediately: true)

First of all, you don't quite get what's reduce's previous value is.

In you pseudo code you have return previous.value + current.value, therefore the previous value will be a number on the next call, not an object.

Second, reduce is an Array method, not an Object's one, and you can't rely on the order when you're iterating the properties of an object (see: https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Statements/for...in, this is applied to Object.keys too); so I'm not sure if applying reduce over an object makes sense.

However, if the order is not important, you can have:

Object.keys(obj).reduce(function(sum, key) {
    return sum + obj[key].value;
}, 0);

Or you can just map the object's value:

Object.keys(obj).map(function(key) { return this[key].value }, obj).reduce(function (previous, current) {
    return previous + current;
});

P.S. in ES6 with the fat arrow function's syntax (already in Firefox Nightly), you could shrink a bit:

Object.keys(obj).map(key => obj[key].value).reduce((previous, current) => previous + current);

You need to add a Serializable attribute to the class which you want to serialize.

[Serializable]
public class OrgPermission

Can we see your import block? because it seems that you have imported the wrong Iterator class.

The one you should use is java.util.Iterator

To make sure, try:

java.util.Iterator iter = hm.keySet().iterator();

I personally suggest the following:

Map Declaration using Generics and declaration using the Interface Map<K,V> and instance creation using the desired implementation HashMap<K,V>

Map<Integer, String> hm = new HashMap<>();

and for the loop:

for (Integer key : hm.keySet()) {
    System.out.println("Key = " + key + " - " + hm.get(key));
}

UPDATE 3/5/2015

Found out that iterating over the Entry set will be better performance wise:

for (Map.Entry<Integer, String> entry : hm.entrySet()) {
    Integer key = entry.getKey();
    String value = entry.getValue();

}

UPDATE 10/3/2017

For Java8 and streams, your solution will be (Thanks @Shihe Zhang)

 hm.forEach((key, value) -> System.out.println(key + ": " + value))

You need to add a name attribute to your dropdown list, then you need to add a required attribute, and then you can reference the error using myForm.[input name].$error.required:

HTML:

        <form name="myForm" ng-controller="Ctrl" ng-submit="save(myForm)" novalidate>
        <input type="text" name="txtServiceName" ng-model="ServiceName" required>
<span ng-show="myForm.txtServiceName.$error.required">Enter Service Name</span>
<br/>
          <select name="service_id" class="Sitedropdown" style="width: 220px;"          
                  ng-model="ServiceID" 
                  ng-options="service.ServiceID as service.ServiceName for service in services"
                  required> 
            <option value="">Select Service</option> 
          </select> 
          <span ng-show="myForm.service_id.$error.required">Select service</span>

        </form>

    Controller:

        function Ctrl($scope) {
          $scope.services = [
            {ServiceID: 1, ServiceName: 'Service1'},
            {ServiceID: 2, ServiceName: 'Service2'},
            {ServiceID: 3, ServiceName: 'Service3'}
          ];

    $scope.save = function(myForm) {
    console.log('Selected Value: '+ myForm.service_id.$modelValue);
    alert('Data Saved! without validate');
    };
        }

Here's a working plunker.

You are looking for:

db.Users.Attach(updatedUser);
var entry = db.Entry(updatedUser);
entry.Property(e => e.Email).IsModified = true;
// other changed properties
db.SaveChanges();

To answer your question, firstly I would strongly recommend looking at the Documentation.

Without overriding the equals() method, it will act like "==". When you use the "==" operator on objects, it simply checks to see if those pointers refer to the same object. Not if their members contain the same value.

We override to keep our code clean, and abstract the comparison logic from the If statement, into the object. This is considered good practice and takes advantage of Java's heavily Object Oriented Approach.

Partial mocking of a class is also supported via Spy in mockito

List list = new LinkedList();
List spy = spy(list);

//optionally, you can stub out some methods:
when(spy.size()).thenReturn(100);

//using the spy calls real methods
spy.add("one");
spy.add("two");

//size() method was stubbed - 100 is printed
System.out.println(spy.size());

Check the 1.10.19 and 2.7.22 docs for detailed explanation.

The previous functions didn't work for me, so I've made another function that use the same logic of one of the answers above: parse the formula in the cell to find the referenced range of cells to examine and than look for the coloured cells. You can find a detailed description here: Google Script count coloured with reference, but the code is below:

function countColoured(reference) {
  var sheet = SpreadsheetApp.getActiveSheet();
  var formula = SpreadsheetApp.getActiveRange().getFormula();
  var args = formula.match(/=\w+\((.*)\)/i)[1].split('!');
  try {
    if (args.length == 1) {
      var range = sheet.getRange(args[0]);
    }
    else {
      sheet = ss.getSheetByName(args[0].replace(/'/g, ''));
      range = sheet.getRange(args[1]);
    }
  }
  catch(e) {
    throw new Error(args.join('!') + ' is not a valid range');
  }
  var c = 0;
  var numRows = range.getNumRows();
  var numCols = range.getNumColumns();
  for (var i = 1; i <= numRows; i++) {
    for (var j = 1; j <= numCols; j++) {
      c = c + ( range.getCell(i,j).getBackground() == "#ffffff" ? 0 : 1 );
    }
  }
  return c > 0 ? c : "" ;
}

For simplicity and well structured sake, use SpringMVC. It's just so simple.

@RequestMapping("/carlist.json")
public @ResponseBody List<String> getCarList() {
    return carService.getAllCars();
}

Late to the party, but the top voted answers all seemed like hacks to me.

All I did was remove the following from my app.config in the test project. Worked.

  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="mssqllocaldb" />
      </parameters>
    </defaultConnectionFactory>
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>

I ran into a similar error when creating a custom view class, that was because somehow one of the outlet got hooked up twice in the XIB file(I think I initially control dragged the control directly to the code, but latter control dragged again from the File's owner). I opened the XIB file and remove one of them, after that everything worked fine. Hopefully this helps.

This could happen if you are using reflection to GetProperty of an object which is null.

I post my solution in Kotlin, but it can work with java objects as well. I create a function extension so any object can use this function.

fun Any.iterateOverComponents() {

val fields = this.javaClass.declaredFields

fields.forEachIndexed { i, field ->

    fields[i].isAccessible = true
    // get value of the fields
    val value = fields[i].get(this)

    // print result
    Log.w("Msg", "Value of Field "
            + fields[i].name
            + " is " + value)
}}

Take a look at this webpage: https://www.geeksforgeeks.org/field-get-method-in-java-with-examples/

There is much simpler way:

using System;
using System.Collections.Generic;
....
var caseInsensitiveDictionary = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);

In Stored procedure, you return the values using OUT parameter ONLY. As you have defined two variables in your example:

   outstaticip OUT VARCHAR2, outcount OUT NUMBER

Just assign the return values to the out parameters i.e. outstaticip and outcount and access them back from calling location. What I mean here is: when you call the stored procedure, you will be passing those two variables as well. After the stored procedure call, the variables will be populated with return values.

If you want to have RETURN value as return from the PL/SQL call, then use FUNCTION. Please note that in case, you would be able to return only one variable as return variable.

2020 Update: An updated version of the function provided by many in this thread but now for C# 7.3 onwards:

Now you can restrict generic methods to enums types so you can write a single method extension to use it with all your enums like this:

The generic extension method:

public static string ATexto<T>(this T enumeración) where T : struct, Enum {
    var tipo = enumeración.GetType();
    return tipo.GetMember(enumeración.ToString())
    .Where(x => x.MemberType == MemberTypes.Field && ((FieldInfo)x).FieldType == tipo).First()
    .GetCustomAttribute<DisplayAttribute>()?.Name ?? enumeración.ToString();
} 

The enum:

public enum TipoImpuesto { 
IVA, INC, [Display(Name = "IVA e INC")]IVAeINC, [Display(Name = "No aplica")]NoAplica };

How to use it:

var tipoImpuesto = TipoImpuesto.IVAeINC;
var textoTipoImpuesto = tipoImpuesto.ATexto(); // Prints "IVA e INC".

Bonus, Enums with Flags: If you are dealing with normal enums the function above is enough, but if any of your enums can take multiple values with the use of flags then you will need to modify it like this (This code uses C#8 features):

    public static string ATexto<T>(this T enumeración) where T : struct, Enum {

        var tipo = enumeración.GetType();
        var textoDirecto = enumeración.ToString();

        string obtenerTexto(string textoDirecto) => tipo.GetMember(textoDirecto)
            .Where(x => x.MemberType == MemberTypes.Field && ((FieldInfo)x).FieldType == tipo)
            .First().GetCustomAttribute<DisplayAttribute>()?.Name ?? textoDirecto;

        if (textoDirecto.Contains(", ")) {

            var texto = new StringBuilder();
            foreach (var textoDirectoAux in textoDirecto.Split(", ")) {
                texto.Append($"{obtenerTexto(textoDirectoAux)}, ");
            }
            return texto.ToString()[0..^2];

        } else {
            return obtenerTexto(textoDirecto);
        }

    } 

The enum with flags:

[Flags] public enum TipoContribuyente {
    [Display(Name = "Común")] Común = 1, 
    [Display(Name = "Gran Contribuyente")] GranContribuyente = 2, 
    Autorretenedor = 4, 
    [Display(Name = "Retenedor de IVA")] RetenedorIVA = 8, 
    [Display(Name = "Régimen Simple")] RégimenSimple = 16 } 

How to use it:

var tipoContribuyente = TipoContribuyente.RetenedorIVA | TipoContribuyente.GranContribuyente;
var textoAux = tipoContribuyente.ATexto(); // Prints "Gran Contribuyente, Retenedor de IVA".

This work for me:

let inputValue = (swal.getPopup().querySelector('#inputValue ')as HTMLInputElement).value

You can not sort TreeMap on values.

A Red-Black tree based NavigableMap implementation. The map is sorted according to the natural ordering of its keys, or by a Comparator provided at map creation time, depending on which constructor is used You will need to provide comparator for Comparator<? super K> so your comparator should compare on keys.

To provide sort on values you will need SortedSet. Use

SortedSet<Map.Entry<String, Double>> sortedset = new TreeSet<Map.Entry<String, Double>>(
            new Comparator<Map.Entry<String, Double>>() {
                @Override
                public int compare(Map.Entry<String, Double> e1,
                        Map.Entry<String, Double> e2) {
                    return e1.getValue().compareTo(e2.getValue());
                }
            });

  sortedset.addAll(myMap.entrySet());

To give you an example

    SortedMap<String, Double> myMap = new TreeMap<String, Double>();
    myMap.put("a", 10.0);
    myMap.put("b", 9.0);
    myMap.put("c", 11.0);
    myMap.put("d", 2.0);
    sortedset.addAll(myMap.entrySet());
    System.out.println(sortedset);

Output:

  [d=2.0, b=9.0, a=10.0, c=11.0]

You can also do something like this -

 @RequestParam(value= "i", defaultValue = "20") Optional<Integer> i

if (Data_Array["XML_File"] != "") String xmlfile = Data_Array["XML_File"];

System.Convert.ChangeType(jtoken.ToString(), targetType);

or

JsonConvert.DeserializeObject(jtoken.ToString(), targetType);

--EDIT--

Uzair, Here is a complete example just to show you they work

string json = @"{
        ""id"" : 77239923,
        ""username"" : ""UzEE"",
        ""email"" : ""[email protected]"",
        ""name"" : ""Uzair Sajid"",
        ""twitter_screen_name"" : ""UzEE"",
        ""join_date"" : ""2012-08-13T05:30:23Z05+00"",
        ""timezone"" : 5.5,
        ""access_token"" : {
            ""token"" : ""nkjanIUI8983nkSj)*#)(kjb@K"",
            ""scope"" : [ ""read"", ""write"", ""bake pies"" ],
            ""expires"" : 57723
        },
        ""friends"" : [{
            ""id"" : 2347484,
            ""name"" : ""Bruce Wayne""
        },
        {
            ""id"" : 996236,
            ""name"" : ""Clark Kent""
        }]
    }";

var obj = (JObject)JsonConvert.DeserializeObject(json);
Type type = typeof(int);
var i1 = System.Convert.ChangeType(obj["id"].ToString(), type);
var i2 = JsonConvert.DeserializeObject(obj["id"].ToString(), type);

try something like this :

    DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
    Document dDoc = builder.parse("d://utf8test.xml");

    XPath xPath = XPathFactory.newInstance().newXPath();
    NodeList nodes = (NodeList) xPath.evaluate("//xml/ep/source/@type", dDoc, XPathConstants.NODESET);
    for (int i = 0; i < nodes.getLength(); i++) {
        Node node = nodes.item(i);
        System.out.println(node.getTextContent());
    }

please note the changes :

• we ask for a nodeset (XPathConstants.NODESET) and not only for a single node.
• the xpath is now //xml/ep/source/@type and not //xml/source/@type/text()

PS: can you add the tag java to your question ? thanks.

Apart from "readability", no. They're functionally equivalent.

_{("Readability" is in quotes because I hate == false and find ! much more readable. But others don't.)}

I just to solve this problem.

1. I set to null the value of list
2. I saved the object (It worked)
3. I set the new data to the object
4. I resaved the object
5. It works.!

Literal 0 is of type int and you can't assign int to std::string. Use mValue.clear() or assign an empty string mValue="".

Simple way:

public IDictionary<T, V> toDictionary<T, V>(Object objAttached)
{
    var dicCurrent = new Dictionary<T, V>();
    foreach (DictionaryEntry dicData in (objAttached as IDictionary))
    {
        dicCurrent.Add((T)dicData.Key, (V)dicData.Value);
    }
    return dicCurrent;
}

The following code does what is required

function doTest() {
  SpreadsheetApp.getActiveSheet().getRange('F2').setValue('Hello');
}

Try the following:

<script> 
 //Functions to open database and to create, insert data into tables

 getSelectedRow = function(val)
    {
        db.transaction(function(transaction) {
              transaction.executeSql('SELECT * FROM Employ where number = ?;',[parseInt(val)], selectedRowValues, errorHandler);

        });
    };
    selectedRowValues = function(transaction,results)
    {
         for(var i = 0; i < results.rows.length; i++)
         {
             var row = results.rows.item(i);
             alert(row['number']);
             alert(row['name']);                 
         }
    };
</script>

You don't have access to javascript variable names in SQL, you must pass the values to the Database.

For a search routine you should look to use Find, AutoFilter or variant array approaches. Range loops are nomally too slow, worse again if they use Select

The code below will look for the strText variable in a user selected range, it then adds any matches to a range variable rng2 which you can then further process

Option Explicit

Const strText As String = "%"

Sub ColSearch_DelRows()
    Dim rng1 As Range
    Dim rng2 As Range
    Dim rng3 As Range
    Dim cel1 As Range
    Dim cel2 As Range
    Dim strFirstAddress As String
    Dim lAppCalc As Long


    'Get working range from user
    On Error Resume Next
    Set rng1 = Application.InputBox("Please select range to search for " & strText, "User range selection", Selection.Address(0, 0), , , , , 8)
    On Error GoTo 0
    If rng1 Is Nothing Then Exit Sub

    With Application
        lAppCalc = .Calculation
        .ScreenUpdating = False
        .Calculation = xlCalculationManual
    End With

    Set cel1 = rng1.Find(strText, , xlValues, xlPart, xlByRows, , False)

    'A range variable - rng2 - is used to store the range of cells that contain the string being searched for
    If Not cel1 Is Nothing Then
        Set rng2 = cel1
        strFirstAddress = cel1.Address
        Do
            Set cel1 = rng1.FindNext(cel1)
            Set rng2 = Union(rng2, cel1)
        Loop While strFirstAddress <> cel1.Address
    End If

    If Not rng2 Is Nothing Then
        For Each cel2 In rng2
            Debug.Print cel2.Address & " contained " & strText
        Next
    Else
        MsgBox "No " & strText
    End If

    With Application
        .ScreenUpdating = True
        .Calculation = lAppCalc
    End With

End Sub

Default behaviour of PowerShell is just to dump everything that falls out of a pipeline without being picked up by another pipeline element or being assigned to a variable (or redirected) into Out-Host. What Out-Host does is obviously host-dependent.

Just letting things fall out of the pipeline is not a substitute for Write-Host which exists for the sole reason of outputting text in the host application.

If you want output, then use the Write-* cmdlets. If you want return values from a function, then just dump the objects there without any cmdlet.

If someone looking for a way to display decimal places even if it ends with ".00", use this:

String.Format("{0:n1}", value)

Reference:

https://docs.microsoft.com/pt-br/dotnet/standard/base-types/standard-numeric-format-strings#the-numeric-n-format-specifier

Of the top of my head, can you try to use the 'q' operator for the string literal

something like

insert all
  into domo_queries values (q'[select 
substr(to_char(max_data),1,4) as year,
substr(to_char(max_data),5,6) as month,
max_data
from dss_fin_user.acq_dashboard_src_load_success
where source = 'CHQ PeopleSoft FS']')
select * from dual;

Note that the single quotes of your predicate are not escaped, and the string sits between q'[...]'.

Suppose you were only allowed to use array then you could find the size of 2-d array by the following way.

  int ary[][5] = { {1, 2, 3, 4, 5},
                   {6, 7, 8, 9, 0}
                 };

  int rows =  sizeof ary / sizeof ary[0]; // 2 rows  

  int cols = sizeof ary[0] / sizeof(int); // 5 cols

Using Java 8 Streams:

Map<Object, Object> map = new HashMap<>();

String content = map.entrySet()
                    .stream()
                    .map(e -> e.getKey() + "=\"" + e.getValue() + "\"")
                    .collect(Collectors.joining(", "));

System.out.println(content);

I was getting this same error, but for me this was due to a method in a base class (in Project A) having the output type changed from a non-void type to void. A child class existed in Project B (which I didn't want used and had marked obsolete) that I missed when performing this update and hence started throwing this error.

1>CSC : error CS8104: An error occurred while writing the output file: System.NullReferenceException: Object reference not set to an instance of an object.

Original Code:

[Obsolete("Calling this method will throw an error")]
public override CompletionStatus Run()
{
    throw new CustomException("Run process not supported.");
}

Revised Code:

[Obsolete("Calling this method will throw an error")]
public override void Run()
{
    throw new CustomException("Run process not supported.");
}

In my case, I was defining a bean and autowiring it in the constructor of the same class file.

@SpringBootApplication
public class MyApplication {
    private MyBean myBean;

    public MyApplication(MyBean myBean) {
        this.myBean = myBean;
    }

    @Bean
    public MyBean myBean() {
        return new MyBean();
    }
}

My solution was to move the bean definition to another class file.

@Configuration
public CustomConfig {
    @Bean
    public MyBean myBean() {
        return new MyBean();
    }
}

While creating the object for the progressbar check the following.

This fails:

dialog = new ProgressDialog(getApplicationContext());

While adding the activities context works..

dialog = new ProgressDialog(MainActivity.this);

public long fillDataTempo(String table){
    String[] table = new String[1];
    tabela[0] = table; 
    ContentValues args = new ContentValues();
    args.put(DBOpenHelper.DATA_HORA, new Date().toString());
    args.put(DBOpenHelper.NOME_TABELA, nome_tabela);
    return db.update(DATABASE_TABLE, args, STRING + " LIKE ?" ,tabela);
}

Private Sub Main()
    Dim value = getValue()
    'do something with value
End Sub

Private Function getValue() As Integer
    Return 3
End Function

SQL Supports following types of affinities:

• TEXT
• NUMERIC
• INTEGER
• REAL
• BLOB

If the declared type for a column contains any of these "REAL", "FLOAT", or "DOUBLE" then the column has 'REAL' affinity.

I am going to throw you a curve ball here. If I have said it once I have said it a hundred times. Marshaling operations like Invoke or BeginInvoke are not always the best methods for updating the UI with worker thread progress.

In this case it usually works better to have the worker thread publish its progress information to a shared data structure that the UI thread then polls at regular intervals. This has several advantages.

• It breaks the tight coupling between the UI and worker thread that Invoke imposes.
• The UI thread gets to dictate when the UI controls get updated...the way it should be anyway when you really think about it.
• There is no risk of overrunning the UI message queue as would be the case if BeginInvoke were used from the worker thread.
• The worker thread does not have to wait for a response from the UI thread as would be the case with Invoke.
• You get more throughput on both the UI and worker threads.
• Invoke and BeginInvoke are expensive operations.

So in your calcClass create a data structure that will hold the progress information.

public class calcClass
{
  private double percentComplete = 0;

  public double PercentComplete
  {
    get 
    { 
      // Do a thread-safe read here.
      return Interlocked.CompareExchange(ref percentComplete, 0, 0);
    }
  }

  public testMethod(object input)
  {
    int count = 1000;
    for (int i = 0; i < count; i++)
    {
      Thread.Sleep(10);
      double newvalue = ((double)i + 1) / (double)count;
      Interlocked.Exchange(ref percentComplete, newvalue);
    }
  }
}

Then in your MainWindow class use a DispatcherTimer to periodically poll the progress information. Configure the DispatcherTimer to raise the Tick event on whatever interval is most appropriate for your situation.

public partial class MainWindow : Window
{
  public void YourDispatcherTimer_Tick(object sender, EventArgs args)
  {
    YourProgressBar.Value = calculation.PercentComplete;
  }
}

You can simply typecast, and it will do the conversion for you, e.g.

var with = (double?) jToken[key] ?? 100;

It will automatically return null if said key is not present in the object, so there's no need to test for it.

if you want to combine the 4 bytes into a single int you need to do

int i= (rno[0]<<24)&0xff000000|
       (rno[1]<<16)&0x00ff0000|
       (rno[2]<< 8)&0x0000ff00|
       (rno[3]<< 0)&0x000000ff;

I use 3 special operators | is the bitwise logical OR & is the logical AND and << is the left shift

in essence I combine the 4 8-bit bytes into a single 32 bit int by shifting the bytes in place and ORing them together

I also ensure any sign promotion won't affect the result with & 0xff

If you would like it to go back to first option try this:

   document.getElementById("select").selectedIndex = 0;

Thanks for enlightening us Cypawer.

I also tried this app https://play.google.com/store/apps/details?id=com.oneguyinabasement.leapwifi

and it worked flawlessly.

Make sure that the R you are pointing to is the correct one. I had a problem very similar to this, where an import got inserted by Eclipse that pointed to the System R file rather than the project one. It took a lot of head scratching. Hope this helps.

You could just use

DataGridView1.CurrentRow.Cells["ColumnName"].Value

Within your onDropDownChange handler, just make a jQuery AJAX call, passing in any data you need to pass up to your URL. You can handle successful and failure calls with the success and error options. In the success option, use the data contained in the data argument to do whatever rendering you need to do. Remember these are asynchronous by default!

function onDropDownChange(e) {
    var url = '/Home/Index/' + e.value;
    $.ajax({
      url: url,
      data: {}, //parameters go here in object literal form
      type: 'GET',
      datatype: 'json',
      success: function(data) { alert('got here with data'); },
      error: function() { alert('something bad happened'); }
    });
}

jQuery's AJAX documentation is here.

In Symfony forms, there are two different types of transformers and three different types of underlying data: In any form, the three different types of data are:

• Model data

  This is the data in the format used in your application (e.g. an Issue object). If you call Form::getData() or Form::setData(), you're dealing with the "model" data.

• Norm Data

  This is a normalized version of your data and is commonly the same as your "model" data (though not in our example). It's not commonly used directly.

• View Data

  This is the format that's used to fill in the form fields themselves. It's also the format in which the user will submit the data. When you call Form::submit($data), the $data is in the "view" data format.

The two different types of transformers help convert to and from each of these types of data:

• Model transformers:

  transform(): "model data" => "norm data"
  reverseTransform(): "norm data" => "model data"

• View transformers:

  transform(): "norm data" => "view data"
  reverseTransform(): "view data" => "norm data"

Which transformer you need depends on your situation.

To use the view transformer, call addViewTransformer().

If you want to get all form data:

$form->getData();

If you are after a specific form field (for example first_name):

$form->get('first_name')->getData();

An Iterator moves forward only, if it read it once, it's done. Your

m.get(itr2.next());

is reading the next value of itr2.next();, that is why you are missing a few (actually not a few, every other) keys.

If you want to launch VM by sending arguments, you should send VM arguments and not Program arguments.

Program arguments are arguments that are passed to your application, which are accessible via the "args" String array parameter of your main method. VM arguments are arguments such as System properties that are passed to the JavaSW interpreter. The Debug configuration above is essentially equivalent to:

java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3

The VM arguments go after the call to your Java interpreter (ie, 'java') and before the Java class. Program arguments go after your Java class.

Consider a program ArgsTest.java:

package test;

import java.io.IOException;

    public class ArgsTest {

        public static void main(String[] args) throws IOException {

            System.out.println("Program Arguments:");
            for (String arg : args) {
                System.out.println("\t" + arg);
            }

            System.out.println("System Properties from VM Arguments");
            String sysProp1 = "sysProp1";
            System.out.println("\tName:" + sysProp1 + ", Value:" + System.getProperty(sysProp1));
            String sysProp2 = "sysProp2";
            System.out.println("\tName:" + sysProp2 + ", Value:" + System.getProperty(sysProp2));

        }
    }

If given input as,

java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3 

in the commandline, in project bin folder would give the following result:

Program Arguments:
  pro1
  pro2
  pro3
System Properties from VM Arguments
  Name:sysProp1, Value:sp1
  Name:sysProp2, Value:sp2

setval('sequence_name', sequence_value)

Just use crontab -e and follow the tutorial here.

Look at point 3 for a guide on how to specify the frequency.

Based on your requirement, it should effectively be:

*/10 * * * * /usr/bin/python script.py

This is a simple way to do it without any triggers or sequences:

insert into WORKQUEUE (ID, facilitycode, workaction, description)
  values ((select max(ID)+1 from WORKQUEUE), 'J', 'II', 'TESTVALUES')

It worked for me but would not work with an empty table, I guess.

Note that you can also create your own structures using a Map.Entry as the main type, using its basic implementation AbstractMap.SimpleEntry. For instance, if you wanted to have an ordered list of entries, you could write:

List<Map.Entry<String, Integer>> entries = new ArrayList<>();
entries.add(new AbstractMap.SimpleEntry<String, Integer>(myStringValue, myIntValue));

And so on. From there, you have a list of tuples. Very useful when you want ordered tuples and a basic Map is a no-go.

Log.WriteLine("Value of CompanyName column:" + thisReader["CompanyName"]); 

Since all the players are numbered I would just use an ArrayList<Player>()

Something like

List<Player> players = new ArrayList<Player>();

System.out.printf("Give the number of the players ");
int number_of_players = scanner.nextInt();
scanner.nextLine(); // discard the rest of the line.

for(int k = 0;k < number_of_players; k++){
     System.out.printf("Give the name of player %d: ", k + 1);
     String name_of_player = scanner.nextLine();
     players.add(new Player(name_of_player,0)); //k=id and 0=score
}

for(Player player: players) {  
    System.out.println("Name of player in this round:" + player.getName());

You can increase the size of the memory through the use of commandline arguments.

Edit: Also see see this excellent question

EL interprets ${class.name} as described - the name becomes getName() on the assumption you are using explicit or implicit methods of generating getter/setters

You can override this behavior by explicitly identifying the name as a function: ${class.name()} This calls the function name() directly without modification.

In summary: I would be careful as to what code you copy. It is possible you are copying code which happens to work, rather than well chosen code.

In intnumber, parseInt is used and in floatnumber valueOf is used why so?

There is no good reason I can see. It's an inconsistent use of the APIs as you suspect.

Java is case sensitive, and there isn't any Readline() method. Perhaps you mean readLine().

DataInputStream.readLine() is deprecated in favour of using BufferedReader.readLine();

However, for your case, I would use the Scanner class.

Scanner sc = new Scanner(System.in);
int intNum = sc.nextInt();
float floatNum = sc.nextFloat();

If you want to know what a class does I suggest you have a quick look at the Javadoc.

Try this

textBox1.Text += "SomeText\r\n" 

you can also try

textBox1.Text += "SomeText" + Environment.NewLine;

Where \r is carriage return and \n is new line

I'm pretty sure GSON serializes/deserializes Maps and multiple-nested Maps (i.e. Map<String, Map<String, Object>>) just fine by default. The example provided I believe is nothing more than just a starting point if you need to do something more complex.

Check out the MapTypeAdapterFactory class in the GSON source: http://code.google.com/p/google-gson/source/browse/trunk/gson/src/main/java/com/google/gson/internal/bind/MapTypeAdapterFactory.java

So long as the types of the keys and values can be serialized into JSON strings (and you can create your own serializers/deserializers for these custom objects) you shouldn't have any issues.

With user defined functions, you have to declare every parameter, even if they have a default value.

The following would execute successfully:

IF dbo.CheckIfSFExists( 23, default ) = 0
    SET @retValue = 'bla bla bla;

public boolean  preencherjTextCombox (){
       int x = Integer.parseInt(TableModelo.getModel().getValueAt(TableModelo.getSelectedRow(),0).toString());

       modeloobj = modelosDAO.pesquisar(x);
       Combmarcass.getModel().setSelectedItem(modeloobj.getMarca());  
       txtCodigo.setText(String.valueOf(modeloobj.getCodigo()));
       txtDescricao.setText(String.valueOf(modeloobj.getDescricao()));
       txtPotencia.setText(String.valueOf(modeloobj.getPotencia()));  

       return true;
   }

You can use [];

var indexValue = Index[1];

Using async and await in a modern javascript Es6

const title = "title goes here";
const id = 1;

    try{
    const result = await Project.update(
          { title },
          { where: { id } }
        )
    }.catch(err => console.log(err));

you can return result ...

function saveAs(uri, filename) {
    var link = document.createElement('a');
    if (typeof link.download === 'string') {
        document.body.appendChild(link); // Firefox requires the link to be in the body
        link.download = filename;
        link.href = uri;
        link.click();
        document.body.removeChild(link); // remove the link when done
    } else {
        location.replace(uri);
    }
}

What will you have? You'll probably end up with a default search and a search that you load from somewhere. Default search requires a default constructor, so make one like Dismissile has already suggested.

If you load the search criteria from elsewhere, then you should probably have some mapping logic.

It's first worth adding (as this answer is still popular 6 years after I initially wrote it...) that the first thing you should consider is whether you should even use AFNetworking. NSURLSession was added in iOS 7 and means you don't need to use AFNetworking in many cases - and one less third party library is always a good thing.

For AFNetworking 3.0:

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *params = @{@"user[height]": height,
                         @"user[weight]": weight};
[manager POST:@"https://example.com/myobject" parameters:params progress:nil success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

For AFNetworking 2.0 (and also using the new NSDictionary syntax):

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = @{@"user[height]": height,
                         @"user[weight]": weight};
[manager POST:@"https://example.com/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

If you are stuck using AFNetworking 1.0, you need to do it this way:

NSURL *url = [NSURL URLWithString:@"https://example.com/"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                        height, @"user[height]",
                        weight, @"user[weight]",
                        nil];
[httpClient postPath:@"/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"Request Successful, response '%@'", responseStr);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"[HTTPClient Error]: %@", error.localizedDescription);
}];

Till i understand your question,you want to put two conditions to select a row to be deleted.for that,you need to do:

public void deleteEntry(long row,String key_name) {

      db.delete(DATABASE_TABLE, KEY_ROWID + "=" + row + " and " + KEY_NAME + "=" + key_name, null);

      /*if you just have key_name to select a row,you can ignore passing rowid(here-row) and use:

      db.delete(DATABASE_TABLE, KEY_NAME + "=" + key_name, null);
      */  

}

The solution works fine (thanks!), but if you want to avoid casting and leave the low level work to the JDK, you can use a DataOutputStream to write your int's and a DataInputStream to read them back in. They are automatically treated as unsigned bytes then:

For converting int's to binary bytes;

ByteArrayOutputStream bos = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(bos);
int val = 250;
dos.write(byteVal);
...
dos.flush();

Reading them back in:

// important to use a (non-Unicode!) encoding like US_ASCII or ISO-8859-1,
// i.e., one that uses one byte per character
ByteArrayInputStream bis = new ByteArrayInputStream(
   bos.toString("ISO-8859-1").getBytes("ISO-8859-1"));
DataInputStream dis = new DataInputStream(bis);
int byteVal = dis.readUnsignedByte();

Esp. useful for handling binary data formats (e.g. flat message formats, etc.)

TxtFarmerSize.Text = (int)reader[3];

The best way is to store the dates as a number, received by using the Calendar command.

//Building the table includes:
StringBuilder query=new StringBuilder();
query.append("CREATE TABLE "+TABLE_NAME+ " (");
query.append(COLUMN_ID+"int primary key autoincrement,");
query.append(COLUMN_DATETIME+" int)");

//And inserting the data includes this:
values.put(COLUMN_DATETIME, System.currentTimeMillis()); 

Why do this? First of all, getting values from a date range is easy. Just convert your date into milliseconds, and then query appropriately. Sorting by date is similarly easy. The calls to convert among various formats are also likewise easy, as I included. Bottom line is, with this method, you can do anything you need to do, no problems. It will be slightly difficult to read a raw value, but it more than makes up that slight disadvantage with being easily machine readable and usable. And in fact, it is relatively easy to build a reader (And I know there are some out there) that will automatically convert the time tag to date as such for easy of reading.

It's worth mentioning that the values that come out of this should be long, not int. Integer in sqlite can mean many things, anything from 1-8 bytes, but for almost all dates 64 bits, or a long, is what works.

EDIT: As has been pointed out in the comments, you have to use the cursor.getLong() to properly get the timestamp if you do this.

you may also want to encode and decode to/from base64

    function uncompress(str:String):ByteArray {
            import mx.utils.Base64Decoder;
            var dec:Base64Decoder = new Base64Decoder();
            dec.decode(str);
            var newByteArr:ByteArray=dec.toByteArray();        
            return newByteArr;
        }


    // Compress a ByteArray into a Base64 String.
    function compress(bytes:ByteArray):String { 
        import mx.utils.Base64Decoder; //Transform String in a ByteArray.
        import mx.utils.Base64Encoder; //Transform ByteArray in a readable string.
        var enc:Base64Encoder = new Base64Encoder();    
        enc.encodeBytes(bytes);
        return enc.drain().split("\n").join("");
    }

To set value

 $('#searchField').val('your_value');

to retrieve value

$('#searchField').val();

While probably not as clean looking as the IConvertible approach, you could always use the straightforward checking typeof(T) to return a T:

public static T ReturnType<T>(string stringValue)
{
    if (typeof(T) == typeof(int))
        return (T)(object)1;
    else if (typeof(T) == typeof(FooBar))
        return (T)(object)new FooBar(stringValue);
    else
        return default(T);
}

public class FooBar
{
    public FooBar(string something)
    {}
}

Yes there is a difference.

• The Runtime.exec(String) method takes a single command string that it splits into a command and a sequence of arguments.

• The ProcessBuilder constructor takes a (varargs) array of strings. The first string is the command name and the rest of them are the arguments. (There is an alternative constructor that takes a list of strings, but none that takes a single string consisting of the command and arguments.)

So what you are telling ProcessBuilder to do is to execute a "command" whose name has spaces and other junk in it. Of course, the operating system can't find a command with that name, and the command execution fails.

Oddly enough I found that if you parse from a string it works.

 int i = 0;
 Long l = Long.parseLong(String.valueOf(i));
 int back = Integer.parseInt(String.valueOf(l));

Win.

I saw an article yesterday that mentions an Object.__noSuchMethod__ property: JavascriptTips I've not had a chance to play around with it, so I don't know about browser support, but maybe you could use that in some way?

You can use serialize and base64_encode from the client side. After that, then use unserialize and base64_decode on the server side.

Like:

On the client side, use:

    $postvalue = array("a", "b", "c");
    $postvalue = base64_encode(serialize($array));

   // Your form hidden input
   <input type="hidden" name="result" value="<?php echo $postvalue; ?>">

On the server side, use:

    $postvalue = unserialize(base64_decode($_POST['result']));
    print_r($postvalue) // Your desired array data will be printed here

leDbConnection connection = 
new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Inventar.accdb");
DataSet1 DS = new DataSet1();
connection.Open();

OleDbDataAdapter DBAdapter = new OleDbDataAdapter(
@"SELECT tbl_Computer.*,  tbl_Besitzer.*
  FROM tbl_Computer 
  INNER JOIN tbl_Besitzer ON tbl_Computer.FK_Benutzer = tbl_Besitzer.ID 
  WHERE (((tbl_Besitzer.Vorname)='ma'));", 
connection);

It seems that you've omitted the value attribute in HTML markup.

Add it there as <input value="" ... >.

I know this is a fairly old question, but I ran into the same problem today and wasn't too interested in referencing all of MVVMLight just so I can use event triggers with event args. I have used MVVMLight in the past and it's a great framework, but I just don't want to use it for my projects any more.

What I did to resolve this problem was create an ULTRA minimal, EXTREMELY adaptable custom trigger action that would allow me to bind to the command and provide an event args converter to pass on the args to the command's CanExecute and Execute functions. You don't want to pass the event args verbatim, as that would result in view layer types being sent to the view model layer (which should never happen in MVVM).

Here is the EventCommandExecuter class I came up with:

public class EventCommandExecuter : TriggerAction<DependencyObject>
{
    #region Constructors

    public EventCommandExecuter()
        : this(CultureInfo.CurrentCulture)
    {
    }

    public EventCommandExecuter(CultureInfo culture)
    {
        Culture = culture;
    }

    #endregion

    #region Properties

    #region Command

    public ICommand Command
    {
        get { return (ICommand)GetValue(CommandProperty); }
        set { SetValue(CommandProperty, value); }
    }

    public static readonly DependencyProperty CommandProperty =
        DependencyProperty.Register("Command", typeof(ICommand), typeof(EventCommandExecuter), new PropertyMetadata(null));

    #endregion

    #region EventArgsConverterParameter

    public object EventArgsConverterParameter
    {
        get { return (object)GetValue(EventArgsConverterParameterProperty); }
        set { SetValue(EventArgsConverterParameterProperty, value); }
    }

    public static readonly DependencyProperty EventArgsConverterParameterProperty =
        DependencyProperty.Register("EventArgsConverterParameter", typeof(object), typeof(EventCommandExecuter), new PropertyMetadata(null));

    #endregion

    public IValueConverter EventArgsConverter { get; set; }

    public CultureInfo Culture { get; set; }

    #endregion

    protected override void Invoke(object parameter)
    {
        var cmd = Command;

        if (cmd != null)
        {
            var param = parameter;

            if (EventArgsConverter != null)
            {
                param = EventArgsConverter.Convert(parameter, typeof(object), EventArgsConverterParameter, CultureInfo.InvariantCulture);
            }

            if (cmd.CanExecute(param))
            {
                cmd.Execute(param);
            }
        }
    }
}

This class has two dependency properties, one to allow binding to your view model's command, the other allows you to bind the source of the event if you need it during event args conversion. You can also provide culture settings if you need to (they default to the current UI culture).

This class allows you to adapt the event args so that they may be consumed by your view model's command logic. However, if you want to just pass the event args on verbatim, simply don't specify an event args converter.

The simplest usage of this trigger action in XAML is as follows:

<i:Interaction.Triggers>
    <i:EventTrigger EventName="NameChanged">
        <cmd:EventCommandExecuter Command="{Binding Path=Update, Mode=OneTime}" EventArgsConverter="{x:Static c:NameChangedArgsToStringConverter.Default}"/>
    </i:EventTrigger>
</i:Interaction.Triggers>

If you needed access to the source of the event, you would bind to the owner of the event

<i:Interaction.Triggers>
    <i:EventTrigger EventName="NameChanged">
        <cmd:EventCommandExecuter 
            Command="{Binding Path=Update, Mode=OneTime}" 
            EventArgsConverter="{x:Static c:NameChangedArgsToStringConverter.Default}"
            EventArgsConverterParameter="{Binding ElementName=SomeEventSource, Mode=OneTime}"/>
    </i:EventTrigger>
</i:Interaction.Triggers>

(this assumes that the XAML node you're attaching the triggers to has been assigned x:Name="SomeEventSource"

This XAML relies on importing some required namespaces

xmlns:cmd="clr-namespace:MyProject.WPF.Commands"
xmlns:c="clr-namespace:MyProject.WPF.Converters"
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

and creating an IValueConverter (called NameChangedArgsToStringConverter in this case) to handle the actual conversion logic. For basic converters I usually create a default static readonly converter instance, which I can then reference directly in XAML as I have done above.

The benefit of this solution is that you really only need to add a single class to any project to use the interaction framework much the same way that you would use it with InvokeCommandAction. Adding a single class (of about 75 lines) should be much more preferable to an entire library to accomplish identical results.

NOTE

this is somewhat similar to the answer from @adabyron but it uses event triggers instead of behaviours. This solution also provides an event args conversion ability, not that @adabyron's solution could not do this as well. I really don't have any good reason why I prefer triggers to behaviours, just a personal choice. IMO either strategy is a reasonable choice.

Waqas Raja's answer with some LINQ lambda fun:

List<int> listValues = new List<int>();
Request.Form.AllKeys
    .Where(n => n.StartsWith("List"))
    .ToList()
    .ForEach(x => listValues.Add(int.Parse(Request.Form[x])));

Use Iterator.remove().

The result is not a String but a String[]. That's why you get this unsuspected printout.

[Ljava.lang.String is a signature of an array of String:

System.out.println(new String[]{});

I think it should be

verify(mockBar, times(2)).doSomething(...)

Sample from mockito javadoc:

ArgumentCaptor<Person> peopleCaptor = ArgumentCaptor.forClass(Person.class);
verify(mock, times(2)).doSomething(peopleCaptor.capture());

List<Person> capturedPeople = peopleCaptor.getAllValues();
assertEquals("John", capturedPeople.get(0).getName());
assertEquals("Jane", capturedPeople.get(1).getName());

Besides using ProcessBuilder as suggested Senthil, be sure to read and implement all the recommendations of When Runtime.exec() won't.

enum A {a,b,c}
enum B extends A {d}
/*B is {a,b,c,d}*/

can be written as:

public enum All {
    a       (ClassGroup.A,ClassGroup.B),
    b       (ClassGroup.A,ClassGroup.B),
    c       (ClassGroup.A,ClassGroup.B),
    d       (ClassGroup.B) 
...

• ClassGroup.B.getMembers() contains {a,b,c,d}

How it can be useful: Let say we want something like: We have events and we are using enums. Those enums can be grouped by similar processing. If we have operation with many elements, then some events starts operation, some are just step and other end the operation. To gather such operation and avoid long switch case we can group them as in example and use:

if(myEvent.is(State_StatusGroup.START)) makeNewOperationObject()..
if(myEnum.is(State_StatusGroup.STEP)) makeSomeSeriousChanges()..
if(myEnum.is(State_StatusGroup.FINISH)) closeTransactionOrSomething()..

Example:

public enum AtmOperationStatus {
STARTED_BY_SERVER       (State_StatusGroup.START),
SUCCESS             (State_StatusGroup.FINISH),
FAIL_TOKEN_TIMEOUT      (State_StatusGroup.FAIL, 
                    State_StatusGroup.FINISH),
FAIL_NOT_COMPLETE       (State_StatusGroup.FAIL,
                    State_StatusGroup.STEP),
FAIL_UNKNOWN            (State_StatusGroup.FAIL,
                    State_StatusGroup.FINISH),
(...)

private AtmOperationStatus(StatusGroupInterface ... pList){
    for (StatusGroupInterface group : pList){
        group.addMember(this);
    }
}
public boolean is(StatusGroupInterface with){
    for (AtmOperationStatus eT : with.getMembers()){
        if( eT .equals(this))   return true;
    }
    return false;
}
// Each group must implement this interface
private interface StatusGroupInterface{
    EnumSet<AtmOperationStatus> getMembers();
    void addMember(AtmOperationStatus pE);
}
// DEFINING GROUPS
public enum State_StatusGroup implements StatusGroupInterface{
    START, STEP, FAIL, FINISH;

    private List<AtmOperationStatus> members = new LinkedList<AtmOperationStatus>();

    @Override
    public EnumSet<AtmOperationStatus> getMembers() {
        return EnumSet.copyOf(members);
    }

    @Override
    public void addMember(AtmOperationStatus pE) {
        members.add(pE);
    }
    static { // forcing initiation of dependent enum
        try {
            Class.forName(AtmOperationStatus.class.getName()); 
        } catch (ClassNotFoundException ex) { 
            throw new RuntimeException("Class AtmEventType not found", ex); 
        }
    }
}
}
//Some use of upper code:
if (p.getStatus().is(AtmOperationStatus.State_StatusGroup.FINISH)) {
    //do something
}else if (p.getStatus().is(AtmOperationStatus.State_StatusGroup.START)) {
    //do something      
}  

Add some more advanced:

public enum AtmEventType {

USER_DEPOSIT        (Status_EventsGroup.WITH_STATUS,
              Authorization_EventsGroup.USER_AUTHORIZED,
              ChangedMoneyAccountState_EventsGroup.CHANGED,
              OperationType_EventsGroup.DEPOSIT,
              ApplyTo_EventsGroup.CHANNEL),
SERVICE_DEPOSIT     (Status_EventsGroup.WITH_STATUS,
              Authorization_EventsGroup.TERMINAL_AUTHORIZATION,
              ChangedMoneyAccountState_EventsGroup.CHANGED,
              OperationType_EventsGroup.DEPOSIT,
              ApplyTo_EventsGroup.CHANNEL),
DEVICE_MALFUNCTION  (Status_EventsGroup.WITHOUT_STATUS,
              Authorization_EventsGroup.TERMINAL_AUTHORIZATION,
              ChangedMoneyAccountState_EventsGroup.DID_NOT_CHANGED,
              ApplyTo_EventsGroup.DEVICE),
CONFIGURATION_4_C_CHANGED(Status_EventsGroup.WITHOUT_STATUS,
              ApplyTo_EventsGroup.TERMINAL,
              ChangedMoneyAccountState_EventsGroup.DID_NOT_CHANGED),
(...)

At above if we have some fail (myEvent.is(State_StatusGroup.FAIL)) then iterating by previous events we can easily check if we must revert money transfer by:

if(myEvent2.is(ChangedMoneyAccountState_EventsGroup.CHANGED)) rollBack()..

It can be useful for:

1. including explicite meta-data about processing logic, less to remember
2. implementing some of multi-inheritance
3. we don't want to use class structures, ex. for sending short status messages

The best way to get good control over the colorbar position is to give it its own axis. Like so:

# What I imagine your plotting looks like so far
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(your_data)

# Now adding the colorbar
cbaxes = fig.add_axes([0.8, 0.1, 0.03, 0.8]) 
cb = plt.colorbar(ax1, cax = cbaxes)  

The numbers in the square brackets of add_axes refer to [left, bottom, width, height], where the coordinates are just fractions that go from 0 to 1 of the plotting area.

For the record, the file Microsoft.Cpp.Default.props can modify the env var VCTargetsPath and make subsequent usages of that var incorrect. I had that problem and solved it by setting VCTargetsPath10 and VCTargetsPath11 to the same value than VCTargetsPath.

This should be adapted according to the VS version you are using.

It's the first result on Google: http://docs.python.org/library/stdtypes.html#string-formatting

See also the new format() function: http://docs.python.org/library/stdtypes.html#str.format

Just use the *args parameter, which allows you to pass as many arguments as you want after your a,b,c. You would have to add some logic to map args->c,d,e,f but its a "way" of overloading.

def myfunc(a,b, *args, **kwargs):
   for ar in args:
      print ar
myfunc(a,b,c,d,e,f)

And it will print values of c,d,e,f

Similarly you could use the kwargs argument and then you could name your parameters.

def myfunc(a,b, *args, **kwargs):
      c = kwargs.get('c', None)
      d = kwargs.get('d', None)
      #etc
myfunc(a,b, c='nick', d='dog', ...)

And then kwargs would have a dictionary of all the parameters that are key valued after a,b

If you use Spring you can:

1) create a log4j configuration file, e.g. "/WEB-INF/classes/log4j-myapp.properties" DO NOT name it "log4j.properties"

Example:

log4j.rootLogger=ERROR, stdout, rollingFile

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n

log4j.appender.rollingFile=org.apache.log4j.RollingFileAppender
log4j.appender.rollingFile.File=${myWebapp-instance-root}/WEB-INF/logs/application.log
log4j.appender.rollingFile.MaxFileSize=512KB
log4j.appender.rollingFile.MaxBackupIndex=10
log4j.appender.rollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.rollingFile.layout.ConversionPattern=%d %p [%c] - %m%n
log4j.appender.rollingFile.Encoding=UTF-8

We'll define "myWebapp-instance-root" later on point (3)

2) Specify config location in web.xml:

<context-param>
  <param-name>log4jConfigLocation</param-name>
  <param-value>/WEB-INF/classes/log4j-myapp.properties</param-value>
</context-param>

3) Specify a unique variable name for your webapp's root, e.g. "myWebapp-instance-root"

<context-param>
  <param-name>webAppRootKey</param-name>
  <param-value>myWebapp-instance-root</param-value>
</context-param>

4) Add a Log4jConfigListener:

<listener>
  <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

If you choose a different name, remember to change it in log4j-myapp.properties, too.

See my article (Italian only... but it should be understandable): http://www.megadix.it/content/configurare-path-relativi-log4j-utilizzando-spring

UPDATE (2009/08/01) I've translated my article to English: http://www.megadix.it/node/136

Objective-C:

NSString to NSData:

NSString* str= @"string";
NSData* data=[str dataUsingEncoding:NSUTF8StringEncoding];

NSData to NSString:

NSString* newStr = [[NSString alloc] initWithData:theData encoding:NSUTF8StringEncoding];

Swift:

String to Data:

var testString = "string"
var somedata = testString.data(using: String.Encoding.utf8)

Data to String:

var backToString = String(data: somedata!, encoding: String.Encoding.utf8) as String!

i think you just have to assign the items from Author list to a new list to take that effect.

//assume oldAuthor is the old list
Author newAuthorList = (select x from oldAuthor where x.firstname!="Bob" select x).ToList();
oldAuthor = newAuthorList;
newAuthorList = null;

Nope, there is not. You'll have to use the primitive long data type and deal with signedness issues, or use a class such as BigInteger.

The CSS to center text in your td elements is

td {
  text-align: center;
  vertical-align: middle;
}

Suppose your query is "select id,name from users where rollNo = 1001".

Here query will return a object with id and name column. Your Response class is like bellow:

public class UserObject{
        int id;
        String name;
        String rollNo;

        public UserObject(Object[] columns) {
            this.id = (columns[0] != null)?((BigDecimal)columns[0]).intValue():0;
            this.name = (String) columns[1];
        }

        public int getId() {
            return id;
        }

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

        public String getName() {
            return name;
        }

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

        public String getRollNo() {
            return rollNo;
        }

        public void setRollNo(String rollNo) {
            this.rollNo = rollNo;
        }
    }

here UserObject constructor will get a Object Array and set data with object.

public UserObject(Object[] columns) {
            this.id = (columns[0] != null)?((BigDecimal)columns[0]).intValue():0;
            this.name = (String) columns[1];
        }

Your query executing function is like bellow :

public UserObject getUserByRoll(EntityManager entityManager,String rollNo) {

        String queryStr = "select id,name from users where rollNo = ?1";
        try {
            Query query = entityManager.createNativeQuery(queryStr);
            query.setParameter(1, rollNo);

            return new UserObject((Object[]) query.getSingleResult());
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        }
    }

Here you have to import bellow packages:

import javax.persistence.Query;
import javax.persistence.EntityManager;

Now your main class, you have to call this function. First you have to get EntityManager and call this getUserByRoll(EntityManager entityManager,String rollNo) function. Calling procedure is given bellow:

@PersistenceContext
private EntityManager entityManager;

UserObject userObject = getUserByRoll(entityManager,"1001");

Now you have data in this userObject.

Here is Imports

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

Note:

query.getSingleResult() return a array. You have to maintain the column position and data type.

select id,name from users where rollNo = ?1 

query return a array and it's [0] --> id and [1] -> name.

Thanks :)

In case that needed here is how we solved insert of array

request is from postman (You will look at "guests" )

 {
  "author_id" : 3,
  "name" : "World War II",
  "date" : "01 09 1939", 
  "time" : "16 : 22",
  "location" : "39.9333635/32.8597419",
  "guests" : [2, 3, 1337, 1942, 1453]
}

And how we scripted

var express = require('express');
var utils = require('./custom_utils.js');

module.exports = function(database){
    var router = express.Router();

    router.post('/', function(req, res, next) {
        database.query('INSERT INTO activity (author_id, name, date, time, location) VALUES (?, ?, ?, ?, ?) ON DUPLICATE KEY UPDATE name = VALUES(name), date = VALUES(date), time = VALUES(time), location = VALUES(location)', 
                [req.body.author_id, req.body.name, req.body.date, req.body.time, req.body.location], function(err, results, fields){
            if(err){
                console.log(err);
                res.json({ status: utils.respondMSG.DB_ERROR });
            }
            else {
                var act_id = results.insertId;
                database.query('INSERT INTO act_guest (user_id, activity_id, status) VALUES ? ON DUPLICATE KEY UPDATE status = VALUES(status)', 
                        [Array.from(req.body.guests).map(function(g){ return [g, act_id, 0]; })], function(err, results, fields){
                    if(err){
                        console.log(err);
                        res.json({ status: utils.respondMSG.DB_ERROR });
                    }
                    else {
                        res.json({ 
                            status: utils.respondMSG.SUCCEED,
                            data: {
                                activity_id : act_id
                            }
                        });
                    }
                });
            }
        });
    });
    return router;
};

FEATURE_NO_TITLE works when creating a dialog from scratch, as in:

Dialog dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

But it doesn't work when creating an AlertDialog (or using the Builder), because it already disables the title and use a custom one internally.

I have looked at the SDK sources, and I think that it can't be worked around. So to remove the top spacing, the only solution is to create a custom dialog from scratch IMO, by using the Dialog class directly.

Also, one can do that with a style, eg in styles.xml:

<style name="FullHeightDialog" parent="android:style/Theme.Dialog">
   <item name="android:windowNoTitle">true</item>
</style>

And then:

Dialog dialog = new Dialog(context, R.style.FullHeightDialog);

• First, Download MySQL connector jar file, This is the latest jar file as of today [mysql-connector-java-8.0.21].

• Add the Jar file to your workspace [build path].

• Then Create a new Connection object from the DriverManager class, so you could use this Connection object to execute queries.

• Define the database name, userName, and Password for your connection.

• Use the resultSet to get the data based one the column name from your database table.

Sample code is here:

public class JdbcMySQLExample{

public static void main(String[] args) {

    String url = "jdbc:mysql://localhost:3306/YOUR_DB_NAME?useSSL=false";
    String user = "root";
    String password = "root";
    
    String query = "SELECT * from YOUR_TABLE_NAME";

    try (Connection con = DriverManager.getConnection(url, user, password);
        Statement st = con.createStatement();
        ResultSet rs = st.executeQuery(query)) {

        if (rs.next()) {
            
            System.out.println(rs.getString(1));
        }

    } catch (SQLException ex) {
          System.out.println(ex);
       
    } 
}

I used StoredProcedureEFCore nuget package by https://github.com/verdie-g/StoredProcedureEFCore,EnterpriseLibrary.Data.NetCore,EFCor.SqlServer,EFCore.Tools

I tried DbFirst approach with {Repository pattern}.. i think so

startup.cs

ConfigureServices(IServiceCollection services){
    services.AddDbContext<AppDbContext>(opt => opt
                   .UseSqlServer(Configuration.GetConnectionString("SampleConnectionString")));
    services.AddScoped<ISomeDAL, SomeDAL>();

}
            
    public  class AppDbContext : DbContext{
public AppDbContext(DbContextOptions<AppDbContext> options) : base(options)
    {}
}

ISomeDAl Interface has {GetPropertiesResponse GetAllPropertiesByCity(int CityId);}

public class SomeDAL : ISomeDAL
{
     private readonly AppDbContext context;

     public SomeDAL(AppDbContext context)
         {
             this.context = context;
         }
     public  GetPropertiesResponse GetAllPropertiesByCity(int CityId)
     {
         //Create Required Objects for response 
         //wont support ref Objects through params
         context.LoadStoredProc(SQL_STATEMENT)
            .AddParam("CityID", CityId).Exec( r =>
             {
                  while (r.Read())
                  {

                       ORMapping<GenericRespStatus> orm = new  ORMapping<GenericRespStatus>();
                       orm.AssignObject(r, _Status);
                  }

                  if (r.NextResult())
                  {

                       while (r.Read())

                           _propertyDetailsResult.Add(Property);
                       }
                  }    
           });
    return new GetPropertiesResponse{Status=_Status,PropertyDetails=_propertyDetailsResult}; 
    }
}

public class GetPropertiesResponse

     public GetPropertiesResponse()
         {
             PropertyDetails = new List<Property>();
         }
}
public class GenericRespStatus

I tried to manage using the below command. This will write the output in log file as well as print on console.

#!/bin/bash

# Log Location on Server.
LOG_LOCATION=/home/user/scripts/logs
exec > >(tee -i $LOG_LOCATION/MylogFile.log)
exec 2>&1

echo "Log Location should be: [ $LOG_LOCATION ]"

Please note: This is bash code so if you run it using sh it will through syntax error

Just use Analyze | Inspect Code with appropriate inspection enabled (Unused declaration under Declaration redundancy group).

Using IntelliJ 11 CE you can now "Analyze | Run Inspection by Name ... | Unused declaration"

For me the following works good. Just add it. You can edit it as per your requirement. This is just a nice trick I use.

text-shadow : 0 0 0 #your-font-color;

You can use in this way using bootstrap css. Just remove the active class if already assinged to any row and reassign to the current row.

    $(".table tr").each(function () {
        $(this).attr("class", "");
    });
    $(this).attr("class", "active");

The following jQuery selects div nodes that contain text but have no children, which are the leaf nodes of the DOM tree.

I had a similar issue while using Sublime Text-3. After making new changes in the code and saving it, when I tried the git add ./status commands the response was "branch already-up to date". I figured out, regardless saving the updates in the text editor, the file was actually unchanged. Opening file in other editor and saving the changes worked for me.

If it is an auto generated key, then you can use Statement#getGeneratedKeys() for this. You need to call it on the same Statement as the one being used for the INSERT. You first need to create the statement using Statement.RETURN_GENERATED_KEYS to notify the JDBC driver to return the keys.

Here's a basic example:

public void create(User user) throws SQLException {
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL_INSERT,
                                      Statement.RETURN_GENERATED_KEYS);
    ) {
        statement.setString(1, user.getName());
        statement.setString(2, user.getPassword());
        statement.setString(3, user.getEmail());
        // ...

        int affectedRows = statement.executeUpdate();

        if (affectedRows == 0) {
            throw new SQLException("Creating user failed, no rows affected.");
        }

        try (ResultSet generatedKeys = statement.getGeneratedKeys()) {
            if (generatedKeys.next()) {
                user.setId(generatedKeys.getLong(1));
            }
            else {
                throw new SQLException("Creating user failed, no ID obtained.");
            }
        }
    }
}

Note that you're dependent on the JDBC driver as to whether it works. Currently, most of the last versions will work, but if I am correct, Oracle JDBC driver is still somewhat troublesome with this. MySQL and DB2 already supported it for ages. PostgreSQL started to support it not long ago. I can't comment about MSSQL as I've never used it.

For Oracle, you can invoke a CallableStatement with a RETURNING clause or a SELECT CURRVAL(sequencename) (or whatever DB-specific syntax to do so) directly after the INSERT in the same transaction to obtain the last generated key. See also this answer.

While looking at your code, the only thing I see wrong, is when you try to load the second database:

$DB2=$this->load->database($config);

When you want to retrieve the database object, you have to pass TRUE in the second argument.

From the Codeigniter User Guide:

By setting the second parameter to TRUE (boolean) the function will return the database object.

So, your code should instead be:

$DB2=$this->load->database($config, TRUE);

That will make it work.

I had the same problem (Repository not found) due to the fact that initially I logged in with an incorrect GitHub account. To fix it:

1. Open Control Panel from the Start menu.
2. Select User Accounts.
3. Select "Manage your credentials" in the left hand menu.
4. Delete any credentials related to Git or GitHub.

The problem may come from running the project from visual studio on IIS while being on the wrong opened tab on visual studio, so the solution is either opening the right tab (the webform you want to test on your browser) or as others suggested in the other answers, right click on the webform that you want to set as a homepage then click on 'Set As A Start Page'.

Using the Perl API you can get it this way: first you send a message to the bot from Telegram, then issue a getUpdates and the chat id must be there:

#!/usr/bin/perl

use Data::Dumper;
use WWW::Telegram::BotAPI;

my $TOKEN = 'blablabla';
my $api = WWW::Telegram::BotAPI->new (
    token => $TOKEN
) or die "I can't connect";

my $out = $api->api_request ('getUpdates');
warn Dumper($out);
my $chat_id = $out->{result}->[0]->{message}->{chat}->{id};
print "chat_id=$chat_id\n";

The id should be in chat_id but it may depend of the result, so I also added a dump of the whole result.

You can install the Perl API from https://github.com/Robertof/perl-www-telegram-botapi. It depends on your system but I installed easily running this on my Linux server:

$ sudo cpan WWW::Telegram::BotAPI

The whole lot is encrypted^† - all the headers. That's why SSL on vhosts doesn't work too well - you need a dedicated IP address because the Host header is encrypted.

^†The Server Name Identification (SNI) standard means that the hostname may not be encrypted if you're using TLS. Also, whether you're using SNI or not, the TCP and IP headers are never encrypted. (If they were, your packets would not be routable.)

SELECT 'Free &' || ' Clear' FROM DUAL;

$d="05/Feb/2010:14:00:01";
$dr= date_create_from_format('d/M/Y:H:i:s', $d);
echo $dr->format('Y-m-d H:i:s');

here you get date string, give format specifier in ->format() according to format needed

Also it may cause some warnigs in logs like a Cglib2AopProxy Unable to proxy method. And many other reasons for this are described here Why always have single implementaion interfaces in service and dao layers?

It is more Ruby-like to ask objects whether they respond to a method you need or not, using respond_to?. This allows both minimal interface and implementation unaware programming.

It is not always applicable of course, thus there is still a possibility to ask about more conservative understanding of "type", which is class or a base class, using the methods you're asking about.

Translating @samwize's Extension to Swift 4:

extension UITapGestureRecognizer {
    func didTapAttributedTextInLabel(label: UILabel, inRange targetRange: NSRange) -> Bool {
        guard let attrString = label.attributedText else {
            return false
        }

        let layoutManager = NSLayoutManager()
        let textContainer = NSTextContainer(size: .zero)
        let textStorage = NSTextStorage(attributedString: attrString)

        layoutManager.addTextContainer(textContainer)
        textStorage.addLayoutManager(layoutManager)

        textContainer.lineFragmentPadding = 0
        textContainer.lineBreakMode = label.lineBreakMode
        textContainer.maximumNumberOfLines = label.numberOfLines
        let labelSize = label.bounds.size
        textContainer.size = labelSize

        let locationOfTouchInLabel = self.location(in: label)
        let textBoundingBox = layoutManager.usedRect(for: textContainer)
        let textContainerOffset = CGPoint(x: (labelSize.width - textBoundingBox.size.width) * 0.5 - textBoundingBox.origin.x, y: (labelSize.height - textBoundingBox.size.height) * 0.5 - textBoundingBox.origin.y)
        let locationOfTouchInTextContainer = CGPoint(x: locationOfTouchInLabel.x - textContainerOffset.x, y: locationOfTouchInLabel.y - textContainerOffset.y)
        let indexOfCharacter = layoutManager.characterIndex(for: locationOfTouchInTextContainer, in: textContainer, fractionOfDistanceBetweenInsertionPoints: nil)
        return NSLocationInRange(indexOfCharacter, targetRange)
    }
}

To set up the recognizer (once you colored the text and stuff):

lblTermsOfUse.isUserInteractionEnabled = true
lblTermsOfUse.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleTapOnLabel(_:))))

...then the gesture recognizer:

@objc func handleTapOnLabel(_ recognizer: UITapGestureRecognizer) {
    guard let text = lblAgreeToTerms.attributedText?.string else {
        return
    }

    if let range = text.range(of: NSLocalizedString("_onboarding_terms", comment: "terms")),
        recognizer.didTapAttributedTextInLabel(label: lblAgreeToTerms, inRange: NSRange(range, in: text)) {
        goToTermsAndConditions()
    } else if let range = text.range(of: NSLocalizedString("_onboarding_privacy", comment: "privacy")),
        recognizer.didTapAttributedTextInLabel(label: lblAgreeToTerms, inRange: NSRange(range, in: text)) {
        goToPrivacyPolicy()
    }
}

I've worked with <body>and <div class="wrapper">

When popup opens ...

<body> gets a height of 100% and an overflow:hidden

<div class="wrapper"> gets position:relative;overflow:hidden;height:100%;

I use JS/jQuery to get the actual scrollposition of the page and store the value as data-attribut to body

Then i scroll to the scrollposition in the .wrapper DIV (not in window)

Here is my solution:

JS/jQuery:

// when popup opens

$('body').attr( 'data-pos', $(window).scrollTop()); // get actual scrollpos
$('body').addClass('locked'); // add class to body
$('.wrapper').scrollTop( $('body').attr( 'data-pos' ) ); // let wrapper scroll to scrollpos

// when popup close

$("body").removeClass('locked');
$( window ).scrollTop( $('body').attr( 'data-pos' ));

CSS:

body.locked {position:relative;overflow:hidden;height:100%;}
body.locked .wrapper {position:relative;overflow:hidden;height:100%;}

It works well on both sides ... desktop & mobile (iOS).

Tipps and improvements are welcome :)

Cheers!

Use this:

SELECT * 
FROM tablename 
ORDER BY priority desc, FIELD(name, "core")

With modern C++ compilers you can use sanitizers to track.

Sample example :

My program:

$cat d_free.cxx 
#include<iostream>

using namespace std;

int main()

{
   int * i = new int();
   delete i;
   //i = NULL;
   delete i;
}

Compile with address sanitizers :

# g++-7.1 d_free.cxx -Wall -Werror -fsanitize=address -g

Execute :

# ./a.out 
=================================================================
==4836==ERROR: AddressSanitizer: attempting double-free on 0x602000000010 in thread T0:

To learn more about sanitizers you can check this or this or any modern c++ compilers (e.g. gcc, clang etc.) documentations.

Use onClick event to clear value of target input, each time user clicks on field. This ensures that the onChange event will be triggered for the same file as well. Worked for me :)

onInputClick = (event) => {
    event.target.value = ''
}

<input type="file" onChange={onFileChanged} onClick={onInputClick} />

Using TypeScript

onInputClick = ( event: React.MouseEvent<HTMLInputElement, MouseEvent>) => {
    const element = event.target as HTMLInputElement
    element.value = ''
}

BR is an inline element, not a block element.

So, you need:

 br.Underline{
    border-bottom:1px dashed black;
    display: block;
  }

Otherwise, browsers that are a little pickier about such things will refuse to apply borders to your BR elements, since inline elements don't have borders, padding, or margins.

You could do something like this:

Convert.ToDate(month + " 01, 1900").Month

Try like

$('.printMe').click(function(){
     window.print();
});

or if you want to print selected area try like

$('.printMe').click(function(){
     $("#outprint").print();
});

openssl pkcs12 -inkey bob_key.pem -in bob_cert.cert -export -out bob_pfx.pfx

String text = "text";
text += new String(" ");

So here's how to do that:

In the bottom bar of VSCode, you'll see the label UTF-8. Click it. A popup opens. Click Save with encoding. You can now pick a new encoding for that file.

Alternatively, you can change the setting globally in Workspace/User settings using the setting "files.encoding": "utf8". If using the graphical settings page in VSCode, simply search for encoding. Do note however that this only applies to newly created files.

It seems that this can't be done, not at least with current versions of IE (6 and 7).

IE supports form attribute accept-charset, but only if its value is 'utf-8'.

The solution is to modify server A to produce encoding 'ISO-8859-1' for page that contains the form.

The simplest way would be to directly subtract the date objects from one another.

For example:

var hours = Math.abs(date1 - date2) / 36e5;

The subtraction returns the difference between the two dates in milliseconds. 36e5 is the scientific notation for 60*60*1000, dividing by which converts the milliseconds difference into hours.

You've nearly got it. The problem is that the Class Under Test (CUT) is not built for unit testing - it has not really been TDD'd.

Think of it like this…

• I need to test a function of a class - let's call it myFunction
• That function makes a call to a function on another class/service/database
• That function also calls another method on the CUT

In the unit test

• Should create a concrete CUT or @Spy on it
• You can @Mock all of the other class/service/database (i.e. external dependencies)
• You could stub the other function called in the CUT but it is not really how unit testing should be done

In order to avoid executing code that you are not strictly testing, you could abstract that code away into something that can be @Mocked.

In this very simple example, a function that creates an object will be difficult to test

public void doSomethingCool(String foo) {
    MyObject obj = new MyObject(foo);

    // can't do much with obj in a unit test unless it is returned
}

But a function that uses a service to get MyObject is easy to test, as we have abstracted the difficult/impossible to test code into something that makes this method testable.

public void doSomethingCool(String foo) {
    MyObject obj = MyObjectService.getMeAnObject(foo);
}

as MyObjectService can be mocked and also verified that .getMeAnObject() is called with the foo variable.

Use count()

if (count($my_array) > 1) {
// do
}

this page explains it pretty well http://phparraylength.com/

Please read the whole answer before attempting to run with sudo

Try running sudo /dvtcolorconvert.rb ~/Themes/ObsidianCode.xccolortheme

The sudo command executes the commands which follow it with 'superuser' or 'root' privileges. This should allow you to execute almost anything from the command line. That said, DON'T DO THIS! If you are running a script on your computer and don't need it to access core components of your operating system (I'm guessing you're not since you are invoking the script on something inside your home directory (~/)), then it should be running from your home directory, ie:

~/dvtcolorconvert.rb ~/Themes/ObsidianCode.xccolortheme

Move it to ~/ or a sub directory and execute from there. You should never have permission issues there and there wont be a risk of it accessing or modifying anything critical to your OS.

If you are still having problems you can check the permissions on the file by running ls -l while in the same directory as the ruby script. You will get something like this:

$ ls -l  
total 13  
drwxr-xr-x    4 or019268 Administ    12288 Apr 10 18:14 TestWizard  
drwxr-xr-x    4 or019268 Administ     4096 Aug 27 12:41 Wizard.Controls  
drwxr-xr-x    5 or019268 Administ     8192 Sep  5 00:03 Wizard.UI  
-rw-r--r--    1 or019268 Administ     1375 Sep  5 00:03 readme.txt

You will notice that the readme.txt file says -rw-r--r-- on the left. This shows the permissions for that file. The 9 characters from the right can be split into groups of 3 characters of 'rwx' (read, write, execute). If I want to add execute rights to this file I would execute chmod 755 readme.txt and that permissions portion would become rwxr-xr-x. I can now execute this file if I want to by running ./readme.txt (./ tells the bash to look in the current directory for the intended command rather that search the $PATH variable).

schluchc alludes to looking at the man page for chmod, do this by running man chmod. This is the best way to get documentation on a given command, man <command>

Try this:

export PATH=/home/your_username/anaconda3/bin:$PATH
in ~/.bashrc

Then source ~/.bashrc This works for me for the same problem.

A pure javascript solution (without jQuery):

const SEARCH_DELAY = 100; // in ms

// it may run indefinitely. TODO: make it cancellable, using Promise's `reject`
function waitForElementToBeAdded(cssSelector) {
  return new Promise((resolve) => {
    const interval = setInterval(() => {
      if (element = document.querySelector(cssSelector)) {
        clearInterval(interval);
        resolve(element);
      }
    }, SEARCH_DELAY);
  });
}

console.log(await waitForElementToBeAdded('#main'));

Escape the | character using a backtick

get-content c:\new\temp_*.txt | select-string -pattern 'H`|159' -notmatch | Out-File c:\new\newfile.txt

No, a view is static. One thing you can do (depending on the version of SQl server) is index a view.

In your example (querying only one table), an indexed view has no benefit to simply querying the table with an index on it, but if you are doing a lot of joins on tables with join conditions, an indexed view can greatly improve performance.

If you want to print an arraylist with integer numbers, as an example you can use below code.

class Test{
    public static void main(String[] args){
        ArrayList<Integer> arraylist = new ArrayList<Integer>();

        for(int i=0; i<=10; i++){
            arraylist .add(i);
        }
       for (Integer n : arraylist ){
            System.out.println(n);
       }
   }
}

The output is above code:

{
    class Program
    {
        public static List<Product> list;
        static void Main(string[] args)
        {

            list = new List<Product>() { new Product() { ProductId=1, Name="Nike 12N0",Brand="Nike",Price=12000,Quantity=50},
                 new Product() { ProductId =2, Name = "Puma 560K", Brand = "Puma", Price = 120000, Quantity = 55 },
                 new Product() { ProductId=3, Name="WoodLand V2",Brand="WoodLand",Price=21020,Quantity=25},
                 new Product() { ProductId=4, Name="Adidas S52",Brand="Adidas",Price=20000,Quantity=35},
                 new Product() { ProductId=5, Name="Rebook SPEED2O",Brand="Rebook",Price=1200,Quantity=15}};


            Console.WriteLine("Enter ProductID to remove");
            int uno = Convert.ToInt32(Console.ReadLine());
            var itemToRemove = list.Find(r => r.ProductId == uno);
            if (itemToRemove != null)
                list.Remove(itemToRemove);
            Console.WriteLine($"{itemToRemove.ProductId}{itemToRemove.Name}{itemToRemove.Brand}{itemToRemove.Price}{ itemToRemove.Quantity}");
            Console.WriteLine("------------sucessfully Removed---------------");

            var query2 = from x in list select x;
            foreach (var item in query2)
            {
                /*Console.WriteLine(item.ProductId+" "+item.Name+" "+item.Brand+" "+item.Price+" "+item.Quantity );*/
                Console.WriteLine($"{item.ProductId}{item.Name}{item.Brand}{item.Price}{ item.Quantity}");
            }

        }

    }
}

Use Range("A1").Text instead of .Value

post comment edit:
Why?
Because the .Text property of Range object returns what is literally visible in the spreadsheet, so if you cell displays for example i100l:25he*_92 then <- Text will return exactly what it in the cell including any formatting.
The .Value and .Value2 properties return what's stored in the cell under the hood excluding formatting. Specially .Value2 for date types, it will return the decimal representation.

If you want to dig deeper into the meaning and performance, I just found this article which seems like a good guide

another edit
Here you go @Santosh
type in (MANUALLY) the values from the DEFAULT (col A) to other columns
Do not format column A at all
Format column B as Text
Format column C as Date[dd/mm/yyyy]
Format column D as Percentage

now,
paste this code in a module

Sub main()

    Dim ws As Worksheet, i&, j&
    Set ws = Sheets(1)
    For i = 3 To 7
        For j = 1 To 4
            Debug.Print _
                    "row " & i & vbTab & vbTab & _
                    Cells(i, j).Text & vbTab & _
                    Cells(i, j).Value & vbTab & _
                    Cells(i, j).Value2
        Next j
    Next i
End Sub

and Analyse the output! Its really easy and there isn't much more i can do to help :)

You can use sort.Slice() plus sort.Search()

type Person struct {
    Name string
}

func main() {
    crowd := []Person{{"Zoey"}, {"Anna"}, {"Benni"}, {"Chris"}}

    sort.Slice(crowd, func(i, j int) bool {
        return crowd[i].Name <= crowd[j].Name
    })

    needle := "Benni"
    idx := sort.Search(len(crowd), func(i int) bool {
        return string(crowd[i].Name) >= needle
    })

    if crowd[idx].Name == needle {
        fmt.Println("Found:", idx, crowd[idx])
    } else {
        fmt.Println("Found noting: ", idx)
    }
}

No need of any java in-built functions. Simple recursion will do.

public class DecimaltoBinaryTest {
     public static void main(String[] args) {
        DecimaltoBinary decimaltoBinary = new DecimaltoBinary();
        System.out.println("hello " + decimaltoBinary.convertToBinary(1000,0));
    }

}

class DecimaltoBinary {

    public DecimaltoBinary() {
    }

    public int convertToBinary(int num,int binary) {
        if (num == 0 || num == 1) {
            return num;
        } 
        binary = convertToBinary(num / 2, binary);
        binary = binary * 10 + (num % 2);
        return binary;
    }
}

>>> a = "123"
>>> int(a)
123

Here's some freebie code:

def getTwoNumbers():
    numberA = raw_input("Enter your first number: ")
    numberB = raw_input("Enter your second number: ")
    return int(numberA), int(numberB)

As of .NET Core 2.2, TargetMigration seems to be gone:

get-help Update-Database

NAME
    Update-Database

SYNOPSIS
    Updates the database to a specified migration.


SYNTAX
    Update-Database [[-Migration] <String>] [-Context <String>] [-Project <String>] [-StartupProject <String>] [<CommonParameters>]


DESCRIPTION
    Updates the database to a specified migration.


RELATED LINKS
    Script-Migration
    about_EntityFrameworkCore 

REMARKS
    To see the examples, type: "get-help Update-Database -examples".
    For more information, type: "get-help Update-Database -detailed".
    For technical information, type: "get-help Update-Database -full".
    For online help, type: "get-help Update-Database -online"

So this works for me now:

Update-Database -Migration 20180906131107_xxxx_xxxx

As well as (no -Migration switch):

Update-Database 20180906131107_xxxx_xxxx

On an added note, you can no longer cleanly delete migration folders without putting your Model Snapshot out of sync. So if you learn this the hard way and wind up with an empty migration where you know there should be changes, you can run (no switches needed for the last migration):

Remove-migration

It will clean up the mess and put you back where you need to be, even though the last migration folder was deleted manually.

Zues77 has the right idea. The OP didn't say "how can i hack my way through this". OP wanted to know how to permanently append to $PATH:

sudo nano /etc/profile

This is where it is set for everything and is the best place to change it for all things needing $PATH

The simple answer for this one is that you have an undeclared (null) variable. In this case it is $md5. From the comment you put this needed to be declared elsewhere in your code

$md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider

The error was because you are trying to execute a method that does not exist.

PS C:\Users\Matt> $md5 | gm


   TypeName: System.Security.Cryptography.MD5CryptoServiceProvider

The .ComputeHash() of $md5.ComputeHash() was the null valued expression. Typing in gibberish would create the same effect.

PowerShell by default allows this to happen as defined its StrictMode

When Set-StrictMode is off, uninitialized variables (Version 1) are assumed to have a value of 0 (zero) or $Null, depending on type. References to non-existent properties return $Null, and the results of function syntax that is not valid vary with the error. Unnamed variables are not permitted.

SELECT id, 
       IF(type = 'P', amount, amount * -1) as amount
FROM report

See http://dev.mysql.com/doc/refman/5.0/en/control-flow-functions.html.

Additionally, you could handle when the condition is null. In the case of a null amount:

SELECT id, 
       IF(type = 'P', IFNULL(amount,0), IFNULL(amount,0) * -1) as amount
FROM report

The part IFNULL(amount,0) means when amount is not null return amount else return 0.

You have set the upstream of that branch

(see:

• "How do you make an existing git branch track a remote branch?" and
• "Git: Why do I need to do --set-upstream-to all the time?"
  )

git branch -f --track my_local_branch origin/my_remote_branch
# OR (if my_local_branch is currently checked out):
$ git branch --set-upstream-to my_local_branch origin/my_remote_branch

(git branch -f --track won't work if the branch is checked out: use the second command git branch --set-upstream-to instead, or you would get "fatal: Cannot force update the current branch.")

That means your branch is already configured with:

branch.my_local_branch.remote origin
branch.my_local_branch.merge my_remote_branch

Git already has all the necessary information.
In that case:

# if you weren't already on my_local_branch branch:
git checkout my_local_branch 
# then:
git pull

is enough.

If you hadn't establish that upstream branch relationship when it came to push your 'my_local_branch', then a simple git push -u origin my_local_branch:my_remote_branch would have been enough to push and set the upstream branch.
After that, for the subsequent pulls/pushes, git pull or git push would, again, have been enough.

The example you copied from is using data in the form of an array holding arrays, you are using data in the form of an array holding objects. Objects and arrays are not the same, and because of this they use different syntaxes for accessing data.

If you don't know the variable names, just do a var_dump($blog); within the loop to see them.

The simplest method - access $blog as an object directly:

Try (assuming those variables are correct):

<?php 
    foreach ($blogs as $blog) {
        $id         = $blog->id;
        $title      = $blog->title;
        $content    = $blog->content;
?>

<h1> <?php echo $title; ?></h1>
<h1> <?php echo $content; ?> </h1>

<?php } ?>

The alternative method - access $blog as an array:

Alternatively, you may be able to turn $blog into an array with get_object_vars (documentation):

<?php
    foreach($blogs as &$blog) {
        $blog     = get_object_vars($blog);
        $id       = $blog['id'];
        $title    = $blog['title'];
        $content  = $blog['content'];
?>

<h1> <?php echo $title; ?></h1>
<h1> <?php echo $content; ?> </h1>

<?php } ?> 

It's worth mentioning that this isn't necessarily going to work with nested objects so its viability entirely depends on the structure of your $blog object.

Better than either of the above - Inline PHP Syntax

Having said all that, if you want to use PHP in the most readable way, neither of the above are right. When using PHP intermixed with HTML, it's considered best practice by many to use PHP's alternative syntax, this would reduce your whole code from nine to four lines:

<?php foreach($blogs as $blog): ?>
    <h1><?php echo $blog->title; ?></h1>
    <p><?php echo $blog->content; ?></p>
<?php endforeach; ?>

Hope this helped.

Try creating a class named overlay and apply the following css to it:

a.overlay { width: 100%; height:100%; position: absolute; }

Make sure it is placed in a positioned element.

Now simply place an <a> tag with that class inside the div you want to be linkable:

<div id="buttonOne">
  <a class="overlay" href="......."></a>
    <div id="linkedinB">
       <img src="img/linkedinB.png" alt="never forget the alt tag" width="40" height="40"/>
    </div>
 </div>

PhilipK's suggestion might work but it won't validate because you can't place a block element (div) inside an inline element (a). And when your website doesn't validate the W3C Ninja's will come for you!

An other advice would be to try avoiding inline styling.

This answer says to use

mapfile -t myArray < file.txt

I made a shim for mapfile if you want to use mapfile on bash < 4.x for whatever reason. It uses the existing mapfile command if you are on bash >= 4.x

Currently, only options -d and -t work. But that should be enough for that command above. I've only tested on macOS. On macOS Sierra 10.12.6, the system bash is 3.2.57(1)-release. So the shim can come in handy. You can also just update your bash with homebrew, build bash yourself, etc.

It uses this technique to set variables up one call stack.

A space is legal in file names. If you put your path and file name in quotes, it may just fly. Here's what I'm using in a batch file:

svnadmin hotcopy "C:\SourcePath\Folder" "f:\DestPath\Folder%filename%"

It doesn't matter if there are spaces in %filename%.

If you are working with numbers and f(A(i,j)) = f(A(j,i)), you could use scipy.spatial.distance.cdist defining f as a distance between A(i) and A(j).

If the file is on your local domain, you don't need to put the full URL. Only the path to the file. If the file is in a different directory, then you need to preface the path with "."

$file = './images/image.jpg';
if (file_exists($file)) {}

Often times the "." is left off which will cause the file to be shown as not existing, when it in fact does.

A few things here...

If you want to call a function when the onclick event happens, you'll just want the function name plus the parameters.

Then if your parameters are a variable (which they look like they are), then you won't want quotes around them. Not only that, but if these are global variables, you'll want to add in "window." before that, because that's the object that holds all global variables.

Lastly, if these parameters aren't variables, you'll want to exclude the slashes to escape those characters. Since the value of onclick is wrapped by double quotes, single quotes won't be an issue. So your answer will look like this...

<a href=# onclick="ReAssign('valuationId', window.user)">Re-Assign</a>

There are a few extra things to note here, if you want more than a quick solution.

You looked like you were trying to use the + operator to combine strings in HTML. HTML is a scripting language, so when you're writing it, the whole thing is just a string itself. You can just skip these from now on, because it's not code your browser will be running (just a whole bunch of stuff, and anything that already exists is what has special meaning by the browser).

Next, you're using an anchor tag/link that doesn't actually take the user to another website, just runs some code. I'd use something else other than an anchor tag, with the appropriate CSS to format it to look the way you want. It really depends on the setting, but in many cases, a span tag will do. Give it a class (like class="runjs") and have a rule of CSS for that. To get it to imitate a link's behavior, use this:

.runjs {
    cursor: pointer;
    text-decoration: underline;
    color: blue;
}

This lets you leave out the href attribute which you weren't using anyways.

Last, you probably want to use JavaScript to set the value of this link's onclick attribute instead of hand writing it. It keeps your page cleaner by keeping the code of your page separate from what the structure of your page. In your class, you could change all these links like this...

var links = document.getElementsByClassName('runjs');
for(var i = 0; i < links.length; i++)
    links[i].onclick = function() { ReAssign('valuationId', window.user); };

While this won't work in some older browsers (because of the getElementsByClassName method), it's just three lines and does exactly what you're looking for. Each of these links has an anonymous function tied to them meaning they don't have any variable tied to them except that tag's onclick value. Plus if you wanted to, you could include more lines of code this way, all grouped up in one tidy location.

/^(?:[a-zA-Z0-9]+|[a-zA-Z0-9][-a-zA-Z0-9]+[a-zA-Z0-9])(?:\.[a-zA-Z0-9]+|[a-zA-Z0-9][-a-zA-Z0-9]+[a-zA-Z0-9])?$/

Try this:

SELECT SUM(transaction_amount) FROM TransactionMaster WHERE Card_No ='123' AND CONVERT(VARCHAR(10),GETDATE(),111)

The GETDATE() function returns the current date and time from the SQL Server.

Like this:

import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);

Or adding from an Array/ or multiple literals; wrap to a list, first.

Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b));         // from an array variable
b.addAll( Arrays.asList( 8, 9, 10));  // from literals

To get the intersection:

// copies all from A;  then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print;   r.toString() implied.
System.out.println("A intersect B="+r);

Hope this answer helps. Vote for it!

Do everything in the inline of UL tag

<ul class="dropdown-menu scrollable-menu" role="menu" style="height: auto;max-height: 200px; overflow-x: hidden;">
                <li><a href="#">Action</a></li>
                <li><a href="#">Another action</a></li>
                <li><a href="#">Something else here</a></li>
                <li><a href="#">Action</a></li>
                ..
                <li><a href="#">Action</a></li>
                <li><a href="#">Another action</a></li>
            </ul>

Lower Case Letters

for ($x = 97; $x < 122; $x++) {
    $y = chr($x);
    echo $y;
    echo "<br>";
}

Upper Case Letters

for ($x = 65; $x < 90; $x++) {
    $y = chr($x);
    echo $y;
    echo "<br>";
}

The current object is explicitly passed to the method as the first parameter. self is the conventional name. You can call it anything you want but it is strongly advised that you stick with this convention to avoid confusion.

You can also just add an ON CONFLICT REPLACE clause to your user_name unique constraint and then just INSERT away, leaving it to SQLite to figure out what to do in case of a conflict. See:https://sqlite.org/lang_conflict.html.

Also note the sentence regarding delete triggers: When the REPLACE conflict resolution strategy deletes rows in order to satisfy a constraint, delete triggers fire if and only if recursive triggers are enabled.

With yield you can easily describe the breakpoints between multiple tasks in a single function. That's all, there is nothing special about it.

$closure = function ($injected1, $injected2, ...){
    $returned = array();
    //task1 on $injected1
    $returned[] = $returned1;
//I need a breakpoint here!!!!!!!!!!!!!!!!!!!!!!!!!
    //task2 on $injected2
    $returned[] = $returned2;
    //...
    return $returned;
};
$returned = $closure($injected1, $injected2, ...);

If task1 and task2 are highly related, but you need a breakpoint between them to do something else:

• free memory between processing database rows
• run other tasks which provide dependency to the next task, but which are unrelated by understanding the current code
• doing async calls and wait for the results
• and so on ...

then generators are the best solution, because you don't have to split up your code into many closures or mix it with other code, or use callbacks, etc... You just use yield to add a breakpoint, and you can continue from that breakpoint if you are ready.

Add breakpoint without generators:

$closure1 = function ($injected1){
    //task1 on $injected1
    return $returned1;
};
$closure2 = function ($injected2){
    //task2 on $injected2
    return $returned1;
};
//...
$returned1 = $closure1($injected1);
//breakpoint between task1 and task2
$returned2 = $closure2($injected2);
//...

Add breakpoint with generators

$closure = function (){
    $injected1 = yield;
    //task1 on $injected1
    $injected2 = (yield($returned1));
    //task2 on $injected2
    $injected3 = (yield($returned2));
    //...
    yield($returnedN);
};
$generator = $closure();
$returned1 = $generator->send($injected1);
//breakpoint between task1 and task2
$returned2 = $generator->send($injected2);
//...
$returnedN = $generator->send($injectedN);

note: It is easy to make mistake with generators, so always write unit tests before you implement them! note2: Using generators in an infinite loop is like writing a closure which has infinite length...

Put the following code before int main():

using namespace std;

And you will be able to use cout.

For example:

#include<iostream>
using namespace std;
int main(){
    char t = 'f';
    char *t1;
    char **t2;
    cout<<t;        
    return 0;
}

Now take a moment and read up on what cout is and what is going on here: http://www.cplusplus.com/reference/iostream/cout/

Further, while its quick to do and it works, this is not exactly a good advice to simply add using namespace std; at the top of your code. For detailed correct approach, please read the answers to this related SO question.

http://www.program-transformation.org/Transform/VisualBasicDecompilers

This link provides a lot of resources for VB6 Decompiling, but it seems like it will depend greatly on what you DO have (do you still have the pre-link Object code [EDIT: er... p-code I mean], or just the EXE?) Either way, it looks like there's something, take a look in there.

When the shape is not regular or the elements have different data types, the dtype argument passed to np.array only can be object.

import numpy as np

# arr1 = np.array([[10, 20.], [30], [40]], dtype=np.float32)  # error
arr2 = np.array([[10, 20.], [30], [40]])  # OK, and the dtype is object
arr3 = np.array([[10, 20.], 'hello'])     # OK, and the dtype is also object

I just needed to make artisan executable.

chmod +x artisan

...and it works without the php prefix then.

In my case, Oracle TNS Service was using port 8080, found that using running the command "netstat - anob" as an administrator. Simply used Shutdown Database from the Windows start menu to stop that service and was able to start the SpringBoot app without any issue.

Also if you cannot find out which app is using the 8080 port and just want to run the SprintBoot app, you can click on Run As... and in the VM arguments enter: -Dserver.port=0 (this will pick any random available port) or you can be specific like: -Dserver.port=8081

Hope it helps.

use a negative character class:

[^,;]+

Temporarily changing dirs works well for importing:

cwd = os.getcwd()
os.chdir(<module_path>)
import <module>
os.chdir(cwd)

I'm not sure what you're trying to do, but here's something to consider: c(); won't do anything. c is an instance of the class checkbox and not a method to be called. So consider this:

public class FirstWindow extends JFrame {      public FirstWindow() {         checkbox c = new checkbox();         c.yourMethod(yourParameters); // call the method you made in checkbox     } }  public class checkbox extends JFrame {      public checkbox(yourParameters) {          // this is the constructor method used to initialize instance variables     }      public void yourMethod() // doesn't have to be void     {         // put your code here     } } 

Modules Preconditions:

The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (precondition="managedHandler") only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:

<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />

If you remove the attribute precondition="managedHandler", Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.

You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "managedHandler" precondition.

To enable all managed modules to run for all requests without configuring each module entry to remove the "managedHandler" precondition, use the runAllManagedModulesForAllRequests property in the <modules> section:

<modules runAllManagedModulesForAllRequests="true" />    

When you use this property, the "managedHandler" precondition has no effect and all managed modules run for all requests.

Caused by: java.io.NotSerializableException: com.resources.student_list.DSLL$DNode

Your DSLL class appears to have a DNode static inner class, and DNode is not Serializable.

Yes, you can use json_encode to take your HTML string and escape it as necessary.

Note that in JSON, the top level item must be an array or object (that's not true anymore), it cannot just be a string. So you'll want to create an object and make the HTML string a property of the object (probably the only one), so the resulting JSON looks something like:

{"html": "<p>I'm the markup</p>"}

Both are used to send some data and receive some response using that data.

GET: Get information stored in the server. (i.e. search, tweet, person information). If you want to send information then get request send request using process.php?name=subroto So it basically sends information through url. Url cannot handle more than 2036 char. So for blog post can you remember it is not possible?

POST: Post do same thing as GET. User registration, User login, Big data send, Blog Post. If you need to send secure information then use post or for big data as it not go through url.

AJAX: $.get() and $.post() contain features that are subsets of $.ajax(). It has more configuration.

$.get () method, which is a kind of shorthand for $.ajax(). When using $.get (), instead of passing in an object, you pass in arguments. At minimum, you’ll need the first two arguments, which are the URL of the file you want to retrieve (eg. test.txt) and a success callback.

RichTextBox rtf = new RichTextBox();
System.IO.MemoryStream stream = new System.IO.MemoryStream(ASCIIEncoding.Default.GetBytes(yourText));

rtf.Selection.Load(stream, DataFormats.Rtf);

OR

rtf.Selection.Text = yourText;

You should just grab the window by the title bar and snap it to the left side of your screen (close browser) then reopen the browser ans snap it to the top... problem is over.

During reversing some code (which I don't remember, few years ago) I saw single line difference between the Machine Code of :? and if-else. Don't remember much but it is clear that implementation of both is different.

But I advise You to not choose one of them b'coz of its efficiency, choose according to readability of code or your convenience. Happy Coding

Finally solved it ;). Got a strong hint here (Gandalfs answer touched a bit on it as well). The missing links was (mostly) the first of the parameters below, and to some extent that I overlooked the difference between keystores and truststores.

The self-signed server certificate must be imported into a truststore:

keytool -import -alias gridserver -file gridserver.crt -storepass $PASS -keystore gridserver.keystore

These properties need to be set (either on the commandline, or in code):

-Djavax.net.ssl.keyStoreType=pkcs12
-Djavax.net.ssl.trustStoreType=jks
-Djavax.net.ssl.keyStore=clientcertificate.p12
-Djavax.net.ssl.trustStore=gridserver.keystore
-Djavax.net.debug=ssl # very verbose debug
-Djavax.net.ssl.keyStorePassword=$PASS
-Djavax.net.ssl.trustStorePassword=$PASS

Working example code:

SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
URL url = new URL("https://gridserver:3049/cgi-bin/ls.py");
HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
conn.setSSLSocketFactory(sslsocketfactory);
InputStream inputstream = conn.getInputStream();
InputStreamReader inputstreamreader = new InputStreamReader(inputstream);
BufferedReader bufferedreader = new BufferedReader(inputstreamreader);

String string = null;
while ((string = bufferedreader.readLine()) != null) {
    System.out.println("Received " + string);
}

For me only deleting this file : easy-install.pth worked, rest pip install django==1.3.7

for sqlite, check out the firefox extension. It offers a serviceable GUI.

Based on @YackY answer shorter recursion version:

function createFormData(formData, key, data) {
    if (data === Object(data) || Array.isArray(data)) {
        for (var i in data) {
            createFormData(formData, key + '[' + i + ']', data[i]);
        }
    } else {
        formData.append(key, data);
    }
}

Usage example:

var data = {a: '1', b: 2, c: {d: '3'}};
var formData = new FormData();
createFormData(formData, 'data', data);

Sent data:

data[a]=1&
data[b]=2&
data[c][d]=3

You could insert input fields without "name" attribute:

<input type="text" id="in-between" />

Or you could simply remove them once the form is submitted (in jQuery):

$("form").submit(function() {
   $(this).children('#in-between').remove();
});

Also works on bootstrap 4.x

$('#modal_ID').modal( 'hide' ).data( 'bs.modal', null );

res = request.GET['paymentid'] will raise a KeyError if paymentid is not in the GET data.

Your sample php code checks to see if paymentid is in the POST data, and sets $payID to '' otherwise:

$payID = isset($_POST['paymentid']) ? $_POST['paymentid'] : ''

The equivalent in python is to use the get() method with a default argument:

payment_id = request.POST.get('payment_id', '')

while debugging, this is what I see in the response.GET: <QueryDict: {}>, request.POST: <QueryDict: {}>

It looks as if the problem is not accessing the POST data, but that there is no POST data. How are you are debugging? Are you using your browser, or is it the payment gateway accessing your page? It would be helpful if you shared your view.

Once you are managing to submit some post data to your page, it shouldn't be too tricky to convert the sample php to python.

I'd add, that you can also use this to call multiple emits or methods or both together by separating with ; semicolon

  @click="method1(); $emit('emit1'); $emit('emit2');"

If you want to do it in XML, jus set paddingTopand paddingLeft to your RecyclerView and equal amount of layoutMarginBottom and layoutMarginRight to the item you inflate into your RecyclerView(or vice versa).

$.each(result, function(key, value) {
  console.log(key+ ':' + value);
});

Easiest true sync solution (i.e. no yield/async) I could come up with that works in all OS's without any dependencies is to call the node process to eval an in-line setTimeout expression:

const sleep = (ms) => require("child_process")
    .execSync(`"${process.argv[0]}" -e setTimeout(function(){},${ms})`);

You need to call ResultSet#beforeFirst() to put the cursor back to before the first row before you return the ResultSet object. This way the user will be able to use next() the usual way.

resultSet.last();
rows = resultSet.getRow();
resultSet.beforeFirst();
return resultSet;

However, you have bigger problems with the code given as far. It's leaking DB resources and it is also not a proper OOP approach. Lookup the DAO pattern. Ultimately you'd like to end up as

public List<Operations> list() throws SQLException {
    // Declare Connection, Statement, ResultSet, List<Operation>.

    try {
        // Use Connection, Statement, ResultSet.

        while (resultSet.next()) {
            // Add new Operation to list.
        }
    } finally {
        // Close ResultSet, Statement, Connection.
    }

    return list;
}

This way the caller has just to use List#size() to know about the number of records.

I ran into a similar issue when building a custom pagination for a site I am working on.

The global variable I created in functions.php was defined and set to 0. I could output this value in my javascript no problem using the method @Karsten outlined above. The issue was with updating the global variable that I initially set to 0 inside the PHP file.

Here is my workaround (hacky? I know!) but after struggling for an hour on a tight deadline the following works:

Inside archive-episodes.php:

<script>
    // We define the variable and update it in a php
    // function defined in functions.php
    var totalPageCount; 
</script>

Inside functions.php

<?php
    $totalPageCount = WP_Query->max_num_pages; // In my testing scenario this number is 8.
    echo '<script>totalPageCount = $totalPageCount;</script>';
?>

To keep it simple, I was outputting the totalPageCount variable in an $ajax.success callback via alert.

$.ajax({
        url: ajaxurl,
        type: 'POST',
        data: {"action": "infinite_scroll", "page_no": pageNumber, "posts_per_page": numResults},
        beforeSend: function() {
            $(".ajaxLoading").show();
        },
        success: function(data) {
                            //alert("DONE LOADING EPISODES");
            $(".ajaxLoading").hide();

            var $container = $("#episode-container");

            if(firstRun) {
                $container.prepend(data);
                initMasonry($container);
                ieMasonryFix();
                initSearch();
            } else {
                var $newItems = $(data);
                $container.append( $newItems ).isotope( 'appended', $newItems );
            }
            firstRun = false;

            addHoverState();                            
            smartResize();

            alert(totalEpiPageCount); // THIS OUTPUTS THE CORRECT PAGE TOTAL
        }

Be it as it may, I hope this helps others! If anyone has a "less-hacky" version or best-practise example I'm all ears.

The best way to do this is by running the command:

git diff --name-only --cached

When you check the manual you will likely find the following:

--name-only
    Show only names of changed files.

And on the example part of the manual:

git diff --cached
    Changes between the index and your current HEAD.

Combined together you get the changes between the index and your current HEAD and Show only names of changed files.

Update: --staged is also available as an alias for --cached above in more recent git versions.

Add this to css of your div: word-wrap: break-word;

You can use these plugins;

Just wrap all that inside a ScrollView:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
    <!-- Here you put the rest of your current view-->
</ScrollView>

As David Hedlund said, ScrollView can contain just one item... so if you had something like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
    <!-- bla bla bla-->
</LinearLayout>

You must change it to:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
    <LinearLayout
      android:layout_width="fill_parent"
      android:layout_height="fill_parent">
        <!-- bla bla bla-->
    </LinearLayout>
</ScrollView>

In regards to iterative variable names, I like making dynamic variables using Template literals. Every Tom, Dick, and Harry uses the array-style, which is fine. Until you're working with arrays and dynamic variables, oh boy! Eye-bleed overload. Since Template literals have limited support right now, eval() is even another option.

v0 = "Variable Naught";
v1 = "Variable One";

for(i = 0; i < 2; i++)
{//console.log(i) equivalent is console.log(`${i}`)
  dyV = eval(`v${i}`);
  console.log(`v${i}`); /* => v0;   v1;  */      
  console.log(dyV);  /* => Variable Naught; Variable One;  */
}

When I was hacking my way through the APIs I made this little looping snippet to see behavior depending on what was done with the Template literals compared to say, Ruby. I liked Ruby's behavior more; needing to use eval() to get the value is kind of lame when you're used to getting it automatically.

_0 = "My first variable"; //Primitive
_1 = {"key_0":"value_0"}; //Object
_2 = [{"key":"value"}]    //Array of Object(s)


for (i = 0; i < 3; i++)
{
  console.log(`_${i}`);           /*  var
                                   * =>   _0  _1  _2  */

  console.log(`"_${i}"`);         /*  var name in string  
                                   * => "_0"  "_1"  "_2"  */

  console.log(`_${i}` + `_${i}`); /*  concat var with var
                                   * => _0_0  _1_1  _2_2  */

  console.log(eval(`_${i}`));     /*  eval(var)
                                   * => My first variable
                                        Object {key_0: "value_0"}
                                        [Object]  */
}

How about doing this?

import string

def isAscii(s):
    for c in s:
        if c not in string.ascii_letters:
            return False
    return True

<?php
$conn=mysqli_connect("127.0.0.1:3306","root","","admin");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="select count('user_id') from login_user";
$result=mysqli_query($conn,$sql);
$row=mysqli_fetch_array($result);
echo "$row[0]";
mysqli_close($conn);
?>

I think who the best mix for html & Css for quick and clean mod is :

<table class="table text-center">
<thead>
        <tr>                    
        <th class="text-center">Uno</th>
        <th class="text-center">Due</th>
        <th class="text-center">Tre</th>
        <th class="text-center">Quattro</th>
    </tr>
</thead>
<tbody>
    <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
        <td>4</td>
    </tr>
</tbody>
</table>

close the <table> init tag then copy where you want :) I hope it can be useful Have a good day w stackoverflow

on shell works , sending to sdtout not , so that is one workaround, to write to stdout .

I made other approach, which is not run if sys.stdout.encoding is not define, or in others words , need export PYTHONIOENCODING=UTF-8 first to write to stdout.

import sys
if (sys.stdout.encoding is None):            
    print >> sys.stderr, "please set python env PYTHONIOENCODING=UTF-8, example: export PYTHONIOENCODING=UTF-8, when write to stdout." 
    exit(1)

so, using same example:

export PYTHONIOENCODING=UTF-8
./test.py > output.txt

will work

I had the same problem what caused it was that I already had created a pod from the docker image via the .yml file, however I mistyped the name, i.e test-app:1.0.1 when I needed test-app:1.0.2 in my .yml file. So I did kubectl delete pods --all to remove the faulty pod then redid the kubectl create -f name_of_file.yml which solved my problem.

remember, SSL/TLS operates at the Transport Layer, so all the crypto goo happens under the application-layer HTTP stuff.

that's the long way of saying, "Yes!"

Late for the answer but here are the list of things which I tried.So it will be in one place if anyone wants to try to fix the issue.

1. Valid architecture = armv7 armv7s
2. Build Active Architecture only = NO
3. Target -> Build Settings ->Other Linker Flags = $(inherited)
4. Target -> Build Settings ->Library Search Path = $(inherited)
5. Product Clean
6. Pod Update in terminal

As already stated above, the ISO-C11 preprocessor does not support string comparison. However, the problem of assigning a macro with the “opposite value” can be solved with “token pasting” and “table access”. Jesse’s simple concatenate/stringify macro-solution fails with gcc 5.4.0 because the stringization is done before the evaluation of the concatenation (conforming to ISO C11). However, it can be fixed:

#define P_(user) user ## _VS
#define VS(user) P_ (user)
#define S(U) S_(U)
#define S_(U) #U

#define jack_VS  queen
#define queen_VS jack

S (VS (jack))
S (jack)
S (VS (queen))
S (queen)

#define USER jack          // jack    or queen, your choice
#define USER_VS USER##_VS  // jack_VS or queen_VS
S (USER)
S (USER_VS)

The first line (macro P_()) adds one indirection to let the next line (macro VS()) finish the concatenation before the stringization (see Why do I need double layer of indirection for macros?). The stringization macros (S() and S_()) are from Jesse.

The table (macros jack_VS and queen_VS) which is much easier to maintain than the if-then-else construction of the OP is from Jesse.

Finally, the next four-line block invokes the function-style macros. The last four-line block is from Jesse’s answer.

Storing the code in foo.c and invoking the preprocessor gcc -nostdinc -E foo.c yields:

# 1 "foo.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "foo.c"
# 9 "foo.c"
"queen"
"jack"
"jack"
"queen"



"jack"
"USER_VS"

The output is as expected. The last line shows that the USER_VS macro is not expanded before stringization.

There a small difference when u use rgba(255,255,255,a),background color becomes more and more lighter as the value of 'a' increase from 0.0 to 1.0. Where as when use rgba(0,0,0,a), the background color becomes more and more darker as the value of 'a' increases from 0.0 to 1.0. Having said that, its clear that both (255,255,255,0) and (0,0,0,0) make background transparent. (255,255,255,1) would make the background completely white where as (0,0,0,1) would make background completely black.

You can't: It's a security feature in all modern browsers.

For IE8, it's off by default, but can be reactivated using a security setting:

When a file is selected by using the input type=file object, the value of the value property depends on the value of the "Include local directory path when uploading files to a server" security setting for the security zone used to display the Web page containing the input object.

The fully qualified filename of the selected file is returned only when this setting is enabled. When the setting is disabled, Internet Explorer 8 replaces the local drive and directory path with the string C:\fakepath\ in order to prevent inappropriate information disclosure.

In all other current mainstream browsers I know of, it is also turned off. The file name is the best you can get.

More detailed info and good links in this question. It refers to getting the value server-side, but the issue is the same in JavaScript before the form's submission.

Start with a basic square and borders. Each border will be given a different color so we can tell them apart:

.triangle {
    border-color: yellow blue red green;
    border-style: solid;
    border-width: 200px 200px 200px 200px;
    height: 0px;
    width: 0px;
}

<div class="triangle"></div>

which gives you this:

But there's no need for the top border, so set its width to 0px. Now our border-bottom of 200px will make our triangle 200px tall.

.triangle {
    border-color: yellow blue red green;
    border-style: solid;
    border-width: 0px 200px 200px 200px;
    height: 0px;
    width: 0px;
}

<div class="triangle"></div>

and we will get this:

Then to hide the two side triangles, set the border-color to transparent. Since the top-border has been effectively deleted, we can set the border-top-color to transparent as well.

.triangle {
    border-color: transparent transparent red transparent;
    border-style: solid;
    border-width: 0px 200px 200px 200px;
    height: 0px;
    width: 0px;
}

<div class="triangle"></div>

finally we get this:

A promisified version of the most-awarded answer:

  runCmd: (cmd, args) => {
    return new Promise((resolve, reject) => {
      var spawn = require('child_process').spawn
      var child = spawn(cmd, args)
      var resp = ''
      child.stdout.on('data', function (buffer) { resp += buffer.toString() })
      child.stdout.on('end', function () { resolve(resp) })
    })
  }

To use:

 runCmd('ls').then(ret => console.log(ret))

In case you're using SharePoint 2010, using the following line of code will avoid having to reference the whole System.Web library:

Microsoft.SharePoint.Utilities.SPHttpUtility.HtmlEncode(stringToEncode);

Step 1: setAdapter to your listview.

 listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice, GENRES)); 

Step 2: set choice mode for listview .The second line of below code represents which checkbox should be checked.

listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setItemChecked(2, true);

listView.setOnItemClickListener(this);



 private static  String[] GENRES = new String[] {
        "Action", "Adventure", "Animation", "Children", "Comedy", "Documentary", "Drama",
        "Foreign", "History", "Independent", "Romance", "Sci-Fi", "Television", "Thriller"
    };

Step 3: Checked views are returned in SparseBooleanArray, so you might use the below code to get key or values.The below sample are simply displayed selected names in a single String.

@Override
    public void onItemClick(AdapterView<?> adapter, View arg1, int arg2, long arg3)
    {

    SparseBooleanArray sp=getListView().getCheckedItemPositions();

    String str="";
    for(int i=0;i<sp.size();i++)
    {
        str+=GENRES[sp.keyAt(i)]+",";
    }
    Toast.makeText(this, ""+str, Toast.LENGTH_SHORT).show();

    }

multi-disciplinary will not be hyphenated, as explained by kennytm. But multi-\-disciplinary has the same hyphenation opportunities that multidisciplinary has.

I admit that I don't know why this works. It is different from the behaviour described here (emphasis mine):

The command \- inserts a discretionary hyphen into a word. This also becomes the only point where hyphenation is allowed in this word.

Here's one RegExp that does the trick.

'good_luck_buddy' . split(/^.*?_/)[1] 

First it forces the match to start from the start with the '^'. Then it matches any number of characters which are not '_', in other words all characters before the first '_'.

The '?' means a minimal number of chars that make the whole pattern match are matched by the '.*?' because it is followed by '_', which is then included in the match as its last character.

Therefore this split() uses such a matching part as its 'splitter' and removes it from the results. So it removes everything up till and including the first '_' and gives you the rest as the 2nd element of the result. The first element is "" representing the part before the matched part. It is "" because the match starts from the beginning.

There are other RegExps that work as well like /_(.*)/ given by Chandu in a previous answer.

The /^.*?_/ has the benefit that you can understand what it does without having to know about the special role capturing groups play with replace().

Try this?

$scope.$on('$viewContentLoaded', function() {
    //call it here
});

Whenever you have to perform some action on the click of the Spinner in Android, use the following method.

mspUserState.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            doWhatIsRequired();
        }
        return false;
    }
});

One thing to keep in mind is always to return False while using the above method. If you will return True then the dropdown items of the spinner will not be displayed on clicking the Spinner.

For me the answer by @jmetz didn't work, however using pandas isnull() did.

x = x[~pd.isnull(x)]

do it using jQuery put inside code on the <head></head> tag

<script type="text/javascript">
$(document).ready(function() { 
    var docHeight = $(window).height();
    var footerHeight = $('#footer').height();
    var footerTop = $('#footer').position().top + footerHeight;  
    if (footerTop < docHeight) {
        $('#footer').css('margin-top', 10 + (docHeight - footerTop) + 'px');
    }
});
</script>

string str = Console.ReadLine(); //Reads a character from console
double a = double.Parse(str); //Converts str into the type double
double b = a * Math.PI; // Multiplies by PI
Console.WriteLine("{0}", b); // Writes the number to console

Console.Read() reads a string from console A SINGLE CHARACTER AT A TIME (but waits for an enter before going on. You normally use it in a while cycle). So if you write 25 + Enter, it will return the unicode value of 2 that is 50. If you redo a second Console.Read() it will return immediately with 53 (the unicode value of 5). A third and a fourth Console.Read() will return the end of line/carriage characters. A fifth will wait for new input.

Console.ReadLine() reads a string (so then you need to change the string to a double)

This is happen due to the id(auto increment filed missing). If you edit it in a text editor by adding a comma for the ID field this will be solved.

You can also supply the log-opts parameters on the docker run command line, like this:

docker run --log-opt max-size=10m --log-opt max-file=5 my-app:latest

or in a docker-compose.yml like this

my-app:
image: my-app:latest
logging:
    driver: "json-file"
    options:
        max-file: "5"
        max-size: 10m

The other answers are all valid, however, if you are still having a problem you might not have your class inside the src folder in which case Eclipse may not see it as part of the project. This would also invoke the same error message you have seen.

$splitPos = strpos($url, "?/");
if ($splitPos !== false) {
    $url = substr($url, 0, $splitPos) . "?" . substr($url, $splitPos + 2);
}

Initially I was just trying the method:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section

but after using this along with:

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section

problem was solved. Sample Program-

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
{
    return 30.0f;
}

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    UIView *sampleView = [[UIView alloc] init];
    sampleView.frame = CGRectMake(SCREEN_WIDTH/2, 5, 60, 4);
    sampleView.backgroundColor = [UIColor blackColor];
    return sampleView;
}

and include UITableViewDelegate protocol.

@interface TestViewController : UIViewController <UITableViewDelegate>

I don't know what happened with my project but it referenced the wrong path to the DLL. Nuget installed it properly and it was indeed on my file system along with the other packages but just referenced incorrectly.

The packages folder exists two directories up from my project and it was only going up one by starting the path with ..\packages\. I changed the path to start with ..\..\packages\ and it fixed my problem.

Yes, you can. The ability to compare values to zeros implicitly has been inherited from C, and is there in all versions of C++. You can also use if (!pointer) to check pointers for NULL.

import groovyx.net.http.HTTPBuilder;

public class HttpclassgetrRoles {
     static void main(String[] args){
         def baseUrl = new URL('http://test.city.com/api/Cirtxyz/GetUser')

         HttpURLConnection connection = (HttpURLConnection) baseUrl.openConnection();
         connection.addRequestProperty("Accept", "application/json")
         connection.with {
           doOutput = true
           requestMethod = 'GET'
           println content.text
         }

     }
}

Try adding constants to a static class. You don't end up with a Type, but you will have readable, organised constants:

public static class GroupTypes {

    public const string TheGroup = "OEM";
    public const string TheOtherGroup = "CMB";

}

First, you should define "doesn't work".
Second, I assume that your table field 'content' is varchar/text, so you need to enclose it in quotes. content = '{$content}'
And last but not least: use echo mysql_error() directly after a query to debug.

Solution on windows : restarted docker

On windows I used --use-container option during sam build

So, in order to fix stuck process, I've restarted docker

Restore ownership of the user's npm related folders, to the current user, like this:

sudo chown -R $USER:$GROUP ~/.npm
sudo chown -R $USER:$GROUP ~/.config

The easiest way to tweak this in my opinion (imho) is to edit the .git/config file in your repository. Look for the entry you messed up and just tweak the URL.

On my machine in a repo I regularly use it looks like this:

KidA% cat .git/config 
[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
    ignorecase = true
    autocflg = true
[remote "origin"]
    url = ssh://localhost:8888/opt/local/var/git/project.git
    #url = ssh://xxx.xxx.xxx.xxx:80/opt/local/var/git/project.git
    fetch = +refs/heads/*:refs/remotes/origin/*

The line you see commented out is an alternative address for the repository that I sometimes switch to simply by changing which line is commented out.

This is the file that is getting manipulated under-the-hood when you run something like git remote rm or git remote add but in this case since its only a typo you made it might make sense to correct it this way.

Joining fails if the DataFrames have some column names in common. The simplest way around it is to include an lsuffix or rsuffix keyword like so:

restaurant_review_frame.join(restaurant_ids_dataframe, on='business_id', how='left', lsuffix="_review")

This way, the columns have distinct names. The documentation addresses this very problem.

Or, you could get around this by simply deleting the offending columns before you join. If, for example, the stars in restaurant_ids_dataframe are redundant to the stars in restaurant_review_frame, you could del restaurant_ids_dataframe['stars'].

One most important and often overlooked aspect is the %MAVEN_HOME%\bin or %M2_HOME%\bin should be the first thing in the %PATH% environment variable.

The answer was:

heroku restart -a app_name

# The -a is the same as --app

Easily aliased with alias hra='heroku restart --app '
Which you can make a permanent alias by adding it to your .bashrc or .bash_aliases file as described at: https://askubuntu.com/questions/17536/how-do-i-create-a-permanent-bash-alias and
Creating permanent executable aliases
Then you can just type hra app_name

You can restart a specific remote, e.g. "staging" with:

heroku restart -a app_name -r remote_name

Alternatively if you are in the root directory of your rails application you can just type

heroku restart

to restart that app and and you can create an easy alias for that with

alias hr='heroku restart'`

You can place these aliases in your .bashrc file or (preferred) in a .bash_aliases file which is called from .bashrc

According to the latest updates for OpenCV 3.0 and higher, you need to change the Property Identifiers as follows in the code by Mehran:

cv2.cv.CV_CAP_PROP_POS_FRAMES

to

cv2.CAP_PROP_POS_FRAMES

and same applies to cv2.CAP_PROP_POS_FRAME_COUNT.

Hope it helps.

You can also copy a cell which contains the conditional formatting and then select the range (of destination document -or page-) where you want the conditional format to be applied and select "paste special" > "paste only conditional formatting"

You can use CURL for this purpose see the example code:

$url = "your url";    
$content = json_encode("your data to be sent");

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
        array("Content-type: application/json"));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);

$json_response = curl_exec($curl);

$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

if ( $status != 201 ) {
    die("Error: call to URL $url failed with status $status, response $json_response, curl_error " . curl_error($curl) . ", curl_errno " . curl_errno($curl));
}


curl_close($curl);

$response = json_decode($json_response, true);

Understand __str__ and __repr__ intuitively and permanently distinguish them at all.

__str__ return the string disguised body of a given object for readable of eyes
__repr__ return the real flesh body of a given object (return itself) for unambiguity to identify.

See it in an example

In [30]: str(datetime.datetime.now())
Out[30]: '2017-12-07 15:41:14.002752'
Disguised in string form

As to __repr__

In [32]: datetime.datetime.now()
Out[32]: datetime.datetime(2017, 12, 7, 15, 43, 27, 297769)
Presence in real body which allows to be manipulated directly.

We can do arithmetic operation on __repr__ results conveniently.

In [33]: datetime.datetime.now()
Out[33]: datetime.datetime(2017, 12, 7, 15, 47, 9, 741521)
In [34]: datetime.datetime(2017, 12, 7, 15, 47, 9, 741521) - datetime.datetime(2
    ...: 017, 12, 7, 15, 43, 27, 297769)
Out[34]: datetime.timedelta(0, 222, 443752)

if apply the operation on __str__

In [35]: '2017-12-07 15:43:14.002752' - '2017-12-07 15:41:14.002752'
TypeError: unsupported operand type(s) for -: 'str' and 'str'

Returns nothing but error.

Another example.

In [36]: str('string_body')
Out[36]: 'string_body' # in string form

In [37]: repr('real_body')
Out[37]: "'real_body'" #its real body hide inside

Hope this help you build concrete grounds to explore more answers.

Here's a more flexible way.

let's say this is your form.

<form>
<input type='checkbox' name='user_ids[]' value='1'id='checkbox_1' />
<input type='checkbox' name='user_ids[]' value='2'id='checkbox_2' />
<input type='checkbox' name='user_ids[]' value='3'id='checkbox_3' />
<input name="confirm" type="button" value="confirm" onclick="submit_form();" />
</form>

And this is your jquery ajax below...

                // Don't get confused at this portion right here
                // cuz "var data" will get all the values that the form
                // has submitted in the $_POST. It doesn't matter if you 
                // try to pass a text or password or select form element.
                // Remember that the "form" is not a name attribute
                // of the form, but the "form element" itself that submitted
                // the current post method
                var data = $("form").serialize(); 

                $.ajax({
                    url: "link/of/your/ajax.php", // link of your "whatever" php
                    type: "POST",
                    async: true,
                    cache: false,
                    data: data, // all data will be passed here
                    success: function(data){ 
                        alert(data) // The data that is echoed from the ajax.php
                    }
                });

And in your ajax.php, you try echoing or print_r your post to see what's happening inside it. This should look like this. Only checkboxes that you checked will be returned. If you didn't checked any, it will return an error.

<?php 
    print_r($_POST); // this will be echoed back to you upon success.
    echo "This one too, will be echoed back to you";

Hope that is clear enough.

It's unfortunately not so easy to do that. If you're trying to make some sort of text user interface, you may want to look into curses. If you want to display things like you normally would in a terminal, but want input like that, then you'll have to work with termios, which unfortunately appears to be poorly documented in Python. Neither of these options are that simple, though, unfortunately. Additionally, they do not work under Windows; if you need them to work under Windows, you'll have to use PDCurses as a replacement for curses or pywin32 rather than termios.

I was able to get this working decently. It prints out the hexadecimal representation of keys you type. As I said in the comments of your question, arrows are tricky; I think you'll agree.

#!/usr/bin/env python
import sys
import termios
import contextlib


@contextlib.contextmanager
def raw_mode(file):
    old_attrs = termios.tcgetattr(file.fileno())
    new_attrs = old_attrs[:]
    new_attrs[3] = new_attrs[3] & ~(termios.ECHO | termios.ICANON)
    try:
        termios.tcsetattr(file.fileno(), termios.TCSADRAIN, new_attrs)
        yield
    finally:
        termios.tcsetattr(file.fileno(), termios.TCSADRAIN, old_attrs)


def main():
    print 'exit with ^C or ^D'
    with raw_mode(sys.stdin):
        try:
            while True:
                ch = sys.stdin.read(1)
                if not ch or ch == chr(4):
                    break
                print '%02x' % ord(ch),
        except (KeyboardInterrupt, EOFError):
            pass


if __name__ == '__main__':
    main()

for specific requirement the following will work for search:

select * from table_name where (column_name1='%var1%' or column_name2='var2' or column_name='%var3%') and column_name='var';

if you want to query for searching data from the database this will work perfectly.

Hope this one will meets your need. Supply the string to process as input and supply the words which should be bold/colored as input.

func attributedString(parentString:String, arrayOfStringToProcess:[String], color:UIColor) -> NSAttributedString
{
    let parentAttributedString = NSMutableAttributedString(string:parentString, attributes:nil)
    let parentStringWords = parentAttributedString.string.components(separatedBy: " ")
    if parentStringWords.count != 0
    {
        let wordSearchArray = arrayOfStringToProcess.filter { inputArrayIndex in
            parentStringWords.contains(where: { $0 == inputArrayIndex }
            )}
        for eachWord in wordSearchArray
        {
            parentString.enumerateSubstrings(in: parentString.startIndex..<parentString.endIndex, options: .byWords)
            {
                (substring, substringRange, _, _) in
                if substring == eachWord
                {
                    parentAttributedString.addAttribute(.font, value: UIFont.boldSystemFont(ofSize: 15), range: NSRange(substringRange, in: parentString))
                    parentAttributedString.addAttribute(.foregroundColor, value: color, range: NSRange(substringRange, in: parentString))
                }
            }
        }
    }
    return parentAttributedString
}

Thank you. Happy Coding.

In C++:

#include <limits>

then use

int imin = std::numeric_limits<int>::min(); // minimum value
int imax = std::numeric_limits<int>::max();

std::numeric_limits is a template type which can be instantiated with other types:

float fmin = std::numeric_limits<float>::min(); // minimum positive value
float fmax = std::numeric_limits<float>::max();

In C:

#include <limits.h>

then use

int imin = INT_MIN; // minimum value
int imax = INT_MAX;

or

#include <float.h>

float fmin = FLT_MIN;  // minimum positive value
double dmin = DBL_MIN; // minimum positive value

float fmax = FLT_MAX;
double dmax = DBL_MAX;

You need to store the psftp script (lines from open to bye) into a separate file and pass that to psftp using -b switch:

cd "C:\Program Files (x86)\PuTTY"
psftp -b "C:\path\to\script\script.txt"

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-option-b

EDIT: For username+password: As you cannot use psftp commands in a batch file, for the same reason, you cannot specify the username and the password as psftp commands. These are inputs to the open command. While you can specify the username with the open command (open <user>@<IP>), you cannot specify the password this way. This can be done on a psftp command line only. Then it's probably cleaner to do all on the command-line:

cd "C:\Program Files (x86)\PuTTY"
psftp -b script.txt <user>@<IP> -pw <PW>

And remove the open, <user> and <PW> lines from your script.txt.

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-starting
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-pw

What you are doing atm is that you run psftp without any parameter or commands. Once you exit it (like by typing bye), your batch file continues trying to run open command (and others), what Windows shell obviously does not understand.

If you really want to keep everything in one file (the batch file), you can write commands to psftp standard input, like:

(
    echo cd ...
    echo lcd ...
    echo put log.sh
) | psftp -b script.txt <user>@<IP> -pw <PW>

There is no difference between them.

If you don't specify a value for any of the half-dozen properties that background is a shorthand for, then it is set to its default value. none and transparent are the defaults.

One explicitly sets the background-image to none and implicitly sets the background-color to transparent. The other is the other way around.

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

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

arr = new int[cols*rows];

If you either don't mind syntax

arr[row * cols + col] = Aij;

or use operator[] overaloading somewhere. This may be more cache-friendly than array of arrays, or may be not, more probably you shouldn't care about it. I just want to point out that a) array of arrays is not only solution, b) some operations are more easier to implement if matrix located in one block of memory. E.g.

for(int i=0;i < rows*cols;++i)
   matrix[i]=someOtherMatrix[i];

one line shorter than

for(int r=0;i < rows;++r)
  for(int c=0;i < cols;++s)
     matrix[r][c]=someOtherMatrix[r][c];

though adding rows to such matrix is more painful

my problem (git on macOS) was solved by using sudo git instead of just git in all add and commit commands

If you have a bunch of chars and want to concat them into a string, why not do

System.out.println("" + char1 + char2 + char3); 

?

Use the PasteSpecial method:

sht.Columns("A:G").Copy
Range("A1").PasteSpecial Paste:=xlPasteValues

BUT your big problem is that you're changing your ActiveSheet to "Data" and not changing it back. You don't need to do the Activate and Select, as per my code (this assumes your button is on the sheet you want to copy to).

In order to get a Date (that can be used in JPA later on), I did

Date startOfMonth = Date.from(LocalDate.now().withDayOfMonth(1).atStartOfDay().toInstant(ZoneOffset.UTC));

• I take current date LocalDate.now()
• Move it to first day of the month withDayOfMonth(1)
• Move it to the sart of the day atStartOfDay() to get rid of hours and minutes
• and deal with the TimeZone issues by changing it into an Instant with the "right" ZoneOffset.

To add to @BrianBeech's answer, this is even more trimmed down in java 8:

jdbcTemplate.query("select string1,string2 from table where x=1", (ResultSet rs) -> {
    HashMap<String,String> results = new HashMap<>();
    while (rs.next()) {
        results.put(rs.getString("string1"), rs.getString("string2"));
    }
    return results;
});

I'm new to AngularJS and I came across this CORS problem, almost lost my mind! Luckily i found a way to fix this. So here it goes....

My problem was, when I use AngularJS $resource in sending API requests I'm getting this error message XMLHttpRequest cannot load http://website.com. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost' is therefore not allowed access. Yup, I already added callback="JSON_CALLBACK" and it didn't work.

What I did to fix it the problem, instead of using GET method or resorting to $http.get, I've used JSONP. Just replace GET method with JSONP and change the api response format to JSONP as well.

    myApp.factory('myFactory', ['$resource', function($resource) {

           return $resource( 'http://website.com/api/:apiMethod',
                        { callback: "JSON_CALLBACK", format:'jsonp' }, 
                        { 
                            method1: { 
                                method: 'JSONP', 
                                params: { 
                                            apiMethod: 'hello world'
                                        } 
                            },
                            method2: { 
                                method: 'JSONP', 
                                params: { 
                                            apiMethod: 'hey ho!'
                                        } 
                            }
            } );

    }]);

I hope someone find this helpful. :)

There are a few examples here

It's based off this answer, but I added one to the list to make a design that is even more minimal

select.moreMinimal {

    background-color: inherit;
    display: inline-block;
    font: inherit;
    padding: 0 2.2em 0 1em;    
    margin: 0;      
    cursor: pointer;

    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    -webkit-appearance: none;
    -moz-appearance: none;
  }

select.moreMinimal {
    background-image:
      linear-gradient(45deg, transparent 50%, gray 50%),
      linear-gradient(135deg, gray 50%, transparent 50%);
    background-position:
      calc(100% - 20px), 
      calc(100% - 15px);
    background-size:
      5px 5px,
      5px 5px;
    background-repeat: no-repeat;
}
  
//TODO: Probably shouldn't be focus, cause when you click it again it's still green
select.moreMinimal:focus {
    background-image:
        linear-gradient(45deg, green 50%, transparent 50%),
        linear-gradient(135deg, transparent 50%, green 50%);
    background-position:
        calc(100% - 15px),
        calc(100% - 20px);
    background-size:
        5px 5px,
        5px 5px;
    background-repeat: no-repeat;
    border-color: green;
    outline: 0;
}

The answer is to place the root dir to the location directives:

root   /srv/www/ducklington.org/public_html;

^ is binary (as in base-2) xor, not exponentiation (which is not available as a Java operator). For exponentiation, see java.lang.Math.pow().

Despite Daniel Böhmer's working solution, Ohad Schneider offered a better solution in a comment:

If the file is usually ignored, and you force adding it - it can be accidentally ignored again in the future (like when the file is deleted, then a commit is made and the file is re-created.

You should just un-ignore it in the .gitignore file like that: Unignore subdirectories of ignored directories in Git

To check if a directory exists you can use a simple if structure like this:

if [ -d directory/path to a directory ] ; then
# Things to do

else #if needed #also: elif [new condition]
# Things to do
fi

You can also do it in the negative:

if [ ! -d directory/path to a directory ] ; then
# Things to do when not an existing directory

Note: Be careful. Leave empty spaces on either side of both opening and closing braces.

With the same syntax you can use:

-e: any kind of archive

-f: file

-h: symbolic link

-r: readable file

-w: writable file

-x: executable file

-s: file size greater than zero

As Marcus reminds, docker is basically process isolation. Starting with docker 1.8, you can copy files both ways between the host and the container, see the doc of docker cp

https://docs.docker.com/reference/commandline/cp/

Once a file is copied, you can run it locally

This is what I'm doing in TypeScript I have a little utils library where I put things like this

export const arrayToHash = (array: any[], id: string = 'id') => 
         array.reduce((obj, item) =>  (obj[item[id]] = item , obj), {})

usage:

const hash = arrayToHash([{id:1,data:'data'},{id:2,data:'data'}])

or if you have a identifier other than 'id'

const hash = arrayToHash([{key:1,data:'data'},{key:2,data:'data'}], 'key')

If you want the latest file in the directory and you are using only the LastWriteTime to determine the latest file, you can do something like below:

gci path | sort LastWriteTime | select -last 1

On the other hand, if you want to only rely on the names that have the dates in them, you should be able to something similar

gci path | select -last 1

Also, if there are directories in the directory, you might want to add a ?{-not $_.PsIsContainer}

Until all modern browsers will start support css-selector :focus-visible,
the simplest and possibly best way to save accessibility is to remove this tricky focus only for mouse users and to save it for keyboard users:

1.Use this tiny polyfill (about 10kb): https://github.com/WICG/focus-visible
2.Add next code somewhere in your css:

.js-focus-visible :focus:not(.focus-visible) {
  outline: none;
}

Browser-support of css4-selector :focus-visible right now very weak:
https://caniuse.com/#search=focus-visible

When MySQL driver is used you have to set connection param rewriteBatchedStatements to true ( jdbc:mysql://localhost:3306/TestDB?**rewriteBatchedStatements=true**).

With this param the statement is rewritten to bulk insert when table is locked only once and indexes are updated only once. So it is much faster.

Without this param only advantage is cleaner source code.

I think this is bit round-about explanation but still it clarifies using real life example.

Small Example:

Let's say playing an audio involves three steps:

1. Getting the compressed song from harddisk
2. Decompress the audio.
3. Play the uncompressed audio.

If your audio player does step 1,2,3 sequentially for every song then it is synchronous. You will have to wait for some time to hear the song till the song actually gets fetched and decompressed.

If your audio player does step 1,2,3 independent of each other, then it is asynchronous. ie. While playing audio 1 ( step 3), if it fetches audio 3 from harddisk in parallel (step 1) and it decompresses the audio 2 in parallel. (step 2 ) You will end up in hearing the song without waiting much for fetch and decompress.

As of 18/04/2017, no simple black or white list of characters and filenames is evident among the answers to this topic - and there are many replies.

The best suggestion I could come up with was to let the user name the file however he likes. Using an error handler when the application tries to save the file, catch any exceptions, assume the filename is to blame (obviously after making sure the save path was ok as well), and prompt the user for a new file name. For best results, place this checking procedure within a loop that continues until either the user gets it right or gives up. Worked best for me (at least in VBA).

You can do assignments within if statements in Java as well. A good example would be reading something in and writing it out:

http://www.exampledepot.com/egs/java.io/CopyFile.html?l=new

The code:

// Copies src file to dst file.
// If the dst file does not exist, it is created
void copy(File src, File dst) throws IOException 
{
    InputStream in = new FileInputStream(src);
    OutputStream out = new FileOutputStream(dst);

    // Transfer bytes from in to out
    byte[] buf = new byte[1024];
    int len;
    while ((len = in.read(buf)) > 0) {
        out.write(buf, 0, len);
    }
    in.close();
    out.close();
}

In Xcode 6 you can do this in the storyboard:

Solution for me without reinstalling or creating a new project:

Step 1: Change line in build.gradle from:

dependencies {
    classpath 'com.android.tools.build:gradle:0.4'
}

to

dependencies {
    classpath 'com.android.tools.build:gradle:0.5.+'
}

Note: for newer versions of gradle you may need to change it to 0.6.+ instead.

Step 2: In the <YourProject>.iml file, delete the entire<component name="FacetManager">[...]</component> tag.

Step 3 (Maybe not necessary): In the Android SDK manager, install (if not already installed) Android Support Repository under Extras.

Info found here

you can delete the corresponding failed artifact directory in you local repository. And also you can simply use the -U in the goal. It will do the work. This works with maven 3. So no need to downgrade to maven 2.

In the Visual Studio solution tree, right click on the project 'UnitTest1', and then Add ? Existing item ? choose the file ../MyProjectTest/function.cpp.

Try these 4 statements..

As per the point recalled by Fred, it is not recommended to append a String with += operator since every time a new char is appended to the existing String creating a new String object again and assigning its address to st while the old st object becomes garbage.

public String convertStreamToString(InputStream is)
{
    int k;
    StringBuffer sb=new StringBuffer();
    while((k=fin.read()) != -1)
    {
        sb.append((char)k);
    }
    return sb.toString();
}

Not recommended, but this is also a way

public String convertStreamToString(InputStream is) { 
    int k;
    String st="";
    while((k=is.read()) != -1)
    {
        st+=(char)k;
    }
    return st;
}

The finite repetition syntax uses {m,n} in place of star/plus/question mark.

From java.util.regex.Pattern:

X{n}      X, exactly n times
X{n,}     X, at least n times
X{n,m}    X, at least n but not more than m times

All repetition metacharacter have the same precedence, so just like you may need grouping for *, +, and ?, you may also for {n,m}.

• ha* matches e.g. "haaaaaaaa"
• ha{3} matches only "haaa"
• (ha)* matches e.g. "hahahahaha"
• (ha){3} matches only "hahaha"

Also, just like *, +, and ?, you can add the ? and + reluctant and possessive repetition modifiers respectively.

    System.out.println(
        "xxxxx".replaceAll("x{2,3}", "[x]")
    ); "[x][x]"

    System.out.println(
        "xxxxx".replaceAll("x{2,3}?", "[x]")
    ); "[x][x]x"

Essentially anywhere a * is a repetition metacharacter for "zero-or-more", you can use {...} repetition construct. Note that it's not true the other way around: you can use finite repetition in a lookbehind, but you can't use * because Java doesn't officially support infinite-length lookbehind.

Also, Given a DataFrame

data

as in your example, if you would like to extract column a and d only (e.i. the 1st and the 4th column), iloc mothod from the pandas dataframe is what you need and could be used very effectively. All you need to know is the index of the columns you would like to extract. For example:

>>> data.iloc[:,[0,3]]

will give you

          a         d
0  0.883283  0.100975
1  0.614313  0.221731
2  0.438963  0.224361
3  0.466078  0.703347
4  0.955285  0.114033
5  0.268443  0.416996

Most shortest code:

strs = {'HA' 'KU' 'LA' 'MA' 'TATA'};
[~,ind]=ismember('KU', strs)

But it returns only first position in strs. If element not found then ind=0.
