Here is an example that works:

MatchPassword(AC: FormControl) {
  let dataForm = AC.parent;
  if(!dataForm) return null;

  var newPasswordRepeat = dataForm.get('newPasswordRepeat');
  let password = dataForm.get('newPassword').value;
  let confirmPassword = newPasswordRepeat.value;

  if(password != confirmPassword) {
    /* for newPasswordRepeat from current field "newPassword" */
    dataForm.controls["newPasswordRepeat"].setErrors( {MatchPassword: true} );
    if( newPasswordRepeat == AC ) {
      /* for current field "newPasswordRepeat" */
      return {newPasswordRepeat: {MatchPassword: true} };
    }
  } else {
    dataForm.controls["newPasswordRepeat"].setErrors( null );
  }
  return null;
}

createForm() {
  this.dataForm = this.fb.group({
    password: [ "", Validators.required ],
    newPassword: [ "", [ Validators.required, Validators.minLength(6), this.MatchPassword] ],
    newPasswordRepeat: [ "", [Validators.required, this.MatchPassword] ]
  });
}

You are adding the formControlName to the label and not the input.

You have this:

<div >
  <div class="input-field col s12">
    <input id="email" type="email"> 
    <label class="center-align" for="email" formControlName="email">Email</label>
  </div>
</div>

Try using this:

<div >
  <div class="input-field col s12">
    <input id="email" type="email" formControlName="email"> 
    <label class="center-align" for="email">Email</label>
  </div>
</div>

Update the other input fields as well.

I've come to this same question over & over again, also due to same reason. So let me answer this by saying what wrong I was doing. Might be helpful for someone.

I was creating component via angular-cli by command

ng g c components/something/something

What it did, was created the component as I wanted.

Also, While creating the component, it added the component in the App Module's declarations array.

If this is the case, please remove it. And Voila! It might work.

Here's what worked for me. Note: Adding the image within a row introduces some space so I've intentionally used only a div to encapsulate the image.

<div class="container-fluid w-100 h-auto m-0 p-0">  

    <img src="someimg.jpg" class="img-fluid w-100 h-auto p-0 m-0" alt="Patience">           

</div>

Update in July 2020:

During the last 16 months, maybe the most notable change in the React community is React hooks.

According to what I observe, in order to gain better compatibility with functional components and hooks, projects (even those large ones) would tend to use:

1. hook + async thunk (hook makes everything very flexible so you could actually place async thunk in where you want and use it as normal functions, for example, still write thunk in action.ts and then useDispatch() to trigger the thunk: https://stackoverflow.com/a/59991104/5256695),
2. useRequest,
3. GraphQL/Apollo useQuery useMutation
4. react-fetching-library
5. other popular choices of data fetching/API call libraries, tools, design patterns, etc

In comparison, redux-saga doesn't really provide significant benefit in most normal cases of API calls comparing to the above approaches for now, while increasing project complexity by introducing many saga files/generators (also because the last release v1.1.1 of redux-saga was on 18 Sep 2019, which was a long time ago).

But still, redux-saga provides some unique features such as racing effect and parallel requests. Therefore, if you need these special functionalities, redux-saga is still a good choice.

Original post in March 2019:

Just some personal experience:

1. For coding style and readability, one of the most significant advantages of using redux-saga in the past is to avoid callback hell in redux-thunk — one does not need to use many nesting then/catch anymore. But now with the popularity of async/await thunk, one could also write async code in sync style when using redux-thunk, which may be regarded as an improvement in redux-thunk.

2. One may need to write much more boilerplate codes when using redux-saga, especially in Typescript. For example, if one wants to implement a fetch async function, the data and error handling could be directly performed in one thunk unit in action.js with one single FETCH action. But in redux-saga, one may need to define FETCH_START, FETCH_SUCCESS and FETCH_FAILURE actions and all their related type-checks, because one of the features in redux-saga is to use this kind of rich “token” mechanism to create effects and instruct redux store for easy testing. Of course one could write a saga without using these actions, but that would make it similar to a thunk.

3. In terms of the file structure, redux-saga seems to be more explicit in many cases. One could easily find an async related code in every sagas.ts, but in redux-thunk, one would need to see it in actions.

4. Easy testing may be another weighted feature in redux-saga. This is truly convenient. But one thing that needs to be clarified is that redux-saga “call” test would not perform actual API call in testing, thus one would need to specify the sample result for the steps which may be used after the API call. Therefore before writing in redux-saga, it would be better to plan a saga and its corresponding sagas.spec.ts in detail.

5. Redux-saga also provides many advanced features such as running tasks in parallel, concurrency helpers like takeLatest/takeEvery, fork/spawn, which are far more powerful than thunks.

In conclusion, personally, I would like to say: in many normal cases and small to medium size apps, go with async/await style redux-thunk. It would save you many boilerplate codes/actions/typedefs, and you would not need to switch around many different sagas.ts and maintain a specific sagas tree. But if you are developing a large app with much complex async logic and the need for features like concurrency/parallel pattern, or have a high demand for testing and maintenance (especially in test-driven development), redux-sagas would possibly save your life.

Anyway, redux-saga is not more difficult and complex than redux itself, and it does not have a so-called steep learning curve because it has well-limited core concepts and APIs. Spending a small amount of time learning redux-saga may benefit yourself one day in the future.

1) react-router > V5 useHistory hook:

If you have React >= 16.8 and functional components you can use the useHistory hook from react-router.

import React from 'react';
import { useHistory } from 'react-router-dom';

const YourComponent = () => {
    const history = useHistory();

    const handleClick = () => {
        history.push("/path/to/push");
    }

    return (
        <div>
            <button onClick={handleClick} type="button" />
        </div>
    );
}

export default YourComponent;

2) react-router > V4 withRouter HOC:

As @ambar mentioned in the comments, React-router has changed their code base since their V4. Here are the documentations - official, withRouter

import React, { Component } from 'react';
import { withRouter } from "react-router-dom";

class YourComponent extends Component {
    handleClick = () => {
        this.props.history.push("path/to/push");
    }

    render() {
        return (
            <div>
                <button onClick={this.handleClick} type="button">
            </div>
        );
    };
}

export default withRouter(YourComponent);

3) React-router < V4 with browserHistory

You can achieve this functionality using react-router BrowserHistory. Code below:

import React, { Component } from 'react';
import { browserHistory } from 'react-router';

export default class YourComponent extends Component {
    handleClick = () => {
        browserHistory.push('/login');
    };

    render() {
        return (
            <div>
                <button onClick={this.handleClick} type="button">
            </div>
        );
    };
}

4) Redux connected-react-router

If you have connected your component with redux, and have configured connected-react-router all you have to do is this.props.history.push("/new/url"); ie, you don't need withRouter HOC to inject history to the component props.

// reducers.js
import { combineReducers } from 'redux';
import { connectRouter } from 'connected-react-router';

export default (history) => combineReducers({
    router: connectRouter(history),
    ... // rest of your reducers
});


// configureStore.js
import { createBrowserHistory } from 'history';
import { applyMiddleware, compose, createStore } from 'redux';
import { routerMiddleware } from 'connected-react-router';
import createRootReducer from './reducers';
...
export const history = createBrowserHistory();

export default function configureStore(preloadedState) {
    const store = createStore(
        createRootReducer(history), // root reducer with router state
        preloadedState,
        compose(
            applyMiddleware(
                routerMiddleware(history), // for dispatching history actions
                // ... other middlewares ...
            ),
        ),
    );

    return store;
}


// set up other redux requirements like for eg. in index.js
import { Provider } from 'react-redux';
import { Route, Switch } from 'react-router';
import { ConnectedRouter } from 'connected-react-router';
import configureStore, { history } from './configureStore';
...
const store = configureStore(/* provide initial state if any */)

ReactDOM.render(
    <Provider store={store}>
        <ConnectedRouter history={history}>
            <> { /* your usual react-router v4/v5 routing */ }
                <Switch>
                    <Route exact path="/yourPath" component={YourComponent} />
                </Switch>
            </>
        </ConnectedRouter>
    </Provider>,
    document.getElementById('root')
);


// YourComponent.js
import React, { Component } from 'react';
import { connect } from 'react-redux';
...

class YourComponent extends Component {
    handleClick = () => {
        this.props.history.push("path/to/push");
    }

    render() {
        return (
          <div>
            <button onClick={this.handleClick} type="button">
          </div>
        );
      }
    };

}

export default connect(mapStateToProps = {}, mapDispatchToProps = {})(YourComponent);

Update alpha 47

As of alpha 47 the below answer (for alpha46 and below) is not longer required. Now the Http module handles automatically the errores returned. So now is as easy as follows

http
  .get('Some Url')
  .map(res => res.json())
  .subscribe(
    (data) => this.data = data,
    (err) => this.error = err); // Reach here if fails

Alpha 46 and below

You can handle the response in the map(...), before the subscribe.

http
  .get('Some Url')
  .map(res => {
    // If request fails, throw an Error that will be caught
    if(res.status < 200 || res.status >= 300) {
      throw new Error('This request has failed ' + res.status);
    } 
    // If everything went fine, return the response
    else {
      return res.json();
    }
  })
  .subscribe(
    (data) => this.data = data, // Reach here if res.status >= 200 && <= 299
    (err) => this.error = err); // Reach here if fails

Here's a plnkr with a simple example.

Note that in the next release this won't be necessary because all status codes below 200 and above 299 will throw an error automatically, so you won't have to check them by yourself. Check this commit for more info.

In 4.0 version of the .Net framework the ServicePointManager.SecurityProtocol only offered two options to set:

• Ssl3: Secure Socket Layer (SSL) 3.0 security protocol.
• Tls: Transport Layer Security (TLS) 1.0 security protocol

In the next release of the framework the SecurityProtocolType enumerator got extended with the newer Tls protocols, so if your application can use th 4.5 version you can also use:

• Tls11: Specifies the Transport Layer Security (TLS) 1.1 security protocol
• Tls12: Specifies the Transport Layer Security (TLS) 1.2 security protocol.

So if you are on .Net 4.5 change your line

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;

to

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

so that the ServicePointManager will create streams that support Tls12 connections.

Do notice that the enumeration values can be used as flags so you can combine multiple protocols with a logical OR

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | 
                                       SecurityProtocolType.Tls11 |
                                       SecurityProtocolType.Tls12;

Note
Try to keep the number of protocols you support as low as possible and up-to-date with today security standards. Ssll3 is no longer deemed secure and the usage of Tls1.0 SecurityProtocolType.Tls is in decline.

You should put the folder containing css and js files into "webapp/resources". If you've put them in "src/main/java", you must change it. It worked for me.

If you are using chrome: try open chrome with the args to disable web security like you see here:

Disable same origin policy in Chrome

NullPointerException with JSP can also happen if:

A getter returns a non-public inner class.

This code will fail if you remove Getters's access modifier or make it private or protected.

JAVA:

package com.myPackage;
public class MyClass{ 
    //: Must be public or you will get:
    //: org.apache.jasper.JasperException: 
    //: java.lang.NullPointerException
    public class Getters{
        public String 
        myProperty(){ return(my_property); }
    };;

    //: JSP EL can only access functions:
    private Getters _get;
    public  Getters  get(){ return _get; }

    private String 
    my_property;

    public MyClass(String my_property){
        super();
        this.my_property    = my_property;
        _get = new Getters();
    };;
};;

JSP

<%@ taglib uri   ="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page import="com.myPackage.MyClass" %>

    MyClass inst = new MyClass("[PROP_VALUE]");
    pageContext.setAttribute("my_inst", inst );

</body></html>

Did you try RedirectView where you can provide the contextRelative parameter?

Well my client side (a cshtml file) was using DataTables to display a grid (now using Infragistics control which are great). And once the user clicked on the row, I captured the row event and the date associated with that record in order to go back to the server and make additional server-side requests for trades, etc. And no - I DID NOT stringify it...

The DataTables def started as this (leaving lots of stuff out), and the click event is seen below where I PUSH onto my Json object :

    oTablePf = $('#pftable').dataTable({         // INIT CODE
             "aaData": PfJsonData,
             'aoColumnDefs': [                     
                { "sTitle": "Pf Id", "aTargets": [0] },
                { "sClass": "**td_nodedate**", "aTargets": [3] }
              ]
              });

   $("#pftable").delegate("tbody tr", "click", function (event) {   // ROW CLICK EVT!! 

        var rownum = $(this).index(); 
        var thisPfId = $(this).find('.td_pfid').text();  // Find Port Id and Node Date
        var thisDate = $(this).find('.td_nodedate').text();

         //INIT JSON DATA
        var nodeDatesJson = {
            "nodedatelist":[]
        };

         // omitting some code here...
         var dateArry = thisDate.split("/");
         var nodeDate = dateArry[2] + "-" + dateArry[0] + "-" + dateArry[1];

         nodeDatesJson.nodedatelist.push({ nodedate: nodeDate });

           getTradeContribs(thisPfId, nodeDatesJson);     // GET TRADE CONTRIBUTIONS 
    });

I tried these solutions but never got a conclusive result. In the end I used proper semantic markup with a fieldset. It saved having to add any width calculations and any box-sizing.

It also allows you to set the form width as you require and the inputs remain within the padding you need for your edges.

In this example I have put a border on the form and fieldset and an opaque background on the legend and fieldset so you can see how they overlap and sit with each other.

<html>
  <head>
  <style>
    form {
      width: 300px;
      margin: 0 auto;
      border: 1px solid;
    }
    fieldset {
      border: 0;
      margin: 0;
      padding: 0 20px 10px;
      border: 1px solid blue;
      background: rgba(0,0,0,.2);
    }
    legend {
      background: rgba(0,0,0,.2);
      width: 100%;
      margin: 0 -20px;
      padding: 2px 20px;
      color: $col1;
      border: 0;
    }
    input[type="email"],
    input[type="password"],
    button {
      width: 100%;
      margin: 0 0 10px;
      padding: 0 10px;
    }
    input[type="email"],
    input[type="password"] {
      line-height: 22px;
      font-size: 16px;
    }
    button {
    line-height: 26px;
    font-size: 20px;
    }
  </style>
  </head>
  <body>
  <form>
      <fieldset>
          <legend>Log in</legend>
          <p>You may need some content here, a message?</p>
          <input type="email" id="email" name="email" placeholder="Email" value=""/>
          <input type="password" id="password" name="password" placeholder="password" value=""/>
          <button type="submit">Login</button>
      </fieldset>
  </form>
  </body>
</html>

I know this is an old thread but I thought I'd also make a contribution. My solution being similar to the post already marked as an answer. Some inline JavaScript checks does the trick.

ng-click="form.$invalid ? alert('Please correct the form') : saveTask(task)"

I do it on the server side, at the begining of my init file, works like a charm and you don't have to do anything in angular or existing php code:

if ($_SERVER['REQUEST_METHOD'] == 'POST' && empty($_POST))
    $_POST = json_decode(file_get_contents('php://input'), true);

You could make two forms with 2 different actions

<form action="login.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Login">
</form>

<br />

<form action="register.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Register">
</form>

Or do this

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="login">
    <input type="submit" value="Login">
</form>

<br />

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="register">
    <input type="submit" value="Register">
</form>

Then you PHP file would work as a switch($_POST['action']) ... furthermore, they can't click on both links at the same time or make a simultaneous request, each submit is a separate request.

Your PHP would then go on with the switch logic or have different php files doing a login procedure then a registration procedure

Wrong syntax. You can't compare a Boolean to a string like "false" or "true". In your case, just test it's inverse:

if(!ValidateForm()) { ...

You could test against the constant false, but it's rather ugly and generally frowned upon:

if(ValidateForm() == false) { ...

No. You can't send headers after they were sent. Try to use hooks in wordpress

set this jquery min js

script src="http://code.jquery.com/jquery-1.10.1.min.js"

in wp-admin/admin-header.php

This will do it if you want to build the posted query without middleware:

app.post("/register/",function(req,res){
    var bodyStr = '';
    req.on("data",function(chunk){
        bodyStr += chunk.toString();
    });
    req.on("end",function(){
        res.send(bodyStr);
    });

});

That will send this to the browser

email=emailval&password1=pass1val&password2=pass2val

It's probably better to use middleware though so you don't have to write this over and over in each route.

    wp_register_script('custom-js',WP_PLUGIN_URL.'/PLUGIN_NAME/js/custom.js',array(),NULL,true);
    wp_enqueue_script('custom-js');

    $wnm_custom = array( 'template_url' => get_bloginfo('template_url') );
    wp_localize_script( 'custom-js', 'wnm_custom', $wnm_custom );

and in custom.js

alert(wnm_custom.template_url);

You can do :

document.forms["loginForm"].submit()

But this won't call the onclick action of your button, so you will need to call it by hand.

Be aware that you must use the name of your form and not the id to access it.

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

should work.

From the manual:

auth_type = 'cookie' prompts for a MySQL username and password in a friendly HTML form. This is also the only way by which one can log in to an arbitrary server (if $cfg['AllowArbitraryServer'] is enabled). Cookie is good for most installations (default in pma 3.1+), it provides security over config and allows multiple users to use the same phpMyAdmin installation. For IIS users, cookie is often easier to configure than http.

For preloading background images set with CSS, the most efficient answer i came up with was a modified version of some code I found that did not work:

$(':hidden').each(function() {
  var backgroundImage = $(this).css("background-image");
  if (backgroundImage != 'none') {
    tempImage = new Image();
    tempImage.src = backgroundImage;
  }
});

The massive benefit of this is that you don't need to update it when you bring in new background images in the future, it will find the new ones and preload them!

If you have to center your childForm, from childForm then the code will be something like this. This code is in the childForm.cs

this.Show(parent as Form);    // I received the parent object as Object type
this.CenterToParent();

If we can assume that the H1 is always going to be there, then

div h1+div {...}

but don't be afraid to specify the id of the content div:

#content h1+div {...}

That's about as good as you can get cross-browser right now without resorting to a JavaScript library like jQuery. Using h1+div ensures that only the first div after the H1 gets the style. There are alternatives, but they rely on CSS3 selectors, and thus won't work on most IE installs.

I am new to all this, but for me a simple alias worked:

alias node='env NODE_NO_READLINE=1 rlwrap nodejs'

at least for running things directly in bash and executing .js files.

Check out this gist. It has snippets for how to get the sharing count for the following services:

• Facebook
• Twitter
• Google plus
• Pinterest
• LinkedIn
• StumbledUpon

As mentioned by few users, below code can help find all the fields in a given class.

TestClass testObject= new TestClass().getClass();
Method[] methods = testObject.getMethods();
for (Method method:methods)
{
    String name=method.getName();
    if(name.startsWith("get"))
    {
        System.out.println(name.substring(3));
    }else if(name.startsWith("is"))
    {
        System.out.println(name.substring(2));
    }
}

However a more interesting approach is below:

With the help of Jackson library, I was able to find all class properties of type String/integer/double, and respective values in a Map class. (without using reflections api!)

TestClass testObject = new TestClass();
com.fasterxml.jackson.databind.ObjectMapper m = new com.fasterxml.jackson.databind.ObjectMapper();

Map<String,Object> props = m.convertValue(testObject, Map.class);

for(Map.Entry<String, Object> entry : props.entrySet()){
    if(entry.getValue() instanceof String || entry.getValue() instanceof Integer || entry.getValue() instanceof Double){
        System.out.println(entry.getKey() + "-->" + entry.getValue());
    }
}

jQuery

$(function() {
    $("td[colspan=3]").find("div").hide();
    $("tr").click(function(event) {
        var $target = $(event.target);
        $target.closest("tr").next().find("div").slideToggle();                
    });
});

    </thead>
    <tbody>

        <tr>
            <td><p>data<p></td><td>data</td><td>data</td>
        </tr>
        <tr>
            <td colspan="3">
                <div>
                    <table>
                            <tr>
                                <td>data</td><td>data</td>
                            </tr>
                    </table>
                </div>
            </td>
        </tr>
    </tbody>
</table>

This is much like a previous example above. I found when trying to implement that example that if the table row to be expanded was clicked while it was not expanded it would disappear, and it would no longer be expandable

To fix that I simply removed the ability to click the expandable element for slide up and made it so that you can only toggle using the above table row.

I also made some minor changes to HTML and corresponding jQuery.

NOTE: I would have just made a comment but am not allowed to yet therefore the long post. Just wanted to post this as it took me a bit to figure out what was happening to the disappearing table row.

And to nicely dump it into a file (on Windows at least) - Git Bash:

$ echo "`git show 60d8bdfc:src/services/LocationMonitor.java`" >> LM_60d8bdfc.java

The " quotes are needed so it preserves newlines.

You can use this javascript code to redirect after a specific time. Hope it will work.

setRedirectTime(function () 
{
   window.location.href= 'https://www.google.com'; // the redirect URL will be here

},10000); // 10 seconds

To add an image to left, right, top or bottom, you can use attributes like this:

android:drawableLeft
android:drawableRight
android:drawableTop
android:drawableBottom

The sample code is given above. You can also achieve this using relative layout.

AND and OR are just syntactic sugar for && and ||, like in JavaScript, or other C styled syntax languages.

It appears AND and OR have lower precedence than their C style equivalents.

DON'T DO THIS IN PRODUCTION

The answer given by @ravi-luthra technically works but it has some issues!

In my case, I was just trying to recover disk space. The lib/docker/overlay folder was taking 30GB of space and I only run a few containers regularly. Looks like docker has some issue with data leakage and some of the temporary data are not cleared when the container stops.

So I went ahead and deleted all the contents of lib/docker/overlay folder. After that, My docker instance became un-useable. When I tried to run or build any container, It gave me this error:

failed to create rwlayer: symlink ../04578d9f8e428b693174c6eb9a80111c907724cc22129761ce14a4c8cb4f1d7c/diff /var/lib/docker/overlay2/l/C3F33OLORAASNIYB3ZDATH2HJ7: no such file or directory

Then with some trial and error, I solved this issue by running

(WARNING: This will delete all your data inside docker volumes)

docker system prune --volumes -a

So It is not recommended to do such dirty clean ups unless you completely understand how the system works.

I had the same problem. which as resolved using these steps:

1.) Click File

2.) Select "save as"

3.) Click on drop down (Save as type)

4.) Select Excel 97-2003 Workbook

5.) Click on Save button

You could dynamically generate an array of however time you wanted to render <li>Something</li>, and then do ngFor over that collection. Also you could take use of index of current element too.

Markup

<ul>
   <li *ngFor="let item of createRange(5); let currentElementIndex=index+1">
      {{currentElementIndex}} Something
   </li>
</ul>

Code

createRange(number){
  var items: number[] = [];
  for(var i = 1; i <= number; i++){
     items.push(i);
  }
  return items;
}

Demo Here

Under the hood angular de-sugared this *ngFor syntax to ng-template version.

<ul>
    <ng-template ngFor let-item [ngForOf]="createRange(5)" let-currentElementIndex="(index + 1)" [ngForTrackBy]="trackByFn">
      {{currentElementIndex}} Something
    </ng-template>
</ul>

The expires and add_header directives have no impact on NGINX caching the files, those are purely about what the browser sees.

What you likely want instead is:

location stuffyoudontwanttocache {
    # don't cache it
    proxy_no_cache 1;
    # even if cached, don't try to use it
    proxy_cache_bypass 1; 
}

Though usually .js etc is the thing you would cache, so perhaps you should just disable caching entirely?

use this style

<style name="Theme.MyFancyTheme" parent="android:Theme.Holo">
    <item name="android:homeAsUpIndicator">@drawable/back_button_image</item>
</style>

I think the best ranking is

1.node-schedule

2.later

3.crontab

and the sample of node-schedule is below:

var schedule = require("node-schedule");
var rule = new schedule.RecurrenceRule();
//rule.minute = 40;
rule.second = 10;
var jj = schedule.scheduleJob(rule, function(){
    console.log("execute jj");
});

Maybe you can find the answer from node modules.

I written also a URL validation function base on rfc1738 and rfc3986 to check http and https urls. I try to hold this modular, so it can be better maintained and adapted to own requirements.

The RegExp in one line is show at end of this post.

The RegExp accept HTTP and HTTPS URLs with some international domain or IPv4 number. IPv6 is not supported yet.

    var rg_fragment = "\\#" + "([" + rg_pchar + "/?]|" + rg_pctEncoded + ")*";

    var rgHttpUrl = new RegExp(

    // export public function
    return function (url) {
        if (rgHttpUrl.test(url)) {

HttpURLConnection has a setConnectTimeout method.

Just set the timeout to 5000 milliseconds, and then catch java.net.SocketTimeoutException

Your code should look something like this:

try {
   HttpURLConnection.setFollowRedirects(false);
   HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection();
   con.setRequestMethod("HEAD");

   con.setConnectTimeout(5000); //set timeout to 5 seconds

   return (con.getResponseCode() == HttpURLConnection.HTTP_OK);
} catch (java.net.SocketTimeoutException e) {
   return false;
} catch (java.io.IOException e) {
   return false;
}

That depends. If that definition is global (outside any function) then num will be initialized to zero. If it's local (inside a function) then its value is indeterminate. In theory, even attempting to read the value has undefined behavior -- C allows for the possibility of bits that don't contribute to the value, but have to be set in specific ways for you to even get defined results from reading the variable.

find your django parent dir path and add it to PYTHONPATH

In my case, my django parent dir path is /Library/Python/3.7/site-packages,add this line into ~/.bash_profile

export PYTHONPATH=/Library/Python/3.7/site-packages

else if you have PYTHONPATH already, just append it like this

export PYTHONPATH=${PYTHONPATH}:/Library/Python/3.7/site-packages

then

source ~/.bash_profile

You can use StringEscapeUtils from Apache Commons Logging utility or escape manually using code for each character.

The solution I use for large sql restore is a mysqldumpsplitter script. I split my sql.gz into individual tables. then load up something like mysql workbench and process it as a restore to the desired schema.

Here is the script https://github.com/kedarvj/mysqldumpsplitter

And this works for larger sql restores, my average on one site I work with is a 2.5gb sql.gz file, 20GB uncompressed, and ~100Gb once restored fully

class Graph<E> {
    private List<Vertex<E>> vertices;

    private static class Vertex<E> {
        E elem;
        List<Vertex<E>> neighbors;
    }
}

You can use jquery load for that.

<script type="text/javascript">
$(document).ready(function(e) {
    $('#header').load('name.html',function(){alert('loaded')});
});
</script>

Don't forget to include jquery library befor above code.

You can directly create your own style in this way:

 input[type=button]
 { 
//Change the style as you like
 }

You can also make additions to this path with the PYTHONPATH environment variable at runtime, in addition to:

import sys
sys.path.append('/home/user/python-libs')

I used a modified version of this answer - based on my experiences adding it to VS 2010:

1. Select Tools >> External Tools in Visual Studio
2. Click Add
3. Title: I use Visual Studio Command &Prompt
   • &P Makes P a alt-shortcut key (when menu active)
   • I originally used C, but that conflicts with the existing shortcut for Customize
4. Command: C:\Windows\System32\cmd.exe
5. Arguments: \k "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\vsvars32.bat
   • /k keeps a secondary session active so the window doesn’t close on the .bat file
6. Initial Directory: I use $(ProjectDir) (from the dropdown)
7. Click OK.

Now you have command prompt access under the Tools Menu.

See also: Add command prompt to Visual C# Express 2010

paste0("data_",seq(1,3,1)) 
# makes multiple data.frame names with sequential number
rm(list=paste0("data_",seq(1,3,1))
# above code removes data_1~data_3

It will work when adding space between id and class identifier

$("#countery .save")...

for HTML5, you can use the 'prefetch'

<link rel="prefetch" href="/style.css" as="style" />

have a look at 'preload' for js.

<link rel="preload" href="used-later.js" as="script">

My favorite is to use the .Net [IO.DirectoryInfo] class, which takes care of some of the logic. I actually use this for a lot of similar scripting challenges. It has a .Create() method that creates directories that don't exist, without errors if they do.

Since this is still a two step problem, I use the foreach alias to keep it simple. For single files:

[IO.DirectoryInfo]$to |% {$_.create(); cp $from $_}

As far as your multi file/directory match, I would use RoboCopy over xcopy. Remove the "*" from your from and just use:

RoboCopy.exe $from $to *

You can still add the /r (Recurse), /e (Recurse including Empty), and there are 50 other useful switches.

Edit: Looking back at this it is terse, but not very readable if you are not using the code often. Usually I have it split into two, like so:

([IO.DirectoryInfo]$to).Create()
cp $from $to

Also, DirectoryInfo is the type of the Parent property of FileInfo, so if your $to is a file, you can use them together:

([IO.FileInfo]$to).Parent.Create()
cp $from $to

KDiff3 open source, cross platform

Same interface for Linux and Windows, very smart algorithm for solving conflicts, regular expressions for automatically solving conflicts, integrate with ClearCase, SVN, Git, MS Visual Studio, editable merged file, compare directories

Its keyboard-navigation is great: ctrl-arrows to navigate the diffs, ctrl-1, 2, 3 to do the merging.

Also, see https://stackoverflow.com/a/2434482/42473

You can use method named compareTo, x.compareTo(y). It will return 0 if x and y are equal, 1 if x is greater than y and -1 if x is smaller than y

It is an old post, but I came across this recently

Selecting a specific interval

As @aleroot already mentioned, by using

table.setRowSelectionInterval(index0, index1);

You can specify an interval, which should be selected.

Adding an interval to the existing selection

You can also keep the current selection, and simply add additional rows by using this here

table.getSelectionModel().addSelectionInterval(index0, index1);

This line of code additionally selects the specified interval. It doesn't matter if that interval already is selected, of parts of it are selected.

Starting with Bootstrap v3.3.0 you can use .media-left and .media-body

<div class="media">
    <span class="media-left">
        <img src="../site/img/success32.png" alt="...">
    </span>
    <div class="media-body">
        <h3 class="media-heading">Experience</h3>
        ...
    </div>
</div>

Make sure that the Objects in your list have equals() defined on them. Then

assertThat(generatedList, is(equalTo(expectedList)));

works.

1. Script the create table in management studio, run that script in bar to create the table. (Right click table in object explorer, script table as, create to...)

2. INSERT bar.[schema].table SELECT * FROM foo.[schema].table

I prefer minecart as it is extremely easy to use. The below snippet show how to extract images from a pdf:

#pip install minecart
import minecart

pdffile = open('Invoices.pdf', 'rb')
doc = minecart.Document(pdffile)

page = doc.get_page(0) # getting a single page

#iterating through all pages
for page in doc.iter_pages():
    im = page.images[0].as_pil()  # requires pillow
    display(im)

This error can occur when you trying to install pycurl.

In this case you should do

sudo apt-get install libcurl4-gnutls-dev librtmp-dev

(founded here: https://gist.github.com/lxneng/1031014 )

You should remove .Value from all option buttons because option buttons don't hold the resultant value, the option group control does. If you omit .Value then the default interface will report the option button status, as you are expecting. You should write all relevant code under commandbutton_click events because whenever the commandbutton is clicked the option button action will run.

If you want to run action code when the optionbutton is clicked then don't write an if loop for that.

EXAMPLE:

Sub CommandButton1_Click
    If OptionButton1 = true then
        (action code...)
    End if
End sub

Sub OptionButton1_Click   
    (action code...)
End sub

Take a look at PyCrypto. It supports Python 3.2 and does exactly what you want.

From their pip website:

>>> from Crypto.Cipher import AES
>>> obj = AES.new('This is a key123', AES.MODE_CFB, 'This is an IV456')
>>> message = "The answer is no"
>>> ciphertext = obj.encrypt(message)
>>> ciphertext
'\xd6\x83\x8dd!VT\x92\xaa`A\x05\xe0\x9b\x8b\xf1'
>>> obj2 = AES.new('This is a key123', AES.MODE_CFB, 'This is an IV456')
>>> obj2.decrypt(ciphertext)
'The answer is no'

If you want to encrypt a message of an arbitrary size use AES.MODE_CFB instead of AES.MODE_CBC.

Short arrow functions

For those who value short arrow function.

Hex2rgb

A arrow function version of David's Answer

const hex2rgb = h => [(x=parseInt(h,16)) >> 16 & 255,x >> 8 & 255, x & 255];

A more flexible solution that supports shortand hex or the hash #

const hex2rgb = h => {
    if(h[0] == '#') {h = h.slice(1)};
    if(h.length <= 3) {h = h[0]+h[0]+h[1]+h[1]+h[2]+h[2]};
    h = parseInt(h,16);
    return [h >> 16 & 255,h >> 8 & 255, h & 255];
};

Rgb2hex

const rgb2hex = (r,g,b) => ((1<<24)+(r<<16)+(g<<8)+b).toString(16).slice(1);

DISCLAIMER: this solution is not using Header.

If someone is looking for a lazy-lazy manner (also in WebApi), I'd suggest:

public YourResult Authorize([FromBody]BasicAuthCredentials credentials)

You are not getting from header, but at least you have an easy alternative. You can always check the object for null and fallback to header mechanism.

I believe that we are overthinking this,

function mouse_position(e)_x000D_
{_x000D_
//do stuff_x000D_
}

<body onmousemove="mouse_position(event)"></body>

Try this

java -jar <jar-file-name>.jar

Setup a DocumentListener on nameField. When nameField is updated, update your label.

http://download.oracle.com/javase/1.5.0/docs/api/javax/swing/JTextField.html

I have updated the controller to:

.controller('BusinessCtrl',
    function ($scope, $http, $location, Business, BusinessService, UserService, Photo) {
        $scope.$watch('createBusinessForm.$valid', function(newVal) {
            //$scope.valid = newVal;
            $scope.informationStatus = true;
        });
        ...

Add the active: false option (documentation)..

$("#accordion").accordion({ header: "h3", collapsible: true, active: false });

C++11

Problem

While the rules in C++03 about when you need typename and template are largely reasonable, there is one annoying disadvantage of its formulation

template<typename T>
struct A {
  typedef int result_type;

  void f() {
    // error, "this" is dependent, "template" keyword needed
    this->g<float>();

    // OK
    g<float>();

    // error, "A<T>" is dependent, "typename" keyword needed
    A<T>::result_type n1;

    // OK
    result_type n2; 
  }

  template<typename U>
  void g();
};

As can be seen, we need the disambiguation keyword even if the compiler could perfectly figure out itself that A::result_type can only be int (and is hence a type), and this->g can only be the member template g declared later (even if A is explicitly specialized somewhere, that would not affect the code within that template, so its meaning cannot be affected by a later specialization of A!).

Current instantiation

To improve the situation, in C++11 the language tracks when a type refers to the enclosing template. To know that, the type must have been formed by using a certain form of name, which is its own name (in the above, A, A<T>, ::A<T>). A type referenced by such a name is known to be the current instantiation. There may be multiple types that are all the current instantiation if the type from which the name is formed is a member/nested class (then, A::NestedClass and A are both current instantiations).

Based on this notion, the language says that CurrentInstantiation::Foo, Foo and CurrentInstantiationTyped->Foo (such as A *a = this; a->Foo) are all member of the current instantiation if they are found to be members of a class that is the current instantiation or one of its non-dependent base classes (by just doing the name lookup immediately).

The keywords typename and template are now not required anymore if the qualifier is a member of the current instantiation. A keypoint here to remember is that A<T> is still a type-dependent name (after all T is also type dependent). But A<T>::result_type is known to be a type - the compiler will "magically" look into this kind of dependent types to figure this out.

struct B {
  typedef int result_type;
};

template<typename T>
struct C { }; // could be specialized!

template<typename T>
struct D : B, C<T> {
  void f() {
    // OK, member of current instantiation!
    // A::result_type is not dependent: int
    D::result_type r1;

    // error, not a member of the current instantiation
    D::questionable_type r2;

    // OK for now - relying on C<T> to provide it
    // But not a member of the current instantiation
    typename D::questionable_type r3;        
  }
};

That's impressive, but can we do better? The language even goes further and requires that an implementation again looks up D::result_type when instantiating D::f (even if it found its meaning already at definition time). When now the lookup result differs or results in ambiguity, the program is ill-formed and a diagnostic must be given. Imagine what happens if we defined C like this

template<>
struct C<int> {
  typedef bool result_type;
  typedef int questionable_type;
};

A compiler is required to catch the error when instantiating D<int>::f. So you get the best of the two worlds: "Delayed" lookup protecting you if you could get in trouble with dependent base classes, and also "Immediate" lookup that frees you from typename and template.

Unknown specializations

In the code of D, the name typename D::questionable_type is not a member of the current instantiation. Instead the language marks it as a member of an unknown specialization. In particular, this is always the case when you are doing DependentTypeName::Foo or DependentTypedName->Foo and either the dependent type is not the current instantiation (in which case the compiler can give up and say "we will look later what Foo is) or it is the current instantiation and the name was not found in it or its non-dependent base classes and there are also dependent base classes.

Imagine what happens if we had a member function h within the above defined A class template

void h() {
  typename A<T>::questionable_type x;
}

In C++03, the language allowed to catch this error because there could never be a valid way to instantiate A<T>::h (whatever argument you give to T). In C++11, the language now has a further check to give more reason for compilers to implement this rule. Since A has no dependent base classes, and A declares no member questionable_type, the name A<T>::questionable_type is neither a member of the current instantiation nor a member of an unknown specialization. In that case, there should be no way that that code could validly compile at instantiation time, so the language forbids a name where the qualifier is the current instantiation to be neither a member of an unknown specialization nor a member of the current instantiation (however, this violation is still not required to be diagnosed).

Examples and trivia

You can try this knowledge on this answer and see whether the above definitions make sense for you on a real-world example (they are repeated slightly less detailed in that answer).

The C++11 rules make the following valid C++03 code ill-formed (which was not intended by the C++ committee, but will probably not be fixed)

struct B { void f(); };
struct A : virtual B { void f(); };

template<typename T>
struct C : virtual B, T {
  void g() { this->f(); }
};

int main() { 
  C<A> c; c.g(); 
}

This valid C++03 code would bind this->f to A::f at instantiation time and everything is fine. C++11 however immediately binds it to B::f and requires a double-check when instantiating, checking whether the lookup still matches. However when instantiating C<A>::g, the Dominance Rule applies and lookup will find A::f instead.

You need to alias the aggregate using the as keyword in order to call it from mysqli_fetch_assoc

$result=mysqli_query($conn,"SELECT count(*) as total from Students");
$data=mysqli_fetch_assoc($result);
echo $data['total'];

Because we can not use Where clause with aggregate functions like count(),min(), sum() etc. so having clause came into existence to overcome this problem in sql. see example for having clause go through this link

http://www.sqlfundamental.com/having-clause.php

The following query works. It uses each group to do the select instead of SelectMany. SelectMany works on each element from each collection. For example, in your query you have a result of 2 collections. SelectMany gets all the results, a total of 3, instead of each collection. The following code works on each IGrouping in the select portion to get your aggregate operations working correctly.

var results = from line in Lines
              group line by line.ProductCode into g
              select new ResultLine {
                ProductName = g.First().Name,
                Price = g.Sum(pc => pc.Price).ToString(),
                Quantity = g.Count().ToString(),
              };

Database class that checks if there is any existing database instance it will return previous instance.

   class Database {  
        public static $instance;  
         public static function getInstance(){  
            if(!isset(Database::$instance) ) {  
                Database::$instance = new Database();  
            }  
           return Database::$instance;  
         }  
         private function __cunstruct() {  
           /* private and cant create multiple objects */  
         }  
         public function getQuery(){  
            return "Test Query Data";  
         }  
    }  
    $dbObj = Database::getInstance();  
    $dbObj2 = Database::getInstance();  
    var_dump($dbObj);  
    var_dump($dbObj2);

you should use fmod(a,b)

While abs(x%y) < abs(y) is true mathematically, for floats it may not be true numerically due to roundoff.

For example, and assuming a platform on which a Python float is an IEEE 754 double-precision number, in order that -1e-100 % 1e100 have the same sign as 1e100, the computed result is -1e-100 + 1e100, which is numerically exactly equal to 1e100.

Function fmod() in the math module returns a result whose sign matches the sign of the first argument instead, and so returns -1e-100 in this case. Which approach is more appropriate depends on the application.

where x = a%b is used for integer modulo

do this in global.asax.cs:

protected void Application_Start()
{
  //string ServerSoftware = Context.Request.ServerVariables["SERVER_SOFTWARE"];
  string server = Context.Request.ServerVariables["SERVER_NAME"];
  string port = Context.Request.ServerVariables["SERVER_PORT"];
  HttpRuntime.Cache.Insert("basePath", "http://" + server + ":" + port + "/");
  // ...
}

works like a charm. this.Context.Request is there...

this.Request throws exception intentionally based on a flag

The body-parser module only handles JSON and urlencoded form submissions, not multipart (which would be the case if you're uploading files).

For multipart, you'd need to use something like connect-busboy or multer or connect-multiparty (multiparty/formidable is what was originally used in the express bodyParser middleware). Also FWIW, I'm working on an even higher level layer on top of busboy called reformed. It comes with an Express middleware and can also be used separately.

A slightly less ugly version of the same thing mentioned in pretty much all these answers:

UIViewController *rootViewController = [[self.navigationController viewControllers] firstObject];

in your case, I'd probably do something like:

inside your UINavigationController subclass:

- (UIViewController *)rootViewController
{
    return [[self viewControllers] firstObject];
}

then you can use:

UIViewController *rootViewController = [self.navigationController rootViewController];

edit

OP asked for a property in the comments.

if you like, you can access this via something like self.navigationController.rootViewController by just adding a readonly property to your header:

@property (nonatomic, readonly, weak) UIViewController *rootViewController;

Use re.escape

>>> import re
>>> re.escape(r'\ a.*$')
'\\\\\\ a\\.\\*\\$'
>>> print(re.escape(r'\ a.*$'))
\\\ a\.\*\$
>>> re.escape('www.stackoverflow.com')
'www\\.stackoverflow\\.com'
>>> print(re.escape('www.stackoverflow.com'))
www\.stackoverflow\.com

Repeating it here:

re.escape(string)

Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it.

As of Python 3.7 re.escape() was changed to escape only characters which are meaningful to regex operations.

Using Javascript:

 function getCookie(name) {
      let matches = document.cookie.match(new RegExp(
        "(?:^|; )" + name.replace(/([\.$?*|{}\(\)\[\]\\\/\+^])/g, '\\$1') + "=([^;]*)"
      ));
      return matches ? decodeURIComponent(matches[1]) : undefined;
    }

Just for documentation, sometimes you need to run the script as sudo:

sudo Rscript path/to/your/file.R

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
  FROM invoices
;

For more information on the format models you can use with TO_CHAR on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.

If you need just logical value (as it almost always is), the following one-liner will help you:

boolean ifIntsEqual = !((Math.max(a,b) - Math.min(a, b)) > 0);

And it works even in Java 1.5+, maybe even in 1.1 (i don't have one). Please tell us, if you can test it in 1.5-.

This one will do too:

boolean ifIntsEqual = !((Math.abs(a-b)) > 0);

Use CDATA tags:

 <![CDATA[
   This is some text with ampersands & other funny characters. >>
 ]]>

In my case, I hava writen the code in the file named "dns.py", it's conflict for the package, I have to rename the script filename.

You could do either:

dirname(__DIR__);

Or:

__DIR__ . '/..';

...but in a web server environment you will probably find that you are already working from current file's working directory, so you can probably just use:

'../'

...to reference the directory above. You can replace __DIR__ with dirname(__FILE__) before PHP 5.3.0.

You should also be aware what __DIR__ and __FILE__ refers to:

The full path and filename of the file. If used inside an include, the name of the included file is returned.

So it may not always point to where you want it to.

Easiest way is to open CMD or powershell as administrator and type

set PATH=%PATH%;C:\Python27

For Eclipse PDT in Mac OS, once you have deleted the actual workspace directory the option to select and switch to that workspace will still be available unless you delete the entry from Preferences >> General >> Startup and Shutdown >> Workspaces.

Parameters in the URL are GET parameters, a request body, if present, is POST data. So your basic premise is by definition not achievable.

You should choose whether to use POST or GET based on the action. Any destructive action, i.e. something that permanently changes the state of the server (deleting, adding, editing) should always be invoked by POST requests. Any pure "information retrieval" should be accessible via an unchanging URL (i.e. GET requests).

To make a POST request, you need to create a <form>. You could use Javascript to create a POST request instead, but I wouldn't recommend using Javascript for something so basic. If you want your submit button to look like a link, I'd suggest you create a normal form with a normal submit button, then use CSS to restyle the button and/or use Javascript to replace the button with a link that submits the form using Javascript (depending on what reproduces the desired behavior better). That'd be a good example of progressive enhancement.

There is a package called timeout-decorator that you can use to time out any python function.

@timeout_decorator.timeout(5)
def mytest():
    print("Start")
    for i in range(1,10):
        time.sleep(1)
        print("{} seconds have passed".format(i))

It uses the signals approach that some answers here suggest. Alternatively, you can tell it to use multiprocessing instead of signals (e.g. if you are in a multi-thread environment).

Rather than relying on errors, you can query INFORMATION_SCHEMA.TABLES to see if the table exists. If there's a record, it exists. If there's no record, it doesn't exist.

If you have worked with time/date formatting/parsing in other languages you might have noticed that the other languages use special placeholders for time/date formatting. For eg ruby language uses

%d for day
%Y for year

etc. Golang, instead of using codes such as above, uses date and time format placeholders that look like date and time only. Go uses standard time, which is:

Mon Jan 2 15:04:05 MST 2006  (MST is GMT-0700)
or 
01/02 03:04:05PM '06 -0700

So if you notice Go uses

01 for the day of the month,
02 for the month
03 for hours,
04 for minutes
05 for second
and so on

Therefore for example for parsing 2020-01-29, layout string should be 06-01-02 or 2006-01-02.

You can refer to the full placeholder layout table at this link - https://golangbyexample.com/parse-time-in-golang/

If you set the server output in ON mode before the entire code, it works, otherwise put_line() will not work. Try it!

The code is,

set serveroutput on;
CREATE OR REPLACE PROCEDURE PROC1(invoicenr IN NUMBER, amnt OUT NUMBER)
AS BEGIN
SELECT AMOUNT INTO amnt FROM INVOICE WHERE INVOICE_NR = invoicenr;
END;

And then call the function as it is:

DECLARE
amount NUMBER;
BEGIN
PROC1(1000001, amount);
dbms_output.put_line(amount);
END;

In Solution Explorer, please select files you want to copied to output directory and assign two properties: - Build action = Content - Copy to Output Directory = Copy Always

This will do the trick.

I tried one of the previous answers in a web app (actually an Azure web role running locally) and it didn't quite work. However, this similar approach did work:

var map = new ExeConfigurationFileMap { ExeConfigFilename = "MyComponent.dll.config" };
var path = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None).FilePath;

The config file turned out to be in C:\Program Files\IIS Express\MyComponent.dll.config. Interesting place for it.

$result = mysqli_query($con,"SELECT `note` FROM `glogin_users` WHERE email = '".$email."'");
while($row = mysqli_fetch_array($result))
echo $row['note'];

If you want to change all columns names, try df.toDF(*cols)

It only appeared in my Chrome browser a few days ago too. I checked a few websites I developed in the past that haven't been changed and they also show the same error. So I'd suggest it's not down to your coding, rather a bug in the latest Chrome release.

You have 3 options: Chrome (via Developer Tools -> Network tab), Wireshark, and Fiddler (via Log tab), however they all very basic. If you have very high volume of traffic or each frame is very large, it becomes very difficult to use them for debugging.

You can however use Fiddler with FiddlerScript to inspect WebSocket traffic in the same way you inpect HTTP traffic. Few advantages of this solution are that you can leverage many other functionalities in Fiddler, such as multiple inspectors (HexView, JSON, SyntaxView), compare packets, and find packets, etc.

Please refer to my recently written article on CodeProject, which show you how to Debug/Inspect WebSocket traffic with Fiddler (with FiddlerScript). http://www.codeproject.com/Articles/718660/Debug-Inspect-WebSocket-traffic-with-Fiddler

Today, I've got a similar error:

Servlet.service() for servlet [remoting] in context with path [/***] threw exception [Request processing failed; nested exception is java.lang.RuntimeException: buildDocument failed.] with root cause org.xml.sax.SAXParseException; lineNumber: 19; columnNumber: 91; An invalid XML character (Unicode: 0xc) was found in the value of attribute "text" and element is "label".

After my first encouter with the error, I had re-typed the entire line by hand, so that there was no way for a special character to creep in, and Notepad++ didn't show any non-printable characters (black on white), nevertheless I got the same error over and over.

When I looked up what I've done different than my predecessors, it turned out it was one additional space just before the closing /> (as I've heard was recommended for older parsers, but it shouldn't make any difference anyway, by the XML standards):

<label text="this label's text" layout="cell 0 0, align left" />

When I removed the space:

<label text="this label's text" layout="cell 0 0, align left"/>

everything worked just fine.

So it's definitely a misleading error message.

What about this?

function replaceLast(x, y, z){
  var a = x.split("");
  a[x.lastIndexOf(y)] = z;
  return a.join("");
}

replaceLast("Hello world!", "l", "x"); // Hello worxd!

You can use ImageMagick without separating the first page of the PDF with other tools. Just do

convert -density 288 cover.pdf[0] -resize 25% cover.png

Here I increase the nominal density by 400% (72*4=288) and then resize by 1/4 (25%). This gives a much better quality for the resulting png.

However, if the PDF is CMYK, PNG does not support that. It would need to be converted to sRGB, especially if it has transparency, since Ghostscript cannot handle CMYK with alpha.

convert -density 288 -colorspace sRGB -resize 25% cover.pdf[0] cover.png

Well, you're going to have to check for null somewhere. You could do something like this:

from item in db.vw_Dropship_OrderItems
         where (listStatus == null || listStatus.Contains(item.StatusCode)) 
            && (listMerchants == null || listMerchants.Contains(item.MerchantId))
         select item;

Here is a simple example of group by in .net core 2.1

var query = this.DbContext.Notifications.
            Where(n=> n.Sent == false).
            GroupBy(n => new { n.AppUserId })
            .Select(g => new { AppUserId = g.Key, Count =  g.Count() });

var query2 = from n in this.DbContext.Notifications
            where n.Sent == false
            group n by n.AppUserId into g
            select new { id = g.Key,  Count = g.Count()};

Which translates to:

SELECT [n].[AppUserId], COUNT(*) AS [Count]
FROM [Notifications] AS [n]
WHERE [n].[Sent] = 0
GROUP BY [n].[AppUserId]

Echoing f.in and f.out will seperate the concept of what to loop and what not to loop when used in a for /f loop.

::Get the files seperated
echo f.in>files_to_pass_through.txt
echo f.out>>files_to_pass_through.txt

for /F %%a in (files_to_pass_through.txt) do (
for /R %%b in (*.*) do (
if "%%a" NEQ "%%b" (
echo %%b>>dont_pass_through_these.txt
)
)
)
::I'm assuming the base name is the whole string "f".
::If I'm right then all the files begin with "f".
::So all you have to do is display "f". right?
::But that would be too easy.
::Let's do this the right way.
for /f %%C in (dont_pass_through_these.txt)
::displays the filename and not the extention
echo %~nC
)

Although you didn't ask, a good way to pass commands into f.in and f.out would be to...

for /F %%D "tokens=*" in (dont_pass_through_these.txt) do (
for /F %%E in (%%D) do (
start /wait %%E
)
)

I apologize if I did not answer this correctly. The question was very hard for me to read.

If that question is connected to your other Hudson questions use the command they provide. This way with XML from the command line:

$ curl -X POST -d '<run>...</run>' \
http://user:pass@myhost:myport/path/of/url

You need to change it a little bit to read from a file:

 $ curl -X POST -d @myfilename http://user:pass@myhost:myport/path/of/url

Read the manpage. following an abstract for -d Parameter.

-d/--data

(HTTP) Sends the specified data in a POST request to the HTTP server, in the same way that a browser does when a user has filled in an HTML form and presses the submit button. This will cause curl to pass the data to the server using the content-type application/x-www-form-urlencoded. Compare to -F/--form.

-d/--data is the same as --data-ascii. To post data purely binary, you should instead use the --data-binary option. To URL-encode the value of a form field you may use --data-urlencode.

If any of these options is used more than once on the same command line, the data pieces specified will be merged together with a separating &-symbol. Thus, using '-d name=daniel -d skill=lousy' would generate a post chunk that looks like 'name=daniel&skill=lousy'.

If you start the data with the letter @, the rest should be a file name to read the data from, or - if you want curl to read the data from stdin. The contents of the file must already be URL-encoded. Multiple files can also be specified. Posting data from a file named 'foobar' would thus be done with --data @foobar.

Please see this sample implementation of filter to understand how it works in Python 3:

def my_filter(function, iterable):
    """my_filter(function or None, iterable) --> filter object

    Return an iterator yielding those items of iterable for which function(item)
    is true. If function is None, return the items that are true."""
    if function is None:
        return (item for item in iterable if item)
    return (item for item in iterable if function(item))

The following is an example of how you might use filter or my_filter generators:

>>> greetings = {'hello'}
>>> spoken = my_filter(greetings.__contains__, ('hello', 'goodbye'))
>>> print('\n'.join(spoken))
hello

For what it's worth, checking which curl is being run is significant too.

A user on a shared machine I maintain had been getting this error. But the cause turned out to be because they'd installed Anaconda (http://continuum.io). Doing so put Anaconda's binary path before the standard $PATH, and it comes with its own curl binary, which had trouble finding the default certs that were installed on this Ubuntu machine.

As I have found and wrote in another topic - this applies to angular < 7 (not sure how it is in 7+)

Just for the future

we need to observe that [(ngModel)]="hero.name" is just a short-cut that can be de-sugared to: [ngModel]="hero.name" (ngModelChange)="hero.name = $event".

So if we de-sugar code we would end up with:

<select (ngModelChange)="onModelChange()" [ngModel]="hero.name" (ngModelChange)="hero.name = $event">

or

<[ngModel]="hero.name" (ngModelChange)="hero.name = $event" select (ngModelChange)="onModelChange()">

If you inspect the above code you will notice that we end up with 2 ngModelChange events and those need to be executed in some order.

Summing up: If you place ngModelChange before ngModel, you get the $event as the new value, but your model object still holds previous value. If you place it after ngModel, the model will already have the new value.

I think the easiest way to do that is by using apache collections api - CollectionUtils.subtract(list1,list2) as long the lists are of the same type.

One solution where we need not know the width/height of the dialog and then assume the margins.

Html:

<div id="dialog-contain">  <-- This div because I assume you might have a display that is not a flex. '
    <div id="block">
        <div id="centered">
            stuffs
        </div>
    </div>
</div>

Css:

#dialog-contain { // full page container.
    position: absolute;
    height: 100%;
    width: 100%;
    top: 0;
    left: 0;
    ...
}

#block {  // another container simply with display:flex.
    display: flex;
    height: 100%;
    width: 100%;
    justify-content: center;
}

#centered {   // another container that is always centered.
    align-self: center;
}

Java 7 introduced Files.readAllBytes(), which can read a PDF into a byte[] like so:

import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.Files;

Path pdfPath = Paths.get("/path/to/file.pdf");
byte[] pdf = Files.readAllBytes(pdfPath);

EDIT:

Thanks Farooque for pointing out: this will work for reading any kind of file, not just PDFs. All files are ultimately just a bunch of bytes, and as such can be read into a byte[].

This reply may be late but it may help users having similar problem. The opencv-contrib (available at https://github.com/opencv/opencv_contrib/releases) contains extra modules but the build procedure has to be done from core opencv (available at from https://github.com/opencv/opencv/releases) modules.

Follow below steps (assuming you are building it using CMake GUI)

1. Download openCV (from https://github.com/opencv/opencv/releases) and unzip it somewhere on your computer. Create build folder inside it

2. Download exra modules from OpenCV. (from https://github.com/opencv/opencv_contrib/releases). Ensure you download the same version.

3. Unzip the folder.

4. Open CMake

5. Click Browse Source and navigate to your openCV folder.

6. Click Browse Build and navigate to your build Folder.

7. Click the configure button. You will be asked how you would like to generate the files. Choose Unix-Makefile from the drop down menu and Click OK. CMake will perform some tests and return a set of red boxes appear in the CMake Window.

8. Search for "OPENCV_EXTRA_MODULES_PATH" and provide the path to modules folder (e.g. /Users/purushottam_d/Programs/OpenCV3_4_5_contrib/modules)

9. Click Configure again, then Click Generate.

10. Go to build folder

# cd build
# make
# sudo make install

11. This will install the opencv libraries on your computer.

I ran into the same issue. Whenever I ran my test, it kept saying classes not found in the classpath. I tried to fix the testng.xml file, clean up the project and pretty much everything the answers say here, but none worked. Finally I checked my referenced libraries in build path and there were 34 invalid libraries, turns out I had renamed one of the folders from the path that I had taken the jar files from. I fixed the path and the test ran successfully.

So it might be fruitful to check if there are any errors in the referenced jar files before trying the other methods to fix this issue.

double  i = 2+Math.random()*100;

Webkit is the html/css rendering engine used in Apple's Safari browser, and in Google's Chrome. css values prefixes with -webkit- are webkit-specific, they're usually CSS3 or other non-standardised features.

to answer update 2 w3c is the body that tries to standardize these things, they write the rules, then programmers write their rendering engine to interpret those rules. So basically w3c says DIVs should work "This way" the engine-writer then uses that rule to write their code, any bugs or mis-interpretations of the rules cause the compatibility issues.

Try putting the height into one of the cells, like this:

<table class="tableContainer" cellspacing="10px">
 <tr>
  <td style="height:15px;">NHS Number</td>
  <td>&#160;</td>

Note however, that you won't be able to make the cell smaller than the content requires it to be. In that case you would have to make the text smaller first.

I've just been struggling with MSVC2005 to use the std::string(char*) constructor just like the top-rated answer. As I see this variant listed as #4 on always-trusted http://en.cppreference.com/w/cpp/string/basic_string/basic_string , I figure even an old compiler offers this.

It has taken me so long to realize that this constructor absolute refuses to match with (unsigned char*) as an argument ! I got these incomprehensible error messages about failure to match with std::string argument type, which was definitely not what I was aiming for. Just casting the argument with std::string((char*)ucharPtr) solved my problem... duh !

Please put this code in head section

<link href='http://fonts.googleapis.com/css?family=Lato:400,700' rel='stylesheet' type='text/css'>

and use font-family: 'Lato', sans-serif; in your css. For example:

h1 {
    font-family: 'Lato', sans-serif;
    font-weight: 400;
}

Or you can use manually also

Generate .ttf font from fontSquiral

and can try this option

    @font-face {
        font-family: "Lato";
        src: url('698242188-Lato-Bla.eot');
        src: url('698242188-Lato-Bla.eot?#iefix') format('embedded-opentype'),
        url('698242188-Lato-Bla.svg#Lato Black') format('svg'),
        url('698242188-Lato-Bla.woff') format('woff'),
        url('698242188-Lato-Bla.ttf') format('truetype');
        font-weight: normal;
        font-style: normal;
}

Called like this

body {
  font-family: 'Lato', sans-serif;
}

First of all don't make the mock static. Make it a private field. Just put your setUp class in the @Before not @BeforeClass. It might be run a bunch, but it's cheap.

Secondly, the way you have it right now is the correct way to get a mock to return something different depending on the test.

First, select all code using command+a

Second, hold key ctr and then press i

the whole selected code will nicely indent.

why not printf '%02d' $num? See help printf for this internal bash command.

Here is some code that will give you the general idea.

You need to create a custom ClientHttpRequestFactory in order to trust the certificate. It looks like this:

final ClientHttpRequestFactory clientHttpRequestFactory =
        new MyCustomClientHttpRequestFactory(org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER, serverInfo);
    restTemplate.setRequestFactory(clientHttpRequestFactory);

This is the implementation for MyCustomClientHttpRequestFactory:

public class MyCustomClientHttpRequestFactory  extends SimpleClientHttpRequestFactory {

private final HostnameVerifier hostNameVerifier;
private final ServerInfo serverInfo;

public MyCustomClientHttpRequestFactory (final HostnameVerifier hostNameVerifier,
    final ServerInfo serverInfo) {
    this.hostNameVerifier = hostNameVerifier;
    this.serverInfo = serverInfo;
}

@Override
protected void prepareConnection(final HttpURLConnection connection, final String httpMethod)
    throws IOException {
    if (connection instanceof HttpsURLConnection) {
        ((HttpsURLConnection) connection).setHostnameVerifier(hostNameVerifier);
        ((HttpsURLConnection) connection).setSSLSocketFactory(initSSLContext()
            .getSocketFactory());
    }
    super.prepareConnection(connection, httpMethod);
}

private SSLContext initSSLContext() {
    try {
        System.setProperty("https.protocols", "TLSv1");

        // Set ssl trust manager. Verify against our server thumbprint
        final SSLContext ctx = SSLContext.getInstance("TLSv1");
        final SslThumbprintVerifier verifier = new SslThumbprintVerifier(serverInfo);
        final ThumbprintTrustManager thumbPrintTrustManager =
            new ThumbprintTrustManager(null, verifier);
        ctx.init(null, new TrustManager[] { thumbPrintTrustManager }, null);
        return ctx;
    } catch (final Exception ex) {
        LOGGER.error(
            "An exception was thrown while trying to initialize HTTP security manager.", ex);
        return null;
    }
}

In this case my serverInfo object contains the thumbprint of the server. You need to implement the TrustManager interface to get the SslThumbprintVerifier or any other method you want to verify your certificate (you can also decide to also always return true).

The value org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER allows all host names. If you need to verify the host name, you will need to implement it differently.

I'm not sure about the user and password and how you implemented it. Often, you need to add a header to the restTemplate named Authorization with a value that looks like this: Base: <encoded user+password>. The user+password must be Base64 encoded.

It is possible that you compiled your binary with incompatible architecture settings on your build host vs. your execution host. Can you please have a look at the enabled target settings via

g++ {all-your-build-flags-here} -Q -v --help=target

on your build host? In particular, the COLLECT_GCC_OPTIONS variable may give you valuable debug info. Then have a look at the CPU capabilities on your execution host via

cat /proc/cpuinfo | grep -m1 flags

Look out for mismatches such as -msse4.2 [enabled] on your build host but a missing sse4_2 flag in the CPU capabilities.

If that doesn't help, please provide the output of ldd commonKT on both build and execution host.

Sat Jun 25 09:38:51 [initandlisten] listen(): bind() failed errno:98 Address already in use for socket: 0.0.0.0:27017

is self-speaking.

Another instance of mongod is already running and allocating the MongoDB default port which is 27017.

Either kill the other process or use a different port.

Added: I found something that should do the trick right away, but the rest of the code below also offers an alternative.

Use the subplots_adjust() function to move the bottom of the subplot up:

fig.subplots_adjust(bottom=0.2) # <-- Change the 0.02 to work for your plot.

Then play with the offset in the legend bbox_to_anchor part of the legend command, to get the legend box where you want it. Some combination of setting the figsize and using the subplots_adjust(bottom=...) should produce a quality plot for you.

Alternative: I simply changed the line:

fig = plt.figure(1)

to:

fig = plt.figure(num=1, figsize=(13, 13), dpi=80, facecolor='w', edgecolor='k')

and changed

lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,0))

to

lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,-0.02))

and it shows up fine on my screen (a 24-inch CRT monitor).

Here figsize=(M,N) sets the figure window to be M inches by N inches. Just play with this until it looks right for you. Convert it to a more scalable image format and use GIMP to edit if necessary, or just crop with the LaTeX viewport option when including graphics.

It depends on the implementation of your JSON writer/parser. Microsoft's DataContractJsonSerializer seems to have a hard limit around 8kb (8192 I think), and it will error out for larger strings.

Edit: We were able to resolve the 8K limit for JSON strings by setting the MaxJsonLength property in the web config as described in this answer: https://stackoverflow.com/a/1151993/61569

I was having same issue, way i have resolved is:

opened the MySQL installer. i was having a Reconfigure link on MYSQL Server row.

Clicked on it, it does reinstalled MySQL Server. after that opened MySQL Workbench, and it was working fine.

There are several ways to do this:

$collection = Mage::getModel('...')
            ->getCollection()
            ->setPageSize(20)
            ->setCurPage(1);

Will get first 20 records.

Here is the alternative and maybe more readable way:

$collection = Mage::getModel('...')->getCollection();
$collection->getSelect()->limit(20);

This will call Zend Db limit. You can set offset as second parameter.

I have made a little example using css

.hover {_x000D_
  position: relative;_x000D_
  top: 50px;_x000D_
  left: 50px;_x000D_

_x000D_
.tooltip {_x000D_
  /* hide and position tooltip */_x000D_
  top: -10px;_x000D_
  background-color: black;_x000D_
  color: white;_x000D_
  border-radius: 5px;_x000D_
  opacity: 0;_x000D_
  position: absolute;_x000D_

You need to put the .jar file into your classpath when compiling/running your code. Then you just use standard imports of the classes in the .jar.

import csv
cols = [' V1', ' I1'] # define your columns here, check the spaces!
data = [[] for col in cols] # this creates a list of **different** lists, not a list of pointers to the same list like you did in [[]]*len(positions) 
with open('data.csv', 'r') as f:
    for rec in csv.DictReader(f):
        for l, col in zip(data, cols):
            l.append(float(rec[col]))
print data

# [[3.0, 3.0], [0.01, 0.01]]

Also note, if you just want to see the changed files between the last commit and the one before it. This works fine: git show --name-only

Or try an alternate method using Time datatype:

DECLARE @MyTime TIME = '03:30:00', @MyDay DATETIME = CAST(GETDATE() AS DATE)

SELECT @MyDay+@MyTime

First page (scroll down to see the second page)_x000D_
<div style="break-after:page"></div>_x000D_
Second page_x000D_
<br>_x000D_
<br>_x000D_
<button onclick="window.print();return false;" />Print (to see the result) </button>

Just add this where you need the page to go to the next one (the text "page 1" will be on page 1 and the text "page 2" will be on the second page).

Page 1
<div style='page-break-after:always'></div>
Page 2

This works too:

First page (there is a break after this)
<div style="break-after:page"></div>
Second page (This will be printed in the second page)

Use chars:

Dim firstChar As char;
firstChar = s.Chars(0);

The accepted answer by @Meherzad only works if the data is in a particular order. It happens to work with the data from the OP question. In my case, I had to modify it to work with my data.

Note This only works when every record's "id" (col1 in the question) has a value GREATER THAN that record's "parent id" (col3 in the question). This is often the case, because normally the parent will need to be created first. However if your application allows changes to the hierarchy, where an item may be re-parented somewhere else, then you cannot rely on this.

This is my query in case it helps someone; note it does not work with the given question because the data does not follow the required structure described above.

select t.col1, t.col2, @pv := t.col3 col3
from (select * from table1 order by col1 desc) t
join (select @pv := 1) tmp
where t.col1 = @pv

The difference is that table1 is being ordered by col1 so that the parent will be after it (since the parent's col1 value is lower than the child's).

You can define your Enum as following code :

public enum Verbosity 
{
   BRIEF, NORMAL, FULL, ACTION_NOT_VALID;
   private int value;

   public int getValue()
   {
     return this.value;
   } 

   public static final Verbosity getVerbosityByValue(int value)
   {
     for(Verbosity verbosity : Verbosity.values())
     {
        if(verbosity.getValue() == value)
            return verbosity ;
     }

     return ACTION_NOT_VALID;
   }

   @Override
   public String toString()
   {
      return ((Integer)this.getValue()).toString();
   }
};

See following link for more clarification

Hi we can use ToLower Method sometimes it is not filter.

EmployeeId = Session["EmployeeID"].ToString();
var rows = dtCrewList.AsEnumerable().Where
   (row => row.Field<string>("EmployeeId").ToLower()== EmployeeId.ToLower());

   if (rows.Any())
   {
        tblFiltered = rows.CopyToDataTable<DataRow>();
   }

if you generate new angular project using "ng new", you may skip a generating of spec.ts files. For this you should apply --skip-tests option.

Few hints to handle such error/exception for Android Apps:

1. Activities & Application have methods like:

   • onLowMemory
   • onTrimMemory Handle these methods to watch on memory usage.

2. tag in Manifest can have attribute 'largeHeap' set to TRUE, which requests more heap for App sandbox.

3. Managing in-memory caching & disk caching:

   • Images and other data could have been cached in-memory while app running, (locally in activities/fragment and globally); should be managed or removed.

4. Use of WeakReference, SoftReference of Java instance creation , specifically to files.

5. If so many images, use proper library/data structure which can manage memory, use samling of images loaded, handle disk-caching.

6. Handle OutOfMemory exception

7. Follow best practices for coding

   • Leaking of memory (Don't hold everything with strong reference)

8. Minimize activity stack e.g. number of activities in stack (Don't hold everything on context/activty)

   • Context makes sense, those data/instances not required out of scope (activity and fragments), hold them into appropriate context instead global reference-holding.

9. Minimize the use of statics, many more singletons.

10. Take care of OS basic memory fundametals

    • Memory fragmentation issues

11. Involk GC.Collect() manually sometimes when you are sure that in-memory caching no more needed.

I was also using the official image (FROM postgres) and I was able to change the config by executing the following commands.

The first thing is to locate the PostgreSQL config file. This can be done by executing this command in your running database.

SHOW config_file;

I my case it returns /data/postgres/postgresql.conf.

The next step is to find out what is the hash of your running PostgreSQL docker container.

docker ps -a

This should return a list of all the running containers. In my case it looks like this.

...
0ba35e5427d9    postgres    "docker-entrypoint.s…" ....
...

Now you have to switch to the bash inside your container by executing:

docker exec -it 0ba35e5427d9 /bin/bash

Inside the container check if the config is at the correct path and display it.

cat /data/postgres/postgresql.conf

I wanted to change the max connections from 100 to 1000 and the shared buffer from 128MB to 3GB. With the sed command I can do a search and replace with the corresponding variables ins the config.

sed -i -e"s/^max_connections = 100.*$/max_connections = 1000/" /data/postgres/postgresql.conf
sed -i -e"s/^shared_buffers = 128MB.*$/shared_buffers = 3GB/" /data/postgres/postgresql.conf

The last thing we have to do is to restart the database within the container. Find out which version you of PostGres you are using.

cd /usr/lib/postgresql/
ls 

In my case its 12 So you can now restart the database by executing the following command with the correct version in place.

su - postgres -c "PGDATA=$PGDATA /usr/lib/postgresql/12/bin/pg_ctl -w restart"

This worked for me.

 1. git fetch --all
 2. git reset --hard origin/{branch_name}

If you are setting up the ANDROID_HOME environment on MacOS Catalina , .bash_profile is no longer apple's default shell and it won't persist your path variables. Use .zprofile instead and follow the environment setup instructions in react-native documentation or others. .bash_profile will keep creating new file which won't make the path permanent or persist on closing the terminal on your system path.

Modified as it's providing answer to the frustration of setting up android_home environment on MacOS.

import random
rgb_full="(" + str(random.randint(1,256))  + "," + str(random.randint(1,256))  + "," + str(random.randint(1,256))  + ")"

You can use array slicing:

Entry.objects.all()[:1].get()

Which can be used with .filter():

Entry.objects.filter()[:1].get()

You wouldn't want to first turn it into a list because that would force a full database call of all the records. Just do the above and it will only pull the first. You could even use .order_by() to ensure you get the first you want.

Be sure to add the .get() or else you will get a QuerySet back and not an object.

rolling back to node v10.17.0 fixed the problem to me.

You can use nvm to do so:

https://github.com/nvm-sh/nvm

> nvm install 10.17.0
> nvm use 10.17.0
> node -v
10.17.0

I found that just using the connectivity package was not enough to tell if the internet was available or not. In Android it only checks if there is WIFI or if mobile data is turned on, it does not check for an actual internet connection . During my testing, even with no mobile signal ConnectivityResult.mobile would return true.

With IOS my testing found that the connectivity plugin does correctly detect if there is an internet connection when the phone has no signal, the issue was only with Android.

The solution I found was to use the data_connection_checker package along with the connectivity package. This just makes sure there is an internet connection by making requests to a few reliable addresses, the default timeout for the check is around 10 seconds.

My finished isInternet function looked a bit like this:

  Future<bool> isInternet() async {
    var connectivityResult = await (Connectivity().checkConnectivity());
    if (connectivityResult == ConnectivityResult.mobile) {
      // I am connected to a mobile network, make sure there is actually a net connection.
      if (await DataConnectionChecker().hasConnection) {
        // Mobile data detected & internet connection confirmed.
        return true;
      } else {
        // Mobile data detected but no internet connection found.
        return false;
      }
    } else if (connectivityResult == ConnectivityResult.wifi) {
      // I am connected to a WIFI network, make sure there is actually a net connection.
      if (await DataConnectionChecker().hasConnection) {
        // Wifi detected & internet connection confirmed.
        return true;
      } else {
        // Wifi detected but no internet connection found.
        return false;
      }
    } else {
      // Neither mobile data or WIFI detected, not internet connection found.
      return false;
    }
  }

The if (await DataConnectionChecker().hasConnection) part is the same for both mobile and wifi connections and should probably be moved to a separate function. I've not done that here to leave it more readable.

This is my first Stack Overflow answer, hope it helps someone.

Try this out:-

http://jsfiddle.net/adiioo7/vmfbA/

Use

document.body.innerHTML += '<div style="position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;"></div>';

instead of

document.body.innerHTML = '<div style="position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000;"></div>';

Edit:- Ideally you should use body.appendChild method instead of changing the innerHTML

var elem = document.createElement('div');
elem.style.cssText = 'position:absolute;width:100%;height:100%;opacity:0.3;z-index:100;background:#000';
document.body.appendChild(elem);

If you're OK with not using <p>s (only <div>s and <span>s), this solution might even allow you to align your inline-blocks center or right, if you want to (or just keep them left, the way you originally asked for). While the solution might still work with <p>s, I don't think the resulting HTML code would be quite correct, but it's up to you anyways.

The trick is to wrap each one of your <span>s with a corresponding <div>. This way we're taking advantage of the line break caused by the <div>'s display: block (default), while still keeping the visual green box tight to the limits of the text (with your display: inline-block declaration).

.text span {_x000D_
   background:rgba(165, 220, 79, 0.8);_x000D_
   display:inline-block;_x000D_
   padding:7px 10px;_x000D_
   color:white;_x000D_
}_x000D_
.large {  font-size:80px }

<div class="text">_x000D_
  <div><span class="medium">We</span></div>_x000D_
  <div><span class="large">build</span></div>_x000D_
  <div><span class="medium">the</span></div>_x000D_

This creates another array without those columns:

"What is a “static” function in C?"

Let's start at the beginning.

It´s all based upon a thing called "linkage":

"An identifier declared in different scopes or in the same scope more than once can be made to refer to the same object or function by a process called linkage. 29)There are three kinds of linkage: external, internal, and none."

Source: C18, 6.2.2/1

"In the set of translation units and libraries that constitutes an entire program, each declaration of a particular identifier with external linkage denotes the same object or function. Within one translation unit, each declaration of an identifier with internal linkage denotes the same object or function. Each declaration of an identifier with no linkage denotes a unique entity."

Source: C18, 6.2.2/2

If a function is defined without a storage-class specifier, the function has external linkage by default:

"If the declaration of an identifier for a function has no storage-class specifier, its linkage is determined exactly as if it were declared with the storage-class specifier extern."

Source: C18, 6.2.2/5

That means that - if your program is contained of several translation units/source files (.c or .cpp) - the function is visible in all translation units/source files your program has.

This can be a problem in some cases. What if you want to use f.e. two different function (definitions), but with the same function name in two different contexts (actually the file-context).

In C and C++, the static storage-class qualifier applied to a function at file scope (not a static member function of a class in C++ or a function within another block) now comes to help and signifies that the respective function is only visible inside of the translation unit/source file it was defined in and not in the other TLUs/files.

"If the declaration of a file scope identifier for an object or a function contains the storage-class specifier static, the identifier has internal linkage. 30)"

30. A function declaration can contain the storage-class specifier static only if it is at file scope; see 6.7.1.

Source: C18, 6.2.2/3

Thus, A static function only makes sense, iff:

1. Your program is contained of several translation units/source files (.c or .cpp).

and

2. You want to limit the scope of a function to the file, in which the specific function is defined.

If not both of these requirements match, you don't need to wrap your head around about qualifying a function as static.

Side Notes:

• As already mentioned, A static function has absolutely no difference at all between C and C++, as this is a feature C++ inherited from C.

It does not matter that in the C++ community, there is a heartbreaking debate about the depreciation of qualifying functions as static in comparison to the use of unnamed namespaces instead, first initialized by a misplaced paragraph in the C++03 standard, declaring the use of static functions as deprecated which soon was revised by the committee itself and removed in C++11.

This was subject to various SO questions:

Unnamed/anonymous namespaces vs. static functions

Superiority of unnamed namespace over static?

Why an unnamed namespace is a "superior" alternative to static?

Deprecation of the static keyword... no more?

In fact, it is not deprecated per C++ standard yet. Thus, the use of static functions is still legit. Even if unnamed namespaces have advantages, the discussion about using or not using static functions in C++ is subject to one´s one mind (opinion-based) and with that not suitable for this website.

you can also use for loop to append or write data to a file. example:

for i in {1..10}; do echo "Hello Linux Terminal"; >> file.txt done

">>" is used to append.

">" is used to write.

You can do either…

$qb->where('e.fecha BETWEEN :monday AND :sunday')
   ->setParameter('monday', $monday->format('Y-m-d'))
   ->setParameter('sunday', $sunday->format('Y-m-d'));

or…

$qb->where('e.fecha > :monday')
   ->andWhere('e.fecha < :sunday')
   ->setParameter('monday', $monday->format('Y-m-d'))
   ->setParameter('sunday', $sunday->format('Y-m-d'));

cfsetispeed (&tty, (speed_t)B9600);

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

}

Write

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

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

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

At last, read:

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

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

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

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

This one worked for me. Thank you all!

Instant corresponds to time on the prime meridian (Greenwich).

Whereas LocalDateTime relative to OS time zone settings, and

cannot represent an instant without additional information such as an offset or time-zone.

Just trigger stuff, set some flag, return false. If flag is set - do nothing.

I used this code,

 <div style="visibility:hidden">
    <audio autoplay loop>
        <source src="Aakaasam-Yemaaya Chesave.mp3">
    </audio> 
</div>

It is working well but i want stop and pause button. So, we can stop if we don't want to listen.

2019 Answer Late, but hope it helps somebody

This will make sure you won't get null on an empty textfield

• Textfield value is always 0
• When backspacing, you will end with 0
• When value is 0 and you start typing, 0 will be replaced with the actual number

// This will make sure that value never is null when textfield is empty

const minimum = 0;   

export default (props) => {
    const [count, changeCount] = useState(minimum);

    function validate(count) {
        return parseInt(count) | minimum
    }

    function handleChangeCount(count) {
        changeCount(validate(count))
    }

    return (
        <Form>
            <FormGroup>
                <TextInput
                    type="text"
                    value={validate(count)}
                    onChange={handleChangeCount}
                />
            </FormGroup>

• @@IDENTITY returns the last identity value generated for any table in the current session, across all scopes. You need to be careful here, since it's across scopes. You could get a value from a trigger, instead of your current statement.

• SCOPE_IDENTITY() returns the last identity value generated for any table in the current session and the current scope. Generally what you want to use.

• IDENT_CURRENT('tableName') returns the last identity value generated for a specific table in any session and any scope. This lets you specify which table you want the value from, in case the two above aren't quite what you need (very rare). Also, as @Guy Starbuck mentioned, "You could use this if you want to get the current IDENTITY value for a table that you have not inserted a record into."

• The OUTPUT clause of the INSERT statement will let you access every row that was inserted via that statement. Since it's scoped to the specific statement, it's more straightforward than the other functions above. However, it's a little more verbose (you'll need to insert into a table variable/temp table and then query that) and it gives results even in an error scenario where the statement is rolled back. That said, if your query uses a parallel execution plan, this is the only guaranteed method for getting the identity (short of turning off parallelism). However, it is executed before triggers and cannot be used to return trigger-generated values.

Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.

Have in mind also that,

large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.

-- Announcement of YUI development being ceased

That said, below are a number of Ext JS alternatives currently available.

Leading client widget libraries

1. Blueprint is a React-based UI toolkit developed by big data analytics company Palantir in TypeScript, and "optimized for building complex data-dense interfaces for desktop applications". Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.

   Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

   Sandbox / demo • GitHub • Docs

2. Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.

   

   Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.

   Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.

   The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).

   The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.

   Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

3. react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.

4. kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).

   

   Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.

   A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

   [Wikipedia] • GitHub/Telerik • Demos • Playground • Tools

5. OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.

   

   The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.

   The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.

   Wikipedia • GitHub • Mobile-first controls demos • Desktop controls demos • SO

6. DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.

   

   Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.

7. Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.

   

8. Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).

   The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.

9. PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.

10. qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).

    Mobile themes look modern but desktop themes look old (gradients).

11. jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.

12. angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).

13. DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.

    

    Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.

    Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.

    With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.

14. Enyo - front-end library aimed at mobile and TV apps (e.g. large touch-friendly controls). Developed by LG Electronix and Apache-licensed on GitHub.

15. The radical Cappuccino - Objective-J (a superset of JavaScript) instead of HTML+CSS+DOM

16. Mochaui, MooTools UI Library User Interface Library. <300 GitHub stars.

17. CrossUI - cross-browser JS framework to develop and package the exactly same code and UI into Web Apps, Native Desktop Apps (Windows, OS X, Linux) and Mobile Apps (iOS, Android, Windows Phone, BlackBerry). Open sourced LGPL3. Featured RAD tool (form builder etc.). The UI looks desktop-, not web-oriented. Actively developed, small community. No presence on GitHub.

18. ZinoUI - simple widgets. The DataTable, for instance, doesn't even support sorting.

19. Wijmo - good-looking commercial widgets, with old (jQuery UI) widgets open-sourced on GitHub (their development stopped in 2013). Developed by ComponentOne, a division of GrapeCity. See Wijmo Complete vs. Open.

20. CxJS - commercial JS framework based on React, Babel and webpack offering form elements, form validation, advanced grid control, navigational elements, tooltips, overlays, charts, routing, layout support, themes, culture dependent formatting and more.

Widgets - Demo Apps - Examples - GitHub

Full-stack frameworks

1. SproutCore - developed by Apple for web applications with native performance, handling large data sets on the client. Powers iCloud.com. Not intended for widgets.

2. Wakanda: aimed at business/enterprise web apps - see What is Wakanda?. Architecture:

   • Wakanda Server (server-side JavaScript (custom engine) + open-source NoSQL database)
   • desktop IDE and WYSIWYG editor for tables, forms, reports

   • Wakanda Application Framework (datasource layer + browser-based interface widgets) that helps with browser and device compatibility across desktop and mobile

     Wakanda is highly integrated, includes a ton of features out of the box, but has a very small GitHub community and SO presence.

3. Servoy - "a cross platform frontend development and deployment environment for SQL databases". Boasts a "full WYSIWIG (What You See Is What You Get) UI designer for HTML5 with built-in data-binding to back-end services", responsive design, support for HTML6 Web Components, Websockets and mobile platforms. Written in Java and generates JavaScript code using various JavaBeans.

4. SmartClient/SmartGWT - mobile and cross-browser HTML5 UI components combined with a Java server. Aimed at building powerful business apps - see demos.

5. Vaadin - full-stack Java/GWT + JavaScript/HTML3 web app framework

6. Backbase - portal software

7. Shiny - front-end library on top R, with visualization, layout and control widgets

8. ZKOSS: Java+jQuery+Bootstrap framework for building enterprise web and mobile apps.

CSS libraries + minimal widgets

These libraries don't implement complex widgets such as tables with sorting/filtering, autocompletes, or trees.

1. Bootstrap

2. Foundation for Apps - responsive front-end framework on top of AngularJS; more of a grid/layout/navigation library

3. UI Kit - similar to Bootstrap, with fewer widgets, but with official off-canvas.

Libraries using HTML Canvas

Using the canvas elements allows for complete control over the UI, and great cross-browser compatibility, but comes at the cost of missing native browser functionality, e.g. page search via Ctrl/Cmd+F.

1. Zebra - demos

No longer developed as of Dec 2014

1. Yahoo! User Interface - YUI, launched in 2005, but no longer maintained by the core contributors - see the announcement, which highlights reasons why large UI widget libraries are perceived as walled gardens that developers don't want to be locked into.
2. echo3, GitHub. Supports writing either server-side Java applications that don't require developer knowledge of HTML, HTTP, or JavaScript, or client-side JavaScript-based applications do not require a server, but can communicate with one via AJAX. Last update: July 2013.

I've been trying to do something very similar but not using the nodes. However, my xml structure is a little different.

You have it like this:

<Metrics>
    <Metric id="TransactionCleanupThread.RefundOldTrans" type="timer" ...>

If it were like this instead:

<Metrics>
    <Metric>
        <id>TransactionCleanupThread.RefundOldTrans</id>
        <type>timer</type>
        .
        .
        .

Then you could simply use this SQL statement.

SELECT
    Sqm.SqmId,
    Data.value('(/Sqm/Metrics/Metric/id)[1]', 'varchar(max)') as id,
    Data.value('(/Sqm/Metrics/Metric/type)[1]', 'varchar(max)') AS type,
    Data.value('(/Sqm/Metrics/Metric/unit)[1]', 'varchar(max)') AS unit,
    Data.value('(/Sqm/Metrics/Metric/sum)[1]', 'varchar(max)') AS sum,
    Data.value('(/Sqm/Metrics/Metric/count)[1]', 'varchar(max)') AS count,
    Data.value('(/Sqm/Metrics/Metric/minValue)[1]', 'varchar(max)') AS minValue,
    Data.value('(/Sqm/Metrics/Metric/maxValue)[1]', 'varchar(max)') AS maxValue,
    Data.value('(/Sqm/Metrics/Metric/stdDeviation)[1]', 'varchar(max)') AS stdDeviation,
FROM Sqm

To me this is much less confusing than using the outer apply or cross apply.

I hope this helps someone else looking for a simpler solution!

You can adjust the plot margins with plot.margin in theme() and then move your axis labels and title with the vjust argument of element_text(). For example :

library(ggplot2)
library(grid)
qplot(rnorm(100)) +
    ggtitle("Title") +
    theme(axis.title.x=element_text(vjust=-2)) +
    theme(axis.title.y=element_text(angle=90, vjust=-0.5)) +
    theme(plot.title=element_text(size=15, vjust=3)) +
    theme(plot.margin = unit(c(1,1,1,1), "cm"))

will give you something like this :

If you want more informations about the different theme() parameters and their arguments, you can just enter ?theme at the R prompt.

Starting OracleServiceHari where 'HARI' is the SID, worked for me.

Others facing same problem may check status of the service.

Yes, I think performance-wise you might find a difference as bitwise left and right shift operations can be performed with a complexity of o(1) with a huge data set.

For example, calculating the power of 2 ^ n:

int value = 1;
while (exponent<n)
    {
       // Print out current power of 2
        value = value *2; // Equivalent machine level left shift bit wise operation
        exponent++;
         }
    }

Similar code with a bitwise left shift operation would be like:

value = 1 << n;

Moreover, performing a bit-wise operation is like exacting a replica of user level mathematical operations (which is the final machine level instructions processed by the microcontroller and processor).

I had the exact same situation. It was caused by not having a PropertySourcesPlaceholderConfigurer in the Spring context, which resolves values against the @Value annotation inside of classes.

Include a property placeholder to solve the problem, no need to use Spring expressions for integers (the property file does not have to exist if you use ignore-resource-not-found="true"):

<context:property-placeholder location="/path/to/my/app.properties"
    ignore-resource-not-found="true" />

Of course it depends on what kind of programmer you want to be, or better what kind of programmer your employers want you to be. I think calculus and algebra are essentials, statistic and linear programming is indeed a good tool to have in your briefcase, maybe analysis (derivative, integrals, functions...) could be done without. But if you want to know how things work skin-deep (electronics, for example, or some non trivial algorhytms) "advanced" math is something you'd better not go without anywhere.

In Python 3, they made the / operator do a floating-point division, and added the // operator to do integer division (i.e., quotient without remainder); whereas in Python 2, the / operator was simply integer division, unless one of the operands was already a floating point number.

In Python 2.X:

>>> 10/3
3
>>> # To get a floating point number from integer division:
>>> 10.0/3
3.3333333333333335
>>> float(10)/3
3.3333333333333335

In Python 3:

>>> 10/3
3.3333333333333335
>>> 10//3
3

For further reference, see PEP238.

I arrived here like most people with this same issue, and left shocked that none of the answer even remotely worked.

For anyone interested, here is the actual solution:

... //rest of options
width: '100%',
height: '350',
chartArea:{
    left:5,
    top: 20,
    width: '100%',
    height: '350',
}
... //rest of options

The key here has nothing to do with the "left" or "top" values. But rather that the:

Dimensions of both the chart and chart-area are SET and set to the SAME VALUE

As an amendment to my answer. The above will indeed solve the "excessive" padding/margin/whitespace problem. However, if you wish to include axes labels and/or a legend you will need to reduce the height & width of the chart area so something slightly below the outer width/height. This will "tell" the chart API that there is sufficient room to display these properties. Otherwise it will happily exclude them.

Here is your solution for the problem,

$letter = array();
for ($i = 'A'; $i !== 'ZZ'; $i++){
        if(ord($i) % 2 != 0)
           $letter[] .= $i;
}
print_r($letter);

You need to get the ASCII value for that character which will solve your problem.

Here is ord doc and working code.

For your requirement, you can do like this,

for ($i = 'A'; $i !== 'ZZ'; ord($i)+$x){
  $letter[] .= $i;
}
print_r($letter);

Here set $x as per your requirement.

The adb tool can be found in sdk/platform-tools/

If you don't see this directory in your SDK, launch the SDK Manager and install "Android SDK Platform-tools"

Also update your PATH environment variable to include the platform-tools/ directory, so you can execute adb from any location.

Use get(0) instead of html(). In other words, replace

doc.fromHTML($('#htmlTableId').html(), 15, 15, {
    'width': 170,'elementHandlers': specialElementHandlers
});

with

doc.fromHTML($('#htmlTableId').get(0), 15, 15, {
    'width': 170,'elementHandlers': specialElementHandlers
});

To make an Ajax request using jQuery you can do this by the following code.

HTML:

<form id="foo">
    <label for="bar">A bar</label>
    <input id="bar" name="bar" type="text" value="" />
    <input type="submit" value="Send" />
</form>

<!-- The result of the search will be rendered inside this div -->
<div id="result"></div>

JavaScript:

Method 1

 /* Get from elements values */
 var values = $(this).serialize();

 $.ajax({
        url: "test.php",
        type: "post",
        data: values ,
        success: function (response) {

           // You will get response from your PHP page (what you echo or print)
        },
        error: function(jqXHR, textStatus, errorThrown) {
           console.log(textStatus, errorThrown);
        }
    });

Method 2

/* Attach a submit handler to the form */
$("#foo").submit(function(event) {
    var ajaxRequest;

    /* Stop form from submitting normally */
    event.preventDefault();

    /* Clear result div*/
    $("#result").html('');

    /* Get from elements values */
    var values = $(this).serialize();

    /* Send the data using post and put the results in a div. */
    /* I am not aborting the previous request, because it's an
       asynchronous request, meaning once it's sent it's out
       there. But in case you want to abort it you can do it
       by abort(). jQuery Ajax methods return an XMLHttpRequest
       object, so you can just use abort(). */
       ajaxRequest= $.ajax({
            url: "test.php",
            type: "post",
            data: values
        });

    /*  Request can be aborted by ajaxRequest.abort() */

    ajaxRequest.done(function (response, textStatus, jqXHR){

         // Show successfully for submit message
         $("#result").html('Submitted successfully');
    });

    /* On failure of request this function will be called  */
    ajaxRequest.fail(function (){

        // Show error
        $("#result").html('There is error while submit');
    });

The .success(), .error(), and .complete() callbacks are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use .done(), .fail(), and .always() instead.

MDN: abort() . If the request has been sent already, this method will abort the request.

So we have successfully send an Ajax request, and now it's time to grab data to server.

PHP

As we make a POST request in an Ajax call (type: "post"), we can now grab data using either $_REQUEST or $_POST:

  $bar = $_POST['bar']

You can also see what you get in the POST request by simply either. BTW, make sure that $_POST is set. Otherwise you will get an error.

var_dump($_POST);
// Or
print_r($_POST);

And you are inserting a value into the database. Make sure you are sensitizing or escaping All requests (whether you made a GET or POST) properly before making the query. The best would be using prepared statements.

And if you want to return any data back to the page, you can do it by just echoing that data like below.

// 1. Without JSON
   echo "Hello, this is one"

// 2. By JSON. Then here is where I want to send a value back to the success of the Ajax below
echo json_encode(array('returned_val' => 'yoho'));

And then you can get it like:

 ajaxRequest.done(function (response){
    alert(response);
 });

There are a couple of shorthand methods. You can use the below code. It does the same work.

var ajaxRequest= $.post("test.php", values, function(data) {
  alert(data);
})
  .fail(function() {
    alert("error");
  })
  .always(function() {
    alert("finished");
});

That is lonefy.vscode-js-css-html-formatter to blame. Disable it, and install HookyQR.beautify.

Now on save your tabs wouldn't be converted.

Instead of this:

CheckboxList1.Items[i].value;

Try This:

CheckboxList1.Items[i].ToString();

It worked for me :)

The use of transition: none seems to be supported (with a specific adjustment for Opera) given the following HTML:

<a href="#" class="transition">Content</a>
<a href="#" class="transition">Content</a>
<a href="#" class="noTransition">Content</a>
<a href="#" class="transition">Content</a>

...and CSS:

a {
    color: #f90;
    -webkit-transition:color 0.8s ease-in, background-color 0.1s ease-in ;  
    -moz-transition:color 0.8s ease-in, background-color 0.1s ease-in;  
    -o-transition:color 0.8s ease-in, background-color 0.1s ease-in;  
    transition:color 0.8s ease-in, background-color 0.1s ease-in; 
}
a:hover {
    color: #f00;
    -webkit-transition:color 0.8s ease-in, background-color 0.1s ease-in ;  
    -moz-transition:color 0.8s ease-in, background-color 0.1s ease-in;  
    -o-transition:color 0.8s ease-in, background-color 0.1s ease-in;  
    transition:color 0.8s ease-in, background-color 0.1s ease-in; 
}
a.noTransition {
    -moz-transition: none;
    -webkit-transition: none;
    -o-transition: color 0 ease-in;
    transition: none;
}

JS Fiddle demo.

Tested with Chromium 12, Opera 11.x and Firefox 5 on Ubuntu 11.04.

The specific adaptation to Opera is the use of -o-transition: color 0 ease-in; which targets the same property as specified in the other transition rules, but sets the transition time to 0, which effectively prevents the transition from being noticeable. The use of the a.noTransition selector is simply to provide a specific selector for the elements without transitions.

Edited to note that @Frédéric Hamidi's answer, using all (for Opera, at least) is far more concise than listing out each individual property-name that you don't want to have transition.

Updated JS Fiddle demo, showing the use of all in Opera: -o-transition: all 0 none, following self-deletion of @Frédéric's answer.

An alternative - which may work for you depending on what you're trying to do - is to have the HTML in place and then use the CSS to show or hide it depending on the class of a parent element.

Use jQuery append()

There are a lot of answers here, but none of them suited my needs. I wanted an actual answer to the asker's #1 question. How do I know when an image is updated on hub.docker.com?

The below script can be run daily. On first run, it gets a baseline of the tags and update dates from the HUB registry and saves them locally. From then out, every time it is run it checks the registry for new tags and update dates. Since this changes every time a new image exists, it tells us if the base image has changed. Here is the script:

#!/bin/bash

DATAPATH='/data/docker/updater/data'

if [ ! -d "${DATAPATH}" ]; then
        mkdir "${DATAPATH}";
fi
IMAGES=$(docker ps --format "{{.Image}}")
for IMAGE in $IMAGES; do
        ORIGIMAGE=${IMAGE}
        if [[ "$IMAGE" != *\/* ]]; then
                IMAGE=library/${IMAGE}
        fi
        IMAGE=${IMAGE%%:*}
        echo "Checking ${IMAGE}"
        PARSED=${IMAGE//\//.}
        if [ ! -f "${DATAPATH}/${PARSED}" ]; then
                # File doesn't exist yet, make baseline
                echo "Setting baseline for ${IMAGE}"
                curl -s "https://registry.hub.docker.com/v2/repositories/${IMAGE}/tags/" > "${DATAPATH}/${PARSED}"
        else
                # File does exist, do a compare
                NEW=$(curl -s "https://registry.hub.docker.com/v2/repositories/${IMAGE}/tags/")
                OLD=$(cat "${DATAPATH}/${PARSED}")
                if [[ "${VAR1}" == "${VAR2}" ]]; then
                        echo "Image ${IMAGE} is up to date";
                else
                        echo ${NEW} > "${DATAPATH}/${PARSED}"
                        echo "Image ${IMAGE} needs to be updated";
                        H=`hostname`
                        ssh -i /data/keys/<KEYFILE> <USER>@<REMOTEHOST>.com "{ echo \"MAIL FROM: root@${H}\"; echo \"RCPT TO: <USER>@<EMAILHOST>.com\"; echo \"DATA\"; echo \"Subject: ${H} - ${IMAGE} needs update\"; echo \"\"; echo -e \"\n${IMAGE} needs update.\n\ndocker pull ${ORIGIMAGE}\"; echo \"\"; echo \".\"; echo \"quit\"; sleep 1; } | telnet <SMTPHOST> 25"
                fi

        fi
done;

You will want to alter the DATAPATH variable at the top, and alter the email notification command at the end to suit your needs. For me, I have it SSH into a server on another network where my SMTP is located. But you could easily use the mail command, too.

Now, you also want to check for updated packages inside the containers themselves. This is actually probably more effective than doing a "pull" once your containers are working. Here's the script to pull that off:

#!/bin/bash


function needsUpdates() {
        RESULT=$(docker exec ${1} bash -c ' \
                if [[ -f /etc/apt/sources.list ]]; then \
                grep security /etc/apt/sources.list > /tmp/security.list; \
                apt-get update > /dev/null; \
                apt-get upgrade -oDir::Etc::Sourcelist=/tmp/security.list -s; \
                fi; \
                ')
        RESULT=$(echo $RESULT)
        GOODRESULT="Reading package lists... Building dependency tree... Reading state information... Calculating upgrade... 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded."
        if [[ "${RESULT}" != "" ]] && [[ "${RESULT}" != "${GOODRESULT}" ]]; then
                return 0
        else
                return 1
        fi
}

function sendEmail() {
        echo "Container ${1} needs security updates";
        H=`hostname`
        ssh -i /data/keys/<KEYFILE> <USRER>@<REMOTEHOST>.com "{ echo \"MAIL FROM: root@${H}\"; echo \"RCPT TO: <USER>@<EMAILHOST>.com\"; echo \"DATA\"; echo \"Subject: ${H} - ${1} container needs security update\"; echo \"\"; echo -e \"\n${1} container needs update.\n\n\"; echo -e \"docker exec ${1} bash -c 'grep security /etc/apt/sources.list > /tmp/security.list; apt-get update > /dev/null; apt-get upgrade -oDir::Etc::Sourcelist=/tmp/security.list -s'\n\n\"; echo \"Remove the -s to run the update\"; echo \"\"; echo \".\"; echo \"quit\"; sleep 1; } | telnet <SMTPHOST> 25"
}

CONTAINERS=$(docker ps --format "{{.Names}}")
for CONTAINER in $CONTAINERS; do
        echo "Checking ${CONTAINER}"
        if needsUpdates $CONTAINER; then
                sendEmail $CONTAINER
        fi
done

In malfaux's answer '^' and '$' has been used to detect the beginning and the end of the text.
These are usually used to detect the beginning and the end of a line.
However this may be the correct way in this case.
But if you wish to match an exact word the more elegant way is to use '\b'. In this case following pattern will match the exact phrase'123456'.

/\b123456\b/

you can do this

while 2 in x:   
    x.remove(2)

better solution with list comprehension

x = [ i for i in x if i!=2 ]

Updated with feedback from Alan Moore

In PCRE and similar variants, you can actually create a regex that matches any line not containing a value:

^(?:(?!Andrea).)*$

This is called a tempered greedy token. The downside is that it doesn't perform well.

Object.toparams = function ObjecttoParams(obj) 
{
  var p = [];
  for (var key in obj) 
  {
    p.push(key + '=' + encodeURIComponent(obj[key]));
  }
  return p.join('&');
};

In your Manifest you need to reference the name of the style that has the text color item inside it. Right now you are just referencing an empty style. So in your theme.xml do only this style:

<style name="Theme" parent="@android:style/TextAppearance">
    <item name="android:textColor">#ffffffff</item>
</style>

And keep you reference to in the Manifest the same (android:theme="@style/Theme")

EDIT:

theme.xml:

<style name="MyTheme" parent="@android:style/TextAppearance">
    <item name="android:textColor">#ffffffff</item>
    <item name="android:textSize">12dp</item>
</style>

Manifest:

<application
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@style/MyTheme">

Notice I combine the text color and size into the same style. Also, I changed the name of the theme to MyTheme and am now referencing that in the Manifest. And I changed to @android:style/TextAppearance for the parent value.

function removeParam($url, $param) {
    $url = preg_replace('/(&|\?)'.preg_quote($param).'=[^&]*$/', '', $url);
    $url = preg_replace('/(&|\?)'.preg_quote($param).'=[^&]*&/', '$1', $url);
    return $url;
}

I know I am late to the party, but how about this?

const char* dayNames[] = { [Sunday] = "Sunday", [Monday] = "Monday", /*and so on*/ };
printf("%s", dayNames[Sunday]); // prints "Sunday"

This way, you do not have to manually keep the enum and the char* array in sync. If you are like me, chances are that you will later change the enum, and the char* array will print invalid strings. This may not be a feature universally supported. But afaik, most of the mordern day C compilers support this designated initialier style.

You can read more about designated initializers here.

You Probably Don't Need Moment.js Anymore

Moment is great time manipulation library but it's considered as a legacy project, and the team is recommending to use other libraries.

date-fns is one of the best lightweight libraries, it's modular, so you can pick the functions you need and reduce bundle size (issue & statement).

Another common argument against using Moment in modern applications is its size. Moment doesn't work well with modern "tree shaking" algorithms, so it tends to increase the size of web application bundles.

import { format } from 'date-fns' // 21K (gzipped: 5.8K)
import moment from 'moment' // 292.3K (gzipped: 71.6K)

Format date with date-fns:

// moment.js
moment().format('MM/DD/YYYY');
// => "12/18/2020"

// date-fns
import { format } from 'date-fns'
format(new Date(), 'MM/dd/yyyy');
// => "12/18/2020"

More on cheat sheet with the list of functions which you can use to replace moment.js: You-Dont-Need-Momentjs

Don't know much VB.NET syntax but here's and idea

Dim source As New Bitmap("C:\image.png") 
Dim target As New Bitmap(size.Width, size.Height, PixelFormat.Format24bppRgb)

Using graphics As Graphics = Graphics.FromImage(target)
    graphics.DrawImage(source, new Size(48, 48)) 
End Using

This post pertains to R proxy issues on *nix. You should know that R has many libraries/methods to fetch data over internet.

For 'curl', 'libcurl', 'wget' etc, just do the following:

1. Open a terminal. Type the following command:

   sudo gedit /etc/R/Renviron.site
   

2. Enter the following lines:

   http_proxy='http://username:[email protected]:port/'
   https_proxy='https://username:[email protected]:port/'
   

   Replace username, password, abc.com, xyz.com and port with these settings specific to your network.

3. Quit R and launch again.

This should solve your problem with 'libcurl' and 'curl' method. However, I have not tried it with 'httr'. One way to do that with 'httr' only for that session is as follows:

library(httr)
set_config(use_proxy(url="abc.com",port=8080, username="username", password="password"))

You need to substitute settings specific to your n/w in relevant fields.

To populate the column during insert, use a DEFAULT value:

CREATE TABLE users (
  id serial not null,
  firstname varchar(100),
  middlename varchar(100),
  lastname varchar(100),
  email varchar(200),
  timestamp timestamp default current_timestamp
)

Note that the value for that column can explicitly be overwritten by supplying a value in the INSERT statement. If you want to prevent that you do need a trigger.

You also need a trigger if you need to update that column whenever the row is updated (as mentioned by E.J. Brennan)

Note that using reserved words for column names is usually not a good idea. You should find a different name than timestamp

Open your logCat when trying to install the app. Set it to "No Filters". Search for "InstallAppProgress" package identifier. If the install fails you should see an "Installation error code". In my case it was

D/InstallAppProgress: Installation error code: -7

From here you can use this link to find information about your specific error code.

Looking all answers I compose universal function what working on all PHP versions.

if(!function_exists('date_between')) :
    function date_between($date_start, $date_end)
    {
        if(!$date_start || !$date_end) return 0;

        if( class_exists('DateTime') )
        {
            $date_start = new DateTime( $date_start );
            $date_end   = new DateTime( $date_end );
            return $date_end->diff($date_start)->format('%a');
        }
        else
        {           
            return abs( round( ( strtotime($date_start) - strtotime($date_end) ) / 86400 ) );
        }
    }
endif;

In the general, I use 'DateTime' to find days between 2 dates. But if in the some reason, some server setup not have 'DateTime' enabled, it will use simple (but not safe) calculation with 'strtotime()'.

You print the queryset's query attribute.

>>> queryset = MyModel.objects.all()
>>> print(queryset.query)
SELECT "myapp_mymodel"."id", ... FROM "myapp_mymodel"

Compact all collections in current database

db.getCollectionNames().forEach(function (collectionName) {
    print('Compacting: ' + collectionName);
    db.runCommand({ compact: collectionName });
});

I found that the accepted answer worked for a fixed width, but not a fixed height. For a fixed height, it would just increase the width to fit everything on one line, unless there was a line break in the text.

The width function calls the height function multiple times, but it is a quick calculation and I didn't notice performance issues using the function in the rows of a UITable.

extension String {

    public func height(withConstrainedWidth width: CGFloat, font: UIFont) -> CGFloat {
        let constraintRect = CGSize(width: width, height: .greatestFiniteMagnitude)
        let boundingBox = self.boundingRect(with: constraintRect, options: .usesLineFragmentOrigin, attributes: [.font : font], context: nil)

        return ceil(boundingBox.height)
    }

    public func width(withConstrainedHeight height: CGFloat, font: UIFont, minimumTextWrapWidth:CGFloat) -> CGFloat {

        var textWidth:CGFloat = minimumTextWrapWidth
        let incrementWidth:CGFloat = minimumTextWrapWidth * 0.1
        var textHeight:CGFloat = self.height(withConstrainedWidth: textWidth, font: font)

        //Increase width by 10% of minimumTextWrapWidth until minimum width found that makes the text fit within the specified height
        while textHeight > height {
            textWidth += incrementWidth
            textHeight = self.height(withConstrainedWidth: textWidth, font: font)
        }
        return ceil(textWidth)
    }
}

This sometimes does not work if Eclipse is on one of those strange default windows paths (e.g. c:/Program files (86)/Eclipse).

In that case, do as above, then move the lombok jar to a cleaner path without spaces and braces (e.g. c:\lombok\lombok.jar) and modify eclipse.ini accordingly.

I think what you want is a different content mode. Try using UIViewContentModeScaleToFill. This will scale the content to fit the size of ur UIImageView by changing the aspect ratio of the content if necessary.

Have a look to the content mode section on the official doc to get a better idea of the different content mode available (it is illustrated with images).

There is another way to pristine form that is by sending form into the controller. For example:-

In view:-

<form name="myForm" ng-submit="addUser(myForm)" novalidate>
    <input type="text" ng-mode="user.name"/>
     <span style="color:red" ng-show="myForm.name.$dirty && myForm.name.$invalid">
      <span ng-show="myForm.name.$error.required">Name is required.</span>
    </span>

    <button ng-disabled="myForm.$invalid">Add User</button>
</form>

In Controller:-

$scope.addUser = function(myForm) {
       myForm.$setPristine();
};

This works using java.util.Scanner and will take multiple "enter" keystrokes:

    Scanner scanner = new Scanner(System.in);
    String readString = scanner.nextLine();
    while(readString!=null) {
        System.out.println(readString);

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }
    }

To break it down:

Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();

These lines initialize a new Scanner that is reading from the standard input stream (the keyboard) and reads a single line from it.

    while(readString!=null) {
        System.out.println(readString);

While the scanner is still returning non-null data, print each line to the screen.

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

If the "enter" (or return, or whatever) key is supplied by the input, the nextLine() method will return an empty string; by checking to see if the string is empty, we can determine whether that key was pressed. Here the text Read Enter Key is printed, but you could perform whatever action you want here.

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }

Finally, after printing the content and/or doing something when the "enter" key is pressed, we check to see if the scanner has another line; for the standard input stream, this method will "block" until either the stream is closed, the execution of the program ends, or further input is supplied.

Try this :

SELECT CONVERT(varchar(2), GETDATE(), 101)

if your using php for the backend maybe you can use this code.

// Validate image file size
if (($_FILES["file-input"]["size"] > 2000000)) {
    $msg = "Image File Size is Greater than 2MB.";
    header("Location: ../product.php?error=$msg");
    exit();
}  

You can justify the navbar contents by using:

@media (min-width: 768px){
  .navbar-nav{
     margin: 0 auto;
     display: table;
     table-layout: fixed;
     float: none;
  }
}

Good luck!

From a Windows Server OS execute the following command for a dump of the entire Active Director:

csvde -f test.csv

This command is very broad and will give you more than necessary information. To constrain the records to only user records, you would instead want:

csvde -f test.csv -r objectClass=user 

You can further restrict the command to give you only the fields you need relevant to the search requested such as:

csvde -f test.csv -r objectClass=user -l DN, sAMAccountName, department, memberOf

If you have an Exchange server and each user associated with a live person has a mailbox (as opposed to generic accounts for kiosk / lab workstations) you can use mailNickname in place of sAMAccountName.

You can use the minDate property, like this:

$("input.DateFrom").datepicker({
    changeMonth: true, 
    changeYear: true, 
    dateFormat: 'yy-mm-dd',
    minDate: 0, // 0 days offset = today
    maxDate: 'today',
    onSelect: function(dateText) {
        $sD = new Date(dateText);
        $("input#DateTo").datepicker('option', 'minDate', min);
    }
});

You can also specify a date, like this:

minDate: new Date(), // = today
