To add to the accepted answer, I had a similar issue and solved it using a similar approach with the contrived example below. In this case I needed to log some parameters on componentWillUnmount and as described in the original question I didn't want it to log every time the params changed.

const componentWillUnmount = useRef(false)

// This is componentWillUnmount
useEffect(() => {
    return () => {
        componentWillUnmount.current = true
    }
}, [])

useEffect(() => {
    return () => {
        // This line only evaluates to true after the componentWillUnmount happens 
        if (componentWillUnmount.current) {
            console.log(params)
        }
    }

}, [params]) // This dependency guarantees that when the componentWillUnmount fires it will log the latest params

axios signature for post is axios.post(url[, data[, config]]). So you want to send params object within the third argument:

.post(`/mails/users/sendVerificationMail`, null, { params: {
  mail,
  firstname
}})
.then(response => response.status)
.catch(err => console.warn(err));

This will POST an empty body with the two query params:

POST http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName

i think this can be as simple let as assume that you are going to pass multiple parameters to you action as you read up there actions accept only two parameters context and payload which is your data you want to pass in action so let take an example

Setting up Action

instead of

actions: {
        authenticate: ({ commit }, token, expiration) => commit('authenticate', token, expiration)
    }

do

actions: {
        authenticate: ({ commit }, {token, expiration}) => commit('authenticate', token, expiration)
    }

Calling (dispatching) Action

instead of

this.$store.dispatch({
                  type: 'authenticate',
                  token: response.body.access_token,
                  expiration: response.body.expires_in + Date.now()
              })

do

this.$store.dispatch('authenticate',{
                  token: response.body.access_token,
                  expiration: response.body.expires_in + Date.now()
              })

hope this gonna help

Angular will automatically update a component when it detects a variable change .

So all you have to do for it to "refresh" is ensure that the header has a reference to the new data. This could be via a subscription within header.component.ts or via an @Input variable...

an example...

main.html

<app-header [header-data]="headerData"></app-header>

main.component.ts

public headerData:int = 0;

ngOnInit(){
    setInterval(()=>{this.headerData++;}, 250);
}

header.html

<p>{{data}}</p>

header.ts

@Input('header-data') data;

In the above example, the header will recieve the new data every 250ms and thus update the component.

For more information about Angular's lifecycle hooks, see: https://angular.io/guide/lifecycle-hooks

This one I found simple solutions:

row = myArray.map((cell, i) => {

    if (i == myArray.length - 1) {
      return <div> Test Data 1</div>;
    }
    return <div> Test Data 2</div>;
  });

Run ssh-add on the client machine, that will add the SSH key to the agent.

Confirm with ssh-add -l (again on the client) that it was indeed added.

I would also use navigation.navigate. If someone has the same problem and also uses nested navigators, this is how it would work:

onPress={() =>
        navigation.navigate('MyStackScreen', {
          // Passing params to NESTED navigator screen:
          screen: 'goToScreenA',
          params: { Data: data.item },
        })
      }

You shouldn't use ${varName} when you're outside of strings, you should just use varName. Inside strings you use it like this; echo "this is a string ${someVariable}";. Infact you can place an general java expression inside of ${...}; echo "this is a string ${func(arg1, arg2)}.

I was trying to call setErrors() inside a ngModelChange handler in a template form. It did not work until I waited one tick with setTimeout():

template:

<input type="password" [(ngModel)]="user.password" class="form-control" 
 id="password" name="password" required (ngModelChange)="checkPasswords()">

<input type="password" [(ngModel)]="pwConfirm" class="form-control"
 id="pwConfirm" name="pwConfirm" required (ngModelChange)="checkPasswords()"
 #pwConfirmModel="ngModel">

<div [hidden]="pwConfirmModel.valid || pwConfirmModel.pristine" class="alert-danger">
   Passwords do not match
</div>

component:

@ViewChild('pwConfirmModel') pwConfirmModel: NgModel;

checkPasswords() {
  if (this.pwConfirm.length >= this.user.password.length &&
      this.pwConfirm !== this.user.password) {
    console.log('passwords do not match');
    // setErrors() must be called after change detection runs
    setTimeout(() => this.pwConfirmModel.control.setErrors({'nomatch': true}) );
  } else {
    // to clear the error, we don't have to wait
    this.pwConfirmModel.control.setErrors(null);
  }
}

Gotchas like this are making me prefer reactive forms.

I guess you are using an old version of hibernate. You can download the latest version, 5.2, from here.

I was also looking for some answer. Here all answers are quite good, but none of them give answers how we can use it if user starts application after opening it back. (I meant to say using cookie together).

No need to create even different privateRoute Component. Below is my code

    import React, { Component }  from 'react';
    import { Route, Switch, BrowserRouter, Redirect } from 'react-router-dom';
    import { Provider } from 'react-redux';
    import store from './stores';
    import requireAuth from './components/authentication/authComponent'
    import SearchComponent from './components/search/searchComponent'
    import LoginComponent from './components/login/loginComponent'
    import ExampleContainer from './containers/ExampleContainer'
    class App extends Component {
    state = {
     auth: true
    }


   componentDidMount() {
     if ( ! Cookies.get('auth')) {
       this.setState({auth:false });
     }
    }
    render() {
     return (
      <Provider store={store}>
       <BrowserRouter>
        <Switch>
         <Route exact path="/searchComponent" component={requireAuth(SearchComponent)} />
         <Route exact path="/login" component={LoginComponent} />
         <Route exact path="/" component={requireAuth(ExampleContainer)} />
         {!this.state.auth &&  <Redirect push to="/login"/> }
        </Switch>
       </BrowserRouter>
      </Provider>);
      }
     }
    }
    export default App;

And here is authComponent

import React  from 'react';
import { withRouter } from 'react-router';
import * as Cookie from "js-cookie";
export default function requireAuth(Component) {
class AuthenticatedComponent extends React.Component {
 constructor(props) {
  super(props);
  this.state = {
   auth: Cookie.get('auth')
  }
 }
 componentDidMount() {
  this.checkAuth();
 }
 checkAuth() {
  const location = this.props.location;
  const redirect = location.pathname + location.search;
  if ( ! Cookie.get('auth')) {
   this.props.history.push(`/login?redirect=${redirect}`);
  }
 }
render() {
  return Cookie.get('auth')
   ? <Component { ...this.props } />
   : null;
  }
 }
 return  withRouter(AuthenticatedComponent)
}

Below I have written blog, you can get more depth explanation there as well.

Create Protected routes in ReactJS

If you want to call other api routes in the future and keep your token in the store then try using redux middleware.

The middleware could listen for the an api action and dispatch api requests through axios accordingly.

Here is a very basic example:

actions/api.js

export const CALL_API = 'CALL_API';

function onSuccess(payload) {
  return {
    type: 'SUCCESS',
    payload
  };
}

function onError(payload) {
  return {
    type: 'ERROR',
    payload,
    error: true
  };
}

export function apiLogin(credentials) {
  return {
    onSuccess,
    onError,
    type: CALL_API,
    params: { ...credentials },
    method: 'post',
    url: 'login'
  };
}

middleware/api.js

import axios from 'axios';
import { CALL_API } from '../actions/api';

export default ({ getState, dispatch }) => next => async action => {
  // Ignore anything that's not calling the api
  if (action.type !== CALL_API) {
    return next(action);
  }

  // Grab the token from state
  const { token } = getState().session;

  // Format the request and attach the token.
  const { method, onSuccess, onError, params, url } = action;

  const defaultOptions = {
    headers: {
      Authorization: token ? `Token ${token}` : '',
    }
  };

  const options = {
    ...defaultOptions,
    ...params
  };

  try {
    const response = await axios[method](url, options);
    dispatch(onSuccess(response.data));
  } catch (error) {
    dispatch(onError(error.data));
  }

  return next(action);
};

I got this error resolved by doing 2 things in chrome browser:

1. Pressed Ctrl + Shift + Delete and cleared all browsing data from beginning.
2. Go to Chrome's : Settings ->Advanced Settings -> Open proxy settings -> Internet Properties then Go to the Content window and click on the Clear SSL State Button.

This site has this information and other options as well : https://www.thesslstore.com/blog/fix-err-ssl-protocol-error/

For me, in Ubuntu 18.04. I needed to chown inside ~/.config/composer/

E.g.

sudo chown -R $USER ~/.config/composer

Then global commands work.

update of @Vladimir Tolstikov's answer

Create a Child Component that use ngOnChanges.

ChildComponent.ts::

import { Component, OnChanges, Input } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({
  selector: 'child',
  templateUrl: 'child.component.html',
})

export class ChildComponent implements OnChanges {
  @Input() child_id;

  constructor(private route: ActivatedRoute) { }

  ngOnChanges() {
    // create header using child_id
    console.log(this.child_id);
  }
}

now use it in MasterComponent's template and pass data to ChildComponent like:

<child [child_id]="child_id"></child>

When using <abc [(bar)]="foo"/> syntax on angular.

This translates to: <abc [bar]="foo" (barChange)="foo = $event" />

Which means your component should have:

@Input() bar;
@Output() barChange = new EventEmitter();

I have put something like this in my Controller class and it worked:

IdentityUser user = await userManager.FindByNameAsync(HttpContext.User.Identity.Name);

where userManager is an instance of Microsoft.AspNetCore.Identity.UserManager class (with all weird setup that goes with it).

For me it was caused by having different versions of .Net Core installed. I matched my dev and production server and it worked.

There's no need to use onAuthStateChanged() function in this scenario.

You can easily detect if the user is logged or not by executing:

var user = firebase.auth().currentUser;

For those who face the "returning null" issue, it's just because you are not waiting for the firebase call to complete.

Let's suppose you perform the login action on Page A and then you invoke Page B, on Page B you can call the following JS code to test the expected behavior:

  var config = {
    apiKey: "....",
    authDomain: "...",
    databaseURL: "...",
    projectId: "..",
    storageBucket: "..",
    messagingSenderId: ".."
  };
  firebase.initializeApp(config);

    $( document ).ready(function() {
        console.log( "testing.." );
        var user = firebase.auth().currentUser;
        console.log(user);
    });

If the user is logged then "var user" will contain the expected JSON payload, if not, then it will be just "null"

And that's all you need.

The onTokenRefresh() method is going to be called whenever a new token is generated. Upon app install, it will be generated immediately (as you have found to be the case). It will also be called when the token has changed.

According to the FirebaseCloudMessaging guide:

You can target notifications to a single, specific device. On initial startup of your app, the FCM SDK generates a registration token for the client app instance.

Source Link: https://firebase.google.com/docs/notifications/android/console-device#access_the_registration_token

This means that the token registration is per app. It sounds like you would like to utilize the token after a user is logged in. What I would suggest is that you save the token in the onTokenRefresh() method to internal storage or shared preferences. Then, retrieve the token from storage after a user logs in and register the token with your server as needed.

If you would like to manually force the onTokenRefresh(), you can create an IntentService and delete the token instance. Then, when you call getToken, the onTokenRefresh() method will be called again.

Example Code:

public class DeleteTokenService extends IntentService
{
    public static final String TAG = DeleteTokenService.class.getSimpleName();

    public DeleteTokenService()
    {
        super(TAG);
    }

    @Override
    protected void onHandleIntent(Intent intent)
    {
        try
        {
            // Check for current token
            String originalToken = getTokenFromPrefs();
            Log.d(TAG, "Token before deletion: " + originalToken);

            // Resets Instance ID and revokes all tokens.
            FirebaseInstanceId.getInstance().deleteInstanceId();

            // Clear current saved token
            saveTokenToPrefs("");

            // Check for success of empty token
            String tokenCheck = getTokenFromPrefs();
            Log.d(TAG, "Token deleted. Proof: " + tokenCheck);

            // Now manually call onTokenRefresh()
            Log.d(TAG, "Getting new token");
            FirebaseInstanceId.getInstance().getToken();
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }

    private void saveTokenToPrefs(String _token)
    {
        // Access Shared Preferences
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
        SharedPreferences.Editor editor = preferences.edit();

        // Save to SharedPreferences
        editor.putString("registration_id", _token);
        editor.apply();
    }

    private String getTokenFromPrefs()
    {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
        return preferences.getString("registration_id", null);
    }
}

EDIT

FirebaseInstanceIdService

public class FirebaseInstanceIdService extends Service

This class is deprecated. In favour of overriding onNewToken in FirebaseMessagingService. Once that has been implemented, this service can be safely removed.

onTokenRefresh() is deprecated. Use onNewToken() in MyFirebaseMessagingService

public class MyFirebaseMessagingService extends FirebaseMessagingService {

@Override
public void onNewToken(String s) {
    super.onNewToken(s);
    Log.e("NEW_TOKEN",s);
    }

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    }
} 

I faced the same problem but I had still had some debris in my manifest from the old GCM. When I took the following permission out of my manifest it fixed the error. com.google.android.c2dm.permission.RECEIVE

If you open your ide with sudo. You are not going to have this problem.

A similar looking answer was downvoted. But I think I can justify what I'm suggesting here for limited cases.

While it's true that an observable doesn't have a current value, very often it will have an immediately available value. For example with redux / flux / akita stores you may request data from a central store, based on a number of observables and that value will generally be immediately available.

If this is the case then when you subscribe, the value will come back immediately.

So let's say you had a call to a service, and on completion you want to get the latest value of something from your store, that potentially might not emit:

You might try to do this (and you should as much as possible keep things 'inside pipes'):

 serviceCallResponse$.pipe(withLatestFrom(store$.select(x => x.customer)))
                     .subscribe(([ serviceCallResponse, customer] => {

                        // we have serviceCallResponse and customer 
                     });

The problem with this is that it will block until the secondary observable emits a value, which potentially could be never.

I found myself recently needing to evaluate an observable only if a value was immediately available, and more importantly I needed to be able to detect if it wasn't. I ended up doing this:

 serviceCallResponse$.pipe()
                     .subscribe(serviceCallResponse => {

                        // immediately try to subscribe to get the 'available' value
                        // note: immediately unsubscribe afterward to 'cancel' if needed
                        let customer = undefined;

                        // whatever the secondary observable is
                        const secondary$ = store$.select(x => x.customer);

                        // subscribe to it, and assign to closure scope
                        sub = secondary$.pipe(take(1)).subscribe(_customer => customer = _customer);
                        sub.unsubscribe();

                        // if there's a delay or customer isn't available the value won't have been set before we get here
                        if (customer === undefined) 
                        {
                           // handle, or ignore as needed
                           return throwError('Customer was not immediately available');
                        }
                     });

Note that for all of the above I'm using subscribe to get the value (as @Ben discusses). Not using a .value property, even if I had a BehaviorSubject.

You should return the line that redirects

return res.redirect('/UserHomePage');

First off, custom events don't play well with React components natively. So you cant just say <div onMyCustomEvent={something}> in the render function, and have to think around the problem.

Secondly, after taking a peek at the documentation for the library you're using, the event is actually fired on document.body, so even if it did work, your event handler would never trigger.

Instead, inside componentDidMount somewhere in your application, you can listen to nv-enter by adding

document.body.addEventListener('nv-enter', function (event) {
    // logic
});

Then, inside the callback function, hit a function that changes the state of the component, or whatever you want to do.

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

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

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

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

  @Input() newCar: car = {};

  constructor() {}

  ngOnInit(): void {

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

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

If you want a simple true/false value, you can pipe your docker.json to jq.

is_logged_in() {
  cat ~/.docker/config.json | jq -r --arg url "${REPOSITORY_URL}" '.auths | has($url)'
}

if [[ "$(is_logged_in)" == "false" ]]; then
  # do stuff, log in
fi

My Solution in laravel 5.2

{{ Form::open(['route' => ['votes.submit', $video->id],  'method' => 'POST']) }}
    <button type="submit" class="btn btn-primary">
        <span class="glyphicon glyphicon-thumbs-up"></span> Votar
    </button>
{{ Form::close() }}

My Routes File (under middleware)

Route::post('votar/{id}', [
    'as' => 'votes.submit',
    'uses' => 'VotesController@submit'
]);

Route::delete('votar/{id}', [
    'as' => 'votes.destroy',
    'uses' => 'VotesController@destroy'
]);

As of version 3.0.0, you can get the current route by calling:

this.context.router.location.pathname

Sample code is below:

var NavLink = React.createClass({
    contextTypes: {
        router: React.PropTypes.object
    },

    render() {   
        return (
            <Link {...this.props}></Link>
        );
    }
});

This is happening because there is no package cache in the image, you need to run:

apt-get -qq update

before installing packages, and if your command is in a Dockerfile, you'll then need:

apt-get -qq -y install curl

After that install ZSH and GIT Core:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird since sh does not understand the source command. So, you do this to install zsh:

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

and then you change your shell to zsh:

chsh -s `which zsh`

and then restart:

sudo shutdown -r 0

This problem is explained in depth in this issue.

Using webpack I used this in webpack.config.js:

var plugins = [

    ...

    new webpack.ProvidePlugin({
        $: "jquery",
        jQuery: "jquery",
        'window.jQuery': 'jquery',
        'window.Tether': 'tether',
        tether: 'tether',
        Tether: 'tether'
    })
];

It seems like Tether was the one it was looking for:

var Tooltip = function ($) {

  /**
   * Check for Tether dependency
   * Tether - http://tether.io/
   */
  if (typeof Tether === 'undefined') {
    throw new Error('Bootstrap tooltips require Tether (http://tether.io/)');
  }

The simplest of all

Create a config.ts file

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

export class Config {
    url: string = 'http://localhost:3000';
    httpOptions: any = {
        headers: new HttpHeaders({
           'Content-Type': 'application/json',
           'Authorization': JSON.parse(localStorage.getItem('currentUser')).token
        })
    }
}

Then on your service, just import the config.ts file

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

@Injectable()
export class OrganizationService {
  config = new Config;

  constructor(
    private http: HttpClient
  ) { }

  addData(data): Observable<any> {
     let sendAddLink = `${this.config.url}/api/addData`;

     return this.http.post(sendAddLink , data, this.config.httpOptions).pipe(
       tap(snap => {
      return snap;
        })
    );
 } 

I think it was the simplest and the safest.

You should use

this.router.parent.navigate(['/About']);

As well as specifying the route path, you can also specify your route's name:

{ path:'/About', name: 'About',   ... }

this.router.parent.navigate(['About']);

Router 3.0.0-beta.2 should be

this.router.events.subscribe(path => {
  console.log('path = ', path);
});

I have solved this issue in the case of a self hosted parse-server using a one year signed certificate rather than the option "NSAllowsArbitraryLoads"

Parse Server as any node.js server presents a public https url that you have to specify. For instance:

parse-server --appId --masterKey --publicServerURL https://your.public.url/some_nodejs

Feel free to give a look to my configuration files

This answer copies the @abosancic answer but adds extra safety to avoid CORS exploit.

Tip 1: Do not reflect the incoming Origin as is without checking the list of allowed hosts to access.

Tip 2: Allow credentialed request only for whitelisted hosts.

            response.setHeader("Access-Control-Allow-Credentials", "true");
        }

        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Content-Type, Accept, X-Requested-With, remember-me");

        chain.doFilter(req, res);
    }

    @Override
    public void init(FilterConfig filterConfig) {
    }

    @Override
    public void destroy() {
    }

    public String getOriginToAllow(String incomingOrigin) {
        if(allowedOrigins.contains(incomingOrigin.toLowerCase())) {
            return incomingOrigin;
        } else {
            return null;
        }
    }
}

Basic debugging using Spring's DebugFilter can be configured like this:

@EnableWebSecurity
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.debug(true);
    }
}

Update in ASP.NET Core Version >= 2.0

In the Controller:

public class YourControllerNameController : Controller
{
    private readonly UserManager<ApplicationUser> _userManager;
    
    public YourControllerNameController(UserManager<ApplicationUser> userManager)
    {
        _userManager = userManager;
    }

    public async Task<IActionResult> YourMethodName()
    {
        var userId =  User.FindFirstValue(ClaimTypes.NameIdentifier) // will give the user's userId
        var userName =  User.FindFirstValue(ClaimTypes.Name) // will give the user's userName
        
        // For ASP.NET Core <= 3.1
        ApplicationUser applicationUser = await _userManager.GetUserAsync(User);
        string userEmail = applicationUser?.Email; // will give the user's Email

       // For ASP.NET Core >= 5.0
       var userEmail =  User.FindFirstValue(ClaimTypes.Email) // will give the user's Email
    }
}

In some other class:

public class OtherClass
{
    private readonly IHttpContextAccessor _httpContextAccessor;
    public OtherClass(IHttpContextAccessor httpContextAccessor)
    {
       _httpContextAccessor = httpContextAccessor;
    }

   public void YourMethodName()
   {
      var userId = _httpContextAccessor.HttpContext.User.FindFirstValue(ClaimTypes.NameIdentifier);
   }
}

Then you should register IHttpContextAccessor in the Startup class as follows:

public void ConfigureServices(IServiceCollection services)
{
    services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();

    // Or you can also register as follows

    services.AddHttpContextAccessor();
}

For more readability write extension methods as follows:

public static class ClaimsPrincipalExtensions
{
    public static T GetLoggedInUserId<T>(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        var loggedInUserId = principal.FindFirstValue(ClaimTypes.NameIdentifier);

        if (typeof(T) == typeof(string))
        {
            return (T)Convert.ChangeType(loggedInUserId, typeof(T));
        }
        else if (typeof(T) == typeof(int) || typeof(T) == typeof(long))
        {
            return loggedInUserId != null ? (T)Convert.ChangeType(loggedInUserId, typeof(T)) : (T)Convert.ChangeType(0, typeof(T));
        }
        else
        {
            throw new Exception("Invalid type provided");
        }
    }

    public static string GetLoggedInUserName(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        return principal.FindFirstValue(ClaimTypes.Name);
    }

    public static string GetLoggedInUserEmail(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        return principal.FindFirstValue(ClaimTypes.Email);
    }
}

Then use as follows:

public class YourControllerNameController : Controller
{
    public IActionResult YourMethodName()
    {
        var userId = User.GetLoggedInUserId<string>(); // Specify the type of your UserId;
        var userName = User.GetLoggedInUserName();
        var userEmail = User.GetLoggedInUserEmail();
    }
}

public class OtherClass
{
     private readonly IHttpContextAccessor _httpContextAccessor;
     public OtherClass(IHttpContextAccessor httpContextAccessor)
     {
         _httpContextAccessor = httpContextAccessor;
     }

     public void YourMethodName()
     {
         var userId = _httpContextAccessor.HttpContext.User.GetLoggedInUserId<string>(); // Specify the type of your UserId;
     }
}

Rebooting worked for me too. After upgrading to High Sierra I got tons of problems with password and it looks like I needed to enter the Password for the Keychain access to XCode.

// It happens when you are not setting the adapter during the creation phase: call notifyDataSetChanged() when api response is getting Its Working

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


        magazineAdapter = new MagazineAdapter(getContext(), null, this );
        newClipRecyclerView.setAdapter(magazineAdapter);
        magazineAdapter.notifyDataSetChanged();

       APICall();
}

public void APICall() {
    if(Response.isSuccessfull()){
    mRecyclerView.setAdapter(mAdapter);
   }
}
Just move setting the adapter into onCreate with an empty data and when you have the data call:

mAdapter.notifyDataSetChanged();

You can try/catch PDOExceptions (your configs could differ but the important part is the try/catch):

try {
        $dbh = new PDO(
            DB_TYPE . ':host=' . DB_HOST . ';dbname=' . DB_NAME . ';charset=' . DB_CHARSET,
            DB_USER,
            DB_PASS,
            [
                PDO::ATTR_PERSISTENT            => true,
                PDO::ATTR_ERRMODE               => PDO::ERRMODE_EXCEPTION,
                PDO::MYSQL_ATTR_INIT_COMMAND    => 'SET NAMES ' . DB_CHARSET . ' COLLATE ' . DB_COLLATE

            ]
        );
    } catch ( PDOException $e ) {
        echo 'ERROR!';
        print_r( $e );
    }

The print_r( $e ); line will show you everything you need, for example I had a recent case where the error message was like unknown database 'my_db'.

  public MessageAdapter(Context context, List<Messages> mMessageList) {

    this.mContext = context;
    this.mMessageList = mMessageList;

  }

I also had added on or extended additional columns into my AspNetUsers table. When I wanted to simply view this data I found many examples like the code above with "Extensions" etc... This really amazed me that you had to write all those lines of code just to get a couple values from the current users.

It turns out that you can query the AspNetUsers table like any other table:

 ApplicationDbContext db = new ApplicationDbContext();
 var user = db.Users.Where(x => x.UserName == User.Identity.Name).FirstOrDefault();

Run mysql_upgrade.

Check that

SHOW GRANTS FOR 'root'@'localhost';

says

GRANT ALL PRIVILEGES ON ... WITH GRANT OPTION 

Check that the table exists _mysql.proxies_priv_.

Access denied for user 'root'@'localhost' while attempting to grant privileges. How do I grant privileges?

You can do this thing using performSegueWithIdentifier function.

Syntax :

func performSegueWithIdentifier(identifier: String, sender: AnyObject?)

Example :

 performSegueWithIdentifier("homeScreenVC", sender: nil)

For the truly lazy (no typing, only totally easy copy and paste):

sudo usermod -aG vboxsf $USER

Log out and back in to make the change active.

I know it's a "me too" solution, but I am truly lazy and didn't find any other solution to appeal my innate apathy... :)

In material ui, state of checkbox can be fetched as

this.refs.complete.state.switched

Simple nltk.download() will not solve this issue. I tried the below and it worked for me:

in the nltk folder create a tokenizers folder and copy your punkt folder into tokenizers folder.

This will work.! the folder structure needs to be as shown in the picture

In my case, I had several instances of methods taking a closure with a signature like this (notice the optional array of dictionaries):

// 'results' being nil means "failure".
func queryItems(
    completion:( (results:[[String:AnyObject]]?)->(Void) )
    )
{
   // (async operation...)

...which I started to refactor into:

// 'results' is NEVER nil (at most, empty). Pass any errors to the 
//   failure: closure instead.
func queryItems(
    success:( (results:[[String:AnyObject]])->(Void) ),
    failure:( (error:NSError) -> (Void) )
    )
{
   // (async operation...)

...but did not finish, so some methods expected a closure with an optional argument and where being passed a non-optional one (or viceversa?), and I guess the compiler lost track.

I had the same error using an UpdateView

I had this:

if form.is_valid() and form2.is_valid():
    form.save()
    form2.save()
    return HttpResponseRedirect(self.get_success_url())

and I solved just doing:

if form.is_valid() and form2.is_valid():
    form.save()
    form2.save()
    return HttpResponseRedirect(reverse_lazy('adopcion:solicitud_listar'))

If you want to refresh the table without adding new data then use this:

First, create the API variable of your table like this:

var myTableApi = $('#mytable').DataTable(); // D must be Capital in this.

And then use refresh code wherever you want:

myTableApi.search(jQuery('input[type="search"]').val()).draw() ;

It will search data table with current search value (even if it's blank) and refresh data,, this work even if Datatable has server-side processing enabled.

If you have a container running as root that runs a script (which you can't change) that needs access to the sudo command, you can simply create a new sudo script in your $PATH that calls the passed command.

e.g. In your Dockerfile:

RUN if type sudo 2>/dev/null; then \ 
     echo "The sudo command already exists... Skipping."; \
    else \
     echo -e "#!/bin/sh\n\${@}" > /usr/sbin/sudo; \
     chmod +x /usr/sbin/sudo; \
    fi

You should never look to override certificate validation in code! If you need to do testing, use an internal/test CA and install the CA root certificate on the device or emulator. You can use BurpSuite or Charles Proxy if you don't know how to setup a CA.

Just execute this command in the spark directory:

cp conf/log4j.properties.template conf/log4j.properties

Edit log4j.properties:

# Set everything to be logged to the console
log4j.rootCategory=INFO, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.err
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{1}: %m%n

# Settings to quiet third party logs that are too verbose
log4j.logger.org.eclipse.jetty=WARN

log4j.logger.org.apache.spark.repl.SparkIMain$exprTyper=INFO
log4j.logger.org.apache.spark.repl.SparkILoop$SparkILoopInterpreter=INFO

Replace at the first line:

log4j.rootCategory=INFO, console

by:

log4j.rootCategory=WARN, console

Save and restart your shell. It works for me for Spark 1.1.0 and Spark 1.5.1 on OS X.

This new issue is caused by the latest version of Android.

Go to your project root folder, open gradle.properties, and add the following options:

org.gradle.daemon=true

org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

org.gradle.parallel=true

org.gradle.configureondemand=true

Then add these changes in your build.gradle file:

dexOptions {
        incremental = true
        preDexLibraries = false
        javaMaxHeapSize "4g" // 2g should be also OK
}

just change in settings.xml these as aliteralmind says:

  <server>
      <id>nexus-snapshots</id>
      <username>MY_SONATYPE_DOT_COM_USERNAME</username>
      <password>MY_SONATYPE_DOT_COM_PASSWORD</password>    
 </server>

you probably need to get the username / password from sonatype dot com.

You have to put:

<html ng-app="urlApp" ng-controller="urlCtrl">

This way the angular function can access into "window" object

You need to return your promise to the calling function.

islogged:function(){
    var cUid=sessionService.get('uid');
    alert("in loginServce, cuid is "+cUid);
    var $checkSessionServer=$http.post('data/check_session.php?cUid='+cUid);
    $checkSessionServer.then(function(){
        alert("session check returned!");
        console.log("checkSessionServer is "+$checkSessionServer);
    });
    return $checkSessionServer; // <-- return your promise to the calling function
}

I experienced the same problem with FZ-client, while my notebook connected via WLAN and DSL/Router. In the Site Manager connection settings I was applied Host:ftp.domain-name, Encryption:Only use plain FTP (insecure) and User:username@domain-name. Then the FTP-client succesfully connected to my website server. More FTP connection information could be found in the CPanel of the webserver. Hope this helps.

When using JavaScript to access an HTML element, there is a good chance that the element is not on the page and therefore not in the dom as far as JavaScript is concerned, when the code to access that element runs.

This problem can occur even though you can visually see the HTML element in the browser window or have the code set to be called in the onload method.

I ran into this problem after writing code to repopulate specific div elements on a page after retrieving the cookies.

What is apparently happening is that even though the HTML has loaded and is outputted by the browser, the JavaScript code is running before the page has completed loading.

The solution to this problem which just may be a JavaScript bug, is to place the code you want to run within a timer that delays the code run by 400 milliseconds or so. You will need to test it to determine how quick you can run the code.

I also made a point to test for the element before attempting to assign values to it.

window.setTimeout(function() { if( document.getElementById("book") ) { // Code goes here }, 400 /* but after 400 ms */);

This may or may not help you solve your problem, but keep this in mind and understand that browsers do not always function as expected.

It is Purely swift notation an working for me

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
    {
        var cellIdentifier:String = "CustomFields"
        var cell:CustomCell? = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as? CustomCell
        if (cell == nil)
        {
            var nib:Array = NSBundle.mainBundle().loadNibNamed("CustomCell", owner: self, options: nil)
            cell = nib[0] as? CustomCell
        }
        return cell!
    }

You need to use an older version of the data connectivity driver (2007 Office System Driver: Data Connectivity Components) and select Excel version 2007-2010 in the connection manager configuration window. I assume the newest data connectivity driver for Office 2016 is corrupt

In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.

In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.

The /me/friendlists endpoint and user_friendlists permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.

If you want to access a list of non-app-using friends, there are two options:

1. If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.

2. If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.

In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission).

For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.

Add the following to your conf file

fastcgi_buffers 16 16k; 
fastcgi_buffer_size 32k;

Another approach is in your chtml

<input type="hidden" id="hdnSession" data-value="@Request.RequestContext.HttpContext.Session['someKey']" />

  and the script is

var sessionValue= $("#hdnSession").data('value');

or you may access directly by

 jQuery(document).ready(function ($) {
        var value = '@Request.RequestContext.HttpContext.Session["someKey"]';
    }); 

To start redis with a config file all you need to do is specifiy the config file as an argument:

redis-server /root/config/redis.rb

Instead of using and killing PID's I would suggest creating an init script for your service

I would suggest taking a look at the Installing Redis more properly section of http://redis.io/topics/quickstart. It will walk you through setting up an init script with redis so you can just do something like service redis_server start and service redis_server stop to control your server.

I am not sure exactly what distro you are using, that article describes instructions for a Debian based distro. If you are are using a RHEL/Fedora distro let me know, I can provide you with instructions for the last couple of steps, the config file and most of the other steps will be the same.

Here is my Approach based on DarKalimHero's Suggestion by selecting only on Explorer.exe processes

Function Get-RdpSessions 
{
    param(
        [string]$computername 
    )

    $processinfo = Get-WmiObject -Query "select * from win32_process where name='explorer.exe'" -ComputerName $computername

    $processinfo | ForEach-Object { $_.GetOwner().User } | Sort-Object -Unique | ForEach-Object { New-Object psobject -Property @{Computer=$computername;LoggedOn=$_} } | Select-Object Computer,LoggedOn
}

I've solved using only @JsonIgnore like @kryger has suggested. So your getter will become:

@JsonIgnore
public String getEncryptedPwd() {
    return this.encryptedPwd;
}

You can set @JsonIgnore of course on field, setter or getter like described here.

And, if you want to protect encrypted password only on serialization side (e.g. when you need to login your users), add this @JsonProperty annotation to your field:

@JsonProperty(access = Access.WRITE_ONLY)
private String encryptedPwd;

More info here.

Your Custom AuthenticationProvider class should be annotated with the following:

@Transactional

This will make sure the presence of the hibernate session there as well.

I had the same issue. I am currently using Asp.net Core 2.2. I solved this problem with the following piece of code.

using Microsoft.AspNetCore.Identity;
var user = await _userManager.FindByEmailAsync(User.Identity.Name);

I hope this will be useful to someone.

For macOS 10.14 Mojave, make sure you have already installed command line tools via xcode-select --install and the run the following command to install std headers.

sudo open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

Now try your command again.

Try following steps

1. Run this command on Terminal or CMD - npm cache clean

2. Go to this folder on windows %APPDATA%\npm-cache And delete folder which you want to install module (Ex:- laravel-elixir) or if you are using PowerShell, $env:APPDATA\npm-cache

3. Then Run your command EX:- npm install laravel-elixir

You can do an http DELETE via a URL like /users/1/roles/2. That would be the most RESTful way to do it.

Otherwise I guess you can just pass the user id as part of the query params? Something like

$http.delete('/roles/' + roleid, {params: {userId: userID}}).then...

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

First, Identify the user you are logged in as:

 select user();
 select current_user();

The result for the first command is what you attempted to login as, the second is what you actually connected as. Confirm that you are logged in as root@localhost in mysql.

Grant_priv to root@localhost. Here is how you can check.

mysql> SELECT host,user,password,Grant_priv,Super_priv FROM mysql.user;
+-----------+------------------+-------------------------------------------+------------+------------+
| host      | user             | password                                  | Grant_priv | Super_priv |
+-----------+------------------+-------------------------------------------+------------+------------+
| localhost | root             | ***************************************** | N          | Y          |
| localhost | debian-sys-maint | ***************************************** | Y          | Y          |
| localhost | staging          | ***************************************** | N          | N          |
+-----------+------------------+-------------------------------------------+------------+------------+

You can see that the Grant_priv is set to N for root@localhost. This needs to be Y. Below is how to fixed this:

UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='root';
FLUSH PRIVILEGES;
GRANT ALL ON *.* TO 'root'@'localhost';

I logged back in, it was fine.

No you don't have to put credentials, You have to put headers on client side eg:

 $http({
        url: 'url of service',
        method: "POST",
        data: {test :  name },
        withCredentials: true,
        headers: {
                    'Content-Type': 'application/json; charset=utf-8'
        }
    });

And and on server side you have to put headers to this is example for nodejs:

/**
 * On all requests add headers
 */
app.all('*', function(req, res,next) {


    /**
     * Response settings
     * @type {Object}
     */
    var responseSettings = {
        "AccessControlAllowOrigin": req.headers.origin,
        "AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5,  Date, X-Api-Version, X-File-Name",
        "AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
        "AccessControlAllowCredentials": true
    };

    /**
     * Headers
     */
    res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
    res.header("Access-Control-Allow-Origin",  responseSettings.AccessControlAllowOrigin);
    res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
    res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);

    if ('OPTIONS' == req.method) {
        res.send(200);
    }
    else {
        next();
    }


});

Its not about security settings .. its the UserAgent in IE11 ( in IE11 its Trident while all previous versions of MS IE were MSIE ) so I suppose that Java deployment tool cannot recognize new baby of MS .. and send you back to install Java ..

I already ask if there is any temporarily solution till Oracle guys make new release

JavaFx web not working with Internet Explorer 11 with JRE7

update:

btw applet is working at least on the oracle test java page : http://www.java.com/en/download/installed.jsp I just uninstall all JAVA from PC then reinstall latest version and disable then enable "Java(tm) Plug-In 2 SSV Helper and Java(tm) Plug-In SSV Helper " @ manage add-ons. before testing java on web. and it works ..

so I think its JavaFX not applet .. since JavafX is using dtjava.js while webstart(applet) using deployJava.js.

dependencies {
    compile 'com.android.support:support-v4:19.1.+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

This gets conflicted if you have the support jar in your libs folder. If you have the support jar in your project libs folder and you have the module dependency added to compile 'com.android.support:support-v4:13.0.+' the UNEXPECTED_TOPLEVEL_DEPENDANCY exception will be thrown.

In my case, I'm on Windows and following the answer by Cameron above only works if you use the full name of the ndk-build which is ndk-build.cmd. I have to clean and rebuild the project, then restart the emulator before getting the app to work (Actually I imported the sample HelloJni from NDK, into Android Studio). However, make sure the path to NDK does not contain space.

Finally, my build.gradle is full listed as below:

I recommend this solution :

1. Don't use response.End();

2. Declare this global var : bool isFileDownLoad;

3. Just after your (response.Write(sw.ToString());) set ==> isFileDownLoad = true;

4. Override your Render like :

   /// AEG : Very important to handle the thread aborted exception
   
   override protected void Render(HtmlTextWriter w)
   {
        if (!isFileDownLoad) base.Render(w);
   }

Right now the asp.mvc project template creates an account controller that gets the usermanager this way:

HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>()

The following works for me:

ApplicationUser user = HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>().FindById(User.Identity.GetUserId());

In my case it was caused by (/etc/ssh/sshd_config):

PermitRootLogin no

Changed to yes, restarted the service and got in normally.

Check if any SDK platform was partially installed. If it does, reinstall it.

Steps:

• Just download create_table.sql from GitHub and save that file in your system.
• Then go to your phpMyAdmin.
• And click on Import from upper tab.
• At last select create_table.sql and upload that.

After all it works for me and hopefully work for you.

Modern era update, as stated by mimoralea:

In case that you are using ruby 2.0 or 2.2 (thanks @patrick-davey).

sudo apt-get install ruby2.0-dev
sudo apt-get install ruby2.2-dev
sudo apt-get install ruby2.3-dev

or, generic way:

sudo apt-get install ruby-dev

or

sudo apt-get install ruby`ruby -e 'puts RUBY_VERSION[/\d+\.\d+/]'`-dev

The first link you’ve posted is exactly your case: there is no ruby development environment installed. Development env is needed to compile ruby extensions, which are mostly written in C. Proxy has nothing to do with the problem: everything is downloaded fine, just compilation fails.

I would suggest you to install ruby-dev (ruby-devel for rpm-based distros) package onto you target machine.

gcc package might be needed as well.

Try:

$ sudo apt-get install ruby-dev

Or, for Redhat distro:

$ sudo yum install ruby-devel

Or, for [open]SuSE:

$ sudo zypper install ruby-devel

I was having the same issue implementing in Angular 9. These are the two steps I did:

1. Change your YouTube URL from https://youtube.com/your_code to https://youtube.com/embed/your_code.

2. And then pass the URL through DomSanitizer of Angular.

   import { Component, OnInit } from "@angular/core";
   import { DomSanitizer } from '@angular/platform-browser';
   
   @Component({
     selector: "app-help",
     templateUrl: "./help.component.html",
     styleUrls: ["./help.component.scss"],
   })
   export class HelpComponent implements OnInit {
   
     youtubeVideoLink: any = 'https://youtube.com/embed/your_code'
   
     constructor(public sanitizer: DomSanitizer) {
       this.sanitizer = sanitizer;   
     }
   
     ngOnInit(): void {}
   
     getLink(){
       return this.sanitizer.bypassSecurityTrustResourceUrl(this.youtubeVideoLink);
     }
   
   }
   

   <iframe width="420" height="315" [src]="getLink()" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

It probably means that mongodb is not running. You will have to enable it through the command line or on windows run services.msc and enable mongodb.

Use File.AppendAllText instead:

File.AppendAllText(filePath + "log.txt", log);

I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics

If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.

UIBarPositionTopAttached

Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.

Workaround: This is a problem we have observed too, in Windows Server 2012 R2. I haven't found a reason or solution yet. Here is my work around.

During installation while error is shown, go to Services.msc. Find the service which throws the error, then re-enter the password in the service's log-in information. Then, hit "retry" in setup. It works.

The error will not be shown for same user again. But will be shown for a different user.

After creating the LoginViewController and TabBarController, we need to add a StoryboardID as “loginViewController” and “tabBarController” respectively.

Then I prefer to create the Constant struct:

struct Constants {
    struct StoryboardID {
        static let signInViewController = "SignInViewController"
        static let mainTabBarController = "MainTabBarController"
    }

    struct kUserDefaults {
        static let isSignIn = "isSignIn"
    }
}

In LoginViewController add IBAction:

@IBAction func tapSignInButton(_ sender: UIButton) {
    UserDefaults.standard.set(true, forKey: Constants.kUserDefaults.isSignIn)
    Switcher.updateRootViewController()
}

In ProfileViewController add IBAction:

@IBAction func tapSignOutButton(_ sender: UIButton) {
    UserDefaults.standard.set(false, forKey: Constants.kUserDefaults.isSignIn)
    Switcher.updateRootViewController()
}

In AppDelegate add line of code in didFinishLaunchingWithOptions:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    Switcher.updateRootViewController()

    return true
}

Finally create Switcher class:

import UIKit

class Switcher {

    static func updateRootViewController() {

        let status = UserDefaults.standard.bool(forKey: Constants.kUserDefaults.isSignIn)
        var rootViewController : UIViewController?

        #if DEBUG
        print(status)
        #endif

        if (status == true) {
            let mainStoryBoard = UIStoryboard(name: "Main", bundle: nil)
            let mainTabBarController = mainStoryBoard.instantiateViewController(withIdentifier: Constants.StoryboardID.mainTabBarController) as! MainTabBarController
            rootViewController = mainTabBarController
        } else {
            let mainStoryBoard = UIStoryboard(name: "Main", bundle: nil)
            let signInViewController = mainStoryBoard.instantiateViewController(withIdentifier: Constants.StoryboardID.signInViewController) as! SignInViewController
            rootViewController = signInViewController
        }

        let appDelegate = UIApplication.shared.delegate as! AppDelegate
        appDelegate.window?.rootViewController = rootViewController

    }

}

That is all!

I think that. When guest is launching page, but Admin is not logged in we don`t show something, for example the Chat.

add_action('init', 'chat_status');

function chat_status(){

    if( get_option('admin_logged') === 1) { echo "<style>.chat{display:block;}</style>";}
        else { echo "<style>.chat{display:none;}</style>";}

}



add_action('wp_login', function(){

    if( wp_get_current_user()->roles[0] == 'administrator' ) update_option('admin_logged', 1);
});


add_action('wp_logout', function(){
    if( wp_get_current_user()->roles[0] == 'administrator' ) update_option('admin_logged', 0);
});

create a logfile in php, to do it you need to pass data on function and it will create log file for you.

function wh_log($log_msg)
{
    $log_filename = "log";
    if (!file_exists($log_filename)) 
    {
        // create directory/folder uploads.
        mkdir($log_filename, 0777, true);
    }
    $log_file_data = $log_filename.'/log_' . date('d-M-Y') . '.log';
    // if you don't add `FILE_APPEND`, the file will be erased each time you add a log
    file_put_contents($log_file_data, $log_msg . "\n", FILE_APPEND);
} 
// call to function
wh_log("this is my log message");

I was also facing the same problem i did the following steps to resolve the issue

1. I edited the file /etc/php.ini and searched the path session.save_path = "/var/lib/php/session" you have to give your session info

2 After that just changed the permission given below *chown root.apache /var/lib/php/session * That's it. These above steps resolve my issue

Maybe the current user is not root,try sudo mysql -uroot -p ,I successed just now.

If you are using Ubuntu try to install following lib file

sudo apt-get install libpq-dev

and then

gem install pg

worked for me.

Under normal circumstances,out of bound of array when you encounter the error. So,check uo your array subscript.

As the error says, you need to make sure that your sql server is running and listening on port 1433. If server is running then you need to check whether there is some firewall rule rejecting the connection on port 1433.

Here are the commands that can be useful to troubleshoot:

1. Use netstat -a to check whether sql server is listening on the desired port
2. As gerrytan mentioned in answer, you can try to do the telnet on the host and port

In our case it turned out that the error happened because we have a custom filter in our application which does HttpServletResponse sendRedirect() to other url.

For some reason, the redirection is not closing the keep-alive status of the connection, hence the timeout exception.

We checked with Tomcat Docs and when we disabled the maxKeepAliveRequests by setting it's value to 1 and the error stopped showing up.

For now we do not have the actual solution to the error.

Just replace localhost with 127.0.0.1.

(The answer is based on answers of other people on this page.)

You should really use Angular UI for that needs. Check it out: Angular UI Dialog

In a nutshell, with Angular UI dialog, you can pass variable from a controller to the dialog controller using resolve. Here's your "from" controller:

var d = $dialog.dialog({
  backdrop: true,
  keyboard: true,
  backdropClick: true,
  templateUrl:  '<url_of_your_template>',
  controller: 'MyDialogCtrl',
  // Interesting stuff here.
  resolve: {
    username: 'foo'
  }
});

d.open();

And in your dialog controller:

angular.module('mymodule')
  .controller('MyDialogCtrl', function ($scope, username) {
  // Here, username is 'foo'
  $scope.username = username;
}

EDIT: Since the new version of the ui-dialog, the resolve entry becomes:

resolve: { username: function () { return 'foo'; } }

Getting the Id is pretty straight forward and you've solved that.

Your second question though is a little more involved.

So, this is all prerelease stuff right now, but the common problem you're facing is where you're extending the user with new properties ( or an Items collection in you're question).

Out of the box you'll get a file called IdentityModel under the Models folder (at the time of writing). In there you have a couple of classes; ApplicationUser and ApplicationDbContext. To add your collection of Items you'll want to modify the ApplicationUser class, just like you would if this were a normal class you were using with Entity Framework. In fact, if you take a quick look under the hood you'll find that all the identity related classes (User, Role etc...) are just POCOs now with the appropriate data annotations so they play nice with EF6.

Next, you'll need to make some changes to the AccountController constructor so that it knows to use your DbContext.

public AccountController()
{
    IdentityManager = new AuthenticationIdentityManager(
    new IdentityStore(new ApplicationDbContext()));
}

Now getting the whole user object for your logged in user is a little esoteric to be honest.

    var userWithItems = (ApplicationUser)await IdentityManager.Store.Users
    .FindAsync(User.Identity.GetUserId(), CancellationToken.None);

That line will get the job done and you'll be able to access userWithItems.Items like you want.

HTH

You can also use indexValue attribute for passing multiple parameters via object:

var someData = "hello";

jQuery.ajax({
    url: "http://maps.google.com/maps/api/js?v=3",
    indexValue: {param1:someData, param2:"Other data 2", param3: "Other data 3"},
    dataType: "script"
}).done(function() {
    console.log(this.indexValue.param1);
    console.log(this.indexValue.param2);
    console.log(this.indexValue.param3);
});

That's a problem with your version of jquery. Look here https://code.jquery.com/ and add this script

It didn't like my user privilege so I SUDO it. (in bash << sudo set user and password) (this gives username of root and sets the password to nothing) (On Mac)

To create the regex from a string, you have to use JavaScript's RegExp object.

If you also want to match/replace more than one time, then you must add the g (global match) flag. Here's an example:

var stringToGoIntoTheRegex = "abc";
var regex = new RegExp("#" + stringToGoIntoTheRegex + "#", "g");
// at this point, the line above is the same as: var regex = /#abc#/g;

var input = "Hello this is #abc# some #abc# stuff.";
var output = input.replace(regex, "!!");
alert(output); // Hello this is !! some !! stuff.

JSFiddle demo here.

In the general case, escape the string before using as regex:

Not every string is a valid regex, though: there are some speciall characters, like ( or [. To work around this issue, simply escape the string before turning it into a regex. A utility function for that goes in the sample below:

function escapeRegExp(stringToGoIntoTheRegex) {
    return stringToGoIntoTheRegex.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');
}

var stringToGoIntoTheRegex = escapeRegExp("abc"); // this is the only change from above
var regex = new RegExp("#" + stringToGoIntoTheRegex + "#", "g");
// at this point, the line above is the same as: var regex = /#abc#/g;

var input = "Hello this is #abc# some #abc# stuff.";
var output = input.replace(regex, "!!");
alert(output); // Hello this is !! some !! stuff.

JSFiddle demo here.

Note: the regex in the question uses the s modifier, which didn't exist at the time of the question, but does exist -- a s (dotall) flag/modifier in JavaScript -- today.

I have had a similar problem before where it turned out to be the web brower (chrome in my case) that was the issue.

If you are using chrome, try launching it so:

For Windows:

1) Create a shortcut to Chrome on your desktop. Right-click on the shortcut and choose Properties, then switch to “Shortcut” tab.

2) In the “Target” field, append the following: –args –disable-web-security

For Mac, Open a terminal window and run this from command-line: open ~/Applications/Google\ Chrome.app/ –args –disable-web-security

You may access the authenticated user via the Auth facade:

use Illuminate\Support\Facades\Auth;

// Get the currently authenticated user...
$user = Auth::user();

// Get the currently authenticated user's ID...
$id = Auth::id();

I just thought I'd share that I found the answer to my own question.

Writing out my problem made it even more clear to me, and I further investigated into where I thought my problem lay: the ssh key

Turns out I was right. The issue wasn't with the key itself, but rather that I had not added it to my local Mac's list of known ssh keys. So even though my Heroku account had the correct key uploaded, my Mac could not authenticate with it because it could not find that key on my computer. The solution?

ssh-add ~/.ssh/id_rsa
#and, to confirm it's been added to the known list of keys
ssh-add -l

I would like to give credit to https://help.github.com/articles/error-permission-denied-publickey for being a good reference.

You can set data to session simply like this in Codeigniter:

$this->load->library('session');
$this->session->set_userdata(array(
    'user_id'  => $user->uid,
    'username' => $user->username,
    'groupid'  => $user->groupid,
    'date'     => $user->date_cr,
    'serial'   => $user->serial,
    'rec_id'   => $user->rec_id,
    'status'   => TRUE
));

and you can get it like this:

$u_rec_id = $this->session->userdata('rec_id');
$serial = $this->session->userdata('serial');

The Instagram API requires user authentication through OAuth to access the recent media endpoint for a user. There doesn't appear to be any other way right now to get all media for a user.

You mentioned Ubuntu so I'm going to guess you installed the PostgreSQL packages from Ubuntu through apt.

If so, the postgres PostgreSQL user account already exists and is configured to be accessible via peer authentication for unix sockets in pg_hba.conf. You get to it by running commands as the postgres unix user, eg:

sudo -u postgres createuser owning_user
sudo -u postgres createdb -O owning_user dbname

This is all in the Ubuntu PostgreSQL documentation that's the first Google hit for "Ubuntu PostgreSQL" and is covered in numerous Stack Overflow questions.

(You've made this question a lot harder to answer by omitting details like the OS and version you're on, how you installed PostgreSQL, etc.)

You can use the request object to find the logged in user

def my_view(request):
    username = None
    if request.user.is_authenticated():
        username = request.user.username

According to https://docs.djangoproject.com/en/2.0/releases/1.10/

In version Django 2.0 the syntax has changed to

request.user.is_authenticated

You cannot exactly get a list of commands started with nohup but you can see them along with your other processes by using the command ps x. Commands started with nohup will have a question mark in the TTY column.

The RestTemplate getForObject() method does not support setting headers. The solution is to use the exchange() method.

So instead of restTemplate.getForObject(url, String.class, param) (which has no headers), use

HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...

HttpEntity entity = new HttpEntity(headers);

ResponseEntity<String> response = restTemplate.exchange(
    url, HttpMethod.GET, entity, String.class, param);

Finally, use response.getBody() to get your result.

This question is similar to this question.

node does something like this:

module.exports = exports = {}

module.exports and exports refer to same object.

This is done just for convenience. so instead of writing something like this

module.exports.PI = 3.14

we can write

exports.PI = 3.14

so it is ok to add a property to exports but assigning it to a different object is not ok

exports.add = function(){
.
.
} 

? this is OK and same as module.exports.add = function(){...}

exports = function(){
.
.
} 

? this is not ok and and empty object will be returned as module.exports still refers to {} and exports refer to different object.

I needed to import javaee-api as well.

  <dependency>
     <groupId>javax</groupId>
     <artifactId>javaee-api</artifactId>
     <version>7.0</version>
  </dependency>

Easy way

public interface IRequireViewIdentification
{
    Guid ViewID { get; }
}

Implement to ViewModel

public class MyViewVM : IRequireViewIdentification
{
    private Guid _viewId;

    public Guid ViewID
    {
        get { return _viewId; }
    }

    public MyViewVM()
    {
        _viewId = Guid.NewGuid();
    }
}

Add general window manager helper

public static class WindowManager
{
    public static void CloseWindow(Guid id)
    {
        foreach (Window window in Application.Current.Windows)
        {
            var w_id = window.DataContext as IRequireViewIdentification;
            if (w_id != null && w_id.ViewID.Equals(id))
            {
                window.Close();
            }
        }
    }
}

And close it like this in viewmodel

WindowManager.CloseWindow(ViewID);

The answer by 0x90h helped a lot...

I saved this file as u.ftp:

open 10.155.8.215 
user
password
lcd /D "G:\Subfolder\"
cd  folder/
binary
mget file.csv
disconnect
quit

I then ran this command:

ftp -i -s:u.ftp

And it worked!!!

Thanks a lot man :)

I like the approach and implemented it on server-side without doing any authentication related thing on front-end

My 'technique' on my latest app is.. the client doesn't care about Auth. Every single thing in the app requires a login first, so the server just always serves a login page unless an existing user is detected in the session. If session.user is found, the server just sends index.html. Bam :-o

Look for the comment by "Andrew Joslin".

https://groups.google.com/forum/?fromgroups=#!searchin/angular/authentication/angular/POXLTi_JUgg/VwStpoWCPUQJ

You have the annotation in the wrong place - it needs to be on the class, not the field. i.e:

@JsonInclude(Include.NON_NULL) //or Include.NON_EMPTY, if that fits your use case 
public static class Request {
  // ...
}

As noted in comments, in versions below 2.x the syntax for this annotation is:

@JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL) // or JsonSerialize.Inclusion.NON_EMPTY

The other option is to configure the ObjectMapper directly, simply by calling mapper.setSerializationInclusion(Include.NON_NULL);

(for the record, I think the popularity of this answer is an indication that this annotation should be applicable on a field-by-field basis, @fasterxml)

//BEWARE
//This works ONLY if the server returns 401 first
//The client DOES NOT send credentials on first request
//ONLY after a 401
client.Credentials = new NetworkCredential(userName, passWord); //doesnt work

//So use THIS instead to send credentials RIGHT AWAY
string credentials = Convert.ToBase64String(
    Encoding.ASCII.GetBytes(userName + ":" + password));
client.Headers[HttpRequestHeader.Authorization] = string.Format(
    "Basic {0}", credentials);

The MDN documentation shows how the getItem method is implementated:

Object.defineProperty(oStorage, "getItem", {
      value: function (sKey) { return sKey ? this[sKey] : null; },
      writable: false,
      configurable: false,
      enumerable: false
    });

If the value isn't set, it returns null. You are testing to see if it is undefined. Check to see if it is null instead.

if(localStorage.getItem("username") === null){

I had the same issue and took a whole day to figure out the problem. This error message by Facebook SDK is very vague. I had this problem due to openURL: method being overwritten in MyApplication. I removed the overwritten method and facebook login worked fine.

Any user with a valid shell in /etc/passwd can potentially login. If you want to improve security, set up SSH with public-key authentication (there is lots of info on the web on doing this), install a public key in one user's ~/.ssh/authorized_keys file, and disable password-based authentication. This will prevent anybody except that one user from logging in, and will require that the user have in their possession the matching private key. Make sure the private key has a decent passphrase.

To prevent bots from trying to get in, run SSH on a port other than 22 (i.e. 3456). This doesn't improve security but prevents script-kiddies and bots from cluttering up your logs with failed attempts.

Why does it work in Chrome and not Firefox?

The W3 spec for CORS preflight requests clearly states that user credentials should be excluded. There is a bug in Chrome and WebKit where OPTIONS requests returning a status of 401 still send the subsequent request.

Firefox has a related bug filed that ends with a link to the W3 public webapps mailing list asking for the CORS spec to be changed to allow authentication headers to be sent on the OPTIONS request at the benefit of IIS users. Basically, they are waiting for those servers to be obsoleted.

How can I get the OPTIONS request to send and respond consistently?

Simply have the server (API in this example) respond to OPTIONS requests without requiring authentication.

Kinvey did a good job expanding on this while also linking to an issue of the Twitter API outlining the catch-22 problem of this exact scenario interestingly a couple weeks before any of the browser issues were filed.

Missing ; after var_dump($row)

For me, the problem was a ContextRefreshedEvent handler. I was doing some data initilization but at that point in the application the Authentication had not been set. It was a catch 22 since the system needed an authentication to authorize and it needed authorization to get the authentication details :). I ended up loosening the authorization from a class level to a method level.

Go to magento/var/report and open the file with the Error log record number name i.e 673618173351 in your case. In that file you can find the complete description of the error.

For log files like system.log and exception.log, go to magento/var/log/.

for example kill pts/0

pkill -9 -t pts/0

You need to set the location header as follows:

header('Location: http://www.example.com/');

Replacing http://www.example.com of course with the url of your landing page.

Add this where you have finished logging the user in.

Note: When redirecting the user will be immediately redirected so you're message probably won't display.

Additionally, you need to move your PHP code to the top of the file for this solution to work.

On another side note, please see my comment above regarding the use of the deprecated mysql statements and consider using the newer, safer and improved mysqli or PDO statements.

A nice Java 7+ answer from Benoit Blanchon can be found here:

With Java 7, you can use Files.createDirectories().

For instance:

Files.createDirectories(Paths.get("/path/to/directory"));

You can also use Apache's ExceptionUtils.

Example:

import org.apache.commons.lang.exception.ExceptionUtils;
import org.apache.log4j.Logger;


public class Test {

    static Logger logger = Logger.getLogger(Test.class);

    public static void main(String[] args) {

        try{
            String[] avengers = null;
            System.out.println("Size: "+avengers.length);
        } catch (NullPointerException e){
            logger.info(ExceptionUtils.getFullStackTrace(e));
        }
    }

}

Console output:

java.lang.NullPointerException
    at com.aimlessfist.avengers.ironman.Test.main(Test.java:11)

You can use a Custom SuccessHandler extending SimpleUrlAuthenticationSuccessHandler for redirecting users to different URLs when login according to their assigned roles.

CustomSuccessHandler class provides custom redirect functionality:

package com.mycompany.uomrmsweb.configuration;

import java.io.IOException;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.core.Authentication;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.web.DefaultRedirectStrategy;
import org.springframework.security.web.RedirectStrategy;
import org.springframework.security.web.authentication.SimpleUrlAuthenticationSuccessHandler;
import org.springframework.stereotype.Component;

@Component
public class CustomSuccessHandler extends SimpleUrlAuthenticationSuccessHandler{

    private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();

    @Override
    protected void handle(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException {
        String targetUrl = determineTargetUrl(authentication);

        if (response.isCommitted()) {
            System.out.println("Can't redirect");
            return;
        }

        redirectStrategy.sendRedirect(request, response, targetUrl);
    }

    protected String determineTargetUrl(Authentication authentication) {
        String url="";

        Collection<? extends GrantedAuthority> authorities =  authentication.getAuthorities();

        List<String> roles = new ArrayList<String>();

        for (GrantedAuthority a : authorities) {
            roles.add(a.getAuthority());
        }

        if (isStaff(roles)) {
            url = "/staff";
        } else if (isAdmin(roles)) {
            url = "/admin";
        } else if (isStudent(roles)) {
            url = "/student";
        }else if (isUser(roles)) {
            url = "/home";
        } else {
            url="/Access_Denied";
        }

        return url;
    }

    public void setRedirectStrategy(RedirectStrategy redirectStrategy) {
        this.redirectStrategy = redirectStrategy;
    }
    protected RedirectStrategy getRedirectStrategy() {
        return redirectStrategy;
    }

    private boolean isUser(List<String> roles) {
        if (roles.contains("ROLE_USER")) {
            return true;
        }
        return false;
    }

    private boolean isStudent(List<String> roles) {
        if (roles.contains("ROLE_Student")) {
            return true;
        }
        return false;
    }

    private boolean isAdmin(List<String> roles) {
        if (roles.contains("ROLE_SystemAdmin") || roles.contains("ROLE_ExaminationsStaff")) {
            return true;
        }
        return false;
    }

    private boolean isStaff(List<String> roles) {
        if (roles.contains("ROLE_AcademicStaff") || roles.contains("ROLE_UniversityAdmin")) {
            return true;
        }
        return false;
    }
}

Extending Spring SimpleUrlAuthenticationSuccessHandler class and overriding handle() method which simply invokes a redirect using configured RedirectStrategy [default in this case] with the URL returned by the user defined determineTargetUrl() method. This method extracts the Roles of currently logged in user from Authentication object and then construct appropriate URL based on there roles. Finally RedirectStrategy , which is responsible for all redirections within Spring Security framework , redirects the request to specified URL.

Registering CustomSuccessHandler using SecurityConfiguration class:

package com.mycompany.uomrmsweb.configuration;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("customUserDetailsService")
    UserDetailsService userDetailsService;

    @Autowired
    CustomSuccessHandler customSuccessHandler;

    @Autowired
    public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
            auth.userDetailsService(userDetailsService);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
        .antMatchers("/", "/home").access("hasRole('USER')")
        .antMatchers("/admin/**").access("hasRole('SystemAdmin') or hasRole('ExaminationsStaff')")
        .antMatchers("/staff/**").access("hasRole('AcademicStaff') or hasRole('UniversityAdmin')")
        .antMatchers("/student/**").access("hasRole('Student')")  
                    .and().formLogin().loginPage("/login").successHandler(customSuccessHandler)
        .usernameParameter("username").passwordParameter("password")
        .and().csrf()
        .and().exceptionHandling().accessDeniedPage("/Access_Denied");
    }
}

successHandler is the class responsible for eventual redirection based on any custom logic, which in this case will be to redirect the user [to student/admin/staff ] based on his role [USER/Student/SystemAdmin/UniversityAdmin/ExaminationsStaff/AcademicStaff].

When user gets to the login page use this to see where is come from

$_SERVER['HTTP_REFERER']

Then set this value into the session, and when he is authenticated use url from the session to redirect him back. But you should do some checking before, if the url is your site. Maybe he come from another site directly to login :)

Update for latest SDK:

Now @zeuter's answer is correct for Facebook SDK v4.7+:

LoginManager.getInstance().logOut();

Original answer:

Please do not use SessionTracker. It is an internal (package private) class, and is not meant to be consumed as part of the public API. As such, its API may change at any time without any backwards compatibility guarantees. You should be able to get rid of all instances of SessionTracker in your code, and just use the active session instead.

To answer your question, if you don't want to keep any session data, simply call closeAndClearTokenInformation when your app closes.

There are several Identity providers with SSO support out of the box, also third-party** products.

** The only problem with third party products is that they charge per user/month, and it can be quite expensive.

Some of the tools available and with APIs for .NET are:

• IdentityExpress (with Admin UI) by IdentityServer
• Centrify Identity Service
• Okta Identity (SAML 2.0)
• OneLogin

If you decide to go with your own implementation, you could use the frameworks below categorized by programming language.

• C#

  • IdentityServer3 (OAuth/OpenID protocols, OWIN/Katana)
  • IdentityServer4 (OAuth/OpenID protocols, ASP.NET Core)
  • OAuth 2.0 by Okta

• Javascript

  • passport-openidconnect (node.js)
  • oidc-provider (node.js)
  • openid-client (node.js)

• Python

  • pyoidc
  • Django OIDC Provider

I would go with IdentityServer4 and ASP.NET Core application, it's easy configurable and you can also add your own authentication provider. It uses OAuth/OpenID protocols which are newer than SAML 2.0 and WS-Federation.

The user that is configured to run this scheduled task must have "Log on as a batch job" rights on the computer that hosts the exe you are launching. This can be configured on the local security policy of the computer that hosts the exe. You can change the policy (on the server hosting the exe) under

Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment -> Log On As Batch Job

Add your user to this list (you could also make the user account a local admin on the machine hosting the exe).

Finally, you could also simply copy your exe from the network location to your local computer and run it from there instead.

Note also that a domain policy could be restricting "Log on as a batch job" rights at your organization.

You can also use DateTime class:

$time1 = new DateTime('09:00:59');
$time2 = new DateTime('09:01:00');
$interval = $time1->diff($time2);
echo $interval->format('%s second(s)');

Result:

1 second(s)

For RubyOnRails app add localhost If you use custom Postgresql version

This error is something else!

Here is how i Fixed it. I'm using xcode Version 6.1.1 and using swift. I got this error every time my app tried to perform a segue to jump to the next screen. Here what I did.

1. Checked that the button was connected to the right action.(This wasn't the problem, but still good to check)
2. Check that the button does not have any additional actions or outlets that you may have created by mistake. (This wasn't the problem, but still good to check)
3. Check the logs and make sure that all the buttons in the NEXT SCREEN have the correct actions, and if there are any segues, make sure that they have a unique identifier. (This was the problem)
   • One of the segues did not have a unique identifier
   • One of the buttons had an action and two outlets that I created by mistake.

Delete any additional outlets and make sure that you the segues to the next screen have unique identifiers.

Cheers,

Just finished a 2 hour wild goose chase trying to solve this. None of the posted answers worked for me. Im on a Mac (Mojave Version 10.14.6, Xcode Version 11.3).

It turns out the ruby file headers were missing so i had to run open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

That didnt work for me at first because the version of CommandLineTools i had installed did not have the "Packages" folder. So i uninstalled and reinstalled like this:

rm -rf /Library/Developer/CommandLineTools

xcode-select --install

Then i ran the previous command again:

open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

After install the error was fixed!

Use where_in()

$ids = array('20', '15', '22', '46', '86');
$this->db->where_in('id', $ids );

I had this same issue.

The solution for me was found in the Microsoft KB Article 2452723:

Windows Vista onwards scheduled tasks fail to run if the path in "Start in (Optional)" field has quotes

Basically, edit your scheduled task and take the Quotes out of the Start In field:

1. Open your Scheduled Task
2. Switch to "Actions" tab
3. Open your Action
4. Remove Quotes (") from the field "Start in (optional)"
5. Save and close all open dialogs

To get the relevant error message:

1) Convert 2147942667 to hex: 8007010B
2) Take last 4 digits (010B) and convert to decimal: 267
3) Run: net helpmsg 267
4) Result: "The directory name is invalid."

When doing;

a_file = open('E:\Python Win7-64-AMD 3.3\Test', encoding='utf-8')

...you're trying to open a directory as a file, which may (and on most non UNIX file systems will) fail.

Your other example though;

a_file = open('E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')

should work well if you just have the permission on a.txt. You may want to use a raw (r-prefixed) string though, to make sure your path does not contain any escape characters like \n that will be translated to special characters.

a_file = open(r'E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')

In order to populate referenced subdocuments, you need to explicitly define the document collection to which the ID references to (like created_by: { type: Schema.Types.ObjectId, ref: 'User' }).

Given this reference is defined and your schema is otherwise well defined as well, you can now just call populate as usual (e.g. populate('comments.created_by'))

Proof of concept code:

// Schema
var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var UserSchema = new Schema({
  name: String
});

var CommentSchema = new Schema({
  text: String,
  created_by: { type: Schema.Types.ObjectId, ref: 'User' }
});

var ItemSchema = new Schema({
   comments: [CommentSchema]
});

// Connect to DB and instantiate models    
var db = mongoose.connect('enter your database here');
var User = db.model('User', UserSchema);
var Comment = db.model('Comment', CommentSchema);
var Item = db.model('Item', ItemSchema);

// Find and populate
Item.find({}).populate('comments.created_by').exec(function(err, items) {
    console.log(items[0].comments[0].created_by.name);
});

Finally note that populate works only for queries so you need to first pass your item into a query and then call it:

item.save(function(err, item) {
    Item.findOne(item).populate('comments.created_by').exec(function (err, item) {
        res.json({
            status: 'success',
            message: "You have commented on this item",
            comment: item.comments.id(comment._id)
        });
    });
});

You also need to set the option CURLOPT_COOKIEFILE.

The manual describes this as

The name of the file containing the cookie data. The cookie file can be in Netscape format, or just plain HTTP-style headers dumped into a file. If the name is an empty string, no cookies are loaded, but cookie handling is still enabled.

Since you are using the cookie jar you end up saving the cookies when the requests finish, but since the CURLOPT_COOKIEFILE is not given, cURL isn't sending any of the saved cookies on subsequent requests.

(tomcat 8.0.28) Above method did not work for me. This is what worked:

1. Add this line to the end of your {CATALINA-HOME}/conf/logging.properties:

   org.apache.jasper.level = FINEST
   

2. Shut down the server (if started).

3. Open console and run (in case of Windows):

   %CATALINA_HOME%\bin\catalina.bat run
   

4. Enjoy logs, e.g. (again, for Windows):

   {CATALINA-HOME}/logs/catalina.2015-12-28.log
   

I gave up on integrating this with Eclipse launch configuration so be aware that this works only from console, launching the server from Eclipse won't produce additional log messages.

You can get the same error in Asp.net MVC5 if you have a class name and a folder with a matching name Example : If you have class lands where when you want to see view/lands/index.cshtml file, if you also have a folder with name 'lands' you get the error as it first try the lands folder

grant all on newdb.* to newuser@localhost identified by 'password';

Check the information in registry : HKEY_CURRENT_USER\SOFTWARE\Microsoft\VSCommon\Keychain\Accounts and delete the related keys under Accounts section.

Clear the cache in these paths:

• %localappdata%\Microsoft\TeamTest

• %localappdata%\Microsoft\Team Foundation

• %localappdata%\Microsoft\VisualStudio

• %appdata%\Roaming\Microsoft\VisualStudio

Hope this will work.

Note: By doing this may clear all the cookies and caches and load the Visual Studio New.

I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).

A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.

Do like this:

create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;

First make sure you have SessionMiddleware and AuthenticationMiddleware middlewares added to your MIDDLEWARE_CLASSES setting.

The current user is in request object, you can get it by:

def sample_view(request):
    current_user = request.user
    print current_user.id

request.user will give you a User object representing the currently logged-in user. If a user isn't currently logged in, request.user will be set to an instance of AnonymousUser. You can tell them apart with the field is_authenticated, like so:

if request.user.is_authenticated:
    # Do something for authenticated users.
else:
    # Do something for anonymous users.

sudo apt-get install ruby-dev

worked for me

I could solve my issue rearding this problem by killing explorer.exe which in turn was addicted to the process I wanted to kill. I guess this may also happen if processes open interfaces via hook which may be locked.

Right click on the file with file explorer, choose Properties, then General tab and click on the Unblock button. This error message is very misleading.

Instead of a button, put a link and navigate it to another page

<a href="logout.php">Logout</a>

Then in logout.php page, use

session_start();
session_destroy();
header('Location: login.php');
exit;

Use console.dir() to output a browse-able object you can click through instead of the .toString() version, like this:

console.dir(obj/this/anything)

How to show full object in Chrome console?

I know you've found another solution, but for those like me who find this question, looking for the same thing, it can be achieved with requests as follows:

Firstly, as Marcus did, check the source of the login form to get three pieces of information - the url that the form posts to, and the name attributes of the username and password fields. In his example, they are inUserName and inUserPass.

Once you've got that, you can use a requests.Session() instance to make a post request to the login url with your login details as a payload. Making requests from a session instance is essentially the same as using requests normally, it simply adds persistence, allowing you to store and use cookies etc.

Assuming your login attempt was successful, you can simply use the session instance to make further requests to the site. The cookie that identifies you will be used to authorise the requests.

Example

import requests

# Fill in your details here to be posted to the login form.
payload = {
    'inUserName': 'username',
    'inUserPass': 'password'
}

# Use 'with' to ensure the session context is closed after use.
with requests.Session() as s:
    p = s.post('LOGIN_URL', data=payload)
    # print the html returned or something more intelligent to see if it's a successful login page.
    print p.text

    # An authorised request.
    r = s.get('A protected web page url')
    print r.text
        # etc...

Another solution is to user axios:

npm install axios

Code will be like:

const url = `${this.env.someMicroservice.address}/v1/my-end-point`;

const { data } = await axios.get<MyInterface>(url, {
  auth: {
    username: this.env.auth.user,
    password: this.env.auth.pass
  }
});

return data;

So, in addition to Adam Rackis' answer, if you have errors in your javascript file above the breakpoint, you won't reach it regardless if you flag it, or put in debugger;.

Here's an example:

if (nonExistentVar === "something") {
  console.log("this won't happen as the above errors out");
}
debugger;
console.log("this won't print either")

Are you logging into MySQL as root? You have to explicitly grant privileges to your "regular" MySQL user account while logged in as MySQL root.

First set up a root account for your MySQL database.

In the terminal type:

mysqladmin -u root password 'password'

To log into MySQL, use this:

mysql -u root -p

To set the privileges manually start the server with the skip-grant-tables option, open mysql client and manually update the mysql.user table and/or the mysql.db tables. This can be a tedious task though so if what you need is an account with all privs I would do the following.

Start the server with the skip-grant-tables option

Start mysql client (without a username/password)

Issue the command

flush privileges;

which forces the grant tables to be loaded.

Create a new account with the GRANT command something like this (but replacing username and password with whatever you want to use.

GRANT ALL on *.* to 'username'@'localhost' identified by 'password';

Restart the server in normal mode (without skip-grant-tables) and log in with your newly created account.

Refer this MySQL docs.

An other solution rm(list=ls(pattern="temp")), remove all objects matching the pattern.

mysql_fetch_assoc returns an array so you can not echo an array, need to print_r() otherwise particular string $money['money'].

If you do not want to use angular-ui-router, but would like to have your controllers lazy loaded via RequireJS, there are couple of problems with event $routeChangeStart when using your controllers as RequireJS modules (lazy loaded).

You cannot be sure the controller will be loaded before $routeChangeStart gets triggered -- in fact it wont be loaded. That means you cannot access properties of next route like locals or $$route because they are not yet setup.
Example:

app.config(["$routeProvider", function($routeProvider) {
    $routeProvider.when("/foo", {
        controller: "Foo",
        resolve: {
            controller: ["$q", function($q) {
                var deferred = $q.defer();
                require(["path/to/controller/Foo"], function(Foo) {
                    // now controller is loaded
                    deferred.resolve();
                });
                return deferred.promise;
            }]
        }
    });
}]);

app.run(["$rootScope", function($rootScope) {
    $rootScope.$on("$routeChangeStart", function(event, next, current) {
        console.log(next.$$route, next.locals); // undefined, undefined
    });
}]);

This means you cannot check access rights in there.

Solution:

As loading of controller is done via resolve, you can do the same with your access control check:

app.config(["$routeProvider", function($routeProvider) {
    $routeProvider.when("/foo", {
        controller: "Foo",
        resolve: {
            controller: ["$q", function($q) {
                var deferred = $q.defer();
                require(["path/to/controller/Foo"], function(Foo) {
                    // now controller is loaded
                    deferred.resolve();
                });
                return deferred.promise;
            }],
            access: ["$q", function($q) {
                var deferred = $q.defer();
                if (/* some logic to determine access is granted */) {
                    deferred.resolve();
                } else {
                    deferred.reject("You have no access rights to go there");
                }
                return deferred.promise;
            }],
        }
    });
}]);

app.run(["$rootScope", function($rootScope) {
    $rootScope.$on("$routeChangeError", function(event, next, current, error) {
        console.log("Error: " + error); // "Error: You have no access rights to go there"
    });
}]);

Note here that instead of using event $routeChangeStart I'm using $routeChangeError

My problem was on my KSWEB app that I downloaded. I am having no privileges error, but when I opened my config.inc.php and changed

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

to

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

It worked and I now have privileges to create a database.

The correct way to connect to remote SQL Server (without opening UDP port 1434 and enabling SQL Server Browser) is to use ip and port instead of named instance.

Using ip and port instead of named instance is also safer, as it reduces the attack surface area.

Perhaps 2 pictures speak 2000 words...

This method uses the specified port (this is what most people want I believe)..

This method requires opening UDP port 1434 and SQL Server Browser running..

I had the same issue in case of CentOS 7. I went through lot of articles ,forums but couldnt find out the solution. The problem was with SElinux. Disabling SElinux at the server end worked. Check SELinux status at the server end (from where you are pulling data using rysnc) Commands to check SELinux status and disable it

$getenforce

Enforcing ## this means SElinux is enabled

$setenforce 0

$getenforce

Permissive

Now try running rsync command at the client end ,it worked for me. All the best!

The below are the typical situation where we shall get ERR_FILE_NOT_FOUND even file avail in respective folder.

Code:
@font-face {
    font-family: Eau_Sans_Bold;
    src: url("/fonts/eau_sans_bold.otf") format("opentype");
}
Error:
 GET file:///C:/fonts/eau_sans_bold.otf net::ERR_FILE_NOT_FOUND

Answer or Solution.:
@font-face {
    font-family: Eau_Sans_Book;
    src: url("../fonts/eau_sans_book.otf") format("opentype");  
}

Basically browser not able to pick if we metion just /font/. We should to mention ../fonts/ This will work. So, we wont get ERR_FILE_NOT_FOUND.

I dont know why but it worked for me. If you have comments like

//Comment

Then it gives this error. To fix this do

/*Comment*/

Doesn't make sense but it worked for me.

I had the same issue for a specific controller only - which was really weird. I had a folder in the root of the CI folder that had the same name as the controller I was trying to access... Because of that, CI was directing the request to this directory instead of the controller itself.

After removing this folder (which was there a bit by mistake), it all worked fine.

To be more clear, here is what it looked like:

/ci/controller/register.php

/ci/register/

I had to remove /ci/register/.

You are casting ClientID to char* causing the function to assume its a null terinated char array, which it is not.

from cplusplus.com :

string& append ( const char * s ); Appends a copy of the string formed by the null-terminated character sequence (C string) pointed by s. The length of this character sequence is determined by the first ocurrence of a null character (as determined by traits.length(s)).

open a terminal and enter

node -v

this will tell you the version of the nodejs installed, then run nodejs simple by entering

node

Prompt must be change. Enter following,

function testNode() {return "Node is working"}; testNode();

command line must prompt the following output if the installation was successful

'Node is working'

If you are using security annotation from the SensioFrameworkExtraBundle, you can use a few expressions (that are defined in \Symfony\Component\Security\Core\Authorization\ExpressionLanguageProvider):

• @Security("is_authenticated()"): to check that the user is authed and not anonymous
• @Security("is_anonymous()"): to check if the current user is the anonymous user
• @Security("is_fully_authenticated()"): equivalent to is_granted('IS_AUTHENTICATED_FULLY')
• @Security("is_remember_me()"): equivalent to is_granted('IS_AUTHENTICATED_REMEMBERED')

On properties,

Check whether radio button is selected for

Run only when user is logged on 

If you selected for the above option then that is the reason why it is failed.

so change the option to

Run whether user is logged on or not

OR

In other case, user might have changed his/her login credentials

//start use session

$session_start();

extract($_POST);         
//extract data from submit post 

if(isset($submit))  
{

if($user=="user" && $pass=="pass")

{

$_SESSION['user']= $user;   

//if correct password and name store in session 

}
else {

echo "Invalid user and password";

header("Locatin:form.php");

}

if(isset($_SESSION['user'])) 

{

//your home page code here

exit;
}

It depends on the server configuration or the relevant directives session.gc_maxlifetime in php.ini.

Typically the default is 24 minutes (1440 seconds), but your webhost may have altered the default to something else.

Queries should look like :

SHOW TABLES

SHOW TABLES FROM mydatabase

SHOW TABLES FROM mydatabase LIKE "tab%"

Things from the MySQL documentation in square brackets [] are optional.

The answer is on the MSDN site:

The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.

The following actions might require a table to be re-created:

• Adding a new column to the middle of the table
• Dropping a column
• Changing column nullability
• Changing the order of the columns
• Changing the data type of a column

EDIT 1:

Additional useful informations from here:

To change the Prevent saving changes that require the table re-creation option, follow these steps:

1. Open SQL Server Management Studio (SSMS).
2. On the Tools menu, click Options.
3. In the navigation pane of the Options window, click Designers.
4. Select or clear the Prevent saving changes that require the table re-creation check box, and then click OK.

Note If you disable this option, you are not warned when you save the table that the changes that you made have changed the metadata structure of the table. In this case, data loss may occur when you save the table.

Risk of turning off the "Prevent saving changes that require table re-creation" option

Although turning off this option can help you avoid re-creating a table, it can also lead to changes being lost. For example, suppose that you enable the Change Tracking feature in SQL Server 2008 to track changes to the table. When you perform an operation that causes the table to be re-created, you receive the error message that is mentioned in the "Symptoms" section. However, if you turn off this option, the existing change tracking information is deleted when the table is re-created. Therefore, we recommend that you do not work around this problem by turning off the option.

You can also use Requestify, a really cool and very simple HTTP client I wrote for nodeJS + it supports caching.

Just do the following for executing a POST request:

var requestify = require('requestify');

requestify.post('http://example.com', {
    hello: 'world'
})
.then(function(response) {
    // Get the response body (JSON parsed or jQuery object for XMLs)
    response.getBody();
});

I wrote telegram bot, and have some problem with update rows. Use this example, if you have Model

def update_state(chat_id, state):
    try:
        value = Users.query.filter(Users.chat_id == str(chat_id)).first()
        value.state = str(state)
        db.session.flush()
        db.session.commit()
        #db.session.close()
    except:
        print('Error in def update_state')

Why use db.session.flush()? That's why >>> SQLAlchemy: What's the difference between flush() and commit()?

One time fix :

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers]
"C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\Common7\\IDE\\devenv.exe"="~ RUNASADMIN"

For me it was fixed by just removing the static property in the DialogHelper.class methods (resposble for creating & hiding the dialog), as I have properties related to Window in those methods

Execute chmod 777 -R scripts/, it worked fine for me ;)

This is the RegKey I used:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor]
"DisableUNCCheck"=dword:00000001

this may help you.

In .cs page,

//Declare a string
   public string usertypeurl = "";
  //check who is the user
       //place your code to check who is the user
       //if it is admin
       usertypeurl = "help/AdminTutorial.html";
       //if it is other 
        usertypeurl = "help/UserTutorial.html";

In .aspx age pass this variabe

  <a href='<%=usertypeurl%>'>Tutorial</a>

Felt compelled to answer this because of the other responses. Use empty() if you can because it covers more bases. Future you will thank me.

For example you will have to do things like isset() && strlen() where instead you could use empty(). Think of it like this empty is like !isset($var) || $var==false

You can try this: By Using Authentication Object from Spring we can get User details from it in the controller method . Below is the example , by passing Authentication object in the controller method along with argument.Once user is authenticated the details are populated in the Authentication Object.

@GetMapping(value = "/mappingEndPoint") <ReturnType> methodName(Authentication auth) {
   String userName = auth.getName(); 
   return <ReturnType>;
}

The option is called Modify:

This will show you the T-SQL code for your stored procedure in a new query window, with an ALTER PROCEDURE ... lead-in, so you can easily change or amend your procedure and update it

Notice how the output of

SHOW GRANTS FOR 'root'@'localhost';

did not say 'ALL PRIVILEGES' but had to spell out what root@localhost has.

GRANT ALL PRIVILEGES will fail, because a user can not grant what he/she does not have, and the server seem to think something is not here ...

Now, what's missing then ?

There are also new tables in 5.5, such as mysql.proxies_user: make sure you have them.

When installing a brand new mysql server instance, the install script will create all the mysql.* tables with the proper structure.

When upgrading from an old version, make sure the proper upgrade procedure (mysql_upgrade) is used, which will add the missing tables / columns.

It is only a guess, but it seems mysql_upgrade was not done for this instance, causing the behavior seen.

Since Result Set is an interface, When you obtain a reference to a ResultSet through a JDBC call, you are getting an instance of a class that implements the ResultSet interface. This class provides concrete implementations of all of the ResultSet methods.

Interfaces are used to divorce implementation from, well, interface. This allows the creation of generic algorithms and the abstraction of object creation. For example, JDBC drivers for different databases will return different ResultSet implementations, but you don't have to change your code to make it work with the different drivers

In very short, if your ResultSet contains result, then using rs.next return true if you have recordset else it returns false.

Just telling my resolution: in my case, the libraries and projects weren't being added automatically to the classpath (i don't know why), even clicking at the "add to build path" option. So I went on run -> run configurations -> classpath and added everything I needed through there.

1. Use HTTP Basic Auth to authenticate clients, but treat username/password only as temporary session token.
   
   The session token is just a header attached to every HTTP request, eg: Authorization: Basic Ym9ic2Vzc2lvbjE6czNjcmV0
   
   The string Ym9ic2Vzc2lvbjE6czNjcmV0 above is just the string "bobsession1:s3cret" (which is a username/password) encoded in Base64.

2. To obtain the temporary session token above, provide an API function (eg: http://mycompany.com/apiv1/login) which takes master-username and master-password as an input, creates a temporary HTTP Basic Auth username / password on the server side, and returns the token (eg: Ym9ic2Vzc2lvbjE6czNjcmV0). This username / password should be temporary, it should expire after 20min or so.

3. For added security ensure your REST service are served over HTTPS so that information are not transferred plaintext

If you're on Java, Spring Security library provides good support to implement above method

My approach, i think coming more from an development than an operations point of view, is:

• Error means that the execution of some task could not be completed; an email couldn't be sent, a page couldn't be rendered, some data couldn't be stored to a database, something like that. Something has definitively gone wrong.
• Warning means that something unexpected happened, but that execution can continue, perhaps in a degraded mode; a configuration file was missing but defaults were used, a price was calculated as negative, so it was clamped to zero, etc. Something is not right, but it hasn't gone properly wrong yet - warnings are often a sign that there will be an error very soon.
• Info means that something normal but significant happened; the system started, the system stopped, the daily inventory update job ran, etc. There shouldn't be a continual torrent of these, otherwise there's just too much to read.
• Debug means that something normal and insignificant happened; a new user came to the site, a page was rendered, an order was taken, a price was updated. This is the stuff excluded from info because there would be too much of it.
• Trace is something i have never actually used.

Following should work. I have verified. May be your problem is somewhere else.

You can do it like that 2>&1:

 command > file 2>&1

1. Open Reg HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\

2. make a loop to get all subkeys

3. the subkeys you are interested with are those started with [S-1-5-21-] which means user (see key name [ProfileImagePath] they are always started with a path c:\Users)

4. Those starting with [S-1-5-21-12] are all local users

5. Those starting with [S-1-5-21-13] are all network users [if joined to Domained network] that are previously logged on the machine.

Why Server.Transfer? Response.Redirect(Request.RawUrl) would get you what you need.

Use getpass for this purpose.

getpass.getpass - Prompt the user for a password without echoing

They have a different human-readable meaning.

However, depending on the query optimizer, they may have the same meaning to the machine.

You should always code to be readable.

That is to say, if this is a built-in relationship, use the explicit join. if you are matching on weakly related data, use the where clause.

From man curl:

-x, --proxy <[protocol://][user:password@]proxyhost[:port]>

     Use the specified HTTP proxy. 
     If the port number is not specified, it is assumed at port 1080.

General way:

export http_proxy=http://your.proxy.server:port/

Then you can connect through proxy from (many) application.

And, as per comment below, for https:

export https_proxy=https://your.proxy.server:port/

There are a few things to change in your edited version:

1. You've taken the suggestion of using document.myform['whichThing'] a bit too literally. Your form is named "aye", so the code to access the whichThing radio buttons should use that name: `document.aye['whichThing'].

2. There's no such thing as an action attribute for the <input> tag. Use onclick instead: <input name="Submit" type="submit" value="Update" onclick="handleClick();return false"/>

3. Obtaining and cancelling an Event object in a browser is a very involved process. It varies a lot by browser type and version. IE and Firefox handle these things very differently, so a simple event.preventDefault() won't work... in fact, the event variable probably won't even be defined because this is an onclick handler from a tag. This is why Stephen above is trying so hard to suggest a framework. I realize you want to know the mechanics, and I recommend google for that. In this case, as a simple workaround, use return false in the onclick tag as in number 2 above (or return false from the function as stephen suggested).

4. Because of #3, get rid of everything not the alert statement in your handler.

The code should now look like:

function handleClick()
      {
        alert("Favorite weird creature: "+getRadioButtonValue(document.aye['whichThing']));
      }
    </script>
  </head>
<body>
    <form name="aye">
      <input name="Submit"  type="submit" value="Update" onclick="handleClick();return false"/>
      Which of the following do you like best?
      <p><input type="radio" name="whichThing" value="slithy toves" />Slithy toves</p>
      <p><input type="radio" name="whichThing" value="borogoves" />Borogoves</p>
      <p><input type="radio" name="whichThing" value="mome raths" />Mome raths</p>
    </form>

You need to understand CommonJS, which is a pattern to define modules. You shouldn't abuse GLOBAL scope that's always a bad thing to do, instead you can use the 'exports' token, like this:

// circle.js

var PI = 3.14; // PI will not be accessible from outside this module

exports.area = function (r) {
  return PI * r * r;
};

exports.circumference = function (r) {
  return 2 * PI * r;
};

And the client code that will use our module:

// client.js

var circle = require('./circle');
console.log( 'The area of a circle of radius 4 is '
           + circle.area(4));

This code was extracted from node.js documentation API:

http://nodejs.org/docs/v0.3.2/api/modules.html

Also, if you want to use something like Rails or Sinatra, I recommend Express (I couldn't post the URL, shame on Stack Overflow!)

Use the square bracket syntax:

if (!empty($row["title"])) {
    $catList[$row["datasource_id"]] = $row["title"];
}

$row["datasource_id"] is the key for where the value of $row["title"] is stored in.

In my case got a working solution through Cross-document Messaging (XDM) and Executing Chrome extension onclick instead of page load.

manifest.json

{
  "name": "JQuery Light",
  "version": "1",
  "manifest_version": 2,

  "browser_action": {
    "default_icon": "icon.png"
  },

  "content_scripts": [
    {
      "matches": [
        "https://*.google.com/*"
      ],
      "js": [
        "jquery-3.3.1.min.js",
        "myscript.js"
      ]
    }
  ],

  "background": {
    "scripts": [
      "background.js"
    ]
  }

}

background.js

chrome.browserAction.onClicked.addListener(function (tab) {
  chrome.tabs.query({active: true, currentWindow: true}, function (tabs) {
    var activeTab = tabs[0];
    chrome.tabs.sendMessage(activeTab.id, {"message": "clicked_browser_action"});
  });
});

myscript.js

chrome.runtime.onMessage.addListener(
    function (request, sender, sendResponse) {
        if (request.message === "clicked_browser_action") {
        console.log('Hello world!')
        }
    }
);

You could also use inline blocks to avoid floating elements

<ul>
    <li>
        <a href="#">some item</a>
    </li>
    <li>
        <a href="#">another item</a>
   </li>
</ul>

and then style as:

li{
    /* with fix for IE */
    display:inline;
    display:inline-block;
    zoom:1;
    /*
    additional styles to make it look nice
    */
 }

that way you wont need to float anything, eliminating the need for clearfixes

Try this:

x = a > b and 10 or 11

This is a sample of execution:

>>> a,b=5,7
>>> x = a > b and 10 or 11
>>> print x
11

Try closing and reopening the file, then press Ctrl+F11.

Verify that the name of the file you are running is the same as the name of the project you are working in, and that the name of the public class in that file is the same as the name of the project you are working in as well.

Otherwise, restart Eclipse. Let me know if this solves the problem! Otherwise, comment, and I'll try and help.

That is not what the error message says. It says that you cannot use the = operator. Try for instance LIKE 'foo'.

If you want to be a good citizen, take the extra time to implement Parcelable since it will perform 10 times faster and use less resources.

However, in most cases, the slowness of Serializable won’t be noticeable. Feel free to use it but remember that serialization is an expensive operation so keep it to a minimum.

If you are trying to pass a list with thousands of serialized objects, it is possible that the whole process will take more than a second. It can make transitions or rotation from portrait to lanscape feel very sluggish.

I haven't done any benchmarks, but this recipe "works for me".

The short version: use '%x' % val, then unhexlify the result. The devil is in the details, though, as unhexlify requires an even number of hex digits, which %x doesn't guarantee. See the docstring, and the liberal inline comments for details.

from binascii import unhexlify

      big-endian, ``'little'`` for little-endian.

    width += 8 - ((width % 8) or 8)

Timing approach is wrong - how do you know how long the action will take on client's browser?

How to do it

$('form').submit(function(){
  $(this).find(':submit').attr('disabled','disabled');
});

When form is submitted it will disable all submit buttons inside.

Remember, in Firefox when you disable a button this state will be remembered when you go back in history. To prevent that you have to enable buttons on page load, for example.

You can also use JSONObject class from json.org to this will convert your HashMap to JSON string which is well formatted

Example:

Map<String,Object> map = new HashMap<>();
map.put("myNumber", 100);
map.put("myString", "String");

JSONObject json= new JSONObject(map);

String result= json.toString();

System.out.print(result);

result:

{'myNumber':100, 'myString':'String'}

Your can also get key from it like

System.out.print(json.get("myNumber"));

result:

100

/**

public static Document string2Document(String xml) throws IOException, SAXException, ParserConfigurationException {

    if (xml == null)
    return null;

    return inputStream2Document(new ByteArrayInputStream(xml.getBytes()));

}


/**

* @param inputStream The inputstream to convert

public static Document inputStream2Document(InputStream inputStream) throws IOException, SAXException, ParserConfigurationException {
    DocumentBuilderFactory newInstance = DocumentBuilderFactory.newInstance();
    newInstance.setNamespaceAware(true);
    Document parse = newInstance.newDocumentBuilder().parse(inputStream);
    return parse;
}

Actually the default value of byte is 0.

in case of the IPv4 protocol, the server with one IP address that listens on one port only can handle 2^32 IP addresses x 2^16 ports so 2^48 unique sockets. If you speak about a server as a physical machine, and you are able to utilize all 2^16 ports, then there could be maximum of 2^48 x 2^16 = 2^64 unique TCP/IP sockets for one IP address. Please note that some ports are reserved for the OS, so this number will be lower. To sum up:

1 IP and 1 port --> 2^48 sockets

1 IP and all ports --> 2^64 sockets

all unique IPv4 sockets in the universe --> 2^96 sockets

Use Enumerable.Select<TSource, TResult> Method (IEnumerable<TSource>, Func<TSource, Int32, TResult>)

list = list.Cast<object>().Select( (v, i) => new {Value= v, Index = i});

foreach(var row in list)
{
    bool IsChecked = (bool)((CheckBox)DataGridDetail.Columns[0].GetCellContent(row.Value)).IsChecked;
    row.Index ...
}

It is true that it is always possible to reverse engineer some code, just like it is impossible to protect a house in order so nobody can ever steal from it. That does not keep me from locking the door, though. Actually, I am not in the java world, I use BitHelmet for .net.

use

LDFLAGS= -L<Directory where the library resides> -l<library name>

Like :

LDFLAGS = -L. -lmine

for ensuring static compilation you can also add

LDFLAGS = -static

Or you can just get rid of the whole library searching, and link with with it directly.

say you have main.c fun.c

and a static library libmine.a

then you can just do in your final link line of the Makefile

$(CC) $(CFLAGS) main.o fun.o libmine.a

Check out the addressable gem - a popular replacement for Ruby's URI module that makes query parsing easy:

require "addressable/uri"
uri = Addressable::URI.parse("http://www.example.com/something?param1=value1&param2=value2&param3=value3")
uri.query_values['param1']
=> 'value1'

(It also apparently handles param encoding/decoding, unlike URI)

Have you considering using the Maven command-line to upload files?

mvn deploy:deploy-file \
    -Durl=$REPO_URL \
    -DrepositoryId=$REPO_ID \
    -DgroupId=org.myorg \
    -DartifactId=myproj \
    -Dversion=1.2.3  \
    -Dpackaging=zip \
    -Dfile=myproj.zip

This will automatically generate the Maven POM for the artifact.

Update

The following Sonatype article states that the "deploy-file" maven plugin is the easiest solution, but it also provides some examples using curl:

https://support.sonatype.com/entries/22189106-How-can-I-programatically-upload-an-artifact-into-Nexus-

Sometimes this issue come because of space in PHP start tag of controller facing same issue just removed whitespace in:

I would recommend using the great Joda-Time library for everything date related in Java.

For your needs you can use the Years.yearsBetween() method.

This worked for me, use the VM args in NetBeans:

@Value("${a.b.c:#{abc}}"
...

@Value("${e.f.g:#{efg}}"
...

Netbeans:

-Da.b.c="..." -De.f.g="..."

Properties -> Run -> VM Options -> -De.f.g=efg -Da.b.c=abc

From the commandline

java -jar <yourjar> --Da.b.c="abc" 

This is a simple example of what I used for a recent test. You need to make sure that your security settings are the same on the server and client.

var myBinding = new BasicHttpBinding();
myBinding.Security.Mode = BasicHttpSecurityMode.None;
var myEndpointAddress = new EndpointAddress("http://servername:8732/TestService/");
client = new ClientTest(myBinding, myEndpointAddress);
client.someCall();

If you create a new Date object, by default it will be set to the current time:

import java.util.Date;
Date now = new Date();

To get something like this

with Bootstrap 3 and Jquery use the following HTML code:

<div class="btn-group">
  <input id="searchinput" type="search" class="form-control">
  <span id="searchclear" class="glyphicon glyphicon-remove-circle"></span>
</div>

and some CSS:

#searchinput {
    width: 200px;
}
#searchclear {
    position: absolute;
    right: 5px;
    top: 0;
    bottom: 0;
    height: 14px;
    margin: auto;
    font-size: 14px;
    cursor: pointer;
    color: #ccc;
}

and Javascript:

$("#searchclear").click(function(){
    $("#searchinput").val('');
});

Of course you have to write more Javascript for whatever functionality you need, e.g. to hide the 'x' if the input is empty, make Ajax requests and so on. See http://www.bootply.com/121508

I find this code useful when I need a path outside of a controller, such as when I'm initializing components in Global.asax.cs:

HostingEnvironment.MapPath("~/Data/data.html")

The StringBuilder.Append() method is much better than using the + operator. But I've found that, when executing 1000 concatenations or less, String.Join() is even more efficient than StringBuilder.

StringBuilder sb = new StringBuilder();
sb.Append(someString);

The only problem with String.Join is that you have to concatenate the strings with a common delimiter.

Edit: as @ryanversaw pointed out, you can make the delimiter string.Empty.

string key = String.Join("_", new String[] 
{ "Customers_Contacts", customerID, database, SessionID });

This should work as tested.

<?php
$filter = new Mage_Widget_Model_Template_Filter();
$_widget = $filter->filter('{{widget type="cms/widget_page_link" template="cms/widget/link/link_block.phtml" page_id="2"}}');
echo $_widget;
?>

When you want to destroy a session completely, you need to do more then just

session_destroy();

First, you should unset any session variables. Then you should destroy the session followed by closing the write of the session. This can be done by the following:

<?php
session_start();
unset($_SESSION);
session_destroy();
session_write_close();
header('Location: /');
die;
?>

The reason you want have a separate script for a logout is so that you do not accidently execute it on the page. So make a link to your logout script, then the header will redirect to the root of your site.

Edit:

You need to remove the () from your exit code near the top of your script. it should just be

exit;

Mini tip:

I had the following scenario:

<a href="/page/">My link text
:after
</a>

I hided the text with font-size: 0, so I could use a FontAwesome icon for it. This worked on Chrome 36, Firefox 31 and IE9+.

I wouldn't recommend color: transparent because the text stil exists and is selectable. Using line-height: 0px didn't allow me to use :after. Maybe because my element was a inline-block.

Visibility: hidden: Didn't allow me to use :after.

text-indent: -9999px;: Also moved the :after element

Try and retrieve the text property of the link button in the code behind:

protected void ENameLinkBtn_Click (object sender, EventArgs e)
{
   string val = ((LinkButton)sender).Text
}

To remove duplicates from a single column

 Sub removeDuplicate()
 'removeDuplicate Macro
 Columns("A:A").Select
 ActiveSheet.Range("$A$1:$A$117").RemoveDuplicates Columns:=Array(1), _ 
 Header:=xlNo 
 Range("A1").Select
 End Sub

if you have header then use Header:=xlYes

Increase your range as per your requirement.
you can make it to 1000 like this :

ActiveSheet.Range("$A$1:$A$1000")

AppStartListener implements ApplicationListener {
    @Override
    public void onApplicationEvent(ApplicationEvent event) {
        if(event instanceof ApplicationReadyEvent){
            System.out.print("ciao");

        }
    }
}

Something like this should remove it

document.getElementById('x').style.visibility='hidden';

If you are going to do alot of this dom manipulation might be worth looking at jquery

I wrote a class that implemented the GDI method for screen capture. I too wanted extra speed so, after discovering the DirectX method (via GetFrontBuffer) I tried that, expecting it to be faster.

I was dismayed to find that GDI performs about 2.5x faster. After 100 trials capturing my dual monitor display, the GDI implementation averaged 0.65s per screen capture, while the DirectX method averaged 1.72s. So GDI is definitely faster than GetFrontBuffer, according to my tests.

I was unable to get Brandrew's code working to test DirectX via GetRenderTargetData. The screen copy came out purely black. However, it could copy that blank screen super fast! I'll keep tinkering with that and hope to get a working version to see real results from it.

There are already many good answers to the part "what is uintptr_t data type". I will try to address the "what it can be used for?" part in this post.

Primarily for bitwise operations on pointers. Remember that in C++ one cannot perform bitwise operations on pointers. For reasons see Why can't you do bitwise operations on pointer in C, and is there a way around this?

Thus in order to do bitwise operations on pointers one would need to cast pointers to type unitpr_t and then perform bitwise operations.

Here is an example of a function that I just wrote to do bitwise exclusive or of 2 pointers to store in a XOR linked list so that we can traverse in both directions like a doubly linked list but without the penalty of storing 2 pointers in each node.

 template <typename T>
 T* xor_ptrs(T* t1, T* t2)
 {
     return reinterpret_cast<T*>(reinterpret_cast<uintptr_t>(t1)^reinterpret_cast<uintptr_t>(t2));
  }

Here is a rough but more declarative solution. I haven't been able to get it down to a single annotation, but this seems to work well. Also not sure about performance on large data sets.

Given this JSON:

{
    "list": [
        {
            "wrapper": {
                "name": "Jack"
            }
        },
        {
            "wrapper": {
                "name": "Jane"
            }
        }
    ]
}

And these model objects:

public class RootObject {
    @JsonProperty("list")
    @JsonDeserialize(contentUsing = SkipWrapperObjectDeserializer.class)
    @SkipWrapperObject("wrapper")
    public InnerObject[] innerObjects;
}

and

public class InnerObject {
    @JsonProperty("name")
    public String name;
}

Where the Jackson voodoo is implemented like:

@Retention(RetentionPolicy.RUNTIME)
@JacksonAnnotation
public @interface SkipWrapperObject {
    String value();
}

and

public class SkipWrapperObjectDeserializer extends JsonDeserializer<Object> implements
        ContextualDeserializer {
    private Class<?> wrappedType;
    private String wrapperKey;

    public JsonDeserializer<?> createContextual(DeserializationContext ctxt,
            BeanProperty property) throws JsonMappingException {
        SkipWrapperObject skipWrapperObject = property
                .getAnnotation(SkipWrapperObject.class);
        wrapperKey = skipWrapperObject.value();
        JavaType collectionType = property.getType();
        JavaType collectedType = collectionType.containedType(0);
        wrappedType = collectedType.getRawClass();
        return this;
    }

    @Override
    public Object deserialize(JsonParser parser, DeserializationContext ctxt)
            throws IOException, JsonProcessingException {
        ObjectMapper mapper = new ObjectMapper();
        ObjectNode objectNode = mapper.readTree(parser);
        JsonNode wrapped = objectNode.get(wrapperKey);
        Object mapped = mapIntoObject(wrapped);
        return mapped;
    }

    private Object mapIntoObject(JsonNode node) throws IOException,
            JsonProcessingException {
        JsonParser parser = node.traverse();
        ObjectMapper mapper = new ObjectMapper();
        return mapper.readValue(parser, wrappedType);
    }
}

Hope this is useful to someone!

If you do not want to specify a message with your stashed changes, pass the filename after a double-dash.

$ git stash -- filename.ext

If it's an untracked/new file, you will have to stage it first.

However, if you do want to specify a message, use push.

git stash push -m "describe changes to filename.ext" filename.ext

Both methods work in git versions 2.13+

Try this:

or even

• If you create Makefile by yourself, go to

1. Select Project->Properties from the menu bar.
2. Click C/C++ Build on the left in the dialog that comes up.
3. Disable generate makefile automatically -> Under the Builder Settings tab on the right, check and make sure the "Build location" is correct (That location is where your Makefile)

• If you don't have Makefile -> You need Eclipse DS-5 to help you create Makefile

1. Select Project->Properties from the menu bar.
2. Click C/C++ Build on the left in the dialog that comes up.
3. Enable generate makefile automatically

I advise you create Makefile by your self

Whether to use a HashSet<> or List<> comes down to how you need to access your collection. If you need to guarantee the order of items, use a List. If you don't, use a HashSet. Let Microsoft worry about the implementation of their hashing algorithms and objects.

A HashSet will access items without having to enumerate the collection (complexity of O(1) or near it), and because a List guarantees order, unlike a HashSet, some items will have to be enumerated (complexity of O(n)).

The following will loop through the given directory recursively and list all the contents :

for d in /home/ubuntu/*; do echo "listing contents of dir: $d"; ls -l $d/; done

var classList = $(element).attr('class').split(/\s+/);
$(classList).each(function(index){

     //do something

I think that in real world scenarios a simple click handler is probably better than over-complicated command-based systems but you can do something like that:

using RelayCommand from this article http://msdn.microsoft.com/en-us/magazine/dd419663.aspx

public class MyCommands
{
    public static readonly ICommand CloseCommand =
        new RelayCommand( o => ((Window)o).Close() );
}

<Button Content="Close Window"
        Command="{X:Static local:MyCommands.CloseCommand}"
        CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, 
                           AncestorType={x:Type Window}}}"/>

Let's do a test with 2 examples:

    <?php    
    $memory = (int)ini_get("memory_limit"); // Display your current value in php.ini (for example: 64M)
    echo "original memory: ".$memory."<br>";
    ini_set('memory_limit','128M'); // Try to override the memory limit for this script
    echo "new memory:".$memory;
    }
    // Will display:
    // original memory: 64
    // new memory: 64
    ?>

The above example doesn't work for overriding the memory_limit value. But This will work:

    <?php
    $memory = (int)ini_get("memory_limit"); // get the current value
    ini_set('memory_limit','128'); // override the value
    echo "original memory: ".$memory."<br>"; // echo the original value
    $new_memory = (int)ini_get("memory_limit"); // get the new value
    echo "new memory: ".$new_memory;  // echo the new value
    // Will display:
    // original memory: 64
    // new memory: 128
    ?>

You have to place the ini_set('memory_limit','128M'); at the top of the file or at least before any echo.

As for me, suhosin wasn't the solution because it doesn't even appear in my phpinfo(), but this worked:

    <?php
    ini_set('memory_limit','2048M'); // set at the top of the file
    (...)
    ?>

I just encountered this on my parrot os and this is how I solved it.

sudo service mongodb start

select with no lock - will select records which may / may not going to be inserted. you will read a dirty data.

for example - lets say a transaction insert 1000 rows and then fails.

when you select - you will get the 1000 rows.

You can also just enter the website and:

1. Choose a repository you have write access to (example URL)
2. Click "Upload files"
3. Drag and drop a folder with files into the "Drag files here to add them to your repository" area.

The same limitation applies here: the folder must contain at least one file inside it.

You can enter these module class suffixes for any module to better control where it will show or be hidden.

Then fill up "New Key Store" form. If you wand to change .jnk file destination then chick on destination and give a name to get Ok button. After finishing it you will get "Key store password", "Key alias", "Key password" Press next and change your the destination folder. Then press finish, thats all. :)

I feel I need to clarify one very important thing, for others (like my co-worker) who came across this thread and got the wrong information.

The answer given ("Try decimal(9,2) or decimal(10,2) or whatever.") is correct, but the reason ("increase the number of digits before the decimal") is wrong.

decimal(p,s) and numeric(p,s) both specify a Precision and a Scale. The "precision" is not the number of digits to the left of the decimal, but instead is the total precision of the number.

For example: decimal(2,1) covers 0.0 to 9.9, because the precision is 2 digits (00 to 99) and the scale is 1. decimal(4,1) covers 000.0 to 999.9 decimal(4,2) covers 00.00 to 99.99 decimal(4,3) covers 0.000 to 9.999

You can easily use xml (from the Python standard library) to convert to a pandas.DataFrame. Here's what I would do (when reading from a file replace xml_data with the name of your file or file object):

import pandas as pd
import xml.etree.ElementTree as ET
import io

def iter_docs(author):
    author_attr = author.attrib
    for doc in author.iter('document'):
        doc_dict = author_attr.copy()
        doc_dict.update(doc.attrib)
        doc_dict['data'] = doc.text
        yield doc_dict

xml_data = io.StringIO(u'''\

etree = ET.parse(xml_data) #create an ElementTree object 
doc_df = pd.DataFrame(list(iter_docs(etree.getroot())))

If there are multiple authors in your original document or the root of your XML is not an author, then I would add the following generator:

def iter_author(etree):
    for author in etree.iter('author'):
        for row in iter_docs(author):
            yield row

and change doc_df = pd.DataFrame(list(iter_docs(etree.getroot()))) to doc_df = pd.DataFrame(list(iter_author(etree)))

Have a look at the ElementTree tutorial provided in the xml library documentation.

Okay, so if you're on the same boat as me and found that none of these solutions helped you, you most likely have a problem where NuGet (or any of those packages) is failing to install from the VSIX program due it calling a method that doesn't exist on your computer (not sure what .dll it's referencing), so try this out from the following post:

• Delete all instances of Visual Studio 2015- this includes all registry values.
• Install a version of Visual Studio older than Update 1 (RTM version.); this is available here.
• If you still get an error, try repairing just the Visual Studio 2015 program. This is what ultimately fixed it for me.

Hope this helped someone out. It's really frustrating that the installer's log file doesn't help at all. I had to look at the log file specific to NuGet, and that's where I noticed the error:

The installation was unable to install the extension to all the selected products. For more information, click on the install log link at the bottom of the dialog.

Method not found: 'System.Collections.Generic.IEnumerable`1 System.Security.Cryptography.X509Certificates.X509ChainStatus Microsoft.VisualStudio.ExtensionManager.IInstallableExtension.get_InvalidCertificateInformation()'.

If you just need to go from BitmapImage to Bitmap it's quite easy,

private Bitmap BitmapImage2Bitmap(BitmapImage bitmapImage)
    {
        return new Bitmap(bitmapImage.StreamSource);
    }

NumPy 1.7.0 (when numpy.pad was added) is pretty old now (it was released in 2013) so even though the question asked for a way without using that function I thought it could be useful to know how that could be achieved using numpy.pad.

It's actually pretty simple:

>>> import numpy as np
>>> a = np.array([[ 1.,  1.,  1.,  1.,  1.],
...               [ 1.,  1.,  1.,  1.,  1.],
...               [ 1.,  1.,  1.,  1.,  1.]])
>>> np.pad(a, [(0, 1), (0, 1)], mode='constant')
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

In this case I used that 0 is the default value for mode='constant'. But it could also be specified by passing it in explicitly:

>>> np.pad(a, [(0, 1), (0, 1)], mode='constant', constant_values=0)
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

Just in case the second argument ([(0, 1), (0, 1)]) seems confusing: Each list item (in this case tuple) corresponds to a dimension and item therein represents the padding before (first element) and after (second element). So:

[(0, 1), (0, 1)]
         ^^^^^^------ padding for second dimension
 ^^^^^^-------------- padding for first dimension

  ^------------------ no padding at the beginning of the first axis
     ^--------------- pad with one "value" at the end of the first axis.

In this case the padding for the first and second axis are identical, so one could also just pass in the 2-tuple:

>>> np.pad(a, (0, 1), mode='constant')
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

In case the padding before and after is identical one could even omit the tuple (not applicable in this case though):

>>> np.pad(a, 1, mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.]])

Or if the padding before and after is identical but different for the axis, you could also omit the second argument in the inner tuples:

>>> np.pad(a, [(1, ), (2, )], mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.]])

However I tend to prefer to always use the explicit one, because it's just to easy to make mistakes (when NumPys expectations differ from your intentions):

>>> np.pad(a, [1, 2], mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.]])

Here NumPy thinks you wanted to pad all axis with 1 element before and 2 elements after each axis! Even if you intended it to pad with 1 element in axis 1 and 2 elements for axis 2.

I used lists of tuples for the padding, note that this is just "my convention", you could also use lists of lists or tuples of tuples, or even tuples of arrays. NumPy just checks the length of the argument (or if it doesn't have a length) and the length of each item (or if it has a length)!

To make the change for one session, use this command:

:set tabstop=4

To make the change permanent, add it to ~/.vimrc or ~/.vim/vimrc:

set tabstop=4

This will affect all files, not just css. To only affect css files:

autocmd Filetype css setlocal tabstop=4

as stated in Michal's answer.

You must be providing the wrong path to the debug.keystore file.

Follow these steps to get the correct path and complete your command:

1. In eclipse, click the Window menu -> Preferences -> Expand Android -> Build
2. In the right panel, look for: Default debug keystore:
3. Select the entire box next to the label specified in Step 2

And finally, use the path you just copied from Step 3 to construct your command:

For example, in my case, it would be:

C:\Program Files\Java\jre7\bin>keytool -list -v -keystore "C:\Users\Siddharth Lele.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

UPDATED:

If you had already followed the steps mentioned above, the only other solution is to delete the debug.keystore and let Eclipse recreate it for you.

Step 1: Go to the path where your keystore is stored. In your case, C:\Users\Suresh\.android\debug.keystore

Step 2: Close and restart Eclipse.

Step 3 (Optional): You may need to clean your project before the debug.keystore is created again.

Source: http://www.coderanch.com/t/440920/Security/KeyTool-genkeypair-exception-Keystore-file

You can refer to this for the part about deleting your debug.keystore file: "Debug certificate expired" error in Eclipse Android plugins

It seems there is a much better and clean solution: To use google.maps.places.SearchBox instead of google.maps.places.Autocomplete. A code is almost the same, just getting the first from multiple places. On pressing the Enter the the correct list is returned - so it runs out of the box and there is no need for hacks.

See the example HTML page:

http://rawgithub.com/klokan/8408394/raw/5ab795fb36c67ad73c215269f61c7648633ae53e/places-enter-first-item.html

The relevant code snippet is:

var searchBox = new google.maps.places.SearchBox(document.getElementById('searchinput'));

google.maps.event.addListener(searchBox, 'places_changed', function() {
  var place = searchBox.getPlaces()[0];

  if (!place.geometry) return;

  if (place.geometry.viewport) {
    map.fitBounds(place.geometry.viewport);
  } else {
    map.setCenter(place.geometry.location);
    map.setZoom(16);
  }
});

The complete source code of the example is at: https://gist.github.com/klokan/8408394

check this, you should give arguments in msecs, Dont just send progress to seekTo(int)

and also check this getCurrentPostion() and getDuration().

You can do some calcuations, ie., convert progress in msec like msce = (progress/100)*getDuration() then do seekTo(msec)

Or else i have an easy idea, you don't need to change any code anywer else just add seekBar.setMax(mPlayer.getDuration()) once your media player is prepared.

and here is link exactly what you want seek bar update

Internal will allow you to reference, say, a Data Access static class (for thread safety) between multiple business logic classes, while not subscribing them to inherit that class/trip over each other in connection pools, and to ultimately avoid allowing a DAL class to promote access at the public level. This has countless backings in design and best practices.

Entity Framework makes good use of this type of access

In case it is useful... I was hitting the "10 $digest() iterations reached. Aborting!" error when using $window.history.back(); with IE9 (works fine in other browsers of course).

I got it to work by using:

setTimeout(function() {
  $window.history.back();
},100);

Disablend ScrollView

ScrollView sw = (ScrollView) findViewById(R.id.scrollView1);
sw.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        return true;
    }
});

Fabrício's answer is spot on; but I wanted to complement his answer with something less technical, which focusses on an analogy to help explain the concept of asynchronicity.

An Analogy...

Yesterday, the work I was doing required some information from a colleague. I rang him up; here's how the conversation went:

Me: Hi Bob, I need to know how we foo'd the bar'd last week. Jim wants a report on it, and you're the only one who knows the details about it.

Bob: Sure thing, but it'll take me around 30 minutes?

Me: That's great Bob. Give me a ring back when you've got the information!

At this point, I hung up the phone. Since I needed information from Bob to complete my report, I left the report and went for a coffee instead, then I caught up on some email. 40 minutes later (Bob is slow), Bob called back and gave me the information I needed. At this point, I resumed my work with my report, as I had all the information I needed.

Imagine if the conversation had gone like this instead;

Me: Hi Bob, I need to know how we foo'd the bar'd last week. Jim want's a report on it, and you're the only one who knows the details about it.

Bob: Sure thing, but it'll take me around 30 minutes?

Me: That's great Bob. I'll wait.

And I sat there and waited. And waited. And waited. For 40 minutes. Doing nothing but waiting. Eventually, Bob gave me the information, we hung up, and I completed my report. But I'd lost 40 minutes of productivity.

This is asynchronous vs. synchronous behavior

This is exactly what is happening in all the examples in our question. Loading an image, loading a file off disk, and requesting a page via AJAX are all slow operations (in the context of modern computing).

Rather than waiting for these slow operations to complete, JavaScript lets you register a callback function which will be executed when the slow operation has completed. In the meantime, however, JavaScript will continue to execute other code. The fact that JavaScript executes other code whilst waiting for the slow operation to complete makes the behaviorasynchronous. Had JavaScript waited around for the operation to complete before executing any other code, this would have been synchronous behavior.

var outerScopeVar;    
var img = document.createElement('img');

// Here we register the callback function.
img.onload = function() {
    // Code within this function will be executed once the image has loaded.
    outerScopeVar = this.width;
};

// But, while the image is loading, JavaScript continues executing, and
// processes the following lines of JavaScript.
img.src = 'lolcat.png';
alert(outerScopeVar);

In the code above, we're asking JavaScript to load lolcat.png, which is a sloooow operation. The callback function will be executed once this slow operation has done, but in the meantime, JavaScript will keep processing the next lines of code; i.e. alert(outerScopeVar).

This is why we see the alert showing undefined; since the alert() is processed immediately, rather than after the image has been loaded.

In order to fix our code, all we have to do is move the alert(outerScopeVar) code into the callback function. As a consequence of this, we no longer need the outerScopeVar variable declared as a global variable.

var img = document.createElement('img');

img.onload = function() {
    var localScopeVar = this.width;
    alert(localScopeVar);
};

img.src = 'lolcat.png';

You'll always see a callback is specified as a function, because that's the only* way in JavaScript to define some code, but not execute it until later.

Therefore, in all of our examples, the function() { /* Do something */ } is the callback; to fix all the examples, all we have to do is move the code which needs the response of the operation into there!

^{* Technically you can use eval() as well, but eval() is evil for this purpose}

How do I keep my caller waiting?

You might currently have some code similar to this;

function getWidthOfImage(src) {
    var outerScopeVar;

    var img = document.createElement('img');
    img.onload = function() {
        outerScopeVar = this.width;
    };
    img.src = src;
    return outerScopeVar;
}

var width = getWidthOfImage('lolcat.png');
alert(width);

However, we now know that the return outerScopeVar happens immediately; before the onload callback function has updated the variable. This leads to getWidthOfImage() returning undefined, and undefined being alerted.

To fix this, we need to allow the function calling getWidthOfImage() to register a callback, then move the alert'ing of the width to be within that callback;

function getWidthOfImage(src, cb) {     
    var img = document.createElement('img');
    img.onload = function() {
        cb(this.width);
    };
    img.src = src;
}

getWidthOfImage('lolcat.png', function (width) {
    alert(width);
});

... as before, note that we've been able to remove the global variables (in this case width).

Now there's no need to side load any packages of execute any scripts to get the Play Store on the emulator. Starting from Android Studio 2.4 now you can create an AVD that has Play Store pre-installed on it. Currently it is supported only on the AVDs running Android 7.0 (API 24) system images.

Official Source

Note: Compatible devices are denoted by the new Play Store column.

In addition to above points, it would be good to know that:

1. A task is by default a background task. You cannot have a foreground task. On the other hand a thread can be background or foreground (Use IsBackground property to change the behavior).
2. Tasks created in thread pool recycle the threads which helps save resources. So in most cases tasks should be your default choice.
3. If the operations are quick, it is much better to use a task instead of thread. For long running operations, tasks do not provide much advantages over threads.

There's no primitive for this in C. I'd probably malloc (or perhaps alloca) a long enough buffer and loop over the input. I've also seen it done with a dynamic string library with semantics (but not syntax!) similar to C++'s ostringstream, which is a plausibly more generic solution but it may not be worth the extra complexity just for a single case.

Performance-wise bash outperforms python in the process startup time.

Here are some measurements from my core i7 laptop running Linux Mint:

Starting process                       Startup time

empty /bin/sh script                   1.7 ms
empty /bin/bash script                 2.8 ms
empty python script                    11.1 ms
python script with a few libs*         110 ms

*Python loaded libs are: os, os.path, json, time, requests, threading, subprocess

This shows a huge difference however bash execution time degrades quickly if it has to do anything sensible since it usually must call external processes.

If you care about performance use bash only for:

• really simple and frequently called scripts
• scripts that mainly call other processes
• when you need minimal friction between manual administrative actions and scripting - fast check a few commands and place them in the file.sh

                tblDynamic.Columns.Add(new DataColumn("TypeName", typeof(string)));

//fill column data against ds.Tables[13]


                for (int i = 0; i < tblDynamic.Rows.Count; i++)
                {

                    if (tblDynamic.Rows[i]["Type"].ToString()=="A")
                    {
                        tblDynamic.Rows[i]["TypeName"] = "Apple";
                    }
                    if (tblDynamic.Rows[i]["Type"].ToString() == "B")
                    {
                        tblDynamic.Rows[i]["TypeName"] = "Ball";
                    }
                    if (tblDynamic.Rows[i]["Type"].ToString() == "C")

                        tblDynamic.Rows[i]["TypeName"] = "Cat";
                    }

We can use

Model::whereNotNull('sent_at');

Or

Model::whereRaw('sent_at is not null');

A very simple way to read an external script into an sqlite database in python is using executescript():

import sqlite3

conn = sqlite3.connect('csc455_HW3.db')

with open('ZooDatabase.sql', 'r') as sql_file:
    conn.executescript(sql_file.read())

conn.close()

Very simple by using the string format

on .ToString("") :

• if you use "hh" ->> The hour, using a 12-hour clock from 01 to 12.

• if you use "HH" ->> The hour, using a 24-hour clock from 00 to 23.

• if you add "tt" ->> The Am/Pm designator.

exemple converting from 23:12 to 11:12 Pm :

DateTime d = new DateTime(1, 1, 1, 23, 12, 0);
var res = d.ToString("hh:mm tt");   // this show  11:12 Pm
var res2 = d.ToString("HH:mm");  // this show  23:12

Console.WriteLine(res);
Console.WriteLine(res2);

Console.Read();

wait a second that is not all you need to care about something else is the system Culture because the same code executed on windows with other langage especialy with difrent culture langage will generate difrent result with the same code

exemple of windows set to Arabic langage culture will show like that :

// 23:12 ?

? means Evening (first leter of ????) .

in another system culture depend on what is set on the windows regional and language option, it will show // 23:12 du.

you can change between different format on windows control panel under windows regional and language -> current format (combobox) and change... apply it do a rebuild (execute) of your app and watch what iam talking about.

so who can I force showing Am and Pm Words in English event if the culture of the >current system isn't set to English ?

easy just by adding two lines : ->

the first step add using System.Globalization; on top of your code

and modifing the Previous code to be like this :

DateTime d = new DateTime(1, 1, 1, 23, 12, 0);
var res = d.ToString("HH:mm tt", CultureInfo.InvariantCulture); // this show  11:12 Pm

InvariantCulture => using default English Format.

another question I want to have the pm to be in Arabic or specific language, even if I use windows set to English (or other language) regional format?

Soution for Arabic Exemple :

DateTime d = new DateTime(1, 1, 1, 23, 12, 0);
var res = d.ToString("HH:mm tt", CultureInfo.CreateSpecificCulture("ar-AE")); 

this will show // 23:12 ?

event if my system is set to an English region format. you can change "ar-AE" if you want to another language format. there is a list of each language and its format.

exemples :

ar          ar-SA       Arabic
ar-BH       ar-BH       Arabic (Bahrain)
ar-DZ       ar-DZ       Arabic (Algeria)
ar-EG       ar-EG       Arabic (Egypt)

big list...

make me know if you have another question .

I generally like to use my own extension for that:

string data = "THExxQUICKxxBROWNxxFOX";
var dataspt = data.Split("xx");
//>THE  QUICK  BROWN  FOX 


//the extension class must be declared as static
public static class StringExtension
{   
    public static string[] Split(this string str, string splitter)
    {
        return str.Split(new[] { splitter }, StringSplitOptions.None);
    }
}

This will however lead to an Exception, if Microsoft decides to include this method-overload in later versions. It is also the likely reason why Microsoft has not included this method in the meantime: At least one company I worked for, used such an extension in all their C# projects.

It may also be possible to conditionally define the method at runtime if it doesn't exist.

After hours of trial and error, I've found a very easy way to put contents into scrollviews that are 'offscreen'. Tested with XCode 5 & iOS 7. You can do this almost entirely in Storyboard, using 2 small tricks/workarounds :

1. Drag a viewcontroller onto your storyboard.
2. Drag a scrollView on this viewController, for the demo you can leave its size default, covering the entire screen.
3. Now comes trick 1 : before adding any element to the scrollView, drag in a regular 'view' (This view will be made larger than the screen, and will contain all the sub elements like buttons, labels, ...let's call it the 'enclosing view').
4. Let this enclosing view's Y size in the size inspector to for example 800.
5. Drop in a label onto the enclosing view, somewhere at Y position 200, name it 'label 1'.
6. Trick 2 : make sure the enclosing view is selected (not the scrollView !), and set its Y position to for example -250, so you can add an item that is 'outside' the screen
7. Drop in a label, somewhere at the bottom of the screen, name it 'label 2'. This label is actually 'off screen'.
8. Reset the Y position of the enclosing view to 0, you'll no longer see label 2, as it was positioned off screen.

So far for the storyboard work, now you need to add a single line of code to the viewController's 'viewDidLoad' method to set the scrollViews contents so it contains the entire 'enclosing view'. I didn't find a way to do this in Storyboard:

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.scrollView.contentSize = CGSizeMake(320, 800);
}

You can try doing this by adding a contentSize keyPath as a size to the scrollView in the Identity Inspector and setting it to (320, 1000).

I think Apple should make this easier in storyboard, in a TableViewController you can just scroll offscreen in Storyboard (just add 20 cells, and you'll see you can simply scroll), this should be possible with a ScrollViewController too.

DELETE FROM on_search 
WHERE search_date < UNIX_TIMESTAMP(DATE_SUB(NOW(), INTERVAL 180 DAY))

You can also run your app like any other console applications but only after the publish.

Let's suppose you have the simple console app named MyTestConsoleApp. Open the package manager console and run the following command:

dotnet publish -c Debug -r win10-x64 

-c flag mean that you want to use the debug configuration (in other case you should use Release value) - r flag mean that your application will be runned on Windows platform with x64 architecture.

When the publish procedure will be finished your will see the *.exe file located in your bin/Debug/publish directory.

Now you can call it via command line tools. So open the CMD window (or terminal) move to the directory where your *.exe file is located and write the next command:

>> MyTestConsoleApp.exe argument-list

For example:

>> MyTestConsoleApp.exe --input some_text -r true

Disabling user-scalable (namely, the ability to double tap to zoom) allows the browser to reduce the click delay. In touch-enable browsers, when the user expects the double tap to zoom, the browser generally waits 300ms before firing the click event, waiting to see if the user will double tap. Disabling user-scalable allows for the Chrome browser to fire the click event immediately, allowing for a better user experience.

I don't know if the solution below is more or less efficient than jspcal's answer, but I'm pretty sure it requires less object creation than Jamie's and George's.

string s = "THIS IS MY TEXT RIGHT NOW";
StringBuilder sb = new StringBuilder(s.Length);
bool capitalize = true;
foreach (char c in s) {
    sb.Append(capitalize ? Char.ToUpper(c) : Char.ToLower(c));
    capitalize = !Char.IsLetter(c);
}
return sb.ToString();

This linq query Should work for you. It will get all the posts that have post meta.

var query = database.Posts.Join(database.Post_Metas,
                                post => post.postId, // Primary Key
                                meta => meat.postId, // Foreign Key
                                (post, meta) => new { Post = post, Meta = meta });

Equivalent SQL Query

Select * FROM Posts P
INNER JOIN Post_Metas pm ON pm.postId=p.postId

The accepted answer doesn't work for UILocalNotification. For some reason, %%%% (4 percent signs) or the unicode character '\uFF05' only work for this.

So to recap, when formatting your string you may use %%. However, if your string is part of a UILocalNotification, use %%%% or \uFF05.

Couldn't find any definitive reference, but I see that the example code for os.walk uses os.path but only imports os

In my case, I was able to use a simple insert statement to bulk insert many rows into TABLE_A using just one column from TABLE_B and getting the other data elsewhere (sequence and a hardcoded value) :

INSERT INTO table_a (
    id,
    column_a,
    column_b
)
    SELECT
        table_a_seq.NEXTVAL,
        b.name,
        123
    FROM
        table_b b;

Result:

ID: NAME: CODE:
1, JOHN, 123
2, SAM, 123
3, JESS, 123

etc

In angular, They separate it into 2 kind of url.

1. URL pattern /heroes/:limit. Example: /heroes/20

   • You can get raw value by using route.snapshot.paramMap.get.
   • Subscribe from route.paramMap to get params

2. URL pattern /heroes. Example: /heroes?limit=20

   • You can get raw value by using route.snapshot.queryParamMap

Here's a nice answer from the FAQ on the scipy.org website:

What advantages do NumPy arrays offer over (nested) Python lists?

Python’s lists are efficient general-purpose containers. They support (fairly) efficient insertion, deletion, appending, and concatenation, and Python’s list comprehensions make them easy to construct and manipulate. However, they have certain limitations: they don’t support “vectorized” operations like elementwise addition and multiplication, and the fact that they can contain objects of differing types mean that Python must store type information for every element, and must execute type dispatching code when operating on each element. This also means that very few list operations can be carried out by efficient C loops – each iteration would require type checks and other Python API bookkeeping.

 public enum Operator
    {
        PLUS, MINUS, MULTIPLY, DIVIDE
    }

    public class Calc
    {
        public void Calculate(int left, int right, Operator op)
        {

            switch (op)
            {
                case Operator.DIVIDE:
                    //Divide
                    break;
                case Operator.MINUS:
                    //Minus
                    break;
                case Operator.MULTIPLY:
                    //...
                    break;
                case Operator.PLUS:
                    //;;
                    break;
                default:
                    throw new InvalidOperationException("Couldn't process operation: " + op);
            }
        }
    }

In case of getting "Could not locate device support files" after your device iOS version has been updated and your Xcode is still old version, just copy old SDK under new name and restart Xcode. Open your terminal and do following:

$ cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/
$ cp -rpv  10.3.1\ \(14E8301\)/ 11.2.1

Restart Xcode and it will most probably work.

I can't get to your google docs file at the moment but there are some issues with your code that I will try to address while answering

            'If the columns don't match, or the x value is not a time
            'then we'll move to the next dep time (x)
        Next x
    Next t

EDIT

I changed you worksheet to play with (see above for the new Sub). This probably does not suite your needs directly, but hopefully it will demonstrate the conept behind what I think you want to do. Please keep in mind that this code does not follow all the coding best preactices I would recommend (e.g. validating the time is actually a TIME and not some random other data type).

I had this problem today and it didn't have anything to do with any of the other answers. Here's what I did and how I fixed it:

A repository of mine recently moved, but I had a local copy. I branched off of my local "master" branch and made some changes--and then I remembered that the repository had moved. I used git remote set-url origin https://<my_new_repository_url> to set the new URL but when I pushed it would just say "Everything up to date" instead of pushing my new branch to master.

I ended up solving it by rebasing onto origin/master and then pushing with explicit branch names, like this:

$ git rebase <my_branch> origin/master
$ git push origin <my_branch>

I hope this helps anyone who had my same problem!

If you are using Eclipse and this problem appeared out of nowhere after everything worked fine beforehand, try going to Project - Clean - Clean.

It sounds like possibly one or more of the columns being selected with:

   e.eval, e.batch_no, e.crsnum, e.lect_code, e.prof_course

has AllowDBNull set to False in your Dataset defintion.

Have you tried to remove the proxy username and password? A similar poster encountered that issue:

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-jar-plugin:2.3.2 or one of its dependencies could not be resolved

Failing that I found the following worked:

1. Delete project in Eclipse (but do not delete the contents on disk)
2. Delete all files in your Maven repository
3. Re-download all Maven dependencies:

mvn dependency:resolve

4. Start up Eclipse
5. Ensure that Eclipse is configured to use your external Maven installation (Window->Preferences->Maven->Installations)
6. Re-import the existing project(s) into Eclipse
7. Ensure that there are no Maven Eclipse plugin errors on the final screen of the project import

Using the previous method with more than 1 slide at time was giving me the wrong total so I've used the "dotsClass", like this (on v1.7.1):

// JS

var slidesPerPage = 6

$(".slick").on("init", function(event, slick){
   maxPages = Math.ceil(slick.slideCount/slidesPerPage);
   $(this).find('.slider-paging-number li').append('/ '+maxPages);
});

$(".slick").slick({
   slidesToShow: slidesPerPage,
   slidesToScroll: slidesPerPage,
   arrows: false,
   autoplay: true,
   dots: true,
   infinite: true,
   dotsClass: 'slider-paging-number'
});

// CSS

ul.slider-paging-number {
    list-style: none;
    li {
        display: none;
        &.slick-active {
            display: inline-block;
        }
        button {

In kotlin

fun determineScreenDensityCode(): String {
      return when (resources.displayMetrics.densityDpi) {
         DisplayMetrics.DENSITY_LOW -> "ldpi"
         DisplayMetrics.DENSITY_MEDIUM -> "mdpi"
         DisplayMetrics.DENSITY_HIGH -> "hdpi"
         DisplayMetrics.DENSITY_XHIGH, DisplayMetrics.DENSITY_280 -> "xhdpi"
         DisplayMetrics.DENSITY_XXHIGH, DisplayMetrics.DENSITY_360, DisplayMetrics.DENSITY_400, DisplayMetrics.DENSITY_420 -> "xxhdpi"
         DisplayMetrics.DENSITY_XXXHIGH, DisplayMetrics.DENSITY_560 -> "xxxhdpi"
         else -> "Unknown code ${resources.displayMetrics.densityDpi}"
     }
}

You can call by println("density: ${determineScreenDensityCode()}") and the output will be System.out: density: xxxhdpi

Just to complete the answer, If you are using the LINQ syntax, you can just wrap it since it returns an IEnumerable:

(from int x in intList
 where x > 5
 select x * 2).FirstOrDefault()

you could use datetime library to get UTC time even local time.

import datetime

utc_time = datetime.datetime.utcnow() 
print(utc_time.strftime('%Y%m%d %H%M%S'))

            setattr(self, field, value)
        self.save(update_fields=kwargs.keys())

The self._state.adding check checks to see if the model is saved to the database, and if not, raises an error.

(Note: This update method is for when you want to update a model and you know the instance is already saved to the database, directly answering the original question. The built-in update_or_create method featured in Platinum Azure's answer already covers the other use-case.)

You would use it like this (after mixing this into your user model):

user = request.user
user.update(favorite_food="ramen")

Besides having a nicer API, another advantage to this approach is that it calls the pre_save and post_save hooks, while still avoiding atomicity issues if another process is updating the same model.

The case class construct in Scala can also be seen as a convenience to remove some boilerplate.

When constructing a case class Scala gives you the following.

• It creates a class as well as its companion object
• Its companion object implements the apply method that you are able to use as a factory method. You get the syntactic sugar advantage of not having to use the new keyword.

  ---

Because the class is immutable you get accessors, which are just the variables (or properties) of the class but no mutators (so no ability to change the variables). The constructor parameters are automatically available to you as public read only fields. Much nicer to use than Java bean construct.

• You also get hashCode, equals, and toString methods by default and the equals method compares an object structurally. A copy method is generated to be able to clone an object (with some fields having new values provided to the method).

The biggest advantage as has been mentioned previously is the fact that you can pattern match on case classes. The reason for this is because you get the unapply method which lets you deconstruct a case class to extract its fields.

In essence what you are getting from Scala when creating a case class (or a case object if your class takes no arguments) is a singleton object which serves the purpose as a factory and as an extractor .

Try this sample. It works for me.

public static void main(String[] args) {  

    Logger logger = Logger.getLogger("MyLog");  
    FileHandler fh;  

    try {  

        // This block configure the logger with handler and formatter  
        fh = new FileHandler("C:/temp/test/MyLogFile.log");  
        logger.addHandler(fh);
        SimpleFormatter formatter = new SimpleFormatter();  
        fh.setFormatter(formatter);  

        // the following statement is used to log any messages  
        logger.info("My first log");  

    } catch (SecurityException e) {  
        e.printStackTrace();  
    } catch (IOException e) {  
        e.printStackTrace();  
    }  

    logger.info("Hi How r u?");  

}

Produces the output at MyLogFile.log

Apr 2, 2013 9:57:08 AM testing.MyLogger main  
INFO: My first log  
Apr 2, 2013 9:57:08 AM testing.MyLogger main  
INFO: Hi How r u?

Edit:

To remove the console handler, use

logger.setUseParentHandlers(false);

since the ConsoleHandler is registered with the parent logger from which all the loggers derive.

The chosen answer works but will fail if the popover is initialized with the body as the container.

$('a').popover({ container: 'body' });

A solution based on the chosen answer is the following code that needs to be placed before using the popover.

var originalLeave = $.fn.popover.Constructor.prototype.leave;
$.fn.popover.Constructor.prototype.leave = function(obj) {
    var self = obj instanceof this.constructor ? obj : $(obj.currentTarget)[this.type](this.getDelegateOptions()).data('bs.' + this.type);
    originalLeave.call(this, obj);

    if (obj.currentTarget) {
        self.$tip.one('mouseenter', function() {
            clearTimeout(self.timeout);
            self.$tip.one('mouseleave', function() {
                $.fn.popover.Constructor.prototype.leave.call(self, self);
            });
        })
    }
};

The change is minimal using self.$tip instead of traversing the DOM expecting the popover to be always a siblings of the element.

Adding on to Nick Craver's answer and also considering the point raised by rossisdead, if scenario exists like one has to append to an empty table, or before a certain row, I have done like this:

var arr = []; //array
if (your condition) {
  arr.push(row.id); //push row's id for eg: to the array
  idx = arr.sort().indexOf(row.id);

  if (idx === 0) {   
    if (arr.length === 1) {  //if array size is only 1 (currently pushed item)
        $("#tableID").append(row);
    }
    else {       //if array size more than 1, but index still 0, meaning inserted row must be the first row
       $("#tableID tr").eq(idx + 1).before(row);
    }   
  }          
  else {     //if index is greater than 0, meaning inserted row to be after specified index row
      $("#tableID tr").eq(idx).after(row);
  }    
}

Hope it helps someone.

You need to enclose the date time value in quotes:

DECLARE @Test AS DATETIME 

SET @Test = '2011-02-15'

PRINT @Test

@paul_g's method was pretty close for me, my steps on a Mac osx10.9 Retina:

• Install macports
• Install rvm (stable with ruby add --insecure flag for SSL related issues) $\curl -sSL --insecure https://get.rvm.io | bash -s stable --ruby
• Restart Terminal / Resource your profile
• Run rvm requirements --with-gcc=clang You won't have to update Ruby because you downloaded the last stable version
• And last step to run gem install compass --pre

The error also happens when trying to use the

The MOST IMPORTANT THING I didn't understand for quite awhile is that the request MUST contain "callback=JSON_CALLBACK", because AngularJS modifies the request url, substituting a unique identifier for "JSON_CALLBACK". The server response must use the value of the 'callback' parameter instead of hard coding "JSON_CALLBACK":

JSON_CALLBACK(json_response);  // wrong!

Since I was writing my own PHP server script, I thought I knew what function name it wanted and didn't need to pass "callback=JSON_CALLBACK" in the request. Big mistake!

AngularJS replaces "JSON_CALLBACK" in the request with a unique function name (like "callback=angular.callbacks._0"), and the server response must return that value:

angular.callbacks._0(json_response);

On Linux, you can use

date -d "-1 days" +"%a %d/%m/%Y"

This doesn't work and it shouldn't because it would be a giant security hole.

Have a look at the new File System API. It allows you to request access to a virtual, sandboxed filesystem governed by the browser. You will have to request your user to "upload" their file into the sandboxed filesystem once, but afterwards you can work with it very elegantly.

While this definitely is the future, it is still highly experimental and only works in Google Chrome as far as CanIUse knows.

— :: — :: \u2014

When representing the m-dash in a JavaScript text string for output to HTML, note that it will be represented by its unicode value. There are cases when ampersand characters ('&') will not be resolved—notably certain contexts within JSX. In this case, neither — nor — will work. Instead you need to use the Unicode escape sequence: \u2014.

For example, when implementing a render() method to output text from a JavaScript variable:

render() {
   let text='JSX transcoders will preserve the & character—to ' 
            + 'protect from possible script hacking and cross-site hacks.'
   return (
     <div>{text}</div>
   )
}

This will output:

<div>JSX transcoders will preserve the & character&mdash;to protect from possible script hacking and cross-site hacks.</div>

Instead of the &– prefixed representation, you should use \u2014:

let text='JSX transcoders will preserve the & character\u2014to …'

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

In that case, try adding a listener

yourFunction () {
  // some ocde

}

Good luck!

When using checkboxes as an array:

<input type="checkbox" name="food[]" value="Orange">
<input type="checkbox" name="food[]" value="Apple">

You should use in_array():

if(in_array('Orange', $_POST['food'])){
  echo 'Orange was checked!';
}

Remember to check the array is set first, such as:

if(isset($_POST['food']) && in_array(...

You can also add a .pth file containing the desired directory in either your c:\PythonX.X folder, or your \site-packages folder, which tends to be my preferred method when I'm developing a Python package.

Spring framework itself handles json conversion when controller is annotated properly.

For eg:

   @PutMapping(produces = {"application/json"})
        @ResponseBody
        public UpdateResponse someMethod(){ //do something
return UpdateResponseInstance;
}

Here spring internally converts the UpdateResponse object to corresponding json string and returns it. In order to do it spring internally uses Jackson library.

If you require a json representation of a model object anywhere apart from controller then you can use objectMapper provided by jackson. Model should be properly annotated for this to work.

Eg:

ObjectMapper mapper = new ObjectMapper();
SomeModelClass someModelObject = someModelRepository.findById(idValue).get();
mapper.writeValueAsString(someModelObject);

Take care not to include

#include <string.h> 

but only

#include <string>

It took me 1 hour to find this in my code.

Hope this can help

This answer expounds on John Black's helpful answer, so I will repeat some of his answer content in my answer.

The easiest way to resize a marker seems to be leaving argument 2, 3, and 4 null and scaling the size in argument 5.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|FFFF00",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(42, 68)
);  

As an aside, this answer to a similar question asserts that defining marker size in the 2nd argument is better than scaling in the 5th argument. I don't know if this is true.

Leaving arguments 2-4 null works great for the default google pin image, but you must set an anchor explicitly for the default google pin shadow image, or it will look like this:

The bottom center of the pin image happens to be collocated with the tip of the pin when you view the graphic on the map. This is important, because the marker's position property (marker's LatLng position on the map) will automatically be collocated with the visual tip of the pin when you leave the anchor (4th argument) null. In other words, leaving the anchor null ensures the tip points where it is supposed to point.

However, the tip of the shadow is not located at the bottom center. So you need to set the 4th argument explicitly to offset the tip of the pin shadow so the shadow's tip will be colocated with the pin image's tip.

By experimenting I found the tip of the shadow should be set like this: x is 1/3 of size and y is 100% of size.

var pinShadow = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_shadow",
    null,
    null,
    /* Offset x axis 33% of overall size, Offset y axis 100% of overall size */
    new google.maps.Point(40, 110), 
    new google.maps.Size(120, 110)); 

to give this:

Definitively:

template<class T>
T ror(T x, unsigned int moves)
{
  return (x >> moves) | (x << sizeof(T)*8 - moves);
}

I haven't attempted this myself, so its just an idea... but have you tried using media queries with CSS to see when the height of the window changes and then change the design for that? I would imagine that Safari mobile isn't recognizing the keyboard as part of the window so that would hopefully work.

Example:

@media all and (height: 200px){
    #content {height: 100px; overflow: hidden;}
}

Just call moment as a function without any arguments:

moment()

For timezone information with moment, look at the moment-timezone package: http://momentjs.com/timezone/

boolean containsWhitespace = false;
for (int i = 0; i < text.length() && !containsWhitespace; i++) {
    if (Character.isWhitespace(text.charAt(i)) {
        containsWhitespace = true;
    }
}
return containsWhitespace;

or, using Guava,

boolean containsWhitespace = CharMatcher.WHITESPACE.matchesAnyOf(text);

This is an old post, but here is my solution :

Thread.currentThread().dumpStack();

More info and more methods there : http://javarevisited.blogspot.fr/2013/04/how-to-get-current-stack-trace-in-java-thread.html

You should use the os.Stat() and os.IsNotExist() functions as in the following example:

// Exists reports whether the named file or directory exists.
func Exists(name string) bool {
    if _, err := os.Stat(name); err != nil {
        if os.IsNotExist(err) {
            return false
        }
    }
    return true
}

The example is extracted from here.

$.extend($.expr[':'], {
        unchecked: function (obj) {
            return ((obj.type == 'checkbox' || obj.type == 'radio') && !$(obj).is(':checked'));
        }
    });

$("input:checked")
$("input:unchecked")

Convert an iterable to a list may have a cost. Instead, to get the the first item, you can use:

next(iter(keys))

Or, if you want to iterate over all items, you can use:

items = iter(keys)
while True:
    try:
        item = next(items)
    except StopIteration as e:
        pass # finish

All the answers here suggest to use ipairs but beware, it does not work all the time.

t = {[2] = 44, [4]=77, [6]=88}

--This for loop prints the table
for key,value in next,t,nil do 
  print(key,value) 
end

--This one does not print the table
for key,value in ipairs(t) do 
  print(key,value) 
end

This seems to be due to a problem in the UITableViewController subclass template. It comes with a version of the prepareForSegue method that would require you to unwrap the segue.

Replace your current prepareForSegue function with:

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    if (segue.identifier == "Load View") {
        // pass data to next view
    }
}

This version implicitly unwraps the parameters, so you should be fine.

This one works for me. You can see this code on AccountController -> Register

var user = new JobUser { UserName = model.Email, Email = model.Email };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
    //add this to add role to user
     await UserManager.AddToRoleAsync(user.Id, "Name of your role");
}

but the role name must exist in your AspNetRoles table.

1. Download the latest JDBC Driver (i.e. sqljdbc4.0) from Microsoft's web site

2. Write the program as follows:

   import java.sql.*;
   class testmssql
   {
       public static void main(String args[]) throws Exception
       {
           Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
           Connection      con=DriverManager.getConnection("jdbc:sqlserver://localhost:1433;
                   databaseName=chapter16","sa","123");//repalce your databse name and user name
               Statement st=con.createStatement();
           ResultSet rs=st.executeQuery("Select * from login");//replace your table name
           while(rs.next())
           {
               String s1=rs.getString(1);
               String s2=rs.getString(2);
               System.out.println("UserID:"+s1+"Password:"+s2);
           }
           con.close();
       } 
   }
   

3. Compile the program and set the jar classpath viz: set classpath=C:\jdbc\sqljdbc4.jar;.; If you have saved your jar file in C:\jdbc after downloading and extracting.

4. Run the program and make sure your TCP/IP service is enabled. If not enabled, then follow these steps:
   1. Go to Start -> All Programs -> Microsoft SQL Server 2008 -> Configuration tools -> SQL Server Configuration Manager
   2. Expand Sql Server Network Configuration: choose your MS SQL Server Instance viz. MSQSLSERVER and enable TCP/IP.
   3. Restart your MS SQL Server Instance. This can be done also from the right click menu of Microsoft SQL Server Management Studio at the root level of your MS SQL server instance

You can make master point at 1258f0d0aae this way:

git checkout master
git reset --hard 1258f0d0aae

But you have to be careful about doing this. It may well rewrite the history of that branch. That would create problems if you have published it and other people are working on the branch.

Also, the git reset --hard command will throw away any uncommitted changes (i.e. those just in your working tree or the index).

You can also force an update to a branch with:

git branch -f master 1258f0d0aae

... but git won't let you do that if you're on master at the time.

Like most form controls in HTML, the results of applying CSS to <select> and <option> elements vary a lot between browsers. Chrome, as you've found, won't let you apply and font styles to an <option> element directly --- if you do Inspect Element on it, you'll see the font-size: 14px declaration is crossed through as if it's been overridden by the cascade, but it's actually because Chrome is ignoring it.

However, Chrome will let you apply font styles to the <optgroup> element, so to achieve the result you want you can wrap all the <option>s in an <optgroup> and then apply your font styles to a .styled-select optgroup selector. If you want the optgroup sans-label, you may have to do some clever CSS with positioning or something to hide the white area at the top where the label would be shown, but that should be possible.

              select new Fruit {Name=f.Name, SeedCount=f.SeedCount};
}

Just a small addition to Jeff Bowman's excellent answer, as I found this question when searching for a solution to one of my own problems:

If a call to a method matches more than one mock's when trained calls, the order of the when calls is important, and should be from the most wider to the most specific. Starting from one of Jeff's examples:

when(foo.quux(anyInt(), anyInt())).thenReturn(true);
when(foo.quux(anyInt(), eq(5))).thenReturn(false);

is the order that ensures the (probably) desired result:

foo.quux(3 /*any int*/, 8 /*any other int than 5*/) //returns true
foo.quux(2 /*any int*/, 5) //returns false

If you inverse the when calls then the result would always be true.

Just FYI, Geocoder is asynchronous so the accepted answer while logical doesn't really work in this instance. I would prefer to have an outside object that acts as your updater.

var updater = {};

function geoCodeCity(goocoord) { 
    var geocoder = new google.maps.Geocoder();
    geocoder.geocode({
        'latLng': goocoord
    }, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            updater.currentLocation = results[1].formatted_address;
        } else {
            if (status == "ERROR") { 
                    console.log(status);
                }
        }
    });
};

• if you are not getting the above output then please make sure the following.

  • I used the default host (localhost) and port (8080) on the above link. please alter the host and port if it is different in your end.
  • The default core name should be collection / collection1. I used collection1 in the above link. please change it too if your core name is different.

If you want the latest file in the directory and you are using only the LastWriteTime to determine the latest file, you can do something like below:

gci path | sort LastWriteTime | select -last 1

On the other hand, if you want to only rely on the names that have the dates in them, you should be able to something similar

gci path | select -last 1

Also, if there are directories in the directory, you might want to add a ?{-not $_.PsIsContainer}

You can't, Print Preview is a feature of a browser, and therefore should be protected from being called by JavaScript as it would be a security risk.

I had the same problem and i found the following solution to be very efficient. I hope that it will help you or everyone else who wants to do the same thing.

First of all, i would start with a "with" statement as it ensures the proper open/close of the file.

It should look something like this:

with open("filename.txt", "r+") as f:
    contents = [x.strip() for x in f.readlines()]

If you want to convert those strings (every item in the contents list is a string) in integer or float you can do the following:

contents = [float(contents[i]) for i in range(len(contents))]

Use int instead of float if you want to convert to integer.

It's my first answer in SO, so sorry if it's not in the proper formatting.

IMPORTANT NOTE: You should not concatenate SQL queries unless you trust the user completely. Query concatenation involves risk of SQL Injection being used to take over the world, ...khem, your database.

If you don't want to go into details how to execute query using SqlCommand then you could call the same command line like this:

string userInput = "Brian";
var process = new Process();
var startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = string.Format(@"sqlcmd.exe -S .\PDATA_SQLEXPRESS -U sa -P 2BeChanged! -d PDATA_SQLEXPRESS  
     -s ; -W -w 100 -Q "" SELECT tPatCulIntPatIDPk, tPatSFirstname, tPatSName,
     tPatDBirthday  FROM  [dbo].[TPatientRaw] WHERE tPatSName = '{0}' """, userInput);

process.StartInfo = startInfo;
process.Start();

Just ensure that you escape each double quote " with ""

In my case, I was creating a framework with Cocoapods. The problems was this line:

s.static_framework = true

in my framework.podspec file

After commented this line above all problems to access storyboards or XIBs went out.

From the PostgreSQL wiki.

_{NOTE: Databases to which the user cannot connect are sorted as if they were infinite size.}

SELECT d.datname AS Name,  pg_catalog.pg_get_userbyid(d.datdba) AS Owner,
    CASE WHEN pg_catalog.has_database_privilege(d.datname, 'CONNECT')
        THEN pg_catalog.pg_size_pretty(pg_catalog.pg_database_size(d.datname))
        ELSE 'No Access'
    END AS Size
FROM pg_catalog.pg_database d
    ORDER BY
    CASE WHEN pg_catalog.has_database_privilege(d.datname, 'CONNECT')
        THEN pg_catalog.pg_database_size(d.datname)
        ELSE NULL
    END DESC -- nulls first
    LIMIT 20

The page also has snippets for finding the size of your biggest relations and largest tables.

Try executing this SQL command:

> grant all privileges 
  on YOUR_DATABASE.* 
  to 'asdfsdf'@'localhost' 
  identified by 'your_password';
> flush privileges; 

It seems that you are having issues with connecting to the database and not writing to the folder you’re mentioning.

Also, make sure you have granted FILE to user 'asdfsdf'@'localhost'.

> GRANT FILE ON *.* TO 'asdfsdf'@'localhost';

Get the path of running Apache

$ ps -ef | grep apache
apache   12846 14590  0 Oct20 ?        00:00:00 /usr/sbin/apache2

Append -V argument to the path

$ /usr/sbin/apache2 -V | grep SERVER_CONFIG_FILE
-D SERVER_CONFIG_FILE="/etc/apache2/apache2.conf"

check out Blueprints:

Blueprints is a collection of interfaces, implementations, ouplementations, and test suites for the property graph data model. Blueprints is analogous to the JDBC, but for graph databases. Within the TinkerPop open source software stack, Blueprints serves as the foundational technology for:

Pipes: A lazy, data flow framework

Gremlin: A graph traversal language

Frames: An object-to-graph mapper

Furnace: A graph algorithms package

Rexster: A graph server

It seems clear that $(TESTS) is empty so your 1.4.0 makefile is effectively

all: 

clean:
  rm -f  gtest.a gtest_main.a *.o

Indeed, all has nothing to do. and clean does exactly what it says rm -f gtest.a ...

Header files can contain any valid C code, since they are injected into the compilation unit by the pre-processor prior to compilation.

If a header file contains a function, and is included by multiple .c files, each .c file will get a copy of that function and create a symbol for it. The linker will complain about the duplicate symbols.

It is technically possible to create static functions in a header file for inclusion in multiple .c files. Though this is generally not done because it breaks from the convention that code is found in .c files and declarations are found in .h files.

See the discussions in C/C++: Static function in header file, what does it mean? for more explanation.

Build lists of matched lines - several flavors:

def lines_that_equal(line_to_match, fp):
    return [line for line in fp if line == line_to_match]

def lines_that_contain(string, fp):
    return [line for line in fp if string in line]

def lines_that_start_with(string, fp):
    return [line for line in fp if line.startswith(string)]

def lines_that_end_with(string, fp):
    return [line for line in fp if line.endswith(string)]

Build generator of matched lines (memory efficient):

def generate_lines_that_equal(string, fp):
    for line in fp:
        if line == string:
            yield line

Print all matching lines (find all matches first, then print them):

with open("file.txt", "r") as fp:
    for line in lines_that_equal("my_string", fp):
        print line

Print all matching lines (print them lazily, as we find them)

with open("file.txt", "r") as fp:
    for line in generate_lines_that_equal("my_string", fp):
        print line

Generators (produced by yield) are your friends, especially with large files that don't fit into memory.

I ran across this thread and just wanted to share this post from Brent Ozar as something to consider when using availability groups.

Brent Ozar bug report

If you want to have your code os-unspecific you should use println for each word

System.out.println("I");
System.out.println("am");
System.out.println("a");
System.out.println("boy");

because Windows uses "\r\n" as newline and unixoid systems use just "\n"

println always uses the correct one

Using below query you can remove leading and trailing whitespace in a MySQL.

UPDATE `table_name`
SET `col_name` = TRIM(`col_name`);

This should work:

s=json.dumps(variables)
variables2=json.loads(s)
assert(variables==variables2)

Here is a simple one liner

var segment = (arr, n) => arr.reduce((r,e,i) => i%n ? (r[r.length-1].push(e), r)_x000D_
                                                    : (r.push([e]), r), []),_x000D_
        arr = Array.from({length: 31}).map((_,i) => i+1);_x000D_
console.log(segment(arr,7));

What I do in my Asp Net Core Api applications it is to create a class that extends from ObjectResult and provide many constructors to customize the content and the status code. Then all my Controller actions use one of the costructors as appropiate. You can take a look at my implementation at: https://github.com/melardev/AspNetCoreApiPaginatedCrud

and

https://github.com/melardev/ApiAspCoreEcommerce

here is how the class looks like(go to my repo for full code):

public class StatusCodeAndDtoWrapper : ObjectResult
{



    public StatusCodeAndDtoWrapper(AppResponse dto, int statusCode = 200) : base(dto)
    {
        StatusCode = statusCode;
    }

    private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, string message) : base(dto)
    {
        StatusCode = statusCode;
        if (dto.FullMessages == null)
            dto.FullMessages = new List<string>(1);
        dto.FullMessages.Add(message);
    }

    private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, ICollection<string> messages) : base(dto)
    {
        StatusCode = statusCode;
        dto.FullMessages = messages;
    }
}

Notice the base(dto) you replace dto by your object and you should be good to go.

I was dealing with this issue today, and I knew that I had something encoded as a bytes object that I was trying to serialize as json with json.dump(my_json_object, write_to_file.json). my_json_object in this case was a very large json object that I had created, so I had several dicts, lists, and strings to look at to find what was still in bytes format.

The way I ended up solving it: the write_to_file.json will have everything up to the bytes object that is causing the issue.

In my particular case this was a line obtained through

for line in text:
    json_object['line'] = line.strip()

I solved by first finding this error with the help of the write_to_file.json, then by correcting it to:

for line in text:
    json_object['line'] = line.strip().decode()

Properly parenthesized for clarity, it is

hsb.s = (max != 0) ? (255 * delta / max) : 0;

meaning return either

• 255*delta/max if max != 0
• 0 if max == 0

You cannot add default values for function parameters. But you can do this:

function tester(paramA, paramB){
 if (typeof paramA == "undefined"){
   paramA = defaultValue;
 }
 if (typeof paramB == "undefined"){
   paramB = defaultValue;
 }
}

To select content use Alt + Shift + Up arrow

To select content up to the next wrapping block press this shortcut again

To go back one step press Alt + Shift + Down arrow. This is also a useful shortcut when you need to select content in a complex expression and do not want to miss something.

No need to upvote this. It would have been cool if Benjamin Lindley made his one-liner comment an answer, but since he hasn't, here goes:

std::vector<std::string> argList(argv, argv + argc);

If you don't want to include argv[0] so you don't need to deal with the executable's location, just increment the pointer by one:

std::vector<std::string> argList(argv + 1, argv + argc);

It's the part of the .NET Framework that isn't contained within the Client Profile. See MSDN for more info; specifically:

The .NET Framework is made up of the .NET Framework 4 Client Profile and .NET Framework 4 Extended components that exist separately in Programs and Features.

You have VisualTkinter also known as Visual Python. Development seems not active. You have sourceforge and googlecode sites. Web site is here.

On the other hand, you have PAGE that seems active and works in python 2.7 and py3k

As you indicate on your comment, none of these use the grid geometry. As far as I can say the only GUI builder doing that could probably be Komodo Pro GUI Builder which was discontinued and made open source in ca. 2007. The code was located in the SpecTcl repository.

It seems to install fine on win7 although has not used it yet. This is an screenshot from my PC:

By the way, Rapyd Tk also had plans to implement grid geometry as in its documentation says it is not ready 'yet'. Unfortunately it seems 'nearly' abandoned.

You can also use remove to remove a value by index as well.

n = [1, 3, 5]

n.remove(n[1])

n would then refer to [1, 5]

Using BitArray class and making an extension method as OP suggests:

public static bool GetBit(this byte b, int bitNumber)
{
    System.Collections.BitArray ba = new BitArray(new byte[]{b});
    return ba.Get(bitNumber);
}

All of the following examples use

var str = "Hello, playground"

startIndex and endIndex

• startIndex is the index of the first character
• endIndex is the index after the last character.

Example

// character
str[str.startIndex] // H
str[str.endIndex]   // error: after last character

// range
let range = str.startIndex..<str.endIndex
str[range]  // "Hello, playground"

With Swift 4's one-sided ranges, the range can be simplified to one of the following forms.

let range = str.startIndex...
let range = ..<str.endIndex

I will use the full form in the follow examples for the sake of clarity, but for the sake of readability, you will probably want to use the one-sided ranges in your code.

after

As in: index(after: String.Index)

• after refers to the index of the character directly after the given index.

Examples

// character
let index = str.index(after: str.startIndex)
str[index]  // "e"

// range
let range = str.index(after: str.startIndex)..<str.endIndex
str[range]  // "ello, playground"

before

As in: index(before: String.Index)

• before refers to the index of the character directly before the given index.

Examples

// character
let index = str.index(before: str.endIndex)
str[index]  // d

// range
let range = str.startIndex..<str.index(before: str.endIndex)
str[range]  // Hello, playgroun

offsetBy

As in: index(String.Index, offsetBy: String.IndexDistance)

• The offsetBy value can be positive or negative and starts from the given index. Although it is of the type String.IndexDistance, you can give it an Int.

Examples

// character
let index = str.index(str.startIndex, offsetBy: 7)
str[index]  // p

// range
let start = str.index(str.startIndex, offsetBy: 7)
let end = str.index(str.endIndex, offsetBy: -6)
let range = start..<end
str[range]  // play

limitedBy

As in: index(String.Index, offsetBy: String.IndexDistance, limitedBy: String.Index)

• The limitedBy is useful for making sure that the offset does not cause the index to go out of bounds. It is a bounding index. Since it is possible for the offset to exceed the limit, this method returns an Optional. It returns nil if the index is out of bounds.

Example

// character
if let index = str.index(str.startIndex, offsetBy: 7, limitedBy: str.endIndex) {
    str[index]  // p
}

If the offset had been 77 instead of 7, then the if statement would have been skipped.

Why is String.Index needed?

It would be much easier to use an Int index for Strings. The reason that you have to create a new String.Index for every String is that Characters in Swift are not all the same length under the hood. A single Swift Character might be composed of one, two, or even more Unicode code points. Thus each unique String must calculate the indexes of its Characters.

It is possibly to hide this complexity behind an Int index extension, but I am reluctant to do so. It is good to be reminded of what is actually happening.
