I had the same problem and after hours of looking found the answer.

The error I was getting was a little different: <path> already exists and is not a valid git repo (and added here for SEO value)

The solution is to NOT create the directory that will house the submodule. The directory will be created as part of the git submodule add command.

Also, the argument is expected to be relative to the parent-repo root, not your working directory, so watch out for that.

Solution for the example above:

1. It IS okay to have your parent repo already cloned.
2. Make sure the common_code directory does not exist.
3. cd Repo
4. git submodule add git://url_to_repo projectfolder/common_code/ (Note the required trailing slash.)
5. Sanity restored.

I hope this helps someone, as there is very little information to be found elsewhere about this.

if you want to follow Android 10 practices to write in storage, check here and if you only want the images to be app specific, here for example if you want to store an image just to be used by your app:

viewModelScope.launch(Dispatchers.IO) {
            getApplication<Application>().openFileOutput(filename, Context.MODE_PRIVATE).use {
                bitmap.compress(Bitmap.CompressFormat.PNG, 50, it)
            }
        }

getApplication is a method to give you context for ViewModel and it's part of AndroidViewModel later if you want to read it:

viewModelScope.launch(Dispatchers.IO) {
            val savedBitmap = BitmapFactory.decodeStream(
                getApplication<App>().openFileInput(filename).readBytes().inputStream()
            )
        }

My comprehensive solution to disable/override all console.* functions is here.

Of course, please make sure you are including it after checking necessary context. For example, only including in production release, it's not bombing any other crucial components etc.

Quoting it here:

I understand that this question is a bit old but I'm going to introduce another solution using redux-observable aka. Epic.

Quoting the official documentation:

What is redux-observable?

RxJS 5-based middleware for Redux. Compose and cancel async actions to create side effects and more.

An Epic is the core primitive of redux-observable.

It is a function which takes a stream of actions and returns a stream of actions. Actions in, actions out.

In more or less words, you can create a function that receives actions through a Stream and then return a new stream of actions (using common side effects such as timeouts, delays, intervals, and requests).

Let me post the code and then explain a bit more about it

store.js

import {createStore, applyMiddleware} from 'redux'
import {createEpicMiddleware} from 'redux-observable'
import {Observable} from 'rxjs'
const NEW_NOTIFICATION = 'NEW_NOTIFICATION'
const QUIT_NOTIFICATION = 'QUIT_NOTIFICATION'
const NOTIFICATION_TIMEOUT = 2000

const initialState = ''
const rootReducer = (state = initialState, action) => {
  const {type, message} = action
  console.log(type)
  switch(type) {
    case NEW_NOTIFICATION:
      return message
    break
    case QUIT_NOTIFICATION:
      return initialState
    break
  }

  return state
}

const rootEpic = (action$) => {
  const incoming = action$.ofType(NEW_NOTIFICATION)
  const outgoing = incoming.switchMap((action) => {
    return Observable.of(quitNotification())
      .delay(NOTIFICATION_TIMEOUT)
      //.takeUntil(action$.ofType(NEW_NOTIFICATION))
  });

  return outgoing;
}

export function newNotification(message) {
  return ({type: NEW_NOTIFICATION, message})
}
export function quitNotification(message) {
  return ({type: QUIT_NOTIFICATION, message});
}

export const configureStore = () => createStore(
  rootReducer,
  applyMiddleware(createEpicMiddleware(rootEpic))
)

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import {configureStore} from './store.js'
import {Provider} from 'react-redux'

const store = configureStore()

ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById('root')
);

App.js

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

class App extends Component {

  render() {
    return (
      <div className="App">
        {this.props.notificationExistance ? (<p>{this.props.notificationMessage}</p>) : ''}
        <button onClick={this.props.onNotificationRequest}>Click!</button>
      </div>
    );
  }
}

const mapStateToProps = (state) => {
  return {
    notificationExistance : state.length > 0,
    notificationMessage : state
  }
}

const mapDispatchToProps = (dispatch) => {
  return {
    onNotificationRequest: () => dispatch(newNotification(new Date().toDateString()))
  }
}

export default connect(mapStateToProps, mapDispatchToProps)(App)

The key code to solve this problem is as easy as pie as you can see, the only thing that appears different from the other answers is the function rootEpic.

Point 1. As with sagas, you have to combine the epics in order to get a top level function that receives a stream of actions and returns a stream of actions, so you can use it with the middleware factory createEpicMiddleware. In our case we only need one so we only have our rootEpic so we don't have to combine anything but it's a good to know fact.

Point 2. Our rootEpic which takes care about the side effects logic only takes about 5 lines of code which is awesome! Including the fact that is pretty much declarative!

Point 3. Line by line rootEpic explanation (in comments)

const rootEpic = (action$) => {
  // sets the incoming constant as a stream 
  // of actions with  type NEW_NOTIFICATION
  const incoming = action$.ofType(NEW_NOTIFICATION)
  // Merges the "incoming" stream with the stream resulting for each call
  // This functionality is similar to flatMap (or Promise.all in some way)
  // It creates a new stream with the values of incoming and 
  // the resulting values of the stream generated by the function passed
  // but it stops the merge when incoming gets a new value SO!,
  // in result: no quitNotification action is set in the resulting stream
  // in case there is a new alert
  const outgoing = incoming.switchMap((action) => {
    // creates of observable with the value passed 
    // (a stream with only one node)
    return Observable.of(quitNotification())
      // it waits before sending the nodes 
      // from the Observable.of(...) statement
      .delay(NOTIFICATION_TIMEOUT)
  });
  // we return the resulting stream
  return outgoing;
}

I hope it helps!

Try with:

$foo2 = array_slice($foo, 1);

You can reference those remote tracking branches ~(listed with git branch -r) with the name of their remote.

You need to fetch the remote branch:

git fetch origin aRemoteBranch

If you want to merge one of those remote branches on your local branch:

git checkout master
git merge origin/aRemoteBranch

Note 1: For a large repo with a long history, you will want to add the --depth=1 option when you use git fetch.

Note 2: These commands also work with other remote repos so you can setup an origin and an upstream if you are working on a fork.

Note 3: user3265569 suggests the following alias in the comments:

From aLocalBranch, run git combine remoteBranch
Alias:

combine = !git fetch origin ${1} && git merge origin/${1}

Opposite scenario: If you want to merge one of your local branch on a remote branch (as opposed to a remote branch to a local one, as shown above), you need to create a new local branch on top of said remote branch first:

git checkout -b myBranch origin/aBranch
git merge anotherLocalBranch

The idea here, is to merge "one of your local branch" (here anotherLocalBranch) to a remote branch (origin/aBranch).
For that, you create first "myBranch" as representing that remote branch: that is the git checkout -b myBranch origin/aBranch part.
And then you can merge anotherLocalBranch to it (to myBranch).

I had the same problem but the issue was a different one, I was trying to create a service and pass $scope to it as a parameter.
That's another way to get this error as the documentation of that link says:

Attempting to inject a scope object into anything that's not a controller or a directive, for example a service, will also throw an Unknown provider: $scopeProvider <- $scope error. This might happen if one mistakenly registers a controller as a service, ex.:

angular.module('myModule', [])
       .service('MyController', ['$scope', function($scope) {
        // This controller throws an unknown provider error because
        // a scope object cannot be injected into a service.
}]);

With CSS only? This is sort of possible on text inputs by using user-select:none:

.print {
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;          
}

JSFiddle example.

It's well worth noting that this will not work in browsers which do not support CSS3 or support the user-select property. The readonly property should be ideally given to the input markup you wish to be made readonly, but this does work as a hacky CSS alternative.

With JavaScript:

document.getElementById("myReadonlyInput").setAttribute("readonly", "true");

Edit: The CSS method no longer works in Chrome (29). The -webkit-user-select property now appears to be ignored on input elements.

According to BOL:

Indexed views and indexes on computed columns store results in the database for later reference. The stored results are valid only if all connections referring to the indexed view or indexed computed column can generate the same result set as the connection that created the index.

In order to create a table with a persisted, computed column, the following connection settings must be enabled:

SET ANSI_NULLS ON
SET ANSI_PADDING ON
SET ANSI_WARNINGS ON
SET ARITHABORT ON
SET CONCAT_NULL_YIELDS_NULL ON
SET NUMERIC_ROUNDABORT ON
SET QUOTED_IDENTIFIER ON

These values are set on the database level and can be viewed using:

SELECT 
    is_ansi_nulls_on,
    is_ansi_padding_on,
    is_ansi_warnings_on,
    is_arithabort_on,
    is_concat_null_yields_null_on,
    is_numeric_roundabort_on,
    is_quoted_identifier_on
FROM sys.databases

However, the SET options can also be set by the client application connecting to SQL Server.

A perfect example is SQL Server Management Studio which has the default values for SET ANSI_NULLS and SET QUOTED_IDENTIFIER both to ON. This is one of the reasons why I could not initially duplicate the error you posted.

Anyway, to duplicate the error, try this (this will override the SSMS default settings):

SET ANSI_NULLS ON
SET ANSI_PADDING OFF
SET ANSI_WARNINGS OFF
SET ARITHABORT OFF
SET CONCAT_NULL_YIELDS_NULL ON 
SET NUMERIC_ROUNDABORT OFF
SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE T1 (
    ID INT NOT NULL,
    TypeVal AS ((1)) PERSISTED NOT NULL
) 

You can fix the test case above by using:

SET ANSI_PADDING ON
SET ANSI_WARNINGS ON

I would recommend tweaking these two settings in your script before the creation of the table and related indexes.

Use the in keyword.

if 'apples' in d:
    if d['apples'] == 20:
        print('20 apples')
    else:
        print('Not 20 apples')

If you want to get the value only if the key exists (and avoid an exception trying to get it if it doesn't), then you can use the get function from a dictionary, passing an optional default value as the second argument (if you don't pass it it returns None instead):

if d.get('apples', 0) == 20:
    print('20 apples.')
else:
    print('Not 20 apples.')

Answered code-snippet posted by Leandros seems bit old. I have fixed and made it compilable in Swift 5.

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    self.window = UIWindow(frame: UIScreen.main.bounds)
    let controller = UIViewController()
    let view = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 568))
    view.backgroundColor = UIColor.red
    controller.view = view

    let label = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 21))
    label.center = CGPoint(x: 160, y: 284)
    label.textAlignment = NSTextAlignment.center
    label.text = "I'am a test label"
    controller.view.addSubview(label)

    self.window!.rootViewController = controller
    self.window!.makeKeyAndVisible()
    return true
}

From MYSQL I solved the problem like this:

You're checking i's UniqueID while i is actually an integer. You should do something like that, if you want to stay with a for loop.

for (int i = 0; i < ChunkList.Capacity; i++)
{
    if (ChunkList[i].UniqueID == ChunkID)
    {
        ChunkList.Remove(i);
    }
}

You can, and should, however, use linq:

ChunkList.Remove(x => x.UniqueID == ChunkID);

aggfunc=pd.Series.nunique will only count unique values for a series - in this case count the unique values for a column. But this doesn't quite reflect as an alternative to aggfunc='count'

For simple counting, it better to use aggfunc=pd.Series.count

If you are using Scene Builder, you will see at the right an accordion panel which normally has got three options ("Properties", "Layout" and "Code"). In the second one ("Layout"), you will see an option called "[parent layout] Constraints" (in your case "AnchorPane Constrainsts").

You should put "0" in the four sides of the element wich represents the parent layout.

Another more exotic way to solve this issue is to use bcadd() with a dummy value for the $right_operand of 0.

$formatted_number = bcadd($number, 0, 2);

The two previous answers demonstrate how to use Canvas and ImageData. I would like to propose an answer with runnable example and using an image processing framework, so you don't need to handle the pixel data manually.

MarvinJ provides the method image.getAlphaComponent(x,y) which simply returns the transparency value for the pixel in x,y coordinate. If this value is 0, pixel is totally transparent, values between 1 and 254 are transparency levels, finally 255 is opaque.

For demonstrating I've used the image below (300x300) with transparent background and two pixels at coordinates (0,0) and (150,150).

Console output:

(0,0): TRANSPARENT
(150,150): NOT_TRANSPARENT

image = new MarvinImage();_x000D_
image.load("https://i.imgur.com/eLZVbQG.png", imageLoaded);_x000D_
_x000D_
function imageLoaded(){_x000D_
  console.log("(0,0): "+(image.getAlphaComponent(0,0) > 0 ? "NOT_TRANSPARENT" : "TRANSPARENT"));_x000D_
  console.log("(150,150): "+(image.getAlphaComponent(150,150) > 0 ? "NOT_TRANSPARENT" : "TRANSPARENT"));_x000D_
}

I know it's a little late for this. But I always thought that the best way to create event listeners is directly from JavaScript. Kind of like not applying inline CSS styles.

function validate(){
    //do stuff
}
function init(){
    document.getElementById('form').onsubmit = validate;
}
window.onload = init;

That way you don't have a bunch of event listeners throughout your HTML.

Use a combination of Microsoft specific CSS rules to filter IE11:

<!doctype html>
<html>
 <head>
  <title>IE10/11 Media Query Test</title>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <style>
    @media all and (-ms-high-contrast:none)
     {
     .foo { color: green } /* IE10 */
     *::-ms-backdrop, .foo { color: red } /* IE11 */
     }
  </style>
 </head>
 <body>
  <div class="foo">Hi There!!!</div>
 </body>
</html>

Filters such as this work because of the following:

When a user agent cannot parse the selector (i.e., it is not valid CSS 2.1), it must ignore the selector and the following declaration block (if any) as well.

<!doctype html>_x000D_
<html>_x000D_
 <head>_x000D_
  <title>IE10/11 Media Query Test</title>_x000D_

Update: text-overflow: ellipsis is now supported as of Firefox 7 (released September 27th 2011). Yay! My original answer follows as a historical record.

Justin Maxwell has cross browser CSS solution. It does come with the downside however of not allowing the text to be selected in Firefox. Check out his guest post on Matt Snider's blog for the full details on how this works.

Note this technique also prevents updating the content of the node in JavaScript using the innerHTML property in Firefox. See the end of this post for a workaround.

CSS

.ellipsis {
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
    -o-text-overflow: ellipsis;
    -moz-binding: url('assets/xml/ellipsis.xml#ellipsis');
}

ellipsis.xml file contents

  xmlns:xbl="http://www.mozilla.org/xbl"
  xmlns:xul="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"

            <xul:window>
                <xul:description crop="end" xbl:inherits="value=xbl:text"><children/></xul:description>
            </xul:window>
        </content>
    </binding>
</bindings>

Updating node content

To update the content of a node in a way that works in Firefox use the following:

var replaceEllipsis(node, content) {
    node.innerHTML = content;
    // use your favorite framework to detect the gecko browser
    if (YAHOO.env.ua.gecko) {
        var pnode = node.parentNode,
            newNode = node.cloneNode(true);

        pnode.replaceChild(newNode, node);
    }
};

See Matt Snider's post for an explanation of how this works.

If you want to redirect all non-www requests to your site to the www version, all you need to do is add the following code to your .htaccess file:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

Connection reset simply means that a TCP RST was received. This happens when your peer receives data that it can't process, and there can be various reasons for that.

The simplest is when you close the socket, and then write more data on the output stream. By closing the socket, you told your peer that you are done talking, and it can forget about your connection. When you send more data on that stream anyway, the peer rejects it with an RST to let you know it isn't listening.

In other cases, an intervening firewall or even the remote host itself might "forget" about your TCP connection. This could happen if you don't send any data for a long time (2 hours is a common time-out), or because the peer was rebooted and lost its information about active connections. Sending data on one of these defunct connections will cause a RST too.

Update in response to additional information:

Take a close look at your handling of the SocketTimeoutException. This exception is raised if the configured timeout is exceeded while blocked on a socket operation. The state of the socket itself is not changed when this exception is thrown, but if your exception handler closes the socket, and then tries to write to it, you'll be in a connection reset condition. setSoTimeout() is meant to give you a clean way to break out of a read() operation that might otherwise block forever, without doing dirty things like closing the socket from another thread.

There is a way, although not very elegant:

1. ansible-playbook roles/hadoop_primary/tasks/hadoop_master.yml --step --start-at-task='start hadoop jobtracker services'
2. You will get a prompt: Perform task: start hadoop jobtracker services (y/n/c)
3. Answer y
4. You will get a next prompt, press Ctrl-C

The answer @Boris gave is correct 99% of the time, however it can also happen if you open the workspace in an older version of Eclipse. A workspace imported into/created with Juno will throw this error when opened in Galileo.

You need to either transpile/compile that JSX code to javascript or use the in-browser transformator

Look at http://facebook.github.io/react/docs/getting-started.html and take note of the <script> tags, you need those included for JSX to work in the browser.

It's kind of pointless to talk about "database performance", "query performance" is a better term here. And the answer is: it depends on the query, data that it operates on, indexes, hardware, etc. You can get an idea of how many rows are going to be scanned and what indexes are going to be used with EXPLAIN syntax.

2GB does not really count as a "large" database - it's more of a medium size.

This is ancient history but I just ran into this issue and the fix for me was recycling the application pool of the website in IIS. Easy fix, for once.

This should get you started:

R> qplot(hwy, cty, data = mpg) + 
       facet_grid(. ~ manufacturer) + 
       theme(strip.text.x = element_text(size = 8, colour = "orange", angle = 90))

See also this question: How can I manipulate the strip text of facet plots in ggplot2?

$( "#tabs" ).tabs( "option", "active" )

then you will have the index of tab from 0

Since the integration of OpenCV is such an effort, we pre-packaged it and published it via JCenter here: https://github.com/quickbirdstudios/opencv-android

Just include this in your module's build.gradle dependencies section

dependencies {
  implementation 'com.quickbirdstudios:opencv:3.4.1'
}

and this in your project's build.gradle repositories section

repositories {
  jcenter()
}

You won't get lint error after gradle import but don't forget to initialize the OpenCV library like this in MainActivity

public class MainActivity extends Activity {
    static {

Tip: update_attribute is being deprecated in Rails 4 via Commit a7f4b0a1. It removes update_attribute in favor of update_column.

There are a few things wrong here:

• First, terminology. "Epoch" refers to the starting point of something. The "Unix Epoch" is Midnight, January 1st 1970 UTC. You can't convert an arbitrary "date string to epoch". You probably meant "Unix Time", which is often erroneously called "Epoch Time".

• .unix() returns Unix Time in whole seconds, but the default moment constructor accepts a timestamp in milliseconds. You should instead use .valueOf() to return milliseconds. Note that calling .unix()*1000 would also work, but it would result in a loss of precision.

• You're parsing a string without providing a format specifier. That isn't a good idea, as values like 1/2/2014 could be interpreted as either February 1st or as January 2nd, depending on the locale of where the code is running. (This is also why you get the deprecation warning in the console.) Instead, provide a format string that matches the expected input, such as:

  moment("10/15/2014 9:00", "M/D/YYYY H:mm")
  

• .calendar() has a very specific use. If you are near to the date, it will return a value like "Today 9:00 AM". If that's not what you expected, you should use the .format() function instead. Again, you may want to pass a format specifier.

• To answer your questions in comments, No - you don't need to call .local() or .utc().

Putting it all together:

var ts = moment("10/15/2014 9:00", "M/D/YYYY H:mm").valueOf();
var m = moment(ts);
var s = m.format("M/D/YYYY H:mm");
alert("Values are: ts = " + ts + ", s = " + s);

On my machine, in the US Pacific time zone, it results in:

Values are: ts = 1413388800000, s = 10/15/2014 9:00

Since the input value is interpreted in terms of local time, you will get a different value for ts if you are in a different time zone.

Also note that if you really do want to work with whole seconds (possibly losing precision), moment has methods for that as well. You would use .unix() to return the timestamp in whole seconds, and moment.unix(ts) to parse it back to a moment.

var ts = moment("10/15/2014 9:00", "M/D/YYYY H:mm").unix();
var m = moment.unix(ts);

For me, dataBinding { enabled true } was enabled in gradle, removing this helped me

document.FormName.btnSubmit.click(); 

works for me. Enjoy.

Since this thread is one of the top results for that error and has no fix yet, I'll post what I found to fix it, originally found in this thread: Build Failure? "Unable to start program... The system cannot find the file specificed" which lead me to this thread: Error 'LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt' after installing Visual Studio 2012 Release Preview

Basically all I did is this: Project Properties -> Configuration Properties -> Linker (General) -> Enable Incremental Linking -> "No (/INCREMENTAL:NO)"

Applying same filter in HTML with multiple columns, just example:

 variable = (array | filter : {Lookup1Id : subject.Lookup1Id, Lookup2Id : subject.Lookup2Id} : true)

df.isna() return True values for NaN, False for the rest. So, doing:

df.isna().any()

will return True for any column having a NaN, False for the rest

If anything, I'd expect the code to be less efficient than when leaving it out.

Calling the Clear() methods are unnecessary, and the GC probably wouldn't do that if the Dispose didn't do it...

var iframe = document.getElementById('iframe');
  $(iframe).contents().find("html").html();

you can use ->addOrderBy($sort, $order)

Add:Doctrine Querybuilder btw. often uses "special" modifications of the normal methods, see select-addSelect, where-andWhere-orWhere, groupBy-addgroupBy...

I often use a blank label as the TargetControlID. ex. <asp:Label ID="lblghost" runat="server" Text="" />

I've seen two things that cause the click event not fire:
1. you have to remove the OKControlID (as others have mentioned)
2. If you are using field validators you should add CausesValidation="false" on the button.

Both scenarios behaved the same way for me.

Guys this is a generic method you can use for all your tables, Worked perfectly in my case.

public void deleteRowFromTable(String tableName, String columnName, String keyValue) {
    String whereClause = columnName + "=?";
    String[] whereArgs = new String[]{String.valueOf(keyValue)};
    yourDatabase.delete(tableName, whereClause, whereArgs);
}

I believe that your problem is that you're checking for an empty string using double quotes instead of single quotes. Try just changing to:

DELETE FROM table WHERE edit_user=''

How to do it with Oracle SQL Developer: In the Left pane, under the connections you will find "Sequences", right click and select create a new sequence from the context sensitive pop up. Fill out the details: Schema name, sequence_name, properties(start with value, min value, max value, increment value etc.) and click ok. Assuming that you have a table with a key that uses this auto_increment, while inserting in this table just give "your_sequence_name.nextval" in the field that utilizes this property. I guess this should help! :)

This came across while working on a project on linux platform.

exec('wget http://<url to the php script>)

This runs as if you run the script from browser.

Hope this helps!!

Simply pass the sorted items from the dictionary to the plot() function. concentration.items() returns a list of tuples where each tuple contains a key from the dictionary and its corresponding value.

You can take advantage of list unpacking (with *) to pass the sorted data directly to zip, and then again to pass it into plot():

import matplotlib.pyplot as plt

concentration = {
    0: 0.19849878712984576,
    5000: 0.093917341754771386,
    10000: 0.075060643507712022,
    20000: 0.06673074282575861,
    30000: 0.057119318961966224,
    50000: 0.046134834546203485,
    100000: 0.032495766396631424,
    200000: 0.018536317451599615,
    500000: 0.0059499290585381479}

plt.plot(*zip(*sorted(concentration.items())))
plt.show()

sorted() sorts tuples in the order of the tuple's items so you don't need to specify a key function because the tuples returned by dict.item() already begin with the key value.

You are doing everything right, except passing your bundle path to asset() function.

According to documentation - in your example this should look like below:

{{ asset('bundles/webshome/css/main.css') }}

Tip: you also can call assets:install with --symlink key, so it will create symlinks in web folder. This is extremely useful when you often apply js or css changes (in this way your changes, applied to src/YouBundle/Resources/public will be immediately reflected in web folder without need to call assets:install again):

app/console assets:install web --symlink

Also, if you wish to add some assets in your child template, you could call parent() method for the Twig block. In your case it would be like this:

{% block stylesheets %}
    {{ parent() }}

    <link href="{{ asset('bundles/webshome/css/main.css') }}" rel="stylesheet">
{% endblock %}

scanf needs to know the size of the data being pointed at by &d to fill it properly, whereas variadic functions promote floats to doubles (not entirely sure why), so printf is always getting a double.

Because your button is in control it could be that there is a validation from another control that don't allow the button to submit. The result in my case was to add CausesValidation property to the button:

<asp:Button ID="btn_QuaSave" runat="server" Text="SAVE" OnClick="btn_QuaSave_Click" CausesValidation="False"/>

I have tried all the above mentioned options but can not find the solution to this problem . Then I got its solution.... This error is flashed when we are trying to open mysql with out stating the service. Follow the bellow mentioned steps..
STEP 1
Open cmd prompt
to start the service type
mysqld --console this will start the mysql service
enter image description here
STEP 2 dont close this cmd prompt
now open new cmd prompt and type
mysql -u root -p
then enter ur password

      if ( x > y && x > z )
         System.out.println("First number is largest.");
      else if ( y > x && y > z )
         System.out.println("Second number is largest.");
      else if ( z > x && z > y )

JavaScript arrays are designed to hold data with numeric indexes. You can add named properties to them because an array is a type of object (and this can be useful when you want to store metadata about an array which holds normal, ordered, numerically indexed data), but that isn't what they are designed for.

The JSON array data type cannot have named keys on an array.

When you pass a JavaScript array to JSON.stringify the named properties will be ignored.

If you want named properties, use an Object, not an Array.

const test = {}; // Object_x000D_
test.a = 'test';_x000D_
test.b = []; // Array_x000D_
test.b.push('item');_x000D_
test.b.push('item2');_x000D_
test.b.push('item3');_x000D_
test.b.item4 = "A value"; // Ignored by JSON.stringify_x000D_
const json = JSON.stringify(test);_x000D_
console.log(json);

For a very simple solution for numeric date for use in filenames use the following code:

set month=%date:~4,2%
set day=%date:~7,2%
set curTimestamp=%month%%day%%year%

rem then the you can add a prefix and a file extension easily like this
echo updates%curTimestamp%.txt

I use this code piece while working with indexes for radio group:

radioGroup.check(radioGroup.getChildAt(index).getId());

It's pretty simple. Both will increment the value of a variable. The following two lines are equal:

x++;
++x;

The difference is if you are using the value of a variable being incremented:

x = y++;
x = ++y;

Here, both lines increment the value of y by one. However, the first one assigns the value of y before the increment to x, and the second one assigns the value of y after the increment to x.

So there's only a difference when the increment is also being used as an expression. The post-increment increments after returning the value. The pre-increment increments before.

Solution 1:

  clang++ your.cpp

Solution 2:

  clang your.cpp -lstdc++

Solution 3:

   clang -x c++ your.cpp

Platform independent solution in one line is

Python 2:

python -c "import sys; print sys.executable"

Python 3:

python -c "import sys; print(sys.executable)"

Unless your compiler is different than the one supplied with the Mac XCode Dev tools, just follow the instructions in section 5.1 of Getting Started Guide for Unix Variants. The configuration and building of the latest source couldn't be easier, and it took all about about 1 minute to configure and 10 minutes to compile.

Another recently popular packages is : axios

Install : npm install axios --save

Simple Promise based requests

axios.post('/user', {
    firstName: 'Fred',
    lastName: 'Flintstone'
  })
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });

I recommend the following syntax for readability.

<? if ($condition): ?>
  <p>Content</p>
<? elseif ($other_condition): ?>
  <p>Other Content</p>
<? else: ?>
  <p>Default Content</p>
<? endif; ?>

Note, omitting php on the open tags does require that short_open_tags is enabled in your configuration, which is the default. The relevant curly-brace-free conditional syntax is always enabled and can be used regardless of this directive.

The simplest way I know ( str_getcsv ), it will import a CSV file into an array.

$csv = array_map('str_getcsv', file('data.csv'));

My answer is "neither one".

I believe the most "Pythonic" way to do things is to NOT check beforehand if the key is in a dictionary and instead just write code that assumes it's there and catch any KeyErrors that get raised because it wasn't.

This is usually done with enclosing the code in a try...except clause and is a well-known idiom usually expressed as "It's easier to ask forgiveness than permission" or with the acronym EAFP, which basically means it is better to try something and catch the errors instead for making sure everything's OK before doing anything. Why validate what doesn't need to be validated when you can handle exceptions gracefully instead of trying to avoid them? Because it's often more readable and the code tends to be faster if the probability is low that the key won't be there (or whatever preconditions there may be).

Of course, this isn't appropriate in all situations and not everyone agrees with the philosophy, so you'll need to decide for yourself on a case-by-case basis. Not surprisingly the opposite of this is called LBYL for "Look Before You Leap".

As a trivial example consider:

if 'name' in dct:
    value = dct['name'] * 3
else:
    logerror('"%s" not found in dictionary, using default' % name)
    value = 42

vs

try:
    value = dct['name'] * 3
except KeyError:
    logerror('"%s" not found in dictionary, using default' % name)
    value = 42

Although in the case it's almost exactly the same amount of code, the second doesn't spend time checking first and is probably slightly faster because of it (try...except block isn't totally free though, so it probably doesn't make that much difference here).

Generally speaking, testing in advance can often be much more involved and the savings gain from not doing it can be significant. That said, if 'name' in dict: is better for the reasons stated in the other answers.

If you're interested in the topic, this message titled "EAFP vs LBYL (was Re: A little disappointed so far)" from the Python mailing list archive probably explains the difference between the two approached better than I have here. There's also a good discussion about the two approaches in the book Python in a Nutshell, 2nd Ed by Alex Martelli in chapter 6 on Exceptions titled Error-Checking Strategies. (I see there's now a newer 3rd edition, publish in 2017, which covers both Python 2.7 and 3.x).

When you are installing Android Studio, under Install type do not use standard setting, use custom setting instead, and check all the option boxes in the next step.

Nice explanation from http://www.journaldev.com/753/how-to-copy-arrays-in-java

Java Array Copy Methods

Object.clone(): Object class provides clone() method and since array in java is also an Object, you can use this method to achieve full array copy. This method will not suit you if you want partial copy of the array.

System.arraycopy(): System class arraycopy() is the best way to do partial copy of an array. It provides you an easy way to specify the total number of elements to copy and the source and destination array index positions. For example System.arraycopy(source, 3, destination, 2, 5) will copy 5 elements from source to destination, beginning from 3rd index of source to 2nd index of destination.

Arrays.copyOf(): If you want to copy first few elements of an array or full copy of array, you can use this method. Obviously it’s not versatile like System.arraycopy() but it’s also not confusing and easy to use.

Arrays.copyOfRange(): If you want few elements of an array to be copied, where starting index is not 0, you can use this method to copy partial array.

I encountered with this error and just decrease gradle version and android plugin version to 5.1.1 and 3.4.2.

I would need to display the jobid, jobname and 5 fields called Priority1, Priority2, Priority3, Priority4. Priority5.

Something's wrong with your query design. You're showing a specific job in each row as well, and so you'll either have a situation where ever row has four priority columns with a '0' and one priority column with a '1' (the priority for that job) or you'll end up repeating the count for all priorities on every row.

What do you really want to show here?

// declarations.d.ts
export interface IMyTable {
      id: number;
      title: string;
      createdAt: Date;
      isDeleted: boolean
}
declare var Tes: IMyTable;
// call in annother page
console.log(Tes.id);

I've used PDFBox with good success. Here's a sample of what the code looks like (back from version 0.7.2), that likely came from one of the provided examples:

// load the document
System.out.println("Reading document: " + filename);
PDDocument doc = null;                                                                                                                                                                                                          
doc = PDDocument.load(filename);

// look at all the document information
PDDocumentInformation info = doc.getDocumentInformation();
COSDictionary dict = info.getDictionary();
List l = dict.keyList();
for (Object o : l) {
    //System.out.println(o.toString() + " " + dict.getString(o));
    System.out.println(o.toString());
}

// look at the document catalog
PDDocumentCatalog cat = doc.getDocumentCatalog();
System.out.println("Catalog:" + cat);

List<PDPage> lp = cat.getAllPages();
System.out.println("# Pages: " + lp.size());
PDPage page = lp.get(4);
System.out.println("Page: " + page);
System.out.println("\tCropBox: " + page.getCropBox());
System.out.println("\tMediaBox: " + page.getMediaBox());
System.out.println("\tResources: " + page.getResources());
System.out.println("\tRotation: " + page.getRotation());
System.out.println("\tArtBox: " + page.getArtBox());
System.out.println("\tBleedBox: " + page.getBleedBox());
System.out.println("\tContents: " + page.getContents());
System.out.println("\tTrimBox: " + page.getTrimBox());
List<PDAnnotation> la = page.getAnnotations();
System.out.println("\t# Annotations: " + la.size());

character varying(n), varchar(n) - (Both the same). value will be truncated to n characters without raising an error.

character(n), char(n) - (Both the same). fixed-length and will pad with blanks till the end of the length.

text - Unlimited length.

Example:

Table test:
   a character(7)
   b varchar(7)

insert "ok    " to a
insert "ok    " to b

We get the results:

a        | (a)char_length | b     | (b)char_length
----------+----------------+-------+----------------
"ok     "| 7              | "ok"  | 2

Right click your project and choose properties in the properties dialog check the Java Compiler settings, maybe you have different workspace settings.

Works the best. If you want to use it sitewide, without having to add this syntax to every class or ID, add the following CSS to your css body:

body { 
    -webkit-font-smoothing: antialiased;
    text-shadow: 1px 1px 1px rgba(0,0,0,0.004);
    background: url('./images/background.png');
    text-align: left;
    margin: auto;

}

I had this problem where I want a controller to end with a message such as 'Thanks for that form' and generic 'not found etc'. I do this under views->message->message_v.php

<?php
    $title = "Message";
    $this->load->view('templates/message_header', array("title" => $title));
?>
<h1>Message</h1>
<?php echo $msg_text; ?>
<h2>Thanks</h2>
<?php $this->load->view('templates/message_footer'); ?>

which allows me to change message rendering site wide in that single file for any thing that calls

$this->load->view("message/message_v", $data);

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
tbx.Text = "found!";

If Controls.Find is not found "textBox1" => error. You must add code.

If(tbx != null)

Edit:

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
If(tbx != null)
   tbx.Text = "found!";

Similar to what StuartLC was saying, my problem was not resolved until I enabled TCP/IP protocol under SQL Network Configuration>>Protocols for MSSQLSERVER in the SQL Server Configuration Manager dialogue box. After enabling this and a restart, my SSMS connected right away with just the instance name (no ~\MSSQLSERVER).

There is are multiple ways to execute the commands or script in the multiple remote Linux machines. One simple & easiest way is via pssh (parallel ssh program)

pssh: is a program for executing ssh in parallel on a number of hosts. It provides features such as sending input to all of the processes, passing a password to ssh, saving the output to files, and timing out.

Example & Usage:

Connect to host1 and host2, and print "hello, world" from each:

 pssh -i -H "host1 host2" echo "hello, world"

Run commands via a script on multiple servers:

pssh -h hosts.txt -P -I<./commands.sh

Usage & run a command without checking or saving host keys:

pssh -h hostname_ip.txt -x '-q -o StrictHostKeyChecking=no -o PreferredAuthentications=publickey -o PubkeyAuthentication=yes' -i  'uptime; hostname -f'

If the file hosts.txt has a large number of entries, say 100, then the parallelism option may also be set to 100 to ensure that the commands are run concurrently:

pssh -i -h hosts.txt -p 100 -t 0 sleep 10000

Options:
-I: Read input and sends to each ssh process.
-P: Tells pssh to display output as it arrives.
-h: Reads the host's file.
-H : [user@]host[:port] for single-host.
-i: Display standard output and standard error as each host completes
-x args: Passes extra SSH command-line arguments
-o option: Can be used to give options in the format used in the configuration file.(/etc/ssh/ssh_config) (~/.ssh/config)
-p parallelism: Use the given number as the maximum number of concurrent connections
-q Quiet mode: Causes most warning and diagnostic messages to be suppressed.
-t: Make connections time out after the given number of seconds. 0 means pssh will not timeout any connections

When ssh'ing to the remote machine, how to handle when it prompts for RSA fingerprint authentication.

Disable the StrictHostKeyChecking to handle the RSA authentication prompt.
-o StrictHostKeyChecking=no

Source: man pssh

you do not need to change any template for this work you just need to update the settings.py of your project. Go to the bottom of the settings.py and define this.

admin.site.site_header = 'My Site Admin'

In this way you would be able to change the header of the of the Django admin. Moreover you can read more about Django Admin customization and settings on the following link.

Optimization for emplace_back can be demonstrated in next example.

For emplace_back constructor A (int x_arg) will be called. And for push_back A (int x_arg) is called first and move A (A &&rhs) is called afterwards.

Of course, the constructor has to be marked as explicit, but for current example is good to remove explicitness.

#include <iostream>
#include <vector>
class A
{
public:
  A (int x_arg) : x (x_arg) { std::cout << "A (x_arg)\n"; }
  A () { x = 0; std::cout << "A ()\n"; }
  A (const A &rhs) noexcept { x = rhs.x; std::cout << "A (A &)\n"; }
  A (A &&rhs) noexcept { x = rhs.x; std::cout << "A (A &&)\n"; }

private:
  int x;
};

int main ()
{
  {
    std::vector<A> a;
    std::cout << "call emplace_back:\n";
    a.emplace_back (0);
  }
  {
    std::vector<A> a;
    std::cout << "call push_back:\n";
    a.push_back (1);
  }
  return 0;
}

output:

call emplace_back:
A (x_arg)

call push_back:
A (x_arg)
A (A &&)

I had the same question but about rather short vector<bool> (afaik the standard allows to implement it internally differently than just a continuous array of boolean elements). Hence I repeated the slightly modified tests by Fabio Fracassi. The results are as follows (times, in seconds):

            -O0       -O3
         --------  --------
memset     0.666     1.045
fill      19.357     1.066
iterator  67.368     1.043
assign    17.975     0.530
for i     22.610     1.004

So apparently for these sizes, vector<bool>::assign() is faster. The code used for tests:

#include <vector>
#include <cstring>
#include <cstdlib>

#define TEST_METHOD 5
const size_t TEST_ITERATIONS = 34359738;
const size_t TEST_ARRAY_SIZE = 200;

using namespace std;

int main(int argc, char** argv) {

    std::vector<int> v(TEST_ARRAY_SIZE, 0);

    for(size_t i = 0; i < TEST_ITERATIONS; ++i) {
#if TEST_METHOD == 1
        memset(&v[0], false, v.size() * sizeof v[0]);
#elif TEST_METHOD == 2
        std::fill(v.begin(), v.end(), false);
   #elif TEST_METHOD == 3
        for (std::vector<int>::iterator it=v.begin(), end=v.end(); it!=end; ++it) {
            *it = 0;
        }
   #elif TEST_METHOD == 4
      v.assign(v.size(),false);
   #elif TEST_METHOD == 5
      for (size_t i = 0; i < TEST_ARRAY_SIZE; i++) {
          v[i] = false;
      }
#endif
    }

    return EXIT_SUCCESS;
}

'%.2E' % Decimal('40800000000.00000000000000')

# returns '4.08E+10'

In your '40800000000.00000000000000' there are many more significant zeros that have the same meaning as any other digit. That's why you have to tell explicitly where you want to stop.

If you want to remove all trailing zeros automatically, you can try:

def format_e(n):
    a = '%E' % n
    return a.split('E')[0].rstrip('0').rstrip('.') + 'E' + a.split('E')[1]

format_e(Decimal('40800000000.00000000000000'))
# '4.08E+10'

format_e(Decimal('40000000000.00000000000000'))
# '4E+10'

format_e(Decimal('40812300000.00000000000000'))
# '4.08123E+10'

function update(datetime = "2017-01-01 05:11:58") {
    var theevent = new Date(datetime);
    now = new Date();
    var sec_num = (theevent - now) / 1000;
    var days    = Math.floor(sec_num / (3600 * 24));
    var hours   = Math.floor((sec_num - (days * (3600 * 24)))/3600);
    var minutes = Math.floor((sec_num - (days * (3600 * 24)) - (hours * 3600)) / 60);
    var seconds = Math.floor(sec_num - (days * (3600 * 24)) - (hours * 3600) - (minutes * 60));

    if (hours   < 10) {hours   = "0"+hours;}
    if (minutes < 10) {minutes = "0"+minutes;}
    if (seconds < 10) {seconds = "0"+seconds;}

    return  days+':'+ hours+':'+minutes+':'+seconds;
}

I tried all the solutions above, it fixes the issue sometimes, but still from time to time I happened to get stuck with the "Waiting for the debugger to attach" message box.

The final solution in my case was to unplug all the Android devices but the one I want to debug on. I don't know which one is the culprit: the Nexus 7 running JB 4.2, the HTC One X running ICS, the HTC Desire S running Gingerbread, or the combintation of the 3, but as soon as I only have one device plugged in, it runs smooth as silk.

select sum([rows])
from sys.partitions
where object_id=object_id('tablename')
 and index_id in (0,1)

is very fast but very rarely inaccurate.

I know this is a bit old, but in case another beginner is going through this, I'll share some code that covers a bit more of the basic operations, here is another example that also includes the option to cancel the process and also report to the user the status of the process. I'm going to add on top of the code given by Alex Aza in the solution above

public Form1()
{
    InitializeComponent();

    backgroundWorker1.DoWork += backgroundWorker1_DoWork;
    backgroundWorker1.ProgressChanged += backgroundWorker1_ProgressChanged;
    backgroundWorker1.RunWorkerCompleted += backgroundWorker1_RunWorkerCompleted;  //Tell the user how the process went
    backgroundWorker1.WorkerReportsProgress = true;
    backgroundWorker1.WorkerSupportsCancellation = true; //Allow for the process to be cancelled
}

//Start Process
private void button1_Click(object sender, EventArgs e)
{
    backgroundWorker1.RunWorkerAsync();
}

//Cancel Process
private void button2_Click(object sender, EventArgs e)
{
    //Check if background worker is doing anything and send a cancellation if it is
    if (backgroundWorker1.IsBusy)
    {
        backgroundWorker1.CancelAsync();
    }

}

private void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
    for (int i = 0; i < 100; i++)
    {
        Thread.Sleep(1000);
        backgroundWorker1.ReportProgress(i);

        //Check if there is a request to cancel the process
        if (backgroundWorker1.CancellationPending)
        {
            e.Cancel = true;
            backgroundWorker1.ReportProgress(0);
            return;
        }
    }
    //If the process exits the loop, ensure that progress is set to 100%
    //Remember in the loop we set i < 100 so in theory the process will complete at 99%
    backgroundWorker1.ReportProgress(100);
}

private void backgroundWorker1_ProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e)
{
    progressBar1.Value = e.ProgressPercentage;
}

private void backgroundWorker1_RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e)
{
    if (e.Cancelled)
    {
         lblStatus.Text = "Process was cancelled";
    }
    else if (e.Error != null)
    {
         lblStatus.Text = "There was an error running the process. The thread aborted";
    }
    else
    {
       lblStatus.Text = "Process was completed";
    }
}

In Python-style regex, \d matches any individual digit. If you're seeing something that doesn't seem to do that, please provide the full regex you're using, as opposed to just describing that one particular symbol.

>>> import re
>>> re.match(r'\d', '3')
<_sre.SRE_Match object at 0x02155B80>
>>> re.match(r'\d', '2')
<_sre.SRE_Match object at 0x02155BB8>
>>> re.match(r'\d', '1')
<_sre.SRE_Match object at 0x02155B80>

From the spec, §15.9.1.1:

A Date object contains a Number indicating a particular instant in time to within a millisecond. Such a Number is called a time value. A time value may also be NaN, indicating that the Date object does not represent a specific instant of time.

Time is measured in ECMAScript in milliseconds since 01 January, 1970 UTC. In time values leap seconds are ignored. It is assumed that there are exactly 86,400,000 milliseconds per day. ECMAScript Number values can represent all integers from –9,007,199,254,740,992 to 9,007,199,254,740,992; this range suffices to measure times to millisecond precision for any instant that is within approximately 285,616 years, either forward or backward, from 01 January, 1970 UTC.

The actual range of times supported by ECMAScript Date objects is slightly smaller: exactly –100,000,000 days to 100,000,000 days measured relative to midnight at the beginning of 01 January, 1970 UTC. This gives a range of 8,640,000,000,000,000 milliseconds to either side of 01 January, 1970 UTC.

The exact moment of midnight at the beginning of 01 January, 1970 UTC is represented by the value +0.

The third paragraph being the most relevant. Based on that paragraph, we can get the precise earliest date per spec from new Date(-8640000000000000), which is Tuesday, April 20th, 271,821 BCE (BCE = Before Common Era, e.g., the year -271,821).

This is Correct way to get ##

function getTime(offset)
        {
            var d = new Date();
            localTime = d.getTime();
            localOffset = d.getTimezoneOffset() * 60000;

            // obtain UTC time in msec
            utc = localTime + localOffset;
            // create new Date object for different city
            // using supplied offset
            var nd = new Date(utc + (3600000*offset));
            //nd = 3600000 + nd;
            utc = new Date(utc);
            // return time as a string
            $("#local").html(nd.toLocaleString());
            $("#utc").html(utc.toLocaleString());
        }

It doesn't need to request react router. This action can be done natively and it is provided by the browser.

just use window.location

class RedirectPage extends React.Component {
  componentDidMount(){
    window.location.replace('https://www.google.com')
  }
}

also, if you want to open it in a new tab:

window.open('https://www.google.com', '_blank');

I'm a fan of the Find-In-Files dialog in Notepad++. Bonus: It's free.

You can use simple form:

@using(Html.BeginForm("Update", "Shopping"))
{
    <input type="text" id="ss" name="qty" value="@item.Quantity"/>
    ...
    <input type="submit" value="Update" />
}

And add here attribute:

[HttpPost]
public ActionResult Update(string id, string productid, int qty, decimal unitrate)

What causes a "broken pipe", and more importantly, is it possible to recover from that state?

It is caused by something causing the connection to close. (It is not your application that closed the connection: that would have resulted in a different exception.)

It is not possible to recover the connection. You need to open a new one.

If it cannot be recovered, it seems this would be a good sign that an irreversible problem has occurred and that I should simply close this socket connection. Is that a reasonable assumption?

Yes it is. Once you've received that exception, the socket won't ever work again. Closing it is is the only sensible thing to do.

Is there ever a time when this IOException would occur while the socket connection is still being properly connected in the first place (rather than a working connection that failed at some point)?

No. (Or at least, not without subverting proper behavior of the OS'es network stack, the JVM and/or your application.)

Is it wise to always call SocketChannel.isConnected() before attempting a SocketChannel.write() ...

In general, it is a bad idea to call r.isXYZ() before some call that uses the (external) resource r. There is a small chance that the state of the resource will change between the two calls. It is a better idea to do the action, catch the IOException (or whatever) resulting from the failed action and take whatever remedial action is required.

In this particular case, calling isConnected() is pointless. The method is defined to return true if the socket was connected at some point in the past. It does not tell you if the connection is still live. The only way to determine if the connection is still alive is to attempt to use it; e.g. do a read or write.

When you get a UnicodeEncodeError, it means that somewhere in your code you convert directly a byte string to a unicode one. By default in Python 2 it uses ascii encoding, and utf8 encoding in Python3 (both may fail because not every byte is valid in either encoding)

To avoid that, you must use explicit decoding.

If you may have 2 different encoding in your input file, one of them accepts any byte (say UTF8 and Latin1), you can try to first convert a string with first and use the second one if a UnicodeDecodeError occurs.

def robust_decode(bs):
    '''Takes a byte string as param and convert it into a unicode one.
First tries UTF8, and fallback to Latin1 if it fails'''
    cr = None
    try:
        cr = bs.decode('utf8')
    except UnicodeDecodeError:
        cr = bs.decode('latin1')
    return cr

If you do not know original encoding and do not care for non ascii character, you can set the optional errors parameter of the decode method to replace. Any offending byte will be replaced (from the standard library documentation):

Replace with a suitable replacement character; Python will use the official U+FFFD REPLACEMENT CHARACTER for the built-in Unicode codecs on decoding and ‘?’ on encoding.

bs.decode(errors='replace')

You're thinking too complicated. It's actually just $('#'+openaddress).

Single query that will return time difference of two timestamp columns:

Note: Obviously, this is a simple example explaining just how to set up a CtrlC handler, but as always there are rules that need to be obeyed in order not to break something else. Please read the comments below.

The sample code from above:

#include  <stdio.h>
#include  <signal.h>
#include  <stdlib.h>

void     INThandler(int);

int  main(void)
{
     signal(SIGINT, INThandler);
     while (1)
          pause();
     return 0;
}

void  INThandler(int sig)
{
     char  c;

     signal(sig, SIG_IGN);
     printf("OUCH, did you hit Ctrl-C?\n"
            "Do you really want to quit? [y/n] ");
     c = getchar();
     if (c == 'y' || c == 'Y')
          exit(0);
     else
          signal(SIGINT, INThandler);
     getchar(); // Get new line character
}

C++ uses structs primarily for 1) backwards compatibility with C and 2) POD types. C structs do not have methods, inheritance or visibility.

You can with flexbox:

ul.list {
    padding: 0;
    list-style: none;
    display: flex;
    align-items: stretch;
    justify-items: center;
    flex-wrap: wrap;
    justify-content: center;
}
li {
    width: 100px;
    padding: .5rem;
    border-radius: 1rem;
    background: yellow;
    margin: 0 5px;
}

<ul class="list">
  <li>title 1</li>
  <li>title 2<br>new line</li>
  <li>title 3<br>new<br>line</li>
</ul>

(IN @brugernavn varchar(64)**)**,IN @password varchar(64))

The problem is the )

Two possible approaches.

1. If you have a foreign key, declare it as on-delete-cascade and delete the parent rows older than 30 days. All the child rows will be deleted automatically.

2. Based on your description, it looks like you know the parent rows that you want to delete and need to delete the corresponding child rows. Have you tried SQL like this?

     delete from child_table
         where parent_id in (
              select parent_id from parent_table
                   where updd_tms != (sysdate-30)
   

   -- now delete the parent table records

   delete from parent_table
   where updd_tms != (sysdate-30);
   

---- Based on your requirement, it looks like you might have to use PL/SQL. I'll see if someone can post a pure SQL solution to this (in which case that would definitely be the way to go).

declare
    v_sqlcode number;
    PRAGMA EXCEPTION_INIT(foreign_key_violated, -02291);
begin
    for v_rec in (select parent_id, child id from child_table
                         where updd_tms != (sysdate-30) ) loop

    -- delete the children
    delete from child_table where child_id = v_rec.child_id;

    -- delete the parent. If we get foreign key violation, 
    -- stop this step and continue the loop
    begin
       delete from parent_table
          where parent_id = v_rec.parent_id;
    exception
       when foreign_key_violated
         then null;
    end;
 end loop;
end;

You want the following:

ALTER TABLE mytable MODIFY mycolumn VARCHAR(255);

Columns are nullable by default. As long as the column is not declared UNIQUE or NOT NULL, there shouldn't be any problems.

There's one way, but it might be disappointing: use an additional variable (or one of the table's field) for storing the count, and increase it every time you make an insertion.

count = 0
tbl = {}

tbl["test"] = 47
count = count + 1

tbl[1] = 48
count = count + 1

print(count)   -- prints "2"

There's no other way, the # operator will only work on array-like tables with consecutive keys.

This is your safest way to do it:

$id =101;
//$user_id=25;
$criteria=new CDbCriteria;
$criteria->condition="email_id < :email_id";
//$criteria->addCondition("user_id=:user_id");
$criteria->params=array(
  ':email_id' => $id,
  //':user_id' => $user_id,
);
$comments=EmailArchive::model()->findAll($criteria);

Note that if you comment out the commented lines you get a way to add more filtering to your search.

After this it is recommend to check if there is any data returned like:

if (isset($comments)) { // We found some comments, we can sleep well tonight
  // do comments process or whatever
}

dir 1>a.txt 2>&1 | type a.txt

This will help to redirect both STDOUT and STDERR

P.S. This, in fact, fully matches the answer in the referenced question.

To execute a python script in a bash script you need to call the same command that you would within a terminal. For instance

> python python_script.py var1 var2

To access these variables within python you will need

import sys
print sys.argv[0] # prints python_script.py
print sys.argv[1] # prints var1
print sys.argv[2] # prints var2

Go to your workspace folder

1. find .git folder
2. delete the folder and its contents
3. use git init command to initialize.

Now it will show what all the files can be committed.

You're confusing actual precision and display precision. Decimal rounding cannot be represented exactly in binary. You should try:

> np.set_printoptions(precision=2)
> np.array([5.333333])
array([ 5.33])

As of Spring 4.2.x, you can create custom mapping annotations, using @RequestMapping as a meta-annotation. So:

Is there a way to produce a "composite/inherited/aggregated" annotation with default values for consumes and produces, such that I could instead write something like:

@JSONRequestMapping(value = "/foo", method = RequestMethod.POST)

Yes, there is such a way. You can create a meta annotation like following:

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@RequestMapping(consumes = "application/json", produces = "application/json")
public @interface JsonRequestMapping {
    @AliasFor(annotation = RequestMapping.class, attribute = "value")
    String[] value() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "method")
    RequestMethod[] method() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "params")
    String[] params() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "headers")
    String[] headers() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "consumes")
    String[] consumes() default {};

    @AliasFor(annotation = RequestMapping.class, attribute = "produces")
    String[] produces() default {};
}

Then you can use the default settings or even override them as you want:

@JsonRequestMapping(method = POST)
public String defaultSettings() {
    return "Default settings";
}

@JsonRequestMapping(value = "/override", method = PUT, produces = "text/plain")
public String overrideSome(@RequestBody String json) {
    return json;
}

You can read more about AliasFor in spring's javadoc and github wiki.

The problem is

listModel.addElement(listaRosa.getSelectedValue());
listModel.removeElement(listaRosa.getSelectedValue());

you may be adding an element and immediatly removing it since both add and remove operations are on the same listModel.

Try

private void aggiungiTitolareButtonActionPerformed(java.awt.event.ActionEvent evt) {                                                       

    DefaultListModel lm2 = (DefaultListModel) listaTitolari.getModel();
    DefaultListModel lm1  = (DefaultListModel) listaRosa.getModel();
    if(lm2 == null)
    {
        lm2 = new DefaultListModel();
        listaTitolari.setModel(lm2);
    }
    lm2.addElement(listaTitolari.getSelectedValue());
    lm1.removeElement(listaTitolari.getSelectedValue());        
} 

I had parsing enum problem when i was trying to pass Nullable Enum that we get from Backend. Of course it was working when we get value, but it was problem when the null comes up.

java.lang.IllegalArgumentException: No enum constant

Also the problem was when we at Parcelize read moment write some short if.

My solution for this was

1.Create companion object with parsing method.

enum class CarsType {
    @Json(name = "SMALL")
    SMALL,
    @Json(name = "BIG")
    BIG;

    companion object {
        fun nullableValueOf(name: String?) = when (name) {
            null -> null
            else -> valueOf(name)
        }
    }
}

2. In Parcerable read place use it like this

data class CarData(
    val carId: String? = null,
    val carType: CarsType?,
    val data: String?
) : Parcelable {
    constructor(parcel: Parcel) : this(
        parcel.readString(),
        CarsType.nullableValueOf(parcel.readString()),
        parcel.readString())

        Dim result2 = From s In mySession.Query(Of CSucursal)()
                      Where (From c In mySession.Query(Of CCiudad)()
                             From cs In mySession.Query(Of CCiudadSucursal)()
                             Where cs.id_ciudad Is c
                             Where cs.id_sucursal Is s
                             Where c.id = IdCiudad
                             Where s.accion <> "E" AndAlso s.accion <> Nothing
                             Where cs.accion <> "E" AndAlso cs.accion <> Nothing
                             Select c.descripcion).Single() Is Nothing
                      Where s.accion <> "E" AndAlso s.accion <> Nothing
                      Select s.id, s.Descripcion

Shortest One Liner (also extremely fast):

 text.replace(/(^\w|\s\w)/g, m => m.toUpperCase());

Explanation:

• ^\w : first character of the string
• | : or
• \s\w : first character after whitespace
• (^\w|\s\w) Capture the pattern.
• g Flag: Match all occurrences.

If you want to make sure the rest is in lowercase:

text.replace(/(^\w|\s\w)(\S*)/g, (_,m1,m2) => m1.toUpperCase()+m2.toLowerCase())

I solved the problem switching the workspace.

1. Go to File (Switch workspace)
2. Select the destination and create a folder named Workspace
3. Run a Hello World and close Eclipse (notice that Eclipse creates the folder RemoteSystemsTempFiles automatically)
4. now copy all your projects into the new folder Workspace
5. Open Eclipse and if necessary (sometimes Eclipse does not show the projects) import all of them (go to File/ Open projects from File System)

For added new element into the array, push() should be the answer.

For remove element and update state of array, below code works for me. splice(index, 1) can not work.

const [arrayState, setArrayState] = React.useState<any[]>([]);
...

// index is the index for the element you want to remove
const newArrayState = arrayState.filter((value, theIndex) => {return index !== theIndex});
setArrayState(newArrayState);

You can do it using xml.

Create an xml layout and name it like my_edit_text_border.xml

 <?xml version="1.0" encoding="utf-8"?>

    android:layout_height="wrap_content"
    android:layout_width="wrap_content">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="#ffffff"/>
            <corners android:radius="5dp" />
            <stroke
                android:width="2dp"
                android:color="#949494"
                />

This is just Microsoft being cheeky. "Deprecated" implies a language feature that may not be provided in future versions of the standard language / standard libraries, as decreed by the standards committee. It does not, or should not mean, "we, unilaterally, don't think you should use it", no matter how well-founded that advice is.

I would also like to add something from me.

Other possible syntax to call functions with the ternary operator, would be:

(condition ? fn1 : fn2)();

It can be handy if you have to pass the same list of parameters to both functions, so you have to write them only once.

(condition ? fn1 : fn2)(arg1, arg2, arg3, arg4, arg5);

You can use the ternary operator even with member function names, which I personally like very much to save space:

$('.some-element')[showThisElement ? 'addClass' : 'removeClass']('visible');

or

$('.some-element')[(showThisElement ? 'add' : 'remove') + 'Class']('visible');

Another example:

var addToEnd = true; //or false
var list = [1,2,3,4];
list[addToEnd ? 'push' : 'unshift'](5);

You don't have to do anything special, it should just be working.

When I have a fresh rails app with this controller:

class FooController < ApplicationController
  def index
    raise "error"
  end
end

and go to http://127.0.0.1:3000/foo/

I am seeing the exception with a stack trace.

You might not see the whole stacktrace in the console log because Rails (since 2.3) filters lines from the stack trace that come from the framework itself.

See config/initializers/backtrace_silencers.rb in your Rails project

You can always do it with a break from a loop construct or a labeled break as specified in aioobies answer.

public static void main(String[] args) {
    do {
        try {
            // code..
            if (condition)
                break;
            // more code...
        } catch (Exception e) {

        }
    } while (false);
}

There is a small handful of programs that do that... TowerJ is one that comes to mind (I'll let you Google for it) but it costs significant money.

The most useful reference for this topic I found is at: http://mindprod.com/jgloss/nativecompiler.html

it mentions a few other products, and alternatives to achieve the same purpose.

If you are using Angular 7 or a previous version and you dont' have access to the clear() method, there is a way to achieve that without doing any loop:

yourFormGroup.controls.youFormArrayName = new FormArray([]);

If you're using Windows: Go to https://nodejs.org/en/download/, download latest .exe or .msi file and install to overwrite the old versions

If you're using Ubuntu or Linux: Uninstall node.js first then reinstall, e.g with Ubuntu ():

sudo apt-get remove nodejs

# assume node.js 8 is latest version
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install nodejs

node -v
npm -v

Remove node_modules in your project folder and npm install to make sure your application will run well on new node and npm version.

empty() needs to access the value by reference (in order to check whether that reference points to something that exists), and PHP before 5.5 didn't support references to temporary values returned from functions.

However, the real problem you have is that you use empty() at all, mistakenly believing that "empty" value is any different from "false".

Empty is just an alias for !isset($thing) || !$thing. When the thing you're checking always exists (in PHP results of function calls always exist), the empty() function is nothing but a negation operator.

PHP doesn't have concept of emptyness. Values that evaluate to false are empty, values that evaluate to true are non-empty. It's the same thing. This code:

$x = something();
if (empty($x)) …

and this:

$x = something();
if (!$x) …

has always the same result, in all cases, for all datatypes (because $x is defined empty() is redundant).

Return value from the method always exists (even if you don't have return statement, return value exists and contains null). Therefore:

if (!empty($r->getError()))

is logically equivalent to:

if ($r->getError())

You can ssh to your server and run this command

 ln -s /usr/share/phpmyadmin /var/www/phpmyadmin

It worked for me..

The right mental model for using mutexes: The mutex protects an invariant.

Why are you sure that this is really right mental model for using mutexes? I think right model is protecting data but not invariants.

The problem of protecting invariants presents even in single-threaded applications and has nothing common with multi-threading and mutexes.

Furthermore, if you need to protect invariants, you still may use binary semaphore wich is never recursive.

Visual Studio 2015 doesn't install C++ by default. You have to rerun the setup, select Modify and then check Programming Language -> C++

You can use str_pad for adding 0's

str_pad($month, 2, '0', STR_PAD_LEFT); 

string str_pad ( string $input , int $pad_length [, string $pad_string = " " [, int $pad_type = STR_PAD_RIGHT ]] )

The short answer is you can't.

I don't know any PHP syntax, but what I can tell you is that PHP is executed on the server and JavaScript is executed on the client (on the browser).

You're doing a $_GET, which is used to retrieve form values:

The built-in $_GET function is used to collect values in a form with method="get".

In other words, if on your page you had:

<form method="get" action="blah.php">
    <input name="test"></input>
</form>

Your $_GET call would retrieve the value in that input field.

So how to retrieve a value from JavaScript?

Well, you could stick the javascript value in a hidden form field...

<script type="text/javascript" charset="utf-8">
    var test = "tester";
    // find the 'test' input element and set its value to the above variable
    document.getElementByID("test").value = test;
</script>

... elsewhere on your page ...

<form method="get" action="blah.php">
    <input id="test" name="test" visibility="hidden"></input>
    <input type="submit" value="Click me!"></input>
</form>

Then, when the user clicks your submit button, he/she will be issuing a "GET" request to blah.php, sending along the value in 'test'.

if your code is as follows then also this error occurs

private Image GetImage(byte[] byteArray)
{
   using (var stream = new MemoryStream(byteArray))
   {
       return Image.FromStream(stream);
    }
}

The correct one is

private Image GetImage(byte[] byteArray)
{
   var stream = new MemoryStream(byteArray))
   return Image.FromStream(stream);        
}

This may be because we are returning from the using block

Take a look at Job Control on UNIX systems

If you don't have control of your shell, simply hitting ctrl + C should stop the process. If that doesn't work, you can try ctrl + Z and using the jobs and kill -9 %<job #> to kill it. The '-9' is a type of signal. You can man kill to see a list of signals.

What about something like this?

>>> bin(int('ff', base=16))
'0b11111111'

This will convert the hexadecimal string you have to an integer and that integer to a string in which each byte is set to 0/1 depending on the bit-value of the integer.

As pointed out by a comment, if you need to get rid of the 0b prefix, you can do it this way:

>>> bin(int('ff', base=16)).lstrip('0b')
'11111111'

or this way:

>>> bin(int('ff', base=16))[2:]
'11111111'

i recently experienced this issue when i was trying to build and suddenly the laptop battery ran out of charge. I just removed all the servers from eclipse and then restore it. after doing that, i re-built the war file and it worked.

In my case (new sql server install, newly created user) my user simply didn't have the necessary permission. I logged to the Management Studio as sa, then went to Security/Logins, right-click my username, Properties, then in the Server Roles section I checked sysadmin.

HQL supports coalesce, allowing for ugly workarounds like:

where coalesce(c.status, 'no-status') = coalesce(:status, 'no-status')

I do this a lot, and I don't have an insert key on my laptop, so I made my own keybinding for it. You can do this by opening Settings > IDE Settings > Keymap and navigating to Main menu > File > New... (I would recommend typing "new" into the search box - that will narrow it down considerably).

Then you can add a new keyboard shortcut for it by double clicking on that item and selecting Add Keyboard Shortcut.

reference :

Makefile.am -- a user input file to automake

configure.in -- a user input file to autoconf

autoconf generates configure from configure.in

automake gererates Makefile.in from Makefile.am

configure generates Makefile from Makefile.in

For ex:

$]
configure.in Makefile.in
$] sudo autoconf
configure configure.in Makefile.in ... 
$] sudo ./configure
Makefile Makefile.in

I think you should understand what delayed expansion is. The existing answers don't explain it (sufficiently) IMHO.

Typing SET /? explains the thing reasonably well:

Delayed environment variable expansion is useful for getting around the limitations of the current expansion which happens when a line of text is read, not when it is executed. The following example demonstrates the problem with immediate variable expansion:

set VAR=before
if "%VAR%" == "before" (
    set VAR=after
    if "%VAR%" == "after" @echo If you see this, it worked
)

would never display the message, since the %VAR% in BOTH IF statements is substituted when the first IF statement is read, since it logically includes the body of the IF, which is a compound statement. So the IF inside the compound statement is really comparing "before" with "after" which will never be equal. Similarly, the following example will not work as expected:

set LIST=
for %i in (*) do set LIST=%LIST% %i
echo %LIST%

in that it will NOT build up a list of files in the current directory, but instead will just set the LIST variable to the last file found. Again, this is because the %LIST% is expanded just once when the FOR statement is read, and at that time the LIST variable is empty. So the actual FOR loop we are executing is:

for %i in (*) do set LIST= %i

which just keeps setting LIST to the last file found.

Delayed environment variable expansion allows you to use a different character (the exclamation mark) to expand environment variables at execution time. If delayed variable expansion is enabled, the above examples could be written as follows to work as intended:

set VAR=before
if "%VAR%" == "before" (
    set VAR=after
    if "!VAR!" == "after" @echo If you see this, it worked
)

set LIST=
for %i in (*) do set LIST=!LIST! %i
echo %LIST%

Another example is this batch file:

@echo off
setlocal enabledelayedexpansion
set b=z1
for %%a in (x1 y1) do (
 set b=%%a
 echo !b:1=2!
)

This prints x2 and y2: every 1 gets replaced by a 2.

Without setlocal enabledelayedexpansion, exclamation marks are just that, so it will echo !b:1=2! twice.

Because normal environment variables are expanded when a (block) statement is read, expanding %b:1=2% uses the value b has before the loop: z2 (but y2 when not set).

The following line is exactly what is being looked for. This method has been included with API 21, therefore it works for API 21 and above.

edittext.setShowSoftInputOnFocus(false);

1. VARCHAR can store up to 2000 bytes of characters while VARCHAR2 can store up to 4000 bytes of characters.

2. If we declare datatype as VARCHAR then it will occupy space for NULL values. In the case of VARCHAR2 datatype, it will not occupy any space for NULL values. e.g.,

   name varchar(10)

will reserve 6 bytes of memory even if the name is 'Ravi__', whereas

name varchar2(10) 

will reserve space according to the length of the input string. e.g., 4 bytes of memory for 'Ravi__'.

Here, _ represents NULL.

NOTE: varchar will reserve space for null values and varchar2 will not reserve any space for null values.

I have not seen this mentioned in the previous issues, so let me throw out another possibility. It could be that IFItest is not reachable or simply does not exist. For example, if one has a number of configurations, each with its own database, it could be that the database name was not changed to the correct one for the current configuration.

What I did was created a validator that did the samething as angular for minLength except I added the trim()

import { Injectable } from '@angular/core';
import { AbstractControl, ValidatorFn, Validators } from '@angular/forms';


@Injectable()
export class ValidatorHelper {
    ///This is the guts of Angulars minLength, added a trim for the validation
    static minLength(minLength: number): ValidatorFn {
        return (control: AbstractControl): { [key: string]: any } => {
            if (ValidatorHelper.isPresent(Validators.required(control))) {
                return null;
            }
             const v: string = control.value ? control.value : '';
            return v.trim().length < minLength ?
                { 'minlength': { 'requiredLength': minLength, 'actualLength': v.trim().length } } :
                null;
        };
    }

    static isPresent(obj: any): boolean {
        return obj !== undefined && obj !== null;
    }
}

I then in my app.component.ts overrode the minLength function provided by angular.

import { Component, OnInit } from '@angular/core';    
import { ValidatorHelper } from 'app/common/components/validators/validator-helper';
import { Validators } from '@angular/forms';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'
})
export class AppComponent implements OnInit {  
  constructor() { }

  ngOnInit(): void {       
    Validators.minLength = ValidatorHelper.minLength;
  }
}

Now everywhere angular's minLength built in validator is used, it will use the minLength that you have created in the helper.

Validators.compose([
      Validators.minLength(2)         
    ]);

You don't need to define intersection. It's already a first-class part of set.

>>> b1 = [1,2,3,4,5,9,11,15]
>>> b2 = [4,5,6,7,8]
>>> set(b1).intersection(b2)
set([4, 5])

                objConn.Close();
                objConn.Dispose();
            }
            if (dt != null)
            {
                dt.Dispose();
            }
        }

    }

you can use unlink to remove the symlink.

For Example:

cd ~/projects/node-redis 
npm link                 
cd ~/projects/node-bloggy
npm link redis             # links to your local redis

To reinstall from your package.json:

npm unlink redis
npm install

It's kind of ugly if the resizing code is almost as long as the code for building the graph in first place. So instead of resizing every element of the existing chart, why not simply reloading it? Here is how it worked for me:

function data_display(data){
   e = document.getElementById('data-div');
   var w = e.clientWidth;
   // remove old svg if any -- otherwise resizing adds a second one
   d3.select('svg').remove();
   // create canvas
   var svg = d3.select('#data-div').append('svg')
                                   .attr('height', 100)
                                   .attr('width', w);
   // now add lots of beautiful elements to your graph
   // ...
}

data_display(my_data); // call on page load

window.addEventListener('resize', function(event){
    data_display(my_data); // just call it again...
}

The crucial line is d3.select('svg').remove();. Otherwise each resizing will add another SVG element below the previous one.

If you want to add an empty folder you can add a '.keep' file in your folder.

This is because git does not care about folders.

You cannot delete everything with either rmdir or del alone:

• rmdir /s /q does not accept wildcard params. So rmdir /s /q * will error.
• del /s /f /q will delete all files, but empty subdirectories will remain.

My preferred solution (as I have used in many other batch files) is:

rmdir /s /q . 2>NUL

Instead of using a subquery, you could use two separate queries, one to get the number of rows and the other to select the random rows.

SELECT COUNT(id) FROM users; #id is the primary key

Then, get a random twenty rows.

$start_row = mt_rand(0, $total_rows - 20);

The final query:

SELECT * FROM users ORDER BY name ASC LIMIT $start_row, 20;

Great !! It has helped me a lot. I used to do the same using VB6 but now it is completely different. we should add this

listView1.View = System.Windows.Forms.View.Details;
listView1.GridLines = true; 
listView1.FullRowSelect = true;

Emitting handbuilt html like this is probably the best way so long as the markup isn't too complicated. The stringbuilder only starts to pay you back in terms of efficiency after about three concatenations, so for really simple stuff string + string will do.

Other than that you can start to use the html controls (System.Web.UI.HtmlControls) and render them, that way you can sometimes inherit them and make your own clasess for complex conditional layout.

With Tortoise SVN:

If you haven't committed your changes yet, you can do a revert on the parent folder where you deleted the file or directory.

If you have already committed the deleted file, then you can use the repository browser, change to the revision where the file still existed and then use the command Copy to... from the context menu. Enter the path to your working copy as the target and the deleted file will be copied from the repository to your working copy.

Try this:

 $(document).mouseup(function (e) {
    var div = $("#yourdivid");
    if (!div.is(e.target) && div.has(e.target).length === 0) 
    {
       div.hide();
     }
    });

You might also consider removing the need for duplicated parameter names in your Sql by changing your Sql to

table.Variable2 LIKE '%' || :VarB || '%'

and then getting your client to provide '%' for any value of VarB instead of null. In some ways I think this is more natural.

You could also change the Sql to

table.Variable2 LIKE '%' || IfNull(:VarB, '%') || '%'

The default is Ctrl + F6. You can change it by going to Window preferences. I usually change it to Ctrl + Tab, the same we use in switching tabs in a browser and other stuff.

First save the Excel spreadsheet as Unicode text. Open the TXT file using Internet explorer and click "Save as" TXT Encoding - choose the appropriate encoding, i.e. for Win Cyrillic 1251

You can try adding a question mark as below. This worked for me.

 componentWillReceiveProps(nextProps) {
    this.setState({
        title: nextProps?.blog?.title,
        body: nextProps?.blog?.content
     })
    }

Have a look this:

use yii\helpers\ArrayHelper; // load classes
use app\models\Course;
    .....
$dataList=ArrayHelper::map(Course::find()->asArray()->all(), 'id', 'name');
<?=$form->field($model, 'center_id')->dropDownList($dataList, 
         ['prompt'=>'-Choose a Course-']) ?>

I don't see this solution anywhere and supposedly ... according to one person, the proper way to do it is with copyPagesTo(). This does work I tested it. Your mileage may vary between city and open road driving. Goo luck.

    public static bool MergePDFs(List<string> lststrInputFiles, string OutputFile, out int iPageCount, out string strError)
    {
        strError = string.Empty;

        PdfWriter pdfWriter = new PdfWriter(OutputFile);
        PdfDocument pdfDocumentOut = new PdfDocument(pdfWriter);

        PdfReader pdfReader0 = new PdfReader(lststrInputFiles[0]);
        PdfDocument pdfDocument0 = new PdfDocument(pdfReader0);
        int iFirstPdfPageCount0 = pdfDocument0.GetNumberOfPages();
        pdfDocument0.CopyPagesTo(1, iFirstPdfPageCount0, pdfDocumentOut);
        iPageCount = pdfDocumentOut.GetNumberOfPages();

        for (int ii = 1; ii < lststrInputFiles.Count; ii++)
        {
            PdfReader pdfReader1 = new PdfReader(lststrInputFiles[ii]);
            PdfDocument pdfDocument1 = new PdfDocument(pdfReader1);
            int iFirstPdfPageCount1 = pdfDocument1.GetNumberOfPages();
            iPageCount += iFirstPdfPageCount1;
            pdfDocument1.CopyPagesTo(1, iFirstPdfPageCount1, pdfDocumentOut);
            int iFirstPdfPageCount00 = pdfDocumentOut.GetNumberOfPages();
        }

        pdfDocumentOut.Close();

        return true;
    }

I wrote this utility, it automatically generates the DSL code from a postgres database which you can then paste into dbdiagram.io/d website to get ER diagrams

Based o my previous answer, here is a more elegant solution with a custom class:

First define this custom class:

import UIKit
import Foundation

class ActivityIndicatorView
{
    var view: UIView!

var activityIndicator: UIActivityIndicatorView!

var title: String!

init(title: String, center: CGPoint, width: CGFloat = 200.0, height: CGFloat = 50.0)
{
    self.title = title

    let x = center.x - width/2.0
    let y = center.y - height/2.0

    self.view = UIView(frame: CGRect(x: x, y: y, width: width, height: height))
    self.view.backgroundColor = UIColor(red: 255.0/255.0, green: 204.0/255.0, blue: 51.0/255.0, alpha: 0.5)
    self.view.layer.cornerRadius = 10

    self.activityIndicator = UIActivityIndicatorView(frame: CGRect(x: 0, y: 0, width: 50, height: 50))
    self.activityIndicator.color = UIColor.blackColor()
    self.activityIndicator.hidesWhenStopped = false

    let titleLabel = UILabel(frame: CGRect(x: 60, y: 0, width: 200, height: 50))
    titleLabel.text = title
    titleLabel.textColor = UIColor.blackColor()

    self.view.addSubview(self.activityIndicator)
    self.view.addSubview(titleLabel)
}

func getViewActivityIndicator() -> UIView
{
    return self.view
}

func startAnimating()
{
    self.activityIndicator.startAnimating()
    UIApplication.sharedApplication().beginIgnoringInteractionEvents()
}

func stopAnimating()
{
    self.activityIndicator.stopAnimating()
    UIApplication.sharedApplication().endIgnoringInteractionEvents()

    self.view.removeFromSuperview()
}
//end
}

Now on your UIViewController class:

var activityIndicatorView: ActivityIndicatorView!

override func viewDidLoad()
{
    super.viewDidLoad()

    self.activityIndicatorView = ActivityIndicatorView(title: "Processing...", center: self.view.center)
    self.view.addSubview(self.activityIndicatorView.getViewActivityIndicator())

}

func doSomething()
{
    self.activityIndicatorView.startAnimating()
    UIApplication.sharedApplication().beginIgnoringInteractionEvents()

    //do something here that will taking time

    self.activityIndicatorView.stopAnimating()
}

Use saveAs on FileSaver.js github project.

FileSaver.js implements the saveAs() FileSaver interface in browsers that do not natively support it.

cleanText = strInputCode.replace(/<\/?[^>]+(>|$)/g, "");

Distilled from this website (web.achive).

This regex looks for <, an optional slash /, one or more characters that are not >, then either > or $ (the end of the line)

Examples:

'<div>Hello</div>' ==> 'Hello'
 ^^^^^     ^^^^^^
'Unterminated Tag <b' ==> 'Unterminated Tag '
                  ^^

But it is not bulletproof:

'If you are < 13 you cannot register' ==> 'If you are '
            ^^^^^^^^^^^^^^^^^^^^^^^^
'<div data="score > 42">Hello</div>' ==> ' 42">Hello'
 ^^^^^^^^^^^^^^^^^^          ^^^^^^

If someone is trying to break your application, this regex will not protect you. It should only be used if you already know the format of your input. As other knowledgable and mostly sane people have pointed out, to safely strip tags, you must use a parser.

If you do not have acccess to a convenient parser like the DOM, and you cannot trust your input to be in the right format, you may be better off using a package like sanitize-html, and also other sanitizers are available.

You can use

filter: brightness(0) invert(1);

html {_x000D_
  background: red;_x000D_
}_x000D_
p {_x000D_
  float: left;_x000D_
  max-width: 50%;_x000D_
  text-align: center;_x000D_
}_x000D_
img {_x000D_
  display: block;_x000D_
  max-width: 100%;_x000D_
}_x000D_
.filter {_x000D_
  -webkit-filter: brightness(0) invert(1);_x000D_
  filter: brightness(0) invert(1);_x000D_
}

<p>_x000D_
  Original:_x000D_
  <img src="http://i.stack.imgur.com/jO8jP.gif" />_x000D_
</p>_x000D_
<p>_x000D_
  Filter:_x000D_
  <img src="http://i.stack.imgur.com/jO8jP.gif" class="filter" />_x000D_
</p>

First, brightness(0) makes all image black, except transparent parts, which remain transparent.

Then, invert(1) makes the black parts white.

Using the above solutions, this will scroll to the bottom of your table (only if the table content is loaded first):

//Scroll to bottom of table
CGSize tableSize = myTableView.contentSize;
[myTableView setContentOffset:CGPointMake(0, tableSize.height)];

c is a double variable, but the value being assigned to it is an int value because it results from the division of two ints, which gives you "integer division" (dropping the remainder). So what happens in the line c=a/b is

1. a/b is evaluated, creating a temporary of type int
2. the value of the temporary is assigned to c after conversion to type double.

The value of a/b is determined without reference to its context (assignment to double).

Page 2 is in a new tab/window ? If it's this, use the code bellow :

try {

    String winHandleBefore = driver.getWindowHandle();

    for(String winHandle : driver.getWindowHandles()){
        driver.switchTo().window(winHandle);
        String act = driver.getCurrentUrl();
    }
    }catch(Exception e){
   System.out.println("fail");
    }

The solutions provided here can only be applied if the user defined types are used in table definitions only, and if the UDT columns are not indexed.

Some developers also have SP's and functions using UDT parameters, which is not covered either. (see comments on Robin's link and in the Connect entry)

The Connect entry from 2007 has finally been closed after 3 years:

Thank you for submitting this suggestion, but given its priority relative to the many other items in our queue, it is unlikely that we will actually complete it. As such, we are closing this suggestion as “won’t fix”.

I tried to solve a similiar problem ALTERing XML SCHEMA COLLECTIONS, and the steps seem to mostly apply to ALTER TYPE, too:

To drop a UDT, the following steps are necessary:

• If a table column references the UDT, it has to be converted to the underlying type
• If the table column has a default constraint, drop the default constraint
• If a procedure or function has UDT parameters, the procedure or function has to be dropped
• If there is an index on a UDT column, the index has to be dropped
• If the index is a primary key, all foreign keys have to be dropped
• If there are computed columns based on a UDT column, the computed columns have to be dropped
• If there are indexes on these computed columns, the indexes have to be dropped
• If there are schema-bound views, functions, or procedures based on tables containing UDT columns, these objects have to be dropped

Yes , Its easy to way we call the function inside the store procedure.

for e.g. create user define Age function and use in select query.

select dbo.GetRegAge(R.DateOfBirth, r.RegistrationDate) as Age,R.DateOfBirth,r.RegistrationDate from T_Registration R

Create an XML file named border.xml in the drawable folder and put the following code in it.

 <?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item> 
    <shape android:shape="rectangle">
      <solid android:color="#FF0000" /> 
    </shape>
  </item>   
    <item android:left="5dp" android:right="5dp"  android:top="5dp" >  
     <shape android:shape="rectangle"> 
      <solid android:color="#000000" />
    </shape>
   </item>    
 </layer-list> 

Then add a background to your linear layout like this:

         android:background="@drawable/border"

EDIT :

This XML was tested with a galaxy s running GingerBread 2.3.3 and ran perfectly as shown in image below:

ALSO

tested with galaxy s 3 running JellyBean 4.1.2 and ran perfectly as shown in image below :

Finally its works perfectly with all APIs

EDIT 2 :

It can also be done using a stroke to keep the background as transparent while still keeping a border except at the bottom with the following code.

<?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:left="0dp" android:right="0dp"  android:top="0dp"  
        android:bottom="-10dp"> 
    <shape android:shape="rectangle">
     <stroke android:width="10dp" android:color="#B22222" />
    </shape>
   </item>  
 </layer-list> 

hope this help .

System read-only variable %CD% keeps the path of the caller of the batch, not the batch file location.

You can get the name of the batch script itself as typed by the user with %0 (e.g. scripts\mybatch.bat). Parameter extensions can be applied to this so %~dp0 will return the Drive and Path to the batch script (e.g. W:\scripts\) and %~f0 will return the full pathname (e.g. W:\scripts\mybatch.cmd).

You can refer to other files in the same folder as the batch script by using this syntax:

CALL %0\..\SecondBatch.cmd

This can even be used in a subroutine, Echo %0 will give the call label but, echo "%~nx0" will give you the filename of the batch script.

When the %0 variable is expanded, the result is enclosed in quotation marks.

All markers in Google Android Maps Api v2 are clickable. You don't need to set any additional properties to your marker. What you need to do - is to register marker click callback to your googleMap and handle click within callback:

public class MarkerDemoActivity extends android.support.v4.app.FragmentActivity
    implements OnMarkerClickListener
{
    private Marker myMarker;    

    private void setUpMap()
    {
        .......
        googleMap.setOnMarkerClickListener(this);

        myMarker = googleMap.addMarker(new MarkerOptions()
                    .position(latLng)
                    .title("My Spot")
                    .snippet("This is my spot!")
                    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
        ......
    }

    @Override
    public boolean onMarkerClick(final Marker marker) {

        if (marker.equals(myMarker)) 
        {
            //handle click here
        }
    }
}

here is a good guide on google about marker customization

Try this instead:

String scheme = req.getScheme();             
String serverName = req.getServerName(); 
int serverPort = req.getServerPort();    
String uri = (String) req.getAttribute("javax.servlet.forward.request_uri");
String prmstr = (String) req.getAttribute("javax.servlet.forward.query_string");
String url = scheme + "://" +serverName + ":" + serverPort + uri + "?" + prmstr;

Note: You can't get HREF anchor from your url. Example, if you have url "toc.html#top" then you can get only "toc.html"

Note: req.getAttribute("javax.servlet.forward.request_uri") work only in JSP. if you run this in controller before JSP then result is null

You can use code for both variant:

public static String getCurrentUrl(HttpServletRequest req) {
    String url = getCurrentUrlWithoutParams(req);
    String prmstr = getCurrentUrlParams(req);
    url += "?" + prmstr;
    return url;
}

public static String getCurrentUrlParams(HttpServletRequest request) {
    return StringUtil.safeString(request.getQueryString());
}

public static String getCurrentUrlWithoutParams(HttpServletRequest request) {
    String uri = (String) request.getAttribute("javax.servlet.forward.request_uri");
    if (uri == null) {
        return request.getRequestURL().toString();
    }
    String scheme = request.getScheme();
    String serverName = request.getServerName();
    int serverPort = request.getServerPort();
    String url = scheme + "://" + serverName + ":" + serverPort + uri;
    return url;
}

If you have merged cells,

Sub OneCell()
    Sheets("Sheet2").range("B1:B3").value = Sheets("Sheet1").range("A1:A3").value
End Sub

that doesn't copy cells as they are, where previous code does copy exactly as they look like (merged).

Try the read shell builtin:

read -p "Continue (y/n)?" CONT
if [ "$CONT" = "y" ]; then
  echo "yaaa";
else
  echo "booo";
fi

To complement Jakub's answer, if you have access to the remote git server in ssh, you can go into the git remote directory and set:

user@remote$ git config receive.denyNonFastforwards false

Then go back to your local repo, try again to do your commit with --force:

user@local$ git push origin +master:master --force

And finally revert the server's setting in the original protected state:

user@remote$ git config receive.denyNonFastforwards true

I'd rather than ternary if-statements go with a switch-case. For example:

switch($result->vocation){
case 1:
    echo "Sorcerer";
    break;
case 2:
    echo "Druid";
    break;
case 3:
    echo "Paladin";
    break;
case 4:
    echo "Knight";
    break;
case 5:
    echo "Master Sorcerer";
    break;
case 6:
    echo "Elder Druid";
    break;
case 7:
    echo "Royal Paladin";
    break;
default:
    echo "Elite Knight";
    break;
}

Use a service to achieve this:

MyApp.app.service("xxxSvc", function () {

var _xxx = {};

return {
    getXxx: function () {
        return _xxx;
    },
    setXxx: function (value) {
        _xxx = value;
    }
};

});

Next, inject this service into both controllers.

In Controller1, you would need to set the shared xxx value with a call to the service: xxxSvc.setXxx(xxx)

Finally, in Controller2, add a $watch on this service's getXxx() function like so:

  $scope.$watch(function () { return xxxSvc.getXxx(); }, function (newValue, oldValue) {
        if (newValue != null) {
            //update Controller2's xxx value
            $scope.xxx= newValue;
        }
    }, true);

df$Gene <- as.factor(df$Gene)
do.call(rbind, lapply(split(df,df$Gene), function(x) {return(x[which.max(x$Value),])}))

Just using base R

If you have date object like

var date = new Date('2017/12/03');

then there is inbuilt method in javascript for getting date in milliseconds format which is valueOf()

date.valueOf(); //1512239400000 in milliseconds format

There is only one PNG format, but it supports 5 color types.

PNG-8 refers to palette variant, which supports only 256 colors, but is usually smaller in size. PNG-8 can be a GIF substitute.

PNG-24 refers to true color variant, which supports more colors, but might be bigger. PNG-24 can be used instead of JPEG, if lossless image format is needed.

Any modern web browser will support both variants.

For a lot of my projects, I prefer the lexicon-based WordNet lemmatizer over the more aggressive porter stemming.

http://wordnet.princeton.edu/links#PHP has a link to a PHP interface to the WN APIs.

Also note that most search engine spiders don't index CSS background images therefore the background images will be ignored and you won't be able to get any traffic from search engines (no SEO benefit in short).

Where as all images defined with tags are indexed (unless manually excluded) and can bring in traffic from search engines if their title/alt attributes and filenames are optimized properly (w.r.t some keyword).

As Kris mentions, you can use the $resource service to interact with the server, but I get the impression you are beginning your journey with Angular - I was there last week - so I recommend to start experimenting directly with the $http service. In this case you can call its get method.

If you have the following JSON

[{ "text":"learn angular", "done":true },
 { "text":"build an angular app", "done":false},
 { "text":"something", "done":false },
 { "text":"another todo", "done":true }]

You can load it like this

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

App.controller('TodoCtrl', function($scope, $http) {
  $http.get('todos.json')
       .then(function(res){
          $scope.todos = res.data;                
        });
});

The get method returns a promise object which first argument is a success callback and the second an error callback.

When you add $http as a parameter of a function Angular does it magic and injects the $http resource into your controller.

I've put some examples here
