An other way you can approach the matter:

import redis
conn = redis.Redis('localhost')

v={'class':'user','grants': 0, 'nome': 'Roberto', 'cognome': 'Brunialti'}

y=str(v)
print(y['nome']) #<=== this return an error as y is actually a string
conn.set('test',y)

z=eval(conn.get('test'))
print(z['nome']) #<=== this really works!

I did not test it for efficiency/speed.

Just stumbled upon this and thought I would suggest my solution. I typically like to use the built in functionality of assigning a range to an multi-dim array (I guess it's also the JS Programmer in me).

I frequently write code like this:

Sub arrayBuilder()

myarray = Range("A1:D4")

'unlike most VBA Arrays, this array doesn't need to be declared and will be automatically dimensioned

For i = 1 To UBound(myarray)

    For j = 1 To UBound(myarray, 2)

    Debug.Print (myarray(i, j))

    Next j

Next i

End Sub

Assigning ranges to variables is a very powerful way to manipulate data in VBA.

If you migrated to AndroidX you should add the dependency in graddle like this:

com.google.android.material:material:1.0.0-rc01

If you work in MS Visual Studio just do following

1. Put WSDL file and XSD file at the same folder.

2. Correct WSDL file like this YourSchemeFile.xsd

3. Use visual Studio using this great example How to generate service reference with only physical wsdl file

Notice that you have to put the path to your WSDL file manually. There is no way to use Open File dialog box out there.

This function will reorder your columns without losing data. Any omitted columns remain in the center of the data set:

def reorder_columns(columns, first_cols=[], last_cols=[], drop_cols=[]):
    columns = list(set(columns) - set(first_cols))
    columns = list(set(columns) - set(drop_cols))
    columns = list(set(columns) - set(last_cols))
    new_order = first_cols + columns + last_cols
    return new_order

Example usage:

my_list = ['first', 'second', 'third', 'fourth', 'fifth', 'sixth']
reorder_columns(my_list, first_cols=['fourth', 'third'], last_cols=['second'], drop_cols=['fifth'])

# Output:
['fourth', 'third', 'first', 'sixth', 'second']

To assign to your dataframe, use:

my_list = df.columns.tolist()
reordered_cols = reorder_columns(my_list, first_cols=['fourth', 'third'], last_cols=['second'], drop_cols=['fifth'])
df = df[reordered_cols]

INSERT INTO table 2
SELECT * FROM table1/view1

I have executed the code in my machine its working for IE and FF also.

function closeSelf(){
    // do something

    if(condition satisfied){
       alert("conditions satisfied, submiting the form.");
       document.forms['certform'].submit();
       window.close();
    }else{
       alert("conditions not satisfied, returning to form");    
    }
}


<form action="/system/wpacert" method="post" enctype="multipart/form-data" name="certform">
       <div>Certificate 1: <input type="file" name="cert1"/></div>
       <div>Certificate 2: <input type="file" name="cert2"/></div>
       <div>Certificate 3: <input type="file" name="cert3"/></div>

       // change the submit button to normal button
       <div><input type="button" value="Upload"  onclick="closeSelf();"/></div>
</form>

As of API 21, you could also use:

   ResourcesCompat.getDrawable(getResources(), R.drawable.name, null);

Instead of ContextCompat.getDrawable(context, android.R.drawable.ic_dialog_email)

func setTitleColor(_ color: UIColor?, 
               for state: UIControl.State)

Parameters:

color:
The color of the title to use for the specified state.

state:
The state that uses the specified color. The possible values are described in UIControl.State.

Sample:

let MyButton = UIButton()
MyButton.setTitle("Click Me..!", for: .normal)
MyButton.setTitleColor(.green, for: .normal)

You could use. mainAxisAlignment:MainAxisAlignment.center This will the material through the center in the column wise. `crossAxisAlignment: CrossAxisAlignment.center' This will align the items in the center in the row wise.

Container( alignment:Alignment.center, Child: Column () )

Simply use. Center ( Child: Column () ) or rap with Padding widget . And adjust the Padding such the the column children are in the center.

This will search all the related files in current and sub directories, calculating their line count separately as well as totally:

find . -name "*.wanted" | xargs wc -l

Take a look at Array.slice(begin, end)

const ar  = [1, 2, 3, 4, 5];

// slice from 1..3 - add 1 as the end index is not included

const ar2 = ar.slice(1, 3 + 1);

console.log(ar2);

You can also set onSubmit attribute's value in form tag. You can set its value using Javascript.

Something like this:

<form id="whatever" name="whatever" onSubmit="return xyz();">
    Here is your entire form
    <input type="submit">
</form>;

<script type=text/javascript>
function xyz() {
  document.getElementById('whatever').action = 'whatever you want'
}
</script>

Remember that onSubmit has higher priority than action attribute. So whenever you specify onSubmit value, that operation will be performed first and then the form will move to action.

I couldn't get Nitin Sawant's answer to work, but I was able to modify his code to work for me. Essentially I needed to use GetRuntimeFields instead of GetProperties. Here's what I ended up with:

public static class Extensions
{
    public static List<T> ToList<T>(this DataTable table) where T : new()
    {
        IList<FieldInfo> fields = typeof(T).GetRuntimeFields().ToList();
        List<T> result = new List<T>();
        if (row.Table.Columns.Contains(field.Name))
        {
            foreach (var row in table.Rows)
            {
                var item = CreateItemFromRow<T>((DataRow)row, fields);
                result.Add(item);
            }
        }

        return result;
    }

    private static T CreateItemFromRow<T>(DataRow row, IList<FieldInfo> fields) where T : new()
    {
        T item = new T();

        foreach (var field in fields)
        {
            if (row[field.Name] == DBNull.Value)
                field.SetValue(item, null);
            else
                field.SetValue(item, row[field.Name]);
        }
        return item;
    }
}

This way is much simple...

<form [formGroup]="form" (keyup.enter)="yourMethod(form.value)">

</form>

jQuery < 1.8

May I suggest that you use $.ajax() instead of $.post() as it's much more customizable.

If you are calling $.post(), e.g., like this:

$.post( url, data, success, dataType );

You could turn it into its $.ajax() equivalent:

$.ajax({
  type: 'POST',
  url: url,
  data: data,
  success: success,
  dataType: dataType,
  async:false
});

Please note the async:false at the end of the $.ajax() parameter object.

Here you have a full detail of the $.ajax() parameters: jQuery.ajax() – jQuery API Documentation.

jQuery >=1.8 "async:false" deprecation notice

jQuery >=1.8 won't block the UI during the http request, so we have to use a workaround to stop user interaction as long as the request is processed. For example:

• use a plugin e.g. BlockUI;
• manually add an overlay before calling $.ajax(), and then remove it when the AJAX .done() callback is called.

Please have a look at this answer for an example.

You can easily use xml (from the Python standard library) to convert to a pandas.DataFrame. Here's what I would do (when reading from a file replace xml_data with the name of your file or file object):

import pandas as pd
import xml.etree.ElementTree as ET
import io

def iter_docs(author):
    author_attr = author.attrib
    for doc in author.iter('document'):
        doc_dict = author_attr.copy()
        doc_dict.update(doc.attrib)
        doc_dict['data'] = doc.text
        yield doc_dict

xml_data = io.StringIO(u'''\

etree = ET.parse(xml_data) #create an ElementTree object 
doc_df = pd.DataFrame(list(iter_docs(etree.getroot())))

If there are multiple authors in your original document or the root of your XML is not an author, then I would add the following generator:

def iter_author(etree):
    for author in etree.iter('author'):
        for row in iter_docs(author):
            yield row

and change doc_df = pd.DataFrame(list(iter_docs(etree.getroot()))) to doc_df = pd.DataFrame(list(iter_author(etree)))

Have a look at the ElementTree tutorial provided in the xml library documentation.

Basically the answer from Jani Hartikainen is right! I upvoted his answer. What was missing on my system (based on Ubuntu 15.04) was to enable PDO Extension in my php.ini

extension=pdo.so
extension=pdo_mysql.so

restart the webserver (e.g. with "sudo service apache2 restart") -> every fine :-)

To find where your current active php.ini file is located you can use phpinfo() or some other hints from here: https://www.ostraining.com/blog/coding/phpini-file/

use as below:

<div id="getSessionStorage"></div>

For this to append anything use below code for reference:

$(document).ready(function () {
        var storageVal = sessionStorage.getItem("UserName");
        alert(storageVal);
        $("#getSessionStorage").append(storageVal);
     });

This will appear as below in html (assuming storageVal="Rishabh")

<div id="getSessionStorage">Rishabh</div>

There's the global attribute called hidden. But I'm green to all this and maybe there was a reason it wasn't mentioned yet?

var someCondition = true;_x000D_
_x000D_
if (someCondition == true){_x000D_
    document.getElementById('hidden div').hidden = false;_x000D_
}

<div id="hidden div" hidden>_x000D_
    stuff hidden by default_x000D_
</div>

https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/hidden

There is no standard way to do this. You need to use 3rd party tools such as ApexSQL Restore or SQL Virtual Restore. These tools don’t really read the backup file directly. They get SQL Server to “think” of backup files as if these were live databases.

If you don't want to import the calendar module, a simple two-step function can also be:

import datetime

def last_day_of_month(any_day):
    # this will never fail
    # get close to the end of the month for any day, and add 4 days 'over'
    next_month = any_day.replace(day=28) + datetime.timedelta(days=4)
    # subtract the number of remaining 'overage' days to get last day of current month, or said programattically said, the previous day of the first of next month
    return next_month - datetime.timedelta(days=next_month.day)

Outputs:

>>> for month in range(1, 13):
...     print last_day_of_month(datetime.date(2012, month, 1))
...
2012-01-31
2012-02-29
2012-03-31
2012-04-30
2012-05-31
2012-06-30
2012-07-31
2012-08-31
2012-09-30
2012-10-31
2012-11-30
2012-12-31

We can make class dynamic by using following syntax. In Angular 2 plus, you can do this in various ways:

[ngClass]="{'active': arrayData.length && arrayData[0]?.booleanProperty}"

[ngClass]="{'active': step}"

[ngClass]="step== 'step1'?'active':''"

[ngClass]="step? 'active' : ''"

If you want to stop tracking file without deleting the file from your local system, which I prefer for ignoring config/database.yml file. Simply try:

git rm --cached config/database.yml
# this will delete your file from git history but not from your local system.

now, add this file to .gitignore file and commit the changes. And from now on, any changes made to config/database.yml will not get tracked by git.

$ echo config/database.yml >> .gitignore

SELECT

Years later i had the same problem. My solution is the creation of a temporary batchfile and another instance of sqlplus:

In first SQL-Script:

:
set echo off
spool sqlsub_tmp.bat
prompt cd /D D:\some\dir
prompt sqlplus user/passwd@tnsname @second_script.sql
spool off
host sqlsub_tmp.bat
host del sqlsub_tmp.bat
:

Note that "second_script.sql" needs an "exit" statement at end if you want to return to the first one..

You should really use generics and the enhanced for loop for this:

Map<Integer, String> hm = new HashMap<>();
hm.put(0, "zero");
hm.put(1, "one");

for (Integer key : hm.keySet()) {
    System.out.println(key);
    System.out.println(hm.get(key));
}

http://ideone.com/sx3F0K

Or the entrySet() version:

Map<Integer, String> hm = new HashMap<>();
hm.put(0, "zero");
hm.put(1, "one");

for (Map.Entry<Integer, String> e : hm.entrySet()) {
    System.out.println(e.getKey());
    System.out.println(e.getValue());
}

You can try nvtop, which is similar to the widely-used htop tool but for NVIDIA GPUs. Here is a screenshot of nvtop of it in action.

global is a bit of a misnomer in Python, module_namespace would be more descriptive.

The fully qualified name of foo is file1.foo and the global statement is best shunned as there are usually better ways to accomplish what you want to do. (I can't tell what you want to do from your toy example.)

You can use a conditional expression:

x if x is not None else some_value

Example:

In [22]: x = None

In [23]: print x if x is not None else "foo"
foo

In [24]: x = "bar"

In [25]: print x if x is not None else "foo"
bar

In VS 2005/2008 you can use private accessor to test private member,but this way was disappear in later version of VS

# -*- coding: utf-8 -*- is a Python 2 thing. In Python 3+, the default encoding of source files is already UTF-8 and that line is useless.

See: Should I use encoding declaration in Python 3?

pyupgrade is a tool you can run on your code to remove those comments and other no-longer-useful leftovers from Python 2, like having all your classes inherit from object.

.btn is the best way, in modern website, it's not good while using anchor element without href so make the anchor tag to button is better.

java.time

The modern approach uses the java.time classes that supplanted the troublesome legacy date-time classes bundled with the earliest versions of Java.

The java.sql.Timestamp class is one of those legacy classes. No longer needed. Instead use Instant or other java.time classes directly with your database using JDBC 4.2 and later.

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = myResultSet.getObject( … , Instant.class ) ; 

If you must interoperate with an existing Timestamp, convert immediately into java.time via the new conversion methods added to the old classes.

Instant instant = myTimestamp.toInstant() ;

To adjust into another time zone, specify the time zone as a ZoneId object. Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter pseudo-zones such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "America/Montreal" ) ;

Apply to the Instant to produce a ZonedDateTime object.

ZonedDateTime zdt = instant.atZone( z ) ;

To generate a string for display to the user, search Stack Overflow for DateTimeFormatter to find many discussions and examples.

Your Question is really about going the other direction, from user data-entry to the date-time objects. Generally best to break your data-entry into two parts, a date and a time-of-day.

LocalDate ld = LocalDate.parse( dateInput , DateTimeFormatter.ofPattern( "M/d/uuuu" , Locale.US ) ) ;
LocalTime lt = LocalTime.parse( timeInput , DateTimeFormatter.ofPattern( "H:m a" , Locale.US ) ) ;

Your Question is not clear. Do you want to interpret the date and the time entered by the user to be in UTC? Or in another time zone?

If you meant UTC, create a OffsetDateTime with an offset using the constant for UTC, ZoneOffset.UTC.

OffsetDateTime odt = OffsetDateTime.of( ld , lt , ZoneOffset.UTC ) ;

If you meant another time zone, combine along with a time zone object, a ZoneId. But which time zone? You might detect a default time zone. Or, if critical, you must confirm with the user to be certain of their intention.

ZonedDateTime zdt = ZonedDateTime.of( ld , lt , z ) ;

To get a simpler object that is always in UTC by definition, extract an Instant.

Instant instant = odt.toInstant() ;

…or…

Instant instant = zdt.toInstant() ; 

Send to your database.

myPreparedStatement.setObject( … , instant ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

You have to wait for TypeScript 2.0 with async/await for ES5 support as it now supported only for TS to ES6 compilation.

You would be able to create delay function with async:

function delay(ms: number) {
    return new Promise( resolve => setTimeout(resolve, ms) );
}

And call it

await delay(300);

Please note, that you can use await only inside async function.

If you can't (let's say you are building nodejs application), just place your code in the anonymous async function. Here is an example:

    (async () => { 
        // Do something before delay
        console.log('before delay')

        await delay(1000);

        // Do something after
        console.log('after delay')
    })();

Example TS Application: https://github.com/v-andrew/ts-template

In OLD JS you have to use

setTimeout(YourFunctionName, Milliseconds);

or

setTimeout( () => { /*Your Code*/ }, Milliseconds );

However with every major browser supporting async/await it less useful.

Update: TypeScript 2.1 is here with async/await.

Just do not forget that you need Promise implementation when you compile to ES5, where Promise is not natively available.

PS

You have to export the function if you want to use it outside of the original file.

Use the shell globbing syntax:

grep pattern -r --include=\*.{cpp,h} rootdir

The syntax for --exclude is identical.

Note that the star is escaped with a backslash to prevent it from being expanded by the shell (quoting it, such as --include="*.{cpp,h}", would work just as well). Otherwise, if you had any files in the current working directory that matched the pattern, the command line would expand to something like grep pattern -r --include=foo.cpp --include=bar.h rootdir, which would only search files named foo.cpp and bar.h, which is quite likely not what you wanted.

Similar answer, but I just wanted to make it available for an easy/quick test.

var input = $("<input>")_x000D_
               .attr("name", "mydata").val("go Rafa!");_x000D_
_x000D_
$('#easy_test').append(input);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.3/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
_x000D_
<form id="easy_test">_x000D_
  _x000D_
</form>

I also faced this issue in phpMyAdmin. Using LOAD_DATA instead of LOAD solved the problem.

The columns were:

id,date,description,amount,payment_method 

with id as an AUTO_INCREMENT primary key. Records were like this one:

,2019-01-01,Car insurance for year 2019,321.00,bank

The table encoding was utf8_general_ci and the file was in utf-8 encoded.

LOAD also failed when setting manually a value for column id.

If you are happy with the xlsx format, try my GitHub project, EPPlus. It started with the source from ExcelPackage, but today it's a total rewrite. It supports ranges, cell styling, charts, shapes, pictures, named ranges, AutoFilter and a lot of other stuff.

Arriving late to the party but in our case we were getting this issue in Safari & iOS when using ES6 back tick instead of String() to type cast

This was giving 'invalid date' error

const dateString = '2011-11-18';
const dateObj = new Date(`${dateString}`); 

But this works

const dateObj = new Date(String(dateString)); 

Here's something you can try

DECLARE  @SqlStatement  NVARCHAR(MAX) = ''
       ,@result     XML
       ,@DatabaseName  VARCHAR(100)

SET @SqlStatement = '
                    SELECT @result = CONVERT(XML,

SELECT DISTINCT
    QUOTENAME(r.value('fn:local-name(.)', 'VARCHAR(200)')) AS ColumnName

ORDER BY ColumnName

This cannot be done in one statement. You will have to use 2 statements

DELETE FROM TB1 WHERE PersonID = '2';
DELETE FROM TB2 WHERE PersonID = '2';

Git v2.0 Release Notes

Backward compatibility notes

When git push [$there] does not say what to push, we have used the traditional "matching" semantics so far (all your branches were sent to the remote as long as there already are branches of the same name over there). In Git 2.0, the default is now the "simple" semantics, which pushes:

• only the current branch to the branch with the same name, and only when the current branch is set to integrate with that remote branch, if you are pushing to the same remote as you fetch from; or

• only the current branch to the branch with the same name, if you are pushing to a remote that is not where you usually fetch from.

You can use the configuration variable "push.default" to change this. If you are an old-timer who wants to keep using the "matching" semantics, you can set the variable to "matching", for example. Read the documentation for other possibilities.

When git add -u and git add -A are run inside a subdirectory without specifying which paths to add on the command line, they operate on the entire tree for consistency with git commit -a and other commands (these commands used to operate only on the current subdirectory). Say git add -u . or git add -A . if you want to limit the operation to the current directory.

git add <path> is the same as git add -A <path> now, so that git add dir/ will notice paths you removed from the directory and record the removal. In older versions of Git, git add <path> used to ignore removals. You can say git add --ignore-removal <path> to add only added or modified paths in <path>, if you really want to.

One of the common mistakes people do when change the image source is not waiting for image load to do afterward actions like maturing image size etc. You will need to use jQuery .load() method to do stuff after image load.

$('yourimageselector').attr('src', 'newsrc').load(function(){
    this.width;   // Note: $(this).width() will not work for in memory images

});

Arrays have a property .length that returns the number of elements.

var st =
    {
        "itema":{},
        "itemb":
        [
            {"id":"s01","cd":"c01","dd":"d01"},
            {"id":"s02","cd":"c02","dd":"d02"}
        ]
    };

st.itemb.length // 2

Python 2 only: (and python 2.7 supports `in` already)

you can use the has_key() method:

if dict.has_key('xyz')==1:
    #update the value for the key
else:
    pass

The only way I can think of doing it is by invoking a command line application that does the job for you and then screenscraping the output (like Linux's ps and Window's tasklist).

Unfortunately, that'll mean you'll have to write some parsing routines to read the data from both.

Process proc = Runtime.getRuntime().exec ("tasklist.exe");
InputStream procOutput = proc.getInputStream ();
if (0 == proc.waitFor ()) {
    // TODO scan the procOutput for your data
}

Updated for Angular 5

import { Directive, HostListener, Input } from '@angular/core';

@Directive({
  // tslint:disable-next-line:directive-selector
  selector : '[href]'
})
export class HrefDirective {
  @Input() public href: string | undefined;

  @HostListener('click', ['$event']) public onClick(event: Event): void {
    if (!this.href || this.href === '#' || (this.href && this.href.length === 0)) {
      event.preventDefault();
    }
  }
}

or you can use:

a {
    display: inline-block;
  }

Your code is correct. I tested:

r = requests.get("http://www.google.com")
print(r.content)

And it returned plenty of content. Check the url, try "http://www.google.com". Cheers!

Expanding on what Mark Elliot said earlier, the easiest way to get the size of a 2D array given that each array in the array of arrays is of the same size is:

array.length * array[0].length

(I just got this working, with my main issue being that I don't have a real internet hostname, so answering this question in case it helps someone)

You need to specify a hostname with HELO. Even so, you should get an error, so Postfix is probably not running.

Also, the => is not a command. The '.' on a single line without any text around it is what tells Postfix that the entry is complete. Here are the entries I used:

telnet localhost 25
(says connected)
EHLO howdy.com
(returns a bunch of 250 codes)
MAIL FROM: [email protected]
RCPT TO: (use a real email address you want to send to)
DATA (type whatever you want on muliple lines)
. (this on a single line tells Postfix that the DATA is complete)

You should get a response like:

250 2.0.0 Ok: queued as 6E414C4643A

The email will probably end up in a junk folder. If it is not showing up, then you probably need to setup the 'Postfix on hosts without a real Internet hostname'. Here is the breakdown on how I completed that step on my Ubuntu box:

sudo vim /etc/postfix/main.cf
smtp_generic_maps = hash:/etc/postfix/generic (add this line somewhere)
(edit or create the file 'generic' if it doesn't exist)
sudo vim /etc/postfix/generic
(add these lines, I don't think it matters what names you use, at least to test)
[email protected]             [email protected]
[email protected]             [email protected]
@localdomain.local                [email protected]
then run:
postmap /etc/postfix/generic (this needs to be run whenever you change the 
generic file)

Happy Trails

Here's a modified version of Hors answer, works slightly better for my case, as it strips out the base directory that is passed as it goes, and has a recursive switch that can be set to false which is also handy. Plus to make the output more readable, I've separated the file and subdirectory files, so the files are added first then the subdirectory files (see result for what I mean.)

I tried a few other methods and suggestions around and this is what I ended up with. I had another working method already that was very similar, but seemed to fail where there was a subdirectory with no files but that subdirectory had a subsubdirectory with files, it didn't scan the subsubdirectory for files - so some answers may need to be tested for that case.)... anyways thought I'd post my version here too in case someone is looking...

function get_filelist_as_array($dir, $recursive = true, $basedir = '', $include_dirs = false) {
    if ($dir == '') {return array();} else {$results = array(); $subresults = array();}
    if (!is_dir($dir)) {$dir = dirname($dir);} // so a files path can be sent
    if ($basedir == '') {$basedir = realpath($dir).DIRECTORY_SEPARATOR;}

    $files = scandir($dir);
    foreach ($files as $key => $value){
        if ( ($value != '.') && ($value != '..') ) {
            $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
            if (is_dir($path)) {
                // optionally include directories in file list
                if ($include_dirs) {$subresults[] = str_replace($basedir, '', $path);}
                // optionally get file list for all subdirectories
                if ($recursive) {
                    $subdirresults = get_filelist_as_array($path, $recursive, $basedir, $include_dirs);
                    $results = array_merge($results, $subdirresults);
                }
            } else {
                // strip basedir and add to subarray to separate file list
                $subresults[] = str_replace($basedir, '', $path);
            }
        }
    }
    // merge the subarray to give the list of files then subdirectory files
    if (count($subresults) > 0) {$results = array_merge($subresults, $results);}
    return $results;
}

I suppose one thing to be careful of it not to pass a $basedir value to this function when calling it... mostly just pass the $dir (or passing a filepath will work now too) and optionally $recursive as false if and as needed. The result:

[0] => demo-image.png
[1] => filelist.php
[2] => tile.png
[3] => 2015\header.png
[4] => 2015\08\background.jpg

Enjoy! Okay, back to the program I'm actually using this in...

UPDATE Added extra argument for including directories in the file list or not (remembering other arguments will need to be passed to use this.) eg.

$results = get_filelist_as_array($dir, true, '', true);

There is a setting inside the PDF file that turns on the allow saving with data bit. However, it requires that you have a copy of Adobe Acrobat installed to change the bit.

The only other option is to print it to a PDF print driver which would save the data merged with the pdf file.

UPDATE: The relevant information from adobe is at: http://www.adobeforums.com/webx?13@@.3bbb313f/7

i found following code working for ckeditor 5

ClassicEditor
    .create( document.querySelector( '#editor' ) )
    .then( editor => {
        editor.model.document.on( 'change:data', () => {
            editorData = editor.getData();
        } );
    } )
    .catch( error => {
        console.error( error );
    } );

Use CSS :

input[type=submit] {

background:url("BUTTON1.jpg");

}

For HTML :

<input type="submit" value="Login" style="background:url("BUTTON1.jpg");">

I noticed that this question was not marked as answered after 2 years - I think the closest answer is Richards, but it can be simplified quite a lot to this:

list1.Concat(list2)
    .ToLookup(p => p.Name)
    .Select(g => g.Aggregate((p1, p2) => new Person 
    {
        Name = p1.Name,
        Value = p1.Value, 
        Change = p2.Value - p1.Value 
    }));

Although this won't error in the case where you have duplicate names in either set.

Some other answers have suggested using unioning - this is definitely not the way to go as it will only get you a distinct list, without doing the combining.

There are several tools for converting Matlab to Python code.

The only one that's seen recent activity (last commit from June 2018) is Small Matlab to Python compiler (also developed here: SMOP@chiselapp).

Other options include:

• LiberMate: translate from Matlab to Python and SciPy (Requires Python 2, last update 4 years ago).
• OMPC: Matlab to Python (a bit outdated).

Also, for those interested in an interface between the two languages and not conversion:

• pymatlab: communicate from Python by sending data to the MATLAB workspace, operating on them with scripts and pulling back the resulting data.
• Python-Matlab wormholes: both directions of interaction supported.
• Python-Matlab bridge: use Matlab from within Python, offers matlab_magic for iPython, to execute normal matlab code from within ipython.
• PyMat: Control Matlab session from Python.
• pymat2: continuation of the seemingly abandoned PyMat.
• mlabwrap, mlabwrap-purepy: make Matlab look like Python library (based on PyMat).
• oct2py: run GNU Octave commands from within Python.
• pymex: Embeds the Python Interpreter in Matlab, also on File Exchange.
• matpy: Access MATLAB in various ways: create variables, access .mat files, direct interface to MATLAB engine (requires MATLAB be installed).
• MatPy: Python package for numerical linear algebra and plotting with a MatLab-like interface.

Btw might be helpful to look here for other migration tips:

• http://bci2000.org/downloads/BCPy2000/Migration.html

On a different note, though I'm not a fortran fan at all, for people who might find it useful there is:

• matlab2fortran

The most compact version:

<input type="submit" onclick="return confirm('Are you sure?')" />

The key thing to note is the return

-

Because there are many ways to skin a cat, here is another alternate method:

HTML:

<input type="submit" onclick="clicked(event)" />

Javascript:

<script>
function clicked(e)
{
    if(!confirm('Are you sure?')) {
        e.preventDefault();
    }
}
</script>

All functions in Java are virtual by default.

You have to go out of your way to write non-virtual functions by adding the "final" keyword.

This is the opposite of the C++/C# default. Class functions are non-virtual by default; you make them so by adding the "virtual" modifier.

The following code gives you the answer. It essentially implements MAX(COUNT(*)) by using ALL. It has the advantage that it uses very basic commands and operations.

SELECT yr, COUNT(title)
FROM actor
JOIN casting ON actor.id = casting.actorid
JOIN movie ON casting.movieid = movie.id
WHERE name = 'John Travolta'
GROUP BY yr HAVING COUNT(title) >= ALL
  (SELECT COUNT(title)
   FROM actor
   JOIN casting ON actor.id = casting.actorid
   JOIN movie ON casting.movieid = movie.id
   WHERE name = 'John Travolta'
   GROUP BY yr)

For my Win7

Paradox was in being java.exe and javaw.exe in System32 folder. Opening that folder I couldn't see them but using search in Start menu I get links to those files, removed them. Next searsh gave me links to files from JAVA_HOME

adding HTTP headers using urllib2:

from the docs:

import urllib2
req = urllib2.Request('http://www.example.com/')
req.add_header('Referer', 'http://www.python.org/')
resp = urllib2.urlopen(req)
content = resp.read()

In addition to grants, you can try creating synonyms. It will avoid the need for specifying the table owner schema every time.

From the connecting schema:

CREATE SYNONYM pi_int FOR pct.pi_int;

Then you can query pi_int as:

SELECT * FROM pi_int;

$rootScope.$on( "$routeChangeStart", function(event, next, current) {
  //..do something
  //event.stopPropagation();  //if you don't want event to bubble up 
});

File file = new File("src/test/resources/validation.txt");
DiskFileItem fileItem = new DiskFileItem("file", "text/plain", false, file.getName(), (int) file.length() , file.getParentFile());
fileItem.getOutputStream();
MultipartFile multipartFile = new CommonsMultipartFile(fileItem);

You need the

fileItem.getOutputStream();

because it will throw NPE otherwise.

Use the gcc compiler. This assumes that you have the developer tools installed.

The problem lies on your proxy. Because the location provider of your install package creates its own certificate and does not buy a verified one from an accepted authority, your proxy does not allow access to the targeted host. I assume that you bypass the proxy when using the Chrome Browser. So there is no checking.

There are some solutions to this problem. But all imply that you trust the package provider.

Possible solutions:

1. As mentioned in other answers you can make an http:// access which may bypass your proxy. That's a bit dangerous, because the man in the middle can inject malware into you downloads.
2. The wget suggests you to use a flag --no-check-certificate. This will add a proxy directive to your request. The proxy, if it understands the directive, does not check if the servers certificate is verified by an authority and passes the request. Perhaps there is a config with npm that does the same as the wget flag.
3. You configure your proxy to accept CA npm. I don't know your proxy, so I can't give you a hint.

As this code shows (see the dissambled MSIL in the comments), the C# 3 compiler makes no distinction between i++ and ++i in a for loop. If the value of i++ or ++i were being taken, there would definitely be a difference (this was compiled in Visutal Studio 2008 / Release Build):

You can combine multiple selectors with a comma:

$('#Create .myClass,#Edit .myClass').plugin({options here});

Or if you're going to have a bunch of them, you could add a class to all your form elements and then search within that class. This doesn't get you the supposed speed savings of restricting the search, but I honestly wouldn't worry too much about that if I were you. Browsers do a lot of fancy things to optimize common operations behind your back -- the simple class selector might be faster.

The simplest and the most efficient way is to use an uber plugin like this:

          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <finalName>uber-${project.artifactId}-${project.version}</finalName>
            </configuration>
        </plugin>

You will have de-normalized all in one JAR file.

You can achieve this using simple css as shown in below example

button {_x000D_
    overflow: visible;_x000D_
    width: auto;_x000D_

    padding: 0;_x000D_
    border: none;_x000D_

I was able to get the list mapping to work with just using @SerializedName for all fields.. no logic around Type was necessary.

Running the code - in step #4 below - through the debugger, I am able to observe that the List<ContentImage> mGalleryImages object populated with the JSON data

Here's an example:

1. The JSON

   {
    "name": "Some House",
    "gallery": [
      {
        "description": "Nice 300sqft. den.jpg",
        "photo_url": "image/den.jpg"
      },
      {
        "description": "Floor Plan",
        "photo_url": "image/floor_plan.jpg"
      }
    ]
  }

2. Java class with the List

public class FocusArea {

    @SerializedName("name")
    private String mName;

    @SerializedName("gallery")
    private List<ContentImage> mGalleryImages;
}

3. Java class for the List items

public class ContentImage {

    @SerializedName("description")
    private String mDescription;

    @SerializedName("photo_url")
    private String mPhotoUrl;

    // getters/setters ..
}

4. The Java code that processes the JSON

    for (String key : focusAreaKeys) {

        JsonElement sectionElement = sectionsJsonObject.get(key);
        FocusArea focusArea = gson.fromJson(sectionElement, FocusArea.class);
    }

Jython: Python for the Java Platform - http://www.jython.org/index.html

You can easily call python functions from Java code with Jython. That is as long as your python code itself runs under jython, i.e. doesn't use some c-extensions that aren't supported.

If that works for you, it's certainly the simplest solution you can get. Otherwise you can use org.python.util.PythonInterpreter from the new Java6 interpreter support.

A simple example from the top of my head - but should work I hope: (no error checking done for brevity)

PythonInterpreter interpreter = new PythonInterpreter();
interpreter.exec("import sys\nsys.path.append('pathToModules if they are not there by default')\nimport yourModule");
// execute a function that takes a string and returns a string
PyObject someFunc = interpreter.get("funcName");
PyObject result = someFunc.__call__(new PyString("Test!"));
String realResult = (String) result.__tojava__(String.class);

PHP's string length is limited by the way strings are represented in PHP; memory does not have anything to do with it.

According to phpinternalsbook.com, strings are stored in struct { char *val; int len; } and since the maximum size of an int in C is 4 bytes, this effectively limits the maximum string size to 2GB.

I had the same error for the MediaStream. The solution is set a stream to the srcObject.

From the docs:

Important: If you still have code that relies on createObjectURL() to attach streams to media elements, you need to update your code to simply set srcObject to the MediaStream directly.

does not work if numberOfLines > 1 What i did made a condition like this-

if(lblRecLocation.text.length > 100)
    lblRecLocation.font = [UIFont fontWithName:@"app_font_name" size:10];

There are already a lot of answers and they are all correct. In case you want to use the dispatch_after you should be looking for the snippet which is included inside the Code Snippet Library at the right bottom (where you can select the UI elements).

So you just need to call this snippet by writing dispatch in code:

This worked for me, found it long time ago somewhere.

Usage:

MySortableCollection.Sort(x => x, System.ComponentModel.ListSortDirection.Ascending);

An issue with the answer from Michal Foksa is that it adds the query parameters first, and then expands the path variables. If query parameter contains parenthesis, e.g. {foobar}, this will cause an exception.

The safe way is to expand the path variables first, and then add the query parameters:

String url = "http://test.com/Services/rest/{id}/Identifier";
Map<String, String> params = new HashMap<String, String>();
params.put("id", "1234");
URI uri = UriComponentsBuilder.fromUriString(url)
        .buildAndExpand(params)
        .toUri();
uri = UriComponentsBuilder
        .fromUri(uri)
        .queryParam("name", "myName")
        .build()
        .toUri();
restTemplate.exchange(uri , HttpMethod.PUT, requestEntity, class_p);

If refs/heads/master can be fast-forwarded to refs/remotes/foo/master, the output of

git merge-base refs/heads/master refs/remotes/foo/master

should return the SHA1 id that refs/heads/master points to. With this, you can put together a script that automatically updates all local branches that have had no diverting commits applied to them.

This little shell script (I called it git-can-ff) illustrates how it can be done.

#!/bin/sh

set -x

usage() {
    echo "usage: $(basename $0) <from-ref> <to-ref>" >&2
    exit 2
}

[ $# -ne 2 ] && usage

FROM_REF=$1
TO_REF=$2

FROM_HASH=$(git show-ref --hash $FROM_REF)
TO_HASH=$(git show-ref --hash $TO_REF)
BASE_HASH=$(git merge-base $FROM_REF $TO_REF)

if [ "$BASE_HASH" = "$FROM_HASH" -o \
     "$BASE_HASH" = "$FROM_REF" ]; then
    exit 0
else
    exit 1
fi

instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0; once your window has scrolled pass a certain height:

jQuery

  $(window).scroll(function(){
      if ($(this).scrollTop() > 135) {
          $('#task_flyout').addClass('fixed');
      } else {
          $('#task_flyout').removeClass('fixed');
      }
  });

css

.fixed {position:fixed; top:0; left:0;}

Example

give width as 0dp to make sure its size is exactly as per its weight this will make sure that even if content of child views get bigger, they'll still be limited to exactly half(according to is weight)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:weightSum="1"
     >

    <Button
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:text="click me"
    android:layout_weight="0.5"/>


    <TextView
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:text="Hello World"
    android:layout_weight="0.5"/>
  </LinearLayout>

I stop at three parameters as a general rule of thumb. Any more and it's time to pass an array of parameters or a configuration object instead, which also allows for future parameters to be added without changing the API.

If you are using ajax, you may want to get updated value of select right after the selection.

//Part 1

$(".element").select2(/*Your code*/)    

//Part 2 - continued 

$(".element").on("select2:select", function (e) { 
  var select_val = $(e.currentTarget).val();
  console.log(select_val)
});

One can replace unicode with u''.__class__ to handle the missing unicode class in Python 3. For both Python 2 and 3, you can use the construct

isinstance(unicode_or_str, u''.__class__)

or

type(unicode_or_str) == type(u'')

Depending on your further processing, consider the different outcome:

Python 3

>>> isinstance('text', u''.__class__)
True
>>> isinstance(u'text', u''.__class__)
True

Python 2

>>> isinstance(u'text', u''.__class__)
True
>>> isinstance('text', u''.__class__)
False

PEP-8 is the official python coding standard. It contains a section on docstrings, which refers to PEP-257 -- a complete specification for docstrings.

Perhaps you need to specify a top value in your css rule set, so that it will know what value to animate from.

onActivityCreated() - Deprecated

onActivityCreated() is now deprecated as Fragments Version 1.3.0-alpha02

The onActivityCreated() method is now deprecated. Code touching the fragment's view should be done in onViewCreated() (which is called immediately before onActivityCreated()) and other initialization code should be in onCreate(). To receive a callback specifically when the activity's onCreate() is complete, a LifeCycleObserver should be registered on the activity's Lifecycle in onAttach(), and removed once the onCreate() callback is received.

Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).

You need to do a deep equals.

From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.

Object.extend(Object, {
   deepEquals: function(o1, o2) {
     var k1 = Object.keys(o1).sort();
     var k2 = Object.keys(o2).sort();
     if (k1.length != k2.length) return false;
     return k1.zip(k2, function(keyPair) {
       if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
         return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
       } else {
         return o1[keyPair[0]] == o2[keyPair[1]];
       }
     }).all();
   }
});

Usage:

var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);

if (Object.deepEquals(anObj, anotherObj))

Here's a method you can use to rotate an image in C#:

/// <summary>
/// method to rotate an image either clockwise or counter-clockwise
/// </summary>
/// <param name="img">the image to be rotated</param>
/// <param name="rotationAngle">the angle (in degrees).
/// NOTE: 
/// Positive values will rotate clockwise
/// negative values will rotate counter-clockwise
/// </param>
/// <returns></returns>
public static Image RotateImage(Image img, float rotationAngle)
{
    //create an empty Bitmap image
    Bitmap bmp = new Bitmap(img.Width, img.Height);

    //turn the Bitmap into a Graphics object
    Graphics gfx = Graphics.FromImage(bmp);

    //now we set the rotation point to the center of our image
    gfx.TranslateTransform((float)bmp.Width / 2, (float)bmp.Height / 2);

    //now rotate the image
    gfx.RotateTransform(rotationAngle);

    gfx.TranslateTransform(-(float)bmp.Width / 2, -(float)bmp.Height / 2);

    //set the InterpolationMode to HighQualityBicubic so to ensure a high
    //quality image once it is transformed to the specified size
    gfx.InterpolationMode = InterpolationMode.HighQualityBicubic;

    //now draw our new image onto the graphics object
    gfx.DrawImage(img, new Point(0, 0));

    //dispose of our Graphics object
    gfx.Dispose();

    //return the image
    return bmp;
}

You can simply download the library which you want to include and copy it to libs folder of your project. Then select that file (in my case it was android-support-v4 library) right click on it and select "Add as Library"

In your 'head' section, add this code:

<style>
input[type='text'] { font-size: 24px; }
</style>

Or you can only add the:

input[type='text'] { font-size: 24px; }

to a CSS file which can later be included.

You can also change the font face by using the CSS property: font-family

font-family: monospace;

So you can have a CSS code like this:

input[type='text'] { font-size: 24px; font-family: monospace; }

You can find further help at the W3Schools website.

I suggest you to have a look at the CSS3 specification. With CSS3 you can also load a font from the web instead of having the limitation to use only the most common fonts or tell the user to download the font you're using.

I had to do a Clean Up and elect to "Break Locks" for it to work for me.

I think you've just made up shorthand syntax for the border: property there =)

Try simply:

border-right: 1px solid #000;
border-left: 1px solid #000;

or

<button (click)="removeAt(element.bookId)" (click)="openDeleteDialog()"> Click Here</button>

For everyone coming to this thread with fractional seconds in your timestamp use:

to_timestamp('2018-11-03 12:35:20.419000', 'YYYY-MM-DD HH24:MI:SS.FF')

As stated in the other answers use event.preventDefault() to prevent form submitting.

To check the form before I wrote a little jQuery function you may use (note that the element needs an ID!)

(function( $ ){
    $.fn.isValid = function() {
        return document.getElementById(this[0].id).checkValidity();
    };
})( jQuery );

example usage

 $('#submitBtn').click( function(e){

        if ($('#registerForm').isValid()){
            // do the request
        } else {
            e.preventDefault();
        }
    });

I had to unistall the Workstation Components and SSMS Tools Pack (SSMS Tools Pack is an add-in for Microsoft SQL Server Management Studio (SSMS) including SSMS Express.) Installation of SQL 2008 is now proceeding as it should.

To use requests (or any other blocking libraries) with asyncio, you can use BaseEventLoop.run_in_executor to run a function in another thread and yield from it to get the result. For example:

import asyncio
import requests

@asyncio.coroutine
def main():
    loop = asyncio.get_event_loop()
    future1 = loop.run_in_executor(None, requests.get, 'http://www.google.com')
    future2 = loop.run_in_executor(None, requests.get, 'http://www.google.co.uk')
    response1 = yield from future1
    response2 = yield from future2
    print(response1.text)
    print(response2.text)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

This will get both responses in parallel.

With python 3.5 you can use the new await/async syntax:

import asyncio
import requests

async def main():
    loop = asyncio.get_event_loop()
    future1 = loop.run_in_executor(None, requests.get, 'http://www.google.com')
    future2 = loop.run_in_executor(None, requests.get, 'http://www.google.co.uk')
    response1 = await future1
    response2 = await future2
    print(response1.text)
    print(response2.text)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

See PEP0492 for more.

Somehow all these solutions didn't work for me. There is clearly an IE bug in flex-direction:column.

I only got it working after removing flex-direction:

flex-wrap: wrap;
align-items: center;
align-content: center;

js> s = "http://www.example.com/string with + and ? and & and spaces";
http://www.example.com/string with + and ? and & and spaces
js> encodeURI(s)
http://www.example.com/string%20with%20+%20and%20?%20and%20&%20and%20spaces
js> encodeURIComponent(s)
http%3A%2F%2Fwww.example.com%2Fstring%20with%20%2B%20and%20%3F%20and%20%26%20and%20spaces

Looks like encodeURI produces a "safe" URI by encoding spaces and some other (e.g. nonprintable) characters, whereas encodeURIComponent additionally encodes the colon and slash and plus characters, and is meant to be used in query strings. The encoding of + and ? and & is of particular importance here, as these are special chars in query strings.

You can stablish specific toolbar for div

div::-webkit-scrollbar {
width: 12px;
}

div::-webkit-scrollbar-track {
-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
border-radius: 10px;
}

If you want to change the card background color, use:

app:cardBackgroundColor="@somecolor"

like this:

<android.support.v7.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:cardBackgroundColor="@color/white">

</android.support.v7.widget.CardView>

Edit: As pointed by @imposible, you need to include

Answer from 2020 year :

dependencies {
    implementation "androidx.core:core-ktx:1.2.0"
}

and cal it simply in your code

view.updateLayoutParams<ViewGroup.MarginLayoutParams> {
   setMargins(5)
}

You can save an image as 'png' and use the python imaging library (PIL) to convert this file to 'jpg':

import Image
import matplotlib.pyplot as plt

plt.plot(range(10))
plt.savefig('testplot.png')
Image.open('testplot.png').save('testplot.jpg','JPEG')

Responsive text alignment has been added in Bootstrap V4:

https://getbootstrap.com/docs/4.0/utilities/text/#text-alignment

For left, right, and center alignment, responsive classes are available that use the same viewport width breakpoints as the grid system.

<p class="text-sm-left">Left aligned text on viewports sized SM (small) or wider.</p>

Use this code in your form.it will handle multiple clicks.

<script type="text/javascript">
    $(document).ready(function() {
        $("form").submit(function() {
            $(this).submit(function() {
                return false;
            });
            return true;
        });     
    }); 
</script>

it will work for sure.

Your code, as written, works. You’re probably trying to achieve something unrelated, but similar:

std::string c = "hello" + "world";

This doesn’t work because for C++ this seems like you’re trying to add two char pointers. Instead, you need to convert at least one of the char* literals to a std::string. Either you can do what you’ve already posted in the question (as I said, this code will work) or you do the following:

std::string c = std::string("hello") + "world";

In oracle-based products you may use the following statement:

update table set interfaceID=RowNum where condition;

401 means "Unauthorized", so there must be something with your credentials.

I think that java URL does not support the syntax you are showing. You could use an Authenticator instead.

Authenticator.setDefault(new Authenticator() {

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {          
        return new PasswordAuthentication(login, password.toCharArray());
    }
});

and then simply invoking the regular url, without the credentials.

The other option is to provide the credentials in a Header:

String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);

PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.

If anyone is still looking for the answer, i've solved it like so:

$("#photos").on("hide",function(){
    var leg=$('.videoPlayer').attr("src");
    $('.videoPlayer').attr("src",leg);
});

Where #photos is the ID of the modal and .videoPlayer is the class of the iframe. Basically it refreshes the src attribute (and stops playing the video). So,

    $('#myStopClickButton').click(function(){
      $('.yvideo').each(function(){
        var el_src = $(this).attr("src");
        $(this).attr("src",el_src);
      });
    });

should do the trick.

It is entirely dependent on how your data is sorted to begin with. If you think it will be pseudo-random then your best bet is to either pick a random selection or choose the middle.

This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.

Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.

In this case I'd ask why you're including both cstdlib and stdlib.h; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib puts them in the namespace std in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!

Anyway, your use of using namespace std (which I would recommend against, in future) means that std::system from cstdlib now conflicts with system from stdlib.h. I can't explain what's going on with std::cout and std::cin.

Try removing #include <stdlib.h> and see what happens.

If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.

Setting selected option is very simple in laravel form :

{{ Form::select('number', [0, 1, 2], 2) }}

Output will be :

<select name="number">
  <option value="0">0</option>
  <option value="1">1</option>
  <option value="2" selected="selected">2</option>
</select>

It should be 236 bytes. There is no restriction on the size of the alert text as far as I know, but only the total payload size. So considering if the payload is minimal and only contains the alert information, it should look like:

{"aps":{"alert":""}}

That takes up 20 characters (20 bytes), leaving 236 bytes to put inside the alert string. With ASCII that will be 236 characters, and could be lesser with UTF8 and UTF16.

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

Is there use case you can provide?

If you ever have the need for creating some dynamic sql it is appropriate to use sysname as data type for variables holding table names, column names and server names.

This works:

$category = $catrep->createQueryBuilder('cc')
        ->select('cc.categoryid')
        ->where('cc.contenttype = :type')
        ->setParameter('type', 'blogarticle')
        ->distinct()
        ->getQuery();

$categories = $category->getResult();

Edit for Symfony 3 & 4.

You should use ->groupBy('cc.categoryid') instead of ->distinct()

In your version rand() % 10000 will yield an integer between 0 and 9999. Since RAND_MAX may be as little as 32767, and since this is not exactly divisible by 10000 and not large relative to 10000, there will be significant bias in the 'randomness' of the result, moreover, the maximum value will be 0.9999, not 1.0, and you have unnecessarily restricted your values to four decimal places.

It is simple arithmetic, a random number divided by the maximum possible random number will yield a number from 0 to 1 inclusive, while utilising the full resolution and distribution of the RNG

double r2()
{
    return (double)rand() / (double)RAND_MAX ;
}

Use (double)rand() / (double)((unsigned)RAND_MAX + 1) if exclusion of 1.0 was intentional.

I used String and I converted initially the int to String.Then I used the reverse method. I found the reverse of the number in String and then I converted the string back to int. Here is the program.

import java.util.*;

public class Panathinaikos {
    public static void my_try()
    {
        Scanner input = new Scanner(System.in);
        System.out.println("Enter the number you want to be reversed");
        int number = input.nextInt();
        String sReverse = Integer.toString(number);
        String reverse = new StringBuffer(sReverse).reverse().toString();
        int Reversed = Integer.parseInt(reverse);
        System.out.print("The number " + number+ " reversed is " + Reversed);
    }
}

Try from tensorflow.python import keras

with this, you can easily change keras dependent code to tensorflow in one line change.

You can also try from tensorflow.contrib import keras. This works on tensorflow 1.3

Edited: for tensorflow 1.10 and above you can use import tensorflow.keras as keras to get keras in tensorflow.

The following bash script extracts all zip files in the current directory into new dirs with the filename of the zip file, i.e.:

The following files:

myfile1.zip
myfile2.zip 

Will be extracted to:

./myfile1/files...
./myfile2/files...

Shell script:

#!/bin/sh
for zip in *.zip
do
  dirname=`echo $zip | sed 's/\.zip$//'`
  if mkdir "$dirname"
  then
    if cd "$dirname"
    then
      unzip ../"$zip"
      cd ..
      # rm -f $zip # Uncomment to delete the original zip file
    else
      echo "Could not unpack $zip - cd failed"
    fi
  else
    echo "Could not unpack $zip - mkdir failed"
  fi
done

The .encode method gets applied to a Unicode string to make a byte-string; but you're calling it on a byte-string instead... the wrong way 'round! Look at the codecs module in the standard library and codecs.open in particular for better general solutions for reading UTF-8 encoded text files. However, for the csv module in particular, you need to pass in utf-8 data, and that's what you're already getting, so your code can be much simpler:

import csv

def unicode_csv_reader(utf8_data, dialect=csv.excel, **kwargs):
    csv_reader = csv.reader(utf8_data, dialect=dialect, **kwargs)
    for row in csv_reader:
        yield [unicode(cell, 'utf-8') for cell in row]

filename = 'da.csv'
reader = unicode_csv_reader(open(filename))
for field1, field2, field3 in reader:
  print field1, field2, field3 

PS: if it turns out that your input data is NOT in utf-8, but e.g. in ISO-8859-1, then you do need a "transcoding" (if you're keen on using utf-8 at the csv module level), of the form line.decode('whateverweirdcodec').encode('utf-8') -- but probably you can just use the name of your existing encoding in the yield line in my code above, instead of 'utf-8', as csv is actually going to be just fine with ISO-8859-* encoded bytestrings.

git checkout master should do the trick. To go back two versions, you could say something like git checkout HEAD~2, but better to create a temporary branch based on that time, so git checkout -b temp_branch HEAD~2

Yes. Pass gcc the -E option. This will output preprocessed source code.

Text nodes cannot have margins or any other style applied to them, so anything you need style applied to must be in an element. If you want some of the text inside of your element to be styled differently, wrap it in a span or div, for example.

Add the following line to the beginning script1.py

#!/usr/bin/env python

and then make the script executable:

$ chmod +x script1.py

If the script resides in a directory that appears in your PATH variable, you can simply type

$ script1.py

Otherwise, you'll need to provide the full path (either absolute or relative). This includes the current working directory, which should not be in your PATH.

$ ./script1.py

Whenever you encounter an error with this message use my_string.encode().

^{(where my_string is the string you're passing to a function/method).}

The encode method of str objects returns the encoded version of the string as a bytes object which you can then use. In this specific instance, socket methods such as .send expect a bytes object as the data to be sent, not a string object.

Since you have an object of type str and you're passing it to a function/method that expects an object of type bytes, an error is raised that clearly explains that:

TypeError: a bytes-like object is required, not 'str'

So the encode method of strings is needed, applied on a str value and returning a bytes value:

>>> s = "Hello world"
>>> print(type(s))
<class 'str'>
>>> byte_s = s.encode()
>>> print(type(byte_s))
<class 'bytes'>
>>> print(byte_s)
b"Hello world"

Here the prefix b in b'Hello world' denotes that this is indeed a bytes object. You can then pass it to whatever function is expecting it in order for it to run smoothly.

Using CSS {height: 100%;} matches the height of the parent. This could be anything, meaning smaller or bigger than the screen. Using {height: 100vh;} matches the height of the viewport.

.container {
    height: 100vh;
    overflow: auto;
}

According to Mozilla's official documents, 1vh is:

Equal to 1% of the height of the viewport's initial containing block.

In oncreate(); write this line->

getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

then implement below method in that class

@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
    case android.R.id.home:
        // app icon in action bar clicked; go home
      onBackPressed();
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

Attaches a change event to the select that gets the text for each selected option and writes them in the div.

You can use jQuery it very face and successful and easy to use

<select name="sweets" multiple="multiple">
  <option>Chocolate</option>
  <option>Candy</option>
  <option>Taffy</option>
  <option selected="selected">Caramel</option>
  <option>Fudge</option>
  <option>Cookie</option>
</select>
<div></div>


$("select").change(function () {
  var str = "";

  $("select option:selected").each(function() {
    str += $( this ).text() + " ";
  });

  $( "div" ).text( str );
}).change();

I figured it out now. When you need to run two commands in exec in a find you need to actually have two separate execs. This finally worked for me.

find . -type f -name "*.rm" -exec ffmpeg -i {} -sameq {}.mp3 \; -exec rm {} \;

Using attr() pointing to an external domain may trigger an error like this in Chrome: "Refused to display document because display forbidden by X-Frame-Options". The workaround to this can be to move the whole iframe HTML code into the script (eg. using .html() in jQuery).

Example:

var divMapLoaded = false;
$("#container").scroll(function() {
    if ((!divMapLoaded) && ($("#map").position().left <= $("#map").width())) {
    $("#map-iframe").html("<iframe id=\"map-iframe\" " +
        "width=\"100%\" height=\"100%\" frameborder=\"0\" scrolling=\"no\" " +
        "marginheight=\"0\" marginwidth=\"0\" " +
        "src=\"http://www.google.it/maps?t=m&amp;cid=0x3e589d98063177ab&amp;ie=UTF8&amp;iwloc=A&amp;brcurrent=5,0,1&amp;ll=41.123115,16.853177&amp;spn=0.005617,0.009943&amp;output=embed\"" +
        "></iframe>");
    divMapLoaded = true;
}

This one worked for me:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

JFrame and JApplet are top level containers. If you wish to create a desktop application, you will use JFrame and if you plan to host your application in browser you will use JApplet.

JComponent is an abstract class for all Swing components and you can use it as the base class for your new component. JPanel is a simple usable component you can use for almost anything.

Since this is for a fun project, the simplest way for you is to work with JPanel and then host it inside JFrame or JApplet. Netbeans has a visual designer for Swing with simple examples.

Use -1 as the start position:

INSTR('JD-EQ-0001', '-', -1)

You just do an opposite comparison. if Col2 <= 1. This will return a boolean Series with False values for those greater than 1 and True values for the other. If you convert it to an int64 dtype, True becomes 1 and False become 0,

df['Col3'] = (df['Col2'] <= 1).astype(int)

If you want a more general solution, where you can assign any number to Col3 depending on the value of Col2 you should do something like:

df['Col3'] = df['Col2'].map(lambda x: 42 if x > 1 else 55)

Or:

df['Col3'] = 0
condition = df['Col2'] > 1
df.loc[condition, 'Col3'] = 42
df.loc[~condition, 'Col3'] = 55

Another way to do this:

first_value = df['Btime'].values[0]

This way seems to be faster than using .iloc:

In [1]: %timeit -n 1000 df['Btime'].values[20]
5.82 µs ± 142 ns per loop (mean ± std. dev. of 7 runs, 1000 loops each)

In [2]: %timeit -n 1000 df['Btime'].iloc[20]
29.2 µs ± 1.28 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

You want to use sections when you want a bit of code/content to render in a placeholder that has been defined in a layout page.

In the specific example you linked, he has defined the RenderSection in the _Layout.cshtml. Any view that uses that layout can define an @section of the same name as defined in Layout, and it will replace the RenderSection call in the layout.

Perhaps you're wondering how we know Index.cshtml uses that layout? This is due to a bit of MVC/Razor convention. If you look at the dialog where he is adding the view, the box "Use layout or master page" is checked, and just below that it says "Leave empty if it is set in a Razor _viewstart file". It isn't shown, but inside that _ViewStart.cshtml file is code like:

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

The way viewstarts work is that any cshtml file within the same directory or child directories will run the ViewStart before it runs itself.

Which is what tells us that Index.cshtml uses Shared/_Layout.cshtml.

Obviously, the standard library provided operator does not know what to do with your user defined type mystruct. It only works for predefined data types. To be able to use it for your own data type, You need to overload operator << to take your user defined data type.

You use an enum instead of a class if the class should have a fixed enumerable number of instances.

Examples:

• DayOfWeek  = 7 instances ? enum
• CardSuit    = 4 instances ? enum
• Singleton  = 1 instance   ? enum
  
  
• Product      = variable number of instances ? class
• User            = variable number of instances ? class
• Date            = variable number of instances ? class

You want set_ticks_position rather than set_label_position:

ax.xaxis.set_ticks_position('top') # the rest is the same

This gives me:

Definitely hash (#) is better because in JavaScript it is a pseudoscheme:

1. pollutes history
2. instantiates new copy of engine
3. runs in global scope and doesn't respect event system.

Of course "#" with an onclick handler which prevents default action is [much] better. Moreover, a link that has the sole purpose to run JavaScript is not really "a link" unless you are sending user to some sensible anchor on the page (just # will send to top) when something goes wrong. You can simply simulate look and feel of link with stylesheet and forget about href at all.

In addition, regarding cowgod's suggestion, particularly this: ...href="javascript_required.html" onclick="... This is good approach, but it doesn't distinguish between "JavaScript disabled" and "onclick fails" scenarios.

This should do it:

SELECT * 
FROM   INFORMATION_SCHEMA.VIEWS 
WHERE  VIEW_DEFINITION like '%YourTableName%'

I had similar issue. Got it solved by changing "Architecture" to "$(ARCHS_STANDARD_32_BIT)" in Build Settings for Project.

Now, you have to select Standard architectures (armv7, arm64) - $(ARCHS_STANDARD) since apple recommends apps to be build on 64-bit architecture. Click : Apple document

New versions of MySQL WorkBench have an option to change specific timeouts.

For me it was under Edit ? Preferences ? SQL Editor ? DBMS connection read time out (in seconds): 600

Changed the value to 6000.

Also unchecked limit rows as putting a limit in every time I want to search the whole data set gets tiresome.

Try the display max_columns setting as follows:

import pandas as pd
from IPython.display import display

df = pd.read_csv("some_data.csv")
pd.options.display.max_columns = None
display(df)

Or

pd.set_option('display.max_columns', None)

Edit: Pandas 0.11.0 backwards

This is deprecated but in versions of Pandas older than 0.11.0 the max_columns setting is specified as follows:

pd.set_printoptions(max_columns=500)

Two approaches are to write to a string buffer or to write lines to a list and join them later. I think the StringIO approach is more pythonic, but didn't work before Python 2.6.

from io import StringIO

with StringIO() as s:
   print("Hello", file=s)
   print("Goodbye", file=s)
   # And later...
   with open('myfile', 'w') as f:
       f.write(s.getvalue())

You can also use these without a ContextMananger (s = StringIO()). Currently, I'm using a context manager class with a print function. This fragment might be useful to be able to insert debugging or odd paging requirements:

class Report:
    ... usual init/enter/exit
    def print(self, *args, **kwargs):
        with StringIO() as s:
            print(*args, **kwargs, file=s)
            out = s.getvalue()
        ... stuff with out

with Report() as r:
   r.print(f"This is {datetime.date.today()}!", 'Yikes!', end=':')

For me just removed the OLE DB source from SSIS and added again. Worked!

I found a new error code which is not documented above: CFNetworkErrorCode -1022

Error Domain=NSURLErrorDomain Code=-1022 "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection."

Purpose of view is displaying model. You should use controller to redirect request before creating model and passing it to view. Use Controller.RedirectToAction method for this.

Related, if you open a file that uses both tabs and spaces, assuming you've got

set expandtab ts=4 sw=4 ai

You can replace all the tabs with spaces in the entire file with

:%retab

I am having the same issue here is my scenario

i put empty('') where value is NULL now this '' value does not match with the parent table's id

here is things need to check , all value with presented in parent table otherwise remove data from parent table then try

If you can't solve the problem for the rectangle try dividing the problem in to easier problems. Divide the rectangle into 2 triangles an check if the point is inside any of them like they explain in here

Essentially, you cycle through the edges on every two pairs of lines from a point. Then using cross product to check if the point is between the two lines using the cross product. If it's verified for all 3 points, then the point is inside the triangle. The good thing about this method is that it does not create any float-point errors which happens if you check for angles.

$( ".selector" ).datepicker( "option", "dateFormat", 'yy-mm-dd' );

See: http://jqueryui.com/demos/datepicker/ and http://docs.jquery.com/UI/Datepicker/formatDate#utility-formatDate

If you paste the listing into your word processor instead of Notepad, (since each file name is in quotation marks with the full path name), you can highlight all the stuff you don't want on the first file, then use Find and Replace to replace every occurrence of that with nothing. Same with the ending quote (").

It makes a nice clean list of file names.

Here's an example from Northwind 2007:

SELECT [Product ID], [Order Date], [Company Name], [Transaction], [Quantity]
FROM [Product Orders]
UNION SELECT [Product ID], [Creation Date], [Company Name], [Transaction], [Quantity]
FROM [Product Purchases]
ORDER BY [Order Date] DESC;

The ORDER BY clause just needs to be the last statement, after you've done all your unioning. You can union several sets together, then put an ORDER BY clause after the last set.

Yes, it can be done.
It is based on the new html5 "download" attribute of anchor tags.
The flow should be something like this :

1. load the image
2. draw the image into a canvas with the crop boundaries specified
3. get the image data from the canvas and make it a href attribute for an anchor tag in the dom
4. add the download attribute (download="desired-file-name") to that a element That's it. all the user has to do is click your "download link" and the image will be downloaded to his pc.

I'll come back with a demo when I get the chance.

Update
Here's the live demo as I promised. It takes the jsfiddle logo and crops 5px of each margin.
The code looks like this :

var img = new Image();
img.onload = function(){
    var cropMarginWidth = 5,
        canvas = $('<canvas/>')
                    .attr({
                         width: img.width - 2 * cropMarginWidth,
                         height: img.height - 2 * cropMarginWidth
                     })
                    .hide()
                    .appendTo('body'),
        ctx = canvas.get(0).getContext('2d'),
        a = $('<a download="cropped-image" title="click to download the image" />'),
        cropCoords = {
            topLeft : {
                x : cropMarginWidth,
                y : cropMarginWidth 
            },
            bottomRight :{
                x : img.width - cropMarginWidth,
                y : img.height - cropMarginWidth
            }
        };

    ctx.drawImage(img, cropCoords.topLeft.x, cropCoords.topLeft.y, cropCoords.bottomRight.x, cropCoords.bottomRight.y, 0, 0, img.width, img.height);
    var base64ImageData = canvas.get(0).toDataURL();


    a
        .attr('href', base64ImageData)
        .text('cropped image')
        .appendTo('body');

    a
        .clone()
        .attr('href', img.src)
        .text('original image')
        .attr('download','original-image')
        .appendTo('body');

    canvas.remove();
}
img.src = 'some-image-src';

Update II
Forgot to mention : of course there is a downside :(.
Because of the same-origin policy that is applied to images too, if you want to access an image's data (through the canvas method toDataUrl).
So you would still need a server-side proxy that would serve your image as if it were hosted on your domain.

Update III Although I can't provide a live demo for this (for security reasons), here is a php sample code that solves the same-origin policy :

file proxy.php :

$imgData = getimagesize($_GET['img']);
header("Content-type: " . $imgData['mime']);
echo file_get_contents($_GET['img']);  

This way, instead of loading the external image direct from it's origin :

img.src = 'http://some-domain.com/imagefile.png';

You can load it through your proxy :

img.src = 'proxy.php?img=' + encodeURIComponent('http://some-domain.com/imagefile.png');  

And here's a sample php code for saving the image data (base64) into an actual image :

file save-image.php :

$data = preg_replace('/data:image\/(png|jpg|jpeg|gif|bmp);base64/','',$_POST['data']);
$data = base64_decode($data);
$img = imagecreatefromstring($data);

$path = 'path-to-saved-images/';
// generate random name
$name  = substr(md5(time()),10);
$ext = 'png';
$imageName = $path.$name.'.'.$ext;

// write the image to disk
imagepng($img,  $imageName);
imagedestroy($img);
// return the image path
echo $imageName;

All you have to do then is post the image data to this file and it will save the image to disc and return you the existing image filename.

Of course all this might feel a bit complicated, but I wanted to show you that what you're trying to achieve is possible.

try this

- (BOOL) textView: (UITextView*) textView shouldChangeTextInRange: (NSRange) range replacementText: (NSString*) text
{
    if ([text isEqualToString:@"\n"]) {
        [textView resignFirstResponder];
        return NO;
    }
    return YES;
}

I just thought about this rather simple solution:

1. Define a view function do_work(req, param) like you would with any other view, with URL mapping, return a HttpResponse and so on.
2. Set up a cron job with your timing preferences (or using AT or Scheduled Tasks in Windows) which runs curl http://localhost/your/mapped/url?param=value.

You can add parameters but just adding parameters to the URL.

Tell me what you guys think.

[Update] I'm now using runjob command from django-extensions instead of curl.

My cron looks something like this:

@hourly python /path/to/project/manage.py runjobs hourly

... and so on for daily, monthly, etc'. You can also set it up to run a specific job.

I find it more managable and a cleaner. Doesn't require mapping a URL to a view. Just define your job class and crontab and you're set.

Here is a simple reliable way...

Put the following code in your Activity, and the tick() method will be called every second in the UI thread while your activity is in the "resumed" state. Of course, you can change the tick() method to do what you want, or to be called more or less frequently.

@Override
public void onPause() {
    _handler = null;
    super.onPause();
}

private Handler _handler;

@Override
public void onResume() {
    super.onResume();
    _handler = new Handler();
    Runnable r = new Runnable() {
        public void run() {
            if (_handler == _h0) {
                tick();
                _handler.postDelayed(this, 1000);
            }
        }

        private final Handler _h0 = _handler;
    };
    r.run();
}

private void tick() {
    System.out.println("Tick " + System.currentTimeMillis());
}

For those interested, the "_h0=_handler" code is necessary to avoid two timers running simultaneously if your activity is paused and resumed within the tick period.

Are you running Android M? If so, this is because it's not enough to declare permissions in the manifest. For some permissions, you have to explicitly ask user in the runtime: http://developer.android.com/training/permissions/requesting.html

Add-Content is default ASCII and add new line however Add-Content brings locked files issues too.

In VS2017. I had to edit my .sln file and had to update the VWDPort = "5010" setting. None of the other solutions posted here worked.

I'm using bootstrap.
I used css parameters.

.table {
  table-layout:fixed;
}

.table td {
  white-space: nowrap;

  text-overflow: ellipsis;
}

and bootstrap grid system parameters, like this.

<td class="col-sm-2">hoge</td>

You can do it by combining tr and wc commands. For example, to count e in the string referee

echo "referee" | tr -cd 'e' | wc -c

output

4

Explanations: Command tr -cd 'e' removes all characters other than 'e', and Command wc -c counts the remaining characters.

Multiple lines of input are also good for this solution, like command cat mytext.txt | tr -cd 'e' | wc -c can counts e in the file mytext.txt, even thought the file may contain many lines.

*** Update ***

To solve the multiple spaces in from of the number (@tom10271), simply append a piped tr command:

 tr -d ' '

For example:

echo "referee" | tr -cd 'e' | wc -c | tr -d ' '

Update the create action as below:

def create
  ...
  respond_to do |format|
    if @reservation.save
      format.html do
        redirect_to '/'
      end
      format.json { render json: @reservation.to_json }
    else
      format.html { render 'new'} ## Specify the format in which you are rendering "new" page
      format.json { render json: @reservation.errors } ## You might want to specify a json format as well
    end
  end
end

You are using respond_to method but anot specifying the format in which a new page is rendered. Hence, the error ActionController::UnknownFormat .

In IIS you can declare the mime type for WOFF2 font files by adding the following to your project's web.config:

<system.webServer>
  <staticContent>
    <remove fileExtension=".woff2" />
    <mimeMap fileExtension=".woff2" mimeType="font/woff2" />
  </staticContent>
</system.webServer>

Update: The mime type may be changing according to the latest W3C Editor's Draft WOFF2 spec. See Appendix A: Internet Media Type Registration section 6.5. WOFF 2.0 which states the latest proposed format is font/woff2

Wade73's answer for decimals doesn't quite work. I've modified it to allow only a single decimal point.

declare @MyTable table(MyVar nvarchar(10));
insert into @MyTable (MyVar) 
values 
    (N'1234')
    , (N'000005')
    , (N'1,000')
    , (N'293.8457')
    , (N'x')
    , (N'+')
    , (N'293.8457.')
    , (N'......');

-- This shows that Wade73's answer allows some non-numeric values to slip through.
select * from (

This is an answer to @craq :

I just compiled the file from C source and set it to be executable with chmod. There were no warning or error messages from gcc.

I'm a bit surprised that you had to 'set it to executable' -- my gcc always sets the executable flag itself. This suggests to me that gcc didn't expect this to be the final executable file, or that it didn't expect it to be executable on this system.

Now I've tried to just create the object file, like so:

$ gcc -c -o hello hello.c
$ chmod +x hello

(hello.c is a typical "Hello World" program.) But my error message is a bit different:

$ ./hello
bash: ./hello: cannot execute binary file: Exec format error`

On the other hand, this way, the output of the file command is identical to yours:

$ file hello
hello: ELF 64-bit LSB  relocatable, x86-64, version 1 (SYSV), not stripped

Whereas if I compile correctly, its output is much longer.

$ gcc -o hello hello.c
$ file hello
hello: ELF 64-bit LSB  executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=131bb123a67dd3089d23d5aaaa65a79c4c6a0ef7, not stripped

What I am saying is: I suspect it has something to do with the way you compile and link your code. Maybe you can shed some light on how you do that?

I was looking for a different answer for the question title, so maybe other people will be too.

To set type as an ObjectId (so you may reference author as the author of book, for example), you may do like:

const Book = mongoose.model('Book', {
  author: {
    type: mongoose.Schema.Types.ObjectId, // here you set the author ID
                                          // from the Author colection, 
                                          // so you can reference it
    required: true
  },
  title: {
    type: String,
    required: true
  }
});

On Selenium >= 3.41 (C#) the rigth syntax is:

webDriver = webDriver.SwitchTo().Frame(webDriver.FindElement(By.Name("icontent")));

I stumbled over the same issue and found a nice solution which does not need any static ip configuration:

You can access a service via it's DNS name (as mentioned by you): servicename.namespace.svc.cluster.local

You can use that DNS name to reference it in another namespace via a local service:

kind: Service
apiVersion: v1
metadata:
  name: service-y
  namespace: namespace-a
spec:
  type: ExternalName
  externalName: service-x.namespace-b.svc.cluster.local
  ports:
  - port: 80

Well, there are lots of exceptions to throw, but here is how you throw an exception:

throw new IllegalArgumentException("INVALID");

Also, yes, you can create your own custom exceptions.

A note about exceptions. When you throw an exception (like above) and you catch the exception: the String that you supply in the exception can be accessed throw the getMessage() method.

try{
    methodThatThrowsException();
}catch(IllegalArgumentException e)
{
  e.getMessage();
}

This is not a PowerShell-specific answer, but you could authenticate against the share using "NET USE" first:

net use \\server\share /user:<domain\username> <password>

And then do whatever you need to do in PowerShell...

First the bad answer. From this question there's a one-liner that you can run:

echo "" > $(docker inspect --format='{{.LogPath}}' <container_name_or_id>)

instead of echo, there's the simpler:

: > $(docker inspect --format='{{.LogPath}}' <container_name_or_id>)

or there's the truncate command:

truncate -s 0 $(docker inspect --format='{{.LogPath}}' <container_name_or_id>)

I'm not a big fan of either of those since they modify Docker's files directly. The external log deletion could happen while docker is writing json formatted data to the file, resulting in a partial line, and breaking the ability to read any logs from the docker logs cli. For an example of that happening, see this comment on duketwo's answer

Instead, you can have Docker automatically rotate the logs for you. This is done with additional flags to dockerd if you are using the default JSON logging driver:

dockerd ... --log-opt max-size=10m --log-opt max-file=3

You can also set this as part of your daemon.json file instead of modifying your startup scripts:

{
  "log-driver": "json-file",
  "log-opts": {"max-size": "10m", "max-file": "3"}
}

These options need to be configured with root access. Make sure to run a systemctl reload docker after changing this file to have the settings applied. This setting will then be the default for any newly created containers. Note, existing containers need to be deleted and recreated to receive the new log limits.

Similar log options can be passed to individual containers to override these defaults, allowing you to save more or fewer logs on individual containers. From docker run this looks like:

docker run --log-driver json-file --log-opt max-size=10m --log-opt max-file=3 ...

or in a compose file:

version: '3.7'
services:
  app:
    image: ...
    logging:
      options:
        max-size: "10m"
        max-file: "3"

For additional space savings, you can switch from the json log driver to the "local" log driver. It takes the same max-size and max-file options, but instead of storing in json it uses a binary syntax that is faster and smaller. This allows you to store more logs in the same sized file. The daemon.json entry for that looks like:

{
  "log-driver": "local",
  "log-opts": {"max-size": "10m", "max-file": "3"}
}

The downside of the local driver is external log parsers/forwarders that depended on direct access to the json logs will no longer work. So if you use a tool like filebeat to send to Elastic, or Splunk's universal forwarder, I'd avoid the "local" driver.

I've got a bit more on this in my Tips and Tricks presentation.

Empty password worked for me on my Mac

keytool -list -v -keystore ~/.android/debug.keystore 

hit Enter then It's show you

Enter keystore password:  

here just hit Enter for empty password

Error Code: 1005 -- there is a wrong primary key reference in your code

Usually it's due to a referenced foreign key field that does not exist. It might be you have a typo mistake, or check case it should be same, or there's a field-type mismatch. Foreign key-linked fields must match definitions exactly.

Some known causes may be:

1. The two key fields type and/or size doesn’t match exactly. For example, if one is INT(10) the key field needs to be INT(10) as well and not INT(11) or TINYINT. You may want to confirm the field size using SHOW CREATE TABLE because Query Browser will sometimes visually show just INTEGER for both INT(10) and INT(11). You should also check that one is not SIGNED and the other is UNSIGNED. They both need to be exactly the same.
2. One of the key field that you are trying to reference does not have an index and/or is not a primary key. If one of the fields in the relationship is not a primary key, you must create an index for that field.
3. The foreign key name is a duplicate of an already existing key. Check that the name of your foreign key is unique within your database. Just add a few random characters to the end of your key name to test for this.
4. One or both of your tables is a MyISAM table. In order to use foreign keys, the tables must both be InnoDB. (Actually, if both tables are MyISAM then you won’t get an error message - it just won’t create the key.) In Query Browser, you can specify the table type.
5. You have specified a cascade ON DELETE SET NULL, but the relevant key field is set to NOT NULL. You can fix this by either changing your cascade or setting the field to allow NULL values.
6. Make sure that the Charset and Collate options are the same both at the table level as well as individual field level for the key columns.
7. You have a default value (that is, default=0) on your foreign key column
8. One of the fields in the relationship is part of a combination (composite) key and does not have its own individual index. Even though the field has an index as part of the composite key, you must create a separate index for only that key field in order to use it in a constraint.
9. You have a syntax error in your ALTER statement or you have mistyped one of the field names in the relationship
10. The name of your foreign key exceeds the maximum length of 64 characters.

Well I always use the same easy way and it works for me. In your HTML keep the type as text (like this):

<input type="text" class="textfield" value="" id="onlyNumbers" name="onlyNumbers" onkeypress="return isNumber(event)" onpaste="return false;"/>

After this you only need to add a method on javascript

<script type="text/javascript">     
function isNumber(evt) {
        evt = (evt) ? evt : window.event;
        var charCode = (evt.which) ? evt.which : evt.keyCode;
        if ( (charCode > 31 && charCode < 48) || charCode > 57) {
            return false;
        }
        return true;
    }
</script>

With this easy validation you will only get positive numbers as you wanted. You can modify the charCodes to add more valid keys to your method.

Here´s the code working: Only numbers validation

It may make things more elegant to wrap it in a property.

string MySessionVar
{
   get{
      return Session["MySessionVar"] ?? String.Empty;
   }
   set{
      Session["MySessionVar"] = value;
   }
}

then you can treat it as a string.

if( String.IsNullOrEmpty( MySessionVar ) )
{
   // do something
}

A dangling pointer is one that has a value (not NULL) which refers to some memory which is not valid for the type of object you expect. For example if you set a pointer to an object then overwrote that memory with something else unrelated or freed the memory if it was dynamically allocated.

A memory leak is when you dynamically allocate memory from the heap but never free it, possibly because you lost all references to it.

They are related in that they are both situations relating to mismanaged pointers, especially regarding dynamically allocated memory. In one situation (dangling pointer) you have likely freed the memory but tried to reference it afterwards; in the other (memory leak), you have forgotten to free the memory entirely!

You can use a pseudo element to create the overlay.

.testclass {
  background-image: url("../img/img.jpg");
  position: relative;
}
.testclass:before {
  content: "";
  position: absolute;
  left: 0; right: 0;
  top: 0; bottom: 0;
  background: rgba(0,0,0,.5);
}

Check out the foundation rapid prototyping framework they handled this quite nicely, basically they allow you to use HTML like this:

<div class="row">
    <div class="four columns">
    </div>
    <div class="four columns">
    </div>
    <div class="four columns">
    </div>
</div>

This is the simplest HTML/CSS grid system that I've come across, it's based on 12 column grid.

Basically the columns are given a % width and left margin relative to the parent row. They columns have float set to left, position set to relative, and display set to block.

The row has several properties set on it that care core of an issue that normally causes the containing div to collapse to height of 0 preventing the following divs from getting 'pushed' down as they should.

You can find examples of using the foundation grid system here: http://foundation.zurb.com/docs/grid.php

If you don't want to use the entire framework the following CSS should do the trick with the example code I provided:

.row:after {
    content: "";
    clear: both;
    display: table;
}

.four.column {
    float: left;
    width: 33%;
}

If you really specifically want a left center and right columns then use code like this:

CSS:

.row:after {
    content: "";
    clear: both;
    display: table;
}

.left {
    float: left;
    width: 100px;
}

.center {
    margin: 0 auto;
    width: 100px;
}

.right {
    float: right;
    width: 100px;
}

HTML:

<div class="row">
    <div class="left">left</div>
    <div class="right">right</div>
    <div class="center">center</div>
</div>

If you don't want duplicates in a Collection, you should consider why you're using a Collection that allows duplicates. The easiest way to remove repeated elements is to add the contents to a Set (which will not allow duplicates) and then add the Set back to the ArrayList:

Set<String> set = new HashSet<>(yourList);
yourList.clear();
yourList.addAll(set);

Of course, this destroys the ordering of the elements in the ArrayList.

Without CSS, you basically are stuck with using an image tag. Basically make an image of the text and add the underline. That basically means your page is useless to a screen reader.

With CSS, it is simple.

HTML:

<u class="dotted">I like cheese</u>

CSS:

u.dotted{
  border-bottom: 1px dashed #999;
  text-decoration: none; 
}

Running Example

Example page

<!DOCTYPE HTML>
<html>
<head>
    <style>
        u.dotted{
          border-bottom: 1px dashed #999;
          text-decoration: none; 
        }
    </style>
</head>
<body>
    <u class="dotted">I like cheese</u>
</body>
</html>

You can enable connection logging. For SQL Server 2008, you can enable Login Auditing. In SQL Server Management Studio, open SQL Server Properties > Security > Login Auditing select "Both failed and successful logins".

Make sure to restart the SQL Server service.

Once you've done that, connection attempts should be logged into SQL's error log. The physical logs location can be determined here.

You'd need to remove the blank table cell element entirely, and change the colspan attribute on another cell in the row to encompass the released space, e.g.:

refToCellToRemove.remove();
refTocellToExpand.colspan = 4;

Note that setting it via setAttribute (which would otherwise be correct) will not work properly on IE.

Beware: IE does some very strange table layout things when you muck about with colspans dynamically. If you can avoid it, I would.

I found this:

<embed type="application/x-vlc-plugin"
pluginspage="http://www.videolan.org"version="VideoLAN.VLCPlugin.2"  width="100%"        
height="100%" id="vlc" loop="yes"autoplay="yes" target="http://10.1.2.201:8000/"></embed>

I don't see that in your code anywhere.... I think that's all you need and the target would be the location of your video...

and here is more info on the vlc plugin:

Another thing to check is that the address for the video file is correct....
