I found a good article about using the WMP with Firefox on MSDN.

Based on MSDN's article and after doing some trials and errors, I found using JavaScript is better than using conditional comments or nested "EMBED/OBJECT" tags.

I made a JS function that generate WMP object based on given arguments:

<script type="text/javascript">
    function generateWindowsMediaPlayer(
        holderId,   // String
        height,     // Number
        width,      // Number
        videoUrl    // String
        // you can declare more arguments for more flexibility
        ) {
        var holder = document.getElementById(holderId);

        var player = '<object ';
        player += 'height="' + height.toString() + '" ';
        player += 'width="' + width.toString() + '" ';

        videoUrl = encodeURI(videoUrl); // Encode for special characters

        if (navigator.userAgent.indexOf("MSIE") < 0) {
            // Chrome, Firefox, Opera, Safari
            //player += 'type="application/x-ms-wmp" '; //Old Edition
            player += 'type="video/x-ms-wmp" '; //New Edition, suggested by MNRSullivan (Read Comments)
            player += 'data="' + videoUrl + '" >';
        }
        else {
            // Internet Explorer
            player += 'classid="clsid:6BF52A52-394A-11d3-B153-00C04F79FAA6" >';
            player += '<param name="url" value="' + videoUrl + '" />';
        }

        player += '<param name="autoStart" value="false" />';
        player += '<param name="playCount" value="1" />';
        player += '</object>';

        holder.innerHTML = player;
    }
</script>

Then I used that function by writing some markups and inline JS like these:

<div id='wmpHolder'></div>

<script type="text/javascript">        
    window.addEventListener('load', generateWindowsMediaPlayer('wmpHolder', 240, 320, 'http://mysite.com/path/video.ext'));
</script>

You can use jQuery.ready instead of window load event to making the codes more backward-compatible and cross-browser.

I tested the codes over IE 9-10, Chrome 27, Firefox 21, Opera 12 and Safari 5, on Windows 7/8.

If you want to filter rows by a certain number of columns with null values, you may use this:

df.iloc[df[(df.isnull().sum(axis=1) >= qty_of_nuls)].index]

So, here is the example:

Your dataframe:

>>> df = pd.DataFrame([range(4), [0, np.NaN, 0, np.NaN], [0, 0, np.NaN, 0], range(4), [np.NaN, 0, np.NaN, np.NaN]])
>>> df
     0    1    2    3
0  0.0  1.0  2.0  3.0
1  0.0  NaN  0.0  NaN
2  0.0  0.0  NaN  0.0
3  0.0  1.0  2.0  3.0
4  NaN  0.0  NaN  NaN

If you want to select the rows that have two or more columns with null value, you run the following:

>>> qty_of_nuls = 2
>>> df.iloc[df[(df.isnull().sum(axis=1) >=qty_of_nuls)].index]
     0    1    2   3
1  0.0  NaN  0.0 NaN
4  NaN  0.0  NaN NaN

To post Chris Dutrow's comment here as answer:

style="table-layout:fixed;" 

in the style of the table itself is what worked for me. Thanks Chris!

Full example:

<table width="55" height="55" border="0" cellspacing="0" cellpadding="0" style="border-radius:50%; border:0px solid #000000;table-layout:fixed" align="center" bgcolor="#152b47">
  <tbody>
    <td style="color:#ffffff;font-family:TW-Averta-Regular,Averta,Helvetica,Arial;font-size:11px;overflow:hidden;width:55px;text-align:center;valign:top;whitespace:nowrap;">

     Your table content here

    </td>
  </tbody>
</table>

In addition to Biff MaGriff's answer. To export the file using JQuery, redirect the user to a new page.

$('#btn_export').click(function () {
    window.location.href = 'NewsLetter/Export';
});

You can use the Google Maps API for that. See the blog post below for more information.

http://stuff.nekhbet.ro/2008/12/12/how-to-get-coordinates-for-a-given-address-using-php.html

this code will disable Right-Click on Win or Click and hold on mac to open "contextmenu"

$("img").on("contextmenu",function(e){return false;});

It's so simple and always works fine. and it's not depends on OS or Browser that you're using.

Notification.Builder API 11 or NotificationCompat.Builder API 1

This is a usage example.

Intent notificationIntent = new Intent(ctx, YourClass.class);
PendingIntent contentIntent = PendingIntent.getActivity(ctx,
        YOUR_PI_REQ_CODE, notificationIntent,
        PendingIntent.FLAG_CANCEL_CURRENT);

NotificationManager nm = (NotificationManager) ctx
        .getSystemService(Context.NOTIFICATION_SERVICE);

Resources res = ctx.getResources();
Notification.Builder builder = new Notification.Builder(ctx);

builder.setContentIntent(contentIntent)
            .setSmallIcon(R.drawable.some_img)
            .setLargeIcon(BitmapFactory.decodeResource(res, R.drawable.some_big_img))
            .setTicker(res.getString(R.string.your_ticker))
            .setWhen(System.currentTimeMillis())
            .setAutoCancel(true)
            .setContentTitle(res.getString(R.string.your_notif_title))
            .setContentText(res.getString(R.string.your_notif_text));
Notification n = builder.build();

nm.notify(YOUR_NOTIF_ID, n);

Crosstab function is available under the tablefunc extension. You'll have to create this extension one time for the database.

CREATE EXTENSION tablefunc;

You can use the below code to create pivot table using cross tab:

create table test_Crosstab( section text,
<br/>status text,
<br/>count numeric)

<br/>insert into test_Crosstab values ( 'A','Active',1)
                <br/>,( 'A','Inactive',2)
                <br/>,( 'B','Active',4)
                <br/>,( 'B','Inactive',5)

select * from crosstab(
<br/>'select section
    <br/>,status
    <br/>,count
    <br/>from test_crosstab'
    <br/>)as ctab ("Section" text,"Active" numeric,"Inactive" numeric)

1· Do I need these DLL's?

It depends since Dependency Walker is a little bit out of date and may report the wrong dependency.

2. Where can I get them?

most dlls can be found at https://www.dll-files.com

I believe they are supposed to located in C:\Windows\System32\Wer.dll and C:\Program Files\Internet Explorer\Ieshims.dll

For me leshims.dll can be placed at C:\Windows\System32\. Context: windows 7 64bit.

Call

window.frames['resultFrame'].Reset();

You could also try:

import os
os.system("start \"\" http://example.com")

This, other than @aaronasterling ´s answer has the advantage that it opens the default web browser. Be sure not to forget the "http://".

You shouldn't need a $watch. Just bind to resize event on window:

DEMO

'use strict';

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

app.directive('myDirective', ['$window', function ($window) {

     return {
        link: link,
        restrict: 'E',
        template: '<div>window size: {{width}}px</div>'
     };

     function link(scope, element, attrs){

       scope.width = $window.innerWidth;

       angular.element($window).bind('resize', function(){

         scope.width = $window.innerWidth;

         // manuall $digest required as resize event
         // is outside of angular
         scope.$digest();
       });

     }

 }]);

It isn't built-in, but you can make a subclass of list that takes tuples as "indexes" if you'd like:

class MyList(list):

    def __getitem__(self, index):
        if isinstance(index, tuple):
            return [self[i] for i in index]
        return super(MyList, self).__getitem__(index)


seq = MyList("foo bar baaz quux mumble".split())
print seq[0]
print seq[2,4]
print seq[1::2]

printing

foo
['baaz', 'mumble']
['bar', 'quux']

• Save the all project
• Right click in the Solution Explorer (SE), "Copy"
• Right click on the project name in the SE (this is the first line), "Paste". It will create a "Copy of .....vb" form
• Right click on this new form in SE, "View code", and change its class name to the name, that you wanna use for the Form
• Left click on the new form in SE and rewrite its name for the one, that you used in the class name (and .vb in the end)
• Build - if it has no error, you win! :)

public class TypedProperty<T> : Property
{
    public T TypedValue
    {
        get { return (T)(object)base.Value; }
        set { base.Value = value.ToString();}
    }
}

I using converting via an object. It is a little bit simpler.

The formatting can be done like this (I assumed you meant HH:MM instead of HH:SS, but it's easy to change):

Time.now.strftime("%d/%m/%Y %H:%M")
#=> "14/09/2011 14:09"

Updated for the shifting:

d = DateTime.now
d.strftime("%d/%m/%Y %H:%M")
#=> "11/06/2017 18:11"
d.next_month.strftime("%d/%m/%Y %H:%M")
#=> "11/07/2017 18:11"

You need to require 'date' for this btw.

c_str returns a const char* that points to a null-terminated string (i.e. a C-style string). It is useful when you want to pass the "contents"¹ of an std::string to a function that expects to work with a C-style string.

For example, consider this code:

std::string str("Hello world!");
int pos1 = str.find_first_of('w');

int pos2 = strchr(str.c_str(), 'w') - str.c_str();

if (pos1 == pos2) {
    printf("Both ways give the same result.\n");
}

See it in action.

Notes:

¹ This is not entirely true because an std::string (unlike a C string) can contain the \0 character. If it does, the code that receives the return value of c_str() will be fooled into thinking that the string is shorter than it really is, since it will interpret \0 as the end of the string.

Supposing you have a writable "uploads" folder in your application:

You can define a param like this:

Yii::$app->params['uploadPath'] = realpath(Yii::$app->basePath) . '/uploads/';

Then you can simply use the parameter as:

$path1 = Yii::$app->params['uploadPath'] . $filename;

Just depending on if you are using advanced or simple template the base path will be (following the link provided by phazei):

Simple @app: Your application root directory

Advanced @app: Your application root directory (either frontend or backend or console depending on where you access it from)

This way the application will be more portable than using realpath(dirname(__FILE__).'/../../'));

In case you're using postgres, you can use something like this:

class ChessBoard(models.Model):

    board = ArrayField(
        ArrayField(
            models.CharField(max_length=10, blank=True),
            size=8,
        ),
        size=8,
    )

if you need more details you can read in the link below: https://docs.djangoproject.com/pt-br/1.9/ref/contrib/postgres/fields/

function bindFirst(owner, event, handler) {
    owner.unbind(event, handler);
    owner.bind(event, handler);

    var events = owner.data('events')[event];
    events.unshift(events.pop());

    owner.data('events')[event] = events;
}

Ubuntu 18.04.5 LTS (Bionic Beaver):

apt --reinstall install python3-debian
apt --reinstall install python3-six

If /usr/bin/chardet3 fails with error "ModuleNotFoundError: No module named 'pkg_resources'":

apt --reinstall install python3-pkg-resources

As always, I recommend reading this article about date and time in Java so that you understand it.

The basic idea is that 'under the hood' everything is done in UTC milliseconds since the epoch. This means it is easiest if you operate without using time zones at all, with the exception of String formatting for the user.

Therefore I would skip most of the steps you have suggested.

1. Set the time on an object (Date, Calendar etc).
2. Set the time zone on a formatter object.
3. Return a String from the formatter.

Alternatively, you can use Joda time. I have heard it is a much more intuitive datetime API.

Try passing width=200 as additional paramater when creating the Label.

This should work in creating label with specified width.

If you want to change it later, you can use:

label.config(width=200)

As you want to change the size of font itself you can try:

label.config(font=("Courier", 44))

Try <input type="number" step="any" />

It won't have validation problems and the arrows will have step of "1"

Constraint validation: When the element has an allowed value step, and the result of applying the algorithm to convert a string to a number to the string given by the element's value is a number, and that number subtracted from the step base is not an integral multiple of the allowed value step, the element is suffering from a step mismatch.

The following range control only accepts values in the range 0..1, and allows 256 steps in that range:

<input name=opacity type=range min=0 max=1 step=0.00392156863>

The following control allows any time in the day to be selected, with any accuracy (e.g. thousandth-of-a-second accuracy or more):

<input name=favtime type=time step=any>

Normally, time controls are limited to an accuracy of one minute.

http://www.w3.org/TR/2012/WD-html5-20121025/common-input-element-attributes.html#attr-input-step

Be careful using the answer provide by @DevNG. Arrays.asList() returns internal implementation of ArrayList that doesn't implement some useful methods like add(), delete(), etc. If you call them an UnsupportedOperationException will be thrown. In order to get real ArrayList instance you need to write something like this:

List<Video> = new ArrayList<>(Arrays.asList(videoArray));

I think that still there isnt any answer here with easy and readable working example. Use MutationObserver interface to detect DOM changes, like this:

var observer = new MutationObserver(function(mutations) {_x000D_
    if ($("p").length) {_x000D_
        console.log("Exist, lets do something");_x000D_
        observer.disconnect(); _x000D_
        //We can disconnect observer once the element exist if we dont want observe more changes in the DOM_x000D_
    }_x000D_
});_x000D_
_x000D_
// Start observing_x000D_
observer.observe(document.body, { //document.body is node target to observe_x000D_
    childList: true, //This is a must have for the observer with subtree_x000D_
    subtree: true //Set to true if changes must also be observed in descendants._x000D_
});_x000D_
            _x000D_
$(document).ready(function() {_x000D_
    $("button").on("click", function() {_x000D_
        $("p").remove();_x000D_
        setTimeout(function() {_x000D_
            $("#newContent").append("<p>New element</p>");_x000D_
        }, 2000);_x000D_
    });_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<button>New content</button>_x000D_
<div id="newContent"></div>

Note: Spanish Mozilla docs about MutationObserver are more detailed if you want more information.

Yes, this is a safe conversion. C requires it to work. This guarantee is in section 5.2.1 paragraph 2 of the latest ISO C standard, a recent draft of which is N1570:

Both the basic source and basic execution character sets shall have the following members:
[...]
the 10 decimal digits
0 1 2 3 4 5 6 7 8 9
[...]
In both the source and execution basic character sets, the value of each character after 0 in the above list of decimal digits shall be one greater than the value of the previous.

Both ASCII and EBCDIC, and character sets derived from them, satisfy this requirement, which is why the C standard was able to impose it. Note that letters are not contiguous iN EBCDIC, and C doesn't require them to be.

There is no library function to do it for a single char, you would need to build a string first:

int digit_to_int(char d)
{
 char str[2];

 str[0] = d;
 str[1] = '\0';
 return (int) strtol(str, NULL, 10);
}

You could also use the atoi() function to do the conversion, once you have a string, but strtol() is better and safer.

As commenters have pointed out though, it is extreme overkill to call a function to do this conversion; your initial approach to subtract '0' is the proper way of doing this. I just wanted to show how the recommended standard approach of converting a number as a string to a "true" number would be used, here.

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

You can do something like this:

import requests
import random

url = "https://images.pexels.com/photos/1308881/pexels-photo-1308881.jpeg? auto=compress&cs=tinysrgb&dpr=1&w=500"
name=random.randrange(1,1000)
filename=str(name)+".jpg"
response = requests.get(url)
if response.status_code.ok:
   with open(filename,'w') as f:
    f.write(response.content)

For this problem, I had to use : sudo /usr/share/elasticsearch/bin/elasticsearch start

to be able to get something on ports 9200/9300 (sudo netstat -ntlp) and a response to:

curl -XGET http://localhost:9200

What worked for me was to write a console app separately that did what I wanted it to do, compile it down to an exe, and then do Process.Start("MyConsoleapp.exe","Arguments")

The data you want is in the "cols" meta-data table:

SELECT * FROM COLS WHERE COLUMN_NAME = 'id'

This one will give you a list of tables that have all of the columns you want:

select distinct
  C1.TABLE_NAME
from
  cols c1
  inner join
  cols c2
  on C1.TABLE_NAME = C2.TABLE_NAME
  inner join
  cols c3
  on C2.TABLE_NAME = C3.TABLE_NAME
  inner join
  cols c4
  on C3.TABLE_NAME = C4.TABLE_NAME  
  inner join
  tab t
  on T.TNAME = C1.TABLE_NAME
where T.TABTYPE = 'TABLE' --could be 'VIEW' if you wanted
  and upper(C1.COLUMN_NAME) like upper('%id%')
  and upper(C2.COLUMN_NAME) like upper('%fname%')
  and upper(C3.COLUMN_NAME) like upper('%lname%')
  and upper(C4.COLUMN_NAME) like upper('%address%')  

To do this in a different schema, just specify the schema in front of the table, as in

SELECT * FROM SCHEMA1.COLS WHERE COLUMN_NAME LIKE '%ID%';

If you want to combine the searches of many schemas into one output result, then you could do this:

SELECT DISTINCT
  'SCHEMA1' AS SCHEMA_NAME
 ,TABLE_NAME
FROM SCHEMA1.COLS
WHERE COLUMN_NAME LIKE '%ID%'
UNION
SELECT DISTINCT
  'SCHEMA2' AS SCHEMA_NAME
 ,TABLE_NAME
FROM SCHEMA2.COLS
WHERE COLUMN_NAME LIKE '%ID%'

In case you'd like to paste windows path from other source (say, File Explorer) - you can do so via input() call in python console:

>>> input()
D:\EP\stuff\1111\this_is_a_long_path\you_dont_want\to_type\or_edit_by_hand
'D:\\EP\\stuff\\1111\\this_is_a_long_path\\you_dont_want\\to_type\\or_edit_by_hand'

Then just copy the result

http://bluerobot.com/web/css/center1.html

body {
    margin:50px 0; 
    padding:0;
    text-align:center;
}

#Content {
    width:500px;
    margin:0 auto;
    text-align:left;
    padding:15px;
    border:1px dashed #333;
    background-color:#eee;
}

I think you can use the nrows parameter. From the docs:

nrows : int, default None

    Number of rows of file to read. Useful for reading pieces of large files

which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):

In [1]: import pandas as pd

In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s

In [3]: len(z)
Out[3]: 20

In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s

Python 2, using lambda

>>> head, tail = (lambda lst: (lst[0], lst[1:]))([1, 1, 2, 3, 5, 8, 13, 21, 34, 55])
>>> head
1
>>> tail
[1, 2, 3, 5, 8, 13, 21, 34, 55]

Sorry guys, I'm a little late to the party but for anyone that stumbles across this question at a later date, I've found the easiest way to do this in a stored procedure is to:

1. Create a new query with any procedure parameters declared and initialised at the top.
2. Paste in the body of your procedure.
3. Add a good old fashioned select query immediately after your table variable is initialised with data.
4. If 3. is not the last statement in the procedure, set a breakpoint on the same line, start debugging and continue straight to your breakpoint.
5. Profit!!

messi19's answer should be the accepted one IMHO, since it is simpler than mine and does the job most of the time, but if you're like me and have a table variable inside a loop that you want to inspect, this does the job nicely without too much effort or external SSMS plugins.

Sure!

#file  -- test.py --
myvar = 42
def test_func():
    print("Hello!")

Now, this file ("test.py") is in python terminology a "module". We can import it (as long as it can be found in our PYTHONPATH) Note that the current directory is always in PYTHONPATH, so if use_test is being run from the same directory where test.py lives, you're all set:

#file -- use_test.py --
import test
test.test_func()  #prints "Hello!"
print (test.myvar)  #prints 42

from test import test_func #Only import the function directly into current namespace
test_func() #prints "Hello"
print (myvar)     #Exception (NameError)

from test import *
test_func() #prints "Hello"
print(myvar)      #prints 42

There's a lot more you can do than just that through the use of special __init__.py files which allow you to treat multiple files as a single module), but this answers your question and I suppose we'll leave the rest for another time.

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Working example

Here's my solution to the problem without using eval. Works with Python2 and Python3. It doesn't work with negative numbers.

$ python -m pytest test.py

test.py

from solution import Solutions

class SolutionsTestCase(unittest.TestCase):
    def setUp(self):
        self.solutions = Solutions()

    def test_evaluate(self):
        expressions = [
            '2+3=5',
            '6+4/2*2=10',
            '3+2.45/8=3.30625',
            '3**3*3/3+3=30',
            '2^4=6'
        ]
        results = [x.split('=')[1] for x in expressions]
        for e in range(len(expressions)):

You can only manually delete properties of objects. Thus:

var container = {};

container.instance = new class();

delete container.instance;

However, this won't work on any other pointers. Therefore:

var container = {};

container.instance = new class();

var pointer = container.instance;

delete pointer; // false ( ie attempt to delete failed )

Furthermore:

delete container.instance; // true ( ie attempt to delete succeeded, but... )

pointer; // class { destroy: function(){} }

So in practice, deletion is only useful for removing object properties themselves, and is not a reliable method for removing the code they point to from memory.

A manually specified destroy method could unbind any event listeners. Something like:

function class(){
  this.properties = { /**/ }

  function handler(){ /**/ }

  something.addEventListener( 'event', handler, false );

  this.destroy = function(){
    something.removeEventListener( 'event', handler );
  }
}

SQL Server is not case sensitive. SELECT * FROM SomeTable is the same as SeLeCT * frOM soMetaBLe.

As has already been stated, you can use:

&& style

lemons && document.write("foo gave me a bar");  

or

bracket-less style

if (lemons) document.write("foo gave me a bar");

short-circuit return

If, however, you wish to use the one line if statement to short-circuit a function though, you'd need to go with the bracket-less version like so:

if (lemons) return "foo gave me a bar";

as

lemons && return "foo gave me a bar"; // does not work!

will give you a SyntaxError: Unexpected keyword 'return'

If you need this code in several places then I'd suggest that you add a short function to keep your code simpler and easier to test.

function add_days( $days, $from_date = null ) {
    if ( is_numeric( $from_date ) ) { 
        $new_date = $from_date; 
    } else { 
        $new_date = time();
    }

    // Timestamp is the number of seconds since an event in the past
    // To increate the value by one day we have to add 86400 seconds to the value
    // 86400 = 24h * 60m * 60s
    $new_date += $days * 86400;

    return $new_date;
}

Then you can use it anywhere like this:

$today       = add_days( 0 );
$tomorrow    = add_days( 1 );
$yesterday   = add_days( -1 );
$in_36_hours = add_days( 1.5 );

$first_reminder  = add_days( 10 );
$second_reminder = add_days( 5, $first_reminder );
$last_reminder   = add_days( 3, $second_reminder );

Time. .Now includes the 09:23:12 or whatever; .Today is the date-part only (at 00:00:00 on that day).

So use .Now if you want to include the time, and .Today if you just want the date!

.Today is essentially the same as .Now.Date

Difficult question to answer - as with most technology solutions, it really depends on your situation and since you have not described the problem you are trying to solve, how can anyone propose a solution?

You need to test them both to see which of them satisfied your needs.

With that said, MongoDB does not require any expensive hardware. Like any other database solution, it will work better with more CPU and memory but is certainly not a requirement - especially for early development purposes.

To keep the branching clean, you could do this:

git checkout newbranch
git branch newbranch2
git reset --hard <commit Id> # the commit at which you want to merge
git checkout master
git merge newbranch
git checkout newbranch2

This way, newbranch will end where it was merged into master, and you continue working on newbranch2.

json.dump() will preserve the ordder of your dictionary. Open the file in a text editor and you will see. It will preserve the order regardless of whether you send it an OrderedDict.

But json.load() will lose the order of the saved object unless you tell it to load into an OrderedDict(), which is done with the object_pairs_hook parameter as J.F.Sebastian instructed above.

It would otherwise lose the order because under usual operation, it loads the saved dictionary object into a regular dict and a regular dict does not preserve the oder of the items it is given.

Use the --force (-f) flag on your mysql import. Rather than stopping on the offending statement, MySQL will continue and just log the errors to the console.

For example:

mysql -u userName -p -f -D dbName < script.sql

If you code on Laravel just use Illuminate\Support\Str

here is example

Str::words($category->publication->title, env('WORDS_COUNT_HOME'), '...')

Hope this was helpful.

You can declare as many Exceptions as you want for your interface method. But the class you gave in your question is invalid. It should read

public class MyClass implements MyInterface {
  public void find(int x) throws A_Exception, B_Exception{
    ----
    ----
    ---
  }
}

Then an interface would look like this

public interface MyInterface {
  void find(int x) throws A_Exception, B_Exception;
}

I had the same problem when I install python3.5.3. And finally I find the pip.exe in this folder: ~/python/scripts/pip.exe. Hope that help.

Only "pre" tag:

<pre>Name:      Waleed Hasees
Age:        33y
Address:    Palestine / Jein</pre>

You can apply any CSS class on this tag.

Excel 2010 saves an UTF-16/UCS-2 TSV file, if you select File > Save As > Unicode Text (.txt). It's (force) suffixed ".txt", which you can change to ".tsv".

If you need CSV, you can then convert the TSV file in a text editor like Notepad++, Ultra Edit, Crimson Editor etc, replacing tabs by semi-colons, commas or the like. Note that e.g. for reading into a DB table, often TSV works fine already (and it is often easier to read manually).

If you need a different code page like UTF-8, use one of the above mentioned editors for converting.

You should adhere your application to the XDG Base Directory Specification. Most answers here are either obsolete or wrong.

Your application should store and load data and configuration files to/from the directories pointed by the following environment variables:

• $XDG_DATA_HOME (default: "$HOME/.local/share"): user-specific data files.
• $XDG_CONFIG_HOME (default: "$HOME/.config"): user-specific configuration files.
• $XDG_DATA_DIRS (default: "/usr/local/share/:/usr/share/"): precedence-ordered set of system data directories.
• $XDG_CONFIG_DIRS (default: "/etc/xdg"): precedence-ordered set of system configuration directories.
• $XDG_CACHE_HOME (default: "$HOME/.cache"): user-specific non-essential data files.

You should first determine if the file in question is:

1. A configuration file ($XDG_CONFIG_HOME:$XDG_CONFIG_DIRS);
2. A data file ($XDG_DATA_HOME:$XDG_DATA_DIRS); or
3. A non-essential (cache) file ($XDG_CACHE_HOME).

It is recommended that your application put its files in a subdirectory of the above directories. Usually, something like $XDG_DATA_DIRS/<application>/filename or $XDG_DATA_DIRS/<vendor>/<application>/filename.

When loading, you first try to load the file from the user-specific directories ($XDG_*_HOME) and, if failed, from system directories ($XDG_*_DIRS). When saving, save to user-specific directories only (since the user probably won't have write access to system directories).

For other, more user-oriented directories, refer to the XDG User Directories Specification. It defines directories for the Desktop, downloads, documents, videos, etc.

req.query will return a JS object after the query string is parsed.

/user?name=tom&age=55 - req.query would yield {name:"tom", age: "55"}

req.params will return parameters in the matched route. If your route is /user/:id and you make a request to /user/5 - req.params would yield {id: "5"}

req.param is a function that peels parameters out of the request. All of this can be found here.

UPDATE

If the verb is a POST and you are using bodyParser, then you should be able to get the form body in you function with req.body. That will be the parsed JS version of the POSTed form.

In the case where you have multiple variables containing the arguments for a command you're running, and not just a single string, you should not use eval directly, as it will fail in the following case:

function echo_arguments() {
  echo "Argument 1: $1"
  echo "Argument 2: $2"
  echo "Argument 3: $3"
  echo "Argument 4: $4"
}

# Note we are passing 3 arguments to `echo_arguments`, not 4
eval echo_arguments arg1 arg2 "Some arg"

Result:

Argument 1: arg1
Argument 2: arg2
Argument 3: Some
Argument 4: arg

Note that even though "Some arg" was passed as a single argument, eval read it as two.

Instead, you can just use the string as the command itself:

# The regular bash eval works by jamming all its arguments into a string then
# evaluating the string. This function treats its arguments as individual
# arguments to be passed to the command being run.
function eval_command() {
  "$@";
}

Note the difference between the output of eval and the new eval_command function:

eval_command echo_arguments arg1 arg2 "Some arg"

Result:

Argument 1: arg1
Argument 2: arg2
Argument 3: Some arg
Argument 4:

If you are using ASP.NET then you can use

yourControlName.Focus()

in the code on the server, which will add appropriate JavaScript into the page.

Other server-side frameworks may have an equivalent method.

Logical indexing is very R-ish. Try:

 x[ x$A ==5 & x$B==4.25 & x$C==4.5 , ] 

Or:

subset( x, A ==5 & B==4.25 & C==4.5 )

I needed month-difference with precision. Although Zane Bien's solution is in the right direction, his second and third examples give inaccurate results. A day in February divided by the number of days in February is not equal to a day in May divided by the number of days in May. So the second example should output ((31-5+1)/31 + 13/30 = ) 1.3043 and the third example ((29-27+1)/29 + 2/30 + 3 = ) 3.1701.

I ended up with the following query:

SELECT
    '2012-02-27' AS startdate,
    '2012-06-02' AS enddate,
    TIMESTAMPDIFF(DAY, (SELECT startdate), (SELECT enddate)) AS days,
    IF(MONTH((SELECT startdate)) = MONTH((SELECT enddate)), 0, (TIMESTAMPDIFF(DAY, (SELECT startdate), LAST_DAY((SELECT startdate)) + INTERVAL 1 DAY)) / DAY(LAST_DAY((SELECT startdate)))) AS period1,     
    TIMESTAMPDIFF(MONTH, LAST_DAY((SELECT startdate)) + INTERVAL 1 DAY, LAST_DAY((SELECT enddate))) AS period2,
    IF(MONTH((SELECT startdate)) = MONTH((SELECT enddate)), (SELECT days), DAY((SELECT enddate))) / DAY(LAST_DAY((SELECT enddate))) AS period3,
    (SELECT period1) + (SELECT period2) + (SELECT period3) AS months

@wdavo is correct. The same is also true for functions.

If you override a base function, like Update, then in your subclass you need:

new void Update()
{
  //do stufff
}

Without the new at the start of the function decleration you will get the warning flag.

If anyone needs the JS code for calculating the trendline of many points on a graph, here's what worked for us in the end:

    const xySum = data.reduce((acc, item) => {_x000D_
        const xy = item.x * item.y_x000D_
        acc += xy_x000D_
        return acc_x000D_
    }, 0)_x000D_
    const xSum = data.reduce((acc, item) => {_x000D_
        acc += item.x_x000D_
        return acc_x000D_
    }, 0)_x000D_
    const ySum = data.reduce((acc, item) => {_x000D_
        acc += item.y_x000D_
        return acc_x000D_
    }, 0)_x000D_
    const aTop = (data.length * xySum) - (xSum * ySum)_x000D_
    const xSquaredSum = data.reduce((acc, item) => {_x000D_
        const xSquared = item.x * item.x_x000D_
        acc += xSquared_x000D_
        return acc_x000D_
    }, 0)_x000D_
    const aBottom = (data.length * xSquaredSum) - (xSum * xSum)_x000D_
    const a = aTop / aBottom_x000D_
    const bTop = ySum - (a * xSum)_x000D_
    const b = bTop / data.length_x000D_
    return function trendline(x) {_x000D_
        return a * x + b_x000D_
    }_x000D_
}

It takes an array of (x,y) points and returns the function of a y given a certain x Have fun :)

I think best method is to query pg_setting view:

 select s.name, s.setting, s.short_desc from pg_settings s where s.name='data_directory';

Output:

      name      |        setting         |            short_desc
----------------+------------------------+-----------------------------------
 data_directory | /var/lib/pgsql/10/data | Sets the server's data directory.

Native way to get the mimetype:

For PHP < 5.3 use mime_content_type()
For PHP >= 5.3 use finfo_open() or mime_content_type()

Alternatives to get the MimeType are exif_imagetype and getimagesize, but these rely on having the appropriate libs installed. In addition, they will likely just return image mimetypes, instead of the whole list given in magic.mime.

While mime_content_type is available from PHP 4.3 and is part of the FileInfo extension (which is enabled by default since PHP 5.3, except for Windows platforms, where it must be enabled manually, for details see here).

If you don't want to bother about what is available on your system, just wrap all four functions into a proxy method that delegates the function call to whatever is available, e.g.

function getMimeType($filename)
{
    $mimetype = false;
    if(function_exists('finfo_open')) {
        // open with FileInfo
    } elseif(function_exists('getimagesize')) {
        // open with GD
    } elseif(function_exists('exif_imagetype')) {
       // open with EXIF
    } elseif(function_exists('mime_content_type')) {
       $mimetype = mime_content_type($filename);
    }
    return $mimetype;
}

./script.sh | sort -u

This is the same as monoxide's answer, but a bit more concise.

The 1s are because everything is perfectly correlated with itself, and the NAs are because there are NAs in your variables.

You will have to specify how you want R to compute the correlation when there are missing values, because the default is to only compute a coefficient with complete information.

You can change this behavior with the use argument to cor, see ?cor for details.

Since posting my original answer, I found that split is a very easy to use node module for line reading in a file; Which also accepts optional parameters.

var split = require('split');
fs.createReadStream(file)
    .pipe(split())
    .on('data', function (line) {
      //each chunk now is a seperate line! 
    });

Haven't tested on very large files. Let us know if you do.

SELECT
    t1.*

FROM
    table_name AS t1

    LEFT JOIN table_name AS t2 ON (
        t2.group_by_column = t1.group_by_column
        -- group_by_column is the column you would use in the GROUP BY statement
        AND
        t2.order_by_column < t1.order_by_column
        -- order_by_column is column you would use in the ORDER BY statement
        -- usually is the autoincremented key column
    )

WHERE
    t2.group_by_column IS NULL;

With MySQL v8+ you could use window functions

You can create a DAO method to do this.

@Dao 
interface MyDao {
    @Query("DELETE FROM myTableName")
    public void nukeTable();
}

If you want to do it in plain javascript, you can define a function like this:

var getJSON = function(url, callback) {
    var xhr = new XMLHttpRequest();
    xhr.open('GET', url, true);
    xhr.responseType = 'json';
    xhr.onload = function() {
      var status = xhr.status;
      if (status === 200) {
        callback(null, xhr.response);
      } else {
        callback(status, xhr.response);
      }
    };
    xhr.send();
};

And use it like this:

getJSON('http://query.yahooapis.com/v1/public/yql?q=select%20%2a%20from%20yahoo.finance.quotes%20WHERE%20symbol%3D%27WRC%27&format=json&diagnostics=true&env=store://datatables.org/alltableswithkeys&callback',
function(err, data) {
  if (err !== null) {
    alert('Something went wrong: ' + err);
  } else {
    alert('Your query count: ' + data.query.count);
  }
});

Note that data is an object, so you can access its attributes without having to parse it.

try this code

DataRow foundRow = FinalDt.Rows.Find(Value);

but set at lease one primary key

I am using python3 and found out that you need to encode your string before you can pass it into stdin:

p = Popen(['grep', 'f'], stdout=PIPE, stdin=PIPE, stderr=PIPE)
out, err = p.communicate(input='one\ntwo\nthree\nfour\nfive\nsix\n'.encode())
print(out)

In codeigniter you can't pass parameters in the url as you are doing in core php.So remove the "?" and "product_id" and simply pass the id.If you want more security you can encrypt the id and pass it.

Here is an answer to the literal meaning of the title rather than the body of this question:

import time
import datetime
import random

def date_to_timestamp(d) :
  return int(time.mktime(d.timetuple()))

def randomDate(start, end):
  """Get a random date between two dates"""

  stime = date_to_timestamp(start)
  etime = date_to_timestamp(end)

  ptime = stime + random.random() * (etime - stime)

  return datetime.date.fromtimestamp(ptime)

This code is based loosely on the accepted answer.

Just do one thing, We need to set the name property for the same types. for eg.

Try below:

<form>
    <div id="group1">
        <input type="radio" value="val1" name="group1">
        <input type="radio" value="val2" name="group1">
    </div>
</form>

And also we can do it in angular1,angular 2 or in jquery also.

<div *ngFor="let option of question.options; index as j">
<input type="radio" name="option{{j}}" value="option{{j}}" (click)="checkAnswer(j+1)">{{option}}
</div>  

You can use jquery.form.js plugin to upload image via ajax to the server.

http://malsup.com/jquery/form/

Here is the sample jQuery ajax image upload script

(function() {
$('form').ajaxForm({
    beforeSubmit: function() {  
        //do validation here


    },

    beforeSend:function(){
       $('#loader').show();
       $('#image_upload').hide();
    },
    success: function(msg) {

        ///on success do some here
    }
}); })();  

If you have any doubt, please refer following ajax image upload tutorial here

I am using this Temporary Solution:

import {Pipe, PipeTransform} from "angular2/core";
import {DateFormatter} from 'angular2/src/facade/intl';

@Pipe({
    name: 'dateFormat'
})
export class DateFormat implements PipeTransform {
    transform(value: any, args: string[]): any {
        if (value) {
            var date = value instanceof Date ? value : new Date(value);
            return DateFormatter.format(date, 'pt', 'dd/MM/yyyy');
        }
    }
}

there are mainly three options are possible for mapping purpose

1. serialize
2. XML mapping
3. POJO mapping.(Plain Old Java Objects)

While using the pojo classes,it is easy for a developer to map with the database. POJO classes are created for database and at the same time value-objects classes are created with getter and setter methods that will easily hold the content.

So,for the purpose of mapping in between java with database, value-objects and POJO classes are implemented.

If you need to include non-ASCII alphabetic characters, and if your regex flavor supports Unicode, then

\A\pL+\z

would be the correct regex.

Some regex engines don't support this Unicode syntax but allow the \w alphanumeric shorthand to also match non-ASCII characters. In that case, you can get all alphabetics by subtracting digits and underscores from \w like this:

\A[^\W\d_]+\z

\A matches at the start of the string, \z at the end of the string (^ and $ also match at the start/end of lines in some languages like Ruby, or if certain regex options are set).

If the content is appended after .on() is called, you'll need to create a delegated event on a parent element of the loaded content. This is because event handlers are bound when .on() is called (i.e. usually on page load). If the element doesn't exist when .on() is called, the event will not be bound to it!

Because events propagate up through the DOM, we can solve this by creating a delegated event on a parent element (.parent-element in the example below) that we know exists when the page loads. Here's how:

$('.parent-element').on('click', '.mylink', function(){
  alert ("new link clicked!");
})

Some more reading on the subject:

• http://jqfundamentals.com/chapter/events

If you have several threads executing the methods m1 and m2 in the code below:

class SomeClass {
    private int i = 0;

    public void m1() { i = 5; }
    public int m2() { return i; }
}

you have the guarantee that any thread calling m2 will either read 0 or 5.

On the other hand, with this code (where i is a long):

class SomeClass {
    private long i = 0;

    public void m1() { i = 1234567890L; }
    public long m2() { return i; }
}

a thread calling m2 could read 0, 1234567890L, or some other random value because the statement i = 1234567890L is not guaranteed to be atomic for a long (a JVM could write the first 32 bits and the last 32 bits in two operations and a thread might observe i in between).

Sure. Just list the files:

$ svn ci -m "Fixed all those horrible crashes" foo bar baz graphics/logo.png

I'm not aware of a way to tell it to ignore a certain set of files. Of course, if the files you do want to commit are easily listed by the shell, you can use that:

$ svn ci -m "No longer sets printer on fire" printer-driver/*.c

You can also have the svn command read the list of files to commit from a file:

$ svn ci -m "Now works" --targets fix4711.txt

As mentioned in the error, the official manual and the comments:

Replace

public function TSStatus($host, $queryPort)

with

public function __construct($host, $queryPort)

You can use grep to get the byte-offset of the matching part of a string:

echo $str | grep -b -o str

As per your example:

[user@host ~]$ echo "The cat sat on the mat" | grep -b -o cat
4:cat

you can pipe that to awk if you just want the first part

echo $str | grep -b -o str | awk 'BEGIN {FS=":"}{print $1}'

You can create one more class naming

.flex-control-thumbs-without-width li {
width: auto;
float: initial; or none
}

Add this class whenever you need to override like below,

<li class="flex-control-thumbs flex-control-thumbs-without-width"> </li>

And do remove whenever you don't need for other <li>

I know this is old, but I just solved it with this:

  var update_size = function() {
    $(oTable).css({ width: $(oTable).parent().width() });
    oTable.fnAdjustColumnSizing();  
  }

  $(window).resize(function() {
    clearTimeout(window.refresh_size);
    window.refresh_size = setTimeout(function() { update_size(); }, 250);
  });

Note: This answer applies to DataTables 1.9

You can find answer in depth here.

But in general with float you need to be aware and take care of the surrounding elements and inline-block simple way to line elements.

Thanks

You can use // MARK:

There has also been discussion that liberal use of class extensions might be a better practice anyway. Since extensions can implement protocols, you can e.g. put all of your table view delegate methods in an extension and group your code at a more semantic level than #pragma mark is capable of.

If I understand the goal is to insert a new record to a table but if the data is already on the table: skip it! Here is my answer:

INSERT INTO tbl_member 
(Field1,Field2,Field3,...) 
SELECT a.Field1,a.Field2,a.Field3,... 
FROM (SELECT Field1 = [NewValueField1], Field2 = [NewValueField2], Field3 = [NewValueField3], ...) AS a 
LEFT JOIN tbl_member AS b 
ON a.Field1 = b.Field1 
WHERE b.Field1 IS NULL

The record to be inserted is in the new value fields.

Integer.parseInt(str) throws NumberFormatException if the string does not contain a parsable integer. You can hadle the same as below.

int a;
String str = "N/A";

try {   
   a = Integer.parseInt(str);
} catch (NumberFormatException nfe) {
  // Handle the condition when str is not a number.
}

<hr width="50%">

This creates a horizontal line with a width of 50%, you would need to create/modify the class if you would like to edit the style.

I am aware there are already several answers, but I added this, as this adds substantial information about the decimal places and hence the asked maximum length.

The length of latitude and langitude depend on precision. The absolute maximum length for each is:

• Latitude: 12 characters (example: -90.00000001)
• Longitude: 13 characters (example: -180.00000001)

For both holds: a maximum of 8 decial places is possible (though not commonly used).

Explanation for the dependency on precision:

Use imagesLoaded PACKAGED v3.1.8 (6.8 Kb when minimized). It is relatively old (since 2010) but still active project.

You can find it on github: https://github.com/desandro/imagesloaded

Their official site: http://imagesloaded.desandro.com/

Why it is better than using:

$(window).load() 

Because you may want to load images dynamically, like this: jsfiddle

$('#button').click(function(){
    $('#image').attr('src', '...');
});

Using a check for newkey!=oldkey, this way you can do:

if newkey!=oldkey:  
    dictionary[newkey] = dictionary[oldkey]
    del dictionary[oldkey]

This does not require a HTML entity if you are using a modern encoding (such as UTF-8). And if you're not already, you probably should be.

To avoid this sort of trouble, you can use replace (which takes a plain string) instead of replaceAll (which takes a regular expression). You will still need to escape backslashes, but not in the wild ways required with regular expressions.

In my case... with MySQL:

SELECT ... GROUP BY TIMESTAMPADD(HOUR, HOUR(columName), DATE(columName))

This approach fixed the problem for me.

Try this:

try this

Execute this SQL:

SHOW TABLE STATUS LIKE '<tablename>'

and fetch the value of the field Auto_increment

I would simply write each line to a file, since it's already in a CSV format:

write_file = "output.csv"
with open(write_file, "w") as output:
    for line in text:
        output.write(line + '\n')

I can't recall how to write lines with line-breaks at the moment, though :p

Also, you might like to take a look at this answer about write(), writelines(), and '\n'.

first of all, item should be removed from the list!

  mDataSet.remove(getAdapterPosition());

then:

  notifyItemRemoved(getAdapterPosition());
  notifyItemRangeChanged(getAdapterPosition(),mDataSet.size());

On your MainForm make a function to set the textbox the checks the InvokeRequired

public void AppendTextBox(string value)
{
    if (InvokeRequired)
    {
        this.Invoke(new Action<string>(AppendTextBox), new object[] {value});
        return;
    }
    ActiveForm.Text += value;
}

although in your static method you can't just call.

WindowsFormsApplication1.Form1.AppendTextBox("hi. ");

you have to have a static reference to the Form1 somewhere, but this isn't really recommended or necessary, can you just make your SampleFunction not static if so then you can just call

AppendTextBox("hi. ");

It will append on a differnt thread and get marshalled to the UI using the Invoke call if required.

Full Sample

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        new Thread(SampleFunction).Start();
    }

    public void AppendTextBox(string value)
    {
        if (InvokeRequired)
        {
            this.Invoke(new Action<string>(AppendTextBox), new object[] {value});
            return;
        }
        textBox1.Text += value;
    }

    void SampleFunction()
    {
        // Gets executed on a seperate thread and 
        // doesn't block the UI while sleeping
        for(int i = 0; i<5; i++)
        {
            AppendTextBox("hi.  ");
            Thread.Sleep(1000);
        }
    }

To retrieve your image from byte to base64 string....

IN view:

My best guess at why you had problems with the ----- covering your first result is that you actually read the input line from a file. That line probably had a \r on the end so you ended up with something like this:

-----------test2-------test3

What happened is the machine actually printed this:

test-------test2-------test3\r-------

That means, because of the carriage return at the end of test3, that the dashes after test3 were printed over the top of the first word (and a few of the existing dashes between test and test2 but you wouldn't notice that because they were already dashes).

if you want to get just previous month, then you can use as like following

$prevmonth = date('M Y', strtotime('-1 months'));

if you want to get same days of previous month, Then you can use as like following ..

$prevmonth = date('M Y d', strtotime('-1 months'));

if you want to get last date of previous month , Then you can use as like following ...

$prevmonth = date('M Y t', strtotime('-1 months'));

if you want to get first date of previous month , Then you can use as like following ...

$prevmonth = date('M Y 1', strtotime('-1 months'));

I was able to fix my problem by using a combination of $.ajaxSetup and appending a timestamp to the url of my post (not to the post parameters/body). This based on the recommendations of previous answers

$(document).ready(function(){
    $.ajaxSetup({ type:'POST', headers: {"cache-control","no-cache"}});

    $('#myForm').submit(function() {
        var data = $('#myForm').serialize();
        var now = new Date();
        var n = now.getTime();
        $.ajax({
            type: 'POST',
            url: 'myendpoint.cfc?method=login&time='+n,
            data: data,
            success: function(results){
                if(results.success) {
                    window.location = 'app.cfm';
                } else {
                    console.log(results);
                    alert('login failed');
                }
            }
        });
    });
});

In my case I opened a pop up window on click on linkbutton in parent page. To refresh parent on closing child using

window.opener.location.reload();

in child window caused re open the child window (Might be because of View State I guess. Correct me If I m wrong). So I decided not to reload page in parent and load the the page again assigning same url to it.

To avoid popup opening again after closing pop up window this might help,

window.onunload = function(){
    window.opener.location = window.opener.location;};

brew install ffmpeg will install what you need and all the dependencies if you are on a Mac.

If you give the following command you'll get the list of activities including commits, merges.

git reflog

Your last commit should probably be at 'HEAD@{0}'. You can check the same with your commit message. To go to that point, use the command

git reset --hard 'HEAD@{0}'

Your merge will be reverted. If in case you have new files left, discard those changes from the merge.

I know this is a super old post, but I figured this may still be helpful.

If you're comfortable with reading json format you could replace your var_dump with:

return json_encode($myvar);

I've been using this to help troubleshoot a service I've been building that has some deeply nested arrays. This will return every level of your array without truncating anything or requiring you to change your php.ini file.

Also, because the json_encoded data is a string it means you can write it to the error log easily

error_log(json_encode($myvar));

It probably isn't the best choice for every situation, but it's a choice!

Don't use systemPath. Contrary to what people have said here, you can put an external jar in a folder under your checked-out project directory and haven Maven find it like other dependencies. Here are two crucial steps:

1. Use "mvn install:install-file" with -DlocalRepositoryPath.
2. Configure a repository to point to that path in your POM.

It is fairly straightforward and you can find a step-by-step example here: http://randomizedsort.blogspot.com/2011/10/configuring-maven-to-use-local-library.html

If you have made that request in your application already, and see it logged in Google Dev Tools, you can use the copy cURL command from the context menu when right-clicking on the request in the network tab. Copy -> Copy as cURL. It will contain all headers, cookies, etc..

Use .blur().

The blur event is sent to an element when it loses focus. Originally, this event was only applicable to form elements, such as <input>. In recent browsers, the domain of the event has been extended to include all element types. An element can lose focus via keyboard commands, such as the Tab key, or by mouse clicks elsewhere on the page.

$("#myInputID").blur(); 

I recently used Spring Security 3.0 for this (combined with Wicket btw), and am quite happy with it. Here's a good thorough tutorial and documentation. Also take a look at this tutorial which gives a good explanation of the hashing/salting/decoding setup for Spring Security 2.

If you have data that has HTML tags and you want to display it so that a person can SEE the tags, use HttpServerUtility::HtmlEncode.

If you have data that has HTML tags in it and you want the user to see the tags rendered, then display the text as is. If the text represents an entire web page, use an IFRAME for it.

If you have data that has HTML tags and you want to strip out the tags and just display the unformatted text, use a regular expression.

You may try this:-

Scanner scan = new Scanner(System.in);
System.out.println("Type a sentence and press enter.");
String input = scan.nextLine();
String strippedInput = input.replaceAll("\\W", "");
System.out.println("Your string: " + strippedInput);

[^\w] matches a non-word character, so the above regular expression will match and remove all non-word characters.

The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.

According to this Google blogpost:

It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.

When referencing the mipmap- folders ensure you are using the following reference:

android:icon="@mipmap/ic_launcher"

The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.

It checks to see whether the specific object is contained in the list.

You might be better using the Find method on the list.

Here's an example

List<CartProduct> lst = new List<CartProduct>();

CartProduct objBeer;
objBeer = lst.Find(x => (x.Name == "Beer"));

Hope that helps

You should also look at LinQ - overkill for this perhaps, but a useful tool nonetheless...

<TL;DR> The problem is rather simple, actually: you are not matching the declared encoding (in the XML declaration) with the datatype of the input parameter. If you manually added <?xml version="1.0" encoding="utf-8"?><test/> to the string, then declaring the SqlParameter to be of type SqlDbType.Xml or SqlDbType.NVarChar would give you the "unable to switch the encoding" error. Then, when inserting manually via T-SQL, since you switched the declared encoding to be utf-16, you were clearly inserting a VARCHAR string (not prefixed with an upper-case "N", hence an 8-bit encoding, such as UTF-8) and not an NVARCHAR string (prefixed with an upper-case "N", hence the 16-bit UTF-16 LE encoding).

The fix should have been as simple as:

1. In the first case, when adding the declaration stating encoding="utf-8": simply don't add the XML declaration.
2. In the second case, when adding the declaration stating encoding="utf-16": either
   1. simply don't add the XML declaration, OR
   2. simply add an "N" to the input parameter type: SqlDbType.NVarChar instead of SqlDbType.VarChar :-) (or possibly even switch to using SqlDbType.Xml)

(Detailed response is below)

All of the answers here are over-complicated and unnecessary (regardless of the 121 and 184 up-votes for Christian's and Jon's answers, respectively). They might provide working code, but none of them actually answer the question. The issue is that nobody truly understood the question, which ultimately is about how the XML datatype in SQL Server works. Nothing against those two clearly intelligent people, but this question has little to nothing to do with serializing to XML. Saving XML data into SQL Server is much easier than what is being implied here.

It doesn't really matter how the XML is produced as long as you follow the rules of how to create XML data in SQL Server. I have a more thorough explanation (including working example code to illustrate the points outlined below) in an answer on this question: How to solve “unable to switch the encoding” error when inserting XML into SQL Server, but the basics are:

1. The XML declaration is optional
2. The XML datatype stores strings always as UCS-2 / UTF-16 LE
3. If your XML is UCS-2 / UTF-16 LE, then you:
   1. pass in the data as either NVARCHAR(MAX) or XML / SqlDbType.NVarChar (maxsize = -1) or SqlDbType.Xml, or if using a string literal then it must be prefixed with an upper-case "N".
   2. if specifying the XML declaration, it must be either "UCS-2" or "UTF-16" (no real difference here)
4. If your XML is 8-bit encoded (e.g. "UTF-8" / "iso-8859-1" / "Windows-1252"), then you:
   1. need to specify the XML declaration IF the encoding is different than the code page specified by the default Collation of the database
   2. you must pass in the data as VARCHAR(MAX) / SqlDbType.VarChar (maxsize = -1), or if using a string literal then it must not be prefixed with an upper-case "N".
   3. Whatever 8-bit encoding is used, the "encoding" noted in the XML declaration must match the actual encoding of the bytes.
   4. The 8-bit encoding will be converted into UTF-16 LE by the XML datatype

With the points outlined above in mind, and given that strings in .NET are always UTF-16 LE / UCS-2 LE (there is no difference between those in terms of encoding), we can answer your questions:

Is there a reason why I shouldn't use StringWriter to serialize an Object when I need it as a string afterwards?

No, your StringWriter code appears to be just fine (at least I see no issues in my limited testing using the 2nd code block from the question).

Wouldn't setting the encoding to UTF-16 (in the xml tag) work then?

It isn't necessary to provide the XML declaration. When it is missing, the encoding is assumed to be UTF-16 LE if you pass the string into SQL Server as NVARCHAR (i.e. SqlDbType.NVarChar) or XML (i.e. SqlDbType.Xml). The encoding is assumed to be the default 8-bit Code Page if passing in as VARCHAR (i.e. SqlDbType.VarChar). If you have any non-standard-ASCII characters (i.e. values 128 and above) and are passing in as VARCHAR, then you will likely see "?" for BMP characters and "??" for Supplementary Characters as SQL Server will convert the UTF-16 string from .NET into an 8-bit string of the current Database's Code Page before converting it back into UTF-16 / UCS-2. But you shouldn't get any errors.

On the other hand, if you do specify the XML declaration, then you must pass into SQL Server using the matching 8-bit or 16-bit datatype. So if you have a declaration stating that the encoding is either UCS-2 or UTF-16, then you must pass in as SqlDbType.NVarChar or SqlDbType.Xml. Or, if you have a declaration stating that the encoding is one of the 8-bit options (i.e. UTF-8, Windows-1252, iso-8859-1, etc), then you must pass in as SqlDbType.VarChar. Failure to match the declared encoding with the proper 8 or 16 -bit SQL Server datatype will result in the "unable to switch the encoding" error that you were getting.

For example, using your StringWriter-based serialization code, I simply printed the resulting string of the XML and used it in SSMS. As you can see below, the XML declaration is included (because StringWriter does not have an option to OmitXmlDeclaration like XmlWriter does), which poses no problem so long as you pass the string in as the correct SQL Server datatype:

-- Upper-case "N" prefix == NVARCHAR, hence no error:
DECLARE @Xml XML = N'<?xml version="1.0" encoding="utf-16"?>
<string>Test ?</string>';
SELECT @Xml;
-- <string>Test ?</string>

As you can see, it even handles characters beyond standard ASCII, given that ? is BMP Code Point U+1234, and is Supplementary Character Code Point U+1F638. However, the following:

-- No upper-case "N" prefix on the string literal, hence VARCHAR:
DECLARE @Xml XML = '<?xml version="1.0" encoding="utf-16"?>
<string>Test ?</string>';

results in the following error:

Msg 9402, Level 16, State 1, Line XXXXX
XML parsing: line 1, character 39, unable to switch the encoding

Ergo, all of that explanation aside, the full solution to your original question is:

You were clearly passing the string in as SqlDbType.VarChar. Switch to SqlDbType.NVarChar and it will work without needing to go through the extra step of removing the XML declaration. This is preferred over keeping SqlDbType.VarChar and removing the XML declaration because this solution will prevent data loss when the XML includes non-standard-ASCII characters. For example:

-- No upper-case "N" prefix on the string literal == VARCHAR, and no XML declaration:
DECLARE @Xml2 XML = '<string>Test ?</string>';
SELECT @Xml2;
-- <string>Test ???</string>

As you can see, there is no error this time, but now there is data-loss 🙀.

I had a similar Problem as @CraigWalker on debian: My database was in a state where a DROP TABLE failed because it couldn't find the table, but a CREATE TABLE also failed because MySQL thought the table still existed. So the broken table still existed somewhere although it wasn't there when I looked in phpmyadmin.

I created this state by just copying the whole folder that contained a database with some MyISAM and some InnoDB tables

cp -a /var/lib/mysql/sometable /var/lib/mysql/test

(this is not recommended!)

All InnoDB tables where not visible in the new database test in phpmyadmin.

sudo mysqladmin flush-tables didn't help either.

My solution: I had to delete the new test database with drop database test and copy it with mysqldump instead:

mysqldump somedatabase -u username -p -r export.sql
mysql test -u username -p < export.sql

I used this and in worked for me!

$("checkbox selector").click(function() {
    if($(this).prop('checked')==true){

    }
});

Use formula =row(b2)-x, where x will adjust the entries so that the first S/No is marked as 1 and will increment with the rows.

You can use COLLATE NOCASE in your SELECT query:

SELECT * FROM ... WHERE name = 'someone' COLLATE NOCASE

Additionaly, in SQLite, you can indicate that a column should be case insensitive when you create the table by specifying collate nocase in the column definition (the other options are binary (the default) and rtrim; see here). You can specify collate nocase when you create an index as well. For example:

create table Test
(
  Text_Value  text collate nocase
);

insert into Test values ('A');
insert into Test values ('b');
insert into Test values ('C');

create index Test_Text_Value_Index
  on Test (Text_Value collate nocase);

Expressions involving Test.Text_Value should now be case insensitive. For example:

sqlite> select Text_Value from Test where Text_Value = 'B';
Text_Value      
----------------
b               

sqlite> select Text_Value from Test order by Text_Value;
Text_Value      
----------------
A               
b               
C    

sqlite> select Text_Value from Test order by Text_Value desc;
Text_Value      
----------------
C               
b               
A               

The optimiser can also potentially make use of the index for case-insensitive searching and matching on the column. You can check this using the explain SQL command, e.g.:

sqlite> explain select Text_Value from Test where Text_Value = 'b';
addr              opcode          p1          p2          p3

You are trying to access the class as opposed to the object. That statement can be confusing to beginners, but you are effectively trying to open your house door by picking up the door on your house plans.

If you actually wanted to access the form components directly from a class (which you don't) you would use the variable that instantiates your form.

Depending on which way you want to go you'd be better of either sending the text of a control or whatever to a method in your classes eg

public void DoSomethingWithText(string formText)
{
   // do something text in here
}

or exposing properties on your form class and setting the form text in there - eg

string SomeProperty
{
   get 
   {
      return textBox1.Text;
   }
   set
   {
      textBox1.Text = value;
   }
}

I assume entropy was mentioned in the context of building decision trees.

To illustrate, imagine the task of learning to classify first-names into male/female groups. That is given a list of names each labeled with either m or f, we want to learn a model that fits the data and can be used to predict the gender of a new unseen first-name.

name       gender
-----------------        Now we want to predict 
Ashley        f              the gender of "Amro" (my name)
Brian         m
Caroline      f
David         m

First step is deciding what features of the data are relevant to the target class we want to predict. Some example features include: first/last letter, length, number of vowels, does it end with a vowel, etc.. So after feature extraction, our data looks like:

# name    ends-vowel  num-vowels   length   gender
# ------------------------------------------------
Ashley        1         3           6        f
Brian         0         2           5        m
Caroline      1         4           8        f
David         0         2           5        m

The goal is to build a decision tree. An example of a tree would be:

length<7
|   num-vowels<3: male
|   num-vowels>=3
|   |   ends-vowel=1: female
|   |   ends-vowel=0: male
length>=7
|   length=5: male

basically each node represent a test performed on a single attribute, and we go left or right depending on the result of the test. We keep traversing the tree until we reach a leaf node which contains the class prediction (m or f)

So if we run the name Amro down this tree, we start by testing "is the length<7?" and the answer is yes, so we go down that branch. Following the branch, the next test "is the number of vowels<3?" again evaluates to true. This leads to a leaf node labeled m, and thus the prediction is male (which I happen to be, so the tree predicted the outcome correctly).

The decision tree is built in a top-down fashion, but the question is how do you choose which attribute to split at each node? The answer is find the feature that best splits the target class into the purest possible children nodes (ie: nodes that don't contain a mix of both male and female, rather pure nodes with only one class).

This measure of purity is called the information. It represents the expected amount of information that would be needed to specify whether a new instance (first-name) should be classified male or female, given the example that reached the node. We calculate it based on the number of male and female classes at the node.

Entropy on the other hand is a measure of impurity (the opposite). It is defined for a binary class with values a/b as:

Entropy = - p(a)*log(p(a)) - p(b)*log(p(b))

This binary entropy function is depicted in the figure below (random variable can take one of two values). It reaches its maximum when the probability is p=1/2, meaning that p(X=a)=0.5 or similarlyp(X=b)=0.5 having a 50%/50% chance of being either a or b (uncertainty is at a maximum). The entropy function is at zero minimum when probability is p=1 or p=0 with complete certainty (p(X=a)=1 or p(X=a)=0 respectively, latter implies p(X=b)=1).

Of course the definition of entropy can be generalized for a discrete random variable X with N outcomes (not just two):

(the log in the formula is usually taken as the logarithm to the base 2)

Back to our task of name classification, lets look at an example. Imagine at some point during the process of constructing the tree, we were considering the following split:

     ends-vowel
      [9m,5f]          <--- the [..,..] notation represents the class
    /          \            distribution of instances that reached a node
   =1          =0
 -------     -------
 [3m,4f]     [6m,1f]

As you can see, before the split we had 9 males and 5 females, i.e. P(m)=9/14 and P(f)=5/14. According to the definition of entropy:

Entropy_before = - (5/14)*log2(5/14) - (9/14)*log2(9/14) = 0.9403

Next we compare it with the entropy computed after considering the split by looking at two child branches. In the left branch of ends-vowel=1, we have:

Entropy_left = - (3/7)*log2(3/7) - (4/7)*log2(4/7) = 0.9852

and the right branch of ends-vowel=0, we have:

Entropy_right = - (6/7)*log2(6/7) - (1/7)*log2(1/7) = 0.5917

We combine the left/right entropies using the number of instances down each branch as weight factor (7 instances went left, and 7 instances went right), and get the final entropy after the split:

Entropy_after = 7/14*Entropy_left + 7/14*Entropy_right = 0.7885

Now by comparing the entropy before and after the split, we obtain a measure of information gain, or how much information we gained by doing the split using that particular feature:

Information_Gain = Entropy_before - Entropy_after = 0.1518

You can interpret the above calculation as following: by doing the split with the end-vowels feature, we were able to reduce uncertainty in the sub-tree prediction outcome by a small amount of 0.1518 (measured in bits as units of information).

At each node of the tree, this calculation is performed for every feature, and the feature with the largest information gain is chosen for the split in a greedy manner (thus favoring features that produce pure splits with low uncertainty/entropy). This process is applied recursively from the root-node down, and stops when a leaf node contains instances all having the same class (no need to split it further).

Note that I skipped over some details which are beyond the scope of this post, including how to handle numeric features, missing values, overfitting and pruning trees, etc..

Please always check your certificate expiry date first because most of the certificates have an expiry date. In my case certificate has expired and I was trying to build project.

Yes, what you are asking for is called AJAX or XMLHttpRequest. You can either use a library like jQuery to simplify making the call (due to cross-browser compatibility issues), or write your own handler.

In jQuery:

$.GET('url.asp', {data: 'here'}, function(data){ /* what to do with the data returned */ })

In plain vanilla javaScript (from w3c):

var xmlhttp;
function loadXMLDoc(url)
{
    xmlhttp=null;
if (window.XMLHttpRequest)
  {// code for all new browsers
      xmlhttp=new XMLHttpRequest();
  }
else if (window.ActiveXObject)
  {// code for IE5 and IE6
      xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
if (xmlhttp!=null)
  {
      xmlhttp.onreadystatechange=state_Change;
      xmlhttp.open("GET",url,true);
      xmlhttp.send(null);
  }
else
  {
      alert("Your browser does not support XMLHTTP.");
  }
}

function state_Change()
{
    if (xmlhttp.readyState==4)
      {// 4 = "loaded"
          if (xmlhttp.status==200)
            {// 200 = OK
             //xmlhttp.data and shtuff
            // ...our code here...
        }
  else
        {
            alert("Problem retrieving data");
        }
  }
}

Get Screenshot From View :

- (UIImage *)takeSnapshotView {
    CGRect rect = [myView bounds];//Here you can change your view with myView
    UIGraphicsBeginImageContextWithOptions(rect.size,YES,0.0f);
    CGContextRef context = UIGraphicsGetCurrentContext();
    [myView.layer renderInContext:context];
    UIImage *capturedScreen = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return capturedScreen;//capturedScreen is the image of your view
}

Hope, this is what you're looking for. Any concern get back to me. :)

You are using the wrong URL (you are using the URL for the html webpage). Try either of these instead:

There are different types of shells. The SSH command execution shell is a non-interactive shell, whereas your normal shell is either a login shell or an interactive shell. Description follows, from man bash:

       A  login  shell  is  one whose first character of argument
       zero is a -, or one started with the --login option.

       An interactive shell is  one  started  without  non-option
       arguments  and  without the -c option whose standard input
       and error are both connected to terminals  (as  determined
       by  isatty(3)), or one started with the -i option.  PS1 is
       set and $- includes i if bash is interactive,  allowing  a
       shell script or a startup file to test this state.

       The  following  paragraphs  describe how bash executes its
       startup files.  If any of the files exist  but  cannot  be
       read,  bash reports an error.  Tildes are expanded in file
       names as described below  under  Tilde  Expansion  in  the
       EXPANSION section.

       When  bash is invoked as an interactive login shell, or as
       a non-interactive shell with the --login option, it  first
       reads and executes commands from the file /etc/profile, if
       that file exists.  After reading that file, it  looks  for
       ~/.bash_profile,  ~/.bash_login,  and  ~/.profile, in that
       order, and reads and executes commands from the first  one
       that  exists  and is readable.  The --noprofile option may
       be used when the shell is started to inhibit  this  behav­
       ior.

       When a login shell exits, bash reads and executes commands
       from the file ~/.bash_logout, if it exists.

       When an interactive shell that is not  a  login  shell  is
       started,  bash reads and executes commands from ~/.bashrc,
       if that file exists.  This may be inhibited by  using  the
       --norc  option.   The --rcfile file option will force bash
       to  read  and  execute  commands  from  file  instead   of
       ~/.bashrc.

       When  bash  is  started  non-interactively, to run a shell
       script, for example, it looks for the variable BASH_ENV in
       the  environment,  expands  its value if it appears there,
       and uses the expanded value as the name of a file to  read
       and  execute.   Bash  behaves  as if the following command
       were executed:
              if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
       but the value of the PATH variable is not used  to  search
       for the file name.

You can add spring-context dependency for spring jars. You will get the following jars along with it.

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>5.0.5.RELEASE</version>
</dependency>

if you also want web components, you can use spring-webmvc dependency.

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>5.0.5.RELEASE</version>
</dependency>

You can use whatever version of that you want. I have used 5.0.5.RELEASE here.

To get the textbox value, you can use the jQuery val() function.

For example,

$('input:textbox').val() – Get textbox value.

$('input:textbox').val("new text message") – Set the textbox value.

With Python3x, you need to convert your string to raw bytes. You would have to encode the string as bytes. Over the network you need to send bytes and not characters. You are right that this would work for Python 2x since in Python 2x, socket.sendto on a socket takes a "plain" string and not bytes. Try this:

print("UDP target IP:", UDP_IP)
print("UDP target port:", UDP_PORT)
print("message:", MESSAGE)

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
sock.sendto(bytes(MESSAGE, "utf-8"), (UDP_IP, UDP_PORT))

setting known host is better than setting fingure print value.

When you set known host, try to manually ssh (very first time, before application runs) from the box the application runs.

Open is an access level, was introduced to impose limitations on class inheritance on Swift.

This means that the open access level can only be applied to classes and class members.

In Classes

An open class can be subclassed in the module it is defined in and in modules that import the module in which the class is defined.

In Class members

The same applies to class members. An open method can be overridden by subclasses in the module it is defined in and in modules that import the module in which the method is defined.

THE NEED FOR THIS UPDATE

Some classes of libraries and frameworks are not designed to be subclassed and doing so may result in unexpected behavior. Native Apple library also won't allow overriding the same methods and classes,

So after this addition they will apply public and private access levels accordingly.

For more details have look at Apple Documentation on Access Control

Please note this is from 2008. Today I would argue that the serializer should be built in and that you can probably use swagger + attributes to inform consumers about your endpoint and return data.

Iwould argue that you shouldn't be serializing an anonymous type. I know the temptation here; you want to quickly generate some throw-away types that are just going to be used in a loosely type environment aka Javascript in the browser. Still, I would create an actual type and decorate it as Serializable. Then you can strongly type your web methods. While this doesn't matter one iota for Javascript, it does add some self-documentation to the method. Any reasonably experienced programmer will be able to look at the function signature and say, "Oh, this is type Foo! I know how that should look in JSON."

Having said that, you might try JSON.Net to do the serialization. I have no idea if it will work

For me it was due to react-native version in dependency section of package.json file. It was:

"dependencies": {
"expo": "^27.0.1",
"react": "16.3.1",
"react-native": "~0.55.0"
}

I chaged it to:

"dependencies": {
"expo": "^27.0.1",
"react": "16.3.1",
"react-native": "0.52.0"
}

Now it works fine.

you can use Package Manager to add it as package and it is the easiest way to do. You don't need anything else to work with mysql database.

Or you can run below command in Package Manager Console

PM> Install-Package MySql.Data

NUGET Mysql.Data

xDoc.LoadXML("<head><body><Inner> welcome </head> </Inner> <Outer> Bye</Outer>                    
                    </body></head>");

If you want to check you tag name locally, you have to go to the path where you have created tag(local path). Means where you have put your objects. Then type command:

git show --name-only <tagname>

It will show all the objects under that tag name. I am working in Teradata and object means view, table etc

Just call it and supply self

class A:
    def m(self, x, y):
        print(x+y)

class B:
    def call_a(self):
        A.m(self, 1, 2)

b = B()
b.call_a()

output: 3

I would like to advertise the existence of the automatic introspection/reflection toolkit "IDK". It uses a meta-compiler like Qt's and adds meta information directly into object files. It is claimed to be easy to use. No external dependencies. It even allows you to automatically reflect std::string and then use it in scripts. Please look at IDK

Runnable is often used to provide the code that a thread should run, but Runnable itself has nothing to do with threads. It's just an object with a run() method.

In Android, the Handler class can be used to ask the framework to run some code later on the same thread, rather than on a different one. Runnable is used to provide the code that should run later.

$ git diff tag1 tag2

or show log between them:

$ git log tag1..tag2

sometimes it may be convenient to see only the list of files that were changed:

$ git diff tag1 tag2 --stat

and then look at the differences for some particular file:

$ git diff tag1 tag2 -- some/file/name

A tag is only a reference to the latest commit 'on that tag', so that you are doing a diff on the commits between them.

(Make sure to do git pull --tags first)

Also, a good reference: http://learn.github.com/p/diff.html

You should look into Video For Everyone:

Video for Everybody is very simply a chunk of HTML code that embeds a video into a website using the HTML5 element which offers native playback in Firefox 3.5 and Safari 3 & 4 and an increasing number of other browsers.

The video is played by the browser itself. It loads quickly and doesn’t threaten to crash your browser.

In other browsers that do not support , it falls back to QuickTime.

If QuickTime is not installed, Adobe Flash is used. You can host locally or embed any Flash file, such as a YouTube video.

The only downside, is that you have to have 2/3 versions of the same video stored, but you can serve to every existing device/browser that supports video (i.e.: the iPhone).

connection = DriverManager.getConnection("jdbc:sqlite:D:\\testdb.db");

Instead of this put

connection = DriverManager.getConnection("jdbc:sqlite:D:\\testdb");

select @EmpID = ID from dbo.Employee

Or

set @EmpID =(select id from dbo.Employee)

Note that the select query might return more than one value or rows. so you can write a select query that must return one row.

If you would like to add more columns to one variable(MS SQL), there is an option to use table defined variable

DECLARE @sampleTable TABLE(column1 type1)
INSERT INTO @sampleTable
SELECT columnsNumberEqualInsampleTable FROM .. WHERE ..

As table type variable do not exist in Oracle and others, you would have to define it:

DECLARE TYPE type_name IS TABLE OF (column_type | variable%TYPE | table.column%TYPE [NOT NULL] INDEX BY BINARY INTEGER;

-- Then to declare a TABLE variable of this type: variable_name type_name;

-- Assigning values to a TABLE variable: variable_name(n).field_name := 'some text';

-- Where 'n' is the index value

CodePress does this, as does EditArea. Both are open source.

None of the answers worked for me because all my HTML was in a single line.

Basically you need first to break each line with the following command that substitutes >< with the same characters but with a line break in the middle.

:%s/></>\r</g

Then the command

gg=G

will indent the file.

I wouldn't recommend any of these methods. Instead, put it within its own namespace.

class Post < ActiveRecord::Base
  def clean_input
    self.input = Helpers.sanitize(self.input, :tags => %w(b i u))
  end

  module Helpers
    extend ActionView::Helpers::SanitizeHelper
  end
end

hey I understand this is an old thread but I have a query in regards to apachebenchmarking. how do you collect the metrics from apache benchmarking. P.S: I have to do it via telegraf and put it to influxdb . any suggestions/advice/help would be appreciated. Thanks a ton.

I do also have a huge masochistic streak as that I've written yet another JSON parser. This one uses a procedural approach. It uses a similat SQL hierarchy list table to store the parsed data. Also in the package are:

• Reverse process: from hierarchy to JSON
• Querying functions: to fetch particular values from a JSON object

Please feel free to use and have fun with it

Thinking of a string as a set of characters, in mathematics the empty set is always a subset of any set.

There are currently three distinct events which may or may not be triggered when the client devices moves. Two of them are focused around orientation and the last on motion:

• ondeviceorientation is known to work on the desktop version of Chrome, and most Apple laptops seems to have the hardware required for this to work. It also works on Mobile Safari on the iPhone 4 with iOS 4.2. In the event handler function, you can access alpha, beta, gamma values on the event data supplied as the only argument to the function.

• onmozorientation is supported on Firefox 3.6 and newer. Again, this is known to work on most Apple laptops, but might work on Windows or Linux machines with accelerometer as well. In the event handler function, look for x, y, z fields on the event data supplied as first argument.

• ondevicemotion is known to work on iPhone 3GS + 4 and iPad (both with iOS 4.2), and provides data related to the current acceleration of the client device. The event data passed to the handler function has acceleration and accelerationIncludingGravity, which both have three fields for each axis: x, y, z

The "earthquake detecting" sample website uses a series of if statements to figure out which event to attach to (in a somewhat prioritized order) and passes the data received to a common tilt function:

if (window.DeviceOrientationEvent) {
    window.addEventListener("deviceorientation", function () {
        tilt([event.beta, event.gamma]);
    }, true);
} else if (window.DeviceMotionEvent) {
    window.addEventListener('devicemotion', function () {
        tilt([event.acceleration.x * 2, event.acceleration.y * 2]);
    }, true);
} else {
    window.addEventListener("MozOrientation", function () {
        tilt([orientation.x * 50, orientation.y * 50]);
    }, true);
}

The constant factors 2 and 50 are used to "align" the readings from the two latter events with those from the first, but these are by no means precise representations. For this simple "toy" project it works just fine, but if you need to use the data for something slightly more serious, you will have to get familiar with the units of the values provided in the different events and treat them with respect :)

If you're using getApplicationContext() as Context in Activity for the dialog like this

Dialog dialog = new Dialog(getApplicationContext());

then use YourActivityName.this

Dialog dialog = new Dialog(YourActivityName.this);

I have an solution for a generic List<> with dynamic binded items.

class PersonalList it's the root element

[XmlRoot("PersonenListe")]
[XmlInclude(typeof(Person))] // include type class Person
public class PersonalList
{
    [XmlArray("PersonenArray")]
    [XmlArrayItem("PersonObjekt")]
    public List<Person> Persons = new List<Person>();

    [XmlElement("Listname")]
    public string Listname { get; set; }

    // Konstruktoren 
    public PersonalList() { }

    public PersonalList(string name)
    {
        this.Listname = name;
    }

    public void AddPerson(Person person)
    {
        Persons.Add(person);
    }
}

class Person it's an single list element

[XmlType("Person")] // define Type
[XmlInclude(typeof(SpecialPerson)), XmlInclude(typeof(SuperPerson))]  
        // include type class SpecialPerson and class SuperPerson
public class Person
{
    [XmlAttribute("PersID", DataType = "string")]
    public string ID { get; set; }

    [XmlElement("Name")]
    public string Name { get; set; }

    [XmlElement("City")]
    public string City { get; set; }

    [XmlElement("Age")]
    public int Age { get; set; }

    // Konstruktoren 
    public Person() { }

    public Person(string name, string city, int age, string id)
    {
        this.Name = name;
        this.City = city;
        this.Age = age;
        this.ID = id;
    }
}

class SpecialPerson inherits Person

[XmlType("SpecialPerson")] // define Type
public class SpecialPerson : Person
{
    [XmlElement("SpecialInterests")]
    public string Interests { get; set; }

    public SpecialPerson() { }

    public SpecialPerson(string name, string city, int age, string id, string interests)
    {
        this.Name = name;
        this.City = city;
        this.Age = age;
        this.ID = id;
        this.Interests = interests;
    }
}

class SuperPerson inherits Person

[XmlType("SuperPerson")] // define Type
public class SuperPerson : Person
{
    [XmlArray("Skills")]
    [XmlArrayItem("Skill")]
    public List<String> Skills { get; set; }

    [XmlElement("Alias")]
    public string Alias { get; set; }

    public SuperPerson() 
    {
        Skills = new List<String>();
    }

    public SuperPerson(string name, string city, int age, string id, string[] skills, string alias)
    {
        Skills = new List<String>();

        this.Name = name;
        this.City = city;
        this.Age = age;
        this.ID = id;
        foreach (string item in skills)
        {
            this.Skills.Add(item);   
        }
        this.Alias = alias;
    }
}

and the main test Source

static void Main(string[] args)
{
    PersonalList personen = new PersonalList(); 
    personen.Listname = "Friends";

    // normal person
    Person normPerson = new Person();
    normPerson.ID = "0";
    normPerson.Name = "Max Man";
    normPerson.City = "Capitol City";
    normPerson.Age = 33;

    // special person
    SpecialPerson specPerson = new SpecialPerson();
    specPerson.ID = "1";
    specPerson.Name = "Albert Einstein";
    specPerson.City = "Ulm";
    specPerson.Age = 36;
    specPerson.Interests = "Physics";

    // super person
    SuperPerson supPerson = new SuperPerson();
    supPerson.ID = "2";
    supPerson.Name = "Superman";
    supPerson.Alias = "Clark Kent";
    supPerson.City = "Metropolis";
    supPerson.Age = int.MaxValue;
    supPerson.Skills.Add("fly");
    supPerson.Skills.Add("strong");

    // Add Persons
    personen.AddPerson(normPerson);
    personen.AddPerson(specPerson);
    personen.AddPerson(supPerson);

    // Serialize 
    Type[] personTypes = { typeof(Person), typeof(SpecialPerson), typeof(SuperPerson) };
    XmlSerializer serializer = new XmlSerializer(typeof(PersonalList), personTypes); 
    FileStream fs = new FileStream("Personenliste.xml", FileMode.Create); 
    serializer.Serialize(fs, personen); 
    fs.Close(); 
    personen = null;

    // Deserialize 
    fs = new FileStream("Personenliste.xml", FileMode.Open); 
    personen = (PersonalList)serializer.Deserialize(fs); 
    serializer.Serialize(Console.Out, personen);
    Console.ReadLine();
}

Important is the definition and includes of the diffrent types.

if anyone is interested to see the super simple solution written in Kotlin, check the blogpost I just created. The example in the blogpost is based on creating Sectioned RecyclerView:

https://brona.blog/2020/06/sectioned-recyclerview-in-three-steps/

Keep it simple. Use both onKeyPress() and onKeyUp():

<input id="edValue" type="text" onKeyPress="edValueKeyPress()" onKeyUp="edValueKeyPress()">

This takes care of getting the most updated string value (after key up) and also updates if the user holds down a key.

Tested it in FireFox, Chrome and IE. I've also attached an image to show my results of my implementation of this.

EDIT: Also, if you want the image to just toggle back and forth with jQuery, here's the page source for that...I've included the web link to jQuery and and image that's online so you should just be able to copy/paste to test it out:

EDIT 2 (For IE10-11 Users): The solution above will not work with the changes Microsoft has made to the browser as of late, so here's an updated solution that will allow you to grayscale (or desaturate) your images.

<svg>_x000D_
  <defs>_x000D_
    <filter xmlns="http://www.w3.org/2000/svg" id="desaturate">_x000D_
      <feColorMatrix type="saturate" values="0" />_x000D_

  </defs>_x000D_
  <image xlink:href="http://www.polyrootstattoo.com/images/Artists/Buda/40.jpg" width="600" height="600" filter="url(#desaturate)" />_x000D_
</svg>

create table like this,

CommentId    UserId
---------------------
   1            usr1
   1            usr2

In this way you can check whether the user posted the comments are not.. Apart from this there should be tables for Comments and Users with respective id's

Another use for bootstrap.yml is to load configuration from kubernetes configmap and secret resources. The application must import the spring-cloud-starter-kubernetes dependency.

As with the Spring Cloud Config, this has to take place during the bootstrap phrase.

From the docs :

spring:
  application:
    name: cloud-k8s-app
  cloud:
    kubernetes:
      config:
        name: default-name
        namespace: default-namespace
        sources:
         # Spring Cloud Kubernetes looks up a ConfigMap named c1 in namespace default-namespace
         - name: c1

So properties stored in the configmap resource with meta.name default-name can be referenced just the same as properties in application.yml

And the same process applies to secrets :

spring:
  application:
    name: cloud-k8s-app
  cloud:
    kubernetes:
      secrets:
        name: default-name
        namespace: default-namespace
        sources:
         # Spring Cloud Kubernetes looks up a Secret named s1 in namespace default-namespace
         - name: s1

Here's a a couple of useful link that I found when I started with JNI

http://en.wikipedia.org/wiki/Java_Native_Interface
http://download.oracle.com/javase/1.5.0/docs/guide/jni/spec/functions.html

concerning your problem you can use this

JNIEXPORT void JNICALL Java_ClassName_MethodName(JNIEnv *env, jobject obj, jstring javaString)   
{
   const char *nativeString = env->GetStringUTFChars(javaString, 0);

   // use your string

   env->ReleaseStringUTFChars(javaString, nativeString);
}

open the services window as administrator,Then try to start the service.That worked for me.

Also consider devd a small webserver written in go. Binaries for many platforms are available here.

devd -ol path/to/files/to/serve

It's small, fast, and provides some interesting optional features like live-reloading when your files change.

You can do this:

CSS:

#container {
    height:175px;
}

#container h3{
    position:absolute;
    bottom:0;
    left:0;
}

Then in HTML:

<div class="row">
    <div class="col-sm-6">
        <img src="//placehold.it/600x300" alt="Logo" />
    </div>
    <div id="container" class="col-sm-6">
        <h3>Some Text</h3>
    </div>
</div>

During debugging I find it useful to put a table at the bottom of each of my pages to show all ModelState errors.

<table class="model-state">
    @foreach (var item in ViewContext.ViewData.ModelState) 
    {
        if (item.Value.Errors.Any())
        { 
        <tr>
            <td><b>@item.Key</b></td>
            <td>@((item.Value == null || item.Value.Value == null) ? "<null>" : item.Value.Value.RawValue)</td>
            <td>@(string.Join("; ", item.Value.Errors.Select(x => x.ErrorMessage)))</td>
        </tr>
        }
    }
</table>

<style>
    table.model-state
    {
        border-color: #600;
        border-width: 0 0 1px 1px;
        border-style: solid;
        border-collapse: collapse;
        font-size: .8em;
        font-family: arial;
    }

    table.model-state td
    {
        border-color: #600;
        border-width: 1px 1px 0 0;
        border-style: solid;
        margin: 0;
        padding: .25em .75em;
        background-color: #FFC;
    }
 </style>

ExpectedConditions is obsolete, so:

        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(15));
        wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.AlertIsPresent());

Either you initialize the variable to something

char retChar = 'x';

or you leave it automatically initialized, which is

char retChar = '\0';

an ascii 0, the same as

char retChar = (char) 0;

What can one initialize char values to?

Sounds undecided between automatic initialisation, which means, you have no influence, or explicit initialisation. But you cannot change the default.

Add android:includeFontPadding="false" to see if it helps.And make text view size same as that of text size rather than "wrap content".It will definitely work.

Suppose the data is in the B column, write in the C column the formula:

=SUBSTITUTE(B1," ","")

Copy&Paste the formula in the whole C column.

edit: using commas or semicolons as parameters separator depends on your regional settings (I have to use the semicolons). This is weird I think. Thanks to @tocallaghan and @pablete for pointing this out.

I only got two timestamps in millisecond, so I have to do some extra steps with moment.js to get the days between.

const getDaysDiff = (fromTimestamp, toTimestamp) => {
    // set timezone offset with utcOffset if needed
    let fromDate = moment(fromTimestamp).utcOffset(8);
    let toDate = moment(toTimestamp).utcOffset(8);
    // get the start moment of the day
    fromDate.set({'hour':0, 'minute': 0, 'second': 0, 'millisecond': 0});
    toDate.set({'hour':0, 'minute': 0, 'second': 0, 'millisecond': 0});
    let diffDays = toDate.diff(fromDate, 'days');

    return diffDays;
}

getDaysDiff(1528889400000, 1528944180000)// 1 

i do it like this cover button and the middle image that

<button><img src="foldername/imagename" width="30px" height= "30px"></button>

I have seen one person/previous answer use .concat() in an array, but not like this...

I have used concat to add to a string and then just render the JSX content on the element via the jQuery selector:

let list = "<div><ul>";

for (let i=0; i<myArray.length; i++) {
    list = list.concat(`<li>${myArray[i].valueYouWant}</li>`);
}

list = list.concat("</ul></div>);

$("#myItem").html(list);

This is a known issue with Chrome.

If you want to pull out only the index values for certain integer-based row-indices, you can do something like the following using the iloc method:

In [28]: temp
Out[28]:
       index                 time  complete
row_0      2  2014-10-22 01:00:00         0
row_1      3  2014-10-23 14:00:00         0
row_2      4  2014-10-26 08:00:00         0
row_3      5  2014-10-26 10:00:00         0
row_4      6  2014-10-26 11:00:00         0

In [29]: temp.iloc[[0,1,4]].index
Out[29]: Index([u'row_0', u'row_1', u'row_4'], dtype='object')

In [30]: temp.iloc[[0,1,4]].index.tolist()
Out[30]: ['row_0', 'row_1', 'row_4']

It's quite easy to roll back just a specific migration.
Since the command php artisan migrate:rollback, undo the last database migration, and the order of the migrations execution is stored in the batch field in the migrations table.

You can edit the batch value of the migration that you want to rollback and set it as the higher. Then you can rollback that migration with a simple:

php artisan migrate:rollback

After editing the same migration you can execute it again with a simple

php artisan migrate

NOTICE: if two or more migrations have the same higher value, they will be all rolled back at the same time.

"cat".split("(?!^)")

This will produce

array ["c", "a", "t"]

GET is visible to anyone (even the one on your shoulder now) and is saved on cache, so is less secure of using post, btw post without some cryptographics routine is not sure, for a bit of security you've to use SSL (https)

According to pip documentation at

http://pip.readthedocs.org/en/stable/user_guide/#configuration

You will need to specify the default install location within a pip.ini file, which, also according to the website above is usually located as follows

On Unix and Mac OS X the configuration file is: $HOME/.pip/pip.conf

On Windows, the configuration file is: %HOME%\pip\pip.ini

The %HOME% is located in C:\Users\Bob on windows assuming your name is Bob

On linux the $HOME directory can be located by using cd ~

You may have to create the pip.ini file when you find your pip directory. Within your pip.ini or pip.config you will then need to put (assuming your on windows) something like

[global]
target=C:\Users\Bob\Desktop

Except that you would replace C:\Users\Bob\Desktop with whatever path you desire. If you are on Linux you would replace it with something like /usr/local/your/path

After saving the command would then be

pip install pandas

However, the program you install might assume it will be installed in a certain directory and might not work as a result of being installed elsewhere.

Problem fixed :)

below is the working code

$(function(){
    $('#datepicker').datepicker({
        startDate: '-0m'
        //endDate: '+2d'
    }).on('changeDate', function(ev){
        $('#sDate1').text($('#datepicker').data('date'));
        $('#datepicker').datepicker('hide');
    });

})

SOAP

Simple Object Access Protocol (SOAP) is a standard, an XML language, defining a message architecture and message formats. It is used by Web services. It contains a description of the operations.

WSDL is an XML-based language for describing Web services and how to access them. It will run on SMTP, HTTP, FTP, etc. It requires middleware support and well-defined mechanism to define services like WSDL+XSD and WS-Policy. SOAP will return XML based data

REST

Representational State Transfer (RESTful) web services. They are second-generation Web services.

RESTful web services communicate via HTTP rather than SOAP-based services and do not require XML messages or WSDL service-API definitions. For REST middleware is not required, only HTTP support is needed. It is a WADL standard, REST can return XML, plain text, JSON, HTML, etc.

I am not sure if the question is still relevant but after referring to scrollIntoView documentation from https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView.

The easiest solution would be

executor.executeScript("arguments[0].scrollIntoView({block: \"center\",inline: \"center\",behavior: \"smooth\"});",element);

This scrolls the element into center of the page.

open a terminal and enter

node -v

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

node

Prompt must be change. Enter following,

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

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

'Node is working'

<div id="music">
<audio autoplay>
  <source src="kooche.mp3" type="audio/mpeg">
  <p>If you can read this, your browser does not support the audio element.</p>
</audio>
</div>

And the css:

#music {
  display:none;
}

Like suggested above, you probably should have the controls available in some form. Maybe use a toggle link/checkbox that slides the controls in via jquery.

NSMutableArray *array = [[NSMutableArray alloc] initWithObjects:@"First",@"Second", nil];

This is a possible implementation of the required Bash function:

# Print the newest file, if any, matching the given pattern
# Example usage:
#   newest_matching_file 'b2*'
# WARNING: Files whose names begin with a dot will not be checked
function newest_matching_file
{
    # Use ${1-} instead of $1 in case 'nounset' is set
    local -r glob_pattern=${1-}

    if (( $# != 1 )) ; then
        echo 'usage: newest_matching_file GLOB_PATTERN' >&2
        return 1
    fi

    # To avoid printing garbage if no files match the pattern, set
    # 'nullglob' if necessary
    local -i need_to_unset_nullglob=0
    if [[ ":$BASHOPTS:" != *:nullglob:* ]] ; then
        shopt -s nullglob
        need_to_unset_nullglob=1
    fi

    newest_file=
    for file in $glob_pattern ; do
        [[ -z $newest_file || $file -nt $newest_file ]] \
            && newest_file=$file
    done

    # To avoid unexpected behaviour elsewhere, unset nullglob if it was
    # set by this function
    (( need_to_unset_nullglob )) && shopt -u nullglob

    # Use printf instead of echo in case the file name begins with '-'
    [[ -n $newest_file ]] && printf '%s\n' "$newest_file"

    return 0
}

It uses only Bash builtins, and should handle files whose names contain newlines or other unusual characters.

Be careful to use a C compiler, not C++ if you're actually doing C. While most programs in C will work using a C++ compiler there are enough differences that there can be problems. I would agree with the people who suggest using gcc via cygwin.

EDIT:
http://en.wikipedia.org/wiki/Compatibility_of_C_and_C%2B%2B shows some of the major differences

I am reading some data from a file using read. Here I am reading data in a 2d char pointer but the method is the same for the 1d also. Just read character by character and do not worry about the exceptions because the condition in the while loop is handling the exceptions :D

  while ( (n = read(fd, buffer,1)) > 0 )
{   

if(buffer[0] == '\n')
{
  r++;
  char**tempData=(char**)malloc(sizeof(char*)*r);

  for(int a=0;a<r;a++)
  {
    tempData[a]=(char*)malloc(sizeof(char)*BUF_SIZE);
    memset(tempData[a],0,BUF_SIZE);
  }

  for(int a=0;a<r-1;a++)
  {
    strcpy(tempData[a],data[a]);
  }

   data=tempData;

   c=0;
}

else
{
  data[r-1][c]=buffer[0];
  c++;
  buffer[1]='\0';
}

   }

This is difficult to achieve, but the cookie expiration date can be set in another cookie. This cookie can then be read later to get the expiration date. Maybe there is a better way, but this is one of the methods to solve your problem.

In acrhiecture - sometimes to support 6.0 and 7.0 , we exlude arm64

In architectures - > acrchitecture - select standard architecture arm64 armv7 armv7s. Just below in Valid acrchitecture make user arm64 armv7 armv7s is included. This worked for me.

I use comments.vim from Jasmeet Singh Anand (found on vim.org),

It works with C, C++, Java, PHP[2345], proc, CSS, HTML, htm, XML, XHTML, vim, vimrc, SQL, sh, ksh, csh, Perl, tex, fortran, ml, caml, ocaml, vhdl, haskel, and normal files

It comments and un-comments lines in different source files in both normal and visual mode

Usage:

• CtrlC to comment a single line
• CtrlX to un-comment a single line
• ShiftV and select multiple lines, then CtrlC to comment the selected multiple lines
• ShiftV and select multiple lines, then CtrlX to un-comment the selected multiple lines

The official mongo image has merged a PR to include the functionality to databases and admin users at startup.

The database initialisation will run scripts in /docker-entrypoint-initdb.d/ when there is nothing populated in the /data/db directory.

Database Initialisation

The mongo container image provides the /docker-entrypoint-initdb.d/ path to deploy custom .js or .sh setup scripts that will be run once on database initialisation. .js scripts will be run against test by default or MONGO_INITDB_DATABASE if defined in the environment.

COPY mysetup.sh /docker-entrypoint-initdb.d/

or

COPY mysetup.js /docker-entrypoint-initdb.d/

A simple initialisation mongo shell javascript file that demonstrates setting up the container collection with data, logging and how to exit with an error (for result checking).

let error = true

let res = [
  db.container.drop(),
  db.container.createIndex({ myfield: 1 }, { unique: true }),
  db.container.createIndex({ thatfield: 1 }),
  db.container.createIndex({ thatfield: 1 }),
  db.container.insert({ myfield: 'hello', thatfield: 'testing' }),
  db.container.insert({ myfield: 'hello2', thatfield: 'testing' }),
  db.container.insert({ myfield: 'hello3', thatfield: 'testing' }),
  db.container.insert({ myfield: 'hello3', thatfield: 'testing' })
]

printjson(res)

if (error) {
  print('Error, exiting')
  quit(1)
}

Admin User Setup

The environment variables to control "root" user setup are

• MONGO_INITDB_ROOT_USERNAME
• MONGO_INITDB_ROOT_PASSWORD

Example

docker run -d \
  -e MONGO_INITDB_ROOT_USERNAME=admin \
  -e MONGO_INITDB_ROOT_PASSWORD=password \
  mongod

or Dockerfile

FROM docker.io/mongo
ENV MONGO_INITDB_ROOT_USERNAME admin
ENV MONGO_INITDB_ROOT_PASSWORD password

You don't need to use --auth on the command line as the docker entrypoint.sh script adds this in when it detects the environment variables exist.
