maybe you can try this: change jdk version. And I resolved this problem by change jdk from 1.6.0_37 to 1.6.0.45 . BR!

try to delete the file and remove the file reference from file entries under the .svn directory

Pretty old question but the most simple answer isn't yet posted.
Here it is :
1) In [workspace]\.metadata\.plugins\org.eclipse.e4.workbench delete workbench.xmi file.
In most cases it's enough - try to load Eclipse.
Still you have to re-configure your specific perspective settings (if any)

2) Now getting problems with building projects that worked perfectly? As of my experience following steps help:
- uncheck Projects->Build automatically
- switch to Java perspective (if not yet): Window -> Open perspective -> Java
- locate Problems view or open it: Window -> Show view -> Problems
- right-click on problem groups and select Delete. Be sure to delete Lint errors
- clean the workspace: Project -> Clean... with option Clean all projects
- check Projects->Build automatically
- if problems persist for some projects: right-click project, select Properties -> Android and make sure appropriate Project Build Target is chosen

3) It was always sufficient for me. But if you still get problems - try @george post recommendations

On MacOS:

1. Get the latest compiled SVN client binaries from here.
2. Install.
3. Add binaries to path (the last installation screen explains how).
4. Open terminal and run the following command on your project directory:

   svn upgrade

At my day job I sit behind a corporate firewall protecting and caching web traffic (among other things). For the most part it stays out of the way. But sometimes it rears its ugly head and stands firmly in the path of what I am trying to do.

Earlier this week I was trying to look at a cool new general validation system for ColdFusion called Validat, put out by the great guys at Alagad. They don't have a download on the RIAForge site yet, but the files are available via SVN. I loaded up the subclipse plugin into my Eclipse, restarted and began adding the Validat SVN repository. I started getting errors abou the "RA layer request failed" and "svn: PROPFIND request failed on /Validat/trunk", followed by an error about not being able to connect to the SVN server.

I already had Eclipse setup with my proxy settings, so I thought I was doing something wrong or Alagad didn't actually have the subversion repository up-and-available. After going home that night, I tried it from home and wa-la it worked. Stupid proxy server! So the subclipse plugin won't use the Eclipse proxy settings. (Can that be fixed please!). After digging around the subclipse help site and being redirected to the collab.net help, then unproductively searching through the eclipse workspace, plugins, and configuration folders for the settings file, I was finally able to figure out how to set up subclipse to use the proxy server.

In my Windows development environment, I opened the following file: C:\Documents and Settings\MyUserId\Application Data\Subversion\servers in my favorite text editor. Near the bottom of that file is a [global] section with http-proxy-host and http-proxy-port settings. I uncommented those two lines, modified them for my corporate proxy server, went back to the SVN Repository view in Eclipse, refreshed the Validat repository and Boom! it worked!

from http://www.mkville.com/blog/index.cfm/2007/11/8/Using-Subclipse-Behind-a-Proxy-Server

The solution to this question is very easy: Vectors

std::vector<int> vector;
for(int i = 0; i < 10;i++)
{
    vector.push_back(i);
}
std::reverse(vector.begin(), vector.end());

Voila! You are done! =)

Solution details:

This is the most efficent solution: Swap can't swap 3 values but reverse definitely can. Remember to include algorithm. This is so simple that the compiled code is definitely not needed.

I think this solves the OP's problem

If you think there are any errors and problems with this solution please comment below

In my case, I could not get the answer by @Sampson to work for me, at best I got a single column centered on the page. In the process however, I learned how the float actually works and created this solution. At it's core the fix is very simple but hard to find as evident by this thread which has had more than 146k views at the time of this post without mention.

All that is needed is to total the amount of screen space width that the desired layout will occupy then make the parent the same width and apply margin:auto. That's it!

The elements in the layout will dictate the width and height of the "outer" div. Take each "myFloat" or element's width or height + its borders + its margins and its paddings and add them all together. Then add the other elements together in the same fashion. This will give you the parent width. They can all be somewhat different sizes and you can do this with fewer or more elements.

Ex.(each element has 2 sides so border, margin and padding get multiplied x2)

So an element that has a width of 10px, border 2px, margin 6px, padding 3px would look like this: 10 + 4 + 12 + 6 = 32

Then add all of your element's totaled widths together.

Element 1 = 32
Element 2 = 24
Element 3 = 32
Element 4 = 24

In this example the width for the "outer" div would be 112.

This is adapted from CodesInChaos's extension method. The name is shorter (NotNull) and more importantly, restricts the type (T) to reference types with where T : class.

    public static IEnumerable<T> NotNull<T>(this IEnumerable<T> source) where T : class
    {
        return source.Where(item => item != null);
    }

you have a click listner but you haven't initialized the mAddTaskButton with your layout binding

It is good idea to use factory methods inside object when:

1. Object's class doesn't know what exact sub-classes it have to create
2. Object's class is designed so that objects it creates were specified by sub-classes
3. Object's class delegates its duties to auxiliary sub-classes and doesn't know what exact class will take these duties

It is good idea to use abstract factory class when:

1. Your object shouldn't depend on how its inner objects are created and designed
2. Group of linked objects should be used together and you need to serve this constraint
3. Object should be configured by one of several possible families of linked objects that will be a part of your parent object
4. It is required to share child objects showing interfaces only but not an implementation

In VBA we can not use if jj = 5 or 6 then we must use if jj = 5 or jj = 6 then

maybe this:

If inputWks.Range("d9") > 0 And (inputWks.Range("d11") = "Restricted_Expenditure" Or inputWks.Range("d11") = "Unrestricted_Expenditure") Then

These days you can also use the Web API ResizeObserver.

Simple example:

const resizeObserver = new ResizeObserver(() => {
    console.log('size changed');
});

resizeObserver.observe(document.querySelector('#myElement'));

Using vh on mobile devices is not going to work with 100vh, due to their design choices using the entire height of the device not including any address bars etc.

If you are looking for a layout including div heights proportionate to the true view height I use the following pure css solution:

:root {
  --devHeight: 86vh; //*This value changes
}

.div{
    height: calc(var(--devHeight)*0.10); //change multiplier to suit required height
}

You have two options for setting the viewport height, manually set the --devHeight to a height that works (but you will need to enter this value for each type of device you are coding for)

or

Use javascript to get the window height and then update --devheight on loading and refreshing the viewport (however this does require using javascript and is not a pure css solution)

Once you obtain your correct view height you can create multiple divs at an exact percentage of total viewport height by simply changing the multiplier in each div you assign the height to.

0.10 = 10% of view height 0.57 = 57% of view height

Hope this might help someone ;)

The underlying problem revolves around accessing the data within the array, as Felix Kling points out in the first response.

In the following code, I've accessed the values of the array with the print and echo constructs.

function data()
{

    $a = "abc";
    $b = "def";
    $c = "ghi";

    $array = array($a, $b, $c);

    print_r($array);//outputs the key/value pair

    echo "<br>";

    echo $array[0].$array[1].$array[2];//outputs a concatenation of the values

}

data();

normally, Maxim Donnie's method can find the reason. But I encountered one 400 bad request will not log to err_log. I found the reason with the help with tcpdump

Looking under the hood, the two statements will be transformed into different query representations. Depending on the QueryProvider of Collection, this might be optimized away or not.

When this is a linq-to-object call, multiple where clauses will lead to a chain of IEnumerables that read from each other. Using the single-clause form will help performance here.

When the underlying provider translates it into a SQL statement, the chances are good that both variants will create the same statement.

CSS can not be used to animation, or any style modification on events.

The only way is to use a javascript function, which will return the width of a given element, then, subtract 100px to it, and set the new width size.

Assuming you are using jQuery, you could do something like that:

oldWidth = $('#yourElem').width();
$('#yourElem').width(oldWidth-100);

And with native javascript:

oldWidth = document.getElementById('yourElem').clientWidth;
document.getElementById('yourElem').style.width = oldWidth-100+'px';

We assume that you have a css style set with 100%;

Because you say

struct arg_struct *args = (struct arg_struct *)args;

instead of

struct arg_struct *args = arguments;

If you simply want to see the column names this one line should provide it without changing any settings:

describe database.tablename;

However, if that doesn't work for your version of hive this code will provide it, but your default database will now be the database you are using:

use database;
describe tablename;

distinct is not a function. It always operates on all columns of the select list.

Your problem is a typical "greatest N per group" problem which can easily be solved using a window function:

select ...
from (
  select IDNo,
         FirstName,
         LastName,
         ....,
         row_number() over (partition by lower(idno) order by firstname) as rn 
  from people 
) t
where rn = 1;

Using the order by clause you can select which of the duplicates you want to pick.

The above can be used in a left join, see below:

select ...
from x
  left join (
    select IDNo,
           FirstName,
           LastName,
           ....,
           row_number() over (partition by lower(idno) order by firstname) as rn 
    from people 
  ) p on p.idno = x.idno and p.rn = 1
where ...

np.where function works as follows:

df['X'] = np.where(df['Y']>=50, 'yes', 'no')

In your case you would want:

import numpy as np
df['my_channel'] = np.where(df.my_channel > 20000, 0, df.my_channel)

If you are working in Eclipse IDE, that could mean that you haven't close the file in the previous launch of the application. When I had the same error message at trying to delete a file, that was the reason. It seems, Eclipse IDE doesn't close all files after termination of an application.

Lots of work toward uniform versioning and in support of conventions has been completed since this question was first asked. Palatable options are now detailed in the Python Packaging User Guide. Also noteworthy is that version number schemes are relatively strict in Python per PEP 440, and so keeping things sane is critical if your package will be released to the Cheese Shop.

Here's a shortened breakdown of versioning options:

1. Read the file in setup.py (setuptools) and get the version.
2. Use an external build tool (to update both __init__.py as well as source control), e.g. bump2version, changes or zest.releaser.
3. Set the value to a __version__ global variable in a specific module.
4. Place the value in a simple VERSION text file for both setup.py and code to read.
5. Set the value via a setup.py release, and use importlib.metadata to pick it up at runtime. (Warning, there are pre-3.8 and post-3.8 versions.)
6. Set the value to __version__ in sample/__init__.py and import sample in setup.py.
7. Use setuptools_scm to extract versioning from source control so that it's the canonical reference, not code.

NOTE that (7) might be the most modern approach (build metadata is independent of code, published by automation). Also NOTE that if setup is used for package release that a simple python3 setup.py --version will report the version directly.

use window.localStorage... like this

var refresh = $window.localStorage.getItem('refresh');

Removing an object from a json

It worker for me.

  arrList = $.grep(arrList, function (e) { 

        if(e.worker_id == worker_id) {
            return false;
        } else {
            return true;
        }
    });

It returns an array without that object.

Hope it helps.

server.session.timeout in the application.properties file is now deprecated. The correct setting is:

server.servlet.session.timeout=60s

Also note that Tomcat will not allow you to set the timeout any less than 60 seconds. For details about that minimum setting see https://github.com/spring-projects/spring-boot/issues/7383.

You can use Low Profile mode See here

Just search for SYSTEM_UI_FLAG_LOW_PROFILE that also dims the navigation buttons if they are present of screen.

The best and the most effective way to learn new things is to see and study real world practical examples. Suppose for a moment that you want to build a blog in django where reporters can write and publish news articles. The owner of the online newspaper wants to allow each of his reporters to publish as many articles as they want, but does not want different reporters to work on the same article. This means that when readers go and read an article they will se only one author in the article.

For example: Article by John, Article by Harry, Article by Rick. You can not have Article by Harry & Rick because the boss does not want two or more authors to work on the same article.

How can we solve this 'problem' with the help of django? The key to the solution of this problem is the django ForeignKey.

The following is the full code which can be used to implement the idea of our boss.

from django.db import models

# Create your models here.

class Reporter(models.Model):
    first_name = models.CharField(max_length=30)

    def __unicode__(self):
        return self.first_name


class Article(models.Model):
    title = models.CharField(max_length=100)
    reporter = models.ForeignKey(Reporter)

    def __unicode__(self):
        return self.title

Run python manage.py syncdb to execute the sql code and build the tables for your app in your database. Then use python manage.py shell to open a python shell.

Create the Reporter object R1.

In [49]: from thepub.models import Reporter, Article

In [50]: R1 = Reporter(first_name='Rick')

In [51]: R1.save()

Create the Article object A1.

In [5]: A1 = Article.objects.create(title='TDD In Django', reporter=R1)

In [6]: A1.save()

Then use the following piece of code to get the name of the reporter.

In [8]: A1.reporter.first_name
Out[8]: 'Rick'

Now create the Reporter object R2 by running the following python code.

In [9]: R2 = Reporter.objects.create(first_name='Harry')

In [10]: R2.save()

Now try to add R2 to the Article object A1.

In [13]: A1.reporter.add(R2)

It does not work and you will get an AttributeError saying 'Reporter' object has no attribute 'add'.

As you can see an Article object can not be related to more than one Reporter object.

What about R1? Can we attach more than one Article objects to it?

In [14]: A2 = Article.objects.create(title='Python News', reporter=R1)

In [15]: R1.article_set.all()
Out[15]: [<Article: Python News>, <Article: TDD In Django>]

This practical example shows us that django ForeignKey is used to define many-to-one relationships.

OneToOneField is used to create one-to-one relationships.

We can use reporter = models.OneToOneField(Reporter) in the above models.py file but it is not going to be useful in our example as an author will not be able to post more than one article.

Each time you want to post a new article you will have to create a new Reporter object. This is time consuming, isn't it?

I highly recommend to try the example with the OneToOneField and realize the difference. I am pretty sure that after this example you will completly know the difference between django OneToOneField and django ForeignKey.

You could also try setting style inline without using a variable, like so:

style={{"height" : "100%"}} or,

for multiple attributes: style={{"height" : "100%", "width" : "50%"}}

Just delete the user related data from mysql.db(maybe from other tables too), then recreate both.

INSERT INTO DestinationTable(SupplierName, Country)
SELECT SupplierName, Country FROM SourceTable;

It is not mandatory column names to be same.

Use read with a heredoc as shown below:

read -d '' sql << EOF
select c1, c2 from foo
where c1='something'
EOF

echo "$sql"

The simplest way to get an input box is with the Read-Host cmdlet and -AsSecureString parameter.

$us = Read-Host 'Enter Your User Name:' -AsSecureString
$pw = Read-Host 'Enter Your Password:' -AsSecureString

This is especially useful if you are gathering login info like my example above. If you prefer to keep the variables obfuscated as SecureString objects you can convert the variables on the fly like this:

[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))
[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pw))

If the info does not need to be secure at all you can convert it to plain text:

$user = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))

Read-Host and -AsSecureString appear to have been included in all PowerShell versions (1-6) but I do not have PowerShell 1 or 2 to ensure the commands work identically. https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/read-host?view=powershell-3.0

By default Ansible will attempt to run on all hosts in parallel. See these Ansible docs for details. You can also use the serial parameter to limit the number of parallel hosts you want to be processed at any given time, so if you want to have a playbook run on just one host at a time you can specify serial:1, etc.

Ansible is designed so that each task will be run on all hosts before continuing on to the next task. So if you have 3 tasks it will ensure task 1 runs on all your hosts first, then task 2 is run, then task 3 is run. See this section of the Ansible docs for more details on this.

I would say that if you know a bit of spanish to look at this page, where is properly explained.

However, a fast definition would be that div is for dividing sections and span is for applying some kind of style to an element within another block element like div.

I solved this problem in a completely different way.

Package installer = Conda (Miniconda)
List of available envs = base, djenv(Django environment created for keeping project related modules).

When I was using the command line to activate the djenv using conda activate djenv, the base environment was already activated. I did not notice that and when djenv was activated, (djenv) was being displayed at the beginning of the prompt on the command line. When i tired executing , python manage.py migrate, this happened.
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?

I deactivated the current environment, i.e conda deactivate. This deactivated djenv. Then, i deactivated the base environment.
After that, I again activated djenv. And the command worked like a charm!!

If someone is facing a similar issue, I hope you should consider trying this as well. Maybe it helps.

None of the answers here quite hit the nail on the head.

How to store a datetime in MySQL with timezone info

Use two columns: DATETIME, and a VARCHAR to hold the time zone information, which may be in several forms:

A timezone or location such as America/New_York is the highest data fidelity.

A timezone abbreviation such as PST is the next highest fidelity.

A time offset such as -2:00 is the smallest amount of data in this regard.

Some key points:

• Avoid TIMESTAMP because it's limited to the year 2038, and MySQL relates it to the server timezone, which is probably undesired.
• A time offset should not be stored naively in an INT field, because there are half-hour and quarter-hour offsets.

If it's important for your use case to have MySQL compare or sort these dates chronologically, DATETIME has a problem:

'2009-11-10 11:00:00 -0500' is before '2009-11-10 10:00:00 -0700' in terms of "instant in time", but they would sort the other way when inserted into a DATETIME.

You can do your own conversion to UTC. In the above example, you would then have
'2009-11-10 16:00:00' and '2009-11-10 17:00:00' respectively, which would sort correctly. When retrieving the data, you would then use the timezone info to revert it to its original form.

One recommendation which I quite like is to have three columns:

• local_time DATETIME
• utc_time DATETIME
• time_zone VARCHAR(X) where X is appropriate for what kind of data you're storing there. (I would choose 64 characters for timezone/location.)

An advantage to the 3-column approach is that it's explicit: with a single DATETIME column, you can't tell at a glance if it's been converted to UTC before insertion.

Regarding the descent of accuracy through timezone/abbreviation/offset:

• If you have the user's timezone/location such as America/Juneau, you can know accurately what the wall clock time is for them at any point in the past or future (barring changes to the way Daylight Savings is handled in that location). The start/end points of DST, and whether it's used at all, are dependent upon location, so this is the only reliable way.
• If you have a timezone abbreviation such as MST, (Mountain Standard Time) or a plain offset such as -0700, you will be unable to predict a wall clock time in the past or future. For example, in the United States, Colorado and Arizona both use MST, but Arizona doesn't observe DST. So if the user uploads his cat photo at 14:00 -0700 during the winter months, was he in Arizona or California? If you added six months exactly to that date, would it be 14:00 or 13:00 for the user?

These things are important to consider when your application has time, dates, or scheduling as core function.

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

To use display:none is a good option just to removing an element BUT it will be also removed for screenreaders. There are also discussions if it effects SEO. There's a good, short article on that topic on A List Apart

If you really just want hide and not remove an element, better use:

div {
  position: absolute; 
  left: -999em;
}

Like this it can be also read by screen readers.

The only disadvantage of this method is, that this DIV is actually rendered and it might effect the performance, especially on mobile phones.

You can try to use the runner in atom Hit Ctrl+R (Alt+R on Win/Linux) to launch the runner for the active window. Hit Ctrl+Shift+R (Alt+Shift+R on Win/Linux) to run the currently selected text in the active window. Hit Ctrl+Shift+C to kill a currently running process. Hit Escape to close the runner window

You might implement your class model by composition, having the book object have a map of chapter objects contained within it (map chapter number to chapter object). Your search function could be given a list of books into which to search by asking each book to search its chapters. The book object would then iterate over each chapter, invoking the chapter.search() function to look for the desired key and return some kind of index into the chapter. The book's search() would then return some data type which could combine a reference to the book and some way to reference the data that it found for the search. The reference to the book could be used to get the name of the book object that is associated with the collection of chapter search hits.

Declare an instance of the CBetfairAPI class or make it static.

In my experience, it's not quite that simple. The built-in PHP SOAP client didn't work with the .NET-based SOAP server we had to use. It complained about an invalid schema definition. Even though .NET client worked with that server just fine. By the way, let me claim that SOAP interoperability is a myth.

The next step was NuSOAP. This worked for quite a while. By the way, for God's sake, don't forget to cache WSDL! But even with WSDL cached users complained the damn thing is slow.

Then, we decided to go bare HTTP, assembling the requests and reading the responses with SimpleXMLElemnt, like this:

$request_info = array();

$full_response = @http_post_data(
    'http://example.com/OTA_WS.asmx',
    $REQUEST_BODY,
    array(
        'headers' => array(
            'Content-Type' => 'text/xml; charset=UTF-8',
            'SOAPAction'   => 'HotelAvail',
        ),
        'timeout' => 60,

    ),
    $request_info
);

$response_xml = new SimpleXMLElement(strstr($full_response, '<?xml'));

foreach ($response_xml->xpath('//@HotelName') as $HotelName) {
    echo strval($HotelName) . "\n";
}

Note that in PHP 5.2 you'll need pecl_http, as far as (surprise-surpise!) there's no HTTP client built in.

Going to bare HTTP gained us over 30% in SOAP request times. And from then on we redirect all the performance complains to the server guys.

In the end, I'd recommend this latter approach, and not because of the performance. I think that, in general, in a dynamic language like PHP there's no benefit from all that WSDL/type-control. You don't need a fancy library to read and write XML, with all that stubs generation and dynamic proxies. Your language is already dynamic, and SimpleXMLElement works just fine, and is so easy to use. Also, you'll have less code, which is always good.

mbaird's answer works fine. Just be aware that there seems to be a bug in Android (2.1 at least), that if you set any individual corner's radius to 0, it forces all the corners to 0 (at least that's the case with "dp" units; I didn't try it with any other units).

I needed a shape where the top corners were rounded and the bottom corners were square. I got achieved this by setting the corners I wanted to be square to a value slightly larger than 0: 0.1dp. This still renders as square corners, but it doesn't force the other corners to be 0 radius.

While you are looping in an array with each and if you want to access another array in the context of the current item you do it like this.

Here is the example data.

[
  {
    name: 'foo',
    attr: [ 'boo', 'zoo' ]
  },
  {
    name: 'bar',
    attr: [ 'far', 'zar' ]
  }
]

Here is the handlebars to get the first item in attr array.

{{#each player}}
  <p> {{this.name}} </p>

  {{#with this.attr}}
    <p> {{this.[0]}} </p>
  {{/with}}

{{/each}}

This will output

<p> foo </p>
<p> boo </p>

<p> bar </p>
<p> far </p>

We use the logging module for this.

For example:

import logging
class SomeTest( unittest.TestCase ):
    def testSomething( self ):
        log= logging.getLogger( "SomeTest.testSomething" )
        log.debug( "this= %r", self.this )
        log.debug( "that= %r", self.that )
        # etc.
        self.assertEquals( 3.14, pi )

if __name__ == "__main__":
    logging.basicConfig( stream=sys.stderr )
    logging.getLogger( "SomeTest.testSomething" ).setLevel( logging.DEBUG )
    unittest.main()

That allows us to turn on debugging for specific tests which we know are failing and for which we want additional debugging information.

My preferred method, however, isn't to spend a lot of time on debugging, but spend it writing more fine-grained tests to expose the problem.

As mentioned by MatBailie This is much more safe since it is not a dynamic query and ther are lesser chances of sql injection . I Added one situation where you even want the where clause to be dynamic . XX YY are Columns names

            CREATE PROCEDURE [dbo].[DASH_getTP_under_TP]
    (
    @fromColumnName varchar(10) ,
    @toColumnName varchar(10) , 
    @ID varchar(10)
    )
    as
    begin

    -- this is the column required for where clause 
    declare @colname varchar(50)
    set @colname=case @fromUserType
        when 'XX' then 'XX'
        when 'YY' then 'YY'
        end
        select SelectedColumnId  from (
       select 
            case @toColumnName 
            when 'XX' then tablename.XX
            when 'YY' then tablename.YY
            end as SelectedColumnId,
        From tablename
        where 
        (case @fromUserType 
            when 'XX' then XX
            when 'YY' then YY
        end)= ISNULL(@ID , @colname) 
    ) as tbl1 group by SelectedColumnId 

    end

Add a column to the query which can sub identify the data to sort on that.

In the below example I use a Common Table Expression with the selects you showed which places them in specific groups in the CTE, and then do a union off of both of those groups into AllStudents.

The final select will then sort AllStudents by the SortIndex column first and then by the name such as:

WITH Juveniles as
(
      Select 1 as [SortIndex], id,name,age From Student
      Where age < 15
),

AStudents as
(
      Select 2 as [SortIndex], id,name,age From Student
      Where Name like "%a%" 
),

AllStudents as
(
      select * from Juveniles
      union 
      select * from AStudents
)

select * from AllStudents
sort by [SortIndex], name;

To summarize, it will get all the students which will be sorted by group first, and subsorted by the name within the group after that.

From the docs:

_trackTrans() Sends both the transaction and item data to the Google Analytics server. This method should be called after _trackPageview(), and used in conjunction with the _addItem() and addTrans() methods. It should be called after items and transaction elements have been set up.

So, according to the docs, the items get sent when you call trackTrans(). Until you do, you can add items, but the transaction will not be sent.

Edit: Further reading led me here:

http://www.analyticsmarket.com/blog/edit-ecommerce-data

Where it clearly says you can start another transaction with an existing ID. When you commit it, the new items you listed will be added to that transaction.

I had this issue occurring in Xcode 10.3 after I switched over to my XCTest unit test target then back to the project run time target.

Turns out I had a different Teams selected in my provisioning profile for each target.

To fix it :

• Clean Build Folder

• Make sure all may targets are using the same Team. See Profile Signing under the general tab.

• If not using same Team for all targets, clean before switching to a build target with

  different team selected.

use source before file name,,

like my file which i want to run from terminal is ./jay/bin/activate

so i used command "source ./jay/bin/activate"

Get PHP SDK from github and run the following code:

<?php
$attachment = array(
    'message' => 'this is my message',
    'name' => 'This is my demo Facebook application!',
    'caption' => "Caption of the Post",
    'link' => 'http://mylink.com',
    'description' => 'this is a description',
    'picture' => 'http://mysite.com/pic.gif',
    'actions' => array(
        array(
            'name' => 'Get Search',
            'link' => 'http://www.google.com'
        )
    )
);

$result = $facebook->api('/me/feed/', 'post', $attachment);

the above code will Post the message on to your wall... and if you want to post onto your friends or others wall then replace me with the Facebook User Id of that user..for further information look out the API Documentation.

You can use:

Select
     count(created_date) as counted_leads,
     created_date as count_date
from
     table
group by
     created_date

Note: It seems this is not the preferred solution because of how the extra line was being added on a Windows system. As stated in the python document:

If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference.

Windows is one such platform where that makes a difference. While changing the line terminator as I described below may have fixed the problem, the problem could be avoided altogether by opening the file in binary mode. One might say this solution is more "elegent". "Fiddling" with the line terminator would have likely resulted in unportable code between systems in this case, where opening a file in binary mode on a unix system results in no effect. ie. it results in cross system compatible code.

From Python Docs:

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.

Original:

As part of optional paramaters for the csv.writer if you are getting extra blank lines you may have to change the lineterminator (info here). Example below adapated from the python page csv docs. Change it from '\n' to whatever it should be. As this is just a stab in the dark at the problem this may or may not work, but it's my best guess.

>>> import csv
>>> spamWriter = csv.writer(open('eggs.csv', 'w'), lineterminator='\n')
>>> spamWriter.writerow(['Spam'] * 5 + ['Baked Beans'])
>>> spamWriter.writerow(['Spam', 'Lovely Spam', 'Wonderful Spam'])

At least in PostgreSQL you can use the column number in the resultset in your GROUP BY clause:

SELECT 
 itemName as ItemName,
 substring(itemName, 1,1) as FirstLetter,
 Count(itemName)
FROM table1
GROUP BY 1, 2

Of course this starts to be a pain if you are doing this interactively and you edit the query to change the number or order of columns in the result. But still.

Very easy:

var stringArr = dataTable.Rows[0].ItemArray.Select(x => x.ToString()).ToArray();

Where DataRow.ItemArray property is an array of objects containing the values of the row for each columns of the data table.

Your problem is rather clear. Perhaps you're looking for extend, to add all elements of another list to an existing list:

>>> x = [1,2]
>>> x.extend([3,4,5])
>>> x
[1, 2, 3, 4, 5]

If you want to convert integers to strings, use str() or string interpolation, possibly combined with a list comprehension, i.e.

>>> x = ['1', '2']
>>> x.extend([str(i) for i in range(3, 6)])
>>> x
['1', '2', '3', '4', '5']

All of this is considered pythonic (ok, a generator expression is even more pythonic but let's stay simple and on topic)

YES YOU CAN do it!! It's a little tricky way ; ) (it almost works on ios)

var iframe = document.createElement("IFRAME");
iframe.setAttribute("src", 'data:text/plain,');
document.documentElement.appendChild(iframe);
if(window.frames[0].window.confirm("Are you sure?")){
    // what to do if answer "YES"
}else{
    // what to do if answer "NO"
}

Enjoy it!

Simple but works well for me

FileName = ActiveWorkbook.Name 
If InStr(FileName, ".") > 0 Then 
   FileName = Left(FileName, InStr(FileName, ".") - 1) 
End If

You should wrap your recursive function call into a

• setTimeout,
• setImmediate or
• process.nextTick

function to give node.js the chance to clear the stack. If you don't do that and there are many loops without any real async function call or if you do not wait for the callback, your RangeError: Maximum call stack size exceeded will be inevitable.

There are many articles concerning "Potential Async Loop". Here is one.

Now some more example code:

// ANTI-PATTERN
// THIS WILL CRASH

var condition = false, // potential means "maybe never"
    max = 1000000;

function potAsyncLoop( i, resume ) {
    if( i < max ) {
        if( condition ) { 
            someAsyncFunc( function( err, result ) { 
                potAsyncLoop( i+1, callback );
            });
        } else {
            // this will crash after some rounds with
            // "stack exceed", because control is never given back
            // to the browser 
            // -> no GC and browser "dead" ... "VERY BAD"
            potAsyncLoop( i+1, resume ); 
        }
    } else {
        resume();
    }
}
potAsyncLoop( 0, function() {
    // code after the loop
    ...
});

This is right:

var condition = false, // potential means "maybe never"
    max = 1000000;

function potAsyncLoop( i, resume ) {
    if( i < max ) {
        if( condition ) { 
            someAsyncFunc( function( err, result ) { 
                potAsyncLoop( i+1, callback );
            });
        } else {
            // Now the browser gets the chance to clear the stack
            // after every round by getting the control back.
            // Afterwards the loop continues
            setTimeout( function() {
                potAsyncLoop( i+1, resume ); 
            }, 0 );
        }
    } else {
        resume();
    }
}
potAsyncLoop( 0, function() {
    // code after the loop
    ...
});

Now your loop may become too slow, because we loose a little time (one browser roundtrip) per round. But you do not have to call setTimeout in every round. Normally it is o.k. to do it every 1000th time. But this may differ depending on your stack size:

var condition = false, // potential means "maybe never"
    max = 1000000;

function potAsyncLoop( i, resume ) {
    if( i < max ) {
        if( condition ) { 
            someAsyncFunc( function( err, result ) { 
                potAsyncLoop( i+1, callback );
            });
        } else {
            if( i % 1000 === 0 ) {
                setTimeout( function() {
                    potAsyncLoop( i+1, resume ); 
                }, 0 );
            } else {
                potAsyncLoop( i+1, resume ); 
            }
        }
    } else {
        resume();
    }
}
potAsyncLoop( 0, function() {
    // code after the loop
    ...
});

If you want customer's details that customer had entered while ordering, then you can use the following code:

$order = new WC_Order($order_id);
$billing_address = $order->get_billing_address();
$billing_address_html = $order->get_formatted_billing_address();

// For printing or displaying on the web page
$shipping_address = $order->get_shipping_address();
$shipping_address_html = $order->get_formatted_shipping_address(); // For printing or displaying on web page

Apart from this, $customer = new WC_Customer( $order_id ); can not get you customer details.

First of all, new WC_Customer() doesn't take any arguments.

Secondly, WC_Customer will get customer's details only when the user is logged in and he/she is not on the admin side. Instead he/she should be on website's front-end like the 'My Account', 'Shop', 'Cart', or 'Checkout' page.

You have to use implicitly unwrapped optionals so that Swift can cope with circular dependencies (parent <-> child of the UI components in this case) during the initialization phase.

@IBOutlet var imgBook: UIImageView!
@IBOutlet var titleBook: UILabel!
@IBOutlet var pageBook: UILabel!

Read this doc, they explain it all nicely.

Unfortunately strictly none of the above solutions worked for me in 2016 (a couple years after the question)

So here's the aggressive solution I use:

function remake(e){
    var val = e.value;
    var id = e.id;
    e.outerHTML = e.outerHTML;
    document.getElementById(id).value = val;
    return true;
}

<input id=MustHaveAnId type=text name=email autocomplete=on onblur="remake(this)">

Basically, it deletes the tag while saving the value, and recreates it, then puts back the value.

you can use :

Process.GetCurrentProcess().MainWindowHandle

As ivan.sim writes in his answer

1. Ensure that your user account has administrator privilege.
2. Disable UAC(User Account Control) as it restricts certain administrative function needed to run a web server.
3. Install in C://xampp.

Problem with the correct answer is in the explanation of point 2., and magicandre1981 writes more about it

Moving the slider down doesn't completely disable UAC since Windows 8. This is changed compared to Windows 7, because the new Store apps require an active UAC. With UAC off, they no longer run.

How can we then disable UAC and install XAMPP?

Easy. Go to Registry Editor and navigate to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

Right click EnableLUA and modify the Value data to 0.

Then restart your computer and you're ready to install XAMPP.

You can use .change for what you want

$("input[@name='lom']").change(function(){
    // Do something interesting here
});

as of jQuery 1.3

you no longer need the '@'. Correct way to select is:

$("input[name='lom']")

The os.makedirs function does this. Try the following:

import os
import errno

filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
    try:
        os.makedirs(os.path.dirname(filename))
    except OSError as exc: # Guard against race condition
        if exc.errno != errno.EEXIST:
            raise

with open(filename, "w") as f:
    f.write("FOOBAR")

The reason to add the try-except block is to handle the case when the directory was created between the os.path.exists and the os.makedirs calls, so that to protect us from race conditions.

In Python 3.2+, there is a more elegant way that avoids the race condition above:

import os

filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
    f.write("FOOBAR")

For a pure Ruby solution combine URI.parse with CGI.parse (this can be used even if Rails/Rack etc. are not required):

CGI.parse(URI.parse(url).query) 
# =>  {"name1" => ["value1"], "name2" => ["value1", "value2", ...] }

awk

awk '{gsub(/two.*/,"")}1' file

Ruby

ruby -ne 'print $_.gsub(/two.*/,"")' file

In lines with the answer of NoToast, you would need to have multiple versions of "your_image" in your res/drawable-ldpi,mdpi, hdpi, x-hdpi (for xtra large screens), remove match_parent and keep android: adjustViewBounds="true"

I did the following:

void BrowserDocumentCompleted(object sender,
        WebBrowserDocumentCompletedEventArgs e)
{
  if (e.Url.AbsolutePath != (sender as WebBrowser).Url.AbsolutePath)
    return; 

  //The page is finished loading 
}

The last page loaded tends to be the one navigated to, so this should work.

From here.

Both SHA256 and MDA5 are hashing algorithms. They take your input data, in this case your file, and output a 256/128-bit number. This number is a checksum. There is no encryption taking place because an infinite number of inputs can result in the same hash value, although in reality collisions are rare.

SHA256 takes somewhat more time to calculate than MD5, according to this answer.

Offhand, I'd say that MD5 would be probably be suitable for what you need.

Here's a function to pretty up your json: pretty_json

I preferred using != instead of <> because sometimes I use the <s></s> syntax to write SQL commands. Using != is more handy to avoid syntax errors in this case.

One line solution:

   [ -f ./myfile ] && echo exists

One line solution with error action:

   [ -f ./myfile ] && echo exists || echo not exists

Example used in my make clean directives:

clean:
    @[ -f ./myfile ] && rm myfile || true

And make clean works without error messages!

SELECT COLUMN_NAME, TABLE_NAME,table_schema

.Net Core has this method built-in: Replace(String, String, StringComparison) Doc. Now we can simply write: "...".Replace("oldValue", "newValue", StringComparison.OrdinalIgnoreCase)

Microsoft Example Rnd Function

I have moved into the world of namespace specific open graph data and therefore dont rely on the FB types. See "edit open graph" in the apps dev tool dashboard.

try the following query:

SELECT ID,
   Name
INTO #tempTable
FROM Table

SELECT *
FROM #tempTable
WHERE ID = 1

It doesn't need to declare table.

These are source maps. Provide these alongside compressed source files; developer tools such as those in Firefox and Chrome will use them to allow debugging as if the code was not compressed.

See Introduction to the POM

finalName is created as:

<build>
    <finalName>${project.artifactId}-${project.version}</finalName>
</build>

One of the solutions is to add own property:

<properties>
    <finalName>${project.artifactId}-${project.version}</finalName>
</properties>
<build>
    <finalName>${finalName}</finalName>
 </build>

And now try:

mvn -DfinalName=build clean package

You can try my suggestion for a work around in Doug's approach.
But if you want to stick with your logic though, you can try this:

Option Explicit

Sub GetUnique()

Dim rng As Range
Dim myarray, myunique
Dim i As Integer

ReDim myunique(1)

With ThisWorkbook.Sheets("Sheet1")
    Set rng = .Range(.Range("A1"), .Range("A" & .Rows.Count).End(xlUp))
    myarray = Application.Transpose(rng)
    For i = LBound(myarray) To UBound(myarray)
        If IsError(Application.Match(myarray(i), myunique, 0)) Then
            myunique(UBound(myunique)) = myarray(i)
            ReDim Preserve myunique(UBound(myunique) + 1)
        End If
    Next
End With

For i = LBound(myunique) To UBound(myunique)
    Debug.Print myunique(i)
Next

End Sub

This uses array instead of range.
It also uses Match function instead of a nested For Loop.
I didn't have the time to check the time difference though.
So I leave the testing to you.

There is a command line tool with a visual aspect - jvm-mon. It is a JVM monitoring tool for the command line that disaplys:

• heap usage, size and max
• jvm processes
• cpu and GC usage
• top threads

The metrics and charts update while the tool is open.

Sample:

Use the sizing utility classes...

• h-50 = height 50%
• h-100 = height 100%

I use the single line

(cd ${FILENAME%/*}; pwd)

However, this can only be used when $FILENAME has a leading path of any kind (relative or absolute) that actually exists. If there is no leading path at all, then the answer is simply $PWD. If the leading path does not exist, then the answer may be indeterminate, otherwise and the answer is simply ${FILENAME%/*} if the path is absolute.

Putting this all together I would suggest using the following function

function abspath() {
  # argument 1: file pathname (relative or absolute)
  # returns: file pathname (absolute)
  if [ "$1" == "${1##*/}" ]; then # no path at all
    echo "$PWD"
  elif [ "${1:0:1}" == "/" -a "${1/../}" == "$1" ]; then # strictly absolute path
    echo "${1%/*}"
  else # relative path (may fail if a needed folder is non-existent)
    echo "$(cd ${1%/*}; pwd)"
  fi
}

Note also that this only work in bash and compatible shells. I don't believe the substitutions work in the simple shell sh.

The box model is something every web-developer should know about. working with percents for sizes and pixels for padding/margin just doesn't work. There always is a resolution at which it doesn't look good (e.g. giving a width of 90% and a padding/margin of 10px in a div with a width of under 100px).

Check this out (using micro.pravi's code): http://jsbin.com/umeduh/2

<div id="container">
    <div class="left">
        <div class="content">
            left
        </div>
    </div>
    <div class="right">
        <div class="content">
            right
            <textarea>Check me out!</textarea>
        </div>
    </div>
</div>

The <div class="content"> are there so you can use padding and margin without screwing up the floats.

this is the most important part of the CSS:

textarea {
    display: block;
    width: 100%;
    -webkit-box-sizing: border-box;
       -moz-box-sizing: border-box;

When a Javascript object property's name doesn't begin with either an underscore or a letter, you cant use the dot notation (like Game.status[0].0), and you must use the alternative notation, which is Game.status[0][0].

One different note, do you really need it to be an object inside the status array? If you're using the object like an array, why not use a real array instead?

Is this what you are trying? I have commented the code so that you will not have any problem understanding it.

Sub Sample()
    Dim ws As Worksheet
    Dim lRow As Long, lCol As Long
    Dim rng As Range

    '~~> Set this to the relevant worksheet
    Set ws = [Sheet1]

    With ws
        '~~> Get the last row and last column
        lRow = .Range("A" & .Rows.Count).End(xlUp).Row
        lCol = .Cells(1, .Columns.Count).End(xlToLeft).Column

        '~~> Set the range
        Set rng = .Range(.Cells(lRow, 1), .Cells(lRow, lCol))

        With rng
            Debug.Print .Address
            '
            '~~> What ever you want to do with the address
            '
        End With
    End With
End Sub

BTW I am assuming that LastRow is the same for all rows and same goes for the columns. If that is not the case then you will have use .Find to find the Last Row and the Last Column. You might want to see THIS

Assuming alphanumeric words, you can use:

Search  = ^([A-Za-z0-9]+)$
Replace = able:"\1"

Or, if you just want to highlight the lines and use "Replace All" & "In Selection" (with the same replace):

Search = ^(.+)$

^ points to the start of the line.
$ points to the end of the line.

\1 will be the source match within the parentheses.

As this is the closest I found to the issue I had, it's the first result that comes up and I didn't find an appropriate answer, I'll post the solution here for any future poor souls:

any() doesn't work where mocked class method uses a primitive parameter.

 public Boolean getResult(String identifier, boolean switch)

The above will produce the same exact issue as OP.

Solution, just wrap it:

 public Boolean getResult(String identifier, Boolean switch)

The latter solves the NPE.

Anyone have any good experience with a "port" of a database from SQL Server to MySQL?

This should be fairly painful! I switched versions of MySQL from 4.x to 5.x and various statements wouldn't work anymore as they used to. The query analyzer was "improved" so statements which previously were tuned for performance would not work anymore as expected.

The lesson learned from working with a 500GB MySQL database: It's a subtle topic and anything else but trivial!

Task is like a operation that you wanna perform , Thread helps to manage those operation through multiple process nodes. task is a lightweight option as Threading can lead to a complex code management

I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).

The only difference would be if you try to reassign it before the end of this very file.

I know its pretty old but I just encounter the problem and there is what I saw in the SQL doc :

[For best results when using BETWEEN with date or time values,] use CAST() to explicitly convert the values to the desired data type. Examples: If you compare a DATETIME to two DATE values, convert the DATE values to DATETIME values. If you use a string constant such as '2001-1-1' in a comparison to a DATE, cast the string to a DATE.

I assume it's better to use STR_TO_DATE since they took the time to make a function just for that and also the fact that i found this in the BETWEEN doc...

I use this little bash script to look at a blame history.

First parameter: file to look at

Subsequent parameters: Passed to git blame

#!/bin/bash
f=$1
shift
{ git log --pretty=format:%H -- "$f"; echo; } | {
  while read hash; do
    echo "--- $hash"
    git blame $@ $hash -- "$f" | sed 's/^/  /'
  done
}

You may supply blame-parameters like -L 70,+10 but it is better to use the regex-search of git blame because line-numbers typically "change" over time.

plt.gca().xaxis.grid(True) proved to be the solution for me

Simply pass your substring into the following line:

Outer HTML

document.documentElement.outerHTML.includes('substring')

Inner HTML

document.documentElement.innerHTML.includes('substring')

You can use these to search through the entire document and retrieve the tags that contain your search term:

function get_elements_by_inner(word) {
    res = []
    elems = [...document.getElementsByTagName('a')];
    elems.forEach((elem) => { 
        if(elem.outerHTML.includes(word)) {
            res.push(elem)
        }
    })
    return(res)
}

Usage:

How many times is the user "T3rm1" mentioned on this page?

get_elements_by_inner("T3rm1").length

1

How many times is jQuery mentioned?

get_elements_by_inner("jQuery").length

3

Get all elements containing the word "Cybernetic":

get_elements_by_inner("Cybernetic")

You need to re-factor the code into pieces. This doesn't stop execution, it just puts a delay in between the parts.

function partA() {
  ...
  window.setTimeout(partB,1000);
}

function partB() {
   ...
}

virtualenv permission problems might occur when you create the virtualenv as sudo and then operate without sudo in the virtualenv.

As found out in your question's comment, the solution here is to create the virtualenv without sudo to be able to work (esp. write) in it without sudo.

I learned all my Regex from this website: http://www.zytrax.com/tech/web/regex.htm. Google on 'Regex tutorials' and you'll find loads of helful articles.

String regex = "[a-zA-Z]*\.jpg";
System.out.println ("somthing.jpg".matches (regex));

returns true.

There are a lot of answers here that don't really address the basic fact that there's really NO WAY to do this predictably, and in a way that doesn't result you shooting yourself in the foot at some point in the future.

FragmentStatePagerAdapter is the only class that knows how to reliably access the fragments that are tracked by the FragmentManager - any attempt to try and guess the fragment's id or tag is not reliable, long-term. And attempts to track the instances manually will likely not work well when state is saved/restored, because FragmentStatePagerAdapter may well not call the callbacks when it restores the state.

About the only thing that I've been able to make work is copying the code for FragmentStatePagerAdapter and adding a method that returns the fragment, given a position (mFragments.get(pos)). Note that this method assumes that the fragment is actually available (i.e. it was visible at some point).

If you're particularly adventurous, you can use reflection to access the elements of the private mFragments list, but then we're back to square one (the name of the list is not guaranteed to stay the same).

I found this thread when I was searching for an answer to the same question. While I realize that it's a late answer, I thought I'd contribute it in case it's useful to anyone else:

The background-image can also be used to create an underline. This method handles line breaks.

It has to be shifted down via background-position and repeated horizontally. The line width can be adjusted to some degree using background-size (the background is limited to the content box of the element).

.underline
{
    --color: green;
    font-size: 40px;
    background-image: linear-gradient(var(--color) 0%, var(--color) 100%);
    background-repeat: repeat-x;
    background-position: 0 1.05em;
    background-size: 2px 5px;
}

<span class="underline">

I found interesting solution to get SSID of currently connected Wifi AP. You simply need to use iterate WifiManager.getConfiguredNetworks() and find configuration with specific WifiInfo.getNetworkId()

My example

in Broadcast receiver with action WifiManager.NETWORK_STATE_CHANGED_ACTION I'm getting current connection state from intent

NetworkInfo nwInfo = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
nwInfo.getState()

If NetworkInfo.getState is equal to NetworkInfo.State.CONNECTED then i can get current WifiInfo object

WifiManager wifiManager = (WifiManager) getSystemService (Context.WIFI_SERVICE);
WifiInfo info = wifiManager.getConnectionInfo ();

And after that

public String findSSIDForWifiInfo(WifiManager manager, WifiInfo wifiInfo) {

    List<WifiConfiguration> listOfConfigurations = manager.getConfiguredNetworks();

    for (int index = 0; index < listOfConfigurations.size(); index++) {
        WifiConfiguration configuration = listOfConfigurations.get(index);
        if (configuration.networkId == wifiInfo.getNetworkId()) {
            return configuration.SSID;
        }
    }

    return null;
}

And very important thing this method doesn't require Location nor Location Permisions

In API29 Google redesigned Wifi API so this solution is outdated for Android 10.

The database.yml is a file that is created with new rails applications in /config and defines the database configurations that your application will use in different environments. Read this for details.

Example database.yml:

development:
  adapter: sqlite3
  database: db/development.sqlite3
  pool: 5
  timeout: 5000

test:
  adapter: sqlite3
  database: db/test.sqlite3
  pool: 5
  timeout: 5000

production:
  adapter: mysql
  encoding: utf8
  database: your_db
  username: root
  password: your_pass
  socket: /tmp/mysql.sock
  host: your_db_ip     #defaults to 127.0.0.1
  port: 3306           

Use java.io.File.listFiles
Or
If you want to filter the list prior to iteration (or any more complicated use case), use apache-commons FileUtils. FileUtils.listFiles

you can use localStorage for storing the json data:

the example is given below:-

let JSONDatas = [
    {"id": "Open"},
    {"id": "OpenNew", "label": "Open New"},
    {"id": "ZoomIn", "label": "Zoom In"},
    {"id": "ZoomOut", "label": "Zoom Out"},
    {"id": "Find", "label": "Find..."},
    {"id": "FindAgain", "label": "Find Again"},
    {"id": "Copy"},
    {"id": "CopyAgain", "label": "Copy Again"},
    {"id": "CopySVG", "label": "Copy SVG"},
    {"id": "ViewSVG", "label": "View SVG"}
]

localStorage.setItem("datas", JSON.stringify(JSONDatas));

let data = JSON.parse(localStorage.getItem("datas"));

console.log(data);

Try this

on change event

$("#jodSel").on('change',function(){
    var getValue=$(this).val();
    alert(getValue);
  });

Note: In dropdownlist if you want to set id,text relation from your database then, set id as value in option tag, not by adding extra id attribute inside option its not standard paractise though i did both in my answer but i prefer example 1

HTML Markup

Example 1:
    <select id="example1">
        <option value="1">one</option>
        <option value="2">two</option>
        <option value="3">three</option>
        <option value="4">four</option>
    </select>
Example 2 :
    <select id="example2">
        <option id="1">one</option>
        <option id="2">two</option>
        <option id="3">three</option>
        <option id="4">four</option>
    </select>

Jquery:

$("#example1").on('change', function () {
    alert($(this).val());
});

$("#example2").on('change', function () {
    alert($(this).find('option:selected').attr('id'));
});

One the elements are added, use the rules method to add the rules

//bug fixed thanks to @Sparky
$('input[name^="fileupload"]').each(function () {
    $(this).rules('add', {
        required: true,
        accept: "image/jpeg, image/pjpeg"
    })
})

Demo: Fiddle

Update

var filenumber = 1;
$("#AddFile").click(function () { //User clicks button #AddFile
    var $li = $('<li><input type="file" name="FileUpload' + filenumber + '" id="FileUpload' + filenumber + '" required=""/> <a href="#" class="RemoveFileUpload">Remove</a></li>').prependTo("#FileUploader");

    $('#FileUpload' + filenumber).rules('add', {
        required: true,
        accept: "image/jpeg, image/pjpeg"
    })

    filenumber++;
    return false;
});

There is some performance issue regarding to marshaling and unmarshaling. Parcelable is twice faster than Serializable.

If you want two classes on one element, do it this way:

<div class="social first"></div>

Reference it in css like so:

There are four ways to show queries:

1. This will show the last query executed of user model:

   debug($this->User->lastQuery());  
   

2. This will show all executed query of user model:

   $log = $this->User->getDataSource()->getLog(false, false);       
   debug($log);
   

3. This will show a log of all queries:

   $db =& ConnectionManager::getDataSource('default');
   $db->showLog();
   

4. If you want to show all queries log all over the application you can use in view/element/filename.ctp.

   <?php echo $this->element('sql_dump'); ?>
   

You can use mx.DateTime module

import mx.DateTime as mt

t1 = mt.now() 
t2 = mt.now()
print int((t2-t1).seconds)

Well maybe a little late after 4 years haha... but I was looking for solution to do OBJECT to CSV, however most solutions here is actually for ARRAY to CSV...

After some tinkering, here is my solution to convert object into CSV, I think is pretty neat. Hope this would help someone else.

$resp = array();
foreach ($entries as $entry) {
    $row = array();
    foreach ($entry as $key => $value) {
        array_push($row, $value);
    }
    array_push($resp, implode(',', $row));
}
echo implode(PHP_EOL, $resp);

Note that for the $key => $value to work, your object's attributes must be public, the private ones will not get fetched.

The end result is that you get something like this:

blah,blah,blah
blah,blah,blah

If you need to remove text inside nested parentheses, too, then:

        var prevStr;
        do {
            prevStr = str;
            str = str.replace(/\([^\)\(]*\)/, "");
        } while (prevStr != str);

There is no builtin feature to wait for any process to finish.

You could send kill -0 to any PID found, so you don't get puzzled by zombies and stuff that will still be visible in ps (while still retrieving the PID list using ps).

If you need the result in a date format you can use:

Select Convert(DateTime, Convert(VarChar, GetDate(), 101))

Instead of playing around with onCloseRequest handlers or window events, I prefer calling Platform.setImplicitExit(true) the beginning of the application.

According to JavaDocs:

"If this attribute is true, the JavaFX runtime will implicitly shutdown when the last window is closed; the JavaFX launcher will call the Application.stop() method and terminate the JavaFX application thread."

Example:

@Override
void start(Stage primaryStage) {
    Platform.setImplicitExit(true)
    ...
    // create stage and scene
}

it could be JDK combinations issue or JDK version issue select proper one. i am using combination of 64-bit Operating System, 64-bit JDK, 64-bit Eclipse IDE.

It's not a big deal on a small/personal scale, but it can become a bigger deal quickly on a larger scale. My employer is a large Microsoft shop, but won't/can't buy into Team System/TFS for a number of reasons. We currently use Subversion + Orcas + MBUnit + TestDriven.NET and it works well, but getting TD.NET was a huge hassle. The version sensitivity of MBUnit + TestDriven.NET is also a big hassle, and having one additional commercial thing (TD.NET) for legal to review and procurement to handle and manage, isn't trivial. My company, like a lot of companies, are fat and happy with a MSDN Subscription model, and it's just not used to handling one off procurements for hundreds of developers. In other words, the fully integrated MS offer, while definitely not always best-of-bread, is a significant value-add in my opinion.

I think we'll stay with our current step because it works and we've already gotten over the hump organizationally, but I sure do wish MS had a compelling offering in this space so we could consolidate and simplify our dev stack a bit.

When writing CMake scripts there is a lot you need to know about the syntax and how to use variables in CMake.

The Syntax

Strings using set():

• set(MyString "Some Text")
• set(MyStringWithVar "Some other Text: ${MyString}")
• set(MyStringWithQuot "Some quote: \"${MyStringWithVar}\"")

Or with string():

• string(APPEND MyStringWithContent " ${MyString}")

Lists using set():

• set(MyList "a" "b" "c")
• set(MyList ${MyList} "d")

Or better with list():

• list(APPEND MyList "a" "b" "c")
• list(APPEND MyList "d")

Lists of File Names:

• set(MySourcesList "File.name" "File with Space.name")
• list(APPEND MySourcesList "File.name" "File with Space.name")
• add_excutable(MyExeTarget ${MySourcesList})

The Documentation

• CMake/Language Syntax
• CMake: Variables Lists Strings
• CMake: Useful Variables
• CMake set() Command
• CMake string()Command
• CMake list() Command
• Cmake: Generator Expressions

The Scope or "What value does my variable have?"

First there are the "Normal Variables" and things you need to know about their scope:

• Normal variables are visible to the CMakeLists.txt they are set in and everything called from there (add_subdirectory(), include(), macro() and function()).
• The add_subdirectory() and function() commands are special, because they open-up their own scope.
  • Meaning variables set(...) there are only visible there and they make a copy of all normal variables of the scope level they are called from (called parent scope).
  • So if you are in a sub-directory or a function you can modify an already existing variable in the parent scope with set(... PARENT_SCOPE)
  • You can make use of this e.g. in functions by passing the variable name as a function parameter. An example would be function(xyz _resultVar) is setting set(${_resultVar} 1 PARENT_SCOPE)
• On the other hand everything you set in include() or macro() scripts will modify variables directly in the scope of where they are called from.

Second there is the "Global Variables Cache". Things you need to know about the Cache:

• If no normal variable with the given name is defined in the current scope, CMake will look for a matching Cache entry.
• Cache values are stored in the CMakeCache.txt file in your binary output directory.

• The values in the Cache can be modified in CMake's GUI application before they are generated. Therefore they - in comparison to normal variables - have a type and a docstring. I normally don't use the GUI so I use set(... CACHE INTERNAL "") to set my global and persistant values.

  Please note that the INTERNAL cache variable type does imply FORCE

• In a CMake script you can only change existing Cache entries if you use the set(... CACHE ... FORCE) syntax. This behavior is made use of e.g. by CMake itself, because it normally does not force Cache entries itself and therefore you can pre-define it with another value.

• You can use the command line to set entries in the Cache with the syntax cmake -D var:type=value, just cmake -D var=value or with cmake -C CMakeInitialCache.cmake.
• You can unset entries in the Cache with unset(... CACHE).

The Cache is global and you can set them virtually anywhere in your CMake scripts. But I would recommend you think twice about where to use Cache variables (they are global and they are persistant). I normally prefer the set_property(GLOBAL PROPERTY ...) and set_property(GLOBAL APPEND PROPERTY ...) syntax to define my own non-persistant global variables.

Variable Pitfalls and "How to debug variable changes?"

To avoid pitfalls you should know the following about variables:

• Local variables do hide cached variables if both have the same name
• The find_... commands - if successful - do write their results as cached variables "so that no call will search again"
• Lists in CMake are just strings with semicolons delimiters and therefore the quotation-marks are important
  • set(MyVar a b c) is "a;b;c" and set(MyVar "a b c") is "a b c"
  • The recommendation is that you always use quotation marks with the one exception when you want to give a list as list
  • Generally prefer the list() command for handling lists
• The whole scope issue described above. Especially it's recommended to use functions() instead of macros() because you don't want your local variables to show up in the parent scope.
• A lot of variables used by CMake are set with the project() and enable_language() calls. So it could get important to set some variables before those commands are used.
• Environment variables may differ from where CMake generated the make environment and when the the make files are put to use.
  • A change in an environment variable does not re-trigger the generation process.
  • Especially a generated IDE environment may differ from your command line, so it's recommended to transfer your environment variables into something that is cached.

Sometimes only debugging variables helps. The following may help you:

• Simply use old printf debugging style by using the message() command. There also some ready to use modules shipped with CMake itself: CMakePrintHelpers.cmake, CMakePrintSystemInformation.cmake
• Look into CMakeCache.txt file in your binary output directory. This file is even generated if the actual generation of your make environment fails.
• Use variable_watch() to see where your variables are read/written/removed.
• Look into the directory properties CACHE_VARIABLES and VARIABLES
• Call cmake --trace ... to see the CMake's complete parsing process. That's sort of the last reserve, because it generates a lot of output.

Special Syntax

• Environment Variables
  • You can can read $ENV{...} and write set(ENV{...} ...) environment variables
• Generator Expressions
  • Generator expressions $<...> are only evaluated when CMake's generator writes the make environment (it comparison to normal variables that are replaced "in-place" by the parser)
  • Very handy e.g. in compiler/linker command lines and in multi-configuration environments
• References
  • With ${${...}} you can give variable names in a variable and reference its content.
  • Often used when giving a variable name as function/macro parameter.
• Constant Values (see if() command)
  • With if(MyVariable) you can directly check a variable for true/false (no need here for the enclosing ${...})
  • True if the constant is 1, ON, YES, TRUE, Y, or a non-zero number.
  • False if the constant is 0, OFF, NO, FALSE, N, IGNORE, NOTFOUND, the empty string, or ends in the suffix -NOTFOUND.
  • This syntax is often use for something like if(MSVC), but it can be confusing for someone who does not know this syntax shortcut.
• Recursive substitutions
  • You can construct variable names using variables. After CMake has substituted the variables, it will check again if the result is a variable itself. This is very powerful feature used in CMake itself e.g. as sort of a template set(CMAKE_${lang}_COMPILER ...)
  • But be aware this can give you a headache in if() commands. Here is an example where CMAKE_CXX_COMPILER_ID is "MSVC" and MSVC is "1":
    • if("${CMAKE_CXX_COMPILER_ID}" STREQUAL "MSVC") is true, because it evaluates to if("1" STREQUAL "1")
    • if(CMAKE_CXX_COMPILER_ID STREQUAL "MSVC") is false, because it evaluates to if("MSVC" STREQUAL "1")
    • So the best solution here would be - see above - to directly check for if(MSVC)
  • The good news is that this was fixed in CMake 3.1 with the introduction of policy CMP0054. I would recommend to always set cmake_policy(SET CMP0054 NEW) to "only interpret if() arguments as variables or keywords when unquoted."
• The option() command
  • Mainly just cached strings that only can be ON or OFF and they allow some special handling like e.g. dependencies
  • But be aware, don't mistake the option with the set command. The value given to option is really only the "initial value" (transferred once to the cache during the first configuration step) and is afterwards meant to be changed by the user through CMake's GUI.

With Java 7's try-with-resources Jiri's answer can be improved upon:

try (BufferedReader br = new BufferedReader(new FileReader("foo.txt"))) {
   String line = null;
   while ((line = br.readLine()) != null) {
       System.out.println(line);
   }
}

Add exception handling at the place of your choice, either in this try or elsewhere.

Add:

fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
proxy_buffer_size   128k;
proxy_buffers   4 256k;

Works for me.

The best that I've been able to do is

$(this).closest('.modal').modal('toggle');

This gets the modal holding the DOM object you triggered the event on (guessing you're clicking a button). Gets the closest parent '.modal' and toggles it. Obviously only works because it's inside the modal you clicked.

You can however do this:

$(".modal:visible").modal('toggle');

This gets the modal that is displaying (since you can only have one open at a time), and triggers the 'toggle' This would not work without ":visible"

so it's probably not for creating instances of object

It's used exactly for that. You define a function constructor like so:

function Person(name) {
    this.name = name;
}

var john = new Person('John');

However the extra benefit that ECMAScript has is you can extend with the .prototype property, so we can do something like...

Person.prototype.getName = function() { return this.name; }

All objects created from this constructor will now have a getName because of the prototype chain that they have access to.

Your have dropped the Project in your workspace, and then trying to import it, that's the problem.

This has two solutions:

1. More your project folder outside your workspace in some other location and then try.

2. Go to File ---> new Project ---> Select the existing project radio button ---> browse to the project folder in your workspace ---> finish

Edited

Assume D:\MyDirectory\MyWorkSpace - Path of your WorkSpace

Drop your project which you want to import in Eclipse in MyDirectory folder Not in MyWorkSpace, and try.

yup.. here's my code:

<style>
  .circle{
     width: 100px;
     height: 100px;
     border-radius: 50%;
     background-color: blue
  }
</style>
<div class="circle">
</div>

Yes, you can create objects using reflection. For example, String.class.newInstance() will give you a new empty String object.

char_seen = []
for char in string:
    if char not in char_seen:
        char_seen.append(char)
print(''.join(char_seen))

This will preserve the order in which alphabets are coming,

output will be

abcd

If you want only the email clients you should use android.content.Intent.EXTRA_EMAIL with an array. Here goes an example:

final Intent result = new Intent(android.content.Intent.ACTION_SEND);
result.setType("plain/text");
result.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] { recipient });
result.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
result.putExtra(android.content.Intent.EXTRA_TEXT, body);

They are not identical. Memcache is older but it has some limitations. I was using just fine in my application until I realized you can't store literal FALSE in cache. Value FALSE returned from the cache is the same as FALSE returned when a value is not found in the cache. There is no way to check which is which. Memcached has additional method (among others) Memcached::getResultCode that will tell you whether key was found.

Because of this limitation I switched to storing empty arrays instead of FALSE in cache. I am still using Memcache, but I just wanted to put this info out there for people who are deciding.

In addition to Christopher's answer.

If you need to count total size of versioned bucket use:

aws s3api list-object-versions --bucket BUCKETNAME --output json --query "[sum(Versions[].Size)]"

It counts both Latest and Archived versions.

Sending email programmatically with Kotlin.

• simple email sending, not all the other features (like attachments).
• TLS is always on
• Only 1 gradle email dependency needed also.

I also found this list of email POP services really helpful:

How to use:

    val auth = EmailService.UserPassAuthenticator("yourUser", "yourPass")
    val to = listOf(InternetAddress("[email protected]"))
    val from = InternetAddress("[email protected]")
    val email = EmailService.Email(auth, to, from, "Test Subject", "Hello Body World")
    val emailService = EmailService("yourSmtpServer", 587)

    GlobalScope.launch { // or however you do background threads
        emailService.send(email)
    }

The code:

                //setContent(email.htmlBody, "text/html; charset=UTF-8")
            })
        })
        Transport.send(msg)
    }

    companion object {
        const val CLIENT_NAME = "Android StackOverflow programmatic email"

And here is a quick benchmark for both #sample and #rand:

irb(main):014:0* Benchmark.bm do |x|
irb(main):015:1*   x.report('sample') { 1_000_000.times { (1..100).to_a.sample } }
irb(main):016:1>   x.report('rand') { 1_000_000.times { rand(1..100) } }
irb(main):017:1> end
       user     system      total        real
sample  3.870000   0.020000   3.890000 (  3.888147)
rand  0.150000   0.000000   0.150000 (  0.153557)

So, doing rand(a..b) is the right thing

I find, if the data is imported, you may need to use the trim command on top of it, to get your details. =LEFT(TRIM(B2),8) In my case, I was using it to find a IP range. 10.3.44.44 with mask 255.255.255.0, so response is: 10.3.44 Kind of handy.

I fixed this problem by increasing the amount of memory available to the vagrant VM where the database was located.

For enter event handling you can use

1. @keyup.enter or
2. @keyup.13

13 is the keycode of enter. For @ key event, the keycode is 50. So you can use @keyup.50.

For example:

<input @keyup.50="atPress()" />

The first thing you need to understand is that when you pass something to a function, that something is copied to the function's arguments.

Suppose you have the following:

void swap1(int a, int b) {
    int temp = a;
    a = b;
    b = temp;
    assert(a == 17);
    assert(b == 42);
    // they're swapped!
}

int x = 42;
int y = 17;
swap1(x, y);
assert(x == 42);
assert(y == 17);
// no, they're not swapped!

The original variables will not be swapped, because their values are copied into the function's arguments. The function then proceeds to swap the values of those arguments, and then returns. The original values are not changed, because the function only swaps its own private copies.

Now how do we work around this? The function needs a way to refer to the original variables, not copies of their values. How can we refer to other variables in C? Using pointers.

If we pass pointers to our variables into the function, the function can swap the values in our variables, instead of its own argument copies.

void swap2(int* a, int* b) {
    int temp = *a;
    *a = *b;
    *b = temp;
    assert(*a == 17);
    assert(*b == 42);
    // they're swapped!
}

int x = 42;
int y = 17;
swap2(&x, &y); // give the function pointers to our variables
assert(x == 17);
assert(y == 42);
// yes, they're swapped!

Notice how inside the function we're not assigning to the pointers, but assigning to what they point to. And the pointers point to our variables x and y. The function is changing directly the values stored in our variables through the pointers we give it. And that's exactly what we needed.

Now what happens if we have two pointer variables and want to swap the pointers themselves (as opposed to the values they point to)? If we pass pointers, the pointers will simply be copied (not the values they point to) to the arguments.

void swap3(int* a, int* b) {
    int* temp = a;
    a = b;
    b = temp;
    assert(*a == 17);
    assert(*b == 42);
    // they're swapped!
}
void swap4(int* a, int* b) {
    int temp = *a;
    *a = *b;
    *b = temp;
    assert(*a == 17);
    assert(*b == 42);
    // they're swapped!
}

int x = 42;
int y = 17;
int* xp = &x;
int* yp = &y;
swap3(xp, yp);
assert(xp == &x);
assert(yp == &y);
assert(x == 42);
assert(y == 17);
// Didn't swap anything!
swap4(xp, yp);
assert(xp == &x);
assert(yp == &y);
assert(x == 17);
assert(y == 42);
// Swapped the stored values instead!

The function swap3 only swaps its own private copies of our pointers that it gets in its arguments. It's the same issue we had with swap1. And swap4 is changing the values our variables point to, not the pointers! We're giving the function a means to refer to the variables x and y but we want them to refer to xp and yp.

How do we do that? We pass it their addresses!

void swap5(int** a, int** b) {
    int* temp = *a;
    *a = *b;
    *b = temp;
    assert(**a == 17);
    assert(**b == 42);
    // they're swapped!
}


int x = 42;
int y = 17;
int* xp = &x;
int* yp = &y;
swap5(&xp, &yp);
assert(xp == &y);
assert(yp == &x);
assert(x == 42);
assert(y == 17);
// swapped only the pointers variables

This way it swaps our pointer variables (notice how xp now points to y) but not the values they point to. We gave it a way to refer to our pointer variables, so it can change them!

By now it should be easy to understand how to swap two strings in the form of char* variables. The swap function needs to receive pointers to char*.

void swapStrings(char** a, char** b){
    char *temp = *a;
    *a = *b;
    *b = temp;
    assert(strcmp(*a, "world") == 0);
    assert(strcmp(*b, "Hello") == 0);
}

char* x = "Hello";
char* y = "world";
swapStrings(&x, &y);
assert(strcmp(x, "world") == 0);
assert(strcmp(y, "Hello") == 0);

Your query should work for synonyms as well as the tables. However, you seem to expect indexes on views where there are not. Maybe is it materialized views ?

Try the following code. The value you are looking for is stored on a GuidAttribute instance attached to the Assembly

using System.Runtime.InteropServices;

static void Main(string[] args)
{
    var assembly = typeof(Program).Assembly;
    var attribute = (GuidAttribute)assembly.GetCustomAttributes(typeof(GuidAttribute),true)[0];
    var id = attribute.Value;
    Console.WriteLine(id);
}

Please use regex to remove anything before |

example

dsfdf | fdfsfsf
dsdss|gfghhghg
dsdsds |dfdsfsds

Use find and replace in notepad++

find: .+(\|) replace: \1

output

| fdfsfsf
|gfghhghg
|dfdsfsds

Thanks for your replies. Here's what I did:

git gc
git gc --aggressive
git prune

That seemed to have done the trick. I started with around 10.5MB and now it's little more than 980KBs.

Sounds like an error you would get when your forms authentication ticket has expired. What is the timeout period for your ticket? Is it set to sliding or absolute expiration?

I believe the default for the timeout is 20 minutes with sliding expiration so if a user gets authenticated and at some point doesn't hit your site for 20 minutes their ticket would be expired. If it is set to absolute expiration it will expire X number of minutes after it was issued where X is your timeout setting.

You can set the timeout and expiration policy (e.g. sliding, absolute) in your web/machine.config under /configuration/system.web/authentication/forms

I know this is a little late, but my favoured method for doing this is netcat, as you get exactly what curl sent; this can differ from the --trace or --trace-ascii options which won't show non-ASCII characters properly (they just show as dots or need to be decoded).

You can do this as very easily by opening two terminal windows, in the first type:

nc -l localhost 12345

This opens a listening process on port 12345 of your local machine.

In the second terminal window enter your curl command, for example:

curl --form 'foo=bar' localhost:12345

In the first terminal window you will see exactly what curl sent in the request.

Now of course nc won't send anything in response (unless you type it in yourself), so you will need to interrupt the curl command (control-c) and repeat the process for each test.

However, this is a useful option for simply debugging your request, as you're not involving a round-trip anywhere, or producing bogus, iterative requests somewhere until you get it right; once you're happy with the command, simply redirect it to a valid URL and you're good to go.

You can do the same for any cURL library as well, simply edit your request to point to the local nc listener until you're happy with it.

I think that the problem is that you do not have a proper view controller hierarchy. Set the rootviewcontroller of the app and then show new views by pushing or presenting new view controllers on them. Let each view controller manage their views. Only container view controllers, like the tabbarviewcontroller, should ever add other view controllers views to their own views. Read the view controllers programming guide to learn more on how to use view controllers properly. https://developer.apple.com/library/content/featuredarticles/ViewControllerPGforiPhoneOS/

The getDrawable (int id) method is deprecated as of API 22.

Instead you should use the getDrawable (int id, Resources.Theme theme) for API 21+

Code would look something like this.

Drawable myDrawable;
if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
    myDrawable = context.getResources().getDrawable(id, context.getTheme());
} else {
    myDrawable = context.getResources().getDrawable(id);
}

Following up on Mark's answer, if you're not using Jupyter for some reason, e.g. you want to do some quick testing on the console, you can use the DataFrame.to_string method, which works from -- at least -- Pandas 0.12 (2014) onwards.

import pandas as pd

matrix = [(1, 23, 45), (789, 1, 23), (45, 678, 90)]
df = pd.DataFrame(matrix, columns=list('abc'))
print(df.to_string())

#  outputs:
#       a    b   c
#  0    1   23  45
#  1  789    1  23
#  2   45  678  90

for iphones safari up to iOS 10 "viewport" is not a solution, i don't like this way, but i have used this javascript code and it helped me

 document.addEventListener('touchmove', function(event) {
    event = event.originalEvent || event;
    if(event.scale > 1) {
      event.preventDefault();
    }
  }, false);

In case anyone still hunting the cause of this hateful issue, there comes a solution to nail the causing file. https://www.drupal.org/node/1622904#comment-10768958 from Drupal community.

And I quote:

Edit

includes/bootstrap.inc:

function drupal_load(). It is a short function. Find following line: include_once DRUPAL_ROOT . '/' . $filename; Temporarily replace it by

ob_start();
include_once DRUPAL_ROOT . '/' . $filename;
$value = ob_get_contents();
ob_end_clean();
if ($value !== '') {
  $filename = check_plain($filename);
  $value = check_plain($value);

If you're using Django's built-in LoginView, it takes next as context, which is "The URL to redirect to after successful login. This may contain a query string, too." (see docs)

Also from the docs:

"If login is successful, the view redirects to the URL specified in next. If next isn’t provided, it redirects to settings.LOGIN_REDIRECT_URL (which defaults to /accounts/profile/)."

Example code:

urls.py

from django.urls import path
from django.contrib.auth import views as auth_views

from account.forms import LoginForm # optional form to pass to view


urlpatterns = [
    ...

    # --------------- login url/view -------------------
    path('account/login/', auth_views.LoginView.as_view(
        template_name='login.html',  
        authentication_form=LoginForm, 
        extra_context={ 

            # option 1: provide full path
            'next': '/account/my_custom_url/', 

            # option 2: just provide the name of the url
            # 'next': 'custom_url_name',  
        },
    ), name='login'),

    ...
]

login.html

...

<form method="post" action="{% url 'login' %}">

  ...

  {# option 1 #}
  <input type="hidden" name="next" value="{{ next }}">

  {# option 2 #}
  {# <input type="hidden" name="next" value="{% url next %}"> #}

</form>

1. Open your favorite text editor
2. Create a new file named whatever.h
3. Put your function prototypes in it

DONE.

Example whatever.h

#ifndef WHATEVER_H_INCLUDED
#define WHATEVER_H_INCLUDED
int f(int a);
#endif

Note: include guards (preprocessor commands) added thanks to luke. They avoid including the same header file twice in the same compilation. Another possibility (also mentioned on the comments) is to add #pragma once but it is not guaranteed to be supported on every compiler.

Example whatever.c

#include "whatever.h"

int f(int a) { return a + 1; }

And then you can include "whatever.h" into any other .c file, and link it with whatever.c's object file.

Like this:

sample.c

#include "whatever.h"

int main(int argc, char **argv)
{
    printf("%d\n", f(2)); /* prints 3 */
    return 0;
}

To compile it (if you use GCC):

$ gcc -c whatever.c -o whatever.o
$ gcc -c sample.c -o sample.o

To link the files to create an executable file:

$ gcc sample.o whatever.o -o sample

You can test sample:

$ ./sample
3
$

If you are trying to "Submit and Reset" the the "form" with one Button click, Try this!

Here I have used jQuery function, it can be done by simple JavaScript also...

        <form id="form_data">
           <input type="anything"  name="anything" />
           <input type="anything"  name="anything" />

             <!-- Save and Reset button -->
           <button type="button" id="btn_submit">Save</button>
           <button type="reset" id="btn_reset" style="display: none;"></button>
        </form>

<script type="text/javascript">
$(function(){
    $('#btn_submit').click(function(){
        // Do what ever you want
       $('#btn_reset').click();  // Clicking reset button
    });
});
</script>

Add following gems in your gem file

gem 'therubyracer'
gem 'execjs'

and run

bundle install

OR

Install Node.js to fix it permanently for all projects.

I would recommend you well tested PHP library: curl-easy

<?php
$request = new cURL\Request('http://www.externalsite.com/script2.php?variable=45');
$request->getOptions()
    ->set(CURLOPT_TIMEOUT, 5)
    ->set(CURLOPT_RETURNTRANSFER, true);

// add callback when the request will be completed
$request->addListener('complete', function (cURL\Event $event) {
    $response = $event->response;
    $content = $response->getContent();
    echo $content;
});

while ($request->socketPerform()) {
    // do anything else when the request is processed
}

You can also use RedirectMatch directive to deny access to a folder.

To deny access to a folder, you can use the following RedirectMatch in htaccess :

 RedirectMatch 403 ^/folder/?$

This will forbid an external access to /folder/ eg : http://example.com/folder/ will return a 403 forbidden error.

To deny access to everything inside the folder, You can use this :

RedirectMatch 403 ^/folder/.*$

This will block access to the entire folder eg : http://example.com/folder/anyURI will return a 403 error response to client.

Instead of relying on the default virtual host mechanism in apache, you can define one last catchall virtualhost that uses an arbitrary ServerName and a wildcard ServerAlias, e.g.

ServerName catchall.mydomain.com
ServerAlias *.mydomain.com

In that way you can use SNI and apache will not send back the SSL warning.

Of course, this only works if you can describe all of your domains easily using a wildcard syntax.

I was getting this error and none of the responses was my case, it might help someone googling:

I was defining a Proptype wrong:

ids: PropTypes.array(PropTypes.string)

It should be:

ids: PropTypes.arrayOf(PropTypes.string)

VSCode and the compile error didnt give me a correct hint.

async and await are syntactic sugars. The essence of async and await is state machine. The compiler will transform your async/await code into a state machine.

At the same time, in order for async/await to be really practicable in real projects, we need to have lots of Async I/O library functions already in place. For C#, most original synchronized I/O functions has an alternative Async version. The reason we need these Async functions is because in most cases, your own async/await code will boil down to some library Async method.

The Async version library functions in C# is kind of like the AsynchronousChannel concept in Java. For example, we have AsynchronousFileChannel.read which can either return a Future or execute a callback after the read operation is done. But it’s not exactly the same. All C# Async functions return Tasks (similar to Future but more powerful than Future).

So let’s say Java do support async/await, and we write some code like this:

public static async Future<Byte> readFirstByteAsync(String filePath) {
    Path path = Paths.get(filePath);
    AsynchronousFileChannel channel = AsynchronousFileChannel.open(path);

    ByteBuffer buffer = ByteBuffer.allocate(100_000);
    await channel.read(buffer, 0, buffer, this);
    return buffer.get(0);
}

Then I would imagine the compiler will transform the original async/await code into something like this:

public static Future<Byte> readFirstByteAsync(String filePath) {

    CompletableFuture<Byte> result = new CompletableFuture<Byte>();

    AsyncHandler ah = new AsyncHandler(result, filePath);

    ah.completed(null, null);

    return result;
}

And here is the implementation for AsyncHandler:

class AsyncHandler implements CompletionHandler<Integer, ByteBuffer>
{
    CompletableFuture<Byte> future;
    int state;
    String filePath;

    public AsyncHandler(CompletableFuture<Byte> future, String filePath)
    {
        this.future = future;
        this.state = 0;
        this.filePath = filePath;
    }

    @Override
    public void completed(Integer arg0, ByteBuffer arg1) {
        try {
            if (state == 0) {
                state = 1;
                Path path = Paths.get(filePath);
                AsynchronousFileChannel channel = AsynchronousFileChannel.open(path);

                ByteBuffer buffer = ByteBuffer.allocate(100_000);
                channel.read(buffer, 0, buffer, this);
                return;
            } else {
                Byte ret = arg1.get(0);
                future.complete(ret);
            }

        } catch (Exception e) {
            future.completeExceptionally(e);
        }
    }

    @Override
    public void failed(Throwable arg0, ByteBuffer arg1) {
        future.completeExceptionally(arg0);
    }
}

For picking just one element of a generator use break in a for statement, or list(itertools.islice(gen, 1))

According to your example (literally) you can do something like:

while True:
  ...
  if something:
      for my_element in myfunct():
          dostuff(my_element)
          break
      else:
          do_generator_empty()

If you want "get just one element from the [once generated] generator whenever I like" (I suppose 50% thats the original intention, and the most common intention) then:

gen = myfunct()
while True:
  ...
  if something:
      for my_element in gen:
          dostuff(my_element)
          break
      else:
          do_generator_empty()

This way explicit use of generator.next() can be avoided, and end-of-input handling doesn't require (cryptic) StopIteration exception handling or extra default value comparisons.

The else: of for statement section is only needed if you want do something special in case of end-of-generator.

Note on next() / .next():

In Python3 the .next() method was renamed to .__next__() for good reason: its considered low-level (PEP 3114). Before Python 2.6 the builtin function next() did not exist. And it was even discussed to move next() to the operator module (which would have been wise), because of its rare need and questionable inflation of builtin names.

Using next() without default is still very low-level practice - throwing the cryptic StopIteration like a bolt out of the blue in normal application code openly. And using next() with default sentinel - which best should be the only option for a next() directly in builtins - is limited and often gives reason to odd non-pythonic logic/readablity.

Bottom line: Using next() should be very rare - like using functions of operator module. Using for x in iterator , islice, list(iterator) and other functions accepting an iterator seamlessly is the natural way of using iterators on application level - and quite always possible. next() is low-level, an extra concept, unobvious - as the question of this thread shows. While e.g. using break in for is conventional.

(parseFloat('2.3') + parseFloat('2.4')).toFixed(1);

its going to give you solution i suppose

The question, is the provided example just an "example" or exact what you looking for? There are many mixed answers here, and I dont understand the complexibility of the accepted one.

To find out if ANY content of the array of needles exists in the string, and quickly return true or false:

$string = 'abcdefg';

if(str_replace(array('a', 'c', 'd'), '', $string) != $string){
    echo 'at least one of the needles where found';
};

If, so, please give @Leon credit for that.

To find out if ALL values of the array of needles exists in the string, as in this case, all three 'a', 'b' and 'c' MUST be present, like you mention as your "for example"

echo 'All the letters are found in the string!';

Many answers here is out of that context, but I doubt that the intension of the question as you marked as resolved. E.g. The accepted answer is a needle of

$array  = array('burger', 'melon', 'cheese', 'milk');

What if all those words MUST be found in the string?

Then you try out some "not accepted answers" on this page.

In addition to previous answers, if your menu items are Categories and you want to highlight them when navigating through posts, check also for current-post-ancestor:

add_filter('nav_menu_css_class' , 'special_nav_class' , 10 , 2);

function special_nav_class ($classes, $item) {
    if (in_array('current-post-ancestor', $classes) || in_array('current-page-ancestor', $classes) || in_array('current-menu-item', $classes) ){
        $classes[] = 'active ';
    }
    return $classes;
}

You need to first add using Microsoft.Win32; to your code page.

Then you can begin to use the Registry classes:

try
{
    using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\\Wow6432Node\\MySQL AB\\MySQL Connector\\Net"))
    {
        if (key != null)
        {
            Object o = key.GetValue("Version");
            if (o != null)
            {
                Version version = new Version(o as String);  //"as" because it's REG_SZ...otherwise ToString() might be safe(r)
                //do what you like with version
            }
        }
    }
}
catch (Exception ex)  //just for demonstration...it's always best to handle specific exceptions
{
    //react appropriately
}

BEWARE: unless you have administrator access, you are unlikely to be able to do much in LOCAL_MACHINE. Sometimes even reading values can be a suspect operation without admin rights.

Additional relevant info: A common need is to pass the ID of the object represented by the marker to some ajax call for the purpose of fetching more info from the server.

It seems that when we do:

marker.on('click', function(e) {...

The e points to a MouseEvent, which does not let us get to the marker object. But there is a built-in this object which strangely, requires us to use this.options to get to the options object which let us pass anything we need. In the above case, we can pass some ID in an option, let's say objid then within the function above, we can get the value by invoking: this.options.objid

You could define a name for the VLOOKUP part of the formula.

1. Highlight the cell that contains this formula
2. On the Insert menu, go Name, and click Define
3. Enter a name for your variable (e.g. 'Value')
4. In the Refers To box, enter your VLOOKUP formula: =VLOOKUP(A1,B:B, 1, 0)
5. Click Add, and close the dialog
6. In your original formula, replace the VLOOKUP parts with the name you just defined: =IF( Value > 10, Value - 10, Value )

Step (1) is important here: I guess on the second row, you want Excel to use VLOOKUP(A2,B:B, 1, 0), the third row VLOOKUP(A3,B:B, 1, 0), etc. Step (4) achieves this by using relative references (A1 and B:B), not absolute references ($A$1 and $B:$B).

Note:

1. For newer Excel versions with the ribbon, go to Formulas ribbon -> Define Name. It's the same after that. Also, to use your name, you can do "Use in Formula", right under Define Name, while editing the formula, or else start typing it, and Excel will suggest the name (credits: Michael Rusch)

2. Shortened steps: 1. Right click a cell and click Define name... 2. Enter a name and the formula which you want to associate with that name/local variable 3. Use variable (credits: Jens Bodal)

I have observed on Windows 2008 the Windows Error Reporting crash dumps get staged in the folder:

C:\Users\All Users\Microsoft\Windows\WER\ReportQueue

Which, starting with Windows Vista, is an alias for:

C:\ProgramData\Microsoft\Windows\WER\ReportQueue

compiler gives error because when assigning mValue=0 compiler find assignment operator=(int ) for compile time binding but it's not present in the string class. if we type cast following statement to char like mValue=(char)0 then its compile successfully because string class contain operator=(char) method.

I have used below line of code and it works, Try this

DataTable dt =  dataSource.Tables[0];

form comment of JStrahl format(as.Date(df$date),"%w"), we get number of current day : as.numeric(format(as.Date("2016-05-09"),"%w"))

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

Markup

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

Code

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

Demo Here

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

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

Sometimes when you download plugins you may get (.zip) files then just rename with (.hpi) and then extract all the plugins and move to <jenkinsHome>/plugins/ directory.

This will show the 10th line of myfile.txt:

get-content myfile.txt | select -first 1 -skip 9

both -first and -skip are optional parameters, and -context, or -last may be useful in similar situations.

The main difference between return false and event.preventDefault() is that your code below return false will not be executed and in event.preventDefault() case your code will execute after this statement.

When you write return false it do the following things for you behind the scenes.

* Stops callback execution and returns immediately when called.
* event.stopPropagation();
* event.preventDefault();

This is my solution with prepared statements and stored procedure is returning several rows not only one value.

<?php

require 'config.php';
header('Content-type:application/json');
$connection->set_charset('utf8');

$mIds = $_GET['ids'];

$stmt = $connection->prepare("CALL sp_takes_string_returns_table(?)");
$stmt->bind_param("s", $mIds);

$stmt->execute();

$result = $stmt->get_result();
$response = $result->fetch_all(MYSQLI_ASSOC);
echo json_encode($response);

$stmt->close();
$connection->close();

Richard, next time, you should add this code under TextView at the layout XML instead.

android:autoLink="all"

This should be like this.

<TextView 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:text="@string/txtCredits"
    android:id="@+id/infoTxtCredits"
    android:autoLink="all"
    android:linksClickable="true">
</TextView>

You don't need to use this code (t2.setMovementMethod(LinkMovementMethod.getInstance());) in order to make the link clickable.

Also, here's the truth: as long as you set the autoLink and the linksClickable, don't forget to add this at String.xml file so that the clickable link will work.

<string name="txtCredits"><a href="http://www.google.com">Google</a></string>

Sometimes (for pre-storyboard apps), if the layout is going to be sufficiently different, it's worth specifying a different xib according to device (see this question - you'll need to modify the code to deal with iPhone 5) in the viewController init, as no amount of twiddling with autoresizing masks will work if you need different graphics.

-(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

    NSString *myNibName;
    if ([MyDeviceInfoUtility isiPhone5]) myNibName = @"MyNibIP5";
    else myNibName = @"MyNib";

    if ((self = [super initWithNibName:myNibName bundle:nibBundleOrNil])) {


...

This is useful for apps which are targeting older iOS versions.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.Main_Activity);
    this.setTitle("Title name");
}

Following should do the trick:

BigDecimal d = new BigDecimal(10);
int i = d.intValue();

Use function for multilevel loops - this is good way:

function find_dup () {
    for (;;) {
        for(;;) {
            if (done) return;
        }
    }
}

a = 2
x = 0

Do Until Cells(a, 1).Value = ""
If Rows(a).Hidden = False Then
x = Cells(a, 1).Value + x
End If
a = a + 1
Loop

End Sub

Try writting the lambda with the same conditions as the delegate. like this:

  List<AnalysisObject> analysisObjects = 
    analysisObjectRepository.FindAll().Where(
    (x => 
       (x.ID == packageId)
    || (x.Parent != null && x.Parent.ID == packageId)
    || (x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)
    ).ToList();

With plt.scatter, I can only think of one: to use a proxy artist:

df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), index = pd.date_range('2010-01-01', freq = 'M', periods = 10), columns = ('one', 'two', 'three'))
df['key1'] = (4,4,4,6,6,6,8,8,8,8)
fig1 = plt.figure(1)
ax1 = fig1.add_subplot(111)
x=ax1.scatter(df['one'], df['two'], marker = 'o', c = df['key1'], alpha = 0.8)

ccm=x.get_cmap()
circles=[Line2D(range(1), range(1), color='w', marker='o', markersize=10, markerfacecolor=item) for item in ccm((array([4,6,8])-4.0)/4)]
leg = plt.legend(circles, ['4','6','8'], loc = "center left", bbox_to_anchor = (1, 0.5), numpoints = 1)

And the result is:

Making any Swift class subclass of NSObject makes sense also I prefer for using any Swift class to be seen in Objective-C classes like:

@objc(MySwiftClass)
@objcMembers class MySwiftClass {...}

A no throw specification on an inlined function that only returns a member variable and could not possibly throw exceptions may be used by some compilers to do pessimizations (a made-up word for the opposite of optimizations) that can have a detrimental effect on performance. This is described in the Boost literature: Exception-specification

With some compilers a no-throw specification on non-inline functions may be beneficial if the correct optimizations are made and the use of that function impacts performance in a way that it justifies it.

To me it sounds like whether to use it or not is a call made by a very critical eye as part of a performance optimization effort, perhaps using profiling tools.

A quote from the above link for those in a hurry (contains an example of bad unintended effects of specifying throw on an inline function from a naive compiler):

Exception-specification rationale

Exception specifications [ISO 15.4] are sometimes coded to indicate what exceptions may be thrown, or because the programmer hopes they will improve performance. But consider the following member from a smart pointer:

T& operator*() const throw() { return *ptr; }

This function calls no other functions; it only manipulates fundamental data types like pointers Therefore, no runtime behavior of the exception-specification can ever be invoked. The function is completely exposed to the compiler; indeed it is declared inline Therefore, a smart compiler can easily deduce that the functions are incapable of throwing exceptions, and make the same optimizations it would have made based on the empty exception-specification. A "dumb" compiler, however, may make all kinds of pessimizations.

For example, some compilers turn off inlining if there is an exception-specification. Some compilers add try/catch blocks. Such pessimizations can be a performance disaster which makes the code unusable in practical applications.

Although initially appealing, an exception-specification tends to have consequences that require very careful thought to understand. The biggest problem with exception-specifications is that programmers use them as though they have the effect the programmer would like, instead of the effect they actually have.

A non-inline function is the one place a "throws nothing" exception-specification may have some benefit with some compilers.

1. Place your image in a div.
2. Give your div explicit square dimensions.
3. Set the CSS overflow property on the div to hidden (overflow:hidden).
4. Put your imagine inside the div.
5. Profit.

For example:

<div style="width:200px;height:200px;overflow:hidden">
    <img src="foo.png" />
</div>

Why not download the English Wikipedia? There are compressed SQL files of various sizes, and it should certainly be large enough for you

The main articles are XML, so inserting them into the db is a bit more of a problem, but you might find there are other files there that suit you. For example, the inter-page links SQL file is 2.3GB compressed. Have a look at https://en.wikipedia.org/wiki/Wikipedia:Database_download for more info.

A and B reference the same object, so A.a and B.a reference the same property of the same object.

Edit

Here's a "copy" function that may do the job, it can do both shallow and deep clones. Note the caveats. It copies all enumerable properties of an object (not inherited properties), including those with falsey values (I don't understand why other approaches ignore them), it also doesn't copy non–existent properties of sparse arrays.

There is no general copy or clone function because there are many different ideas on what a copy or clone should do in every case. Most rule out host objects, or anything other than Objects or Arrays. This one also copies primitives. What should happen with functions?

So have a look at the following, it's a slightly different approach to others.

/* Only works for native objects, host objects are not
** included. Copies Objects, Arrays, Functions and primitives.
** Any other type of object (Number, String, etc.) will likely give 
** unexpected results, e.g. copy(new Number(5)) ==> 0 since the value
** is stored in a non-enumerable property.
**
** Expects that objects have a properly set *constructor* property.
