Swift 5 Cant fetch data from your api. Easiest way to parse json is Use Decodable protocol. Or Codable (Encodable & Decodable). For ex:

let json = """
{
    "dueDate": {
        "year": 2021,
        "month": 2,
        "day": 17
    }
}
"""

struct WrapperModel: Codable {
    var dueDate: DueDate
}

struct DueDate: Codable {
    var year: Int
    var month: Int
    var day: Int
}

let jsonData = Data(json.utf8)

let decoder = JSONDecoder()

do {
    let model = try decoder.decode(WrapperModel.self, from: jsonData)
    print(model)
} catch {
    print(error.localizedDescription)
}

Is there a command that does?

Problems with the stack frames could indicate stack corruption (a truely horrible beast), optimisation, or mixing frameworks such as C/C++/C#/Delphi and other craziness as that - there is no absolute standard with respect to stack frames. (Some languages do not even have them!).

So, I suggest getting slightly annoyed with the stack frame issues, ignoring it, and then just use Remy's answer.

The saga continues with the Windows 10 version. I had to install Win Debug Tools on clean Windows 10 OS with Visual Studio 2015.

To make a long story short, just follow the instructions in the link provided by David Black. After downloading the files, instead of running the SDK installer, browse to the installers directory and execute the msi files directly.

I wonder how many man hours have been lost through the last decade because of MS sloppiness in regards to WDK/SDK installation?

Doxygen creates inheritance diagrams but I dont think it will create an entire class hierachy. It does allow you to use the GraphViz tool. If you use the Doxygen GUI frontend tool you will find the relevant options in Step2: -> Wizard tab -> Diagrams. The DOT relation options are under the Expert Tab.

If "key" is your PK field and it's autonumeric.

insert into MyTable (field1, field2, field3, parentkey)
select field1, field2, null, key from MyTable where uniqueId = @Id

it will generate a new record, copying field1 and field2 from the original record

I know this is an old question but I believed the asker wanted the class, not the class name. I wrote a little method that will get the actual class. It is sort of cheaty and may not always work, but sometimes when you need the actual class, you will have to use this method...

/**
     * Get the caller class.
     * @param level The level of the caller class.
     *              For example: If you are calling this class inside a method and you want to get the caller class of that method,
     *                           you would use level 2. If you want the caller of that class, you would use level 3.
     *
     *              Usually level 2 is the one you want.
     * @return The caller class.
     * @throws ClassNotFoundException We failed to find the caller class.
     */
    public static Class getCallerClass(int level) throws ClassNotFoundException {
        StackTraceElement[] stElements = Thread.currentThread().getStackTrace();
        String rawFQN = stElements[level+1].toString().split("\\(")[0];
        return Class.forName(rawFQN.substring(0, rawFQN.lastIndexOf('.')));
    }

I've done something very similar to what 'tvanfosson' said, that is, actually using JavaScript to constantly monitor the available height in the window via events like onresize, and use that information to change the container size accordingly (as pixels rather than percentage).

Keep in mind, this does mean a JavaScript dependency, and it isn't as smooth as a CSS solution. You'd also need to ensure that the JavaScript function is capable of correctly returning the window dimensions across all major browsers.

Let us know if one of the previously mentioned CSS solutions work, as it sounds like a better way to fix the problem.

It is an error on all Samsung devices, the solution is: put this line in your activity declaration in Manifest.

android:configChanges="orientation|screenSize"

also when you start the activity you should do this:

Intent intent = new Intent(CurrentActivity.this, NextActivity.class);
intent.setType(Settings.ACTION_SYNC_SETTINGS);
CurrentActivity.this.startActivity(intent);
finish();

I used this to make an activity as fullscreen mode, but this question does not need the fullscreen code, but in all cases might someone need it you can refer to this question for the rest of the code:

How to make VideoView full screen

As describe here

1. Open your php.ini file (look for it)

2. Add the following line of code on the top of the file:

   date.timezone = "US/Central"

3. Verify the changes by going to phpinfo.php

How about creating your own Custom Panel class? That way you won't have to worry about overriding Bootstrap.

Alternatively here's a simple jQuery solution:

$('#menu-main > li > .dropdown-toggle').click(function () {
    window.location = $(this).attr('href');
});

You can also, and this is my favorite, set a folder as static path so that the files inside are reachable for everyone.

app = Flask(__name__, static_url_path='/static')

With that set you can use the standard HTML:

<link rel="stylesheet" type="text/css" href="/static/style.css">

That's the way it was designed - and it makes sense because usually, you would call bytes on an iterable instead of a single integer:

>>> bytes([3])
b'\x03'

The docs state this, as well as the docstring for bytes:

 >>> help(bytes)
 ...
 bytes(int) -> bytes object of size given by the parameter initialized with null bytes

http://rreddy.blogspot.com/2009/07/vncviewer-clipboard-operations-like.html

Many times you must have observed that clipboard operations like copy/cut and paste suddenly stops workings with the vncviewer. The main reason for this there is a program called as vncconfig responsible for these clipboard transfers. Some times the program may get closed because of some bug in vnc or some other reasons like you closed that window.

To get those clipboard operations back you need to run the program "vncconfig &".

After this your clipboard actions should work fine with out any problems.

Run "vncconfig &" on the client.

I recently migrated my MongoDB to DynamoDB, and wrote 3 blogs to share some experience and data about performance, cost.

Run this from the branch where you want the file to end up:

git checkout otherbranch myfile.txt

General formulas:

git checkout <commit_hash> <relative_path_to_file_or_dir>
git checkout <remote_name>/<branch_name> <file_or_dir>

Some notes (from comments):

• Using the commit hash you can pull files from any commit
• This works for files and directories
• overwrites the file myfile.txt and mydir
• Wildcards don't work, but relative paths do
• Multiple paths can be specified

an alternative:

git show commit_id:path/to/file > path/to/file

can you please try this: replace the case statement with the below one

make interface into custom adapter class and handling click event on recycler view..

 onItemClickListner onItemClickListner;

public void setOnItemClickListner(CommentsAdapter.onItemClickListner onItemClickListner) {
    this.onItemClickListner = onItemClickListner;
}

public interface onItemClickListner {
    void onClick(Contact contact);//pass your object types.
}
    @Override
public void onBindViewHolder(ItemViewHolder holder, int position) {
    // below code handle click event on recycler view item.
    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            onItemClickListner.onClick(mContectList.get(position));
        }
    });
}

after define adapter and bind into recycler view called below code..

        adapter.setOnItemClickListner(new CommentsAdapter.onItemClickListner() {
        @Override
        public void onClick(Contact contact) {
            contectList.remove(contectList.get(contectList.indexOf(contact)));
            adapter.notifyDataSetChanged();
        }

For PHP I would recommend PhpStorm.

It supports FTP/SFTP synchronization, integrates well with Subversion, CVS, Mercurial and even with Git. Also, it supports HTML, CSS, JavaScript and handles language-mixing well like SQL or HTML blocks inside PHP code, JSON, etc.

But if you need Ruby you can try another IDE - RubyMine with same capabilities but for Ruby.

If you're using ZLib in your project, then you need to find :

#if 1

in zconf.h and replace(uncomment) it with :

#if HAVE_UNISTD_H /* ...the rest of the line

If it isn't ZLib I guess you should find some alternative way to do this. GL.

As a practical matter, the advantage of synchronized methods over synchronized blocks is that they are more idiot-resistant; because you can't choose an arbitrary object to lock on, you can't misuse the synchronized method syntax to do stupid things like locking on a string literal or locking on the contents of a mutable field that gets changed out from under the threads.

On the other hand, with synchronized methods you can't protect the lock from getting acquired by any thread that can get a reference to the object.

So using synchronized as a modifier on methods is better at protecting your cow-orkers from hurting themselves, while using synchronized blocks in conjunction with private final lock objects is better at protecting your own code from the cow-orkers.

It might be better to see the standard designed by W3.org. Here is the address: http://www.w3.org/

If you don't want to set a background property then you can't set the src attribute of an image using only CSS.

Alternatively you can use JavaScript to do such a thing.

Download whatever configuration script that your browser is using.

the script would have various host:port configuration. based on the domain you want to connect , one of the host:port is selected by the borwser.

in the eclipse network setting you can try to put on of the host ports and see if that works.

worked for me.

the config script looks like,

if (isPlainHostName(host))
    return "DIRECT";
else if (dnsDomainIs(host, "<***sample host name *******>"))
    return "PROXY ***some ip*****; DIRECT";
else if (dnsDomainIs(host, "address.com")
        || dnsDomainIs(host, "adress2..com")
        || dnsDomainIs(host, "address3.com")
        || dnsDomainIs(host, "address4.com")        
    return "PROXY <***some proxyhost****>:8080";

you would need to look for the host port in the return statement.

Worked for me.

Try to modify the eclipse.ini so that both Xms and Xmx are of the same value:

-Xms6000m
-Xmx6000m

This should force the Eclipse's VM to allocate 6GB of heap right from the beginning.

But be careful about either using the eclipse.ini or the command-line ./eclipse/eclipse -vmargs .... It should work in both cases but pick one and try to stick with it.

This is how the kids are doing it today:

DECLARE @test DECIMAL(18,6) = 123.456789

NullPointerExceptions are among the easier exceptions to diagnose, frequently. Whenever you get an exception in Java and you see the stack trace ( that's what your second quote-block is called, by the way ), you read from top to bottom. Often, you will see exceptions that start in Java library code or in native implementations methods, for diagnosis you can just skip past those until you see a code file that you wrote.

Then you like at the line indicated and look at each of the objects ( instantiated classes ) on that line -- one of them was not created and you tried to use it. You can start by looking up in your code to see if you called the constructor on that object. If you didn't, then that's your problem, you need to instantiate that object by calling new Classname( arguments ). Another frequent cause of NullPointerExceptions is accidentally declaring an object with local scope when there is an instance variable with the same name.

In your case, the exception occurred in your constructor for Workshop on line 75. <init> means the constructor for a class. If you look on that line in your code, you'll see the line

denimjeansButton.addItemListener(this);

There are fairly clearly two objects on this line: denimjeansButton and this. this is synonymous with the class instance you are currently in and you're in the constructor, so it can't be this. denimjeansButton is your culprit. You never instantiated that object. Either remove the reference to the instance variable denimjeansButton or instantiate it.

Ok I have found a solution. The problem is that the site uses SSLv3. And I know that there are some problems in the openssl module. Some time ago I had the same problem with the SSL versions.

<?php
function getSSLPage($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSLVERSION,3); 
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

var_dump(getSSLPage("https://eresearch.fidelity.com/eresearch/evaluate/analystsOpinionsReport.jhtml?symbols=api"));
?>

When you set the SSL Version with curl to v3 then it works.

Edit:

Another problem under Windows is that you don't have access to the certificates. So put the root certificates directly to curl.

http://curl.haxx.se/docs/caextract.html

here you can download the root certificates.

curl_setopt($ch, CURLOPT_CAINFO, __DIR__ . "/certs/cacert.pem");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);

Then you can use the CURLOPT_SSL_VERIFYPEER option with true otherwise you get an error.

Working version of kgaidis's Objective C answer using Swift 3.0:

let flow = UICollectionViewFlowLayout()

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {        
    let numberOfItems = collectionView.numberOfItems(inSection: 0)
    let combinedItemWidth:CGFloat = (CGFloat(numberOfItems) * flow.itemSize.width) + ((CGFloat(numberOfItems) - 1) * flow.minimumInteritemSpacing)
    let padding = (collectionView.frame.size.width - combinedItemWidth) / 2

    return UIEdgeInsetsMake(0, padding, 0, padding)
}

This answer could be really late, but its useful.

You can play youtube videos in the app itself using android-youtube-player.

Some code snippets:

To play a youtube video that has a video id in the url, you simply call the OpenYouTubePlayerActivity intent

Intent intent = new Intent(null, Uri.parse("ytv://"+v), this, 
            OpenYouTubePlayerActivity.class);
startActivity(intent);

where v is the video id.

Add the following permissions in the manifest file:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

and also declare this activity in the manifest file:

<activity 
        android:name="com.keyes.youtube.OpenYouTubePlayerActivity"></activity>

Further information can be obtained from the first portions of this code file.

Hope that helps anyone!

The main problem is that:

in a constructor, the injection of the dependencies has not yet occurred*

_{*obviously excluding Constructor Injection}

Real-world example:

public class Foo {

    @Inject
    Logger LOG;

    @PostConstruct
    public void fooInit(){
        LOG.info("This will be printed; LOG has already been injected");
    }

    public Foo() {
        LOG.info("This will NOT be printed, LOG is still null");
        // NullPointerException will be thrown here
    }
}

IMPORTANT: @PostConstruct and @PreDestroy have been completely removed in Java 11.

To keep using them, you'll need to add the javax.annotation-api JAR to your dependencies.

Maven

<!-- https://mvnrepository.com/artifact/javax.annotation/javax.annotation-api -->
<dependency>
    <groupId>javax.annotation</groupId>
    <artifactId>javax.annotation-api</artifactId>
    <version>1.3.2</version>
</dependency>

Gradle

// https://mvnrepository.com/artifact/javax.annotation/javax.annotation-api
compile group: 'javax.annotation', name: 'javax.annotation-api', version: '1.3.2'

You can use StringEscapeUtils from Apache Commons Logging utility or escape manually using code for each character.

Besides the redundant ) this expression will always be true because currentStatus will always match one of these two conditions:

currentStatus !== 'open' || currentStatus !== 'reopen'

perhaps you mean one of

!(currentStatus === 'open' || currentStatus === 'reopen')
(currentStatus !== 'open' && currentStatus !== 'reopen')

I'd go for regexp_replace, although I'm not 100% sure this is usable in PL/SQL

my_value := regexp_replace(my_value, '[[:space:]]*',''); 

This is relatively new to C# which makes it easy for us to call the functions with respect to the null or non-null values in method chaining.

old way to achieve the same thing was:

var functionCaller = this.member;
if (functionCaller!= null)
    functionCaller.someFunction(var someParam);

and now it has been made much easier with just:

member?.someFunction(var someParam);

I strongly recommend this doc page.

Now, the purpose of CRA is not to worry about these.

From the documentation:

You don’t need to install or configure tools like Webpack or Babel. They are preconfigured and hidden so that you can focus on the code.

If you want to have access to the config files, you need to eject by running:

npm run eject

Note: this is a one-way operation. Once you eject, you can’t go back!

In most scenarios, it is best not to eject and try to find a way to make it work for you in another way.

If you need to override some of the config options, you can have a look at https://github.com/gsoft-inc/craco

I've written a little tool called psql2csv that encapsulates the COPY query TO STDOUT pattern, resulting in proper CSV. It's interface is similar to psql.

psql2csv [OPTIONS] < QUERY
psql2csv [OPTIONS] QUERY

The query is assumed to be the contents of STDIN, if present, or the last argument. All other arguments are forwarded to psql except for these:

-h, --help           show help, then exit
--encoding=ENCODING  use a different encoding than UTF8 (Excel likes LATIN1)
--no-header          do not output a header

In VS 2015 it can be achieved by Team Explorer > Connect > Manage Connections and selecting the team project again. In case of there exist more than one account in VS, Team Explorer asks for which account to use to connect to the team project.

Completely untested, but this should work:

layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
positiveButton.setLayoutParams(layoutParams);

Google Apps Script will not open automatically web pages, but it could be used to display a message with links, buttons that the user could click on them to open the desired web pages or even to use the Window object and methods like addEventListener() to open URLs.

It's worth to note that UiApp is now deprecated. From Class UiApp - Google Apps Script - Google Developers

Deprecated. The UI service was deprecated on December 11, 2014. To create user interfaces, use the HTML service instead.

The example in the HTML Service linked page is pretty simple,

Code.gs

// Use this code for Google Docs, Forms, or new Sheets.
function onOpen() {
  SpreadsheetApp.getUi() // Or DocumentApp or FormApp.
      .createMenu('Dialog')
      .addItem('Open', 'openDialog')
      .addToUi();
}

function openDialog() {
  var html = HtmlService.createHtmlOutputFromFile('index')
      .setSandboxMode(HtmlService.SandboxMode.IFRAME);
  SpreadsheetApp.getUi() // Or DocumentApp or FormApp.
      .showModalDialog(html, 'Dialog title');
}

This works for me if you have config and the private key file in the /Jenkins/.ssh/ you need to chown (change owner) for these 2 files then restart jenkins in order for the jenkins instance to read these 2 files.

Extending the above post by Tom, if you need a class type declaration and access the singleton instance using a variable, the code below might be of help. I like this notation as the code is little self guiding.

function SingletonClass(){
    if ( arguments.callee.instance )
        return arguments.callee.instance;
    arguments.callee.instance = this;
}


SingletonClass.getInstance = function() {
    var singletonClass = new SingletonClass();
    return singletonClass;
};

To access the singleton, you would

var singleTon = SingletonClass.getInstance();

Here is my solution:

public static boolean isPIDInUse(int pid) {

        try {

            String s = null;
            int java_pid;

            RuntimeMXBean rt = ManagementFactory.getRuntimeMXBean();
            java_pid = Integer.parseInt(rt.getName().substring(0, rt.getName().indexOf("@")));

            if (java_pid == pid) {
                System.out.println("In Use\n");
                return true;
            }
        } catch (Exception e) {
            System.out.println("Exception:  " + e.getMessage());
        }
        return false;
    }

If you are using LoaderManager try with this statement:

getLoaderManager().restartLoader(0, null, this);

Boris Smus's article High DPI Images for Variable Pixel Densities has a more accurate definition of device pixel ratio: the number of device pixels per CSS pixel is a good approximation, but not the whole story.

Note that you can get the DPR used by a device with window.devicePixelRatio.

Some years ago, in a safety critical field, I have heard something like one day for unit testing ten lines of code.

There can be one more reason for such behavior - you delete current working directory.

# in terminal #2
rm -rf /home/user/myJavaApp

# in terminal #1
java -jar myJar.jar

You are giving the span a 100% width resulting in it expanding to the size of the parent. This means you can’t center-align it, as there is no room to move it.

You could give the span a set width, then add the margin:0 auto again. This would center-align it.

.left 
{
   background-color: #999999;
   height: 50px;
   width: 24.5%;
}
span.panelTitleTxt 
{
   display:block;
   width:100px;
   height: 100%;
   margin: 0 auto;
}

Use: LOGGER.log(Level.INFO, "Got an exception.", e);
or LOGGER.info("Got an exception. " + e.getMessage());

            }

Clean your data from your tables and then make relation between them.

Best way to rounding off a floating value by "n" decimal places, is as following with in O(1) time:-

We have to round off the value by 3 places i.e. n=3.So,

float a=47.8732355;
printf("%.3f",a);

It is possible, but only if the struct you're initializing is a POD (plain old data) struct. It cannot contain any methods, constructors, or even default values.

If splitting very large files, the solution I found is an adaptation from this, with PowerShell "embedded" in a batch file. This works fast, as opposed to many other things I tried (I wouldn't know about other options posted here).

The way to use mysplit.bat below is

mysplit.bat <mysize> 'myfile'

Note: The script was intended to use the first argument as the split size. It is currently hardcoded at 100Mb. It should not be difficult to fix this.

Note 2: The filname should be enclosed in single quotes. Other alternatives for quoting apparently do not work.

Note 3: It splits the file at given number of bytes, not at given number of lines. For me this was good enough. Some lines of code could be probably added to complete each chunk read, up to the next CR/LF. This will split in full lines (not with a constant number of them), with no sacrifice in processing time.

A simple solution that works well, is to parse the double from the string representation of the float:

double val = Double.valueOf(String.valueOf(yourFloat));

Not super efficient, but it works!

Try this, it's work for me:

<select name="select_name" id="select_id" class="select2_extend_height wrap form-control" data-placeholder="----">
<option value=""></option>
<option value="1">test</option>
</select>

.wrap.select2-selection--single {
    height: 100%;
}
.select2-container .wrap.select2-selection--single .select2-selection__rendered {
    word-wrap: break-word;
    text-overflow: inherit;
    white-space: normal;
}

$('.select2_extend_height').select2({containerCssClass: "wrap"});

Use

[A-Z]?

to make the letter optional. {1} is redundant. (Of course you could also write [A-Z]{0,1} which would mean the same, but that's what the ? is there for.)

You could improve your regex to

^([0-9]{5})+\s+([A-Z]?)\s+([A-Z])([0-9]{3})([0-9]{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])[0-9]{3}([0-9]{4})([0-9]{2})([0-9]{2})

And, since in most regex dialects, \d is the same as [0-9]:

^(\d{5})+\s+([A-Z]?)\s+([A-Z])(\d{3})(\d{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])\d{3}(\d{4})(\d{2})(\d{2})

But: do you really need 11 separate capturing groups? And if so, why don't you capture the fourth-to-last group of digits?

I also experienced that for example:

This code doesnt work and get the intended block error.

class Foo(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
pub_date = models.DateTimeField('date published')
likes = models.IntegerField()

def __unicode__(self):
return self.title

However, when i press tab before typing return self.title statement, the code works.

class Foo(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
pub_date = models.DateTimeField('date published')
likes = models.IntegerField()

def __unicode__(self):
    return self.title

Hope, this will help others.

This issue occured a few days ago with my Bitbucket repositories. I was able to fix it by setting the remote url to http rather than https.

I also tried setting https proxies in the command line and git config but this didn't work.

$ git pull

Note that we are using https:

$ git remote -v
origin  https://[email protected]/sacgf/x.git (fetch)
origin  https://[email protected]/sacgf/x.git (push)

Replace https url with http url:

$ git remote set-url origin http://[email protected]/sacgf/x.git
$ git pull

You are confusing regular expression with shell globbing. If you want to use regular expression to match file names you could do:

$ ls | egrep '.+\..+'

Just check for the current Facebook user id $user and if it returned null then you need to reauthorize the user (or use the custom $_SESSION user id value - not recommended)

require 'facebook/src/facebook.php';


// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
  'appId'  => 'APP_ID',
  'secret' => 'APP_SECRET',
));

$user = $facebook->getUser();

$photo_details = array('message' => 'my place');
$file='photos/my.jpg'; //Example image file
$photo_details['image'] = '@' . realpath($file);

if ($user) {
  try {
    // We have a valid FB session, so we can use 'me'
    $upload_photo = $facebook->api('/me/photos', 'post', $photo_details);
  } catch (FacebookApiException $e) {
    error_log($e);
  }
}


// login or logout url will be needed depending on current user state.
if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
// redirect to Facebook login to get a fresh user access_token
  $loginUrl = $facebook->getLoginUrl();
  header('Location: ' . $loginUrl);
}

I've written a tutorial on how to upload a picture to the user's wall.

Here's a simple example that simply returns the last line without need to sort anything from any column:

"SELECT * FROM TableName ORDER BY rowid DESC LIMIT 1;"       

On Windows:-

Go to File -> Settings.

And open the 'Build,Execution,Deployment'. Then open the

Build Tools -> Gradle

Then uncheck -> Offline work on the right.

Click the OK button.

Then Rebuild the Project.

On Mac OS:-

go to Android Studio -> Preferences, and the rest is the same. OR follow steps given in the image

Since static methods can not be inherited . So no use placing it in the interface. Interface is basically a contract which all its subscribers have to follow . Placing a static method in interface will force the subscribers to implement it . which now becomes contradictory to the fact that static methods can not be inherited .

Other answers don't work in angular 5?

I got an error because DatePipe is not a provider, so it cannot be injected. One solution is to put it as a provider in your app module but my preferred solution was to instantiate it.

Instantiate it where needed:

I looked at DatePipe's source code to see how it got the locale: https://github.com/angular/angular/blob/5.2.5/packages/common/src/pipes/date_pipe.ts#L15-L174

I wanted to use it within a pipe, so my example is within another pipe:

    import { Pipe, PipeTransform, Inject, LOCALE_ID } from '@angular/core';
    import { DatePipe } from '@angular/common';

    @Pipe({
        name: 'when',
    })
    export class WhenPipe implements PipeTransform {
        static today = new Date((new Date).toDateString().split(' ').slice(1).join(' '));
        datePipe: DatePipe;

        constructor(@Inject(LOCALE_ID) private locale: string) {
            this.datePipe = new DatePipe(locale);
        }
        transform(value: string | Date): string {
            if (typeof(value) === 'string')
                value = new Date(value);

            return this.datePipe.transform(value, value < WhenPipe.today ? 'MMM d': 'shortTime')
        }
    }

The key here is importing Inject, and LOCALE_ID from angular's core, and then injecting that so you can give it to the DatePipe to instantiate it properly.

Make DatePipe a provider

In your app module you could also add DatePipe to your providers array like this:

    import { DatePipe } from '@angular/common';

    @NgModule({
        providers: [
            DatePipe
        ]
    })

Now you can just have it injected in your constructor where needed (like in cexbrayat's answer).

Summary:

Either solution worked, I don't know which one angular would consider most "correct" but I chose to instantiate it manually since angular didn't provide datepipe as a provider itself.

You'll want to use the formatting macros from inttypes.h.

See this question: Cross platform format string for variables of type size_t?

"currently yes but i think it might cause problems at peak moments" I can confirm, that I had a problem where I got timeouts because of peak requests. After I set the max pool size, the application ran without any problems. IIS 7.5 / ASP.Net

I'd the same problem while I was developing a simple Java application that listens on a specific TCP. Usually, I had no problem, but when I run some stress test I noticed that some connection broke with error socket write exception.

After Investigation I found a solution that solves my problem. I know this question is quite old, but I prefer to share my solution, someone can find it useful.

The problem was on ServerSocket creation. I read from Javadoc there is a default limit of 50 pending sockets. If you try opening another connection, these will be refused. The solution consist simply in change this default configuration at server side. In the following case, I create a Socket server that listen at TCP port 10_000 and accept max 200 pending sockets.

new Thread(() -> {
      try (ServerSocket serverSocket = new ServerSocket(10_000, 200)) {
        logger.info("Server starts listening on TCP port {}", port);

        while (true) {
          try {
            ClientHandler clientHandler = clientHandlerProvider.getObject(serverSocket.accept(), this);
            executor.execute(clientHandler::start);
          } catch (Exception e) {
            logger.error(e.getMessage());
          }
        }

      } catch (IOException | SecurityException | IllegalArgumentException e) {
        logger.error("Could not open server on TCP port {}. Reason: {}", port, e.getMessage());
      }
    }).start();

From Javadoc of ServerSocket:

The maximum queue length for incoming connection indications (a request to connect) is set to the backlog parameter. If a connection indication arrives when the queue is full, the connection is refused.

Using plain javascript

 var isEmpty = document.getElementById('cartContent').innerHTML === "";

And if you are using jquery it can be done like

 var isEmpty = $("#cartContent").html() === "";

The ist and 2nd answer are good but if anybody is looking for having a script or If you want dynamic i.e (db/username/password in variable) then here:

#!/bin/bash



DB="mydb"
USER="user1"
PASS="pass_bla"

mysql -uroot -prootpassword -e "CREATE DATABASE $DB CHARACTER SET utf8 COLLATE utf8_general_ci";
mysql -uroot -prootpassword -e "CREATE USER $USER@'127.0.0.1' IDENTIFIED BY '$PASS'";
mysql -uroot -prootpassword -e "GRANT SELECT, INSERT, UPDATE ON $DB.* TO '$USER'@'127.0.0.1'";

I wasn't in love with the other solutions out there, so, here's another one. It requires the tag you're resizing the text inside of:

1. Be fixed height

2. Not be so long that it'd overrun the boundaries at 10px - the idea being, you don't want it to shoot below that and resize text to become unreadable. Not an issue in our use case, but if it's possible in yours you'd want to give some thoughts to separately truncating before running this.

It uses a binary search to find the best size so I suspect it outperforms a lot of the other solutions here and elsewhere that just step the font-size down by a pixel over and over. Most browsers today support decimals in font sizes as well, and this script has some benefits there since it will get to within .1px of the best answer, whatever that is, even if it's a relatively long decimal. You could easily change the max - fontSize < .1 to some other value than .1 to get less precision for less CPU usage.

Usage:

$('div.event').fitText();

Code:

(function() {
    function resizeLoop(testTag, checkSize) {
        var fontSize = 10;
        var min = 10;
        var max = 0;
        var exceeded = false;

        for(var i = 0; i < 30; i++) {
            testTag.css('font-size', fontSize);
            if (checkSize(testTag)) {
                max = fontSize;

Besides calling omp_get_num_threads() outside of the parallel region in your case, calling omp_set_num_threads() still doesn't guarantee that the OpenMP runtime will use exactly the specified number of threads. omp_set_num_threads() is used to override the value of the environment variable OMP_NUM_THREADS and they both control the upper limit of the size of the thread team that OpenMP would spawn for all parallel regions (in the case of OMP_NUM_THREADS) or for any consequent parallel region (after a call to omp_set_num_threads()). There is something called dynamic teams that could still pick smaller number of threads if the run-time system deems it more appropriate. You can disable dynamic teams by calling omp_set_dynamic(0) or by setting the environment variable OMP_DYNAMIC to false.

To enforce a given number of threads you should disable dynamic teams and specify the desired number of threads with either omp_set_num_threads():

omp_set_dynamic(0);     // Explicitly disable dynamic teams
omp_set_num_threads(4); // Use 4 threads for all consecutive parallel regions
#pragma omp parallel ...
{
    ... 4 threads used here ...
}

or with the num_threads OpenMP clause:

omp_set_dynamic(0);     // Explicitly disable dynamic teams
// Spawn 4 threads for this parallel region only
#pragma omp parallel ... num_threads(4)
{
    ... 4 threads used here ...
}

You have to use the encoding as latin1 to read this file as there are some special character in this file, use the below code snippet to read the file.

The problem here is the encoding type. When Python can't convert the data to be read, it gives an error.

You can you latin1 or other encoding values.

I say try and test to find the right one for your dataset.

Moving into the world of 3D if you want to check if a 3D point is in a Unit Sphere you end up doing something similar. All that is needed to work in 2D is to use 2D vector operations.

    public static bool Intersects(Vector3 point, Vector3 center, float radius)
    {
        Vector3 displacementToCenter = point - center;

        float radiusSqr = radius * radius;

        bool intersects = displacementToCenter.magnitude < radiusSqr;

        return intersects;
    }

For more bolder: font-weight : 900; Or font-weight : bolder;

It's due to you sending one object, and you're expecting two parameters.

Try this and you'll see:

public class UserDetails
{
   public string username { get; set; }
   public string password { get; set; }
}

public JsonResult Login(UserDetails data)
{
   string error = "";
   //the rest of your code
}

I think the biggest confusion is that xml namespace is pointing to some kind of URL that doesn't have any information. But the truth is that the person who invented below namespace:

xmlns:android="http://schemas.android.com/apk/res/android"

could also call it like that:

xmlns:android="asjkl;fhgaslifujhaslkfjhliuqwhrqwjlrknqwljk.rho;il"

This is just a unique identifier. However it is established that you should put there URL that is unique and can potentially point to the specification of used tags/attributes in that namespace. It's not required tho.

Why it should be unique? Because namespaces purpose is to have them unique so the attribute for example called background from your namespace can be distinguished from the background from another namespace.

Because of that uniqueness you do not need to worry that if you create your custom attribute you gonna have name collision.

If you have already staged files, simply unstage them:

git reset HEAD [file-name-A.ext] [file-name-B.ext]

Then add them bit by bit back in.

The first <img /> is invalid - src is a required attribute. data-src is an attribute than can be leveraged by, say, JavaScript, but has no presentational meaning.

This seems to be a little buggy in Pandas 0.23.4?

If there are np.nan values then this will throw an error as expected:

df['col'] = df['col'].astype(np.int64)

But doesn't change any values from float to int as I would expect if "ignore" is used:

df['col'] = df['col'].astype(np.int64,errors='ignore') 

It worked if I first converted np.nan:

df['col'] = df['col'].fillna(0).astype(np.int64)
df['col'] = df['col'].astype(np.int64)

Now I can't figure out how to get null values back in place of the zeroes since this will convert everything back to float again:

df['col']  = df['col'].replace(0,np.nan)

Add this code in the Module :

Public Sub ClearTextBoxes(frm As Form) 

    For Each Control In frm.Controls
        If TypeOf Control Is TextBox Then
            Control.Text = ""     'Clear all text
        End If       
    Next Control

End Sub

Add this code in the Form window to Call the Sub routine:

Private Sub Command1_Click()
    Call ClearTextBoxes(Me)
End Sub

$unixtime = 1307595105;
echo $time = date("m/d/Y h:i:s A T",$unixtime);

Where

http://php.net/manual/en/function.date.php

This might be more desirable, that is use float instead

SELECT fullName, CAST(totalBal as float) totalBal FROM client_info ORDER BY totalBal DESC

Change the node to and create a file, packages.xsd, in the same folder (and include it in the project) with the following contents:

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
      targetNamespace="urn:packages" xmlns="urn:packages">
  <xs:element name="packages">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="package" maxOccurs="unbounded">
          <xs:complexType>
            <xs:attribute name="id" type="xs:string" use="required" />
            <xs:attribute name="version" type="xs:string" use="required" />

      </xs:sequence>
    </xs:complexType>
  </xs:element>

It's probably slightly more efficient to catch a NullPointerException. The above methods mean that the runtime is checking for null pointers twice.

This works if you want the first element, like my_list.get(0)

>>> my_list = [1,2,3]
>>> next(iter(my_list), 'fail')
1
>>> my_list = []
>>> next(iter(my_list), 'fail')
'fail'

I know it's not exactly what you asked for but it might help others.

In order to start a service in its own process, you must specify the following in the xml declaration.

  android:icon="@drawable/icon"
  android:label="@string/service_name"
  >
</service>

Hope this can work

<img id="dummyimage" src="http://dummyimage.com/450x255/" alt="" />

    $("button#changeSize").click(function() {
        if (flag == 0) {
            $("#dummyimage").attr("src", "http://dummyimage.com/250x155/");
            flag = 1;
        } else if (flag == 1) {
            $("#dummyimage").attr("src", "http://dummyimage.com/450x255/");
            flag = 0;

With your private key and public certificate, you need to create a PKCS12 keystore first, then convert it into a JKS.

# Create PKCS12 keystore from private key and public certificate.
openssl pkcs12 -export -name myservercert -in selfsigned.crt -inkey server.key -out keystore.p12

# Convert PKCS12 keystore into a JKS keystore
keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert

To verify the contents of the JKS, you can use this command:

keytool -list -v -keystore mykeystore.jks

If this was not a self-signed certificate, you would probably want to follow this step with importing the certificate chain leading up to the trusted CA cert.

I had the same issue with CakePHP 2.0.1

I tried using

header( 'HTTP/1.1 400 BAD REQUEST' );

and

$this->header( 'HTTP/1.1 400 BAD REQUEST' );

However, neither of these solved my issue.

I did eventually resolve it by using

$this->header( 'HTTP/1.1 400: BAD REQUEST' );

After that, no errors or warning from php / CakePHP.

*edit: In the last $this->header function call, I put a colon (:) between the 400 and the description text of the error.

If all you are doing is replacing the existing data, then you can do this

std::vector<int> data; // evil global :)

void CopyData(int *newData, size_t count)
{
   data.assign(newData, newData + count);
}

>>> import site; site.getsitepackages()
['/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages']

There may be multiple ways to count the tables of a database. My favorite is this on:

SELECT
    COUNT(*)
FROM
    `information_schema`.`tables`
WHERE
    `table_schema` = 'my_database_name'
;

table.foobar
{
   padding:30px; /* if border is not collapsed */
}

or 

table.foobar
{
   border-spacing:0;
}
table.foobar>tbody
{
   display:table;
   border-spacing:0; /* or other preferred */
   border:30px solid transparent; /* 30px is the "padding" */
}

Works in Firefox, Chrome, IE11, Edge.

Depending on how you're using the list, it may be worth it to use a TreeSet and then use the toArray() method at the end. I had a case where I needed a sorted list, and I found that the TreeSet + toArray() was much faster than adding to an array and merge sorting at the end.

I had the same problem on a rackspeed server after changing the php version in the cpanel. Turned out it also changed the permissions of the folder... I set the permission of the folder to 755 with

chmod 755 folder_name

The bug is probably somewhere else in your code, because it should work fine:

>>> 3 not in [2, 3, 4]
False
>>> 3 not in [4, 5, 6]
True

Or with tuples:

>>> (2, 3) not in [(2, 3), (5, 6), (9, 1)]
False
>>> (2, 3) not in [(2, 7), (7, 3), "hi"]
True

Very simple option in case you have many individual columns to delete in a data table and you want to avoid typing in all column names #careadviced

dt <- dt[, -c(1,4,6,17,83,104)]

This will remove columns based on column number instead.

It's obviously not as efficient because it bypasses data.table advantages but if you're working with less than say 500,000 rows it works fine

This error can also occur when opening a Silverlight project that was built in SL 4, while you have SL 5 installed.

Here is an example error message: The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0\Microsoft.Silverlight.CSharp.targets" was not found.

Note the v4.0.

To resolve, edit the project and find:

<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>

And change it to v5.0.

Then reload project and it will open (unless you do not have SL 5 installed).

If the datepicker is in a row of a grid, try something like

editoptions : {
    dataInit : function (e) {
        $(e).datepicker({
            onSelect : function (ev) {
                // here your code
            }
        });
    }
}

first up on create your jsp file : and write the text field which you want
for ex:

after that create your servlet class:

public class test{

protected void doGet(paramter , paramter){

String name  = request.getparameter("name");
 }

}

Yes, it is 128, except for temp tables, whose names can only be up to 116 character long. It is perfectly explained here.

And the verification can be easily made with the following script contained in the blog post before:

DECLARE @i NVARCHAR(800)
SELECT @i = REPLICATE('A', 116)
SELECT @i = 'CREATE TABLE #'+@i+'(i int)'
PRINT @i
EXEC(@i)

If you use Bootstrap 3, you can use one of it's mixins:

.rotate(degrees);

Example:

.rotate(-90deg);

Short solution for preventing user from using context menu, copy and cut in jQuery:

jQuery(document).bind("cut copy contextmenu",function(e){
    e.preventDefault();
});

Also disabling text selection in CSS might come handy:

.noselect {  
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
     user-select: none;
}

I had similar issues when trying to build amtk and utthpmock with jhbuild.

I needed to install the most recent version of autoconf-archive. Instructions are at https://github.com/autoconf-archive/autoconf-archive/blob/master/README-maint. I did an additional sudo make install at the end.

The last step was to update my ACLOCAL_PATH:

echo 'export ACLOCAL_PATH=$ACLOCAL_PATH:/usr/local/share/aclocal' >> ~/.bashrc

After a source ~/.bashrc, all the macros were finally found and the builds succeeded.

where T : struct

The type argument must be a value type. Any value type except Nullable can be specified. See Using Nullable Types (C# Programming Guide) for more information.

where T : class

The type argument must be a reference type, including any class, interface, delegate, or array type. (See note below.)

where T : new() The type argument must have a public parameterless constructor. When used in conjunction with other constraints, the new() constraint must be specified last.

where T : [base class name]

The type argument must be or derive from the specified base class.

where T : [interface name]

The type argument must be or implement the specified interface. Multiple interface constraints can be specified. The constraining interface can also be generic.

where T : U

The type argument supplied for T must be or derive from the argument supplied for U. This is called a naked type constraint.

Answer 1 - Pass the Vars Array to the __construct() in a class, you could also leave the construct empty and pass the Arrays through your functions instead.

<?php

// Create an Array with all needed Sub Arrays Example: 
// Example Sub Array 1
$content_arrays["modals"]= array();

    }

    // Push Values from in the Array using Public Function
    public function array_push_1(){

        // Values
        $this->push_values_1 = array(1,"2B or not 2B",3,"42",5);

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_1 as $this->values){

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

}

// Start the Class with the Contents Array as a Parameter
$content_arrays = new Array_Pushing_Example_1($content_arrays);

// Push Internal Values to the Arrays
$content_arrays->content_arrays = $content_arrays->array_push_1();

// Push External Values to the Arrays
$external_values = array();
$external_values["values_1"] = array("car","house","bike","glass");
$external_values["values_2"] = array("FOO","foo");
$content_arrays->content_arrays = $content_arrays->array_push_2($external_values);

// The Output
echo "Array Custom Content Results 1";
echo "<br>";

Answer 2 - A simple change however would put it inline with modern standards. Just declare your Arrays in the Class.

<?php

// Create a Class
class Array_Pushing_Example_2 {

    // Public to access outside of class
    public $content_arrays;

    // Needed in the class only
    private $push_value_1;
    private $push_value_2;
    private $push_value_3;
    private $push_value_4;  
    private $values;
    private $external_values;

    // Declare Contents Array and Sub Arrays in __construct
    public function __construct(){

        // Declare them
        $this->content_arrays["modals"] = array();
        $this->content_arrays["js_custom"] = array();

    }

    // Push Values from in the Array using Public Function
    public function array_push_1(){

        // Values
        $this->push_values_1 = array(1,"2B or not 2B",3,"42",5);
        $this->push_values_2 = array("a","b","c");

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_1 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_2 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

    // GET Push Values External to the Class with Public Function
    public function array_push_2($external_values){

        $this->push_values_3 = $external_values["values_1"];
        $this->push_values_4 = $external_values["values_2"];

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_3 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_4 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

}

// Start the Class without the Contents Array as a Parameter
$content_arrays = new Array_Pushing_Example_2();

// Push Internal Values to the Arrays
$content_arrays->content_arrays = $content_arrays->array_push_1();

// Push External Values to the Arrays
$external_values = array();
$external_values["values_1"] = array("car","house","bike","glass");
$external_values["values_2"] = array("FOO","foo");
$content_arrays->content_arrays = $content_arrays->array_push_2($external_values);

// The Output
echo "Array Custom Content Results 1";
echo "<br>";
echo "<br>";

echo "Modals - Count: ".count($content_arrays->content_arrays["modals"]);
echo "<br>";
echo "-------------------";
echo "<br>";

// Get Modals Array Results
foreach($content_arrays->content_arrays["modals"] as $modals){

    echo $modals;
    echo "<br>";

}

echo "<br>";
echo "JS Custom - Count: ".count($content_arrays->content_arrays["js_custom"]);
echo "<br>";
echo "-------------------";
echo "<br>";

// Get JS Custom Array Results
foreach($content_arrays->content_arrays["js_custom"] as $js_custom){

    echo $js_custom;
    echo "<br>";


}

echo "<br>";

?>

Both options output the same information and allow a function to push and retrieve information from an Array and sub Arrays to any place in the code(Given that the data has been pushed first). The second option gives more control over how the data is used and protected. They can be used as is just modify to your needs but if they were used to extend a Controller they could share their values among any of the Classes the Controller is using. Neither method requires the use of a Global(s).

Output:

Array Custom Content Results

Modals - Count: 5

a

b

c

FOO

foo

JS Custom - Count: 9

1

2B or not 2B

3

42

5

car

house

bike

glass

You can use LIKE instead of =. Without any wildcards this will have the same effect.

DECLARE @Village TABLE
        (CastleType TEXT)

INSERT INTO @Village
VALUES
  (
    'foo'
  )

SELECT *
FROM   @Village
WHERE  [CastleType] LIKE 'foo' 

text is deprecated. Changing to varchar(max) will be easier to work with.

Also how large is the data likely to be? If you are going to be doing equality comparisons you will ideally want to index this column. This isn't possible if you declare the column as anything wider than 900 bytes though you can add a computed checksum or hash column that can be used to speed this type of query up.

If you launch your program with -enableassertions (or -ea for short) then this statement

assert cond;

is equivalent to

if (!cond)
    throw new AssertionError();

If you launch your program without this option, the assert statement will have no effect.

For example, assert d >= 0 && d <= s.length();, as posted in your question, is equivalent to

if (!(d >= 0 && d <= s.length()))
    throw new AssertionError();

(If you launched with -enableassertions that is.)

Formally, the Java Language Specification: 14.10. The assert Statement says the following:

14.10. The assert Statement
An assertion is an assert statement containing a boolean expression. An assertion is either enabled or disabled. If the assertion is enabled, execution of the assertion causes evaluation of the boolean expression and an error is reported if the expression evaluates to false. If the assertion is disabled, execution of the assertion has no effect whatsoever.

Where "enabled or disabled" is controlled with the -ea switch and "An error is reported" means that an AssertionError is thrown.

And finally, a lesser known feature of assert:

You can append : "Error message" like this:

assert d != null : "d is null";

to specify what the error message of the thrown AssertionError should be.

This post has been rewritten as an article here.

Note that another approach is to keep with the 4.0 validation behaviour, but to define your own class that derives from RequestValidator and set:

<httpRuntime requestValidationType="YourNamespace.YourValidator" />

(where YourNamespace.YourValidator is well, you should be able to guess...)

This way you keep the advantages of 4.0s behaviour (specifically, that the validation happens earlier in the processing), while also allowing the requests you need to let through, through.

Sure it isn't actual right now but I faced this issue also and my way: Looks like 'save_screenshot' have some troubles with creating files with space in name same time as I added randomization to filenames for escaping override.

Here I got method to clean my filename of whitespaces (How do I replace whitespaces with underscore and vice versa?):

def urlify(self, s):
    # Remove all non-word characters (everything except numbers and letters)
    s = re.sub(r"[^\w\s]", '', s)
    # Replace all runs of whitespace with a single dash
    s = re.sub(r"\s+", '-', s)
    return s

then

driver.save_screenshot('c:\\pytest_screenshots\\%s' % screen_name)

where

def datetime_now(prefix):
    symbols = str(datetime.datetime.now())
    return prefix + "-" + "".join(symbols)

screen_name = self.urlify(datetime_now('screen')) + '.png'

A directive which adds another directive to the same element:

You cannot add methods to an existing type unless the existing type is marked as partial, you can only add methods that appear to be a member of the existing type through extension methods. Since this is the case you cannot add static methods to the type itself since extension methods use instances of that type.

There is nothing stopping you from creating your own static helper method like this:

static class DateTimeHelper
{
    public static DateTime Tomorrow
    {
        get { return DateTime.Now.AddDays(1); }
    }
}

Which you would use like this:

DateTime tomorrow = DateTimeHelper.Tomorrow;

Java Programmer's FAQ Part B Sect 6 suggests:

public static void bytefill(byte[] array, byte value) {
    int len = array.length;
    if (len > 0)
    array[0] = value;
    for (int i = 1; i < len; i += i)
        System.arraycopy( array, 0, array, i,
            ((len - i) < i) ? (len - i) : i);
}

This essentially makes log2(array.length) calls to System.arraycopy which hopefully utilizes an optimized memcpy implementation.

However, is this technique still required on modern Java JITs such as the Oracle/Android JIT?

Hope this helps :-)

if(isset($_POST['submit'])){
    ini_set("post_max_size", "30M");
    ini_set("upload_max_filesize", "30M");
    ini_set("memory_limit", "20000M"); 
    $fileName='product_demo.png';

    if($_FILES['imgproduct']['size'] > 0 && 
            (($_FILES["imgproduct"]["type"] == "image/gif") || 
                ($_FILES["imgproduct"]["type"] == "image/jpeg")|| 
                ($_FILES["imgproduct"]["type"] == "image/pjpeg") || 
                ($_FILES["imgproduct"]["type"] == "image/png") &&
                ($_FILES["imgproduct"]["size"] < 2097152))){

        if ($_FILES["imgproduct"]["error"] > 0){
            echo "Return Code: " . $_FILES["imgproduct"]["error"] . "<br />";
        } else {    
            $rnd=rand(100,999);
            $rnd=$rnd."_";
            $fileName = $rnd.trim($_FILES['imgproduct']['name']);
            $tmpName  = $_FILES['imgproduct']['tmp_name'];
            $fileSize = $_FILES['imgproduct']['size'];
            $fileType = $_FILES['imgproduct']['type'];  
            $target = "upload/";
            echo $target = $target .$rnd. basename( $_FILES['imgproduct']['name']) ; 
            move_uploaded_file($_FILES['imgproduct']['tmp_name'], $target);
        }
    } else {
        echo "Sorry, there was a problem uploading your file.";
    }
}

You should move it:

Directory.Move(source, destination);

I came across this looking for a way to format things better in an email to a co-worker. I ended up discovering that if you copy from Visual Studio Code (FREE) it retains the formatting, highlighting and everything else. This editor works with everything and has modules for every programming language I've ever encountered.

Looks beautiful in the email.

There was a relevant answer from Ask Tom published in April 2016.

If you have sufficient server power, you can do

select /*+ parallel */ count(*) from sometable

If you are just after an approximation, you can do :

select 5 * count(*) from sometable sample block (10);

Also, if there is

1. a column that contains no nulls, but is not defined as NOT NULL, and
2. there is an index on that column

you could try:

select /*+ index_ffs(t) */ count(*) from sometable  t where indexed_col is not null

Same functionality i recently achieved using below function.

I wanted to enable SAVE button on edit.

1. Change event is NOT advisable as it will ONLY be fired if after editing, mouse is clicked somewhere else on the page before clicking SAVE button.
2. Key Press doesnt handle Backspace, Delete and Paste options.
3. Key Up handles everything including tab, Shift key.

Hence i wrote below function combining keypress, keyup (for backspace, delete) and paste event for text fields.

Hope it helps you.

function checkAnyFormFieldEdited() {
    /*
     * If any field is edited,then only it will enable Save button
     */
    $(':text').keypress(function(e) { // text written
        enableSaveBtn();
    });

    $(':text').keyup(function(e) {
        if (e.keyCode == 8 || e.keyCode == 46) { //backspace and delete key
            enableSaveBtn();
        } else { // rest ignore
            e.preventDefault();
        }
    });
    $(':text').bind('paste', function(e) { // text pasted
        enableSaveBtn();
    });

    $('select').change(function(e) { // select element changed
        enableSaveBtn();
    });

    $(':radio').change(function(e) { // radio changed
        enableSaveBtn();
    });

    $(':password').keypress(function(e) { // password written
        enableSaveBtn();
    });
    $(':password').bind('paste', function(e) { // password pasted
        enableSaveBtn();
    });

I've implemented pagination in pure React JS recently. Here is a working demo: http://codepen.io/PiotrBerebecki/pen/pEYPbY

You would of course have to adjust the logic and the way page numbers are displayed so that it meets your requirements.

Full code:

class TodoApp extends React.Component {
  constructor() {
    super();
    this.state = {
      todos: ['a','b','c','d','e','f','g','h','i','j','k'],
      currentPage: 1,
      todosPerPage: 3
    };
    this.handleClick = this.handleClick.bind(this);
  }

  handleClick(event) {
    this.setState({
      currentPage: Number(event.target.id)
    });
  }

  render() {
    const { todos, currentPage, todosPerPage } = this.state;

    // Logic for displaying todos
    const indexOfLastTodo = currentPage * todosPerPage;
    const indexOfFirstTodo = indexOfLastTodo - todosPerPage;
    const currentTodos = todos.slice(indexOfFirstTodo, indexOfLastTodo);

    const renderTodos = currentTodos.map((todo, index) => {
      return <li key={index}>{todo}</li>;
    });

    // Logic for displaying page numbers
    const pageNumbers = [];
    for (let i = 1; i <= Math.ceil(todos.length / todosPerPage); i++) {
      pageNumbers.push(i);
    }

    const renderPageNumbers = pageNumbers.map(number => {
      return (
        <li
          key={number}
          id={number}
          onClick={this.handleClick}
        >
          {number}
        </li>
      );
    });

    return (
      <div>
        <ul>
          {renderTodos}
        </ul>
        <ul id="page-numbers">
          {renderPageNumbers}
        </ul>
      </div>
    );
  }
}


ReactDOM.render(
  <TodoApp />,
  document.getElementById('app')
);

Firstly, in histories_T, you are referencing table T_customer (should be T_customers) and secondly, you are missing the FOREIGN KEY clause that REFERENCES orders; which is not being created (or dropped) with the code you provided.

There may be additional errors as well, and I admit Oracle has never been very good at describing the cause of errors - "Mutating Tables" is a case in point.

Let me know if there additional problems you are missing.

I couldn't find anything built in, which is sad. There is this functionality in CodeRush though.

With Notepad++, this feature comes in built in. Just turn on multi-editing from

Setting > Preferences > Editing > Multi-Editing Settings

But its not as intuitive as MS Word which lets you select two words by double clicking on them (after Ctrl of course).

Although both versions of the specific example are equivalent, as already mentioned in the other answers, there is still one small difference between them. The first version includes an unnecessary implicit barrier, encountered at the end of the "omp for". The other implicit barrier can be found at the end of the parallel region. Adding "nowait" to "omp for" would make the two codes equivalent, at least from an OpenMP perspective. I mention this because an OpenMP compiler could generate slightly different code for the two cases.

Update for 2020: Sticking to the original question of 16x16 versus 32x32 icons: the current recommendation should be to provide a 32x32 icon, skipping 16x16 entirely. All current browsers and devices support 32x32 icons. The icon will routinely be upscaled to as much as 192x192 depending on the environment (assuming there are no larger sizes available or the system didn't recognize them). Upscaling from ultra low resolution has a noticeable effect so better stick to 32x32 as the smallest baseline.

For IE, Microsoft recommends 16x16, 32x32 and 48x48 packed in the favicon.ico file.

For iOS, Apple recommends specific file names and resolutions, at most 180x180 for latest devices running iOS 8.

Android Chrome primarily uses a manifest and also relies on the Apple touch icon.

IE 10 on Windows 8.0 requires PNG pictures and a background color and IE 11 on Windows 8.1 and 10 accepts several PNG pictures declared in a dedicated XML file called browserconfig.xml.

Safari for Mac OS X El Capitan introduces an SVG icon for pinned tabs.

Some other platforms look for PNG files with various resolutions, like the 96x96 picture for Google TV or the 228x228 picture for Opera Coast.

Look at this favicon pictures list for a complete reference.

TLDR: This favicon generator can generate all these files at once. The generator can also be implemented as a WordPress plugin. Full disclosure: I am the author of this site.

In the Table Designer on SQL Server Management Studio you can set the where the auto increment will start. Right-click on the table in Object Explorer and choose Design, then go to the Column Properties for the relevant column:

Here the autoincrement will start at 760

Quit (force quit) all instances of chrome. Otherwise the below command will not work.

Executing this command in terminal will open Chrome regardless of where it is installed.

This does not want to be a "just-use-a-library" answer but just in case you're using Lodash you can use .clamp:

_.clamp(yourInput, lowerBound, upperBound);

So that:

_.clamp(22, -10, 10); // => 10

Here is its implementation, taken from Lodash source:

/**
 * The base implementation of `_.clamp` which doesn't coerce arguments.
 *
 * @private
 * @param {number} number The number to clamp.
 * @param {number} [lower] The lower bound.
 * @param {number} upper The upper bound.
 * @returns {number} Returns the clamped number.
 */
function baseClamp(number, lower, upper) {
  if (number === number) {
    if (upper !== undefined) {
      number = number <= upper ? number : upper;
    }
    if (lower !== undefined) {
      number = number >= lower ? number : lower;
    }
  }
  return number;
}

Also, it's worth noting that Lodash makes single methods available as standalone modules, so in case you need only this method, you can install it without the rest of the library:

npm i --save lodash.clamp

Tackling this task, I'd first find the number of decimal places in x, then round y accordingly. I'd use:

y.toFixed(x.toString().split(".")[1].length);

It should convert x to a string, split it over the decimal point, find the length of the right part, and then y.toFixed(length) should round y based on that length.

You can use the apropos function which is used to find the objects using partial name.

rm(list = apropos("data_"))

In my case I was just missing a register TagPrefix at the top. Somehow the previous dev worked without having this in there?

You have to create two triggers, but you can move the common code into a procedure and have them both call the procedure.

tl;dr

ZonedDateTime.now(                    // Capture current moment as seen in the wall-clock time used by the people of a particular region (a time zone).
    ZoneId.of( "America/Montreal" )   // Specify desired/expected time zone. Or pass `ZoneId.systemDefault` for the JVM’s current default time zone.
)                                     // Returns a `ZonedDateTime` object.
.getMinute()                          // Extract the minute of the hour of the time-of-day from the `ZonedDateTime` object.

ZonedDateTime

To capture the current moment as seen in the wall-clock time used by the people of a particular region (a time zone), use ZonedDateTime.

A time zone is crucial in determining a date. For any given moment, the date varies around the globe by zone. For example, a few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec.

If no time zone is specified, the JVM implicitly applies its current default time zone. That default may change at any moment during runtime(!), so your results may vary. Better to specify your desired/expected time zone explicitly as an argument.

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

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

Call any of the many getters to pull out pieces of the date-time.

int    year        = zdt.getYear() ;
int    monthNumber = zdt.getMonthValue() ;
String monthName   = zdt.getMonth().getDisplayName( TextStyle.FULL , Locale.JAPAN ) ;  // Locale determines human language and cultural norms used in localizing. Note that `Locale` has *nothing* to do with time zone.
int    dayOfMonth  = zdt.getDayOfMonth() ;
String dayOfWeek   = zdt.getDayOfWeek().getDisplayName( TextStyle.FULL , Locale.CANADA_FRENCH ) ; 
int    hour        = zdt.getHour() ;  // Extract the hour from the time-of-day.
int    minute      = zdt.getMinute() ;
int    second      = zdt.getSecond() ;
int    nano        = zdt.getNano() ;

The java.time classes resolve to nanoseconds. Your Question asked for the fraction of a second in milliseconds. Obviously, you can divide by a million to truncate nanoseconds to milliseconds, at the cost of possible data loss. Or use the TimeUnit enum for such conversion.

long millis = TimeUnit.NANOSECONDS.toMillis( zdt.getNano() ) ;

DateTimeFormatter

To produce a String to combine pieces of text, use DateTimeFormatter class. Search Stack Overflow for more info on this.

Instant

Usually best to track moments in UTC. To adjust from a zoned date-time to UTC, extract a Instant.

Instant instant = zdt.toInstant() ;

And go back again.

ZonedDateTime zdt = instant.atZone( ZoneId.of( "Africa/Tunis" ) ) ;

LocalDateTime

A couple of other Answers use the LocalDateTime class. That class in not appropriate to the purpose of tracking actual moments, specific moments on the timeline, as it intentionally lacks any concept of time zone or offset-from-UTC.

So what is LocalDateTime good for? Use LocalDateTime when you intend to apply a date & time to any locality or all localities, rather than one specific locality.

For example, Christmas this year starts at the LocalDateTime.parse( "2018-12-25T00:00:00" ). That value has no meaning until you apply a time zone (a ZoneId) to get a ZonedDateTime. Christmas happens first in Kiribati, then later in New Zealand and far east Asia. Hours later Christmas starts in India. More hour later in Africa & Europe. And still not Xmas in the Americas until several hours later. Christmas starting in any one place should be represented with ZonedDateTime. Christmas everywhere is represented with a LocalDateTime.

About java.time

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

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

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

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The better pattern is to create a standalone BroadcastReceiver. This insures that your app can respond to the broadcast, whether or not the Service is running. In fact, using this pattern may remove the need for a constant-running Service altogether.

Register the BroadcastReceiver in your Manifest, and create a separate class/file for it.

Eg:

<receiver android:name=".FooReceiver" >
    <intent-filter >
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

When the receiver runs, you simply pass an Intent (Bundle) to the Service, and respond to it in onStartCommand().

Eg:

public class FooReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // do your work quickly!
        // then call context.startService();
    }   
}

The safest and most complete way to replace the current local branch with the remote:

git stash
git merge --abort
git rebase --abort
git branch -M yourBranch replaced_yourBranch
git fetch origin yourBranch:yourBranch
git checkout yourBranch

The stash line saves the changes that you have not committed. The branch line moves your branch to a different name, freeing up the original name. The fetch line retrieves the latest copy of the remote. The checkout line recreates the original branch as a tracking branch.

Or as a bash function:

replaceWithRemote() {
    yourBranch=${1:-`git rev-parse --abbrev-ref HEAD`}
    git stash
    git merge --abort
    git rebase --abort
    git branch -M ${yourBranch} replaced_${yourBranch}_`git rev-parse --short HEAD`
    git fetch origin ${yourBranch}:${yourBranch}
    git checkout ${yourBranch}
}

which renames the current branch to something like replaced_master_98d258f.

active directory is the directory service database to store the organizational based data,policy,authentication etc whereas ldap is the protocol used to talk to the directory service database that is ad or adam.

Yes, you can store and view images in Firebase. You can use a filepicker to get the image file. Then you can host the image however you want, I prefer Amazon s3. Once the image is hosted you can display the image using the URL generated for the image.

Hope this helps.

<?php
    $res = mysql_query('SELECT getTreeNodeName(1) AS result');
    if ($res === false) {
        echo mysql_errno().': '.mysql_error();
    }
    while ($obj = mysql_fetch_object($res)) {
        echo $obj->result;
    }

EOF means end of file. It's a sign that the end of a file is reached, and that there will be no data anymore.

Edit:

I stand corrected. In this case it's not an end of file. As mentioned, it is passed when CTRL+d (linux) or CTRL+z (windows) is passed.

Can you place the #ulId in the document prior to the ajax load (with css display: none;), or wrap it in a containing div (with css display: none;), then just load the inner html during ajax page load, that way the scroll event will be linked to the div that is already there prior to the ajax?

Then you can use:

$('#ulId').on('scroll',function(){ console.log('Event Fired'); })

obviously replacing ulId with whatever the actual id of the scrollable div is.

Then set css display: block; on the #ulId (or containing div) upon load?

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

The user owner for me is the admin user and the group is _www and works with permissions set to 775 for dir and for files 664

i wrote my own function to return list of object for populate combo box :

public static String getJSONList(java.util.List<Object> list,String kelas,String name, String label) {
        try {
            Object[] args={};
            Class cl = Class.forName(kelas);
            Method getName = cl.getMethod(name, null);
            Method getLabel = cl.getMethod(label, null);
            String json="[";
            for (int i = 0; i < list.size(); i++) {
            Object o = list.get(i);
            if(i>0){
                json+=",";
            }
            json+="{\"label\":\""+getLabel.invoke(o,args)+"\",\"name\":\""+getName.invoke(o,args)+"\"}";
            //System.out.println("Object = " + i+" -> "+o.getNumber());
            }
            json+="]";
            return json;
        } catch (ClassNotFoundException ex) {
            Logger.getLogger(JSONHelper.class.getName()).log(Level.SEVERE, null, ex);
        } catch (Exception ex) {
            System.out.println("Error in get JSON List");
            ex.printStackTrace();
        }
        return "";
    }

and call it from anywhere like :

String toreturn=JSONHelper.getJSONList(list, "com.bean.Contact", "getContactID", "getNumber");

Destroy the datepicker's instance when you don't want it and create new instance whenever necessary.

I know this is ugly but only this seems to be working...

Check this out

 $("#ddlSearchType").change(function () {
        if ($(this).val() == "Required Date" || $(this).val() == "Submitted Date") {
                $("#txtSearch").datepicker();

         }
          else {
                $("#txtSearch").datepicker("destroy");                    
         }
 });

According to my interpretation of the implementation of unicode-escape and the unicode repr in the CPython 2.6.5 source, yes; the only difference between repr(unicode_string) and unicode_string.encode('unicode-escape') is the inclusion of wrapping quotes and escaping whichever quote was used.

They are both driven by the same function, unicodeescape_string. This function takes a parameter whose sole function is to toggle the addition of the wrapping quotes and escaping of that quote.

session.query().with_entities(SomeModel.col1)

is the same as

session.query(SomeModel.col1)

for alias, we can use .label()

session.query(SomeModel.col1.label('some alias name'))

My answer doesn't contribute anything new, just a concrete example I encountered.

import gtk.gdk

w = gtk.gdk.get_default_root_window()

PyDev showed the error message "Undefined variable from import: get_default_root_window()"

In the python shell you can see that this is a 'built-in' module as mentioned in a answer above:

>>> import gtk.gdk
>>> gtk.gdk
<module 'gtk.gdk' (built-in)>

Now under Window->Preferences->PyDev->Interpreters->Python Interpreter, I selected the tab 'Forced Builtins' and added 'gtk.gdk' to the list.

Now the error message didn't show anymore.

When the DLL was created an import lib is usually automatically created and you should use that linked in to your program along with header files to call it but if not then you can manually call windows functions like LoadLibrary and GetProcAddress to get it working.

If you have SQL Server installed there is also a menu option for finding local SSIS packages.

In the Start menu > All Programs > 'Microsoft Sql Server' there should be a menu option for 'Integration Services' > 'Execute Package Utility' (this is available if SSIS was included in your SQLserver installation).

When you open the Execute Package Utility, type your local sql server name in the 'Server Name' textbox and click on the Package button, you will see your saved package in the popup window. From here you can run your previously saved package

For me a Reference to a WebService is a

SERVICE REFERENCE

.

Anyway it's very easy. As someone said, you just have to change the URL in the web.config file.

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="YourServiceSoap" />
      </basicHttpBinding>
    </bindings>
    <client>
        **** CHANGE THE LINE BELOW TO CHANGE THE URL **** 
        <endpoint address="http://10.10.10.100:8080/services/YourService.asmx"
          binding="basicHttpBinding" bindingConfiguration="YourServiceSoap"
          contract="YourServiceRef.YourServiceSoap" name="YourServiceSoap" />
    </client>

Use below syntax to create schema class from XSD file.

C:\xsd C:\Test\test-Schema.xsd /classes /language:cs /out:C:\Test\

You can achieve this using Slf4j and TestWatcher

private static Logger _log = LoggerFactory.getLogger(SampleTest.class.getName());

@Rule
public TestWatcher watchman = new TestWatcher() {
    @Override
    public void starting(final Description method) {
        _log.info("being run..." + method.getMethodName());
    }
};

found = df[df['Column'].str.contains('Text_to_search')]
print(found.count())

the found.count() will contains number of matches

And if it is 0 then means string was not found in the Column.

Add an element to your page (such as a div) and write to that div.

HTML:

<html>
    <header>
        <title>Page Title</title>
    </header>

    <body>
        <div id="myDiv"></div>
    </body>
</html>

jQuery:

$('#myDiv').text('hello world!');

javascript:

document.getElementById('myDiv').innerHTML = 'hello world!';

Use Pry (GitHub).

Install via:

$ gem install pry
$ pry

Then add:

require 'pry'; binding.pry

into your program.

As of pry 0.12.2 however, there are no navigation commands such as next, break, etc. Some other gems additionally provide this, see for example pry-byedebug.

li{
    display:table;
    margin:0px auto 0px auto;
}

This should work.

If you want a version that raises an error:

"string to search".index("needle") 

If you want a version that returns -1:

"string to search".find("needle") 

This is more efficient than the 'in' syntax

You have to add the row explicitly to the table

table.Rows.Add(row);

It works and there's even a common pattern for your approach: the Adapter pattern. But of course, (1) it does not work for casting java primitives to objects and (2) the class has to be adaptable (usually by implementing a custom interface).

With this pattern you could do something like:

Wolf bigBadWolf = new Wolf();
Sheep sheep = (Sheep) bigBadWolf.getAdapter(Sheep.class);

and the getAdapter method in Wolf class:

public Object getAdapter(Class clazz) {
  if (clazz.equals(Sheep.class)) {
    // return a Sheep implementation
    return getWolfDressedAsSheep(this);
  }

  if (clazz.equals(String.class)) {
    // return a String
    return this.getName();
  }

  return null; // not adaptable
}

For you special idea - that is impossible. You can't use a String value for casting.

Even though call and apply achive the same thing, I think there is atleast one place where you cannot use call but can only use apply. That is when you want to support inheritance and want to call the constructor.

Here is a function allows you to create classes which also supports creating classes by extending other classes.

function makeClass( properties ) {
    var ctor = properties['constructor'] || function(){}
    var Super = properties['extends'];
    var Class = function () {
                 // Here 'call' cannot work, only 'apply' can!!!
                 if(Super)
                    Super.apply(this,arguments);  
                 ctor.apply(this,arguments);
                }
     if(Super){
        Class.prototype = Object.create( Super.prototype );
        Class.prototype.constructor = Class;
     }
     Object.keys(properties).forEach( function(prop) {
           if(prop!=='constructor' && prop!=='extends')
            Class.prototype[prop] = properties[prop];
     });
   return Class; 
}

//Usage
var Car = makeClass({
             constructor: function(name){
                         this.name=name;
                        },
             yourName: function() {
                     return this.name;
                   }
          });
//We have a Car class now
 var carInstance=new Car('Fiat');
carInstance.youName();// ReturnsFiat

var SuperCar = makeClass({
               constructor: function(ignore,power){
                     this.power=power;
                  },
               extends:Car,
               yourPower: function() {
                    return this.power;
                  }
              });
//We have a SuperCar class now, which is subclass of Car
var superCar=new SuperCar('BMW xy',2.6);
superCar.yourName();//Returns BMW xy
superCar.yourPower();// Returns 2.6

You can use this

char name[20];
scanf("%20[^\n]", name);

Or this

void getText(char *message, char *variable, int size){
    printf("\n %s: ", message);
    fgets(variable, sizeof(char) * size, stdin);
    sscanf(variable, "%[^\n]", variable);
}

char name[20];
getText("Your name", name, 20);

On Postgres 9.6(PgAdmin 4) , this can be set up in Preferences->Paths->Binary paths: - set PostgreSQL Binary Path variable to "C:\Program Files\PostgreSQL\9.6\bin" or where you have installed

I was looking for shortest way to draw an 1px line, as whole load of separated CSS is not the fastest or shortest solution.

Up to HTML5, the WAS a shorter way for 1px hr: <hr noshade> but.. The noshade attribute of <hr> is not supported in HTML5. Use CSS instead. (nor other attibutes used before, as size, width, align)...

Now, this one is quite tricky, but works well if most simple 1px hr needed:

Variation 1, BLACK hr: (best solution for black)

<hr style="border-bottom: 0px">

Output: FF, Opera - black / Safari - dark gray

Variation 2, GRAY hr (shortest!):

<hr style="border-top: 0px">

Output: Opera - dark gray / FF - gray / Safari - light gray

<hr style="border: none; border-bottom: 1px solid red;">

Output: Opera / FF / Safari : 1px red.

You can do this by adding a div i.e. centerBlock. And give this property in CSS to center the image or any content. Here is the code:

<div class="container">
    <div class="row">
        <div class="col-sm-4 col-md-4 col-lg-4">
            <div class="centerBlock">
                <img class="img-responsive" src="img/some-image.png" title="This image needs to be centered">
            </div>
        </div>
        <div class="col-sm-8 col-md-8 col-lg-8">
            Some content not important at this moment
        </div>
    </div>
</div>


// CSS

.centerBlock {
  display: table;
  margin: auto;
}

The absolutely best way is neither of the 2, but the 3rd. The first parameter to encode defaults to 'utf-8' ever since Python 3.0. Thus the best way is

b = mystring.encode()

This will also be faster, because the default argument results not in the string "utf-8" in the C code, but NULL, which is much faster to check!

Here be some timings:

In [1]: %timeit -r 10 'abc'.encode('utf-8')
The slowest run took 38.07 times longer than the fastest. 
This could mean that an intermediate result is being cached.
10000000 loops, best of 10: 183 ns per loop

In [2]: %timeit -r 10 'abc'.encode()
The slowest run took 27.34 times longer than the fastest. 
This could mean that an intermediate result is being cached.
10000000 loops, best of 10: 137 ns per loop

Despite the warning the times were very stable after repeated runs - the deviation was just ~2 per cent.

Using encode() without an argument is not Python 2 compatible, as in Python 2 the default character encoding is ASCII.

>>> 'äöä'.encode()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

   <form method="post" action="">
   <table>
   <tr><td><input name="Submit" type="submit" value="refresh"></td></tr>
   </table>
   </form>

<?php
    if(isset($_POST['Submit']))
    {
    header("Location: http://yourpagehere.com");
    }
?>

With this one line you can disable any input field in a form

$('form *').prop('disabled', true);

1. Where does user.id go after passport.serializeUser has been called?

The user id (you provide as the second argument of the done function) is saved in the session and is later used to retrieve the whole object via the deserializeUser function.

serializeUser determines which data of the user object should be stored in the session. The result of the serializeUser method is attached to the session as req.session.passport.user = {}. Here for instance, it would be (as we provide the user id as the key) req.session.passport.user = {id: 'xyz'}

2. We are calling passport.deserializeUser right after it where does it fit in the workflow?

The first argument of deserializeUser corresponds to the key of the user object that was given to the done function (see 1.). So your whole object is retrieved with help of that key. That key here is the user id (key can be any key of the user object i.e. name,email etc). In deserializeUser that key is matched with the in memory array / database or any data resource.

The fetched object is attached to the request object as req.user

Visual Flow

passport.serializeUser(function(user, done) {
    done(null, user.id);
});              ¦
                 ¦ 
                 ¦
                 +--------------------? saved to session
                                   ¦    req.session.passport.user = {id: '..'}
                                   ¦
                                   ?           
passport.deserializeUser(function(id, done) {
                   +---------------+
                   ¦
                   ? 
    User.findById(id, function(err, user) {
        done(err, user);
    });            +--------------? user object attaches to the request as req.user   
});

The most efficient way is to take input make the logic and run

so the code is like this to make your own space maker

need = input("Write a string:- ")
result = ''
for character in need:
   result = result + character + ' '
print(result)    # to rid of space after O

but if you want to use what python give then use this code

need2 = input("Write a string:- ")

print(" ".join(need2))

Data List is a new HTML tag in HTML5 supported browsers. It renders as a text box with some list of options. For Example for Gender Text box it will give you options as Male Female when you type 'M' or 'F' in Text Box.

<input list="Gender">
<datalist id="Gender">
  <option value="Male">
  <option value="Female> 
</datalist>

I was getting e.data.indexOf is not a function error, after debugging it, I found that it was actually a TypeError, which meant, indexOf() being a function is applicable to strings, so I typecasted the data like the following and then used the indexOf() method to make it work

e.data.toString().indexOf('<stringToBeMatchedToPosition>')

Not sure if my answer was accurate to the question, but yes shared my opinion as i faced a similar kind of situation.

You need to remove the object from your data array before you call deleteRowsAtIndexPaths:withRowAnimation:. So, your code should look like this:

// Editing of rows is enabled
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {

        //when delete is tapped
        [currentCart removeObjectAtIndex:indexPath.row];

        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }
}

You can also simplify your code a little by using the array creation shortcut @[]:

[tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];

After reading the answers to the question I think encapsulating or wrapping the parseInt method is not necessary, maybe even not a good idea.

You could return 'null' as Jon suggested, but that's more or less replacing a try/catch construct by a null-check. There's just a slight difference on the behaviour if you 'forget' error handling: if you don't catch the exception, there's no assignment and the left hand side variable keeps it old value. If you don't test for null, you'll probably get hit by the JVM (NPE).

yawn's suggestion looks more elegant to me, because I do not like returning null to signal some errors or exceptional states. Now you have to check referential equality with a predefined object, that indicates a problem. But, as others argue, if again you 'forget' to check and a String is unparsable, the program continous with the wrapped int inside your 'ERROR' or 'NULL' object.

Nikolay's solution is even more object orientated and will work with parseXXX methods from other wrapper classes aswell. But in the end, he just replaced the NumberFormatException by an OperationNotSupported exception - again you need a try/catch to handle unparsable inputs.

So, its my conclusion to not encapsulate the plain parseInt method. I'd only encapsulate if I could add some (application depended) error handling as well.

Angular comes with a limitTo:limit filter, it support limiting first x items and last x items:

<div ng-repeat="item in items|limitTo:4">{{item}}</div>

Please follow the below steps :

 1) Locate php.ini in your apache bin folder, I.e Apache/bin/php.ini
 2) Remove the ; from the beginning of extension=php_soap.dll
 3) Restart your Apache server (by using : 
    # /etc/init.d/apache2 restart OR 
    $ sudo /etc/init.d/apache2 restart OR 
    $ sudo service apache2 restart)
 4) Look up your phpinfo();

There are three reasons why you shouldn't use for..in to iterate over array elements:

• for..in will loop over all own and inherited properties of the array object which aren't DontEnum; that means if someone adds properties to the specific array object (there are valid reasons for this - I've done so myself) or changed Array.prototype (which is considered bad practice in code which is supposed to work well with other scripts), these properties will be iterated over as well; inherited properties can be excluded by checking hasOwnProperty(), but that won't help you with properties set in the array object itself

• for..in isn't guaranteed to preserve element ordering

• it's slow because you have to walk all properties of the array object and its whole prototype chain and will still only get the property's name, ie to get the value, an additional lookup will be required

You can specify the style of the plotted line when calling df.plot:

df.plot(x='col_name_1', y='col_name_2', style='o')

The style argument can also be a dict or list, e.g.:

import numpy as np
import pandas as pd

d = {'one' : np.random.rand(10),
     'two' : np.random.rand(10)}

df = pd.DataFrame(d)

df.plot(style=['o','rx'])

All the accepted style formats are listed in the documentation of matplotlib.pyplot.plot.

In case you don't have access to functools.partial, you could use a wrapper function for this, as well.

def target(lock):
    def wrapped_func(items):
        for item in items:
            # Do cool stuff
            if (... some condition here ...):
                lock.acquire()
                # Write to stdout or logfile, etc.
                lock.release()
    return wrapped_func

def main():
    iterable = [1, 2, 3, 4, 5]
    pool = multiprocessing.Pool()
    lck = multiprocessing.Lock()
    pool.map(target(lck), iterable)
    pool.close()
    pool.join()

This makes target() into a function that accepts a lock (or whatever parameters you want to give), and it will return a function that only takes in an iterable as input, but can still use all your other parameters. That's what is ultimately passed in to pool.map(), which then should execute with no problems.

You can use recursion here to do this. For example:

jQuery(document).ready(checkContainer);

function checkContainer () {
  if($('#divIDer').is(':visible'))){ //if the container is visible on the page
    createGrid();  //Adds a grid to the html
  } else {
    setTimeout(checkContainer, 50); //wait 50 ms, then try again
  }
}

Basically, this function will check to make sure that the element exists and is visible. If it is, it will run your createGrid() function. If not, it will wait 50ms and try again.

Note:: Ideally, you would just use the callback function of your AJAX call to know when the container was appended, but this is a brute force, standalone approach. :)

Here, if you are converting string into byte[].There is a utility code :

    String[] str = result.replaceAll("\\[", "").replaceAll("\\]","").split(", ");
    byte[] dataCopy = new byte[str.length] ;
    int i=0;
    for(String s:str ) {
        dataCopy[i]=Byte.valueOf(s);
        i++;
    }
    return dataCopy;

The direct methods and .delegate are superior APIs to .on and there is no intention of deprecating them.

The direct methods are preferable because your code will be less stringly typed. You will get immediate error when you mistype an event name rather than a silent bug. In my opinion, it's also easier to write and read click than on("click"

The .delegate is superior to .on because of the argument's order:

$(elem).delegate( ".selector", {
    click: function() {
    },
    mousemove: function() {
    },
    mouseup: function() {
    },
    mousedown: function() {
    }
});

You know right away it's delegated because, well, it says delegate. You also instantly see the selector.

With .on it's not immediately clear if it's even delegated and you have to look at the end for the selector:

$(elem).on({
    click: function() {
    },
    mousemove: function() {
    },
    mouseup: function() {
    },
    mousedown: function() {
    }
}, "selector" );

Now, the naming of .bind is really terrible and is at face value worse than .on. But .delegate cannot do non-delegated events and there are events that don't have a direct method, so in a rare case like this it could be used but only because you want to make a clean separation between delegated and non-delegated events.

You need to use the fn:contains() or fn:containsIgnoreCase() function.

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>

...

 <c:if test="${not fn:containsIgnoreCase(mylist, 'apple')}">
        <p>Doesn't contain 'apple'</p>
    </c:if>

or

<c:if test="${not fn:contains(mylist, 'Apple')}">
            <p>Contains 'Apple'</p>
        </c:if>

Note: This will work like mylist.toString().contains("apple") and if this is not what you are looking for better use a other approach.

<div ng-click="methodName(event)"></div>

IN controller use

$scope.methodName = function(event) { 
    event.stopPropagation();
}

Converting it to integer worked for me:

int(sub_df.iloc[0])

inspired by Sammys answer above:

margins = {  #     vvv margin in inches
    "left"   :     1.5 / figsize[0],
    "bottom" :     0.8 / figsize[1],
    "right"  : 1 - 0.3 / figsize[0],
    "top"    : 1 - 1   / figsize[1]
}
fig.subplots_adjust(**margins)

Where figsize is the tuple that you used in fig = pyplot.figure(figsize=...)

insert image zh

-while we insert image in database using insert query

$Image = $_FILES['Image']['name'];
    if(!$Image)
    {
      $Image="";
    }
    else
    {
      $file_path = 'upload/';
      $file_path = $file_path . basename( $_FILES['Image']['name']);    
      if(move_uploaded_file($_FILES['Image']['tmp_name'], $file_path)) 
     { 
}
}

Steps to convert .py to .exe in Python 3.6

1. Install Python 3.6.
2. Install cx_Freeze, (open your command prompt and type pip install cx_Freeze.
3. Install idna, (open your command prompt and type pip install idna.
4. Write a .py program named myfirstprog.py.
5. Create a new python file named setup.py on the current directory of your script.
6. In the setup.py file, copy the code below and save it.
7. With shift pressed right click on the same directory, so you are able to open a command prompt window.
8. In the prompt, type python setup.py build
9. If your script is error free, then there will be no problem on creating application.
10. Check the newly created folder build. It has another folder in it. Within that folder you can find your application. Run it. Make yourself happy.

See the original script in my blog.

setup.py:

from cx_Freeze import setup, Executable

base = None    

executables = [Executable("myfirstprog.py", base=base)]

packages = ["idna"]
options = {
    'build_exe': {    
        'packages':packages,
    },    
}

setup(
    name = "<any name>",
    options = options,
    version = "<any number>",
    description = '<any description>',
    executables = executables
)

EDIT:

• be sure that instead of myfirstprog.py you should put your .pyextension file name as created in step 4;
• you should include each imported package in your .py into packages list (ex: packages = ["idna", "os","sys"])
• any name, any number, any description in setup.py file should not remain the same, you should change it accordingly (ex:name = "<first_ever>", version = "0.11", description = '' )
• the imported packages must be installed before you start step 8.

You can store favourites with no associated menu in a separate table:

CREATE TABLE FavoriteWithoutMenu
(
  FavoriteWithoutMenuId uuid NOT NULL, --Primary key
  UserId uuid NOT NULL,
  RecipeId uuid NOT NULL,
  UNIQUE KEY (UserId, RecipeId)
)
