Programs & Examples On #Barcode

this is my working example Java code to encode QR code using ZXing with UTF-8 encoding, please note: you will need to change the path and utf8 data to your path and language characters

package com.mypackage.qr;

import java.io.File;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.nio.ByteBuffer;
import java.nio.CharBuffer;
import java.nio.charset.CharacterCodingException;

import java.util.Hashtable;

import com.google.zxing.EncodeHintType;
import com.google.zxing.MultiFormatWriter;
import com.google.zxing.client.j2se.MatrixToImageWriter;
import com.google.zxing.common.*;

public class CreateQR {

public static void main(String[] args)
{
    Charset charset = Charset.forName("UTF-8");
    CharsetEncoder encoder = charset.newEncoder();
    byte[] b = null;
    try {
        // Convert a string to UTF-8 bytes in a ByteBuffer
        ByteBuffer bbuf = encoder.encode(CharBuffer.wrap("utf 8 characters - i used hebrew, but you should write some of your own language characters"));
        b = bbuf.array();
    } catch (CharacterCodingException e) {
        System.out.println(e.getMessage());
    }

    String data;
    try {
        data = new String(b, "UTF-8");
        // get a byte matrix for the data
        BitMatrix matrix = null;
        int h = 100;
        int w = 100;
        com.google.zxing.Writer writer = new MultiFormatWriter();
        try {
            Hashtable<EncodeHintType, String> hints = new Hashtable<EncodeHintType, String>(2);
            hints.put(EncodeHintType.CHARACTER_SET, "UTF-8");
            matrix = writer.encode(data,
            com.google.zxing.BarcodeFormat.QR_CODE, w, h, hints);
        } catch (com.google.zxing.WriterException e) {
            System.out.println(e.getMessage());
        }

        // change this path to match yours (this is my mac home folder, you can use: c:\\qr_png.png if you are on windows)
                String filePath = "/Users/shaybc/Desktop/OutlookQR/qr_png.png";
        File file = new File(filePath);
        try {
            MatrixToImageWriter.writeToFile(matrix, "PNG", file);
            System.out.println("printing to " + file.getAbsolutePath());
        } catch (IOException e) {
            System.out.println(e.getMessage());
        }
    } catch (UnsupportedEncodingException e) {
        System.out.println(e.getMessage());
    }
}

}

There is a library for this BarCode PHP. You just need to include a few files:

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

You can generate many types of barcodes, namely 1D or 2D. Add the required library:

require_once('class/BCGcode39.barcode.php');

Generate the colours:

// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);

After you have added all the codes, you will get this way:

Example

Since several have asked for an example here is what I was able to do to get it done

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

require_once('class/BCGcode128.barcode.php');

header('Content-Type: image/png');

$color_white = new BCGColor(255, 255, 255);

$code = new BCGcode128();
$code->parse('HELLO');

$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);

$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);

If you want to actually create the image file so you can save it then change

$drawing = new BCGDrawing('', $color_white);

to

$drawing = new BCGDrawing('image.png', $color_white);

The

compile 'com.google.zxing:core:2.3.0'

unfortunately didn't work for me.

This is what worked for me:

dependencies {
   compile 'com.journeyapps:zxing-android-embedded:3.0.1@aar'
   compile 'com.google.zxing:core:3.2.0'
}

Could the Barcode Rendering Framework at Codeplex GitHub be of help?

2016 update

With the latest release of Google Play Services, v7.8, you have access to the new Mobile Vision API. That's probably the most convenient way to implement barcode scanning now, and it also works offline.

From the Android Barcode API:

The Barcode API detects barcodes in real-time, on device, in any orientation. It can also detect multiple barcodes at once.

It reads the following barcode formats:

• 1D barcodes: EAN-13, EAN-8, UPC-A, UPC-E, Code-39, Code-93, Code-128, ITF, Codabar
• 2D barcodes: QR Code, Data Matrix, PDF-417, AZTEC

It automatically parses QR Codes, Data Matrix, PDF-417, and Aztec values, for the following supported formats:

• URL
• Contact information (VCARD, etc.)
• Calendar event
• Email
• Phone
• SMS
• ISBN
• WiFi
• Geo-location (latitude and longitude)
• AAMVA driver license/ID

Check out ZBar reads QR Code and ECN/ISBN codes and is available as under the LGPL v2 license.

I tried to "Maven > Reimport" but the only thing that actually fixed it was to close the project, delete the .idea directory, and reopen the project.

ZXing is a free open source Java library to read and generate barcode images. You need to get the source code and build the jars yourself. Here's a simple tutorial that I wrote for building with ZXing jars and writing your first program with ZXing.

[http://www.vineetmanohar.com/2010/09/java-barcode-api/]

You can use this quick start guide http://shyyko.wordpress.com/2013/07/30/zxing-with-android-quick-start/ with simple example project to build android app without IntentIntegrator.

For those who are still getting the error even though you added proper keys into Info.plist:

Make sure you are adding the key into correct Info.plist. Newer version of xCode, apparently has 3 Info.plist.

One is under folder with your app's name which solved problem for me.

Second is under YourappnameTests and third one is under YourappnameUITests.

Hope it helps.

you could write

select DISTINCT f from t;

as

select f from t group by f;

thing is, I am just currently myself getting into Doctrine, so I cannot give you a real answer. but you could as shown above, simulate a distinct with group by and transform that into Doctrine. if you want add further filtering then use HAVING after group by.

Use grep and regular expressions, for example if you want 4 minutes interval of logs:

grep "31/Mar/2002:19:3[1-5]" logfile

will return all logs lines between 19:31 and 19:35 on 31/Mar/2002. Supposing you need the last 5 days starting from today 27/Sep/2011 you may use the following:

grep "2[3-7]/Sep/2011" logfile

This worked for me best:

$('.alert').on('close.bs.alert', function (e) {
    e.preventDefault();
    $(this).hide();
});

i know this question is old, but hopefully it will help someone. i found a great plugin for those who are using PyCharm IDE: string-manipulation that can easily escape double quotes (and many more...), this plugin is great for cases where you know what the string going to be. for other cases, using json.dumps(string) will be the recommended solution

str_to_escape = 'my string with "double quotes" blablabla'

after_escape = 'my string with \"double quotes\" blablabla'

Put your image in a container div then use the following CSS (changing the dimensions to suit your image.

.imageContainer{
        position: absolute;
        width: 100px; /*the image width*/
        height: 100px; /*the image height*/
        left: 50%;
        top: 50%;
        margin-left: -50px; /*half the image width*/
        margin-top: -50px; /*half the image height*/
    }

$('#_SelectID').change(function () {
        var SelectedText = $('option:selected',this).text();
        var SelectedValue = $('option:selected',this).val();
});

I've got a similar problem I'm currently working on solving. I can't say this will solve your error since there may be issues with other software (which is my case with Eclipse Luna).

Java is using the path given in your PATH variable, which is,

  C:\ProgramData\Oracle\Java\javapath

Go to this folder (ProgramData is hidden, so unhide it if necessary) and right click on the java.exe symlink. You'll see in the Target field where it's looking for java.exe. It may be pointing to the java.exe file from your previous jdk1.6.0_45 install. Either paste in new shortcuts here or change the PATH setting as others have mentioned.

I've found that the Java installer doesn't change the javapath or update the system path, at least when going from 1.8 to 1.7. In my case changing the shortcuts only led to a problem with Eclipse on startup.

EDIT:----- After playing with javapath folder shortcuts it turns out you need symlinks, at least for Eclipse. See, Windows how to create directory symlink.

You don't need the /d switch for a file symlink,

  mklink java.exe "C:\Program Files\Java\jdk1.8.0_20\bin\java.exe"
  mklink javaw.exe "C:\Program Files\Java\jdk1.8.0_20\bin\javaw.exe"
  mklink javaws.exe "C:\Program Files\Java\jdk1.8.0_20\bin\javaws.exe"

This now works for me.

try this

var configuration = WebConfigurationManager.OpenWebConfiguration("~");
var section = (ConnectionStringsSection)configuration.GetSection("connectionStrings");
section.ConnectionStrings["MyConnectionString"].ConnectionString = "Data Source=...";
configuration.Save();

Mutex and Semaphore didn't work in my case (I tried them as suggested, but it didn't do the trick in the application I developed). The answer abramlimpin provided worked for me, after I made a slight modification.

This is how I got it working finally. First, I created some helper functions:

public static class Ext
{
   private static string AssemblyFileName(this Assembly myAssembly)
    {
        string strLoc = myAssembly.Location;
        FileSystemInfo fileInfo = new FileInfo(strLoc);
        string sExeName = fileInfo.Name;
        return sExeName;
    }

    private static int HowManyTimesIsProcessRunning(string name)
    {
        int count = 0;
        name = name.ToLowerInvariant().Trim().Replace(".exe", "");
        foreach (Process clsProcess in Process.GetProcesses())
        {
            var processName = clsProcess.ProcessName.ToLowerInvariant().Trim();
            // System.Diagnostics.Debug.WriteLine(processName);
            if (processName.Contains(name))
            {
                count++;
            };
        };
        return count;
    }

    public static int HowManyTimesIsAssemblyRunning(this Assembly myAssembly)
    {
        var fileName = AssemblyFileName(myAssembly);
        return HowManyTimesIsProcessRunning(fileName);
    }
}

Then, I added the following to the main method:

[STAThread]
static void Main()
{
    const string appName = "Name of your app";

    // Check number of instances running:
    // If more than 1 instance, cancel this one.
    // Additionally, if it is the 2nd invocation, show a message and exit.
    var numberOfAppInstances = Assembly.GetExecutingAssembly().HowManyTimesIsAssemblyRunning();
    if (numberOfAppInstances == 2)
    {
       MessageBox.Show("The application is already running!
        +"\nClick OK to close this dialog, then switch to the application by using WIN + TAB keys.",
        appName, MessageBoxButtons.OK, MessageBoxIcon.Warning);
    };
    if (numberOfAppInstances >= 2)
    {
        return;
    };
}

If you invoke the application a 3rd, 4th ... time, it does not show the warning any more and just exits immediately.

I was able to get jsPDF to print dynamically created tables from a div.

$(document).ready(function() {

        $("#pdfDiv").click(function() {

    var pdf = new jsPDF('p','pt','letter');
    var specialElementHandlers = {
    '#rentalListCan': function (element, renderer) {
        return true;
        }
    };

    pdf.addHTML($('#rentalListCan').first(), function() {
        pdf.save("caravan.pdf");
    });
    });
});

Works great with Chrome and Firefox... formatting is all blown up in IE.

I also included these:

<script src="js/jspdf.js"></script>
    <script src="js/jspdf.plugin.from_html.js"></script>
    <script src="js/jspdf.plugin.addhtml.js"></script>
    <script src="//mrrio.github.io/jsPDF/dist/jspdf.debug.js"></script>
    <script src="http://html2canvas.hertzen.com/build/html2canvas.js"></script>
    <script type="text/javascript" src="./libs/FileSaver.js/FileSaver.js"></script>
    <script type="text/javascript" src="./libs/Blob.js/Blob.js"></script>
    <script type="text/javascript" src="./libs/deflate.js"></script>
    <script type="text/javascript" src="./libs/adler32cs.js/adler32cs.js"></script>

    <script type="text/javascript" src="js/jspdf.plugin.addimage.js"></script>

    <script type="text/javascript" src="js/jspdf.plugin.split_text_to_size.js"></script>
    <script type="text/javascript" src="js/jspdf.plugin.standard_fonts_metrics.js"></script>

I just add this line exactly as it appears below (if you need a second delay):

try {
    Thread.sleep(1000);
} catch(InterruptedException e) {
    // Process exception
}

I find the catch IS necessary (Your app can crash due to Android OS as much as your own code).

Returning an empty collection is better in most cases.

The reason for that is convenience of implementation of the caller, consistent contract, and easier implementation.

If a method returns null to indicate empty result, the caller must implement a null checking adapter in addition to enumeration. This code is then duplicated in various callers, so why not to put this adapter inside the method so it could be reused.

A valid usage of null for IEnumerable might be an indication of absent result, or an operation failure, but in this case other techniques should be considered, such as throwing an exception.

Step 2 - Test working

import MySQLdb
db = MySQLdb.connect("localhost","myusername","mypassword","mydb" )
cursor = db.cursor()
cursor.execute("SELECT VERSION()")
data = cursor.fetchone()    
print "Database version : %s " % data    
db.close()

Ouput:

Database version : 5.5.20 

This error occurs because of BGSAVE being failed. During BGSAVE, Redis forks a child process to save the data on disk. Although exact reason for failure of BGSAVE can be checked from logs (usually at /var/log/redis/redis-server.log on linux machines) but a lot of the times BGAVE fails because the fork can't allocate memory. Many times the fork fails to allocate memory (although the machine has enough RAM available) because of a conflicting optimization by the OS.

As can be read from Redis FAQ:

Redis background saving schema relies on the copy-on-write semantic of fork in modern operating systems: Redis forks (creates a child process) that is an exact copy of the parent. The child process dumps the DB on disk and finally exits. In theory the child should use as much memory as the parent being a copy, but actually thanks to the copy-on-write semantic implemented by most modern operating systems the parent and child process will share the common memory pages. A page will be duplicated only when it changes in the child or in the parent. Since in theory all the pages may change while the child process is saving, Linux can't tell in advance how much memory the child will take, so if the overcommit_memory setting is set to zero fork will fail unless there is as much free RAM as required to really duplicate all the parent memory pages, with the result that if you have a Redis dataset of 3 GB and just 2 GB of free memory it will fail.

Setting overcommit_memory to 1 says Linux to relax and perform the fork in a more optimistic allocation fashion, and this is indeed what you want for Redis.

Redis doesn't need as much memory as the OS thinks it does to write to disk, so may pre-emptively fail the fork.

To Resolve this, you can:

Modify /etc/sysctl.conf and add:

vm.overcommit_memory=1

Then restart sysctl with:

On FreeBSD:

sudo /etc/rc.d/sysctl reload

On Linux:

sudo sysctl -p /etc/sysctl.conf

input[type="text"]{
   @include transition(all 0.30s ease-in-out);
  outline: none;
  padding: 3px 0px 3px 3px;
  margin: 5px 1px 3px 0px;
  border: 1px solid #DDDDDD;
}
input[type="text"]:focus{
  @include box-shadow(0 0 5px rgba(81, 203, 238, 1));
  -webkit-box-shadow: 0px 0px 5px #007eff;  
  -moz-box-shadow: 0px 0px 5px #007eff;  
  box-shadow: 0px 0px 5px #007eff;
}

Just to add an additional function should you need it. You can include a variable in the named location, for example a date identifier

date <- yyyymmdd
save(city, file=paste0("c:\\myuser\\somelocation\\",date,"_RData.Data")

This was you can always keep a check of when it was run

A URL that starts with the URL scheme and scheme specific part (http://, https://, ftp://, etc.) is an absolute URL.

Any other URL is a relative URL and needs a base URL the relative URL is resolved from (and thus depend on) that is the URL of the resource the reference is used in if not declared otherwise.

Take a look at RFC 2396 – Appendix C for examples of resolving relative URLs.

First of all, 2 thing that we need to understand

Client

• it make request to specific server

  bindService(new 
      Intent("com.android.vending.billing.InAppBillingService.BIND"),
          mServiceConn, Context.BIND_AUTO_CREATE);`
  

here mServiceConn is instance of ServiceConnection class(inbuilt) it is actually interface that we need to implement with two (1st for network connected and 2nd network not connected) method to monitor network connection state.

Server

• It handle the request of client and make replica of it's own which is private to client only who send request and this replica of server runs on different thread.

Now at client side, how to access all the method of server?

• server send response with IBind Object.so IBind object is our handler which access all the method of service by using (.) operator.

  MyService myService;
  public ServiceConnection myConnection = new ServiceConnection() {
      public void onServiceConnected(ComponentName className, IBinder binder) {
          Log.d("ServiceConnection","connected");
          myService = binder;
      }
      //binder comes from server to communicate with method's of 
  
      public void onServiceDisconnected(ComponentName className) {
          Log.d("ServiceConnection","disconnected");
          myService = null;
      }
  }
  

now how to call method which lies in service

myservice.serviceMethod();

here myService is object and serviceMethode is method in service. And by this way communication is established between client and server.

Had same problem with psql via command line connecting and pgAdmin not connecting on RDS with AWS. I did have my RDS set to Publicly Accessible. I made sure my ACL and security groups were wide open and still problem so, I did the following: sudo find . -name *.conf then sudo nano ./data/pg_hba.conf then added to top of directives in pg_hba.conf file host all all 0.0.0.0/0 md5 and pgAdmin automatically logged me in.

This also worked in pg_hba.conf file host all all md5 without any IP address and this also worked with my IP address host all all <myip>/32 md5

As a side note, my RDS was in my default VPC. I had an identical RDS instance in my non-default VPC with identical security group, ACL and security group settings to my default VPC and I could not get it to work. Not sure why but, that's for another day.

I just get it working by including select2.min.css

If you are using Toolbar, you don't need those solutions. You only have to change the theme of the toolbar

app:theme="@style/ThemeOverlay.AppCompat.Light"

app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"

If you are using a dark.actionBar your back button is going to be white else if you are using light actionbar theme it is going to be black.

I believe it was already mentioned in other threads:

calc(){ awk "BEGIN { print "$*" }"; }

then you can simply type :

calc 7.5/3.2
  2.34375

In your case it will be:

x=20; y=3;
calc $x/$y

or if you prefer, add this as a separate script and make it available in $PATH so you will always have it in your local shell:

#!/bin/bash
calc(){ awk "BEGIN { print $* }"; }

Event listeners

First off it's important to understand that there are two kinds of "event listeners":

1. Scope event listeners registered via $on:

   $scope.$on('anEvent', function (event, data) {
     ...
   });
   

2. Event handlers attached to elements via for example on or bind:

   element.on('click', function (event) {
     ...
   });
   

$scope.$destroy()

When $scope.$destroy() is executed it will remove all listeners registered via $on on that $scope.

It will not remove DOM elements or any attached event handlers of the second kind.

This means that calling $scope.$destroy() manually from example within a directive's link function will not remove a handler attached via for example element.on, nor the DOM element itself.

element.remove()

Note that remove is a jqLite method (or a jQuery method if jQuery is loaded before AngularjS) and is not available on a standard DOM Element Object.

When element.remove() is executed that element and all of its children will be removed from the DOM together will all event handlers attached via for example element.on.

It will not destroy the $scope associated with the element.

To make it more confusing there is also a jQuery event called $destroy. Sometimes when working with third-party jQuery libraries that remove elements, or if you remove them manually, you might need to perform clean up when that happens:

element.on('$destroy', function () {
  scope.$destroy();
});

What to do when a directive is "destroyed"

This depends on how the directive is "destroyed".

A normal case is that a directive is destroyed because ng-view changes the current view. When this happens the ng-view directive will destroy the associated $scope, sever all the references to its parent scope and call remove() on the element.

This means that if that view contains a directive with this in its link function when it's destroyed by ng-view:

scope.$on('anEvent', function () {
 ...
});

element.on('click', function () {
 ...
});

Both event listeners will be removed automatically.

However, it's important to note that the code inside these listeners can still cause memory leaks, for example if you have achieved the common JS memory leak pattern circular references.

Even in this normal case of a directive getting destroyed due to a view changing there are things you might need to manually clean up.

For example if you have registered a listener on $rootScope:

var unregisterFn = $rootScope.$on('anEvent', function () {});

scope.$on('$destroy', unregisterFn);

This is needed since $rootScope is never destroyed during the lifetime of the application.

The same goes if you are using another pub/sub implementation that doesn't automatically perform the necessary cleanup when the $scope is destroyed, or if your directive passes callbacks to services.

Another situation would be to cancel $interval/$timeout:

var promise = $interval(function () {}, 1000);

scope.$on('$destroy', function () {
  $interval.cancel(promise);
});

If your directive attaches event handlers to elements for example outside the current view, you need to manually clean those up as well:

var windowClick = function () {
   ...
};

angular.element(window).on('click', windowClick);

scope.$on('$destroy', function () {
  angular.element(window).off('click', windowClick);
});

These were some examples of what to do when directives are "destroyed" by Angular, for example by ng-view or ng-if.

If you have custom directives that manage the lifecycle of DOM elements etc. it will of course get more complex.

You may use simplehtmldom. Most of the jQuery selectors are supported in simplehtmldom. An example is given below

// Create DOM from URL or file
$html = file_get_html('http://www.google.com/');

// Find all images
foreach($html->find('img') as $element)
       echo $element->src . '<br>';

// Find all links
foreach($html->find('a') as $element)
       echo $element->href . '<br>'; 

More accurately anything that is not 0 is true.

So 1 is true, but so is 2, 3 ... etc.

If array elements don't contain spaces, another (perhaps more readable) solution would be:

if echo ${arr[@]} | grep -q -w "d"; then 
    echo "is in array"
else 
    echo "is not in array"
fi

Use cookielib. The linked doc page provides examples at the end. You'll also find a tutorial here.

You can try string.strip()
It worked for me! :)

In addition to @Jon Skeet's answer:

Traditionally Windows has used \r\n, Unix \n and Mac \r, however newer Macs use \n as they're unix based.

This is another example of how to use keySet(), get(), values() and entrySet() functions to obtain Keys and Values in a Map:

        Map<Integer, String> testKeyset = new HashMap<Integer, String>();

        testKeyset.put(1, "first");
        testKeyset.put(2, "second");
        testKeyset.put(3, "third");
        testKeyset.put(4, "fourth");

        // Print a single value relevant to a specified Key. (uses keySet())
        for(int mapKey: testKeyset.keySet())
            System.out.println(testKeyset.get(mapKey));

        // Print all values regardless of the key.
        for(String mapVal: testKeyset.values())
            System.out.println(mapVal.trim());

        // Displays the Map in Key-Value pairs (e.g: [1=first, 2=second, 3=third, 4=fourth])
        System.out.println(testKeyset.entrySet());

An ASP.NET HTTP handler is the process (frequently referred to as the "endpoint") that runs in response to a request made to an ASP.NET Web application. The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page via the page handler.

The ASP.NET page handler is only one type of handler. ASP.NET comes with several other built-in handlers such as the Web service handler for .asmx files.

You can create custom HTTP handlers when you want special handling that you can identify using file name extensions in your application. For example, the following scenarios would be good uses of custom HTTP handlers:

RSS feeds To create an RSS feed for a site, you can create a handler that emits RSS-formatted XML. You can then bind the .rss extension (for example) in your application to the custom handler. When users send a request to your site that ends in .rss, ASP.NET will call your handler to process the request.

Image server If you want your Web application to serve images in a variety of sizes, you can write a custom handler to resize images and then send them back to the user as the handler's response.

HTTP handlers have access to the application context, including the requesting user's identity (if known), application state, and session information. When an HTTP handler is requested, ASP.NET calls the ProcessRequest method on the appropriate handler. The handler's ProcessRequest method creates a response, which is sent back to the requesting browser. As with any page request, the response goes through any HTTP modules that have subscribed to events that occur after the handler has run.

Most simple solution Activator.CreateInstance<T>()

To display a value nicely, you can use the pprint module. The easiest way to dump all variables with it is to do

from pprint import pprint

pprint(globals())
pprint(locals())

If you are running in CGI, a useful debugging feature is the cgitb module, which displays the value of local variables as part of the traceback.

I had a same problem and this fixed it:

You should add:

This is a known bug at MySQL.

bug 40477

As you can see this has been a known issue since 2008 and they have not fixed it yet!!!

WORK AROUND
You first need to create the database to import. It doesn't need any tables. Then you can import your database.

1. first start your MySQL command line (apply username and password if you need to)
   C:\>mysql -u user -p

2. Create your database and exit

   mysql> DROP DATABASE database;  
   mysql> CREATE DATABASE database;  
   mysql> Exit  
   

3. Import your selected database from the dump file
   C:\>mysql -u user -p -h localhost -D database -o < dumpfile.sql

You can replace localhost with an IP or domain for any MySQL server you want to import to. The reason for the DROP command in the mysql prompt is to be sure we start with an empty and clean database.

+ theme(plot.title = element_text(size=22))

Here is the full set of things you can change in element_text:

element_text(family = NULL, face = NULL, colour = NULL, size = NULL,
  hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
  color = NULL)

If you don't know what the URL parameters will be and want to get an object with the keys and values that are in the parameters, you can use this:

function getParameters() {
  var searchString = window.location.search.substring(1),
      params = searchString.split("&"),
      hash = {};

  if (searchString == "") return {};
  for (var i = 0; i < params.length; i++) {
    var val = params[i].split("=");
    hash[unescape(val[0])] = unescape(val[1]);
  }
  return hash;
}

Calling getParameters() with a url like /posts?date=9/10/11&author=nilbus would return:

{
  date:   '9/10/11',
  author: 'nilbus'
}

I won't include the code here since it's even farther away from the question, but weareon.net posted a library that allows manipulation of the parameters in the URL too:

• Blog post: http://blog.weareon.net/working-with-url-parameters-in-javascript/
• Code: http://pastebin.ubuntu.com/1163515/

As a supplement to above answers - I'm just bumping into a similar problem, and working completely of the default installed python.

When I call the example of the shared object library I'm looking for with LD_LIBRARY_PATH, I get something like this:

$ LD_LIBRARY_PATH=/path/to/mysodir:$LD_LIBRARY_PATH python example-so-user.py
python: can't open file 'example-so-user.py': [Errno 2] No such file or directory

Notably, it doesn't even complain about the import - it complains about the source file!

But if I force loading of the object using LD_PRELOAD:

$ LD_PRELOAD=/path/to/mysodir/mypyobj.so python example-so-user.py
python: error while loading shared libraries: libtiff.so.5: cannot open shared object file: No such file or directory

... I immediately get a more meaningful error message - about a missing dependency!

Just thought I'd jot this down here - cheers!

One approach:

(
  shopt -s nullglob
  files=(/home/edward/bank1/fiche/Test*)
  if [[ "${#files[@]}" -gt 0 ]] ; then
    echo found one
  else
    echo found none
  fi
)

Explanation:

• shopt -s nullglob will cause /home/edward/bank1/fiche/Test* to expand to nothing if no file matches that pattern. (Without it, it will be left intact.)
• ( ... ) sets up a subshell, preventing shopt -s nullglob from "escaping".
• files=(/home/edward/bank1/fiche/Test*) puts the file-list in an array named files. (Note that this is within the subshell only; files will not be accessible after the subshell exits.)
• "${#files[@]}" is the number of elements in this array.

Edited to address subsequent question ("What if i also need to check that these files have data in them and are not zero byte files"):

For this version, we need to use -s (as you did in your question), which also tests for the file's existence, so there's no point using shopt -s nullglob anymore: if no file matches the pattern, then -s on the pattern will be false. So, we can write:

(
  found_nonempty=''
  for file in /home/edward/bank1/fiche/Test* ; do
    if [[ -s "$file" ]] ; then
      found_nonempty=1
    fi
  done
  if [[ "$found_nonempty" ]] ; then
    echo found one
  else
    echo found none
  fi
)

(Here the ( ... ) is to prevent file and found_file from "escaping".)

Check out the implode() function as an alternative. This will convert the array into a list. The first param is how you want the items separated. Here I have used a comma with a space after it.

$invite = implode(', ', $_POST['invite']);
echo $invite;

Please try this code

new_column=df[['col1', 'col2', 'col3', 'col4']].groupby(['col1', 'col2']).count()
df['count_it']=new_column
df

I think that code will add a column called 'count it' which count of each group

There's a tagName property, and a attributes property as well:

var element = document.getElementById("wtv");
var openTag = "<"+element.tagName;
for (var i = 0; i < element.attributes.length; i++) {
    var attrib = element.attributes[i];
    openTag += " "+attrib.name + "=" + attrib.value;
}
openTag += ">";
alert(openTag);

See also How to iterate through all attributes in an HTML element? (I did!)

To get the contents between the open and close tags you could probably use innerHTML if you don't want to iterate over all the child elements...

alert(element.innerHTML);

... and then get the close tag again with tagName.

var closeTag = "</"+element.tagName+">";
alert(closeTag);

Here is my first stab at this in the swift playground. I extend String by providing two new functions (contains and containsIgnoreCase)

extension String {
    func contains(other: String) -> Bool{
        var start = startIndex

        do{
            var subString = self[Range(start: start++, end: endIndex)]
            if subString.hasPrefix(other){
                return true
            }

        }while start != endIndex

        return false
    }

    func containsIgnoreCase(other: String) -> Bool{
        var start = startIndex

        do{
            var subString = self[Range(start: start++, end: endIndex)].lowercaseString
            if subString.hasPrefix(other.lowercaseString){
                return true
            }

        }while start != endIndex

        return false
    }
}

Use it like this

var sentence = "This is a test sentence"
sentence.contains("this")  //returns false
sentence.contains("This")  //returns true
sentence.containsIgnoreCase("this")  //returns true

"This is another test sentence".contains(" test ")    //returns true

I'd welcome any feedback :)

For Google travelers: this stupidly unhelpful error message is also presented when you make a type and double up the + regex operator:

Okay:

\w+

Not okay:

\w++

So, perhaps this is a bit clunky but so far so good. Im working in angular 9.

file .ts

scroll(el: HTMLElement) {
  el.scrollIntoView({ block: 'start',  behavior: 'smooth' });   
}

file .html

<button (click)="scroll(target)"></button>
<div  #target style="margin-top:-50px;padding-top: 50px;" ></div>

I adjust the offset with margin and padding top.

Use stream to write content to webrequest

string data = "username=<value>&password=<value>"; //replace <value>
byte[] dataStream = Encoding.UTF8.GetBytes(data);
private string urlPath = "http://xxx.xxx.xxx/manager/";
string request = urlPath + "index.php/org/get_org_form";
WebRequest webRequest = WebRequest.Create(request);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = dataStream.Length;  
Stream newStream=webRequest.GetRequestStream();
// Send the data.
newStream.Write(dataStream,0,dataStream.Length);
newStream.Close();
WebResponse webResponse = webRequest.GetResponse();  

Just replacing "Please enter your name" to your desired content would do the job. Am I missing something?

    "cb" => $cb,
    "value" => "ajax2"
    );      

    //encoding array in JSON format
    echo json_encode($json);
?>

why not simply just give the input field where you want to jump to a id and do a simple focus

$("#newListField").focus();

You can't do it because you can't have control on the manner Chrome opens its windows

Set the user name as data-username attribute to the button and also a class:

HTML

<input type="button" name="theButton" value="Detail" class="btn" data-username="{{result['username']}}" />

JS

$(document).on('click', '.btn', function() {

    var name = $(this).data('username');        
    if (name != undefined && name != null) {
        window.location = '/player_detail?username=' + name;
    }
});?

EDIT:

Also, you can simply check for undefined && null using:

$(document).on('click', '.btn', function() {

    var name = $(this).data('username');        
    if (name) {
        window.location = '/player_detail?username=' + name;
    }
});?

As, mentioned in this answer

if (name) {            
}

will evaluate to true if value is not:

• null
• undefined
• NaN
• empty string ("")
• 0
• false

The above list represents all possible falsy values in ECMA/Javascript.

You have not given us your representation of a polygon. So I am choosing (more like suggesting) one for you :)

Represent each polygon as one big convex polygon, and a list of smaller convex polygons which need to be 'subtracted' from that big convex polygon.

Now given two polygons in that representation, you can compute the intersection as:

Compute intersection of the big convex polygons to form the big polygon of the intersection. Then 'subtract' the intersections of all the smaller ones of both to get a list of subracted polygons.

You get a new polygon following the same representation.

Since convex polygon intersection is easy, this intersection finding should be easy too.

This seems like it should work, but I haven't given it more deeper thought as regards to correctness/time/space complexity.

As a rule of thumb, the safest bet towards making your document be treated properly by all web servers, proxies, and client browsers, is probably the following:

1. Use the application/xml content type
2. Include a character encoding in the content type, probably UTF-8
3. Include a matching character encoding in the encoding attribute of the XML document itself.

In terms of the RFC 3023 spec, which some browsers fail to implement properly, the major difference in the content types is in how clients are supposed to treat the character encoding, as follows:

For application/xml, application/xml-dtd, application/xml-external-parsed-entity, or any one of the subtypes of application/xml such as application/atom+xml, application/rss+xml or application/rdf+xml, the character encoding is determined in this order:

1. the encoding given in the charset parameter of the Content-Type HTTP header
2. the encoding given in the encoding attribute of the XML declaration within the document,
3. utf-8.

For text/xml, text/xml-external-parsed-entity, or a subtype like text/foo+xml, the encoding attribute of the XML declaration within the document is ignored, and the character encoding is:

1. the encoding given in the charset parameter of the Content-Type HTTP header, or
2. us-ascii.

Most parsers don't implement the spec; they ignore the HTTP Context-Type and just use the encoding in the document. With so many ill-formed documents out there, that's unlikely to change any time soon.

Anyone using JavaScript (as opposed to JQuery), might like to try this solution, where 'models' is the ID of the select field containing the list :-

var DDlist = document.getElementById("models");
while(DDlist.length>0){DDlist.remove(0);}

The answers above are correct: it is used in exception handling. The manual for GCC version 6 has more information (which is no longer present in the version 7 manual). The error can arise when linking an external function that - unknown to GCC - throws Java exceptions.

Subscript out of Range error occurs when you try to reference an Index for a collection that is invalid.

Most likely, the index in Windows does not actually include .xls. The index for the window should be the same as the name of the workbook displayed in the title bar of Excel.

As a guess, I would try using this:

Windows("Data Sheet - " & ComboBox_Month.Value & " " & TextBox_Year.Value).Activate

The problem here is that you have defined ID as a field in your data file when what you want is to just use an expression without any data from the data file. You can fix this by defining ID as an expression (or a sequence in this case)

ID EXPRESSION "ID_SEQ.nextval"

or

ID SEQUENCE(count)

For me, the problem was incorrect content type of the served .css file (if it included certain unicode characters).

Changing the content-type to text/css solved the problem.

Out of your comments to Mike Monkiewicz answer I suggest to use a simpler model: Use regular development branches, but use the squash option of the merge to get a single commit in your master branch:

git checkout -b bug1    # create the development branch
* hack hack hack *      # do some work
git commit
* hack hack hack *
git commit
* hack hack hack *
git commit
* hack hack hack *
git commit
git checkout master     # go back to the master branch
git merge --squash bug1 # merge the work back
git commit              # commit the merge (don't forget
                        #    to change the default commit message)
git branch -D bug1      # remove the development branch

The advantage of this procedure is that you can use the normal git work flow.

I thought I could add a method I use in many projects.

- (NSInteger)randomValueBetween:(NSInteger)min and:(NSInteger)max {
    return (NSInteger)(min + arc4random_uniform(max - min + 1));
}

If I end up using it in many files I usually declare a macro as

#define RAND_FROM_TO(min, max) (min + arc4random_uniform(max - min + 1))

E.g.

NSInteger myInteger = RAND_FROM_TO(0, 74) // 0, 1, 2,..., 73, 74

Yup. Function references are just like any other object reference, you can pass them around to your heart's content.

Here's a more concrete example:

function foo() {
    console.log("Hello from foo!");
}

function caller(f) {
    // Call the given function
    f();
}

function indirectCaller(f) {
    // Call `caller`, who will in turn call `f`
    caller(f);
}

// Do it
indirectCaller(foo); // logs "Hello from foo!"

You can also pass in arguments for foo:

function foo(a, b) {
    console.log(a + " + " + b + " = " + (a + b));
}

function caller(f, v1, v2) {
    // Call the given function
    f(v1, v2);
}

function indirectCaller(f, v1, v2) {
    // Call `caller`, who will in turn call `f`
    caller(f, v1, v2);
}

// Do it
indirectCaller(foo, 1, 2); // logs "1 + 2 = 3"

Another option to consider is disabling it when you do not want it to be able to be changed and enabling it:

//When select should be disabled:
{
    $('#my_select').attr('disabled', 'disabled');
}

//When select should not be disabled
{
    $('#my_select').removeAttr('disabled');
}

Update since your comment (if I understand the functionality you want):

$("#dropdown").change(function()
{
    var answer = confirm("Are you sure you want to change your selection?")
    {
        if(answer)
        {
            //Update dropdown (Perform update logic)
        }
        else
        {
            //Allow Change (Do nothing - allow change)
        } 
    }            
});

Here is how I solve this. I just pipe the output to Out-String and then pass that output to the .NET Trim function:

(gci | ft -HideTableHeaders | Out-String).Trim()

This will strip out the line breaks before and after the table.

You can also use TrimStart to just take care of the header's line break if you still want the trailing line breaks.

(gci | ft -HideTableHeaders | Out-String).TrimStart()

you can do like follows. Remember, IsNull is a function which returns TRUE if the parameter passed to it is null, and false otherwise.

Not IsNull(Fields!W_O_Count.Value)

$time = strtotime(date('2016-02-03 12:00:00'));
        echo date("H:i:s",strtotime("-30 minutes", $time));

this nsdate used different format:

NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setDateFormat:@"MMM dd, yyyy HH:mm"];

NSDate *now = [[NSDate alloc] init];

NSString *dateString = [format stringFromDate:now];

NSDateFormatter *inFormat = [[NSDateFormatter alloc] init];
[inFormat setDateFormat:@"MMM dd, yyyy"];

NSDate *parsed = [inFormat dateFromString:dateString]; 

If you don't need the DATETIME value in the rest of your code, it'd be more efficient, simple and secure to use an UPDATE query with a sub-select, something like

UPDATE products SET t=(SELECT f FROM products WHERE id=17) WHERE id=42;

or in case it's in the same row in a single table, just

UPDATE products SET t=f WHERE id=42;

Try this:

{
    "ACCOUNT_EXIST": true,
    "MultipleContacts": false
}

boolean success ((Boolean) jsonObject.get("ACCOUNT_EXIST")).booleanValue()

Assuming the first answer is referring to the C-like syntax (char *)(0x135700 +0xec1a04f) then the answer to do rwatch *0x135700+0xec1a04f is incorrect. The correct syntax is rwatch *(0x135700+0xec1a04f).

The lack of ()s there caused me a great deal of pain trying to use watchpoints myself.

If you are not allowed to change the buffer limit at the server level, you will need to use the <%Response.Buffer = False%> method.

HOWEVER, if you are still getting this error and have a large table on the page, the culprit may be table itself. By design, some versions of Internet Explorer will buffer the entire content between before it is rendered to the page. So even if you are telling the page to not buffer the content, the table element may be buffered and causing this error.

Some alternate solutions may be to paginate the table results, but if you must display the entire table and it has thousands of rows, throw this line of code in the middle of the table generation loop: <% Response.Flush %>. For speed considerations, you may also want to consider adding a basic counter so that the flush only happens every 25 or 100 lines or so.

Drawbacks of not buffering the output:

1. slowdown of overall page load
2. tables and columns will adjust their widths as content is populated (table appears to wiggle)
3. Users will be able to click on links and interact with the page before it is fully loaded. So if you have some javascript at the bottom of the page, you may want to move it to the top to ensure it is loaded before some of your faster moving users click on things.

Hope that helps.

As hoijui mentions. The selected answer from Stephen Katulka contains a comment about Collections.copy that is incorrect. The author probably accepted it because the first line of code was doing the copy that he wanted. The additional call to Collections.copy just copies again. (Resulting in the copy happening twice).

Here is code to prove it.

public static void main(String[] args) {

    List<String> a = new ArrayList<String>();
    a.add("a");
    a.add("b");
    a.add("c");
    List<String> b = new ArrayList<String>(a);

    System.out.println("There should be no output after this line.");

    // Note, b is already a shallow copy of a;
    for (int i = 0; i < a.size(); i++) {
        if (a.get(i) != b.get(i)) {
            System.out.println("Oops, this was a deep copy."); // Note this is never called.
        }
    }

    // Now use Collections.copy and note that b is still just a shallow copy of a
    Collections.copy(b, a);
    for (int i = 0; i < a.size(); i++) {
        if (a.get(i) != b.get(i)) {
            System.out.println("Oops, i was wrong this was a deep copy"); // Note this is never called.
        }
    }

    // Now do a deep copy - requires you to explicitly copy each element
    for (int i = 0; i < a.size(); i++) {
        b.set(i, new String(a.get(i)));
    }

    // Now see that the elements are different in each 
    for (int i = 0; i < a.size(); i++) {
        if (a.get(i) == b.get(i)) {
            System.out.println("oops, i was wrong, a shallow copy was done."); // note this is never called.
        }
    }
}

According to the Documentation :

MailMessage.To property - Returns MailAddressCollection that contains the list of recipients of this email message

Here MailAddressCollection has a in built method called

   public void Add(string addresses)

   1. Summary:
          Add a list of email addresses to the collection.

   2. Parameters:
          addresses: 
                *The email addresses to add to the System.Net.Mail.MailAddressCollection. Multiple
                *email addresses must be separated with a comma character (",").     

Therefore requirement in case of multiple recipients : Pass a string that contains email addresses separated by comma

In your case :

simply replace all the ; with ,

Msg.To.Add(toEmail.replace(";", ","));

If you will use only Vidar Wahlberg answer, you get error when you open other activity (for example) and back to map. Or in my case open other activity and then from new activity open map again( without use back button). But when you combine Vidar Wahlberg solution and Matt solution you will have not exceptions.

        getFragmentManager().beginTransaction().remove(fragment).commit();
}

Just change the first line as follows :

include ActionView::Helpers

that will make it works.

UPDATE: For Rails 3 use:

ActionController::Base.helpers.sanitize(str)

You need to add annotations to the Junit class, telling it to use the SpringJunitRunner. The ones you want are:

@ContextConfiguration("/test-context.xml")
@RunWith(SpringJUnit4ClassRunner.class)

This tells Junit to use the test-context.xml file in same directory as your test. This file should be similar to the real context.xml you're using for spring, but pointing to test resources, naturally.

You are dynamically generating those elements so any listener applied on page load wont be available. I have edited your fiddle with the correct solution. Basically jQuery holds the event for later binding by attaching it to the parent Element and propagating it downward to the correct dynamically created element.

$('#musics').on('change', '#want',function(e) {
    $(this).closest('.from-group').val(($('#want').is(':checked')) ? "yes" : "no");
    var ans=$(this).val();
    console.log(($('#want').is(':checked')));
});

var _href = $("a.directions-link").attr("href");
$("a.directions-link").attr("href", _href + '&saddr=50.1234567,-50.03452');

To loop with each()

$("a.directions-link").each(function() {
   var $this = $(this);       
   var _href = $this.attr("href"); 
   $this.attr("href", _href + '&saddr=50.1234567,-50.03452');
});

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Variant

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    rowNum = Application.Match(aNumber, rng, 0)

    If Not IsError(rowNum) Then
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

Delete the working copy from the OS and check it out again is simplest, but obviously not a single command.

Easiest way is replace this default bootstrap code:

<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
</button>

by this :

<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="" role="button" ><i class="fa fa-bars" aria-hidden="true" style="color:#e6e6ff"></i></span>
</button>

And don't forget to add this code also to your file:

Be warned - this is a very old and cumbersome "solution".

By the way, you can use serialization technology to send strings, numbers or any objects which are support serialization (most of .NET data-storing classes & structs are [Serializable]). There, you should at first send Int32-length in four bytes to the stream and then send binary-serialized (System.Runtime.Serialization.Formatters.Binary.BinaryFormatter) data into it.

On the other side or the connection (on both sides actually) you definetly should have a byte[] buffer which u will append and trim-left at runtime when data is coming.

Something like that I am using:

namespace System.Net.Sockets
{
    public class TcpConnection : IDisposable
    {
        public event EvHandler<TcpConnection, DataArrivedEventArgs> DataArrive = delegate { };
        public event EvHandler<TcpConnection> Drop = delegate { };

        private const int IntSize = 4;
        private const int BufferSize = 8 * 1024;

        private static readonly SynchronizationContext _syncContext = SynchronizationContext.Current;
        private readonly TcpClient _tcpClient;
        private readonly object _droppedRoot = new object();
        private bool _dropped;
        private byte[] _incomingData = new byte[0];
        private Nullable<int> _objectDataLength;

        public TcpClient TcpClient { get { return _tcpClient; } }
        public bool Dropped { get { return _dropped; } }

        private void DropConnection()
        {
            lock (_droppedRoot)
            {
                if (Dropped)
                    return;

                _dropped = true;
            }

            _tcpClient.Close();
            _syncContext.Post(delegate { Drop(this); }, null);
        }

                    TcpClient.Client.BeginSend(BitConverter.GetBytes(bytedata.Length), 0, IntSize, SocketFlags.None, EndSend, null);
                    TcpClient.Client.BeginSend(bytedata, 0, bytedata.Length, SocketFlags.None, EndSend, null);
                }
            }

That is just an example, you should edit it for your use.

Sorry, but I have to chime in. I have been through several of the suggested solutions, before finding the Prism.Wpf.Interactivity namespace in the Prism project. You can use interaction requests and popup window action to either roll a custom window or for simpler needs there are built in Notification and Confirmation popups. These create true windows and are managed as such. you can pass a context object with any dependencies you need in the dialog. We use this solution at my work since I found it. We have numerous senior devs here and noone has come up with anything better. Our previous solution was the dialog service into an overlay and using a presenter class to make it happen, but you had to have factories for all of the dialog viewmodels, etc.

This isn't trivial but it also isn't super complicated. And it is built in to Prism and is therefore best (or better) practice IMHO.

My 2 cents!

You can use % operator to check divisiblity of a given number

The code to check whether given no. is divisible by 3 or 5 when no. less than 1000 is given below:

n=0
while n<1000:
    if n%3==0 or n%5==0:
        print n,'is multiple of 3 or 5'
    n=n+1

As long as the script is after the img, then:

var youtubeimgsrc = document.getElementById("youtubeimg").src;

See getElementById in the DOM specification.

If the script is before the img, then of course the img doesn't exist yet, and that doesn't work. This is one reason why many people recommend putting scripts at the end of the body element.

Side note: It doesn't matter in your case because you've used an absolute URL, but if you used a relative URL in the attribute, like this:

<img id="foo" src="/images/example.png">

...the src reflected property will be the resolved URL — that is, the absolute URL that that turns into. So if that were on the page http://www.example.com, document.getElementById("foo").src would give you "http://www.example.com/images/example.png".

If you wanted the src attribute's content as is, without being resolved, you'd use getAttribute instead: document.getElementById("foo").getAttribute("src"). That would give you "/images/example.png" with my example above.

If you have an absolute URL, like the one in your question, it doesn't matter.

Not pretty good solution, but you can try the hjson tool. It allows you to write text multi-lined in editor and then converts it to the proper valid JSON format.

Note: it adds '\n' characters for the new lines, but you can simply delete them in any text editor with the "Replace all.." function.

import os
for root, dirs, files in os.walk(top, topdown=False):
    for name in dirs:
        print os.path.join(root, name)

Walk is a good built-in for what you are doing

This is how to hide the first section header in UITableView (grouped style).

Swift 3.0 & Xcode 8.0 Solution

1. The TableView's delegate should implement the heightForHeaderInSection method

2. Within the heightForHeaderInSection method, return the least positive number. (not zero!)

   func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
   
       let headerHeight: CGFloat
   
       switch section {
       case 0:
           // hide the header
           headerHeight = CGFloat.leastNonzeroMagnitude
       default:
           headerHeight = 21
       }
   
       return headerHeight
   }
   

This is worked with me

if (evt.xa.which == 3) 
{
    alert("Right mouse clicked");
}

var rowpos = $('#table tr:last').position();

$('#container').scrollTop(rowpos.top);

should do the trick!

If you want to show an image hosted at any website (say url is "http:// abc.def.com/folder/image.jpg") then in your README.md file use the below syntax:

![alt text](<http:// abc.def.com/folder/image.jpg>)

• Just browse to the image in your browser (may be by clicking on the image). It can be any website, including yours or somebody else's github hosted image.
• Copy the url from the browser address bar, that is your "image_url" to be used in above referred syntax.

For images hosted in your own github repository you can use relative path in addition to the above url format
![alt text](<path_relative_to_current_github_location/image.jpg>)

Note the angular brackets "<" and ">" enclosing the url. Sometimes these are required for the url to work.

This works for me on all browsers and Jquery <= v1.10

$('#kat').on('keyup', function () {
    alert("Hello");
});

or as it seems you want

$('#kat').on('click', function () {
    alert("Hello");
});

Textbox input field change event fires as you would expect it to, the jQuery .Change event only works correctly on html5 supported browsers

I didn't get the interrupt to work in Android, so I used this method, works perfectly:

boolean shouldCheckUpdates = true;

private void startupCheckForUpdatesEveryFewSeconds() {
    Thread t = new Thread(new CheckUpdates());
    t.start();
}

private class CheckUpdates implements Runnable{
    public void run() {
        while (shouldCheckUpdates){
            //Thread sleep 3 seconds
            System.out.println("Do your thing here");
        }
    }
}

 public void stop(){
        shouldCheckUpdates = false;
 }

Not sure about your specific scenario, but you have three options:

1.) use Dictionary<..,..>
2.) create a wrapper class around your values and then you can use List
3.) use Tuple

Java is a kind of object-oriented programming, not a procedure programming. So every thing in your code should be manipulating an object.

public static void main is only the entry of your program. It does not involve any object behind.

So what is coding with an object? It is simple, you need to create a particular object/instance, call their methods to change their states, or do other specific function within that object.

e.g. just like

private ReportHandler rh = new ReportHandler();
rh.<function declare in your Report Handler class>

So when you declare a static method, it doesn't associate with your object/instance of your object. And it is also violate with your O-O programming.

static method is usually be called when that function is not related to any object behind.

If you´ve already defined a DataSource, You can get the DataGridView´s DataSource and cast it as a Datatable.

Then add a new DataRow and set the Fields Values.

Add the new row to the DataTable and Accept the changes.

In C# it would be something like this..

DataTable dataTable = (DataTable)dataGridView.DataSource;
DataRow drToAdd = dataTable.NewRow();

drToAdd["Field1"] = "Value1";
drToAdd["Field2"] = "Value2";

dataTable.Rows.Add(drToAdd);
dataTable.AcceptChanges();

rpm -ql [packageName]

Example

# rpm -ql php-fpm

/etc/php-fpm.conf
/etc/php-fpm.d
/etc/php-fpm.d/www.conf

No need to install yum-utils, or to know the location of the rpm file.

1. Basic validation can be performed by choosing the type attribute of input elements. For example: <input type="email" /> <input type="URL" /> <input type="number" />

2. using pattern attribute like: <input type="text" pattern="[1-4]{5}" />

3. required attribute <input type="text" required />

4. maxlength: <input type="text" maxlength="20" />

5. min & max: <input type="number" min="1" max="4" />

As long as adding clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true); on client creation solved the issue for me:

ClientConfig clientConfig = new DefaultClientConfig();
clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);
Client client = Client.create(clientConfig);

This is the best way to detect Bearing from Location Object on Google Map:->

 float targetBearing=90;

      Location endingLocation=new Location("ending point"); 

      Location
       startingLocation=new Location("starting point");
       startingLocation.setLatitude(mGoogleMap.getCameraPosition().target.latitude);
       startingLocation.setLongitude(mGoogleMap.getCameraPosition().target.longitude);
       endingLocation.setLatitude(mLatLng.latitude);
       endingLocation.setLongitude(mLatLng.longitude);
      targetBearing =
       startingLocation.bearingTo(endingLocation);

The ThreadPool.QueueUserWorkItem is pretty ideal for something simple. The only caveat is accessing a control from the other thread.

System.Threading.ThreadPool.QueueUserWorkItem(delegate {
    DoSomethingThatDoesntInvolveAControl();
}, null);

Please let me complete the answer by @LukeH with some sample code, as I have tested it I believe it may be useful for some:

public class Order
{
    public string OrderId { get; set; }
    public DateTime OrderDate { get; set; }
    public int Quantity { get; set; }
    public int Total { get; set; }

    public Order(string orderId, DateTime orderDate, int quantity, int total)
    {
        OrderId = orderId;
        OrderDate = orderDate;
        Quantity = quantity;
        Total = total;
    }
}

public void SampleDataAndTest()
{
    List<Order> objListOrder = new List<Order>();

    objListOrder.Add(new Order("tu me paulo ", Convert.ToDateTime("01/06/2016"), 1, 44));
    objListOrder.Add(new Order("ante laudabas", Convert.ToDateTime("02/05/2016"), 2, 55));
    objListOrder.Add(new Order("ad ordinem ", Convert.ToDateTime("03/04/2016"), 5, 66));
    objListOrder.Add(new Order("collocationem ", Convert.ToDateTime("04/03/2016"), 9, 77));
    objListOrder.Add(new Order("que rerum ac ", Convert.ToDateTime("05/02/2016"), 10, 65));
    objListOrder.Add(new Order("locorum ; cuius", Convert.ToDateTime("06/01/2016"), 1, 343));


    Console.WriteLine("Sort the list by date ascending:");
    objListOrder.Sort((x, y) => x.OrderDate.CompareTo(y.OrderDate));

    foreach (Order o in objListOrder)
        Console.WriteLine("OrderId = " + o.OrderId + " OrderDate = " + o.OrderDate.ToString() + " Quantity = " + o.Quantity + " Total = " + o.Total);

    Console.WriteLine("Sort the list by date descending:");
    objListOrder.Sort((x, y) => y.OrderDate.CompareTo(x.OrderDate));
    foreach (Order o in objListOrder)
        Console.WriteLine("OrderId = " + o.OrderId + " OrderDate = " + o.OrderDate.ToString() + " Quantity = " + o.Quantity + " Total = " + o.Total);

    Console.WriteLine("Sort the list by OrderId ascending:");
    objListOrder.Sort((x, y) => x.OrderId.CompareTo(y.OrderId));
    foreach (Order o in objListOrder)
        Console.WriteLine("OrderId = " + o.OrderId + " OrderDate = " + o.OrderDate.ToString() + " Quantity = " + o.Quantity + " Total = " + o.Total);

    //etc ...

The short answer here is the serial ID is computed via a hash if you don't specify it. (Static members are not inherited--they are static, there's only (1) and it belongs to the class).

http://docs.oracle.com/javase/6/docs/platform/serialization/spec/class.html

The getSerialVersionUID method returns the serialVersionUID of this class. Refer to Section 4.6, "Stream Unique Identifiers." If not specified by the class, the value returned is a hash computed from the class's name, interfaces, methods, and fields using the Secure Hash Algorithm (SHA) as defined by the National Institute of Standards.

If you alter a class or its hierarchy your hash will be different. This is a good thing. Your objects are different now that they have different members. As such, if you read it back in from its serialized form it is in fact a different object--thus the exception.

The long answer is the serialization is extremely useful, but probably shouldn't be used for persistence unless there's no other way to do it. Its a dangerous path specifically because of what you're experiencing. You should consider a database, XML, a file format and probably a JPA or other persistence structure for a pure Java project.

Ok , I can control the width and height using Builder class. I used

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(layout);
builder.setTitle("Title");
AlertDialog alertDialog = builder.create();
alertDialog.getWindow().setLayout(600, 400); //Controlling width and height.
alertDialog.show();

Try this.

SELECT * FROM la_schedule WHERE `start_date` > '2012-11-18';

You can use flexbox with flex-grow to push the last element to the right.

<div style="display: flex;">
  <div style="flex-grow: 1;">Left</div>
  <div>Right</div>
</div>

geopoint = {'latitude':41.123,'longitude':71.091}

# working examples.
print(f'{geopoint["latitude"]} {geopoint["longitude"]}') # from above answer
print('{geopoint[latitude]} {geopoint[longitude]}'.format(geopoint=geopoint)) # alternate for format method  (including dict name in string).
print('%(latitude)s %(longitude)s'%geopoint) # thanks @tcll

For additional details see the SVNBook: "Status of working copy files and directories".

The common statuses:

U: Working file was updated

G: Changes on the repo were automatically merged into the working copy

M: Working copy is modified

C: This file conflicts with the version in the repo

?: This file is not under version control

!: This file is under version control but is missing or incomplete

A: This file will be added to version control (after commit)

A+: This file will be moved (after commit)

D: This file will be deleted (after commit)

S: This signifies that the file or directory has been switched from the path of the rest of the working copy (using svn switch) to a branch

I: Ignored

X: External definition

~: Type changed

R: Item has been replaced in your working copy. This means the file was scheduled for deletion, and then a new file with the same name was scheduled for addition in its place.

L : Item is locked

E: Item existed, as it would have been created, by an svn update.

From bash command line, run:

$ python -c "import nltk; nltk.download('punkt')"

Ok, here's a simple box that follows the cursor

Doing the rest is a simple case of remembering the last cursor position and applying a formula to get the box to move other than exactly where the cursor is. A timeout would also be handy if the box has a limited acceleration and must catch up to the cursor after it stops moving. Replacing the box with an image is simple CSS (which can replace most of the setup code for the box). I think the actual thinking code in the example is about 8 lines.

Select the right image (use a sprite) to orientate the rocket.

Yeah, annoying as hell. :-)

If your base class is called Base, and your function is called FooBar() you can call it directly using Base::FooBar()

void Base::FooBar()
{
   printf("in Base\n");
}

void ChildOfBase::FooBar()
{
  Base::FooBar();
}

I know a lot's of time has passed since this publish, but I've fallen in a similar situation and create a simples class to simplify my life.

                    finalText = finalText.stringByAppendingString(tempString.substringWithRange(pureStringRange))
                    tempIndex = tempIndex.advancedBy(1)
                }

Replace

f = open(D\\python\\HW\\2_1 - Copy.cp,"r");

by

f = open("D:\\python\\HW\\2_1 - Copy.cp", "r")

1. File path needs to be a string (constant)
2. need colon in Windows file path
3. space after comma for better style
4. ; after statement is allowed but fugly.

What tutorial are you using?

You can also keep the whole video, you do not have to cut something away.
You can overlay inset shadows over the white-blurred edges.

This looks really nice as well :)

Just paste this code to your videos' parent:

.parent {
    -webkit-box-shadow: inset 0 0 200px #000000;
       -moz-box-shadow: inset 0 0 200px #000000;
            box-shadow: inset 0 0 200px #000000;
}

Universal method

public static <K, V> Map<K, V> listAsMap(Collection<V> sourceList, ListToMapConverter<K, V> converter) {
    Map<K, V> newMap = new HashMap<K, V>();
    for (V item : sourceList) {
        newMap.put( converter.getKey(item), item );
    }
    return newMap;
}

public static interface ListToMapConverter<K, V> {
    public K getKey(V item);
}

If you have the product's ID you can use that to create a product object:

$_product = wc_get_product( $product_id );

Then from the object you can run any of WooCommerce's product methods.

$_product->get_regular_price();
$_product->get_sale_price();
$_product->get_price();

Update
Please review the Codex article on how to write your own shortcode.

Integrating the WooCommerce product data might look something like this:

function so_30165014_price_shortcode_callback( $atts ) {
    $atts = shortcode_atts( array(
        'id' => null,
    ), $atts, 'bartag' );

    $html = '';

    if( intval( $atts['id'] ) > 0 && function_exists( 'wc_get_product' ) ){
         $_product = wc_get_product( $atts['id'] );
         $html = "price = " . $_product->get_price();
    }
    return $html;
}
add_shortcode( 'woocommerce_price', 'so_30165014_price_shortcode_callback' );

Your shortcode would then look like [woocommerce_price id="99"]

Introduction to Algorithms by Cormen et. al. is a standard introductory algorithms book, and is used by many universities, including my own. It has pretty good coverage and is very approachable.

And anything by Robert Sedgewick is good too.

When you have changes on your working copy, from command line do:

git stash 

This will stash your changes and clear your status report

git pull

This will pull changes from upstream branch. Make sure it says fast-forward in the report. If it doesn't, you are probably doing an unintended merge

git stash pop

This will apply stashed changes back to working copy and remove the changes from stash unless you have conflicts. In the case of conflict, they will stay in stash so you can start over if needed.

if you need to see what is in your stash

git stash list

I'm looking into this as well, and while I don't have a good solution for you I did manage to dig up SIPDroid's video code:

http://code.google.com/p/sipdroid/source/browse/trunk/src/org/sipdroid/sipua/ui/VideoCamera.java

If no file available for download, I needed to disable the asp:linkButton, change it to grey and eliminate the underline on the hover. This worked:

.disabled {
    color: grey;
    text-decoration: none !important;
}

LinkButton button = item.FindControl("lnkFileDownload") as LinkButton;
button.Enabled = false;
button.CssClass = "disabled";

In your case I would consider using Set and not List, to ensure you have unique values only. unless you need sometimes to include duplicates.

In this case, you don't need to add any wrapper functions around lists.

new Date('1945/05/09').valueOf() < new Date('2011/05/09').valueOf()

How about $_SERVER ?

if (get_magic_quotes_gpc() === 1) {

    $_GET = json_decode(stripslashes(json_encode($_GET, JSON_HEX_APOS)), true);
    $_POST = json_decode(stripslashes(json_encode($_POST, JSON_HEX_APOS)), true);
    $_COOKIE = json_decode(stripslashes(json_encode($_COOKIE, JSON_HEX_APOS)), true);
    $_REQUEST = json_decode(stripslashes(json_encode($_REQUEST, JSON_HEX_APOS)), true); 
    $_SERVER = json_decode( stripslashes(json_encode($_SERVER,JSON_HEX_APOS)), true); 
}

Well, while googling about this throw specification, I had a look at this article :- (http://blogs.msdn.com/b/larryosterman/archive/2006/03/22/558390.aspx)

I am reproducing a part of it here also, so that it can be used in future irrespective of the fact that the above link works or not.

   class MyClass
   {
    size_t CalculateFoo()
    {
        :
        :
    };
    size_t MethodThatCannotThrow() throw()
    {
        return 100;
    };
    void ExampleMethod()
    {
        size_t foo, bar;
        try
        {
            foo = CalculateFoo();
            bar = foo * 100;
            MethodThatCannotThrow();
            printf("bar is %d", bar);
        }
        catch (...)
        {
        }
    }
};

When the compiler sees this, with the "throw()" attribute, the compiler can completely optimize the "bar" variable away, because it knows that there is no way for an exception to be thrown from MethodThatCannotThrow(). Without the throw() attribute, the compiler has to create the "bar" variable, because if MethodThatCannotThrow throws an exception, the exception handler may/will depend on the value of the bar variable.

In addition, source code analysis tools like prefast can (and will) use the throw() annotation to improve their error detection capabilities - for example, if you have a try/catch and all the functions you call are marked as throw(), you don't need the try/catch (yes, this has a problem if you later call a function that could throw).

Just replace below statement and it will work.

SimpleDateFormat formatDate = new SimpleDateFormat("hh:mm a");

I have added text in ToolBar :

menu_skip.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".MainActivity">

    <item
        android:id="@+id/action_settings"
        android:title="@string/text_skip"
        app:showAsAction="never" />
</menu>

MainActivity.java

@Override
boolean onCreateOptionsMenu(Menu menu) {
    inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_otp_skip, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        // action with ID action_refresh was selected
        case R.id.menu_item_skip:
            Toast.makeText(this, "Skip selected", Toast.LENGTH_SHORT)
                    .show();
            break;
        default:
            break;
    }
    return true;
}

If you want a super class to call a function from a subclass, the cleanest way is to define an abstract pattern, in this manner you explicitly know the method exists somewhere and must be overridden by a subclass.

This is as an example, normally you do not call a sub method within the constructor as the sub instance is not initialized yet… (reason why you have an "undefined" in your question's example)

abstract class A {
    // The abstract method the subclass will have to call
    protected abstract doStuff():void;

    constructor(){
     alert("Super class A constructed, calling now 'doStuff'")
     this.doStuff();
    }
}

class B extends A{

    // Define here the abstract method
    protected doStuff()
    {
        alert("Submethod called");
    }
}

var b = new B();

Test it Here

And if like @Max you really want to avoid implementing the abstract method everywhere, just get rid of it. I don't recommend this approach because you might forget you are overriding the method.

abstract class A {
    constructor() {
        alert("Super class A constructed, calling now 'doStuff'")
        this.doStuff();
    }

    // The fallback method the subclass will call if not overridden
    protected doStuff(): void {
        alert("Default doStuff");
    };
}

class B extends A {
    // Override doStuff()
    protected doStuff() {
        alert("Submethod called");
    }
}

class C extends A {
    // No doStuff() overriding, fallback on A.doStuff()
}

var b = new B();
var c = new C();

Try it Here

IF vertical align won't work use padding. padding-top: 10px; it will shift the text to the bottom or padding-bottom: 10px; to shift the text in the text box to top

adjust the padding size till it suit the size you want. Thats the hack

As Frank pointed out, you need to use DISTINCT. Also, since you are using composite primary keys (which is perfectly fine, BTW) you need to make sure that you use the whole key in your joins:

SELECT
    P.pe_name,
    COUNT(DISTINCT O.ord_id) AS num_orders,
    COUNT(I.item_id) AS num_items
FROM
    People P
INNER JOIN Orders O ON
    O.pe_id = P.pe_id
INNER JOIN Items I ON
    I.ord_id = O.ord_id AND
    I.pe_id = O.pe_id
GROUP BY
    P.pe_name

Without I.ord_id = O.ord_id it was joining each item row to every order row for a person.

Try to create script with ADD command and specification of working directory Like this("script" is the name of script and /root/script.sh is where you want it in the container, it can be different path:

ADD script.sh /root/script.sh

In this case ADD has to come before CMD, if you have one BTW it's cool way to import scripts to any location in container from host machine

In CMD place [./script]

It should automatically execute your script

You can also specify WORKDIR as /root, then you'l be automatically placed in root, upon starting a container

$(document).on('keyup keypress', 'form input[type="text"]', function(e) {
  if(e.which == 13) {
    e.preventDefault();
    return false;
  }
});

This solution works on all forms on website (also on forms inserted with ajax), preventing only Enters in input texts. Place it in a document ready function, and forget this problem for a life.

This should be simple using jquery:

HTML:

  <input type="text" name="txtJob" value="software engineer">

JS:

  var jobValue = $('#txtJob').val(); //Get the text field value
  $('#txtJob').val(jobValue);        //Set the text field value

JavaScript's forEach works a bit different from how one might be used to from other languages for each loops. If reading on the MDN, it says that a function is executed for each of the elements in the array, in ascending order. To continue to the next element, that is, run the next function, you can simply return the current function without having it do any computation.

Adding a return and it will go to the next run of the loop:

var myArr = [1,2,3,4];_x000D_
_x000D_
myArr.forEach(function(elem){_x000D_
  if (elem === 3) {_x000D_
    return;_x000D_
  }_x000D_
_x000D_
  console.log(elem);_x000D_
});

Output: 1, 2, 4

Try this:

@echo off
for /f "tokens=*" %%a in (input.txt) do (
  echo line=%%a
)
pause

because of the tokens=* everything is captured into %a

edit: to reply to your comment, you would have to do that this way:

@echo off
for /f "tokens=*" %%a in (input.txt) do call :processline %%a

pause
goto :eof

:processline
echo line=%*

goto :eof

:eof

Because of the spaces, you can't use %1, because that would only contain the part until the first space. And because the line contains quotes, you can also not use :processline "%%a" in combination with %~1. So you need to use %* which gets %1 %2 %3 ..., so the whole line.

I had much issues with this one too. I finally found out what's the final deal.

Referring to @Gokhan Oner answer, once you've got your Service class and the POJO representing your object, your YAML config file nice and lean, if you use the annotation @ConfigurationProperties, you have to explicitly get the object for being able to use it. Like :

@ConfigurationProperties(prefix = "available-payment-channels-list")
//@Configuration  <-  you don't specificly need this, instead you're doing something else
public class AvailableChannelsConfiguration {

    private String xyz;
    //initialize arraylist
    private List<ChannelConfiguration> channelConfigurations = new ArrayList<>();

    public AvailableChannelsConfiguration() {
        for(ChannelConfiguration current : this.getChannelConfigurations()) {
            System.out.println(current.getName()); //TADAAA
        }
    }

    public List<ChannelConfiguration> getChannelConfigurations() {
        return this.channelConfigurations;
    }

    public static class ChannelConfiguration {
        private String name;
        private String companyBankAccount;
    }

}

And then here you go. It's simple as hell, but we have to know that we must call the object getter. I was waiting at initialization, wishing the object was being built with the value but no. Hope it helps :)

Here's what I had to do to get this working. This means:

1. Custom UserNamePasswordValidator (no need for a Windows account, SQLServer or ActiveDirectory -- your UserNamePasswordValidator could have username & password hardcoded, or read it from a text file, MySQL or whatever).
2. https
3. IIS7
4. .net 4.0

My site is managed through DotNetPanel. It has 3 security options for virtual directories:

1. Allow Anonymous Access
2. Enable Basic Authentication
3. Enable Integrated Windows Authentication

Only "Allow Anonymous Access" is needed (although, that, by itself wasn't enough).

Setting

proxy.ClientCredentials.Windows.AllowedImpersonationLevel =  System.Security.Principal.TokenImpersonationLevel.Impersonation;

Didn't make a difference in my case.

However, using this binding worked:

      <security mode="TransportWithMessageCredential">
        <transport clientCredentialType="Windows" />
        <message clientCredentialType="UserName" />
      </security>        

A naive approach could look like this:

#include <map>
#include <sstream>
#include <stdexcept>
#include <string>

std::map<std::string, std::string> options; // global?

void parse(std::istream & cfgfile)
{
    for (std::string line; std::getline(cfgfile, line); )
    {
        std::istringstream iss(line);
        std::string id, eq, val;

        bool error = false;

        if (!(iss >> id))
        {
            error = true;
        }
        else if (id[0] == '#')
        {
            continue;
        }
        else if (!(iss >> eq >> val >> std::ws) || eq != "=" || iss.get() != EOF)
        {
            error = true;
        }

        if (error)
        {
            // do something appropriate: throw, skip, warn, etc.
        }
        else
        {
            options[id] = val;
        }
    }
}

Now you can access each option value from the global options map anywhere in your program. If you want castability, you could make the mapped type a boost::variant.

str1 = "test123.00";
str2 = "yes50.00";
intStr1 = str1.replace(/[A-Za-z$-]/g, "");
intStr2 = str2.replace(/[A-Za-z$-]/g, "");
total = parseInt(intStr1)+parseInt(intStr2);

alert(total);

working Jsfiddle

I would like to propose a version, which seems to be more robust, since I ran into a lot of problems using quantile() in the breaks option cut() on my dataset. I am using the ntile function of plyr, but it also works with ecdf as input.

temp[, `:=`(quartile = .bincode(x = ntile(value, 100), breaks = seq(0,100,25), right = TRUE, include.lowest = TRUE)
            decile = .bincode(x = ntile(value, 100), breaks = seq(0,100,10), right = TRUE, include.lowest = TRUE)
)]

temp[, `:=`(quartile = .bincode(x = ecdf(value)(value), breaks = seq(0,1,0.25), right = TRUE, include.lowest = TRUE)
            decile = .bincode(x = ecdf(value)(value), breaks = seq(0,1,0.1), right = TRUE, include.lowest = TRUE)
)]

Is that correct?

Ensure the browser and editor are using UTF-8 encoding instead of ISO-8859-1/Windows-1252.

Or use ’.

There are a lot of options for regular expressions you could use to accomplish this. One example that will perform well is:

str.replace( /\s\s+/g, ' ' )

See this question for a full discussion on this exact problem: Regex to replace multiple spaces with a single space

What I do is say in the Terminal:

$ xcrun swift -version

Output for Xcode 6.3.2 is:

Apple Swift version 1.2 (swiftlang-602.0.53.1 clang-602.0.53)

Of course that assumes that your xcrun is pointing at your copy of Xcode correctly. If, like me, you're juggling several versions of Xcode, that can be a worry! To make sure that it is, say

$ xcrun --find swift

and look at the path to Xcode that it shows you. For example:

/Applications/Xcode.app/...

If that's your Xcode, then the output from -version is accurate. If you need to repoint xcrun, use the Command Line Tools pop-up menu in Xcode's Locations preference pane.

I tried fs-extra and copy-dir to copy-folder-recursively. but I want it to

1. work normally (copy-dir throws an unreasonable error)
2. provide two arguments in filter: filepath and filetype (fs-extra does't tell filetype)
3. have a dir-to-subdir check and a dir-to-file check

So I wrote my own:

// Node.js module for Node.js 8.6+
var path = require("path");
var fs = require("fs");

function copyDirSync(src, dest, options) {
  var srcPath = path.resolve(src);
  var destPath = path.resolve(dest);
  if(path.relative(srcPath, destPath).charAt(0) != ".")
    throw new Error("dest path must be out of src path");
  var settings = Object.assign(Object.create(copyDirSync.options), options);
  copyDirSync0(srcPath, destPath, settings);
  function copyDirSync0(srcPath, destPath, settings) {
    var files = fs.readdirSync(srcPath);
    if (!fs.existsSync(destPath)) {
      fs.mkdirSync(destPath);
    }else if(!fs.lstatSync(destPath).isDirectory()) {
      if(settings.overwrite)
        throw new Error(`Cannot overwrite non-directory '${destPath}' with directory '${srcPath}'.`);
      return;
    }
    files.forEach(function(filename) {
      var childSrcPath = path.join(srcPath, filename);
      var childDestPath = path.join(destPath, filename);
      var type = fs.lstatSync(childSrcPath).isDirectory() ? "directory" : "file";
      if(!settings.filter(childSrcPath, type))
        return;
      if (type == "directory") {
        copyDirSync0(childSrcPath, childDestPath, settings);
      } else {
        fs.copyFileSync(childSrcPath, childDestPath, settings.overwrite ? 0 : fs.constants.COPYFILE_EXCL);
        if(!settings.preserveFileDate)
          fs.futimesSync(childDestPath, Date.now(), Date.now());
      }
    });
  }
}
copyDirSync.options = {
  overwrite: true,
  preserveFileDate: true,
  filter: function(filepath, type) {
    return true;
  }
};

And a similar function, mkdirs, which is an alternative to mkdirp:

function mkdirsSync(dest) {
  var destPath = path.resolve(dest);
  mkdirsSync0(destPath);
  function mkdirsSync0(destPath) {
    var parentPath = path.dirname(destPath);
    if(parentPath == destPath)
      throw new Error(`cannot mkdir ${destPath}, invalid root`);
    if (!fs.existsSync(destPath)) {
      mkdirsSync0(parentPath);
      fs.mkdirSync(destPath);
    }else if(!fs.lstatSync(destPath).isDirectory()) {
      throw new Error(`cannot mkdir ${destPath}, a file already exists there`);
    }
  }
}

read -p "Are you sure? " -n 1 -r
echo    # (optional) move to a new line
if [[ $REPLY =~ ^[Yy]$ ]]
then
    # do dangerous stuff
fi

I incorporated levislevis85's suggestion (thanks!) and added the -n option to read to accept one character without the need to press Enter. You can use one or both of these.

Also, the negated form might look like this:

read -p "Are you sure? " -n 1 -r
echo    # (optional) move to a new line
if [[ ! $REPLY =~ ^[Yy]$ ]]
then
    [[ "$0" = "$BASH_SOURCE" ]] && exit 1 || return 1 # handle exits from shell or function but don't exit interactive shell
fi

However, as pointed out by Erich, under some circumstances such as a syntax error caused by the script being run in the wrong shell, the negated form could allow the script to continue to the "dangerous stuff". The failure mode should favor the safest outcome so only the first, non-negated if should be used.

Explanation:

The read command outputs the prompt (-p "prompt") then accepts one character (-n 1) and accepts backslashes literally (-r) (otherwise read would see the backslash as an escape and wait for a second character). The default variable for read to store the result in is $REPLY if you don't supply a name like this: read -p "my prompt" -n 1 -r my_var

The if statement uses a regular expression to check if the character in $REPLY matches (=~) an upper or lower case "Y". The regular expression used here says "a string starting (^) and consisting solely of one of a list of characters in a bracket expression ([Yy]) and ending ($)". The anchors (^ and $) prevent matching longer strings. In this case they help reinforce the one-character limit set in the read command.

The negated form uses the logical "not" operator (!) to match (=~) any character that is not "Y" or "y". An alternative way to express this is less readable and doesn't as clearly express the intent in my opinion in this instance. However, this is what it would look like: if [[ $REPLY =~ ^[^Yy]$ ]]

Use the Application Verifier (AppVerifier) tool from Microsoft.

In my case I need to simulate memory no longer being available so I did the following in the tool:

1. Added my application
2. Unchecked Basic
3. Checked Low Resource Simulation
   • Changed TimeOut to 120000 - my application will run normally for 2 minutes before anything goes into effect.
   • Changed HeapAlloc to 100 - 100% chance of heap allocation error
   • Set Stacks to true - the stack will not be able to grow any larger
4. Save
5. Start my application

After 2 minutes my program could no longer allocate new memory and I was able to see how everything was handled.

The idea that you hope to achieve can be made possible if you tweak the requirement a little bit

The below code is possible if your runtime supports the ES6 specification.

More about async functions

async function myAsynchronousCall(param1) {
    // logic for myAsynchronous call
    return d;
}

function doSomething() {

  var data = await myAsynchronousCall(param1); //'blocks' here until the async call is finished
  return data;
}

return b(); calls the function b(), and returns its result.

return b; returns a reference to the function b, which you can store in a variable to call later.

You can wild-card inline using the following technique (which is the way in which @Andomar's solution is saved in the .csproj)

<Compile Include="..\MySisterProject\**\*.cs">
  <Link>_Inlined\MySisterProject\%(RecursiveDir)%(Filename)%(Extension)</Link>
</Compile>

Put in:

    <Visible>false</Visible>

If you want to hide the files and/or prevent the wild-card include being expanded if you add or remove an item from a 'virtual existing item' folder like MySisterProject above.

Sure, here is an example (standard HTML boilerplate omitted):

<svg id="svg1" xmlns="http://www.w3.org/2000/svg" style="width: 3.5in; height: 1in">_x000D_
  <circle id="circle1" r="30" cx="34" cy="34" _x000D_
            style="fill: red; stroke: blue; stroke-width: 2"/>_x000D_
  </svg>_x000D_
<button onclick="circle1.style.fill='yellow';">Click to change to yellow</button>

Although I am very late to this but after seeing some legitimate questions for those who wanted to use INSERT-SELECT query with GROUP BY clause, I came up with the work around for this.

Taking further the answer of Marcus Adams and accounting GROUP BY in it, this is how I would solve the problem by using Subqueries in the FROM Clause

INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, 
                inact, inadur, inadist, 
                smlct, smldur, smldist, 
                larct, lardur, lardist, 
                emptyct, emptydur)
SELECT sb.id, uid, sb.location, sb.animal, sb.starttime, sb.endtime, sb.entct, 
       sb.inact, sb.inadur, sb.inadist, 
       sb.smlct, sb.smldur, sb.smldist, 
       sb.larct, sb.lardur, sb.lardist, 
       sb.emptyct, sb.emptydur
FROM
(SELECT id, uid, location, animal, starttime, endtime, entct, 
       inact, inadur, inadist, 
       smlct, smldur, smldist, 
       larct, lardur, lardist, 
       emptyct, emptydur 
FROM tmp WHERE uid=x
GROUP BY location) as sb
ON DUPLICATE KEY UPDATE entct=sb.entct, inact=sb.inact, ...

You can try the regex here to filter out the columns starting with "foo"

df.filter(regex='^foo*')

If you need to have the string foo in your column then

df.filter(regex='foo*')

would be appropriate.

For the next step, you can use

df[df.filter(regex='^foo*').values==1]

to filter out the rows where one of the values of 'foo*' column is 1.

In python3, __init__.py is no longer necessary. If the current directory of the console is the directory where the python script is located, everything works fine with

import user

However, this won't work if called from a different directory, which does not contain user.py.
In that case, use

from . import user

This works even if you want to import the whole file instead of just a class from there.

A terser way, either with rev :

x[!(!duplicated(x) & rev(!duplicated(rev(x))))]

... rather than fromLast:

x[!(!duplicated(x) & !duplicated(x, fromLast = TRUE))]

... and as a helper function to provide either logical vector or elements from original vector :

duplicates <- function(x, as.bool = FALSE) {
    is.dup <- !(!duplicated(x) & rev(!duplicated(rev(x))))
    if (as.bool) { is.dup } else { x[is.dup] }
}

Treating vectors as data frames to pass to table is handy but can get difficult to read, and the data.table solution is fine but I'd prefer base R solutions for dealing with simple vectors like IDs.

Stateless here means that state or meta data of request is not maintained on server side. By maintaining each request or user's state on server, it would lead to performance bottlenecks. Server is just requested with required attributes to perform any specific operations.

Coming to managing sessions, or giving customize experience to users, it requires to maintain some meta data or state of user likely user's preferences, past request history. This can be done by maintaining cookies, hidden attributes or into session object.

This can maintain or keep track of user's state in the application.

Hope this helps!

If the array keys in your PHP array are not consecutive numbers, json_encode() must make the other construct an object since JavaScript arrays are always consecutively numerically indexed.

Use array_values() on the outer structure in PHP to discard the original array keys and replace them with zero-based consecutive numbering:

Example:

// Non-consecutive 3number keys are OK for PHP
// but not for a JavaScript array
$array = array(
  2 => array("Afghanistan", 32, 13),
  4 => array("Albania", 32, 12)
);

// array_values() removes the original keys and replaces
// with plain consecutive numbers
$out = array_values($array);
json_encode($out);
// [["Afghanistan", 32, 13], ["Albania", 32, 12]]

You've forgot to define an onclick attribute to do something when the button is clicked, so nothing happening is the correct execution, see below;

<input type="button" id="moreFields" onclick="moreFields()" value="Give me more fields!"  />
                                     ----------------------

I think random.choice() is a better option.

import numpy as np

mylist = [13,23,14,52,6,23]

np.random.choice(mylist, 3, replace=False)

the function returns an array of 3 randomly chosen values from the list

import sys
import timeit

start = timeit.default_timer()

#do some nice things...

stop = timeit.default_timer()
total_time = stop - start

# output running time in a nice format.
mins, secs = divmod(total_time, 60)
hours, mins = divmod(mins, 60)

sys.stdout.write("Total running time: %d:%d:%d.\n" % (hours, mins, secs))

Not direct answer to your question, but I've been quite frustrated myself trying find and update all of the tnsnames files, as I had several oracle installs: Client, BI tools, OWB, etc, each of which had its own oracle home. I ended up creating a utility called TNSNamesSync that will update all of the tnsnames in all of the oracle homes. It's under the MIT license, free to use here https://github.com/artybug/TNSNamesSync/releases

The docs are here: https://github.com/artchik/TNSNamesSync/blob/master/README.md

This is for Windows only, though.

Using lodash:

function csvToJson(csv) {
  const content = csv.split('\n');
  const header = content[0].split(',');
  return _.tail(content).map((row) => {
    return _.zipObject(header, row.split(','));
  });
}

The recent versions of XAMPP for Windows runs PHP 7.x which are NOT compatible with mbcrypt. If you have a package like Laravel that requires mbcrypt, you will need to install an older version of XAMPP. OR, you can run XAMPP with multiple versions of PHP by downloading a PHP package from Windows.PHP.net, installing it in your XAMPP folder, and configuring php.ini and httpd.conf to use the correct version of PHP for your site.

You can create a setTimeout loop using recursion:

function timeout() {
    setTimeout(function () {
        // Do Something Here
        // Then recall the parent function to
        // create a recursive loop.
        timeout();
    }, 1000);
}

The problem with setInterval() and setTimeout() is that there is no guarantee your code will run in the specified time. By using setTimeout() and calling it recursively, you're ensuring that all previous operations inside the timeout are complete before the next iteration of the code begins.

There can be one more approach. However it is not as efficient as the one already suggested in answers.

• Create a path vector for the node n1.

• Create a second path vector for the node n2.

• Path vector implying the set nodes from that one would traverse to reach the node in question.

• Compare both path vectors. The index where they mismatch, return the node at that index - 1. This would give the LCA.

Cons for this approach:

Need to traverse the tree twice for calculating the path vectors. Need addtional O(h) space to store path vectors.

However this is easy to implement and understand as well.

Code for calculating the path vector:

private boolean findPathVector (TreeNode treeNode, int key, int pathVector[], int index) {

        if (treeNode == null) {
            return false;
        }

        pathVector [index++] = treeNode.getKey ();

        if (treeNode.getKey () == key) {
            return true;
        }
        if (findPathVector (treeNode.getLeftChild (), key, pathVector, index) || 
            findPathVector (treeNode.getRightChild(), key, pathVector, index)) {

            return true;        
        }

        pathVector [--index] = 0;
        return false;       
    }

You can handle WM_NCPAINT message of TextBox and draw a border on the non-client area of control if the control has focus. You can use any color to draw border:

using System;
using System.Drawing;
using System.Runtime.InteropServices;
using System.Windows.Forms;
public class ExTextBox : TextBox
{
    [DllImport("user32")]
    private static extern IntPtr GetWindowDC(IntPtr hwnd);
    private const int WM_NCPAINT = 0x85;
    protected override void WndProc(ref Message m)
    {
        base.WndProc(ref m);
        if (m.Msg == WM_NCPAINT && this.Focused)
        {
            var dc = GetWindowDC(Handle);
            using (Graphics g = Graphics.FromHdc(dc))
            {
                g.DrawRectangle(Pens.Red, 0, 0, Width - 1, Height - 1);
            }
        }
    }
}

Result

The painting of borders while the control is focused is completely flicker-free:

BorderColor property for TextBox

In the current post I just change the border color on focus. You can also add a BorderColor property to the control. Then you can change border-color based on your requirement at design-time or run-time. I've posted a more completed version of TextBox which has BorderColor property: in the following post:

• BorderColor property for TextBox

In my case setting the referenced object to NULL in my object before the merge o save method solve the problem, in my case the referenced object was catalog, that doesn't need to be saved, because in some cases I don't have it even.

    fisEntryEB.setCatStatesEB(null);

    (fisEntryEB) getSession().merge(fisEntryEB);

There is a major error in the tutorials destined for newbies here: http://developer.android.com/training/basics/actionbar/styling.html

It is major because it is almost impossible to detect cause of error for a newbie.

The error is that this tutorial explicitly states that the tutorial is valid for api level 11 (Android 3.0), while in reality this is only true for the theme Theme.Holo (without further extensions and variants)

But this tutorial uses the the theme Theme.holo.Light.DarkActionBar which is only a valid theme from api level 14 (Android 4.0) and above.

This is only one of many examples on errors found in these tutorials (which are great in other regards). Somebody should correct these errors this weekend because they are really costly and annoying timethieves. If there is a way I can send this info to the Android team, then please tell me and I will do it. Hopefully, however, they read Stackoverflow. (let me suggest: The Android team should consider to put someone newbie to try out all tutorials as a qualification that they are valid).

Another error I (and countless other people) have found is that the appcombat backward compliance module really is not working if you strictly follow the tutorials. Error unknown. I had to give up.

Regarding the error in this thread, here is a quote from the tutorial text with italics on the mismatch:

" For Android 3.0 and higher only

When supporting Android 3.0 and higher only, you can define the action bar's background like this:

    <resources>
        <!-- the theme applied to the application or activity -->
        <style name="CustomActionBarTheme"
        parent="@style/Theme.Holo.Light.DarkActionBar"> 

ERROR1: Only Theme.Holo can be used with Android 3.0. Therefore, remove the "Light.DarkActionBar etc.

ERROR2: @style/Theme.Holo"> will not work. It is necessary to write @android:style/Theme.Holo">in order to indicate that it is a built in Theme that is being referenced. (A bit strange that "built in" is not the default, but needs to be stated?)

The compiler advice for error correction is to define api level 14 as minimum sdk. This is not optimal because it creates incompliance to Andreoid 3.0 (api level 11). Therefore, I use Theme.Holo only and this seems to work fine (a fresh finding, though).

I am using Netbeans with Android support. Works nicely.

Using jQuery, easiest way to get array of keys from object is following:

$.map(obj, function(element,index) {return index})

In your case, it will return this array: ["alfa", "beta"]

You cannot exactly get a list of commands started with nohup but you can see them along with your other processes by using the command ps x. Commands started with nohup will have a question mark in the TTY column.

request.data will be empty if request.headers["Content-Type"] is recognized as form data, which will be parsed into request.form. To get the raw data regardless of content type, use request.get_data().

request.data calls request.get_data(parse_form_data=True), which results in the different behavior for form data.

In Ruby 2.0, you can also use lambdas in case statements, as follows:

is_even = ->(x) { x % 2 == 0 }

case number
when 0 then puts 'zero'
when is_even then puts 'even'
else puts 'odd'
end

You can also create your own comparators easily using a Struct with a custom ===

Moddable = Struct.new(:n) do
  def ===(numeric)
    numeric % n == 0
  end
end

mod4 = Moddable.new(4)
mod3 = Moddable.new(3)

case number
when mod4 then puts 'multiple of 4'
when mod3 then puts 'multiple of 3'
end

(Example taken from "Can procs be used with case statements in Ruby 2.0?".)

Or, with a complete class:

class Vehicle
  def ===(another_vehicle)
    self.number_of_wheels == another_vehicle.number_of_wheels
  end
end

four_wheeler = Vehicle.new 4
two_wheeler = Vehicle.new 2

case vehicle
when two_wheeler
  puts 'two wheeler'
when four_wheeler
  puts 'four wheeler'
end

(Example taken from "How A Ruby Case Statement Works And What You Can Do With It".)

You need to subscribe to the observable and pass a callback that processes emitted values

this.myService.getConfig().subscribe(val => console.log(val));

it would be something like this

sqlplus -s /nolog  <<-!
connect ${ORACLE_UID}/${ORACLE_PWD}@${ORACLE_DB};
whenever sqlerror exit sql.sqlcode;
set pagesize 0;
set linesize 150;
spool <query_output.dat> APPEND
@$<input_query.dat>
spool off;
exit;
!

here

ORACLE_UID=<user name>
ORACLE_PWD=<password>
ORACLE_DB=//<host>:<port>/<DB name>

There are a few things you can try to get this working.

1. Be ABSOLUTELY sure your script is being pulled into the page, one way to check is by using the 'sources' tab in the Chrome Debugger and searching for the file.

2. Be sure that you've included the script after you've included jQuery, as it is most certainly dependant upon that.

Other than that, I checked out the API and you're definitely doing everything right as far as I can see. Best of luck friend!

EDIT: Ensure you close your script tag. There's an answer below that points to that being the solution.

Just try "Incognito" mode in Chrome.

Finally, this helped me to solve my issue.

Please keep your mind, this is not a permanent solution.

You could try this:

        <script type="text/javascript">
         function newWindow(url){
                window.open(url);
            }
        </script>

And call the function

There are a lot of helpful solutions out there, but there is no simplified way with extension. Here is the code to solve the issue with an extension:

extension UIImage {

    var getWidth: CGFloat {
        get {
            let width = self.size.width
            return width
        }
    }

    var getHeight: CGFloat {
        get {
            let height = self.size.height
            return height
        }
    }
}

If you wish to execute a script file from the git bash prompt on Windows, just precede the script file with sh

sh my_awesome_script.sh

You can use

display: flex;

CSS property, as mentioned before by @Ayan, but I've created a working example: https://jsfiddle.net/d2kjxd51/

1. As per https://msdn.microsoft.com/en-us/library/ms180065.aspx, "DBCC USEROPTIONS reports an isolation level of 'read committed snapshot' when the database option READ_COMMITTED_SNAPSHOT is set to ON and the transaction isolation level is set to 'read committed'. The actual isolation level is read committed."

2. Also in SQL Server Management Studio, in database properties under Options->Miscellaneous there is "Is Read Committed Snapshot On" option status

yes you need to use a having clause after the Group by clause , as the where is just to filter the data on simple parameters , but group by followed by a Having statement is the idea to group the data and filter it on basis of some aggregate function......

Suppose I have a model User

1. User.find(id)

Returns a row where primary key = id. The return type will be User object.

2. User.find_by(email:"[email protected]")

Returns first row with matching attribute or email in this case. Return type will be User object again.

Note :- User.find_by(email: "[email protected]") is similar to User.find_by_email("[email protected]")

3. User.where(project_id:1)

Returns all users in users table where attribute matches.

Here return type will be ActiveRecord::Relation object. ActiveRecord::Relation class includes Ruby's Enumerable module so you can use it's object like an array and traverse on it.

As stated here this can happen when using the Gradle Tools v1.1.0. After updating to v1.1.3, this has not happened anymore.
