You are actually getting the correct value out.

The way your x86 (compatible) processor stores data like this, is in Little Endian order, meaning that, the MSB is last in your output.

So, given your output:

10101010

the last two hex values 10 are the Most Significant Byte (2 hex digits = 1 byte = 8 bits (for (possibly unnecessary) clarification).

So, by reversing the memory storage order of the bytes, your value is actually: 01010101.

Hope that clears it up!

in our use we have to capture with host x.x.x.x. or (vlan and host x.x.x.x)

anything less will not capture? I am not sure why but that is the way it works!

None of the previous solutions worked for me in Xamarin Android. I was able to get the right drawable click listener working using the following:

Create the following OnEditTextTouch event listener:

  private void OnEditTextTouch(object sender, View.TouchEventArgs e)
    {
        var rightDrawable = _autoCompleteTextViewSearch.GetCompoundDrawables()[2];

        if (rightDrawable == null || e.Event.Action != MotionEventActions.Up)
        {
            e.Handled = false;

            return;
        }

        if (e.Event.GetX() >= _autoCompleteTextViewSearch.Width - _autoCompleteTextViewSearch.TotalPaddingRight)
        {
            // Invoke your desired action here.

            e.Handled = true;
        }

        // Forward the event along to the sender (crucial for default behaviour)
        (sender as AutoCompleteTextView)?.OnTouchEvent(e.Event);
    }

Subscribe to the Touch event:

_autoCompleteTextViewSearch.Touch += OnEditTextTouch;

The code could be cleaner, but this seems to do the trick for different locales.

import java.math.BigDecimal;
import java.text.DecimalFormatSymbols;
import java.util.Locale;


public class Main
{
    public static void main(String[] args)
    {
        final BigDecimal numberA;
        final BigDecimal numberB;

        numberA = stringToBigDecimal("1,000,000,000.999999999999999", Locale.CANADA);
        numberB = stringToBigDecimal("1.000.000.000,999999999999999", Locale.GERMANY);
        System.out.println(numberA);
        System.out.println(numberB);
    }

    private static BigDecimal stringToBigDecimal(final String formattedString,
                                                 final Locale locale)
    {
        final DecimalFormatSymbols symbols;
        final char                 groupSeparatorChar;
        final String               groupSeparator;
        final char                 decimalSeparatorChar;
        final String               decimalSeparator;
        String                     fixedString;
        final BigDecimal           number;

        symbols              = new DecimalFormatSymbols(locale);
        groupSeparatorChar   = symbols.getGroupingSeparator();
        decimalSeparatorChar = symbols.getDecimalSeparator();

        if(groupSeparatorChar == '.')
        {
            groupSeparator = "\\" + groupSeparatorChar;
        }
        else
        {
            groupSeparator = Character.toString(groupSeparatorChar);
        }

        if(decimalSeparatorChar == '.')
        {
            decimalSeparator = "\\" + decimalSeparatorChar;
        }
        else
        {
            decimalSeparator = Character.toString(decimalSeparatorChar);
        }

        fixedString = formattedString.replaceAll(groupSeparator , "");
        fixedString = fixedString.replaceAll(decimalSeparator , ".");
        number      = new BigDecimal(fixedString);

        return (number);
    }
}

I know this an old subject but in case any finds this like myself:

I used the following code when i needed my directive to update values when the "parent scope" updated. Please by all means correct me if am doing something wrong as i am still learning angular, but this did what i needed;

directive:

directive('dateRangePrint', function(){
    return {
        restrict: 'E',
        scope:{
        //still using the single dir binding
            From: '@rangeFrom',
            To: '@rangeTo',
            format: '@format'
        },
        controller: function($scope, $element){

            $scope.viewFrom = function(){
                    return formatDate($scope.From, $scope.format);
                }

            $scope.viewTo = function(){
                    return formatDate($scope.To, $scope.format);
                }

            function formatDate(date, format){
                format = format || 'DD-MM-YYYY';

                //do stuff to date...

                return date.format(format);
            }

        },
        replace: true,
        // note the parenthesis after scope var
        template: '<span>{{ viewFrom() }} - {{ viewTo() }}</span>'
    }
})

This will let you read, write and create the file if it don't exist:

f = open('filename.txt','a+')
f = open('filename.txt','r+')

Often used commands:

f.readline() #Read next line
f.seek(0) #Jump to beginning
f.read(0) #Read all file
f.write('test text') #Write 'test text' to file
f.close() #Close file

MSSQL have its own database management tool called as "MSSQL Server Management Studio (SSMS)". Here are steps to reset SA password using SSMS :

1] Open SSMS management console, it will prompt for authentication details,

Select Server Type : "Database Engine", Server name : IP / hostname of your MSSQL server Authentication : Windows Authentication

Once you select Authentication type as "Windows Authentication", the user name and password fields will be grayed out and it will allow you to login SQL server without entering login details. Windows Authentication is possible only when you are logged on same server in RDP on which SQL service is present.

2] once you are in, under "Object Explorer" expand Security and then Logins 3] locate and right click on user SA and select Properties 4] under General section enter desired password in front of "Password:" and "Confirm Password:" 5] hit OK at bottom.

This is the easiest and secure way to reset SA password instead of using any third party non secure tools

Here, I summarize a few ways which may return different results to your question, so be careful:

# First assign your "id"s to an R object.
# Here's a hypothetical example:
id <- c("a","b","b","c","c","c","d","d","d","d")

#To return ALL MINUS ONE duplicated values:
id[duplicated(id)]
## [1] "b" "c" "c" "d" "d" "d"

#To return ALL duplicated values by specifying fromLast argument:
id[duplicated(id) | duplicated(id, fromLast=TRUE)]
## [1] "b" "b" "c" "c" "c" "d" "d" "d" "d"

#Yet another way to return ALL duplicated values, using %in% operator:
id[ id %in% id[duplicated(id)] ]
## [1] "b" "b" "c" "c" "c" "d" "d" "d" "d"

Hope these help. Good luck.

can also Use parameterized each with index and the element.

$('#selectIntegrationConf').find('option').each(function(index,element){
 console.log(index);
 console.log(element.value);
 console.log(element.text);
 });

// this will also work

$('#selectIntegrationConf option').each(function(index,element){
 console.log(index);
 console.log(element.value);
 console.log(element.text);
 });

Throwing an exception is how getSingleResult() indicates it can't be found. Personally I can't stand this kind of API. It forces spurious exception handling for no real benefit. You just have to wrap the code in a try-catch block.

Alternatively you can query for a list and see if its empty. That doesn't throw an exception. Actually since you're not doing a primary key lookup technically there could be multiple results (even if one, both or the combination of your foreign keys or constraints makes this impossible in practice) so this is probably the more appropriate solution.

Another option if you are using Guava Collections is Ints.indexOf

// Perfect storm:
final int needle = 42;
final int[] haystack = [1, 2, 3, 42];

// Spoiler alert: index == 3
final int index = Ints.indexOf(haystack, needle);

This is a great choice when space, time and code reuse are at a premium. It is also very terse.

Edit php.ini

Find this line:

max_execution_time

Change its value to 300:

max_execution_time = 300

300 means 5 minutes of execution time for the http request.

It far easier to use the scripting runtime which is installed by default on Windows

Just go project Reference and check Microsoft Scripting Runtime and click OK.

Then you can use this code which is way better than the default file commands

Dim FSO As FileSystemObject
Dim TS As TextStream
Dim TempS As String
Dim Final As String
Set FSO = New FileSystemObject
Set TS = FSO.OpenTextFile("C:\Clients\Converter\Clockings.mis", ForReading)
'Use this for reading everything in one shot
Final = TS.ReadAll
'OR use this if you need to process each line
Do Until TS.AtEndOfStream
    TempS = TS.ReadLine
    Final = Final & TempS & vbCrLf
Loop
TS.Close

Set TS = FSO.OpenTextFile("C:\Clients\Converter\2.txt", ForWriting, True)
    TS.Write Final
TS.Close
Set TS = Nothing
Set FSO = Nothing

As for what is wrong with your original code here you are reading each line of the text file.

Input #iFileNo, sFileText

Then here you write it out

Write #iFileNo, sFileText

sFileText is a string variable so what is happening is that each time you read, you just replace the content of sFileText with the content of the line you just read.

So when you go to write it out, all you are writing is the last line you read, which is probably a blank line.

Dim sFileText As String
Dim sFinal as String
Dim iFileNo As Integer
iFileNo = FreeFile
Open "C:\Clients\Converter\Clockings.mis" For Input As #iFileNo
Do While Not EOF(iFileNo)
  Input #iFileNo, sFileText
sFinal = sFinal & sFileText & vbCRLF
Loop
Close #iFileNo

iFileNo = FreeFile 'Don't assume the last file number is free to use
Open "C:\Clients\Converter\2.txt" For Output As #iFileNo
Write #iFileNo, sFinal
Close #iFileNo

Note you don't need to do a loop to write. sFinal contains the complete text of the File ready to be written at one shot. Note that input reads a LINE at a time so each line appended to sFinal needs to have a CR and LF appended at the end to be written out correctly on a MS Windows system. Other operating system may just need a LF (Chr$(10)).

If you need to process the incoming data then you need to do something like this.

Dim sFileText As String
Dim sFinal as String
Dim vTemp as Variant
Dim iFileNo As Integer
Dim C as Collection
Dim R as Collection
Dim I as Long
Set C = New Collection
Set R = New Collection

iFileNo = FreeFile
Open "C:\Clients\Converter\Clockings.mis" For Input As #iFileNo
Do While Not EOF(iFileNo)
  Input #iFileNo, sFileText
  C.Add sFileText
Loop
Close #iFileNo

For Each vTemp in C
     Process vTemp
Next sTemp

iFileNo = FreeFile
Open "C:\Clients\Converter\2.txt" For Output As #iFileNo
For Each vTemp in R
   Write #iFileNo, vTemp & vbCRLF
Next sTemp
Close #iFileNo

I wrote a .gitconfig [alias] for performing a "sparse checkout". Check it out (no pun intended):

On Windows run in cmd.exe

git config --global alias.sparse-checkout "!f(){ [ $# -eq 2 ] && L=${1##*/} L=${L%.git} || L=$2; mkdir -p \"$L/.git/info\" && cd \"$L\" && git init --template= && git remote add origin \"$1\" && git config core.sparseCheckout 1; [ $# -eq 2 ] && echo \"$2\" >> .git/info/sparse-checkout || { shift 2; for i; do echo $i >> .git/info/sparse-checkout; done }; git pull --depth 1 origin master;};f"

Otherwise:

git config --global alias.sparse-checkout '!f(){ [ $# -eq 2 ] && L=${1##*/} L=${L%.git} || L=$2; mkdir -p "$L/.git/info" && cd "$L" && git init --template= && git remote add origin "$1" && git config core.sparseCheckout 1; [ $# -eq 2 ] && echo "$2" >> .git/info/sparse-checkout || { shift 2; for i; do echo $i >> .git/info/sparse-checkout; done }; git pull --depth 1 origin master;};f'

Usage:

# Makes a directory ForStackExchange with Plug checked out
git sparse-checkout https://github.com/YenForYang/ForStackExchange Plug

# To do more than 1 directory, you have to specify the local directory:
git sparse-checkout https://github.com/YenForYang/ForStackExchange ForStackExchange Plug Folder

The git config commands are 'minified' for convenience and storage, but here is the alias expanded:

# Note the --template= is for disabling templates.
# Feel free to remove it if you don't have issues with them (like I did)
# `mkdir` makes the .git/info directory ahead of time, as I've found it missing sometimes for some reason
f(){
    [ "$#" -eq 2 ] && L="${1##*/}" L=${L%.git} || L=$2;
    mkdir -p "$L/.git/info"
        && cd "$L"
        && git init --template=
        && git remote add origin "$1"
        && git config core.sparseCheckout 1;
    [ "$#" -eq 2 ]
        && echo "$2" >> .git/info/sparse-checkout
        || {
            shift 2;
            for i; do
                echo $i >> .git/info/sparse-checkout;
            done
        };
    git pull --depth 1 origin master;
};
f

Better analogy than the telephone call: Ordering products via postal mail from a mail-order service. The WSDL document is like the instructions that explain how to create the kind of order forms that the service provider will accept. A SOAP message is like an envelope with a standard design (size, shape, construction) that every post office around the world knows how to handle. You put your order form into such an envelope. The network (e.g. the internet) is the postal service. You put your envelope into the mail. The employees of the postal service do not look inside the envelope. The payload XML is the order form that you have enclosed in the envelope. After the post office delivers the envelope, the web service provider opens the envelope and processes the order form. If you have created and filled out the form correctly, they will mail the product that you ordered back to you.

Annoying error. I solved it by plugging the cable directly into the iPad. For some reason the process would never finish if I had the iPad in Apple's pass-through stand.

For simple dockerized projects, I could not really see any existing answer fit.

So I wrote a very barebones solution without the need of external libraries or triggers, which runs on its own. No external os-cron needed, should work in every environment.

It works by adding a middleware: middleware.py

import threading

def should_run(name, seconds_interval):
    from application.models import CronJob
    from django.utils.timezone import now

    try:
        c = CronJob.objects.get(name=name)
    except CronJob.DoesNotExist:
        CronJob(name=name, last_ran=now()).save()
        return True

    if (now() - c.last_ran).total_seconds() >= seconds_interval:
        c.last_ran = now()
        c.save()
        return True

    return False


class CronTask:
    def __init__(self, name, seconds_interval, function):
        self.name = name
        self.seconds_interval = seconds_interval
        self.function = function


def cron_worker(*_):
    if not should_run("main", 60):
        return

    # customize this part:
    from application.models import Event
    tasks = [
        CronTask("events", 60 * 30, Event.clean_stale_objects),
        # ...
    ]

    for task in tasks:
        if should_run(task.name, task.seconds_interval):
            task.function()


def cron_middleware(get_response):

    def middleware(request):
        response = get_response(request)
        threading.Thread(target=cron_worker).start()
        return response

    return middleware

models/cron.py:

from django.db import models


class CronJob(models.Model):
    name = models.CharField(max_length=10, primary_key=True)
    last_ran = models.DateTimeField()

settings.py:

MIDDLEWARE = [
    ...
    'application.middleware.cron_middleware',
    ...
]

This one here:

s = raw_input()
a=len(s)
for i in xrange(0, a):
    for j in xrange(0, a):
        if j >= i:
            if len(s[i:j+1]) > 0:
                sub_strings.append(s[i:j+1])

seems to be very inefficient and expensive for large strings.

Better do

for i in xrange(0, a):
    for j in xrange(i, a): # ensures that j >= i, no test required
        part = buffer(s, i, j+1-i) # don't duplicate data
        if len(part) > 0:
            sub_Strings.append(part)

A buffer object keeps a reference to the original string and start and length attributes. This way, no unnecessary duplication of data occurs.

A string of length l has l*l/2 sub strings of average length l/2, so the memory consumption would roughly be l*l*l/4. With a buffer, it is much smaller.

Note that buffer() only exists in 2.x. 3.x has memoryview(), which is utilized slightly different.

Even better would be to compute the indexes and cut out the substring on demand.

I had a lot of problems with this remote helper issue. I ensured that I had installed all the expat, curl etc. but finally resolved it by updating gcc after finding that version 4.4.4 was duff. Just did a yum update and recompiled with 4.4.6.

I had this error today on a nested MVC application running as virtual folder in onother MVC application. In my case the InnerException was more informative than the main one. It was stating:

- The entry 'DbContextMain' has already been added. (C:\inetpub\...\web.config line x)

After fixing the duplicate connection strings in the nested apps everything worked fine.

$.each() works for objects and arrays both:

var data = { "programs": [ { "name":"zonealarm", "price":"500" }, { "name":"kaspersky", "price":"200" } ] };

$.each(data.programs, function (i) {
    $.each(data.programs[i], function (key, val) {
        alert(key + val);
    });
});

...and since you will get the current array element as second argument:

$.each(data.programs, function (i, currProgram) {
    $.each(currProgram, function (key, val) {
        alert(key + val);
    });
});

it may be very old post, but I would like to share my experience. I had the same issue when I used Pycharm and I installed the package from Project Interpreter page in the Project Settings/Preferences... That fixed the issue, please check below link: https://www.jetbrains.com/help/pycharm/installing-uninstalling-and-upgrading-packages.html?_ga=2.41088674.1813230270.1594526819-1842497340.1594080707

If you have a SharedPreferenceActivity by which you have saved your values

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
String imgSett = prefs.getString(keyChannel, "");

if the value is saved in a SharedPreference in an Activity then this is the correct way to saving it.

SharedPreferences shared = getSharedPreferences(PREF_NAME, MODE_PRIVATE);
SharedPreferences.Editor editor = shared.edit();
editor.putString(keyChannel, email);
editor.commit();// commit is important here.

and this is how you can retrieve the values.

SharedPreferences shared = getSharedPreferences(PREF_NAME, MODE_PRIVATE);
String channel = (shared.getString(keyChannel, ""));

Also be aware that you can do so in a non-Activity class too but the only condition is that you need to pass the context of the Activity. use this context in to get the SharedPreferences.

mContext.getSharedPreferences(PREF_NAME, MODE_PRIVATE);

First of all, go to String.xml file

you can add any HTML attributes like , italic or bold or underline here.

    <resources>
        <string name="your_string_here">This is an <u>underline</u>.</string>
    </resources>

Here is a quick comment for people who don't need a div but just a blockelement. In HTML5 <fieldset disabled="disabled"></fieldset> got the disabled attribute. Every form element in a disabled fieldset is disabled.

Duck Typing is not Type Hinting!

Basically in order to use "duck typing" you will not target a specific type but rather a wider range of subtypes (not talking about inheritance, when I mean subtypes I mean "things" that fit within the same profiles) by using a common interface.

You can imagine a system that stores information. In order to write/read information you need some sort of storage and information.

Types of storage may be: file, database, session etc.

The interface will let you know the available options (methods) regardless of the storage type, meaning that at this point nothing is implemented! In another words the Interface doesn't know nothing about how to store information.

Every storage system must know the existence of the interface by implementing it's very same methods.

interface StorageInterface
{
   public function write(string $key, array $value): bool;
   public function read(string $key): array;
}


class File implements StorageInterface
{
    public function read(string $key): array {
        //reading from a file
    }

    public function write(string $key, array $value): bool {
         //writing in a file implementation
    }
}


class Session implements StorageInterface
{
    public function read(string $key): array {
        //reading from a session
    }

    public function write(string $key, array $value): bool {
         //writing in a session implementation
    }
}


class Storage implements StorageInterface
{
    private $_storage = null;

    function __construct(StorageInterface $storage) {
        $this->_storage = $storage;
    }

    public function read(string $key): array {
        return $this->_storage->read($key);
    }

    public function write(string $key, array $value): bool {
        return ($this->_storage->write($key, $value)) ? true : false;
    }
}

So now, every time you need to write/read information:

$file = new Storage(new File());
$file->write('filename', ['information'] );
echo $file->read('filename');

$session = new Storage(new Session());
$session->write('filename', ['information'] );
echo $session->read('filename');

In this example you end up using Duck Typing in Storage constructor:

function __construct(StorageInterface $storage) ...

Hope it helped ;)

This is Simple and best calculation for me and may be for you.

       try {
            /// String CurrDate=  "10/6/2013";
            /// String PrvvDate=  "10/7/2013";
            Date date1 = null;
            Date date2 = null;
            SimpleDateFormat df = new SimpleDateFormat("M/dd/yyyy");
            date1 = df.parse(CurrDate);
            date2 = df.parse(PrvvDate);
            long diff = Math.abs(date1.getTime() - date2.getTime());
            long diffDays = diff / (24 * 60 * 60 * 1000);


            System.out.println(diffDays);

        } catch (Exception e1) {
            System.out.println("exception " + e1);
        }

You can use it like this:

$(document).ready(function(){

    setTimeout("swapImages()",1000);

    function swapImages(){

        var active = $('.active'); 
        var next = ($('.active').next().length > 0) ? $('.active').next() : $('#siteNewsHead img:first');

        active.removeClass('active');
        next.addClass('active');
        setTimeout("swapImages()",1000);
}

});

From 6.11. Boolean operations:

In the context of Boolean operations, and also when expressions are used by control flow statements, the following values are interpreted as false: False, None, numeric zero of all types, and empty strings and containers (including strings, tuples, lists, dictionaries, sets and frozensets). All other values are interpreted as true.

The key phrasing here that I think you are misunderstanding is "interpreted as false" or "interpreted as true". This does not mean that any of those values are identical to True or False, or even equal to True or False.

The expression '/bla/bla/bla' will be treated as true where a Boolean expression is expected (like in an if statement), but the expressions '/bla/bla/bla' is True and '/bla/bla/bla' == True will evaluate to False for the reasons in Ignacio's answer.

This will show you clues about why the linker doesn't want the installed library:

LD_DEBUG=all make ...

I had the same problem in a different context: my system /lib/libz.so.1 had unsatisfied dependencies on libc because I was trying to relink on a different version of the OS.

Here's what I did to fix this:

1) Create a new project

2) open the gradle-wrapper.properties file and copy the distributionUrl to your project e.g.:

distributionUrl=https\://services.gradle.org/distributions/gradle-3.2-all.zip

3) open the build.gradle (Project) and copy the gradle dependency to your project e.g.:

classpath 'com.android.tools.build:gradle:2.3.0-beta1'

4) File --> Invalidate Caches / Restart (I think a re-sync may have sufficed, but didn't try it)

5) Delete that project you made (optional)

Look, this is a silly way to do things, but Android Studio is free so who am I to complain...

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

If you just want to get the path to a certain action, use UrlHelper:

UrlHelper u = new UrlHelper(this.ControllerContext.RequestContext);
string url = u.Action("About", "Home", null);

if you want to create a hyperlink:

string link = HtmlHelper.GenerateLink(this.ControllerContext.RequestContext, System.Web.Routing.RouteTable.Routes, "My link", "Root", "About", "Home", null, null);

Intellisense will give you the meaning of each of the parameters.

Update from comments: controller already has a UrlHelper:

string url = this.Url.Action("About", "Home", null); 

Just use the change directory (cd) command.

cd d:\windows\movie

Apache needs to be configured to recognize index.php as an index file.

The simplest way to accomplish this..

1. Create a .htaccess file in your web root.

2. Add the line...

DirectoryIndex index.php

Here is a resource regarding the matter...
http://www.twsc.biz/twsc_hosting_htaccess.php

Edit: I'm assuming apache is configured to allow .htaccess files. If it isn't, you'll have to modify the setting in apache's configuration file (httpd.conf)

I have found the answer to this, and it is annoyingly/frustratingly simple! Basically the reply to addresses needed to be added before the from address as such:

$mail->addReplyTo('[email protected]', 'Reply to name');
$mail->SetFrom('[email protected]', 'Mailbox name');

Looking at the phpmailer code in more detail this is the offending line:

public function SetFrom($address, $name = '',$auto=1) {
   $address = trim($address);
   $name = trim(preg_replace('/[\r\n]+/', '', $name)); //Strip breaks and trim
   if (!self::ValidateAddress($address)) {
     $this->SetError($this->Lang('invalid_address').': '. $address);
     if ($this->exceptions) {
       throw new phpmailerException($this->Lang('invalid_address').': '.$address);
     }
     echo $this->Lang('invalid_address').': '.$address;
     return false;
   }
   $this->From = $address;
   $this->FromName = $name;
   if ($auto) {
      if (empty($this->ReplyTo)) {
         $this->AddAnAddress('ReplyTo', $address, $name);
      }
      if (empty($this->Sender)) {
         $this->Sender = $address;
      }
   }
   return true;
}

Specifically this line:

if (empty($this->ReplyTo)) {
   $this->AddAnAddress('ReplyTo', $address, $name);
}

Thanks for your help everyone!

You've to do that in your application layer. If you're using an ORM, it could use annotations (or something similar) to pull references that exist in other collections. I only have worked with Morphia, and the @Reference annotation fetches the referenced entity when queried, so I am able to avoid doing it myself in the code.

For simple test project, g++ or make standalone are good options as already answered:

g++ -o hi hi.cpp

or

make hi

For real projects, however, the usage of a project manager is required. At the time I write this answer, the most used and open-source is cmake (an alternative could be QT qmake ).

Following is a simple CMake example:

Make sure you installed cmake on your linux distribution apt-get install cmake or yum install cmake.

Create a file CMakeLists.txt (the name is important) together with your source hi.cpp

project("hi")

add_executable( hi hi.cpp )

Then compile and run as:

cmake .
make
./hi

This allows the project to scale easily with libraries, sources, and much more. It also makes most IDEs to understand the project properly (Most IDEs accept CMake natively, like kdevelop, qtCreator, etc..)

You could also generate Visual-Studio or XCode projects from CMake, in case you decide to port the software to other platforms in the future.

cmake -G Xcode . #will generate `hi.xcodeproj` you can load on macOS

DECLARE @EndTime AS DATETIME, @StartTime AS DATETIME

SELECT @StartTime = '2013-03-08 08:00:00', @EndTime = '2013-03-08 08:30:00'

SELECT CAST(@EndTime - @StartTime AS TIME)

Result: 00:30:00.0000000

Format result as you see fit.

I have recently installed dlib on python 3.7. First I have installed cmake from anaconda navigator (cmake version 3.14.0) Next i installed visual studio 2019 and installed Desktop development with C++ . Then I do pip install dlib and now its working

based on your input example, this awk line works. (without trailing comma)

awk -vRS="" -vOFS=',' '$1=$1' file

test:

kent$  echo "foo
bar
qux
zuu
sdf
sdfasdf"|awk -vRS="" -vOFS=',' '$1=$1' 
foo,bar,qux,zuu,sdf,sdfasdf

This might also help:

void ButtQuitClick(object sender, EventArgs e)
{
    QuitWin form = new QuitWin();
    form.Show();
}

Change ButtQuit to your button name and also change QuitWin to the name of the form that you made.

When the button is clicked it will open another window, you will need to make another form and a button on your main form for it to work.

You're looking for Enumerable#select (also called find_all):

@fathers.select {|father| father["age"] > 35 }
# => [ { "age" => 40, "father" => "Bob" },
#      { "age" => 50, "father" => "Batman" } ]

Per the documentation, it "returns an array containing all elements of [the enumerable, in this case @fathers] for which block is not false."

For genymotion on mac, I was getting INSTALL_FAILED_NO_MATCHING_ABIS error while installing my apk.

In my project there wasn't any "APP_ABI" but I added it accordingly and it built just one apk for both architectures but it worked. https://stackoverflow.com/a/35565901/3241111

What worked for me (youtube-dl version 2018.03.03, ffprobe 0.5, no avprobe, 3.4.1-tessus, in Hi-Sierra/iMac) was:

brew install libav

(thanks to marciovsena's post on GitHub).

I saw elsewhere that libav might be deprecated in the future, but I'll worry about it when we get there.

I have always found Exceptions are much slower to be handled.

Perhaps a less intensive way would yeild a better, faster, result?

public bool IsValidUri(Uri uri)
{

    using (HttpClient Client = new HttpClient())
    {

    HttpResponseMessage result = Client.GetAsync(uri).Result;
    HttpStatusCode StatusCode = result.StatusCode;

    switch (StatusCode)
    {

        case HttpStatusCode.Accepted:
            return true;
        case HttpStatusCode.OK:
            return true;
         default:
            return false;
        }
    }
}

Then just use:

IsValidUri(new Uri("http://www.google.com/censorship_algorithm"));

Once you have Selected a group of sheets, you can use Selection

Consider:

Sub luxation()
    ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
    Selection.ExportAsFixedFormat _
        Type:=xlTypePDF, _
        Filename:="C:\TestFolder\temp.pdf", _
        Quality:=xlQualityStandard, _
        IncludeDocProperties:=True, _
        IgnorePrintAreas:=False, _
        OpenAfterPublish:=True
End Sub

EDIT#1:

Further testing has reveled that this technique depends on the group of cells selected on each worksheet. To get a comprehensive output, use something like:

Sub Macro1()

   Sheets("Sheet1").Activate
   ActiveSheet.UsedRange.Select
   Sheets("Sheet2").Activate
   ActiveSheet.UsedRange.Select
   Sheets("Sheet3").Activate
   ActiveSheet.UsedRange.Select

   ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
   Selection.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
      "C:\Users\James\Desktop\pdfmaker.pdf", Quality:=xlQualityStandard, _
      IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:= _
      True
End Sub

just seperate the class name with a comma.

Compilation from jonearles' answer, http://kishantha.blogspot.com/2010/03/oracle-enterprise-manager-console.html and http://blog.flimatech.com/2011/07/17/changing-oracle-password-in-11g-using-alter-user-identified-by-values/ (Oracle 11g):

To stop this happening in the future do the following.

• Login to sqlplus as sysdba -> sqlplus "/as sysdba"
• Execute ->ALTER PROFILE DEFAULT LIMIT FAILED_LOGIN_ATTEMPTS UNLIMITED PASSWORD_LIFE_TIME UNLIMITED;

To reset users' status, run the query:

select
'alter user ' || su.name || ' identified by values'
   || ' ''' || spare4 || ';'    || su.password || ''';'
from sys.user$ su 
join dba_users du on ACCOUNT_STATUS like 'EXPIRED%' and su.name = du.username;

and execute some or all of the result set.

The GuidToBinary routine posted by KCD should be tweaked to account for the bit layout of the timestamp in the GUID string. If the string represents a version 1 UUID, like those returned by the uuid() mysql routine, then the time components are embedded in letters 1-G, excluding the D.

12345678-9ABC-DEFG-HIJK-LMNOPQRSTUVW
12345678 = least significant 4 bytes of the timestamp in big endian order
9ABC     = middle 2 timestamp bytes in big endian
D        = 1 to signify a version 1 UUID
EFG      = most significant 12 bits of the timestamp in big endian

When you convert to binary, the best order for indexing would be: EFG9ABC12345678D + the rest.

You don't want to swap 12345678 to 78563412 because big endian already yields the best binary index byte order. However, you do want the most significant bytes moved in front of the lower bytes. Hence, EFG go first, followed by the middle bits and lower bits. Generate a dozen or so UUIDs with uuid() over the course of a minute and you should see how this order yields the correct rank.

select uuid(), 0
union 
select uuid(), sleep(.001)
union 
select uuid(), sleep(.010)
union 
select uuid(), sleep(.100)
union 
select uuid(), sleep(1)
union 
select uuid(), sleep(10)
union
select uuid(), 0;

The first two UUIDs were generated closest in time. They only vary in the last 3 nibbles of the first block. These are the least significant bits of the timestamp, which means we want to push them to the right when we convert this to an indexable byte array. As a counter example, the last ID is the most current, but the KCD's swapping algorithm would put it before the 3rd ID (3e before dc, last bytes from the first block).

The correct order for indexing would be:

1e497556eec5eb6... 
1e497556eec5f10... 
1e497556eec8ddc... 
1e497556eee30d0... 
1e497556efda038... 
1e497556f9641bf... 
1e49755758c3e3e... 

See this article for supporting information: http://mysql.rjweb.org/doc.php/uuid

*** note that I don't split the version nibble from the high 12 bits of the timestamp. This is the D nibble from your example. I just throw it in front. So my binary sequence ends up being DEFG9ABC and so on. This implies that all my indexed UUIDs start with the same nibble. The article does the same thing.

Upgrading from Kepler to Luna worked for me.

I had just added some components for Java 1.8 support. It seems that they where not as compatible as I would like or that I mixed the wrong ones. It really caused a lot of problems. Trying to update the system reported errors as they couldn't fulfill some dependencies. Maven upgrades didn't work. Tried a lot of things.

So, if there is no reason to avoid the upgrade just add the luna repository to avalilable software sites (Luna http://download.eclipse.org/releases/luna/ ) and "check for updates". It is better to have all the components with the same version and there are some nice new features.

Just adding some extra sorting if needed

=QUERY(A2:A,"select A, count(A) where A is not null group by A order by count(A) DESC label A 'Name', count(A) 'Count'",-1)

If you are working with Android's MediaStore database, here is how to store an image and then display it after it is saved.

on button click write this

 Intent in = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            in.putExtra("crop", "true");
            in.putExtra("outputX", 100);
            in.putExtra("outputY", 100);
            in.putExtra("scale", true);
            in.putExtra("return-data", true);

            startActivityForResult(in, 1);

then do this in your activity

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1 && resultCode == RESULT_OK && data != null) {

            Bitmap bmp = (Bitmap) data.getExtras().get("data");

            img.setImageBitmap(bmp);
            btnadd.requestFocus();

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
            byte[] b = baos.toByteArray();
            String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);

            byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
            Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
                    bytarray.length);

        }

    }

It depends on which version of Oracle? Older versions require exp (export), newer versions use expdp (data pump); exp was deprecated but still works most of the time.

Before starting, note that Data Pump exports to the server-side Oracle "directory", which is an Oracle symbolic location mapped in the database to a physical location. There may be a default directory (DATA_PUMP_DIR), check by querying DBA_DIRECTORIES:

  SQL> select * from dba_directories;

... and if not, create one

  SQL> create directory DATA_PUMP_DIR as '/oracle/dumps';
  SQL> grant all on directory DATA_PUMP_DIR to myuser;    -- DBAs dont need this grant

Assuming you can connect as the SYSTEM user, or another DBA, you can export any schema like so, to the default directory:

 $ expdp system/manager schemas=user1 dumpfile=user1.dpdmp

Or specifying a specific directory, add directory=<directory name>:

 C:\> expdp system/manager schemas=user1 dumpfile=user1.dpdmp directory=DUMPDIR

With older export utility, you can export to your working directory, and even on a client machine that is remote from the server, using:

 $ exp system/manager owner=user1 file=user1.dmp

Make sure the export is done in the correct charset. If you haven't setup your environment, the Oracle client charset may not match the DB charset, and Oracle will do charset conversion, which may not be what you want. You'll see a warning, if so, then you'll want to repeat the export after setting NLS_LANG environment variable so the client charset matches the database charset. This will cause Oracle to skip charset conversion.

Example for American UTF8 (UNIX):

 $ export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

Windows uses SET, example using Japanese UTF8:

 C:\> set NLS_LANG=Japanese_Japan.AL32UTF8

More info on Data Pump here: http://docs.oracle.com/cd/B28359_01/server.111/b28319/dp_export.htm#g1022624

Here's another simple solution. The following code will return everything before the '|' character:

if (path.Contains('|'))
   path = path.Split('|')[0];

In fact, you could have as many separators as you want, but assuming you only have one separation character, here is how you would get everything after the '|':

if (path.Contains('|'))
   path = path.Split('|')[1];

(All I changed in the second piece of code was the index of the array.)

You can also encode bytes to Base64. How to get this from a stream see here: How to convert an Stream into a byte[] in C#?

Or I think it should be also possible to use the .ToString() method and encode this.

You can modify the output format:

>>> a = 13.95
>>> a
13.949999999999999
>>> print "%.2f" % a
13.95

Just a note. If you want to compare a string with "" ,in your case, use

If LEN(str) > 0 Then

or even just

If LEN(str) Then

instead.

string s = (string)o; // 1

Throws InvalidCastException if o is not a string. Otherwise, assigns o to s, even if o is null.

string s = o as string; // 2

Assigns null to s if o is not a string or if o is null. For this reason, you cannot use it with value types (the operator could never return null in that case). Otherwise, assigns o to s.

string s = o.ToString(); // 3

Causes a NullReferenceException if o is null. Assigns whatever o.ToString() returns to s, no matter what type o is.

Use 1 for most conversions - it's simple and straightforward. I tend to almost never use 2 since if something is not the right type, I usually expect an exception to occur. I have only seen a need for this return-null type of functionality with badly designed libraries which use error codes (e.g. return null = error, instead of using exceptions).

3 is not a cast and is just a method invocation. Use it for when you need the string representation of a non-string object.

It is best to force the highest mode possible. That can be accomplished by adding:

<meta http-equiv="X-UA-Compatible" content="IE=edge">

and it is always good to include the polyfill library in order to support IE:

<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>

before any script.

Simply You can do

SELECT DATE(date_field) AS date_field FROM table_name

another option is to use an iframe and set the form's target to it.

you may try this (it uses jQuery):

function ajax_form($form, on_complete)
{
    var iframe;

    if (!$form.attr('target'))
    {
        //create a unique iframe for the form
        iframe = $("<iframe></iframe>").attr('name', 'ajax_form_' + Math.floor(Math.random() * 999999)).hide().appendTo($('body'));
        $form.attr('target', iframe.attr('name'));
    }

    if (on_complete)
    {
        iframe = iframe || $('iframe[name="' + $form.attr('target') + '"]');
        iframe.load(function ()
        {
            //get the server response
            var response = iframe.contents().find('body').text();
            on_complete(response);
        });
    }
}

it works well with all browsers, you don't need to serialize or prepare the data. one down side is that you can't monitor the progress.

also, at least for chrome, the request will not appear in the "xhr" tab of the developer tools but under "doc"

@echo off
xcopy ...

Replace ... with the appropriate xcopy arguments to copy what you want copied.

I know this is kind of an old topic, but I would use the Powershell variable

$env:UserProfile 

To use it to get to the desktop, it would be:

cd $env:UserProfile\desktop

This works both locally and remotely on windows 7. Hope this is useful as I ran across a situation where a client machine didn't have a value in $home.

Using ? is much cleaner.

var ? function_if_exists() : function_if_doesnt_exist();

This solution is quick and neat.

basically you just prevent double touch from the base styles in your app and implement standard on click listener. This works like a charm with touches at the same time of different views.

<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
...
<item name="android:splitMotionEvents">false</item>
<item name="android:windowEnableSplitTouch">false</item>
</style>

If your app uses some kind of gesture event this is not the right answer.

Do you really want to style the <div>? Or do you want to style the <input type="button">? You should use the correct selector if you want the latter:

input[type=button] {
    color:#08233e;
    font:2.4em Futura, ‘Century Gothic’, AppleGothic, sans-serif;
    font-size:70%;
    /* ... other rules ... */
    cursor:pointer;
}

input[type=button]:hover {
    background-color:rgba(255,204,0,0.8);
}

"Is there a definition of exactly what width:auto does mean? The CSS spec seems vague to me, but maybe I missed the relevant section."

No one actually answered the above part of the original poster's question.

Here's the answer: http://www.456bereastreet.com/archive/201112/the_difference_between_widthauto_and_width100/

As long as the value of width is auto, the element can have horizontal margin, padding and border without becoming wider than its container...

On the other hand, if you specify width:100%, the element’s total width will be 100% of its containing block plus any horizontal margin, padding and border... This may be what you want, but most likely it isn’t.

To visualise the difference I made an example: http://www.456bereastreet.com/lab/width-auto/

It works perfectly. I have gcc compiler C++11 ready. Try this and you'll see:

#include <iostream>

using namespace std;

int main()
{
    int pause;

    struct Customer
    {
           int uid;
           string name;
    };

    Customer customerRecords[2];
    customerRecords[0] = {25, "Bob Jones"};
    customerRecords[1] = {26, "Jim Smith"};
    cout << customerRecords[0].uid << " " << customerRecords[0].name << endl;
    cout << customerRecords[1].uid << " " << customerRecords[1].name << endl;
    cin >> pause;
return 0;
}

I hope the following code will solve your problem pretty well.

//Empty all tables' contents

$result_t = mysql_query("SHOW TABLES");
while($row = mysql_fetch_assoc($result_t))
{
mysql_query("TRUNCATE " . $row['Tables_in_' . $mysql_database]);
}
// Temporary variable, used to store current query
$templine = '';
// Read in entire file
$lines = file($filename);
// Loop through each line
foreach ($lines as $line)
{
// Skip it if it's a comment
if (substr($line, 0, 2) == '--' || $line == '')
    continue;

// Add this line to the current segment
$templine .= $line;
// If it has a semicolon at the end, it's the end of the query
if (substr(trim($line), -1, 1) == ';')
{
    // Perform the query
    mysql_query($templine) or print('Error performing query \'<strong>' . $templine . '\': ' . mysql_error() . '<br /><br />');
    // Reset temp variable to empty
    $templine = '';
}
}

?>

public string BuildAbsolute(PathString path, QueryString query = default(QueryString), FragmentString fragment = default(FragmentString))
{
    var rq = httpContext.Request;
    return Microsoft.AspNetCore.Http.Extensions.UriHelper.BuildAbsolute(rq.Scheme, rq.Host, rq.PathBase, path, query, fragment);
}

purls $.params() used without a parameter will give you a key-value object of the parameters.

jQuerys $.param() will build a querystring from the supplied object/array.

var params = parsedUrl.param();
delete params["page"];

var newUrl = "?page=" + $(this).val() + "&" + $.param(params);

Update
I've no idea why I used delete here...

var params = parsedUrl.param();
params["page"] = $(this).val();

var newUrl = "?" + $.param(params);

Modern C, aka C99, has variable length arrays, VLA. Unfortunately, not all compilers support this but if yours does this would be an alternative.

I dont think default backup location is stored within the SQL server itself. The settings are stored in Registry. Look for "BackupDirectory" key and you'll find the default backup.

The "msdb.dbo.backupset" table consists of list of backups taken, if no backup is taken for a database, it won't show you anything

Swift 4 and above

I have created an extension

extension UIViewController {
  public func addActionSheetForiPad(actionSheet: UIAlertController) {
    if let popoverPresentationController = actionSheet.popoverPresentationController {
      popoverPresentationController.sourceView = self.view
      popoverPresentationController.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
      popoverPresentationController.permittedArrowDirections = []
    }
  }
}

How to use:

let actionSheetVC = UIAlertController(title: "Title", message: nil, preferredStyle: .actionSheet)
addActionSheetForIpad(actionSheet: actionSheetVC)
present(actionSheetVC, animated: true, completion: nil)

did you tried converting the first char of the string to lowercase on if(fruits[i].charAt(0) == currChar) and char currChar = fruits[0].charAt(0) statements?

You can use javascript to access elements on the page and modify their contents. So for example you might have a page with some HTML markup like so:

<div id="MyEdit">
    This text will change
</div>

You can use javascript to change the content like so...

document.getElementById("MyEdit").innerHTML = "My new text!";?

Here is a working example

You can also look at using the JQuery javascript library for DOM manipulation, it has some great features to make things like this very easy.

For example, with JQuery, you could do this to acheive the same result...

$("#MyEdit").html("My new text!");

Here is a working example of the JQuery version

Based on this example you provided in your post. The following JQuery would work for you:

var x = "hello wolrd";
$("p").html(x);

Here is the working version

Using a P tag like this however is not recommended. You would ideally want to use an element with a unique ID so you can ensure you are selecting the correct one with JQuery.

We can as well start an application by knowing application type and feeding it with data:

adb shell am start -d "file:///sdcard/sample.3gp" -t "video/3gp" -a android.intent.action.VIEW

This command displays available Video Players to play sample.3gp file

There are method join for string objects:

".".join(("a","b","c"))

Due to the above mentioned problems, I prefer table value functions.

If you have this:

CREATE VIEW [dbo].[MyView] AS SELECT A, B FROM dbo.Something

create this:

CREATE FUNCTION MyFunction() RETURNS TABLE AS RETURN (SELECT * FROM [dbo].[MyView])

Then you simply import the function rather than the view.

Believe this occurs because you have a child repository "submodule" that has changes which have not been staged and committed.

Had a similar problem, where my IDE kept reporting uncommitted changes, and running the stage (git add .) and commit (git commit -m "message") commands had no effect. Thinking about this in hindsight, it's probably because the child repository had the changes that needed to be staged and committed, not the parent repository.

Steps that fixed the issue

1. cd into the submodule (has a hidden folder named .git) and execute the commands to stage (git add .) and commit (git commit -m "Update child repo")
2. cd .. back to the parent repo, and execute the commands to stage (git add .) and commit (git commit -m "Update parent repo")

Advice that wasn't helpful

• sudo rm -Rf .git == DO NOT USE THIS COMMAND == it permanently deletes submodule repository history (the purpose of GIT)
• git add -A === Added untracked files, but didn't fix issue

You can just forgo the quotes for alphanumeric attributes:

echo "<font color=red> XHTML is not a thing anymore. </font>";
echo "<div class=editorial-note> There, I said it. </div>";

Is perfectly valid in HTML, and though still shunned, absolutely en vogue since HTML5.

CAVEATS

• It's only valid for mostly alphanumeric and dash combinations.
• Never ever do this with user input appended to attributes (those need quoting and htmlspecialchars or some whitelisting).
• See also: When the attribute value can remain unquoted in HTML5
• In other news: <font> specifically is somewhat outdated however.

I was trying to step through code in RegisterRoutes() called from Application start and not hitting my breakpoint. I determined Application_Start was not getting called. I had to make a change to make a superficial change to App_start/RouteConfig.cs and save it before Application_Start would get called. I guess these files get cached somewhere and are not called unless a change is made.

You can combine your counts like you were doing before, but then you could sum them all up a number of ways, one of which is shown below:

SELECT SUM(A) 
FROM
(
    SELECT 1 AS A
    UNION ALL 
    SELECT 1 AS A
    UNION ALL
    SELECT 1 AS A
    UNION ALL
    SELECT 1 AS A
) AS B

Not knowing time cost of shared_copy copy operation where atomic increment and decrement is in, I suffered from much higher CPU usage problem. I never expected atomic increment and decrement may take so much cost.

Following my test result, int32 atomic increment and decrement takes 2 or 40 times than non-atomic increment and decrement. I got it on 3GHz Core i7 with Windows 8.1. The former result comes out when no contention occurs, the latter when high possibility of contention occurs. I keep in mind that atomic operations are at last hardware based lock. Lock is lock. Bad to performance when contention occurs.

Experiencing this, I always use byref(const shared_ptr&) than byval(shared_ptr).

Dicts mixed with Arrays

• The answer at Attempt 3: Just Right (so far) from BlissRage's answer does not properly handle arrays elements. I'm including a patch in case anyone needs it. The method is handles list with the statement block of if isinstance(v, list):, which scrubs the list using the original scrub_dict(d) implementation.

    @staticmethod
    def scrub_dict(d):
        new_dict = {}
        for k, v in d.items():
            if isinstance(v, dict):
                v = scrub_dict(v)
            if isinstance(v, list):
                v = scrub_list(v)
            if not v in (u'', None, {}):
                new_dict[k] = v
        return new_dict

    @staticmethod
    def scrub_list(d):
        scrubbed_list = []
        for i in d:
            if isinstance(i, dict):
                i = scrub_dict(i)
            scrubbed_list.append(i)
        return scrubbed_list

Let me post a solution here for C++03 that I consider the cleanest possible.*

#define DECLARE_LAMBDA(NAME, RETURN_TYPE, FUNCTION) \
    struct { RETURN_TYPE operator () FUNCTION } NAME;

...

int main(){
  DECLARE_LAMBDA(demoLambda, void, (){ cout<<"I'm a lambda!"<<endl; });
  demoLambda();

  DECLARE_LAMBDA(plus, int, (int i, int j){
    return i+j;
  });
  cout << "plus(1,2)=" << plus(1,2) << endl;
  return 0;
}

(*) in the C++ world using macros is never considered clean.

If by "restart", you mean to start a new 4 second interval at this moment, then you must stop and restart the timer.

function myFn() {console.log('idle');}

var myTimer = setInterval(myFn, 4000);

// Then, later at some future time, 
// to restart a new 4 second interval starting at this exact moment in time
clearInterval(myTimer);
myTimer = setInterval(myFn, 4000);

You could also use a little timer object that offers a reset feature:

function Timer(fn, t) {
    var timerObj = setInterval(fn, t);

    this.stop = function() {
        if (timerObj) {
            clearInterval(timerObj);
            timerObj = null;
        }
        return this;
    }

    // start timer using current settings (if it's not already running)
    this.start = function() {
        if (!timerObj) {
            this.stop();
            timerObj = setInterval(fn, t);
        }
        return this;
    }

    // start with new or original interval, stop current interval
    this.reset = function(newT = t) {
        t = newT;
        return this.stop().start();
    }
}

Usage:

var timer = new Timer(function() {
    // your function here
}, 5000);


// switch interval to 10 seconds
timer.reset(10000);

// stop the timer
timer.stop();

// start the timer
timer.start();

Another answer: in some contexts, it makes sense to define your enumeration in a non-code format, like a CSV, YAML, or XML file, and then generate both the C++ enumeration code and the to-string code from the definition. This approach may or may not be practical in your application, but it's something to keep in mind.

The differences between Model() and Model.objects.create() are the following:

1. INSERT vs UPDATE

   Model.save() does either INSERT or UPDATE of an object in a DB, while Model.objects.create() does only INSERT.

   Model.save() does

   • UPDATE If the object’s primary key attribute is set to a value that evaluates to True

   • INSERT If the object’s primary key attribute is not set or if the UPDATE didn’t update anything (e.g. if primary key is set to a value that doesn’t exist in the database).

2. Existing primary key

   If primary key attribute is set to a value and such primary key already exists, then Model.save() performs UPDATE, but Model.objects.create() raises IntegrityError.

   Consider the following models.py:

   class Subject(models.Model):
      subject_id = models.PositiveIntegerField(primary_key=True, db_column='subject_id')
      name = models.CharField(max_length=255)
      max_marks = models.PositiveIntegerField()
   

   1. Insert/Update to db with Model.save()

      physics = Subject(subject_id=1, name='Physics', max_marks=100)
      physics.save()
      math = Subject(subject_id=1, name='Math', max_marks=50)  # Case of update
      math.save()
      

      Result:

      Subject.objects.all().values()
      <QuerySet [{'subject_id': 1, 'name': 'Math', 'max_marks': 50}]>
      

   2. Insert to db with Model.objects.create()

      Subject.objects.create(subject_id=1, name='Chemistry', max_marks=100)
      IntegrityError: UNIQUE constraint failed: m****t.subject_id
      

   Explanation: In the example, math.save() does an UPDATE (changes name from Physics to Math, and max_marks from 100 to 50), because subject_id is a primary key and subject_id=1 already exists in the DB. But Subject.objects.create() raises IntegrityError, because, again the primary key subject_id with the value 1 already exists.

3. Forced insert

   Model.save() can be made to behave as Model.objects.create() by using force_insert=True parameter: Model.save(force_insert=True).

4. Return value

   Model.save() return None where Model.objects.create() return model instance i.e. package_name.models.Model

Conclusion: Model.objects.create() does model initialization and performs save() with force_insert=True.

Excerpt from the source code of Model.objects.create()

def create(self, **kwargs):
    """
    Create a new object with the given kwargs, saving it to the database
    and returning the created object.
    """
    obj = self.model(**kwargs)
    self._for_write = True
    obj.save(force_insert=True, using=self.db)
    return obj

I think you don't have to use sub query in this scenario.You can directly left outer join the DEPRMNT table .

While using Left Outer Join ,don't use columns in the RHS table of the join in the where condition, you ll get wrong output

I found out the answer is probably:

A NativeQuery lets you execute native SQL, mapping the results according to your specifications. Such a specification that describes how an SQL result set is mapped to a Doctrine result is represented by a ResultSetMapping.

Source: Native SQL.

\d is a digit (a character in the range 0-9), and + means 1 or more times. So, \d+ is 1 or more digits.

This is about as simple as regular expressions get. You should try reading up on regular expressions a little bit more. Google has a lot of results for regular expression tutorial, for instance. Or you could try using a tool like the free Regex Coach that will let you enter a regular expression and sample text, then indicate what (if anything) matches the regex.

This may also happen if you have a slash before the folder name:

path = '/folder1/folder2'

OSError: [Errno 13] Permission denied: '/folder1'

comes up with an error but this one works fine:

path = 'folder1/folder2'

Today things have changed a little.

Now we avoid use ProgressDialog to show spinning progress:

If you want to put in your app a spinning progress you should use an Activity indicators:

http://developer.android.com/design/building-blocks/progress.html#activity

I've written the tests that compare using regular expressions (as per other answers) against not using regular expressions. Tests done on a quad core OSX10.8 machine running Java 1.6

Interestingly using regular expressions turns out to be about 5-10 times slower than manually iterating over a string. Furthermore the isAlphanumeric2() function is marginally faster than isAlphanumeric(). One supports the case where extended Unicode numbers are allowed, and the other is for when only standard ASCII numbers are allowed.

public class QuickTest extends TestCase {

    private final int reps = 1000000;

    public void testRegexp() {
        for(int i = 0; i < reps; i++)
            ("ab4r3rgf"+i).matches("[a-zA-Z0-9]");
    }

public void testIsAlphanumeric() {
    for(int i = 0; i < reps; i++)
        isAlphanumeric("ab4r3rgf"+i);
}

public void testIsAlphanumeric2() {
    for(int i = 0; i < reps; i++)
        isAlphanumeric2("ab4r3rgf"+i);
}

    public boolean isAlphanumeric(String str) {
        for (int i=0; i<str.length(); i++) {
            char c = str.charAt(i);
            if (!Character.isLetterOrDigit(c))
                return false;
        }

        return true;
    }

    public boolean isAlphanumeric2(String str) {
        for (int i=0; i<str.length(); i++) {
            char c = str.charAt(i);
            if (c < 0x30 || (c >= 0x3a && c <= 0x40) || (c > 0x5a && c <= 0x60) || c > 0x7a)
                return false;
        }
        return true;
    }

}

Go to project properties -> configurations properties -> C/C++ -> treats warning as error -> No (/WX-).

You can use the shortcut -I for tar's --use-compress-program switch, and invoke pbzip2 for bzip2 compression on multiple cores:

tar -I pbzip2 -cf OUTPUT_FILE.tar.bz2 DIRECTORY_TO_COMPRESS/

In C++ you can declare a string like this:

#include <string>

using namespace std;

int main()
{
    string str1("argue2000"); //define a string and Initialize str1 with "argue2000"    
    string str2 = "argue2000"; // define a string and assign str2 with "argue2000"
    string str3;  //just declare a string, it has no value
    return 1;
}

Another Solution in Case You Don't Have Control Over Dynamic Content

This works if you didn't load your element through a directive (ie. like in the example in the commented jsfiddles).

Wrap up Your Content

Wrap your content in a div so that you can select it if you are using JQuery. You an also opt to use native javascript to get your element.

<div class="selector">
    <grid-filter columnname="LastNameFirstName" gridname="HomeGrid"></grid-filter>
</div>

Use Angular Injector

You can use the following code to get a reference to $compile if you don't have one.

$(".selector").each(function () {
    var content = $(this);
    angular.element(document).injector().invoke(function($compile) {
        var scope = angular.element(content).scope();
        $compile(content)(scope);
    });
});

Summary

The original post seemed to assume you had a $compile reference handy. It is obviously easy when you have the reference, but I didn't so this was the answer for me.

One Caveat of the previous code

If you are using a asp.net/mvc bundle with minify scenario you will get in trouble when you deploy in release mode. The trouble comes in the form of Uncaught Error: [$injector:unpr] which is caused by the minifier messing with the angular javascript code.

Here is the way to remedy it:

Replace the prevous code snippet with the following overload.

...
angular.element(document).injector().invoke(
[
    "$compile", function($compile) {
        var scope = angular.element(content).scope();
        $compile(content)(scope);
    }
]);

This caused a lot of grief for me before I pieced it together.

Thanks for this! I'd liek to add a little riff on the J-P's answer - I don't know if this will help anyone, but this way you don't have to create an array of images, and you can preload all your large images if you name your thumbs correctly. This is handy because I have someone who is writing all the pages in html, and it ensures one less step for them to do - eliminating the need to create the image array, and another step where things could get screwed up.

$("img").each(function(){
    var imgsrc = $(this).attr('src');
    if(imgsrc.match('_th.jpg') || imgsrc.match('_home.jpg')){
      imgsrc = thumbToLarge(imgsrc);
      (new Image()).src = imgsrc;   
    }
});

Basically, for each image on the page it grabs the src of each image, if it matches certain criteria (is a thumb, or home page image) it changes the name(a basic string replace in the image src), then loads the images.

In my case the page was full of thumb images all named something like image_th.jpg, and all the corresponding large images are named image_lg.jpg. The thumb to large just replaces the _th.jpg with _lg.jpg and then preloads all the large images.

Hope this helps someone.

You need to use the various Bootstrap 4 centering methods...

• Use text-center for inline elements.
• Use justify-content-center for flexbox elements (ie; form-inline)

https://codeply.com/go/Am5LvvjTxC

Also, to offset the column, the col-sm-* must be contained within a .row, and the .row must be in a container...

<section id="cover">
    <div id="cover-caption">
        <div id="container" class="container">
            <div class="row">
                <div class="col-sm-10 offset-sm-1 text-center">
                    <h1 class="display-3">Welcome to Bootstrap 4</h1>
                    <div class="info-form">
                        <form action="" class="form-inline justify-content-center">
                            <div class="form-group">
                                <label class="sr-only">Name</label>
                                <input type="text" class="form-control" placeholder="Jane Doe">
                            </div>
                            <div class="form-group">
                                <label class="sr-only">Email</label>
                                <input type="text" class="form-control" placeholder="[email protected]">
                            </div>
                            <button type="submit" class="btn btn-success ">okay, go!</button>
                        </form>
                    </div>
                    <br>

                    <a href="#nav-main" class="btn btn-secondary-outline btn-sm" role="button">?</a>
                </div>
            </div>
        </div>
    </div>

I found the solution to the white bars here:

Set viewport-fit=cover on the viewport <meta> tag, i.e.:

<meta name="viewport" content="initial-scale=1, width=device-width, height=device-height, viewport-fit=cover">

The white bars in UIWebView then disappear:

The solution to remove the black areas (provided by @dpogue in a comment below) is to use LaunchStoryboard images with cordova-plugin-splashscreen to replace the legacy launch images, used by Cordova by default. To do so, add the following to the iOS platform in config.xml:

<platform name="ios">    
    <splash src="res/screen/ios/Default@2x~iphone~anyany.png" />
    <splash src="res/screen/ios/Default@2x~iphone~comany.png" />
    <splash src="res/screen/ios/Default@2x~iphone~comcom.png" />
    <splash src="res/screen/ios/Default@3x~iphone~anyany.png" />
    <splash src="res/screen/ios/Default@3x~iphone~anycom.png" />
    <splash src="res/screen/ios/Default@3x~iphone~comany.png" />
    <splash src="res/screen/ios/Default@2x~ipad~anyany.png" />
    <splash src="res/screen/ios/Default@2x~ipad~comany.png" />   

    <!-- more iOS config... -->
</platform>

Then create the images with the following dimensions in res/screen/ios (remove any existing ones):

Default@2x~iphone~anyany.png - 1334x1334
Default@2x~iphone~comany.png - 750x1334
Default@2x~iphone~comcom.png - 1334x750
Default@3x~iphone~anyany.png - 2208x2208
Default@3x~iphone~anycom.png - 2208x1242
Default@3x~iphone~comany.png - 1242x2208
Default@2x~ipad~anyany.png - 2732x2732
Default@2x~ipad~comany.png - 1278x2732

Once the black bars are removed, there's another thing that's different about the iPhone X to address: The status bar is larger than 20px due to the "notch", which means any content at the far top of your Cordova app will be obscured by it:

Rather than hard-coding a padding in pixels, you can handle this automatically in CSS using the new safe-area-inset-* constants in iOS 11.

Note: in iOS 11.0 the function to handle these constants was called constant() but in iOS 11.2 Apple renamed it to env() (see here), therefore to cover both cases you need to overload the CSS rule with both and rely on the CSS fallback mechanism to apply the appropriate one:

body{
    padding-top: constant(safe-area-inset-top);
    padding-top: env(safe-area-inset-top);
}

The result is then as desired: the app content covers the full screen, but is not obscured by the "notch":

I've created a Cordova test project which illustrates the above steps: webview-test.zip

Notes:

Footer buttons

• If your app has footer buttons (as mine does), you will also need to apply safe-area-inset-bottom to avoid them being overlapped by the virtual Home button on iPhone X.
• In my case, I couldn't apply this to <body> as the footer is absolutely positioned, so I needed to apply it directly to the footer:

.toolbar-footer{
    margin-bottom: constant(safe-area-inset-bottom);
    margin-bottom: env(safe-area-inset-bottom);
}

cordova-plugin-statusbar

• The status bar size has changed on iPhone X, so older versions of cordova-plugin-statusbar display incorrectly on iPhone X
• Mike Hartington has created this pull request which applies the necessary changes.
• This was merged into the [email protected] release, so make sure you're using at least this version to apply to safe-area-insets

splashscreen

• The LaunchScreen storyboard constraints changed on iOS 11/iPhone X, meaning the splashscreen appeared to "jump" on launch when using existing versions of the plugin (see here).
• This was captured in bug report CB-13505, fixed PR cordova-ios#354 and released in [email protected], so make sure you're using a recent version of the cordova-ios platform.

device orientation

• When using UIWebView on iOS 11.0, rotating from portrait > landscape > portrait causes the safe-area-inset not to be re-applied, causing the content to be obscured by the notch again (as highlighted by jms in a comment below).
• Also happens if app is launched in landscape then rotated to portrait
• This doesn't happen when using WKWebView via cordova-plugin-wkwebview-engine.
• Radar report: http://www.openradar.me/radar?id=5035192880201728
• Update: this appears to have been fixed in iOS 11.1

For reference, this is the original Cordova issue I opened which captures this: https://issues.apache.org/jira/browse/CB-13273

I really didn't want to type \n every single time and @matthause's answer didn't seem to work for me, so I created my own class

class File():

    def __init__(self, name, mode='w'):
        self.f = open(name, mode, buffering=1)
        
    def write(self, string, newline=True):
        if newline:
            self.f.write(string + '\n')
        else:
            self.f.write(string)

And here it is implemented

f = File('console.log')

f.write('This is on the first line')
f.write('This is on the second line', newline=False)
f.write('This is still on the second line')
f.write('This is on the third line')

This should show in the log file as

This is on the first line
This is on the second lineThis is still on the second line
This is on the third line

If you don't have a page which is accessing the websocket, you can open up the Chrome console and type your JavaScript in:

var webSocket = new WebSocket('ws://address:port');
webSocket.onmessage = function(data) { console.log(data); }

This will open up the web socket so you can see it in the network tab and in the console.

# Let's add key:value to a dictionary, the functional way 
# Create your dictionary class 
class my_dictionary(dict): 
    # __init__ function 
    def __init__(self): 
        self = dict()   
    # Function to add key:value 
    def add(self, key, value): 
        self[key] = value 
# Main Function 
dict_obj = my_dictionary() 
limit = int(input("Enter the no of key value pair in a dictionary"))
c=0
while c < limit :   
    dict_obj.key = input("Enter the key: ") 
    dict_obj.value = input("Enter the value: ") 
    dict_obj.add(dict_obj.key, dict_obj.value) 
    c += 1
print(dict_obj) 

Misconceptions

There are few common misconceptions regarding WebSocket and Socket.IO:

1. The first misconception is that using Socket.IO is significantly easier than using WebSocket which doesn't seem to be the case. See examples below.

2. The second misconception is that WebSocket is not widely supported in the browsers. See below for more info.

3. The third misconception is that Socket.IO downgrades the connection as a fallback on older browsers. It actually assumes that the browser is old and starts an AJAX connection to the server, that gets later upgraded on browsers supporting WebSocket, after some traffic is exchanged. See below for details.

My experiment

I wrote an npm module to demonstrate the difference between WebSocket and Socket.IO:

• https://www.npmjs.com/package/websocket-vs-socket.io
• https://github.com/rsp/node-websocket-vs-socket.io

It is a simple example of server-side and client-side code - the client connects to the server using either WebSocket or Socket.IO and the server sends three messages in 1s intervals, which are added to the DOM by the client.

Server-side

Compare the server-side example of using WebSocket and Socket.IO to do the same in an Express.js app:

WebSocket Server

WebSocket server example using Express.js:

var path = require('path');
var app = require('express')();
var ws = require('express-ws')(app);
app.get('/', (req, res) => {
  console.error('express connection');
  res.sendFile(path.join(__dirname, 'ws.html'));
});
app.ws('/', (s, req) => {
  console.error('websocket connection');
  for (var t = 0; t < 3; t++)
    setTimeout(() => s.send('message from server', ()=>{}), 1000*t);
});
app.listen(3001, () => console.error('listening on http://localhost:3001/'));
console.error('websocket example');

Source: https://github.com/rsp/node-websocket-vs-socket.io/blob/master/ws.js

Socket.IO Server

Socket.IO server example using Express.js:

var path = require('path');
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
app.get('/', (req, res) => {
  console.error('express connection');
  res.sendFile(path.join(__dirname, 'si.html'));
});
io.on('connection', s => {
  console.error('socket.io connection');
  for (var t = 0; t < 3; t++)
    setTimeout(() => s.emit('message', 'message from server'), 1000*t);
});
http.listen(3002, () => console.error('listening on http://localhost:3002/'));
console.error('socket.io example');

Source: https://github.com/rsp/node-websocket-vs-socket.io/blob/master/si.js

Client-side

Compare the client-side example of using WebSocket and Socket.IO to do the same in the browser:

WebSocket Client

WebSocket client example using vanilla JavaScript:

var l = document.getElementById('l');
var log = function (m) {
    var i = document.createElement('li');
    i.innerText = new Date().toISOString()+' '+m;
    l.appendChild(i);
}
log('opening websocket connection');
var s = new WebSocket('ws://'+window.location.host+'/');
s.addEventListener('error', function (m) { log("error"); });
s.addEventListener('open', function (m) { log("websocket connection open"); });
s.addEventListener('message', function (m) { log(m.data); });

Source: https://github.com/rsp/node-websocket-vs-socket.io/blob/master/ws.html

Socket.IO Client

Socket.IO client example using vanilla JavaScript:

var l = document.getElementById('l');
var log = function (m) {
    var i = document.createElement('li');
    i.innerText = new Date().toISOString()+' '+m;
    l.appendChild(i);
}
log('opening socket.io connection');
var s = io();
s.on('connect_error', function (m) { log("error"); });
s.on('connect', function (m) { log("socket.io connection open"); });
s.on('message', function (m) { log(m); });

Source: https://github.com/rsp/node-websocket-vs-socket.io/blob/master/si.html

Network traffic

To see the difference in network traffic you can run my test. Here are the results that I got:

WebSocket Results

2 requests, 1.50 KB, 0.05 s

From those 2 requests:

1. HTML page itself
2. connection upgrade to WebSocket

(The connection upgrade request is visible on the developer tools with a 101 Switching Protocols response.)

Socket.IO Results

6 requests, 181.56 KB, 0.25 s

From those 6 requests:

1. the HTML page itself
2. Socket.IO's JavaScript (180 kilobytes)
3. first long polling AJAX request
4. second long polling AJAX request
5. third long polling AJAX request
6. connection upgrade to WebSocket

Screenshots

Socket.IO results that I got on localhost:

Test yourself

Quick start:

# Install:
npm i -g websocket-vs-socket.io
# Run the server:
websocket-vs-socket.io

Open http://localhost:3001/ in your browser, open developer tools with Shift+Ctrl+I, open the Network tab and reload the page with Ctrl+R to see the network traffic for the WebSocket version.

Open http://localhost:3002/ in your browser, open developer tools with Shift+Ctrl+I, open the Network tab and reload the page with Ctrl+R to see the network traffic for the Socket.IO version.

To uninstall:

# Uninstall:
npm rm -g websocket-vs-socket.io

Browser compatibility

As of June 2016 WebSocket works on everything except Opera Mini, including IE higher than 9.

This is the browser compatibility of WebSocket on Can I Use as of June 2016:

See http://caniuse.com/websockets for up-to-date info.

Does the user that you are using to connect to the database (user A in this example) have SELECT access on the objects in the PCT schema? Assuming that A does not have this access, you would get the "table or view does not exist" error.

Most likely, you need your DBA to grant user A access to whatever tables in the PCT schema that you need. Something like

GRANT SELECT ON pct.pi_int
   TO a;

Once that is done, you should be able to refer to the objects in the PCT schema using the syntax pct.pi_int as you demonstrated initially in your question. The bracket syntax approach will not work.

To get around sandboxing of SCM stored Groovy scripts, I recommend to run the script as Groovy Command (instead of Groovy Script file):

import hudson.FilePath
final GROOVY_SCRIPT = "workspace/relative/path/to/the/checked/out/groovy/script.groovy"

evaluate(new FilePath(build.workspace, GROOVY_SCRIPT).read().text)

in such case, the groovy script is transferred from the workspace to the Jenkins Master where it can be executed as a system Groovy Script. The sandboxing is suppressed as long as the Use Groovy Sandbox is not checked.

Move temporarily .gitignore to .gitignore.bck

Check out Environment.NewLine. As for web pages, break lines with <br> or <p></p> tags.

import os
import shutil
os.chdir('C:\\') #Make sure you add your source and destination path below

dir_src = ("C:\\foooo\\")
dir_dst = ("C:\\toooo\\")

for filename in os.listdir(dir_src):
    if filename.endswith('.txt'):
        shutil.copy( dir_src + filename, dir_dst)
    print(filename)

It would help if you showed the code you are using for the simple test program. Put directly into the interpreter this seems to work.

>>> def pyth_test (x1, x2):
...     print x1 + x2
... 
>>> pyth_test(1, 2)
3
>>> 

If you want to have unique elements in your list, then why not use a set, if of course, order does not matter for you: -

>>> s = set()
>>> s.add(2)
>>> s.add(4)
>>> s.add(5)
>>> s.add(2)
>>> s
39: set([2, 4, 5])

If order is a matter of concern, then you can use: -

>>> def addUnique(l, num):
...     if num not in l:
...         l.append(num)
...     
...     return l

You can also find an OrderedSet recipe, which is referred to in Python Documentation

If you are on windows and you encountered the same problem, try to kill the adb.exe process from task manager and then try to run your app again.

DPAPI is just for this purpose. Use DPAPI to encrypt the password the first time the user enters is, store it in a secure location (User's registry, User's application data directory, are some choices). Whenever the app is launched, check the location to see if your key exists, if it does use DPAPI to decrypt it and allow access, otherwise deny it.

problem is that the collapse item (div) is nested in the table elements. The div is hidden, the tr and td of the table are still visible and some css-styles are applied to them (border and padding).
Why are you using tables? Is there a reason for? When you dont´t have to use them, dont´use them :-)

It's working.

my solution is:

1.create a test.conf into /etc/httpd/conf.d/test.conf

2.wrote some rule, like:

<Directory "/var/www/html/test">
RewriteEngine On
RewriteRule ^link([^/]*).html$ rewrite.php?link=$1 [L]
</Directory>

3.restart your Apache server.

4.try again yourself.

Efficiency isn't going to matter for something like this in 99.999999% of situations. Do whatever is easier to read and or maintain.

In my apps I usually rely on classes to provide hiding and showing, for example .addClass('isHidden')/.removeClass('isHidden') which would allow me to animate things with CSS3 if I wanted to. It provides more flexibility.

[System.Diagnostics.FileVersionInfo]::GetVersionInfo("Path\To\File.dll")

You can use Load function

Load TableName fullfilepath; 

parseFloat($(this).css('marginBottom'))

Even if marginBottom defined in em, the value inside of parseFloat above will be in px, as it's a calculated CSS property.

Adding to Rob?'s answer: in case you want to print rather large numbers, using thousand separators can be a great help (note the comma).

>>> f'{a*1000:,.2f}'
'10,123.40'

How about:

:g/^[ \t]*$/d

All of these answers miss an important distinction. update() is used to (re)attach your object graph to a Session. The objects you pass it are the ones that are made managed.

merge() is actually not a (re)attachment API. Notice merge() has a return value? That's because it returns you the managed graph, which may not be the graph you passed it. merge() is a JPA API and its behavior is governed by the JPA spec. If the object you pass in to merge() is already managed (already associated with the Session) then that's the graph Hibernate works with; the object passed in is the same object returned from merge(). If, however, the object you pass into merge() is detached, Hibernate creates a new object graph that is managed and it copies the state from your detached graph onto the new managed graph. Again, this is all dictated and governed by the JPA spec.

In terms of a generic strategy for "make sure this entity is managed, or make it managed", it kind of depends on if you want to account for not-yet-inserted data as well. Assuming you do, use something like

if ( session.contains( myEntity ) ) {
    // nothing to do... myEntity is already associated with the session
}
else {
    session.saveOrUpdate( myEntity );
}

Notice I used saveOrUpdate() rather than update(). If you do not want not-yet-inserted data handled here, use update() instead...

Answers here are a bit outdated. Though the code remains the same there are some changes in the behavior.

public class MyListActivity extends ListActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        TextView footerView = (TextView) ((LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.footer_view, null, false);
        getListView().addFooterView(footerView);
        setListAdapter(new ArrayAdapter<String>(this, getResources().getStringArray(R.array.news)));
    }
}

Info about addFooterView() method

Add a fixed view to appear at the bottom of the list. If addFooterView() is called more than once, the views will appear in the order they were added. Views added using this call can take focus if they want.

Most of the answers above stress very important point -

addFooterView() must be called before calling setAdapter().This is so ListView can wrap the supplied cursor with one that will also account for header and footer views.

From Kitkat this has changed.

Note: When first introduced, this method could only be called before setting the adapter with setAdapter(ListAdapter). Starting with KITKAT, this method may be called at any time. If the ListView's adapter does not extend HeaderViewListAdapter, it will be wrapped with a supporting instance of WrapperListAdapter.

How do you handle oncut, oncopy, and onpaste in jQuery?

Catch paste input

code

$(document).ready(function() {
    var $editor    = $('#editor');
    var $clipboard = $('<textarea />').insertAfter($editor);

    if(!document.execCommand('StyleWithCSS', false, false)) {

    }

    $editor.on('paste, keydown', function() {

});

ContentDescription needed for the Android accessibility. Particularly for the screen reader feature. If you don't support Android accessibility you can ignore it with setup Lint.

So just create lint.xml.

<?xml version="1.0" encoding="UTF-8"?>
<lint>

    <issue id="ContentDescription" severity="ignore" />

</lint>

And put it to the app folder.

You can use other ports like the following:

rails server -p 3001

Normally in your terminal you can try Ctrl + C to shutdown the server.

The other way to kill the Ruby on Rails default server (which is WEBrick) is:

kill -INT $(cat tmp/pids/server.pid)

In your terminal to find out the PID of the process:

$ lsof -wni tcp:3000

Then, use the number in the PID column to kill the process:

For example:

$ kill -9 PID

And some of the other answers i found is:

To stop the rails server while it's running, press:

CTRL-C
CTRL-Z

You will get control back to bash. Then type (without the $):

$ fg

And this will go back into the process, and then quit out of Rails s properly.

It's a little annoying, but this sure beats killing the process manually. It's not too bad and it's the best I could figure out.

Updated answer:

You can use killall -9 rails to kill all running apps with "rails" in the name.

killall -9 rails

A simple solution is to use Microsoft ASP.NET Web API 2.2 Client from NuGet.

Then you can simply do this and it'll serialize the object to JSON and set the Content-Type header to application/json; charset=utf-8:

var data = new
{
    name = "Foo",
    category = "article"
};

var client = new HttpClient();
client.BaseAddress = new Uri(baseUri);
client.DefaultRequestHeaders.Add("token", token);
var response = await client.PostAsJsonAsync("", data);

An alternative approach would be to register an event handler on the pagination link like so:

$("#dataTableID_paginate").on("click", "a", function() { alert("clicked") });

Replace "#dataTableID_" with the ID of your table, of course. And I'm using JQuery's ON method as that is the current best practice.

Jupytext is nice to have in your toolchain for such conversions. It allows not only conversion from a notebook to a script, but you can go back again from the script to notebook as well. And even have that notebook produced in executed form.

jupytext --to py notebook.ipynb                 # convert notebook.ipynb to a .py file
jupytext --to notebook notebook.py              # convert notebook.py to an .ipynb file with no outputs
jupytext --to notebook --execute notebook.py    # convert notebook.py to an .ipynb file and run it

     new SelectListItem{Text="Deactive", Value="False"}})

$(':checkbox').change(function(){
    $('#delete').removeAttr('hidden');
});

Note, thanks to tip by A.Wolff, you should use removeAttr instead of setting to false. When set to false, the element will still be hidden. Therefore, removing is more effective.

This isn't as easy to do as one might expect -- you can really only do vertical alignment if you know the height of your container. IF this is the case, you can do it with absolute positioning.

The concept is to set the top / left positions at 50%, and then use negative margins (set to half the height / width) to pull the container back to being centered.

Example: http://jsbin.com/ipawe/edit

Basic CSS:

#mydiv { 
    position: absolute;
    top: 50%;
    left: 50%;
    height: 400px;
    width: 700px;
    margin-top: -200px; /* -(1/2 height) */
    margin-left: -350px; /* -(1/2 width) */
  }

You can use the button :

1 - make the text empty

2 - set the background for it

+3 - you can use the selector to more useful and nice button

About the imagebutton you can set the image source and the background the same picture and it must be (*.png) when you do it you can make any design for the button

and for more beauty button use the selector //just Google it ;)

Another programmatic Kotlin Alternative:

mButton.transformationMethod = null

public class One {

    private static One one = null;

    Map<String, String> configParameter = Collections.synchronizedMap(new HashMap<String, String>());

    private One() {
        ResourceBundle rb = ResourceBundle.getBundle("System", Locale.getDefault());

        Enumeration en = rb.getKeys();
        while (en.hasMoreElements()) {
            String key = (String) en.nextElement();
            String value = rb.getString(key);
            configParameter.put(key, value);

        }
    }

    public static One getInstance() {
        if (one == null) {
            one= new One();
        }

        return one;

    }

    public Map<String, String> getParameter() {

        return configParameter;
    }



    public static void main(String[] args) {
        String string = One.getInstance().getParameter().get("subin");
        System.out.println(string);

    }
}

You can use NSArray as

NSString *string1=@"This"

NSString *string2=@"is just"

NSString *string3=@"a test"  

NSArray *myStrings = [[NSArray alloc] initWithObjects:string1, string2, string3,nil];

NSString *fullLengthString = [myStrings componentsJoinedByString:@" "];

or

you can use

NSString *imageFullName=[NSString stringWithFormat:@"%@ %@ %@.", string1,string2,string3];

1 and 2 are SAML 1.1 because those URIs were part of the OASIS SAML 1.1 standard. Section 8.3 of the linked PDF for the OASIS SAML 2.0 standard explains this:

Where possible an existing URN is used to specify a protocol. In the case of IETF protocols, the URN of the most current RFC that specifies the protocol is used. URI references created specifically for SAML have one of the following stems, according to the specification set version in which they were first introduced:

urn:oasis:names:tc:SAML:1.0:
urn:oasis:names:tc:SAML:1.1:
urn:oasis:names:tc:SAML:2.0:

How about this?

for item in mylist:
    if item in checklist:
        pass
    else:
       # do something
       print item

Code :

var now = new Date();
var time = now.getTime();
time += 3600 * 1000;
now.setTime(time);
document.cookie = 
'username=' + value + 
'; expires=' + now.toUTCString() + 
'; path=/';

You'll want to convert the image to a byte[] in C#, and then you'll have the database column as varbinary(MAX)

After that, it's just like saving any other data type.

Looks like the type is boolean and therefore can never be null and should be false by default.

No need to find. If you are just looking for a pattern within a specific directory, this should suffice:

grep -hn FOO /your/path/*.bar

Where -h is the parameter to hide the filename, as from man grep:

-h, --no-filename

Suppress the prefixing of file names on output. This is the default when there is only one file (or only standard input) to search.

Note that you were using

-H, --with-filename

Print the file name for each match. This is the default when there is more than one file to search.

Now there are a lot of cloud providers , providing solutions like MBaaS (Mobile Backend as a Service). Some only give access to cloud database, some will do the user management for you, some let you place code around cloud database and there are facilities of access control, push notifications, analytics, integrated image and file hosting etc.

Here are some providers which have a "free-tier" (may change in future):

1. Firebase (Google) - https://firebase.google.com/
2. AWS Mobile (Amazon) - https://aws.amazon.com/mobile/
3. Azure Mobile (Microsoft) - https://azure.microsoft.com/en-in/services/app-service/mobile/
4. MongoDB Realm (MongoDB) - https://www.mongodb.com/realm
5. Back4app (Popular) - https://www.back4app.com/

Open source solutions:

1. Parse - http://parseplatform.org/
2. Apache User Grid - https://usergrid.apache.org/
3. SupaBase (under development) - https://supabase.io/

document.getElementById('myframe1').contentWindow.document.getElementById('x')

Fiddle

contentWindow is supported by all browsers including the older versions of IE.

Note that if the iframe's src is from another domain, you won't be able to access its content due to the Same Origin Policy.

You need to call the AddAddress function once for each E-Mail address you want to send to. There are only two arguments for this function: recipient_email_address and recipient_name. The recipient name is optional and will not be used if not present.

$mailer->AddAddress('[email protected]', 'First Name');
$mailer->AddAddress('[email protected]', 'Second Name');
$mailer->AddAddress('[email protected]', 'Third Name');

You could use an array to store the recipients and then use a for loop. I hope it helps.

You can with flexbox:

ul.list {
    padding: 0;
    list-style: none;
    display: flex;
    align-items: stretch;
    justify-items: center;
    flex-wrap: wrap;
    justify-content: center;
}
li {
    width: 100px;
    padding: .5rem;
    border-radius: 1rem;
    background: yellow;
    margin: 0 5px;
}

<ul class="list">
  <li>title 1</li>
  <li>title 2<br>new line</li>
  <li>title 3<br>new<br>line</li>
</ul>

This could be one solution.

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

case the column isn't string, use astype to convert:

df['col'] = df['col'].astype(str).str[:9]

On MySQL 5.1.51, both queries have identical execution plans:

mysql> explain select * from table1 a inner join table2 b on a.pid = b.pid;
+----+-------------+-------+------+---------------+------+---------+--------------+------+-------+
| id | select_type | table | type | possible_keys | key  | key_len | ref          | rows | Extra |
+----+-------------+-------+------+---------------+------+---------+--------------+------+-------+
|  1 | SIMPLE      | b     | ALL  | PRIMARY       | NULL | NULL    | NULL         |  986 |       |
|  1 | SIMPLE      | a     | ref  | pid           | pid  | 4       | schema.b.pid |   70 |       |
+----+-------------+-------+------+---------------+------+---------+--------------+------+-------+
2 rows in set (0.02 sec)

mysql> explain select * from table1 a, table2 b where a.pid = b.pid;
+----+-------------+-------+------+---------------+------+---------+--------------+------+-------+
| id | select_type | table | type | possible_keys | key  | key_len | ref          | rows | Extra |

+----+-------------+-------+------+---------------+------+---------+--------------+------+-------+
2 rows in set (0.00 sec)

table1 has 166208 rows; table2 has about 1000 rows.

This is a very simple case; it doesn't by any means prove that the query optimizer wouldn't get confused and generate different plans in a more complicated case.

^{Tip of the hat to @gniourf_gniourf for clearing up a fundamental misconception.}

This answer attempts to provide an overview of the existing answers and to discuss their subtleties and relative merits as well as to provide background information, especially with respect to portability.

Finding files that are executable can refer to two distinct use cases:

• user-centric: find files that are executable by the current user.
• file-centric: find files that have (one or more) executable permission bits set.

Note that in either scenario it may make sense to use find -L ... instead of just find ... in order to also find symlinks to executables.

Note that the simplest file-centric case - looking for executables with the executable permissions bit set for ALL three security principals (user, group, other) - will typically, but not necessarily yield the same results as the user-centric scenario - and it's important to understand the difference.

User-centric (-executable)

• The accepted answer commendably recommends -executable, IF GNU find is available.

  • GNU find comes with most Linux distros
    • By contrast, BSD-based platforms, including macOS, come with BSD find, which is less powerful.
  • As the scenario demands, -executable matches only files the current user can execute (there are edge cases.^[1]).

• The BSD find alternative offered by the accepted answer (-perm +111) answers a different, file-centric question (as the answer itself states).

  • Using just -perm to answer the user-centric question is impossible, because what is needed is to relate the file's user and group identity to the current user's, whereas -perm can only test the file's permissions.
    Using only POSIX find features, the question cannot be answered without involving external utilities.

  • Thus, the best -perm can do (by itself) is an approximation of -executable. Perhaps a closer approximation than -perm +111 is -perm -111, so as to find files that have the executable bit set for ALL security principals (user, group, other) - this strikes me as the typical real-world scenario. As a bonus, it also happens to be POSIX-compliant (use find -L to include symlinks, see farther below for an explanation):

    find . -type f -perm -111  # or: find . -type f -perm -a=x
    

• gniourf_gniourf's answer provides a true, portable equivalent of -executable, using -exec test -x {} \;, albeit at the expense of performance.

  • Combining -exec test -x {} \; with -perm +111 (i.e., files with at least one executable bit set) may help performance in that exec needn't be invoked for every file (the following uses the POSIX-compliant equivalent of BSD find -perm +111 / GNU find -perm /111; see farther below for an explanation):

    find . -type f \( -perm -u=x -o -perm -g=x -o -perm -o=x \) -exec test -x {} \; -print
    

File-centric (-perm)

• To answer file-centric questions, it is sufficient to use the POSIX-compliant -perm primary (known as a test in GNU find terminology).
  • -perm allows you to test for any file permissions, not just executability.
  • Permissions are specified as either octal or symbolic modes. Octal modes are octal numbers (e.g., 111), whereas symbolic modes are strings (e.g., a=x).
  • Symbolic modes identify the security principals as u (user), g (group) and o (other), or a to refer to all three. Permissions are expressed as x for executable, for instance, and assigned to principals using operators =, + and -; for a full discussion, including of octal modes, see the POSIX spec for the chmod utility.
  • In the context of find:
    • Prefixing a mode with - (e.g., -ug=x) means: match files that have all the permissions specified (but matching files may have additional permissions).
    • Having NO prefix (e.g. 755) means: match files that have this full, exact set of permissions.
    • Caveat: Both GNU find and BSD find implement an additional, nonstandard prefix with are-ANY-of-the-specified-permission-bits-set logic, but do so with incompatible syntax:
      • BSD find: +
      • GNU find: / ^[2]
    • Therefore, avoid these extensions, if your code must be portable.
• The examples below demonstrate portable answers to various file-centric questions.

File-centric command examples

Note:

• The following examples are POSIX-compliant, meaning they should work in any POSIX-compatible implementation, including GNU find and BSD find; specifically, this requires:
  • NOT using nonstandard mode prefixes + or /.
  • Using the POSIX forms of the logical-operator primaries:
    • ! for NOT (GNU find and BSD find also allow -not); note that \! is used in the examples so as to protect ! from shell history expansions
    • -a for AND (GNU find and BSD find also allow -and)
    • -o for OR (GNU find and BSD find also allow -or)
• The examples use symbolic modes, because they're easier to read and remember.
  • With mode prefix -, the = and + operators can be used interchangeably (e.g., -u=x is equivalent to -u+x - unless you apply -x later, but there's no point in doing that).
  • Use , to join partial modes; AND logic is implied; e.g., -u=x,g=x means that both the user and the group executable bit must be set.
  • Modes cannot themselves express negative matching in the sense of "match only if this bit is NOT set"; you must use a separate -perm expression with the NOT primary, !.
• Note that find's primaries (such as -print, or -perm; also known as actions and tests in GNU find) are implicitly joined with -a (logical AND), and that -o and possibly parentheses (escaped as \( and \) for the shell) are needed to implement OR logic.
• find -L ... instead of just find ... is used in order to also match symlinks to executables
  • -L instructs find to evaluate the targets of symlinks instead of the symlinks themselves; therefore, without -L, -type f would ignore symlinks altogether.

# Match files that have ALL executable bits set - for ALL 3 security
# principals (u (user), g (group), o (others)) and are therefore executable
# by *anyone*.
# This is the typical case, and applies to executables in _system_ locations
# (e.g., /bin) and user-installed executables in _shared_ locations
# (e.g., /usr/local/bin), for instance. 
find -L . -type f -perm -a=x  # -a=x is the same as -ugo=x

# The POSIX-compliant equivalent of `-perm +111` from the accepted answer:
# Match files that have ANY executable bit set.
# Note the need to group the permission tests using parentheses.
find -L . -type f \( -perm -u=x -o -perm -g=x -o -perm -o=x \)

# A somewhat contrived example to demonstrate the use of a multi-principial
# mode (comma-separated clauses) and negation:
# Match files that have _both_ the user and group executable bit set, while
# also _not_ having the other executable bit set.
find -L . -type f -perm -u=x,g=x  \! -perm -o=x

^{[1] Description of -executable from man find as of GNU find 4.4.2:}

Matches files which are executable and directories which are searchable (in a file name resolution sense). This takes into account access control lists and other permissions artefacts which the -perm test ignores. This test makes use of the access(2) system call, and so can be fooled by NFS servers which do UID mapping (or root-squashing), since many systems implement access(2) in the client's kernel and so cannot make use of the UID mapping information held on the server. Because this test is based only on the result of the access(2) system call, there is no guarantee that a file for which this test succeeds can actually be executed.

^{[2] GNU find versions older than 4.5.12 also allowed prefix +, but this was first deprecated and eventually removed, because combining + with symbolic modes yields likely yields unexpected results due to being interpreted as an exact permissions mask. If you (a) run on a version before 4.5.12 and (b) restrict yourself to octal modes only, you could get away with using + with both GNU find and BSD find, but it's not a good idea.}

mysql -u <user> -p -e "select * from schema.table"

Use varchar instead of VAR_CHAR and omit the comma in the last line i.e.phone INT NOT NULL );. The last line during creating table is kept "comma free". Ex:- CREATE TABLE COMPUTER ( Model varchar(50) ); Here, since we have only one column ,that's why there is no comma used during entire code.

If You have a base class A and a derived class B, then You can do the following.

void wantAnA(A myA)
{
   // work with myA
}

B derived;
// work with the object "derived"
wantAnA(derived);

Now the method wantAnA needs a copy of derived. However, the object derived cannot be copied completely, as the class B could invent additional member variables which are not in its base class A.

Therefore, to call wantAnA, the compiler will "slice off" all additional members of the derived class. The result might be an object you did not want to create, because

• it may be incomplete,
• it behaves like an A-object (all special behaviour of the class B is lost).

break x if ((int)strcmp(y, "hello")) == 0

On some implementations gdb might not know the return type of strcmp. That means you would have to cast, otherwise it would always evaluate to true!

You can add a new Primary Key column to an existing table, which can have sequence numbers, using command:

ALTER TABLE mydb.mytable ADD pk_columnName INT IDENTITY

May be I come later to answer but right now I'm facing with this... if helps there are one more solution (the way i solved it).

    var query2 = (
    from users in Repo.T_Benutzer
    join mappings in Repo.T_Benutzer_Benutzergruppen on mappings.BEBG_BE equals users.BE_ID into tmpMapp
    join groups in Repo.T_Benutzergruppen on groups.ID equals mappings.BEBG_BG into tmpGroups
    from mappings in tmpMapp.DefaultIfEmpty()
    from groups in tmpGroups.DefaultIfEmpty()
    select new
    {
         UserId = users.BE_ID
        ,UserName = users.BE_User
        ,UserGroupId = mappings.BEBG_BG
        ,GroupName = groups.Name
    }

);

By the way, I tried using the Stefan Steiger code which also helps but it was slower as hell.

Name = editTextName.getText().toString().trim();
Email = editTextEmail.getText().toString().trim();
Phone = editTextMobile.getText().toString().trim();


JSONArray jsonArray = new JSONArray();
jsonArray.put(Name);
jsonArray.put(Email);
jsonArray.put(Phone);
final String mRequestBody = jsonArray.toString();

StringRequest stringRequest = new StringRequest(Request.Method.PUT, OTP_Url, new Response.Listener<String>() {
    @Override
    public void onResponse(String response) {
        Log.v("LOG_VOLLEY", response);

    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        Log.e("LOG_VOLLEY", error.toString());
    }
}) {
    @Override
    public String getBodyContentType() {
        return "application/json; charset=utf-8";
    }

    @Override
    public byte[] getBody() throws AuthFailureError {
        try {
            return mRequestBody == null ? null : mRequestBody.getBytes("utf-8");
        } catch (UnsupportedEncodingException uee) {
            VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", mRequestBody, "utf-8");
            return null;
        }
    }

};
stringRequest.setShouldCache(false);
VollySupport.getmInstance(RegisterActivity.this).addToRequestque(stringRequest);

Use the following,

echo "<script type='text/javascript'> window.location.href = '$file_name'; </script>";

final means that the value cannot be changed after initialization, that's what makes it a constant. static means that instead of having space allocated for the field in each object, only one instance is created for the class.

So, static final means only one instance of the variable no matter how many objects are created and the value of that variable can never change.

try this

var json = [{
    "id" : "1", 
    "msg"   : "hi",
    "tid" : "2013-05-05 23:35",
    "fromWho": "[email protected]"
},
{
    "id" : "2", 
    "msg"   : "there",
    "tid" : "2013-05-05 23:45",
    "fromWho": "[email protected]"
}];

json.forEach((item) => {
  console.log('ID: ' + item.id);
  console.log('MSG: ' + item.msg);
  console.log('TID: ' + item.tid);
  console.log('FROMWHO: ' + item.fromWho);
});

Late to the game, but most of these seem quite complicated.

Here's how I did it:

var originalSelect = $('#select-2').html();

// filter select-2 on select-1 change
$('#select-1').change(function (e) {

    var selected = $(this).val();

    // reset select ready for filtering
    $('#select-2').html(originalCourseSelect);

    if (selected) {
        // filter
        $('#select-2 option').not('.t' + selected).remove();
    }

});

markup of select-1:

<select id='select-1'>
<option value=''>Please select</option>
<option value='1'>One</option>
<option value='2'>Two</option>
</select>

markup of select-2:

<select id='select-2'>
<option class='t1'>One</option>
<option class='t2'>Two</option>
<option>Always visible</option>
</select>

You could use a variable to make the calculation and use toFixed when you set the #diskamountUnit element value:

var amount = $("#disk").slider("value") * 1.60;
$("#diskamountUnit").val('$' + amount.toFixed(2));

You can also do that in one step, in the val method call but IMO the first way is more readable:

$("#diskamountUnit").val('$' + ($("#disk").slider("value") * 1.60).toFixed(2));

This expands on a previous answer. The best solution I've found is to make an innocuous CSS attribute that only appears if a CSS3 media query is met, and then have the JS test for that attribute.

So for instance, in the CSS you'd have:

@media screen only and (orientation:landscape)
{
    //  Some innocuous rule here
    body
    {
        background-color: #fffffe;
    }
}
@media screen only and (orientation:portrait)
{
    //  Some innocuous rule here
    body
    {
        background-color: #fffeff;
    }
}

You then go to JavaScript (I'm using jQuery for funsies). Color declarations may be weird, so you may want to use something else, but this is the most foolproof method I've found for testing it. You can then just use the resize event to pick up on switching. Put it all together for:

function detectOrientation(){
    //  Referencing the CSS rules here.
    //  Change your attributes and values to match what you have set up.
    var bodyColor = $("body").css("background-color");
    if (bodyColor == "#fffffe") {
        return "landscape";
    } else
    if (bodyColor == "#fffeff") {
        return "portrait";
    }
}
$(document).ready(function(){
    var orientation = detectOrientation();
    alert("Your orientation is " + orientation + "!");
    $(document).resize(function(){
        orientation = detectOrientation();
        alert("Your orientation is " + orientation + "!");
    });
});

The best part of this is that as of my writing this answer, it doesn't appear to have any effect on desktop interfaces, since they (generally) don't (seem to) pass any argument for orientation to the page.

check whether you import FormsModule. There's no ngControl in the new forms angular 2 release version. you have to change your template to as an example

<div class="row">
    <div class="form-group col-sm-7 col-md-5">
        <label for="name">Name</label>
        <input type="text" class="form-control" required
               [(ngModel)]="user.name"
               name="name" #name="ngModel">
        <div [hidden]="name.valid || name.pristine" class="alert alert-danger">
            Name is required
        </div>
    </div>
</div>

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html> 

IF your data won't overflow 4000 characters AND you're on SQL Server 2000 or compatibility level of 8 or SQL Server 2000:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(4000)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

For SQL Server 2005+:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(MAX)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

Try:

Exception.Message contains only the message (doh) associated with the exception. Example:

Object reference not set to an instance of an object

The Exception.ToString() method will give a much more verbose output, containing the exception type, the message (from before), a stack trace, and all of these things again for nested/inner exceptions. More precisely, the method returns the following:

ToString returns a representation of the current exception that is intended to be understood by humans. Where the exception contains culture-sensitive data, the string representation returned by ToString is required to take into account the current system culture. Although there are no exact requirements for the format of the returned string, it should attempt to reflect the value of the object as perceived by the user.

The default implementation of ToString obtains the name of the class that threw the current exception, the message, the result of calling ToString on the inner exception, and the result of calling Environment.StackTrace. If any of these members is a null reference (Nothing in Visual Basic), its value is not included in the returned string.

If there is no error message or if it is an empty string (""), then no error message is returned. The name of the inner exception and the stack trace are returned only if they are not a null reference (Nothing in Visual Basic).

I used read_csv from the readr package

In my experience, the parameter row.names=NULL in the read.csv function will lead to a wrong reading of the file if a column name is missing, i.e. every column will be shifted.

read_csv solves this.

In case you can't upgrade to Ruby on Rails 2.3.11 (and to expand on douglasr's answer), thread must be required at the top of boot.rb. For example:

require 'thread'

# Don't change this file!
# Configure your app in config/environment.rb and config/environments/*.rb
...

You can easily import your model and run this:

from models import User

# User is the name of table that has a column name
users = User.query.all()

for user in users:
    print user.name

Since Java 8, it seems like the java.time standard library is the way to go. From Joda time web page:

Note that from Java SE 8 onwards, users are asked to migrate to java.time (JSR-310) - a core part of the JDK which replaces this project.

Back to your question. Were you to use Java 8, I think you want LocalDateTime. Because it contains the date and time-of-the-day, but is unaware of time zone or any reference point in time such as the unix epoch.

For mac users

First Try : go to activity monitor -> search for java and kill the instance then restart the server and try.

Second Try: Check log file for any errors under tomcat logs folder.

Use below command to check tomcat logs in terminal

tail -f {tomcatpath}/logs/catalina.out

Third Try: Check if node or other apps using the same port. Use below command to check which app listening to a specific port. You will see list of apps with pid in second column.

lsof -i :8080 | grep LISTEN

Kill the process using below command

sudo kill -9 pid

I understand/hope that the lists have the same length: No, your only bet is going with a plain old standard for loop.

The R in REST stands for resource

(Which isn't true, because it stands for Representational, but it's a good trick to remember the importance of Resources in REST).

About PUT /groups/api/v1/groups/{group id}/status/activate: you are not updating an "activate". An "activate" is not a thing, it's a verb. Verbs are never good resources. A rule of thumb: if the action, a verb, is in the URL, it probably is not RESTful.

What are you doing instead? Either you are "adding", "removing" or "updating" an activation on a Group, or if you prefer: manipulating a "status"-resource on a Group. Personally, I'd use "activations" because they are less ambiguous than the concept "status": creating a status is ambiguous, creating an activation is not.

• POST /groups/{group id}/activation Creates (or requests the creation of) an activation.
• PATCH /groups/{group id}/activation Updates some details of an existing activation. Since a group has only one activation, we know what activation-resource we are referring to.
• PUT /groups/{group id}/activation Inserts-or-replaces the old activation. Since a group has only one activation, we know what activation-resource we are referring to.
• DELETE /groups/{group id}/activation Will cancel, or remove the activation.

This pattern is useful when the "activation" of a Group has side-effects, such as payments being made, mails being sent and so on. Only POST and PATCH may have such side-effects. When e.g. a deletion of an activation needs to, say, notify users over mail, DELETE is not the right choice; in that case you probably want to create a deactivation resource: POST /groups/{group_id}/deactivation.

It is a good idea to follow these guidelines, because this standard contract makes it very clear for your clients, and all the proxies and layers between the client and you, know when it is safe to retry, and when not. Let's say the client is somewhere with flaky wifi, and its user clicks on "deactivate", which triggers a DELETE: If that fails, the client can simply retry, until it gets a 404, 200 or anything else it can handle. But if it triggers a POST to deactivation it knows not to retry: the POST implies this.
Any client now has a contract, which, when followed, will protect against sending out 42 emails "your group has been deactivated", simply because its HTTP-library kept retrying the call to the backend.

Updating a single attribute: use PATCH

PATCH /groups/{group id}

In case you wish to update an attribute. E.g. the "status" could be an attribute on Groups that can be set. An attribute such as "status" is often a good candidate to limit to a whitelist of values. Examples use some undefined JSON-scheme:

PATCH /groups/{group id} { "attributes": { "status": "active" } }
response: 200 OK

PATCH /groups/{group id} { "attributes": { "status": "deleted" } }
response: 406 Not Acceptable

Replacing the resource, without side-effects use PUT.

PUT /groups/{group id}

In case you wish to replace an entire Group. This does not necessarily mean that the server actually creates a new group and throws the old one out, e.g. the ids might remain the same. But for the clients, this is what PUT can mean: the client should assume he gets an entirely new item, based on the server's response.

The client should, in case of a PUT request, always send the entire resource, having all the data that is needed to create a new item: usually the same data as a POST-create would require.

PUT /groups/{group id} { "attributes": { "status": "active" } }
response: 406 Not Acceptable

PUT /groups/{group id} { "attributes": { "name": .... etc. "status": "active" } }
response: 201 Created or 200 OK, depending on whether we made a new one.

A very important requirement is that PUT is idempotent: if you require side-effects when updating a Group (or changing an activation), you should use PATCH. So, when the update results in e.g. sending out a mail, don't use PUT.

Following up on sas's answer, PHP 5.4, Symfony 2.8, I had to use

ini_set('date.timezone','<whatever timezone string>');

instead of date_default_timezone_set. I also added a call to ini_set to the top of a custom web/config.php to get that check to succeed.

Be very careful: NULL is a macro used mainly for pointers. The standard way of terminating a string is:

char *buffer;
...
buffer[end_position] = '\0';

This (below) works also but it is not a big difference between assigning an integer value to a int/short/long array and assigning a character value. This is why the first version is preferred and personally I like it better.

buffer[end_position] = 0; 

View rootLayout = view.getRootView().findViewById(android.R.id.content);

int[] viewLocation = new int[2]; 
view.getLocationInWindow(viewLocation);

int[] rootLocation = new int[2];
rootLayout.getLocationInWindow(rootLocation);

int relativeLeft = viewLocation[0] - rootLocation[0];
int relativeTop  = viewLocation[1] - rootLocation[1];

First I get the root layout then calculate the coordinates difference with the view.
You can also use the getLocationOnScreen() instead of getLocationInWindow().

I had this problem despite:

• having a main(); and
• configuring all other projects in my solution to be static libraries.

My eventual fix was the following:

• my main() was in a namespace, so was effectively called something::main() ...removing this namespace fixed the problem.

Windows Forms (and its visual designer) have been available for .NET Core (as a preview) since Visual Studio 2019 16.6. It's quite good, although sometimes I need to open Visual Studio 2019 16.7 Preview to get around annoying bugs.

See this blog post: Windows Forms Designer for .NET Core Released

Also, Windows Forms is now open source: https://github.com/dotnet/winforms

I know you are long past getting a solution. So, this is for others that come along to see how other people are solving the same common problem-- like me.

The examples in the question and answers indicates the use of jQuery and I am using the .change listener/handler/whatever to see if my textarea changes. This should take care of manual text changes, automated text changes, etc. to trigger the

//pseudocode
$(document).ready(function () {
    $('#textarea').change(function () {
        if ($.trim($('#textarea').val()).length < 1) {

            $('#output').html('Someway your box is being reported as empty... sadness.');

        } else {

            $('#output').html('Your users managed to put something in the box!');
            //No guarantee it isn't mindless gibberish, sorry.

        }
    });
});

Seems to work on all the browsers I use. http://jsfiddle.net/Q3LW6/. Message shows when textarea loses focus.

Newer, more thorough example: https://jsfiddle.net/BradChesney79/tjj6338a/

Uses and reports .change(), .blur(), .keydown(), .keyup(), .mousedown(), .mouseup(), .click(), mouseleave(), and .setInterval().
