You can use the curses.h library in linux as mentioned in the other answer.

You can install it in Ubuntu by:

sudo apt-get update

sudo apt-get install ncurses-dev

I took the installation part from here.

you can try this (I don't have sql server here today so I can't verify syntax, sorry)

select attributeName
  from tableName
 where CONVERT(varchar,attributeName,101) BETWEEN '03/01/2009' AND '03/31/2009'
   and CONVERT(varchar, attributeName,108) BETWEEN '06:00:00' AND '22:00:00'
   and DATEPART(day,attributeName) BETWEEN 2 AND 4

Check out Joda, which simplifies date/time calculations (Joda is also the basis of the new standard Java date/time apis, so you'll be learning a soon-to-be-standard API).

EDIT: Java 8 has something very similar and is worth checking out.

e.g.

LocalDate birthdate = new LocalDate (1970, 1, 20);
LocalDate now = new LocalDate();
Years age = Years.yearsBetween(birthdate, now);

which is as simple as you could want. The pre-Java 8 stuff is (as you've identified) somewhat unintuitive.

My scenario is < CustomBoladonesTextInput /> wrapping a RN < TextInput />.

I solved this issue as follow:

My form looks like:

  <CustomBoladonesTextInput 
      onSubmitEditing={() => this.customInput2.refs.innerTextInput2.focus()}
      returnKeyType="next"
      ... />

  <CustomBoladonesTextInput 
       ref={ref => this.customInput2 = ref}
       refInner="innerTextInput2"
       ... />

On CustomBoladonesTextInput's component definition, I pass the refField to the inner ref prop like this:

   export default class CustomBoladonesTextInput extends React.Component {
      render() {        
         return (< TextInput ref={this.props.refInner} ... />);     
      } 
   }

And voila. Everything get back works again. Hope this helps

Try

git add -u

The "u" option stands for update. This will update the repo and actually delete files from the repo that you have deleted in your local copy.

git add -u [filename]

to stage a delete to just one file. Once pushed, the file will no longer be in the repo.

Alternatively,

git add -A .

is equivalent to

git add .

git add -u .

Note the extra '.' on git add -A and git add -u

Warning: Starting with git 2.0 (mid 2013), this will always stage files on the whole working tree.
If you want to stage files under the current path of your working tree, you need to use:

git add -A .

Also see: Difference of git add -A and git add .

you can use .parseXML

var xml='<Pages>
          <Page Name="test">
           <controls>
              <test>this is a test.</test>
           </controls>  
          </Page>
          <page Name = "User">

reference answer: relative path in BAT script

Wikipedia Says:

MinGW forked from version 1.3.3 of Cygwin. Although both Cygwin and MinGW can be used to port UNIX software to Windows, they have different approaches: Cygwin aims to provide a complete POSIX layer that provides emulations of several system calls and libraries that exist on Linux, UNIX, and the BSD variants. The POSIX layer runs on top of Windows, sacrificing performance where necessary for compatibility. Accordingly, this approach requires Windows programs written with Cygwin to run on top of a copylefted compatibility library that must be distributed with the program, along with the program's source code. MinGW aims to provide native functionality and performance via direct Windows API calls. Unlike Cygwin, MinGW does not require a compatibility layer DLL and thus programs do not need to be distributed with source code.

Because MinGW is dependent upon Windows API calls, it cannot provide a full POSIX API; it is unable to compile some UNIX applications that can be compiled with Cygwin. Specifically, this applies to applications that require POSIX functionality like fork(), mmap() or ioctl() and those that expect to be run in a POSIX environment. Applications written using a cross-platform library that has itself been ported to MinGW, such as SDL, wxWidgets, Qt, or GTK+, will usually compile as easily in MinGW as they would in Cygwin.

The combination of MinGW and MSYS provides a small, self-contained environment that can be loaded onto removable media without leaving entries in the registry or files on the computer. Cygwin Portable provides a similar feature. By providing more functionality, Cygwin becomes more complicated to install and maintain.

It is also possible to cross-compile Windows applications with MinGW-GCC under POSIX systems. This means that developers do not need a Windows installation with MSYS to compile software that will run on Windows without Cygwin.

Meaning.

In brief, $@ expands to the positional arguments passed from the caller to either a function or a script. Its meaning is context-dependent: Inside a function, it expands to the arguments passed to such function. If used in a script (not inside the scope a function), it expands to the arguments passed to such script.

$ cat my-sh
#! /bin/sh
echo "$@"

$ ./my-sh "Hi!"
Hi!

$ put () ( echo "$@" )
$ put "Hi!"
Hi!

Word splitting.

Now, another topic that is of paramount importance when understanding how $@ behaves in the shell is word splitting. The shell splits tokens based on the contents of the IFS variable. Its default value is \t\n; i.e., whitespace, tab, and newline.

Expanding "$@" gives you a pristine copy of the arguments passed. However, expanding $@ will not always. More specifically, if the arguments contain characters from IFS, they will split.

Most of the time what you will want to use is "$@", not $@.

By the RFC7231 it does not matter and may be empty

How we implement json api standard based solution in the project:

post/put: outputs object attributes as in get (field filter/relations applies the same)

delete: data only contains null (for its a representation of missing object)

status for standard delete: 200

I have defined this:

if (PHP_SAPI === 'cli')
{
   define( "LNBR", PHP_EOL);
}
else
{
   define( "LNBR", "<BR/>");
}

After this use LNBR wherever I want to use \n.

You should be using a Property:

Private _myValue As String
Public Property MyValue As String
    Get
        Return _myValue
    End Get
    Set(value As String)
        _myValue = value
     End Set
End Property

Then use it like so:

MyValue = "Hello"
Console.write(MyValue)

The following works perfectly for me.

First set your date picker widget's input to 'none' to prevent the soft keyboard from popping up:

<EditText android:inputType="none" ... ></EditText>

Then add these event listeners to show the dialog containing the date picker:

// Date picker
EditText dateEdit = (EditText) findViewById(R.id.date);
dateOfBirthEdit.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            showDialog(DIALOG_DATE_PICKER);
        }
        return false;
    }
});

dateEdit.setOnFocusChangeListener(new OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus) {
            showDialog(DIALOG_DATE_PICKER);
        } else {
            dismissDialog(DIALOG_DATE_PICKER);
        }
    }
});

One last thing. To make sure typed days, months, or years are correctly copied from the date picker, call datePicker.clearFocus() before retrieving the values, for instance via getMonth().

I had the following error when removing a dead container (docker 17.06.1-ce on CentOS 7):

Error response from daemon: driver "overlay" failed to remove root filesystem for <some-id>: 
remove /var/lib/docker/overlay/<some-id>/merged: device or resource busy

Here is how I fixed it:

1. Check which other processes are also using docker resources

$ grep docker /proc/*/mountinfo

which outputs something like this, where the number after /proc/ is the pid:

/proc/10001/mountinfo:179...
/proc/10002/mountinfo:149...
/proc/12345/mountinfo:159 149 0:36 / /var/lib/docker/overlay/...

2. Check the process name of the above pid

$ ps -p 10001 -o comm=
dockerd
$ ps -p 10002 -o comm=
docker-containe
$ ps -p 12345 -o comm=
nginx   <<<-- This is suspicious!!!

So, nginx with pid 12345 seems to also be using /var/lib/docker/overlay/..., which is why we cannot remove the related container and get the device or resource busy error. (See here for a discussion on how nginx shares the same mount namespace with docker containers thus prevents its deletion.)

3. Stop nginx and then I can remove the container successfully.

$ sudo service nginx stop
$ docker rm <container-id>

When you send bytes from a buffer with a normal TCP socket, the send function returns the number of bytes of the buffer that were sent. If it is a non-blocking socket or a non-blocking send then the number of bytes sent may be less than the size of the buffer. If it is a blocking socket or blocking send, then the number returned will match the size of the buffer but the call may block. With WebSockets, the data that is passed to the send method is always either sent as a whole "message" or not at all. Also, browser WebSocket implementations do not block on the send call.

But there are more important differences on the receiving side of things. When the receiver does a recv (or read) on a TCP socket, there is no guarantee that the number of bytes returned corresponds to a single send (or write) on the sender side. It might be the same, it may be less (or zero) and it might even be more (in which case bytes from multiple send/writes are received). With WebSockets, the recipient of a message is event-driven (you generally register a message handler routine), and the data in the event is always the entire message that the other side sent.

Note that you can do message based communication using TCP sockets, but you need some extra layer/encapsulation that is adding framing/message boundary data to the messages so that the original messages can be re-assembled from the pieces. In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message. The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message.

I simply did:

quit();

REASON WHY THIS HAPPENS (EXPLANATION)

suppose we have 2 tables users and subscription.

1 user has 1 subscription

IN USER MODEL, we have

public function subscription()
{
    return $this->hasOne('App\Subscription','user_id');
}

we can access subscription details as follows

$users = User:all();

foreach($users as $user){
    echo $user->subscription;
}

if any of the user does not have a subscription, which can be a case. we cannot use arrow function further after subscription like below

$user->subscription->abc   [this will not work] 
$user->subscription['abc']  [this will work]

but if the user has a subscription

$user->subscription->abc   [this will work] 

NOTE: try putting a if condition like this

if($user->subscription){
 return $user->subscription->abc;
}

Just follow this order

You can center any number of child in a FrameLayout.

<FrameLayout
    >
    <child1
        ....
        android:layout_gravity="center"
        .....
        />
    <Child2
        ....
        android:layout_gravity="center"
        />
</FrameLayout>

So the key is

adding android:layout_gravity="center"in the child views.

For example:

I centered a CustomView and a TextView on a FrameLayout like this

Code:

<FrameLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
    <com.airbnb.lottie.LottieAnimationView
        android:layout_width="180dp"
        android:layout_height="180dp"
        android:layout_gravity="center"
        app:lottie_fileName="red_scan.json"
        app:lottie_autoPlay="true"
        app:lottie_loop="true" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:textColor="#ffffff"
        android:textSize="10dp"
        android:textStyle="bold"
        android:padding="10dp"
        android:text="Networks Available: 1\n click to see all"
        android:gravity="center" />
</FrameLayout>

Result:

There are commercial products such as ionCube (which I use), source guardian, and Zen Guard.

There are also postings on the net which claim they can reverse engineer the encoded programs. How reliable they are is questionable, since I have never used them.

Note that most of these solutions require an encoder to be installed on their servers. So you may want to make sure your client is comfortable with that.

np.random.random_sample(size) will generate random floats in the half-open interval [0.0, 1.0).

For the final, compiled code of your application, the short answer is “no”. Different tools are able to extract different information from the code (e.g. the forms setups) and there are P code decompilers (see Edgar's excellent link for such tools). However, up to this day, there is no decompiler for native code. I'm not aware of anything similar for other high-level languages either.

First is latitude, second longitude. Different than many constructors in mapbox.

Here are examples of formats that work:

• Degrees, minutes, and seconds (DMS): 41°24'12.2"N 2°10'26.5"E
• Degrees and decimal minutes (DMM): 41 24.2028, 2 10.4418
• Decimal degrees (DD): 41.40338, 2.17403

Tips for formatting your coordinates

• Use the degree symbol instead of “d”.
• Use periods as decimals, not commas.
  • Incorrect: 41,40338, 2,17403.
  • Correct: 41.40338, 2.17403.
• List your latitude coordinates before longitude coordinates.
• Check that the first number in your latitude coordinate is between -90 and 90 and the first number in your longitude coordinate is between -180 and 180.

This is from http://www.acm.uiuc.edu/webmonkeys/book/c_guide/2.13.html#rand:

Declaration:

void srand(unsigned int seed); 

This function seeds the random number generator used by the function rand. Seeding srand with the same seed will cause rand to return the same sequence of pseudo-random numbers. If srand is not called, rand acts as if srand(1) has been called.

For any case set overflow-x to hidden and I prefer to set max-height in order to limit the expansion of the height of the div. Your code should looks like this:

overflow-y: scroll;
overflow-x: hidden;
max-height: 450px;

xcopy "$(ProjectDir)Views\Home\Index.cshtml" "$(SolutionDir)MEFMVCPOC\Views\Home"

and if you want to copy entire folders:

xcopy /E /Y "$(ProjectDir)Views" "$(SolutionDir)MEFMVCPOC\Views"

Update: here's the working version

xcopy "$(ProjectDir)Views\ModuleAHome\Index.cshtml" "$(SolutionDir)MEFMVCPOC\Views\ModuleAHome\" /Y /I

Here are some commonly used switches with xcopy:

• /I - treat as a directory if copying multiple files.
• /Q - Do not display the files being copied.
• /S - Copy subdirectories unless empty.
• /E - Copy empty subdirectories.
• /Y - Do not prompt for overwrite of existing files.
• /R - Overwrite read-only files.

My Spring Data JPA-based answer: I simply added a @Transactional annotation to my outer method.

Why it works

The child entity was immediately becoming detached because there was no active Hibernate Session context. Providing a Spring (Data JPA) transaction ensures a Hibernate Session is present.

Watch this video, I had the same question. He shows you how to debug the service as well.

Here are his instructions using the basic C# Windows Service template in Visual Studio 2010/2012.

You add this to the Service1.cs file:

public void onDebug()
{
    OnStart(null);
}

You change your Main() to call your service this way if you are in the DEBUG Active Solution Configuration.

static void Main()
{
    #if DEBUG
    //While debugging this section is used.
    Service1 myService = new Service1();
    myService.onDebug();
    System.Threading.Thread.Sleep(System.Threading.Timeout.Infinite);

    #else
    //In Release this section is used. This is the "normal" way.
    ServiceBase[] ServicesToRun;
    ServicesToRun = new ServiceBase[] 
    { 
        new Service1() 
    };
    ServiceBase.Run(ServicesToRun);
    #endif
}

Keep in mind that while this is an awesome way to debug your service. It doesn't call OnStop() unless you explicitly call it similar to the way we called OnStart(null) in the onDebug() function.

var fs = require("fs");
var filename = "./index.html";

function start(resp) {
    resp.writeHead(200, {
        "Content-Type": "text/html"
    });
    fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        resp.write(data);
        resp.end();
    });
}

Insert a column, for instance a new A column. Then use this function;

="k"&B1

and copy it down.

Then you can hide the new column A if you need too.

Try,

 # cat test.sh
 #!/bin/bash
 /bin/touch file.txt

cron as:

 * * * * * /bin/sh /home/myUser/scripts/test.sh

And you can confirm this by:

 # tailf /var/log/cron

I tried casting to a string and testing for a zero-length string and it worked.

   WHEN LEN(CAST(field_value AS VARCHAR(MAX))) = 0 THEN 
       DO THIS
END AS field 

Problem is your Xcode version is not set on Command Line Tools, to solve this problem open Xcode>Menu>preferences> location> here for Command Line tools select your Xcode version, that's it.

(This explanation is only for positive numbers since it depends on the language otherwise)

Definition

The Modulus is the remainder of the euclidean division of one number by another. % is called the modulo operation.

For instance, 9 divided by 4 equals 2 but it remains 1. Here, 9 / 4 = 2 and 9 % 4 = 1.

In your example: 5 divided by 7 gives 0 but it remains 5 (5 % 7 == 5).

Calculation

The modulo operation can be calculated using this equation:

a % b = a - floor(a / b) * b

• floor(a / b) represents the number of times you can divide a by b
• floor(a / b) * b is the amount that was successfully shared entirely
• The total (a) minus what was shared equals the remainder of the division

Applied to the last example, this gives:

5 % 7 = 5 - floor(5 / 7) * 7 = 5

Modular Arithmetic

That said, your intuition was that it could be -2 and not 5. Actually, in modular arithmetic, -2 = 5 (mod 7) because it exists k in Z such that 7k - 2 = 5.

You may not have learned modular arithmetic, but you have probably used angles and know that -90° is the same as 270° because it is modulo 360. It's similar, it wraps! So take a circle, and say that it's perimeter is 7. Then you read where is 5. And if you try with 10, it should be at 3 because 10 % 7 is 3.

Depending on the structure of the string, you can use lstrip:

str = str.lstrip(':')

But this would remove all colons at the beginning, i.e. if you have ::foo, the result would be foo. But this function is helpful if you also have strings that do not start with a colon and you don't want to remove the first character then.

You can't alter the existing columns for identity.

You have 2 options,

Create a new table with identity & drop the existing table

Create a new column with identity & drop the existing column

Approach 1. (New table) Here you can retain the existing data values on the newly created identity column.

CREATE TABLE dbo.Tmp_Names
    (
      Id int NOT NULL
             IDENTITY(1, 1),
      Name varchar(50) NULL
    )
ON  [PRIMARY]
go

SET IDENTITY_INSERT dbo.Tmp_Names ON
go

IF EXISTS ( SELECT  *
            FROM    dbo.Names ) 
    INSERT  INTO dbo.Tmp_Names ( Id, Name )
            SELECT  Id,
                    Name
            FROM    dbo.Names TABLOCKX
go

SET IDENTITY_INSERT dbo.Tmp_Names OFF
go

DROP TABLE dbo.Names
go

Exec sp_rename 'Tmp_Names', 'Names'

Approach 2 (New column) You can’t retain the existing data values on the newly created identity column, The identity column will hold the sequence of number.

Alter Table Names
Add Id_new Int Identity(1, 1)
Go

Alter Table Names Drop Column ID
Go

Exec sp_rename 'Names.Id_new', 'ID', 'Column'

I found

git diff <branch_with_changes> <branch_to_compare_to>

more useful, since you don't only get the commit messages but the whole diff. If you are already on the branch you want to see the changes of and (for instance) want to see what has changed to the master, you can use:

git diff HEAD master

Javadocs don't offer any special tools for external links, so you should just use standard html:

This is extension of answer provided by Ranjith

I would suggest, you to choose a choice-parameter build, and specify the branches that you would like to build. Active Choice Parameter

And after that, you can specify branches to build. Branch to Build

Now, when you would build your project, you would be provided with "Build with Parameters, where you can choose the branch to build"

You can also write a groovy script to fetch all your branches to in active choice parameter.

This worked for me. Special thanks to all the posts above. This should return a collection of all your models.

  models.push temp.last.gsub(/\.rb$/, '').camelize.constantize rescue nil

Here's an adaptation of CD Sanchez' answer that consistently returns a 6-digit colour code:

var stringToColour = function(str) {
  var hash = 0;
  for (var i = 0; i < str.length; i++) {
    hash = str.charCodeAt(i) + ((hash << 5) - hash);
  }
  var colour = '#';
  for (var i = 0; i < 3; i++) {
    var value = (hash >> (i * 8)) & 0xFF;
    colour += ('00' + value.toString(16)).substr(-2);
  }
  return colour;
}

Usage:

stringToColour("greenish");
// -> #9bc63b

Example:

http://jsfiddle.net/sUK45/

(An alternative/simpler solution might involve returning an 'rgb(...)'-style colour code.)

If you're instantiating an android.support.v4.app.Fragment class, the you have to call getActivity().getSupportFragmentManager() to get rid of the cannot-resolve problem. However the official Android docs on Fragment by Google tends to over look this simple problem and they still document it without the getActivity() prefix.

try $conn = mysql_connect("localhost", "root") or $conn = mysql_connect("localhost", "root", "")

Add these two file in your app.module.ts

import { FileTransfer } from '@ionic-native/file-transfer';
import { File } from '@ionic-native/file';

after that declare these to in provider..

providers: [

    Items,
    User,
    Camera,
    File,
    FileTransfer];

This is work for me.

I answered a very similar question:

You simply need to iterate over the series' .Points collection, and then you can assign the points' .Format.Fill.ForeColor.RGB value based on whatever criteria you need.

UPDATED

The code below will color the chart per the screenshot. This only assumes three colors are used. You can add additional case statements for other color values, and update the assignment of myColor to the appropriate RGB values for each.

Option Explicit
Sub ColorScatterPoints()
    Dim cht As Chart
    Dim srs As Series
    Dim pt As Point
    Dim p As Long
    Dim Vals$, lTrim#, rTrim#
    Dim valRange As Range, cl As Range
    Dim myColor As Long

    Set cht = ActiveSheet.ChartObjects(1).Chart
    Set srs = cht.SeriesCollection(1)

   '## Get the series Y-Values range address:
    lTrim = InStrRev(srs.Formula, ",", InStrRev(srs.Formula, ",") - 1, vbBinaryCompare) + 1
    rTrim = InStrRev(srs.Formula, ",")
    Vals = Mid(srs.Formula, lTrim, rTrim - lTrim)
    Set valRange = Range(Vals)

    For p = 1 To srs.Points.Count
        Set pt = srs.Points(p)
        Set cl = valRange(p).Offset(0, 1) '## assume color is in the next column.

        With pt.Format.Fill
            .Visible = msoTrue
            '.Solid  'I commented this out, but you can un-comment and it should still work
            '## Assign Long color value based on the cell value
            '## Add additional cases as needed.
            Select Case LCase(cl)
                Case "red"
                    myColor = RGB(255, 0, 0)
                Case "orange"
                    myColor = RGB(255, 192, 0)
                Case "green"
                    myColor = RGB(0, 255, 0)
            End Select

            .ForeColor.RGB = myColor

        End With
    Next


End Sub

If you move the files for whatever reason manually, then Elipse lost the reference and output a missing project file error, but the reason is thaty you move manually the files and Eclipse lost the reference

You can also use something like:

import pip

def install(package):
    if hasattr(pip, 'main'):
        pip.main(['install', package])
    else:
        pip._internal.main(['install', package])

# Example
if __name__ == '__main__':
    install('argh')

Within IntelliJ, open pom.xml file.

Add this section before <dependencies> (if your file already has a <properties> section, just add the <maven.compiler...> lines below to that existing section):

<properties> 
   <maven.compiler.source>1.8</maven.compiler.source> 
   <maven.compiler.target>1.8</maven.compiler.target> 
</properties>

Try to play with

setMinSize()
setMaxSize()
setPreferredSize()

These method are used by layout when it decide what should be the size of current element. The layout manager calls setSize() and actually overrides your values.

I think once you have isolated the domain name, say, using Erklan's idea:

$myUrl = "http://www.domain.com/link.php";
$myParsedURL = parse_url($myUrl);
$myDomainName= $myParsedURL['host'];

you could use :

if( false === filter_var( $myDomainName, FILTER_VALIDATE_URL ) ) {
// failed test

}

PHP5s Filter functions are for just such a purpose I would have thought.

It does not strictly answer your question as it does not use Regex, I realise.

I'd recommend you go with REST first - if you're using Java look at JAX-RS and the Jersey implementation. REST is much simpler and easy to interop in many languages.

As others have said in this thread, the problem with SOAP is its complexity when the other WS-* specifications come in and there are countless interop issues if you stray into the wrong parts of WSDL, XSDs, SOAP, WS-Addressing etc.

The best way to judge the REST v SOAP debate is look on the internet - pretty much all the big players in the web space, google, amazon, ebay, twitter et al - tend to use and prefer RESTful APIs over the SOAP ones.

The other nice approach to going with REST is that you can reuse lots of code and infratructure between a web application and a REST front end. e.g. rendering HTML versus XML versus JSON of your resources is normally pretty easy with frameworks like JAX-RS and implicit views - plus its easy to work with RESTful resources using a web browser

You can achieve this more universally by applying the following CSS:

html,
body {
  height: 100%;
  width: 100%;
  overflow: auto;
}

This allows your content, whatever it is, to become scrollable within body, but be aware that the scrolling context where scroll event is fired is now document.body, not window.

Simple solution stop thinking browser and use the year.

var year = eval(today.getYear());
if(year < 1900 )
 {alert('Good to go: All browsers and IE 9 & >');}
else
 {alert('Get with it and upgrade your IE to 9 or >');}

First install newtonsoft.json package to Visual Studio using NuGet Package Manager then add the following code:

ClassName ObjectName = JsonConvert.DeserializeObject < ClassName > (jsonObject);

It's an old question, but if someone gets here like me...

This might be result of a wrong date in the server. If you are working with an embedded system this might be the cause... So check your date:

$ date

Even you don't need to measure the length of string. A ! operator can solve everything for you. Remember always: !(empty string) = true !(some string) = false

So you could write:

<input ng-model="somefield">
<span ng-show="!somefield">Sorry, the field is empty!</span>
<span ng-hide="!somefield">Thanks. Successfully validated!</span>

UPDATE 2017

Better documentation is now available and you can use both JSON and JavaScript based configurations: angular-cli documentation proxy

sample https proxy configuration

{
  "/angular": {
     "target":  {
       "host": "github.com",
       "protocol": "https:",
       "port": 443
     },
     "secure": false,
     "changeOrigin": true,
     "logLevel": "info"
  }
}

To my knowledge with Angular 2.0 release setting up proxies using .ember-cli file is not recommended. official way is like below

1. edit "start" of your package.json to look below

   "start": "ng serve --proxy-config proxy.conf.json",

2. create a new file called proxy.conf.json in the root of the project and inside of that define your proxies like below

   {
     "/api": {
       "target": "http://api.yourdomai.com",
       "secure": false
     }
   }
   

3. Important thing is that you use npm start instead of ng serve

For example, To store data in the session, you will typically use the putmethod or the session helper:

// Via a request instance...
$request->session()->put('key', 'value');

or

// Via the global helper...
session(['key' => 'value']);

for retrieving an item from the session, you can use get :

$value = $request->session()->get('key', 'default value');

or global session helper :

$value = session('key', 'default value');

To determine if an item is present in the session, you may use the has method:

if ($request->session()->has('users')) {
//
}

Don't add styles to value of input so use like

function checkFilled() {
    var inputElem = document.getElementById("subEmail");
    if (inputElem.value == "") {
        inputElem.style.backgroundColor = "yellow";
                }
        }

ls -R -L

-L dereferences symbolic links. This will also make it impossible to see any symlinks to files, though - they'll look like the pointed-to file.

Just an addition to the original answer. While this will work:

MethodInfo method = typeof(Sample).GetMethod("GenericMethod");
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);

It is also a little dangerous in that you lose compile-time check for GenericMethod. If you later do a refactoring and rename GenericMethod, this code won't notice and will fail at run time. Also, if there is any post-processing of the assembly (for example obfuscating or removing unused methods/classes) this code might break too.

So, if you know the method you are linking to at compile time, and this isn't called millions of times so overhead doesn't matter, I would change this code to be:

Action<> GenMethod = GenericMethod<int>;  //change int by any base type 
                                          //accepted by GenericMethod
MethodInfo method = this.GetType().GetMethod(GenMethod.Method.Name);
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);

While not very pretty, you have a compile time reference to GenericMethod here, and if you refactor, delete or do anything with GenericMethod, this code will keep working, or at least break at compile time (if for example you remove GenericMethod).

Other way to do the same would be to create a new wrapper class, and create it through Activator. I don't know if there is a better way.

If you are tired of typing your password, create a (chmod 600) file ~/.my.cnf, and put in it:

[client]
user = "you"
password = "your-password"

For the sake of conversation:

echo 'DROP DATABASE foo;' | mysql

Extending @RobBednark's solution to a specific Windows + PuTTY scenario, you can do so:

1. Generate SSH key pair with PuTTYgen (following Manually generating your SSH key in Windows), saving it to a PPK file;

2. With the context menu in Windows Explorer, choose Edit with PuTTYgen. It will prompt for a password.

If you type the wrong password, it will just prompt again.

Note, if you like to type, use the following command on a folder that contains the PPK file: puttygen private-key.ppk -y.

Include the phrase:

@echo off

Right at the top of your bat script.

I was working with this a few days ago, and noticed that sometimes you will need to use the get() function to print the results of your variable. ie :

varnames = c('jan', 'feb', 'march')
file_names = list_files('path to multiple csv files saved on drive')
assign(varnames[1], read.csv(file_names[1]) # This will assign the variable

From there, if you try to print the variable varnames[1], it returns 'jan'. To work around this, you need to do print(get(varnames[1]))

using python format string syntax

>>> mybyte = bytes.fromhex("0F") # create my byte using a hex string
>>> binary_string = "{:08b}".format(int(mybyte.hex(),16))
>>> print(binary_string)
00001111

The second line is where the magic happens. All byte objects have a .hex() function, which returns a hex string. Using this hex string, we convert it to an integer, telling the int() function that it's a base 16 string (because hex is base 16). Then we apply formatting to that integer so it displays as a binary string. The {:08b} is where the real magic happens. It is using the Format Specification Mini-Language format_spec. Specifically it's using the width and the type parts of the format_spec syntax. The 8 sets width to 8, which is how we get the nice 0000 padding, and the b sets the type to binary.

I prefer this method over the bin() method because using a format string gives a lot more flexibility.

Python 3.10 (use |): Example for a function which takes a single argument that is either an int or str and returns either an int or str:

def func(arg: int | str) -> int | str:
              ^^^^^^^^^     ^^^^^^^^^ 
             type of arg   return type

Python 3.5 - 3.9 (use typing.Union):

from typing import Union
def func(arg: Union[int, str]) -> Union[int, str]:
              ^^^^^^^^^^^^^^^     ^^^^^^^^^^^^^^^ 
                type of arg         return type

For the special case of X | None you can use Optional[X].

Programmers may have questions about stack frames not in a broad term (that it is a singe entity in the stack that serves just one function call and keeps return address, arguments and local variables) but in a narrow sense – when the term stack frames is mentioned in context of compiler options.

Whether the author of the question has meant it or not, but the concept of a stack frame from the aspect of compiler options is a very important issue, not covered by the other replies here.

For example, Microsoft Visual Studio 2015 C/C++ compiler has the following option related to stack frames:

• /Oy (Frame-Pointer Omission)

GCC have the following:

• -fomit-frame-pointer (Don't keep the frame pointer in a register for functions that don't need one. This avoids the instructions to save, set up and restore frame pointers; it also makes an extra register available in many functions)

Intel C++ Compiler have the following:

• -fomit-frame-pointer (Determines whether EBP is used as a general-purpose register in optimizations)

which has the following alias:

• /Oy

Delphi has the following command-line option:

• -$W+ (Generate Stack Frames)

In that specific sense, from the compiler’s perspective, a stack frame is just the entry and exit code for the routine, that pushes an anchor to the stack – that can also be used for debugging and for exception handling. Debugging tools may scan the stack data and use these anchors for backtracing, while locating call sites in the stack, i.e. to display names of the functions in the order they have been called hierarchically. For Intel architecture, it is push ebp; mov ebp, esp or enter for entry and mov esp, ebp; pop ebp or leave for exit.

That’s why it is very important to understand for a programmer what a stack frame is in when it comes to compiler options – because the compiler can control whether to generate this code or not.

In some cases, the stack frame (entry and exit code for the routine) can be omitted by the compiler, and the variables will directly be accessed via the stack pointer (SP/ESP/RSP) rather than the convenient base pointer (BP/ESP/RSP). Conditions for omission of the stack frame, for example:

• the function is a leaf function (i.e. an end-entity that doesn’t call other functions);
• there are no try/finally or try/except or similar constructs, i.e. no exceptions are used;
• no routines are called with outgoing parameters on the stack;
• the function has no parameters;
• the function has no inline assembly code;
• etc...

Omitting stack frames (entry and exit code for the routine) can make code smaller and faster, but it may also negatively affect the debuggers’ ability to backtrace the data in the stack and to display it to the programmer. These are the compiler options that determine under which conditions a function should have the entry and exit code, for example: (a) always, (b) never, (c) when needed (specifying the conditions).

Well, you just fire the desired click event:

$(".first").click(function(){
    $(".second").click(); 
    return false;
});

I found two plugins for that. One loads the values from a file and the other lets you configure the values in the job configuration screen.

Envfile Plugin — This plugin enables you to set environment variables via a file. The file's format must be the standard Java property file format.

EnvInject Plugin — This plugin makes it possible to add environment variables and execute a setup script in order to set up an environment for the Job.

No. Java literal null is not an instance of any class. Therefore it can not be an instanceof any class. instanceof will return either false or true therefore the <referenceVariable> instanceof <SomeClass> returns false when referenceVariable value is null.

If you want run formula on worksheet by function that execute SQL statement then use Add-in A-Tools

Example, function BS_SQL("SELECT ..."):

Here is my Maven setup. You can use it as an example. You don't need anything else in order to use Maven.

M2_HOME is used for both Maven 2 and 3

export M2_HOME=/Users/xxx/sdk/apache-maven-3.0.5
export M2=$M2_HOME/bin
export MAVEN_OPTS="-Xmx1048m -Xms256m -XX:MaxPermSize=312M"
export PATH=$M2:$PATH

This might be helpful. You have to just trigger an event.

$("#DropDownID").trigger("liszt:updated");

Where "DropDownID" is ID of <select>.

Junk, or working code

You can replace comm by a variable of your choice that is perhaps shorter, easy to touch-type, and you know does not (and will not) occur in your programs. Examples: xxx, oo, null, nil.

Add this to the stylesheet:

table {
  border-collapse: collapse;
}

JSFiddle.

The reason why it behaves this way is actually described pretty well in the specification:

There are two distinct models for setting borders on table cells in CSS. One is most suitable for so-called separated borders around individual cells, the other is suitable for borders that are continuous from one end of the table to the other.

... and later, for collapse setting:

In the collapsing border model, it is possible to specify borders that surround all or part of a cell, row, row group, column, and column group.

I faced a similar issue while copying a sheet to another workbook. I prefer to avoid using 'activesheet' though as it has caused me issues in the past. Hence I wrote a function to perform this inline with my needs. I add it here for those who arrive via google as I did:

The main issue here is that copying a visible sheet to the last index position results in Excel repositioning the sheet to the end of the visible sheets. Hence copying the sheet to the position after the last visible sheet sorts this issue. Even if you are copying hidden sheets.

Function Copy_WS_to_NewWB(WB As Workbook, WS As Worksheet) As Worksheet
    'Creates a copy of the specified worksheet in the specified workbook
    '   Accomodates the fact that there may be hidden sheets in the workbook
    
    Dim WSInd As Integer: WSInd = 1
    Dim CWS As Worksheet
    
    'Determine the index of the last visible worksheet
    For Each CWS In WB.Worksheets
        If CWS.Visible Then If CWS.Index > WSInd Then WSInd = CWS.Index
    Next CWS
    
    WS.Copy after:=WB.Worksheets(WSInd)
    Set Copy_WS_to_NewWB = WB.Worksheets(WSInd + 1)

End Function

To use this function for the original question (ie in the same workbook) could be done with something like...

Set test = Copy_WS_to_NewWB(Workbooks(1), Workbooks(1).Worksheets(1))
test.name = "test sheet name"

EDIT 04/11/2020 from –user3598756 Adding a slight refactoring of the above code

Function CopySheetToWorkBook(targetWb As Workbook, shToBeCopied As Worksheet, copiedSh As Worksheet) As Boolean
    'Creates a copy of the specified worksheet in the specified workbook
    '   Accomodates the fact that there may be hidden sheets in the workbook

    Dim lastVisibleShIndex As Long
    Dim iSh As Long

    On Error GoTo SafeExit
    
    With targetWb
        'Determine the index of the last visible worksheet
        For iSh = .Sheets.Count To 1 Step -1
            If .Sheets(iSh).Visible Then
                lastVisibleShIndex = iSh
                Exit For
            End If
        Next
    
        shToBeCopied.Copy after:=.Sheets(lastVisibleShIndex)
        Set copiedSh = .Sheets(lastVisibleShIndex + 1)
    End With
    
    CopySheetToWorkBook = True
    Exit Function
    
SafeExit:
    
End Function

other than using different (more descriptive?) variable names, the refactoring manily deals with:

1. turning the Function type into a `Boolean while including returned (copied) worksheet within function parameters list this, to let the calling Sub hande possible errors, like

    Dim WB as Workbook: Set WB = ThisWorkbook ' as an example
    Dim sh as Worksheet: Set sh = ActiveSheet ' as an example
    Dim copiedSh as Worksheet
    If CopySheetToWorkBook(WB, sh, copiedSh) Then
        ' go on with your copiedSh sheet
    Else
        Msgbox "Error while trying to copy '" & sh.Name & "'" & vbcrlf & err.Description
    End If
   

2. having the For - Next loop stepping from last sheet index backwards and exiting at first visible sheet occurence, since we're after the "last" visible one

Method 1:

The following code worked for me. Just adding the destroyAllWindows() didn't close the window. Adding another cv2.waitKey(1) at the end did the job.

im = cv2.imread("./input.jpg")
cv2.imshow("image", im)
cv2.waitKey(0)
cv2.destroyAllWindows()
cv2.waitKey(1)

credit : https://stackoverflow.com/a/50091712/8109630

Note for beginners:

• This will open the image in a separate window, instead of displaying inline on the notebook. That is why we have to use the destroyAllWindows() to close it later.
• So if you don't see a separate window pop up, check if it is behind your current window.
• After you view the image press a key to close the popped up window.

Method 2:

If you want to display on the Jupyter notebook.

from matplotlib import pyplot as plt
import cv2

im = cv2.imread("./input.jpg")
color = cv2.cvtColor(im, cv2.COLOR_BGR2RGB)
plt.imshow(color)
plt.title('Image')
plt.show()

Reinstall JDK and set system variable JAVA_HOME on your JDK. (e.g. C:\tools\jdk7)
And add JAVA_HOME variable to your PATH system variable

Type in command line

echo %JAVA_HOME%

and

java -version

To verify whether your installation was done successfully.

This problem generally occurs in Windows when your "Java Runtime Environment" registry entry is missing or mismatched with the installed JDK. The mismatch can be due to multiple JDKs.

Steps to resolve:

1. Open the Run window:

   Press windows+R

2. Open registry window:

   Type regedit and enter.

3. Go to: \HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\

4. If Java Runtime Environment is not present inside JavaSoft, then create a new Key and give the name Java Runtime Environment.

5. For Java Runtime Environment create "CurrentVersion" String Key and give appropriate version as value:

6. Create a new subkey of 1.8.

7. For 1.8 create a String Key with name JavaHome with the value of JRE home:

Note that if you care about speed and do not need to worry about singularities, solve() should be preferred to ginv() because it is much faster, as you can check:

require(MASS)
mat <- matrix(rnorm(1e6),nrow=1e3,ncol=1e3)

t0 <- proc.time()
inv0 <- ginv(mat)
proc.time() - t0 

t1 <- proc.time()
inv1 <- solve(mat)
proc.time() - t1

I had a similar problem and for my AspNetCore 3.1 application the other answers to this question were not working. I found that configuring a named HttpClient in my Startup.cs and using header propagation of the Cookie header worked perfectly. It also avoids all the concerns about proper disposition of your handler and client. Note if propagation of the request cookies is not what you need (sorry Op) you can set your own cookies when configuring the client factory.

• I used this guide from Microsoft - Make HTTP requests using IHttpClientFactory in ASP.NET Core
• Header propagation is covered in this section - Header propagation middleware

Configure Services with IServiceCollection

services.AddHttpClient("MyNamedClient").AddHeaderPropagation();
services.AddHeaderPropagation(options =>
{
    options.Headers.Add("Cookie");
});

Configure with IApplicationBuilder

builder.UseHeaderPropagation();

• Inject the IHttpClientFactory into your controller or middleware.
• Create your client using var client = clientFactory.CreateClient("MyNamedClient");

I would suggest the open-source library CSharpOptParse. It parses the command line and hydrates a user-defined .NET object with the command-line input. I always turn to this library when writing a C# console application.

It's ugly and I wouldn't recommended it as a final solution when pushing code live, but while building rest functions, it's sometimes handy to have a 'catch-all' parameter grabber:

public static function parseParams() {
    $params = array();
    switch($_SERVER['REQUEST_METHOD']) {
        case "PUT":
        case "DELETE":
            parse_str(file_get_contents('php://input'), $params);
            $GLOBALS["_{$_SERVER['REQUEST_METHOD']}"] = $params;
            break;
        case "GET":
            $params = $_GET;
            break;
        case "POST":
            $params = $_POST;
            break;
        default:
            $params = $_REQUEST;
            break;
    }
    return $params;
}

Someone creative could probably even add to it to handle command line parameters or whatever comes from your IDE. Once you decide what a given rest-function is doing, you can pick one appropriate for that given call to make sure you get what you need for the deploy version. This assumes 'REQUEST_METHOD' is set.

maybe this will help you out:

If all you need is mousedown, you may be able to make do with the document.elementFromPoint method, by:

1. removing the top layer on mousedown,
2. passing the x and y coordinates from the event to the document.elementFromPoint method to get the element underneath, and then
3. restoring the top layer.

Sorry because this is an old post and currently there is more options than before.

db.getSiblingDB("admin").aggregate( [
   { $currentOp: { allUsers: true, idleConnections: true, idleSessions: true } }
  ,{$project:{
            "_id":0
           ,client:{$arrayElemAt:[ {$split:["$client",":"]}, 0 ] }
           ,curr_active:{$cond:[{$eq:["$active",true]},1,0]}

  ,{$group:{_id:"$client",curr_active:{$sum:"$curr_active"},curr_inactive:{$sum:"$curr_inactive"},total:{$sum:1}}}
  ,{$sort:{total:-1}}
] )

Output example:

{ "_id" : "xxx.xxx.xxx.78", "curr_active" : 0, "curr_inactive" : 1428, "total" : 1428 }
{ "_id" : "xxx.xxx.xxx.76", "curr_active" : 0, "curr_inactive" : 1428, "total" : 1428 }
{ "_id" : "xxx.xxx.xxx.73", "curr_active" : 0, "curr_inactive" : 1428, "total" : 1428 }
{ "_id" : "xxx.xxx.xxx.77", "curr_active" : 0, "curr_inactive" : 1428, "total" : 1428 }
{ "_id" : "xxx.xxx.xxx.74", "curr_active" : 0, "curr_inactive" : 1428, "total" : 1428 }
{ "_id" : "xxx.xxx.xxx.75", "curr_active" : 0, "curr_inactive" : 1428, "total" : 1428 }
{ "_id" : "xxx.xxx.xxx.58", "curr_active" : 0, "curr_inactive" : 510, "total" : 510 }
{ "_id" : "xxx.xxx.xxx.57", "curr_active" : 0, "curr_inactive" : 459, "total" : 459 }
{ "_id" : "xxx.xxx.xxx.55", "curr_active" : 0, "curr_inactive" : 459, "total" : 459 }
{ "_id" : "xxx.xxx.xxx.56", "curr_active" : 0, "curr_inactive" : 408, "total" : 408 }
{ "_id" : "xxx.xxx.xxx.47", "curr_active" : 1, "curr_inactive" : 11, "total" : 12 }
{ "_id" : "xxx.xxx.xxx.48", "curr_active" : 1, "curr_inactive" : 7, "total" : 8 }

You can use something like:

add_custom_target(clean-cmake-files
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
)

// clean-all.cmake
set(cmake_generated ${CMAKE_BINARY_DIR}/CMakeCache.txt
                    ${CMAKE_BINARY_DIR}/cmake_install.cmake
                    ${CMAKE_BINARY_DIR}/Makefile
                    ${CMAKE_BINARY_DIR}/CMakeFiles
)

foreach(file ${cmake_generated})

  if (EXISTS ${file})
     file(REMOVE_RECURSE ${file})
  endif()

endforeach(file)

I usually create a "make clean-all" command adding a call to "make clean" to the previous example:

add_custom_target(clean-all
   COMMAND ${CMAKE_BUILD_TOOL} clean
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
)

Don't try to add the "clean" target as a dependence:

add_custom_target(clean-all
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
   DEPENDS clean
)

Because "clean" isn't a real target in CMake and this doesn't work.

Moreover, you should not use this "clean-cmake-files" as dependence of anything:

add_custom_target(clean-all
   COMMAND ${CMAKE_BUILD_TOOL} clean
   DEPENDS clean-cmake-files
)

Because, if you do that, all CMake files will be erased before clean-all is complete, and make will throw you an error searching "CMakeFiles/clean-all.dir/build.make". In consequence, you can not use the clean-all command before "anything" in any context:

add_custom_target(clean-all
   COMMAND ${CMAKE_BUILD_TOOL} clean
   COMMAND ${CMAKE_COMMAND} -P clean-all.cmake
)

That doesn't work either.

1. use the command to start containers in detached mode: docker-compose up -d
2. to view the containers use: docker ps
3. to view logs for a container: docker logs <containerid>

For pandas 0.17 and above, use this :

test = df.sort_values('one', ascending=False)

Since 'one' is a series in the pandas data frame, hence pandas will not accept the arguments in the form of a list.

This work for me

<input type="file" onchange="function();this.value=null;return false;">

It's basically like a callback that express.js use after a certain part of the code is executed and done, you can use it to make sure that part of code is done and what you wanna do next thing, but always be mindful you only can do one res.send in your each REST block...

So you can do something like this as a simple next() example:

app.get("/", (req, res, next) => {
  console.log("req:", req, "res:", res);
  res.send(["data": "whatever"]);
  next();
},(req, res) =>
  console.log("it's all done!");
);

It's also very useful when you'd like to have a middleware in your app...

To load the middleware function, call app.use(), specifying the middleware function. For example, the following code loads the myLogger middleware function before the route to the root path (/).

var express = require('express');
var app = express();

var myLogger = function (req, res, next) {
  console.log('LOGGED');
  next();
}

app.use(myLogger);

app.get('/', function (req, res) {
  res.send('Hello World!');
})

app.listen(3000);

If you search for an exact match, you can use both, = and LIKE.

Using "=" is a tiny bit faster in this case (searching for an exact match) - you can check this yourself by having the same query twice in SQL Server Management Studio, once using "=", once using "LIKE", and then using the "Query" / "Include actual execution plan".

Execute the two queries and you should see your results twice, plus the two actual execution plans. In my case, they were split 50% vs. 50%, but the "=" execution plan has a smaller "estimated subtree cost" (displayed when you hover over the left-most "SELECT" box) - but again, it's really not a huge difference.

But when you start searching with wildcards in your LIKE expression, search performance will dimish. Search "LIKE Mill%" can still be quite fast - SQL Server can use an index on that column, if there is one. Searching "LIKE %expression%" is horribly slow, since the only way SQL Server can satisfy this search is by doing a full table scan. So be careful with your LIKE's !

Well this is the MSDN page that deals with IntPtr.

The first line reads:

A platform-specific type that is used to represent a pointer or a handle.

As to what a pointer or handle is the page goes on to state:

The IntPtr type can be used by languages that support pointers, and as a common means of referring to data between languages that do and do not support pointers.

IntPtr objects can also be used to hold handles. For example, instances of IntPtr are used extensively in the System.IO.FileStream class to hold file handles.

A pointer is a reference to an area of memory that holds some data you are interested in.

A handle can be an identifier for an object and is passed between methods/classes when both sides need to access that object.

In Perl you could do this:

{
  ( VeryLongCondition_1 ) or last;
  ( VeryLongCondition_2 ) or last;
  ( VeryLongCondition_3 ) or last;
  ( VeryLongCondition_4 ) or last;
  ( VeryLongCondition_5 ) or last;
  ( VeryLongCondition_6 ) or last;

  # Guarded code goes here
}

If any of the conditions fail it will just continue on, after the block. If you are defining any variables that you want to keep around after the block, you will need to define them before the block.

To parse the search parameters from the URL, you need to annotate the controller method parameters with [FromQuery], for example:

[Route("api/person")]
public class PersonController : Controller
{
    [HttpGet]
    public string GetById([FromQuery]int id)
    {

    }

    [HttpGet]
    public string GetByName([FromQuery]string firstName, [FromQuery]string lastName)
    {

    }

    [HttpGet]
    public string GetByNameAndAddress([FromQuery]string firstName, [FromQuery]string lastName, [FromQuery]string address)
    {

    }
}

One I haven't seen yet

Math.floor(Date.now() / 1000); // current time in seconds

Another one I haven't seen yet is

var _ = require('lodash'); // from here https://lodash.com/docs#now
_.now();

I had the same issue because my file was called email.py. I renamed the file and the issue disappeared.

Because this captures all exceptions. It's unlikely that your program can recover from any of them.

You should handle only exceptions that you know how to recover from. If you don't anticipate a certain kind of exception, don't handle it, crash loudly (write details to the log), then diagnose logs and fix code.

Swallowing exceptions is bad, don't do this.

it doenst work for me but it prints the correct element to the console

this is the code:

function click(x, y)
{
    var ev = new MouseEvent('click', {
        'view': window,
        'bubbles': true,
        'cancelable': true,
        'screenX': x,
        'screenY': y
    });

    var el = document.elementFromPoint(x, y);
    console.log(el); //print element to console
    el.dispatchEvent(ev);
}
click(400, 400);

you can determine the last element with this code :

for i,element in enumerate(list):
    if (i==len(list)-1):
        print("last element is" + element)

you can also use append function

b = [ ]

for x in range(0, 5):
    b.append(["O"] * 5)

def print_b(b):
    for row in b:
        print " ".join(row)

Not the best answer, but it's an option anyway:

Comment the given line in the web.config.

CSV Files with Custom Delimiters

By default, a comma is used as a delimiter in a CSV file. However, some CSV files can use delimiters other than a comma. Few popular ones are | and \t.

import csv
data_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, delimiter='|')
    writer.writerows(data_list)

output:

SN|Name|Contribution
1|Linus Torvalds|Linux Kernel
2|Tim Berners-Lee|World Wide Web
3|Guido van Rossum|Python Programming

Write CSV files with quotes

import csv

row_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC, delimiter=';')
    writer.writerows(row_list) 

output:

"SN";"Name";"Contribution"
1;"Linus Torvalds";"Linux Kernel"
2;"Tim Berners-Lee";"World Wide Web"
3;"Guido van Rossum";"Python Programming"

As you can see, we have passed csv.QUOTE_NONNUMERIC to the quoting parameter. It is a constant defined by the csv module.

csv.QUOTE_NONNUMERIC specifies the writer object that quotes should be added around the non-numeric entries.

There are 3 other predefined constants you can pass to the quoting parameter:

• csv.QUOTE_ALL - Specifies the writer object to write CSV file with quotes around all the entries.
• csv.QUOTE_MINIMAL - Specifies the writer object to only quote those fields which contain special characters (delimiter, quotechar or any characters in lineterminator)
• csv.QUOTE_NONE - Specifies the writer object that none of the entries should be quoted. It is the default value.

import csv

row_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC,
                        delimiter=';', quotechar='*')
    writer.writerows(row_list)

output:

*SN*;*Name*;*Contribution*
1;*Linus Torvalds*;*Linux Kernel*
2;*Tim Berners-Lee*;*World Wide Web*
3;*Guido van Rossum*;*Python Programming*

Here, we can see that quotechar='*' parameter instructs the writer object to use * as quote for all non-numeric values.

Applications that are not satisfied with only 256 different characters have the options of either using wide characters (more than 8 bits) or a variable-length encoding (a multibyte encoding in C++ terminology) such as UTF-8. Wide characters generally require more space than a variable-length encoding, but are faster to process. Multi-language applications that process large amounts of text usually use wide characters when processing the text, but convert it to UTF-8 when storing it to disk.

The only difference between a string and a wstring is the data type of the characters they store. A string stores chars whose size is guaranteed to be at least 8 bits, so you can use strings for processing e.g. ASCII, ISO-8859-15, or UTF-8 text. The standard says nothing about the character set or encoding.

Practically every compiler uses a character set whose first 128 characters correspond with ASCII. This is also the case with compilers that use UTF-8 encoding. The important thing to be aware of when using strings in UTF-8 or some other variable-length encoding, is that the indices and lengths are measured in bytes, not characters.

The data type of a wstring is wchar_t, whose size is not defined in the standard, except that it has to be at least as large as a char, usually 16 bits or 32 bits. wstring can be used for processing text in the implementation defined wide-character encoding. Because the encoding is not defined in the standard, it is not straightforward to convert between strings and wstrings. One cannot assume wstrings to have a fixed-length encoding either.

If you don't need multi-language support, you might be fine with using only regular strings. On the other hand, if you're writing a graphical application, it is often the case that the API supports only wide characters. Then you probably want to use the same wide characters when processing the text. Keep in mind that UTF-16 is a variable-length encoding, meaning that you cannot assume length() to return the number of characters. If the API uses a fixed-length encoding, such as UCS-2, processing becomes easy. Converting between wide characters and UTF-8 is difficult to do in a portable way, but then again, your user interface API probably supports the conversion.

The RSACryptoServiceProvider(CspParameters) constructor creates a keypair which is stored in the keystore on the local machine. If you already have a keypair with the specified name, it uses the existing keypair.

It sounds as if you are not interested in having the key stored on the machine.

So use the RSACryptoServiceProvider(Int32) constructor:

public static void AssignNewKey(){
    RSA rsa = new RSACryptoServiceProvider(2048); // Generate a new 2048 bit RSA key

    string publicPrivateKeyXML = rsa.ToXmlString(true);
    string publicOnlyKeyXML = rsa.ToXmlString(false);
    // do stuff with keys...
}

EDIT:

Alternatively try setting the PersistKeyInCsp to false:

public static void AssignNewKey(){
    const int PROVIDER_RSA_FULL = 1;
    const string CONTAINER_NAME = "KeyContainer";
    CspParameters cspParams;
    cspParams = new CspParameters(PROVIDER_RSA_FULL);
    cspParams.KeyContainerName = CONTAINER_NAME;
    cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
    cspParams.ProviderName = "Microsoft Strong Cryptographic Provider";
    rsa = new RSACryptoServiceProvider(cspParams);

    rsa.PersistKeyInCsp = false;

    string publicPrivateKeyXML = rsa.ToXmlString(true);
    string publicOnlyKeyXML = rsa.ToXmlString(false);
    // do stuff with keys...
}

__stdcall is the calling convention used for the function. This tells the compiler the rules that apply for setting up the stack, pushing arguments and getting a return value.

There are a number of other calling conventions, __cdecl, __thiscall, __fastcall and the wonderfully named __declspec(naked). __stdcall is the standard calling convention for Win32 system calls.

Wikipedia covers the details.

It primarily matters when you are calling a function outside of your code (e.g. an OS API) or the OS is calling you (as is the case here with WinMain). If the compiler doesn't know the correct calling convention then you will likely get very strange crashes as the stack will not be managed correctly.

How about this:

When the page first loads, do this:

var myTable = document.getElementById("myTable");
myTable.oldHTML=myTable.innerHTML;

Then when you want to clear the table:

myTable.innerHTML=myTable.oldHTML;

The result will be your header row(s) if that's all you started with, the performance is dramatically faster than looping.

SWIFT 3.01

let secondViewController = self.storyboard?.instantiateViewController(withIdentifier: "Conversation_VC") as! Conversation_VC
self.navigationController?.pushViewController(secondViewController, animated: true)

If the database is InnoDB then it might be a better idea to use foreign keys and cascade on delete, this would do what you want and also result in no redundant data being stored.

For this example however I don't think you need the first s:

DELETE s 
FROM spawnlist AS s 
INNER JOIN npc AS n ON s.npc_templateid = n.idTemplate 
WHERE n.type = "monster";

It might be a better idea to select the rows before deleting so you are sure your deleting what you wish to:

SELECT * FROM spawnlist
INNER JOIN npc ON spawnlist.npc_templateid = npc.idTemplate
WHERE npc.type = "monster";

You can also check the MySQL delete syntax here: http://dev.mysql.com/doc/refman/5.0/en/delete.html

if you're under apache, just add an .htaccess file to your directory with this content:

Header set Access-Control-Allow-Origin: *

Header set Access-Control-Allow-Headers: content-type

Header set Access-Control-Allow-Methods: *

Like others have mentioned, you probably want to look at reusing an existing graphing solution, but rotating text isn't too difficult. The somewhat confusing bit (to me) is that you rotate the whole context and then draw on it:

ctx.rotate(Math.PI*2/(i*6));

The angle is in radians. The code is taken from this example, which I believe was made for the transformations part of the MDC canvas tutorial.

Please see the answer below for a more complete solution.

It happened in IE 11 for me. And I was calling the jquery .load function. So I did it the old fashion way and put something in the url to disable cacheing.

$("#divToReplaceHtml").load('@Url.Action("Action", "Controller")/' + @Model.ID + "?nocache=" + new Date().getTime());

code bit should read:

var my_json;
$.getJSON(my_url, function(json) {
  my_json = json;
});

Attention: The other answers only work on SQL Servers with English configuration! Use SET DATEFIRST 7 to ensure DATEPART(DW, ...) returns 1 for Sunday and 7 for Saturday.

Here's a version that is independent of the local setting and does not require to use :

CREATE FUNCTION [dbo].[fct_IsDateWeekend] ( @date DATETIME )
RETURNS BIT
AS
BEGIN
    RETURN CASE WHEN DATEPART(DW, @date + @@DATEFIRST - 1) > 5  THEN 1 ELSE 0 END;
END;

If you don't want to use the function, simply use this in your SELECT statement:

CASE WHEN DATEPART(DW, YourDateTime + @@DATEFIRST - 1) > 5  THEN 'Weekend' ELSE 'Weekday' END

Check your keychain for identities that are missing a private key. I had multiple distribution certificates installed for the same team, one of which was missing the private key. Xcode was only checking the first matching identity in the keychain and automatically using this as opposed to the one that did include the private key.

Removing the matching identity that didn't have a private key made Xcode detect the correct identity again.

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

This worked for me. TypeScript Version: 2.8.3

for (const [key, value] of Object.entries(myMap)) { 
    console.log(key, value);
}

There is no need to install Poppler on your OS. This will work:

pip install Wand

from wand.image import Image

f = "somefile.pdf"
with(Image(filename=f, resolution=120)) as source: 
    for i, image in enumerate(source.sequence):
        newfilename = f[:-4] + str(i + 1) + '.jpeg'
        Image(image).save(filename=newfilename)

This happened to me when I was experimenting with Maven.

Right click project -> Maven -> disable maven nature corrected the problem for me.

If you push for example image to some API and want the result address(response) back you could do:

import requests
url = 'https://uguu.se/api.php?d=upload-tool'
data = {"name": filename}
files = {'file': open(full_file_path, 'rb')}
response = requests.post(url, data=data, files=files)
current_url = response.text
print(response.text)

If you put in

SELECT * FROM Users WHERE RegistrationDate >= '1/20/2009' 

it will automatically convert the string '1/20/2009' into the DateTime format for a date of 1/20/2009 00:00:00. So by using >= you should get every user whose registration date is 1/20/2009 or more recent.

Edit: I put this in the comment section but I should probably link it here as well. This is an article detailing some more in depth ways of working with DateTime's in you queries: http://www.databasejournal.com/features/mssql/article.php/2209321/Working-with-SQL-Server-DateTime-Variables-Part-Three---Searching-for-Particular-Date-Values-and-Ranges.htm

If you are in the fragment itself, you need to call this. Your fragment needs to be the fragment that is being called. Enter code:

getFragmentManager().beginTransaction().remove(yourFragment).commitAllowingStateLoss();

or if you are using supportLib, then you need to call:

getSupportFragmentManager().beginTransaction().remove(yourFragment).commitAllowingStateLoss();

First of all thanks @Arvis for an eye opening explanation.

I prefer different solution to the accepted answer here for this problem. I don't like messing with overriding back behavior any more than absolutely necessary and when I've tried adding and removing fragments on my own without default back stack poping when back button is pressed I found my self in fragment hell :) If you .add f2 over f1 when you remove it f1 won't call any of callback methods like onResume, onStart etc. and that can be very unfortunate.

Anyhow this is how I do it:

Currently on display is only fragment f1.

f1 -> f2

Fragment2 f2 = new Fragment2();
this.getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.main_content,f2).addToBackStack(null).commit();

nothing out of the ordinary here. Than in fragment f2 this code takes you to fragment f3.

f2 -> f3

Fragment3 f3 = new Fragment3();
getActivity().getSupportFragmentManager().popBackStack();
getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.main_content, f3).addToBackStack(null).commit();

I'm not sure by reading docs if this should work, this poping transaction method is said to be asynchronous, and maybe a better way would be to call popBackStackImmediate(). But as far I can tell on my devices it's working flawlessly.

The said alternative would be:

final FragmentActivity activity = getActivity();
activity.getSupportFragmentManager().popBackStackImmediate();
activity.getSupportFragmentManager().beginTransaction().replace(R.id.main_content, f3).addToBackStack(null).commit();

Here there will actually be brief going back to f1 beofre moving on to f3, so a slight glitch there.

This is actually all you have to do, no need to override back stack behavior...

It could be PowerShell's default security level, which (IIRC) will only run signed scripts.

Try typing this:

set-executionpolicy remotesigned

That will tell PowerShell to allow local (that is, on a local drive) unsigned scripts to run.

Then try executing your script again.

Use whatever navigation key you want to get inside the parentheses, then you can use either yi( or yi) to copy everything within the matching parens. This also works with square brackets (e.g. yi]) and curly braces. In addition to y, you can also delete or change text (e.g. ci), di]).

I tried this with double and single-quotes and it appears to work there as well. For your data, I do:

write (*, '(a)') 'Computed solution coefficients:'

Move cursor to the C, then type yi'. Move the cursor to a blank line, hit p, and get

Computed solution coefficients:

As CMS noted, this works for visual mode selection as well - just use vi), vi}, vi', etc.

Yes there is a difference.

• The Runtime.exec(String) method takes a single command string that it splits into a command and a sequence of arguments.

• The ProcessBuilder constructor takes a (varargs) array of strings. The first string is the command name and the rest of them are the arguments. (There is an alternative constructor that takes a list of strings, but none that takes a single string consisting of the command and arguments.)

So what you are telling ProcessBuilder to do is to execute a "command" whose name has spaces and other junk in it. Of course, the operating system can't find a command with that name, and the command execution fails.

Try to use this.$router.go(0); to manually reload the current page.

Ion Todirel already mentioned an answer YES using std::reference_wrapper. Since C++11 we have a mechanism to retrieve object from std::vector and remove the reference by using std::remove_reference. Below is given an example compiled using g++ and clang with option
-std=c++11 and executed successfully.

#include <iostream>
#include <vector>
#include<functional>

class MyClass {
public:
    void func() {
        std::cout << "I am func \n";
    }

    MyClass(int y) : x(y) {}

    int getval()
    {
        return x;
    }

private: 
        int x;
};

int main() {
    std::vector<std::reference_wrapper<MyClass>> vec;

    MyClass obj1(2);
    MyClass obj2(3);

    MyClass& obj_ref1 = std::ref(obj1);
    MyClass& obj_ref2 = obj2;

    vec.push_back(obj_ref1);
    vec.push_back(obj_ref2);

    for (auto obj3 : vec)
    {
        std::remove_reference<MyClass&>::type(obj3).func();      
        std::cout << std::remove_reference<MyClass&>::type(obj3).getval() << "\n";

According to TF 1:1 Symbols Map, in TF 2.0 you should use tf.compat.v1.Session() instead of tf.Session()

https://docs.google.com/spreadsheets/d/1FLFJLzg7WNP6JHODX5q8BDgptKafq_slHpnHVbJIteQ/edit#gid=0

To get TF 1.x like behaviour in TF 2.0 one can run

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

but then one cannot benefit of many improvements made in TF 2.0. For more details please refer to the migration guide https://www.tensorflow.org/guide/migrate

There are a couple more ways with which you can approach this problem. Assuming one of your requirement is to run a shell script/function containing a few shell commands and check if the script ran successfully and throw errors in case of failures.

The shell commands in generally rely on exit-codes returned to let the shell know if it was successful or failed due to some unexpected events.

So what you want to do falls upon these two categories

• exit on error
• exit and clean-up on error

Depending on which one you want to do, there are shell options available to use. For the first case, the shell provides an option with set -e and for the second you could do a trap on EXIT

Should I use exit in my script/function?

Using exit generally enhances readability In certain routines, once you know the answer, you want to exit to the calling routine immediately. If the routine is defined in such a way that it doesn’t require any further cleanup once it detects an error, not exiting immediately means that you have to write more code.

So in cases if you need to do clean-up actions on script to make the termination of the script clean, it is preferred to not to use exit.

Should I use set -e for error on exit?

No!

set -e was an attempt to add "automatic error detection" to the shell. Its goal was to cause the shell to abort any time an error occurred, but it comes with a lot of potential pitfalls for example,

• The commands that are part of an if test are immune. In the example, if you expect it to break on the test check on the non-existing directory, it wouldn't, it goes through to the else condition

  set -e
  f() { test -d nosuchdir && echo no dir; }
  f
  echo survived
  

• Commands in a pipeline other than the last one, are immune. In the example below, because the most recently executed (rightmost) command's exit code is considered ( cat) and it was successful. This could be avoided by setting by the set -o pipefail option but its still a caveat.

  set -e
  somecommand that fails | cat -
  echo survived 
  

Recommended for use - trap on exit

The verdict is if you want to be able to handle an error instead of blindly exiting, instead of using set -e, use a trap on the ERR pseudo signal.

The ERR trap is not to run code when the shell itself exits with a non-zero error code, but when any command run by that shell that is not part of a condition (like in if cmd, or cmd ||) exits with a non-zero exit status.

The general practice is we define an trap handler to provide additional debug information on which line and what cause the exit. Remember the exit code of the last command that caused the ERR signal would still be available at this point.

cleanup() {
    exitcode=$?
    printf 'error condition hit\n' 1>&2
    printf 'exit code returned: %s\n' "$exitcode"
    printf 'the command executing at the time of the error was: %s\n' "$BASH_COMMAND"
    printf 'command present on line: %d' "${BASH_LINENO[0]}"
    # Some more clean up code can be added here before exiting
    exit $exitcode
}

and we just use this handler as below on top of the script that is failing

trap cleanup ERR

Putting this together on a simple script that contained false on line 15, the information you would be getting as

error condition hit
exit code returned: 1
the command executing at the time of the error was: false
command present on line: 15

The trap also provides options irrespective of the error to just run the cleanup on shell completion (e.g. your shell script exits), on signal EXIT. You could also trap on multiple signals at the same time. The list of supported signals to trap on can be found on the trap.1p - Linux manual page

Another thing to notice would be to understand that none of the provided methods work if you are dealing with sub-shells are involved in which case, you might need to add your own error handling.

• On a sub-shell with set -e wouldn't work. The false is restricted to the sub-shell and never gets propagated to the parent shell. To do the error handling here, add your own logic to do (false) || false

  set -e
  (false)
  echo survived
  

• The same happens with trap also. The logic below wouldn't work for the reasons mentioned above.

  trap 'echo error' ERR
  (false)
  

To replace the first occurrence of a pattern with a given string, use ${parameter/pattern/string}:

#!/bin/bash
firstString="I love Suzi and Marry"
secondString="Sara"
echo "${firstString/Suzi/$secondString}"    
# prints 'I love Sara and Marry'

To replace all occurrences, use ${parameter//pattern/string}:

message='The secret code is 12345'
echo "${message//[0-9]/X}"           
# prints 'The secret code is XXXXX'

(This is documented in the Bash Reference Manual, §3.5.3 "Shell Parameter Expansion".)

Note that this feature is not specified by POSIX — it's a Bash extension — so not all Unix shells implement it. For the relevant POSIX documentation, see The Open Group Technical Standard Base Specifications, Issue 7, the Shell & Utilities volume, §2.6.2 "Parameter Expansion".

List iterators guarantee first and foremost that you get the list's elements in the internal order of the list (aka. insertion order). More specifically it is in the order you've inserted the elements or on how you've manipulated the list. Sorting can be seen as a manipulation of the data structure, and there are several ways to sort the list.

I'll order the ways in the order of usefulness as I personally see it:

1. Consider using Set or Bag collections instead

NOTE: I put this option at the top because this is what you normally want to do anyway.

A sorted set automatically sorts the collection at insertion, meaning that it does the sorting while you add elements into the collection. It also means you don't need to manually sort it.

Furthermore if you are sure that you don't need to worry about (or have) duplicate elements then you can use the TreeSet<T> instead. It implements SortedSet and NavigableSet interfaces and works as you'd probably expect from a list:

TreeSet<String> set = new TreeSet<String>();
set.add("lol");
set.add("cat");
// automatically sorts natural order when adding

for (String s : set) {
    System.out.println(s);
}
// Prints out "cat" and "lol"

If you don't want the natural ordering you can use the constructor parameter that takes a Comparator<T>.

Alternatively, you can use Multisets (also known as Bags), that is a Set that allows duplicate elements, instead and there are third-party implementations of them. Most notably from the Guava libraries there is a TreeMultiset, that works a lot like the TreeSet.

2. Sort your list with Collections.sort()

As mentioned above, sorting of Lists is a manipulation of the data structure. So for situations where you need "one source of truth" that will be sorted in a variety of ways then sorting it manually is the way to go.

You can sort your list with the java.util.Collections.sort() method. Here is a code sample on how:

List<String> strings = new ArrayList<String>()
strings.add("lol");
strings.add("cat");

Collections.sort(strings);
for (String s : strings) {
    System.out.println(s);
}
// Prints out "cat" and "lol"

Using comparators

One clear benefit is that you may use Comparator in the sort method. Java also provides some implementations for the Comparator such as the Collator which is useful for locale sensitive sorting strings. Here is one example:

Collator usCollator = Collator.getInstance(Locale.US);
usCollator.setStrength(Collator.PRIMARY); // ignores casing

Collections.sort(strings, usCollator);

Sorting in concurrent environments

Do note though that using the sort method is not friendly in concurrent environments, since the collection instance will be manipulated, and you should consider using immutable collections instead. This is something Guava provides in the Ordering class and is a simple one-liner:

List<string> sorted = Ordering.natural().sortedCopy(strings);

3. Wrap your list with java.util.PriorityQueue

Though there is no sorted list in Java there is however a sorted queue which would probably work just as well for you. It is the java.util.PriorityQueue class.

Nico Haase linked in the comments to a related question that also answers this.

In a sorted collection you most likely don't want to manipulate the internal data structure which is why PriorityQueue doesn't implement the List interface (because that would give you direct access to its elements).

Caveat on the PriorityQueue iterator

The PriorityQueue class implements the Iterable<E> and Collection<E> interfaces so it can be iterated as usual. However, the iterator is not guaranteed to return elements in the sorted order. Instead (as Alderath points out in the comments) you need to poll() the queue until empty.

Note that you can convert a list to a priority queue via the constructor that takes any collection:

List<String> strings = new ArrayList<String>()
strings.add("lol");
strings.add("cat");

PriorityQueue<String> sortedStrings = new PriorityQueue(strings);
while(!sortedStrings.isEmpty()) {
    System.out.println(sortedStrings.poll());
}
// Prints out "cat" and "lol"

4. Write your own SortedList class

NOTE: You shouldn't have to do this.

You can write your own List class that sorts each time you add a new element. This can get rather computation heavy depending on your implementation and is pointless, unless you want to do it as an exercise, because of two main reasons:

1. It breaks the contract that List<E> interface has because the add methods should ensure that the element will reside in the index that the user specifies.
2. Why reinvent the wheel? You should be using the TreeSet or Multisets instead as pointed out in the first point above.

However, if you want to do it as an exercise here is a code sample to get you started, it uses the AbstractList abstract class:

public class SortedList<E> extends AbstractList<E> {

    private ArrayList<E> internalList = new ArrayList<E>();

    // Note that add(E e) in AbstractList is calling this one
    @Override 
    public void add(int position, E e) {
        internalList.add(e);
        Collections.sort(internalList, null);
    }

    @Override
    public E get(int i) {
        return internalList.get(i);
    }

    @Override
    public int size() {
        return internalList.size();
    }

}

Note that if you haven't overridden the methods you need, then the default implementations from AbstractList will throw UnsupportedOperationExceptions.

You can also use jQuery - is(selector) Method:

var lastOpenSite = $(this).siblings().is(':not(.closedTab)');

I used AutoIt to do it.

using AutoIt;
AutoItX.MouseClick("LEFT",150,150,1,0);//1: click once, 0: Move instantaneous

1. Pro:
   • simple
   • regardless of mouse movement
2. Con:
   • since coordinate is screen-based, there should be some caution if the app scales.
   • the drive won't know when the app finish with clicking consequence actions. There should be a waiting period.

Notice that in most suggestions the initial random value that you have got from rand() function, which is typically from 0 to RAND_MAX, is simply wasted. You are creating only one random number out of it, while there is a sound procedure that can give you more.

Assume that you want [min,max] region of integer random numbers. We start from [0, max-min]

Take base b=max-min+1

Start from representing a number you got from rand() in base b.

That way you have got floor(log(b,RAND_MAX)) because each digit in base b, except possibly the last one, represents a random number in the range [0, max-min].

Of course the final shift to [min,max] is simple for each random number r+min.

int n = NUM_DIGIT-1;
while(n >= 0)
{
    r[n] = res % b;
    res -= r[n];
    res /= b;
    n--;
}

If NUM_DIGIT is the number of digit in base b that you can extract and that is

NUM_DIGIT = floor(log(b,RAND_MAX))

then the above is as a simple implementation of extracting NUM_DIGIT random numbers from 0 to b-1 out of one RAND_MAX random number providing b < RAND_MAX.

And an alternative without using any arithmetic and numbers (although there is nothing wrong with that):

React Native hasn't provided the gradient color yet. But still, you can do it with a nmp package called react-native-linear-gradient or you can click here for more info

1. npm install react-native-linear-gradient --save
2. use import LinearGradient from 'react-native-linear-gradient'; in your application file

3.         <LinearGradient colors={['#4c669f', '#3b5998', '#192f6a']}>
             <Text>
               Your Text Here
             </Text>
           </LinearGradient> 

1) First you need to generate EDMX model using your database. To do that you should add new item to your project:

• Select ADO.NET Entity Data Model from the Templates list.
• On the Choose Model Contents page, select the Generate from Database option and click Next.
• Choose your database.
• On the Choose Your Database Objects page, check the Tables. Choose Views or Stored Procedures if you need.

So now you have Model1.edmx file in your project.

2) To generate classes using your model:

• Open your EDMX model designer.
• On the design surface Right Click –> Add Code Generation Item…
• Select Online templates.
• Select EF 4.x DbContext Generator for C#.
• Click ‘Add’.

Notice that two items are added to your project:

• Model1.tt (This template generates very simple POCO classes for each entity in your model)
• Model1.Context.tt (This template generates a derived DbContext to use for querying and persisting data)

3) Read/Write Data example:

 var dbContext = new YourModelClass(); //class derived from DbContext
 var contacts = from c in dbContext.Contacts select c; //read data
 contacts.FirstOrDefault().FirstName = "Alex"; //edit data
 dbContext.SaveChanges(); //save data to DB

Don't forget that you need 4.x version of EntityFramework. You can download EF 4.1 here: Entity Framework 4.1.

There are several factors which means there is no binary answer. The question of what is best for performance depends on your environment. By the way, if your single select with an identifier is not sub-second, something may be wrong with your configuration.

The real question to ask is how do you want to access the data. Single selects support late-binding. For example if you only want employee information, you can select from the Employees table. The foreign key relationships can be used to retrieve related resources at a later time and as needed. The selects will already have a key to point to so they should be extremely fast, and you only have to retrieve what you need. Network latency must always be taken into account.

Joins will retrieve all of the data at once. If you are generating a report or populating a grid, this may be exactly what you want. Compiled and optomized joins are simply going to be faster than single selects in this scenario. Remember, Ad-hoc joins may not be as fast--you should compile them (into a stored proc). The speed answer depends on the execution plan, which details exactly what steps the DBMS takes to retrieve the data.

There isn't really a way to do this without the css getting a little convoluted, but here's the cleanest solution I could put together (the breakpoints in this are just for example purposes, change them to whatever breakpoints you're actually using.) The key is :nth-of-type (or :nth-child -- either would work in this case.)

Smallest viewport:

@media (max-width:$smallest-breakpoint) {

  .row div {
     background: #eee;
   }

  .row div:nth-of-type(2n) {
     background: #fff;
   }

}

Medium viewport:

@media (min-width:$smallest-breakpoint) and (max-width:$mid-breakpoint) {

  .row div {
    background: #eee;
  }

  .row div:nth-of-type(4n+1), .row div:nth-of-type(4n+2) {
    background: #fff;
  }

}

Largest viewport:

@media (min-width:$mid-breakpoint) and (max-width:9999px) {

  .row div {
    background: #eee;
  }

  .row div:nth-of-type(6n+4), 
  .row div:nth-of-type(6n+5), 
  .row div:nth-of-type(6n+6) {
      background: #fff;
  }
}

Working fiddle here

I almost always just use overflow:hidden on my text-elements in those situations, it often works like a charm ;)

.post-container {
 margin: 20px 20px 0 0;
 border:5px solid #333;
}
.post-thumb img {
 float: left;
}
.post-content {
 overflow:hidden;
}

iframe now supports srcdoc which can be used to specify the HTML content of the page to show in the inline frame.

In my case it was because the file was minified with wrong scope. Use Array!

app.controller('StoreController', ['$http', function($http) {
    ...
}]);

Coffee syntax:

app.controller 'StoreController', Array '$http', ($http) ->
  ...

To update one column here are some syntax options:

Option 1

var ls=new int[]{2,3,4};
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>a.status=true);
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
     db.SomeTable
       .Where(x=>ls.Contains(x.friendid))
       .ToList()
       .ForEach(a=>a.status=true);

     db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
    }
    db.SubmitChanges();
}

Update

As requested in the comment it might make sense to show how to update multiple columns. So let's say for the purpose of this exercise that we want not just to update the status at ones. We want to update name and status where the friendid is matching. Here are some syntax options for that:

Option 1

var ls=new int[]{2,3,4};
var name="Foo";
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
    db.SomeTable
        .Where(x=>ls.Contains(x.friendid))
        .ToList()
        .ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
        some.name=name;
    }
    db.SubmitChanges();
}

Update 2

In the answer I was using LINQ to SQL and in that case to commit to the database the usage is:

db.SubmitChanges();

But for Entity Framework to commit the changes it is:

db.SaveChanges()

BehaviourSubject

BehaviourSubject will return the initial value or the current value on Subscription

var bSubject= new Rx.BehaviorSubject(0);  // 0 is the initial value

bSubject.subscribe({
  next: (v) => console.log('observerA: ' + v)  // output initial value, then new values on `next` triggers
});

bSubject.next(1);  // output new value 1 for 'observer A'
bSubject.next(2);  // output new value 2 for 'observer A', current value 2 for 'Observer B' on subscription

bSubject.subscribe({
  next: (v) => console.log('observerB: ' + v)  // output current value 2, then new values on `next` triggers
});

bSubject.next(3);

With output:

observerA: 0
observerA: 1
observerA: 2
observerB: 2
observerA: 3
observerB: 3

Subject

Subject does not return the current value on Subscription. It triggers only on .next(value) call and return/output the value

var subject = new Rx.Subject();

subject.next(1); //Subjects will not output this value

subject.subscribe({
  next: (v) => console.log('observerA: ' + v)
});
subject.subscribe({
  next: (v) => console.log('observerB: ' + v)
});

subject.next(2);
subject.next(3);

With the following output on the console:

observerA: 2
observerB: 2
observerA: 3
observerB: 3

import { Subject } from 'rxjs/Subject';
import { Observable } from 'rxjs/Observable';

export class LanguageComponent implemnts OnInit {
  displayedColumns = ['name', 'native', 'code', 'leavel'];
  user: any;
  private update = new Subject<void>();
  update$ = this.update.asObservable();

  constructor(private authService: AuthService, private dialog: MatDialog) {}

   ngOnInit() {
     this.update$.subscribe(() => { this.refresh()});
   }

   setUpdate() {
     this.update.next();
   }

   add() {
     this.dialog.open(LanguageAddComponent, {
     data: { user: this.user },
   }).afterClosed().subscribe(result => {
     this.setUpdate();
   });
 }

 refresh() {
   this.authService.getAuthenticatedUser().subscribe((res) => {
     this.user = res;
     this.teachDS = new LanguageDataSource(this.user.profile.languages.teach);   
    });
  }
}

We were trying to avoid using the IE specific

$window[0].document.body.clientHeight 

And found that the following jQuery will not consistently yield the same value but eventually does at some point in our page load scenario which worked for us and maintained cross-browser support:

$(document).height()

I'm a bit of a beginner and struggled getting this to work today.

Below is the class that I ended up with. It works but I was wondering how imperfect my solution is. Anyway, I was hoping some of you more experienced folk might be willing to have a look at my IO class and give me some tips. Cheers!

public class HighScore {
    File data = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator);
    File file = new File(data, "highscore.txt");
    private int highScore = 0;

    public int readHighScore() {
        try {
            BufferedReader br = new BufferedReader(new FileReader(file));
            try {
                highScore = Integer.parseInt(br.readLine());
                br.close();
            } catch (NumberFormatException | IOException e) {
                e.printStackTrace();
            }
        } catch (FileNotFoundException e) {
            try {
                file.createNewFile();
            } catch (IOException ioe) {
                ioe.printStackTrace();
            }
            e.printStackTrace();
        }
        return highScore;
    }

    public void writeHighScore(int highestScore) {
        try {
            BufferedWriter bw = new BufferedWriter(new FileWriter(file));
            bw.write(String.valueOf(highestScore));
            bw.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Although the answer that Gunter posted was correct, it is not different than what I already had posted. The problem was not the ENV directive, but the subsequent instruction RUN export $PATH

There's no need to export the environment variables, once you have declared them via ENV in your Dockerfile.

As soon as the RUN export ... lines were removed, my image was built successfully

Based on @Martin Wantke answer, but with some recommended improvements/adjusts...

NOTE: I found this approach very didactic, so I submitted this answer.

Use the modern version of the Fisher–Yates shuffle algorithm:

/**
 * Shuffles array in place.
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    var j, x, i;
    for (i = a.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i + 1));
        x = a[i];
        a[i] = a[j];
        a[j] = x;
    }
    return a;
}

ES2015 (ES6) version

/**
 * Shuffles array in place. ES6 version
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    for (let i = a.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [a[i], a[j]] = [a[j], a[i]];
    }
    return a;
}

Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.

Use

var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);

Implementing prototype

Using Object.defineProperty (method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr). The following will allow you to call arr.shuffle() to shuffle the array arr:

Object.defineProperty(Array.prototype, 'shuffle', {
    value: function() {
        for (let i = this.length - 1; i > 0; i--) {
            const j = Math.floor(Math.random() * (i + 1));
            [this[i], this[j]] = [this[j], this[i]];
        }
        return this;
    }
});

Sparx's Enterprise Architect performs round-tripping of Python source. They have a free time-limited trial edition.

I would say not.

If the column does accept null values, then there's nothing to stop you inserting a null value into the field. As far as I'm aware, the default value only applies on creation of a new row.

With not null set, then you can't insert a null value into the field as it'll throw an error.

Think of it as a fail safe mechanism to prevent nulls.

If you want a list of lists:

[[1, 3, 8], [2, 4, 9]]

If a list of tuples is OK:

[(1, 3, 8), (2, 4, 9)]

I've got a similar error when installing FCL that needs CCD lib(libccd) like this:

/usr/bin/ld: /usr/local/lib/libccd.a(ccd.o): relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; recompile with -fPIC

I find that there is two different files named "libccd.a" :

1. /usr/local/lib/libccd.a
2. /usr/local/lib/x86_64-linux-gnu/libccd.a

I solved the problem by removing the first file.

This is how to simply get the path of pg_config

$ which pg_config                 // prints the directory location 
/usr/bin/pg_config

assert is a debugging tool that will cause the program to throw an AssertionFailed exception if the condition is not true. In this case, the program will throw an exception if either of the two conditions following it evaluate to false. Generally speaking, assert should not be used in production code

You can use Math.pow instead:

https://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Math.html#pow%28double,%20double%29

The following works:

from bs4 import BeautifulSoup

soup = BeautifulSoup('<META NAME="City" content="Austin">', 'html.parser')

metas = soup.find_all("meta")

for meta in metas:
    print meta.attrs['content'], meta.attrs['name']

I would also note there are two ways to get the number of ms in the time point. I'm not sure which one is better, I've benchmarked them and they both have the same performance, so I guess it's a matter of preference. Perhaps Howard could chime in:

auto now = system_clock::now();

//Cast the time point to ms, then get its duration, then get the duration's count.
auto ms = time_point_cast<milliseconds>(now).time_since_epoch().count();

//Get the time point's duration, then cast to ms, then get its count.
auto ms = duration_cast<milliseconds>(tpBid.time_since_epoch()).count();

The first one reads more clearly in my mind going from left to right.

Looking at the error message, part of the code of your Default.aspx is :

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="AmeriaTestTask.Default" %>

but AmeriaTestTask.Default does not exists, so you have to change it, most probably to the class defined in Default.aspx.cs. For example for web api aplications, the class defined in Global.asax.cs is : public class WebApiApplication : System.Web.HttpApplication and in the asax page you have :

<%@ Application Codebehind="Global.asax.cs" Inherits="MyProject.WebApiApplication" Language="C#" %>

or, open a cmd window, then call the batch from there, the output will be on the screen.

You can use the option -C (or --directory if you prefer long options) to give the target directory of your choice in case you are using the Gnu version of tar. The directory should exist:

mkdir foo
tar -xzf bar.tar.gz -C foo

If you are not using a tar capable of extracting to a specific directory, you can simply cd into your target directory prior to calling tar; then you will have to give a complete path to your archive, of course. You can do this in a scoping subshell to avoid influencing the surrounding script:

mkdir foo
(cd foo; tar -xzf ../bar.tar.gz)  # instead of ../ you can use an absolute path as well

Or, if neither an absolute path nor a relative path to the archive file is suitable, you also can use this to name the archive outside of the scoping subshell:

TARGET_PATH=a/very/complex/path/which/might/even/be/absolute
mkdir -p "$TARGET_PATH"
(cd "$TARGET_PATH"; tar -xzf -) < bar.tar.gz

Splice is good, everyone explain splice so I didn't explain it. You can also use delete keyword in JavaScript, it's good. You can use $.grep also to manipulate this using jQuery.

The jQuery Way :

data.items = jQuery.grep(
                data.items, 
                function (item,index) { 
                  return item.id !=  "1"; 
                });

DELETE Way:

delete data.items[0]

For Adding PUSH is better the splice, because splice is heavy weighted function. Splice create a new array , if you have a huge size of array then it may be troublesome. delete is sometime useful, after delete if you look for the length of the array then there is no change in length there. So use it wisely.

May this code help you. It works in my case.

$filename = "D:\xampp\htdocs\wordpress/wp-content/uploads/json/2018-10-25.json";
    $fileUrl = "http://localhost/wordpress/wp-content/uploads/json/2018-10-25.json";
    if(!file_exists($filename)):
        $handle = fopen( $filename, 'a' ) or die( 'Cannot open file:  ' . $fileUrl ); //implicitly creates file
        fwrite( $handle, json_encode(array()));
        fclose( $handle );
    endif;
    $response = file_get_contents($filename);
    $tempArray = json_decode($response);
    if(!empty($tempArray)):
        $count = count($tempArray) + 1;
    else:
        $count = 1;
    endif;
    $tempArray[] = array_merge(array("sn." => $count), $data);
    $jsonData = json_encode($tempArray);
    file_put_contents($filename, $jsonData);

First check that the extension is properly loaded in phpinfo(); (something like sqlsrv should appear). If not, the extension isn't properly loaded. You also need to restart apache after installing an extension.

I was able to accomplish this using a FormArray of FormGroups. The FormGroup consists of two controls. One for the data and one to store the checked boolean.

TS

options: options[] = [{id: 1, text: option1}, {id: 2, text: option2}];

this.fb.group({
  options: this.fb.array([])
})    

populateFormArray() {    
  this.options.forEach(option => {                       
    let checked = ***is checked logic here***;            
    this.checkboxGroup.get('options').push(this.createOptionGroup(option, checked))
  });       
}  

createOptionGroup(option: Option, checked: boolean) {
  return this.fb.group({      
    option: this.fb.control(option),
    checked: this.fb.control(checked)
  });
}

HTML

This allows you to loop through the options and bind to the corresponding checked control.

<form [formGroup]="checkboxGroup">
  <div formArrayName="options" *ngFor="let option of options; index as i">   
    <div [formGroupName]="i">
      <input type="checkbox" formControlName="checked" />
      {{ option.text }}
    </div>
  </div>       
</form>

Output

The form returns data in the form {option: Option, checked: boolean}[].

You can get a list of checked options using the below code

 this.checkboxGroup.get('options').value.filter(el => el.checked).map(el => el.option);

I would like to note that previous answers made many assumptions about the user's knowledge. This answer attempts to answer the question at a more tutorial level.

For every invocation of Python, sys.argv is automatically a list of strings representing the arguments (as separated by spaces) on the command-line. The name comes from the C programming convention in which argv and argc represent the command line arguments.

You'll want to learn more about lists and strings as you're familiarizing yourself with Python, but in the meantime, here are a few things to know.

You can simply create a script that prints the arguments as they're represented. It also prints the number of arguments, using the len function on the list.

from __future__ import print_function
import sys
print(sys.argv, len(sys.argv))

The script requires Python 2.6 or later. If you call this script print_args.py, you can invoke it with different arguments to see what happens.

> python print_args.py
['print_args.py'] 1

> python print_args.py foo and bar
['print_args.py', 'foo', 'and', 'bar'] 4

> python print_args.py "foo and bar"
['print_args.py', 'foo and bar'] 2

> python print_args.py "foo and bar" and baz
['print_args.py', 'foo and bar', 'and', 'baz'] 4

As you can see, the command-line arguments include the script name but not the interpreter name. In this sense, Python treats the script as the executable. If you need to know the name of the executable (python in this case), you can use sys.executable.

You can see from the examples that it is possible to receive arguments that do contain spaces if the user invoked the script with arguments encapsulated in quotes, so what you get is the list of arguments as supplied by the user.

Now in your Python code, you can use this list of strings as input to your program. Since lists are indexed by zero-based integers, you can get the individual items using the list[0] syntax. For example, to get the script name:

script_name = sys.argv[0] # this will always work.

Although interesting, you rarely need to know your script name. To get the first argument after the script for a filename, you could do the following:

filename = sys.argv[1]

This is a very common usage, but note that it will fail with an IndexError if no argument was supplied.

Also, Python lets you reference a slice of a list, so to get another list of just the user-supplied arguments (but without the script name), you can do

user_args = sys.argv[1:] # get everything after the script name

Additionally, Python allows you to assign a sequence of items (including lists) to variable names. So if you expect the user to always supply two arguments, you can assign those arguments (as strings) to two variables:

user_args = sys.argv[1:]
fun, games = user_args # len(user_args) had better be 2

So, to answer your specific question, sys.argv[1] represents the first command-line argument (as a string) supplied to the script in question. It will not prompt for input, but it will fail with an IndexError if no arguments are supplied on the command-line following the script name.

See themes on android: http://developer.android.com/guide/topics/ui/themes.html.

Under themes.xml there should be android:windowAnimationStyle where you can see the declaration of the style in styles.xml.

Example implementation:

<style name="AppTheme" parent="...">

    ...

    <item name="android:windowAnimationStyle">@style/WindowAnimationStyle</item>

</style>

<style name="WindowAnimationStyle">
    <item name="android:windowEnterAnimation">@android:anim/fade_in</item>
    <item name="android:windowExitAnimation">@android:anim/fade_out</item>
</style>

Try this:

http://jsfiddle.net/HRz6X/2/

You need to add left: 0 and right: 0 (not supported by IE6). Or specify a width

You can simply return if you want to skip the current iteration.

Since you're in a function, if you return before doing anything else, then you have effectively skipped execution of the code below the return statement.

You're probably missing some dependencies.

Locate the dependencies you're missing with mvn dependency:tree, then install them manually, and build your project with the -o (offline) option.

Sure, the syntax is exactly the same as C - NewObj* pNew = (NewObj*)oldObj;

In this situation you may wish to consider supplying this list as a parameter to the constructor, something like:

// SelectionListViewController
-(id) initWith:(SomeListClass*)anItemList
{
  self = [super init];

  if ( self ) {
    [self setList: anItemList];
  }

  return self;
}

Then use it like this:

myEditController = [[SelectionListViewController alloc] initWith: listOfItems];

According to http://youmightnotneedjquery.com/#ready a nice replacement that still works with IE8 is

function ready(fn) {_x000D_
  if (document.readyState != 'loading') {_x000D_
    fn();_x000D_
  } else if (document.addEventListener) {_x000D_
    document.addEventListener('DOMContentLoaded', fn);_x000D_
  } else {_x000D_
    document.attachEvent('onreadystatechange', function() {_x000D_
      if (document.readyState != 'loading')_x000D_
        fn();_x000D_
    });_x000D_
  }_x000D_
}_x000D_
_x000D_
// test_x000D_
window.ready(function() {_x000D_
    alert('it works');_x000D_
});

improvements: Personally I would also check if the type of fn is a function. And as @elliottregan suggested remove the event listener after use.

The reason I answer this question late is because I was searching for this answer but could not find it here. And I think this is the best solution.

Statement s = cd.createStatement();
ResultSet r = s.executeQuery("SELECT COUNT(*) AS rowcount FROM FieldMaster");
r.next();
int count = r.getInt("rowcount");
r.close();
System.out.println("MyTable has " + count + " row(s).");

Sometimes JDBC does not support following method gives Error like `TYPE_FORWARD_ONLY' use this solution

Sqlite does not support in JDBC.

resultSet.last();
size = resultSet.getRow();
resultSet.beforeFirst();

So at that time use this solution.

Thanks..

When I'm converting from JSX to TSX and we keep some libraries as js/jsx and convert others to ts/tsx I almost always forget to change the js/jsx import statements in the TSX\TS files from

import * as ComponentName from "ComponentName";

to

import ComponentName from "ComponentName";

If calling an old JSX (React.createClass) style component from TSX, then use

var ComponentName = require("ComponentName")

I had the same error, then I tried <asp:PostBackTrigger ControlID="xyz"/> instead of AsyncPostBackTrigger .This worked for me. It is because we don't want a partial postback.

As of React 0.15, the most concise method is:

<input ref={input => input && input.focus()}/>

List<T> has a Reverse() method, however it only reverses the order of two (or more) consecutive items.

your_list.Reverse(index, 2);

Where the second parameter 2 indicates we are reversing the order of 2 items, starting with the item at the given index.

Branches are made of wood and grow from the trunk of the tree. Tags are made of paper (derivative of wood) and hang like Christmas Ornaments from various places in the tree.

Your project is the tree, and your feature that will be added to the project will grow on a branch. The answer is branch.

When an element already has a class name defined, its influence on the element is tied to its position in the string of class names. Later classes override earlier ones, if there is a conflict.

Adding a class to an element ought to move the class name to the sharp end of the list, if it exists already.

document.addClass= function(el, css){
    var tem, C= el.className.split(/\s+/), A=[];    
    while(C.length){
        tem= C.shift();
        if(tem && tem!= css) A[A.length]= tem;
    }
    A[A.length]= css;
    return el.className= A.join(' ');   
}

Try the following snippet. You can call the the below stored procedure from your application, so that NoOfUses in the coupon table will be updated.

CREATE PROCEDURE [dbo].[sp_UpdateCouponCount]
AS

Declare     @couponCount int,
            @CouponName nvarchar(50),
            @couponIdFromQuery int


Declare curP cursor For

  select COUNT(*) as totalcount , Name as name,couponuse.couponid  as couponid from Coupon as coupon 
  join CouponUse as couponuse on coupon.id = couponuse.couponid
  where couponuse.id=@cuponId
  group by couponuse.couponid , coupon.Name

OPEN curP 
Fetch Next From curP Into @couponCount, @CouponName,@couponIdFromQuery

While @@Fetch_Status = 0 Begin

    print @couponCount
    print @CouponName

    update Coupon SET NoofUses=@couponCount
    where couponuse.id=@couponIdFromQuery


Fetch Next From curP Into @couponCount, @CouponName,@couponIdFromQuery

End -- End of Fetch

Close curP
Deallocate curP

Hope this helps!
