You should capitalize names of your classes. After doing that do this in your school class,

Classroom cls = new Classroom();
cls.setTeacherName(newTeacherName);

Also I'd recommend you use some kind of IDE such as eclipse, which can help you with your code for instance generate getters and setters for you. Ex: right click Source -> Generate getters and setters

You need to use a commercial library if you need perfect html rendering in pdf.

ExpertPdf Html To Pdf Converter is very easy to use and it supports the latest html5/css3. You can either convert an entire url to pdf:

using ExpertPdf.HtmlToPdf; 
byte[] pdfBytes = new PdfConverter().GetPdfBytesFromUrl(url);

or a html string:

using ExpertPdf.HtmlToPdf; 
byte[] pdfBytes = new PdfConverter().GetPdfBytesFromHtmlString(html, baseUrl);

You also have the alternative to directly save the generated pdf document to a Stream of file on the disk.

I had the same problem on my virtual windows 7.

1. Go to Network Connections
2. Alt > Advanced > Advanced Settings...
3. In the second tab bring the internet networks interface on the top

Here are a few ways of removing a single ' from a string in python.

• str.replace

  replace is usually used to return a string with all the instances of the substring replaced.

  "A single ' char".replace("'","")
  

• str.translate

  In Python 2

  To remove characters you can pass the first argument to the funstion with all the substrings to be removed as second.

  "A single ' char".translate(None,"'")
  

  In Python 3

  You will have to use str.maketrans

  "A single ' char".translate(str.maketrans({"'":None}))
  

• re.sub

  Regular Expressions using re are even more powerful (but slow) and can be used to replace characters that match a particular regex rather than a substring.

  re.sub("'","","A single ' char")
  

Other Ways

There are a few other ways that can be used but are not at all recommended. (Just to learn new ways). Here we have the given string as a variable string.

• Using list comprehension

  ''.join([c for c in string if c != "'"])
  

• Using generator Expression

  ''.join(c for c in string if c != "'")
  

Another final method can be used also (Again not recommended - works only if there is only one occurrence )

• Using list call along with remove and join.

  x = list(string)
  x.remove("'")
  ''.join(x)
  

Try using this code:

ALTER TABLE `table name` 
    CHANGE COLUMN `column name` `column name` datatype NOT NULL, 
    ADD PRIMARY KEY (`column name`) ;

You need to store all of the extra rows in the files in your dictionary, not just one of them:

dict1 = {row[0]: row[1:] for row in r}
...
dict2 = {row[0]: row[1:] for row in r}

Then, since the values in the dictionaries are lists, you need to just concatenate the lists together:

w.writerows([[key] + dict1.get(key, []) + dict2.get(key, []) for key in keys])

If you guys still interested, here is my workaround based on Guzzle middleware feature:

1. Create JsonAwaraResponse that will decode JSON response by Content-Type HTTP header, if not - it will act as standard Guzzle Response:

   <?php
   
   namespace GuzzleHttp\Psr7;
   
   
   class JsonAwareResponse extends Response
   {
       /**
        * Cache for performance
        * @var array
        */
       private $json;
   
       public function getBody()
       {
           if ($this->json) {
               return $this->json;
           }
           // get parent Body stream
           $body = parent::getBody();
   
           // if JSON HTTP header detected - then decode
           if (false !== strpos($this->getHeaderLine('Content-Type'), 'application/json')) {
               return $this->json = \json_decode($body, true);
           }
           return $body;
       }
   }
   

2. Create Middleware which going to replace Guzzle PSR-7 responses with above Response implementation:

   <?php
   
   $client = new \GuzzleHttp\Client();
   
   /** @var HandlerStack $handler */
   $handler = $client->getConfig('handler');
   $handler->push(\GuzzleHttp\Middleware::mapResponse(function (\Psr\Http\Message\ResponseInterface $response) {
       return new \GuzzleHttp\Psr7\JsonAwareResponse(
           $response->getStatusCode(),
           $response->getHeaders(),
           $response->getBody(),
           $response->getProtocolVersion(),
           $response->getReasonPhrase()
       );
   }), 'json_decode_middleware');
   

After this to retrieve JSON as PHP native array use Guzzle as always:

$jsonArray = $client->get('http://httpbin.org/headers')->getBody();

Tested with guzzlehttp/guzzle 6.3.3

Also remember that it must be:

#include "stdafx.h"
#include <iostream>

and not the other way around

#include <iostream>
#include "stdafx.h"

first of all;

a Fragment must be inside a FragmentActivity, that's the first rule,

a FragmentActivity is quite similar to a standart Activity that you already know, besides having some Fragment oriented methods

second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView, where you inflate your layout, think of it as the setContentLayout

here is an example:

    @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {     mView       = inflater.inflate(R.layout.fragment_layout, container, false);       return mView; } 

and continu your work based on that mView, so to find a View by id, call mView.findViewById(..);

for the FragmentActivity part:

the xml part "must" have a FrameLayout in order to inflate a fragment in it

        <FrameLayout             android:id="@+id/content_frame"             android:layout_width="match_parent"             android:layout_height="match_parent"  >         </FrameLayout> 

as for the inflation part

getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();

begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site

Without using an overlay, you can use pointer-events: none on the div in CSS, but this does not work in IE or Opera.

div.disabled
{
  pointer-events: none;

  /* for "disabled" effect */
  opacity: 0.5;
  background: #CCC;
}

Reference

An other solution is to use the special variable ansible_limit which is the contents of the --limit CLI option for the current execution of Ansible.

- hosts: "{{ ansible_limit | default(omit) }}"

If the --limit option is omitted, then Ansible issues a warning, but does nothing since no host matched.

[WARNING]: Could not match supplied host pattern, ignoring: None

PLAY ****************************************************************
skipping: no hosts matched

Try this if you are on ubuntu:

sudo apt-get update
sudo apt-get install build-essential libpq-dev libssl-dev openssl libffi-dev zlib1g-dev
sudo apt-get install python3-pip python3.7-dev
sudo apt-get install python3.7

In case you don't have the repository and so it fires a not-found package you first have to install this:

sudo apt-get install -y software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update

more info here: http://devopspy.com/python/install-python-3-6-ubuntu-lts/

If escaping your single quote with another single quote isn't working for you (like it didn't for one of my recent REPLACE() queries), you can use SET QUOTED_IDENTIFIER OFF before your query, then SET QUOTED_IDENTIFIER ON after your query.

For example

SET QUOTED_IDENTIFIER OFF;

UPDATE TABLE SET NAME = REPLACE(NAME, "'S", "S");

SET QUOTED_IDENTIFIER ON;
-- set OFF then ON again

I think these official guide should work for your case.

VS Code allows you to quickly search over all files in the currently-opened folder. Press Ctrl+Shift+F and enter in your search term. Search results are grouped into files containing the search term, with an indication of the hits in each file and its location. Expand a file to see a preview of all of the hits within that file. Then single-click on one of the hits to view it in the editor.

this works for me...

using System.IO;

private long GetTotalFreeSpace(string driveName)
{
    foreach (DriveInfo drive in DriveInfo.GetDrives())
    {
        if (drive.IsReady && drive.Name == driveName)
        {
            return drive.TotalFreeSpace;
        }
    }
    return -1;
}

good luck!

PyCharm. It is best the IDE for Python,Django, and web development I've tried so far. It is totally worth the money.

find "$PWD" -type f -name "*.in"

java.lang.Thread.activeCount()

It will return the number of active threads in the current thread's thread group.

docs: http://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#activeCount()

One more way/syntax to do it is: git log -S "word"
Like this you can search for example git log -S "with whitespaces and stuff @/#ü !"

this prototype:

  int execlp(const char *file, const char *arg, ...);

Says that execlp ìs a variable argument function. It takes 2 const char *. The rest of the arguments, if any, are the additional arguments to hand over to program we want to run - also char * - all these are C strings (and the last argument must be a NULL pointer)

So, the file argument is the path name of an executable file to be executed. arg is the string we want to appear as argv[0] in the executable. By convention, argv[0] is just the file name of the executable, normally it's set to the same as file.

The ... are now the additional arguments to give to the executable.

Say you run this from a commandline/shell:

$ ls

That'd be execlp("ls", "ls", (char *)NULL); Or if you run

$ ls -l /

That'd be execlp("ls", "ls", "-l", "/", (char *)NULL);

So on to execlp("/bin/sh", ..., "ls -l /bin/??", ...);

Here you are going to the shell, /bin/sh , and you're giving the shell a command to execute. That command is "ls -l /bin/??". You can run that manually from a commandline/shell:

 $ ls -l /bin/??

Now, how do you run a shell and tell it to execute a command ? You open up the documentation/man page for your shell and read it.

What you want to run is:

$ /bin/sh -c "ls -l /bin/??"

This becomes

  execlp("/bin/sh","/bin/sh", "-c", "ls -l /bin/??", (char *)NULL);

Side note: The /bin/?? is doing pattern matching, this pattern matching is done by the shell, and it expands to all files under /bin/ with 2 characters. If you simply did

  execlp("ls","ls", "-l", "/bin/??", (char *)NULL);

Probably nothing would happen (unless there's a file actually named /bin/??) as there's no shell that interprets and expands /bin/??

I error occor. When you are trying to access a file which is not in the director. Carefully check path in the view

 $this->load->view('path');

default root path of view function is application/view .

I had the same error. I was trying to access files like this

 $this->load->view('pages/view/file.php');

Actually I have the class Pages and function. I built the function with one argument to call the any files from the director application/view/pages . I was put the wrong path. The above path pages/view/files can be used when you are trying to access the controller. Not for the view. MVC gave a lot confusion. I had this problem. I just solve it. Thanks.

You should learn objective c and program native apps. Do not rely on these things you think will make life easier. Apple has made sure the easiest way is using their native tools and language. For your 100 lines of javascript I can do the same in 3 lines of code or no code at all depending on the element. Watch some tutorials - if you understand javascript then objective c is not hard. Workarounds are miserable and apple can pull the plug on you anytime they want.

I needed to do the same thing and created a method to do it.

// Now you can just call
var ctx = document.getElementById("rounded-rect").getContext("2d");
// Draw using default border radius, 
// stroke it but no fill (function's default values)
roundRect(ctx, 5, 5, 50, 50);
// To change the color on the rectangle, just manipulate the context
ctx.strokeStyle = "rgb(255, 0, 0)";
ctx.fillStyle = "rgba(255, 255, 0, .5)";
roundRect(ctx, 100, 5, 100, 100, 20, true);
// Manipulate it again
ctx.strokeStyle = "#0f0";
ctx.fillStyle = "#ddd";
// Different radii for each corner, others default to 0
roundRect(ctx, 300, 5, 200, 100, {
  tl: 50,
  br: 25
}, true);

ERRORLEVEL will contain the return code of the last command. Sadly you can only check >= for it.

Note specifically this line in the MSDN documentation for the If statement:

errorlevel Number

Specifies a true condition only if the previous program run by Cmd.exe returned an exit code equal to or greater than Number.

So to check for 0 you need to think outside the box:

IF ERRORLEVEL 1 GOTO errorHandling
REM no error here, errolevel == 0
:errorHandling

Or if you want to code error handling first:

IF NOT ERRORLEVEL 1 GOTO no_error
REM errorhandling, errorlevel >= 1
:no_error

savefig specifies the DPI for the saved figure (The default is 100 if it's not specified in your .matplotlibrc, have a look at the dpi kwarg to savefig). It doesn't inheret it from the DPI of the original figure.

The DPI affects the relative size of the text and width of the stroke on lines, etc. If you want things to look identical, then pass fig.dpi to fig.savefig.

E.g.

import matplotlib.pyplot as plt

fig = plt.figure()
plt.plot(range(10))
fig.savefig('temp.png', dpi=fig.dpi)

Use an Iterator and call remove():

Iterator<String> iter = myArrayList.iterator();

while (iter.hasNext()) {
    String str = iter.next();

    if (someCondition)
        iter.remove();
}

Do not bother with encoding. Use a text node instead. Data in text node is guaranteed to be treated as text.

document.body.appendChild(document.createTextNode("Your&funky<text>here"))

You can use font face like this:

@font-face {
  font-family:"Name-Of-Font";
  src: url("yourfont.ttf") format("truetype");
}

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

public static void Main(string[] args)
{
    int[] numbers = new int[10];

    Console.Write("index ");

    for (int i = 0; i < numbers.Length; i++)
    {
        numbers[i] = i;
        Console.Write(numbers[i] + " ");
    }

    Console.WriteLine("");
    Console.WriteLine("");
    Console.Write("value ");

    for (int i = 0; i < numbers.Length; i++)
    {
        numbers[i] = numbers.Length - i;
        Console.Write(numbers[i] + " ");
    }

    Console.ReadKey();
}

In Short

android:id="@+id/my_button"

+id Plus sign tells android to add or create a new id in Resources.

while

android:layout_below="@id/my_button"

it just help to refer the already generated id..

After trying the simple pip install route for eyeD3, pytaglib, and ID3 modules recommended here, I found this fourth option was the only one to work. The rest had import errors with missing dependencies in C++ or something magic or some other library that pip missed. So go with this one for basic reading of ID3 tags (all versions):

https://pypi.python.org/pypi/tinytag/0.18.0

from tinytag import TinyTag
tag = TinyTag.get('/some/music.mp3')

List of possible attributes you can get with TinyTag:

tag.album         # album as string
tag.albumartist   # album artist as string
tag.artist        # artist name as string
tag.audio_offset  # number of bytes before audio data begins
tag.bitrate       # bitrate in kBits/s
tag.disc          # disc number
tag.disc_total    # the total number of discs
tag.duration      # duration of the song in seconds
tag.filesize      # file size in bytes
tag.genre         # genre as string
tag.samplerate    # samples per second
tag.title         # title of the song
tag.track         # track number as string
tag.track_total   # total number of tracks as string
tag.year          # year or data as string

It was tiny and self-contained, as advertised.

Sometimes, you need to list the variables of an object and not for debugging purposes. The right way to do it is using get_object_vars($object). It returns an array that has all the class variables and their value. You can then loop through them in a foreach loop. If used within the object itself, simply do get_object_vars($this)

I feel that MWV (Model View Whatever) or MV* is a more flexible term to describe some of the uniqueness of Angularjs in my opinion. It helped me to understand that it is more than a MVC (Model View Controller) JavaScript framework, but it still uses MVC as it has a Model View, and Controller.

It also can be considered as a MVP (Model View Presenter) pattern. I think of a Presenter as the user-interface business logic in Angularjs for the View. For example by using filters that can format data for display. It's not business logic, but display logic and it reminds me of the MVP pattern I used in GWT.

In addition, it also can be a MVVM (Model View View Model) the View Model part being the two-way binding between the two. Last of all it is MVW as it has other patterns that you can use as well as mentioned by @Steve Chambers.

I agree with the other answers that getting pedantic on these terms can be detrimental, as the point is to understand the concepts from the terms, but by the same token, fully understanding the terms helps one when they are designing their application code, knowing what goes where and why.

You can achieve this using a meta tag as follows:

<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />

Alternative answer to an older question refers to John Skeet's Library that has tools for letting you write primitive data types directly into a byte[] with an Index offset. Far better than BitConverter if you need performance.

Older thread discussing this issue here

John Skeet's Libraries are here

Just download the source and look at the MiscUtil.Conversion namespace. EndianBitConverter.cs handles everything for you.

I know its already answered, but theres a better solution here use this code :

for ( Field f : context.getFields() ) {
     if ( f.getType() == String.class ) || ( f.getType() == String.class ) ) {
           //DO String To JSON
     }
     /// And so on...
}

This way you can access variables from class without manually typing them..

Faster and better .. Hope this helps.

Cheers. :D

Since the question is so popular, it may be useful to add on what to do if you want to control the type property name and its value.

The long way is to write custom JsonConverters to handle (de)serialization by manually checking and setting the type property.

A simpler way is to use JsonSubTypes, which handles all the boilerplate via attributes:

[JsonConverter(typeof(JsonSubtypes), "Sound")]
[JsonSubtypes.KnownSubType(typeof(Dog), "Bark")]
[JsonSubtypes.KnownSubType(typeof(Cat), "Meow")]
public class Animal
{
    public virtual string Sound { get; }
    public string Color { get; set; }
}

public class Dog : Animal
{
    public override string Sound { get; } = "Bark";
    public string Breed { get; set; }
}

public class Cat : Animal
{
    public override string Sound { get; } = "Meow";
    public bool Declawed { get; set; }
}

It looks like that's an "unhandled exception", meaning the cmdlet itself hasn't been coded to recognize and handle that exception. It blew up without ever getting to run it's internal error handling, so the -ErrorAction setting on the cmdlet never came into play.

If you look at this bug 224128, it appears that MergeSort is being used by Mozilla.

#include <string.h>
#include <stdio.h>
int main()
{
   int a,l;
   char str[50],str1[50],str3[100];
   printf("\nEnter a string: ");
   scanf("%s",str);
   str3[0]='\0';
   printf("\nEnter the string which you want to concat with string one: ");
   scanf("%s",str1);
   strcat(str3,str);
   strcat(str3,str1);
   printf("\nThe string is %s\n",str3);
}

Root certificates issued by CAs are just self-signed certificates (which may in turn be used to issue intermediate CA certificates). They have not much special about them, except that they've managed to be imported by default in many browsers or OS trust anchors.

While browsers and some tools are configured to look for the trusted CA certificates (some of which may be self-signed) in location by default, as far as I'm aware the openssl command isn't.

As such, any server that presents the full chain of certificate, from its end-entity certificate (the server's certificate) to the root CA certificate (possibly with intermediate CA certificates) will have a self-signed certificate in the chain: the root CA.

openssl s_client -connect myweb.com:443 -showcerts doesn't have any particular reason to trust Verisign's root CA certificate, and because it's self-signed you'll get "self signed certificate in certificate chain".

If your system has a location with a bundle of certificates trusted by default (I think /etc/pki/tls/certs on RedHat/Fedora and /etc/ssl/certs on Ubuntu/Debian), you can configure OpenSSL to use them as trust anchors, for example like this:

openssl s_client -connect myweb.com:443 -showcerts -CApath /etc/ssl/certs

You have many options. Collating some of the answers above and the accepted answer from this post you can do:
1. df[-df["column"].isin(["value"])]
2. df[~df["column"].isin(["value"])]
3. df[df["column"].isin(["value"]) == False]
4. df[np.logical_not(df["column"].isin(["value"]))]

Note: for option 4 for you'll need to import numpy as np

Update: You can also use the .query method for this too. This allows for method chaining:
5. df.query("column not in @values").
where values is a list of the values that you don't want to include.

I did manage to figure it out:

$order_meta    = get_post_meta($order_id);
$email         = $order_meta["_shipping_email"][0] ?: $order_meta["_billing_email"][0];

I do know know for sure if the shipping email is part of the metadata, but if so I would rather have it than the billing email - at least for my purposes.

Hold down the Option key and click where you'd like the cursor to move, and Terminal rushes the cursor that precise spot.

Thanks a lot @sandeep for his answer.

My problem was that I want to show / hide text on span with mouse click. So by default short text with dots is shown and by clicking long text appears. Clicking again hides that long text and shows short one again.

Quite easy thing to do: just add / remove class with text-overflow:ellipsis.

HTML:

<span class="spanShortText cursorPointer"  onclick="fInventoryShippingReceiving.ShowHideTextOnSpan(this);">Some really long description here</span>

CSS (same as @sandeep with .cursorPointer added)

.spanShortText {
  display: inline-block;
  width: 100px;
  white-space: nowrap;
  overflow: hidden !important;
  text-overflow: ellipsis;
}

.cursorPointer {
  cursor: pointer;
}

JQuery part - basically just removes / adds class cSpanShortText.

  function ShowHideTextOnSpan(element) {
    var cSpanShortText = 'spanShortText';
    var $el = $(element);
    if ($el.hasClass(cSpanShortText)) {
      $el.removeClass(cSpanShortText)
    } else {
      $el.addClass(cSpanShortText);
    }
  }

Instead of loading a stream into a byte array and writing it to the response stream, you should have a look at HttpResponse.TransmitFile

Response.ContentType = "Application/pdf";
Response.TransmitFile(pathtofile);

If you want the PDF to open in a new window you would have to open the downloading page in a new window, for example like this:

<a href="viewpdf.aspx" target="_blank">View PDF</a>

I recently blogged about this. My implementation does not use any string operations during the calculations, which makes it very fast. Conversion to any numeral system with base from 2 to 36 is supported:

/// <summary>
/// Converts the given decimal number to the numeral system with the
/// specified radix (in the range [2, 36]).

    return result;

I've also implemented a fast inverse function in case anyone needs it too: Arbitrary to Decimal Numeral System.

This worked for me. It loops though the classes and checks to see if they are derrived from myInterface

 foreach (Type mytype in System.Reflection.Assembly.GetExecutingAssembly().GetTypes()
                 .Where(mytype => mytype .GetInterfaces().Contains(typeof(myInterface)))) {
    //do stuff
 }

No way. You'll need some dependency injection, i.e. instead of having the obj1 instantiated it should be provided by some factory.

MyObjectFactory factory;

public void setMyObjectFactory(MyObjectFactory factory)
{
  this.factory = factory;
}

void method1()
{
  MyObject obj1 = factory.get();
  obj1.method();
}

Then your test would look like:

@Test
public void testMethod1() throws Exception
{
  MyObjectFactory factory = Mockito.mock(MyObjectFactory.class);
  MyObject obj1 = Mockito.mock(MyObject.class);
  Mockito.when(factory.get()).thenReturn(obj1);
  
  // mock the method()
  Mockito.when(obj1.method()).thenReturn(Boolean.FALSE);

  SomeObject someObject = new SomeObject();
  someObject.setMyObjectFactory(factory);
  someObject.method1();

  // do some assertions
}

Another way of doing this is using Uri.EscapeUriString(stringToEscape).

There are several ways to do this. Both are very simple. Each of the examples works great. You can copy it into your project and test it.

The first method is preferable, the second is a bit outdated, but so far it works too.

1) Solution 1

// File - app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpClientModule } from '@angular/common/http';

import { AppComponent } from './app.component';
import { ProductService } from './product.service';
import { ProductModule } from './product.module';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    HttpClientModule
  ],
  providers: [ProductService, ProductModule],
  bootstrap: [AppComponent]
})
export class AppModule { }



// File - product.service.ts
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

// Importing rxjs
import 'rxjs/Rx';
import { Observable } from 'rxjs/Rx';
import { catchError, tap } from 'rxjs/operators'; // Important! Be sure to connect operators

// There may be your any object. For example, we will have a product object
import { ProductModule } from './product.module';

@Injectable()
export class ProductService{
    // Initialize the properties.
    constructor(private http: HttpClient, private product: ProductModule){}

    // If there are no errors, then the object will be returned with the product data.
    // And if there are errors, we will get into catchError and catch them.
    getProducts(): Observable<ProductModule[]>{
        const url = 'YOUR URL HERE';
        return this.http.get<ProductModule[]>(url).pipe(
            tap((data: any) => {
                console.log(data);
            }),
            catchError((err) => {
                throw 'Error in source. Details: ' + err; // Use console.log(err) for detail
            })
        );
    }
}

2) Solution 2. It is old way but still works.

// File - app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpModule } from '@angular/http';

import { AppComponent } from './app.component';
import { ProductService } from './product.service';
import { ProductModule } from './product.module';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    HttpModule
  ],
  providers: [ProductService, ProductModule],
  bootstrap: [AppComponent]
})
export class AppModule { }



// File - product.service.ts
import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';

// Importing rxjs
import 'rxjs/Rx';
import { Observable } from 'rxjs/Rx';

@Injectable()
export class ProductService{
    // Initialize the properties.
    constructor(private http: Http){}

    // If there are no errors, then the object will be returned with the product data.
    // And if there are errors, we will to into catch section and catch error.
    getProducts(){
        const url = '';
        return this.http.get(url).map(
            (response: Response) => {
                const data = response.json();
                console.log(data);
                return data;
            }
        ).catch(
            (error: Response) => {
                console.log(error);
                return Observable.throw(error);
            }
        );
    }
}

For some reason it didn't work for me. So I had to use something else.

select "option_name_here", :from => "organizationSelect"

worked for me.

select
  Roles
from
  MyTable
where
  Roles.value('(/root/role)[1]', 'varchar(max)') like 'StringToSearchFor'

In case your column is not XML, you need to convert it. You can also use other syntax to query certain attributes of your XML data. Here is an example...

Let's suppose that data column has this:

<Utilities.CodeSystems.CodeSystemCodes iid="107" CodeSystem="2" Code="0001F" CodeTags="-19-"..../>

... and you only want the ones where CodeSystem = 2 then your query will be:

select 
  [data] 
from
  [dbo].[CodeSystemCodes_data]
  
where
  CAST([data] as XML).value('(/Utilities.CodeSystems.CodeSystemCodes/@CodeSystem)[1]', 'varchar(max)') = '2'

These pages will show you more about how to query XML in T-SQL:

Querying XML fields using t-sql

Flattening XML Data in SQL Server

EDIT

After playing with it a little bit more, I ended up with this amazing query that uses CROSS APPLY. This one will search every row (role) for the value you put in your like expression...

Given this table structure:

create table MyTable (Roles XML)

insert into MyTable values
('<root>
   <role>Alpha</role>
   <role>Gamma</role>
   <role>Beta</role>
</root>')

We can query it like this:

select * from 

(select 
       pref.value('(text())[1]', 'varchar(32)') as RoleName
from 
       MyTable CROSS APPLY

       Roles.nodes('/root/role') AS Roles(pref)
)  as Result

where RoleName like '%ga%'

You can check the SQL Fiddle here: http://sqlfiddle.com/#!18/dc4d2/1/0

First, install Homebrew (The missing package manager for macOS) if you haven': Type this in your terminal

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Now you can update your Python to python 3 by this command
brew install python3 && cp /usr/local/bin/python3 /usr/local/bin/python

Python 2 and python 3 can coexist so to open python 3, type python3 instead of python

That's the easiest and the best way.

Just a hint if you have long filenames in utf-8: by default they will be shortened to 20 bytes, so it may happen that the last character might be "cut in half" and therefore unrecognized properly. Then you may want to set the following:

IndexOptions Charset=UTF-8 NameWidth=*

NameWidth setting will prevent shortening your file names, making them properly displayed and readable.

As other users already mentioned, this should be added either in httpd.conf or apache2.conf (if you do have admin rights) or in .htaccess (if you don't).

I use it all the time on hackerrank/leetcode

    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    String  lines = br.readLine();    
        
    String[] strs = lines.trim().split("\\s+");
            
    for (int i = 0; i < strs.length; i++) {
    a[i] = Integer.parseInt(strs[i]);
    }

e.which doesn't work in IE try e.keyCode, also you probably want to use keydown() instead of keypress() if you are targeting IE.

See http://unixpapa.com/js/key.html for more information.

The question is old, but it seems that there are people who have the same concerns.

What do you think of the opinion that 'the alpha property of UIColor and the opacity property of Interface Builder are applied differently in code'?

The two views created in Interface Builder were initially different colors, but had to be the same color when the conditions changed. So, I had to set the background color of one view in code, and set a different value to make the background color of both views the same.

As an actual example, the background color of Interface Builder was 0x121212 and the Opacity value was 80%(in Amani Elsaed's image :: Red: 18, Green: 18, Blue: 18, Hex Color #: [121212], Opacity: 80), In the code, I set the other view a background color of 0x121212 with an alpha value of 0.8.

self.myFuncView.backgroundColor = UIColor(red: 18, green: 18, blue: 18, alpha: 0.8)

extension is

extension UIColor {
    convenience init(red: Int, green: Int, blue: Int, alpha: CGFloat = 1.0) {
        self.init(red: CGFloat(red) / 255.0,
                  green: CGFloat(green) / 255.0,
                  blue: CGFloat(blue) / 255.0,
                  alpha: alpha)
    }
}

However, the actual view was

• 'View with background color specified in Interface Builder': R 0.09 G 0.09 B 0.09 alpha 0.8.
• 'View with background color by code': R 0.07 G 0.07 B 0.07 alpha 0.8

Calculating it,

• 0x12 = 18(decimal)
• 18/255 = 0.07058...
• 255 * 0.09 = 22.95
• 23(decimal) = 0x17

So, I was able to match the colors similarly by setting the UIColor values ??to 17, 17, 17 and alpha 0.8.

self.myFuncView.backgroundColor = UIColor(red: 17, green: 17, blue: 17, alpha: 0.8)

Or can anyone tell me what I'm missing?

Migrate your project to androidX.

dependencies are upgraded to androidX. so if you want to use androidX contents migrate your project to androidX.

With Android Studio 3.2 and higher, you can quickly migrate an existing project to use AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.

Downgrading dependencies may fix your problem this time - but not recommended

input = InputBox("Text:")

If input <> "" Then
   ' Normal
Else
   ' Cancelled, or empty
End If

From MSDN:

If the user clicks Cancel, the function returns a zero-length string ("").

It uses commas as separators. So you can either set sep="," or just use read.csv:

x <- read.csv(file="http://www.irs.gov/file_source/pub/irs-soi/countyinflow1011.csv")
dim(x)
## [1] 113593      9

The error is caused by spaces in some of the values, and unmatched quotes. There are no spaces in the header, so read.table thinks that there is one column. Then it thinks it sees multiple columns in some of the rows. For example, the first two lines (header and first row):

State_Code_Dest,County_Code_Dest,State_Code_Origin,County_Code_Origin,State_Abbrv,County_Name,Return_Num,Exmpt_Num,Aggr_AGI
00,000,96,000,US,Total Mig - US & For,6973489,12948316,303495582

And unmatched quotes, for example on line 1336 (row 1335) which will confuse read.table with the default quote argument (but not read.csv):

01,089,24,033,MD,Prince George's County,13,30,1040

API token is the same as password from API point of view, see source code uses token in place of passwords for the API.

In the accepted answer you get annoying spacing between the visible rows when the expandable row is hidden. You can get rid of that by adding this to css:

.collapse-row.collapsed + tr {
     display: none;
}

'+' is adjacent sibling selector, so if you want your expandable row to be the next row, this selects the next tr following tr named collapse-row.

Here is updated fiddle: http://jsfiddle.net/Nb7wy/2372/

Use the collapse argument to paste:

paste(a,collapse=" ")
[1] "aa bb cc"

Put the elements of the arraylist in the hashMap to count the frequency.

The simplest solution to this problem is that you just need to use \" for space separated arguments when running a shell script:

#!/bin/bash
myFunction() {
  echo $1
  echo $2
  echo $3
}
myFunction "firstString" "\"Hello World\"" "thirdString"

When there are multiple Java installations on your System, the Java version to use as default can be chosen. To do this, execute the following command.

sudo update-alternatives --config java
sudo update-alternatives --config javac
sudo update-alternatives --config javaws

Edit - Manual Java Installation

Download oracle jdk

http://www.oracle.com/technetwork/java/javase/downloads/index.html

Extract zip into desired folder

 e.g  /usr/local/  after extract /usr/local/jdk1.8.0_65

Setup

sudo update-alternatives --install  /usr/bin/java java /usr/local/jdk1.8.0_65/bin/java 1
sudo update-alternatives --install  /usr/bin/javac javac /usr/local/jdk1.8.0_65/bin/javac 1
sudo update-alternatives --install  /usr/bin/javaws javaws /usr/local/jdk1.8.0_65/bin/javaws 1

sudo update-alternatives --set  java /usr/local/jdk1.8.0_65/bin/java
sudo update-alternatives --set  javac /usr/local/jdk1.8.0_65/bin/javac
sudo update-alternatives --set  javaws /usr/local/jdk1.8.0_65/bin/javaws

Edit /etc/environment set JAVA_HOME path for external applications like Eclipse and Idea

According to maven website, the last version to support Java 6 is 3.2.5, and 3.3 and up use Java 7. My hunch is that you're using Maven 3.3 or higher, and should either upgrade to Java 7 (and set proper source/target attributes in your pom) or downgrade maven.

java 1.6.0_21 or later, or so...

$ java -XX:+PrintFlagsFinal -version 2>&1 | grep MaxHeapSize
uintx MaxHeapSize                         := 12660904960      {product}

It looks like the min(1G) has been removed.

Or on Windows using findstr

C:\>java -XX:+PrintFlagsFinal -version 2>&1 | findstr MaxHeapSize

We can use assert here.

def _input(inp_str:str):
    try:
        assert len(inp_str)<=15,print('More than 15 characters present')
        assert all('a'<=i<='z' for i in inp_str),print('Characters other than "a"-"z" are found')
        return inp_str
    except Exception as e:
        pass

_input('abcd')
#abcd
_input('abc d')
#Characters other than "a"-"z" are found
_input('abcdefghijklmnopqrst')
#More than 15 characters present

Maybe you could do

SELECT * FROM table LIMIT 10000 OFFSET FLOOR(RAND() * 190000)

C# 6.0 baby:

This is my solution, although for sure you can use a lot of modules that give you the object as a promise or similar. Anyway, you were missing another callback

function getData(callbackData){
  var http = require('http');
  var str = '';

  var options = {
        host: 'www.random.org',
        path: '/integers/?num=1&min=1&max=10&col=1&base=10&format=plain&rnd=new'
  };

  callback = function(response) {

        response.on('data', function (chunk) {
              str += chunk;
        });

        response.on('end', function () {
              console.log(str);
          callbackData(str);
        });

        //return str;
  }

  var req = http.request(options, callback).end();

  // These just return undefined and empty
  console.log(req.data);
  console.log(str);
}

somewhere else

getData(function(data){
// YOUR CODE HERE!!!
})

Since there were no exact answers to my question, I made some investigation why my code doesn't work when there are other solutions that works, and decided to post what I found to complete the subject.
As it turns out:

"ssh uses direct TTY access to make sure that the password is indeed issued by an interactive keyboard user." sshpass manpage

which answers the question, why the pipes don't work in this case. The obvious solution was to create conditions so that ssh "thought" that it is run in the regular terminal and since it may be accomplished by simple posix functions, it is beyond what simple bash offers.

Here are the steps if you want to do this from Eclipse :

1) Create a folder 'sqlauth' in your C: drive, and copy the dll file sqljdbc_auth.dll to the folder

1) Go to Run> Run Configurations

2) Choose the 'Arguments' tab for your class

3) Add the below code in VM arguments:

-Djava.library.path="C:\\sqlauth"

4) Hit 'Apply' and click 'Run'

Feel free to try other methods .

Try using {} instead of ():

${"file".$i} = file($filelist[$i]);

For your application, nvarchar is fine because the database size is small. Saying "always use nvarchar" is a vast oversimplification. If you're not required to store things like Kanji or other crazy characters, use VARCHAR, it'll use a lot less space. My predecessor at my current job designed something using NVARCHAR when it wasn't needed. We recently switched it to VARCHAR and saved 15 GB on just that table (it was highly written to). Furthermore, if you then have an index on that table and you want to include that column or make a composite index, you've just made your index file size larger.

Just be thoughtful in your decision; in SQL development and data definitions there seems to rarely be a "default answer" (other than avoid cursors at all costs, of course).

The -> operator, which is applied exclusively to pointers, is needed to obtain the specified field or method of the object referenced by the pointer. (this applies also to structs just for their fields)

If you have a variable ptr declared as a pointer you can think of it as (*ptr).field.

A side node that I add just to make pedantic people happy: AS ALMOST EVERY OPERATOR you can define a different semantic of the operator by overloading it for your classes.

Simply convert int to NSString use :

  int x=10;

  NSString *strX=[NSString stringWithFormat:@"%d",x];

In my case this error was specific to the hello-world docker image. I used the nginx image instead of the hello-world image and the error was resolved.

Since ASP.NET MVC 3 RTM is out there is no need for config section for Razor. And these sections can be safely removed.

You can use pandas.DataFrame.mask to add virtually as many conditions as you need:

data = {'a': [1,2,3,4,5], 'b': [6,8,9,10,11]}

d = pd.DataFrame.from_dict(data, orient='columns')
c = {'c1': (2, 'Value1'), 'c2': (3, 'Value2'), 'c3': (5, d['b'])}

d['new'] = np.nan
for value in c.values():
    d['new'].mask(d['a'] == value[0], value[1], inplace=True)

d['new'] = d['new'].fillna('Else')
d

Output:

    a   b   new
0   1   6   Else
1   2   8   Value1
2   3   9   Value2
3   4   10  Else
4   5   11  11

Years ago MSIE 5 or 5.5 (and probably both) had some serious issue with a "-" in the HTML block if you can believe it. Alhough it's not directly related, ever since we've stored an MD5 hash (containing letters and numbers only) in the cookie to look up everything else in server-side database.

This function compares two arrays of arbitrary shape and dimesionality:

function equals(a1, a2) {

    if (!Array.isArray(a1) || !Array.isArray(a2)) {
        throw new Error("Arguments to function equals(a1, a2) must be arrays.");
    }

    if (a1.length !== a2.length) {
        return false;
    }

    for (var i=0; i<a1.length; i++) {
        if (Array.isArray(a1[i]) && Array.isArray(a2[i])) {
            if (equals(a1[i], a2[i])) {
                continue;
            } else {
                return false;
            }
        } else {
            if (a1[i] !== a2[i]) {
                return false;
            }
        }
    }

    return true;
}

It's really late now but I made a quick script which works for Windows, Mac and Linux, simply by using each command line:

import os, platform

def close():
    if platform.system() == "Windows":
        print("Press any key to exit . . .")
        os.system("pause>nul")
        exit()
    
    elif platform.system() == "Linux":
        os.system("read -n1 -r -p \"Press any key to exit . . .\" key")
        exit()
    
    elif platform.system() == "Darwin":
        print("Press any key to exit . . .")
        os.system("read -n 1 -s -p \"\"")
        exit()
    
    else:
        exit()

It uses only inbuilt functions, and should work for all three (although I've only tested Windows and Linux...).

this solution worked for me:

var oldURL = "";
var currentURL = window.location.href;
function checkURLchange(currentURL){
    if(currentURL != oldURL){
        alert("url changed!");
        oldURL = currentURL;
    }

    oldURL = window.location.href;
    setTimeout(function() {
        checkURLchange(window.location.href);
    }, 1000);
}

checkURLchange();

Includes are not directly supported in YAML as far as I know, you will have to provide a mechanism yourself however, this is generally easy to do.

I have used YAML as a configuration language in my python apps, and in this case often define a convention like this:

>>> main.yml <<<
includes: [ wibble.yml, wobble.yml]

Then in my (python) code I do:

import yaml
cfg = yaml.load(open("main.yml"))
for inc in cfg.get("includes", []):
   cfg.update(yaml.load(open(inc)))

The only down side is that variables in the includes will always override the variables in main, and there is no way to change that precedence by changing where the "includes: statement appears in the main.yml file.

On a slightly different point, YAML doesn't support includes as its not really designed as as exclusively as a file based mark up. What would an include mean if you got it in a response to an AJAX request?

try this code worked for me

SELECT user_display_image AS user_image,
       user_display_name AS user_name,
       invitee_phone,
       (CASE WHEN invitee_status = 1 THEN "attending"
             WHEN invitee_status = 2 THEN "unsure"
             WHEN invitee_status = 3 THEN "declined"
             WHEN invitee_status = 0 THEN "notreviwed"
       END) AS invitee_status
  FROM your_table

Conditionals work if they're structured correctly, I ran into this issue and figured it out.

For conditionals, the tag before else has to be paired with the end tag of the previous if otherwise the statements will evaluate separately and produce an error.

ERROR!

<% if(true){ %>
   <h1>foo</h1>
<% } %>
<% else{ %>
   <h1>bar</h1>
 <% } %>

Correct

<% if(true){ %>
   <h1>foo</h1>
 <% } else{ %>  
   <h1>bar</h1>
<% } %>

hope this helped.

Have you tried adding a configsection handler to your app.config? e.g.

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>

diff(1) is not the answer, but comm(1) is.

NAME
       comm - compare two sorted files line by line

SYNOPSIS
       comm [OPTION]... FILE1 FILE2

...

       -1     suppress lines unique to FILE1

       -2     suppress lines unique to FILE2

       -3     suppress lines that appear in both files

So

comm -2 -3 file1 file2 > file3

The input files must be sorted. If they are not, sort them first. This can be done with a temporary file, or...

comm -2 -3 <(sort file1) <(sort file2) > file3

provided that your shell supports process substitution (bash does).

== and != do not take into account the data type of the variables you compare. So these would all return true:

'0'   == 0
false == 0
NULL  == false

=== and !== do take into account the data type. That means comparing a string to a boolean will never be true because they're of different types for example. These will all return false:

'0'   === 0
false === 0
NULL  === false

You should compare data types for functions that return values that could possibly be of ambiguous truthy/falsy value. A well-known example is strpos():

// This returns 0 because F exists as the first character, but as my above example,
// 0 could mean false, so using == or != would return an incorrect result
var_dump(strpos('Foo', 'F') != false);  // bool(false)
var_dump(strpos('Foo', 'F') !== false); // bool(true), it exists so false isn't returned

Add this line above you Query

SET IDENTITY_INSERT tbl_content ON

FragmentActivity is part of the support library, while Activity is the framework's default class. They are functionally equivalent.

You should always use FragmentActivity and android.support.v4.app.Fragment instead of the platform default Activity and android.app.Fragment classes. Using the platform defaults mean that you are relying on whatever implementation of fragments is used in the device you are running on. These are often multiple years old, and contain bugs that have since been fixed in the support library.

From http://www.regular-expressions.info/charclass.html :

Note that the only special characters or metacharacters inside a character class are the closing bracket (]), the backslash (\\), the caret (^) and the hyphen (-). The usual metacharacters are normal characters inside a character class, and do not need to be escaped by a backslash. To search for a star or plus, use [+*]. Your regex will work fine if you escape the regular metacharacters inside a character class, but doing so significantly reduces readability.

To include a backslash as a character without any special meaning inside a character class, you have to escape it with another backslash. [\\x] matches a backslash or an x. The closing bracket (]), the caret (^) and the hyphen (-) can be included by escaping them with a backslash, or by placing them in a position where they do not take on their special meaning. I recommend the latter method, since it improves readability. To include a caret, place it anywhere except right after the opening bracket. [x^] matches an x or a caret. You can put the closing bracket right after the opening bracket, or the negating caret. []x] matches a closing bracket or an x. [^]x] matches any character that is not a closing bracket or an x. The hyphen can be included right after the opening bracket, or right before the closing bracket, or right after the negating caret. Both [-x] and [x-] match an x or a hyphen.

What language are you writing the regex in?

Use static method valueOf(String) defined for each enum.

For example if you have enum MyEnum you can say MyEnum.valueOf("foo")

you can use the pow method from the Math class. The following code will output 2 raised to 3 (8)

System.out.println(Math.pow(2, 3));

From PEP 249, which is usually implemented by Python database APIs:

Cursor Objects should respond to the following methods and attributes:

[…]

.rowcount
This read-only attribute specifies the number of rows that the last .execute*() produced (for DQL statements like 'select') or affected (for DML statements like 'update' or 'insert').

But be careful—it goes on to say:

The attribute is -1 in case no .execute*() has been performed on the cursor or the rowcount of the last operation is cannot be determined by the interface. [7]

Note:
Future versions of the DB API specification could redefine the latter case to have the object return None instead of -1.

So if you've executed your statement, and it works, and you're certain your code will always be run against the same version of the same DBMS, this is a reasonable solution.

I consider Ashwin's answer to be the most correct, my old answer is below.

docker run -dti foo bash

You can then enter the container and run bash with

docker exec -ti ID_of_foo bash

No need to install sshd :)

public static void Each<T>(this IEnumerable<T> items, Action<T> action) {
foreach (var item in items) {
    action(item);
} }

... and call it thusly:

myList.Each(x => { x.Enabled = false; });

In my case I had to rename the table with name user. I renamed it for example users and it worked.

I disagree with the document.write technique (see suggestion of Vahan Margaryan). I like document.getElementsByTagName('head')[0].appendChild(...) (see suggestion of Matt Ball), but there is one important issue: the script execution order.

Recently, I have spent a lot of time reproducing one similar issue, and even the well-known jQuery plugin uses the same technique (see src here) to load the files, but others have also reported the issue. Imagine you have JavaScript library which consists of many scripts, and one loader.js loads all the parts. Some parts are dependent on one another. Imagine you include another main.js script per <script> which uses the objects from loader.js immediately after the loader.js. The issue was that sometimes main.js is executed before all the scripts are loaded by loader.js. The usage of $(document).ready(function () {/*code here*/}); inside of main.js script does not help. The usage of cascading onload event handler in the loader.js will make the script loading sequential instead of parallel, and will make it difficult to use main.js script, which should just be an include somewhere after loader.js.

By reproducing the issue in my environment, I can see that **the order of execution of the scripts in Internet Explorer 8 can differ in the inclusion of the JavaScript*. It is a very difficult issue if you need include scripts that are dependent on one another. The issue is described in Loading Javascript files in parallel, and the suggested workaround is to use document.writeln:

document.writeln("<script type='text/javascript' src='Script1.js'></script>");
document.writeln("<script type='text/javascript' src='Script2.js'></script>");

So in the case of "the scripts are downloaded in parallel but executed in the order they're written to the page", after changing from document.getElementsByTagName('head')[0].appendChild(...) technique to document.writeln, I had not seen the issue anymore.

So I recommend that you use document.writeln.

UPDATED: If somebody is interested, they can try to load (and reload) the page in Internet Explorer (the page uses the document.getElementsByTagName('head')[0].appendChild(...) technique), and then compare with the fixed version used document.writeln. (The code of the page is relatively dirty and is not from me, but it can be used to reproduce the issue).

You should consider using a dict type instead of pre-initialized list. The cost of a dictionary look-up is small and comparable to the cost of accessing arbitrary list element.

And when using a mapping you can write:

aDict = {}
aDict[100] = fetchElement()
putElement(fetchElement(), fetchPosition(), aDict)

And the putElement function can store item at any given position. And if you need to check if your collection contains element at given index it is more Pythonic to write:

if anIndex in aDict:
    print "cool!"

Than:

if not myList[anIndex] is None:
    print "cool!"

Since the latter assumes that no real element in your collection can be None. And if that happens - your code misbehaves.

And if you desperately need performance and that's why you try to pre-initialize your variables, and write the fastest code possible - change your language. The fastest code can't be written in Python. You should try C instead and implement wrappers to call your pre-initialized and pre-compiled code from Python.

Natural Number (Strings) Quick Sort

Just to pile onto the topic. Normally, if you sort strings with numbers you'll get something like this:

    Text1
    Text10
    Text100
    Text11
    Text2
    Text20

But you really want it to recognize the numerical values and be sorted like

    Text1
    Text2
    Text10
    Text11
    Text20
    Text100

Here's how to do it...

Note:

• I stole the Quick Sort from the internet a long time ago, not sure where now...
• I translated the CompareNaturalNum function which was originally written in C from the internet as well.
• Difference from other Q-Sorts: I don't swap the values if the BottomTemp = TopTemp

Natural Number Quick Sort

Public Sub QuickSortNaturalNum(strArray() As String, intBottom As Integer, intTop As Integer)
Dim strPivot As String, strTemp As String
Dim intBottomTemp As Integer, intTopTemp As Integer

    intBottomTemp = intBottom
    intTopTemp = intTop

    strPivot = strArray((intBottom + intTop) \ 2)

    Do While (intBottomTemp <= intTopTemp)
        ' < comparison of the values is a descending sort
        Do While (CompareNaturalNum(strArray(intBottomTemp), strPivot) < 0 And intBottomTemp < intTop)
            intBottomTemp = intBottomTemp + 1
        Loop
        Do While (CompareNaturalNum(strPivot, strArray(intTopTemp)) < 0 And intTopTemp > intBottom) '
            intTopTemp = intTopTemp - 1
        Loop
        If intBottomTemp < intTopTemp Then
            strTemp = strArray(intBottomTemp)
            strArray(intBottomTemp) = strArray(intTopTemp)
            strArray(intTopTemp) = strTemp
        End If
        If intBottomTemp <= intTopTemp Then
            intBottomTemp = intBottomTemp + 1
            intTopTemp = intTopTemp - 1
        End If
    Loop

    'the function calls itself until everything is in good order
    If (intBottom < intTopTemp) Then QuickSortNaturalNum strArray, intBottom, intTopTemp
    If (intBottomTemp < intTop) Then QuickSortNaturalNum strArray, intBottomTemp, intTop
End Sub

You can use method getDate():

$('#calendar').datepicker({
    dateFormat: 'yy-m-d',
    inline: true,
    onSelect: function(dateText, inst) { 
        var date = $(this).datepicker('getDate'),
            day  = date.getDate(),  
            month = date.getMonth() + 1,              
            year =  date.getFullYear();
        alert(day + '-' + month + '-' + year);
    }
});

You can decode it to str with receive.decode('utf_8').

This error message can be very confusing and the solution can be surprisingly primitive.

In my case: Oracle stored procedure sends recordset to MS Excel via "Provider=OraOLEDB.Oracle;Data Source= ...etc" .

The problem was a number of decimal numbers in the Oracle data column sent to Excel 2010. When I used Oracle SQL query ROUND(grosssales_eur,2) AS grosssales_eur, it worked fine.

I just had the same problem/question and solved it like this (only client code):

var io = io.connect('localhost');

io.on('connect', function () {
    console.log(this.socket.sessionid);
});

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

I suggest to look at Dan Abramov (one of the React core maintainers) answer here:

I think you're making it more complicated than it needs to be.

function Example() {
  const [data, dataSet] = useState<any>(null)

  useEffect(() => {
    async function fetchMyAPI() {
      let response = await fetch('api/data')
      response = await response.json()
      dataSet(response)
    }

    fetchMyAPI()
  }, [])

  return <div>{JSON.stringify(data)}</div>
}

Longer term we'll discourage this pattern because it encourages race conditions. Such as — anything could happen between your call starts and ends, and you could have gotten new props. Instead, we'll recommend Suspense for data fetching which will look more like

const response = MyAPIResource.read();

and no effects. But in the meantime you can move the async stuff to a separate function and call it.

You can read more about experimental suspense here.

If you want to use functions outside with eslint.

 function OutsideUsageExample() {
  const [data, dataSet] = useState<any>(null)

  const fetchMyAPI = useCallback(async () => {
    let response = await fetch('api/data')
    response = await response.json()
    dataSet(response)
  }, [])

  useEffect(() => {
    fetchMyAPI()
  }, [fetchMyAPI])

  return (
    <div>
      <div>data: {JSON.stringify(data)}</div>
      <div>
        <button onClick={fetchMyAPI}>manual fetch</button>
      </div>
    </div>
  )
}

If you will use useCallback, look at example of how it works useCallback. Sandbox.

import React, { useState, useEffect, useCallback } from "react";

export default function App() {
  const [counter, setCounter] = useState(1);

  // if counter is changed, than fn will be updated with new counter value
  const fn = useCallback(() => {
    setCounter(counter + 1);
  }, [counter]);

  // if counter is changed, than fn will not be updated and counter will be always 1 inside fn
  /*const fnBad = useCallback(() => {
      setCounter(counter + 1);
    }, []);*/

  // if fn or counter is changed, than useEffect will rerun
  useEffect(() => {
    if (!(counter % 2)) return; // this will stop the loop if counter is not even

    fn();
  }, [fn, counter]);

  // this will be infinite loop because fn is always changing with new counter value
  /*useEffect(() => {
    fn();
  }, [fn]);*/

  return (
    <div>
      <div>Counter is {counter}</div>
      <button onClick={fn}>add +1 count</button>
    </div>
  );
}

Mac users with the Postgres app may want to open the application (spotlight search Postgres or find the elephant icon in your menu bar). Therein you may see a red X with the message: "Stale postmaster.pid file". Unfortunately a spotlight search won't show the location of this file. Click "Server Settings...", and in the dialog box that opens, click the "Show" button to open the Data Directory. Navigate one folder in (for me it was "var-10"), and delete the postmaster.pid file.

Go back to the Postgres app and click the Start button. That red X should turn into a green check mark with the message "Running". Now you should be able to successfully run Rails commands like rails server in the terminal.

Try trimming the string to make sure there is no extra white space:

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);

Also use c.moveToFirst() like @thinksteep mentioned.

This is a complete code for select statements.

SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
    do {
        // Passing values 
        String column1 = c.getString(0);
        String column2 = c.getString(1);
        String column3 = c.getString(2); 
        // Do something Here with values
    } while(c.moveToNext());
}
c.close();
db.close();

You can also try dropping the index column if it is not needed to compare:

print(df1.reset_index(drop=True) == df2.reset_index(drop=True))

I have used this same technique in a unit test like so:

from pandas.util.testing import assert_frame_equal

assert_frame_equal(actual.reset_index(drop=True), expected.reset_index(drop=True))

Here is another example showing the use of gather from tidyr. You can select the columns to gather either by removing them individually (as I do here), or by including the years you want explicitly.

Note that, to handle the commas (and X's added if check.names = FALSE is not set), I am also using dplyr's mutate with parse_number from readr to convert the text values back to numbers. These are all part of the tidyverse and so can be loaded together with library(tidyverse)

wide %>%
  gather(Year, Value, -Code, -Country) %>%
  mutate(Year = parse_number(Year)
         , Value = parse_number(Value))

Returns:

   Code     Country Year Value
1   AFG Afghanistan 1950 20249
2   ALB     Albania 1950  8097
3   AFG Afghanistan 1951 21352
4   ALB     Albania 1951  8986
5   AFG Afghanistan 1952 22532
6   ALB     Albania 1952 10058
7   AFG Afghanistan 1953 23557
8   ALB     Albania 1953 11123
9   AFG Afghanistan 1954 24555
10  ALB     Albania 1954 12246

If the attribute you want to change doesn't exist or has been accidentally removed, then an exception occurs. I suggest you first create a new attribute and send it to a function like the following:

private void SetAttrSafe(XmlNode node,params XmlAttribute[] attrList)
    {
        foreach (var attr in attrList)
        {
            if (node.Attributes[attr.Name] != null)
            {
                node.Attributes[attr.Name].Value = attr.Value;
            }
            else
            {
                node.Attributes.Append(attr);
            }
        }
    }

Usage:

   XmlAttribute attr = dom.CreateAttribute("name");
   attr.Value = value;
   SetAttrSafe(node, attr);

The jQuery constructor accepts a 2nd parameter called context which can be used to override the context of the selection.

jQuery("img", this);

Which is the same as using .find() like this:

jQuery(this).find("img");

If the imgs you desire are only direct descendants of the clicked element, you can also use .children():

jQuery(this).children("img");

Since you should focus on usability and generalities in CSS, rather than use an id to point to a specific layout element (which results in huge or multiple css files) you should probably instead use a true class in your linked .css file:

.hidden {
visibility: hidden;
display: none;
}

or for the minimalist:

.hidden {
display: none;
}

Now you can simply apply it via:

<div class="hidden"> content </div>

You need to use the target selector.

Here is a fiddle with another example: http://jsfiddle.net/YYPKM/3/

I guess you have some conflict with other package. For me it was six. So you need to use a command like this:

pip install google-api-python-client --upgrade --ignore-installed six

or

pip install --ignore-installed six

viewNoteDateMonth.text  = [[displayDate objectAtIndex:2] uppercaseString];

Documentation: http://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html#//apple_ref/occ/instm/NSString/uppercaseString

You can also use lowercaseString and capitalizedString

A clean way to do this using modern JavaScript is as follows:

const array = [
  { name: "something", value: "something" },
  { name: "somethingElse", value: "something else" },
];

const newObject = Object.assign({}, ...array.map(item => ({ [item.name]: item.value })));

// >> { something: "something", somethingElse: "something else" }

As simple as you can use const adults = family.filter(({ age }) => age > 18 );

const family =[{"name":"Jack",  "age": 26},_x000D_
              {"name":"Jill",  "age": 22},_x000D_
              {"name":"James", "age": 5 },_x000D_
              {"name":"Jenny", "age": 2 }];_x000D_
_x000D_
const adults = family.filter(({ age }) => age > 18 );_x000D_
_x000D_
console.log(adults)

In this case that you know that you have all items in the first place on array you can parse the string to JArray and then parse the first item using JObject.Parse

var  jsonArrayString = @"
[
  {
    ""country"": ""India"",
    ""city"": ""Mall Road, Gurgaon"",
  },
  {
    ""country"": ""India"",
    ""city"": ""Mall Road, Kanpur"",
  }
]";
JArray jsonArray = JArray.Parse(jsonArrayString);
dynamic data = JObject.Parse(jsonArray[0].ToString());

Weak entity exists to solve the multi-valued attributes problem.

There are two types of multi-valued attributes. One is the simply many values for an objects such as a "hobby" as an attribute for a student. The student can have many different hobbies. If we leave the hobbies in the student entity set, "hobby" would not be unique any more. We create a separate entity set as hobby. Then we link the hobby and the student as we need. The hobby entity set is now an associative entity set. As to whether it is weak or not, we need to check whether each entity has enough unique identifiers to identify it. In many opinion, a hobby name can be enough to identify it.

The other type of multi-valued attribute problem does need a weak entity to fix it. Let's say an item entity set in a grocery inventory system. Is the item a category item or the actually item? It is an important question, because a customer can buy the same item at one time and at a certain amount, but he can also buy the same item at a different time with a different amount. Can you see it the same item but of different objects. The item now is a multi-valued attribute. We solve it by first separate the category item with the actual item. The two are now different entity sets. Category item has descriptive attributes of the item, just like the item you usually think of. Actual item can not have descriptive attributes any more because we can not have redundant problem. Actual item can only have date time and amount of the item. You can link them as you need. Now, let's talk about whether one is a weak entity of the other. The descriptive attributes are more than enough to identify each entity in the category item entity set. The actual item only has date time and amount. Even if we pull out all the attributes in a record, we still cannot identify the entity. Think about it is just time and amount. The actual item entity set is a weak entity set. We identify each entity in the set with the help of duplicate prime key from the category item entity set.

You can try this:

SELECT * FROM MYTABLE WHERE DATE BETWEEN '03/10/2014 06:25:00' and '03/12/2010 6:25:00'

This worked for me.

Setup log4j as normal. Then use this code:

    // LOGGING 
    LoggingOutInterceptor loi = new LoggingOutInterceptor(); 
    loi.setPrettyLogging(true); 
    LoggingInInterceptor lii = new LoggingInInterceptor(); 
    lii.setPrettyLogging(true); 

    org.apache.cxf.endpoint.Client client = org.apache.cxf.frontend.ClientProxy.getClient(isalesService); 
    org.apache.cxf.endpoint.Endpoint cxfEndpoint = client.getEndpoint(); 

    cxfEndpoint.getOutInterceptors().add(loi); 
    cxfEndpoint.getInInterceptors().add(lii);

You should define source code encoding, add this to the top of your script:

# -*- coding: utf-8 -*-

The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:

import sys
print sys.getdefaultencoding()

Also see:

• Why declare unicode by string in python?
• Changing default encoding of Python?
• Correct way to define Python source code encoding

Dumb question/answer perhaps, but have you tried dd/MM/yyyy? Note the capitalization.

mm is for minutes with a leading zero. So I doubt that's what you want.

Another way to run jar files with a click/double-click, is to prepend "-jar " to the file's name. For example, you would rename the file MyJar.jar to -jar MyJar.jar.

You must have the .class files associated with java.exe, of course. This might not work in all cases, but it has worked most times for me.

The following script reads from a file named "testonthis" line by line and then compares each line with a simple string, a string with special characters and a regular expression. If it doesn't match, then the script will print the line, otherwise not.

Space in Bash is so much important. So the following will work:

[ "$LINE" != "table_name" ] 

But the following won't:

["$LINE" != "table_name"] 

So please use as is:

cat testonthis | while read LINE
do
if [ "$LINE" != "table_name" ] && [ "$LINE" != "--------------------------------" ] && [[ "$LINE" =~ [^[:space:]] ]] && [[ "$LINE" != SQL* ]]; then
echo $LINE
fi
done

C++11 lambdas can't be templated as stated in other answers but decltype() seems to help when using a lambda within a templated class or function.

#include <iostream>
#include <string>

using namespace std;

template<typename T>
void boring_template_fn(T t){
    auto identity = [](decltype(t) t){ return t;};
    std::cout << identity(t) << std::endl;
}

int main(int argc, char *argv[]) {
    std::string s("My string");
    boring_template_fn(s);
    boring_template_fn(1024);
    boring_template_fn(true);
}

Prints:

My string
1024
1

I've found this technique is helps when working with templated code but realize it still means lambdas themselves can't be templated.

If you're open to a Perl solution, here one similar to fedorqui's awk solution:

perl -F/ -lane 'print $F[-1]' input

-F/ specifies / as the field separator
$F[-1] is the last element in the @F autosplit array

like this: put intro outside your document ready, Good discussion here: http://forum.jquery.com/topic/how-do-i-declare-a-global-variable-in-jquery @thecodeparadox is awesomely fast :P anyways!

 var intro;

$(document).ready(function() {



    if ($('.intro_check').is(':checked')) {
        intro = true;
        $('.intro').wrap('<div class="disabled"></div>');
    };

    $('.intro_check').change(function(){
        if(this.checked) {
            intro = false;
            $('.enabled').removeClass('enabled').addClass('disabled');
        } else {
            intro = true;
            if($('.intro').exists()) {
                $('.disabled').removeClass('disabled').addClass('enabled'); 
            } else {
                $('.intro').wrap('<div class="disabled"></div>');
            }
        }
    });
});

The same as David's, but without attr()

$('<input>', {
    type: 'hidden',
    id: 'foo',
    name: 'foo',
    value: 'bar'
}).appendTo('form');

Unfortunately, all of these solutions rely on specifying a fixed width. Since the tables are generated dynamically (statistical results pulled from a database), the width can not be known in advance.

The desired result can be achieved by wrapping the two tables within another table:

<table align="center"><tr><td>
//code for table on the left
</td><td>
//code for table on the right
</td></tr></table>

and the result is a perfectly centered pair of tables that responds fluidly to arbitrary widths and page (re)sizes (and the align="center" table attribute could be hoisted out into an outer div with margin autos).

I conclude that there are some layouts that can only be achieved with tables.

If this error occurs when running a Gradle (or Maven) task, you need to modify that build tool configuration to point to your installation of Java JDK 1.8 following this route:

File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle

There you check the Linked Gradle project is the one you are working on and select the Gradle JVM (You missed this when you imported the gradle project into IntelliJ)

Remember when importing a Gradle (or Maven) project to set the target JVM correctly here:

In Chrome, use JSONView to view formatted JSON.

To view "local" *.json files: - after install You must open the Extensions option from Window menu. - Check box next to "Allow Access to File URLs" - note that save is automatic (i.e. no explicit save necessary)

Re-open the *.json file and it should be formatted.

you can get a files modified date using vbscript too

Set objFS=CreateObject("Scripting.FileSystemObject")
Set objArgs = WScript.Arguments
strFile= objArgs(0)
WScript.Echo objFS.GetFile(strFile).DateLastModified

save the above as mygetdate.vbs and on command line

c:\test> cscript //nologo mygetdate.vbs myfile

This worked for me :

  e.Row.Cells["cell no "].HorizontalAlign = HorizontalAlign.Center;

But 'css text-align = center ' didn't worked for me

hope it will help you

The following Link has explained complete details about how to back sql server 2008 database using c#

Sql Database backup can be done using many way. You can either use Sql Commands like in the other answer or have create your own class to backup data.

But these are different mode of backup.

1. Full Database Backup
2. Differential Database Backup
3. Transaction Log Backup
4. Backup with Compression

But the disadvantage with this method is that it needs your sql management studio to be installed on your client system.

It has a tricky situation: If you submit a post form, then Chrome will open a new tab to send the request. It's right until now, but if it triggers an event to download file(s), this tab will close immediately so that you cannot capture this request in the Dev Tool.

Solution: Before submitting the post form, you need to cut off your network, which makes the request cannot send successfully so that the tab will not be closed. And then you can capture the request message in the Chrome Devtool(Refreshing the new tab if necessary)

I'm on Mojave with Python 2.7 and after pip install --user jupyter the binary went here:

/Users/me/Library/Python//2.7/bin/jupyter

From the standard (p. ii):

It is expected that other standards will refer to this one, strictly adhering to the JSON text format, while imposing restrictions on various encoding details. Such standards may require specific behaviours. JSON itself specifies no behaviour.

Further down in the standard (p. 2), the specification for a JSON object:

An object structure is represented as a pair of curly bracket tokens surrounding zero or more name/value pairs. A name is a string. A single colon token follows each name, separating the name from the value. A single comma token separates a value from a following name.

It does not make any mention of duplicate keys being invalid or valid, so according to the specification I would safely assume that means they are allowed.

That most implementations of JSON libraries do not accept duplicate keys does not conflict with the standard, because of the first quote.

Here are two examples related to the C++ standard library. When deserializing some JSON object into a std::map it would make sense to refuse duplicate keys. But when deserializing some JSON object into a std::multimap it would make sense to accept duplicate keys as normal.

No, APK Manager decompiles the .dex file into .smali and binary .xml to human readable xml.

The sequence (based on APK Manager 4.9) is 22 to select the package, and then 9 to decompile it. If you press 1 instead of 9, then you will just unpack it (useful only if you want to exchange .png images).

There is no tool available to decompile back to .java files and most probably it won't be any. There is an alternative, which is using dex2jar to transform the dex file in to a .class file, and then use a jar decompiler (such as the free jd-gui) to plain text java. The process is far from optimal, though, and it won't generate working code, but it's decent enough to be able to read it.

dex2jar: https://github.com/pxb1988/dex2jar

Edit: I knew there was somewhere here in SO a question with very similar answers... decompiling DEX into Java sourcecode

If you have Excel 2007 or later use COUNTIFS with an "S" on the end, i.e.

=COUNTIFS(B2:B292,">10",B2:B292,"<10000")

You may need to change commas , to semi-colons ;

In earlier versions of excel use SUMPRODUCT like this

=SUMPRODUCT((B2:B292>10)*(B2:B292<10000))

Note: if you want to include exactly 10 change > to >= - similarly with 10000, change < to <=

You're setting overflow: hidden. This will hide anything that's too large for the <div>, meaning scrollbars won't be shown. Give your <div> an explicit width and/or height, and change overflow to auto:

.scroll {
   width: 200px;
   height: 400px;
   overflow: scroll;
}

If you only want to show a scrollbar if the content is longer than the <div>, change overflow to overflow: auto. You can also only show one scrollbar by using overflow-y or overflow-x.

Cast the operands to floats:

float ans = (float)a / (float)b;

I review your url in use:

https://www.facebook.com/sharer/sharer.php?s=100&p[title]=EXAMPLE&p[summary]=EXAMPLE&p[url]=EXAMPLE&p[images][0]=EXAMPLE

and see this differences:

1. The sharer URL not is same.
2. The strings are in different order. ( Do not know if this affects ).

I use this URL string:

http://www.facebook.com/sharer.php?s=100&p[url]=http://www.example.com/&p[images][0]=/images/image.jpg&p[title]=Title&p[summary]=Summary

In the "title" and "summary" section, I use the php function urlencode(); like this:

<?php echo urlencode($detail->title); ?>

And working fine for me.

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

Unfortunately, you can only turn on all invisible (whitespace) characters at the same time. I suggest you file an enhancement request but I doubt they will pick it up.

The text component in Eclipse is very complicated as it is and they are not keen on making them even worse.

[UPDATE] This has been fixed in Eclipse 3.7: Go to Window > Preferences > General > Editors > Text Editors

Click on the link "whitespace characters" to fine tune what should be shown.

Kudos go to John Isaacks

Try this:

var matches = url.match(/^https?\:\/\/([^\/?#]+)(?:[\/?#]|$)/i);
var domain = matches && matches[1];  // domain will be null if no match is found

If you want to exclude the port from your result, use this expression instead:

/^https?\:\/\/([^\/:?#]+)(?:[\/:?#]|$)/i

Edit: To prevent specific domains from matching, use a negative lookahead. (?!youtube.com)

/^https?\:\/\/(?!(?:www\.)?(?:youtube\.com|youtu\.be))([^\/:?#]+)(?:[\/:?#]|$)/i

In Rails 4 all I had to do was the def change

def change
  rename_table :old_table_name, :new_table_name
end

And all of my indexes were taken care of for me. I did not need to manually update the indexes by removing the old ones and adding new ones.

And it works using the change for going up or down in regards to the indexes as well.

In Visual Studio 2019- Tools > Command Line > Developer Command Prompt.enter image description here

Kotlin static and constant value & method declare

    return v1 + v2
}

}

Access value anywhere

val value = MyConstant.PI
val value = MyConstant.sumValue(10,5)

In general I fully agree with Jason's use of css selector, but in some cases you may not want to change the css, e.g. when using a 3rd party css-template, and rather prefer to add/remove a class on the element.

The following sample shows a simple way of adding/removing a class on ng-mouseenter/mouseleave:

<div ng-app>
  <div 
    class="italic" 
    ng-class="{red: hover}"
    ng-init="hover = false"
    ng-mouseenter="hover = true"
    ng-mouseleave="hover = false">
      Test 1 2 3.
  </div>
</div>

with some styling:

.red {
  background-color: red;
}

.italic {
  font-style: italic;
  color: black;
}

See running example here: jsfiddle sample

Styling on hovering is a view concern. Although the solution above sets a "hover" property in the current scope, the controller does not need to be concerned about this.

You can do this in the storyboard / xib editor as well. Just set Seperator to none.

.loc and .iloc are used for indexing, i.e., to pull out portions of data. In essence, the difference is that .loc allows label-based indexing, while .iloc allows position-based indexing.

If you get confused by .loc and .iloc, keep in mind that .iloc is based on the index (starting with i) position, while .loc is based on the label (starting with l).

.loc

.loc is supposed to be based on the index labels and not the positions, so it is analogous to Python dictionary-based indexing. However, it can accept boolean arrays, slices, and a list of labels (none of which work with a Python dictionary).

iloc

.iloc does the lookup based on index position, i.e., pandas behaves similarly to a Python list. pandas will raise an IndexError if there is no index at that location.

Examples

The following examples are presented to illustrate the differences between .iloc and .loc. Let's consider the following series:

>>> s = pd.Series([11, 9], index=["1990", "1993"], name="Magic Numbers")
>>> s
1990    11
1993     9
Name: Magic Numbers , dtype: int64

.iloc Examples

>>> s.iloc[0]
11
>>> s.iloc[-1]
9
>>> s.iloc[4]
Traceback (most recent call last):
    ...
IndexError: single positional indexer is out-of-bounds
>>> s.iloc[0:3] # slice
1990 11
1993  9
Name: Magic Numbers , dtype: int64
>>> s.iloc[[0,1]] # list
1990 11
1993  9
Name: Magic Numbers , dtype: int64

.loc Examples

>>> s.loc['1990']
11
>>> s.loc['1970']
Traceback (most recent call last):
    ...
KeyError: ’the label [1970] is not in the [index]’
>>> mask = s > 9
>>> s.loc[mask]
1990 11
Name: Magic Numbers , dtype: int64
>>> s.loc['1990':] # slice
1990    11
1993     9
Name: Magic Numbers, dtype: int64

Because s has string index values, .loc will fail when indexing with an integer:

>>> s.loc[0]
Traceback (most recent call last):
    ...
KeyError: 0

You can compare an array like the below mentioned if the array has some values

it('should check if the array are equal', function() {
        var mockArr = [1, 2, 3];
        expect(mockArr ).toEqual([1, 2, 3]);
 });

But if the array that is returned from some function has more than 1 elements and all are zero then verify by using

expect(mockArray[0]).toBe(0);

This works for SQL Server Management Studio v18.0

The file "SqlStudio.bin" doesn't seem to exist any longer. Instead my settings are all stored in this file:

C:\Users\*********\AppData\Roaming\Microsoft\SQL Server Management Studio\18.0\UserSettings.xml

• Open it in any Texteditor like Notepad++
• ctrl+f for the username to be removed
• then delete the entire <Element>.......</Element> block that surrounds it.

$suborder['payment_date'] = Carbon::parse($item['created_at'])->format('M d Y');

Surprisingly enough, what worked for me on Debian Linux was ONLY:

adb kill-server

WITHOUT STARTING IT AGAIN!!!

The device appeared in the Android Studio as soon as I killed the server. The only reason I spotted this was that my terminal emulator window was transparent. :D

Do you want to make a string out of them?

String s = new StringBuilder().append(char1).append(char2).append(char3).toString();

Note that

String b = "b";
String s = "a" + b + "c";

Actually compiles to

String s = new StringBuilder("a").append(b).append("c").toString();

Edit: as litb pointed out, you can also do this:

"" + char1 + char2 + char3;

That compiles to the following:

new StringBuilder().append("").append(c).append(c1).append(c2).toString();

Edit (2): Corrected string append comparison since, as cletus points out, a series of strings is handled by the compiler.

The purpose of the above is to illustrate what the compiler does, not to tell you what you should do.

<?php
// sample array
$fruits3 = [
    "iron",
    1,
    "ascorbic",
    "potassium",
    "ascorbic",
    2,
    "2",
    "1",
];

// Let's say we are looking for the item "ascorbic", in the above array

//a PHP function matching indexOf() from JS
echo(array_search("ascorbic", $fruits3, true)); //returns "2"

// a PHP function matching lastIndexOf() from JS world
function lastIndexOf($needle, $arr)
{
    return array_search($needle, array_reverse($arr, true), true);
}

echo(lastIndexOf("ascorbic", $fruits3)); //returns "4"

// so these (above) are the two ways to run a function similar to indexOf and lastIndexOf()

And to consume the hidden ID input back on your Edit action method:

[HttpPost]
public ActionResult Edit(FormCollection collection)
{
    ViewModel.ID = Convert.ToInt32(collection["ID"]);
}

Type:

type = list.AsEnumerable().SingleOrDefault().GetType();

It depends on nature of your data. The answer varies based on its size and data type. I saw a lot of SQL solutions based on ORDER BY. I would like to suggest javascript alternatives.

In all answers, I don't see anyone mentioning pagination problem for your future table. Let's make it easier for you. If your table doesn't have pagination, it's more likely that a javascript solution makes everything neat and clean for you on the client side. If you think this table will explode after you put data in it, you have to think about pagination as well. (you have to go to first page every time when you change the sorting column)

Another aspect is the data type. If you use SQL you have to be careful about the type of your data and what kind of sorting suites for it. For example, if in one of your VARCHAR columns you store integer numbers, the sorting will not take their integer value into account: instead of 1, 2, 11, 22 you will get 1, 11, 2, 22.

You can find jquery plugins or standalone javascript sortable tables on google. It worth mentioning that the <table> in HTML5 has sortable attribute, but apparently it's not implemented yet.

This is because a double[][] is an array of double[] which you can't assign 0.0 to (it would be like doing double[] vector = 0.0). In fact, Java has no true multidimensional arrays.

As it happens, 0.0 is the default value for doubles in Java, thus the matrix will actually already be filled with zeros when you get it from new. However, if you wanted to fill it with, say, 1.0 you could do the following:

I don't believe the API provides a method to solve this without using a loop. It's simple enough however to do it with a for-each loop.

double[][] matrix = new double[20][4];

// Fill each row with 1.0

I know this has been answered in another SOF post. However, you could do this if you know the hexadecimal.

textBox1.Background = (SolidColorBrush)new BrushConverter().ConvertFromString("#082049");

Use the map-function instead. It transforms the value inside the optional.

Like this:

private String getStringIfObjectIsPresent(Optional<Object> object) {
    return object.map(() -> {
        String result = "result";
        //some logic with result and return it
        return result;
    }).orElseThrow(MyCustomException::new);
}

First off: The variables a and b in the loops refer to numpy.ndarray objects.

In the first loop, a = a + 1 is evaluated as follows: the __add__(self, other) function of numpy.ndarray is called. This creates a new object and hence, A is not modified. Afterwards, the variable a is set to refer to the result.

In the second loop, no new object is created. The statement b += 1 calls the __iadd__(self, other) function of numpy.ndarray which modifies the ndarray object in place to which b is referring to. Hence, B is modified.

Here's another way of doing the code above using the openpyxl module that's compatible with xlsx. From what I've seen so far, it also keeps formatting.

from openpyxl import load_workbook
wb = load_workbook('names.xlsx')
ws = wb['SheetName']
ws['A1'] = 'A1'
wb.save('names.xlsx')

I have joined the answer from Lucas and "ASP.NET MVC Helpers, Merging two object htmlAttributes together" and plus controllerName to following code:

// Sample usage in CSHTML

 @Html.ActionImage("Edit",
       "EditController"
        new { id = MyId },
       "~/Content/Images/Image.bmp",
       new { width=108, height=129, alt="Edit" })

And the extension class for the code above:

using System.Collections.Generic;
using System.Reflection;
using System.Web.Mvc;

namespace MVC.Extensions
{
    public static class MvcHtmlStringExt
    {
        // Extension method
        public static MvcHtmlString ActionImage(
          this HtmlHelper html,
          string action,
          string controllerName,
          object routeValues,
          string imagePath,
          object htmlAttributes)
        {
            //https://stackoverflow.com/questions/4896439/action-image-mvc3-razor
            var url = new UrlHelper(html.ViewContext.RequestContext);

            // build the <img> tag
            var imgBuilder = new TagBuilder("img");
            imgBuilder.MergeAttribute("src", url.Content(imagePath));

            var dictAttributes = htmlAttributes.ToDictionary();

            if (dictAttributes != null)
            {
                foreach (var attribute in dictAttributes)
                {
                    imgBuilder.MergeAttribute(attribute.Key, attribute.Value.ToString(), true);
                }
            }                        

            string imgHtml = imgBuilder.ToString(TagRenderMode.SelfClosing);

            // build the <a> tag
            var anchorBuilder = new TagBuilder("a");
            anchorBuilder.MergeAttribute("href", url.Action(action, controllerName, routeValues));
            anchorBuilder.InnerHtml = imgHtml; // include the <img> tag inside            
            string anchorHtml = anchorBuilder.ToString(TagRenderMode.Normal);

            return MvcHtmlString.Create(anchorHtml);
        }

        public static IDictionary<string, object> ToDictionary(this object data)
        {
            //https://stackoverflow.com/questions/6038255/asp-net-mvc-helpers-merging-two-object-htmlattributes-together

            if (data == null) return null; // Or throw an ArgumentNullException if you want

            BindingFlags publicAttributes = BindingFlags.Public | BindingFlags.Instance;
            Dictionary<string, object> dictionary = new Dictionary<string, object>();

            foreach (PropertyInfo property in
                     data.GetType().GetProperties(publicAttributes))
            {
                if (property.CanRead)
                {
                    dictionary.Add(property.Name, property.GetValue(data, null));
                }
            }
            return dictionary;
        }
    }
}

newTitle is a local variable where you create the fields. So when that functions ends, the variable newTitle, does not exist anymore. (The JTextField that was referenced by newTitle does still exist however.)

Thus, increase the scope of the variable, so that you can access it another method.

public SomeFrame extends JFrame {
   JTextField myTitle;//can be used anywhere in this class

   creationOfTheFields()
   {
   //other code
      myTitle = new JTextField("spam");  
      myTitle.setBounds(80, 40, 225, 20);
      options.add(myTitle);
   //blabla other code
   }

   private void New_Name()  
   {  
      this.setTitle(myTitle.getText());  
   } 
}

Whatever advice path you go down, make a copy of your project folder, and rename the external most one to reflect what XCode version it is being opened in. Your choice on whether you want it to update syntax or not, but the main reason for all this bovver is your storyboard will be altered just by looking. It may be resolved by the time a new reader coming across this in the future, or

You never really specified how you wanted them disabled, or what would cause the disabling.

First, you want to figure out how to set the value to disabled, for that you would use JQuery's Attribute Functions, and have that function happen on an event, like a click, or the loading of the document.

If I understand correctly, you want to know how to convert bytes encoded as a hex string to its form as an ASCII text, like "537461636B" would be converted to "Stack", in such case then the following code should solve your problem.

Have not run any benchmarks but I assume it is not the peak of efficiency.

static char ByteToAscii(const char *input) {
  char singleChar, out;
  memcpy(&singleChar, input, 2);
  sprintf(&out, "%c", (int)strtol(&singleChar, NULL, 16));
  return out;
}

int HexStringToAscii(const char *input, unsigned int length,
                            char **output) {
  int mIndex, sIndex = 0;
  char buffer[length];
  for (mIndex = 0; mIndex < length; mIndex++) {
    sIndex = mIndex * 2;
    char b = ByteToAscii(&input[sIndex]);
    memcpy(&buffer[mIndex], &b, 1);
  }
  *output = strdup(buffer);
  return 0;
}

JDK Switch Script

I have adapted the answer from @Alex above and wrote the following to fix the code for Java 9.

$ cat ~/.jdk
#!/bin/bash

#list available jdks
alias jdks="/usr/libexec/java_home -V"
# jdk version switching - e.g. `jdk 6` will switch to version 1.6
function jdk() {
  echo "Switching java version $1";

  requestedVersion=$1
  oldStyleVersion=8
  # Set the version
  if [ $requestedVersion -gt $oldStyleVersion ]; then
    export JAVA_HOME=$(/usr/libexec/java_home -v $1);
  else
    export JAVA_HOME=`/usr/libexec/java_home -v 1.$1`;
  fi

  echo "Setting JAVA_HOME=$JAVA_HOME"

  which java
  java -version;
}

Switch to Java 8

$ jdk 8
Switching java version 8
Setting JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home
/usr/bin/java
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

Switch to Java 9

$ jdk 9
Switching java version 9
Setting JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/Contents/Home

WIth the Help of @excray's comment, I manage to figure it out the answer, What we need to do is actually write a simple for loop to iterate over the two arrays that represent the train data and test data.

First implement a simple lambda function to hold formula for the cosine calculation:

cosine_function = lambda a, b : round(np.inner(a, b)/(LA.norm(a)*LA.norm(b)), 3)

And then just write a simple for loop to iterate over the to vector, logic is for every "For each vector in trainVectorizerArray, you have to find the cosine similarity with the vector in testVectorizerArray."

from sklearn.feature_extraction.text import CountVectorizer
from sklearn.feature_extraction.text import TfidfTransformer
from nltk.corpus import stopwords
import numpy as np
import numpy.linalg as LA

train_set = ["The sky is blue.", "The sun is bright."] #Documents
test_set = ["The sun in the sky is bright."] #Query
stopWords = stopwords.words('english')

vectorizer = CountVectorizer(stop_words = stopWords)
#print vectorizer
transformer = TfidfTransformer()
#print transformer

trainVectorizerArray = vectorizer.fit_transform(train_set).toarray()
testVectorizerArray = vectorizer.transform(test_set).toarray()
print 'Fit Vectorizer to train set', trainVectorizerArray
print 'Transform Vectorizer to test set', testVectorizerArray
cx = lambda a, b : round(np.inner(a, b)/(LA.norm(a)*LA.norm(b)), 3)

for vector in trainVectorizerArray:
    print vector
    for testV in testVectorizerArray:
        print testV
        cosine = cx(vector, testV)
        print cosine

transformer.fit(trainVectorizerArray)
print
print transformer.transform(trainVectorizerArray).toarray()

transformer.fit(testVectorizerArray)
print 
tfidf = transformer.transform(testVectorizerArray)
print tfidf.todense()

Here is the output:

Fit Vectorizer to train set [[1 0 1 0]
 [0 1 0 1]]
Transform Vectorizer to test set [[0 1 1 1]]
[1 0 1 0]
[0 1 1 1]
0.408
[0 1 0 1]
[0 1 1 1]
0.816

[[ 0.70710678  0.          0.70710678  0.        ]
 [ 0.          0.70710678  0.          0.70710678]]

[[ 0.          0.57735027  0.57735027  0.57735027]]

#!/bin/sh

#Find the Process ID for syncapp running instance

PID=`ps -ef | grep syncapp 'awk {print $2}'`

if [[ -z "$PID" ]] then
--->    Kill -9 PID
fi

Not sure if this helps, but 'kill' is not spelled correctly. It's capitalized.

Try 'kill' instead.

Queue is an interface. You can't instantiate an interface directly except via an anonymous inner class. Typically this isn't what you want to do for a collection. Instead, choose an existing implementation. For example:

Queue<Integer> q = new LinkedList<Integer>();

or

Queue<Integer> q = new ArrayDeque<Integer>();

Typically you pick a collection implementation by the performance and concurrency characteristics you're interested in.

What Dweebo proposed works. But in my humble opinion it is unnecessary. A background drawable scales well by itself. The view should have fixed width and height, like in the following example:

 < RelativeLayout 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@android:color/black">

    <LinearLayout
        android:layout_width="500dip"
        android:layout_height="450dip"
        android:layout_centerInParent="true"
        android:background="@drawable/my_drawable"
        android:orientation="vertical"
        android:padding="30dip"
        >
        ...
     </LinearLayout>
 < / RelativeLayout>

add_header works as well with proxy_pass as without. I just today set up a configuration where I've used exactly that directive. I have to admit though that I've struggled as well setting this up without exactly recalling the reason, though.

Right now I have a working configuration and it contains the following (among others):

server {
    server_name  .myserver.com
    location / {
        proxy_pass  http://mybackend;
        add_header  X-Upstream  $upstream_addr;
    }
}

Before nginx 1.7.5 add_header worked only on successful responses, in contrast to the HttpHeadersMoreModule mentioned by Sebastian Goodman in his answer.

Since nginx 1.7.5 you can use the keyword always to include custom headers even in error responses. For example:

add_header X-Upstream $upstream_addr always;

Limitation: You cannot override the server header value using add_header.

Side note – if you want to use separate functions to set & clear interval, the interval variable have to be accessible for all of them, in 'relative global', or 'one level up' scope:

var interval = null;    

function startStuff(func, time) {
    interval = setInterval(func, time);
}

function stopStuff() {
    clearInterval(interval);
}

As mentioned in Greg's answer, mysqldump db_name | mysql new_db_name is the free, safe, and easy way to transfer data between databases. However, it's also really slow.

If you're looking to backup data, can't afford to lose data (in this or other databases), or are using tables other than innodb, then you should use mysqldump.

If you're looking for something for development, have all of your databases backed up elsewhere, and are comfortable purging and reinstalling mysql (possibly manually) when everything goes wrong, then I might just have the solution for you.

I couldn't find a good alternative, so I built a script to do it myself. I spent a lot of time getting this to work the first time and it honestly terrifies me a little to make changes to it now. Innodb databases were not meant to copied and pasted like this. Small changes cause this to fail in magnificent ways. I haven't had a problem since I finalized the code, but that doesn't mean you won't.

Systems tested on (but may still fail on):

• Ubuntu 16.04, default mysql, innodb, separate files per table
• Ubuntu 18.04, default mysql, innodb, separate files per table

What it does

1. Gets sudo privilege and verifies you have enough storage space to clone the database
2. Gets root mysql privileges
3. Creates a new database named after the current git branch
4. Clones structure to new database
5. Switches into recovery mode for innodb
6. Deletes default data in new database
7. Stops mysql
8. Clones data to new database
9. Starts mysql
10. Links imported data in new database
11. Switches out of recovery mode for innodb
12. Restarts mysql
13. Gives mysql user access to database
14. Cleans up temporary files

How it compares with mysqldump

On a 3gb database, using mysqldump and mysql would take 40-50 minutes on my machine. Using this method, the same process would only take ~8 minutes.

How we use it

We have our SQL changes saved alongside our code and the upgrade process is automated on both production and development, with each set of changes making a backup of the database to restore if there's errors. One problem we ran into was when we were working on a long term project with database changes, and had to switch branches in the middle of it to fix a bug or three.

In the past, we used a single database for all branches, and would have to rebuild the database whenever we switched to a branch that wasn't compatible with the new database changes. And when we switched back, we'd have to run the upgrades again.

We tried mysqldump to duplicate the database for different branches, but the wait time was too long (40-50 minutes), and we couldn't do anything else in the meantime.

This solution shortened the database clone time to 1/5 the time (think coffee and bathroom break instead of a long lunch).

Common tasks and their time

Switching between branches with incompatible database changes takes 50+ minutes on a single database, but no time at all after the initial setup time with mysqldump or this code. This code just happens to be ~5 times faster than mysqldump.

Here are some common tasks and roughly how long they would take with each method:

Create feature branch with database changes and merge immediately:

• Single database: ~5 minutes
• Clone with mysqldump: 50-60 minutes
• Clone with this code: ~18 minutes

Create feature branch with database changes, switch to master for a bugfix, make an edit on the feature branch, and merge:

• Single database: ~60 minutes
• Clone with mysqldump: 50-60 minutes
• Clone with this code: ~18 minutes

Create feature branch with database changes, switch to master for a bugfix 5 times while making edits on the feature branch inbetween, and merge:

• Single database: ~4 hours, 40 minutes
• Clone with mysqldump: 50-60 minutes
• Clone with this code: ~18 minutes

If everything goes smoothly, you should see something like:

You can try:

SELECT * 
FROM public."my_table"

Don't forget double quotes near my_table.

Just adding something that worked for me today, after much searching...

<div class="form-group" ng-class="{true: 'has-error'}[ctrl.submitted && myForm.myField.$error.required]">

Hope this assists in your successful development.

Undocumented Expression Syntax : Great Website Link... =)

I was just able to successfully trigger builds on commit using the Hooks option in Bitbucket to a Jenkins instance with the following steps (similar as link):

1. Generate a custom UUID or string sequence, save for later
2. Jenkins -> Configure Project -> Build Triggers -> "Trigger builds remotely (e.g., from scripts)"
3. (Paste UUID/string Here) for "Authentication Token"
4. Save
5. Edit Bitbucket repository settings
6. Hooks -> Edit: Endpoint: http://jenkins.something.co:9009/ Module Name: Project Name: Project Name Token: (Paste UUID/string Here)

The endpoint did not require inserting the basic HTTP auth in the URL despite using authentication, I did not use the Module Name field and the Project Name was entered case sensitive including a space in my test case. The build did not always trigger immediately but relatively fast. One other thing you may consider is disabling the "Prevent Cross Site Request Forgery exploits" option in "Configure Global Security" for testing as I've experienced all sorts of API difficulties from existing integrations when this option was enabled.

async actions help best when the actions does some I\O operations to DB or some network bound calls where the thread that processes the request will be stalled before it gets answer from the DB or network bound call which you just invoked. It's best you use await with them and it will really improve the responsiveness of your application (because less ASP input\output threads will be stalled while waiting for the DB or any other operation like that). In all my applications whenever many calls to DB very necessary I've always wrapped them in awaiatable method and called that with await keyword.

I usually read command output in to variables using the FOR command as it saves having to create temporary files. For example:

FOR /F "usebackq" %i IN (`hostname`) DO SET MYVAR=%i

Note, the above statement will work on the command line but not in a batch file. To use it in batch file escape the % in the FOR statement by putting them twice:

FOR /F "usebackq" %%i IN (`hostname`) DO SET MYVAR=%%i
ECHO %MYVAR%

There's a lot more you can do with FOR. For more details just type HELP FOR at command prompt.

In my IBM AIX Server (OS version: AIX 5.2), use:

find ./ -type f -print -exec grep -n -i "stringYouWannaFind" {} \; 

this will print out path/file name and relative line number in the file like:

./inc/xxxx_x.h

2865: /** Description : stringYouWannaFind */

anyway,it works for me : )

You should do mkdir build and cd build while inside opencv folder, not the opencv-contrib folder. The CMakeLists.txt is there.

When working with fragments, instead of using this or refering to the context, always use getActivity(). You should call

getActivity().finish();

to finish your activity from fragment.

An alternative solution inspired by the accepted response, but that uses an inverted logic:

MODE="${1}"

echo "<${MODE}>"
[[ "${MODE}" =~ ^(preview|live|both)$ ]] && echo "OK" || echo "Uh?"

Here, the input ($MODE) must be one of the options in the regular expression ('preview', 'live', or 'both'), contrary to matching the whole options list to the user input. Of course, you do not expect the regular expression to change.

To read a file...

set /P Variable=<File.txt

To Write a file

@echo %DataToWrite%>File.txt

note; having spaces before the <> character causes a space to be added at the end of the variable, also

To add to a file,like a logger program, First make a file with a single enter key in it called e.txt

set /P Data=<log0.log
set /P Ekey=<e.txt
@echo %Data%%Ekey%%NewData%>log0.txt

your log will look like this

Entry1
Entry2 

and so on

Anyways a couple useful things

you can use zscore to analyze the data in column C and D for outliers, where zscore is the series - series.mean / series.std(). Use apply too create a user defined function for difference between C and D creating a new resulting dataframe. Apply uses the group result set.

from scipy.stats import zscore

columns = ['A', 'B', 'C', 'D']
records = [
['foo', 'one', 0.162003, 0.087469],
['bar', 'one', -1.156319, -1.5262719999999999],
['foo', 'two', 0.833892, -1.666304],     
['bar', 'three', -2.026673, -0.32205700000000004],
['foo', 'two', 0.41145200000000004, -0.9543709999999999],
['bar', 'two', 0.765878, -0.095968],
['foo', 'one', -0.65489, 0.678091],
['foo', 'three', -1.789842, -1.130922]
]
df = pd.DataFrame.from_records(records, columns=columns)
print(df)

standardize=df.groupby('A')['C','D'].transform(zscore)
print(standardize)
outliersC= (standardize['C'] <-1.1) | (standardize['C']>1.1)
outliersD= (standardize['D'] <-1.1) | (standardize['D']>1.1)

results=df[outliersC | outliersD]
print(results)
