here's an updated fiddle where the user's input is saved in local storage automatically. each time the fiddle is re-run or the page is refreshed the previous state is restored. this way you do not need to prompt users to save, it just saves on it's own.

http://jsfiddle.net/tZPg4/9397/

stack overflow requires I include some code with a jsFiddle link so please ignore snippet:

localStorage.setItem(...)

In .htaccess file at site root directory edit following line:

<ifmodule mod_security.c>_x000D_
_x000D_
SecFilterEngine Off_x000D_
SecFilterScanPOST Off_x000D_
_x000D_
</ifmodule>_x000D_
_x000D_
<IfModule mod_rewrite.c>_x000D_
RewriteEngine On_x000D_
RewriteBase /_x000D_
RewriteCond %{REQUEST_FILENAME} !-f_x000D_
RewriteCond %{REQUEST_FILENAME} !-d_x000D_
RewriteRule . /index.php [L]_x000D_
</IfModule>

Just keep the mod_security rules like SecFilterEngine and parts apart from each other. Its works for apache server

This is my sample code for load static variable

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class OnelinkConfig {
    public static int MODULE_CODE;
    public static int DEFAULT_PAGE;
    public static int DEFAULT_SIZE;

    @Autowired
    public void loadOnelinkConfig(@Value("${onelink.config.exception.module.code}") int code,
            @Value("${onelink.config.default.page}") int page, @Value("${onelink.config.default.size}") int size) {
        MODULE_CODE = code;
        DEFAULT_PAGE = page;
        DEFAULT_SIZE = size;
    }
}

Here's my solution (there's no need to deactivate instant run) Do all these steps in the stated order:

1- Gradle Build (root level)

gradle

2 - Gradle build + clean (app level)

gradle app

3 - Choose app on the top bar (left of Run 'app')

4 - Clean Project:

Navigate to Build > Clean Project

And it should work now! You shouldn't disable instant run if you follow these steps

If you're concatenating more than two arrays, concat() is the way to go for convenience and likely performance.

var a = [1, 2], b = ["x", "y"], c = [true, false];
var d = a.concat(b, c);
console.log(d); // [1, 2, "x", "y", true, false];

For concatenating just two arrays, the fact that push accepts multiple arguments consisting of elements to add to the array can be used instead to add elements from one array to the end of another without producing a new array. With slice() it can also be used instead of concat() but there appears to be no performance advantage from doing this.

var a = [1, 2], b = ["x", "y"];
a.push.apply(a, b);
console.log(a); // [1, 2, "x", "y"];

In ECMAScript 2015 and later, this can be reduced even further to

a.push(...b)

However, it seems that for large arrays (of the order of 100,000 members or more), the technique passing an array of elements to push (either using apply() or the ECMAScript 2015 spread operator) can fail. For such arrays, using a loop is a better approach. See https://stackoverflow.com/a/17368101/96100 for details.

%w(foo bar) is a shortcut for ["foo", "bar"]. Meaning it's a notation to write an array of strings separated by spaces instead of commas and without quotes around them. You can find a list of ways of writing literals in zenspider's quickref.

This is python code for the ping in range of the 192.168.0.0-192.168.0.100. You can change for loop as you comfort.

# -*- coding: utf-8 -*-
import socket
import os
import sys

up_ip =[] #list to store the ip-addresses of server online
for x in range(100):  #here range is 0-100. You can change the range according to your comfort

    server_ip = '192.168.0.'+ str(x)
    print "Trying ,server_ip,... \n"

    rep = os.system('ping -c 1 ' + server_ip)

    if rep == 0:
        up_ip.append(server_ip)
        print '******************* Server Is Up **************** \n'
    else:
        print 'server is down \n'

print up_ip

One way to automatically do this is the bbox_inches='tight' kwarg to plt.savefig.

E.g.

import matplotlib.pyplot as plt
import numpy as np
data = np.arange(3000).reshape((100,30))
plt.imshow(data)
plt.savefig('test.png', bbox_inches='tight')

Another way is to use fig.tight_layout()

import matplotlib.pyplot as plt
import numpy as np

xs = np.linspace(0, 1, 20); ys = np.sin(xs)

fig = plt.figure()
axes = fig.add_subplot(1,1,1)
axes.plot(xs, ys)

# This should be called after all axes have been added
fig.tight_layout()
fig.savefig('test.png')

Queue is an interface in java, you can not do that.

Instead you have two options:

option1:

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

option2:

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

I recommend using option2 as it is bit faster than the other

You can't. They simply do not work that way. A drop down menu must have one of its options selected at all times.

You could (although I don't recommend it) watch for a change event and then use JS to delete the first option if it is blank.

You need a SQL profiler, which actually runs outside SQL Management Studio. If you have a paid version of SQL Server (like the developer edition), it should be included in that as another utility.

If you're using a free edition (SQL Express), they have freeware profiles that you can download. I've used AnjLab's profiler (available at http://sites.google.com/site/sqlprofiler), and it seemed to work well.

You can do it programmatically:

ddlColor.DataSource = from p in db.ProductTypes
                                  where p.ProductID == pID
                                  orderby p.Color 
                                  select new { p.Color };
ddlColor.DataTextField = "Color";
ddlColor.DataBind();
ddlColor.Items.Insert(0, new ListItem("Select", "NA"));

Or add it in markup as:

<asp:DropDownList .. AppendDataBoundItems="true">
   <Items>
       <asp:ListItem Text="Select" Value="" />
   </Items>
</asp:DropDownList>

This will also checks in leap year. This is pure regex, so it's faster than any lib (also faster than moment.js). But if you gonna use a lot of dates in ur code, I do recommend to use moment.js

var dateRegex = /^(?=\d)(?:(?:31(?!.(?:0?[2469]|11))|(?:30|29)(?!.0?2)|29(?=.0?2.(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00)))(?:\x20|$))|(?:2[0-8]|1\d|0?[1-9]))([-.\/])(?:1[012]|0?[1-9])\1(?:1[6-9]|[2-9]\d)?\d\d(?:(?=\x20\d)\x20|$))?(((0?[1-9]|1[012])(:[0-5]\d){0,2}(\x20[AP]M))|([01]\d|2[0-3])(:[0-5]\d){1,2})?$/;

console.log(dateRegex.test('21/01/1986'));

Dependent on how the API is created, normally with a 201 (created) you would return the resource which was created. For example if it was creating a user account you would do something like:

return {"data": {"username": "test","id":"fdsf345"}}, 201

Note the postfixed number is the status code returned.

Alternatively, you may want to send a message to the client such as:

return {"msg": "Created Successfully"}, 201

Put Route Prefix [RoutePrefix("api/Profiles")] at the controller level and put a route at action method [Route("LikeProfile")]. Don't need to change anything in global.asax file

namespace KhandalVipra.Controllers
{
    [RoutePrefix("api/Profiles")]
    public class ProfilesController : ApiController
    {
        // POST: api/Profiles/LikeProfile
        [Authorize]
        [HttpPost]
        [Route("LikeProfile")]
        [ResponseType(typeof(List<Like>))]
        public async Task<IHttpActionResult> LikeProfile()
        {
        }
    }
}

I got a similar error and hit this page while searching the solution.

With Qt this error can happen if you forget to add the QT_WRAP_CPP( ... ) step in your build to run meta object compiler (moc). Including the Qt header is not sufficient.

You use something like

from flask import send_file

@app.route('/get_image')
def get_image():
    if request.args.get('type') == '1':
       filename = 'ok.gif'
    else:
       filename = 'error.gif'
    return send_file(filename, mimetype='image/gif')

to send back ok.gif or error.gif, depending on the type query parameter. See the documentation for the send_file function and the request object for more information.

Yes You can either set [disabled]= "true" or if it is an radio button or checkbox then you can simply use disable

For radio button:

<md-radio-button disabled>Select color</md-radio-button>

For dropdown:

<ng-select (selected)="someFunction($event)" [disabled]="true"></ng-select>

None of the above responses are working for error that has no body but still has some describing text. For me, it was SSL certificate problem: unable to get local issuer certificate error. So I looked right into the code, because doc does't really say much, and did this (in Guzzle 7.1):

try {
    // call here
} catch (\GuzzleHttp\Exception\RequestException $e) {
    if ($e->hasResponse()) {
        $response = $e->getResponse();
        // message is in $response->getReasonPhrase()
    } else {
        $response = $e->getHandlerContext();
        if (isset($response['error'])) {
            // message is in $response['error']
        } else {
            // Unknown error occured!
        }
    }
}

You're looking for the SyndicationFeed class, which does exactly that.

I recently stumbled up on the same problem. Here is the synopsis of my solution:

Basic constituent code blocks needed

The following are the required basic code blocks of your client application

1. Session request section: request a session with the provider
2. Session authentication section: provide credentials to the provider
3. Client section: create the Client
4. Security Header section: add the WS-Security Header to the Client
5. Consumption section: consume available operations (or methods) as needed

What modules do you need?

Many suggested to use Python modules such as urllib2 ; however, none of the modules work-at least for this particular project.

So, here is the list of the modules you need to get. First of all, you need to download and install the latest version of suds from the following link:

pypi.python.org/pypi/suds-jurko/0.4.1.jurko.2

Additionally, you need to download and install requests and suds_requests modules from the following links respectively ( disclaimer: I am new to post in here, so I can't post more than one link for now).

pypi.python.org/pypi/requests

pypi.python.org/pypi/suds_requests/0.1

Once you successfully download and install these modules, you are good to go.

The code

Following the steps outlined earlier, the code looks like the following: Imports:

import logging
from suds.client import Client
from suds.wsse import *
from datetime import timedelta,date,datetime,tzinfo
import requests
from requests.auth import HTTPBasicAuth
import suds_requests

Session request and authentication:

username=input('Username:')
password=input('password:')
session = requests.session()
session.auth=(username, password)

Create the Client:

client = Client(WSDL_URL, faults=False, cachingpolicy=1, location=WSDL_URL, transport=suds_requests.RequestsTransport(session))

Add WS-Security Header:

...
addSecurityHeader(client,username,password)
....

def addSecurityHeader(client,username,password):
    security=Security()
    userNameToken=UsernameToken(username,password)
    timeStampToken=Timestamp(validity=600)
    security.tokens.append(userNameToken)
    security.tokens.append(timeStampToken)
    client.set_options(wsse=security)

Please note that this method creates the security header depicted in Fig.1. So, your implementation may vary depending on the correct security header format provided by the owner of the service you are consuming.

Consume the relevant method (or operation) :

result=client.service.methodName(Inputs)

Logging:

One of the best practices in such implementations as this one is logging to see how the communication is executed. In case there is some issue, it makes debugging easy. The following code does basic logging. However, you can log many aspects of the communication in addition to the ones depicted in the code.

logging.basicConfig(level=logging.INFO) 
logging.getLogger('suds.client').setLevel(logging.DEBUG) 
logging.getLogger('suds.transport').setLevel(logging.DEBUG)

Result:

Here is the result in my case. Note that the server returned HTTP 200. This is the standard success code for HTTP request-response.

(200, (collectionNodeLmp){
   timestamp = 2014-12-03 00:00:00-05:00
   nodeLmp[] = 
      (nodeLmp){
         pnodeId = 35010357
         name = "YADKIN"
         mccValue = -0.19
         mlcValue = -0.13
         price = 36.46
         type = "500 KV"
         timestamp = 2014-12-03 01:00:00-05:00
         errorCodeId = 0
      },
      (nodeLmp){
         pnodeId = 33138769
         name = "ZION 1"
         mccValue = -0.18
         mlcValue = -1.86
         price = 34.75
         type = "Aggregate"
         timestamp = 2014-12-03 01:00:00-05:00
         errorCodeId = 0
      },
 })

I know this is an old question, but maybe I can be of help to someone, bc this also stumped me until I read the documentation a bit more:

prevArrow string (html|jQuery selector) | object (DOM node|jQuery object) Previous Allows you to select a node or customize the HTML for the "Previous" arrow.

nextArrow string (html|jQuery selector) | object (DOM node|jQuery object) Next Allows you to select a node or customize the HTML for the "Next" arrow.

this is how i changed my buttons.. worked perfectly.

  $('.carousel-content').slick({
      prevArrow:"<img class='a-left control-c prev slick-prev' src='../images/shoe_story/arrow-left.png'>",
      nextArrow:"<img class='a-right control-c next slick-next' src='../images/shoe_story/arrow-right.png'>"
  });

Use this

select * from (
 SELECT ARIDNR,LIEFNR,row_number() over 
     (partition by ARIDNR order by ARIDNR) as RowNum) a
where a.RowNum >1

Use a list instead and replace your foreach loop with a for loop:

@model IList<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()

    @for (var i = 0; i < Model.Count; i++) 
    {
        <tr>
            <td>
                @Html.HiddenFor(x => x[i].IP)           
                @Html.CheckBoxFor(x => x[i].Checked)
            </td>
            <td>
                @Html.DisplayFor(x => x[i].IP)
            </td>
        </tr>
    }
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

Alternatively you could use an editor template:

@model IEnumerable<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()
    @Html.EditorForModel()   
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

and then define the template ~/Views/Shared/EditorTemplates/BlockedIPViewModel.cshtml which will automatically be rendered for each element of the collection:

@model BlockedIPViewModel
<tr>
    <td>
        @Html.HiddenFor(x => x.IP)
        @Html.CheckBoxFor(x => x.Checked)
    </td>
    <td>
        @Html.DisplayFor(x => x.IP)
    </td>
</tr>

The reason you were getting null in your controller is because you didn't respect the naming convention for your input fields that the default model binder expects to successfully bind to a list. I invite you to read the following article.

Once you have read it, look at the generated HTML (and more specifically the names of the input fields) with my example and yours. Then compare and you will understand why yours doesn't work.

If you set the date to

DateTime dNewDate = new DateTime();

The value is set to {1/1/0001 12:00:00 AM}

You can check this just use table inside table like this

<!DOCTYPE html>
<html>

<head>
  <style>
    table,
    th,
    td {
      border: 1px solid black;
      border-collapse: collapse;
    }
  </style>
</head>

<body>
  <table style="width:100%">
    <tr>
      <th>ABC</th>
      <th>ABC</th>
      <th>ABC</th>
      <th>ABC</th>
    </tr>
    <tr>
      <td>Item1</td>
      <td>Item1</td>
      <td>
        <table style="width:100%">
          <tr>
            <td>name1</td>
            <td>price1</td>
          </tr>
          <tr>
            <td>name2</td>
            <td>price2</td>
          </tr>
          <tr>
            <td>name3</td>
            <td>price3</td>
          </tr>
        </table>
      </td>
      <td>item1</td>
    </tr>
    <tr>
      <td>A</td>
      <td>B</td>
      <td>C</td>
      <td>D</td>

    <tr>

I had the issue when I put jcenter() before google() in project level build.gradle. When I changed the order and put google() before jcenter() in build.gradle the problem disappeared

Here is my final build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

The clean way to use mbstowcs is to call it twice to find the length of the result:

  const char * cs = <your input char*>
  size_t wn = mbsrtowcs(NULL, &cs, 0, NULL);

  // error if wn == size_t(-1)

  wchar_t * buf = new wchar_t[wn + 1]();  // value-initialize to 0 (see below)

  wn = mbsrtowcs(buf, &cs, wn + 1, NULL);

  // error if wn == size_t(-1)

  assert(cs == NULL); // successful conversion

  // result now in buf, return e.g. as std::wstring

  delete[] buf;

Don't forget to call setlocale(LC_CTYPE, ""); at the beginning of your program!

The advantage over the Windows MultiByteToWideChar is that this is entirely standard C, although on Windows you might prefer the Windows API function anyway.

I usually wrap this method, along with the opposite one, in two conversion functions string->wstring and wstring->string. If you also add trivial overloads string->string and wstring->wstring, you can easily write code that compiles with the Winapi TCHAR typedef in any setting.

[Edit:] I added zero-initialization to buf, in case you plan to use the C array directly. I would usually return the result as std::wstring(buf, wn), though, but do beware if you plan on using C-style null-terminated arrays.[/]

In a multithreaded environment you should pass a thread-local conversion state to the function as its final (currently invisible) parameter.

Here is a small rant of mine on this topic.

Below is a simple command, where a dev or a git user can pass a deleted file name from the repository root directory and get the history:

git log --diff-filter=D --summary | grep filename | awk '{print $4; exit}' | xargs git log --all -- 

If anybody, can improve the command, please do.

If file really exists and you want to replace it use below code:

string file = "c:\test\SomeFile.txt"
string moveTo = "c:\test\test\SomeFile.txt"

if (File.Exists(moveTo))
{
    File.Delete(moveTo);
}

File.Move(file, moveTo);

In my case, I needed to allow many inactives and only one combination of two keys active, like this:

UUL_USR_IDF  UUL_UND_IDF    UUL_ATUAL
137          18             0
137          19             0
137          20             1
137          21             0

This seems to work:

CREATE UNIQUE NONCLUSTERED INDEX UQ_USR_UND_UUL_USR_IDF_UUL_ATUAL
ON USER_UND(UUL_USR_IDF, UUL_ATUAL)
WHERE UUL_ATUAL = 1;

Here are my test cases:

SELECT * FROM USER_UND WHERE UUL_USR_IDF = 137

insert into USER_UND values (137, 22, 1) --I CAN NOT => Cannot insert duplicate key row in object 'dbo.USER_UND' with unique index 'UQ_USR_UND_UUL_USR_IDF_UUL_ATUAL'. The duplicate key value is (137, 1).
insert into USER_UND values (137, 23, 0) --I CAN
insert into USER_UND values (137, 24, 0) --I CAN

DELETE FROM USER_UND WHERE UUL_USR_ID = 137

insert into USER_UND values (137, 22, 1) --I CAN
insert into USER_UND values (137, 27, 1) --I CAN NOT => Cannot insert duplicate key row in object 'dbo.USER_UND' with unique index 'UQ_USR_UND_UUL_USR_IDF_UUL_ATUAL'. The duplicate key value is (137, 1).
insert into USER_UND values (137, 28, 0) --I CAN
insert into USER_UND values (137, 29, 0) --I CAN

Piggy backing on @MikkaS answer for Mongo Client v3.x, I just needed the async / await format, which looks slightly modified as this:

const myFunc = async () => {

     // Prepping here...


    // Connect
    let client = await MongoClient.connect('mongodb://localhost');
    let db = await client.db();

    // Run the query
    let cursor = await db.collection('customers').find({});

    // Do whatever you want on the result.
}

I had a similar issue. It is caused due the dependent package 'rJava'. This problem can be overcome by re-directing the R to use a different JAVA_HOME.

if(Sys.getenv("JAVA_HOME")!=""){
    Sys.setenv(JAVA_HOME="")
}
library(rJava)

This worked for me.

Example: In a simple terms if you have a web service of calculator.

WSDL: WSDL tells about the functions that you can implement or exposed to the client. For example: add, delete, subtract and so on.

SOAP: Where as using SOAP you actually perform actions like doDelete(), doSubtract(), doAdd(). So SOAP and WSDL are apples and oranges. We should not compare them. They both have their own different functionality.

Why we use SOAP and WSDL: For platform independent data exchange.

EDIT: In a normal day to day life example:

WSDL: When we go to a restaurant we see the Menu Items, those are the WSDL's.

Proxy Classes: Now after seeing the Menu Items we make up our Mind (Process our mind on what to order): So, basically we make Proxy classes based on WSDL Document.

SOAP: Then when we actually order the food based on the Menu's: Meaning we use proxy classes to call upon the service methods which is done using SOAP. :)

I used UIKeyInput's built in feature hasText: docs

For Swift 2.3 I had to use it as a method instead of a property (as it is referenced in the docs):

if textField1.hasText() && textField2.hasText() {
    // both textfields have some text
}

Using the BaseName in Get-ChildItem displays the name of the file and and using Name displays the file name with the extension.

$filepath = Get-ChildItem "E:\Test\Basic-English-Grammar-1.pdf"

$filepath.BaseName

Basic-English-Grammar-1

$filepath.Name

Basic-English-Grammar-1.pdf

you should just be able to call it by typing in the file name. You may have to call ./a.exe as the current directory is usually not on the path for security reasons.

Run the npm update after installing all peer dependencies and it will work.

In case someone is using Laravel and is getting this problem. I was getting this as well and the issue was in the order in which I was inserting the ids (i.e., the foreign keys) in the pivot table.

To be concrete, find below an example for a many to many relationship:

wordtokens <-> wordtoken_wordchunk <-> wordchunks

// wordtoken_wordchunk table
Schema::create('wordtoken_wordchunk', function(Blueprint $table) {
        $table->integer('wordtoken_id')->unsigned();
        $table->integer('wordchunk_id')->unsigned();

        $table->foreign('wordtoken_id')->references('id')->on('word_tokens')->onDelete('cascade');
        $table->foreign('wordchunk_id')->references('id')->on('wordchunks')->onDelete('cascade');

        $table->primary(['wordtoken_id', 'wordchunk_id']);
    });

// wordchunks table
Schema::create('wordchunks', function (Blueprint $table) {
        $table->increments('id');
        $table->timestamps();
        $table->string('text');
    });

// wordtokens table
Schema::create('word_tokens', function (Blueprint $table) {
        $table->increments('id');
        $table->string('text');
});

Now my models look like follows:

class WordToken extends Model
{
   public function wordchunks() {
      return $this->belongsToMany('App\Wordchunk');
   }
}

class Wordchunk extends Model
{

    public function wordTokens() {
        return $this->belongsToMany('App\WordToken', 'wordtoken_wordchunk', 'wordchunk_id', 'wordtoken_id');
    }
}

I fixed the problem by exchanging the order of 'wordchunk_id' and 'wordtoken_id' in the Wordchunk model.

For code completion, this is how I persist the models:

private function persistChunks($chunks) {
    foreach ($chunks as $chunk) {
        $model = new Wordchunk();
        $model->text = implode(' ', array_map(function($token) {return $token->text;}, $chunk));
        $tokenIds = array_map(function($token) {return $token->id;}, $chunk);
        $model->save();
        $model->wordTokens()->attach($tokenIds);
    }
}

You can use Node.js for Mobile Apps.

It works on Android devices and simulators, with pre-built binaries for armeabi-v7a, x86, arm64-v8a, x86_64. It also works on iOS, though that's outside the scope of this question.

Like JXcore, it is used to host a Node.js engine in the same process as the app, in a dedicated thread. Unlike JXcore, it is basically pure Node.js, built as a library, with a few portability fixes to run on Android. This means that it's much easier to keep the project up to date with mainline Node.js.

Plugins for Cordova and React Native are also available. The plugins provide a communication layer between the JavaScript side of those frameworks and the Node.js side. They also simplify development by taking care of a few things automatically, like packaging modules and cross-compiling native modules at build time.

Full disclosure: I work for the company that develops Node.js for Mobile Apps.

In Asp.Net MVC when you use @Html.AntiForgeryToken() Razor creates a hidden input field with name __RequestVerificationToken to store tokens. If you want to write an AJAX implementation you have to fetch this token yourself and pass it as a parameter to the server so it can be validated.

Step 1: Get the token

var token = $('input[name="`__RequestVerificationToken`"]').val();

Step 2: Pass the token in the AJAX call

function registerStudent() {

var student = {     
    "FirstName": $('#fName').val(),
    "LastName": $('#lName').val(),
    "Email": $('#email').val(),
    "Phone": $('#phone').val(),
};

$.ajax({
    url: '/Student/RegisterStudent',
    type: 'POST',
    data: { 
     __RequestVerificationToken:token,
     student: student,
        },
    dataType: 'JSON',
    contentType:'application/x-www-form-urlencoded; charset=utf-8',
    success: function (response) {
        if (response.result == "Success") {
            alert('Student Registered Succesfully!')

        }
    },
    error: function (x,h,r) {
        alert('Something went wrong')
      }
})
};

Note: The content type should be 'application/x-www-form-urlencoded; charset=utf-8'

I have uploaded the project on Github; you can download and try it.

https://github.com/lambda2016/AjaxValidateAntiForgeryToken

You can also use breakpoints. Assuming the value you want is defined within the scope of your breakpoint you have 3 options:

print it in console doing:

po some_paramter

Bare in mind in objective-c for properties you can't use self.

po _someProperty
po self.someProperty // would not work

po stands for print object.

Or can just use Xcode 'Variable Views' . See the image

I highly recommend seeing Debugging with Xcode from Apple

Or just hover over within your code. Like the image below.

Simple

var a=[{a:4}], b=[{b:5}]

angular.merge(a,b) // [{a:4, b:5}]

Tested on angular 1.4.1

You can use izip to combine your lists, and then iterate them

for val in itertools.izip(l1,l2,l3,l4,l5):
    writer.writerow(val)

Yes, try wrapping it with <pre>, e.g.:

echo '<pre>' , var_dump($variable) , '</pre>';

Sometimes, I try to use anonymous function to achieve defining and assigning happen at the same line. like below:

a, b = 4, 8

c := func() int {
    if a >b {
      return a
    } 
    return b
  } ()

https://play.golang.org/p/rMjqytMYeQ0

This is my summary of the above and works perfectly for me. Thanks for the info!

<script language='javascript' type='text/javascript'>
    $(document).ready(function () {
        var firstInput = $('form').find('input[type=text],input[type=password],input[type=radio],input[type=checkbox],textarea,select').filter(':visible:first');
        if (firstInput != null) {
            firstInput.focus();
        }
    });
</script>

Select date1 - (date2 - 1) * 24 * 60 *60 * 1000 from Table;

As for me resetConfig only works

this.router.resetConfig(newRoutes);

Or concat with previous

this.router.resetConfig([...newRoutes, ...this.router.config]);

But keep in mind that the last must be always route with path **

CASE isn't used for flow control... for this, you would need to use IF...

But, there's a set-based solution to this problem instead of the procedural approach:

UPDATE tblEmployee
SET 
  InOffice = CASE WHEN @NewStatus = 'InOffice' THEN -1 ELSE InOffice END,
  OutOffice = CASE WHEN @NewStatus = 'OutOffice' THEN -1 ELSE OutOffice END,
  Home = CASE WHEN @NewStatus = 'Home' THEN -1 ELSE Home END
WHERE EmpID = @EmpID

Note that the ELSE will preserves the original value if the @NewStatus condition isn't met.

When you say pair[0], that gives you ("a", 1). The thing in parentheses is a tuple, which, like a list, is a type of collection. So you can access the first element of that thing by specifying [0] or [1] after its name. So all you have to do to get the first element of the first element of pair is say pair[0][0]. Or if you want the second element of the third element, it's pair[2][1].

1. As it is, your compiled application contains the key strings, but also the constant names APP_KEY and APP_SECRET. Extracting keys from such self-documenting code is trivial, for instance with the standard Android tool dx.

2. You can apply ProGuard. It will leave the key strings untouched, but it will remove the constant names. It will also rename classes and methods with short, meaningless names, where ever possible. Extracting the keys then takes some more time, for figuring out which string serves which purpose.

   Note that setting up ProGuard shouldn't be as difficult as you fear. To begin with, you only need to enable ProGuard, as documented in project.properties. If there are any problems with third-party libraries, you may need to suppress some warnings and/or prevent them from being obfuscated, in proguard-project.txt. For instance:

   -dontwarn com.dropbox.**
   -keep class com.dropbox.** { *; }
   

   This is a brute-force approach; you can refine such configuration once the processed application works.

3. You can obfuscate the strings manually in your code, for instance with a Base64 encoding or preferably with something more complicated; maybe even native code. A hacker will then have to statically reverse-engineer your encoding or dynamically intercept the decoding in the proper place.

4. You can apply a commercial obfuscator, like ProGuard's specialized sibling DexGuard. It can additionally encrypt/obfuscate the strings and classes for you. Extracting the keys then takes even more time and expertise.

5. You might be able to run parts of your application on your own server. If you can keep the keys there, they are safe.

In the end, it's an economic trade-off that you have to make: how important are the keys, how much time or software can you afford, how sophisticated are the hackers who are interested in the keys, how much time will they want to spend, how much worth is a delay before the keys are hacked, on what scale will any successful hackers distribute the keys, etc. Small pieces of information like keys are more difficult to protect than entire applications. Intrinsically, nothing on the client-side is unbreakable, but you can certainly raise the bar.

(I am the developer of ProGuard and DexGuard)

With an Android-powered device, you can develop and debug your Android applications just as you would on the emulator.

1. Declare your application as "debuggable" in AndroidManifest.xml.

<application
    android:debuggable="true"
    ... >
    ...
</application>

2. On your handset, navigate to Settings > Security and check Unknown sources

3. Go to Settings > Developer Options and check USB debugging
Note that if Developer Options is invisible you will need to navigate to Settings > About Phone and tap on Build number several times until you are notified that it has been unlocked.

4. Set up your system to detect your device.
Follow the instructions below for your OS:

Windows Users

Install the Google USB Driver from the ADT SDK Manager
(Support for: ADP1, ADP2, Verizon Droid, Nexus One, Nexus S).

For devices not listed above, install an OEM driver for your device

Mac OS X

Your device should automatically work; Go to the next step

Ubuntu Linux

Add a udev rules file that contains a USB configuration for each type of device you want to use for development. In the rules file, each device manufacturer is identified by a unique vendor ID, as specified by the ATTR{idVendor} property. For a list of vendor IDs, click here. To set up device detection on Ubuntu Linux:

1. Log in as root and create this file: /etc/udev/rules.d/51-android.rules.
2. Use this format to add each vendor to the file:
   SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"
   In this example, the vendor ID is for HTC. The MODE assignment specifies read/write permissions, and GROUP defines which Unix group owns the device node.
3. Now execute: chmod a+r /etc/udev/rules.d/51-android.rules

Note: The rule syntax may vary slightly depending on your environment. Consult the udev documentation for your system as needed. For an overview of rule syntax, see this guide to writing udev rules.

5. Run the project with your connected device.

With Eclipse/ADT: run or debug your application as usual. You will be presented with a Device Chooser dialog that lists the available emulator(s) and connected device(s).

With ADB: issue commands with the -d flag to target your connected device.

$crud->set_relation('id','students','{first_name} {last_name}');
$crud->display_as('student_id','Students Name');

In past projects I worked on, the endpoint was a relative property. That is to say it may or may not have been appended to, but it always contained the protocol://host:port/partOfThePath.

If the service being called had a dynamic part to it, for example a ?param=dynamicValue, then that part would get added to the endpoint. But many times the endpoint could be used as is without having to be amended.

Whats important to understand is what an endpoint is not and how it helps. For example an alternative way to pass the information stored in an endpoint would be to store the different parts of the endpoint in separate properties. For example:

hostForServiceA=someIp
portForServiceA=8080
pathForServiceA=/some/service/path
hostForServiceB=someIp
portForServiceB=8080
pathForServiceB=/some/service/path

Or if the same host and port across multiple services:

host=someIp
port=8080
pathForServiceA=/some/service/path
pathForServiceB=/some/service/path

In those cases the full URL would need to be constructed in your code as such:

String url = "http://" + host + ":" + port + pathForServiceA  + "?" + dynamicParam + "=" + dynamicValue;

In contract this can be stored as an endpoint as such

serviceAEndpoint=http://host:port/some/service/path?dynamicParam=

And yes many times we stored the endpoint up to and including the '='. This lead to code like this:

String url = serviceAEndpoint + dynamicValue;

Hope that sheds some light.

The Java 8 streaming api offers an elegant alternative:

public static void main(String[] args) {
    double avg = Arrays.stream(new int[]{1,3,2,5,8}).average().getAsDouble();

    System.out.println("avg: " + avg);
}

Use try_files and named location block ('@apachesite'). This will remove unnecessary regex match and if block. More efficient.

location / {
    root /path/to/root/of/static/files;
    try_files $uri $uri/ @apachesite;

    expires max;
    access_log off;
}

location @apachesite {
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
}

Update: The assumption of this config is that there doesn't exist any php script under /path/to/root/of/static/files. This is common in most modern php frameworks. In case your legacy php projects have both php scripts and static files mixed in the same folder, you may have to whitelist all of the file types you want nginx to serve.

Disabling Lint warnings will easily get you into trouble later on. You're better off just specifying contentDescription for all of your ImageViews. If you don't need a description, then just use:

android:contentDescription="@null"

@QueryMap worked for me instead of FieldMap

If you have a bunch of GET params, another way to pass them into your url is a HashMap.

class YourActivity extends Activity {

private static final String BASEPATH = "http://www.example.com";

private interface API {
    @GET("/thing")
    void getMyThing(@QueryMap Map<String, String> params, new Callback<String> callback);
}

public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.your_layout);

   RestAdapter rest = new RestAdapter.Builder().setEndpoint(BASEPATH).build();
   API service = rest.create(API.class);

   Map<String, String> params = new HashMap<String, String>();
   params.put("key1", "val1");
   params.put("key2", "val2");
   // ... as much as you need.

   service.getMyThing(params, new Callback<String>() {
       // ... do some stuff here.
   });
}
}

The URL called will be http://www.example.com/thing/?key1=val1&key2=val2

You may have also put your console.log after an expectation that fails and is uncaught, so your log line never gets executed.

ucfagls is right, providing you use the plot() command. If not, please give us more detail.

In any case, you can control every axis seperately by using the axis() command and the xaxt/yaxt options in plot(). Using the data of ucfagls, this becomes :

plot(Y ~ X, data=foo,yaxt="n")
axis(2,cex.axis=2)

the option yaxt="n" is necessary to avoid that the plot command plots the y-axis without changing. For the x-axis, this works exactly the same :

plot(Y ~ X, data=foo,xaxt="n")
axis(1,cex.axis=2)

See also the help files ?par and ?axis

Edit : as it is for a barplot, look at the options cex.axis and cex.names :

tN <- table(sample(letters[1:5],100,replace=T,p=c(0.2,0.1,0.3,0.2,0.2)))

op <- par(mfrow=c(1,2))
barplot(tN, col=rainbow(5),cex.axis=0.5) # for the Y-axis
barplot(tN, col=rainbow(5),cex.names=0.5) # for the X-axis
par(op)

Just specify it in shared.loader or common.loader property of /conf/catalina.properties.

You can use RTRIM or cast your value to VARCHAR:

SELECT RIGHT(RTRIM(Field),3), LEFT(Field,LEN(Field)-3)

Or

SELECT RIGHT(CAST(Field AS VARCHAR(15)),3), LEFT(Field,LEN(Field)-3)

You can make a setter method in the fragment. Then in the Activity, when you reference to the fragment, you call the setter method and pass it the data from you Activity

One of the scenarios I found useful to use CTE is when you want to get DISTINCT rows of data based on one or more columns but return all columns in the table. With a standard query you might first have to dump the distinct values into a temp table and then try to join them back to the original table to retrieve the rest of the columns or you might write an extremely complex partition query that can return the results in one run but in most likelihood, it will be unreadable and cause performance issue.

But by using CTE (as answered by Tim Schmelter on Select the first instance of a record)

WITH CTE AS(
    SELECT myTable.*
    , RN = ROW_NUMBER()OVER(PARTITION BY patientID ORDER BY ID)
    FROM myTable 
)
SELECT * FROM CTE
WHERE RN = 1

As you can see, this is much easier to read and maintain. And in comparison to other queries, is much better at performance.

Look at the find command.

What you are looking for is something like

find . -name "*.xls" -type f -exec program 

Post edit

find . -name "*.xls" -type f -exec xls2csv '{}' '{}'.csv;

will execute xls2csv file.xls file.xls.csv

Closer to what you want.

I had installed Python 32 bit version and psycopg2 64 bit version to get this problem. I installed psycopg2 32 bit version and then it worked.

Earlier,I was facing problem in using jquery with React js,so I did following steps to make it working-

1. npm install jquery --save

2. Then, import $ from "jquery";

   See here

The problem is that you are attempting to define the elements in lists to multiple lists (not multiple ints as is defined). You should be defining lists like this.

int[,] list = new int[4,4] {
 {1,2,3,4},
 {5,6,7,8},
 {1,3,2,1},
 {5,4,3,2}};

You could also do

int[] list1 = new int[4] { 1, 2, 3, 4};
int[] list2 = new int[4] { 5, 6, 7, 8};
int[] list3 = new int[4] { 1, 3, 2, 1 };
int[] list4 = new int[4] { 5, 4, 3, 2 };

int[,] lists = new int[4,4] {
 {list1[0],list1[1],list1[2],list1[3]},
 {list2[0],list2[1],list2[2],list2[3]},
 etc...};

This is yet another reason to use Joda Time

new DateMidnight(2010, 3, 5)

DateMidnight is now deprecated but the same effect can be achieved with Joda Time DateTime

DateTime dt = new DateTime(2010, 3, 5, 0, 0);

Just click on "Build" on the top menu and then click on "Publish ".... Then a pop up will open and there u can define the folder which u want to save the .exe file and by clicking "Next" will allow u to set up the advanced settings... DONE!

If your file idea/workspace.xml is added to .gitignore (or its parent folder) just add it manually to git version control. Also you can add it using TortoiseGit. After the next push you will see, that your problem is solved.

you can create and initialize array of any object like this.

hero:Hero[]=[];

According SQL Server 2008 Books You can create local and global temporary tables. Local temporary tables are visible only in the current session, and global temporary tables are visible to all sessions.

'#table_temporal

'##table_global

If a local temporary table is created in a stored procedure or application that can be executed at the same time by several users, the Database Engine must be able to distinguish the tables created by the different users. The Database Engine does this by internally appending a numeric suffix to each local temporary table name.

Then there occurs no problem.

Nope.

While in debug configuration there is a DEBUG defined constant (automatically defined by Visual Studio) while there is no such constant defined for release mode. Check your project settings under build.

Selecting [Define DEBUG constant] under Project -> Build is like including #define DEBUG at the beginning of every file.

If you want to define a RELEASE constant for the release configuration go to:

• Project Properties -> Build
• Select Release Mode
• in the Conditional compilation symbols textbox enter: RELEASE

None of the above solutions worked for me and I don't have admin rights on my laptop, but they eventually led me to the git tools credential storage doc :

My setup Windows 10 | git version 2.18.0.windows.1 | Clone through HTTPS link

This solution works if you use wincred as credential helper :

> git config --global credential.helper
wincred

Changing the helper to "cache" should do the trick, as it will ask you to provide your credentials again. To set it to cache, just type :

> git config --global credential.helper cache

Check your update is active:

> git config --global credential.helper
cache

You should now be able to clone / pull / fetch as before.

First you need NameVirtualHost ip:443 in you config file! You probably have one with 80 at the end, but you will also need one with 443.

Second you need a *.domain certificate (wildcard) (it is possible to make one)

Third you can make only something.domain webs in one ip (because of the certificate)

Use PowerShell

In Windows, you can use / in your path just like Linux or macOS in all places as long as you use PowerShell as your command-line interface. It comes pre-installed on Windows and it supports many Linux commands like ls command.

If you use Windows Command Prompt (the one that appears when you type cmd in Windows Start Menu), you need to specify paths with \ just inside it. You can use / paths in all other places (code editor, Python interactive mode, etc.).

Now that Selenium 2 has been released, it's a bit easier to send an Enter key, since you can do it with the send_keys method of the selenium.webdriver.remote.webelement.WebElement class (this example code is in Python, but the same method exists in Java):

>>> from selenium import webdriver
>>> wd = webdriver.Firefox()
>>> wd.get("http://localhost/example/page")
>>> textbox = wd.find_element_by_css_selector("input")
>>> textbox.send_keys("Hello World\n")

It seems like You haven't set the Mysql server path, Set Environment Variable For MySql Server. Then restart the command prompt and enter mysql -u root-p then it asks for a password enter it. Thank you. Happy learning!

You need to install Dot Net 4.0.2 or above as mentioned here.
The 4.0 bits don't understand the syntax required by LocalDB

You can dowload the update here

You should try :

If you're using display:table-row etc., then you need proper markup, which includes a containing table. Without it your original question basically provides the equivalent bad markup of:

<tr style="width:100%">
    <td>Type</td>
    <td style="float:right">Name</td>
</tr>

Where's the table in the above? You can't just have a row out of nowhere (tr must be contained in either table, thead, tbody, etc.)

Instead, add an outer element with display:table, put the 100% width on the containing element. The two inside cells will automatically go 50/50 and align the text right on the second cell. Forget floats with table elements. It'll cause so many headaches.

markup:

<div class="view-table">
    <div class="view-row">
        <div class="view-type">Type</div>
        <div class="view-name">Name</div>                
    </div>
</div>

CSS:

.view-table
{
    display:table;
    width:100%;
}
.view-row,
{
    display:table-row;
}
.view-row > div
{
    display: table-cell;
}
.view-name 
{
    text-align:right;
}

The registry is a no-go. You're not sure whether the user which uses your application, has sufficient rights to write to the registry.

You can use the app.config file to save application-level settings (that are the same for each user who uses your application).

I would store user-specific settings in an XML file, which would be saved in Isolated Storage or in the SpecialFolder.ApplicationData directory.

Next to that, as from .NET 2.0, it is possible to store values back to the app.config file.

The ngRoute module is no longer part of the core angular.js file. If you are continuing to use $routeProvider then you will now need to include angular-route.js in your HTML:

<script src="angular.js">
<script src="angular-route.js">

API Reference

You also have to add ngRoute as a dependency for your application:

var app = angular.module('MyApp', ['ngRoute', ...]);

If instead you are planning on using angular-ui-router or the like then just remove the $routeProvider dependency from your module .config() and substitute it with the relevant provider of choice (e.g. $stateProvider). You would then use the ui.router dependency:

var app = angular.module('MyApp', ['ui.router', ...]);

If you have MATLAB Compiler installed, there's a GUI option for compiling. Try entering

deploytool

in the command line. Mathworks does a pretty good job documenting how to use it in this video tutorial: http://www.mathworks.com/products/demos/compiler/deploytool/index.html

Also, if you want to include user input such as choosing a file or directory, look into

uigetfile % or uigetdir if you need every file in a directory

for use in conjunction with

guide

You can achieve it like that:

ng-style="{ 'width' : (myObject.value == 'ok') ? '100%' : '0%' }"

Adding a file, and then deleting it is the kind of operation that's considered an error - and so SVN is telling you. You told it to expect some file data and then don't supply it when you commit, the red lights flash and the sirens go off!

The answer is to undo your add, alternatively commit the file and then use 'svn rm' to remove it from the filesystem and the repo.

On your existing button code, simply insert this line before the procedure:

If MsgBox("This will erase everything! Are you sure?", vbYesNo) = vbNo Then Exit Sub

This will force it to quit if the user presses no.

The other answers are all correct, but don't forget you could also use collection operators, as follows:

var list = [1, 2, 3, 4]
var max: Int = (list as AnyObject).valueForKeyPath("@max.self") as Int

you can also find the average in the same way:

var avg: Double = (list as AnyObject).valueForKeyPath("@avg.self") as Double

This syntax might be less clear than some of the other solutions, but it's interesting to see that -valueForKeyPath: can still be used :)

For Kotlin developers, remember the Java transient keyword becomes the built-in Kotlin @Transient annotation. Therefore, make sure you have the JPA import if you're using JPA @Transient in your entity:

import javax.persistence.Transient

1st solution (fastest) :

yourDateTime.Year % 100

2nd solution (more elegant in my opinion) :

yourDateTime.ToString("yy")

Your regular expression should look like:

/^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])[0-9a-zA-Z]{8,}$/

Here is an explanation:

/^
  (?=.*\d)          // should contain at least one digit
  (?=.*[a-z])       // should contain at least one lower case
  (?=.*[A-Z])       // should contain at least one upper case
  [a-zA-Z0-9]{8,}   // should contain at least 8 from the mentioned characters
$/

Easiest way would be to use join like this:

>>> myTuple = ['h','e','l','l','o']
>>> ''.join(myTuple)
'hello'

This works because your delimiter is essentially nothing, not even a blank space: ''.

I would imagine that it has to do with encoding. A char is 16 bytes and some encodings will use one byte for a character whereas another will use two or even more. When Java was originally designed, they assumed that any Unicode character would fit in 2 bytes, whereas now a Unicode character can require up to 4 bytes (UTF-32). There is no way for Scanner to represent a UTF-32 codepoint in a single char.

You can specify an encoding to Scanner when you construct an instance, and if not provided, it will use the platform character-set. But this still doesn't handle the issue with 3 or 4 byte Unicode characters, since they cannot be represented as a single char primitive (since char is only 16 bytes). So you would end up getting inconsistent results.

Here, Erik explains every way pass an array by reference: https://stackoverflow.com/a/5724184/5090928.

Similarly, you can create an array reference variable like so:

int arr1[] = {1, 2, 3, 4, 5};
int(&arr2)[5] = arr1;

As a general rule, pop up blockers target windows that launch without user interaction. Usually a click event can open a window without it being blocked. (unless it's a really bad popup blocker)

Try launching after a click event

Microsoft suggest several methods:

• SQL Server Data Transformation Services (DTS)
• Microsoft SQL Server 2005 Integration Services (SSIS)
• SQL Server linked servers
• SQL Server distributed queries
• ActiveX Data Objects (ADO) and the Microsoft OLE DB Provider for SQL Server
• ADO and the Microsoft OLE DB Provider for Jet 4.0

If the wizard (DTS) isn't working (and I think it should) you could try something like this http://www.devasp.net/net/articles/display/771.html which basically suggests doing something like

INSERT INTO [tblTemp] ([Column1], [Column2], [Column3], [Column4])

SELECT A.[Column1], A.[Column2], A.[Column3], A.[Column4]
FROM OPENROWSET 
('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=D:\Excel.xls;HDR=YES', 'select * from [Sheet1$]') AS A;

First loop

$v = $a[0];
$v = $a[1];
$v = $a[2];
$v = $a[3];

Yes! Current $v = $a[3] position.

Second loop

$a[3] = $v = $a[0], echo $v; // same as $a[3] and $a[0] == 'zero'
$a[3] = $v = $a[1], echo $v; // same as $a[3] and $a[1] == 'one'
$a[3] = $v = $a[2], echo $v; // same as $a[3] and $a[2] == 'two'
$a[3] = $v = $a[3], echo $v; // same as $a[3] and $a[3] == 'two'

because $a[3] is assigned by before processing.

Definitely avoid using eval to do something like this, or you will open yourself to XSS (Cross-Site Scripting) vulnerabilities.

For example, if you were to use the eval solutions proposed here, a nefarious user could send a link to their victim that looked like this:

http://yoursite.com/foo.html?func=function(){alert('Im%20In%20Teh%20Codez');}

And their javascript, not yours, would get executed. This code could do something far worse than just pop up an alert of course; it could steal cookies, send requests to your application, etc.

So, make sure you never eval untrusted code that comes in from user input (and anything on the query string id considered user input). You could take user input as a key that will point to your function, but make sure that you don't execute anything if the string given doesn't match a key in your object. For example:

// set up the possible functions:
var myFuncs = {
  func1: function () { alert('Function 1'); },
  func2: function () { alert('Function 2'); },
  func3: function () { alert('Function 3'); },
  func4: function () { alert('Function 4'); },
  func5: function () { alert('Function 5'); }
};
// execute the one specified in the 'funcToRun' variable:
myFuncs[funcToRun]();

This will fail if the funcToRun variable doesn't point to anything in the myFuncs object, but it won't execute any code.

It's really hard to tell, but one of the 9001 ads on the page may be clobbering the $ object.

jQuery provides the global jQuery object (which is present on your page). You can do the following to "get" $ back:

jQuery(document).ready(function ($) {
    // Your code here
});

If you think you're having jQuery problems, please use the debug (non-production) versions of the library.

Also, it's probably not best to be editing a live site like that ...

Recently when working on a web app for a client, I noticed that any click events added to a non-anchor element didn't work on the iPad or iPhone. All desktop and other mobile devices worked fine - but as the Apple products are the most popular mobile devices, it was important to get it fixed.

Turns out that any non-anchor element assigned a click handler in jQuery must either have an onClick attribute (can be empty like below):

onClick=""

OR

The element css needs to have the following declaration:

cursor:pointer

Strange, but that's what it took to get things working again!

Since the expiration time is zero (the third argument, the first false) the cookie is a session cookie, which will expire when the current session ends. (See the setcookie reference).

Therefore it doesn't need to be saved.

The problem is that there is no app installed to handle opening the PDF. You should use the Intent Chooser, like so:

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +"/"+ filename);
Intent target = new Intent(Intent.ACTION_VIEW);
target.setDataAndType(Uri.fromFile(file),"application/pdf");
target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

Intent intent = Intent.createChooser(target, "Open File");
try {
    startActivity(intent);
} catch (ActivityNotFoundException e) {
    // Instruct the user to install a PDF reader here, or something
}   

You can easily add a drop-shadow effect to an svg-element using the drop-shadow() CSS function and rgba color values. By using rgba color values you can change the opacity of your shadow.

img.light-shadow{_x000D_
  filter: drop-shadow(0px 3px 3px rgba(0, 0, 0, 0.4));_x000D_
}_x000D_
_x000D_
img.dark-shadow{_x000D_
  filter: drop-shadow(0px 3px 3px rgba(0, 0, 0, 1));_x000D_
}

<img class="light-shadow" src="https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-logo.svg" />_x000D_
<img class="dark-shadow" src="https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-logo.svg" />

In Galileo and Helios Provisioning Platform were introduced, and non-update-site plugins now should be placed in "dropins" subfolder ("eclipse/dropins/plugin_name/features", "eclipse/dropins/plugin_name/plugins") instead of Eclipse's folder ("eclipse/features" and "eclipse/plugins").

Also for programming needs the best Eclipse is the latest Eclipse. It has too many bugs for now, and all the Eclipse team is now doing is fixing the bugs. There are very few interface enhancements since Europa. IMHO.

What happened to me is I was exporting a function like this:

module.exports = () => {
    const method = async (req, res) => {
    }
    return {
        method
    }
}

but I was calling it like this:

const main = require('./module');

instead

const main = require('./module')();

You can convert type of plaintext to string:

f.write(str(plaintext) + '\n')

In case you have a dump made with sqlplus and the output is garbled as someone did not set those 3 values before, there's a way out.

Just a couple hours ago DB admin send me that ugly looking output of query executed in sqlplus (I dunno, maybe he hates me...). I had to find a way out: this is an awk script to parse that output to make it at least more readable. It's far not perfect, but I did not have enough time to polish it properly. Anyway, it does the job quite well.

awk ' function isDashed(ln){return ln ~ /^---+/};function addLn(){ln2=ln1; ln1=ln0;ln0=$0};function isLoaded(){return l==1||ln2!=""}; function printHeader(){hdr=hnames"\n"hdash;if(hdr!=lastHeader){lastHeader=hdr;print hdr};hnames="";hdash=""};function isHeaderFirstLn(){return isDashed(ln0) && !isDashed(ln1) && !isDashed(ln2) }; function isDataFirstLn(){return isDashed(ln2)&&!isDashed(ln1)&&!isDashed(ln0)}                         BEGIN{_d=1;h=1;hnames="";hdash="";val="";ln2="";ln1="";ln0="";fheadln=""}                                 { addLn();  if(!isLoaded()){next}; l=1;             if(h==1){if(!isDataFirstLn()){if(_d==0){hnames=hnames" "ln1;_d=1;}else{hdash=hdash" "ln1;_d=0}}else{_d=0;h=0;val=ln1;printHeader()}}else{if(!isHeaderFirstLn()){val=val" "ln1}else{print val;val="";_d=1;h=1;hnames=ln1}}   }END{if(val!="")print val}'

In case anyone else would like to try improve this script, below are the variables: hnames -- column names in the header, hdash - dashed below the header, h -- whether I'm currently parsing header (then ==1), val -- the data, _d - - to swap between hnames and hdash, ln0 - last line read, ln1 - line read previously (it's the one i'm actually working with), ln2 - line read before ln1

Happy parsing!

Oh, almost forgot... I use this to prettify sqlplus output myself:

[oracle@ora ~]$ cat prettify_sql 
set lines 256
set trimout on
set tab off
set pagesize 100
set colsep " | "

colsep is optional, but it makes output look like sqlite which is easier to parse using scripts.

EDIT: A little preview of parsed and non-parsed output

You might use flush to force validation constraints to be realised and detected in a known place rather than when the transaction is committed. It may be that commit gets called implicitly by some framework logic, through declarative logic, the container, or by a template. In this case, any exception thrown may be difficult to catch and handle (it could be too high in the code).

For example, if you save() a new EmailAddress object, which has a unique constraint on the address, you won't get an error until you commit.

Calling flush() forces the row to be inserted, throwing an Exception if there is a duplicate.

However, you will have to roll back the session after the exception.

If you plan using background images a lot throughout your project you may find it useful to create a really simple custom pipe that will create the url for you.

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'asUrl'
})
export class BackgroundUrlPipe implements PipeTransform {

  transform(value: string): string {
    return `url(./images/${value})`
  }

}

Then you can add background images without all the string concatenation.

<div [ngStyle]="{ background: trls.img | asUrl }"></div>

You can just use the -R (recursive) flag.

chmod -R 777 /Users/Test/Desktop/PATH

Get your object's constructor function and then inspect its name property.

myObj.constructor.name

Returns "myClass".

I had the same problem running Ubuntu 18.04. I tried multiple solutions but my device (OnePlus 5T) was always unauthorized.

Solution

1. Configure udev rules on Ubuntu. To do this, just follow the official documentation: https://developer.android.com/studio/run/device

   The idVendor of my device (OnePlus) is not listed. To get it, just connect your device and use lsusb:

   Bus 003 Device 008: ID 2a70:4ee7

   In this example, 2a70 is the idVendor.

2. Remove existing adb keys on Ubuntu:

   rm -v ~/.android/adbkey* ~/.android/adbkey ~/.android/adbkey.pub

3. 'Revoke USB debugging authorizations' on your device configuration (developer options).

4. Finally, restart the adb server to create a new key:

   sudo adb kill-server sudo adb devices

After that, I got the authorization prompt on my device and I authorized it.

I'm going to show you an example that will help you to understand why it's important.

Such as you have some Box Widgets and you want to show some hidden content inside every single widget. You can do this easily when you have a different CSS class for the single widget but when it has the same class how can you do that?
Actually, that's why we use $(this)

PHP_EOL is a predefined constant in PHP since PHP 4.3.10 and PHP 5.0.2. See the manual posting:

Using this will save you extra coding on cross platform developments.

IE.

$data = 'some data'.PHP_EOL;
$fp = fopen('somefile', 'a');
fwrite($fp, $data);

If you looped through this twice you would see in 'somefile':

some data
some data

When a method was requested, it will have an array. So simply check with count().

$m=['GET'=>$_GET,'POST'=>$_POST];
foreach($m as$k=>$v){
    echo count($v)?
    $k.' was requested.':null;
}

How about using grep -E?

echo "This is 02G05 a test string 20-Jul-2012" | grep -Eo '[0-9]+G[0-9]+'

select controls are still clickable even on readonly attrib

if you want to still disable the control but you want its value posted. You might consider creating a hidden field. with the same value as your control.

then create a jquery, on select change

$('#your_select_id').change(function () {
    $('#your_hidden_selectid').val($('#your_select_id').val());
});

If you're using Google Chrome you can use the Chrome Dev Editor: https://github.com/dart-lang/chromedeveditor

ng-init is a directive that can be placed inside div's, span's, whatever, whereas onload is an attribute specific to the ng-include directive that functions as an ng-init. To see what I mean try something like:

<span onload="a = 1">{{ a }}</span>
<span ng-init="b = 2">{{ b }}</span>

You'll see that only the second one shows up.

An isolated scope is a scope which does not prototypically inherit from its parent scope. In laymen's terms if you have a widget that doesn't need to read and write to the parent scope arbitrarily then you use an isolate scope on the widget so that the widget and widget container can freely use their scopes without overriding each other's properties.

Your code is fine, I suspect your problem is how you are launching it.

You need to launch python from your '2014_07_13_test' directory.

Open up a command prompt and 'cd' into your '2014_07_13_test' directory.

For instance:

$ cd /path/to/2014_07_13_test
$ python test.py

If you cannot 'cd' into the directory like this you can add it to sys.path

In test.py:

import sys, os
sys.path.append('/path/to/2014_07_13_test')

Or set/edit the PYTHONPATH

And all should be well...

...well there is a slight mistake with your 'shebang' lines (the first line in both your files), there shouldn't be a space between the '#' and the '!'

There is a better shebang you should use.

Also you don't need the shebang line on every file... only the ones you intend to run from your shell as executable files.

module Enumerable
  def map_with_index(&block)
    i = 0
    self.map { |val|
      val = block.call(val, i)
      i += 1
      val
    }
  end
end

["foo", "bar"].map_with_index {|item, index| [item, index] } => [["foo", 0], ["bar", 1]]

If your table has enough columns then you can try this. First create a new table with preferred order of columns.

    create table new as select column1,column2,column3,....columnN from table_name;

Now drop the table using drop command

    drop table table_name;

now rename the newly created table to your old table name.

    rename new to table_name;

now select the table, you have your columns rearranged as you preferred before.

    select * from table_name;

For recent versions of Gradle (I tested with the 6.4.1 version):

gradle dependencies --configuration compileClasspath

or if you're using the Gradle Wrapper:

gradlew dependencies --configuration compileClasspath

When building for Android with the 'debug' and 'release' compilation profiles, the debugCompileClasspath and releaseCompileClasspath configurations can be used instead of compileClasspath.

In Eclipse: right-click on your project -> Export -> JAR file

At last page with options (when there will be no Next button active) you will see settings for Main class:. You need to set here class with main method which should be executed by default (like when JAR file will be double-clicked).

You don't need to pass the quotes enclosing the custom headers to curl. Also, your variables in the middle of the data argument should be quoted.

First, write a function that generates the post data of your script. This saves you from all sort of headaches concerning shell quoting and makes it easier to read an maintain the script than feeding the post data on curl's invocation line as in your attempt:

generate_post_data()
{
  cat <<EOF
{
  "account": {
    "email": "$email",
    "screenName": "$screenName",
    "type": "$theType",
    "passwordSettings": {
      "password": "$password",
      "passwordConfirm": "$password"
    }
  },
  "firstName": "$firstName",
  "lastName": "$lastName",
  "middleName": "$middleName",
  "locale": "$locale",
  "registrationSiteId": "$registrationSiteId",
  "receiveEmail": "$receiveEmail",
  "dateOfBirth": "$dob",
  "mobileNumber": "$mobileNumber",
  "gender": "$gender",
  "fuelActivationDate": "$fuelActivationDate",
  "postalCode": "$postalCode",
  "country": "$country",
  "city": "$city",
  "state": "$state",
  "bio": "$bio",
  "jpFirstNameKana": "$jpFirstNameKana",
  "jpLastNameKana": "$jpLastNameKana",
  "height": "$height",
  "weight": "$weight",
  "distanceUnit": "MILES",
  "weightUnit": "POUNDS",
  "heightUnit": "FT/INCHES"
}
EOF
}

It is then easy to use that function in the invocation of curl:

curl -i \
-H "Accept: application/json" \
-H "Content-Type:application/json" \
-X POST --data "$(generate_post_data)" "https://xxx:[email protected]/xxxxx/xxxx/xxxx"

This said, here are a few clarifications about shell quoting rules:

The double quotes in the -H arguments (as in -H "foo bar") tell bash to keep what's inside as a single argument (even if it contains spaces).

The single quotes in the --data argument (as in --data 'foo bar') do the same, except they pass all text verbatim (including double quote characters and the dollar sign).

To insert a variable in the middle of a single quoted text, you have to end the single quote, then concatenate with the double quoted variable, and re-open the single quote to continue the text: 'foo bar'"$variable"'more foo'.

As said in JavaDocs:

If the mapped keys contains duplicates (according to Object.equals(Object)), an IllegalStateException is thrown when the collection operation is performed. If the mapped keys may have duplicates, use toMap(Function keyMapper, Function valueMapper, BinaryOperator mergeFunction) instead.

So you should use toMap(Function keyMapper, Function valueMapper, BinaryOperator mergeFunction) instead. Just provide a merge function, that will determine which one of duplicates is put in the map.

For example, if you don't care which one, just call

Map<String, String> phoneBook = 
        people.stream()
              .collect(Collectors.toMap(Person::getName, 
                                        Person::getAddress, 
                                        (a1, a2) -> a1));

The class which implements KeyListener interface becomes our custom key event listener. This listener can not directly listen the key events. It can only listen the key events through intermediate objects such as JFrame. So

1. Make one Key listener class as

   class MyListener implements KeyListener{
   
      // override all the methods of KeyListener interface.
   }
   

2. Now our class MyKeyListener is ready to listen the key events. But it can not directly do so.

3. Create any object like JFrame object through which MyListener can listen the key events. for that you need to add MyListener object to the JFrame object.

   JFrame f=new JFrame();
   f.addKeyListener(new MyKeyListener);
   

TL;DR To fix this issue, invoke packaging plugin before, e.g. for jar packaging use maven-jar-plugin , as following:

mvn jar:jar install:install

Or

mvn jar:jar deploy:deploy 

If you actually needed to deploy.

Gotcha This approach won't work if you have multi-module project with different packagings (ear/war/jar/zip) – even worse, wrong artifacts will be installed/deployed! In such case use reactor options to only build the deployable module (e.g. the war).

Explanation

In some cases you actually want to run directly a install:install or deploy:deploy goal (that is, from the maven-deploy-plugin, the deploy goal, not the Maven deploy phase) and you would end up in the annoying The packaging for this project did not assign a file to the build artifact.

A classic example is a CI job (a Jenkins or Bamboo job, e.g.) where in different steps you want to execute/care about different aspects:

• A first step would be a mvn clean install, performing tests and test coverage
• A second step would be a Sonarqube analysis based on a quality profile, e.g. mvn sonar:sonar plus further options
• Then, and only after successful tests execution and quality gate passed, you want to deploy to your Maven enterprise repository the final project artifacts, yet you don't want to re-run mvn deploy, because it would again execute previous phases (and compile, test, etc.) and you want your build to be effective but yet fast.

Yes, you could speed up this last step at least skipping tests (compilation and execution, via -Dmaven.test.skip=true) or play with a particular profile (to skip as many plugins as possible), but it is much easier and clear to simply run mvn deploy:deploy then.

But it would fail with the error above, because as also specified by the plugin FAQ:

During the packaging-phase all gathered and placed in context. With this mechanism Maven can ensure that the maven-install-plugin and maven-deploy-plugin are copying/uploading the same set of files. So when you only execute deploy:deploy, then there are no files put in the context and there is nothing to deploy.

Indeed, the deploy:deploy needs some runtime information placed in the build context by previous phases (or previous plugins/goals executions).

It has also reported as a potential bug: MDEPLOY-158: deploy:deploy does not work for only Deploying artifact to Maven Remote repo

But then rejected as not a problem.

The deployAtEnd configuration option of the maven-deploy-plugin won't help neither in certain scenarios because we have intermediate job steps to execute:

Whether every project should be deployed during its own deploy-phase or at the end of the multimodule build. If set to true and the build fails, none of the reactor projects is deployed. (experimental)

So, how to fix it?
Simply run the following in such a similar third/last step:

mvn jar:jar deploy:deploy

The maven-jar-plugin will not re-create any jar as part of your build, thanks to its forceCreation option set to false by default:

Require the jar plugin to build a new JAR even if none of the contents appear to have changed. By default, this plugin looks to see if the output jar exists and inputs have not changed. If these conditions are true, the plugin skips creation of the jar.

But it will nicely populate the build context for us and make deploy:deploy happy. No tests to skip, no profiles to add. Just what you need: speed.

Additional note: if you are using the build-helper-maven-plugin, buildnumber-maven-plugin or any other similar plugin to generate meta-data later on used by the maven-jar-plugin (e.g. entries for the Manifest file), you most probably have executions linked to the validate phase and you still want to have them during the jar:jar build step (and yet keep a fast execution). In this case the almost harmless overhead is to invoke the validate phase as following:

mvn validate jar:jar deploy:deploy

Yet another additional note: if you have not jar but, say, war packaging, use war:war before install/deploy instead.

Gotcha as pointed out above, check behavior in multi module projects.

(Posted on behalf of the OP).

I believe I figured it out.

In my case, I added [class*="col-"] {padding: 0 7.5px;};.

Then added .row {margin: 0 -7.5px;}.

This works pretty well, except there is 1px margin on both sides. So I just make .row {margin: 0 -7.5px;} to .row {margin: 0 -8.5px;}, then it works perfectly.

I have no idea why there is a 1px margin. Maybe someone can explain it?

See the sample I created:

Demo
Code

Dim strFirstAddress As String
Dim searchlast As Range
Dim search As Range

Set search = ActiveSheet.Range("A1:A100")
Set searchlast = search.Cells(search.Cells.Count)

Set rngFindValue = ActiveSheet.Range("A1:A100").Find(Text, searchlast, xlValues)
If Not rngFindValue Is Nothing Then
  strFirstAddress = rngFindValue.Address
  Do
    Set rngFindValue = search.FindNext(rngFindValue)
  Loop Until rngFindValue.Address = strFirstAddress

This will add an image to another.

using (Graphics grfx = Graphics.FromImage(image))
{
    grfx.DrawImage(newImage, x, y)
}

Graphics is in the namespace System.Drawing

If I get you right, you need ..\..\src

If you follow your link, it tells you that the error results from the $injector not being able to resolve your dependencies. This is a common issue with angular when the javascript gets minified/uglified/whatever you're doing to it for production.

The issue is when you have e.g. a controller;

angular.module("MyApp").controller("MyCtrl", function($scope, $q) {
  // your code
})

The minification changes $scope and $q into random variables that doesn't tell angular what to inject. The solution is to declare your dependencies like this:

angular.module("MyApp")
  .controller("MyCtrl", ["$scope", "$q", function($scope, $q) {
  // your code
}])

That should fix your problem.

Just to re-iterate, everything I've said is at the link the error message provides to you.

on first button add the following.

onclick="window.location.href='Students.html';"

similarly do the rest 2 buttons.

<input type="button" value="Add Students" onclick="window.location.href='Students.html';"> 
<input type="button" value="Add Courses" onclick="window.location.href='Courses.html';"> 
<input type="button" value="Student Payments" onclick="window.location.href='Payments.html';">

Using awk only

foo="uNcapItalizedstrIng"
echo $foo | awk '{print toupper(substr($0,0,1))tolower(substr($0,2))}'

If you've already pushed things to a remote server (and you have other developers working off the same remote branch) the important thing to bear in mind is that you don't want to rewrite history

Don't use git reset --hard

You need to revert changes, otherwise any checkout that has the removed commits in its history will add them back to the remote repository the next time they push; and any other checkout will pull them in on the next pull thereafter.

If you have not pushed changes to a remote, you can use

git reset --hard <hash>

If you have pushed changes, but are sure nobody has pulled them you can use

git reset --hard
git push -f

If you have pushed changes, and someone has pulled them into their checkout you can still do it but the other team-member/checkout would need to collaborate:

(you) git reset --hard <hash>
(you) git push -f

(them) git fetch
(them) git reset --hard origin/branch

But generally speaking that's turning into a mess. So, reverting:

The commits to remove are the lastest

This is possibly the most common case, you've done something - you've pushed them out and then realized they shouldn't exist.

First you need to identify the commit to which you want to go back to, you can do that with:

git log

just look for the commit before your changes, and note the commit hash. you can limit the log to the most resent commits using the -n flag: git log -n 5

Then reset your branch to the state you want your other developers to see:

git revert  <hash of first borked commit>..HEAD

The final step is to create your own local branch reapplying your reverted changes:

git branch my-new-branch
git checkout my-new-branch
git revert <hash of each revert commit> .

Continue working in my-new-branch until you're done, then merge it in to your main development branch.

The commits to remove are intermingled with other commits

If the commits you want to revert are not all together, it's probably easiest to revert them individually. Again using git log find the commits you want to remove and then:

git revert <hash>
git revert <another hash>
..

Then, again, create your branch for continuing your work:

git branch my-new-branch
git checkout my-new-branch
git revert <hash of each revert commit> .

Then again, hack away and merge in when you're done.

You should end up with a commit history which looks like this on my-new-branch

2012-05-28 10:11 AD7six             o [my-new-branch] Revert "Revert "another mistake""
2012-05-28 10:11 AD7six             o Revert "Revert "committing a mistake""
2012-05-28 10:09 AD7six             o [master] Revert "committing a mistake"
2012-05-28 10:09 AD7six             o Revert "another mistake"
2012-05-28 10:08 AD7six             o another mistake
2012-05-28 10:08 AD7six             o committing a mistake
2012-05-28 10:05 Bob                I XYZ nearly works

Better way®

Especially that now that you're aware of the dangers of several developers working in the same branch, consider using feature branches always for your work. All that means is working in a branch until something is finished, and only then merge it to your main branch. Also consider using tools such as git-flow to automate branch creation in a consistent way.

While the other answers have not worked for me in all situations, the best solution I could find (working with POST as well), taken from here:

curl -vs 'https://some-site.com' 1> /dev/null

For any Single File Component users, here is how I set up global variable(s)

1. Assuming you are using Vue-Cli's webpack template

2. Declare your variable(s) in somewhere variable.js

   const shallWeUseVuex = false;
   

3. Export it in variable.js

   module.exports = { shallWeUseVuex : shallWeUseVuex };
   

4. Require and assign it in your vue file

   export default {
       data() {
           return {
               shallWeUseVuex: require('../../variable.js')
           };
       }
   }

You might want to take a look at Joda Time which is a really good API for dealing with date/time. Even though if you don't really need it for the solution to your current question it is bound to save you pain in the future.

if (($("#one").length > 0)){
   alert('yes');
}

if (($("#two").length > 0)){
   alert('yes');
}

if (($("#three").length > 0)){
   alert('yes');
}

if (($("#four")).length == 0){
   alert('no');
}

This is what you need :)

You can also add (keyup.enter)="xxxx()"

So... if you are running your containers using a Rancher server, Rancher v1.6 (not sure if 2.0 has this) containers have access to http://rancher-metadata/ which has a lot of useful information.

From inside the container the IP address can be found here: curl http://rancher-metadata/latest/self/host/agent_ip

For more details see: https://rancher.com/docs/rancher/v1.6/en/rancher-services/metadata-service/

You can save image , save the file in your current directory application and move the file to any directory .

 Bitmap btm = new Bitmap(image.width,image.height);
    Image img = btm;
                        img.Save(@"img_" + x + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
                        FileInfo img__ = new FileInfo(@"img_" + x + ".jpg");
                        img__.MoveTo("myVideo\\img_" + x + ".jpg");

        FileStream fs =
            new FileStream(Server.MapPath(@"\Content\NPOITemplate.xls"), FileMode.Open, FileAccess.Read);

        // Getting the complete workbook...
        HSSFWorkbook templateWorkbook = new HSSFWorkbook(fs, true);

        // Getting the worksheet by its name...
        HSSFSheet sheet = templateWorkbook.GetSheet("Sheet1");

        // Getting the row... 0 is the first row.
        HSSFRow dataRow = sheet.GetRow(4);

        // Setting the value 77 at row 5 column 1
        dataRow.GetCell(0).SetCellValue(77);

        // Forcing formula recalculation...
        sheet.ForceFormulaRecalculation = true;

        MemoryStream ms = new MemoryStream();

        // Writing the workbook content to the FileStream...
        templateWorkbook.Write(ms);

        TempData["Message"] = "Excel report created successfully!";

        // Sending the server processed data back to the user computer...
        return File(ms.ToArray(), "application/vnd.ms-excel", "NPOINewFile.xls");
    }
    catch(Exception ex)
    {
        TempData["Message"] = "Oops! Something went wrong.";

        return RedirectToAction("NPOI");
    }
}

There is the hint feature? You can use the setHint() to set it, or set it in XML (though you probably don't want that, because the XML doesn't 'know' the name/adress of your user :) )

I was having the same error because I had a space at the end of my filename(not the reference but the actual filename). Once I changed 'app.js ' to 'app.js' it worked fine.

$('#message').load('index.php?pg=ajaxFlashcard', null, showResponse);

function showResponse() {
    hideLoad();

Microsoft has a vey ry neat guide on how to remove duplicates. Check out http://support.microsoft.com/kb/139444

In brief, here is the easiest way to delete duplicates when you have just a few rows to delete:

SET rowcount 1;
DELETE FROM t1 WHERE myprimarykey=1;

myprimarykey is the identifier for the row.

I set rowcount to 1 because I only had two rows that were duplicated. If I had had 3 rows duplicated then I would have set rowcount to 2 so that it deletes the first two that it sees and only leaves one in table t1.

Hope it helps anyone

All of these answers are a good way, but I don't think you want to always go to your DB and modify the default value that you have set to NULL.

I suggest you go to the app/User.php and modify the protected $fillable so it will take your new fields in the data array used to register.

Let's say you add a new input field called "first_name", your $fillable should be something like this :

protected $fillable = [ 'first_name', 'email', 'password',]; 

This did it for me. Good luck!

You could also achieve that by renaming the columns:

df.columns = ['a', 'b']

This involves a manual step but could be an option especially if you would eventually rename your data frame.

Main issue is that you first need to set the location of your x and y ticks. Also, it helps to use the more object-oriented interface to matplotlib. Namely, interact with the axes object directly.

import matplotlib.pyplot as plt
import numpy as np
column_labels = list('ABCD')
row_labels = list('WXYZ')
data = np.random.rand(4,4)
fig, ax = plt.subplots()
heatmap = ax.pcolor(data)

# put the major ticks at the middle of each cell, notice "reverse" use of dimension
ax.set_yticks(np.arange(data.shape[0])+0.5, minor=False)
ax.set_xticks(np.arange(data.shape[1])+0.5, minor=False)


ax.set_xticklabels(row_labels, minor=False)
ax.set_yticklabels(column_labels, minor=False)
plt.show()

Hope that helps.

[100 %]Solved. I had the same problem today. I checked my server space

df-h

I saw that server is out of space so i check which directory has most size by

sudo du -ch / | sort -h

I saw 12.2G /var/lib/jenkins so i entered this folder and cleared all the logs by

cd /var/libs/jenkins
rm *

and restart the jenkins it will work normal

sudo systemctl restart jenkins.service

This is working for me, Writing(creating as well) and/or appending content in the same mode.

$fp = fopen("MyFile.txt", "a+") 

find -L /var/www/ -type l

# man find

-L     Follow  symbolic links.  When find examines or prints information about files, the information used shall be taken from the

properties of the file to which the link points, not from the link itself (unless it is a broken symbolic link or find is unable to examine the file to which the link points). Use of this option implies -noleaf. If you later use the -P option, -noleaf will still be in effect. If -L is in effect and find discovers a symbolic link to a subdirectory during its search, the subdirectory pointed to by the symbolic link will be searched.

let plainData = plainString.dataUsingEncoding(NSUTF8StringEncoding)
let base64String = plainData?.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))
print(base64String!) // Zm9v

Decoding

let decodedData = NSData(base64EncodedString: base64String!, options: NSDataBase64DecodingOptions(rawValue: 0))
let decodedString = NSString(data: decodedData, encoding: NSUTF8StringEncoding)
print(decodedString) // foo

Objective-C

NSString *plainString = @"foo";

Encoding

NSData *plainData = [plainString dataUsingEncoding:NSUTF8StringEncoding];
NSString *base64String = [plainData base64EncodedStringWithOptions:0];
NSLog(@"%@", base64String); // Zm9v

Decoding

NSData *decodedData = [[NSData alloc] initWithBase64EncodedString:base64String options:0];
NSString *decodedString = [[NSString alloc] initWithData:decodedData encoding:NSUTF8StringEncoding];
NSLog(@"%@", decodedString); // foo 

Let said our backend looks like this:

public async Task<IActionResult> Post([FromBody] IList<UserRol> roles, string notes) {
}

We have a HttpService like this:

    post<T>(url: string, body: any, headers?: HttpHeaders, params?: HttpParams): Observable<T> {
        return this.http.post<T>(url, body, { headers: headers, params});
    }

Following is how we can pass the body and the notes as parameter: // how to call it

const headers: HttpHeaders = new HttpHeaders({
    'Authorization': `Bearer XXXXXXXXXXXXXXXXXXXXXXXXXXX`
});

const bodyData = this.getBodyData(); // get whatever we want to send as body

let params: HttpParams = new HttpParams();
params = params.set('notes', 'Some notes to send');

this.httpService.post<any>(url, bodyData, headers, params);

It worked for me (using angular 7^), I hope is useful for somebody.

What SSL private key should be sent along with the client certificate?

None of them :)

One of the appealing things about client certificates is it does not do dumb things, like transmit a secret (like a password), in the plain text to a server (HTTP basic_auth). The password is still used to unlock the key for the client certificate, its just not used directly to during exchange or tp authenticate the client.

Instead, the client chooses a temporary, random key for that session. The client then signs the temporary, random key with his cert and sends it to the server (some hand waiving). If a bad guy intercepts anything, its random so it can't be used in the future. It can't even be used for a second run of the protocol with the server because the server will select a new, random value, too.

Fails with: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure

Use TLS 1.0 and above; and use Server Name Indication.

You have not provided any code, so its not clear to me how to tell you what to do. Instead, here's the OpenSSL command line to test it:

openssl s_client -connect www.example.com:443 -tls1 -servername www.example.com \
    -cert mycert.pem -key mykey.pem -CAfile <certificate-authority-for-service>.pem

You can also use -CAfile to avoid the “verify error:num=20”. See, for example, “verify error:num=20” when connecting to gateway.sandbox.push.apple.com.

Perhaps you could think about the problem in a different way. WebClient and HttpClient are essentially different implementations of the same thing. What I recommend is implementing the Dependency Injection pattern with an IoC Container throughout your application. You should construct a client interface with a higher level of abstraction than the low level HTTP transfer. You can write concrete classes that use both WebClient and HttpClient, and then use the IoC container to inject the implementation via config.

What this would allow you to do would be to switch between HttpClient and WebClient easily so that you are able to objectively test in the production environment.

So questions like:

Will HttpClient be a better design choice if we upgrade to .Net 4.5?

Can actually be objectively answered by switching between the two client implementations using the IoC container. Here is an example interface that you might depend on that doesn't include any details about HttpClient or WebClient.

HttpClient Implementation

You can use Task.Run to make WebClient run asynchronously in its implementation.

Dependency Injection, when done well helps alleviate the problem of having to make low level decisions upfront. Ultimately, the only way to know the true answer is try both in a live environment and see which one works the best. It's quite possible that WebClient may work better for some customers, and HttpClient may work better for others. This is why abstraction is important. It means that code can quickly be swapped in, or changed with configuration without changing the fundamental design of the app.

BTW: there are numerous other reasons that you should use an abstraction instead of directly calling one of these low-level APIs. One huge one being unit-testability.

What about using extension method?

public static class StringExtensions
{
   public static string Repeat(this char chatToRepeat, int repeat) {

       return new string(chatToRepeat,repeat);
   }
   public  static string Repeat(this string stringToRepeat,int repeat)
   {
       var builder = new StringBuilder(repeat*stringToRepeat.Length);
       for (int i = 0; i < repeat; i++) {
           builder.Append(stringToRepeat);
       }
       return builder.ToString();
   }
}

You could then write :

Debug.WriteLine('-'.Repeat(100)); // For Chars  
Debug.WriteLine("Hello".Repeat(100)); // For Strings

Note that a performance test of using the stringbuilder version for simple characters instead of strings gives you a major preformance penality : on my computer the difference in mesured performance is 1:20 between: Debug.WriteLine('-'.Repeat(1000000)) //char version and
Debug.WriteLine("-".Repeat(1000000)) //string version

Here's a Mootools solution doing the same as Alessandro's - replaces each affected input with a new one.

if (Browser.chrome) {
    $$('input:-webkit-autofill').each(function(item) {
        var text = item.value;
        var name = item.get('name');
        var newEl = new Element('input');
        newEl.set('name', name);
        newEl.value = text;
        newEl.replaces(item);
    });
}

A quick way to do it in sql server 2012 is as follows:

SELECT FORMAT(GETDATE() , 'dd/MM/yyyy HH:mm:ss')

If you are using the Postgres Mac app (by Heroku) and Bundler, you can add the pg_config directly inside the app, to your bundle.

bundle config build.pg --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.4/bin/pg_config

...then run bundle again.

Note: check the version first using the following.

ls /Applications/Postgres.app/Contents/Versions/

The best source is probably Apple's official documentation. The specific variable you are looking for is CONFIGURATION.

I think this might be the simplest solution:

<tr onclick="location.href='http://www.mywebsite.com'" style="cursor: pointer">
<td>...</td>
<td>...</td>
</tr>

The cursor CSS property sets the type of cursor, if any, to show when the mouse pointer is over an element.

The inline css defines that for that element the cursor will be formatted as a pointer, so you don't need the 'hover'.

you need to join the two tables:

for instance you want to copy the value of name from tableA into tableB where they have the same ID

UPDATE tableB t1 
        INNER JOIN tableA t2 
             ON t1.id = t2.id
SET t1.name = t2.name 
WHERE t2.name = 'Joe'

UPDATE 1

UPDATE tableB t1 
        INNER JOIN tableA t2 
             ON t1.id = t2.id
SET t1.name = t2.name 

UPDATE 2

UPDATE tableB t1 
        INNER JOIN tableA t2 
             ON t1.name = t2.name
SET t1.value = t2.value

there is an official YouTube Android Player API wich you can use. This is a bit more complicated but it is working better than other solutions using webclients.

First you must register your app in Googles API Console. This is completely free until your app gets over 25k request a month (or something like that). There are complete anf great tutorials under the link. I hope you can understand them. If not, ask! :)

Creat XML called border.xml in drawable folder as below :

<?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item> 
    <shape android:shape="rectangle">
      <solid android:color="#FF0000" /> 
    </shape>
  </item>   
    <item android:left="5dp" android:right="5dp"  android:top="5dp" >  
     <shape android:shape="rectangle"> 
      <solid android:color="#000000" />
    </shape>
   </item>    
 </layer-list>

then add this to linear layout as backgound as this:

     android:background="@drawable/border"

The antonym of Hard-Coding is Soft-Coding. For a better understanding of Hard Coding, I will introduce both terms.

• Hard-coding: feature is coded to the system not allowing for configuration;
• Parametric: feature is configurable via table driven, or properties files with limited parametric values ;
• Soft-coding: feature uses “engines” that derive results based on any number of parametric values (e.g. business rules in BRE); rules are coded but exist as parameters in system, written in script form

Examples:

// firstName has a hard-coded value of "hello world"
string firstName = "hello world";

// firstName has a non-hard-coded provided as input
Console.WriteLine("first name :");
string firstName = Console.ReadLine();

A hard-coded constant^[1]:

float areaOfCircle(int radius)
{
    float area = 0;
    area = 3.14*radius*radius;  //  3.14 is a hard-coded value
    return area;
}

Additionally, hard-coding and soft-coding could be considered to be anti-patterns^[2]. Thus, one should strive for balance between hard and soft-coding.

1. Hard Coding “Hard coding” is a well-known antipattern against which most web development books warns us right in the preface. Hard coding is the unfortunate practice in which we store configuration or input data, such as a file path or a remote host name, in the source code rather than obtaining it from a configuration file, a database, a user input, or another external source.
   
   The main problem with hard code is that it only works properly in a certain environment, and at any time the conditions change, we need to modify the source code, usually in multiple separate places.
   
   
2. Soft Coding
   If we try very hard to avoid the pitfall of hard coding, we can easily run into another antipattern called “soft coding”, which is its exact opposite.
   
   In soft coding, we put things that should be in the source code into external sources, for example we store business logic in the database. The most common reason why we do so, is the fear that business rules will change in the future, therefore we will need to rewrite the code.
   
   In extreme cases, a soft coded program can become so abstract and convoluted that it is almost impossible to comprehend it (especially for new team members), and extremely hard to maintain and debug.

Inspired by an article discussing immutable implementations of recursive data structures I put an alternate solution together using Swift.

The leading answer documents solution by highlighting the following topics:

1. What is the reverse of nil (the empty list)?
   • Does not matter here, because we have nil protection in Swift.
2. What is the reverse of a one element list?
   • The element itself
3. What is the reverse of an n element list?
   • The reverse of the second element on followed by the first element.

I have called these out where applicable in the solution below.

/**
 Node is a class that stores an arbitrary value of generic type T 
 and a pointer to another Node of the same time.  This is a recursive 
 data structure representative of a member of a unidirectional linked
 list.
 */
public class Node<T> {
    public let value: T
    public let next: Node<T>?

    public init(value: T, next: Node<T>?) {
        self.value = value
        self.next = next
    }

    public func reversedList() -> Node<T> {
        if let next = self.next {
            // 3. The reverse of the second element on followed by the first element.
            return next.reversedList() + value
        } else {
            // 2. Reverse of a one element list is itself
            return self
        }
    }
}

/**
 @return Returns a newly created Node consisting of the lhs list appended with rhs value.
 */
public func +<T>(lhs: Node<T>, rhs: T) -> Node<T> {
    let tail: Node<T>?
    if let next = lhs.next {
        // The new tail is created recursively, as long as there is a next node.
        tail = next + rhs
    } else {
        // If there is not a next node, create a new tail node to append
        tail = Node<T>(value: rhs, next: nil)
    }
    // Return a newly created Node consisting of the lhs list appended with rhs value.
    return Node<T>(value: lhs.value, next: tail)
}

For the the accepted answer of @Joseph Silber is not working, because indexOf returns -1. This is probably because Angular adds an hashkey, which is different for my $scope.items[0] and my item. I tried to resolve this with the angular.toJson() function, but it did not work :(

Ah, I found out the reason... I use a chunk method to create two columns in my table by watching my $scope.items. Sorry!

Personally I'd json_encode the array (taking into account any escaping etc needed) and bung the entire lot into an appropriately sized text/blob field.

It makes it very easy to store "unstructured" data but a real PITA to search/index on with any grace.

A simple json_decode will "explode" the data back into an array for you.

You need to use anchors to match the beginning of the string ^ and the end of the string $

^[0-9]{2}$

Just a word on drawing (incorrect) conclusions from any of the performance measurement commands referred to in the answers. There are a number of pitfalls that should taken in consideration aside from looking to the bare invocation time of a (custom) function or command.

Sjoemelsoftware

_{'Sjoemelsoftware' voted Dutch word of the year 2015
Sjoemelen means cheating, and the word sjoemelsoftware came into being due to the Volkswagen emissions scandal. The official definition is "software used to influence test results".}

Personally, I think that "Sjoemelsoftware" is not always deliberately created to cheat test results but might originate from accommodating practical situation that are similar to test cases as shown below.

As an example, using the listed performance measurement commands, Language Integrated Query (LINQ)⁽¹⁾, is often qualified as the fasted way to get something done and it often is, but certainly not always! Anybody who measures a speed increase of a factor 40 or more in comparison with native PowerShell commands, is probably incorrectly measuring or drawing an incorrect conclusion.

The point is that some .Net classes (like LINQ) using a lazy evaluation (also referred to as deferred execution⁽²⁾). Meaning that when assign an expression to a variable, it almost immediately appears to be done but in fact it didn't process anything yet!

Let presume that you dot-source your . .\Dosomething.ps1 command which has either a PowerShell or a more sophisticated Linq expression (for the ease of explanation, I have directly embedded the expressions directly into the Measure-Command):

$Data = @(1..100000).ForEach{[PSCustomObject]@{Index=$_;Property=(Get-Random)}}

(Measure-Command {
    $PowerShell = $Data.Where{$_.Index -eq 12345}
}).totalmilliseconds
864.5237

(Measure-Command {
    $Linq = [Linq.Enumerable]::Where($Data, [Func[object,bool]] { param($Item); Return $Item.Index -eq 12345})
}).totalmilliseconds
24.5949

The result appears obvious, the later Linq command is a about 40 times faster than the first PowerShell command. Unfortunately, it is not that simple...

Let's display the results:

PS C:\> $PowerShell

Index  Property
-----  --------
12345 104123841

PS C:\> $Linq

Index  Property
-----  --------
12345 104123841

As expected, the results are the same but if you have paid close attention, you will have noticed that it took a lot longer to display the $Linq results then the $PowerShell results.
Let's specifically measure that by just retrieving a property of the resulted object:

PS C:\> (Measure-Command {$PowerShell.Property}).totalmilliseconds
14.8798
PS C:\> (Measure-Command {$Linq.Property}).totalmilliseconds
1360.9435

It took about a factor 90 longer to retrieve a property of the $Linq object then the $PowerShell object and that was just a single object!

Also notice an other pitfall that if you do it again, certain steps might appear a lot faster then before, this is because some of the expressions have been cached.

Bottom line, if you want to compare the performance between two functions, you will need to implement them in your used case, start with a fresh PowerShell session and base your conclusion on the actual performance of the complete solution.

_{(1) For more background and examples on PowerShell and LINQ, I recommend tihis site: High Performance PowerShell with LINQ
(2) I think there is a minor difference between the two concepts as with lazy evaluation the result is calculated when needed as apposed to deferred execution were the result is calculated when the system is idle}

You could try the "Microsoft Date and Time Picker Control". To use it, in the Toolbox, you right-click and choose "Additional Controls...". Then you check "Microsoft Date and Time Picker Control 6.0" and OK. You will have a new control in the Toolbox to do what you need.

I just found some printscreen of this on : http://www.logicwurks.com/CodeExamplePages/EDatePickerControl.html Forget the procedures, just check the printscreens.

        this.name = name;
        this.species = Arrays.asList(speciesArr);
    }

    public void display() {
        System.out.println("Name: " + name);
        System.out.println("Elements in the List");
        System.out.println("********************");
        for (String string : species) {
            System.out.println(string);
        }
    }

OLD (pre v4):

Writing in es6 and using react 0.14.6 / react-router 2.0.0-rc5. I use this command to lookup the query params in my components:

this.props.location.query

It creates a hash of all available query params in the url.

UPDATE (React Router v4+):

this.props.location.query in React Router 4 has been removed (currently using v4.1.1) more about the issue here: https://github.com/ReactTraining/react-router/issues/4410

Looks like they want you to use your own method to parse the query params, currently using this library to fill the gap: https://github.com/sindresorhus/query-string

Try changing your Content Type (media type) to application/x-download and your Content-Disposition to: attachment;filename=" + fileName;

response.setContentType("application/x-download");
response.setHeader("Content-disposition", "attachment; filename=" + fileName);

Please change

con = (HttpURLConnection) new URL("http://localhost:8080/myapp/service/generate").openConnection();

To

con = (HttpURLConnection) new URL("http://YOUR_IP:8080/myapp/service/generate").openConnection();

There are 4 dimensions of the tensor you want to convert.

[:, ::-1, :, :] 

: means that the first dimension should be copied as it is and converted, same goes for the third and fourth dimension.

::-1 means that for the second axes it reverses the the axes

1. Check whether u have jdk installed in the path "C:\Program Files\Java" If not Install the JDK in your machine

2. In Eclipse, right click on "build.xml" then select Run As > External Tools Configuration

3. Click on "JRE" tab then click on "Installed JREs" > "ADD" > "Standard VM" > Click "Next

4. Select the Directory "C:\Program Files\Java\jdk1.7.x_xx" and the directory will be added to the "installed jres"

5. Select the new JDK directory and Click "OK"

6. Click on "Seperate JRE" dropdown and select the JDK version "jdk1.7.x_xx" and click on "Run"

This would help:)

There are two ways to do this:

CSS: Use width as %, like 75%, so the width of the div will change automatically when user resizes the browser.

Javascipt: Use resize event

$(window).bind('resize', function()
{
    if($(window).width() > 500)
        $('#divID').css('width', '300px');
    else
        $('divID').css('width', '200px');
});

Hope this will help you :)

From jQuery:

Set the date to highlight on first opening if the field is blank. Specify either an actual date via a Date object or as a string in the current dateFormat, or a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null for today.

Code examples

Initialize a datepicker with the defaultDate option specified.

$(".selector").datepicker({ defaultDate: +7 });

Get or set the defaultDate option, after init.

//getter
var defaultDate = $(".selector").datepicker("option", "defaultDate");
//setter
$(".selector").datepicker("option", "defaultDate", +7);

After the datepicker is intialized you should also be able to set the date with:

$(/*selector*/).datepicker("setDate" , date)

I had the same problem, tried setting path variables and everything. What SDK manager needs is not the JDK, but the actual Java SE end user crap. Go to http://www.java.com/en/download/ie_manual.jsp?locale=en and download that. As soon as I finished installing that, it worked like a charm

As it turns out, Git is smart enough not to drop a stash if it doesn't apply cleanly. I was able to get to the desired state with the following steps:

1. To unstage the merge conflicts: git reset HEAD . (note the trailing dot)
2. To save the conflicted merge (just in case): git stash
3. To return to master: git checkout master
4. To pull latest changes: git fetch upstream; git merge upstream/master
5. To correct my new branch: git checkout new-branch; git rebase master
6. To apply the correct stashed changes (now 2nd on the stack): git stash apply stash@{1}

Here is how to do that with the last version of HTTPClient (4.3.4)

    CloseableHttpClient httpclient = HttpClients.createDefault();
    try {
        HttpHost target = new HttpHost("localhost", 443, "https");
        HttpHost proxy = new HttpHost("127.0.0.1", 8080, "http");

        RequestConfig config = RequestConfig.custom()
                .setProxy(proxy)
                .build();
        HttpGet request = new HttpGet("/");
        request.setConfig(config);

        System.out.println("Executing request " + request.getRequestLine() + " to " + target + " via " + proxy);

        CloseableHttpResponse response = httpclient.execute(target, request);
        try {
            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());
            EntityUtils.consume(response.getEntity());
        } finally {
            response.close();
        }
    } finally {
        httpclient.close();
    }

Several ways to do it, this one's my favorite:

def number = '123' as int

In general, when you need a character that is "special" in regexes, just prefix it with a \. So a literal [ would be \[.

Try this:

$("input[type=checkbox]").prop('checked', true).uniform();
