Add the all tiles jars like(tiles-jsp,tiles-servlet,tiles-template,tiles-extras.tiles-core ) to your server lib folder and your application build path then it work if you using apache tailes with spring mvc application

This might have been mentioned in the above answers but not explicitly: with jagged array you can use array[row] to refer a whole row of data, but this is not allowed for multi-d arrays.

As far as I'm aware in order to format a date value you have to handle it in parameterMap,

$('#listDiv').kendoGrid({
            dataSource: {
                type: 'json',
                serverPaging: true,
                pageSize: 10,
                transport: {
                    read: {
                        url: '@Url.Action("_ListMy", "Placement")',
                        data: refreshGridParams,
                        type: 'POST'
                    },
                    parameterMap: function (options, operation) {
                        if (operation != "read") {
                            var d = new Date(options.StartDate);
                            options.StartDate = kendo.toString(new Date(d), "dd/MM/yyyy");
                            return options;
                        }
                        else { return options; }

                    }
                },
                schema: {
                    model: {
                        id: 'Id',
                        fields: {
                            Id: { type: 'number' },
                            StartDate: { type: 'date', format: 'dd/MM/yyyy' },
                            Area: { type: 'string' },
                            Length: { type: 'string' },
                            Display: { type: 'string' },
                            Status: { type: 'string' },
                            Edit: { type: 'string' }
                        }
                    },
                    data: "Data",
                    total: "Count"
                }
            },
            scrollable: false,
            columns:
                [
                    {
                        field: 'StartDate',
                        title: 'Start Date',
                        format: '{0:dd/MM/yyyy}',
                        width: 100
                    },

If you follow the above example and just renames objects like 'StartDate' then it should work (ignore 'data: refreshGridParams,')

ActiveModel::Dirty didn't work for me because the @model.update_attributes() hid the changes. So this is how I detected changes it in an update method in a controller:

def update
  @model = Model.find(params[:id])
  detect_changes

  if @model.update_attributes(params[:model])
    do_stuff if attr_changed?
  end
end

private

def detect_changes
  @changed = []
  @changed << :attr if @model.attr != params[:model][:attr]
end

def attr_changed?
  @changed.include :attr
end

If you're trying to detect a lot of attribute changes it could get messy though. Probably shouldn't do this in a controller, but meh.

In my case I made small changes, when i search the value in tabelview select (didSelectRowAtIndexPath) the cell its return the index of the cell so im get problem in move one viewControler to another.By using this method i found a solution to redirect to a new viewControler

let indexPath = tableView.indexPathForSelectedRow!
let currentCellValue = tableView.cellForRow(at: indexPath!)! as UITableViewCell
let textLabelText = currentCellValue.textLabel!.text
print(textLabelText)

Flex Solution

It is perfectly fine if you want to go with the display: table-cell solution. But instead of hacking it out, we have a better way to accomplish the same using display: flex;. flex is something which has a decent support.

.wrap {_x000D_
  height: 200px;_x000D_
  width: 200px;_x000D_
  border: 1px solid #aaa;_x000D_
  margin: 10px;_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
.wrap span {_x000D_
  align-self: flex-end;_x000D_
}

<div class="wrap">_x000D_
  <span>Align me to the bottom</span>_x000D_
</div>

In the above example, we first set the parent element to display: flex; and later, we use align-self to flex-end. This helps you push the item to the end of the flex parent.

Old Solution (Valid if you are not willing to use flex)

If you want to align the text to the bottom, you don't have to write so many properties for that, using display: table-cell; with vertical-align: bottom; is enough

div {_x000D_
  display: table-cell;_x000D_
  vertical-align: bottom;_x000D_
  border: 1px solid #f00;_x000D_
  height: 100px;_x000D_
  width: 100px;_x000D_
}

<div>Hello</div>

Radim Köhler's answer works, but here is a shorter version:

try by this

if(!Yii::$app->request->getIsPost()) 
{
  Yii::$app->response->redirect(array('user/index','id'=>302));
    exit(0);
}

First click show all files. Then in the bin folder choose any xml file and then right click and by selecting 'browse with' select your desired browser.

You try with the :before was pretty close, the only thing you had to change was actually using skew instead of the borders: http://jsfiddle.net/Hfkk7/1101/

Edit: Your border approach would work too, the only thing you did wrong was having the before element on top of your div, so the transparent border wasnt showing. If you would have position the pseudo element to the left of your div, everything would have worked too: http://jsfiddle.net/Hfkk7/1102/

Assuming you're referring to this plugin, your code should be:

// To Store
$(function() {
    $.session.set("myVar", "value");
});


// To Read
$(function() {
    alert($.session.get("myVar"));
});

Before using a plugin, remember to read its documentation in order to learn how to use it. In this case, an usage example can be found in the README.markdown file, which is displayed on the project page.

this seems to be an ASPX pages problem, I have never been able to show a favicon in any page for IE (all others yes Chrome, FF and safari) the only sites that I've seen that are the exception to that rule are bing.com, msdn.com and others that belong to MS and run on asp.net, there is something that they are not telling us! even world-known sites cant show in IE eg: manu.com (most browsed sports team in the world) aspx site and fails to dislplay the favicon on IE. http://www.manutd.com/favicon.ico does show the icon.

Please prove me wrong.

To compare values you can use a comparing method-

function naturalSorter(as, bs){
    var a, b, a1, b1, i= 0, n, L,
    rx=/(\.\d+)|(\d+(\.\d+)?)|([^\d.]+)|(\.\D+)|(\.$)/g;
    if(as=== bs) return 0;
    a= as.toLowerCase().match(rx);
    b= bs.toLowerCase().match(rx);
    L= a.length;
    while(i<L){
        if(!b[i]) return 1;
        a1= a[i],
        b1= b[i++];
        if(a1!== b1){
            n= a1-b1;
            if(!isNaN(n)) return n;
            return a1>b1? 1:-1;
        }
    }
    return b[i]? -1:0;
}

But for speed in sorting an array, rig the array before sorting, so you only have to do lower case conversions and the regular expression once instead of in every step through the sort.

function naturalSort(ar, index){
    var L= ar.length, i, who, next, 
    isi= typeof index== 'number', 
    rx=  /(\.\d+)|(\d+(\.\d+)?)|([^\d.]+)|(\.(\D+|$))/g;
    function nSort(aa, bb){
        var a= aa[0], b= bb[0], a1, b1, i= 0, n, L= a.length;
        while(i<L){
            if(!b[i]) return 1;
            a1= a[i];
            b1= b[i++];
            if(a1!== b1){
                n= a1-b1;
                if(!isNaN(n)) return n;
                return a1>b1? 1: -1;
            }
        }
        return b[i]!= undefined? -1: 0;
    }
    for(i= 0; i<L; i++){
        who= ar[i];
        next= isi? ar[i][index] || '': who;
        ar[i]= [String(next).toLowerCase().match(rx), who];
    }
    ar.sort(nSort);
    for(i= 0; i<L; i++){
        ar[i]= ar[i][1];
    }
}

Try this.

public class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        var json = config.Formatters.JsonFormatter;
        json.SupportedMediaTypes.Add(new System.Net.Http.Headers.MediaTypeHeaderValue("application/json"));
        config.Formatters.Remove(config.Formatters.XmlFormatter);

        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional , Action =RouteParameter.Optional }

        );
    }
}

Firebug shows this correctly because your Browser automagically fixes the bad markup for you. This behaviour is not specified anywhere and can (will) vary from browser to browser. Those tags are required by the DOCTYPE you're using and should not be omitted.

The html element is the root element of every html page. If you look at all other elements' description it says where an element can be used (and almost all elements require either head or body).

The problem is not in your Spring annotations but your design pattern. You mix together different scopes and threads:

• singleton
• session (or request)
• thread pool of jobs

The singleton is available anywhere, it is ok. However session/request scope is not available outside a thread that is attached to a request.

Asynchronous job can run even the request or session doesn't exist anymore, so it is not possible to use a request/session dependent bean. Also there is no way to know, if your are running a job in a separate thread, which thread is the originator request (it means aop:proxy is not helpful in this case).

I think your code looks like that you want to make a contract between ReportController, ReportBuilder, UselessTask and ReportPage. Is there a way to use just a simple class (POJO) to store data from UselessTask and read it in ReportController or ReportPage and do not use ReportBuilder anymore?

You need to write a controller with ng-change function in scope. In ng-change callback you do a call to server and update completions. Here is a stub (without $http as this is a plunk):

HTML

<!doctype html>
<html ng-app="plunker">
    <head>
        <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.js"></script>
        <script src="http://angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.4.0.js"></script>
        <script src="example.js"></script>
        <link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.1/css/bootstrap-combined.min.css" rel="stylesheet">
    </head>
    <body>
        <div class='container-fluid' ng-controller="TypeaheadCtrl">
            <pre>Model: {{selected| json}}</pre>
            <pre>{{states}}</pre>
            <input type="text" ng-change="onedit()" ng-model="selected" typeahead="state for state in states | filter:$viewValue">
        </div>
    </body>
</html>

JS

angular.module('plunker', ['ui.bootstrap']);

function TypeaheadCtrl($scope) {
  $scope.selected = undefined;
  $scope.states = [];

  $scope.onedit = function(){
    $scope.states = [];

    for(var i = 0; i < Math.floor((Math.random()*10)+1); i++){
      var value = "";

      for(var j = 0; j < i; j++){
        value += j;
      }
      $scope.states.push(value);
    }
  }
}

 $(function(){
            $(document).find('div').siblings().each(function(){
                var obj = $(this);
                obj.find('div').each(function(){
                    var obj1 = $(this);
                    if(!obj1.children().length > 0){
                        alert(obj1.html());
                    }
                });

            });
        });

<div id="2">
    <div>
        <div>
            <div>XYZ Pvt. Ltd.</div>
        </div>
    </div>
</div>
<div id="3">
    <div>
        <div>
            <div>ABC Pvt Ltd.</div>
        </div>
    </div>
</div>

Yes, this is described in the documentation. You have to use the InOrder class.

Example (assuming two mocks already created):

InOrder inOrder = inOrder(serviceAMock, serviceBMock);

inOrder.verify(serviceAMock).methodOne();
inOrder.verify(serviceBMock).methodTwo();

I don't know of any direct answer as how to find exactly what process is using the swap space, however, this link may be helpful. Another good one is over here

Also, use a good tool like htop to see which processes are using a lot of memory and how much swap overall is being used.

You can also use @font-face to link to the URLs. http://www.css3.info/preview/web-fonts-with-font-face/

Does the CMS support iframes? You might be able to throw an iframe into the top of your content, too. This would probably be slower - better to include it in your CSS.

Select * from Table1 t1 Left Join Table2 t2 on t1.id=t2.id By definition: Left Join selects all columns mentioned with the "select" keyword from Table 1 and the columns from Table 2 which matches the criteria after the "on" keyword.

Similarly,By definition: Right Join selects all columns mentioned with the "select" keyword from Table 2 and the columns from Table 1 which matches the criteria after the "on" keyword.

Referring to your question, id's in both the tables are compared with all the columns needed to be thrown in the output. So, ids 1 and 2 are common in the both the tables and as a result in the result you will have four columns with id and name columns from first and second tables in order.

*select * from Table1 left join Table2 on Table1.id = Table2.id

The above expression,it takes all the records (rows) from table 1 and columns, with matching id's from table 1 and table 2, from table 2.

select * from Table2 right join Table1 on Table1.id = Table2.id**

Similarly from the above expression,it takes all the records (rows) from table 1 and columns, with matching id's from table 1 and table 2, from table 2. (remember, this is a right join so all the columns from table2 and not from table1 will be considered).

The problem is when you split your command over multiple lines. So, you can either use the \ at the end of lines for continuation as above or you can get everything on one line with the && operator in bash.

Then you can use a test command to test if the file does exist, e.g.:

test -f myApp && echo File does exist

-f file True if file exists and is a regular file.

-s file True if file exists and has a size greater than zero.

or does not:

test -f myApp || echo File does not exist
test ! -f myApp && echo File does not exist

The test is equivalent to [ command.

[ -f myApp ] && rm myApp   # remove myApp if it exists

and it would work as in your original example.

See: help [ or help test for further syntax.

>>> a = 147.234
>>> a % 1
0.23400000000000887
>>> a // 1
147.0
>>>

If you want the integer part as an integer and not a float, use int(a//1) instead. To obtain the tuple in a single passage: (int(a//1), a%1)

EDIT: Remember that the decimal part of a float number is approximate, so if you want to represent it as a human would do, you need to use the decimal library

Swift Style:

UISegmentedControl.appearance().setTitleTextAttributes(NSDictionary(objects: [UIFont.systemFontOfSize(14.0)], forKeys: [NSFontAttributeName]), forState: UIControlState.Normal)

WARNING: Long script ahead.

A while ago, I faced a similar problem: from a Tcl script, launch a number of processes, then wait for all of them to finish. Here is a demo script I wrote to solve this problem.

main.tcl

#!/usr/bin/env tclsh

# Launches many processes and wait for them to finish.
# This script will works on systems that has the ps command such as
# BSD, Linux, and OS X

package require Tclx; # For process-management utilities

proc updatePidList {stat} {
    global pidList
    global allFinished

    # Parse the process ID of the just-finished process
    lassign $stat processId howProcessEnded exitCode

    # Remove this process ID from the list of process IDs
    set pidList [lindex [intersect3 $pidList $processId] 0]
    set processCount [llength $pidList]

    # Occasionally, a child process quits but the signal was lost. This
    # block of code will go through the list of remaining process IDs
    # and remove those that has finished
    set updatedPidList {}
    foreach pid $pidList {
        if {![catch {exec ps $pid} errmsg]} {
            lappend updatedPidList $pid
        }
    }

    set pidList $updatedPidList

    # Show the remaining processes
    if {$processCount > 0} {
        puts "Waiting for [llength $pidList] processes"
    } else {
        set allFinished 1
        puts "All finished"
    }
}

# A signal handler that gets called when a child process finished.
# This handler needs to exit quickly, so it delegates the real works to
# the proc updatePidList

yo where wrong! To this theme i wrote an question to oracle. The answer was.

"If you compile your code on an 32 Bit Machine, your code should only run on an 32 Bit Processor. If you want to run your code on an 64 Bit JVM you have to compile your class Files on an 64 Bit Machine using an 64-Bit JDK."

Wrap your Promise inside a function or it will start to do its job right away. Plus, you can pass parameters to the function:

var some_function = function(username, password)
{
 return new Promise(function(resolve, reject)
 {
  /*stuff using username, password*/
  if ( /* everything turned out fine */ )
  {
   resolve("Stuff worked!");
  }
  else
  {
   reject(Error("It broke"));
  }
 });
}

Then, use it:

some_module.some_function(username, password).then(function(uid)
{
 // stuff
})

ES6:

const some_function = (username, password) =>
{
 return new Promise((resolve, reject) =>
 {
  /*stuff using username, password*/

  if ( /* everything turned out fine */ )
  {
   resolve("Stuff worked!");
  }
  else
  {
   reject(Error("It broke"));
  }
 });
};

Use:

some_module.some_function(username, password).then(uid =>
{
 // stuff
});

On Windows you can try these steps:

1. Download a root CA certificate from the website.
2. Find a file jssecacerts in the directory /lib/security with JRE (you can use a comand System.out.println(System.getProperty("java.home"); to find the folder with the current JRE). Make a backup of the file.
3. Download a program portecle.
4. Open the jssecacerts file in portecle.
5. Enter the password: changeit.
6. Import the downloaded certificate with porticle (Tools > Import Trusted Certificate).
7. Click Save.
8. Replace the original file jssecacerts.

The mysql client is available in macOS ports. If you don't have this excellent third party package manager already installed, it is available from here: https://www.macports.org/

Once you have installed macports, open a terminal and make sure everything is up to date:

sudo port selfupdate

There are multiple different versions of MySQL and mariadb (community fork of MySQL) available in the ports repos. List available versions using the following command:

port search 'mariadb*'

I recommend choosing mariadb over mysql as it is, mostly, a drop in replacement (https://mariadb.com/kb/en/mariadb-vs-mysql-compatibility/) and has excellent community support.

If applicable, choose which version of mariadb you want (a list of versions of mariadb is available here: https://downloads.mariadb.org/mariadb/+releases/). If you're not bothered, install the default version:

sudo port install mariadb

Mariadb (including the mysql-compatible command line client) is now available on your system. On my system, the CLI client resides in the following location:

$ /opt/local/bin/mysql --version
/opt/local/bin/mysql  Ver 15.1 Distrib 5.5.68-MariaDB, for osx10.15 (x86_64) using readline 5.1

It's obviously a bit inconvenient to type out the full path, /opt/local/bin/mysql each time you want to use the client. Ports has already thought of this problem. To view available versions of mysql on your system, run:

$ port select mysql

Available versions for mysql:
mariadb (active)
none

Choose one from the list. For example, to use mariadb as the default mysql client:

sudo port select mysql mariadb

Now open a fresh terminal window and you should be able to start the mariadb mysql CLI client:

mysql -h <hostname> -u <username> -p

use this code in the file application.properties:

#Enable logging for config troubeshooting
logging.level.org.hibernate.SQL=DEBUG
logging.level.com.zaxxer.hikari.HikariConfig=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE

You code is ok only except that you can't add same class test1.

$('.page-address-edit').addClass('test1').addClass('test2'); //this will add test1 and test2

And you could also do

$('.page-address-edit').addClass('test1 test2');

but it ONLY shows the index.html file and NOTHING attached to it, so no images, no effects or anything that the html file should display.

That's because in your program that's the only thing that you return to the browser regardless of what the request looks like.

You can take a look at a more complete example that will return the correct files for the most common web pages (HTML, JPG, CSS, JS) in here https://gist.github.com/hectorcorrea/2573391

Also, take a look at this blog post that I wrote on how to get started with node. I think it might clarify a few things for you: http://hectorcorrea.com/blog/introduction-to-node-js

this is what worked for me,

sudo -H pip install flask

Or for pip3(python3) use :

sudo -H pip3 install flask

Sidenote

If you're using virtualenv it's a good idea to pip freeze >> requirements.txt to allow for the installed packages to be listed in one place. The sudo command and -H flag. For more on sudo's -H flag, look at Paul's answer. Hope this helps you.

I used AutoIt to do it.

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

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

Using @angular/forms when you use a <form> tag it automatically creates a FormGroup.

For every contained ngModel tagged <input> it will create a FormControl and add it into the FormGroup created above; this FormControl will be named into the FormGroup using attribute name.

Example:

<form #f="ngForm">
    <input type="text" [(ngModel)]="firstFieldVariable" name="firstField">
    <span>{{ f.controls['firstField']?.value }}</span>
</form>

Said this, the answer to your question follows.

When you mark it as standalone: true this will not happen (it will not be added to the FormGroup).

Reference: https://github.com/angular/angular/issues/9230#issuecomment-228116474

For IE: window.close(); and self.close(); should work fine.

If you want just open the IE browser and type

javascript:self.close() and hit enter, it should ask you for a prompt.

Note: this method doesn't work for Chrome or Firefox.

Follow the steps given below as I also had the same problem:

$ git pull origin master --allow-unrelated-histories 

(To see if local branch can be easily merged with remote one)

$ git push -u origin master 

(Now push entire content of local git repository to your online repository)

I think you need to use Expr with ->set() (However THIS IS NOT SAFE and you shouldn't do it):

$qb = $this->em->createQueryBuilder();
$q = $qb->update('models\User', 'u')
        ->set('u.username', $qb->expr()->literal($username))
        ->set('u.email', $qb->expr()->literal($email))
        ->where('u.id = ?1')
        ->setParameter(1, $editId)
        ->getQuery();
$p = $q->execute();

It's much safer to make all your values parameters instead:

$qb = $this->em->createQueryBuilder();
$q = $qb->update('models\User', 'u')
        ->set('u.username', '?1')
        ->set('u.email', '?2')
        ->where('u.id = ?3')
        ->setParameter(1, $username)
        ->setParameter(2, $email)
        ->setParameter(3, $editId)
        ->getQuery();
$p = $q->execute();

This answer extends on Jayson's excellent answer with some more opinionated guidance on the best approach for your use case:

• SDKMAN is the best solution for most users. It's easy to use, doesn't have any weird configuration, and makes managing multiple versions for lots of other Java ecosystem projects easy as well.
• Downloading Java versions via Homebrew and switching versions via jenv is a good option, but requires more work. For example, the Homebrew commands in this highly upvoted answer don't work anymore. jenv is slightly harder to setup, the plugins aren't well documented, and the README says the project is looking for a new maintainer. jenv is still a great project, solves the job, and the community should be thankful for the wonderful contribution. SDKMAN is just the better option cause it's so great.
• Jabba is written is a multi-platform solution that provides the same interface on Mac, Windows, and PC (it's written in Go and that's what allows it to be multiplatform). If you care about a multiplatform solution, this is a huge selling point. If you only care about running multiple versions on your Mac, then you don't need a multiplatform solution. SDKMAN's support for tens of popular SDKs is what you're missing out on if you go with Jabba.

Managing versions manually is probably the worst option. If you decide to manually switch versions, you can use this Bash code instead of Jayson's verbose code (code snippet from the homebrew-openjdk README:

jdk() {
        version=$1
        export JAVA_HOME=$(/usr/libexec/java_home -v"$version");
        java -version
 }

Jayson's answer provides the basic commands for SDKMAN and jenv. Here's more info on SDKMAN and more info on jenv if you'd like more background on these tools.

you have to rename each column

SELECT col1 as MyCol1,
       col2 as MyCol2,
 .......
 FROM `foobar`

Clear:both gives you that space between them.

For example your code:

  <div style="float:left">Hello</div>
  <div style="float:right">Howdy dere pardner</div>

Will currently display as :

Hello  ...................   Howdy dere pardner

If you add the following to above snippet,

  <div style="clear:both"></div>

In between them it will display as:

Hello ................ 
                       Howdy dere pardner

giving you that space between hello and Howdy dere pardner.

If you need to redirect out of your angular application use $window.location. That was my case; hopefully someone will find it useful.

Use a Spannable String

 String s= "Hello Everyone";
 SpannableString ss1=  new SpannableString(s);
 ss1.setSpan(new RelativeSizeSpan(2f), 0,5, 0); // set size
 ss1.setSpan(new ForegroundColorSpan(Color.RED), 0, 5, 0);// set color
 TextView tv= (TextView) findViewById(R.id.textview);
 tv.setText(ss1); 

Snap shot

You can split string using space and add span to the string you require.

 String s= "Hello Everyone";  
 String[] each = s.split(" ");

Now apply span to the string and add the same to textview.

Also the error can be solved by adding several flags, like -marm -mthumb-interwork. It was helpful for me to avoid this same error.

import java.util.Scanner;

public class SumAll {
    public static void sumAll(int arr[]) {//initialize method return sum
        int sum = 0;
        for (int i = 0; i < arr.length; i++) {
            sum += arr[i];
        }
        System.out.println("Sum is : " + sum);
    }

    public static void main(String[] args) {
        int num;
        Scanner input = new Scanner(System.in);//create scanner object 
        System.out.print("How many # you want to add : ");
        num = input.nextInt();//return num from keyboard
        int[] arr2 = new int[num];
        for (int i = 0; i < arr2.length; i++) {
            System.out.print("Enter Num" + (i + 1) + ": ");
            arr2[i] = input.nextInt();
        }
        sumAll(arr2);
    }

Drawable d = getResources().getDrawable(android.R.drawable.ic_dialog_email);
ImageView image = (ImageView)findViewById(R.id.image);
image.setImageDrawable(d);

Running .NET core (3.1.4) on IIS behind a Load balancer did not work with other suggested solutions.

Manually reading the X-Forwarded-For header does.

IPAddress ip;
var headers = Request.Headers.ToList();
if (headers.Exists((kvp) => kvp.Key == "X-Forwarded-For"))
{
    // when running behind a load balancer you can expect this header
    var header = headers.First((kvp) => kvp.Key == "X-Forwarded-For").Value.ToString();
    ip = IPAddress.Parse(header);
}
else
{
    // this will always have a value (running locally in development won't have the header)
    ip = Request.HttpContext.Connection.RemoteIpAddress;
}

Currently, there is no C# class that correctly handles ISO 8601week numbers. Even though you can instantiate a culture, look for the closest thing and correct that, I think it is better to do the complete calculation yourself:

    /// <summary>
    /// Converts a date to a week number.
    /// ISO 8601 week 1 is the week that contains the first Thursday that year.
    /// </summary>
    public static int ToIso8601Weeknumber(this DateTime date)
    {
        var thursday = date.AddDays(3 - date.DayOfWeek.DayOffset());
        return (thursday.DayOfYear - 1) / 7 + 1;
    }

    /// <summary>
    /// Converts a week number to a date.
    /// Note: Week 1 of a year may start in the previous year.
    /// ISO 8601 week 1 is the week that contains the first Thursday that year, so
    /// if December 28 is a Monday, December 31 is a Thursday,
    /// and week 1 starts January 4.
    /// If December 28 is a later day in the week, week 1 starts earlier.
    /// If December 28 is a Sunday, it is in the same week as Thursday January 1.
    /// </summary>
    public static DateTime FromIso8601Weeknumber(int weekNumber, int? year = null, DayOfWeek day = DayOfWeek.Monday)
    {
        var dec28 = new DateTime((year ?? DateTime.Today.Year) - 1, 12, 28);
        var monday = dec28.AddDays(7 * weekNumber - dec28.DayOfWeek.DayOffset());
        return monday.AddDays(day.DayOffset());
    }

    /// <summary>
    /// Iso8601 weeks start on Monday. This returns 0 for Monday.
    /// </summary>
    private static int DayOffset(this DayOfWeek weekDay)
    {
        return ((int)weekDay + 6) % 7;
    }

Well after a little more googling and reading I found this:

bool[] bPrimes = new bool[1000000];
bPrimes = Array.ConvertAll<bool, bool>(bPrimes, b=> b=true);

Which is certainly closer to what I'm looking for. But I'm not sure if that's better than iterating through the original array in a for-loop and just changing the values. After a quick test in fact, it appears slower by about a factor of 5. So not really a good solution then!

My final solution

class DynamicModeTabLayout : TabLayout {

    constructor(context: Context?) : super(context)
    constructor(context: Context?, attrs: AttributeSet?) : super(context, attrs)
    constructor(context: Context?, attrs: AttributeSet?, defStyleAttr: Int) : super(context, attrs, defStyleAttr)

    override fun setupWithViewPager(viewPager: ViewPager?) {
        super.setupWithViewPager(viewPager)

        val view = getChildAt(0) ?: return
        view.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED)
        val size = view.measuredWidth

        if (size > measuredWidth) {
            tabMode = MODE_SCROLLABLE
            tabGravity = GRAVITY_CENTER
        } else {
            tabMode = MODE_FIXED
            tabGravity = GRAVITY_FILL
        }
    }
}

You should not used document.getElementByID because its work only for client side controls which ids are fixed . You should use jquery instead like below example.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>                                                                                                             
<div id="foo">
   <div class="bar"> 
          Hello world!
     </div>
</div>

use this :

$("[id^='foo']").find("[class^='bar']")

// do not forget to add script tags as above

if you want any remove edit any operation then just add "." behind and do the operations

Try this following program for 2d array in java:

public class ArrayTwo2 {
    public static void main(String[] args) throws  IOException,NumberFormatException{
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        int[][] a;
        int sum=0;
        a=new int[3][2];
        System.out.println("Enter array with 5 elements");
        for(int i=0;i<a.length;i++)
        {
            for(int j=0;j<a[0].length;j++)
            {
            a[i][j]=Integer.parseInt(br.readLine());
            }
        }
        for(int i=0;i<a.length;i++)
        {
            for(int j=0;j<a[0].length;j++)
            {
            System.out.print(a[i][j]+"  ");
            sum=sum+a[i][j];
            }
        System.out.println();   
        //System.out.println("Array Sum: "+sum);
        sum=0;
        }
    }
}

Have you checked in console if data from form is properly serialized? Is ajax request successful? Also you didn't close placeholder quote in, which can cause some problems:

 <textarea name="comentarii" cols="36" rows="5" placeholder="Message>  

If you pass the name of an array as an argument to a function, it is treated as if you had passed the address of the array. So &s and s are identical arguments. See K&R 5.3. &s[0] is the same as &s, since it takes the address of the first element of the array, which is the same as taking the address of the array itself.

For all the others, although all pointers are essentially memory locations they are still typed, and the compiler will warn about assigning one type of pointer to another.

• void* p; says p is a memory address, but I don't know what's in the memory
• char* s; says s is a memory address, and the first byte contains a character
• char** ps; says ps is a memory address, and the four bytes there (for a 32-bit system) contain a pointer of type char*.

Since --with-ssl is not recognized anymore I just installed the libssl-dev. For debian based systems:

sudo apt-get install libssl-dev 

For CentOS and RHEL

sudo yum install openssl-devel

To restart the make first clean up by:

make clean

Then start again and execute the following commands one after the other:

./configure
make
make test
make install

Reading a file in and by itself takes some time, garbage collecting the result is another problem as you read the whole file just to count the newline character(s),

At some point, someone is going to have to read the characters in the file, regardless if this the framework or if it is your code. This means you have to open the file and read it into memory if the file is large this is going to potentially be a problem as the memory needs to be garbage collected.

Nima Ara made a nice analysis that you might take into consideration

Here is the solution proposed, as it reads 4 characters at a time, counts the line feed character and re-uses the same memory address again for the next character comparison.

private const char CR = '\r';  
private const char LF = '\n';  
private const char NULL = (char)0;

public static long CountLinesMaybe(Stream stream)  
{
    Ensure.NotNull(stream, nameof(stream));

    var lineCount = 0L;

    var byteBuffer = new byte[1024 * 1024];
    const int BytesAtTheTime = 4;
    var detectedEOL = NULL;
    var currentChar = NULL;

    int bytesRead;
    while ((bytesRead = stream.Read(byteBuffer, 0, byteBuffer.Length)) > 0)
    {
        var i = 0;
        for (; i <= bytesRead - BytesAtTheTime; i += BytesAtTheTime)
        {
            currentChar = (char)byteBuffer[i];

            if (detectedEOL != NULL)
            {
                if (currentChar == detectedEOL) { lineCount++; }

                currentChar = (char)byteBuffer[i + 1];
                if (currentChar == detectedEOL) { lineCount++; }

                currentChar = (char)byteBuffer[i + 2];
                if (currentChar == detectedEOL) { lineCount++; }

                currentChar = (char)byteBuffer[i + 3];
                if (currentChar == detectedEOL) { lineCount++; }
            }
            else
            {
                if (currentChar == LF || currentChar == CR)
                {
                    detectedEOL = currentChar;
                    lineCount++;
                }
                i -= BytesAtTheTime - 1;
            }
        }

        for (; i < bytesRead; i++)
        {
            currentChar = (char)byteBuffer[i];

            if (detectedEOL != NULL)
            {
                if (currentChar == detectedEOL) { lineCount++; }
            }
            else
            {
                if (currentChar == LF || currentChar == CR)
                {
                    detectedEOL = currentChar;
                    lineCount++;
                }
            }
        }
    }

    if (currentChar != LF && currentChar != CR && currentChar != NULL)
    {
        lineCount++;
    }
    return lineCount;
}

Above you can see that a line is read one character at a time as well by the underlying framework as you need to read all characters to see the line feed.

If you profile it as done bay Nima you would see that this is a rather fast and efficient way of doing this.

Yes, here you can use LIMIT.

You can try it by the below query:

SELECT * FROM employee_list SORT BY salary DESC LIMIT 2

The settings file is never created automatically, you must create it yourself, whether you use embedded or "real" maven.

Create it at the following location <your home folder>/.m2/settings.xml e.g. C:\Users\YourUserName\.m2\settings.xml on Windows or /home/YourUserName/.m2/settings.xml on Linux

Here's an empty skeleton you can use:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository/>
  <interactiveMode/>
  <usePluginRegistry/>
  <offline/>
  <pluginGroups/>
  <servers/>
  <mirrors/>
  <proxies/>
  <profiles/>
  <activeProfiles/>
</settings>

If you use Eclipse to edit it, it will give you auto-completion when editing it.

And here's the Maven settings.xml Reference page

You have it reversed. The 100 should be the first parameter (it's the key) and the "one" should be the second parameter (it's the value).

Read the javadoc for HashMap and that might help you: HashMap

To get the value, use hashmap.get(100).

In Visual Studio:

1. project properties (right click on your project)
2. Debug -> Start Options
3. Make sure "Command line arguments" is empty

when click on div alert key

   $(document).delegate(".searchbtn", "click", function() {
        var key=$.trim($('#txtkey').val());
        alert(key);
        });

Here is what I found for Google Sheets:

To get the current sheet name in Google sheets, the following simple script can help you without entering the name manually, please do as this:

1. Click Tools > Script editor

2. In the opened project window, copy and paste the below script code into the blank Code window, see screenshot:

......................

function sheetName() {
  return SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getName();
}

Then save the code window, and go back to the sheet that you want to get its name, then enter this formula: =sheetName() in a cell, and press Enter key, the sheet name will be displayed at once.

See this link with added screenshots: https://www.extendoffice.com/documents/excel/5222-google-sheets-get-list-of-sheets.html

If you just want the milliseconds since 01-JAN-1970, then you can use

var theMoment = moment(); // or whatever your moment instance is
var millis;

millis = +theMoment; // a short but not very readable form
// or
millis = theMoment.valueOf();
// or (almost sure not as efficient as above)
millis = theMoment.toDate().getTime();

To use shorthand to get the direction:

int direction = column == 0
                ? 0
                : (column == _gridSize - 1 ? 1 : rand.Next(2));

To simplify the code entirely:

if (column == gridSize - 1 || rand.Next(2) == 1)
{
}
else
{
}

Today I was trying same in db2 and used below, in my case I had spaces at the end of varchar column data

SELECT EmployeeName FROM EmployeeTable WHERE LENGTH(TRIM(EmployeeName))> 4;

I have your answer, as I just had the same problem today:

Someone made a working vba code that changes the vba protection password to "macro", for all excel files, including .xlsm (2007+ versions). You can see how it works by browsing his code.

This is the guy's blog: http://lbeliarl.blogspot.com/2014/03/excel-removing-password-from-vba.html Here's the file that does the work: https://docs.google.com/file/d/0B6sFi5sSqEKbLUIwUTVhY3lWZE0/edit

Pasted from a previous post from his blog:

For Excel 2007/2010 (.xlsm) files do following steps:

1. Create a new .xlsm file.
2. In the VBA part, set a simple password (for instance 'macro').
3. Save the file and exit.
4. Change file extention to '.zip', open it by any archiver program.
5. Find the file: 'vbaProject.bin' (in 'xl' folder).
6. Extract it from archive.
7. Open the file you just extracted with a hex editor.

8. Find and copy the value from parameter DPB (value in quotation mark), example: DPB="282A84CBA1CBA1345FCCB154E20721DE77F7D2378D0EAC90427A22021A46E9CE6F17188A". (This value generated for 'macro' password. You can use this DPB value to skip steps 1-8)

9. Do steps 4-7 for file with unknown password (file you want to unlock).

10. Change DBP value in this file on value that you have copied in step 8.

    If copied value is shorter than in encrypted file you should populate missing characters with 0 (zero). If value is longer - that is not a problem (paste it as is).

11. Save the 'vbaProject.bin' file and exit from hex editor.

12. Replace existing 'vbaProject.bin' file with modified one.
13. Change extention from '.zip' back to '.xlsm'
14. Now, open the excel file you need to see the VBA code in. The password for the VBA code will simply be macro (as in the example I'm showing here).

I noticed this wasn't working with a static-first-then-reverse-proxy setup. Here's what that looks like:

location @app {
  proxy_pass http://localhost:3000$request_uri;
}

location / {
  try_files $uri $uri/ @app;
  error_page 405 @app;
}

MSDN is actually pretty clear on this one.

• Console.Read: Reads the next character from the standard input stream.
• Console.ReadLine: Reads the next line of characters from the standard input stream.

I love this question! You could easily adapt my code below to be a white × on an orange square:

From the EJB3.0 Specification:

Use of the cascade annotation element may be used to propagate the effect of an operation to associated entities. The cascade functionality is most typically used in parent-child relationships.

If X is a managed entity, the remove operation causes it to become removed. The remove operation is cascaded to entities referenced by X, if the relationships from X to these other entities is annotated with the cascade=REMOVE or cascade=ALL annotation element value.

So in a nutshell, entity relationships defined with CascadeType.All will ensure that all persistence events such as persist, refresh, merge and remove that occur on the parent, will be passed to the child. Defining other CascadeType options provides the developer with a more granular level of control over how the entity association handles persistence.

For example if I had an object Book that contained a List of pages and I add a page object within this list. If the @OneToMany annotation defining the association between Book and Page is marked as CascadeType.All, persisting the Book would result in the Page also being persisted to the database.

New Way

Starting with Go 1.16, use os.ReadFile to load the file to memory, use os.WriteFile to write to a file from memory.

Be careful with the os.ReadFile because it reads the whole file into memory.

package main

import "os"

func main() {
    b, err := os.ReadFile("input.txt")
    if err != nil {
        log.Fatal(err)
    }

    // `data` contains everything your file does
    // This writes it to the Standard Out
    os.Stdout.Write(data)

    // You can also write it to a file as a whole
    err = os.WriteFile("destination.txt", b, 0644)
    if err != nil {
        log.Fatal(err)
    }
}

I was getting the same error message but had a different issue. Posting for others that are stuck on same.

I ported the get, post, put, delete functions to new router file while refactoring, and forgot to edit the paths. Example:

Incorrect:

//server.js
app.use('/blog-posts', blogPostsRouter);

//routers/blogPostsRouter.js
router.get('/blog-posts', (req, res) => {
  res.json(BlogPosts.get());
});

Correct:

//server.js
app.use('/blog-posts', blogPostsRouter);

//routers/blogPostsRouter.js
router.get('/', (req, res) => {
  res.json(BlogPosts.get());
});

Took a while to spot, as the error had me checking syntax where I might have been wrapping an argument in an object or where I missed the module.exports = router;

I need to add my 5 cents. I see everybody use [ or [[, but it worth to mention that they are not part of if syntax.

For arithmetic comparisons, use ((...)) instead.

((...)) is an arithmetic command, which returns an exit status of 0 if the expression is nonzero, or 1 if the expression is zero. Also used as a synonym for "let", if side effects (assignments) are needed.

See: ArithmeticExpression

I know this question was specific to JavaScript, however, there seems to be no good, clean way to ALWAYS detect when a textarea changes in all current browsers. I've learned jquery has taken care of it for us. It even handles contextual menu changes to text areas. The same syntax is used regardless of input type.

    $('div.lawyerList').on('change','textarea',function(){
      // Change occurred so count chars...
    });

or

    $('textarea').on('change',function(){
      // Change occurred so count chars...
    });

For Ionic (Typescript) you have to double slash in order to scape the characters. For example (this is to match some special characters):

"^(?=.*[\\]\\[!¡\'=ªº\\-\\_ç@#$%^&*(),;\\.?\":{}|<>\+\\/])"

Pay attention to this ] [ - _ . / characters. They have to be double slashed. If you don't do that, you are going to have a type error in your code.

Primary key -> Any column or set of columns that can uniquely identify a record in the table is a primary key. (There can be only one Primary key in the table) and the candidate key-> the same as Primary key but the Primary Key chosen by DB administrator's prospective for example(the primary key the least candidate key in size)

JavaScript normally convert local timezone to UTC .

date = new Date();
date.setMinutes(date.getMinutes()-date.getTimezoneOffset())
JSON.stringify(date)

The correct statement should be :

SELECT
  student.firstname,
  student.lastname,
  exam.name,
  exam.date,
  grade.grade
FROM grade
  INNER JOIN student
    ON student.studentId = grade.fk_studentId
  INNER JOIN exam
    ON exam.examId = grade.fk_examId
ORDER BY exam.date

A table is refered to other on the basis of the foreign key relationship defined. You should refer the ids properly if you wish the data to show as queried. So you should refer the id's to the proper foreign keys in the table rather than just on the id which doesn't define a proper relation

You must group both columns, group and sub-group, then use the aggregate function COUNT().

SELECT
  group, subgroup, COUNT(*)
FROM
  groups
GROUP BY
  group, subgroup

i usually use ng-show

<li ng-show="variable.length"></li>

where variable you define for example

<div class="list-group-item" ng-repeat="product in store.products">
   <li ng-show="product.length">show something</li>
</div>

How to disable strict mode in MySQL 5.7:

Edit file /etc/mysql/mysql.conf.d/mysqld.cnf

If below line exists in mysql.cnf

sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Then Replace it with

sql_mode='MYSQL40'

Otherwise

Just add below line in mysqld.cnf

sql_mode='MYSQL40'

This resolved problem.

Here are another 2 options that allow you to invoke SaveChanges() in a for each loop.

The first option is use one DBContext to generate your list objects to iterate through, and then create a 2nd DBContext to call SaveChanges() on. Here is an example:

//Get your IQueryable list of objects from your main DBContext(db)    
IQueryable<Object> objects = db.Object.Where(whatever where clause you desire);

//Create a new DBContext outside of the foreach loop    
using (DBContext dbMod = new DBContext())
{   
    //Loop through the IQueryable       
    foreach (Object object in objects)
    {
        //Get the same object you are operating on in the foreach loop from the new DBContext(dbMod) using the objects id           
        Object objectMod = dbMod.Object.Find(object.id);

        //Make whatever changes you need on objectMod
        objectMod.RightNow = DateTime.Now;

        //Invoke SaveChanges() on the dbMod context         
        dbMod.SaveChanges()
    }
}

The 2nd option is to get a list of database objects from the DBContext, but to select only the id's. And then iterate through the list of id's (presumably an int) and get the object corresponding to each int, and invoke SaveChanges() that way. The idea behind this method is grabbing a large list of integers, is a lot more efficient then getting a large list of db objects and calling .ToList() on the entire object. Here is an example of this method:

//Get the list of objects you want from your DBContext, and select just the Id's and create a list
List<int> Ids = db.Object.Where(enter where clause here)Select(m => m.Id).ToList();

var objects = Ids.Select(id => db.Objects.Find(id));

foreach (var object in objects)
{
    object.RightNow = DateTime.Now;
    db.SaveChanges()
}

You can do this conversion with the OpenSSL library

http://www.openssl.org/

Windows binaries can be found here:

Once you have the library installed, the command you need to issue is:

openssl x509 -in mycert.crt -out mycert.pem -outform PEM

If you want to know whether if debugging, everywhere in program. Use this.

Declare global variable.

bool isDebug=false;

Create function for checking debug mode

[ConditionalAttribute("DEBUG")]
    public static void isDebugging()
    {
        isDebug = true;
    }

In the initialize method call the function

isDebugging();

Now in the entire program. You can check for debugging and do the operations. Hope this Helps!

In that version of Android, when a view is inflated, the focus will be set to the first focusable control by default - and if there's no physical keyboard, the on-screen keyboard will pop up.

To fix this, explicitly set focus somewhere else. If focus is set to anything other than an EditText, the on-screen keyboard will not appear.

Have you tried testing this by running Android 1.5 in the emulator?

int i = Integer.parseInt(c, 2);

SWIFT 4

In Swift 4 you can use GCDs dispatch queues to lock resources.

class MyObject {
    private var internalState: Int = 0
    private let internalQueue: DispatchQueue = DispatchQueue(label:"LockingQueue") // Serial by default

    var state: Int {
        get {
            return internalQueue.sync { internalState }
        }

        set (newState) {
            internalQueue.sync { internalState = newState }
        }
    }
} 

Slight improvement to 360Airwalk solution. This imbeds the Anti Forgery Token within the javascript function, so @Html.AntiForgeryToken() no longer needs to be included on every view.

$(document).ready(function () {
    var securityToken = $('@Html.AntiForgeryToken()').attr('value');
    $('body').bind('ajaxSend', function (elm, xhr, s) {
        if (s.type == 'POST' && typeof securityToken != 'undefined') {
            if (s.data.length > 0) {
                s.data += "&__RequestVerificationToken=" + encodeURIComponent(securityToken);
            }
            else {
                s.data = "__RequestVerificationToken=" + encodeURIComponent(securityToken);
            }
        }
    });
});

Alternatively, if the method on Child is truly static (not a product of current props, state) you can define it on statics and then access it as you would a static class method. For example:

var Child = React.createClass({
  statics: {
    someMethod: function() {
      return 'bar';
    }
  },
  // ...
});

console.log(Child.someMethod()) // bar

Try using cmake itself. In the build directory, run:

cmake --build .

FOR METEOR USERS:

moment locales are not installed by default in meteor, you only get the 'en' locale with the default installation.

So you use the code as shown correctly in other answers:

moment.locale('it').format('LLL');

but it will remain in english until you install the locale you need.

There is a nice, clean way of adding individual locales for moment in meteor (supplied by rzymek).

Install the moment package in the usual meteor way with:

meteor add rzymek:moment

Then just add the locales that you need, e.g. for italian:

meteor add rzymek:moment-locale-it

Or if you really want to add all available locales (adds about 30k to your page):

meteor add rzymek:moment-locales

0123456789 is not a valid integer (usually zeros will be stripped)

I think something like this regexp would be better to use:

^[1-9]([0-9]*)$

(does not support signed numbers)

iframe have "sandbox" attribute that may block pop up etc

Use SHOW VARIABLES:

show variables like 'version';

arr = arr.filter(v => v);

as returned v is implicity converted to truthy

I know this is an old question but I believed the asker wanted the class, not the class name. I wrote a little method that will get the actual class. It is sort of cheaty and may not always work, but sometimes when you need the actual class, you will have to use this method...

/**
     * Get the caller class.
     * @param level The level of the caller class.
     *              For example: If you are calling this class inside a method and you want to get the caller class of that method,
     *                           you would use level 2. If you want the caller of that class, you would use level 3.
     *
     *              Usually level 2 is the one you want.
     * @return The caller class.
     * @throws ClassNotFoundException We failed to find the caller class.
     */
    public static Class getCallerClass(int level) throws ClassNotFoundException {
        StackTraceElement[] stElements = Thread.currentThread().getStackTrace();
        String rawFQN = stElements[level+1].toString().split("\\(")[0];
        return Class.forName(rawFQN.substring(0, rawFQN.lastIndexOf('.')));
    }

ssh-key with passphrase, with keychain

keychain is a small utility which manages ssh-agent on your behalf and allows the ssh-agent to remain running when the login session ends. On subsequent logins, keychain will connect to the existing ssh-agent instance. In practice, this means that the passphrase must be be entered only during the first login after a reboot. On subsequent logins, the unencrypted key from the existing ssh-agent instance is used. This can also be useful for allowing passwordless RSA/DSA authentication in cron jobs without passwordless ssh-keys.

To enable keychain, install it and add something like the following to ~/.bash_profile:

eval keychain --agents ssh --eval id_rsa From a security point of view, ssh-ident and keychain are worse than ssh-agent instances limited to the lifetime of a particular session, but they offer a high level of convenience. To improve the security of keychain, some people add the --clear option to their ~/.bash_profile keychain invocation. By doing this passphrases must be re-entered on login as above, but cron jobs will still have access to the unencrypted keys after the user logs out. The keychain wiki page has more information and examples.

Got this info from;

https://unix.stackexchange.com/questions/90853/how-can-i-run-ssh-add-automatically-without-password-prompt

Hope this helps

I have personally been able to automatically enter my passphrase upon terminal launch by doing this: (you can, of course, modify the script and fit it to your needs)

1. edit the bashrc file to add this script;

   Check if the SSH agent is awake

   if [ -z "$SSH_AUTH_SOCK" ] ; then exec ssh-agent bash -c "ssh-add ; $0" echo "The SSH agent was awakened" exit fi

   Above line will start the expect script upon terminal launch.

   ./ssh.exp

here's the content of this expect script

#!/usr/bin/expect

set timeout 20

set passphrase "test"

spawn "./keyadding.sh"

expect "Enter passphrase for /the/path/of/yourkey_id_rsa:"

send "$passphrase\r";

interact

Here's the content of my keyadding.sh script (you must put both scripts in your home folder, usually /home/user)

#!/bin/bash

ssh-add /the/path/of/yourkey_id_rsa

exit 0

I would HIGHLY suggest encrypting the password on the .exp script as well as renaming this .exp file to something like term_boot.exp or whatever else for security purposes. Don't forget to create the files directly from the terminal using nano or vim (ex: nano ~/.bashrc | nano term_boot.exp) and also a chmod +x script.sh to make it executable. A chmod +r term_boot.exp would be also useful but you'll have to add sudo before ./ssh.exp in your bashrc file. So you'll have to enter your sudo password each time you launch your terminal. For me, it's more convenient than the passphrase cause I remember my admin (sudo) password by the hearth.

Also, here's another way to do it I think; https://www.cyberciti.biz/faq/noninteractive-shell-script-ssh-password-provider/

Will certainly change my method for this one when I'll have the time.

From manual page,

git-reset - Reset current HEAD to the specified state
git reset [-q] [<tree-ish>] [--] <paths>...
In the first and second form, copy entries from <tree-ish> to the index.

for example, when we use git reset HEAD~1 it reset our current HEAD to HEAD~1

so when we use git reset 'some-deleted-file-path'

git assume 'some-deleted-file-path' as some commit point and try to reset out current HEAD to there.

And it ends up fail

fatal: ambiguous argument 'some-deleted-file-path': unknown revision or path not in the working tree.

In theory SMTP can be handled by either TCP, UDP, or some 3rd party protocol.

As defined in RFC 821, RFC 2821, and RFC 5321:

SMTP is independent of the particular transmission subsystem and requires only a reliable ordered data stream channel.

In addition, the Internet Assigned Numbers Authority has allocated port 25 for both TCP and UDP for use by SMTP.

In practice however, most if not all organizations and applications only choose to implement the TCP protocol. For example, in Microsoft's port listing port 25 is only listed for TCP and not UDP.

The big difference between TCP and UDP that makes TCP ideal here is that TCP checks to make sure that every packet is received and re-sends them if they are not whereas UDP will simply send packets and not check for receipt. This makes UDP ideal for things like streaming video where every single packet isn't as important as keeping a continuous flow of packets from the server to the client.

Considering SMTP, it makes more sense to use TCP over UDP. SMTP is a mail transport protocol, and in mail every single packet is important. If you lose several packets in the middle of the message the recipient might not even receive the message and if they do they might be missing key information. This makes TCP more appropriate because it ensures that every packet is delivered.

Update: If you are using Angular 1.2+, use ng-repeat-start. See @jmagnusson's answer.

Otherwise, how about putting the ng-repeat on tbody? (AFAIK, it is okay to have multiple <tbody>s in a single table.)

<tbody ng-repeat="row in array">
  <tr ng-repeat="item in row">
     <td>{{item}}</td>

Edit: The bitset stuff below is maybe an interesting read, but the answer itself is a bit dated. Some of this functionality is changing around in 2.x. Also Slawek points out in another answer that the terms query is an easy way to DRY up the search in this case. Refactored at the end for current best practices. —nz

You'll probably want a Bool Query (or more likely Filter alongside another query), with a should clause.

The bool query has three main properties: must, should, and must_not. Each of these accepts another query, or array of queries. The clause names are fairly self-explanatory; in your case, the should clause may specify a list filters, a match against any one of which will return the document you're looking for.

From the docs:

In a boolean query with no must clauses, one or more should clauses must match a document. The minimum number of should clauses to match can be set using the minimum_should_match parameter.

Here's an example of what that Bool query might look like in isolation:

{
  "bool": {
    "should": [
      { "term": { "tag": "c" }},
      { "term": { "tag": "d" }}
    ]
  }
}

And here's another example of that Bool query as a filter within a more general-purpose Filtered Query:

{
  "filtered": {
    "query": {
      "match": { "title": "hello world" }
    },
    "filter": {
      "bool": {
        "should": [
          { "term": { "tag": "c" }},
          { "term": { "tag": "d" }}
        ]
      }
    }
  }
}

Whether you use Bool as a query (e.g., to influence the score of matches), or as a filter (e.g., to reduce the hits that are then being scored or post-filtered) is subjective, depending on your requirements.

It is generally preferable to use Bool in favor of an Or Filter, unless you have a reason to use And/Or/Not (such reasons do exist). The Elasticsearch blog has more information about the different implementations of each, and good examples of when you might prefer Bool over And/Or/Not, and vice-versa.

Elasticsearch blog: All About Elasticsearch Filter Bitsets

Update with a refactored query...

Now, with all of that out of the way, the terms query is a DRYer version of all of the above. It does the right thing with respect to the type of query under the hood, it behaves the same as the bool + should using the minimum_should_match options, and overall is a bit more terse.

Here's that last query refactored a bit:

{
  "filtered": {
    "query": {
      "match": { "title": "hello world" }
    },
    "filter": {
      "terms": {
        "tag": [ "c", "d" ],
        "minimum_should_match": 1
      }
    }
  }
}

The answer was already given but if you already have an Instance of T then you can do this:

T t; //Assuming you already have this object instantiated or given by parameter.
int length;
T[] ts = (T[]) Array.newInstance(t.getClass(), length);

Hope, I could Help, Ferdi265

Thanks Chad! To show all the errors associated with the key, here's what I came up with. For some reason the base Html.ValidationMessage helper only shows the first error associated with the key.

    <%= Html.ShowAllErrors(mykey) %>

HtmlHelper:

    public static String ShowAllErrors(this HtmlHelper helper, String key) {
        StringBuilder sb = new StringBuilder();
        if (helper.ViewData.ModelState[key] != null) {
            foreach (var e in helper.ViewData.ModelState[key].Errors) {
                TagBuilder div = new TagBuilder("div");
                div.MergeAttribute("class", "field-validation-error");
                div.SetInnerText(e.ErrorMessage);
                sb.Append(div.ToString());
            }
        }
        return sb.ToString();
    }

If you want the logical size of the array, you can traverse all the values in the array and check them against zero. Increment the value if it is not zero and that would be the logical size. Because array size is fixed, you do not have any inbuilt method, may be you should have a look at collections.

   @RequestMapping("/op")
   public ModelAndView method(Map<String, Object> model) {
       model.put("att", "helloooo");
       return new ModelAndView("dom/op");
   }

In your .js

<script>
    var valVar = [[${att}]];
</script>

If you are using git 1.7.x, you can run the following command to set the remote tracking branch.

git branch --set-upstream feature/123-sandbox-tests origin/feature/123-sandbox-tests

Then you can simply use git push to push all the changes. For a more complete answer, please see the accepted answer to a similar question here.

If you only want to push the current branch with the push command, then you can change the push behaviour to upstream:

git config --global push.default upstream

You can't.

You can, however, use margins to effect the same result.

You can use x = func()[0] to return the first value, x = func()[1] to return the second, and so on.

If you want to get multiple values at a time, use something like x, y = func()[2:4].

I Followed all the things mentioned in this thread but still facing same issue-

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

I wanted to add an answer if the checkboxes are being generated in a loop. For example if your structure is like this (Assuming you are using server side constructs on your View, like a foreach loop):

<li id="checkboxlist" class="list-group-item card">
  <div class="checkbox checkbox-inline">
    <label><input type="checkbox" id="checkbox1">Checkbox 1</label>
    <label><input type="checkbox" id="checkbox2">Checkbox 2</label>
  </div>
</li>

<li id="checkboxlist" class="list-group-item card">
  <div class="checkbox checkbox-inline">
    <label><input type="checkbox" id="checkbox1">Checkbox 1</label>
    <label><input type="checkbox" id="checkbox2">Checkbox 2</label>
  </div>
</li>

Corresponding Jquery:

$(".list-group-item").each(function (i, li) {
  var currentli = $(li);
  $(currentli).find("#checkbox1").on('change', function () {
       $(currentli).find("#checkbox2").not(this).prop('checked',false);
  });

  $(currentli).find("#checkbox2").on('change', function () {
       $(currentli).find("#checkbox1").not(this).prop('checked', false);
  });
});

sudo. su. chmod 04500. (setuid() & seteuid(), but they require you to already be root. E..g. chmod'ed 04***.)

Take care. These can open "interesting" security holes...

Depending on what you are doing, you may not need root. (For instance: I'll often chmod/chown /dev devices (serial ports, etc) (under sudo root) so I can use them from my software without being root. On the other hand, that doesn't work so well when loading/unloading kernel modules...)

First of all, android.graphics.Color is a class thats composed of only static methods. How and why did you create a new android.graphics.Color object? (This is completely useless and the object itself stores no data)

But anyways... I'm going to assume your using some object that actually stores data...

A integer is composed of 4 bytes (in java). Looking at the function getRGB() from the standard java Color object we can see java maps each color to one byte of the integer in the order ARGB (Alpha-Red-Green-Blue). We can replicate this behavior with a custom method as follows:

public int getIntFromColor(int Red, int Green, int Blue){
    Red = (Red << 16) & 0x00FF0000; //Shift red 16-bits and mask out other stuff
    Green = (Green << 8) & 0x0000FF00; //Shift Green 8-bits and mask out other stuff
    Blue = Blue & 0x000000FF; //Mask out anything not blue.

    return 0xFF000000 | Red | Green | Blue; //0xFF000000 for 100% Alpha. Bitwise OR everything together.
}

This assumes you can somehow retrieve the individual red, green and blue colour components and that all the values you passed in for the colours are 0-255.

If your RGB values are in form of a float percentage between 0 and 1 consider the following method:

public int getIntFromColor(float Red, float Green, float Blue){
    int R = Math.round(255 * Red);
    int G = Math.round(255 * Green);
    int B = Math.round(255 * Blue);

    R = (R << 16) & 0x00FF0000;
    G = (G << 8) & 0x0000FF00;
    B = B & 0x000000FF;

    return 0xFF000000 | R | G | B;
}

As others have stated, if you're using a standard java object, just use getRGB();

If you decide to use the android color class properly you can also do:

int RGB = android.graphics.Color.argb(255, Red, Green, Blue); //Where Red, Green, Blue are the RGB components. The number 255 is for 100% Alpha

or

int RGB = android.graphics.Color.rgb(Red, Green, Blue); //Where Red, Green, Blue are the RGB components.

as others have stated... (Second function assumes 100% alpha)

Both methods basically do the same thing as the first method created above.

User data is very important for a good developer, so don't ask again and again for same data, use some logic to correct some basic error in data.

Before validation of Email: First you have to remove all illegal characters from email.

//This will Remove all illegal characters from email
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

after that validate your email address using this filter_var() function.

filter_var($email, FILTER_VALIDATE_EMAIL)) // To Validate the email

For e.g.

<?php
$email = "[email protected]";

// Remove all illegal characters from email
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

// Validate email
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    echo $email." is a valid email address";
} else {
    echo $email." is not a valid email address";
}
?>

As already recommended, you can use tree. But for using it together with restructured text some additional parameters were required.

The standard tree output will not be printed if your're using pandoc to produce pdf.

If your string constraint is not just one string you can drop those corresponding rows with:

df = df[~df['your column'].isin(['list of strings'])]

The above will drop all rows containing elements of your list

public enum Direction {
    NORTH, EAST, SOUTH, WEST;

    public Direction getOppositeDirection(){
        return Direction.values()[(this.ordinal() + 2) % 4];
    }
}

Enums have a static values method that returns an array containing all of the values of the enum in the order they are declared. source

since NORTH gets 1, EAST gets 2, SOUTH gets 3, WEST gets 4; you can create a simple equation to get the opposite one:

(value + 2) % 4

Several possiblies that causes this problem. The root cause is mismatched of compiler version between projects and IDE. For windows environment you can refer to this blog to do the detail troubleshooting.

Assuming that enum is numbered sequentially is error prone. Moreover, you may want to iterate over selected enumerators only. If that subset is small, looping over it explicitly might be an elegant choice:

enum Item { Man, Wolf, Goat, Cabbage }; // or enum class

for (auto item : {Wolf, Goat, Cabbage}) { // or Item::Wolf, ...
    // ...
}

I had the same problem with a dummy app that happened to have the same name as my final app and couldn't publish because the App Name is already in use

To fix it, instead of deleting it(which you can't) I just changed the name of the dummy app to something random and hit SAVE. Then I was able to add the new app with the proper name

To expand on Dennis's answer, use awk's -v option to pass the i and j values:

# print the j'th field of the i'th line
awk -v i=5 -v j=3 'FNR == i {print $j}'

Remember that the correct file to be configured in this situation is not the httpd.conf in the phpMyAdmin alias, but in bin/apache/your_version/conf/httpd.conf.

Look for the following line:

DocumentRoot "c:/wamp/www/"

#
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
#
# First, we configure the "default" to be a very restrictive set of
# features.
#
<Directory />
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Allow from all
</Directory>

Make sure it is set to Allow from all...

If not, phpMyAdmin might even work, but not your root and other folders under it. Also, remember to restart WAMP and then put online...

This solved my headache.

You can set the ReadOnly property to true.

Quoth the link:

When this property is set to true, the contents of the control cannot be changed by the user at runtime. With this property set to true, you can still set the value of the Text property in code. You can use this feature instead of disabling the control with the Enabled property to allow the contents to be copied and ToolTips to be shown.

Some time ago I wrote simple Webcam Capture API which can be used for that. The project is available on Github.

Example code:

Webcam webcam = Webcam.getDefault();
webcam.open();
try {
  ImageIO.write(webcam.getImage(), "PNG", new File("test.png"));
} catch (IOException e) {
  e.printStackTrace();
} finally {
  webcam.close();
}

Note: In hindsight this was a quick and dirty answer, and may not work in all situations. To have a reliable solution, see Tim Down's answer (copy pasting that here as this answer is still getting views and upvotes):

You can't do this reliably with the keyup event. If you want to know something about the character that was typed, you have to use the keypress event instead.

The following example will work all the time in most browsers but there are some edge cases that you should be aware of. For what is in my view the definitive guide on this, see http://unixpapa.com/js/key.html.

$("input").keypress(function(e) {
    if (e.which !== 0) {
        alert("Character was typed. It was: " + String.fromCharCode(e.which));
    }
});

keyup and keydown give you information about the physical key that was pressed. On standard US/UK keyboards in their standard layouts, it looks like there is a correlation between the keyCode property of these events and the character they represent. However, this is not reliable: different keyboard layouts will have different mappings.

The following was the original answer, but is not correct and may not work reliably in all situations.

To match the keycode with a word character (eg., a would match. space would not)

$("input").keyup(function(event)
{ 
    var c= String.fromCharCode(event.keyCode);
    var isWordcharacter = c.match(/\w/);
}); 

Ok, that was a quick answer. The approach is the same, but beware of keycode issues, see this article in quirksmode.

This function will clear the sheet data starting from specified row and column :

Sub ClearWKSData(wksCur As Worksheet, iFirstRow As Integer, iFirstCol As Integer)

Dim iUsedCols As Integer
Dim iUsedRows As Integer

iUsedRows = wksCur.UsedRange.Row + wksCur.UsedRange.Rows.Count - 1
iUsedCols = wksCur.UsedRange.Column + wksCur.UsedRange.Columns.Count - 1

If iUsedRows > iFirstRow And iUsedCols > iFirstCol Then
    wksCur.Range(wksCur.Cells(iFirstRow, iFirstCol), wksCur.Cells(iUsedRows, iUsedCols)).Clear
End If

End Sub

This is universal solution for conditions wiht more same results.

<?php
$your_name1_finded="somethnig searched"; //$your_name1_finded must be finded in previous select

$result = db_query("SELECT your_name1 FROM your_table WHERE your_name=your_condition ORDER BY your_name1, your_name2"); //Get all our ids

$i=0;
while($row = db_fetch_assoc($result)) { //Loop through our rows
    $i++;
    $current_row[$i]=$row['your_name1'];// field with results
    if($row['your_name1'] == $your_name1_finded) {//If we haven't hit our current row yet
        $yid=$i;
    }
}
//buttons
if ($current_row[$yid-1]) $out_button.= "<a  class='button' href='/$your_url/".$current_row[$yid-1]."'>BUTTON_PREVIOUS</a>";
if ($current_row[$yid+1]) $out_button.= "<a  class='button' href='/$your_url/".$current_row[$yid+1]."'>BUTTON_NEXT</a>";

echo $out_button;//display buttons
?>

One key thing to remember that message.max.bytes attribute must be in sync with the consumer's fetch.message.max.bytes property. the fetch size must be at least as large as the maximum message size otherwise there could be situation where producers can send messages larger than the consumer can consume/fetch. It might worth taking a look at it.
Which version of Kafka you are using? Also provide some more details trace that you are getting. is there some thing like ... payload size of xxxx larger than 1000000 coming up in the log?

Since value is the last entry, you can do:

metrics.sort_by(&:last)

If a method (instance or static) only references variables scoped within that method then it is thread safe because each thread has its own stack:

In this instance, multiple threads could call ThreadSafeMethod concurrently without issue.

public class Thing
{
    public int ThreadSafeMethod(string parameter1)
    {
        int number; // each thread will have its own variable for number.
        number = parameter1.Length;
        return number;
    }
}

This is also true if the method calls other class method which only reference locally scoped variables:

public class Thing
{
    public int ThreadSafeMethod(string parameter1)
    {
        int number;
        number = this.GetLength(parameter1);
        return number;
    }

    private int GetLength(string value)
    {
        int length = value.Length;
        return length;
    }
}

If a method accesses any (object state) properties or fields (instance or static) then you need to use locks to ensure that the values are not modified by a different thread.

public class Thing
{
    private string someValue; // all threads will read and write to this same field value

    public int NonThreadSafeMethod(string parameter1)
    {
        this.someValue = parameter1;

        int number;

        // Since access to someValue is not synchronised by the class, a separate thread
        // could have changed its value between this thread setting its value at the start 
        // of the method and this line reading its value.
        number = this.someValue.Length;
        return number;
    }
}

You should be aware that any parameters passed in to the method which are not either a struct or immutable could be mutated by another thread outside the scope of the method.

To ensure proper concurrency you need to use locking.

for further information see lock statement C# reference and ReadWriterLockSlim.

lock is mostly useful for providing one at a time functionality,
ReadWriterLockSlim is useful if you need multiple readers and single writers.

To change the default encoding used for all workspaces you can do the following:

Create a defaults.ini file in the Eclipse configuration folder. For example, if Eclipse is installed in C:/Eclipse create C:/Eclipse/configuration/defaults.ini. The file should contain:

org.eclipse.core.resources/encoding=UTF-8

If you want to set the line terminator to UNIX values you can also add:

org.eclipse.core.runtime/line.separator=\n

In eclipse.ini in the Eclipse install folder (e.g., C:/Eclipse) add the following lines:

-plugincustomization 
D:/Java/Eclipse/configuration/defaults.ini

You might need to play around with where you put it. Inserting it before the "-product" option seemed to work.

I got this from some forum. I hope it will be useful for you.

Applies to Ubuntu 14.04 and later releases. Make sure to backup following files before making any changes.

1.Open /etc/apache2/apache2.conf and search for <Directory /var/www/> directive and replace path with /home/<USERNAME>/public_html. You can use * instead of .

2.Open /etc/apache2/sites-available/000-default.conf and replace DocumentRoot value property from /var/www/html to /home/<USERNAME>/public_html. Also <Directory /var/www/html> to <Directory /home/<USERNAME>/public_html.

3.Open /etc/mods-available/php7.1.conf. Find and comment following code

<IfModule mod_userdir.c>
    <Directory /home/*/public_html>
        php_admin_flag engine Off
    </Directory>
</IfModule>

Do not turn ON php_admin_flag engine OFF flag as reason is mentioned in comment above Directive code. Also php version can be 5.0, 7.0 or anything which you have installed.

Create public_html directory in home/<USERNAME>.

Restart apache service by executing command sudo service apache2 restart.

Test by running sample script on server.

string Folder = Directory.GetParent(path).Name;

drop procedure if exists doWhile;
DELIMITER //  
CREATE PROCEDURE doWhile()   
BEGIN
DECLARE i INT DEFAULT 2376921001; 
WHILE (i <= 237692200) DO
    INSERT INTO `mytable` (code, active, total) values (i, 1, 1);
    SET i = i+1;
END WHILE;
END;
//  

CALL doWhile(); 

Yippe - an update to AWS CLI allows you to recursively ls through buckets...

aws s3 ls s3://<bucketname> --recursive  | grep -v -E "(Bucket: |Prefix: |LastWriteTime|^$|--)" | awk 'BEGIN {total=0}{total+=$3}END{print total/1024/1024" MB"}'

Or you can just create your own MediaTypeFormatter. I use this for text/html. If you add text/plain to it, it'll work for you too:

public class TextMediaTypeFormatter : MediaTypeFormatter
{
    public TextMediaTypeFormatter()
    {
        SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
    }

    public override Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger)
    {
        return ReadFromStreamAsync(type, readStream, content, formatterLogger, CancellationToken.None);
    }

    public override async Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger, CancellationToken cancellationToken)
    {
        using (var streamReader = new StreamReader(readStream))
        {
            return await streamReader.ReadToEndAsync();
        }
    }

    public override bool CanReadType(Type type)
    {
        return type == typeof(string);
    }

    public override bool CanWriteType(Type type)
    {
        return false;
    }
}

Finally you have to assign this to the HttpMethodContext.ResponseFormatter property.

Android Studio 3

The answers that talk about Maven Central are dated since Android Studio uses JCenter as the default repository center now. Your project's build.gradle file should have something like this:

repositories {
    google()
    jcenter()
}

So as long as the developer has their Maven repository there (which Picasso does), then all you would have to do is add a single line to the dependencies section of your app's build.gradle file.

dependencies {
    // ...
    implementation 'com.squareup.picasso:picasso:2.5.2'
}

Perfectly described here https://www.smashingmagazine.com/2014/05/moving-git-repository-new-server/

First, we have to fetch all of the remote branches and tags from the existing repository to our local index:

git fetch origin

We can check for any missing branches that we need to create a local copy of:

git branch -a

Let’s use the SSH-cloned URL of our new repository to create a new remote in our existing local repository:

git remote add new-origin [email protected]:manakor/manascope.git

Now we are ready to push all local branches and tags to the new remote named new-origin:

git push --all new-origin 
git push --tags new-origin

Let’s make new-origin the default remote:

git remote rm origin

Rename new-origin to just origin, so that it becomes the default remote:

git remote rename new-origin origin

In the Environment setup, we had undefined = StrictUndefined, which prevented undefined values from being set to anything. This fixed it:

from jinja2 import Undefined
JINJA2_ENVIRONMENT_OPTIONS = { 'undefined' : Undefined }

Updated for Bootstrap 4

Bootstrap 4 now includes a position-fixed class for this purpose so there is no need for additional CSS...

<div class="container">
    <div class="row">
        <div class="col-lg-3">
            <div class="position-fixed">
                Fixed content
            </div>
        </div>
        <div class="col-lg-9">
            Normal scrollable content
        </div>
    </div>
</div>

An enhancement of the hacky idea by Nick Craver to put custom HTML in a jquery dialog title:

var newtitle= '<b>HTML TITLE</b>';
$(".selectorUsedToCreateTheDialog").parent().find("span.ui-dialog-title").html(newtitle);

Go to your HTTP bindings in IIS (select your website, then on the right click on Bindings...). Delete your SSL and your HTTP binding. Re-Add them.

This usually fixes this for me.

In general,

variable=$(command)

or

variable=`command`

The latter one is the old syntax, prefer $(command).

Note: variable = .... means execute the command variable with the first argument =, the second ....

Just click on attach source and select folder path ... name will be same as folder name (in my case). Remember one thing you need to select path upto project folder base location with "\" at suffix ex D:\MyProject\

As the name suggests, Layout weight specifies what amount or percentage of space a particular field or widget should occupy the screen space.
If we specify weight in horizontal orientation, then we must specify layout_width = 0px.
Similarly, If we specify weight in vertical orientation, then we must specify layout_height = 0px.

On 2017-01-25 Apple released a technical Q&A regarding this error:

Apple Technical Q&A QA1941

Handling “The network connection was lost” Errors

A: NSURLErrorNetworkConnectionLost is error -1005 in the NSURLErrorDomain error domain, and is displayed to users as “The network connection was lost”. This error means that the underlying TCP connection that’s carrying the HTTP request disconnected while the HTTP request was in progress (see below for more information about this). In some circumstances NSURLSession may retry such requests automatically (specifically, if the request is idempotent) but in other circumstances that’s not allowed by the HTTP standards.

https://developer.apple.com/library/archive/qa/qa1941/_index.html#//apple_ref/doc/uid/DTS40017602

Node has builtin support for gzip and deflate via the zlib module:

var zlib = require('zlib');

zlib.gunzip(gzipBuffer, function(err, result) {
    if(err) return console.error(err);

    console.log(result);
});

Edit: You can even pipe the data directly through e.g. Gunzip (using request):

var request = require('request'),
    zlib = require('zlib'),
    fs = require('fs'),
    out = fs.createWriteStream('out');

// Fetch http://example.com/foo.gz, gunzip it and store the results in 'out'
request('http://example.com/foo.gz').pipe(zlib.createGunzip()).pipe(out);

For tar archives, there is Isaacs' tar module, which is used by npm.

Edit 2: Updated answer as zlib doesn't support the zip format. This will only work for gzip.

In Manifest theme sets with style name (AppTheme and myDialog)/ You can set new styles in styles.xml

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MyActivity2"
        android:label="@string/title_activity_my_activity2"
        android:theme="@style/myDialog"
        >
    </activity>
</application>

styles.xml example

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.Black">
    <!-- Customize your theme here. -->
</style>

<style name="myDialog" parent="android:Theme.Dialog">

</style>

In parent you set actualy the theme

It's to execute a second statement if the first statement ends succesfully. Like an if statement:

 if (1 == 1 && 2 == 2)
  echo "test;"

Its first tries if 1==1, if that is true it checks if 2==2

Add this dependency

compile 'com.google.android.gms:play-services:9.4.0'

This is quite late but anyone going through the same problem might benefit from this answer.First try to add browser by running below command ionic platform add browser and then run command ionic run browser.

which is the difference between ionic serve and ionic run browser?

Ionic serve - runs your app as a website (meaning it doesn't have any Cordova capabilities). Ionic run browser - runs your app in the Cordova browser platform, which will inject cordova.js and any plugins that have browser capabilities

You can refer this link to know more difference between ionic serve and ionic run browser command

Update

From Ionic 3 this command has been changed. Use the command below instead;

ionic cordova platform add browser

ionic cordova run browser

You can find out which version of ionic you are using by running: ionic --version

A quick guess if you post your code can say for sure but you might have done something along the lines of

HashMap<String, Object> test = new HashMap();

which will produce the warning when you need to do

HashMap<String, Object> test = new HashMap<String, Object>();

it might be worth looking at

Generics in the Java Programming Language

if your unfamiliar with what needs to be done.

Continuing from Pete's example above, to do it directly in the cmd window, use a single %, eg:

cd c:\test\folder A
for %X in (*)do echo %~nxX

(Note that special files like desktop.ini will not show up.)

It's also possible to redirect the output to a file using >>:

cd c:\test\folder A
for %X in (*)do echo %~nxX>>c:\test\output.txt

For a real example, assuming you want to robocopy all files from folder-A to folder-B (non-recursively):

cd c:\test\folder A
for %X in (*)do robocopy . "c:\test\folder B" "%~nxX" /dcopy:dat /copyall /v>>c:\test\output.txt

and for all folders (recursively):

cd c:\test\folder A
for /d %X in (*)do robocopy "%X" "C:\test\folder B\%X" /e /copyall /dcopy:dat /v>>c:\test\output2.txt

Apache/HTTPD tends to be around in most enterprises or if you're using Centos/etc at home. So, if you have that around, you can do a proxy very easily to add the necessary CORS headers.

I have a blog post on this here as I suffered with it quite a few times recently. But the important bit is just adding this to your /etc/httpd/conf/httpd.conf file and ensuring you are already doing "Listen 80":

<VirtualHost *:80>
    <LocationMatch "/SomePath">
       ProxyPass http://target-ip:8080/SomePath
       Header add "Access-Control-Allow-Origin" "*"
    </LocationMatch>
</VirtualHost>

This ensures that all requests to URLs under your-server-ip:80/SomePath route to http://target-ip:8080/SomePath (the API without CORS support) and that they return with the correct Access-Control-Allow-Origin header to allow them to work with your web-app.

Of course you can change the ports and target the whole server rather than SomePath if you like.

I always write it like this:

var foo:string;

if(!foo){
   foo="something";    
}

This will work fine and I think it's very readable.

I was getting this same error, in our case it was caused by a load balancer. We hade to make sure that the persistance was set to Source IP. Otherwise the login form was opened by one server, and processed by the other, which would fail to set the authentication cookie correctly. Maybe this helps someone else

I know this is a bit old, but I had the same problem and my search brought me here. I wanted two select elements and a button all inline, which worked in 2 but not 3. I ended up wrapping the three elements in <form class="form-inline">...</form>. This actually worked perfectly for me.

You will not be able to retrieve a plain text password from wordpress.

Wordpress use a 1 way encryption to store the passwords using a variation of md5. There is no way to reverse this.

See this article for more info http://wordpress.org/support/topic/how-is-the-user-password-encrypted-wp_hash_password

Have you tried the following?:

textbox1.text = System.DateTime.Today.ToString("MM/dd/yy");

Be aware that 2 digit years could be bad in the future...

1. Wrap your form in a div.
2. Set the div's display to block and text-align to center (this will center the contained form).
3. Set the form's display to inline-block (auto-sizes to content), left and right margins to auto (centers it horizontally), and text-align to left (or else its children will be center-aligned too).

HTML:

<div class="form">
    <form name="Form1" action="mypage.asp" method="get">
        ...
    </form>
</div>

CSS:

div.form
{
    display: block;
    text-align: center;
}
form
{
    display: inline-block;
    margin-left: auto;
    margin-right: auto;
    text-align: left;
}

$text='<span style="font-weight: bold;">Foo</span>';
$text=preg_replace( '/<span style="font-weight: bold;">(.*?)<\/span>/', '<strong>$1</strong>',$text);

Note: only work for your example.

If you are solely interested in outputting the JSON somewhere in your HTML, you could also use a pipe inside an interpolation. For example:

<p> {{ product | json }} </p>

I am not entirely sure it works for every AngularJS version, but it works perfectly in my Ionic App (which uses Angular 2+).

To make it clear, in addition to @SLaks' answer, that meant you need to change this line :

List<RootObject> datalist = JsonConvert.DeserializeObject<List<RootObject>>(jsonstring);

to something like this :

RootObject datalist = JsonConvert.DeserializeObject<RootObject>(jsonstring);

I had a different problem from what all of the answers so far mentioned!

I should start off by saying that I had it in Visual Studio, and not SQL Server Express but the solution should be exactly the same.

Well, god, it's actually really simple and maybe a bit foolish. When I tried to create a database and Visual Studio suggested the name of the SQL Server it gave me my Windows username and since it's actually the name of the server I went for it.

In reality it actually was my Windows username + \SQLEXPRESS. If you didn't change any settings this is probably yours too. If it works, stop reading; this is my answer. If it doesn't work maybe the name is different.

If, like me, you only had this problem in Visual Studio to check what is yours follow these steps:

1. Open SQL Server Management Studio^icon.
2. If you don't see your server (docked to the left by default) press F8 or go to View -> Object Explorer.
3. Right click on the name of the server and choose Properties (The last item)
4. At the bottom left you can see your server's actual name under "Server" (not Connection, but above it).

This is the name of the server and this is what you should attempt to connect to! not what Visual Studio suggests!

Have you heard about the jQuery Waypoint plugin.

Below is the simple way of calling a waypoints plugin and having the page load more Content once you reaches the bottom on scroll :

$(document).ready(function() {
    var $loading = $("<div class='loading'><p>Loading more items&hellip;</p></div>"),
    $footer = $('footer'),
    opts = {
        offset: '100%'
    };

    $footer.waypoint(function(event, direction) {
        $footer.waypoint('remove');
        $('body').append($loading);
        $.get($('.more a').attr('href'), function(data) {
            var $data = $(data);
            $('#container').append($data.find('.article'));
            $loading.detach();
            $('.more').replaceWith($data.find('.more'));
            $footer.waypoint(opts);
        });
    }, opts);
});

When you open the file you want to write to, open it with a specific encoding that can handle all the characters.

with open('filename', 'w', encoding='utf-8') as f:
    print(r['body'], file=f)

This is bit out of context but in case you are here because you want to tag a specific commit like i do

Here's a command to do that :-

Example:

git tag -a v1.0 7cceb02 -m "Your message here"

Where 7cceb02 is the beginning part of the commit id.

You can then push the tag using git push origin v1.0.

You can do git log to show all the commit id's in your current branch.

The code seems working to me. I think the same with @Iothar.

Check to see if you include the required headers, to compile. If it is compiled, check to see if there is such a file, and everything, names etc, matches, and also check to see that you have a right to read the file.

To make a cross check, check if you can open it with fopen..

FILE *f = fopen("C:/Demo.txt", "r");
if (f)
  printf("fopen success\n");

I would do something like this but i bet there is a simpler way. i think the sql from linqtosql would use a select from person Where NOT EXIST(select from your exclusion list)

static class Program
{
    public class Person
    {
        public string Key { get; set; }
        public Person(string key)
        {
           Key = key;
        }
    }
    public class NotPerson
    {
        public string Key { get; set; }
        public NotPerson(string key)
        {
           Key = key;
        }
    }
    static void Main()
    {

       List<Person> persons = new List<Person>()
       { 
           new Person ("1"),
           new Person ("2"),
           new Person ("3"),
           new Person ("4")
       };

       List<NotPerson> notpersons = new List<NotPerson>()
       { 
           new NotPerson ("3"),
           new NotPerson ("4")
       };

       var filteredResults = from n in persons
                             where !notpersons.Any(y => n.Key == y.Key)
                             select n;

       foreach (var item in filteredResults)
       {
          Console.WriteLine(item.Key);
       }
    }
 }

If you are needing this to get user's home dir, below could be considered as portable (win32 and linux at least), part of a standard library.

>>> os.path.expanduser('~')
'C:\\Documents and Settings\\johnsmith'

Also you could parse such string to get only last path component (ie. user name).

See: os.path.expanduser

Use pass for no-op:

if x == 0:
  pass
else:
  print "x not equal 0"

And here's another example:

def f():
  pass

Or:

class c:
  pass

I am not very good with this but KeyboardEvent => see KeyboardEvent is initialized with initKeyEvent .
Here is an example for emitting event on <input type="text" /> element

document.getElementById("txbox").addEventListener("keypress", function(e) {_x000D_
  alert("Event " + e.type + " emitted!\nKey / Char Code: " + e.keyCode + " / " + e.charCode);_x000D_
}, false);_x000D_
_x000D_
document.getElementById("btn").addEventListener("click", function(e) {_x000D_
  var doc = document.getElementById("txbox");_x000D_
  var kEvent = document.createEvent("KeyboardEvent");_x000D_
  kEvent.initKeyEvent("keypress", true, true, null, false, false, false, false, 74, 74);_x000D_
  doc.dispatchEvent(kEvent);_x000D_
}, false);

<input id="txbox" type="text" value="" />_x000D_
<input id="btn" type="button" value="CLICK TO EMIT KEYPRESS ON TEXTBOX" />

Just for the sake of using XOR to answer a relatively straight-forward problem...

return a ^ b ? c : a

For 'C' there is alternative (more complex) use of [s]printf that does not require any malloc() or pre-formatting, when custom padding is desired.

The trick is to use '*' length specifiers (min and max) for %s, plus a string filled with your padding character to the maximum potential length.

int targetStrLen = 10;           // Target output length  
const char *myString="Monkey";   // String for output 
const char *padding="#####################################################";

int padLen = targetStrLen - strlen(myString); // Calc Padding length
if(padLen < 0) padLen = 0;    // Avoid negative length

printf("[%*.*s%s]", padLen, padLen, padding, myString);  // LEFT Padding 
printf("[%s%*.*s]", myString, padLen, padLen, padding);  // RIGHT Padding 

The "%*.*s" can be placed before OR after your "%s", depending desire for LEFT or RIGHT padding.

[####Monkey] <-- Left padded, "%*.*s%s"
[Monkey####] <-- Right padded, "%s%*.*s"

I found that the PHP printf (here) does support the ability to give a custom padding character, using the single quote (') followed by your custom padding character, within the %s format.
printf("[%'#10s]\n", $s); // use the custom padding character '#'
produces:
[####monkey]

Paste my contains example here:

//table[contains(@class, "EC_result")]/tbody

Just give your desired path if file does not exist earlier;

        from os.path import abspath
        with open ('C:\\Users\\Admin\\Desktop\\results.txt', mode = 'w') as final1:
            print(final1.write('This is my new file.'))

        print(f'Text has been processed and saved at {abspath(final1.name)}')

Output will be:

Text has been processed and saved at C:\Users\Admin\Desktop\results.txt

The new spread operator makes it even easier to apply multiple CSS classes as array:

Try

<button [ngClass]="type === 'mybutton' ? namespace + '-mybutton' : ''"></button>

instead.

or

<button [ngClass]="[type === 'mybutton' ? namespace + '-mybutton' : '']"></button>

or even

<button class="{{type === 'mybutton' ? namespace + '-mybutton' : ''}}"></button>

will work but extra benefit of using ngClass is that it does not overwrite other classes that are added by any other method( eg: [class.xyz] directive or class attribute, etc.) as class does.

Angular 9 Update

The new compiler, Ivy, brings more clarity and predictability to what happens when there are different types of class-bindings on the same element. Read More about it here.

ngClass takes three types of input

• Object: each key corresponds to a CSS class name, you can't have dynamic keys, because key 'key' "key" are all same, and [key] is not supported AFAIK.
• Array: can only contain list of classes, no conditions, although ternary operator works
• String/ expression: just like normal class attribute

.erb-image-wrapper img{
    max-width:100% !important;
    height:auto;
    display:block;
}

Worked for me.
Thanks for MrMisterMan for his assistance.

I hide the warnings in the pink boxes by running the following code in a cell:

from IPython.display import HTML
HTML('''<script>
code_show_err=false; 
function code_toggle_err() {
 if (code_show_err){
 $('div.output_stderr').hide();
 } else {
 $('div.output_stderr').show();
 }
 code_show_err = !code_show_err
} 
$( document ).ready(code_toggle_err);
</script>
To toggle on/off output_stderr, click <a href="javascript:code_toggle_err()">here</a>.''')
