Programs & Examples On #Strsplit

Here is a base R one liner that overlaps a number of previous solutions, but returns a data.frame with the proper names.

out <- setNames(data.frame(before$attr,
                  do.call(rbind, strsplit(as.character(before$type),
                                          split="_and_"))),
                  c("attr", paste0("type_", 1:2)))
out
  attr type_1 type_2
1    1    foo    bar
2   30    foo  bar_2
3    4    foo    bar
4    6    foo  bar_2

It uses strsplit to break up the variable, and data.frame with do.call/rbind to put the data back into a data.frame. The additional incremental improvement is the use of setNames to add variable names to the data.frame.

x = list(1, 2, 3, 4)
x2 = list(1:4)
all.equal(x,x2)

is not the same because 1:4 is the same as c(1,2,3,4). If you want them to be the same then:

x = list(c(1,2,3,4))
x2 = list(1:4)
all.equal(x,x2)

If the number of list items is fixed you can use the adjacent selector, e.g. if you only have three <li> elements, you can select the last <li> with:

#nav li+li+li {
    border-bottom: 1px solid #b5b5b5;
}

The question I would ask is, why are you including the extra columns in your DataTable if they aren't required?

Maybe you should modify your SQL select statement so that it is looking at the specific criteria you are looking for as you are populating your DataTable.

You could also use LINQ to query your DataTable as Enumerable and create a List Object that represents only certain columns.

Other than that, hide the DataGridView Columns that you don't require.

The two valid mains are int main() and int main(int, char*[]). Any thing else may or may not compile. If main doesn't explicitly return a value, 0 is implicitly returned.

With angular 6 and rxjs 6 Observable.throw(), Observable.off() has been deprecated instead you need to use throwError

ex :

return this.http.get('yoururl')
  .pipe(
    map(response => response.json()),
    catchError((e: any) =>{
      //do your processing here
      return throwError(e);
    }),
  );

In your composer.json, you can put:

{
    "require": {
        "vendor/package": "version"
    }
}

then run composer install or composer update from the directory containing composer.json. Sometimes, for me, composer is hinky, so I'll start with composer clear-cache; rm -rf vendor; rm composer.lock before composer install to make sure it's getting fresh stuff.

Of course, as the other answers point out you can run the following from the terminal:

composer require vendor/package:version

[a-zA-Z0-9] will only match ASCII characters, it won't match

String target = new String("A" + "\u00ea" + "\u00f1" +
                             "\u00fc" + "C");

If you also want to match unicode characters:

String pat = "^[\\p{L}0-9]*$";

A compiler consists of two major blocks: the 'front end' and the 'back end'. The front end of a compiler analyzes the source code and builds some form of a 'intermediary representation' of said source code which is much easier to analyze by a machine algorithm than is the source code (i.e. whereas the source code e.g. C++ is designed to help the human programmer to write code, the intermediary form is designed to help simplify the algorithm that analyzes said intermediary form easier). The back end of a compiler takes the intermediary form and then converts it to a 'target language'.

Now, the target language for general-use compilers are assembler languages for various processors, but there's nothing to prohibit a compiler back end to produce code in some other language, for as long as said target language is (at least) as flexible as a general CPU assembler.

Now, as you can probably imagine, C is definitely as flexible as a CPU's assembler, such that a C++ to C compiler is really no problem to implement from a technical pov.

So you have: C++ ---frontEnd---> someIntermediaryForm ---backEnd---> C

You may want to check these guys out: http://www.edg.com/index.php?location=c_frontend (the above link is just informative for what can be done, they license their front ends for tens of thousands of dollars)

PS As far as i know, there is no such a C++ to C compiler by GNU, and this totally beats me (if i'm right about this). Because the C language is fairly small and it's internal mechanisms are fairly rudimentary, a C compiler requires something like one man-year work (i can tell you this first hand cause i wrote such a compiler myself may years ago, and it produces a [virtual] stack machine intermediary code), and being able to have a maintained, up-to-date C++ compiler while only having to write a C compiler once would be a great thing to have...

Simplest code is DataGridView1.SelectedCells(column_index).Value

As an example, for the first selected cell:

DataGridView1.SelectedCells(0).Value

Edward,

You can modify the code in your example like this:

var playerShip:PlayerShip!
var deltaPoint = CGPointZero

init(size: CGSize)
{
    super.init(size: size)
    playerLayerNode.addChild(playerShip)        
}

This is using an implicitly unwrapped optional.

In documentation we can read:

"As with optionals, if you don’t provide an initial value when you declare an implicitly unwrapped optional variable or property, it’s value automatically defaults to nil."

If everything is contained in one file, there's the command gd (as in 'goto definition'), which will take you to the first occurrence in the file of the word under the cursor, which is often the definition.

Hello World!
You see, the main question while using hidden input is what kind of data you want to pass? I will assume that you are trying to pass the user ID.
Which is not a really good idea to pass it here because field() method will generate input and the value will be shown to user as we can't hide html from the users browser. This if you really care about security of your website.

please check this link, and you will see that it's impossible to hide value attribute from users to see.

so what to do then?

See, this is the core of OOP in PHP. and I quote from Matt Zandstr in his great book PHP Objects, Patterns, and Practice fifth edition

I am still stuck with a great deal of unwanted flexibility, though. I rely on the client coder to change a ShopProduct object’s properties from their default values. This is problematic in two ways. First, it takes five lines to properly initialize a ShopProduct object, and no coder will thank you for that. Second, I have no way of ensuring that any of the properties are set when a ShopProduct object is initialized. What I need is a method that is called automatically when an object is instantiated from a class.

Please check this example of using __construct() method which is mentioned in his book too.

     class ShopProduct { 
       public $title;   
       public $producerMainName;  
       public $producerFirstName;  
       public $price = 0;
    
       public function __construct($title,$firstName,$mainName,$price) {
            $this->title = $title;
            $this->producerFirstName = $firstName;  
            $this->producerMainName = $mainName; 
            $this->price = $price;
    }
 }
     

$product1 = new ShopProduct("My Antonia","Willa","Cather",5.99 );
print "author: {$product1->getProducer()}\n";

This produces the following:

author: Willa Cather

Class Car {
  private $user_id;
//.. your properties

  public function __construct($title,$firstName,$mainName,$price){
     $this->user_id = \Yii::$app->user->id;
    //..Your magic

   }
}

The error is pretty clear. The file hello.py is not an executable file. You need to specify the executable:

subprocess.call(['python.exe', 'hello.py', 'htmlfilename.htm'])

You'll need python.exe to be visible on the search path, or you could pass the full path to the executable file that is running the calling script:

import sys
subprocess.call([sys.executable, 'hello.py', 'htmlfilename.htm'])

Add this line in manifest : android:configChanges="orientation|screenSize"

Open the hosts file located at : **C:\windows\system32\drivers\etc**.

Hosts file is for what?

Add the following at end of this file :

YourServerIP YourDNS

Example:

198.168.1.1 maps.google.com

As Pax rightly said, measure, don't guess. That what I did for DNSwitness and the results were suprising: the ideal number of threads was much higher than I thought, something like 15,000 threads to get the fastest results.

Of course, it depends on many things, that's why you must measure yourself.

Complete measures (in French only) in Combien de fils d'exécution ?.

Your regular expression [^a-zA-Z0-9]\s/g says match any character that is not a number or letter followed by a space.

Remove the \s and you should get what you are after if you want a _ for every special character.

var newString = str.replace(/[^A-Z0-9]/ig, "_");

That will result in hello_world___hello_universe

If you want it to be single underscores use a + to match multiple

var newString = str.replace(/[^A-Z0-9]+/ig, "_");

That will result in hello_world_hello_universe

Just reboot your server, it will clear all current processes that have your database locked.

Just my 2 cents, hope it helps someone somewhere.

That's right. 'list index out of range' most likely means you are referring to n-th element of the list, while the length of the list is smaller than n.

Use content="IE=edge,chrome=1"   Skip other X-UA-Compatible modes

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

• No compatibility icon
  The IE9 Address bar does not show up the Compatibility View button
  and the page does not also show up a jumble of out-of-place menus, images, and text boxes.

• Features
  This meta tag is required to enable javascript::JSON.parse() on IE8
  (even when <!DOCTYPE html> is present)

• Correctness
  Rendering/Execution of modern HTML/CSS/JavaScript is more valid (nicer).

• Performance
  The Trident rendering engine should run faster in its edge mode.

Usage

In your HTML

<!DOCTYPE html> 
<html> 
  <head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

• IE=edge means IE should use the latest (edge) version of its rendering engine
• chrome=1 means IE should use the Chrome rendering engine if installed

Or better in the configuration of your web server:
(see also the RiaD's answer)

• Apache as proposed by pixeline

  <IfModule mod_setenvif.c>
    <IfModule mod_headers.c>
      BrowserMatch MSIE ie
      Header set X-UA-Compatible "IE=Edge,chrome=1" env=ie
    </IfModule>
  </IfModule>
  <IfModule mod_headers.c>
    Header append Vary User-Agent
  </IfModule>
  

• Nginx as proposed by Stef Pause

  server {
    #...
    add_header X-UA-Compatible "IE=Edge,chrome=1";
  }
  

• Varnish proxy as proposed by Lucas Riutzel

  sub vcl_deliver {
    if( resp.http.Content-Type ~ "text/html" ) {
      set resp.http.X-UA-Compatible = "IE=edge,chrome=1";
    }
  }
  

• IIS (since v7)

  <configuration>
    <system.webServer>
       <httpProtocol>
          <customHeaders>
             <add name="X-UA-Compatible" value="IE=edge,chrome=1" />
          </customHeaders>
       </httpProtocol>
    </system.webServer>
  </configuration>
  

Microsoft recommends Edge mode since IE11

As noticed by Lynda (see comments), the Compatibility changes in IE11 recommends Edge mode:

Starting with IE11, edge mode is the preferred document mode; it represents the highest support for modern standards available to the browser.

But the position of Microsoft was not clear. Another MSDN page did not recommend Edge mode:

Because Edge mode forces all pages to be opened in standards mode, regardless of the version of Internet Explorer, you might be tempted to use this for all pages viewed with Internet Explorer. Don't do this, as the X-UA-Compatible header is only supported starting with Windows Internet Explorer 8.

Instead, Microsoft recommended using <!DOCTYPE html>:

If you want all supported versions of Internet Explorer to open your pages in standards mode, use the HTML5 document type declaration [...]

As Ricardo explains (in the comments below) any DOCTYPE (HTML4, XHTML1...) can be used to trigger Standards Mode, not only HTML5's DOCTYPE. The important thing is to always have a DOCTYPE in the page.

Clara Onager has even noticed in an older version of Specifying legacy document modes:

Edge mode is intended for testing purposes only; do not use it in a production environment.

It is so confusing that Usman Y thought Clara Onager was speaking about:

The [...] example is provided for illustrative purposes only; don't use it in a production environment.

<meta http-equiv="X-UA-Compatible" content="IE=7,9,10" >

Well... In the rest of this answer I give more explanations why using content="IE=edge,chrome=1" is a good practice in production.

History

For many years (2000 to 2008), IE market share was more than 80%. And IE v6 was considered as a de facto standard (80% to 97% market share in 2003, 2004, 2005 and 2006 for IE6 only, more market share with all IE versions).

As IE6 was not respecting Web standards, developers had to test their website using IE6. That situation was great for Microsoft (MS) as web developers had to buy MS products (e.g. IE cannot be used without buying Windows), and it was more profit-making to stay non-compliant (i.e. Microsoft wanted to become the standard excluding other companies).

Therefore many many sites were IE6 compliant only, and as IE was not compliant with web standard, all these web sites was not well rendered on standards compliant browsers. Even worse, many sites required only IE.

However, at this time, Mozilla started Firefox development respecting as much as possible all the web standards (other browser were implemented to render pages as done by IE6). As more and more web developers wanted to use the new web standards features, more and more websites were more supported by Firefox than IE.

When IE market sharing was decreasing, MS realized staying standard incompatible was not a good idea. Therefore MS started to release new IE version (IE8/IE9/IE10) respecting more and more the web standards.

The web-incompatible issue

But the issue is all the websites designed for IE6: Microsoft could not release new IE versions incompatible with these old IE6-designed websites. Instead of deducing the IE version a website has been designed, MS requested developers to add extra data (X-UA-Compatible) in their pages.

IE6 is still used in 2016

Nowadays, IE6 is still used (0.7% in 2016) (4.5% in January 2014), and some internet websites are still IE6-only-compliant. Some intranet website/applications are tested using IE6. Some intranet website are 100% functional only on IE6. These companies/departments prefer to postpone the migration cost: other priorities, nobody no longer knows how the website/application has been implemented, the owner of the legacy website/application went bankrupt...

China represents 50% of IE6 usage in 2013, but it may change in the next years as Chinese Linux distribution is being broadcast.

Be confident with your web skills

If you (try to) respect web standard, you can simply always use http-equiv="X-UA-Compatible" content="IE=edge,chrome=1". To keep compatibility with old browsers, just avoid using latest web features: use the subset supported by the oldest browser you want to support. Or If you want to go further, you may adopt concepts as Graceful degradation, Progressive enhancement and Unobtrusive JavaScript. (You may also be pleased to read What should a web developer consider?.)

Do do not care about the best IE version rendering: this is not your job as browsers have to be compliant with web standards. If your site is standard compliant and use moderately latest features, therefore browsers have to be compliant with your website.

Moreover, as there are many campaigns to kill IE6 (IE6 no more, MS campaign), nowadays you may avoid wasting time with IE testing!

Personal IE6 experience

In 2009-2012, I worked for a company using IE6 as the official single browser allowed. I had to implement an intranet website for IE6 only. I decided to respect web standard but using the IE6-capable subset (HTML/CSS/JS).

It was hard, but when the company switched to IE8, the website was still well rendered because I had used Firefox and firebug to check the web-standard compatibility ;)

you can also use PHP short tag to make it shorter. here's an example

<a href="<?= site_url('controller/function'); ?>Contacts</a>

or use the built in anchor function of CI.

This is my sample code for rebuild url query string with JS

//function get current parameters_x000D_
$.urlParam = function(name){_x000D_
    var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);_x000D_
    if (results==null){_x000D_
        return null;_x000D_
    }_x000D_
    else{_x000D_
        return results[1] || 0;_x000D_
    }_x000D_
};_x000D_
_x000D_
//build a new parameters_x000D_
var param1 = $.urlParam('param1');_x000D_
var param2 = $.urlParam('param2');_x000D_
_x000D_
//check and create an array to save parameters_x000D_
var params = {};_x000D_
    if (param1 != null) {_x000D_
        params['param1'] = param1;_x000D_
    }_x000D_
    if (order != null) {_x000D_
        params['param2'] = param2;_x000D_
    }_x000D_
_x000D_
//build a new url with new parameters using jQuery param_x000D_
window.location.href =  window.location.origin + window.location.pathname + '?' + $.param(params);

I used JQUERY param: http://api.jquery.com/jquery.param/ to create a new url with new parameters.

How about:

>>> string_1 = "(555).555-5555"
>>> string_2 = "(555) 555 - 5555 ext. 5555"
>>> any(c.isalpha() for c in string_1)
False
>>> any(c.isalpha() for c in string_2)
True

A 404 return code actually means 'resource not found', and applies to any entity for which a request was made but not satisfied. So it works equally-well for pages, subsections of pages, and any item that exists on the page which has a specific request to be rendered.

So 404 is the right code to use in this scenario. Note that it doesn't apply to 'server not found', which is a different situation in which a request was issued but not answered at all, as opposed to answered but without the resource requested.

If you find by alphabet in plist, it should be "Application supports iTunes file sharing".

Support, unfortunately, is brutal at best. Here's a post on the topic:

https://www.campaignmonitor.com/blog/email-marketing/2013/02/embedded-images-in-html-email/

And the post content:

You can try in two ways. The detail is in this link.

1) Via pip

pip install --upgrade certifi

2) If it doesn't work, try to run a Cerificates.command that comes bundled with Python 3.* for Mac:(Go to your python installation location and double click the file)

open /Applications/Python\ 3.*/Install\ Certificates.command

Please also see this Microsoft Connect report on essentially, how blummin' difficult it is to use PowerShell to run shell commands (oh, the irony).

http://connect.microsoft.com/PowerShell/feedback/details/376207/

They suggest using --% as a way to force PowerShell to stop trying to interpret the text to the right.

For example:

MSBuild /t:Publish --% /p:TargetDatabaseName="MyDatabase";TargetConnectionString="Data Source=.\;Integrated Security=True" /p:SqlPublishProfilePath="Deploy.publish.xml" Database.sqlproj

sc queryex type= service state= all | find /i "NATION"

• use /i for case insensitive search
• the white space after type=is deliberate and required

Since R is already installed, you should be able to upgrade it with this method. First of all, you may want to have the packages you installed in the previous version in the new one,so it is convenient to check this post. Then, follow the instructions from here

1. Open the sources.list file:

    sudo nano /etc/apt/sources.list    
   

2. Add a line with the source from where the packages will be retrieved. For example:

    deb https://cloud.r-project.org/bin/linux/ubuntu/ version/
   

   Replace https://cloud.r-project.org with whatever mirror you would like to use, and replace version/ with whatever version of Ubuntu you are using (eg, trusty/, xenial/, and so on). If you're getting a "Malformed line error", check to see if you have a space between /ubuntu/ and version/.

3. Fetch the secure APT key:

    gpg --keyserver keyserver.ubuntu.com --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9
   

or

    gpg --hkp://keyserver keyserver.ubuntu.com:80 --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9

4. Add it to keyring:

    gpg -a --export E084DAB9 | sudo apt-key add -
   

5. Update your sources and upgrade your installation:

    sudo apt-get update && sudo apt-get upgrade
   

6. Install the new version

    sudo apt-get install r-base-dev
   

7. Recover your old packages following the solution that best suits to you (see this). For instance, to recover all the packages (not only those from CRAN) the idea is:

-- copy the packages from R-oldversion/library to R-newversion/library, (do not overwrite a package if it already exists in the new version!).

-- Run the R command update.packages(checkBuilt=TRUE, ask=FALSE).

How about something like this:

for (int row = 0; row < 3; row ++)
    for (int col = 0; col < 3; col++)
        table[row][col] = (char) ('1' + row * 3 + col);

The following complete Java program:

class Test {
    public static void main(String[] args) {
        char[][] table = new char[3][3];
        for (int row = 0; row < 3; row ++)
            for (int col = 0; col < 3; col++)
                table[row][col] = (char) ('1' + row * 3 + col);

        for (int row = 0; row < 3; row ++)
            for (int col = 0; col < 3; col++)
                System.out.println (table[row][col]);
    }
}

outputs:

1
2
3
4
5
6
7
8
9

This works because the digits in Unicode are consecutive starting at \u0030 (which is what you get from '0').

The expression '1' + row * 3 + col (where you vary row and col between 0 and 2 inclusive) simply gives you a character from 1 to 9.

Obviously, this won't give you the character 10 (since that's two characters) if you go further but it works just fine for the 3x3 case. You would have to change the method of generating the array contents at that point such as with something like:

String[][] table = new String[5][5];
for (int row = 0; row < 5; row ++)
    for (int col = 0; col < 5; col++)
        table[row][col] = String.format("%d", row * 5 + col + 1);

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

DatabaseUtils.queryNumEntries (since api:11) is useful alternative that negates the need for raw SQL(yay!).

SQLiteDatabase db = getReadableDatabase();
DatabaseUtils.queryNumEntries(db, "users",
                "uname=? AND pwd=?", new String[] {loginname,loginpass});

It sets result to the (unsigned) value resulting from putting the 8 bits of value in the lowest 8 bits of result.

The reason something like this is necessary is that byte is a signed type in Java. If you just wrote:

int result = value;

then result would end up with the value ff ff ff fe instead of 00 00 00 fe. A further subtlety is that the & is defined to operate only on int values¹, so what happens is:

1. value is promoted to an int (ff ff ff fe).
2. 0xff is an int literal (00 00 00 ff).
3. The & is applied to yield the desired value for result.

(The point is that conversion to int happens before the & operator is applied.)

1_{Well, not quite. The & operator works on long values as well, if either operand is a long. But not on byte. See the Java Language Specification, sections 15.22.1 and 5.6.2.}

Here is a list of some of the advantages of partial classes.

You can separate UI design code and business logic code so that it is easy to read and understand. For example you are developing an web application using Visual Studio and add a new web form then there are two source files, "aspx.cs" and "aspx.designer.cs" . These two files have the same class with the partial keyword. The ".aspx.cs" class has the business logic code while "aspx.designer.cs" has user interface control definition.

When working with automatically generated source, the code can be added to the class without having to recreate the source file. For example you are working with LINQ to SQL and create a DBML file. Now when you drag and drop a table it creates a partial class in designer.cs and all table columns have properties in the class. You need more columns in this table to bind on the UI grid but you don't want to add a new column to the database table so you can create a separate source file for this class that has a new property for that column and it will be a partial class. So that does affect the mapping between database table and DBML entity but you can easily get an extra field. It means you can write the code on your own without messing with the system generated code.

More than one developer can simultaneously write the code for the class.

You can maintain your application better by compacting large classes. Suppose you have a class that has multiple interfaces so you can create multiple source files depending on interface implements. It is easy to understand and maintain an interface implemented on which the source file has a partial class.

Extension to parse decimal number from string.

• No matter number will be on the beginning, in the end, or in the middle of a string.
• No matter if there will be only number or lot of "garbage" letters.
• No matter what is delimiter configured in the cultural settings on the PC: it will parse dot and comma both correctly.

• Ability to set decimal symbol manually.

  public static class StringExtension
  {
      public static double DoubleParseAdvanced(this string strToParse, char decimalSymbol = ',')
      {
          string tmp = Regex.Match(strToParse, @"([-]?[0-9]+)([\s])?([0-9]+)?[." + decimalSymbol + "]?([0-9 ]+)?([0-9]+)?").Value;
  
          if (tmp.Length > 0 && strToParse.Contains(tmp))
          {
              var currDecSeparator = System.Windows.Forms.Application.CurrentCulture.NumberFormat.NumberDecimalSeparator;
  
              tmp = tmp.Replace(".", currDecSeparator).Replace(decimalSymbol.ToString(), currDecSeparator);
  
              return double.Parse(tmp);
          }
  
          return 0;
      }
  }
  

How to use:

"It's 4.45 O'clock now".DoubleParseAdvanced(); // will return 4.45
"It's 4,45 O'clock now".DoubleParseAdvanced(); // will return 4.45
"It's 4:45 O'clock now".DoubleParseAdvanced(':'); // will return 4.45

i think the best solution is disabling with css. You define a new class and you turn off the mouse events on it:

.disabledTab{
    pointer-events: none;
}

And then you assign this class to the desired li element:

<li class="disabled disabledTab"><a href="#"> .... </a></li>

You can add/remove the class with jQuery also. For example, to disable all tabs:

$("ul.nav li").removeClass('active').addClass('disabledTab');

Here is an example: jsFiddle

I think you need a floor function :

math.floor(x)

To stop executing java code just use this command:

    System.exit(1);

After this command java stops immediately!

for example:

    int i = 5;
    if (i == 5) {
       System.out.println("All is fine...java programm executes without problem");
    } else {
       System.out.println("ERROR occured :::: java programm has stopped!!!");
       System.exit(1);
    }

It appears they do not want to support the syntax from ng1.

According to Miško Hevery (reference):

Maps have no orders in keys and hence they iteration is unpredictable. This was supported in ng1, but we think it was a mistake and will not be supported in NG2

The plan is to have a mapToIterable pipe

<div *ngFor"var item of map | mapToIterable">

So in order to iterate over your object you will need to use a "pipe". Currently there is no pipe implemented that does that.

As a workaround, here is a small example that iterates over the keys:

Component:

import {Component} from 'angular2/core';

@Component({
  selector: 'component',
  templateUrl: `
       <ul>
       <li *ngFor="#key of keys();">{{key}}:{{myDict[key]}}</li>
       </ul>
  `
})
export class Home {
  myDict : Dictionary;
  constructor() {
    this.myDict = {'key1':'value1','key2':'value2'};
  }

  keys() : Array<string> {
    return Object.keys(this.myDict);
  }
}

interface Dictionary {
    [ index: string ]: string
}

You have not used float:left command for your text.

Alternative syntax using the -Not operator and depending on your preference for readability:

if( -Not (Test-Path -Path $TARGETDIR ) )
{
    New-Item -ItemType directory -Path $TARGETDIR
}

Flipper isn't working on 0.61.x, so commenting out/removing initializeFlipper(this) in your MainApplication.java should do the trick.

Chill Pill.

i have experienced the same problem, and after reading this post i have double checked the JAVA_HOME definition in .bash_profile. It is actually:

export JAVA_HOME=$(which java)

that, exactly as Anony-Mousse is explaining, is the executable. Changing it to:

export=/Library/Java/Home

fixes the problem, tho is still interesting to understand why it's valued in that way in the profile file.

Though not POSIX, bash 4 has the &> operator:

command &> alloutput.txt

Below config worked for me. Refer this link for more details.

It's really easy to do with github pages, it's just a bit weird the first time you do it. Sorta like the first time you had to juggle 3 kittens while learning to knit. (OK, it's not all that bad)

You need a gh-pages branch:

Basically github.com looks for a gh-pages branch of the repository. It will serve all HTML pages it finds in here as normal HTML directly to the browser.

How do I get this gh-pages branch?

Easy. Just create a branch of your github repo called gh-pages. Specify --orphan when you create this branch, as you don't actually want to merge this branch back into your github branch, you just want a branch that contains your HTML resources.

$ git checkout --orphan gh-pages

What about all the other gunk in my repo, how does that fit in to it?

Nah, you can just go ahead and delete it. And it's safe to do now, because you've been paying attention and created an orphan branch which can't be merged back into your main branch and remove all your code.

I've created the branch, now what?

You need to push this branch up to github.com, so that their automation can kick in and start hosting these pages for you.

git push -u origin gh-pages

But.. My HTML is still not being served!

It takes a few minutes for github to index these branches and fire up the required infrastructure to serve up the content. Up to 10 minutes according to github.

The steps layed out by github.com

https://help.github.com/articles/creating-project-pages-manually

You may also simply write these string extension methods, and put them somewhere in your solution:

using System.Text;

public static class StringExtensions
{
    public static string ReplaceAll(this string original, string toBeReplaced, string newValue)
    {
        if (string.IsNullOrEmpty(original) || string.IsNullOrEmpty(toBeReplaced)) return original;
        if (newValue == null) newValue = string.Empty;
        StringBuilder sb = new StringBuilder();
        foreach (char ch in original)
        {
            if (toBeReplaced.IndexOf(ch) < 0) sb.Append(ch);
            else sb.Append(newValue);
        }
        return sb.ToString();
    }

    public static string ReplaceAll(this string original, string[] toBeReplaced, string newValue)
    {
        if (string.IsNullOrEmpty(original) || toBeReplaced == null || toBeReplaced.Length <= 0) return original;
        if (newValue == null) newValue = string.Empty;
        foreach (string str in toBeReplaced)
            if (!string.IsNullOrEmpty(str))
                original = original.Replace(str, newValue);
        return original;
    }
}

Call them like this:

"ABCDE".ReplaceAll("ACE", "xy");

xyBxyDxy

And this:

"ABCDEF".ReplaceAll(new string[] { "AB", "DE", "EF" }, "xy");

xyCxyF

Integer Types:

short            -> signed short
signed short
unsigned short
int              -> signed int
signed int
unsigned int
signed           -> signed int
unsigned         -> unsigned int
long             -> signed long
signed long
unsigned long

Be careful of char:

char  (is signed or unsigned depending on the implmentation)
signed char
unsigned char

And for SBT : excludeDependencies += "log4j" % "log4j"

An empty string has one single null byte. So test if (s[0] == (char)0)

Attention: This method saves the credentials in plaintext on your PC's disk. Everyone on your computer can access it, e.g. malicious NPM modules.

Run

git config --global credential.helper store

then

git pull

provide a username and password and those details will then be remembered later. The credentials are stored in a file on the disk, with the disk permissions of "just user readable/writable" but still in plaintext.

If you want to change the password later

git pull

Will fail, because the password is incorrect, git then removes the offending user+password from the ~/.git-credentials file, so now re-run

git pull

to provide a new password so it works as earlier.

#include <iostream>
std::cout << someString << "\n";

or

printf("%s\n",someString.c_str());

I also come across same problem, I changed transaction timeout to 15 minutes and it works. I hope this helps.

TransactionOptions options = new TransactionOptions();
options.IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted;
options.Timeout = new TimeSpan(0, 15, 0);
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required,options))
{
    sp1();
    sp2();
    ...

}

This is almost identical to how Karl Shifflet demonstrated a RelayCommand, where Execute fires a predetermined Action<T>. A top-notch solution, if you ask me.

public class RelayCommand : ICommand
{
    private readonly Predicate<object> _canExecute;
    private readonly Action<object> _execute;

    public RelayCommand(Predicate<object> canExecute, Action<object> execute)
    {
        _canExecute = canExecute;
        _execute = execute;
    }

    public event EventHandler CanExecuteChanged
    {
        add => CommandManager.RequerySuggested += value;
        remove => CommandManager.RequerySuggested -= value;
    }

    public bool CanExecute(object parameter)
    {
        return _canExecute(parameter);
    }

    public void Execute(object parameter)
    {
        _execute(parameter);
    }
}

This could then be used as...

public class MyViewModel
{
    private ICommand _doSomething;
    public ICommand DoSomethingCommand
    {
        get
        {
            if (_doSomething == null)
            {
                _doSomething = new RelayCommand(
                    p => this.CanDoSomething,
                    p => this.DoSomeImportantMethod());
            }
            return _doSomething;
        }
    }
}

Minimal runnable multi-file scope example

Here I illustrate how static affects the scope of function definitions across multiple files.

a.c

#include <stdio.h>

/* Undefined behavior: already defined in main.
 * Binutils 2.24 gives an error and refuses to link.
 * https://stackoverflow.com/questions/27667277/why-does-borland-compile-with-multiple-definitions-of-same-object-in-different-c
 */
/*void f() { puts("a f"); }*/

/* OK: only declared, not defined. Will use the one in main. */
void f(void);

/* OK: only visible to this file. */
static void sf() { puts("a sf"); }

void a() {
    f();
    sf();
}

main.c

#include <stdio.h>

void a(void);        

void f() { puts("main f"); }

static void sf() { puts("main sf"); }

void m() {
    f();
    sf();
}

int main() {
    m();
    a();
    return 0;
}

GitHub upstream.

Compile and run:

gcc -c a.c -o a.o
gcc -c main.c -o main.o
gcc -o main main.o a.o
./main

Output:

main f
main sf
main f
a sf

Interpretation

• there are two separate functions sf, one for each file
• there is a single shared function f

As usual, the smaller the scope, the better, so always declare functions static if you can.

In C programming, files are often used to represent "classes", and static functions represent "private" methods of the class.

A common C pattern is to pass a this struct around as the first "method" argument, which is basically what C++ does under the hood.

What standards say about it

C99 N1256 draft 6.7.1 "Storage-class specifiers" says that static is a "storage-class specifier".

6.2.2/3 "Linkages of identifiers" says static implies internal linkage:

If the declaration of a file scope identifier for an object or a function contains the storage-class specifier static, the identifier has internal linkage.

and 6.2.2/2 says that internal linkage behaves like in our example:

In the set of translation units and libraries that constitutes an entire program, each declaration of a particular identifier with external linkage denotes the same object or function. Within one translation unit, each declaration of an identifier with internal linkage denotes the same object or function.

where "translation unit" is a source file after preprocessing.

How GCC implements it for ELF (Linux)?

With the STB_LOCAL binding.

If we compile:

int f() { return 0; }
static int sf() { return 0; }

and disassemble the symbol table with:

readelf -s main.o

the output contains:

Num:    Value          Size Type    Bind   Vis      Ndx Name
  5: 000000000000000b    11 FUNC    LOCAL  DEFAULT    1 sf
  9: 0000000000000000    11 FUNC    GLOBAL DEFAULT    1 f

so the binding is the only significant difference between them. Value is just their offset into the .bss section, so we expect it to differ.

STB_LOCAL is documented on the ELF spec at http://www.sco.com/developers/gabi/2003-12-17/ch4.symtab.html:

STB_LOCAL Local symbols are not visible outside the object file containing their definition. Local symbols of the same name may exist in multiple files without interfering with each other

which makes it a perfect choice to represent static.

Functions without static are STB_GLOBAL, and the spec says:

When the link editor combines several relocatable object files, it does not allow multiple definitions of STB_GLOBAL symbols with the same name.

which is coherent with the link errors on multiple non static definitions.

If we crank up the optimization with -O3, the sf symbol is removed entirely from the symbol table: it cannot be used from outside anyways. TODO why keep static functions on the symbol table at all when there is no optimization? Can they be used for anything?

• Same for variables: https://stackoverflow.com/a/14339047/895245
• extern is the opposite of static, and functions are already extern by default: How do I use extern to share variables between source files?

C++ anonymous namespaces

In C++, you might want to use anonymous namespaces instead of static, which achieves a similar effect, but further hides type definitions: Unnamed/anonymous namespaces vs. static functions

Download it from here:

http://www.iis.net/downloads/microsoft/url-rewrite

or if you already have Web Platform Installer on your machine you can install it from there.

You can use jQuery's css function to test the CSS properties, eg. if ($('node').css('display') == 'block').

Colin is right, that there is no explicit event that gets fired when a specific CSS property gets changed. But you may be able to flip it around, and trigger an event that sets the display, and whatever else.

Also consider using adding CSS classes to get the behavior you want. Often you can add a class to a containing element, and use CSS to affect all elements. I often slap a class onto the body element to indicate that an AJAX response is pending. Then I can use CSS selectors to get the display I want.

Not sure if this is what you're looking for.

window.onload = function() {
    var el = document.documentElement,
        rfs = el.requestFullScreen
        || el.webkitRequestFullScreen
        || el.mozRequestFullScreen;
    rfs.call(el);
};

All work perfectly :)

 NSString *test = @"test";
 unichar a;
 int index = 5;
    
 @try {
    a = [test characterAtIndex:index];
 }
 @catch (NSException *exception) {
    NSLog(@"%@", exception.reason);
    NSLog(@"Char at index %d cannot be found", index);
    NSLog(@"Max index is: %lu", [test length] - 1);
 }
 @finally {
    NSLog(@"Finally condition");
 }

Log:

[__NSCFConstantString characterAtIndex:]: Range or index out of bounds

Char at index 5 cannot be found

Max index is: 3

Finally condition

I believe that although javascript is an option here, you have a smoother animation through forcing hardware accelerate with CSS3. You can achieve this by setting the following CSS3 properties on the moving div:

div.hardware-accelarate {
     -webkit-transform: translate3d(0,0,0);
        -moz-transform: translate3d(0,0,0);
         -ms-transform: translate3d(0,0,0);
          -o-transform: translate3d(0,0,0);
             transform: translate3d(0,0,0);
}

I've made a plunkr setup for ya'll to test and tweak...

I understand where the problem lies and when I look at the specs its clear that unescaped single quotes should be parsed correctly.

I am using jquery`s jQuery.parseJSON function to parse the JSON string but still getting the parse error when there is a single quote in the data that is prepared with json_encode.

Could it be a mistake in my implementation that looks like this (PHP - server side):

$data = array();

$elem = array();
$elem['name'] = 'Erik';
$elem['position'] = 'PHP Programmer';
$data[] = json_encode($elem);

$elem = array();
$elem['name'] = 'Carl';
$elem['position'] = 'C Programmer';
$data[] = json_encode($elem);

$jsonString = "[" . implode(", ", $data) . "]";

The final step is that I store the JSON encoded string into an JS variable:

<script type="text/javascript">
employees = jQuery.parseJSON('<?=$marker; ?>');
</script>

If I use "" instead of '' it still throws an error.

SOLUTION:

The only thing that worked for me was to use bitmask JSON_HEX_APOS to convert the single quotes like this:

json_encode($tmp, JSON_HEX_APOS);

Is there another way of tackle this issue? Is my code wrong or poorly written?

Thanks

Referring to Gamaliel 's answer: $args is an array of the arguments that are passed into a script at runtime - as such cannot be used the way Gamaliel is using it. This is actually working:

$myPath = 'C:\whatever.file'
# get actual Acl entry
$myAcl = Get-Acl "$myPath"
$myAclEntry = "Domain\User","FullControl","Allow"
$myAccessRule = New-Object System.Security.AccessControl.FileSystemAccessRule($myAclEntry)
# prepare new Acl
$myAcl.SetAccessRule($myAccessRule)
$myAcl | Set-Acl "$MyPath"
# check if added entry present
Get-Acl "$myPath" | fl

Another option, if portability is not your main concern, is to use associative arrays that are built in to the shell. This should work in bash 4.0 (available now on most major distros, though not on OS X unless you install it yourself), ksh, and zsh:

declare -A newmap
newmap[name]="Irfan Zulfiqar"
newmap[designation]=SSE
newmap[company]="My Own Company"

echo ${newmap[company]}
echo ${newmap[name]}

Depending on the shell, you may need to do a typeset -A newmap instead of declare -A newmap, or in some it may not be necessary at all.

GitHub has a new option relative to the preceding answers, just copy/paste the command lines from the PR:

1. Scroll to the bottom of the PR to see the Merge or Squash and merge button
2. Click the link on the right: view command line instructions
3. Press the Copy icon to the right of Step 1
4. Paste the commands in your terminal

use a StreamReader, then you can use the ReadToEnd method that returns a string.

This is my working example of our simple Vue component.

<template functional>
    <div v-html="require('!!html-loader!./../svg/logo.svg')"></div>
</template>

A single css code on hover can do the trick: box-shadow: inset 100px 0 0 0 #e0e0e0;

I'm not sure if you need source code. There is a free online JavaScript formatter at http://www.blackbeltcoder.com/Resources/JSFormatter.aspx.

Another option is to use InjectableValues and @JacksonInject. It is very useful if you need to use not always the same value but one get from DB or somewhere else for the specific case. Here is an example of using JacksonInject:

protected static class Some {
    private final String field1;
    private final String field2;

    public Some(@JsonProperty("field1") final String field1,
            @JsonProperty("field2") @JacksonInject(value = "defaultValueForField2",
                    useInput = OptBoolean.TRUE) final String field2) {
        this.field1 = requireNonNull(field1);
        this.field2 = requireNonNull(field2);
    }

    public String getField1() {
        return field1;
    }

    public String getField2() {
        return field2;
    }
}

@Test
public void testReadValueInjectables() throws JsonParseException, JsonMappingException, IOException {
    final ObjectMapper mapper = new ObjectMapper();
    final InjectableValues injectableValues =
            new InjectableValues.Std().addValue("defaultValueForField2", "somedefaultValue");
    mapper.setInjectableValues(injectableValues);

    final Some actualValueMissing = mapper.readValue("{\"field1\": \"field1value\"}", Some.class);
    assertEquals(actualValueMissing.getField1(), "field1value");
    assertEquals(actualValueMissing.getField2(), "somedefaultValue");

    final Some actualValuePresent =
            mapper.readValue("{\"field1\": \"field1value\", \"field2\": \"field2value\"}", Some.class);
    assertEquals(actualValuePresent.getField1(), "field1value");
    assertEquals(actualValuePresent.getField2(), "field2value");
}

Keep in mind that if you are using constructor to create the entity (this usually happens when you use @Value or @AllArgsConstructor in lombok ) and you put @JacksonInject not to the constructor but to the property it will not work as expected - value of the injected field will always override value in json, no matter whether you put useInput = OptBoolean.TRUE in @JacksonInject. This is because jackson injects those properties after constructor is called (even if the property is final) - field is set to the correct value in constructor but then it is overrided (check: https://github.com/FasterXML/jackson-databind/issues/2678 and https://github.com/rzwitserloot/lombok/issues/1528#issuecomment-607725333 for more information), this test is unfortunately passing:

protected static class Some {
    private final String field1;

    @JacksonInject(value = "defaultValueForField2", useInput = OptBoolean.TRUE)
    private final String field2;

    public Some(@JsonProperty("field1") final String field1,
            @JsonProperty("field2") @JacksonInject(value = "defaultValueForField2",
                    useInput = OptBoolean.TRUE) final String field2) {
        this.field1 = requireNonNull(field1);
        this.field2 = requireNonNull(field2);
    }

    public String getField1() {
        return field1;
    }

    public String getField2() {
        return field2;
    }
}

@Test
public void testReadValueInjectablesIncorrectBehavior() throws JsonParseException, JsonMappingException, IOException {
    final ObjectMapper mapper = new ObjectMapper();
    final InjectableValues injectableValues =
            new InjectableValues.Std().addValue("defaultValueForField2", "somedefaultValue");
    mapper.setInjectableValues(injectableValues);

    final Some actualValueMissing = mapper.readValue("{\"field1\": \"field1value\"}", Some.class);
    assertEquals(actualValueMissing.getField1(), "field1value");
    assertEquals(actualValueMissing.getField2(), "somedefaultValue");

    final Some actualValuePresent =
            mapper.readValue("{\"field1\": \"field1value\", \"field2\": \"field2value\"}", Some.class);
    assertEquals(actualValuePresent.getField1(), "field1value");
    // unfortunately "field2value" is overrided because of putting "@JacksonInject" to the field
    assertEquals(actualValuePresent.getField2(), "somedefaultValue");
}

Hope this helps to someone with a similar problem.

P.S. I'm using jackson v. 2.9.6

Assuming that your original dataset is similar to the one you created (i.e. with NA as character. You could specify na.strings while reading the data using read.table. But, I guess NAs would be detected automatically.

The price column is factor which needs to be converted to numeric class. When you use as.numeric, all the non-numeric elements (i.e. "NA", FALSE) gets coerced to NA) with a warning.

library(dplyr)
df %>%
     mutate(price=as.numeric(as.character(price))) %>%  
     group_by(company, year, product) %>%
     summarise(total.count=n(), 
               count=sum(is.na(price)), 
               avg.price=mean(price,na.rm=TRUE),
               max.price=max(price, na.rm=TRUE))

data

I am using the same dataset (except the ... row) that was showed.

df = tbl_df(data.frame(company=c("Acme", "Meca", "Emca", "Acme", "Meca","Emca"),
 year=c("2011", "2010", "2009", "2011", "2010", "2013"), product=c("Wrench", "Hammer",
 "Sonic Screwdriver", "Fairy Dust", "Kindness", "Helping Hand"), price=c("5.67",
 "7.12", "12.99", "10.99", "NA",FALSE)))

Run this script from SharePoint 2010 Management Shell as Administrator.

-(UIButton *)addButton:(NSString *)title :(CGRect)frame : (SEL)selector :(UIImage *)image :(int)tag{

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = frame;
[btn addTarget:self action:selector forControlEvents:UIControlEventTouchUpInside];
[btn setTitle:title forState:UIControlStateNormal];
[btn setImage:image forState:UIControlStateNormal];
btn.backgroundColor = [UIColor clearColor];
btn.tag = tag;

return btn;

}

and you can add it to the view:

[self.view addSubview:[self addButton:nil :self.view.frame :@selector(btnAction:) :[UIImage imageNamed:@"img.png"] :1]];

It isn't necessary. It's a quirk of the language.

This line:

if(str2==${str}){

Should be:

if( str2 == str ) {

The ${ and } will give you a parse error, as they should only be used inside Groovy Strings for templating

When submitting a form, you tell your browser to send, via the HTTP protocol, a message on the network, properly enveloped in a TCP/IP protocol message structure. An HTML page has a way to send data to the server: by using <form>s.

When a form is submitted, an HTTP Request is created and sent to the server, the message will contain the field names in the form and the values filled in by the user. This transmission can happen with POST or GET HTTP methods.

• POST tells your browser to build an HTTP message and put all content in the body of the message (a very useful way of doing things, more safe and also flexible).
• GET will submit the form data in the querystring. It has some constraints about data representation and length.

Stating how to send your form to the server

Attribute enctype has sense only when using POST method. When specified, it instructs the browser to send the form by encoding its content in a specific way. From MDN - Form enctype:

When the value of the method attribute is post, enctype is the MIME type of content that is used to submit the form to the server.

• application/x-www-form-urlencoded: This is the default. When the form is sent, all names and values are collected and URL Encoding is performed on the final string.
• multipart/form-data: Characters are NOT encoded. This is important when the form has a file upload control. You want to send the file binary and this ensures that bitstream is not altered.
• text/plain: Spaces get converted, but no more encoding is performed.

Security

When submitting forms, some security concerns can arise as stated in RFC 7578 Section 7: Multipart form data - Security considerations:

All form-processing software should treat user supplied form-data
with sensitivity, as it often contains confidential or personally
identifying information. There is widespread use of form "auto-fill" features in web browsers; these might be used to trick users to
unknowingly send confidential information when completing otherwise
innocuous tasks. multipart/form-data does not supply any features
for checking integrity, ensuring confidentiality, avoiding user
confusion, or other security features; those concerns must be
addressed by the form-filling and form-data-interpreting applications.

Applications that receive forms and process them must be careful not to supply data back to the requesting form-processing site that was not intended to be sent.

It is important when interpreting the filename of the Content-
Disposition header field to not inadvertently overwrite files in the
recipient's file space.

This concerns you if you are a developer and your server will process forms submitted by users which might end up containing sensitive information.

Here's a drop-in example that expands on Andreas Köberle's solution. It uses jQuery for the event handler and the document ready event, but those could be switched to plain JS:

(function(document, $) {

  $(function() {
    $(document).on('click', '[disable-on-click], .disable-on-click', function() {
      var disableText = this.getAttribute("data-disable-text") || 'Processing...';

      if(this.form) {
        this.form.submit();
      }

      this.disabled = true;

      if(this.tagName === 'BUTTON') {
        this.innerHTML = disableText;
      } else if(this.tagName === 'INPUT') {
        this.value = disableText;
      }
    });
  });

})(document, jQuery);

It can then be used in HTML like this:

<button disable-on-click data-disable-text="Saving...">Click Me</button>
<button class="disable-on-click">Click Me</button>
<input type="submit" disable-on-click value="Click Me" />

The location of jfxrt.jar in Oracle Java 7 is:

<JRE_HOME>/lib/jfxrt.jar

The location of jfxrt.jar in Oracle Java 8 is:

<JRE_HOME>/lib/ext/jfxrt.jar

The <JRE_HOME> will depend on where you installed the Oracle Java and may differ between Linux distributions and installations.

jfxrt.jar is not in the Linux OpenJDK 7 (which is what you are using).

An open source package which provides JavaFX 8 for Debian based systems such as Ubuntu is available. To install this package it is necessary to install both the Debian OpenJDK 8 package and the Debian OpenJFX package. I don't run Debian, so I'm not sure where the Debian OpenJFX package installs jfxrt.jar.

Use Oracle Java 8.

With Oracle Java 8, JavaFX is both included in the JDK and is on the default classpath. This means that JavaFX classes will automatically be found both by the compiler during the build and by the runtime when your users use your application. So using Oracle Java 8 is currently the best solution to your issue.

OpenJDK for Java 8 could include JavaFX (as JavaFX for Java 8 is now open source), but it will depend on the OpenJDK package assemblers as to whether they choose to include JavaFX 8 with their distributions. I hope they do, as it should help remove the confusion you experienced in your question and it also provides a great deal more functionality in OpenJDK.

My understanding is that although JavaFX has been included with the standard JDK since version JDK 7u6

Yes, but only the Oracle JDK.

The JavaFX version bundled with Java 7 was not completely open source so it could not be included in the OpenJDK (which is what you are using).

In you need to use Java 7 instead of Java 8, you could download the Oracle JDK for Java 7 and use that. Then JavaFX will be included with Java 7. Due to the way Oracle configured Java 7, JavaFX won't be on the classpath. If you use Java 7, you will need to add it to your classpath and use appropriate JavaFX packaging tools to allow your users to run your application. Some tools such as e(fx)clipse and NetBeans JavaFX project type will take care of classpath issues and packaging tasks for you.

In addition to the previous comments browser support for word-wrap seems to be a bit better than for word-break.

You can use bc (calculator). Assuming your file with #s is called "n":

$ cat n
1
2
3
$ (cat n | tr "\012" "+" ; echo "0") | bc 
6

The tr changes all newlines to "+"; then we append 0 after the last plus, then we pipe the expression (1+2+3+0) to the calculator

Or, if you are OK with using awk or perl, here's a Perl one-liner:

$perl -nle '$sum += $_ } END { print $sum' n
6

For PyTorch v1.0 and possibly above:

>>> import torch
>>> var = torch.tensor([[1,0], [0,1]])

# Using .size function, returns a torch.Size object.
>>> var.size()
torch.Size([2, 2])
>>> type(var.size())
<class 'torch.Size'>

# Similarly, using .shape
>>> var.shape
torch.Size([2, 2])
>>> type(var.shape)
<class 'torch.Size'>

You can cast any torch.Size object to a native Python list:

>>> list(var.size())
[2, 2]
>>> type(list(var.size()))
<class 'list'>

In PyTorch v0.3 and 0.4:

Simply list(var.size()), e.g.:

>>> import torch
>>> from torch.autograd import Variable
>>> from torch import IntTensor
>>> var = Variable(IntTensor([[1,0],[0,1]]))

>>> var
Variable containing:
 1  0
 0  1
[torch.IntTensor of size 2x2]

>>> var.size()
torch.Size([2, 2])

>>> list(var.size())
[2, 2]

Arrays.sort(yourList,new Comparator<YourObject>() {

    @Override
    public int compare(YourObjecto1, YourObjecto2) {
        return compare(o1.getYourColumn(), o2.getYourColumn());
    }
});

That might be because you would be using functional component and in that you would be using these '{}' braces instead of '()' Example : const Main = () => ( ... then your code ... ). Basically, you will have to wrap up your code within these brackets '()'.

int() is the Python standard built-in function to convert a string into an integer value. You call it with a string containing a number as the argument, and it returns the number converted to an integer:

>>> int("1") + 1
2

If you know the structure of your list, T1 (that it simply contains lists, only one level), you could do this in Python 3:

T2 = [list(map(int, x)) for x in T1]

In Python 2:

T2 = [map(int, x) for x in T1]

Truth values can be described using a Boolean algebra. The article also contains tables for and and or. This should help you to get started or to get even more confused.

I found one solution and it does not require to define runnable or other things and it's working fine.

    var lastTouchTime: Long = 0

    // ( ViewConfiguration.#.DEFAULT_LONG_PRESS_TIMEOUT =500)
    val longPressTime = 500

    var lastTouchX = 0f
    var lastTouchY = 0f

    view.setOnTouchListener { v, event ->

        when (event.action) {
            MotionEvent.ACTION_DOWN -> {
                lastTouchTime = SystemClock.elapsedRealtime()
                lastTouchX = event.x
                lastTouchY = event.y
                return@setOnTouchListener true
            }
            MotionEvent.ACTION_UP -> {
                if (SystemClock.elapsedRealtime() - lastTouchTime > longPressTime
                        && Math.abs(event.x - lastTouchX) < 3
                        && Math.abs(event.y - lastTouchY) < 3) {
                    Log.d(TAG, "Long press")
                }
                return@setOnTouchListener true
            }
            else -> {
                return@setOnTouchListener false
            }
        }

    }

You are echoing outside the body tag of your HTML. Put your echos there, and you should be fine.

Also, remove the onclick="alert()" from your submit. This is the cause for your first undefined message.

<?php
  $posted = false;
  if( $_POST ) {
    $posted = true;

    // Database stuff here...
    // $result = mysql_query( ... )
    $result = $_POST['name'] == "danny"; // Dummy result
  }
?>

<html>
  <head></head>
  <body>

  <?php
    if( $posted ) {
      if( $result ) 
        echo "<script type='text/javascript'>alert('submitted successfully!')</script>";
      else
        echo "<script type='text/javascript'>alert('failed!')</script>";
    }
  ?>
    <form action="" method="post">
      Name:<input type="text" id="name" name="name"/>
      <input type="submit" value="submit" name="submit"/>
    </form>
  </body>
</html>

The observation that the event had to be initiated by the user helped me to figure out the first part of this, but even after that Chrome and Firefox still blocked the new window. The second part was adding target="_blank" to the link, which was mentioned in one comment.

In summary: you need to call window.open from an event initiated by the user, in this case clicking on a link, and that link needs to have target="_blank".

In the example below the link is using class="button-twitter".

$('.button-twitter').click(function(e) {
  e.preventDefault();
  var href = $(this).attr('href');
  var tweet_popup = window.open(href, 'tweet_popup', 'width=500,height=300');
});

Yes, there seems some restrictions by some browser in SVG. The developertool restrict it to 8000px; The following dynamically generated Chart fails for example in Chrome.

Use the remove() method:

$(this).children("ul").remove();

I think that your two examples are actually only one: the free() should occur only at the end of the process, which as you point out is useless since the process is terminating.

In you second example though, the only difference is that you allow an undefined number of malloc(), which could lead to running out of memory. The only way to handle the situation is to check the return code of malloc() and act accordingly.

$('form button[type="submit"]').on('click', function () {
   $(this).parents('form').submit();
});

This worked for me in newer browsers:

autocomplete="new-password"

You cannot open and read a directory, use the isFile() and isDirectory() methods to distinguish between files and folders. You can get the contents of folders using the list() and listFiles() methods (for filenames and Files respectively) you can also specify a filter that selects a subset of files listed.

This is a way:

1. Using apktool to decode:

    $ apktool d -f {apkfile} -o {output folder}
   

2. Next, using JADX (at github.com/skylot/jadx)

    $ jadx -d {output folder} {apkfile}
   

2 tools extract and decompiler to same output folder.

Easy way: Using Online APK Decompiler

• https://apk.tools/tools/apk-decompiler/ (recommended)
• http://www.javadecompilers.com/apk

You can use the u option for jar

From the Java Tutorials:

jar uf jar-file input-file(s)

"Any files already in the archive having the same pathname as a file being added will be overwritten."

See Updating a JAR File.

Much better than making the whole jar all over again. Invoking this from within your program sounds possible too. Try Running Command Line in Java

you can get method parameter and its value and if annotated with a annotation with following code:

Map<String, Object> annotatedParameterValue = getAnnotatedParameterValue(MethodSignature.class.cast(jp.getSignature()).getMethod(), jp.getArgs()); ....

private Map<String, Object> getAnnotatedParameterValue(Method method, Object[] args) {
        Map<String, Object> annotatedParameters = new HashMap<>();
        Annotation[][] parameterAnnotations = method.getParameterAnnotations();
        Parameter[] parameters = method.getParameters();

        int i = 0;
        for (Annotation[] annotations : parameterAnnotations) {
            Object arg = args[i];
            String name = parameters[i++].getDeclaringExecutable().getName();
            for (Annotation annotation : annotations) {
                if (annotation instanceof AuditExpose) {
                    annotatedParameters.put(name, arg);
                }
            }
        }
        return annotatedParameters;
    }

First off:

public class ProfileCollection implements Iterable<Profile> {

Second:

return m_Profiles.get(m_ActiveProfile);

Yah I found

<base target="_parent" />

This useful for open all iframe links open in iframe.

And

$(window).load(function(){
    $("a").click(function(){
        top.window.location.href=$(this).attr("href");
        return true;
    })
})

This we can use for whole page or specific part of page.

Thanks all for your help.

And in Bash

 line1=`tail -3 /opt/Scripts/wowzaDataSync.log | grep "AmazonHttpClient" | head -1`
 vpid=`ps -ef|  grep wowzaDataSync | grep -v grep  | awk '{print $2}'`
 echo "-------->"${line1}
    if [ -z $line1 ] && [ ! -z $vpid ]
    then
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` :: 
            "Process Is Working Fine"
    else
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` :: 
            "Prcess Hanging Due To Exception With PID :"${pid}
   fi

OR in Bash

line1=`tail -3 /opt/Scripts/wowzaDataSync.log | grep "AmazonHttpClient" | head -1`
vpid=`ps -ef|  grep wowzaDataSync | grep -v grep  | awk '{print $2}'`
echo "-------->"${line1}
   if [ -z $line1 ] || [ ! -z $vpid ]
    then
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` :: 
            "Process Is Working Fine"
    else
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` :: 
            "Prcess Hanging Due To Exception With PID :"${pid}
  fi

For me the issue was that I used the connection string generated by ADO.Net Model (.edmx). Changing the connection string solved my issue.

the file is being opened and not closed for each call to the function also

The @Url.Action() method is proccess on the server-side, so you cannot pass a client-side value to this function as a parameter. You can concat the client-side variables with the server-side url generated by this method, which is a string on the output. Try something like this:

var firstname = "abc";
var username = "abcd";
location.href = '@Url.Action("Display", "Customer")?uname=' + firstname + '&name=' + username;

The @Url.Action("Display", "Customer") is processed on the server-side and the rest of the string is processed on the client-side, concatenating the result of the server-side method with the client-side.

You can do the following:

  public class Numbers {
    private int number1 = 50;
    private int number2 = 100;
    private List<Integer> list;

    public Numbers() {
      list = new ArrayList<Integer>();
      list.add(number1);
      list.add(number2);
    }

    int getNumber(int pos)
    {
      return list.get(pos);
    }
  }

  public class Test {
    private Numbers numbers;

    public Test(){
      numbers = new Numbers();
      int number1 = numbers.getNumber(0);
      int number2 = numbers.getNumber(1);
    }
  }

Ok so this one works. Just in case anybody wants it, here's the version that works for me :)

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Base64;


public class HttpBasicAuth {

    public static void main(String[] args) {

        try {
            URL url = new URL ("http://ip:port/login");
            String encoding = Base64.getEncoder().encodeToString(("test1:test1").getBytes(?"UTF??-8"?));

            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);
            connection.setRequestProperty  ("Authorization", "Basic " + encoding);
            InputStream content = (InputStream)connection.getInputStream();
            BufferedReader in   = 
                new BufferedReader (new InputStreamReader (content));
            String line;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
        } catch(Exception e) {
            e.printStackTrace();
        }

    }

}

I've been there too and searched everywhere how /usr/libexec/java_home works but I couldn't find any information on how it determines the available Java Virtual Machines it lists.

I've experimented a bit and I think it simply executes a ls /Library/Java/JavaVirtualMachines and then inspects the ./<version>/Contents/Info.plist of all runtimes it finds there.

It then sorts them descending by the key JVMVersion contained in the Info.plist and by default it uses the first entry as its default JVM.

I think the only thing we might do is to change the plist: sudo vi /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Info.plist and then modify the JVMVersion from 1.8.0 to something else that makes it sort it to the bottom instead of the top, like !1.8.0.

Something like:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    ...
    <dict>
            ...
            <key>JVMVersion</key>
            <string>!1.8.0</string>   <!-- changed from '1.8.0' to '!1.8.0' -->`

and then it magically disappears from the top of the list:

/usr/libexec/java_home -verbose
Matching Java Virtual Machines (3):
    1.7.0_45, x86_64:   "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home
    1.7.0_09, x86_64:   "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home
    !1.8.0, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home

Now you will need to logout/login and then:

java -version
java version "1.7.0_45"

:-)

Of course I have no idea if something else breaks now or if the 1.8.0-ea version of java still works correctly.

You probably should not do any of this but instead simply deinstall 1.8.0.

However so far this has worked for me.

DECLARE @id INT 
SET @id = 0 
UPDATE DESTINATAIRE_TEMP
SET @id = CODE_DEST = @id + 1 
GO 

try this

http://www.mssqltips.com/sqlservertip/1467/populate-a-sql-server-column-with-a-sequential-number-not-using-an-identity/

var myCheckboxes = new Array();
$("input:checked").each(function() {
   data['myCheckboxes[]'].push($(this).val());
});

You are pushing checkboxes to wrong array data['myCheckboxes[]'] instead of myCheckboxes.push

Another way to look at it is to consider git rebase master as:

Rebase the current branch on top of master

Here , 'master' is the upstream branch, and that explain why, during a rebase, ours and theirs are reversed.

Try This code:

public class GenericCompare<T> : IEqualityComparer<T> where T : class
{
    private Func<T, object> _expr { get; set; }
    public GenericCompare(Func<T, object> expr)
    {
        this._expr = expr;
    }
    public bool Equals(T x, T y)
    {
        var first = _expr.Invoke(x);
        var sec = _expr.Invoke(y);
        if (first != null && first.Equals(sec))
            return true;
        else
            return false;
    }
    public int GetHashCode(T obj)
    {
        return obj.GetHashCode();
    }
}

Example of its use would be

collection = collection
    .Except(ExistedDataEles, new GenericCompare<DataEle>(x=>x.Id))
    .ToList(); 

Just complementing what Donal Fellows said, you can use List with @RequestParam

public String controllerMethod(@RequestParam(value="myParam") List<ObjectToParse> myParam){
....
}

Hope it helps!

Django's class based views provide a generic FormView but for all intents and purposes it is designed to only handle one form.

One way to handle multiple forms with same target action url using Django's generic views is to extend the 'TemplateView' as shown below; I use this approach often enough that I have made it into an Eclipse IDE template.

class NegotiationGroupMultifacetedView(TemplateView):
    ### TemplateResponseMixin
    template_name = 'offers/offer_detail.html'

    ### ContextMixin 
    def get_context_data(self, **kwargs):
        """ Adds extra content to our template """
        context = super(NegotiationGroupDetailView, self).get_context_data(**kwargs)

        ...

        context['negotiation_bid_form'] = NegotiationBidForm(
            prefix='NegotiationBidForm', 
            ...
            # Multiple 'submit' button paths should be handled in form's .save()/clean()
            data = self.request.POST if bool(set(['NegotiationBidForm-submit-counter-bid',
                                              'NegotiationBidForm-submit-approve-bid',
                                              'NegotiationBidForm-submit-decline-further-bids']).intersection(
                                                    self.request.POST)) else None,
            )
        context['offer_attachment_form'] = NegotiationAttachmentForm(
            prefix='NegotiationAttachment', 
            ...
            data = self.request.POST if 'NegotiationAttachment-submit' in self.request.POST else None,
            files = self.request.FILES if 'NegotiationAttachment-submit' in self.request.POST else None
            )
        context['offer_contact_form'] = NegotiationContactForm()
        return context

    ### NegotiationGroupDetailView 
    def post(self, request, *args, **kwargs):
        context = self.get_context_data(**kwargs)

        if context['negotiation_bid_form'].is_valid():
            instance = context['negotiation_bid_form'].save()
            messages.success(request, 'Your offer bid #{0} has been submitted.'.format(instance.pk))
        elif context['offer_attachment_form'].is_valid():
            instance = context['offer_attachment_form'].save()
            messages.success(request, 'Your offer attachment #{0} has been submitted.'.format(instance.pk))
                # advise of any errors

        else 
            messages.error('Error(s) encountered during form processing, please review below and re-submit')

        return self.render_to_response(context)

The html template is to the following effect:

...

<form id='offer_negotiation_form' class="content-form" action='./' enctype="multipart/form-data" method="post" accept-charset="utf-8">
    {% csrf_token %}
    {{ negotiation_bid_form.as_p }}
    ...
    <input type="submit" name="{{ negotiation_bid_form.prefix }}-submit-counter-bid" 
    title="Submit a counter bid"
    value="Counter Bid" />
</form>

...

<form id='offer-attachment-form' class="content-form" action='./' enctype="multipart/form-data" method="post" accept-charset="utf-8">
    {% csrf_token %}
    {{ offer_attachment_form.as_p }}

    <input name="{{ offer_attachment_form.prefix }}-submit" type="submit" value="Submit" />
</form>

...

Our solution was to run

fastlane match

as I forgot we setup a Matchfile.

Character varying is different than text. Try running

ALTER TABLE product_product ALTER COLUMN code TYPE text;

That will change the column type to text, which is limited to some very large amount of data (you would probably never actually hit it.)

IDLE's console does not support ANSI escape sequences, or any other form of escapes for coloring your output.

You can learn how to talk to IDLE's console directly instead of just treating it like normal stdout and printing to it (which is how it does things like color-coding your syntax), but that's pretty complicated. The idle documentation just tells you the basics of using IDLE itself, and its idlelib library has no documentation (well, there is a single line of documentation—"(New in 2.3) Support library for the IDLE development environment."—if you know where to find it, but that isn't very helpful). So, you need to either read the source, or do a whole lot of trial and error, to even get started.

Alternatively, you can run your script from the command line instead of from IDLE, in which case you can use whatever escape sequences your terminal handles. Most modern terminals will handle at least basic 16/8-color ANSI. Many will handle 16/16, or the expanded xterm-256 color sequences, or even full 24-bit colors. (I believe gnome-terminal is the default for Ubuntu, and in its default configuration it will handle xterm-256, but that's really a question for SuperUser or AskUbuntu.)

Learning to read the termcap entries to know which codes to enter is complicated… but if you only care about a single console—or are willing to just assume "almost everything handles basic 16/8-color ANSI, and anything that doesn't, I don't care about", you can ignore that part and just hardcode them based on, e.g., this page.

Once you know what you want to emit, it's just a matter of putting the codes in the strings before printing them.

But there are libraries that can make this all easier for you. One really nice library, which comes built in with Python, is curses. This lets you take over the terminal and do a full-screen GUI, with colors and spinning cursors and anything else you want. It is a little heavy-weight for simple uses, of course. Other libraries can be found by searching PyPI, as usual.

try using cfg4py:

1. Hierarchichal design, mulitiple env supported, so never mess up dev settings with production site settings.
2. Code completion. Cfg4py will convert your yaml into a python class, then code completion is available while you typing your code.
3. many more..

Instead of storing the output of grep in a variable and then checking whether the variable is empty, you can do this:

if grep -q "poet" $file_name
then
    echo "poet was found in $file_name"
fi

============

Here are some commonly used tests:

   -d FILE
          FILE exists and is a directory
   -e FILE
          FILE exists
   -f FILE
          FILE exists and is a regular file
   -h FILE
          FILE exists and is a symbolic link (same as -L)
   -r FILE
          FILE exists and is readable
   -s FILE
          FILE exists and has a size greater than zero
   -w FILE
          FILE exists and is writable
   -x FILE
          FILE exists and is executable
   -z STRING
          the length of STRING is zero

Example:

if [ -e "$file_name" ] && [ ! -z "$used_var" ]
then
    echo "$file_name exists and $used_var is not empty"
fi

@Stebra See this example. This may help you.

public class CustomerInfo 
{   
    @SerializedName("customerid")
    public String customerid;
    @SerializedName("picture")
    public String picture;

    @SerializedName("location")
    public String location;

    public CustomerInfo()
    {}
}

And when you get the result; parse like this

List<CustomerInfo> customers = null;
customers = (List<CustomerInfo>)gson.fromJson(result, new TypeToken<List<CustomerInfo>>() {}.getType());

This example demonstrates the difference between the mousemove, mouseenter and mouseover events:

https://jsfiddle.net/z8g613yd/

HTML:

<div onmousemove="myMoveFunction()">
    <p>onmousemove: <br> <span id="demo">Mouse over me!</span></p>
</div>

<div onmouseenter="myEnterFunction()">
    <p>onmouseenter: <br> <span id="demo2">Mouse over me!</span></p>
</div>

<div onmouseover="myOverFunction()">
    <p>onmouseover: <br> <span id="demo3">Mouse over me!</span></p>
</div>

CSS:

div {
    width: 200px;
    height: 100px;
    border: 1px solid black;
    margin: 10px;
    float: left;
    padding: 30px;
    text-align: center;
    background-color: lightgray;
}

p {
    background-color: white;
    height: 50px;
}

p span {
    background-color: #86fcd4;
    padding: 0 20px;
}

JS:

var x = 0;
var y = 0;
var z = 0;

function myMoveFunction() {
    document.getElementById("demo").innerHTML = z += 1;
}

function myEnterFunction() {
    document.getElementById("demo2").innerHTML = x += 1;
}

function myOverFunction() {
    document.getElementById("demo3").innerHTML = y += 1;
}

• onmousemove : occurs every time the mouse pointer is moved over the div element.
• onmouseenter : only occurs when the mouse pointer enters the div element.
• onmouseover : occurs when the mouse pointer enters the div element, and its child elements (p and span).

Typically with Angular you would be outputting these spans using the ngRepeat directive and (like in your case) each item would have an id. I know this is not true for all situations but it is typical if requesting data from a backend - objects in an array tend to have unique identifiers.

You can use this id to facilitate the toggling of classes on items in your list (see plunkr or code below).

Using the objects id's can also eliminate the undesirable effect when the $index (described in other answers) is messed up due to sorting in Angular.

Example Plunkr: http://plnkr.co/edit/na0gUec6cdMABK9L6drV

(basically apply the .active-selection class if the person.id is equal to $scope.activeClass - which we set when the user clicks an item.

Hope this helps someone, I've found expressions in ng-class to be very useful!

HTML

<ul>
  <li ng-repeat="person in people" 
  data-ng-class="{'active-selection': person.id == activeClass}">
    <a data-ng-click="selectPerson(person.id)">
      {{person.name}}
    </a>
  </li>
</ul>

JS

app.controller('MainCtrl', function($scope) {
  $scope.people = [{
    id: "1",
    name: "John",
  }, {
    id: "2",
    name: "Lucy"
  }, {
    id: "3",
    name: "Mark"
  }, {
    id: "4",
    name: "Sam"
  }];

  $scope.selectPerson = function(id) {
    $scope.activeClass = id;
    console.log(id);
  };
});    

CSS:

.active-selection {
  background-color: #eee;
}

You could follow a solution similar to "How do I force “git pull” to overwrite local files?":

git fetch --all
git reset --hard origin/abranch
git checkout $branch 

That would involve only one fetch.

With Git 2.23+, git checkout is replaced here with git switch (presented here) (still experimental).

git switch -f $branch

(with -f being an alias for --discard-changes, as noted in Jan's answer)

Proceed even if the index or the working tree differs from HEAD.
Both the index and working tree are restored to match the switching target.

Yes it is possible if you bind events using tag attribute onclick="sayHi()" directly in template similar like your <body onload="start()"> - this approach similar to frameworks angular/vue/react/etc. You can also use <template> to operate on 'dynamic' html like here. It is not strict unobtrusive js however it is acceptable for small projects

function start() {_x000D_
  mydiv.innerHTML += "bar";_x000D_
}_x000D_
_x000D_
function sayHi() {_x000D_
  alert("hi");_x000D_
}

<body onload="start()">_x000D_
  <div id="mydiv" style="border: solid red 2px">_x000D_
    <span id="myspan" onclick="sayHi()">foo</span>_x000D_
  </div>_x000D_
</body>

This may be off topic, but for those who are struggling on how to exactly change also the font of the button text (that was my case and Skatephone's answer helped me) here's how I did it (if you made buttons ind design mode):

First we need to have the button's string name "converted" (it's a foul way to explain, but straightforward) into java from the xml, and so we paste the aforementioned code into our MainActivity.java

IMPORTANT! place the code under the OnCreate method!

import android.widget.RemoteViews;

RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.my_layout);
remoteViews.setTextViewText(R.id.Counter, "Set button text here");

Keep in mind:

my_layout has to be substituted with the xml file where your buttons are

Counter has to be substituted with the id name of your button ("@+id/ButtonName")

if you want to change the button text just insert the text in place of "Set button text here"

here comes the part where you change the font:

Now that you "converted" from xml to java, you can set a Typeface method for TextView. Paste the following code exactly under the previous one just described above

TextView txt = (TextView) findViewById(R.id.text_your_text_view_id);
        Typeface font = Typeface.createFromAsset(getAssets(), "fonts/MyFontName.ttf");
        txt.setTypeface(font);

where in place of text_your_text_view_id you put your button's id name (like as previous code) and in place of MyFontName.ttf you put your desired font

WARNING! This assumes you already put your desired font into the assets/font folder. e.g. assets/fonts/MyFontName.ttf

Add display: block; and overflow: auto; to .my-table. This will simply cut off anything past the 280px limit you enforced. There's no way to make it "look pretty" with that requirement due to words like pélagosthrough which are wider than 280px.

For functional components try useEffect with props.location.

import React, {useEffect} from 'react';

const SampleComponent = (props) => {

      useEffect(() => {
        console.log(props.location);
      }, [props.location]);

}

export default SampleComponent;

If your UML modeling tool has support for specifying an Enumeration, you should use that. It will likely be easier to do and it will give your model stronger semantics. Visually the result will be very similar to a Class with an <<enumeration>> Stereotype, but in the UML metamodel, an Enumeration is actually a separate (meta)type.

+---------------------+
|   <<enumeration>>   |
|    DayOfTheWeek     |
|_____________________|
| Sunday              |
| Monday              |
| Tuesday             |
| ...                 |
+---------------------+

Once it is defined, you can use it as the type of an Attribute just like you would a Datatype or the name one of your own Classes.

+---------------------+
|        Event        |
|_____________________|
| day : DayOfTheWeek  |
| ...                 |
+---------------------+

If you're using ArgoEclipse or ArgoUML, there's a pulldown menu on the toolbar which selects among Datatype, Enumeration, Signal, etc that will allow you to create your own Enumerations. The compartment that normally contains Attributes can then be populated with EnumerationLiterals for the values of your enumeration.

Here's a picture of a slightly different example in ArgoUML:

The easiest way that I could find to pass a message from my app to facebook was programmatically copy to the clipboard and alert the user that they have the option to paste. It saves the user from manually doing it; my app is not pasting but the user might.

...
if (app.equals("facebook")) {
    // overcome fb 'putExtra' constraint;
    // copy message to clipboard for user to paste into fb.
    ClipboardManager cb = (ClipboardManager) 
            getSystemService(Context.CLIPBOARD_SERVICE);
    ClipData clip = ClipData.newPlainText("post", msg);
    cb.setPrimaryClip(clip);

    // tell the to PASTE POST with option to stop showing this dialogue
    showDialog(this, getString(R.string.facebook_post));
}
startActivity(appIntent);
...

another workaround:

var myarray = [];
$("#test").click(function() {
    myarray[index]=$("#drop").val();
    alert(myarray);
});

i wanted to add all checked checkbox to array. so example, if .each is used:

var vpp = [];
var incr=0;
$('.prsn').each(function(idx) {
   if (this.checked) {
       var p=$('.pp').eq(idx).val();
       vpp[incr]=(p);
       incr++;
   }
});
//do what ever with vpp array;

The algorithm you have suggested will indeed find the shortest path in this graph, but not all graphs in general. For example, consider this graph:

Let's trace through the execution of your algorithm.

1. First, you set d(A) to 0 and the other distances to 8.
2. You then expand out node A, setting d(B) to 1, d(C) to 0, and d(D) to 99.
3. Next, you expand out C, with no net changes.
4. You then expand out B, which has no effect.
5. Finally, you expand D, which changes d(B) to -201.

Notice that at the end of this, though, that d(C) is still 0, even though the shortest path to C has length -200. This means that your algorithm doesn't compute the correct distances to all the nodes. Moreover, even if you were to store back pointers saying how to get from each node to the start node A, you'd end taking the wrong path back from C to A.

The reason for this is that Dijkstra's algorithm (and your algorithm) are greedy algorithms that assume that once they've computed the distance to some node, the distance found must be the optimal distance. In other words, the algorithm doesn't allow itself to take the distance of a node it has expanded and change what that distance is. In the case of negative edges, your algorithm, and Dijkstra's algorithm, can be "surprised" by seeing a negative-cost edge that would indeed decrease the cost of the best path from the starting node to some other node.

Hope this helps!

Presume he's using the tutorial from http://www.arcsynthesis.org/gltut/ along with premake4.3 :-)

After which I could build glsdk_0.4.4 and examples without further issue.

You can do it that way:

• Create a directory where you want to install composer (let's say /home/your_username/composer)
• Go to this directory - cd /home/your_username/composer

• Then run the following command:

  php -r "readfile('https://getcomposer.org/installer');" | php

• After that if you want to run composer, you can do it this way (in this caseyou must be in the composer's dir): php composer.phar

• As a next step, you can do this:

  alias composer="/home/your_username/composer/composer.phar".

  And run commands like you do it normally: $ composer install

Hope that helps

The === is not for checking string equalit , to do so you can use the Regxp functions for example

if (x.match(y) === null) {
// x and y are not equal 
}

there is also the test function

I just made this for my app :

public static Date getDatePart(Date dateTime) {
    TimeZone tz = TimeZone.getDefault();
    long rawOffset=tz.getRawOffset();
    long dst=(tz.inDaylightTime(dateTime)?tz.getDSTSavings():0);
    long dt=dateTime.getTime()+rawOffset+dst; // add offseet and dst to dateTime
    long modDt=dt % (60*60*24*1000) ;

    return new Date( dt
                    - modDt // substract the rest of the division by a day in milliseconds
                    - rawOffset // substract the time offset (Paris = GMT +1h for example)
                    - dst // If dayLight, substract hours (Paris = +1h in dayLight)
    );
}

Android API level 1, no external library. It respects daylight and default timeZone. No String manipulation so I think this way is more CPU efficient than yours but I haven't made any tests.

On mac, press Command + R or got to Database -> Reverse Engineer and keep selecting your requirements and continue

I'll add 2 points:

• "IN" is effectively serial ORs with parentheses around them
• AND has precedence over OR in every language I know

So, the 2 expressions are simply not equal.

WHERE some_col in (1,2,3,4,5) AND some_other_expr
--to the optimiser is this
WHERE
     (
     some_col = 1 OR
     some_col = 2 OR 
     some_col = 3 OR 
     some_col = 4 OR 
     some_col = 5
     )
     AND
     some_other_expr

So, when you break the IN clause up, you split the serial ORs up, and changed precedence.

If you have a .nupkg file and just need the .dll file all you have to do is change the extension to .zip and find the lib directory.

As it is not stated anywhere in the current answers, the fastest solution if you are not embedding js into your template is:

Put <script type="text/javascript"> window.CSRF_TOKEN = "{{ csrf_token }}"; </script> before your reference to script.js file in your template, then add csrfmiddlewaretoken into your data dictionary in your js file:

$.ajax({
            type: 'POST',
            url: somepathname + "do_it/",
            data: {csrfmiddlewaretoken: window.CSRF_TOKEN},
            success: function() {
                console.log("Success!");
            }
        })

If you are working in a browser that doesn't support tabindex="-1", you may be able to get away with just giving the things that need to be skipped a really high tab index. For example tabindex="500" basically moves the object's tab order to the end of the page.

I did this for a long data entry form with a button thrown in the middle of it. It's not a button people click very often so I didn't want them to accidentally tab to it and press enter. disabled wouldn't work because it's a button.

Neither is a good way to check for valid input.

• isset() is not sufficient because – as has been noted already – it considers an empty string to be a valid value.
• ! empty() is not sufficient either because it rejects '0', which could be a valid value.

Using isset() combined with an equality check against an empty string is the bare minimum that you need to verify that an incoming parameter has a value without creating false negatives:

if( isset($_GET['gender']) and ($_GET['gender'] != '') )
{
  ...
}

But by "bare minimum", I mean exactly that. All the above code does is determine whether there is some value for $_GET['gender']. It does not determine whether the value for $_GET['gender'] is valid (e.g., one of ("Male", "Female","FileNotFound")).

For that, see Josh Davis's answer.

Your class shoud look something like this:

class Something {     int[] array; //global array, replace type of course     void function1() {        array = new int[10]; //let say you declare it here that will be 10 integers in size     }     void function2() {        array[0] = 12; //assing value at index 0 to 12.     } } 

That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.

If you are generating Notification from a Service that is started in the foreground using

startForeground(NOTIFICATION_ID, notificationBuilder.build());

Then issuing

notificationManager.cancel(NOTIFICATION_ID);

does't work canceling the Notification & notification still appears in the status bar. In this particular case, you will solve these by 2 ways:

1> Using stopForeground( false ) inside service:

stopForeground( false );
notificationManager.cancel(NOTIFICATION_ID);

2> Destroy that service class with calling activity:

Intent i = new Intent(context, Service.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
if(ServiceCallingActivity.activity != null) {
    ServiceCallingActivity.activity.finish();
}
context.stopService(i);

Second way prefer in music player notification more because thay way not only notification remove but remove player also...!!

I have tried and get output after end task IDE from task manager. Later clean all temporary files from your drive. Start your IDE. Now your .exe working good.

create view sampleView as 
select field1, field2, ... 
from dbo.MyTableValueFunction

Note that even if your MyTableValueFunction doesn't accept any parameters, you still need to include parentheses after it, i.e.:

... from dbo.MyTableValueFunction()

Without the parentheses, you'll get an "Invalid object name" error.

Here is a simple, compact and easy to understand method I use.
First, add a service in your js.

app.factory('Helpers', [ function() {
      // Helper service body

        var o = {
        Helpers: []

        };

        // Dummy function with parameter being passed
        o.getFooBar = function(para) {

            var valueIneed = para + " " + "World!";

            return valueIneed;

          };

        // Other helper functions can be added here ...

        // And we return the helper object ...
        return o;

    }]);

Then, in your controller, inject your helper object and use any available function with something like the following:

app.controller('MainCtrl', [

'$scope',
'Helpers',

function($scope, Helpers){

    $scope.sayIt = Helpers.getFooBar("Hello");
    console.log($scope.sayIt);

}]);

Another way brackets and parentheses differ is that square brackets can describe a list comprehension, e.g. [x for x in y]

Whereas the corresponding parenthetic syntax specifies a tuple generator: (x for x in y)

You can get a tuple comprehension using: tuple(x for x in y)

See: Why is there no tuple comprehension in Python?

To make an input readonly use:

 $("#fieldName").attr('readonly','readonly');

to make it read/write use:

$("#fieldName").removeAttr('readonly');

adding the disabled attribute won't send the value with post.

For Windows Vista and Windows 7 you need to get the Remote Server Administration Tools (RSAT) - the Active Directory Users & Computers Snap-In is included in that pack. Download link: Remote Server Administration Tools for Windows 7.

<script>
var deg = 0

function rotate(id)
{
    deg = deg+45;
    var txt = 'rotate('+deg+'deg)';
    $('#'+id).css('-webkit-transform',txt);
}
</script>

What I do is something very easy... declare a global variable at the start... and then increment the variable however much I like, and use .css of jquery to increment.

Here's one more alternative:

var classElements = document.getElementsByClassName("className");

function setClassHeight (classElements, desiredHeightValue) 
    {
        var arrayElements = Object.entries(classElements);
        for(var i = 0; i< arrayElements.length; i++) {
            arrayElements[i][1].style.height = desiredHeightValue;
        }

    }

The correct shortcut is CTRL-R-W like you don't have to release CTRL button while pressing W. This worked for me in VS 2015

Try creating a symlink, make sure you have openssl installed in /usr/local/include first.

ln -s /usr/local/Cellar/openssl/{version}/include/openssl /usr/local/include/openssl

I scoured the internet for an updated (past year) answer using the latest location pulling methods suggested by google (to use FusedLocationProviderClient). I finally landed on this:

https://github.com/googlesamples/android-play-location/tree/master/LocationUpdates

I created a new project and copied in most of this code. Boom. It works. And I think without any deprecated lines.

Also, the simulator doesn't seem to get a GPS location, that I know of. It did get as far as reporting this in the log: "All location settings are satisfied."

And finally, in case you wanted to know (I did), you DO NOT need a google maps api key from the google developer console, if all you want is the GPS location.

Also useful is their tutorial. But I wanted a full one page tutorial/code example, and that. Their tutorial stacks but is confusing when you're new to this because you don't know what pieces you need from earlier pages.

https://developer.android.com/training/location/index.html

And finally, remember things like this:

I not only had to modify the mainActivity.Java. I also had to modify Strings.xml, androidmanifest.xml, AND the correct build.gradle. And also your activity_Main.xml (but that part was easy for me).

I needed to add dependencies like this one: implementation 'com.google.android.gms:play-services-location:11.8.0', and update the settings of my android studio SDK to include google play services. (file settings appearance system settings android SDK SDK Tools check google play services).

update: the android simulator did seem to get a location and location change events (when I changed the value in the settings of the sim). But my best and first results were on an actual device. So it's probably easiest to test on actual devices.

REST is a specific way of approaching the design of big systems (like the web).

It's a set of 'rules' (or 'constraints').

HTTP is a protocol that tries to obey those rules.

For anyone interested: if you are using Intellj, just simply put hibernate.cfg.xml under src/main/resources.

Solution posted by Cawas works perfectly with XCode4, too. However, there are some changes to IDE's UI, so you need to make some research to find Run Script :)

In the Project Navigator view click the root item of the project, then in the middle window select Target, then click Build Phases tab and at the bottom you'll see Add Build Phase button, click and select Add Run Script, then paste "codesign" script posted by Cawas.

This post has already a very good answer by "Community wiki" and I also recommend to look at Rick Strahl's Web Blog, there are many good posts about WCF Rest like this.

I used both to get this kind of MyService-service... Then I can use the REST-interface from jQuery or SOAP from Java.

This is from my Web.Config:

<system.serviceModel>
 <services>
  <service name="MyService" behaviorConfiguration="MyServiceBehavior">
   <endpoint name="rest" address="" binding="webHttpBinding" contract="MyService" behaviorConfiguration="restBehavior"/>
   <endpoint name="mex" address="mex" binding="mexHttpBinding" contract="MyService"/>
   <endpoint name="soap" address="soap" binding="basicHttpBinding" contract="MyService"/>
  </service>
 </services>
 <behaviors>
  <serviceBehaviors>
   <behavior name="MyServiceBehavior">
    <serviceMetadata httpGetEnabled="true"/>
    <serviceDebug includeExceptionDetailInFaults="true" />
   </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
   <behavior name="restBehavior">
    <webHttp/>
   </behavior>
  </endpointBehaviors>
 </behaviors>
</system.serviceModel>

And this is my service-class (.svc-codebehind, no interfaces required):

    /// <summary> MyService documentation here ;) </summary>
[ServiceContract(Name = "MyService", Namespace = "http://myservice/", SessionMode = SessionMode.NotAllowed)]
//[ServiceKnownType(typeof (IList<MyDataContractTypes>))]
[ServiceBehavior(Name = "MyService", Namespace = "http://myservice/")]
public class MyService
{
    [OperationContract(Name = "MyResource1")]
    [WebGet(ResponseFormat = WebMessageFormat.Xml, UriTemplate = "MyXmlResource/{key}")]
    public string MyResource1(string key)
    {
        return "Test: " + key;
    }

    [OperationContract(Name = "MyResource2")]
    [WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "MyJsonResource/{key}")]
    public string MyResource2(string key)
    {
        return "Test: " + key;
    }
}

Actually I use only Json or Xml but those both are here for a demo purpose. Those are GET-requests to get data. To insert data I would use method with attributes:

[OperationContract(Name = "MyResourceSave")]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, UriTemplate = "MyJsonResource")]
public string MyResourceSave(string thing){
    //...

#include <iostream>
#include <type_traits>

using namespace std;

enum class A {
  a = 1,
  b = 69,
  c= 666
};

std::ostream& operator << (std::ostream& os, const A& obj)
{
   os << static_cast<std::underlying_type<A>::type>(obj);
   return os;
}

int main () {
  A a = A::c;
  cout << a << endl;
}

Add the following css to disable the default scroll:

body {
    overflow: hidden;
}

And change the #content css to this to make the scroll only on content body:

#content {
    max-height: calc(100% - 120px);
    overflow-y: scroll;
    padding: 0px 10%;
    margin-top: 60px;
}

See fiddle here.

Edit:

Actually, I'm not sure what was the issue you were facing, since it seems that your css is working. I have only added the HTML and the header css statement:

html {_x000D_
  height: 100%;_x000D_

I had this problem and it was caused by the second level cache:

1. I persisted an entity using hibernate
2. Then I deleted the row created from a separate process that didn't interact with the second level cache
3. I persisted another entity with the same identifier (my identifier values are not auto-generated)

Hence, because the cache wasn't invalidated, hibernate assumed that it was dealing with a detached instance of the same entity.

In code level also, you could add your lib to the project using the compiler directives #pragma.

example:

#pragma comment( lib, "yourLibrary.lib" )

The options are the same as for the fopen function in the C standard library:

w truncates the file, overwriting whatever was already there

a appends to the file, adding onto whatever was already there

w+ opens for reading and writing, truncating the file but also allowing you to read back what's been written to the file

a+ opens for appending and reading, allowing you both to append to the file and also read its contents

No need to create custom template for MVC 4. Use TextBox instead of EditFor here special html attributes are not supported, it is only supported from MVC 5. TextBox is should support for MVC 4, I don't know about other version.

@Html.TextBox("test", "", new { @id = "signupform", @class = "form-control", @role = "form",@placeholder="Name" })

Yes, if you really want / need to do it you can use PowerMock. This should be considered a last resort. With PowerMock you can cause it to return a mock from the call to the constructor. Then do the verify on the mock. That said, csturtz's is the "right" answer.

Here is the link to Mock construction of new objects

Couldn't add this as a comment, but in case anyone is interested in using the accepted answer with subplots, the divider should be formed on specific axes object (rather than on the numpy.ndarray returned from plt.subplots)

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
data = np.arange(100, 0, -1).reshape(10, 10)
fig, ax = plt.subplots(ncols=2, nrows=2)
for row in ax:
    for col in row:
        im = col.imshow(data, cmap='bone')
        divider = make_axes_locatable(col)
        cax = divider.append_axes('right', size='5%', pad=0.05)
        fig.colorbar(im, cax=cax, orientation='vertical')
plt.show()

I think you should do

for index, row in result: 

If you wanna access by name.

Although Xotic750's answer provides several good points and possible solutions, sometimes simple is better.

You know the array being iterated on is being mutated in the iteration itself (i.e. removing an item => index changes), thus the simplest logic is to go backwards in an old fashioned for (à la C language):

let arr = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];_x000D_
_x000D_
for (let i = arr.length - 1; i >= 0; i--) {_x000D_
  if (arr[i] === 'a') {_x000D_
    arr.splice(i, 1);_x000D_
  }_x000D_
}_x000D_
_x000D_
document.body.append(arr.join());

If you really think about it, a forEach is just syntactic sugar for a for loop... So if it's not helping you, just please stop breaking your head against it.

You also need add these lines in PostgreSQL and restart the server:

log_directory = 'pg_log'                    
log_filename = 'postgresql-dateformat.log'
log_statement = 'all'
logging_collector = on

A better solution would be using Kendo ui draw dom to export to pdf-

Suppose the following html file which contains the canvas tag:

<script src="http://kendo.cdn.telerik.com/2017.2.621/js/kendo.all.min.js"></script>

    <script type="x/kendo-template" id="page-template">
     <div class="page-template">
            <div class="header">

            </div>
            <div class="footer" style="text-align: center">

                <h2> #:pageNum# </h2>
            </div>
      </div>
    </script>
    <canvas id="myCanvas" width="500" height="500"></canvas>
    <button onclick="ExportPdf()">download</button>

Now after that in your script write down the following and it will be done:

function ExportPdf(){ 
kendo.drawing
    .drawDOM("#myCanvas", 
    { 
        forcePageBreak: ".page-break", 
        paperSize: "A4",
        margin: { top: "1cm", bottom: "1cm" },
        scale: 0.8,
        height: 500, 
        template: $("#page-template").html(),
        keepTogether: ".prevent-split"
    })
        .then(function(group){
        kendo.drawing.pdf.saveAs(group, "Exported_Itinerary.pdf")
    });
}

And that is it, Write anything in that canvas and simply press that download button all exported into PDF. Here is a link to Kendo UI - http://docs.telerik.com/kendo-ui/framework/drawing/drawing-dom And a blog to better understand the whole process - https://www.cronj.com/blog/export-htmlcss-pdf-using-javascript/

Discussing nested classes...

The difference is that a nested class declaration that is also static can be instantiated outside of the enclosing class.

When you have a nested class declaration that is not static, Java won't let you instantiate it except via the enclosing class. The object created out of the inner class is linked to the object created from the outer class, so the inner class can reference the fields of the outer.

But if it's static, then the link does not exist, the outer fields cannot be accessed (except via an ordinary reference like any other object) and you can therefore instantiate the nested class by itself.

For column types Rails supports out of the box - like the string in this question - the best approach is to set the column default in the database itself as Daniel Kristensen indicates. Rails will introspect on the DB and initialize the object accordingly. Plus, that makes your DB safe from somebody adding a row outside of your Rails app and forgetting to initialize that column.

For column types Rails doesn't support out of the box - e.g. ENUM columns - Rails won't be able to introspect the column default. For these cases you do not want to use after_initialize (it is called every time an object is loaded from the DB as well as every time an object is created using .new), before_create (because it occurs after validation), or before_save (because it occurs upon update too, which is usually not what you want).

Rather, you want to set the attribute in a before_validation on: create, like so:

before_validation :set_status_because_rails_cannot, on: :create

def set_status_because_rails_cannot
  self.status ||= 'P'
end

use this one:

DecimalFormat form = new DecimalFormat("0.00");
etToll.setText(form.format(tvTotalAmount) );

Note: Data must be in decimal format (tvTotalAmount)

Before dealing with the iterables and iterator the major factor that decide the iterable and iterator is sequence

Sequence: Sequence is the collection of data

Iterable: Iterable are the sequence type object that support __iter__ method.

Iter method: Iter method take sequence as an input and create an object which is known as iterator

Iterator: Iterator are the object which call next method and transverse through the sequence. On calling the next method it returns the object that it traversed currently.

example:

x=[1,2,3,4]

x is a sequence which consists of collection of data

y=iter(x)

On calling iter(x) it returns a iterator only when the x object has iter method otherwise it raise an exception.If it returns iterator then y is assign like this:

y=[1,2,3,4]

As y is a iterator hence it support next() method

On calling next method it returns the individual elements of the list one by one.

After returning the last element of the sequence if we again call the next method it raise an StopIteration error

example:

>>> y.next()
1
>>> y.next()
2
>>> y.next()
3
>>> y.next()
4
>>> y.next()
StopIteration

$('#userid').change(function(){
  //fire your ajax call  
});

$('#userid').val(10).change();

You can do it in two lines, fully in a batch file, by writing the string to a file and then getting the length of the file. You just have to subtract two bytes to account for the automatic CR+LF added to the end.

Let's say your string is in a variable called strvar:

ECHO %strvar%> tempfile.txt
FOR %%? IN (tempfile.txt) DO ( SET /A strlength=%%~z? - 2 )

The length of the string is now in a variable called strlength.

In slightly more detail:

• FOR %%? IN (filename) DO ( ... : gets info about a file
• SET /A [variable]=[expression] : evaluate the expression numerically
• %%~z? : Special expression to get the length of the file

To mash the whole command in one line:

ECHO %strvar%>x&FOR %%? IN (x) DO SET /A strlength=%%~z? - 2&del x

You need a development provisioning profile on your build machine. Apps can run on the simulator without a profile, but they are required to run on an actual device.

If you open the project in Xcode, it may automatically set up provisioning for you. Otherwise you will have to create go to the iOS Dev Center and create a profile.

If you need one single regex, try:

(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\W)

A short explanation:

(?=.*[a-z])        // use positive look ahead to see if at least one lower case letter exists
(?=.*[A-Z])        // use positive look ahead to see if at least one upper case letter exists
(?=.*\d)           // use positive look ahead to see if at least one digit exists
(?=.*\W])        // use positive look ahead to see if at least one non-word character exists

And I agree with SilentGhost, \W might be a bit broad. I'd replace it with a character set like this: [-+_!@#$%^&*.,?] (feel free to add more of course!)

NSString *string = [NSString stringWithUTF8String:[Data bytes]];

I have to point that out as a lot of people can struggle into that without knowing the problem.

If you want the kb to hide when clicking Done, and you set android:imeOptions="actionDone" & android:maxLines="1" without setting your EditText inputType it will NOT work as the default inputType for the EditText is not "text" as a lot of people think.

so, setting only inputType will give you the results you desire whatever what you are setting it to like "text", "number", ...etc.

Along with the embed, I also had to install the Google Cast extension in my browser.

<iframe width="1280" height="720" src="https://www.youtube.com/embed/4u856utdR94" frameborder="0" allowfullscreen></iframe>

If you do it programmatically in JS it will be like reinventing the wheel. I recommend using a jQuery plugin called jGrowl

Just Add scrolling="no" and seamless="seamless" attributes to iframe tag. like this:-

 1. XHTML => scrolling="no"
 2. HTML5 => seamless="seamless"

UPDATE:

seamless attribute has been removed in all major browsers

MAMP & MAMP PRO 4.0.6 was starting MySql server correctly but stopped doing so after my machine updated the OS to macOS Sierra (10.12.2). I tried a few options mentioned here including setting folder permissions and re-install etc. Nothing seemed fixed the issue for me so I shifted to XAMPP and it is serving OK so far.

Update: I've got MAMP working with this simple solution here.

As noted, this is a recursion problem. In particular, you may want to look at

listFiles() 

In the java File API here. It returns an array of all the files in a directory. Using this along with

isDirectory()

to see if you need to recurse further is a good start.

Looking at the internets there can be various of causes. In my case leaving everything default except...

apc.shm_size = 64M

...cleared the countless warnings that I was getting earlier.

You could try to do this with getcode() from urllib

>>> print urllib.urlopen("http://www.stackoverflow.com").getcode()
>>> 200

EDIT: For more modern python, i.e. python3, use:

import urllib.request
print(urllib.request.urlopen("http://www.stackoverflow.com").getcode())
>>> 200

printStackTrace() helps the programmer to understand where the actual problem occurred. printStacktrace() is a method of the class Throwable of java.lang package. It prints several lines in the output console. The first line consists of several strings. It contains the name of the Throwable sub-class & the package information. From second line onwards, it describes the error position/line number beginning with at.

The last line always describes the destination affected by the error/exception. The second last line informs us about the next line in the stack where the control goes after getting transfer from the line number described in the last line. The errors/exceptions represents the output in the form a stack, which were fed into the stack by fillInStackTrace() method of Throwable class, which itself fills in the program control transfer details into the execution stack. The lines starting with at, are nothing but the values of the execution stack. In this way the programmer can understand where in code the actual problem is.

Along with the printStackTrace() method, it's a good idea to use e.getmessage().

You can use .is(':visible')

Selects all elements that are visible.

For example:

if($('#selectDiv').is(':visible')){

Also, you can get the div which is visible by:

$('div:visible').callYourFunction();

Live example:

console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));

#selectDiv {_x000D_
  display: none;  _x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>

An alternative to cat() is writeLines():

> writeLines("File not supplied.\nUsage: ./program F=filename")
File not supplied.
Usage: ./program F=filename
>

An advantage is that you don't have to remember to append a "\n" to the string passed to cat() to get a newline after your message. E.g. compare the above to the same cat() output:

> cat("File not supplied.\nUsage: ./program F=filename")
File not supplied.
Usage: ./program F=filename>

and

> cat("File not supplied.\nUsage: ./program F=filename","\n")
File not supplied.
Usage: ./program F=filename
>

The reason print() doesn't do what you want is that print() shows you a version of the object from the R level - in this case it is a character string. You need to use other functions like cat() and writeLines() to display the string. I say "a version" because precision may be reduced in printed numerics, and the printed object may be augmented with extra information, for example.

Change

android:useLevel="false"

to

android:useLevel="true"

for second sahpe with id="@android:id/progress

hope it works

To be precise, a block ends when it encounter a non-empty line indented at most the same level with the start. This non empty line is not part of that block For example, the following print ends two blocks at the same time:

def foo():
    if bar:
        print "bar"

print "baz" # ends the if and foo at the same time

The indentation level is less-than-or-equal to both the def and the if, hence it ends them both.

Lines with no statement, no matter the indentation, does not matter

def foo():
    print "The line below has no indentation"

    print "Still part of foo"

But the statement that marks the end of the block must be indented at the same level as any existing indentation. The following, then, is an error:

def foo():
    print "Still correct"
   print "Error because there is no block at this indentation"

Generally, if you're used to curly braces language, just indent the code like them and you'll be fine.

BTW, the "standard" way of indenting is with spaces only, but of course tab only is possible, but please don't mix them both.
