Programs & Examples On #Symbol capture

According to this code golfing solution by Gaffi, the following works:

a = Split(StrConv(s, 64), Chr(0))

May be it will helpful:

<Border BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Left" Height="160" Margin="10,55,0,0" VerticalAlignment="Top" Width="492"/>

If you want rollback data, firstly you need to execute autocommit =0 and then execute query delete, insert, or update.

After executing the query then execute rollback...

What I've done on my side:

Went to the /usr/local/lib/node_modules, and deleted the yarn folder inside it.

Setting of TAGs is really useful when you have a ListView and want to recycle/reuse the views. In that way the ListView is becoming very similar to the newer RecyclerView.

@Override
public View getView(int position, View convertView, ViewGroup parent)
  {
ViewHolder holder = null;

if ( convertView == null )
{
    /* There is no view at this position, we create a new one. 
       In this case by inflating an xml layout */
    convertView = mInflater.inflate(R.layout.listview_item, null);  
    holder = new ViewHolder();
    holder.toggleOk = (ToggleButton) convertView.findViewById( R.id.togOk );
    convertView.setTag (holder);
}
else
{
    /* We recycle a View that already exists */
    holder = (ViewHolder) convertView.getTag ();
}

// Once we have a reference to the View we are returning, we set its values.

// Here is where you should set the ToggleButton value for this item!!!

holder.toggleOk.setChecked( mToggles.get( position ) );

return convertView;
}

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

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

Use res.download()

It transfers the file at path as an “attachment”. For instance:

var express = require('express');
var router = express.Router();

// ...

router.get('/:id/download', function (req, res, next) {
    var filePath = "/my/file/path/..."; // Or format the path using the `id` rest param
    var fileName = "report.pdf"; // The default name the browser will use

    res.download(filePath, fileName);    
});

• Read more about res.download()

For running it on any CPU either 62 bit or 32 bit follow these steps: Right click on the name of the project in Solution Explorer> Properties>Build and have these under Configuration: Active(Release), Platform:Active(Any CPU) and Target:x86. and just beside the Run button Select option Release and Any CPU from the options. And then Save it and Run.

Here is a repo the demonstrates serving a custom font with Rails 5.2 that works on Heroku. It goes further and optimizes serving the fonts to be as fast as possible according to https://www.webpagetest.org/

https://github.com/nzoschke/edgecors

To start I picked pieces from answers above. For Rails 5.2+ you shouldn't need extra asset pipeline config.

Asset Pipeline and SCSS

• Place fonts in app/assets/fonts
• Place the @font-face declaration in an scss file and use the font-url helper

From app/assets/stylesheets/welcome.scss:

@font-face {
  font-family: 'Inconsolata';
  src: font-url('Inconsolata-Regular.ttf') format('truetype');
  font-weight: normal;
  font-style: normal;
}

body {
  font-family: "Inconsolata";
  font-weight: bold;
}

Serve from CDN with CORS

I'm using CloudFront, added with the Heroku Edge addon.

First configure a CDN prefix and default Cache-Control headers in production.rb:

Rails.application.configure do
  # e.g. https://d1unsc88mkka3m.cloudfront.net
  config.action_controller.asset_host = ENV["EDGE_URL"]

  config.public_file_server.headers = {
    'Cache-Control' => 'public, max-age=31536000'
  }
end

If you try to access the font from the herokuapp.com URL to the CDN URL, you will get a CORS error in your browser:

Access to font at 'https://d1unsc88mkka3m.cloudfront.net/assets/Inconsolata-Regular.ttf' from origin 'https://edgecors.herokuapp.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. edgecors.herokuapp.com/ GET https://d1unsc88mkka3m.cloudfront.net/assets/Inconsolata-Regular.ttf net::ERR_FAILED

So configure CORS to allow access to the font from Heroku to the CDN URL:

module EdgeCors
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.2

    config.middleware.insert_after ActionDispatch::Static, Rack::Deflater

    config.middleware.insert_before 0, Rack::Cors do
      allow do
        origins %w[
          http://edgecors.herokuapp.com
          https://edgecors.herokuapp.com
        ]
        resource "*", headers: :any, methods: [:get, :post, :options]
      end
    end
  end
end

Serve gzip Font Asset

The asset pipeline builds a .ttf.gz file but doesn't serve it. This monkey patch changes the asset pipeline gzip whitelist to a blacklist:

require 'action_dispatch/middleware/static'

ActionDispatch::FileHandler.class_eval do
  private

    def gzip_file_path(path)
      return false if ['image/png', 'image/jpeg', 'image/gif'].include? content_type(path)
      gzip_path = "#{path}.gz"
      if File.exist?(File.join(@root, ::Rack::Utils.unescape_path(gzip_path)))
        gzip_path
      else
        false
      end
    end
end

The ultimate result is a custom font file in app/assets/fonts served from a long-lived CloudFront cache.

This should work:

s=json.dumps(variables)
variables2=json.loads(s)
assert(variables==variables2)

why not just pass an data an object with your key/value pairs then you don't have to worry about encoding

$.ajax({
    type: "Post",
    url: "getdata.php",
    data:{
       timestamp: timestamp,
       uid: id,
       uname: name
    },
    async: true,
    cache: false,
    success: function(data) {


    };
}?);?

if (strstr(request, "favicon") != NULL) {
    // contains
}

You can also use map:

a = [1, 1, 1, 1, 1]
b = 1
list(map(lambda x: x + b, a))

It gives:

[2, 2, 2, 2, 2]

Use empty(). It checks for both empty strings and null.

if (!empty($_POST['user'])) {
  // do stuff
}

From the manual:

The following things are considered to be empty:

"" (an empty string)  
0 (0 as an integer)  
0.0 (0 as a float)  
"0" (0 as a string)    
NULL  
FALSE  
array() (an empty array)  
var $var; (a variable declared, but without a value in a class)  

I wasn't able to ever accomplish this but rather used view html source apps available on the Play Store to simply look for the element.

You should specially have a look on your global or static data (long living data).

When this data grows without restriction, you can also get troubles in Python.

The garbage collector can only collect data, that is not referenced any more. But your static data can hookup data elements that should be freed.

Another problem can be memory cycles, but at least in theory the Garbage collector should find and eliminate cycles -- at least as long as they are not hooked on some long living data.

What kinds of long living data are specially troublesome? Have a good look on any lists and dictionaries -- they can grow without any limit. In dictionaries you might even don't see the trouble coming since when you access dicts, the number of keys in the dictionary might not be of big visibility to you ...

static and class both associate a method with a class, rather than an instance of a class. The difference is that subclasses can override class methods; they cannot override static methods.

class properties will theoretically function in the same way (subclasses can override them), but they're not possible in Swift yet.

This can be done as follows :

select CONVERT(VARCHAR(10), GETDATE(), 103) + ' '  + convert(VARCHAR(8), GETDATE(), 14)

Hope it helps

Two arrays can be easily added or union without chaning their original indexing by + operator. This will be very help full in laravel and codeigniter select dropdown.

 $empty_option = array(
         ''=>'Select Option'
          );

 $option_list = array(
          1=>'Red',
          2=>'White',
          3=>'Green',
         );

  $arr_option = $empty_option + $option_list;

Output will be :

$arr_option = array(
   ''=>'Select Option'
   1=>'Red',
   2=>'White',
   3=>'Green',
 );

Documentation from npm for npm install <package-name> --save and npm install <package-name> --save-dev can be found here:

https://docs.npmjs.com/getting-started/using-a-package.json#the-save-and-save-dev-install-flags

A package.json file declares metadata about the module you are developing. Both aforementioned commands modify this package.json file. --save will declare the installed package (in this case, grunt) as a dependency for your module; --save-dev will declare it as a dependency for development of your module.

Ask yourself: will the installed package be required for use of my module, or will it only be required for developing it?

It might be useful.

Just type this into your command prompt while cd your/package/src/

go get github.com/go-gl/[email protected]

You get specific revision of package in question right into your source code, ready to use in import statement.

I was hunting around for an answer to this question. I found this helpful. The pattern wasn't apparent in the documentation for with_items.

https://github.com/ansible/ansible/issues/39389

- hosts: localhost
  connection: local
  gather_facts: no

  tasks:
    - name: set_fact
      set_fact:
        foo: "{{ foo }} + [ '{{ item }}' ]"
      with_items:
        - "one"
        - "two"
        - "three"
      vars:
        foo: []

    - name: Print the var
      debug:
        var: foo

Unfortunately, there doesn't appear to be a magic bullet. Bottom line up front: "context".

Google indeed ignores most punctuation, with the following exceptions:

1. Punctuation in popular terms that have particular meanings, like [ C++ ] or [ C# ] (both are names of programming languages), are not ignored.
2. The dollar sign ($) is used to indicate prices. [ nikon 400 ] and [ nikon $400 ] will give different results.
3. The hyphen - is sometimes used as a signal that the two words around it are very strongly connected. (Unless there is no space after the - and a space before it, in which case it is a negative sign.)
4. The underscore symbol _ is not ignored when it connects two words, e.g. [ quick_sort ].

As such, it is not well suited for these types of searchs. Google Code however does have syntax for searching through their code projects, that includes a robust language/syntax for dealing with "special characters". If looking at someone else's code could help solve a problem, this may be an option.

Unfortunately, this is not a limitation unique to google. You may find that your best successes hinge on providing as much 'context' to the problem as possible. If you are searching to find what $- means, providing information about the problem's domain may yield good results.

For example, searching "special perl variables" quickly yields your answer in the first entry on the results page.

I'm assuming you mean that you don't care which row is used to obtain the title, id, and commentname values (you have "rob" for all of the rows, but I don't know if that is actually something that would be enforced or not in your data model). If so, then you can use windowing functions to return the first row for a given email address:

select
    id,
    title,
    email,
    commentname

from
(
select 
    *, 
    row_number() over (partition by email order by id) as RowNbr 

from YourTable
) source

where RowNbr = 1

What about

lstCountry.Items[lstCountry.SelectedIndex].Text;

The SKU example used in the documentation was to provide the allowed characters in a new user-specified SKU.

For PhantomJS version above 1.5, consider this (verbatim copy of the build instructions on the phantom website):

For Ubuntu Linux (tested on a barebone install of Ubuntu 10.04 Lucid Lynx and Ubuntu 11.04 Natty Narwhal):

sudo apt-get install build-essential chrpath git-core libssl-dev libfontconfig1-dev
git clone git://github.com/ariya/phantomjs.git
cd phantomjs
git checkout 1.7
./build.sh

In My case it was something else. I had installed a package and then uninstall it and reinstall an earlier version. That left a residual configuration/runtime/asssemblyBinding/dependencyIdentity redirecting in my app.config. I had to correct it. I figured it out by looking at the Output window and selecting "Tests" in the drop down. The error message was there. This was a pain... I hope it helps someone else.

Use:

$(#id/.class).show()
$(#id/.class).hide()

This one is the best way.

Yet another custom implementation that doesn't require support table:

drop function if exists base64_encode;
create function base64_encode(_data blob)

Gist

You should convert charset after decoding: convert(base64_decode(base64_encode('????')) using utf8)

I think the choice between SortedSets/Lists and 'normal' sortable collections depends, whether you need sorting only for presentation purposes or at almost every point during runtime. Using a sorted collection may be much more expensive because the sorting is done everytime you insert an element.

If you can't opt for a collection in the JDK, you can take a look at the Apache Commons Collections

If you open your module settings (F4) you can nominate which paths contain 'source'. Intellij will then mark these directories in blue and allow you to add classes etc.

In a similar fashion you can highlight test directories for unit tests.

Look in your JBoss bin folder for the file run.bat (run.sh on Unix)

look for the line set JAVA_OPTS, (or just JAVA_OPTS on Unix) at the end of that line add -Xmx512m. Change the number to the amount of memory you want to allocate to JBoss.

If you are using a custom script to start your jboss instance, you can add the set JAVA_OPTS option there as well.

With > 4.0 of select2 I am using

$("select").select2({

These others did not work:

• dropdownCssClass: 'bigdrop'
• width: '100%'
• width: 'resolve'

Try this. This method will determine if (two) date spans are overlapping, regardless of the ordering of the method's input arguments. This can also be used with more than two date spans, by individually checking each date span combination (ex. with 3 date spans, run span1 against span2, span2 against span3, and span1 against span3):

    Console.WriteLine("COMPLETE");
    System.Console.ReadKey();
}

This is a stupid/hacky way

print count,    
print conv

The tool to do that would be

svnadmin dump

But for this to work, you need filesystem-access to the repository. And once you have that (and provided the repository is in FSFS format), you can just copy the repository to its new location (if it's in BDB format, dump/load is strongly recommended).

If you do not have filesystem access, you would have to ask your repository provider to provide the dump for you (and make them delete their repository - and hope they comply)

def gcdRecur(a, b):
    '''
    a, b: positive integers

    returns: a positive integer, the greatest common divisor of a & b.
    '''
    # Base case is when b = 0
    if b == 0:
        return a

    # Recursive case
    return gcdRecur(b, a % b)

This C# code is to fetch all items from a dynamodb table using BatchGet or CreateBatchGet

        string tablename = "AnyTableName"; //table whose data you want to fetch

        var BatchRead = ABCContext.Context.CreateBatchGet<ABCTable>(  

            new DynamoDBOperationConfig
            {
                OverrideTableName = tablename; 
            });

        foreach(string Id in IdList) // in case you are taking string from input
        {
            Guid objGuid = Guid.Parse(Id); //parsing string to guid
            BatchRead.AddKey(objGuid);
        }

        await BatchRead.ExecuteAsync();
        var result = BatchRead.Results;

// ABCTable is the table modal which is used to create in dynamodb & data you want to fetch

For personal teams

grep DEVELOPMENT_TEAM MyProject.xcodeproj/project.pbxproj

should give you the team ID

DEVELOPMENT_TEAM = ZU88ND8437;

So many coments, but i was helped this method:

sudo mysqladmin -u root password 'my password'

In my case after instalation i had get mysql service without a password for root user, and i was need set the password for my security.

As per the current latest Facebook API version 3.2, For users you can use this generic method for getting profile picture is https://graph.facebook.com/v3.2/{user-id}/picture?type=square you can visit documentation for user picture here. The possible values for type parameter in URL can be small, normal, album, large, square

For Groups and Pages, the profile picture is not available directly. You have to get them using access token. For Groups you have to use User Access Token and for Pages you can use both User Access Token and Page Access Token.

You can get Group's or Page's Profile Picture using the generic URL: https://graph.facebook.com/v3.2/{user-id}/picture?access_token={access-token}&type=square

I hope this is helpful for people who are looking for Page or Group Profile picture.

You want to convert it to an object first and then access normally making sure to cast it.

JObject obj = JObject.Parse(json);
string name = (string) obj["Name"];

String.split(String regex) is convenient but if you don't need the regular expression handling then go with the substring(..) example, java.util.StringTokenizer or use Apache commons lang 1. The performance difference when not using regular expressions can be a gain of 1 to 2 orders of magnitude in speed.

A cronjob could monitor this log and based on events created by your trigger it could invoke a php script. That is if you absolutely have no control over you insertion.. If you have transaction logs in you MySQL, you can create a trigger for purpose of a log instance creation.

Git 101:

git is a decentralized version control system. You do not necessary need a server to get up and running with git. Still you might want to do that as it looks cool, right? (It's also useful if you want to work on a single project from multiple computers.)

So to get a "server" running you need to run git init --bare <your_project>.git as this will create an empty repository, which you can then import on your machines without having to muck around in config files in your .git dir.

After this you could clone the repo on your clients as it is supposed to work, but I found that some clients (namely git-gui) will fail to clone a repo that is completely empty. To work around this you need to run cd <your_project>.git && touch <some_random_file> && git add <some_random_file> && git commit && git push origin master. (Note that you might need to configure your username and email for that machine's git if you hadn't done so in the past. The actual commands to run will be in the error message you get so I'll just omit them.)

So at this point you can clone the repository to any machine simply by running git clone <user>@<server>:<relative_path><your_project>.git. (As others have pointed out you might need to prefix it with ssh:// if you use the absolute path.) This assumes that you can already log in from your client to the server. (You'll also get bonus points for setting up a config file and keys for ssh, if you intend to push a lot of stuff to the remote server.)

Some relevant links:
This pretty much tells you what you need to know.
And this is for those who know the basic workings of git but sometimes forget the exact syntax.

In windows

$exec = 'ipconfig | findstr /R /C:"IPv4.*"';
exec($exec, $output);
preg_match('/\d+\.\d+\.\d+\.\d+/', $output[0], $matches);
print_r($matches[0]);

For me what happened was that I generated the app with rails new rails new chapter_2 but the RVM --default had rails 4.0.2 gem, but my chapter_2 project use a new gemset with rails 3.2.16.

So when I ran

rails generate scaffold User name:string email:string

the console showed

Usage:
   rails new APP_PATH [options]

So I fixed the RVM and the gemset with the rails 3.2.16 gem , and then generated the app again then I executed

 rails generate scaffold User name:string email:string

and it worked

coonstructors are called automatically when you create a new object, thereby "constructing" the object. The reason you can have more than one init is because names are just references in python, and you are allowed to change what each variable references whenever you want (hence dynamic typing)

def func(): #now func refers to an empty funcion
    pass
...
func=5      #now func refers to the number 5
def func():
    print "something"    #now func refers to a different function

in your class definition, it just keeps the later one

custom validation step by step

   <div *ngIf="demo.control.hasError('required')"> field  is required.</div>
   <div *ngIf="demo.control.hasError('invalidChar')">Special Characters are not Allowed</div>
 </div>
  </form>

Component App.ts

import {Control, ControlGroup, FormBuilder, Validators, NgForm, NgClass} from 'angular2/common';
import {CustomValidator} from '../../yourServices/validatorService';

under class define

 demoForm: ControlGroup;
constructor( @Inject(FormBuilder) private Fb: FormBuilder ) {
    this.demoForm = Fb.group({
       spec: new Control('', Validators.compose([Validators.required,   CustomValidator.specialCharValidator])),
      })
}

under {../../yourServices/validatorService.ts}

       }
       else {            
           return { 'invalidChar': true };
       }
   }

 }

 }

you can use this for url with parameters:

lynx -dump "http://vps-managed.com/tasks.php?code=23456"

lynx is available on all systems by default.

If you want to split/cut the array on an index i,

arr = arr.drop(i)

> arr = [1,2,3,4,5]
 => [1, 2, 3, 4, 5] 
> arr.drop(2)
 => [3, 4, 5] 

In the menu, go to RUN > services.msc and hit enter to get the services window and check for the IIS ADMIN service. If it is not present, then reinstall IIS using your windows CD.

1. You can backup and restore the database using Management Studio.
2. Again from Management Studio you can use "copy database".
3. you can even do it manually if there is a reason to do so. I mean manually create the target db and manually copying data by sql statements...

can you clarify why you ask this? Is it that you dont have expierience in doing it or something else?

Including this in the read.csv command worked for me: strip.white = TRUE

(I found this solution here.)

UTF-8 string length

In addition to fedorqui's correct answer, I would like to show the difference between string length and byte length:

myvar='Généralités'
chrlen=${#myvar}
oLang=$LANG oLcAll=$LC_ALL
LANG=C LC_ALL=C
bytlen=${#myvar}
LANG=$oLang LC_ALL=$oLcAll
printf "%s is %d char len, but %d bytes len.\n" "${myvar}" $chrlen $bytlen

will render:

Généralités is 11 char len, but 14 bytes len.

you could even have a look at stored chars:

myvar='Généralités'
chrlen=${#myvar}
oLang=$LANG oLcAll=$LC_ALL
LANG=C LC_ALL=C
bytlen=${#myvar}
printf -v myreal "%q" "$myvar"
LANG=$oLang LC_ALL=$oLcAll
printf "%s has %d chars, %d bytes: (%s).\n" "${myvar}" $chrlen $bytlen "$myreal"

will answer:

Généralités has 11 chars, 14 bytes: ($'G\303\251n\303\251ralit\303\251s').

Nota: According to Isabell Cowan's comment, I've added setting to $LC_ALL along with $LANG.

Length of an argument

Argument work same as regular variables

strLen() {
    local bytlen sreal oLang=$LANG oLcAll=$LC_ALL
    LANG=C LC_ALL=C
    bytlen=${#1}
    printf -v sreal %q "$1"
    LANG=$oLang LC_ALL=$oLcAll
    printf "String '%s' is %d bytes, but %d chars len: %s.\n" "$1" $bytlen ${#1} "$sreal"
}

will work as

strLen théorème
String 'théorème' is 10 bytes, but 8 chars len: $'th\303\251or\303\250me'

Useful printf correction tool:

If you:

for string in Généralités Language Théorème Février  "Left: ?" "Yin Yang ?";do
    printf " - %-14s is %2d char length\n" "'$string'"  ${#string}
done

 - 'Généralités' is 11 char length
 - 'Language'     is  8 char length
 - 'Théorème'   is  8 char length
 - 'Février'     is  7 char length
 - 'Left: ?'    is  7 char length
 - 'Yin Yang ?' is 10 char length

Not really pretty... For this, there is a little function:

strU8DiffLen () { 
    local bytlen oLang=$LANG oLcAll=$LC_ALL
    LANG=C LC_ALL=C
    bytlen=${#1}
    LANG=$oLang LC_ALL=$oLcAll
    return $(( bytlen - ${#1} ))
}

Then now:

for string in Généralités Language Théorème Février  "Left: ?" "Yin Yang ?";do
    strU8DiffLen "$string"
    printf " - %-$((14+$?))s is %2d chars length, but uses %2d bytes\n" \
        "'$string'" ${#string} $((${#string}+$?))
  done 

 - 'Généralités'  is 11 chars length, but uses 14 bytes
 - 'Language'     is  8 chars length, but uses  8 bytes
 - 'Théorème'     is  8 chars length, but uses 10 bytes
 - 'Février'      is  7 chars length, but uses  8 bytes
 - 'Left: ?'      is  7 chars length, but uses  9 bytes
 - 'Yin Yang ?'   is 10 chars length, but uses 12 bytes

Unfortunely, this is not perfect!

But there left some strange UTF-8 behaviour, like double-spaced chars, zero spaced chars, reverse deplacement and other that could not be as simple...

Have a look at diffU8test.sh or diffU8test.sh.txt for more limitations.

You probably need to break up your if statement into smaller pieces. That being said, you can do two things:

• wrap the statement into do {} while (false) and use real break (not recommended!!! huge kludge!!!)

• put the statement into its own subroutine and use return This may be the first step to improving your code.

On Mac you can navigate to the location in Project view where you want to create your class and then use ?N followed by Enter.

After a lot of googling and trying all above...the only thing that solved my problem was this command:

When the normType is NORM_MINMAX, cv::normalize normalizes _src in such a way that the min value of dst is alpha and max value of dst is beta. cv::normalize does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).

CV_8UC1 says how many channels dst has.

The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize

If you have

dict = {key1:value1, key2:value2, key3:value3,...}

In Python 2, dict.items() copies each tuples and returns the list of tuples in dictionary i.e. [(key1,value1), (key2,value2), ...]. Implications are that the whole dictionary is copied to new list containing tuples

dict = {i: i * 2 for i in xrange(10000000)}  
# Slow and memory hungry.
for key, value in dict.items():
    print(key,":",value)

dict.iteritems() returns the dictionary item iterator. The value of the item returned is also the same i.e. (key1,value1), (key2,value2), ..., but this is not a list. This is only dictionary item iterator object. That means less memory usage (50% less).

• Lists as mutable snapshots: d.items() -> list(d.items())
• Iterator objects: d.iteritems() -> iter(d.items())

The tuples are the same. You compared tuples in each so you get same.

dict = {i: i * 2 for i in xrange(10000000)}  
# More memory efficient.
for key, value in dict.iteritems():
    print(key,":",value)

In Python 3, dict.items() returns iterator object. dict.iteritems() is removed so there is no more issue.

To print the second line:

awk 'FNR == 2 {print}'

To print the second field:

awk '{print $2}'

To print the third field of the fifth line:

awk 'FNR == 5 {print $3}'

Here's an example with a header line and (redundant) field descriptions:

awk 'BEGIN {print "Name\t\tAge"}  FNR == 5 {print "Name: "$3"\tAge: "$2}'

There are better ways to align columns than "\t\t" by the way.

Use exit to stop as soon as you've printed the desired record if there's no reason to process the whole file:

awk 'FNR == 2 {print; exit}'

Given that you have an instance of ResourceBundle and you can get String by:

String val = bundle.getString(key); 

I solved my Japanese display problem by:

return new String(val.getBytes("ISO-8859-1"), "UTF-8");

There is a way to SELECT NOTHING that solve your problem.

1. Create a shape (one rectangle)
2. Name it in Shapes Database >>> for example: "Ready"
3. Refer to it MYDOC.Shapes("Ready") and change the visibility to False

When you want that Excel SELECT NOTHING do it:

MYDOC.Shapes("Ready").visible=True
MYDOC.Shapes("Ready").Select
MYDOC.Shapes("Ready").visible=False

This HIDE the selection and nothing still selected in your window PLUS: The word "Ready" is shown at the Left Top in your Sheet.

There is no search and replace function or stream editing at the command line in XP or 2k3 (dont know about vista or beyond). So, you'll need to use a script like the one Ghostdog posted, or a search and replace capable tool like sed.

There is more than one way to do it, as this script shows:

@echo off
    SETLOCAL=ENABLEDELAYEDEXPANSION

    rename text.file text.tmp
    for /f %%a in (text.tmp) do (
        set foo=%%a
        if !foo!==ex3 set foo=ex5
        echo !foo! >> text.file) 
del text.tmp

Your great great great great great great great grandfather should upgrade to SQL Server 2008 and use the DateTime2 data type, which supports dates in the range: 0001-01-01 through 9999-12-31.

Best solution for cropping an UIImage in Swift, in term of precision, pixels scaling ...:

private func squareCropImageToSideLength(let sourceImage: UIImage,
    let sideLength: CGFloat) -> UIImage {
        // input size comes from image
        let inputSize: CGSize = sourceImage.size

        // round up side length to avoid fractional output size
        let sideLength: CGFloat = ceil(sideLength)

        // output size has sideLength for both dimensions
        let outputSize: CGSize = CGSizeMake(sideLength, sideLength)

        // calculate scale so that smaller dimension fits sideLength
        let scale: CGFloat = max(sideLength / inputSize.width,
            sideLength / inputSize.height)

        // scaling the image with this scale results in this output size
        let scaledInputSize: CGSize = CGSizeMake(inputSize.width * scale,
            inputSize.height * scale)

        // determine point in center of "canvas"
        let center: CGPoint = CGPointMake(outputSize.width/2.0,
            outputSize.height/2.0)

        // calculate drawing rect relative to output Size
        let outputRect: CGRect = CGRectMake(center.x - scaledInputSize.width/2.0,
            center.y - scaledInputSize.height/2.0,
            scaledInputSize.width,
            scaledInputSize.height)

        // begin a new bitmap context, scale 0 takes display scale
        UIGraphicsBeginImageContextWithOptions(outputSize, true, 0)

        // optional: set the interpolation quality.
        // For this you need to grab the underlying CGContext
        let ctx: CGContextRef = UIGraphicsGetCurrentContext()
        CGContextSetInterpolationQuality(ctx, kCGInterpolationHigh)

        // draw the source image into the calculated rect
        sourceImage.drawInRect(outputRect)

        // create new image from bitmap context
        let outImage: UIImage = UIGraphicsGetImageFromCurrentImageContext()

        // clean up
        UIGraphicsEndImageContext()

        // pass back new image
        return outImage
}

Instructions used to call this function:

let image: UIImage = UIImage(named: "Image.jpg")!
let squareImage: UIImage = self.squareCropImageToSideLength(image, sideLength: 320)
self.myUIImageView.image = squareImage

Note: the initial source code inspiration written in Objective-C has been found on "Cocoanetics" blog.

I feel like all the answers showing use of a CTE or Sub Query are sufficient fixes for this, but I don't see anyone getting to the heart of why OP has a problem. The reason why what OP suggested doesn't work is due to logical query processing order here:

1. FROM
2. ON
3. JOIN
4. WHERE
5. GROUP BY
6. WITH CUBE/ROLLUP
7. HAVING
8. SELECT
9. DISTINCT
10. ORDER BY
11. TOP
12. OFFSET/FETCH

I believe this contributes to the answer greatly, because it explains why issues like this one occur. WHERE is always processed before SELECT making a CTE or Sub Query necessary for many functions. You will see this a lot in SQL Server.

You can use this function wherever you need to call it:

function scroll_to(div){
   if (div.scrollTop < div.scrollHeight - div.clientHeight)
        div.scrollTop += 10; // move down

}

jquery.com: ScrollTo

        //Date/time pattern of desired output date (24 Hours format HH - Used for 24 hours)
        DateFormat outputformat = new SimpleDateFormat("HH:mm:ss");
        Date date = null;
        String output = null;

        //Returns Date object
        date = df.parse(twelveHoursTime);

        //old date format to new date format
        output = outputformat.format(date);
        System.out.println(output);

        return output;
    }

One notable reason to avoid overusing the heap is for performance -- specifically involving the performance of the default memory management mechanism used by C++. While allocation can be quite quick in the trivial case, doing a lot of new and delete on objects of non-uniform size without strict order leads not only to memory fragmentation, but it also complicates the allocation algorithm and can absolutely destroy performance in certain cases.

That's the problem that memory pools where created to solve, allowing to to mitigate the inherent disadvantages of traditional heap implementations, while still allowing you to use the heap as necessary.

Better still, though, to avoid the problem altogether. If you can put it on the stack, then do so.

May be this can help:

Use MyTest
Go
select * from information_schema.COLUMNS where TABLE_NAME='employee'

{ where: MyTest= DatabaseName Employee= TableName } --Optional conditions

Try:

EditText edt = (EditText) findViewById(R.id.YourEditText);
RelativeLayout.LayoutParams lp =
    new RelativeLayout.LayoutParams
    (
        LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT
    );
lp.setMargins(25, 0, 0, 0); // move 25 px to right (increase left margin)
edt.setLayoutParams(lp); // lp.setMargins(left, top, right, bottom);

Newer versions: (from 8.4 - mentioned in release notes)

TABLE mytablename;

Longer but works on all versions:

SELECT * FROM mytablename;

You may wish to use \x first if it's a wide table, for readability.

For long data:

SELECT * FROM mytable LIMIT 10;

or similar.

For wide data (big rows), in the psql command line client, it's useful to use \x to show the rows in key/value form instead of tabulated, e.g.

 \x
SELECT * FROM mytable LIMIT 10;

Note that in all cases the semicolon at the end is important.

An other solution rm(list=ls(pattern="temp")), remove all objects matching the pattern.

Use this, Tested and 100% Worked!

For VB.NET

Dim myString As String
Dim oldValue As String
Dim newValue As String

myString = Form1.TextBox1.Text
oldValue = TextBox1.Text
newValue = TextBox2.Text

Dim working As String = myString
Dim index As Integer = working.IndexOf(oldValue, StringComparison.CurrentCultureIgnoreCase)

While index <> -1
    working = working.Remove(index, oldValue.Length)
    working = working.Insert(index, newValue)
    index = index + newValue.Length
    index = working.IndexOf(oldValue, index, StringComparison.CurrentCultureIgnoreCase)
    Form1.TextBox1.Text = working
End While

For C#

private void Button2_Click(System.Object sender, System.EventArgs e)
{
    string myString;
    string oldValue;
    string newValue;

    myString = Form1.TextBox1.Text;
    oldValue = TextBox1.Text;
    newValue = TextBox2.Text;

    string working = myString;
    int index = working.IndexOf(oldValue, StringComparison.CurrentCultureIgnoreCase);

    while (index != -1)
    {
        working = working.Remove(index, oldValue.Length);
        working = working.Insert(index, newValue);
        index = index + newValue.Length;
        index = working.IndexOf(oldValue, index, StringComparison.CurrentCultureIgnoreCase);
        Form1.TextBox1.Text = working;
    }
}

My solution is add a utility method to your utilities class (hint hint) to parse the system version and manually compensate for float number ordering.

Also, this code is rather simple, so I hope it helps some newbies. Simply pass in a target float, and get back a BOOL.

Declare it in your shared class like this:

(+) (BOOL) iOSMeetsOrExceedsVersion:(float)targetVersion;

Call it like this:

BOOL shouldBranch = [SharedClass iOSMeetsOrExceedsVersion:5.0101];

(+) (BOOL) iOSMeetsOrExceedsVersion:(float)targetVersion {

/*
 Note: the incoming targetVersion should use 2 digits for each subVersion --

 example 5.01 for v5.1, 5.11 for v5.11 (aka subversions above 9), 5.0101 for v5.1.1, etc.
*/

// Logic: as a string, system version may have more than 2 segments (example: 5.1.1)
// so, a direct conversion to a float may return an invalid number
// instead, parse each part directly

NSArray *sysVersion = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:@"."];
float floatVersion = [[sysVersion objectAtIndex:0] floatValue];
if (sysVersion.count > 1) {
    NSString* subVersion = [sysVersion objectAtIndex:1];
    if (subVersion.length == 1)
        floatVersion += ([[sysVersion objectAtIndex:1] floatValue] *0.01);
    else
        floatVersion += ([[sysVersion objectAtIndex:1] floatValue] *0.10);
}
if (sysVersion.count > 2) {
    NSString* subVersion = [sysVersion objectAtIndex:2];
    if (subVersion.length == 1)
        floatVersion += ([[sysVersion objectAtIndex:2] floatValue] *0.0001);
    else
        floatVersion += ([[sysVersion objectAtIndex:2] floatValue] *0.0010);
}

if (floatVersion  >= targetVersion) 
    return TRUE;

// else
return FALSE;
 }

I got an example here that struck me!

foo.py

import bar

class gX(object):
    g = 10

bar.py

from foo import gX

o = gX()

main.py

import foo
import bar

print "all done"

At the command line: $ python main.py

You need run visudo and in the editor that it opens write:

igor    ALL=(ALL) ALL

That line grants all permissions to user igor.

If you want permit to run only some commands, you need to list them in the line:

igor    ALL=(ALL) /bin/kill, /bin/ps

1024 is appropriate for a wide variety of circumstances, although in practice you may see better performance with a larger or smaller buffer size.

This would depend on a number of factors including file system block size and CPU hardware.

It is also common to choose a power of 2 for the buffer size, since most underlying hardware is structured with fle block and cache sizes that are a power of 2. The Buffered classes allow you to specify the buffer size in the constructor. If none is provided, they use a default value, which is a power of 2 in most JVMs.

Regardless of which buffer size you choose, the biggest performance increase you will see is moving from nonbuffered to buffered file access. Adjusting the buffer size may improve performance slightly, but unless you are using an extremely small or extremely large buffer size, it is unlikely to have a signifcant impact.

Both are models of an object that you have some means of controlling inputs and observing outputs. With an emulator, you want the output to be exactly what the object you are emulating would produce. With a simulator, you want certain properties of your output to be similar to what the object would produce.

Let me give an example -- suppose you want to do some system testing to see how adding a new sensor (like a thermometer) to a system would affect the system. You know that the thermometer sends a message 8 time a second containing its measurement.

Simulation -- if you do not have the thermometer yet, but you want to test that this message rate will not overload you system, you can simulate the sensor by attaching a unit that sends a random number 8 times a second. You can run any test that does not rely on the actual value the sensor sends.

Emulation -- suppose you have a very expensive thermometer that measures to 0.001 C, and you want to see if you can get by with a cheaper thermometer that only measures to the nearest 0.5 C. You can emulate the cheaper thermometer using an expensive thermometer by rounding the reading to the nearest 0.5 C and running tests that rely on the temperature values.

// Executes: SELECT * FROM mytable LIMIT 10 OFFSET 20
// get([$table = ''[, $limit = NULL[, $offset = NULL]]])
$query = $this->db->get('mytable', 10, 20);

// get_where sample, 
$query = $this->db->get_where('mytable', array('id' => $id), 10, 20);

// Produces: LIMIT 10
$this->db->limit(10);

If you don't want to make the button a separate image, you can use the <area> tag. This is done by using html similar to this:

<img src="imgsrc" width="imgwidth" height="imgheight" alt="alttext" usemap="#mapname">

<map name="mapname">
    <area shape="rect" coords="see note 1" href="link" alt="alttext">
</map>

Note 1: The coords=" " attribute must be formatted in this way: coords="x1,y1,x2,y2" where:

x1=top left X coordinate
y1=top left Y coordinate
x2=bottom right X coordinate
y2=bottom right Y coordinate

Note 2: The usemap="#mapname" attribute must include the #.

EDIT:

I looked at your code and added in the <map> and <area> tags where they should be. I also commented out some parts that were either overlapping the image or seemed there for no use.

Notes:

1. The coord="48,341,294,275" is in reference to your screenshot you posted.
2. The src="./test.png" is the location and name of the screenshot you posted on my computer.

I know that this may not be a popular answer but I do agree with @Randy Minder on using third party tool when more complex comparison is needed.

This specific case here is easy and for this case such tools are not needed but this can get complex easily if you introduce more columns, databases on two servers, more complex comparison criteria and such.

There are a lot of these tools such as ApexSQL Data Diff or Quest Toad and you can always use them in trial mode to get the job done.

No, there is no simpler way. You only can lose the type=array.

<numbers>
    <value>3</value>
    <value>2</value>
    <value>1</value>
</numbers>

I had the same problem, but managed to fix it by suppressing the 'Expect: 100-continue' header that cURL usually sends (the following is PHP code, but should work similarly with other cURL APIs):

curl_setopt($curl, CURLOPT_HTTPHEADER, array('Expect:'));

By the way, I am sending calls to the HTTP server that is included in the JDK 6 REST stuff, which has all kinds of problems. In this case, it first sends a 100 response, and then with some requests doesn't send the subsequent 200 response correctly.

Use this site: https://rawgit.com , it works for me as I don't have permission issue with the svg file.
Please pay attention that RawGit is not a service of github, as mentioned in Rawgit FAQ :

RawGit is not associated with GitHub in any way. Please don't contact GitHub asking for help with RawGit

Enter the url of svg you need, such as :

https://github.com/sel-fish/redis-experiments/blob/master/dat/memDistrib-jemalloc-4.0.3.svg

Then, you can get the url bellow which can be used to display:

https://cdn.rawgit.com/sel-fish/redis-experiments/master/dat/memDistrib-jemalloc-4.0.3.svg

If the above solution does not work for you, try this:

#1.1 Do NOT ignore file pattern in  any subdirectory
!*/config.php
#1.2 ...only ignore it in the current directory
/config.php

##########################

# 2.1 Ignore file pattern everywhere
config.php
# 2.2 ...but NOT in the current directory
!/config.php

This is what I used when I stumbled upon this problem.

def order(list_item, i): # reorder at index i
    order_at = list_item.index(i)
    ordered_list = list_item[order_at:] + list_item[:order_at]
    return ordered_list

EX: for the the lowercase letters

order(string.ascii_lowercase, 'h'):
>>> 'hijklmnopqrstuvwxyzabcdefg'

It simply just shifts the list to a specified index

The backdrop to my solution recommendation is the story of a friend who, well into the second week of his first job, wiped half a build-server clean. So the basic task is to figure out if a file exists, and if so, let's delete it. But there are a few treacherous rapids on this river:

• Everything is a file.

• Scripts have real power only if they solve general tasks

• To be general, we use variables

• We often use -f force in scripts to avoid manual intervention

• And also love -r recursive to make sure we create, copy and destroy in a timely fashion.

Consider the following scenario:

We have the file we want to delete: filesexists.json

This filename is stored in a variable

<host>:~/Documents/thisfolderexists filevariable="filesexists.json"

We also hava a path variable to make things really flexible

<host>:~/Documents/thisfolderexists pathtofile=".."

<host>:~/Documents/thisfolderexists ls $pathtofile

filesexists.json  history20170728  SE-Data-API.pem  thisfolderexists

So let's see if -e does what it is supposed to. Does the files exist?

<host>:~/Documents/thisfolderexists [ -e $pathtofile/$filevariable ]; echo $?

0

It does. Magic.

However, what would happen, if the file variable got accidentally be evaluated to nuffin'

<host>:~/Documents/thisfolderexists filevariable=""

<host>:~/Documents/thisfolderexists [ -e $pathtofile/$filevariable ]; echo $?

0

What? It is supposed to return with an error... And this is the beginning of the story how that entire folder got deleted by accident

An alternative could be to test specifically for what we understand to be a 'file'

<host>:~/Documents/thisfolderexists filevariable="filesexists.json"

<host>:~/Documents/thisfolderexists test -f $pathtofile/$filevariable; echo $?

0

So the file exists...

<host>:~/Documents/thisfolderexists filevariable=""

<host>:~/Documents/thisfolderexists test -f $pathtofile/$filevariable; echo $?

1

So this is not a file and maybe, we do not want to delete that entire directory

man test has the following to say:

-b FILE

       FILE exists and is block special

-c FILE

       FILE exists and is character special

-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)

You can use:

npm show {pkg} version

(so npm show express version will return now 3.0.0rc3).

Here is a solution for reading - not writing - the extended properties based on what I found on this page and at help with shell32 objects.

To be clear this is a hack. It looks like this code will still run on Windows 10 but will hit on some empty properties. Previous version of Windows should use:

        var i = 0;
        while (true)
        {
            ...
            if (String.IsNullOrEmpty(header)) break;
            ...
            i++;

On Windows 10 we assume that there are about 320 properties to read and simply skip the empty entries:

    private Dictionary<string, string> GetExtendedProperties(string filePath)
    {
        var directory = Path.GetDirectoryName(filePath);
        var shell = new Shell32.Shell();
        var shellFolder = shell.NameSpace(directory);
        var fileName = Path.GetFileName(filePath);
        var folderitem = shellFolder.ParseName(fileName);
        var dictionary = new Dictionary<string, string>();
        var i = -1;
        while (++i < 320)
        {
            var header = shellFolder.GetDetailsOf(null, i);
            if (String.IsNullOrEmpty(header)) continue;
            var value = shellFolder.GetDetailsOf(folderitem, i);
            if (!dictionary.ContainsKey(header)) dictionary.Add(header, value);
            Console.WriteLine(header +": " + value);
        }
        Marshal.ReleaseComObject(shell);
        Marshal.ReleaseComObject(shellFolder);
        return dictionary;
    }

As mentioned you need to reference the Com assembly Interop.Shell32.

If you get an STA related exception, you will find the solution here:

Exception when using Shell32 to get File extended properties

I have no idea what those properties names would be like on a foreign system and couldn't find information about which localizable constants to use in order to access the dictionary. I also found that not all the properties from the Properties dialog were present in the dictionary returned.

BTW this is terribly slow and - at least on Windows 10 - parsing dates in the string retrieved would be a challenge so using this seems to be a bad idea to start with.

On Windows 10 you should definitely use the Windows.Storage library which contains the SystemPhotoProperties, SystemMusicProperties etc. https://docs.microsoft.com/en-us/windows/uwp/files/quickstart-getting-file-properties

And finally, I posted a much better solution that uses WindowsAPICodePack there

Try using javascript:void(0) as follows-

<a href="javascript:void(0)" onclick="...">Text</a>

If you explicitly cast double to int, the decimal part will be truncated. For example:

int x = (int) 4.97542;   //gives 4 only
int x = (int) 4.23544;   //gives 4 only

Moreover, you may also use Math.floor() method to round values in case you want double value in return.

According to the GCC manual for omp_get_num_threads:

In a sequential section of the program omp_get_num_threads returns 1

So this:

cout<<"sum="<<sum<<endl;
cout<<"threads="<<omp_get_num_threads()<<endl;

Should be changed to something like:

#pragma omp parallel
{
    cout<<"sum="<<sum<<endl;
    cout<<"threads="<<omp_get_num_threads()<<endl;
}

The code I use follows Hristo's advice of disabling dynamic teams, too.

intel mkl suggests in-place and out-of-place transposition/copying matrices. here is the link to the documentation. I would recommend trying out of place implementation as faster ten in-place and into the documentation of the latest version of mkl contains some mistakes.

def solve(s):
    for i in s[:].split():
        s = s.replace(i, i.capitalize())

This is the actual code for work. .title() will not work at '12name' case

Update for ECMAScript 2017:

Math.clamp(x, lower, upper)

But note that as of today, it's a Stage 1 proposal. Until it gets widely supported, you can use a polyfill.

You can use JHAT, The Java Heap Analysis Tool provided by default with the JDK. It's command line but starts a web server/browser you use to examine the memory. Not the most user friendly, but at least it's already installed most places you'll go. A very useful view is the "heap histogram" link at the very bottom.

ex: jhat -port 7401 -J-Xmx4G dump.hprof

jhat can execute OQL "these days" as well (bottom link "execute OQL")

use ILIKE

SELECT * FROM trees WHERE trees.`title` ILIKE '%elm%';

it worked for me !!

"Access violation reading location 0x00000000" means that you're derefrencing a pointer that hasn't been initialized and therefore has garbage values. Those garbage values could be anything, but usually it happens to be 0 and so you try to read from the memory address 0x0, which the operating system detects and prevents you from doing.

Check and make sure that the array invaders[] is what you think it should be.

Also, you don't seem to be updating i ever - meaning that you keep placing the same Invader object into location 0 of invaders[] at every loop iteration.

"An App Access Token does not expire unless you refresh the application secret through your app settings."

Ok here's how I fixed this

My model is a list of categories. Each category contains a list of its subcategories.
with this in mind, every time in the foreach loop, each RadioButton will have its category's ID (which is unique) as its name attribue.
And I also used Html.RadioButton instead of Html.RadioButtonFor.

Here's the final 'working' pseudo-code:

@foreach (var cat in Model.Categories)
{
  //A piece of code & html here
  @foreach (var item in cat.SubCategories)
  {
     @Html.RadioButton(item.CategoryID.ToString(), item.ID)
  }    
}

The result is:

<input name="127" type="radio" value="110">

Please note that I HAVE NOT put all these radio button groups inside a form. And I don't know if this solution will still work properly in a form.

Thanks to all of the people who helped me solve this ;)

You forgot the namespace you're referring to. Add

using namespace std;

to avoid std::string all the time.

Below code works for me

   public static void sftpsript(String filepath) {

 try {
  String user ="demouser"; // username for remote host
  String password ="demo123"; // password of the remote host

   String host = "demo.net"; // remote host address
  JSch jsch = new JSch();
  Session session = jsch.getSession(user, host);
  session.setPassword(password);
  session.connect();

  ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
  sftpChannel.connect();

  sftpChannel.put("I:/demo/myOutFile.txt", "/tmp/QA_Auto/myOutFile.zip");
  sftpChannel.disconnect();
  session.disconnect();
 }catch(Exception ex){
     ex.printStackTrace();
 }
   }

OR using StrictHostKeyChecking as "NO" (security consequences)

public static void sftpsript(String filepath) {

 try {
  String user ="demouser"; // username for remote host
  String password ="demo123"; // password of the remote host

   String host = "demo.net"; // remote host address
  JSch jsch = new JSch();
   Session session = jsch.getSession(user, host, 22);
   Properties config = new Properties();
   config.put("StrictHostKeyChecking", "no");
   session.setConfig(config);;
   session.setPassword(password);
   System.out.println("user=="+user+"\n host=="+host);
   session.connect();

  ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
  sftpChannel.connect();

  sftpChannel.put("I:/demo/myOutFile.txt", "/tmp/QA_Auto/myOutFile.zip");
  sftpChannel.disconnect();
  session.disconnect();
 }catch(Exception ex){
     ex.printStackTrace();
 }
   }

Use CardView for Round Rectangle. CardView give more functionality like cardCornerRadius, cardBackgroundColor, cardElevation & many more. CardView make UI more suitable then Custom Round Rectangle drawable.

mbaird's answer works fine. Just be aware that there seems to be a bug in Android (2.1 at least), that if you set any individual corner's radius to 0, it forces all the corners to 0 (at least that's the case with "dp" units; I didn't try it with any other units).

I needed a shape where the top corners were rounded and the bottom corners were square. I got achieved this by setting the corners I wanted to be square to a value slightly larger than 0: 0.1dp. This still renders as square corners, but it doesn't force the other corners to be 0 radius.

Earlier mentioned solution with PHP version check added:

    $max_includes = version_compare(PHP_VERSION, '5', '<') ? 0 : 1;
    if (count(get_included_files()) <= $max_includes)
    {
        exit('Direct access is not allowed.');
    }

Just double click on the table name and press Alt+F1

See this table.

A 101x101 QR code, with high level error correction, can hold 3248 bits, or 406 bytes. Probably not enough for any meaningful SVG/XML data.

A 177x177 grid, depending on desired level of error correction, can store between 1273 and 2953 bytes. Maybe enough to store something small.

I prefer to convert the map to a JSON string it is:

• a standard
• human readable
• supported in editors like Sublime, VS Code, with syntax highlighting, formatting and section hide/show
• supports JPath so editors can report exactly which part of the object you have navigated to

• supports nested complex types within the object

  import com.fasterxml.jackson.core.JsonProcessingException;
  import com.fasterxml.jackson.databind.ObjectMapper;
  
  public static String getAsFormattedJsonString(Object object)
  {
      ObjectMapper mapper = new ObjectMapper();
      try
      {
          return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(object);
      }
      catch (JsonProcessingException e)
      {
          e.printStackTrace();
      }
      return "";
  }
  

Swift 3

class MyObject: NSObject, NSCoding  {
    let name : String
    let url : String
    let desc : String

    init(tuple : (String,String,String)){
        self.name = tuple.0
        self.url = tuple.1
        self.desc = tuple.2
    }
    func getName() -> String {
        return name
    }
    func getURL() -> String{
        return url
    }
    func getDescription() -> String {
        return desc
    }
    func getTuple() -> (String, String, String) {
        return (self.name,self.url,self.desc)
    }

    required init(coder aDecoder: NSCoder) {
        self.name = aDecoder.decodeObject(forKey: "name") as? String ?? ""
        self.url = aDecoder.decodeObject(forKey: "url") as? String ?? ""
        self.desc = aDecoder.decodeObject(forKey: "desc") as? String ?? ""
    }

    func encode(with aCoder: NSCoder) {
        aCoder.encode(self.name, forKey: "name")
        aCoder.encode(self.url, forKey: "url")
        aCoder.encode(self.desc, forKey: "desc")
    }
    }

to store and retrieve:

func save() {
            let data  = NSKeyedArchiver.archivedData(withRootObject: object)
            UserDefaults.standard.set(data, forKey:"customData" )
        }
        func get() -> MyObject? {
            guard let data = UserDefaults.standard.object(forKey: "customData") as? Data else { return nil }
            return NSKeyedUnarchiver.unarchiveObject(with: data) as? MyObject
        }

I use this, if there is an absolute path (this is an example):

$img = imagecreatefromjpeg($_SERVER['DOCUMENT_ROOT']."/Folder-B/image1.jpg");

if there is a picture to show, this is enough:

echo("<img src='/Folder-B/image1.jpg'>");

var charCount = "string with periods...".Count(x => '.' == x);

A couple of tips:

• Try to set the path manually by checking 'advanced' and modifying CMAKE_LINKER and CMAKE_MAKE_PROGRAM
• Delete the cache - in the CMake with GUI go to: File ? Delete Cache.

My problem was a combination of previously stated: I have set the compiler version to 15 instead of 14 and when corrected, I had to delete the cache.

I also started the Visual Studio command prompt as an administrator and from there I ran the cmake-gui.exe

Then everything worked as it was supposed to.

Looks like this trick works in SQL Server and is shorter (based in previous answers)

SELECT 1.0*MyInt1/MyInt2

Or:

SELECT (1.0*MyInt1)/MyInt2

Whenever you have to perform some action on the click of the Spinner in Android, use the following method.

mspUserState.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            doWhatIsRequired();
        }
        return false;
    }
});

One thing to keep in mind is always to return False while using the above method. If you will return True then the dropdown items of the spinner will not be displayed on clicking the Spinner.

HTML provides no way to generate JSON from form data.

If you really want to handle it from the client, then you would have to resort to using JavaScript to:

1. gather your data from the form via DOM
2. organise it in an object or array
3. generate JSON with JSON.stringify
4. POST it with XMLHttpRequest

You'd probably be better off sticking to application/x-www-form-urlencoded data and processing that on the server instead of JSON. Your form doesn't have any complicated hierarchy that would benefit from a JSON data structure.

Update in response to major rewrite of the question…

• Your JS has no readystatechange handler, so you do nothing with the response
• You trigger the JS when the submit button is clicked without cancelling the default behaviour. The browser will submit the form (in the regular way) as soon as the JS function is complete.

In scikit version 0.22, you can do it like this

from sklearn.metrics import multilabel_confusion_matrix

y_true = ["cat", "ant", "cat", "cat", "ant", "bird"]
y_pred = ["ant", "ant", "cat", "cat", "ant", "cat"]

mcm = multilabel_confusion_matrix(y_true, y_pred,labels=["ant", "bird", "cat"])

tn = mcm[:, 0, 0]
tp = mcm[:, 1, 1]
fn = mcm[:, 1, 0]
fp = mcm[:, 0, 1]

You are printing the enum object. Use the .value attribute if you wanted just to print that:

print(D.x.value)

See the Programmatic access to enumeration members and their attributes section:

If you have an enum member and need its name or value:

>>>
>>> member = Color.red
>>> member.name
'red'
>>> member.value
1

You could add a __str__ method to your enum, if all you wanted was to provide a custom string representation:

class D(Enum):
    def __str__(self):
        return str(self.value)

    x = 1
    y = 2

Demo:

>>> from enum import Enum
>>> class D(Enum):
...     def __str__(self):
...         return str(self.value)
...     x = 1
...     y = 2
... 
>>> D.x
<D.x: 1>
>>> print(D.x)
1

I had the same question, but then I had a "duh" moment. Instead of writing

x ~ y

write

y ~ x

Obviously this matches "x" instead of "y", but it answers the "is there a match?" question, and simple DOM traversal may get you to the right element more efficiently than looping in javascript.

I realize that the original question was a CSS question so this answer is probably completely irrelevant, but other Javascript users may stumble on the question via search like I did.

Since nobody posted this, I am posting the correct answer. If your new state update depends on the previous state, always use the functional form of setState which accepts as argument a function that returns a new state.

In your case:

this.setState(prevState => ({
  check: !prevState.check
}));

See docs

Since this answer is becoming popular, adding the approach that should be used for React Hooks (v16.8+):

If you are using the useState hook, then use the following code (in case your new state depends on the previous state):

const [check, setCheck] = useState(false);
// ...
setCheck(prevCheck => !prevCheck);

A secondary option would be to match and return non-digits with some expression similar to,

/\D+/g

which would likely work for that specific string in the question (1 ding ?).

Demo

Test

function non_digit_string(str) {_x000D_
 const regex = /\D+/g;_x000D_
 let m;_x000D_
_x000D_
 non_digit_arr = [];_x000D_
 while ((m = regex.exec(str)) !== null) {_x000D_
  // This is necessary to avoid infinite loops with zero-width matches_x000D_
  if (m.index === regex.lastIndex) {_x000D_
   regex.lastIndex++;_x000D_
  }_x000D_
_x000D_
_x000D_
  m.forEach((match, groupIndex) => {_x000D_
   if (match.trim() != '') {_x000D_
    non_digit_arr.push(match.trim());_x000D_
   }_x000D_
  });_x000D_
 }_x000D_
 return non_digit_arr;_x000D_
}_x000D_
_x000D_
const str = `1 ding ? 124_x000D_
12 ding ?_x000D_
123 ding ? 123`;_x000D_
console.log(non_digit_string(str));

If you wish to simplify/modify/explore the expression, it's been explained on the top right panel of regex101.com. If you'd like, you can also watch in this link, how it would match against some sample inputs.

I use stanford nlp to perform lemmatization. I have been stuck up with a similar problem in the last few days. All thanks to stackoverflow to help me solve the issue .

import java.util.*; 
import edu.stanford.nlp.pipeline.*;
import edu.stanford.nlp.ling.*; 
import edu.stanford.nlp.ling.CoreAnnotations.*;  

public class example
{
    public static void main(String[] args)
    {
        Properties props = new Properties(); 
        props.put("annotators", "tokenize, ssplit, pos, lemma"); 
        pipeline = new StanfordCoreNLP(props, false);
        String text = /* the string you want */; 
        Annotation document = pipeline.process(text);  

        for(CoreMap sentence: document.get(SentencesAnnotation.class))
        {    
            for(CoreLabel token: sentence.get(TokensAnnotation.class))
            {       
                String word = token.get(TextAnnotation.class);      
                String lemma = token.get(LemmaAnnotation.class);

It also might be a good idea to use stopwords to minimize output lemmas if it's used later in classificator. Please take a look at coreNlp extension written by John Conwell.

Here's a simple circle_background.xml for pre-material:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape android:shape="oval">

You can use with the attribute 'android:background="@drawable/circle_background" in your button's layout definition

CMake produces Visual Studio Projects and Solutions seamlessly. You can even produce projects/solutions for different Visual Studio versions without making any changes to the CMake files.

Adding and removing source files is just a matter of modifying the CMakeLists.txt which has the list of source files and regenerating the projects/solutions. There is even a globbing function to find all the sources in a directory (though it should be used with caution).

The following link explains CMake and Visual Studio specific behavior very well.

CMake and Visual Studio

An iterative function to free your list:

void freeList(struct node* head)
{
   struct node* tmp;

   while (head != NULL)
    {
       tmp = head;
       head = head->next;
       free(tmp);
    }

}

What the function is doing is the follow:

1. check if head is NULL, if yes the list is empty and we just return

2. Save the head in a tmp variable, and make head point to the next node on your list (this is done in head = head->next

3. Now we can safely free(tmp) variable, and head just points to the rest of the list, go back to step 1

The way that Magento themes handle actual url's is as such (in view partials - phtml files):

echo $this->getSkinUrl('images/logo.png');

If you need the actual base path on disk to the image directory use:

echo Mage::getBaseDir('skin');

Some more base directory types are available in this great blog post:

http://alanstorm.com/magento_base_directories

From the Developer Guide:

android:id="@+id/my_button"

The at-symbol (@) at the beginning of the string indicates that the XML parser should parse and expand the rest of the ID string and identify it as an ID resource. The plus-symbol (+) means that this is a new resource name that must be created and added to our resources (in the R.java file). There are a number of other ID resources that are offered by the Android framework. When referencing an Android resource ID, you do not need the plus-symbol, but must add the android package namespace, like so:

android:id="@android:id/empty"

The main differences between InnoDB and MyISAM ("with respect to designing a table or database" you asked about) are support for "referential integrity" and "transactions".

If you need the database to enforce foreign key constraints, or you need the database to support transactions (i.e. changes made by two or more DML operations handled as single unit of work, with all of the changes either applied, or all the changes reverted) then you would choose the InnoDB engine, since these features are absent from the MyISAM engine.

Those are the two biggest differences. Another big difference is concurrency. With MyISAM, a DML statement will obtain an exclusive lock on the table, and while that lock is held, no other session can perform a SELECT or a DML operation on the table.

Those two specific engines you asked about (InnoDB and MyISAM) have different design goals. MySQL also has other storage engines, with their own design goals.

So, in choosing between InnoDB and MyISAM, the first step is in determining if you need the features provided by InnoDB. If not, then MyISAM is up for consideration.

A more detailed discussion of differences is rather impractical (in this forum) absent a more detailed discussion of the problem space... how the application will use the database, how many tables, size of the tables, the transaction load, volumes of select, insert, updates, concurrency requirements, replication features, etc.

The logical design of the database should be centered around data analysis and user requirements; the choice to use a relational database would come later, and even later would the choice of MySQL as a relational database management system, and then the selection of a storage engine for each table.

If you are using hand inputted data, you can enter your data as mm:ss,0 or mm:ss.0 depending on your language/region selection instead of 00:mm:ss.

You need to specify your cell format as [m]:ss if you like to see all minutes seconds format instead of hours minutes seconds format.

You should use sum:

Total = df['MyColumn'].sum()
print (Total)
319

Then you use loc with Series, in that case the index should be set as the same as the specific column you need to sum:

df.loc['Total'] = pd.Series(df['MyColumn'].sum(), index = ['MyColumn'])
print (df)
         X  MyColumn      Y      Z
0        A      84.0   13.0   69.0
1        B      76.0   77.0  127.0
2        C      28.0   69.0   16.0
3        D      28.0   28.0   31.0
4        E      19.0   20.0   85.0
5        F      84.0  193.0   70.0
Total  NaN     319.0    NaN    NaN

because if you pass scalar, the values of all rows will be filled:

df.loc['Total'] = df['MyColumn'].sum()
print (df)
         X  MyColumn      Y      Z
0        A        84   13.0   69.0
1        B        76   77.0  127.0
2        C        28   69.0   16.0
3        D        28   28.0   31.0
4        E        19   20.0   85.0
5        F        84  193.0   70.0
Total  319       319  319.0  319.0

Two other solutions are with at, and ix see the applications below:

df.at['Total', 'MyColumn'] = df['MyColumn'].sum()
print (df)
         X  MyColumn      Y      Z
0        A      84.0   13.0   69.0
1        B      76.0   77.0  127.0
2        C      28.0   69.0   16.0
3        D      28.0   28.0   31.0
4        E      19.0   20.0   85.0
5        F      84.0  193.0   70.0
Total  NaN     319.0    NaN    NaN

df.ix['Total', 'MyColumn'] = df['MyColumn'].sum()
print (df)
         X  MyColumn      Y      Z
0        A      84.0   13.0   69.0
1        B      76.0   77.0  127.0
2        C      28.0   69.0   16.0
3        D      28.0   28.0   31.0
4        E      19.0   20.0   85.0
5        F      84.0  193.0   70.0
Total  NaN     319.0    NaN    NaN

Note: Since Pandas v0.20, ix has been deprecated. Use loc or iloc instead.

Try this. Simple yet effective javaScript + jQuery the lethal combo.

SelectComponent :

<select id="YourSelectComponentID">
            <option value="0">Apple</option>
            <option value="2">Banana</option>
            <option value="3">Cat</option>
            <option value="4">Dolphin</option>
</select>

Selection :

document.getElementById("YourSelectComponentID").value = 4;

Now your option 4 will be selected. You can do this, to select the values on start by default.

$(function(){
   document.getElementById("YourSelectComponentID").value = 4;
});

or create a simple function put the line in it and call the function on anyEvent to select the option

A mixture of jQuery + javaScript does the magic....

If you need a simple working solution, try using DefaultTableModel.

If you have created your own table model, that extends AbstractTableModel, then you should also implement removeRow() method. The exact implementation depends on the underlying structure, that you have used to store data.

For example, if you have used Vector, then it may be something like this:

public class SimpleTableModel extends AbstractTableModel {
    private Vector<String> columnNames = new Vector<String>();
    // Each value in the vector is a row; String[] - row data;
    private Vector<String[]> data = new Vector<String[]>();

    ...

    public String getValueAt(int row, int col) {
        return data.get(row)[col];
    }

    ...

    public void removeRow(int row) {
        data.removeElementAt(row);
    }
}

If you have used List, then it would be very much alike:

// Each item in the list is a row; String[] - row data;
List<String[]> arr = new ArrayList<String[]>();

public void removeRow(int row) {
    data.remove(row);
}

HashMap:

//Integer - row number; String[] - row data;
HashMap<Integer, String[]> data = new HashMap<Integer, String[]>();

public void removeRow(Integer row) {
    data.remove(row);
}

And if you are using arrays like this one

String[][] data = { { "a", "b" }, { "c", "d" } };

then you're out of luck, because there is no way to dynamically remove elements from arrays. You may try to use arrays by storing separately some flags notifying which rows are deleted and which are not, or by some other devious way, but I would advise against it... That would introduce unnecessary complexity, and would in fact just be solving a problem by creating another. That's a sure-fire way to end up here. Try one of the above ways to store your table data instead.

For better understanding of how this works, and what to do to make your own model work properly, I strongly advise you to refer to Java Tutorial, DefaultTableModel API and it's source code.

The simple way to retrieve checked value of RadioButtonList1 is:

$('#RadioButtonList1 input:checked').val()

Edit by Tim:

where RadioButtonList1 must be the ClientID of the RadioButtonList

var rblSelectedValue = $("#<%= RadioButtonList1.ClientID %> input:checked"); 

DataSet myDataset = new DataSet();

DataTable customers = myDataset.Tables.Add("Customers");

customers.Columns.Add("Name");
customers.Columns.Add("Age");

customers.Rows.Add("Chris", "25");

//Get data
DataTable myCustomers = myDataset.Tables["Customers"];
DataRow currentRow = null;
for (int i = 0; i < myCustomers.Rows.Count; i++)
{
    currentRow = myCustomers.Rows[i];
    listBox1.Items.Add(string.Format("{0} is {1} YEARS OLD", currentRow["Name"], currentRow["Age"]));    
}

[UPDATED privacy keys list to iOS 13 - see below]

There is a list of all Cocoa Keys that you can specify in your Info.plist file:

https://developer.apple.com/library/content/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html

(Xcode: Target -> Info -> Custom iOS Target Properties)

iOS already required permissions to access microphone, camera, and media library earlier (iOS 6, iOS 7), but since iOS 10 app will crash if you don't provide the description why you are asking for the permission (it can't be empty).

Privacy keys with example description:

Source

Alternatively, you can open Info.plist as source code:

Source

And add privacy keys like this:

<key>NSLocationAlwaysUsageDescription</key>
<string>${PRODUCT_NAME} always location use</string>

List of all privacy keys: [UPDATED to iOS 13]

Update 2019:

In the last months, two of my apps were rejected during the review because the camera usage description wasn't specifying what I do with taken photos.

I had to change the description from ${PRODUCT_NAME} need access to the camera to take a photo to ${PRODUCT_NAME} need access to the camera to update your avatar even though the app context was obvious (user tapped on the avatar).

It seems that Apple is now paying even more attention to the privacy usage descriptions, and we should explain in details why we are asking for permission.

I use the following, it also tests the extension which means it can be used for testing if the path supplied is a file but a file that doesn't exist.

private static bool isDirectory(string path)
{
    bool result = true;
    System.IO.FileInfo fileTest = new System.IO.FileInfo(path);
    if (fileTest.Exists == true)
    {
        result = false;
    }
    else
    {
        if (fileTest.Extension != "")
        {
            result = false;
        }
    }
    return result;
}

It's "a reference to the object in the current context" effectively. For example, to print out "this object" you might write:

System.out.println(this);

Note that your usage of "global variable" is somewhat off... if you're using this.variableName then by definition it's not a global variable - it's a variable specific to this particular instance.

Link to the PyYAML documentation showing the difference for the default_flow_style parameter. To write it to a file in block mode (often more readable):

d = {'A':'a', 'B':{'C':'c', 'D':'d', 'E':'e'}}
with open('result.yml', 'w') as yaml_file:
    yaml.dump(d, yaml_file, default_flow_style=False)

produces:

A: a
B:
  C: c
  D: d
  E: e

Solved myself. Done some small structural changes also. Route from Component1 to Component2 is done by a single <router-outlet>. Component2 to Comonent3 and Component4 is done by multiple <router-outlet name= "xxxxx"> The resulting contents are :

Component1.html

<nav>
    <a routerLink="/two" class="dash-item">Go to 2</a>
</nav>
    <router-outlet></router-outlet>

Component2.html

 <a [routerLink]="['/two', {outlets: {'nameThree': ['three']}}]">In Two...Go to 3 ...       </a>
 <a [routerLink]="['/two', {outlets: {'nameFour': ['four']}}]">   In Two...Go to 4 ...</a>

 <router-outlet name="nameThree"></router-outlet>
 <router-outlet name="nameFour"></router-outlet>

The '/two' represents the parent component and ['three']and ['four'] represents the link to the respective children of component2 . Component3.html and Component4.html are the same as in the question.

router.module.ts

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [

        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree'
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        }
    ]
},];

You can do this by adding a div i.e. centerBlock. And give this property in CSS to center the image or any content. Here is the code:

<div class="container">
    <div class="row">
        <div class="col-sm-4 col-md-4 col-lg-4">
            <div class="centerBlock">
                <img class="img-responsive" src="img/some-image.png" title="This image needs to be centered">
            </div>
        </div>
        <div class="col-sm-8 col-md-8 col-lg-8">
            Some content not important at this moment
        </div>
    </div>
</div>


// CSS

.centerBlock {
  display: table;
  margin: auto;
}

Use an inner join instead:

SELECT ...
FROM SomeTable
JOIN
(SELECT 'bla%' AS Pattern 
UNION ALL SELECT '%foo%'
UNION ALL SELECT 'batz%'
UNION ALL SELECT 'abc'
) AS Patterns
ON SomeTable.SomeColumn LIKE Patterns.Pattern

If you want to store your output into your desktop, follow the below command using post command in git bash.It worked for me.

curl https://localhost:8080 --request POST --header "Content-Type: application/json" -o "C:\Desktop\test.txt"

you can read empList directly in forEach tag.Try this

 <table>
       <c:forEach items="${sessionScope.empList}" var="employee">
            <tr>
                <td>Employee ID: <c:out value="${employee.eid}"/></td>
                <td>Employee Pass: <c:out value="${employee.ename}"/></td>  
            </tr>
        </c:forEach>
    </table>

A header (.h, .hpp, ...) file contains

• Class definitions ( class X { ... }; )
• Inline function definitions ( inline int get_cpus() { ... } )
• Function declarations ( void help(); )
• Object declarations ( extern int debug_enabled; )

A source file (.c, .cpp, .cxx) contains

• Function definitions ( void help() { ... } or void X::f() { ... } )
• Object definitions ( int debug_enabled = 1; )

However, the convention that headers are named with a .h suffix and source files are named with a .cpp suffix is not really required. One can always tell a good compiler how to treat some file, irrespective of its file-name suffix ( -x <file-type> for gcc. Like -x c++ ).

Source files will contain definitions that must be present only once in the whole program. So if you include a source file somewhere and then link the result of compilation of that file and then the one of the source file itself together, then of course you will get linker errors, because you have those definitions now appear twice: Once in the included source file, and then in the file that included it. That's why you had problems with including the .cpp file.

You just need to have the full expression inside the $. Basically, you need "meters $10^1$". You don't need usetex=True to do this (or most any mathematical formula).

You may also want to use a raw string (e.g. r"\t", vs "\t") to avoid problems with things like \n, \a, \b, \t, \f, etc.

For example:

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.set(title=r'This is an expression $e^{\sin(\omega\phi)}$',
       xlabel='meters $10^1$', ylabel=r'Hertz $(\frac{1}{s})$')
plt.show()

If you don't want the superscripted text to be in a different font than the rest of the text, use \mathregular (or equivalently \mathdefault). Some symbols won't be available, but most will. This is especially useful for simple superscripts like yours, where you want the expression to blend in with the rest of the text.

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.set(title=r'This is an expression $\mathregular{e^{\sin(\omega\phi)}}$',
       xlabel='meters $\mathregular{10^1}$',
       ylabel=r'Hertz $\mathregular{(\frac{1}{s})}$')
plt.show()

For more information (and a general overview of matplotlib's "mathtext"), see: http://matplotlib.org/users/mathtext.html

",".join(l) will not work for all cases. I'd suggest using the csv module with StringIO

import StringIO
import csv

l = ['list','of','["""crazy"quotes"and\'',123,'other things']

line = StringIO.StringIO()
writer = csv.writer(line)
writer.writerow(l)
csvcontent = line.getvalue()
# 'list,of,"[""""""crazy""quotes""and\'",123,other things\r\n'

In case you need more shorting your code, you can creating new type for helper

type Strings []string

func (ss Strings) ToInterfaceSlice() []interface{} {
    iface := make([]interface{}, len(ss))
    for i := range ss {
        iface[i] = ss[i]
    }
    return iface
}

then

a := []strings{"a", "b", "c", "d"}
sliceIFace := Strings(a).ToInterfaceSlice()

Few years later, I've built this library to do drop files into any HTML element.

You can use it like

const Droppable = require('droppable');

const droppable = new Droppable({
    element: document.querySelector('#my-droppable-element')
})

droppable.onFilesDropped((files) => {
    console.log('Files were dropped:', files);
});

// Clean up when you're done!
droppable.destroy();

Nowadays people are just using CSS3 transitions because it's a lot easier than messing with JS, browser support is reasonably good and it's merely cosmetic so it doesn't matter if it doesn't work.

Something like this gets the job done:

a {
  color:blue;

  -ms-transition:color .2s ease-out, background 1s ease-in;

  -webkit-transition:color .2s ease-out, background 1s ease-in;
  /* ...and now override with proper CSS property */
  transition:color .2s ease-out, background 1s ease-in;

a:hover { color:red; background:yellow; }

It's possible to use wrapper which runs selected or all tests.

For instance:

./run_tests antigravity/*.py

or to run all tests recursively use globbing (tests/**/*.py) (enable by shopt -s globstar).

The wrapper can basically use argparse to parse the arguments like:

parser = argparse.ArgumentParser()
parser.add_argument('files', nargs='*')

Then load all the tests:

for filename in args.files:
    exec(open(filename).read())

then add them into your test suite (using inspect):

alltests = unittest.TestSuite()
for name, obj in inspect.getmembers(sys.modules[__name__]):
    if inspect.isclass(obj) and name.startswith("FooTest"):
        alltests.addTest(unittest.makeSuite(obj))

and run them:

result = unittest.TextTestRunner(verbosity=2).run(alltests)

Check this example for more details.

I'm using Git 1.5.4.3 and it's following the passed symlink if it has a trailing slash. E.g.

# Adds the symlink itself
$ git add symlink

# Follows symlink and adds the denoted directory's contents
$ git add symlink/

I converted the pandas dataframe to list and then used the basic list.index(). Something like this:

dd = list(zone[0]) #Where zone[0] is some specific column of the table
idx = dd.index(filename[i])

You have you index value as idx.

You could put a _ViewStart.cshtml file inside the /Views/Public folder which would override the default one in the /Views folder and specify the desired layout:

@{
    Layout = "~/Views/Shared/_PublicLayout.cshtml";
}

By analogy you could put another _ViewStart.cshtml file inside the /Views/Staff folder with:

@{
    Layout = "~/Views/Shared/_StaffLayout.cshtml";
}

You could also specify which layout should be used when returning a view inside a controller action but that's per action:

return View("Index", "~/Views/Shared/_StaffLayout.cshtml", someViewModel);

Yet another possibility is a custom action filter which would override the layout. As you can see many possibilities to achieve this. Up to you to choose which one fits best in your scenario.

UPDATE:

As requested in the comments section here's an example of an action filter which would choose a master page:

public class LayoutInjecterAttribute : ActionFilterAttribute
{
    private readonly string _masterName;
    public LayoutInjecterAttribute(string masterName)
    {
        _masterName = masterName;
    }

    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        base.OnActionExecuted(filterContext);
        var result = filterContext.Result as ViewResult;
        if (result != null)
        {
            result.MasterName = _masterName;
        }
    }
}

and then decorate a controller or an action with this custom attribute specifying the layout you want:

[LayoutInjecter("_PublicLayout")]
public ActionResult Index()
{
    return View();
}

Here's my code for it:

packages <- c("dplyr", "gridBase", "gridExtra")
package_loader <- function(x){
    for (i in 1:length(x)){
        if (!identical((x[i], installed.packages()[x[i],1])){
            install.packages(x[i], dep = TRUE)
        } else {
            require(x[i], character.only = TRUE)
        }
    }
}
package_loader(packages)

It sounds like your printMousePos function should:

1. Get the X and Y coordinates of the mouse
2. Add those values to the HTML

Currently, it does this:

1. Creates (undefined) variables for the X and Y coordinates of the mouse
2. Attaches a function to the "mousemove" event (which will set those variables to the mouse coordinates when triggered by a mouse move)
3. Adds the current values of your variables to the HTML

See the problem? Your variables are never getting set, because as soon as you add your function to the "mousemove" event you print them.

It seems like you probably don't need that mousemove event at all; I would try something like this:

function printMousePos(e) {
    var cursorX = e.pageX;
    var cursorY = e.pageY;
    document.getElementById('test').innerHTML = "x: " + cursorX + ", y: " + cursorY;
}

This is the simplest workaround I could think of.

<span ng-repeat="n in [].constructor(5) track by $index">
{{$index}}
</span>

Here's a Plunker example.

Eugen's answer didn't quite work for me but this did:

    absolute="$(cd $(dirname \"$file\"); pwd)/$(basename \"$file\")"

Side note, your current working directory is unaffected.

In your case, "EOF" is known as a "Here Tag". Basically <<Here tells the shell that you are going to enter a multiline string until the "tag" Here. You can name this tag as you want, it's often EOF or STOP.

Some rules about the Here tags:

1. The tag can be any string, uppercase or lowercase, though most people use uppercase by convention.
2. The tag will not be considered as a Here tag if there are other words in that line. In this case, it will merely be considered part of the string. The tag should be by itself on a separate line, to be considered a tag.
3. The tag should have no leading or trailing spaces in that line to be considered a tag. Otherwise it will be considered as part of the string.

example:

$ cat >> test <<HERE
> Hello world HERE <-- Not by itself on a separate line -> not considered end of string
> This is a test
>  HERE <-- Leading space, so not considered end of string
> and a new line
> HERE <-- Now we have the end of the string

In my case , I've some codes which needs to execute after committing the transaction at the same try catch block.One of the code threw an error then try block handed over the error to it's catch block which contains the transaction rollback. It will show the similar error. For example look at the code structure below :

SqlTransaction trans = null;

try{
 trans = Con.BeginTransaction();
// your codes

  trans.Commit();
//your codes having errors

}
catch(Exception ex)
{
     trans.Rollback(); //transaction roll back
    // error message
}

finally
{ 
    // connection close
}

Hope it will someone :)

about theutz answer , there is no need to specify the IMapper mapper parrameter at the controllers constructor.

you can use the Mapper as it is a static member at any place of the code.

public class UserController : Controller {
   public someMethod()
   {
      Mapper.Map<User, UserDto>(user);
   }
}

  border-color: #000 transparent transparent transparent;_x000D_

Instead of detecting the keyboard, try to detect the size of the window

If the height of the window was reduced, and the width is still the same, it means that the keyboard is on. Else the keyboard is off, you can also add to that, test if any input field is on focus or not.

Try this code for example.

var last_h = $(window).height(); //  store the intial height.
var last_w = $(window).width(); //  store the intial width.
var keyboard_is_on = false;
$(window).resize(function () {
    if ($("input").is(":focus")) {
        keyboard_is_on =
               ((last_w == $(window).width()) && (last_h > $(window).height()));
    }   
});     

Try the following:

gradle -Dhttp.proxyHost=yourProxy -Dhttp.proxyPort=yourPort -Dhttp.proxyUser=usernameProxy -Dhttp.proxyPassword=yourPassoword

Understanding the available syntaxes of arrow functions will give you an understanding of what behaviour they are introducing when 'chained' like in the examples you provided.

When an arrow function is written without block braces, with or without multiple parameters, the expression that constitutes the function's body is implicitly returned. In your example, that expression is another arrow function.

No arrow funcs              Implicitly return `e=>{…}`    Explicitly return `e=>{…}` 
---------------------------------------------------------------------------------
function (field) {         |  field => e => {            |  field => {
  return function (e) {    |                             |    return e => {
      e.preventDefault()   |    e.preventDefault()       |      e.preventDefault()
  }                        |                             |    }
}                          |  }                          |  }

Another advantage of writing anonymous functions using the arrow syntax is that they are bound lexically to the scope in which they are defined. From 'Arrow functions' on MDN:

An arrow function expression has a shorter syntax compared to function expressions and lexically binds the this value. Arrow functions are always anonymous.

This is particularly pertinent in your example considering that it is taken from a reactjs application. As as pointed out by @naomik, in React you often access a component's member functions using this. For example:

Unbound                     Explicitly bound            Implicitly bound 
------------------------------------------------------------------------------
function (field) {         |  function (field) {       |  field => e => {
  return function (e) {    |    return function (e) {  |    
      this.setState(...)   |      this.setState(...)   |    this.setState(...)
  }                        |    }.bind(this)           |    
}                          |  }.bind(this)             |  }

string Index = i;
            string FileName = "Mutton" + Index + ".xml";
            XmlDocument xmlDoc = new XmlDocument();

            var path = Path.Combine(Server.MapPath("~/Content/FilesXML"), FileName);
            xmlDoc.Load(path); // Can use xmlDoc.LoadXml(YourString);

this is the best Solution to get the path what is exactly need for now

I came across this because I just had problems creating a remote connection and couldn't understand why setting up 1433 port in firewall is not doing the job. I finally have the full picture now, so I thought I should share.

First of all is a must to enable "TCP/IP" using the SQL Server Configuration Manager under Protocols for SQLEXPRESS!

When a named instance is used ("SQLExpress" in this case), this will listen on a dynamic port. To find this dynamic port you have couple of options; to name a few:

• checking ERRORLOG of SQL Server located in '{MS SQL Server Path}\{MS SQL Server instance name}\MSSQL\Log' (inside you'll find a line similar to this: "2013-07-25 10:30:36.83 Server Server is listening on [ 'any' <ipv4> 51118]" --> so 51118 is the dynamic port in this case.

• checking registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\{MSSQL instance name}\MSSQLServer\SuperSocketNetLib\Tcp\IPAll, for my case TcpDynamicPorts=51118.

  Edit: {MSSQL instance name} is something like: MSSQL10_50.SQLEXPRESS, not only SQLEXPRESS

Of course, allowing this TCP port in firewall and creating a remote connection by passing in: "x.x.x.x,51118" (where x.x.x.x is the server ip) already solves it at this point.

But then I wanted to connect remotely by passing in the instance name (e.g: x.x.x.x\SQLExpress). This is when SQL Browser service comes into play. This is the unit which resolves the instance name into the 51118 port. SQL Browser service listens on UDP port 1434 (standard & static), so I had to allow this also in server's firewall.

To extend a bit the actual answer: if someone else doesn't like dynamic ports and wants a static port for his SQL Server instance, should try this link.

According to the documentation you can simply return false; to break:

$(xml).find("strengths").each(function() {

    if (iWantToBreak)
        return false;
});

You should set android:button="@null" instead of "null".

You were soo close!

Element needs to be a variant, so you can't declare it as a string. Your function should accept a variant if it is a string though as long as you pass it ByVal.

Public Sub example()
    Dim sArray(4) As string
    Dim element As variant

    For Each element In sArray
        do_something (element)
    Next element
End Sub


Sub do_something(ByVal e As String)

End Sub

The other option is to convert the variant to a string before passing it.

  do_something CStr(element)

In your version rand() % 10000 will yield an integer between 0 and 9999. Since RAND_MAX may be as little as 32767, and since this is not exactly divisible by 10000 and not large relative to 10000, there will be significant bias in the 'randomness' of the result, moreover, the maximum value will be 0.9999, not 1.0, and you have unnecessarily restricted your values to four decimal places.

It is simple arithmetic, a random number divided by the maximum possible random number will yield a number from 0 to 1 inclusive, while utilising the full resolution and distribution of the RNG

double r2()
{
    return (double)rand() / (double)RAND_MAX ;
}

Use (double)rand() / (double)((unsigned)RAND_MAX + 1) if exclusion of 1.0 was intentional.

In <body> you should have two <script> tags:

<script src="https://code.jquery.com/jquery-2.1.3.js"></script>
<script src="js/bootstrap.js"></script>

The first one will load jQuery from the CDN, and second one will load Bootstrap's Javascript from a local directory (in this case it's a directory called js).

You could use the n-th child selector.

to target the nth element you could then use:

td:nth-child(n) {  
  /* your stuff here */
}

(where n starts at 1)

Math.round(number*100.0)/100.0;

If your div is an ASP.NET control with runat="server" then AviewAnew's answer should do it. If it's just an HTML div, then you'd probably want to use JavaScript. Can you add the actual div tag to your question?
