LLVM (used to mean "Low Level Virtual Machine" but not anymore) is a compiler infrastructure, written in C++, which is designed for compile-time, link-time, run-time, and "idle-time" optimization of programs written in arbitrary programming languages. Originally implemented for C/C++, the language-independent design (and the success) of LLVM has since spawned a wide variety of front-ends, including Objective C, Fortran, Ada, Haskell, Java bytecode, Python, Ruby, ActionScript, GLSL, and others.

Slight modification of the solution above so it works with variable-length delimiters.

create FUNCTION dbo.fn_Split2 (@sep nvarchar(10), @s nvarchar(4000))
RETURNS table
AS
RETURN (
    WITH Pieces(pn, start, stop) AS (
      SELECT 1, 1, CHARINDEX(@sep, @s)
      UNION ALL
      SELECT pn + 1, stop + (datalength(@sep)/2), CHARINDEX(@sep, @s, stop + (datalength(@sep)/2))
      FROM Pieces
      WHERE stop > 0
    )
    SELECT pn,
      SUBSTRING(@s, start, CASE WHEN stop > 0 THEN stop-start ELSE 4000 END) AS s
    FROM Pieces
  )

NB: I've used datalength() since len() reports incorrectly if there are trailing spaces.

I think this suits perfect for any color you have:

a {
    color: inherit;
}

Had the same problem (is not a method) with jQuery when working on autocomplete. It appeared the code was executed before the autocomplete.js was loaded. So make sure the ui.colorpicker.js is loaded before calling colorpicker.

cols = list(df.columns.values) #Make a list of all of the columns in the df
cols.pop(cols.index('b')) #Remove b from list
cols.pop(cols.index('x')) #Remove x from list
df = df[cols+['b','x']] #Create new dataframe with columns in the order you want

Another Solution : you get the marker by its title

public class MarkerDemoActivity extends android.support.v4.app.FragmentActivity implements OnMarkerClickListener
{
      private Marker myMarker;    

      private void setUpMap()
      {
      .......
      googleMap.setOnMarkerClickListener(this);

      myMarker = googleMap.addMarker(new MarkerOptions()
                  .position(latLng)
                  .title("My Spot")
                  .snippet("This is my spot!")
                  .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
      ......
      }

  @Override
  public boolean onMarkerClick(final Marker marker) 
  {

     String name= marker.getTitle();

      if (name.equalsIgnoreCase("My Spot")) 
      {
          //write your code here
      }
  }
}

select partition_name,column_name,high_value,partition_position
from ALL_TAB_PARTITIONS a , ALL_PART_KEY_COLUMNS b 
where table_name='YOUR_TABLE' and a.table_name = b.name;

This query lists the column name used as key and the allowed values. make sure, you insert the allowed values(high_value). Else, if default partition is defined, it would go there.

EDIT:

I presume, your TABLE DDL would be like this.

CREATE TABLE HE0_DT_INF_INTERFAZ_MES
  (
    COD_PAIS NUMBER,
    FEC_DATA NUMBER,
    INTERFAZ VARCHAR2(100)
  )
  partition BY RANGE(COD_PAIS, FEC_DATA)
  (
    PARTITION PDIA_98_20091023 VALUES LESS THAN (98,20091024)
  );

Which means I had created a partition with multiple columns which holds value less than the composite range (98,20091024);

That is first COD_PAIS <= 98 and Also FEC_DATA < 20091024

Combinations And Result:

98, 20091024     FAIL
98, 20091023     PASS
99, ********     FAIL
97, ********     PASS
 < 98, ********     PASS

So the below INSERT fails with ORA-14400; because (98,20091024) in INSERT is EQUAL to the one in DDL but NOT less than it.

SQL> INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
                                  VALUES(98, 20091024, 'CTA');  2
INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
            *
ERROR at line 1:
ORA-14400: inserted partition key does not map to any partition

But, we I attempt (97,20091024), it goes through

SQL> INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
  2                                    VALUES(97, 20091024, 'CTA');

1 row created.

There's no ALTER COLUMN in sqlite.

I believe your only option is to:

• Rename the table to a temporary name
• Create a new table without the NOT NULL constraint
• Copy the content of the old table to the new one
• Remove the old table

This other Stackoverflow answer explains the process in details

This example uses Bash's built-in getopts command and is from the Google Shell Style Guide:

a_flag=''
b_flag=''
files=''
verbose='false'

print_usage() {
  printf "Usage: ..."
}

while getopts 'abf:v' flag; do
  case "${flag}" in
    a) a_flag='true' ;;
    b) b_flag='true' ;;
    f) files="${OPTARG}" ;;
    v) verbose='true' ;;
    *) print_usage
       exit 1 ;;
  esac
done

Note: If a character is followed by a colon (e.g. f:), that option is expected to have an argument.

Example usage: ./script -v -a -b -f filename

Using getopts has several advantages over the accepted answer:

• the while condition is a lot more readable and shows what the accepted options are
• cleaner code; no counting the number of parameters and shifting
• you can join options (e.g. -a -b -c ? -abc)

However, a big disadvantage is that it doesn't support long options, only single-character options.

You can set up a express proxy server using http-proxy-middleware to bypass CORS:

const express = require('express');
const proxy = require('http-proxy-middleware');
const path = require('path');
const port = process.env.PORT || 8080;
const app = express();

app.use(express.static(__dirname));
app.use('/proxy', proxy({
    pathRewrite: {
       '^/proxy/': '/'
    },
    target: 'https://server.com',
    secure: false
}));

app.get('*', (req, res) => {
   res.sendFile(path.resolve(__dirname, 'index.html'));
});

app.listen(port);
console.log('Server started');

From your react app all requests should be sent to /proxy endpoint and they will be redirected to the intended server.

const URL = `/proxy/${PATH}`;
return axios.get(URL);

How to mock void methods with mockito - there are two options:

1. doAnswer - If we want our mocked void method to do something (mock the behavior despite being void).
2. doThrow - Then there is Mockito.doThrow() if you want to throw an exception from the mocked void method.

Following is an example of how to use it (not an ideal usecase but just wanted to illustrate the basic usage).

@Test
public void testUpdate() {

    doAnswer(new Answer<Void>() {

        @Override
        public Void answer(InvocationOnMock invocation) throws Throwable {
            Object[] arguments = invocation.getArguments();
            if (arguments != null && arguments.length > 1 && arguments[0] != null && arguments[1] != null) {

                Customer customer = (Customer) arguments[0];
                String email = (String) arguments[1];
                customer.setEmail(email);

            }
            return null;
        }
    }).when(daoMock).updateEmail(any(Customer.class), any(String.class));

    // calling the method under test
    Customer customer = service.changeEmail("[email protected]", "[email protected]");

    //some asserts
    assertThat(customer, is(notNullValue()));
    assertThat(customer.getEmail(), is(equalTo("[email protected]")));

}

@Test(expected = RuntimeException.class)
public void testUpdate_throwsException() {

    doThrow(RuntimeException.class).when(daoMock).updateEmail(any(Customer.class), any(String.class));

    // calling the method under test
    Customer customer = service.changeEmail("[email protected]", "[email protected]");

}
}

Tried and working. you are using,

<textarea name='Status'> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>

I am using javascript , (don't know about php), use id ="status" in textarea like

<textarea name='Status' id="status"> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>

then make a call to servlet sending the status to backend for updating using whatever strutucre(like MVC in java or anyother) you like, like this in your UI in script tag

<srcipt>
function UpdateStatus(){

//make an ajax call and get status value using the same 'id'
var var1= document.getElementById("status").value;
$.ajax({

        type:"GET",//or POST
        url:'http://localhost:7080/ajaxforjson/Testajax',
                           //  (or whatever your url is)
        data:{data1:var1},
        //can send multipledata like {data1:var1,data2:var2,data3:var3
        //can use dataType:'text/html' or 'json' if response type expected 
        success:function(responsedata){
               // process on data
               alert("got response as "+"'"+responsedata+"'");

        }
     })

}
</script>

and jsp is like

the servlet will look like:   //webservlet("/zcvdzv") is just for url annotation
@WebServlet("/Testajax")

public class Testajax extends HttpServlet {
private static final long serialVersionUID = 1L;
public Testajax() {
    super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    String data1=request.getParameter("data1");
    //do processing on datas pass in other java class to add to DB
    // i am adding or concatenate
    String data="i Got : "+"'"+data1+"' ";
    System.out.println(" data1 : "+data1+"\n data "+data);
    response.getWriter().write(data);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    doGet(request, response);
}

}

You should use & / | operators and be careful about operator precedence (== has lower precedence than bitwise AND and OR):

df1 = sqlContext.createDataFrame(
    [(1, "a", 2.0), (2, "b", 3.0), (3, "c", 3.0)],
    ("x1", "x2", "x3"))

df2 = sqlContext.createDataFrame(
    [(1, "f", -1.0), (2, "b", 0.0)], ("x1", "x2", "x3"))

df = df1.join(df2, (df1.x1 == df2.x1) & (df1.x2 == df2.x2))
df.show()

## +---+---+---+---+---+---+
## | x1| x2| x3| x1| x2| x3|
## +---+---+---+---+---+---+
## |  2|  b|3.0|  2|  b|0.0|
## +---+---+---+---+---+---+

edit (not by the author): There is a comprehensive list of IoC frameworks available at https://github.com/quozd/awesome-dotnet/blob/master/README.md#ioc:

• Castle Windsor - Castle Windsor is best of breed, mature Inversion of Control container available for .NET and Silverlight
• Unity - Lightweight extensible dependency injection container with support for constructor, property, and method call injection
• Autofac - An addictive .NET IoC container
• DryIoc - Simple, fast all fully featured IoC container.
• Ninject - The ninja of .NET dependency injectors
• StructureMap - The original IoC/DI Container for .Net
• Spring.Net - Spring.NET is an open source application framework that makes building enterprise .NET applications easier
• LightInject - A ultra lightweight IoC container
• Simple Injector - Simple Injector is an easy-to-use Dependency Injection (DI) library for .NET 4+ that supports Silverlight 4+, Windows Phone 8, Windows 8 including Universal apps and Mono.
• Microsoft.Extensions.DependencyInjection - The default IoC container for ASP.NET Core applications.
• Scrutor - Assembly scanning extensions for Microsoft.Extensions.DependencyInjection.
• VS MEF - Managed Extensibility Framework (MEF) implementation used by Visual Studio.
• TinyIoC - An easy to use, hassle free, Inversion of Control Container for small projects, libraries and beginners alike.

Original answer follows.

I suppose I might be being a bit picky here but it's important to note that DI (Dependency Injection) is a programming pattern and is facilitated by, but does not require, an IoC (Inversion of Control) framework. IoC frameworks just make DI much easier and they provide a host of other benefits over and above DI.

That being said, I'm sure that's what you were asking. About IoC Frameworks; I used to use Spring.Net and CastleWindsor a lot, but the real pain in the behind was all that pesky XML config you had to write! They're pretty much all moving this way now, so I have been using StructureMap for the last year or so, and since it has moved to a fluent config using strongly typed generics and a registry, my pain barrier in using IoC has dropped to below zero! I get an absolute kick out of knowing now that my IoC config is checked at compile-time (for the most part) and I have had nothing but joy with StructureMap and its speed. I won't say that the others were slow at runtime, but they were more difficult for me to setup and frustration often won the day.

Update

I've been using Ninject on my latest project and it has been an absolute pleasure to use. Words fail me a bit here, but (as we say in the UK) this framework is 'the Dogs'. I would highly recommend it for any green fields projects where you want to be up and running quickly. I got all I needed from a fantastic set of Ninject screencasts by Justin Etheredge. I can't see that retro-fitting Ninject into existing code being a problem at all, but then the same could be said of StructureMap in my experience. It'll be a tough choice going forward between those two, but I'd rather have competition than stagnation and there's a decent amount of healthy competition out there.

Other IoC screencasts can also be found here on Dimecasts.

None of that stuff worked. Here's a much simpler way .. the label str is the pointer to what IS an array...

String str = String(yourNumber, DEC); // Obviously .. get your int or byte into the string

str = str + '\r' + '\n'; // Add the required carriage return, optional line feed

byte str_len = str.length();

// Get the length of the whole lot .. C will kindly
// place a null at the end of the string which makes
// it by default an array[].
// The [0] element is the highest digit... so we
// have a separate place counter for the array...

byte arrayPointer = 0;

while (str_len)
{
    // I was outputting the digits to the TX buffer

    if ((UCSR0A & (1<<UDRE0))) // Is the TX buffer empty?
    {
        UDR0 = str[arrayPointer];
        --str_len;
        ++arrayPointer;
    }
}

I faced the same question. I want to add some info to the user-agent, also need to keep the original user-agent of webview. I solved it by using the code below:

    //get the original user-agent of webview
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectZero];
NSString *oldAgent = [webView stringByEvaluatingJavaScriptFromString:@"navigator.userAgent"];
NSLog(@"old agent :%@", oldAgent);

//add my info to the new agent
NSString *newAgent = [oldAgent stringByAppendingString:@" Jiecao/2.4.7 ch_appstore"];
NSLog(@"new agent :%@", newAgent);

//regist the new agent
NSDictionary *dictionnary = [[NSDictionary alloc] initWithObjectsAndKeys:newAgent, @"UserAgent", nil];
[[NSUserDefaults standardUserDefaults] registerDefaults:dictionnary];

Use it before you instancing webview.

With the official Material Components library you can use the MaterialButton applying a Widget.MaterialComponents.Button.Icon style.

Something like:

   <com.google.android.material.button.MaterialButton
            android:layout_width="48dp"
            android:layout_height="48dp"
            style="@style/Widget.MaterialComponents.Button.Icon"
            app:icon="@drawable/ic_add"
            app:iconSize="24dp"
            app:iconPadding="0dp"
            android:insetLeft="0dp"
            android:insetTop="0dp"
            android:insetRight="0dp"
            android:insetBottom="0dp"
            app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.MyApp.Button.Rounded"
            />

Currently the app:iconPadding="0dp",android:insetLeft,android:insetTop,android:insetRight,android:insetBottom attributes are needed to center the icon on the button avoiding extra padding space.

Use the app:shapeAppearanceOverlay attribute to get rounded corners. In this case you will have a circle.

  <style name="ShapeAppearanceOverlay.MyApp.Button.Rounded" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">50%</item>
  </style>

The final result:

TLDR; Use an encrypted netrc file with Git 1.8.3+.

Saving a password for a Git repository HTTPS URL is possible with a ~/.netrc (Unix) or %HOME%/_netrc (note the _) on Windows.

But: That file would store your password in plain text.

Solution: Encrypt that file with GPG (GNU Privacy Guard), and make Git decrypt it each time it needs a password (for push/pull/fetch/clone operation).

Note: with Git 2.18 (Q2 2018), you now can customize the GPG used to decrypt the encrypted .netrc file.

git-credential-netrc: accept gpg option

git-credential-netrc was hardcoded to decrypt with 'gpg' regardless of the gpg.program option.
This is a problem on distributions like Debian that call modern GnuPG something else, like 'gpg2'

Step-by-Step instructions for Windows

With Windows:

(Git has a gpg.exe in its distribution, but using a full GPG installation includes a gpg-agent.exe, which will memorize your passphrase associated to your GPG key.)

• Install gpg4Win Lite, the minimum gnupg command-line interface (take the most recent gpg4win-vanilla-2.X.Y-betaZZ.exe), and complete your PATH with the GPG installation directory:

  set PATH=%PATH%:C:\path\to\gpg
  copy C:\path\to\gpg\gpg2.exe C:\path\to\gpg\gpg.exe
  

(Note the 'copy' command: Git will need a Bash script to execute the command 'gpg'. Since gpg4win-vanilla-2 comes with gpg2.exe, you need to duplicate it.)

• Create or import a GPG key, and trust it:

  gpgp --import aKey
  # or
  gpg --gen-key
  

(Make sure to put a passphrase to that key.)

• Trust that key

• Install the credential helper script in a directory within your %PATH%:

  cd c:\a\fodler\in\your\path
  curl -o c:\prgs\bin\git-credential-netrc https://raw.githubusercontent.com/git/git/master/contrib/credential/netrc/git-credential-netrc.perl
  

(Beware: the script is renamed in Git 2.25.x/2.26, see below)

(Yes, this is a Bash script, but it will work on Windows since it will be called by Git.)

• Make a _netrc file in clear text

  machine a_server.corp.com
  login a_login
  password a_password
  protocol https
  
  machine a_server2.corp.com
  login a_login2
  password a_password2
  protocol https
  

(Don't forget the 'protocol' part: 'http' or 'https' depending on the URL you will use.)

• Encrypt that file:

  gpg -e -r a_recipient _netrc
  

(You now can delete the _netrc file, keeping only the _netrc.gpg encrypted one.)

• Use that encrypted file:

  git config --local credential.helper "netrc -f C:/path/to/_netrc.gpg -v"
  

(Note the '/': C:\path\to... wouldn't work at all.) (You can use at first -v -d to see what is going on.)

From now on, any Git command using an HTTP(S) URL which requires authentication will decrypt that _netrc.gpg file and use the login/password associated to the server you are contacting. The first time, GPG will ask you for the passphrase of your GPG key, to decrypt the file. The other times, the gpg-agent launched automatically by the first GPG call will provide that passphrase for you.

That way, you can memorize several URLs/logins/passwords in one file, and have it stored on your disk encrypted.
I find it more convenient than a "cache" helper", where you need to remember and type (once per session) a different password for each of your remote services, for said password to be cached in memory.

With Git 2.26 (Q1 2020), the sample credential helper for using .netrc has been updated to work out of the box. See patch/discussion.

See commit 6579d93, commit 1c78c78 (20 Dec 2019) by Denton Liu (Denton-L).

contrib/credential/netrc: make PERL_PATH configurable

^{Signed-off-by: Denton Liu}

The shebang path for the Perl interpreter in git-credential-netrc was hardcoded.
However, some users may have it located at a different location and thus, would have had to manually edit the script.

Add a .perl prefix to the script to denote it as a template and ignore the generated version.
Augment the Makefile so that it generates git-credential-netrc from git-credential-netrc.perl, just like other Perl scripts.

The Makefile recipes were shamelessly stolen from contrib/mw-to-git/Makefile.

contrib/credential/netrc: work outside a repo

^{Signed-off-by: Denton Liu}

Currently, git-credential-netrc does not work outside of a git repository. It fails with the following error:

fatal: Not a git repository: . at /usr/share/perl5/Git.pm line 214.

There is no real reason why need to be within a repository, though. Credential helpers should be able to work just fine outside the repository as well.

Call the non-self version of config() so that git-credential-netrc no longer needs to be run within a repository.

Jeff King (peff) adds:

I assume you're using a gpg-encrypted netrc (if not, you should probably just use credential-store).
For "read-only" password access, I find the combination of pass with config like this is a bit nicer:

[credential "https://github.com"]
  username = peff
  helper = "!f() { test $1 = get && echo password=`pass github/oauth`; }; f"

You need to use HAVING, not WHERE.

The difference is: the WHERE clause filters which rows MySQL selects. Then MySQL groups the rows together and aggregates the numbers for your COUNT function.

HAVING is like WHERE, only it happens after the COUNT value has been computed, so it'll work as you expect. Rewrite your subquery as:

(                  -- where that pid is in the set:
SELECT c2.pid                  -- of pids
FROM Catalog AS c2             -- from catalog
WHERE c2.pid = c1.pid
HAVING COUNT(c2.sid) >= 2)

I tested and the script run ok!

<android.support.design.widget.FloatingActionButton   xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/somedrawable"
    android:layout_gravity="right|bottom"
    app:borderWidth="0dp"
    app:rippleColor="#ffffff"/>

app:borderWidth="0dp" is added as a workaround for elevation issues.

First of all, from __future__ import print_function needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print as a function now. That's the whole point of from __future__ import print_function; to bring the print function from Python 3 into Python 2.6+.

from __future__ import print_function

import sys, os, time

for x in range(0,10):
    print(x, sep=' ', end='')  # No need for sep here, but okay :)
    time.sleep(1)

__future__ statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:

A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.

The documentation also mentions that the only things that can precede a __future__ statement are the module docstring, comments, blank lines, and other future statements.

Actually, it is possible to provide the service (or guard, since that also needs to be provided) when creating the service.

The command is the following...

ng g s services/backendApi --module=app.module

Edit

It is possible to provide to a feature module, as well, you must give it the path to the module you would like.

ng g s services/backendApi --module=services/services.module

After the last Firefox update we had the same session timeout issue and the following setting helped to resolve it.

We can control it with network.http.response.timeout parameter.

1. Open Firefox and type in ‘about:config’ in the address bar and press Enter.
2. Click on the "I'll be careful, I promise!" button.
3. Type ‘timeout’ in the search box and network.http.response.timeout parameter will be displayed.
4. Double-click on the network.http.response.timeout parameter and enter the time value (it is in seconds) that you don't want your session not to timeout, in the box.

var optionTexts = [];
$("ul li").each(function() { optionTexts.push($(this).text()) });

...should do the trick. To get the final output you're looking for, join() plus some concatenation will do nicely:

var quotedCSV = '"' + optionTexts.join('", "') + '"';

It's called the protocol. The only thing that prevents you from making your own protocol is you have to:

1. Write a browser or user agent of some kinds that understands that protocol, both in its URL form and in the actual data format
2. Write a server that understands that protocol
3. Preferably, have a specification for the protocol so that browser and server can continue to work together.

Windows makes #1 really easy, an in many cases this is all you actually need. Viz:

Registering an Application to a URL Protocol

Variable definitions are meant to be used in tasks. But if you want to include them in tasks probably use the register directive. Like this:

- name: Define variable in task.
  shell: echo "http://www.my.url.com"
  register: url

- name: Download apache
  shell: wget {{ item }}
  with_items: url.stdout

You can also look at roles as a way of separating tasks depending on the different roles roles. This way you can have separate variables for each of one of your roles. For example you may have a url variable for apache1 and a separate url variable for the role apache2.

You can remove the spaces before casting to int:

(int)str_replace(' ', '', $b);

Also, if you want to strip other commonly used digit delimiters (such as ,), you can give the function an array (beware though -- in some countries, like mine for example, the comma is used for fraction notation):

(int)str_replace(array(' ', ','), '', $b);

Pattern module in not available from django 1.8. So you need to remove pattern from your import and do something similar to the following:

from django.conf.urls import include, url
from django.contrib import admin

admin.autodiscover()

urlpatterns = [                 
    # here we are not using pattern module like in previous django versions
    url(r'^admin/', include(admin.site.urls)),
]

In the top level of the IIS Manager (above Sites), you should see the Application Pools tree node. Right click on "Application Pools", choose "Add Application Pool".

Give it a name, choose .NET Framework 4.0 and either Integrated or Classic mode.

When you add or edit a web site, your new application pools will now show up in the list.

Since MySQL 5.6.X you can do this:

ALTER TABLE `schema`.`users` 
CHANGE COLUMN `created` `created` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP ;

That way your column will be updated with the current timestamp when a new row is inserted, or updated.

If you're using MySQL Workbench, you can just put CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP in the DEFAULT value field, like so:

http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-5.html

In case the target page is on the same domain (i.e. shares the same origin with your page) and you don't mind creation of new tabs (1), you can (ab)use some JavaScript:

<a href="javascript:void(window.open('./target.html').onload=function(){this.document.querySelector('p:nth-child(10)').scrollIntoView()})">see tenth paragraph on another page</a>

Trivia:

var w = window.open('some URL of the same origin');
w.onload = function(){
  // do whatever you want with `this.document`, like
  this.document.querySelecotor('footer').scrollIntoView()
}

Working example of such 'exploit' you can try right now could be:

javascript:(function(url,sel,w,el){w=window.open(url);w.addEventListener('load',function(){w.setTimeout(function(){el=w.document.querySelector(sel);el.scrollIntoView();el.style.backgroundColor='red'},1000)})})('https://stackoverflow.com/questions/45014240/link-to-a-specific-spot-on-a-page-i-cant-edit','footer')

If you enter this into location bar (mind that Chrome removes javascript: prefix when pasted from clipboard) or make it a href value of any link on this page (using Developer Tools) and click it, you will get another (duplicate) SO question page scrolled to the footer and footer painted red. (Delay added as a workaround for ajax-loaded content pushing footer down after load.)

Notes

• Tested in current Chrome and Firefox, generally should work since it is based on defined standard behaviour.
• Cannot be illustrated in interactive snippet here at SO, because they are isolated from the page origin-wise.
• MDN: Window.open()
• (1) window.open(url,'_self') seems to be breaking the load event; basically makes the window.open behave like a normal a href="" click navigation; haven't researched more yet.

200 (cache) means Firefox is simply using the locally cached version. This is the fastest because no request to the Web server is made.

304 means Firefox is sending a "If-Modified-Since" conditional request to the Web server. If the file has not been updated since the date sent by the browser, the Web server returns a 304 response which essentially tells Firefox to use its cached version. It is not as fast as 200 (cache) because the request is still sent to the Web server, but the server doesn't have to send the contents of the file.

To your last question, I don't know why the two JavaScript files in the same directory are returning different results.

Using some function on arrays: If any item in the array has an index number from the beginning is not equals to index number from the end, then this item exists in the array more than once.

// vanilla js
function hasDuplicates(arr) {
    return arr.some( function(item) {
        return arr.indexOf(item) !== arr.lastIndexOf(item);
    });
}

Apache Commons Lang has a Range class for doing arbitrary ranges.

Range<Integer> test = Range.between(1, 3);
System.out.println(test.contains(2));
System.out.println(test.contains(4));

Guava Range has similar API.

If you are just wanting to check if a number fits into a long value or an int value, you could try using it through BigDecimal. There are methods for longValueExact and intValueExact that throw exceptions if the value is too big for those precisions.

Solved: The problem lies here:

I set POST via both _CUSTOMREQUEST and _POST and the _CUSTOMREQUEST persisted as POST while _POST switched to _HTTPGET. The Server assumed the header from _CUSTOMREQUEST to be the right one and came back with a 411.

curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, 'POST');

For all selects, invoke this function.

$('select').on('change', function()
{
    alert( this.value );
});

For only one select:

$('#select_id') 

you get the detail information from Apple Dateformatter Document.If you want to set the dateformat for your dateString, see this link , the detail dateformat you can get here for e.g , do like

let formatter = DateFormatter()
// initially set the format based on your datepicker date / server String
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"

let myString = formatter.string(from: Date()) // string purpose I add here 
// convert your string to date
let yourDate = formatter.date(from: myString)
//then again set the date format whhich type of output you need
formatter.dateFormat = "dd-MMM-yyyy"
// again convert your date to string
let myStringafd = formatter.string(from: yourDate!)

print(myStringafd)

you get the output as

I believe that the problem in the fact that Moq will check for equality. And, since XmlElement does not override Equals, it's implementation will check for reference equality.

Can't you use a custom object, so you can override equals?

This is an old post, but I was looking for answer to this same question,

Why not try something like:

scale_color_manual(values = c("foo" = "#999999", "bar" = "#E69F00"))

If you have categorical values, I don't see a reason why this should not work.

I would suggest the following approach:

import {Autobind} from 'es-decorators';

export class Form extends Component {

    @Autobind
    handleChange(e) {
        this.setState({[e.target.name]: e.target.value});
    }

    @Autobind
    add(e) {
        e.preventDefault();
        this.collection.add(this.state);
        this.refs.form.reset();
    }

    shouldComponentUpdate() {
        return false;
    }

    render() {
        return (
            <form onSubmit={this.add} ref="form">
                <input type="text" name="desination" onChange={this.handleChange}/>
                <input type="date" name="startDate" onChange={this.handleChange}/>
                <input type="date" name="endDate" onChange={this.handleChange}/>
                <textarea name="description" onChange={this.handleChange}/>
                <button type="submit">Add</button>
            </form>
        )
    }

}

I recently had to create a button that would download a json file of all values of a large form. I needed this to work with IE/Edge/Chrome. This is what I did:

function download(text, name, type)
    {
        var file = new Blob([text], {type: type});
        var isIE = /*@cc_on!@*/false || !!document.documentMode;
        if (isIE)
        {
            window.navigator.msSaveOrOpenBlob(file, name);
        }
        else
        {
            var a = document.createElement('a');
            a.href = URL.createObjectURL(file);
            a.download = name;
            a.click();
        }
     }

download(jsonData, 'Form_Data_.json','application/json');

There was one issue with filename and extension in edge but at the time of writing this seemed to be a bug with Edge that is due to be fixed.

Hope this helps someone

I had the same error for a different package. My problem was that a dependent project was referencing a different version. I changed them to be the same version and all was good.

Update April 2013: Don't do this. It wasn't a good idea in 2009 when I first answered the question and it really isn't a good idea now. See this answer by hackbod for reasons:

Avoid reloading activity with asynctask on orientation change in android

Add android:configChanges="keyboardHidden|orientation" to your AndroidManifest.xml. This tells the system what configuration changes you are going to handle yourself - in this case by doing nothing.

<activity android:name="MainActivity"
     android:screenOrientation="portrait"
     android:configChanges="keyboardHidden|orientation">

See Developer reference configChanges for more details.

However, your application can be interrupted at any time, e.g. by a phone call, so you really should add code to save the state of your application when it is paused.

Update: As of Android 3.2, you also need to add "screenSize":

<activity
    android:name="MainActivity"
    android:screenOrientation="portrait"
    android:configChanges="keyboardHidden|orientation|screenSize">

From Developer guide Handling the Configuration Change Yourself

Caution: Beginning with Android 3.2 (API level 13), the "screen size" also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), you must include the "screenSize" value in addition to the "orientation" value. That is, you must declare android:configChanges="orientation|screenSize". However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device).

Samuel Liew is right. sometimes jquery conflict with the other jqueries. to solve this problem you need to put them in such a order that they may not conflict with each other. do one thing: open your application in google chrome and inspect bottom right corner with red marked errors. which kind of error that is?

I think that's another case of git error messages being misleading. Usually when I've seen that error it's due to ssh problems. Did you add your public ssh key to your github account?

Edit: Also, the xinet.d forum post is referring to running the git-daemon as a service so that people could pull from your system. It's not necessary to run git-daemon to push to github.

use this.animationStop, not use this.animationStop ( )

animationRun(){
    this.sliderClass.anim = true;
    setTimeout(this.animationStop, 500);
},

You can use the utility method in Collections class public static <T extends Comparable<? super T>> void sort(List<T> list) or

public static <T> void sort(List<T> list,Comparator<? super T> c)

Refer to Comparable and Comparator interfaces for more flexibility on sorting the object.

if you getting this type of error so I suggest you used to stored proc data as usual list then binding the other controls because I also get this error so I solved it like this ex:-

repeater.DataSource = data.SPBinsReport().Tolist();
repeater.DataBind();

try like this

Normally you should use __cplusplus define to detect c++17, but by default microsoft compiler does not define that macro properly, see https://devblogs.microsoft.com/cppblog/msvc-now-correctly-reports-__cplusplus/ - you need to either modify project settings to include /Zc:__cplusplus switch, or you could use syntax like this:

#if ((defined(_MSVC_LANG) && _MSVC_LANG >= 201703L) || __cplusplus >= 201703L)
     //C++17 specific stuff here
#endif

android:editable="false" should work, but it is deprecated, you should be using android:inputType="none" instead.

Alternatively, if you want to do it in the code you could do this :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setEnabled(false);

This is also a viable alternative :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setKeyListener(null);

If you're going to make your EditText non-editable, may I suggest using the TextView widget instead of the EditText, since using a EditText seems kind of pointless in that case.

EDIT: Altered some information since I've found that android:editable is deprecated, and you should use android:inputType="none", but there is a bug about it on android code; So please check this.

Edit as of 30.12.2015 - The Ultimate Guide to image downloading

last major update: Mar 31 2016

TL;DR a.k.a. stop talking, just give me the code!!

Skip to the bottom of this post, copy the BasicImageDownloader (javadoc version here) into your project, implement the OnImageLoaderListener interface and you're done.

Note: though the BasicImageDownloader handles possible errors and will prevent your app from crashing in case anything goes wrong, it will not perform any post-processing (e.g. downsizing) on the downloaded Bitmaps.

Since this post has received quite a lot of attention, I have decided to completely rework it to prevent the folks from using deprecated technologies, bad programming practices or just doing silly things - like looking for "hacks" to run network on the main thread or accept all SSL certs.

I've created a demo project named "Image Downloader" that demonstrates how to download (and save) an image using my own downloader implementation, the Android's built-in DownloadManager as well as some popular open-source libraries. You can view the complete source code or download the project on GitHub.

Note: I have not adjusted the permission management for SDK 23+ (Marshmallow) yet, thus the project is targeting SDK 22 (Lollipop).

In my conclusion at the end of this post I will share my humble opinion about the proper use-case for each particular way of image downloading I've mentioned.

Let's start with an own implementation (you can find the code at the end of the post). First of all, this is a BasicImageDownloader and that's it. All it does is connecting to the given url, reading the data and trying to decode it as a Bitmap, triggering the OnImageLoaderListener interface callbacks when appropriate. The advantage of this approach - it is simple and you have a clear overview of what's going on. A good way to go if all you need is downloading/displaying and saving some images, whilst you don't care about maintaining a memory/disk cache.

Note: in case of large images, you might need to scale them down.

--

Android DownloadManager is a way to let the system handle the download for you. It's actually capable of downloading any kind of files, not just images. You may let your download happen silently and invisible to the user, or you can enable the user to see the download in the notification area. You can also register a BroadcastReceiver to get notified after you download is complete. The setup is pretty much straightforward, refer to the linked project for sample code.

Using the DownloadManager is generally not a good idea if you also want to display the image, since you'd need to read and decode the saved file instead of just setting the downloaded Bitmap into an ImageView. The DownloadManager also does not provide any API for you app to track the download progress.

--

Now the introduction of the great stuff - the libraries. They can do much more than just downloading and displaying images, including: creating and managing the memory/disk cache, resizing images, transforming them and more.

I will start with Volley, a powerful library created by Google and covered by the official documentation. While being a general-purpose networking library not specializing on images, Volley features quite a powerful API for managing images.

You will need to implement a Singleton class for managing Volley requests and you are good to go.

You might want to replace your ImageView with Volley's NetworkImageView, so the download basically becomes a one-liner:

((NetworkImageView) findViewById(R.id.myNIV)).setImageUrl(url, MySingleton.getInstance(this).getImageLoader());

If you need more control, this is what it looks like to create an ImageRequest with Volley:

     ImageRequest imgRequest = new ImageRequest(url, new Response.Listener<Bitmap>() {
             @Override
             public void onResponse(Bitmap response) {
                    //do stuff
                }
            }, 0, 0, ImageView.ScaleType.CENTER_CROP, Bitmap.Config.ARGB_8888, 
             new Response.ErrorListener() {
             @Override
             public void onErrorResponse(VolleyError error) {
                   //do stuff
                }
            });

It is worth mentioning that Volley features an excellent error handling mechanism by providing the VolleyError class that helps you to determine the exact cause of an error. If your app does a lot of networking and managing images isn't its main purpose, then Volley it a perfect fit for you.

Square's Picasso is a well-known library which will do all of the image loading stuff for you. Just displaying an image using Picasso is as simple as:

 Picasso.with(myContext)
       .load(url)
       .into(myImageView); 

By default, Picasso manages the disk/memory cache so you don't need to worry about that. For more control you can implement the Target interface and use it to load your image into - this will provide callbacks similar to the Volley example. Check the demo project for examples.

Picasso also lets you apply transformations to the downloaded image and there are even other libraries around that extend those API. Also works very well in a RecyclerView/ListView/GridView.

--

Universal Image Loader is an another very popular library serving the purpose of image management. It uses its own ImageLoader that (once initialized) has a global instance which can be used to download images in a single line of code:

  ImageLoader.getInstance().displayImage(url, myImageView);

If you want to track the download progress or access the downloaded Bitmap:

 ImageLoader.getInstance().displayImage(url, myImageView, opts, 
 new ImageLoadingListener() {
     @Override
     public void onLoadingStarted(String imageUri, View view) {
                     //do stuff
                }

      @Override
      public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
                   //do stuff
                }

      @Override
      public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
                   //do stuff
                }

      @Override
      public void onLoadingCancelled(String imageUri, View view) {
                   //do stuff
                }
            }, new ImageLoadingProgressListener() {
      @Override
      public void onProgressUpdate(String imageUri, View view, int current, int total) {
                   //do stuff
                }
            });

The opts argument in this example is a DisplayImageOptions object. Refer to the demo project to learn more.

Similar to Volley, UIL provides the FailReason class that enables you to check what went wrong on download failure. By default, UIL maintains a memory/disk cache if you don't explicitly tell it not to do so.

Note: the author has mentioned that he is no longer maintaining the project as of Nov 27th, 2015. But since there are many contributors, we can hope that the Universal Image Loader will live on.

--

Facebook's Fresco is the newest and (IMO) the most advanced library that takes image management to a new level: from keeping Bitmaps off the java heap (prior to Lollipop) to supporting animated formats and progressive JPEG streaming.

To learn more about ideas and techniques behind Fresco, refer to this post.

The basic usage is quite simple. Note that you'll need to call Fresco.initialize(Context); only once, preferable in the Application class. Initializing Fresco more than once may lead to unpredictable behavior and OOM errors.

Fresco uses Drawees to display images, you can think of them as of ImageViews:

    <com.facebook.drawee.view.SimpleDraweeView
    android:id="@+id/drawee"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    fresco:fadeDuration="500"
    fresco:actualImageScaleType="centerCrop"
    fresco:placeholderImage="@drawable/placeholder_grey"
    fresco:failureImage="@drawable/error_orange"
    fresco:placeholderImageScaleType="fitCenter"
    fresco:failureImageScaleType="centerInside"
    fresco:retryImageScaleType="centerCrop"
    fresco:progressBarImageScaleType="centerInside"
    fresco:progressBarAutoRotateInterval="1000"
    fresco:roundAsCircle="false" />

As you can see, a lot of stuff (including transformation options) gets already defined in XML, so all you need to do to display an image is a one-liner:

 mDrawee.setImageURI(Uri.parse(url));

Fresco provides an extended customization API, which, under circumstances, can be quite complex and requires the user to read the docs carefully (yes, sometimes you need to RTFM).

I have included examples for progressive JPEG's and animated images into the sample project.

Conclusion - "I have learned about the great stuff, what should I use now?"

Note that the following text reflects my personal opinion and should not be taken as a postulate.

• If you only need to download/save/display some images, don't plan to use them in a Recycler-/Grid-/ListView and don't need a whole bunch of images to be display-ready, the BasicImageDownloader should fit your needs.
• If your app saves images (or other files) as a result of a user or an automated action and you don't need the images to be displayed often, use the Android DownloadManager.
• In case your app does a lot of networking, transmits/receives JSON data, works with images, but those are not the main purpose of the app, go with Volley.
• Your app is image/media-focused, you'd like to apply some transformations to images and don't want to bother with complex API: use Picasso (Note: does not provide any API to track the intermediate download status) or Universal Image Loader
• If your app is all about images, you need advanced features like displaying animated formats and you are ready to read the docs, go with Fresco.

You can also use head and tail:

In [29]: pd.concat([df.head(1), df.tail(1)])
Out[29]:
   a  b
0  1  a
3  4  d

This worked perfectly for me

objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

<img src="w3schools.jpg" alt="W3Schools.com" width="104" height="142">

In above html tag we have different attributes like src, alt, width and height.

If you want to get the any attribute value from above html tag you have to pass attribute value in getAttribute() method

Syntax:

getAttribute(attributeValue)
getAttribute(src) you get w3schools.jpg
getAttribute(height) you get 142
getAttribute(width) you get 104 

Trying with a different version of gcc worked for me - gcc 4.9 in my case.

I'm using fixed width string-parts (padded with whitespace) to avoid having the formatter mess up my SQL string indentation. This gives you mixed results, and won't work where whitespace is not ignored as it is in SQL, but can be helpful.

    final String sql = "SELECT v.value FROM properties p               "
            + "JOIN property_values v ON p.property_id = v.property_id "
            + "WHERE p.product_id = ?                                  "
            + "AND v.value        IS NOT NULL                          ";

public class DogAgeComparator implements Comparator<Dog> {
    public int compare(Dog o1, Dog o2) {
        return Integer.compare(o1.getAge(), o2.getId());
    }
}

Instead of modifying the height and width attributes of the image, try modifying the CSS height and width.

myimg = document.getElementById('myimg');
myimg.style.height = "50px";
myimg.style.width = "50px";

One common "gotcha" is that the height and width styles are strings that include a unit, like "px" in the example above.

Edit - I think that setting the height and width directly instead of using style.height and style.width should work. It would also have the advantage of already having the original dimensions. Can you post a bit of your code? Are you sure you're in standards mode instead of quirks mode?

This should work:

myimg = document.getElementById('myimg');
myimg.height = myimg.height * 2;
myimg.width = myimg.width * 2;

You need to make sure that no other users of this repository are fetching the incorrect changes or trying to build on top of the commits that you want removed because you are about to rewind history.

Then you need to 'force' push the old reference.

git push -f origin last_known_good_commit:branch_name

or in your case

git push -f origin cc4b63bebb6:alpha-0.3.0

You may have receive.denyNonFastForwards set on the remote repository. If this is the case, then you will get an error which includes the phrase [remote rejected].

In this scenario, you will have to delete and recreate the branch.

git push origin :alpha-0.3.0
git push origin cc4b63bebb6:refs/heads/alpha-0.3.0

If this doesn't work - perhaps because you have receive.denyDeletes set, then you have to have direct access to the repository. In the remote repository, you then have to do something like the following plumbing command.

git update-ref refs/heads/alpha-0.3.0 cc4b63bebb6 83c9191dea8

Note, while the modern form of updating submodule commits would be:

git submodule update --recursive --remote --merge --force

The older form was:

git submodule foreach --quiet git pull --quiet origin

Except... this second form is not really "quiet".

See commit a282f5a (12 Apr 2019) by Nguy?n Thái Ng?c Duy (pclouds).
^{(Merged by Junio C Hamano -- gitster -- in commit f1c9f6c, 25 Apr 2019)}

submodule foreach: fix "<command> --quiet" not being respected

Robin reported that

git submodule foreach --quiet git pull --quiet origin

is not really quiet anymore.
It should be quiet before fc1b924 (submodule: port submodule subcommand 'foreach' from shell to C, 2018-05-10, Git v2.19.0-rc0) because parseopt can't accidentally eat options then.

"git pull" behaves as if --quiet is not given.

This happens because parseopt in submodule--helper will try to parse both --quiet options as if they are foreach's options, not git-pull's.
The parsed options are removed from the command line. So when we do pull later, we execute just this

git pull origin

When calling submodule helper, adding "--" in front of "git pull" will stop parseopt for parsing options that do not really belong to submodule--helper foreach.

PARSE_OPT_KEEP_UNKNOWN is removed as a safety measure. parseopt should never see unknown options or something has gone wrong. There are also a couple usage string update while I'm looking at them.

While at it, I also add "--" to other subcommands that pass "$@" to submodule--helper. "$@" in these cases are paths and less likely to be --something-like-this.
But the point still stands, git-submodule has parsed and classified what are options, what are paths.
submodule--helper should never consider paths passed by git-submodule to be options even if they look like one.

And Git 2.23 (Q3 2019) fixes another issue: "git submodule foreach" did not protect command line options passed to the command to be run in each submodule correctly, when the "--recursive" option was in use.

See commit 30db18b (24 Jun 2019) by Morian Sonnet (momoson).
^{(Merged by Junio C Hamano -- gitster -- in commit 968eecb, 09 Jul 2019)}

submodule foreach: fix recursion of options

Calling:

git submodule foreach --recursive <subcommand> --<option>

leads to an error stating that the option --<option> is unknown to submodule--helper.
That is of course only, when <option> is not a valid option for git submodule foreach.

The reason for this is, that above call is internally translated into a call to submodule--helper:

git submodule--helper foreach --recursive \
   -- <subcommand> --<option>

This call starts by executing the subcommand with its option inside the first level submodule and continues by calling the next iteration of the submodule foreach call

git --super-prefix <submodulepath> submodule--helper \
  foreach --recursive <subcommand> --<option>

inside the first level submodule. Note that the double dash in front of the subcommand is missing.

This problem starts to arise only recently, as the PARSE_OPT_KEEP_UNKNOWN flag for the argument parsing of git submodule foreach was removed in commit a282f5a.
Hence, the unknown option is complained about now, as the argument parsing is not properly ended by the double dash.

This commit fixes the problem by adding the double dash in front of the subcommand during the recursion.

Note that, before Git 2.29 (Q4 2020), "git submodule update --quiet"^(man) did not squelch underlying "rebase" and "pull" commands.

See commit 3ad0401 (30 Sep 2020) by Theodore Dubois (tbodt).
^{(Merged by Junio C Hamano -- gitster -- in commit 300cd14, 05 Oct 2020)}

submodule update: silence underlying merge/rebase with "--quiet"

^{Signed-off-by: Theodore Dubois}

Commands such as

$ git pull --rebase --recurse-submodules --quiet  

produce non-quiet output from the merge or rebase.
Pass the --quiet option down when invoking "rebase" and "merge".

Also fix the parsing of git submodule update^(man) -v.

When e84c3cf3 ("git-submodule.sh: accept verbose flag in cmd_update to be non-quiet", 2018-08-14, Git v2.19.0-rc0 -- merge) taught "git submodule update"^(man) to take "--quiet", it apparently did not know how ${GIT_QUIET:+--quiet} works, and reviewers seem to have missed that setting the variable to "0", rather than unsetting it, still results in "--quiet" being passed to underlying commands.

you could use this formular to do the job -> get the CellValue for the specific row by typing: = indirect("$A&Cell()) depending on which column you have to check, you have to change the $A

For Example -> You could use a customized VBA Function in the Background:

Public Function IstDatum(Zelle) As Boolean IstDatum = False If IsDate(Zelle) Then IstDatum = True End Function

I need it to check for a date-entry in column A:

=IstDatum(INDIREKT("$A"&ZEILE()))

have a look at the picture:

I would like to add which isn't mentioned in above answers.

From your kibana's dev console, hit following command:

GET /

This is similar to accessing localhost:9200 from browser.

Hope this will help someone.

you can just set the selectedBackgroundView of the cell to be backgroundColor=x.

Now any time you tap on cell his selected mode will change automatically and will couse to the background color to change to x.

As others have said, the only correct answer is no, the type has been erased.

If the list has a non-zero number of elements, you could investigate the type of the first element ( using it's getClass method, for instance ). That won't tell you the generic type of the list, but it would be reasonable to assume that the generic type was some superclass of the types in the list.

I wouldn't advocate the approach, but in a bind it might be useful.

The 500 code would normally indicate an error on the server, not anything with your code. Some thoughts

• Talk to the server developer for more info. You can't get more info directly.
• Verify your arguments into the call (values). Look for anything you might think could cause a problem for the server process. The process should not die and should return you a better code, but bugs happen there also.
• Could be intermittent, like if the server database goes down. May be worth trying at another time.

try this, I am sure this will work for you.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type='text/javascript'>
    $(function() {

        try{
            opera.setOverrideHistoryNavigationMode('compatible');
            history.navigationMode = 'compatible';
        }catch(e){}

        function ReturnMessage()
        {
            return "wait";
        }

        function UnBindWindow()
        {
            $(window).unbind('beforeunload', ReturnMessage);
        }

        $(window).bind('beforeunload',ReturnMessage );
    });

You can use this simple code snippet using jQuery to redirect from a drop down menu.

<select id="dynamic-select">
    <option value="" selected>Pick a Website</option>
    <option value="http://www.google.com/">Google</option>
    <option value="http://www.youtube.com/">YouTube</option>
    <option value="http://www.stackoverflow.com/">Stack Overflow</option>
</select>

<script>
    $('#dynamic-select').bind('change', function () { // bind change event to select
        var url = $(this).val(); // get selected value
        if (url != '') { // require a URL
            window.location = url; // redirect
        }
        return false;
    });
</script>

If you use Spring Boot, you can configure Jackson globally as follows:

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;

@Configuration
public class JacksonObjectMapperConfiguration implements Jackson2ObjectMapperBuilderCustomizer {

    @Override
    public void customize(Jackson2ObjectMapperBuilder jacksonObjectMapperBuilder) {
        jacksonObjectMapperBuilder.visibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.NONE);
        jacksonObjectMapperBuilder.visibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);
        jacksonObjectMapperBuilder.visibility(PropertyAccessor.CREATOR, JsonAutoDetect.Visibility.ANY);
    }

}

Are you re-running your checkout or export into an existing directory?

Because if you are, checkout will update the working copy, including deleting any files.

But export will simply transfer all the files from the reporsitory to the destination - if the destination is the same directory, this means any files deleted in the repository will NOT be deleted.

So you export copy may only work because it is relying on a file which has been deleted in the repository?

I think the XML format can be so diverse that it's impossible to write a code that could do this without a very strict defined XML format. Here is what I mean:

<persons>
    <person>
        <name>Koen Bok</name>
        <age>26</age>
    </person>
    <person>
        <name>Plutor Heidepeen</name>
        <age>33</age>
    </person>
</persons>

Would become

{'persons': [
    {'name': 'Koen Bok', 'age': 26},
    {'name': 'Plutor Heidepeen', 'age': 33}]
}

But what would this be:

<persons>
    <person name="Koen Bok">
        <locations name="defaults">
            <location long=123 lat=384 />
        </locations>
    </person>
</persons>

See what I mean?

Edit: just found this article: http://www.xml.com/pub/a/2006/05/31/converting-between-xml-and-json.html

A const object is always static.

Since Guava 15.0 (released September 2013) there's EvictingQueue:

A non-blocking queue which automatically evicts elements from the head of the queue when attempting to add new elements onto the queue and it is full. An evicting queue must be configured with a maximum size. Each time an element is added to a full queue, the queue automatically removes its head element. This is different from conventional bounded queues, which either block or reject new elements when full.

This class is not thread-safe, and does not accept null elements.

Example use:

EvictingQueue<String> queue = EvictingQueue.create(2);
queue.add("a");
queue.add("b");
queue.add("c");
queue.add("d");
System.out.print(queue); //outputs [c, d]

Here's my solution, completely different to any else on here. It uses the mouse position to figure out if an option was clicked as oppose to clicking on the select box to open the dropdown. It makes use of the event.screenY position as this is the only reliable cross browser variable. A hover event has to be attached first so it can figure out the controls position relative to the screen before the click event.

var select = $("select");

var screenDif = 0;
select.bind("hover", function (e) {
    screenDif = e.screenY - e.clientY;
});
select.bind("click", function (e) {
    var element = $(e.target);
    var eventHorizon = screenDif + element.offset().top + element.height() - $(window).scrollTop();
    if (e.screenY > eventHorizon)
        alert("option clicked");
});

Here is my jsFiddle http://jsfiddle.net/sU7EV/4/

First, you're missing some parentheses in your conditional:

if ($("#about").hasClass("opened")) {
  $("#about").animate({right: "-700px"}, 2000);
}

But you can also simplify this to:

$('#about.opened').animate(...);

If #about doesn't have the opened class, it won't animate.

If the problem is with the animation itself, we'd need to know more about your element positioning (absolute? absolute inside relative parent? does the parent have layout?)

The break keyword does exactly that. Here is a contrived example:

public static void main(String[] args) {
  int i = 0;
  while (i++ < 10) {
    if (i == 5) break;
  }
  System.out.println(i); //prints 5
}

If you were actually using nested loops, you would be able to use labels.

When the LinkButton Enabled property is false it just renders a standard hyperlink. When you right click any disabled hyperlink you don't get the option to open in anything.

try

lbnkVidTtile1.Enabled = true;

I'm sorry if I misunderstood. Could I just make sure that you understand the purpose of a LinkButton? It is to give the appearance of a HyperLink but the behaviour of a Button. This means that it will have an anchor tag, but there is JavaScript wired up that performs a PostBack to the page. If you want to link to another page then it is recommended here that you use a standard HyperLink control.

If you are getting a timeout while on the table designer, change the "Transaction time-out after" value under Tools --> Options --> Designers --> Table and Database Designers

This will get rid of this message: "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."

I was able to figure it out. In case someone wants to know below the code that worked for me:

ASCIIEncoding ascii = new ASCIIEncoding();
byte[] byteArray = Encoding.UTF8.GetBytes(sOriginal);
byte[] asciiArray = Encoding.Convert(Encoding.UTF8, Encoding.ASCII, byteArray);
string finalString = ascii.GetString(asciiArray);

Let me know if there is a simpler way o doing it.

Here's an example using underscore functions.

var exampleArray = [{name: 'moe', age: 40}, {name: 'larry', age: 50}, {name: 'curly', age: 60}];
var finalArray = _.compact(_.pluck(exampleArray,"name")).join(",");

Final output would be "moe,larry,curly"

Improving the @Derek Springer post with fill length function:

public static String getFileWithDate(String fileName, String fileSaperator, String dateFormat) {
    String FileNamePrefix = fileName.substring(0, fileName.lastIndexOf(fileSaperator));
    String FileNameSuffix = fileName.substring(fileName.lastIndexOf(fileSaperator)+1, fileName.length());
    //System.out.println("File= Prefix~Suffix:"+FileNamePrefix +"~"+FileNameSuffix);
    
    String newFileName = new SimpleDateFormat("'"+FileNamePrefix+"_'"+dateFormat+"'"+fileSaperator+FileNameSuffix+"'").format(new Date());
    System.out.println("New File:"+newFileName);
    return newFileName;
}

Using the funciton and its Output:

String fileSaperator = ".", format = "yyyyMMMdd_HHmm";
getFileWithDate("Text1.txt", fileSaperator, format);
getFileWithDate("Text1.doc", fileSaperator, format);
getFileWithDate("Text1.txt.json", fileSaperator, format);

Output:

Old File:Text1.txt   New File:Text1_2020Nov11_1807.txt
Old File:Text1.doc   New File:Text1_2020Nov11_1807.doc
Old File:Text1.txt.json  New File:Text1.txt_2020Nov11_1807.json

As of Flutter v1.7.8+hotfix.2, the way to go is:

FocusScope.of(context).unfocus()

Comment on PR about that:

Now that #31909 (be75fb3) has landed, you should use FocusScope.of(context).unfocus() instead of FocusScope.of(context).requestFocus(FocusNode()), since FocusNodes are ChangeNotifiers, and should be disposed properly.

In operating systems ... one may use a linked list to keep track of what processes are running and what processes are sleeping ... a process that is running and wants to sleep ... gets removed from the LinkedList that keeps track of running processes and once the sleep time is over adds it back to the active process LinkedList

Maybe newer OS are using some funky data structures ... linked lists can be used there

CSS Media Queries & Logical Operators: A Brief Overview ;)

The quick answer.

Separate rules with commas: @media handheld, (min-width: 650px), (orientation: landscape) { ... }

The long answer.

There's a lot here, but I've tried to make it information dense, not just fluffy writing. It's been a good chance to learn myself! Take the time to systematically read though and I hope it will be helpful.

Media Queries

Media queries essentially are used in web design to create device- or situation-specific browsing experiences; this is done using the @media declaration within a page's CSS. This can be used to display a webpage differently under a large number of circumstances: whether you are on a tablet or TV with different aspect ratios, whether your device has a color or black-and-white screen, or, perhaps most frequently, when a user changes the size of their browser or switches between browsing devices with varying screen sizes (very generally speaking, designing like this is referred to as Responsive Web Design)

Logical Operators

In designing for these situations, there appear to be four Logical Operators that can be used to require more complex combinations of requirements when targeting a variety of devices or viewport sizes.

(Note: If you don't understand the the differences between media rules, media queries, and feature queries, browse the bottom section of this answer first to get a bit better acquainted with the terminology associated with media query syntax

1. AND (and keyword)

Requires that all conditions specified must be met before the styling rules will take effect.

@media screen and (min-width: 700px) and (orientation: landscape) { ... }

The specified styling rules won't go into place unless all of the following evaluate as true:

• The media type is 'screen' and
• The viewport is at least 700px wide and
• Screen orientation is currently landscape.

Note: I believe that used together, these three feature queries make up a single media query.

2. OR (Comma-separated lists)

Rather than an or keyword, comma-separated lists are used in chaining multiple media queries together to form a more complex media rule

@media handheld, (min-width: 650px), (orientation: landscape) { ... }

The specified styling rules will go into effect once any one media query evaluates as true:

1. The media type is 'handheld' or
2. The viewport is at least 650px wide or
3. Screen orientation is currently landscape.

3. NOT (not keyword)

The not keyword can be used to negate a single media query (and NOT a full media rule--meaning that it only negates entries between a set of commas and not the full media rule following the @media declaration).

Similarly, note that the not keyword negates media queries, it cannot be used to negate an individual feature query within a media query.*

@media not screen and (min-resolution: 300dpi), (min-width: 800px) { ... }

The styling specified here will go into effect if

1. The media type AND min-resolution don't both meet their requirements ('screen' and '300dpi' respectively) or
2. The viewport is at least 800 pixels wide.

In other words, if the media type is 'screen' and the min-resolution is 300 dpi, the rule will not go into effect unless the min-width of the viewport is at least 800 pixels.

(The not keyword can be a little funky to state. Let me know if I can do better. ;)

4. ONLY (only keyword)

As I understand it, the only keyword is used to prevent older browsers from misinterpreting newer media queries as the earlier-used, narrower media type. When used correctly, older/non-compliant browsers should just ignore the styling altogether.

<link rel="stylesheet" media="only screen and (color)" href="example.css" />

An older / non-compliant browser would just ignore this line of code altogether, I believe as it would read the only keyword and consider it an incorrect media type. (See here and here for more info from smarter people)

FOR MORE INFO

For more info (including more features that can be queried), see: https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Media_queries#Logical_operators

Understanding Media Query Terminology

Note: I needed to learn the following terminology for everything here to make sense, particularly concerning the not keyword. Here it is as I understand it:

A media rule (MDN also seems to call these media statements) includes the term @media with all of its ensuing media queries

@media all and (min-width: 800px)

@media only screen and (max-resolution:800dpi), not print

@media screen and (min-width: 700px), (orientation: landscape)

@media handheld, (min-width: 650px), (min-aspect-ratio: 1/1)

A media query is a set of feature queries. They can be as simple as one feature query or they can use the and keyword to form a more complex query. Media queries can be comma-separated to form more complex media rules (see the or keyword above).

screen (Note: Only one feature query in use here.)

only screen

only screen and (max-resolution:800dpi)

only tv and (device-aspect-ratio: 16/9) and (color)

NOT handheld, (min-width: 650px). (Note the comma: there are two media queries here.)

A feature query is the most basic portion of a media rule and simply concerns a given feature and its status in a given browsing situation.

screen

(min-width: 650px)

(orientation: landscape)

(device-aspect-ratio: 16/9)

If you want to remove all the data from all your tables, you might want to try the command python manage.py flush. This will delete all of the data in your tables, but the tables themselves will still exist.

It's used in case of a class method. Check this reference for further details.

EDIT: As clarified by Adrien, it's a convention. You can actually use anything but cls and self are used (PEP8).

Not as bulletproof as the above answer, however still effective:

#!/bin/bash
if [ "$1" = "" ]
then
  echo "Usage: $0 <id number to be cleaned up>"
  exit

# rm commands go here

I have the same problem. I avoid it with remove.packages("Package making this confusion") and it works. In my case, I don't need the second package, so that is not a very good idea.

I know this question is a little old but the following worked for me in a Jupyter Notebook running pandas 0.22.0 and Python 3:

import pandas as pd
pd.set_option('display.max_columns', <number of columns>)

You can do the same for the rows too:

pd.set_option('display.max_rows', <number of rows>)

This saves importing IPython, and there are more options in the pandas.set_option documentation: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.set_option.html

I believe you're looking for...

import config.logging_settings  # @UnusedImport

Note the double space before the comment to avoid hitting other formatting warnings.

Also, depending on your IDE (if you're using one), there's probably an option to add the correct ignore rule (e.g., in Eclipse, pressing Ctrl + 1, while the cursor is over the warning, will auto-suggest @UnusedImport).

Try this code:

var myXmlDocument = new XmlDocument();
myXmlDocument.LoadXml(theString);

Swift 3 version

extension UIView {
    enum ViewSide {
        case Top, Bottom, Left, Right
    }

    func addBorder(toSide side: ViewSide, withColor color: UIColor, andThickness thickness: CGFloat) {

        let border = CALayer()
        border.backgroundColor = color.cgColor

        switch side {
        case .Top:
            border.frame = CGRect(x: 0, y: 0, width: frame.size.width, height: thickness)
        case .Bottom:
            border.frame = CGRect(x: 0, y: frame.size.height - thickness, width: frame.size.width, height: thickness)
        case .Left:
            border.frame = CGRect(x: 0, y: 0, width: thickness, height: frame.size.height)
        case .Right:
            border.frame = CGRect(x: frame.size.width - thickness, y: 0, width: thickness, height: frame.size.height)
        }

        layer.addSublayer(border)
    }
}

In order to set corresponding border you should override viewDidLayoutSubviews() method:

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    yourView.addBorder(toSide: UIView.ViewSide.Top, withColor: UIColor.lightGray, andThickness: 1)

I had a similar problem. I had done a project using Visual Studio 2010 and then got the above error when i compiled it using Visual Studio 2012. I simple copied all the contents of C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A into C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A and that solved my problem.

A function to access the values:

def shape(tensor):
    s = tensor.get_shape()
    return tuple([s[i].value for i in range(0, len(s))])

Example:

batch_size, num_feats = shape(logits)

You can simulate them for example with hashes, but need care about the leading zeroes and many other things. The next demonstration works, but it is far from optimal solution.

#!/bin/bash
declare -A matrix
num_rows=4
num_columns=5

for ((i=1;i<=num_rows;i++)) do
    for ((j=1;j<=num_columns;j++)) do
        matrix[$i,$j]=$RANDOM
    done
done

f1="%$((${#num_rows}+1))s"
f2=" %9s"

printf "$f1" ''
for ((i=1;i<=num_rows;i++)) do
    printf "$f2" $i
done
echo

for ((j=1;j<=num_columns;j++)) do
    printf "$f1" $j
    for ((i=1;i<=num_rows;i++)) do
        printf "$f2" ${matrix[$i,$j]}
    done
    echo
done

the above example creates a 4x5 matrix with random numbers and print it transposed, with the example result

           1         2         3         4
 1     18006     31193     16110     23297
 2     26229     19869      1140     19837
 3      8192      2181     25512      2318
 4      3269     25516     18701      7977
 5     31775     17358      4468     30345

The principle is: Creating one associative array where the index is an string like 3,4. The benefits:

• it's possible to use for any-dimension arrays ;) like: 30,40,2 for 3 dimensional.
• the syntax is close to "C" like arrays ${matrix[2,3]}

Ensure that mobile devices won't change the font with their default font by using important along with the universal selector * :

All of the DISPATCH_QUEUE_PRIORITY_X queues are concurrent queues (meaning they can execute multiple tasks at once), and are FIFO in the sense that tasks within a given queue will begin executing using "first in, first out" order. This is in comparison to the main queue (from dispatch_get_main_queue()), which is a serial queue (tasks will begin executing and finish executing in the order in which they are received).

So, if you send 1000 dispatch_async() blocks to DISPATCH_QUEUE_PRIORITY_DEFAULT, those tasks will start executing in the order you sent them into the queue. Likewise for the HIGH, LOW, and BACKGROUND queues. Anything you send into any of these queues is executed in the background on alternate threads, away from your main application thread. Therefore, these queues are suitable for executing tasks such as background downloading, compression, computation, etc.

Note that the order of execution is FIFO on a per-queue basis. So if you send 1000 dispatch_async() tasks to the four different concurrent queues, evenly splitting them and sending them to BACKGROUND, LOW, DEFAULT and HIGH in order (ie you schedule the last 250 tasks on the HIGH queue), it's very likely that the first tasks you see starting will be on that HIGH queue as the system has taken your implication that those tasks need to get to the CPU as quickly as possible.

Note also that I say "will begin executing in order", but keep in mind that as concurrent queues things won't necessarily FINISH executing in order depending on length of time for each task.

As per Apple:

https://developer.apple.com/library/content/documentation/General/Conceptual/ConcurrencyProgrammingGuide/OperationQueues/OperationQueues.html

A concurrent dispatch queue is useful when you have multiple tasks that can run in parallel. A concurrent queue is still a queue in that it dequeues tasks in a first-in, first-out order; however, a concurrent queue may dequeue additional tasks before any previous tasks finish. The actual number of tasks executed by a concurrent queue at any given moment is variable and can change dynamically as conditions in your application change. Many factors affect the number of tasks executed by the concurrent queues, including the number of available cores, the amount of work being done by other processes, and the number and priority of tasks in other serial dispatch queues.

Basically, if you send those 1000 dispatch_async() blocks to a DEFAULT, HIGH, LOW, or BACKGROUND queue they will all start executing in the order you send them. However, shorter tasks may finish before longer ones. Reasons behind this are if there are available CPU cores or if the current queue tasks are performing computationally non-intensive work (thus making the system think it can dispatch additional tasks in parallel regardless of core count).

The level of concurrency is handled entirely by the system and is based on system load and other internally determined factors. This is the beauty of Grand Central Dispatch (the dispatch_async() system) - you just make your work units as code blocks, set a priority for them (based on the queue you choose) and let the system handle the rest.

So to answer your above question: you are partially correct. You are "asking that code" to perform concurrent tasks on a global concurrent queue at the specified priority level. The code in the block will execute in the background and any additional (similar) code will execute potentially in parallel depending on the system's assessment of available resources.

The "main" queue on the other hand (from dispatch_get_main_queue()) is a serial queue (not concurrent). Tasks sent to the main queue will always execute in order and will always finish in order. These tasks will also be executed on the UI Thread so it's suitable for updating your UI with progress messages, completion notifications, etc.

Whatever the name of your dump file, it's the content which does matter.

You need to check your mydatabase.sql and find this line :

USE mydatabasename;

This name does matter, and it's the one you must use in your command :

mysql -uroot -pmypassword mydatabasename<mydatabase.sql;

Two options for you :

1. Remove USE mydatabasename; in your dump, and keep using :
   mysql -uroot -pmypassword mydatabase<mydatabase.sql;
2. Change your local database name to fit the one in your SQL dump, and use :
   mysql -uroot -pmypassword mydatabasename<mydatabase.sql;

I was using private npm registry and trying to install private npm module. Logging to npm local registry fixed it (used command npm --add-user)

First make the URL format correct for getting the query string use #?q=string that works for me

http://localhost/codeschool/index.php#?foo=abcd

Inject $location service into the controller

app.controller('MyController', [ '$location', function($location) { 

    var searchObject = $location.search();

    // $location.search(); reutrn object 
    // searchObject = { foo = 'abcd' };

    alert( searchObject.foo );

} ]);

So the out put should be abcd

You cannot use Set Transaction Isolation Level Read Uncommitted in a View (you can only have one script in there in fact), so you would have to use (nolock) if dirty rows should be included.

empty is an operator:

The empty operator is a prefix operation that can be used to determine whether a value is null or empty.

<c:if test="${empty myObject.featuresList}">

If you know your file will live where your classes are, that directory will be on your classpath. In that case, you can be sure that this solution will solve your problem:

URL path = ClassLoader.getSystemResource("myFile.txt");
if(path==null) {
     //The file was not found, insert error handling here
}
File f = new File(path.toURI());

reader = new BufferedReader(new FileReader(f));

background: url(../images/backgroundImage.jpg) no-repeat center center fixed;

this should help

\n must be in double quotes!

 echo '<p>' . $unit1 . "</p>\n";

When using the for loop, the value of s is a Map.Entry element, meaning that you can get the key from s.key and the value from s.value

You could use pandas.to_datetime() as recommended in the documentation for pandas.read_csv():

If a column or index contains an unparseable date, the entire column or index will be returned unaltered as an object data type. For non-standard datetime parsing, use pd.to_datetime after pd.read_csv.

Demo:

>>> D = {'date': '2013-6-4'}
>>> df = pd.DataFrame(D, index=[0])
>>> df
       date
0  2013-6-4
>>> df.dtypes
date    object
dtype: object
>>> df['date'] = pd.to_datetime(df.date, format='%Y-%m-%d')
>>> df
        date
0 2013-06-04
>>> df.dtypes
date    datetime64[ns]
dtype: object

In this way we can pass an array to a function, here this print function will print the contents of the array.

public class PassArrayToFunc {

    public static void print(char [] arr) {
        for(int i = 0 ; i<arr.length;i++) {
            System.out.println(arr[i]);
        }
    }

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        char [] array = scan.next().toCharArray();
        print(array);
        scan.close();
    }

}

with paging you need to do some calculation

int index = Convert.ToInt32(e.CommandArgument) % GridView1.PageSize;

If you are using Apache 2.4 ,without the need to enable the rewrite apache module you can use something like this:

# non-www to www
<If "%{HTTP_HOST} = 'domain.com'">
  Redirect 301 "/" "http://www.domain.com/"
</If>

You're declaring everything in the parent page. So the references to window and document are to the parent page's. If you want to do stuff to the iframe's, use iframe || iframe.contentWindow to access its window, and iframe.contentDocument || iframe.contentWindow.document to access its document.

There's a word for what's happening, possibly "lexical scope": What is lexical scope?

The only context of a scope is this. And in your example, the owner of the method is doc, which is the iframe's document. Other than that, anything that's accessed in this function that uses known objects are the parent's (if not declared in the function). It would be a different story if the function were declared in a different place, but it's declared in the parent page.

This is how I would write it:

(function () {
  var dom, win, doc, where, iframe;

  iframe = document.createElement('iframe');
  iframe.src = "javascript:false";

  where = document.getElementsByTagName('script')[0];
  where.parentNode.insertBefore(iframe, where);

  win = iframe.contentWindow || iframe;
  doc = iframe.contentDocument || iframe.contentWindow.document;

  doc.open();
  doc._l = (function (w, d) {
    return function () {
      w.vanishing_global = new Date().getTime();

      var js = d.createElement("script");
      js.src = 'test-vanishing-global.js?' + w.vanishing_global;

      w.name = "foobar";
      d.foobar = "foobar:" + Math.random();
      d.foobar = "barfoo:" + Math.random();
      d.body.appendChild(js);
    };
  })(win, doc);
  doc.write('<body onload="document._l();"></body>');
  doc.close();
})();

The aliasing of win and doc as w and d aren't necessary, it just might make it less confusing because of the misunderstanding of scopes. This way, they are parameters and you have to reference them to access the iframe's stuff. If you want to access the parent's, you still use window and document.

I'm not sure what the implications are of adding methods to a document (doc in this case), but it might make more sense to set the _l method on win. That way, things can be run without a prefix...such as <body onload="_l();"></body>

Cookies are used to identify sessions. Visit any site that is using cookies and pull up either Chrome inspect element and then network or FireBug if using Firefox.

You can see that there is a header sent to a server and also received called Cookie. Usually it contains some personal information (like an ID) that can be used on the server to identify a session. These cookies stay on your computer and your browser takes care of sending them to only the domains that are identified with it.

If there were no cookies then you would be sending a unique ID on every request via GET or POST. Cookies are like static id's that stay on your computer for some time.

A session is a group of information on the server that is associated with the cookie information. If you're using PHP you can check the session.save_path location and actually "see sessions". They are either files on the server filesystem or backed in a database.

This is a simple, you can use spring boot maven plugin to finish your code deploy.

the plugin config like:

I would comment if i could , but i have no permissions yet, so i will post a hint as an answer, for unexpected behavior on some android devices:

Oh I found it in the PHP manual.

foreach ($array as $key => $value){
    statement
}

The current element's key will be assigned to the variable $key on each loop.

Following up as of 2019-04-04, this seems to be able to be accomplished with the React Hooks' useState:

import React, { useState } from 'react'
import uniqueId from 'lodash/utility/uniqueId'

const Field = props => {
  const [ id ] = useState(uniqueId('myprefix-'))

  return (
    <div>
      <label htmlFor={id}>{props.label}</label>
      <input id={id} type="text"/>
    </div>
  )      
}

export default Field

As I understand it, you ignore the second array item in the array destructuring that would allow you to update id, and now you've got a value that won't be updated again for the life of the component.

The value of id will be myprefix-<n> where <n> is an incremental integer value returned from uniqueId. If that's not unique enough for you, consider making your own like

function gen4() {
  return Math.random().toString(16).slice(-4)
}

function simpleUniqueId(prefix) {
  return (prefix || '').concat([
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4()
  ].join(''))
}

or check out the library I published with this here: https://github.com/rpearce/simple-uniqueid. There are also hundreds or thousands of other unique ID things out there, but lodash's uniqueId with a prefix should be enough to get the job done.

Update 2019-07-10

Thanks to @Huong Hk for pointing me to hooks lazy initial state, the sum of which is that you can pass a function to useState that will only be run on the initial mount.

// before
const [ id ] = useState(uniqueId('myprefix-'))

// after
const [ id ] = useState(() => uniqueId('myprefix-'))

If you are looking for an objective analysis of both the editors, look at their origins and the philosophy behind their respective designs. Think, which one would suit you better and learn it (and learn it and learn it, because it takes time before you being to discover its true utility as against any IDE). An Introduction to Display Editing with Vi was written by Bill Joy and Mark Horton and he explains why he choose modal design and rationale for various key strokes ( it helps me to remember that CTRL-W +W (will switch to next Window and it will same for CTRL W+ CTRL W, just in case you held the CTRL key for a longer duration.

Here is a link to Emacs timeline and has the reference to Multics Emacs paper. Hereis RMS paper on Emacs, where I see the stress is on a programmable text editor (even way back in 1981 and before).

I have not read the emacs papers, but have read Bill Joy's vi paper a couple of times. Both are old, but still you will get the philosophy and you might choose to use the current tool (vim 7.x or emacs 25?)

Edit: I forgot to mention that it takes patience and imagination to read both these papers as it takes you back in time while reading it. But it is worth.

Checkout the .SaveAs() method in Excel object.

wbWorkbook.SaveAs("c:\yourdesiredFilename.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlCSV)

Or following:

public static void SaveAs()
{
    Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.ApplicationClass();
    Microsoft.Office.Interop.Excel.Workbook wbWorkbook = app.Workbooks.Add(Type.Missing);
    Microsoft.Office.Interop.Excel.Sheets wsSheet = wbWorkbook.Worksheets;
    Microsoft.Office.Interop.Excel.Worksheet CurSheet = (Microsoft.Office.Interop.Excel.Worksheet)wsSheet[1];

    Microsoft.Office.Interop.Excel.Range thisCell = (Microsoft.Office.Interop.Excel.Range)CurSheet.Cells[1, 1];

    thisCell.Value2 = "This is a test.";

    wbWorkbook.SaveAs(@"c:\one.xls", Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
    wbWorkbook.SaveAs(@"c:\two.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlCSVWindows, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

    wbWorkbook.Close(false, "", true);
}

(array1 + array2).uniq

This way you get array1 elements first. You will get no duplicates.

Create a DataView. You cannot sort a DataTable directly, but you can create a DataView from the DataTable and sort that.

Creating: http://msdn.microsoft.com/en-us/library/hy5b8exc.aspx

Sorting: http://msdn.microsoft.com/en-us/library/13wb36xf.aspx

The following code example creates a view that shows all the products where the number of units in stock is less than or equal to the reorder level, sorted first by supplier ID and then by product name.

DataView prodView = new DataView(prodDS.Tables["Products"], "UnitsInStock <= ReorderLevel", "SupplierID, ProductName", DataViewRowState.CurrentRows);

In my case it was a lack of SSL support in PHP which gave this error.

Using the java.time package in Java 8:

Instant start = Instant.now();
Thread.sleep(63553);
Instant end = Instant.now();
System.out.println(Duration.between(start, end));

Output is in ISO 8601 Duration format: PT1M3.553S (1 minute and 3.553 seconds).

You can use Regular Expression for Sanitization. Inside filter before calling chain.doFilter(request, response) method, call this code. Here is Sample Code:

for (Enumeration en = request.getParameterNames(); en.hasMoreElements(); ) {
String name = (String)en.nextElement();
String values[] = request.getParameterValues(name);
int n = values.length;
    for(int i=0; i < n; i++) {
     values[i] = values[i].replaceAll("[^\\dA-Za-z ]","").replaceAll("\\s+","+").trim();   
    }
}

insert into tbl2
select field1,field2,... from tbl1

    ( 
        select field1,field2,... 
        from person2
        where (tbl1.field1=tbl2.field1 and
        tbl1.field2=tbl2.field2 and .....)
    )

You can use Named Sections.

_Layout.cshtml

I have not used bundle exec much, but am setting it up now.

I have had instances where the wrong rake was used and much time wasted tracking down the problem. This helps you avoid that.

Here's how to set up RVM so you can use bundle exec by default within a specific project directory:

The function you pass to stream.map has to return one object. That means each object in the input stream results in exactly one object in the output stream.

The function you pass to stream.flatMap returns a stream for each object. That means the function can return any number of objects for each input object (including none). The resulting streams are then concatenated to one output stream.

To get the id of the parent div:

$(buttonSelector).parents('div:eq(0)').attr('id');

Also, you can refactor your code quite a bit:

$('button').click( function() {
 var correct = Number($(this).attr('rel'));
 validate(Number($(this).siblings('input').val()), correct);
 $(this).parents('div:eq(0)').html(feedback);
});

Now there is no need for a button-class

explanation
eq(0), means that you will select one element from the jQuery object, in this case element 0, thus the first element. http://docs.jquery.com/Selectors/eq#index
$(selector).siblings(siblingsSelector) will select all siblings (elements with the same parent) that match the siblingsSelector http://docs.jquery.com/Traversing/siblings#expr
$(selector).parents(parentsSelector) will select all parents of the elements matched by selector that match the parent selector. http://docs.jquery.com/Traversing/parents#expr
Thus: $(selector).parents('div:eq(0)'); will match the first parent div of the elements matched by selector.

You should have a look at the jQuery docs, particularly selectors and traversing:

• http://docs.jquery.com/
• http://docs.jquery.com/Selectors
• http://docs.jquery.com/Traversing

IF this is only occurring on deployments, be sure that you have the dependency of the package you are referencing in the .war. For instance, this was working locally on my machine, with debug configurations working fine, but after deploying to Amazon's Elastic Beanstalk , I received this error and noticed one of the dependencies was not bundled in the .war package.

Doing this with POSIX is tricky:

• POSIX Sed does not support \r or \15. Even if it did, the in place option -i is not POSIX

• POSIX Awk does support \r and \15, however the -i inplace option is not POSIX

• d2u and dos2unix are not POSIX utilities, but ex is

• POSIX ex does not support \r, \15, \n or \12

To remove carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\r","");print>ARGV[1]}' file

To add carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\n","\r&");print>ARGV[1]}' file

Looks like this will be finally supported in the SQL Server 2019! SQL Server 2019 - whats new?

From BOL:

UTF-8 support

Full support for the widely used UTF-8 character encoding as an import or export encoding, or as database-level or column-level collation for text data. UTF-8 is allowed in the CHAR and VARCHAR datatypes, and is enabled when creating or changing an object’s collation to a collation with the UTF8 suffix.

For example,LATIN1_GENERAL_100_CI_AS_SC to LATIN1_GENERAL_100_CI_AS_SC_UTF8. UTF-8 is only available to Windows collations that support supplementary characters, as introduced in SQL Server 2012. NCHAR and NVARCHAR allow UTF-16 encoding only, and remain unchanged.

This feature may provide significant storage savings, depending on the character set in use. For example, changing an existing column data type with ASCII strings from NCHAR(10) to CHAR(10) using an UTF-8 enabled collation, translates into nearly 50% reduction in storage requirements. This reduction is because NCHAR(10) requires 22 bytes for storage, whereas CHAR(10) requires 12 bytes for the same Unicode string.

2019-05-14 update:

Documentation seems to be updated now and explains our options staring in MSSQL 2019 in section "Collation and Unicode Support".

Simple one without rank :

rum[order(rum$I1, -rum$I2, decreasing = TRUE), ]

The use of fork and exec exemplifies the spirit of UNIX in that it provides a very simple way to start new processes.

The fork call basically makes a duplicate of the current process, identical in almost every way. Not everything is copied over (for example, resource limits in some implementations) but the idea is to create as close a copy as possible.

The new process (child) gets a different process ID (PID) and has the PID of the old process (parent) as its parent PID (PPID). Because the two processes are now running exactly the same code, they can tell which is which by the return code of fork - the child gets 0, the parent gets the PID of the child. This is all, of course, assuming the fork call works - if not, no child is created and the parent gets an error code.

The exec call is a way to basically replace the entire current process with a new program. It loads the program into the current process space and runs it from the entry point.

So, fork and exec are often used in sequence to get a new program running as a child of a current process. Shells typically do this whenever you try to run a program like find - the shell forks, then the child loads the find program into memory, setting up all command line arguments, standard I/O and so forth.

But they're not required to be used together. It's perfectly acceptable for a program to fork itself without execing if, for example, the program contains both parent and child code (you need to be careful what you do, each implementation may have restrictions). This was used quite a lot (and still is) for daemons which simply listen on a TCP port and fork a copy of themselves to process a specific request while the parent goes back to listening.

Similarly, programs that know they're finished and just want to run another program don't need to fork, exec and then wait for the child. They can just load the child directly into their process space.

Some UNIX implementations have an optimized fork which uses what they call copy-on-write. This is a trick to delay the copying of the process space in fork until the program attempts to change something in that space. This is useful for those programs using only fork and not exec in that they don't have to copy an entire process space.

If the exec is called following fork (and this is what happens mostly), that causes a write to the process space and it is then copied for the child process.

Note that there is a whole family of exec calls (execl, execle, execve and so on) but exec in context here means any of them.

The following diagram illustrates the typical fork/exec operation where the bash shell is used to list a directory with the ls command:

+--------+
| pid=7  |
| ppid=4 |
| bash   |
+--------+
    |
    | calls fork
    V
+--------+             +--------+
| pid=7  |    forks    | pid=22 |
| ppid=4 | ----------> | ppid=7 |
| bash   |             | bash   |
+--------+             +--------+
    |                      |
    | waits for pid 22     | calls exec to run ls
    |                      V
    |                  +--------+
    |                  | pid=22 |
    |                  | ppid=7 |
    |                  | ls     |
    V                  +--------+
+--------+                 |
| pid=7  |                 | exits
| ppid=4 | <---------------+
| bash   |
+--------+
    |
    | continues

SET GLOBAL LOG_SLOW_TIME = 1;
SET GLOBAL LOG_QUERIES_NOT_USING_INDEXES = ON;

Broken on my setup 5.1.42

SET GLOBAL LOG_SLOW_QUERIES = ON;
SET GLOBAL SLOW_QUERY_LOG = ON;
set @@global.log_slow_queries=1;

http://bugs.mysql.com/bug.php?id=32565

Looks like the best way to do this is set log_slow_time very high thus "turning off" the slow query log. Lower log_slow_time to enable it. Use the same trick (set to OFF) for log_queries_not_using_indexes.

Another option is to use the TimeUtils utility method:

TimeUtils.millisToUnit(System.currentTimeMillis(), TimeUnit.SECONDS)

For those using Altap Salamander (2 panels file manager) : in the Options of the Copy popup, just specify the file names or masks. Easy.

Add inputType to edittext and on enter it will go the next edittext

android:inputType="text"
android:inputType="textEmailAddress"

and many more.

inputType=textMultiLine does not go to the next edittext on enter

Here's the solution you're looking for:

>>> foos = [1.0, 2.0, 3.0, 4.0, 5.0]
>>> bars = [1, 2, 3]
>>> [(x, bars) for x in foos]
[(1.0, [1, 2, 3]), (2.0, [1, 2, 3]), (3.0, [1, 2, 3]), (4.0, [1, 2, 3]), (5.0, [
1, 2, 3])]

I'd recommend using a list comprehension (the [(x, bars) for x in foos] part) over using map as it avoids the overhead of a function call on every iteration (which can be very significant). If you're just going to use it in a for loop, you'll get better speeds by using a generator comprehension:

>>> y = ((x, bars) for x in foos)
>>> for z in y:
...     print z
...
(1.0, [1, 2, 3])
(2.0, [1, 2, 3])
(3.0, [1, 2, 3])
(4.0, [1, 2, 3])
(5.0, [1, 2, 3])

The difference is that the generator comprehension is lazily loaded.

UPDATE In response to this comment:

Of course you know, that you don't copy bars, all entries are the same bars list. So if you modify any one of them (including original bars), you modify all of them.

I suppose this is a valid point. There are two solutions to this that I can think of. The most efficient is probably something like this:

tbars = tuple(bars)
[(x, tbars) for x in foos]

Since tuples are immutable, this will prevent bars from being modified through the results of this list comprehension (or generator comprehension if you go that route). If you really need to modify each and every one of the results, you can do this:

from copy import copy
[(x, copy(bars)) for x in foos]

However, this can be a bit expensive both in terms of memory usage and in speed, so I'd recommend against it unless you really need to add to each one of them.

I use this class:

public class JsonContent : StringContent
{
    public JsonContent(object obj) :
        base(JsonConvert.SerializeObject(obj), Encoding.UTF8, "application/json")
    { }
}

Sample of usage:

new HttpClient().PostAsync("http://...", new JsonContent(new { x = 1, y = 2 }));

for decreasing order for integer array of 2 dimension you can use

Arrays.sort(contests, (a, b) -> Integer.compare(b[0],a[0]));//decreasing order

Arrays.sort(contests, (a, b) -> Integer.compare(a[0],b[0]);//decreasing order

I prefer to fetch and checkout without creating a local branch and to be in HEAD detached state. It allows me quickly to check the pull request without polluting my local machine with unnecessary local branches.

git fetch upstream pull/ID/head && git checkout FETCH_HEAD

where ID is a pull request ID and upstream where is original pull request has been created (it could be origin, for example).

I hope it helps.

By latest document, you can use rdd.collect().foreach(println) on the driver to display all, but it may cause memory issues on the driver, best is to use rdd.take(desired_number)

https://spark.apache.org/docs/2.2.0/rdd-programming-guide.html

To print all elements on the driver, one can use the collect() method to first bring the RDD to the driver node thus: rdd.collect().foreach(println). This can cause the driver to run out of memory, though, because collect() fetches the entire RDD to a single machine; if you only need to print a few elements of the RDD, a safer approach is to use the take(): rdd.take(100).foreach(println).

Have a look at the Except method, which you use like this:

var resultingList = 
    listOfOriginalItems.Except(listOfItemsToLeaveOut, equalityComparer)

You'll want to use the overload I've linked to, which lets you specify a custom IEqualityComparer. That way you can specify how items match based on your composite key. (If you've already overridden Equals, though, you shouldn't need the IEqualityComparer.)

Edit: Since it appears you're using two different types of classes, here's another way that might be simpler. Assuming a List<Person> called persons and a List<Exclusion> called exclusions:

var exclusionKeys = 
        exclusions.Select(x => x.compositeKey);
var resultingPersons = 
        persons.Where(x => !exclusionKeys.Contains(x.compositeKey));

In other words: Select from exclusions just the keys, then pick from persons all the Person objects that don't have any of those keys.

You could skip all this and just put your data in a table. Then refer to the table and header and it will be completely dynamic. I know this is from 3 years ago but someone may still find this useful.

Example code:

Activesheet.Range("TableName[ColumnName]").Copy

You can also use :

activesheet.listobjects("TableName[ColumnName]").Copy

You can even use this reference system in worksheet formulas as well. Its very dynamic.

Hope this helps!

Also with dict

a = []
b = {1:'one'}

Use namespace

using System.Collections.Specialized;

Make instance of DataContext Class

LinqToSqlDataContext dc = new LinqToSqlDataContext();

Use

OrderedDictionary dict = dc.TableName.ToDictionary(d => d.key, d => d.value);

In order to retrieve the values use namespace

   using System.Collections;

ICollection keyCollections = dict.Keys;
ICOllection valueCollections = dict.Values;

String[] myKeys = new String[dict.Count];
String[] myValues = new String[dict.Count];

keyCollections.CopyTo(myKeys,0);
valueCollections.CopyTo(myValues,0);

for(int i=0; i<dict.Count; i++)
{
Console.WriteLine("Key: " + myKeys[i] + "Value: " + myValues[i]);
}
Console.ReadKey();

This is fixed in Hamcrest 1.3. The below code compiles and does not generate any warnings:

// given
List<String> list = new ArrayList<String>();
// then
assertThat(list, is(not(empty())));

But if you have to use older version - instead of bugged empty() you could use:

hasSize(greaterThan(0))
(import static org.hamcrest.number.OrderingComparison.greaterThan; or
import static org.hamcrest.Matchers.greaterThan;)

Example:

// given
List<String> list = new ArrayList<String>();
// then
assertThat(list, hasSize(greaterThan(0)));

The most important thing about above solutions is that it does not generate any warnings. The second solution is even more useful if you would like to estimate minimum result size.

Your method can be called and the arraylist can be stored like this

YourClassName class = new YourClassName();
Arraylist<Integer> numbers = class.numbers(); 

This also allows the arraylist to be manipulated further in this class

This answer on super user I think is a better answer. From https://superuser.com/a/573761/67952

"But since you asked for a way without using Before and After, you can use:

Behavior of idle is very similar to simple; however, actual execution of the service program is delayed until all active jobs are dispatched. This may be used to avoid interleaving of output of shell services with the status output on the console. Note that this type is useful only to improve console output, it is not useful as a general unit ordering tool, and the effect of this service type is subject to a 5s time-out, after which the service program is invoked anyway.

Never mind -- I'm an idiot. I just needed <xsl:value-of select="/root/Image/node()"/>

I got this error when loading '|' separated CSV file although there were no '"' characters in my input file. It turned out that I forgot to specify FORMAT:

COPY ... FROM ... WITH (FORMAT CSV, DELIMITER '|').

For example, if you have multiple whereIn OR whereIn conditions and you want to put brackets, do it like this:

$getrecord = DiamondMaster::where('is_delete','0')->where('user_id',Auth::user()->id);
if(!empty($request->stone_id))
{
    $postdata = $request->stone_id;
    $certi_id =trim($postdata,",");
    $getrecord = $getrecord->whereIn('id',explode(",", $certi_id))
                           ->orWhereIn('Certi_NO',explode(",", $certi_id));     
}
$getrecord = $getrecord->get();

Generically, do/while is good for any sort of loop construct where one must execute the loop at least once. It is possible to emulate this sort of looping through either a straight while or even a for loop, but often the result is a little less elegant. I'll admit that specific applications of this pattern are fairly rare, but they do exist. One which springs to mind is a menu-based console application:

do {
    char c = read_input();

    process_input(c);
} while (c != 'Q');

You need to bind the modal hide call to the onclick event.

Assuming you are using jQuery you can do that with:

$('#closemodal').click(function() {
    $('#modalwindow').modal('hide');
});

Also make sure the click event is bound after the document has finished loading:

$(function() {
   // Place the above code inside this block
});
enter code here

If you want to change background color, try this:

plt.rcParams['figure.facecolor'] = 'white'

Another one line solution:

array1.concat(array2).filter((item, index, currentArr) => currentArr.lastIndexOf(item) == currentArr.indexOf(item)).length == 0;

or

[...array1, ...array2].filter((item, index, currentArr) => currentArr.lastIndexOf(item) == currentArr.indexOf(item)).length == 0;

You can also add

<Resource 
auth="Container" 
driverClassName="org.apache.derby.jdbc.EmbeddedDriver" 
maxActive="20" 
maxIdle="10" 
maxWait="-1" 
name="ds/flexeraDS" 
type="javax.sql.DataSource" 
url="jdbc:derby:flexeraDB;create=true" 
/> 

under META-INF/context.xml file (This will be only at application level).

You can get a passphrase out of an arbitrary password by using a cryptographic hash function (NOT Python's builtin hash) like SHA-1 or SHA-256. Python includes support for both in its standard library:

import hashlib

hashlib.sha1("this is my awesome password").digest() # => a 20 byte string
hashlib.sha256("another awesome password").digest() # => a 32 byte string

You can truncate a cryptographic hash value just by using [:16] or [:24] and it will retain its security up to the length you specify.

From book :

Choose a Random Row Using an Offset

Still another technique that avoids problems found in the preceding alternatives is to count the rows in the data set and return a random number between 0 and the count. Then use this number as an offset when querying the data set

$rand = "SELECT ROUND(RAND() * (SELECT COUNT(*) FROM Bugs))";
$offset = $pdo->query($rand)->fetch(PDO::FETCH_ASSOC);
$sql = "SELECT * FROM Bugs LIMIT 1 OFFSET :offset";
$stmt = $pdo->prepare($sql);
$stmt->execute( $offset );
$rand_bug = $stmt->fetch();

Use this solution when you can’t assume contiguous key values and you need to make sure each row has an even chance of being selected.

Ok, since my attempt to post my solution in a comment failed, here's what I was trying to say. I could do exactly what I wanted from native Python (on Windows, not anywhere else though) with the following code:

import msvcrt 

def kbfunc(): 
   x = msvcrt.kbhit()
   if x: 
      ret = ord(msvcrt.getch()) 
   else: 
      ret = 0 
   return ret

Referencing

& is the reference operator. It will refer the memory address to the pointer variable.

Example:

int *p;
int a=5;
p=&a; // Here Pointer variable p refers to the address of integer variable a.

Dereferencing

Dereference operator * is used by the pointer variable to directly access the value of the variable instead of its memory address.

Example:

int *p;
int a=5;
p=&a;
int value=*p; // Value variable will get the value of variable a that pointer variable p pointing to.

I don't think it is necessary to "host" the content using the way from the accepted answer. It is too complicated for a normal user with limited developing skills.

Google actually has provided hosting feature without using Drive SDK/API, what you need is just few clicks. Check this out:

http://support.google.com/drive/bin/answer.py?hl=en&answer=2881970

It is the same to the answer of user1557669. However, in step 4, the URL is not correct, it is like:

https://drive.google.com/#folders/...

To get the correct host URL. Right click on the html file (you have to finish 1-3 steps first and put the html in the public shared folder), and select "Details" from the context menu. You will find the hosting URL right close to the bottom of the details panel. It should look like:

https://googledrive.com/host/.../abc.html

Then you can share the link to anyone. Happy sharing.

//if i input 9 it should go to 8?

You still have to work with the elements of the array. You will count 8 elements when looping through the array, but they are still going to be array(0) - array(7).

What is the cause?

The error message is pretty clear: you're trying to access a file, and it's not accessible because another process (or even the same process) is doing something with it (and it didn't allow any sharing).

Debugging

It may be pretty easy to solve (or pretty hard to understand), depending on your specific scenario. Let's see some.

Your process is the only one to access that file
You're sure the other process is your own process. If you know you open that file in another part of your program, then first of all you have to check that you properly close the file handle after each use. Here is an example of code with this bug:

var stream = new FileStream(path, FileAccess.Read);
var reader = new StreamReader(stream);
// Read data from this file, when I'm done I don't need it any more
File.Delete(path); // IOException: file is in use

Fortunately FileStream implements IDisposable, so it's easy to wrap all your code inside a using statement:

using (var stream = File.Open("myfile.txt", FileMode.Open)) {
    // Use stream
}

// Here stream is not accessible and it has been closed (also if
// an exception is thrown and stack unrolled

This pattern will also ensure that the file won't be left open in case of exceptions (it may be the reason the file is in use: something went wrong, and no one closed it; see this post for an example).

If everything seems fine (you're sure you always close every file you open, even in case of exceptions) and you have multiple working threads, then you have two options: rework your code to serialize file access (not always doable and not always wanted) or apply a retry pattern. It's a pretty common pattern for I/O operations: you try to do something and in case of error you wait and try again (did you ask yourself why, for example, Windows Shell takes some time to inform you that a file is in use and cannot be deleted?). In C# it's pretty easy to implement (see also better examples about disk I/O, networking and database access).

private const int NumberOfRetries = 3;
private const int DelayOnRetry = 1000;

for (int i=1; i <= NumberOfRetries; ++i) {
    try {
        // Do stuff with file
        break; // When done we can break loop
    }
    catch (IOException e) when (i <= NumberOfRetries) {
        // You may check error code to filter some exceptions, not every error
        // can be recovered.
        Thread.Sleep(DelayOnRetry);
    }
}

Please note a common error we see very often on StackOverflow:

var stream = File.Open(path, FileOpen.Read);
var content = File.ReadAllText(path);

In this case ReadAllText() will fail because the file is in use (File.Open() in the line before). To open the file beforehand is not only unnecessary but also wrong. The same applies to all File functions that don't return a handle to the file you're working with: File.ReadAllText(), File.WriteAllText(), File.ReadAllLines(), File.WriteAllLines() and others (like File.AppendAllXyz() functions) will all open and close the file by themselves.

Your process is not the only one to access that file
If your process is not the only one to access that file, then interaction can be harder. A retry pattern will help (if the file shouldn't be open by anyone else but it is, then you need a utility like Process Explorer to check who is doing what).

Ways to avoid

When applicable, always use using statements to open files. As said in previous paragraph, it'll actively help you to avoid many common errors (see this post for an example on how not to use it).

If possible, try to decide who owns access to a specific file and centralize access through a few well-known methods. If, for example, you have a data file where your program reads and writes, then you should box all I/O code inside a single class. It'll make debug easier (because you can always put a breakpoint there and see who is doing what) and also it'll be a synchronization point (if required) for multiple access.

Don't forget I/O operations can always fail, a common example is this:

if (File.Exists(path))
    File.Delete(path);

If someone deletes the file after File.Exists() but before File.Delete(), then it'll throw an IOException in a place where you may wrongly feel safe.

Whenever it's possible, apply a retry pattern, and if you're using FileSystemWatcher, consider postponing action (because you'll get notified, but an application may still be working exclusively with that file).

Advanced scenarios
It's not always so easy, so you may need to share access with someone else. If, for example, you're reading from the beginning and writing to the end, you have at least two options.

1) share the same FileStream with proper synchronization functions (because it is not thread-safe). See this and this posts for an example.

2) use FileShare enumeration to instruct OS to allow other processes (or other parts of your own process) to access same file concurrently.

using (var stream = File.Open(path, FileMode.Open, FileAccess.Write, FileShare.Read))
{
}

In this example I showed how to open a file for writing and share for reading; please note that when reading and writing overlaps, it results in undefined or invalid data. It's a situation that must be handled when reading. Also note that this doesn't make access to the stream thread-safe, so this object can't be shared with multiple threads unless access is synchronized somehow (see previous links). Other sharing options are available, and they open up more complex scenarios. Please refer to MSDN for more details.

In general N processes can read from same file all together but only one should write, in a controlled scenario you may even enable concurrent writings but this can't be generalized in few text paragraphs inside this answer.

Is it possible to unlock a file used by another process? It's not always safe and not so easy but yes, it's possible.

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

$("#ddlMultiselect").val('').trigger("change");

for multi-select drop-down, it will clear displayed text.

The CPU can only understand machine code indeed. For interpreted programs, the ultimate goal of an interpreter is to "interpret" the program code into machine code. However, usually a modern interpreted language does not interpret human code directly because it is too inefficient.

The Python interpreter first reads the human code and optimizes it to some intermediate code before interpreting it into machine code. That's why you always need another program to run a Python script, unlike in C++ where you can run the compiled executable of your code directly. For example, c:\Python27\python.exe or /usr/bin/python.

Override this function in your controller

protected override void HandleUnknownAction(string actionName) 
{  TempData["actionName"] = actionName;
   View("urViewName").ExecuteResult(this.ControllerContext);
}

You can also do it this way without the need of Linq:

List<int> numbers = new List<int>( Array.ConvertAll(sNumbers.Split(','), int.Parse) );

// Uses Linq
var numbers = Array.ConvertAll(sNumbers.Split(','), int.Parse).ToList();

The problem with all presented answers it complete lack of taking triggers (and probably other side effects) into account. Solution like

INSERT OR IGNORE ...
UPDATE ...

leads to both triggers executed (for insert and then for update) when row does not exist.

Proper solution is

UPDATE OR IGNORE ...
INSERT OR IGNORE ...

in that case only one statement is executed (when row exists or not).

Maybe you'll be able to set the event handlers programmatically, using something like (pseudocode)

sub myhandler(eventsource)
  process(eventsource.value)
end sub

for each cell
  cell.setEventHandler(myHandler)

But i dont know the syntax for achieving this in VB/VBA, or if is even possible.

If you want to call a function on clicking of submit button then you have
to use ajax or jquery,if you want to call your php function after submission of form you can do that as :

<html>
<body>
<form method="post" action="display()">
<input type="text" name="studentname">
<input type="submit" value="click">
</form>
<?php
function display()
{
echo "hello".$_POST["studentname"];
}
if($_SERVER['REQUEST_METHOD']=='POST')
{
       display();
} 
?>
</body>
</html>

Use execute_script, here's a python example:

from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://stackoverflow.com/questions/7794087/running-javascript-in-selenium-using-python") 
driver.execute_script("document.getElementsByClassName('comment-user')[0].click()")

The t indicates text mode, meaning that \n characters will be translated to the host OS line endings when writing to a file, and back again when reading. The flag is basically just noise, since text mode is the default.

Other than U, those mode flags come directly from the standard C library's fopen() function, a fact that is documented in the sixth paragraph of the python2 documentation for open().

As far as I know, t is not and has never been part of the C standard, so although many implementations of the C library accept it anyway, there's no guarantee that they all will, and therefore no guarantee that it will work on every build of python. That explains why the python2 docs didn't list it, and why it generally worked anyway. The python3 docs make it official.

For repeating an action in the future, there is the built in setInterval function that you can use instead of setTimeout.
It has a similar signature, so the transition from one to another is simple:

setInterval(function() {
    // do stuff
}, duration);

To set the default to UTF-8, you want to add the following to my.cnf/my.ini

[client]
default-character-set=utf8mb4

[mysql]
default-character-set=utf8mb4


[mysqld]
collation-server = utf8mb4_unicode_520_ci
init-connect='SET NAMES utf8mb4'
character-set-server = utf8mb4

If you want to change the character set for an existing DB, let me know... your question didn't specify it directly so I am not sure if that's what you want to do.

Edit: I replaced utf8 with utf8mb4 in the original answer due to utf8 only being a subset of UTF-8. MySQL and MariaDB both call UTF-8 utf8mb4.

I had this when requested SDK version didn't match the dependencies. You can click the line highlighted and fix this clicking the red light bulb. No need to find the actual version, just let the IDE figure it out for you. And add google repo to maven config.
