The reason behind this is that meanwhile creating your own class, you had also accepted to create a default class as prescribed by your IDE and after writing your code in your own class, you are getting such an error. In order to eliminate this, go to the PROJECT folder ? src ? Default package. Keep only one class (in which you had written code) and delete others.

After that, run your program and it will definitely run without any error.

For those looking for a solution that works with static exports, try the solution listed here: https://github.com/zeit/next.js/issues/4804#issuecomment-460754433

In a nutshell, router.query works only with SSR applications, but router.asPath still works.

So can either configure the query pre-export in next.config.js with exportPathMap (not dynamic):

    return {
      '/': { page: '/' },
      '/about': { page: '/about', query: { title: 'about-us' } }
    }
  }

Or use router.asPath and parse the query yourself with a library like query-string:

import { withRouter } from "next/router";
import queryString from "query-string";

export const withPageRouter = Component => {
  return withRouter(({ router, ...props }) => {
    router.query = queryString.parse(router.asPath.split(/\?/)[1]);

    return <Component {...props} router={router} />;
  });
};

I just changed:

  <base href="/">

to this:

  <base href="/something.html/">

don't forget ending with /

yum update

helped me out. After I had

wget: symbol lookup error: wget: undefined symbol: psl_latest

Fix it in 20 seconds:

This solution belongs to @Arseniy-II, I have just simplified it into a function.

function _scrollTo(selector, yOffset = 0){
  const el = document.querySelector(selector);
  const y = el.getBoundingClientRect().top + window.pageYOffset + yOffset;

  window.scrollTo({top: y, behavior: 'smooth'});
}

Usage (you can open up the console right here in StackOverflow and test it out):

_scrollTo('#question-header', 0);

I'm currently using this in production and it is working just fine.

To get exactly the same thing as base_url of codeigniter, you can do:

var base_url = window.location.origin + '/' + window.location.pathname.split ('/') [1] + '/';

this will be more useful if you work on pure Javascript file.

For me, select2.min.js file worked instead of select2.full.min.js. I have manually define files which I have copied from dist folder that I got from github page. Also make sure that you have one jQuery(document).ready(...) definition and jquery file imported before select2 file.

set "PathName=X:\Web Content Mgmt\Completed Filtering\2013_Folder"
set "comd=dir /b /s *.zip"
cd /d "%PathName%"
%comd%

purls $.params() used without a parameter will give you a key-value object of the parameters.

jQuerys $.param() will build a querystring from the supplied object/array.

var params = parsedUrl.param();
delete params["page"];

var newUrl = "?page=" + $(this).val() + "&" + $.param(params);

Update
I've no idea why I used delete here...

var params = parsedUrl.param();
params["page"] = $(this).val();

var newUrl = "?" + $.param(params);

Translated:

It happened the same to me and in my case in particular was because the package.json was wrong. example:

{
   "name": "app",
   "version": "0.0.0",
   "description": "any description",
   "main": "index.js",
   "author": "me", ->wrong
}

The last comma was left over and it gave me error any instalacción with npm in this proyect

then:

{
   "name": "app",
   "version": "0.0.0",
   "description": "any description",
   "main": "index.js",
   "author": "me"
}

I hope it will help.

You can use CurrentDirectory property.

Dim WshShell, strCurDir
Set WshShell = CreateObject("WScript.Shell")
strCurDir    = WshShell.CurrentDirectory
WshShell.Run strCurDir & "\attribute.exe", 0
Set WshShell = Nothing

You cannot echo an array. Must use print_r instead.

<?php
$result = $conn->query("Select * from tbl");
$row = $result->fetch_assoc();
print_r ($row);
?>

For Bootstrap 3:

var url = window.location;
// Will only work if string in href matches with location
$('ul.nav a[href="'+ url +'"]').parent().addClass('active');

// Will also work for relative and absolute hrefs
$('ul.nav a').filter(function() {
    return this.href == url;
}).parent().addClass('active');

Update

For Bootstrap 4:

var url = window.location;
// Will only work if string in href matches with location
$('ul.navbar-nav a[href="'+ url +'"]').parent().addClass('active');

// Will also work for relative and absolute hrefs
$('ul.navbar-nav a').filter(function() {
    return this.href == url;
}).parent().addClass('active');

response.writeHead(301,
  {Location: 'http://whateverhostthiswillbe:8675/'+newRoom}
);
response.end();

You need to use font-url in your @font-face block, not url

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

as well as this line in application.rb, as you mentioned (for fonts in app/assets/fonts

config.assets.paths << Rails.root.join("app", "assets", "fonts")

Or shorter:

$("form#data").submit(function() {
    var formData = new FormData(this);
    $.post($(this).attr("action"), formData, function() {
        // success    
    });
    return false;
});

here it's a simple:

File file = new File(path);
int size = (int) file.length();
byte[] bytes = new byte[size];
try {
    BufferedInputStream buf = new BufferedInputStream(new FileInputStream(file));
    buf.read(bytes, 0, bytes.length);
    buf.close();
} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Add permission in manifest.xml:

 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

What you're doing is appending a "1" (the string) to your URL. If you want page 1.html link to page 2.html you need to take the 1 out of the string, add one to it, then reassemble the string.

Why not do something like this:

var url = 'http://mywebsite.com/1.html';
var pageNum = parseInt( url.split("/").pop(),10 );
var nextPage = 'http://mywebsite.com/'+(pageNum+1)+'.html';

nextPage will contain the url http://mywebsite.com/2.html in this case. Should be easy to put in a function if needed.

You can use the parse method from the URL module in the request callback.

var http = require('http');
var url = require('url');

// Configure our HTTP server to respond with Hello World to all requests.
var server = http.createServer(function (request, response) {
  var queryData = url.parse(request.url, true).query;
  response.writeHead(200, {"Content-Type": "text/plain"});

  if (queryData.name) {
    // user told us their name in the GET request, ex: http://host:8000/?name=Tom
    response.end('Hello ' + queryData.name + '\n');

  } else {
    response.end("Hello World\n");
  }
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(8000);

I suggest you read the HTTP module documentation to get an idea of what you get in the createServer callback. You should also take a look at sites like http://howtonode.org/ and checkout the Express framework to get started with Node faster.

Is there a wrapper module on top of the http to more easily handle processing http responses from a node application?

Redirection logic in request

In Java 8:

Arrays.sort(files, (a, b) -> a.getName().compareTo(b.getName()));

Reverse order:

Arrays.sort(files, (a, b) -> -a.getName().compareTo(b.getName()));

You can compile with either Cygwin's g++ or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll (and others) PATH to the system Windows PATH, before any cygwin style paths.

Thus add: ;C:\cygwin64\bin to the end of your Windows system PATH variable.

Also, to compile for use in CMD or PowerShell, you may need to use:

x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe

_{(This invokes the cross-compiler, if installed.)}

This can be solved also with POST/REDIRECT/GET pattern.
Which is more elegant:
How do I reload a page without a POSTDATA warning in Javascript?

First, we need to filter the XML so as to parse that change objects become array

//catch xml
$xmlElement = file_get_contents ('php://input');
//change become array
$Data = (array)simplexml_load_string($xmlElement);
//and see
print_r($Data);

You can use substr

for example:

new Date().getFullYear().toString().substr(-2)

The set statement doesn't treat spaces the way you expect; your variable is really named Pathname[space] and is equal to [space]C:\Program Files.

Remove the spaces from both sides of the = sign, and put the value in double quotes:

set Pathname="C:\Program Files"

Also, if your command prompt is not open to C:\, then using cd alone can't change drives.

Use

cd /d %Pathname%

or

pushd %Pathname%

instead.

               if(referrer.equals("Setting.jsp")){                     
                   function goBack() {  
                        window.history.go();                            
                    }

                        window.history.forward();
                        function noBack() {
                        window.history.forward(); 
                    }
                   }
    }); 

using this you can avoid load previous page load

I learned from this link, if you are using XP or greater that this will simply work by itself:

SET params = %~1

I could not get any of the other solutions here to work on Windows 7.

To iterate over them, I did this:

FOR %%A IN (%params%) DO (    
   ECHO %%A    
)

Note: You will only get double quotes if you pass in arguments separated by a space typically.

A little more reusable function:

beginsWith = function(needle, haystack){
    return (haystack.substr(0, needle.length) == needle);
}

open() will be called at the end of each of the fopen() family functions. open() is a system call and fopen() are provided by libraries as a wrapper functions for user easy of use

Wouldn't unlinking it and creating the new one do the same thing in the end anyway?

My take on it...obviously, you've got to do something with the data you read in. If it involves writing it to the sheet, that'll be deadly slow with a normal For Loop. I came up with the following based upon a rehash of some of the items there, plus some help from the Chip Pearson website.

Reading in the text file (assuming you don't know the length of the range it will create, so only the startingCell is given):

Public Sub ReadInPlainText(startCell As Range, Optional textfilename As Variant)

   If IsMissing(textfilename) Then textfilename = Application.GetOpenFilename("All Files (*.*), *.*", , "Select Text File to Read")
   If textfilename = "" Then Exit Sub

   Dim filelength As Long
   Dim filenumber As Integer
   filenumber = FreeFile
   filelength = filelen(textfilename)
   Dim text As String
   Dim textlines As Variant

   Open textfilename For Binary Access Read As filenumber

   text = Space(filelength)
   Get #filenumber, , text

   'split the file with vbcrlf
   textlines = Split(text, vbCrLf) 

   'output to range
   Dim outputRange As Range
   Set outputRange = startCell
   Set outputRange = outputRange.Resize(UBound(textlines), 1)
   outputRange.Value = Application.Transpose(textlines)

   Close filenumber
 End Sub

Conversely, if you need to write out a range to a text file, this does it quickly in one print statement (note: the file 'Open' type here is in text mode, not binary..unlike the read routine above).

Public Sub WriteRangeAsPlainText(ExportRange As Range, Optional textfilename As Variant)
   If IsMissing(textfilename) Then textfilename = Application.GetSaveAsFilename(FileFilter:="Text Files (*.txt), *.txt")
   If textfilename = "" Then Exit Sub

   Dim filenumber As Integer
   filenumber = FreeFile
   Open textfilename For Output As filenumber

   Dim textlines() As Variant, outputvar As Variant

   textlines = Application.Transpose(ExportRange.Value)
   outputvar = Join(textlines, vbCrLf)
   Print #filenumber, outputvar
   Close filenumber
End Sub

If the file is read-only, just remove it and it should work again.

PURE JavaScript:

Creating the XMLHttpRequest:

function getHTTPObject() {
    /* Crea el objeto AJAX. Esta funcion es generica para cualquier utilidad de este tipo, 
       por lo que se puede copiar tal como esta aqui */
    var xmlhttp = false;
    /* No mas soporte para Internet Explorer
    try { // Creacion del objeto AJAX para navegadores no IE
        xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
    } catch(nIE) {
        try { // Creacion del objet AJAX para IE
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        } catch(IE) {
            if (!xmlhttp && typeof XMLHttpRequest!='undefined') 
                xmlhttp = new XMLHttpRequest();
        }
    }
    */
    xmlhttp = new XMLHttpRequest();
    return xmlhttp; 
}

JavaScript function to Send the info via POST:

function sendInfo() {
    var URL = "somepage.html"; //depends on you
    var Params = encodeURI("var1="+val1+"var2="+val2+"var3="+val3);
    console.log(Params);
    var ajax = getHTTPObject();     
    ajax.open("POST", URL, true); //True:Sync - False:ASync
    ajax.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
    ajax.setRequestHeader("Content-length", Params.length);
    ajax.setRequestHeader("Connection", "close");
    ajax.onreadystatechange = function() { 
        if (ajax.readyState == 4 && ajax.status == 200) {
            alert(ajax.responseText);
        } 
    }
    ajax.send(Params);
}

Cross-browser URL parsing, works around the relative path problem for IE 6, 7, 8 and 9:

function ParsedUrl(url) {
    var parser = document.createElement("a");
    parser.href = url;

    // IE 8 and 9 dont load the attributes "protocol" and "host" in case the source URL
    // is just a pathname, that is, "/example" and not "http://domain.com/example".
    parser.href = parser.href;

    // IE 7 and 6 wont load "protocol" and "host" even with the above workaround,
    // so we take the protocol/host from window.location and place them manually
    if (parser.host === "") {
        var newProtocolAndHost = window.location.protocol + "//" + window.location.host;
        if (url.charAt(1) === "/") {
            parser.href = newProtocolAndHost + url;
        } else {
            // the regex gets everything up to the last "/"
            // /path/takesEverythingUpToAndIncludingTheLastForwardSlash/thisIsIgnored
            // "/" is inserted before because IE takes it of from pathname
            var currentFolder = ("/"+parser.pathname).match(/.*\//)[0];
            parser.href = newProtocolAndHost + currentFolder + url;
        }
    }

    // copies all the properties to this object
    var properties = ['host', 'hostname', 'hash', 'href', 'port', 'protocol', 'search'];
    for (var i = 0, n = properties.length; i < n; i++) {
      this[properties[i]] = parser[properties[i]];
    }

    // pathname is special because IE takes the "/" of the starting of pathname
    this.pathname = (parser.pathname.charAt(0) !== "/" ? "/" : "") + parser.pathname;
}

Usage (demo JSFiddle here):

var myUrl = new ParsedUrl("http://www.example.com:8080/path?query=123#fragment");

Result:

{
    hash: "#fragment"
    host: "www.example.com:8080"
    hostname: "www.example.com"
    href: "http://www.example.com:8080/path?query=123#fragment"
    pathname: "/path"
    port: "8080"
    protocol: "http:"
    search: "?query=123"
}

When working under Linux the syntax below is right:

cd ~/My\ Code

However when you're executing your file, use the syntax below:

$ . cdcode

(just '.' and not './')

This seems to work. The above doesn't in Excel 2010.

Function StripFilename(sPathFile As String) As String
'given a full path and file, strip the filename off the end and return the path
Dim filesystem As Object

Set filesystem = CreateObject("Scripting.FilesystemObject")

StripFilename = filesystem.GetParentFolderName(sPathFile) & "\"

Exit Function

End Function

You can use the ATL text conversion macros to convert a narrow (char) string to a wide (wchar_t) one. For example, to convert a std::string:

#include <atlconv.h>
...
std::string str = "Hello, world!";
CA2W pszWide(str.c_str());
loadU(pszWide);

You can also specify a code page, so if your std::string contains UTF-8 chars you can use:

CA2W pszWide(str.c_str(), CP_UTF8);

Very useful but Windows only.

You can either use the first one or try the code below which is equally efficient

sort(&a[0], &a[n], greater<int>());

IN your view insert

@Html.ValidationMessage("Error")

then in the controller after you use new in your model

var model = new yourmodel();
try{
[...]
}catch(Exception ex){
ModelState.AddModelError("Error", ex.Message);
return View(model);
}

The accepted answer works, and may be faster, but SQL 2012 and above have a more easily understood method:

SELECT cast(format(GETDATE(), 'yyyy-MM-01') as Date)

EDIT: If you are using a Dockerfile for deployments these are the steps you need to take to resolve this issue.

Change your Dockerfile to include the following:

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
ENV PATH $PATH:/root/.dotnet/tools
RUN dotnet tool install -g dotnet-ef --version 3.1.1

Also change your dotnet ef commands to be dotnet-ef

def func(a, b, c, d):
 return a + b * c % d

map(lambda x: func(*x), [[1,2,3,4], [5,6,7,8]])

By wrapping the function call with a lambda and using the star unpack, you can do map with arbitrary number of arguments.

This worked for me:

git branch -r | awk '{print $1}' | egrep -v -f /dev/fd/0 <(git branch -vv | grep origin) | awk '{print $1}' | xargs git branch -d

Try Window > Open Perspective > Java Browsing or some other Java perspectives

This is how I handle this, without using exceptions.

import sys
if sys.version_info.major > 2:  # Python 3 or later
    from urllib.parse import quote
else:  # Python 2
    from urllib import quote

That is illegal syntax. It is not an optional thing for you to return a variable. You MUST return a variable of the type you specify in your method.

public String myMethod()
{
    if(condition)
    {
       return x;
    }
}

You are effectively saying, I promise any class can use this method(public) and I promise it will always return a String(String).

Then you are saying IF my condition is true I will return x. Well that is too bad, there is no IF in your promise. You promised that myMethod will ALWAYS return a String. Even if your condition is ALWAYS true the compiler has to assume that there is a possibility of it being false. Therefore you always need to put a return at the end of your non-void method outside of any conditions JUST IN CASE all of your conditions fail.

public String myMethod()
{
    if(condition)
    {
       return x;
    }
  return ""; //or whatever the default behavior will be if all of your conditions fail to return.
}

In my case, it was neither systemd nor a cron job, but it was snap. So I had to run:

sudo snap stop docker
sudo snap remove docker

... and the last command actually never ended, I don't know why: this snap thing is really a pain. So I also ran:

sudo apt purge snap

:-)

This code works great for preparing the dynamic values Array for spinner in Android:

    List<String> yearStringList = new ArrayList<>();
    yearStringList.add("2017");
    yearStringList.add("2018");
    yearStringList.add("2019");


    String[] yearStringArray = (String[]) yearStringList.toArray(new String[yearStringList.size()]);

I was looking for the same thing when I came here, but the lack of a generic "upsert" function botherd me a bit so I thought you could just pass the update and insert sql as arguments on that function form the manual

that would look like this:

CREATE FUNCTION upsert (sql_update TEXT, sql_insert TEXT)
    RETURNS VOID
    LANGUAGE plpgsql
AS $$
BEGIN
    LOOP
        -- first try to update
        EXECUTE sql_update;
        -- check if the row is found
        IF FOUND THEN
            RETURN;
        END IF;
        -- not found so insert the row
        BEGIN
            EXECUTE sql_insert;
            RETURN;
            EXCEPTION WHEN unique_violation THEN
                -- do nothing and loop
        END;
    END LOOP;
END;
$$;

and perhaps to do what you initially wanted to do, batch "upsert", you could use Tcl to split the sql_update and loop the individual updates, the preformance hit will be very small see http://archives.postgresql.org/pgsql-performance/2006-04/msg00557.php

the highest cost is executing the query from your code, on the database side the execution cost is much smaller

In my case the route in my router was:

Route::post('/new-order', 'Api\OrderController@initiateOrder')->name('newOrder');

and from the client app I was posting the request to:

https://my-domain/api/new-order/

So, because of the trailing slash I got a 405. Hope it helps someone

Try the freeware iOS Console. Just download, launch, connect your device -- et voila!

Another option is to create a self-signed certificate that allows you to specify the domain name per website. This means you can use it across many domain names.

In IIS Manager

1. Click machine name node
2. Open Server Certificates
3. In Actions panel, choose 'Create Self-Signed Certificate'
4. In 'Specify a friendly name...' name it *Dev (select 'Personal' from type list)
5. Save

Now, on your website in IIS...

1. Manage the bindings
2. Create a new binding for Https
3. Choose your self-signed certificate from the list
4. Once selected, the domain name box will become enabled and you'll be able to input your domain name.

This solution will split into two columns and divide the content half in one line half in the other. This comes in handy if you are working with data that gets loaded into the first column, and want it to flow evenly every time. :). You can play with the amount that gets put into the first col. This will work with lists as well.

Enjoy.

For IIS 7+, as well as adding the httpRuntime maxRequestLength setting you also need to add:

  <system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="52428800" /> <!--50MB-->
      </requestFiltering>
    </security>
  </system.webServer>

Or in IIS (7):

• Select the website you want enable to accept large file uploads.
• In the main window double click 'Request filtering'
• Select "Edit Feature Settings"
• Modify the "Maximum allowed content length (bytes)"

Here is another example showing the use of gather from tidyr. You can select the columns to gather either by removing them individually (as I do here), or by including the years you want explicitly.

Note that, to handle the commas (and X's added if check.names = FALSE is not set), I am also using dplyr's mutate with parse_number from readr to convert the text values back to numbers. These are all part of the tidyverse and so can be loaded together with library(tidyverse)

wide %>%
  gather(Year, Value, -Code, -Country) %>%
  mutate(Year = parse_number(Year)
         , Value = parse_number(Value))

Returns:

   Code     Country Year Value

Simply remove the dot for the relative import and do:

My application is a web application (ASP.NET MVC) and I had to change the application pool to run under LocalSystem instead of ApplicationPoolIdentity. To do this:

1. Open IIS Manager
2. Find the Application Pool your site is running under.
3. Click Advanced Settings from the actions
4. Change Identity to LocalSystem

I have no idea why this fixes the issue.

=INDEX(GoogleFinance("CURRENCY:" & "EUR" & "USD", "price", A2), 2, 2)

where A2 is the cell with a date formatted as date.

Replace "EUR" and "USD" with your currency pair.

Table relationship vs. entity relationship

In a relational database system, a one-to-many table relationship looks as follows:

Note that the relationship is based on the Foreign Key column (e.g., post_id) in the child table.

So, there is a single source of truth when it comes to managing a one-to-many table relationship.

Now, if you take a bidirectional entity relationship that maps on the one-to-many table relationship we saw previously:

If you take a look at the diagram above, you can see that there are two ways to manage this relationship.

In the Post entity, you have the comments collection:

@OneToMany(
    mappedBy = "post",
    cascade = CascadeType.ALL,
    orphanRemoval = true
)
private List<PostComment> comments = new ArrayList<>();

And, in the PostComment, the post association is mapped as follows:

@ManyToOne(
    fetch = FetchType.LAZY
)
@JoinColumn(name = "post_id")
private Post post;

Because there are two ways to represent the Foreign Key column, you must define which is the source of truth when it comes to translating the association state change into its equivalent Foreign Key column value modification.

MappedBy

The mappedBy attribute tells that the @ManyToOne side is in charge of managing the Foreign Key column, and the collection is used only to fetch the child entities and to cascade parent entity state changes to children (e.g., removing the parent should also remove the child entities).

Synchronize both sides of a bidirectional association

Now, even if you defined the mappedBy attribute and the child-side @ManyToOne association manages the Foreign Key column, you still need to synchronize both sides of the bidirectional association.

The best way to do that is to add these two utility methods:

public void addComment(PostComment comment) {
    comments.add(comment);
    comment.setPost(this);
}

public void removeComment(PostComment comment) {
    comments.remove(comment);
    comment.setPost(null);
}

The addComment and removeComment methods ensure that both sides are synchronized. So, if we add a child entity, the child entity needs to point to the parent and the parent entity should have the child contained in the child collection.

You probably need to wrap the UNION in a sub-SELECT and apply the WHERE clause afterward:

SELECT * FROM (
    SELECT * FROM Table1 WHERE Field1 = Value1
    UNION
    SELECT * FROM Table2 WHERE Field1 = Value2
) AS t WHERE Field2 = Value3

Basically, the UNION is looking for two complete SELECT statements to combine, and the WHERE clause is part of the SELECT statement.

It may make more sense to apply the outer WHERE clause to both of the inner queries. You'll probably want to benchmark the performance of both approaches and see which works better for you.

<div style="text-align:center;">
    <img src="queuedError.jpg" style="margin:auto; width:200px;" />
</div>

I don't think that solution would work anyways because you will see some error message in your error log file.

The solution was a lot easier than what I thought.

simply, open the following path to your php5-fpm

sudo nano /etc/php5/fpm/pool.d/www.conf

or if you're the admin 'root'

nano /etc/php5/fpm/pool.d/www.conf

Then find this line and uncomment it:

listen.allowed_clients = 127.0.0.1

This solution will make you be able to use listen = 127.0.0.1:9000 in your vhost blocks

like this: fastcgi_pass 127.0.0.1:9000;

after you make the modifications, all you need is to restart or reload both Nginx and Php5-fpm

Php5-fpm

sudo service php5-fpm restart

or

sudo service php5-fpm reload

Nginx

sudo service nginx restart

or

sudo service nginx reload

From the comments:

Also comment

;listen = /var/run/php5-fpm.sock 

and add

listen = 9000

You can use this regex to get the yyyy-MM-dd format:

((?:19|20)\\d\\d)-(0?[1-9]|1[012])-([12][0-9]|3[01]|0?[1-9])

You can find example for date validation: How to validate date with regular expression.

In Linux Ubuntu(maybe also another - it's not tested) distribution with PHP 5 on board, you can use:

sudo php5dismod xdebug

And with PHP 7

sudo phpdismod xdebug

And after that, please restart the server:

sudo service apache2 restart

If the IBM mainframe JCL has some extra characters or numbers at the end of the name of unix script being called then it can throw such error.

I feel this can be elegantly solved using bottleneck

See basic sample below:

import numpy as np
import bottleneck as bn

a = np.random.randint(4, 1000, size=100)
mm = bn.move_mean(a, window=5, min_count=1)

• "mm" is the moving mean for "a".

• "window" is the max number of entries to consider for moving mean.

• "min_count" is min number of entries to consider for moving mean (e.g. for first few elements or if the array has nan values).

The good part is Bottleneck helps to deal with nan values and it's also very efficient.

Use this

<input type="checkbox" name="checkbox" id="checkbox_id" value="value">
<label for="checkbox_id" id="checkbox_lbl">Text</label>


$("#checkbox_lbl").click(function(){ 
    if($("#checkbox_id").is(':checked'))
        $("#checkbox_id").removAttr('checked');
    else
       $("#checkbox_id").attr('checked');
    });
});

The Gutenberg Project hosts Webster's Unabridged English Dictionary plus many other public domain literary works. Actually it looks like they've got several versions of the dictionary hosted with copyright from different years. The one I linked has a 2009 copyright. You may want to poke around the site and investigate the different versions of Webster's dictionary.

I use this as a daily scheduled task to hide users disabled in AD from the Global Address List

$mailboxes = get-user | where {$_.UserAccountControl -like '*AccountDisabled*' -and $_.RecipientType -eq 'UserMailbox' } | get-mailbox  | where {$_.HiddenFromAddressListsEnabled -eq $false}

foreach ($mailbox in $mailboxes) { Set-Mailbox -HiddenFromAddressListsEnabled $true -Identity $mailbox }

just change the containing package of your applicationContext.xml file.
 applicationContext.xml must be in src package not in your project package.
 e.g. 
     src(main package)
         com.yourPackageName(package within src)
         classes etc.
     applicationContext.xml(within src but outside of yourPackage or we can say 
                            parallel to yourPackage name)

If you're using the Prototype JavaScript framework then you can use the focusFirstElement method:

Form.focusFirstElement(document.forms[0]);

Build system independent method

make SHELL='sh -x'

is another option. Sample Makefile:

a:
    @echo a

Output:

+ echo a
a

This sets the special SHELL variable for make, and -x tells sh to print the expanded line before executing it.

One advantage over -n is that is actually runs the commands. I have found that for some projects (e.g. Linux kernel) that -n may stop running much earlier than usual probably because of dependency problems.

One downside of this method is that you have to ensure that the shell that will be used is sh, which is the default one used by Make as they are POSIX, but could be changed with the SHELL make variable.

Doing sh -v would be cool as well, but Dash 0.5.7 (Ubuntu 14.04 sh) ignores for -c commands (which seems to be how make uses it) so it doesn't do anything.

make -p will also interest you, which prints the values of set variables.

CMake generated Makefiles always support VERBOSE=1

As in:

mkdir build
cd build
cmake ..
make VERBOSE=1

Dedicated question at: Using CMake with GNU Make: How can I see the exact commands?

For me, this was caused by the project both directly and indirectly (through another dependency) referencing two different builds of Bouncy Castle that had different assembly names. One of the Bouncy Castle builds was the NuGet package, the other one was a debug build of the source downloaded from GitHub. Both were nominally version 1.8.1, but the project settings of the GitHub code set the assembly name to BouncyCastle whereas the NuGet package had the assembly name BouncyCastle.Crypto. Changing the project settings, thus aligning the assembly names, fixed the problem.

That is not possible, but you can add an anonymous initializer like this:

final int anInt = ...;
Object a = new Class1()
{
  {
    System.out.println(anInt);
  }

  void someNewMethod() {
  }
};

Don't forget final on declarations of local variables or parameters used by the anonymous class, as i did it for anInt.

I struggled to understand the proxy settings for websockets for https therefore let me put clarity here what i realized.

First you need to enable proxy and proxy_wstunnel apache modules and the apache configuration file will look like this.

<IfModule mod_ssl.c>
    <VirtualHost _default_:443>
      ServerName www.example.com
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/your_project_public_folder

      SSLEngine on
      SSLCertificateFile    /etc/ssl/certs/path_to_your_ssl_certificate
      SSLCertificateKeyFile /etc/ssl/private/path_to_your_ssl_key

      <Directory /var/www/your_project_public_folder>
              Options Indexes FollowSymLinks
              AllowOverride All
              Require all granted
              php_flag display_errors On
      </Directory>
      ProxyRequests Off 
      ProxyPass /wss/  ws://example.com:port_no

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
    </VirtualHost>
</IfModule>

in your frontend application use the url "wss://example.com/wss/" this is very important mostly if you are stuck with websockets you might be making mistake in the front end url. You probably putting url wrongly like below.

wss://example.com:8080/wss/ -> port no should not be mentioned
ws://example.com/wss/ -> url should start with wss only.
wss://example.com/wss -> url should end with / -> most important

also interesting part is the last /wss/ is same as proxypass value if you writing proxypass /ws/ then in the front end you should write /ws/ in the end of url.

I was working on Xamarin project and as always, deleting obj folder and rebuilding solved my issue, the namespace my VS was not recognizing was a code in my own project BTW

A for loop is useful when you have an indication or determination, in advance, of how many times you want a loop to run. As an example, if you need to perform a process for each day of the week, you know you want 7 loops.

A foreach loop is when you want to repeat a process for all pieces of a collection or array, but it is not important specifically how many times the loop runs. As an example, you are formatting a list of favorite books for users. Every user may have a different number of books, or none, and we don't really care how many it is, we just want the loop to act on all of them.

I had the same issue when I changed the home directory of one use. In my case it was because of selinux. I used the below to fix the issue:

selinuxenabled 0
setenforce 0

You are asking for the value at key 0 of $votes. It is an array that does not contain that key.

The array $votes is not set, so when PHP is trying to access the key 0 of the array, it encounters an undefined offset for [0] and [1] and throws the error.

If you have an array:

$votes = array('1','2','3');

We can now access:

$votes[0];
$votes[1];
$votes[2];

If we try and access:

$votes[3];

We will get the error "Notice: Undefined offset: 3"

<div style="float: left;">Left Div</div>
<div style="float: right;">Right Div</div>

I required only one instance of the vertical padding, so I inserted this line in the appropriate place to avoid adding more to the css. <div style="margin-top:5px"></div>

XSD files are used to validate that XML files conform to a certain format.

In that respect they are similar to DTDs that existed before them.

The main difference between XSD and DTD is that XSD is written in XML and is considered easier to read and understand.

You have to install it explixitly using the python package manager as

1. pip install openpyxl for Python 2
2. pip3 install openpyxl for Python 3

from hours_t

Comment from answer: "make sure you use the same open connection for all the database calls inside the transaction. – Magnus"

Our users are stored in a separate db from the data I was working with in the transactions. Opening the db connection to get the user was causing this error for me. Moving the other db connection and user lookup outside of the transaction scope fixed the error.

#code to insert and read dictionary element from csv file
import csv

    list=[]
    for i in range(m):
        keys=int(input("Enter id :"))
        list.append(keys)
        values=input("Enter Name :")
        mydict[keys]=values

    with open('File1.csv',"w") as csvfile:
        writer = csv.DictWriter(csvfile, fieldnames=list)
        writer.writeheader()
        writer.writerow(mydict)
        print("Data Inserted")

    keys=input("Enter Id to Search :")
    Id=str(keys)
    with open('File1.csv',"r") as csvfile:

        for row in reader:
            print(row[Id]) #print(row) to display all data

The answer to this question is saying to use display:none and display:block, but this does not help for someone who is trying to use css transitions to show and hide content using the visibility property.

This also drove me crazy, because using display kills any css transitions.

One solution is to add this to the class that's using visibility:

overflow:hidden

For this to work is does depend on the layout, but it should keep the empty content within the div it resides in.

After looking at sp_who, Oracle does not have that ability per se. Oracle has at least 8 processes running which run the db. Like RMON etc.

You can ask the DB which queries are running as that just a table query. Look at the V$ tables.

Quick Example:

SELECT sid,
       opname,
       sofar,
       totalwork,
       units,
       elapsed_seconds,
       time_remaining
FROM v$session_longops
WHERE sofar != totalwork;

For me, i was cloning a project from github which used a version of gradle higher than that which i had installed. I had two choices:

1. Open gradle.wrapper-properties of a project you have that's building successfully, and copy the line that says distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip. Use this to replace the same value in the project that's failing. That should do the trick.

2. Your build might still fail if the gradle version used to build the project is higher than that which you just added. For this you should update the gradle version to the latest.

There's no need to write a custom directive. Angular's documentation is good but not complete. In fact, there is a directive called ngRequired, that takes an Angular expression.

<input type='email'
       name='email'
       ng-model='contact.email' 
       placeholder='[email protected]'
       ng-required='!contact.phone' />

<input type='text'
       ng-model='contact.phone'             
       placeholder='(xxx) xxx-xxxx'
       ng-required='!contact.email' />  

Here's a more complete example: http://jsfiddle.net/uptnx/1/

It's not a good idea to add this kind of thing directly to your $env:WINDIR powershell folders.
The recommended way is to add it to your personal profile:

cd $env:USERPROFILE\Documents
md WindowsPowerShell -ErrorAction SilentlyContinue
cd WindowsPowerShell
New-Item Microsoft.PowerShell_profile.ps1 -ItemType "file" -ErrorAction SilentlyContinue
powershell_ise.exe .\Microsoft.PowerShell_profile.ps1

Now add your alias to the Microsoft.PowerShell_profile.ps1 file that is now opened:

function Do-ActualThing {
    # do actual thing
}

Set-Alias MyAlias Do-ActualThing

Then save it, and refresh the current session with:

. $profile

Note: Just in case, if you get permission issue like

CategoryInfo : SecurityError: (:) [], PSSecurityException + FullyQualifiedErrorId : UnauthorizedAccess

Try the below command and refresh the session again.

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

You also have an error in your css with the exclamation point in this line:

background:rgb(242, 242, 242);!important;

remove the semi-colon before it. However, !important should be used rarely and can largely be avoided.

From Microsoft documentation:

PAGEIOLATCH_SH

Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Shared mode. Long waits may indicate problems with the disk subsystem.

In practice, this almost always happens due to large scans over big tables. It almost never happens in queries that use indexes efficiently.

If your query is like this:

Select * from <table> where <col1> = <value> order by <PrimaryKey>

, check that you have a composite index on (col1, col_primary_key).

If you don't have one, then you'll need either a full INDEX SCAN if the PRIMARY KEY is chosen, or a SORT if an index on col1 is chosen.

Both of them are very disk I/O consuming operations on large tables.

MySQL

COALESCE(field, 'default')

For example:

  SELECT
    t.id,
    COALESCE(d.field, 'default')
  FROM
     test t
  LEFT JOIN
     detail d ON t.id = d.item

Also, you can use multiple columns to check their NULL by COALESCE function. For example:

mysql> SELECT COALESCE(NULL, 1, NULL);
        -> 1
mysql> SELECT COALESCE(0, 1, NULL);
        -> 0
mysql> SELECT COALESCE(NULL, NULL, NULL);
        -> NULL

You called an incorrect method of String class, try:

int tmpInt = 10;
String tmpStr10 = String.valueOf(tmpInt);

You can also do:

int tmpInt = 10;
String tmpStr10 = Integer.toString(tmpInt);

There's no prepackaged "do-while", but the general Python way to implement peculiar looping constructs is through generators and other iterators, e.g.:

import itertools

def dowhile(predicate):
  it = itertools.repeat(None)
  for _ in it:
    yield
    if not predicate(): break

so, for example:

i=7; j=3
for _ in dowhile(lambda: i<j):
  print i, j
  i+=1; j-=1

executes one leg, as desired, even though the predicate's already false at the start.

It's normally better to encapsulate more of the looping logic into your generator (or other iterator) -- for example, if you often have cases where one variable increases, one decreases, and you need a do/while loop comparing them, you could code:

def incandec(i, j, delta=1):
  while True:
    yield i, j
    if j <= i: break
    i+=delta; j-=delta

which you can use like:

for i, j in incandec(i=7, j=3):
  print i, j

It's up to you how much loop-related logic you want to put inside your generator (or other iterator) and how much you want to have outside of it (just like for any other use of a function, class, or other mechanism you can use to refactor code out of your main stream of execution), but, generally speaking, I like to see the generator used in a for loop that has little (ideally none) "loop control logic" (code related to updating state variables for the next loop leg and/or making tests about whether you should be looping again or not).

Well the above answers have give a good explanations to half of the question. For the other half.

Why don't just hide the scroll bar itself. This way it will look more appealing as most of the people ( including me ) hate the scroll bar. You can use this code

::-webkit-scrollbar {
    width: 0px;  /* Remove scrollbar space */
    background: transparent;  /* Optional: just make scrollbar invisible */
}

For me, this js reproduces the same problem that happens with Paola

My solution:

$(document.body).tooltip({selector: '[title]'})
.on('click mouseenter mouseleave','[title]', function(ev) {
    $(this).tooltip('mouseenter' === ev.type? 'show': 'hide');
});

I would advise reading Java puzzlers. It explains inheritance, generics, abstractions, and wildcards in declarations quite well. http://www.javapuzzlers.com/

Change position:absolute to position:fixed;.

Example can be found in this jsFiddle.

the best way (for me) to make it it's the next infrastructure:

<form method="POST">
<input type="submit" formaction="default_url_when_press_enter" style="visibility: hidden; display: none;">
<!-- all your inputs -->
<input><input><input>
<!-- all your inputs -->
<button formaction="action1">Action1</button>
<button formaction="action2">Action2</button>
<input type="submit" value="Default Action">
</form>

with this structure you will send with enter a direction and the infinite possibilities for the rest of buttons.

If you need to do this as part of a script then the best way is to use Java. Assuming the bin directory is in your path (in most cases), you can use the command line:

jar xf test.zip

If Java is not on your path, reference it directly:

C:\Java\jdk1.6.0_03\bin>jar xf test.zip

@Josh Lindsey already answered perfectly fine. But I want to add some information since I often use ssh.

Therefore just change:

git remote add origin [email protected]:/path/to/my_project.git

to:

git remote add origin ssh://[email protected]/path/to/my_project

Note that the colon between domain and path isn't there anymore.

have you tried to remove the timezone awareness?

from http://pytz.sourceforge.net/

naive = dt.replace(tzinfo=None)

may have to add time zone conversion as well.

edit: Please be aware the age of this answer. An answer involving ADDing the timezone info instead of removing it in python 3 is below. https://stackoverflow.com/a/25662061/93380

Use:

window.location.href

As noted in the comments, the line below works, but it is bugged for Firefox.

document.URL

See URL of type DOMString, readonly.

Use the oncontextmenu event.

Here's an example:

<div oncontextmenu="javascript:alert('success!');return false;">
    Lorem Ipsum
</div>

And using event listeners (credit to rampion from a comment in 2011):

el.addEventListener('contextmenu', function(ev) {
    ev.preventDefault();
    alert('success!');
    return false;
}, false);

Don't forget to return false, otherwise the standard context menu will still pop up.

If you are going to use a function you've written rather than javascript:alert("Success!"), remember to return false in BOTH the function AND the oncontextmenu attribute.

Do that like this

db.Users.OrderByDescending(u => u.UserId).FirstOrDefault();

List<T> li = new List<T>();
(li.First().DefaultValue.HasValue) ? string.Format("{0:yyyy/MM/dd}", sender.First().DefaultValue.Value) : string.Empty;

Messing around with the line-height attribute should do the trick. I haven't tested this, so the exact value may not be right, but start with 1.5em, and tweak it in 0.1 increments until it lines up.

.pdf{ line-height:1.5em; }

I use spring boot, so i can simple use:

File file = ResourceUtils.getFile("classpath:myfile.xml");

Considering that you are using OpenCV, the best way to convert between data types is to use normalize function.

img_n = cv2.normalize(src=img, dst=None, alpha=0, beta=255, norm_type=cv2.NORM_MINMAX, dtype=cv2.CV_8U)

However, if you don't want to use OpenCV, you can do this in numpy

def convert(img, target_type_min, target_type_max, target_type):
    imin = img.min()
    imax = img.max()

    a = (target_type_max - target_type_min) / (imax - imin)
    b = target_type_max - a * imax
    new_img = (a * img + b).astype(target_type)
    return new_img

And then use it like this

imgu8 = convert(img16u, 0, 255, np.uint8)

This is based on the answer that I found on crossvalidated board in comments under this solution https://stats.stackexchange.com/a/70808/277040

@JSideris, sample code for getting insertedId.

db.collection(COLLECTION).insertOne(data, (err, result) => {
    if (err) 
      return err;
    else 
      return result.insertedId;
  });

There are some problems when logical vector contains NA values.
See for example:

z <- c(TRUE, FALSE, NA)
sum(z) # gives you NA
table(z)["TRUE"] # gives you 1
length(z[z == TRUE]) # f3lix answer, gives you 2 (because NA indexing returns values)

So I think the safest is to use na.rm = TRUE:

sum(z, na.rm = TRUE) # best way to count TRUE values

(which gives 1). I think that table solution is less efficient (look at the code of table function).

Also, you should be careful with the "table" solution, in case there are no TRUE values in the logical vector. Suppose z <- c(NA, FALSE, NA) or simply z <- c(FALSE, FALSE), then table(z)["TRUE"] gives you NA for both cases.

The following works in Firefox and Opera (sorry, I do not have access to other browsers at the moment):

<div class="form-field">
    <input id="option1" type="radio" name="opt"/>
    <label for="option1">Option 1</label>
</div>

The CSS:

.form-field * {
    vertical-align: middle;
}

As of Spark 2.0.0, you can do the following.

Case Class

Let's define a Person case class:

scala> case class Person(id: Int, name: String)
defined class Person

Import spark SparkSession implicit Encoders:

scala> import spark.implicits._
import spark.implicits._

And use SparkSession to create an empty Dataset[Person]:

scala> spark.emptyDataset[Person]
res0: org.apache.spark.sql.Dataset[Person] = [id: int, name: string]

Schema DSL

You could also use a Schema "DSL" (see Support functions for DataFrames in org.apache.spark.sql.ColumnName).

scala> val id = $"id".int
id: org.apache.spark.sql.types.StructField = StructField(id,IntegerType,true)

scala> val name = $"name".string
name: org.apache.spark.sql.types.StructField = StructField(name,StringType,true)

scala> import org.apache.spark.sql.types.StructType
import org.apache.spark.sql.types.StructType

scala> val mySchema = StructType(id :: name :: Nil)
mySchema: org.apache.spark.sql.types.StructType = StructType(StructField(id,IntegerType,true), StructField(name,StringType,true))

scala> import org.apache.spark.sql.Row
import org.apache.spark.sql.Row

scala> val emptyDF = spark.createDataFrame(sc.emptyRDD[Row], mySchema)
emptyDF: org.apache.spark.sql.DataFrame = [id: int, name: string]

scala> emptyDF.printSchema
root
 |-- id: integer (nullable = true)
 |-- name: string (nullable = true)

One of the best resources I found was using let's encrypt, you do not need ELB nor cloudfront for your EC2 instance to have HTTPS, just follow the following simple instructions: let's encrypt Login to your server and follow the steps in the link.

It is also important as mentioned by others that you have port 443 opened by editing your security groups

You can view your certificate or any other website's by changing the site name in this link

Please do not forget that it is only valid for 90 days

More generally, under most circumstances, underscore functions that take a list and argument as the first two arguments, provide access to the list index as the next to last argument to the iterator. This is an important distinction when it comes to the two underscore functions, _.reduce and _.reduceRight, that take 'memo' as their third argument -- in the case of these two the index will not be the second argument, but the third:

var destination = (function() {
    var fields = ['_333st', 'offroad', 'fbi'];
    return _.reduce(waybillInfo.destination.split(','), function(destination, segment, index) {
        destination[fields[index]] = segment;
        return destination;
    }, {});
})();

console.log(destination);            
/*
_333st: "NYARFTW  TX"
fbi: "FTWUP"
offroad: "UP"

The following is better of course but not demonstrate my point:
var destination = _.object(['_333st', 'offroad', 'fbi'], waybillInfo.destination.split(','));
*/

So if you wanted you could get the index using underscore itself: _.last(_.initial(arguments)). A possible exception (I haven't tried) is _.map, as it can take an object instead of a list: "If list is a JavaScript object, iterator's arguments will be (value, key, list)." -- see: http://underscorejs.org/#map

Far better way than using a static variable and following OOP

Shared Preferences can be used to share variables with other activities and services from one application

    public class example extends Activity {

    @Override
    protected void onStart() {
        super.onStart();

        // Store our shared preference
        SharedPreferences sp = getSharedPreferences("OURINFO", MODE_PRIVATE);
        Editor ed = sp.edit();
        ed.putBoolean("active", true);
        ed.commit();
    }

    @Override
    protected void onStop() {
        super.onStop();

        // Store our shared preference
        SharedPreferences sp = getSharedPreferences("OURINFO", MODE_PRIVATE);
        Editor ed = sp.edit();
        ed.putBoolean("active", false);
        ed.commit();

    }
}

Use shared preferences. It has the most reliable state information, less application switch/destroy issues, saves us to ask for yet another permission and it gives us more control to decide when our activity is actually the topmost. see details here abd here also

The struct module mimics C structures. It takes more CPU cycles for a processor to read a 16-bit word on an odd address or a 32-bit dword on an address not divisible by 4, so structures add "pad bytes" to make structure members fall on natural boundaries. Consider:

struct {                   11
    char a;      012345678901
    short b;     ------------
    char c;      axbbcxxxdddd
    int d;
};

This structure will occupy 12 bytes of memory (x being pad bytes).

Python works similarly (see the struct documentation):

>>> import struct
>>> struct.pack('BHBL',1,2,3,4)
'\x01\x00\x02\x00\x03\x00\x00\x00\x04\x00\x00\x00'
>>> struct.calcsize('BHBL')
12

Compilers usually have a way of eliminating padding. In Python, any of =<>! will eliminate padding:

>>> struct.calcsize('=BHBL')
8
>>> struct.pack('=BHBL',1,2,3,4)
'\x01\x02\x00\x03\x04\x00\x00\x00'

Beware of letting struct handle padding. In C, these structures:

struct A {       struct B {
    short a;         int a;
    char b;          char b;
};               };

are typically 4 and 8 bytes, respectively. The padding occurs at the end of the structure in case the structures are used in an array. This keeps the 'a' members aligned on correct boundaries for structures later in the array. Python's struct module does not pad at the end:

>>> struct.pack('LB',1,2)
'\x01\x00\x00\x00\x02'
>>> struct.pack('LBLB',1,2,3,4)
'\x01\x00\x00\x00\x02\x00\x00\x00\x03\x00\x00\x00\x04'

This is an old post but maybe this could help people to complete the CORS problem. To complete the basic authorization problem you should avoid authorization for OPTIONS requests in your server. This is an Apache configuration example. Just add something like this in your VirtualHost or Location.

<LimitExcept OPTIONS>
    AuthType Basic
    AuthName <AUTH_NAME>
    Require valid-user
    AuthUserFile <FILE_PATH>
</LimitExcept>

I would do something like this

DEMO in JsBin: http://jsbin.com/ofiqur/1/

  <a href="#" id="showmenu">Click Here</a>
  <div class="menu">
    <ul>
      <li><a href="#">Button 1</a></li>
      <li><a href="#">Button 2</a></li>
      <li><a href="#">Button 3</a></li>
    </ul>
  </div>

and in jQuery as simple as

var min = "-100px", // remember to set in css the same value
    max = "0px";

$(function() {
  $("#showmenu").click(function() {

    if($(".menu").css("marginLeft") == min) // is it left?
      $(".menu").animate({ marginLeft: max }); // move right
    else
      $(".menu").animate({ marginLeft: min }); // move left

  });
});

Executive summary / TL;DR:
Try doing a find & replace of "=" with "=". Yes, replace the equals sign with itself. For my scenario, it forced everything to update.

Background:
I frequently make formulas across multiple columns then concatenate them together. After doing such, I'll copy & paste them as values to extract my created formula. After this process, they're typically stuck displaying a formula, and not displaying a value, unless I enter the cell and press Enter. Pressing F2 & Enter repeatedly is not fun.

As Karthik mentioned, dct.keys() will work but it will return all the keys in dict_keys type not in list type. So if you want all the keys in a list, then list(dct.keys()) will work.

With the help of Jackson library, I was able to find all class properties of type String/integer/double, and respective values in a Map class. (without using reflections api!)

TestClass testObject = new TestClass();
com.fasterxml.jackson.databind.ObjectMapper m = new com.fasterxml.jackson.databind.ObjectMapper();

Map<String,Object> props = m.convertValue(testObject, Map.class);

for(Map.Entry<String, Object> entry : props.entrySet()){
    if(entry.getValue() instanceof String || entry.getValue() instanceof Integer || entry.getValue() instanceof Double){
        System.out.println(entry.getKey() + "-->" + entry.getValue());
    }
}

You can follow this approach :

• Connect to remote machine using Expect Script. If your machine doesn't support expect you can download the same. Writing Expect script is very easy (google to get help on this)
• Put all the action which needs to be performed on remote server in a shell script.
• Invoke remote shell script from expect script once login is successful.

One way is to use the jQuery offset method to translate the event.pageX and event.pageY coordinates from the event into a mouse position relative to the parent. Here's an example for future reference:

$("#something").click(function(e){
   var parentOffset = $(this).parent().offset(); 
   //or $(this).offset(); if you really just want the current element's offset
   var relX = e.pageX - parentOffset.left;
   var relY = e.pageY - parentOffset.top;
});

*Using Robot class you can do this, Try following code:

Actions action = new Actions(driver);
action.contextClick(WebElement).build().perform();
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_DOWN);
robot.keyRelease(KeyEvent.VK_DOWN);
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);

[UPDATE]

CAUTION: Your Browser should always be in focus i.e. running in foreground while performing Robot Actions, other-wise any other application in foreground will receive the actions.

Use .unshift() to add to the beginning of an array.

TheArray.unshift(TheNewObject);

See MDN for doc on unshift() and here for doc on other array methods.

FYI, just like there's .push() and .pop() for the end of the array, there's .shift() and .unshift() for the beginning of the array.

There is a difference between loading a file and downloading a file. The following html code loads a file:

<a href="http://www.fbi.gov/top-secret.pdf">loading on the same tab</a>

After clicking on this link, your current tab will be replaced with the pdf-file that can then be downloaded. On right-clicking on this link, you can choose the menu item save link as for downloading the file directly. If you wish to obtain a save as dialog on clicking on such a link, you might want to take the following code:

<a href="http://www.fbi.gov/top-secret.pdf?download=1">save as...</a>

Your browser will download this file immediately if you choose to use a download directory in your options. Otherwise, your browser will be offering a save as-dialog.

You can also choose a button for downloading:

<button type="submit" onclick="window.open('http://www.fbi.gov/top-secret.pdf?download=1')">
    save as...
</button>

If you wish to load the link on a new tab, you take

<a href="http://www.fbi.gov/top-secret.pdf" target="_blank">loading on a new tab</a>

A form element does not heed the directive ?download=1. It only heeds the directive target="_blank":

<form method="get" action="http://www.fbi.gov/top-secret.pdf" target="_blank">
    <button type="submit">loading on a new tab</button>
</form>

Using URL:

url = new URL(window.location.href);

if (url.searchParams.get('test')) {

}

EDIT: if you're sad about compatibility, I'd highly suggest https://github.com/medialize/URI.js/.

Your keystore will be in your JAVA_HOME---> JRE -->lib---> security--> cacerts. You need to check where your JAVA_HOME is configured, possibly one of these places,

1. Computer--->Advanced --> Environment variables---> JAVA_HOME

2. Your server startup batch files.

In your import command -keystore cacerts (give full path to the above JRE here instead of just saying cacerts).

Adding max-width: 100%; to the img tag works for me.

For Spring Boot, the accepted answer will overwrite duplicate properties with lower priority ones. This solution will collect the properties into a SortedMap and take only the highest priority duplicate properties.

final SortedMap<String, String> sortedMap = new TreeMap<>();
for (final PropertySource<?> propertySource : env.getPropertySources()) {
    if (!(propertySource instanceof EnumerablePropertySource))
        continue;
    for (final String name : ((EnumerablePropertySource<?>) propertySource).getPropertyNames())
        sortedMap.computeIfAbsent(name, propertySource::getProperty);
}

I believe you need to make sure that all the container div tags above the 100% height div also has 100% height set on them including the body tag and html.

The following code will list them out:

adb shell dumpsys package <packagename>

This:

git log --oneline --grep='Searched phrase'

or this:

git log --oneline --name-status --grep='Searched phrase'

commands work best for me.

If you are working with Android's MediaStore database, here is how to store an image and then display it after it is saved.

on button click write this

 Intent in = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            in.putExtra("crop", "true");
            in.putExtra("outputX", 100);
            in.putExtra("outputY", 100);
            in.putExtra("scale", true);
            in.putExtra("return-data", true);

            startActivityForResult(in, 1);

then do this in your activity

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1 && resultCode == RESULT_OK && data != null) {

            Bitmap bmp = (Bitmap) data.getExtras().get("data");

            img.setImageBitmap(bmp);
            btnadd.requestFocus();

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
            byte[] b = baos.toByteArray();
            String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);

            byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
            Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
                    bytarray.length);

        }

    }

I do agree with you, Hamlin. When you are transfer data using SSIS or when want to replicate data, it seems quite necessary to temporarily disable or drop foreign key constraints and then re-enable or recreate them. In these cases, referential integrity is not an issue, because it is already maintained in the source database. Therefore, you can rest assured regarding this matter.

This is same as the previous solution but I have defined the function in df.apply itself:

df['Value'] = df.apply(lambda row: row['a']%row['c'], axis=1)

I haven't checked this lately, but I know in the past with Oracle that the JDBC driver would reserve a chunk of memory during query execution to hold the result set coming back. The size of the memory chunk is dependent on the column definitions and the fetch size. So the length of the varchar2 columns affects how much memory is reserved. This caused serious performance issues for me years ago as we always used varchar2(4000) (the max at the time) and garbage collection was much less efficient than it is today.

If it is a Spring App, just paste the code in config class

        @Bean
        public ObjectMapper getJacksonObjectMapper() {
            ObjectMapper objectMapper = new ObjectMapper();
            objectMapper.findAndRegisterModules();
            objectMapper.configure(
                    com.fasterxml.jackson.databind.SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
            objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
            objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
            return objectMapper;
        }
  

This will give you what you want in a pop-up.

for(var i = 0; i < users.Count; i++){
   alert(users[i].id);  
}

Answer for people from Google

In Eclipse you can manually download javadoc and sources.

To do that, right click on the project and use

• Maven -> Download JavaDoc
• Maven -> Download Sources

There are many way you can do this. Those are given bellow:

Suppose your original number is given bellow: double number = 2354548.235;

Using NumberFormat and Rounding mode

NumberFormat nf = DecimalFormat.getInstance(Locale.ENGLISH);
    DecimalFormat decimalFormatter = (DecimalFormat) nf;
    decimalFormatter.applyPattern("#,###,###.##");
    decimalFormatter.setRoundingMode(RoundingMode.CEILING);

    String fString = decimalFormatter.format(number);
    System.out.println(fString);

Using String formatter

System.out.println(String.format("%1$,.2f", number));

In all cases the output will be: 2354548.24

Note:

During rounding you can add RoundingMode in your formatter. Here are some Rounding mode given bellow:

    decimalFormat.setRoundingMode(RoundingMode.CEILING);
    decimalFormat.setRoundingMode(RoundingMode.FLOOR);
    decimalFormat.setRoundingMode(RoundingMode.HALF_DOWN);
    decimalFormat.setRoundingMode(RoundingMode.HALF_UP);
    decimalFormat.setRoundingMode(RoundingMode.UP);

Here are the imports:

import java.math.BigDecimal;
import java.math.RoundingMode;
import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.util.Locale;

func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
    scrollingFinished(scrollView: scrollView)
}

func scrollViewDidEndDragging(_ scrollView: UIScrollView, willDecelerate decelerate: Bool) {
    if decelerate {
        //didEndDecelerating will be called for sure
        return
    }
    scrollingFinished(scrollView: scrollView)        
}

func scrollingFinished(scrollView: UIScrollView) {
   // Your code
}

I was facing the same issue in my Angular application. I was using RocketChat REST API in my application and I was trying to use the rooms.createDiscussion, but as an error as below.

ERROR Error: Uncaught (in promise): HttpErrorResponse: {"headers":{"normalizedNames":{},"lazyUpdate":null},"status":200,"statusText":"OK","url":"myurl/rocketchat/api/v1/rooms.createDiscussion","ok":false,"name":"HttpErrorResponse","message":"Http failure during parsing for myrul/rocketchat/api/v1/rooms.createDiscussion","error":{"error":{},"text":"

I have tried couple of things like changing the responseType: 'text' but none of them worked. At the end I was able to find the issue was with my RocketChat installation. As mentioned in the RocketChat change log the API rooms.createDiscussion is been introduced in the version 1.0.0 unfortunately I was using a lower version.

My suggestion is to check the REST API is working fine or not before you spend time to fix the error in your Angular code. I used curl command to check that.

curl -H "X-Auth-Token: token" -H "X-User-Id: userid" -H "Content-Type: application/json" myurl/rocketchat/api/v1/rooms.createDiscussion -d '{ "prid": "GENERAL", "t_name": "Discussion Name"}'

There as well I was getting an invalid HTML as a response.

<!DOCTYPE html>
<html>
<head>
<meta name="referrer" content="origin-when-crossorigin">
<script>/* eslint-disable */

'use strict';
(function() {
        var debounce = function debounce(func, wait, immediate) {

Instead of a valid JSON response as follows.

{
    "discussion": {
        "rid": "cgk88DHLHexwMaFWh",
        "name": "WJNEAM7W45wRYitHo",
        "fname": "Discussion Name",
        "t": "p",
        "msgs": 0,
        "usersCount": 0,
        "u": {
            "_id": "rocketchat.internal.admin.test",
            "username": "rocketchat.internal.admin.test"
        },
        "topic": "general",
        "prid": "GENERAL",
        "ts": "2019-04-03T01:35:32.271Z",
        "ro": false,
        "sysMes": true,
        "default": false,
        "_updatedAt": "2019-04-03T01:35:32.280Z",
        "_id": "cgk88DHLHexwMaFWh"
    },
    "success": true
}

So after updating to the latest RocketChat I was able to use the mentioned REST API.

You can solve it in two ways.

1. Make sure you put the CDN into the end of html page and place your own script after that. Example:

    <body>
      <div id="main">
        <div id="mainActivity" v-component="{{currentActivity}}" class="activity"></div>

where you need to put same javascript code you wrote in any other JavaScript file or in html file.

2. Use window.onload function in your JavaScript file.

The problem is on this line:

oShell.run "cmd.exe /C copy "S:Claims\Sound.wav" "C:\WINDOWS\Media\Sound.wav"

Your first quote next to "S:Claims" ends the string; you need to escape the quotes around your files with a second quote, like this:

oShell.run "cmd.exe /C copy ""S:\Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

You also have a typo in S:Claims\Sound.wav, should be S:\Claims\Sound.wav.

I also assume the apostrophe before Dim oShell and after Set oShell = Nothing are typos as well.

CSS:

html,body {
    background: url(images/bg.jpg) no-repeat center center fixed;
    -webkit-background-size: cover; /* For WebKit*/
    -moz-background-size: cover;    /* Mozilla*/
    -o-background-size: cover;      /* Opera*/
    background-size: cover;         /* Generic*/
}

The best way to handle this (with ease and no additional software) is with Excel - but using Powerpivot (which has MSFT Power Query embedded). Simply create a new Power Pivot data model that attaches to your large csv or text file. You will then be able to import multi-million rows into memory using the embedded X-Velocity (in-memory compression) engine. The Excel sheet limit is not applicable - as the X-Velocity engine puts everything up in RAM in compressed form. I have loaded 15 million rows and filtered at will using this technique. Hope this helps someone... - Jaycee

Server side put this on top of .php:

 header('Access-Control-Allow-Origin: *');  

You can set specific domain restriction access:

header('Access-Control-Allow-Origin: https://www.example.com')

This is my solution with prepared statements and stored procedure is returning several rows not only one value.

<?php

require 'config.php';
header('Content-type:application/json');
$connection->set_charset('utf8');

$mIds = $_GET['ids'];

$stmt = $connection->prepare("CALL sp_takes_string_returns_table(?)");
$stmt->bind_param("s", $mIds);

$stmt->execute();

$result = $stmt->get_result();
$response = $result->fetch_all(MYSQLI_ASSOC);
echo json_encode($response);

$stmt->close();
$connection->close();

Bounds checked:

 [a[index] for index in (1,2,5,20) if 0 <= index < len(a)]
 # [11, 12, 15] 

It's about the ABI, in order to let both C and C++ application use C interfaces without any issue.

Since C language is very easy, code generation was stable for many years for different compilers, such as GCC, Borland C\C++, MSVC etc.

While C++ becomes more and more popular, a lot things must be added into the new C++ domain (for example finally the Cfront was abandoned at AT&T because C could not cover all the features it needs). Such as template feature, and compilation-time code generation, from the past, the different compiler vendors actually did the actual implementation of C++ compiler and linker separately, the actual ABIs are not compatible at all to the C++ program at different platforms.

People might still like to implement the actual program in C++ but still keep the old C interface and ABI as usual, the header file has to declare extern "C" {}, it tells the compiler generate compatible/old/simple/easy C ABI for the interface functions if the compiler is C compiler not C++ compiler.

I install the Oracle server and it allows to connect from the local machine with no problem. But from another Maclaptop on my home network, it can't connect using either Sql Developer or Sql Plus. After doing some research, I figured out there is this additional step you have to do:

Use the Oracle net manager. Select the Listener. Add the IP address (in my case it is 192.168.1.12) besides of the 127.0.0.1 or localhost.

This will end up add an entry to the [OracleHome]\product\11.2.0\dbhome_1\network\admin\listener.ora

• restart the listener service. (note: for me I reboot machine once to make it work)

• Use lsnrctl status to verify
  Notice the additional HOST=192.168.1.12 shows up and this is what to make remote connection to work.

You probably didn't fully deactivate the Conda environment - remember, the command you need to use with Conda is conda deactivate (for older versions, use source deactivate). So it may be wise to start a new shell and activate the environment in that before you try. Then deactivate it.

You can use the command

conda env remove -n ENV_NAME

to remove the environment with that name. (--name is equivalent to -n)

Note that you can also place environments anywhere you want using -p /path/to/env instead of -n ENV_NAME when both creating and deleting environments, if you choose. They don't have to live in your conda installation.

UPDATE, 30 Jan 2019: From Conda 4.6 onwards the conda activate command becomes the new official way to activate an environment across all platforms. The changes are described in this Anaconda blog post

I was used to the C# (Sharp) String.Remove method. In Javascript, there is no remove function for string, but there is substr function. You can use the substr function once or twice to remove characters from string. You can make the following function to remove characters at start index to the end of string, just like the c# method first overload String.Remove(int startIndex):

function Remove(str, startIndex) {
    return str.substr(0, startIndex);
}

and/or you also can make the following function to remove characters at start index and count, just like the c# method second overload String.Remove(int startIndex, int count):

function Remove(str, startIndex, count) {
    return str.substr(0, startIndex) + str.substr(startIndex + count);
}

and then you can use these two functions or one of them for your needs!

Example:

alert(Remove("data-123", 0, 5));

Output: 123

The best solution that I've found for such case is

select column_name, data_type||
case
when data_precision is not null and nvl(data_scale,0)>0 then '('||data_precision||','||data_scale||')'
when data_precision is not null and nvl(data_scale,0)=0 then '('||data_precision||')'
when data_precision is null and data_scale is not null then '(*,'||data_scale||')'
when char_length>0 then '('||char_length|| case char_used 
                                                         when 'B' then ' Byte'
                                                         when 'C' then ' Char'
                                                         else null 
                                           end||')'
end||decode(nullable, 'N', ' NOT NULL')
from user_tab_columns
where table_name = 'TABLE_NAME'
and column_name = 'COLUMN_NAME';

@Aaron Stainback, thank you for correction!

// TEST
// 1 Day 6 Hours 50 Minutes 31 Seconds ~ 111031 seconds

$time = 111031; // time duration in seconds

$days = floor($time / (60 * 60 * 24));
$time -= $days * (60 * 60 * 24);

$hours = floor($time / (60 * 60));
$time -= $hours * (60 * 60);

$minutes = floor($time / 60);

Heh, there are some pretty exciting uses of ternary syntax in your question; I like the last one the best...

x = (1 < 2) ? true : false;

The use of ternary here is totally unnecessary - you could simply write

x = (1 < 2);

Likewise, the condition element of a ternary statement is always evaluated as a Boolean value, and therefore you can express:

(IsChecked == true) ? removeItem($this) : addItem($this);

Simply as:

(IsChecked) ? removeItem($this) : addItem($this);

In fact, I would also remove the IsChecked temporary as well which leaves you with:

($this.hasClass("IsChecked")) ? removeItem($this) : addItem($this);

As for whether this is acceptable syntax, it sure is! It's a great way to reduce four lines of code into one without impacting readability. The only word of advice I would give you is to avoid nesting multiple ternary statements on the same line (that way lies madness!)

By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment.

The problem with push command is that you your local and remote repository doesn't match. IF you initialize readme by default when creating new repository from git hub, then, master branch is automatically created. However, when you try to push that has no any branch. you cannot push... So, the best practice is to create repo without default readme initialization.

Consider this: I use it to export 20 typed list by same way:

private void Generate<T>()
{
    T item = (T)Activator.CreateInstance(typeof(T));

    ((T)item as DemomigrItemList).Initialize();

    Type type = ((T)item as DemomigrItemList).AsEnumerable().FirstOrDefault().GetType();
    if (type == null) return;
    if (type != typeof(account)) //account is listitem in List<account>
    {
        ((T)item as DemomigrItemList).CreateCSV(type);
    }
}

I realize this is a very-very-very old thread but I had a thought about this and wanted to know what people thought.

Notes: I was playing around with this and realized that if I just modified the __call() function that you can get even closer to actual enums. The __call() function handles all unknown function calls. So let's say you want to make three enums RED_LIGHT, YELLOW_LIGHT, and GREEN_LIGHT. You can do so now by just doing the following:

$c->RED_LIGHT();
$c->YELLOW_LIGHT();
$c->GREEN_LIGHT();

Once defined all you have to do is to call them again to get the values:

echo $c->RED_LIGHT();
echo $c->YELLOW_LIGHT();
echo $c->GREEN_LIGHT();

and you should get 0, 1, and 2. Have fun! This is also now up on GitHub.

Update: I've made it so both the __get() and __set() functions are now used. These allow you to not have to call a function unless you want to. Instead, now you can just say:

$c->RED_LIGHT;
$c->YELLOW_LIGHT;
$c->GREEN_LIGHT;

For both the creation and getting of the values. Because the variables haven't been defined initially, the __get() function is called (because there isn't a value specified) which sees that the entry in the array hasn't been made. So it makes the entry, assigns it the last value given plus one(+1), increments the last value variable, and returns TRUE. If you set the value:

$c->RED_LIGHT = 85;

Then the __set() function is called and the last value is then set to the new value plus one (+1). So now we have a fairly good way to do enums and they can be created on the fly.

It doesn't work because the list is empty. Try this:

private void button1_Click(object sender, EventArgs e)
{
    List<Button> buttons = new List<Button>();
    for (int i = 0; i < 10; i++)
    {

        buttons.Add(newButton);
        this.Controls.Add(newButton);

The SimpleDateFormat class allows you to parse a String into a java.util.Date object. Once you have the Date object, you can get the milliseconds since the epoch by calling Date.getTime().

The full example:

String myDate = "2014/10/29 18:10:45";
//creates a formatter that parses the date in the given format
SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = sdf.parse(myDate);
long timeInMillis = date.getTime();

Note that this gives you a long and not a double, but I think that's probably what you intended. The documentation for the SimpleDateFormat class has tons on information on how to set it up to parse different formats.

http://formatmysourcecode.blogspot.co.uk/ works fine, you just copy , format, paste back.

Add to your JS:

jQuery(document).ready(function($) {
  $("body").css({
    'padding-top': $(".navbar").outerHeight() + 'px'
  })
});

Start menu → Accessories → right click on "Command prompt". In the menu, click "Run as Administrator" (on Windows XP you can just run it as usual), run netstat -anb, and then look through output for your program.

BTW, Skype by default tries to use ports 80 and 443 for incoming connections.

You can also run netstat -anb >%USERPROFILE%\ports.txt followed by start %USERPROFILE%\ports.txt to open the port and process list in a text editor, where you can search for the information you want.

You can also use PowerShell to parse netstat output and present it in a better way (or process it any way you want):

$proc = @{};
Get-Process | ForEach-Object { $proc.Add($_.Id, $_) };
netstat -aon | Select-String "\s*([^\s]+)\s+([^\s]+):([^\s]+)\s+([^\s]+):([^\s]+)\s+([^\s]+)?\s+([^\s]+)" | ForEach-Object {
    $g = $_.Matches[0].Groups;

Also it does not require elevation to run.

Change your directive definition from app.module to app.directive. Apart from that everything looks fine. Btw, very rarely do you have to inject a service into a directive. If you are injecting a service ( which usually is a data source or model ) into your directive ( which is kind of part of a view ), you are creating a direct coupling between your view and model. You need to separate them out by wiring them together using a controller.

It does work fine. I am not sure what you are doing which is wrong. Here is a plunk of it working.

create a new folder in your android studio parent directory folder. Name it sdk or whatever you want. Select that folder from the drop down list when asked. Thats what solves it for me.

Rob's answer would be the most vendor-agnostic, but if you're using MySQL the safer and correct choise would be the built-in LAST_INSERT_ID() function.

I added a new environment variable ANDROID_HOME and pointed it to the SDK (C:\Program Files (x86)\Android\android-studio\sdk) that is inside the installation directory of Android Studio. (Environment variables are a part of windows; you access them through the advanced computer properties...google it for more info)

For portable code, the macros in inttypes.h may be used. They expand to the correct ones for the platform.

E.g. for 64 bit integer, the macro PRId64 can be used.

int64_t n = 7;
printf("n is %" PRId64 "\n", n);

You could give bluefish a try. Has a bunch of nice features for website work. Syntax files for most every language.

http://bluefish.openoffice.nl/

If on windows give Crimson Editor a try http://www.crimsoneditor.com/ It's been a long while since I ran windows, but iirc, 'official' development has stopped on it, but the community has taken up a fork of it and called it emerald or somesuch. Crimson editor is still very capable as is.

Both bluefish and crimson editor have project management abilities. FTP ablilities, macros etc etc

Use current_url element for Python 2:

print browser.current_url

For Python 3 and later versions of selenium:

print(driver.current_url)

As indicated here, JavaFX is no longer included in openjdk.

So check, if you have <Java SDK root>/jre/lib/ext/jfxrt.jar on your classpath under Project Structure -> SDKs -> 1.x -> Classpath? If not, that could be why. Try adding it and see if that fixes your issue, e.g. on Ubuntu, install then openjfx package with sudo apt-get install openjfx.

You can use attrchange jQuery plugin. The main function of the plugin is to bind a listener function on attribute change of HTML elements.

Code sample:

$("#myDiv").attrchange({
    trackValues: true, // set to true so that the event object is updated with old & new values
    callback: function(evnt) {
        if(evnt.attributeName == "display") { // which attribute you want to watch for changes
            if(evnt.newValue.search(/inline/i) == -1) {

                // your code to execute goes here...
            }
        }
    }
});

What you're trying to do is to monitor the property of attribute in directive. You can watch the property of attribute changes using $observe() as follows:

angular.module('myApp').directive('conversation', function() {
  return {
    restrict: 'E',
    replace: true,
    compile: function(tElement, attr) {
      attr.$observe('typeId', function(data) {
            console.log("Updated data ", data);
      }, true);

    }
  };
});

Keep in mind that I used the 'compile' function in the directive here because you haven't mentioned if you have any models and whether this is performance sensitive.

If you have models, you need to change the 'compile' function to 'link' or use 'controller' and to monitor the property of a model changes, you should use $watch(), and take of the angular {{}} brackets from the property, example:

<conversation style="height:300px" type="convo" type-id="some_prop"></conversation>

And in the directive:

angular.module('myApp').directive('conversation', function() {
  return {
    scope: {
      typeId: '=',
    },
    link: function(scope, elm, attr) {

      scope.$watch('typeId', function(newValue, oldValue) {
          if (newValue !== oldValue) {
            // You actions here
            console.log("I got the new value! ", newValue);
          }
      }, true);

    }
  };
});

In TorpedoQuery it look like this

Entity from = from(Entity.class);
where(from.getCode()).in("Joe", "Bob");
Query<Entity> select = select(from);

You probably should check this. Windows doesn't have that command built in.

In 3.5, Python finally got a matrix multiplication operator. The syntax is a @ b.

I agree with what @fge said, more over. Lets look at example. Consider you have a method:

class A {
    public void foo(OtherClass other) {
        SomeData data = new SomeData("Some inner data");
        other.doSomething(data);
    }
}

Now if you want to check the inner data you can use the captor:

// Create a mock of the OtherClass
OtherClass other = mock(OtherClass.class);

// Run the foo method with the mock
new A().foo(other);

// Capture the argument of the doSomething function
ArgumentCaptor<SomeData> captor = ArgumentCaptor.forClass(SomeData.class);
verify(other, times(1)).doSomething(captor.capture());

// Assert the argument
SomeData actual = captor.getValue();
assertEquals("Some inner data", actual.innerData);

It happens also if your code is expecting Java Mail 1.4 and your jars are Java Mail 1.3. Happened to me when upgraded Pentaho Kettle

You can find more about it in the bundler website (emphasis added below for your convenience):

After developing your application for a while, check in the application together with the Gemfile and Gemfile.lock snapshot. Now, your repository has a record of the exact versions of all of the gems that you used the last time you know for sure that the application worked...

This is important: the Gemfile.lock makes your application a single package of both your own code and the third-party code it ran the last time you know for sure that everything worked. Specifying exact versions of the third-party code you depend on in your Gemfile would not provide the same guarantee, because gems usually declare a range of versions for their dependencies.

Thanks Jan for spaces \s rest there is some good detail in this link:

http://www.jquery4u.com/syntax/jquery-basic-regex-selector-examples/#.UHKS5UIihlI

Hope it fits your need :)

code

 $(function() {

    $("#field").bind("keyup", function(event) {
        var regex = /^[a-zA-Z\s]+$/;
        if (regex.test($("#field").val())) {
            $('.validation').html('valid');
        } else {
            $('.validation').html("FAIL regex");
        }
    });
});?

Just add the object yourself using regedit:

Under HKEY_LOCAL_MACHINE\SOFTWARE\Policies,

• Create new Key, "Google"
• In "Google", create new Key, "Update"
• In "Update" go to that key and create Dword, "AutoUpdateCheckPeriodMinutes" which automatically value set to 0, just double check and change if needed.

All done!

Restart might be needed.

Your session is lost becoz....

I have found a scenario where session is lost - In a asp.net page, for a amount text box field has invalid characters, and followed by a session variable retrieval for other purpose.After posting the invalid number parsing through Convert.ToInt32 or double raises a first chance exception, but error does not show at that line, Instead of that, Session being null because of unhandled exception, shows error at session retrieval, thus deceiving the debugging...

HINT: Test your system to fail it- DESTRUCTIVE.. enter enough junk in unrelated scenarios for ex: after search results shown enter junk in search criteria and goto details of search result... , you would be able to reproduce this machine on your local code base too...:)

Hope it Helps, hydtechie

jQuery's .bind() fires in the order it was bound:

When an event reaches an element, all handlers bound to that event type for the element are fired. If there are multiple handlers registered, they will always execute in the order in which they were bound. After all handlers have executed, the event continues along the normal event propagation path.

Source: http://api.jquery.com/bind/

Because jQuery's other functions (ex. .click()) are shortcuts for .bind('click', handler), I would guess that they are also triggered in the order they are bound.

Use That :

$(selector).trigger("change");

OR

$('#id').trigger("click");

OR

$('.class').trigger(event);

Trigger can be any event that javascript support.. Hope it's easy to understandable to all of You.

A few options I have used:

If XLSX is a must: ExcelPackage is a good start but died off when the developer quit working on it. ExML picked up from there and added a few features. ExML isn't a bad option, I'm still using it in a couple of production websites.

For all of my new projects, though, I'm using NPOI, the .NET port of Apache POI. NPOI 2.0 (Alpha) also supports XLSX.

I think the accepted way is better, but I guess this might work as well

function getElementByClass(&$parentNode, $tagName, $className, $offset = 0) {
    $response = false;

    $childNodeList = $parentNode->getElementsByTagName($tagName);
    $tagCount = 0;
    for ($i = 0; $i < $childNodeList->length; $i++) {
        $temp = $childNodeList->item($i);
        if (stripos($temp->getAttribute('class'), $className) !== false) {
            if ($tagCount == $offset) {
                $response = $temp;
                break;
            }

            $tagCount++;
        }

    }

    return $response;
}

Try this:

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("your url");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("user_name", "Name"));
nameValuePairs.add(new BasicNameValuePair("pass","Password" ));
nameValuePairs.add(new BasicNameValuePair("user_email","email" ));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);

String ret = EntityUtils.toString(response.getEntity());
Log.v("Util response", ret);

You can add as many nameValuePairs as you need. And don't forget to mention the count in the list.

If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY is not "V_ARRAY", then you are using different types; even if they are declared identically (e.g. both are table of number) this will not work.

You're hitting this data type compatibility restriction:

You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.

You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.

Use data type 'MultilineText':

[DataType(DataType.MultilineText)]
public string Text { get; set; }

See ASP.NET MVC3 - textarea with @Html.EditorFor

Maybe you can run this regex first to see if the line is all caps:

^[A-Z \d\W]+$

That will match only if it's a line like THING P1 MUST CONNECT TO X2.

Otherwise, you should be able to pull out the individual uppercase phrases with this:

[A-Z][A-Z\d]+

That should match "P1" and "J236" in The thing P1 must connect to the J236 thing in the Foo position.

Expanding on @ybo's answer - it isn't possible because the instance you have of the base class isn't actually an instance of the derived class. It only knows about the members of the base class, and doesn't know anything about those of the derived class.

The reason that you can cast an instance of the derived class to an instance of the base class is because the derived class actually already is an instance of the base class, since it has those members already. The opposite cannot be said.

You can do this a number of non-DNS ways. The landing page at subdomain.hostone.com can have an HTTP redirect. The webserver at hostone.com can be configured to redirect (easy in Apache, not sure about IIS), etc.

Simple Example:

break leaves the loop.

int m = 0;
for(int n = 0; n < 5; ++n){
  if(n == 2){
    break;
  }
  m++;
}

System.out.printl("m:"+m); // m:2

continue will go back to start loop.

int m = 0;
for(int n = 0; n < 5; ++n){
  if(n == 2){
    continue; // Go back to start and dont execute m++
  }
  m++;
}

System.out.printl("m:"+m); // m:4

if you want the year in a two number format such as 17 rather than 2017, do the following:

DATE=`date +%d-%m-%y`

This will surely help you.

int n[] = {4,6,9,1,7};

    for(int i=n.length;i>=0;i--){
        for(int j=0;j<n.length-1;j++){
            if(n[j] > n[j+1]){
                swapNumbers(j,j+1,n);
            }
        }

    }
    printNumbers(n);
}
private static void swapNumbers(int i, int j, int[] array) {

    int temp;
    temp = array[i];
    array[i] = array[j];
    array[j] = temp;
}

private static void printNumbers(int[] input) {

    for (int i = 0; i < input.length; i++) {
        System.out.print(input[i] + ", ");
    }
    System.out.println("\n");
}

Quite a detailed and technical answers. Just adding a simple definition.

Idempotent = Re-runnable

For example, Create operation in itself is not guaranteed to run without error if executed more than once. But if there is an operation CreateOrUpdate then it states re-runnability (Idempotency).

The best method for setting a socket as non-blocking in C is to use ioctl. An example where an accepted socket is set to non-blocking is following:

long on = 1L;
unsigned int len;
struct sockaddr_storage remoteAddress;
len = sizeof(remoteAddress);
int socket = accept(listenSocket, (struct sockaddr *)&remoteAddress, &len)
if (ioctl(socket, (int)FIONBIO, (char *)&on))
{
    printf("ioctl FIONBIO call failed\n");
}

select to_char(to_date('1/21/2000','mm/dd/yyyy'),'dd-mm-yyyy') from dual

By default, MomentJS parses in local time. If only a date string (with no time) is provided, the time defaults to midnight.

In your code, you create a local date and then convert it to the UTC timezone (in fact, it makes the moment instance switch to UTC mode), so when it is formatted, it is shifted (depending on your local time) forward or backwards.

If the local timezone is UTC+N (N being a positive number), and you parse a date-only string, you will get the previous date.

Here are some examples to illustrate it (my local time offset is UTC+3 during DST):

>>> moment('07-18-2013', 'MM-DD-YYYY').utc().format("YYYY-MM-DD HH:mm")
"2013-07-17 21:00"
>>> moment('07-18-2013 12:00', 'MM-DD-YYYY HH:mm').utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 09:00"
>>> Date()
"Thu Jul 25 2013 14:28:45 GMT+0300 (Jerusalem Daylight Time)"

If you want the date-time string interpreted as UTC, you should be explicit about it:

>>> moment(new Date('07-18-2013 UTC')).utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

or, as Matt Johnson mentions in his answer, you can (and probably should) parse it as a UTC date in the first place using moment.utc() and include the format string as a second argument to prevent ambiguity.

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

To go the other way around and convert a UTC date to a local date, you can use the local() method, as follows:

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').local().format("YYYY-MM-DD HH:mm")
"2013-07-18 03:00"

These lines Worked for me.

string[] lines = File.ReadAllLines(txtProxyListPath.Text);
var options = new ParallelOptions { MaxDegreeOfParallelism = Environment.ProcessorCount * 10 };
Parallel.ForEach(lines , options, (item) =>
{
 //My Stuff
});

It is worth mentioning that there is also: database scoped global temporary tables(currently supported only by Azure SQL Database).

Global temporary tables for SQL Server (initiated with ## table name) are stored in tempdb and shared among all users’ sessions across the whole SQL Server instance.

Azure SQL Database supports global temporary tables that are also stored in tempdb and scoped to the database level. This means that global temporary tables are shared for all users’ sessions within the same Azure SQL Database. User sessions from other databases cannot access global temporary tables.

-- Session A creates a global temp table ##test in Azure SQL Database testdb1
-- and adds 1 row
CREATE TABLE ##test ( a int, b int);
INSERT INTO ##test values (1,1);

-- Session B connects to Azure SQL Database testdb1 
-- and can access table ##test created by session A
SELECT * FROM ##test
---Results
1,1

-- Session C connects to another database in Azure SQL Database testdb2 
-- and wants to access ##test created in testdb1.
-- This select fails due to the database scope for the global temp tables 
SELECT * FROM ##test
---Results
Msg 208, Level 16, State 0, Line 1
Invalid object name '##test'

ALTER DATABASE SCOPED CONFIGURATION

GLOBAL_TEMPORARY_TABLE_AUTODROP = { ON | OFF }

APPLIES TO: Azure SQL Database (feature is in public preview)

Allows setting the auto-drop functionality for global temporary tables. The default is ON, which means that the global temporary tables are automatically dropped when not in use by any session. When set to OFF, global temporary tables need to be explicitly dropped using a DROP TABLE statement or will be automatically dropped on server restart.

With Azure SQL Database single databases and elastic pools, this option can be set in the individual user databases of the SQL Database server. In SQL Server and Azure SQL Database managed instance, this option is set in TempDB and the setting of the individual user databases has no effect.

Everytime the size of the string is undetermined at compile time you have to allocate memory with malloc (or some equiviallent method). In your case you know the size of your strings at compile time (sizeof("something") and sizeof("something else")).

Although not usually a concern, from a security perspective, it is better to use synchronized on a private object, rather than putting it on a method.

Putting it on the method means you are using the lock of the object itself to provide thread safety. With this kind of mechanism, it is possible for a malicious user of your code to also obtain the lock on your object, and hold it forever, effectively blocking other threads. A non-malicious user can effectively do the same thing inadvertently.

If you use the lock of a private data member, you can prevent this, since it is impossible for a malicious user to obtain the lock on your private object.

private final Object lockObject = new Object();

public void getCount() {
    synchronized( lockObject ) {
        ...
    }
}

This technique is mentioned in Bloch's Effective Java (2nd Ed), Item #70

$total=0;
foreach($group as $key=>$value)
{
   echo $key. " = " .$value. "<br>"; 
   $total+= $value;
}
echo $total;

when my divisor has 0 value

if ($divisor == 0) {
    $divisor = 1;
}

My classes contained a main() method yet I was unable to see the Run option. That option was enabled once I marked a folder containing my class files as a source folder:

1. Right click the folder containing your source
2. Select Mark Directory as → Test Source Root

Some of the classes in my folder don't have a main() method, but I still see a Run option for those.

Did find the answer on my own. My problem was, that i use two temporary tables for a join and create the second one out of the first one. But the Index was not copied during creation...

CREATE TEMPORARY TABLE tmpLivecheck (tmpid INTEGER NOT NULL AUTO_INCREMENT, PRIMARY    
KEY(tmpid), INDEX(tmpid))
SELECT * FROM tblLivecheck_copy WHERE tblLivecheck_copy.devId = did;

CREATE TEMPORARY TABLE tmpLiveCheck2 (tmpid INTEGER NOT NULL, PRIMARY KEY(tmpid), 
INDEX(tmpid))  
SELECT * FROM tmpLivecheck;

... solved my problem.

Greetings...

it simple, select columns want to insert primary key and click on Key icon on header and save table

happy coding..,

You can use a bind variable at the SQLPlus level to do this. Of course you have little control over the formatting of the output.

VAR x REFCURSOR;
EXEC GetGrantListByPI(args, :x);
PRINT x;

Some extend functions in third party libraries are more complex than others. Knockout.js for instance contains a minimally simple one that doesn't have some of the checks that jQuery's does:

function extend(target, source) {
    if (source) {
        for(var prop in source) {
            if(source.hasOwnProperty(prop)) {
                target[prop] = source[prop];
            }
        }
    }
    return target;
}

If you don't want a click function use Jquery change function

$('#radio_button :checked').live('change',function(){
alert('Something is checked.');
});

This should be the answer that you are looking for. if you are using Jquery version above 1.9.1 try to use on as live function had been deprecated.

Using tidyr package, this can be easily handled in 1 function call.

data <- data.frame('a' = 1:3, 
                   'b' = c('a','b','c'), 
                   'c' = c('d', 'e', 'f'), 
                   'd' = c('g', 'h', 'i'))

tidyr::unite_(data, paste(colnames(data)[-1], collapse="_"), colnames(data)[-1])

  a b_c_d
1 1 a_d_g
2 2 b_e_h
3 3 c_f_i

Edit: Exclude first column, everything else gets pasted.

# tidyr_0.6.3

unite(data, newCol, -a) 
# or by column index unite(data, newCol, -1)

#   a newCol
# 1 1  a_d_g
# 2 2  b_e_h
# 3 3  c_f_i

Have you considered using Fetch Injection? I rolled an open source library called fetch-inject to handle cases like these. Here's what your loader might look like using the lib:

fetcInject([
  'js/jquery-1.6.2.min.js',
  'js/marquee.js',
  'css/marquee.css',
  'css/custom-theme/jquery-ui-1.8.16.custom.css',
  'css/main.css'
]).then(() => {
  'js/jquery-ui-1.8.16.custom.min.js',
  'js/farinspace/jquery.imgpreload.min.js'
})

For backwards compatibility leverage feature detection and fall-back to XHR Injection or Script DOM Elements, or simply inline the tags into the page using document.write.

This will remove any number of blank lines

CTRL + H to replace

I've been swearing at this for a while. Zoom is definitely not the solutions, it works in chrome, it works partially in IE but moves the entire html div, firefox doesnt do a thing.

My solution that worked for me was using both a scaling and a translation, and also adding the original height and weight and then setting the height and weight of the div itself:

#miniPreview {
transform: translate(-710px, -1000px) rotate(0rad) skewX(0rad) scale(0.3, 0.3);
transform-origin: 1010px 1429px 0px;
width: 337px;
height: 476px;

Obviously change these to your own needs. It gave me the same result in all browsers.

Here was my solution:

Markup:

<div id="name" disabled="disabled">

Javascript:

document.getElementById("name").disabled = true;

This the best solution for my applications - hope this helps!

Instead of downloading curl, down libcurl.

curl is just the application, libcurl is what you need for your C++ program

Here lies your problem:

private void fillTextView (int id, String text) {
    TextView tv = (TextView) findViewById(id);
    tv.setText(text); // tv is null
}

--> (TextView) findViewById(id); // returns null But from your code, I can't find why this method returns null. Try to track down, what id you give as a parameter and if this view with the specified id exists.

The error message is very clear and even tells you at what method. From the documentation:

public final View findViewById (int id)
    Look for a child view with the given id. If this view has the given id, return this view.
    Parameters
        id  The id to search for.
    Returns
        The view that has the given id in the hierarchy or null

http://developer.android.com/reference/android/view/View.html#findViewById%28int%29

In other words: You have no view with the id you give as a parameter.

Here is one way to test which YAML implementation the user has selected on the virtualenv (or the system) and then define load_yaml_file appropriately:

load_yaml_file = None

if not load_yaml_file:
    try:
        import yaml
        load_yaml_file = lambda fn: yaml.load(open(fn))
    except:
        pass

Demonstrate your mastery of Python by using pip.
Please research the latest pip-based install steps for python-yaml.
Usually something like this works:
   apt-get install epel-release
   apt-get install python-pip
   apt-get install libyaml-cpp-dev
   python2.7 /usr/bin/pip install pyyaml
Notes:
Non-base library (yaml) should never be installed outside a virtualenv.
"pip install" is permanent:

Beware when using pip within an aptitude or RPM script.
  Pip might not play by all the rules.
  Your installation may be permanent.
Ruby is 7X faster at loading large YAML files.
pip could ruin your life.

If you are working for a Fortune 500 company, your choices are
1. Ask for either the "ruby" package or the "python-yaml"
package. Asking for Ruby is more likely to get a fast answer.
2. Work in a VM. I highly recommend Vagrant for setting it up.
