You're running the code before the DOM is loaded.

Try this:

Live example:

http://jsfiddle.net/FvMYz/

$(function() {    // Makes sure the code contained doesn't run until
                  //     all the DOM elements have loaded

    $('#colorselector').change(function(){
        $('.colors').hide();
        $('#' + $(this).val()).show();
    });

});

The better solutions, when possible are:

• Replicate your data (using log-replication) to a reporting database.
• Use SAN snapshots and mount a consistent version of the DB
• Use a database which has a better fundamental transaction isolation level

The SNAPSHOT transaction isolation level was created because MS was losing sales to Oracle. Oracle uses undo/redo logs to avoid this problem. Postgres uses MVCC. In the future MS's Heckaton will use MVCC, but that's years away from being production ready.

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

An alternative way of sending a large number of repeating characters to a text field (for instance to test the maximum number of characters the field will allow) is to type a few characters and then repeatedly copy and paste them:

inputField.sendKeys('0123456789');
for(int i = 0; i < 100; i++) {
    inputField.sendKeys(Key.chord(Key.CONTROL, 'a'));
    inputField.sendKeys(Key.chord(Key.CONTROL, 'c'));
    for(int i = 0; i < 10; i++) {
        inputField.sendKeys(Key.chord(Key.CONTROL, 'v'));
    }
}

Unfortunately pressing CTRL doesn't seem to work for IE unless REQUIRE_WINDOW_FOCUS is enabled (which can cause other issues), but it works fine for Firefox and Chrome.

Use .*, and make sure you are using your implementations' equivalent of single-line so you will match on line endings.

There is a great explanation here -> http://www.regular-expressions.info/dot.html

Meld and KDiff are two of the most popular.

A simpler way, if you are using .NET 3.5, is to use XDocument and XmlSchemaSet validation.

XmlSchemaSet schemas = new XmlSchemaSet();
schemas.Add(schemaNamespace, schemaFileName);

XDocument doc = XDocument.Load(filename);
string msg = "";
doc.Validate(schemas, (o, e) => {
    msg += e.Message + Environment.NewLine;
});
Console.WriteLine(msg == "" ? "Document is valid" : "Document invalid: " + msg);

See the MSDN documentation for more assistance.

Change return false; to return true; in longClickListener

You long click the button, if it returns true then it does the work. If it returns false then it does it's work and also calls the short click and then the onClick also works.

Define the path of the Visual Studio in your ~/.bash_profile as follow

export PATH="$PATH:/Applications/Visual Studio Code.app/Contents/Resources/app/bin"

Disclaimer

There is a way to achieve this which is quite simple, but I wouldn't suggest it is a good approach for an app you are going to let other people see. But if you had some developer need to show the console and windows forms at the same time, it can be done quite easily.

This method also supports showing only the Console window, but does not support showing only the Windows Form - i.e. the Console will always be shown. You can only interact (i.e. receive data - Console.ReadLine(), Console.Read()) with the console window if you do not show the windows forms; output to Console - Console.WriteLine() - works in both modes.

This is provided as is; no guarantees this won't do something horrible later on, but it does work.

Project steps

Start from a standard Console Application.

Mark the Main method as [STAThread]

Add a reference in your project to System.Windows.Forms

Add a Windows Form to your project.

Add the standard Windows start code to your Main method:

End Result

You will have an application that shows the Console and optionally windows forms.

Sample Code

Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace ConsoleApplication9 {
    class Program {

        [STAThread]
        static void Main(string[] args) {

            if (args.Length > 0 && args[0] == "console") {
                Console.WriteLine("Hello world!");
                Console.ReadLine();
            }
            else {
                Application.EnableVisualStyles(); 
                Application.SetCompatibleTextRenderingDefault(false); 
                Application.Run(new Form1());
            }
        }
    }
}

Form1.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace ConsoleApplication9 {
    public partial class Form1 : Form {
        public Form1() {
            InitializeComponent();
        }

        private void Form1_Click(object sender, EventArgs e) {
            Console.WriteLine("Clicked");
        }
    }
}

As far as you're concerned once you've "pulled out" the contents with something like .html() it's just a string. You can test that with

<html> 
  <head>
    <title>runthis</title>
    <script type="text/javascript" language="javascript" src="jquery-1.3.2.js"></script>
    <script type="text/javascript">
        $(document).ready( function() {
            var x = $("#foo").html();
            alert( typeof(x) );
        });
    </script>
    </head>
    <body>
        <div id="foo"><table><tr><td>x</td></tr></table><span>xyz</span></div>
    </body>
</html>

The alert text is string. As long as you don't pass it to a parser there's no magic about it, it's a string like any other string.
There's nothing that hinders you from using .post() to send this string back to the server.

edit: Don't pass a string as the parameter data to .post() but an object, like

var data = {
  id: currid,
  html: div_html
};
$.post("http://...", data, ...);

jquery will handle the encoding of the parameters.
If you (for whatever reason) want to keep your string you have to encode the values with something like escape().

var data = 'id='+ escape(currid) +'&html='+ escape(div_html);

You can add all pages with this code:

JS code:

 /* Top btn */
    $(window).scroll(function() {
        if ($(this).scrollTop()) {
            $('#toTop').fadeIn();
        } else {
            $('#toTop').fadeOut();
        }
    });
    var top_btn_html="<topbtn id='toTop' onclick='gotoTop()'>&#8593;</topbtn>";
    $('document').ready(function(){
        $("body").append(top_btn_html);
    });
    function gotoTop(){
        $("html, body").animate({scrollTop: 0}, 500);    
    }
    /* Top btn */

CSS CODE

/*Scrool top btn*/
#toTop{
    position: fixed;
    z-index: 10000;
    opacity: 0.5;
    right: 5px;
    bottom: 10px;
    background-color: #ccc;
    border: 1px solid black;
    width: 40px;
    height: 40px;
    border-radius: 20px;
    color: black;
    font-size: 22px;
    font-weight: bolder;
    text-align: center;
    vertical-align: middle;
}

First you check your user agent OS Linux or windows or another. Then Your OS Windows Then this code use:

public function win_os(){ 
    ob_start();
    system('ipconfig-a');
    $mycom=ob_get_contents(); // Capture the output into a variable
    ob_clean(); // Clean (erase) the output buffer
    $findme = "Physical";
    $pmac = strpos($mycom, $findme); // Find the position of Physical text
    $mac=substr($mycom,($pmac+36),17); // Get Physical Address

    return $mac;
   }

And your OS Linux Ubuntu or Linux then this code use:

public function unix_os(){
    ob_start();
    system('ifconfig -a');
    $mycom = ob_get_contents(); // Capture the output into a variable
    ob_clean(); // Clean (erase) the output buffer
    $findme = "Physical";
    //Find the position of Physical text 
    $pmac = strpos($mycom, $findme); 
    $mac = substr($mycom, ($pmac + 37), 18);

    return $mac;
    }

This code may be work OS X.

Just right click on the Project Solution A window pops up. Expand the common Properties. Select Start Up Project

In there on right hand side Select radio button with Single Startup Project Select your Project in there and apply.

That's it. Now save and build your project. Run the project to see the output.

The following code will list them out:

adb shell dumpsys package <packagename>

Note: this answer is only valid for git v1.8 and older.

Most of this has been said in the other answers and comments, but here's a concise explanation:

• git fetch fetches all branch heads (or all specified by the remote.fetch config option), all commits necessary for them, and all tags which are reachable from these branches. In most cases, all tags are reachable in this way.
• git fetch --tags fetches all tags, all commits necessary for them. It will not update branch heads, even if they are reachable from the tags which were fetched.

Summary: If you really want to be totally up to date, using only fetch, you must do both.

It's also not "twice as slow" unless you mean in terms of typing on the command-line, in which case aliases solve your problem. There is essentially no overhead in making the two requests, since they are asking for different information.

I have faced the same problem a week ago. The problem is with the time zone setting. Specify in other formats like mm/dd/yyyy (usually works).

Specifying the date as 30/12/2013 resulted in the error for me. However, specifying it as mm/dd/yyyy format worked.

If you need to convert your input the you can try looking into the CONVERT method. Syntax is

CONVERT(VARCHAR,@your_date_Value,103)

CONVERT(VARCHAR, '12/30/2013', 103)

The finishing 103 is the datetime format.

Refer this link for conversion formats and further reading. https://www.w3schools.com/sql/func_sqlserver_convert.asp

See Math.Pow. The function takes a value and raises it to a specified power:

Math.Pow(100.00, 3.00); // 100.00 ^ 3.00

Most of the time you want to get the IDs of the products in the cart so that you can make some comparison with some other logic - example settings in the backend.

In such a case you can extend the answer from @Rohil_PHPBeginner and return the IDs in an array as follows :

<?php 

    function njengah_get_ids_of_products_in_cart(){
    
            global $woocommerce;
    
            $productsInCart = array(); 
            
            $items = $woocommerce->cart->get_cart(); 
            
            foreach($items as $item => $values) { 
            
                $_product =  wc_get_product( $values['data']->get_id()); 
                
               /* Display Cart Items Content  */ 
               
                echo "<b>".$_product->get_title().'</b>  <br> Quantity: '.$values['quantity'].'<br>'; 
                $price = get_post_meta($values['product_id'] , '_price', true);
                echo "  Price: ".$price."<br>";
                
                /**Get IDs and in put them in an  Array**/ 
                
                $productsInCart_Ids[] =  $_product->get_id();
            }
           
           /** To Display **/ 
              
           print_r($productsInCart_Ids);
           
           /**To Return for Comparision with some Other Logic**/ 
           
           return $productsInCart_Ids; 
    
        }

You lookup the value of the data with findData() and then use setCurrentIndex()

QComboBox* combo = new QComboBox;
combo->addItem("100",100.0);    // 2nd parameter can be any Qt type
combo->addItem .....

float value=100.0;
int index = combo->findData(value);
if ( index != -1 ) { // -1 for not found
   combo->setCurrentIndex(index);
}

From now you can use In App Rating feature by Google.

Here is Kotlin/Java integration official guide

The Google Play In-App Review API lets you prompt users to submit Play Store ratings and reviews without the inconvenience of leaving your app or game.

Generally, the in-app review flow (see figure 1) can be triggered at any time throughout the user journey of your app. During the flow, the user has the ability to rate your app using the 1 to 5 star system and to add an optional comment. Once submitted, the review is sent to the Play Store and eventually displayed.

If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape.

I would recommend looking at the numpy broadcasting rules.

Here is the simplest example that has the key lines of code:

import numpy as np 
import matplotlib.pyplot as plt

H = np.array([[1, 2, 3, 4],
          [5, 6, 7, 8],
          [9, 10, 11, 12],
          [13, 14, 15, 16]])

plt.imshow(H, interpolation='none')
plt.show()

I think OldCurmudgeon and StaxMan are both correct but here is one sentence answer with simple example for you.

@JsonProperty(name), tells Jackson ObjectMapper to map the JSON property name to the annotated Java field's name.

//example of json that is submitted 
"Car":{
  "Type":"Ferrari",
}

//where it gets mapped 
public static class Car {
  @JsonProperty("Type")
  public String type;
 }

Perhaps the best two browser techs for this are Canvas, with Flash as a back up.

We tried VML on IE as backup for Canvas, but it was much slower than Flash. SVG was slower then all the rest.

With jSignature ( http://willowsystems.github.com/jSignature/ ) we used Canvas as primary, with fallback to Flash-based Canvas emulator (FlashCanvas) for IE8 and less. Id' say worked very well for us.

You could use a negative look-ahead assertion:

^(?!tbd_).+

Or a negative look-behind assertion:

(^.{1,3}$|^.{4}(?<!tbd_).*)

Or just plain old character sets and alternations:

^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

To build ontop of @tomloprod's answer. By the odd chance that you are using x-editable, and have a select2(v4) field and have multiple items you need to pre-select. You can use the following piece of code:

$("#select2field").on("shown", function(e, editable){
    $(["test1", "test2", "test3", "test4"]).each(function(k, v){
        // Create a DOM Option and pre-select by default~
        var newOption = new Option(v.text, v.id, true, true);
        // Append it to the select
        $(editable.input.$input).append(newOption).trigger('change');
     });
});

and here it is in action:

I ran into the same thing with the Bing Map API. URLEncoder just made things worse, but a replaceAll(" ","%20"); did the trick.

You should use the ANSI functions for reading a line, eg. fgets. After calling you need free() in calling context, eg:

...
const char *entirecontent=readLine(myFile);
puts(entirecontent);
free(entirecontent);
...

const char *readLine(FILE *file)
{
  char *lineBuffer=calloc(1,1), line[128];

  if ( !file || !lineBuffer )
  {
    fprintf(stderr,"an ErrorNo 1: ...");
    exit(1);
  }

  for(; fgets(line,sizeof line,file) ; strcat(lineBuffer,line) )
  {
    if( strchr(line,'\n') ) *strchr(line,'\n')=0;
    lineBuffer=realloc(lineBuffer,strlen(lineBuffer)+strlen(line)+1);
    if( !lineBuffer )
    {
      fprintf(stderr,"an ErrorNo 2: ...");
      exit(2);
    }
  }
  return lineBuffer;
}

Try:

assertThat(myClass.getMyItems(),
                          hasItem(hasProperty("YourProperty", is("YourValue"))));

If I may give an answer to an old thread; You can use PC Decrapifier to select programs you want to uninstall. PC Decrapifier will uninstall them one by one for you so you don't have to click them all seperately.

This is very useful for removing all the 'junk' - like the SQL Database tools - Visual Studio leaves behind even when uninstalled.

As of HTML5, the foreground colors of hyperlinks, among other things, are on track for standardization in the form of guidelines for expected default rendering behavior. In particular, taken from the section Phrasing content, the recommended default colors for unvisited and visited hyperlinks are the following:

:link { color: #0000EE; }
:visited { color: #551A8B; }

Notice that there is no recommended default for active hyperlinks (:link:active, :visited:active), however.

You can use these default colors and reasonably expect them to work. But keep in mind that a browser is free to ignore any or all of these guidelines, as it is never required to follow them. It is, however, recommended for a consistent user experience across browsers (which is how "expected" is defined in this context), so chances are that these colors will correspond to the defaults for most browsers. At worst, they still serve as reasonable approximations of the actual values.

In particular, the default unvisited and visited link colors in the latest versions of Firefox and Chrome are consistent with the above guidelines, but recent versions of IE report different values: unvisited links are rgb(0, 102, 204), or #0066CC, and visited links are rgb(128, 0, 128), or #800080. Older versions of Firefox (and possibly Safari/Chrome) had different defaults as well. Those are older versions, however; the main outlier today that I am aware of is IE. No word yet on whether this will change in Project Spartan — currently it still reflects the same values as the latest version of IE.

If you are looking for a standardized color scheme that is used by all browsers rather than suggested by HTML5, then there isn't one. Neither is there a way to revert to a browser's default value for a particular property on a particular element using pure CSS. You will have to either use the colors suggested by HTML5, or devise your own color scheme and use that instead. Either of these options will take precedence over a browser's defaults, regardless of browser.

If in doubt, you can always use the about:blank technique I described before to sniff out the default colors, as it remains applicable today. You can use this to sniff the active link color in all browsers, for example; in the latest version of Firefox (29 as of this update), it's rgb(238, 0, 0), or #EE0000.

sprintf() is the PHP function for all sorts of string formatting http://php.net/manual/en/function.sprintf.php

I use this function:

function formatDollars($dollars){
  return '$ '.sprintf('%0.2f', $dollars);
}

You can also invoke cmake itself to do this in a cross-platform way:

cmake -E env EnvironmentVariableName="Hello World" cmake ..

env [--unset=NAME]... [NAME=VALUE]... COMMAND [ARG]...

Run command in a modified environment.

Just be aware that this may only work the first time. If CMake re-configures with one of the consecutive builds (you just call e.g. make, one CMakeLists.txt was changed and CMake runs through the generation process again), the user defined environment variable may not be there anymore (in comparison to system wide environment variables).

So I transfer those user defined environment variables in my projects into a CMake cached variable:

cmake_minimum_required(VERSION 2.6)

project(PrintEnv NONE)

if (NOT "$ENV{EnvironmentVariableName}" STREQUAL "")
    set(EnvironmentVariableName "$ENV{EnvironmentVariableName}" CACHE INTERNAL "Copied from environment variable")
endif()

message("EnvironmentVariableName = ${EnvironmentVariableName}")

some_code >>/dev/null

for (i>0; i--;)

is probably wrong and should be

for (; i>0; i--)

instead. Note where I put the semicolons. The condition goes in the middle, not at the start.

The submodule approach is good if you want to maintain the project separately. However, if you really want to merge both projects into the same repository, then you have a bit more work to do.

The first thing would be to use git filter-branch to rewrite the names of everything in the second repository to be in the subdirectory where you would like them to end up. So instead of foo.c, bar.html, you would have projb/foo.c and projb/bar.html.

Then, you should be able to do something like the following:

git remote add projb [wherever]
git pull projb

The git pull will do a git fetch followed by a git merge. There should be no conflicts, if the repository you're pulling to does not yet have a projb/ directory.

Further searching indicates that something similar was done to merge gitk into git. Junio C Hamano writes about it here: http://www.mail-archive.com/[email protected]/msg03395.html

I had the same problem as one of my <div>'s had the margin set by the browser. It was quite annoying but then I figured out as most of the people said, it's a markup error.

I went back and checked my <head> section and my CSS link was like below:

<link rel="stylesheet" href="ex.css">

I included type in it and made it like below:

<link rel="stylesheet" type="text/css" href="ex.css">

My problem was solved.

Get-ADGroupMember "Group1" -recursive | Select-Object Name | Export-Csv c:\path\Groups.csv

I got this to work for me... I would assume that you could put "Group1, Group2, etc." or try a wildcard. I did pre-load AD into PowerShell before hand:

Get-Module -ListAvailable | Import-Module

Just another option, which I wrote:

DP_DateExtensions Library

It's overkill if this is all the date processing that you need, but it will do what you want.

Supports date/time formatting, date math (add/subtract date parts), date compare, date parsing, etc. It's liberally open sourced.

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("in.txt")
Dim inFile: Set inFile = obj.OpenTextFile("out.txt")

' Read file
Dim strRetVal : strRetVal = inFile.ReadAll
inFile.Close

' Write file
outFile.write (strRetVal)
outFile.Close

Are you trying to get visitors to old.com/about.htm to go to new.com/about.htm? If so, you can do this with a mod_rewrite rule in .htaccess:

RewriteEngine on

RewriteRule ^(.*)$ http://www.thenewdomain.com/$1 [R=permanent,L]

All previous answers are correct but were not sufficient for me on ArchLinux. I also needed to edit /etc/php/php.ini and to uncomment :

;extension=gd.so 

The initial ; on the line needs to be removed. After restarting Nginx via systemctl restart nginx, I was good to go.

Do it in the controller ( controller as syntax below)

controller:

vm.question= {};
vm.question.active = true;

form

<input ng-model="vm.question.active" type="checkbox" id="active" name="active">

You can also use a capture group (?P<user>pattern) and access the group like a dictionary match['user'].

string = '''someline abc\n
            someother line\n
            name my_user_name is valid\n
            some more lines\n'''

pattern = r'name (?P<user>.*) is valid'
matches = re.search(pattern, str(string), re.DOTALL)
print(matches['user'])

# my_user_name

Ubuntu 17.10 default doesn't have the ~/.vimrc file, we need create it and put the setting colorscheme color_scheme_name in it.

By the way, colorscheme desert is good scheme to choose.

I had to puzzle my way through self-signed certificates on Windows by combining bits and pieces from the given answers and further resources. Here is my own (and hopefully complete) walk-through. Hope it will spare you some of my own painful learning curve. It also contains infos on related topics that will pop up sooner or later when you create your own certs.

Create a self-signed certificate on Windows 10 and below

Don't use makecert.exe. It has been deprecated by Microsoft.
The modern way uses a Powershell command.

Windows 10:

Open Powershell with Administrator privileges:

New-SelfSignedCertificate  -DnsName "*.dev.local", "dev.local", "localhost"  -CertStoreLocation cert:\LocalMachine\My  -FriendlyName "Dev Cert *.dev.local, dev.local, localhost"  -NotAfter (Get-Date).AddYears(15)

Windows 8, Windows Server 2012 R2:

In Powershell on these systems the parameters -FriendlyName and -NotAfter do not exist. Simply remove them from the above command line.
Open Powershell with Administrator privileges:

New-SelfSignedCertificate  -DnsName "*.dev.local", "dev.local", "localhost"  -CertStoreLocation cert:\LocalMachine\My

An alternative is to use the method for older Windows version below, which allows you to use all the features of Win 10 for cert creation...

Older Windows versions:

My recommendation for older Windows versions is to create the cert on a Win 10 machine, export it to a .PFX file using an mmc instance (see "Trust the certificate" below) and import it into the cert store on the target machine with the old Windows OS. To import the cert do NOT right-click it. Although there is an "Import certificate" item in the context menu, it failed all my trials to use it on Win Server 2008. Instead open another mmc instance on the target machine, navigate to "Certificates (Local Computer) / Personal / Certificates", right click into the middle pane and select All tasks ? Import.

The resulting certificate

Both of the above commands create a certificate for the domains localhost and *.dev.local.
The Win10 version additionally has a live time of 15 years and a readable display name of "Dev Cert *.dev.local, dev.local, localhost".

Update: If you provide multiple hostname entries in parameter -DnsName (as shown above) the first of these entries will become the domain's Subject (AKA Common Name). The complete list of all hostname entries will be stored in the field Subject Alternative Name (SAN) of the certificate. (Thanks to @BenSewards for pointing that out.)

After creation the cert will be immediately available in any HTTPS bindings of IIS (instructions below).

Trust the certificate

The new cert is not part of any chain of trust and is thus not considered trustworthy by any browsers. To change that, we will copy the cert to the certificate store for Trusted Root CAs on your machine:

Open mmc.exe, File ? Add/Remove Snap-In ? choose "Certificates" in left column ? Add ? choose "Computer Account" ? Next ? "Local Computer..." ? Finish ? OK

In the left column choose "Certificates (Local Computer) / Personal / Certificates".
Find the newly created cert (in Win 10 the column "Friendly name" may help).
Select this cert and hit Ctrl-C to copy it to clipboard.

In the left column choose "Certificates (Local Computer) / Trusted Root CAs / Certificates".
Hit Ctrl-V to paste your certificate to this store.
The certificate should appear in the list of Trusted Root Authorities and is now considered trustworthy.

Use in IIS

Now you may go to IIS Manager, select the bindings of a local website ? Add ? https ? enter a host name of the form myname.dev.local (your cert is only valid for *.dev.local) and select the new certificate ? OK.

Add to hosts

Also add your host name to C:\Windows\System32\drivers\etc\hosts:

127.0.0.1  myname.dev.local

Happy

Now Chrome and IE should treat the certificate as trustworthy and load your website when you open up https://myname.dev.local.

Firefox maintains its own certificate store. To add your cert here, you must open your website in FF and add it to the exceptions when FF warns you about the certificate.

For Edge browser there may be more action needed (see further down).

Test the certificate

To test your certs, Firefox is your best choice. (Believe me, I'm a Chrome fan-boy myself, but FF is better in this case.)

Here are the reasons:

• Firefox uses its own SSL cache, which is purged on shift-reload. So any changes to the certs of your local websites will reflect immediately in the warnings of FF, while other browsers may need a restart or a manual purging of the windows SSL cache.
• Also FF gives you some valuable hints to check the validity of your certificate: Click on Advanced when FF shows its certificate warning. FF will show you a short text block with one or more possible warnings in the central lines of the text block:

The certificate is not trusted because it is self-signed.

This warning is correct! As noted above, Firefox does not use the Windows certificate store and will only trust this certificate, if you add an exception for it. The button to do this is right below the warnings.

The certificate is not valid for the name ...

This warning shows, that you did something wrong. The (wildcard) domain of your certificate does not match the domain of your website. The problem must be solved by either changing your website's (sub-)domain or by issuing a new certificate that matches. In fact you could add an exception in FF even if the cert does not match, but you would never get a green padlock symbol in Chrome with such a combination.

Firefox can display many other nice and understandable cert warnings at this place, like expired certs, certs with outdated signing algorithms, etc. I found no other browser that gave me that level of feedback to nail down any problems.

Which (sub-)domain pattern should I choose to develop?

In the above New-SelfSignedCertificate command we used the wildcard domain *.dev.local.

You may think: Why not use *.local?

Simple reason: It is illegal as a wildcard domain.
Wildcard certificates must contain at least a second level domain name.

So, domains of the form *.local are nice to develop HTTP websites. But not so much for HTTPS, because you would be forced to issue a new matching certificate for each new project that you start.

Important side notes:

• Valid host domains may ONLY contain letters a trough z, digits, hyphens and dots. No underscores allowed! Some browsers are really picky about this detail and can give you a hard time when they stubbornly refuse to match your domain motör_head.dev.local to your wildcard pattern *.dev.local. They will comply when you switch to motoer-head.dev.local.
• A wildcard in a certificate will only match ONE label (= section between two dots) in a domain, never more. *.dev.local matches myname.dev.local but NOT other.myname.dev.local!
• Multi level wildcards (*.*.dev.local) are NOT possible in certificates. So other.myname.dev.local can only be covered by a wildcard of the form *.myname.dev.local. As a result, it is best not to use a forth level domain part. Put all your variations into the third level part. This way you will get along with a single certificate for all your dev sites.

The problem with Edge

This is not really about self-signed certificates, but still related to the whole process:
After following the above steps, Edge may not show any content when you open up myname.dev.local.
The reason is a characteristic feature of the network management of Windows 10 for Modern Apps, called "Network Isolation".

To solve that problem, open a command prompt with Administrator privileges and enter the following command once:

CheckNetIsolation LoopbackExempt -a -n=Microsoft.MicrosoftEdge_8wekyb3d8bbwe

More infos about Edge and Network Isolation can be found here: https://blogs.msdn.microsoft.com/msgulfcommunity/2015/07/01/how-to-debug-localhost-on-microsoft-edge/

Here is how I do it. You will need to get the namespace URL and the element name from your generated code.

new JAXBElement(new QName("http://www.novell.com/role/service","userDN"),
                new String("").getClass(),testDN);

If your app is behind a trusted proxy (e.g. an AWS ELB or a correctly configured nginx), this code should work:

app.enable('trust proxy');
app.use(function(req, res, next) {
    if (req.secure){
        return next();
    }
    res.redirect("https://" + req.headers.host + req.url);
});

Notes:

• This assumes that you're hosting your site on 80 and 443, if not, you'll need to change the port when you redirect
• This also assumes that you're terminating the SSL on the proxy. If you're doing SSL end to end use the answer from @basarat above. End to end SSL is the better solution.
• app.enable('trust proxy') allows express to check the X-Forwarded-Proto header

This error means that the value indexed by the key "l_messages" is not of type hash, but rather something else. You've probably set it to that other value earlier in your code. Try various other value-getter commands, starting with GET, to see which one works and you'll know what type is actually here.

From your shell run:

pip2 install unicodecsv

And (unlike the original question) presuming you're using Python's built in csv module, turn
import csv into
import unicodecsv as csv in your code.

I addressed this issue this way.

I used a post message to the api to send the list of integers as data.

Then I returned the data as an ienumerable.

The sending code is as follows:

public override IEnumerable<Contact> Fill(IEnumerable<int> ids)
{
    IEnumerable<Contact> result = null;
    if (ids!=null&&ids.Count()>0)
    {
        try
        {
            using (var client = new HttpClient())
            {
                client.BaseAddress = new Uri("http://localhost:49520/");
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

                String _endPoint = "api/" + typeof(Contact).Name + "/ListArray";

                HttpResponseMessage response = client.PostAsJsonAsync<IEnumerable<int>>(_endPoint, ids).Result;
                response.EnsureSuccessStatusCode();
                if (response.IsSuccessStatusCode)
                {
                    result = JsonConvert.DeserializeObject<IEnumerable<Contact>>(response.Content.ReadAsStringAsync().Result);
                }

            }

        }
        catch (Exception)
        {

        }
    }
    return result;
}

The receiving code is as follows:

// POST api/<controller>
[HttpPost]
[ActionName("ListArray")]
public IEnumerable<Contact> Post([FromBody]IEnumerable<int> ids)
{
    IEnumerable<Contact> result = null;
    if (ids != null && ids.Count() > 0)
    {
        return contactRepository.Fill(ids);
    }
    return result;
}

It works just fine for one record or many records. The fill is an overloaded method using DapperExtensions:

public override IEnumerable<Contact> Fill(IEnumerable<int> ids)
{
    IEnumerable<Contact> result = null;
    if (ids != null && ids.Count() > 0)
    {
        using (IDbConnection dbConnection = ConnectionProvider.OpenConnection())
        {
            dbConnection.Open();
            var predicate = Predicates.Field<Contact>(f => f.id, Operator.Eq, ids);
            result = dbConnection.GetList<Contact>(predicate);
            dbConnection.Close();
        }
    }
    return result;
}

This allows you to fetch data from a composite table (the id list), and then return the records you are really interested in from the target table.

You could do the same with a view, but this gives you a little more control and flexibility.

In addition, the details of what you are seeking from the database are not shown in the query string. You also do not have to convert from a csv file.

You have to keep in mind when using any tool like the web api 2.x interface is that the get, put, post, delete, head, etc., functions have a general use, but are not restricted to that use.

So, while post is generally used in a create context in the web api interface, it is not restricted to that use. It is a regular html call that can be used for any purpose permitted by html practice.

In addition, the details of what is going on are hidden from those "prying eyes" we hear so much about these days.

The flexibility in naming conventions in the web api 2.x interface and use of regular web calling means you send a call to the web api that misleads snoopers into thinking you are really doing something else. You can use "POST" to really retrieve data, for example.

Creator of the change-case extension here. I've updated the extension to support spanning lines.

To map the upper case command to a keybinding (e.g. CTRL+T+U), click File -> Preferences -> Keyboard shortcuts, and insert the following into the json config:

{
  "key": "ctrl+t ctrl+u",
  "command": "extension.changeCase.upper",
  "when": "editorTextFocus"
}

EDIT:

With the November 2016 (release notes) update of VSCode, there is built-in support for converting to upper case and lower case via the commands editor.action.transformToUppercase and editor.action.transformToLowercase. These don't have default keybindings. They also work with multi-line blocks.

The change-case extension is still useful for other text transformations, e.g. camelCase, PascalCase, snake_case, kebab-case, etc.

Collections is a class which has some static methods and that method returns the collection. Collection is an interface,rather than root interface in collection hierarchy.

"-P" is the right option, please read on for more related information:

wget -nd -np -P /dest/dir --recursive http://url/dir1/dir2

Relevant snippets from man pages for convenience:

   -P prefix
   --directory-prefix=prefix
       Set directory prefix to prefix.  The directory prefix is the directory where all other files and subdirectories will be saved to, i.e. the top of the retrieval tree.  The default is . (the current directory).

   -nd
   --no-directories
       Do not create a hierarchy of directories when retrieving recursively.  With this option turned on, all files will get saved to the current directory, without clobbering (if a name shows up more than once, the
       filenames will get extensions .n).


   -np
   --no-parent
       Do not ever ascend to the parent directory when retrieving recursively.  This is a useful option, since it guarantees that only the files below a certain hierarchy will be downloaded.

To connect from Terminal to AWS AMI:

chmod 400 mykey.pem

ssh -i mykey.pem [email protected]

Method to replace substring in a sentence using React:

      }
    });
    return newStr;
  };

RunMethodHere

pip will not try to make things difficult for you on purpose.

The thing is commands based files are always installed in /bin folders they can be anywhere on the system path.

I had the same problem and I found that I have these files in my

~/.local/bin/

folder instead of

/usr/loca/bin/

which is the common case, but I think they changed the default path to

~ or $HOME

directory because its more isolate for the pip installations and provides a distinction between apt-get packages and pip packages.

So coming to the point you have two choices here either you go to your .bashrc and make changes like this

# for virtualenv wrapper
export WORKON_HOME=$HOME/Envs
export PROJECT_HOME=$HOME/Devel
source $HOME/.local/bin/virtualenvwrapper.sh

and than create a directory virtualenvwrapper under /usr/share/ and than symlink your virtualwrapper_lazy.sh like this

sudo ln -s ~/.local/bin/virtualenvwrapper_lazy.sh /usr/share/virtualenvwrapper/virtualenvwrapper_lazy.sh

and you can check if your workon command is working which will list your existing virtualenv's.

400 Bad Request is proper HTTP status code for your use case. The code is defined by HTTP/0.9-1.1 RFC.

The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.

http://tools.ietf.org/html/rfc2616#section-10.4.1

422 Unprocessable Entity is defined by RFC 4918 - WebDav. Note that there is slight difference in comparison to 400, see quoted text below.

This error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

To keep uniform interface you should use 422 only in a case of XML responses and you should also support all status codes defined by Webdav extension, not just 422.

http://tools.ietf.org/html/rfc4918#page-78

See also Mark Nottingham's post on status codes:

it’s a mistake to try to map each part of your application “deeply” into HTTP status codes; in most cases the level of granularity you want to be aiming for is much coarser. When in doubt, it’s OK to use the generic status codes 200 OK, 400 Bad Request and 500 Internal Service Error when there isn’t a better fit.

How to Think About HTTP Status Codes

This approach worked for me and is less cluttered than some solutions:

try:
  from ..components.core import GameLoopEvents
except ValueError:
  from components.core import GameLoopEvents

The parent directory is in my PYTHONPATH, and there are __init__.py files in the parent directory and this directory.

The above always worked in python 2, but python 3 sometimes hit an ImportError or ModuleNotFoundError (the latter is new in python 3.6 and a subclass of ImportError), so the following tweak works for me in both python 2 and 3:

try:
  from ..components.core import GameLoopEvents
except ( ValueError, ImportError):
  from components.core import GameLoopEvents

The way I do this is to create a remote (bare) repository (on a separate drive, USB Key, backup server or even github) and then use push --mirror to make that remote repo look exactly like my local one (except the remote is a bare repository).

This will push all refs (branches and tags) including non-fast-forward updates. I use this for creating backups of my local repository.

The man page describes it like this:

Instead of naming each ref to push, specifies that all refs under $GIT_DIR/refs/ (which includes but is not limited to refs/heads/, refs/remotes/, and refs/tags/) be mirrored to the remote repository. Newly created local refs will be pushed to the remote end, locally updated refs will be force updated on the remote end, and deleted refs will be removed from the remote end. This is the default if the configuration option remote.<remote>.mirror is set.

I made an alias to do the push:

git config --add alias.bak "push --mirror github"

Then, I just run git bak whenever I want to do a backup.

PowerShell solution that shows all of the instances on the host as well as their incoming traffic addresses. The second bit might be helpful if all you know is the DNS:

ForEach ($SQL_Proc in Get-Process | Select-Object -Property ProcessName, Id | Where-Object {$_.ProcessName -like "*SQL*"})
{
    Get-NetTCPConnection | `
     Where-Object {$_.OwningProcess -eq $SQL_Proc.id} | `
      Select-Object -Property `
                                @{Label ="Process_Name";e={$SQL_Proc.ProcessName}}, `
                                @{Label ="Local_Address";e={$_.LocalAddress + ":" + $_.LocalPort }},  `
                                @{Label ="Remote_Address";e={$_.RemoteAddress + ":" + $_.RemotePort}}, State | `
      Format-Table
} 

Try This

SELECT @PrimaryContactKey = c.PrimaryCntctKey
FROM tarcustomer c, tarinvoice i
WHERE i.custkey = c.custkey 
    AND i.invckey = @tmp_key

UPDATE tarinvoice SET confirmtocntctkey = @PrimaryContactKey 
WHERE invckey = @tmp_key
FETCH NEXT FROM @get_invckey INTO @tmp_key

You would declare this variable outside of your loop as just a standard TSQL variable.

I should also note that this is how you would do it for any type of select into a variable, not just when dealing with cursors.

In .Net 2.0, you can use Console.Beep().

// Default beep
Console.Beep();

You can also specify the frequency and length of the beep in milliseconds.

// Beep at 5000 Hz for 1 second
Console.Beep(5000, 1000);

this solved my issue, it was working fine with

var value = item[index].id;
$("#select2").val(value);

but not showing selected value, so

$("#select2").val(value).change();

works fine for me.

If you're in an async function you can simply do it in one line:

console.log(1);
await new Promise(resolve => setTimeout(resolve, 3000)); // 3 sec
console.log(2);

FYI, if target is NodeJS you can use this if you want (it's a predefined promisified setTimeout function):

await setTimeout[Object.getOwnPropertySymbols(setTimeout)[0]](3000) // 3 sec

in linux if you want to sort directories then du -hs * | sort -h

From https://texfaq.org/FAQ-nohyph:

TeX won’t hyphenate a word that’s already been hyphenated. For example, the (caricature) English surname Smyth-Postlethwaite wouldn’t hyphenate, which could be troublesome. This is correct English typesetting style (it may not be correct for other languages), but if needs must, you can replace the hyphen in the name with a \hyph command, defined

 \def\hyph{-\penalty0\hskip0pt\relax}

This is not the sort of thing this FAQ would ordinarily recommend… The hyphenat package defines a bundle of such commands (for introducing hyphenation points at various punctuation characters).

Or you could \newcommand a command that expands to multi-discipli\-nary (use Search + Replace All to replace existing words).

The simple command 'keytool' also works on Windows and/or with Cygwin.

IF you're using Cygwin here is the modified command that I used from the bottom of "S.Botha's" answer :

1. make sure you identify the JRE inside the JDK that you will be using
2. Start your prompt/cygwin as admin
3. go inside the bin directory of that JDK e.g. cd /cygdrive/c/Program\ Files/Java/jdk1.8.0_121/jre/bin

4. Execute the keytool command from inside it, where you provide the path to your new Cert at the end, like so:

   ./keytool.exe -import -trustcacerts -keystore ../lib/security/cacerts  -storepass changeit -noprompt -alias myownaliasformysystem -file "D:\Stuff\saved-certs\ca.cert"
   

Notice, because if this is under Cygwin you're giving a path to a non-Cygwin program, so the path is DOS-like and in quotes.

In this situation I would try:

$(document).on('click','.addproduct', function(){

    //your code here

 });

then, if you need to perform something in the other elements with the same class on click on one ot them you can loop through the elements:

$(document).on('click','.addproduct', function(){
   $('.addproduct').each( function(){

      //your code here
     }
  );
 }
);

Now in c++11 we have

#include <string>
string s = std::to_string(123);

Link to reference: http://en.cppreference.com/w/cpp/string/basic_string/to_string

You can use Time::Piece, which shouldn't need installing as it is a core module and has been distributed with Perl 5 since version 10.

use Time::Piece;

my $date = localtime->strftime('%m/%d/%Y');
print $date;

output

06/13/2012

Update

You may prefer to use the dmy method, which takes a single parameter which is the separator to be used between the fields of the result, and avoids having to specify a full date/time format

my $date = localtime->dmy('/');

This produces an identical result to that of my original solution

just use this at the end of your button click event

protected void btnAddButton_Click(object sender, EventArgs e)
{
   ... save data routin 
     Response.Redirect(Request.Url.AbsoluteUri);
}

DateTime.Ticks will account for the time. Use .Ticks on the DateTime to convert your dates into longs. Then just use a simple if stmt to see if your target date falls between.

// Assuming you know d2 > d1
if (targetDt.Ticks > d1.Ticks && targetDt.Ticks < d2.Ticks)
{
    // targetDt is in between d1 and d2
}  

The answers here do an excellent job in defining both monoids and monads, however, they still don't seem to answer the question:

And on a less important note, is this true and if so could you give an explanation (hopefully one that can be understood by someone who doesn't have much Haskell experience)?

The crux of the matter that is missing here, is the different notion of "monoid", the so-called categorification more precisely -- the one of monoid in a monoidal category. Sadly Mac Lane's book itself makes it very confusing:

All told, a monad in X is just a monoid in the category of endofunctors of X, with product × replaced by composition of endofunctors and unit set by the identity endofunctor.

Main confusion

Why is this confusing? Because it does not define what is "monoid in the category of endofunctors" of X. Instead, this sentence suggests taking a monoid inside the set of all endofunctors together with the functor composition as binary operation and the identity functor as a monoidal unit. Which works perfectly fine and turns into a monoid any subset of endofunctors that contains the identity functor and is closed under functor composition.

Yet this is not the correct interpretation, which the book fails to make clear at that stage. A Monad f is a fixed endofunctor, not a subset of endofunctors closed under composition. A common construction is to use f to generate a monoid by taking the set of all k-fold compositions f^k = f(f(...)) of f with itself, including k=0 that corresponds to the identity f^0 = id. And now the set S of all these powers for all k>=0 is indeed a monoid "with product × replaced by composition of endofunctors and unit set by the identity endofunctor".

And yet:

• This monoid S can be defined for any functor f or even literally for any self-map of X. It is the monoid generated by f.
• The monoidal structure of S given by the functor composition and the identity functor has nothing do with f being or not being a monad.

And to make things more confusing, the definition of "monoid in monoidal category" comes later in the book as you can see from the table of contents. And yet understanding this notion is absolutely critical to understanding the connection with monads.

(Strict) monoidal categories

Going to Chapter VII on Monoids (which comes later than Chapter VI on Monads), we find the definition of the so-called strict monoidal category as triple (B, *, e), where B is a category, *: B x B-> B a bifunctor (functor with respect to each component with other component fixed) and e is a unit object in B, satisfying the associativity and unit laws:

(a * b) * c = a * (b * c)
a * e = e * a = a

for any objects a,b,c of B, and the same identities for any morphisms a,b,c with e replaced by id_e, the identity morphism of e. It is now instructive to observe that in our case of interest, where B is the category of endofunctors of X with natural transformations as morphisms, * the functor composition and e the identity functor, all these laws are satisfied, as can be directly verified.

What comes after in the book is the definition of the "relaxed" monoidal category, where the laws only hold modulo some fixed natural transformations satisfying so-called coherence relations, which is however not important for our cases of the endofunctor categories.

Monoids in monoidal categories

Finally, in section 3 "Monoids" of Chapter VII, the actual definition is given:

A monoid c in a monoidal category (B, *, e) is an object of B with two arrows (morphisms)

mu: c * c -> c
nu: e -> c

making 3 diagrams commutative. Recall that in our case, these are morphisms in the category of endofunctors, which are natural transformations corresponding to precisely join and return for a monad. The connection becomes even clearer when we make the composition * more explicit, replacing c * c by c^2, where c is our monad.

Finally, notice that the 3 commutative diagrams (in the definition of a monoid in monoidal category) are written for general (non-strict) monoidal categories, while in our case all natural transformations arising as part of the monoidal category are actually identities. That will make the diagrams exactly the same as the ones in the definition of a monad, making the correspondence complete.

Conclusion

In summary, any monad is by definition an endofunctor, hence an object in the category of endofunctors, where the monadic join and return operators satisfy the definition of a monoid in that particular (strict) monoidal category. Vice versa, any monoid in the monoidal category of endofunctors is by definition a triple (c, mu, nu) consisting of an object and two arrows, e.g. natural transformations in our case, satisfying the same laws as a monad.

Finally, note the key difference between the (classical) monoids and the more general monoids in monoidal categories. The two arrows mu and nu above are not anymore a binary operation and a unit in a set. Instead, you have one fixed endofunctor c. The functor composition * and the identity functor alone do not provide the complete structure needed for the monad, despite that confusing remark in the book.

Another approach would be to compare with the standard monoid C of all self-maps of a set A, where the binary operation is the composition, that can be seen to map the standard cartesian product C x C into C. Passing to the categorified monoid, we are replacing the cartesian product x with the functor composition *, and the binary operation gets replaced with the natural transformation mu from c * c to c, that is a collection of the join operators

join: c(c(T))->c(T)

for every object T (type in programming). And the identity elements in classical monoids, which can be identified with images of maps from a fixed one-point-set, get replaced with the collection of the return operators

return: T->c(T) 

But now there are no more cartesian products, so no pairs of elements and thus no binary operations.

Although this does not directly address your question, you can actually sort your data by cell colour in Excel (which then makes it pretty easy to label all records with a particular colour in the same way and, hence, condition upon this label).

In Excel 2010, you can do this by going to Data -> Sort -> Sort On "Cell Colour".

You should above all never manually copy/download/move/include the individual servletcontainer-specific libraries like servlet-api.jar

@BalusC,

I would prefer to use the exact classes that my application is going to use rather than one provided by Eclipse (when I am feeling like a paranoid developer).

Another solution would be to use Eclipse "Configure Build Path" > Libraries > Add External Jars, and add servlet api of whatever Container one chooses to use.

And follow @kaustav datta's solution when using ant to build - have a property like tomcat.home or weblogic.home. However it introduces another constraint that the developer must install Weblogic on his/her local machine if weblogic is being used ! Any other cleaner solution?

Omega is one of them, I played it on C64 :)

I've solved this problem by using the search function on Docker's website where '*' is a valid search that returns 200k repositories and then I crawled each invididual page. HTML parsing allows me to extract all the image names on each page.

Even after removing the remaking the directories, the datanode wasn't starting. So, I started it manually using bin/hadoop datanode It did not reach any conclusion. I opened another terminal from the same username and did jps and it showed me the running datanode process. It's working, but I just have to keep the unfinished terminal open by the side.

I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).

If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::.

Something along these lines:

create view view1
as 
select table1.col1,table2.col1,table3.col3
from table1 
inner join
table2 
inner join 
table3
on 
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;

Notice the varchar typecasting on the table1.col4.

Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.

Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

The first thing to do (if not already done) is to split your database into a front end (with all the forms/reports etc) and a back end(with all the data). The second thing is to setup version control on the front end.

The way I have done that in a lot of my databases is to have the users run a small “jumper” database to open the main database. This jumper does the following things

• Checks to see if the user has the database on their C drive

• If they do not then install and run

• If they do then check what version they have

• If the version numbers do not match then copy down the latest version

• Open the database

This whole checking process normally takes under half a second. Using this model you can do all your development on a separate database then when you are ready to “release” you just put the new mde up onto the network share and the next time the user opens the jumper the latest version is copied down.

There are also other things to think about in multiuser database and it might be worth checking for the common mistakes such as binding a form to a whole table etc

Hope this could help Too

$('#selectBox option[value="3"]').attr('selected', true);

Both Activity and Service actually extend Context so you can simply use this as your Context within your Service.

NotificationManager notificationManager =
    (NotificationManager) getSystemService(Service.NOTIFICATION_SERVICE);
Notification notification = new Notification(/* your notification */);
PendingIntent pendingIntent = /* your intent */;
notification.setLatestEventInfo(this, /* your content */, pendingIntent);
notificationManager.notify(/* id */, notification);

IB and Swift

Given the flowing layout where yellow is the superview and red, green, and blue are sibling subviews of yellow,

the goal is to move a subview (let's say green) to the top.

In Interface Builder

In the Interface Builder all you need to do is drag the view you want showing on the top to the bottom of the list in the Documents Outline.

Alternatively, you can select the view and then in the menu go to Editor > Arrange > Send to Front.

In Swift

There are a couple of different ways to do this programmatically.

Method 1

yellowView.bringSubviewToFront(greenView)

• This method is the programmatic equivalent of the IB answer above.

• It only works if the subviews are siblings of each other.

• An array of the subviews is contained in yellowView.subviews. Here, bringSubviewToFront moves the greenView from index 0 to 2. This can be observed with

    print(yellowView.subviews.indexOf(greenView))
  

Method 2

greenView.layer.zPosition = 1

• This method just moves the 3D position of the layer higher (closer to the user) on the z-axis. Since the default is 0 for all the other views, the result is that the greenView looks like it is on top. However, it still remains at index 0 of the yellowView.subviews array. This can cause some unexpected results, though, because things like tap events will still go first to the view with the highest index number. For that reason, it might be better to go with Method 1 above.
• The zPosition could be set to CGFloat.greatestFiniteMagnitude (CGFloat(FLT_MAX) in older versions of Swift) to ensure that it is on top.

Small And Best One

#test{
width: 202px;
}
<select id="test" size="1" name="mrraja">

open cmd and type

npm i -g npm

Press the hammer to the left of the green arrow (run), for the program to clean & build project. Press green arrow. Select Main Class.

Hope it works for u.

select column1 as xyz,
      column2 as pqr,
.....

from TableName;

And if you want to add a row, you can use a dictionary:

df = pd.DataFrame()
df = df.append({'name': 'Zed', 'age': 9, 'height': 2}, ignore_index=True)

which gives you:

   age  height name
0    9       2  Zed

Microsoft Docs stands for:

Once an exception is thrown, part of the information it carries is the stack trace. The stack trace is a list of the method call hierarchy that starts with the method that throws the exception and ends with the method that catches the exception. If an exception is re-thrown by specifying the exception in the throw statement, the stack trace is restarted at the current method and the list of method calls between the original method that threw the exception and the current method is lost. To keep the original stack trace information with the exception, use the throw statement without specifying the exception.

Have you tried to remove "pytrace=True" ?

pytest.fail(exc, pytrace=True) # before
pytest.fail(exc) # after

Have you tried to run with '--fulltrace' ?

There is a catch when using listdir. The os.path.isdir(identifier) must be an absolute path. To pick subdirectories you do:

for dirname in os.listdir(rootdir):
  if os.path.isdir(os.path.join(rootdir, dirname)):
     print("I got a subdirectory: %s" % dirname)

The alternative is to change to the directory to do the testing without the os.path.join().

This will return true if input is all numbers. Don't know if it's any better than TryParse, but it will work.

Regex.IsMatch(input, @"^\d+$")

If you just want to know if it has one or more numbers mixed in with characters, leave off the ^ + and $.

Regex.IsMatch(input, @"\d")

Edit: Actually I think it is better than TryParse because a very long string could potentially overflow TryParse.

Oracle 9i+ (maybe 8i too) has FIRST/LAST aggregate functions, that make computation over groups of rows according to row's rank in group. Assuming all rows as one group, you'll get what you want without subqueries:

SELECT
  max(MEMBSHIP_ID)
  keep (
      dense_rank first
      order by paym_date desc NULLS LAST
  ) as LATEST_MEMBER_ID
FROM user_payment
WHERE user_id=1

The code is valid (i.e, will compile and execute) in both cases.

One of my lecturers at Uni told us that it is not desirable to have continue, return statements in any loop - for or while. The reason for this is that when examining the code, it is not not immediately clear whether the full length of the loop will be executed or the return or continue will take effect.

See Why is continue inside a loop a bad idea? for an example.

The key point to keep in mind is that for simple scenarios like this it doesn't (IMO) matter but when you have complex logic determining the return value, the code is 'generally' more readable if you have a single return statement instead of several.

With regards to the Garbage Collection - I have no idea why this would be an issue.

You can't. It's a browser feature there to prevent sites from showing hundreds of alerts to prevent you from leaving.

You can, however, look into modal popups like jQuery UI Dialog. These are javascript alert boxes that show a custom dialog. They don't use the default alert() function and therefore, bypass the issue you're running into completely.

I've found that an apps that has a lot of message boxes and confirms has a much better user experience if you use custom dialogs instead of the default alerts and confirms.

in this code data is a two dimensional array of table data

let oTable = document.getElementById('datatable-id');
let data = [...oTable.rows].map(t => [...t.children].map(u => u.innerText))

Some great examples and libs presented in this thread, but they didn't quite have what I was looking for. My approach: angular-validity -- a promise based validation lib for asynchronous validation, with optional Bootstrap styling baked-in.

An angular-validity solution for the OP's use case might look something like this:

<input  type="text" name="field4" ng-model="field4"
        validity="eval"
        validity-eval="!(field1 && field2 && field3 && !field4)"
        validity-message-eval="This field is required">

Here's a Fiddle, if you want to take it for a spin. The lib is available on GitHub, has detailed documentation, and plenty of live demos.

You're asking it to parse the JSON text something (not "something"). That's invalid JSON, strings must be in double quotes.

If you want an equivalent to your first example:

var s = '"something"';
var result = JSON.parse(s);

    public static bool[] Convert(int[] input, int length)
    {
        var ret = new bool[length];
        var siz = sizeof(int) * 8;
        var pow = 0;
        var cur = 0;

        for (var a = 0; a < input.Length && cur < length; ++a)
        {
            var inp = input[a];

            pow = 1;

            if (inp > 0)
            {
                for (var i = 0; i < siz && cur < length; ++i)
                {
                    ret[cur++] = (inp & pow) == pow;

                    pow *= 2;
                }
            }
            else
            {
                for (var i = 0; i < siz && cur < length; ++i)
                {
                    ret[cur++] = (inp & pow) != pow;

                    pow *= 2;
                }
            }
        }

        return ret;
    }

Simply use :

"SELECT * FROM `trees` WHERE LOWER(trees.`title`) LIKE  '%elm%'";

Or Use

"SELECT * FROM `trees` WHERE LCASE(trees.`title`) LIKE  '%elm%'";

Both functions works same

Yes you can run keras models on GPU. Few things you will have to check first.

1. your system has GPU (Nvidia. As AMD doesn't work yet)
2. You have installed the GPU version of tensorflow
3. You have installed CUDA installation instructions
4. Verify that tensorflow is running with GPU check if GPU is working

sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

for TF > v2.0

sess = tf.compat.v1.Session(config=tf.compat.v1.ConfigProto(log_device_placement=True))

(Thanks @nbro and @Ferro for pointing this out in the comments)

OR

from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())

output will be something like this:

[
  name: "/cpu:0"device_type: "CPU",
  name: "/gpu:0"device_type: "GPU"
]

Once all this is done your model will run on GPU:

To Check if keras(>=2.1.1) is using GPU:

from keras import backend as K
K.tensorflow_backend._get_available_gpus()

All the best.

There might be a fix to <input type="button"> - but if there is, I don't know it.

Otherwise, a good option seems to be to replace it with a carefully styled a element.

Example: http://jsfiddle.net/Uka5v/

.button {
    background-color: #E3E1B8; 
    padding: 2px 4px;
    font: 13px sans-serif;
    text-decoration: none;
    border: 1px solid #000;
    border-color: #aaa #444 #444 #aaa;
    color: #000
}

Upsides include that the a element will style consistently between different (older) versions of Internet Explorer without any extra work, and I think my link looks nicer than that button :)

You can reload parent window location using :

window.opener.location.href = window.opener.location.href;

x = float(raw_input("enter number between 0 and 1: "))

p = 0
while ((2**p)*x) %1 != 0:
    p += 1
    # print p

    num = int (x * (2 ** p))
    # print num

    result = ''
    if num == 0:
        result = '0'
    while num > 0:
        result = str(num%2) + result
        num = num / 2

    for i in range (p - len(result)):
        result = '0' + result
    result = result[0:-p] + '.' + result[-p:]

print result #this will print result for the decimal portion

The problem in your initial definition of the class is that you've written:

class name(object, name):

This means that the class inherits the base class called "object", and the base class called "name". However, there is no base class called "name", so it fails. Instead, all you need to do is have the variable in the special init method, which will mean that the class takes it as a variable.

class name(object):
  def __init__(self, name):
    print name

If you wanted to use the variable in other methods that you define within the class, you can assign name to self.name, and use that in any other method in the class without needing to pass it to the method.

For example:

class name(object):
  def __init__(self, name):
    self.name = name
  def PrintName(self):
    print self.name

a = name('bob')
a.PrintName()
bob

In case you cannot use different stylesheet by dynamically loading it, you can use this function to modify CSS class. Hope it helps you...

function changeCss(className, classValue) {
    // we need invisible container to store additional css definitions
    var cssMainContainer = $('#css-modifier-container');
    if (cssMainContainer.length == 0) {
        var cssMainContainer = $('<div id="css-modifier-container"></div>');
        cssMainContainer.hide();
        cssMainContainer.appendTo($('body'));
    }

    // and we need one div for each class
    classContainer = cssMainContainer.find('div[data-class="' + className + '"]');
    if (classContainer.length == 0) {
        classContainer = $('<div data-class="' + className + '"></div>');
        classContainer.appendTo(cssMainContainer);
    }

    // append additional style
    classContainer.html('<style>' + className + ' {' + classValue + '}</style>');
}

This function will take any class name and replace any previously set values with the new value. Note, you can add multiple values by passing the following into classValue: "background: blue; color:yellow".

What about a simple while loop?

while times > 0:
    do_something()
    times -= 1

You already have the variable; why not use it?

It is not quite clear what function you are talking about and if you need 2 separate branches or one. Assuming one:

Change your first line to

$slide = '';
if (isset($_GET["id"]))
{
    $slide = $_GET["id"];
}

I think this will work for int, long and string values.

List<int> list = new List<int>(new int[]{ 2, 3, 7 });


var animals = new List<string>() { "bird", "dog" };

Update your last wrong commit message with the new commit message in one line:

git commit --amend -m "your new commit message"

Or, try Git reset like below:

# You can reset your head to n number of commit
# NOT a good idea for changing last commit message,
# but you can get an idea to split commit into multiple commits
git reset --soft HEAD^

# It will reset you last commit. Now, you
# can re-commit it with new commit message.

Using reset to split commits into smaller commits

git reset can help you to break one commit into multiple commits too:

# Reset your head. I am resetting to last commits:
git reset --soft HEAD^
# (You can reset multiple commit by doing HEAD~2(no. of commits)

# Now, reset your head for splitting it to multiple commits
git reset HEAD

# Add and commit your files separately to make multiple commits: e.g
git add app/
git commit -m "add all files in app directory"

git add config/
git commit -m "add all files in config directory"

Here you have successfully broken your last commit into two commits.

Here is a version of the currently accepted answer (from @Trevor) with key instead of keyCode:

document.querySelector('#txtSearch').addEventListener('keypress', function (e) {
    if (e.key === 'Enter') {
      // code for enter
    }
});

Your need to use the html/xhtml break character:

<br />

I usually place commands in parentheses $(commandStr), if that doesn't help I find bash debug mode great, run the script as bash -x script

Had this problem with angular, using an auth interceptor to edit the header, before the request gets executed. We used an api-token for authentification, so i had credentials enabled. now, it seems it is not neccessary/allowed anymore

@Injectable()
export class AuthInterceptor implements HttpInterceptor {
  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    req = req.clone({
      //withCredentials: true, //not needed anymore
      setHeaders: {
        'Content-Type' : 'application/json',
        'API-TOKEN' : 'xxx'
      },
    });
    
    return next.handle(req);
  }

Besides that, there is no side effects right now.

Clearing metadata helped me or change the workspace.

I spend a lot time to discover why my code could not find my file running Python 3 on the Windows system. So I added . before / and everything worked fine:

import os

script_dir = os.path.dirname(__file__)
file_path = os.path.join(script_dir, './output03.txt')
print(file_path)
fptr = open(file_path, 'w')

change the code to the following

<%! List eList = (ArrayList)session.getAttribute("empList");%>
....
<table>
    <%
    for(int i=0; i<eList.length;i++){%>
        <tr>
            <td><%= ((Employee)eList[i]).getEid() %></td>
            <td><%= ((Employee)eList[i]).getEname() %></td>  
        </tr>
      <%}%>
</table>

I would like to improve the code. When you canel the aSyncTask the onCancelled() (callback method of aSyncTask) gets automatically called, and there you can hide your progressBarDialog.

You can include this code as well:

public class information extends AsyncTask<String, String, String>
    {
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
        }

        @Override
        protected String doInBackground(String... arg0) {
            return null;
        }

        @Override
        protected void onPostExecute(String result) {
            super.onPostExecute(result);
            this.cancel(true);
        }

        @Override
        protected void onProgressUpdate(String... values) {
            super.onProgressUpdate(values);
        }

        @Override
        protected void onCancelled() {
            Toast.makeText(getApplicationContext(), "asynctack cancelled.....", Toast.LENGTH_SHORT).show();
            dialog.hide(); /*hide the progressbar dialog here...*/
            super.onCancelled();
        }

    }

When and where to use \\\" instead. OK if you are like me you will feel just as silly as I did when I realized what I was doing after I found this thread.

If you're making a .json text file/stream and importing the data from there then the main stream answer of just one backslash before the double quotes:\" is the one you're looking for.

However if you're like me and you're trying to get the w3schools.com "Tryit Editor" to have a double quotes in the output of the JSON.parse(text), then the one you're looking for is the triple backslash double quotes \\\". This is because you're building your text string within an HTML <script> block, and the first double backslash inserts a single backslash into the string variable then the following backslash double quote inserts the double quote into the string so that the resulting script string contains the \" from the standard answer and the JSON parser will parse this as just the double quotes.

<script>
  var text="{";
  text += '"quip":"\\\"If nobody is listening, then you\'re likely talking to the wrong audience.\\\""';
  text += "}";
  var obj=JSON.parse(text);
</script>

+1: since it's a JavaScript text string, a double backslash double quote \\" would work too; because the double quote does not need escaped within a single quoted string eg '\"' and '"' result in the same JS string.

myList.Where(item=>item.Name == nameToExtract)

   static void PrintSmallestLargest(int[] arr)
    {
        if (arr.Length > 0)
        {
            int small = arr[0];
            int large = arr[0];
            for (int i = 0; i < arr.Length; i++)
            {
                if (large < arr[i])
                {
                    int tmp = large;
                    large = arr[i];
                    arr[i] = large;
                }
                if (small > arr[i])
                {
                    int tmp = small;
                    small = arr[i];
                    arr[i] = small;
                }
            }
            Console.WriteLine("Smallest is {0}", small);
            Console.WriteLine("Largest is {0}", large);
        }
    }

This way you can have smallest and largest number in a single loop.

If you're using more than one argument it has to be in a tuple (note the extra parentheses):

'%s in %s' % (unicode(self.author),  unicode(self.publication))

As EOL points out, the unicode() function usually assumes ascii encoding as a default, so if you have non-ASCII characters, it's safer to explicitly pass the encoding:

'%s in %s' % (unicode(self.author,'utf-8'),  unicode(self.publication('utf-8')))

And as of Python 3.0, it's preferred to use the str.format() syntax instead:

'{0} in {1}'.format(unicode(self.author,'utf-8'),unicode(self.publication,'utf-8'))

If you're getting something like getElementById call returns null, it's probably because the function is running, but the ID hasn't had time to load in the DOM.

Try using Will's answer (towards the top) with a delay. Example:

angular.module('MyApp', [])

.controller('MyCtrl', [function() {
    $scope.sleep = (time) => {
        return new Promise((resolve) => setTimeout(resolve, time));
    };
    angular.element(document).ready(function () {
        $scope.sleep(500).then(() => {        
            //code to run here after the delay
        });
    });
}]);

FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.

Some references:

• FileZilla Client command-line arguments
• https://trac.filezilla-project.org/ticket/2317
• How do I send a file with FileZilla from the command line?

Though you can use any other client that allows automation.

You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).

Combine WinSCP scripting capabilities with Windows Scheduler:

• Automate file transfers to FTP server or SFTP server;
• Schedule file transfers to FTP/SFTP server

A typical WinSCP script for upload (with SFTP) looks like:

open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close

With FTP, just replace the sftp:// with the ftp:// and remove the -hostkey="..." switch.

Similarly for download: How to schedule an automatic FTP download on Windows?

WinSCP can even generate a script from an imported FileZilla session.

For details, see the guide to FileZilla automation.

(I'm the author of WinSCP)

Another option, if you are using SFTP, is the psftp.exe client from PuTTY suite.

I just want to correct a point here. ELF file is produced by the Linker, not the compiler.

The Compiler mission ends after producing the object files (*.o) out of the source code files. Linker links all .o files together and produces the ELF.

for a complete offline android studio 3.5.0 installation - you need to download all these below components

android studio, gradle, android gradle plugin and sdk.

here is a detailed step by step Stackoverflow answer for the question

how to install android studio full offline

First off, what I have found working with Angular2 is that the url with a query string would be /path;query=value1

To access it in a component you use So is this, but now follows a code block:

    constructor(params: RouteParams){
    var val = params.get("query");
    }

As to why it would be removed when you load the component, that isn't default behavior. I checked specificly in a clean test project and wasn't redirected or changed. Is it a default route or something else that is special about the routing?

Read about routing with query strings and params in the Angular2 Tutorial at https://angular.io/docs/ts/latest/guide/router.html#!#query-parameters

Check your runtime tag inside the web.config, and verify you have something like this declared:

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
      </dependentAssembly>
.....
</runtime>

string ToHex(const string& s, bool upper_case /* = true */)
{
    ostringstream ret;

    for (string::size_type i = 0; i < s.length(); ++i)
        ret << std::hex << std::setfill('0') << std::setw(2) << (upper_case ? std::uppercase : std::nouppercase) << (int)s[i];

    return ret.str();
}

int FromHex(const string &s) { return strtoul(s.c_str(), NULL, 16); }

Like you I also faced many problems implementing OCR in Android, but after much Googling I found the solution, and it surely is the best example of OCR.

Let me explain using step-by-step guidance.

First, download the source code from https://github.com/rmtheis/tess-two.

Import all three projects. After importing you will get an error. To solve the error you have to create a res folder in the tess-two project

First, just create res folder in tess-two by tess-two->RightClick->new Folder->Name it "res"

After doing this in all three project the error should be gone.

Now download the source code from https://github.com/rmtheis/android-ocr, here you will get best example.

Now you just need to import it into your workspace, but first you have to download android-ndk from this site:

http://developer.android.com/tools/sdk/ndk/index.html i have windows 7 - 32 bit PC so I have download http://dl.google.com/android/ndk/android-ndk-r9-windows-x86.zip this file

Now extract it suppose I have extract it into E:\Software\android-ndk-r9 so I will set this path on Environment Variable

Right Click on MyComputer->Property->Advance-System-Settings->Advance->Environment Variable-> find PATH on second below Box and set like path like below picture

done it

Now open cmd and go to on D:\Android Workspace\tess-two like below

If you have successfully set up environment variable of NDK then just type ndk-build just like above picture than enter you will not get any kind of error and all file will be compiled successfully:

Now download other source code also from https://github.com/rmtheis/tess-two , and extract and import it and give it name OCRTest, like in my PC which is in D:\Android Workspace\OCRTest

Import test-two in this and run OCRTest and run it; you will get the best example of OCR.

W3C CSS Transitions Draft

The completion of a CSS Transition generates a corresponding DOM Event. An event is fired for each property that undergoes a transition. This allows a content developer to perform actions that synchronize with the completion of a transition.

Webkit

To determine when a transition completes, set a JavaScript event listener function for the DOM event that is sent at the end of a transition. The event is an instance of WebKitTransitionEvent, and its type is webkitTransitionEnd.

box.addEventListener( 'webkitTransitionEnd', 
    function( event ) { alert( "Finished transition!" ); }, false );

Mozilla

There is a single event that is fired when transitions complete. In Firefox, the event is transitionend, in Opera, oTransitionEnd, and in WebKit it is webkitTransitionEnd.

Opera

There is one type of transition event available. The oTransitionEnd event occurs at the completion of the transition.

Internet Explorer

The transitionend event occurs at the completion of the transition. If the transition is removed before completion, the event will not fire.

Stack Overflow: How do I normalize CSS3 Transition functions across browsers?

If you absolutely have to add the property to the object, I believe you could cast it as an array, add your property (as a new array key), then cast it back as an object. The only time you run into stdClass objects (I believe) is when you cast an array as an object or when you create a new stdClass object from scratch (and of course when you json_decode() something - silly me for forgetting!).

Instead of:

$foo = new StdClass();
$foo->bar = '1234';

You'd do:

$foo = array('bar' => '1234');
$foo = (object)$foo;

Or if you already had an existing stdClass object:

$foo = (array)$foo;
$foo['bar'] = '1234';
$foo = (object)$foo;

Also as a 1 liner:

$foo = (object) array_merge( (array)$foo, array( 'bar' => '1234' ) );

If you are debugging and wasting time like me, this will give exact details including passwords. :P

mvn help:effective-settings -DshowPasswords=true

For your question as asked

Columns(3).Insert
Range("c1:c4") = Application.Transpose(Array("Loc", "uk", "us", "nj"))

If you had a way of automatically looking up the data (ie matching uk against employer id) then you could do that in VBA

I think simpler (though without a script) assuming the Status column is ColumnS.

Select ColumnS and clear formatting from it. Select entire range to be formatted and Format, Conditional formatting..., Format cells if... Custom formula is and:

=and($S1<>"",search("Complete",$S1)>0)

with fill of choice and Done.

This is not case sensitive (change search to find for that) and will highlight a row where ColumnS contains the likes of Now complete (though also Not yet complete).

Dim f as Range

Set f=ActiveSheet.Cells.Find(...)

If Not f Is Nothing then
    msgbox "Row=" & f.Row & vbcrlf & "Column=" & f.Column
Else
    msgbox "value not found!"
End If

The query below demonstrates use of the package and some of the information you can get.

select sys_context ( 'USERENV', 'DB_NAME' ) db_name,
sys_context ( 'USERENV', 'SESSION_USER' ) user_name,
sys_context ( 'USERENV', 'SERVER_HOST' ) db_host,
sys_context ( 'USERENV', 'HOST' ) user_host
from dual

NOTE: The parameter ‘SERVER_HOST’ is available in 10G only.

Any Oracle User that can connect to the database can run a query against “dual”. No special permissions are required and SYS_CONTEXT provides a greater range of application-specific information than “sys.v$instance”.

require 'net/http'
require 'json'

def create_agent
    uri = URI('http://api.nsa.gov:1337/agent')
    http = Net::HTTP.new(uri.host, uri.port)
    req = Net::HTTP::Post.new(uri.path, 'Content-Type' => 'application/json')
    req.body = {name: 'John Doe', role: 'agent'}.to_json
    res = http.request(req)
    puts "response #{res.body}"
rescue => e
    puts "failed #{e}"
end

You cannot directly see the query result using mysql_query its only fires the query in mysql nothing else.

For getting the result you have to add a lil things in your script like

require_once('db.php');  
 $sql="SELECT * FROM  modul1open WHERE idM1O>=(SELECT FLOOR( MAX( idM1O ) * RAND( ) )  FROM  modul1open) ORDER BY idM1O LIMIT 1";

 $result = mysql_query($sql);
 //echo [$result];
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
    print_r($row);
}

This will give you result;

As realpath is not installed per default on my Linux system, the following works for me:

SCRIPT="$(readlink --canonicalize-existing "$0")"
SCRIPTPATH="$(dirname "$SCRIPT")"

$SCRIPT will contain the real file path to the script and $SCRIPTPATH the real path of the directory containing the script.

Before using this read the comments of this answer.

    int i;
    for(i = 0;i < iLen;i++){

            *(--pEnd) = '\0';
    }
    strcpy(szStr, pStart);
    return szStr;
}

I found I had installed 32-bit Eclipse by mistake, and was trying to use it with a 64-bit JRE, which is why I got this error. To see whether you have 32 or 64 bit Eclipse installed, see this answer: https://stackoverflow.com/a/9578565/191761

Don't update the primary key. It could cause a lot of problems for you keeping your data intact, if you have any other tables referencing it.

Ideally, if you want a unique field that is updateable, create a new field.

the root directory (in PHP) is the directory of the file that is pinged. For example, I go to http://localhost/directory/to/file/index.php, the root directory will be "/dictory/to/file", since it's the one that you've made a web request for.

Yes, it works. Check the below example. Assuming @value is not int

WITH CTE 
AS
(
    SELECT NULL AS test
    UNION
    SELECT '' AS test
    UNION
    SELECT '123' AS test
)

SELECT 
    CASE WHEN isnull(test,'')='' THEN 'empty' ELSE test END AS IS_EMPTY 
FROM CTE

Result :

IS_EMPTY
--------
empty
empty
123

There is an overload with 3 arguments. Html.DropdownList(name, selectList, optionLabel) Update: there was a typo in the below code snippet.

@Html.DropDownList("Cat", new SelectList(ViewBag.Categories,"ID", "CategoryName"), "-Select Category-")

For the validator use

@Html.ValidationMessage("Cat")

Matt's answer is the right one for older Pythons and Kevin's the right answer for newer ones.

If you wish not to copy the function for silentremove, this functionality is exposed in path.py as remove_p:

from path import Path
Path(filename).remove_p()

In the latest version of ggplot2, this can be more easy.

Your ComboBox is trying to bind to bind to GridItem[x].CompanyItems, which doesn't exist.

Your RelativeBinding is close, however it needs to bind to DataContext.CompanyItems because Window.CompanyItems does not exist

Suppose you want to load RegistrationComponent on load and then ConfirmationComponent on some event click on RegistrationComponent.

So in appModule.ts, you can write like this.

RouterModule.forRoot([
      { 
        path: '', 
        redirectTo: 'registration', 
        pathMatch: 'full'
       },
       { 
        path: 'registration', 
        component: RegistrationComponent
       },
      {
        path : 'confirmation',
        component: ConfirmationComponent
      }
    ]) 

OR

RouterModule.forRoot([
       { 
        path: '', 
        component: RegistrationComponent
       },
      {
        path : 'confirmation',
        component: ConfirmationComponent
      }
    ]) 

is also fine. Choose whatever you like.

So =~ is faster but it depends what you want to have as a returned value. If you just want to check if the text contains a regex or not use =~

If you are facing any issues during push ( in windows OS), just remove the cached git account by following the given steps below: 1. Search for Control panel and open the same. 2. Search for Credential Manager and open this. 3. Click on Windows Credentials under Manage your credentials page. 4. Under Generic Credentials click on GitHub. 5. Click on Remove and then confirm by clicking Yes button. 6. Now start pushing the code and you will get GitHub popup to login again and now you are done. Everything will work properly after successful login.

DistCp (distributed copy) is a tool used for copying data between clusters. It uses MapReduce to effect its distribution, error handling and recovery, and reporting. It expands a list of files and directories into input to map tasks, each of which will copy a partition of the files specified in the source list.

Usage: $ hadoop distcp <src> <dst>

example: $ hadoop distcp hdfs://nn1:8020/file1 hdfs://nn2:8020/file2

file1 from nn1 is copied to nn2 with filename file2

Distcp is the best tool as of now. Sqoop is used to copy data from relational database to HDFS and vice versa, but not between HDFS to HDFS.

More info:

• http://hadoop.apache.org/docs/r1.2.1/distcp.html
• http://hadoop.apache.org/docs/r1.2.1/distcp2.html

There are two versions available - runtime performance in distcp2 is more compared to distcp

This will strip all commas from the text and left justify it.

for row in inputfile:
    place = row['your_row_number_here'].strip(', ')

For java 8+, another possible solution (more general, func-style and without aspects) could be to create some utility method accepting code as a parameter

public static <T> T timed (String description, Consumer<String> out, Supplier<T> code) {
    final LocalDateTime start = LocalDateTime.now ();
    T res = code.get ();
    final long execTime = Duration.between (start, LocalDateTime.now ()).toMillis ();
    out.accept (String.format ("%s: %d ms", description, execTime));
    return res;
}

And the calling code could be smth like that:

public static void main (String[] args) throws InterruptedException {
    timed ("Simple example", System.out::println, Timing::myCode);
}

public static Object myCode () {
    try {
        Thread.sleep (1500);
    } catch (InterruptedException e) {
        e.printStackTrace ();
    }
    return null;
}

Use heroku's fork

1. Use the new "heroku fork" command! It will copy all the environment and you have to update the github repo after!

   heroku fork -a sourceapp targetapp
   

2. Clone it local

   git clone [email protected]:youamazingapp.git
   

3. Make a new repo on github and add it

   git remote add origin https://github.com/yourname/your_repo.git
   

4. Push on github

   git push origin master
   

This is an example straight from the docs:

Default values can be implemented by using _replace() to customize a prototype instance:

>>> Account = namedtuple('Account', 'owner balance transaction_count')
>>> default_account = Account('<owner name>', 0.0, 0)
>>> johns_account = default_account._replace(owner='John')
>>> janes_account = default_account._replace(owner='Jane')

So, the OP's example would be:

from collections import namedtuple
Node = namedtuple('Node', 'val left right')
default_node = Node(None, None, None)
example = default_node._replace(val="whut")

However, I like some of the other answers given here better. I just wanted to add this for completeness.

ln [-Ffhinsv] source_file [target_file]

    link, ln -- make links

        -s    Create a symbolic link.

    A symbolic link contains the name of the file to which it is linked. 

    An ln command appeared in Version 1 AT&T UNIX.

lodash and typescript

const clearSubTopics = _.filter(obj.subTopics, topic => (!_.isEqual(topic.subTopicId, 2)));
console.log(clearSubTopics);

Please see this link for more information on setting the text size in code. Basically it says:

public void setTextSize (int unit, float size)

Since: API Level 1 Set the default text size to a given unit and value. See TypedValue for the possible dimension units. Related XML Attributes

android:textSize Parameters

unit The desired dimension unit.
size The desired size in the given units.

As an aside to the solutions here, there are cleaner alternatives if you're using certain development servers.

With Heroku's Foreman, you can create per-project environment variables in a .env file:

ADMIN_PASSOWRD="secret"

With Pow, you can use a .powenv file:

export ADMIN_PASSOWRD="secret"

<%= link_to "http://www.facebook.com/sharer.php?u=" + article_url(article, :text => article.title), :class => "btn btn-primary" do %>   <i class="fa fa-facebook">     Facebook Share    </i> <%end%> 

I am assuming that current_article_url is http://0.0.0.0:4567/link_to_title

If the object was recently created, you can check the Schema Changes History report, within the SQL Server Management Studio, which "provides a history of all committed DDL statement executions within the Database recorded by the default trace":

You then can search for the create statements of the objects. Among all the information displayed, there is the login name of whom executed the DDL statement.

WITH CHECK is indeed the default behaviour however it is good practice to include within your coding.

The alternative behaviour is of course to use WITH NOCHECK, so it is good to explicitly define your intentions. This is often used when you are playing with/modifying/switching inline partitions.

I encounter this issue recently and I tried many things mentioned in this thread and others. I added package reference for "System.Runtime" by nuget package manager, fixed the binding redicts in app.config, and make sure that app.config and package.config have the same version for the assembly. However, the problem persisted.

Finally, I removed the <dependentAssembly> tag for the assembly and the problem dissappeared. So, try removing the following in your app.config.

<dependentAssembly>
    <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.1.0.0" newVersion="4.1.1.0" />
</dependentAssembly>

Edit: After I update .NET framework to 4.7.2, the problem resurfaced. I tried the above trick but it didn't work. After wasting many hours, I realized the problem is occurring because of an old System.Linq reference in app.config. Therefore, either remove or update all Linq references also to get rid of this problem.

Not sure if this is new in Xcode 5 or not, but you can now open the Size Inspector through Interface Builder and set an inset there. That'll prevent you from having to write custom code to do this for you and should drastically increase the speed at which you find the proper offsets.

I Know, I am very late but, May be my answer can help someone. Basically it's very Simple. Here is my Code.

#include<iostream>
#include<windows.h>
using namespace std;
int main()
{
    HANDLE colors=GetStdHandle(STD_OUTPUT_HANDLE);

    string text;
    int k;
    cout<<" Enter your Text : ";
    getline(cin,text);
    for(int i=0;i<text.length();i++)
    {
        k>9 ? k=0 : k++;

        if(k==0)
        {
            SetConsoleTextAttribute(colors,1);
        }else
        {
            SetConsoleTextAttribute(colors,k);
        }
        cout<<text.at(i);
    }
}

OUTPUT

This Image will show you how it works

Note that services and tools for sending emails may be able to inline your CSS for you, allowing CSS in <style> tags to work in Gmail.

For instance, if you're sending emails with MailChimp, your CSS from <style> tags will get inlined automatically by default. With Mandrill, you can enable this functionality (although it's disabled by default for performance reasons) by checking the "Inline CSS Styles in HTML Emails" box in the "Sending Defaults" section of the Settings tab:

This worked for me using sed [Edit: comment below points out sed doesn't support \s]

[^ ]

while

[^\s] 

didn't

# Delete everything except space and 'g'
echo "ghai ghai" | sed "s/[^\sg]//g"
gg

echo "ghai ghai" | sed "s/[^ g]//g"
g g

I have the same problem on my virtual environment after upgrade python installation from 3.6 to 3.7 but only on vent globally pip work fine, to solve it I deactivate and delete my virtual environment after recreate again and now is fine, on venv:

deactivate
rm -rvf venv 

and after recreate the virtual environment. I use mac OS 10.11, and python 3

You can simply do it with train_test_split() method available in Scikit learn:

from sklearn.model_selection import train_test_split 
train, test = train_test_split(X, test_size=0.25, stratify=X['YOUR_COLUMN_LABEL']) 

I have also prepared a short GitHub Gist which shows how stratify option works:

https://gist.github.com/SHi-ON/63839f3a3647051a180cb03af0f7d0d9

If you are writing portable code, the answer is "you can't tell", the good news is that you don't need to. Your protocol should involve writing the size as (eg) "8 octets, big-endian format" (Ideally with a check that the actual size fits in 8 octets.)

LE: I just remembered this was about using Google Maps, so my answer doesn't really answer the initial question, but I hope some people will save hours/days banging their heads on their desks if they have the same issue with Play Game Services.

I too had this incredibly cryptic error. It wasn't anything related to location services for me, but with not properly reading the documentation, more precisely step 3, where it says to add the following to your AndroidManifest.xml:

<meta-data android:name="com.google.android.gms.games.APP_ID"
    android:value="@string/app_id" />

You should obviously also have the following in AndroidManifest.xml

<meta-data android:name="com.google.android.gms.version"
   android:value="@integer/google_play_services_version"/>

I was using the BaseGameActivity they suggest to use when you want to implement game services so I was a bit surprised it didn't work straight away. I did create a dedicated module for a copy of the google-play-services_lib, I did have the latest version of it (4323000 as of writing) and I did set this as a module dependency to my main module (using Android Studio here). But that little line above fixed everything.

I needed either: both -alpha background and -flatten, or -fill.

I made a new PNG with a transparent background and a red dot in the middle.

convert image.png -background green -alpha off green.png failed: it produced an image with black background

convert image.png -background green -alpha background -flatten green.png produced an image with the correct green background.

Of course, with another file that I renamed image.png, it failed to do anything. For that file, I found that the color of the transparent pixels was "#d5d5d5" so I filled that color with green:

convert image.png -fill green -opaque "#d5d5d5" green.png replaced the transparent pixels with the correct green.

Another way to mimic an enum with consistent equality handling (shamelessly adopted from Dave Thomas). Allows open enums (much like symbols) and closed (predefined) enums.

class Enum
  def self.new(values = nil)
    enum = Class.new do
      unless values
        def self.const_missing(name)
          const_set(name, new(name))
        end
      end

      def initialize(name)
        @enum_name = name
      end

      def to_s
        "#{self.class}::#@enum_name"
      end
    end

    if values
      enum.instance_eval do
        values.each { |e| const_set(e, enum.new(e)) }
      end
    end

    enum
  end
end

Genre = Enum.new %w(Gothic Metal) # creates closed enum
Architecture = Enum.new           # creates open enum

Genre::Gothic == Genre::Gothic        # => true
Genre::Gothic != Architecture::Gothic # => true

My pathetic contribution to this dumb problem. In IB set the style to none so you can set the height, then in IB set the class to be a subclass of UITextField that forces the style to be rounded rect.

@interface JLTForcedRoundedRectTextField : UITextField
@end

@implementation JLTForcedRoundedRectTextField
- (void)awakeFromNib
{
    self.borderStyle = UITextBorderStyleRoundedRect;
}
@end

It kept me from having to hack the XIB file or writing style code into my view controller.

This is posted simply if anyone comes looking for this question. Even though its been answered a bit. Some of the replies make it more complex than it needed to be.

For mysql* I used :

if (mysqli_num_rows(
    mysqli_query(
                    $con,"SHOW TABLES LIKE '" . $table . "'")
                ) > 0
        or die ("No table set")
    ){

In PDO I used:

if ($con->query(
                   "SHOW TABLES LIKE '" . $table . "'"
               )->rowCount() > 0
        or die("No table set")
   ){

With this I just push the else condition into or. And for my needs I only simply need die. Though you can set or to other things. Some might prefer the if/ else if/else. Which is then to remove or and then supply if/else if/else.

If you know the order of elements in your Set, you can retrieve them by converting the Set to an Array. Something like this:

Set mySet = MyStorageObject.getMyStringSet();
Object[] myArr = mySet.toArray();
String value1 = myArr[0].toString();
String value2 = myArr[1].toString();

The script below works on all platforms as it's pure Python. It makes use of the pathlib Path, documented here https://docs.python.org/3/library/pathlib.html, to make it work cross-platform. You run it once, restart the kernel and that's it. Inspired by https://medium.com/@arnaud.bertrand/modifying-python-s-search-path-with-pth-files-2a41a4143574. In order to run it it requires administrator privileges since you modify some system files.

from pathlib import Path
to_add=Path(path_of_directory_to_add)
from sys import path

if str(to_add) not in path:
    minLen=999999
    for index,directory in enumerate(path):
        if 'site-packages' in directory and len(directory)<=minLen:
            minLen=len(directory)
            stpi=index
            
    pathSitePckgs=Path(path[stpi])
    with open(str(pathSitePckgs/'current_machine_paths.pth'),'w') as pth_file:
        pth_file.write(str(to_add))

Use JQuery. You need to set-up a click event on your button which will toggle the visibility of your wizard div.

$('#btn').click(function() {
    $('#wizard').toggle();
});

Refer to the JQuery website for more information.

This can also be done without JQuery. Using only standard JavaScript:

<script type="text/javascript">
   function toggle_visibility(id) {
       var e = document.getElementById(id);
       if(e.style.display == 'block')
          e.style.display = 'none';
       else
          e.style.display = 'block';
   }
</script>

Then add onclick="toggle_visibility('id_of_element_to_toggle');" to the button that is used to show and hide the div.

You need CSS to achieve this, e.g.:

#container_2 {
    -webkit-transform: rotate(90deg);
    -moz-transform: rotate(90deg);
    -o-transform: rotate(90deg);
    -ms-transform: rotate(90deg);
    transform: rotate(90deg);
}

Demo:

#container_2 {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 1px solid red;_x000D_
  -webkit-transform: rotate(45deg);_x000D_
  -moz-transform: rotate(45deg);_x000D_
  -o-transform: rotate(45deg);_x000D_
  -ms-transform: rotate(45deg);_x000D_
  transform: rotate(45deg);_x000D_
}

<div id="container_2"></div>

(There's 45 degrees rotation in the demo, so you can see the effect)

Note: The -o- and -moz- prefixes are no longer relevant and probably not required. IE9 requires -ms- and Safari and the Android browser require -webkit-

Update 2018: Vendor prefixes are not needed anymore. Only transform is sufficient. (thanks @rinogo)

This masks the password with a red square, then reverts back to the original colours once the password has been entered.

It doesn't stop the user from using copy/paste to get the password, but if it's more just about stopping someone looking over your shoulder, this is a good quick solution.

Console.Write("Password ");
ConsoleColor origBG = Console.BackgroundColor; // Store original values
ConsoleColor origFG = Console.ForegroundColor;

Console.BackgroundColor = ConsoleColor.Red; // Set the block colour (could be anything)
Console.ForegroundColor = ConsoleColor.Red;

string Password = Console.ReadLine(); // read the password

Console.BackgroundColor= origBG; // revert back to original
Console.ForegroundColor= origFG;

I stumbled across a feature in Chrome that will list out all open named pipes by navigating to "file://.//pipe//"

Since I can't seem to find any reference to this and it has been very helpful to me, I thought I might share.

Here is a helper method to do the job.

First of all you'll need a new Comparator interface, as Comparator doesn't support primitives:

public interface IntComparator{
    public int compare(int a, int b);
}

(You could of course do it with autoboxing / unboxing but I won't go there, that's ugly)

Then, here's a helper method to sort an int array using this comparator:

public static void sort(final int[] data, final IntComparator comparator){
    for(int i = 0; i < data.length + 0; i++){
        for(int j = i; j > 0
            && comparator.compare(data[j - 1], data[j]) > 0; j--){
            final int b = j - 1;
            final int t = data[j];
            data[j] = data[b];
            data[b] = t;
        }
    }
}

And here is some client code. A stupid comparator that sorts all numbers that consist only of the digit '9' to the front (again sorted by size) and then the rest (for whatever good that is):

final int[] data =
    { 4343, 544, 433, 99, 44934343, 9999, 32, 999, 9, 292, 65 };
sort(data, new IntComparator(){

    @Override
    public int compare(final int a, final int b){
        final boolean onlyNinesA = this.onlyNines(a);
        final boolean onlyNinesB = this.onlyNines(b);
        if(onlyNinesA && !onlyNinesB){
            return -1;
        }
        if(onlyNinesB && !onlyNinesA){
            return 1;
        }

        return Integer.valueOf(a).compareTo(Integer.valueOf(b));
    }

    private boolean onlyNines(final int candidate){
        final String str = String.valueOf(candidate);
        boolean nines = true;
        for(int i = 0; i < str.length(); i++){
            if(!(str.charAt(i) == '9')){
                nines = false;
                break;
            }
        }
        return nines;
    }
});

System.out.println(Arrays.toString(data));

Output:

[9, 99, 999, 9999, 32, 65, 292, 433, 544, 4343, 44934343]

The sort code was taken from Arrays.sort(int[]), and I only used the version that is optimized for tiny arrays. For a real implementation you'd probably want to look at the source code of the internal method sort1(int[], offset, length) in the Arrays class.

C99 standard on c >= '0' && c <= '9'

c >= '0' && c <= '9' (mentioned in another answer) works because C99 N1256 standard draft 5.2.1 "Character sets" says:

In both the source and execution basic character sets, the value of each character after 0 in the above list of decimal digits shall be one greater than the value of the previous.

ASCII is not guaranteed however.

You need to iterate through all the enum values in Animal and return the value that matches the description you need.

You can do the following:

IQueryable query = from x in appEntities
             where x.id == 32
             select x;

var sql = ((System.Data.Objects.ObjectQuery)query).ToTraceString();

or in EF6:

var sql = ((System.Data.Entity.Core.Objects.ObjectQuery)query)
            .ToTraceString();

That will give you the SQL that was generated.
