Just because you're not wrapping the entire request body in JSON, doesn't meant it's not RESTful to use multipart/form-data to post both the JSON and the file(s) in a single request:

curl -F "metadata=<metadata.json" -F "[email protected]" http://example.com/add-file

on the server side:

class AddFileResource(Resource):
    def render_POST(self, request):
        metadata = json.loads(request.args['metadata'][0])
        file_body = request.args['file'][0]
        ...

to upload multiple files, it's possible to either use separate "form fields" for each:

curl -F "metadata=<metadata.json" -F "[email protected]" -F "[email protected]" http://example.com/add-file

...in which case the server code will have request.args['file1'][0] and request.args['file2'][0]

or reuse the same one for many:

curl -F "metadata=<metadata.json" -F "[email protected]" -F "[email protected]" http://example.com/add-file

...in which case request.args['files'] will simply be a list of length 2.

or pass multiple files through a single field:

curl -F "metadata=<metadata.json" -F "[email protected],some-other-file.tar.gz" http://example.com/add-file

...in which case request.args['files'] will be a string containing all the files, which you'll have to parse yourself — not sure how to do it, but I'm sure it's not difficult, or better just use the previous approaches.

The difference between @ and < is that @ causes the file to get attached as a file upload, whereas < attaches the contents of the file as a text field.

P.S. Just because I'm using curl as a way to generate the POST requests doesn't mean the exact same HTTP requests couldn't be sent from a programming language such as Python or using any sufficiently capable tool.

The naming convention is part of the well-established JavaBeans specification and is supported by the classes in the java.beans package.

It seem that w3c switched it to font/woff2

I see there is some discussion about the proper mime type. In the link we read:

This document defines a top-level MIME type "font" ...

... the officially defined IANA subtypes such as "application/font-woff" ...

The members of the W3C WebFonts WG believe the use of "application" top-level type is not ideal.

and later

6.5. WOFF 2.0

    Type name:

        font
    Subtype name:

        woff2

So proposition from W3C differs from IANA.

We can see that it also differs from woff type: http://dev.w3.org/webfonts/WOFF/spec/#IMT where we read:

Type name:

    application
Subtype name:

    font-woff

which is

application/font-woff

If you want to have cd functionality (assuming shell=True) and still want to change the directory in terms of the Python script, this code will allow 'cd' commands to work.

import subprocess
import os

def cd(cmd):
    #cmd is expected to be something like "cd [place]"
    cmd = cmd + " && pwd" # add the pwd command to run after, this will get our directory after running cd
    p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, universal_newlines=True) # run our new command
    out = p.stdout.read()
    err = p.stderr.read()
    # read our output
    if out != "":
        print(out)
        os.chdir(out[0:len(out) - 1]) # if we did get a directory, go to there while ignoring the newline 
    if err != "":
        print(err) # if that directory doesn't exist, bash/sh/whatever env will complain for us, so we can just use that
    return

I've a snippet that shows, how to get the spacings of elements with jQuery:

/* messing vertical spaces of block level elements with jQuery in pixels */

console.clear();

var jObj = $('selector');

for(var i = 0, l = jObj.length; i < l; i++) {
  //jObj.eq(i).css('display', 'block');
  console.log('jQuery object:', jObj.eq(i));
  console.log('plain element:', jObj[i]);

  console.log('without spacings                - jObj.eq(i).height():         ', jObj.eq(i).height());
  console.log('with padding                    - jObj[i].clientHeight:        ', jObj[i].clientHeight);
  console.log('with padding and border         - jObj.eq(i).outerHeight():    ', jObj.eq(i).outerHeight());
  console.log('with padding, border and margin - jObj.eq(i).outerHeight(true):', jObj.eq(i).outerHeight(true));
  console.log('total vertical spacing:                                        ', jObj.eq(i).outerHeight(true) - jObj.eq(i).height());
}

Don't forget the easy route:

    static void Main(string[] args)
    {
        var text = File.ReadAllText(@"C:\words.txt");
        File.WriteAllText(@"C:\words.txt", text + "DERP");
    }

$this->db->where('emailsToCampaigns.campaignId !=' , $campaignId);

This should work (which you have tried)

To debug you might place this code just after you execute your query to see what exact SQL it is producing, this might give you clues, you might add that to the question to allow for further help.

$this->db->get();              // your query executing

echo '<pre>';                  // to preserve formatting
die($this->db->last_query());  // halt execution and print last ran query.

str.replace(/^.+?\"|^.|\".+/, '');

This is sometimes bad to use when you wanna select what else to remove between "" and you cannot use it more than twice in one string. All it does is select whatever is not in between "" and replace it with nothing.

Even for me it is a bit confusing, but ill try to explain it. ^.+? (not anything OPTIONAL) till first " then | Or/stop (still researching what it really means) till/at ^. has selected nothing until before the 2nd " using (| stop/at). And select all that comes after with .+.

Just use a funcy library: pip install funcy

import funcy


funcy.flatten([[[[1, 1], 1], 2], 3]) # returns generator
funcy.lflatten([[[[1, 1], 1], 2], 3]) # returns list

You can use try-catch block to check for integer value

for eg:

User inputs in form of string

try
{
   int num=Integer.parseInt("Some String Input");
}
catch(NumberFormatException e)
{
  //If number is not integer,you wil get exception and exception message will be printed
  System.out.println(e.getMessage());
}

-z string True if the string is null (an empty string)

According to mzabriskie on GitHub:

Overall they are very similar. Some benefits of axios:

• Transformers: allow performing transforms on data before a request is made or after a response is received

• Interceptors: allow you to alter the request or response entirely (headers as well). also, perform async operations before a request is made or before Promise settles

• Built-in XSRF protection

please check Browser Support Axios

I think you should use axios.

Swift version

This is the Swift version of David's Objective-C answer. You use the global queue to run things in the background and the main queue to update the UI.

DispatchQueue.global(qos: .background).async {
    
    // Background Thread
    
    DispatchQueue.main.async {
        // Run UI Updates
    }
}

• Compiler : Which convert Human understandable format into machine understandable format
• Linker : Which convert machine understandable format into Operating system understandable format
• Loader : is entity which actually load and runs the program into RAM

Linker & Interpreter are mutually exclusive Interpreter getting code line by line and execute line by line.

There are some issues with the scripts above:

shift "removes" the parameter $1, otherwise, "push" will read it and "misunderstand it".

My tip :

git config --global alias.acpp '!git add -A && branchatu="$(git symbolic-ref HEAD 2>/dev/null)" && branchatu=${branchatu##refs/heads/} && git commit -m "$1" && shift && git pull -u origin $branchatu && git push -u origin $branchatu'

Note: please update the date format accordingly.

Format Date

   __formatDate: function(myDate){
      var ts = moment.utc(myDate);
      return ts.local().format('D-MMM-Y');
   }

Format Time

  __formatTime: function(myDate){
      var ts = moment.utc(myDate);
      return ts.local().format('HH:mm');
  },

See this answer: there is in Ruby 1.9.2, but not in earlier versions. Personally I think rand(8) + 3 is fine, but if you're interested check out the Random class described in the link.

In this case, you might get some differences. Consider a line like:

"foo\tbar "

In this case, if you strip, then you'll get {"foo":"bar"} as the dictionary entry. If you don't strip, you'll get {"foo":"bar "} (note the extra space at the end)

Note that if you use line.split() instead of line.split('\t'), you'll split on every whitespace character and the "striping" will be done during splitting automatically. In other words:

line.strip().split()

is always identical to:

line.split()

but:

line.strip().split(delimiter)

Is not necessarily equivalent to:

line.split(delimiter)

I stumbled in here looking for a similar answer without the "git log" restriction. The answers here didn't give me what I needed but this did so I'll add it in case others find it useful:

git diff --name-only

You can also couple this with standard commit pointers to see what has changed since a particular commit:

git diff --name-only HEAD~3
git diff --name-only develop
git diff --name-only 5890e37..ebbf4c0

This succinctly provides file names only which is great for scripting. For example:

git diff --name-only develop | while read changed_file; do echo "This changed from the develop version: $changed_file"; done

#OR

git diff --name-only develop | xargs tar cvf changes.tar

Old question but this answer might help someone.

If you are trying to display the contents of the container outside of the boundaries of the container, make sure that it doesn't have overflow:hidden, otherwise anything outside of it will be cut off.

Here I propose a way to do this exclusively using the Bootstrap framework built-in functionality.

1. You need to make sure the target div has an ID.
2. Bootstrap has a class "collapse", this will hide your block by default. If you want your div to be collapsible AND be shown by default you need to add "in" class to the collapse. Otherwise the toggle behavior will not work properly.
3. Then, on your hyperlink (also works for buttons), add an href attribute that points to your target div.
4. Finally, add the attribute data-toggle="collapse" to instruct Bootstrap to add an appropriate toggle script to this tag.

Here is a code sample than can be copy-pasted directly on a page that already includes Bootstrap framework (up to version 3.4.1):

<a href="#Foo" class="btn btn-default" data-toggle="collapse">Toggle Foo</a>
<button href="#Bar" class="btn btn-default" data-toggle="collapse">Toggle Bar</button>
<div id="Foo" class="collapse">
    This div (Foo) is hidden by default
</div>
<div id="Bar" class="collapse in">
    This div (Bar) is shown by default and can toggle
</div>

if you are using vector drawables, then you simply need to specify a <corners> element in your drawable definition. I have covered this in a blog post.

If you are using bitmap / 9-patch drawables then you'll need to create the corners with transparency in the bitmap image.

Similar approach which Saeed Zarinfam used but more Java 8 style:)

persons.collect(Collectors.groupingBy(p -> p.getName())).values().stream()
 .map(plans -> plans.stream().findFirst().get())
 .collect(toList());

Change import React from 'react-dom to import React, {Component} from 'react'
And change class Classname extends React.Component to class Classname extends Component
If you are using the latest version of React(16.8.6 as of now).

I had the same problem and solved it by creating an environment variable to be loaded every time I logged in to the production server, and made a mini-guide of the steps to configure it:

I was using Rails 4.1 with Unicorn v4.8.2 and when I tried to deploy my application it didn't start properly and in the unicorn.log file I found this error message:

app error: Missing `secret_key_base` for 'production' environment, set this value in `config/secrets.yml` (RuntimeError)

After some research I found out that Rails 4.1 changed the way to manage the secret_key, so if you read the secrets.yml file located at exampleRailsProject/config/secrets.yml you'll find something like this:

# Do not keep production secrets in the repository,
# instead read values from the environment.
production:
  secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>

This means that Rails recommends you to use an environment variable for the secret_key_base in your production server. In order to solve this error you should follow these steps to create an environment variable for Linux (in my case Ubuntu) in your production server:

1. In the terminal of your production server execute:

   $ RAILS_ENV=production rake secret
   

   This returns a large string with letters and numbers. Copy that, which we will refer to that code as GENERATED_CODE.

2. Login to your server

   • If you login as the root user, find this file and edit it:

     $ vi /etc/profile
     

     Go to the bottom of the file using Shift+G (capital "G") in vi.

     Write your environment variable with the GENERATED_CODE, pressing i to insert in vi. Be sure to be in a new line at the end of the file:

     $ export SECRET_KEY_BASE=GENERATED_CODE
     

     Save the changes and close the file using Esc and then ":x" and Enter for save and exit in vi.

   • But if you login as normal user, let's call it "example_user" for this gist, you will need to find one of these other files:

     $ vi ~/.bash_profile
     $ vi ~/.bash_login
     $ vi ~/.profile
     

     These files are in order of importance, which means that if you have the first file, then you wouldn't need to edit the others. If you found these two files in your directory ~/.bash_profile and ~/.profile you only will have to write in the first one ~/.bash_profile, because Linux will read only this one and the other will be ignored.

     Then we go to the bottom of the file using Shift+G again and write the environment variable with our GENERATED_CODE using i again, and be sure add a new line at the end of the file:

     $ export SECRET_KEY_BASE=GENERATED_CODE
     

     Having written the code, save the changes and close the file using Esc again and ":x" and Enter to save and exit.

3. You can verify that our environment variable is properly set in Linux with this command:

   $ printenv | grep SECRET_KEY_BASE
   

   or with:

   $ echo $SECRET_KEY_BASE
   

   When you execute this command, if everything went ok, it will show you the GENERATED_CODE from before. Finally with all the configuration done you should be able to deploy without problems your Rails application with Unicorn or some other tool.

When you close your shell and login again to the production server you will have this environment variable set and ready to use it.

And that's it! I hope this mini-guide helps you solve this error.

Disclaimer: I'm not a Linux or Rails guru, so if you find something wrong or any error I will be glad to fix it.

I have used a different USB cable and it started working. This is weird because the USB cable (which was not detected in android studio) was charging the phone. This made me feel like there was a problem on my Mac.

However changing the cable worked for me. Just check this option as well if you got stuck with this problem.

Console.Writeline() shows up in the debug output (Debug => Windows => Output).

That is how I did it and it worked exactly as you asked for inside a RelativeLayout:

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/relativelayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ImageView
        android:id="@+id/myImageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/myImageSouce" />

    <TextView
        android:id="@+id/myImageViewText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@id/myImageView"
        android:layout_alignTop="@id/myImageView"
        android:layout_alignRight="@id/myImageView"
        android:layout_alignBottom="@id/myImageView"
        android:layout_margin="1dp"
        android:gravity="center"
        android:text="Hello"
        android:textColor="#000000" />

</RelativeLayout>

Serialization is taking a "live" object in memory and converting it to a format that can be stored somewhere (eg. in memory, on disk) and later "deserialized" back into a live object.

Try this:-

ALTER TABLE <TABLE NAME to be moved> MOVE TABLESPACE <destination TABLESPACE NAME>

Very nice suggestion from IVAN in comments so thought to add in my answer

Note: this will invalidate all table's indexes. So this command is usually followed by

alter index <owner>."<index_name>" rebuild;

You probably want git checkout master, or git checkout [branchname].

$assoc = @{
    Id = 34
    FirstName = "John"
    LastName = "Doe"
    Owner = "Wife"
}

$assocId = $assoc.Id
$assocFN = $assoc.FirstName
$assocLN = $assoc.LastName
$assocName = $assocFN, $assocLN -Join " "
$assocOwner = $assoc.Owner

$assocJoin = $assocId, $assocName, $assocOwner -join " - "
$assocJoin
#Output = 34 - John Doe - Wife

The most compatible way of doing this is using tput to discover the right sequences to send to the terminal:

bold=$(tput bold)
normal=$(tput sgr0)

then you can use the variables $bold and $normal to format things:

echo "this is ${bold}bold${normal} but this isn't"

gives

this is bold but this isn't

You could use the LINQ select clause and reference the property that relates to your Name column.

As others pointed out, the only difference is that require throws a fatal error, and include - a catchable warning. As for which one to use, my advice is to stick to include. Why? because you can catch a warning and produce a meaningful feedback to end users. Consider

  // Example 1.
  // users see a standard php error message or a blank screen
  // depending on your display_errors setting
  require 'not_there'; 


  // Example 2.
  // users see a meaningful error message
  try {
      include 'not_there';
  } catch(Exception $e) {
     echo "something strange happened!";
  }

NB: for example 2 to work you need to install an errors-to-exceptions handler, as described here http://www.php.net/manual/en/class.errorexception.php

  function exception_error_handler($errno, $errstr, $errfile, $errline ) {
     throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
  }
  set_error_handler("exception_error_handler");   

The simple solution you need to follow is

import { DomSanitizer } from '@angular/platform-browser';

constructor(private sanitizer: DomSanitizer){}

transformYourHtml(htmlTextWithStyle) {
    return this.sanitizer.bypassSecurityTrustHtml(htmlTextWithStyle);
}

MDN suggests that there's a much cleaner way of doing this in modern browsers:

// Assuming we're listening for e.g. a 'change' event on `element`

// Create a new 'change' event
var event = new Event('change');

// Dispatch it.
element.dispatchEvent(event);

Another way of doing it is take the current date convert it into long just take the last 4 digits. There is a high probability that the number will be unique.

    long time = new Date().getTime();
    String tmpStr = String.valueOf(time);
    String last4Str = tmpStr.substring(tmpStr.length() -5);
    int notificationId = Integer.valueOf(last4Str);

for all views (you need dba privileges for this query)

select view_name from dba_views

for all accessible views (accessible by logged user)

select view_name from all_views

for views owned by logged user

select view_name from user_views

Another solution, it covered the problem I had with clicking descendants of the popover:

$(document).mouseup(function (e) {
    // The target is not popover or popover descendants
    if (!$(".popover").is(e.target) && 0 === $(".popover").has(e.target).length) {
        $("[data-toggle=popover]").popover('hide');
    }
});

With Git 2.25 (Q1 2020), you can modify it.
See "Git submodule url changed" and the new command

git submodule set-url [--] <path> <newurl>

Original answer (May 2009, ten years ago)

Actually, a patch has been submitted in April 2009 to clarify gitmodule role.

So now the gitmodule documentation does not yet include:

The .gitmodules file, located in the top-level directory of a git working tree, is a text file with a syntax matching the requirements -of linkgit:git-config1.
[NEW]:
As this file is managed by Git, it tracks the +records of a project's submodules.
Information stored in this file is used as a hint to prime the authoritative version of the record stored in the project configuration file.
User specific record changes (e.g. to account for differences in submodule URLs due to networking situations) should be made to the configuration file, while record changes to be propagated (e.g. +due to a relocation of the submodule source) should be made to this file.

That pretty much confirm Jim's answer.

If you follow this git submodule tutorial, you see you need a "git submodule init" to add the submodule repository URLs to .git/config.

"git submodule sync" has been added in August 2008 precisely to make that task easier when URL changes (especially if the number of submodules is important).
The associate script with that command is straightforward enough:

module_list "$@" |
while read mode sha1 stage path
do
    name=$(module_name "$path")
    url=$(git config -f .gitmodules --get submodule."$name".url)
    if test -e "$path"/.git
    then
    (
        unset GIT_DIR
        cd "$path"
        remote=$(get_default_remote)
        say "Synchronizing submodule url for '$name'"
        git config remote."$remote".url "$url"
    )
    fi
done

The goal remains: git config remote."$remote".url "$url"

• contentType is the HTTP header sent to the server, specifying a particular format.
  Example: I'm sending JSON or XML
• dataType is you telling jQuery what kind of response to expect.
  Expecting JSON, or XML, or HTML, etc. The default is for jQuery to try and figure it out.

The $.ajax() documentation has full descriptions of these as well.

In your particular case, the first is asking for the response to be in UTF-8, the second doesn't care. Also the first is treating the response as a JavaScript object, the second is going to treat it as a string.

So the first would be:

success: function(data) {
  // get data, e.g. data.title;
}

The second:

success: function(data) {
  alert("Here's lots of data, just a string: " + data);
}

There are Linq extension methods for DataTable.

Add reference to: System.Data.DataSetExtensions.dll

Then include the namespace: using System.Data.DataSetExtensions

Finally you can use Linq extensions on DataSet and DataTables:

var matches = myDataSet.Tables.First().Where(dr=>dr.Field<int>("id") == 1);

On .Net 2.0 you can still add generic method:

public static List<T> ConvertRowsToList<T>( DataTable input, Convert<DataRow, T> conversion) {
    List<T> retval = new List<T>()
    foreach(DataRow dr in input.Rows)
        retval.Add( conversion(dr) );

    return retval;
}

Presuming that you don't want to remove internal spaces:

def normalize_space(s):
    """Return s stripped of leading/trailing whitespace
    and with internal runs of whitespace replaced by a single SPACE"""
    # This should be a str method :-(
    return ' '.join(s.split())

replacement = [normalize_space(i) for i in hello]

One-liner

str = str.replace(/^,/, '');

I'll be back.

You can always use Sharepoint Solution Generator to create a project and edit in VS2008.

You can find the Generator along with Sharepoint Developer tools.

A bit safer version than using xargs, also not recursive: ls -p | grep -v '/$' | grep '\.pdf$' | while read file; do rm "$file"; done

Filtering our directories here is a bit unnecessary as 'rm' won't delete it anyway, and it can be removed for simplicity, but why run something that will definitely return error?

First of all, you should be using json.loads, not json.dumps. loads converts JSON source text to a Python value, while dumps goes the other way.

After you fix that, based on the JSON snippet at the top of your question, readable_json will be a list, and so readable_json['firstName'] is meaningless. The correct way to get the 'firstName' field of every element of a list is to eliminate the playerstuff = readable_json['firstName'] line and change for i in playerstuff: to for i in readable_json:.

On macOS, you can use DTrace instead. The "Instruments" app is a nice GUI for that, it comes with XCode afaik.

while(!feof(fp))
{
  ch = fgetc(fp);
  if(ch == '\n')
  {
    lines++;
  }
}

But please note: Why is “while ( !feof (file) )” always wrong?.

If you are just getting started with a new project then I would suggest that you use PDO instead of the old odbc_exec() approach. Here is a simple example:

<?php
$bits = 8 * PHP_INT_SIZE;
echo "(Info: This script is running as $bits-bit.)\r\n\r\n";

$connStr = 
        'odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};' .
        'Dbq=C:\\Users\\Gord\\Desktop\\foo.accdb;';

$dbh = new PDO($connStr);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$sql = 
        "SELECT AgentName FROM Agents " .
        "WHERE ID < ? AND AgentName <> ?";
$sth = $dbh->prepare($sql);

// query parameter value(s)
$params = array(
        5,
        'Homer'
        );

$sth->execute($params);

while ($row = $sth->fetch()) {
    echo $row['AgentName'] . "\r\n";
}

NOTE: The above approach is sufficient if you do not need to support Unicode characters above U+00FF. If you do need to support such characters then neither PDO_ODBC nor the old odbc_ functions will work; you'll need to use the solution described in this answer.

I used this for a similar problem:

'catherine mc-nulty joséphina'.capitalize.gsub(/(\s+\w)/) { |stuff| stuff.upcase }

This handles the following weird cases I saw trying the previous answers:

• non-word characters like -
• accented characters common in names like é
• capital characters in the middle of the string

Hope this will assist anyone having the same error while importing CSV data into related tables. In my case the parent table was OK, but I got the error while importing data to the child table containing the foreign key. After temporarily removing the foregn key constraint on the child table, I managed to import the data and was suprised to find some of the values in the FK column having values of 0 (obviously this had been causing the error since the parent table did not have such values in its PK column). The cause was that, the data in my CSV column preceeding the FK column contained commas (which I was using as a field delimeter). Changing the delimeter for my CSV file solved the problem.

I needed to know this to tell a user what to add to their host machine's host file. This works for me inside vagrant using just bash:

external_ip=$(cat /vagrant/config.yml | grep vagrant_ip | cut -d' ' -f2 | xargs)
echo -e "# Add this line to your host file:\n${external_ip}     host.vagrant.vm"

I wanted something where I have access to base64 value to store into a list and for me adding event listener worked. You just need the FileReader which will read the image blob and return the base64 in the result.

createImageFromBlob(image: Blob) {
    const reader = new FileReader();
    const supportedImages = []; // you can also refer to some global variable
    reader.addEventListener(
      'load',
      () => {
        // reader.result will have the required base64 image
        const base64data = reader.result;
        supportedImages.push(base64data); // this can be a reference to global variable and store the value into that global list so as to use it in the other part
      },
      false
    );
    // The readAsDataURL method is used to read the contents of the specified Blob or File.
    if (image) {
      reader.readAsDataURL(image);
    }
 }

Final part is the readAsDataURL which is very important is being used to read the content of the specified Blob

@Anachronist is closest here, @Simone not far off. The caveat with percentage padding on an element is that it's based on its parent's width, so if different to your container, the proportions will be off.

The most reliable, simplest answer is:

I found a solution in Apache Cordova source code. They implement like this:

var resolvedPromise = typeof Promise == 'undefined' ? null : Promise.resolve();
var nextTick = resolvedPromise ? function(fn) { resolvedPromise.then(fn); } : function(fn) { setTimeout(fn); };

Simple implementation, but smart way.

Over the Android 4.4, use Promise. For older browsers, use setTimeout()

Usage:

nextTick(function() {
  // your code
});

After inserting this trick code, all warning messages are gone.

If $a is the array that's passed, $a[76][0]['id'] should give '76' and $a[76][1]['id'] should give '81', but I can't test as I don't have PHP installed on this machine.

In case you're using Maven I have a great solution for you:

1. Edit your pom.xml file to include following lines:

   <profiles>
       <profile>
           <id>linux</id>
           <activation>
               <os>
                   <family>unix</family>
               </os>
           </activation>
           <properties>
               <logDirectory>/var/log/tomcat6</logDirectory>
           </properties>
       </profile>
       <profile>
           <id>windows</id>
           <activation>
               <os>
                   <family>windows</family>
               </os>
           </activation>
           <properties>
               <logDirectory>${catalina.home}/logs</logDirectory>
           </properties>
       </profile>
   </profiles>
   

   Here you define logDirectory property specifically to OS family.

2. Use already defined logDirectory property in log4j.properties file:

   log4j.appender.FILE=org.apache.log4j.RollingFileAppender
   log4j.appender.FILE.File=${logDirectory}/mylog.log
   log4j.appender.FILE.MaxFileSize=30MB
   log4j.appender.FILE.MaxBackupIndex=10
   log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
   log4j.appender.FILE.layout.ConversionPattern=%d{ISO8601} [%x] %-5p [%t] [%c{1}] %m%n
   

3. That's it!

P.S.: I'm sure this can be achieved using Ant but unfortunately I don't have enough experience with it.

To create a spreadsheet and format a cell using POI, see the Working with Fonts example, and use:

font.setBoldweight(Font.BOLDWEIGHT_BOLD);

POI works very well. There are some things you can't do (e.g. create VBA macros), but it'll read/write spreadsheets with macros, so you can create a suitable template sheet, read it and manipulate it with POI, and then write it out.

Select the body tab and select application/json in the Content-Type drop-down and add a body like this:

{
  "Username":"ABC",
  "Password":"ABC"
}

In order to export out the VAR variable first the most logical and seems working way is to source the variable:

. ./export.bash

or

source ./export.bash

Now when echoing from main shell it works

 echo $VAR
HELLO, VARABLE

We will now reset VAR

export VAR=""
echo $VAR

Now we will execute a script to source the variable then unset it :

./test-export.sh 
HELLO, VARABLE
--
.

the code: cat test-export.sh

    #!/bin/bash
    # Source env variable
    source ./export.bash

    # echo out the variable in test script
    echo $VAR

    # unset the variable 
    unset VAR
    # echo a few dotted lines
    echo "---"
    # now return VAR which is blank
    echo $VAR

Here is one way

PLEASE NOTE: The exports are limited to the script that execute the exports in your main console - so as far as a cron job I would add it like the console like below... for the command part still questionable: here is how you would run in from your shell:

On your command prompt (so long as the export.bash has multiple echo values)

IFS=$'\n'; for entries in $(./export.bash); do  export $entries;  done; ./v1.sh 
HELLO THERE
HI THERE

cat v1.sh

#!/bin/bash
echo $VAR
echo $VAR1

Now so long as this is for your usage - you could make the variables available for your scripts at any time by doing a bash alias like this:

myvars ./v1.sh
HELLO THERE
HI THERE

echo $VAR

.

add this to your .bashrc

function myvars() { 
    IFS=$'\n'; 
    for entries in $(./export.bash); do  export $entries;  done; 

    "$@"; 

    for entries in $(./export.bash); do variable=$(echo $entries|awk -F"=" '{print $1}'); unset $variable;
done

}

source your bashrc file and you can do like above any time ...

Anyhow back to the rest of it..

This has made it available globally then executed the script..

simply echo it out then run export on the echo !

cat export.bash

#!/bin/bash
echo "VAR=HELLO THERE"

Now within script or your console run:

 export "$(./export.bash)"

Try:

echo $VAR
HELLO THERE

Multiple values so long as you know what you are expecting in another script using above method:

cat export.bash

#!/bin/bash
echo "VAR=HELLO THERE"
echo "VAR1=HI THERE"

cat test-export.sh

#!/bin/bash

IFS=$'\n'
for entries in $(./export.bash); do
   export $entries
done

echo "round 1"
echo $VAR
echo $VAR1

for entries in $(./export.bash); do
     variable=$(echo $entries|awk -F"=" '{print $1}');
     unset $variable
done

echo "round 2"
echo $VAR
echo $VAR1

Now the results

 ./test-export.sh 
round 1
HELLO THERE
HI THERE
round 2


.

and the final final update to auto assign read the VARIABLES:

./test-export.sh 
Round 0 - Export out then find variable name - 
Set current variable to the variable exported then echo its value
$VAR has value of HELLO THERE
$VAR1 has value of HI THERE
round 1 - we know what was exported and we will echo out known variables
HELLO THERE
HI THERE
Round 2 - We will just return the variable names and unset them 
round 3 - Now we get nothing back

The script: cat test-export.sh

#!/bin/bash

IFS=$'\n'
echo "Round 0 - Export out then find variable name - "
echo "Set current variable to the variable exported then echo its value"
for entries in $(./export.bash); do
 variable=$(echo $entries|awk -F"=" '{print $1}');
 export $entries
 eval current_variable=\$$variable
 echo "\$$variable has value of $current_variable"
done


echo "round 1 - we know what was exported and we will echo out known variables"
echo $VAR
echo $VAR1

echo "Round 2 - We will just return the variable names and unset them "
for entries in $(./export.bash); do
 variable=$(echo $entries|awk -F"=" '{print $1}');
 unset $variable
done

echo "round 3 - Now we get nothing back"
echo $VAR
echo $VAR1

With this

npm install --save core-js@^3

you now get the error

"core-js@<3 is no longer maintained and not recommended for usage due to the number of
issues. Please, upgrade your dependencies to the actual version of core-js@3"

so you might want to instead try

npm install --save core-js@3

if you're reading this post June 9 2020.

npm install installs all modules that are listed on package.json file and their dependencies.

npm update updates all packages in the node_modules directory and their dependencies.

npm install express installs only the express module and its dependencies.

npm update express updates express module (starting with [email protected], it doesn't update its dependencies).

So updates are for when you already have the module and wish to get the new version.

Here you go:

DECLARE
BEGIN
  dbms_output.enable(NULL); -- Disables the limit of DBMS
  -- Your print here !
END;

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

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

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

You can merge multiple modules in one rootModule , and assign that module as ng-app to a superior element ex: body tag.

code ex:

    <!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<script src="namesController.js"></script>
<script src="myController.js"></script>
<script>var rootApp = angular.module('rootApp', ['myApp1','myApp2'])</script>
<body ng-app="rootApp">

<div ng-app="myApp1" ng-controller="myCtrl" >
First Name: <input type="text" ng-model="firstName"><br>
Last Name: <input type="text" ng-model="lastName"><br>
<br>
Full Name: {{firstName + " " + lastName}}
</div>

<div ng-app="myApp2" ng-controller="namesCtrl">
<ul>
  <li ng-bind="first">{{first}}
  </li>
</ul>
</div>

</body>
</html>

The best way in my eyes is to use the concat() method provided by the String class itself.

The useage would, in your case, look like this:

String myConcatedString = cursor.getString(numcol).concat('-').
       concat(cursor.getString(cursor.getColumnIndexOrThrow(db.KEY_DESTINATIE)));

First convert it to std::wstring:

std::wstring widestr = std::wstring(str.begin(), str.end());

Then get the C string:

const wchar_t* widecstr = widestr.c_str();

This only works for ASCII strings, but it will not work if the underlying string is UTF-8 encoded. Using a conversion routine like MultiByteToWideChar() ensures that this scenario is handled properly.

This is not memory address This is classname@hashcode
Which is the default implementation of Object.toString()

public String toString() {
    return getClass().getName() + "@" + Integer.toHexString(hashCode());
}

where

Class name = full qualified name or absolute name (ie package name followed by class name) hashcode = hexadecimal format (System.identityHashCode(obj) or obj.hashCode() will give you hashcode in decimal format).

Hint:
The confusion root cause is that the default implementation of Object.hashCode() use the internal address of the object into an integer

This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.

And of course, some classes can override both default implementations either for toString() or hashCode()

If you need the default implementation value of hashcode() for a object which overriding it,
You can use the following method System.identityHashCode(Object x)

If you need to do it dynamically in the browser using javascript, here is an example...

<img id=graph alt="" 
  src="http://www.kitco.com/images/live/gold.gif" 
  />

<script language="javascript" type="text/javascript">
    var d = new Date(); 
    document.getElementById("graph").src = 
      "http://www.kitco.com/images/live/gold.gif?ver=" + 
       d.getTime();
</script>

You need to install it first. Create a new Dockerfile, and install wget in it:

FROM ubuntu:14.04
RUN  apt-get update \
  && apt-get install -y wget \
  && rm -rf /var/lib/apt/lists/*

Then, build that image:

docker build -t my-ubuntu .

Finally, run it:

docker run my-ubuntu wget https://downloads-packages.s3.amazonaws.com/ubuntu-14.04/gitlab_7.8.2-omnibus.1-1_amd64.deb

HTML 4 does not make it explicit. The current HTML5 working draft specifies that the first submit button must be the default:

A form element's default button is the first submit button in tree order whose form owner is that form element.

If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.

Normal assignment (=) is not possible inside a lambda expression, although it is possible to perform various tricks with setattr and friends.

Solving your problem, however, is actually quite simple:

input = [Object(name=""), Object(name="fake_name"), Object(name="")]
output = filter(
    lambda o, _seen=set():
        not (not o and o in _seen or _seen.add(o)),
    input
    )

which will give you

[Object(Object(name=''), name='fake_name')]

As you can see, it's keeping the first blank instance instead of the last. If you need the last instead, reverse the list going in to filter, and reverse the list coming out of filter:

output = filter(
    lambda o, _seen=set():
        not (not o and o in _seen or _seen.add(o)),
    input[::-1]
    )[::-1]

which will give you

[Object(name='fake_name'), Object(name='')]

One thing to be aware of: in order for this to work with arbitrary objects, those objects must properly implement __eq__ and __hash__ as explained here.

There are some equivalents of constructors for when the zero values can't make sensible default values or for when some parameter is necessary for the struct initialization.

Supposing you have a struct like this :

type Thing struct {
    Name  string
    Num   int
}

then, if the zero values aren't fitting, you would typically construct an instance with a NewThing function returning a pointer :

func NewThing(someParameter string) *Thing {
    p := new(Thing)
    p.Name = someParameter
    p.Num = 33 // <- a very sensible default value
    return p
}

When your struct is simple enough, you can use this condensed construct :

func NewThing(someParameter string) *Thing {
    return &Thing{someParameter, 33}
}

If you don't want to return a pointer, then a practice is to call the function makeThing instead of NewThing :

func makeThing(name string) Thing {
    return Thing{name, 33}
}

Reference : Allocation with new in Effective Go.

There's now a simpler way with .NET Standard or .NET Core:

var client = new HttpClient();
var response = await client.PostAsync(uri, myRequestObject, new JsonMediaTypeFormatter());

NOTE: In order to use the JsonMediaTypeFormatter class, you will need to install the Microsoft.AspNet.WebApi.Client NuGet package, which can be installed directly, or via another such as Microsoft.AspNetCore.App.

Using this signature of HttpClient.PostAsync, you can pass in any object and the JsonMediaTypeFormatter will automatically take care of serialization etc.

With the response, you can use HttpContent.ReadAsAsync<T> to deserialize the response content to the type that you are expecting:

var responseObject = await response.Content.ReadAsAsync<MyResponseType>();

There is definitely a way to do this -- use X() macros. These macros use the C preprocessor to construct enums, arrays and code blocks from a list of source data. You only need to add new items to the #define containing the X() macro. The switch statement would expand automatically.

Your example can be written as follows:

 // Source data -- Enum, String
 #define X_NUMBERS \
    X(ONE,   "one") \
    X(TWO,   "two") \
    X(THREE, "three")

 ...

 // Use preprocessor to create the Enum
 typedef enum {
  #define X(Enum, String)       Enum,
   X_NUMBERS
  #undef X
 } Numbers;

 ...

 // Use Preprocessor to expand data into switch statement cases
 switch(num)
 {
 #define X(Enum, String) \
     case Enum:  strcpy(num_str, String); break;
 X_NUMBERS
 #undef X

     default: return 0; break;
 }
 return 1;

There are more efficient ways (i.e. using X Macros to create an string array and enum index), but this is the simplest demo.

I'm not sure if this is going to help, but even i faced the exact same problem very recently with oozie-4.2.0 version. After reading through the above answers i have just added the maven option through command line and it worked for me. So, just sharing here.

If you already have a table pre_loaded_tbl with some data. You can use a trick to load the data into your table with following query

INSERT INTO TABLE tweet_table 
  SELECT  "my_data" AS my_column 
    FROM   pre_loaded_tbl 
   LIMIT   5;

Also please note that "my_data" is independent of any data in the pre_loaded_tbl. You can select any data and write any column name (here my_data and my_column). Hive does not require it to have same column name. However structure of select statement should be same as that of your tweet_table. You can use limit to determine how many times you can insert into the tweet_table.

However if you haven't' created any table, you will have to load the data using file copy or load data commands in above answers.

The capitalization is wrong, and you have an extra argument.

Do this instead:

$('img#thumb').removeAttr('id');

For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.

I've also found it useful to access object attributes where the attribute names vary by some iterator. For example, I have used the pattern below for a set of time periods: hour, day, month.

$periods=array('hour', 'day', 'month');
foreach ($periods as $period)
{
    $this->{'value_'.$period}=1;
}

This same pattern can also be used to access class methods. Just build up the method name in the same manner, using strings and string variables.

You could easily argue to just use an array for the value storage by period. If this application were PHP only, I would agree. I use this pattern when the class attributes map to fields in a database table. While it is possible to store arrays in a database using serialization, it is inefficient, and pointless if the individual fields must be indexed. I often add an array of the field names, keyed by the iterator, for the best of both worlds.

class timevalues
{
                             // Database table values:
    public $value_hour;      // maps to values.value_hour
    public $value_day;       // maps to values.value_day
    public $value_month;     // maps to values.value_month
    public $values=array();

    public function __construct()
    {
        $this->value_hour=0;
        $this->value_day=0;
        $this->value_month=0;
        $this->values=array(
            'hour'=>$this->value_hour,
            'day'=>$this->value_day,
            'month'=>$this->value_month,
        );
    }
}

When you restore backup, Make sure to try with the same username for the old one and the new one.

you can also use:

var path = System.Web.Hosting.HostingEnvironment.MapPath("~/App_Data/myfile.txt")

if

var path = Server.MapPath("~/App_Data");
var fullpath = Path.Combine(path , "myfile.txt");

is inaccessible

If you mean by newline the newline character it is \n and \r is the carrier return character, but if you mean by newline the line ending then it depends on the operating system: DOS uses carriage return and line feed ("\r\n") as a line ending, which Unix uses just line feed ("\n")

Use delegate and event.target. delegate takes advantage of the event bubbling by letting one element listen for, and handle, events on child elements. target is the jQ-normalized property of the event object representing the object from which the event originated.

$(document).delegate('*', 'click', function (event) {
    // event.target is the element
    // $(event.target).text() gets its text
});

May not be the exactly same problem. but there is a nice article on the same line Here

In the simple case you can do:

var user = cnn.Query<User>("spGetUser", new {Id = 1}, 
        commandType: CommandType.StoredProcedure).First();

If you want something more fancy, you can do:

 var p = new DynamicParameters();
 p.Add("@a", 11);
 p.Add("@b", dbType: DbType.Int32, direction: ParameterDirection.Output);
 p.Add("@c", dbType: DbType.Int32, direction: ParameterDirection.ReturnValue);

 cnn.Execute("spMagicProc", p, commandType: CommandType.StoredProcedure); 

 int b = p.Get<int>("@b");
 int c = p.Get<int>("@c"); 

Additionally you can use exec in a batch, but that is more clunky.

MySQLdb will not raise an exception if the result set is empty. Additionally cursor.execute() function will return a long value which is number of rows in the fetched result set. So if you want to check for empty results, your code can be re-written as

rows_count = cursor.execute(query_sql)
if rows_count > 0:
     rs = cursor.fetchall()
else:
     // handle empty result set

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

also works. First create a JFrame called frame, then add this code underneath.

    db      0x55,0x56,0x57      ; three bytes in succession

    dt      1.234567e20         ; extended-precision float

DT does not accept numeric constants as operands, and DDQ does not accept float constants as operands. Any size larger than DD does not accept strings as operands.

If you don't want to mess with arrays' sizes, just use the magic of string concatenation:

byte[] c = (new String(a, "l1") + new String(b, "l1")).getBytes("l1");

Or define somewhere in your code

// concatenation charset
static final java.nio.charset.Charset cch = java.nio.charset.StandardCharsets.ISO_8859_1;

and use

byte[] c = (new String(a, cch) + new String(b, cch)).getBytes(cch);

This, of course, also works with more than two string concatenations using the + addition operator.

Both "l1" and ISO_8859_1 indicate the Western Latin 1 character set that encodes each character as a single byte. As no multi-byte translations are performed the characters in the string will have the same values as the bytes (except that they will always be interpreted as positive values, as char is unsigned). At least for the Oracle provided runtime, any byte will therefore be correctly "decoded" and then "encoded" again.

Beware that strings do expand the byte array considerately, requiring additional memory. Strings may also be interned and will therefore not easy be removed. Strings are also immutable, so the values inside them cannot be destroyed. You should therefore not concatenate sensitive arrays this way nor should you use this method for larger byte arrays. Giving a clear indication of what you are doing would also be required, as this method of array concatenation is not a common solution.

In my experience, I always just use an external program to generate the graph (mathematica, gnuplot, matlab, etc.) and export the graph as a pdf or eps file. Then I include it into the document with includegraphics.

As a variation on the accepted answer you could also use the change_column_default method in your migrations:

def up
  change_column_default :profiles, :show_attribute, true
end

def down
  change_column_default :profiles, :show_attribute, nil
end

Rails API-docs

Wikipedia (or rather, the community on Wikipedia) keeps a pretty good up-to-date list here.

• Most browsers are on 1.5 (though they have features of later versions)
• Mozilla progresses with every dot release (they maintain the standard so that's not surprising)
• Firefox 4 is on JavaScript 1.8.5
• The other big off-the-beaten-path one is IE9 - it implements ECMAScript 5, but doesn't implement all the features of JavaScript 1.8.5 (not sure what they're calling this version of JScript, engine codenamed Chakra, yet).

For me put variable before calling did the trick:

OPENSSL_CONF=/usr/ssl/openssl.cnf openssl req -new -x509 -key privatekey.pem -out publickey.cer -days 365

If you want to use a format that allows you to keep the number like your entry this format works for me: "# \\%"

Message Digest (hash) is byte[] in byte[] out

A message digest is defined as a function that takes a raw byte array and returns a raw byte array (aka byte[]). For example SHA-1 (Secure Hash Algorithm 1) has a digest size of 160 bit or 20 byte. Raw byte arrays cannot usually be interpreted as character encodings like UTF-8, because not every byte in every order is an legal that encoding. So converting them to a String with:

new String(md.digest(subject), StandardCharsets.UTF_8)

might create some illegal sequences or has code-pointers to undefined Unicode mappings:

[?a?????%l?3~??.

Binary-to-text Encoding

For that binary-to-text encoding is used. With hashes, the one that is used most is the HEX encoding or Base16. Basically a byte can have the value from 0 to 255 (or -128 to 127 signed) which is equivalent to the HEX representation of 0x00-0xFF. Therefore hex will double the required length of the output, that means a 20 byte output will create a 40 character long hex string, e.g.:

2fd4e1c67a2d28fced849ee1bb76e7391b93eb12

Note that it is not required to use hex encoding. You could also use something like base64. Hex is often preferred because it is easier readable by humans and has a defined output length without the need for padding.

You can convert a byte array to hex with JDK functionality alone:

new BigInteger(1, token).toString(16)

Note however that BigInteger will interpret given byte array as number and not as a byte string. That means leading zeros will not be outputted and the resulting string may be shorter than 40 chars.

Using Libraries to Encode to HEX

You could now copy and paste an untested byte-to-hex method from Stack Overflow or use massive dependencies like Guava.

To have a go-to solution for most byte related issues I implemented a utility to handle these cases: bytes-java (Github)

To convert your message digest byte array you could just do

String hex = Bytes.wrap(md.digest(subject)).encodeHex();

or you could just use the built-in hash feature

String hex =  Bytes.from(subject).hashSha1().encodeHex();

$("#element").css({ display: "none" });

At first I tried to remove inline style in css, but it does not work and new style like display: none will be overwritten. But in JQuery it works like this.

Try to do this:

getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setDisplayShowTitleEnabled(false);

and if you made your custom toolbar (which i presume you did) then you can use the simplest way possible to do this:

toolbarTitle = (TextView)findViewById(R.id.toolbar_title);
toolbarSubTitle = (TextView)findViewById(R.id.toolbar_subtitle);
toolbarTitle.setText("Title");
toolbarSubTitle.setText("Subtitle");

Same goes for any other views you put in your toolbar. Hope it helps.

For me I had issues with history and location... As the accepted answer using window before history and location (i.e) window.history and window.location solved mine

I use the following function to convert data between int, hex and bytes.

def bytes2int(str):
 return int(str.encode('hex'), 16)

def bytes2hex(str):
 return '0x'+str.encode('hex')

def int2bytes(i):
 h = int2hex(i)
 return hex2bytes(h)

def int2hex(i):
 return hex(i)

def hex2int(h):
 if len(h) > 1 and h[0:2] == '0x':
  h = h[2:]

 if len(h) % 2:
  h = "0" + h

 return int(h, 16)

def hex2bytes(h):
 if len(h) > 1 and h[0:2] == '0x':
  h = h[2:]

 if len(h) % 2:
  h = "0" + h

 return h.decode('hex')

Source: http://opentechnotes.blogspot.com.au/2014/04/convert-values-to-from-integer-hex.html

You can do:

a = [9.0, 0.052999999999999999, 0.032575399999999997, 0.010892799999999999, 0.055702500000000002, 0.079330300000000006]
print ["%0.2f" % i for i in a]

# Linux

kubectl patch deployment <name> -p "{\"spec\":{\"template\":{\"metadata\":{\"annotations\":{\"date\":\"`date +'%s'`\"}}}}}"

# windows

kubectl patch deployment <name> -p (-join("{\""spec\"":{\""template\"":{\""metadata\"":{\""annotations\"":{\""date\"":\""" , $(Get-Date -Format o).replace(':','-').replace('+','_') , "\""}}}}}"))

The LDF file holds the database transaction log. See, for example, http://www.databasedesign-resource.com/sql-server-transaction-log.html for a full explanation. There are ways to shrink the transaction file; for example, see http://support.microsoft.com/kb/873235.

Adding to @Armand answer:

Add the following environment variable:

NODE_TLS_REJECT_UNAUTHORIZED=0 e.g. with export:

export NODE_TLS_REJECT_UNAUTHORIZED=0 (with great thanks to Juanra)

If you on windows usage:

set NODE_TLS_REJECT_UNAUTHORIZED=0

Thanks to: @weagle08

easy:

location.href.replace(/^http/, 'ws') + '/to/ws'
// or if you hate regexp:
location.href.replace('http://', 'ws://').replace('https://', 'wss://') + '/to/ws'

In read.table (and its relatives) it is the na.strings argument which specifies which strings are to be interpreted as missing values NA. The default value is na.strings = "NA"

If missing values in an otherwise numeric variable column are coded as something else than "NA", e.g. "." or "N/A", these rows will be interpreted as character, and then the whole column is converted to character.

Thus, if your missing values are some else than "NA", you need to specify them in na.strings.

You can do it the following way:

DoCmd.OpenQuery "yourQueryName", acViewNormal, acEdit

OR

CurrentDb.OpenRecordset("yourQueryName")

You can use jQuery to achieve this

Example:

$(function () {
        $('.map').maphilight();
    });

Go through this LINK to know more.

If the above one doesnt work then go through this link.

EDIT :

Give same class to each area tag like class="mapping"

and try this below code

$('.mapping').mouseover(function() {
    alert($(this).attr('id'));
}).mouseout(function(){
    alert('Mouseout....');      
});

os.path.abspath doesn't validate anything, so if we're already appending strings to __file__ there's no need to bother with dirname or joining or any of that. Just treat __file__ as a directory and start climbing:

# climb to __file__'s parent's parent:
os.path.abspath(__file__ + "/../../")

That's far less convoluted than os.path.abspath(os.path.join(os.path.dirname(__file__),"..")) and about as manageable as dirname(dirname(__file__)). Climbing more than two levels starts to get ridiculous.

But, since we know how many levels to climb, we could clean this up with a simple little function:

uppath = lambda _path, n: os.sep.join(_path.split(os.sep)[:-n])

# __file__ = "/aParent/templates/blog1/page.html"
>>> uppath(__file__, 1)
'/aParent/templates/blog1'
>>> uppath(__file__, 2)
'/aParent/templates'
>>> uppath(__file__, 3)
'/aParent'

The most efficient solution is the strtok function:

strtok($mystring, '/')

NOTE: In case of more than one character to split with the results may not meet your expectations e.g. strtok("somethingtosplit", "to") returns s because it is splitting by any single character from the second argument (in this case o is used).

@friek108 thanks for pointing that out in your comment.

For example:

$mystring = 'home/cat1/subcat2/';
$first = strtok($mystring, '/');
echo $first; // home

and

$mystring = 'home';
$first = strtok($mystring, '/');
echo $first; // home

I use rake db:reset which drops and then recreates the database and includes your seeds.rb file. http://guides.rubyonrails.org/migrations.html#resetting-the-database

If you're ok with POSIX, you can also use popen()/pclose()

#include <stdio.h>
#include <stdlib.h>

int main(void) {
/* ls -al | grep '^d' */
  FILE *pp;
  pp = popen("ls -al", "r");
  if (pp != NULL) {
    while (1) {
      char *line;
      char buf[1000];
      line = fgets(buf, sizeof buf, pp);
      if (line == NULL) break;
      if (line[0] == 'd') printf("%s", line); /* line includes '\n' */
    }
    pclose(pp);
  }
  return 0;
}

This is trivial when you use SUMPRODUCT. Por ejemplo:

=SUMPRODUCT((worksheet2!A:A=A3)*1)

You could put the above formula in cell B3, where A3 is the name you want to find in worksheet2.

For a jar file, the difference is in the classpath listed in the MANIFEST.MF file included in the jar if addClassPath is set to true in the maven-jar-plugin configuration. 'compile' dependencies will appear in the manifest, 'provided' dependencies won't.

One of my pet peeves is that these two words should have the same tense. Either compiled and provided, or compile and provide.

You can free memory used by vector by this way:

//Removes all elements in vector
v.clear()

//Frees the memory which is not used by the vector
v.shrink_to_fit();

Check out the node.js module list

• node-mysql — A node.js module implementing the MySQL protocol
• node-mysql2 — Yet another pure JS async driver. Pipelining, prepared statements.
• node-mysql-libmysqlclient — MySQL asynchronous bindings based on libmysqlclient

node-mysql looks simple enough:

var mysql      = require('mysql');
var connection = mysql.createConnection({
  host     : 'example.org',
  user     : 'bob',
  password : 'secret',
});

connection.connect(function(err) {
  // connected! (unless `err` is set)
});

Queries:

var post  = {id: 1, title: 'Hello MySQL'};
var query = connection.query('INSERT INTO posts SET ?', post, function(err, result) {
  // Neat!
});
console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'

It is not absolutely necessary since it can be done with IFs but it's more readable and also less expensive in run time.

I use it in order to skip an iteration in a loop if the data does not meet some requirements:

# List of times at which git commits were done.
# Formatted in hour, minutes in tuples.
# Note the last one has some fantasy.
commit_times = [(8,20), (9,30), (11, 45), (15, 50), (17, 45), (27, 132)]

for time in commit_times:
    hour = time[0]
    minutes = time[1]

    # If the hour is not between 0 and 24
    # and the minutes not between 0 and 59 then we know something is wrong.
    # Then we don't want to use this value,
    # we skip directly to the next iteration in the loop.
    if not (0 <= hour <= 24 and 0 <= minutes <= 59):
        continue

    # From here you know the time format in the tuples is reliable.
    # Apply some logic based on time.
    print("Someone commited at {h}:{m}".format(h=hour, m=minutes))

Output:

Someone commited at 8:20
Someone commited at 9:30
Someone commited at 11:45
Someone commited at 15:50
Someone commited at 17:45

As you can see, the wrong value did not make it after the continue statement.

$('.submit').filter(':checked').each(function() {
    //This is same as 'continue'
    if(something){
        return true;
    }
    //This is same as 'break'
    if(something){
        return false;
    }
});

For anyone looking to use this and keep the 'click' functionality (as John Landheer mentions in his comment), you can do it with just a couple of modifications:

Add a couple of globals:

var clickms = 100;
var lastTouchDown = -1;

Then modify the switch statement from the original to this:

var d = new Date();
switch(event.type)
{
    case "touchstart": type = "mousedown"; lastTouchDown = d.getTime(); break;
    case "touchmove": type="mousemove"; lastTouchDown = -1; break;        
    case "touchend": if(lastTouchDown > -1 && (d.getTime() - lastTouchDown) < clickms){lastTouchDown = -1; type="click"; break;} type="mouseup"; break;
    default: return;
}

You may want to adjust 'clickms' to your tastes. Basically it's just watching for a 'touchstart' followed quickly by a 'touchend' to simulate a click.

You may be misleaded about the username you use locally. That was my case in Windows 10 Home. When I look at users in control panel, I see the name usrpc01. However when I type net config workstation, it appears that the user's name is spc01. Seems like someone renamed the user, but the internal name remained unchanged.

Not knowing how to fix windows user name (and the folder name under C:\Users, which also refers to the original internal name), I added a new user accout on my db server.

The answer is simple. Just look at the image.

You can use this plugin, but for printing purpose i have added some code like <button onclick="window.print();">Print</button> and for saving image <button onclick="savePhoto();">Save Picture</button>

     function savePhoto() {
     var canvas = document.getElementById("canvas");
     var img    = canvas.toDataURL("image/png");
     window.location = img;}

checkout this plugin http://www.williammalone.com/articles/create-html5-canvas-javascript-drawing-app

You might also need to provide your user with an alert showing that those functions are disabled for the text input fields. This will work

    function showError(){_x000D_
     alert('you are not allowed to cut,copy or paste here');_x000D_
    }_x000D_
    _x000D_
    $('.form-control').bind("cut copy paste",function(e) {_x000D_
     e.preventDefault();_x000D_
    });

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<textarea class="form-control"  oncopy="showError()" onpaste="showError()"></textarea>

req.query will return a JS object after the query string is parsed.

/user?name=tom&age=55 - req.query would yield {name:"tom", age: "55"}

req.params will return parameters in the matched route. If your route is /user/:id and you make a request to /user/5 - req.params would yield {id: "5"}

req.param is a function that peels parameters out of the request. All of this can be found here.

UPDATE

If the verb is a POST and you are using bodyParser, then you should be able to get the form body in you function with req.body. That will be the parsed JS version of the POSTed form.

You might also try giving the full path to the binary you're trying to run. That solved my problem when trying to use ImageMagick.

tr td 
{
    border-bottom: 2px solid silver;
}

or if you want the border inside the TR tag, you can do this:

tr td {
    box-shadow: inset 0px -2px 0px silver;
}

This is generic code for configuration collection :

public class GenericConfigurationElementCollection<T> :   ConfigurationElementCollection, IEnumerable<T> where T : ConfigurationElement, new()
{
    List<T> _elements = new List<T>();

    protected override ConfigurationElement CreateNewElement()
    {
        T newElement = new T();
        _elements.Add(newElement);
        return newElement;
    }

    protected override object GetElementKey(ConfigurationElement element)
    {
        return _elements.Find(e => e.Equals(element));
    }

    public new IEnumerator<T> GetEnumerator()
    {
        return _elements.GetEnumerator();
    }
}

After you have GenericConfigurationElementCollection, you can simple use it in the config section (this is an example from my Dispatcher):

public class  DispatcherConfigurationSection: ConfigurationSection
{
    [ConfigurationProperty("maxRetry", IsRequired = false, DefaultValue = 5)]
    public int MaxRetry
    {
        get
        {
            return (int)this["maxRetry"];
        }
        set
        {
            this["maxRetry"] = value;
        }
    }

    [ConfigurationProperty("eventsDispatches", IsRequired = true)]
    [ConfigurationCollection(typeof(EventsDispatchConfigurationElement), AddItemName = "add", ClearItemsName = "clear", RemoveItemName = "remove")]
    public GenericConfigurationElementCollection<EventsDispatchConfigurationElement> EventsDispatches
    {
        get { return (GenericConfigurationElementCollection<EventsDispatchConfigurationElement>)this["eventsDispatches"]; }
    }
}

The Config Element is config Here:

public class EventsDispatchConfigurationElement : ConfigurationElement
{
    [ConfigurationProperty("name", IsRequired = true)]
    public string Name
    {
        get
        {
            return (string) this["name"];
        }
        set
        {
            this["name"] = value;
        }
    }
}

The config file would look like this:

<?xml version="1.0" encoding="utf-8" ?>
  <dispatcherConfigurationSection>
    <eventsDispatches>
      <add name="Log" ></add>
      <add name="Notification" ></add>
      <add name="tester" ></add>
    </eventsDispatches>
  </dispatcherConfigurationSection>

Hope it help !

You should not use your domain models in your views. ViewModels are the correct way to do it.

You need to map your domain model's necessary fields to viewmodel and then use this viewmodel in your controllers. This way you will have the necessery abstraction in your application.

If you never heard of viewmodels, take a look at this.

class A {
    private $aa;
    protected $bb = 'parent bb';

    function __construct($arg) {
       //do something..
    }

    private function parentmethod($arg2) {
       //do something..
    }
}

class B extends A {
    function __construct($arg) {
        parent::__construct($arg);
    }
    function childfunction() {
        echo parent::$this->bb; //works by M
    }
}

$test = new B($some);
$test->childfunction();`

At a guess I'd say the directory index is set to index.html, or some variant, try:

DirectoryIndex index.html index.php

This will still give index.html priority over index.php (handy if you need to throw up a maintenance page)

Trying to answer in simple way:

char * const a;  => a is (const) constant (*) pointer of type char {L <- R}. =>( Constant Pointer )
const char * a;  => a is (*) pointer to char constant             {L <- R}. =>( Pointer to Constant)

Constant Pointer:

pointer is constant !!. i.e, the address it is holding can't be changed. It will be stored in read only memory.

Let's try to change the address of pointer to understand more:

char * const a = &b; 
char c;
a = &c; // illegal , you can't change the address. `a` is const at L-value, so can't change. `a` is read-only variable.

It means once constant pointer points some thing it is forever.

pointer a points only b.

However you can change the value of b eg:

char b='a';
char * const a =&b;

printf("\n print a  : [%c]\n",*a);
*a = 'c';
printf("\n now print a  : [%c]\n",*a);

Pointer to Constant:

Value pointed by the pointer can't be changed.

const char *a;
char b = 'b';
const char * a =&b;
char c;
a=&c; //legal

*a = 'c'; // illegal , *a is pointer to constant can't change!.

If disk 'local' is not working for you then try this :

1. Change local to public in 'default' => env('FILESYSTEM_DRIVER', 'public'), from project_folder/config/filesystem.php
2. Clear config cache php artisan config:clear
3. Then create sym link php artisan storage:link

To get url of uploaded image you can use this Storage::url('iamge_name.jpg');

(something else) should be a.Country

if Country is nullable then make(something else) be a.Country OR a.Country is NULL

You can bulk import all aliases from one keystore to another:

keytool -importkeystore -srckeystore source.jks -destkeystore dest.jks

Use $_SERVER['REQUEST_METHOD'].

It seems that bames53's answer can be extended to defining integer and non-integer constant values in namespace and class declarations even if they get included in multiple source files. It is not necessary to put the declarations in a header file but the definitions in a source file. The following example works for Microsoft Visual Studio 2015, for z/OS V2.2 XL C/C++ on OS/390, and for g++ (GCC) 8.1.1 20180502 on GNU/Linux 4.16.14 (Fedora 28). Note that the constants are declared/defined in only a single header file that gets included in multiple source files.

In foo.cc:

#include <cstdio>               // for puts

#include "messages.hh"
#include "bar.hh"
#include "zoo.hh"

int main(int argc, const char* argv[])
{
  puts("Hello!");
  bar();
  zoo();
  puts(Message::third);
  return 0;
}

In messages.hh:

#ifndef MESSAGES_HH
#define MESSAGES_HH

namespace Message {
  char const * const first = "Yes, this is the first message!";
  char const * const second = "This is the second message.";
  char const * const third = "Message #3.";
};

#endif

In bar.cc:

#include "messages.hh"
#include <cstdio>

void bar(void)
{
  puts("Wow!");
  printf("bar: %s\n", Message::first);
}

In zoo.cc:

#include <cstdio>
#include "messages.hh"

void zoo(void)
{
  printf("zoo: %s\n", Message::second);
}

In bar.hh:

#ifndef BAR_HH
#define BAR_HH

#include "messages.hh"

void bar(void);

#endif

In zoo.hh:

#ifndef ZOO_HH
#define ZOO_HH

#include "messages.hh"

void zoo(void);

#endif

This yields the following output:

Hello!
Wow!
bar: Yes, this is the first message!
zoo: This is the second message.
Message #3.

The data type char const * const means a constant pointer to an array of constant characters. The first const is needed because (according to g++) "ISO C++ forbids converting a string constant to 'char*'". The second const is needed to avoid link errors due to multiple definitions of the (then insufficiently constant) constants. Your compiler might not complain if you omit one or both of the consts, but then the source code is less portable.

Assuming that ID is an identity column:

INSERT INTO TheTable(HospitalID, Email, Description)
SELECT 32, Email, Description FROM TheTable
WHERE HospitalID <> 32

Try to avoid loops with SQL. Try to think in terms of sets instead.

man,,, the answer is that you're basically testing PHP and not a database.

don't bother iterating the results, whether commenting out the print or not. there's a chunk of time.

   foreach ($cursor as $obj)
    {
        //echo $obj["thread_title"] . "<br><Br>";
    }

while the other chunk is spend yacking up a bunch of rand numbers.

function get_15_random_numbers()
{
    $numbers = array();
    for($i=1;$i<=15;$i++)
    {
        $numbers[] = mt_rand(1, 20000000) ;

    }
    return $numbers;
}

then theres a major difference b/w implode and in.

and finally what is going on here. looks like creating a connection each time, thus its testing the connection time plus the query time.

$m = new Mongo();

vs

$db = new AQLDatabase();

so your 101% faster might turn out to be 1000% faster for the underlying query stripped of jazz.

urghhh.

public static byte[] hexToBytes(String string) {
 int length = string.length();

Unfortunately I have not enouthg reputation to make a small contribution to the amazing @Alec McGail answer. I was using Python3 and I have needed to convert the map to a list following the @Alexis R comment.

Additionaly I have found the csv writer was adding a extra CR to the file (I have a empty line for each line with data inside the csv file). The solution was very easy following the @Jason R. Coombs answer to this thread: CSV in Python adding an extra carriage return

You need to simply add the lineterminator='\n' parameter to the csv.writer. It will be: csv_w = csv.writer( out_file, lineterminator='\n' )

I think you are looking for this ?

$('#your_id').html('<p>name</p><p><span style="font-size:xx-small;">ajde</span></p><p><em>da</em></p>').text();

if you want to remove only fast.. you can do like below..

$( "#tableId tbody tr" ).each( function(){
  this.parentNode.removeChild( this ); 
});

but, there can be some event-binded elements in table,

in that case,

above code is not prevent memory leak in IE... T-T and not fast in FF...

sorry....

My tests with git-2.0.0 today indicate that the --mirror option does not copy hooks, the config file, the description file, the info/exclude file, and at least in my test case a few refs (which I don't understand.)

I don't think checking the element's own visibility and display properties is good enough for requirement #1, even if you use currentStyle/getComputedStyle. You also have to check the element's ancestors. If an ancestor is hidden, so is the element.

What you are trying to do is an extension of string slicing in Python:

Say all strings are of length 10, last char to be removed:

>>> st[:9]
'abcdefghi'

To remove last N characters:

>>> N = 3
>>> st[:-N]
'abcdefg'

I faced the problem with my Jenkins. When I have renewed the certificate I started facing this error.

stderr fatal: unable to access server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt

So I have added my new certificate in the following file:

/etc/ssl/certs/ca-certificates.crt

The content of that file looks like this:

-----BEGIN CERTIFICATE-----
blahblha
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
blahblha
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
blahblha
-----END CERTIFICATE-----

Just append your certificate in the bottom:

-----BEGIN CERTIFICATE-----
blahblha
-----END CERTIFICATE-----

Your code was compiled with Java 8.

Either compile your code with an older JDK (compliance level) or run it on a Java 8 JRE.

Hope this helps...

Spring MVC runs on top of the Servlet API. So, you can use HttpServletRequest#getParameter() for this:

String value1 = request.getParameter("value1");
String value2 = request.getParameter("value2");

The HttpServletRequest should already be available to you inside Spring MVC as one of the method arguments of the handleRequest() method.

If you face the same error, here are the step by step instructions:

1. Open control panel
2. Then go to System
3. Then go to Change Environment Variables of the User
4. Then click create a new environment variables
5. Create a new variable named ANDROID_SDK_HOME
6. Set its value to your Android directory, like C:/users/<username>/.android

sql-surfer and MikroDel,

actually, the answer is not that complicated! You just need to add:

export JAVA_HOME=(/usr/libexec/java_home)

to your shell profile/configuration file. The only question is - which shell are you using? If you're using for example FISH, then adding that line to .profile or .bash_profile will not work at all. Adding it to config.fish file though will do the trick. Permanently.

old question but for newcomers that come around :

document.querySelector('div').outerHTML

For varchars, you may need to do something like this:

select convert(varchar(25), NULL) as abc_column into xyz_table

If you try

select '' as abc_column into xyz_table

you may get errors related to truncation, or an issue with null values, once you populate.

git branch copyOfMyBranch MyBranch

This avoids the potentially time-consuming and unnecessary act of checking out a branch. Recall that a checkout modifies the "working tree", which could take a long time if it is large or contains large files (images or videos, for example).

If you need to set the new value based on the old field value that is do something like:

update my_table set field_1 = field_1 + 1 where pk_field = some_value

use query expressions:

MyModel.objects.filter(pk=some_value).update(field1=F('field1') + 1)

This will execute update atomically that is using one update request to the database without reading it first.

retry-safe.

Is usually the easiest way to understand its meaning in computer science.

A good question always have multiple answers, to reduce and help you choose the right answer, here I am adding my own too. I have tested it and it works fine.

AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:@"http://www.yourdomain.com/appname/data/ws/index.php/user/login/"]];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

[manager POST:@"POST" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSString *json = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"%@", json);
    //Now convert json string to dictionary.
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"%@", error.localizedDescription);
}];

There is a subtle issue here that is a bit of a gotcha.

The toString() method has a base implementation in Object. CharSequence is an interface; and although the toString() method appears as part of that interface, there is nothing at compile-time that will force you to override it and honor the additional constraints that the CharSequence toString() method's javadoc puts on the toString() method; ie that it should return a string containing the characters in the order returned by charAt().

Your IDE won't even help you out by reminding that you that you probably should override toString(). For example, in intellij, this is what you'll see if you create a new CharSequence implementation: http://puu.sh/2w1RJ. Note the absence of toString().

If you rely on toString() on an arbitrary CharSequence, it should work provided the CharSequence implementer did their job properly. But if you want to avoid any uncertainty altogether, you should use a StringBuilder and append(), like so:

final StringBuilder sb = new StringBuilder(charSequence.length());
sb.append(charSequence);
return sb.toString();

class Test extends Thread
{
    public void run(){  
        try{  
            Thread.sleep(10000);  
        }catch(InterruptedException e){  
            System.out.println("test1");
            throw new RuntimeException("Thread interrupted..."+e);  
        }  

    }  

    public static void main(String args[]){  
        Test t1=new Test1();  
        t1.start();  
        try{  
            t1.interrupt();  
        }catch(Exception e){

            System.out.println("Exception handled "+e);
        }  

    }  
}

Its output doesn't contain test2 , so its not handling runtime exception. @jon skeet, @Jan Zyka

I had the same issue and even after importing/adding a jar/library as mentioned in the answers it would not solve the error. Out of frustration, I just created a new workspace and created a fresh android project and it automatically imported appcompat_v7 and there were no errors on clean and build. Didn't have to import a single jar/ library manually. Just FYI I am using eclipse Mars.1 Release (4.5.1) and was facing the exact same issue everytime I created a new android project.

If you only need to display the images base on a tag, then there is not to include the wrapper class "instagram.class.php". As the Media & Tag Endpoints in Instagram API do not require authentication. You can use the following curl based function to retrieve results based on your tag.

 function callInstagram($url)
    {
    $ch = curl_init();
    curl_setopt_array($ch, array(
    CURLOPT_URL => $url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_SSL_VERIFYPEER => false,
    CURLOPT_SSL_VERIFYHOST => 2
    ));

    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
    }

    $tag = 'YOUR_TAG_HERE';
    $client_id = "YOUR_CLIENT_ID";
    $url = 'https://api.instagram.com/v1/tags/'.$tag.'/media/recent?client_id='.$client_id;

    $inst_stream = callInstagram($url);
    $results = json_decode($inst_stream, true);

    //Now parse through the $results array to display your results... 
    foreach($results['data'] as $item){
        $image_link = $item['images']['low_resolution']['url'];
        echo '<img src="'.$image_link.'" />';
    }

I had c++ codes in my project but i didn't have NDK installed, installing it solved the problem

Another possible cause is that the clock of your machine is not synced (e.g. on Raspberry Pi). Check the current date/time using:

$ date

If the date and/or time is incorrect, try to update using:

$ sudo ntpdate -u time.nist.gov

Super-simple HTML 5 Solution:

<input type="search" placeholder="Search..." />

Source: HTML 5 Tutorial - Input Type: Search

That works in at least Chrome 8, Edge 14, IE 10, and Safari 5 and does not require Bootstrap or any other library. (Unfortunately, it seems Firefox does not support the search clear button yet.)

After typing in the search box, an 'x' will appear which can be clicked to clear the text. This will still work as an ordinary edit box (without the 'x' button) in other browsers, such as Firefox, so Firefox users could instead select the text and press delete, or...

If you really need this nice-to-have feature supported in Firefox, then you could implement one of the other solutions posted here as a polyfill for input[type=search] elements. A polyfill is code that automatically adds a standard browser feature when the user's browser doesn't support the feature. Over time, the hope is that you'd be able to remove polyfills as browsers implement the respective features. And in any case, a polyfill implementation can help to keep the HTML code cleaner.

By the way, other HTML 5 input types (such as "date", "number", "email", etc.) will also degrade gracefully to a plain edit box. Some browsers might give you a fancy date picker, a spinner control with up/down buttons, or (on mobile phones) a special keyboard that includes the '@' sign and a '.com' button, but to my knowledge, all browsers will at least show a plain text box for any unrecognized input type.

Bootstrap 3 & HTML 5 Solution

Bootstrap 3 resets a lot of CSS and breaks the HTML 5 search cancel button. After the Bootstrap 3 CSS has been loaded, you can restore the search cancel button with the CSS used in the following example:

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<style>_x000D_
  input[type="search"]::-webkit-search-cancel-button {_x000D_
    -webkit-appearance: searchfield-cancel-button;_x000D_
  }_x000D_
</style>_x000D_
<div class="form-inline">_x000D_
  <input type="search" placeholder="Search..." class="form-control" />_x000D_
</div>

Source: HTML 5 Search Input Does Not Work with Bootstrap

I have tested that this solution works in the latest versions of Chrome, Edge, and Internet Explorer. I am not able to test in Safari. Unfortunately, the 'x' button to clear the search does not appear in Firefox, but as above, a polyfill could be implemented for browsers that don't support this feature natively (i.e. Firefox).

Do not forget the . at the end, which indicates end of line

Some times there are problems with funtion/features that do not interact with the DOM

try to change the value sharply and then assign the $scope

document.getElementById ("textWidget") value = "<NewVal>";
$scope.widget.title = "<NewVal>";

I had the similar issue - could not figure out what was the reason, but I fixed it using following code. Somehow it could not focus only the blank inputs:

$('input').click(function () {
        var val = $(this).val();
        if (val == "") {
            this.select();
        }
    });

You can make use of the removeIf to remove data from a list conditionally.

Eg:- If you want to remove all even numbers from a list, you can do it as follows.

    final List<Integer> list = IntStream.range(1,100).boxed().collect(Collectors.toList());

    list.removeIf(number -> number % 2 == 0);

Another option is Array.isArray()

if(! Array.isArray(classNames) ){
    classNames = [classNames]
}

This is the shortest way.

var now = new Date().toLocaleTimeString();
console.log(now)

Here is also a way through string manipulation that was not mentioned.

var now = new Date()
console.log(now.toString().substr(16,8))

try yo write document.getElementById('id').style.visibility="hidden";

You can filter by an object with a property matching the objects you have to filter on it:

app.controller('FooCtrl', function($scope) {
   $scope.products = [
       { id: 1, name: 'test', color: 'red' },
       { id: 2, name: 'bob', color: 'blue' }
       /*... etc... */
   ];
});

<div ng-repeat="product in products | filter: { color: 'red' }"> 

This can of course be passed in by variable, as Mark Rajcok suggested.

As for the environment variables:

import os
print os.environ["HOME"]

I'm afraid you'd have to flesh out your second point a little bit more before a decent answer is possible.

You can install pidof with Homebrew:

brew install pidof
pidof <process_name>

I tried using a CLR function and it was more than twice as fast as BCP. Here's my code.

Original Method:

SET @bcpCommand = 'bcp "SELECT blobcolumn FROM blobtable WHERE ID = ' + CAST(@FileID AS VARCHAR(20)) + '" queryout "' + @FileName + '" -T -c'
EXEC master..xp_cmdshell @bcpCommand

CLR Method:

declare @file varbinary(max) = (select blobcolumn from blobtable WHERE ID = @fileid)
declare @filepath nvarchar(4000) = N'c:\temp\' + @FileName
SELECT Master.dbo.WriteToFile(@file, @filepath, 0)

C# Code for the CLR function

using System;
using System.Data;
using System.Data.SqlTypes;
using System.IO;
using Microsoft.SqlServer.Server;

namespace BlobExport
{
    public class Functions
    {
      [SqlFunction]
      public static SqlString WriteToFile(SqlBytes binary, SqlString path, SqlBoolean append)
      {        
        try
        {
          if (!binary.IsNull && !path.IsNull && !append.IsNull)
          {         
            var dir = Path.GetDirectoryName(path.Value);           
            if (!Directory.Exists(dir))              
              Directory.CreateDirectory(dir);            
              using (var fs = new FileStream(path.Value, append ? FileMode.Append : FileMode.OpenOrCreate))
            {
                byte[] byteArr = binary.Value;
                for (int i = 0; i < byteArr.Length; i++)
                {
                    fs.WriteByte(byteArr[i]);
                };
            }
            return "SUCCESS";
          }
          else
             "NULL INPUT";
        }
        catch (Exception ex)
        {          
          return ex.Message;
        }
      }
    }
}

If you have npm and node installed : npm install -g ip && node -e "const ip = require('ip'); console.log(ip.address())"

Sometimes it takes longer to figure out the regex than to just write it out in python:

import string
s = "how much for the maple syrup? $20.99? That's ricidulous!!!"
for char in string.punctuation:
    s = s.replace(char, ' ')

If you need other characters you can change it to use a white-list or extend your black-list.

Sample white-list:

whitelist = string.letters + string.digits + ' '
new_s = ''
for char in s:
    if char in whitelist:
        new_s += char
    else:
        new_s += ' '

Sample white-list using a generator-expression:

whitelist = string.letters + string.digits + ' '
new_s = ''.join(c for c in s if c in whitelist)

Some old fortran code I saw:

     integer *4 one,two,three;

c    asssign one to 100 before entering the loop
     one=100;

@recursive's solusion (The accepted answer) is 100% right. I am just adding a sample code for your reference.

My case is to display price with two decimal digits.This is part of back-end response: "price": 2300, "currencySymbol": "CD", ....

This is my helper class:

public class CurrencyUtils
{
    private static final String[] suffix = { "", "K", "M" };

    public static String getCompactStringForDisplay(final int amount)
    {
        int suffixIndex;
        if (amount >= 1_000_000) {
            suffixIndex = 2;
        } else if (amount >= 1_000) {
            suffixIndex = 1;
        } else {
            suffixIndex = 0;
        }

        int quotient;
        int remainder;
        if (amount >= 1_000_000) {
            quotient = amount / 1_000_000;
            remainder = amount % 1_000_000;
        } else if (amount >= 1_000) {
            quotient = amount / 1_000;
            remainder = amount % 1_000;
        } else {
            return String.valueOf(amount);
        }

        if (remainder == 0) {
            return String.valueOf(quotient) + suffix[suffixIndex];
        }

        // Keep two most significant digits
        if (remainder >= 10_000) {
            remainder /= 10_000;
        } else if (remainder >= 1_000) {
            remainder /= 1_000;
        } else if (remainder >= 100) {
            remainder /= 10;
        }

        return String.valueOf(quotient) + '.' + String.valueOf(remainder) + suffix[suffixIndex];
    }
}

This is my test class (based on Junit 4):

public class CurrencyUtilsTest {

    @Test
    public void getCompactStringForDisplay() throws Exception {
        int[] numbers = {0, 5, 999, 1_000, 5_821, 10_500, 101_800, 2_000_000, 7_800_000, 92_150_000, 123_200_000, 9_999_999};
        String[] expected = {"0", "5", "999", "1K", "5.82K", "10.50K", "101.80K", "2M", "7.80M", "92.15M", "123.20M", "9.99M"};

        for (int i = 0; i < numbers.length; i++) {
            int n = numbers[i];
            String formatted = CurrencyUtils.getCompactStringForDisplay(n);
            System.out.println(n + " => " + formatted);

            assertEquals(expected[i], formatted);
        }
    }

}

just create a new sheet with cells with linebreak, save it to csv then open it with an editor that can show the end of line characters (like notepad++). By doing that you will notice that a linebreak in a cell is coded with LF while a "real" end of line is code with CR LF. Voilà, now you know how to generate a "correct" csv file for excel.

Building on icova's answer, here's the code so you can use a custom HTML5 validation message:

$(function() {
    var requiredCheckboxes = $(':checkbox[required]');
    requiredCheckboxes.change(function() {
        if (requiredCheckboxes.is(':checked')) {requiredCheckboxes.removeAttr('required');}
        else {requiredCheckboxes.attr('required', 'required');}
    });
    $("input").each(function() {
        $(this).on('invalid', function(e) {
            e.target.setCustomValidity('');
            if (!e.target.validity.valid) {
                e.target.setCustomValidity('Please, select at least one of these options');
            }
        }).on('input, click', function(e) {e.target.setCustomValidity('');});
    });
});

I ended up using this handy macro:

#define STRING(value)               [@(value) stringValue]

I assume you mean you're looking for something that is faster than datetime.datetime.strftime(), and are essentially stripping the non-alpha characters from a utc timestamp.

You're approach is marginally faster, and I think you can speed things up even more by slicing the string:

>>> import timeit
>>> t=timeit.Timer('datetime.utcnow().strftime("%Y%m%d%H%M%S%f")','''
... from datetime import datetime''')
>>> t.timeit(number=10000000)
116.15451288223267

>>> def replaceutc(s):
...     return s\
...         .replace('-','') \
...         .replace(':','') \
...         .replace('.','') \
...         .replace(' ','') \
...         .strip()
... 
>>> t=timeit.Timer('replaceutc(str(datetime.datetime.utcnow()))','''
... from __main__ import replaceutc
... import datetime''')
>>> t.timeit(number=10000000)
77.96774983406067

>>> def sliceutc(s):
...     return s[:4] + s[5:7] + s[8:10] + s[11:13] + s[14:16] + s[17:19] + s[20:]
... 
>>> t=timeit.Timer('sliceutc(str(datetime.utcnow()))','''
... from __main__ import sliceutc
... from datetime import datetime''')
>>> t.timeit(number=10000000)

In Oracle the location that contains information about all database objects including tables and stored procedures is called the Data Dictionary. It is a collection of views that provides you with access to the metadata that defines the database. You can query the Data Dictionary views for a list of desired database objects and then use the functions available in dbms_metadata package to get the DDL for each object. Alternative is to investigate the support in dbms_metadata to export DDLs for a collection of objects.

For a few pointers, for example to get a list of tables you can use the following Data Dictionary views

• user_tables contains all tables owned by the user
• all_tables contains all tables that are accessible by the user
• and so on...

When you declare:

new Vue({
    el: '#app',
    data () {
      return {}
    }
)}

That is typically your root Vue instance that the rest of the application descends from. This hangs off the root element declared in an html document, for example:

<html>
  ...
  <body>
    <div id="app"></div>
  </body>
</html>

The other syntax is declaring a component which can be registered and reused later. For example, if you create a single file component like:

// my-component.js
export default {
    name: 'my-component',
    data () {
      return {}
    }
}

You can later import this and use it like:

// another-component.js
<template>
  <my-component></my-component>
</template>
<script>
  import myComponent from 'my-component'
  export default {
    components: {
      myComponent
    }
    data () {
      return {}
    }
    ...
  }
</script>

Also, be sure to declare your data properties as functions, otherwise they are not going to be reactive.

<input type="text" id="firstname" placeholder="First Name"

Note: You can change the placeholder, id and type value to "email" or whatever suits your need.

Assuming the quotation marks are actually part of the output, couldn't you just use the -o switch to return everything between the quote marks?

COMPANY_NAME="\"ABC Inc\";" | echo $COMPANY_NAME | grep -o "\"*.*\""

for javascript

const test = new RegExp('^[+]?([0-9]{0,})*[.]?([0-9]{0,2})?$','g');

Which would work for 1.23 1234.22 0 0.12 12

You can change the parts in the {} to get different results in decimal length and front of the decimal as well. This is used in inputs for entering in number and checking every input as you type only allowing what passes.

Is this what you are looking for?

d = dict()
d[15.0]='fifteen'
d[14.0]='fourteen'
d[14.5]='fourteenandhalf'

print d[min(d.keys())]

Prints 'fourteen'

I was having the same problem, the mysql service was starting but not the apache service, the main problem about that is one of your virtual hosts isn't config. correctly, all i did was deleted the virtual host that i created "D:\wamp\bin\apache\apache2.4.23\conf\extra\httpd-vhosts, restarted all services apache service started working correctly and so i just went to localhost and added a virtual host automatically and so it worked!!

var inValid = new RegExp('^[_A-z0-9]{1,}$');
var value = "test string";
var k = inValid.test(value);
alert(k);

String[] result = "hi i'm paul".split("\\s+"); to split across one or more cases.

Or you could take a look at Apache Common StringUtils. It has StringUtils.split(String str) method that splits string using white space as delimiter. It also has other useful utility methods

Setting that is not that hard as mentioned in the question. Actually it's pretty simple. Try this on storyboard.

TortoiseSVN doesn't use svn.exe it has SVN library compiled in. If you need to run your own tasks you would have to install stand alone subversion client. You either from Cygwin [http://cygwin.com ] or get a native version from http://subversion.apache.org/packages.html#windows

Seeing a user banging away at a control that overrides her decisions is a sad sight. Set the control's Enabled property to False. If you don't like that then change its Items property so only one item is selectable.

Setting the underlying socket ReceiveTimeout property did the trick. You can access it like this: yourTcpClient.Client.ReceiveTimeout. You can read the docs for more information.

Now the code will only "sleep" as long as needed for some data to arrive in the socket, or it will raise an exception if no data arrives, at the beginning of a read operation, for more than 20ms. I can tweak this timeout if needed. Now I'm not paying the 20ms price in every iteration, I'm only paying it at the last read operation. Since I have the content-length of the message in the first bytes read from the server I can use it to tweak it even more and not try to read if all expected data has been already received.

I find using ReceiveTimeout much easier than implementing asynchronous read... Here is the working code:

string SendCmd(string cmd, string ip, int port)
{
  var client = new TcpClient(ip, port);
  var data = Encoding.GetEncoding(1252).GetBytes(cmd);
  var stm = client.GetStream();
  stm.Write(data, 0, data.Length);
  byte[] resp = new byte[2048];
  var memStream = new MemoryStream();
  var bytes = 0;
  client.Client.ReceiveTimeout = 20;
  do
  {
      try
      {
          bytes = stm.Read(resp, 0, resp.Length);
          memStream.Write(resp, 0, bytes);
      }
      catch (IOException ex)
      {
          // if the ReceiveTimeout is reached an IOException will be raised...
          // with an InnerException of type SocketException and ErrorCode 10060
          var socketExept = ex.InnerException as SocketException;
          if (socketExept == null || socketExept.ErrorCode != 10060)
              // if it's not the "expected" exception, let's not hide the error
              throw ex;
          // if it is the receive timeout, then reading ended
          bytes = 0;
      }
  } while (bytes > 0);
  return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}
