Your model is @Messages, change it to @message.

To change it like you should use migration:

def change   rename_table :old_table_name, :new_table_name end 

Of course do not create that file by hand but use rails generator:

rails g migration ChangeMessagesToMessage 

That will generate new file with proper timestamp in name in 'db dir. Then run:

rake db:migrate 

And your app should be fine since then.

The major difference between these tools is how they copy files.

scp basically reads the source file and writes it to the destination. It performs a plain linear copy, locally, or over a network.

rsync also copies files locally or over a network. But it employs a special delta transfer algorithm and a few optimizations to make the operation a lot faster. Consider the call.

rsync A host:B

• rsync will check files sizes and modification timestamps of both A and B, and skip any further processing if they match.

• If the destination file B already exists, the delta transfer algorithm will make sure only differences between A and B are sent over the wire.

• rsync will write data to a temporary file T, and then replace the destination file B with T to make the update look "atomic" to processes that might be using B.

Another difference between them concerns invocation. rsync has a plethora of command line options, allowing the user to fine tune its behavior. It supports complex filter rules, runs in batch mode, daemon mode, etc. scp has only a few switches.

In summary, use scp for your day to day tasks. Commands that you type once in a while on your interactive shell. It's simpler to use, and in those cases rsync optimizations won't help much.

For recurring tasks, like cron jobs, use rsync. As mentioned, on multiple invocations it will take advantage of data already transferred, performing very quickly and saving on resources. It is an excellent tool to keep two directories synchronized over a network.

Also, when dealing with large files, use rsync with the -P option. If the transfer is interrupted, you can resume it where it stopped by reissuing the command. See Sid Kshatriya's answer.

In order to run ssh-add on Windows one could install git using choco install git. The ssh-add command is recognized once C:\Program Files\Git\usr\bin has been added as a PATH variable and the command prompt has been restarted:

C:\Users\user\Desktop\repository>ssh-add .ssh/id_rsa
Enter passphrase for .ssh/id_rsa:
Identity added: .ssh/id_rsa (.ssh/id_rsa)

C:\Users\user\Desktop\repository> 

Seems there is a change in handling of attribute protection and now you must whitelist params in the controller (instead of attr_accessible in the model) because the former optional gem strong_parameters became part of the Rails Core.

This should look something like this:

class PeopleController < ActionController::Base
  def create
    Person.create(person_params)
  end

private
  def person_params
    params.require(:person).permit(:name, :age)
  end
end

So params.require(:model).permit(:fields) would be used

and for nested attributes something like

params.require(:person).permit(:name, :age, pets_attributes: [:id, :name, :category])

Some more details can be found in the Ruby edge API docs and strong_parameters on github or here

With a non-US keyboard layout the default shortcut Ctrl+/ (Win/Linux) does not work.

I managed to change it into Ctrl+1 as per Robert's comment by writing

[
{
    "keys": ["ctrl+1"],
    "command": "toggle_comment",
    "args": { "block": false } 
}
,
{   "keys": ["ctrl+shift+1"],
    "command": "toggle_comment",
    "args": { "block": true }
}
]

to Preferences -> Key Bindings (on the right half, the user keymap).

Note that there should be only one set of brackets ('[]') at the right side; if you had there something already, copy paste this between the brackets and keep only the outermost brackets.

You clone a repository with git clone [url]. Like so,

$ git clone https://github.com/libgit2/libgit2

Another cool shorthand, unknown to many, is

array.each(&method(:foo))

which is a shorthand for

array.each { |element| foo(element) }

By calling method(:foo) we took a Method object from self that represents its foo method, and used the & to signify that it has a to_proc method that converts it into a Proc.

This is very useful when you want to do things point-free style. An example is to check if there is any string in an array that is equal to the string "foo". There is the conventional way:

["bar", "baz", "foo"].any? { |str| str == "foo" }

And there is the point-free way:

["bar", "baz", "foo"].any?(&"foo".method(:==))

The preferred way should be the most readable one.

I listen to The Guardian's TechWeekly, it's very informed for being done by journalists for a mainstream newspaper. Well produced and up to date. Has a focus on Britain and Europe.

Just stick with the virtual machine: If you're running Internet Explorer 8 you'll be able to activate the developer window using F12. There you're able to edit CSS as well as HTML on the fly without saving/reloading the page.

You have to go with a DVCS, it is like a quantum leap in source management. Personally I use Monotone and its sped up development time no end. We are using it for Windows, Linux and Mac and it has been very stable. I even have buildbot doing nightly builds of the project on each of the platforms.

DVCS while being distributed usually means you will create a central server just for people to push changes to and from.

Make sure you have your maven bin directory in the path and the JAVA_HOME property set

This worked for me.

   var regex = /(&nbsp;|<([^>]+)>)/ig
      ,   body = tt
     ,   result = body.replace(regex, "");
       alert(result);

What you have is piping the text "cat test" into the loop.

You just want:

cat test | \
while read CMD; do
    echo $CMD
done

or can do this...
set all btn ( class name like : .btn- + $theme-colors: map-merge ) styles at one time :

@each $color, $value in $theme-colors {
  .btn-#{$color} {
    @include button-variant($value, $value,
    // modify
    $hover-background: lighten($value, 7.5%),
    $hover-border: lighten($value, 10%),
    $active-background: lighten($value, 10%),
    $active-border: lighten($value, 12.5%)
    // /modify
    );
  }
}

// code from "node_modules/bootstrap/scss/_buttons.scss"

should add into your customization scss file.

Matlab code of two methods that have been published in highly regarded journals (IEEE Transactions on Image Processing) are available here: https://ivulab.asu.edu/software

check the CPBDM and JNBM algorithms. If you check the code it's not very hard to be ported and incidentally it is based on the Marzialiano's method as basic feature.

A short version would be:

echo sh(script: 'ls -al', returnStdout: true).result

You can get this done using html string and setting the html to Textview using
txtView.setText(Html.fromHtml("Your html string here"));

For example :

txtView.setText(Html.fromHtml("<html><body><font size=5 color=red>Hello </font> World </body><html>"));`

The way that Java Swing UIs work is that for each JPanel there is always a LayoutManager that decides on where to exactly place your components. Each layout managers works differently, so if you use for example a BorderLayout, setBounds() is not used by the LayoutManager, instead component placement is decided by East,West,South,North,Center.

For the NullLayoutManager (in case you used new JPanel(null)) however, each component has to have an x and y coordinate. Stupid Sidenote: if your UI would be three-dimensional there would also be a z coordinate.

So with public void Component.setBounds(int x, int y, int width, int height) you specify where your component is placed and how many pixel it is wide and high.

Here's an example:

import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class JTableInNullLayout
{
  public static void main(String[] argv) throws Exception {

      JPanel panel = new JPanel(null);

      JLabel helloLabel = new JLabel("Hello world!");
      helloLabel.setBounds( 10, 50, 60, 20 ); // x, y, width, height
      panel.add(helloLabel);

      JFrame frame = new JFrame();
      frame.add(panel);
      frame.setPreferredSize( new Dimension(200,200));
      frame.pack();
      frame.setVisible(true);
  }
}

Open github app. Then, add the Folder of files into the github repo file onto your computer (You WILL need to copy the repo onto your computer. Most repo files are located in the following directory: C:\Users\USERNAME\Documents\GitHub\REPONAME) Then, in the github app, check our your repo. You can easily commit from there.

To answer the updated part of your question: to style the drawer icon/arrow, you have two options:

Style the arrow itself

To do this, override drawerArrowStyle in your theme like so:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="drawerArrowStyle">@style/MyTheme.DrawerArrowToggle</item>
</style>
<style name="MyTheme.DrawerArrowToggle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="color">@android:color/holo_purple</item>
    <!-- ^ this will make the icon purple -->
</style>

This is probably not what you want, because the ActionBar itself should have consistent styling with the arrow, so, most probably, you want the option two:

Theme the ActionBar/Toolbar

Override the android:actionBarTheme (actionBarTheme for appcompat) attribute of the global application theme with your own theme (which you probably should derive from ThemeOverlay.Material.ActionBar/ThemeOverlay.AppCompat.ActionBar) like so:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="actionBarTheme">@style/MyTheme.ActionBar</item>
</style>
<style name="MyTheme.ActionBar" parent="ThemeOverlay.AppCompat.ActionBar">
    <item name="android:textColorPrimary">@android:color/white</item>
    <!-- ^ this will make text and arrow white -->
    <!-- you can also override drawerArrowStyle here -->
</style>

An important note here is that when using a custom layout with a Toolbar instead of stock ActionBar implementation (e.g. if you're using the DrawerLayout-NavigationView-Toolbar combo to achieve the Material-style drawer effect where it's visible under translucent statusbar), the actionBarTheme attribute is obviosly not picked up automatically (because it's meant to be taken care of by the AppCompatActivity for the default ActionBar), so for your custom Toolbar don't forget to apply your theme manually:

<!--inside your custom layout with DrawerLayout
and NavigationView or whatever -->
<android.support.v7.widget.Toolbar
        ...
        app:theme="?actionBarTheme">

-- this will resolve to either AppCompat's default ThemeOverlay.AppCompat.ActionBar or your override if you set the attribute in your derived theme.

PS a little comment about the drawerArrowStyle override and the spinBars attribute -- which a lot of sources suggest should be set to true to get the drawer/arrow animation. Thing is, spinBars it is true by default in AppCompat (check out the Base.Widget.AppCompat.DrawerArrowToggle.Common style), you don't have to override actionBarTheme at all to get the animation working. You get the animation even if you do override it and set the attribute to false, it's just a different, less twirly animation. The important thing here is to use ActionBarDrawerToggle, it's what pulls in the fancy animated drawable.

all of the solution here are great but not necessarily can be implemented for old mysql servers (at least at my case). so you can use sub-queries (i think it is less complicated).

 select sum(t1.cnt) from 
        (SELECT column, COUNT(column) as cnt
            FROM
            table 
            GROUP BY 
            column
            HAVING 
            COUNT(column) > 1) as t1 ;

In your form tag just paste this:

onkeypress="return event.keyCode != 13;"

Example

<input type="text" class="search" placeholder="search" onkeypress="return event.keyCode != 13;">

This can be useful if you want to do search when typing and ignoring ENTER.

/// Grab the search term
const searchInput = document.querySelector('.search')
/// Update search term when typing
searchInput.addEventListener('keyup', displayMatches)

One should also consider another intuitive way to do this using filter() from dplyr. Here are some examples:

set.seed(123)
df <- data.frame(name = sample(letters, 100, TRUE),
                 date = sample(1:500, 100, TRUE))
library(dplyr)
filter(df, date < 50) # date less than 50
filter(df, date %in% 50:100) # date between 50 and 100
filter(df, date %in% 1:50 & name == "r") # date between 1 and 50 AND name is "r"
filter(df, date %in% 1:50 | name == "r") # date between 1 and 50 OR name is "r"

# You can also use the pipe (%>%) operator
df %>% filter(date %in% 1:50 | name == "r")

A sample - write multiple rows with boolean column (using example above by GaretJax and Eran?).

import csv
RESULT = [['IsBerry','FruitName'],
          [False,'apple'],
          [True, 'cherry'],
          [False,'orange'],
          [False,'pineapple'],
          [True, 'strawberry']]
with open("../datasets/dashdb.csv", 'wb') as resultFile:
    wr = csv.writer(resultFile, dialect='excel')
    wr.writerows(RESULT)

Result:

df_data_4 = pd.read_csv('../datasets/dashdb.csv')
df_data_4.head()

Output:

   IsBerry  FruitName
   0    False   apple
   1    True    cherry
   2    False   orange
   3    False   pineapple
   4    True    strawberry

I suggest you to make this generic code :

$('a[href^="#"]').click(function(){

var the_id = $(this).attr("href");

    $('html, body').animate({
        scrollTop:$(the_id).offset().top
    }, 'slow');

return false;});

"But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?"_x000D_

Consider an IBM 1403 impact printer. CR moved the print head to the start of the line, but did NOT advance the paper. This allowed for "overprinting", placing multiple lines of output on one line. Things like underlining were achieved this way, as was BOLD print. LF advanced the paper one line. If there was no CR, the next line would print as a staggered-step because LF didn't move the print head. FF advanced the paper to the next page. It typically also moved the print head to the start of the first line on the new page, but you might need CR for that. To be sure, most programmers coded CRFF instead of CRLF at the end of the last line on a page because an extra CR created by FF wouldn't matter.

I don't think you can set arbitrarily sized images on any of the existing button classes. If you want a simple image behaving like a button, you can write your own QAbstractButton-subclass, something like:

class ImageButton : public QAbstractButton {
Q_OBJECT
public:
...
    void setPixmap( const QPixmap& pm ) { m_pixmap = pm; update(); }
    QSize sizeHint() const { return m_pixmap.size(); }
protected:
    void paintEvent( QPaintEvent* e ) {
        QPainter p( this );
        p.drawPixmap( 0, 0, m_pixmap );
    }
};

if you have multiple sets of numbers then this is another option

>>> import re
>>> print(re.findall('\d+', 'xyz123abc456def789'))
['123', '456', '789']

its no good for floating point number strings though.

You can achieve this with the background-size property, which is now supported by most browsers.

To scale the background image to fit inside the div:

background-size: contain;

To scale the background image to cover the whole div:

background-size: cover;

There also exists a filter for IE 5.5+ support, as well as vendor prefixes for some older browsers.

You should implement a Custom List View, such that you define a Layout once and draw it for every row in the list view.

one of the simplest ways to create a string matrix is as follow :

x = [ {'first string'} {'Second parameter} {'Third text'} {'Fourth component'} ]

For Excel 2010 it should be UTF-8. Instruction by MS :
http://msdn.microsoft.com/en-us/library/bb507946:

"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
    <sheets>
        <sheet name="MySheet1" sheetId="1" r:id="rId1" /> 
        <sheet name="MySheet2" sheetId="2" r:id="rId2" /> 
    </sheets>
</workbook>

The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" ?> 
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
    <sheetData>
        <row r="1">
            <c r="A1">
                <v>100</v> 
            </c>
        </row>
    </sheetData>
</worksheet>

AFAIK the json module was added in version 2.6, see here. I'm guessing you can update your python installation to the latest stable 2.6 from this page.

EDIT: After your comments, I understand that you want to pass variable through your form.

You can do this using hidden field:

<input type='hidden' name='var' value='<?php echo "$var";?>'/> 

In PHP action File:

<?php 
   if(isset($_POST['var'])) $var=$_POST['var'];
?>

Or using sessions: In your first page:

 $_SESSION['var']=$var;

start_session(); should be placed at the beginning of your php page.

In PHP action File:

if(isset($_SESSION['var'])) $var=$_SESSION['var'];

First Answer:

You can also use $GLOBALS :

if (isset($_POST['save_exit']))
{

   echo $GLOBALS['var']; 

}

You might try searching the internet for ".htaccess Options not allowed here".

A suggestion I found (using google) is:

Check to make sure that your httpd.conf file has AllowOverride All.

A .htaccess file that works for me on Mint Linux (placed in the Laravel /public folder):

# Apache configuration file
# http://httpd.apache.org/docs/2.2/mod/quickreference.html

# Turning on the rewrite engine is necessary for the following rules and

Extending Tomáš Zato idea. Tomas's Array.prototype.compare should be infact called Array.prototype.compareIdentical.

It passes on:

[1, 2, [3, 4]].compareIdentical ([1, 2, [3, 2]]) === false;
[1, "2,3"].compareIdentical ([1, 2, 3]) === false;
[1, 2, [3, 4]].compareIdentical ([1, 2, [3, 4]]) === true;
[1, 2, 1, 2].compareIdentical ([1, 2, 1, 2]) === true;

But fails on:

[[1, 2, [3, 2]],1, 2, [3, 2]].compareIdentical([1, 2, [3, 2],[1, 2, [3, 2]]])

Here is better (in my opinion) version:

Array.prototype.compare = function (array) {
    // if the other array is a falsy value, return
    if (!array)
        return false;

    // compare lengths - can save a lot of time
    if (this.length != array.length)
        return false;

    this.sort();
    array.sort();
    for (var i = 0; i < this.length; i++) {
        // Check if we have nested arrays
        if (this[i] instanceof Array && array[i] instanceof Array) {
            // recurse into the nested arrays
            if (!this[i].compare(array[i]))
                return false;
        }
        else if (this[i] != array[i]) {
            // Warning - two different object instances will never be equal: {x:20} != {x:20}

This is a useful article which graphically shows the explanation of the reset command.

https://git-scm.com/docs/git-reset

Reset --hard can be quite dangerous as it overwrites your working copy without checking, so if you haven't commited the file at all, it is gone.

As for Source tree, there is no way I know of to undo commits. It would most likely use reset under the covers anyway

In your second statement

import {FriendCard} from './../pages/FriendCard'

you are telling typescript to import the FriendCard class from the file './pages/FriendCard'

Your FriendCard file is exporting a variable and that variable is referencing the anonymous function.

You have two options here. If you want to do this in a typed way you can refactor your module to be typed (option 1) or you can import the anonymous function and add a d.ts file. See https://github.com/Microsoft/TypeScript/issues/3019 for more details. about why you need to add the file.

Option 1

Refactor the Friend card js file to be typed.

export class FriendCard {
webElement: any;
menuButton: any;
serialNumber: any;

constructor(card) {
    this.webElement = card;
    this.menuButton;
    this.serialNumber;
}



getAsWebElement = function () {
    return this.webElement;
};

clickMenuButton = function () {
    this.menuButton.click();
};

setSerialNumber = function (numberOfElements) {
    this.serialNumber = numberOfElements + 1;
    this.menuButton = element(by.xpath('.//*[@id=\'mCSB_2_container\']/li[' + serialNumber + ']/ng-include/div/div[2]/i'));
};

deleteFriend = function () {
    element(by.css('[ng-click="deleteFriend(person);"]')).click();
    element(by.css('[ng-click="confirm()"]')).click();
}
};

Option 2

You can import the anonymous function

 import * as FriendCard from module("./FriendCardJs");

There are a few options for a d.ts file definition. This answer seems to be the most complete: How do you produce a .d.ts "typings" definition file from an existing JavaScript library?

The PHP manual explains both quite well:

http://php.net/manual/en/reserved.variables.server.php # REQUEST_URI

http://php.net/manual/en/reserved.variables.get.php # for the $_GET["q"] variable

You can't call a constructor as if it was a normal method, you can only call it with new to create a new object:

Kid newKid = new Kid(this.name, this.height, this.bDay);

But constructing a new object from your toString() method is not what you want to be doing.

A 32-bit process is still limited to the same constraints in a 64-bit OS. The issue is that memory pointers are only 32-bits wide, so the program can't assign/resolve any memory address larger than 32 bits.

You can simply check out a new branch, and then commit:

git checkout -b my_new_branch
git commit

Checking out the new branch will not discard your changes.

In command line it's better to use REG tool rather than REGEDIT:

REG IMPORT yourfile.reg

REG is designed for console mode, while REGEDIT is for graphical mode. This is why running regedit.exe /S yourfile.reg is a bad idea, since you will not be notified if the there's an error, whereas REG Tool will prompt:

>  REG IMPORT missing_file.reg

ERROR: Error opening the file. There may be a disk or file system error.

>  %windir%\System32\reg.exe /?

Had the same problem. Turned out it was caused by iptables connection tracking on the upstream server. After removing --state NEW,ESTABLISHED,RELATED from the firewall script and flushing with conntrack -F the problem was gone.

For other people looking for this solution, just use: ~~ without parseInt, it is the cleanest mode.

var a = 'hello';
var b = ~~a;

If NaN, it will return 0 instead.

OBS. This solution apply only for integers

My 2 cents - you don't need to store the excel as a physical file on the server - instead, store it in the (Session) Cache. Use a uniquely generated name for your Cache variable (that stores that excel file) - this will be the return of your (initial) ajax call. This way you don't have to deal with file access issues, managing (deleting) the files when not needed, etc. and, having the file in the Cache, is faster to retrieve it.

The first parameter is the String to encode; the second is the name of the character encoding to use (e.g., UTF-8).

I see that the question is an old one. If anyone stumbles upon this in the future, I think this is one simple way of doing it. Keep the properties file in your project folder.

        FileReader reader = new FileReader("Config.properties");

        Properties prop = new Properties();
        prop.load(reader);

If you use Animator for make animation you can

anim (directory) -> fade_out.xml

<?xml version="1.0" encoding="UTF-8"?>
<objectAnimator
    android:propertyName="alpha"
    android:valueFrom="0"
    android:valueTo="1"
    xmlns:android="http://schemas.android.com/apk/res/android"/>

In java

Animator animator = AnimatorInflater.loadAnimator(context, R.animator.fade_out);
animator.setTarget(the_view_you_want_to_animation);
animator.setDuration(1000);
animator.start();

Other way to make animation fade out with only java code is

ObjectAnimator fadeOut = ObjectAnimator.ofFloat(the_view_you_want_to_animation, "alpha",  1f, 0);
fadeOut.setDuration(2000);
fadeOut.start();

I am very late to this but I want to mention that that new is actually unsafe in the Obj-C with Swift world. Swift will only create a default init method if you do not create any other initializer. Calling new on a swift class with a custom initializer will cause a crash. If you use alloc/init then the compiler will properly complain that init does not exist.

Check your project by running gcloud config list Then gcloud config set "project name"

    char *p = strtok (buf, "/");
    char *array[3];

    while (p != NULL)
    {
        array[i++] = p;
        p = strtok (NULL, "/");
    }

    for (i = 0; i < 3; ++i) 
        printf("%s\n", array[i]);

    return 0;
}

You don't need that sort of solution for string literals, since they are concatenated at the language level, and it wouldn't work anyway because "s""1" isn't a valid preprocessor token.

[Edit: In response to the incorrect "Just for the record" comment below that unfortunately received several upvotes, I will reiterate the statement above and observe that the program fragment

#define PPCAT_NX(A, B) A ## B
PPCAT_NX("s", "1")

produces this error message from the preprocessing phase of gcc: error: pasting ""s"" and ""1"" does not give a valid preprocessing token

]

However, for general token pasting, try this:

/*
 * Concatenate preprocessor tokens A and B without expanding macro definitions
 * (however, if invoked from a macro, macro arguments are expanded).
 */
#define PPCAT_NX(A, B) A ## B

/*
 * Concatenate preprocessor tokens A and B after macro-expanding them.
 */
#define PPCAT(A, B) PPCAT_NX(A, B)

Then, e.g., both PPCAT_NX(s, 1) and PPCAT(s, 1) produce the identifier s1, unless s is defined as a macro, in which case PPCAT(s, 1) produces <macro value of s>1.

Continuing on the theme are these macros:

/*
 * Turn A into a string literal without expanding macro definitions
 * (however, if invoked from a macro, macro arguments are expanded).
 */
#define STRINGIZE_NX(A) #A

/*
 * Turn A into a string literal after macro-expanding it.
 */
#define STRINGIZE(A) STRINGIZE_NX(A)

Then,

#define T1 s
#define T2 1
STRINGIZE(PPCAT(T1, T2)) // produces "s1"

By contrast,

STRINGIZE(PPCAT_NX(T1, T2)) // produces "T1T2"
STRINGIZE_NX(PPCAT_NX(T1, T2)) // produces "PPCAT_NX(T1, T2)"

#define T1T2 visit the zoo
STRINGIZE(PPCAT_NX(T1, T2)) // produces "visit the zoo"
STRINGIZE_NX(PPCAT(T1, T2)) // produces "PPCAT(T1, T2)"

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

Check if IIS server installed the URL rewrite feature.
If it is not installed then make sure your web.config file don't have the URL rewrite related configuration

<!-- Make sure don't have below config, if server have not installed url rewrite feature. -->

    <rule name="Fail bad requests">
      <match url=".*"/> ...

Some time we copied the config from legacy server and straight away deploy to brand new server, then we may encounter such kind of 500 issue.

A void* does not mean anything. It is a pointer, but the type that it points to is not known.

It's not that it can return "anything". A function that returns a void* generally is doing one of the following:

• It is dealing in unformatted memory. This is what operator new and malloc return: a pointer to a block of memory of a certain size. Since the memory does not have a type (because it does not have a properly constructed object in it yet), it is typeless. IE: void.
• It is an opaque handle; it references a created object without naming a specific type. Code that does this is generally poorly formed, since this is better done by forward declaring a struct/class and simply not providing a public definition for it. Because then, at least it has a real type.
• It returns a pointer to storage that contains an object of a known type. However, that API is used to deal with objects of a wide variety of types, so the exact type that a particular call returns cannot be known at compile time. Therefore, there will be some documentation explaining when it stores which kinds of objects, and therefore which type you can safely cast it to.

This construct is nothing like dynamic or object in C#. Those tools actually know what the original type is; void* does not. This makes it far more dangerous than any of those, because it is very easy to get it wrong, and there's no way to ask if a particular usage is the right one.

And on a personal note, if you see code that uses void*'s "often", you should rethink what code you're looking at. void* usage, especially in C++, should be rare, used primary for dealing in raw memory.

In the for, you have an iteration, then for each element of that loop which probably is a scalar, has no index. When each element is an empty array, single variable, or scalar and not a list or array you cannot use indices.

As a more general solution (but ASCII only!), to include any other separators between words (like commas and semicolons), I suggest:

String s = "I want to walk my dog, cat, and tarantula; maybe even my tortoise.";
String[] words = s.split("\\W+");

The regex means that the delimiters will be anything that is not a word [\W], in groups of at least one [+]. Because [+] is greedy, it will take for instance ';' and ' ' together as one delimiter.

If you like to write CoffeeScript you could do:

hello = "foo"
my_string = "I pity the #{hello}"

CoffeeScript actually IS javascript, but with a much better syntax.

For an overview of CoffeeScript check this beginner's guide.

It's as simple as this:

unsigned int foo;
int bar = 10;

foo = (unsigned int)bar;

Or vice versa...

If you are just placing the code on the page, usually the code behind will get an auto generated field you to use like @Oded has shown.

In other cases, you can always use this code:

Label myLabel = this.FindControl("myLabel") as Label; // this is your Page class

if(myLabel != null)
   myLabel.Text = "SomeText";

You need to prevent the default behaviour. You can either use e.preventDefault() or return false; In this case, the best thing is, you can use return false; here:

<form onsubmit="completeAndRedirect(); return false;">

If the lines in the file end with \r\n\000 then what works is to delete the \n\000 then replace the \r with \n.

tr -d '\n\000' <infile | tr '\r' '\n' >outfile

          return 0;
    }
}
class Class2 extends Class1 {
    public static int Method1(){
   System.out.println("false");
          return 1;
    }

}
public class Mai {
    public static void main(String[] args){
           Class2 c=new Class2();
          //Must explicitly chose Method1 from Class1 or Class2
          //Class1.Method1();
          c.Method1();
    }
}

Or to use this in Java 8:

  Files.newDirectoryStream( directory ).forEach( file -> {
    try { Files.delete( file ); }
    catch ( IOException e ) { throw new UncheckedIOException(e); }
  } );
}
catch ( IOException e ) {

I want to select the text of a string that is located after the occurrence of substring

You could use:

substring-after($string,$match)

If you want a subtring of the above with some length then use:

substring(substring-after($string,$match),1,$length)

But problems begin if there is no ocurrence of the matching substring... So, if you want a substring with specific length located after the occurrence of a substring, or from the whole string if there is no match, you could use:

substring(substring-after($string,substring-before($string,$match)),
          string-length($match) * contains($string,$match) + 1,
          $length) 

In your references click on the EntitiyFramework . Go to properties and set the specific version to False. It worked for me.

In Laravel 5.1+, you can use the value() instead of pluck.

To get first occurence, You can either use

DB::table('users')->value('name');

or use,

DB::table('users')->where('id', 1)->pluck('name')->first();

Simplest to remember (not as pretty as Keras):

print(model)

This also work:

repr(model)

If you just want the number of parameters:

sum([param.nelement() for param in model.parameters()])

From: Is there similar pytorch function as model.summary() as keras? (forum.PyTorch.org)

You can also use the following format

strtotime("-3 days", time());
strtotime("+1 day", strtotime($date));

You can stack changes this way:

strtotime("+1 day", strtotime("+1 year", strtotime($date)));

Note the difference between this approach and the one in other answers: instead of concatenating the values +1 day and <timestamp>, you can just pass in the timestamp as the second parameter of strtotime.

You can check your eav_attributes table to find the relevant attribute IDs for each image role, such as;

Then you can use those to set whichever role to any other role for all products like so;

UPDATE catalog_product_entity_varchar AS `v` INNER JOIN (SELECT `value`,`entity_id` FROM `catalog_product_entity_varchar` WHERE `attribute_id`=86) AS `j` ON `j`.`entity_id`=`v`.entity_id SET `v`.`value`=j.`value` WHERE `v`.attribute_id = 85 AND `v`.`entity_id`=`j`.`entity_id`

The above will set all your 'base' roles to the 'small' image of the same product.

Since the loop below only modifies elements already seen, it would be considered acceptable:

a = ['a',' b', 'c ', ' d ']

for i, s in enumerate(a):
    a[i] = s.strip()

print(a) # -> ['a', 'b', 'c', 'd']

Which is different from:

a[:] = [s.strip() for s in a]

in that it doesn't require the creation of a temporary list and an assignment of it to replace the original, although it does require more indexing operations.

Caution: Although you can modify entries this way, you can't change the number of items in the list without risking the chance of encountering problems.

Here's an example of what I mean—deleting an entry messes-up the indexing from that point on:

b = ['a', ' b', 'c ', ' d ']

for i, s in enumerate(b):
    if s.strip() != b[i]:  # leading or trailing whitespace?
        del b[i]

print(b)  # -> ['a', 'c ']  # WRONG!

(The result is wrong because it didn't delete all the items it should have.)

Update

Since this is a fairly popular answer, here's how to effectively delete entries "in-place" (even though that's not exactly the question):

b = ['a',' b', 'c ', ' d ']

b[:] = [entry for entry in b if entry.strip() == entry]

print(b)  # -> ['a']  # CORRECT

CountDownLatch countDownLatch = new CountDownLatch(1);
ExecutorService executorService = ExecutorService executorService = Executors.newSingleThreadExecutor();
executorService.execute(() -> {
    Future<?> future = executorService.submit(() -> {
        System.out.println("generated task");
    });
    countDownLatch.countDown();
    try {
        future.get();
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (ExecutionException e) {
         e.printStackTrace();

I would say using the data- attribute to match the headers with the elements inside it. Fiddle : http://jsfiddle.net/GbRAZ/1/

A preview of the HTML alteration :

   <tr class="header" id="header1">
    <td colspan="2">Header</td>
   </tr>
   <tr data-for="header1" style="display:none">
     <td>data</td>
     <td>data</td>
   </tr>
   <tr data-for="header1" style="display:none">
     <td>data</td>
     <td>data</td>
   </tr>

JS code :

$(".header").click(function () {
   $("[data-for="+this.id+"]").slideToggle("slow");
});

EDIT: But, it involves some HTML changes. so I dunno if thats what you wanted. A better way to structure this would be using <th> or by changing the entire html to use ul, ol, etc or even a div > span setup.

in your css file add this....

a:hover {
 cursor:pointer;
}

if you don't have a css file, add this to the HEAD of your HTML page

<style type="text/css">
 a:hover {
  cursor:pointer;
 }
</style>

also you can use the href="" attribute by returning false at the end of your javascript.

<a href="" onclick="doSomething(); return false;">a link</a>

this is good for many reasons. SEO or if people don't have javascript, the href="" will work. e.g.

<a href="nojavascriptpage.html" onclick="doSomething(); return false;">a link</a>

@see http://www.alistapart.com/articles/behavioralseparation

Edit: Worth noting @BalusC's answer where he mentions :hover is not necessary for the OP's use case. Although other style can be add with the :hover selector.

When you create an App, a file called styles.xml will be created in your res/values folder. If you change the styles, you can change the background, text color, etc for all your layouts. That way you don’t have to go into each individual layout and change the it manually.

styles.xml:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.AppBaseTheme" parent="@android:style/Theme.Light">
    <item name="android:editTextColor">#295055</item> 
    <item name="android:textColorPrimary">#295055</item>
    <item name="android:textColorSecondary">#295055</item>
    <item name="android:textColorTertiary">#295055</item>
    <item name="android:textColorPrimaryInverse">#295055</item>
    <item name="android:textColorSecondaryInverse">#295055</item>
    <item name="android:textColorTertiaryInverse">#295055</item>

     <item name="android:windowBackground">@drawable/custom_background</item>        
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

parent="@android:style/Theme.Light" is Google’s native colors. Here is a reference of what the native styles are: https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/themes.xml

The default Android style is also called “Theme”. So you calling it Theme probably confused the program.

name="Theme.AppBaseTheme" means that you are creating a style that inherits all the styles from parent="@android:style/Theme.Light". This part you can ignore unless you want to inherit from AppBaseTheme again. = <style name="AppTheme" parent="AppBaseTheme">

@drawable/custom_background is a custom image I put in the drawable’s folder. It is a 300x300 png image.

#295055 is a dark blue color.

My code changes the background and text color. For Button text, please look through Google’s native stlyes (the link I gave u above).

Then in Android Manifest, remember to include the code:

<application
android:theme="@style/Theme.AppBaseTheme">

Normally, IIS would use the process identity (the user account it is running the worker process as) to access protected resources like file system or network.

With passthrough authentication, IIS will attempt to use the actual identity of the user when accessing protected resources.

If the user is not authenticated, IIS will use the application pool identity instead. If pool identity is set to NetworkService or LocalSystem, the actual Windows account used is the computer account.

The IIS warning you see is not an error, it's just a warning. The actual check will be performed at execution time, and if it fails, it'll show up in the log.

Please try the given code below, hope it will helpful to you,

    public static int frequency(String s1,String s2)
    {

        int count=0;

        char ch1[]=s2.toCharArray();
        for (int i=0;i<ch.length-1; i++)

                {
                    count=1;
                    count++;
                }





        }
        }
        return count;


    }

To add to jensendp's answer:

I would pass the entity to a user created model and use the values from that entity to set the values in your newly created model. For example:

public class UserInformation {
   public string Name { get; set; }
   public int Age { get; set; }

   public UserInformation(UserEntity user) {
      this.Name = user.name;
      this.Age = user.age;
   }
}

Then change your return type to: IEnumerable<UserInformation>

use setTag();

like this:

@Override    
public void onClick(View v) {     
    int tag = (Integer) v.getTag();     
    switch (tag) {     
    case 1:     
        System.out.println("button1 click");     
        break;     
    case 2:     
        System.out.println("button2 click");     
       break;   
    }     
}     

aggfunc=pd.Series.nunique will only count unique values for a series - in this case count the unique values for a column. But this doesn't quite reflect as an alternative to aggfunc='count'

For simple counting, it better to use aggfunc=pd.Series.count

git submodule foreach --recursive git checkout .

This didn't do the trick for me but it gave me a list of files (in my case only one) that had been changed in the submodule (without me doing anything there).

So I could head over to the submodule and git status showed me that my HEAD was detached -> git checkout master, git status to see the modified file once again, git checkout >filename<, git pull and everything fine again.

There is no such thing as importing in MS SQL. I understand what you mean. It is so simple. Whenever you get/have a something.SQL file, you should just double click and it will directly open in your MS SQL Studio.

Send XML requests with the raw data type, then set the Content-Type to text/xml.

1. After creating a request, use the dropdown to change the request type to POST.

   

2. Open the Body tab and check the data type for raw.

   

3. Open the Content-Type selection box that appears to the right and select either XML (application/xml) or XML (text/xml)

   

4. Enter your raw XML data into the input field below

   

5. Click Send to submit your XML Request to the specified server.

   

foo.GetColumnValues(dm.mainColumn, typeof(int));
foo.GetColumnValues(dm.mainColumn, typeof(string));

Or using generics:

foo.GetColumnValues<int>(dm.mainColumn);
foo.GetColumnValues<string>(dm.mainColumn);

Given a version number MAJOR.MINOR.PATCH, increment the:

• MAJOR version when you make incompatible API changes,
• MINOR version when you add functionality in a backwards-compatible manner, and
• PATCH version when you make backwards-compatible bug fixes.

Version Code & Version Name

As you may know, on android you have to define two version fields for an app: the version code (android:versionCode) and the version name (android:versionName). The version code is an incremental integer value that represents the version of the application code. The version name is a string value that represents the “friendly” version name displayed to the users.

using System.Linq;    
list.Where(x=> x.Name == nameToExtract);

Edit: misread question (now all matches)

Sure, use Enumerable.Distinct.

Given a collection of obj (e.g. foo), you'd do something like this:

var distinctTypeIDs = foo.Select(x => x.typeID).Distinct();

You can use %x or %X or %p; all of them are correct.

• If you use %x, the address is given as lowercase, for example: a3bfbc4
• If you use %X, the address is given as uppercase, for example: A3BFBC4

Both of these are correct.

If you use %x or %X it's considering six positions for the address, and if you use %p it's considering eight positions for the address. For example:

I used to use the easy_install pip==1.2.1 workaround but I randomly found that if you're having this bug, you probably installed a 32bit version of python.

If you install a 64bit version of it by installing it from the source and then build you virtualenv upon it, you wont have that pip bug anymore.

Actually, the erase function works for two profiles:

• Removing a single element

  iterator erase (iterator position);
  

• Removing a range of elements

  iterator erase (iterator first, iterator last);
  

Since std::vec.begin() marks the start of container and if we want to delete the ith element in our vector, we can use:

vec.erase(vec.begin() + index);

If you look closely, vec.begin() is just a pointer to the starting position of our vector and adding the value of i to it increments the pointer to i position, so instead we can access the pointer to the ith element by:

&vec[i]

So we can write:

vec.erase(&vec[i]); // To delete the ith element

There is no way to automatically set CMAKE_PREFIX_PATH in a way you want. I see following ways to solve this problem:

1. Put all libraries files in the same dir. That is, include/ would contain headers for all libs, lib/ - binaries, etc. FYI, this is common layout for most UNIX-like systems.

2. Set global environment variable CMAKE_PREFIX_PATH to D:/develop/cmake/libs/libA;D:/develop/cmake/libs/libB;.... When you run CMake, it would aautomatically pick up this env var and populate it's own CMAKE_PREFIX_PATH.

3. Write a wrapper .bat script, which would call cmake command with -D CMAKE_PREFIX_PATH=... argument.

You can use KVO in Swift, but only for dynamic properties of NSObject subclass. Consider that you wanted to observe the bar property of a Foo class. In Swift 4, specify bar as dynamic property in your NSObject subclass:

class Foo: NSObject {
    @objc dynamic var bar = 0
}

You can then register to observe changes to the bar property. In Swift 4 and Swift 3.2, this has been greatly simplified, as outlined in Using Key-Value Observing in Swift:

class MyObject {
    private var token: NSKeyValueObservation

    var objectToObserve = Foo()

    init() {
        token = objectToObserve.observe(\.bar) { [weak self] object, change in  // the `[weak self]` is to avoid strong reference cycle; obviously, if you don't reference `self` in the closure, then `[weak self]` is not needed
            print("bar property is now \(object.bar)")
        }
    }
}

Note, in Swift 4, we now have strong typing of keypaths using the backslash character (the \.bar is the keypath for the bar property of the object being observed). Also, because it's using the completion closure pattern, we don't have to manually remove observers (when the token falls out of scope, the observer is removed for us) nor do we have to worry about calling the super implementation if the key doesn't match. The closure is called only when this particular observer is invoked. For more information, see WWDC 2017 video, What's New in Foundation.

In Swift 3, to observe this, it's a bit more complicated, but very similar to what one does in Objective-C. Namely, you would implement observeValue(forKeyPath keyPath:, of object:, change:, context:) which (a) makes sure we're dealing with our context (and not something that our super instance had registered to observe); and then (b) either handle it or pass it on to the super implementation, as necessary. And make sure to remove yourself as an observer when appropriate. For example, you might remove the observer when it is deallocated:

In Swift 3:

class MyObject: NSObject {
    private var observerContext = 0

    var objectToObserve = Foo()

    override init() {
        super.init()

        objectToObserve.addObserver(self, forKeyPath: #keyPath(Foo.bar), options: [.new, .old], context: &observerContext)
    }

    deinit {
        objectToObserve.removeObserver(self, forKeyPath: #keyPath(Foo.bar), context: &observerContext)
    }

    override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
        guard context == &observerContext else {
            super.observeValue(forKeyPath: keyPath, of: object, change: change, context: context)
            return
        }

        // do something upon notification of the observed object

        print("\(keyPath): \(change?[.newKey])")
    }

}

Note, you can only observe properties that can be represented in Objective-C. Thus, you cannot observe generics, Swift struct types, Swift enum types, etc.

For a discussion of the Swift 2 implementation, see my original answer, below.

Using the dynamic keyword to achieve KVO with NSObject subclasses is described in the Key-Value Observing section of the Adopting Cocoa Design Conventions chapter of the Using Swift with Cocoa and Objective-C guide:

Key-value observing is a mechanism that allows objects to be notified of changes to specified properties of other objects. You can use key-value observing with a Swift class, as long as the class inherits from the NSObject class. You can use these three steps to implement key-value observing in Swift.

1. Add the dynamic modifier to any property you want to observe. For more information on dynamic, see Requiring Dynamic Dispatch.

   class MyObjectToObserve: NSObject {
       dynamic var myDate = NSDate()
       func updateDate() {
           myDate = NSDate()
       }
   }
   

2. Create a global context variable.

   private var myContext = 0
   

3. Add an observer for the key-path, and override the observeValueForKeyPath:ofObject:change:context: method, and remove the observer in deinit.

   class MyObserver: NSObject {
       var objectToObserve = MyObjectToObserve()
       override init() {
           super.init()
           objectToObserve.addObserver(self, forKeyPath: "myDate", options: .New, context: &myContext)
       }
   
       override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>) {
           if context == &myContext {
               if let newValue = change?[NSKeyValueChangeNewKey] {
                   print("Date changed: \(newValue)")
               }
           } else {
               super.observeValueForKeyPath(keyPath, ofObject: object, change: change, context: context)
           }
       }
   
       deinit {
           objectToObserve.removeObserver(self, forKeyPath: "myDate", context: &myContext)
       }
   }
   

[Note, this KVO discussion has subsequently been removed from the Using Swift with Cocoa and Objective-C guide, which has been adapted for Swift 3, but it still works as outlined at the top of this answer.]

It's worth noting that Swift has its own native property observer system, but that's for a class specifying its own code that will be performed upon observation of its own properties. KVO, on the other hand, is designed to register to observe changes to some dynamic property of some other class.

If should be if. Your program should look like this:

answer = raw_input("Is the information correct? Enter Y for yes or N for no")
if answer.upper() == 'Y':
    print("this will do the calculation")
else:
    exit()

Note also that the indentation is important, because it marks a block in Python.

C++ has no built-in concepts of interfaces. You can implement it using abstract classes which contains only pure virtual functions. Since it allows multiple inheritance, you can inherit this class to create another class which will then contain this interface (I mean, object interface :) ) in it.

An example would be something like this -

class Interface
{
public:
    Interface(){}
    virtual ~Interface(){}
    virtual void method1() = 0;    // "= 0" part makes this method pure virtual, and
                                   // also makes this class abstract.
    virtual void method2() = 0;
};

class Concrete : public Interface
{
private:
    int myMember;

public:
    Concrete(){}
    ~Concrete(){}
    void method1();
    void method2();
};

// Provide implementation for the first method
void Concrete::method1()
{
    // Your implementation
}

// Provide implementation for the second method
void Concrete::method2()
{
    // Your implementation
}

int main(void)
{
    Interface *f = new Concrete();

    f->method1();
    f->method2();

    delete f;

    return 0;
}

String

The String class represents character strings. All string literals in Java program, such as "abc" are implemented as instances of this class.

String objects are immutable once they are created we can't change. (Strings are constants)

• If a String is created using constructor or method then those strings will be stored in Heap Memory as well as SringConstantPool. But before saving in pool it invokes intern() method to check object availability with same content in pool using equals method. If String-copy is available in the Pool then returns the reference. Otherwise, String object is added to the pool and returns the reference.

  • The Java language provides special support for the string concatenation operator (+), and for conversion of other objects to strings. String concatenation is implemented through the StringBuilder(or StringBuffer) class and its append method.

  String heapSCP = new String("Yash");
  heapSCP.concat(".");
  heapSCP = heapSCP + "M";
  heapSCP = heapSCP + 777;
  
  // For Example: String Source Code 
  public String concat(String str) {
      int otherLen = str.length();
      if (otherLen == 0) {
          return this;
      }
      int len = value.length;
      char buf[] = Arrays.copyOf(value, len + otherLen);
      str.getChars(buf, len);
      return new String(buf, true);
  }
  

• String literals are stored in StringConstantPool.

  String onlyPool = "Yash";
  

StringBuilder and StringBuffer are mutable sequence of characters. That means one can change the value of these object's. StringBuffer has the same methods as the StringBuilder, but each method in StringBuffer is synchronized so it is thread safe.

• StringBuffer and StringBuilder data can only be created using new operator. So, they get stored in Heap memory.

• Instances of StringBuilder are not safe for use by multiple threads. If such synchronization is required then it is recommended that StringBuffer be used.

  StringBuffer threadSafe = new StringBuffer("Yash");
  threadSafe.append(".M");
  threadSafe.toString();
  
  StringBuilder nonSync = new StringBuilder("Yash");
  nonSync.append(".M");
  nonSync.toString();
  

• StringBuffer and StringBuilder are having a Special methods like., replace(int start, int end, String str) and reverse().

  NOTE: StringBuffer and SringBuilder are mutable as they provides the implementation of Appendable Interface.

When to use which one.

• If a you are not going to change the value every time then its better to Use String Class. As part of Generics if you want to Sort Comparable<T> or compare a values then go for String Class.

  //ClassCastException: java.lang.StringBuffer cannot be cast to java.lang.Comparable
  Set<StringBuffer> set = new TreeSet<StringBuffer>();
  set.add( threadSafe );
  System.out.println("Set : "+ set);
  

• If you are going to modify the value every time the go for StringBuilder which is faster than StringBuffer. If multiple threads are modifying the value the go for StringBuffer.

I figured this one out. I know this will help someone someday.

You can see the working jsFiddle here.

You could use regular expressions to replace the '\n' or '\n\r' characters with '<br />'.

you have this:

var h1 = document.createElement("h1");

h1.textContent = "This is a very long string and I would like to insert a carriage return HERE...
moreover, I would like to insert another carriage return HERE... 
so this text will display in a new line";

you can replace your characters like this:

h1.innerHTML = h1.innerHTML.replace(/\n\r?/g, '<br />');

I think it may be the sudo has no access to get ORACLE_HOME.You can do like this.

sudo visudo

modify the text add

Defaults env_keep += "ORACLE_HOME"

then

sudo python setup.py build install

In short

Summary

In its simplest form, this technique aims to wrap code inside a function scope.

It helps decreases chances of:

• clashing with other applications/libraries
• polluting superior (global most likely) scope

It does not detect when the document is ready - it is not some kind of document.onload nor window.onload

It is commonly known as an Immediately Invoked Function Expression (IIFE) or Self Executing Anonymous Function.

Code Explained

var someFunction = function(){ console.log('wagwan!'); };

(function() {                   /* function scope starts here */
  console.log('start of IIFE');

  var myNumber = 4;             /* number variable declaration */
  var myFunction = function(){  /* function variable declaration */
    console.log('formidable!'); 
  };
  var myObject = {              /* object variable declaration */
    anotherNumber : 1001, 
    anotherFunc : function(){ console.log('formidable!'); }
  };
  console.log('end of IIFE');
})();                           /* function scope ends */

someFunction();            // reachable, hence works: see in the console
myFunction();              // unreachable, will throw an error, see in the console
myObject.anotherFunc();    // unreachable, will throw an error, see in the console

In the example above, any variable defined in the function (i.e. declared using var) will be "private" and accessible within the function scope ONLY (as Vivin Paliath puts it). In other words, these variables are not visible/reachable outside the function. See live demo.

Javascript has function scoping. "Parameters and variables defined in a function are not visible outside of the function, and that a variable defined anywhere within a function is visible everywhere within the function." (from "Javascript: The Good Parts").

More details

Alternative Code

In the end, the code posted before could also be done as follows:

var someFunction = function(){ console.log('wagwan!'); };

var myMainFunction = function() {
  console.log('start of IIFE');

  var myNumber = 4;
  var myFunction = function(){ console.log('formidable!'); };
  var myObject = { 
    anotherNumber : 1001, 
    anotherFunc : function(){ console.log('formidable!'); }
  };
  console.log('end of IIFE');
};

myMainFunction();          // I CALL "myMainFunction" FUNCTION HERE
someFunction();            // reachable, hence works: see in the console
myFunction();              // unreachable, will throw an error, see in the console
myObject.anotherFunc();    // unreachable, will throw an error, see in the console

See live demo.

The Roots

Iteration 1

One day, someone probably thought "there must be a way to avoid naming 'myMainFunction', since all we want is to execute it immediately."

If you go back to the basics, you find out that:

• expression: something evaluating to a value. i.e. 3+11/x
• statement: line(s) of code doing something BUT it does not evaluate to a value. i.e. if(){}

Similarly, function expressions evaluate to a value. And one consequence (I assume?) is that they can be immediately invoked:

 var italianSayinSomething = function(){ console.log('mamamia!'); }();

So our more complex example becomes:

var someFunction = function(){ console.log('wagwan!'); };

var myMainFunction = function() {
  console.log('start of IIFE');

  var myNumber = 4;
  var myFunction = function(){ console.log('formidable!'); };
  var myObject = { 
    anotherNumber : 1001, 
    anotherFunc : function(){ console.log('formidable!'); }
  };
  console.log('end of IIFE');
}();

someFunction();            // reachable, hence works: see in the console
myFunction();              // unreachable, will throw an error, see in the console
myObject.anotherFunc();    // unreachable, will throw an error, see in the console

See live demo.

Iteration 2

The next step is the thought "why have var myMainFunction = if we don't even use it!?".

The answer is simple: try removing this, such as below:

 function(){ console.log('mamamia!'); }();

See live demo.

It won't work because "function declarations are not invokable".

The trick is that by removing var myMainFunction = we transformed the function expression into a function declaration. See the links in "Resources" for more details on this.

The next question is "why can't I keep it as a function expression with something other than var myMainFunction =?

The answer is "you can", and there are actually many ways you could do this: adding a +, a !, a -, or maybe wrapping in a pair of parenthesis (as it's now done by convention), and more I believe. As example:

 (function(){ console.log('mamamia!'); })(); // live demo: jsbin.com/zokuwodoco/1/edit?js,console.

or

 +function(){ console.log('mamamia!'); }(); // live demo: jsbin.com/wuwipiyazi/1/edit?js,console

or

 -function(){ console.log('mamamia!'); }(); // live demo: jsbin.com/wejupaheva/1/edit?js,console

• What does the exclamation mark do before the function?
• JavaScript plus sign in front of function name

So once the relevant modification is added to what was once our "Alternative Code", we return to the exact same code as the one used in the "Code Explained" example

var someFunction = function(){ console.log('wagwan!'); };

(function() {
  console.log('start of IIFE');

  var myNumber = 4;
  var myFunction = function(){ console.log('formidable!'); };
  var myObject = { 
    anotherNumber : 1001, 
    anotherFunc : function(){ console.log('formidable!'); }
  };
  console.log('end of IIFE');
})();

someFunction();            // reachable, hence works: see in the console
myFunction();              // unreachable, will throw an error, see in the console
myObject.anotherFunc();    // unreachable, will throw an error, see in the console

Demystifying Scopes

One thing one might wonder is "what happens when you do NOT define the variable 'properly' inside the function -- i.e. do a simple assignment instead?"

(function() {
  var myNumber = 4;             /* number variable declaration */
  var myFunction = function(){  /* function variable declaration */
    console.log('formidable!'); 
  };
  var myObject = {              /* object variable declaration */
    anotherNumber : 1001, 
    anotherFunc : function(){ console.log('formidable!'); }
  };
  myOtherFunction = function(){  /* oops, an assignment instead of a declaration */
    console.log('haha. got ya!');
  };
})();
myOtherFunction();         // reachable, hence works: see in the console
window.myOtherFunction();  // works in the browser, myOtherFunction is then in the global scope
myFunction();              // unreachable, will throw an error, see in the console

See live demo.

Basically, if a variable that was not declared in its current scope is assigned a value, then "a look up the scope chain occurs until it finds the variable or hits the global scope (at which point it will create it)".

When in a browser environment (vs a server environment like nodejs) the global scope is defined by the window object. Hence we can do window.myOtherFunction().

My "Good practices" tip on this topic is to always use var when defining anything: whether it's a number, object or function, & even when in the global scope. This makes the code much simpler.

Note:

• javascript does not have block scope (Update: block scope local variables added in ES6.)
• javascript has only function scope & global scope (window scope in a browser environment)

Next Steps

Once you get this IIFE concept, it leads to the module pattern, which is commonly done by leveraging this IIFE pattern. Have fun :)

Why not this, it's easy:

extract($_POST);

I would suggest using a different approach. Add a button on the webpage that will copy the content of the table to the clipboard, with TAB chars between columns and newlines between rows. This way the "paste" function in Excel should work correctly and your web application will also work with many browsers and on many operating systems (linux, mac, mobile) and users will be able to use the data also with other spreadsheets or word processing programs.

The only tricky part is to copy to the clipboard because many browsers are security obsessed on this. A solution is to prepare the data already selected in a textarea, and show it to the user in a modal dialog box where you tell the user to copy the text (some will need to type Ctrl-C, others Command-c, others will use a "long touch" or a popup menu).

It would be nicer to have a standard copy-to-clipboard function that possibly requests a user confirmation... but this is not the case, unfortunately.

change Settings Manager >> Preferred Applications >> Utilities

A simpler but equally effective option would be:

+ theme_bw(base_size=X)

This might help:

<input type="number" step="1" pattern="\d+" />

step is for convenience (and could be set to another integer), but pattern does some actual enforcing.

Note that since pattern matches the whole expression, it wasn't necessary to express it as ^\d+$.

Even with this outwardly tight regular expression, Chrome and Firefox's implementations, interestingly allow for e here (presumably for scientific notation) as well as - for negative numbers, and Chrome also allows for . whereas Firefox is tighter in rejecting unless the . is followed by 0's only. (Firefox marks the field as red upon the input losing focus whereas Chrome doesn't let you input disallowed values in the first place.)

Since, as observed by others, one should always validate on the server (or on the client too, if using the value locally on the client or wishing to prevent the user from a roundtrip to the server).

You can achieve that with just one line code that simplify that:

$('#divs').get(0).outerHTML;

As simple as that.

mikej's answer was very precise and helpful, but the the thing i also wanted to know was how to get current method name in rails.

found out it's possible with self.current_method

easily found at http://www.ruby-forum.com/topic/75258

There are two major performance issues with your code:

• Using Add method
• Using SaveChanges

Using Add method

The Add method becomes only slower and slower at each entity you add.

See: http://entityframework.net/improve-ef-add-performance

For example, adding 10,000 entities via:

• Add (take ~105,000ms)
• AddRange (take ~120ms)

Note: Entities has not been saved yet in the database!

The problem is that the Add method tries to DetectChanges at every entity added while AddRange does it once after all entities have been added to the context.

Common solutions are:

• Use AddRange over Add
• SET AutoDetectChanges to false
• SPLIT SaveChanges in multiple batches

Using SaveChanges

Entity Framework has not been created for Bulk Operations. For every entity you save, a database round-trip is performed.

So, if you want to insert 20,000 records, you will perform 20,000 database round-trip which is INSANE!

There are some third-party libraries supporting Bulk Insert available:

• Z.EntityFramework.Extensions (Recommended)
• EFUtilities
• EntityFramework.BulkInsert

See: Entity Framework Bulk Insert library

Be careful, when choosing a bulk insert library. Only Entity Framework Extensions support all kind of associations and inheritance, and it's the only one still supported.

Disclaimer: I'm the owner of Entity Framework Extensions

This library allows you to perform all bulk operations you need for your scenarios:

• Bulk SaveChanges
• Bulk Insert
• Bulk Delete
• Bulk Update
• Bulk Merge

Example

// Easy to use
context.BulkSaveChanges();

// Easy to customize
context.BulkSaveChanges(bulk => bulk.BatchSize = 100);

// Perform Bulk Operations
context.BulkDelete(customers);
context.BulkInsert(customers);
context.BulkUpdate(customers);

// Customize Primary Key
context.BulkMerge(customers, operation => {
   operation.ColumnPrimaryKeyExpression = 
        customer => customer.Code;
});

EDIT: Answer Question in Comment

Is there a recommend max size for each bulk insert for the library you created

Not too high, not too low. There isn't a particular value that fit in all scenarios since it depends on multiple factors such as row size, index, trigger, etc.

It's normally recommended to be around 4000.

Also is there a way to tie it all in one transaction and not worry about it timing out

You can use Entity Framework transaction. Our library uses the transaction if one is started. But be careful, a transaction that takes too much time come also with problems such as some row/index/table lock.

tl;dr

Instant stop = 
    myUtilDateStart.toInstant()
                   .plus( Duration.ofMinutes( x ) ) 
;

java.time

Other Answers are correct, especially the Answer by Borgwardt. But those Answers use outmoded legacy classes.

The original date-time classes bundled with Java have been supplanted with java.time classes. Perform your business logic in java.time types. Convert to the old types only where needed to work with old code not yet updated to handle java.time types.

If your Calendar is actually a GregorianCalendar you can convert to a ZonedDateTime. Find new methods added to the old classes to facilitate conversion to/from java.time types.

if( myUtilCalendar instanceof GregorianCalendar ) {
    GregorianCalendar gregCal = (GregorianCalendar) myUtilCalendar; // Downcasting from the interface to the concrete class.
    ZonedDateTime zdt = gregCal.toZonedDateTime();  // Create `ZonedDateTime` with same time zone info found in the `GregorianCalendar`
end if 

If your Calendar is not a Gregorian, call toInstant to get an Instant object. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds.

Instant instant = myCal.toInstant();

Similarly, if starting with a java.util.Date object, convert to an Instant. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = myUtilDate.toInstant();

Apply a time zone to get a ZonedDateTime.

ZoneId z = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = instant.atZone( z );

To get a java.util.Date object, go through the Instant.

java.util.Date utilDate = java.util.Date.from( zdt.toInstant() );

For more discussion of converting between the legacy date-time types and java.time, and a nifty diagram, see my Answer to another Question.

Duration

Represent the span of time as a Duration object. Your input for the duration is a number of minutes as mentioned in the Question.

Duration d = Duration.ofMinutes( yourMinutesGoHere );

You can add that to the start to determine the stop.

Instant stop = startInstant.plus( d ); 

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to java.time.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Add a column to the left so that B10 to B20 is your named range Age.

Set A10 to A20 so that A10 = 1, A11= 2,... A20 = 11 and give the range A10 to A20 a name e.g. AgeIndex.

The 5th element can be then found by using an array formula:

=sum( Age * (1 * (AgeIndex = 5) )

As it's an array formula you'll need to press Ctrl + Shift + Return to make it work and not just return. Doing that, the formula will be turned into an array formula:

{=sum( Age * (1 * (AgeIndex = 5) )}

And if you can't repeat the background image (for esthetic reasons), then this handy JQuery plugin will stretch the background image to fit the window.

What about this simple approach. Its working fine for me.

extension UITextField {

    func  charactersLimit(to:Int) {

        if (self.text!.count > to) {
            self.deleteBackward()
        }
    }
}

Then:

someTextField.charactersLimit(to:16)

You can use UNION All clause to perform multiple insert in a table.

ex:

INSERT INTO dbo.MyTable (ID, Name)
SELECT 123, 'Timmy'
UNION ALL
SELECT 124, 'Jonny'
UNION ALL
SELECT 125, 'Sally'

You may try to make the folder which include jsp-s become the source folder of eclipse, that solved the same problem of mine. As below:

1. open project's properties.(right click project, then choose the Properties)
2. choose Java Build Path, select the Source tab, click Add Folder and choose the folder including your jsp-s, OK

Chain both class selectors (without a space in between):

.foo.bar {
    /* Styles for element(s) with foo AND bar classes */
}

If you still have to deal with ancient browsers like IE6, be aware that it doesn't read chained class selectors correctly: it'll only read the last class selector (.bar in this case) instead, regardless of what other classes you list.

To illustrate how other browsers and IE6 interpret this, consider this CSS:

* {
    color: black;
}

.foo.bar {
    color: red;
}

Output on supported browsers is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Not selected, black text [3] -->

Output on IE6 is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Selected, red text [2] -->

Footnotes:

• Supported browsers:
  1. Not selected as this element only has class foo.
  2. Selected as this element has both classes foo and bar.
  3. Not selected as this element only has class bar.
     
     
• IE6:
  1. Not selected as this element doesn't have class bar.
  2. Selected as this element has class bar, regardless of any other classes listed.

You can also solve this issue by removing the value "256m" under the line "-launcher.XXMaxPermSize”.

We selected YourKit Profiler for .NET in my company as it was the best value (price vs. feature). For a small company that wants to have flexible licensing (floating licenses) it was a perfect choice - ANTS was developer seat locket at the time.

Also, it provided us with the ability to attach to the running process which was not possible with dotTrace. Beware though that attaching is not the best option as everything .NET will slow down, but this was the only way to profile .NET applications started by other processes. Feature wise, ANTS and dotTrace were better - but in the end YourKit was good enough.

When using webview as a subview somewhere in scrollview, you can set height constraint to some constant value and later make outlet from it and use it like:

- (void)webViewDidFinishLoad:(UIWebView *)webView {
    webView.scrollView.scrollEnabled = NO;
    _webViewHeight.constant = webView.scrollView.contentSize.height;
}

Caution: This answer shows a truly obscure construction.

If you are using GCC, check out this library. Like in PHP, break can accept the number of nested loops you want to exit. You can write something like this:

for(int i = 0; i < 1000; i++) {
   for(int j = 0; j < 1000; j++) {
       if(condition) {
            // break two nested enclosing loops
            break(2);
       }
   }
}

And you don't need to separate things. All you need to do is including everything in a setTimeOut method:

setTimeout(function () {
    $("#div").addClass("error").delay(1000).removeClass("error");
}, 1000);

WOOCOMMERCE ORDERS IN VERSION 3.0+

Since Woocommerce mega major Update 3.0+ things have changed quite a lot:

• For WC_Order Object, properties can't be accessed directly anymore as before and will throw some errors.
• New WC_Order and WC_Abstract_Order getter and setter methods are now required on the WC_Order object instance.
• Also, there are some New classes for Order items:
  • WC_Order_Item class,
  • WC_Order_Item_Product class,
  • WC_Order_Item_Tax class,
  • WC_Order_Item_Shipping class,
  • WC_Order_Item_Coupon class,
  • WC_Order_Item_Fee class.
• Additionally, WC_Data Abstract class allow to access Order and order items data using get_data(), get_meta_data() and get_meta() methods.

Related:
• How to get Customer details from Order in WooCommerce?
• Get Order items and WC_Order_Item_Product in WooCommerce 3

So the Order items properties will not be accessible as before in a foreach loop and you will have to use these specific getter and setter methods instead.

Using some WC_Order and WC_Abstract_Order methods (example):

// Get an instance of the WC_Order object (same as before)
$order = wc_get_order( $order_id );

$order_id  = $order->get_id(); // Get the order ID
$parent_id = $order->get_parent_id(); // Get the parent order ID (for subscriptions…)

$user_id   = $order->get_user_id(); // Get the costumer ID
$user      = $order->get_user(); // Get the WP_User object

$order_status  = $order->get_status(); // Get the order status (see the conditional method has_status() below)
$currency      = $order->get_currency(); // Get the currency used  
$payment_method = $order->get_payment_method(); // Get the payment method ID
$payment_title = $order->get_payment_method_title(); // Get the payment method title
$date_created  = $order->get_date_created(); // Get date created (WC_DateTime object)
$date_modified = $order->get_date_modified(); // Get date modified (WC_DateTime object)

$billing_country = $order->get_billing_country(); // Customer billing country

// ... and so on ...

For order status as a conditional method (where "the_targeted_status" need to be defined and replaced by an order status to target a specific order status):

if ( $order->has_status('completed') ) {
    // Do something
}

Get and access to the order data properties (in an array of values):

// Get an instance of the WC_Order object
$order = wc_get_order( $order_id );

$order_data = $order->get_data(); // The Order data

$order_id = $order_data['id'];
$order_parent_id = $order_data['parent_id'];
$order_status = $order_data['status'];
$order_currency = $order_data['currency'];
$order_version = $order_data['version'];
$order_payment_method = $order_data['payment_method'];
$order_payment_method_title = $order_data['payment_method_title'];
$order_payment_method = $order_data['payment_method'];
$order_payment_method = $order_data['payment_method'];

## Creation and modified WC_DateTime Object date string ##

// Using a formated date ( with php date() function as method)
$order_date_created = $order_data['date_created']->date('Y-m-d H:i:s');
$order_date_modified = $order_data['date_modified']->date('Y-m-d H:i:s');

// Using a timestamp ( with php getTimestamp() function as method)
$order_timestamp_created = $order_data['date_created']->getTimestamp();
$order_timestamp_modified = $order_data['date_modified']->getTimestamp();

$order_discount_total = $order_data['discount_total'];
$order_discount_tax = $order_data['discount_tax'];
$order_shipping_total = $order_data['shipping_total'];
$order_shipping_tax = $order_data['shipping_tax'];
$order_total = $order_data['total'];
$order_total_tax = $order_data['total_tax'];
$order_customer_id = $order_data['customer_id']; // ... and so on

## BILLING INFORMATION:

$order_billing_first_name = $order_data['billing']['first_name'];
$order_billing_last_name = $order_data['billing']['last_name'];
$order_billing_company = $order_data['billing']['company'];
$order_billing_address_1 = $order_data['billing']['address_1'];
$order_billing_address_2 = $order_data['billing']['address_2'];
$order_billing_city = $order_data['billing']['city'];
$order_billing_state = $order_data['billing']['state'];
$order_billing_postcode = $order_data['billing']['postcode'];
$order_billing_country = $order_data['billing']['country'];
$order_billing_email = $order_data['billing']['email'];
$order_billing_phone = $order_data['billing']['phone'];

## SHIPPING INFORMATION:

$order_shipping_first_name = $order_data['shipping']['first_name'];
$order_shipping_last_name = $order_data['shipping']['last_name'];
$order_shipping_company = $order_data['shipping']['company'];
$order_shipping_address_1 = $order_data['shipping']['address_1'];
$order_shipping_address_2 = $order_data['shipping']['address_2'];
$order_shipping_city = $order_data['shipping']['city'];
$order_shipping_state = $order_data['shipping']['state'];
$order_shipping_postcode = $order_data['shipping']['postcode'];
$order_shipping_country = $order_data['shipping']['country'];

Get the order items and access the data with WC_Order_Item_Product and WC_Order_Item methods:

// Get an instance of the WC_Order object
$order = wc_get_order($order_id);

// Iterating through each WC_Order_Item_Product objects
foreach ($order->get_items() as $item_key => $item ):

    ## Using WC_Order_Item methods ##

    // Item ID is directly accessible from the $item_key in the foreach loop or
    $item_id = $item->get_id();

    ## Using WC_Order_Item_Product methods ##

    $product      = $item->get_product(); // Get the WC_Product object

    $product_id   = $item->get_product_id(); // the Product id
    $variation_id = $item->get_variation_id(); // the Variation id

    $item_type    = $item->get_type(); // Type of the order item ("line_item")

    $item_name    = $item->get_name(); // Name of the product
    $quantity     = $item->get_quantity();  
    $tax_class    = $item->get_tax_class();
    $line_subtotal     = $item->get_subtotal(); // Line subtotal (non discounted)
    $line_subtotal_tax = $item->get_subtotal_tax(); // Line subtotal tax (non discounted)
    $line_total        = $item->get_total(); // Line total (discounted)
    $line_total_tax    = $item->get_total_tax(); // Line total tax (discounted)

    ## Access Order Items data properties (in an array of values) ##
    $item_data    = $item->get_data();

    $product_name = $item_data['name'];
    $product_id   = $item_data['product_id'];
    $variation_id = $item_data['variation_id'];
    $quantity     = $item_data['quantity'];
    $tax_class    = $item_data['tax_class'];
    $line_subtotal     = $item_data['subtotal'];
    $line_subtotal_tax = $item_data['subtotal_tax'];
    $line_total        = $item_data['total'];
    $line_total_tax    = $item_data['total_tax'];

    // Get data from The WC_product object using methods (examples)
    $product        = $item->get_product(); // Get the WC_Product object

    $product_type   = $product->get_type();
    $product_sku    = $product->get_sku();
    $product_price  = $product->get_price();
    $stock_quantity = $product->get_stock_quantity();

endforeach;

So using get_data() method allow us to access to the protected data (associative array mode) …

You have two options, and I'll leave selection up to you.

1. Shared Preferences

   This is a framework unique to Android that allows you to store primitive values (such as int, boolean, and String, although strictly speaking String isn't a primitive) in a key-value framework. This means that you give a value a name, say, "homeScore" and store the value to this key.

   SharedPreferences settings = getApplicationContext().getSharedPreferences(PREFS_NAME, 0);
   SharedPreferences.Editor editor = settings.edit();
   editor.putInt("homeScore", YOUR_HOME_SCORE);
   
   // Apply the edits!
   editor.apply();
   
   // Get from the SharedPreferences
   SharedPreferences settings = getApplicationContext().getSharedPreferences(PREFS_NAME, 0);
   int homeScore = settings.getInt("homeScore", 0);
   

2. Internal Storage

   This, in my opinion, is what you might be looking for. You can store anything you want to a file, so this gives you more flexibility. However, the process can be trickier because everything will be stored as bytes, and that means you have to be careful to keep your read and write processes working together.

   int homeScore;
   byte[] homeScoreBytes;
   
   homeScoreBytes[0] = (byte) homeScore;
   homeScoreBytes[1] = (byte) (homeScore >> 8);  //you can probably skip these two 
   homeScoreBytes[2] = (byte) (homeScore >> 16); //lines, because I've never seen a                   
                                                 //basketball score above 128, it's
                                                 //such a rare occurance.
   
   FileOutputStream outputStream = getApplicationContext().openFileOutput(FILENAME, Context.MODE_PRIVATE);
   outputStream.write(homeScoreBytes);
   outputStream.close();
   

Now, you can also look into External Storage, but I don't recommend that in this particular case, because the external storage might not be there later. (Note that if you pick this, it requires a permission)

Just to clarify my comment (it's illegible in a single line)

I think the best answer is the comment by Mike Chambers in this link (http://www.judahfrangipane.com/blog/2007/02/15/error-2032-stream-error/) by Hunter McMillen.

A note from Mike Chambers:

If you run into this using URLLoader, listen for the:

flash.events.HTTPStatusEvent.HTTP_STATUS

and in AIR :

flash.events.HTTPStatusEvent.HTTP_RESPONSE_STATUS

It should give you some more information (such as the status code being returned from the server).

Since this must have an input element as a parent, you could just use

<input type="text" ng-model="foo" ng-change="myOnChangeFunction()">

Alternatively, you could use the ngModelController and add a function to $formatters, which executes functions on input change. See http://docs.angularjs.org/api/ng.directive:ngModel.NgModelController

.directive("myDirective", function() {
  return {
    restrict: 'A',
    require: 'ngModel',
    link: function(scope, element, attr, ngModel) {
      ngModel.$formatters.push(function(value) {
        // Do stuff here, and return the formatted value.
      });
  };
};

The removeAttr() function only removes HTML attributes. The display is not a HTML attribute, it's a CSS property. You'd like to use css() function instead to manage CSS properties.

But jQuery offers a show() function which does exactly what you want in a concise call:

$("span").show();

You can do so starting with Postgres 9.1:

with rows as (
INSERT INTO Table1 (name) VALUES ('a_title') RETURNING id
)
INSERT INTO Table2 (val)
SELECT id
FROM rows

In the meanwhile, if you're only interested in the id, you can do so with a trigger:

create function t1_ins_into_t2()
  returns trigger
as $$
begin
  insert into table2 (val) values (new.id);
  return new;
end;
$$ language plpgsql;

create trigger t1_ins_into_t2
  after insert on table1
for each row
execute procedure t1_ins_into_t2();

Check the column collation. This script might change the collation to the table default. Add the current collation to the script.

As of Powershell v3, PSsessions allow for any native cmdlet to be run on a remote machine

$session = New-PSsession -Computername "YourServerName"
Invoke-Command -Session $Session -ScriptBlock {Restart-Service "YourServiceName"}
Remove-PSSession $Session

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761
16 : 18055.955520
15 : 36111.911040
14 : 72223.822090

//lat=3434&lon=yy38&rd=1.0&| in that format o/p is displaying

public class ReadText {
    public static void main(String[] args) throws Exception {
        FileInputStream f= new FileInputStream("D:/workplace/sample/bookstore.txt");
        BufferedReader br = new BufferedReader(new InputStreamReader(f));
        String strline;
        StringBuffer sb = new StringBuffer();
        while ((strline = br.readLine()) != null)
        {
            String[] arraylist=StringUtils.split(strline, ",");
            if(arraylist.length == 2){
                sb.append("lat=").append(StringUtils.trim(arraylist[0])).append("&lon=").append(StringUtils.trim(arraylist[1])).append("&rt=1.0&|");

            } else {
                System.out.println("Error: "+strline);
            }
        }
        System.out.println("Data: "+sb.toString());
    }
}

For a very fast and simple solution where you check equality against a single value, you can use the mask method.

df.mask(df == ' ')

myLabel.setHorizontalAlignment(SwingConstants.CENTER);
myLabel.setVerticalAlignment(SwingConstants.CENTER);

If you cannot reconstruct the label for some reason, this is how you edit these properties of a pre-existent JLabel.

For me simply run:

npm install cross-env

was enough

Works for dynamic controls too.

Javascript

<input type="file" onchange="FileValidate(this)" />

function FileValidate(object) {
    if ((object.files[0].size / 1024 / 1024) > 1) {   //greater than 1 MB         
        $(object).val('');
    }     
}

JQuery

<input type="file" class="UpoloadFileSize">

$(document).ready(function () {

    $('.UpoloadFileSize').bind('change', function () {                
        if ((this.files[0].size / 1024000) > 1.5) { //greater than 1.5 MB
            $(this).val('');
            alert('Size exceeded !!');
        }
    });

});

You have 2 options to change the separator style of a uitableview if you want to change the default options which are no separators, solid line or etched line.

1. The easiest consist in including a separator line background image to each cell view. You may check then where is located your cell in the tableview to apply the right background image that will give you either a separator line on top of the cell or at the bottom of the cell.

   Set the separator style to none in the viewDidLoad of your tableview:

   [self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];

   Set your background image in the (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath function

    UIImage* yourBgImg = [[UIImage imageNamed:@"bgImage.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(5, 5, 5, 5)];
   

   cell.backgroundView = [[UIImageView alloc] initWithImage:yourBgImg];

   check the position of your cell in the section with the following:

   NSInteger sectionRows = [tableView numberOfRowsInSection:[indexPathsection]]; NSInteger row = [indexPath row];

2. Add the separator line as a cell. I find a post recently for this here: http://www.dimzzy.com/blog/2012/01/separator-cells-for-uitableview/#disqus_thread

select a.id, a.object
from table_A a
inner join table_B b on a.id=b.id
where b.tag = 'chair';

If you want a specific order, then you must use an array, not an object. Objects do not have a defined order.

For example, using an array, you could do this:

var myobj = [{"A":["B"]}, {"B": ["C"]}];
var firstItem = myobj[0];

Then, you can use myobj[0] to get the first object in the array.

Or, depending upon what you're trying to do:

var myobj = [{key: "A", val:["B"]}, {key: "B",  val:["C"]}];
var firstKey = myobj[0].key;   // "A"
var firstValue = myobj[0].val; // "["B"]

From the documentation of the HttpWebRequest.Timeout property:

A Domain Name System (DNS) query may take up to 15 seconds to return or time out. If your request contains a host name that requires resolution and you set Timeout to a value less than 15 seconds, it may take 15 seconds or more before a WebException is thrown to indicate a timeout on your request.

Is it possible that your DNS query is the cause of the timeout?

For versions of data.table >= 1.9.8, the following all just work:

library(data.table)
dt <- data.table(a = 1, b = 2, c = 3)

# select single column by index
dt[, 2]
#    b
# 1: 2

# select multiple columns by index
dt[, 2:3]
#    b c
# 1: 2 3

# select single column by name
dt[, "a"]
#    a
# 1: 1

# select multiple columns by name
dt[, c("a", "b")]
#    a b
# 1: 1 2

For versions of data.table < 1.9.8 (for which numerical column selection required the use of with = FALSE), see this previous version of this answer. See also NEWS on v1.9.8, POTENTIALLY BREAKING CHANGES, point 3.

This will vary depending on your architecture and how it treats basic data types. It will also depend on whether the system requires natural alignment.

The Mach-O object file format used by Mac OS X for executables and libraries distinguishes between shared libraries and dynamically loaded modules. Use otool -hv some_file to see the filetype of some_file.

Mach-O shared libraries have the file type MH_DYLIB and carry the extension .dylib. They can be linked against with the usual static linker flags, e.g. -lfoo for libfoo.dylib. They can be created by passing the -dynamiclib flag to the compiler. (-fPIC is the default and needn't be specified.)

Loadable modules are called "bundles" in Mach-O speak. They have the file type MH_BUNDLE. They can carry any extension; the extension .bundle is recommended by Apple, but most ported software uses .so for the sake of compatibility. Typically, you'll use bundles for plug-ins that extend an application; in such situations, the bundle will link against the application binary to gain access to the application’s exported API. They can be created by passing the -bundle flag to the compiler.

Both dylibs and bundles can be dynamically loaded using the dl APIs (e.g. dlopen, dlclose). It is not possible to link against bundles as if they were shared libraries. However, it is possible that a bundle is linked against real shared libraries; those will be loaded automatically when the bundle is loaded.

Historically, the differences were more significant. In Mac OS X 10.0, there was no way to dynamically load libraries. A set of dyld APIs (e.g. NSCreateObjectFileImageFromFile, NSLinkModule) were introduced with 10.1 to load and unload bundles, but they didn't work for dylibs. A dlopen compatibility library that worked with bundles was added in 10.3; in 10.4, dlopen was rewritten to be a native part of dyld and added support for loading (but not unloading) dylibs. Finally, 10.5 added support for using dlclose with dylibs and deprecated the dyld APIs.

On ELF systems like Linux, both use the same file format; any piece of shared code can be used as a library and for dynamic loading.

Finally, be aware that in Mac OS X, "bundle" can also refer to directories with a standardized structure that holds executable code and the resources used by that code. There is some conceptual overlap (particularly with "loadable bundles" like plugins, which generally contain executable code in the form of a Mach-O bundle), but they shouldn't be confused with Mach-O bundles discussed above.

For fpdf to work properly, there cannot be any output at all beside what fpdf generates. For example, this will work:

<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

While this will not (note the leading space before the opening <? tag)

 <?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

Also, this will not work either (the echo will break it):

<?php
echo "About to create pdf";
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

I'm not sure about the drupal side of things, but I know that absolutely zero non-fpdf output is a requirement for fpdf to work.

give me an error as below:
FPDF error: Some data has already been output, can't send PDF

to over come this error: go to fpdf.php in that,goto line number 996

function Output($name='', $dest='')

after that make changes like this:

function Output($name='', $dest='') {   
    ob_clean();     //Output PDF to so

Hi do you have a session header on the top of your page. or any includes If you have then try to add this codes on top pf your page it should works fine.

<?

while (ob_get_level())
ob_end_clean();
header("Content-Encoding: None", true);

?>

cheers :-)

In my case i had set:

ini_set('display_errors', 'on');
error_reporting(E_ALL | E_STRICT);

When i made the request to generate the report, some warnings were displayed in the browser (like the usage of deprecated functions).
Turning off the display_errors option, the report was generated successfully.

you can try this.Add the parameter as output direction and after executing the query get the output parameter value.

  SqlParameter parmOUT = new SqlParameter("@return", SqlDbType.Int);
  parmOUT.Direction = ParameterDirection.Output;
  cmd.Parameters.Add(parmOUT);
  cmd.ExecuteNonQuery();
  int returnVALUE = (int)cmd.Parameters["@return"].Value;

As far as i understand fr is the object of your FileReadExample class. So it is obvious it will not have any method like fr.readLine() if you dont create one yourself.

secondly, i think a correct constructor of the BufferedReader class will help you do your task.

String str;
BufferedReader buffread = new BufferedReader(new FileReader(new File("file.dat")));
str = buffread.readLine();
.
.
buffread.close();

this should help you.

I think you are putting one too many curly brackets. Try this

 @if($user->status=='waiting')
            <td><a href="#" class="viewPopLink btn btn-default1" role="button" data-id="{!! $user->travel_id !!}" data-toggle="modal" data-target="#myModal">Approve/Reject</a> </td>
            @else
            <td>{!! $user->status !!}</td>
        @endif

In case you would like to find the area between 2 values of x mean = 1; standard deviation = 2; the probability of x between [0.5,2]

import scipy.stats
scipy.stats.norm(1, 2).cdf(2) - scipy.stats.norm(1,2).cdf(0.5)

I am almost always dealing with multiple threads and main thread is generally not doing much, so what is most interesting is to dump all the stacks (which is more like the Java's dump). Here is an implementation based on this blog:

import threading, sys, traceback

def dumpstacks(signal, frame):
    id2name = dict([(th.ident, th.name) for th in threading.enumerate()])
    code = []
    for threadId, stack in sys._current_frames().items():
        code.append("\n# Thread: %s(%d)" % (id2name.get(threadId,""), threadId))
        for filename, lineno, name, line in traceback.extract_stack(stack):
            code.append('File: "%s", line %d, in %s' % (filename, lineno, name))
            if line:
                code.append("  %s" % (line.strip()))
    print "\n".join(code)

import signal
signal.signal(signal.SIGQUIT, dumpstacks)

preg_replace("[^\w\s\d\.\-_~,;:\[\]\(\]]", '', $file)

Add/remove more valid characters depending on what is allowed for your system.

Alternatively you can try to create the file and then return an error if it's bad.

In my experience storing all the settings in a database table is the best solution. Don't even worry about performance. Today's databases are fast and can easily store thousands columns in a table. I learned this the hard way - before I was serilizing/deserializing - nightmare. Storing it in local file or registry has one big problem - if you have to support your app and computer is off - user is not in front of it - there is nothing you can do.... if setings are in DB - you can changed them and viola not to mention that you can compare the settings....

The reason this question still often arises is because, as you mentioned, somewhere somehow someone presumed as important wrote that the RFC states domain names without subdomain in front of them are not valid. If you read the RFC carefully, however, you'll find that this is not exactly what it says. In fact, RFC 1912 states:

Don't go overboard with CNAMEs. Use them when renaming hosts, but plan to get rid of them (and inform your users).

Some DNS hosts provide a way to get CNAME-like functionality at the zone apex (the root domain level, for the naked domain name) using a custom record type. Such records include, for example:

• ALIAS at DNSimple
• ANAME at DNS Made Easy
• ANAME at easyDNS
• CNAME at CloudFlare

For each provider, the setup is similar: point the ALIAS or ANAME entry for your apex domain to example.domain.com, just as you would with a CNAME record. Depending on the DNS provider, an empty or @ Name value identifies the zone apex.

ALIAS or ANAME or @ example.domain.com.

If your DNS provider does not support such a record-type, and you are unable to switch to one that does, you will need to use subdomain redirection, which is not that hard, depending on the protocol or server software that needs to do it.

I strongly disagree with the statement that it's done only by "amateur admins" or such ideas. It's a simple "What does the name and its service need to do?" deal, and then to adapt your DNS config to serve those wishes; If your main services are web and e-mail, I don' t see any VALID reason why dropping the CNAMEs for-good would be problematic. After all, who would prefer @subdomain.domain.org over @domain.org ? Who needs "www" if you're already set with the protocol itself? It's illogical to assume that use of a root-domainname would be invalid.

Select your proper configuration for launching Application.

Between matplotlib+pylab and NumPy I don't think there's much actual difference between Matlab and python other than cultural inertia as suggested by @Adam Bellaire.

In Swift 4.1 and Xcode 10

You can scale up the fonts in your call to sns.set().

import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
x = np.random.normal(size=37)
y = np.random.lognormal(size=37)

# defaults
sns.set()
fig, ax = plt.subplots()
ax.plot(x, y, marker='s', linestyle='none', label='small')
ax.legend(loc='upper left', bbox_to_anchor=(0, 1.1))

sns.set(font_scale=5)  # crazy big
fig, ax = plt.subplots()
ax.plot(x, y, marker='s', linestyle='none', label='big')
ax.legend(loc='upper left', bbox_to_anchor=(0, 1.3))

![In Xcode 8 & above go to build setting -> search for custom flags ]1

In code

 #if Live
    print("Live")
    #else
    print("debug")
    #endif

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

You can't declare an extern local method inside of a method, or any other method with an attribute. Move your DLL import into the class:

using System.Runtime.InteropServices;


public class WindowHandling
{
    [DllImport("User32.dll")]
    public static extern int SetForegroundWindow(IntPtr point);

    public void ActivateTargetApplication(string processName, List<string> barcodesList)
    {
        Process p = Process.Start("notepad++.exe");
        p.WaitForInputIdle();
        IntPtr h = p.MainWindowHandle;
        SetForegroundWindow(h);
        SendKeys.SendWait("k");
        IntPtr processFoundWindow = p.MainWindowHandle;
    }
}

Old way:

SELECT DATE_COLUMN + 1 is adding a day
SELECT DATE_COLUMN + N /24 to add hour(s) - N being number of hours
SELECT DATE_COLUMN + N /1440 to add minute(s) - N being number of minutes
SELECT DATE_COLUMN + N /86400 to add second(s) - N being number of seconds

Using INTERVAL:

SELECT DATE_COLUMN + INTERVAL 'N' HOUR or MINUTE or SECOND - N being a number of hours or minutes or seconds.

I came across this forum thread while trying to identify a regex for the following English statement:

Given an input string, match everything unless this input string is exactly 'bar'; for example I want to match 'barrier' and 'disbar' as well as 'foo'.

Here's the regex I came up with

^(bar.+|(?!bar).*)$

My English translation of the regex is "match the string if it starts with 'bar' and it has at least one other character, or if the string does not start with 'bar'.

Try this: edited

Here's a list of the environment variables. I think you might want CURRENT_VARIANT. See also BUILD_VARIANTS.

After visiting this question and noting the initial concerns of the chosen solution, I figured I'd contribute this one for those not using Java 7 which uses FileUtils instead of IOUtils from Apache Commons. The advantage here is that the readFileToString and the writeStringToFile handle the issue of closing the files for you automatically. (writeStringToFile doesn't document it but you can read the source). Hopefully this recipe simplifies things for anyone new coming to this problem.

  try {
     String content = FileUtils.readFileToString(new File("InputFile"), "UTF-8");
     content = content.replaceAll("toReplace", "replacementString");
     File tempFile = new File("OutputFile");
     FileUtils.writeStringToFile(tempFile, content, "UTF-8");
  } catch (IOException e) {
     //Simple exception handling, replace with what's necessary for your use case!
     throw new RuntimeException("Generating file failed", e);
  }

Why do people always use jQuery when it isn't necessary?
Why can't people just use simple JavaScript?

var ele = /*Your Form Element*/;
if(ele.addEventListener){
    ele.addEventListener("submit", callback, false);  //Modern browsers
}else if(ele.attachEvent){
    ele.attachEvent('onsubmit', callback);            //Old IE
}

callback is a function that you want to call when the form is being submitted.

About EventTarget.addEventListener, check out this documentation on MDN.

To cancel the native submit event (prevent the form from being submitted), use .preventDefault() in your callback function,

document.querySelector("#myForm").addEventListener("submit", function(e){
    if(!isValid){
        e.preventDefault();    //stop form from submitting
    }
});

Listening to the submit event with libraries

If for some reason that you've decided a library is necessary (you're already using one or you don't want to deal with cross-browser issues), here's a list of ways to listen to the submit event in common libraries:

1. jQuery

   $(ele).submit(callback);
   

   Where ele is the form element reference, and callback being the callback function reference. Reference

    <iframe width="100%" height="100%" src="http://jsfiddle.net/DerekL/wnbo1hq0/show" frameborder="0"></iframe>

2. AngularJS (1.x)

   <form ng-submit="callback()">
   
   $scope.callback = function(){ /*...*/ };
   

   Very straightforward, where $scope is the scope provided by the framework inside your controller. Reference

3. React

   <form onSubmit={this.handleSubmit}>
   
   class YourComponent extends Component {
       // stuff
   
       handleSubmit(event) {
           // do whatever you need here
   
           // if you need to stop the submit event and 
           // perform/dispatch your own actions
           event.preventDefault();
       }
   
       // more stuff
   }
   

   Simply pass in a handler to the onSubmit prop. Reference

4. Other frameworks/libraries

   Refer to the documentation of your framework.

Validation

You can always do your validation in JavaScript, but with HTML5 we also have native validation.

<!-- Must be a 5 digit number -->
<input type="number" required pattern="\d{5}">

You don't even need any JavaScript! Whenever native validation is not supported, you can fallback to a JavaScript validator.

Demo: http://jsfiddle.net/DerekL/L23wmo1L/

You have correctly used "CURLOPT_COOKIEJAR" (writing) but you also need to set "CURLOPT_COOKIEFILE" (reading)

curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE); 
curl_setopt ($ch, CURLOPT_COOKIEFILE, COOKIE_FILE); 

So the key parts are to grab the header ( col_names = s.row(0) ) and when iterating through the rows, to skip the first row which isn't needed for row in range(1, s.nrows) - done by using range from 1 onwards (not the implicit 0). You then use zip to step through the rows holding 'name' as the header of the column.

from xlrd import open_workbook

wb = open_workbook('Book2.xls')
values = []
for s in wb.sheets():
    #print 'Sheet:',s.name
    for row in range(1, s.nrows):
        col_names = s.row(0)
        col_value = []
        for name, col in zip(col_names, range(s.ncols)):
            value  = (s.cell(row,col).value)
            try : value = str(int(value))
            except : pass
            col_value.append((name.value, value))
        values.append(col_value)
print values

asyncio.wait is more low level than asyncio.gather.

As the name suggests, asyncio.gather mainly focuses on gathering the results. It waits on a bunch of futures and returns their results in a given order.

asyncio.wait just waits on the futures. And instead of giving you the results directly, it gives done and pending tasks. You have to manually collect the values.

Moreover, you could specify to wait for all futures to finish or just the first one with wait.

Run aspnet_regiis -i. Often I've found you need to do that to get 4.0 apps to work. Open a command prompt as an Administrator (right click the command prompt icon and select Run as Administrator):

cd \
cd Windows\Microsoft.NET\Framework\v4.xxx.xxx
aspnet_regiis -i

Once it has installed and registered, make sure you application is using an application pool that is set to .NET 4.0.

UPDATE: I just found an issue with this command. Using -i updated all application pools to ASP.NET 4.0.

Using aspnet_regiis -ir installs the version of ASP.NET but does not change any web applications to this version. You may also want to review the -iru option.

The function :getargc below may be what you're looking for.

@echo off
setlocal enableextensions enabledelayedexpansion
call :getargc argc %*
echo Count is %argc%
echo Args are %*
endlocal
goto :eof

:getargc
    set getargc_v0=%1
    set /a "%getargc_v0% = 0"
:getargc_l0
    if not x%2x==xx (
        shift
        set /a "%getargc_v0% = %getargc_v0% + 1"
        goto :getargc_l0
    )
    set getargc_v0=
    goto :eof

It basically iterates once over the list (which is local to the function so the shifts won't affect the list back in the main program), counting them until it runs out.

It also uses a nifty trick, passing the name of the return variable to be set by the function.

The main program just illustrates how to call it and echos the arguments afterwards to ensure that they're untouched:

C:\Here> xx.cmd 1 2 3 4 5
    Count is 5
    Args are 1 2 3 4 5
C:\Here> xx.cmd 1 2 3 4 5 6 7 8 9 10 11
    Count is 11
    Args are 1 2 3 4 5 6 7 8 9 10 11
C:\Here> xx.cmd 1
    Count is 1
    Args are 1
C:\Here> xx.cmd
    Count is 0
    Args are
C:\Here> xx.cmd 1 2 "3 4 5"
    Count is 3
    Args are 1 2 "3 4 5"

This should get you started: Using VBA in your own Excel workbook, have it prompt the user for the filename of their data file, then just copy that fixed range into your target workbook (that could be either the same workbook as your macro enabled one, or a third workbook). Here's a quick vba example of how that works:

' Get customer workbook...
Dim customerBook As Workbook
Dim filter As String
Dim caption As String
Dim customerFilename As String
Dim customerWorkbook As Workbook
Dim targetWorkbook As Workbook

' make weak assumption that active workbook is the target
Set targetWorkbook = Application.ActiveWorkbook

' get the customer workbook
filter = "Text files (*.xlsx),*.xlsx"
caption = "Please Select an input file "
customerFilename = Application.GetOpenFilename(filter, , caption)

Set customerWorkbook = Application.Workbooks.Open(customerFilename)

' assume range is A1 - C10 in sheet1
' copy data from customer to target workbook
Dim targetSheet As Worksheet
Set targetSheet = targetWorkbook.Worksheets(1)
Dim sourceSheet As Worksheet
Set sourceSheet = customerWorkbook.Worksheets(1)

targetSheet.Range("A1", "C10").Value = sourceSheet.Range("A1", "C10").Value

' Close customer workbook
customerWorkbook.Close

Why and when you should mark the request parameter as implicit:

Some methods that you will make use of in the body of your action have an implicit parameter list like, for example, Form.scala defines a method:

def bindFromRequest()(implicit request: play.api.mvc.Request[_]): Form[T] = { ... }

You don't necessarily notice this as you would just call myForm.bindFromRequest() You don't have to provide the implicit arguments explicitly. No, you leave the compiler to look for any valid candidate object to pass in every time it comes across a method call that requires an instance of the request. Since you do have a request available, all you need to do is to mark it as implicit.

You explicitly mark it as available for implicit use.

You hint the compiler that it's "OK" to use the request object sent in by the Play framework (that we gave the name "request" but could have used just "r" or "req") wherever required, "on the sly".

myForm.bindFromRequest()

see it? it's not there, but it is there!

It just happens without your having to slot it in manually in every place it's needed (but you can pass it explicitly, if you so wish, no matter if it's marked implicit or not):

myForm.bindFromRequest()(request)

Without marking it as implicit, you would have to do the above. Marking it as implicit you don't have to.

When should you mark the request as implicit? You only really need to if you are making use of methods that declare an implicit parameter list expecting an instance of the Request. But to keep it simple, you could just get into the habit of marking the request implicit always. That way you can just write beautiful terse code.

I wanted to be able to access my application with the HTML5 mode and a fixed token and then switch to the hashbang method (to keep the token so the user can refresh his page).

URL for accessing my app:

http://myapp.com/amazing_url?token=super_token

Then when the user loads the page:

http://myapp.com/amazing_url?token=super_token#/amazing_url

Then when the user navigates:

http://myapp.com/amazing_url?token=super_token#/another_url

With this I keep the token in the URL and keep the state when the user is browsing. I lost a bit of visibility of the URL, but there is no perfect way of doing it.

So don't enable the HTML5 mode and then add this controller:

.config ($stateProvider)->
    $stateProvider.state('home-loading', {
         url: '/',
         controller: 'homeController'
    })
.controller 'homeController', ($state, $location)->
    if window.location.pathname != '/'
        $location.url(window.location.pathname+window.location.search).replace()
    else
        $state.go('home', {}, { location: 'replace' })

private string GetExtension(string attachment_name)

    var index_point = attachment_name.IndexOf(".") + 1;
    return attachment_name.Substring(index_point);

Update manually from mysql website

Here's a solution for Ubuntu 15.04 users running Mysql Workbench 6.2.3.

I was able to resolve the issue of missing results in the Mysql workbench by just upgrading mysql-workbench to version 6.3.3 from http://dev.mysql.com/downloads/workbench/. You will need to download the one marked for Ubuntu 14.10. An install via Ubuntu software center resolved the issue. Hope this helps.

Here's what's usually sufficient for me:

I create a serialization mixin which I use with my models. The serialization function basically fetches whatever attributes the SQLAlchemy inspector exposes and puts it in a dict.

from sqlalchemy.inspection import inspect

class Serializer(object):

    def serialize(self):
        return {c: getattr(self, c) for c in inspect(self).attrs.keys()}

    @staticmethod
    def serialize_list(l):
        return [m.serialize() for m in l]

All that's needed now is to extend the SQLAlchemy model with the Serializer mixin class.

If there are fields you do not wish to expose, or that need special formatting, simply override the serialize() function in the model subclass.

class User(db.Model, Serializer):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String)
    password = db.Column(db.String)

    # ...

    def serialize(self):
        d = Serializer.serialize(self)
        del d['password']
        return d

In your controllers, all you have to do is to call the serialize() function (or serialize_list(l) if the query results in a list) on the results:

def get_user(id):
    user = User.query.get(id)
    return json.dumps(user.serialize())

def get_users():
    users = User.query.all()
    return json.dumps(User.serialize_list(users))

Maybe you can try this:

int function(){
Scanner input = new Scanner(System.in);   
System.out.print("Enter an integer between 1-100: ");   
int range;
while(true){   
    if(input.hasNextInt()){   
    range = input.nextInt();
    if(0<=range && range <= 100)
        break;
    else
        continue;
    }
    input.nextLine();  //Comsume the garbage value
    System.out.println("Enter an integer between 1-100:");
}
return range;
}

Or you can create a form with action:mailto

<form action="mailto:[email protected]"> 

check this out.

http://webdesign.about.com/od/forms/a/aa072699mailto.htm

But this actually submits a form via email.Is this what you wanted? You can also use just

<button onclick=""> and then some javascript with it to ahieve this.

And you can make a <a> look like button. There can be a lot of ways to work this around. Do a little search.

lvalue means "left value" -- it should be assignable. You cannot change the value of text since it is an array, not a pointer.

Either declare it as char pointer (in this case it's better to declare it as const char*):

const char *text;
if(number == 2) 
    text = "awesome"; 
else 
    text = "you fail";

Or use strcpy:

char text[60];
if(number == 2) 
    strcpy(text, "awesome"); 
else 
    strcpy(text, "you fail");

i guess you mean System Programs and Application programs

System Programs makes the hardware run , Applications are for specific tasks

an Example for System Programs are Device Drivers

as for the Applications you can say web browsers , word porcessros etc

Strangely enough,

package main

func main () {
    var sessions = map[string] chan int{};
    delete(sessions, "moo");
}

seems to work. This seems a poor use of resources though!

Another way is to check for existence and use the value itself:

package main

func main () {
    var sessions = map[string] chan int{};
    sessions["moo"] = make (chan int);
    _, ok := sessions["moo"];
    if ok {
        delete(sessions, "moo");
    }
}

Here is what I ultimately had to do to figure out what "other query" caused the lock timeout problem. In the application code, we track all pending database calls on a separate thread dedicated to this task. If any DB call takes longer than N-seconds (for us it's 30 seconds) we log:

-- Pending InnoDB transactions
SELECT * FROM information_schema.innodb_trx ORDER BY trx_started; 

-- Optionally, log what transaction holds what locks
SELECT * FROM information_schema.innodb_locks;

With above, we were able to pinpoint concurrent queries that locked the rows causing the deadlock. In my case, they were statements like INSERT ... SELECT which unlike plain SELECTs lock the underlying rows. You can then reorganize the code or use a different transaction isolation like read uncommitted.

Good luck!
