As Tuomas said, your header should be minimal. To be complete I will expand a bit.

I personally use 4 types of files in my C++ projects:

• Public:
• Forwarding header: in case of templates etc, this file get the forwarding declarations that will appear in the header.
• Header: this file includes the forwarding header, if any, and declare everything that I wish to be public (and defines the classes...)
• Private:
• Private header: this file is a header reserved for implementation, it includes the header and declares the helper functions / structures (for Pimpl for example or predicates). Skip if unnecessary.
• Source file: it includes the private header (or header if no private header) and defines everything (non-template...)

Furthermore, I couple this with another rule: Do not define what you can forward declare. Though of course I am reasonable there (using Pimpl everywhere is quite a hassle).

It means that I prefer a forward declaration over an #include directive in my headers whenever I can get away with them.

Finally, I also use a visibility rule: I limit the scopes of my symbols as much as possible so that they do not pollute the outer scopes.

Putting it altogether:

// example_fwd.hpp
// Here necessary to forward declare the template class,
// you don't want people to declare them in case you wish to add
// another template symbol (with a default) later on
class MyClass;
template <class T> class MyClassT;

// example.hpp
#include "project/example_fwd.hpp"

// Those can't really be skipped
#include <string>
#include <vector>

#include "project/pimpl.hpp"

// Those can be forward declared easily
#include "project/foo_fwd.hpp"

namespace project { class Bar; }

namespace project
{
  class MyClass
  {
  public:
    struct Color // Limiting scope of enum
    {
      enum type { Red, Orange, Green };
    };
    typedef Color::type Color_t;

  public:
    MyClass(); // because of pimpl, I need to define the constructor

  private:
    struct Impl;
    pimpl<Impl> mImpl; // I won't describe pimpl here :p
  };

  template <class T> class MyClassT: public MyClass {};
} // namespace project

// example_impl.hpp (not visible to clients)
#include "project/example.hpp"
#include "project/bar.hpp"

template <class T> void check(MyClass<T> const& c) { }

// example.cpp
#include "example_impl.hpp"

// MyClass definition

The lifesaver here is that most of the times the forward header is useless: only necessary in case of typedef or template and so is the implementation header ;)

Well, char (or its wrapper class Character) means a single character, i.e. you can't write 'ab' whereas String is a text consisting of a number of characters and you can think of a string a an array of characters (in fact the String class has a member char[] value).

You could work with plain char arrays but that's quite tedious and thus the String class is there to provide a convenient way for working with texts.

I had a similar problem. I wanted to have pretty URLs and reached the conclusion that I have to allow only letters, digits, - and _ in URLs.

That is fine, but then I wrote some nice regex and I realized that it recognizes all UTF-8 characters are not letters in .NET and was screwed. This appears to be a know problem for the .NET regex engine. So I got to this solution:

private static string GetTitleForUrlDisplay(string title)
{
    if (!string.IsNullOrEmpty(title))
    {
        return Regex.Replace(Regex.Replace(title, @"[^A-Za-z0-9_-]", new MatchEvaluator(CharacterTester)).Replace(' ', '-').TrimStart('-').TrimEnd('-'), "[-]+", "-").ToLower();
    }
    return string.Empty;
}


/// <summary>
/// All characters that do not match the patter, will get to this method, i.e. useful for Unicode characters, because
/// .NET implementation of regex do not handle Unicode characters. So we use char.IsLetterOrDigit() which works nicely and we
/// return what we approve and return - for everything else.
/// </summary>
/// <param name="m"></param>
/// <returns></returns>
private static string CharacterTester(Match m)
{
    string x = m.ToString();
    if (x.Length > 0 && char.IsLetterOrDigit(x[0]))
    {
        return x.ToLower();
    }
    else
    {
        return "-";
    }
}

select GROUP_CONCAT(stat SEPARATOR ' ') from (select concat('KILL ',id,';') as stat from information_schema.processlist) as stats;

Then copy and paste the result back into the terminal. Something like:

KILL 2871; KILL 2879; KILL 2874; KILL 2872; KILL 2866;

time.second helps a lot put that at the top of your python.

If it helps...

I use the PHP function number_format() and the Narrow No-break Space ( ). It is often used as an unambiguous thousands separator.

echo number_format(200000, 0, "", " ");

Because IE8 has some problems to render the Narrow No-break Space, I changed it for a SPAN

echo "<span class='number'>".number_format(200000, 0, "", "<span></span>")."</span>";

.number SPAN{
    padding: 0 1px; 
}

Here is a bit more robust way of doing this, also handling the return values of enable()\disable() methods:

public static boolean setBluetooth(boolean enable) {
    BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
    boolean isEnabled = bluetoothAdapter.isEnabled();
    if (enable && !isEnabled) {
        return bluetoothAdapter.enable(); 
    }
    else if(!enable && isEnabled) {
        return bluetoothAdapter.disable();
    }
    // No need to change bluetooth state
    return true;
}

And add the following permissions into your manifest file:

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

But remember these important points:

This is an asynchronous call: it will return immediately, and clients should listen for ACTION_STATE_CHANGED to be notified of subsequent adapter state changes. If this call returns true, then the adapter state will immediately transition from STATE_OFF to STATE_TURNING_ON, and some time later transition to either STATE_OFF or STATE_ON. If this call returns false then there was an immediate problem that will prevent the adapter from being turned on - such as Airplane mode, or the adapter is already turned on.

UPDATE:

Ok, so how to implement bluetooth listener?:

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        final String action = intent.getAction();

        if (action.equals(BluetoothAdapter.ACTION_STATE_CHANGED)) {
            final int state = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE,
                                                 BluetoothAdapter.ERROR);
            switch (state) {
            case BluetoothAdapter.STATE_OFF:
                // Bluetooth has been turned off;
                break;
            case BluetoothAdapter.STATE_TURNING_OFF:
                // Bluetooth is turning off;
                break;
            case BluetoothAdapter.STATE_ON:
                // Bluetooth is on
                break;
            case BluetoothAdapter.STATE_TURNING_ON:
                // Bluetooth is turning on
                break;
            }
        }
    }
};

And how to register/unregister the receiver? (In your Activity class)

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // ...

    // Register for broadcasts on BluetoothAdapter state change
    IntentFilter filter = new IntentFilter(BluetoothAdapter.ACTION_STATE_CHANGED);
    registerReceiver(mReceiver, filter);
}

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

     // ...

    // Unregister broadcast listeners
    unregisterReceiver(mReceiver);
}

To solve the problem of:

E: Unable to locate package python-pip

you should do this. This works with the python2.7 and you not going to get disappointed by it. follow the steps that are mention below. go to get-pip.py and copy all the code from it.
open the terminal using CTRL + ALT +T

vi get-pip.py

paste the copied code here and then exit from the vi editor by pressing

ESC then :wq => press Enter

lastly, now run the code and see the magic

sudo python get-pip.py

It automatically adds the pip command in your Linux.
you can see the output of my machine

It seems that GSon don't support JAXB. By using JAXB annotated class to create or process the JSON message, I can share the same class to create the Restful Web Service interface by using spring MVC.

Here you go:

USE information_schema;
SELECT *
FROM
  KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_NAME = 'X'
  AND REFERENCED_COLUMN_NAME = 'X_id';

If you have multiple databases with similar tables/column names you may also wish to limit your query to a particular database:

SELECT *
FROM
  KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_NAME = 'X'
  AND REFERENCED_COLUMN_NAME = 'X_id'
  AND TABLE_SCHEMA = 'your_database_name';

@Pascal's comment on the OP's question is right. By simply adding the image, it removes the black borders and the app will use the full height.

You will need to make adjustments to any CGRects by determining that the device is using the bigger display. I.e. If you need something aligned to the bottom of the screen.

I am sure there is a built in method, but I haven't seen anything and a lot is still under NDA so the method we use in our apps is quite simply a global function. Add the following to your .pch file and then its a simple if( is4InchRetina() ) { ... } call to make adjustments to your CGRects etc.

static BOOL is4InchRetina()
{
    if (![UIApplication sharedApplication].statusBarHidden && (int)[[UIScreen mainScreen] applicationFrame].size.height == 548 || [UIApplication sharedApplication].statusBarHidden && (int)[[UIScreen mainScreen] applicationFrame].size.height == 568)
        return YES;

    return NO;
}

If you have import android.support.v7.app.ActionBarActivity; and your class extends ActionBarActivity then use this in your OnCreate:

android.support.v7.app.ActionBar AB=getSupportActionBar();
AB.hide();

I think there is no out-of-the-box support for that in VS Code.

You can install a plugin to give you similar functionality. Eg.:

https://marketplace.visualstudio.com/items?itemName=micnil.vscode-checkpoints

Or the more famous:

https://marketplace.visualstudio.com/items?itemName=xyz.local-history

Some details may need to be configured: The VS Code search gets confused sometimes because of additional folders created by this type of plugins. You can configure it to ignore such folders or change their locations (adding such folders to your .gitignore file also solves this problem).

    String u = request.getParameter("username");
    String p = request.getParameter("password");

    try {
        st = con.createStatement();
        String sql;
        sql = "SELECT * FROM TableName where USERNAME = '" + u + "' and PASSWORD = '"
                + p + "'";
        ResultSet rs = st.executeQuery(sql);
        if (rs.next()) {
            RequestDispatcher requestDispatcher = request
                    .getRequestDispatcher("/home.jsp");
            requestDispatcher.forward(request, response);
        } else {

            RequestDispatcher requestDispatcher = request
                    .getRequestDispatcher("/invalidLogin.jsp");
            requestDispatcher.forward(request, response);

        }

    } catch (Exception e) {
        e.printStackTrace();
    }
    finally{
        try {
            rs.close();
            ps.close();
            con.close();
            st.close();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

Try or:

WHERE id = 3 or id = 4

Or the equivalent in:

WHERE id in (3,4)

If you have desired permissions saved to string then do

s = '660'
os.chmod(file_path, int(s, base=8))

just use file_put_contents('file',$myarray); file_put_contents() works with arrays too.

I use this way to get it:

const queryParamsObj = {foo: 1, bar: 2, andThis: 'text'};

this.location.replaceState(
  this.router.createUrlTree(
    [this.locationStrategy.path().split('?')[0]], // Get uri
    {queryParams: queryParamsObj} // Pass all parameters inside queryParamsObj
  ).toString()
);

-- EDIT --

I think that I should add some more informations for this.

If you use this.location.replaceState() router of your application is not updated, so if you use router information later it's not equal for this in your browser. For example if you use localizeService to change language, after switch language your application back to last URL where you was before change it with this.location.replaceState().

If you don't want this behaviour you can chose different method for update URL, like:

this.router.navigate(
  [this.locationStrategy.path().split('?')[0]],
  {queryParams: queryParamsObj}
);

In this option your browser also doesn't refresh but your URL change is also injected into Router of your application, so when you switch language you don't have problem like in this.location.replaceState().

Of course you can choose method for your needs. The first is more lighter because you don't engage your application more than change URL in browser.

I'll add Android docs link to other answers.

https://developer.android.com/guide/topics/resources/drawable-resource.html#Shape

It describes all attributes of the Shape Drawable and stroke among them to set the border.

Example:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
  <stroke android:width="1dp" android:color="#F00"/>
  <solid android:color="#0000"/>
</shape>

Red border with transparent background.

As much as your available memory will allow. There's no size limit except for the heap.

Bonus Tip

You can't directly register an IUrlHelper in the DI container. Resolving an instance of IUrlHelper requires you to use the IUrlHelperFactory and IActionContextAccessor. However, you can do the following as a shortcut:

services
    .AddSingleton<IActionContextAccessor, ActionContextAccessor>()
    .AddScoped<IUrlHelper>(x => x
        .GetRequiredService<IUrlHelperFactory>()
        .GetUrlHelper(x.GetRequiredService<IActionContextAccessor>().ActionContext));

ASP.NET Core Backlog

UPDATE: This won't make ASP.NET Core 5

There are indications that you will be able to use LinkGenerator to create absolute URL's without the need to provide a HttpContext (This was the biggest downside of LinkGenerator and why IUrlHelper although more complex to setup using the solution below was easier to use) See "Make it easy to configure a host/scheme for absolute URLs with LinkGenerator".

I know this post is old but here is what I found. It doesn't work when I link it this way(with / before css/style.csson the href attribute.

<link rel="stylesheet" media="all" href="/CSS/Style.css" type="text/css" />

However, when I removed / I'm able to link properly with the css file It should be like this(without /).

<link rel="stylesheet" media="all" href="CSS/Style.css" type="text/css" />

This was giving me trouble on my project. Hope it will help somebody else.

To keep this simple, I just changed the directory from which I was importing the data to a local folder on the server.

I had the file located on a shared folder, I just copied my files to "c:\TEMP\Reports" on my server (updated the query to BULK INSERT from the new folder). The Agent task completed successfully :)

Finally after a long time I'm able to BULK Insert automatically via agent job.

You can use SwiftGif from this link

Usage:

imageView.loadGif(name: "jeremy")

A way to solve this without needing to use a FileSystemResource that requires a file on disk, is to use a ByteArrayResource, that way you can send a byte array in your post (this code works with Spring 3.2.3):

MultiValueMap<String, Object> map = new LinkedMultiValueMap<String, Object>();
final String filename="somefile.txt";
map.add("name", filename);
map.add("filename", filename);
ByteArrayResource contentsAsResource = new ByteArrayResource(content.getBytes("UTF-8")){
            @Override
            public String getFilename(){
                return filename;
            }
        };
map.add("file", contentsAsResource);
String result = restTemplate.postForObject(urlForFacade, map, String.class);

I override the getFilename of the ByteArrayResource because if I don't I get a null pointer exception (apparently it depends on whether the java activation .jar is on the classpath, if it is, it will use the file name to try to determine the content type)

Usually i prefer like below in swift 3, because i can add file name and create a file easily

let fileManager = FileManager.default
if let documentsURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first {
    let databasePath = documentsURL.appendingPathComponent("db.sqlite3").path
    print("directory path:", documentsURL.path)
    print("database path:", databasePath)
    if !fileManager.fileExists(atPath: databasePath) {
        fileManager.createFile(atPath: databasePath, contents: nil, attributes: nil)
    }
}

1. Push Ctrl+H
2. Got to File Search tab
3. Enter "// TODO Auto-generated method stub" in Containing Text field
4. Enter "*.java" in Filename patterns field
5. Select proper scope

I am using jquery for datepicker.These jqueries are used for that

<script src="jqueryCalendar/jquery-1.6.2.min.js"></script>
<script src="jqueryCalendar/jquery-ui-1.8.15.custom.min.js"></script>
<link rel="stylesheet" href="jqueryCalendar/jqueryCalendar.css">

Then you follow this code,

<script>
     jQuery(function() {
     jQuery( "#date" ).datepicker({ dateFormat: 'dd/mm/yy' });
                });
</script>

In newer versions of Notepad++ (currently 5.9), this option is under:

View->Show Symbol->Show All Characters

or

View->Show Symbol->Show White Space and Tab

Just return true instead?

The return value from the onClick code is what determines whether the link's inherent clicked action is processed or not - returning false means that it isn't processed, but if you return true then the browser will proceed to process it after your function returns and go to the proper anchor.

UTF-8 does not have a BOM as it is both superfluous and invalid. Where a BOM is helpful is in UTF-16 which may be byte swapped as in the case of Microsoft. UTF-16 if for internal representation in a memory buffer. Use UTF-8 for interchange. By default both UTF-8, anything else derived from US-ASCII and UTF-16 are natural/network byte order. The Microsoft UTF-16 requires a BOM as it is byte swapped.

To covert Windows-1252 to ISO8859-15, I first convert ISO8859-1 to US-ASCII for codes with similar glyphs. I then convert Windows-1252 up to ISO8859-15, other non-ISO8859-15 glyphs to multiple US-ASCII characters.

Map is an interface in Java. And HashMap is an implementation of that interface (i.e. provides all of the methods specified in the interface).

In my case, my problem was environmental. Meaning, I did something wrong in my bash session. After attempting nearly everything in this thread, I opened a new bash session and everything was back to normal.

If it's your root module just add it to PYTHONPATH (PyCharm usually does that)

export PYTHONPATH=$PYTHONPATH:<root module path>

for Docker:

ENV PYTHONPATH="${PYTHONPATH}:<root module path in container>"

Pretty late answer, but hopefully someone will find this useful

I had a situation like this:

1. List item

   a. List item

Where the first item was <strong>, the sub-element was normal weight and the '1.' just wouldn't bold.

My solution was via jQuery:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function () {
        if ($('ol').has('li').has('strong')) {
            $('ol ').css('font-weight', 'bold');
            $('ol > li > ol').css('font-weight', 'normal');
        }
     });
</script>

Hopefully this helps someone!

select A, B, 'c' as C
from MyTable

Use the attr method of jQuery like this:

alert($('input').attr('name'));

Note that you can also use attr to set the attribute values by specifying second argument:

$('input').attr('name', 'new_name')

What is webpack & webpack-dev-server? Official documentation says it's a module bundler but for me it's just a task runner. What's the difference?

webpack-dev-server is a live reloading web server that Webpack developers use to get immediate feedback what they do. It should only be used during development.

This project is heavily inspired by the nof5 unit test tool.

Webpack as the name implies will create a SINGLE package for the web. The package will be minimized, and combined into a single file (we still live in HTTP 1.1 age). Webpack does the magic of combining the resources (JavaScript, CSS, images) and injecting them like this: <script src="assets/bundle.js"></script>.

It can also be called module bundler because it must understand module dependencies, and how to grab the dependencies and to bundle them together.

Where would you use browserify? Can't we do the same with node/ES6 imports?

You could use Browserify on the exact same tasks where you would use Webpack. – Webpack is more compact, though.

Note that the ES6 module loader features in Webpack2 are using System.import, which not a single browser supports natively.

When would you use gulp/grunt over npm + plugins?

You can forget Gulp, Grunt, Brokoli, Brunch and Bower. Directly use npm command line scripts instead and you can eliminate extra packages like these here for Gulp:

var gulp        = require('gulp'),
  minifyCSS     = require('gulp-minify-css'),
  sass          = require('gulp-sass'),
  browserify    = require('gulp-browserify'),
  uglify        = require('gulp-uglify'),
  rename        = require('gulp-rename'),
  jshint        = require('gulp-jshint'),
  jshintStyle   = require('jshint-stylish'),
  replace       = require('gulp-replace'),
  notify        = require('gulp-notify'),

You can probably use Gulp and Grunt config file generators when creating config files for your project. This way you don't need to install Yeoman or similar tools.

In my "Ubuntu 16.04", I use next steps to completely remove and clean Kubernetes (installed with "apt-get"):

kubeadm reset
sudo apt-get purge kubeadm kubectl kubelet kubernetes-cni kube*   
sudo apt-get autoremove  
sudo rm -rf ~/.kube

And restart the computer.

Plain and simple:

plt.plot(x, y, 'r-', alpha=0.7)

(I know I add nothing new, but the straightforward answer should be visible).

setSize will resize the component to the specified size.

setPreferredSize sets the preferred size. The component may not actually be this size depending on the size of the container it's in, or if the user re-sized the component manually.

        $("#tbl_Customer tbody tr .companyname").click(function () {

            var CompanyAddress = $(this).closest(".trclass").find(".CompanyAddress").text();
            var CompanyEmail = $(this).closest(".trclass").find(".CompanyEmail").text();

http://www.linuxquestions.org/questions/linux-newbie-8/forcing-static-linking-of-shared-libraries-696714/

http://linux.derkeiler.com/Newsgroups/comp.os.linux.development.apps/2004-05/0436.html

You need the static version of the library to link it.

A shared library is actually an executable in a special format with entry points specified (and some sticky addressing issues included). It does not have all the information needed to link statically.

You can't statically link a shared library (or dynamically link a static one).

The flag -static will force the linker to use static libraries (.a) instead of shared (.so) ones. But static libraries aren't always installed by default, so you may have to install the static library yourself.

Another possible approach is to use statifier or Ermine. Both tools take as input a dynamically linked executable and as output create a self-contained executable with all shared libraries embedded.

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

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

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

Sample white-list:

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

Sample white-list using a generator-expression:

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

You can use reject method of Underscore, below will return a new array which won't have array with particular match

arr = _.reject(arr, function(objArr){ return objArr.id == 3; });

If you don't want to group your result, use a window function.

You didn't state your DBMS, but this is ANSI SQL:

SELECT AccountNumber, 
       Bill, 
       BillDate, 
       SUM(Bill) over (partition by accountNumber) as account_total
FROM Table1
order by AccountNumber, BillDate;

Here is an SQLFiddle: http://sqlfiddle.com/#!15/2c35e/1

You can even add a running sum, by adding:

sum(bill) over (partition by account_number order by bill_date) as sum_to_date

which will give you the total up to the current's row date.

@classmethod

@classmethod may be compared with __init__. You could think it is another __init__(). It is the way python realize class constructor overloading in c++.

class C:
    def __init__(self, parameters):
        ....

    @classmethod
    def construct_from_func(cls, parameters):
        ....

obj1 = C(parameters)
obj2 = C.construct_from_func(parameters)

notice they both has a reference for class as first argument in definitioin while __init__ use self but construct_from_func use cls conventionally.

@staticmethod

@staticmethod may be compared with object method

class C:
    def __init__(self):
        ....

    @staticmethod
    def static_method(args):
        ....

    def normal_method(parameters):
        ....

result = C.static_method(parameters)
result = obj.normal_method(parameters)

A @ViewScoped bean lives exactly as long as a JSF view. It usually starts with a fresh new GET request, or with a navigation action, and will then live as long as the enduser submits any POST form in the view to an action method which returns null or void (and thus navigates back to the same view). Once you refresh the page, or return a non-null string (even an empty string!) navigation outcome, then the view scope will end.

A @RequestScoped bean lives exactly as long a HTTP request. It will thus be garbaged by end of every request and recreated on every new request, hereby losing all changed properties.

A @ViewScoped bean is thus particularly more useful in rich Ajax-enabled views which needs to remember the (changed) view state across Ajax requests. A @RequestScoped one would be recreated on every Ajax request and thus fail to remember all changed view state. Note that a @ViewScoped bean does not share any data among different browser tabs/windows in the same session like as a @SessionScoped bean. Every view has its own unique @ViewScoped bean.

I set the Advanced->Refspec field to refs/tags/[your tag name]. This seems simpler than the various other suggestions for Refspec, but it worked just fine for me.

UPDATE 23/7/2014 - Actually, after further testing, it turns out this didn't work as expected. It appears that the HEAD version was still being checked out. Please undo this as the accepted answer. I ended up getting a working solution by following the post from gotgenes in this thread (30th March). The issue mentioned in that post of unnecessary triggering of builds was not an issue for me, as my job is triggered from an upstream job, not from polling SCM.

UPDATE APR-2018 - Note in the comments that this does work for one person, and agrees with Jenkins documentation.

Through jQuery.ready function you can specify function that's executed when DOM is loaded. Whole DOM, not any div you want.

So, you should use ready in a bit different way

$.ready(function() {
    createGrid();
});

This is in case when you dont use AJAX to load your div

Copied directly from this answer:

You could write a script in any language you want to automate this (even using nodejs) and then just install a shortcut to that script in the user's %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder

No need for any tweak, you got a native API:

const toNodes = html =>
    new DOMParser().parseFromString(html, 'text/html').body.childNodes[0]

The most concise and intuitive way would be:

var selectElement = document.getElementById('ageselect');_x000D_
_x000D_
for (var age = 12; age <= 100; age++) {_x000D_
  selectElement.add(new Option(age));_x000D_
}

Your age: <select id="ageselect"><option value="">Please select</option></select>

You can also differentiate the name and the value or add items at the start of the list with additional parameters to the used functions:
HTMLSelect?Element?.add(item[, before]);
new Option(text, value, defaultSelected, selected);

== is an operator and equals() is a method.

Operators are generally used for primitive type comparisons and thus == is used for memory address comparison and equals() method is used for comparing objects.

After about a half hour of searching and trying to debug this I was able to figure it out. My situation involved me using the same pem file for two different ec2 instance and it working for one and not the other.

My first instance it worked on was the standard aws linux ami amzn-ami-hvm-2014.03.2.x86_64-ebs. I simply used

ssh -i mypemfile.pem ec2-user@myec2ipaddress 

and it worked.

I then launched a fedora instance Fedora-x86_64-19-20140407-sda and tried the same command but kept getting:

Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

After changing my username from ec2-user to fedora it worked!

ssh -i mypemfile.pem fedora@myec2address

git push -f is a bit destructive because it resets any remote changes that had been made by anyone else on the team. A safer option is {git push --force-with-lease}.

What {--force-with-lease} does is refuse to update a branch unless it is the state that we expect; i.e. nobody has updated the branch upstream. In practice this works by checking that the upstream ref is what we expect, because refs are hashes, and implicitly encode the chain of parents into their value. You can tell {--force-with-lease} exactly what to check for, but by default will check the current remote ref. What this means in practice is that when Alice updates her branch and pushes it up to the remote repository, the ref pointing head of the branch will be updated. Now, unless Bob does a pull from the remote, his local reference to the remote will be out of date. When he goes to push using {--force-with-lease}, git will check the local ref against the new remote and refuse to force the push. {--force-with-lease} effectively only allows you to force-push if no-one else has pushed changes up to the remote in the interim. It's {--force} with the seatbelt on.

To get the modified date on a single file try:

$lastModifiedDate = (Get-Item "C:\foo.tmp").LastWriteTime

To compare with another:

$dateA= $lastModifiedDate 
$dateB= (Get-Item "C:\other.tmp").LastWriteTime

if ($dateA -ge $dateB) {
  Write-Host("C:\foo.tmp was modified at the same time or after C:\other.tmp")
} else {
  Write-Host("C:\foo.tmp was modified before C:\other.tmp")
}

There's no notion of hosts or ip-addresses in the javascript standard library. So you'll have to access some external service to look up hostnames for you.

I recommend hosting a cgi-bin which looks up the ip-address of a hostname and access that via javascript.

I've noticed bizarre behavior with Eclipse version 4.2.1 delivering me this error:

String cannot be resolved to a variable

With this Java code:

if (true)
    String my_variable = "somevalue";
    System.out.println("foobar");

You would think this code is very straight forward, the conditional is true, we set my_variable to somevalue. And it should print foobar. Right?

Wrong, you get the above mentioned compile time error. Eclipse is trying to prevent you from making a mistake by assuming that both statements are within the if statement.

If you put braces around the conditional block like this:

if (true){
    String my_variable = "somevalue"; }
    System.out.println("foobar");

Then it compiles and runs fine. Apparently poorly bracketed conditionals are fair game for generating compile time errors now.

Like this:

import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);

Or adding from an Array/ or multiple literals; wrap to a list, first.

Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b));         // from an array variable
b.addAll( Arrays.asList( 8, 9, 10));  // from literals

To get the intersection:

// copies all from A;  then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print;   r.toString() implied.
System.out.println("A intersect B="+r);

Hope this answer helps. Vote for it!

Similar to Chris Marasti-Georg's example, instead using inline javascript. Essentially add onkeypress to the fields you want the enter key to work with. This example acts on the password field.

<html>
<head><title>title</title></head>

  <form action="" method="get">
  Name: <input type="text" name="name"/><br/>
  Pwd: <input type="password" name="password" onkeypress="if(event.keyCode==13) {javascript:form.submit();}" /><br/>
  <input type="submit" onClick="javascript:form.submit();"/>
</form>
</body>

It is best to use two DateTimePickers for the Job One will be the default for the date section and the second DateTimePicker is for the time portion. Format the second DateTimePicker as follows.

      timePortionDateTimePicker.Format = DateTimePickerFormat.Time;
      timePortionDateTimePicker.ShowUpDown = true;

The Two should look like this after you capture them

To get the DateTime from both these controls use the following code

DateTime myDate = datePortionDateTimePicker.Value.Date + 
                    timePortionDateTimePicker.Value.TimeOfDay; 

To assign the DateTime to both these controls use the following code

datePortionDateTimePicker.Value  = myDate.Date;  
timePortionDateTimePicker.Value  = myDate.TimeOfDay; 

If you don't want to depend on Perl you can also use sed. It's a bit messy, as each character has to be escaped individually. Make a file with the following contents and call it urlencode.sed

s/%/%25/g
s/ /%20/g
s/ /%09/g
s/!/%21/g
s/"/%22/g
s/#/%23/g
s/\$/%24/g
s/\&/%26/g
s/'\''/%27/g
s/(/%28/g
s/)/%29/g
s/\*/%2a/g
s/+/%2b/g
s/,/%2c/g
s/-/%2d/g
s/\./%2e/g
s/\//%2f/g
s/:/%3a/g
s/;/%3b/g
s//%3e/g
s/?/%3f/g
s/@/%40/g
s/\[/%5b/g
s/\\/%5c/g
s/\]/%5d/g
s/\^/%5e/g
s/_/%5f/g
s/`/%60/g
s/{/%7b/g
s/|/%7c/g
s/}/%7d/g
s/~/%7e/g
s/      /%09/g

To use it do the following.

STR1=$(echo "https://www.example.com/change&$ ^this to?%checkthe@-functionality" | cut -d\? -f1)
STR2=$(echo "https://www.example.com/change&$ ^this to?%checkthe@-functionality" | cut -d\? -f2)
OUT2=$(echo "$STR2" | sed -f urlencode.sed)
echo "$STR1?$OUT2"

This will split the string into a part that needs encoding, and the part that is fine, encode the part that needs it, then stitches back together.

You can put that into a sh script for convenience, maybe have it take a parameter to encode, put it on your path and then you can just call:

urlencode https://www.exxample.com?isThisFun=HellNo

This could be a permissions issue.

Normally Python throws NameError if the variable is not defined:

>>> d[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined

However, you've managed to stumble upon a name that already exists in Python.

Because dict is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.

The type of dict is a type. All types are objects in Python. Thus you are actually trying to index into the type object. This is why the error message says that the "'type' object is not subscriptable."

>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable

Note that you can blindly assign to the dict name, but you really don't want to do that. It's just going to cause you problems later.

>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'

The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:

d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))

Try this. It holds the color until another item is clicked.

<style type="text/css">

.activeElem{
 background-color:lightblue
}       
.desactiveElem{
 background-color:none
}       

}

</style>

<script type="text/javascript">
var activeElemId;
function activateItem(elemId) {
 document.getElementById(elemId).className="activeElem";
 if(null!=activeElemId) {
   document.getElementById(activeElemId).className="desactiveElem";
 }
 activeElemId=elemId;

}
</script>

<li id="aaa"><a href="#" onclick="javascript:activateItem('aaa');">AAA</a>
<li id="bbb"><a href="#" onClick="javascript:activateItem('bbb');">BBB</a>
<li id="ccc"><a href="#" onClick="javascript:activateItem('ccc');">CCC</a>

UPDATE

From later versions, there is no need to manually install gulp-util.

Check the new getting started page.

If you still hit this problem try reinstalling your project's local packages:

rm -rf node_modules/
npm install

OUTDATED ANSWER

You also need to install gulp-util:

 npm install gulp-util --save-dev

From gulp docs- getting started (3.5):

Install gulp and gulp-util in your project devDependencies

As mentioned in previous answers, you can cast directly to the underlying datatype (int -> enum type) or parse (string -> enum type).

but beware - there is no .TryParse for enums, so you WILL need a try/catch block around the parse to catch failures.

Encountered same issue, we've had multiple configurations in Xcode project, let's say Debug-Staging, Debug-Production. We then unified those and used only one configuration Debug. But the old one (no longer existing) was stuck in scheme for run phase, so once you tried to run, Xcode showed you this message. Which makes sense as provisioning profiles are set up in build settings based on configuration.

So run scheme looked like this:

While project configurations were setup like this.

Changing scheme to use configuration that is still available in project is what fixed this issue for me.

yes, in a limited sense.

public class DataSet : System.Data.DataSet
{
    public static void SpecialMethod() { }
}

This works but Console doesn't because it's static.

public static class Console
{       
    public static void WriteLine(String x)
    { System.Console.WriteLine(x); }

    public static void WriteBlueLine(String x)
    {
        System.Console.ForegroundColor = ConsoleColor.Blue;
        System.Console.Write(.x);           
    }
}

This works because as long as it's not on the same namespace. The problem is that you have to write a proxy static method for every method that System.Console have. It's not necessarily a bad thing as you can add something like this:

    public static void WriteLine(String x)
    { System.Console.WriteLine(x.Replace("Fck","****")); }

or

 public static void WriteLine(String x)
    {
        System.Console.ForegroundColor = ConsoleColor.Blue;
        System.Console.WriteLine(x); 
    }

The way it works is that you hook something into the standard WriteLine. It could be a line count or bad word filter or whatever. Whenever you just specify Console in your namespace say WebProject1 and import the namespace System, WebProject1.Console will be chosen over System.Console as default for those classes in namespace WebProject1. So this code will turn all the Console.WriteLine calls into blue insofar as you never specified System.Console.WriteLine.

Here's the simplest solution I have come across. I have learnt this from Beginning iOS 5 Development book.

Assuming the number field is called numberField.

1. In ViewController, add the following method:

   -(IBAction)closeKeyboard:(id)sender;
   

2. In ViewController.m, add the following code:

   -(IBAction)closeKeyboard:(id)sender
   {
   
        [numberField resignFirstResponder];
   
   }
   

3. Go back to nib file.

4. Open Utilities pan.
5. Open the Identity inspector under Utilities pan.
6. Click on the View (in nib file) once. Make sure you have not clicked on any of the items in the view. For the sake of clarification, you should see UIView under Class in Identity inspector.
7. Change the class from UIView to UIControl.
8. Open Connection Inspector.
9. Click and drag Touch Down and drop the arrow on File Owner icon. (FYI... File Owner icon is displayed on the left of View and appears as a hollow cube with yellow frame.)
10. Select the method: closeKeyboard.
11. Run the program.

Now when you click anywhere on background of View, you should be able to dismiss the keyboard.

Hope this helps you solve your problem. :-)

In my case, I used an ordinary seekBar and just flipped out the layout.

seekbark_layout.xml - my layout that containts seekbar which we need to make vertical.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rootView"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<SeekBar
    android:id="@+id/seekBar"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:layout_alignParentBottom="true"/>

</RelativeLayout>

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.vgfit.seekbarexample.MainActivity">

<View
    android:id="@+id/headerView"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:background="@color/colorAccent"/>

<View
    android:id="@+id/bottomView"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:layout_alignParentBottom="true"
    android:background="@color/colorAccent"/>

<include
    layout="@layout/seekbar_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_above="@id/bottomView"
    android:layout_below="@id/headerView"/>

 </RelativeLayout>

And in MainActivity I rotate seekbar_layout:

import android.os.Bundle
import android.support.v7.app.AppCompatActivity
import android.widget.RelativeLayout
import kotlinx.android.synthetic.main.seekbar_layout.*


class MainActivity : AppCompatActivity() {

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    rootView.post {
        val w = rootView.width
        val h = rootView.height

        rootView.rotation = 270.0f
        rootView.translationX = ((w - h) / 2).toFloat()
        rootView.translationY = ((h - w) / 2).toFloat()

        val lp = rootView.layoutParams as RelativeLayout.LayoutParams
        lp.height = w
        lp.width = h
        rootView.requestLayout()
    }
}
}

As a result we have necessary vertical seekbar:

try this code

cd /go/to/path
git pull origin master

As @Brian Riley already said you should either remove 1 column in your select

from countrylanguage
join country on countrylanguage.countrycode = country.code
group by countrylanguage.language
order by sum(country.population*countrylanguage.percentage) desc ;

or add it to your grouping

select countrylanguage.language, country.code, sum(country.population*countrylanguage.percentage/100)
from countrylanguage
join country on countrylanguage.countrycode = country.code
group by countrylanguage.language, country.code
order by sum(country.population*countrylanguage.percentage) desc ;

Something like:

find /path/ -type f -exec stat \{} --printf="%y\n" \; | 
     sort -n -r | 
     head -n 1

Explanation:

• the find command will print modification time for every file recursively ignoring directories (according to the comment by IQAndreas you can't rely on the folders timestamps)
• sort -n (numerically) -r (reverse)
• head -n 1: get the first entry

As it turns out, Git is smart enough not to drop a stash if it doesn't apply cleanly. I was able to get to the desired state with the following steps:

1. To unstage the merge conflicts: git reset HEAD . (note the trailing dot)
2. To save the conflicted merge (just in case): git stash
3. To return to master: git checkout master
4. To pull latest changes: git fetch upstream; git merge upstream/master
5. To correct my new branch: git checkout new-branch; git rebase master
6. To apply the correct stashed changes (now 2nd on the stack): git stash apply stash@{1}

Just Set it up like this

{% set active_link = recordtype -%}

You don't even need an MTA. The SMTP protocol is simple enough to directly write it to your SMTP server. You can even communicate over SSL/TLS if you have the OpenSSL package installed. Check this post: https://33hops.com/send-email-from-bash-shell.html

The above is an example on how to send text/html e-mails that will work out of the box. If you want to add attachments the thing can get a bit more complicated, you will need to base64 encode the binary files and embed them between boundaries. THis is a good place to start investigating: http://forums.codeguru.com/showthread.php?418377-Send-Email-w-attachments-using-SMTP

For those who expect JSON and still getting the same error, make sure that you parse your data:

$scope.customers = JSON.parse(data)

Try this - set Ajax call by setting up the header as follows:

var uri = "http://localhost:50869/odata/mydatafeeds"
$.ajax({
    url: uri,
    beforeSend: function (request) {
        request.setRequestHeader("Authorization", "Negotiate");
    },
    async: true,
    success: function (data) {
        alert(JSON.stringify(data));
    },
    error: function (xhr, textStatus, errorMessage) {
        alert(errorMessage);
    }                
});

Then run your code by opening Chrome with the following command line:

chrome.exe --user-data-dir="C:/Chrome dev session" --disable-web-security

Really depends on the overall structure of your document.

If you have:

<div></div>
<div></div>
<div></div>

it may be as simple as traversing through using

mydiv.nextSibling;
mydiv.previousSibling;

However, if the 'next' div could be anywhere in the document you'll need a more complex solution. You could try something using

document.getElementsByTagName("div");

and running through these to get where you want somehow.

If you are doing lots of complex DOM traversing such as this I would recommend looking into a library such as jQuery.

woocommerce_get_product_terms() is now deprecated.

Use wc_get_product_terms() instead.

Example:

global $product;
$koostis = array_shift( wc_get_product_terms( $product->id, 'pa_koostis', array( 'fields' => 'names' ) ) );

Directly from the GitHub project homepage:

Dapper allow you to pass in IEnumerable and will automatically parameterize your query.

connection.Query<int>(
    @"select * 
      from (select 1 as Id union all select 2 union all select 3) as X 
      where Id in @Ids", 
    new { Ids = new int[] { 1, 2, 3 });

Will be translated to:

select * 
from (select 1 as Id union all select 2 union all select 3) as X 
where Id in (@Ids1, @Ids2, @Ids3)

// @Ids1 = 1 , @Ids2 = 2 , @Ids2 = 3

I guess the issue here is that you are updating INV_DISCOUNT and the INV_TOTAL uses the INV_DISCOUNT. so that is the issue here. You can use returning clause of update statement to use the new INV_DISCOUNT and use it to update INV_TOTAL.

this is a generic example let me know if this explains the point i mentioned

CREATE OR REPLACE PROCEDURE SingleRowUpdateReturn
IS
    empName VARCHAR2(50);
    empSalary NUMBER(7,2);      
BEGIN
    UPDATE emp
    SET sal = sal + 1000
    WHERE empno = 7499
    RETURNING ename, sal
    INTO empName, empSalary;

    DBMS_OUTPUT.put_line('Name of Employee: ' || empName);
    DBMS_OUTPUT.put_line('New Salary: ' || empSalary);
END;

With recent Maven versions (3) and recent version of the maven compiler plugin (3.7.0), I notice that adding a source folder with the build-helper-maven-plugin is not required if the folder that contains the source code to add in the build is located in the target folder or a subfolder of it.
It seems that the compiler maven plugin compiles any java source code located inside this folder whatever the directory that contains them.
For example having some (generated or no) source code in target/a, target/generated-source/foo will be compiled and added in the outputDirectory : target/classes.

Linq to SQL Like Operator

This should work:

reload(my.module)

From the Python docs

Reload a previously imported module. The argument must be a module object, so it must have been successfully imported before. This is useful if you have edited the module source file using an external editor and want to try out the new version without leaving the Python interpreter.

If running Python 3.4 and up, do import importlib, then do importlib.reload(nameOfModule).

Don't forget the caveats of using this method:

• When a module is reloaded, its dictionary (containing the module’s global variables) is retained. Redefinitions of names will override the old definitions, so this is generally not a problem, but if the new version of a module does not define a name that was defined by the old version, the old definition is not removed.

• If a module imports objects from another module using from ... import ..., calling reload() for the other module does not redefine the objects imported from it — one way around this is to re-execute the from statement, another is to use import and qualified names (module.*name*) instead.

• If a module instantiates instances of a class, reloading the module that defines the class does not affect the method definitions of the instances — they continue to use the old class definition. The same is true for derived classes.

You could try using "typeid".

This doesn't work for "object" name but YOU know the object name so you'll just have to store it somewhere. The Compiler doesn't care what you namned an object.

Its worth bearing in mind, though, that the output of typeid is a compiler specific thing so even if it produces what you are after on the current platform it may not on another. This may or may not be a problem for you.

The other solution is to create some kind of template wrapper that you store the class name in. Then you need to use partial specialisation to get it to return the correct class name for you. This has the advantage of working compile time but is significantly more complex.

Edit: Being more explicit

template< typename Type > class ClassName
{
public:
    static std::string name()
    {
        return "Unknown";
    }
};

Then for each class somethign liek the following:

template<> class ClassName<MyClass>
{
public:
    static std::string name()
    {
        return "MyClass";
    }
};

Which could even be macro'd as follows:

#define DefineClassName( className ) \
\
template<> class ClassName<className> \
{ \
public: \
    static std::string name() \
    { \
        return #className; \
    } \
}; \

Allowing you to, simply, do

DefineClassName( MyClass );

Finally to Get the class name you'd do the following:

ClassName< MyClass >::name();

Edit2: Elaborating further you'd then need to put this "DefineClassName" macro in each class you make and define a "classname" function that would call the static template function.

Edit3: And thinking about it ... Its obviously bad posting first thing in the morning as you may as well just define a member function "classname()" as follows:

std::string classname()
{
     return "MyClass";
}

which can be macro'd as follows:

DefineClassName( className ) \
std::string classname()  \
{ \
     return #className; \
}

Then you can simply just drop

DefineClassName( MyClass );

into the class as you define it ...

   char *s1, *s2;
   char str[10];

   printf("type a string: ");
   scanf("%s", str);

   s1 = &str[0];
   s2 = &str[2];

   printf("%c\n", *s1);   //use %c instead of %s and *s1 which is the content of position 1
   printf("%c\n", *s2);   //use %c instead of %s and *s3 which is the content of position 1

   return 0;

In Python 3 use input():

input("Press Enter to continue...")

In Python 2 use raw_input():

raw_input("Press Enter to continue...")

This only waits for the user to press enter though.

One might want to use msvcrt ((Windows/DOS only) The msvcrt module gives you access to a number of functions in the Microsoft Visual C/C++ Runtime Library (MSVCRT)):

import msvcrt as m
def wait():
    m.getch()

This should wait for a key press.

Additional info:

in Python 3 raw_input() does not exist

In Python 2 input(prompt) is equivalent to eval(raw_input(prompt))

Without doing a full revamp of the default routing (#/ViewName) environment, I was able to do a slight modification of Cody's tip and got it working great.

the controller

.controller('GeneralCtrl', ['$route', '$routeParams', '$location',
        function($route, $routeParams, $location) {
            ...
            this.goToView = function(viewName){
                $location.url('/' + viewName);
            }
        }]
    );

the view

...
<li ng-click="general.goToView('Home')">HOME</li>
...

What brought me to this solution was when I was attempting to integrate a Kendo Mobile UI widget into an angular environment I was losing the context of my controller and the behavior of the regular anchor tag was also being hijacked. I re-established my context from within the Kendo widget and needed to use a method to navigate...this worked.

Thanks for the previous posts!

Both are DBMS's Product Sql server is an commercial application while MySql is an opensouces application.Both the product include similar feature,however sql server should be used for an enterprise solution ,while mysql might suit a smaller implementation.if you need feature like recovery,replication,granalar security and significant,you need sql server

MySql takes up less spaces on disk, and uses less memory and cpu than does sql server

I'm assuming you want the standard system bell, and don't want to concern yourself with frequencies and durations etc., you just want the standard windows bell.

import winsound
winsound.MessageBeep()

You can also create a search pipe to filter results:

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name : 'searchPipe',
})
export class SearchPipe implements PipeTransform {
  public transform(value, key: string, term: string) {
    return value.filter((item) => {
      if (item.hasOwnProperty(key)) {
        if (term) {
          let regExp = new RegExp('\\b' + term, 'gi');
          return regExp.test(item[key]);
        } else {
          return true;
        }
      } else {
        return false;
      }
    });
  }
}

Use pipe in HTML :

<md-input placeholder="Item name..." [(ngModel)]="search" ></md-input>
<div *ngFor="let item of items | searchPipe:'name':search ">
  {{item.name}}
</div>

Another example with a struct :

package types

import "fmt"

type MyType struct {
    Id   int    
    Name string
}

func (t MyType) String() string {
    return fmt.Sprintf(
    "[%d : %s]",
    t.Id, 
    t.Name)
}

Be careful when using it,
concatenation with '+' doesn't compile :

t := types.MyType{ 12, "Blabla" }

fmt.Println(t) // OK
fmt.Printf("t : %s \n", t) // OK
//fmt.Println("t : " + t) // Compiler error !!!
fmt.Println("t : " + t.String()) // OK if calling the function explicitly

Implicit definition would be to just add the methods / properties, etc. demanded by the interface directly to the class as public methods.

Explicit definition forces the members to be exposed only when you are working with the interface directly, and not the underlying implementation. This is preferred in most cases.

1. By working directly with the interface, you are not acknowledging, and coupling your code to the underlying implementation.
2. In the event that you already have, say, a public property Name in your code and you want to implement an interface that also has a Name property, doing it explicitly will keep the two separate. Even if they were doing the same thing I'd still delegate the explicit call to the Name property. You never know, you may want to change how Name works for the normal class and how Name, the interface property works later on.
3. If you implement an interface implicitly then your class now exposes new behaviours that might only be relevant to a client of the interface and it means you aren't keeping your classes succinct enough (my opinion).

Take a clone of a remote repository and run git branch -a (to show all the branches git knows about). It will probably look something like this:

* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

Here, master is a branch in the local repository. remotes/origin/master is a branch named master on the remote named origin. You can refer to this as either origin/master, as in:

git diff origin/master..master

You can also refer to it as remotes/origin/master:

git diff remotes/origin/master..master

These are just two different ways of referring to the same thing (incidentally, both of these commands mean "show me the changes between the remote master branch and my master branch).

remotes/origin/HEAD is the default branch for the remote named origin. This lets you simply say origin instead of origin/master.

http://www.456bereastreet.com/archive/200704/how_to_prevent_html_tables_from_becoming_too_wide/

But - you don't have a lot of room to spare with your data.

CSS FTW:

<style>
table {
    table-layout:fixed;
}
td{
    overflow:hidden;
    text-overflow: ellipsis;
}
</style>

The solution is to negate your values when you store them in the heap, or invert your object comparison like so:

import heapq

class MaxHeapObj(object):
  def __init__(self, val): self.val = val
  def __lt__(self, other): return self.val > other.val
  def __eq__(self, other): return self.val == other.val
  def __str__(self): return str(self.val)

Example of a max-heap:

maxh = []
heapq.heappush(maxh, MaxHeapObj(x))
x = maxh[0].val  # fetch max value
x = heapq.heappop(maxh).val  # pop max value

But you have to remember to wrap and unwrap your values, which requires knowing if you are dealing with a min- or max-heap.

MinHeap, MaxHeap classes

Adding classes for MinHeap and MaxHeap objects can simplify your code:

class MinHeap(object):
  def __init__(self): self.h = []
  def heappush(self, x): heapq.heappush(self.h, x)
  def heappop(self): return heapq.heappop(self.h)
  def __getitem__(self, i): return self.h[i]
  def __len__(self): return len(self.h)

class MaxHeap(MinHeap):
  def heappush(self, x): heapq.heappush(self.h, MaxHeapObj(x))
  def heappop(self): return heapq.heappop(self.h).val
  def __getitem__(self, i): return self.h[i].val

Example usage:

minh = MinHeap()
maxh = MaxHeap()
# add some values
minh.heappush(12)
maxh.heappush(12)
minh.heappush(4)
maxh.heappush(4)
# fetch "top" values
print(minh[0], maxh[0])  # "4 12"
# fetch and remove "top" values
print(minh.heappop(), maxh.heappop())  # "4 12"

Make sure you have granted permission for both Sender and Receiver to send email and receive email from Unknown sources(External Sources) in Email Account.

import smtplib

#Ports 465 and 587 are intended for email client to email server communication - sending email
server = smtplib.SMTP('smtp.gmail.com', 587)

#starttls() is a way to take an existing insecure connection and upgrade it to a secure connection using SSL/TLS.
server.starttls()

#Next, log in to the server
server.login("#email", "#password")

msg = "Hello! This Message was sent by the help of Python"

#Send the mail
server.sendmail("#Sender", "#Reciever", msg)

If the view is embedded at all in a UIScrollView then you can use the following:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag;
tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeInteractive;

The former will animate the keyboard off screen when the table view is scrolled and the later will hide the keyboard like the stock Messages app.

Note that these are are available on iOS 7.0 or above.

One of reasons why you will get this Notice: Array to string conversion in… is that you are combining group of arrays. Example, sorting out several first and last names.

To echo elements of array properly, you can use the function, implode(separator, array) Example:

implode(' ', $var)

result:

first name[1], last name[1]
first name[2], last name[2]

Your current combination of a POST with an HTTP 204 response is fine.

Using a POST as a universal replacement for a GET is not supported by the RFC, as each has its own specific purpose and semantics.

The purpose of a GET is to retrieve a resource. Therefore, while allowed, an HTTP 204 wouldn't be the best choice since content IS expected in the response. An HTTP 404 Not Found or an HTTP 410 Gone would be better choices if the server was unable to provide the requested resource.

The RFC also specifically calls out an HTTP 204 as an appropriate response for PUT, POST and DELETE, but omits it for GET.

See the RFC for the semantics of GET.

There are other response codes that could also be returned, indicating no content, that would be more appropriate than an HTTP 204.

For example, for a conditional GET you could receive an HTTP 304 Not Modified response which would contain no body content.

You can use the function TIME(h,m,s) of google spreadsheet. If you want to add times to each other (or other arithmetic operations), you can specify either a cell, or a call to TIME, for each input of the formula.

For example:

• B3 = 10:45
• C3 = 20 (minutes)
• D3 = 15 (minutes)
• E3 = 8 (hours)
• F3 = B3+time(E3,C3+D3,0) equals 19:20

Using a for-of on Object.keys()

Like:

let object = {
  "key1": "value1",
  "key2": "value2",
  "key3": "value3"
};

for (let key of Object.keys(object)) {
  console.log(key + " : " + object[key])
}

Well another possible cause of this can be simple line break at end of each line and shebang line If you have been coding in windows IDE its possible that windows has added its own line break at the end of each line and when you try to run it on linux the line break cause problems

An answer for experts only:

    String[] split = all.substring(1, all.length()-1).split(", ");
    List<String> strs = Arrays.asList(split);

A character in Java is a Unicode code-unit which is treated as an unsigned number. So if you perform c = (char)b the value you get is 2^16 - 56 or 65536 - 56.

Or more precisely, the byte is first converted to a signed integer with the value 0xFFFFFFC8 using sign extension in a widening conversion. This in turn is then narrowed down to 0xFFC8 when casting to a char, which translates to the positive number 65480.

From the language specification:

5.1.4. Widening and Narrowing Primitive Conversion

First, the byte is converted to an int via widening primitive conversion (§5.1.2), and then the resulting int is converted to a char by narrowing primitive conversion (§5.1.3).

To get the right point use char c = (char) (b & 0xFF) which first converts the byte value of b to the positive integer 200 by using a mask, zeroing the top 24 bits after conversion: 0xFFFFFFC8 becomes 0x000000C8 or the positive number 200 in decimals.

Above is a direct explanation of what happens during conversion between the byte, int and char primitive types.

If you want to encode/decode characters from bytes, use Charset, CharsetEncoder, CharsetDecoder or one of the convenience methods such as new String(byte[] bytes, Charset charset) or String#toBytes(Charset charset). You can get the character set (such as UTF-8 or Windows-1252) from StandardCharsets.

One way I like to use is:

select ,COUNT()as VAR1 from Table_Name

group by

order by VAR1 desc

limit 1

If it is a "NMake Makefile", that is to say the syntax and command is compatible with NMake, it will work natively on Windows. Usually Makefile.win (the .win suffix) indicates it's a makefile compatible with Windows NMake. So you could try nmake -f Makefile.win.

Often standard Linux Makefiles are provided and NMake looks promising. However, the following link takes a simple Linux Makefile and explains some fundamental issues that one may encounter. It also suggests a few alternatives to handling Linux Makefiles on Windows.

Makefiles in Windows

use var array = entry.split("");

You could try this code:

private float GetBrightestColor(float r, float g, float b) { 
    if (r > g && r > b) {
        return r;
    } else if (g > r && g > b) { 
        return g;
    } else if (b > r && b > g) { 
        return b;
    }
}

The Background property expects a Brush object, not a string. Change the type of the property to Brush and initialize it thus:

Background = new SolidColorBrush(Colors.Red);

According to the spec for locating Schemas

there may or may not be a schema retrievable via the namespace name... User community and/or consumer/provider agreements may establish circumstances in which [trying to retrieve an xsd from the namespace url] is a sensible default strategy

(thanks for being unambiguous, spec!)

and

in case a document author (human or not) created a document with a particular schema in view, and warrants that some or all of the document conforms to that schema, the schemaLocation and noNamespaceSchemaLocation [attributes] are provided.

So basically with specifying just a namespace, your XML "might" be attempted to be validated against an xsd at that location (even if it lacks a schemaLocation attribute), depending on your "community." If you specify a specific schemaLocation, then it basically is implying that the xml document "should" be conformant to said xsd, so "please validate it" (as I read it). My guess is that if you don't do a schemaLocation or noNamespaceSchemaLocation attribute it just "isn't validated" most of the time (based on the other answers, appears java does it this way).

Another wrinkle here is that typically, with xsd validation in java libraries [ex: spring config xml files], if your XML files specifies a particular schemaLocation xsd url in an XML file, like xsi:schemaLocation="http://somewhere http://somewhere/something.xsd" typically within one of your dependency jars it will contain a copy of that xsd file, in its resources section, and spring has a "mapping" capability saying to treat that xsd file as if it maps to the url http://somewhere/something.xsd (so you never end up going to web and downloading the file, it just exists locally). See also https://stackoverflow.com/a/41225329/32453 for slightly more info.

As stated in the other answers:

• MOV will grab the data at the address inside the brackets and place that data into the destination operand.
• LEA will perform the calculation of the address inside the brackets and place that calculated address into the destination operand. This happens without actually going out to the memory and getting the data. The work done by LEA is in the calculating of the "effective address".

Because memory can be addressed in several different ways (see examples below), LEA is sometimes used to add or multiply registers together without using an explicit ADD or MUL instruction (or equivalent).

Since everyone is showing examples in Intel syntax, here are some in AT&T syntax:

MOVL 16(%ebp), %eax       /* put long  at  ebp+16  into eax */
LEAL 16(%ebp), %eax       /* add 16 to ebp and store in eax */

MOVQ (%rdx,%rcx,8), %rax  /* put qword at  rcx*8 + rdx  into rax */
LEAQ (%rdx,%rcx,8), %rax  /* put value of "rcx*8 + rdx" into rax */

MOVW 5(%bp,%si), %ax      /* put word  at  si + bp + 5  into ax */
LEAW 5(%bp,%si), %ax      /* put value of "si + bp + 5" into ax */

MOVQ 16(%rip), %rax       /* put qword at rip + 16 into rax                 */
LEAQ 16(%rip), %rax       /* add 16 to instruction pointer and store in rax */

MOVL label(,1), %eax      /* put long at label into eax            */
LEAL label(,1), %eax      /* put the address of the label into eax */

save()- As the method name suggests, hibernate save() can be used to save entity to database. We can invoke this method outside a transaction. If we use this without transaction and we have cascading between entities, then only the primary entity gets saved unless we flush the session.

persist()-Hibernate persist is similar to save (with transaction) and it adds the entity object to the persistent context, so any further changes are tracked. If the object properties are changed before the transaction is committed or session is flushed, it will also be saved into database. Also, we can use persist() method only within the boundary of a transaction, so it’s safe and takes care of any cascaded objects. Finally, persist doesn't return anything so we need to use the persisted object to get the generated identifier value.

Yes, and no. Despite what some other replies have said, the C compiler is required to perform conversions for sprintf(), and all other variadic functions, as follows:

• char => int
• short => int
• float => double

(and signed/unsigned variants of the above integral types)

It does this precisely because sprintf() (and the other print()-family functions) would be unusable without it. (Of course, they're pretty unusable as it is.)

But you cannot assume any other conversions, and your code will have undefined behaviour - read: crash! - if you do it.

You have to set the associatedEmployee on the Vehicle before persisting the Employee.

Employee newEmployee = new Employee("matt");
vehicle1.setAssociatedEmployee(newEmployee);
vehicles.add(vehicle1);

newEmployee.setVehicles(vehicles);

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

This is the solution I came up with for a class project:

public static String theMonth(int month){
    String[] monthNames = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};
    return monthNames[month];
}

The number you pass in comes from a Calendar.MONTH call.

The problem is that you mapped your servlet to /register.html and it expects POST method, because you implemented only doPost() method. So when you open register.html page, it will not open html page with the form but servlet that handles the form data.

Alternatively when you submit POST form to non-existing URL, web container will display 405 error (method not allowed) instead of 404 (not found).

To fix:

<servlet-mapping>
    <servlet-name>Register</servlet-name>
    <url-pattern>/Register</url-pattern>
</servlet-mapping>

The command (or the URL in it) to add the github repository as a remote isn't quite correct. If I understand your repository name correctly, it should be;

git remote add demo_app '[email protected]:levelone/demo_app.git'

You should use "Object.assign()"

There's no need to reinvent the wheel for such a simple use case of shallow merging.

The Object.assign() method is used to copy the values of all enumerable own properties from one or more source objects to a target object. It will return the target object.

var o1 = { a: 1 };
var o2 = { b: 2 };
var o3 = { c: 3 };

var obj = Object.assign(o1, o2, o3);
console.log(obj); // { a: 1, b: 2, c: 3 }
console.log(o1);  // { a: 1, b: 2, c: 3 }, target object itself is changed

Even the folks from Node.js say so:

_extend was never intended to be used outside of internal NodeJS modules. The community found and used it anyway. It is deprecated and should not be used in new code. JavaScript comes with very similar built-in functionality through Object.assign.

Update:

You could use the spread operator

Since version 8.6, it's possible to natively use the spread operator in Node.js. Example below:

let o1 = { a: 1 };
let o2 = { b: 2 };
let obj = { ...o1, ...o2 }; // { a: 1, b: 2 }

Object.assign still works, though.

^{PS1: If you are actually interested in deep merging (in which internal object data -- in any depth -- is recursively merged), you can use packages like deepmerge, assign-deep or lodash.merge, which are pretty small and simple to use.}

^{PS2: Keep in mind that Object.assign doesn't work with 0.X versions of Node.js. If you are working with one of those versions (you really shouldn't by now), you could use require("util")._extend as shown in the Node.js link above -- for more details, check tobymackenzie's answer to this same question.}

In addition to previous answers, if your menu items are Categories and you want to highlight them when navigating through posts, check also for current-post-ancestor:

add_filter('nav_menu_css_class' , 'special_nav_class' , 10 , 2);

function special_nav_class ($classes, $item) {
    if (in_array('current-post-ancestor', $classes) || in_array('current-page-ancestor', $classes) || in_array('current-menu-item', $classes) ){
        $classes[] = 'active ';
    }
    return $classes;
}

Here's a solution for your specific problem that doesn't require for loops or external commands like ls, find and the like.

if [ "$(echo xorg-x11-fonts*)" != "xorg-x11-fonts*" ]; then
    printf "BLAH"
fi

As you can see, it's just a tad more complicated than what you were hoping for, and relies on the fact that if the shell is not able to expand the glob, it means no files with that glob exist and echo will output the glob as is, which allows us to do a mere string comparison to check whether any of those files exist at all.

If we were to generalize the procedure, though, we should take into account the fact that files might contain spaces within their names and/or paths and that the glob char could rightfully expand to nothing (in your example, that would be the case of a file whose name is exactly xorg-x11-fonts).

This could be achieved by the following function, in bash.

function doesAnyFileExist {
   local arg="$*"
   local files=($arg)
   [ ${#files[@]} -gt 1 ] || [ ${#files[@]} -eq 1 ] && [ -e "${files[0]}" ]
}

Going back to your example, it could be invoked like this.

if doesAnyFileExist "xorg-x11-fonts*"; then
    printf "BLAH"
fi

Glob expansion should happen within the function itself for it to work properly, that's why I put the argument in quotes and that's what the first line in the function body is there for: so that any multiple arguments (which could be the result of a glob expansion outside the function, as well as a spurious parameter) would be coalesced into one. Another approach could be to raise an error if there's more than one argument, yet another could be to ignore all but the 1st argument.

The second line in the function body sets the files var to an array constituted by all the file names that the glob expanded to, one for each array element. It's fine if the file names contain spaces, each array element will contain the names as is, including the spaces.

The third line in the function body does two things:

1. It first checks whether there's more than one element in the array. If so, it means the glob surely got expanded to something (due to what we did on the 1st line), which in turn implies that at least one file matching the glob exist, which is all we wanted to know.

2. If at step 1. we discovered that we got less than 2 elements in the array, then we check whether we got one and if so we check whether that one exist, the usual way. We need to do this extra check in order to account for function arguments without glob chars, in which case the array contains only one, unexpanded, element.

Step-by-Step way to do this:

1. Install Android SDK
2. Start the emulator by going to $SDK_root/emulator.exe
3. Go to command prompt and go to the directory $SDK_root/platform-tools (or else add the path to windows environment)
4. Type in the command adb install
5. Bingo. Your app should be up and running on the emulator

Sometimes this kind of error happens when you create tables with different database users and try to SELECT with a different user. You can grant all privileges using below query.

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA schema_name TO username;

And also you can grant access for DML statements

GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA schema_name TO username;

ENV['RAILS_ENV'] is now deprecated.

You should use Rails.env which is clearly much nicer.

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

With Chinese text, I tried to use the Charset UTF-16 and lucklily it work.

Hope this could help!

PrintWriter out = new PrintWriter( file, "UTF-16" );

I also had the same errors with fontawesome's fonts. Then I downloaded the lastest fontawesome's fonts and replace to the old fonts. And the errors are gone.

In general, a condition in the WHERE clause of an SQL query can reference only a single row. The context of a WHERE clause is evaluated before any order has been defined by an ORDER BY clause, and there is no implicit order to an RDBMS table.

You can use a derived table to join each row to the group of rows with a lesser id value, and produce the sum of each sum group. Then test where the sum meets your criterion.

CREATE TABLE MyTable ( id INT PRIMARY KEY, cash INT );

INSERT INTO MyTable (id, cash) VALUES
  (1, 200), (2, 301), (3, 101), (4, 700);

SELECT s.*
FROM (
  SELECT t.id, SUM(prev.cash) AS cash_sum
  FROM MyTable t JOIN MyTable prev ON (t.id > prev.id)
  GROUP BY t.id) AS s
WHERE s.cash_sum >= 500
ORDER BY s.id
LIMIT 1;

Output:

+----+----------+
| id | cash_sum |
+----+----------+
|  3 |      501 |
+----+----------+

It sounds like this is referring to something else than you think. In what context are you using it?

The this keyword is usually only used within a callback function of an event-handler, when you loop over a set of elements, or similar. In that context it refers to a particular DOM-element, and can be used the way you do.

If you only want to access that particular button (outside any callback or loop) and don't have any other elements that use the btn-info class, you could do something like:

parseInt($(".btn-info").data('votevalue'), 10);

You could also assign the element an ID, and use that to select on, which is probably a safer way, if you want to be sure that only one element match your selector.

If you want to learn your data summary (df) provides the min, 1st quantile, median and mean, 3rd quantile and max of numerical columns and the frequency of the top levels of the factor columns.

Following command will execute exactly testSaveAndDrop test.

phpunit --filter '/::testSaveAndDrop$/' escalation/EscalationGroupTest.php

<form enctype="multipart/form-data">
   <input name="file" type="file" />
   <input type="submit" value="Upload" />
</form>
<script>
$('input[type=file]').change(function(){
    var file = this.files[0];
    name = file.name;
    size = file.size;
    type = file.type;
    //your validation
});
</script>

You can easily achieve what you want using the appendix package. Here's a sample file that shows you how. The key is the titletoc option when calling the package. It takes whatever value you've defined in \appendixname and the default value is Appendix.

\documentclass{report}
\usepackage[titletoc]{appendix}
\begin{document}
\tableofcontents

\chapter{Lorem ipsum}
\section{Dolor sit amet}
\begin{appendices}
  \chapter{Consectetur adipiscing elit}
  \chapter{Mauris euismod}
\end{appendices}
\end{document}

The output looks like

To obtain all the rows that contains an empty cell in in a particular column.

DF_new_row=DF_raw.loc[DF_raw['columnname']=='']

This will give the subset of DF_raw, which satisfy the checking condition.

Do you mean these hex values?

.glyphicon-asterisk:before{content:"\2a";}
.glyphicon-plus:before{content:"\2b";}
.glyphicon-euro:before{content:"\20ac";}
...

You can find these in glyphicons.css here:

http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css

(If you only want to know the Glyphicons classes: http://getbootstrap.com/components/#glyphicons)

I think that your problem is actually with not correctly indenting init function.It should be like this

class MyClass():
     def __init__(self, filename):
          pass

     def parse_file():
          pass

var $th = $td.closest('tbody').prev('thead').find('> tr > th:eq(' + $td.index() + ')');

Or a little bit simplified

var $th = $td.closest('table').find('th').eq($td.index());

If anyone is searching for useState() hooks update for object

- Through Input

        const [state, setState] = useState({ fName: "", lName: "" });
        const handleChange = e => {
            const { name, value } = e.target;
            setState(prevState => ({
                ...prevState,
                [name]: value
            }));
        };

        <input
            value={state.fName}
            type="text"
            onChange={handleChange}
            name="fName"
        />
        <input
            value={state.lName}
            type="text"
            onChange={handleChange}
            name="lName"
        />
   ***************************

 - Through onSubmit or button click
    
        setState(prevState => ({
            ...prevState,
            fName: 'your updated value here'
         }));

There 3 functions you want to look at here:

• LARGE - Returns the k-th largest value in a data set.
• INDEX - Returns a value or the reference to a value from within a table or range.
• MATCH - The MATCH function searches for a specified item in a range of cells, and then returns the relative position of that item in the range.

I ran a sample in Excel with your OPS values in Column B and Players in Column C, see below:

• In Cells A13 to A17, the values 1 to 5 were inserted to specify the nth highest value.
• In Cell B13, the following formula was added: =LARGE($B$2:$B$11, A13)
• In Cell C13, the following formula was added: =INDEX($C$2:$C$11,MATCH(B13,$B$2:$B$11,0))
• These formulae get the highest ranking OPS and Player based on the value in A13.
• Simply select and drag to copy these formulae down to the next 4 cells which will reference the corresponding ranking in Column A.

This should work. Your code works for me, like for Tamás and Manoj Govindan. It looks like you could try to update Matplotlib. If you can't update Matplotlib (for instance if you have insufficient administrative rights), maybe using a different backend with matplotlib.use() could help.

Perhaps an example will help:

git rm --cached asd
git commit -m "the file asd is gone from the repository"

versus

git reset HEAD -- asd
git commit -m "the file asd remains in the repository"

Note that if you haven't changed anything else, the second commit won't actually do anything.

Using Task, futurize, and a traversable List, you can simply do

async function printFiles() {
  const files = await getFiles();

  List(files).traverse( Task.of, f => readFile( f, 'utf-8'))
    .fork( console.error, console.log)
}

Here is how you'd set this up

import fs from 'fs';
import { futurize } from 'futurize';
import Task from 'data.task';
import { List } from 'immutable-ext';

const future = futurizeP(Task)
const readFile = future(fs.readFile)

Another way to have structured the desired code would be

const printFiles = files => 
  List(files).traverse( Task.of, fn => readFile( fn, 'utf-8'))
    .fork( console.error, console.log)

Or perhaps even more functionally oriented

// 90% of encodings are utf-8, making that use case super easy is prudent

// handy-library.js
export const readFile = f =>
  future(fs.readFile)( f, 'utf-8' )

export const arrayToTaskList = list => taskFn => 
  List(files).traverse( Task.of, taskFn ) 

export const readFiles = files =>
  arrayToTaskList( files, readFile )

export const printFiles = files => 
  readFiles(files).fork( console.error, console.log)

Then from the parent function

async function main() {
  /* awesome code with side-effects before */
  printFiles( await getFiles() );
  /* awesome code with side-effects after */
}

If you really wanted more flexibility in encoding, you could just do this (for fun, I'm using the proposed Pipe Forward operator )

import { curry, flip } from 'ramda'

export const readFile = fs.readFile 
  |> future,
  |> curry,
  |> flip

export const readFileUtf8 = readFile('utf-8')

PS - I didn't try this code on the console, might have some typos... "straight freestyle, off the top of the dome!" as the 90s kids would say. :-p

Using regexes for this purpose is the wrong approach. Since you are using python you have a really awesome library available to extract parts from HTML documents: BeautifulSoup.

This helped me get to my answer. There are two php.ini files located, in my case, for wamp. One is under the php folder and the other one is in the C:\wamp\bin\apache\Apachex.x.x\bin folder. When connecting to SQL through sqlsrv_connect function, we are referring to the php.ini file in the apache folder. Add the following (as per your version) to this file:

extension=c:/wamp/bin/php/php5.4.16/ext/php_sqlsrv_53_ts.dll

Another option is to hide based on bootstraps "sr-only" class. If you wrap the text in a span with the class "sr-only" then the text will not be displayed, but screen readers will still have access to it. So you would have:

<li><a href="somehwere"><span class="sr-only">Link text</span></a></li>

If you are not using bootstrap, still keep the above, but also add the below css to define the "sr-only" class:

.sr-only {position: absolute;  width: 1px;  height: 1px;  padding: 0;  margin: -1px;  overflow: hidden;  clip: rect(0 0 0 0);  border: 0; }

Credit to Jens Lehmann for this one - if you keep source directories separate to your compiler project files and build output, you could simplify your .gitignore by negating it:

path/to/build/directory/*
!*.sln
!*.vcproj

You don't say what language(s) you're using, but the above should work for C++ projects.

On Arch Linux I was able to fix this by running sudo locale-gen

It looks like something has changed over the years and now Apple recommends to use strong in general. The evidence on their WWDC session is in session 407 - Implementing UI Designs in Interface Builder and starts at 32:30. My note from what he says is (almost, if not exactly, quoting him):

• outlet connections in general should be strong especially if we connect a subview or constraint that is not always retained by the view hierarchy

• weak outlet connection might be needed when creating custom views that has some reference to something back up in the view hierarchy and in general it is not recommended

In other wards it should be always strong now as long as some of our custom view doesn't create a retain cycle with some of the view up in the view hierarchy

EDIT :

Some may ask the question. Does keeping it with a strong reference doesn't create a retain cycle as the root view controller and the owning view keeps the reference to it? Or why that changed happened? I think the answer is earlier in this talk when they describe how the nibs are created from the xib. There is a separate nib created for a VC and for the view. I think this might be the reason why they change the recommendations. Still it would be nice to get a deeper explanation from Apple.

Hi this is odd way but try it once

1. Read the file content into a string
2. print the string and check whether you are getting proper XML or not
3. you can use XMLDocument.LoadXML(xmlstring)

I try with your code and same XML without adding any XML declaration it works for me

XmlDocument doc = new XmlDocument();
        doc.Load(@"H:\WorkSpace\C#\TestDemos\TestDemos\XMLFile1.xml");
        XmlNodeList nodes = doc.GetElementsByTagName("Product");
        XmlNode node = null;
        foreach (XmlNode n in nodes)
        {
            Console.WriteLine("HI");
        }

Its working perfectly fine

Another possibility is to use separate lines to set up Make variables when a rule fires.

For example, here is a makefile with two rules. If a rule fires, it creates a temp dir and sets TMP to the temp dir name.

PHONY = ruleA ruleB display

all: ruleA

ruleA: TMP = $(shell mktemp -d testruleA_XXXX)
ruleA: display

ruleB: TMP = $(shell mktemp -d testruleB_XXXX)
ruleB: display

display:
    echo ${TMP}

Running the code produces the expected result:

$ ls
Makefile
$ make ruleB
echo testruleB_Y4Ow
testruleB_Y4Ow
$ ls
Makefile  testruleB_Y4Ow

loop to the last element of the linked list which have next pointer to null then modify the next pointer to point to a new node which has the data=object and next pointer = null

str.erase(0, str.find_first_not_of("\t\n\v\f\r ")); // left trim
str.erase(str.find_last_not_of("\t\n\v\f\r ") + 1); // right trim

Super late to this thread but here goes.

TLDR; Add the following block in your AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

 ....
    // HERE: replace "Verlag" with your font
  [[UILabel appearance] setFont:[UIFont fontWithName:@"Verlag" size:17.0]];
  ....
}

Walkthrough of the whole flow.

A few ways you can do this outside of using a plugin like react-native-global-props so Ill walk you though step by step.

Adding fonts to platforms.

How to add the font to IOS project

First let's create a location for our assets. Let's make the following directory at our root.

```

ios/
static/
       fonts/

```

Now let's add a "React Native" NPM in our package.json

  "rnpm": {
    "static": [
   "./static/fonts/"
    ]
  }

Now we can run "react-native link" to add our assets to our native apps.

Verifying or doing manually.

That should add your font names into the projects .plist (for VS code users run code ios/*/Info.plist to confirm)

Here let's assume Verlag is the font you added, it should look something like this:

     <dict>
   <plist>
      .....
      <key>UIAppFonts</key>
      <array>
         <string>Verlag Bold Italic.otf</string>
         <string>Verlag Book Italic.otf</string>
         <string>Verlag Light.otf</string>
         <string>Verlag XLight Italic.otf</string>
         <string>Verlag XLight.otf</string>
         <string>Verlag-Black.otf</string>
         <string>Verlag-BlackItalic.otf</string>
         <string>Verlag-Bold.otf</string>
         <string>Verlag-Book.otf</string>
         <string>Verlag-LightItalic.otf</string>
      </array>
      ....    
</dict>
</plist>

Now that you mapped them, now let's make sure they are actually there and being loaded (this is also how you'd do it manually).

Go to "Build Phase" > "Copy Bundler Resource", If it didn't work you'll a manually add under them here.

Get Font Names (recognized by XCode)

First open your XCode logs, like:

Then you can add the following block in your AppDelegate.m to log the names of the Fonts and the Font Family.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    .....


  for (NSString* family in [UIFont familyNames])
  {
    NSLog(@"%@", family);
    for (NSString* name in [UIFont fontNamesForFamilyName: family])
    {
      NSLog(@" %@", name);
    }
  }

  ...
}

Once you run you should find your fonts if loaded correctly, here we found ours in logs like this:

2018-05-07 10:57:04.194127-0700 MyApp[84024:1486266] Verlag
2018-05-07 10:57:04.194266-0700 MyApp[84024:1486266]  Verlag-Book
2018-05-07 10:57:04.194401-0700 MyApp[84024:1486266]  Verlag-BlackItalic
2018-05-07 10:57:04.194516-0700 MyApp[84024:1486266]  Verlag-BoldItalic
2018-05-07 10:57:04.194616-0700 MyApp[84024:1486266]  Verlag-XLight
2018-05-07 10:57:04.194737-0700 MyApp[84024:1486266]  Verlag-Bold
2018-05-07 10:57:04.194833-0700 MyApp[84024:1486266]  Verlag-Black
2018-05-07 10:57:04.194942-0700 MyApp[84024:1486266]  Verlag-XLightItalic
2018-05-07 10:57:04.195170-0700 MyApp[84024:1486266]  Verlag-LightItalic
2018-05-07 10:57:04.195327-0700 MyApp[84024:1486266]  Verlag-BookItalic
2018-05-07 10:57:04.195510-0700 MyApp[84024:1486266]  Verlag-Light

So now we know it loaded the Verlag family and are the fonts inside that family

• Verlag-Book
• Verlag-BlackItalic
• Verlag-BoldItalic
• Verlag-XLight
• Verlag-Bold
• Verlag-Black
• Verlag-XLightItalic
• Verlag-LightItalic
• Verlag-BookItalic
• Verlag-Light

These are now the case sensitive names we can use in our font family we can use in our react native app.

Got -'em now set default font.

Then to set a default font to add your font family name in your AppDelegate.m with this line

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

 ....
    // ADD THIS LINE (replace "Verlag" with your font)

  [[UILabel appearance] setFont:[UIFont fontWithName:@"Verlag" size:17.0]];
  ....
}

Done.

My own experience has been that it's best to stick to one of two kinds of assembly references:

• A 'local' assembly in the current build directory
• An assembly in the GAC

I've found (much like you've described) other methods to either be too easily broken or have annoying maintenance requirements.

Any assembly I don't want to GAC, has to live in the execution directory. Any assembly that isn't or can't be in the execution directory I GAC (managed by automatic build events).

This hasn't given me any problems so far. While I'm sure there's a situation where it won't work, the usual answer to any problem has been "oh, just GAC it!". 8 D

Hope that helps!

Boost has regex in it.

That should fill the bill

Try this:

mWebView.setLayerType(View.LAYER_TYPE_HARDWARE, null);

Thanks for all reply.

Because I have to write a decimal number in a xml file I have find out the problem. In this discussion I have learned that xml file standard use dot for decimal value and this is culture independent. So my solution is write dot decimal number in a xml file and convert the readed string from the same xml file mystring.Replace(".", ","); Thanks Agat for suggestion to research the problem in xml context and ? ? ? ? ? ? because I didn't know visual studio doesn't respect the culture settings I have in my code.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|00D900",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(12, 18)
);

Use Assembly.GetTypes. For example:

Assembly mscorlib = typeof(string).Assembly;
foreach (Type type in mscorlib.GetTypes())
{
    Console.WriteLine(type.FullName);
}

I had similar problems when moving from Visual Studio 2012 → Visual Studio 2013. The IDE would lock up after almost every click or save, and building would take several times longer. None of the solutions listed here helped.

What finally did help was moving my projects to a local drive. Visual Studio 2012 had no problems storing my projects on a network share, but Visual Studio 2013 for some reason couldn't handle it.

You're setting overflow: hidden. This will hide anything that's too large for the <div>, meaning scrollbars won't be shown. Give your <div> an explicit width and/or height, and change overflow to auto:

.scroll {
   width: 200px;
   height: 400px;
   overflow: scroll;
}

If you only want to show a scrollbar if the content is longer than the <div>, change overflow to overflow: auto. You can also only show one scrollbar by using overflow-y or overflow-x.

NetBeans 8.2 - Cannot locate java installation in specified jdkhome?

Answer: Edit the netbeans.conf file.

Close NetBeans, start Notepad or another text editor as Administrator. Right click on the Notepad application and choose "Run as administrator" and then open netbeans.conf with it. Change netbeans_jdkhome=”C:\Program Files...whatever”.

Your file has Windows line endings, which is confusing Linux.

Remove the spurious CR characters. You can do it with the following command:

 $ sed -i -e 's/\r$//' setup.sh

Classes are like categories. Many HTML elements can belong to a class, and an HTML element can have more than one class. Classes are used to apply general styles or styles that can be applied across multiple HTML elements.

IDs are identifiers. They're unique; no one else is allowed to have that same ID. IDs are used to apply unique styles to an HTML element.

I use IDs and classes in this fashion:

<div id="header">
  <h1>I am a header!</h1>
  <p>I am subtext for a header!</p>
</div>
<div id="content">
  <div class="section">
    <p>I am a section!</p>
  </div>
  <div class="section special">
    <p>I am a section!</p>
  </div>
  <div class="section">
    <p>I am a section!</p>
  </div>
</div>

In this example, the header and content sections can be styled via #header and #content. Each section of the content can be applied a common style through #content .section. Just for kicks, I added a "special" class for the middle section. Suppose you wanted a particular section to have a special styling. This can be achieved with the .special class, yet the section still inherits the common styles from #content .section.

When I do JavaScript or CSS development, I typically use IDs to access/manipulate a very specific HTML element, and I use classes to access/apply styles to a broad range of elements.

I think the question asker is (was) thinking that git bash is a command like git init or git checkout. Git bash is not a command, it is an interface. I will also assume the asker is not a linux user because bash is very popular the unix/linux world. The name "bash" is an acronym for "Bourne Again SHell". Bash is a text-only command interface that has features which allow automated scripts to be run. A good analogy would be to compare bash to the new PowerShell interface in Windows7/8. A poor analogy (but one likely to be more readily understood by more people) is the combination of the command prompt and .BAT (batch) command files from the days of DOS and early versions of Windows.

Bit late to the party, but I was having issues getting any of these to work with a React.Select dropdown as the option clicked would no longer be contained within the parent I was looking to click out of by the time onClick was fired.

I got round this issue by using:

componentDidMount() {
    document.addEventListener('mousedown', this.onClick );
}

componentWillUnmount() {
    document.removeEventListener('mousedown', this.onClick );
}

onClick = (event) => {
    if(!event.path.includes(this.detectOutsideClicksDiv)) {
        // Do stuff here
    }
}

Keep in mind that as of PHP 5.5.0 the mysql_connect() function is deprecated, and it is completely removed in PHP 7

More info can be found on the php documentation:

Quote:

Warning
This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
* mysqli_connect()
* PDO::__construct()

I had the same problem for a long time. I just managed to resolve it.

So, you need to select your Path, like the others said above. What I did:

Open a command window. Write set path=C:\Python24 (put the location and the version for your python). Now type python, It should work.

The annoying part with this is that you have to type it every time you open the CMD.

I tried to do the permanent one (with the changes in the Environmental variables) but for me its not working.

I did this once for my project, to close one application and open another application.

    System.Threading.Thread newThread;
    Form1 frmNewForm = new Form1;

   newThread = new System.Threading.Thread(new System.Threading.ThreadStart(frmNewFormThread));
this.Close();
        newThread.SetApartmentState(System.Threading.ApartmentState.STA);
        newThread.Start();

And add the following Method. Your newThread.Start will call this method.

    public void frmNewFormThread)()
    {

        Application.Run(frmNewForm);

    }

The approach recommended by the ASP.Net Core team is to use the new policy design which is fully documented here. The basic idea behind the new approach is to use the new [Authorize] attribute to designate a "policy" (e.g. [Authorize( Policy = "YouNeedToBe18ToDoThis")] where the policy is registered in the application's Startup.cs to execute some block of code (i.e. ensure the user has an age claim where the age is 18 or older).

The policy design is a great addition to the framework and the ASP.Net Security Core team should be commended for its introduction. That said, it isn't well-suited for all cases. The shortcoming of this approach is that it fails to provide a convenient solution for the most common need of simply asserting that a given controller or action requires a given claim type. In the case where an application may have hundreds of discrete permissions governing CRUD operations on individual REST resources ("CanCreateOrder", "CanReadOrder", "CanUpdateOrder", "CanDeleteOrder", etc.), the new approach either requires repetitive one-to-one mappings between a policy name and a claim name (e.g. options.AddPolicy("CanUpdateOrder", policy => policy.RequireClaim(MyClaimTypes.Permission, "CanUpdateOrder));), or writing some code to perform these registrations at run time (e.g. read all claim types from a database and perform the aforementioned call in a loop). The problem with this approach for the majority of cases is that it's unnecessary overhead.

While the ASP.Net Core Security team recommends never creating your own solution, in some cases this may be the most prudent option with which to start.

The following is an implementation which uses the IAuthorizationFilter to provide a simple way to express a claim requirement for a given controller or action:

public class ClaimRequirementAttribute : TypeFilterAttribute
{
    public ClaimRequirementAttribute(string claimType, string claimValue) : base(typeof(ClaimRequirementFilter))
    {
        Arguments = new object[] {new Claim(claimType, claimValue) };
    }
}

public class ClaimRequirementFilter : IAuthorizationFilter
{
    readonly Claim _claim;

    public ClaimRequirementFilter(Claim claim)
    {
        _claim = claim;
    }

    public void OnAuthorization(AuthorizationFilterContext context)
    {
        var hasClaim = context.HttpContext.User.Claims.Any(c => c.Type == _claim.Type && c.Value == _claim.Value);
        if (!hasClaim)
        {
            context.Result = new ForbidResult();
        }
    }
}


[Route("api/resource")]
public class MyController : Controller
{
    [ClaimRequirement(MyClaimTypes.Permission, "CanReadResource")]
    [HttpGet]
    public IActionResult GetResource()
    {
        return Ok();
    }
}

In my case it was that the C: drive was out of space. Ensure that you have enough space available.

The reason for this error is that there are other database before the wrong operation led to the current database operation can not be carried out(i use google translation to translate my chinese to english)

If the indexes are not in sequence, or if the indexes are not consecutive, the code in the other solutions listed here will break. A solution that would work somewhat better might be:

function in_array(needle, haystack) {
    for(var i in haystack) {
        if(haystack[i] == needle) return true;
    }
    return false;
}

And, as a bonus, here's the equivalent to PHP's array_search (for finding the key of the element in the array:

function array_search(needle, haystack) {
    for(var i in haystack) {
        if(haystack[i] == needle) return i;
    }
    return false;
}

This is a great way to make the video fit a banner, you might need to tweak this a little for full screen but should be ok. 100% CSS.

    position: absolute;_x000D_
    top: 50%;_x000D_
    left: 50%;_x000D_
    z-index: 1;_x000D_
    min-width: 100%;_x000D_
    min-height: 100%;_x000D_
    width: auto;_x000D_
    height: auto;_x000D_
    transform: translate(-50%, -50%);

The new (in 2014) tidyr package also does this simply, with gather()/spread() being the terms for melt/cast.

Edit: Now, in 2019, tidyr v 1.0 has launched and set spread and gather on a deprecation path, preferring instead pivot_wider and pivot_longer, which you can find described in this answer. Read on if you want a brief glimpse into the brief life of spread/gather.

library(tidyr)
spread(dat1, key = numbers, value = value)

From github,

tidyr is a reframing of reshape2 designed to accompany the tidy data framework, and to work hand-in-hand with magrittr and dplyr to build a solid pipeline for data analysis.

Just as reshape2 did less than reshape, tidyr does less than reshape2. It's designed specifically for tidying data, not the general reshaping that reshape2 does, or the general aggregation that reshape did. In particular, built-in methods only work for data frames, and tidyr provides no margins or aggregation.

This code also works.

$(".circle").hover(function() {$(this).hide(200).show(200);});

    border-radius:50px;_x000D_

    color:black;_x000D_
    line-height:100px;_x000D_
    text-align:center;_x000D_
    background:yellow_x000D_
}

Make sure you're calling super() as the first thing in your constructor.

You should set this for setAuthorState method

class ManageAuthorPage extends Component {

  state = {
    author: { id: '', firstName: '', lastName: '' }
  };

  constructor(props) {
    super(props);
    this.handleAuthorChange = this.handleAuthorChange.bind(this);
  } 

  handleAuthorChange(event) {
    let {name: fieldName, value} = event.target;

    this.setState({
      [fieldName]: value
    });
  };

  render() {
    return (
      <AuthorForm
        author={this.state.author}
        onChange={this.handleAuthorChange}
      />
    );
  }
}

Another alternative based on arrow function:

class ManageAuthorPage extends Component {

  state = {
    author: { id: '', firstName: '', lastName: '' }
  };

  handleAuthorChange = (event) => {
    const {name: fieldName, value} = event.target;

    this.setState({
      [fieldName]: value
    });
  };

  render() {
    return (
      <AuthorForm
        author={this.state.author}
        onChange={this.handleAuthorChange}
      />
    );
  }
}

the below code works like magic to me >>

td { white-space:pre-line }
