This gets asked a lot. Basically, no there isn't, not for .NET 4.0. You have to do it manually at the start of each new thread (or ThreadPool function). You could perhaps store the culture name (or just the culture object) in a static field to save having to hit the DB, but that's about it.

To get the 2 chars ISO 639-1 language identifier use:

System.Threading.Thread.CurrentThread.CurrentCulture.TwoLetterISOLanguageName;

In addition @Fredrik Mörk's great answer on strings, to add localization to a form do the following:

• Set the form's property "Localizable" to true
• Change the form's Language property to the language you want (from a nice drop-down with them all in)
• Translate the controls in that form and move them about if need be (squash those really long full French sentences in!)

Edit: This MSDN article on Localizing Windows Forms is not the original one I linked ... but might shed more light if needed. (the old one has been taken away)

Try:

 DateTime.TryParseExact(txtStartDate.Text, formats, 
        System.Globalization.CultureInfo.InvariantCulture,
        System.Globalization.DateTimeStyles.None, out startDate)

Use CultureInfo class to change your culture info.

var dutchCultureInfo = CultureInfo.CreateSpecificCulture("nl-NL");
var date1 = DateTime.ParseExact(date, "dd.MM.yyyy HH:mm:ss", dutchCultureInfo);

With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.

try this

provider = new CultureInfo("en-US");
DateTime.ParseExact("9/1/2009", "M/d/yyyy", provider);

Bye.

I use the following mechanism in my code

  public static int GetDecimalLength(string tempValue)
    {
        int decimalLength = 0;
        if (tempValue.Contains('.') || tempValue.Contains(','))
        {
            char[] separator = new char[] { '.', ',' };
            string[] tempstring = tempValue.Split(separator);

            decimalLength = tempstring[1].Length;
        }
        return decimalLength;
    }

decimal input=3.376; var instring=input.ToString();

call GetDecimalLength(instring)

I was getting this error

https://docs.google.com/file/d/0B-dUcqacTOLPcmI3SENMZFBLWG8/edit?usp=drivesdk

but I have done some coding into htdocs/index.php and made this like wamp homepage some thing like this

https://docs.google.com/file/d/0B-dUcqacTOLPVC1ORS1saGdOclU/edit?usp=drivesdk

You can't. If you add a member variable of type T to the class (you don't even have to initialise it), you could use that to recover the type.

I figured out how to use multiple left outer joins in VB.NET using LINQ to SQL:

Dim db As New ContractDataContext()

Dim query = From o In db.Orders _
            Group Join v In db.Vendors _
            On v.VendorNumber Equals o.VendorNumber _
            Into ov = Group _
            From x In ov.DefaultIfEmpty() _
            Group Join s In db.Status _
            On s.Id Equals o.StatusId Into os = Group _
            From y In os.DefaultIfEmpty() _
            Where o.OrderNumber >= 100000 And o.OrderNumber <= 200000 _
            Select Vendor_Name = x.Name, _
                   Order_Number = o.OrderNumber, _
                   Status_Name = y.StatusName

You must add your keyListener to every component that you need. Only the component with the focus will send these events. For instance, if you have only one TextBox in your JFrame, that TextBox has the focus. So you must add a KeyListener to this component as well.

The process is the same:

myComponent.addKeyListener(new KeyListener ...);

Note: Some components aren't focusable like JLabel.

For setting them to focusable you need to:

myComponent.setFocusable(true);

First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.

If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
  If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
    'do something
  End If
End If

You can always take the CTE, (Common Tabular Expression), approach.

;WITH updateCTE AS
(
    SELECT ID, TITLE 
    FROM HOLD_TABLE
    WHERE ID = 101
)

UPDATE updateCTE
SET TITLE = 'TEST';

With Eloquent its very easy to retrieve relational data. Checkout the following example with your scenario in Laravel 5.

We have three models:

1) Article (belongs to user and category)

2) Category (has many articles)

3) User (has many articles)

1) Article.php

<?php

namespace App\Models;
 use Eloquent;

class Article extends Eloquent{

    protected $table = 'articles';

    public function user()
    {
        return $this->belongsTo('App\Models\User');
    }

    public function category()
    {
        return $this->belongsTo('App\Models\Category');
    }

}

2) Category.php

<?php

namespace App\Models;

use Eloquent;

class Category extends Eloquent
{
    protected $table = "categories";

    public function articles()
    {
        return $this->hasMany('App\Models\Article');
    }

}

3) User.php

<?php

namespace App\Models;
use Eloquent;

class User extends Eloquent
{
    protected $table = 'users';

    public function articles()
    {
        return $this->hasMany('App\Models\Article');
    }

}

You need to understand your database relation and setup in models. User has many articles. Category has many articles. Articles belong to user and category. Once you setup the relationships in Laravel, it becomes easy to retrieve the related information.

For example, if you want to retrieve an article by using the user and category, you would need to write:

$article = \App\Models\Article::with(['user','category'])->first();

and you can use this like so:

//retrieve user name 
$article->user->user_name  

//retrieve category name 
$article->category->category_name

In another case, you might need to retrieve all the articles within a category, or retrieve all of a specific user`s articles. You can write it like this:

$categories = \App\Models\Category::with('articles')->get();

$users = \App\Models\Category::with('users')->get();

You can learn more at http://laravel.com/docs/5.0/eloquent

You are trying to join Person_Fear.PersonID onto Person_Fear.FearID - This doesn't really make sense. You probably want something like:

SELECT Persons.Name, Persons.SS, Fears.Fear FROM Persons
LEFT JOIN Person_Fear
    INNER JOIN Fears
    ON Person_Fear.FearID = Fears.FearID
ON Person_Fear.PersonID = Persons.PersonID

This joins Persons onto Fears via the intermediate table Person_Fear. Because the join between Persons and Person_Fear is a LEFT JOIN, you will get all Persons records.

Alternatively:

SELECT Persons.Name, Persons.SS, Fears.Fear FROM Persons
LEFT JOIN Person_Fear ON Person_Fear.PersonID = Persons.PersonID
LEFT JOIN Fears ON Person_Fear.FearID = Fears.FearID

unicode('foo,bar').translate(dict([[ord(char), u''] for char in u',']))

You can pass your component as a prop and use the same way you would use a component.

function General(props) {
    ...
    return (<props.substitute a={A} b={B} />);
}

function SpecificA(props) { ... }
function SpecificB(props) { ... }

<General substitute=SpecificA />
<General substitute=SpecificB />

Try this

java -jar <jar-file-name>.jar

You can also use eval:

FOO=bar eval 'somecommand someargs | somecommand2'

Since this answer with eval doesn't seem to please everyone, let me clarify something: when used as written, with the single quotes, it is perfectly safe. It is good as it will not launch an external process (like the accepted answer) nor will it execute the commands in an extra subshell (like the other answer).

As we get a few regular views, it's probably good to give an alternative to eval that will please everyone, and has all the benefits (and perhaps even more!) of this quick eval “trick”. Just use a function! Define a function with all your commands:

mypipe() {
    somecommand someargs | somecommand2
}

and execute it with your environment variables like this:

FOO=bar mypipe

Using a single PowerShell command to retrieve the file ending:

powershell -nologo "& "Get-Content -Wait c:\logFile.log -Tail 10"

It applies to PowerShell 3.0 and newer.

Another option is to create a file called TAIL.CMD with this code:

powershell -nologo "& "Get-Content -Wait %1 -Tail %2"

Incidentally, .ogv files are video, so "video/ogg", .ogg files are Vorbis audio, so "audio/ogg" and .oga files are general Ogg audio, so also "audio/ogg". Checked in Firefox and work. "application/ogg" is deprecated for all audio or video uses. See http://www.rfc-editor.org/rfc/rfc5334.txt

I recently came across The FubuCore Command line parsing implementation I really like it, the reasons being:

• it's easy to use - although I couldn't find a documentation for it, the FubuCore solution also provides a project containing a nice set of Unit Tests that speak more about the functionality than any documentation could
• it has a nice object oriented design, no code repetition or other such things that I used to have in my command line parsing apps
• it's declarative: you basically write classes for the Commands and sets of parameters and decorate them with attributes to set various options (e.g. name, description, mandatory/optional)
• the library even prints a nice Usage Graph, based on these definitions

Below is a simple example on how to use this. To illustrate the usage, I've written a simple utility that has two commands: - add (adds an object to a list - an object consists of a name(string), value(int) and a boolean flag) - list (lists all the currently added objects)

First of all, I wrote a Command class for the 'add' command:

[Usage("add", "Adds an object to the list")]
[CommandDescription("Add object", Name = "add")]
public class AddCommand : FubuCommand<CommandInput>
{
    public override bool Execute(CommandInput input)
    {
        State.Objects.Add(input); // add the new object to an in-memory collection

        return true;
    }
}

This command takes a CommandInput instance as parameter, so I define that next:

public class CommandInput
{
    [RequiredUsage("add"), Description("The name of the object to add")]
    public string ObjectName { get; set; }

    [ValidUsage("add")]
    [Description("The value of the object to add")]
    public int ObjectValue { get; set; }

    [Description("Multiply the value by -1")]
    [ValidUsage("add")]
    [FlagAlias("nv")]
    public bool NegateValueFlag { get; set; }
}

The next command is 'list', which is implemented as follows:

[Usage("list", "List the objects we have so far")]
[CommandDescription("List objects", Name = "list")]
public class ListCommand : FubuCommand<NullInput>
{
    public override bool Execute(NullInput input)
    {
        State.Objects.ForEach(Console.WriteLine);

        return false;
    }
}

The 'list' command takes no parameters, so I defined a NullInput class for this:

public class NullInput { }

All that's left now is to wire this up in the Main() method, like this:

    static void Main(string[] args)
    {
        var factory = new CommandFactory();
        factory.RegisterCommands(typeof(Program).Assembly);

        var executor = new CommandExecutor(factory);

        executor.Execute(args);
    }

The program works as expected, printing hints about the correct usage in case any commands are invalid:

  ------------------------
    Available commands:
  ------------------------
     add -> Add object
    list -> List objects
  ------------------------

And a sample usage for the 'add' command:

Usages for 'add' (Add object)
  add <objectname> [-nv]

  -------------------------------------------------
    Arguments
  -------------------------------------------------
     objectname -> The name of the object to add
    objectvalue -> The value of the object to add
  -------------------------------------------------

  -------------------------------------
    Flags
  -------------------------------------
    [-nv] -> Multiply the value by -1
  -------------------------------------

You can do it more simply, guaranteeing that your .gitconfig is left in a meaningful state:

Using Git version v1.8.0 and above

git push -u hub master when pushing, or:
git branch -u hub/master

OR

(This will set the remote for the currently checked-out branch to hub/master)
git branch --set-upstream-to hub/master

OR

(This will set the remote for the branch named branch_name to hub/master)
git branch branch_name --set-upstream-to hub/master

If you're using v1.7.x or earlier

you must use --set-upstream:
git branch --set-upstream master hub/master

class Enum {
  constructor (...vals) {
    vals.forEach( val => {
      const CONSTANT = Symbol(val);
      Object.defineProperty(this, val.toUpperCase(), {
        get () {
          return CONSTANT;
        },
        set (val) {
          const enum_val = "CONSTANT";
          // generate TypeError associated with attempting to change the value of a constant
          enum_val = val;
        }
      });
    });
  }
}

Example of usage:

const COLORS = new Enum("red", "blue", "green");

EDIT: This answer is correct for version 0.2.10. As @Alexander Vasilyev pointed out it doesn't work in version 0.2.14.

Another reason to use $state.params is when you need to extract query parameters like this:

$stateProvider.state('a', {
  url: 'path/:id/:anotherParam/?yetAnotherParam',
  controller: 'ACtrl',
});

module.controller('ACtrl', function($stateParams, $state) {
  $state.params; // has id, anotherParam, and yetAnotherParam
  $stateParams;  // has id and anotherParam
}

InputStream is used for reading, OutputStream for writing. They are connected as decorators to one another such that you can read/write all different types of data from all different types of sources.

For example, you can write primitive data to a file:

File file = new File("C:/text.bin");
file.createNewFile();
DataOutputStream stream = new DataOutputStream(new FileOutputStream(file));
stream.writeBoolean(true);
stream.writeInt(1234);
stream.close();

To read the written contents:

File file = new File("C:/text.bin");
DataInputStream stream = new DataInputStream(new FileInputStream(file));
boolean isTrue = stream.readBoolean();
int value = stream.readInt();
stream.close();
System.out.printlin(isTrue + " " + value);

You can use other types of streams to enhance the reading/writing. For example, you can introduce a buffer for efficiency:

DataInputStream stream = new DataInputStream(
    new BufferedInputStream(new FileInputStream(file)));

You can write other data such as objects:

MyClass myObject = new MyClass(); // MyClass have to implement Serializable
ObjectOutputStream stream = new ObjectOutputStream(
    new FileOutputStream("C:/text.obj"));
stream.writeObject(myObject);
stream.close();

You can read from other different input sources:

byte[] test = new byte[] {0, 0, 1, 0, 0, 0, 1, 1, 8, 9};
DataInputStream stream = new DataInputStream(new ByteArrayInputStream(test));
int value0 = stream.readInt();
int value1 = stream.readInt();
byte value2 = stream.readByte();
byte value3 = stream.readByte();
stream.close();
System.out.println(value0 + " " + value1 + " " + value2 + " " + value3);

For most input streams there is an output stream, also. You can define your own streams to reading/writing special things and there are complex streams for reading complex things (for example there are Streams for reading/writing ZIP format).

It is only required if you aren't using the default values for version and encoding (which you are in that example).

In my case, i made separate method for local files, in this file: src/Illuminate/Filesystem/FilesystemAdapter.php

    /**
 * Get the local path for the given filename.
 * @param $path
 * @return string
 */
public function localPath($path)
{
    $adapter = $this->driver->getAdapter();
    if ($adapter instanceof LocalAdapter) {
        return $adapter->getPathPrefix().$path;
    } else {
        throw new RuntimeException('This driver does not support retrieving local path');
    }
}

then, i create pull request to framework, but it still not merged into main core yet: https://github.com/laravel/framework/pull/13605 May be someone merge this one))

start "" AcroRd32.exe /A "page=207" "C:\Users\abc\Desktop\abc xyz def\abc def xyz 2015.pdf"

You may try this, I did it finally, it works!

If you really want to do this, create an HttpServletRequestWrapper.

public class AddableHttpRequest extends HttpServletRequestWrapper {

   private HashMap params = new HashMap();

   public AddableingHttpRequest(HttpServletRequest request) {
           super(request);
   }

   public String getParameter(String name) {
           // if we added one, return that one
           if ( params.get( name ) != null ) {
                 return params.get( name );
           }
           // otherwise return what's in the original request
           HttpServletRequest req = (HttpServletRequest) super.getRequest();
           return validate( name, req.getParameter( name ) );
   }

   public void addParameter( String name, String value ) {
           params.put( name, value );
   }

}

Update:

The original answer makes it difficult (and in some cases impossible) to correctly handle promise rejections. The correct solution is to use Promise.all:

const [someResult, anotherResult] = await Promise.all([someCall(), anotherCall()]);

Original answer:

Just make sure you call both functions before you await either one:

// Call both functions
const somePromise = someCall();
const anotherPromise = anotherCall();

// Await both promises    
const someResult = await somePromise;
const anotherResult = await anotherPromise;

I got the same error when I am using robot framework (Selenium based framework) in a Docker instance. The reason was docker was using cached google-chrome-stable_current_amd64.deb for Chrome but it has installed latest chrome driver which was a later version.

Then I used below command and error resolved.

docker-compose build --no-cache

Hope this helps someone.

Please try CURRENT_TIME() or now() functions

"INSERT INTO contactinfo (name, email, subject, date, comments)
VALUES ('$name', '$email', '$subject', NOW(), '$comments')"

OR

"INSERT INTO contactinfo (name, email, subject, date, comments)
VALUES ('$name', '$email', '$subject', CURRENT_TIME(), '$comments')"

OR you could try with PHP date function here:

$date = date("Y-m-d H:i:s");

I think the documentation is reasonably helpful!

If you read it again, it says that adding open graph elements on your website will make your website act as a facebook page and you'll get the ability to publish updates to them etc.

So I think it's up to you - you can either just have a page with no OG elements, which is less work but also less 'rewarding' for you.

If you do use og, then set type to: blog

Finally: fb:admins or fb:app_id - A comma-separated list of either the Facebook IDs of page administrators or a Facebook Platform application ID. At a minimum, include only your own Facebook ID.

So just put your own fbid in there. As a tip, you can easily get this by looking at the url of your profile photo on facebook.

We got this error after having to change our domain administrator password.

Paresh Mayani's answer is mostly correct. Simply use a Broadcast Intent to let the system and all the other apps choose in what way the content is going to be shared.

To share text use the following code:

String message = "Text I want to share.";
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, message);

startActivity(Intent.createChooser(share, "Title of the dialog the system will open"));

From https://spark.apache.org/docs/1.5.1/api/java/org/apache/spark/sql/DataFrame.html, use join:

Inner equi-join with another DataFrame using the given column.

PersonDf.join(ProfileDf,$"personId")

OR

PersonDf.join(ProfileDf,PersonDf("personId") === ProfileDf("personId"))

Update:

You can also save the DFs as temp table using df.registerTempTable("tableName") and you can write sql queries using sqlContext.

I implemented it in the following way. I wanted a generic MakeRequest method that could call my API and receive content for the body of the request - and also deserialise the response into the desired type. I create a Dictionary<string, string> object to house the content to be submitted, and then set the HttpRequestMessage Content property with it:

Generic method to call the API:

    private static T MakeRequest<T>(string httpMethod, string route, Dictionary<string, string> postParams = null)
    {
        using (var client = new HttpClient())
        {
            HttpRequestMessage requestMessage = new HttpRequestMessage(new HttpMethod(httpMethod), $"{_apiBaseUri}/{route}");

            if (postParams != null)
                requestMessage.Content = new FormUrlEncodedContent(postParams);   // This is where your content gets added to the request body


            HttpResponseMessage response = client.SendAsync(requestMessage).Result;

            string apiResponse = response.Content.ReadAsStringAsync().Result;
            try
            {
                // Attempt to deserialise the reponse to the desired type, otherwise throw an expetion with the response from the api.
                if (apiResponse != "")
                    return JsonConvert.DeserializeObject<T>(apiResponse);
                else
                    throw new Exception();
            }
            catch (Exception ex)
            {
                throw new Exception($"An error ocurred while calling the API. It responded with the following message: {response.StatusCode} {response.ReasonPhrase}");
            }
        }
    }

Call the method:

    public static CardInformation ValidateCard(string cardNumber, string country = "CAN")
    { 
        // Here you create your parameters to be added to the request content
        var postParams = new Dictionary<string, string> { { "cardNumber", cardNumber }, { "country", country } };
        // make a POST request to the "cards" endpoint and pass in the parameters
        return MakeRequest<CardInformation>("POST", "cards", postParams);
    }

Xampp I guess you're using MySQL.

mysql_fetch_array($result);  

And make sure $result is not empty.

Based on @Nathan's answer above, but without needing to "remove the final union" and with the option to sort the output, I use the following SQL. It generates another SQL statement which then just run:

select CONCAT( 'select * from (\n', group_concat( single_select SEPARATOR ' UNION\n'), '\n ) Q order by Q.exact_row_count desc') as sql_query
from (
    SELECT CONCAT(
        'SELECT "', 
        table_name, 
        '" AS table_name, COUNT(1) AS exact_row_count
        FROM `', 
        table_schema,
        '`.`',
        table_name, 
        '`'
    ) as single_select
    FROM INFORMATION_SCHEMA.TABLES 
    WHERE table_schema = 'YOUR_SCHEMA_NAME'
      and table_type = 'BASE TABLE'
) Q 

You do need a sufficiently large value of group_concat_max_len server variable but from MariaDb 10.2.4 it should default to 1M.

You can use the wordwrap() function then explode on newline and take the first part, if you don't want to split words.

$str = 'Stack Overflow is as frictionless and painless to use as we could make it.';
$str = wordwrap($str, 28);
$str = explode("\n", $str);
$str = $str[0] . '...';

Source: https://stackoverflow.com/a/1104329/1060423

If you don't care about splitting words, then simply use the php substr function.

echo substr($str, 0, 28) . '...';

Kafka Tool is a GUI application for managing and using Apache Kafka clusters. It provides an intuitive UI that allows one to quickly view objects within a Kafka cluster as well as the messages stored in the topics of the cluster.

Just to add to what Cade said, this is usually a front-end display thing and should therefore be handled there. I know that sometimes it's easier to write something 100% in SQL for things like file export or other "SQL only" solutions, but most of the times this concatenation should be handled in your display layer.

Running this bash command works for me by running chmod 755 gradlew as sometimes file properties changed upon moving from one OS to another (Windows, Linux and Mac).

In my case there was no log whatsoever.

6. Have fun!

Following steps were for older versions(<1.0) of Android Studio

4. In the middle column Click on Android SDK (with Android icon) OR click + on the top if you don't see an entry with Android icon.

5. Change SDK Home Path and select valid Target.

My suggestion would be

$value = $_POST["myfield"];

$Query = Database::Prepare("SELECT * FROM TABLE WHERE MYFIELD LIKE ?");
$Query->Execute(array("%".$value."%"));

you are showing your popup too early. You may post a delayed runnable for showatlocation in Onresume , Give it a try

Edit: This post seems to have the same problem answered Problems creating a Popup Window in Android Activity

Collection is the main interface of Java Collections hierarchy and List(Sequence) is one of the sub interfaces that defines an ordered collection.

I tried this code working for me,get image directly from url

      private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
      ImageView bmImage;
      public DownloadImageTask(ImageView bmImage) {
          this.bmImage = bmImage;
      }

      protected Bitmap doInBackground(String... urls) {
          String urldisplay = urls[0];
          Bitmap mIcon11 = null;
          try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            mIcon11 = BitmapFactory.decodeStream(in);
          } catch (Exception e) {
              Log.e("Error", e.getMessage());
              e.printStackTrace();
          }
          return mIcon11;
      }

      protected void onPostExecute(Bitmap result) {
          bmImage.setImageBitmap(result);
      }
    }

use inside onCreate() method

new DownloadImageTask((ImageView) findViewById(R.id.image)) .execute("http://scoopak.com/wp-content/uploads/2013/06/free-hd-natural-wallpapers-download-for-pc.jpg");

If you're a Cygwin user, you can append the following to your ~/.bashrc file:

stty lnext ^q stop undef start undef

And the following to your ~/.inputrc file:

"\C-v": paste-from-clipboard
"\C-C": copy-to-clipboard

Restart your Cygwin terminal.

(Note, I've used an uppercase C for copy, since CTRL+c is assigned to the break function on most consoles. Season to taste.)

A non-lodash way to solve this in a fairly readable and efficient manner:

function filterByKeys(obj, keys = []) {_x000D_
  const filtered = {}_x000D_
  keys.forEach(key => {_x000D_
    if (obj.hasOwnProperty(key)) {_x000D_
      filtered[key] = obj[key]_x000D_
    }_x000D_
  })_x000D_
  return filtered_x000D_
}_x000D_
_x000D_
const myObject = {_x000D_
  a: 1,_x000D_
  b: 'bananas',_x000D_
  d: null_x000D_
}_x000D_
_x000D_
const result = filterByKeys(myObject, ['a', 'd', 'e']) // {a: 1, d: null}_x000D_
console.log(result)

string management is an expensive process. keeping strings immutable allows repeated strings to be reused, rather than re-created.

Definition: An imperative language uses a sequence of statements to determine how to reach a certain goal. These statements are said to change the state of the program as each one is executed in turn.

Examples: Java is an imperative language. For example, a program can be created to add a series of numbers:

 int total = 0;
 int number1 = 5;
 int number2 = 10;
 int number3 = 15;
 total = number1 + number2 + number3; 

Each statement changes the state of the program, from assigning values to each variable to the final addition of those values. Using a sequence of five statements the program is explicitly told how to add the numbers 5, 10 and 15 together.

Functional languages: The functional programming paradigm was explicitly created to support a pure functional approach to problem solving. Functional programming is a form of declarative programming.

Advantages of Pure Functions: The primary reason to implement functional transformations as pure functions is that pure functions are composable: that is, self-contained and stateless. These characteristics bring a number of benefits, including the following: Increased readability and maintainability. This is because each function is designed to accomplish a specific task given its arguments. The function does not rely on any external state.

Easier reiterative development. Because the code is easier to refactor, changes to design are often easier to implement. For example, suppose you write a complicated transformation, and then realize that some code is repeated several times in the transformation. If you refactor through a pure method, you can call your pure method at will without worrying about side effects.

Easier testing and debugging. Because pure functions can more easily be tested in isolation, you can write test code that calls the pure function with typical values, valid edge cases, and invalid edge cases.

For OOP People or Imperative languages:

Object-oriented languages are good when you have a fixed set of operations on things and as your code evolves, you primarily add new things. This can be accomplished by adding new classes which implement existing methods and the existing classes are left alone.

Functional languages are good when you have a fixed set of things and as your code evolves, you primarily add new operations on existing things. This can be accomplished by adding new functions which compute with existing data types and the existing functions are left alone.

Cons:

It depends on the user requirements to choose the way of programming, so there is harm only when users don’t choose the proper way.

When evolution goes the wrong way, you have problems:

• Adding a new operation to an object-oriented program may require editing many class definitions to add a new method
• Adding a new kind of thing to a functional program may require editing many function definitions to add a new case.

I found this here:

On windows (win xp), the parent process will not finish until the longtask.py has finished its work. It is not what you want in CGI-script. The problem is not specific to Python, in PHP community the problems are the same.

The solution is to pass DETACHED_PROCESS Process Creation Flag to the underlying CreateProcess function in win API. If you happen to have installed pywin32 you can import the flag from the win32process module, otherwise you should define it yourself:

DETACHED_PROCESS = 0x00000008

pid = subprocess.Popen([sys.executable, "longtask.py"],
                       creationflags=DETACHED_PROCESS).pid

It's called String#start_with?, not String#startswith: In Ruby, the names of boolean-ish methods end with ? and the words in method names are separated with an _. Not sure where the s went, personally, I'd prefer String#starts_with? over the actual String#start_with?

It's because you cannot access protected member data through its class instance. You should correct your code as follows:

namespace homeworkchap8
{
    class main
    {    
        static void Main(string[] args)
        {    
            SteelClubs myClub = new SteelClubs();
            Console.WriteLine("How far to the hole?");
            myClub.mydistance = Console.ReadLine();
            Console.WriteLine("what club are you going to hit?");
            myClub.myclub = Console.ReadLine();
            myClub.SwingClub();

            SteelClubs mycleanclub = new SteelClubs();
            Console.WriteLine("\nDid you clean your club after?");
            mycleanclub.mycleanclub = Console.ReadLine();
            mycleanclub.clean();

            SteelClubs myScoreonHole = new SteelClubs();
            Console.WriteLine("\nWhat hole are you on?");
            myScoreonHole.myhole = Console.ReadLine();
            Console.WriteLine("What did you score on the hole?");
            myScoreonHole.myscore = Console.ReadLine();
            Console.WriteLine("What is the par of the hole?");
            myScoreonHole.parhole = Console.ReadLine();

            myScoreonHole.score();

            Console.ReadKey();    
        }
    }

As documented in ?legend you do this like so:

plot(1:10,type = "n")
abline(v=seq(1,10,1), col='grey', lty='dotted')
legend(1, 5, "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",box.lwd = 0,box.col = "white",bg = "white")
points(1:10,1:10)

Line breaks are achieved with the new line character \n. Making the points still visible is done simply by changing the order of plotting. Remember that plotting in R is like drawing on a piece of paper: each thing you plot will be placed on top of whatever's currently there.

Note that the legend text is cut off because I made the plot dimensions smaller (windows.options does not exist on all R platforms).

just call "onclick"!

here's an example html:

<div id="c" onclick="alert('hello')">Click me!</div>
<div onclick="document.getElementById('c').onclick()">Fake click the previous link!</div>

Have you tried sp_help?

sp_help 'TableName'

Probably, more intuitive way would be like this

if type(e) is list:
    print('Found a list element inside the list') 

By default, docker uses AF_INET6 sockets which can be used for both IPv4 and IPv6 connections. This causes netstat to report an IPv6 address for the listening address.

Or even easier and without the need to create a filter: use PHP's mb_strimwidth to truncate a string to a certain width (length). Just make sure you use one of the get_ syntaxes. For example with the content:

<?php $content = get_the_content(); echo mb_strimwidth($content, 0, 400, '...');?>

This will cut the string at 400 characters and close it with .... Just add a "read more"-link to the end by pointing to the permalink with get_permalink().

<a href="<?php the_permalink() ?>">Read more </a>

Of course you could also build the read more in the first line. Than just replace '...' with '<a href="' . get_permalink() . '">[Read more]</a>'

I have Python 2 and Python 3 installed on my computer. For some strange reason I have in the sys.path of Python 3 also a path to the sitepackage library directory of Python2 when the re module is called. If I run Python 3 and import enum and print(enum.__file__) the system does not show this Python 2 path to site-packages. So a very rough and dirty hack is, to directly modify the module in which enum is imported (follow the traceback paths) and insert the following code just before importing enum:

import sys
for i, p in enumerate(sys.path):
    if "python27" in p.lower() or "python2.7" in p.lower(): sys.path.pop(i)
import enum

That solved my problem.

Threads are absolutely not the answer here. They will provide both process and kernel bottlenecks, as well as throughput limits that are not acceptable if the overall goal is "the fastest way".

A little bit of twisted and its asynchronous HTTP client would give you much better results.

You do this via attributes on the properties, like this:

[Description("Test text displayed in the textbox"),Category("Data")] 
public string Text {
  get => myInnerTextBox.Text;
  set => myInnerTextBox.Text = value;
}

The category is the heading under which the property will appear in the Visual Studio Properties box. Here's a more complete MSDN reference, including a list of categories.

you can use ajax calls to call different methods without a postback

$.ajax({
    type: "POST",
     url: "@(Url.Action("Action", "Controller"))",
     data: {id: 'id', id1: 'id1' },
     contentType: "application/json; charset=utf-8",
     cache: false,
     async: true,
     success: function (result) {
        //do something
     }
});

React Router v6

allows to use both nested routes (like in v3) and separate, splitted routes (v4, v5).

Nested Routes

Keep all routes in one place for small/medium size apps:

<Routes>
  <Route path="/" element={<Home />} >
    <Route path="user" element={<User />} /> 
    <Route path="dash" element={<Dashboard />} /> 
  </Route>
</Routes>

const App = () => {
  return (
    <BrowserRouter>
      <Routes>
        // /js is start path of stack snippet
        <Route path="/js" element={<Home />} >
          <Route path="user" element={<User />} />
          <Route path="dash" element={<Dashboard />} />
        </Route>
      </Routes>
    </BrowserRouter>
  );
}

const Home = () => {
  const location = useLocation()
  return (
    <div>
      <p>URL path: {location.pathname}</p>
      <Outlet />
      <p>
        <Link to="user" style={{paddingRight: "10px"}}>user</Link>
        <Link to="dash">dashboard</Link>
      </p>
    </div>
  )
}

const User = () => <div>User profile</div>
const Dashboard = () => <div>Dashboard</div>

ReactDOM.render(<App />, document.getElementById("root"));

<div id="root"></div>
    <script src="https://unpkg.com/[email protected]/umd/react.production.min.js"></script>
    <script src="https://unpkg.com/[email protected]/umd/react-dom.production.min.js"></script>
    <script src="https://unpkg.com/[email protected]/umd/history.production.min.js"></script>
    <script src="https://unpkg.com/[email protected]/umd/react-router.production.min.js"></script>
    <script src="https://unpkg.com/[email protected]/umd/react-router-dom.production.min.js"></script>
    <script>var { BrowserRouter, Routes, Route, Link, Outlet, useNavigate, useLocation } = window.ReactRouterDOM;</script>

Alternative: Define your routes as plain JavaScript objects via useRoutes.

Separate Routes

You can use separates routes to meet requirements of larger apps like code splitting:

// inside App.jsx:
<Routes>
  <Route path="/*" element={<Home />} />
</Routes>

// inside Home.jsx:
<Routes>
  <Route path="user" element={<User />} />
  <Route path="dash" element={<Dashboard />} />
</Routes>

const App = () => {
  return (
    <BrowserRouter>
      <Routes>
        // /js is start path of stack snippet
        <Route path="/js/*" element={<Home />} />
      </Routes>
    </BrowserRouter>
  );
}

const Home = () => {
  const location = useLocation()
  return (
    <div>
      <p>URL path: {location.pathname}</p>
      <Routes>
        <Route path="user" element={<User />} />
        <Route path="dash" element={<Dashboard />} />
      </Routes>
      <p>
        <Link to="user" style={{paddingRight: "5px"}}>user</Link>
        <Link to="dash">dashboard</Link>
      </p>
    </div>
  )
}

const User = () => <div>User profile</div>
const Dashboard = () => <div>Dashboard</div>

ReactDOM.render(<App />, document.getElementById("root"));

<div id="root"></div>
    <script src="https://unpkg.com/[email protected]/umd/react.production.min.js"></script>
    <script src="https://unpkg.com/[email protected]/umd/react-dom.production.min.js"></script>
    <script src="https://unpkg.com/[email protected]/umd/history.production.min.js"></script>
    <script src="https://unpkg.com/[email protected]/umd/react-router.production.min.js"></script>
    <script src="https://unpkg.com/[email protected]/umd/react-router-dom.production.min.js"></script>
    <script>var { BrowserRouter, Routes, Route, Link, Outlet, useNavigate, useLocation } = window.ReactRouterDOM;</script>

Bootstrap 4

This is what worked for me:

I created my own _custom_theme.scss file with content similar to:

/* To simplify I'm only changing the primary color */
$theme-colors: ( "primary":#ffd800);

Added it to the top of the file bootstrap.scss and recompiled (In my case I had it in a folder called !scss)

@import "../../../!scss/_custom_theme.scss";
@import "functions";
@import "variables";
@import "mixins";

$('.btn').click(function() {
    $('#td_id').removeClass();
    $('#td_id').addClass('newClass');
});

or

$('.btn').click(function() {
    $('#td_id').removeClass().addClass('newClass');
});

Updated for 2019: As previously suggested, in the latest Eclipse, go to "Install New Software" in the Help Menu and click the "add" button with this URL http://download.eclipse.org/tools/pdt/updates/latest/ that should show the latest release of PHP Development Tools (PDT). You might need to search for "php" or "pdt". For Nightly releases you can use http://download.eclipse.org/tools/pdt/updates/latest-nightly/.

I wanted to match a string that ends with ".*" For this I had to use the following:

"^.*\\.\\*$"

Kinda silly if you think about it :D Heres what it means. At the start of the string there can be any character zero or more times followed by a dot "." followed by a star (*) at the end of the string.

I hope this comes in handy for someone. Thanks for the backslash thing to Fabian.

Judging from everything you've said, it seems like the original Odómetro string you're dealing with is encoded with ISO 8859-1, not UTF-8.

Here's why I think so:

• json_encode produced parseable output after you ran the input string through utf8_encode, which converts from ISO 8859-1 to UTF-8.
• You did say that you got "mangled" output when using print_r after doing utf8_encode, but the mangled output you got is actually exactly what would happen by trying to parse UTF-8 text as ISO 8859-1 (ó is \x63\xb3 in UTF-8, but that sequence is ó in ISO 8859-1.
• Your htmlentities hackaround solution worked. htmlentities needs to know what the encoding of the input string to work correctly. If you don't specify one, it assumes ISO 8859-1. (html_entity_decode, confusingly, defaults to UTF-8, so your method had the effect of converting from ISO 8859-1 to UTF-8.)
• You said you had the same problem in Python, which would seem to exclude PHP from being the issue.

PHP will use the \uXXXX escaping, but as you noted, this is valid JSON.

So, it seems like you need to configure your connection to Postgres so that it will give you UTF-8 strings. The PHP manual indicates you'd do this by appending options='--client_encoding=UTF8' to the connection string. There's also the possibility that the data currently stored in the database is in the wrong encoding. (You could simply use utf8_encode, but this will only support characters that are part of ISO 8859-1).

Finally, as another answer noted, you do need to make sure that you're declaring the proper charset, with an HTTP header or otherwise (of course, this particular issue might have just been an artifact of the environment where you did your print_r testing).

Another "finally" block emulation using C++11 lambda functions

template <typename TCode, typename TFinallyCode>
inline void with_finally(const TCode &code, const TFinallyCode &finally_code)
{
    try
    {
        code();
    }
    catch (...)
    {
        try
        {
            finally_code();
        }
        catch (...) // Maybe stupid check that finally_code mustn't throw.
        {
            std::terminate();
        }
        throw;
    }
    finally_code();
}

Let's hope the compiler will optimize the code above.

Now we can write code like this:

with_finally(
    [&]()
    {
        try
        {
            // Doing some stuff that may throw an exception
        }
        catch (const exception1 &)
        {
            // Handling first class of exceptions
        }
        catch (const exception2 &)
        {
            // Handling another class of exceptions
        }
        // Some classes of exceptions can be still unhandled
    },
    [&]() // finally
    {
        // This code will be executed in all three cases:
        //   1) exception was not thrown at all
        //   2) exception was handled by one of the "catch" blocks above
        //   3) exception was not handled by any of the "catch" block above
    }
);

If you wish you can wrap this idiom into "try - finally" macros:

// Please never throw exception below. It is needed to avoid a compilation error
// in the case when we use "begin_try ... finally" without any "catch" block.
class never_thrown_exception {};

#define begin_try    with_finally([&](){ try
#define finally      catch(never_thrown_exception){throw;} },[&]()
#define end_try      ) // sorry for "pascalish" style :(

Now "finally" block is available in C++11:

begin_try
{
    // A code that may throw
}
catch (const some_exception &)
{
    // Handling some exceptions
}
finally
{
    // A code that is always executed
}
end_try; // Sorry again for this ugly thing

Personally I don't like the "macro" version of "finally" idiom and would prefer to use pure "with_finally" function even though a syntax is more bulky in that case.

You can test the code above here: http://coliru.stacked-crooked.com/a/1d88f64cb27b3813

PS

If you need a finally block in your code, then scoped guards or ON_FINALLY/ON_EXCEPTION macros will probably better fit your needs.

Here is short example of usage ON_FINALLY/ON_EXCEPTION:

void function(std::vector<const char*> &vector)
{
    int *arr1 = (int*)malloc(800*sizeof(int));
    if (!arr1) { throw "cannot malloc arr1"; }
    ON_FINALLY({ free(arr1); });

    int *arr2 = (int*)malloc(900*sizeof(int));
    if (!arr2) { throw "cannot malloc arr2"; }
    ON_FINALLY({ free(arr2); });

    vector.push_back("good");
    ON_EXCEPTION({ vector.pop_back(); });

    ...

A simple rule for us to remember what to use in which case:

• [S]ingle quotes are for [S]trings ; [D]ouble quotes are for [D]atabase identifiers;

In MySQL and MariaDB, the ` (backtick) symbol is the same as the " symbol. You can use " when your SQL_MODE has ANSI_QUOTES enabled.

Sometimes it can make the assignment of a bool value easier to read at first glance:

// With
button.IsEnabled = someControl.HasError ? false : true;

// Without
button.IsEnabled = !someControl.HasError;

brbcoding have been able to help me with the appropriate coding i needed, here is it

HTML

<input type="checkbox" id="checkme"/>
  <input type="submit" name="sendNewSms" class="inputButton" disabled="disabled" id="sendNewSms" value=" Send " />

Javascript

 var checker = document.getElementById('checkme');
 var sendbtn = document.getElementById('sendNewSms');
 // when unchecked or checked, run the function
 checker.onchange = function(){
if(this.checked){
    sendbtn.disabled = false;
} else {
    sendbtn.disabled = true;
}

}

result_array() returns Associative Array type data. Returning pure array is slightly faster than returning an array of objects. result() is recursive in that it returns an std class object where as result_array() just returns a pure array, so result_array() would be choice regarding performance.

You're looking for the --data-binary argument:

curl -i -X POST host:port/post-file \
  -H "Content-Type: text/xml" \
  --data-binary "@path/to/file"

In the example above, -i prints out all the headers so that you can see what's going on, and -X POST makes it explicit that this is a post. Both of these can be safely omitted without changing the behaviour on the wire. The path to the file needs to be preceded by an @ symbol, so curl knows to read from a file.

The facebook acess token looks similar too "1249203702|2.h1MTNeLqcLqw__.86400.129394400-605430316|-WE1iH_CV-afTgyhDPc"

2.h1MTNeLqcLqw__.86400.129394400-605430316

then split again by -

the last part 605430316 is the user id.

Here is the C# code to extract the user id from the access token:

   public long ParseUserIdFromAccessToken(string accessToken)
   {
        Contract.Requires(!string.isNullOrEmpty(accessToken);

        /*
         * access_token:
         *   1249203702|2.h1MTNeLqcLqw__.86400.129394400-605430316|-WE1iH_CV-afTgyhDPc
         *                                               |_______|
         *                                                   |
         *                                                user id
         */

        long userId = 0;

        var accessTokenParts = accessToken.Split('|');

        if (accessTokenParts.Length == 3)
        {
            var idPart = accessTokenParts[1];
            if (!string.IsNullOrEmpty(idPart))
            {
                var index = idPart.LastIndexOf('-');
                if (index >= 0)
                {
                    string id = idPart.Substring(index + 1);
                    if (!string.IsNullOrEmpty(id))
                    {
                        return id;
                    }
                }
            }
        }

        return null;
    }

WARNING: The structure of the access token is undocumented and may not always fit the pattern above. Use it at your own risk.

Update Due to changes in Facebook. the preferred method to get userid from the encrypted access token is as follows:

try
{
    var fb = new FacebookClient(accessToken);
    var result = (IDictionary<string, object>)fb.Get("/me?fields=id");
    return (string)result["id"];
}
catch (FacebookOAuthException)
{
    return null;
}

Notice the cool thing in S.Lott's comment - you can also call functions with *mylist and **mydict to unpack positional and keyword arguments:

def foo(a, b, c, d):
  print a, b, c, d

l = [0, 1]
d = {"d":3, "c":2}

foo(*l, **d)

Will print: 0 1 2 3

I don't think there is another way other than assigning value to that particular index of that array.

Try this out:

sudo ldconfig

sudo nano /etc/ld.so.conf.d/opencv.conf

and add this following line in the opencv.conf not in the command window

/usr/local/lib

Then:

sudo ldconfig

sudo nano /etc/bash.bashrc

and add this two lines in the bash.bashrc not in the command window

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig       
export PKG_CONFIG_PATH

at last reboot your Pi sudo reboot now

and try import cv2

You could use an fstream and open it with the std::ios::app flag. Have a look at the code below and it should clear your head.

...
fstream f("filename.ext", f.out | f.app);
f << "any";
f << "text";
f << "written";
f << "wll";
f << "be append";
...

You can find more information about the open modes here and about fstreams here.

Windows 10 Solution:

For me this issue was due to downloading and creating an AVD using Android Studio and then trying to use that virtual device with the Ionic command line. I resolved this by deleting all existing emulators and creating a new one from the command line.

(the avdmanager file typically lives in C:\Users\\Android\sdk\tools\bin)

List existing emulators: avdmanager list avd

Delete an existing emulator: avdmanager delete avd -n emulator_name

Add system image: sdkmanager "system-images;android-24;default;x86_64"

Create new emulator: sdkmanager "system-images;android-27;google_apis_playstore;x86"

Model.uniq.pluck(:rating)

# SELECT DISTINCT "models"."rating" FROM "models"

This has the advantages of not using sql strings and not instantiating models

HttpUtility.HtmlEncode / Decode
HttpUtility.UrlEncode / Decode

You can add a reference to the System.Web assembly if it's not available in your project

What you could do is use the 'style' attribute to add the background image to the element, that way you will still be calling the image in the HTML but you will still be able to use the background-size: cover css behaviour:

HTML:

    <div class="image-div" style="background-image:url(yourimage.jpg)">
    </div>

CSS:

    .image-div{
    background-size: cover;
    }

This is how I add the background-size: cover behaviour to elements that I need to dynamically load into HTML. You can then use awesome css classes like background-position: center. boom

File type handling is new with iPhone OS 3.2, and is different than the already-existing custom URL schemes. You can register your application to handle particular document types, and any application that uses a document controller can hand off processing of these documents to your own application.

For example, my application Molecules (for which the source code is available) handles the .pdb and .pdb.gz file types, if received via email or in another supported application.

To register support, you will need to have something like the following in your Info.plist:

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeIconFiles</key>
        <array>
            <string>Document-molecules-320.png</string>
            <string>Document-molecules-64.png</string>
        </array>
        <key>CFBundleTypeName</key>
        <string>Molecules Structure File</string>
        <key>CFBundleTypeRole</key>
        <string>Viewer</string>
        <key>LSHandlerRank</key>
        <string>Owner</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>com.sunsetlakesoftware.molecules.pdb</string>
            <string>org.gnu.gnu-zip-archive</string>
        </array>
    </dict>
</array>

Two images are provided that will be used as icons for the supported types in Mail and other applications capable of showing documents. The LSItemContentTypes key lets you provide an array of Uniform Type Identifiers (UTIs) that your application can open. For a list of system-defined UTIs, see Apple's Uniform Type Identifiers Reference. Even more detail on UTIs can be found in Apple's Uniform Type Identifiers Overview. Those guides reside in the Mac developer center, because this capability has been ported across from the Mac.

One of the UTIs used in the above example was system-defined, but the other was an application-specific UTI. The application-specific UTI will need to be exported so that other applications on the system can be made aware of it. To do this, you would add a section to your Info.plist like the following:

<key>UTExportedTypeDeclarations</key>
<array>
    <dict>
        <key>UTTypeConformsTo</key>
        <array>
            <string>public.plain-text</string>
            <string>public.text</string>
        </array>
        <key>UTTypeDescription</key>
        <string>Molecules Structure File</string>
        <key>UTTypeIdentifier</key>
        <string>com.sunsetlakesoftware.molecules.pdb</string>
        <key>UTTypeTagSpecification</key>
        <dict>
            <key>public.filename-extension</key>
            <string>pdb</string>
            <key>public.mime-type</key>
            <string>chemical/x-pdb</string>
        </dict>
    </dict>
</array>

This particular example exports the com.sunsetlakesoftware.molecules.pdb UTI with the .pdb file extension, corresponding to the MIME type chemical/x-pdb.

With this in place, your application will be able to handle documents attached to emails or from other applications on the system. In Mail, you can tap-and-hold to bring up a list of applications that can open a particular attachment.

When the attachment is opened, your application will be started and you will need to handle the processing of this file in your -application:didFinishLaunchingWithOptions: application delegate method. It appears that files loaded in this manner from Mail are copied into your application's Documents directory under a subdirectory corresponding to what email box they arrived in. You can get the URL for this file within the application delegate method using code like the following:

NSURL *url = (NSURL *)[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey];

Note that this is the same approach we used for handling custom URL schemes. You can separate the file URLs from others by using code like the following:

if ([url isFileURL])
{
    // Handle file being passed in
}
else
{
    // Handle custom URL scheme
}

Here's one I wrote... uses arcs instead of quadratic curves for better control over radius. Also, it leaves the stroking and filling up to you

    /* Canvas 2d context - roundRect
 *
 * Accepts 5 parameters, the start_x and start_y points, the end_x and end_y points, and the radius of the corners
 * 
 * No return value
 */

CanvasRenderingContext2D.prototype.roundRect = function(sx,sy,ex,ey,r) {
    var r2d = Math.PI/180;
    if( ( ex - sx ) - ( 2 * r ) < 0 ) { r = ( ( ex - sx ) / 2 ); } //ensure that the radius isn't too large for x
    if( ( ey - sy ) - ( 2 * r ) < 0 ) { r = ( ( ey - sy ) / 2 ); } //ensure that the radius isn't too large for y
    this.beginPath();
    this.moveTo(sx+r,sy);
    this.lineTo(ex-r,sy);
    this.arc(ex-r,sy+r,r,r2d*270,r2d*360,false);
    this.lineTo(ex,ey-r);
    this.arc(ex-r,ey-r,r,r2d*0,r2d*90,false);
    this.lineTo(sx+r,ey);
    this.arc(sx+r,ey-r,r,r2d*90,r2d*180,false);
    this.lineTo(sx,sy+r);
    this.arc(sx+r,sy+r,r,r2d*180,r2d*270,false);
    this.closePath();
}

Here is an example:

var _e = document.getElementById('#my_canvas');
var _cxt = _e.getContext("2d");
_cxt.roundRect(35,10,260,120,20);
_cxt.strokeStyle = "#000";
_cxt.stroke();

You can go to /etc/init.d/ - you will see a daemon template called skeleton.

You can duplicate it and then enter your script under the start function.

We are able to swap var like this :

var val1 =  117,
    val2 = 327;

val2 = val1-val2; 
console.log(val2);
val1 = val1-val2;
console.log(val1);
val2 = val1+val2;
console.log(val2);

Here is something that might help you doing it. I managed to do it in two iterations.

 private static IEnumerable<string> GetAllNonEmptyDirectories(string path)
   {
     var directories =
        Directory.EnumerateDirectories(path, "*.*", SearchOption.AllDirectories)
        .ToList();

     var directoryList = 
     (from directory in directories
     let isEmpty = Directory.GetFiles(directory, "*.*", SearchOption.AllDirectories).Length == 0
     where !isEmpty select directory)
     .ToList();

     return directoryList.ToList();
   }

You don't need a counter for back presses.

Just store a reference to the toast that is shown:

private Toast backtoast;

Then,

public void onBackPressed() {
    if(USER_IS_GOING_TO_EXIT) {
        if(backtoast!=null&&backtoast.getView().getWindowToken()!=null) {
            finish();
        } else {
            backtoast = Toast.makeText(this, "Press back to exit", Toast.LENGTH_SHORT);
            backtoast.show();
        }
    } else {
        //other stuff...
        super.onBackPressed();
    }
}

This will call finish() if you press back while the toast is still visible, and only if the back press would result in exiting the application.

You are mixing implicit joins with explicit joins. That is allowed, but you need to be aware of how to do that properly.

The thing is, explicit joins (the ones that are implemented using the JOIN keyword) take precedence over implicit ones (the 'comma' joins, where the join condition is specified in the WHERE clause).

Here's an outline of your query:

SELECT
  …
FROM a, b LEFT JOIN dkcd ON …
WHERE …

You are probably expecting it to behave like this:

SELECT
  …
FROM (a, b) LEFT JOIN dkcd ON …
WHERE …

that is, the combination of tables a and b is joined with the table dkcd. In fact, what's happening is

SELECT
  …
FROM a, (b LEFT JOIN dkcd ON …)
WHERE …

that is, as you may already have understood, dkcd is joined specifically against b and only b, then the result of the join is combined with a and filtered further with the WHERE clause. In this case, any reference to a in the ON clause is invalid, a is unknown at that point. That is why you are getting the error message.

If I were you, I would probably try to rewrite this query, and one possible solution might be:

SELECT DISTINCT
  a.maxa,
  b.mahuyen,
  a.tenxa,
  b.tenhuyen,
  ISNULL(dkcd.tong, 0) AS tongdkcd
FROM phuongxa a
  INNER JOIN quanhuyen b ON LEFT(a.maxa, 2) = b.mahuyen
  LEFT OUTER JOIN (
    SELECT
      maxa,
      COUNT(*) AS tong
    FROM khaosat
    WHERE CONVERT(datetime, ngaylap, 103) BETWEEN 'Sep 1 2011' AND 'Sep 5 2011'
    GROUP BY maxa
  ) AS dkcd ON dkcd.maxa = a.maxa
WHERE a.maxa <> '99'
ORDER BY a.maxa

Here the tables a and b are joined first, then the result is joined to dkcd. Basically, this is the same query as yours, only using a different syntax for one of the joins, which makes a great difference: the reference a.maxa in the dkcd's join condition is now absolutely valid.

As @Aaron Bertrand has correctly noted, you should probably qualify maxa with a specific alias, probably a, in the ORDER BY clause.

I had the same problem when my plugin was depending on another project, which exported some packages in its manifest file. Instead of changing access rules, I have managed to solve the problem by adding the required packages into its Export-Package section. This makes the packages legally visible. Eclipse actually provides this fix on the "Access restriction" error marker.

You will need to define the repository outside of buildscript. The buildscript configuration block only sets up the repositories and dependencies for the classpath of your build script but not your application.

If your column is of type DATE (as you say), then you don't need to convert it into a string first (in fact you would convert it implicitly to a string first, then explicitly to a date and again explicitly to a string):

SELECT TO_CHAR(COL1, 'mm/dd/yyyy') FROM TABLE1

The date format your seeing for your column is an artifact of the tool your using (TOAD, SQL Developer etc.) and it's language settings.

This query will get you all the tables in the database

USE [DatabaseName];

SELECT * FROM information_schema.tables;

You don't. The closest thing you can do is working with Maps to simulate it, or defining your own Objects to deal with.

Get gcc for Windows . However, you will have to install MinGW as well.

You can use Visual Studio 2010 express edition as well. Link here

It can also be used as below:

from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)

I use SQLYog at home and work. It turns out they DO have a free open-source version, though sadly they've been trying to hide that fact for the last few years.

You can download the open-source version from https://github.com/webyog/sqlyog-community - just click the "Download SQLyog Community Version" link.

You should use <h:panelGroup ...> tag with attribute rendered. If you set true to rendered, the content of <h:panelGroup ...> won't be shown. Your XHTML file should have something like this:

<h:panelGroup rendered="#{userBean.showPassword}">
    <h:outputText id="password" value="#{userBean.password}"/>
</h:panelGroup>

UserBean.java:

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
@ManagedBean
@SessionScoped
public class UserBean implements Serializable{
    private boolean showPassword = false;
    private String password = "";

    public boolean isShowPassword(){
        return showPassword;
    }
    public void setPassword(password){
        this.password = password;
    }
    public String getPassword(){
        return this.password;
    }
}

Using of fgrep or adding -F option to grep could help. But for faster calculations you could use Awk.

You could try one of these Awk methods:

I didn't know you could do that with cp.

You can do it with mkdir ..

mkdir -p /var/path/to/your/dir

EDIT See lhunath's answer for incorporating cp.

After hours of searching and trying I found out that on a x64 server the MSOnline modules must be installed for x64, and some programs that need to run them are using the x86 PS version, so they will never find it.

[SOLUTION] What I did to solve the issue was:

Copy the folders called MSOnline and MSOnline Extended from the source

C:\Windows\System32\WindowsPowerShell\v1.0\Modules\

to the folder

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Modules\

And then in PS run the Import-Module MSOnline, and it will automatically get the module :D

Keep it simple!

An AsyncTask is background task which runs in the background thread. It takes an Input, performs Progress and gives Output.

ie AsyncTask<Input,Progress,Output>.

In my opinion the main source of confusion comes when we try to memorize the parameters in the AsyncTask.
The key is Don't memorize.
If you can visualize what your task really needs to do then writing the AsyncTask with the correct signature would be a piece of cake.
Just figure out what your Input, Progress and Output are and you will be good to go.

For example:

Heart of the AsyncTask!

doInBackgound() method is the most important method in an AsyncTask because

• Only this method runs in the background thread and publish data to UI thread.
• Its signature changes with the AsyncTask parameters.

So lets see the relationship

doInBackground() and onPostExecute(),onProgressUpdate() are also related

Show me the code
So how will I write the code for DownloadTask?

DownloadTask extends AsyncTask<String,Integer,String>{

      @Override
      public void onPreExecute()
      {}

      @Override
      public String doInbackGround(String... params)
      {
               // Download code
               int downloadPerc = // calculate that
               publish(downloadPerc);

               return "Download Success";
      }

      @Override
      public void onPostExecute(String result)
      {
          super.onPostExecute(result);
      }

      @Override
      public void onProgressUpdate(Integer... params)
      {
             // show in spinner, access UI elements
      }

}

How will you run this Task

new DownLoadTask().execute("Paradise.mp3");

You can use:

getResources().getColor(R.color.idname);

Check here on how to define custom colors:

http://sree.cc/google/android/defining-custom-colors-using-xml-in-android

EDIT(1): Since getColor(int id) is deprecated now, this must be used :

ContextCompat.getColor(context, R.color.your_color);

(added in support library 23)

EDIT(2):

Below code can be used for both pre and post Marshmallow (API 23)

ResourcesCompat.getColor(getResources(), R.color.your_color, null); //without theme

ResourcesCompat.getColor(getResources(), R.color.your_color, your_theme); //with theme

I needed a multilevel dropdown menu in css. I couldn't find an error-free menu that I searched. Then I created a menu instance using the Css hover transition effect.I hope it will be useful for users.

On Linux I also notice that :

Interruption of system calls and library functions by signal handlers
If a signal handler is invoked while a system call or library function call is blocked, then either:

• the call is automatically restarted after the signal handler returns; or

• the call fails with the error EINTR.

... The details vary across UNIX systems; below, the details for Linux.

If a blocked call to one of the following interfaces is interrupted by a signal handler, then the call is automatically restarted after the signal handler returns if the SA_RESTART flag was used; otherwise the call fails with the error EINTR:

• read(2), readv(2), write(2), writev(2), and ioctl(2) calls on "slow" devices.

.....

The following interfaces are never restarted after being interrupted by a signal handler, regardless of the use of SA_RESTART; they always fail with the error EINTR when interrupted by a signal handler:

• "Input" socket interfaces, when a timeout (SO_RCVTIMEO) has been set on the socket using setsockopt(2): accept(2), recv(2), recvfrom(2), recvmmsg(2) (also with a non-NULL timeout argument), and recvmsg(2).

• "Output" socket interfaces, when a timeout (SO_RCVTIMEO) has been set on the socket using setsockopt(2): connect(2), send(2), sendto(2), and sendmsg(2).

Check man 7 signal for more details.

A simple usage would be use signal to avoid recvfrom blocking indefinitely.

An example from APUE:

#include "apue.h"
#include <netdb.h>
#include <errno.h>
#include <sys/socket.h>

#define BUFLEN      128
#define TIMEOUT     20

void
sigalrm(int signo)
{
}

void
print_uptime(int sockfd, struct addrinfo *aip)
{
    int     n;
    char    buf[BUFLEN];

    buf[0] = 0;
    if (sendto(sockfd, buf, 1, 0, aip->ai_addr, aip->ai_addrlen) < 0)

I was running an older server where I couldn't run install-module because the PowerShell version was 4.0. You can check the PowerShell version using the PowerShell command line

ps>HOST . 

https://gallery.technet.microsoft.com/office/PowerShell-Install-Module-388e47a1

Use this link to download necessary updates. Check to see if your Windows version needs the update.

document.getElementById('id1').bgColor = '#00FF00';

seems to work. I don't think .style.backgroundColor does.

Just so my fellow neuronically impaired comrades might chance upon it here, I had assumed that, for web projects, if the linked file was an external .config file that the "output directory" would be the same directory that web.config lives in, i.e. your web project's root. In retrospect, it is entirely unsurprising that it copies the linked file into the root/bin folder.

So, if it's an appSettings include file, your web.config's open tag would be

<appSettings file=".\bin\includedAppSettingsFile.config">

Duh.

a = ["some", "thing"]
b = ["another", "thing"]

To append b to a and store the result in a:

a.push(*b)

or

a += b

In either case, a becomes:

["some", "thing", "another", "thing"]

but in the former case, the elements of b are appended to the existing a array, and in the latter case the two arrays are concatenated together and the result is stored in a.

One other thing. You may need to specify the -L option as well - eg

-Wl,-rpath,/path/to/foo -L/path/to/foo -lbaz

or you may end up with an error like

ld: cannot find -lbaz

Are the Android samples not good enough? I've found the ApiDemos to be indispensable when learning a new aspect of Android, myself.

Based largely off of @mklement0's excellent, and chock-full of random, useful bashisms - as well as other answers to this / other questions / "that darn internet"... I wrapped it all up in a little, slightly more comprehensible, reusable function for my (or your) .bash_profile that takes care of what (I consider) should be a more robust version of dirname/basename / what have you..

function path { SAVEIFS=$IFS; IFS=""   # stash IFS for safe-keeping, etc.
    [[ $# != 2 ]] && echo "usage: path <path> <dir|name|fullname|ext>" && return    # demand 2 arguments
    [[ $1 =~ ^(.*/)?(.+)?$ ]] && {     # regex parse the path
        dir=${BASH_REMATCH[1]}
        file=${BASH_REMATCH[2]}
        ext=$([[ $file = *.* ]] && printf %s ${file##*.} || printf '')
        # edge cases for extensionless files and files like ".nesh_profile.coffee"
        [[ $file == $ext ]] && fnr=$file && ext='' || fnr=${file:0:$((${#file}-${#ext}))}
        case "$2" in
             dir) echo      "${dir%/*}"; ;;
            name) echo      "${fnr%.*}"; ;;
        fullname) echo "${fnr%.*}.$ext"; ;;
             ext) echo           "$ext"; ;;
        esac
    }
    IFS=$SAVEIFS
}     

Usage examples...

SOMEPATH=/path/to.some/.random\ file.gzip
path $SOMEPATH dir        # /path/to.some
path $SOMEPATH name       # .random file
path $SOMEPATH ext        # gzip
path $SOMEPATH fullname   # .random file.gzip                     
path gobbledygook         # usage: -bash <path> <dir|name|fullname|ext>

Probably you can implement generic static lookup method.

Like so

public class LookupUtil {
   public static <E extends Enum<E>> E lookup(Class<E> e, String id) {   
      try {          
         E result = Enum.valueOf(e, id);
      } catch (IllegalArgumentException e) {
         // log error or something here

         throw new RuntimeException(
           "Invalid value for enum " + e.getSimpleName() + ": " + id);
      }

      return result;
   }
}

Then you can

public enum MyEnum {
   static public MyEnum lookup(String id) {
       return LookupUtil.lookup(MyEnum.class, id);
   }
}

or call explicitly utility class lookup method.

Arrow functions => best ES6 feature so far. They are a tremendously powerful addition to ES6, that I use constantly.

Wait, you can't use arrow function everywhere in your code, its not going to work in all cases like this where arrow functions are not usable. Without a doubt, the arrow function is a great addition it brings code simplicity.

But you can’t use an arrow function when a dynamic context is required: defining methods, create objects with constructors, get the target from this when handling events.

Arrow functions should NOT be used because:

1. They do not have this

   It uses “lexical scoping” to figure out what the value of “this” should be. In simple word lexical scoping it uses “this” from the inside the function’s body.

2. They do not have arguments

   Arrow functions don’t have an arguments object. But the same functionality can be achieved using rest parameters.

   let sum = (...args) => args.reduce((x, y) => x + y, 0) sum(3, 3, 1) // output - 7 `

3. They cannot be used with new

   Arrow functions can't be construtors because they do not have a prototype property.

When to use arrow function and when not:

1. Don't use to add function as a property in object literal because we can not access this.
2. Function expressions are best for object methods. Arrow functions are best for callbacks or methods like map, reduce, or forEach.
3. Use function declarations for functions you’d call by name (because they’re hoisted).
4. Use arrow functions for callbacks (because they tend to be terser).

Have you tried using a icon font like http://fortawesome.github.io/Font-Awesome/

Bootstrap comes with their own library, but it doesn't have as many icons as Font Awesome.

The above command will add the package to the node modules and update the package.json file

This is a simple tutorial on creating csv files using C# that you will be able to edit and expand on to fit your own needs.

First you’ll need to create a new Visual Studio C# console application, there are steps to follow to do this.

The example code will create a csv file called MyTest.csv in the location you specify. The contents of the file should be 3 named columns with text in the first 3 rows.

https://tidbytez.com/2018/02/06/how-to-create-a-csv-file-with-c/

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;

namespace CreateCsv
{
    class Program
    {
        static void Main()
        {
            // Set the path and filename variable "path", filename being MyTest.csv in this example.
            // Change SomeGuy for your username.
            string path = @"C:\Users\SomeGuy\Desktop\MyTest.csv";

            // Set the variable "delimiter" to ", ".
            string delimiter = ", ";

            // This text is added only once to the file.
            if (!File.Exists(path))
            {
                // Create a file to write to.
                string createText = "Column 1 Name" + delimiter + "Column 2 Name" + delimiter + "Column 3 Name" + delimiter + Environment.NewLine;
                File.WriteAllText(path, createText);
            }

            // This text is always added, making the file longer over time
            // if it is not deleted.
            string appendText = "This is text for Column 1" + delimiter + "This is text for Column 2" + delimiter + "This is text for Column 3" + delimiter + Environment.NewLine;
            File.AppendAllText(path, appendText);

            // Open the file to read from.
            string readText = File.ReadAllText(path);
            Console.WriteLine(readText);
        }
    }
}

I solved this by Following steps:

1. Uninstalled python
2. removed Python37 Folder from C/program files/ and user/sukhendra/AppData
3. removed all python37 paths

then only Anaconda is remaining in my PC so opened Anaconda and then it's all working fine for me

Python 2.5+:

python --version

Python 2.4-:

python -c 'import sys; print(sys.version)'

You should first make sure that the process has completed running and the return code has been read out using the .wait method. This will return the code. If you want access to it later, it's stored as .returncode in the Popen object.

use the command prompt, as suggested. I figured out why explorer is so slow a while ago, it gives you an estimate of how long it will take to delete the files/folders. To do this, it has to scan the number of items and the size. This takes ages, hence the ridiculous wait with large folders.

Also, explorer will stop if there is a particular problem with a file,

Here's an alternative solution to this question. My adapter:

    private class PagerAdapter extends FragmentPagerAdapter implements 
                    ViewPager.OnPageChangeListener, TabListener {

    private List<Fragment> mFragments = new ArrayList<Fragment>();
    private ViewPager mPager;
    private ActionBar mActionBar;

    private Fragment mPrimaryItem;

    public PagerAdapter(FragmentManager fm, ViewPager vp, ActionBar ab) {
        super(fm);
        mPager = vp;
        mPager.setAdapter(this);
        mPager.setOnPageChangeListener(this);
        mActionBar = ab;
    }

    public void addTab(PartListFragment frag) {
        mFragments.add(frag);
        mActionBar.addTab(mActionBar.newTab().setTabListener(this).
                            setText(frag.getPartCategory()));
    }

    @Override
    public Fragment getItem(int position) {
        return mFragments.get(position);
    }

    @Override
    public int getCount() {
        return mFragments.size();
    }

    /** (non-Javadoc)
     * @see android.support.v4.app.FragmentStatePagerAdapter#setPrimaryItem(android.view.ViewGroup, int, java.lang.Object)
     */
    @Override
    public void setPrimaryItem(ViewGroup container, int position,
            Object object) {
        super.setPrimaryItem(container, position, object);
        mPrimaryItem = (Fragment) object;
    }

    /** (non-Javadoc)
     * @see android.support.v4.view.PagerAdapter#getItemPosition(java.lang.Object)
     */
    @Override
    public int getItemPosition(Object object) {
        if (object == mPrimaryItem) {
            return POSITION_UNCHANGED;
        }
        return POSITION_NONE;
    }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        mPager.setCurrentItem(tab.getPosition());
    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction ft) { }

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction ft) { }

    @Override
    public void onPageScrollStateChanged(int arg0) { }

    @Override
    public void onPageScrolled(int arg0, float arg1, int arg2) { }

    @Override
    public void onPageSelected(int position) {
        mActionBar.setSelectedNavigationItem(position);
    }

    /**
     * This method removes the pages from ViewPager
     */
    public void removePages() {
        mActionBar.removeAllTabs();

                    //call to ViewPage to remove the pages
        vp.removeAllViews();
        mFragments.clear();

        //make this to update the pager
        vp.setAdapter(null);
        vp.setAdapter(pagerAdapter);
    }
}

Code to remove and add dynamically

//remove the pages. basically call to method removeAllViews from `ViewPager`
pagerAdapter.removePages();

pagerAdapter.addPage(pass your fragment);

After the advice of Peri Hartman, it started to work after I set null do ViewPager adapter and put the adapter again after the views removed. Before this the page 0 doesnt showed its list contents.

Thanks.

Each instantiation and full specialization of std::atomic<> represents a type that different threads can simultaneously operate on (their instances), without raising undefined behavior:

Objects of atomic types are the only C++ objects that are free from data races; that is, if one thread writes to an atomic object while another thread reads from it, the behavior is well-defined.

In addition, accesses to atomic objects may establish inter-thread synchronization and order non-atomic memory accesses as specified by std::memory_order.

std::atomic<> wraps operations that, in pre-C++ 11 times, had to be performed using (for example) interlocked functions with MSVC or atomic bultins in case of GCC.

Also, std::atomic<> gives you more control by allowing various memory orders that specify synchronization and ordering constraints. If you want to read more about C++ 11 atomics and memory model, these links may be useful:

• C++ atomics and memory ordering
• Comparison: Lockless programming with atomics in C++ 11 vs. mutex and RW-locks
• C++11 introduced a standardized memory model. What does it mean? And how is it going to affect C++ programming?
• Concurrency in C++11

Note that, for typical use cases, you would probably use overloaded arithmetic operators or another set of them:

std::atomic<long> value(0);
value++; //This is an atomic op
value += 5; //And so is this

Because operator syntax does not allow you to specify the memory order, these operations will be performed with std::memory_order_seq_cst, as this is the default order for all atomic operations in C++ 11. It guarantees sequential consistency (total global ordering) between all atomic operations.

In some cases, however, this may not be required (and nothing comes for free), so you may want to use more explicit form:

std::atomic<long> value {0};
value.fetch_add(1, std::memory_order_relaxed); // Atomic, but there are no synchronization or ordering constraints
value.fetch_add(5, std::memory_order_release); // Atomic, performs 'release' operation

Now, your example:

a = a + 12;

will not evaluate to a single atomic op: it will result in a.load() (which is atomic itself), then addition between this value and 12 and a.store() (also atomic) of final result. As I noted earlier, std::memory_order_seq_cst will be used here.

However, if you write a += 12, it will be an atomic operation (as I noted before) and is roughly equivalent to a.fetch_add(12, std::memory_order_seq_cst).

As for your comment:

A regular int has atomic loads and stores. Whats the point of wrapping it with atomic<>?

Your statement is only true for architectures that provide such guarantee of atomicity for stores and/or loads. There are architectures that do not do this. Also, it is usually required that operations must be performed on word-/dword-aligned address to be atomic std::atomic<> is something that is guaranteed to be atomic on every platform, without additional requirements. Moreover, it allows you to write code like this:

void* sharedData = nullptr;
std::atomic<int> ready_flag = 0;

// Thread 1
void produce()
{
    sharedData = generateData();
    ready_flag.store(1, std::memory_order_release);
}

// Thread 2
void consume()
{
    while (ready_flag.load(std::memory_order_acquire) == 0)
    {
        std::this_thread::yield();
    }

    assert(sharedData != nullptr); // will never trigger
    processData(sharedData);
}

Note that assertion condition will always be true (and thus, will never trigger), so you can always be sure that data is ready after while loop exits. That is because:

• store() to the flag is performed after sharedData is set (we assume that generateData() always returns something useful, in particular, never returns NULL) and uses std::memory_order_release order:

memory_order_release

A store operation with this memory order performs the release operation: no reads or writes in the current thread can be reordered after this store. All writes in the current thread are visible in other threads that acquire the same atomic variable

• sharedData is used after while loop exits, and thus after load() from flag will return a non-zero value. load() uses std::memory_order_acquire order:

std::memory_order_acquire

A load operation with this memory order performs the acquire operation on the affected memory location: no reads or writes in the current thread can be reordered before this load. All writes in other threads that release the same atomic variable are visible in the current thread.

This gives you precise control over the synchronization and allows you to explicitly specify how your code may/may not/will/will not behave. This would not be possible if only guarantee was the atomicity itself. Especially when it comes to very interesting sync models like the release-consume ordering.

Please take care that the epoch time is in second and Date object accepts Long value which is in milliseconds. Hence you would have to multiply epoch value with 1000 to use it as long value . Like below :-

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmss");
sdf.setTimeZone(TimeZone.getTimeZone(timeZone));
Long dateLong=Long.parseLong(sdf.format(epoch*1000));

If you didn't want to use async/await inside your method, but still "decorate" it so as to be able to use the await keyword from outside, TaskCompletionSource.cs:

public static Task<T> RunAsync<T>(Func<T> function)
{ 
    if (function == null) throw new ArgumentNullException(“function”); 
    var tcs = new TaskCompletionSource<T>(); 
    ThreadPool.QueueUserWorkItem(_ =>          
    { 
        try 
        {  
           T result = function(); 
           tcs.SetResult(result);  
        } 
        catch(Exception exc) { tcs.SetException(exc); } 
   }); 
   return tcs.Task; 
}

From here and here

To support such a paradigm with Tasks, we need a way to retain the Task façade and the ability to refer to an arbitrary asynchronous operation as a Task, but to control the lifetime of that Task according to the rules of the underlying infrastructure that’s providing the asynchrony, and to do so in a manner that doesn’t cost significantly. This is the purpose of TaskCompletionSource.

I saw it's also used in the .NET source, e.g. WebClient.cs:

    [HostProtection(ExternalThreading = true)]
    [ComVisible(false)]
    public Task<string> UploadStringTaskAsync(Uri address, string method, string data)
    {
        // Create the task to be returned
        var tcs = new TaskCompletionSource<string>(address);

        // Setup the callback event handler
        UploadStringCompletedEventHandler handler = null;
        handler = (sender, e) => HandleCompletion(tcs, e, (args) => args.Result, handler, (webClient, completion) => webClient.UploadStringCompleted -= completion);
        this.UploadStringCompleted += handler;

        // Start the async operation.
        try { this.UploadStringAsync(address, method, data, tcs); }
        catch
        {
            this.UploadStringCompleted -= handler;
            throw;
        }

        // Return the task that represents the async operation
        return tcs.Task;
    }

Finally, I also found the following useful:

I get asked this question all the time. The implication is that there must be some thread somewhere that’s blocking on the I/O call to the external resource. So, asynchronous code frees up the request thread, but only at the expense of another thread elsewhere in the system, right? No, not at all.

To understand why asynchronous requests scale, I’ll trace a (simplified) example of an asynchronous I/O call. Let’s say a request needs to write to a file. The request thread calls the asynchronous write method. WriteAsync is implemented by the Base Class Library (BCL), and uses completion ports for its asynchronous I/O. So, the WriteAsync call is passed down to the OS as an asynchronous file write. The OS then communicates with the driver stack, passing along the data to write in an I/O request packet (IRP).

This is where things get interesting: If a device driver can’t handle an IRP immediately, it must handle it asynchronously. So, the driver tells the disk to start writing and returns a “pending” response to the OS. The OS passes that “pending” response to the BCL, and the BCL returns an incomplete task to the request-handling code. The request-handling code awaits the task, which returns an incomplete task from that method and so on. Finally, the request-handling code ends up returning an incomplete task to ASP.NET, and the request thread is freed to return to the thread pool.

Introduction to Async/Await on ASP.NET

If the target is to improve scalability (rather than responsiveness), it all relies on the existence of an external I/O that provides the opportunity to do that.

In node V10, you can use the flag --experimental-modules to tell Nodejs you want to use import. But your entry script should end with .mjs.

Note this is still an experimental thing and should not be used in production.

// main.mjs
import utils from './utils.js'
utils.print();

// utils.js
module.exports={
    print:function(){console.log('print called')}
}

Are you sure you haven't missed a ; before/after the overflow-y: scroll?

I've just tested the following in IE7 and Firefox and it works fine

<!-- Scroll bar present but disabled when less content -->_x000D_
<div style="width: 200px; height: 100px; overflow-y: scroll;">_x000D_
  test_x000D_
</div>_x000D_

I had the same problem. Just open the project main folder. and then close and reopen the project sub folder app.

By the way, for any of you guys that just need to target Safari on mobiles, just add a media query to this hack:

@media screen and (max-width: 767px) {
    _::-webkit-full-page-media, _:future, :root .safari_only {
        padding: 10px; //or any property you need
    }
}

And don't forget to add the .safari_only class to the element you want to target, example:

<div class='safari_only'> This div will have a padding:10px in a mobile with Safari  </div>

Do you really want to style the <div>? Or do you want to style the <input type="button">? You should use the correct selector if you want the latter:

input[type=button] {
    color:#08233e;
    font:2.4em Futura, ‘Century Gothic’, AppleGothic, sans-serif;
    font-size:70%;
    /* ... other rules ... */
    cursor:pointer;
}

input[type=button]:hover {
    background-color:rgba(255,204,0,0.8);
}

Iterate through strings characters and use functions of 'Char' called 'IsLetter' and 'IsDigit'.

If you need something more specific - use Regex class.

Try System.getProperty( "line.separator" )

   writer.write(System.getProperty( "line.separator" ));

If your destination element is empty and will only contain the <svg> tag you could consider using ng-bind-html as follow :

Declare your HTML tag in the directive scope variable

link: function (scope, iElement, iAttrs) {

    scope.svgTag = '<svg width="600" height="100" class="svg"></svg>';

    ...
}

Then, in your directive template, just add the proper attribute at the exact place you want to append the svg tag :

<!-- start of directive template code -->
...
<!-- end of directive template code -->
<div ng-bind-html="svgTag"></div>

Don't forget to include ngSanitize to allow ng-bind-html to automatically parse the HTML string to trusted HTML and avoid insecure code injection warnings.

See official documentation for more details.

I was having same problem in my ubuntu. When I run command adb devices it shows me ?????????? No permission.

Then I tried with adb kill-server and then sudo su and adb devices. No need to run command adb start-server devices command will start it automatically if it is not already started.

Hope this will save once one's minutes.

This will return pure class name even when using namespace:

echo substr(strrchr(__CLASS__, "\\"), 1);    

no, you need to do something like:

$('input.sitebg').val('000000');

but you should really be using unique IDs if you can.

You can also get more specific, such as:

$('input[type=text].sitebg').val('000000');

EDIT:

do this to find your input based on the name attribute:

$('input[name=sitebg]').val('000000');

You could use the n-th child selector.

to target the nth element you could then use:

td:nth-child(n) {  
  /* your stuff here */
}

(where n starts at 1)

In the model, write the below code;

public $timestamps = false;

This would work.

Explanation : By default laravel will expect created_at & updated_at column in your table. By making it to false it will override the default setting.

Spent way too much time coming back to this page so just gonna leave this here:

File file = new ClassPathResource("data/data.json").getFile();

Since getJdbcTemplate().queryForMap expects minimum size of one but when it returns null it shows EmptyResultDataAccesso fix dis when can use below logic

Map<String, String> loginMap =null;
try{
    loginMap = getJdbcTemplate().queryForMap(sql, new Object[] {CustomerLogInInfo.getCustLogInEmail()});
}
catch(EmptyResultDataAccessException ex){
    System.out.println("Exception.......");
    loginMap =null;
}
if(loginMap==null || loginMap.isEmpty()){
    return null;
}
else{
    return loginMap;
}

You can use a middleware to set the default Content-Type, and set Content-Type differently for particular APIs. Here is an example:

const express = require('express');
const app = express();

const port = process.env.PORT || 3000;

const server = app.listen(port);

server.timeout = 1000 * 60 * 10; // 10 minutes

// Use middleware to set the default Content-Type
app.use(function (req, res, next) {
    res.header('Content-Type', 'application/json');
    next();
});

app.get('/api/endpoint1', (req, res) => {
    res.send(JSON.stringify({value: 1}));
})

app.get('/api/endpoint2', (req, res) => {
    // Set Content-Type differently for this particular API
    res.set({'Content-Type': 'application/xml'});
    res.send(`<note>
        <to>Tove</to>
        <from>Jani</from>
        <heading>Reminder</heading>
        <body>Don't forget me this weekend!</body>
        </note>`);
})

rem This is the command line version
cscript "C:\Users\guest\Desktop\123\MyScript.vbs"

OR

rem This is the windowed version
wscript "C:\Users\guest\Desktop\123\MyScript.vbs"

You can also add the option //e:vbscript to make sure the scripting engine will recognize your script as a vbscript.

Windows/DOS batch files doesn't require escaping \ like *nix.

You can still use "C:\Users\guest\Desktop\123\MyScript.vbs", but this requires the user has *.vbs associated to wscript.

Use the clip property along with opacity, z-index, absolute positioning, and some browser filters to place the file input over the desired button:

Try setting this before you print:

setvbuf (stdout, NULL, _IONBF, 0);

SELECT RIGHT('0' + CAST(sortexport_csv AS VARCHAR), 2)
FROM your_table

For a quick non-JQuery function...

function jsonToQueryString(json) {
    return '?' + 
        Object.keys(json).map(function(key) {
            return encodeURIComponent(key) + '=' +
                encodeURIComponent(json[key]);
        }).join('&');
}

Note this doesn't handle arrays or nested objects.

The correct options are (in increasing order of recommendation):

# Single POSIX test command with -o operator (not recommended anymore).
# Quotes strongly recommended to guard against empty or undefined variables.
while [ "$stats" -gt 300 -o "$stats" -eq 0 ]

# Two POSIX test commands joined in a list with ||.
# Quotes strongly recommended to guard against empty or undefined variables.
while [ "$stats" -gt 300 ] || [ "$stats" -eq 0 ]

# Two bash conditional expressions joined in a list with ||.
while [[ $stats -gt 300 ]] || [[ $stats -eq 0 ]]

# A single bash conditional expression with the || operator.
while [[ $stats -gt 300 || $stats -eq 0 ]]

# Two bash arithmetic expressions joined in a list with ||.
# $ optional, as a string can only be interpreted as a variable
while (( stats > 300 )) || (( stats == 0 ))

# And finally, a single bash arithmetic expression with the || operator.
# $ optional, as a string can only be interpreted as a variable
while (( stats > 300 || stats == 0 ))

Some notes:

1. Quoting the parameter expansions inside [[ ... ]] and ((...)) is optional; if the variable is not set, -gt and -eq will assume a value of 0.

2. Using $ is optional inside (( ... )), but using it can help avoid unintentional errors. If stats isn't set, then (( stats > 300 )) will assume stats == 0, but (( $stats > 300 )) will produce a syntax error.

I would use a listener. Fragment1 calling the listener (main activity)

If you are using ios 5.0 or later than please use this code

-(BOOL)isPresented
{
    if ([self isBeingPresented]) {
        // being presented
         return YES;
    } else if ([self isMovingToParentViewController]) {
        // being pushed
         return NO;
    } else {
        // simply showing again because another VC was dismissed
         return NO;
    }
}

SELECT col1,
  col2
FROM
  (SELECT rownum X,col_table1 FROM table1) T1
INNER JOIN
  (SELECT rownum Y, col_table2 FROM table2) T2
ON T1.X=T2.Y;

If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:

• Bootstrap Datetime Picker 1

• Bootstrap Datetime Picker 2

The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.

String temp = passwordSalt;
byte[] byteSalt = temp.getBytes();
int start = 32;
for (int i = 0; i < byteData.length; i ++)
{
    byteData[start + i] = byteSalt[i];
}

The problem with your code here is that the variable i that is being used to index the arrays is going past both the byteSalt array and the byteData array. So, Make sure that byteData is dimensioned to be at least the maximum length of the passwordSalt string plus 32. What will correct it is replacing the following line:

for (int i = 0; i < byteData.length; i ++)

with:

for (int i = 0; i < byteSalt.length; i ++)

Use:

li:hover {
    cursor: pointer;
}

Other valid values (which hand is not) for the current HTML specification can be viewed here.

I hope what you are trying to achieve is like this. For this please use Box layout.

A CTE worked for me:

with cte as (
  select 1 col1
  from temptable
  group by column_1
)

select COUNT(col1)
from cte;

Well you could use the <Directory> tag for example:

<Directory /inscription>
  <Files log.txt>
    Order allow,deny
    Deny from all
  </Files>
</Directory>

Do not use ./ because if you just use / it looks at the root directory of your site.

For a more detailed example visit http://httpd.apache.org/docs/2.2/sections.html

Use a list comprehension (this is the way to go in pure Python):

>>> l = [1, 2, 3, 4]
>>> [i**2 for i in l]
[1, 4, 9, 16]

Or numpy (a well-established module):

>>> numpy.array([1, 2, 3, 4])**2
array([ 1,  4,  9, 16])

In numpy, math operations on arrays are, by default, executed element-wise. That's why you can **2 an entire array there.

Other possible solutions would be map-based, but in this case I'd really go for the list comprehension. It's Pythonic :) and a map-based solution that requires lambdas is slower than LC.

I would use two classes. Keep your test class and add a second class called testhover which you only add to those you want to hover - alongside the test class. This isn't directly what you asked but without more context it feels like the best solution and is possibly the cleanest and simplest way of doing it.

Example:

.test {  border: 0px; }_x000D_
.testhover:hover {  border: 1px solid red; }

<div class="test"> blah </div>_x000D_
<div class="test"> blah </div>_x000D_
<div class="test testhover"> blah </div>

You can add position: fixed; with top left right bottom 0 attribute, that solution work on older browsers too.

If you want to embed it, add position: absolute; to the wrapper, and position: relative to the div outside of the wrapper.

.wrapper {_x000D_
  position: fixed;_x000D_
  top: 0;_x000D_

You could also use zip

import matplotlib.pyplot as plt

l = [(0, 6.0705199999997801e-08), (1, 2.1015700100300739e-08),
     (2, 7.6280656623374823e-09), (3, 5.7348209304555086e-09),
     (4, 3.6812203579604238e-09), (5, 4.1572516753310418e-09)]

x, y = zip(*l)

plt.plot(x, y)

Web page automation ? Definitely "webbot"

webbot even works web pages which have dynamically changing id and classnames and has more methods and features than selenium or mechanize.

Here's a snippet :)

from webbot import Browser 
web = Browser()
web.go_to('google.com') 
web.click('Sign in')
web.type('[email protected]' , into='Email')
web.click('NEXT' , tag='span')
web.type('mypassword' , into='Password' , id='passwordFieldId') # specific selection
web.click('NEXT' , tag='span') # you are logged in ^_^

The docs are also pretty straight forward and simple to use : https://webbot.readthedocs.io

 $('elements-to-match').click(function(){
        alert("The id is "+ this.id );
    });

no need to wrap it in a jquery object

You can also Try This

-- DECLARE field because your table type may be text
DECLARE @mmRxClaim nvarchar(MAX) 

-- Getting Value from table
SELECT top (1) @mmRxClaim = mRxClaim FROM RxClaim WHERE rxclaimid_PK =362

-- Main String Value
SELECT @mmRxClaim AS MainStringValue

-- Count Multiple Character for this number of space will be number of character
SELECT LEN(@mmRxClaim) - LEN(REPLACE(@mmRxClaim, 'GS', ' ')) AS CountMultipleCharacter

-- Count Single Character for this number of space will be one
SELECT LEN(@mmRxClaim) - LEN(REPLACE(@mmRxClaim, 'G', '')) AS CountSingleCharacter

Output:

In Ubuntu 20.04, I found following solution

First You need to export Android path variables. For that :

export ANDROID_SDK=~/Android/Sdk
export PATH=$ANDROID_SDK/emulator:$ANDROID_SDK/tools:$PATH

The paths may change according to your installation path. If Android Studio is installed using Ubuntu Software then path will be same as stated above.

If the export worked correctly, then following command should list your AVD names.

emulator -list-avds

In my case, I got the result

Nexus_5_API_30

Which is the name of my AVD.

If the above command have listed your AVD name, then you could run your AVD by :

emulator @YOUR_AVD_NAME

In my case

emulator @Nexus_5_API_30

You could add the export commands to .bashrc file to avoid typing export command every time you needed to run your AVD .

You can't do what you're asking natively with an array, but javascript objects are hashes, so you can say...

var hash = {};
hash['k1'] = 'abc';
...

Then you can retrieve using bracket or dot notation:

alert(hash['k1']); // alerts 'abc'
alert(hash.k1); // also alerts 'abc'

For arrays, check the underscore.js library in general and the detect method in particular. Using detect you could do something like...

_.detect(arr, function(x) { return x.name == 'k1' });

Or more generally

MyCollection = function() {
  this.arr = [];
}

MyCollection.prototype.getByName = function(name) {
  return _.detect(this.arr, function(x) { return x.name == name });
}

MyCollection.prototype.push = function(item) {
  this.arr.push(item);
}

etc...

My case:

• maven-javadoc-plugin with version 3.2.0 is displayed red in IntelliJ.
• Plugin is present in my local maven repo.
• Re-imported maven million times.
• Ran mvn clean install from the command line N times.
• All my maven settings in IntelliJ are correct.
• Tried to switch between Bundled and non-bundled Maven.
• Tried do delete the whole maven repo and to delete only the plugin from it.
• Nothing of the above worked.
• The only thing that almost always helps with modern IntelliJ IDEA versions is "Invalidate caches / Restart". It helped this time as well. maven-javadoc-plugin is not red anymore, and I can click on it and to to the source pom file of the plugin.

The following approach is correct:

<context:component-scan base-package="x.y.z.service, x.y.z.controller" /> 

Note that the error complains about x.y.z.dao.daoservice.LoginDAO, which is not in the packages mentioned above, perhaps you forgot to add it:

<context:component-scan base-package="x.y.z.service, x.y.z.controller, x.y.z.dao" /> 

I was able to overcome this by using the "vh" metric with max-height on the .modal-body element. 70vh looked about right for my uses.

.modal-body {
   overflow-y: auto;
   max-height: 70vh;
}

Here is code that will upload multiple images at once, into a specific folder!

The HTML:

<form method="post" enctype="multipart/form-data" id="image_upload_form" action="submit_image.php">
<input type="file" name="images" id="images" multiple accept="image/x-png, image/gif, image/jpeg, image/jpg" />
<button type="submit" id="btn">Upload Files!</button>
</form>
<div id="response"></div>
<ul id="image-list">

</ul>

The PHP:

<?php
$errors = $_FILES["images"]["error"];
foreach ($errors as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
    $name = $_FILES["images"]["name"][$key];
    //$ext = pathinfo($name, PATHINFO_EXTENSION);
    $name = explode("_", $name);
    $imagename='';
    foreach($name as $letter){
        $imagename .= $letter;
    }

    move_uploaded_file( $_FILES["images"]["tmp_name"][$key], "images/uploads/" .  $imagename);

}
}


echo "<h2>Successfully Uploaded Images</h2>";

And finally, the JavaSCript/Ajax:

(function () {
var input = document.getElementById("images"), 
    formdata = false;

function showUploadedItem (source) {
    var list = document.getElementById("image-list"),
        li   = document.createElement("li"),
        img  = document.createElement("img");
    img.src = source;
    li.appendChild(img);
    list.appendChild(li);
}   

if (window.FormData) {
    formdata = new FormData();
    document.getElementById("btn").style.display = "none";
}

input.addEventListener("change", function (evt) {
    document.getElementById("response").innerHTML = "Uploading . . ."
    var i = 0, len = this.files.length, img, reader, file;

    for ( ; i < len; i++ ) {
        file = this.files[i];

        if (!!file.type.match(/image.*/)) {
            if ( window.FileReader ) {
                reader = new FileReader();
                reader.onloadend = function (e) { 
                    showUploadedItem(e.target.result, file.fileName);
                };
                reader.readAsDataURL(file);
            }
            if (formdata) {
                formdata.append("images[]", file);
            }
        }   
    }

    if (formdata) {
        $.ajax({
            url: "submit_image.php",
            type: "POST",
            data: formdata,
            processData: false,
            contentType: false,
            success: function (res) {
                document.getElementById("response").innerHTML = res;
            }
        });
    }
}, false);
}());

Hope this helps

You can select the tables from information_schema

SELECT * FROM information_schema.tables 
WHERE table_schema = 'public'

Another way to do this on Lollipop, android 5.+ is setting a tint on a bitmap drawable like such:

<?xml version="1.0" encoding="utf-8"?>
<bitmap
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@drawable/ic_back"
    android:tint="@color/red_tint"/>

This will work for you if you have a limited number of colors you want to use on your drawables. Check out my blog post for more information.

If you're using .NET 2.0 (or later) you can use the nullable type:

DateTime? dt = null;

or

Nullable<DateTime> dt = null;

then later:

dt = new DateTime();

And you can check the value with:

if (dt.HasValue)
{
  // Do something with dt.Value
}

Or you can use it like:

DateTime dt2 = dt ?? DateTime.MinValue;

The top answer doesn't scale down the video when you're at browser widths of less than your video's width. Try using this CSS (with #bgvid being your video's id):

#bgvid {
     position: fixed;
     top: 50%;
     left: 50%;
     min-width: 100%;
     min-height: 100%;
     width: auto;
     height: auto;
     transform: translateX(-50%) translateY(-50%);
     -webkit-transform: translateX(-50%) translateY(-50%);
}

The correct answer to this particular questions is "don't select". Sometimes you have to select or activate, but 99% of the time you don't. If your code looks like

Select something
Do something to the selection
Select something else
Do something to the selection

You probably need to refactor and consider not selecting.

The error, Method 'Range' of object '_Worksheet' failed, error 1004, that you're getting is because the sheet with the button on it doesn't have a range named "Result". Most (maybe all) properties that return an object have a default Parent object. In this case, you're using the Range property to return a Range object. Because you don't qualify the Range property, Excel uses the default.

The default Parent object can be different based on the circumstances. If your code were in a standard module, then the ActiveSheet would be the default Parent and Excel would try to resolve ActiveSheet.Range("Result"). Your code is in a sheet's class module (the sheet with the button on it). When the unqualified reference is used there, the default Parent is the sheet that's attached to that module. In this case they're the same because the sheet has to be active to click the button, but that isn't always the case.

When Excel gives the error that includes text like '_Object' (yours said '_Worksheet') it's always referring to the default Parent object - the underscore gives that away. Generally the way to fix that is to qualify the reference by being explicit about the parent. But in the case of selecting and activating when you don't need to, it's better to just refactor the code.

Here's one way to write your code without any selecting or activating.

Private Sub cmdRecord_Click()

    Dim shSource As Worksheet
    Dim shDest As Worksheet
    Dim rNext As Range

    'Me refers to the sheet whose class module you're in
    'Me.Parent refers to the workbook
    Set shSource = Me.Parent.Worksheets("BxWsn Simulation")
    Set shDest = Me.Parent.Worksheets("Reslt Record")

    Set rNext = shDest.Cells(shDest.Rows.Count, 1).End(xlUp).Offset(1, 0)

    shSource.Range("Result").Copy

When I'm in a class module, like the sheet's class module that you're working in, I always try to do things in terms of that class. So I use Me.Parent instead of ActiveWorkbook. It makes the code more portable and prevents unexpected problems when things change.

I'm sure the code you have now runs in milliseconds, so you may not care, but avoiding selecting will definitely speed up your code and you don't have to set ScreenUpdating. That may become important as your code grows or in a different situation.

I recommend lxml for parsing HTML. See "Parsing HTML" (on the lxml site).

In my experience Beautiful Soup messes up on some complex HTML. I believe that is because Beautiful Soup is not a parser, rather a very good string analyzer.

In NodeJS, we have Buffers available, and string conversion with them is really easy. Better, it's easy to convert a Uint8Array to a Buffer. Try this code, it's worked for me in Node for basically any conversion involving Uint8Arrays:

let str = Buffer.from(uint8arr.buffer).toString();

We're just extracting the ArrayBuffer from the Uint8Array and then converting that to a proper NodeJS Buffer. Then we convert the Buffer to a string (you can throw in a hex or base64 encoding if you want).

If we want to convert back to a Uint8Array from a string, then we'd do this:

let uint8arr = new Uint8Array(Buffer.from(str));

Be aware that if you declared an encoding like base64 when converting to a string, then you'd have to use Buffer.from(str, "base64") if you used base64, or whatever other encoding you used.

This will not work in the browser without a module! NodeJS Buffers just don't exist in the browser, so this method won't work unless you add Buffer functionality to the browser. That's actually pretty easy to do though, just use a module like this, which is both small and fast!

These come from the class version. If you try to load something compiled for java 6 in a java 5 runtime you'll get the error, incompatible class version, got 50, expected 49. Or something like that.

See here in byte offset 7 for more info.

simple we can also use for an imageview

    imageView.setColorFilter(ContextCompat.getColor(context,
R.color.COLOR_YOUR_COLOR));

MySQL use HAVING statement for this tasks.

Your query would look like this:

SELECT g.group_id, COUNT(m.member_id) AS members
FROM groups AS g
LEFT JOIN group_members AS m USING(group_id)
GROUP BY g.group_id
HAVING members > 4

example when references have different names

SELECT g.id, COUNT(m.member_id) AS members
FROM groups AS g
LEFT JOIN group_members AS m ON g.id = m.group_id
GROUP BY g.id
HAVING members > 4

Also, make sure that you set indexes inside your database schema for keys you are using in JOINS as it can affect your site performance.

Create a custom Http class by extending the Angular 2 Http Provider and simply override the constructor and request method in you custom Http class. The example below adds Authorization header in every http request.

import {Injectable} from '@angular/core';
import {Http, XHRBackend, RequestOptions, Request, RequestOptionsArgs, Response, Headers} from '@angular/http';
import {Observable} from 'rxjs/Observable';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';

@Injectable()
export class HttpService extends Http {

  constructor (backend: XHRBackend, options: RequestOptions) {
    let token = localStorage.getItem('auth_token'); // your custom token getter function here
    options.headers.set('Authorization', `Bearer ${token}`);
    super(backend, options);
  }

  request(url: string|Request, options?: RequestOptionsArgs): Observable<Response> {
    let token = localStorage.getItem('auth_token');
    if (typeof url === 'string') { // meaning we have to add the token to the options, not in url
      if (!options) {
        // let's make option object
        options = {headers: new Headers()};
      }
      options.headers.set('Authorization', `Bearer ${token}`);
    } else {
    // we have to add the token to the url object
      url.headers.set('Authorization', `Bearer ${token}`);
    }
    return super.request(url, options).catch(this.catchAuthError(this));
  }

  private catchAuthError (self: HttpService) {
    // we have to pass HttpService's own instance here as `self`
    return (res: Response) => {
      console.log(res);
      if (res.status === 401 || res.status === 403) {
        // if not authenticated
        console.log(res);
      }
      return Observable.throw(res);
    };
  }
}

Then configure your main app.module.ts to provide the XHRBackend as the ConnectionBackend provider and the RequestOptions to your custom Http class:

import { HttpModule, RequestOptions, XHRBackend } from '@angular/http';
import { HttpService } from './services/http.service';
...
@NgModule({
  imports: [..],
  providers: [
    {
      provide: HttpService,
      useFactory: (backend: XHRBackend, options: RequestOptions) => {
        return new HttpService(backend, options);
      },
      deps: [XHRBackend, RequestOptions]
    }
  ],
  bootstrap: [ AppComponent ]
})

After that, you can now use your custom http provider in your services. For example:

import { Injectable }     from '@angular/core';
import {HttpService} from './http.service';

@Injectable()
class UserService {
  constructor (private http: HttpService) {}

  // token will added automatically to get request header
  getUser (id: number) {
    return this.http.get(`/users/${id}`).map((res) => {
      return res.json();
    } );
  }
}

I set the below xml to the background of the Image View as Drawable. It works.

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FFFFFF" />
    <stroke android:width="1dp" android:color="#000000" />
    <padding android:left="1dp" android:top="1dp" android:right="1dp"
        android:bottom="1dp" />
</shape>

And then add android:background="@drawable/yourXmlFileName" to your ImageView

You need to do type assertion for converting your interface{} to int value.

iAreaId := val.(int)
iAreaId, ok := val.(int)

More information is available.

Since C++11 you can make use of std::all_of and ::isdigit:

#include <algorithm>
#include <cctype>
#include <iostream>
#include <string_view>

int main([[maybe_unused]] int argc, [[maybe_unused]] char *argv[])
{
    auto isInt = [](std::string_view str) -> bool {
        return std::all_of(str.cbegin(), str.cend(), ::isdigit);
    };

    for(auto &test : {"abc", "123abc", "123.0", "+123", "-123", "123"}) {
        std::cout << "Is '" << test << "' numeric? " 
            << (isInt(test) ? "true" : "false") << std::endl;
    }

    return 0;
}

First of all, there're two kinds of keystores.

Individual and General

The application will use the one indicated in the startup or the default of the system.

It will be a different folder if JRE or JDK is running, or if you check the personal or the "global" one.

They are encrypted too

In short, the path will be like:

$JAVA_HOME/lib/security/cacerts for the "general one", who has all the CA for the Authorities and is quite important.

As a replacement for some of orsogufo's code, because I recently went with a dictionary for this same problem myself, here is my [] operator:

public string this[string key]
{
    get { return properties.ContainsKey(key) ? properties[key] : null; }

    set
    {
        if (properties.ContainsKey(key))
        {
            properties[key] = value;
        }
        else
        {
            properties.Add(key, value);
        }
    }
}

With this implementation, the setter will add new key-value pairs when you use []= if they do not already exist in the dictionary.

Also, for me properties is an IDictionary and in constructors I initialize it to new SortedDictionary<string, string>().

Maybe this is a good example of when to use nested classes?

// ORIGINAL
class ImageCacheSettings { }
class ImageCacheEntry { }
class ImageCache
{
    ImageCacheSettings mSettings;
    List<ImageCacheEntry> mEntries;
}

And:

// REFACTORED
class ImageCache
{
    Settings mSettings;
    List<Entry> mEntries;

    class Settings {}
    class Entry {}
}

PS: I've not taken into account which access modifiers should be applied (private, protected, public, internal)

I had such problem for windows. And I decided it so: startApp.cmd:

@set JAVA_HOME=C:\jdk160_24
@set PATH=%JAVA_HOME%/bin;%PATH%
@cd /D C:\app\

@start /b C:\WINDOWS\system32\cscript.exe 
C:\app\start.js

and saved it cmd file in dir C:\scripts next file is runApp.bat:

C:\scripts\startApp.cmd
