How do I check if something is (not) in a list in Python?

The cheapest and most readable solution is using the in operator (or in your specific case, not in). As mentioned in the documentation,

The operators in and not in test for membership. x in s evaluates to True if x is a member of s, and False otherwise. x not in s returns the negation of x in s.

Additionally,

The operator not in is defined to have the inverse true value of in.

y not in x is logically the same as not y in x.

Here are a few examples:

'a' in [1, 2, 3]
# False

'c' in ['a', 'b', 'c']
# True

'a' not in [1, 2, 3]
# True

'c' not in ['a', 'b', 'c']
# False

This also works with tuples, since tuples are hashable (as a consequence of the fact that they are also immutable):

(1, 2) in [(3, 4), (1, 2)]
#  True

If the object on the RHS defines a __contains__() method, in will internally call it, as noted in the last paragraph of the Comparisons section of the docs.

... in and not in, are supported by types that are iterable or implement the __contains__() method. For example, you could (but shouldn't) do this:

[3, 2, 1].__contains__(1)
# True

in short-circuits, so if your element is at the start of the list, in evaluates faster:

lst = list(range(10001))
%timeit 1 in lst
%timeit 10000 in lst  # Expected to take longer time.

68.9 ns ± 0.613 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)
178 µs ± 5.01 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)

If you want to do more than just check whether an item is in a list, there are options:

• list.index can be used to retrieve the index of an item. If that element does not exist, a ValueError is raised.
• list.count can be used if you want to count the occurrences.

The XY Problem: Have you considered sets?

Ask yourself these questions:

• do you need to check whether an item is in a list more than once?
• Is this check done inside a loop, or a function called repeatedly?
• Are the items you're storing on your list hashable? IOW, can you call hash on them?

If you answered "yes" to these questions, you should be using a set instead. An in membership test on lists is O(n) time complexity. This means that python has to do a linear scan of your list, visiting each element and comparing it against the search item. If you're doing this repeatedly, or if the lists are large, this operation will incur an overhead.

set objects, on the other hand, hash their values for constant time membership check. The check is also done using in:

1 in {1, 2, 3} 
# True

'a' not in {'a', 'b', 'c'}
# False

(1, 2) in {('a', 'c'), (1, 2)}
# True

If you're unfortunate enough that the element you're searching/not searching for is at the end of your list, python will have scanned the list upto the end. This is evident from the timings below:

l = list(range(100001))
s = set(l)

%timeit 100000 in l
%timeit 100000 in s

2.58 ms ± 58.9 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
101 ns ± 9.53 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

As a reminder, this is a suitable option as long as the elements you're storing and looking up are hashable. IOW, they would either have to be immutable types, or objects that implement __hash__.

The below code will return username group membership using the samaccountname. You can modify it to get input from a file or change the query to get accounts with non expiring passwords etc

$location = "c:\temp\Peace2.txt"
$users = (get-aduser -filter *).samaccountname
$le = $users.length
for($i = 0; $i -lt $le; $i++){
  $output = (get-aduser $users[$i] | Get-ADPrincipalGroupMembership).name
  $users[$i] + " " + $output 
  $z =  $users[$i] + " " + $output 
  add-content $location $z
}

Sample Output:

Administrator Domain Users Administrators Schema Admins Enterprise Admins Domain Admins Group Policy Creator Owners
Guest Domain Guests Guests
krbtgt Domain Users Denied RODC Password Replication Group
Redacted Domain Users CompanyUsers Production
Redacted Domain Users CompanyUsers Production
Redacted Domain Users CompanyUsers Production

For having hover effect you can simply try this code

import React from "react";
  import "./styles.css";

    export default function App() {

      function MouseOver(event) {
        event.target.style.background = 'red';
      }
      function MouseOut(event){
        event.target.style.background="";
      }
      return (
        <div className="App">
          <button onMouseOver={MouseOver} onMouseOut={MouseOut}>Hover over me!</button>
        </div>
      );
    }

Or if you want to handle this situation using useState() hook then you can try this piece of code

import React from "react";
import "./styles.css";


export default function App() {
   let [over,setOver]=React.useState(false);

   let buttonstyle={
    backgroundColor:''
  }

  if(over){
    buttonstyle.backgroundColor="green";
  }
  else{
    buttonstyle.backgroundColor='';
  }

  return (
    <div className="App">
      <button style={buttonstyle}
      onMouseOver={()=>setOver(true)} 
      onMouseOut={()=>setOver(false)}
      >Hover over me!</button>
    </div>
  );
}

Both of the above code will work for hover effect but first procedure is easier to write and understand

I didn't see an answer that's clean and suitable for production-ready software, so here it goes:

/*
 * Get current error_reporting value,
 * so that we don't lose preferences set in php.ini and .htaccess
 * and accidently reenable message types disabled in those.
 *
 * If you want to disable e.g. E_STRICT on a global level,
 * use php.ini (or .htaccess for folder-level)
 */
$old_error_reporting = error_reporting();

/*
 * Disable E_STRICT on top of current error_reporting.
 *
 * Note: do NOT use ^ for disabling error message types,
 * as ^ will re-ENABLE the message type if it happens to be disabled already!
 */
error_reporting($old_error_reporting & ~E_STRICT);


// code that should not emit E_STRICT messages goes here


/*
 * Optional, depending on if/what code comes after.
 * Restore old settings.
 */
error_reporting($old_error_reporting);

add the muted property to video tag

<video id="myvid" muted>

then play it using javascript and set muted to false

var myvideo = document.getElementById("myvid");
myvideo.play();
myvideo.muted = false;

edit: need user interaction (at least click anywhere in the page to work)

Since Java 8:

List<String> myList = map.keySet().stream().collect(Collectors.toList());

If you have latest compiler, you can change the following in your build settings:

 C++ Language Dialect    C++14[-std=c++14]

This works for me.

make sure you have these permissions:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

Then make some activity and register a LocationListener

package com.example.location;

import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.view.View;
import com.actionbarsherlock.app.SherlockFragmentActivity;
import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;

public class LocationActivity extends SherlockFragmentActivity implements LocationListener     {
private GoogleMap map;
private LocationManager locationManager;
private static final long MIN_TIME = 400;
private static final float MIN_DISTANCE = 1000;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.map);
    map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MIN_TIME, MIN_DISTANCE, this); //You can also use LocationManager.GPS_PROVIDER and LocationManager.PASSIVE_PROVIDER        
}

@Override
public void onLocationChanged(Location location) {
    LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
    CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 10);
    map.animateCamera(cameraUpdate);
    locationManager.removeUpdates(this);
}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) { }

@Override
public void onProviderEnabled(String provider) { }

@Override
public void onProviderDisabled(String provider) { }
}

map.xml

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>

You can stop the 2-line separation in the output by using

    with open('t.ini') as f:
       for line in f:
           print line.strip()
           if 'str' in line:
              break

You can have it this way:

It is important to mind the commas after each struct item or set of items.

earnings := []LineItemsType{

        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
    }

Open angular.json file and find budgets keyword.

It should look like:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "2mb",
          "maximumError": "5mb"
       }
    ]

As you’ve probably guessed you can increase the maximumWarning value to prevent this warning, i.e.:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "4mb", <===
          "maximumError": "5mb"
       }
    ]

What does budgets mean?

A performance budget is a group of limits to certain values that affect site performance, that may not be exceeded in the design and development of any web project.

In our case budget is the limit for bundle sizes.

I'm using jQuery and JavaScript and it works fine for me:

var rege = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
if(rege.test($('#uemail').val())){ //do something }

While a regexp would suit here just fine, I'll present you with an alternative method. It might be a tad faster than the equivalent regexp, but life's all about choices (...or something).

$length = strlen($urlString);
for ($i=0; $i<$length; i++) {
  if ($urlString[$i] === '?') {
    $urlString[$i+1] = '';
    break;
  }
}

Weird, I know.

I originally came in here to find how to make PyTest print in VSCode's console while running/debugging the unit test from there. This can be done with the following launch.json configuration. Given .venv the virtual environment folder.

    "version": "0.2.0",
    "configurations": [
        {
            "name": "PyTest",
            "type": "python",
            "request": "launch",
            "stopOnEntry": false,
            "pythonPath": "${config:python.pythonPath}",
            "module": "pytest",
            "args": [
                "-sv"
            ],
            "cwd": "${workspaceRoot}",
            "env": {},
            "envFile": "${workspaceRoot}/.venv",
            "debugOptions": [
                "WaitOnAbnormalExit",
                "WaitOnNormalExit",
                "RedirectOutput"
            ]
        }
    ]
}

In addition to using pure threads or the Celery queue (note that flask-celery is no longer required), you could also have a look at flask-apscheduler:

https://github.com/viniciuschiele/flask-apscheduler

A simple example copied from https://github.com/viniciuschiele/flask-apscheduler/blob/master/examples/jobs.py:

from flask import Flask
from flask_apscheduler import APScheduler


class Config(object):
    JOBS = [
        {
            'id': 'job1',
            'func': 'jobs:job1',
            'args': (1, 2),
            'trigger': 'interval',
            'seconds': 10
        }
    ]

    SCHEDULER_API_ENABLED = True


def job1(a, b):
    print(str(a) + ' ' + str(b))

if __name__ == '__main__':
    app = Flask(__name__)
    app.config.from_object(Config())

    scheduler = APScheduler()
    # it is also possible to enable the API directly
    # scheduler.api_enabled = True
    scheduler.init_app(app)
    scheduler.start()

    app.run()

Code snippet for both recursive and non-recursive approaches:

//helper method to get the list of files from the HDFS path
public static List<String>
    listFilesFromHDFSPath(Configuration hadoopConfiguration,
                          String hdfsPath,
                          boolean recursive) throws IOException,
                                        IllegalArgumentException
{
    //resulting list of files
    List<String> filePaths = new ArrayList<String>();

    //get path from string and then the filesystem
    Path path = new Path(hdfsPath);  //throws IllegalArgumentException
    FileSystem fs = path.getFileSystem(hadoopConfiguration);

    //if recursive approach is requested
    if(recursive)
    {
        //(heap issues with recursive approach) => using a queue
        Queue<Path> fileQueue = new LinkedList<Path>();

        //add the obtained path to the queue
        fileQueue.add(path);

        //while the fileQueue is not empty
        while (!fileQueue.isEmpty())
        {
            //get the file path from queue
            Path filePath = fileQueue.remove();

            //filePath refers to a file
            if (fs.isFile(filePath))
            {
                filePaths.add(filePath.toString());
            }
            else   //else filePath refers to a directory
            {
                //list paths in the directory and add to the queue
                FileStatus[] fileStatuses = fs.listStatus(filePath);

It is simple, as a java, Android also supporting singleton. -

Singleton is a part of Gang of Four design pattern and it is categorized under creational design patterns.

-> Static member : This contains the instance of the singleton class.

-> Private constructor : This will prevent anybody else to instantiate the Singleton class.

-> Static public method : This provides the global point of access to the Singleton object and returns the instance to the client calling class.

1. create private instance
2. create private constructor

3. use getInstance() of Singleton class

   public class Logger{
   private static Logger   objLogger;
   private Logger(){
   
           //ToDo here
   
   }
   public static Logger getInstance()
   {
       if (objLogger == null)
      {
         objLogger = new Logger();
      }
      return objLogger;
      }
   
   }
   

while use singleton -

Logger.getInstance();

This was a good waste of an hour of my time. For you eager beavers, the following format worked for me:

<input type="datetime-local" name="to" id="to" value="2014-12-08T15:43:00">

The spec was a little confusing to me, it said to use RFC 3339, but on my PHP server when I used the format DATE_RFC3339 it wasn't initializing my hmtl input :( PHP's constant for DATE_RFC3339 is "Y-m-d\TH:i:sP" at the time of writing, it makes sense that you should get rid of the timezone info (we're using datetime-LOCAL, folks). So the format that worked for me was:

"Y-m-d\TH:i:s"

I would've thought it more intuitive to be able to set the value of the datepicker as the datepicker displays the date, but I'm guessing the way it is displayed differs across browsers.

This might work for you:

sed 'y/\\/\//'

You need the jQuery and Boostrap Javascript files included in your HTML page for the toggle to work. (Make sure you include jQuery before Bootstrap.)

<html>
   <head>
       // stylesheets here
       <link rel="stylesheet" href=""/> 
   </head>
   <body>
      //your html code here

      // js scripts here
      // note jquery tag has to go before boostrap
      <script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>
      <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script>
   </body>
</html>

TL;DR ...and late to the party, but that short explanation might help future googlers..

In general that error message means that the replacement doesn't fit into the corresponding column of the dataframe.

A minimal example:

df <- data.frame(a = 1:2); df$a <- 1:3

throws the error

Error in $<-.data.frame(*tmp*, a, value = 1:3) : replacement has 3 rows, data has 2

which is clear, because the vector a of df has 2 entries (rows) whilst the vector we try to replace it has 3 entries (rows).

Your code isn't working, because the hidden attibute is not supported in versions of IE before v11

If you need to support IE before version 11, add a CSS style to hide when the hidden attribute is present:

*[hidden] { display: none; }

You can examine the url through several Request fields:

Imagine your application is listening on the following application root:

http://www.example.com/myapplication

And a user requests the following URI:

http://www.example.com/myapplication/foo/page.html?x=y

In this case the values of the above mentioned attributes would be the following:

    path             /foo/page.html
    full_path        /foo/page.html?x=y
    script_root      /myapplication
    base_url         http://www.example.com/myapplication/foo/page.html
    url              http://www.example.com/myapplication/foo/page.html?x=y
    url_root         http://www.example.com/myapplication/

You can easily extract the host part with the appropriate splits.

the second argument in ROUNDUP, eg =ROUNDUP(12345.6789,3) refers to the negative of the base-10 column with that power of 10, that you want rounded up. eg 1000 = 10^3, so to round up to the next highest 1000, use ,-3)

=ROUNDUP(12345.6789,-4) = 20,000
=ROUNDUP(12345.6789,-3) = 13,000
=ROUNDUP(12345.6789,-2) = 12,400
=ROUNDUP(12345.6789,-1) = 12,350
=ROUNDUP(12345.6789,0) = 12,346
=ROUNDUP(12345.6789,1) = 12,345.7
=ROUNDUP(12345.6789,2) = 12,345.68
=ROUNDUP(12345.6789,3) = 12,345.679

So, to answer your question: if your value is in A1, use =ROUNDUP(A1,-1)

You can use:

Sub returnname(ByVal TableName As String)

MsgBox (Range("Table15").Rows.count)

End Sub

and call the function as below

Sub called()

returnname "Table15"

End Sub

To get the value you would do this:

document.getElementById("genderf").value;

But to check, whether the radio button is checked or selected:

document.getElementById("genderf").checked;

I know this has been said earlier, but jQuery Autocomplete will do exactly what you need. You should check out the docs as the autocomplete is very customizable. If you are familiar with javascript then you should be able to work this out. If not I can give you a few pointers, as I have done this once before, but beware I am not well versed in javascript myself either, so bear with me on this.

I think the first thing you should do is just get a simple autocomplete text field working on your page, and then you can customize it from there.

The autocomplete widget accepts JSON data as it's 'source:' option. So you should set-up your app to produce the 20 top level categories, and subcategories in JSON format.

The next thing to know is that when the user types into your textfield, the autocomplete widget will send the typed values in a parameter called "term".

So let's say you first set-up your site to deliver the JSON data from a URL like this:

/categories.json

Then your autocomplete source: option would be 'source: /categories.json'.

When a user types into the textfield, such as 'first-cata...' the autocomplete widget will start sending the value in the 'term' parameter like this:

/categories.json?term=first-cata

This will return JSON data back to the widget filtered by anything that matches 'first-cata', and this is displayed as an autocomplete suggestion.

I am not sure what you are programming in, but you can specify how the 'term' parameter finds a match. So you can customize this, so that the term finds a match in the middle of a word if you want. Example, if the user types 'or' you code could make a match on 'sports'.

Lastly, you made a comment that you want to be able to select a category name but have the autocomplete widget submit the category ID not the name.

This can easily be done with a hidden field. This is what is shown in the jQuery autocomplete docs.

When a user selects a category, your JavaScript should update a hidden field with the ID.

I know this answer is not very detailed, but that is mainly because I am not sure what you are programming in, but the above should point you in the right direction. The thing to know is that you can do practically any customizing you want with this widget, if you are willing to spend the time to learn it.

These are the broad strokes, but you can look here for some notes I made when I implemented something similar to what you want in a Rails app.

Hope this helped.

SelectMany() lets you collapse a multidimensional sequence in a way that would otherwise require a second Select() or loop.

More details at this blog post.

A simple way :

select  * from  hockey_stats 
where  game_date >= '2012-03-11' and game_date  <= '2012-05-11'

To check that the file you're trying to open actually exists, you can change directories in terminal using cd. To change to ~/Desktop/sass/css: cd ~/Desktop/sass/css. To see what files are in the directory: ls.

If you want information about either of those commands, use the man page: man cd or man ls, for example.

Google for "basic unix command line commands" or similar; that will give you numerous examples of moving around, viewing files, etc in the command line.

On Mac OS X, you can also use open to open a finder window: open . will open the current directory in finder. (open ~/Desktop/sass/css will open the ~/Desktop/sass/css).

First Way:

You didn't create the directory. Also, you are passing an absolute path to openFileOutput(), which is wrong.

Second way:

You created an empty file with the desired name, which then prevented you from creating the directory. Also, you are passing an absolute path to openFileOutput(), which is wrong.

Third way:

You didn't create the directory. Also, you are passing an absolute path to openFileOutput(), which is wrong.

Fourth Way:

You didn't create the directory. Also, you are passing an absolute path to openFileOutput(), which is wrong.

Fifth way:

You didn't create the directory. Also, you are passing an absolute path to openFileOutput(), which is wrong.

Correct way:

1. Create a File for your desired directory (e.g., File path=new File(getFilesDir(),"myfolder");)
2. Call mkdirs() on that File to create the directory if it does not exist
3. Create a File for the output file (e.g., File mypath=new File(path,"myfile.txt");)
4. Use standard Java I/O to write to that File (e.g., using new BufferedWriter(new FileWriter(mypath)))

If you want to fit other type of models, like a dose-response curve using logistic models you would also need to create more data points with the function predict if you want to have a smoother regression line:

fit: your fit of a logistic regression curve

#Create a range of doses:
mm <- data.frame(DOSE = seq(0, max(data$DOSE), length.out = 100))
#Create a new data frame for ggplot using predict and your range of new 
#doses:
fit.ggplot=data.frame(y=predict(fit, newdata=mm),x=mm$DOSE)

ggplot(data=data,aes(x=log10(DOSE),y=log(viability)))+geom_point()+
geom_line(data=fit.ggplot,aes(x=log10(x),y=log(y)))

for Swift 3.0 add image on leftside of textField

textField.leftView = UIImageView(image: "small-calendar")
textField.leftView?.frame = CGRect(x: 0, y: 5, width: 20 , height:20)
textField.leftViewMode = .always

This might not be very elegant, but works for me:

d = {'a': 3, 'b': 2, 'c': 3, 'd': 4, 'e': 5}

x= 0
for key, val in d.items():
    if x == 2:
        break
    else:
        x += 1
        # Do something with the first two key-value pairs

Workaround

You can do this using Javascript:

<html><head>
<script type="text/javascript">
function logout() {
    var xmlhttp;
    if (window.XMLHttpRequest) {
          xmlhttp = new XMLHttpRequest();
    }
    // code for IE
    else if (window.ActiveXObject) {
      xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    if (window.ActiveXObject) {
      // IE clear HTTP Authentication
      document.execCommand("ClearAuthenticationCache");
      window.location.href='/where/to/redirect';
    } else {
        xmlhttp.open("GET", '/path/that/will/return/200/OK', true, "logout", "logout");
        xmlhttp.send("");
        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4) {window.location.href='/where/to/redirect';}
        }


    }


    return false;
}
</script>
</head>
<body>
<a href="#" onclick="logout();">Log out</a>
</body>
</html>

What is done above is:

• for IE - just clear auth cache and redirect somewhere

• for other browsers - send an XMLHttpRequest behind the scenes with 'logout' login name and password. We need to send it to some path that will return 200 OK to that request (i.e. it shouldn't require HTTP authentication).

Replace '/where/to/redirect' with some path to redirect to after logging out and replace '/path/that/will/return/200/OK' with some path on your site that will return 200 OK.

You can retrieve the length of the file with File#length(), which will return a value in bytes, so you need to divide this by 1024*1024 to get its value in mb.

OpenID and OAuth are each HTTP-based protocols for authentication and/or authorization. Both are intended to allow users to perform actions without giving authentication credentials or blanket permissions to clients or third parties. While they are similar, and there are proposed standards to use them both together, they are separate protocols.

OpenID is intended for federated authentication. A client accepts an identity assertion from any provider (although clients are free to whitelist or blacklist providers).

OAuth is intended for delegated authorization. A client registers with a provider, which provides authorization tokens which it will accept to perform actions on the user's behalf.

OAuth is currently better suited for authorization, because further interactions after authentication are built into the protocol, but both protocols are evolving. OpenID and its extensions could be used for authorization, and OAuth can be used for authentication, which can be thought of as a no-op authorization.

The || operator is "concatenate" - it joins together the two strings of its operands.

From http://www.sqlite.org/lang_expr.html

For padding, the seemingly-cheater way I've used is to start with your target string, say '0000', concatenate '0000423', then substr(result, -4, 4) for '0423'.

Update: Looks like there is no native implementation of "lpad" or "rpad" in SQLite, but you can follow along (basically what I proposed) here: http://verysimple.com/2010/01/12/sqlite-lpad-rpad-function/

-- the statement below is almost the same as
-- select lpad(mycolumn,'0',10) from mytable

select substr('0000000000' || mycolumn, -10, 10) from mytable

-- the statement below is almost the same as
-- select rpad(mycolumn,'0',10) from mytable

select substr(mycolumn || '0000000000', 1, 10) from mytable

Here's how it looks:

SELECT col1 || '-' || substr('00'||col2, -2, 2) || '-' || substr('0000'||col3, -4, 4)

it yields

"A-01-0001"
"A-01-0002"
"A-12-0002"
"C-13-0002"
"B-11-0002"

#if DEBUG
bool bypassCheck=TRUE_OR_FALSE;//i will decide depending on what i am debugging
#else
bool bypassCheck = false; //NEVER bypass it
#endif

Make sure you have the checkbox to define DEBUG checked in your build properties.

Exception code c0000005 is the code for an access violation. That means that your program is accessing (either reading or writing) a memory address to which it does not have rights. Most commonly this is caused by:

• Accessing a stale pointer. That is accessing memory that has already been deallocated. Note that such stale pointer accesses do not always result in access violations. Only if the memory manager has returned the memory to the system do you get an access violation.
• Reading off the end of an array. This is when you have an array of length N and you access elements with index >=N.

To solve the problem you'll need to do some debugging. If you are not in a position to get the fault to occur under your debugger on your development machine you should get a crash dump file and load it into your debugger. This will allow you to see where in the code the problem occurred and hopefully lead you to the solution. You'll need to have the debugging symbols associated with the executable in order to see meaningful stack traces.

Event handlers expect one parameter which is the event that was fired. You happen to be renaming that to 'myMessage' and therefore you are alerting the event object rather than your message.

A closure can allow you to reference the variable you have defined outside the function however if you are using Jquery you may want to look at its event specific API e.g.

http://docs.jquery.com/Events/bind#typedatafn

This has an option for passing in your own data.

Put your Thread.sleep in a try catch block

try {
    //thread to sleep for the specified number of milliseconds
    Thread.sleep(100);
} catch ( java.lang.InterruptedException ie) {
    System.out.println(ie);
}

Joe Casadonte's one-liner is perfect, except if you run with set -e, i.e. if your script is set to fail on error, and if there are no cronjobs yet. In that case, the one-liner will NOT create the cronjob, but will NOT stop the script. The silent failure can be very misleading.

The reason is that crontab -l returns with a 1 return code, causing the subsequent command (the echo) not to be executed... thus the cronjob is not created. But since they are executed as a subprocess (because of the parenthesis) they don't stop the script.

(Interestingly, if you run the same command again, it will work: once you have executed crontab - once, crontab -l still outputs nothing, but it doesn't return an error anymore (you don't get the no crontab for <user> message anymore). So the subsequent echo is executed and the crontab is created)

In any case, if you run with set -e, the line must be:

(crontab -l 2>/dev/null || true; echo "*/5 * * * * /path/to/job -with args") | crontab -

It might be an easiest way-

    String recipientList = mEditTextTo.getText().toString();
    String[] recipients = recipientList.split(",");

    String subject = mEditTextSubject.getText().toString();
    String message = mEditTextMessage.getText().toString();

    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.putExtra(Intent.EXTRA_EMAIL, recipients);
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    intent.putExtra(Intent.EXTRA_TEXT, message);

    intent.setType("message/rfc822");
    startActivity(Intent.createChooser(intent, "Choose an email client"));

You can simulate a readonly select box using the CSS pointer-events property:

select[readonly]
{
    pointer-events: none;
}

The HTML tabindex property will also prevent it from being selected by keyboard tabbing:

<select tabindex="-1">

select[readonly]_x000D_
{_x000D_
    pointer-events: none;_x000D_
}_x000D_
_x000D_
_x000D_
/* irrelevent styling */_x000D_
_x000D_
*_x000D_
{_x000D_
  box-sizing: border-box;_x000D_
}_x000D_
_x000D_
*[readonly]_x000D_
{_x000D_
  background: #fafafa;_x000D_
  border: 1px solid #ccc;_x000D_
  color: #555;_x000D_
}_x000D_
_x000D_
input, select_x000D_
{_x000D_
  display:block;_x000D_
  width: 20rem;_x000D_
  padding: 0.5rem;_x000D_
  margin-bottom: 1rem;_x000D_
}

<form>_x000D_
  <input type="text" value="this is a normal text box">_x000D_
  <input type="text" readonly value="this is a readonly text box">_x000D_
  <select readonly tabindex="-1">_x000D_
    <option>This is a readonly select box</option>_x000D_
    <option>Option 2</option>_x000D_
  </select>_x000D_
  <select>_x000D_
    <option>This is a normal select box</option>_x000D_
    <option>Option 2</option>_x000D_
  </select>_x000D_
</form>

Just to add to roya's answer. In c# 6.0 you can now use string interpolation:

Console.WriteLine($"{customer[DisplayPos],10}" +
                  $"{salesFigures[DisplayPos],10}" +
                  $"{feePayable[DisplayPos],10}" +
                  $"{seventyPercentValue,10}" +
                  $"{thirtyPercentValue,10}");

This can actually be one line without all the extra dollars, I just think it makes it a bit easier to read like this.

And you could also use a static import on System.Console, allowing you to do this:

using static System.Console;

WriteLine(/* write stuff */);

You may have select option values such as "Choose option". If you want to keep that value and clear the rest of the values you can first remove all the values and append "Choose Option"

<select multiple='multiple' id='selectName'> 
    <option selected disabled>Choose Option</option>
    <option>1</option> 
    <option>2</option> 
    <option>3</option>    
</select>

Jquery

$('#selectName option').remove(); // clear all values 
$('#selectName ').append('<option selected disabled>Choose Option</option>'); //append what you want to keep

In your test code your are trying to pass App to the spyOn function, but spyOn will only work with objects, not classes. Generally you need to use one of two approaches here:

1) Where the click handler calls a function passed as a prop, e.g.

class App extends Component {

  myClickFunc = () => {
      console.log('clickity clickcty');
      this.props.someCallback();
  }
  render() {
    return (
      <div className="App">
        <div className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro" onClick={this.myClickFunc}>
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

You can now pass in a spy function as a prop to the component, and assert that it is called:

describe('my sweet test', () => {
 it('clicks it', () => {
    const spy = jest.fn();
    const app = shallow(<App someCallback={spy} />)
    const p = app.find('.App-intro')
    p.simulate('click')
    expect(spy).toHaveBeenCalled()
 })
})

2) Where the click handler sets some state on the component, e.g.

class App extends Component {
  state = {
      aProperty: 'first'
  }

  myClickFunc = () => {
      console.log('clickity clickcty');
      this.setState({
          aProperty: 'second'
      });
  }
  render() {
    return (
      <div className="App">
        <div className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro" onClick={this.myClickFunc}>
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

You can now make assertions about the state of the component, i.e.

describe('my sweet test', () => {
 it('clicks it', () => {
    const app = shallow(<App />)
    const p = app.find('.App-intro')
    p.simulate('click')
    expect(app.state('aProperty')).toEqual('second');
 })
})

There is also this one:

hash = { foo: "bar", baz: "qux" }
hash.map(&:last) #=> ["bar", "qux"]

Why it works:

The & calls to_proc on the object, and passes it as a block to the method.

something {|i| i.foo }
something(&:foo)

If you want to append a file instead of constantly making a new one/deleting the old one's content, use double > marks. A single > mark will overwrite all the file's content.

Overwrite file

MyCommand.exe>file.txt

^This will open file.txt if it already exists and overwrite the data, or create a new file and fill it with your output

Append file from its end-point

MyCommand.exe>>file.txt

^This will append file.txt from its current end of file if it already exists, or create a new file and fill it with your output.

Update #1 (advanced):

My batch-fu has improved over time, so here's some minor updates.

If you want to differentiate between error output and normal output for a program that correctly uses Standard streams, STDOUT/STDERR, you can do this with minor changes to the syntax. I'll just use > for overwriting for these examples, but they work perfectly fine with >> for append, in regards to file-piping output re-direction.

The 1 before the >> or > is the flag for STDOUT. If you need to actually output the number one or two before the re-direction symbols, this can lead to strange, unintuitive errors if you don't know about this mechanism. That's especially relevant when outputting a single result number into a file. 2 before the re-direction symbols is for STDERR.

Now that you know that you have more than one stream available, this is a good time to show the benefits of outputting to nul. Now, outputting to nul works the same way conceptually as outputting to a file. You don't see the content in your console. Instead of it going to file or your console output, it goes into the void.

STDERR to file and suppress STDOUT

MyCommand.exe 1>nul 2>errors.txt

STDERR to file to only log errors. Will keep STDOUT in console

MyCommand.exe 2>errors.txt

STDOUT to file and suppress STDERR

MyCommand.exe 1>file.txt 2>nul

STDOUT only to file. Will keep STDERR in console

MyCommand.exe 1>file.txt

STDOUT to one file and STDERR to another file

MyCommand.exe 1>stdout.txt 2>errors.txt

The only caveat I have here is that it can create a 0-byte file for an unused stream if one of the streams never gets used. Basically, if no errors occurred, you might end up with a 0-byte errors.txt file.

Update #2

I started noticing weird behavior when writing console apps that wrote directly to STDERR, and realized that if I wanted my error output to go to the same file when using basic piping, I either had to combine streams 1 and 2 or just use STDOUT. The problem with that problem is I didn't know about the correct way to combine streams, which is this:

%command% > outputfile 2>&1

Therefore, if you want all STDOUT and STDERR piped into the same stream, make sure to use that like so:

MyCommand.exe > file.txt 2>&1

The redirector actually defaults to 1> or 1>>, even if you don't explicitly use 1 in front of it if you don't use a number in front of it, and the 2>&1 combines the streams.

Update #3 (simple)

Null for Everything

If you want to completely suppress STDOUT and STDERR you can do it this way. As a warning not all text pipes use STDOUT and STDERR but it will work for a vast majority of use cases.

STD* to null MyCommand.exe>nul 2>&1

Copying a CMD or Powershell session's command output

If all you want is the command output from a CMD or Powershell session that you just finished up, or any other shell for that matter you can usually just select that console from that session, CTRL + A to select all content, then CTRL + C to copy the content. Then you can do whatever you like with the copied content while it's in your clipboard.

Only stopped containers can be listed using:

docker ps --filter "status=exited"

or

docker ps -f "status=exited"

If you don't want 3D border use:

border:#f00 1px solid;

Use an HTML line break (<br />) to force a line break within a table cell:

|Something|Something else<br />that's rather long|Something else|

SOURCE: https://git-scm.com/book/en/v2/Distributed-Git-Maintaining-a-Project#Integrating-Contributed-Work

The other way to move introduced work from one branch to another is to cherry-pick it. A cherry-pick in Git is like a rebase for a single commit. It takes the patch that was introduced in a commit and tries to reapply it on the branch you’re currently on. This is useful if you have a number of commits on a topic branch and you want to integrate only one of them, or if you only have one commit on a topic branch and you’d prefer to cherry-pick it rather than run rebase. For example, suppose you have a project that looks like this:

If you want to pull commit e43a6 into your master branch, you can run

$ git cherry-pick e43a6
Finished one cherry-pick.
[master]: created a0a41a9: "More friendly message when locking the index fails."
 3 files changed, 17 insertions(+), 3 deletions(-)

This pulls the same change introduced in e43a6, but you get a new commit SHA-1 value, because the date applied is different. Now your history looks like this:

Now you can remove your topic branch and drop the commits you didn’t want to pull in.

It seems that you can use regexp too

WHERE NOT REGEXP_LIKE(field, '^Done|^Finished')

I'm not sure how well this will perform though ... see here

If you are using FormBuilder, see @dfsq's answer.

If you are not using FormBuilder, there are two ways to be notified of changes.

Method 1

As discussed in the comments on the question, use an event binding on each input element. Add to your template:

<input type="text" class="form-control" required [ngModel]="model.first_name"
         (ngModelChange)="doSomething($event)">

Then in your component:

doSomething(newValue) {
  model.first_name = newValue;
  console.log(newValue)
}

The Forms page has some additional information about ngModel that is relevant here:

The ngModelChange is not an <input> element event. It is actually an event property of the NgModel directive. When Angular sees a binding target in the form [(x)], it expects the x directive to have an x input property and an xChange output property.

The other oddity is the template expression, model.name = $event. We're used to seeing an $event object coming from a DOM event. The ngModelChange property doesn't produce a DOM event; it's an Angular EventEmitter property that returns the input box value when it fires..

We almost always prefer [(ngModel)]. We might split the binding if we had to do something special in the event handling such as debounce or throttle the key strokes.

In your case, I suppose you want to do something special.

Method 2

Define a local template variable and set it to ngForm.
Use ngControl on the input elements.
Get a reference to the form's NgForm directive using @ViewChild, then subscribe to the NgForm's ControlGroup for changes:

<form #myForm="ngForm" (ngSubmit)="onSubmit()">
  ....
  <input type="text" ngControl="firstName" class="form-control" 
   required [(ngModel)]="model.first_name">
  ...
  <input type="text" ngControl="lastName" class="form-control" 
   required [(ngModel)]="model.last_name">

class MyForm {
  @ViewChild('myForm') form;
  ...
  ngAfterViewInit() {
    console.log(this.form)
    this.form.control.valueChanges
      .subscribe(values => this.doSomething(values));
  }
  doSomething(values) {
    console.log(values);
  }
}

plunker

For more information on Method 2, see Savkin's video.

See also @Thierry's answer for more information on what you can do with the valueChanges observable (such as debouncing/waiting a bit before processing changes).

Just to clarify the best practice:

1. Text format messages should almost always be stored as TEXT (they end up being arbitrarily long)

2. String attributes should be stored as VARCHAR (the destination user name, the subject, etc...).

I understand that you've got a front end limit, which is great until it isn't. *grin* The trick is to think of the DB as separate from the applications that connect to it. Just because one application puts a limit on the data, doesn't mean that the data is intrinsically limited.

What is it about the messages themselves that forces them to never be more then 3000 characters? If it's just an arbitrary application constraint (say, for a text box or something), use a TEXT field at the data layer.

Try this

box:nth-child(3n) {  
     ...
}

DEMO

nth-child browser support

for python2, you can use this trick

def fun(a,b):
    return a+b

pool = multiprocessing.Pool(processes=6)
b=233
pool.map(lambda x:fun(x,b),range(1000))

If str.title() doesn't work for you, do the capitalization yourself.

1. Split the string into a list of words
2. Capitalize the first letter of each word
3. Join the words into a single string

One-liner:

>>> ' '.join([s[0].upper() + s[1:] for s in "they're bill's friends from the UK".split(' ')])
"They're Bill's Friends From The UK"

Clear example:

input = "they're bill's friends from the UK"
words = input.split(' ')
capitalized_words = []
for word in words:
    title_case_word = word[0].upper() + word[1:]
    capitalized_words.append(title_case_word)
output = ' '.join(capitalized_words)

Integer division truncates, so (50/100) results in 0. You can cast to float (better double) or multiply with 100.0 (for double precision, 100.0f for float precision) first,

double percentage;
// ...
percentage = 100.0*number/total;
// percentage = (double)number/total * 100;

or

float percentage;
// ...
percentage = (float)number/total * 100;
// percentage = 100.0f*number/total;

Since floating point arithmetic is not associative, the results of 100.0*number/total and (double)number/total * 100 may be slightly different (the same holds for float), but it's extremely unlikely to influence the first two places after the decimal point, so it probably doesn't matter which way you choose.

If you are to replace a fixed string or some pattern, I would also like to add the bash builtin pattern string replacement variable substitution construct. Instead of describing it myself, I am quoting the section from the bash manual:

${parameter/pattern/string}

The pattern is expanded to produce a pattern just as in pathname expansion. parameter is expanded and the longest match of pattern against its value is replaced with string. If pattern begins with /, all matches of pattern are replaced with string. Normally only the first match is replaced. If pattern begins with #, it must match at the beginning of the expanded value of parameter. If pattern begins with %, it must match at the end of the expanded value of parameter. If string is null, matches of pattern are deleted and the / following pattern may be omitted. If parameter is @ or *, the substitution operation is applied to each positional parameter in turn, and the expansion is the resultant list. If parameter is an array variable subscripted with @ or *, the substitution operation is applied to each member of the array in turn, and the expansion is the resultant list.

Here it goes.

// Select by value_x000D_
$('select[name="options"]').find('option[value="3"]').attr("selected",true);_x000D_
_x000D_
// Select by text_x000D_
//$('select[name="options"]').find('option:contains("Third")').attr("selected",true);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<html>_x000D_
<body>_x000D_
<select name="options">_x000D_
      <option value="1">First</option>_x000D_
      <option value="2">Second</option>_x000D_
      <option value="3">Third</option>_x000D_
</select>_x000D_
</body>_x000D_
</html>

You need to use the Scatter chart type instead of Line. That will allow you to define separate X values for each series.

Try this out. After going through a lot of posts and forums, I found this.

mWebView.setDownloadListener(new DownloadListener() {       

    @Override
    public void onDownloadStart(String url, String userAgent,
                                    String contentDisposition, String mimetype,
                                    long contentLength) {
            DownloadManager.Request request = new DownloadManager.Request(
                    Uri.parse(url));

            request.allowScanningByMediaScanner();
            request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); //Notify client once download is completed!
            request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "Name of your downloadble file goes here, example: Mathematics II ");
            DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
            dm.enqueue(request);
            Toast.makeText(getApplicationContext(), "Downloading File", //To notify the Client that the file is being downloaded
                    Toast.LENGTH_LONG).show();

        }
    });

Do not forget to give this permission! This is very important! Add this in your Manifest file(The AndroidManifest.xml file)

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />        <!-- for your file, say a pdf to work -->

Hope this helps. Cheers :)

Here's how you can do it with Java 8's Streams:

mySet.stream().sorted().collect(Collectors.toList());

or with a custom comparator:

mySet.stream().sorted(myComparator).collect(Collectors.toList());

Add overflow: auto; to the style and the two finger scroll should work.

I had a need to extract several cvs from different worksheets, so here is a modified version of plang code that allows you to specify the worksheet name.

if WScript.Arguments.Count < 3 Then
    WScript.Echo "Please specify the sheet, the source, the destination files. Usage: ExcelToCsv <sheetName> <xls/xlsx source file> <csv destination file>"
    Wscript.Quit
End If

csv_format = 6

Set objFSO = CreateObject("Scripting.FileSystemObject")

src_file = objFSO.GetAbsolutePathName(Wscript.Arguments.Item(1))
dest_file = objFSO.GetAbsolutePathName(WScript.Arguments.Item(2))

Dim oExcel
Set oExcel = CreateObject("Excel.Application")

Dim oBook
Set oBook = oExcel.Workbooks.Open(src_file)

oBook.Sheets(WScript.Arguments.Item(0)).Select
oBook.SaveAs dest_file, csv_format

oBook.Close False
oExcel.Quit

If $AccountNumber or $Balance is a node-set, then this behavior could easily happen. It's not because and is being treated as or.

For example, if $AccountNumber referred to nodes with the values 12345 and 66 and $Balance referred to nodes with the values 55 and 0, then $AccountNumber != '12345' would be true (because 66 is not equal to 12345) and $Balance != '0' would be true (because 55 is not equal to 0).

I'd suggest trying this instead:

<xsl:when test="not($AccountNumber = '12345' or $Balance = '0')">

$AccountNumber = '12345' or $Balance = '0' will be true any time there is an $AccountNumber with the value 12345 or there is a $Balance with the value 0, and if you apply not() to that, you will get a false result.

It can't be done directly, but you can emulate the same thing using function pointers and explicitly passing the "this" parameter:

typedef struct client_t client_t, *pno;
struct client_t
{
        pid_t pid;
        char password[TAM_MAX]; // -> 50 chars
        pno next;

        pno (*AddClient)(client_t *);    
};

pno client_t_AddClient(client_t *self) { /* code */ }

int main()
{

    client_t client;
    client.AddClient = client_t_AddClient; // probably really done in some init fn

    //code ..

    client.AddClient(&client);

}

It turns out that doing this, however, doesn't really buy you an awful lot. As such, you won't see many C APIs implemented in this style, since you may as well just call your external function and pass the instance.

Solution for CustomCell.selectionStyle = .none if you set some else style you saw "mixed" background color with gray or blue.

And don't forget! func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) didn't call when CustomCell.selectionStyle = .none.

extension MenuView: UITableViewDelegate {
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        let cellType = menuItems[indexPath.row]
        let selectedCell = tableView.cellForRow(at: indexPath)!
            selectedCell.contentView.backgroundColor = cellType == .none ? .clear : AppDelegate.statusbar?.backgroundColor?.withAlphaComponent(0.15)

        menuItemDidTap?(menuItems[indexPath.row])

        UIView.animate(withDuration: 0.15) {
            selectedCell.contentView.backgroundColor = .clear
        }
    }
}

Just create a graft of the parent of your new root commit to no parent (or to an empty commit, e.g. the real root commit of your repository). E.g. echo "<NEW-ROOT-SHA1>" > .git/info/grafts

After creating the graft, it takes effect right away; you should be able to look at git log and see that the unwanted old commits have gone away:

$ echo 4a46bc886318679d8b15e05aea40b83ff6c3bd47 > .git/info/grafts
$ git log --decorate | tail --lines=11

    Some message

If all looks as intended, you can just do a simple git filter-branch -- --all to make it permanent.

BEWARE: after doing the filter-branch step, all commit ids will have changed, so anybody using the old repo must never merge with anyone using the new repo.

I know there is an accepted answer but I recommend

Simple REST Client Extension for Chrome.

example:

Just use a related field without setting many=True.

Note that also because you want the output named category_name, but the actual field is category, you need to use the source argument on the serializer field.

The following should give you the output you need...

class ItemSerializer(serializers.ModelSerializer):
    category_name = serializers.RelatedField(source='category', read_only=True)

    class Meta:
        model = Item
        fields = ('id', 'name', 'category_name')

I'd try something like:

#!/usr/bin/python
from __future__ import print_function

import shlex
from subprocess import Popen, PIPE

def shlep(cmd):
    '''shlex split and popen
    '''
    parsed_cmd = shlex.split(cmd)
    ## if parsed_cmd[0] not in approved_commands:
    ##    raise ValueError, "Bad User!  No output for you!"
    proc = Popen(parsed_command, stdout=PIPE, stderr=PIPE)
    out, err = proc.communicate()
    return (proc.returncode, out, err)

... In other words let shlex.split() do most of the work. I would NOT attempt to parse the shell's command line, find pipe operators and set up your own pipeline. If you're going to do that then you'll basically have to write a complete shell syntax parser and you'll end up doing an awful lot of plumbing.

Of course this raises the question, why not just use Popen with the shell=True (keyword) option? This will let you pass a string (no splitting nor parsing) to the shell and still gather up the results to handle as you wish. My example here won't process any pipelines, backticks, file descriptor redirection, etc that might be in the command, they'll all appear as literal arguments to the command. Thus it is still safer then running with shell=True ... I've given a silly example of checking the command against some sort of "approved command" dictionary or set --- through it would make more sense to normalize that into an absolute path unless you intend to require that the arguments be normalized prior to passing the command string to this function.

If you are looking for delete cache of your own application then simply delete your cache directory and its all done !

public static void deleteCache(Context context) {
    try {
        File dir = context.getCacheDir();
        deleteDir(dir);
    } catch (Exception e) { e.printStackTrace();}
}

public static boolean deleteDir(File dir) {
    if (dir != null && dir.isDirectory()) {
        String[] children = dir.list();
        for (int i = 0; i < children.length; i++) {
            boolean success = deleteDir(new File(dir, children[i]));
            if (!success) {
                return false;
            }
        }
        return dir.delete();
    } else if(dir!= null && dir.isFile()) {
        return dir.delete();
    } else {
        return false;
    }
}

Maybe you can leverage the std::bitset type available in C++11. It can be used to represent a fixed sequence of N bits, which can be manipulated by conventional logic.

#include<iostream>
#include<bitset>

class MissileLauncher {
 public:
  MissileLauncher() {}
  void show_bits() const {
    std::cout<<m_abc[2]<<", "<<m_abc[1]<<", "<<m_abc[0]<<std::endl;
  }

  bool toggle_a() {
    // toggles (i.e., flips) the value of `a` bit and returns the
    // resulting logical value
    m_abc[0].flip();
    return m_abc[0];
  }

  bool toggle_c() {
    // toggles (i.e., flips) the value of `c` bit and returns the
    // resulting logical value
    m_abc[2].flip();
    return m_abc[2];
  }

  bool matches(const std::bitset<3>& mask) {
    // tests whether all the bits specified in `mask` are turned on in
    // this instance's bitfield
    return ((m_abc & mask) == mask);
  }

 private:
  std::bitset<3> m_abc;
};

typedef std::bitset<3> Mask;
int main() {
  MissileLauncher ml;

  // notice that the bitset can be "built" from a string - this masks
  // can be made available as constants to test whether certain bits
  // or bit combinations are "on" or "off"
  Mask has_a("001");       // the zeroth bit
  Mask has_b("010");       // the first bit
  Mask has_c("100");       // the second bit
  Mask has_a_and_c("101"); // zeroth and second bits
  Mask has_all_on("111");  // all on!
  Mask has_all_off("000"); // all off!

  // I can even create masks using standard logic (in this case I use
  // the or "|" operator)
  Mask has_a_and_b = has_a | has_b;
  std::cout<<"This should be 011: "<<has_a_and_b<<std::endl;

  // print "true" and "false" instead of "1" and "0"
  std::cout<<std::boolalpha;

  std::cout<<"Bits, as created"<<std::endl;
  ml.show_bits();
  std::cout<<"is a turned on? "<<ml.matches(has_a)<<std::endl;
  std::cout<<"I will toggle a"<<std::endl;
  ml.toggle_a();
  std::cout<<"Resulting bits:"<<std::endl;
  ml.show_bits();  
  std::cout<<"is a turned on now? "<<ml.matches(has_a)<<std::endl;
  std::cout<<"are both a and c on? "<<ml.matches(has_a_and_c)<<std::endl;
  std::cout<<"Toggle c"<<std::endl;
  ml.toggle_c();
  std::cout<<"Resulting bits:"<<std::endl;
  ml.show_bits();    
  std::cout<<"are both a and c on now? "<<ml.matches(has_a_and_c)<<std::endl;  
  std::cout<<"but, are all bits on? "<<ml.matches(has_all_on)<<std::endl;
  return 0;
}

Compiling using gcc 4.7.2

g++ example.cpp -std=c++11

I get:

This should be 011: 011
Bits, as created
false, false, false
is a turned on? false
I will toggle a
Resulting bits:
false, false, true
is a turned on now? true
are both a and c on? false
Toggle c
Resulting bits:
true, false, true
are both a and c on now? true
but, are all bits on? false

Latest Update: 16/01/2020

CSS Custom Properties (Variables) have arrived!

It's 2020 and time to officially roll out this feature in your new applications.

Preprocessor "NOT" required!

There is a lot of repetition in CSS. A single color may be used in several places.

For some CSS declarations, it is possible to declare this higher in the cascade and let CSS inheritance solve this problem naturally.

For non-trivial projects, this is not always possible. By declaring a variable on the :root pseudo-element, a CSS author can halt some instances of repetition by using the variable.

How it works

Set your variable at the top of your stylesheet:

CSS

Create a root class:

:root {
}

Create variables (-- [String] : [value])

:root {
  --red: #b00;
  --blue: #00b;
  --fullwidth: 100%;
}

Set your variables anywhere in your CSS document:

h1 {
  color: var(--red);
}
#MyText {
  color: var(--blue);
  width: var(--fullwidth);
}

TRY IT OUT

A fiddle and snippet are attached below for testing:

(It will only work with supported browsers.)

DEMO FIDDLE

:root {
  --red: #b00;
  --blue: #4679bd;
  --grey: #ddd;
  --W200: 200px;
  --Lft: left;
}
.Bx1,
.Bx2,
.Bx3,
.Bx4 {
  float: var(--Lft);
  width: var(--W200);
  height: var(--W200);
  margin: 10px;
  padding: 10px;
  border: 1px solid var(--red);
}
.Bx1 {
  color: var(--red);
  background: var(--grey);
}
.Bx2 {
  color: var(--grey);
  background: black;
}
.Bx3 {
  color: var(--grey);
  background: var(--blue);
}
.Bx4 {
  color: var(--grey);
  background: var(--red);
}

<p>If you see four square boxes then variables are working as expected.</p>

<div class="Bx1">I should be red text on grey background.</div>
<div class="Bx2">I should be grey text on black background.</div>
<div class="Bx3">I should be grey text on blue background.</div>
<div class="Bx4">I should be grey text on red background.</div>

The field identifiers are indeed C initializer syntax. In C++ just give the values in the correct order without the field names. Unfortunately this means you need to give them all (actually you can omit trailing zero-valued fields and the result will be the same):

address temp_address = { 0, 0, "Hamilton", "Ontario", 0 }; 

When you define a function, you also define what info (arguments) that function needs to work. If it is designed to work without any additional info, and you pass it some, you are going to get that error.

Example: Takes no arguments:

def dog
end

Takes arguments:

def cat(name)
end

When you call these, you need to call them with the arguments you defined.

dog                  #works fine
cat("Fluffy")        #works fine


dog("Fido")          #Returns ArgumentError (1 for 0)
cat                  #Returns ArgumentError (0 for 1)

Check out the Ruby Koans to learn all this.

Put the following code in your CSS, this works with Bootstrap 4:

.w-100 {
  width: 100% !important;
  height: 75vh;
}

You can use either = or "space". For instance following two commands return the same

git log --author="Developer1"

git log --author "Developer1"

My version use the first one, with some error checking...

BEGIN;
CREATE OR REPLACE FUNCTION reset_sequence(_table_schema text, _tablename text, _columnname text, _sequence_name text)
RETURNS pg_catalog.void AS
$BODY$
DECLARE
BEGIN
 PERFORM 1
 FROM information_schema.sequences
 WHERE
  sequence_schema = _table_schema AND
  sequence_name = _sequence_name;
 IF FOUND THEN
  EXECUTE 'SELECT setval( ''' || _table_schema || '.' || _sequence_name  || ''', ' || '(SELECT MAX(' || _columnname || ') FROM ' || _table_schema || '.' || _tablename || ')' || '+1)';
 ELSE
  RAISE WARNING 'SEQUENCE NOT UPDATED ON %.%', _tablename, _columnname;
 END IF;
END; 
$BODY$
 LANGUAGE 'plpgsql';

SELECT reset_sequence(table_schema, table_name, column_name, table_name || '_' || column_name || '_seq')
FROM information_schema.columns
WHERE column_default LIKE 'nextval%';

DROP FUNCTION reset_sequence(_table_schema text, _tablename text, _columnname text, _sequence_name text) ;
COMMIT;

The main difference is that the output of pip freeze can be dumped into a requirements.txt file and used later to re-construct the "frozen" environment.

In other words you can run: pip freeze > frozen-requirements.txt on one machine and then later on a different machine or on a clean environment you can do: pip install -r frozen-requirements.txt and you'll get the an identical environment with the exact same dependencies installed as you had in the original environment where you generated the frozen-requirements.txt.

Bootstrap 3

If you need to separate rows in bootstrap, you can simply use .form-group. This adds 15px margin to the bottom of row.

In your case, to get margin top, you can add this class to previous .row element

<div class="row form-group">

/* From bootstrap.css */
.form-group {
        margin-bottom: 15px;
}

Bootstrap 4

You can use built-in spacing classes

<div class="row mt-3"></div>

The "t" in class name makes it apply only to "top" side, there are similar classes for bottom, left, right. The number defines space size.

You can achieve your results with two methods:-

First Method define position values:-

HTML

 <ul>
 <li>Hello</li>
 <li>Hello world</li>
 </ul>

CSS

    ul{
    width:100px;    
}

ul li{
    border:1px solid orange;
    background: url("http://www.adaweb.net/Portals/0/Images/arrow1.gif") no-repeat 90% 5px;
}


ul li:hover{
    background: yellow url("http://www.adaweb.net/Portals/0/Images/arrow1.gif") no-repeat 90% 5px;
}

First Demo:- http://jsfiddle.net/QeGAd/18/

Second Method by CSS :before:after Selectors

HTML

<ul>
<li>Hello</li>
<li>Hello world</li>

CSS

    ul{
    width:100px;    
}

ul li{
    border:1px solid orange;
}

ul li:after {
    content: " ";
    padding-right: 16px;
    background: url("http://www.adaweb.net/Portals/0/Images/arrow1.gif") no-repeat center right;
}

ul li:hover {
    background:yellow;
}

ul li:hover:after {
    content: " ";
    padding-right: 16px;
    background: url("http://www.adaweb.net/Portals/0/Images/arrow1.gif") no-repeat center right;
}

Second Demo:- http://jsfiddle.net/QeGAd/17/

select Count(distinct columnName) as columnNameCount from tableName 

<input type="checkbox" checked="checked" />

or simply

<input type="checkbox" checked />

for checked checkbox. No checked attribute (<input type="checkbox" />) for unchecked checkbox.

reference: http://www.w3.org/TR/html-markup/input.checkbox.html#input.checkbox.attrs.checked

I don't know how Kosher it is, but I found that this scheme moves the ViewController's view down and provides the status bar with a solid background:

- (void)viewDidLoad {
    [super viewDidLoad];

    // Shove everything down if iOS 7 or later
    float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
    if (systemVersion >= 7.0f) {

        // Move the view down 20 pixels
        CGRect bounds = self.view.bounds;
        bounds.origin.y -= 20.0;
        [self.view setBounds:bounds];

        // Create a solid color background for the status bar
        CGRect statusFrame = CGRectMake(0.0, -20.0, bounds.size.width, 20);
        UIView* statusBar = [[UIView alloc] initWithFrame:statusFrame];
        statusBar.backgroundColor = [UIColor redColor];
        [self.view addSubview:statusBar];
    }

Of course, replace redColor with whatever color you want for the background.

You must separately do one of the swizzles to set the color of the characters/symbols in the status bar. I use View controller-based status bar appearance = NO and Status bar style = Opaque black style in the plist, to do this globally.

Seems to work, and I'd be interested to hear of any bugs or issues with it.

Instead:

public class PhotosFragment extends Fragment

You can use:

public class PhotosFragment extends ListFragment

It change the methods

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        ArrayList<ListviewContactItem> listContact = GetlistContact();
        setAdapter(new ListviewContactAdapter(getActivity(), listContact));
    }

onActivityCreated is void and you didn't need to return a view like in onCreateView

You can see an example here

Current Example:

You need to define border-width:1px

Your code should read:

$(this).css({"border-color": "#C1E0FF", 
             "border-width":"1px", 
             "border-style":"solid"});

Suggested Example:

You should ideally use a class and addClass/removeClass

$(this).addClass('borderClass'); $(this).removeClass('borderClass');

and in your CSS:

.borderClass{
  border-color: #C1E0FF;
  border-width:1px;
  border-style: solid;
  /** OR USE INLINE
  border: 1px solid #C1E0FF;
  **/
}

jsfiddle working example: http://jsfiddle.net/gorelative/tVbvF/\

jsfiddle with animate: http://jsfiddle.net/gorelative/j9Xxa/ This just gives you an example of how it could work, you should get the idea.. There are better ways of doing this most likely.. like using a toggle()

Just remember that modifying the padding or margins on any bootstrap grid elements is likely to create overflowing elements at some point at lower screen-widths.

If that happens just remember to use CSS media queries and only include the margins at screen-widths that can handle it.

In keeping with the mobile-first approach of the framework you are working within (bootstrap) it is better to add the padding at widths which can handle it, rather than excluding it at widths which can't.

@media (min-width: 992px){

Make sure that the -L option appears ahead of the -l option; the order of options in linker command lines does matter, especially with static libraries. The -L option specifies a directory to be searched for libraries (static or shared). The -lname option specifies a library which is with libmine.a (static) or libmine.so (shared on most variants of Unix, but Mac OS X uses .dylib and HP-UX used to use .sl). Conventionally, a static library will be in a file libmine.a. This is convention, not mandatory, but if the name is not in the libmine.a format, you cannot use the -lmine notation to find it; you must list it explicitly on the compiler (linker) command line.

The -L./libmine option says "there is a sub-directory called libmine which can be searched to find libraries". I can see three possibilities:

1. You have such a sub-directory containing libmine.a, in which case you also need to add -lmine to the linker line (after the object files that reference the library).
2. You have a file libmine that is a static archive, in which case you simply list it as a file ./libmine with no -L in front.
3. You have a file libmine.a in the current directory that you want to pick up. You can either write ./libmine.a or -L . -lmine and both should find the library.

Members must be resolvable at compile time to be called directly from C#. Otherwise you must use reflection or dynamic objects.

Reflection

namespace ConsoleApplication1
{
    using System;
    using System.Reflection;

    class Program
    {
        static void Main(string[] args)
        {
            var DLL = Assembly.LoadFile(@"C:\visual studio 2012\Projects\ConsoleApplication1\ConsoleApplication1\DLL.dll");

            foreach(Type type in DLL.GetExportedTypes())
            {
                var c = Activator.CreateInstance(type);
                type.InvokeMember("Output", BindingFlags.InvokeMethod, null, c, new object[] {@"Hello"});
            }

            Console.ReadLine();
        }
    }
}

Dynamic (.NET 4.0)

namespace ConsoleApplication1
{
    using System;
    using System.Reflection;

    class Program
    {
        static void Main(string[] args)
        {
            var DLL = Assembly.LoadFile(@"C:\visual studio 2012\Projects\ConsoleApplication1\ConsoleApplication1\DLL.dll");

            foreach(Type type in DLL.GetExportedTypes())
            {
                dynamic c = Activator.CreateInstance(type);
                c.Output(@"Hello");
            }

            Console.ReadLine();
        }
    }
}

If the icon is from Font Awesome (https://fontawesome.com/icons/) then you could tap into the color css property to change it's background.

fb-icon{
color:none;
}

fb-icon:hover{
color:#0000ff;
}

This is irrespective of the color it had. So you could use an entirely different color in its usual state and define another in its active state.

try this trick

div{
 -webkit-box-sizing: border-box; 
 -moz-box-sizing: border-box;    
 box-sizing: border-box;      
}

this will force the browser to calculate the width acording to the "outer"-width of the div, it means the padding will be substracted from the width.

This is the favicon and is explained in the link.

e.g. from W3C

  <link rel="icon" 
     type="image/png" 
     href="http://example.com/myicon.png">

Plus, of course the image file in the appropriate place.

Ignore the people that are suggesting that the property name is the issue. The jQuery API documentation explicitly states that either notation is acceptable: http://api.jquery.com/css/

The actual problem is that you are missing a closing curly brace on this line:

$("#myParagraph").css({"backgroundColor":"black","color":"white");

Change it to this:

$("#myParagraph").css({"backgroundColor": "black", "color": "white"});

Here's a working demo: http://jsfiddle.net/YPYz8/

$(init);_x000D_
    _x000D_
function init() {_x000D_
    $("h1").css("backgroundColor", "yellow");_x000D_
    $("#myParagraph").css({ "backgroundColor": "black", "color": "white" });_x000D_
    $(".bordered").css("border", "1px solid black");_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>_x000D_
<div class="bordered">_x000D_
    <h1>Header</h1>_x000D_
    <p id="myParagraph">This is some paragraph text</p>_x000D_
</div>

By using (,), you are capturing the group, if you simply remove them you will not have this problem.

>>> str1 = "a    b     c      d"
>>> re.split(" +", str1)
['a', 'b', 'c', 'd']

However there is no need for regex, str.split without any delimiter specified will split this by whitespace for you. This would be the best way in this case.

>>> str1.split()
['a', 'b', 'c', 'd']

If you really wanted regex you can use this ('\s' represents whitespace and it's clearer):

>>> re.split("\s+", str1)
['a', 'b', 'c', 'd']

or you can find all non-whitespace characters

>>> re.findall(r'\S+',str1)
['a', 'b', 'c', 'd']

This problem was due to the use of AngularJS 1.1.5 (which was unstable, and obviously had some bug or different implementation of the routing than it was in 1.0.7)

turning it back to 1.0.7 solved the problem instantly.

have tried the 1.2.0rc1 version, but have not finished testing as I had to rewrite some of the router functionality since they took it out of the core.

anyway, this problem is fixed when using AngularJS vs 1.0.7.

If you want to work with $?, you'll need to check it after each command, since $? is updated after each command exits. This means that if you execute a pipeline, you'll only get the exit code of the last process in the pipeline.

Another approach is to do this:

set -e
set -o pipefail

If you put this at the top of the shell script, it looks like Bash will take care of this for you. As a previous poster noted, "set -e" will cause Bash to exit with an error on any simple command. "set -o pipefail" will cause Bash to exit with an error on any command in a pipeline as well.

See here or here for a little more discussion on this problem. Here is the Bash manual section on the set builtin.

I had a case where the error was thrown by a

$state.go('');

Which is obvious. I guess this can help someone in future.

(DateTime.Parse((Eval("date").ToString()))).DayOfWeek.ToString()

at the place of Eval("date"),you can use any date...get name of day

Try something like this:

SELECT 
* 
FROM
(SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks) t1 
INNER JOIN
(SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks) t2
ON t1.ks = t2.ks

Yes it can. A private constructor would exist to prevent the class from being instantiated, or because construction happens only internally, e.g. a Factory pattern. See here for more information.

I think one of the Advantages of code first is that you can back up all the changes you've made to a version control system like Git. Because all your tables and relationships are stored in what are essentially just classes, you can go back in time and see what the structure of your database was before.

Building on top of @La masse's solution, but using autolayout to support rotation

Set anchors for the view's position (left, top, centerY, centerX, etc). You can also set the width anchor or set the frame.width dynamically with the UIScreen extension provided (to support rotation)

label = UILabel()
label.numberOfLines = 0
label.lineBreakMode = .byWordWrapping
self.view.addSubview(label)
// SET AUTOLAYOUT ANCHORS
label.translatesAutoresizingMaskIntoConstraints = false
label.leftAnchor.constraint(equalTo: self.view.leftAnchor, constant: 20).isActive = true
label.rightAnchor.constraint(equalTo: self.view.rightAnchor, constant: -20).isActive = true
label.topAnchor.constraint(equalTo: self.view.topAnchor, constant: 20).isActive = true
// OPTIONALLY, YOU CAN USE THIS INSTEAD OF THE WIDTH ANCHOR (OR LEFT/RIGHT)
// label.frame.size = CGSize(width: UIScreen.absoluteWidth() - 40.0, height: 0)
label.text = "YOUR LONG TEXT GOES HERE"
label.sizeToFit()

If setting frame.width dynamically using UIScreen:

extension UIScreen {   // OPTIONAL IF USING A DYNAMIC FRAME WIDTH
    class func absoluteWidth() -> CGFloat {
        var width: CGFloat
        if UIScreen.main.bounds.width > UIScreen.main.bounds.height {
            width = self.main.bounds.height // Landscape
        } else {
            width = self.main.bounds.width // Portrait
        }
        return width
    }
}

I am using an Apache vhost-File to run PHP with application-specific ini-options on my windows-server. Therefore I use the -d option of the php-command.

I am setting the open_basedir for every application as one of these options.

I needed to set multiple urls as open_basedir, including an UNC-Path, and the syntax for this case was a bit hard to find. You have to seperate the paths with semicolons and if your first path starts with a driveletter you might have to start the list with a semicolon too. At least that's what works for me.

Example:

php.exe -d open_basedir=;d:/www/applicationRoot;//internal.unc.path/ressource/

my 2c:

I tried both with n and with nvm on Linux Ubuntu 12.04 LTS, in order to update node from v0.8.25 to v0.10.22.

The first one was successfully completed, but the command 'which node' resulted in the old v0.8.25.
The second one was successfully completed and the same command resulted in v.0.10.22.

Use:

https://wa.me/YOURNUMBER

where YOURNUMBER is without the two leading 00.

For instance for +37061204312 you write:

https://wa.me/37061204312

This link seems to work on mobiles and on desktop computers.

To prefill the message with text you can use:

Using the example data set that Ananda dummied up, here's an example using aggregate(), which is part of core R. aggregate() just needs something to count as function of the different values of MONTH-YEAR. In this case, I used VALUE as the thing to count:

aggregate(cbind(count = VALUE) ~ MONTH.YEAR, 
          data = mydf, 
          FUN = function(x){NROW(x)})

which gives you..

  MONTH.YEAR count
1  FEB. 2012     2
2  JAN. 2012     2

Probably a bit late to answer this but I just found this thread and I had created my own code for it previously...

    list = [1,2,3,4,5]
    deleteList = []
    processNo = 0
    for item in list:
        if condition:
            print item
            deleteList.insert(0, processNo)
        processNo += 1

    if len(deleteList) > 0:
        for item in deleteList:
            del list[item]

It may be a long way of doing it but seems to work well. I create a second list that only holds numbers that relate to the list item to delete. Note the "insert" inserts the list item number at position 0 and pushes the remainder along so when deleting the items, the list is deleted from the highest number back to the lowest number so the list stays in sequence.

In my case there was a need for:

@Injectable({
    providedIn: 'root'  // <- ADD THIS
})
export class FooService { ...

instead of just:

@Injectable()
export class FooService { ...

If you define classproperty as follows, then your example works exactly as you requested.

class classproperty(object):
    def __init__(self, f):
        self.f = f
    def __get__(self, obj, owner):
        return self.f(owner)

The caveat is that you can't use this for writable properties. While e.I = 20 will raise an AttributeError, Example.I = 20 will overwrite the property object itself.

There is no command to do exactly what you asked.

Here are some close matches.

You can delete all the pods in a single namespace with this command:

kubectl delete --all pods --namespace=foo

You can also delete all deployments in namespace which will delete all pods attached with the deployments corresponding to the namespace

kubectl delete --all deployments --namespace=foo

You can delete all namespaces and every object in every namespace (but not un-namespaced objects, like nodes and some events) with this command:

kubectl delete --all namespaces

However, the latter command is probably not something you want to do, since it will delete things in the kube-system namespace, which will make your cluster not usable.

This command will delete all the namespaces except kube-system, which might be useful:

for each in $(kubectl get ns -o jsonpath="{.items[*].metadata.name}" | grep -v kube-system);
do
  kubectl delete ns $each
done

There's a short overview at MinGW-w64 Wiki:

Why doesn't mingw-w64 gcc support Dwarf-2 Exception Handling?

The Dwarf-2 EH implementation for Windows is not designed at all to work under 64-bit Windows applications. In win32 mode, the exception unwind handler cannot propagate through non-dw2 aware code, this means that any exception going through any non-dw2 aware "foreign frames" code will fail, including Windows system DLLs and DLLs built with Visual Studio. Dwarf-2 unwinding code in gcc inspects the x86 unwinding assembly and is unable to proceed without other dwarf-2 unwind information.

The SetJump LongJump method of exception handling works for most cases on both win32 and win64, except for general protection faults. Structured exception handling support in gcc is being developed to overcome the weaknesses of dw2 and sjlj. On win64, the unwind-information are placed in xdata-section and there is the .pdata (function descriptor table) instead of the stack. For win32, the chain of handlers are on stack and need to be saved/restored by real executed code.

GCC GNU about Exception Handling:

GCC supports two methods for exception handling (EH):

• DWARF-2 (DW2) EH, which requires the use of DWARF-2 (or DWARF-3) debugging information. DW-2 EH can cause executables to be slightly bloated because large call stack unwinding tables have to be included in th executables.
• A method based on setjmp/longjmp (SJLJ). SJLJ-based EH is much slower than DW2 EH (penalising even normal execution when no exceptions are thrown), but can work across code that has not been compiled with GCC or that does not have call-stack unwinding information.

[...]

Structured Exception Handling (SEH)

Windows uses its own exception handling mechanism known as Structured Exception Handling (SEH). [...] Unfortunately, GCC does not support SEH yet. [...]

See also:

• Exception handling models of GCC
• C++ Exception Handling for IA-64

Map<String, Integer> map = new HashMap<>();
map.put("test1", 1);
map.put("test2", 2);

Map<String, Integer> map2 = new HashMap<>();
map.forEach(map2::put);

System.out.println("map: " + map);
System.out.println("map2: " + map2);
// Output:
// map:  {test2=2, test1=1}
// map2: {test2=2, test1=1}

You can use the forEach method to do what you want.

What you're doing there is:

map.forEach(new BiConsumer<String, Integer>() {
    @Override
    public void accept(String s, Integer integer) {
        map2.put(s, integer);     
    }
});

Which we can simplify into a lambda:

map.forEach((s, integer) ->  map2.put(s, integer));

And because we're just calling an existing method we can use a method reference, which gives us:

map.forEach(map2::put);

I faced the same issue recently. I found a solution that apparently works for all devices. You can't do async focus programmatically but you can switch focus to your target input when some other input is already focused. So what you need to do is create, hide, append to DOM & focus a fake input on trigger event and, when the async action completes, just call focus again on the target input. Here's an example snippet - run it on your mobile.

edit:

Here's a fiddle with the same code. Apparently you can't run attached snippets on mobiles (or I'm doing something wrong).

<input type="text" onblur="if(this.value == '') this.value='SEARCH';" onfocus="if(this.value == 'SEARCH') this.value='';" size="15" value="SEARCH" name="xSearch" id="xSearch">

Or this for textarea?

<textarea id="usermsg" rows="2" cols="70" onfocus="if(this.value == 'enter your text here') this.value='';" onblur="if(this.value == '') this.value='enter your text here';" >enter your text here</textarea>

select t1.Column as Price, t2.Column as Other_Price
from table1 as t1 INNER JOIN table2 as t2 
ON t1.Key = t2.Key 

like this ?

If you want to avoid changing syntax to solve this problem, try this:

Update your MySQL to version 5.5 or greater.

This resolved the problem for me.

A File object in Java is a representation of a path to a directory or file, not the file itself. You don't need to have write access to the filesystem to create a File object, you only need it if you intend to actually write to the file (using a FileOutputStream for example)

I have applications that use both Java 7 and 8 and have to go back and forth all the time.

Updated recommendation!!:

Use jenv https://www.jenv.be/ and homebrew.

Then its just jenv global oracle6401.6.0.39 and its set.

Here is my short implementation, please criticize or improve it!

public class ConcurrentLRUCache<Key, Value> {

private final int maxSize;
private int currentSize = 0;

private ConcurrentHashMap<Key, Value> map;

public ConcurrentLRUCache(final int maxSize) {
    this.maxSize = maxSize;
    map = new ConcurrentHashMap<Key, Value>(maxSize);
    queue = new ConcurrentLinkedQueue<Key>();
}

private synchronized void freeSpace() {
    Key key = queue.poll();
    if (null != key) {
        map.remove(key);
        currentSize = map.size();
    }
}

public void put(Key key, Value val) {
    if (map.containsKey(key)) {// just heat up that item
        put(key, val);
        return;
    }
    while (currentSize >= maxSize) {
        freeSpace();
    }
    synchronized(this) {
        queue.add(key);
        map.put(key, val);

}

public Value get(Key key) {
    return map.get(key);

It means that you should not share an iterator object among multiple threads. Creating multiple iterators and using them concurrently in separate threads is fine.

//Set time zone
date_default_timezone_set("asia/kolkata");
$pastdate='2016-07-20';
$addYear=1;
$addMonth=3;
$addWeek=2;
$addDays=5;
$newdate=date('Y-m-d', strtotime($pastdate.' +'.$addYear.' years +'.$addMonth. ' months +'.$addWeek.' weeks +'.$addDays.' days'));
echo $newdate;

Since there is no issue with GC. I prefer this.

for(int i=0; i<array.length; ++i){
    if(array[i] == valueToFind)
        return true;
}

Each version of Visual Studio prior to Visual Studio 2010 is tied to a specific .NET framework. (VS2008 is .NET 3.5, VS2005 is .NET 2.0, VS2003 is .NET1.1) Visual Studio 2010 and beyond allow for targeting of prior framework versions but cannot be used for future releases. You must use Visual Studio 2012 in order to utilize .NET 4.5.

On Windows 2003, to call another script without waiting, I used this:

$commandString = "start /b c:\\php\\php.EXE C:\\Inetpub\\wwwroot\\mysite.com\\phpforktest.php --passmsg=$testmsg"; 
pclose(popen($commandString, 'r'));

This only works AFTER giving changing permissions on cmd.exe - add Read and Execute for IUSR_YOURMACHINE (I also set write to Deny).

Here is a solution using traditional graphics (and Dirk's data):

> DF <- data.frame(x=1:10, y=rnorm(10)+5, z=sample(letters[1:3], 10, replace=TRUE)) 
> DF
    x        y z
1   1 6.628380 c
2   2 6.403279 b
3   3 6.708716 a
4   4 7.011677 c
5   5 6.363794 a
6   6 5.912945 b
7   7 2.996335 a
8   8 5.242786 c
9   9 4.455582 c
10 10 4.362427 a
> attach(DF); plot(x, y, col=c("red","blue","green")[z]); detach(DF)

This relies on the fact that DF$z is a factor, so when subsetting by it, its values will be treated as integers. So the elements of the color vector will vary with z as follows:

> c("red","blue","green")[DF$z]
 [1] "green" "blue"  "red"   "green" "red"   "blue"  "red"   "green" "green" "red"    

You can add a legend using the legend function:

legend(x="topright", legend = levels(DF$z), col=c("red","blue","green"), pch=1)

Based on generality of this question, I think, that you'll need to setup your own HTTPS proxy on some server online. Do the following steps:

• Prepare your proxy server - install IIS, Apache
• Get valid SSL certificate to avoid security errors (free from startssl.com for example)
• Write a wrapper, which will download insecure content (how to below)
• From your site/app get https://yourproxy.com/?page=http://insecurepage.com

If you simply download remote site content via file_get_contents or similiar, you can still have insecure links to content. You'll have to find them with regex and also replace. Images are hard to solve, but Ï found workaround here: http://foundationphp.com/tutorials/image_proxy.php

Note: While this solution may have worked in some browsers when it was written in 2014, it no longer works. Navigating or redirecting to an HTTP URL in an iframe embedded in an HTTPS page is not permitted by modern browsers, even if the frame started out with an HTTPS URL.

The best solution I created is to simply use google as the ssl proxy...

https://www.google.com/search?q=%http://yourhttpsite.com&btnI=Im+Feeling+Lucky

Tested and works in firefox.

Other Methods:

• Use a Third party such as embed.ly (but it it really only good for well known http APIs).

• Create your own redirect script on an https page you control (a simple javascript redirect on a relative linked page should do the trick. Something like: (you can use any langauge/method)

  https://example.com That has a iframe linking to...

  https://example.com/utilities/redirect.html Which has a simple js redirect script like...

  document.location.href ="http://thenonsslsite.com";

• Alternatively, you could add an RSS feed or write some reader/parser to read the http site and display it within your https site.

• You could/should also recommend to the http site owner that they create an ssl connection. If for no other reason than it increases seo.

Unless you can get the http site owner to create an ssl certificate, the most secure and permanent solution would be to create an RSS feed grabing the content you need (presumably you are not actually 'doing' anything on the http site -that is to say not logging in to any system).

The real issue is that having http elements inside a https site represents a security issue. There are no completely kosher ways around this security risk so the above are just current work arounds.

Note, that you can disable this security measure in most browsers (yourself, not for others). Also note that these 'hacks' may become obsolete over time.

If you just want to set the source of the image you can use this.

$("img").attr('src','http://somedomain.com/image.jpg');

You can use the easier function preg_match instead, It's better and faster than all of the other ones.

$var = "<tag>Get this var</tag>";
preg_match("/<tag>(.*)<\/tag>/", $var , $new_var);
echo $new_var['1']; 

Output: Get this var

We also need to mention default schema for SQSERVER: dbo

<property name="hibernate.default_schema">dbo</property>

All you need to do is use the file object as an iterator.

for line in open("log.txt"):
    do_something_with(line)

Even better is using context manager in recent Python versions.

with open("log.txt") as fileobject:
    for line in fileobject:
        do_something_with(line)

This will automatically close the file as well.

I don't really understand why you would make this an HTML Helper. I would make it part of the ViewData dictionary in an action method of the controller. Something like this:

ViewData["Age"] = DateTime.Now.Year - birthday.Year;

Given that birthday is passed into an action method and is a DateTime object.

Consider this code,

int some_int = 100;

while(some_int == 100)
{
   //your code
}

When this program gets compiled, the compiler may optimize this code, if it finds that the program never ever makes any attempt to change the value of some_int, so it may be tempted to optimize the while loop by changing it from while(some_int == 100) to something which is equivalent to while(true) so that the execution could be fast (since the condition in while loop appears to be true always). (if the compiler doesn't optimize it, then it has to fetch the value of some_int and compare it with 100, in each iteration which obviously is a little bit slow.)

However, sometimes, optimization (of some parts of your program) may be undesirable, because it may be that someone else is changing the value of some_int from outside the program which compiler is not aware of, since it can't see it; but it's how you've designed it. In that case, compiler's optimization would not produce the desired result!

So, to ensure the desired result, you need to somehow stop the compiler from optimizing the while loop. That is where the volatile keyword plays its role. All you need to do is this,

volatile int some_int = 100; //note the 'volatile' qualifier now!

In other words, I would explain this as follows:

volatile tells the compiler that,

"Hey compiler, I'm volatile and, you know, I can be changed by some XYZ that you're not even aware of. That XYZ could be anything. Maybe some alien outside this planet called program. Maybe some lightning, some form of interrupt, volcanoes, etc can mutate me. Maybe. You never know who is going to change me! So O you ignorant, stop playing an all-knowing god, and don't dare touch the code where I'm present. Okay?"

Well, that is how volatile prevents the compiler from optimizing code. Now search the web to see some sample examples.

Quoting from the C++ Standard ($7.1.5.1/8)

[..] volatile is a hint to the implementation to avoid aggressive optimization involving the object because the value of the object might be changed by means undetectable by an implementation.[...]

Related topic:

Does making a struct volatile make all its members volatile?

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

In order to take advantage of the auto-incrementing capability of the column, do not supply a value for that column when inserting rows. The database will supply a value for you.

INSERT INTO test.authors (
   instance_id,host_object_id,check_type,is_raw_check,
   current_check_attempt,max_check_attempts,state,state_type,
   start_time,start_time_usec,end_time,end_time_usec,command_object_id,
   command_args,command_line,timeout,early_timeout,execution_time,
   latency,return_code,output,long_output,perfdata
) VALUES (

   '0.102','1','PING WARNING -DUPLICATES FOUND! Packet loss = 0%, RTA = 2.86 ms',

);

As other answers pointed out, the following shortcuts are defined by default (I'm referring to editing java source - shortcut bindings can be found in eclipse Window>Preferences, under 'General'/'Keys', search for 'comment'):

• to add a block comment, the shortcut (binding) is: Ctrl + Shift + /
• to remove a block comment, the shortcut (binding) is: Ctrl + Shift + \

Unfortunately, these shortcuts did not work for me (on Eclipse Java EE IDE for Web Developers, version: Juno Service Release 2).

The reason, I think, is my keyboard layout (QWERTZ keyboard layout used in Germany - see here for further information), where '/' actually has to be written via 'Shift + 7'.

I therefore had to change the shortcut bindings for comments (just did it for editing java source) in the eclipse preferences (under 'General'/'Keys') as follows:

• Change the binding of command 'Add Block Comment' (when 'Editing Java Source') from 'Ctrl + Shift + /' to 'Ctrl + Shift + 7'
• Change the binding of command 'Remove Block Comment' (when 'Editing Java Source') from 'Ctrl + Shift + \' to 'Ctrl + Shift + 8'
• Unbind the binding 'Ctrl + /' for command 'Toggle Comment' (when 'Editing Java Source'); instead of assigning a new binding, I simply unbound this shortcut, as there already was one with Ctrl+7 and one with Ctrl+Shift+C (which both work for me)

I just fix this problem in my project-

I would not store the password hashed in two different ways, because then the system is at least as weak as the weakest of the hash algorithms in use.

You can use something like this:

for i in `cat foo.txt`
do
    sudo $i
done

Though if the commands have arguments (i.e. there is whitespace in the lines) you may have to monkey around with that a bit to protect the whitepace so that the whole string is seen by sudo as a command. But it gives you an idea on how to start.

How about str.gsub("subString", "") Check out the Ruby Doc

(Edited.) There are two reasons why it doesn't compile: You're missing a semi-colon at the end of this statement:

array3[i]=e1

Also the findOut method doesn't return any value if the array length is 0. Adding a return 0; at the end of the method will make it compile. I've no idea if that will make it do what you want though, as I've no idea what you want it to do.

Try this one, this one works best to suffice the requiremnt.

There are three packagers, and two compilers:

free packager: PAR
commercial packagers: perl2exe, perlapp
compilers: B::C, B::CC

http://search.cpan.org/dist/B-C/perlcompile.pod

(Note: perlfaq3 is still wrong)

For strawberry you need perl-5.16 and B-C from git master (1.43), as B-C-1.42 does not support 5.16.

Upcoming pandas 0.13 version will allow to add rows through loc on non existing index data. However, be aware that under the hood, this creates a copy of the entire DataFrame so it is not an efficient operation.

Description is here and this new feature is called Setting With Enlargement.

A null value cannot be assigned to a primitive type, like int, long, boolean, etc. If the database column that corresponds to the field in your object can be null, then your field should be a wrapper class, like Integer, Long, Boolean, etc.

The danger is that your code will run fine if there are no nulls in the DB, but will fail once nulls are inserted.

And you can always return the primitive type from the getter. Ex:

  private Integer num;

  public void setNum(Integer i) {
    this.num = i;
  }

  public int getNum() {
    return this.num;
  }

But in most cases you will want to return the wrapper class.

So either set your DB column to not allow nulls, or use a wrapper class.

I was referring to one of my provider with two different casing. One of them was wrong but only the webpack compiler was complaining. I had to step into the ClientApp folder and use ng build or ng serve to see the errors. (ASP.NET Core SPA with Angular 5)

Just hold cursor over member you interested in, and see tooltip - it will show memeber's type:

Well, it doesn't get much better than that. Officially, you should use

dataGridView1.DataSource = typeof(List); 
dataGridView1.DataSource = itemStates;

It's still a "clear/reset source" kind of solution, but I have yet to find anything else that would reliably refresh the DGV data source.

Edited

ES6 solution:

[...new Set(a)];

Alternative:

Array.from(new Set(a));

Old response. O(n^2) (do not use it with large arrays!)

var arrayUnique = function(a) {
    return a.reduce(function(p, c) {
        if (p.indexOf(c) < 0) p.push(c);
        return p;
    }, []);
};

In JavaScript you can do this:

const x = 'some string';_x000D_
console.log(x.substring(0, 1));

I would like to share something different, an extension to this topic.

Sometimes you want a "task promise" to be automatically re-created at the same address (property or variable) when it resolves. It's possible to create an outside resolver that does just that.

Example of a recurring promise with an external resolver. Whenever the resolver is called, a new promise is created at the same address/variable/property.

let resolvePromise;
let thePromise;

const setPromise = (resolve) => {
  resolvePromise = () => {
    resolve();
    thePromise = new Promise(setPromise);   
  }
}
thePromise = new Promise(setPromise);

(async () => {
  let i = 0;
  while (true) {
    let msg = (i % 2 === 0) ? 'Tick' : 'Tock';
    document.body.innerHTML = msg;
    setTimeout(resolvePromise, 1000);
    await thePromise;
    i++;
  }
})();

This forum on MSDN tells you.

Form.Close() sends the proper Windows messages to shut down the win32 window. During that process, if the form was not shown modally, Dispose is called on the form. Disposing the form frees up the unmanaged resources that the form is holding onto.

If you do a form1.Show() or Application.Run(new Form1()), Dispose will be called when Close() is called.

However, if you do form1.ShowDialog() to show the form modally, the form will not be disposed, and you'll need to call form1.Dispose() yourself. I believe this is the only time you should worry about disposing the form yourself.

2019 Update

The current answers and the official documentation are outdated. And for those new to TypeScript, the terminology used isn't clear without examples. Below is a list of up-to-date differences.

1. Objects / Functions

Both can be used to describe the shape of an object or a function signature. But the syntax differs.

Interface

interface Point {
  x: number;
  y: number;
}

interface SetPoint {
  (x: number, y: number): void;
}

Type alias

type Point = {
  x: number;
  y: number;
};

type SetPoint = (x: number, y: number) => void;

2. Other Types

Unlike an interface, the type alias can also be used for other types such as primitives, unions, and tuples.

// primitive
type Name = string;

// object
type PartialPointX = { x: number; };
type PartialPointY = { y: number; };

// union
type PartialPoint = PartialPointX | PartialPointY;

// tuple
type Data = [number, string];

3. Extend

Both can be extended, but again, the syntax differs. Additionally, note that an interface and type alias are not mutually exclusive. An interface can extend a type alias, and vice versa.

Interface extends interface

interface PartialPointX { x: number; }
interface Point extends PartialPointX { y: number; }

Type alias extends type alias

type PartialPointX = { x: number; };
type Point = PartialPointX & { y: number; };

Interface extends type alias

type PartialPointX = { x: number; };
interface Point extends PartialPointX { y: number; }

Type alias extends interface

interface PartialPointX { x: number; }
type Point = PartialPointX & { y: number; };

4. Implements

A class can implement an interface or type alias, both in the same exact way. Note however that a class and interface are considered static blueprints. Therefore, they can not implement / extend a type alias that names a union type.

interface Point {
  x: number;
  y: number;
}

class SomePoint implements Point {
  x = 1;
  y = 2;
}

type Point2 = {
  x: number;
  y: number;
};

class SomePoint2 implements Point2 {
  x = 1;
  y = 2;
}

type PartialPoint = { x: number; } | { y: number; };

// FIXME: can not implement a union type
class SomePartialPoint implements PartialPoint {
  x = 1;
  y = 2;
}

5. Declaration merging

Unlike a type alias, an interface can be defined multiple times, and will be treated as a single interface (with members of all declarations being merged).

// These two declarations become:
// interface Point { x: number; y: number; }
interface Point { x: number; }
interface Point { y: number; }

const point: Point = { x: 1, y: 2 };

Remember, Objective-C is a superset of C, so typecasting works as it does in C:

myEditController = [[SelectionListViewController alloc] init];
((SelectionListViewController *)myEditController).list = listOfItems;

To make the images flexible, simply add max-width:100% and height:auto. Image max-width:100% and height:auto works in IE7, but not in IE8 (yes, another weird IE bug). To fix this, you need to add width:auto\9 for IE8.

source: http://webdesignerwall.com/tutorials/responsive-design-with-css3-media-queries

for example :

img {
    max-width: 100%;
    height: auto;
    width: auto\9; /* ie8 */
}

and then any images you add simply using the img tag will be flexible

JSFiddle example here. No JavaScript required. Works in latest versions of Chrome, Firefox and IE (which is all I've tested).

The classic response is, "You don't." You test the public API of Foo, not its internals.

Is there any behavior of the Foo object (or, less good, some other object in the environment) that is affected by foo()? If so, test that. And if not, what does the method do?

// assuming driver is a healthy WebDriver instance
WebElement fileInput = driver.findElement(By.name("uploadfile"));
fileInput.sendKeys("C:/path/to/file.jpg");

Hey, that's mine from somewhere :).

In case of the Zamzar web, it should work perfectly. You don't click the element. You just type the path into it. To be concrete, this should be absolutely ok:

driver.findElement(By.id("inputFile")).sendKeys("C:/path/to/file.jpg");

In the case of the Uploadify web, you're in a pickle, since the upload thing is no input, but a Flash object. There's no API for WebDriver that would allow you to work with browser dialogs (or Flash objects).

So after you click the Flash element, there'll be a window popping up that you'll have no control over. In the browsers and operating systems I know, you can pretty much assume that after the window has been opened, the cursor is in the File name input. Please, make sure this assumption is true in your case, too.

If not, you could try to jump to it by pressing Alt + N, at least on Windows...

If yes, you can "blindly" type the path into it using the Robot class. In your case, that would be something in the way of:

driver.findElement(By.id("SWFUpload_0")).click();
Robot r = new Robot();
r.keyPress(KeyEvent.VK_C);        // C
r.keyRelease(KeyEvent.VK_C);
r.keyPress(KeyEvent.VK_COLON);    // : (colon)
r.keyRelease(KeyEvent.VK_COLON);
r.keyPress(KeyEvent.VK_SLASH);    // / (slash)
r.keyRelease(KeyEvent.VK_SLASH);
// etc. for the whole file path

r.keyPress(KeyEvent.VK_ENTER);    // confirm by pressing Enter in the end
r.keyRelease(KeyEvent.VK_ENTER);

It sucks, but it should work. Note that you might need these: How can I make Robot type a `:`? and Convert String to KeyEvents (plus there is the new and shiny KeyEvent#getExtendedKeyCodeForChar() which does similar work, but is available only from JDK7).

For Flash, the only alternative I know (from this discussion) is to use the dark technique:

First, you modify the source code of you the flash application, exposing internal methods using the ActionScript's ExternalInterface API. Once exposed, these methods will be callable by JavaScript in the browser.

Second, now that JavaScript can call internal methods in your flash app, you use WebDriver to make a JavaScript call in the web page, which will then call into your flash app.

This technique is explained further in the docs of the flash-selenium project. (http://code.google.com/p/flash-selenium/), but the idea behind the technique applies just as well to WebDriver.

You can use the IndexOf method and the Substring method like so:

string output = input.Substring(input.IndexOf('.') + 1);

The above doesn't have error handling, so if a period doesn't exist in the input string, it will present problems.

See perldoc/perlfaq:

Remember that int() merely truncates toward 0. For rounding to a certain number of digits, sprintf() or printf() is usually the easiest route.

 printf("%.3f",3.1415926535);
 # prints 3.142

The POSIX module (part of the standard Perl distribution) implements ceil(), floor(), and a number of other mathematical and trigonometric functions.

use POSIX;
$ceil  = ceil(3.5); # 4
$floor = floor(3.5); # 3

In 5.000 to 5.003 perls, trigonometry was done in the Math::Complex module.

With 5.004, the Math::Trig module (part of the standard Perl distribution) > implements the trigonometric functions.

Internally it uses the Math::Complex module and some functions can break out from the real axis into the complex plane, for example the inverse sine of 2.

Rounding in financial applications can have serious implications, and the rounding method used should be specified precisely. In these cases, it probably pays not to trust whichever system rounding is being used by Perl, but to instead implement the rounding function you need yourself.

To see why, notice how you'll still have an issue on half-way-point alternation:

for ($i = 0; $i < 1.01; $i += 0.05)
{
   printf "%.1f ",$i
}

0.0 0.1 0.1 0.2 0.2 0.2 0.3 0.3 0.4 0.4 0.5 0.5 0.6 0.7 0.7 0.8 0.8 0.9 0.9 1.0 1.0

Don't blame Perl. It's the same as in C. IEEE says we have to do this. Perl numbers whose absolute values are integers under 2**31 (on 32 bit machines) will work pretty much like mathematical integers. Other numbers are not guaranteed.

The new node is always added after the last node of the given Linked List. For example if the given Linked List is 5->10->15->20->25 and we add an item 30 at the end, then the Linked List becomes 5->10->15->20->25->30. Since a Linked List is typically represented by the head of it, we have to traverse the list till end and then change the next of last node to new node.

/* Given a reference (pointer to pointer) to the head
   of a list and an int, appends a new node at the end  */


    void append(struct node** head_ref, int new_data)
    {
    /* 1. allocate node */
         struct node* new_node = (struct node*) malloc(sizeof(struct node));

        struct node *last = *head_ref;  /* used in step 5*/

    /* 2. put in the data  */
        new_node->data  = new_data;

    /* 3. This new node is going to be the last node, so make next 
          of it as NULL*/
        new_node->next = NULL;

    /* 4. If the <a href="#">Linked List</a> is empty, then make the new node as head */
        if (*head_ref == NULL)
        {
       *head_ref = new_node;
       return;
        }  

    /* 5. Else traverse till the last node */
        while (last->next != NULL)
        last = last->next;

    /* 6. Change the next of last node */
        last->next = new_node;
        return;    
}

Addition to BeNdErR's answer:
The "other TEXT" element should have float:none, like:

    <div style="width:100%;">_x000D_
        <div style="float:left;width:30%; background:red;">...something something something  random text</div>_x000D_
        <div style="float:none; background:yellow;"> text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text  </div>_x000D_
    </div>

Without BOOST, directly using key and value

for(auto const& [key, value]: m_map)
    {
    std::cout<<" key="<<key;
    std::cout<<" value="<<value<<std::endl;
    }

Normally Python throws NameError if the variable is not defined:

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

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

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

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

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

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

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

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

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

The one answer that actually worked to fix this I found here: https://stackoverflow.com/a/18938991/550975

Just add this to your web.config:

<configuration>  
  <system.webServer>  
    <httpErrors existingResponse="PassThrough"/>  
  </system.webServer>  
<configuration>

It's a reserved keyword (like return, filter, function, break).

Reference

Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:

But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.

Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:

PS C:\> function ex{exit}
PS C:\> new-alias ^D ex

Note This is an improvement in @user3516549 answer and I have check it on Moto G3 with Android 6.0.1
I have this issue so I have tried answer of @user3516549 but in some cases it was not working properly. I have found that in Android 6.0(or above) when we start gallery image pick intent then a screen will open that shows recent images when user select image from this list we will get uri as

content://com.android.providers.media.documents/document/image%3A52530

while if user select gallery from sliding drawer instead of recent then we will get uri as

content://media/external/images/media/52530

So I have handle it in getRealPathFromURI_API19()

public static String getRealPathFromURI_API19(Context context, Uri uri) {
        String filePath = "";
        if (uri.getHost().contains("com.android.providers.media")) {
            // Image pick from recent 
            String wholeID = DocumentsContract.getDocumentId(uri);

            // Split at colon, use second item in the array
            String id = wholeID.split(":")[1];

            String[] column = {MediaStore.Images.Media.DATA};

            // where id is equal to
            String sel = MediaStore.Images.Media._ID + "=?";

            Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                    column, sel, new String[]{id}, null);

            int columnIndex = cursor.getColumnIndex(column[0]);

            if (cursor.moveToFirst()) {
                filePath = cursor.getString(columnIndex);
            }
            cursor.close();
            return filePath;
        } else {
            // image pick from gallery 
           return  getRealPathFromURI_BelowAPI11(context,uri)
        }

    }

EDIT1 : if you are trying to get image path of file in external sdcard in higher version then check my question

EDIT2 Here is complete code with handling virtual files and host other than com.android.providers I have tested this method with content://com.adobe.scan.android.documents/document/

In MySQL Workbench 6.1.

I had to click on the Apply changes button in the insertion panel (only once, because twice and MWB crashes...).

You have to do it for each of your table.

Then export your schema :

Check Generate INSERT statements for table

It is okay !

Node > 10.12.0

fs.mkdir now accepts a { recursive: true } option like so:

// Creates /tmp/a/apple, regardless of whether `/tmp` and /tmp/a exist.
fs.mkdir('/tmp/a/apple', { recursive: true }, (err) => {
  if (err) throw err;
});

or with a promise:

fs.promises.mkdir('/tmp/a/apple', { recursive: true }).catch(console.error);

Node <= 10.11.0

You can solve this with a package like mkdirp or fs-extra. If you don't want to install a package, please see Tiago Peres França's answer below.

You're looking for axhline (a horizontal axis line). For example, the following will give you a horizontal line at y = 0.5:

import matplotlib.pyplot as plt
plt.axhline(y=0.5, color='r', linestyle='-')
plt.show()

A cleaner representation of what some other answers have hinted at:

DELETE sourceTable
OUTPUT DELETED.*
INTO destTable (Comma, separated, list, of, columns)
WHERE <conditions (if any)>

It's still valid to use IE=edge,chrome=1.

But, since the chrome frame project has been wound down the chrome=1 part is redundant for browsers that don't already have the chrome frame plug in installed.

I use the following for correctness nowadays

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

After searching for an hour or two ,I've found a simple solution below.

const date = new Date(`${date from client} GMT`);

inside double ticks, there is a date from client side plust GMT.

I'm first time commenting, constructive criticism will be welcomed.

I think Lifecycle state can help to prevent such crash starting from Android support lib v26.1.0 you can have the following check:

if (getLifecycle().getCurrentState().isAtLeast(Lifecycle.State.STARTED)){
  // Do fragment's transaction commit
}

or you can try:

Fragment.isStateSaved()

Here is an expanded answer. A DecoratedBox is what you need to add a border, but I am using a Container for the convenience of adding margin and padding.

Here is the general setup.

Widget myWidget() {
  return Container(
    margin: const EdgeInsets.all(30.0),
    padding: const EdgeInsets.all(10.0),
    decoration: myBoxDecoration(), //             <--- BoxDecoration here
    child: Text(
      "text",
      style: TextStyle(fontSize: 30.0),
    ),
  );
}

where the BoxDecoration is

BoxDecoration myBoxDecoration() {
  return BoxDecoration(
    border: Border.all(),
  );
}

Border width

These have a border width of 1, 3, and 10 respectively.

BoxDecoration myBoxDecoration() {
  return BoxDecoration(
    border: Border.all(
      width: 1, //                   <--- border width here
    ),
  );
}

Border color

These have a border color of

• Colors.red
• Colors.blue
• Colors.green

Code

BoxDecoration myBoxDecoration() {
  return BoxDecoration(
    border: Border.all(
      color: Colors.red, //                   <--- border color
      width: 5.0,
    ),
  );
}

Border side

These have a border side of

• left (3.0), top (3.0)
• bottom (13.0)
• left (blue[100], 15.0), top (blue[300], 10.0), right (blue[500], 5.0), bottom (blue[800], 3.0)

Code

BoxDecoration myBoxDecoration() {
  return BoxDecoration(
    border: Border(
      left: BorderSide( //                   <--- left side
        color: Colors.black,
        width: 3.0,
      ),
      top: BorderSide( //                    <--- top side
        color: Colors.black,
        width: 3.0,
      ),
    ),
  );
}

Border radius

These have border radii of 5, 10, and 30 respectively.

BoxDecoration myBoxDecoration() {
  return BoxDecoration(
    border: Border.all(
      width: 3.0
    ),
    borderRadius: BorderRadius.all(
        Radius.circular(5.0) //                 <--- border radius here
    ),
  );
}

Going on

DecoratedBox/BoxDecoration are very flexible. Read Flutter — BoxDecoration Cheat Sheet for many more ideas.

I would do something like this:

function getCookie(cookie){
  return cookie
    .trim()
    .split(';')
    .map(function(line){return line.split(',');})
    .reduce(function(props,line) {
      var name = line[0].slice(0,line[0].search('='));
      var value = line[0].slice(line[0].search('='));
      props[name] = value;
      return props;
    },{})
}

This will return your cookie as an object.

And then you can call it like this:

getCookie(document.cookie)['shares']

echo Yii::$app->request->url;

You can use a single quote to access the key that you set in your Java program.

If you set a Map in Java like this

Map<String,Object> hash = new HashMap<String,Object>();
hash.put("firstname", "a");
hash.put("lastname", "b");

Map<String,Object> map = new HashMap<String,Object>();
map.put("hash", hash);

Then you can access the members of 'hash' in Freemarker like this -

${hash['firstname']}
${hash['lastname']}

Output :

a
b

int main()
{
  int size;

  std::cin >> size;

  int *array = new int[size];

  delete [] array;

  return 0;
}

Don't forget to delete every array you allocate with new.

Implementations

Although the reference implementation of reStructuredText is written in Python, there are reStructuredText parsers in other languages too.

Python - Docutils

The main distribution of reStructuredText is the Python Docutils package. It contains several conversion tools:

• rst2html - from reStructuredText to HTML
• rst2xml - from reStructuredText to XML
• rst2latex - from reStructuredText to LaTeX
• rst2odt - from reStructuredText to ODF Text (word processor) document.
• rst2s5 - from reStructuredText to S5, a Simple Standards-based Slide Show System
• rst2man - from reStructuredText to Man page

Haskell - Pandoc

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read Markdown and (subsets of) reStructuredText, HTML, and LaTeX, and it can write Markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, and S5 HTML slide shows.

There is an Pandoc online tool (POT) to try this library. Unfortunately, compared to the reStructuredText online renderer (ROR),

• POT truncates input rather more shortly. The POT user must render input in chunks that could be rendered whole by the ROR.
• POT output lacks the helpful error messages displayed by the ROR (and generated by docutils)

Java - JRst

JRst is a Java reStructuredText parser. It can currently output HTML, XHTML, DocBook xdoc and PDF, BUT seems to have serious problems: neither PDF or (X)HTML generation works using the current full download, result pages in (X)HTML are empty and PDF generation fails on IO problems with XSL files (not bundled??). Note that the original JRst has been removed from the website; a fork is found on GitHub.

Scala - Laika

Laika is a new library for transforming markup languages to other output formats. Currently it supports input from Markdown and reStructuredText and produce HTML output. The library is written in Scala but should be also usable from Java.

Perl

• Text::Restructured - Perl implementation of reStructuredText parser
• Dotiac::DTL::Addon::markup - Filters to work with common markup languages - support reStructuredText
• Pod::POM::View::Restructured - View for Pod::POM that outputs reStructuredText

PHP

• Gregwar/RST - A mature PHP5.3 parser with tests
• php-restructuredtext - A simple, incomplete (but functional) implementation

C#/.NET

• reStructuredText for ANTLR - A C# based parser with tests (in progress). It also provides the language server behind reStructuredText extension for Visual Studio Code.

Nim/C

The Nim compiler features the commands rst2htmland rst2tex which transform reStructuredText files to HTML and TeX files. The standard library provides the following modules (used by the compiler) to handle reStructuredText files programmatically:

• rst - implements a reStructuredText parser
• rstast - implements an AST for the reStructuredText parser
• rstgen - implements a generator of HTML/Latex from reStructuredText

Other 3rd party converters

Most (but not all) of these tools are based on Docutils (see above) and provide conversion to or from formats that might not be supported by the main distribution.

From reStructuredText

• restview - This pip-installable python package requires docutils, which does the actual rendering. restview's major ease-of-use feature is that, when you save changes to your document(s), it automagically re-renders and re-displays them. restview
  1. starts a small web server
  2. calls docutils to render your document(s) to HTML
  3. calls your device's browser to display the output HTML.
• rst2pdf - from reStructuredText to PDF
• rst2odp - from reStructuredText to ODF Presentation
• rst2beamer - from reStructuredText to LaTeX beamer Presentation class
• Wikir - from reStructuredText to a Google (and possibly other) Wiki formats
• rst2qhc - Convert a collection of reStructuredText files into a Qt (toolkit) Help file and (optional) a Qt Help Project file

To reStructuredText

• xml2rst is an XSLT script to convert Docutils internal XML representation (back) to reStructuredText
• Pandoc (see above) can also convert from Markdown, HTML and LaTeX to reStructuredText
• db2rst is a simple and limited DocBook to reStructuredText translator
• pod2rst - convert .pod files to reStructuredText files

Extensions

Some projects use reStructuredText as a baseline to build on, or provide extra functionality extending the utility of the reStructuredText tools.

Sphinx

The Sphinx documentation generator translates a set of reStructuredText source files into various output formats, automatically producing cross-references, indices etc.

rest2web

rest2web is a simple tool that lets you build your website from a single template (or as many as you want), and keep the contents in reStructuredText.

Pygments

Pygments is a generic syntax highlighter for general use in all kinds of software such as forum systems, Wikis or other applications that need to prettify source code. See Using Pygments in reStructuredText documents.

Free Editors

While any plain text editor is suitable to write reStructuredText documents, some editors have better support than others.

Emacs

The Emacs support via rst-mode comes as part of the Docutils package under /docutils/tools/editors/emacs/rst.el

Vim

The vim-common package for that comes with most GNU/Linux distributions has reStructuredText syntax highlight and indentation support of reStructuredText out of the box:

• reStructuredText syntax highlighting mode for vim
• VST (Vim reStructured Text) is a plugin for Vim7 with folding for reStructuredText
• Riv.vim - fresh vim plugin for authoring rst and Sphinx doc
• Previm: Vim plugin for live previewing of reStructuredText and other mark up documents

Jed

There is a rst mode for the Jed programmers editor.

gedit

Geany

Geany, a small and lightweight Integrated Development Environment include support for reStructuredText from version 0.12 (October 10, 2007).

Leo

Leo, an outlining editor for programmers, supports reStructuredText via rst-plugin or via "@auto-rst" nodes (it's not well-documented, but @auto-rst nodes allow editing rst files directly, parsing the structure into the Leo outline).

It also provides a way to preview the resulting HTML, in a "viewrendered" pane.

FTE

The FTE Folding Text Editor - a free (licensed under the GNU GPL) text editor for developers. FTE has a mode for reStructuredText support. It provides color highlighting of basic RSTX elements and special menu that provide easy way to insert most popular RSTX elements to a document.

PyK

PyK is a successor of PyEdit and reStInPeace, written in Python with the help of the Qt4 toolkit.

Eclipse

The Eclipse IDE with the ReST Editor plug-in provides support for editing reStructuredText files.

NoTex

NoTex is a browser based (general purpose) text editor, with integrated project management and syntax highlighting. Plus it enables to write books, reports, articles etc. using rST and convert them to LaTex, PDF or HTML. The PDF files are of high publication quality and are produced via Sphinx with the Texlive LaTex suite.

Notepad++

Notepad++ is a general purpose text editor for Windows. It has syntax highlighting for many languages built-in and support for reStructuredText via a user defined language for reStructuredText.

Visual Studio Code

Visual Studio Code is a general purpose text editor for Windows/macOS/Linux. It has syntax highlighting for many languages built-in and supports reStructuredText via an extension from LeXtudio.

Dedicated reStructuredText Editors

• ReSTedit by Dinu Gherman and Bill Bumgarner
• Rest in Peace
• Enthought Tool Suite editor
• ReText a cross platform program that works like Marked.
• RSTPad a standalone cross-platform editor with live preview

Proprietary editors

Sublime Text

Sublime Text is a completely customizable and extensible source code editor available for Windows, OS X, and Linux. Registration is required for long-term use, but all functions are available in the unregistered version, with occasional reminders to purchase a license. Versions 2 and 3 (currently in beta) support reStructuredText syntax highlighting by default, and several plugins are available through the package manager Package Control to provide snippets and code completion, additional syntax highlighting, conversion to/from RST and other formats, and HTML preview in the browser.

BBEdit / TextWrangler

BBEdit (and its free variant TextWrangler) for Mac can syntax-highlight reStructuredText using this codeless language module.

TextMate

TextMate, a proprietary general-purpose GUI text editor for Mac OS X, has a bundle for reStructuredText.

Intype

Intype is a proprietary text editor for Windows, that support reStructuredText out of the box.

E Text Editor

E is a proprietary Text Editor licensed under the "Open Company License". It supports TextMate's bundles, so it should support reStructuredText the same way TextMate does.

PyCharm

PyCharm (and other IntelliJ platform IDEs?) has ReST/Sphinx support (syntax highlighting, autocomplete and preview).)

Wiki

here are some Wiki programs that support the reStructuredText markup as the native markup syntax, or as an add-on:

MediaWiki

MediaWiki reStructuredText extension allows for reStructuredText markup in MediaWiki surrounded by <rst> and </rst>.

rstiki

rstiki is a minimalist single-file personal wiki using reStructuredText syntax (via docutils) inspired by pwyky. It does not support authorship indication, versioning, hierarchy, chrome/framing/templating or styling. It leverages docutils/reStructuredText as the wiki syntax. As such, it's under 200 lines of code, and in a single file. You put it in a directory and it runs.

ikiwiki

Ikiwiki is a wiki compiler. It converts wiki pages into HTML pages suitable for publishing on a website. Ikiwiki stores pages and history in a revision control system such as Subversion or Git.

I did the following to resolve mine:

1. Open VirtualBox and check the new machine that is created for you by GenyMotion
2. Right Click on it and choose Settings then go to the Network section/tab

3. In Adapter 1 tab, It should be attached to Host-Only Adapter. Check what is the name of the used adapter Name then close it.

4. Open File|Preferences in Virtualbox, then go to Network section/tab

5. Under Host-only Networks tab, find the same name you have already gotten in step 3.

6. Double click on that name and apple the following configuration

   • Adapter Tab:
   • IPv4 Adapter: 192.168.65.1

   • IPV4 Network Mask: 255.255.255.0

   • DHCP Server:

   • Check "Enable Server"
   • Server Address: 192.168.65.100
   • Server Mask: 255.255.255.0
   • Lower Address Bound: 192.168.65.101
   • Higher Address Bound: 192.168.65.255

If you want to return the single model object as a json response to a client, you can do this simple solution:

from django.forms.models import model_to_dict
from django.http import JsonResponse

movie = Movie.objects.get(pk=1)
return JsonResponse(model_to_dict(movie))

What you are talking about is the preview image and text that Facebook extracts when you share a link. Facebook uses the Open Graph Protocol to get this data.

Essentially, all you'll have to do is place these og:meta tags on the URL that you want to share -

<meta property="og:title" content="The Rock"/>
<meta property="og:type" content="movie"/>
<meta property="og:url" content="http://www.imdb.com/title/tt0117500/"/>
<meta property="og:image" content="http://ia.media-imdb.com/rock.jpg"/>
<meta property="og:site_name" content="IMDb"/>
<meta property="fb:admins" content="USER_ID"/>
<meta property="og:description"
      content="A group of U.S. Marines, under command of
               a renegade general, take over Alcatraz and
               threaten San Francisco Bay with biological
               weapons."/>

As you can see there are both an image property and a description. When you make changes to your pages og:meta tags, you can test these changes using the Facebook Debugger. It will tell you if you have made any mistakes (and how to fix them!)

When you allocate memory for struct Vector you just allocate memory for pointer x, i.e. for space, where its value, which contains address, will be placed. So such way you do not allocate memory for the block, on which y.x will reference.
