Because the main thread exits.

Put a sleep in the main thread.

cout << "Hello";
sleep(1);

return 0;

The POSIX standard does not specify what happens when the main thread exits.
But in most implementations this will cause all spawned threads to die.

So in the main thread you should wait for the thread to die before you exit. In this case the simplest solution is just to sleep and give the other thread a chance to execute. In real code you would use pthread_join();

#include <iostream>
#include <pthread.h>
using namespace std;

#if defined(__cplusplus)
extern "C"
#endif
void *print_message(void*)
{
    cout << "Threading\n";
}



int main() 
{
    pthread_t t1;

    pthread_create(&t1, NULL, &print_message, NULL);
    cout << "Hello";

    void* result;
    pthread_join(t1,&result);

    return 0;
}

I have Archlinux with php 7.2, which has Curl integrated, so no amount of configuration voodoo would make Composer see ext-curl, that PHP could see and work with happily. Work around is to use Composer with --ignore-platform-reqs.

eg composer update --ignore-platform-reqs

Reference = https://github.com/composer/composer/issues/1426

Try going to "Manage Jenkins"->"Manage Users" go to the specific user, edit his/her configuration "My Views section" default view.

Found a really helpful link for that. Using SQLCMD for this is really easier than solving this with a stored procedure

SELECT  *
FROM    trees
WHERE   trees.`title` COLLATE UTF8_GENERAL_CI LIKE '%elm%'

Actually, if you add COLLATE UTF8_GENERAL_CI to your column's definition, you can just omit all these tricks: it will work automatically.

ALTER TABLE trees 
 MODIFY COLUMN title VARCHAR(…) CHARACTER 
 SET UTF8 COLLATE UTF8_GENERAL_CI. 

This will also rebuild any indexes on this column so that they could be used for the queries without leading '%'

you need implements Parcelable in your ContactBean class, I put one example for you:

public class ContactClass implements Parcelable {

private String id;
private String photo;
private String firstname;
private String lastname;

public ContactClass()
{

}

private ContactClass(Parcel in) {
    firstname = in.readString();
    lastname = in.readString();
    photo = in.readString();
    id = in.readString();

}

@Override
public int describeContents() {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {

    dest.writeString(firstname);
    dest.writeString(lastname);
    dest.writeString(photo);
    dest.writeString(id);

}

 public static final Parcelable.Creator<ContactClass> CREATOR = new Parcelable.Creator<ContactClass>() {
        public ContactClass createFromParcel(Parcel in) {
            return new ContactClass(in);
        }

        public ContactClass[] newArray(int size) {
            return new ContactClass[size];

        }
    };

   // all get , set method 
 }

and this get and set for your code:

Intent intent = new Intent(this,DisplayContact.class);
intent.putExtra("Contact_list", ContactLis);
startActivity(intent);

second class:

ArrayList<ContactClass> myList = getIntent().getParcelableExtra("Contact_list");

I made an extension to disable it on all sites. In doing so I used three techniques: pure CSS, pure JS and hybrid.

The CSS version is similar to the above solutions. The JS one goes a bit like this:

var scroll = function(e) {
    // compute state
    if (stopScrollX || stopScrollY) {
        e.preventDefault();              // this one is the key
        e.stopPropagation();
        window.scroll(scrollToX, scrollToY);
    }
}

document.addEventListener('mousewheel', scroll, false);

The CSS one works when one is using position: fixed elements and let the browser do the scrolling. The JS one is needed when some other JS depends on window (e.g events), which would get blocked by the previous CSS (since it makes the body scroll instead of the window), and works by stopping event propagation at the edges, but needs to synthesize the scrolling of the non-edge component; the downside is that it prevents some types of scrolling to happen (those do work with the CSS one). The hybrid one tries to take a mixed approach by selectively disabling directional overflow (CSS) when scrolling reaches an edge (JS), and in theory could work in both cases, but doesn't quite currently as it has some leeway at the limit.

So depending on the implementations of one's website, one needs to either take one approach or the other.

AndroidStudio is alpha version for now. So you have to edit gradle build script files by yourself. Add next lines to your build.gradle

android {

    signingConfigs {

        release {

            storeFile file('android.keystore')
            storePassword "pwd"
            keyAlias "alias"
            keyPassword "pwd"
        }
    }

    buildTypes {

       release {

           signingConfig signingConfigs.release
       }
    }
}

To actually run your application at emulator or device run gradle installDebug or gradle installRelease.

You can create helloworld project from AndroidStudio wizard to see what structure of gradle files is needed. Or export gradle files from working eclipse project. Also this series of articles are helpfull http://blog.stylingandroid.com/archives/1872#more-1872

After a lot of digging around I finally ended up downloading the source code of the recovery section of Android. Turns out you can actually send commands to the recovery.

 * The arguments which may be supplied in the recovery.command file:
 *   --send_intent=anystring - write the text out to recovery.intent
 *   --update_package=path - verify install an OTA package file
 *   --wipe_data - erase user data (and cache), then reboot
 *   --wipe_cache - wipe cache (but not user data), then reboot
 *   --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

Those are the commands you can use according to the one I found but that might be different for modded files. So using adb you can do this:

adb shell
recovery --wipe_data

Using --wipe_data seemed to do what I was looking for which was handy although I have not fully tested this as of yet.

EDIT:

For anyone still using this topic, these commands may change based on which recovery you are using. If you are using Clockword recovery, these commands should still work. You can find other commands in /cache/recovery/command

For more information please see here: https://github.com/CyanogenMod/android_bootable_recovery/blob/cm-10.2/recovery.c

The exception you get is telling you filedialog is not in your namespace. filedialog (and btw messagebox) is a tkinter module, so it is not imported just with from tkinter import *

>>> from tkinter import *
>>> filedialog
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
NameError: name 'filedialog' is not defined
>>> 

you should use for example:

>>> from tkinter import filedialog
>>> filedialog
<module 'tkinter.filedialog' from 'C:\Python32\lib\tkinter\filedialog.py'>
>>>

or

>>> import tkinter.filedialog as fdialog

or

>>> from tkinter.filedialog import askopenfilename

So this would do for your browse button:

from tkinter import *
from tkinter.filedialog import askopenfilename
from tkinter.messagebox import showerror

class MyFrame(Frame):
    def __init__(self):
        Frame.__init__(self)

        self.master.columnconfigure(5, weight=1)
        self.grid(sticky=W+E+N+S)

        self.button = Button(self, text="Browse", command=self.load_file, width=10)
        self.button.grid(row=1, column=0, sticky=W)

    def load_file(self):
        fname = askopenfilename(filetypes=(("Template files", "*.tplate"),
                                           ("HTML files", "*.html;*.htm"),
                                           ("All files", "*.*") ))
        if fname:
            try:
                print("""here it comes: self.settings["template"].set(fname)""")
            except:                     # <- naked except is a bad idea
                showerror("Open Source File", "Failed to read file\n'%s'" % fname)
            return

jQuery's documentation states:

[jQuery.val] checks, or selects, all the radio buttons, checkboxes, and select options that match the set of values.

This behavior is in jQuery versions 1.2 and above.

You most likely want this:

$("._statusDDL").val('2');

Using standard library:

Assuming that your implementation meaningfully supports SEEK_END:

fseek(f, 0, SEEK_END); // seek to end of file
size = ftell(f); // get current file pointer
fseek(f, 0, SEEK_SET); // seek back to beginning of file
// proceed with allocating memory and reading the file

Linux/POSIX:

You can use stat (if you know the filename), or fstat (if you have the file descriptor).

Here is an example for stat:

#include <sys/stat.h>
struct stat st;
stat(filename, &st);
size = st.st_size;

Win32:

You can use GetFileSize or GetFileSizeEx.

The following revision seeks to more clearly delineate PHP's array_filer(), array_map(), and array_walk(), all of which originate from functional programming:

array_filter() filters out data, producing as a result a new array holding only the desired items of the former array, as follows:

<?php
$array = array(1, "apples",2, "oranges",3, "plums");

$filtered = array_filter( $array, "ctype_alpha");
var_dump($filtered);
?>

live code here

All numeric values are filtered out of $array, leaving $filtered with only types of fruit.

array_map() also creates a new array but unlike array_filter() the resulting array contains every element of the input $filtered but with altered values, owing to applying a callback to each element, as follows:

<?php

$nu = array_map( "strtoupper", $filtered);
var_dump($nu);
?>

live code here

The code in this case applies a callback using the built-in strtoupper() but a user-defined function is another viable option, too. The callback applies to every item of $filtered and thereby engenders $nu whose elements contain uppercase values.

In the next snippet, array walk() traverses $nu and makes changes to each element vis a vis the reference operator '&'. The changes occur without creating an additional array. Every element's value changes in place into a more informative string specifying its key, category and value.

<?php

$f = function(&$item,$key,$prefix) {
    $item = "$key: $prefix: $item";
}; 
array_walk($nu, $f,"fruit");
var_dump($nu);    
?>    

See demo

Note: the callback function with respect to array_walk() takes two parameters which will automatically acquire an element's value and its key and in that order, too when invoked by array_walk(). (See more here).

Firefox doesn't support outerHTML, so you need to define a function to help support it:

function outerHTML(node) {
    return node.outerHTML || (
        function(n) {
            var div = document.createElement('div');
            div.appendChild( n.cloneNode(true) );
            var h = div.innerHTML;
            div = null;
            return h;
        }
    )(node);
}

Then, you can use outerHTML:

var x = outerHTML($('#container').get(0));
$('#save').val(x);

TypeScript is one of the best solution for now

TypeScript extends JavaScript by adding types to the language.

You can get the user name using System.Security.Principal.WindowsIdentity.GetCurrent() but there is not way to get current user password!

Using wheel compiled packages.

bundle up:

$ tempdir=$(mktemp -d /tmp/wheelhouse-XXXXX)
$ pip wheel -r requirements.txt --wheel-dir=$tempdir
$ cwd=`pwd`
$ (cd "$tempdir"; tar -cjvf "$cwd/bundled.tar.bz2" *)

copy tarball and install:

$ tempdir=$(mktemp -d /tmp/wheelhouse-XXXXX)
$ (cd $tempdir; tar -xvf /path/to/bundled.tar.bz2)
$ pip install --force-reinstall --ignore-installed --upgrade --no-index --no-deps $tempdir/*

Note wheel binary packages are not across machines.

First we need to find a Button:

Button mButton = (Button) findViewById(R.id.my_button);

After that, you must implement View.OnClickListener and there you should find the TextView and execute the method setText:

mButton.setOnClickListener(new View.OnClickListener {
    public void onClick(View v) {
        final TextView mTextView = (TextView) findViewById(R.id.my_text_view);
        mTextView.setText("Some Text");
    }
});

I usually manually set the port that I am listening on in the app.js file (assuming you are using express.js

var server = app.listen(8080, function() {
    console.log('Ready on port %d', server.address().port);
});

This will log Ready on port 8080 to your console.

Delete it with git tag -d <tagname> and then recreate it on the correct commit.

I second Randell's answer.

However, one could always integrate a GeoIP such as http://www.maxmind.com/app/php or http://www.ipinfodb.com/. Then you can save the results with the codeigniter session class.

If you want to use the ipinfodb.com api You can add the ip2locationlite.class.php file to your codeigniter application library folder and then create a model function to do whatever geoip logic you need for your application, such as:

function geolocate()
{
    $ipinfodb = new ipinfodb;
    $ipinfodb->setKey('API KEY');

    //Get errors and locations
    $locations = $ipinfodb->getGeoLocation($this->input->ip_address());
    $errors = $ipinfodb->getError();

   //Set geolocation cookie
   if(empty($errors))
   {
       foreach ($locations as $field => $val):
            if($field === 'CountryCode')
            {
                $place = $val;
            }
       endforeach;
   }
   return $place;
}

You can use full_picture instead of picture key to get full size image.

I know it's a relative old post but, I would like to share what worked for me: I've simply input "http://" before "localhost" in the url. Hope it helps somebody.

Best way to achieve same is stated below:

function getKey(key) {
  return `${key}`;
}

var obj = {key1: "value1", key2: "value2", [getKey('key3')]: "value3"};

//console.log(obj);

Mostly, those restrictions are in place because of language designers. The underlying justification may be compatibility with languange history, ideals, or simplification of compiler design.

The compiler may (and does) choose to:

• create a big if-else statement
• use a MSIL switch instruction (jump table)
• build a Generic.Dictionary<string,int32>, populate it on first use, and call Generic.Dictionary<>::TryGetValue() for a index to pass to a MSIL switch instruction (jump table)
• use a combination of if-elses & MSIL "switch" jumps

The switch statement IS NOT a constant time branch. The compiler may find short-cuts (using hash buckets, etc), but more complicated cases will generate more complicated MSIL code with some cases branching out earlier than others.

To handle the String case, the compiler will end up (at some point) using a.Equals(b) (and possibly a.GetHashCode() ). I think it would be trival for the compiler to use any object that satisfies these constraints.

As for the need for static case expressions... some of those optimisations (hashing, caching, etc) would not be available if the case expressions weren't deterministic. But we've already seen that sometimes the compiler just picks the simplistic if-else-if-else road anyway...

Edit: lomaxx - Your understanding of the "typeof" operator is not correct. The "typeof" operator is used to obtain the System.Type object for a type (nothing to do with its supertypes or interfaces). Checking run-time compatibility of an object with a given type is the "is" operator's job. The use of "typeof" here to express an object is irrelevant.

Had the very same problem, but in my case the reason was update of Ubuntu and php version - from 18.04 and php-7.2 up to 20.04 and php-7.4.

The Nginx server was the same, so in my /etc/nginx/sites-available/default was old data:

server {
  location /pma {
    location ~ ^/pma/(.+\.php)$ {
      fastcgi_pass unix:/run/php/php7.2-fpm.sock;
    }
  }
}

I could not get phpmyadmin to work with any of php.ini changes and all answers from this thread, but at some moment I had opened the /etc/nginx/sites-available/default and realised, that I still had old version of php. So I just changed it to

fastcgi_pass unix:/run/php/php7.4-fpm.sock;

and the issue was gone, phpmyadmin magically started to work without any mysqli-file complaint. I even double checked it, but yeap, that's how it works - if you have wrong version for php-fpm.sock in your nginx config file, your phpmyadmin will not work, but the shown reason will be 'The mysqli extension is missing'

I don't see an obvious problem with the above.

It's possible your ldap.conf is being overridden, but the command-line options will take precedence, ldapsearch will ignore BINDDN in the main ldap.conf, so the only parameter that could be wrong is the URI. (The order is ETCDIR/ldap.conf then ~/ldaprc or ~/.ldaprc and then ldaprc in the current directory, though there environment variables which can influence this too, see man ldapconf.)

Try an explicit URI:

ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base -H ldap://localhost

or prevent defaults with:

LDAPNOINIT=1 ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

If that doesn't work, then some troubleshooting (you'll probably need the full path to the slapd binary for these):

• make sure your slapd.conf is being used and is correct (as root)

  slapd -T test -f slapd.conf -d 65535

  You may have a left-over or default slapd.d configuration directory which takes preference over your slapd.conf (unless you specify your config explicitly with -f, slapd.conf is officially deprecated in OpenLDAP-2.4). If you don't get several pages of output then your binaries were built without debug support.

• stop OpenLDAP, then manually start slapd in a separate terminal/console with debug enabled (as root, ^C to quit)

  slapd -h ldap://localhost -d 481

  then retry the search and see if you can spot the problem (there will be a lot of schema noise in the start of the output unfortunately). (Note: running slapd without the -u/-g options can change file ownerships which can cause problems, you should usually use those options, probably -u ldap -g ldap )

• if debug is enabled, then try also

  ldapsearch -v -d 63 -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

I just wanted to answer something new for this question - J2V8.

Author Ian Bull says "Rhino and Nashorn are two common JavaScript runtimes, but these did not meet our requirements in a number of areas:

Neither support ‘Primitives‘. All interactions with these platforms require wrapper classes such as Integer, Double or Boolean. Nashorn is not supported on Android. Rhino compiler optimizations are not supported on Android. Neither engines support remote debugging on Android.""

I solved my problem a different way. The problem is that wamp's GUI was misleading: it claimed that I had php_openssl enabled.. and if I clicked on php.ini on the same GUI.. it actually showed that extension=php_openssl.dll was uncommented..

I'm not sure if i'm using the same installer version of composer of the OP, but it actually asks you at the beginning to specify the php.exe that you like to apply composer on (which basically ensures that no one tries to apply composer to the wrong php executable as what happened with the OP)..

The way I solved this was by going myself into the installation of php within the wamp package: C:\wamp\bin\php\php5.4.12 and looking php.in there.. when I opened it I was shocked that the line extension=php_openssl.dll was actually commented! I uncommented it and it worked just fine.

According to the error message, you declared myLoc as a pointer to an NSInteger (NSInteger *myLoc) rather than an actual NSInteger (NSInteger myLoc). It needs to be the latter.

Or even a way that either variable can be uninitialised or an empty array or an array of objects (eg Dictionary objects). Only handles one dimension at a time, though. Also, it APPENDS arr2 to arr1 rather than merges.

Function appendArray(ByVal arr1 As Variant, ByVal arr2 As Variant) As Variant
    Dim holdarr As Variant
    Dim ub1 As Long
    Dim ub2 As Long
    Dim i As Long
    Dim newind As Long

                            ' Allows for one or both variants to not be arrays
    If IsEmpty(arr1) Or Not IsArray(arr1) Then
        arr1 = Array()
    End If

    If IsEmpty(arr2) Or Not IsArray(arr2) Then
        arr2 = Array()
    End If
                            ' Now we assume we DO have two ARRAYS, even if one or the other
                            ' has no elements
    ub1 = UBound(arr1)
    ub2 = UBound(arr2)

    If ub1 = -1 Then
        appendArray = arr2
        Exit Function
    End If

    If ub2 = -1 Then
        appendArray = arr1
        Exit Function
    End If

            ' Copy the first array. We know it is not empty.
    holdarr = arr1

            ' Grow it to the final size we need, keeping the current contents
    ReDim Preserve holdarr(ub1 + ub2 + 1)

            ' Set the starting new index
    newind = UBound(arr1) + 1

            ' Append the second array, allowing that it might be an array of objects
    For i = 0 To ub2
        If VarType(arr2(i)) = vbObject Then
            Set holdarr(newind) = arr2(i)
        Else
            holdarr(newind) = arr2(i)
        End If
        newind = newind + 1
    Next i
            ' Return the appended array
    appendArray = holdarr
End Function

The field separator in gawk (at least) can be a string as well as a character (it can also be a regex). If your data is consistent, then this will work:

awk -F "  " '{print $2,$1}' inputfile

That's two spaces between the double quotes.

in 2019 I faced the same problem and I searched the internet and found the following which I am sharing with all.

In android studio letter R stands for the resources and this error occurs because of the build process not able to sync resources with your project. In other words, this error is caused when Android Studio can’t generate your R.java file correctly. This problem happens when you shift code to another system or while building the android project for the first time. So when you create a new activity or new class you will see an error message like “cannot resolve symbol r” with a red underline.

Below you can find the possible ways to fix cannot resolve symbol r in android studio.

Update Project Gradle To Latest Version Always use the latest version of Gradle to work android studio properly.

Sync Project With Gradle File Once you update the Gradle plugin you need to sync project with the Gradle file. Open android studio and click on Files > Sync Project with Gradle Files option.

Clean and Rebuild Project The most effective solution is the simplest: clean and rebuild your project. Select Build > Clean Project from the Android Studio toolbar, wait a few moments, and then build your project by selecting Build > Rebuild Project.

Invalidate Caches / Restart If you encounter this error after moving some files and directories around, then it’s possible that the R.layout error is being caused by a mismatch between Android Studio’s cache and your project’s current layout. If you suspect this may be the case, then select File > Invalidate Caches / Restart > Invalidate and Restart from Android Studio’s toolbar. Issues with the names of your resources can also prevent the R.java file from being created correctly, so check that you don't have multiple resources with the same name and that none of your file names contain invalid characters. Android Studio only supports lowercase a-z, 0-9, full stops and underscores, and a single invalid character can cause an R.layout error across your entire project, even if you don’t actually use this resource anywhere in your project!

My problem and its solution: In my case, I applied all the above but could not solve the problem. Thus I started a new project and pasted my code one by one and validated my code with running the app. Finally, at one point when I first deleted the code in colors.xml and copied and pasted code below in colors.xml file, I got the error.

<color name="bg_login">#26ae90</color>
<color name="bg_register">#2e3237</color>
<color name="bg_main">#428bca</color>

<color name="btn_login_bg">#eceef1</color>
<color name="lbl_name">#333333</color>
<color name="btn_logut_bg">#ff6861</color>

when I undo my changes the error vanished again. Thus my code in colors.xml is not the code above and the code already in colors.xml i.e

<color name="colorPrimary">#008577</color>
<color name="colorPrimaryDark">#00574B</color>
<color name="colorAccent">#D81B60</color>

"Maybe its because i did not have color primary defined" Hope it will help someone like me who is new in programming.

The above answers require you to malloc a new stream object.

public <T>
boolean containsByLambda(Collection<? extends T> c, Predicate<? super T> p) {

    for (final T z : c) {
        if (p.test(z)) {
            return true;
        }
    }
    return false;
}

public boolean containsTabById(TabPane tabPane, String id) {
    return containsByLambda(tabPane.getTabs(), z -> z.getId().equals(id));
}
...
if (containsTabById(tabPane, idToCheck))) {
   ...
}

After introducing a bunch of helper methods, you will be able run parallel queries with this simple syntax:

const int DegreeOfParallelism = 10;
IEnumerable<double> result = await Enumerable.Range(0, 1000000)
    .Split(DegreeOfParallelism)
    .SelectManyAsync(async i => await CalculateAsync(i).ConfigureAwait(false))
    .ConfigureAwait(false);

What happens here is: we split source collection into 10 chunks (.Split(DegreeOfParallelism)), then run 10 tasks each processing its items one by one (.SelectManyAsync(...)) and merge those back into a single list.

Worth mentioning there is a simpler approach:

double[] result2 = await Enumerable.Range(0, 1000000)
    .Select(async i => await CalculateAsync(i).ConfigureAwait(false))
    .WhenAll()
    .ConfigureAwait(false);

But it needs a precaution: if you have a source collection that is too big, it will schedule a Task for every item right away, which may cause significant performance hits.

Extension methods used in examples above look as follows:

public static class CollectionExtensions
{
    /// <summary>
    /// Splits collection into number of collections of nearly equal size.
    /// </summary>
    public static IEnumerable<List<T>> Split<T>(this IEnumerable<T> src, int slicesCount)
    {
        if (slicesCount <= 0) throw new ArgumentOutOfRangeException(nameof(slicesCount));

        List<T> source = src.ToList();
        var sourceIndex = 0;
        for (var targetIndex = 0; targetIndex < slicesCount; targetIndex++)
        {
            var list = new List<T>();
            int itemsLeft = source.Count - targetIndex;
            while (slicesCount * list.Count < itemsLeft)
            {
                list.Add(source[sourceIndex++]);
            }

            yield return list;
        }
    }

    /// <summary>
    /// Takes collection of collections, projects those in parallel and merges results.
    /// </summary>
    public static async Task<IEnumerable<TResult>> SelectManyAsync<T, TResult>(
        this IEnumerable<IEnumerable<T>> source,
        Func<T, Task<TResult>> func)
    {
        List<TResult>[] slices = await source
            .Select(async slice => await slice.SelectListAsync(func).ConfigureAwait(false))
            .WhenAll()
            .ConfigureAwait(false);
        return slices.SelectMany(s => s);
    }

    /// <summary>Runs selector and awaits results.</summary>
    public static async Task<List<TResult>> SelectListAsync<TSource, TResult>(this IEnumerable<TSource> source, Func<TSource, Task<TResult>> selector)
    {
        List<TResult> result = new List<TResult>();
        foreach (TSource source1 in source)
        {
            TResult result1 = await selector(source1).ConfigureAwait(false);
            result.Add(result1);
        }
        return result;
    }

    /// <summary>Wraps tasks with Task.WhenAll.</summary>

    }
}

For those, who want to do it automatically, I have wrote a little two-lines bash script which does next two things:

1. Looks for all *.aar files and extracts classes.jar from them

2. Renames extracted classes.jar to be like the aar but with a new extension

   find . -name '*.aar' -exec sh -c 'unzip -d `dirname {}` {} classes.jar' \;
   find . -name '*.aar' -exec sh -c 'mv `dirname {}`/classes.jar `echo {} | sed s/aar/jar/g`' \;
   

That's it!

TortoiseSVN users: right click on the root project directory > TortoiseSVN > Clean up... (make sure you check all the boxes). This worked for me.

Your class JSON_result does not match your JSON string. Note how the object JSON_result is going to represent is wrapped in another property named "Venue".

So either create a class for that, e.g.:

Public Class Container
    Public Venue As JSON_result
End Class

Public Class JSON_result
    Public ID As Integer
    Public Name As String
    Public NameWithTown As String
    Public NameWithDestination As String
    Public ListingType As String
End Class

Dim obj = JsonConvert.DeserializeObject(Of Container)(...your_json...)

or change your JSON string to

{
    "ID": 3145,
    "Name": "Big Venue, Clapton",
    "NameWithTown": "Big Venue, Clapton, London",
    "NameWithDestination": "Big Venue, Clapton, London",
    "ListingType": "A",
    "Address": {
        "Address1": "Clapton Raod",
        "Address2": "",
        "Town": "Clapton",
        "County": "Greater London",
        "Postcode": "PO1 1ST",
        "Country": "United Kingdom",
        "Region": "Europe"
    },
    "ResponseStatus": {
        "ErrorCode": "200",
        "Message": "OK"
    }
}

or use e.g. a ContractResolver to parse the JSON string.

prefer struct, and it's what std::greater do

struct Compare {
  bool operator()(Node const&, Node &) {}
}

The problem is that you're trying to print an unicode character to a possibly non-unicode terminal. You need to encode it with the 'replace option before printing it, e.g. print ch.encode(sys.stdout.encoding, 'replace').

I just got this error and i came to know that it is about the local variable alias

at the end of the stored procedure i had like

select @localvariable1,@localvariable2

it was working fine in sql but when i ran this in ssrs it was always throwing error but after I gave alias it is fixed

select @localvariable1 as A,@localvariable2 as B

var result = from sc in enumerableOfSomeClass
             join soc in enumerableOfSomeOtherClass
             on sc.Property1 equals soc.Property2
             select new { SomeClass = sc, SomeOtherClass = soc };

Would be equivalent to:

var result = enumerableOfSomeClass
    .Join(enumerableOfSomeOtherClass,
          sc => sc.Property1,
          soc => soc.Property2,
          (sc, soc) => new
                       {
                           SomeClass = sc,
                           SomeOtherClass = soc
                       });

As you can see, when it comes to joins, query syntax is usually much more readable than lambda syntax.

Neither way is necessarily correct or incorrect, they are just two different kinds of class elements:

• Elements outside the __init__ method are static elements; they belong to the class.
• Elements inside the __init__ method are elements of the object (self); they don't belong to the class.

You'll see it more clearly with some code:

class MyClass:
    static_elem = 123

    def __init__(self):
        self.object_elem = 456

c1 = MyClass()
c2 = MyClass()

# Initial values of both elements
>>> print c1.static_elem, c1.object_elem 
123 456
>>> print c2.static_elem, c2.object_elem
123 456

# Nothing new so far ...

# Let's try changing the static element
MyClass.static_elem = 999

>>> print c1.static_elem, c1.object_elem
999 456
>>> print c2.static_elem, c2.object_elem
999 456

# Now, let's try changing the object element
c1.object_elem = 888

>>> print c1.static_elem, c1.object_elem
999 888
>>> print c2.static_elem, c2.object_elem
999 456

As you can see, when we changed the class element, it changed for both objects. But, when we changed the object element, the other object remained unchanged.

I'm guessing

x= data[:,0]
y= data[:,1]

The correct mechanism for C++ in anonymous namespaces. If you want something that is local to your file, you should use an anonymous namespace rather than the static modifier.

Find server.xml at $CATALINA_BASE/conf/server.xml

Find appBase attribute in <Host> element

by default it will be something like : <Host name="localhost" appBase="webapps ...>

Change appBase to your required path. There are different way people put it, but I use

/c:/myfolder/newwebapps

Remember, no slash at the end, but at start. Also note it's direction as well.

Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.

If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like

double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);

(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)

I just edited my iPhone's 'hosts' file successfully (on Jailbroken iOS 4.0).

• Installed OpenSSH onto iPhone via Cydia
• Using a SFTP client like FileZilla on my computer, I connected to my iPhone
  • Address: [use your phone's IP address or hostname, eg. simophone.local]
  • Username: root
  • Password: alpine
• Located the /etc/hosts file
• Made a backup on my computer (in case I want to revert my changes later)
• Edited the hosts file in a decent text editor (such as Notepad++). See here for an explanation of the hosts file.
• Uploaded the changes, overwriting the hosts file on the iPhone

The phone does cache some webpages and DNS queries, so a reboot or clearing the cache may help. Hope that helps someone.

The above Answer solves our problem but in addition to that. if we are trying to decompress a uncompressed("not a zip format") byte[] . we will get "Not in GZIP format" exception message.

For solving that we can add addition code in our Class.

public static boolean isCompressed(final byte[] compressed) {
    return (compressed[0] == (byte) (GZIPInputStream.GZIP_MAGIC)) && (compressed[1] == (byte) (GZIPInputStream.GZIP_MAGIC >> 8));
}

My Complete Compression Class with compress/decompress would look like:

import java.io.BufferedReader;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

public class GZIPCompression {
  public static byte[] compress(final String str) throws IOException {
    if ((str == null) || (str.length() == 0)) {
      return null;
    }
    ByteArrayOutputStream obj = new ByteArrayOutputStream();
    GZIPOutputStream gzip = new GZIPOutputStream(obj);
    gzip.write(str.getBytes("UTF-8"));
    gzip.flush();
    gzip.close();
    return obj.toByteArray();
  }

  public static String decompress(final byte[] compressed) throws IOException {
    final StringBuilder outStr = new StringBuilder();
    if ((compressed == null) || (compressed.length == 0)) {
      return "";
    }
    if (isCompressed(compressed)) {
      final GZIPInputStream gis = new GZIPInputStream(new ByteArrayInputStream(compressed));
      final BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(gis, "UTF-8"));

      String line;
      while ((line = bufferedReader.readLine()) != null) {
        outStr.append(line);
      }
    } else {
      outStr.append(compressed);
    }
    return outStr.toString();
  }

  public static boolean isCompressed(final byte[] compressed) {
    return (compressed[0] == (byte) (GZIPInputStream.GZIP_MAGIC)) && (compressed[1] == (byte) (GZIPInputStream.GZIP_MAGIC >> 8));
  }
}

Ok found out the Tomcat file server.xml must be configured as well for the data source to work. So just add:

<Resource 
auth="Container" 
driverClassName="org.apache.derby.jdbc.EmbeddedDriver" 
maxActive="20" 
maxIdle="10" 
maxWait="-1" 
name="ds/flexeraDS" 
type="javax.sql.DataSource" 
url="jdbc:derby:flexeraDB;create=true" 
  />

?HTML:

<span class="right">Right aligned</span><span class="left">Left aligned</span>?

css:

.right{
    float:right;
}

.left{
    float:left;
}

Using modal.hide would only hide the modal. If you are using overlay underneath the modal, it would still be there. use click call to actually close the modal and remove the overlay.

$("#modalID .close").click()

AJAX does the magic:

$(document).ready(function(

    $.ajax({ url: 'script.php?argument=value&foo=bar' });

));

127.0.0.1 restricts access on every interface on port 8000 except development computer. change it to 0.0.0.0:8000 this will allow connection from curl.

I am running JConsole/JVisualVm on windows hooking to tomcat running Linux Redhat ES3.

Disabling packet filtering using the following command did the trick for me:

/usr/sbin/iptables -I INPUT -s jconsole-host -p tcp --destination-port jmxremote-port -j ACCEPT

where jconsole-host is either the hostname or the host address on which JConsole runs on and jmxremote-port is the port number set for com.sun.management.jmxremote.port for remote management.

Actions act = new Actions(driver);
act.keyDown(Keys.CONTROL).sendKeys("a").keyUp(Keys.CONTROL).build().perform();

There are two ways of doing this.

Most of the answers have correctly pointed out that style.display has no value called "hidden". It should be none.

If you want to use "hidden" the syntax should be as follows.

object.style.visibility="hidden"

The difference between the two is the visibility="hidden" property will only hide the contents of you element but retain it position on the page. Whereas the display ="none" will hide your complete element and the rest of the elements on the page will fill that void created by it.

Check this illustration

I have set the ANDROID_HOME = [PATH_OF_MY_ANDROID_SDK] to my environment variable. That solution works for me.

\ does the job. @Guillaume's answer and @George's comment clearly answer this question. Here I explains why The backslash has to be the very last character before the end of line character. Consider this command:

   mysql -uroot \
   -hlocalhost      

If there is a space after \, the line continuation will not work. The reason is that \ removes the special meaning for the next character which is a space not the invisible line feed character. The line feed character is after the space not \ in this example.

@Primary annotation when used against a method like below works good if the two data sources are on the same db location/server.

@Bean(name = "datasource1")
@ConfigurationProperties("database1.datasource")
@Primary
public DataSource dataSource(){
  return DataSourceBuilder.create().build();
}

@Bean(name = "datasource2")
@ConfigurationProperties("database2.datasource")
public DataSource dataSource2(){
  return DataSourceBuilder.create().build();
}

If the data sources are on different servers its better to use @Component along with @Primary annotation. The following code snippet works well on two different data sources at different locations

database1.datasource.url = jdbc:mysql://127.0.0.1:3306/db1
database1.datasource.username = root
database1.datasource.password = mysql
database1.datasource.driver-class-name=com.mysql.jdbc.Driver

database2.datasource1.url = jdbc:mysql://192.168.113.51:3306/db2
database2.datasource1.username = root
database2.datasource1.password = mysql
database2.datasource1.driver-class-name=com.mysql.jdbc.Driver

@Configuration
@Primary
@Component
@ComponentScan("com.db1.bean")
class DBConfiguration1{
    @Bean("db1Ds")
    @ConfigurationProperties(prefix="database1.datasource")
    public DataSource primaryDataSource() {
        return DataSourceBuilder.create().build();
    }

}

@Configuration
@Component
@ComponentScan("com.db2.bean")
class DBConfiguration2{
    @Bean("db2Ds")
    @ConfigurationProperties(prefix="database2.datasource1")
    public DataSource primaryDataSource() {
        return DataSourceBuilder.create().build();
    }

}

Render Line Endings is a VS Code extension that is still actively maintained (as of Apr 2020):

https://marketplace.visualstudio.com/items?itemName=medo64.render-crlf

It can be configured like this:

{
    "editor.renderWhitespace": "all",
    "code-eol.newlineCharacter": "¬",
    "code-eol.returnCharacter" : "¤",
    "code-eol.crlfCharacter"   : "¤¬",

and looks like this:

all you need is to tie the group to a different item in your model

@Html.RadioButtonFor(x => x.Field1, "Milk")
@Html.RadioButtonFor(x => x.Field1, "Butter")

@Html.RadioButtonFor(x => x.Field2, "Water")
@Html.RadioButtonFor(x => x.Field2, "Beer")

You need to use HAVING, not WHERE.

The difference is: the WHERE clause filters which rows MySQL selects. Then MySQL groups the rows together and aggregates the numbers for your COUNT function.

HAVING is like WHERE, only it happens after the COUNT value has been computed, so it'll work as you expect. Rewrite your subquery as:

(                  -- where that pid is in the set:
SELECT c2.pid                  -- of pids
FROM Catalog AS c2             -- from catalog
WHERE c2.pid = c1.pid
HAVING COUNT(c2.sid) >= 2)

You can use the date function to find how many days in a month there are.

// Get the timestamp for the date/month in question.
$ts = strtotime('April 2010');

echo date('t', $ts); 
// Result: 30, therefore, April 30, 2010 is the last day of that month.

Hope that helps.

EDIT: After reading Luis' answer, it occurred to me you may want it in the right format (YY-mm-dd). It may be obvious, but doesn't hurt to mention:

// After the above code
echo date('Y-m-t', $ts);

I thought Activity was deprecated

No.

So for API Level 22 (with a minimum support for API Level 15 or 16), what exactly should I use both to host the components, and for the components themselves? Are there uses for all of these, or should I be using one or two almost exclusively?

Activity is the baseline. Every activity inherits from Activity, directly or indirectly.

FragmentActivity is for use with the backport of fragments found in the support-v4 and support-v13 libraries. The native implementation of fragments was added in API Level 11, which is lower than your proposed minSdkVersion values. The only reason why you would need to consider FragmentActivity specifically is if you want to use nested fragments (a fragment holding another fragment), as that was not supported in native fragments until API Level 17.

AppCompatActivity is from the appcompat-v7 library. Principally, this offers a backport of the action bar. Since the native action bar was added in API Level 11, you do not need AppCompatActivity for that. However, current versions of appcompat-v7 also add a limited backport of the Material Design aesthetic, in terms of the action bar and various widgets. There are pros and cons of using appcompat-v7, well beyond the scope of this specific Stack Overflow answer.

ActionBarActivity is the old name of the base activity from appcompat-v7. For various reasons, they wanted to change the name. Unless some third-party library you are using insists upon an ActionBarActivity, you should prefer AppCompatActivity over ActionBarActivity.

So, given your minSdkVersion in the 15-16 range:

• If you want the backported Material Design look, use AppCompatActivity

• If not, but you want nested fragments, use FragmentActivity

• If not, use Activity

Just adding from comment as note: AppCompatActivity extends FragmentActivity, so anyone who needs to use features of FragmentActivity can use AppCompatActivity.

[[ ]] double brackets are unsuported under certain version of SunOS and totally unsuported inside function declarations by : GNU bash, version 2.02.0(1)-release (sparc-sun-solaris2.6)

Unless PHP has a builtin for that, you won't be able to do it in less than O(n) - enumerating over all the keys and checking for integer type. In fact, you also want to make sure there are no holes, so your algorithm might look like:

for i in 0 to len(your_array):
    if not defined(your-array[i]):
        # this is not an array array, it's an associative array :)

But why bother? Just assume the array is of the type you expect. If it isn't, it will just blow up in your face - that's dynamic programming for you! Test your code and all will be well...

You can initialize after filling the array or you can write:

 small =~ unsigned(0)/2; // Using the bit-wise complement to flip 0's bits and dividing by 2 because unsigned can hold twice the +ve value an

integer can hold.

 big =- 1*(small) - 1;

instead of:

big = small = values[0]

because when you write this line before filling the array, big and small values will equal to a random leftover value (as integer is a POD) from the memory and if those numbers are either bigger or smaller than any other value in you array, you will get them as an output.

If you want to check whether a List or Set contains a set of specific values (instead of comparing it with an already existing collection), often the toString method of collections is handy:

String[] actualResult = calltestedmethod();
assertEquals("[foo, bar]", Arrays.asList(actualResult).toString());

List otherResult = callothertestedmethod();
assertEquals("[42, mice]", otherResult.toString());

This is a bit shorter than first constructing the expected collection and comparing it with the actual collection, and easier to write and correct.

(Admittedly, this is not a particularily clean method, and can't distinguish an element "foo, bar" from two elements "foo" and "bar". But in practice I think it's most important that it's easy and fast to write tests, otherwise many developers just won't without being pressed.)

Unit test is usually done for a single functionality implemented in Software module. The scope of testing is entirely within this SW module. Unit test never fulfils the final functional requirements. It comes under whitebox testing methodology..

Whereas Integration test is done to ensure the different SW module implementations. Testing is usually carried out after module level integration is done in SW development.. This test will cover the functional requirements but not enough to ensure system validation.

Here is some code that show how it works.

class Test
{
    public static void main(String args[]) 
    { 
        System.out.println(Test.test()); 
    }

    public static String test()
    {
        try {
            System.out.println("try");
            throw new Exception();
        } catch(Exception e) {
            System.out.println("catch");
            return "return"; 
        } finally {  
            System.out.println("finally");
            return "return in finally"; 
        }
    }
}

The results is:

try
catch
finally
return in finally

No need to update gradle for making release application in Android studio.If you were eclipse user then it will be so easy for you. If you are new then follow the steps

1: Go to the "Build" at the toolbar section. 2: Choose "Generate Signed APK..." option.

3:fill opened form and go next 4 :if you already have .keystore or .jks then choose that file enter your password and alias name and respective password. 5: Or don't have .keystore or .jks file then click on Create new... button as shown on pic 1 then fill the form.

Above process was to make build manually. If You want android studio to automatically Signing Your App

In Android Studio, you can configure your project to sign your release APK automatically during the build process:

On the project browser, right click on your app and select Open Module Settings. On the Project Structure window, select your app's module under Modules. Click on the Signing tab. Select your keystore file, enter a name for this signing configuration (as you may create more than one), and enter the required information. Figure 4. Create a signing configuration in Android Studio.

Click on the Build Types tab. Select the release build. Under Signing Config, select the signing configuration you just created. Figure 5. Select a signing configuration in Android Studio.

SQL tables have no implicit ordering, the order has to come from the data. Perhaps you should add a field to your table (e.g. an int counter) and re-import the data.

However that will only give the order of the import and not the data. If your data has no ordering you have to find out how to add it.

EDIT: you say

...to make sure it imported everything.

What's wrong with using row count?

FWIW, here are a couple of non-RE alternatives that I think are neater than poke's solution.

The first uses str.index and checks for ValueError:

def findall(sub, string):
    """
    >>> text = "Allowed Hello Hollow"
    >>> tuple(findall('ll', text))
    (1, 10, 16)
    """
    index = 0 - len(sub)
    try:
        while True:
            index = string.index(sub, index + len(sub))
            yield index
    except ValueError:
        pass

The second tests uses str.find and checks for the sentinel of -1 by using iter:

def findall_iter(sub, string):
    """
    >>> text = "Allowed Hello Hollow"
    >>> tuple(findall_iter('ll', text))
    (1, 10, 16)
    """
    def next_index(length):
        index = 0 - length
        while True:
            index = string.find(sub, index + length)
            yield index
    return iter(next_index(len(sub)).next, -1)

To apply any of these functions to a list, tuple or other iterable of strings, you can use a higher-level function —one that takes a function as one of its arguments— like this one:

def findall_each(findall, sub, strings):
    """
    >>> texts = ("fail", "dolly the llama", "Hello", "Hollow", "not ok")
    >>> list(findall_each(findall, 'll', texts))
    [(), (2, 10), (2,), (2,), ()]
    >>> texts = ("parallellized", "illegally", "dillydallying", "hillbillies")
    >>> list(findall_each(findall_iter, 'll', texts))
    [(4, 7), (1, 6), (2, 7), (2, 6)]
    """
    return (tuple(findall(sub, string)) for string in strings)

I have added a helper da() to Laravel which in fact works as an alias for dd($object->toArray())

Here is the Gist: https://gist.github.com/TommyZG/0505eb331f240a6324b0527bc588769c

A modification of the code by @CarloCannas:

public static void sudo(String...strings) {
    try{
        Process su = Runtime.getRuntime().exec("su");
        DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());

        for (String s : strings) {
            outputStream.writeBytes(s+"\n");
            outputStream.flush();
        }

        outputStream.writeBytes("exit\n");
        outputStream.flush();
        try {
            su.waitFor();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        outputStream.close();
    }catch(IOException e){
        e.printStackTrace();
    }
}

(You are welcome to find a better place for outputStream.close())

Usage example:

private static void suMkdirs(String path) {
    if (!new File(path).isDirectory()) {
        sudo("mkdir -p "+path);
    }
}

Update: To get the result (the output to stdout), use:

public static String sudoForResult(String...strings) {
    String res = "";
    DataOutputStream outputStream = null;
    InputStream response = null;
    try{
        Process su = Runtime.getRuntime().exec("su");
        outputStream = new DataOutputStream(su.getOutputStream());
        response = su.getInputStream();

        for (String s : strings) {
            outputStream.writeBytes(s+"\n");
            outputStream.flush();
        }

        outputStream.writeBytes("exit\n");
        outputStream.flush();
        try {
            su.waitFor();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        res = readFully(response);
    } catch (IOException e){
        e.printStackTrace();
    } finally {
        Closer.closeSilently(outputStream, response);
    }
    return res;
}
public static String readFully(InputStream is) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    byte[] buffer = new byte[1024];
    int length = 0;
    while ((length = is.read(buffer)) != -1) {
        baos.write(buffer, 0, length);
    }
    return baos.toString("UTF-8");
}

The utility to silently close a number of Closeables (So?ket may be no Closeable) is:

public class Closer {
// closeAll()
public static void closeSilently(Object... xs) {
    // Note: on Android API levels prior to 19 Socket does not implement Closeable
    for (Object x : xs) {
        if (x != null) {
            try {
                Log.d("closing: "+x);
                if (x instanceof Closeable) {
                    ((Closeable)x).close();
                } else if (x instanceof Socket) {
                    ((Socket)x).close();
                } else if (x instanceof DatagramSocket) {
                    ((DatagramSocket)x).close();
                } else {
                    Log.d("cannot close: "+x);
                    throw new RuntimeException("cannot close "+x);
                }
            } catch (Throwable e) {
                Log.x(e);
            }
        }
    }
}
}

You must extend the regional options like this (code split on multiple lines for readability):

var options = $.extend(
    {},                                  // empty object
    $.datepicker.regional["fr"],         // fr regional
    { dateFormat: "d MM, y" /*, ... */ } // your custom options
);
$("#datepicker").datepicker(options);

The order of parameters is important because of the way jQuery.extend works. Two incorrect examples:

/*
 * This overwrites the global variable itself instead of creating a
 * customized copy of french regional settings
 */
$.extend($.datepicker.regional["fr"], { dateFormat: "d MM, y"});

/*
 * The desired dateFormat is overwritten by french regional 
 * settings' date format
 */
$.extend({ dateFormat: "d MM, y"}, $.datepicker.regional["fr"]);

PS: you also need to load the jQuery UI i18n files:

<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/i18n/jquery-ui-i18n.min.js">
</script>

I do not know C#, but with a little guesswork I think I understand what

foo : int {
    get { return getFoo(); }
    set { setFoo(newValue); }
}

does. It looks very similar to what you have in Swift, but it's not the same: in Swift you do not have the getFoo and setFoo. That is not a little difference: it means you do not have any underlying storage for your value.

Swift has stored and computed properties.

A computed property has get and may have set (if it's writable). But the code in the getter and setter, if they need to actually store some data, must do it in other properties. There is no backing storage.

A stored property, on the other hand, does have backing storage. But it does not have get and set. Instead it has willSet and didSet which you can use to observe variable changes and, eventually, trigger side effects and/or modify the stored value. You do not have willSet and didSet for computed properties, and you do not need them because for computed properties you can use the code in set to control changes.

Another variant:

private String getCharForNumber(int i) {
    if (i > 25 || i < 0) {
        return null;
    }
    return new Character((char) (i + 65)).toString();
}

"Proper way to declare custom exceptions in modern Python?"

This is fine, unless your exception is really a type of a more specific exception:

class MyException(Exception):
    pass

Or better (maybe perfect), instead of pass give a docstring:

class MyException(Exception):
    """Raise for my specific kind of exception"""

Subclassing Exception Subclasses

From the docs

Exception

All built-in, non-system-exiting exceptions are derived from this class. All user-defined exceptions should also be derived from this class.

That means that if your exception is a type of a more specific exception, subclass that exception instead of the generic Exception (and the result will be that you still derive from Exception as the docs recommend). Also, you can at least provide a docstring (and not be forced to use the pass keyword):

class MyAppValueError(ValueError):
    '''Raise when my specific value is wrong'''

Set attributes you create yourself with a custom __init__. Avoid passing a dict as a positional argument, future users of your code will thank you. If you use the deprecated message attribute, assigning it yourself will avoid a DeprecationWarning:

class MyAppValueError(ValueError):
    '''Raise when a specific subset of values in context of app is wrong'''
    def __init__(self, message, foo, *args):
        self.message = message # without this you may get DeprecationWarning
        # Special attribute you desire with your Error, 
        # perhaps the value that caused the error?:
        self.foo = foo         
        # allow users initialize misc. arguments as any other builtin Error
        super(MyAppValueError, self).__init__(message, foo, *args) 

There's really no need to write your own __str__ or __repr__. The builtin ones are very nice, and your cooperative inheritance ensures that you use it.

Critique of the top answer

Maybe I missed the question, but why not:

class MyException(Exception):
    pass

Again, the problem with the above is that in order to catch it, you'll either have to name it specifically (importing it if created elsewhere) or catch Exception, (but you're probably not prepared to handle all types of Exceptions, and you should only catch exceptions you are prepared to handle). Similar criticism to the below, but additionally that's not the way to initialize via super, and you'll get a DeprecationWarning if you access the message attribute:

Edit: to override something (or pass extra args), do this:

class ValidationError(Exception):
    def __init__(self, message, errors):

        # Call the base class constructor with the parameters it needs
        super(ValidationError, self).__init__(message)

        # Now for your custom code...
        self.errors = errors

That way you could pass dict of error messages to the second param, and get to it later with e.errors

It also requires exactly two arguments to be passed in (aside from the self.) No more, no less. That's an interesting constraint that future users may not appreciate.

To be direct - it violates Liskov substitutability.

I'll demonstrate both errors:

>>> ValidationError('foo', 'bar', 'baz').message

Traceback (most recent call last):
  File "<pyshell#10>", line 1, in <module>
    ValidationError('foo', 'bar', 'baz').message
TypeError: __init__() takes exactly 3 arguments (4 given)

>>> ValidationError('foo', 'bar').message
__main__:1: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6
'foo'

Compared to:

>>> MyAppValueError('foo', 'FOO', 'bar').message
'foo'

Its possible to do silent install on Android 6 and above. Using the function supplied in the answer by Boris Treukhov, ignore everything else in the post, root is not required either.

Install your app as device admin, you can have full kiosk mode with silent install of updates in the background.

WHERE AND SELECT Condition In Array Format Laravel

use DB;

$conditions = array(
    array('email', '=', '[email protected]')
);
$selected = array('id','name','email','mobile','created');
$result = DB::table('users')->select($selected)->where($conditions)->get();

You can simply write:

val mutableList = mutableListOf<Kolory>()

This is the most idiomatic way.

Alternative ways are

val mutableList : MutableList<Kolory> = arrayListOf()

or

val mutableList : MutableList<Kolory> = ArrayList()

This is exploiting the fact that java types like ArrayList are implicitly implementing the type MutableList via a compiler trick.

Apparently, Chrome addresses a key in Windows registry when it looks for a Java Environment. Since the plugin installs the JRE, this key is set to a JRE path and therefore needs to be edited if you want Chrome to work with the JDK.

1. Run the plugin installer anyways.
2. Start -> Run (Winkey+R) and then type in regedit to edit the registry.
3. Find HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin.
4. Export it as a reg file to say, your desktop (right-click and select Export).
5. Uninstall the JRE (Control Panel -> Add or Remove Programs). This should delete the key above, explaining the need to export it in the first place.
6. Open the reg file exported to your desktop with a text editor (such as Notepad++).

7. Edit "Path" so that it matches the corresponding dll inside your JDK installation:

   REGEDIT 4
   
   [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin]
   "Description"="Oracle® Next Generation Java™ Plug-In"
   "GeckoVersion"="1.9"
   
   "Path"="C:\Program Files (x86)\Java\jdk1.6.0_29\jre\bin\new_plugin\npjp2.dll"
   
   "ProductName"="Oracle® Java™ Plug-In"
   "Vendor"="Oracle Corp."
   "Version"="160_29"
   

8. Save file.

9. Double click modified reg file to add keys to your registry.

The REGEDIT 4 prefix at the top of the file might only be required for Windows 7 64-bit.

To write,

SharedPreferences prefs = PreferenceManager
        .getDefaultSharedPreferences(this);
JSONArray jsonArray = new JSONArray();
jsonArray.put(1);
jsonArray.put(2);
Editor editor = prefs.edit();
editor.putString("key", jsonArray.toString());
System.out.println(jsonArray.toString());
editor.commit();

To Read,

try {
    JSONArray jsonArray2 = new JSONArray(prefs.getString("key", "[]"));
    for (int i = 0; i < jsonArray2.length(); i++) {
         Log.d("your JSON Array", jsonArray2.getInt(i)+"");
    }
} catch (Exception e) {
    e.printStackTrace();
}

Other way to do same:

//Retrieve the values
Gson gson = new Gson();
String jsonText = Prefs.getString("key", null);
String[] text = gson.fromJson(jsonText, String[].class);  //EDIT: gso to gson


//Set the values
Gson gson = new Gson();
List<String> textList = new ArrayList<String>(data);
String jsonText = gson.toJson(textList);
prefsEditor.putString("key", jsonText);
prefsEditor.apply();

Using GSON in Java:

public void saveArrayList(ArrayList<String> list, String key){
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(activity);
    SharedPreferences.Editor editor = prefs.edit();
    Gson gson = new Gson();
    String json = gson.toJson(list);
    editor.putString(key, json);
    editor.apply();    

}

public ArrayList<String> getArrayList(String key){
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(activity);
    Gson gson = new Gson();
    String json = prefs.getString(key, null);
    Type type = new TypeToken<ArrayList<String>>() {}.getType();
    return gson.fromJson(json, type);
}

Using GSON in Kotlin

fun saveArrayList(list: java.util.ArrayList<String?>?, key: String?) {
    val prefs: SharedPreferences = PreferenceManager.getDefaultSharedPreferences(activity)
    val editor: Editor = prefs.edit()
    val gson = Gson()
    val json: String = gson.toJson(list)
    editor.putString(key, json)
    editor.apply()
}

fun getArrayList(key: String?): java.util.ArrayList<String?>? {
    val prefs: SharedPreferences = PreferenceManager.getDefaultSharedPreferences(activity)
    val gson = Gson()
    val json: String = prefs.getString(key, null)
    val type: Type = object : TypeToken<java.util.ArrayList<String?>?>() {}.getType()
    return gson.fromJson(json, type)
}

You can run the pipenv command with the --rm option as in:

pipenv --rm

This will remove the virtualenv created for you under ~/.virtualenvs

See https://pipenv.kennethreitz.org/en/latest/cli/#cmdoption-pipenv-rm

Environ() gets you the value of any environment variable. These can be found by doing the following command in the Command Prompt:

set

If you wanted to get the username, you would do:

Environ("username")

If you wanted to get the fully qualified name, you would do:

Environ("userdomain") & "\" & Environ("username")

BTW, serialization is not the same as refl, as some objects may provide overridden serialization methods (readObject/writeObject) and they can be buggy

Cross browser solution for printing pdf from base64 string:

• Chrome: print window is opened
• FF: new tab with pdf is opened
• IE11: open/save prompt is opened

.

const blobPdfFromBase64String = base64String => {
   const byteArray = Uint8Array.from(
     atob(base64String)
       .split('')
       .map(char => char.charCodeAt(0))
   );
  return new Blob([byteArray], { type: 'application/pdf' });
};

const isIE11 = !!(window.navigator && window.navigator.msSaveOrOpenBlob); // or however you want to check it

const printPDF = blob => {
   try {
     isIE11
       ? window.navigator.msSaveOrOpenBlob(blob, 'documents.pdf')
       : printJS(URL.createObjectURL(blob)); // http://printjs.crabbly.com/
   } catch (e) {
     throw PDFError;
   }
};

printPDF(blobPdfFromBase64String(base64String))

BONUS - Opening blob file in new tab for IE11

If you're able to do some preprocessing of the base64 string on the server you could expose it under some url and use the link in printJS :)

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

This works for me

var options = $(dropdown).find('option');
var targetOption = $(options).filter(
function () { return $(this).html() == value; });

console.log($(targetOption).val());

Thanks for all the posts.

The question is answered but providing a command line for illustration. This worked for me when I was trying a as simple as possible test to connect to network mode derby.

• Driver loaded in app with:Class.forName("org.apache.derby.jdbc.ClientDriver").newInstance();

• The connection URL was: "jdbc:derby://localhost:1527/myDB;create=true"

• I ran my app using: java -classpath derbyclient.jar:. myAppClass

All inputs should be replaced with custom directive that reads a single global variable to toggle readonly status.

// template
<your-input [readonly]="!childmessage"></your-input>

// component value
childmessage = false;

After not finding a modern and comprehensive solution here, I have written an arrow function (without regex) to solve the formatting problem and it allows the caller to provide number of fraction digits as well as the period and thousand separator for Europe and rest of the world.

Examples:

numberFormatter(1234567890.123456) => 1,234,567,890
numberFormatter(1234567890.123456, 4) => 1,234,567,890.1235
numberFormatter(1234567890.123456, 4, '.', ',') => 1.234.567.890,1235 Europe

Here is the function written in ES6 (modern syntax):

const numberFormatter = (number, fractionDigits = 0, thousandSeperator = ',', fractionSeperator = '.') => {
    if (number!==0 && !number || !Number.isFinite(number)) return number
    const frDigits = Number.isFinite(fractionDigits)? Math.min(Math.max(fractionDigits, 0), 7) : 0
    const num = number.toFixed(frDigits).toString()

    const parts = num.split('.')
    let digits = parts[0].split('').reverse()
    let sign = ''
    if (num < 0) {sign = digits.pop()}
    let final = []
    let pos = 0

    while (digits.length > 1) {
        final.push(digits.shift())
        pos++
        if (pos % 3 === 0) {final.push(thousandSeperator)}
    }
    final.push(digits.shift())
    return `${sign}${final.reverse().join('')}${frDigits > 0 ? fractionSeperator : ''}${frDigits > 0 && parts[1] ? parts[1] : ''}`
}

It has been tested for negative, bad input and NaN cases. If the input is NaN then it simply returns it.

var request = require('request');
 function updateClient(postData){
            var clientServerOptions = {
                uri: 'http://'+clientHost+''+clientContext,
                body: JSON.stringify(postData),
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json'
                }
            }
            request(clientServerOptions, function (error, response) {
                console.log(error,response.body);
                return;
            });
        }

For this to work, your server must be something like:

var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json())

var port = 9000;

app.post('/sample/put/data', function(req, res) {
    console.log('receiving data ...');
    console.log('body is ',req.body);
    res.send(req.body);
});

// start the server
app.listen(port);
console.log('Server started! At http://localhost:' + port);

If you have an Order class, adding a property that references another class in your model, for instance Customer should be enough to let EF know there's a relationship in there:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    public virtual Customer Customer { get; set; }
}

You can always set the FK relation explicitly:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    [ForeignKey("Customer")]
    public string CustomerID { get; set; }
    public virtual Customer Customer { get; set; }
}

The ForeignKeyAttribute constructor takes a string as a parameter: if you place it on a foreign key property it represents the name of the associated navigation property. If you place it on the navigation property it represents the name of the associated foreign key.

What this means is, if you where to place the ForeignKeyAttribute on the Customer property, the attribute would take CustomerID in the constructor:

public string CustomerID { get; set; }
[ForeignKey("CustomerID")]
public virtual Customer Customer { get; set; }

EDIT based on Latest Code You get that error because of this line:

[ForeignKey("Parent")]
public Patient Patient { get; set; }

EF will look for a property called Parent to use it as the Foreign Key enforcer. You can do 2 things:

1) Remove the ForeignKeyAttribute and replace it with the RequiredAttribute to mark the relation as required:

[Required]
public virtual Patient Patient { get; set; }

Decorating a property with the RequiredAttribute also has a nice side effect: The relation in the database is created with ON DELETE CASCADE.

I would also recommend making the property virtual to enable Lazy Loading.

2) Create a property called Parent that will serve as a Foreign Key. In that case it probably makes more sense to call it for instance ParentID (you'll need to change the name in the ForeignKeyAttribute as well):

public int ParentID { get; set; }

In my experience in this case though it works better to have it the other way around:

[ForeignKey("Patient")]
public int ParentID { get; set; }

public virtual Patient Patient { get; set; }

This is definitely not the best way to do this but, I got it done by doing something like following.

String imageName = "my_image.png";
String replace = imageName.replace('.','~');
String[] split = replace.split("~");

System.out.println("Image name : " + split[0]);
System.out.println("Image extension : " + split[1]);

Output,

If you work in MS Visual Studio just do following

1. Put WSDL file and XSD file at the same folder.

2. Correct WSDL file like this YourSchemeFile.xsd

3. Use visual Studio using this great example How to generate service reference with only physical wsdl file

Notice that you have to put the path to your WSDL file manually. There is no way to use Open File dialog box out there.

Here is a solution using the javax.crypto library and the apache commons codec library for encoding and decoding in Base64:

import java.security.spec.KeySpec;
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.DESedeKeySpec;
import org.apache.commons.codec.binary.Base64;

public class TrippleDes {

    private static final String UNICODE_FORMAT = "UTF8";
    public static final String DESEDE_ENCRYPTION_SCHEME = "DESede";
    private KeySpec ks;
    private SecretKeyFactory skf;
    private Cipher cipher;
    byte[] arrayBytes;
    private String myEncryptionKey;
    private String myEncryptionScheme;
    SecretKey key;

    public TrippleDes() throws Exception {
        myEncryptionKey = "ThisIsSpartaThisIsSparta";
        myEncryptionScheme = DESEDE_ENCRYPTION_SCHEME;
        arrayBytes = myEncryptionKey.getBytes(UNICODE_FORMAT);
        ks = new DESedeKeySpec(arrayBytes);
        skf = SecretKeyFactory.getInstance(myEncryptionScheme);
        cipher = Cipher.getInstance(myEncryptionScheme);
        key = skf.generateSecret(ks);
    }


    public String encrypt(String unencryptedString) {
        String encryptedString = null;
        try {
            cipher.init(Cipher.ENCRYPT_MODE, key);
            byte[] plainText = unencryptedString.getBytes(UNICODE_FORMAT);
            byte[] encryptedText = cipher.doFinal(plainText);
            encryptedString = new String(Base64.encodeBase64(encryptedText));
        } catch (Exception e) {
            e.printStackTrace();
        }
        return encryptedString;
    }


    public String decrypt(String encryptedString) {
        String decryptedText=null;
        try {
            cipher.init(Cipher.DECRYPT_MODE, key);
            byte[] encryptedText = Base64.decodeBase64(encryptedString);
            byte[] plainText = cipher.doFinal(encryptedText);
            decryptedText= new String(plainText);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return decryptedText;
    }


    public static void main(String args []) throws Exception
    {
        TrippleDes td= new TrippleDes();

        String target="imparator";
        String encrypted=td.encrypt(target);
        String decrypted=td.decrypt(encrypted);

        System.out.println("String To Encrypt: "+ target);
        System.out.println("Encrypted String:" + encrypted);
        System.out.println("Decrypted String:" + decrypted);

    }

}

Running the above program results with the following output:

String To Encrypt: imparator
Encrypted String:FdBNaYWfjpWN9eYghMpbRA==
Decrypted String:imparator

A simple solution for me was to go to Properties -> Java Build Path -> Order and Export, then check the Apache Tomcat library. This is assumes you've already set Tomcat as your deployment target and are still getting the error.

Because of the definition of the semantics of nth-child, I don't see how this is possible without including the length of the list of elements involved. The point of the semantics is to allow segregation of a bunch of child elements into repeating groups (edit - thanks BoltClock) or into a first part of some fixed length, followed by "the rest". You sort-of want the opposite of that, which is what nth-last-child gives you.

Try this

$date = Carbon::parse(date_format($youttimestring,'d/m/Y H:i:s'));
echo $date;

If you installed as admin ( and meant for all users )

C:\ProgramData\Anaconda3\Scripts\anaconda.exe

If you install as a normal user

C:\Users\User-Name\AppData\Local\Continuum\Anaconda2\Scripts\anaconda.exe

I think the bulletproof way is:

if (typeof $.cookie('token') === 'undefined'){
 //no cookie
} else {
 //have cookie
}

Checking the type of a null, empty or undefined var always returns 'undefined'

Edit: You can get there even easier:

if (!!$.cookie('token')) {
 // have cookie
} else {
 // no cookie
}

!! will turn the falsy values to false. Bear in mind that this will turn 0 to false!

How about using self-joining:

CREATE TABLE mytable (person, groupname, age);
INSERT INTO mytable VALUES('Bob',1,32);
INSERT INTO mytable VALUES('Jill',1,34);
INSERT INTO mytable VALUES('Shawn',1,42);
INSERT INTO mytable VALUES('Jake',2,29);
INSERT INTO mytable VALUES('Paul',2,36);
INSERT INTO mytable VALUES('Laura',2,39);

SELECT a.* FROM mytable AS a
  LEFT JOIN mytable AS a2 
    ON a.groupname = a2.groupname AND a.age <= a2.age
GROUP BY a.person
HAVING COUNT(*) <= 2
ORDER BY a.groupname, a.age DESC;

gives me:

a.person    a.groupname  a.age     
----------  -----------  ----------
Shawn       1            42        
Jill        1            34        
Laura       2            39        
Paul        2            36      

I was strongly inspired by the answer from Bill Karwin to Select top 10 records for each category

Also, I'm using SQLite, but this should work on MySQL.

Another thing: in the above, I replaced the group column with a groupname column for convenience.

Edit:

Following-up on the OP's comment regarding missing tie results, I incremented on snuffin's answer to show all the ties. This means that if the last ones are ties, more than 2 rows can be returned, as shown below:

.headers on
.mode column

CREATE TABLE foo (person, groupname, age);
INSERT INTO foo VALUES('Paul',2,36);
INSERT INTO foo VALUES('Laura',2,39);
INSERT INTO foo VALUES('Joe',2,36);
INSERT INTO foo VALUES('Bob',1,32);
INSERT INTO foo VALUES('Jill',1,34);
INSERT INTO foo VALUES('Shawn',1,42);
INSERT INTO foo VALUES('Jake',2,29);
INSERT INTO foo VALUES('James',2,15);
INSERT INTO foo VALUES('Fred',1,12);
INSERT INTO foo VALUES('Chuck',3,112);


SELECT a.person, a.groupname, a.age 
FROM foo AS a 
WHERE a.age >= (SELECT MIN(b.age)
                FROM foo AS b 
                WHERE (SELECT COUNT(*)
                       FROM foo AS c
                       WHERE c.groupname = b.groupname AND c.age >= b.age) <= 2
                GROUP BY b.groupname)
ORDER BY a.groupname ASC, a.age DESC;

gives me:

person      groupname   age       
----------  ----------  ----------
Shawn       1           42        
Jill        1           34        
Laura       2           39        
Paul        2           36        
Joe         2           36        
Chuck       3           112      

I worked so much, I hope my effort might help you out.

Just paste this into your SSMS and press F5:

Declare @Object as Int;
DECLARE @hr  int
Declare @json as table(Json_Table nvarchar(max))

Exec @hr=sp_OACreate 'MSXML2.ServerXMLHTTP.6.0', @Object OUT;
IF @hr <> 0 EXEC sp_OAGetErrorInfo @Object
Exec @hr=sp_OAMethod @Object, 'open', NULL, 'get',
                 'http://overpass-api.de/api/interpreter?data=[out:json];area[name=%22Auckland%22]-%3E.a;(node(area.a)[amenity=cinema];way(area.a)[amenity=cinema];rel(area.a)[amenity=cinema];);out;', --Your Web Service Url (invoked)
                 'false'
IF @hr <> 0 EXEC sp_OAGetErrorInfo @Object
Exec @hr=sp_OAMethod @Object, 'send'
IF @hr <> 0 EXEC sp_OAGetErrorInfo @Object
Exec @hr=sp_OAMethod @Object, 'responseText', @json OUTPUT
IF @hr <> 0 EXEC sp_OAGetErrorInfo @Object

INSERT into @json (Json_Table) exec sp_OAGetProperty @Object, 'responseText'
-- select the JSON string
select * from @json
-- Parse the JSON string
SELECT * FROM OPENJSON((select * from @json), N'$.elements')
WITH (   
      [type] nvarchar(max) N'$.type'   ,
      [id]   nvarchar(max) N'$.id',
      [lat]   nvarchar(max) N'$.lat',
      [lon]   nvarchar(max) N'$.lon',
      [amenity]   nvarchar(max) N'$.tags.amenity',
      [name]   nvarchar(max) N'$.tags.name'     
)
EXEC sp_OADestroy @Object

This query will give you 3 results:

1. Catch the error in case something goes wrong (don't panic, it will always show you an error above 4000 characters because NVARCHAR(MAX) can only store till 4000 characters)

2. Put the JSON into a string (which is what we want)

3. BONUS: parse the JSON and nicely store the data into a table (how cool is that?)

For anyone else having the same problem, I figured it out myself.

    <html>_x000D_
      <body>_x000D_
        <form target="_blank" action="https://website.com/action.php" method="POST">_x000D_
          <input type="hidden" name="fullname" value="Sam" />_x000D_
          <input type="hidden" name="city" value="Dubai&#32;" />_x000D_
          <input onclick="window.location.href = 'https://website.com/my-account';" type="submit" value="Submit request" />_x000D_
        </form>_x000D_
      </body>_x000D_
    </html>

All I had to do was add the target="_blank" attribute to inline on form to open the response in a new page and redirect the other page using onclick on the submit button.

You can't focus on a div. You can only focus on an input element in that div. Also, you need to use element.focus() instead of display()

I used this way to take the last record for each user that I have on my table. It was a query to get last location for salesman as per recent time detected on PDA devices.

CREATE FUNCTION dbo.UsersLocation()
RETURNS TABLE
AS
RETURN
Select GS.UserID, MAX(GS.UTCDateTime) 'LastDate'
From USERGPS GS
where year(GS.UTCDateTime) = YEAR(GETDATE()) 
Group By GS.UserID
GO
select  gs.UserID, sl.LastDate, gs.Latitude , gs.Longitude
        from USERGPS gs
        inner join USER s on gs.SalesManNo = s.SalesmanNo 
        inner join dbo.UsersLocation() sl on gs.UserID= sl.UserID and gs.UTCDateTime = sl.LastDate 
        order by LastDate desc

If you are converting price (in string) to decimal price then....

from decimal import Decimal

price = "14000,45"
price_in_decimal = Decimal(price.replace(',','.'))

No need for the replace if your strings already use dots as a decimal separator

For less use -u to display carriage returns (^M) and backspaces (^H), or -U to show the previous and tabs (^I) for example:

$ awk 'BEGIN{print "foo\bbar\tbaz\r\n"}' | less -U 
foo^Hbar^Ibaz^M

(END)

Without the -U switch the output would be:

fobar   baz

(END)

See man less for more exact description on the features.

A bit late to the table here, but in c# (vs2013) you don't need to use column names either, in fact a lot of the extra work that some people propose is completely unnecessary.

The column is actually created as an member of the container (the form, or usercontrol that you've put the DataGridView into). From the designer code (the stuff you're not supposed to edit except when the designer breaks something), you'd see something like:

this.curvesList.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {
        this.enablePlot,
        this.desc,
        this.unit,
        this.min,
        this.max,
        this.color});

...

//
// color
// 
this.color.HeaderText = "Colour";
this.color.MinimumWidth = 40;
this.color.Name = "color";
this.color.ReadOnly = true;
this.color.Width = 40;

...

private System.Windows.Forms.DataGridViewButtonColumn color;

So in the CellContentClick handler, apart from ensuring that the row index is not 0, you just need to check whether the clicked column is in fact the one you want by comparing object references:

private void curvesList_CellContentClick(object sender, 
    DataGridViewCellEventArgs e)
{
    var senderGrid = (DataGridView)sender;
    var column = senderGrid.Columns[e.ColumnIndex];
    if (e.RowIndex >= 0)
    {
        if ((object)column == (object)color)
        {
            colorDialog.Color = Color.Blue;
                colorDialog.ShowDialog();
        }
    }
}

Note that the beauty of this is that any name changes will be caught by the compiler. If you index with a text name that changes, or that you capitalize incorrectly, you're bound for runtime issues. Here you actually use the name of an object, that the designer creates based on the name you supplied. But any mismatch will be brought to your attention by the compiler.

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

This is the best practice. This way you will get the variables from GET method as well as POST method

    public function index(Request $request) {
            $data=$request->all();
            dd($data);
    }
//OR if you want few of them then
    public function index(Request $request) {
            $data=$request->only('id','name','etc');
            dd($data);
    }
//OR if you want all except few then
    public function index(Request $request) {
            $data=$request->except('__token');
            dd($data);
    }

Strictly sticking to the question, the Python code (+ pseudo-code) would be:

import os
file_path = r"<path to your file>"
if os.stat(file_path).st_size > 0:
    <send an email to somebody>
else:
    <continue to other things>

When initializing your repository, skip the git command that contains

-u

and it shouldn't be an issue.

Another to answer this question available here answered by @nilesh https://stackoverflow.com/a/19934852/2079692

public void setAttributeValue(WebElement elem, String value){
    JavascriptExecutor js = (JavascriptExecutor) driver;
    js.executeScript("arguments[0].setAttribute(arguments[1],arguments[2])",
        elem, "value", value
    );
}

this takes advantage of selenium findElementBy function where xpath can be used also.

I got this error when trying to log to an NLog target that no longer existed.

You can use assertThrows(), which allows you to test multiple exceptions within the same test. With support for lambdas in Java 8, this is the canonical way to test for exceptions in JUnit.

Per the JUnit docs:

import static org.junit.jupiter.api.Assertions.assertThrows;

@Test
void exceptionTesting() {
    MyException thrown = assertThrows(
           MyException.class,
           () -> myObject.doThing(),
           "Expected doThing() to throw, but it didn't"
    );

    assertTrue(thrown.getMessage().contains("Stuff"));
}

Version 12.5 of wkhtmltopdf only lists DEB files on their download page now. Being a mac user and not knowing much linux or what DEB files were I couldn't use the solutions posted.

This page helped me get past the knew twist of downloading a DEB file: http://www.g-loaded.eu/2008/01/28/how-to-extract-rpm-or-deb-packages/

Basically what I did was:

1. Downloaded from https://wkhtmltopdf.org/downloads.html
2. Unzipped the DEB file.
3. Unzipped data.tar.xz
4. Uploaded the binary in the unzipped 'usr' folder from step 3 (usr/local/bin/wkhtmltopdf)

Then I found out that the 'exec' function was disabled on my host. So make sure you can specifically run 'exec' if you're using PHP to run this. "Can I run the wkhtmltopdf binary" isn't specific enough. My fault.

I also face a situation when I needed to return a top result but also wanted to get the total rows that where matching the query. i finaly get to this solution:

   public string Format(SelectQuery selectQuery)
    {
      string result;

      if (string.IsNullOrWhiteSpace(selectQuery.WherePart))
      {
        result = string.Format(
@"
declare @maxResult  int;
set @maxResult = {0};

WITH Total AS
(
SELECT count(*) as [Count] FROM {2}
)
SELECT top (@maxResult) Total.[Count], {1} FROM Total, {2}", m_limit.To, selectQuery.SelectPart, selectQuery.FromPart);
      }
      else
      {
        result = string.Format(
@"
declare @maxResult  int;
set @maxResult = {0};

WITH Total AS
(
SELECT count(*) as [Count] FROM {2} WHERE {3}
)
SELECT top (@maxResult) Total.[Count], {1} FROM Total, {2} WHERE {3}", m_limit.To, selectQuery.SelectPart, selectQuery.FromPart, selectQuery.WherePart);
      }

      if (!string.IsNullOrWhiteSpace(selectQuery.OrderPart))
        result = string.Format("{0} ORDER BY {1}", result, selectQuery.OrderPart);

      return result;
    }

  String dateTime="15-3-2019 09:50 AM" //time should be two digit like 08,09,10 
   DateTimeFormatter dtf  = DateTimeFormatter.ofPattern("dd-MM-yyyy hh:mm a");
        LocalDateTime zdt  = LocalDateTime.parse(dateTime,dtf);
        LocalDateTime now = LocalDateTime.now();
        ZoneId zone = ZoneId.of("Asia/Kolkata");
        ZoneOffset zoneOffSet = zone.getRules().getOffset(now);
        long a= zdt.toInstant(zoneOffSet).toEpochMilli();
        Log.d("time","---"+a);

you can get zone id form this a link!

I use this code

$variable = array();

if( count( $variable ) == 0 )
{
    echo "Array is Empty";
}
else
{
    echo "Array is not Empty";
}

But note that if the array has a large number of keys, this code will spend much time counting them, as compared to the other answers here.

set encoding=utf-8  " The encoding displayed.
set fileencoding=utf-8  " The encoding written to file.

You may as well set both in your ~/.vimrc if you always want to work with utf-8.

the discussion and answer here was massively helpful to me:

psql: FATAL: database "<user>" does not exist

You can use CURL for this purpose see the example code:

$url = "your url";    
$content = json_encode("your data to be sent");

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
        array("Content-type: application/json"));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);

$json_response = curl_exec($curl);

$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

if ( $status != 201 ) {
    die("Error: call to URL $url failed with status $status, response $json_response, curl_error " . curl_error($curl) . ", curl_errno " . curl_errno($curl));
}


curl_close($curl);

$response = json_decode($json_response, true);

I think the only way to do this is to run another machine in parallel and use that machine to issue commands to your android box similar to how you would with a phone. If you have issues with the IP changing you can reserve an ip on your router and have the machine grab that one instead of asking the routers DHCP for one. This way you can ping the machine and figure out if it's done rebooting to continue the script.

It depends on how you want to use your String. This can help:

String total =  Integer.toString(123) + Double.toString(456.789);

It is actually very easy:

just use:

.icon-name{
color: #0C0;}

For example:

.icon-compass{
color: #C30;}

That's it.

my way to reset all submodules (WITHOUT detaching & keeping their "master" branch):

git submodule foreach 'git checkout master && git reset --hard $sha1'

You can use !!, but if you want to do it recursively then below is one way to do it:

dataAt :: Int -> [a] -> a
dataAt _ [] = error "Empty List!"
dataAt y (x:xs)  | y <= 0 = x
                 | otherwise = dataAt (y-1) xs

When working with local packages, the only way I found to reliably regenerate the package-lock.json file is to delete it, as well as in the linked modules and all corresponding node_modules folders and let it be regenerated with npm i

As shaishab roy says, in the cheat sheet you can find the answer.

But in his answer, the given response was :

{path: '/home/...', name: 'Home', component: HomeComponent}
{path: '/', redirectTo: ['Home']},
{path: '/user/...', name: 'User', component: UserComponent},
{path: '/404', name: 'NotFound', component: NotFoundComponent},

{path: '/*path', redirectTo: ['NotFound']}

For some reasons, it doesn't works on my side, so I tried instead :

{path: '/**', redirectTo: ['NotFound']}

and it works. Be careful and don't forget that you need to put it at the end, or else you will often have the 404 error page ;).

 var employee =  (from res in _db.EMPLOYEEs
 where (res.EMAIL == givenInfo || res.USER_NAME == givenInfo)
 select new {res.EMAIL, res.USERNAME} );

OR you can use

 var employee =  (from res in _db.EMPLOYEEs
 where (res.EMAIL == givenInfo || res.USER_NAME == givenInfo)
 select new {email=res.EMAIL, username=res.USERNAME} );

Explanation :

1. Select employee from the db as res.

2. Filter the employee details as per the where condition.

3. Select required fields from the employee object by creating an Anonymous object using new { }

Another variation

.blink {_x000D_
    -webkit-animation: blink 1s step-end infinite;_x000D_
            animation: blink 1s step-end infinite;_x000D_
}_x000D_
@-webkit-keyframes blink { 50% { visibility: hidden; }}_x000D_
        @keyframes blink { 50% { visibility: hidden; }}

This is <span class="blink">blink</span>

How about

`SELECT 
    my_distinct_column,
    max(col1),
    max(col2),
    max(col3)
    ...
 FROM
    my_table 
 GROUP BY 
    my_distinct_column`

This was considered for inclusion in C++/1x, but was dropped (this is a correction to what I said earlier).

It would be less useful in C++ anyway since we already have std::vector to fill this role.

It could be useful for someone.

We recently had the same issue for Android 9, but we only needed to display some Urls within WebView, nothing very special. So adding android:usesCleartextTraffic="true" to Manifest worked, but we didn't want to compromise security of the whole app for this. So the fix was in changing links from http to https

I would suggest using R and the package RSQLite

#install.packages("RSQLite") #perhaps needed
library("RSQLite")

# connect to the sqlite file
sqlite    <- dbDriver("SQLite")
exampledb <- dbConnect(sqlite,"database.sqlite")

dbListTables(exampledb)

In Python self is the conventional name given to the first argument of instance methods of classes, which is always the instance the method was called on:

class A(object):
  def f(self):
    print self

a = A()
a.f()

Will give you something like

<__main__.A object at 0x02A9ACF0>

If you're on Django 1.10 or newer AND Postgres as your database, you can use ArrayField. It's better to use than django-taggit or other alternatives, as it's native to the Django framework. https://docs.djangoproject.com/en/3.1/ref/contrib/postgres/fields/#arrayfield

from django.db import models
from django.contrib.postgres.fields import ArrayField

class ChessBoard(models.Model):
    board = ArrayField(
        ArrayField(
            models.CharField(max_length=10, blank=True),
            size=8,
        ),
        size=8,
    )

If you're on Django 3.1 or newer they've added support for JSONField with most database backends (MariaDB 10.2.7+, MySQL 5.7.8+, Oracle, PostgreSQL, and SQLite 3.9.0+). You can use this to store your Array!

https://docs.djangoproject.com/en/3.1/ref/models/fields/#jsonfield

from django.db import models

class ChessBoard(models.Model):
    list_of_pieces = models.JSONField()

This is the problem that is occurring,

if the JAR file was loaded from "C:\java\apps\appli.jar", and your manifest file has the Class-Path: reference "lib/other.jar", the class loader will look in "C:\java\apps\lib\" for "other.jar". It won't look at the JAR file entry "lib/other.jar".

Solution:-

1. Right click on project, Select Export.
2. Select Java Folder and in it select Runnable JAR File instead of JAR file.
3. Select the proper options and in the Library Handling section select the 3rd option i.e. (Copy required libraries into a sub-folder next to the generated JAR).

[ EDIT = 3rd option generates a folder in addition to the jar, 2nd option ("Package required libraries into generated JAR") can also be used as you have the jar. ]

4. Click finish and your JAR is created at the specified position along with a folder that contains the JARS mentioned in the manifest file.

5. open the terminal,give the proper path to your jar and run it using this command java -jar abc.jar

   Now what will happen is the class loader will look in the correct folder for the referenced JARS since now they are present in the same folder that contains your app JAR..There is no "java.lang.NoClassDefFoundError" exception thrown now.

This worked for me... Hope it works for you too!!!

Another alternative is the typeof operator:

if (typeof console == "undefined") {
    this.console = {log: function() {}};
}

Yet another alternative is to use a logging library, such as my own log4javascript.

ALTER TABLE foobar_data MODIFY COLUMN col VARCHAR(255) NOT NULL DEFAULT '{}';

A second possibility which does the same (thanks to juergen_d):

ALTER TABLE foobar_data CHANGE COLUMN col col VARCHAR(255) NOT NULL DEFAULT '{}';

For older versions of Python where the next built-in doesn't exist:

(x for x in range(10) if x > 3).next()

For Angular9+, according to this, you can use:

.mat-select-panel {
    background: red;
    ....
}

Demo

1. Use ::ng-deep:

Use the /deep/ shadow-piercing descendant combinator to force a style down through the child component tree into all the child component views. The /deep/ combinator works to any depth of nested components, and it applies to both the view children and content children of the component. Use /deep/, >>> and ::ng-deep only with emulated view encapsulation. Emulated is the default and most commonly used view encapsulation. For more information, see the Controlling view encapsulation section. The shadow-piercing descendant combinator is deprecated and support is being removed from major browsers and tools. As such we plan to drop support in Angular (for all 3 of /deep/, >>> and ::ng-deep). Until then ::ng-deep should be preferred for a broader compatibility with the tools.

CSS:

::ng-deep .mat-select-content{
    width:2000px;
    background-color: red;
    font-size: 10px;   
}

DEMO

2. Use ViewEncapsulation

... component CSS styles are encapsulated into the component's view and don't affect the rest of the application. To control how this encapsulation happens on a per component basis, you can set the view encapsulation mode in the component metadata. Choose from the following modes: .... None means that Angular does no view encapsulation. Angular adds the CSS to the global styles. The scoping rules, isolations, and protections discussed earlier don't apply. This is essentially the same as pasting the component's styles into the HTML.

None value is what you will need to break the encapsulation and set material style from your component. So can set on the component's selector:

Typscript:

  import {ViewEncapsulation } from '@angular/core';
  ....
  @Component({
        ....
        encapsulation: ViewEncapsulation.None
 })  

CSS

.mat-select-content{
    width:2000px;
    background-color: red;
    font-size: 10px;
}

DEMO

3. Set class style in style.css

This time you have to 'force' styles with !important too.

style.css

 .mat-select-content{
   width:2000px !important;
   background-color: red !important;
   font-size: 10px !important;
 } 

DEMO

4. Use inline style

<mat-option style="width:2000px; background-color: red; font-size: 10px;" ...>

DEMO

I ran across a site a few weeks back. This is a working example of the first column locked but it is not browser compatible with Firefox. I didn't do a lot of checking around but it seems it only works in IE. There are some notes the author provided along with it that you can read.

Lock the First column: http://home.tampabay.rr.com/bmerkey/examples/locked-column-csv.html

Let me know if you need the Javascript to lock the Table headers too.

You use the alter table ... change ... method, for example:

mysql> create table yar (id int);
Query OK, 0 rows affected (0.01 sec)

mysql> insert into yar values(5);
Query OK, 1 row affected (0.01 sec)

mysql> alter table yar change id id varchar(255);
Query OK, 1 row affected (0.03 sec)
Records: 1  Duplicates: 0  Warnings: 0

mysql> desc yar;
+-------+--------------+------+-----+---------+-------+
| Field | Type         | Null | Key | Default | Extra |
+-------+--------------+------+-----+---------+-------+
| id    | varchar(255) | YES  |     | NULL    |       |
+-------+--------------+------+-----+---------+-------+
1 row in set (0.00 sec)

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 */);

To plot text on a ggplot you use the geom_text. But I find it helpful to summarise the data first using ddply

dfl <- ddply(df, .(x), summarize, y=length(x))
str(dfl)

Since the data is pre-summarized, you need to remember to change add the stat="identity" parameter to geom_bar:

ggplot(dfl, aes(x, y=y, fill=x)) + geom_bar(stat="identity") +
    geom_text(aes(label=y), vjust=0) +
    opts(axis.text.x=theme_blank(),
        axis.ticks=theme_blank(),
        axis.title.x=theme_blank(),
        legend.title=theme_blank(),
        axis.title.y=theme_blank()
)

pickle module is part of the standard library in Python for a very long time now so there is no need to install it via pip. I wonder if you IDE or command line is not messed up somehow so that it does not find python installation path. Please check if your %PATH% contains a path to python (e.g. C:\Python36\ or something similar) or if your IDE correctly detects root path where Python is installed.

How can I decrypt MySQL passwords

You can't really because they are hashed and not encrypted.

Here's the essence of the PASSWORD function that current MySQL uses. You can execute it from the sql terminal:

mysql> SELECT SHA1(UNHEX(SHA1("password")));

+------------------------------------------+
| SHA1(UNHEX(SHA1("password")))            |
+------------------------------------------+
| 2470C0C06DEE42FD1618BB99005ADCA2EC9D1E19 |
+------------------------------------------+
1 row in set (0.00 sec)

How can I change or retrieve these?

If you are having trouble logging in on a debian or ubuntu system, first try this (thanks to tohuwawohu at https://askubuntu.com/questions/120718/cant-log-to-mysql):

$ sudo cat /etc/mysql/debian.conf | grep -i password
...
password: QWERTY12345...

Then, log in with the debian maintenance user:

$ mysql -u debian-sys-maint -p
password:

Finally, change the user's password:

mysql> UPDATE mysql.user SET Password=PASSWORD('new password') WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> quit;

When I look in the PHPmyAdmin the passwords are encrypted

Related, if you need to dump the user database for the relevant information, try:

mysql> SELECT User,Host,Password FROM mysql.user;
+------------------+-----------+----------------------+
| User             | Host      | Password             |
+------------------+-----------+----------------------+
| root             | localhost | *0123456789ABCDEF... |
| root             | 127.0.0.1 | *0123456789ABCDEF... |
| root             | ::1       | *0123456789ABCDEF... |
| debian-sys-maint | localhost | *ABCDEF0123456789... |
+------------------+-----------+----------------------+

And yes, those passwords are NOT salted. So an attacker can prebuild the tables and apply them to all MySQL installations. In addition, the adversary can learn which users have the same passwords.

Needles to say, the folks at mySQL are not following best practices. John Steven did an excellent paper on Password Storage Best Practice at OWASP's Password Storage Cheat Sheet. In fairness to the MySQL folks, they may be doing it because of pain points in the architecture, design or implementation (I simply don't know).

If you use the PASSWORD and UPDATE commands and the change does not work, then see http://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html. Even though the page is named "resetting permissions", its really about how to change a password. (Its befuddling the MySQL password change procedure is so broken that you have to jump through the hoops, but it is what it is).

You could also use:

<body onload="focusOnInput()">
    <form name="passwordForm" action="verify.php" method="post">
        <input name="passwordInput" type="password" />
    </form>
</body>

And then in your JavaScript:

function focusOnInput() {
    document.forms["passwordForm"]["passwordInput"].focus();
}

Swift version of @onegray's answer

protocol RequestsNavigationPopVerification {
    var confirmationTitle: String { get }
    var confirmationMessage: String { get }
}

extension RequestsNavigationPopVerification where Self: UIViewController {
    var confirmationTitle: String {
        return "Go back?"
    }

    var confirmationMessage: String {
        return "Are you sure?"
    }
}

final class NavigationController: UINavigationController {

    func navigationBar(navigationBar: UINavigationBar, shouldPopItem item: UINavigationItem) -> Bool {

        guard let requestsPopConfirm = topViewController as? RequestsNavigationPopVerification else {
            popViewControllerAnimated(true)
            return true
        }

        let alertController = UIAlertController(title: requestsPopConfirm.confirmationTitle, message: requestsPopConfirm.confirmationMessage, preferredStyle: .Alert)

        alertController.addAction(UIAlertAction(title: "Cancel", style: .Cancel) { _ in
            dispatch_async(dispatch_get_main_queue(), {
                let dimmed = navigationBar.subviews.flatMap { $0.alpha < 1 ? $0 : nil }
                UIView.animateWithDuration(0.25) {
                    dimmed.forEach { $0.alpha = 1 }
                }
            })
            return
        })

        alertController.addAction(UIAlertAction(title: "Go back", style: .Default) { _ in
            dispatch_async(dispatch_get_main_queue(), {
                self.popViewControllerAnimated(true)
            })
        })

        presentViewController(alertController, animated: true, completion: nil)

        return false
    }
}

Now in any controller, just conform to RequestsNavigationPopVerification and this behaviour is adopted by default.

ArrayAdapter<String> should work.

i.e.:

Spinner spinner = new Spinner(this);
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>
            (this, android.R.layout.simple_spinner_item,
           spinnerArray); //selected item will look like a spinner set from XML
spinnerArrayAdapter.setDropDownViewResource(android.R.layout
                                                     .simple_spinner_dropdown_item);
spinner.setAdapter(spinnerArrayAdapter); 

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

SELECT owner, directory_name, directory_path
  FROM all_directories

You could just use an even simpler typedef:

typedef char *string;

Then, your malloc would look like a usual malloc:

string s = malloc(maxStringLength);

FXCop typically prefers OrdinalIgnoreCase. But your requirements may vary.

For English there is very little difference. It is when you wander into languages that have different written language constructs that this becomes an issue. I am not experienced enough to give you more than that.

OrdinalIgnoreCase

The StringComparer returned by the OrdinalIgnoreCase property treats the characters in the strings to compare as if they were converted to uppercase using the conventions of the invariant culture, and then performs a simple byte comparison that is independent of language. This is most appropriate when comparing strings that are generated programmatically or when comparing case-insensitive resources such as paths and filenames. http://msdn.microsoft.com/en-us/library/system.stringcomparer.ordinalignorecase.aspx

InvariantCultureIgnoreCase

The StringComparer returned by the InvariantCultureIgnoreCase property compares strings in a linguistically relevant manner that ignores case, but it is not suitable for display in any particular culture. Its major application is to order strings in a way that will be identical across cultures. http://msdn.microsoft.com/en-us/library/system.stringcomparer.invariantcultureignorecase.aspx

The invariant culture is the CultureInfo object returned by the InvariantCulture property.

The InvariantCultureIgnoreCase property actually returns an instance of an anonymous class derived from the StringComparer class.

To check if a Windows service named MySuperServiceVersion1 exists, even when you might not be sure of its exact name, you could employ a wildcard, using a substring like so:

 if (Get-Service -Name "*SuperService*" -ErrorAction SilentlyContinue)
{
    # do something
}

Windows sometimes is "broken by design", so you need to create an empty folder, and then mirror the "broken folder" with an "empty folder" with backup mode.

robocopy - cmd copy utility

/copyall - copies everything
/mir deletes item if there is no such item in source a.k.a mirrors source with
destination
/b works around premissions shenanigans

Create en empty dir like this:

mkdir empty

overwrite broken folder with empty like this:

robocopy /copyall /mir /b empty broken

and then delete that folder

rd broken /s
rd empty /s

If this does not help, try restarting in "recovery mode with command prompt" by holding shift when clicking restart and trying to run these command again in recovery mode

The standard function atoi() will likely do what you want.

A simple example using "atoi":

#include <unistd.h>

int main(int argc, char *argv[])
{
    int useconds = atoi(argv[1]); 
    usleep(useconds);
}

When generating CSR is possible to specify -ext attribute again to have it inserted in the CSR

keytool -certreq -file test.csr -keystore test.jks -alias testAlias -ext SAN=dns:test.example.com

complete example here: How to create CSR with SANs using keytool

I'd just drop the database and then re-create it. On a UNIX or Linux system, that should do it:

$ dropdb development_db_name
$ createdb developmnent_db_name

That's how I do it, actually.

Arrays in JavaScript don't use strings as keys. You will probably find that the value is there, but the key is an integer.

If you make Dict into an object, this will work:

var dict = {};
var addPair = function (myKey, myValue) {
    dict[myKey] = myValue;
};
var giveValue = function (myKey) {
    return dict[myKey];
};

The myKey variable is already a string, so you don't need more quotes.

Honestly, I had problems with bundler circular dependencies and the best way to go is rm -rf .bundle. Save yourselves the headache and just use the hammer.

I know this question is on Linux, but on windows I had the same issue. Turns out you have to start the command prompt in "Run As Administrator" mode for it to work. Otherwise you get the same: unable to write 'random state' error.

If you have a file object, this simple function will work:

function getBase64 (file, callback) {

    const reader = new FileReader();

    reader.addEventListener('load', () => callback(reader.result));

    reader.readAsDataURL(file);
}

Usage example:

getBase64(fileObjectFromInput, function(base64Data){
    console.log("Base64 of file is", base64Data); // Here you can have your code which uses Base64 for its operation, // file to Base64 by oneshubh
});

If you want to display the JSON data in well defined formate you can modify the code as:

file_put_contents($file, json_encode($json,TRUE));


$headers = array('http'=>array('method'=>'GET','header'=>'Content: type=application/json \r\n'.'$agent \r\n'.'$hash'));

$context=stream_context_create($headers);

$str = file_get_contents("list.txt",FILE_USE_INCLUDE_PATH,$context);

$str1=utf8_encode($str);

$str1=json_decode($str1,true);



foreach($str1 as $key=>$value)
{

    echo "key is: $key.\n";

    echo "values are: \t";
        foreach ($value as $k) {

        echo " $k. \t";
        # code...
    }
        echo "<br></br>";
        echo "\n";

}

Have a look at ?"%in%".

dt[dt$fct %in% vc,]
   fct X
1    a 2
3    c 3
5    c 5
7    a 7
9    c 9
10   a 1
12   c 2
14   c 4

You could also use ?is.element:

dt[is.element(dt$fct, vc),]

I created blog post on the topic. It contains also link to Github repository with working example.

The trick is using test configuration, where you override original spring bean with fake one. You can use @Primary and @Profile annotations for this trick.

Windows imposes a memory limit per process, you can see what it is for each version here

See:

User-mode virtual address space for each 64-bit process; With IMAGE_FILE_LARGE_ADDRESS_AWARE set (default): x64: 8 TB Intel IPF: 7 TB 2 GB with IMAGE_FILE_LARGE_ADDRESS_AWARE cleared

You need first to cut the string in how many pieces you want. Then replace the part that you want:

 $text = 'this is the test for string.';
 $text = substr($text, 0, 10);
 echo $text = str_replace(" ", "_", $text);

This will output:

this_is_th

First add an Enrty and Category class:

public class Entry {     public string Id { get; set; }     public string Title { get; set; }     public string Updated { get; set; }     public string Summary { get; set; }     public string GPoint { get; set; }     public string GElev { get; set; }     public List<string> Categories { get; set; } }  public class Category {     public string Label { get; set; }     public string Term { get; set; } } 

Then use LINQ to XML

XDocument xDoc = XDocument.Load("path");          List<Entry> entries = (from x in xDoc.Descendants("entry")             select new Entry()             {                 Id = (string) x.Element("id"),                 Title = (string)x.Element("title"),                 Updated = (string)x.Element("updated"),                 Summary = (string)x.Element("summary"),                 GPoint = (string)x.Element("georss:point"),                 GElev = (string)x.Element("georss:elev"),                 Categories = (from c in x.Elements("category")                                   select new Category                                   {                                       Label = (string)c.Attribute("label"),                                       Term = (string)c.Attribute("term")                                   }).ToList();             }).ToList(); 

Here is a method that works well and allows you to convert the file to a certain format as well (to avoid "cannot write mode P as JPEG" error):

import urllib2
from django.core.files.base import ContentFile
from PIL import Image
from StringIO import StringIO

def download_image(name, image, url):
    input_file = StringIO(urllib2.urlopen(url).read())
    output_file = StringIO()
    img = Image.open(input_file)
    if img.mode != "RGB":
        img = img.convert("RGB")
    img.save(output_file, "JPEG")
    image.save(name+".jpg", ContentFile(output_file.getvalue()), save=False)

where image is the django ImageField or your_model_instance.image here is a usage example:

p = ProfilePhoto(user=user)
download_image(str(user.id), p.image, image_url)
p.save()

Hope this helps

The simple way to do this is doing a div within a div

<div class="col-sm-4" style="padding: 5px;border:2px solid red;">_x000D_
   <div class="server-action-menu" id="server_1">Server 1_x000D_
   </div>_x000D_
 </div>_x000D_
<div class="col-sm-4" style="padding: 5px;border:2px solid red;">_x000D_
   <div class="server-action-menu" id="server_1">Server 2_x000D_
   </div>_x000D_
 </div>_x000D_
<div class="col-sm-4" style="padding: 5px;border:2px solid red;">_x000D_
   <div class="server-action-menu" id="server_1">Server 3_x000D_
   </div>_x000D_
 </div>

Give your submit buttons a name, and then inspect the submitted value in your controller method:

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<input type="submit" name="submitButton" value="Send" />
<input type="submit" name="submitButton" value="Cancel" />
<% Html.EndForm(); %>

posting to

public class MyController : Controller {
    public ActionResult MyAction(string submitButton) {
        switch(submitButton) {
            case "Send":
                // delegate sending to another controller action
                return(Send());
            case "Cancel":
                // call another action to perform the cancellation
                return(Cancel());
            default:
                // If they've submitted the form without a submitButton, 
                // just return the view again.
                return(View());
        }
    }

    private ActionResult Cancel() {
        // process the cancellation request here.
        return(View("Cancelled"));
    }

    private ActionResult Send() {
        // perform the actual send operation here.
        return(View("SendConfirmed"));
    }

}

EDIT:

To extend this approach to work with localized sites, isolate your messages somewhere else (e.g. compiling a resource file to a strongly-typed resource class)

Then modify the code so it works like:

<% Html.BeginForm("MyAction", "MyController", FormMethod.Post); %>
<input type="submit" name="submitButton" value="<%= Html.Encode(Resources.Messages.Send)%>" />
<input type="submit" name="submitButton" value="<%=Html.Encode(Resources.Messages.Cancel)%>" />
<% Html.EndForm(); %>

and your controller should look like this:

// Note that the localized resources aren't constants, so 
// we can't use a switch statement.

if (submitButton == Resources.Messages.Send) { 
    // delegate sending to another controller action
    return(Send());

} else if (submitButton == Resources.Messages.Cancel) {
     // call another action to perform the cancellation
     return(Cancel());
}

If the formula already exists in a cell you can fill it down as follows:

• Select the cell containing the formula and press CTRL+SHIFT+DOWN to select the rest of the column (CTRL+SHIFT+END to select up to the last row where there is data)
• Fill down by pressing CTRL+D
• Use CTRL+UP to return up

On Mac, use CMD instead of CTRL.

An alternative if the formula is in the first cell of a column:

• Select the entire column by clicking the column header or selecting any cell in the column and pressing CTRL+SPACE
• Fill down by pressing CTRL+D

Just use:

overflow: hidden;
white-space: nowrap;

In your item's divs

(months later) a tiny real example where lambda is useful, partial not:
say you want various 1-dimensional cross-sections through a 2-dimensional function, like slices through a row of hills.
quadf( x, f ) takes a 1-d f and calls it for various x.
To call it for vertical cuts at y = -1 0 1 and horizontal cuts at x = -1 0 1,

fx1 = quadf( x, lambda x: f( x, 1 ))
fx0 = quadf( x, lambda x: f( x, 0 ))
fx_1 = quadf( x, lambda x: f( x, -1 ))
fxy = parabola( y, fx_1, fx0, fx1 )

f_1y = quadf( y, lambda y: f( -1, y ))
f0y = quadf( y, lambda y: f( 0, y ))
f1y = quadf( y, lambda y: f( 1, y ))
fyx = parabola( x, f_1y, f0y, f1y )

As far as I know, partial can't do this --

quadf( y, partial( f, x=1 ))
TypeError: f() got multiple values for keyword argument 'x'

(How to add tags numpy, partial, lambda to this ?)

Making multiple versions of settings.py is an anti pattern for 12 Factor App methodology. use python-decouple or django-environ instead.

If you want to check whether the array contains items with null values, use this:

private boolean isListOfNulls(ArrayList<String> stringList){
    for (String s: stringList)
        if( s != null) return false;
    return true;
}

You could replace <String> with the corresponding type for your ArrayList

You cannot assign expressions with types such as List<NavigableMap<String,String>> to the first.

(If you want to know why you can't assign List<String> to List<Object> see a zillion other questions on SO.)

For those also using typescript on node-js and are getting a ReferenceError: fetch is not defined error

npm install these packages:

    "amazon-cognito-identity-js": "3.0.11"
    "node-fetch": "^2.3.0"

Then include:

import Global = NodeJS.Global;
export interface GlobalWithCognitoFix extends Global {
    fetch: any
}
declare const global: GlobalWithCognitoFix;
global.fetch = require('node-fetch');

One of the simplest way I found is to use pynput module.can be found here with nice examples as well

from pynput import keyboard

def on_press(key):
    try:
        print('alphanumeric key {0} pressed'.format(
            key.char))
    except AttributeError:
        print('special key {0} pressed'.format(
            key))

def on_release(key):
    print('{0} released'.format(
        key))
    if key == keyboard.Key.esc:
        # Stop listener
        return False

# Collect events until released
with keyboard.Listener(
        on_press=on_press,
        on_release=on_release) as listener:
    listener.join()

above is the example worked out for me and to install, go
for python 2:

    pip install pynput

for python 3:

    pip3 install pynput

According to the API Reference:

By default the height is calculated from the offset height of the containing element. Defaults to null.

So, you can control it's height according to the parent div using redraw event, which is called when it changes it's size.

Epydoc is a tool to generate API documentation from Python source code. It also generates UML class diagrams, using Graphviz in fancy ways. Here is an example of diagram generated from the source code of Epydoc itself.

Because Epydoc performs both object introspection and source parsing it can gather more informations respect to static code analysers such as Doxygen: it can inspect a fair amount of dynamically generated classes and functions, but can also use comments or unassigned strings as a documentation source, e.g. for variables and class public attributes.

The syntax to disable an HTML input is as follows:

<input type="text" id="input_id" DISABLED />

try with either of the 2 below commands

/usr/local/mysql/bin/mysql -uroot
-- OR --
/usr/local/Cellar/mysql/<version>/bin/mysql -uroot

It doesn't sound like a good idea to use send message. I think you should try to work around the problem that the DLLs can't reference each other...

I have a very simple solution for this problem. You don't need to use the console.

TLDR: Create repo, move files to existing projects folder, SourceTree will ask you where his files are, locate the files. Done, your repo is in another folder.

Long answer:

1. Create your new repository on Bitbucket
2. Click "Clone in SourceTree"
3. Let the program put your new repo where it wants, in my case SourceTree created a new folder in My Documents.
4. Locate in windows explorer your new repository folder.
5. Cut the .hg and README (or anything else you find in that folder)
6. Paste it in the location where is your existing project
7. Return to SourceTree and it will say "Error encountered...", just click OK
8. On the left side you will have your repository but with red message: Repository Moved or Deleted. Click on that.
9. Now you will see Repository Missing popup. Click on Change Folder and locate your existing project folder where you have moved the files mentoned earlier.
10. Thats it!

Tips: Clone in SourceTree option is not available right after you create new repository so you first have to click on Create Readme File for that option to become available.

I normally learn by example, and here's a little something:

const lives = 0;

function catCircus () {
    this.lives = 1;
    const lives = 2;

    const cat1 = {
        lives: 5,
        jumps: () => {
            console.log(this.lives);
        }
    };
    cat1.jumps(); // 1
    console.log(cat1); // { lives: 5, jumps: [Function: jumps] }

    const cat2 = {
        lives: 5,
        jumps: () => {
            console.log(lives);
        }
    };
    cat2.jumps(); // 2
    console.log(cat2); // { lives: 5, jumps: [Function: jumps] }

    const cat3 = {
        lives: 5,
        jumps: () => {
            const lives = 3;
            console.log(lives);
        }
    };
    cat3.jumps(); // 3
    console.log(cat3); // { lives: 5, jumps: [Function: jumps] }

    const cat4 = {
        lives: 5,
        jumps: function () {
            console.log(lives);
        }
    };
    cat4.jumps(); // 2
    console.log(cat4); // { lives: 5, jumps: [Function: jumps] }

    const cat5 = {
        lives: 5,
        jumps: function () {
            var lives = 4;
            console.log(lives);
        }
    };
    cat5.jumps(); // 4
    console.log(cat5); // { lives: 5, jumps: [Function: jumps] }

    const cat6 = {
        lives: 5,
        jumps: function () {
            console.log(this.lives);
        }
    };
    cat6.jumps(); // 5
    console.log(cat6); // { lives: 5, jumps: [Function: jumps] }

    const cat7 = {
        lives: 5,
        jumps: function thrownOutOfWindow () {
            console.log(this.lives);
        }
    };
    cat7.jumps(); // 5
    console.log(cat7); // { lives: 5, jumps: [Function: thrownOutOfWindow] }
}

catCircus();

You can always get your runtime path by using:

 String path = new File(".").getCanonicalPath();

This provides valuable information about where to put files and resources.

In python 3 you can use os.scandir():

for i in os.scandir(path):
    if i.is_file():
        print('File: ' + i.path)
    elif i.is_dir():
        print('Folder: ' + i.path)
