if ($inputs['type'] == 'attach') {

The code is valid, but it expects the function parameter $inputs to be an array. The "Illegal string offset" warning when using $inputs['type'] means that the function is being passed a string instead of an array. (And then since a string offset is a number, 'type' is not suitable.)

So in theory the problem lies elsewhere, with the caller of the code not providing a correct parameter.

However, this warning message is new to PHP 5.4. Old versions didn't warn if this happened. They would silently convert 'type' to 0, then try to get character 0 (the first character) of the string. So if this code was supposed to work, that's because abusing a string like this didn't cause any complaints on PHP 5.3 and below. (A lot of old PHP code has experienced this problem after upgrading.)

You might want to debug why the function is being given a string by examining the calling code, and find out what value it has by doing a var_dump($inputs); in the function. But if you just want to shut the warning up to make it behave like PHP 5.3, change the line to:

if (is_array($inputs) && $inputs['type'] == 'attach') {

In my case the following tsconfig.json solved problem:

{
  "compilerOptions": {
    "esModuleInterop": true,
    "target": "ES2020",
    "moduleResolution": "node"
  }
}

There should be no type: module in package.json.

On SmtpClient there is an EnableSsl property that you would set.

i.e.

SmtpClient client = new SmtpClient(exchangeServer);
client.EnableSsl = true;
client.Send(msg);

Is this what you need?

DataTable myDataTable = new DataTable();
List<int> myList = new List<int>();
foreach (DataRow row in myDataTable.Rows)
{
    myList.Add((int)row[0]);
}

As long as your selector is actually working, I see nothing wrong with your code that checks the length of the array. That should do what you want. There are a lot of ways to clean up your code to be simpler and more readable. Here's a cleaned up version with notes about what I cleaned up.

var album_text = [];

$("input[name='album_text[]']").each(function() {
    var value = $(this).val();
    if (value) {
        album_text.push(value);
    }
});
if (album_text.length === 0) {
    $('#error_message').html("Error");
}

else {
  //send data
}

Some notes on what you were doing and what I changed.

1. $(this) is always a valid jQuery object so there's no reason to ever check if ($(this)). It may not have any DOM objects inside it, but you can check that with $(this).length if you need to, but that is not necessary here because the .each() loop wouldn't run if there were no items so $(this) inside your .each() loop will always be something.
2. It's inefficient to use $(this) multiple times in the same function. Much better to get it once into a local variable and then use it from that local variable.
3. It's recommended to initialize arrays with [] rather than new Array().
4. if (value) when value is expected to be a string will both protect from value == null, value == undefined and value == "" so you don't have to do if (value && (value != "")). You can just do: if (value) to check for all three empty conditions.
5. if (album_text.length === 0) will tell you if the array is empty as long as it is a valid, initialized array (which it is here).

What are you trying to do with this selector $("input[name='album_text[]']")?

FULL is probably referring to a full table scan, which means that no indexes are in use. This is usually indicating that something is wrong, unless the query is supposed to use all the rows in a table.

Cost is a number that signals the sum of the different loads, processor, memory, disk, IO, and high numbers are typically bad. The numbers are added up when moving to the root of the plan, and each branch should be examined to locate the bottlenecks.

You may also want to query v$sql and v$session to get statistics about SQL statements, and this will have detailed metrics for all kind of resources, timings and executions.

Fun 'base_url' snippet!

if (!function_exists('base_url')) {
    function base_url($atRoot=FALSE, $atCore=FALSE, $parse=FALSE){
        if (isset($_SERVER['HTTP_HOST'])) {
            $http = isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) !== 'off' ? 'https' : 'http';
            $hostname = $_SERVER['HTTP_HOST'];
            $dir =  str_replace(basename($_SERVER['SCRIPT_NAME']), '', $_SERVER['SCRIPT_NAME']);

            $core = preg_split('@/@', str_replace($_SERVER['DOCUMENT_ROOT'], '', realpath(dirname(__FILE__))), NULL, PREG_SPLIT_NO_EMPTY);
            $core = $core[0];

            $tmplt = $atRoot ? ($atCore ? "%s://%s/%s/" : "%s://%s/") : ($atCore ? "%s://%s/%s/" : "%s://%s%s");
            $end = $atRoot ? ($atCore ? $core : $hostname) : ($atCore ? $core : $dir);
            $base_url = sprintf( $tmplt, $http, $hostname, $end );
        }
        else $base_url = 'http://localhost/';

        if ($parse) {
            $base_url = parse_url($base_url);
            if (isset($base_url['path'])) if ($base_url['path'] == '/') $base_url['path'] = '';
        }

        return $base_url;
    }
}

Use as simple as:

//  url like: http://stackoverflow.com/questions/2820723/how-to-get-base-url-with-php

echo base_url();    //  will produce something like: http://stackoverflow.com/questions/2820723/
echo base_url(TRUE);    //  will produce something like: http://stackoverflow.com/
echo base_url(TRUE, TRUE); || echo base_url(NULL, TRUE);    //  will produce something like: http://stackoverflow.com/questions/
//  and finally
echo base_url(NULL, NULL, TRUE);
//  will produce something like: 
//      array(3) {
//          ["scheme"]=>
//          string(4) "http"
//          ["host"]=>
//          string(12) "stackoverflow.com"
//          ["path"]=>
//          string(35) "/questions/2820723/"
//      }

If you are using Entity Framework 5 < you can use DbGeography. Example from MSDN:

public class University  
{ 
    public int UniversityID { get; set; } 
    public string Name { get; set; } 
    public DbGeography Location { get; set; } 
}

public partial class UniversityContext : DbContext 
{ 
    public DbSet<University> Universities { get; set; } 
}

using (var context = new UniversityContext ()) 
{ 
    context.Universities.Add(new University() 
        { 
            Name = "Graphic Design Institute", 
            Location = DbGeography.FromText("POINT(-122.336106 47.605049)"), 
        }); 

    context. Universities.Add(new University() 
        { 
            Name = "School of Fine Art", 
            Location = DbGeography.FromText("POINT(-122.335197 47.646711)"), 
        }); 

    context.SaveChanges(); 

    var myLocation = DbGeography.FromText("POINT(-122.296623 47.640405)"); 

    var university = (from u in context.Universities 
                        orderby u.Location.Distance(myLocation) 
                        select u).FirstOrDefault(); 

    Console.WriteLine( 
        "The closest University to you is: {0}.", 
        university.Name); 
}

https://msdn.microsoft.com/en-us/library/hh859721(v=vs.113).aspx

Something I struggled with then I started using DbGeography was the coordinateSystemId. See the answer below for an excellent explanation and source for the code below.

public class GeoHelper
{
    public const int SridGoogleMaps = 4326;
    public const int SridCustomMap = 3857;

    public static DbGeography FromLatLng(double lat, double lng)
    {
        return DbGeography.PointFromText(
            "POINT("
            + lng.ToString() + " "
            + lat.ToString() + ")",
            SridGoogleMaps);
    }
}

For others who landed in this error and it's not 100% related to the OP question, please check that you are passing the value and it is not null in case of spring-boot: @Value annotation.

Set the tagName as an explicit attribute:

for(var i=0,els=document.querySelectorAll('*'); i<els.length;
          els[i].setAttribute('tagName',els[i++].tagName) );

I needed this myself, for an XML Document, with Nested Tags ending in _Sequence. See JaredMcAteer answer for more details.

document.querySelectorAll('[tagName$="_Sequence"]')

I didn't say it would be pretty :) PS: I would recommend to use tag_name over tagName, so you do not run into interferences when reading 'computer generated', implicit DOM attributes.

Creating an AsyncResult object from the task id is the way recommended in the FAQ to obtain the task status when the only thing you have is the task id.

However, as of Celery 3.x, there are significant caveats that could bite people if they do not pay attention to them. It really depends on the specific use-case scenario.

By default, Celery does not record a "running" state.

In order for Celery to record that a task is running, you must set task_track_started to True. Here is a simple task that tests this:

@app.task(bind=True)
def test(self):
    print self.AsyncResult(self.request.id).state

When task_track_started is False, which is the default, the state show is PENDING even though the task has started. If you set task_track_started to True, then the state will be STARTED.

The state PENDING means "I don't know."

An AsyncResult with the state PENDING does not mean anything more than that Celery does not know the status of the task. This could be because of any number of reasons.

For one thing, AsyncResult can be constructed with invalid task ids. Such "tasks" will be deemed pending by Celery:

>>> task.AsyncResult("invalid").status
'PENDING'

Ok, so nobody is going to feed obviously invalid ids to AsyncResult. Fair enough, but it also has for effect that AsyncResult will also consider a task that has successfully run but that Celery has forgotten as being PENDING. Again, in some use-case scenarios this can be a problem. Part of the issue hinges on how Celery is configured to keep the results of tasks, because it depends on the availability of the "tombstones" in the results backend. ("Tombstones" is the term use in the Celery documentation for the data chunks that record how the task ended.) Using AsyncResult won't work at all if task_ignore_result is True. A more vexing problem is that Celery expires the tombstones by default. The result_expires setting by default is set to 24 hours. So if you launch a task, and record the id in long-term storage, and more 24 hours later, you create an AsyncResult with it, the status will be PENDING.

All "real tasks" start in the PENDING state. So getting PENDING on a task could mean that the task was requested but never progressed further than this (for whatever reason). Or it could mean the task ran but Celery forgot its state.

Ouch! AsyncResult won't work for me. What else can I do?

I prefer to keep track of goals than keep track of the tasks themselves. I do keep some task information but it is really secondary to keeping track of the goals. The goals are stored in storage independent from Celery. When a request needs to perform a computation depends on some goal having been achieved, it checks whether the goal has already been achieved, if yes, then it uses this cached goal, otherwise it starts the task that will effect the goal, and sends to the client that made the HTTP request a response that indicates it should wait for a result.

The variable names and hyperlinks above are for Celery 4.x. In 3.x the corresponding variables and hyperlinks are: CELERY_TRACK_STARTED, CELERY_IGNORE_RESULT, CELERY_TASK_RESULT_EXPIRES.

Try using Replace to see if it will work for you. The problem as I see it which has been mentioned a few times above is the CDate function is choking on the periods. You can use replace to change them to slashes. To answer your question about a Function in vba that can parse any date format, there is not any you have very limited options.

Dim current as Date, highest as Date, result() as Date 
For Each itemDate in DeliveryDateArray
    Dim tempDate As String
    itemDate = IIf(Trim(itemDate) = "", "0", itemDate) 'Added per OP's request.
    tempDate = Replace(itemDate, ".", "/")
    current = Format(CDate(tempDate),"dd/mm/yyyy")
    if current > highest then 
        highest = current 
    end if 
    ' some more operations an put dates into result array 
Next itemDate 
'After activating final sheet... 
Range("A1").Resize(UBound(result), 1).Value = Application.Transpose(result) 

Listen to the podcast JavaScript Jabber: Episode #32 that features the original creators of AngularJS: Misko Hevery & Igor Minar. They talk a lot about what it's like to come to AngularJS from other JavaScript backgrounds, especially jQuery.

One of the points made in the podcast made a lot of things click for me with respects to your question:

MISKO: [...] one of the things we thought about very hardly in Angular is, how do we provide lots of escape hatches so that you can get out and basically figure out a way out of this. So to us, the answer is this thing called “Directives”. And with directives, you essentially become a regular little jQuery JavaScript, you can do whatever you want.

IGOR: So think of directive as the instruction to the compiler that tells it whenever you come across this certain element or this CSS in the template, and you keep this kind of code and that code is in charge of the element and everything below that element in the DOM tree.

A transcript of the entire episode is available at the link provided above.

So, to directly answer your question: AngularJS is -very- opinionated and is a true MV* framework. However, you can still do all of the really cool stuff you know and love with jQuery inside of directives. It's not a matter of "How do I do what I used to in jQuery?" as much as it's a matter of "How do I supplement AngularJS with all of the stuff I used to do in jQuery?"

It's really two very different states of mind.

If one or both of the files you wish to compare isn't in an Eclipse project:

1. Open the Quick Access search box

   • Linux/Windows: Ctrl+3
   • Mac: ?+3

2. Type compare and select Compare With Other Resource

3. Select the files to compare ? OK

You can also create a keyboard shortcut for Compare With Other Resource by going to Window ? Preferences ? General ? Keys

It's safer to always percent-encode all characters except those defined as "unreserved" in RFC-3986.

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

So, percent-encode the plus character and other special characters.

The problem that you are having with pluses is because, according to RFC-1866 (HTML 2.0 specification), paragraph 8.2.1. subparagraph 1., "The form field names and values are escaped: space characters are replaced by `+', and then reserved characters are escaped"). This way of encoding form data is also given in later HTML specifications, look for relevant paragraphs about application/x-www-form-urlencoded.

I was have same problem and i found solution by adding path to file like:

@import "C:/xampp/htdocs/Scss_addons/Bootstrap/bootstrap";

@import "C:/xampp/htdocs/Scss_addons/Compass/compass";

Simplest way I've found:

in your activity XML add these lines:

<ListView 
... 
android:choiceMode="singleChoice"
android:listSelector="#666666"
/>

or programatically set these properties:

listView.setSelector(Drawable selector)
listView.setSelector(int resourceId)

My particular example:

   <ListView
            android:choiceMode="singleChoice"
            android:listSelector="#666666"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/listView"/>

You will need to melt your dataframe to get it into the so-called long format:

require(reshape2)
sample.data.M <- melt(sample.data)

Now your field values are represented by their own rows and identified through the variable column. This can now be leveraged within the ggplot aesthetics:

require(ggplot2)
c <- ggplot(sample.data.M, aes(x = Rank, y = value, fill = variable))
c + geom_bar(stat = "identity")

Instead of stacking you may also be interested in showing multiple plots using facets:

c <- ggplot(sample.data.M, aes(x = Rank, y = value))
c + facet_wrap(~ variable) + geom_bar(stat = "identity")

You could also use the Executors object to create an ExecutorService thread pool. Then use the invokeAll method to run each of your threads and retrieve Futures. This will block until all have finished execution. Your other option would be to execute each one using the pool and then call awaitTermination to block until the pool is finished executing. Just be sure to call shutdown() when you're done adding tasks.

I tried most of the answers and unfortunately, none of them worked in completion.

Here is what worked for me. There are 3 things to do to the site you want PUT for (select the site) :

1. Open WebDav Authoring Rules and then select Disable WebDAV option present on the right bar.

2. Select Modules, find the WebDAV Module and remove it.

3. Select HandlerMapping, find the WebDAVHandler and remove it.

Restart IIS.

In my case (I am using Xamarin Forms) this error was thrown due to a binding error - e.g. :

<Label Grid.Column="4" Grid.Row="1" VerticalTextAlignment="Start" HorizontalTextAlignment="Center"  VerticalOptions="Start" HorizontalOptions="Start" FontSize="10" TextColor="Pink" Text="{Binding }"></Label>

Basically I deleted the view model property by mistake. For Xamarin developers, if you have the same issue, check your bindings...

BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize=2; //try to decrease decoded image 
Bitmap bitmap=BitmapFactory.decodeStream(is, null, options); 
bitmap.compress(Bitmap.CompressFormat.JPEG, 70, fos); //compressed bitmap to file 

If you want an actual boolean column:

ALTER TABLE users ADD "priv_user" boolean DEFAULT false;

The accepted answer works great, but the resize logic ignores the case in which the image is larger than the maximum in only one of the axes (for example, height > maxHeight but width <= maxWidth).

I think the following code takes care of all cases in a more straight-forward and functional way (ignore the typescript type annotations if using plain javascript):

private scaleDownSize(width: number, height: number, maxWidth: number, maxHeight: number): {width: number, height: number} {
    if (width <= maxWidth && height <= maxHeight)
      return { width, height };
    else if (width / maxWidth > height / maxHeight)
      return { width: maxWidth, height: height * maxWidth / width};
    else
      return { width: width * maxHeight / height, height: maxHeight };
  }

You can use the following method:

select
STUFF(
        (
        select ', ' + CONVERT(varchar(10), ID) FROM @temp
        where ID<50
group by ID for xml path('')
        ), 1, 2, '') as IDs

Implementation:

Declare @temp Table(
ID int
)
insert into @temp
(ID)
values
(1)
insert into @temp
(ID)
values
(3)
insert into @temp
(ID)
values
(5)
insert into @temp
(ID)
values
(9)

 select
STUFF(
        (
        select ', ' + CONVERT(varchar(10), ID) FROM @temp
        where ID<50
group by ID for xml path('')
        ), 1, 2, '') as IDs

Result will be:

I'd say the code you need is:

test = input("enter the test")
print(test)

Otherwise it shouldn't run at all, due to a syntax error. The print function requires brackets in python 3. I cannot reproduce your error, though. Are you sure it's those lines causing that error?

Could it be that your file is not ISO-8859-15 encoded? You should be able to check with the file command:

file YourFile.txt

Also, you can use iconv without providing the encoding of the original file:

iconv -t UTF-8 YourFile.txt

Only call time pass-by-reference is removed. So change:

call_user_func($func, &$this, &$client ...

To this:

call_user_func($func, $this, $client ...

&$this should never be needed after PHP4 anyway period.

If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {)

Based on this answer

<input type="text" id="sno" placeholder="Only float with dot !"   
   onkeypress="return (event.charCode >= 48 && event.charCode <= 57) ||  
   event.charCode == 46 || event.charCode == 0 ">

Meaning :

Char code :

• 48-57 equal to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
• 0 is Backspace(otherwise need refresh page on Firefox)
• 46 is dot

&& is AND , || is OR operator.

if you try float with comma :

<input type="text" id="sno" placeholder="Only float with comma !"   
     onkeypress="return (event.charCode >= 48 && event.charCode <= 57) ||  
     event.charCode == 44 || event.charCode == 0 ">

Supported Chromium and Firefox (Linux X64)(other browsers I does not exist.)

Following the documentation of fopen:

``a'' Open for writing. The file is created if it does not exist. The stream is positioned at the end of the file. Subsequent writes to the file will always end up at the then cur- rent end of file, irrespective of any intervening fseek(3) or similar.

So if you pFile2=fopen("myfile2.txt", "a"); the stream is positioned at the end to append automatically. just do:

FILE *pFile;
FILE *pFile2;
char buffer[256];

pFile=fopen("myfile.txt", "r");
pFile2=fopen("myfile2.txt", "a");
if(pFile==NULL) {
    perror("Error opening file.");
}
else {
    while(fgets(buffer, sizeof(buffer), pFile)) {
        fprintf(pFile2, "%s", buffer);
    }
}
fclose(pFile);
fclose(pFile2);

console.log("my object: %o", myObj)

Otherwise you'll end up with a string representation sometimes displaying:

[object Object]

or some such.

You can use VARRAY for a fixed-size array:

declare
   type array_t is varray(3) of varchar2(10);
   array array_t := array_t('Matt', 'Joanne', 'Robert');
begin
   for i in 1..array.count loop
       dbms_output.put_line(array(i));
   end loop;
end;

Or TABLE for an unbounded array:

...
   type array_t is table of varchar2(10);
...

The word "table" here has nothing to do with database tables, confusingly. Both methods create in-memory arrays.

With either of these you need to both initialise and extend the collection before adding elements:

declare
   type array_t is varray(3) of varchar2(10);
   array array_t := array_t(); -- Initialise it
begin
   for i in 1..3 loop
      array.extend(); -- Extend it
      array(i) := 'x';
   end loop;
end;

The first index is 1 not 0.

An ugly solution but it works:

function Class(cb) {
    const self = {};

    const constructor = (fn) => {
        func = fn;    
    };

    const addPrivate = (fnName, obj) => {
        self[fnName] = obj;
    }

    const addPublic = (fnName, obj) => {
        this[fnName] = obj;
        self[fnName] = obj;
        func.prototype[fnName] = obj;
    }
    
    cb(constructor, addPrivate, addPublic, self);
    return func;
}

const test = new Class((constructor, private, public, self) => {
    constructor(function (test) {
        console.log(test)
    });
    public('test', 'yay');
    private('qwe', 'nay');
    private('no', () => {
        return 'hello'
    })
    public('asd', () => {
        return 'this is public'
    })
    public('hello', () => {
        return self.qwe + self.no() + self.asd()
    })
})
const asd = new test('qweqwe');
console.log(asd.hello());

This query will help you:

select * 
from XXXX
where datepart(YYYY,create_date)>=2013 
and DATEPART(YYYY,create_date)<=2014

If you're certain that only Javascript will be consuming the JSON, I prefer to pass Javascript Date objects directly.

The ctime() method on datetime objects will return a string that the Javascript Date object can understand.

import datetime
date = datetime.datetime.today()
json = '{"mydate":new Date("%s")}' % date.ctime()

Javascript will happily use that as an object literal, and you've got your Date object built right in.

A slight extension to the answer given, so, hopefully useful to the asker and anyone else looking.

You can also SELECT the values you want to delete. But watch out for the Error 1093 - You can't specify the target table for update in FROM clause.

DELETE FROM
    orders_products_history
WHERE
    (branchID, action) IN (
    SELECT
        branchID,
        action
    FROM
        (
        SELECT
            branchID,
            action
        FROM
            orders_products_history
        GROUP BY
            branchID,
            action
        HAVING
            COUNT(*) > 10000
        ) a
    );

I wanted to delete all history records where the number of history records for a single action/branch exceed 10,000. And thanks to this question and chosen answer, I can.

Hope this is of use.

In some languages, you can use an alternative library, For example, tampax is an implementation of YAML handling variables:

const tampax = require('tampax');

const yamlString = `
dude:
  name: Arthur
weapon:
  favorite: Excalibur
  useless: knife
sentence: "{{dude.name}} use {{weapon.favorite}}. The goal is {{goal}}."`;

const r = tampax.yamlParseString(yamlString, { goal: 'to kill Mordred' });
console.log(r.sentence);

// output : "Arthur use Excalibur. The goal is to kill Mordred."

Editor's Note: poster is also the author of this package.

Here I'm just doing the difference between today, and a CREATED_DATE DATE field in a table, which obviously is a date in the past:

SELECT  
((FLOOR(ABS(MONTHS_BETWEEN(CREATED_DATE, SYSDATE))) / 12) * 12) || ' months, '  AS MONTHS,
-- we take total days - years(as days) - months(as days) to get remaining days
FLOOR((SYSDATE - CREATED_DATE) -      -- total days
(FLOOR((SYSDATE - CREATED_DATE)/365)*12)*(365/12) -      -- years, as days
-- this is total months - years (as months), to get number of months, 
-- then multiplied by 30.416667 to get months as days (and remove it from total days)
FLOOR(((SYSDATE - CREATED_DATE)/365)*12 - (FLOOR((SYSDATE - CREATED_DATE)/365)*12)) * (365/12))
|| ' days ' AS DAYS 
FROM MyTable

I use (365/12), or 30.416667, as my conversion factor because I'm using total days and removing years and months (as days) to get the remainder number of days. It was good enough for my purposes, anyway.

You can grep the logs to see the version. Let's say kafka is installed under /usr/local/kafka, then:

$ grep "Kafka version" /usr/local/kafka/logs/*

/usr/local/kafka/logs/kafkaServer.out: INFO Kafka version : 0.9.0.1 (org.apache.kafka.common.utils.AppInfoParser)

will reveal the version

Here is the easiest way of creating a splash screen:

First of all, add the following line of code before the namespace in Form1.cs code:

using System.Threading;

Now, follow the following steps:

1. Add a new form in you application

2. Name this new form as FormSplashScreen

3. In the BackgroundImage property, choose an image from one of your folders

4. Add a progressBar

5. In the Dock property, set it as Bottom

6. In MarksAnimationSpeed property, set as 50

7. In your main form, named as Form1.cs by default, create the following method:

    private void StartSplashScreen()
    {
        Application.Run(new Forms.FormSplashScreen());
    }
   

8. In the constructor method of Form1.cs, add the following code:

    public Form1()
    {
        Thread t = new Thread(new ThreadStart(StartSplashScreen));
        t.Start();
        Thread.Sleep(5000);
   
        InitializeComponent();//This code is automatically generated by Visual Studio
   
        t.Abort();
    }
   

9. Now, just run the application, it is going to work perfectly.

As solution could be also considering encoding to a format which doesn't contain symbol., as base64.

In js should be added

btoa(parameter); 

In controller

byte[] bytes = Convert.FromBase64String(parameter);
string parameter= Encoding.UTF8.GetString(bytes);

location / { is the most general location (with location {). It will match anything, AFAIU. I doubt that it would be useful to have location / { index index.html; } because of a lot of duplicate content for every subdirectory of your site.

The approach with

try_files $uri $uri/index.html index.html;

is bad, as mentioned in a comment above, because it returns index.html for pages which should not exist on your site (any possible $uri will end up in that). Also, as mentioned in an answer above, there is an internal redirect in the last argument of try_files.

Your approach

location = / {
   index index.html;

is also bad, since index makes an internal redirect too. In case you want that, you should be able to handle that in a specific location. Create e.g.

location = /index.html {

as was proposed here. But then you will have a working link http://example.org/index.html, which may be not desired. Another variant, which I use, is:

root /www/my-root;

# http://example.org
# = means exact location
location = / {
    try_files /index.html =404;
}

# disable http://example.org/index as a duplicate content
location = /index      { return 404; }

# This is a general location. 
# (e.g. http://example.org/contacts <- contacts.html)
location / {
    # use fastcgi or whatever you need here
    # return 404 if doesn't exist
    try_files $uri.html =404;
}

P.S. It's extremely easy to debug nginx (if your binary allows that). Just add into the server { block:

error_log /var/log/nginx/debug.log debug;

and see there all internal redirects etc.

Basically copying and pasting from Bjarne Stroustrup's "The C++ Programming Language 4th Edition":

List initialization does not allow narrowing (§iso.8.5.4). That is:

• An integer cannot be converted to another integer that cannot hold its value. For example, char to int is allowed, but not int to char.
• A floating-point value cannot be converted to another floating-point type that cannot hold its value. For example, float to double is allowed, but not double to float.
• A floating-point value cannot be converted to an integer type.
• An integer value cannot be converted to a floating-point type.

Example:

void fun(double val, int val2) {

    int x2 = val;    // if val == 7.9, x2 becomes 7 (bad)

    char c2 = val2;  // if val2 == 1025, c2 becomes 1 (bad)

    int x3 {val};    // error: possible truncation (good)

    char c3 {val2};  // error: possible narrowing (good)

    char c4 {24};    // OK: 24 can be represented exactly as a char (good)

    char c5 {264};   // error (assuming 8-bit chars): 264 cannot be 
                     // represented as a char (good)

    int x4 {2.0};    // error: no double to int value conversion (good)

}

The only situation where = is preferred over {} is when using auto keyword to get the type determined by the initializer.

Example:

auto z1 {99};   // z1 is an int
auto z2 = {99}; // z2 is std::initializer_list<int>
auto z3 = 99;   // z3 is an int

Conclusion

Prefer {} initialization over alternatives unless you have a strong reason not to.

for Angular 6+ and >=RC.6

.html

<form [formGroup]="formGroup">
  <input type="text" formControlName="myName">
</form>

.ts

public formGroup: FormGroup;
this.formGroup.value.myName

should also work.

Note that if the object you are talking about has a custom property model (such as DataRowView etc for DataTable), then you need to use TypeDescriptor; the good news is that this still works fine for regular classes (and can even be much quicker than reflection):

foreach(PropertyDescriptor prop in TypeDescriptor.GetProperties(obj)) {
    Console.WriteLine("{0} = {1}", prop.Name, prop.GetValue(obj));
}

This also provides easy access to things like TypeConverter for formatting:

    string fmt = prop.Converter.ConvertToString(prop.GetValue(obj));

You need to modify the Starter-Application class as shown below.

@SpringBootApplication

@EnableAutoConfiguration

@ComponentScan(basePackages="com.nice.application")

@EnableJpaRepositories("com.spring.app.repository")

public class InventoryApp extends SpringBootServletInitializer {..........

And update the Controller, Service and Repository packages structure as I mentioned below.

Example: REST-Controller

package com.nice.controller; --> It has to be modified as
package com.nice.application.controller;

You need to follow proper package structure for all packages which are in Spring Boot MVC flow.

So, If you modify your project bundle package structures correctly then your spring boot app will work correctly.

I made it work by upgrading the WebApi package to the prerelease version using nuget:

PM> Microsoft.AspNet.WebApi -Pre

In order to force the project using the latest version of WebApi, some modifications to the root Web.config were necessary:

1) Webpages Version from 2.0.0.0 to 3.0.0.0

<appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
</appSettings>

2) Binding redirect to 5.0.0.0 for System.Web.Http and System.Net.Http.Formatting

<dependentAssembly>
    <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>
<dependentAssembly>
    <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>

I think that's it

PS: Solution highly inspired from WebAPI OData 5.0 Beta - Accessing GlobalConfiguration throws Security Error

from string import rstrip

with open('bvc.txt') as f:
    alist = map(rstrip, f)

Nota Bene: rstrip() removes the whitespaces, that is to say : \f , \n , \r , \t , \v , \x and blank ,
but I suppose you're only interested to keep the significant characters in the lines. Then, mere map(strip, f) will fit better, removing the heading whitespaces too.

If you really want to eliminate only the NL \n and RF \r symbols, do:

with open('bvc.txt') as f:
    alist = f.read().splitlines()

splitlines() without argument passed doesn't keep the NL and RF symbols (Windows records the files with NLRF at the end of lines, at least on my machine) but keeps the other whitespaces, notably the blanks and tabs.

.

with open('bvc.txt') as f:
    alist = f.read().splitlines(True)

has the same effect as

with open('bvc.txt') as f:
    alist = f.readlines()

that is to say the NL and RF are kept

Based on @blushrt 's great answer I will update this response. Just using -

$("#Select_ID").val(id);

works if you've preloaded everything you need to the selector.

With no additional plugin required, this bootstrap solution works great for me:

<div style="position:relative;">
        <a class='btn btn-primary' href='javascript:;'>
            Choose File...
            <input type="file" style='position:absolute;z-index:2;top:0;left:0;filter: alpha(opacity=0);-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";opacity:0;background-color:transparent;color:transparent;' name="file_source" size="40"  onchange='$("#upload-file-info").html($(this).val());'>
        </a>
        &nbsp;
        <span class='label label-info' id="upload-file-info"></span>
</div>

you can also get this if you are trying to hit the same URL with multiple HTTP request at the same time.Many curl requests wont be able to connect and so return with error

If you're doing it in VBA (and not in a query) then: where field like "AA" and field not like "BB" then would not work.

You'd have to use: where field like "AA" and field like "BB" = false then

Laravel 5.4 You can use

 php artisan make:model --migration --controller --resource Test

This will create 1) Model 2) controller with default resource function 3) Migration file

And Got Answer

Model created successfully.

Controller created successfully.

after research i found solution with short code. first of all create a public instance on fragment and just remove your fragment on onSaveInstanceState if fragment not recreating on orientation change.

 @Override
public void onSaveInstanceState(Bundle outState) {
    if (null != mCalFragment) {
        FragmentTransaction bt = getChildFragmentManager().beginTransaction();
        bt.remove(mFragment);
        bt.commit();
    }
    super.onSaveInstanceState(outState);
}

I've just noticed something while researching this after getting help with https.request for post method. Thought I share some input to help understand.

process.stdout.write doesn't add a new line while console.log does, like others had mentioned. But there's also this which is easier to explain with examples.

var req = https.request(options, (res) => {
    res.on('data', (d) => {
        process.stdout.write(d);
        console.log(d)
    });
});

process.stdout.write(d); will print the data properly without a new line. However console.log(d) will print a new line but the data won't show correctly, giving this <Buffer 12 34 56... for example.

To make console.log(d) show the information correctly, I would have to do this.

var req = https.request(options, (res) => {
    var dataQueue = "";    
    res.on("data", function (d) {
        dataQueue += d;
    });
    res.on("end", function () {
        console.log(dataQueue);
    });
});

So basically:

• process.stdout.write continuously prints the information as the data being retrieved and doesn't add a new line.

• console.log prints the information what was obtained at the point of retrieval and adds a new line.

That's the best way I can explain it.

It's mainly a matter of choice most of the time. It's a matter of preference.

Note however that if you have numeric keys for example, that you can't do:

mydict = dict(1="foo", 2="bar")

You have to do:

mydict = {"1":"foo", "2":"bar"}

For any OS X users and future me, you also need to set GOBIN to avoid this confusing message on install and go get

mkdir bin 
export GOBIN=$GOPATH/bin

I tried a lot of plugins, most of them don't support all browsers, I prefer iScroll and nanoScroller works for all these browsers :

• IE11 -> IE6
• IE10 - WP8
• IE9 - WP7
• IE Xbox One
• IE Xbox 360
• Google Chrome
• FireFox
• Opera
• Safari

But iScroll do not work with touch!

I tried experimenting with the answers given. My personal finding came out to be:

git rm -r --cached .

And then

git add .

This seemed to make my working directory nice and clean. You can put your fileName in place of the dot.

Here is the code little modified that i got it from google -

 List data_table = new ArrayList<>();
    Class.forName("oracle.jdbc.driver.OracleDriver");
            con = DriverManager.getConnection(conn_url, user_id, password);

            System.out.println("query_string: "+query_string);
            ResultSet rs = stmt.executeQuery(query_string);
            ResultSetMetaData rsmd = rs.getMetaData();


            int row_count = 0;
            while (rs.next()) {
                HashMap<String, String> data_map = new HashMap<>();
                if (row_count == 240001) {
                    break;
                }
                for (int i = 1; i <= rsmd.getColumnCount(); i++) {
                    data_map.put(rsmd.getColumnName(i), rs.getString(i));
                }
                data_table.add(data_map);
                row_count = row_count + 1;
            }
            rs.close();
            stmt.close();
            con.close();

As of Chrome 52, the UI has changed. When the Developer Tools dialog is open, you select the vertical ellipsis and can then choose the docking position:

Select the icon on the left to open the Chrome Developer Tools in a new window:

Previously

Click and hold the button next to the close button of the Developer Tool in order to reveal the "Undock into separate window" option.

Note: A "press" is not enough in that state.

My pattern is complicated, but it covers exactly "Any positive integer, excluding 0" (1 - 2147483647, not long). It's for decimal numbers and doesn't allow leading zeros.

I'm not sure what you're trying to do, but here's something to consider: c(); won't do anything. c is an instance of the class checkbox and not a method to be called. So consider this:

public class FirstWindow extends JFrame {      public FirstWindow() {         checkbox c = new checkbox();         c.yourMethod(yourParameters); // call the method you made in checkbox     } }  public class checkbox extends JFrame {      public checkbox(yourParameters) {          // this is the constructor method used to initialize instance variables     }      public void yourMethod() // doesn't have to be void     {         // put your code here     } }

This works best in Firefox. Too bad that Chrome and Safari do not support this rather easy CSS styling.

Dictionary data type has a method called dict_name.pop(item) and this can be used to delete a key:value pair from a dictionary.

a={9:4,2:3,4:2,1:3}
a.pop(9)
print(a)

This will give the output as:

{2: 3, 4: 2, 1: 3}

This way you can delete an item from a dictionary in one line.

Ctrl+0 or empty the value and hit enter.

You should try removing the following code from your fragments

    try {
        mListener = (OnFragmentInteractionListener) activity;
    } catch (ClassCastException e) {
        throw new ClassCastException(activity.toString()
                + " must implement OnFragmentInteractionListener");
    }

The interface/listener is a default created so that your activity and fragments can communicate easier

You can manage the builder cache with docker builder

To clean all the cache with no prompt: docker builder prune -af

Even you can do like this

display:block;
overflow:auto;
height: 100%;

This will include your each dynamic div as per the content. Suppose if you have a common div with class it will increase height of each dynamic div according to the content

C version of @Nayfe code, generating SHA1 hash from file:

#include <stdio.h>
#include <openssl/sha.h>

static const int K_READ_BUF_SIZE = { 1024 * 16 };
unsigned char* calculateSHA1(char *filename)
{
    if (!filename) {
        return NULL;
    }

    FILE *fp = fopen(filename, "rb");
    if (fp == NULL) {
        return NULL;
    }

    unsigned char* sha1_digest = malloc(sizeof(char)*SHA_DIGEST_LENGTH);
    SHA_CTX context;

    if(!SHA1_Init(&context))
        return NULL;

    unsigned char buf[K_READ_BUF_SIZE];
    while (!feof(fp))
    {
        size_t total_read = fread(buf, 1, sizeof(buf), fp);
        if(!SHA1_Update(&context, buf, total_read))
        {
            return NULL;
        }
    }
    fclose(fp);

    if(!SHA1_Final(sha1_digest, &context))
        return NULL;

    return sha1_digest;
}

It can be used as follows:

unsigned char *sha1digest = calculateSHA1("/tmp/file1");

The res variable contains the sha1 hash.

You can print it on the screen using the following for-loop:

char *sha1hash = (char *)malloc(sizeof(char) * 41);
sha1hash[41] = '\0';
int i;
for (i = 0; i < SHA_DIGEST_LENGTH; i++)
{
    sprintf(&sha1hash[i*2], "%02x", sha1digest[i]);
}
printf("SHA1 HASH: %s\n", sha1hash);

This is not possible to do with a textarea. What you are looking for is an content editable div, which is very easily done:

<div contenteditable="true"></div>

jsFiddle

div.editable {_x000D_
    width: 300px;_x000D_
    height: 200px;_x000D_
    border: 1px solid #ccc;_x000D_
    padding: 5px;_x000D_
}_x000D_
_x000D_
strong {_x000D_
  font-weight: bold;_x000D_
}

<div contenteditable="true">This is the first line.<br>_x000D_
See, how the text fits here, also if<br>there is a <strong>linebreak</strong> at the end?_x000D_
<br>It works nicely._x000D_
<br>_x000D_
<br><span style="color: lightgreen">Great</span>._x000D_
</div>

diplay: flex; for it's container and margin:auto; for it's item works perfect.

NOTE: You have to setup the width and height to see the effect.

#container{_x000D_
  width: 100%; /*width needs to be setup*/_x000D_
  height: 150px; /*height needs to be setup*/_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
.item{_x000D_
  margin: auto; /*These will make the item in center*/_x000D_
  background-color: #CCC;_x000D_
}

<div id="container">_x000D_
   <div class="item">CENTER</div>_x000D_
</div>

Len is what you want.

word = "habit"  
length = Len(word)

If none of the other answers work for you, it may be because you are binding the ContentProperty of a control in the OnLoad function, which means this won't work:

private void UserControl_Load(object sender, RoutedEventArgs e)
{
  Bind.SetBindingElement(labelName, String.Format("{0:0.00}", PropertyName), Label.ContentProperty) 
}

The solution is simple: there is a ContentStringFormat property in the xaml. So when you create the label do this:

//if you want the decimal places definite
<Label Content="0" Name="labelName" ContentStringFormat="0.00"/>

Or

//if you want the decimal places to be optional
<Label Content="0" Name="labelName" ContentStringFormat="0.##"/>

Example with preloader Dotnet 3.0 Core

ProgressMessageHandler processMessageHander = new ProgressMessageHandler();

processMessageHander.HttpSendProgress += (s, e) =>
{
    if (e.ProgressPercentage > 0)
    {
        ProgressPercentage = e.ProgressPercentage;
        TotalBytes = e.TotalBytes;
        progressAction?.Invoke(progressFile);
    }
};

using (var client = HttpClientFactory.Create(processMessageHander))
{
    var uri = new Uri(transfer.BackEndUrl);
    client.DefaultRequestHeaders.Authorization =
    new AuthenticationHeaderValue("Bearer", AccessToken);

    using (MultipartFormDataContent multiForm = new MultipartFormDataContent())
    {
        multiForm.Add(new StringContent(FileId), "FileId");
        multiForm.Add(new StringContent(FileName), "FileName");
        string hash = "";

        using (MD5 md5Hash = MD5.Create())
        {
            var sb = new StringBuilder();
            foreach (var data in md5Hash.ComputeHash(File.ReadAllBytes(FullName)))
            {
                sb.Append(data.ToString("x2"));
            }
            hash = result.ToString();
        }
        multiForm.Add(new StringContent(hash), "Hash");

        using (FileStream fs = File.OpenRead(FullName))
        {
            multiForm.Add(new StreamContent(fs), "file", Path.GetFileName(FullName));
            var response = await client.PostAsync(uri, multiForm);
            progressFile.Message = response.ToString();

            if (response.IsSuccessStatusCode) {
                progressAction?.Invoke(progressFile);
            } else {
                progressErrorAction?.Invoke(progressFile);
            }
            response.EnsureSuccessStatusCode();
        }
    }
}

Save below in a test.bat and It'll work for you:

@echo off

net use Z: \\server\SharedFolderName password /user:domain\Username /persistent:yes

/persistent:yes flag will tell the computer to automatically reconnect this share on logon. Otherwise, you need to run the script again during each boot to map the drive.

For Example:

net use Z: \\WindowsServer123\g$ P@ssw0rd /user:Mynetdomain\Sysadmin /persistent:yes

Here is a function I wrote to simplify things for myself:

It also returns shorthand versions of boolean, integer, double and real.

function type($mixed, $parseNumeric = false)
{        
    if ($parseNumeric && is_numeric($mixed)) {
        //Set type to relevant numeric format
        $mixed += 0;
    }
    $t = gettype($mixed);
    switch($t) {
        case 'boolean': return 'bool'; //shorthand
        case 'integer': return 'int';  //shorthand
        case 'double': case 'real': return 'float'; //equivalent for all intents and purposes
        default: return $t;
    }
}

Calling type with parseNumeric set to true will convert numeric strings before checking type.

Thus:

type("5", true) will return int

type("3.7", true) will return float

type("500") will return string

Just be careful since this is a kind of false checking method and your actual variable will still be a string. You will need to convert the actual variable to the correct type if needed. I just needed it to check if the database should load an item id or alias, thus not having any unexpected effects since it will be parsed as string at run time anyway.

Edit

If you would like to detect if objects are functions add this case to the switch:

case 'object': return is_callable($mixed)?'function':'object';

From the solutions in this thread, I came up with the following probably overcomplicated solution that lets you delay rendering any html (scripts too) within a using block.

USAGE

Create the "section"

1. Typical scenario: In a partial view, only include the block one time no matter how many times the partial view is repeated in the page:

   @using (Html.Delayed(isOnlyOne: "some unique name for this section")) {
       <script>
           someInlineScript();
       </script>
   }
   

2. In a partial view, include the block for every time the partial is used:

   @using (Html.Delayed()) {
       <b>show me multiple times, @Model.Whatever</b>
   }
   

3. In a partial view, only include the block once no matter how many times the partial is repeated, but later render it specifically by name when-i-call-you:

   @using (Html.Delayed("when-i-call-you", isOnlyOne: "different unique name")) {
       <b>show me once by name</b>
       <span>@Model.First().Value</span>
   }
   

Render the "sections"

(i.e. display the delayed section in a parent view)

@Html.RenderDelayed(); // writes unnamed sections (#1 and #2, excluding #3)
@Html.RenderDelayed("when-i-call-you", false); // writes the specified block, and ignore the `isOnlyOne` setting so we can dump it again
@Html.RenderDelayed("when-i-call-you"); // render the specified block by name
@Html.RenderDelayed("when-i-call-you"); // since it was "popped" in the last call, won't render anything due to `isOnlyOne` provided in `Html.Delayed`

}

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

Creating a property with only a getter makes your property read-only for any code that is outside the class.

You can however change the value using methods provided by your class :

public class FuelConsumption {
    private double fuel;
    public double Fuel
    {
        get { return this.fuel; }
    }
    public void FillFuelTank(double amount)
    {
        this.fuel += amount;
    }
}

public static void Main()
{
    FuelConsumption f = new FuelConsumption();

    double a;
    a = f.Fuel; // Will work
    f.Fuel = a; // Does not compile

    f.FillFuelTank(10); // Value is changed from the method's code
}

Setting the private field of your class as readonly allows you to set the field value only once (using an inline assignment or in the class constructor). You will not be able to change it later.

public class ReadOnlyFields {
    private readonly double a = 2.0;
    private readonly double b;

    public ReadOnlyFields()
    {
        this.b = 4.0;
    }
}

readonly class fields are often used for variables that are initialized during class construction, and will never be changed later on.

In short, if you need to ensure your property value will never be changed from the outside, but you need to be able to change it from inside your class code, use a "Get-only" property.

If you need to store a value which will never change once its initial value has been set, use a readonly field.

you have to declare current date into variables like this

 $(function() {
    var date = new Date();
    var currentMonth = date.getMonth();
    var currentDate = date.getDate();
    var currentYear = date.getFullYear();
    $('#datepicker').datepicker({
    minDate: new Date(currentYear, currentMonth, currentDate)
    });
})

HTML: Use names as

<input name="levels[level][]">
<input name="levels[build_time][]">

PHP:

$array = filter_input_array(INPUT_POST);
$newArray = array();
foreach (array_keys($array) as $fieldKey) {
    foreach ($array[$fieldKey] as $key=>$value) {
        $newArray[$key][$fieldKey] = $value;
    }
}  

$newArray will hold data as you want

Array ( 
  [0] => Array ( [level] => 1 [build_time] => 123 ) 
  [1] => Array ( [level] => 2 [build_time] => 456 )
)

You can use gethostname followed by gethostbyname to get your local interface internal IP.

This returned IP may be different from your external IP though. To get your external IP you would have to communicate with an external server that will tell you what your external IP is. Because the external IP is not yours but it is your routers.

//Example: b1 == 192, b2 == 168, b3 == 0, b4 == 100
struct IPv4
{
    unsigned char b1, b2, b3, b4;
};

bool getMyIP(IPv4 & myIP)
{
    char szBuffer[1024];

    #ifdef WIN32
    WSADATA wsaData;
    WORD wVersionRequested = MAKEWORD(2, 0);
    if(::WSAStartup(wVersionRequested, &wsaData) != 0)
        return false;
    #endif


    if(gethostname(szBuffer, sizeof(szBuffer)) == SOCKET_ERROR)
    {
      #ifdef WIN32
      WSACleanup();
      #endif
      return false;
    }

    struct hostent *host = gethostbyname(szBuffer);
    if(host == NULL)
    {
      #ifdef WIN32
      WSACleanup();
      #endif
      return false;
    }

    //Obtain the computer's IP
    myIP.b1 = ((struct in_addr *)(host->h_addr))->S_un.S_un_b.s_b1;
    myIP.b2 = ((struct in_addr *)(host->h_addr))->S_un.S_un_b.s_b2;
    myIP.b3 = ((struct in_addr *)(host->h_addr))->S_un.S_un_b.s_b3;
    myIP.b4 = ((struct in_addr *)(host->h_addr))->S_un.S_un_b.s_b4;

    #ifdef WIN32
    WSACleanup();
    #endif
    return true;
}

You can also always just use 127.0.0.1 which represents the local machine always.

Subnet mask in Windows:

You can get the subnet mask (and gateway and other info) by querying subkeys of this registry entry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces

Look for the registry value SubnetMask.

Other methods to get interface information in Windows:

You could also retrieve the information you're looking for by using: WSAIoctl with this option: SIO_GET_INTERFACE_LIST

While going through Microsoft MVC framework, I got a thought about builder pattern. I came across the pattern in the ControllerBuilder class. This class is to return the controller factory class, which is then used to build concrete controller.

Advantage I see in using builder pattern is that, you can create a factory of your own and plug it into the framework.

@Tetha, there can be a restaurant (Framework) run by Italian guy, that serves Pizza. In order to prepare pizza Italian guy (Object Builder) uses Owen (Factory) with a pizza base (base class).

Now Indian guy takes over the restaurant from Italian guy. Indian restaurant (Framework) servers dosa instead of pizza. In order to prepare dosa Indian guy (object builder) uses Frying Pan (Factory) with a Maida (base class)

If you look at scenario, food is different,way food is prepared is different, but in the same restaurant (under same framework). Restaurant should be build in such a way that it can support Chinese, Mexican or any cuisine. Object builder inside framework facilitates to plugin kind of cuisine you want. for example

class RestaurantObjectBuilder
{
   IFactory _factory = new DefaultFoodFactory();

   //This can be used when you want to plugin the 
   public void SetFoodFactory(IFactory customFactory)
   {
        _factory = customFactory;
   }

   public IFactory GetFoodFactory()
   {
      return _factory;
   }

Not very readable, but effective, has no dependencies and runs with any java version

byte[] buffer = new byte[1024];
for (int n; (n = inputStream.read(buffer)) != -1; outputStream.write(buffer, 0, n));

var pom = document.createElement('a');
pom.setAttribute('href', 'data:application/octet-stream,' + encodeURIComponent(text));
pom.setAttribute('download', filename);
pom.style.display = 'none';
document.body.appendChild(pom);
pom.click();
document.body.removeChild(pom);     

TO search a column name use the below query if you know the column name accurately:

select owner,table_name from all_tab_columns where upper(column_name) =upper('keyword');

TO search a column name if you dont know the accurate column use below:

select owner,table_name from all_tab_columns where upper(column_name) like upper('%keyword%');

You could change the lists to sets and then compare both sets using the & function. eg:

list1 = [1, 2, 3, 4, 5]
list2 = [5, 6, 7, 8, 9]

if set(list1) & set(list2):
    print "Number was found"
else:
    print "Number not in list"

The "&" operator gives the intersection point between the two sets. If there is an intersection, a set with the intersecting points will be returned. If there is no intersecting points then an empty set will be returned.

When you evaluate an empty set/list/dict/tuple with the "if" operator in Python the boolean False is returned.

Slightly altered version of Sven Marnach's solution..

import os

folder_location = 'C:\SomeFolderName'
file_list = create_file_list(folder_location)
def create_file_list(path):
return_list = []
for filenames in os.walk(path):
for file_list in filenames:
for file_name in file_list:
if file_name.endswith((".txt")):
return_list.append(file_name)
return return_list

When I want to develop insensitive case searchs, I always convert every string to lower case before do comparasion

You have to use CASE Statement/Expression

Select * from Customer
WHERE  (I.IsClose=@ISClose OR @ISClose is NULL)  
AND    
    (C.FirstName like '%'+@ClientName+'%' or @ClientName is NULL )    
AND 
     CASE @Value
         WHEN 2 THEN (CASE I.RecurringCharge WHEN @Total or @Total is NULL) 
         WHEN 3 THEN (CASE WHEN I.RecurringCharge like 
                               '%'+cast(@Total as varchar(50))+'%' 
                     or @Total is NULL )
     END

A scalar always holds a single element. Whatever is in a scalar variable is always a scalar. A reference is a scalar value.

If you want to know if it is a reference, you can use ref. If you want to know the reference type, you can use the reftype routine from Scalar::Util.

If you want to know if it is an object, you can use the blessed routine from Scalar::Util. You should never care what the blessed package is, though. UNIVERSAL has some methods to tell you about an object: if you want to check that it has the method you want to call, use can; if you want to see that it inherits from something, use isa; and if you want to see it the object handles a role, use DOES.

If you want to know if that scalar is actually just acting like a scalar but tied to a class, try tied. If you get an object, continue your checks.

If you want to know if it looks like a number, you can use looks_like_number from Scalar::Util. If it doesn't look like a number and it's not a reference, it's a string. However, all simple values can be strings.

If you need to do something more fancy, you can use a module such as Params::Validate.

The entity which has the table with foreign key in the database is the owning entity and the other table, being pointed at, is the inverse entity.

If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?

You need to declare timer outside the function. Otherwise, you get a brand new variable on each function invocation.

var timer;
function endAndStartTimer() {
  window.clearTimeout(timer);
  //var millisecBeforeRedirect = 10000; 
  timer = window.setTimeout(function(){alert('Hello!');},10000); 
}

In Eclipse it is very easy to point Tomcat to a new JVM (in this example JRE6). My problem was I couldn't find where to do it. Here is the trick:

1. On the ECLIPSE top menu FILE pull down tab, select NEW, -->Other
2. ...on the New Server: Select A Wizard window, select: Server-> Server... click NEXT
3. . on the New Server: Define a New Server window, select Apache> Tomcat 7 Server
4. ..now click the line in blue and underlined entitled: Configure Runtime Environments
5. on the Server Runtime Environments window,
6. ..select Apache, expand it(click on the arrow to the left), select TOMCAT v7.0, and click EDIT.
7. you will see a window called EDIT SERVER RUNTIME ENVIRONMENT: TOMCAT SERVER
8. On this screen there is a pulldown labeled JREs.
9. You should find your JRE listed like JRE1.6.0.33. If not use the Installed JRE button.
10. Select the desired JRE. Click the FINISH button.
11. Gracefully exit, in the Server: Server Runtime Environments window, click OK
12. in the New Server: Define a new Server window, hit NEXT
13. in the New Server: Add and Remove Window, select apps and install them on the server.
14. in the New Server: Add and Remove Window, click Finish

That's all. Interesting, only steps 7-10 seem to matter, and they will change the JRE used on all servers you have previously defined to use TOMCAT v7.0. The rest of the steps are just because I can't find any other way to get to the screen except by defining a new server. Does anyone else know an easier way?

If you call your event handler on markup, as you're doing now, you can't (x-browser). But if you bind the click event with jquery, it's possible the following way:

Markup:

  <a href="#" id="link1" >click</a>

Javascript:

  $(document).ready(function(){
      $("#link1").click(clickWithEvent);  //Bind the click event to the link
  });
  function clickWithEvent(evt){
     myFunc('p1', 'p2', 'p3');
     function myFunc(p1,p2,p3){  //Defined as local function, but has access to evt
        alert(evt.type);        
     }
  }

Since the event ob

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

None of the above solutions worked for me. For context, I'm running ubuntu, and I had already gone through the ssh-key setup documentation. The fix for me was to run ssh-add in the terminal. This fixed the issue.

java packages are base, and javax packages are extensions.

Swing was an extension because AWT was the original UI API. Swing came afterwards, in version 1.1.

Well, you can use the following regex:

^\d+$

In Symfony 4, you can use the ParameterBagInterface:

use Symfony\Component\DependencyInjection\ParameterBag\ParameterBagInterface;

class MessageGenerator
{
    private $params;

    public function __construct(ParameterBagInterface $params)
    {
        $this->params = $params;
    }

    public function someMethod()
    {
        $parameterValue = $this->params->get('parameter_name');
        // ...
    }
}

and in app/config/services.yaml:

parameters:
    locale: 'en'
    dir: '%kernel.project_dir%'

It works for me in both controller and form classes. More details can be found in the Symfony blog.

@qbzenker provided the most idiomatic method IMO

Here are a few alternatives:

In [28]: df.query('Col2 != Col2') # Using the fact that: np.nan != np.nan
Out[28]:
   Col1  Col2  Col3
1     0   NaN   0.0

In [29]: df[np.isnan(df.Col2)]
Out[29]:
   Col1  Col2  Col3
1     0   NaN   0.0

I've tried to find a "fit to screen" property but there is no such.

But setting widget's "maximumSize" to a "some big number" ( like 2000 x 2000 ) will automatically fit the widget to the parent widget space.

This regularly occurs when you change the extension on the JAR for ZIP, extract the zip content and make some modifications on files such as changing the MANIFEST.MF file which is a very common case, many times Eclipse doesn't generate the MANIFEST file as we want, or maybe we would like to modify the CLASS-PATH or the MAIN-CLASS values of it.

The problem occurs when you zip back the folder.

A valid Runnable/Executable JAR has the next structure:

myJAR (Main-Directory)
    |-META-INF (Mandatory)
             |-MANIFEST.MF (Mandatory Main-class: com.MainClass)
    |-com 
         |-MainClass.class (must to implement the main method, mandatory)
    |-properties files (optional)
    |-etc (optional)

If your JAR complies with these rules it will work doesn't matter if you build it manually by using a ZIP tool and then you changed the extension back to .jar

Once you're done try execute it on the command line using:

java -jar myJAR.jar 

When you use a zip tool to unpack, change files and zip again, normally the JAR structure changes to this structure which is incorrect, since another directory level is added on the top of the file system making it a corrupted file as is shown below:

**myJAR (Main-Directory)
    |-myJAR (creates another directory making the file corrupted)**
          |-META-INF (Mandatory)
                   |-MANIFEST.MF (Mandatory Main-class: com.MainClass)
          |-com 
              |-MainClass.class (must to implement the main method, mandatory)
          |-properties files (optional)
          |-etc (optional)

Return your promise , return deferred.promise.
It is the promise API that has the 'then' method.

https://docs.angularjs.org/api/ng/service/$q

Calling resolve does not return a promise it only signals the promise that the promise is resolved so it can execute the 'then' logic.

Basic pattern as follows, rinse and repeat

I have tried some other ways to iterate a huge array and found out that halving the array length and then iterating both halves in a single loop is faster. This performance difference can be seen while processing huge arrays.

var firstHalfLen =0;
var secondHalfLen = 0;
var count2=0;
var searchterm = "face";
var halfLen = arrayLength/2;
if(arrayLength%2==halfLen)
{
   firstHalfLen = Math.ceil(halfLen);
   secondHalfLen=Math.floor(halfLen);
}
else
{
   firstHalfLen=halfLen;
   secondHalfLen=halfLen;
}
for(var firstHalfCOunter=0,secondHalfCounter = arrayLength-secondHalfLen;
    firstHalfCOunter < firstHalfLen;
    firstHalfCOunter++)
{
  if(mainArray[firstHalfCOunter].search(new RegExp(searchterm, "i"))> -1)
  {
    count2+=1;
  }
  if(secondHalfCounter < arrayLength)
  {
    if(mainArray[secondHalfCounter].search(new RegExp(searchterm, "i"))> -1)
    {
        count2+=1;
    }
    secondHalfCounter++; 
  }
}

Some performance comparison (using timer.js) between the cached length for-loop VS the above method.

The text inside $type is substituted directly into the insert string, therefore MySQL gets this:

... VALUES(testing, 'john', 'whatever')

Notice that there are no quotes around testing, you need to put these in like so:

$type = 'testing';
mysql_query("INSERT INTO contents (type, reporter, description) VALUES('$type', 'john', 'whatever')");

I also recommend you read up on SQL injection, as this sort of parameter passing is prone to hacking attempts if you do not sanitize the data being used:

• MySQL - SQL Injection Prevention

Much easier way:

$('#test').css('textTransform', 'capitalize');

I have to give @Dementic some credit for leading me down the right path. Far simpler than whatever you guys are proposing.

Here is a way to calculate memory usage of currently running application:

public static long getUsedMemorySize() {

    long freeSize = 0L;
    long totalSize = 0L;
    long usedSize = -1L;
    try {
        Runtime info = Runtime.getRuntime();
        freeSize = info.freeMemory();
        totalSize = info.totalMemory();
        usedSize = totalSize - freeSize;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return usedSize;

}

Not gonna happen with CSS only

Inline javascript

<a href='index.html' 
    onmouseover='this.style.textDecoration="none"' 
    onmouseout='this.style.textDecoration="underline"'>
    Click Me
</a>

In a working draft of the CSS2 spec it was declared that you could use pseudo-classes inline like this:

<a href="http://www.w3.org/Style/CSS"
   style="{color: blue; background: white}  /* a+=0 b+=0 c+=0 */
      :visited {color: green}           /* a+=0 b+=1 c+=0 */
      :hover {background: yellow}       /* a+=0 b+=1 c+=0 */
      :visited:hover {color: purple}    /* a+=0 b+=2 c+=0 */
     ">
</a>

but it was never implemented in the release of the spec as far as I know.

http://www.w3.org/TR/2002/WD-css-style-attr-20020515#pseudo-rules

Yes, set the cell as a RANGE object one time and then use that RANGE object in your code:

Sub RangeExample()
Dim MyRNG As Range

Set MyRNG = Sheets("Sheet1").Cells(23, 4)

Debug.Print MyRNG.Value

End Sub

Alternately you can simply store the value of that cell in memory and reference the actual value, if that's all you really need. That variable can be Long or Double or Single if numeric, or String:

Sub ValueExample()
Dim MyVal As String

MyVal = Sheets("Sheet1").Cells(23, 4).Value

Debug.Print MyVal

End Sub

In simplejson (or the library json in Python 2.6 and later), loads takes a JSON string and returns a Python data structure, dumps takes a Python data structure and returns a JSON string. JSON string can encode Javascript arrays, not just objects, and a Python list corresponds to a JSON string encoding an array. To get a JSON string such as

{"apple":"cat", "banana":"dog"}

the Python object you pass to json.dumps could be:

dict(apple="cat", banana="dog")

though the JSON string is also valid Python syntax for the same dict. I believe the specific string you say you expect is simply invalid JSON syntax, however.

Thats easy!

Mark the section you want to collapse and,

Ctrl+M+H

And to expand use '+' mark on its left.

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

CAVEAT: Please remove anonymous users !!!

Yes, you can even change it by triggering an event

<input type='text' name='pass'  onclick="(this.type='password')" />


<input type="text" placeholder="date" onfocusin="(this.type='date')" onfocusout="(this.type='text')">

In one line, using a lambda:

timestamps.sort(key=lambda x: time.strptime(x, '%Y-%m-%d %H:%M:%S')[0:6], reverse=True)

Passing a function to list.sort:

def foo(x):
    return time.strptime(x, '%Y-%m-%d %H:%M:%S')[0:6]

timestamps.sort(key=foo, reverse=True)

=$G1="X"

would be the correct (and easiest) method. Just select the entire sheet first, as conditional formatting only works on selected cells. I just tried it and it works perfectly. You must start at G1 rather than G2 otherwise it will offset the conditional formatting by a row.

On my side, I used, with a form application:

String Directory = System.Windows.Forms.Application.StartupPath;

it takes the application startup path.

Your query should be SELECT * FROM `table` WHERE find_in_set(interests, "sports,pub")>0

What I understand is that you store the interests in one field of your table, which is a misconception. You should definitively have an "interest" table.

In my case is a cookie-related issue, I had many cookies with value extremely big, and that was causing the problem.

You can replicate this issue here on stackoverflow.com, just open the console and type this:

[ ...Array(5) ].forEach((i, idx) => {
    document.cookie = `stackoverflow_cookie${idx}=${'a'.repeat(4000)}`;
});

What is that?

I am creating 5 cookies with a string of length or value of 4000 bytes; then reload the page and you will see the same issue.

I tried it on google.com and you'll get the error but they automatically clear the cookies for you, which is a nice fallback to start fresh.

you can use json_decode function

foreach (json_decode($response) as $area)
{
 print_r($area); // this is your area from json response
}

See this fiddle

lets say all your static assets are in a folder "static" at the root level and you want copy them to the build folder maintaining the structure of subfolder, then in your entry file) just put

//index.js or index.jsx

require.context("!!file?name=[path][name].[ext]&context=./static!../static/", true, /^\.\/.*\.*/);

Declaration says "this thing exists somewhere":

int foo();       // function
extern int bar;  // variable
struct T
{
   static int baz;  // static member variable
};

Definition says "this thing exists here; make memory for it":

int foo() {}     // function
int bar;         // variable
int T::baz;      // static member variable

Initialisation is optional at the point of definition for objects, and says "here is the initial value for this thing":

int bar = 0;     // variable
int T::baz = 42; // static member variable

Sometimes it's possible at the point of declaration instead:

struct T
{
   static int baz = 42;
};

…but that's getting into more complex features.

Its a common error which happens when we try to access a database which doesn't exist. So create the database using

CREATE DATABASE blog_development;

The error commonly occours when we have dropped the database using

DROP DATABASE blog_development;

and then try to access the database.

The methods viewWillLayoutSubviews and viewDidLayoutSubviews aren't mentioned in the diagrams, but these are called between viewWillAppear and viewDidAppear. They can be called multiple times.

This situation occured if there are object in repository, which creates by current transaction.

Simple scenario:

1. checkout some directory two times, as DIR1 and DIR2
2. make 'svn mkdir test' in both
3. make commit from DIR1
4. try to make commit DIR2 (without svn up), SVN shall return this error

Same thing when adding same files from two working copies.

Try it like :

File.save(csvInput, function (content) {
    var hiddenElement = document.createElement('a');

    hiddenElement.href = 'data:attachment/csv,' + encodeURI(content);
    hiddenElement.target = '_blank';
    hiddenElement.download = 'myFile.csv';
    hiddenElement.click();
});

based on the most excellent answer in this question

this should work:

private void cleanlistbox(object sender, EventArgs e)
{
    listBox1.Items.Clear( );
}

You can use != operator to check for inequality. Moreover in python 2 there was <> operator which used to do the same thing but it has been deprecated in python 3

The internal storage is referred to as "external storage" in the API.

As mentioned in the Environment documentation

Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer.

To distinguish whether "Environment.getExternalStorageDirectory()" actually returned physically internal or external storage, call Environment.isExternalStorageEmulated(). If it's emulated, than it's internal. On newer devices that have internal storage and sdcard slot Environment.getExternalStorageDirectory() will always return the internal storage. While on older devices that have only sdcard as a media storage option it will always return the sdcard.

There is no way to retrieve all storages using current Android API.

I've created a helper based on Vitaliy Polchuk's method in the answer below

How can I get the list of mounted external storage of android device

NOTE: starting KitKat secondary storage is accessible only as READ-ONLY, you may want to check for writability using the following method

/**
 * Checks whether the StorageVolume is read-only
 * 
 * @param volume
 *            StorageVolume to check
 * @return true, if volume is mounted read-only
 */
public static boolean isReadOnly(@NonNull final StorageVolume volume) {
    if (volume.mFile.equals(Environment.getExternalStorageDirectory())) {
        // is a primary storage, check mounted state by Environment
        return android.os.Environment.getExternalStorageState().equals(
                android.os.Environment.MEDIA_MOUNTED_READ_ONLY);
    } else {
        if (volume.getType() == Type.USB) {
            return volume.isReadOnly();
        }
        //is not a USB storagem so it's read-only if it's mounted read-only or if it's a KitKat device
        return volume.isReadOnly() || Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
    }
}

Indeed, you must initialize your array then right after that use array.push() command line.

var array = new Array();
array.push("first value");
array.push("second value");

Back in the day I found that Rdb, the former DEC product now supported by Oracle allowed the column alias to be used in the GROUP BY. Mainstream Oracle through version 11 does not allow the column alias to be used in the GROUP BY. Not sure what Postgresql, SQL Server, MySQL, etc will or won't allow. YMMV.

This worked for me for printing response with header:

wget --server-response http://www.example.com/

                       CultureInfo.InvariantCulture,

That's not the right way to set the permissions as you are overwriting them with each method call.

Replace this:

mButtonLogin.setReadPermissions("user_friends");
mButtonLogin.setReadPermissions("public_profile");
mButtonLogin.setReadPermissions("email");
mButtonLogin.setReadPermissions("user_birthday");

With the following, as the method setReadPermissions() accepts an ArrayList:

loginButton.setReadPermissions(Arrays.asList(
        "public_profile", "email", "user_birthday", "user_friends"));

Also here is how to query extra data GraphRequest:

private LoginButton loginButton;
private CallbackManager callbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

    loginButton = (LoginButton) findViewById(R.id.login_button);

    loginButton.setReadPermissions(Arrays.asList(
            "public_profile", "email", "user_birthday", "user_friends"));

    callbackManager = CallbackManager.Factory.create();

    // Callback registration
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // App code
            GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(JSONObject object, GraphResponse response) {
                            Log.v("LoginActivity", response.toString());

                            // Application code
                            String email = object.getString("email");
                            String birthday = object.getString("birthday"); // 01/31/1980 format
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender,birthday");
            request.setParameters(parameters);
            request.executeAsync();


        }

        @Override
        public void onCancel() {
            // App code
            Log.v("LoginActivity", "cancel");
        }

        @Override
        public void onError(FacebookException exception) {
            // App code
            Log.v("LoginActivity", exception.getCause().toString());
        }
    });
}

EDIT:

One possible problem is that Facebook assumes that your email is invalid. To test it, use the Graph API Explorer and try to get it. If even there you can't get your email, change it in your profile settings and try again. This approach resolved this issue for some developers commenting my answer.

You can use the partial function from functools like so.

from functools import partial

def perform(f):
    f()

perform(Action1)
perform(partial(Action2, p))
perform(partial(Action3, p, r))

Also works with keywords

perform(partial(Action4, param1=p))

Try this, It always works, and you will get NO TypeError:

try{

    var i1 = document.getElementById('i1');
    var i2 = document.getElementById('i2');
    var __i = {'user' : document.getElementsByName("username")[0], 'pass' : document.getElementsByName("password")[0] };
    if(  __i.user.value.length >= 1 ) { i1.value = ''; } else { i1.value = 'Acc'; }
    if(  __i.pass.value.length >= 1 ) { i2.value = ''; } else { i2.value = 'Pwd'; }

}catch(e){
    if(e){
    // If fails, Do something else
    }
}

You can use this method also

sed 'x;G;1!h;s/\n/ /g;$!d'

Explanation

x   - which is used to exchange the data from both space (pattern and hold).
G   - which is used to append the data from hold space to pattern space.
h   - which is used to copy the pattern space to hold space.
1!h - During first line won't copy pattern space to hold space due to \n is
      available in pattern space.
$!d - Clear the pattern space every time before getting next line until the
      last line.

Flow:
When the first line get from the input, exchange is made, so 1 goes to hold space and \n comes to pattern space, then appending the hold space to pattern space, and then substitution is performed and deleted the pattern space.
During the second line exchange is made, 2 goes to hold space and 1 comes to pattern space, then G append the hold space into the pattern space, then h copy the pattern to it and substitution is made and deleted. This operation is continued until eof is reached then print exact result.

Is that your actual code? A javascript object (which is what you've given us) does not have a length property, so in this case exampleArray.length returns undefined rather than 5.

This stackoverflow explains the length differences between an object and an array, and this stackoverflow shows how to get the 'size' of an object.

Short 'n Sweet

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

Example

escapeRegExp("All of these should be escaped: \ ^ $ * + ? . ( ) | { } [ ]");

>>> "All of these should be escaped: \\ \^ \$ \* \+ \? \. \( \) \| \{ \} \[ \] "

(NOTE: the above is not the original answer; it was edited to show the one from MDN. This means it does not match what you will find in the code in the below npm, and does not match what is shown in the below long answer. The comments are also now confusing. My recommendation: use the above, or get it from MDN, and ignore the rest of this answer. -Darren,Nov 2019)

Install

Available on npm as escape-string-regexp

npm install --save escape-string-regexp

Note

See MDN: Javascript Guide: Regular Expressions

Other symbols (~`!@# ...) MAY be escaped without consequence, but are not required to be.

Test Case: A typical url

escapeRegExp("/path/to/resource.html?search=query");

>>> "\/path\/to\/resource\.html\?search=query"

The Long Answer

If you're going to use the function above at least link to this stack overflow post in your code's documentation so that it doesn't look like crazy hard-to-test voodoo.

var escapeRegExp;

(function () {
  // Referring to the table here:
  // https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/regexp
  // these characters should be escaped
  // \ ^ $ * + ? . ( ) | { } [ ]
  // These characters only have special meaning inside of brackets
  // they do not need to be escaped, but they MAY be escaped
  // without any adverse effects (to the best of my knowledge and casual testing)
  // : ! , = 
  // my test "~!@#$%^&*(){}[]`/=?+\|-_;:'\",<.>".match(/[\#]/g)

  var specials = [
        // order matters for these
          "-"
        , "["
        , "]"
        // order doesn't matter for any of these
        , "/"
        , "{"
        , "}"
        , "("
        , ")"
        , "*"
        , "+"
        , "?"
        , "."
        , "\\"
        , "^"
        , "$"
        , "|"
      ]

      // I choose to escape every character with '\'
      // even though only some strictly require it when inside of []
    , regex = RegExp('[' + specials.join('\\') + ']', 'g')
    ;

  escapeRegExp = function (str) {
    return str.replace(regex, "\\$&");
  };

  // test escapeRegExp("/path/to/res?search=this.that")
}());

You can use the getimagesize function like this:

list($width, $height) = getimagesize('path to image');
echo "width: " . $width . "<br />";
echo "height: " .  $height;

When thread tA call tB.join() its causes not only waits for tB to die or tA be interrupted itself but create happens-before relation between last statement in tB and next statement after tB.join() in tA thread.

All actions in a thread happen-before any other thread successfully returns from a join() on that thread.

It means program

class App {
    // shared, not synchronized variable = bad practice
    static int sharedVar = 0;
    public static void main(String[] args) throws Exception {
        Thread threadB = new Thread(() -> {sharedVar = 1;});
        threadB.start();
        threadB.join();

        while (true) 
            System.out.print(sharedVar);
    }
}

Always print

>> 1111111111111111111111111 ...

But program

class App {
    // shared, not synchronized variable = bad practice
    static int sharedVar = 0;
    public static void main(String[] args) throws Exception {
        Thread threadB = new Thread(() -> {sharedVar = 1;});
        threadB.start();
        // threadB.join();  COMMENT JOIN

        while (true)
            System.out.print(sharedVar);
    }
}

Can print not only

>> 0000000000 ... 000000111111111111111111111111 ...

But

>> 00000000000000000000000000000000000000000000 ... 

Always only '0'.

Because Java Memory Model don't require 'transfering' new value of 'sharedVar' from threadB to main thread without heppens-before relation (thread start, thread join, usage of 'synchonized' keyword, usage of AtomicXXX variables, etc).

I like checking the orientation notification because you can add this feature in any class, no needs to be a view or a view controller. Even in your app delegate.

SWIFT 5:

    //ask the system to start notifying when interface change
    UIDevice.current.beginGeneratingDeviceOrientationNotifications()
    //add the observer
    NotificationCenter.default.addObserver(
        self,
        selector: #selector(orientationChanged(notification:)),
        name: UIDevice.orientationDidChangeNotification,
        object: nil)

than caching the notification

    @objc func orientationChanged(notification : NSNotification) {
        //your code there
    }

To merge a local directory into a directory within an image, do this. It will not delete files already present within the image. It will only add files that are present locally, overwriting the files in the image if a file of the same name already exists.

COPY ./files/. /files/

Isn't it difficult even for humans to distinguish between a bottle and a can in the second image (provided the transparent region of the bottle is hidden)?

They are almost the same except for a very small region (that is, width at the top of the can is a little small while the wrapper of the bottle is the same width throughout, but a minor change right?)

The first thing that came to my mind was to check for the red top of bottle. But it is still a problem, if there is no top for the bottle, or if it is partially hidden (as mentioned above).

The second thing I thought was about the transparency of bottle. OpenCV has some works on finding transparent objects in an image. Check the below links.

• OpenCV Meeting Notes Minutes 2012-03-19

• OpenCV Meeting Notes Minutes 2012-02-28

Particularly look at this to see how accurately they detect glass:

• OpenCV Meeting Notes Minutes 2012-04-24

See their implementation result:

They say it is the implementation of the paper "A Geodesic Active Contour Framework for Finding Glass" by K. McHenry and J. Ponce, CVPR 2006.

It might be helpful in your case a little bit, but problem arises again if the bottle is filled.

So I think here, you can search for the transparent body of the bottles first or for a red region connected to two transparent objects laterally which is obviously the bottle. (When working ideally, an image as follows.)

Now you can remove the yellow region, that is, the label of the bottle and run your algorithm to find the can.

Anyway, this solution also has different problems like in the other solutions.

1. It works only if your bottle is empty. In that case, you will have to search for the red region between the two black colors (if the Coca Cola liquid is black).
2. Another problem if transparent part is covered.

But anyway, if there are none of the above problems in the pictures, this seems be to a better way.

One trick is to create an interface that extends a generic base interface...

public interface LoadFutures extends Map<UUID, Future<LoadResult>> {}

Then you can check it with instanceof before the cast...

Object obj = context.getAttribute(FUTURES);
if (!(obj instanceof LoadFutures)) {
    String format = "Servlet context attribute \"%s\" is not of type "
            + "LoadFutures. Its type is %s.";
    String msg = String.format(format, FUTURES, obj.getClass());
    throw new RuntimeException(msg);
}
return (LoadFutures) obj;

Mr.Iam4fun your code answer here..You will use thread...

   findViewById(R.id.download).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            new Thread(new Runnable() {
                public void run() {
                    DownloadFiles();
                }
            }).start();

And,then..

 public void DownloadFiles(){

        try {
            URL u = new URL("http://www.qwikisoft.com/demo/ashade/20001.kml");
            InputStream is = u.openStream();

            DataInputStream dis = new DataInputStream(is);

            byte[] buffer = new byte[1024];
            int length;

            FileOutputStream fos = new FileOutputStream(new File(Environment.getExternalStorageDirectory() + "/" + "data/test.kml"));
            while ((length = dis.read(buffer))>0) {
              fos.write(buffer, 0, length);
            }

          } catch (MalformedURLException mue) {
            Log.e("SYNC getUpdate", "malformed url error", mue);
          } catch (IOException ioe) {
            Log.e("SYNC getUpdate", "io error", ioe);
          } catch (SecurityException se) {
            Log.e("SYNC getUpdate", "security error", se);
          }
}
}

Sure, it will be working..

I think for gradle version it uses gradle/wrapper/gradle-wrapper.properties under the hood.

For .Net core i had many problems using SSH.net and also its deprecated. I tried a few other libraries, even for other programming languages. But i found a very good alternative. https://stackoverflow.com/a/64443701/8529170

One line version: long n = strtol(s.c_str(), NULL, base); .

(s is the string, and base is an int such as 2, 8, 10, 16.)

You can refer to this link for more details of strtol.

The core idea is to use strtol function, which is included in cstdlib.

Since strtol only handles with char array, we need to convert string to char array. You can refer to this link.

An example:

#include <iostream>
#include <string>   // string type
#include <bitset>   // bitset type used in the output

int main(){
    s = "1111000001011010";
    long t = strtol(s.c_str(), NULL, 2); // 2 is the base which parse the string

    cout << s << endl;
    cout << t << endl;
    cout << hex << t << endl;
    cout << bitset<16> (t) << endl;

    return 0;
}

which will output:

1111000001011010
61530
f05a
1111000001011010

I don't know what kind of homework this is, but most probably the teacher doesn't want an answer where you just call a "magical" existing function (even though that's the recommended way to do it), but he wants to see if you can implement this by your own.

Back in the days, my teacher used to say something like "I want to see if you can program by yourself, not if you can find it in the system." Well, how wrong he was ;) ..

Anyway, if your teacher is the same, here is the hard way to do it..

std::string LongToString(long value)
{
  std::string output;
  std::string sign;

  if(value < 0)
  {
    sign + "-";
    value = -value;
  }

  while(output.empty() || (value > 0))
  {
    output.push_front(value % 10 + '0')
    value /= 10;
  }

  return sign + output;
}

You could argue that using std::string is not "the hard way", but I guess what counts in the actual agorithm.

In Managed C++, static class syntax is:-

public ref class BitParser abstract sealed
{
    public:
        static bool GetBitAt(...)
        {

        }
}

Check out BoxShadow and BoxDecoration

A Container can take a BoxDecoration (going off of the code you had originally posted) which takes a boxShadow

return Container(

  height: double.infinity,
  width: double.infinity,
  decoration: BoxDecoration(

Add a column to the query which can sub identify the data to sort on that.

In the below example I use a Common Table Expression with the selects you showed which places them in specific groups in the CTE, and then do a union off of both of those groups into AllStudents.

The final select will then sort AllStudents by the SortIndex column first and then by the name such as:

WITH Juveniles as
(
      Select 1 as [SortIndex], id,name,age From Student
      Where age < 15
),

AStudents as
(
      Select 2 as [SortIndex], id,name,age From Student
      Where Name like "%a%" 
),

AllStudents as
(
      select * from Juveniles
      union 
      select * from AStudents
)

select * from AllStudents
sort by [SortIndex], name;

To summarize, it will get all the students which will be sorted by group first, and subsorted by the name within the group after that.

The ngRoute module is no longer part of the core angular.js file. If you are continuing to use $routeProvider then you will now need to include angular-route.js in your HTML:

<script src="angular.js">
<script src="angular-route.js">

API Reference

You also have to add ngRoute as a dependency for your application:

var app = angular.module('MyApp', ['ngRoute', ...]);

If instead you are planning on using angular-ui-router or the like then just remove the $routeProvider dependency from your module .config() and substitute it with the relevant provider of choice (e.g. $stateProvider). You would then use the ui.router dependency:

var app = angular.module('MyApp', ['ui.router', ...]);

Installing the OpenJDK Development Kit (JDK) should fix your problem.

sudo apt-get install openjdk-X-jdk

Probably the best way to check for errors in runtime API code is to define an assert style handler function and wrapper macro like this:

#define gpuErrchk(ans) { gpuAssert((ans), __FILE__, __LINE__); }
inline void gpuAssert(cudaError_t code, const char *file, int line, bool abort=true)
{
   if (code != cudaSuccess) 
   {
      fprintf(stderr,"GPUassert: %s %s %d\n", cudaGetErrorString(code), file, line);
      if (abort) exit(code);
   }
}

You can then wrap each API call with the gpuErrchk macro, which will process the return status of the API call it wraps, for example:

gpuErrchk( cudaMalloc(&a_d, size*sizeof(int)) );

If there is an error in a call, a textual message describing the error and the file and line in your code where the error occurred will be emitted to stderr and the application will exit. You could conceivably modify gpuAssert to raise an exception rather than call exit() in a more sophisticated application if it were required.

A second related question is how to check for errors in kernel launches, which can't be directly wrapped in a macro call like standard runtime API calls. For kernels, something like this:

kernel<<<1,1>>>(a);
gpuErrchk( cudaPeekAtLastError() );
gpuErrchk( cudaDeviceSynchronize() );

will firstly check for invalid launch argument, then force the host to wait until the kernel stops and checks for an execution error. The synchronisation can be eliminated if you have a subsequent blocking API call like this:

kernel<<<1,1>>>(a_d);
gpuErrchk( cudaPeekAtLastError() );
gpuErrchk( cudaMemcpy(a_h, a_d, size * sizeof(int), cudaMemcpyDeviceToHost) );

in which case the cudaMemcpy call can return either errors which occurred during the kernel execution or those from the memory copy itself. This can be confusing for the beginner, and I would recommend using explicit synchronisation after a kernel launch during debugging to make it easier to understand where problems might be arising.

Note that when using CUDA Dynamic Parallelism, a very similar methodology can and should be applied to any usage of the CUDA runtime API in device kernels, as well as after any device kernel launches:

#include <assert.h>
#define cdpErrchk(ans) { cdpAssert((ans), __FILE__, __LINE__); }
__device__ void cdpAssert(cudaError_t code, const char *file, int line, bool abort=true)
{
   if (code != cudaSuccess)
   {
      printf("GPU kernel assert: %s %s %d\n", cudaGetErrorString(code), file, line);
      if (abort) assert(0);
   }
}

add this function to your global.asax

protected void Application_AuthenticateRequest(Object sender, EventArgs e)
{
    string cookieName = FormsAuthentication.FormsCookieName;
    HttpCookie authCookie = Context.Request.Cookies[cookieName];

    if (authCookie == null)
    {
        return;
    }
    FormsAuthenticationTicket authTicket = null;
    try
    {
        authTicket = FormsAuthentication.Decrypt(authCookie.Value);
    }
    catch
    {
        return;
    }
    if (authTicket == null)
    {
        return;
    }
    string[] roles = authTicket.UserData.Split(new char[] { '|' });
    FormsIdentity id = new FormsIdentity(authTicket);
    GenericPrincipal principal = new GenericPrincipal(id, roles);

    Context.User = principal;
}

then you can use HttpContext.Current.User.Identity.Name to get username. hope it helps

Use an array, not a string, as given as guidance in BashFAQ #50.

Using a string is extremely bad security practice: Consider the case where password (or a where clause in the query, or any other component) is user-provided; you don't want to eval a password containing $(rm -rf .)!

There are two big considerations that the original poster needs to consider:

1. Are there keyspace clobbering issues? For example, {'a_b':{'c':1}, 'a':{'b_c':2}} would result in {'a_b_c':???}. The below solution evades the problem by returning an iterable of pairs.
2. If performance is an issue, does the key-reducer function (which I hereby refer to as 'join') require access to the entire key-path, or can it just do O(1) work at every node in the tree? If you want to be able to say joinedKey = '_'.join(*keys), that will cost you O(N^2) running time. However if you're willing to say nextKey = previousKey+'_'+thisKey, that gets you O(N) time. The solution below lets you do both (since you could merely concatenate all the keys, then postprocess them).

(Performance is not likely an issue, but I'll elaborate on the second point in case anyone else cares: In implementing this, there are numerous dangerous choices. If you do this recursively and yield and re-yield, or anything equivalent which touches nodes more than once (which is quite easy to accidentally do), you are doing potentially O(N^2) work rather than O(N). This is because maybe you are calculating a key a then a_1 then a_1_i..., and then calculating a then a_1 then a_1_ii..., but really you shouldn't have to calculate a_1 again. Even if you aren't recalculating it, re-yielding it (a 'level-by-level' approach) is just as bad. A good example is to think about the performance on {1:{1:{1:{1:...(N times)...{1:SOME_LARGE_DICTIONARY_OF_SIZE_N}...}}}})

Below is a function I wrote flattenDict(d, join=..., lift=...) which can be adapted to many purposes and can do what you want. Sadly it is fairly hard to make a lazy version of this function without incurring the above performance penalties (many python builtins like chain.from_iterable aren't actually efficient, which I only realized after extensive testing of three different versions of this code before settling on this one).

from collections import Mapping
from itertools import chain
from operator import add

_FLAG_FIRST = object()

def flattenDict(d, join=add, lift=lambda x:x):
    results = []
    def visit(subdict, results, partialKey):
        for k,v in subdict.items():
            newKey = lift(k) if partialKey==_FLAG_FIRST else join(partialKey,lift(k))
            if isinstance(v,Mapping):
                visit(v, results, newKey)
            else:
                results.append((newKey,v))
    visit(d, results, _FLAG_FIRST)
    return results

To better understand what's going on, below is a diagram for those unfamiliar with reduce(left), otherwise known as "fold left". Sometimes it is drawn with an initial value in place of k0 (not part of the list, passed into the function). Here, J is our join function. We preprocess each k_n with lift(k).

               [k0,k1,...,kN].foldleft(J)
                           /    \
                         ...    kN
                         /
       J(k0,J(k1,J(k2,k3)))
                       /  \
                      /    \
           J(J(k0,k1),k2)   k3
                    /   \
                   /     \
             J(k0,k1)    k2
                 /  \
                /    \
               k0     k1

This is in fact the same as functools.reduce, but where our function does this to all key-paths of the tree.

>>> reduce(lambda a,b:(a,b), range(5))
((((0, 1), 2), 3), 4)

Demonstration (which I'd otherwise put in docstring):

>>> testData = {
        'a':1,
        'b':2,
        'c':{
            'aa':11,
            'bb':22,
            'cc':{
                'aaa':111
            }
        }
    }
from pprint import pprint as pp

>>> pp(dict( flattenDict(testData, lift=lambda x:(x,)) ))
{('a',): 1,
 ('b',): 2,
 ('c', 'aa'): 11,
 ('c', 'bb'): 22,
 ('c', 'cc', 'aaa'): 111}

>>> pp(dict( flattenDict(testData, join=lambda a,b:a+'_'+b) ))
{'a': 1, 'b': 2, 'c_aa': 11, 'c_bb': 22, 'c_cc_aaa': 111}    

>>> pp(dict( (v,k) for k,v in flattenDict(testData, lift=hash, join=lambda a,b:hash((a,b))) ))
{1: 12416037344,
 2: 12544037731,
 11: 5470935132935744593,
 22: 4885734186131977315,
 111: 3461911260025554326}

[unimportant historical note due to moderation issues]

Regarding the alleged duplicate of Flatten a dictionary of dictionaries (2 levels deep) of lists in Python:

That question's solution can be implemented in terms of this one by doing sorted( sum(flatten(...),[]) ). The reverse is not possible: while it is true that the values of flatten(...) can be recovered from the alleged duplicate by mapping a higher-order accumulator, one cannot recover the keys. (edit: Also it turns out that the alleged duplicate owner's question is completely different, in that it only deals with dictionaries exactly 2-level deep, though one of the answers on that page gives a general solution.)

check for this by calling the library jquery after the noconflict.js or that this calling more than once jquery library after the noconflict.js

Conditional comment is a comment starts with <!--[if IE]> which couldn't be read by any browser except IE.

from 2011 Conditional comment isn't supported starting form IE 10 as announced by Microsoft in that time https://msdn.microsoft.com/en-us/library/hh801214(v=vs.85).aspx

The only option to use the Conditional comments is to request IE to run your site as IE 9 which supports the Conditional comments.

you can write your own css and/or js files for ie only and other browsers won't load or execute it.

this code snippet shows how to make IE 10 or 11 run ie-only.css and ie-only.js which contains custom codes to solve IE compatibility issues.

    <html>
      <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9">
      <!--[if IE]>
            <meta http-equiv="Content-Type" content="text/html; charset=Unicode">
            <link rel="stylesheet" type="text/css" href='/css/ie-only.css' />
            <script src="/js/ie-only.js"></script>

Exclamation mark makes any function always return a boolean.
The final value is the negation of the value returned by the function.

!function bool() { return false; }() // true
!function bool() { return true; }() // false

Omitting ! in the above examples would be a SyntaxError.

function bool() { return true; }() // SyntaxError

However, a better way to achieve this would be:

(function bool() { return true; })() // true

To get a type that implements io.Reader from a []byte slice, you can use bytes.NewReader in the bytes package:

r := bytes.NewReader(byteData)

This will return a value of type bytes.Reader which implements the io.Reader (and io.ReadSeeker) interface.

Don't worry about them not being the same "type". io.Reader is an interface and can be implemented by many different types. To learn a little bit more about interfaces in Go, read Effective Go: Interfaces and Types.

In my case I was using jackson-databind-2.8.8.jar that is not compatible with JDK 1.6 I need to use so Spring wasn't loading this converter. I downgraded the version and it works now.

I like Tony approach. It works, but I decided to implement in different way. Here my comments:

1) I did some tests and when using ng-style, Angular evaluates ng-style content, I mean getTableHeight() function more than once. I put a breakpoint into getTableHeight() function to analyze this.

By the way, ui-if was removed. Now you have ng-if build-in.

2) I prefer to write a service like this:

angular.module('angularStart.services').factory('uiGridService', function ($http, $rootScope) {

var factory = {};

factory.getGridHeight = function(gridOptions) {

    var length = gridOptions.data.length;
    var rowHeight = 30; // your row height
    var headerHeight = 40; // your header height
    var filterHeight = 40; // your filter height

    return length * rowHeight + headerHeight + filterHeight + "px";
}
factory.removeUnit = function(value, unit) {

    return value.replace(unit, '');
}
return factory;

});

And then in the controller write the following:

  angular.module('app',['ui.grid']).controller('AppController', ['uiGridConstants', function(uiGridConstants) {

  ...

  // Execute this when you have $scope.gridData loaded...
  $scope.gridHeight = uiGridService.getGridHeight($scope.gridData);

And at the HTML file:

  <div id="grid1" ui-grid="gridData" class="grid" ui-grid-auto-resize style="height: {{gridHeight}}"></div>

When angular applies the style, it only has to look in the $scope.gridHeight variable and not to evaluate a complete function.

3) If you want to calculate dynamically the height of an expandable grid, it is more complicated. In this case, you can set expandableRowHeight property. This fixes the reserved height for each subgrid.

    $scope.gridData = {
        enableSorting: true,
        multiSelect: false,  
        enableRowSelection: true,
        showFooter: false,
        enableFiltering: true,    
        enableSelectAll: false,
        enableRowHeaderSelection: false, 
        enableGridMenu: true,
        noUnselect: true,
        expandableRowTemplate: 'subGrid.html',
        expandableRowHeight: 380,   // 10 rows * 30px + 40px (header) + 40px (filters)
        onRegisterApi: function(gridApi) {

            gridApi.expandable.on.rowExpandedStateChanged($scope, function(row){
                var height = parseInt(uiGridService.removeUnit($scope.jdeNewUserConflictsGridHeight,'px'));
                var changedRowHeight = parseInt(uiGridService.getGridHeight(row.entity.subGridNewUserConflictsGrid, true));

                if (row.isExpanded)
                {
                    height += changedRowHeight;                    
                }
                else
                {
                    height -= changedRowHeight;                    
                }

                $scope.jdeNewUserConflictsGridHeight = height + 'px';
            });
        },
        columnDefs :  [
                { field: 'GridField1', name: 'GridField1', enableFiltering: true }
        ]
    }

I have change setAudioStreamType to setAudioAttributes;

mediaPlayer.setAudioAttributes(AudioAttributes.Builder()
                .setFlags(AudioAttributes.FLAG_AUDIBILITY_ENFORCED)
                .setLegacyStreamType(AudioManager.STREAM_ALARM)
                .setUsage(AudioAttributes.USAGE_ALARM)
                .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                .build());

Addressing the question as updated.

#...part of script without redirection...

{
    #...part of script with redirection...
} > file1 2>file2 # ...and others as appropriate...

#...residue of script without redirection...

The braces '{ ... }' provide a unit of I/O redirection. The braces must appear where a command could appear - simplistically, at the start of a line or after a semi-colon. (Yes, that can be made more precise; if you want to quibble, let me know.)

You are right that you can preserve the original stdout and stderr with the redirections you showed, but it is usually simpler for the people who have to maintain the script later to understand what's going on if you scope the redirected code as shown above.

The relevant sections of the Bash manual are Grouping Commands and I/O Redirection. The relevant sections of the POSIX shell specification are Compound Commands and I/O Redirection. Bash has some extra notations, but is otherwise similar to the POSIX shell specification.

Without a doubt, the simplest method uses an invisible FORM element in HTML specifying the desired REST method. Then the arguments can be inserted into input type=hidden value fields using JavaScript and the form can be submitted from the button click event listener or onclick event using one line of JavaScript. Here is an example that assumes the REST API is in file REST.php:

<body>
<h2>REST-test</h2>
<input type=button onclick="document.getElementById('a').submit();"
    value="Do It">
<form id=a action="REST.php" method=post>
<input type=hidden name="arg" value="val">
</form>
</body>

Note that this example will replace the page with the output from page REST.php. I'm not sure how to modify this if you wish the API to be called with no visible effect on the current page. But it's certainly simple.

I like Tom Faust's answer the best. Here's a C# version of his solution, but simplifying things a bit.

var codecs = ImageCodecInfo.GetImageEncoders(); 
var codecFilter = "Image Files|"; 
foreach (var codec in codecs) 
{
    codecFilter += codec.FilenameExtension + ";"; 
} 
dialog.Filter = codecFilter;

None of these solutions seem to work if you increase the amount of text so it is larger than the width of the parent container, the element to the right still gets moved below the one to the left instead of remaining next to it. To fix this, you can apply this style to the left element:

position: absolute;
width: 50px;

And apply this style to the right element:

margin-left: 50px;

Just make sure that the margin-left for the right element is greater than or equal to the width of the left element. No floating or other attributes are necessary. I would suggest wrapping these elements in a div with the style:

display: inline-block;

Applying this style may not be necessary depending on surrounding elements

Fiddle: http://jsfiddle.net/2b0bqqse/

You can see the text to the right is taller than the element to the left outlined in black. If you remove the absolute positioning and margin and instead use float as others have suggested, the text to the right will drop down below the element to the left

Fiddle: http://jsfiddle.net/qrx78u20/

I figured it out. Basically it's an async issue. You can't just submit and expect to render the subsequent page immediately. You have to wait until the onLoad event for the next page is triggered. My code is below:

var page = new WebPage(), testindex = 0, loadInProgress = false;

page.onConsoleMessage = function(msg) {
  console.log(msg);
};

page.onLoadStarted = function() {
  loadInProgress = true;
  console.log("load started");
};

page.onLoadFinished = function() {
  loadInProgress = false;
  console.log("load finished");
};

var steps = [
  function() {
    //Load Login Page
    page.open("https://website.com/theformpage/");
  },
  function() {
    //Enter Credentials
    page.evaluate(function() {

      var arr = document.getElementsByClassName("login-form");
      var i;

      for (i=0; i < arr.length; i++) { 
        if (arr[i].getAttribute('method') == "POST") {

          arr[i].elements["email"].value="mylogin";
          arr[i].elements["password"].value="mypassword";
          return;
        }
      }
    });
  }, 
  function() {
    //Login
    page.evaluate(function() {
      var arr = document.getElementsByClassName("login-form");
      var i;

      for (i=0; i < arr.length; i++) {
        if (arr[i].getAttribute('method') == "POST") {
          arr[i].submit();
          return;
        }
      }

    });
  }, 
  function() {
    // Output content of page to stdout after form has been submitted
    page.evaluate(function() {
      console.log(document.querySelectorAll('html')[0].outerHTML);
    });
  }
];


interval = setInterval(function() {
  if (!loadInProgress && typeof steps[testindex] == "function") {
    console.log("step " + (testindex + 1));
    steps[testindex]();
    testindex++;
  }
  if (typeof steps[testindex] != "function") {
    console.log("test complete!");
    phantom.exit();
  }
}, 50);

Few Operation relates to Array in Swift

Create Array

var stringArray = ["One", "Two", "Three", "Four"]

Add Object in Array

stringArray = stringArray + ["Five"]

Get Value from Index object

let x = stringArray[1]

Append Object

stringArray.append("At last position")

Insert Object at Index

stringArray.insert("Going", at: 1)

Remove Object

stringArray.remove(at: 3)

Concat Object value

var string = "Concate Two object of Array \(stringArray[1]) + \(stringArray[2])"

Views are not currently supported by Entity Framework Core. See https://github.com/aspnet/EntityFramework/issues/827.

That said, you can trick EF into using a view by mapping your entity to the view as if it were a table. This approach comes with limitations. e.g. you can't use migrations, you need to manually specific a key for EF to use, and some queries may not work correctly. To get around this last part, you can write SQL queries by hand

context.Images.FromSql("SELECT * FROM dbo.ImageView")
