(Neither IN nor ANY is an "operator". A "construct" or "syntax element".)

Logically, quoting the manual:

IN is equivalent to = ANY.

But there are two syntax variants of IN and two variants of ANY. Details:

• How to use ANY instead of IN in a WHERE clause with Rails?

IN taking a set is equivalent to = ANY taking a set, as demonstrated here:

• postgreSQL - in vs any

But the second variant of each is not equivalent to the other. The second variant of the ANY construct takes an array (must be an actual array type), while the second variant of IN takes a comma-separated list of values. This leads to different restrictions in passing values and can also lead to different query plans in special cases:

• Index not used with =any() but used with in
• Pass multiple sets or arrays of values to a function

ANY is more versatile

The ANY construct is far more versatile, as it can be combined with various operators, not just =. Example:

SELECT 'foo' LIKE ANY('{FOO,bar,%oo%}');

For a big number of values, providing a set scales better for each:

• Optimizing a Postgres query with a large IN

Related:

• Can PostgreSQL index array columns?

Inversion / opposite / exclusion

"Find rows where id is in the given array":

SELECT * FROM tbl WHERE id = ANY (ARRAY[1, 2]);

Inversion: "Find rows where id is not in the array":

SELECT * FROM tbl WHERE id <> ALL (ARRAY[1, 2]);
SELECT * FROM tbl WHERE id <> ALL ('{1, 2}');  -- equivalent array literal
SELECT * FROM tbl WHERE NOT (id = ANY ('{1, 2}'));

All three equivalent. The first with array constructor, the other two with array literal. The data type can be derived from context unambiguously. Else, an explicit cast may be required, like '{1,2}'::int[].

Rows with id IS NULL do not pass either of these expressions. To include NULL values additionally:

SELECT * FROM tbl WHERE (id = ANY ('{1, 2}')) IS NOT TRUE;

This came in handy for one of my requirements where I did not want to use CTE and also did not want to go with the inner join.

DECLARE @Ids varchar(50);
SET @Ids = '1,2,3,5,4,6,7,98,234';

SELECT
   cn1,cn2,cn3
FROM tableName
WHERE columnName in (select Value from fn_SplitList(@ids, ','))

Off the top of my head and not guaranteed to be correct: I believe the second will be faster in this case.

1. In the first, the correlated subquery will likely cause the subquery to be run for each row.
2. In the second example, the subquery should only run once, since not correlated.
3. In the second example, the IN will short-circuit as soon as it finds a match.

create sequence serial start 1;

select * from comments c
join (select unnest(ARRAY[1,3,2,4]) as id, nextval('serial') as id_sorter) x
on x.id = c.id
order by x.id_sorter;

drop sequence serial;

[EDIT]

unnest is not yet built-in in 8.3, but you can create one yourself(the beauty of any*):

create function unnest(anyarray) returns setof anyelement
language sql as
$$
    select $1[i] from generate_series(array_lower($1,1),array_upper($1,1)) i;
$$;

that function can work in any type:

select unnest(array['John','Paul','George','Ringo']) as beatle
select unnest(array[1,3,2,4]) as id

There is a way to use this with a hidden div but you have to work abit more with the printElement() function and css.

Css:

#SelectorToPrint{
     display: none;
}

Script:

  $("#SelectorToPrint").printElement({ printBodyOptions:{styleToAdd:'padding:10px;margin:10px;display:block', classNameToAdd:'WhatYouWant'}})

This will override the display: none in the new window you open and the content will be displayed on the print-preview page and the div on you site remains hidden.

In Visual Studio 2019 (Xamarin):

1. Click on the Device Monitor (DDMS) button.

2. Go to the File Explorer tab and click the button with a phone and a right-pointing arrow on top of it.

This working good

$('#id-of-table').on('draw.dt', function() {
    // do action here
});

SELECT DATEADD(day,-30,date) AS before30d 
FROM...

But it is strongly recommended to keep date in datetime column, not varchar.

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN

RETURN QUERY EXECUTE '
WITH v_tb_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;

END     
$$ LANGUAGE plpgsql;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

• You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

• The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work

• I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.

Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)

The query itself seems rather odd, btw. But that's beside the point here.

If you want to implement autocomplete functionality, then Completion Suggester is the most neat solution. The next blog post contains a very clear description how this works.

In two words, it's an in-memory data structure called an FST which contains valid suggestions and is optimised for fast retrieval and memory usage. Essentially, it is just a graph. For instance, and FST containing the words hotel, marriot, mercure, munchen and munich would look like this:

Starting a Session:

Put below code at the top of file.

<?php session_start();?>

Storing a session variable:

<?php $_SESSION['id']=10; ?>

To Check if data stored in session variable:

<?php if(isset($_SESSION['id']) && !empty(isset($_SESSION['id'])))
echo “Session id “.$_SESSION['id'].” exist”;
else
echo “Session not set “;?>

?> detail here http://skillrow.com/sessions-in-php-4/

ucfagls is right, providing you use the plot() command. If not, please give us more detail.

In any case, you can control every axis seperately by using the axis() command and the xaxt/yaxt options in plot(). Using the data of ucfagls, this becomes :

plot(Y ~ X, data=foo,yaxt="n")
axis(2,cex.axis=2)

the option yaxt="n" is necessary to avoid that the plot command plots the y-axis without changing. For the x-axis, this works exactly the same :

plot(Y ~ X, data=foo,xaxt="n")
axis(1,cex.axis=2)

See also the help files ?par and ?axis

Edit : as it is for a barplot, look at the options cex.axis and cex.names :

tN <- table(sample(letters[1:5],100,replace=T,p=c(0.2,0.1,0.3,0.2,0.2)))

op <- par(mfrow=c(1,2))
barplot(tN, col=rainbow(5),cex.axis=0.5) # for the Y-axis
barplot(tN, col=rainbow(5),cex.names=0.5) # for the X-axis
par(op)

You can remove elements from ArrayList using ListIterator,

ListIterator listIterator = List_Of_Array.listIterator();

 /* Use void remove() method of ListIterator to remove an element from List.
     It removes the last element returned by next or previous methods.
 */
listIterator.next();

//remove element returned by last next method
listIterator.remove();//remove element at 1st position
listIterator.next();
listIterator.next();
listIterator.remove();//remove element at 3rd position
listIterator.next();
listIterator.next();
listIterator.remove();//remove element at 5th position

What I do when I mess up my local branch is I just rename my broken branch, and check out/branch the upstream branch again:

git branch -m branch branch-old
git fetch remote
git checkout -b branch remote/branch

Then if you're sure you don't want anything from your old branch, remove it:

git branch -D branch-old

But usually I leave the old branch around locally, just in case I had something in there.

The following creates a generic function, taking an array of any size and of any type by reference:

template<typename T, std::size_t S>
void my_func(T (&arr)[S]) {
   // do stuff
}

play with the code.

The accepted answer gave two locations:

here

C:\Documents and Settings\Administrator\Local Settings\Temp\VWDWebCache

and possibly here

C:\Documents and Settings\Administrator\Local Settings\Application Data\Microsoft\WebsiteCache

Did you try those?

Edited to add

On my Windows Vista machine, it's located in

%Temp%\VWDWebCache

and in

%LocalAppData%\Microsoft\WebsiteCache

From your additional information (regarding team edition) this comes from Clear Client TFS Cache:

Clear Client TFS Cache

Visual Studio and Team Explorer provide a caching mechanism which can get out of sync. If I have multiple instances of a single TFS which can be connected to from a single Visual Studio client, that client can become confused.

To solve it..

For Windows Vista delete contents of this folder

%LocalAppData%\Microsoft\Team Foundation\1.0\Cache

Ubuntu 19.04

All other answers themselves didn't help me. But the following sum up did the job

Create ~/.config/apport/settings with the following content:

[main]
unpackaged=true

(This tells apport to also write core dumps for custom apps)

check: ulimit -c. If it outputs 0, fix it with

ulimit -c unlimited

Just for in case restart apport:

sudo systemctl restart apport

Crash files are now written in /var/crash/. But you cannot use them with gdb. To use them with gdb, use

apport-unpack <location_of_report> <target_directory>

Further information:

• Some answers suggest changing core_pattern. Be aware, that that file might get overwritten by the apport service on restarting.
• Simply stopping apport did not do the job
• The ulimit -c value might get changed automatically while you're trying other answers of the web. Be sure to check it regularly during setting up your core dump creation.

Try using display: inline-block; on the inner div.

#outer {
    width:500px; 
    height:200px; 
    background:#FFCCCC;
    margin:50px auto 0 auto;
    display:block;
}
#inner {
    background:#FFCC33;
    margin:50px 50px 50px 50px;
    padding:10px;
    display:inline-block;
}

In case you expect more than one maximum this will work:

_.maxBy(Object.entries(_.groupBy(x, y => y.length)), y => parseInt(y[0]))[1]

It uses lodash and returns an array.

You can use a rewrite rule that uses ^$ to represent the root and rewrite that to your /store directory, like this:

RewriteEngine On
RewriteRule ^$ /store [L]

In Python, to represent the absence of a value, you can use the None value (types.NoneType.None) for objects and "" (or len() == 0) for strings. Therefore:

if yourObject is None:  # if yourObject == None:
    ...

if yourString == "":  # if yourString.len() == 0:
    ...

Regarding the difference between "==" and "is", testing for object identity using "==" should be sufficient. However, since the operation "is" is defined as the object identity operation, it is probably more correct to use it, rather than "==". Not sure if there is even a speed difference.

Anyway, you can have a look at:

• Python Built-in Constants doc page.
• Python Truth Value Testing doc page.

If this is the current url use window.location.pathname otherwise use this regular expression:

var reg = /.+?\:\/\/.+?(\/.+?)(?:#|\?|$)/;
var pathname = reg.exec( 'http://www.somedomain.com/account/search?filter=a#top' )[1];

We can define user defined comparator: .The code below can be helpful for you.

Code Snippet :

#include<bits/stdc++.h>
using namespace std;

struct man
{
  string name;
  int priority; 
};

class comparator
{
 public:
   bool operator()(const man& a, const man& b)
   {
        return a.priority<b.priority;
   }
};

int main()
{
   man arr[5];
   priority_queue<man, vector<man>, comparator> pq;

   for(int i=0; i<3; i++)
   {
     cin>>arr[i].name>>arr[i].priority;
     pq.push(arr[i]);
   }

   while (!pq.empty())
   {
     cout<<pq.top().name<<" "<<pq.top().priority;
     pq.pop();
     cout<<endl;
   }
   return 0;
}

input :

batman 2
goku 9
mario 4

Output

goku 9
mario 4
batman 2

If you want to check through a server.php or whatever, you want to call it with the following:

<?php
    phpinfo(INFO_VARIABLES);
?>

or

<?php
    header("Content-type: text/plain");

    print_r($_SERVER);
?>

Then access it with all the valid URLs for your site and check out the difference.

I have put together all of the pieces of this solution using the Newtonsoft.Json library. It fixes the enum issue and also makes the error handling much better, and it works in IIS hosted services. It's quite a lot of code, so you can find it on GitHub here: https://github.com/jongrant/wcfjsonserializer/blob/master/NewtonsoftJsonFormatter.cs

You have to add some entries to your Web.config to get it to work, you can see an example file here: https://github.com/jongrant/wcfjsonserializer/blob/master/Web.config

xargs consumes newlines as well (but adds a final trailing newline):

xargs < file.txt | tr -d ' '

Or can say whats fields not will expose with:

Gson gson = gsonBuilder.excludeFieldsWithModifiers(Modifier.TRANSIENT).create();

on your class on attribute:

private **transient** boolean nameAttribute;

Yes, you can. But if you have non-unique entries on your table, it will fail. Here is the how to add unique constraint on your table. If you're using PostgreSQL 9.x you can follow below instruction.

CREATE UNIQUE INDEX constraint_name ON table_name (columns);

It complains because it needs to use ssh instead of https but your git is still configured with https. so basically as others mentioned previously you need to either enable prompts or to configure git to use ssh instead of https. a simple way to do this by running the following:

git config --global --add url."[email protected]:".insteadOf "https://github.com/"

or if you already use ssh with git in your machine, you can safely edit ~/.gitconfig and add the following line at the very bottom

Note: This covers all SVC, source version control, that depends on what you exactly use, github, gitlab, bitbucket)

# Enforce SSH
[url "ssh://[email protected]/"]
  insteadOf = https://github.com/
[url "ssh://[email protected]/"]
        insteadOf = https://gitlab.com/
[url "ssh://[email protected]/"]
  insteadOf = https://bitbucket.org/

• If you want to keep password pompts disabled, you need to cache password. For more information on how to cache your github password on mac, windows or linux, please visit this page.

• For more information on how to add ssh to your github account, please visit this page.

Also, more importantly, if this is a private repository for a company or for your self, you may need to skip using proxy or checksum database for such repos to avoid exposing them publicly.

To do this, you need to set GOPRIVATE environment variable that controls which modules the go command considers to be private (not available publicly) and should therefore NOT use the proxy or checksum database.

The variable is a comma-separated list of patterns (same syntax of Go's path.Match) of module path prefixes. For example,

export GOPRIVATE=*.corp.example.com,github.com/mycompany/*

Or

go env -w GOPRIVATE=github.com/mycompany/*

• For more information about go 13 modules and new enhancements, please check out Go 1.13 Modules Release notes.

One last thing not to forget to mention, you can still configure go get to authenticate and fetch over https, all you need to do is to add the following line to $HOME/.netrc

I believe that although javascript is an option here, you have a smoother animation through forcing hardware accelerate with CSS3. You can achieve this by setting the following CSS3 properties on the moving div:

div.hardware-accelarate {
     -webkit-transform: translate3d(0,0,0);
        -moz-transform: translate3d(0,0,0);
         -ms-transform: translate3d(0,0,0);
          -o-transform: translate3d(0,0,0);
             transform: translate3d(0,0,0);
}

I've made a plunkr setup for ya'll to test and tweak...

Given a string, with a complete python path to a function, this is how I went about getting the result of said function:

import importlib
function_string = 'mypackage.mymodule.myfunc'
mod_name, func_name = function_string.rsplit('.',1)
mod = importlib.import_module(mod_name)
func = getattr(mod, func_name)
result = func()

Use localhost instead of your IP address.

e.g,

$myServer = "localhost";

And also double check your mysql username and password.

SOAP (Simple Object Access Protocol) is the communication protocol in the web service scenario.

One benefit of SOAP is that it allowas RPC to execute through a firewall. But to pass through a firewall, you will probably want to use 80. it uses port no.8084 To the firewall, a SOAP conversation on 80 looks like a POST to a web page. However, there are extensions in SOAP which are specifically aimed at the firewall. In the future, it may be that firewalls will be configured to filter SOAP messages. But as of today, most firewalls are SOAP ignorant.

so exclusively open SOAP Port in Firewalls

Your firewall does not allow any new connection to share information without your consent. ONLY thing to do is give your consent to your firewall.

1. Go to Firewall settings in Control Panel

2. Click on Advanced Settings

3. Click on Inbound Rules and Add a new rule.

4. Choose 'Type Of Rule' to Port.

5. Allow this for All Programs.

6. Allow this rule to be applied on all Profiles i.e. Domain, Private, Public.

7. Give this rule any name.

That's it. Now another PC and mobiles connected on the same network can access the local sites. Lets Start Development.

You need to use the alias directive for location /static:

server {

  index index.html;
  server_name test.example.com;

  root /web/test.example.com/www;

  location /static/ {
    alias /web/test.example.com/static/;
  }

}

The nginx wiki explains the difference between root and alias better than I can:

Note that it may look similar to the root directive at first sight, but the document root doesn't change, just the file system path used for the request. The location part of the request is dropped in the request Nginx issues.

Note that root and alias handle trailing slashes differently.

Or just use Apache CXF's wsdl2java to generate objects you can use.

It is included in the binary package you can download from their website. You can simply run a command like this:

$ ./wsdl2java -p com.mynamespace.for.the.api.objects -autoNameResolution http://www.someurl.com/DefaultWebService?wsdl

It uses the wsdl to generate objects, which you can use like this (object names are also grabbed from the wsdl, so yours will be different a little):

DefaultWebService defaultWebService = new DefaultWebService();
String res = defaultWebService.getDefaultWebServiceHttpSoap11Endpoint().login("webservice","dadsadasdasd");
System.out.println(res);

There is even a Maven plug-in which generates the sources: https://cxf.apache.org/docs/maven-cxf-codegen-plugin-wsdl-to-java.html

Note: If you generate sources using CXF and IDEA, you might want to look at this: https://stackoverflow.com/a/46812593/840315

For future people struggling with a similar problem, the situation is that the compiler simply cannot find the type you are using (even if your Intelisense can find it).

This can be caused in many ways:

• You forgot to #include the header that defines it.
• Your inclusion guards (#ifndef BLAH_H) are defective (your #ifndef BLAH_H doesn't match your #define BALH_H due to a typo or copy+paste mistake).
• Your inclusion guards are accidentally used twice (two separate files both using #define MYHEADER_H, even if they are in separate directories)
• You forgot that you are using a template (eg. new Vector() should be new Vector<int>())
• The compiler is thinking you meant one scope when really you meant another (For example, if you have NamespaceA::NamespaceB, AND a <global scope>::NamespaceB, if you are already within NamespaceA, it'll look in NamespaceA::NamespaceB and not bother checking <global scope>::NamespaceB) unless you explicitly access it.
• You have a name clash (two entities with the same name, such as a class and an enum member).

To explicitly access something in the global namespace, prefix it with ::, as if the global namespace is a namespace with no name (e.g. ::MyType or ::MyNamespace::MyType).

We were seeing this same issue in one of our old projects that was targeting Framework 4.5.2. I tried several scenarios including all of the ones listed above: target 4.6.1, add System.ValueTuple package, delete bin, obj, and .vs folders. No dice. Repeat the same process for 4.7.2. Then tried removing the System.ValueTuple package since I was targeting 4.7.2 as one commenter suggested. Still nothing. Checked csproj file reference path. Looks right. Even dropped back down to 4.5.2 and installing the package again. All this with several VS restarts and deleting the same folders several times. Literally nothing worked.

I had to refactor to use a struct instead. I hope others don't continue to run into this issue in the future but thought this might be helpful if you end up as stumped up as we were.

you can try this.

data_you_need=pd.DataFrame()
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    data_you_need=data_you_need.append(data,ignore_index=True)

A variant exists in which you can specify a prefix and suffix too.

See here for an implementation using foldLeft, which is much more verbose, but perhaps worth looking at for education's sake.

It was requested that I add this functionality to the stackoverflow R package. Given that it is a tinyverse package (and can't depend on third party packages), here is what I came up with:

#' Bulk import data files 
#' 
#' Read in each file at a path and then unnest them. Defaults to csv format.
#' 
#' @param path        a character vector of full path names
#' @param pattern     an optional \link[=regex]{regular expression}. Only file names which match the regular expression will be returned.
#' @param reader      a function that can read data from a file name.
#' @param ...         optional arguments to pass to the reader function (eg \code{stringsAsFactors}).
#' @param reducer     a function to unnest the individual data files. Use I to retain the nested structure. 
#' @param recursive     logical. Should the listing recurse into directories?
#'  
#' @author Neal Fultz
#' @references \url{https://stackoverflow.com/questions/11433432/how-to-import-multiple-csv-files-at-once}
#' 
#' @importFrom utils read.csv
#' @export
read.directory <- function(path='.', pattern=NULL, reader=read.csv, ..., 
                           reducer=function(dfs) do.call(rbind.data.frame, dfs), recursive=FALSE) {
  files <- list.files(path, pattern, full.names = TRUE, recursive = recursive)

  reducer(lapply(files, reader, ...))
}

By parameterizing the reader and reducer function, people can use data.table or dplyr if they so choose, or just use the base R functions that are fine for smaller data sets.

Here's a combination of the solutions I've found (sample project here, if you want to also check auto-fill):

manifest

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

        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        tryGetCurrentUserPhoneNumber(this)
        googleApiClient = GoogleApiClient.Builder(this).addApi(Auth.CREDENTIALS_API).build()
        if (phoneNumber.isEmpty()) {
            val hintRequest = HintRequest.Builder().setPhoneNumberIdentifierSupported(true).build()
            val intent = Auth.CredentialsApi.getHintPickerIntent(googleApiClient, hintRequest)
            try {
                startIntentSenderForResult(intent.intentSender, REQUEST_PHONE_NUMBER, null, 0, 0, 0);
            } catch (e: IntentSender.SendIntentException) {
                Toast.makeText(this, "failed to show phone picker", Toast.LENGTH_SHORT).show()
            }
        } else

np.array_equal([1, 2], [1, 2, 3])
False
np.array_equal([1, 2], [1, 4])
False

if you install git with git bash, you get SCP available on windows.

1. for second point, get a full path to pdf file into some java variable. e.g. http://www.domain.com/files/filename.pdf

e.g. you're using php and $filepath contains pdf file path.

so you can write javascript like to to emulate download dialog box.

<script language="javascript">
    window.location.href = '<?php echo $filepath; ?>';
</script

Above code sends browser to pdf file by its url "http://www.domain.com/files/filename.pdf". So at last, browser will show download dialog box to where to save this file on your machine.

You have getSelectedXXX methods from the AdapterView class from which the Spinner derives:

getSelectedItem()

getSelectedItemPosition()

getSelectedItemId()

If the given solutions does not work, create a new project with 'KOTLIN' as the language even if your work is on java. Then replace the 'main' folder of the new project with the 'main' folder of the old.

Maybe you need "sys." before:

select * from sys.registry$history;

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

If you are using the Eclipse IDE, check your Debug/Run configuration. At Classpath tab, select the runner project and click Edit button. Only include exported entries must be checked.

Use the config method to change the value of the label:

top = Tk()

l = Label(top)
l.pack()

l.config(text = "Hello World", width = "50")

Look at this link

Then write your test case as

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"/applicationContext.xml"})
public class MyLauncherTest{

@Resource
private MyLauncher myLauncher ;

   @Test
   public void someTest() {
       //test code
   }
}

                string BaseWindow = driver.CurrentWindowHandle;
                ReadOnlyCollection<string> handles = driver.WindowHandles;
                foreach (string handle in handles)
                {
                    if (handle != BaseWindow)
                    {
                        string title = driver.SwitchTo().Window(handle).Title;
                        Thread.Sleep(3000);
                        driver.SwitchTo().Window(handle).Title.Equals(title);
                        Thread.Sleep(3000);
                    }
                }

pass date to moment like this it will compare and give result. if you dont want format remove it

moment(Date1).format("YYYY-MM-DD") > moment(Date2).format("YYYY-MM-DD")

AWS_S3_REGION_NAME = "ap-south-1"

AWS_S3_SIGNATURE_VERSION = "s3v4"

this also saved my time after surfing for 24Hours..

First change your package.json file,

"scripts":
    { 
        "start": "node ./bin/www",
        "start-dev": "nodemon ./app.js"
    },

After that, execute command

npm run start-dev

Also, you can check if it's defined while in a string via interpolation, if you code:

puts "Is array1 defined and what type is it? #{defined?(@array1)}"

The system will tell you the type if it is defined. If it is not defined it will just return a warning saying the variable is not initialized.

Hope this helps! :)

Assuming you only have the list of items and a list of true/required indices, this should be the fastest:

property_asel = [ property_a[index] for index in good_indices ]

This means the property selection will only do as many rounds as there are true/required indices. If you have a lot of property lists that follow the rules of a single tags (true/false) list you can create an indices list using the same list comprehension principles:

good_indices = [ index for index, item in enumerate(good_objects) if item ]

This iterates through each item in good_objects (while remembering its index with enumerate) and returns only the indices where the item is true.

For anyone not getting the list comprehension, here is an English prose version with the code highlighted in bold:

list the index for every group of index, item that exists in an enumeration of good objects, if (where) the item is True

In my case, the static content was already being served:

app.use('/*', express.static(path.join(__dirname, '../pub/index.html')));

...and everything in the app seemed to rely on that in some way. (path dep is require('path'))

So, a) yes, it can be a file; and b) you can make a redirect!

app.get('/', function (req, res) { res.redirect('/index.html') });

Now anyone hitting / gets /index.html which is served statically from ../pub/index.html.

Hope this helps someone else.

I would opt for NOT EXISTS in this case.

SELECT D1.ShortCode
FROM Domain1 D1
WHERE NOT EXISTS
    (SELECT 'X'
     FROM Domain2 D2
     WHERE D2.ShortCode = D1.ShortCode
    )

You can use the built in cache attribute to prevent caching.

For .net Framework: [OutputCache(NoStore = true, Duration = 0)]

For .net Core: [ResponseCache(NoStore = true, Duration = 0)]

Be aware that it is impossible to force the browser to disable caching. The best you can do is provide suggestions that most browsers will honor, usually in the form of headers or meta tags. This decorator attribute will disable server caching and also add this header: Cache-Control: public, no-store, max-age=0. It does not add meta tags. If desired, those can be added manually in the view.

Additionally, JQuery and other client frameworks will attempt to trick the browser into not using it's cached version of a resource by adding stuff to the url, like a timestamp or GUID. This is effective in making the browser ask for the resource again but doesn't really prevent caching.

On a final note. You should be aware that resources can also be cached in between the server and client. ISP's, proxies, and other network devices also cache resources and they often use internal rules without looking at the actual resource. There isn't much you can do about these. The good news is that they typically cache for shorter time frames, like seconds or minutes.

Depending on what you want to accomplish, you might want to try out KeyValuePair.

The fact that you cannot change the key of an entry can of course be rectified by simply replacing the entire entry by a new instance of KeyValuePair.

Get Shared Preferences Color Code in String then Convert to integer and add layout-background color:

    sharedPreferences = getSharedPreferences(mypref, Context.MODE_PRIVATE);
    String sw=sharedPreferences.getString(name, "");
    relativeLayout.setBackgroundColor(Color.parseColor(sw));

In June 2016 Google announced that they would stop supporting keyless usage, meaning any request that doesn’t include an API key or Client ID. This will go into effect on June 11 2018, and keyless access will no longer be supported

Was facing the same issue, used this one

Console.log(Date.parse("Jun 13, 2018 10:50:39 GMT+1"));

It will return milliseconds to which u can check have +100 timzone intialize British time Hope it helps!!

If you don't have access to the classes to change the properties, or don't want to always use the same rename property, renaming can also be done by creating a custom resolver.

For example, if you have a class called MyCustomObject, that has a property called LongPropertyName, you can use a custom resolver like this…

public class CustomDataContractResolver : DefaultContractResolver
{
  public static readonly CustomDataContractResolver Instance = new CustomDataContractResolver ();

  protected override JsonProperty CreateProperty(MemberInfo member, MemberSerialization memberSerialization)
  {
    var property = base.CreateProperty(member, memberSerialization);
    if (property.DeclaringType == typeof(MyCustomObject))
    {
      if (property.PropertyName.Equals("LongPropertyName", StringComparison.OrdinalIgnoreCase))
      {
        property.PropertyName = "Short";
      }
    }
    return property;
  }
}

Then call for serialization and supply the resolver:

 var result = JsonConvert.SerializeObject(myCustomObjectInstance,
                new JsonSerializerSettings { ContractResolver = CustomDataContractResolver.Instance });

And the result will be shortened to {"Short":"prop value"} instead of {"LongPropertyName":"prop value"}

More info on custom resolvers here

I have had success with:

require 'time'
t = Time.parse(some_string)

You can use Java 8 Stream API.

Method distinct is an intermediate operation that filters the stream and allows only distinct values (by default using the Object::equals method) to pass to the next operation.
I wrote an example below for your case,

// Create the list with duplicates.
List<String> listAll = Arrays.asList("CO2", "CH4", "SO2", "CO2", "CH4", "SO2", "CO2", "CH4", "SO2");

// Create a list with the distinct elements using stream.
List<String> listDistinct = listAll.stream().distinct().collect(Collectors.toList());

// Display them to terminal using stream::collect with a build in Collector.
String collectAll = listAll.stream().collect(Collectors.joining(", "));
System.out.println(collectAll); //=> CO2, CH4, SO2, CO2, CH4 etc..
String collectDistinct = listDistinct.stream().collect(Collectors.joining(", "));
System.out.println(collectDistinct); //=> CO2, CH4, SO2

You can use the following code form Java

new String(Files.readAllBytes(Paths.get(getClass().getResource("example.txt").toURI())));

In Java Brute force algorithm works faster than piggy backed merge sort algorithm this is because of run time optimization done by Java Dynamic compiler.

For Brute force loop rolling optimization will result in much better results.

@Future-searchers: you can use aspell to do the dictionary checks, it has bindings in ruby and python. It would make your job much simpler.

Have you included the System.Web assembly in the application?

using System.Web;

If not, try specifying the System.Web namespace, for example:

 System.Web.HttpContext.Current

Using the Drag and Drop method

1. From the windows search bar type in cmd to pull up the windows bar operation.
2. When the command line option is shown, right click it and select Open File Location.
3. The file explorer opens and the shortcut link is highlighted in the folder. If it is not highlighted, then select it.
4. Hold down the Control key and using the mouse drag the shortcut to the desktop. If you don't see Copy to Desktop while dragging and before dropping, then push down and hold the Control key until you see the message.
5. Drop the link on the desktop.
6. Change properties as needed.

Hiya demo http://jsfiddle.net/LYTbc/

this is a reference to the DOM element, so you can wrap it directly.

attr api: http://api.jquery.com/attr/

The .attr() method gets the attribute value for only the first element in the matched set.

have a nice one, cheers!

code

$(document).ready(function () {
    $(".inputs").click(function () {
         alert(this.id);

        alert(" or " + $(this).attr("id"));

    });

});?

I have this function...

var escapeURIparam = function(url) {
    if (encodeURIComponent) url = encodeURIComponent(url);
    else if (encodeURI) url = encodeURI(url);
    else url = escape(url);
    url = url.replace(/\+/g, '%2B'); // Force the replacement of "+"
    return url;
};

I arrived at this peculiar, hard-to-debug error through a different route. My trouble ended up being that I was using a pattern rule in a build step when the target and the dependency were located in distinct directories. Something like this:

foo/apple.o: bar/apple.c $(FOODEPS)

%.o: %.c
    $(CC) $< -o $@

I had several dependencies set up this way, and was trying to use one pattern recipe for them all. Clearly, a single substitution for "%" isn't going to work here. I made explicit rules for each dependency, and I found myself back among the puppies and unicorns!

foo/apple.o: bar/apple.c $(FOODEPS)
    $(CC) $< -o $@

Hope this helps someone!

The C# / .NET engine we use for licence key generation is now maintained as open source:

https://github.com/appsoftware/.NET-Licence-Key-Generator.

It's based on a "Partial Key Verification" system which means only a subset of the key that you use to generate the key has to be compiled into your distributable. You create the keys your self, so the licence implementation is unique to your software.

As stated above, if your code can be decompiled, it's relatively easy to circumvent most licencing systems.

Try this:

select nextval('my_seq_name');  // Returns next value

If this return 1 (or whatever is the start_value for your sequence), then reset the sequence back to the original value, passing the false flag:

select setval('my_seq_name', 1, false);

Otherwise,

select setval('my_seq_name', nextValue - 1, true);

This will restore the sequence value to the original state and "setval" will return with the sequence value you are looking for.

Add this class css to your style sheet

}

set width to the width of your image. and use this html for image

<div class="border_gradient">
        <img src="image.png" />
</div>

though it may not give the same exact border, it will some gradient looks on the border.

In the specific case in your example, I'd use the STL algorithms to accomplish this.

#include <numeric> 

sum = std::accumulate( polygon.begin(), polygon.end(), 0 );

For a more general, but still fairly simple case, I'd go with:

#include <boost/lambda/lambda.hpp>
#include <boost/lambda/bind.hpp>

using namespace boost::lambda;
std::for_each( polygon.begin(), polygon.end(), sum += _1 );

You can do it via the constructor of your class:

public class foo {
  public foo(){
    Bar = "bar";
  }
  public string Bar {get;set;}
}

If you've got another constructor (ie, one that takes paramters) or a bunch of constructors you can always have this (called constructor chaining):

public class foo {
  private foo(){
    Bar = "bar";
    Baz = "baz";
  }
  public foo(int something) : this(){
    //do specialized initialization here
    Baz = string.Format("{0}Baz", something);
  }
  public string Bar {get; set;}
  public string Baz {get; set;}
}

If you always chain a call to the default constructor you can have all default property initialization set there. When chaining, the chained constructor will be called before the calling constructor so that your more specialized constructors will be able to set different defaults as applicable.

I wasn't satisfied with the marked and upvoted answers, so here is a simple and general solution for transforming JSON-style nested datastructures (made of dicts and lists) into hierachies of plain objects:

# tested in: Python 3.8
from collections import abc
from typings import Any, Iterable, Mapping, Union

class DataObject:
    def __repr__(self):
        return str({k: v for k, v in vars(self).items()})

def data_to_object(data: Union[Mapping[str, Any], Iterable]) -> object:
    """
    Example
    -------
    >>> data = {
    ...     "name": "Bob Howard",
    ...     "positions": [{"department": "ER", "manager_id": 13}],
    ... }
    ... data_to_object(data).positions[0].manager_id
    13
    """
    if isinstance(data, abc.Mapping):
        r = DataObject()
        for k, v in data.items():
            if type(v) is dict or type(v) is list:
                setattr(r, k, data_to_object(v))
            else:
                setattr(r, k, v)
        return r
    elif isinstance(data, abc.Iterable):
        return [data_to_object(e) for e in data]
    else:
        return data

Simplest way I found:

cd my_dir && tar -czvf ../my_dir.tar.gz *

window.addEventListener('scroll', function (e) {
        var nav = document.getElementById('nav');
        if (document.documentElement.scrollTop || document.body.scrollTop > window.innerHeight) {
                nav.classList.add('nav-colored');
                nav.classList.remove('nav-transparent');
            } else {
                nav.classList.add('nav-transparent');
                nav.classList.remove('nav-colored');
            }
    });

best approach to use event listener. especially for Firefox browser, check this doc Scroll-linked effects and Firefox is no longer support document.body.scrollTop and alternative to use document.documentElement.scrollTop. This is completes the answer from Yahya Essam

The following code will load an image from a file image.png and will display it as grayscale.

import numpy as np
import matplotlib.pyplot as plt
from PIL import Image

fname = 'image.png'
image = Image.open(fname).convert("L")
arr = np.asarray(image)
plt.imshow(arr, cmap='gray', vmin=0, vmax=255)
plt.show()

If you want to display the inverse grayscale, switch the cmap to cmap='gray_r'.

Like this:

<c:forEach var="entry" items="${myMap}">
  Key: <c:out value="${entry.key}"/>
  Value: <c:out value="${entry.value}"/>
</c:forEach>

You asked: 'Are there any applicable differences between dict.items() and dict.iteritems()'

This may help (for Python 2.x):

>>> d={1:'one',2:'two',3:'three'}
>>> type(d.items())
<type 'list'>
>>> type(d.iteritems())
<type 'dictionary-itemiterator'>

You can see that d.items() returns a list of tuples of the key, value pairs and d.iteritems() returns a dictionary-itemiterator.

As a list, d.items() is slice-able:

>>> l1=d.items()[0]
>>> l1
(1, 'one')   # an unordered value!

But would not have an __iter__ method:

>>> next(d.items())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list object is not an iterator

As an iterator, d.iteritems() is not slice-able:

>>> i1=d.iteritems()[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'dictionary-itemiterator' object is not subscriptable

But does have __iter__:

>>> next(d.iteritems())
(1, 'one')               # an unordered value!

So the items themselves are same -- the container delivering the items are different. One is a list, the other an iterator (depending on the Python version...)

So the applicable differences between dict.items() and dict.iteritems() are the same as the applicable differences between a list and an iterator.

It's simply a matter of scaling the image width and height up by the correct ratio. Not all images formats support a DPI metatag, and when they do, all they're telling your graphics software to do is divide the image by the ratio supplied.

For example, if you export a 300dpi image from Photoshop to a JPEG, the image will appear to be very large when viewed in your picture viewing software. This is because the DPI information isn't supported in JPEG and is discarded when saved. This means your picture viewer doesn't know what ratio to divide the image by and instead displays the image at at 1:1 ratio.

To get the ratio you need to scale the image by, see the code below. Just remember, this will stretch the image, just like it would in Photoshop. You're essentially quadrupling the size of the image so it's going to stretch and may produce artifacts.

Pseudo code

ratio = 300.0 / 72.0   // 4.167
image.width * ratio
image.height * ratio

Nothing mentioned above worked for me. However, I fixed it myself.

Solution:

If you've any other files except activity_main.xml / main.xml inside app_name/res/layout remove it and try clean and build.

Note:

The unwanted files or (rather used later) files inside app_name/res/layout would be *.out.xml. Remove the same.

Guessing that what you want to do, is call Files.lines(...) on a resource that comes from the classpath - possibly from within a jar.

Since Oracle convoluted the notion of when a Path is a Path by not making getResource return a usable path if it resides in a jar file, what you need to do is something like this:

Stream<String> stream = new BufferedReader(new InputStreamReader(ClassLoader.getSystemResourceAsStream("/filename.txt"))).lines();

In CentOS/RedHat (assuming you installed the jenkins package)

vim /etc/sysconfig/jenkins

....
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="8080"

change it to any port you want.

I fell into this dilemma once, and researched quite a bit on google for opinions. What I found was that indeed many see saving images to disk better for larger images, while mySQL allows for easier access, specially from languages like PHP.

I found a similar question

MySQL BLOB vs File for Storing Small PNG Images?

My final verdict was that for things such as a profile picture, just a small square image that needs to be there per user, mySQL would be better than storing a bunch of thumbs in the hdd, while for photo albums and things like that, folders/image files are better.

Hope it helps

From the documentation on expandtab:

To insert a real tab when expandtab is on, use CTRL-V<Tab>. See also :retab and ins-expandtab.
This option is reset when the paste option is set and restored when the paste option is reset.

So if you have a mapping for toggling the paste option, e.g.

set pastetoggle=<F2>

you could also do <F2>Tab<F2>.

This is another way to specify the range of the bit-vector.

x +: N, The start position of the vector is given by x and you count up from x by N.

There is also

x -: N, in this case the start position is x and you count down from x by N.

N is a constant and x is an expression that can contain iterators.

It has a couple of benefits -

1. It makes the code more readable.

2. You can specify an iterator when referencing bit-slices without getting a "cannot have a non-constant value" error.

psql --pset=format=FORMAT

Great for executing queries from command line, e.g.

psql --pset=format=unaligned -c "select bandanavalue from bandana where bandanakey = 'atlassian.confluence.settings';"

In my case has helped to exclude javax.transaction.jta dependency from hibernate:

<dependency>

  <exclusions>
    <exclusion>
      <groupId>javax.transaction</groupId>
      <artifactId>jta</artifactId>
    </exclusion>
  </exclusions>
</dependency>

You can force checkout your branch, if you do not want to commit your local changes.

git checkout -f branch_name

Because tuple(3, 4) is not the correct syntax to create a tuple. The correct syntax is -

tuple([3, 4])

or

(3, 4)

You can see it from here - https://docs.python.org/2/library/functions.html#tuple

What about paint.getTextBounds() (object method)

Main culprit for this error is logic which determines encoding when converting Stream or byte[] array to .NET string.

Using StreamReader created with 2nd constructor parameter detectEncodingFromByteOrderMarks set to true, will determine proper encoding and create string which does not break XmlDocument.LoadXml method.

public string GetXmlString(string url)
{
    using var stream = GetResponseStream(url);
    using var reader = new StreamReader(stream, true);
    return reader.ReadToEnd(); // no exception on `LoadXml`
}

Common mistake would be to just blindly use UTF8 encoding on the stream or byte[]. Code bellow would produce string that looks valid when inspected in Visual Studio debugger, or copy-pasted somewhere, but it will produce the exception when used with Load or LoadXml if file is encoded differently then UTF8 without BOM.

public string GetXmlString(string url)
{
    byte[] bytes = GetResponseByteArray(url);
    return System.Text.Encoding.UTF8.GetString(bytes); // potentially exception on `LoadXml`
}

I am posting this answer because none of the other answers given here actually worked for me. I could not use COPY from within Postgres, because I did not have the correct permissions. So I chose "Export grid rows" and saved the output as UTF-8.

The psql version given by @Brian also did not work for me, for a different reason. The reason it did not work is that apparently the Windows command prompt (I was using Windows) was meddling around with the encoding on its own. I kept getting this error:

ERROR: character with byte sequence 0x81 in encoding "WIN1252" has no equivalent in encoding "UTF8"

The solution I ended up using was to write a short JDBC script (Java) which read the CSV file and issued insert statements directly into my Postgres table. This worked, but the command prompt also would have worked had it not been altering the encoding.

use this URL : "https://twitter.com/(userName)/profile_image?size=original"

If you are using TWitter SDK you can get the user name when logged in, with TWTRAPIClient, using TWTRAuthSession.

This is the code snipe for iOS:

if let twitterId = session.userID{
   let twitterClient = TWTRAPIClient(userID: twitterId)
   twitterClient.loadUser(withID: twitterId) {(user, error) in
       if let userName = user?.screenName{
          let url = "https://twitter.com/\(userName)/profile_image?size=original")
       }
   }
}

No it doesn't need to be constant, the reason why his code above is wrong is because he needs to include a variable name before the declaration.

int row = 8;
int col= 8;
int x[row][col];

In Xcode that will compile and run without any issues, in M$ C++ compiler in .NET it won't compile, it will complain that you cannot use a non const literal to initialize array, the size needs to be known at compile time

If you are using Maven you may have both src/{main,test}/resources/META-INF/persistence.xml. This is a common setup: test your JPA code with h2 or Derby and deploy it with PostgreSQL or some other full DBMS. If you're using this pattern, do make sure the two files have different unit names, else some versions of the Persistence class will try to load BOTH (because of course your test-time CLASSPATH includes both classes and test-classes); this will cause conflicting definitions of the persistence unit, resulting in the dreaded annoying message that we all hate so much!

Worse: this may "work" with some older versions of e.g., Hibernate, but fail with current versions. Worth getting it right anyway...

try to do this in the behind code

   public diagboxclass()
   {
         List<object> list = new List<object>();
         list = GetObjectList();
         Imported.ItemsSource = null;
         Imported.ItemsSource = list;
   }

Also be sure your list is effectively populated and as mentioned by Blindmeis, never use words that already are given a function in c#.

You can try something like this

r = requests.get(ENDPOINT, params=params, headers={'Authorization': 'Basic %s' %  API_KEY})

Copy-paste the following into your current terminal:

gsettings set org.gnome.desktop.default-applications.terminal exec /usr/bin/terminator
gsettings set org.gnome.desktop.default-applications.terminal exec-arg "-x"

This modifies the dconf to make terminator the default program. You could also use dconf-editor (a GUI-based tool) to make changes to the dconf, as another answer has suggested. If you would like to learn and understand more about this topic, this may help you.

if (substr_count($this->content,'<p>') == 1)
{
  $this->content = preg_replace('/<\/?p>/i', '', $this->content);
}

I would recommend using the LINQ extension methods. You can easily do it with one line of code like so:

list2 = list2.Except(list1).ToList();

This is assuming of course the objects in list1 that you are removing from list2 are the same instance.

A little bit more expanded than list comprehension but likewise useful:

def str_list_to_int_list(str_list):
    n = 0
    while n < len(str_list):
        str_list[n] = int(str_list[n])
        n += 1
    return(str_list)

e.g.

>>> results = ["1", "2", "3"]
>>> str_list_to_int_list(results)
[1, 2, 3]

Also:

def str_list_to_int_list(str_list):
    int_list = [int(n) for n in str_list]
    return int_list

LastLogon is the last time that the user logged into whichever domain controller you happen to have been load balanced to at the moment that you ran the GET-ADUser cmdlet, and is not replicated across the domain. You really should use LastLogonTimestamp if you want the time the last user logged in to any domain controller in your domain.

The error tells that the system cannot find the truststore in the path provided with the parameter javax.net.ssl.trustStore.

Under Windows I copied the cacerts file from jre/lib/security into the Eclipse install directory (same place as the eclipse.ini file) and added the following settings in eclipse.ini:

-Djavax.net.ssl.trustStore=cacerts
-Djavax.net.ssl.trustStorePassword=changeit
-Djavax.net.ssl.trustStoreType=JKS

I had some troubles with the path to the cacerts (the %java_home% environment variable is somehow overwritten), so I used this trivial solution.

The idea is to provide a valid path to the truststore file - ideally it would be to use a relative one. You may also use an absolute path.

To make sure the store type is JKS, you would run the following command:

keytool -list -keystore cacerts

Keystore type: JKS
Keystore provider: SUN

Note: because certificates have expiration dates, or can become invalid for other reasons, do check from time to time if the certificates in cacerts are still valid. You would usually find the valid versions of the certificates in the latest builds of jdk.

Here is a good breakdown of the pros and cons:

So, it appears that constants should be used when it is very unlikely that the value will ever change, or if no external apps/libs will be using the constant. Static readonly fields should be used when run-time calculation is required, or if external consumers are a factor.

Even the last example given on http://www.howtocreate.co.uk/tutorials/javascript/browserwindow is not working on Quirks mode. Easier to find than I thought, this seems to be the solution(extracted from latest jquery code):

Math.max(
    document.documentElement["clientWidth"],
    document.body["scrollWidth"],
    document.documentElement["scrollWidth"],
    document.body["offsetWidth"],
    document.documentElement["offsetWidth"]
);

just replace Width for "Height" to get Height.

The major cornerstone knowledge must be the quoted one,

When an object reference is passed to a method, the reference itself is passed by use of call-by-value. However, since the value being passed refers to an object, the copy of that value will still refer to the same object referred to by its corresponding argument.

Java: A Beginner's Guide, Sixth Edition, Herbert Schildt

In addition to Guffa's answer, you could use this variant to have a more shorthanded notation.

public static bool ScrambledEquals<T>(this IEnumerable<T> list1, IEnumerable<T> list2)
{
  var deletedItems = list1.Except(list2).Any();
  var newItems = list2.Except(list1).Any();
  return !newItems && !deletedItems;          
}

public void methodOnClick(View view){

Button.setBackgroundResource(R.drawable.nameImage);

}

i recommend use button inside LinearLayout for adjust to size of Linear.

You can use String unescapeJava(String) method of StringEscapeUtils from Apache Commons Lang.

Here's an example snippet:

    String in = "a\\tb\\n\\\"c\\\"";

    System.out.println(in);
    // a\tb\n\"c\"

    String out = StringEscapeUtils.unescapeJava(in);

    System.out.println(out);
    // a    b
    // "c"

The utility class has methods to escapes and unescape strings for Java, Java Script, HTML, XML, and SQL. It also has overloads that writes directly to a java.io.Writer.

Caveats

It looks like StringEscapeUtils handles Unicode escapes with one u, but not octal escapes, or Unicode escapes with extraneous us.

    /* Unicode escape test #1: PASS */
    
    System.out.println(
        "\u0030"
    ); // 0
    System.out.println(
        StringEscapeUtils.unescapeJava("\\u0030")
    ); // 0
    System.out.println(
        "\u0030".equals(StringEscapeUtils.unescapeJava("\\u0030"))
    ); // true
    
    /* Octal escape test: FAIL */
    
    System.out.println(
        "\45"
    ); // %
    System.out.println(
        StringEscapeUtils.unescapeJava("\\45")
    ); // 45
    System.out.println(
        "\45".equals(StringEscapeUtils.unescapeJava("\\45"))
    ); // false

    /* Unicode escape test #2: FAIL */
    
    System.out.println(
        "\uu0030"
    ); // 0
    System.out.println(
        StringEscapeUtils.unescapeJava("\\uu0030")
    ); // throws NestableRuntimeException:
       //   Unable to parse unicode value: u003

A quote from the JLS:

Octal escapes are provided for compatibility with C, but can express only Unicode values \u0000 through \u00FF, so Unicode escapes are usually preferred.

If your string can contain octal escapes, you may want to convert them to Unicode escapes first, or use another approach.

The extraneous u is also documented as follows:

The Java programming language specifies a standard way of transforming a program written in Unicode into ASCII that changes a program into a form that can be processed by ASCII-based tools. The transformation involves converting any Unicode escapes in the source text of the program to ASCII by adding an extra u-for example, \uxxxx becomes \uuxxxx-while simultaneously converting non-ASCII characters in the source text to Unicode escapes containing a single u each.

This transformed version is equally acceptable to a compiler for the Java programming language and represents the exact same program. The exact Unicode source can later be restored from this ASCII form by converting each escape sequence where multiple u's are present to a sequence of Unicode characters with one fewer u, while simultaneously converting each escape sequence with a single u to the corresponding single Unicode character.

If your string can contain Unicode escapes with extraneous u, then you may also need to preprocess this before using StringEscapeUtils.

Alternatively you can try to write your own Java string literal unescaper from scratch, making sure to follow the exact JLS specifications.

I have the same problem that you describe although I'm building up my LatLngBounds as proposed by above. The problem is that things are async and calling map.fitBounds() at the wrong time may leave you with a result like in the Q. The best way I found is to place the call in an idle handler like this:

google.maps.event.addListenerOnce(map, 'idle', function() {
    map.fitBounds(markerBounds);
});

If your content is a set of buttons that you want to center on a page, then wrap them in a row and use justify-content-center.

Sample code below:

<div class="row justify-content-center">

    <button>Action A</button>
    <button>Action B</button>
    <button>Action C</button> 

</div>

You have to use getStackTrace () method instead of printStackTrace(). Here is a good example:

import java.io.*;

/**
* Simple utilities to return the stack trace of an
* exception as a String.
*/
public final class StackTraceUtil {

  public static String getStackTrace(Throwable aThrowable) {
    final Writer result = new StringWriter();
    final PrintWriter printWriter = new PrintWriter(result);
    aThrowable.printStackTrace(printWriter);
    return result.toString();
  }

  /**
  * Defines a custom format for the stack trace as String.
  */
  public static String getCustomStackTrace(Throwable aThrowable) {
    //add the class name and any message passed to constructor
    final StringBuilder result = new StringBuilder( "BOO-BOO: " );
    result.append(aThrowable.toString());
    final String NEW_LINE = System.getProperty("line.separator");
    result.append(NEW_LINE);

    //add each element of the stack trace
    for (StackTraceElement element : aThrowable.getStackTrace() ){
      result.append( element );
      result.append( NEW_LINE );
    }
    return result.toString();
  }

  /** Demonstrate output.  */
  public static void main (String... aArguments){
    final Throwable throwable = new IllegalArgumentException("Blah");
    System.out.println( getStackTrace(throwable) );
    System.out.println( getCustomStackTrace(throwable) );
  }
} 

As chars can be represented as Integers (ASCII-Codes), you can simply write:

char c = 0;

The 0 in ASCII-Code is null.

The projects you are trying to open are in the new .NET Core csproj format. This means you need to use Visual Studio 2017 which supports this new format.

For a little bit of history, initially .NET Core used project.json instead of *.csproj. However, after some considerable internal deliberation at Microsoft, they decided to go back to csproj but with a much cleaner and updated format. However, this new format is only supported in VS2017.

If you want to open the projects but don't want to wait until March 7^th for the official VS2017 release, you could use Visual Studio Code instead.

As an addition, consider that, as for read-only purposes the use of both is identical, you can access a char by indexing either with [] or *(<var> + <index>) format:

printf("%c", x[1]);     //Prints r

And:

printf("%c", *(x + 1)); //Prints r

Obviously, if you attempt to do

*(x + 1) = 'a';

You will probably get a Segmentation Fault, as you are trying to access read-only memory.

A ViewGroup describes the layout of the Views in its group. The two basic examples of ViewGroups are LinearLayout and RelativeLayout. Breaking LinearLayout even further, you can have either Vertical LinearLayout or Horizontal LinearLayout. If you choose Vertical LinearLayout, your Views will stack vertically on your screen. The two most basic examples of Views are TextView and Button. Thus, if you have a ViewGroup of Vertical LinearLayout, your Views (e.g. TextViews and Buttons) would line up vertically down your screen.

When the other posters show nested ViewGroups, what they mean is, for example, one of the rows in my Vertical LinearLayout might actually, at the lower level, be several items arranged horizontally. In that case, I'd have a Horizontal LinearLayout as one of the children of my top level Vertical LinearLayout.

Example of Nested ViewGroups:
Parent ViewGroup = Vertical LinearLayout

Row1: TextView1
Row2: Button1
Row3: Image TextView2 Button2 <-- Horizontal Linear nested in Vertical Linear
Row4: TextView3
Row5: Button3

This is an old question, and I'm not sure if it will help, but I've been able to programatically fire an event using:

if (document.createEvent && ctrl.dispatchEvent) {
    var evt = document.createEvent("HTMLEvents");
    evt.initEvent("change", true, true);
    ctrl.dispatchEvent(evt); // for DOM-compliant browsers
} else if (ctrl.fireEvent) {
    ctrl.fireEvent("onchange"); // for IE
}

You can do do it. The input type submit should be inside of a form. Then all you have to do is write the link you want to redirect to inside the action attribute that is inside the form tag.

mylist[c(5,7,9)] should do it.

You want the sublists returned as sublists of the result list; you don't use [[]] (or rather, the function is [[) for that -- as Dason mentions in comments, [[ grabs the element.

You 'll find it there

~/.mysql_history

You 'll make it readable (without the escapes) like this:

sed "s/\\\040/ /g" < .mysql_history

To any of these recipes (based on git log or gitk), you can add --simplify-by-decoration to collapse the uninteresting linear parts of the history. This makes much more of the topology visible at once. I can now understand large histories that would be incomprehensible without this option!

I felt the need to post this because it doesn't seem to be as well-known as it should be. It doesn't appear in most of the Stack Overflow questions about visualizing history, and it took me quite a bit of searching to find--even after I knew I wanted it! I finally found it in this Debian bug report. The first mention on Stack Overflow seems to be this answer by Antoine Pelisse.

Actually, if you try to use function "children" it will not be succesfull because it's possible to the table has a first child like 'th'. So you have to use function 'find' instead.

Wrong way:

var $row = $(this).closest('table').children('tr:first');

Correct way:

 var $row = $(this).closest('table').find('tr:first');

The subject is almost exhausted, I 'd like though to offer a solution to a slightly more general version where you don't know the number of output columns, a priori. So for example you have

before = data.frame(attr = c(1,30,4,6), type=c('foo_and_bar','foo_and_bar_2', 'foo_and_bar_2_and_bar_3', 'foo_and_bar'))
  attr                    type
1    1             foo_and_bar
2   30           foo_and_bar_2
3    4 foo_and_bar_2_and_bar_3
4    6             foo_and_bar

We can't use dplyr separate() because we don't know the number of the result columns before the split, so I have then created a function that uses stringr to split a column, given the pattern and a name prefix for the generated columns. I hope the coding patterns used, are correct.

split_into_multiple <- function(column, pattern = ", ", into_prefix){
  cols <- str_split_fixed(column, pattern, n = Inf)
  # Sub out the ""'s returned by filling the matrix to the right, with NAs which are useful
  cols[which(cols == "")] <- NA
  cols <- as.tibble(cols)
  # name the 'cols' tibble as 'into_prefix_1', 'into_prefix_2', ..., 'into_prefix_m' 
  # where m = # columns of 'cols'
  m <- dim(cols)[2]

  names(cols) <- paste(into_prefix, 1:m, sep = "_")
  return(cols)
}

We can then use split_into_multiple in a dplyr pipe as follows:

Chacha, per the PHP documentation: "Set to a non-empty value if the script was queried through the HTTPS protocol." So your if statement there will return false in many cases where HTTPS is indeed on. You'll want to verify that $_SERVER['HTTPS'] exists and is non-empty. In cases where HTTPS is not set correctly for a given server, you can try checking if $_SERVER['SERVER_PORT'] == 443.

But note that some servers will also set $_SERVER['HTTPS'] to a non-empty value, so be sure to check this variable also.

Reference: Documentation for $_SERVER and $HTTP_SERVER_VARS [deprecated]

Thanks!It's worked. But with the mysqldb updates the configure has became:

max_allowed_packet

net_write_timeout

net_read_timeout

mysql doc

To delete all files and directories within the current directory:

find . -mtime +3 | xargs rm -Rf

Or alternatively, more in line with the OP's original command:

find . -mtime +3 -exec rm -Rf -- {} \;

simple query would be, just set a variable to some number you want. then update the column you need by incrementing 1 from that number. for all the rows it'll update each row id by incrementing 1

SET @a  = 50000835 ;  
UPDATE `civicrm_contact` SET external_identifier = @a:=@a+1 
WHERE external_identifier IS NULL;

I had downloaded it from http://gradle.org/gradle-download/. I use Homebrew, but I missed installing gradle using it.

To save some MBs by downloading it over again using Homebrew, I symlinked the gradle binary from the downloaded (and extracted) zip archive in the /usr/local/bin/. This is the same place where Homebrew symlinks all other binaries.

cd /usr/local/bin/
ln -s ~/Downloads/gradle-2.12/bin/gradle

Now check whether it works or not:

gradle -v

Yes you can. Just check my fiddle for clarification. For demo purpose i kept the code in fiddle at same location. You can extract that code as shown in two different Javascript files and load them in html file.

https://jsfiddle.net/mvora/mrLmkxmo/

 /******** PUT THIS CODE IN ONE JS FILE *******/

    var secondFileFuntion = function(){
        this.name = 'XYZ';
    }

    secondFileFuntion.prototype.getSurname = function(){
     return 'ABC';
    }


    var secondFileObject = new secondFileFuntion();

    /******** Till Here *******/

    /******** PUT THIS CODE IN SECOND JS FILE *******/

    function firstFileFunction(){
      var name = secondFileObject.name;
      var surname = secondFileObject.getSurname()
      alert(name);
      alert(surname );
    }

    firstFileFunction();

If you make an object using the constructor function and trying access the property or method from it in second file, it will give you the access of properties which are present in another file.

Just take care of sequence of including these files in index.html

This is not explicitly mentioned, but based on the following docs, I think it is implied that an app needs to declare and implement a BackupAgent in order for data backup to work, even in the case when allowBackup is set to true (which is the default value).

http://developer.android.com/reference/android/R.attr.html#allowBackup http://developer.android.com/reference/android/app/backup/BackupManager.html http://developer.android.com/guide/topics/data/backup.html

This is probably the shortest and easiest solution:

$(".myCheckBox")[0].checked = true;

or

$(".myCheckBox")[0].checked = false;

Even shorter would be:

$(".myCheckBox")[0].checked = !0;
$(".myCheckBox")[0].checked = !1;

Here is a jsFiddle as well.

To add on the earlier comments, I would like to say the following :

The setTimeout() function in JavaScript does not pause execution of the script per se, but merely tells the compiler to execute the code sometime in the future.

There isn't a function that can actually pause execution built into JavaScript. However, you can write your own function that does something like an unconditional loop till the time is reached by using the Date() function and adding the time interval you need.

if you like another alternate approach with up and down method try this:

  def up
    change_table :uploads do |t|
      t.references :user, index: true
    end
  end

  def down
    change_table :uploads do |t|
      t.remove_references :user, index: true
    end
  end

Simple is better, one variable, one function :)

const counts = arr.reduce((acc, value) => ({
   ...acc,
   [value]: (acc[value] || 0) + 1
}), {});

The function datepicker is case sensitive and all lowercase. The following however works fine for me:

$(document).ready(function() {
  $('.date-pick').datepicker( {
    onSelect: function(date) {
        alert(date);
    },
    selectWeek: true,
    inline: true,
    startDate: '01/01/2000',
    firstDay: 1
  });
});

Most likely JDK configuration is not valid, try to remove and add the JDK again as I've described in the related question here.

I had the same issue, I could solve it by switching fom JDK 11 to JDK 8.

If your images are named you can reference them through the DOM and change the source.

document["imgName"].src="../newImgSrc.jpg";

or

document.getElementById("imgName").src="../newImgSrc.jpg";

I was able to cut and paste your code into a file and it ran correctly. If you execute it like this it should work:

Your "file.sh":

#!/bin/bash
# june 2011

if [ $# -lt 3 -o $# -gt 3 ]; then
   echo "Error... Usage: $0 host database username"
   exit 0
fi

The command:

$ ./file.sh arg1 arg2 arg3

Note that "file.sh" must be executable:

$ chmod +x file.sh

You may be getting that error b/c of how you're doing input (w/ a pipe, carrot, etc.). You could also try splitting the condition into two:

if [ $# -lt 3 ] || [ $# -gt 3 ]; then
   echo "Error... Usage: $0 host database username"
   exit 0
fi

Or, since you're using bash, you could use built-in syntax:

if [[ $# -lt 3 || $# -gt 3 ]]; then
   echo "Error... Usage: $0 host database username"
   exit 0
fi

And, finally, you could of course just check if 3 arguments were given (clean, maintains POSIX shell compatibility):

if [ $# -ne 3 ]; then
   echo "Error... Usage: $0 host database username"
   exit 0
fi

Note that usage of a SerialPort.DataReceived event is optional. You can set proper timeout using SerialPort.ReadTimeout and continuously call SerialPort.Read() after you wrote something to a port until you get a full response.

Moreover you can use SerialPort.BaseStream property to extract an underlying Stream instance. The benefit of using a Stream is that you can easily utilize various decorators with it:

var port = new SerialPort();
// LoggingStream inherits Stream, implements IDisposable, needen abstract methods and 
// overrides needen virtual methods. 
Stream portStream = new LoggingStream(port.BaseStream);
portStream.Write(...); // Logs write buffer.
portStream.Read(...); // Logs read buffer.

For more information check:

I know this question is old, but it's got a lot of attention over the years and I think it's missing a concept which may help someone in a similar case. I'm adding it here for completeness sake.

If you cannot modify your original database schema, then a lot of good answers have been provided and solve the problem just fine.

If you can, however, modify your schema, I would advise to add a field in your customer table that holds the id of the latest customer_data record for this customer:

CREATE TABLE customer (
  id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
  current_data_id INT UNSIGNED NULL DEFAULT NULL
);

CREATE TABLE customer_data (
   id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
   customer_id INT UNSIGNED NOT NULL, 
   title VARCHAR(10) NOT NULL,
   forename VARCHAR(10) NOT NULL,
   surname VARCHAR(10) NOT NULL
);

Querying customers

Querying is as easy and fast as it can be:

SELECT c.*, d.title, d.forename, d.surname
FROM customer c
INNER JOIN customer_data d on d.id = c.current_data_id
WHERE ...;

The drawback is the extra complexity when creating or updating a customer.

Updating a customer

Whenever you want to update a customer, you insert a new record in the customer_data table, and update the customer record.

INSERT INTO customer_data (customer_id, title, forename, surname) VALUES(2, 'Mr', 'John', 'Smith');
UPDATE customer SET current_data_id = LAST_INSERT_ID() WHERE id = 2;

Creating a customer

Creating a customer is just a matter of inserting the customer entry, then running the same statements:

INSERT INTO customer () VALUES ();

SET @customer_id = LAST_INSERT_ID();
INSERT INTO customer_data (customer_id, title, forename, surname) VALUES(@customer_id, 'Mr', 'John', 'Smith');
UPDATE customer SET current_data_id = LAST_INSERT_ID() WHERE id = @customer_id;

Wrapping up

The extra complexity for creating/updating a customer might be fearsome, but it can easily be automated with triggers.

Finally, if you're using an ORM, this can be really easy to manage. The ORM can take care of inserting the values, updating the ids, and joining the two tables automatically for you.

Here is how your mutable Customer model would look like:

class Customer
{
    private int id;
    private CustomerData currentData;

    public Customer(String title, String forename, String surname)
    {
        this.update(title, forename, surname);
    }

    public void update(String title, String forename, String surname)
    {
        this.currentData = new CustomerData(this, title, forename, surname);
    }

    public String getTitle()
    {
        return this.currentData.getTitle();
    }

    public String getForename()
    {
        return this.currentData.getForename();
    }

    public String getSurname()
    {
        return this.currentData.getSurname();
    }
}

And your immutable CustomerData model, that contains only getters:

class CustomerData
{
    private int id;
    private Customer customer;
    private String title;
    private String forename;
    private String surname;

    public CustomerData(Customer customer, String title, String forename, String surname)
    {
        this.customer = customer;
        this.title    = title;
        this.forename = forename;
        this.surname  = surname;
    }

    public String getTitle()
    {
        return this.title;
    }

    public String getForename()
    {
        return this.forename;
    }

    public String getSurname()
    {
        return this.surname;
    }
}

All POSIX operating systems have 3 streams: stdin, stdout, and stderr. stdin is the input, which can accept the stdout or stderr. stdout is the primary output, which is redirected with >, >>, or |. stderr is the error output, which is handled separately so that any exceptions do not get passed to a command or written to a file that it might break; normally, this is sent to a log of some kind, or dumped directly, even when the stdout is redirected. To redirect both to the same place, use:

command &> /some/file

EDIT: thanks to Zack for pointing out that the above solution is not portable--use instead:

*command* > file 2>&1 

If you want to silence the error, do:

*command* 2> /dev/null

String str1="this is a string";
String str2=str1.clone();

How about copy like this? I think to get a new copy is better, so that the data of str1 won't be affected when str2 is reference and modified in futher action.

Googled "Permission denied (publickey). fatal: The remote end hung up unexpectedly", first result an exact SO dupe:

GitHub: Permission denied (publickey). fatal: The remote end hung up unexpectedly which links here in the accepted answer (from the original poster, no less): http://help.github.com/linux-set-up-git/

you can do it like this:

cell[B1]: 0:04:58.727

cell[B2]: =FIND(".";B1)

cell[B3]: =LEFT(B1;B2-7)

cell[B4]: =MID(B1;11-8;2)

cell[B5]: =RIGHT(B1;6)

cell[B6]: =B3*3600000+B4*60000+B5

maybe you have to multiply B5 also with 1000.

=FIND(".";B1) is only necessary because you might have inputs like '0:04:58.727' or '10:04:58.727' with different length.

You should be able to perform a select on the orders table, using a raw WHERE to find the max(id) in a subquery, like this:

 \DB::table('orders')->where('id', \DB::raw("(select max(`id`) from orders)"))->get();

If you want to use Eloquent (for example, so you can convert your response to an object) you will want to use whereRaw, because some functions such as toJSON or toArray will not work without using Eloquent models.

 $order = Order::whereRaw('id = (select max(`id`) from orders)')->get();

That, of course, requires that you have a model that extends Eloquent.

 class Order extends Eloquent {}

As mentioned in the comments, you don't need to use whereRaw, you can do the entire query using the query builder without raw SQL.

 // Using the Query Builder
 \DB::table('orders')->find(\DB::table('orders')->max('id'));

 // Using Eloquent
 $order = Order::find(\DB::table('orders')->max('id'));

(Note that if the id field is not unique, you will only get one row back - this is because find() will only return the first result from the SQL server.).

I had a similar problem, but only on startup;

To resolve my start issue:

I have removed extensions from Visual Studio 2012 for phones;

Repair Visual Studio 2015 same… uninstall Visual Studio 2015 (hang, not all removed)

Then use:

https://github.com/tsasioglu/Total-Uninstaller

Remove all that was possible with Visual Studio 2015, Visual Studio 2013, etc.

Install Visual Studio again error: Lookup logs, inet, etc. and found Visual C++ redist 2015. I reinstalled and repaired vc_redist.x64.exe and vc_redist.x86.exe.

I installed Visual Studio 2015 again and now I don't have any startup issues (vsHub can be uninstalled and connected services can be disabled…)

As @TechSpellBound suggested remove the quotes around the ? signs. Then add a space character at the end of each row in your concatenated string. Otherwise the entire query will be sent as (using only part of it as an example) : .... WHERE bookings.booking_end < date ?OR bookings.booking_start > date ?GROUP BY ....

The ? and the OR needs to be seperated by a space character. Do it wherever needed in the query string.

I've been learning about dynamic programming today, and here's the result:

coins = [1,5,10,25]
d = {} # stores tuples of the form (# of coins, [coin list])

# finds the minimum # of coins needed to
# make change for some number of cents
def m(cents):
    if cents in d.keys():
        return d[cents]
    elif cents > 0:
        choices = [(m(cents - x)[0] + 1, m(cents - x)[1] + [x]) for x in coins if cents >= x]

        # given a list of tuples, python's min function
        # uses the first element of each tuple for comparison
        d[cents] = min(choices)
        return d[cents]
    else:
        d[0] = (0, [])
        return d[0]

for x in range(1, 100):
    val = m(x)
    print x, "cents requires", val[0], "coins:", val[1]

Dynamic programming really is magical.

Since swift 3.0 there is more convenient way: #imageLiterals here is text example. And below animated example from here:

You should deploy "Client Profile" instead of "Full Framework" inside a corporation mostly in one case only: you want explicitly deny some .NET features are running on the client computers. The only real case is denying of ASP.NET on the client machines of the corporation, for example, because of security reasons or the existing corporate policy.

Saving of less than 8 MB on client computer can not be a serious reason of "Client Profile" deployment in a corporation. The risk of the necessity of the deployment of the "Full Framework" later in the corporation is higher than costs of 8 MB per client.

In my case I had one local commit, which wasn't pushed to origin\master, but commited to my local master branch. This local commit should be now pushed to another branch.

With Git Extensions you can do something like this:

• (Create if not existing and) checkout new branch, where you want to push your commit.
• Select the commit from the history, which should get commited & pushed to this branch.
• Right click and select Cherry pick commit.
• Press Cherry pick button afterwards.
• The selected commit get's applied to your checked out branch. Now commit and push it.
• Check out your old branch, with the faulty commit.
• Hard reset this branch to the second last commit, where everything was ok (be aware what are you doing here!). You can do that via right click on the second last commit and select Reset current branch to here. Confirm the opperation, if you know what you are doing.

You could also do that on the GIT command line. Example copied from David Christensen:

I think you'll find git cherry-pick + git reset to be a much quicker workflow:

Using your same scenario, with "feature" being the branch with the top-most commit being incorrect, it'd be much easier to do this:

git checkout master
git cherry-pick feature
git checkout feature
git reset --hard HEAD^

Saves quite a bit of work, and is the scenario that git cherry-pick was designed to handle.

I'll also note that this will work as well if it's not the topmost commit; you just need a commitish for the argument to cherry-pick, via:

git checkout master
git cherry-pick $sha1
git checkout feature
git rebase -i ... # whack the specific commit from the history

group by default order by pk id,so the result
username point avg_time
demo123 100 90 ---> id = 4
demo123456 100 100 ---> id = 7
demo 90 120 ---> id = 1

Please make sure you haven't opened Visual Studio in administrator mode

I faced this issue and had to run in normal mode.

Since Java 8 you can use the Math.floorMod() method:

Math.floorMod(-1, 2); //== 1

Note: If the modulo-value (here 2) is negative, all output values will be negative too. :)

I don't think you can give a path to curl, but you can CD to the location, download and CD back.

cd target/path && { curl -O URL ; cd -; }

Or using subshell.

(cd target/path && curl -O URL)

Both ways will only download if path exists. -O keeps remote file name. After download it will return to original location.

If you need to set filename explicitly, you can use small -o option:

curl -o target/path/filename URL

Underscore-java library has static method U.jsonToXml(jsonstring). I am the maintainer of the project. Live example

import com.github.underscore.lodash.U;

public class MyClass {
    public static void main(String args[]) {
        String json = "{\"name\":\"JSON\",\"integer\":1,\"double\":2.0,\"boolean\":true,\"nested\":{\"id\":42},\"array\":[1,2,3]}";  
        System.out.println(json); 
        String xml = U.jsonToXml(json);  
        System.out.println(xml); 
    }
}

Output:

{"name":"JSON","integer":1,"double":2.0,"boolean":true,"nested":{"id":42},"array":[1,2,3]}
<?xml version="1.0" encoding="UTF-8"?>
<root>
  <name>JSON</name>
  <integer number="true">1</integer>
  <double number="true">2.0</double>
  <boolean boolean="true">true</boolean>
  <nested>
    <id number="true">42</id>
  </nested>
  <array number="true">1</array>
  <array number="true">2</array>
  <array number="true">3</array>
</root>

If you throw an exception without a variable (the second example) the StackTrace will include the original method that threw the exception.

In the first example the StackTrace will be changed to reflect the current method.

Example:

static string ReadAFile(string fileName) {
    string result = string.Empty;
    try {
        result = File.ReadAllLines(fileName);
    } catch(Exception ex) {
        throw ex; // This will show ReadAFile in the StackTrace
        throw;    // This will show ReadAllLines in the StackTrace
    }

I use this script to quickly find files across directories in a project. I have found it works great and takes advantage of Vim's autocomplete by opening up and closing an new buffer for the search. It also smartly completes as much as possible for you so you can usually just type a character or two and open the file across any directory in your project. I started using it specifically because of a Java project and it has saved me a lot of time. You just build the cache once when you start your editing session by typing :FC (directory names). You can also just use . to get the current directory and all subdirectories. After that you just type :FF (or FS to open up a new split) and it will open up a new buffer to select the file you want. After you select the file the temp buffer closes and you are inside the requested file and can start editing. In addition, here is another link on Stack Overflow that may help.

Wow. I found this solution, but nothing worked like I wanted. But this is so good:

EventHandlerList listaEventos;

private void btnDetach_Click(object sender, EventArgs e)
{
    listaEventos = DetachEvents(comboBox1);
}

private void btnAttach_Click(object sender, EventArgs e)
{
    AttachEvents(comboBox1, listaEventos);
}

public EventHandlerList DetachEvents(Component obj)
{
    object objNew = obj.GetType().GetConstructor(new Type[] { }).Invoke(new object[] { });
    PropertyInfo propEvents = obj.GetType().GetProperty("Events", BindingFlags.NonPublic | BindingFlags.Instance);

    EventHandlerList eventHandlerList_obj = (EventHandlerList)propEvents.GetValue(obj, null);
    EventHandlerList eventHandlerList_objNew = (EventHandlerList)propEvents.GetValue(objNew, null);

    eventHandlerList_objNew.AddHandlers(eventHandlerList_obj);
    eventHandlerList_obj.Dispose();

    return eventHandlerList_objNew;
}

public void AttachEvents(Component obj, EventHandlerList eventos)
{
    PropertyInfo propEvents = obj.GetType().GetProperty("Events", BindingFlags.NonPublic | BindingFlags.Instance);

    EventHandlerList eventHandlerList_obj = (EventHandlerList)propEvents.GetValue(obj, null);

    eventHandlerList_obj.AddHandlers(eventos);
}

Use:

if (function_exists('curl_file_create')) { // php 5.5+
  $cFile = curl_file_create($file_name_with_full_path);
} else { // 
  $cFile = '@' . realpath($file_name_with_full_path);
}
$post = array('extra_info' => '123456','file_contents'=> $cFile);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);

You can also refer:

http://blog.derakkilgo.com/2009/06/07/send-a-file-via-post-with-curl-and-php/

Important hint for PHP 5.5+:

Now we should use https://wiki.php.net/rfc/curl-file-upload but if you still want to use this deprecated approach then you need to set curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);

You could also make it a post-build step. Setup a new configuration which is "Deploy" in addition to Debug and Release, and then have the post-build step copy over the correct web.config.

We use automated builds for all of our projects, and with those the build script updates the web.config file to point to the correct location. But that won't help you if you are doing everything from VS.

Working with cursors consists of several steps:

Declare - Declare is used to define a new cursor. Open - A Cursor is opened and populated by executing the SQL statement defined by the cursor. Fetch - When the cursor is opened, rows can be retrieved from the cursor one by one. Close - After data operations, we should close the cursor explicitly. Deallocate - Finally, we need to delete the cursor definition and release all the system resources associated with the cursor. Syntax

DECLARE cursor_name CURSOR [ LOCAL | GLOBAL ] [ FORWARD_ONLY | SCROLL ] [ STATIC | KEYSET | DYNAMIC | FAST_FORWARD ] [ READ_ONLY | SCROLL_LOCKS | OPTIMISTIC ] [ TYPE_WARNING] FOR select_statement [FOR UPDATE [ OF column_name [ ,...n ] ] ] [;]

Similar to @Triptych answer but also different. In this example list or dictionary is not used. Code is written in Ruby

def largest_prime_factor(number)
  i = 2
  while number > 1
    if number % i == 0
      number /= i;
    else
      i += 1
    end
  end
  return i
end

largest_prime_factor(600851475143)
# => 6857

If you are using Jquery > 1.4, you are best of with Ian's answer. Otherwise, I would use this method:

This is very similar to celoron's answer, but I don't know why they used document.createElement instead of Jquery notation.

$("body").append(function(){
        return $("<div/>").html("I'm a freshly created div. I also contain some Ps!")
            .attr("id","myDivId")
            .addClass("myDivClass")
            .css("border", "solid")                 
            .append($("<p/>").html("I think, therefore I am."))
            .append($("<p/>").html("The die is cast."))
});

//Some style, for better demonstration if you want to try it out. Don't use this approach for actual design and layout!
$("body").append($("<style/>").html("p{background-color:blue;}div{background-color:yellow;}div>p{color:white;}"));

I also think using append() with a callback function is in this case more readable, because you now immediately that something is going to be appended to the body. But that is a matter of taste, as always when writing any code or text.

In general, use as less HTML as possible in JQuery code, since this is mostly spaghetti code. It is error prone and hard to maintain, because the HTML-String can easily contain typos. Also, it mixes a markup language (HTML) with a programming language (Javascript/Jquery), which is usually a bad Idea.

1. Create the UDF:

CREATE FUNCTION CombineValues
(
    @FK_ID INT -- The foreign key from TableA which is used 
               -- to fetch corresponding records
)
RETURNS VARCHAR(8000)
AS
BEGIN
DECLARE @SomeColumnList VARCHAR(8000);

SELECT @SomeColumnList =
    COALESCE(@SomeColumnList + ', ', '') + CAST(SomeColumn AS varchar(20)) 
FROM TableB C
WHERE C.FK_ID = @FK_ID;

RETURN 
(
    SELECT @SomeColumnList
)
END

2. Use in subquery:

SELECT ID, Name, dbo.CombineValues(FK_ID) FROM TableA

3. If you are using stored procedure you can do like this:

CREATE PROCEDURE GetCombinedValues
 @FK_ID int
As
BEGIN
DECLARE @SomeColumnList VARCHAR(800)
SELECT @SomeColumnList =
    COALESCE(@SomeColumnList + ', ', '') + CAST(SomeColumn AS varchar(20)) 
FROM TableB
WHERE FK_ID = @FK_ID 

Select *, @SomeColumnList as SelectedIds
    FROM 
        TableA
    WHERE 
        FK_ID = @FK_ID 
END

You have to set the weight property of your elements. Create three RelativeLayouts as children to your LinearLayout and set weights 0.15, 0.70, 0.15. Then add your buttons to the second RelativeLayout(the one with weight 0.70).

Like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:id="@+id/layoutContainer" android:orientation="horizontal">
    <RelativeLayout
        android:layout_width="0dip"
        android:layout_height="fill_parent"
        android:layout_weight="0.15">
    </RelativeLayout>
    <RelativeLayout
        android:layout_width="0dip"
        android:layout_height="fill_parent"
        android:layout_weight="0.7">
        
        <!-- This is the part that's 70% of the total width. I'm inserting a LinearLayout and buttons.-->   
            <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:orientation="vertical">
                
                <Button 
                    android:text="Button1"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content">
                </Button>
                <Button
                    android:text="Button2"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content">
                </Button>
                <Button
                    android:text="Button3"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content">
                </Button>
                
            </LinearLayout>
        <!-- 70% Width End-->
        
    </RelativeLayout>
    <RelativeLayout
        android:layout_width="0dip"
        android:layout_height="fill_parent"
        android:layout_weight="0.15">
    </RelativeLayout>
</LinearLayout>

Why are the weights 0.15, 0.7 and 0.15? Because the total weight is 1 and 0.7 is 70% of the total.

Result:

Edit: Thanks to @SimonVeloper for pointing out that the orientation should be horizontal and not vertical and to @Andrew for pointing out that weights can be decimals instead of integers.

In the view controller you are using:

//suppose you are using the textfield label as this

@IBOutlet weak var emailLabel: UITextField!
@IBOutlet weak var passwordLabel: UITextField!

//then your viewdidload should have the code like this
override func viewDidLoad() {
        super.viewDidLoad()

        self.emailLabel.delegate = self
        self.passwordLabel.delegate = self

    }

//then you should implement the func named textFieldShouldReturn
 func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        textField.resignFirstResponder()
        return true
    }

// -- then, further if you want to close the keyboard when pressed somewhere else on the screen you can implement the following method too:

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        self.view.endEditing(true);
    }

I spent some time on this very problem - I was trying to verify a file existed before opening it.

Eventually, I came up with a solution using XML and SOAP - use the EnumerateFolder method and pull in an XML response with the folder's contents.

I blogged about it here.

In my case I had to update windows first, after that the problem has gone.

Time and Space complexity are different aspects of calculating the efficiency of an algorithm.

Time complexity deals with finding out how the computational time of an algorithm changes with the change in size of the input.

On the other hand, space complexity deals with finding out how much (extra)space would be required by the algorithm with change in the input size.

To calculate time complexity of the algorithm the best way is to check if we increase in the size of the input, will the number of comparison(or computational steps) also increase and to calculate space complexity the best bet is to see additional memory requirement of the algorithm also changes with the change in the size of the input.

A good example could be of Bubble sort.

Lets say you tried to sort an array of 5 elements. In the first pass you will compare 1st element with next 4 elements. In second pass you will compare 2nd element with next 3 elements and you will continue this procedure till you fully exhaust the list.

Now what will happen if you try to sort 10 elements. In this case you will start with comparing comparing 1st element with next 9 elements, then 2nd with next 8 elements and so on. In other words if you have N element array you will start of by comparing 1st element with N-1 elements, then 2nd element with N-2 elements and so on. This results in O(N^2) time complexity.

But what about size. When you sorted 5 element or 10 element array did you use any additional buffer or memory space. You might say Yes, I did use a temporary variable to make the swap. But did the number of variables changed when you increased the size of array from 5 to 10. No, Irrespective of what is the size of the input you will always use a single variable to do the swap. Well, this means that the size of the input has nothing to do with the additional space you will require resulting in O(1) or constant space complexity.

Now as an exercise for you, research about the time and space complexity of merge sort

Note that apart from rows and columns there is a number of channels and type. When it is clear what type is, the channels can act as an extra dimension as in CV_8UC3 so you would address a matrix as

uchar a = M.at<Vec3b>(y, x)[i];

So the size in terms of elements of elementary type is M.rows * M.cols * M.cn

To find the max element one can use

Mat src;
double minVal, maxVal;
minMaxLoc(src, &minVal, &maxVal);

pip install --user <package name> (no sudo needed) worked for me for a very similar problem.
