You can either use (on the h4 elements, as they are block by default)

display: inline-block;

Or you can float the elements to the left/rght

float: left;

Just don't forget to clear the floats after

clear: left;

More visual example for the float left/right option as shared below by @VSB:

<h4> _x000D_
    <div style="float:left;">Left Text</div>_x000D_
    <div style="float:right;">Right Text</div>_x000D_
    <div style="clear: left;"/>_x000D_
</h4>

Sure that is possible. This is what GObject, the framework that all of GTK+ and GNOME is based on, does.

WWW-Authenticate header

You may also get this if the server is sending a 401 response code but not setting the WWW-Authenticate header correctly - I should know, I've just fixed that in out own code because VB apps weren't popping up the authentication prompt.

If you know the full path to the file you can just do something similar to this. However if you question directly relates to relative paths, that I am unfamiliar with and would have to research and test.

path = 'C:\\Users\\Username\\Path\\To\\File'

with open(path, 'w') as f:
    f.write(data)

Edit:

Here is a way to do it relatively instead of absolute. Not sure if this works on windows, you will have to test it.

import os

cur_path = os.path.dirname(__file__)

new_path = os.path.relpath('..\\subfldr1\\testfile.txt', cur_path)
with open(new_path, 'w') as f:
    f.write(data)

Edit 2: One quick note about __file__, this will not work in the interactive interpreter due it being ran interactively and not from an actual file.

This is what I have done in order to get the column "first_name" fill the space when all the columns cannot do it.

When the grid go to small the column "first_name" gets almost invisible (very thin) so I can set the DataGridViewAutoSizeColumnMode to AllCells as the others visible columns. For performance issues it´s important to set them to None before data binding it and set back to AllCell in the DataBindingComplete event handler of the grid. Hope it helps!

private void dataGridView1_Resize(object sender, EventArgs e)
    {
        int ColumnsWidth = 0;
        foreach(DataGridViewColumn col in dataGridView1.Columns)
        {
            if (col.Visible) ColumnsWidth += col.Width;
        }

        if (ColumnsWidth <dataGridView1.Width)
        {
            dataGridView1.Columns["first_name"].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
        }
        else if (dataGridView1.Columns["first_name"].Width < 10) dataGridView1.Columns["first_name"].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
    }

it would be simple to get the length as

  `${NUM}`.length

where NUM is the number to get the length for

The underscore is the wildcard in a LIKE query for one arbitrary character.

Hence LIKE %_% means "give me all records with at least one arbitrary character in this column".

You have to escape the wildcard character, in sql-server with [] around:

SELECT m.* 
FROM Manager m 
WHERE m.managerid    LIKE  '[_]%'
AND   m.managername  LIKE '%[_]%'

See: LIKE (Transact-SQL)

Demo

you can give git pattern as version, yarn and npm are clever enough to resolve from a git repo.

yarn add any-package@user-name/repo-name#branch-name

or for npm

npm install --save any-package@user-name/repo-name#branch-name

Here is a solution in php that:

• copies the directories (not recursively, only one level)
• preserves permissions
• unlike the rsync solution, is fast even with directories containing thousands of files as it does not even go into the folders
• has no problems with spaces
• should be easy to read and adjust

Create a file like syncDirs.php with this content:

<?php
foreach (new DirectoryIterator($argv[1]) as $f) {
    if($f->isDot() || !$f->isDir()) continue;
        mkdir($argv[2].'/'.$f->getFilename(), $f->getPerms());
        chown($argv[2].'/'.$f->getFilename(), $f->getOwner());
        chgrp($argv[2].'/'.$f->getFilename(), $f->getGroup());
}

Run it as user that has enough rights:

sudo php syncDirs.php /var/source /var/destination

You can use INFORMATION_SCHEMA.TABLES to retrieve information about your database tables.

As mentioned in the Microsoft Tables Documentation:

INFORMATION_SCHEMA.TABLES returns one row for each table in the current database for which the current user has permissions.

The following query, therefore, will return the number of tables in the specified database:

USE MyDatabase
SELECT COUNT(*)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'

As of SQL Server 2008, you can also use sys.tables to count the the number of tables.

From the Microsoft sys.tables Documentation:

sys.tables returns a row for each user table in SQL Server.

The following query will also return the number of table in your database:

SELECT COUNT(*)
FROM sys.tables

Apparently, org.json.simple.JSONArray implements a raw Iterator. This means that each element is considered to be an Object. You can try to cast:

for(Object o: arr){
    if ( o instanceof JSONObject ) {
        parse((JSONObject)o);
    }
}

This is how things were done back in Java 1.4 and earlier.

As noted in the accepted answer - you can use the special { props.children } property. However - you can just pass a component as a prop as the title requests. I think this is cleaner sometimes as you might want to pass several components and have them render in different places. Here's the react docs with an example of how to do it:

https://reactjs.org/docs/composition-vs-inheritance.html

Make sure you are actually passing a component and not an object (this tripped me up initially).

The code is simply this:

const Parent = () => { 
  return (
    <Child  componentToPassDown={<SomeComp />}  />
  )
}

const Child = ({ componentToPassDown }) => { 
  return (
    <>
     {componentToPassDown}  
    </>
  )
}

I prefer to have the server return the date without modification, and have javascript do the view massaging. My API returns "MM/DD/YYYY hh:mm:ss" from SQL Server.

Resource

angular.module('myApp').factory('myResource',
    function($resource) {
        return $resource('api/myRestEndpoint/', null,
        {
            'GET': { method: 'GET' },
            'QUERY': { method: 'GET', isArray: true },
            'POST': { method: 'POST' },
            'PUT': { method: 'PUT' },
            'DELETE': { method: 'DELETE' }
        });
    }
);

Controller

var getHttpJson = function () {
    return myResource.GET().$promise.then(
        function (response) {

            if (response.myDateExample) {
                response.myDateExample = $filter('date')(new Date(response.myDateExample), 'M/d/yyyy');
            };

            $scope.myModel= response;
        },
        function (response) {
            console.log(response.data);
        }
    );
};

myDate Validation Directive

angular.module('myApp').directive('myDate',
    function($window) {
        return {
            require: 'ngModel',
            link: function(scope, element, attrs, ngModel) {

                var moment = $window.moment;

                var acceptableFormats = ['M/D/YYYY', 'M-D-YYYY'];

                function isDate(value) {

                    var m = moment(value, acceptableFormats, true);

                    var isValid = m.isValid();

                    //console.log(value);
                    //console.log(isValid);

                    return isValid;

                };

                ngModel.$parsers.push(function(value) {

                    if (!value || value.length === 0) {
                         return value;
                    };

                    if (isDate(value)) {
                        ngModel.$setValidity('myDate', true);
                    } else {
                        ngModel.$setValidity('myDate', false);
                    }

                    return value;

                });

            }
        }
    }
);

This bash script is for N parallel threads. Each argument is a command.

trap will kill all subprocesses when SIGINT is catched.
wait $PID_LIST is waiting each process to complete. When all processes have completed, the program exits.

#!/bin/bash

for cmd in "$@"; do {
  echo "Process \"$cmd\" started";
  $cmd & pid=$!
  PID_LIST+=" $pid";
} done

trap "kill $PID_LIST" SIGINT

echo "Parallel processes have started";

wait $PID_LIST

echo
echo "All processes have completed";

Save this script as parallel_commands and make it executable.
This is how to use this script:

parallel_commands "cmd arg0 arg1 arg2" "other_cmd arg0 arg2 arg3"

Example:

parallel_commands "sleep 1" "sleep 2" "sleep 3" "sleep 4"

Start 4 parallel sleep and waits until "sleep 4" finishes.

As Victor pointed out, the problem is with the alias. This can be avoided though, by putting the expression directly into the WHERE x IN y clause:

SELECT `users`.`first_name`,`users`.`last_name`,`users`.`email`,SUBSTRING(`locations`.`raw`,-6,4) AS `guaranteed_postcode`
FROM `users` LEFT OUTER JOIN `locations`
ON `users`.`id` = `locations`.`user_id`
WHERE SUBSTRING(`locations`.`raw`,-6,4) NOT IN #this is where the fake col is being used
(
 SELECT `postcode` FROM `postcodes` WHERE `region` IN
 (
  'australia'
 )
)

However, I guess this is very inefficient, since the subquery has to be executed for every row of the outer query.

Above answers are bit old.

Firstly create a key-pair and then attach it to Elastic Beanstalk environment.

Steps to create a key-pair

1. Login to AWS
2. Services -> EC2
3. In left under NETWORK & SECURITY select key pairs
4. Select Create new Key Pair, type key name and click on create. The key will be automatically downloaded to your system.

Steps to attach created key pair to Elastic Beanstalk environment

1. AWS -> Services -> Elastic Beanstalk

2. Select your environment and click on the configuration in left.

3. In Configuration overview select modify from Security.

4. Under Virtual machine permissions select key-pair that we created.

5. Click on save and then on save configuration.

This will take some time to reflect to your EC2 instance.

internal is for assembly scope (i.e. only accessible from code in the same .exe or .dll)

private is for class scope (i.e. accessible only from code in the same class).

Use the built in date_sub and date_add functions to math with dates. (See http://php.net/manual/en/datetime.sub.php)

Similar to Sazzad's answer, but in procedural style PHP,

$date = date_create('2008-12-02');
date_sub($date, date_interval_create_from_date_string('5 days'));
echo date_format($date, 'Y-m-d'); //outputs 2008-11-27

The other answers didn't work for me, but this did:

del /s /q *.svn
rmdir /s /q *.svn

/q disables Yes/No prompting

/s means delete the file(s) from all subdirectories.

size_t is the result type of the sizeof operator.

Use size_t for variables that model size or index in an array. size_t conveys semantics: you immediately know it represents a size in bytes or an index, rather than just another integer.

Also, using size_t to represent a size in bytes helps making the code portable.

Instead of specifying a list of directories to ignore (e.g. negative), you can also specify a list of directories to watch (e.g positive):

nodemon --watch dir1 --watch dir2  dir1/examples/index.js

In my particular case, I had one directory I wanted to watch and about nine I wanted to ignore, so specifying '--watch' was much simpler than specifying '--ignore'

To check if a value is Int in Mysql, we can use the following query. This query will give the rows with Int values

SELECT col1 FROM table WHERE concat('',col * 1) = col;

I don't know if you fixed it, but I did had the same issue, finally it was a dumb thing, I had:

<script src="jquery-ui/jquery-ui.min.css" rel="stylesheet">

but it should be:

<link href="jquery-ui/jquery-ui.min.css" rel="stylesheet">

Just change <scrip> to <link> and src to href

Create a dictionary with tuple as the key, and print the keys.

• create dictionary with tuple as key and index as value
• print list of keys of dictionary

k = [[1, 2], [4], [5, 6, 2], [1, 2], [3], [4]]

dict_tuple = {tuple(item): index for index, item in enumerate(k)}

print [list(itm) for itm in dict_tuple.keys()]

# prints [[1, 2], [5, 6, 2], [3], [4]]

.init/.fini isn't deprecated. It's still part of the the ELF standard and I'd dare say it will be forever. Code in .init/.fini is run by the loader/runtime-linker when code is loaded/unloaded. I.e. on each ELF load (for example a shared library) code in .init will be run. It's still possible to use that mechanism to achieve about the same thing as with __attribute__((constructor))/((destructor)). It's old-school but it has some benefits.

.ctors/.dtors mechanism for example require support by system-rtl/loader/linker-script. This is far from certain to be available on all systems, for example deeply embedded systems where code executes on bare metal. I.e. even if __attribute__((constructor))/((destructor)) is supported by GCC, it's not certain it will run as it's up to the linker to organize it and to the loader (or in some cases, boot-code) to run it. To use .init/.fini instead, the easiest way is to use linker flags: -init & -fini (i.e. from GCC command line, syntax would be -Wl -init my_init -fini my_fini).

On system supporting both methods, one possible benefit is that code in .init is run before .ctors and code in .fini after .dtors. If order is relevant that's at least one crude but easy way to distinguish between init/exit functions.

A major drawback is that you can't easily have more than one _init and one _fini function per each loadable module and would probably have to fragment code in more .so than motivated. Another is that when using the linker method described above, one replaces the original _init and _fini default functions (provided by crti.o). This is where all sorts of initialization usually occur (on Linux this is where global variable assignment is initialized). A way around that is described here

Notice in the link above that a cascading to the original _init() is not needed as it's still in place. The call in the inline assembly however is x86-mnemonic and calling a function from assembly would look completely different for many other architectures (like ARM for example). I.e. code is not transparent.

.init/.fini and .ctors/.detors mechanisms are similar, but not quite. Code in .init/.fini runs "as is". I.e. you can have several functions in .init/.fini, but it is AFAIK syntactically difficult to put them there fully transparently in pure C without breaking up code in many small .so files.

.ctors/.dtors are differently organized than .init/.fini. .ctors/.dtors sections are both just tables with pointers to functions, and the "caller" is a system-provided loop that calls each function indirectly. I.e. the loop-caller can be architecture specific, but as it's part of the system (if it exists at all i.e.) it doesn't matter.

The following snippet adds new function pointers to the .ctors function array, principally the same way as __attribute__((constructor)) does (method can coexist with __attribute__((constructor))).

#define SECTION( S ) __attribute__ ((section ( S )))
void test(void) {
   printf("Hello\n");
}
void (*funcptr)(void) SECTION(".ctors") =test;
void (*funcptr2)(void) SECTION(".ctors") =test;
void (*funcptr3)(void) SECTION(".dtors") =test;

One can also add the function pointers to a completely different self-invented section. A modified linker script and an additional function mimicking the loader .ctors/.dtors loop is needed in such case. But with it one can achieve better control over execution order, add in-argument and return code handling e.t.a. (In a C++ project for example, it would be useful if in need of something running before or after global constructors).

I'd prefer __attribute__((constructor))/((destructor)) where possible, it's a simple and elegant solution even it feels like cheating. For bare-metal coders like myself, this is just not always an option.

Some good reference in the book Linkers & loaders.

I have a bash script that calls a small python routine to display a message window. As I need to use killall to stop the python script I can't use the above method as it would then mean running killall python which could take out other python programmes so I use

pythonprog.py "$argument" & # The & returns control straight to the bash script so must be outside the backticks. The preview of this message is showing it without "`" either side of the command for some reason.

As long as the python script will run from the cli by name rather than python pythonprog.py this works within the script. If you need more than one argument just use a space between each one within the quotes.

The variable in the for loop is an integer sequence, and so eventually you do this:

> y=as.integer(60000)*as.integer(60000)
Warning message:
In as.integer(60000) * as.integer(60000) : NAs produced by integer overflow

whereas in the while loop you are creating a floating point number.

Its also the reason these things are different:

> seq(0,2,1)
[1] 0 1 2
> seq(0,2)
[1] 0 1 2

Don't believe me?

> identical(seq(0,2),seq(0,2,1))
[1] FALSE

because:

> is.integer(seq(0,2))
[1] TRUE
> is.integer(seq(0,2,1))
[1] FALSE

This is one way to do it:

string = "this is a string"
ssplit = string.split()
for word in ssplit:
    print (word)

Output:

this
is
a
string

I had the same error with Symfony on wamp and PHP 7.0.0.

symptoms

None of the JS and CSS dependencies was loaded on the "dev" environnement, with error Failed to load resource: net::ERR_CONNECTION_RESET

solution

It's effectively a certificate problem in php.ini. You need to set the property curl.cainfo to a valid certificate in the line :

curl.cainfo = C:\your\wamp\path\bin\cacert\cacert.pem

Try something like this:

int main()
{
    printf("%x %x %x %x %x %x %x %x\n",
        0xC0, 0xC0, 0x61, 0x62, 0x63, 0x31, 0x32, 0x33);
}

Which produces this:

$ ./foo 
c0 c0 61 62 63 31 32 33

Use moment js for any date operation.

https://momentjs.com/

console.log(moment("Sunday, February 28, 2010").format('MM/DD/YYYY'));

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>

Another option that I recently stumbled on is this:

    {
        echo "First error line"
        echo "Second error line"
        echo "Third error line"
    } >&2

This uses only Bash built-ins while making multi-line error output less error prone (since you don't have to remember to add &>2 to every line).

I'm not sure about what you mean by "I have no access to image" But if you have access to parent div you can do the following:

Firs give id or class to your div:

<div class="parent">
   <img src="http://someimage.jpg">
</div>

Than add this to your css:

.parent {
   width: 42px; /* I took the width from your post and placed it in css */
   height: 42px;
}

/* This will style any <img> element in .parent div */
.parent img {
   height: 100%;
   width: 100%;
}

I took some inspiration from other answers and made the inputs have automatic sanitation. I hope this works well as an improvement over other answers.

//use best practices by labeling your constants.
let MS_PER_SEC = 1000
  , SEC_PER_HR = 60 * 60
  , HR_PER_DAY = 24
  , MS_PER_DAY = MS_PER_SEC * SEC_PER_HR * HR_PER_DAY
;

//let's assume we get Date objects as arguments, otherwise return 0.
function dateDiffInDays(date1, date2) {
    if (!date1 || !date2) {
      return 0;
    }
    return Math.round((date2.getTime() - date1.getTime()) / MS_PER_DAY);
}

// new Date("dateString") is browser-dependent and discouraged, so we'll write

function parseDate(str) {
    if (str && str.length > 7 && str.length < 11) {
      let mdy = str.split('/');
      return new Date(mdy[2], mdy[0]-1, mdy[1]);
    }
    return null;
}

function calcInputs() {
  let date1 = document.getElementById("date1")
    , date2 = document.getElementById("date2")
    , resultSpan = document.getElementById("result")
  ;
  if (date1 && date2 && resultSpan) {
    //remove non-date characters
    let date1Val = date1.value.replace(/[^\d\/]/g,'')
      , date2Val = date2.value.replace(/[^\d\/]/g,'')
      , result = dateDiffInDays(parseDate(date1Val), parseDate(date2Val))
    ;
    date1.value = date1Val;
    date2.value = date2Val;
    resultSpan.innerHTML = result + " days";
  }
}
window.onload = function() { calcInputs(); };

//some code examples
console.log(dateDiffInDays(parseDate("1/15/2019"), parseDate("1/30/2019")));
console.log(dateDiffInDays(parseDate("1/15/2019"), parseDate("2/30/2019")));
console.log(dateDiffInDays(parseDate("1/15/2000"), parseDate("1/15/2019")));

<input id="date1" type="text" value="1/1/2000" size="6" onkeyup="calcInputs();" />
<input id="date2" type="text" value="1/1/2019" size="6" onkeyup="calcInputs();"/>
Result: <span id="result"></span>

I found it's better to set the width and height to 0px. Otherwise, IE10 ignores the padding defined on the field -- padding-right -- which was intended to keep the text from typing over the 'X' icon that I overlayed on the input field. I'm guessing that IE10 is internally applying the padding-right of the input to the ::--ms-clear pseudo element, and hiding the pseudo element does not restore the padding-right value to the input.

This worked better for me:

.someinput::-ms-clear {
  width : 0;
  height: 0;
}

First thing, you should not do any DOM manipulation in controller function. Instead, you should use directives for this purpose. directive's link function is available for those kind of stuff only.

AngularJS Docs : Creating a Directive that Manipulates the DOM

app.directive('buttonDirective', function($timeout) {
  return {
    scope: {
       change: '&'
    },
    link: function(scope, element, attrs) {
      element.bind('click', function() {
        $timeout(function() {
          // triggering callback
          scope.change();
        });
      });
    }
  };
});

change callback can be used as listener for click event.

Tested only on Visual Studio 2010.

Place your cursor within the (), press Ctrl+K, then P.

Now navigate by pressing the  ?  / ?   arrow keys.

You have a lot of pointless jQuery in there, but the $compile service is actually super simple in this case:

.directive( 'test', function ( $compile ) {
  return {

You'll notice I refactored your directive too in order to follow some best practices. Let me know if you have questions about any of those.

if you know what unknown is,

you can do something like

myArray = zeros(2,2);
for i: 1:unknown
  myArray(:,i) = zeros(x,y);
end

However it has been a while since I last used matlab. so this page might shed some light on the matter :

Compared to Python, IPython (created by Fernando Perez in 2001) can do every thing what python can do. Ipython provides even extra features like tab-completion, testing, debugging, system calls and many other features. You can think IPython as a powerful interface to the Python language.

You can install Ipython using pip - pip install ipython

You can run Ipython by typing ipython in your terminal window.

import csv
reader = csv.reader(open('filename.csv', 'r'))
d = {}
for row in reader:
   k, v = row
   d[k] = v

The sequel gem adds an update_or_create method which seems to do what you're looking for.

if you have a problem on groupActivity dont use this. PARENT is a static from the Parent ActivityGroup.

final AlertDialog.Builder builder = new AlertDialog.Builder(GroupActivityParent.PARENT);

instead of

final AlertDialog.Builder builder = new AlertDialog.Builder(getParent());

It seems your @ComponentScan annotation is not set properly. Try :

@ComponentScan(basePackages = {"com.pharmacy"})

Actually you do not need the component scan if you have your main class at the top of the structure, for example directly under com.pharmacy package.

Also, you don't need both

@SpringBootApplication
@EnableAutoConfiguration

The @SpringBootApplication annotation includes @EnableAutoConfiguration by default.

The context lets you provide arguments at call-time, allowing easy customization of generic pre-built helper functions.

some examples:

// stock footage:
function addTo(x){ "use strict"; return x + this; }
function pluck(x){ "use strict"; return x[this]; }
function lt(x){ "use strict"; return x < this; }

// production:
var r = [1,2,3,4,5,6,7,8,9];
var words = "a man a plan a canal panama".split(" ");

// filtering numbers:
_.filter(r, lt, 5); // elements less than 5
_.filter(r, lt, 3); // elements less than 3

// add 100 to the elements:
_.map(r, addTo, 100);

// encode eggy peggy:
_.map(words, addTo, "egg").join(" ");

// get length of words:
_.map(words, pluck, "length"); 

// find words starting with "e" or sooner:
_.filter(words, lt, "e"); 

// find all words with 3 or more chars:
_.filter(words, pluck, 2); 

Even from the limited examples, you can see how powerful an "extra argument" can be for creating re-usable code. Instead of making a different callback function for each situation, you can usually adapt a low-level helper. The goal is to have your custom logic bundling a verb and two nouns, with minimal boilerplate.

Admittedly, arrow functions have eliminated a lot of the "code golf" advantages of generic pure functions, but the semantic and consistency advantages remain.

I always add "use strict" to helpers to provide native [].map() compatibility when passing primitives. Otherwise, they are coerced into objects, which usually still works, but it's faster and safer to be type-specific.

as of 2017 this is more responsive and worked for me. This is for putting text inside vs over, like a badge. instead of the number 8, I had a variable to pull data from a database.

this code started with Kailas's answer up above

https://jsfiddle.net/jim54729/memmu2wb/3/

My HTML

<div class="containerBox">
  <img class="img-responsive"    src="https://s20.postimg.org/huun8e6fh/Gold_Ring.png">
  <div class='text-box'>
   <p class='dataNumber'> 8 </p>
  </div>
</div>

and my css:

.containerBox {
  position: relative;
  display: inline-block;
}

.text-box {
  position: absolute;
  height: 30%;
  text-align: center;
  width: 100%;
  margin: auto;
  top: 0;
  bottom: 0;
  right: 0;
  left: 0;
  font-size: 30px;
}

.img-responsive {
  display: block;
  max-width: 100%;
  height: 120px;
  margin: auto;
  padding: auto;
}

.dataNumber {
  margin-top: auto;
}

This is much easier:

<textarea onKeyPress="return ( this.value.length < 1000 );"></textarea>

There are no JS callbacks for CSS assets.

If you have BS4 another option could be:

.dropdown-item { 
  width: max-content !important;
}

.dropdown-menu {

    max-height: max-content;
    max-width: max-content;
}

Add a connection string in the root web.config file of 'container' MVC project that references the class library as following:

 <connectionStrings>

  <add name="MyEntities" connectionString="complete connection string here" providerName="System.Data.SqlClient" />

  </connectionStrings>

If you do not want to use "MyEntities" as connection name then change it as you wish but make the following change in your MyEntities DbContext class:

MyEntities: DbContext
 {
   public MyEntities():base("Name-Of-connection-string-you wish to connect"){ }
 }

Reason for this error is, If we will not specify the name of connection string Or connect string in derived class of DbConext(In your case it is MyEntities) then DbContext will automatically search for a connection string in root web.config file whoes name is same as derived class name (In your case it is My Entities).

You can use a WScript object and call the Sleep method on it:

Set WScript = CreateObject("WScript.Shell")
WScript.Sleep 2000 'Sleeps for 2 seconds

Another option is to import and use the WinAPI function directly (only works in VBA, thanks @Helen):

Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sleep 2000

GitHub now supports closing a pull request

Basically, you need to do the following steps:

1. Visit the pull request page
2. Click on the pull request
3. Click the "close pull request" button

Example (button on the very bottom):

This way the pull request gets closed (and ignored), without merging it.

Use the Desktop#browse(URI) method. It opens a URI in the user's default browser.

public static boolean openWebpage(URI uri) {
    Desktop desktop = Desktop.isDesktopSupported() ? Desktop.getDesktop() : null;
    if (desktop != null && desktop.isSupported(Desktop.Action.BROWSE)) {
        try {
            desktop.browse(uri);
            return true;
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    return false;
}

public static boolean openWebpage(URL url) {
    try {
        return openWebpage(url.toURI());
    } catch (URISyntaxException e) {
        e.printStackTrace();
    }
    return false;
}

I got this error because of a missing return statement.

Not sure what your desired output is, but if you're using list comprehension, the order follows the order of nested loops, which you have backwards. So I got the what I think you want with:

[float(y) for x in l for y in x]

The principle is: use the same order you'd use in writing it out as nested for loops.

a tiny improvement for the answer from interjay, to make the result as a flatten list.

>>> list3 = [zip(x,list2) for x in itertools.permutations(list1,len(list2))]
>>> import itertools
>>> chain = itertools.chain(*list3)
>>> list4 = list(chain)
[('a', 1), ('b', 2), ('a', 1), ('c', 2), ('b', 1), ('a', 2), ('b', 1), ('c', 2), ('c', 1), ('a', 2), ('c', 1), ('b', 2)]

You might not have the ability to install Expect on the target server. This is often the case when one writes, say, a Jenkins job.

If so, I would consider something like the answer to the following on askubuntu.com:

https://askubuntu.com/questions/338857/automatically-enter-input-in-command-line

printf 'y\nyes\nno\nmaybe\n' | ./script_that_needs_user_input

Note that in some rare cases the command does not require the user to press enter after the character. in that case leave the newlines out:

printf 'yyy' | ./script_that_needs_user_input

For sake of completeness you can also use a here document:

./script_that_needs_user_input << EOF
y
y
y
EOF

Or if your shell supports it a here string:

./script <<< "y
y
y
"

Or you can create a file with one input per line:

./script < inputfile

Again, all credit for this answer goes to the author of the answer on askubuntu.com, lesmana.

uncomment "curl=cainfo" in the php.ini document This helped me when installing Prestashop when all other methods still did not work.

The urlArgs solution has problems. Unfortunately you cannot control all proxy servers that might be between you and your user's web browser. Some of these proxy servers can be unfortunately configured to ignore URL parameters when caching files. If this happens, the wrong version of your JS file will be delivered to your user.

I finally gave up and implemented my own fix directly into require.js. If you are willing to modify your version of the requirejs library, this solution might work for you.

You can see the patch here:

https://github.com/jbcpollak/requirejs/commit/589ee0cdfe6f719cd761eee631ce68eee09a5a67

Once added, you can do something like this in your require config:

var require = {
    baseUrl: "/scripts/",
    cacheSuffix: ".buildNumber"
}

Use your build system or server environment to replace buildNumber with a revision id / software version / favorite color.

Using require like this:

require(["myModule"], function() {
    // no-op;
});

Will cause require to request this file:

http://yourserver.com/scripts/myModule.buildNumber.js

On our server environment, we use url rewrite rules to strip out the buildNumber, and serve the correct JS file. This way we don't actually have to worry about renaming all of our JS files.

The patch will ignore any script that specifies a protocol, and it will not affect any non-JS files.

This works well for my environment, but I realize some users would prefer a prefix rather than a suffix, it should be easy to modify my commit to suit your needs.

Update:

In the pull request discussion, the requirejs author suggest this might work as a solution to prefix the revision number:

var require = {
    baseUrl: "/scripts/buildNumber."
};

I have not tried this, but the implication is that this would request the following URL:

http://yourserver.com/scripts/buildNumber.myModule.js

Which might work very well for many people who can use a prefix.

Here's a quick and dirty json pickle alternative

import json

class User:
    def __init__(self, name, username):
        self.name = name
        self.username = username

    def to_json(self):
        return json.dumps(self.__dict__)

    @classmethod
    def from_json(cls, json_str):
        json_dict = json.loads(json_str)
        return cls(**json_dict)

# example usage
User("tbrown", "Tom Brown").to_json()
User.from_json(User("tbrown", "Tom Brown").to_json()).to_json()

The answers here are not actually completely correct. Close, but there's an edge case.

The difference is that $('body') actually selects the element by the tag name, whereas document.body references the direct object on the document.

That means if you (or a rogue script) overwrites the document.body element (shame!) $('body') will still work, but $(document.body) will not. So by definition they're not equivalent.

I'd venture to guess there are other edge cases (such as globally id'ed elements in IE) that would also trigger what amounts to an overwritten body element on the document object, and the same situation would apply.

More Suggestive answer supporting rmaddy's answer as our primary purpose is to delete unnecessary file and folder:

1. Delete this folder after every few days interval. Most of the time, it occupy huge space!

     ~/Library/Developer/Xcode/DerivedData
   

2. All your targets are kept in the archived form in Archives folder. Before you decide to delete contents of this folder, here is a warning - if you want to be able to debug deployed versions of your App, you shouldn’t delete the archives. Xcode will manage of archives and creates new file when new build is archived.

     ~/Library/Developer/Xcode/Archives
   

3. iOS Device Support folder creates a subfolder with the device version as an identifier when you attach the device. Most of the time it’s just old stuff. Keep the latest version and rest of them can be deleted (if you don’t have an app that runs on 5.1.1, there’s no reason to keep the 5.1.1 directory/directories). If you really don't need these, delete. But we should keep a few although we test app from device mostly.

   ~/Library/Developer/Xcode/iOS DeviceSupport
   

4. Core Simulator folder is familiar for many Xcode users. It’s simulator’s territory; that's where it stores app data. It’s obvious that you can toss the older version simulator folder/folders if you no longer support your apps for those versions. As it is user data, no big issue if you delete it completely but it’s safer to use ‘Reset Content and Settings’ option from the menu to delete all of your app data in a Simulator.

     ~/Library/Developer/CoreSimulator 
   

(Here's a handy shell command for step 5: xcrun simctl delete unavailable )

5. Caches are always safe to delete since they will be recreated as necessary. This isn’t a directory; it’s a file of kind Xcode Project. Delete away!

   ~/Library/Caches/com.apple.dt.Xcode
   

6. Additionally, Apple iOS device automatically syncs specific files and settings to your Mac every time they are connected to your Mac machine. To be on safe side, it’s wise to use Devices pane of iTunes preferences to delete older backups; you should be retaining your most recent back-ups off course.

    ~/Library/Application Support/MobileSync/Backup

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

Hi if you are going to subtract only Integer value from DateTime then you have to write code like this

DateTime.Now.AddHours(-2)

Here I am subtracting 2 hours from the current date and time

The ssh daemon (sshd), which runs server-side, closes the connection from the server-side if the client goes silent (i.e., does not send information). To prevent connection loss, instruct the ssh client to send a sign-of-life signal to the server once in a while.

The configuration for this is in the file $HOME/.ssh/config, create the file if it does not exist (the config file must not be world-readable, so run chmod 600 ~/.ssh/config after creating the file). To send the signal every e.g. four minutes (240 seconds) to the remote host, put the following in that configuration file:

Host remotehost
    HostName remotehost.com
    ServerAliveInterval 240

To enable sending a keep-alive signal for all hosts, place the following contents in the configuration file:

Host *
    ServerAliveInterval 240

You need to specify both source and destination, and if you want to copy directories you should look at the -r option.

So to recursively copy /home/user/whatever from remote server to your current directory:

scp -pr user@remoteserver:whatever .

Checkout this, This is from PHP MANUAL, This may help you.

If you're using PHP_CLI SAPI and getting error "Maximum execution time of N seconds exceeded" where N is an integer value, try to call set_time_limit(0) every M seconds or every iteration. For example:

<?php

require_once('db.php');

$stmt = $db->query($sql);

while ($row = $stmt->fetchRow()) {
    set_time_limit(0);
    // your code here
}

?>

??! is a trigraph that translates to |. So it says:

!ErrorHasOccured() || HandleError();

which, due to short circuiting, is equivalent to:

if (ErrorHasOccured())
    HandleError();

Guru of the Week (deals with C++ but relevant here), where I picked this up.

Possible origin of trigraphs or as @DwB points out in the comments it's more likely due to EBCDIC being difficult (again). This discussion on the IBM developerworks board seems to support that theory.

From ISO/IEC 9899:1999 §5.2.1.1, footnote 12 (h/t @Random832):

The trigraph sequences enable the input of characters that are not defined in the Invariant Code Set as described in ISO/IEC 646, which is a subset of the seven-bit US ASCII code set.

I think a better way to do it is to merge 2 things:

1. make a bitmap of the layout, as shown here.

2. make a rounded drawable from the bitmap, as shown here

3. set the drawable on an imageView.

This will handle cases that other solutions have failed to solve, such as having content that has corners.

I think it's also a bit more GPU-friendly, as it shows a single layer instead of 2 .

The only better way is to make a totally customized view, but that's a lot of code and might take a lot of time. I think that what I suggested here is the best of both worlds.

Here's a snippet of how it can be done:

RoundedCornersDrawable.java

/**
 * shows a bitmap as if it had rounded corners. based on :
 * http://rahulswackyworld.blogspot.co.il/2013/04/android-drawables-with-rounded_7.html
 * easy alternative from support library: RoundedBitmapDrawableFactory.create( ...) ; 
 */
public class RoundedCornersDrawable extends BitmapDrawable {

    private final BitmapShader bitmapShader;
    private final Paint p;
    private final RectF rect;
    private final float borderRadius;

    public RoundedCornersDrawable(final Resources resources, final Bitmap bitmap, final float borderRadius) {
        super(resources, bitmap);
        bitmapShader = new BitmapShader(getBitmap(), Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
        final Bitmap b = getBitmap();
        p = getPaint();
        p.setAntiAlias(true);
        p.setShader(bitmapShader);
        final int w = b.getWidth(), h = b.getHeight();
        rect = new RectF(0, 0, w, h);
        this.borderRadius = borderRadius < 0 ? 0.15f * Math.min(w, h) : borderRadius;
    }

    @Override
    public void draw(final Canvas canvas) {
        canvas.drawRoundRect(rect, borderRadius, borderRadius, p);
    }
}

CustomView.java

public class CustomView extends ImageView {
    private View mMainContainer;
    private boolean mIsDirty=false;

    // TODO for each change of views/content, set mIsDirty to true and call invalidate

    @Override
    protected void onDraw(final Canvas canvas) {
        if (mIsDirty) {
            mIsDirty = false;
            drawContent();
            return;
        }
        super.onDraw(canvas);
    }

    /**
     * draws the view's content to a bitmap. code based on :
     * http://nadavfima.com/android-snippet-inflate-a-layout-draw-to-a-bitmap/
     */
    public static Bitmap drawToBitmap(final View viewToDrawFrom, final int width, final int height) {
        // Create a new bitmap and a new canvas using that bitmap
        final Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        final Canvas canvas = new Canvas(bmp);
        viewToDrawFrom.setDrawingCacheEnabled(true);
        // Supply measurements
        viewToDrawFrom.measure(MeasureSpec.makeMeasureSpec(canvas.getWidth(), MeasureSpec.EXACTLY),
                MeasureSpec.makeMeasureSpec(canvas.getHeight(), MeasureSpec.EXACTLY));
        // Apply the measures so the layout would resize before drawing.
        viewToDrawFrom.layout(0, 0, viewToDrawFrom.getMeasuredWidth(), viewToDrawFrom.getMeasuredHeight());
        // and now the bmp object will actually contain the requested layout
        canvas.drawBitmap(viewToDrawFrom.getDrawingCache(), 0, 0, new Paint());
        return bmp;
    }

    private void drawContent() {
        if (getMeasuredWidth() <= 0 || getMeasuredHeight() <= 0)
            return;
        final Bitmap bitmap = drawToBitmap(mMainContainer, getMeasuredWidth(), getMeasuredHeight());
        final RoundedCornersDrawable drawable = new RoundedCornersDrawable(getResources(), bitmap, 15);
        setImageDrawable(drawable);
    }

}

EDIT: found a nice alternative, based on "RoundKornersLayouts" library. Have a class that will be used for all of the layout classes you wish to extend, to be rounded:

//based on https://github.com/JcMinarro/RoundKornerLayouts
class CanvasRounder(cornerRadius: Float, cornerStrokeColor: Int = 0, cornerStrokeWidth: Float = 0F) {
    private val path = android.graphics.Path()
    private lateinit var rectF: RectF
    private var strokePaint: Paint?
    var cornerRadius: Float = cornerRadius
        set(value) {
            field = value
            resetPath()
        }

    init {
        if (cornerStrokeWidth <= 0)
            strokePaint = null
        else {
            strokePaint = Paint()
            strokePaint!!.style = Paint.Style.STROKE
            strokePaint!!.isAntiAlias = true
            strokePaint!!.color = cornerStrokeColor
            strokePaint!!.strokeWidth = cornerStrokeWidth
        }
    }

    fun round(canvas: Canvas, drawFunction: (Canvas) -> Unit) {
        val save = canvas.save()
        canvas.clipPath(path)
        drawFunction(canvas)
        if (strokePaint != null)
            canvas.drawRoundRect(rectF, cornerRadius, cornerRadius, strokePaint)
        canvas.restoreToCount(save)
    }

    fun updateSize(currentWidth: Int, currentHeight: Int) {
        rectF = android.graphics.RectF(0f, 0f, currentWidth.toFloat(), currentHeight.toFloat())
        resetPath()
    }

    private fun resetPath() {
        path.reset()
        path.addRoundRect(rectF, cornerRadius, cornerRadius, Path.Direction.CW)
        path.close()
    }

}

Then, in each of your customized layout classes, add code similar to this one:

class RoundedConstraintLayout : ConstraintLayout {
    private lateinit var canvasRounder: CanvasRounder

    constructor(context: Context) : super(context) {
        init(context, null, 0)
    }

    constructor(context: Context, attrs: AttributeSet) : super(context, attrs) {
        init(context, attrs, 0)
    }

    constructor(context: Context, attrs: AttributeSet, defStyle: Int) : super(context, attrs, defStyle) {
        init(context, attrs, defStyle)
    }

    private fun init(context: Context, attrs: AttributeSet?, defStyle: Int) {
        val array = context.obtainStyledAttributes(attrs, R.styleable.RoundedCornersView, 0, 0)
        val cornerRadius = array.getDimension(R.styleable.RoundedCornersView_corner_radius, 0f)
        val cornerStrokeColor = array.getColor(R.styleable.RoundedCornersView_corner_stroke_color, 0)
        val cornerStrokeWidth = array.getDimension(R.styleable.RoundedCornersView_corner_stroke_width, 0f)
        array.recycle()
        canvasRounder = CanvasRounder(cornerRadius,cornerStrokeColor,cornerStrokeWidth)
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR2) {
            setLayerType(FrameLayout.LAYER_TYPE_SOFTWARE, null)
        }
    }

    override fun onSizeChanged(currentWidth: Int, currentHeight: Int, oldWidth: Int, oldheight: Int) {
        super.onSizeChanged(currentWidth, currentHeight, oldWidth, oldheight)
        canvasRounder.updateSize(currentWidth, currentHeight)
    }

    override fun draw(canvas: Canvas) = canvasRounder.round(canvas) { super.draw(canvas) }

    override fun dispatchDraw(canvas: Canvas) = canvasRounder.round(canvas) { super.dispatchDraw(canvas) }

}

If you wish to support attributes, use this as written on the library:

<resources>
  <declare-styleable name="RoundedCornersView">
      <attr name="corner_radius" format="dimension"/>
      <attr name="corner_stroke_width" format="dimension"/>
      <attr name="corner_stroke_color" format="color"/>
  </declare-styleable>
</resources>

Another alternative, which might be easier for most uses: use MaterialCardView . It allows customizing the rounded corners, stroke color and width, and elevation.

Example:

<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:clipChildren="false" android:clipToPadding="false"
    tools:context=".MainActivity">

    <com.google.android.material.card.MaterialCardView
        android:layout_width="100dp" android:layout_height="100dp" android:layout_gravity="center"
        app:cardCornerRadius="8dp" app:cardElevation="8dp" app:strokeColor="#f00" app:strokeWidth="2dp">

        <ImageView
            android:layout_width="match_parent" android:layout_height="match_parent" android:background="#0f0"/>

    </com.google.android.material.card.MaterialCardView>

</FrameLayout>

And the result:

Do note that there is a slight artifacts issue at the edges of the stroke (leaves some pixels of the content there), if you use it. You can notice it if you zoom in. I've reported about this issue here.

EDIT: seems to be fixed, but not on the IDE. Reported here.

I had the same issue, to resolve it I added the following line to my.ini

innodb_force_recovery = 1

Well, you can stick one or more "soft hyphens" (­) in your long unbroken strings. I doubt that old IE versions deal with that correctly, but what it's supposed to do is tell the browser about allowable word breaks that it can use if it has to.

Now, how exactly would you pick where to stuff those characters? That depends on the actual string and what it means, I guess.

I'm afraid I don't think there's a shortcut to do this - if only someone would write a linq wrapper for VB6!

You could write a function that does it by looping through the array and checking each entry - I don't think you'll get cleaner than that.

There's an example article that provides some details here: http://www.vb6.us/tutorials/searching-arrays-visual-basic-6

A Web Reference allows you to communicate with any service based on any technology that implements the WS-I Basic Profile 1.1, and exposes the relevant metadata as WSDL. Internally, it uses the ASMX communication stack on the client's side.

A Service Reference allows you to communicate with any service based on any technology that implements any of the many protocols supported by WCF (including but not limited to WS-I Basic Profile). Internally, it uses the WCF communication stack on the client side.

Note that both these definitions are quite wide, and both include services not written in .NET.

It is perfectly possible (though not recommended) to add a Web Reference that points to a WCF service, as long as the WCF endpoint uses basicHttpBinding or some compatible custom variant.

It is also possible to add a Service Reference that points to an ASMX service. When writing new code, you should always use a Service Reference simply because it is more flexible and future-proof.

Look at the following:

echo "ls -l" | at 07:00

This code line executes "ls -l" at a specific time. This is an example of executing something (a command in my example) at a specific time. "at" is the command you were really looking for. You can read the specifications here:

http://manpages.ubuntu.com/manpages/precise/en/man1/at.1posix.html http://manpages.ubuntu.com/manpages/xenial/man1/at.1posix.html

Hope it helps!

Since awk and perl are closely related...

Perl equivalents of @Dennis's awk solutions:

To print the second line:
perl -ne 'print if $. == 2' file

To print the second field:
perl -lane 'print $F[1]' file

To print the third field of the fifth line:
perl -lane 'print $F[2] if $. == 5' file

Perl equivalent of @Glenn's solution:

Print the j'th field of the i'th line

perl -lanse 'print $F[$j-1] if $. == $i' -- -i=5 -j=3 file

Perl equivalents of @Hai's solutions:

if you are looking for second columns that contains abc:

perl -lane 'print if $F[1] =~ /abc/' foo

... and if you want to print only a particular column:

perl -lane 'print $F[2] if $F[1] =~ /abc/' foo

... and for a particular line number:

perl -lane 'print $F[2] if $F[1] =~ /abc/ && $. == 5' foo

-l removes newlines, and adds them back in when printing
-a autosplits the input line into array @F, using whitespace as the delimiter
-n loop over each line of the input file
-e execute the code within quotes
$F[1] is the second element of the array, since Perl starts at 0
$. is the line number

We had the same problem on a CentOS7 machine. Disabling the VERIFYHOST VERIFYPEER did not solve the problem, we did not have the cURL error anymore but the response still was invalid. Doing a wget to the same link as the cURL was doing also resulted in a certificate error.

-> Our solution also was to reboot the VPS, this solved it and we were able to complete the request again.

For us this seemed to be a memory corruption problem. Rebooting the VPS reloaded the libary in the memory again and now it works. So if the above solution from @clover does not work try to reboot your machine.

sed

You can use sed to parse the ini configuration file, especially when you've section names like:

# last modified 1 April 2001 by John Doe
[owner]
name=John Doe
organization=Acme Widgets Inc.

[database]
# use IP address in case network name resolution is not working
server=192.0.2.62
port=143
file=payroll.dat

so you can use the following sed script to parse above data:

# Configuration bindings found outside any section are given to
# to the default section.
1 {
  x
  s/^/default/
  x
}

# Lines starting with a #-character are comments.
/#/n

# Sections are unpacked and stored in the hold space.
/\[/ {
  s/\[\(.*\)\]/\1/
  x
  b
}

# Bindings are unpacked and decorated with the section
# they belong to, before being printed.
/=/ {
  s/^[[:space:]]*//
  s/[[:space:]]*=[[:space:]]*/|/
  G
  s/\(.*\)\n\(.*\)/\2|\1/
  p
}

this will convert the ini data into this flat format:

owner|name|John Doe
owner|organization|Acme Widgets Inc.
database|server|192.0.2.62
database|port|143
database|file|payroll.dat

so it'll be easier to parse using sed, awk or read by having section names in every line.

Alternatively, you can use this project: chilladx/config-parser, a configuration parser using sed.

A mutex is a mutual exclusion object, similar to a semaphore but that only allows one locker at a time and whose ownership restrictions may be more stringent than a semaphore.

It can be thought of as equivalent to a normal counting semaphore (with a count of one) and the requirement that it can only be released by the same thread that locked it^(a).

A semaphore, on the other hand, has an arbitrary count and can be locked by that many lockers concurrently. And it may not have a requirement that it be released by the same thread that claimed it (but, if not, you have to carefully track who currently has responsibility for it, much like allocated memory).

So, if you have a number of instances of a resource (say three tape drives), you could use a semaphore with a count of 3. Note that this doesn't tell you which of those tape drives you have, just that you have a certain number.

Also with semaphores, it's possible for a single locker to lock multiple instances of a resource, such as for a tape-to-tape copy. If you have one resource (say a memory location that you don't want to corrupt), a mutex is more suitable.

Equivalent operations are:

Counting semaphore          Mutual exclusion semaphore
--------------------------  --------------------------
  Claim/decrease (P)                  Lock
  Release/increase (V)                Unlock

Aside: in case you've ever wondered at the bizarre letters used for claiming and releasing semaphores, it's because the inventor was Dutch. Probeer te verlagen means to try and decrease while verhogen means to increase.

^(a) ... or it can be thought of as something totally distinct from a semaphore, which may be safer given their almost-always-different uses.

The document.ready event occurs when the HTML document has been loaded, and the window.onload event occurs always later, when all content (images, etc) has been loaded.

You can use the document.ready event if you want to intervene "early" in the rendering process, without waiting for the images to load. If you need the images (or any other "content") ready before your script "does something", you need to wait until window.onload.

For instance, if you are implementing a "Slide Show" pattern, and you need to perform calculations based on image sizes, you may want to wait until window.onload. Otherwise, you might experience some random problems, depending on how fast the images will get loaded. Your script would be running concurrently with the thread that loads images. If your script is long enough, or the server is fast enough, you may not notice a problem, if images happen to arrive in time. But the safest practice would be allowing for images to get loaded.

document.ready could be a nice event for you to show some "loading..." sign to users, and upon window.onload, you can complete any scripting that needed resources loaded, and then finally remove the "Loading..." sign.

Examples :-

// document ready events
$(document).ready(function(){
     alert("document is ready..");
})

// using JQuery
$(function(){
   alert("document is ready..");
})

// window on load event
function myFunction(){
  alert("window is loaded..");
}
window.onload = myFunction;

You have to loop over the input array and add rules for each input as described here: Loop Over Rules

Here is a some code for ya:

$input = Request::all();
$rules = [];

foreach($input['name'] as $key => $val)
{
    $rules['name.'.$key] = 'required|distinct|min:3';
}

$rules['amount'] = 'required|integer|min:1';
$rules['description'] = 'required|string';

$validator = Validator::make($input, $rules);

//Now check validation:
if ($validator->fails()) 
{ 
  /* do something */ 
}

Not sure if this works for cells with functions but I found this code elsewhere for single cell entries and modified it for my use. If done properly, you do not need to worry about entering a function in a cell or the file changing the dates to that day's date every time it is opened.

• open Excel
• press "Alt+F11"
• Double-click on the worksheet that you want to apply the change to (listed on the left)
• copy/paste the code below
• adjust the Range(:) input to correspond to the column you will update
• adjust the Offset(0,_) input to correspond to the column where you would like the date displayed (in the version below I am making updates to column D and I want the date displayed in column F, hence the input entry of "2" for 2 columns over from column D)
• hit save
• repeat steps above if there are other worksheets in your workbook that need the same code
• you may have to change the number format of the column displaying the date to "General" and increase the column's width if it is displaying "####" after you make an updated entry

Copy/Paste Code below:

Private Sub Worksheet_Change(ByVal Target As Range)

If Intersect(Target, Range("D:D")) Is Nothing Then Exit Sub
Target.Offset(0, 2) = Date

End Sub

Good luck...

While seleted answer was right time ago, and then noelicus gave correct update regarding v110_xp platform toolset, there is still one more issue that could produse this behaviour.

A note about issue was already posted by mahesh in his comment, and I would like to highlight this as I have spend couple of days struggling and then find it by myself.

So, if you have a blank in "Configuration Properties -> Linker -> System -> Subsystem" you will still get the "not valid Win32 app" error on XP and Win2003 while on Win7 it works without this annoying error. The error gone as soon as I've put subsystem:console.

If I understand correctly, you have a vector containing variable names and would like loop through each name and sort your data frame by them. If so, this example should illustrate a solution for you. The primary issue in yours (the full example isn't complete so I"m not sure what else you may be missing) is that it should be order(Q1_R1000[,parameter[X]]) instead of order(Q1_R1000$parameter[X]), since parameter is an external object that contains a variable name opposed to a direct column of your data frame (which when the $ would be appropriate).

set.seed(1)
dat <- data.frame(var1=round(rnorm(10)),
                   var2=round(rnorm(10)),
                   var3=round(rnorm(10)))
param <- paste0("var",1:3)
dat
#   var1 var2 var3
#1    -1    2    1
#2     0    0    1
#3    -1   -1    0
#4     2   -2   -2
#5     0    1    1
#6    -1    0    0
#7     0    0    0
#8     1    1   -1
#9     1    1    0
#10    0    1    0

for(p in rev(param)){
   dat <- dat[order(dat[,p]),]
 }
dat
#   var1 var2 var3
#3    -1   -1    0
#6    -1    0    0
#1    -1    2    1
#7     0    0    0
#2     0    0    1
#10    0    1    0
#5     0    1    1
#8     1    1   -1
#9     1    1    0
#4     2   -2   -2

1. Click File on the ribbon menu, and then click on Options.

2. Click Advanced, and then under When calculating this workbook, select the Set precision as displayed check box, and then click OK.

3. Click OK.

4. In the worksheet, select the cells that you want to format.

5. On the Home tab, click the Dialog Box Launcher Button image next to Number.

6. In the Category box, click Number.

7. In the Decimal places box, enter the number of decimal places that you want to display.

var value = (uint)Enum.Parse(typeof(basekey), "HKEY_LOCAL_MACHINE", true);

This code snippet illustrates obtaining an enum value from a string. To convert from a string, you need to use the static Enum.Parse() method, which takes 3 parameters. The first is the type of enum you want to consider. The syntax is the keyword typeof() followed by the name of the enum class in brackets. The second parameter is the string to be converted, and the third parameter is a bool indicating whether you should ignore case while doing the conversion.

Finally, note that Enum.Parse() actually returns an object reference, that means you need to explicitly convert this to the required enum type(string,int etc).

Thank you.

This question was answered well at Can you encode CR/LF in into CSV files?.

Consider also reverse engineering multiple lines in Excel. To embed a newline in an Excel cell, press Alt+Enter. Then save the file as a .csv. You'll see that the double-quotes start on one line and each new line in the file is considered an embedded newline in the cell.

This may be the good solution for you: change the code like this very little change

.box{
    position: relative; 
}
.box:hover .hidden{
    opacity: 1;
    width:500px;
}
.box .hidden{
    background: yellow;
    height: 334px; 
    position: absolute;
    top: 0;
    left: 0;
    width: 0;
    opacity: 0;
    transition: all 1s ease;
}

See demo here

window.location.href = window.location.href

for detail info, let's say the code below will make a div aligned center:

margin-left: auto;
margin-right: auto;

or simply use:

margin: 0 auto;

but bear in mind, the above CSS code only works when you specify a fixed width (not 100%) on your html element. so the complete solution for your issue would be:

.your-inner-div {
      margin: 0 auto;
      width: 900px;
}

These are positional arguments of the script.

Executing

./script.sh Hello World

Will make

$0 = ./script.sh
$1 = Hello
$2 = World

Note

If you execute ./script.sh, $0 will give output ./script.sh but if you execute it with bash script.sh it will give output script.sh.

A sample code that works for me on Windows:

import requests

with open('pic1.jpg', 'wb') as handle:
        response = requests.get(pic_url, stream=True)

        if not response.ok:
            print response

        for block in response.iter_content(1024):
            if not block:
                break

            handle.write(block)

1. Remove the Python environment

There is no command to remove a virtualenv so you need to do that by hand, you will need to deactivate if you have it on and remove the folder:

deactivate
rm -rf <env name>

2. Create an env. with another Python version

When you create an environment the python uses the current version by default, so if you want another one you will need to specify at the moment you are creating it. To make and env. with Python 3.7 called MyEnv just type:

python3.7 -m venv MyEnv

Now to make with Python 2.X use virtualenv instead of venv:

python2.7 -m virtualenv MyEnv

3. List all Python versions on my machine

If any of the previous lines of code didn't worked you probably don't have the specific version installed. First list all your versions with:

ls -ls /usr/bin/python*

If you didn't find it, install Python 3.7 using apt-get:

sudo apt-get install python3.7

And with yum:

sudo yum install python3

4. Best practice: upgrade you pip (weekly)

pip install --upgrade pip

Yesterday, I got the same error: Failed building wheel for hddfancontrol when I ran pip3 install hddfancontrol. The result was Failed to build hddfancontrol. The cause was error: invalid command 'bdist_wheel' and Running setup.py bdist_wheel for hddfancontrol ... error. The error was fixed by running the following:

 pip3 install wheel

(From here.)

Alternatively, the "wheel" can be downloaded directly from here. When downloaded, it can be installed by running the following:

pip3 install "/the/file_path/to/wheel-0.32.3-py2.py3-none-any.whl"

IE11 no longer reports as MSIE, according to this list of changes it's intentional to avoid mis-detection.

What you can do if you really want to know it's IE is to detect the Trident/ string in the user agent if navigator.appName returns Netscape, something like (the untested);

function getInternetExplorerVersion()_x000D_
{_x000D_
  var rv = -1;_x000D_
  if (navigator.appName == 'Microsoft Internet Explorer')_x000D_
  {_x000D_
    var ua = navigator.userAgent;_x000D_
    var re = new RegExp("MSIE ([0-9]{1,}[\\.0-9]{0,})");_x000D_
    if (re.exec(ua) != null)_x000D_
      rv = parseFloat( RegExp.$1 );_x000D_
  }_x000D_
  else if (navigator.appName == 'Netscape')_x000D_
  {_x000D_
    var ua = navigator.userAgent;_x000D_
    var re  = new RegExp("Trident/.*rv:([0-9]{1,}[\\.0-9]{0,})");_x000D_
    if (re.exec(ua) != null)_x000D_
      rv = parseFloat( RegExp.$1 );_x000D_
  }_x000D_
  return rv;_x000D_
}_x000D_
_x000D_
console.log('IE version:', getInternetExplorerVersion());

Note that IE11 (afaik) still is in preview, and the user agent may change before release.

To represent the character you can use Universal Character Names (UCNs). The character '?' has the Unicode value U+0444 and so in C++ you could write it '\u0444' or '\U00000444'. Also if the source code encoding supports this character then you can just write it literally in your source code.

// both of these assume that the character can be represented with
// a single char in the execution encoding
char b = '\u0444';
char a = '?'; // this line additionally assumes that the source character encoding supports this character

Printing such characters out depends on what you're printing to. If you're printing to a Unix terminal emulator, the terminal emulator is using an encoding that supports this character, and that encoding matches the compiler's execution encoding, then you can do the following:

#include <iostream>

int main() {
    std::cout << "Hello, ? or \u0444!\n";
}

This program does not require that '?' can be represented in a single char. On OS X and most any modern Linux install this will work just fine, because the source, execution, and console encodings will all be UTF-8 (which supports all Unicode characters).

Things are harder with Windows and there are different possibilities with different tradeoffs.

Probably the best, if you don't need portable code (you'll be using wchar_t, which should really be avoided on every other platform), is to set the mode of the output file handle to take only UTF-16 data.

#include <iostream>
#include <io.h>
#include <fcntl.h>

int main() {
    _setmode(_fileno(stdout), _O_U16TEXT);
    std::wcout << L"Hello, \u0444!\n";
}

Portable code is more difficult.

Why don't you simply use the size() method on your Collection to get the number of elements?

Iterator is just meant to iterate,nothing else.

You can use:

1. size_t type, to remove warning messages
2. iterators + distance (like are first hint)
3. only iterators
4. function object

For example:

// simple class who output his value
class ConsoleOutput
{
public:
  ConsoleOutput(int value):m_value(value) { }
  int Value() const { return m_value; }
private:
  int m_value;
};

// functional object
class Predicat
{
public:
  void operator()(ConsoleOutput const& item)
  {
    std::cout << item.Value() << std::endl;
  }
};

void main()
{
  // fill list
  std::vector<ConsoleOutput> list;
  list.push_back(ConsoleOutput(1));
  list.push_back(ConsoleOutput(8));

  // 1) using size_t
  for (size_t i = 0; i < list.size(); ++i)
  {
    std::cout << list.at(i).Value() << std::endl;
  }

  // 2) iterators + distance, for std::distance only non const iterators
  std::vector<ConsoleOutput>::iterator itDistance = list.begin(), endDistance = list.end();
  for ( ; itDistance != endDistance; ++itDistance)
  {
    // int or size_t
    int const position = static_cast<int>(std::distance(list.begin(), itDistance));
    std::cout << list.at(position).Value() << std::endl;
  }

  // 3) iterators
  std::vector<ConsoleOutput>::const_iterator it = list.begin(), end = list.end();
  for ( ; it != end; ++it)
  {
    std::cout << (*it).Value() << std::endl;
  }
  // 4) functional objects
  std::for_each(list.begin(), list.end(), Predicat());
}

You can try this:

use database
go

declare @temp as int
select @temp = count(1) from sys.schemas where name = 'newSchema'

if @temp = 0 
begin
    exec ('create SCHEMA temporal')
    print 'The schema newSchema was created in database'
end 
else 
print 'The schema newSchema already exists in database'
go

An ES6 approach to clearing a group of radio buttons:

    Array.from( document.querySelectorAll('input[name="group-name"]:checked'), input => input.checked = false );

Question is a little vague.

list_of_lines = multiple_lines.split("\n")
for line in list_of_lines:
    list_of_items_in_line = line.split(",")
    first_int = int(list_of_items_in_line[0])

etc.

You'll need to also set the height of the element to 0 when it's hidden. I ran into this problem while using jQuery, my solution was to set the height and opacity to 0 when it's hidden, then change height to auto and opacity to 1 when it's un-hidden.

I'd recommend looking at jQuery. It's pretty easy to pick up and will allow you to do things like this a lot more easily.

$('#yesCheck').click(function() {
    $('#ifYes').slideDown();
});
$('#noCheck').click(function() {
    $('#ifYes').slideUp();
});

It's slightly better for performance to change the CSS with jQuery and use CSS3 animations to do the dropdown, but that's also more complex. The example above should work, but I haven't tested it.

Maybe I didn't understand the question correctly, but can you not use keyup if you want to capture both inputs?

$("input").bind("keyup",function(e){
    var value = this.value + String.fromCharCode(e.keyCode);
});

Since C++11, you can also use a lambda expression instead of defining a comparator struct:

auto comp = [](const string& a, const string& b) { return a.length() < b.length(); };
map<string, string, decltype(comp)> my_map(comp);

my_map["1"]      = "a";
my_map["three"]  = "b";
my_map["two"]    = "c";
my_map["fouuur"] = "d";

for(auto const &kv : my_map)
    cout << kv.first << endl;

Output:

1
two
three
fouuur

I'd like to repeat the final note of Georg's answer: When comparing by length you can only have one string of each length in the map as a key.

Code on Ideone

To diagnose better, you can capture the standard output and standard error streams of the external program, in order to see what output was generated and why it might not be running as expected.

Look up:

• ProcessStartInfo.RedirectStandardError and
• ProcessStartInfo.RedirectStandardOutput.

If you set each of those to true, then you can later call process.StandardOutput.ReadToEnd() and process.StandardError.ReadToEnd() to get the output into string variables, which you can easily inspect under the debugger, or output to trace or your log file.

Your code can be factored to this (in lieu of File.ReadAllBytes):

public byte[] ReadAllBytes(string fileName)
{
    byte[] buffer = null;
    using (FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read))
    {
        buffer = new byte[fs.Length];
        fs.Read(buffer, 0, (int)fs.Length);
    }
    return buffer;
} 

Note the Integer.MaxValue - file size limitation placed by the Read method. In other words you can only read a 2GB chunk at once.

Also note that the last argument to the FileStream is a buffer size.

I would also suggest reading about FileStream and BufferedStream.

As always a simple sample program to profile which is fastest will be most beneficial.

Also your underlying hardware will have a large effect on performance. Are you using server based hard disk drives with large caches and a RAID card with onboard memory cache? Or are you using a standard drive connected to the IDE port?

For CodeIgniter 4, use the following:

<?php    
    echo \CodeIgniter\CodeIgniter::CI_VERSION;
?>

if you don't have any content with 100% width, you can set the background color of the track to the same color of the body's background

If you're on Cygwin this command will show you the locations:

It says you don't have a local grunt so try:

npm install grunt

(without the -g it's a local grunt)

Though not directly related, make sure you have Gruntfile.js in your current folder.

At the risk of getting yelled at, i would get a javascript helper library like jquery or prototype they encapsulate the logic in nice methods - both have an .each method/iterator to do it - and they both strive to make it cross-browser compatible

EDIT: This answer was posted in 2008. Today much better constructs exist. This particular case could be solved with a .forEach.

button { 
  width:1000px; 
} 

or even

 button { 
    width:1000px !important
 } 

If thats what you mean

A token is a piece of data which only Server X could possibly have created, and which contains enough data to identify a particular user.

You might present your login information and ask Server X for a token; and then you might present your token and ask Server X to perform some user-specific action.

Tokens are created using various combinations of various techniques from the field of cryptography as well as with input from the wider field of security research. If you decide to go and create your own token system, you had best be really smart.

You could call during init or whatever Locale.setDefault() or -Duser.language=, -Duser.country=, and -Duser.variant= at the command line. Here's something on Sun's site.

Try this method

I was facing similar issue on Linux mint what I did was found out Debian version using,

$ cat /etc/debian_version buster/sid

then replaced Debian version in

From the Java tutorial, you need to create a new font and register it in the graphics environment:

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
ge.registerFont(Font.createFont(Font.TRUETYPE_FONT, new File("A.ttf")));

After this step is done, the font is available in calls to getAvailableFontFamilyNames() and can be used in font constructors.

This can be achieved using inline-block JS fiddle here

Note: if you have vs2010 and vs2008 and you want to reset the 2008, you will need to specify in command line the whole path. like this:

"C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe" /resetsettings

If you don't specify the path (like devenv.exe /resetsettings), it will reset the latest version of Visual studio installed on your computer.

I was able to solve this problem by removing node_modules then running npm install

My following JS solution is better than the other approaches here because it ensures that it will always say 'open' when the target is closed, and vice versa.

HTML:

<a href="#collapseExample" class="btn btn-primary" data-toggle="collapse" data-toggle-secondary="Close">
    Open
</a>
<div class="collapse" id="collapseExample">
  <div class="well">
    ...
  </div>
</div>

JS:

$('[data-toggle-secondary]').each(function() {
    var $toggle = $(this);
    var originalText = $toggle.text();
    var secondaryText = $toggle.data('toggle-secondary');
    var $target = $($toggle.attr('href'));

    $target.on('show.bs.collapse hide.bs.collapse', function() {
        if ($toggle.text() == originalText) {
            $toggle.text(secondaryText);
        } else {
            $toggle.text(originalText);
        }
    });
});

Examples:

$('[data-toggle-secondary]').each(function() {_x000D_
    var $toggle = $(this);_x000D_
    var originalText = $toggle.text();_x000D_
    var secondaryText = $toggle.data('toggle-secondary');_x000D_
    var $target = $($toggle.attr('href'));_x000D_
_x000D_
    $target.on('show.bs.collapse hide.bs.collapse', function() {_x000D_
        if ($toggle.text() == originalText) {_x000D_
            $toggle.text(secondaryText);_x000D_
        } else {_x000D_
            $toggle.text(originalText);_x000D_
        }_x000D_
    });_x000D_
});

Other benefits of this approach:

• the code is DRY and reusable
• each collapse button stays separate
• you only need to put one change into the HTML: adding the data-toggle-secondary attribute

In adition to the selected answer, if you're using .NET35 or .NET35 CE, you have to specify the index of the first byte to decode, and the number of bytes to decode:

string result = System.Text.Encoding.UTF8.GetString(byteArray,0,byteArray.Length);

I couldn't get the suggestion above at https://stackoverflow.com/a/20956456/1019307 to work. This worked for me though. For a file secondstring-20030401.jar that I stored in a libs/ directory in the root of the project:

repositories {
    mavenCentral()
    // Not everything is available in a Maven/Gradle repository.  Use a local 'libs/' directory for these.
    flatDir {
       dirs 'libs'
   }
}

...

compile name: 'secondstring-20030401'

SELECT ... INTO ... only works if the table specified in the INTO clause does not exist - otherwise, you have to use:

INSERT INTO dbo.TABLETWO
SELECT col1, col2
  FROM dbo.TABLEONE
 WHERE col3 LIKE @search_key

This assumes there's only two columns in dbo.TABLETWO - you need to specify the columns otherwise:

INSERT INTO dbo.TABLETWO
  (col1, col2)
SELECT col1, col2
  FROM dbo.TABLEONE
 WHERE col3 LIKE @search_key

I don't know about "standard way".

def remove_prefix(text, prefix):
    if text.startswith(prefix):
        return text[len(prefix):]
    return text  # or whatever

As noted by @Boris and @Stefan, on Python 3.9+ you can use

text.removeprefix(prefix)

with the same behavior.

There is an open source library called SVGInject that uses the onload attribute to trigger the injection. You can find the GitHub project at https://github.com/iconfu/svg-inject

Here is a minimal example using SVGInject:

<html>
  <head>
    <script src="svg-inject.min.js"></script>
  </head>
  <body>
    <img src="image.svg" onload="SVGInject(this)" />
  </body>
</html>

After the image is loaded the onload="SVGInject(this) will trigger the injection and the <img> element will be replaced by the contents of the SVG file provided in the src attribute.

It solves several issues with SVG injection:

1. SVGs can be hidden until injection has finished. This is important if a style is already applied during load time, which would otherwise cause a brief "unstyled content flash".

2. The <img> elements inject themselved automatically. If you add SVGs dynamically, you don't have to worry about calling the injection function again.

3. A random string is added to each ID in the SVG to avoid having the same ID multiple times in the document if an SVG is injected more than once.

SVGInject is plain Javascript and works with all browsers that support SVG.

Disclaimer: I am the co-author of SVGInject

I just wanted to add my opinion about this.

I think we can just use like this:

var haystack = 'hello world';
var needle = 'he';

if (haystack.indexOf(needle) == 0) {
  // Code if string starts with this substring
}

The only way to retrieve the correct value in your context is to run $.ajax() function synchronously (what actually contradicts to main AJAX idea). There is the special configuration attribute async you should set to false. In that case the main scope which actually contains $.ajax() function call is paused until the synchronous function is done, so, the return is called only after $.ajax().

function doSomething() {
    var status = 0;
    $.ajax({
        url: 'action.php',
        type: 'POST',
        data: dataString,
        async: false,
        success: function (txtBack) {
            if (txtBack == 1)
                status = 1;
        }
    });

    return status;
}

var response = doSomething();

You need to adjust three (or four) properties:

• Consumer side:fetch.message.max.bytes - this will determine the largest size of a message that can be fetched by the consumer.
• Broker side: replica.fetch.max.bytes - this will allow for the replicas in the brokers to send messages within the cluster and make sure the messages are replicated correctly. If this is too small, then the message will never be replicated, and therefore, the consumer will never see the message because the message will never be committed (fully replicated).
• Broker side: message.max.bytes - this is the largest size of the message that can be received by the broker from a producer.
• Broker side (per topic): max.message.bytes - this is the largest size of the message the broker will allow to be appended to the topic. This size is validated pre-compression. (Defaults to broker's message.max.bytes.)

I found out the hard way about number 2 - you don't get ANY exceptions, messages, or warnings from Kafka, so be sure to consider this when you are sending large messages.

Although all the approaches regarding the use of async: false are not good because of its deprecation and stuck the page untill the request comes back. Thus here are 2 ways to do it:

1st: Return whole ajax response in a function and then make use of done function to capture the response when the request is completed.(RECOMMENDED, THE BEST WAY)

function getAjax(url, data){
    return $.ajax({
        type: 'POST',
        url : url,              
        data: data,
        dataType: 'JSON',
        //async: true,  //NOT NEEDED
        success: function(response) {
            //Data = response;
        }
    });
 }

CALL THE ABOVE LIKE SO:

getAjax(youUrl, yourData).done(function(response){
    console.log(response);
});

FOR MULTIPLE AJAX CALLS MAKE USE OF $.when :

$.when( getAjax(youUrl, yourData), getAjax2(yourUrl2, yourData2) ).done(function(response){
    console.log(response);
});

2nd: Store the response in a cookie and then outside of the ajax call get that cookie value.(NOT RECOMMENDED)

        $.ajax({
            type: 'POST',
            url : url,              
            data: data,
            //async: false,    // No need to use this
            success: function(response) {
                Cookies.set(name, response);
            }
        });

        // Outside of the ajax call
        var response = Cookies.get(name);

NOTE: In the exmple above jquery cookies library is used.It is quite lightweight and works as snappy. Here is the link https://github.com/js-cookie/js-cookie

Timmy Franks had it right for me. We just had the issue today where the client had IE8 company-wide, and it was forcing the site we wrote for their intranet into compatibility mode. Setting "IE-Edge" seemed to fix it.

<httpProtocol>
  <customHeaders>
    <clear />
    <add name="X-UA-Compatible" value="IE=Edge" />
  </customHeaders>
</httpProtocol>

The fastest way is to modify your Manifest.xml. If for example you want to remove the logo of activity "Activity", and leave the logo in other activities, you can do the following:

<activity
      android:name=".home.XActivity"
      android:logo="@android:color/transparent"
      android:configChanges="orientation|keyboardHidden" />
 <activity
      android:name=".home.HomeActivity"
      android:configChanges="orientation|keyboardHidden" />

• return returns from the current function; it's a language keyword like for or break.
• exit() terminates the whole program, wherever you call it from. (After flushing stdio buffers and so on).

The only case when both do (nearly) the same thing is in the main() function, as a return from main performs an exit().

In most C implementations, main is a real function called by some startup code that does something like int ret = main(argc, argv); exit(ret);. The C standard guarantees that something equivalent to this happens if main returns, however the implementation handles it.

Example with return:

#include <stdio.h>

void f(){
    printf("Executing f\n");
    return;
}

int main(){
    f();
    printf("Back from f\n");
}

If you execute this program it prints:

Executing f
Back from f

Another example for exit():

#include <stdio.h>
#include <stdlib.h>

void f(){
    printf("Executing f\n");
    exit(0);
}

int main(){
    f();
    printf("Back from f\n");
}

If you execute this program it prints:

Executing f

You never get "Back from f". Also notice the #include <stdlib.h> necessary to call the library function exit().

Also notice that the parameter of exit() is an integer (it's the return status of the process that the launcher process can get; the conventional usage is 0 for success or any other value for an error).

The parameter of the return statement is whatever the return type of the function is. If the function returns void, you can omit the return at the end of the function.

Last point, exit() come in two flavors _exit() and exit(). The difference between the forms is that exit() (and return from main) calls functions registered using atexit() or on_exit() before really terminating the process while _exit() (from #include <unistd.h>, or its synonymous _Exit from #include <stdlib.h>) terminates the process immediately.

Now there are also issues that are specific to C++.

C++ performs much more work than C when it is exiting from functions (return-ing). Specifically it calls destructors of local objects going out of scope. In most cases programmers won't care much of the state of a program after the processus stopped, hence it wouldn't make much difference: allocated memory will be freed, file ressource closed and so on. But it may matter if your destructor performs IOs. For instance automatic C++ OStream locally created won't be flushed on a call to exit and you may lose some unflushed data (on the other hand static OStream will be flushed).

This won't happen if you are using the good old C FILE* streams. These will be flushed on exit(). Actually, the rule is the same that for registered exit functions, FILE* will be flushed on all normal terminations, which includes exit(), but not calls to _exit() or abort().

You should also keep in mind that C++ provide a third way to get out of a function: throwing an exception. This way of going out of a function will call destructor. If it is not catched anywhere in the chain of callers, the exception can go up to the main() function and terminate the process.

Destructors of static C++ objects (globals) will be called if you call either return from main() or exit() anywhere in your program. They wont be called if the program is terminated using _exit() or abort(). abort() is mostly useful in debug mode with the purpose to immediately stop the program and get a stack trace (for post mortem analysis). It is usually hidden behind the assert() macro only active in debug mode.

When is exit() useful ?

exit() means you want to immediately stops the current process. It can be of some use for error management when we encounter some kind of irrecoverable issue that won't allow for your code to do anything useful anymore. It is often handy when the control flow is complicated and error codes has to be propagated all way up. But be aware that this is bad coding practice. Silently ending the process is in most case the worse behavior and actual error management should be preferred (or in C++ using exceptions).

Direct calls to exit() are especially bad if done in libraries as it will doom the library user and it should be a library user's choice to implement some kind of error recovery or not. If you want an example of why calling exit() from a library is bad, it leads for instance people to ask this question.

There is an undisputed legitimate use of exit() as the way to end a child process started by fork() on Operating Systems supporting it. Going back to the code before fork() is usually a bad idea. This is the rationale explaining why functions of the exec() family will never return to the caller.

To elaborate on everyone's great answers, here is the implementation that was used in the Mozilla Fathom project:

/**
 * Yield an element and each of its ancestors.
 */
export function *ancestors(element) {
    yield element;
    let parent;
    while ((parent = element.parentNode) !== null && parent.nodeType === parent.ELEMENT_NODE) {
        yield parent;
        element = parent;
    }
}

/**
 * Return whether an element is practically visible, considering things like 0
 * size or opacity, ``visibility: hidden`` and ``overflow: hidden``.
 *
 * Merely being scrolled off the page in either horizontally or vertically
 * doesn't count as invisible; the result of this function is meant to be
 * independent of viewport size.
 *
 * @throws {Error} The element (or perhaps one of its ancestors) is not in a
 *     window, so we can't find the `getComputedStyle()` routine to call. That
 *     routine is the source of most of the information we use, so you should
 *     pick a different strategy for non-window contexts.
 */
export function isVisible(fnodeOrElement) {
    // This could be 5x more efficient if https://github.com/w3c/csswg-drafts/issues/4122 happens.
    const element = toDomElement(fnodeOrElement);
    const elementWindow = windowForElement(element);
    const elementRect = element.getBoundingClientRect();
    const elementStyle = elementWindow.getComputedStyle(element);
    // Alternative to reading ``display: none`` due to Bug 1381071.
    if (elementRect.width === 0 && elementRect.height === 0 && elementStyle.overflow !== 'hidden') {
        return false;
    }
    if (elementStyle.visibility === 'hidden') {
        return false;
    }
    // Check if the element is irrevocably off-screen:
    if (elementRect.x + elementRect.width < 0 ||
        elementRect.y + elementRect.height < 0
    ) {
        return false;
    }
    for (const ancestor of ancestors(element)) {
        const isElement = ancestor === element;
        const style = isElement ? elementStyle : elementWindow.getComputedStyle(ancestor);
        if (style.opacity === '0') {
            return false;
        }
        if (style.display === 'contents') {
            // ``display: contents`` elements have no box themselves, but children are
            // still rendered.
            continue;
        }
        const rect = isElement ? elementRect : ancestor.getBoundingClientRect();
        if ((rect.width === 0 || rect.height === 0) && elementStyle.overflow === 'hidden') {
            // Zero-sized ancestors don’t make descendants hidden unless the descendant
            // has ``overflow: hidden``.
            return false;
        }
    }
    return true;
}

It checks on every parent's opacity, display, and rectangle.

jQuery < 1.8

May I suggest that you use $.ajax() instead of $.post() as it's much more customizable.

If you are calling $.post(), e.g., like this:

$.post( url, data, success, dataType );

You could turn it into its $.ajax() equivalent:

$.ajax({
  type: 'POST',
  url: url,
  data: data,
  success: success,
  dataType: dataType,
  async:false
});

Please note the async:false at the end of the $.ajax() parameter object.

Here you have a full detail of the $.ajax() parameters: jQuery.ajax() – jQuery API Documentation.

jQuery >=1.8 "async:false" deprecation notice

jQuery >=1.8 won't block the UI during the http request, so we have to use a workaround to stop user interaction as long as the request is processed. For example:

• use a plugin e.g. BlockUI;
• manually add an overlay before calling $.ajax(), and then remove it when the AJAX .done() callback is called.

Please have a look at this answer for an example.

Just call moment as a function without any arguments:

moment()

For timezone information with moment, look at the moment-timezone package: http://momentjs.com/timezone/

I've been interested in the original question here and related ones.

For an answer, this week I did some experiments with XCOPY.

To help answer the original question, here I post the results of my experiments.

I did the experiments on Windows 7 64 bit Professional SP1 with the copy of XCOPY that came with the operating system.

For the experiments, I wrote some code in the scripting language Open Object Rexx and the editor macro language Kexx with the text editor KEdit.

XCOPY was called from the Rexx code. The Kexx code edited the screen output of XCOPY to focus on the crucial results.

The experiments all had to do with using XCOPY to copy one directory with several files and subdirectories.

The experiments consisted of 10 cases. Each case adjusted the arguments to XCOPY and called XCOPY once. All 10 cases were attempting to do the same copying operation.

Here are the main results:

(1) Of the 10 cases, only three did copying. The other 7 cases right away, just from processing the arguments to XCOPY, gave error messages, e.g.,

Invalid path

Access denied

with no files copied.

Of the three cases that did copying, they all did the same copying, that is, gave the same results.

(2) If want to copy a directory X and all the files and directories in directory X, in the hierarchical file system tree rooted at directory X, then apparently XCOPY -- and this appears to be much of the original question -- just will NOT do that.

One consequence is that if using XCOPY to copy directory X and its contents, then CAN copy the contents but CANNOT copy the directory X itself; thus, lose the time-date stamp on directory X, its archive bit, data on ownership, attributes, etc.

Of course if directory X is a subdirectory of directory Y, an XCOPY of Y will copy all of the contents of directory Y WITH directory X. So in this way can get a copy of directory X. However, the copy of directory X will have its time-date stamp of the time of the run of XCOPY and NOT the time-date stamp of the original directory X.

This change in time-date stamps can be awkward for a copy of a directory with a lot of downloaded Web pages: The HTML file of the Web page will have its original time-date stamp, but the corresponding subdirectory for files used by the HTML file will have the time-date stamp of the run of XCOPY. So, when sorting the copy on time date stamps, all the subdirectories, the HTML files and the corresponding subdirectories, e.g.,

x.htm

x_files

can appear far apart in the sort on time-date.

Hierarchical file systems go way back, IIRC to Multics at MIT in 1969, and since then lots of people have recognized the two cases, given a directory X, (i) copy directory X and all its contents and (ii) copy all the contents of X but not directory X itself. Well, if only from the experiments, XCOPY does only (ii).

So, the results of the 10 cases are below. For each case, in the results the first three lines have the first three arguments to XCOPY. So, the first line has the tree name of the directory to be copied, the 'source'; the second line has the tree name of the directory to get the copies, the 'destination', and the third line has the options for XCOPY. The remaining 1-2 lines have the results of the run of XCOPY.

One big point about the options is that options /X and /O result in result

Access denied

To see this, compare case 8 with the other cases that were the same, did not have /X and /O, but did copy.

These experiments have me better understand XCOPY and contribute an answer to the original question.

DML have to be committed or rollbacked. DDL cannot.

http://www.orafaq.com/faq/what_are_the_difference_between_ddl_dml_and_dcl_commands

You can switch auto-commit on and that's again only for DML. DDL are never part of transactions and therefore there is nothing like an explicit commit/rollback.

truncate is DDL and therefore commited implicitly.

Edit
I've to say sorry. Like @DCookie and @APC stated in the comments there exist sth like implicit commits for DDL. See here for a question about that on Ask Tom. This is in contrast to what I've learned and I am still a bit curious about.

This page helped me a lot. The code I got from here was meant to remove a click event from a button. I need to remove double click events from some panels and click events from some buttons. So I made a control extension, which will remove all event handlers for a certain event.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Windows.Forms;
using System.Reflection;
public static class EventExtension
{
    public static void RemoveEvents<T>(this T target, string eventName) where T:Control
    {
        if (ReferenceEquals(target, null)) throw new NullReferenceException("Argument \"target\" may not be null.");
        FieldInfo fieldInfo = typeof(Control).GetField(eventName, BindingFlags.Static | BindingFlags.NonPublic);
        if (ReferenceEquals(fieldInfo, null)) throw new ArgumentException(
            string.Concat("The control ", typeof(T).Name, " does not have a property with the name \"", eventName, "\""), nameof(eventName));
        object eventInstance = fieldInfo.GetValue(target);
        PropertyInfo propInfo = typeof(T).GetProperty("Events", BindingFlags.NonPublic | BindingFlags.Instance);
        EventHandlerList list = (EventHandlerList)propInfo.GetValue(target, null);
        list.RemoveHandler(eventInstance, list[eventInstance]);
    }
}

Now, the usage of this extenstion. If you need to remove click events from a button,

Button button = new Button();
button.RemoveEvents(nameof(button.EventClick));

If you need to remove doubleclick events from a panel,

Panel panel = new Panel();
panel.RemoveEvents(nameof(panel.EventDoubleClick));

I am not an expert in C#, so if there are any bugs please forgive me and kindly let me know about it.

For future friendliness, I second the recommendation for classList with polyfill/shim: https://developer.mozilla.org/en-US/docs/Web/API/Element/classList#wrapper

var elem = document.getElementById( 'some-id' );
elem.classList.add('some-class'); // Add class
elem.classList.remove('some-other-class'); // Remove class
elem.classList.toggle('some-other-class'); // Add or remove class
if ( elem.classList.contains('some-third-class') ) { // Check for class
    console.log('yep!');
}

Since phone numbers must conform to a pattern, you can use regular expressions to match the entered phone number against the pattern you define in regexp.

php has both ereg and preg_match() functions. I'd suggest using preg_match() as there's more documentation for this style of regex.

An example

$phone = '000-0000-0000';

if(preg_match("/^[0-9]{3}-[0-9]{4}-[0-9]{4}$/", $phone)) {
  // $phone is valid
}

The object exists in some scope, so you can almost always access the variable via this syntax:

var objname = "myobject";
containing_scope_reference[objname].some_property = 'some value';

The only place where this gets tricky is when you are in a closed scope and you want access to a top-level local variable. When you have something like this:

(function(){
    var some_variable = {value: 25};
    var x = "some_variable";
    console.log(this[x], window[x]); // Doesn't work
})();

You can get around that by using eval instead to access the current scope chain ... but I don't recommend it unless you've done a lot of testing and you know that that's the best way to go about things.

(function(){
    var some_variable = {value: 25};
    var x = "some_variable";
    eval(x).value = 42;
    console.log(some_variable); // Works
})();

Your best bet is to have a reference to a name in an always-going-to-be-there object (like this in the global scope or a private top-level variable in a local scope) and put everything else in there.

Thus:

var my_outer_variable = {};
var outer_pointer = 'my_outer_variable';
// Reach my_outer_variable with this[outer_pointer]
// or window[outer_pointer]

(function(){
    var my_inner_scope = {'my_inner_variable': {} };
    var inner_pointer = 'my_inner_variable';
    // Reach my_inner_variable by using
    // my_inner_scope[inner_pointer]
})();

Open up your device’s “Settings”. This can be done by pressing the Menu button while on your home screen and tapping settings icon then scroll down to developer options and tap it then you will see on the top right a on off switch select on and then tap ok, thats it you all done.

From the MySQL manual

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas. Example:

INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);

setTimeout is a kind of Thread, it holds a operation for a given time and execute.

setTimeout(function,time_in_mills);

in here the first argument should be a function type; as an example if you want to print your name after 3 seconds, your code should be something like below.

setTimeout(function(){console.log('your name')},3000);

Key point to remember is, what ever you want to do by using the setTimeout method, do it inside a function. If you want to call some other method by parsing some parameters, your code should look like below:

setTimeout(function(){yourOtherMethod(parameter);},3000);

I have encountered the same problem today and found that beyond that 4000 character limit, I had to split the dynamic query into two strings and concatenate them when executing the query.

DECLARE @Query NVARCHAR(max);
DECLARE @Query2 NVARCHAR(max);
SET @Query = 'SELECT...' -- some of the query gets set here
SET @Query2 = '...' -- more query gets added on, etc.

EXEC (@Query + @Query2)

var s = '/Controller/Action?id=11112&value=4444';
s = s.substring(0, s.indexOf('?'));
document.write(s);

Sample here

I should also mention that native string functions are much faster than regular expressions, which should only really be used when necessary (this isn't one of those cases).

Updated code to account for no '?':

var s = '/Controller/Action';
var n = s.indexOf('?');
s = s.substring(0, n != -1 ? n : s.length);
document.write(s);

Sample here

There are a lot of good options for your case here. Still you should considering using the POST body.

The query string is perfect for your example, but if you have something more complicated, e.g. an arbitrary long list of items or boolean conditionals, you might want to define the post as a document, that the client sends over POST.

This allows a more flexible description of the search, as well as avoids the Server URL length limit.

I encountered a similar problem when I was using the below to obtain connection factory ConnectionFactory factory = new
ActiveMQConnectionFactory("admin","admin","tcp://:61616");

Its resolved when I changed it to the below

ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://:61616");

The below then showed that my Q size was increasing.. http://:8161/admin/queues.jsp

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
}

Update on 11 December 2015

Username + password is no longer a recommended solution. This is due to

I tried this and Gmail sent the email used as username in this code an email saying that We recently blocked a sign-in attempt to your Google Account, and directed me to this support page: support.google.com/accounts/answer/6010255 so it looks for it to work, the email account being used to send needs to reduce their own security

Google had released Gmail API - https://developers.google.com/gmail/api/?hl=en. We should use oAuth2 method, instead of username + password.

Here's the code snippet to work with Gmail API.

GoogleMail.java

        Properties props = new Properties();
        Session session = Session.getDefaultInstance(props, null);

        MimeMessage email = new MimeMessage(session);
        InternetAddress tAddress = new InternetAddress(to);
        InternetAddress cAddress = cc.isEmpty() ? null : new InternetAddress(cc);
        InternetAddress fAddress = new InternetAddress(from);

        email.setFrom(fAddress);
        if (cAddress != null) {
            email.addRecipient(javax.mail.Message.RecipientType.CC, cAddress);
        }
        email.addRecipient(javax.mail.Message.RecipientType.TO, tAddress);
        email.setSubject(subject);
        email.setText(bodyText);
        return email;
    }

    private static Message createMessageWithEmail(MimeMessage email) throws MessagingException, IOException {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        email.writeTo(baos);
        String encodedEmail = Base64.encodeBase64URLSafeString(baos.toByteArray());
        Message message = new Message();

    }

    public static void Send(Gmail service, String recipientEmail, String ccEmail, String fromEmail, String title, String message) throws IOException, MessagingException {
        Message m = createMessageWithEmail(createEmail(recipientEmail, ccEmail, fromEmail, title, message));
        service.users().messages().send("me", m).execute();
    }
}

To provide a user friendly way of oAuth2 authentication, I made use of JavaFX, to display the following input dialog

Let me explain clearly.. If you are familiar With rdbms.. Index is database.. And index type is table.. It mean index is collection of index types., like collection of tables as database (DB).

in NOSQL.. Index is database and index type is collections. Group of collection as database..

To execute those queries... U need to install CURL for Windows.

Curl is nothing but a command line rest tool.. If you want a graphical tool.. Try

Sense plugin for chrome...

Hope it helps..

As the error clearly states, OffenceBox.Text() is not a function and therefore doesn't make sense.

Check for nil and unwrap using "!":

let color = colorChoiceSegmentedControl.titleForSegmentAtIndex(colorChoiceSegmentedControl.selectedSegmentIndex)

println(color) // Optional("Red")

if color != nil {
    println(color!) // "Red"
    let imageURLString = "http://hahaha.com/ha.php?color=\(color!)"
    println(imageURLString)
    //"http://hahaha.com/ha.php?color=Red"
}

Sometimes you may need to plot color precisely based on the x-value case. For example, you may have a dataframe with 3 types of variables and some data points. And you want to do following,

• Plot points corresponding to Physical variable 'A' in RED.
• Plot points corresponding to Physical variable 'B' in BLUE.
• Plot points corresponding to Physical variable 'C' in GREEN.

In this case, you may have to write to short function to map the x-values to corresponding color names as a list and then pass on that list to the plt.scatter command.

x=['A','B','B','C','A','B']
y=[15,30,25,18,22,13]

# Function to map the colors as a list from the input list of x variables
def pltcolor(lst):
    cols=[]
    for l in lst:
        if l=='A':
            cols.append('red')
        elif l=='B':
            cols.append('blue')
        else:
            cols.append('green')
    return cols
# Create the colors list using the function above
cols=pltcolor(x)

plt.scatter(x=x,y=y,s=500,c=cols) #Pass on the list created by the function here
plt.grid(True)
plt.show()

class Student(object):
    name = ""
    age = 0
    major = ""

    # The class "constructor" - It's actually an initializer 
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

def make_student(name, age, major):
    student = Student(name, age, major)
    return student

Note that even though one of the principles in Python's philosophy is "there should be one—and preferably only one—obvious way to do it", there are still multiple ways to do this. You can also use the two following snippets of code to take advantage of Python's dynamic capabilities:

class Student(object):
    name = ""
    age = 0
    major = ""

def make_student(name, age, major):
    student = Student()
    student.name = name
    student.age = age
    student.major = major
    # Note: I didn't need to create a variable in the class definition before doing this.
    student.gpa = float(4.0)
    return student

I prefer the former, but there are instances where the latter can be useful – one being when working with document databases like MongoDB.

Use Reflection:

Type type = obj.GetType();
PropertyInfo[] properties = type.GetProperties();

foreach (PropertyInfo property in properties)
{
    Console.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(obj, null));
}

for Excel - what tools/reference item must be added to gain access to BindingFlags, as there is no "System.Reflection" entry in the list

Edit: You can also specify a BindingFlags value to type.GetProperties():

BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;
PropertyInfo[] properties = type.GetProperties(flags);

That will restrict the returned properties to public instance properties (excluding static properties, protected properties, etc).

You don't need to specify BindingFlags.GetProperty, you use that when calling type.InvokeMember() to get the value of a property.

It seems that you are looking to parse commandline arguments into your bash script. I have searched for this recently myself. I came across the following which I think will assist you in parsing the arguments:

http://rsalveti.wordpress.com/2007/04/03/bash-parsing-arguments-with-getopts/

I added the snippet below as a tl;dr

#using : after a switch variable means it requires some input (ie, t: requires something after t to validate while h requires nothing.
while getopts “ht:r:p:v” OPTION
do
     case $OPTION in
         h)
             usage
             exit 1
             ;;
         t)
             TEST=$OPTARG
             ;;
         r)
             SERVER=$OPTARG
             ;;
         p)
             PASSWD=$OPTARG
             ;;
         v)
             VERBOSE=1
             ;;
         ?)
             usage
             exit
             ;;
     esac
done

if [[ -z $TEST ]] || [[ -z $SERVER ]] || [[ -z $PASSWD ]]
then
     usage
     exit 1

Updated Answer

Here I am giving 3 approaches for the same.

[1] Math Solution using Math.Truncate

 var float_number = 12.345;
 var result = float_number - Math.Truncate(float_number);

// input : 1.05
// output : "0.050000000000000044"

// input : 10.2
// output : 0.19999999999999929

If this is not the result what you are expecting, then you have to change the result to the form which you want (but you might do some string manipulations again.)

[2] using multiplier [which is 10 to the power of N (e.g. 10² or 10³) where N is the number of decimal places]

       // multiplier is " 10 to the power of 'N'" where 'N' is the number 
       // of decimal places
       int multiplier = 1000;  
       double double_value = 12.345;
       int double_result = (int)((double_value - (int)double_value) * multiplier);

// output 345

If the number of decimal places is not fixed, then this approach may create problems.

[3] using "Regular Expressions (REGEX)"

we should be very careful while writing solutions with string. This would not be preferable except some cases.

If you are going to do some string operations with decimal places, then this would be preferable

    string input_decimal_number = "1.50";
    var regex = new System.Text.RegularExpressions.Regex("(?<=[\\.])[0-9]+");
    if (regex.IsMatch(input_decimal_number))
    {
        string decimal_places = regex.Match(input_decimal_number).Value;
    }

// input : "1.05"
// output : "05"

// input : "2.50"
// output : "50"

// input : "0.0550"
// output : "0550"

you can find more about Regex on http://www.regexr.com/

I am using this and got I worked

"query": {
        "query_string" : {
            "query" : "*test*",
            "fields" : ["field1","field2"],
            "analyze_wildcard" : true,
            "allow_leading_wildcard": true
        }
    }

Summary

With either string concatenation or string interpolation (via template literals).

Here with JavaScript template literal:

function geoPreview() {
    var lat = document.getElementById("lat").value;
    var long = document.getElementById("long").value;

    window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${lat}&lon=${long}&setLatLon=Set`;
}

Both parameters are unused and can be removed.

Remarks

String Concatenation

Join strings with the + operator:

window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=" + elemA + "&lon=" + elemB + "&setLatLon=Set";

String Interpolation

For more concise code, use JavaScript template literals to replace expressions with their string representations. Template literals are enclosed by `` and placeholders surrounded with ${}:

window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${elemA}&lon=${elemB}&setLatLon=Set`;

Template literals are available since ECMAScript 2015 (ES6).

tuple = 1 record; n-tuple = ordered list of 'n' records; Elmasri Navathe book (page 198 3rd edition).

record = either ordered or unordered.

Let's not forget good old parameters. When starting your *.bat or *.cmd file you can add up to nine parameters after the command file name:

call myscript.bat \\path\to\my\file.ext type
call myscript.bat \\path\to\my\file.ext "Del /F"

Example script

The myscript.bat could be something like this:

@Echo Off
Echo The path of this scriptfile %~0
Echo The name of this scriptfile %~n0
Echo The extension of this scriptfile %~x0
Echo.
If "%~2"=="" (
   Echo Parameter missing, quitting.
   GoTo :EOF
)
If Not Exist "%~1" (
   Echo File does not exist, quitting.
   GoTo :EOF
)
Echo Going to %~2 this file: %~1
%~2 "%~1"
If %errorlevel%  NEQ 0 (
   Echo Failed to %~2 the %~1.
)
@Echo On

Example output

c:\>c:\bats\myscript.bat \\server\path\x.txt type
The path of this scriptfile c:\bats\myscript.bat
The name of this scriptfile myscript
The extension of this scriptfile .bat

Going to type this file: \\server\path\x.txt
This is the content of the file:
Some alphabets: ABCDEFG abcdefg
Some numbers: 1234567890

c:\>c:\bats\myscript.bat \\server\path\x.txt "del /f "
The path of this scriptfile c:\bats\myscript.bat
The name of this scriptfile myscript
The extension of this scriptfile .bat

Going to del /f  this file: \\server\path\x.txt

c:\>

This is the only solution that would work for me, when I required a space in between the columns being merged.

select concat(concat(column1,' '), column2)

patrick dw's answer is right on.

For kicks and giggles I thought I would post a simple way to return an array of all the IDs.

var arrayOfIds = $.map($(".myClassName"), function(n, i){
  return n.id;
});
alert(arrayOfIds);

We don't need to bother entering the current line number.

If you would like to change each foo to bar for current line (.) and the two next lines (+2), simply do:

:.,+2s/foo/bar/g

If you want to confirm before changes are made, replace g with gc:

:.,+2s/foo/bar/gc

You can convert type of plaintext to string:

f.write(str(plaintext) + '\n')

Going to answer this myself (correct me if I'm wrong):

It is not possible to iterate over a group of rows (like an array) in Excel without VBA installed / macros enabled.

The compiler may well optimize the second form into the first form, but it doesn't have to.

#include <iostream>

    public:
        A() { std::cerr << "Empty constructor" << std::endl; }
        A(const A&) { std::cerr << "Copy constructor" << std::endl; }
        A(const char* str) { std::cerr << "char constructor: " << str << std::endl; }
        ~A() { std::cerr << "destructor" << std::endl; }
};

void direct()
{
    std::cerr << std::endl << "TEST: " << __FUNCTION__ << std::endl;
    A a(__FUNCTION__);
    static_cast<void>(a); // avoid warnings about unused variables
}

void assignment()
{
    std::cerr << std::endl << "TEST: " << __FUNCTION__ << std::endl;
    A a = A(__FUNCTION__);
    static_cast<void>(a); // avoid warnings about unused variables
}

void prove_copy_constructor_is_called()
{
    std::cerr << std::endl << "TEST: " << __FUNCTION__ << std::endl;
    A a(__FUNCTION__);
    A b = a;
    static_cast<void>(b); // avoid warnings about unused variables
}

int main()
{
    direct();
    assignment();
    prove_copy_constructor_is_called();
    return 0;
}

Output from gcc 4.4:

You can use lapply to pass each column to str_length, then cbind it to your original data.frame...

library(stringr)

out <- lapply( df , str_length )    
df <- cbind( df , out )

#     col1     col2 col1 col2
#1     abc adf qqwe    3    8
#2    abcd        d    4    1
#3       a        e    1    1
#4 abcdefg        f    7    1

In vb.net or C# I would expect that the fastest general approach to compare a variable against any reasonable number of separately-named objects (as opposed to e.g. all the things in a collection) will be to simply compare each object against the comparand much as you have done. It is certainly possible to create an instance of a collection and see if it contains the object, and doing so may be more expressive than comparing the object against all items individually, but unless one uses a construct which the compiler can explicitly recognize, such code will almost certainly be much slower than simply doing the individual comparisons. I wouldn't worry about speed if the code will by its nature run at most a few hundred times per second, but I'd be wary of the code being repurposed to something that's run much more often than originally intended.

An alternative approach, if a variable is something like an enumeration type, is to choose power-of-two enumeration values to permit the use of bitmasks. If the enumeration type has 32 or fewer valid values (e.g. starting Harry=1, Ron=2, Hermione=4, Ginny=8, Neville=16) one could store them in an integer and check for multiple bits at once in a single operation ((if ((thisOne & (Harry | Ron | Neville | Beatrix)) != 0) /* Do something */. This will allow for fast code, but is limited to enumerations with a small number of values.

A somewhat more powerful approach, but one which must be used with care, is to use some bits of the value to indicate attributes of something, while other bits identify the item. For example, bit 30 could indicate that a character is male, bit 29 could indicate friend-of-Harry, etc. while the lower bits distinguish between characters. This approach would allow for adding characters who may or may not be friend-of-Harry, without requiring the code that checks for friend-of-Harry to change. One caveat with doing this is that one must distinguish between enumeration constants that are used to SET an enumeration value, and those used to TEST it. For example, to set a variable to indicate Harry, one might want to set it to 0x60000001, but to see if a variable IS Harry, one should bit-test it with 0x00000001.

One more approach, which may be useful if the total number of possible values is moderate (e.g. 16-16,000 or so) is to have an array of flags associated with each value. One could then code something like "if (((characterAttributes[theCharacter] & chracterAttribute.Male) != 0)". This approach will work best when the number of characters is fairly small. If array is too large, cache misses may slow down the code to the point that testing against a small number of characters individually would be faster.

From find manual:

NON-BUGS         

   Operator precedence surprises
   The command find . -name afile -o -name bfile -print will never print
   afile because this is actually equivalent to find . -name afile -o \(
   -name bfile -a -print \).  Remember that the precedence of -a is
   higher than that of -o and when there is no operator specified
   between tests, -a is assumed.

   “paths must precede expression” error message
   $ find . -name *.c -print
   find: paths must precede expression
   Usage: find [-H] [-L] [-P] [-Olevel] [-D ... [path...] [expression]

   This happens because *.c has been expanded by the shell resulting in
   find actually receiving a command line like this:
   find . -name frcode.c locate.c word_io.c -print
   That command is of course not going to work.  Instead of doing things
   this way, you should enclose the pattern in quotes or escape the
   wildcard:
   $ find . -name '*.c' -print
   $ find . -name \*.c -print

I did some speed test. Lets say that if the string is likely to be a number the try/except strategy is the fastest possible.If the string is not likely to be a number and you are interested in Integer check, it worths to do some test (isdigit plus heading '-'). If you are interested to check float number, you have to use the try/except code whitout escape.

if you are using windows, in WinDef.h you have:

typedef unsigned char BYTE;

Few months ago I was working with jax-ws web service in j2ee application, There we were using CXF wsdl2java to generate WS client stub from the WSDL file and with those client stubs we consumed the web services. Few weeks ago, when I was trying to consume the web service in the same way in android platform I couldn't, because the android jar has not all the "jax-ws" supporting classes in it. That time I didn't find any such tool ( if I wasn't failed to google efficiently) to meet my requirement --

• Get the client stub from the WSDL.
• And call the Service with some argument (java business request object).
• Get the Response Business Object.

So, I developed my own Android SOAP Client Generation Tool. Where you have to follow these steps :

• From WSDL Get WS Client Stub, Put it in your project.
• Say for Some Service "ComplexOperationService", Instantiate the Service, Get the Endpoint port and call the service method, and get the response from the Web service :

eg:

ComplexOperationService service = new ComplexOperationService( );
ComplexOperation port= service.getComplexOperationPort();    
SomeComplexRequest request = --Get some complex request----;    
SomeComplexResp resp = port.operate( request  );

• You don't need to care about the service class/req/response classes or any other classes and the method as well, as you know its all are generated from WSDL.
• And of course you needn't be aware of the soap action/envelop/namespace etc. Just call the method as we, developers do all the time.

True you can't have different sized slides. NOT true the size of you slide doesn't matter. It will size it to your resolution, but you can click on the magnifying icon(at least on PP 2013) and you can then scroll in all directions of your slide in original resolution.

try

console.log($("#"+d));

your solution is passing the double quotes as part of the string.

JavaScript is a dynamically typed language. This means that you never need to declare the type of a function argument (or any other variable). So, your code will work as long as arrayP is an array and contains elements with a value property.
