The document and window are different objects and they have some different events. Using addEventListener() on them listens to events destined for a different object. You should use the one that actually has the event you are interested in.

For example, there is a "resize" event on the window object that is not on the document object.

For example, the "DOMContentLoaded" event is only on the document object.

So basically, you need to know which object receives the event you are interested in and use .addEventListener() on that particular object.

Here's an interesting chart that shows which types of objects create which types of events: https://developer.mozilla.org/en-US/docs/DOM/DOM_event_reference

If you are listening to a propagated event (such as the click event), then you can listen for that event on either the document object or the window object. The only main difference for propagated events is in timing. The event will hit the document object before the window object since it occurs first in the hierarchy, but that difference is usually immaterial so you can pick either. I find it generally better to pick the closest object to the source of the event that meets your needs when handling propagated events. That would suggest that you pick document over window when either will work. But, I'd often move even closer to the source and use document.body or even some closer common parent in the document (if possible).

• compile: used when we need to modify directive template, like add new expression, append another directive inside this directive
• controller: used when we need to share/reuse $scope data
• link: it is a function which used when we need to attach event handler or to manipulate DOM.

All this talk about collation seem a bit over-complicated. Why not just use something like:

IF UPPER(@@VERSION) NOT LIKE '%AZURE%'

Then your check is case insensitive whatever the collation

step 1: use the command : npm install jquery --save

step 2: you can simply import angular as :

import $ from 'jquery';

that's all .

An example would be :

import { Component } from '@angular/core';
import  $ from 'jquery';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

export class AppComponent {
  title = 'app';
  constructor(){
    console.log($('body'));
  }


}

By passing keyword args.

def add_bullet(**kwargs):
    #check for the arguments listed above and do the proper things

another shortcut i personally prefer more than .is() or .length:

if($('.myclass:visible')[0]){
   // is visible
}else {
   // is hidden
}

You can do checks using lookarounds:

^(?=.*\bjack\b)(?=.*\bjames\b).*$

Test it.

This approach has the advantage that you can easily specify multiple conditions.

^(?=.*\bjack\b)(?=.*\bjames\b)(?=.*\bjason\b)(?=.*\bjules\b).*$

Even if it is really discouraged to use merge cells in Excel (use Center Across Selection for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).

Hence, you can get the value of merged cells in range B4:B11 in several ways:

• Range("B4").Value
• Range("B4:B11").Cells(1).Value
• Range("B4:B11").Cells(1,1).Value

You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty.

Also note that Range("B4:B11").Value won't work (raises an execution error number 13 if you try to Debug.Print it) because it returns an array.

Try this:

$zip = new ZipArchive;
$zip->open('myzip.zip', ZipArchive::CREATE);
foreach (glob("target_folder/*") as $file) {
    $zip->addFile($file);
    if ($file != 'target_folder/important.txt') unlink($file);
}
$zip->close();

This will not zip recursively though.

I'm coming from a SQL Server background also and spent the past 2 weeks figuring out how to run scripts like this in IBM Data Studio. Hope it helps.

CREATE VARIABLE v_lookupid INTEGER DEFAULT (4815162342); --where 4815162342 is your variable data 
  SELECT * FROM DB1.PERSON WHERE PERSON_ID = v_lookupid;
  SELECT * FROM DB1.PERSON_DATA WHERE PERSON_ID = v_lookupid;
  SELECT * FROM DB1.PERSON_HIST WHERE PERSON_ID = v_lookupid;
DROP VARIABLE v_lookupid; 

I think this comes closest to what you wish:

(From IntelliJ IDEA Q&A for Eclipse Users):

The above can be combined with a recently introduced option in Compiler settings to get a view very similar to that of Eclipse.

Things to do:

1. Switch to 'Problems' view in the Project pane:
   
   

2. Enable the setting to compile the project automatically :
   
   

3. Finally, look at the Problems view:
   
   

Here is a comparison of what the same project (with a compilation error) looks like in Intellij IDEA 13.xx and Eclipse Kepler:

I've never had a problem with doing it like this:

<form>
  <div>
    <input type="checkbox" id="cb" /> <label for="cb">Label text</label>
  </div>
</form>

Here is a solution which blocks all non numeric input from being entered into the text-field.

html

<input type="text" id="numbersOnly" />

javascript

var input = document.getElementById('numbersOnly');
input.onkeydown = function(e) {
    var k = e.which;
    /* numeric inputs can come from the keypad or the numeric row at the top */
    if ( (k < 48 || k > 57) && (k < 96 || k > 105)) {
        e.preventDefault();
        return false;
    }
};?

If it's a percentage width, then yes, it is respected. As Martin pointed out, things break down when you get to fractional pixels, but if your percentage values yield integer pixel value (e.g. 50.5% of 200px in the example) you'll get sensible, expected behaviour.

Edit: I've updated the example to show what happens to fractional pixels (in Chrome the values are truncated, so 50, 50.5 and 50.6 all show the same width).

I had the same issue and solved by following steps below:

1. Go to Xcode Preferences > Accounts > Choose your Apple ID account

2. Tap on View Details

3. Tap on Download all and then Done

However it was working fine earlier but I don't know the reason why it stopped suddenly. I have gone through the steps above and found it working properly.

 <div class="col-md-3 col-sm-3">

    this.colours.push(new Colour(2, 'Pink'));

    this.car = new Car();
    this.car.colour = this.colours[1];        
  }
}

 export class Car

 export class Colour
{
   constructor(id:number, name:string) {
    this.id=id;
    this.name=name;
  }

   id:number;
  name:string;

this is working fine...:)

Although it should be unecessary to do this in anything other than exceptional circumstances, the recommended way to do this on linux hosts is to unload the nvidia driver by doing

$ rmmod nvidia 

with suitable root privileges and then reloading it with

$ modprobe nvidia

If the machine is running X11, you will need to stop this manually beforehand, and restart it afterwards. The driver intialisation processes should eliminate any prior state on the device.

This answer has been assembled from comments and posted as a community wiki to get this question off the unanswered list for the CUDA tag

First you must create an empty figure with the following command.

figure('name','Title of the window here');

By doing this, the newly created figure becomes you active figure. Immediately after calling a plot() command, it will print your plotting onto this figure. So your window will have a title.

This is the code you must use:

figure('name','Title of the window here');

You have to use max-width instead of min-width.

    @media (max-width: 1026px) {

Expanding on AnaPana's answer, how to remove an extension using pathlib (Python >= 3.4):

>>> from pathlib import Path

>>> filename = Path('/some/path/somefile.txt')

>>> filename_wo_ext = filename.with_suffix('')

>>> filename_replace_ext = filename.with_suffix('.jpg')

>>> print(filename)
/some/path/somefile.ext    

>>> print(filename_wo_ext)
/some/path/somefile

>>> print(filename_replace_ext)
/some/path/somefile.jpg

My workaround had been using Perl:

find . -type f -print0 | xargs -0 perl -pi -e 's/was/now/g'

It's a bad idea to count the td elements to get the number of columns in your table, because td elements can span multiple columns with colspan.

Here's a simple solution using jquery:

var length = 0;_x000D_
$("tr:first").find("td,th").each(function(){_x000D_
 var colspan = $(this).attr("colspan");_x000D_
  if(typeof colspan !== "undefined" && colspan > 0){_x000D_
   length += parseInt(colspan);_x000D_
  }else{_x000D_
        length += 1;_x000D_
  }_x000D_
});_x000D_
_x000D_
$("div").html("number of columns: "+length);

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<table>_x000D_
<tr>_x000D_
  <td>single</td>_x000D_
  <td colspan="2">double</td>_x000D_
  <td>single</td>_x000D_
  <td>single</td>_x000D_
</tr>_x000D_

For a plain Javascript solution, see Emilio's answer.

There is an easy way of doing it in Node.js

var object1 = {name: "John"};
var object2 = {location: "San Jose"};

To combine/extend this we can use ... operator in ECMA6

var object1 = {name: "John"};_x000D_
var object2 = {location: "San Jose"};_x000D_
_x000D_
var result = {_x000D_
  ...object1,_x000D_
  ...object2_x000D_
}_x000D_
_x000D_
console.log(result)

You have a dictionary within a list. You must first extract the dictionary from the list and then process the items in the dictionary.

If your list contained multiple dictionaries and you wanted the value from each dictionary stored in a list as you have shown do this:

result_list = [[int(v) for k,v in d.items()] for d in qs]

Which is the same as:

result_list = []
for d in qs:
    result_list.append([int(v) for k,v in d.items()])

The above will keep the values from each dictionary in their own separate list. If you just want all the values in one big list you can do this:

result_list = [int(v) for d in qs for k,v in d.items()]

I was struggling with similar problem (with mail) in one of my git's post_receive hooks and finally I found out, that sendmail actually works better for that kind of things, especially if you know a bit of how e-mails are constructed (and it seems like you know). I know this answer comes very late, but maybe it will be of some use to others too. I made use of heredoc operator and use of the feature, that it expands variables, so it can also run inlined scripts. Just check this out (bash script):

#!/bin/bash
recipients=(
    '[email protected]'
    '[email protected]'
#   '[email protected]'
);
sender='[email protected]';
subject='Oh, who really cares, seriously...';
sendmail -t <<-MAIL
    From: ${sender}
    `for r in "${recipients[@]}"; do echo "To: ${r}"; done;`
    Subject: ${subject}
    Content-Type: text/html; charset=UTF-8

    <html><head><meta charset="UTF-8"/></head>
    <body><p>Ladies and gents, here comes the report!</p>
    <pre>`mysql -u ***** -p***** -H -e "SELECT * FROM users LIMIT 20"`</pre>
    </body></html>
MAIL

Note of backticks in the MAIL part to generate some output and remember, that <<- operator strips only tabs (not spaces) from the beginning of lines, so in that case copy-paste will not work (you need to replace indentation with proper tabs). Or use << operator and make no indentation at all. Hope this will help someone. Of course you can use backticks outside o MAIL part and save the output into some variable, that you can later use in the MAIL part — matter of taste and readability. And I know, #!/bin/bash does not always work on every system.

declare
seprator varchar2(1):=',';
dosweeklist varchar2(4000):='a,b,c';
begin
for i in (SELECT  SUBSTR(dosweeklist,
                         case when level=1 then 1 else INSTR(dosweeklist,seprator,1,LEVEL-1)+1 end,
                         NVL(NULLIF(INSTR(dosweeklist,seprator,1,LEVEL),0),length(dosweeklist)+1) - case when level=1 then 1 else INSTR(dosweeklist,seprator,1,LEVEL-1)+1 end) dat 
          FROM dual
          CONNECT BY LEVEL <= LENGTH(dosweeklist) - LENGTH(REPLACE(dosweeklist,seprator,'')) +1)
loop
dbms_output.put_line(i.dat);
end loop;
end;
/

so select query only in for loop can do the trick, by replacing dosweeklist as your delimited string and seprator as your delimited character.

Lets see output

c

You should use double slash:

var regex = new RegExp("\\?", "g");

Why? because in JavaScript the \ is also used to escape characters in strings, so: "\?" becomes: "?"

And "\\?", becomes "\?"

C++17: Yes! You should use a structured binding declaration. The syntax has been supported in gcc and clang since gcc-7 and clang-4.0 (clang live example). This allows us to unpack a tuple like so:

for (auto [i, f, s] = std::tuple{1, 1.0, std::string{"ab"}}; i < N; ++i, f += 1.5) {
    // ...
}

The above will give you:

• int i set to 1
• double f set to 1.0
• std::string s set to "ab"

Make sure to #include <tuple> for this kind of declaration.

You can specify the exact types inside the tuple by typing them all out as I have with the std::string, if you want to name a type. For example:

auto [vec, i32] = std::tuple{std::vector<int>{3, 4, 5}, std::int32_t{12}}

A specific application of this is iterating over a map, getting the key and value,

std::unordered_map<K, V> m = { /*...*/ };
for (auto& [key, value] : m) {
   // ...
}

See a live example here

C++14: You can do the same as C++11 (below) with the addition of type-based std::get. So instead of std::get<0>(t) in the below example, you can have std::get<int>(t).

C++11: std::make_pair allows you to do this, as well as std::make_tuple for more than two objects.

for (auto p = std::make_pair(5, std::string("Hello World")); p.first < 10; ++p.first) {
    std::cout << p.second << std::endl;
}

std::make_pair will return the two arguments in a std::pair. The elements can be accessed with .first and .second.

For more than two objects, you'll need to use a std::tuple

for (auto t = std::make_tuple(0, std::string("Hello world"), std::vector<int>{});
        std::get<0>(t) < 10;
        ++std::get<0>(t)) {
    std::cout << std::get<1>(t) << std::endl; // cout Hello world
    std::get<2>(t).push_back(std::get<0>(t)); // add counter value to the vector

std::make_tuple is a variadic template that will construct a tuple of any number of arguments (with some technical limitations of course). The elements can be accessed by index with std::get<INDEX>(tuple_object)

Within the for loop bodies you can easily alias the objects, though you still need to use .first or std::get for the for loop condition and update expression

for (auto t = std::make_tuple(0, std::string("Hello world"), std::vector<int>{});
        std::get<0>(t) < 10;
        ++std::get<0>(t)) {
    auto& i = std::get<0>(t);
    auto& s = std::get<1>(t);
    auto& v = std::get<2>(t);
    std::cout << s << std::endl; // cout Hello world
    v.push_back(i); // add counter value to the vector
}

C++98 and C++03 You can explicitly name the types of a std::pair. There is no standard way to generalize this to more than two types though:

for (std::pair<int, std::string> p(5, "Hello World"); p.first < 10; ++p.first) {
    std::cout << p.second << std::endl;
}

Assuming thant the content of mandrill_events is an object (not a string), you can also use shift() function:

var req = { mandrill_events: [{"event":"inbound","ts":1426249238}] };
var event-property = req.mandrill_events.shift().event;

I also got this type error, problem is wrong usage of parameters to statement like, Let's say you have a query like this

SELECT * FROM EMPLOYE E WHERE E.ID = ?

and for the preparedStatement object (JDBC) if you set the parameters like

preparedStatement.setXXX(1,value);
preparedStatement.setXXX(2,value)

then it results in SQLException: Invalid column index

So, I removed that second parameter setting to prepared statement then problem solved

You can design your own Gradient View as follow:

@IBDesignable
public class Gradient: UIView {
    @IBInspectable var startColor:   UIColor = .black { didSet { updateColors() }}
    @IBInspectable var endColor:     UIColor = .white { didSet { updateColors() }}
    @IBInspectable var startLocation: Double =   0.05 { didSet { updateLocations() }}
    @IBInspectable var endLocation:   Double =   0.95 { didSet { updateLocations() }}
    @IBInspectable var horizontalMode:  Bool =  false { didSet { updatePoints() }}
    @IBInspectable var diagonalMode:    Bool =  false { didSet { updatePoints() }}

    override public class var layerClass: AnyClass { CAGradientLayer.self }

    var gradientLayer: CAGradientLayer { layer as! CAGradientLayer }

    func updatePoints() {
        if horizontalMode {
            gradientLayer.startPoint = diagonalMode ? .init(x: 1, y: 0) : .init(x: 0, y: 0.5)
            gradientLayer.endPoint   = diagonalMode ? .init(x: 0, y: 1) : .init(x: 1, y: 0.5)
        } else {
            gradientLayer.startPoint = diagonalMode ? .init(x: 0, y: 0) : .init(x: 0.5, y: 0)
            gradientLayer.endPoint   = diagonalMode ? .init(x: 1, y: 1) : .init(x: 0.5, y: 1)
        }
    }
    func updateLocations() {
        gradientLayer.locations = [startLocation as NSNumber, endLocation as NSNumber]
    }
    func updateColors() {
        gradientLayer.colors = [startColor.cgColor, endColor.cgColor]
    }
    override public func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
        super.traitCollectionDidChange(previousTraitCollection)
        updatePoints()
        updateLocations()
        updateColors()
    }

git mv moves the file, updating the index to record the replaced file path, as well as updating any affected git submodules. Unlike a manual move, it also detects case-only renames that would not otherwise be detected as a change by git.

It is similar (though not identical) in behavior to moving the file externally to git, removing the old path from the index using git rm, and adding the new one to the index using git add.

Answer Motivation

This question has a lot of great partial answers. This answer is an attempt to combine them into a single cohesive answer. Additionally, one thing not called out by any of the other answers is the fact that the man page actually does mostly answer the question, but it's perhaps less obvious than it could be.

Detailed Explanation

Three different effects are called out in the man page:

1. The file, directory, or symlink is moved in the filesystem:

   git-mv - Move or rename a file, a directory, or a symlink

2. The index is updated, adding the new path and removing the previous one:

   The index is updated after successful completion, but the change must still be committed.

3. Moved submodules are updated to work at the new location:

   Moving a submodule using a gitfile (which means they were cloned with a Git version 1.7.8 or newer) will update the gitfile and core.worktree setting to make the submodule work in the new location. It also will attempt to update the submodule.<name>.path setting in the gitmodules(5) file and stage that file (unless -n is used).

As mentioned in this answer, git mv is very similar to moving the file, adding the new path to the index, and removing the previous path from the index:

mv oldname newname
git add newname
git rm oldname

However, as this answer points out, git mv is not strictly identical to this in behavior. Moving the file via git mv adds the new path to the index, but not any modified content in the file. Using the three individual commands, on the other hand, adds the entire file to the index, including any modified content. This could be relevant when using a workflow which patches the index, rather than adding all changes in the file.

Additionally, as mentioned in this answer and this comment, git mv has the added benefit of handling case-only renames on file systems that are case-insensitive but case-preserving, as is often the case in current macOS and Windows file systems. For example, in such systems, git would not detect that the file name has changed after moving a file via mv Mytest.txt MyTest.txt, whereas using git mv Mytest.txt MyTest.txt would successfully update its name.

This error comes when there's incompatibility between node version and angular/cli version. therefore use below command to update the cli version to latest

npm install -g @angular/cli@latest

Folks,

I ran into a similar issue. But using Fiddler, I was able to get at the issue. The problem is that the client URL that is configured in the CORS implementation on the Web API side must not have a trailing forward-slash. After submitting your request via Google Chrome and inspect the TextView tab of the Headers section of Fiddler, the error message states something like this:

*"The specified policy origin your_client_url:/' is invalid. It cannot end with a forward slash."

This is real quirky because it worked without any issues on Internet Explorer, but gave me a headache when testing using Google Chrome.

I removed the forward-slash in the CORS code and recompiled the Web API, and now the API is accessible via Chrome and Internet Explorer without any issues. Please give this a shot.

Thanks, Andy

Remove all wsdl* files in your /tmp folder on the server.

WSDL files are cached in your default location for all cache files defined in php.ini. Same location as your session files.

You can do it like this:

I have a folder named utilities and inside that I have a file named _variables.scss

in that file i declare variables like so:

$black: #000;
$white: #fff;

then I have the style.scss file in which i import all of my other scss files like this:

// Utilities
@import "utilities/variables";

// Base Rules
@import "base/normalize";
@import "base/global";

then, within any of the files I have imported, I should be able to access the variables I have declared.

Just make sure you import the variable file before any of the others you would like to use it in.

On centOS7 I changed the file /etc/httpd/conf/httpd.conf

from AllowOverride None to AllowOverride All

Moment.js stores dates it utc and can apply different timezones to it. By default it applies your local timezone. If you want to set time on utc date time you need to specify utc timezone.

Try the following code:

var m = moment().utcOffset(0);
m.set({hour:0,minute:0,second:0,millisecond:0})
m.toISOString()
m.format()

@jellyfishtree it would be a better if you create one php file which includes all your js files from the directory and then only include this php file via a script tag. This has a better performance because the browser has to do less requests to the server. See this:

javascripts.php:

<?php
   //sets the content type to javascript 
   header('Content-type: text/javascript');

   // includes all js files of the directory
   foreach(glob("packages/*.js") as $file) {
      readfile($file);
   }
?>

index.php:

<script type="text/javascript" src="javascripts.php"></script>

That's it!
Have fun! :)

sorry for answering in old thread but may my code helps other in future.i was in same scenario that when check box will be checked then few selected inputs fields will be enable other wise disabled.

$("[id*='chkAddressChange']").click(function () {
    var checked = $(this).is(':checked');
    if (checked) {
        $('.DisabledInputs').removeAttr('disabled');
    } else {
        $('.DisabledInputs').attr('disabled', 'disabled');
    }
});

getActionCommand()

Returns the command string associated with this action. This string allows a "modal" component to specify one of several commands, depending on its state. For example, a single button might toggle between "show details" and "hide details". The source object and the event would be the same in each case, but the command string would identify the intended action.

IMO, this is useful in case you a single command-component to fire different commands based on it's state, and using this method your handler can execute the right lines of code.

JTextField has JTextField#setActionCommand(java.lang.String) method that you can use to set the command string used for action events generated by it.

getSource()

Returns: The object on which the Event initially occurred.

We can use getSource() to identify the component and execute corresponding lines of code within an action-listener. So, we don't need to write a separate action-listener for each command-component. And since you have the reference to the component itself, you can if you need to make any changes to the component as a result of the event.

If the event was generated by the JTextField then the ActionEvent#getSource() will give you the reference to the JTextField instance itself.

try this command, xcopy c:\ (file or directory path) F:\ /e. If you want more details refer this site [[http://www.computerhope.com/xcopyhlp.htm]]

You can access the keys with ${!array[@]}:

bash-4.0$ echo "${!array[@]}"
foo bar

Then, iterating over the key/value pairs is easy:

for i in "${!array[@]}"
do
  echo "key :" $i
  echo "value:" ${array[$i]}
done

If you want to check contents are equal or not then just use JSON.stringify(obj)

Eg - var a ={key:val};

var b ={key:val};

JSON.stringify(a) == JSON.stringify(b) -----> If contents are same you gets true.

This should be more efficient both for the application and also for the developer.

Add the following class to your web project:

/// <summary>
/// This holds all of the session variables for the site.
/// </summary>
public class SessionCentralized
{
protected internal static void Save<T>(string sessionName, T value)
{
    HttpContext.Current.Session[sessionName] = value;
}

protected internal static T Get<T>(string sessionName)
{
    return (T)HttpContext.Current.Session[sessionName];
}

public static int? WhatEverSessionVariableYouWantToHold
{
    get
    {
        return Get<int?>(nameof(WhatEverSessionVariableYouWantToHold));
    }
    set
    {
        Save(nameof(WhatEverSessionVariableYouWantToHold), value);
    }
}

}

Here is the implementation:

SessionCentralized.WhatEverSessionVariableYouWantToHold = id;

One of the significant difference I found out which surprisingly no-one has talked about is that using plain import you can access private variable and private functions from the imported module, which isn't possible with from-import statement.

Code in image:

setting.py

public_variable = 42
_private_variable = 141
def public_function():
    print("I'm a public function! yay!")
def _private_function():
    print("Ain't nobody accessing me from another module...usually")

plain_importer.py

import settings
print (settings._private_variable)
print (settings.public_variable)
settings.public_function()
settings._private_function()

# Prints:
# 141
# 42
# I'm a public function! yay!
# Ain't nobody accessing me from another module...usually

from_importer.py

from settings import *
#print (_private_variable) #doesn't work
print (public_variable)
public_function()
#_private_function()   #doesn't work

I only see one color being specified (albeit you specify it in two different places.) Either you've omitted some of your style rules, or you simply didn't specify another color.

I agree with @kent that this is well suited for grep -o. If you need to extract a group within a pattern, you can do it with a 2nd grep.

# To extract \1 from /xx([0-9]+)yy/
$ echo "aa678bb xx123yy xx4yy aa42 aa9bb" | grep -Eo 'xx[0-9]+yy' | grep -Eo '[0-9]+'
123
4

# To extract \1 from /a([0-9]+)b/
$ echo "aa678bb xx123yy xx4yy aa42 aa9bb" | grep -Eo 'a[0-9]+b' | grep -Eo '[0-9]+'
678
9

I generally cringe when I see 2 calls to grep/sed/awk piped together, but it's not always wrong. While we should exercise our skills of doing things efficiently, "A foolish consistency is the hobgoblin of little minds", and "Real artists ship".

The Response API consumes a (immutable) Blob from which the data can be retrieved in several ways. The OP only asked for ArrayBuffer, and here's a demonstration of it.

var blob = GetABlobSomehow();

// NOTE: you will need to wrap this up in a async block first.
/* Use the await keyword to wait for the Promise to resolve */
await new Response(blob).arrayBuffer();   //=> <ArrayBuffer>

alternatively you could use this:

new Response(blob).arrayBuffer()
.then(/* <function> */);

Note: This API isn't compatible with older (ancient) browsers so take a look to the Browser Compatibility Table to be on the safe side ;)

You need a table variable and it can be this simple.

declare @ID table (ID int)

insert into MyTable2(ID)
output inserted.ID into @ID
values (1)

this my solution: json string $columns_validation = string(1736) "[{"colId":"N_ni","hide":true,"aggFunc":null,"width":136,"pivotIndex":null,"pinned":null,"rowGroupIndex":null},{"colId":"J_2_fait","hide":true,"aggFunc":null,"width":67,"pivotIndex":null,"pinned":null,"rowGroupIndex":null}]"

so i use json_decode twice like that :

$js_column_validation = json_decode($columns_validation);
$js_column_validation = json_decode($js_column_validation); 

var_dump($js_column_validation);

and the result is :

 array(15) { [0]=> object(stdClass)#23 (7) { ["colId"]=> string(4) "N_ni" ["hide"]=> bool(true) ["aggFunc"]=> NULL ["width"]=> int(136) ["pivotIndex"]=> NULL ["pinned"]=> NULL ["rowGroupIndex"]=> NULL } [1]=> object(stdClass)#2130 (7) { ["colId"]=> string(8) "J_2_fait" ["hide"]=> bool(true) ["aggFunc"]=> NULL ["width"]=> int(67) ["pivotIndex"]=> NULL ["pinned"]=> NULL ["rowGroupIndex"]=> NULL }

We are using the following procedure, it allows us to re-create a type from scratch, which is "a start". It renames the existing type, creates the type, recompiles stored procs and then drops the old type. This takes care of scenarios where simply dropping the old type-definition fails due to references to that type.

Usage Example:

exec RECREATE_TYPE @schema='dbo', @typ_nme='typ_foo', @sql='AS TABLE([bar] varchar(10) NOT NULL)'

Code:

CREATE PROCEDURE [dbo].[RECREATE_TYPE]
    @schema     VARCHAR(100),       -- the schema name for the existing type
    @typ_nme    VARCHAR(128),       -- the type-name (without schema name)
    @sql        VARCHAR(MAX)        -- the SQL to create a type WITHOUT the "CREATE TYPE schema.typename" part
AS DECLARE
    @scid       BIGINT,
    @typ_id     BIGINT,
    @temp_nme   VARCHAR(1000),
    @msg        VARCHAR(200)
BEGIN
    -- find the existing type by schema and name
    SELECT @scid = [SCHEMA_ID] FROM sys.schemas WHERE UPPER(name) = UPPER(@schema);
    IF (@scid IS NULL) BEGIN
        SET @msg = 'Schema ''' + @schema + ''' not found.';
        RAISERROR (@msg, 1, 0);
    END;
    SELECT @typ_id = system_type_id FROM sys.types WHERE UPPER(name) = UPPER(@typ_nme);
    SET @temp_nme = @typ_nme + '_rcrt'; -- temporary name for the existing type

    -- if the type-to-be-recreated actually exists, then rename it (give it a temporary name)
    -- if it doesn't exist, then that's OK, too.
    IF (@typ_id IS NOT NULL) BEGIN
        exec sp_rename @objname=@typ_nme, @newname= @temp_nme, @objtype='USERDATATYPE'
    END;    

    -- now create the new type
    SET @sql = 'CREATE TYPE ' + @schema + '.' + @typ_nme + ' ' + @sql;
    exec sp_sqlexec @sql;

    -- if we are RE-creating a type (as opposed to just creating a brand-spanking-new type)...
    IF (@typ_id IS NOT NULL) BEGIN
        exec recompile_prog;    -- then recompile all stored procs (that may have used the type)
        exec sp_droptype @typename=@temp_nme;   -- and drop the temporary type which is now no longer referenced
    END;    
END

Try a MaskedTextBox. It takes a simple mask format so you can limit the input to numbers or dates or whatever.

For the absolute coordinates of any jquery element I wrote this function, it probably doesnt work for all css position types but maybe its a good start for someone ..

function AbsoluteCoordinates($element) {
    var sTop = $(window).scrollTop();
    var sLeft = $(window).scrollLeft();
    var w = $element.width();
    var h = $element.height();
    var offset = $element.offset(); 
    var $p = $element;
    while(typeof $p == 'object') {
        var pOffset = $p.parent().offset();
        if(typeof pOffset == 'undefined') break;
        offset.left = offset.left + (pOffset.left);
        offset.top = offset.top + (pOffset.top);
        $p = $p.parent();
    }

    var pos = {
          left: offset.left + sLeft,
          right: offset.left + w + sLeft,
          top:  offset.top + sTop,
          bottom: offset.top + h + sTop,
    }
    pos.tl = { x: pos.left, y: pos.top };
    pos.tr = { x: pos.right, y: pos.top };
    pos.bl = { x: pos.left, y: pos.bottom };
    pos.br = { x: pos.right, y: pos.bottom };
    //console.log( 'left: ' + pos.left + ' - right: ' + pos.right +' - top: ' + pos.top +' - bottom: ' + pos.bottom  );
    return pos;
}

Just include the path to the view, with the file extension.

Razor:

@Html.Partial("~/Views/AnotherFolder/Messages.cshtml", ViewData.Model.Successes)

ASP.NET engine:

<% Html.RenderPartial("~/Views/AnotherFolder/Messages.ascx", ViewData.Model.Successes); %>

If that isn't your issue, could you please include your code that used to work with the RenderUserControl?

This is how I solved it. I forgot that sublist was a direct reference to the elements in the original list, so it makes sense why it wouldn't work.

ArrayList<Integer> inputA = new ArrayList<Integer>(input.subList(0, input.size()/2));

In javascript you can do:

var element = document.getElementById("myid");
element.style.position = "fixed";
element.style.top = "0%";

For me, it was a missing app domain. Go into the app, and make sure that you have the root of your site set up as an app domain. See screenshot.

You can execute it just as you select a table using SELECT clause. In addition you can provide parameters within parentheses.

Try with below syntax:

SELECT * FROM yourFunctionName(parameter1, parameter2)

Try this one:

echo date('m/d/Y H:i:s', 1541843467);

You're missing comma (,) inbetween:

>>> ((1,2) (2,3))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'tuple' object is not callable

Put comma:

>>> ((1,2), (2,3))
((1, 2), (2, 3))

You can use a concept that is frequently referred to as 'calendar tables'. Here is a good guide on how to create calendar tables in MySql:

-- create some infrastructure
CREATE TABLE ints (i INTEGER);
INSERT INTO ints VALUES (0), (1), (2), (3), (4), (5), (6), (7), (8), (9);

-- only works for 100 days, add more ints joins for more
SELECT cal.date, tbl.data
FROM (
    SELECT '2009-06-25' + INTERVAL a.i * 10 + b.i DAY as date
    FROM ints a JOIN ints b
    ORDER BY a.i * 10 + b.i
) cal LEFT JOIN tbl ON cal.date = tbl.date
WHERE cal.date BETWEEN '2009-06-25' AND '2009-07-01';

You might want to create table cal instead of the subselect.

Validating email is a very important point while validating an HTML form. In this page we have discussed how to validate an email using JavaScript :

An email is a string (a subset of ASCII characters) separated into two parts by @ symbol. a "personal_info" and a domain, that is personal_info@domain. The length of the personal_info part may be up to 64 characters long and domain name may be up to 253 characters. The personal_info part contains the following ASCII characters.

1. Uppercase (A-Z) and lowercase (a-z) English letters.
2. Digits (0-9).
3. Characters ! # $ % & ' * + - / = ? ^ _ ` { | } ~
4. Character . ( period, dot or fullstop) provided that it is not the first or last character and it will not come one after the other.

The domain name [for example com, org, net, in, us, info] part contains letters, digits, hyphens, and dots.

Example of valid email id

[email protected]

[email protected]

[email protected]

Example of invalid email id

mysite.ourearth.com [@ is not present]

[email protected] [ tld (Top Level domain) can not start with dot "." ]

@you.me.net [ No character before @ ]

[email protected] [ ".b" is not a valid tld ]

[email protected] [ tld can not start with dot "." ]

[email protected] [ an email should not be start with "." ]

mysite()*@gmail.com [ here the regular expression only allows character, digit, underscore, and dash ]

[email protected] [double dots are not allowed]

JavaScript code to validate an email id

function ValidateEmail(mail) {
        if (/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w {2, 3})+$/.test(myForm.emailAddr.value)) {
            return (true)
        }
        alert("You have entered an invalid email address!")
        return (false)
    }

It'll be easier (and more "proper", see below) if you just run your script as

myprogram /path/to/file

Then you can access the path within the script as $1 (for argument #1, similarly $2 is argument #2, etc.)

file="$1"
externalprogram "$file" [other parameters]

Or just

externalprogram "$1" [otherparameters]

If you want to extract the path from something like --file=/path/to/file, that's usually done with the getopts shell function. But that's more complicated than just referencing $1, and besides, switches like --file= are intended to be optional. I'm guessing your script requires a file name to be provided, so it doesn't make sense to pass it in an option.

Just an update.

The present TiKZ package will issue: Package tikz Warning: Snakes have been superseded by decorations. Please use the decoration libraries instead of the snakes library on input line. . .

I tried all suggested ways from this question answers and other articles in the web but not working anyway. I tried autocomplete="new-random-value", autocomplete="off" in form element, using client-side script as below but outside of $(document).ready() as one of the user mentioned:

$(':input').on('focus', function () {
  $(this).attr('autocomplete', 'off')
});

I found maybe another priority in the browser cause this weird behavior! So I searched more and finally, I read again carefully below lines from this good article:

For this reason, many modern browsers do not support autocomplete="off" for login fields:

If a site sets autocomplete="off" for a , and the form includes username and password input fields, then the browser will still offer to remember this login, and if the user agrees, the browser will autofill those fields the next time the user visits the page. If a site sets autocomplete="off" for username and password fields, then the browser will still offer to remember this login, and if the user agrees, the browser will autofill those fields the next time the user visits the page. This is the behavior in Firefox (since version 38), Google Chrome (since 34), and Internet Explorer (since version 11).

If you are defining a user management page where a user can specify a new password for another person, and therefore you want to prevent auto-filling of password fields, you can use autocomplete="new-password"; however, support for this value has not been implemented on Firefox.

It's just worked. I tried in chrome specially and I hope this continues working and help others.

You want the (standard) POSIXt type from base R that can be had in 'compact form' as a POSIXct (which is essentially a double representing fractional seconds since the epoch) or as long form in POSIXlt (which contains sub-elements). The cool thing is that arithmetic etc are defined on this -- see help(DateTimeClasses)

Quick example:

R> now <- Sys.time()
R> now
[1] "2009-12-25 18:39:11 CST"
R> as.numeric(now)
[1] 1.262e+09
R> now + 10  # adds 10 seconds
[1] "2009-12-25 18:39:21 CST"
R> as.POSIXlt(now)
[1] "2009-12-25 18:39:11 CST"
R> str(as.POSIXlt(now))
 POSIXlt[1:9], format: "2009-12-25 18:39:11"
R> unclass(as.POSIXlt(now))
$sec
[1] 11.79

$min
[1] 39

$hour
[1] 18

$mday
[1] 25

$mon

$year

$yday

As for reading them in, see help(strptime)

As for difference, easy too:

R> Jan1 <- strptime("2009-01-01 00:00:00", "%Y-%m-%d %H:%M:%S")
R> difftime(now, Jan1, unit="week")
Time difference of 51.25 weeks

Lastly, the zoo package is an extremely versatile and well-documented container for matrix with associated date/time indices.

That should be possible using Socket.IO-client: https://github.com/LearnBoost/socket.io-client

use:

std::vector <Acard> playerHand;

everywhere qualify it by std::

or do:

using std::vector;

in your cpp file.

You have to do this because vector is defined in the std namespace and you do not tell your program to find it in std namespace, you need to tell that.

Well, this is another solution that some of you guys might be looking for (as I was..)

My problem was similar, the modal box was closing while the iframe I had inside was loading, so I had to disable the modal dismiss until the Iframe finishes loading, then re-enable.

The solutions presented here were not working 100%.

My solution was this:

showLocationModal = function(loc){

    var is_loading = true;

    if(is_loading === true) {

        is_loading  = false;
        var $modal   = $('#locationModal');

        $modal.modal({show:true});

        // prevent Modal to close before the iframe is loaded
        $modal.on("hide", function (e) {
            if(is_loading !== true) {
                e.preventDefault();
                return false
            }
        });

        // populate Modal
        $modal.find('.modal-body iframe').hide().attr('src', location.link).load(function(){

            is_loading = true;
     });
}};

So I temporarily prevent the Modal from closing with:

$modal.on("hide", function (e) {
    if(is_loading !== true) {
        e.preventDefault();
        return false
    }
});

But ith the var is_loading that will re enable closing after the Iframe has loaded.

So the problem with a lot of these solutions is you're assuming the window appears instantly (nothing happens instantly, and things happen significantly less instantly in IE). Also you're assuming that there will only be one window prior to clicking the element, which is not always the case. Also IE will not return the window handles in a predictable order. So I would do the following.

 public String clickAndSwitchWindow(WebElement elementToClick, Duration 
    timeToWaitForWindowToAppear) {
    Set<String> priorHandles = _driver.getWindowHandles();

    elementToClick.click();
    try {
        new WebDriverWait(_driver,
                timeToWaitForWindowToAppear.getSeconds()).until(
                d -> {
                    Set<String> newHandles = d.getWindowHandles();
                    if (newHandles.size() > priorHandles.size()) {
                        for (String newHandle : newHandles) {
                            if (!priorHandles.contains(newHandle)) {
                                d.switchTo().window(newHandle);
                                return true;
                            }
                        }
                        return false;
                    } else {
                        return false;
                    }

                });
    } catch (Exception e) {
        Logging.log_AndFail("Encountered error while switching to new window after clicking element " + elementToClick.toString()
                + " seeing error: \n" + e.getMessage());
    }

    return _driver.getWindowHandle();
}

I always make a call from the end of the JavaScript files for registering its loading and it used to work perfect for me for all the browsers.

Ex: I have an index.htm, Js1.js and Js2.js. I add the function IAmReady(Id) in index.htm header and call it with parameters 1 and 2 from the end of the files, Js1 and Js2 respectively. The IAmReady function will have a logic to run the boot code once it gets two calls (storing the the number of calls in a static/global variable) from the two js files.

If you don't have any other indexes or sorted information for your objects, then you will have to iterate until such an object is found:

next(obj for obj in objs if obj.val == 5)

This is however faster than a complete list comprehension. Compare these two:

[i for i in xrange(100000) if i == 1000][0]

next(i for i in xrange(100000) if i == 1000)

The first one needs 5.75ms, the second one 58.3µs (100 times faster because the loop 100 times shorter).

This is what I used to set it:

$("body").on('touchmove', function(e){ 
    e.preventDefault(); 
});

And to undo it:

$("body").unbind("touchmove");

This is a well-known issue and based on this answer you could add setLenient:

Gson gson = new GsonBuilder()
        .setLenient()
        .create();

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(BASE_URL)
        .client(client)
        .addConverterFactory(GsonConverterFactory.create(gson))
        .build();

Now, if you add this to your retrofit, it gives you another error:

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $

This is another well-known error you can find answer here (this error means that your server response is not well-formatted); So change server response to return something:

{
    android:[
        { ver:"1.5", name:"Cupcace", api:"Api Level 3" }
        ...
    ]
}

For better comprehension, compare your response with Github api.

Suggestion: to find out what's going on to your request/response add HttpLoggingInterceptor in your retrofit.

Based on this answer your ServiceHelper would be:

private ServiceHelper() {
        httpClient = new OkHttpClient.Builder();
        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        httpClient.interceptors().add(interceptor);
        Retrofit retrofit = createAdapter().build();
        service = retrofit.create(IService.class);
    }

Also don't forget to add:

compile 'com.squareup.okhttp3:logging-interceptor:3.3.1'

It depends on whether the question you are asking is:

1. Are these two structs the same object?
2. Do they have the same value?

To find out if they are the same object, compare pointers to the two structs for equality. If you want to find out in general if they have the same value you have to do a deep comparison. This involves comparing all the members. If the members are pointers to other structs you need to recurse into those structs too.

In the special case where the structs do not contain pointers you can do a memcmp to perform a bitwise comparison of the data contained in each without having to know what the data means.

Make sure you know what 'equals' means for each member - it is obvious for ints but more subtle when it comes to floating-point values or user-defined types.

You have done it backwards, it should be:

amount = invest(amount,top_company(5,year,year+1),year)

It's because val is not null, but contains 'null' as a string.

Try to check with 'null'

if ('null' != val)

For an explanation of when and why this works, see the details below.

As of the time of this writing, Swift natively supports comparing Dates with all comparison operators (i.e. <, <=, ==, >=, and >). You can also compare optional Dates but are limited to <, ==, and >. If you need to compare two optional dates using <= or >=, i.e.

let date1: Date? = ...
let date2: Date? = ...
if date1 >= date2 { ... }

You can overload the <= and >=operators to support optionals:

func <= <T: Comparable>(lhs: T?, rhs: T?) -> Bool {
    return lhs == rhs || lhs < rhs
}

func >= <T: Comparable>(lhs: T?, rhs: T?) -> Bool {
    return lhs == rhs || lhs > rhs
}

It depends on what you mean:

• As mentioned String.hashCode() gives you a 32 bit hash code.

• If you want (say) a 64-bit hashcode you can easily implement it yourself.

• If you want a cryptographic hash of a String, the Java crypto libraries include implementations of MD5, SHA-1 and so on. You'll typically need to turn the String into a byte array, and then feed that to the hash generator / digest generator. For example, see @Bryan Kemp's answer.

• If you want a guaranteed unique hash code, you are out of luck. Hashes and hash codes are non-unique.

A Java String of length N has 65536 ^ N possible states, and requires an integer with 16 * N bits to represent all possible values. If you write a hash function that produces integer with a smaller range (e.g. less than 16 * N bits), you will eventually find cases where more than one String hashes to the same integer; i.e. the hash codes cannot be unique. This is called the Pigeonhole Principle, and there is a straight forward mathematical proof. (You can't fight math and win!)

But if "probably unique" with a very small chance of non-uniqueness is acceptable, then crypto hashes are a good answer. The math will tell you how big (i.e. how many bits) the hash has to be to achieve a given (low enough) probability of non-uniqueness.

You have to know what is your Entity-Framework version. Also after that you have to check project.json and control these sections:

In Dependencies

check:

Microsoft.EntityFrameworkCore.Tools": {
  "version": "1.0.0-preview2-final",
  "type": "build"
},

This section:

"version": "1.0.0-preview2-final",

is related with version of your Entity-Framework and you have to change this with that.

After that the second section of the proj.json is here, In the Tools section of JSON you have:

"Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final",

Also this part of code is related with your Entity-Framework and last part of code in Dependencies section.

Note: After do this issues you should to close CMD and restart visual studio.

 $('mainCheckBox').click(function(){
    if($(this).prop('checked')){
        $('Id or Class of checkbox').prop('checked', true);
    }else{
        $('Id or Class of checkbox').prop('checked', false);
    }
});

WSDL: Stands for Web Service Description Language

In SOAP(simple object access protocol), when you use web service and add a web service to your project, your client application(s) doesn't know about web service Functions. Nowadays it's somehow old-fashion and for each kind of different client you have to implement different WSDL files. For example you cannot use same file for .Net and php client. The WSDL file has some descriptions about web service functions. The type of this file is XML. SOAP is an alternative for REST.

REST: Stands for Representational State Transfer

It is another kind of API service, it is really easy to use for clients. They do not need to have special file extension like WSDL files. The CRUD operation can be implemented by different HTTP Verbs(GET for Reading, POST for Creation, PUT or PATCH for Updating and DELETE for Deleting the desired document) , They are based on HTTP protocol and most of times the response is in JSON or XML format. On the other hand the client application have to exactly call the related HTTP Verb via exact parameters names and types. Due to not having special file for definition, like WSDL, it is a manually job using the endpoint. But it is not a big deal because now we have a lot of plugins for different IDEs to generating the client-side implementation.

SOA: Stands for Service Oriented Architecture

Includes all of the programming with web services concepts and architecture. Imagine that you want to implement a large-scale application. One practice can be having some different services, called micro-services and the whole application mechanism would be calling needed web service at the right time. Both REST and SOAP web services are kind of SOA.

JSON: Stands for javascript Object Notation

when you serialize an object for javascript the type of object format is JSON. imagine that you have the human class :

class Human{
 string Name;
 string Family;
 int Age;
}

and you have some instances from this class :

Human h1 = new Human(){
  Name='Saman',
  Family='Gholami',
  Age=26
}

when you serialize the h1 object to JSON the result is :

  [h1:{Name:'saman',Family:'Gholami',Age:'26'}, ...]

javascript can evaluate this format by eval() function and make an associative array from this JSON string. This one is different concept in comparison to other concepts I described formerly.

if you provide a bad path or a broken link, if the compiler cannot find the image, the picture box would display an X icon on its body.

PictureBox picture = new PictureBox
        {
            Name = "pictureBox",
            Size = new Size(100, 50),
            Location = new Point(14, 17),
            Image = Image.FromFile(@"c:\Images\test.jpg"),
            SizeMode = PictureBoxSizeMode.CenterImage
        };
p.Controls.Add(picture);

OR

PictureBox picture = new PictureBox
        {
            Name = "pictureBox",
            Size = new Size(100, 50),
            Location = new Point(14, 17),
            ImageLocation = @"c:\Images\test.jpg",
            SizeMode = PictureBoxSizeMode.CenterImage
        };
p.Controls.Add(picture);

i'm not sure where you put images in your folder structure but you can find the path as bellow

 picture.ImageLocation = Path.Combine(System.Windows.Forms.Application.StartupPath, "Resources\Images\1.jpg");

This is badly formed HTML. You need to either have a single id or space separated classes. Either way if you're new I'd look into jQuery.

<div id="sub1">some text</div>

or

<div class="sub1 sub2 sub3">some text</div>

If you had the following HTML:

<div id="sub1">some text</div>
<div id="welcome" style="display:none;">Some welcome message</div>

jQuery

$(document).ready(function() {
    $('#sub1').hover(
      function() { $('#welcome').show(); },
      function() { $('#welcome').hide(); }
    );
});

Javascript

you'd probably want to include the events on your html:

<div id="sub1" onmouseover="showWelcome();" onmouseout="hideWelcome();">some text</div>

then your javascript would have these two functions

function showWelcome()
{
   var welcome = document.getElementById('welcome');
   welcome.style.display = 'block';
}

function hideWelcome()
{
   var welcome = document.getElementById('welcome');
   welcome.style.display = 'none';
}

Please note: this javascript doesn't take cross browser issues into consideration. for this you'd need to elaborate on your code, just another reason to use jquery.

None of these answers achieved what I was looking for, so I wound up writing something myself. I wanted to pinch-zoom an image on my website using my MacBookPro trackpad. The following code (which requires jQuery) seems to work in Chrome and Edge, at least. Maybe this will be of use to someone else.

function setupImageEnlargement(el)
{
    // "el" represents the image element, such as the results of document.getElementByd('image-id')
    var img = $(el);
    $(window, 'html', 'body').bind('scroll touchmove mousewheel', function(e)
    {
        //TODO: need to limit this to when the mouse is over the image in question

        //TODO: behavior not the same in Safari and FF, but seems to work in Edge and Chrome

        if (typeof e.originalEvent != 'undefined' && e.originalEvent != null
            && e.originalEvent.wheelDelta != 'undefined' && e.originalEvent.wheelDelta != null)
        {
            e.preventDefault();
            e.stopPropagation();
            console.log(e);
            if (e.originalEvent.wheelDelta > 0)
            {
                // zooming
                var newW = 1.1 * parseFloat(img.width());
                var newH = 1.1 * parseFloat(img.height());
                if (newW < el.naturalWidth && newH < el.naturalHeight)
                {
                    // Go ahead and zoom the image
                    //console.log('zooming the image');
                    img.css(
                    {
                        "width": newW + 'px',
                        "height": newH + 'px',
                        "max-width": newW + 'px',
                        "max-height": newH + 'px'
                    });
                }
                else
                {
                    // Make image as big as it gets
                    //console.log('making it as big as it gets');
                    img.css(
                    {
                        "width": el.naturalWidth + 'px',
                        "height": el.naturalHeight + 'px',
                        "max-width": el.naturalWidth + 'px',
                        "max-height": el.naturalHeight + 'px'
                    });
                }
            }
            else if (e.originalEvent.wheelDelta < 0)
            {

                var newW = 0.9 * parseFloat(img.width());
                var newH = 0.9 * parseFloat(img.height());

                //TODO: I had added these data-attributes to the image onload.
                // They represent the original width and height of the image on the screen.
                // If your image is normally 100% width, you may need to change these values on resize.
                var origW = parseFloat(img.attr('data-startwidth'));
                var origH = parseFloat(img.attr('data-startheight'));

                if (newW > origW && newH > origH)
                {
                    // Go ahead and shrink the image

                        "max-width": newW + 'px',
                        "max-height": newH + 'px'

1. Visual Studio 2010 Professional SP1.
2. .NET Framework 4 Client Profile.
3. PNG image added as resource on project properties.
4. New file in Resources folder automatically created.
5. Build action set to resource.

This worked for me:

<BitmapImage x:Key="MyImageSource" UriSource="Resources/Image.png" />

Precision and scale are often misunderstood. In numeric(3,2) you want 3 digits overall, but 2 to the right of the decimal. If you want 15 => 15.00 so the leading 1 causes the overflow (since if you want 2 digits to the right of the decimal, there is only room on the left for one more digit). With 4,2 there is no problem because all 4 digits fit.

The problem can also be the ordering of your style sheet imports. I had to move my custom style sheet import below the bootstrap import.

I wanted to set a specific date so have used this to do stuff before 2nd December 2013

if(mktime(0,0,0,12,2,2013) > strtotime('now')) {
    // do stuff
}

The 0,0,0 is midnight, the 12 is the month, the 2 is the day and the 2013 is the year.

For triggering any event in Javascript.

 document.getElementById("yourid").addEventListener("change", function({
    //your code here
})

The issue is that you branched off a branch off of.... where you are trying to rebase to. You can't rebase to a branch that does not contain the commit your current branch was originally created on.

I got this when I first rebased a local branch X to a pushed one Y, then tried to rebase a branch (first created on X) to the pushed one Y.

Solved for me by rebasing to X.

I have no problem rebasing to remote branches (potentially not even checked out), provided my current branch stems from an ancestor of that branch.

Justin's answer did not work for me (Chromium 18, Firefox 43.0.1). jQuery's .focus() creates visual highlight, but text cursor does not appear in the field (jquery 3.1.0).

Inspired by https://www.sitepoint.com/jqueryhtml5-input-focus-cursor-positions/ , I added autofocus attribute to the input field and voila!

function addfield() {
    n=$('table tr').length;
    $('table').append('<tr><td><input name=field'+n+' autofocus></td><td><input name=value'+n+'></td></tr>');
    $('input[name="aa"'+n+']').focus();
}

As javascript is dynamically typed, rather than using the .length property as above you can simply treat the input value as a boolean:

var input = $.trim($("#spa").val());

if (input) {
    // Do Stuff
}

You can also extract the logic out into functions, then by assigning a class and using the each() method the code is more dynamic if, for example, in the future you wanted to add another input you wouldn't need to change any code.

So rather than hard coding the function call into the input markup, you can give the inputs a class, in this example it's test, and use:

$(".test").each(function () {
    $(this).keyup(function () {
        $("#submit").prop("disabled", CheckInputs());
    });
});

which would then call the following and return a boolean value to assign to the disabled property:

function CheckInputs() {
    var valid = false;
    $(".test").each(function () {
        if (valid) { return valid; }
        valid = !$.trim($(this).val());
    });
    return valid;
}

You can see a working example of everything I've mentioned in this JSFiddle.

For ICS I´ve implemented your code and made a class that extends AsyncTask. I hope you appreciate it! Thanks for your code and solution.

public class UpdateApp extends AsyncTask<String,Void,Void>{
    private Context context;
    public void setContext(Context contextf){
        context = contextf;
    }

    @Override
    protected Void doInBackground(String... arg0) {
        try {
            URL url = new URL(arg0[0]);
            HttpURLConnection c = (HttpURLConnection) url.openConnection();
            c.setRequestMethod("GET");
            c.setDoOutput(true);
            c.connect();

            String PATH = "/mnt/sdcard/Download/";
            File file = new File(PATH);
            file.mkdirs();
            File outputFile = new File(file, "update.apk");
            if(outputFile.exists()){
                outputFile.delete();
            }
            FileOutputStream fos = new FileOutputStream(outputFile);

            InputStream is = c.getInputStream();

            byte[] buffer = new byte[1024];
            int len1 = 0;
            while ((len1 = is.read(buffer)) != -1) {
                fos.write(buffer, 0, len1);
            }
            fos.close();
            is.close();

            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.fromFile(new File("/mnt/sdcard/Download/update.apk")), "application/vnd.android.package-archive");
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // without this flag android returned a intent error!
            context.startActivity(intent);


        } catch (Exception e) {
            Log.e("UpdateAPP", "Update error! " + e.getMessage());
        }
        return null;
    }
}   

To use it, in your main activity call by this way:

atualizaApp = new UpdateApp();
atualizaApp.setContext(getApplicationContext());
atualizaApp.execute("http://serverurl/appfile.apk");

This was posted on the Hibernate forum a few years back when asked about why this worked in Hibernate 2 but not in Hibernate 3:

Limit was never a supported clause in HQL. You are meant to use setMaxResults().

So if it worked in Hibernate 2, it seems that was by coincidence, rather than by design. I think this was because the Hibernate 2 HQL parser would replace the bits of the query that it recognised as HQL, and leave the rest as it was, so you could sneak in some native SQL. Hibernate 3, however, has a proper AST HQL Parser, and it's a lot less forgiving.

I think Query.setMaxResults() really is your only option.

Here is a practical example of Anchor tag with different

The selected answer authored by Anurag is only partially correct. Due to some internals of jQuery's event handling, the proposed bindFirst function will not work if you have a mix of handlers with and without filters (ie: $(document).on("click", handler) vs $(document).on("click", "button", handler)).

The issue is that jQuery will place (and expect) that the first elements in the handler array will be these filtered handlers, so placing our event without a filter at the beginning breaks this logic and things start to fall apart. The updated bindFirst function should be as follows:

$.fn.bindFirst = function (name, fn) {
    // bind as you normally would
    // don't want to miss out on any jQuery magic
    this.on(name, fn);

    // Thanks to a comment by @Martin, adding support for
    // namespaced events too.
    this.each(function () {
        var handlers = $._data(this, 'events')[name.split('.')[0]];
        // take out the handler we just inserted from the end
        var handler = handlers.pop();
        // get the index of the first handler without a selector
        var firstNonDelegate = handlers.first(function(h) { return !h.selector; });
        var index = firstNonDelegate ? handlers.indexOf(firstNonDelegate)
                                     : handlers.length; // Either all handlers are selectors or we have no handlers
        // move it at the beginning
        handlers.splice(index, 0, handler);
    });
};

Besides the box-shadow, transform and border options mentioned in other answers, WebKit browsers currently also obey -webkit-text-fill-color to set the colour of the "time elapsed" numbers, but since there is no way to set their background (which might vary with platform, e.g. inverted high-contrast modes on some operating systems), you would be advised to set -webkit-text-fill-color to the value "initial" if you've used it elsewhere and the audio element is inheriting this, otherwise some users might find those numbers unreadable.

I was creating several buttons for each phone number in an array so each button needed a different phone number to call. I used the setTag function as I was creating several buttons within a for loop:

for (NSInteger i = 0; i < _phoneNumbers.count; i++) {

    UIButton *phoneButton = [[UIButton alloc] initWithFrame:someFrame];
    [phoneButton setTitle:_phoneNumbers[i] forState:UIControlStateNormal];

    [phoneButton setTag:i];

    [phoneButton addTarget:self
                    action:@selector(call:)
          forControlEvents:UIControlEventTouchUpInside];
}

Then in my call: method I used the same for loop and an if statement to pick the correct phone number:

- (void)call:(UIButton *)sender
{
    for (NSInteger i = 0; i < _phoneNumbers.count; i++) {
        if (sender.tag == i) {
            NSString *callString = [NSString stringWithFormat:@"telprompt://%@", _phoneNumbers[i]];
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callString]];
        }
    }
}

If you don't want to SELECT SLEEP(1);, you can also DO SLEEP(1); It's useful for those situations in procedures where you don't want to see output.

e.g.

SELECT ...
DO SLEEP(5);
SELECT ...

In my case I misspelled , I was referring as ngmodel istead of ngModel :) Hope It helps!

What you're doing is valid for the current session (limited to the terminal that you're working in). You need to persist those changes. Consider adding commands in steps 1-3 above to your ${HOME}/.bashrc.

Does that work in IE6?

No, IE6 does not support attribute selectors at all, cf. CSS Compatibility and Internet Explorer.

You might find How to workaround: IE6 does not support CSS “attribute” selectors worth the read.

EDIT
If you are to ignore IE6, you could do (CSS2.1):

input[type=submit][disabled=disabled],
button[disabled=disabled] {
    ...
}

CSS3 (IE9+):

input[type=submit]:disabled,
button:disabled {
    ...
}

You can substitute [disabled=disabled] (attribute value) with [disabled] (attribute presence).

You have to add a folder to the Sublime Text window in order to navigate via the sidebar. Go to File -> Open Folder... and select the highest directory you want to be able to navigate.

Also, 'View -> Sidebar -> Show Sidebar' if it still doesn't show. In the new version, there is only an 'open' menu and no separate option for opening a folder.

Use config.to_prepare to load you monkey patches/extensions for every request in development mode.

config.to_prepare do |action_dispatcher|
 # More importantly, will run upon every request in development, but only once (during boot-up) in production and test.
 Rails.logger.info "\n--- Loading extensions for #{self.class} "
 Dir.glob("#{Rails.root}/lib/extensions/**/*.rb").sort.each do |entry|
   Rails.logger.info "Loading extension(s): #{entry}"
   require_dependency "#{entry}"
 end
 Rails.logger.info "--- Loaded extensions for #{self.class}\n"

end

A is the key, max(date) is the value, we might simplify the query as below:

SELECT distinct A, max(date) over (partition by A)
  FROM TABLENAME

I simply use the ratio of the screen size, which works fine for me.

const { width, height } = Dimensions.get('window');

// Use iPhone6 as base size which is 375 x 667
const baseWidth = 375;
const baseHeight = 667;

const scaleWidth = width / baseWidth;
const scaleHeight = height / baseHeight;
const scale = Math.min(scaleWidth, scaleHeight);

export const scaledSize =
    (size) => Math.ceil((size * scale));

Test

const size = {
    small: scaledSize(25),
    oneThird: scaledSize(125),
    fullScreen: scaledSize(375),
};

console.log(size);

// iPhone 5s
{small: 22, oneThird: 107, fullScreen: 320}
// iPhone 6s
{small: 25, oneThird: 125, fullScreen: 375}
// iPhone 6s Plus
{small: 28, oneThird: 138, fullScreen: 414}

                                }];

Most of the solutions on this question all require you to specify the 'page' on both the li and the a (via HtmlHelper) tag. Both @Wolles and @Crush's answers eliminated this duplication, which was nice, but they were using HtmlHelper extension methods instead of TagHelpers. And I wanted to use a TagHelper and support Razor Pages.

You can read my full post here (and get the source code), but the gist of it is:

<bs-menu-link asp-page="/Events/Index" menu-text="Events"></bs-menu-link>

Would render (if the link was active obviously):

<li class="active"><a href="/Events">Events</a></li>

My TagHelper leverages the AnchorTagHelper internally (thus supporting asp-page, asp-controller, asp-action, etc. attributes). The 'checks' for active or not is similar to many of the answers to this post.

It sounds like you might need to create and query linked database servers in SQL Server

At the moment you've created a query that's going between different databases using a 3 part name mydatabase.dbo.mytable but you need to go up a level and use a 4 part name myserver.mydatabase.dbo.mytable, see this post on four part naming for more info

edit
The four part naming for your existing query would be as shown below (which I suspect you may have already tried?), but this assumes you can "get to" the remote database with the four part name, you might need to edit your host file / register the server or otherwise identify where to find database.windows.net.

INSERT INTO [DATABASE.WINDOWS.NET].[basecampdev].[dbo].[invoice]
       ([InvoiceNumber]
       ,[TotalAmount]
       ,[IsActive]
       ,[CreatedBy]
       ,[UpdatedBy]
       ,[CreatedDate]
       ,[UpdatedDate]
       ,[Remarks])
SELECT [InvoiceNumber]
       ,[TotalAmount]
       ,[IsActive]
       ,[CreatedBy]
       ,[UpdatedBy]
       ,[CreatedDate]
       ,[UpdatedDate]
       ,[Remarks] FROM [BC1-PC].[testdabse].[dbo].[invoice]

If you can't access the remote server then see if you can create a linked database server:

EXEC sp_addlinkedserver [database.windows.net];
GO
USE tempdb;
GO
CREATE SYNONYM MyInvoice FOR 
    [database.windows.net].basecampdev.dbo.invoice;
GO

Then you can just query against MyEmployee without needing the full four part name

I like to give explain here, with suitable example.

Consider a case here..

int totalValue = MySession.ListCustomerAccounts()
                          .FindAll(ac => ac.AccountHead.AccountHeadID 
                                         == accountHead.AccountHeadID)
                          .Sum(account => account.AccountValue);

Here Consider the functions I am using ..

1. ListCustomerAccounts() // User Defined
2. FindAll()              // Pre-defined Library Function

I can easily use ListCustomerAccount and FindAll instead of.,

int totalValue = 0; 
List<CustomerAccounts> custAccounts = ListCustomerAccounts();
if(custAccounts !=null ){
  List<CustomerAccounts> custAccountsFiltered = 
        custAccounts.FindAll(ac => ac.AccountHead.AccountHeadID 
                                   == accountHead.AccountHeadID );
   if(custAccountsFiltered != null)
      totalValue = custAccountsFiltered.Sum(account => 
                                            account.AccountValue).ToString();
}

NOTE : Since AccountValue is not null, the Sum() function will not return null., Hence I can use it directly.

Find timestamp from DateTime:

private long ConvertToTimestamp(DateTime value)
{
    TimeZoneInfo NYTimeZone = TimeZoneInfo.FindSystemTimeZoneById("Eastern Standard Time");
    DateTime NyTime = TimeZoneInfo.ConvertTime(value, NYTimeZone);
    TimeZone localZone = TimeZone.CurrentTimeZone;
    System.Globalization.DaylightTime dst = localZone.GetDaylightChanges(NyTime.Year);
    NyTime = NyTime.AddHours(-1);
    DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0).ToLocalTime();
    TimeSpan span = (NyTime - epoch);
    return (long)Convert.ToDouble(span.TotalSeconds);
}

Building on Habib's answer, you could write an extension method:

public static bool ValidateJSON(this string s)
{
    try
    {
        JToken.Parse(s);
        return true;
    }
    catch (JsonReaderException ex)
    {
        Trace.WriteLine(ex);
        return false;
    }
}

Which can then be used like this:

if(stringObject.ValidateJSON())
{
    // Valid JSON!
}

use @Transient to make JPA ignoring the field.

but! Jackson will not serialize that field as well. to solve just add @JsonProperty

an example

@Transient
@JsonProperty
private boolean locked;

Sub Results2()

    Dim rCell As Range
    Dim shSource As Worksheet
    Dim shDest As Worksheet
    Dim lCnt As Long

    Set shSource = ThisWorkbook.Sheets("Sheet1")
    Set shDest = ThisWorkbook.Sheets("Sheet2")

    For Each rCell In shSource.Range("A1", shSource.Cells(shSource.Rows.Count, 1).End(xlUp)).Cells
        lCnt = lCnt + 1
        shDest.Range("A4").Offset(0, lCnt * 4).Formula = "=" & rCell.Address(False, False, , True) & "+" & rCell.Offset(0, 1).Address(False, False, , True)
    Next rCell

End Sub

This loops through column A of sheet1 and creates a formula in sheet2 for every cell. To find the last cell in Sheet1, I start at the bottom (shSource.Rows.Count) and .End(xlUp) to get the last cell in the column that's not blank.

To create the elements of the formula, I use the Address property of the cell on Sheet. I'm using three of the arguments to Address. The first two are RowAbsolute and ColumnAbsolute, both set to false. I don't care about the third argument, but I set the fourth argument (External) to True so that it includes the sheet name.

I prefer to go from Source to Destination rather than the other way. But that's just a personal preference. If you want to work from the destination,

Sub Results3()

    Dim i As Long, lCnt As Long
    Dim sh As Worksheet

    lCnt = Application.WorksheetFunction.CountA(ThisWorkbook.Sheets("Sheet1").Columns(1))
    Set sh = ThisWorkbook.Sheets("Sheet2")

    Const sSOURCE As String = "Sheet1!"

    For i = 1 To lCnt
        sh.Range("A1").Offset(0, 4 * (i - 1)).Formula = "=" & sSOURCE & "A" & i & " + " & sSOURCE & "B" & i
    Next i

End Sub

Oddly enough it was an Intel thing not a Microsoft thing. X86 referred to the Intel CPU series from the 8086 to the 80486. The Pentium series still use the same addressing system. The x64 refers to the I64 addressing system that Intel came out with later for the 64-bit CPUs. So Windows was just following Intel's architecture naming.

You need to do two things:

• Start the thread
• Wait for the thread to finish (die) before proceeding

ie

one.start();
one.join();

If you don't start() it, nothing will happen - creating a Thread doesn't execute it.

If you don't join) it, your main thread may finish and exit and the whole program exit before the other thread has been scheduled to execute. It's indeterminate whether it runs or not if you don't join it. The new thread may usually run, but may sometimes not run. Better to be certain.

A[A==NDV]=numpy.nan

A==NDV will produce a boolean array that can be used as an index for A

If you can use a Database project in Visual Studio, you can make your changes in the project and use schema compare to synchronize the changes to your database.

This way, dropping and recreating the dependent objects is handled by the change script.

A simple approach is to set a view theme as outlined here.

some_view.xml

<ImageView
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:background="?attr/selectableItemBackgroundBorderless"
   android:focusable="true"
   android:src="@drawable/up_arrow"
   android:theme="@style/SomeButtonTheme"/>

some_style.xml

<style name="SomeButtonTheme" >
   <item name="colorControlHighlight">@color/someColor</item>
</style>

@Ahmed Elmahy following approach should help you out, when you have got a vector of column names you want to remove from your dataframe:

test_df <- data.frame(col1 = c("a", "b", "c", "d", "e"), col2 = seq(1, 5), col3 = rep(3, 5))
rm_col <- c("col2")
test_df[, !(colnames(test_df) %in% rm_col), drop = FALSE]

All the best, ExploreR

You can iterate the key/value pairs of the saveData object to build an array of the pairs, then use join("&") on the resulting array:

var a = [];
for (key in saveData) {
    a.push(key+"="+saveData[key]);
}
var serialized = a.join("&") // a=2&c=1

In matplotlib grey colors can be given as a string of a numerical value between 0-1.
For example c = '0.1'

Then you can convert your third variable in a value inside this range and to use it to color your points.
In the following example I used the y position of the point as the value that determines the color:

from matplotlib import pyplot as plt

x = [1, 2, 3, 4, 5, 6, 7, 8, 9]
y = [125, 32, 54, 253, 67, 87, 233, 56, 67]

color = [str(item/255.) for item in y]

plt.scatter(x, y, s=500, c=color)

plt.show()

Teylyn's answer worked great for me, but I had to modify it a bit to get proper results. I want to provide an extended explanation for whoever would need it.

My setup was as follows:

• Sheet1: full data of 2014
• Sheet2: updated rows for 2015 in A1:D50, sorted by first column
• Sheet3: merged rows
• My data does not have a header row

I put the following formula in cell A1 of Sheet3:

=iferror(vlookup(Sheet1!A$1;Sheet2!$A$1:$D$50;column(A1);false);Sheet1!A1)

Read this as follows: Take the value of the first column in Sheet1 (old data). Look up in Sheet2 (updated rows). If present, output the value from the indicated column in Sheet2. On error, output the value for the current column of Sheet1.

Notes:

• In my version of the formula, ";" is used as parameter separator instead of ",". That is because I am located in Europe and we use the "," as decimal separator. Change ";" back to "," if you live in a country where "." is the decimal separator.

• A$1: means always take column 1 when copying the formula to a cell in a different column. $A$1 means: always take the exact cell A1, even when copying the formula to a different row or column.

After pasting the formula in A1, I extended the range to columns B, C, etc., until the full width of my table was reached. Because of the $-signs used, this gives the following formula's in cells B1, C1, etc.:

=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(B1);FALSE);'Sheet1'!B1)
=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(C1);FALSE);'Sheet1'!C1)

and so forth. Note that the lookup is still done in the first column. This is because VLOOKUP needs the lookup data to be sorted on the column where the lookup is done. The output column is however the column where the formula is pasted.

Next, select a rectangle in Sheet 3 starting at A1 and having the size of the data in Sheet1 (same number of rows and columns). Press Ctrl-D to copy the formulas of the first row to all selected cells.

Cells A2, A3, etc. will get these formulas:

=IFERROR(VLOOKUP('Sheet1'!$A2;'Sheet2'!$A$1:$D$50;COLUMN(A2);FALSE);'Sheet1'!A2)
=IFERROR(VLOOKUP('Sheet1'!$A3;'Sheet2'!$A$1:$D$50;COLUMN(A3);FALSE);'Sheet1'!A3)

Because of the use of $-signs, the lookup area is constant, but input data is used from the current row.

Using Guava, it gets syntactically simplified:

Stats.meanOf(numericList);

NPM was returning the old version after running $ sudo npm install npm -g.

Restarting the terminal (i.e. close and open again) fixed the issue for me and $ npm --version began returning the expected version.

_{* @Rimian mentions the need to reload the terminal in a comment of another answer.}

You could do this:

SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%MyColumn%'
ORDER BY schema_name, table_name;

Reference:

• SQL SERVER – Query to Find Column From All Tables of Database

You need to use HAVING, not WHERE.

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

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

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

UPDATE: I have created a video on sending multipart/form-data requests to explain this better.

Actually, Postman can do this. Here is a screenshot

Newer version : Screenshot captured from postman chrome extension

Make sure you check the comment from @maxkoryukov

Be careful with explicit Content-Type header. Better - do not set it's value, the Postman is smart enough to fill this header for you. BUT, if you want to set the Content-Type: multipart/form-data - do not forget about boundary field.

$result = array_filter($arr, function ($var) {   
  $found = false;
  array_walk_recursive($var, function ($item, $key) use (&$found) {  
    $found = $found || $key == "name" && $item == "cat 1";
  });
  return $found;
});

I've made a single powerfull script that will:

-Compile and run multi language code like C, C++, Java, Python and C#.
-Delete the old executable before compiling code.
-Only run the code if it's compiled successfully.

I've also made a very noob friendly tutorial Transform Notepad++ to Powerful Multi Languages IDE which contains some additional scripts like to only run or Compile the code, run code inside CMD etc.

You can use CSS3 transitions or maybe CSS3 animations to slide in an element.

For browser support: http://caniuse.com/

I made two quick examples just to show you how I mean.

CSS transition (on hover)

Demo One

Relevant Code

.wrapper:hover #slide {
    transition: 1s;
    left: 0;
}

In this case, Im just transitioning the position from left: -100px; to 0; with a 1s. duration. It's also possible to move the element using transform: translate();

CSS animation

Demo Two

#slide {
    position: absolute;
    left: -100px;
    width: 100px;
    height: 100px;
    background: blue;
    -webkit-animation: slide 0.5s forwards;
    -webkit-animation-delay: 2s;
    animation: slide 0.5s forwards;
    animation-delay: 2s;
}

@-webkit-keyframes slide {
    100% { left: 0; }
}

@keyframes slide {
    100% { left: 0; }
}

Same principle as above (Demo One), but the animation starts automatically after 2s, and in this case I've set animation-fill-mode to forwards, which will persist the end state, keeping the div visible when the animation ends.

Like I said, two quick example to show you how it could be done.

EDIT: For details regarding CSS Animations and Transitions see:

Hope this helped.

Read Google-gson

Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object.

Add the following line to your MODULE LEVEL build.gradle configuration:

dependencies {
     implementation 'com.google.code.gson:gson:2.8.5' // Old 2.8.2
}

R has many *apply functions which are ably described in the help files (e.g. ?apply). There are enough of them, though, that beginning useRs may have difficulty deciding which one is appropriate for their situation or even remembering them all. They may have a general sense that "I should be using an *apply function here", but it can be tough to keep them all straight at first.

Despite the fact (noted in other answers) that much of the functionality of the *apply family is covered by the extremely popular plyr package, the base functions remain useful and worth knowing.

This answer is intended to act as a sort of signpost for new useRs to help direct them to the correct *apply function for their particular problem. Note, this is not intended to simply regurgitate or replace the R documentation! The hope is that this answer helps you to decide which *apply function suits your situation and then it is up to you to research it further. With one exception, performance differences will not be addressed.

• apply - When you want to apply a function to the rows or columns of a matrix (and higher-dimensional analogues); not generally advisable for data frames as it will coerce to a matrix first.

  # Two dimensional matrix
  M <- matrix(seq(1,16), 4, 4)
  
  # apply min to rows
  apply(M, 1, min)
  [1] 1 2 3 4
  
  # apply max to columns
  apply(M, 2, max)
  [1]  4  8 12 16
  
  # 3 dimensional array
  M <- array( seq(32), dim = c(4,4,2))
  
  # Apply sum across each M[*, , ] - i.e Sum across 2nd and 3rd dimension
  apply(M, 1, sum)
  # Result is one-dimensional
  [1] 120 128 136 144
  
  # Apply sum across each M[*, *, ] - i.e Sum across 3rd dimension
  apply(M, c(1,2), sum)
  # Result is two-dimensional
       [,1] [,2] [,3] [,4]
  [1,]   18   26   34   42
  [2,]   20   28   36   44
  [3,]   22   30   38   46
  [4,]   24   32   40   48
  

  If you want row/column means or sums for a 2D matrix, be sure to investigate the highly optimized, lightning-quick colMeans, rowMeans, colSums, rowSums.

• lapply - When you want to apply a function to each element of a list in turn and get a list back.

  This is the workhorse of many of the other *apply functions. Peel back their code and you will often find lapply underneath.

  x <- list(a = 1, b = 1:3, c = 10:100) 
  lapply(x, FUN = length) 
  $a 
  [1] 1
  $b 
  [1] 3
  $c 
  [1] 91
  lapply(x, FUN = sum) 
  $a 
  [1] 1
  $b 
  [1] 6
  $c 
  [1] 5005
  

• sapply - When you want to apply a function to each element of a list in turn, but you want a vector back, rather than a list.

  If you find yourself typing unlist(lapply(...)), stop and consider sapply.

  x <- list(a = 1, b = 1:3, c = 10:100)
  # Compare with above; a named vector, not a list 
  sapply(x, FUN = length)  
  a  b  c   
  1  3 91
  
  sapply(x, FUN = sum)   
  a    b    c    
  1    6 5005 
  

  In more advanced uses of sapply it will attempt to coerce the result to a multi-dimensional array, if appropriate. For example, if our function returns vectors of the same length, sapply will use them as columns of a matrix:

  sapply(1:5,function(x) rnorm(3,x))
  

  If our function returns a 2 dimensional matrix, sapply will do essentially the same thing, treating each returned matrix as a single long vector:

  sapply(1:5,function(x) matrix(x,2,2))
  

  Unless we specify simplify = "array", in which case it will use the individual matrices to build a multi-dimensional array:

  sapply(1:5,function(x) matrix(x,2,2), simplify = "array")
  

  Each of these behaviors is of course contingent on our function returning vectors or matrices of the same length or dimension.

• vapply - When you want to use sapply but perhaps need to squeeze some more speed out of your code.

  For vapply, you basically give R an example of what sort of thing your function will return, which can save some time coercing returned values to fit in a single atomic vector.

  x <- list(a = 1, b = 1:3, c = 10:100)
  #Note that since the advantage here is mainly speed, this
  # example is only for illustration. We're telling R that
  # everything returned by length() should be an integer of 
  # length 1. 
  vapply(x, FUN = length, FUN.VALUE = 0L) 
  a  b  c  
  1  3 91
  

• mapply - For when you have several data structures (e.g. vectors, lists) and you want to apply a function to the 1st elements of each, and then the 2nd elements of each, etc., coercing the result to a vector/array as in sapply.

  This is multivariate in the sense that your function must accept multiple arguments.

  #Sums the 1st elements, the 2nd elements, etc. 
  mapply(sum, 1:5, 1:5, 1:5) 
  [1]  3  6  9 12 15
  #To do rep(1,4), rep(2,3), etc.
  mapply(rep, 1:4, 4:1)   
  [[1]]
  [1] 1 1 1 1
  
  [[2]]
  [1] 2 2 2
  
  [[3]]
  [1] 3 3
  
  [[4]]
  [1] 4
  

• Map - A wrapper to mapply with SIMPLIFY = FALSE, so it is guaranteed to return a list.

  Map(sum, 1:5, 1:5, 1:5)
  [[1]]
  [1] 3
  
  [[2]]
  [1] 6
  
  [[3]]
  [1] 9
  
  [[4]]
  [1] 12
  
  [[5]]
  [1] 15
  

• rapply - For when you want to apply a function to each element of a nested list structure, recursively.

  To give you some idea of how uncommon rapply is, I forgot about it when first posting this answer! Obviously, I'm sure many people use it, but YMMV. rapply is best illustrated with a user-defined function to apply:

  # Append ! to string, otherwise increment
  myFun <- function(x){
      if(is.character(x)){
        return(paste(x,"!",sep=""))
      }
      else{
        return(x + 1)
      }
  }
  
  #A nested list structure
  l <- list(a = list(a1 = "Boo", b1 = 2, c1 = "Eeek"), 
            b = 3, c = "Yikes", 
            d = list(a2 = 1, b2 = list(a3 = "Hey", b3 = 5)))
  
  
  # Result is named vector, coerced to character          
  rapply(l, myFun)
  
  # Result is a nested list like l, with values altered
  rapply(l, myFun, how="replace")
  

• tapply - For when you want to apply a function to subsets of a vector and the subsets are defined by some other vector, usually a factor.

  The black sheep of the *apply family, of sorts. The help file's use of the phrase "ragged array" can be a bit confusing, but it is actually quite simple.

  A vector:

  x <- 1:20
  

  A factor (of the same length!) defining groups:

  y <- factor(rep(letters[1:5], each = 4))
  

  Add up the values in x within each subgroup defined by y:

  tapply(x, y, sum)  
   a  b  c  d  e  
  10 26 42 58 74 
  

  More complex examples can be handled where the subgroups are defined by the unique combinations of a list of several factors. tapply is similar in spirit to the split-apply-combine functions that are common in R (aggregate, by, ave, ddply, etc.) Hence its black sheep status.

What about simple regular expression?

url = "http://www.example.com/path/to/somwhere";
urlParts = /^(?:\w+\:\/\/)?([^\/]+)(.*)$/.exec(url);
hostname = urlParts[1]; // www.example.com
path = urlParts[2]; // /path/to/somwhere

Try a \<Space> before 12, like so:

:set guifont=Monospace\ 12

no, but it runs fine on win64, and can create win64 .EXEs

You can use the isNaN function to determine if a value does not convert to a number. Example as below:

function checkInp()
{
  var x=document.forms["myForm"]["age"].value;
  if (isNaN(x)) 
  {
    alert("Must input numbers");
    return false;
  }
}

You could use a nested query:

Select
  ColumnA,
  ColumnB,
  calccolumn1,
  calccolumn1 / ColumnC as calccolumn2
From (
  Select
    ColumnA,
    ColumnB,
    ColumnC,
    ColumnA + ColumnB As calccolumn1
  from t42
);

With a row with values 3, 4, 5 that gives:

   COLUMNA    COLUMNB CALCCOLUMN1 CALCCOLUMN2
---------- ---------- ----------- -----------
         3          4           7         1.4

You can also just repeat the first calculation, unless it's really doing something expensive (via a function call, say):

Select
  ColumnA,
  ColumnB,
  ColumnA + ColumnB As calccolumn1,
  (ColumnA + ColumnB) / ColumnC As calccolumn2
from t42; 

   COLUMNA    COLUMNB CALCCOLUMN1 CALCCOLUMN2
---------- ---------- ----------- -----------
         3          4           7         1.4 

You can use the strip() to remove trailing and leading spaces.

>>> s = '   abd cde   '
>>> s.strip()
'abd cde'

Note: the internal spaces are preserved

If this is a simple Java project, You essentially create a new project and give the location of the existing code. The project wizard will tell you that it will use existing sources.

Also, Eclipse 3.3.2 is ancient history, you guys should really upgrade. This is like using Visual Studio 5.

If relative paths are what you want you can just use the -Name flag.

Get-ChildItem "C:\windows\System32" -Recurse -Filter *.txt -Name

I had the same issue it was due to that I had the bootstrap class "hidden-lg" on the table which caused it to stupidly become display: block !important;

I wonder how Bootstrap never considered to just instead do this:

@media (min-width: 1200px) {
    .hidden-lg {
         display: none;
    }
}

And then just leave the element whatever display it had before for other screensizes.. Perhaps it is too advanced for them to figure out..

Anyway so:

table {
    display: table; /* check so these really applies */
    width: 100%;
}

should work

As an alternative, in ES6, spread syntax might be used. ${Object.keys(alerts).length + 1} returns next id for alert.

let alerts = { _x000D_
    1: {app:'helloworld',message:'message'},_x000D_
    2: {app:'helloagain',message:'another message'}_x000D_
};_x000D_
_x000D_
alerts = {_x000D_
  ...alerts, _x000D_
  [`${Object.keys(alerts).length + 1}`]: _x000D_
  { _x000D_
    app: `helloagain${Object.keys(alerts).length + 1}`,message: 'next message' _x000D_
  } _x000D_
};_x000D_
_x000D_
console.log(alerts);

My team ran into this problem when using Node with React Native and PouchDB. Here is how we solved it...

NPM install buffer:

$ npm install --save buffer

Ensure Buffer, btoa, and atob are loaded as a globals:

global.Buffer = global.Buffer || require('buffer').Buffer;

if (typeof btoa === 'undefined') {
  global.btoa = function (str) {
    return new Buffer(str, 'binary').toString('base64');
  };
}

if (typeof atob === 'undefined') {
  global.atob = function (b64Encoded) {
    return new Buffer(b64Encoded, 'base64').toString('binary');
  };
}

As of R 3.3.0, one may use startsWith() as a faster alternative to grepl():

which(startsWith(mydata_2$height_seca1, 1578))

the Object.prototype.toString is a good way, but its performance is the worst.

http://jsperf.com/check-js-type

Use typeof to solve some basic problem(String, Number, Boolean...) and use Object.prototype.toString to solve something complex(like Array, Date, RegExp).

and this is my solution:

var type = (function(global) {
    var cache = {};
    return function(obj) {
        var key;
        return obj === null ? 'null' // null
            : obj === global ? 'global' // window in browser or global in nodejs
            : (key = typeof obj) !== 'object' ? key // basic: string, boolean, number, undefined, function
            : obj.nodeType ? 'object' // DOM element
            : cache[key = ({}).toString.call(obj)] // cached. date, regexp, error, object, array, math
            || (cache[key] = key.slice(8, -1).toLowerCase()); // get XXXX from [object XXXX], and cache it
    };
}(this));

use as:

type(function(){}); // -> "function"
type([1, 2, 3]); // -> "array"
type(new Date()); // -> "date"
type({}); // -> "object"

This error can get thrown if your data frame has sf geometry columns.

try this one

return Content("<form action='actionname' id='frmTest' method='post'><input type='hidden' name='someValue' value='" + someValue + "' /><input type='hidden' name='anotherValue' value='" + anotherValue + "' /></form><script>document.getElementById('frmTest').submit();</script>");

In your AsyncTask add one ProgressDialog like:

private final ProgressDialog dialog = new ProgressDialog(YourActivity.this);

you can setMessage in onPreExecute() method like:

this.dialog.setMessage("Processing..."); 
this.dialog.show();

and in your onPostExecute(Void result) method dismiss your ProgressDialog.

For me the answer was:

1) Get the Repos from

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
sudo rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm

2) Install it via:

sudo yum update
sudo yum install php-mcrypt*

3) Edit the mcrypt.ini

sudo nano /etc/php.d/mcrypt.ini

add this

extension=/usr/lib64/php/modules/mcrypt.so

Finally 4) Restart your webserver:

sudo service httpd restart

I run this steps in CentOS 6.3 (64) on Azure From Microsoft Linux image

Hope it helps you.

Best Regards.

To get the checked state of your checkbox the path would be:

this.refs.complete.state.checked

The alternative is to get it from the event passed into the handleChange method:

event.target.checked

You should also be able to accomplish a similar thing using the premain method of a Java agent.

The manifest of the agent JAR file must contain the attribute Premain-Class. The value of this attribute is the name of the agent class. The agent class must implement a public static premain method similar in principle to the main application entry point. After the Java Virtual Machine (JVM) has initialized, each premain method will be called in the order the agents were specified, then the real application main method will be called. Each premain method must return in order for the startup sequence to proceed.

The standard mocking frameworks are creating proxy classes. This is the reason why they are technically limited to interfaces and virtual methods.

If you want to mock 'normal' methods as well, you need a tool that works with instrumentation instead of proxy generation. E.g. MS Moles and Typemock can do that. But the former has a horrible 'API', and the latter is commercial.

Getting Different Types of Extra from Intent

To access data from Intent you should know two things.

• KEY
• DataType of your data.

There are different methods in Intent class to extract different kind of data types. It looks like this

getIntent().XXXX(KEY) or intent.XXX(KEY);

So if you know the datatype of your varibale which you set in otherActivity you can use the respective method.

Example to retrieve String in your Activity from Intent

String profileName = getIntent().getStringExtra("SomeKey");

List of different variants of methods for different dataType

You can see the list of available methods in Official Documentation of Intent.

The fastest way that I've found is:

// Open the file
$fp = @fopen($filename, 'r'); 

// Add each line to an array
if ($fp) {
   $array = explode("\n", fread($fp, filesize($filename)));
}

where $filename is going to be the path & name of your file, eg. ../filename.txt.

Depending how you've set up your text file, you'll have might have to play around with the \n bit.

From the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.

When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of ~/.bashrc.

Thus, if you want to get the same behavior for both login shells and interactive non-login shells, you should put all of your commands in either .bashrc or .bash_profile, and then have the other file source the first one.

<select>
    <option value="" disabled="disabled" selected="selected">Please select name</option>
  <option value="Tom">Tom</option>
  <option value="Marry">Marry</option>
  <option value="Jane">Jane</option>
  <option value="Harry">Harry</option>
</select>

I'm late to the party, but this is (unbelievably) still a problem as of the 11.05.2017. Here is a simple solution which will also work cross-platform with linear gradients:

You can use NullableValueTypes (like int?) for this. The code would be like this:

private void Example(int? arg1, int? arg2)
{
    if(!arg1.HasValue)
    {
        //do something
    }
    if(!arg2.HasValue)
    {
        //do something else
    }
}

You should use the ISO-8601 format for string representations of dates - anything else is dependent on the SQL Server language and dateformat settings.

The ISO-8601 format for a DATETIME when using only the date is: YYYYMMDD (no dashes or antyhing!)

For a DATETIME with the time portion, it's YYYY-MM-DDTHH:MM:SS (with dashes, and a T in the middle to separate date and time portions).

If you want to convert a string to a DATE for SQL Server 2008 or newer, you can use YYYY-MM-DD (with the dashes) to achieve the same result. And don't ask me why this is so inconsistent and confusing - it just is, and you'll have to work with that for now.

So in your case, you should try:

declare @a datetime
declare @b datetime 

set @a = '2012-04-06T12:23:45'   -- 6th of April, 2012
set @b = '2012-08-06T21:10:12'   -- 6th of August, 2012

exec LogProcedure 'AccountLog', N'test', @a, @b

Furthermore - your stored proc has problem, since you're concatenating together datetime and string into a string, but you're not converting the datetime to string first, and also, you're forgetting the close quotes in your statement after both dates.

So change this line here to this:

IF @DateFirst <> '' and @DateLast <> ''
   SET @FinalSQL  = @FinalSQL + '  OR CONVERT(Date, DateLog) >= ''' + 
                    CONVERT(VARCHAR(50), @DateFirst, 126) +   -- convert @DateFirst to string for concatenation!
                    ''' AND CONVERT(Date, DateLog) <=''' +  -- you need closing quotes after @DateFirst!
                    CONVERT(VARCHAR(50), @DateLast, 126) + ''''      -- convert @DateLast to string and also: closing tags after that missing!

With these settings, and once you've fixed your stored procedure which contains problems right now, it will work.

Python string parsing walkthrough

Split a string on space, get a list, show its type, print it out:

el@apollo:~/foo$ python
>>> mystring = "What does the fox say?"

>>> mylist = mystring.split(" ")

>>> print type(mylist)
<type 'list'>

>>> print mylist
['What', 'does', 'the', 'fox', 'say?']

If you have two delimiters next to each other, empty string is assumed:

el@apollo:~/foo$ python
>>> mystring = "its  so   fluffy   im gonna    DIE!!!"

>>> print mystring.split(" ")
['its', '', 'so', '', '', 'fluffy', '', '', 'im', 'gonna', '', '', '', 'DIE!!!']

Split a string on underscore and grab the 5th item in the list:

el@apollo:~/foo$ python
>>> mystring = "Time_to_fire_up_Kowalski's_Nuclear_reactor."

>>> mystring.split("_")[4]
"Kowalski's"

Collapse multiple spaces into one

el@apollo:~/foo$ python
>>> mystring = 'collapse    these       spaces'

>>> mycollapsedstring = ' '.join(mystring.split())

>>> print mycollapsedstring.split(' ')
['collapse', 'these', 'spaces']

When you pass no parameter to Python's split method, the documentation states: "runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace".

Hold onto your hats boys, parse on a regular expression:

el@apollo:~/foo$ python
>>> mystring = 'zzzzzzabczzzzzzdefzzzzzzzzzghizzzzzzzzzzzz'
>>> import re
>>> mylist = re.split("[a-m]+", mystring)
>>> print mylist
['zzzzzz', 'zzzzzz', 'zzzzzzzzz', 'zzzzzzzzzzzz']

The regular expression "[a-m]+" means the lowercase letters a through m that occur one or more times are matched as a delimiter. re is a library to be imported.

Or if you want to chomp the items one at a time:

el@apollo:~/foo$ python
>>> mystring = "theres coffee in that nebula"

>>> mytuple = mystring.partition(" ")

>>> print type(mytuple)
<type 'tuple'>

>>> print mytuple
('theres', ' ', 'coffee in that nebula')

>>> print mytuple[0]
theres

>>> print mytuple[2]
coffee in that nebula

int StringToWString(std::wstring &ws, const std::string &s)
{
    std::wstring wsTmp(s.begin(), s.end());

    ws = wsTmp;

    return 0;
}

I see that if you paste csv delimited text in Excel and do a "Text to Columns", it asks you for a "text qualifier". It's defaulted to a double quote so that it treats text within double quotes as literal. I imagine that Excel implements this by going one character at a time, if it encounters a "text qualifier", it keeps going to the next "qualifier". You can probably implement this yourself with a for loop and a boolean to denote if you're inside literal text.

public string[] CsvParser(string csvText)
{
    List<string> tokens = new List<string>();

    int last = -1;
    int current = 0;
    bool inText = false;

    while(current < csvText.Length)
    {
        switch(csvText[current])
        {
            case '"':
                inText = !inText; break;
            case ',':
                if (!inText) 
                {
                    tokens.Add(csvText.Substring(last + 1, (current - last)).Trim(' ', ',')); 
                    last = current;
                }
                break;
            default:
                break;
        }
        current++;
    }

    if (last != csvText.Length - 1) 
    {
        tokens.Add(csvText.Substring(last+1).Trim());
    }

    return tokens.ToArray();
}

find /path/to/  \( -iname '*.gif' -o -iname '*.jpg' \) -print0

will work. There might be a more elegant way.

So there are several ways to get a resource from a jar and each has slightly different syntax where the path needs to be specified differently.

The best explanation I have seen is this article from InfoWorld. I'll summarize here, but if you want to know more you should check out the article.

Methods

1. ClassLoader.getResourceAsStream().

Format: "/"-separated names; no leading "/" (all names are absolute).

Example: this.getClass().getClassLoader().getResourceAsStream("some/pkg/resource.properties");

2. Class.getResourceAsStream()

Format: "/"-separated names; leading "/" indicates absolute names; all other names are relative to the class's package

Example: this.getClass().getResourceAsStream("/some/pkg/resource.properties");

Updated Sep 2020: Changed article link. Original article was from Javaworld, it is now hosted on InfoWorld (and has many more ads)

An int array without elements is not necessarily null. It will only be null if it hasn't been allocated yet. See this tutorial for more information about Java arrays.

You can test the array's length:

void foo(int[] data)
{
  if(data.length == 0)
    return;
}

The debug module could really use some love, but at the moment the best you can do is use this:

- hosts: all
  gather_facts: no
  tasks:
    - shell: ps -eo pcpu,user,args | sort -r -k1 | head -n5
      register: ps

    - debug: var=ps.stdout_lines

It gives an output like this:

ok: [host1] => {
    "ps.stdout_lines": [
        "%CPU USER     COMMAND",
        " 1.0 root     /usr/bin/python",
        " 0.6 root     sshd: root@notty ",
        " 0.2 root     java",
        " 0.0 root     sort -r -k1"
    ]
}
ok: [host2] => {
    "ps.stdout_lines": [
        "%CPU USER     COMMAND",
        " 4.0 root     /usr/bin/python",
        " 0.6 root     sshd: root@notty ",
        " 0.1 root     java",
        " 0.0 root     sort -r -k1"
    ]
}

Just an update, Feb 1, 2019: cmd+shift+n on Mac now opens a new window where you can drag over tabs. I didn't find that out until I when through KyleMit's response and saw his key mapping suggestion was already mapped to the correct action.

Arrays are not very dynamic in VBScript. You'll have to use the ReDim Preserve statement to grow the existing array so it can accommodate an extra item:

ReDim Preserve yourArray(UBound(yourArray) + 1)
yourArray(UBound(yourArray)) = "Watermelons"

If you have a numpy array you can do this:

import numpy as np
from matplotlib import pyplot as plt

data = np.array([
    [1, 2],
    [2, 3],
    [3, 6],
])
x, y = data.T
plt.scatter(x,y)
plt.show()

use window.localStorage... like this

var refresh = $window.localStorage.getItem('refresh');
console.log(refresh);
if (refresh===null){
    window.location.reload();
    $window.localStorage.setItem('refresh', "1");
}

It's work for me

If you want do many calculation with 2d array, you should use NumPy array instead of nest list.

for your question, you can use:zip(*a) to transpose it:

In [55]: a=[[1,1],[2,1],[3,1]]
In [56]: zip(*a)
Out[56]: [(1, 2, 3), (1, 1, 1)]
In [57]: zip(*a)[0]
Out[57]: (1, 2, 3)

Try Winhttrack

...offline browser utility.

It allows you to download a World Wide Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer. HTTrack arranges the original site's relative link-structure. Simply open a page of the "mirrored" website in your browser, and you can browse the site from link to link, as if you were viewing it online. HTTrack can also update an existing mirrored site, and resume interrupted downloads. HTTrack is fully configurable, and has an integrated help system.

WinHTTrack is the Windows 2000/XP/Vista/Seven release of HTTrack, and WebHTTrack the Linux/Unix/BSD release...

If you don't need typesafe, just bring block to a new separated file and change the extension to .js,.jsx

How about this?

>>> tuple_list = [("pineapple", 5), ("cherry", 7), ("kumquat", 3), ("plum", 11)]
>>> [x for x, y in enumerate(tuple_list) if y[1] == 7]
[1]
>>> [x for x, y in enumerate(tuple_list) if y[0] == 'kumquat']
[2]

As pointed out in the comments, this would get all matches. To just get the first one, you can do:

>>> [y[0] for y in tuple_list].index('kumquat')
2

There is a good discussion in the comments as to the speed difference between all the solutions posted. I may be a little biased but I would personally stick to a one-liner as the speed we're talking about is pretty insignificant versus creating functions and importing modules for this problem, but if you are planning on doing this to a very large amount of elements you might want to look at the other answers provided, as they are faster than what I provided.

x.length-4 only accounts for extensions of 3 characters. What if you have filename.jpegor filename.pl?

EDIT:

To answer... sure, if you always have an extension of .jpg, x.length-4 would work just fine.

However, if you don't know the length of your extension, any of a number of solutions are better/more robust.

x = x.replace(/\..+$/, '');

OR

x = x.substring(0, x.lastIndexOf('.'));

OR

x = x.replace(/(.*)\.(.*?)$/, "$1");

OR (with the assumption filename only has one dot)

parts = x.match(/[^\.]+/);
x = parts[0];

OR (also with only one dot)

parts = x.split(".");
x = parts[0];

Adding custom rules is useful if you create a jQuery widget that requires custom CSS (such as extending the existing jQueryUI CSS framework for your particular widget). This solution builds on Taras's answer (the first one above).

Assuming your HTML markup has a button with an id of "addrule" and a div with an id of "target" containing some text:

jQuery code:

$( "#addrule" ).click(function () { addcssrule($("#target")); });

function addcssrule(target) 
{ 
var cssrules =  $("<style type='text/css'> </style>").appendTo("head");

cssrules.append(".redbold{ color:#f00; font-weight:bold;}"); 
cssrules.append(".newfont {font-family: arial;}"); 
target.addClass("redbold newfont");     
}       

The advantage of this approach is that you can reuse variable cssrules in your code to add or subtract rules at will. If cssrules is embedded in a persistent object such as a jQuery widget you have a persistent local variable to work with.

Update: use Darin's / John Resig answer, just keep in mind that you dont need to specifiy thisArg for min, so Math.min.apply(null, arr) will work just fine.

or you can just sort the array and get value #1: [2,6,7,4,1].sort()[0]

[!] But without supplying custom number sorting function, this will only work in one, very limited case: positive numbers less than 10. See how it would break:

var a = ['', -0.1, -2, -Infinity, Infinity, 0, 0.01, 2, 2.0, 2.01, 11, 1, 1e-10, NaN];

// correct: 
a.sort( function (a,b) { return a === b ? 0 : a < b ? -1: 1} );
//Array [NaN, -Infinity, -2, -0.1, 0, "", 1e-10, 0.01, 1, 2, 2, 2.01, 11, Infinity]

// incorrect:
a.sort();
//Array ["", -0.1, -2, -Infinity, 0, 0.01, 1, 11, 1e-10, 2, 2, 2.01, Infinity, NaN]

And, also, array is changed in-place, which might not be what you want.

  **Error Case:**

var handler = function(parameters) {
  console.log(parameters);
}

(function() {     //IIFE
 // some code
})();

Output: TypeError: (intermediate value)(intermediate value) is not a function *How to Fix IT -> because you are missing semi colan(;) to separate expressions;

 **Fixed**


var handler = function(parameters) {
  console.log(parameters);
}; // <--- Add this semicolon(if you miss that semi colan .. 
   //error will occurs )

(function() {     //IIFE
 // some code
})();

why this error comes?? Reason : specific rules for automatic semicolon insertion which is given ES6 stanards

The data returned by the JSON is in json format : which is simply an arrays of values. Thats why you are seeing [object Object],[object Object],[object Object].

You have to iterate through that values to get actuall value. Like the following

jQuery provides $.each() for iterations, so you could also do this:

$.getJSON("url_with_json_here", function(data){
    $.each(data, function (linktext, link) {
        console.log(linktext);
        console.log(link);
    });
});

Now just create an Hyperlink using that info.

That error is due to missing of modules in pyinstaller. You can find the missing modules by running script in executable command line, i.e., by removing '-w' from the command. Once you created the command line executable file then in command line it will show the missing modules. By finding those missing modules you can add this to your command : " --hidden-import = missingmodule "

I solved my problem through this.

public static System.DateTime getstartweek()
{
    System.DateTime dt = System.DateTime.Now;
    System.DayOfWeek dmon = System.DayOfWeek.Monday;
    int span = dt.DayOfWeek - dmon;
    dt = dt.AddDays(-span);
    return dt;
}

Thanks! @steovi for this solution.

I have added support to ES6 version and changed from unescape to dataURI(unescape is deprecated).

converterDataURItoBlob(dataURI) {
    let byteString;
    let mimeString;
    let ia;

    if (dataURI.split(',')[0].indexOf('base64') >= 0) {
      byteString = atob(dataURI.split(',')[1]);
    } else {
      byteString = encodeURI(dataURI.split(',')[1]);
    }
    // separate out the mime component
    mimeString = dataURI.split(',')[0].split(':')[1].split(';')[0];

    // write the bytes of the string to a typed array
    ia = new Uint8Array(byteString.length);
    for (var i = 0; i < byteString.length; i++) {
      ia[i] = byteString.charCodeAt(i);
    }
    return new Blob([ia], {type:mimeString});
}

@lomaxx: Just to clarify, I'm pretty certain that both above syntax are supported by SQL Serv 2005. The syntax below is NOT supported however

select a.*, b.*  
from table a, table b  
where a.id *= b.id;

Specifically, the outer join (*=) is not supported.

You can also connect via port 465, but due to some limitations of the System.Net.Mail namespace you may have to alter your code. This is because the namespace does not offer the ability to make implicit SSL connections. This is discussed at http://blogs.msdn.com/b/webdav_101/archive/2008/06/02/system-net-mail-with-ssl-to-authenticate-against-port-465.aspx.

It is possible to make implicit connections without having to use the now obsolete System.Web.Mail namespace, but you have to access the Microsoft CDO (Collaborative Data Object). I have supplied an example of how to use the CDO in another discussion (GMail SMTP via C# .Net errors on all ports).

Hope this helps!

Ah, ok. What you're looking for is setHint(int). Simply pass in a resource id of a string from your xml and you're good to go.

EDIT

And in XML, it's simply android:hint="someText"

Cross-posting this as a consolidated reference from the SO Documentation beta which is going offline.

Problem

Cross-site scripting is the unintended execution of remote code by a web client. Any web application might expose itself to XSS if it takes input from a user and outputs it directly on a web page. If input includes HTML or JavaScript, remote code can be executed when this content is rendered by the web client.

For example, if a 3rd party side contains a JavaScript file:

// http://example.com/runme.js
document.write("I'm running");

And a PHP application directly outputs a string passed into it:

<?php
echo '<div>' . $_GET['input'] . '</div>';

If an unchecked GET parameter contains <script src="http://example.com/runme.js"></script> then the output of the PHP script will be:

<div><script src="http://example.com/runme.js"></script></div>

The 3rd party JavaScript will run and the user will see "I'm running" on the web page.

Solution

As a general rule, never trust input coming from a client. Every GET parameter, POST or PUT content, and cookie value could be anything at all, and should therefore be validated. When outputting any of these values, escape them so they will not be evaluated in an unexpected way.

Keep in mind that even in the simplest applications data can be moved around and it will be hard to keep track of all sources. Therefore it is a best practice to always escape output.

PHP provides a few ways to escape output depending on the context.

Filter Functions

PHPs Filter Functions allow the input data to the php script to be sanitized or validated in many ways. They are useful when saving or outputting client input.

HTML Encoding

htmlspecialchars will convert any "HTML special characters" into their HTML encodings, meaning they will then not be processed as standard HTML. To fix our previous example using this method:

<?php
echo '<div>' . htmlspecialchars($_GET['input']) . '</div>';
// or
echo '<div>' . filter_input(INPUT_GET, 'input', FILTER_SANITIZE_SPECIAL_CHARS) . '</div>';

Would output:

<div>&lt;script src=&quot;http://example.com/runme.js&quot;&gt;&lt;/script&gt;</div>

Everything inside the <div> tag will not be interpreted as a JavaScript tag by the browser, but instead as a simple text node. The user will safely see:

<script src="http://example.com/runme.js"></script>

URL Encoding

When outputting a dynamically generated URL, PHP provides the urlencode function to safely output valid URLs. So, for example, if a user is able to input data that becomes part of another GET parameter:

<?php
$input = urlencode($_GET['input']);
// or
$input = filter_input(INPUT_GET, 'input', FILTER_SANITIZE_URL);
echo '<a href="http://example.com/page?input="' . $input . '">Link</a>';

Any malicious input will be converted to an encoded URL parameter.

Using specialised external libraries or OWASP AntiSamy lists

Sometimes you will want to send HTML or other kind of code inputs. You will need to maintain a list of authorised words (white list) and un-authorized (blacklist).

You can download standard lists available at the OWASP AntiSamy website. Each list is fit for a specific kind of interaction (ebay api, tinyMCE, etc...). And it is open source.

There are libraries existing to filter HTML and prevent XSS attacks for the general case and performing at least as well as AntiSamy lists with very easy use. For example you have HTML Purifier

enum A { foo, bar } a;
a = foo;
printf( "%d", a );   // see comments below

None of the answers here worked, I had to:

1. Close android studio
2. rm -rf ./android/.idea
3. Build -> Build Bundle/APK(s) -> Build APK(s)
