Programs & Examples On #Keypress

There's a solution:

import pyautogui
for i in range(1000):
    pyautogui.typewrite("a")

Same functionality i recently achieved using below function.

I wanted to enable SAVE button on edit.

1. Change event is NOT advisable as it will ONLY be fired if after editing, mouse is clicked somewhere else on the page before clicking SAVE button.
2. Key Press doesnt handle Backspace, Delete and Paste options.
3. Key Up handles everything including tab, Shift key.

Hence i wrote below function combining keypress, keyup (for backspace, delete) and paste event for text fields.

Hope it helps you.

function checkAnyFormFieldEdited() {
    /*
     * If any field is edited,then only it will enable Save button
     */
    $(':text').keypress(function(e) { // text written
        enableSaveBtn();
    });

    $(':text').keyup(function(e) {
        if (e.keyCode == 8 || e.keyCode == 46) { //backspace and delete key
            enableSaveBtn();
        } else { // rest ignore
            e.preventDefault();
        }
    });
    $(':text').bind('paste', function(e) { // text pasted
        enableSaveBtn();
    });

    $('select').change(function(e) { // select element changed
        enableSaveBtn();
    });

    $(':radio').change(function(e) { // radio changed
        enableSaveBtn();
    });

    $(':password').keypress(function(e) { // password written
        enableSaveBtn();
    });
    $(':password').bind('paste', function(e) { // password pasted
        enableSaveBtn();
    });


}

Here's how I did it:

var leftKey = 37, upKey = 38, rightKey = 39, downKey = 40;
var keystate;
document.addEventListener("keydown", function (e) {
    keystate[e.keyCode] = true;
});
document.addEventListener("keyup", function (e) {
    delete keystate[e.keyCode];
});

if (keystate[leftKey]) {
//code to be executed when left arrow key is pushed.
}
if (keystate[upKey]) {
//code to be executed when up arrow key is pushed.
}
if (keystate[rightKey]) {
//code to be executed when right arrow key is pushed.
}
if (keystate[downKey]) {
//code to be executed when down arrow key is pushed.
}

Javascript Keycodes

• e.keyCode == 8 for backspace
• e.keyCode == 46 for forward backspace or delete button in PC's

^{Except this detail Colin & Tod's answer is working.}

If you wanted to pass a dynamic param through to a function, inside a dynamic input::

<Input 
  onKeyPress={(event) => {
    if (event.key === "Enter") {
      this.doSearch(data.searchParam)
    }
  }}
  placeholder={data.placeholderText} />
/>

Hope this helps someone. :)

Try:

<table>_x000D_
<tr><td>Key:</td><td id="key"></td></tr>_x000D_
<tr><td>Key Code:</td><td id="keyCode"></td></tr>_x000D_
<tr><td>Event Code:</td><td id="eventCode"></td></tr>_x000D_
</table>_x000D_
<script type="text/javascript">_x000D_
window.addEventListener("keydown", function (e) {_x000D_
  //tested in IE/Chrome/Firefox_x000D_
  document.getElementById("key").innerHTML = e.key;_x000D_
  document.getElementById("keyCode").innerHTML = e.keyCode;_x000D_
  document.getElementById("eventCode").innerHTML = e.code;_x000D_
})_x000D_
</script>

*Note: this works in "Run code snippet"

This website does the same as my code above: Keycode.info

if(characterCode == 13)
{
    return false; // returning false will prevent the event from bubbling up.
}
else
{
    return true;
}

Ok, so imagine you have the following textbox in a form:

<input id="scriptBox" type="text" onkeypress="return runScript(event)" />

In order to run some "user defined" script from this text box when the enter key is pressed, and not have it submit the form, here is some sample code. Please note that this function doesn't do any error checking and most likely will only work in IE. To do this right you need a more robust solution, but you will get the general idea.

function runScript(e) {
    //See notes about 'which' and 'key'
    if (e.keyCode == 13) {
        var tb = document.getElementById("scriptBox");
        eval(tb.value);
        return false;
    }
}

returning the value of the function will alert the event handler not to bubble the event any further, and will prevent the keypress event from being handled further.

NOTE:

It's been pointed out that keyCode is now deprecated. The next best alternative which has also been deprecated.

Unfortunately the favored standard key, which is widely supported by modern browsers, has some dodgy behavior in IE and Edge. Anything older than IE11 would still need a polyfill.

Furthermore, while the deprecated warning is quite ominous about keyCode and which, removing those would represent a massive breaking change to untold numbers of legacy websites. For that reason, it is unlikely they are going anywhere anytime soon.

I'd like to ask why you are trying to detect when the content of the textbox changed in real time?

An alternative would be to set a timer (via setIntval?) and compare last saved value to the current one and then reset a timer. This would guarantee catching ANY change, whether caused by keys, mouse, some other input device you didn't consider, or even JavaScript changing the value (another possiblity nobody mentioned) from a different part of the app.

According to Kilian's answer:

If only enter key-press is important:

<form action="javascript:alert('Enter');">
<input type=text value="press enter">
</form>

I just like to note that I needed this for my Cucumber tests and found out that if you like to simulate pressing the enter/return key, you need to send the :return value and not the :enter value (see the values described here)

You're missing the binding of the method in the constructor. This is how React suggests that you do it:

class Whatever {
  constructor() {
    super();
    this.onKeyPressed = this.onKeyPressed.bind(this);
  }

  onKeyPressed(e) {
    // your code ...
  }

  render() {
    return (<div onKeyDown={this.onKeyPressed} />);
  }
}

There are other ways of doing this, but this will be the most efficient at runtime.

You should assign setTimeout to a variable and use clearTimeout to clear it on keypress.

var timer = '';

$('input#username').keypress(function() {
  clearTimeout(timer);
  timer = setTimeout(function() {
    //Your code here
  }, 3000); //Waits for 3 seconds after last keypress to execute the above lines of code
});

Fiddle

Hope this helps.

If you're using jQuery UI too, you can do like this:

var e = jQuery.Event("keypress");
e.keyCode = $.ui.keyCode.ENTER;
$("input").trigger(e);

KeyPress event is invoked only for character (printable) keys, KeyDown event is raised for all including nonprintable such as Control, Shift, Alt, BackSpace, etc.

UPDATE:

The keypress event is fired when a key is pressed down and that key normally produces a character value

Reference.

Angular supports this out of the box. Have you tried ngSubmit on your form element?

<form ng-submit="myFunc()" ng-controller="mycontroller">
   <input type="text" ng-model="name" />
    <br />
    <input type="text" ng-model="email" />
</form>

EDIT: Per the comment regarding the submit button, see Submitting a form by pressing enter without a submit button which gives the solution of:

<input type="submit" style="position: absolute; left: -9999px; width: 1px; height: 1px;"/>

If you don't like the hidden submit button solution, you'll need to bind a controller function to the Enter keypress or keyup event. This normally requires a custom directive, but the AngularUI library has a nice keypress solution set up already. See http://angular-ui.github.com/

After adding the angularUI lib, your code would be something like:

<form ui-keypress="{13:'myFunc($event)'}">
  ... input fields ...
</form>

or you can bind the enter keypress to each individual field.

Also, see this SO questions for creating a simple keypres directive: How can I detect onKeyUp in AngularJS?

EDIT (2014-08-28): At the time this answer was written, ng-keypress/ng-keyup/ng-keydown did not exist as native directives in AngularJS. In the comments below @darlan-alves has a pretty good solution with:

<input ng-keyup="$event.keyCode == 13 && myFunc()"... />

Java

The Robot class will work much more efficiently than sending the keys through Selenium sendkeys. Please try:

Example:

Robot rb = new Robot();
rb.keyPress(KeyEvent.VK_CONTROL);
rb.keyPress(KeyEvent.VK_A);

To use the above Robot class, you need to import java.awt.Robot;'.

Use keyup instead of keypress. This gets all the key codes when the user presses something

Be aware "document:keypress" is deprecated. We should use document:keydown instead.

Link: https://developer.mozilla.org/fr/docs/Web/API/Document/keypress_event

There is a plugin for Jquery called "Hotkeys" which allows you to bind to key down combinations.

Does this do what you are after?

Jquery HotKeys - Google Code

Please refer the link from JQuery

http://api.jquery.com/keypress/

It says

The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except that modifier and non-printing keys such as Shift, Esc, and delete trigger keydown events but not keypress events. Other differences between the two events may arise depending on platform and browser.

That means you can not use keypress in case of arrows.

Use PyGame to have a window and then you can get the key events.

For the letter p:

import pygame, sys
import pygame.locals

pygame.init()
BLACK = (0,0,0)
WIDTH = 1280
HEIGHT = 1024
windowSurface = pygame.display.set_mode((WIDTH, HEIGHT), 0, 32)

windowSurface.fill(BLACK)

while True:
    for event in pygame.event.get():
        if event.key == pygame.K_p: # replace the 'p' to whatever key you wanted to be pressed
             pass #Do what you want to here
        if event.type == pygame.locals.QUIT:
             pygame.quit()
             sys.exit()

Here example on plain JS:

document.querySelector('#myDiv').addEventListener('keyup', function (e) {_x000D_
  console.log(e.key)_x000D_
})

#myDiv {_x000D_
  outline: none;_x000D_
}

<div _x000D_
  id="myDiv"_x000D_
  tabindex="0"_x000D_
>_x000D_
  Press me and start typing_x000D_
</div>

See parallel. Its syntax is similar to xargs, but it runs the commands in parallel.

itertools.combinations is your friend if you have Python 2.6 or greater. Otherwise, check the link for an implementation of an equivalent function.

import itertools
def findsubsets(S,m):
    return set(itertools.combinations(S, m))

S: The set for which you want to find subsets
m: The number of elements in the subset

write java program that enter elapsed time in seconds for any cycling event & the output format should be like (hour : minute : seconds ) for EX : elapsed time in 4150 seconds= 1:09:10

This worked fine for me:

        $('#myelement').datetimepicker({
            dateFormat: "yy-mm-dd",
            timeFormat:  "hh:mm:ss"
        });

I was looking for an solution to make an XHR request to a server from a local html file and found a solution using Chrome and PHP. (no Jquery)

Javascripts:

var x = new XMLHttpRequest(); 
if(x) x.onreadystatechange=function(){ 
    if (x.readyState === 4 && x.status===200){
        console.log(x.responseText); //Success
    }else{ 
        console.log(x); //Failed
    }
};
x.open(GET, 'http://example.com/', true);
x.withCredentials = true;
x.send();

My Chrome's request header Origin: null

My PHP response header (Note that 'null' is a string). HTTP_REFERER allow cross-origin from a remote server to another.

header('Access-Control-Allow-Origin: '.(trim($_SERVER['HTTP_REFERER'],'/')?:'null'),true);
header('Access-Control-Allow-Credentials:true',true);

I was able to successfully connect to my server. You can disregards the Credentials headers, but this works for me with Apache's AuthType Basic enabled

I tested compatibility with FF and Opera, It works in many cases such as:

From a VM LAN IP (192.168.0.x) back to the VM'S WAN (public) IP:port
From a VM LAN IP back to a remote server domain name.
From a local .HTML file to the VM LAN IP and/or VM WAN IP:port,
From a local .HTML file to a remote server domain name.
And so on.

In general, this is probably not a great idea, since your html file should only be loading JS files that they actually make use of. Regardless, this would be trivial to do with any server-side scripting language. Just insert the script tags before serving the pages to the client.

If you want to do it without using server-side scripting, you could drop your JS files into a directory that allows listing the directory contents, and then use XMLHttpRequest to read the contents of the directory, and parse out the file names and load them.

Option #3 is to have a "loader" JS file that uses getScript() to load all of the other files. Put that in a script tag in all of your html files, and then you just need to update the loader file whenever you upload a new script.

You can do it with Linq, as mamoo showed, but the oldies are good too:

var filteredDataTable = dt.Select(@"EmpId > 2
    AND (EmpName <> 'abc' OR EmpName <> 'xyz')
    AND EmpName like '%il%'" );

<?php

// do something here

header("Location: http://example.com/thankyou.php");
?>

If you want to write a loop in Python which prints some integer no etc, then just copy and paste this code, it'll work a lot

# Display Value from 1 TO 3  
for i in range(1,4):
    print "",i,"value of loop"

# Loop for dictionary data type
  mydata = {"Fahim":"Pakistan", "Vedon":"China", "Bill":"USA"  }  
  for user, country in mydata.iteritems():
    print user, "belongs to " ,country

For me this perfectly triggers slide event on UI Slider :

hs=$('#height_slider').slider();
hs.slider('option', 'value',h);
hs.slider('option','slide')
       .call(hs,null,{ handle: $('.ui-slider-handle', hs), value: h });

Don't forget to set value by hs.slider('option', 'value',h); before the trigger. Else slider handler will not be in sync with value.

One thing to note here is that h is index/position (not value) in case you are using html select.

Using REGEX you can remove the spaces in a string.

The following namespace is mandatory.

using System.Text.RegularExpressions;

Syntax:

Regex.Replace(text, @"\s", "")

var fs = require("fs");
var filename = "./index.html";

function start(resp) {
    resp.writeHead(200, {
        "Content-Type": "text/html"
    });
    fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        resp.write(data);
        resp.end();
    });
}

Python 2.X

dict((k, v) for k, v in metadata.iteritems() if v)

Python 2.7 - 3.X

{k: v for k, v in metadata.items() if v is not None}

Note that all of your keys have values. It's just that some of those values are the empty string. There's no such thing as a key in a dict without a value; if it didn't have a value, it wouldn't be in the dict.

You can use this command:

grep -rn "string" *

n for showing line number with the filename r for recursive

How about calling the .NET Framework methods?

You can do ANYTHING with them... :

[System.IO.File]::Copy($src, $dest, $true);

The $true argument makes it overwrite.

Simple Use PHP function (imagescale):

Syntax:

imagescale ( $image , $new_width , $new_height )

Example:

Step: 1 Read the file

$image_name =  'path_of_Image/Name_of_Image.jpg|png';      

Step: 2: Load the Image File

 $image = imagecreatefromjpeg($image_name); // For JPEG
//or
 $image = imagecreatefrompng($image_name);   // For PNG

Step: 3: Our Life-saver comes in '_' | Scale the image

   $imgResized = imagescale($image , 500, 400); // width=500 and height = 400
//  $imgResized is our final product

Note: imagescale will work for (PHP 5 >= 5.5.0, PHP 7)

No valid Kits found The problem occurs because qt-creator don't know the versions of your qt, your compiler or your debugger. First off, let's solve the Qt versions. It may normally solve the others too ;).

You try to create a new project, run select a kit and then there is no kit available in the list.

Follow the steps:

1. Execute in your terminal the command: sudo apt-get install qt5-default to install qt version 5.
2. Verify the version of your Qt and the location of your qmake file. Do this by executing in your terminal the command qmake --version. You may have a result similar to this line. QMake version 3.1 Using Qt version 5.9.5 in /usr/lib/x86_64-linux-gnu. What's important here is the location /usr/lib/x86_64-linux-gnu.
3. Open your Qt-creator.
4. Go to "Tools>Options" or "Outils>Options"
5. Select the Qt Versions combobox and select and click "Add" or "Ajouter"
6. Then find the qmake file in the location of step 2. Here /usr/lib/x86_64-linux-gnu/qt5/bin/ here you have the qmake file for qt5. Open it, click Apply.
7. Go to "Kits" combobox. Select Desktop(by default) or Desktop(par défaut). Then scroll down to the button to select Qt version: and list down to select the version you just add. 8.Then apply all. Check your compiler and debugger and it's ok. You're done.

Yes I ...

Hope it's help ;)

For me, the issue was being inside a conda environment. Most likely it used the pip command from the conda environment ("where pip" pointed to the conda environment). Setting proxy-settings via --proxy or set http_proxy did not help.

Instead, simply opening a new CMD and doing "pip install " there, helped.

It's been 10 years since this question was asked. And I hope this answer will be useful to someone. As mentioned in the answer here, where GUI is not an option, Andrew Shadura's crecord extension helps bring a ncurses window in which we can select the lines to commit.

Set up the extension as follows:

git clone https://github.com/andrewshadura/git-crecord
cd git-crecord
./setup.py install
ln -s $PWD/git-crecord ~/.local/bin/git-crecord

cd to your git repo and invoke it as follows:

git crecord

This would bring up the ncurses interface which can be used as shown below. Pressing the following keys in the ncurses window will do certain actions:

f       hunk toggle fold (arrow keys can also be used)
space   toggle hunk selection
a       toggle commit or amend
c       confirm and open commit window

The most common representations are probably these two:

• Adjacency list

• Adjacency matrix

Of these two the adjacency matrix is the simplest, as long as you don't mind having a (possibly huge) n * n array, where n is the number of vertices. Depending on the base type of the array, you can even store edge weights for use in e.g. shortest path discovery algorithms.

You cannot add a column with a default value in Hive. You have the right syntax for adding the column ALTER TABLE test1 ADD COLUMNS (access_count1 int);, you just need to get rid of default sum(max_count). No changes to that files backing your table will happen as a result of adding the column. Hive handles the "missing" data by interpreting NULL as the value for every cell in that column.

So now your have the problem of needing to populate the column. Unfortunately in Hive you essentially need to rewrite the whole table, this time with the column populated. It may be easier to rerun your original query with the new column. Or you could add the column to the table you have now, then select all of its columns plus value for the new column.

You also have the option to always COALESCE the column to your desired default and leave it NULL for now. This option fails when you want NULL to have a meaning distinct from your desired default. It also requires you to depend on always remembering to COALESCE.

If you are very confident in your abilities to deal with the files backing Hive, you could also directly alter them to add your default. In general I would recommend against this because most of the time it will be slower and more dangerous. There might be some case where it makes sense though, so I've included this option for completeness.

Add the below code in your page. Trust me, no changes made to button events, to disable/enable button simply add/remove the button class in Javascript.

Method 1

 <asp Button ID="btnSave" CssClass="disabledContent" runat="server" />

<style type="text/css">
    .disabledContent 
    {
        cursor: not-allowed;
        background-color: rgb(229, 229, 229) !important;
    }

    .disabledContent > * 
    {
        pointer-events:none;
    }
</style>

Method 2

<asp Button ID="btnSubmit" CssClass="btn-disable" runat="server" />

<style type="text/css">
    .btn-disable
        {
        cursor: not-allowed;
        pointer-events: none;

        /*Button disabled - CSS color class*/
        color: #c0c0c0;
        background-color: #ffffff;

        }
</style>

Couldn't you just write all the commands into a .cmd file in the temp folder and then execute that file?

I used to use the PGP disk encryption product on a laptop (and ran NTFS compressed on top of that!). It didn't seem to have much effect if the amount of disk to be read was small; and most software sources aren't huge by disk standards.

You have lots of RAM and pretty fast processors. I spent most of my time thinking, typing or debugging.

I wouldn't worry very much about it.

 $('.AlphabetsOnly').keypress(function (e) {
        var regex = new RegExp(/^[a-zA-Z\s]+$/);
        var str = String.fromCharCode(!e.charCode ? e.which : e.charCode);
        if (regex.test(str)) {
            return true;
        }
        else {
            e.preventDefault();
            return false;
        }
    });

If by string you mean std::string you can do it with this method:

QString QString::fromStdString(const std::string & str)

std::string str = "Hello world";
QString qstr = QString::fromStdString(str);

If by string you mean Ascii encoded const char * then you can use this method:

QString QString::fromAscii(const char * str, int size = -1)

const char* str = "Hello world";
QString qstr = QString::fromAscii(str);

If you have const char * encoded with system encoding that can be read with QTextCodec::codecForLocale() then you should use this method:

QString QString::fromLocal8Bit(const char * str, int size = -1)

const char* str = "zazólc gesla jazn";      // latin2 source file and system encoding
QString qstr = QString::fromLocal8Bit(str);

If you have const char * that's UTF8 encoded then you'll need to use this method:

QString QString::fromUtf8(const char * str, int size = -1)

const char* str = read_raw("hello.txt"); // assuming hello.txt is UTF8 encoded, and read_raw() reads bytes from file into memory and returns pointer to the first byte as const char*
QString qstr = QString::fromUtf8(str);

There's also method for const ushort * containing UTF16 encoded string:

QString QString::fromUtf16(const ushort * unicode, int size = -1)

const ushort* str = read_raw("hello.txt"); // assuming hello.txt is UTF16 encoded, and read_raw() reads bytes from file into memory and returns pointer to the first byte as const ushort*
QString qstr = QString::fromUtf16(str);

I had similar situation. Writing custom filter worked for me. Hope this helps!

JS:

App.filter('searchMovies', function() {
    return function (items, letter) {
        var resulsts = [];
        var itemMatch = new RegExp(letter, 'i');
        for (var i = 0; i < items.length; i++) {
            var item = items[i];
            if ( itemMatch.test(item.name) || itemMatch.test(item.genre)) {
                results.push(item);
            }
        }
        return results;
    };
});

HTML:

<div ng-controller="MoviesCtrl">
    <ul>
        <li ng-repeat="movie in movies | searchMovies:filterByGenres">
            {{ movie.name }} {{ movie.genre }}
        </li>
    </ul>
</div>

Here's the solution that works fine for me.

I just Saved the Excel file as an Excel 97-2003 Version.

Make your object something like

public class MyObject : IComparable
{
    public string a;
    public string b;

    virtual public int CompareTo(object obj)
    {
        if (obj is MyObject)
        {
            var compareObj = (MyObject)obj;
            if (this.a.CompareTo(compareObj.a) == 0)
            {
                // compare second value
                return this.b.CompareTo(compareObj.b);
            }
            return this.a.CompareTo(compareObj.b);
        }
        else
        {
            throw new ArgumentException("Object is not a MyObject ");
        }
    }
}

also note that the returns for CompareTo :

http://msdn.microsoft.com/en-us/library/system.icomparable.compareto.aspx

Then, if you have a List of MyObject, call .Sort() ie

var objList = new List<MyObject>();
objList.Sort();

Find the index of the columns you want to drop using which. Give these indexes a negative sign (*-1). Then subset on those values, which will remove them from the dataframe. This is an example.

DF <- data.frame(one=c('a','b'), two=c('c', 'd'), three=c('e', 'f'), four=c('g', 'h'))
DF
#  one two three four
#1   a   d     f    i
#2   b   e     g    j

DF[which(names(DF) %in% c('two','three')) *-1]
#  one four
#1   a    g
#2   b    h

Environment variables are now part of the "scheme".

To edit the scheme and turn on zombies:

• In the "Product" menu, select "Edit Scheme".

• Go to the "Run Foo.app" stage in the left panel, and the "Arguments" tab on the right.

• Add NSZombieEnabled to the "Environment Variables" section and set the value to YES, as you could in Xcode 3.

In Xcode 4.1 and above, there's also a checkbox on the "Diagnostics" tab of the "Run" stage to "Enable Zombie Objects".

With Xcode 6.4:

This is how I applied the code snippet below and it's working fine. Hope, this would help somebody.

<EditText 
    android:id="@+id/EditText02"
    android:gravity="top|left" 
    android:inputType="textMultiLine"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:lines="5" 
    android:scrollHorizontally="false" 
/>

Cheers! ...Thanks.

If you are looking for a scripted solution:

1. Get binary download URL: you can use an API, but be warned that there is no documentation for it. This API can return an URL to download .vsix files (see example below)
2. Download the binary
3. Carefully unzip the binary into ~/.vscode/extensions/: you need to modify unzipped directory name, remove one file and move/rename another one.

For API start by looking at following example, and for hints how to modify request head to https://github.com/Microsoft/vscode/blob/master/src/vs/platform/extensionManagement/common/extensionGalleryService.ts.

    "filters": [
        {
        "criteria": [
            {
                "filterType": 8,
                "value": "Microsoft.VisualStudio.Code",
            },
            {
                "filterType": 7,
                "value": "ms-python.python",

        }
    ],
    "assetTypes": ["Microsoft.VisualStudio.Services.VSIXPackage"],
    "flags": 514,
}

Explanations to the above example:

• "filterType": 8 - FilterType.Target more FilterTypes
• "filterType": 7 - FilterType.ExtensionName more FilterTypes
• "flags": 514 - 0x2 | 0x200 - Flags.IncludeFiles | Flags.IncludeLatestVersionOnly - more Flags
  • to get flag decimal value you can run python -c "print(0x2|0x200)"
• "assetTypes": ["Microsoft.VisualStudio.Services.VSIXPackage"] - to get only link to .vsix file more AssetTypes

Configuration worked with Eclipse Mars 4.5 version.

1) Install Eclipse Mars 4.5 from https://eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/mars2 This comes with Tern and embedded Node.js server

2) Install AngularJS Eclipse plugin from Eclipse Marketplace

3) Configure node.js server to the embedded nodejs server within Eclipse (found in the eclipse plugins folder) at Windows-> Preferences -> JavaScript -> Tern -> Server -> node.js. No extra configurations are required.

4) Test configuration in a html or javascript file. https://github.com/angelozerr/angularjs-eclipse

I recommended an experimental new attribute CSS I tested on latest browser and it's good:

image-rendering: optimizeSpeed;             /*                     */
image-rendering: -moz-crisp-edges;          /* Firefox             */
image-rendering: -o-crisp-edges;            /* Opera               */
image-rendering: -webkit-optimize-contrast; /* Chrome (and Safari) */
image-rendering: optimize-contrast;         /* CSS3 Proposed       */
-ms-interpolation-mode: nearest-neighbor;   /* IE8+                */

With this the browser will know the algorithm for rendering

you need to cast int to str before concatenating. for that use str(temperature). Or you can print the same output using , if you don't want to convert like this.

print("the furnace is now",temperature , "degrees!")

Hey please add code in your project,it is easy and i think will solve your problem.

    int count = 10;

    private void timer1_Tick(object sender, EventArgs e)
    {
        count--;
        if (count != 0 && count > 0)
        {
            label1.Text = count / 60 + ":" + ((count % 60) >= 10 ? (count % 60).ToString() : "0" + (count % 60));
        }
        else
        {
            label1.Text = "game over";

        }

    }

    private void Form1_Load(object sender, EventArgs e)
    {
        timer1 = new System.Windows.Forms.Timer();
        timer1.Interval = 1;

        timer1.Tick += new EventHandler(timer1_Tick);

    }

You've already stated why np.maximum is different - it returns an array that is the element-wise maximum between two arrays.

As for np.amax and np.max: they both call the same function - np.max is just an alias for np.amax, and they compute the maximum of all elements in an array, or along an axis of an array.

In [1]: import numpy as np

In [2]: np.amax
Out[2]: <function numpy.core.fromnumeric.amax>

In [3]: np.max
Out[3]: <function numpy.core.fromnumeric.amax>

sudo apt-get install docker # DO NOT do this

is a different library on ubuntu.

Use sudo apt-get install docker-ce to install the correct docker.

The problem is still is recursive on Ubuntu 13/04/13.10/14.04

and

sudo apt-get install ruby1.9.1-dev

worked out for me okay. So If you are using Ubuntu 13.04/13.10/14.04 then using this will really come in handy.

This works even if ruby version is 1.9.3. This is because there is no ruby1.9.3-dev available in the Repository...

Assuming a is a string. The Slice notation in python has the syntax -

list[<start>:<stop>:<step>]

So, when you do a[::-1], it starts from the end towards the first taking each element. So it reverses a. This is applicable for lists/tuples as well.

Example -

>>> a = '1234'
>>> a[::-1]
'4321'

Then you convert it to int and then back to string (Though not sure why you do that) , that just gives you back the string.

try this one if there is tbody

Without Header

$("#myTable > tbody").children.length

If there is header then

$("#myTable > tbody").children.length -1

Enjoy!!!

The said method with highest up's by Laz is deprecated from version 4.3 onwards. Hence it would be better to user the Request Config Object and then build the HTTP Client

    private CloseableHttpClient createHttpClient()
        {
        CloseableHttpClient httpClient;
        CommonHelperFunctions helperFunctions = new CommonHelperFunctions();
        PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();
        cm.setMaxTotal(306);
        cm.setDefaultMaxPerRoute(108);
        RequestConfig requestConfig = RequestConfig.custom()
            .setConnectTimeout(15000)
            .setSocketTimeout(15000).build();
        httpClient = HttpClients.custom()
            .setConnectionManager(cm)
            .setDefaultRequestConfig(requestConfig).build();
        return httpClient;
        }

The PoolingHttpClientConnectionManager is user to set the max default number of connections and the max number of conncetions per route. I have set it as 306 and 108 respectively. The default values will not be sufficient for most of the cases.

For setting Timeout: I have used the RequestConfig object. You can also set the property Connection Request Timeout for setting timeout for waiting for connection from Connection manager.

Here's a updated DOB function, which calculates birthdays the same way humans do:

import datetime
import locale


# Source: https://en.wikipedia.org/wiki/February_29
PRE = [
    'US',
    'TW',
]
POST = [
    'GB',
    'HK',
]


def get_country():
    code, _ = locale.getlocale()
    try:
        return code.split('_')[1]
    except IndexError:
        raise Exception('Country cannot be ascertained from locale.')


def get_leap_birthday(year):
    country = get_country()
    if country in PRE:
        return datetime.date(year, 2, 28)
    elif country in POST:
        return datetime.date(year, 3, 1)
    else:
        raise Exception('It is unknown whether your country treats leap year '
                      + 'birthdays as being on the 28th of February or '
                      + 'the 1st of March. Please consult your country\'s '
                      + 'legal code for in order to ascertain an answer.')
def age(dob):
    today = datetime.date.today()
    years = today.year - dob.year

    try:
        birthday = datetime.date(today.year, dob.month, dob.day)
    except ValueError as e:
        if dob.month == 2 and dob.day == 29:
            birthday = get_leap_birthday(today.year)
        else:
            raise e

    if today < birthday:
        years -= 1
    return years

print(age(datetime.date(1988, 2, 29)))

On Windows 10 - This happened for me after the latest update in 2020.

What solved this issue for me was running the following in PowerShell

C:\>Install-Module -Name MicrosoftPowerBIMgmt

UPDATE:

The below answer references the state of things before widespread availability of CSS 3. In modern browsers (including Internet Explorer 9 and later) it is more straightforward to create checkbox replacements with your preferred styling, without using JavaScript.

Here are some useful links:

• Creating Custom Form Checkboxes with Just CSS
• Easy CSS Checkbox Generator
• Stuff You Can Do With The Checkbox Hack
• Implementing Custom Checkboxes and Radio Buttons with CSS3
• How to Style a Checkbox With CSS

It is worth noting that the fundamental issue has not changed. You still can't apply styles (borders, etc.) directly to the checkbox element and have those styles affect the display of the HTML checkbox. What has changed, however, is that it's now possible to hide the actual checkbox and replace it with a styled element of your own, using nothing but CSS. In particular, because CSS now has a widely supported :checked selector, you can make your replacement correctly reflect the checked status of the box.

OLDER ANSWER

Here's a useful article about styling checkboxes. Basically, that writer found that it varies tremendously from browser to browser, and that many browsers always display the default checkbox no matter how you style it. So there really isn't an easy way.

It's not hard to imagine a workaround where you would use JavaScript to overlay an image on the checkbox and have clicks on that image cause the real checkbox to be checked. Users without JavaScript would see the default checkbox.

Edited to add: here's a nice script that does this for you; it hides the real checkbox element, replaces it with a styled span, and redirects the click events.

double-quote asterisk ("*) before any yank command will yank the results into the copy buffer. That works for Windows and Linux too.

Just setting Skip Install to YES did not work for me. Hopefully this will help somebody.

I went to dependence of my project targets: Coreplot-CocoaTouch. Then went to Coreplot-CocoaTouch Targets. In its Targets opened Build Phases. Then opened Copy Headers. There I had some of headers in Public, some in Private and some in Project. Moved ALL of them to Project.

Of course, in Build Settings of Coreplot-CocoaTouch Targets checked that Skip Install was set to YES in Deployment options.

And this time Archive made an archive that could be signed and .ipa produced.

I would suggest using R and the package RSQLite

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

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

dbListTables(exampledb)

Why not pass an object to v-bind:class to dynamically toggle the class:

<div v-bind:class="{ disabled: order.cancelled_at }"></div>

This is what is recommended by the Vue docs.

x = int(input("Give starting number: "))
y = int(input("Give ending number: "))

for i in range(x, y):
    print(i)

This outputs:

DISTINCT is always a right choice to get unique values. Also you can do it alternatively without using it. That's GROUP BY. Which has simply add at the end of the query and followed by the column name.

SELECT * FROM buy GROUP BY date,description

If you take a look at @types/node-fetch you will see the body definition

export class Body {
    bodyUsed: boolean;
    body: NodeJS.ReadableStream;
    json(): Promise<any>;
    json<T>(): Promise<T>;
    text(): Promise<string>;
    buffer(): Promise<Buffer>;
}

That means that you could use generics in order to achieve what you want. I didn't test this code, but it would looks something like this:

import { Actor } from './models/actor';

fetch(`http://swapi.co/api/people/1/`)
      .then(res => res.json<Actor>())
      .then(res => {
          let b:Actor = res;
      });

The marked answer is the correct one. However, Pricey, you should follow up on this with your AD and desktop admin groups. They are misusing the IE11 Enterprise Mode site list. Microsoft does NOT intend it to be used for all intranet sites within an organization at all. That would be propagating the existing "render all intranet sites in compatibility mode" setting that is the bane of corporate website advancement the world over.

It's meant to implemented as a "Black list", with the handful of sites that actually require a legacy browser mode listed in the Enterprise Mode list with their rendering requirements specified. All other sites in your organization are then freed up to use Edge. The people in your organization who implemented it with all intranet sites included to start with have completely misunderstood how Enterprise Mode is meant to be implemented.

Close the IDE and open it again. This works if you did not use any code coverage tools and have just clicked the basic "Coverage" icon in the IDE.

You can use a position: absolute inside a position: relative

https://codepen.io/Iquixe/pen/RwRzGrM

Wrong. That doesn't work for me.

For me this one works:

curl 
-H 'SOAPACTION: "urn:samsung.com:service:MainTVAgent2:1#CheckPIN"'   
-X POST 
-H 'Content-type: text/xml'   
-d @/tmp/pinrequest.xml 
192.168.1.5:52235/MainTVServer2/control/MainTVAgent2

If you compile multiple files in the same line, ensure that you use javac only once and not for every class file.

Incorrect:

Correct:

It would appear this is not possible, or at least not supported.

From the HTML5 specification:

When used to include data blocks (as opposed to scripts), the data must be embedded inline, the format of the data must be given using the type attribute, the src attribute must not be specified, and the contents of the script element must conform to the requirements defined for the format used.

Use datetime.replace:

from datetime import datetime
dt = datetime.strptime('26 Sep 2012', '%d %b %Y')
newdatetime = dt.replace(hour=11, minute=59)

If it is related to the SSIS Package check may be possible that your source db contains few null rows. After removing them this issue will not appear any more.

None of above worked for me, because tint was cleared after click. I had to use

button.setImageTintColor(Palette.darkGray(), for: UIControlState())

Have you tried using the !important flag on the style? !important allows you to decide which style will win out. Also note !important will override inline styles as well.

#example p {
    color: blue !important;
}
...
#example p {
    color: red;
}

Another couple suggestions:

Add a span inside of the current. The inner most will win out. Although this could get pretty ugly.

<span class="style21">
<span style="position:absolute;top:432px;left:422px; color:Red" >relating to</span>
</span>

jQuery is also an option. The jQuery library will inject the style attribute in the targeted element.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js" type="text/javascript" ></script>
    <script type="text/javascript">

        $(document).ready(function() {
            $("span").css("color", "#ff0000");
        });

    </script>

Hope this helps. CSS can be pretty frustrating at times.

You should write :

if (self.a != 0) and (self.b != 0) :

"&" is the bit wise operator and does not suit for boolean operations. The equivalent of "&&" is "and" in Python.

A shorter way to check what you want is to use the "in" operator :

if 0 not in (self.a, self.b) :

You can check if anything is part of a an iterable with "in", it works for :

• Tuples. I.E : "foo" in ("foo", 1, c, etc) will return true
• Lists. I.E : "foo" in ["foo", 1, c, etc] will return true
• Strings. I.E : "a" in "ago" will return true
• Dict. I.E : "foo" in {"foo" : "bar"} will return true

As an answer to the comments :

Yes, using "in" is slower since you are creating an Tuple object, but really performances are not an issue here, plus readability matters a lot in Python.

For the triangle check, it's easier to read :

0 not in (self.a, self.b, self.c)

Than

(self.a != 0) and (self.b != 0) and (self.c != 0) 

It's easier to refactor too.

Of course, in this example, it really is not that important, it's very simple snippet. But this style leads to a Pythonic code, which leads to a happier programmer (and losing weight, improving sex life, etc.) on big programs.

using from ListSelectionModel:

ListSelectionModel cellSelectionModel = table.getSelectionModel();
cellSelectionModel.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

cellSelectionModel.addListSelectionListener(new ListSelectionListener() {
  public void valueChanged(ListSelectionEvent e) {
    String selectedData = null;

    int[] selectedRow = table.getSelectedRows();
    int[] selectedColumns = table.getSelectedColumns();

    for (int i = 0; i < selectedRow.length; i++) {
      for (int j = 0; j < selectedColumns.length; j++) {
        selectedData = (String) table.getValueAt(selectedRow[i], selectedColumns[j]);
      }
    }
    System.out.println("Selected: " + selectedData);
  }

});

see here.

In Swing its fairly common to write a class that implements ActionListener and add the current instance (ie 'this') as an ActionListener for components.

public class MyDialog extends JDialog implements ActionListener
{
    public MyDialog()
    {
        JButton myButton = new JButton("Hello");
        myButton.addActionListener(this);
    }

    public void actionPerformed(ActionEvent evt)
    {
        System.out.println("Hurdy Gurdy!");
    }

}

In Swift 2.0:

func deleteAllData(entity: String)
{
    let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
    let managedContext = appDelegate.managedObjectContext
    let fetchRequest = NSFetchRequest(entityName: entity)
    fetchRequest.returnsObjectsAsFaults = false

    do 
    {
        let results = try managedContext.executeFetchRequest(fetchRequest)
        for managedObject in results
        {
            let managedObjectData:NSManagedObject = managedObject as! NSManagedObject
            managedContext.deleteObject(managedObjectData)
        }
    } catch let error as NSError {
        print("Detele all data in \(entity) error : \(error) \(error.userInfo)")
    }
}

Here is a snippet I wrote; to ask for users' password and set it in /etc/passwd. You can manipulate it a little probably to get what you need:

echo -n " Please enter the password for the given user: "
read userPass
useradd $userAcct && echo -e "$userPass\n$userPass\n" | passwd $userAcct > /dev/null 2>&1 && echo " User account has been created." || echo " ERR -- User account creation failed!"

This error occurs because of some file corruption. But we don't need to delete whole .m2 folder. Instead find which jar files get corrupted by looking at the error message in the console. And delete only the folders which contains those jar files.

Like in the question :

1. C:\Users\suresh\.m2\repository\org\jdom\jdom\
2. C:\Users\suresh\.m2\repository\javax\servlet\servlet-api\
3. C:\Users\suresh\.m2\repository\org\apache\cxf\cxf-rt-bindings-http
4. C:\Users\suresh\.m2\repository\org\codehaus\jra\jra
5. C:\Users\suresh\.m2\repository\org\apache\cxf\cxf-api
6. C:\Users\suresh\.m2\repository\org\apache\cxf\cxf-common-utilities

Delete these folders. Then run.

mvn clean install -U

You need to check out a previous version from before you deleted the files. Try git checkout HEAD^ to checkout the last revision.

In openCV whenever you try to display an oversized image or image bigger than your display resolution you get the cropped display. It's a default behaviour.
In order to view the image in the window of your choice openCV encourages to use named window. Please refer to namedWindow documentation

The function namedWindow creates a window that can be used as a placeholder for images and trackbars. Created windows are referred to by their names.

cv.namedWindow(name, flags=CV_WINDOW_AUTOSIZE) where each window is related to image container by the name arg, make sure to use same name

eg:

import cv2
frame = cv2.imread('1.jpg')
cv2.namedWindow("Display 1")
cv2.resizeWindow("Display 1", 300, 300)
cv2.imshow("Display 1", frame)

What is the difference between left join and left outer join?

Nothing. LEFT JOIN and LEFT OUTER JOIN are equivalent.

The git blame command is used to know who/which commit is responsible for the latest changes made to a file. The author/commit of each line can also been seen.

git blame filename (commits responsible for changes for all lines in code)

git blame filename -L 0,10 (commits responsible for changes from line "0" to line "10")

There are many other options for blame, but generally these could help.

Nathan's code but for jQuery Validate plugin

If you happen to use jQuery Validate plugin, they already have submit handler implemented, and in that case there is no reason to implement more than one. The code:

jQuery.validator.setDefaults({
  submitHandler: function(form){
    // Prevent double submit
    if($(form).data('submitted')===true){
      // Previously submitted - don't submit again
      return false;
    } else {
      // Mark form as 'submitted' so that the next submit can be ignored
      $(form).data('submitted', true);
      return true;
    }
  }
});

You can easily expand it within the } else {-block to disable inputs and/or submit button.

Cheers

This works for me

while (document.getElementsByClassName('my-class')[0]) {
        document.getElementsByClassName('my-class')[0].remove();
    }

I'd vote for Thread.stop().

As for instance you have a long lasting operation (like a network request). Supposedly you are waiting for a response, but it can take time and the user navigated to other UI. This waiting thread is now a) useless b) potential problem because when he will get result, it's completely useless and he will trigger callbacks that can lead to number of errors.

All of that and he can do response processing that could be CPU intense. And you, as a developer, cannot even stop it, because you can't throw if (Thread.currentThread().isInterrupted()) lines in all code.

So the inability to forcefully stop a thread it weird.

I know question is specific to MVC4. But since we are way past MVC4 and if anyone looking for ASP.NET Core, you can use:

<partial name="_My_Partial" model="Model.MyInfo" />

The answer below is apparently obsolete now, but works with older drivers. See comments.

If you have the connection string you could also use MongoDatabase directly:

If you want to do with ImageButton, use the following. It will create round ImageButton with material ripples.

<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_settings_6"
android:background="?selectableItemBackgroundBorderless"
android:padding="10dp"
/>

You may be calling fragmentManager.popBackStackImmediate(); when activity is paused. Activity is not finished but is paused and not on foreground. You need to check whether activity is paused or not before popBackStackImmediate().

Bootstrap event for modal load was changed in Bootstrap 3

just use shown.bs.modal event:

$('.modal').on('shown.bs.modal', function() {
    $(this).find('iframe').attr('src','http://www.google.com')
})  

More can found on the event at the below link:

go to canvas page.. view it in browser.. copy the address bar text. now go to your facebook app go to edit settings

in website, in site url paste that address

in facebook integration , again paste the that address in canvas url

and also the same code wherever you require canvas url or redirect url..

hope it will help..

A very practical reason is that IE 6 doesn't let you resize the font if it's specified using px, whereas it does if you use a relative unit such as em or percentages. Not allowing the user to resize the font is very bad for accessibility. Although it's in decline, there are still a lot of IE 6 users out there.

Python iterable can be summed like so - [sum(range(10)[1:])] . This sums all elements from the list except the first element.

>>> atuple = (1,2,3,4,5)
>>> sum(atuple)
15
>>> alist = [1,2,3,4,5]
>>> sum(alist)
15

If you are using Float or Integer then you can assign default value like this ...

Integer[] data = new Integer[20];
Arrays.fill(data,new Integer(0));

I solved a similar problem by adding the --trusted-host pypi.python.org option

You can use list ?? Enumerable.Empty<Friend>(), or have FindFriends return Enumerable.Empty<Friend>()

For me it was very important to get email logging working. After some time I discover that this need only 2 lines of code more in Atif example.

public class HandleErrorWithElmahAttribute : HandleErrorAttribute
{
    static ElmahMVCMailModule error_mail_log = new ElmahMVCMailModule();

    public override void OnException(ExceptionContext context)
    {
        error_mail_log.Init(HttpContext.Current.ApplicationInstance);
        [...]
    }
    [...]
}

I hope this will help someone :)

If you need to execute wget just once with the proxy, the easiest way is to do it with a one-liner like this:

http_proxy=http://username:password@proxy_host:proxy_port wget http://fileurl

or with an https target URL:

https_proxy=http://username:password@proxy_host:proxy_port wget https://fileurl

No, you have no way to get the "name" from the value in C++ because all the symbols are discarded during compilation.

It's in fact almost the same in Python.. :-)

import datetime
year = datetime.date.today().year

Of course, date doesn't have a time associated, so if you care about that too, you can do the same with a complete datetime object:

import datetime
year = datetime.datetime.today().year

(Obviously no different, but you can store datetime.datetime.today() in a variable before you grab the year, of course).

One key thing to note is that the time components can differ between 32-bit and 64-bit pythons in some python versions (2.5.x tree I think). So you will find things like hour/min/sec on some 64-bit platforms, while you get hour/minute/second on 32-bit.

Changing the host to 127.0.0.1 worked for me.

Edit the file in /etc/mysql/my.cnf and add the below mentioned line to the section: client

[client]
port  = 3306
host  = 127.0.0.1
socket  = /var/lib/mysql/mysql.sock

After you are done with it. Execute the following command.

sudo service mysql start

This happened to me too.. Sometimes when I open my project this error shown up which was frustrating. The problem was that sometimes the port-number of web service was changing unexpectedly.

This problem usually happens when you have more than one copies of the project

My project was calling the Web service with a specific port number which I assigned in the Web.Config file of my main project file. As the port number changed unexpectedly, the browser was unable to find the Web service and throwing that error.

I solved this by following the below steps: (Visual Studio 2010)

Go to Properties of the Web service project --> click on Web tab --> In Servers section --> Check Specific port and then assign the standard port number by which your main project is calling the web service.

I hope this will solve the problem.

Cheers :)

I'm getting SecurityError: The operation is insecure.

when using canvas.toDataURL('image/jpg'); in safari browser

Using API version 2, which is deprecated, the URL for uploads (of channel UCqAEtEr0A0Eo2IVcuWBfB9g) is:

https://gdata.youtube.com/feeds/users/UCqAEtEr0A0Eo2IVcuWBfB9g/uploads

There is an API version 3.

one posibility: catch the exception and show an error message within the user frontend.

edit: add an listener to the field within the gui and check the user inputs there too, with this solution the exception case should be very rare...

There are 2 inputs you might have and you can also convert between them.

1. input: listOfDictionaries --> use @VikashSingh solution

example: [{"":{"...

The pd.DataFrame() needs a listOfDictionaries as input.

2. input: jsonStr --> use @JustinMalinchak solution

example: '{"":{"...

If you have jsonStr, you need an extra step to listOfDictionaries first. This is obvious as it is generated like:

jsonStr = json.dumps(listOfDictionaries)

Thus, switch back from jsonStr to listOfDictionaries first:

listOfDictionaries = json.loads(jsonStr)

From official documentation, FailedPreconditionError

This exception is most commonly raised when running an operation that reads a tf.Variable before it has been initialized.

In your case the error even explains what variable was not initialized: Attempting to use uninitialized value Variable_1. One of the TF tutorials explains a lot about variables, their creation/initialization/saving/loading

Basically to initialize the variable you have 3 options:

• initialize all global variables with tf.global_variables_initializer()
• initialize variables you care about with tf.variables_initializer(list_of_vars). Notice that you can use this function to mimic global_variable_initializer: tf.variable_initializers(tf.global_variables())
• initialize only one variable with var_name.initializer

I almost always use the first approach. Remember you should put it inside a session run. So you will get something like this:

with tf.Session() as sess:
    sess.run(tf.global_variables_initializer())

If your are curious about more information about variables, read this documentation to know how to report_uninitialized_variables and check is_variable_initialized.

Just try to run openssl.exe as administrator.

There are probably a few ways to do this, but one approach would be to merge the two dataframes together on the filename/m column, then populate the column 'n' from the right dataframe if a match was found. The n_x, n_y in the code refer to the left/right dataframes in the merge.

In[100] : df = pd.merge(df1, df2, how='left', on=['filename','m'])

In[101] : df
Out[101]: 
    filename   m   n_x  n_y
0  test0.dat  12  None  NaN
1  test2.dat  13  None   16

In[102] : df['n'] = df['n_y'].fillna(df['n_x'])

In[103] : df = df.drop(['n_x','n_y'], axis=1)

In[104] : df
Out[104]: 
    filename   m     n
0  test0.dat  12  None
1  test2.dat  13    16

You can simply create a bat file in any convenient place and drop any file from the desired directory onto it. Haha. Code for this:

cmd

In the for, you have an iteration, then for each element of that loop which probably is a scalar, has no index. When each element is an empty array, single variable, or scalar and not a list or array you cannot use indices.

If you want to use the same function on different events the following code block can be used

$('input').on('keyup blur focus', function () {
   //function block
})

You should not throw an ArithmeticException. Since the error is in the supplied arguments, throw an IllegalArgumentException. As the documentation says:

Thrown to indicate that a method has been passed an illegal or inappropriate argument.

Which is exactly what is going on here.

if (divisor == 0) {
    throw new IllegalArgumentException("Argument 'divisor' is 0");
}

Try the following:

print "First is: %f" % (first)
print "Second is: %f" % (second)

I am unsure what answer is. But apart from that, this will be:

print "DONE: %f DIVIDED BY %f EQUALS %f, SWEET MATH BRO!" % (first, second, ans)

There's a lot of text on Format String Specifiers. You can google it and get a list of specifiers. One thing I forgot to note:

If you try this:

print "First is: %s" % (first)

It converts the float value in first to a string. So that would work as well.

I know this is not an ideal question to answer but as the OP seems to be a beginner, I'd love to share some basic knowledge with him... Hope everybody understands

OP, you can convert a string to type Boolean by using any of the methods stated below:

 string sample = "True";
 bool myBool = bool.Parse(sample);

 ///or

 bool myBool = Convert.ToBoolean(sample);

bool.Parse expects one parameter which in this case is sample, .ToBoolean also expects one parameter.

You can use TryParse which is the same as Parse but it doesn't throw any exception :)

  string sample = "false";
  Boolean myBool;

  if (Boolean.TryParse(sample , out myBool))
  {
  }

Please note that you cannot convert any type of string to type Boolean because the value of a Boolean can only be True or False

Hope you understand :)

Say P7 is a Cell then you can use the following Syntex to check the value of the cell and assign appropriate value to another cell based on this following nested if:

=IF(P7=0,200,IF(P7=1,100,IF(P7=2,25,IF(P7=3,10,IF((P7=4),5,0)))))

Type the kill -l command on your shell

you will found that at 9th number [ 9) SIGKILL ], so one can use either kill -9 or kill -SIGKILL

SIGKILL is sure kill signal, It can not be dis-positioned, ignore or handle. It always work with its default behaviour, which is to kill the process.

I have solved this problem with changing encoding in read.table argument from fileEncoding = "UTF-16" to fileEncoding = "UTF-8".

Find your PHP.ini and look for XDebug.

normally in Ubuntu its path is

/etc/php5/apache2/php.ini  

Make following changes (Better to just comment them by adding ; at the beginning )

xdebug.remote_autostart=0
xdebug.remote_enable=0
xdebug.profiler_enable=0

then restart your server again for Ubuntu

sudo service apache2 restart

Bad request generally means the format of the data you are sending is incorrect. May be mismatched data mapping . If you are getting bad request implies you are able to connect to the server, but the request is not being sent properly.

See this. Your code would be something like the following:

from django.db.models import Max
# Generates a "SELECT MAX..." query
Argument.objects.aggregate(Max('rating')) # {'rating__max': 5}

You can also use this on existing querysets:

from django.db.models import Max
args = Argument.objects.filter(name='foo') # or whatever arbitrary queryset
args.aggregate(Max('rating')) # {'rating__max': 5}

If you need the model instance that contains this max value, then the code you posted is probably the best way to do it:

arg = args.order_by('-rating')[0]

Note that this will error if the queryset is empty, i.e. if no arguments match the query (because the [0] part will raise an IndexError). If you want to avoid that behavior and instead simply return None in that case, use .first():

arg = args.order_by('-rating').first() # may return None

and in jquery:

$('element').attr('some attribute','some attributes value')

i.e

$('a').attr('href','http://www.stackoverflow.com/')

Well, I'm not sure to understand your question...

In C, Char[] and Char* are the same thing.

Edit : thanks for this interesting link.

Though I found Gabriel answer to work to a degree i did find the following when trying to order the list vertically (first ul A-D and second ul E-G):

• When the ul had an even number of li's in it, it was not evenly spreading it across the ul's
• using the data-column in the ul didn't seem to work very well, I had to put 4 for 3 columns and even then it was still only spreading the li's into 2 of the ul generated by the JS

I have revised the JQuery so the above hopefully doesn't happen.

(function ($) {
    var initialContainer = $('.customcolumns'),
        columnItems = $('.customcolumns li'),
        columns = null,
        column = 0;
    function updateColumns() {
        column = 0;
        columnItems.each(function (idx, el) {
            if ($(columns.get(column)).find('li').length >= (columnItems.length / initialContainer.data('columns'))) {
                column += 1;
            }
            $(columns.get(column)).append(el);
        });
    }
    function setupColumns() {
        columnItems.detach();
        while (column++ < initialContainer.data('columns')) {
            initialContainer.clone().insertBefore(initialContainer);
            column++;
        }
        columns = $('.customcolumns');
        updateColumns();
    }

    $(setupColumns);
})(jQuery);

.customcolumns {
  float: left;
  position: relative;
  margin-right: 20px;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

No there isn't and it's probably not there, because there are very few valid uses for it. I would think twice before using it. Also, it is indeed easy to create yourself.

Please refer to this discussion about why it's even in .NET.

I guess UnsupportedOperationException comes close, although it doesn't say the operation is just not implemented, but unsupported even. That could imply no valid implementation is possible. Why would the operation be unsupported? Should it even be there? Interface segregation or Liskov substitution issues maybe?

If it's work in progress I'd go for ToBeImplementedException, but I've never caught myself defining a concrete method and then leave it for so long it makes it into production and there would be a need for such an exception.

I resolved that issue by using a data container, this also has the advantage of isolating the data from the application layer. You could run it like this:

docker run --volumes-from=<container-data-name> ubuntu

This tutorial provides a good explanation on the use of data containers.

I know this is a very old question but I want to add an answer I have come up with.

First you need a handler for your normal TextChanged event handler for the TextBox:

private bool InProg;
internal void TBTextChanged(object sender, TextChangedEventArgs e)
            {
            var change = e.Changes.FirstOrDefault();
            if ( !InProg )
                {
                InProg = true;
                var culture = new CultureInfo(CultureInfo.CurrentCulture.Name);
                var source = ( (TextBox)sender );
                    if ( ( ( change.AddedLength - change.RemovedLength ) > 0 || source.Text.Length > 0 ) && !DelKeyPressed )
                        {
                         if ( Files.Where(x => x.IndexOf(source.Text, StringComparison.CurrentCultureIgnoreCase) == 0 ).Count() > 0 )
                            {
                            var _appendtxt = Files.FirstOrDefault(ap => ( culture.CompareInfo.IndexOf(ap, source.Text, CompareOptions.IgnoreCase) == 0 ));
                            _appendtxt = _appendtxt.Remove(0, change.Offset + 1);
                            source.Text += _appendtxt;
                            source.SelectionStart = change.Offset + 1;
                            source.SelectionLength = source.Text.Length;
                            }
                        }
                InProg = false;
                }
            }

Then make a simple PreviewKeyDown handler:

    private static bool DelKeyPressed;
    internal static void DelPressed(object sender, KeyEventArgs e)
    { if ( e.Key == Key.Back ) { DelKeyPressed = true; } else { DelKeyPressed = false; } }

In this example "Files" is a list of directory names created on application startup.

Then just attach the handlers:

public class YourClass
  {
  public YourClass()
    {
    YourTextbox.PreviewKeyDown += DelPressed;
    YourTextbox.TextChanged += TBTextChanged;
    }
  }

With this whatever you choose to put in the List will be used for the autocomplete box. This may not be a great option if you expect to have an enormous list for the autocomplete but in my app it only ever sees 20-50 items so it cycles through very quick.

here i have explained how the empty function and isset works please use the one that is appropriate also you can use is_null function also

<?php
    $val = 0;
    //evaluates to true because $var is empty
    if (empty($val)) {
        echo '$val is either 0, empty, or not set at all';
    }
    //evaluates to true because $VAR IS SET
    if (isset($val)) {
        echo '$val is set even though it is empty';
    }
    ?>

<div class="row">

  <div class="col-sm-6">
    <div class="card">
        Content one
    </div>
  </div>

  <div class="col-sm-6">
    <div class="card">
        Content two
    </div>
  </div>

</div>

I'll just leave this here for people interested in an implementation with no dependencies.

inline int
stringLength (char *String)
    {
    int Count = 0;
    while (*String ++) ++ Count;
    return Count;
    }

inline int
stringToInt (char *String)
    {
    int Integer = 0;
    int Length = stringLength(String);
    for (int Caret = Length - 1, Digit = 1; Caret >= 0; -- Caret, Digit *= 10)
        {
        if (String[Caret] == '-') return Integer * -1;
        Integer += (String[Caret] - '0') * Digit;
        }

    return Integer;
    }

Works with negative values, but can't handle non-numeric characters mixed in between (should be easy to add though). Integers only.

In HTML, the less-than sign is used at the beginning of tags. if you use this bracket "<test1>" in content, your bracket content will be unvisible, html renderer is assuming it as a html tag, changing chars with it's ASCI numbers prevents the issue.

with html friendly name:

  <test1> 

or with asci number:

 <test1>

or comple asci:

<test1>

result: <test1>

asci referance: https://www.w3schools.com/charsets/ref_html_ascii.asp

DATE_FORMAT(FROM_UNIXTIME(`orderdate`), '%Y-%m-%d %H:%i:%s') as "Date" FROM `orders`

This is the ultimate solution if the given date is in encoded format like 1300464000

My case may not be typical but what I wanted to do was to have certain columns in a TABLE completely "inert": impossible to tab into them, and impossible to select anything in them. I had found class "unselectable" from other SO answers:

.unselectable {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

This actually prevents the user using the mouse to put the focus in the TD ... but I couldn't find a way on SO to prevent tabbing into cells. The TDs in my TABLE actually each has a DIV as their sole child, and using console.log I found that in fact the DIVs would get the focus (without the focus first being obtained by the TDs).

My solution involves keeping track of the "previously focused" element (anywhere on the page):

window.currFocus = document;
//Catch any bubbling focusin events (focus does not bubble)
$(window).on('focusin', function () {
  window.prevFocus = window.currFocus;
  window.currFocus = document.activeElement;
});

I can't really see how you'd get by without a mechanism of this kind... jolly useful for all sorts of purposes ... and of course it'd be simple to transform it into a stack of recently focused elements, if you wanted that...

The simplest answer is then just to do this (to the sole DIV child in every newly created TD):

...
jqNewCellDiv[ 0 ].classList.add( 'unselectable' );
jqNewCellDiv.focus( function() {
    window.prevFocus.focus();
});         

So far so good. It should be clear that this would work if you just have a TD (with no DIV child). Slight issue: this just stops tabbing dead in its tracks. Clearly if the table has any more cells on that row or rows below the most obvious action you'd want is to making tabbing tab to the next non-unselectable cell ... either on the same row or, if there are other rows, on the row below. If it's the very end of the table it gets a bit more tricky: i.e. where should tabbing go then. But all good clean fun.

Try to use toISOString(). It returns string in ISO8601 format.

GET method

javascript

$.get('/example/doGet?date=' + new Date().toISOString(), function (result) {
    console.log(result);
});

c#

[HttpGet]
public JsonResult DoGet(DateTime date)
{
    return Json(date.ToString(), JsonRequestBehavior.AllowGet);
}

POST method

javascript

$.post('/example/do', { date: date.toISOString() }, function (result) {
    console.log(result);
});

c#

[HttpPost]
public JsonResult Do(DateTime date)
{
     return Json(date.ToString());
}

I made it work by doing the following:

• Delete the ".vs" folder under the application folder
• Delete the "IISExpress" folder from the Document
• Enable the 64 bit version of IIS Express on visual studio by going to Tools -> Options -> Projects and Solutions -> Web Projects
• May need to delete everything from temp folder
• May need to change the port by right click on project, go to properties, under web and change the project url port.

You need a semicolon after font-family: Arial, Helvetica, sans-serif. This will make your updated code the following:

<!DOCTYPE>
<html>
    <head>
        <title>DIV Font</title>

        <style>
            .my_text
            {
                font-family:    Arial, Helvetica, sans-serif;
                font-size:      40px;
                font-weight:    bold;
            }
        </style>
    </head>

    <body>
        <div class="my_text">some text</div>
    </body>
</html>

Rather than using sub queries in where condition which will increase the query time where records are huge.

I would suggest to use Inner Join as a better option to this problem.

Considering the same table this could give the result

SELECT EmailAddress, CustomerName FROM Customers as a 
Inner Join Customers as b on a.CustomerName <> b.CustomerName and a.EmailAddress = b.EmailAddress

For still better results I would suggest you to use CustomerID or any unique field of your table. Duplication of CustomerName is possible.

Most likely you should use CopyWebpackPlugin which was mentioned in kevlened answer. Alternativly for some kind of files like .html or .json you can also use raw-loader or json-loader. Install it via npm install -D raw-loader and then what you only need to do is to add another loader to our webpack.config.js file.

Like:

{
    test: /\.html/,
    loader: 'raw'
}

Note: Restart the webpack-dev-server for any config changes to take effect.

And now you can require html files using relative paths, this makes it much easier to move folders around.

template: require('./nav.html')  

If you are using Sql Server 2005 you can use table valued functions. You can call these directly and pass paramters, whilst treating them as if they were tables.

For more info check out Table-Valued User-Defined Functions

public string RemoveCharactersBeforeDot(string s)
{
 string splitted=s.Split('.');
 return splitted[splitted.Length-1]
}

Here is specifically what worked for me only when the Excel file being queried was not open and when running the SQL Server Service as me [as a user that has access to the file system]. I see pieces of my answer already given elsewhere, so I apologize for any redundancy, but for the sake of a more succinct answer:

You can just use a list comprehension:

my_list = [1, 2, 3, 4, 5]
my_new_list = [i * 5 for i in my_list]

>>> print(my_new_list)
[5, 10, 15, 20, 25]

Note that a list comprehension is generally a more efficient way to do a for loop:

my_new_list = []
for i in my_list:
    my_new_list.append(i * 5)

>>> print(my_new_list)
[5, 10, 15, 20, 25]

As an alternative, here is a solution using the popular Pandas package:

import pandas as pd

s = pd.Series(my_list)

>>> s * 5
0     5
1    10
2    15
3    20
4    25
dtype: int64

Or, if you just want the list:

>>> (s * 5).tolist()
[5, 10, 15, 20, 25]

FileInputStream is an inputStream.

FileInputStream fis = new FileInputStream("c://filename");
InputStream is = fis;
fis.close();  
return is;

Of course, this will not do what you want it to do; the stream you return has already been closed. Just return the FileInputStream and be done with it. The calling code should close it.

You can change the passwd file directly for the particular user or use the below command

chsh -s /usr/local/bin/bash username

Then log out and log in

With Rails 4 it's easy:

 Foo.includes(:bar).where.not(bars: {id: nil})

See also: http://guides.rubyonrails.org/active_record_querying.html#not-conditions

I dont know if this is still useful. I achieved something like this with a java library at http://www.pushlets.com/

Althoug doing it in a service won't prevent android from shutting it down an killing the listener thread.

I want to indent a specific section of code in Visual Studio Code:

• Select the lines you want to indent, and
• use Ctrl + ] to indent them.

If you want to format a section (instead of indent it):

• Select the lines you want to format,
• use Ctrl + K, Ctrl + F to format them.

Typically we would place one of these at or near the top of the script. Scripts that parse their command lines would do the redirection after parsing.

Send stdout to a file

exec > file

with stderr

exec > file                                                                      
exec 2>&1

append both stdout and stderr to file

exec >> file
exec 2>&1

As Jonathan Leffler mentioned in his comment:

exec has two separate jobs. The first one is to replace the currently executing shell (script) with a new program. The other is changing the I/O redirections in the current shell. This is distinguished by having no argument to exec.

C# has a static constructor for this purpose.

static class YourClass
{
    static YourClass()
    {
        // perform initialization here
    }
}

From MSDN:

A static constructor is used to initialize any static data, or to perform a particular action that needs to be performed once only. It is called automatically before the first instance is created or any static members are referenced

Chrome doesn't allow you to integrate two different localhost,that's why we are getting this error. You just have to include Microsoft Visual Studio Web Api Core package from nuget manager.And add the two lines of code in WebApi project's in your WebApiConfig.cs file.

var cors = new EnableCorsAttribute("*", "*", "*");
config.EnableCors(cors);

Then all done.

Add this to build.gradle file

dexOptions {
   javaMaxHeapSize "2g"
}

No, Mockito does not support this.

This might not be the answer you're looking for, but what you're seeing is a symptom of not applying the design principle:

Favor composition over inheritance

If you extract a strategy instead of extending a super class the problem is gone.

If however you are not allowed to change the code, but you must test it anyway, and in this awkward way, there is still hope. With some AOP tools (for example AspectJ) you can weave code into the super class method and avoid its execution entirely (yuck). This doesn't work if you're using proxies, you have to use bytecode modification (either load time weaving or compile time weaving). There are be mocking frameworks that support this type of trick as well, like PowerMock and PowerMockito.

I suggest you go for the refactoring, but if that is not an option you're in for some serious hacking fun.

DataRow's are nice in the way that they have their underlying table linked to them. With the underlying table you can verify that a specific row has a specific column in it.

    If DataRow.Table.Columns.Contains("column") Then
        MsgBox("YAY")
    End If

window.getSelection - vs - document.selection

This one works for me:

function getCaretCharOffset(element) {_x000D_
  var caretOffset = 0;_x000D_
_x000D_
  if (window.getSelection) {_x000D_
    var range = window.getSelection().getRangeAt(0);_x000D_
    var preCaretRange = range.cloneRange();_x000D_
    preCaretRange.selectNodeContents(element);_x000D_
    preCaretRange.setEnd(range.endContainer, range.endOffset);_x000D_
    caretOffset = preCaretRange.toString().length;_x000D_
  } _x000D_
_x000D_
  else if (document.selection && document.selection.type != "Control") {_x000D_
    var textRange = document.selection.createRange();_x000D_
    var preCaretTextRange = document.body.createTextRange();_x000D_
    preCaretTextRange.moveToElementText(element);_x000D_
    preCaretTextRange.setEndPoint("EndToEnd", textRange);_x000D_
    caretOffset = preCaretTextRange.text.length;_x000D_
  }_x000D_
_x000D_
  return caretOffset;_x000D_
}_x000D_
_x000D_
_x000D_
// Demo:_x000D_
var elm = document.querySelector('[contenteditable]');_x000D_
elm.addEventListener('click', printCaretPosition)_x000D_
elm.addEventListener('keydown', printCaretPosition)_x000D_
_x000D_
function printCaretPosition(){_x000D_
  console.log( getCaretCharOffset(elm), 'length:', this.textContent.trim().length )_x000D_
}

<div contenteditable>some text here <i>italic text here</i> some other text here <b>bold text here</b> end of text</div>

The calling line depends on event type, for key event use this:

getCaretCharOffsetInDiv(e.target) + ($(window.getSelection().getRangeAt(0).startContainer.parentNode).index());

for mouse event use this:

getCaretCharOffsetInDiv(e.target.parentElement) + ($(e.target).index())

on these two cases I take care for break lines by adding the target index

Collection initializers are only available in VB.NET 2010, released 2010-04-12:

Dim theVar = New List(Of String) From { "one", "two", "three" }

If you format the string and return object like RestApiResponse<String>, you'll get unwanted characters like escaping etc: \n, \". Solution is to convert your JSON-string into Jackson JsonNode object and return RestApiResponse<JsonNode>:

ObjectMapper mapper = new ObjectMapper();
JsonNode tree = objectMapper.readTree(jsonString);
RestApiResponse<JsonNode> response = new RestApiResponse<>();
apiResponse.setData(tree);
return response;

@Eevee: As the browser becomes the home for richer and richer functionality and starts to replace desktop apps, it's just not going to be an option to forgo the use of keyboard shortcuts. Gmail's rich and intuitive set of keyboard commands was instrumental in my willingness to abandon Outlook. The keyboard shortcuts in Todoist, Google Reader, and Google Calendar all make my life much, much easier on a daily basis.

Developers should definitely be careful not to override keystrokes that already have a meaning in the browser. For example, the WMD textbox I'm typing into inexplicably interprets Ctrl+Del as "Blockquote" rather than "delete word forward". I'm curious if there's a standard list somewhere of "browser-safe" shortcuts that site developers can use and that browsers will commit to staying away from in future versions.

This is a complete procedure to transfer database and logins from an istance to a new one, scripting logins and relocating datafile and log files on the destination. Everything using metascripts.

http://zaboilab.com/sql-server-toolbox/massive-database-migration-between-sql-server-instances-the-complete-procedure

Sorry for the off-site procedure but scripts are very long. You have to:
- Script logins with original SID and HASHED password
- Create script to backup database using metascripts
- Create script to restore database passing relocate parameters using again metascripts
- Run the generated scripts on source and destination instance.
See details and download scripts following the link above.

Thx for the answer!

raiserror() works fine but you shouldn't forget the return statement otherwise the script continues without error! (hense the raiserror isn't a "throwerror" ;-)) and of course doing a rollback if necessary!

raiserror() is nice to tell the person who executes the script that something went wrong.

Just use the == with the negation symbol (!). If dtfm is the name of your data.frame:

dtfm[!dtfm$C == "Foo", ]

Or, to move the negation in the comparison:

dtfm[dtfm$C != "Foo", ]

Or, even shorter using subset():

subset(dtfm, C!="Foo")

None of the answers will solve your problem permanently. If you go to the path of adding XSD (From Xml menu, select "Create schema"), you will end up having problems with the package manager as it will clean up your packages.config file when you add a new package.

The best solution is just ignore by closing the file when you don't use it.

WARNING: There is a significant performance penalty with the live version of hover. It's especially noticeable in a large page on IE8.

I am working on a project where we load multi-level menus with AJAX (we have our reasons :). Anyway, I used the live method for the hover which worked great on Chrome (IE9 did OK, but not great). However, in IE8 It not only slowed down the menus (you had to hover for a couple seconds before it would drop), but everything on the page was painfully slow, including scrolling and even checking simple checkboxes.

Binding the events directly after they loaded resulted in adequate performance.

I found the reason why there is always a white boder of the background image, if I put the image in a 'div' element inside 'body'. But the image can be full screen, if I put it as background image of 'body'.

Because the default 'margin' of 'body' is not zero. After add this css, the background image can be full screen even I put it in 'div'.

body {
    margin: 0px;
}

You can use a Handler to post runnable code. This technique is outlined very nicely here: https://guides.codepath.com/android/Repeating-Periodic-Tasks

I guess you want to do the "Iterating over Keys and Values"

As the doc here says, just add "|keys" in the variable you want and it will magically happen.

{% for key, user in users %}
    <li>{{ key }}: {{ user.username|e }}</li>
{% endfor %}

It never hurts to search before asking :)

Try: Controls("Check Box 1") = True

For me this happened because i merged a branch dev into master using web interface and then tried to sync/pull using VSCode which was open on dev branch.(its weird that i could not change to master without getting this error.)

git pull
Your configuration specifies to merge with the ref 'refs/heads/dev'
from the remote, but no such ref was fetched.'

It makes sense that is not finding it refs/heads/dev - for me it was easier to just delete the local folder and clone again.

You asked of Function but there is an easier way too. When you will upload the image, copy it's URL which is at the top right part of the window (View Screenshot) and paste it in the src='[link you copied]'. Hope this will help if someone is looking for similar problem.

The 'u' in front of the string values means the string is a Unicode string. Unicode is a way to represent more characters than normal ASCII can manage. The fact that you're seeing the u means you're on Python 2 - strings are Unicode by default on Python 3, but on Python 2, the u in front distinguishes Unicode strings. The rest of this answer will focus on Python 2.

You can create a Unicode string multiple ways:

>>> u'foo'
u'foo'
>>> unicode('foo') # Python 2 only
u'foo'

But the real reason is to represent something like this (translation here):

>>> val = u'???????????? ? ?????????????'
>>> val
u'\u041e\u0437\u043d\u0430\u043a\u043e\u043c\u044c\u0442\u0435\u0441\u044c \u0441 \u0434\u043e\u043a\u0443\u043c\u0435\u043d\u0442\u0430\u0446\u0438\u0435\u0439'
>>> print val
???????????? ? ?????????????

For the most part, Unicode and non-Unicode strings are interoperable on Python 2.

There are other symbols you will see, such as the "raw" symbol r for telling a string not to interpret backslashes. This is extremely useful for writing regular expressions.

>>> 'foo\"'
'foo"'
>>> r'foo\"'
'foo\\"'

Unicode and non-Unicode strings can be equal on Python 2:

>>> bird1 = unicode('unladen swallow')
>>> bird2 = 'unladen swallow'
>>> bird1 == bird2
True

but not on Python 3:

>>> x = u'asdf' # Python 3
>>> y = b'asdf' # b indicates bytestring
>>> x == y
False

You can do it easily by using JUnit or TestNG framework. Do the assertion as below:

String actualTitle = driver.getTitle();
String expectedTitle = "Title of Page";
assertEquals(expectedTitle,actualTitle);

OR,

assertTrue(driver.getTitle().contains("Title of Page"));

The ZT Process Executor library is an alternative to Apache Commons Exec. It has functionality to run commands, capturing their output, setting timeouts, etc.

I have not used it yet, but it looks reasonably well-documented.

An example from the documentation: Executing a command, pumping the stderr to a logger, returning the output as UTF8 string.

 String output = new ProcessExecutor().command("java", "-version")
    .redirectError(Slf4jStream.of(getClass()).asInfo())
    .readOutput(true).execute()
    .outputUTF8();

Its documentation lists the following advantages over Commons Exec:

• Improved handling of streams
  • Reading/writing to streams
  • Redirecting stderr to stdout
• Improved handling of timeouts
• Improved checking of exit codes
• Improved API
  • One liners for quite complex use cases
  • One liners to get process output into a String
  • Access to the Process object available
  • Support for async processes ( Future )
• Improved logging with SLF4J API
• Support for multiple processes

on tomcat v.7 (vanilla installation)

in your conf/server.xml add the following bit towards the end of the file, just before the </Host> closing tag:

<Context path="" docBase="app_name">
    <!-- Default set of monitored resources -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>

Note that docBase attribute. It's the important bit. You either make sure you've deployed app_name before you change your root web app, or just copy your unpacked webapp (app_name) into your tomcat's webapps folder. Startup, visit root, see your app_name there!

I no longer work on Android project for a while. Although the below provides some clue to how an android studio project can be configured, but I can't guarantee it works flawlessly.

In principle, IntelliJ respects the build file and will try to use it to configure the IDE project. It's not true in the other way round, IDE changes normally will not affect the build file.

Since most Android projects are built by Gradle, it's always a good idea to understand this tool.

I'd suggest referring to @skyfishjy's answer, as it seems to be more updated than this one.

The below is not updated

Although android studio is based on IntelliJ IDEA, at the same time it relies on gradle to build your apk. As of 0.2.3, these two doesn't play nicely in term of configuring from GUI. As a result, in addition to use the GUI to setup dependencies, it will also require you to edit the build.gradle file manually.

Assuming you have a Test Project > Test structure. The build.gradle file you're looking for is located at TestProject/Test/build.gradle

Look for the dependencies section, and make sure you have

compile 'com.android.support:support-v4:13.0.+'

Below is an example.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.android.support:support-v4:13.0.+'
}

android {
    compileSdkVersion 18
    buildToolsVersion "18.0.1"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 16
    }
}

You can also add 3rd party libraries from the maven repository

compile group: 'com.google.code.gson', name: 'gson', version: '2.2.4'

The above snippet will add gson 2.2.4 for you.

In my experiment, it seems that adding the gradle will also setup correct IntelliJ dependencies for you.

Just found that issue corresponding to my problem. Using HandlerMapping constants I was able to wrote a small utility for that purpose:

/**
 * Extract path from a controller mapping. /controllerUrl/** => return matched **
 * @param request incoming request.
 * @return extracted path
 */
public static String extractPathFromPattern(final HttpServletRequest request){


    String path = (String) request.getAttribute(
            HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
    String bestMatchPattern = (String ) request.getAttribute(HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE);

    AntPathMatcher apm = new AntPathMatcher();
    String finalPath = apm.extractPathWithinPattern(bestMatchPattern, path);

    return finalPath;

}

I have found an elegant solution that would cover most of your bases. I wrote about it initially here and answered another similar StackOverflow question here which references it.

FYI this solution also includes hardcoded fallback tags in case Javascript isn't picked up by the crawler. I haven't explicitly outlined it, but it is worth mentioning that you should be activating HTML5 mode for proper URL support.

Also note: these aren't the complete files, just the important parts of those that are relevant. If you need help writing the boilerplate for directives, services, etc. that can be found elsewhere. Anyway, here goes...

app.js

This is where you provide the custom metadata for each of your routes (title, description, etc.)

$routeProvider
   .when('/', {
       templateUrl: 'views/homepage.html',
       controller: 'HomepageCtrl',
       metadata: {
           title: 'The Base Page Title',
           description: 'The Base Page Description' }
   })
   .when('/about', {
       templateUrl: 'views/about.html',
       controller: 'AboutCtrl',
       metadata: {
           title: 'The About Page Title',
           description: 'The About Page Description' }
   })

metadata-service.js (service)

Sets the custom metadata options or use defaults as fallbacks.

var self = this;

// Set custom options or use provided fallback (default) options
self.loadMetadata = function(metadata) {
  self.title = document.title = metadata.title || 'Fallback Title';
  self.description = metadata.description || 'Fallback Description';
  self.url = metadata.url || $location.absUrl();
  self.image = metadata.image || 'fallbackimage.jpg';
  self.ogpType = metadata.ogpType || 'website';
  self.twitterCard = metadata.twitterCard || 'summary_large_image';
  self.twitterSite = metadata.twitterSite || '@fallback_handle';
};

// Route change handler, sets the route's defined metadata
$rootScope.$on('$routeChangeSuccess', function (event, newRoute) {
  self.loadMetadata(newRoute.metadata);
});

metaproperty.js (directive)

Packages the metadata service results for the view.

return {
  restrict: 'A',
  scope: {
    metaproperty: '@'
  },
  link: function postLink(scope, element, attrs) {
    scope.default = element.attr('content');
    scope.metadata = metadataService;

    // Watch for metadata changes and set content
    scope.$watch('metadata', function (newVal, oldVal) {
      setContent(newVal);
    }, true);

    // Set the content attribute with new metadataService value or back to the default
    function setContent(metadata) {
      var content = metadata[scope.metaproperty] || scope.default;
      element.attr('content', content);
    }

    setContent(scope.metadata);
  }
};

index.html

Complete with the hardcoded fallback tags mentioned earlier, for crawlers that can't pick up any Javascript.

<head>
  <title>Fallback Title</title>
  <meta name="description" metaproperty="description" content="Fallback Description">

  <!-- Open Graph Protocol Tags -->
  <meta property="og:url" content="fallbackurl.com" metaproperty="url">
  <meta property="og:title" content="Fallback Title" metaproperty="title">
  <meta property="og:description" content="Fallback Description" metaproperty="description">
  <meta property="og:type" content="website" metaproperty="ogpType">
  <meta property="og:image" content="fallbackimage.jpg" metaproperty="image">

  <!-- Twitter Card Tags -->
  <meta name="twitter:card" content="summary_large_image" metaproperty="twitterCard">
  <meta name="twitter:title" content="Fallback Title" metaproperty="title">
  <meta name="twitter:description" content="Fallback Description" metaproperty="description">
  <meta name="twitter:site" content="@fallback_handle" metaproperty="twitterSite">
  <meta name="twitter:image:src" content="fallbackimage.jpg" metaproperty="image">
</head>

This should help dramatically with most search engine use cases. If you want fully dynamic rendering for social network crawlers (which are iffy on Javascript support), you'll still have to use one of the pre-rendering services mentioned in some of the other answers.

Hope this helps!

I found this question when looking for a way to really read a local file instead of reading a file from the web server, which I'd rather call a "remote file".

Just call require:

const content = require('../../path_of_your.json');

The Angular-CLI source code inspired me: I found out that they include component templates by replacing the templateUrl property by template and the value by a require call to the actual HTML resource.

If you use the AOT compiler you have to add the node type definitons by adjusting tsconfig.app.json:

"compilerOptions": {
  "types": ["node"],
  ...
},
...

In Winform App(C#):

static string strFilesLoc = Path.GetFullPath(Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), @"..\..\")) + "Resources\\";

1. If you want the password prompt to go away then use key based authentication (described here).

2. To run commands remotely over ssh you have to give them as an argument to ssh, like the following:

root@host:~ # ssh root@www 'ps -ef | grep apache | grep -v grep | wc -l'

For mysql 8.0.19, I finally found the my.cnf here: /usr/local/opt/mysql/.bottle/etc I copied it to /usr/local/opt/mysql/ and modified it. Then I restart the mysql service, it works.

You should explicitly specify the second parameter (sheetname) as None. like this:

 df = pandas.read_excel("/yourPath/FileName.xlsx", None);

"df" are all sheets as a dictionary of DataFrames, you can verify it by run this:

df.keys()

result like this:

[u'201610', u'201601', u'201701', u'201702', u'201703', u'201704', u'201705', u'201706', u'201612', u'fund', u'201603', u'201602', u'201605', u'201607', u'201606', u'201608', u'201512', u'201611', u'201604']

please refer pandas doc for more details: https://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_excel.html

In ef core, you can change the migration that was created after add migration. And then do update-database. A sample has given below:

protected override void Up(MigrationBuilder migrationBuilder)
{
    migrationBuilder.RenameColumn(name: "Type", table: "Users", newName: "Discriminator", schema: "dbo");
}

protected override void Down(MigrationBuilder migrationBuilder)
{            
    migrationBuilder.RenameColumn(name: "Discriminator", table: "Users", newName: "Type", schema: "dbo");
}

Instead of "right click"....start your session (once you're in the command prompt window) by keying Alt/SpaceBar. That will open the Command Prompt window menu and you'll see your familiar, underlined keyboard command shortcuts, just like in Windows GUI.

Good luck!

Even though you are not using areas, you can still specify in your RouteMap which namespace to use

routes.MapRoute(
    "Default",
    "{controller}/{action}",
    new { controller = "Home", action = "Index" },
    new[] { "NameSpace.OfYour.Controllers" }
);

But it sounds like the actual issue is the way your two apps are set up in IIS

For whatever reason $('.panel-collapse').collapse({'toggle': true, 'parent': '#accordion'}); only seems to work the first time and it only works to expand the collapsible. (I tried to start with a expanded collapsible and it wouldn't collapse.)

It could just be something that runs once the first time you initialize collapse with those parameters.

You will have more luck using the show and hide methods.

Here is an example:

$(function() {

  var $active = true;

  $('.panel-title > a').click(function(e) {
    e.preventDefault();
  });

  $('.collapse-init').on('click', function() {
    if(!$active) {
      $active = true;
      $('.panel-title > a').attr('data-toggle', 'collapse');
      $('.panel-collapse').collapse('hide');
      $(this).html('Click to disable accordion behavior');
    } else {
      $active = false;
      $('.panel-collapse').collapse('show');
      $('.panel-title > a').attr('data-toggle','');
      $(this).html('Click to enable accordion behavior');
    }
  });

});

Update

Granted KyleMit seems to have a way better handle on this then me. I'm impressed with his answer and understanding.

I don't understand what's going on or why the show seemed to be toggling in some places.

But After messing around for a while.. Finally came with the following solution:

$(function() {
  var transition = false;
  var $active = true;

  $('.panel-title > a').click(function(e) {
    e.preventDefault();
  });

  $('#accordion').on('show.bs.collapse',function(){
    if($active){
        $('#accordion .in').collapse('hide');
    }
  });

  $('#accordion').on('hidden.bs.collapse',function(){
    if(transition){
        transition = false;
        $('.panel-collapse').collapse('show');
    }
  });

  $('.collapse-init').on('click', function() {
    $('.collapse-init').prop('disabled','true');
    if(!$active) {
      $active = true;
      $('.panel-title > a').attr('data-toggle', 'collapse');
      $('.panel-collapse').collapse('hide');
      $(this).html('Click to disable accordion behavior');
    } else {
      $active = false;
      if($('.panel-collapse.in').length){
        transition = true;
        $('.panel-collapse.in').collapse('hide');       
      }
      else{
        $('.panel-collapse').collapse('show');
      }
      $('.panel-title > a').attr('data-toggle','');
      $(this).html('Click to enable accordion behavior');
    }
    setTimeout(function(){
        $('.collapse-init').prop('disabled','');
    },800);
  });
});

http://www.eclipse.org/cdt/ ^Give that a try

I have not used the CDT for eclipse but I do use Eclipse Java for Ubuntu 12.04 and it works wonders.

imread is depreciated after version 1.2.0! So to solve this issue I had to install version 1.1.0.

pip install scipy==1.1.0

As of (dplyr 1.0.0) we can use across()

For all columns:

dat <- dat %>%
   mutate(across(everything(), ~ifelse(.=="", NA, as.character(.))))

For individual columns:

dat <- dat %>%
   mutate(across(c("Age","Gender"), ~ifelse(.=="", NA, as.character(.))))

As of (dplyr 0.8.0 above) the way this should be written has changed. Before it was, funs() in .funs (funs(name = f(.)). Instead of funs, now we use list (list(name = ~f(.)))

Note that there is also a much simpler way to list the column names ! (both the name of the column and column index work)

dat <- dat %>%
mutate_at(.vars = c("Age","Gender"),
    .funs = list(~ifelse(.=="", NA, as.character(.))))

Original Answer:

You can also use mutate_at in dplyr

dat <- dat %>%
mutate_at(vars(colnames(.)),
        .funs = funs(ifelse(.=="", NA, as.character(.))))

Select individual columns to change:

dat <- dat %>%
mutate_at(vars(colnames(.)[names(.) %in% c("Age","Gender")]),
        .funs = funs(ifelse(.=="", NA, as.character(.))))

Here is an alternative that worked for me:

$('div#somediv').css({'width': '70%'});

The solution I opted for was to format the date with the mysql query :

String l_mysqlQuery = "SELECT DATE_FORMAT(time, '%Y-%m-%d %H:%i:%s') FROM uld_departure;"
l_importedTable = fStatement.executeQuery( l_mysqlQuery );
System.out.println(l_importedTable.getString( timeIndex));

I had the exact same issue. Even though my mysql table contains dates formatted as such : 2017-01-01 21:02:50

String l_mysqlQuery = "SELECT time FROM uld_departure;"
l_importedTable = fStatement.executeQuery( l_mysqlQuery );
System.out.println(l_importedTable.getString( timeIndex));

was returning a date formatted as such : 2017-01-01 21:02:50.0

I don't think such a thing is possible. You can use SUBSTRING function to extract the part you want.

Call clear() method from your custom adapter .

python: read lines from compressed text files

Using gzip.GzipFile:

import gzip

with gzip.open('input.gz','r') as fin:        
    for line in fin:        
        print('got line', line)

Simply add an extension to the -i flag. This basically creates a backup file with the original file.

sed -i.bakup 's/linenumber/number/' ~/.vimrc

sed will execute without the error

I've used the implementation above and just now I came to know that it doesn't work on iPad running iOS 13. I had to add these lines before present() call in order to make it work

//avoiding to crash on iPad
if let popoverController = activityViewController.popoverPresentationController {
     popoverController.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
     popoverController.sourceView = self.view
     popoverController.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
}

That's how it works for me

func shareData(_ dataToShare: [Any]){

        let activityViewController = UIActivityViewController(activityItems: dataToShare, applicationActivities: nil)

        //exclude some activity types from the list (optional)
        //activityViewController.excludedActivityTypes = [
            //UIActivity.ActivityType.postToFacebook
        //]

        //avoiding to crash on iPad
        if let popoverController = activityViewController.popoverPresentationController {
            popoverController.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
            popoverController.sourceView = self.view
            popoverController.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
        }

        self.present(activityViewController, animated: true, completion: nil)
    }

Give zero to mindate and it'll disabale past dates.

$( "#datepicker" ).datepicker({ minDate: 0});

here is a Live fiddle working example http://jsfiddle.net/mayooresan/ZL2Bc/

The official documentation is available here

Use \t and enclose the string with double-quotes:

$chunk = "abc\tdef\tghi";

for /r %%v in (*.xls) do ssconvert "%%v" "%%vx"

a couple have people have asked me to explain this, so:

Part 1: for /r %%v in (*.xls)

This part returns an array of files in the current directory that have the xls extension. The %% may look a little curious. This is basically the special % character from command line as used in %PATH% or %TEMP%. To use it in a batch file we need to escape it like so: %%PATH%% or %%TEMP%%. In this case we are simply escaping the temporary variable v, which will hold our array of filenames.

We are using the /r switch to search for files recursively, so any matching files in child folders will also be located.

Part 2: do ssconvert "%%v" "%%vx"

This second part is what will get executed once per matching filename, so if the following files were present in the current folder:

c:\temp\mySheet.xls, c:\temp\mySheet_yesterday.xls, c:\temp\mySheet_20160902.xls

the following commands would be executed:

ssconvert "c:\temp\mySheet.xls" "c:\temp\mySheet.xlsx" ssconvert "c:\temp\mySheet_yesterday.xls" "c:\temp\mySheet_yesterday.xlsx" ssconvert "c:\temp\mySheet_20160902.xls" "c:\temp\mySheet_20160902.xlsx"

Boostrap 3 has a component for exactly this. It's:

<span class="badge">100</span>

If anyone else is on this question, when using include('somepath.php'); and that file contains a function, the var must be declared there as well. The inclusion of $var=$var; won't always work. Try running these:

one.php:

<?php
    $vars = array('stack','exchange','.com');

    include('two.php'); /*----- "paste" contents of two.php */

    testFunction(); /*----- execute imported function */
?>

two.php:

<?php
    function testFunction(){ 
        global $vars; /*----- vars declared inside func! */
        echo $vars[0].$vars[1].$vars[2];
    }
?>

I don't know why, but for some reason, the "/bin/bash" version didn't work for me. Instead, the simpler version worked, following the example given here at Oracle Docs.

String[] args = new String[] {"ping", "www.google.com"};
Process proc = new ProcessBuilder(args).start();
