Implement Login for Devices

Facebook Login for Devices is for devices that directly make HTTP calls over the internet. The following are the API calls and responses your device can make.

1. Enable Login for Devices

Change Settings > Advanced > OAuth Settings > Login from Devices to 'Yes'.

2. Generate a Code which is required for facebook device identification

When the person clicks Log in with Facebook, you device should make an HTTP POST to:

POST https://graph.facebook.com/oauth/device?
       type=device_code
       &amp;client_id=<YOUR_APP_ID>
       &amp;scope=<COMMA_SEPARATED_PERMISSION_NAMES> // e.g.public_profile,user_likes

The response comes in this form:

{
  "code": "92a2b2e351f2b0b3503b2de251132f47",
  "user_code": "A1NWZ9",
  "verification_uri": "https://www.facebook.com/device",
  "expires_in": 420,
  "interval": 5
}

This response means:

• Display the string “A1NWZ9” on your device
• Tell the person to go to “facebook.com/device” and enter this code
• The code expires in 420 seconds. You should cancel the login flow after that time if you do not receive an access token
• Your device should poll the Device Login API every 5 seconds to see if the authorization has been successful

3. Display the Code

Your device should display the user_code and tell people to visit the verification_uri such as facebook.com/device on their PC or smartphone. See the Design Guidelines.

4. Poll for Authorization

Your device should poll the Device Login API to see if the person successfully authorized your application. You should do this at the interval in the response to your call in Step 1, which is every 5 seconds. Your device should poll to:

POST https://graph.facebook.com/oauth/device?
       type=device_token
       &amp;client_id=<YOUR_APP_ID> 
       &amp;code=<LONG_CODE_FROM_STEP_1> //e.g."92a2b2e351f2b0b3503b2de251132f47"

You will get 200 HTTP code i.e User has successfully authorized the device. The device can now use the access_token value to make authenticated API calls.

5. Confirm Successful Login

Your device should display their name and if available, a profile picture until they click Continue. To get the person's name and profile picture, your device should make a standard Graph API call:

GET https://graph.facebook.com/v2.3/me?
      fields=name,picture&
      access_token=<USER_ACCESS_TOKEN>

Response:

{
  "name": "John Doe", 
  "picture": {
    "data": {
      "is_silhouette": false, 
      "url": "https://fbcdn.akamaihd.net/hmac...ile.jpg"
    }
  }, 
  "id": "2023462875238472"
}

6. Store Access Tokens

Your device should persist the access token to make other requests to the Graph API.

Device Login access tokens may be valid for up to 60 days but may be invalided in a number of scenarios. For example when a person changes their Facebook password their access token is invalidated.

If the token is invalid, your device should delete the token from its memory. The person using your device needs to perform the Device Login flow again from Step 1 to retrieve a new, valid token.

Top can be compiled from sources or downloaded from sunfreeware.com. As previously posted, vmstat is available (I believe it's in the core install?).

This is a quite confusing way of using Apache configuration directives.

Technically, the first bit is equivalent to

Allow From All

This is because Order Deny,Allow makes the Deny directive evaluated before the Allow Directives. In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.

Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.

The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.

Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.

It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.

The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):

#
# The following lines prevent .htaccess and .htpasswd files from being 
# viewed by Web clients. 
#
<Files ~ "^\.ht">
    Order allow,deny
    Deny from all
    Satisfy all
</Files>

which forbids access to any file beginning by ".ht".

The equivalent Apache 2.4 configuration should look like:

<Files ~ "^\.ht">
    Require all denied
</Files>

Example (junit version- 4.13)

import static org.assertj.core.api.Assertions.assertThat;
import org.junit.Test;

public class TestStr {

@Test
public void testThatStringIsContained(){
    String testStr = "hi,i am a test string";
    assertThat(testStr).contains("test");
 }

}

A string to char array is as simple as

String str = "someString"; 
char[] charArray = str.toCharArray();

Can you explain a little more on what you are trying to do?

* Update *

if I am understanding your new comment, you can use a byte array and example is provided.

byte[] bytes = ByteBuffer.allocate(4).putInt(1695609641).array();

for (byte b : bytes) {
   System.out.format("0x%x ", b);
}

With the following output

0x65 0x10 0xf3 0x29

This may be because you havent set noAuth=true in mongodb.conf

# Turn on/off security.  Off is currently the default
noauth = true
#auth = true

After setting this restart the service using

service mongod restart

I have some fresh tests of different methods of prepending. For small arrays (<1000 elems) the leader is for cycle coupled with a push method. For huge arrays, Unshift method becomes the leader.

But this situation is actual only for Chrome browser. In Firefox unshift has an awesome optimization and is faster in all cases.

ES6 spread is 100+ times slower in all browsers.

strtok() stores the pointer in static variable where did you last time left off , so on its 2nd call , when we pass the null , strtok() gets the pointer from the static variable .

If you provide the same string name , it again starts from beginning.

Moreover strtok() is destructive i.e. it make changes to the orignal string. so make sure you always have a copy of orignal one.

One more problem of using strtok() is that as it stores the address in static variables , in multithreaded programming calling strtok() more than once will cause an error. For this use strtok_r().

See numpy.clip:

index = numpy.clip(index, 0, len(my_list) - 1)

Basically, you need to include the Wordpress loop in your search.php template to loop through the search results and show them as part of the template.

Below is a very basic example from The WordPress Theme Search Template and Page Template over at ThemeShaper.

<?php
/**
 * The template for displaying Search Results pages.
 *
 * @package Shape
 * @since Shape 1.0
 */

get_header(); ?>

        <section id="primary" class="content-area">
            <div id="content" class="site-content" role="main">

            <?php if ( have_posts() ) : ?>

                <header class="page-header">
                    <h1 class="page-title"><?php printf( __( 'Search Results for: %s', 'shape' ), '<span>' . get_search_query() . '</span>' ); ?></h1>
                </header><!-- .page-header -->

                <?php shape_content_nav( 'nav-above' ); ?>

                <?php /* Start the Loop */ ?>
                <?php while ( have_posts() ) : the_post(); ?>

                    <?php get_template_part( 'content', 'search' ); ?>

                <?php endwhile; ?>

                <?php shape_content_nav( 'nav-below' ); ?>

            <?php else : ?>

                <?php get_template_part( 'no-results', 'search' ); ?>

            <?php endif; ?>

            </div><!-- #content .site-content -->
        </section><!-- #primary .content-area -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

You can just use Tab and Shift+Tab

here's the mozilla proposal

http://www-archive.mozilla.org/js/js-file-object.html

this is implemented with a compilation switch in spidermonkey, and also in adobe's extendscript. Additionally (I think) you get the File object in firefox extensions.

rhino has a (rather rudementary) readFile function https://developer.mozilla.org/en/Rhino_Shell

for more complex file operations in rhino, you can use java.io.File methods.

you won't get any of this stuff in the browser though. For similar functionality in a browser you can use the SQL database functions from HTML5, clientside persistence, cookies, and flash storage objects.

If none of the methods help try checking your system and user environments PATH and PYTHONPATH variables.

I was getting this error due to my PATH variable was pointing to different Python installation (which comes from ArcGIS Desktop).

After removing path to my Python installation from PATH variable and completely removing PYTHONPATH variable, I got it working!

Keep in mind that python command will not be available from command line if you remove it from PATH.

a.is(b)

and to check if they are not equal use

!a.is(b)

as for

$b = $('#a')
....
$('#a')[0] == $b[0] // not always true

maybe class added to the element or removed from it after the first assignment

If you need to set the user header string in the curl request, you can use the -H option to set user agent like:

curl -H "user-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.182 Safari/537.36" http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-request-exactly-same-as-using-chrome

Updated user-agent form newest Chrome at 02-22-2021

Using a proxy tool like Charles Proxy really helps make short work of something like what you are asking. Here is what I do, using this SO page as an example (as of July 2015 using Charles version 3.10):

1. Get Charles Proxy running
2. Make web request using browser
3. Find desired request in Charles Proxy
4. Right click on request in Charles Proxy
5. Select 'Copy cURL Request'

You now have a cURL request you can run in a terminal that will mirror the request your browser made. Here is what my request to this page looked like (with the cookie header removed):

curl -H "Host: stackoverflow.com" -H "Cache-Control: max-age=0" -H "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8" -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.89 Safari/537.36" -H "HTTPS: 1" -H "DNT: 1" -H "Referer: https://www.google.com/" -H "Accept-Language: en-US,en;q=0.8,en-GB;q=0.6,es;q=0.4" -H "If-Modified-Since: Thu, 23 Jul 2015 20:31:28 GMT" --compressed http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-request-exactly-same-as-using-chrome

Given a data setup like this:

The formula in cell D2 and copied down is:

=INDEX($B$2:$B$28,MATCH(1,INDEX(($A$2:$A$28=LARGE($A$2:$A$28,ROWS(D$1:D1)))*(COUNTIF(D$1:D1,$B$2:$B$28)=0),),0))

This formula will work even if there are tied OPS scores among players.

Model

Very basic model with Gender field. GetGenderSelectItems() returns select items needed to populate DropDownList.

public enum Gender 
{
    Male, Female
}

public class MyModel
{
    public Gender Gender { get; set; }

    public static IEnumerable<SelectListItem> GetGenderSelectItems()
    {
        yield return new SelectListItem { Text = "Male", Value = "Male" };
        yield return new SelectListItem { Text = "Female", Value = "Female" };
    }
}

View

Please make sure you wrapped your @Html.DropDownListFor in a form tag.

@model MyModel

@using (Html.BeginForm("MyController", "MyAction", FormMethod.Post)
{
   @Html.DropDownListFor(m => m.Gender, MyModel.GetGenderSelectItems())
   <input type="submit" value="Send" />
}

Controller

Your .cshtml Razor view name should be the same as controller action name and folder name should match controller name e.g Views\MyController\MyAction.cshtml.

public class MyController : Controller 
{
    public ActionResult MyAction()
    {
        // shows your form when you load the page
        return View();
    }

    [HttpPost]
    public ActionResult MyAction(MyModel model)
    {
        // the value is received in the controller.
        var selectedGender = model.Gender;
        return View(model);
    }
}

Going further

Now let's make it strongly-typed and enum independent:

var genderSelectItems = Enum.GetValues(typeof(Gender))
    .Cast<string>()
    .Select(genderString => new SelectListItem 
    {
        Text = genderString,
        Value = genderString,
    }).AsEnumerable();

I came across the same issue. Using pd.read_table() on the same source file seemed to work. I could not trace the reason for this but it was a useful workaround for my case. Perhaps someone more knowledgeable can shed more light on why it worked.

Edit: I found that this error creeps up when you have some text in your file that does not have the same format as the actual data. This is usually header or footer information (greater than one line, so skip_header doesn't work) which will not be separated by the same number of commas as your actual data (when using read_csv). Using read_table uses a tab as the delimiter which could circumvent the users current error but introduce others.

I usually get around this by reading the extra data into a file then use the read_csv() method.

The exact solution might differ depending on your actual file, but this approach has worked for me in several cases

DateTime.Now.ToString("dd/MM/yyyy");

If id is sequential starting at 1, the simplest (and quickest) would be:

UPDATE `table` 
SET uid = ELT(id, 2952, 4925, 1592) 
WHERE id IN (1,2,3)

As ELT() returns the Nth element of the list of strings: str1 if N = 1, str2 if N = 2, and so on. Returns NULL if N is less than 1 or greater than the number of arguments.

Clearly, the above code only works if id is 1, 2, or 3. If id was 10, 20, or 30, either of the following would work:

UPDATE `table` 
SET uid = CASE id 
WHEN 10 THEN 2952 
WHEN 20 THEN 4925 
WHEN 30 THEN 1592 END CASE 
WHERE id IN (10, 20, 30)

or the simpler:

UPDATE `table` 
SET uid = ELT(FIELD(id, 10, 20, 30), 2952, 4925, 1592) 
WHERE id IN (10, 20, 30)

As FIELD() returns the index (position) of str in the str1, str2, str3, ... list. Returns 0 if str is not found.

The value attribute on submit-type <input> elements controls the text displayed.

<input type="submit" class="like" value="Like" />

Generally, I use null for values that I know can have a "null" state; for example

if(jane.isManager == false){
  jane.employees = null
}

Otherwise, if its a variable or function that's not defined yet (and thus, is not "usable" at the moment) but is supposed to be setup later, I usually leave it undefined.

In my app, I had similar problem: 2 line of string and, eventually, add "..." if the string was too long. I used this code in xml file into textview tag:

android:maxLines="2"
android:ellipsize="end"
android:singleLine="false"

JLS clearly says

An array initializer creates an array and provides initial values for all its components.

and this is irrespective of whether the array is an instance variable or local variable or class variable.

Default values for primitive types : docs

For objects default values is null.

You've tagged this as C++ as well as C.

If you're using C++ things are a lot easier. The standard template library has a template called vector which allows you to dynamically build up a list of objects.

#include <stdio.h>
#include <vector>

typedef std::vector<char*> words;

int main(int argc, char** argv) {

        words myWords;

        myWords.push_back("Hello");
        myWords.push_back("World");

        words::iterator iter;
        for (iter = myWords.begin(); iter != myWords.end(); ++iter) {
                printf("%s ", *iter);
        }

        return 0;
}

If you're using C things are a lot harder, yes malloc, realloc and free are the tools to help you. You might want to consider using a linked list data structure instead. These are generally easier to grow but don't facilitate random access as easily.

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

typedef struct s_words {
        char* str;
        struct s_words* next;
} words;

words* create_words(char* word) {
        words* newWords = malloc(sizeof(words));
        if (NULL != newWords){
                newWords->str = word;
                newWords->next = NULL;
        }
        return newWords;
}

void delete_words(words* oldWords) {
        if (NULL != oldWords->next) {
                delete_words(oldWords->next);
        }
        free(oldWords);
}

words* add_word(words* wordList, char* word) {
        words* newWords = create_words(word);
        if (NULL != newWords) {
                newWords->next = wordList;
        }
        return newWords;
}

int main(int argc, char** argv) {

        words* myWords = create_words("Hello");
        myWords = add_word(myWords, "World");

        words* iter;
        for (iter = myWords; NULL != iter; iter = iter->next) {
                printf("%s ", iter->str);
        }
        delete_words(myWords);
        return 0;
}

Yikes, sorry for the worlds longest answer. So WRT to the "don't want to use a linked list comment":

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

typedef struct {
    char** words;
    size_t nWords;
    size_t size;
    size_t block_size;
} word_list;

word_list* create_word_list(size_t block_size) {
    word_list* pWordList = malloc(sizeof(word_list));
    if (NULL != pWordList) {
        pWordList->nWords = 0;
        pWordList->size = block_size;
        pWordList->block_size = block_size;
        pWordList->words = malloc(sizeof(char*)*block_size);
        if (NULL == pWordList->words) {
            free(pWordList);
            return NULL;    
        }
    }
    return pWordList;
}

void delete_word_list(word_list* pWordList) {
    free(pWordList->words);
    free(pWordList);
}

int add_word_to_word_list(word_list* pWordList, char* word) {
    size_t nWords = pWordList->nWords;
    if (nWords >= pWordList->size) {
        size_t newSize = pWordList->size + pWordList->block_size;
        void* newWords = realloc(pWordList->words, sizeof(char*)*newSize); 
        if (NULL == newWords) {
            return 0;
        } else {    
            pWordList->size = newSize;
            pWordList->words = (char**)newWords;
        }

    }

    pWordList->words[nWords] = word;
    ++pWordList->nWords;


    return 1;
}

char** word_list_start(word_list* pWordList) {
        return pWordList->words;
}

char** word_list_end(word_list* pWordList) {
        return &pWordList->words[pWordList->nWords];
}

int main(int argc, char** argv) {

        word_list* myWords = create_word_list(2);
        add_word_to_word_list(myWords, "Hello");
        add_word_to_word_list(myWords, "World");
        add_word_to_word_list(myWords, "Goodbye");

        char** iter;
        for (iter = word_list_start(myWords); iter != word_list_end(myWords); ++iter) {
                printf("%s ", *iter);
        }

        delete_word_list(myWords);

        return 0;
}

I recently had this error on a fresh OSX install of Node using homebrew. Brew installed the latest at the time 13.8.0.

I downgraded the last "stable" release of node.

sudo npm install -g n  ## Installs Node Version Switcher
sudo n stable          ## To switch to latest stable version

Then the rest of my npm installs finished and passed the dreaded gprc errors!

RedirectMatch uses a regular expression that is matched against the URL path. And your regular expression /contact.php just means any URL path that contains /contact.php but not just any URL path that is exactly /contact.php. So use the anchors for the start and end of the string (^ and $):

RedirectMatch 301 ^/contact\.php$ /contact-us.php

@include('views.otherView', ['variable' => 1])

I add a picture, show configdifference between mirror and bare. The left is bare, right is mirror. You can be clear, mirror's config file have fetch key, which means you can update it,by git remote update or git fetch --all

Your project needs to reference assembly System.Web.dll. Server is an object of type HttpServerUtility. Example:

HttpContext.Current.Server.MapPath(path);

name is deprecated for link targets, and invalid in HTML5. It no longer works at least in latest Firefox (v13). Change <a name="hello"> to<a id="hello">

The target does not need to be an <a> tag, it can be <p id="hello"> or <h2 id="hello"> etc. which is often cleaner code.

As other posts say clearly, name is still used (needed) in forms. It is also still used in META tags.

You can use CSS3 transitions with rotate() to spin the image on hover.

Rotating image :

img {_x000D_
  border-radius: 50%;_x000D_
  -webkit-transition: -webkit-transform .8s ease-in-out;_x000D_
          transition:         transform .8s ease-in-out;_x000D_
}_x000D_
img:hover {_x000D_
  -webkit-transform: rotate(360deg);_x000D_
          transform: rotate(360deg);_x000D_
}

<img src="https://i.stack.imgur.com/BLkKe.jpg" width="100" height="100"/>

Here is a fiddle DEMO

One simple way to do this is with xargs -p or gnu parallel --interactive.

I like the behavior of xargs a little better for this because it executes each command immediately after the prompt like other interactive unix commands, rather than collecting the yesses to run at the end. (You can Ctrl-C after you get through the ones you wanted.)

e.g.,

echo *.xml | xargs -p -n 1 -J {} mv {} backup/

The problem you are reporting seems to me caused by the following:

1. you are trying to compile C code and the source file has .cpp extension
2. you are trying to compile C++ code and the source file has .c extension

In such situation Eclipse cannot recognize the proper compiler to use.

I had the same issue and did all the tips with no luck. Finally when I changed password to something different, for some reason it worked! (the initial password or the new one did not have any special characters)

string x ="Hi ,World";
string y = x;
char[] whitespace = new char[]{ ' ',\t'};          
string[] fooArray = y.Split(whitespace);  // now you have an array of 3 strings
y = String.Join(" ", fooArray);
string[] target = { "Hi", "World", "VW_Slep" };

for (int i = 0; i < target.Length; i++)
{
    string v = target[i];
    string results = Array.Find(fooArray, element => element.StartsWith(v, StringComparison.Ordinal));
    //
    if (results != null)
    { MessageBox.Show(results); }

}

UPDATE mytable SET spares = CONCAT(spares, ',', '818') WHERE id = 1

not working for me.

spares is NULL by default but its varchar

You cannot use <li href="#" since it belongs to <a href="#" that's why it wasn't working, change it and it's all good.

Here is working JSFiddle which shows you how to create bootstrap popover.

Relevant parts of the code is below:

HTML:

<!-- 
Note: Popover content is read from "data-content" and "title" tags.
-->
<a tabindex="0"
   class="btn btn-lg btn-primary" 
   role="button" 
   data-html="true" 
   data-toggle="popover" 
   data-trigger="focus" 
   title="<b>Example popover</b> - title" 
   data-content="<div><b>Example popover</b> - content</div>">Example popover</a>

JavaScript:

$(function(){
    // Enables popover
    $("[data-toggle=popover]").popover();
});

And by the way, you always need at least $("[data-toggle=popover]").popover(); to enable the popover. But in place of data-toggle="popover" you can also use id="my-popover" or class="my-popover". Just remember to enable them using e.g: $("#my-popover").popover(); in those cases.

Here is the link to the complete spec: Bootstrap Popover

Bonus:

If for some reason you don't like or cannot read content of a popup from the data-content and title tags. You can also use e.g. hidden divs and a bit more JavaScript. Here is an example about that.

As of PowerShell 2, simple:

$recipients = $addresses -split "; "

Note that the right hand side is actually a case-insensitive regular expression, not a simple match. Use csplit to force case-sensitivity. See about_Split for more details.

(For fellow googlers)

There is also Boost::date_time :

#include <boost/date_time/posix_time/posix_time.hpp>

boost::posix_time::ptime date_time = boost::posix_time::microsec_clock::universal_time();

You can not "attach" a SASS/SCSS file to an HTML document.

SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.

There are client-side alternatives to SASS that can be compiled in the browser using javascript such as LESS CSS, though I advise you compile to CSS for production use.

It's as simple as adding 2 lines of code to your HTML file.

<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>

Just got a solution to get height and width of a custom view:

@Override
protected void onSizeChanged(int xNew, int yNew, int xOld, int yOld){
    super.onSizeChanged(xNew, yNew, xOld, yOld);

    viewWidth = xNew;
    viewHeight = yNew;
}

Its working in my case.

The > character does not redirect the standard error. It's useful when you want to save legitimate output without mucking up a file with error messages. But what if the error messages are what you want to save? This is quite common during troubleshooting. The solution is to use a greater-than sign followed by an ampersand. (This construct works in almost every modern UNIX shell.) It redirects both the standard output and the standard error. For instance:

$ gcc invinitjig.c >& error-msg

Have a look there, if this helps: another forum

Normally, IIS would use the process identity (the user account it is running the worker process as) to access protected resources like file system or network.

With passthrough authentication, IIS will attempt to use the actual identity of the user when accessing protected resources.

If the user is not authenticated, IIS will use the application pool identity instead. If pool identity is set to NetworkService or LocalSystem, the actual Windows account used is the computer account.

The IIS warning you see is not an error, it's just a warning. The actual check will be performed at execution time, and if it fails, it'll show up in the log.

If start time is a datetime type then you can use something like

SELECT BookingId, StartTime
FROM Booking
WHERE StartTime >= '2012-03-08 00:00:00.000' 
AND StartTime <= '2012-03-08 01:00:00.000'

Obviously you would want to use your own values for the times but this should give you everything in that 1 hour period inclusive of both the upper and lower limit.

You can use the GETDATE() function to get todays current date.

this is the DOM element on which the event was hooked. this.id is its ID. No need to wrap it in a jQuery instance to get it, the id property reflects the attribute reliably on all browsers.

$("select").change(function() {    
    alert("Changed: " + this.id);
}

Live example

You're not doing this in your code sample, but if you were watching a container with several form elements, that would give you the ID of the container. If you want the ID of the element that triggered the event, you could get that from the event object's target property:

$("#container").change(function(event) {
    alert("Field " + event.target.id + " changed");
});

Live example

(jQuery ensures that the change event bubbles, even on IE where it doesn't natively.)

I understand that the Q does not want to use a library, but I will offer this for others coming from Google searches. @EricRowell mentioned a good plugin, but, there is also another plugin you can try, html2canvas.

In our case we are using layered transparent PNG's with z-index as a "product builder" widget. Html2canvas worked brilliantly to boil the stack down without pushing images, nor using complexities, workarounds, and the "non-responsive" canvas itself. We were not able to do this smoothly/sane with the vanilla canvas+JS.

First use z-index on absolute divs to generate layered content within a relative positioned wrapper. Then pipe the wrapper through html2canvas to get a rendered canvas, which you may leave as-is, or output as an image so that a client may save it.

Using set elements ... isn't always the best way. It would be useful if there were a distinct set string-elements ....

So, I use these functions in my .gdbinit:

define pstr
  ptype $arg0._M_dataplus._M_p
  printf "[%d] = %s\n", $arg0._M_string_length, $arg0._M_dataplus._M_p
end

define pcstr
  ptype $arg0
  printf "[%d] = %s\n", strlen($arg0), $arg0
end

Caveats:

• The first is c++ lib dependent as it accesses members of std::string, but is easily adjusted.
• The second can only be used on a running program as it calls strlen.

Dispatcher Controller are displayed in the figure all the incoming request is in intercepted by the dispatcher servlet that works as front controller. The dispatcher servlet gets an entry to handler mapping from the XML file and forwords the request to the Controller.

To create an option that needs no value, set the action ^[docs] of it to 'store_const', 'store_true' or 'store_false'.

Example:

parser.add_argument('-s', '--simulate', action='store_true')

git log --format="%h" | tail -1 gives you the commit hash (ie 0dd89fb), which you can feed into other commands, by doing something like

git diff `git log --format="%h" --after="1 day"| tail -1`..HEAD to view all the commits in the last day.

Just to offer another approach, based on the idea of the completion being the 'last visible' cell to be sent to cellForRow.

// Will be set when reload is called
var lastIndexPathToDisplay: IndexPath?

typealias ReloadCompletion = ()->Void

var reloadCompletion: ReloadCompletion?

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    // Setup cell

    if indexPath == self.lastIndexPathToDisplay {

        self.lastIndexPathToDisplay = nil

        self.reloadCompletion?()
        self.reloadCompletion = nil
    }

    // Return cell
...

func reloadData(completion: @escaping ReloadCompletion) {

    self.reloadCompletion = completion

    self.mainTable.reloadData()

    self.lastIndexPathToDisplay = self.mainTable.indexPathsForVisibleRows?.last
}

One possible issue is: If reloadData() has finished before the lastIndexPathToDisplay was set, the 'last visible' cell will be displayed before lastIndexPathToDisplay was set and the completion will not be called (and will be in 'waiting' state):

self.mainTable.reloadData()

// cellForRowAt could be finished here, before setting `lastIndexPathToDisplay`

self.lastIndexPathToDisplay = self.mainTable.indexPathsForVisibleRows?.last

If we reverse, we could end up with completion being triggered by scrolling before reloadData().

self.lastIndexPathToDisplay = self.mainTable.indexPathsForVisibleRows?.last

// cellForRowAt could trigger the completion by scrolling here since we arm 'lastIndexPathToDisplay' before 'reloadData()'

self.mainTable.reloadData()

In your html you can pass in an array for the name i.e

<input type="text" name="address[]" /> 

This way php will receive an array of addresses.

ln -s /mnt/usr/lib/* /usr/lib/

.center {
  position: absolute
  left: 50%;
  bottom: 5px;
}

.center:before {
    content: '';
    display: inline-block;
    margin-left: -50%;
}

It should be understood that from a performance standpoint there are no differences between @temp tables and #temp tables that favor variables. They reside in the same place (tempdb) and are implemented the same way. All the differences appear in additional features. See this amazingly complete writeup: https://dba.stackexchange.com/questions/16385/whats-the-difference-between-a-temp-table-and-table-variable-in-sql-server/16386#16386

Although there are cases where a temp table can't be used such as in table or scalar functions, for most other cases prior to v2016 (where even filtered indexes can be added to a table variable) you can simply use a #temp table.

The drawback to using named indexes (or constraints) in tempdb is that the names can then clash. Not just theoretically with other procedures but often quite easily with other instances of the procedure itself which would try to put the same index on its copy of the #temp table.

To avoid name clashes, something like this usually works:

declare @cmd varchar(500)='CREATE NONCLUSTERED INDEX [ix_temp'+cast(newid() as varchar(40))+'] ON #temp (NonUniqueIndexNeeded);';
exec (@cmd);

This insures the name is always unique even between simultaneous executions of the same procedure.

I have been striving for < 3 seconds for my applications, but I'm a bit picky when it comes to performance.

If you ask around, they say that people start to loose interest in the >= 7 second range, by 10-15 seconds you have typically lost them, unless you REALLY have something they want or need.

Just use the this reference

$(this).attr("id")

or

$(this).prop("id")

It seems you can cheat a bit using jetxee's algorithm. He is finding the first three toes fine, and you should be able to guess where the fourth is based off that.

Thread.sleep() could work in most cases, but usually if you're waiting, you are actually waiting for a particular condition or state to occur. Thread.sleep() does not guarantee that whatever you're waiting for has actually happened.

If you are waiting on a rest request for example maybe it usually return in 5 seconds, but if you set your sleep for 5 seconds the day your request comes back in 10 seconds your test is going to fail.

To remedy this JayWay has a great utility called Awatility which is perfect for ensuring that a specific condition occurs before you move on.

It has a nice fluent api as well

await().until(() -> 
{
    return yourConditionIsMet();
});

I have had occasion to need of an Enum class, for the purpose of decoding a binary file format. The features I happened to want is concise enum definition, the ability to freely create instances of the enum by either integer value or string, and a useful representation. Here's what I ended up with:

>>> class Enum(int):
...     def __new__(cls, value):
...         if isinstance(value, str):
...             return getattr(cls, value)
...         elif isinstance(value, int):
...             return cls.__index[value]
...     def __str__(self): return self.__name
...     def __repr__(self): return "%s.%s" % (type(self).__name__, self.__name)
...     class __metaclass__(type):
...         def __new__(mcls, name, bases, attrs):
...             attrs['__slots__'] = ['_Enum__name']
...             cls = type.__new__(mcls, name, bases, attrs)
...             cls._Enum__index = _index = {}
...             for base in reversed(bases):
...                 if hasattr(base, '_Enum__index'):
...                     _index.update(base._Enum__index)
...             # create all of the instances of the new class
...             for attr in attrs.keys():
...                 value = attrs[attr]
...                 if isinstance(value, int):
...                     evalue = int.__new__(cls, value)
...                     evalue._Enum__name = attr
...                     _index[value] = evalue
...                     setattr(cls, attr, evalue)
...             return cls
... 

A whimsical example of using it:

>>> class Citrus(Enum):
...     Lemon = 1
...     Lime = 2
... 
>>> Citrus.Lemon
Citrus.Lemon
>>> 
>>> Citrus(1)
Citrus.Lemon
>>> Citrus(5)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 6, in __new__
KeyError: 5
>>> class Fruit(Citrus):
...     Apple = 3
...     Banana = 4
... 
>>> Fruit.Apple
Fruit.Apple
>>> Fruit.Lemon
Citrus.Lemon
>>> Fruit(1)
Citrus.Lemon
>>> Fruit(3)
Fruit.Apple
>>> "%d %s %r" % ((Fruit.Apple,)*3)
'3 Apple Fruit.Apple'
>>> Fruit(1) is Citrus.Lemon
True

Key features:

• str(), int() and repr() all produce the most useful output possible, respectively the name of the enumartion, its integer value, and a Python expression that evaluates back to the enumeration.
• Enumerated values returned by the constructor are limited strictly to the predefined values, no accidental enum values.
• Enumerated values are singletons; they can be strictly compared with is

Andy's response worked for me by escaping $path:

git submodule foreach "(git checkout master; git pull; cd ..; git add \$path; git commit -m 'Submodule Sync')"

Nginx operates within the directory, so if you can't cd to that directory from the nginx user then it will fail (as does the stat command in your log). Make sure the www-user can cd all the way to the /username/test/static. You can confirm that the stat will fail or succeed by running

sudo -u www-data stat /username/test/static

In your case probably the /username directory is the issue here. Usually www-data does not have permissions to cd to other users home directories.

The best solution in that case would be to add www-data to username group:

gpasswd -a www-data username

and make sure that username group can enter all directories along the path:

chmod g+x /username && chmod g+x /username/test && chmod g+x /username/test/static

For your changes to work, restart nginx

nginx -s reload

That header file is not part of the C++ standard, is therefore non-portable, and should be avoided.

Moreover, even if there were some catch-all header in the standard, you would want to avoid it in lieu of specific headers, since the compiler has to actually read in and parse every included header (including recursively included headers) every single time that translation unit is compiled.

I suggest that you should not do it like this. Action methods should be designed to be easily unit-tested. In this case, you should not access data directly from the request, because if you do it like this, when you want to unit test this code you have to construct a HttpRequestMessage.

You should do it like this to let MVC do all the model binding for you:

[HttpPost]
public void Confirmation(YOURDTO yourobj)//assume that you define YOURDTO elsewhere
{
        //your logic to process input parameters.

}

In case you do want to access the request. You just access the Request property of the controller (not through parameters). Like this:

[HttpPost]
public void Confirmation()
{
    var content = Request.Content.ReadAsStringAsync().Result;
}

In MVC, the Request property is actually a wrapper around .NET HttpRequest and inherit from a base class. When you need to unit test, you could also mock this object.

So you know the key, value pair that you want to delete in advance? It's just much clearer to do this, then:

 table.delete(key);
 for (K key: table.keySet()) {
    // do whatever you need to do with the rest of the keys
 }

Yes, they're in the same "local scope", and actually code like this is common in Python:

if condition:
  x = 'something'
else:
  x = 'something else'

use(x)

Note that x isn't declared or initialized before the condition, like it would be in C or Java, for example.

In other words, Python does not have block-level scopes. Be careful, though, with examples such as

if False:
    x = 3
print(x)

which would clearly raise a NameError exception.

You can see all routes via rake:routes (this might help you).

add "MainContent_" to ID value!

Example: (Error)

document.getElementById("Password").value = text;

(ok!)

document.getElementById("**MainContent_**Password").value = text;

If the methods you used isn't working well with objects involving data types like Date, try this

Import _

import * as _ from 'lodash';

Deep clone object

myObjCopy = _.cloneDeep(myObj);

You might want to do it like this:

DateTime? lastPostDate =  (DateTime?)(reader.IsDbNull(3) ? null : reader[3]); 

The problem you are having is that the ternary operator wants a viable cast between the left and right sides. And null can't be cast to DateTime.

Note the above works because both sides of the ternary are object's. The object is explicitly cast to DateTime? which works: as long as reader[3] is in fact a date.

Create a table layout panel with two columns in your form and name it tlpFields.

Then, simply add new control to table layout panel (in this case I added 5 labels in column-1 and 5 textboxes in column-2).

tlpFields.RowStyles.Clear();  //first you must clear rowStyles

for (int ii = 0; ii < 5; ii++)
{
    Label l1= new Label();
    TextBox t1 = new TextBox();

    l1.Text = "field : ";

    tlpFields.Controls.Add(l1, 0, ii);  // add label in column0
    tlpFields.Controls.Add(t1, 1, ii);  // add textbox in column1

    tlpFields.RowStyles.Add(new RowStyle(SizeType.Absolute,30)); // 30 is the rows space
}

Finally, run the code.

No, the action should be the name of php file. With on click you may only call JavaScript. And please be aware the hiding your code from the user undermines trust. JS runs on the browser so some trust is needed.

Check for null

$column is null
isnull($column)

Check for empty

$column != ""

However, you should always set NOT NULL for column,

Within your app theme you can set the android:itemBackground property to change the color of the action menu.

For example:

<style name="AppThemeDark" parent="Theme.AppCompat.Light.DarkActionBar">_x000D_
        <item name="colorPrimary">@color/drk_colorPrimary</item>_x000D_
        <item name="colorPrimaryDark">@color/drk_colorPrimaryDark</item>_x000D_
        <item name="colorAccent">@color/drk_colorAccent</item>_x000D_
        <item name="actionBarStyle">@style/NoTitle</item>_x000D_
        <item name="windowNoTitle">true</item>_x000D_
        <item name="android:textColor">@color/white</item>_x000D_
_x000D_
        <!-- THIS IS WHERE YOU CHANGE THE COLOR -->_x000D_
        <item name="android:itemBackground">@color/drk_colorPrimary</item>_x000D_
</style>

You should use a VARCHAR with an ASCII character encoding. URLs are percent encoded and international domain names use punycode so ASCII is enough to store them. This will use much less space than UTF8.

VARCHAR(512) CHARACTER SET 'ascii' COLLATE 'ascii_general_ci' NOT NULL

Or

public class Section
{
  public String Head { get; set; }
  private readonly List<string> _subHead = new List<string>();
  private readonly List<string> _content = new List<string>();

  public IEnumerable<string> SubHead { get { return _subHead; } }
  public IEnumerable<string> Content { get { return _content; } }

  public void AddContent(String argValue)
  {
    _content.Add(argValue);
  }

  public void AddSubHeader(String argValue)
  {
    _subHead.Add(argValue);
  }
}

All depends on how much of the implementaton of content and subhead you want to hide.

This article covers various ways of concatenating strings in SQL, including an improved version of your code which doesn't XML-encode the concatenated values.

SELECT ID, abc = STUFF
(
    (
        SELECT ',' + name
        FROM temp1 As T2
        -- You only want to combine rows for a single ID here:
        WHERE T2.ID = T1.ID
        ORDER BY name
        FOR XML PATH (''), TYPE
    ).value('.', 'varchar(max)')
, 1, 1, '')
FROM temp1 As T1
GROUP BY id

To understand what's happening, start with the inner query:

SELECT ',' + name
FROM temp1 As T2
WHERE T2.ID = 42 -- Pick a random ID from the table
ORDER BY name
FOR XML PATH (''), TYPE

Because you're specifying FOR XML, you'll get a single row containing an XML fragment representing all of the rows.

Because you haven't specified a column alias for the first column, each row would be wrapped in an XML element with the name specified in brackets after the FOR XML PATH. For example, if you had FOR XML PATH ('X'), you'd get an XML document that looked like:

<X>,aaa</X>
<X>,bbb</X>
...

But, since you haven't specified an element name, you just get a list of values:

,aaa,bbb,...

The .value('.', 'varchar(max)') simply retrieves the value from the resulting XML fragment, without XML-encoding any "special" characters. You now have a string that looks like:

',aaa,bbb,...'

The STUFF function then removes the leading comma, giving you a final result that looks like:

'aaa,bbb,...'

It looks quite confusing at first glance, but it does tend to perform quite well compared to some of the other options.

It's a bit late but I came across this post.

It's not perfect but here's what I do.

HTML Code

<div class="showcase-menu-social"><img class="margin-left-20" src="images/graphics/facebook-50x50.png" alt="facebook-50x50" width="50" height="50" /><img class="margin-left-20" src="images/graphics/twitter-50x50.png" alt="twitter-50x50" width="50" height="50" /><img class="margin-left-20" src="images/graphics/youtube-50x50.png" alt="youtube-50x50" width="50" height="50" /></div>

CSS Code

.showcase-menu {
  margin-left:20px;
    margin-right:20px;
    padding: 0px 20px 0px 20px;
    background-color: #C37500;
    behavior: url(/css/border-radius.htc);
  border-radius: 20px;
    }

.showcase-menu-social img:hover {
  background-color: #C37500;
  opacity:0.7 !important;
  filter:alpha(opacity=70) !important; /* For IE8 and earlier */
  box-shadow: 0 0 0px #000000 !important;
}

Now my border radius of 20px matches up exactly with the image border radius. As you can see the .showcase-menu has the same background as the .showcase-menu-social. What this does is to allow the 'opacity' to take effect and no 'square' background or border shows, thus the image slightly reduces it's saturation on hover.

It's a nice effect and does give the viewer the feedback that the image is in focus. I'm fairly sure on a darker background, it would have even a better effect.

The nice thing is that this is valid HTML-CSS code and will validate. To be honest, it should work on non-image elements just as good as images.

This is a major issue. One of the big points of unit tests is to know where, when, and how something broke ASAP. Thus decreasing a significant amount of development & QA effort. If all that is tested is the public, then you don't have honest coverage and delineation of the internals of the class.

I've found one of the best ways to do this is simply add the test reference to the project and put the tests in a class parallel to the private methods. Put in the appropriate build logic so that the tests don't build into the final project.

Then you have all the benefits of having these methods tested and you can find problems in seconds versus minutes or hours.

So in summary, yes, unit test your private methods.

Yes you can use Boolean/boolean instead.

First one is Object and second one is primitive type.

• On first one, you will get more methods which will be useful.

• _{Second one is cheap considering memory expense} The second will save you a lot more memory, so go for it

Now choose your way.

This one is similar to the solution above using .NET Framework 3.0, but it solved the issue of compile-time safety support.

public  static class ControlExtension
{
    delegate void SetPropertyValueHandler<TResult>(Control souce, Expression<Func<Control, TResult>> selector, TResult value);

    public static void SetPropertyValue<TResult>(this Control source, Expression<Func<Control, TResult>> selector, TResult value)
    {
        if (source.InvokeRequired)
        {
            var del = new SetPropertyValueHandler<TResult>(SetPropertyValue);
            source.Invoke(del, new object[]{ source, selector, value});
        }
        else
        {
            var propInfo = ((MemberExpression)selector.Body).Member as PropertyInfo;
            propInfo.SetValue(source, value, null);
        }
    }
}

To use:

this.lblTimeDisplay.SetPropertyValue(a => a.Text, "some string");
this.lblTimeDisplay.SetPropertyValue(a => a.Visible, false);

The compiler will fail if the user passes the wrong data type.

this.lblTimeDisplay.SetPropertyValue(a => a.Visible, "sometext");

Just set the frame property of the tableHeaderView.

Here is the contents of the configuration file I used to support both .NET 2.0 and .NET 4 assemblies:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <!-- http://msdn.microsoft.com/en-us/library/w4atty68.aspx -->
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" />
    <supportedRuntime version="v2.0.50727" />
  </startup>
</configuration>

Also, here’s a simplified version of the PowerShell 1.0 compatible code I used to execute our scripts from the passed in command line arguments:

class Program {
  static void Main( string[] args ) {
    Console.WriteLine( ".NET " + Environment.Version );

    string script = "& " + string.Join( " ", args );
    Console.WriteLine( script );
    Console.WriteLine( );

    // Simple host that sends output to System.Console
    PSHost host = new ConsoleHost( this );
    Runspace runspace = RunspaceFactory.CreateRunspace( host );

    Pipeline pipeline = runspace.CreatePipeline( );
    pipeline.Commands.AddScript( script );

    try {
      runspace.Open( );
      IEnumerable<PSObject> output = pipeline.Invoke( );
      runspace.Close( );

      // ...
    }
    catch( RuntimeException ex ) {
      string psLine = ex.ErrorRecord.InvocationInfo.PositionMessage;
      Console.WriteLine( "error : {0}: {1}{2}", ex.GetType( ), ex.Message, psLine );
      ExitCode = -1;
    }
  }
}

In addition to the basic error handling shown above, we also inject a trap statement into the script to display additional diagnostic information (similar to Jeffrey Snover's Resolve-Error function).

You can use the QMessage object to create a Message Box then add buttons :

QMessageBox msgBox;
msgBox.setWindowTitle("title");
msgBox.setText("Question");
msgBox.setStandardButtons(QMessageBox::Yes);
msgBox.addButton(QMessageBox::No);
msgBox.setDefaultButton(QMessageBox::No);
if(msgBox.exec() == QMessageBox::Yes){
  // do something
}else {
  // do something else
}

You can't install Integration Services with it. Express does not support Integration Services. So if you want build say SSIS-packages you'll need at least Standard Edition.

See more here.

You can even use a version range with pip install command. Something like this:

pip install 'stevedore>=1.3.0,<1.4.0'

And if the package is already installed and you want to downgrade it add --force-reinstall like this:

pip install 'stevedore>=1.3.0,<1.4.0' --force-reinstall

I'm on Ubuntu 20.04 and I kept getting the message that soon I wouldn't be able to login from console. I was terribly confused. Finally, I got to the URL below which will work. But you need to know how to create a PAT (Personal Access Token) which you are going to have to keep in a file on your computer.

Here's what the final URL will look like:

git push https://[email protected]/user-name/repo.git

long PAT (Personal Access Token) value -- The entire long value between the // and the @ sign in the url is your PAT.

user-name will be your exact username

repo.git will be your exact repo name

You need to generate a PAT following the steps at: https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token

That will give you the PAT value that you will place in your URL.

When you create the PAT make sure you choose the following options so it has the ability to allow you to manage your REPOs.

Save Your PAT Or Lose It

Once you have your PAT. You're going to need to save it in a file locally so you can use it again. If you don't save it somewhere there is no way to ever see it again and you'll be forced to create a new PAT

Now you're going to need at the very least :

1. a way to display it in your console so you can see it again.
2. or, A way to copy it to your clipboard automatically.

For 1, just use :

$ cat ~/files/myPatFile.txt

Where the path is a real path to the location and file where you stored your PAT value.

For 2

$ xclip -selection clipboard < ~/files/myPatFile.txt

That'll copy the contents of the file to the clipboard so you can use your PAT more easily.

FYI - if you don't have xclip do the following:

$ sudo apt-get install xclip

Downloads and installs xclip. If you don't have apt-get, you might need to use another installer (like yum)

A DataSet already contains DataTables. You can just use:

DataTable firstTable = dataSet.Tables[0];

or by name:

DataTable customerTable = dataSet.Tables["Customer"];

Note that you should have using statements for your SQL code, to ensure the connection is disposed properly:

using (SqlConnection conn = ...)
{
    // Code here...
}

Modal In Out Effect with Animate.css and jquery Very easy and short code.

In HTML:

<div class="modal fade" id="DirectorModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog bounceInDown animated"><!-- Add here Modal COME Effect "Animate.css" -->
        <div class="modal-content">
         <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">&times;</button>
           <h4 class="modal-title">Modal Header</h4>
          </div>
          <div class="modal-body">
          </div>
        </div>
    </div>
</div>

this bellow jquery code i got from: https://codepen.io/nhembram/pen/PzyYLL

i am modify this for regular use.

jquery code:

<script>
    $(document).ready(function () {
    // BS MODAL OPEN CLOSE EFFECT  ---------------------------------
        var timeoutHandler = null;
        $('.modal').on('hide.bs.modal', function (e) {
            var anim = $('.modal-dialog').removeClass('bounceInDown').addClass('fadeOutDownBig'); // Model Come class Remove & Out effect class add
            if (timeoutHandler) clearTimeout(timeoutHandler);
            timeoutHandler = setTimeout(function() {
                $('.modal-dialog').removeClass('fadeOutDownBig').addClass('bounceInDown'); // Model Out class Remove & Come effect class add
            }, 500); // some delay for complete Animation
        });
    });
    </script>

It looks to me like the background images aren't actually background images...the site has the background images and the quotes in sibling divs with the children of the div containing the images having been assigned position: fixed; The quotes div is also given a transparent background.

wrapper div{
   image wrapper div{
       div for individual image{ <--- Fixed position
          image <--- relative position
       }
   }
   quote wrapper div{
       div for individual quote{
          quote
       }
   }
 }

I have created the Makefile project using cmake on Ubuntu 16.04.

When created the eclipse project for the Makefiles which cmake generated I created the new project like so:

File --> new --> Makefile project with existing code.

Only after couple of times doing that I have noticed that the default setting for the "Toolchain for indexer settings" is none. In my case I have changed it to Linux GCC and all the errors disappeared.

Hope it helps and let me know if it is not a legit solution.

Cheers,

Guy.

I found the easiest way was to:

1. Convert the samples column into a DataFrame
2. Joining with the original df
3. Melting

Shown here:

    df.samples.apply(lambda x: pd.Series(x)).join(df).\
melt(['subject','trial_num'],[0,1,2],var_name='sample')

        subject  trial_num sample  value
    0         1          1      0  -0.24
    1         1          2      0   0.14
    2         1          3      0  -0.67
    3         2          1      0  -1.52
    4         2          2      0  -0.00
    5         2          3      0  -1.73
    6         1          1      1  -0.70
    7         1          2      1  -0.70
    8         1          3      1  -0.29
    9         2          1      1  -0.70
    10        2          2      1  -0.72
    11        2          3      1   1.30
    12        1          1      2  -0.55
    13        1          2      2   0.10
    14        1          3      2  -0.44
    15        2          1      2   0.13
    16        2          2      2  -1.44
    17        2          3      2   0.73

It's worth noting that this may have only worked because each trial has the same number of samples (3). Something more clever may be necessary for trials of different sample sizes.

For all browser support, especially on Android, perhaps you can add this:

try{
    blob = new Blob(byteArrays, {type : contentType});
}
catch(e){
    // TypeError old Google Chrome and Firefox
    window.BlobBuilder = window.BlobBuilder ||
                         window.WebKitBlobBuilder ||
                         window.MozBlobBuilder ||
                         window.MSBlobBuilder;
    if(e.name == 'TypeError' && window.BlobBuilder){
        var bb = new BlobBuilder();
        bb.append(byteArrays);
        blob = bb.getBlob(contentType);
    }
    else if(e.name == "InvalidStateError"){
        // InvalidStateError (tested on FF13 WinXP)
        blob = new Blob(byteArrays, {type : contentType});
    }
    else{
        // We're screwed, blob constructor unsupported entirely
    }
}

The best way to wait for page loads when using the Java bindings for WebDriver is to use the Page Object design pattern with PageFactory. This allows you to utilize the AjaxElementLocatorFactory which to put it simply acts as a global wait for all of your elements. It has limitations on elements such as drop-boxes or complex javascript transitions but it will drastically reduce the amount of code needed and speed up test times. A good example can be found in this blogpost. Basic understanding of Core Java is assumed.

Introduction

It represents the scope (the lifetime) of the bean. This is easier to understand if you are familiar with "under the covers" working of a basic servlet web application: How do servlets work? Instantiation, sessions, shared variables and multithreading.

@Request/View/Flow/Session/ApplicationScoped

A @RequestScoped bean lives as long as a single HTTP request-response cycle (note that an Ajax request counts as a single HTTP request too). A @ViewScoped bean lives as long as you're interacting with the same JSF view by postbacks which call action methods returning null/void without any navigation/redirect. A @FlowScoped bean lives as long as you're navigating through the specified collection of views registered in the flow configuration file. A @SessionScoped bean lives as long as the established HTTP session. An @ApplicationScoped bean lives as long as the web application runs. Note that the CDI @Model is basically a stereotype for @Named @RequestScoped, so same rules apply.

Which scope to choose depends solely on the data (the state) the bean holds and represents. Use @RequestScoped for simple and non-ajax forms/presentations. Use @ViewScoped for rich ajax-enabled dynamic views (ajaxbased validation, rendering, dialogs, etc). Use @FlowScoped for the "wizard" ("questionnaire") pattern of collecting input data spread over multiple pages. Use @SessionScoped for client specific data, such as the logged-in user and user preferences (language, etc). Use @ApplicationScoped for application wide data/constants, such as dropdown lists which are the same for everyone, or managed beans without any instance variables and having only methods.

Abusing an @ApplicationScoped bean for session/view/request scoped data would make it to be shared among all users, so anyone else can see each other's data which is just plain wrong. Abusing a @SessionScoped bean for view/request scoped data would make it to be shared among all tabs/windows in a single browser session, so the enduser may experience inconsitenties when interacting with every view after switching between tabs which is bad for user experience. Abusing a @RequestScoped bean for view scoped data would make view scoped data to be reinitialized to default on every single (ajax) postback, causing possibly non-working forms (see also points 4 and 5 here). Abusing a @ViewScoped bean for request, session or application scoped data, and abusing a @SessionScoped bean for application scoped data doesn't affect the client, but it unnecessarily occupies server memory and is plain inefficient.

Note that the scope should rather not be chosen based on performance implications, unless you really have a low memory footprint and want to go completely stateless; you'd need to use exclusively @RequestScoped beans and fiddle with request parameters to maintain the client's state. Also note that when you have a single JSF page with differently scoped data, then it's perfectly valid to put them in separate backing beans in a scope matching the data's scope. The beans can just access each other via @ManagedProperty in case of JSF managed beans or @Inject in case of CDI managed beans.

• Difference between View and Request scope in managed beans
• Advantages of using JSF Faces Flow instead of the normal navigation system
• Communication in JSF2 - Managed bean scopes

@CustomScoped/NoneScoped/Dependent

It's not mentioned in your question, but (legacy) JSF also supports @CustomScoped and @NoneScoped, which are rarely used in real world. The @CustomScoped must refer a custom Map<K, Bean> implementation in some broader scope which has overridden Map#put() and/or Map#get() in order to have more fine grained control over bean creation and/or destroy.

The JSF @NoneScoped and CDI @Dependent basically lives as long as a single EL-evaluation on the bean. Imagine a login form with two input fields referring a bean property and a command button referring a bean action, thus with in total three EL expressions, then effectively three instances will be created. One with the username set, one with the password set and one on which the action is invoked. You normally want to use this scope only on beans which should live as long as the bean where it's being injected. So if a @NoneScoped or @Dependent is injected in a @SessionScoped, then it will live as long as the @SessionScoped bean.

See also:

• Expire specific managed bean instance after time interval
• what is none scope bean and when to use it?
• What is the default Managed Bean Scope in a JSF 2 application?

Flash scope

As last, JSF also supports the flash scope. It is backed by a short living cookie which is associated with a data entry in the session scope. Before the redirect, a cookie will be set on the HTTP response with a value which is uniquely associated with the data entry in the session scope. After the redirect, the presence of the flash scope cookie will be checked and the data entry associated with the cookie will be removed from the session scope and be put in the request scope of the redirected request. Finally the cookie will be removed from the HTTP response. This way the redirected request has access to request scoped data which was been prepared in the initial request.

This is actually not available as a managed bean scope, i.e. there's no such thing as @FlashScoped. The flash scope is only available as a map via ExternalContext#getFlash() in managed beans and #{flash} in EL.

• How to show faces message in the redirected page
• Pass an object between @ViewScoped beans without using GET params
• CDI missing @ViewScoped and @FlashScoped

ALTER TABLE can do multiple table alterations in one statement, but MODIFY COLUMN can only work on one column at a time, so you need to specify MODIFY COLUMN for each column you want to change:

ALTER TABLE webstore.Store
  MODIFY COLUMN ShortName VARCHAR(100),
  MODIFY COLUMN UrlShort VARCHAR(100);

Also, note this warning from the manual:

When you use CHANGE or MODIFY, column_definition must include the data type and all attributes that should apply to the new column, other than index attributes such as PRIMARY KEY or UNIQUE. Attributes present in the original definition but not specified for the new definition are not carried forward.

var sb = new StringBuilder();
sb.Append(beforeText);
sb.Insert(2, insertText);
afterText = sb.ToString();

You can also use the react-fontawesome icon library. Here's the link: react-fontawesome

From the NPM page, just install via npm:

npm install --save react-fontawesome

Require the module:

var FontAwesome = require('react-fontawesome');

And finally, use the <FontAwesome /> component and pass in attributes to specify icon and styling:

var MyComponent = React.createClass({
  render: function () {
    return (
      <FontAwesome
        className='super-crazy-colors'
        name='rocket'
        size='2x'
        spin
        style={{ textShadow: '0 1px 0 rgba(0, 0, 0, 0.1)' }}
      />
    );
  }
});

Don't forget to add the font-awesome CSS to index.html:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.1/css/font-awesome.min.css">

A couple of additional points re use of vector here.

Unlike ArrayList and Array in Java, you don't need to do anything special to treat a vector as an array - the underlying storage in C++ is guaranteed to be contiguous and efficiently indexable.

Unlike ArrayList, a vector can efficiently hold primitive types without encapsulation as a full-fledged object.

When removing items from a vector, be aware that the items above the removed item have to be moved down to preserve contiguous storage. This can get expensive for large containers.

Make sure if you store complex objects in the vector that their copy constructor and assignment operators are efficient. Under the covers, C++ STL uses these during container housekeeping.

Advice about reserve()ing storage upfront (ie. at vector construction or initialilzation time) to minimize memory reallocation on later extension carries over from Java to C++.

So many answers have been given, but they don't get to the point. Let's fix this.

http://www.w3schools.com/bootstrap/bootstrap_ref_js_collapse.asp

To the point

1. Any attribute starting with data- is not parsed by the HTML5 parser.
2. Bootstrap uses the data-toggle attribute to create collapse functionality.

How to use: Only 2 Steps

1. Add class="collapse" to the element #A you want to collapse.
2. Add data-target="#A" and data-toggle="collapse".

Purpose: the data-toggle attribute allows us to create a control to collapse/expand a div (block) if we use Bootstrap.

You can't.

"The Samsung Emulator has the same functionality as the Generic Android Emulator, but varies with the size and appearance of the device."

The problem with Samsung is that they don't use a generic android image, they have custom apps and they react in custom ways and do weird things you wouldn't expect and when you're trying to fix bugs that's what you want. You cannot get that. You need access to a physical device to get the right ecosystem to hunt down the bugs and map out which intents work and how they work on that device. And sometimes there are errors that only occur on Samsung devices because some of the core rendering code is different as well. I've had errors where all Android devices except Samsung would work flawlessly but the scheme itself could not work on Samsung and had to be scrapped. The only thing Samsung allows is skinning and that won't properly note the changes in the rendering pipeline or how the samsung ecosystem deals with intents.

You can make the device look similar, that's worthless. I don't care what it looks like, I care whether this bug still affects that particular model or whether the tweak to the intents I made rectified the issue and I can't learn that from a pretty picture as the border to the same device.

You can use a combination of substring and lastIndexOf

Sample

var fileName = "test.jpg";
var fileExtension = fileName.substring(fileName.lastIndexOf('.') + 1); 

With the following command:

:%s/^M$//g

To get the ^M to appear, type CtrlV and then CtrlM. CtrlV tells Vim to take the next character entered literally.

I have issue with itextsharp and itextsharp.xmlworker dlls for exception-from-hresult-0x80131040 so I have removed those both dlls from references and downloaded new dlls directly from nuget packages, which resolved my issue.

May be this method can be useful to resolved the issue to other people.

Had the same problem in a Project we had taken over after another vendor built it. The problem was that while there were a number of commands written by the previous vendor in Global.asax.cs, which might lead you to believe it was in use, it was actually being ignored entirely. Global.asax wasn't inheriting from it, and it's easy to never see this file if the .cs file is present - you have to right-click Global.asax and click View Markup to actually see it.

Global.asax:

<%@ Application Language="C#" %>

Needed to be changed to:

<%@ Application Codebehind="Global.asax.cs" Inherits="ProjectNamespace.MvcApplication" Language="C#" %>

Where ProjectNamespace is whatever the namespace is of your Global.asax.cs class (usually the name of your Project).

In our case the file contained a bunch of inline code, some of which was copy-pasted from the .cs file, some not. We just dumped the inline code over to the .cs file and gradually merged our changes back in.

I did a little research and was able to write this code:

strbody = "<BODY style=font-size:11pt;font-family:Calibri>Good Morning;<p>We have completed our main aliasing process for today.  All assigned firms are complete.  Please feel free to respond with any questions.<p>Thank you.</BODY>"

apparently by setting the "font-size=11pt" instead of setting the font size <font size=5>, It allows you to select a specific font size like you normally would in a text editor, as opposed to selecting a value from 1-7 like my code was originally.

This link from simpLE MAn gave me some good info.

Try this:

-- http://lua-users.org/wiki/FileInputOutput

-- see if the file exists
function file_exists(file)
  local f = io.open(file, "rb")
  if f then f:close() end
  return f ~= nil
end

-- get all lines from a file, returns an empty 
-- list/table if the file does not exist
function lines_from(file)
  if not file_exists(file) then return {} end
  lines = {}
  for line in io.lines(file) do 
    lines[#lines + 1] = line
  end
  return lines
end

-- tests the functions above
local file = 'test.lua'
local lines = lines_from(file)

-- print all line numbers and their contents
for k,v in pairs(lines) do
  print('line[' .. k .. ']', v)
end

Try

$('table#test tr#3').remove();

if you use hashchange event with hash parser, you can prevent default action on links and change location.hash adding one character to have difference with id property of an element

$('a[href^=#]').on('click', function(e){
    e.preventDefault();
    location.hash = $(this).attr('href')+'/';
});

$(window).on('hashchange', function(){
    var a = /^#?chapter(\d+)-section(\d+)\/?$/i.exec(location.hash);
});

in modern browsers you can do the following...

button.addEventListener( 'click', () => {
    alert( 'only once!' );
}, { once: true } );

Incase of windows, after executing npm uninstall -g yarn, still if yarn did not uninstalled, then go to "C:\Users\username\AppData\Local" and remove the yarn folder. Close the cmd and reopen the cmd and execute yarn . it will give you message 'yarn' is not recognized as an internal or external command, operable program or batch file.

You are trying to set "++" on a jQuery element!

YOu could declare a js variable

var counter = 0;

and in jQuery code do:

$("#counter").html(counter++);

On my Mac r is installed in /usr/local/bin/r, add line below in .bash_profile solved the same problem:

alias r="LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8 r"

While most people have answered the question directly, I wanted to elaborate more on the concept behind it. First, I was drawn to the attention of IME when I created a default Login Activity. It generated some code for me which included the following:

<EditText
  android:id="@+id/password"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:hint="@string/prompt_password"
  android:imeActionId="@+id/login"
  android:imeActionLabel="@string/action_sign_in_short"
  android:imeOptions="actionUnspecified"
  android:inputType="textPassword"
  android:maxLines="1"
  android:singleLine="true"/>

You should already be familiar with the inputType attribute. This just informs Android the type of text expected such as an email address, password or phone number. The full list of possible values can be found here.

It was, however, the attribute imeOptions="actionUnspecified" that I didn't understand its purpose. Android allows you to interact with the keyboard that pops up from bottom of screen when text is selected using the InputMethodManager. On the bottom corner of the keyboard, there is a button, typically it says "Next" or "Done", depending on the current text field. Android allows you to customize this using android:imeOptions. You can specify a "Send" button or "Next" button. The full list can be found here.

With that, you can then listen for presses on the action button by defining a TextView.OnEditorActionListener for the EditText element. As in your example:

editText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(EditText v, int actionId, KeyEvent event) {
    if (actionId == EditorInfo.IME_ACTION_DONE) {
       //do here your stuff f
       return true;
    }
    return false;
    } 
});

Now in my example I had android:imeOptions="actionUnspecified" attribute. This is useful when you want to try to login a user when they press the enter key. In your Activity, you can detect this tag and then attempt the login:

    mPasswordView = (EditText) findViewById(R.id.password);
    mPasswordView.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView textView, int id, KeyEvent keyEvent) {
            if (id == R.id.login || id == EditorInfo.IME_NULL) {
                attemptLogin();
                return true;
            }
            return false;
        }
    });

The most common reasons for me are so that:

1. The layout can have a fixed width (yes, I know, I do a lot of work for designers who love fixed widths), and
2. So the layout can be centered by applying text-align: center to the body and then margin: auto to the left and right of the container div.

you shouldn't include c-files in other c-files. Instead create a header file where the function is declared that you want to call. Like so: file ClasseAusiliaria.h:

int addizione(int a, int b); // this tells the compiler that there is a function defined and the linker will sort the right adress to call out.

In your Main.c file you can then include the newly created header file:

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

int main(void)
{
    int risultato;
    risultato = addizione(5,6);
    printf("%d\n",risultato);
}

the alphanum function (self answered) have a bug, but I don't know why. For text "cas synt ls 75W140 1L" return "cassyntls75W1401", "L" from the end is missing some how.

Now I use

delimiter //
DROP FUNCTION IF EXISTS alphanum //
CREATE FUNCTION alphanum(prm_strInput varchar(255))
RETURNS VARCHAR(255)
DETERMINISTIC
BEGIN
  DECLARE i INT DEFAULT 1;
  DECLARE v_char VARCHAR(1);
  DECLARE v_parseStr VARCHAR(255) DEFAULT ' ';
WHILE (i <= LENGTH(prm_strInput) )  DO
  SET v_char = SUBSTR(prm_strInput,i,1);
  IF v_char REGEXP  '^[A-Za-z0-9]+$' THEN 
        SET v_parseStr = CONCAT(v_parseStr,v_char);  
  END IF;
  SET i = i + 1;
END WHILE;
RETURN trim(v_parseStr);
END
//

display: flex

.container {
  display: flex;
  justify-content: center;
}

Notes:

• It’s not a hack
• Browser support: flexbox

max-width & margin

You can horizontally center a block-level element by assigning a fixed width and setting margin-right and margin-left to auto.

.container ul {
  /* for IE below version 7 use `width` instead of `max-width` */
  max-width: 800px;
  margin-right: auto;
  margin-left: auto;
}

Notes:

• No container needed
• Requires (maximum) width of the centered element to be known

IE9+: transform: translatex(-50%) & left: 50%

This is similar to the quirky centering method which uses absolute positioning and negative margins.

.container {
  position: relative;
}

.container ul {
  position: absolute;
  left: 50%;
  transform: translatex(-50%);
}

Notes:

• The centered element will be removed from document flow. All elements will completely ignore of the centered element.
• This technique allows vertical centering by using top instead of left and translateY() instead of translateX(). The two can even be combined.
• Browser support: transform2d

IE8+: display: table & margin

Just like the first solution, you use auto values for right and left margins, but don’t assign a width. If you don’t need to support IE7 and below, this is better suited, although it feels kind of hacky to use the table property value for display.

.container ul {
  display: table;
  margin-right: auto;
  margin-left: auto;
}

IE8+: display: inline-block & text-align

Centering an element just like you would do with regular text is possible as well. Downside: You need to assign values to both a container and the element itself.

.container {
  text-align: center;
}

.container ul {
  display: inline-block;

  /* One most likely needs to realign flow content */
  text-align: initial;
}

Notes:

• Does not require to specify a (maximum) width
• Aligns flow content to the center (potentially unwanted side effect)
• Works kind of well with a dynamic number of menu items (i.e. in cases where you can’t know the width a single item will take up)

Very simple and to be commonly used:

function getDataURI($imagePath) {
    $finfo = new finfo(FILEINFO_MIME_TYPE);
    $type = $finfo->file($imagePath);
    return 'data:'.$type.';base64,'.base64_encode(file_get_contents($imagePath));
}

//Use the above function like below:
echo '<img src="'.getDataURI('./images/my-file.svg').'" alt="">';
echo '<img src="'.getDataURI('./images/my-file.png').'" alt="">';

Note: The Mime-Type of the file will be added automatically (taking help from this PHP documentation).

A lot of the above work. Just to add. If your textboxes are not directly on the form but are on other container objects like a GroupBox, you will have to get the GroupBox object and then iterate through the GroupBox to access the textboxes contained therein.

foreach(Control t in this.Controls.OfType<GroupBox>())
{
   foreach (Control tt in t.Controls.OfType<TextBox>())
   {
        // do stuff
   }
}

For those who want to do it from YAML with multiple data sources, there is a great blog post about it: https://springframework.guru/how-to-configure-multiple-data-sources-in-a-spring-boot-application/

It basically says you both need to configure data source properties and datasource like this:

@Bean
@Primary
@ConfigurationProperties("app.datasource.member")
public DataSourceProperties memberDataSourceProperties() {
    return new DataSourceProperties();
}

@Bean
@Primary
@ConfigurationProperties("app.datasource.member.hikari")
public DataSource memberDataSource() {
    return memberDataSourceProperties().initializeDataSourceBuilder()
            .type(HikariDataSource.class).build();
}

Do not forget to remove @Primary from other datasources.

if you use Sql Server

delete from Table where id between 79 and 296

After your edit : you now clarified that you want :

ID (>79 AND < 296)

So use this :

delete from Table where id > 79 and id < 296

In Java, this return value fails with jQuery Ajax GET:

return Response.status(200).entity(pojoObj).build();

But this works:

ResponseBuilder rb = Response.status(200).entity(pojoObj);
return rb.header("Access-Control-Allow-Origin", "*").build();

----

Full class:

@Path("/password")
public class PasswordStorage {
    @GET
    @Produces({ MediaType.APPLICATION_JSON })
    public Response getRole() {
        Contact pojoObj= new Contact();
        pojoObj.setRole("manager");

        ResponseBuilder rb = Response.status(200).entity(pojoObj);
        return rb.header("Access-Control-Allow-Origin", "*").build();

        //Fails jQuery: return Response.status(200).entity(pojoObj).build();
    }
}

In my case, simply removing the tc.log in /var/lib/mysql was enough to start mariadb/mysql again.

I had to change /etc/profile.d/java_env.sh to point to the new path and then logout/login.

$("#first").val(); // this will give you value of selected element. i.e. 1,2,3.

May this could helpful for some people.

Chances are you are extending from the wrong parent. If not, you can try adding the style to the toolbar layout directly, if you want to override the theme's settings.

In your toolbar layout:

 <android.support.v7.widget.Toolbar
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:id="@+id/toolbar"
      android:layout_width="match_parent"
      android:layout_height="?attr/actionBarSize"
      android:minHeight="?attr/actionBarSize"
      app:theme="@style/ToolBarStyle"
      app:popupTheme="@style/ToolBarPopupStyle"
      android:background="@color/actionbar_color" />

In your styles:

 <!-- ToolBar -->
  <style name="ToolBarStyle" parent="Theme.AppCompat">
      <item name="android:textColorPrimary">@android:color/white</item>
      <item name="android:textColorSecondary">@android:color/white</item>
      <item name="actionMenuTextColor">@android:color/white</item>      
      <item name="actionOverflowButtonStyle">@style/ActionButtonOverflowStyle</item>
      <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
 </style>

sudo chmod 777 DIR_NAME
cd DIR_NAME
git clone https://github.com/mygitusername/kivy.git

should work fine

Expanding on @Renaud idea, cors now provides a very easy way of doing this:

From cors official documentation found here:

" origin: Configures the Access-Control-Allow-Origin CORS header. Possible values: Boolean - set origin to true to reflect the request origin, as defined by req.header('Origin'), or set it to false to disable CORS. "

Hence we simply do the following:

const app = express();
const corsConfig = {
    credentials: true,
    origin: true,
};
app.use(cors(corsConfig));

Lastly I think it is worth mentioning that there are use cases where we would want to allow cross origin requests from anyone; for example, when building a public REST API.

NOTE: I would have liked to leave this as a comment on his answer, but unfortunately I don't have the reputation points.

If you want to delete only several of the selected files: you can't. The File API Working Draft you linked to contains a note:

The HTMLInputElement interface [HTML5] has a readonly FileList attribute, […]
[emphasis mine]

Reading a bit of the HTML 5 Working Draft, I came across the Common input element APIs. It appears you can delete the entire file list by setting the value property of the input object to an empty string, like:

document.getElementById('multifile').value = "";

BTW, the article Using files from web applications might also be of interest.

Strictly speaking; With no Java EE features your app hardly need an appserver at all ;-)

Like others have pointed out JBoss has a (more or less) full Java EE stack while Tomcat is a webcontainer only. JBoss can be configured to only serve as a webcontainer as well, it'd then just be a thin wrapper around the included tomcat webcontainer. That way you could have an almost as lightweight JBoss, which would actually just be a thin "wrapper" around Tomcat. That would be almost as lightweigth.

If you won't need any of the extras JBoss has to offer, go for the one you're most comfortable with. Which is easiest to configure and maintain for you?

Asp.Net Core 3 with System.Text.Json

public void ConfigureServices(IServiceCollection services)
{

    services
        .AddControllers()
        .AddJsonOptions(options => 
           options.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter())
        );

    //...
 }

You need the Microsoft.AspNet.WebApi.Core package.

You can see it in the .csproj file:

<Reference Include="System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\packages\Microsoft.AspNet.WebApi.Core.5.0.0\lib\net45\System.Web.Http.dll</HintPath>
</Reference>

I didn't have luck with any of these suggestions. My string contained unicode bullet points and I suspect they were causing grief in the calculation. I noticed UITextView was handling the drawing fine, so I looked to that to leverage its calculation. I did the following, which is probably not as optimal as the NSString drawing methods, but at least it's accurate. It's also slightly more optimal than initialising a UITextView just to call -sizeThatFits:.

NSTextContainer *textContainer = [[NSTextContainer alloc] initWithSize:CGSizeMake(width, CGFLOAT_MAX)];
NSLayoutManager *layoutManager = [[NSLayoutManager alloc] init];
[layoutManager addTextContainer:textContainer];

NSTextStorage *textStorage = [[NSTextStorage alloc] initWithAttributedString:formattedString];
[textStorage addLayoutManager:layoutManager];

const CGFloat formattedStringHeight = ceilf([layoutManager usedRectForTextContainer:textContainer].size.height);

If, like me, you landed here with:

• a pre-existing table,
• to which you need to add a new column, and
• also need to add a new unique constraint on the new column as well as an old one, AND
• be able to undo it all (i.e. write a down migration)

Here is what worked for me, utilizing one of the above answers and expanding it:

-- up

ALTER TABLE myoldtable ADD COLUMN newcolumn TEXT;
ALTER TABLE myoldtable ADD CONSTRAINT myoldtable_oldcolumn_newcolumn_key UNIQUE (oldcolumn, newcolumn);

---

ALTER TABLE myoldtable DROP CONSTRAINT myoldtable_oldcolumn_newcolumn_key;
ALTER TABLE myoldtable DROP COLUMN newcolumn;

-- down

The trick is to visit the original page using the 64-bit version of Internet Explorer. The site will then offer you the appropriate download options.

There is nothing wrong with your code. It should list all of the files and directories directly contained by the nominated directory.

The problem is most likely one of the following:

• The "." directory is not what you expect it to be. The "." pathname actually means the "current directory" or "working directory" for the JVM. You can verify what directory "." actually is by printing out dir.getCanonicalPath().

• You are misunderstanding what dir.listFiles() returns. It doesn't return all objects in the tree beneath dir. It only returns objects (files, directories, symlinks, etc) that are directly in dir.

The ".classpath" file suggests that you are looking at an Eclipse project directory, and Eclipse projects are normally configured with the Java files in a subdirectory such as "./src". I wouldn't expect to see any Java source code in the "." directory.

Can anyone explain to me why src isn't the current folder?"

Assuming that you are launching an application in Eclipse, then the current folder defaults to the project directory. You can change the default current directory via one of the panels in the Launcher configuration wizard.

we may can achieve this by using schema plugin also.

In helpers/schemaPlugin.js file

module.exports = function(schema) {

  var updateDate = function(next){
    var self = this;
    self.updated_at = new Date();
    if ( !self.created_at ) {
      self.created_at = now;
    }
    next()
  };
  // update date for bellow 4 methods
  schema.pre('save', updateDate)
    .pre('update', updateDate)
    .pre('findOneAndUpdate', updateDate)
    .pre('findByIdAndUpdate', updateDate);
};

and in models/ItemSchema.js file:

var mongoose = require('mongoose'),
  Schema   = mongoose.Schema,
  SchemaPlugin = require('../helpers/schemaPlugin');

var ItemSchema = new Schema({
  name    : { type: String, required: true, trim: true },
  created_at    : { type: Date },
  updated_at    : { type: Date }
});
ItemSchema.plugin(SchemaPlugin);
module.exports = mongoose.model('Item', ItemSchema);

Also an option which is quite similar to joaquin answer:

import random
from matplotlib import pyplot

#random data
x = [random.gauss(3,1) for _ in range(400)]
y = [random.gauss(4,2) for _ in range(400)]

#plot both histograms(range from -10 to 10), bins set to 100
pyplot.hist([x,y], bins= 100, range=[-10,10], alpha=0.5, label=['x', 'y'])
#plot legend
pyplot.legend(loc='upper right')
#show it
pyplot.show()

Gives the following output:

Yes you can. The default location for script files is data/db

If you put any script there you can call it as

load("myjstest.js")      // or 
load("/data/db/myjstest.js")

In addition to the other answers using HTML (either in Markdown or using the %%HTML magic:

If you need to specify the image height, this will not work:

<img src="image.png" height=50> <-- will not work

That is because the CSS styling in Jupyter uses height: auto per default for the img tags, which overrides the HTML height attribute. You need need to overwrite the CSS height attribute instead:

<img src="image.png" style="height:50px"> <-- works

WWW is an alias, so you don't need it if you want a domain. Here is my litllte function to get the real domain from a string

private string GetDomain(string url)
    {
        string[] split = url.Split('.');
        if (split.Length > 2)
            return split[split.Length - 2] + "." + split[split.Length - 1];
        else
            return url;

Using the code from my answer to a very similar question:

Sub DoSomething()
Dim Mainfram(4) As String
Dim cell As Excel.Range

Mainfram(0) = "apple"
Mainfram(1) = "pear"
Mainfram(2) = "orange"
Mainfram(3) = "fruit"

For Each cell In Selection
  If IsInArray(cell.Value, MainFram) Then
    Row(cell.Row).Style = "Accent1"
  End If
Next cell

End Sub

Function IsInArray(stringToBeFound As String, arr As Variant) As Boolean
  IsInArray = (UBound(Filter(arr, stringToBeFound)) > -1)
End Function

There's 3 satellites at least that you must be able to receive from of the 24-32 out there, and they each broadcast a time from a synchronized atomic clock. The differences in those times that you receive at any one time tell you how long the broadcast took to reach you, and thus where you are in relation to the satellites. So, it sort of reads from something, but it doesn't connect to that thing. Note that this doesn't tell you your orientation, many GPSes fake that (and speed) by interpolating data points.

If you don't count the cost of the receiver, it's a free service. Apparently there's higher resolution services out there that are restricted to military use. Those are likely a fixed cost for a license to decrypt the signals along with a confidentiality agreement.

Now your device may support GPS tracking, in which case it might communicate, say via GPRS, to a database which will store the location the device has found itself to be at, so that multiple devices may be tracked. That would require some kind of connection.

Maps are either stored on the device or received over a connection. Navigation is computed based on those maps' databases. These likely are a licensed item with a cost associated, though if you use a service like Google Maps they have the license with NAVTEQ and others.

The reason being you can not access protected member data through the instance of the class.

Reason why it is not allowed is explained in this blog

Update for iOS 10 (Swift 3)

In order to clear all local notifications in iOS 10 apps, you should use the following code:

import UserNotifications

...

if #available(iOS 10.0, *) {
    let center = UNUserNotificationCenter.current()
    center.removeAllPendingNotificationRequests() // To remove all pending notifications which are not delivered yet but scheduled.
    center.removeAllDeliveredNotifications() // To remove all delivered notifications
} else {
    UIApplication.shared.cancelAllLocalNotifications()
}

This code handles the clearing of local notifications for iOS 10.x and all preceding versions of iOS. You will need to import UserNotifications for the iOS 10.x code.

A really easy way is to simply call post() on your layout. This will run your code the next step, after your view has already been created.

YOUR_LAYOUT.post( new Runnable() {
    @Override
    public void run() {
        int width  = YOUR_LAYOUT.getMeasuredWidth();
        int height = YOUR_LAYOUT.getMeasuredHeight(); 
    }
});

Use callbacks. Something like this should work based on your sample code.

function someFunc() {

callAjaxfunc(function() {
    console.log('Pass2');
});

}

function callAjaxfunc(callback) {
    //All ajax calls called here
    onAjaxSuccess: function() {
        callback();
    };
    console.log('Pass1');    
}

This will print Pass1 immediately (assuming ajax request takes atleast a few microseconds), then print Pass2 when the onAjaxSuccess is executed.

To add on nathan gonzalez answer, please note you need to assign the replaced object after calling replace function since it is not a mutator function:

myString = myString.replace('username1','');

The pyplot functions you are calling, axhline() and axvline() draw lines that span a portion of the axis range, regardless of coordinates. The parameters xmin or ymin use value 0.0 as the minimum of the axis and 1.0 as the maximum of the axis.

Instead, use plt.plot((x1, x2), (y1, y2), 'k-') to draw a line from the point (x1, y1) to the point (x2, y2) in color k. See pyplot.plot.

Just ran into this problem myself. OSx Lion hides scrollbars while not in use to make it seem more "slick", but at the same time the issue you addressed comes up: people sometimes cannot see whether a div has a scroll feature or not.

The fix: In your css include -

  -webkit-appearance: none;
  width: 7px;
}

::-webkit-scrollbar-thumb {
  border-radius: 4px;
  background-color: rgba(0, 0, 0, .5);
  box-shadow: 0 0 1px rgba(255, 255, 255, .5);
}

Oftentimes in Ruby, you don't actually care what the object's class is, per se, you just care that it responds to a certain method. This is known as Duck Typing and you'll see it in all sorts of Ruby codebases.

So in many (if not most) cases, its best to use Duck Typing using #respond_to?(method):

object.respond_to?(:to_i)

Here is a script you can use to merge your master branch into your current branch.

The script does the following:

• Switches to the master branch
• Pulls the master branch
• Switches back to your current branch
• Merges the master branch into your current branch

Save this code as a batch file (.bat) and place the script anywhere in your repository. Then click on it to run it and you are set.

:: This batch file pulls current master and merges into current branch

@echo off

:: Option to use the batch file outside the repo and pass the repo path as an arg
set repoPath=%1
cd %repoPath%

FOR /F "tokens=*" %%g IN ('git rev-parse --abbrev-ref HEAD') do (SET currentBranch=%%g)

echo current branch is %currentBranch%
echo switching to master
git checkout master
echo.
echo pulling origin master
git pull origin master
echo.
echo switching back to %currentBranch%
git checkout %currentBranch%
echo.
echo attemting merge master into %currentBranch%
git merge master
echo.
echo script finished successfully

You have to add a condition in your componentDidUpdate method.

The example is using fast-deep-equal to compare the objects.

import equal from 'fast-deep-equal'

...

constructor(){
  this.updateUser = this.updateUser.bind(this);
}  

componentDidMount() {
  this.updateUser();
}

componentDidUpdate(prevProps) {
  if(!equal(this.props.user, prevProps.user)) // Check if it's a new user, you can also use some unique property, like the ID  (this.props.user.id !== prevProps.user.id)
  {
    this.updateUser();
  }
} 

updateUser() {
  if (this.props.isManager) {
    this.props.dispatch(actions.fetchAllSites())
  } else {
    const currentUserId = this.props.user.get('id')
    this.props.dispatch(actions.fetchUsersSites(currentUserId))
  }  
}

Using Hooks (React 16.8.0+)

import React, { useEffect } from 'react';

const SitesTableContainer = ({
  user,
  isManager,
  dispatch,
  sites,
}) => {
  useEffect(() => {
    if(isManager) {
      dispatch(actions.fetchAllSites())
    } else {
      const currentUserId = user.get('id')
      dispatch(actions.fetchUsersSites(currentUserId))
    }
  }, [user]); 

  return (
    return <SitesTable sites={sites}/>
  )

}

If the prop you are comparing is an object or an array, you should use useDeepCompareEffect instead of useEffect.

Setting a br tag to display: none is helpful, but then you can end up with WordsRunTogether. I've found it more helpful to instead replace it with a space character, like so:

HTML:

<h1>
    Breaking<br />News:<br />BR<br />Considered<br />Harmful!
</h1>

CSS:

@media (min-device-width: 1281px){
    h1 br {content: ' ';}
    h1 br:after {content: ' ';}
}

I ran into a similar issue with getting SSL to work on a port other than port 443. In my case I had a bundle certificate as well as a certificate and a key. The bundle certificate is a file that holds multiple certificates, node requires that you break those certificates into separate elements of an array.

    var express = require('express');
    var https = require('https');
    var fs = require('fs');

    var options = {
      ca: [fs.readFileSync(PATH_TO_BUNDLE_CERT_1), fs.readFileSync(PATH_TO_BUNDLE_CERT_2)],
      cert: fs.readFileSync(PATH_TO_CERT),
      key: fs.readFileSync(PATH_TO_KEY)
    };

    app = express()

    app.get('/', function(req,res) {
        res.send('hello');
    });

    var server = https.createServer(options, app);

    server.listen(8001, function(){
        console.log("server running at https://IP_ADDRESS:8001/")
    });

In app.js you need to specify https and create the server accordingly. Also, make sure that the port you're trying to use is actually allowing inbound traffic.

Yes, the list type is a good approximation. You can use names() on your list to set and retrieve the 'keys':

> foo <- vector(mode="list", length=3)
> names(foo) <- c("tic", "tac", "toe")
> foo[[1]] <- 12; foo[[2]] <- 22; foo[[3]] <- 33
> foo
$tic
[1] 12

$tac
[1] 22

$toe
[1] 33

> names(foo)
[1] "tic" "tac" "toe"
> 

This works in many popular languages like JavaScript and Ruby, why not in Python?

>>> ['a', 'b', 'c'].join('')
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
AttributeError: 'list' object has no attribute 'join'

Strange enough, in Python the join method is on the str class:

# this is the Python way
"".join(['a','b','c','d'])

Why join is not a method in the list object like in JavaScript or other popular script languages? It is one example of how the Python community thinks. Since join is returning a string, it should be placed in the string class, not on the list class, so the str.join(list) method means: join the list into a new string using str as a separator (in this case str is an empty string).

Somehow I got to love this way of thinking after a while. I can complain about a lot of things in Python design, but not about its coherence.

Use some JPA 2 implementation: it adds a @ElementCollection annotation, similar to the Hibernate one, that does exactly what you need. There's one example here.

Edit

As mentioned in the comments below, the correct JPA 2 implementation is

javax.persistence.ElementCollection

@ElementCollection
Map<Key, Value> collection;

See: http://docs.oracle.com/javaee/6/api/javax/persistence/ElementCollection.html

it's in there by default. It's the id field.

A message has a header part and a message body separated by a blank line. The blank line is ALWAYS needed even if there is no message body. The header starts with a command and has additional lines of key value pairs separated by a colon and a space. If there is a message body, it can be anything you want it to be.

Lines in the header and the blank line at the end of the header must end with a carraige return and linefeed pair (see HTTP header line break style) so that's why those lines have \r\n at the end.

A URL has the form of http://host:port/path?query_string

There are two main ways of submitting a request to a website:

• GET: The query string is optional but, if specified, must be reasonably short. Because of this the header could just be the GET command and nothing else. A sample message could be:

  GET /path?query_string HTTP/1.0\r\n
  \r\n
  

• POST: What would normally be in the query string is in the body of the message instead. Because of this the header needs to include the Content-Type: and Content-Length: attributes as well as the POST command. A sample message could be:

  POST /path HTTP/1.0\r\n
  Content-Type: text/plain\r\n
  Content-Length: 12\r\n
  \r\n
  query_string
  

So, to answer your question: if the URL you are interested in POSTing to is http://api.somesite.com/apikey=ARG1&command=ARG2 then there is no body or query string and, consequently, no reason to POST because there is nothing to put in the body of the message and so nothing to put in the Content-Type: and Content-Length:

I guess you could POST if you really wanted to. In that case your message would look like:

POST /apikey=ARG1&command=ARG2 HTTP/1.0\r\n
\r\n

So to send the message the C program needs to:

• create a socket
• lookup the IP address
• open the socket
• send the request
• wait for the response
• close the socket

The send and receive calls won't necessarily send/receive ALL the data you give them - they will return the number of bytes actually sent/received. It is up to you to call them in a loop and send/receive the remainder of the message.

What I did not do in this sample is any sort of real error checking - when something fails I just exit the program. Let me know if it works for you:

#include <stdio.h> /* printf, sprintf */
#include <stdlib.h> /* exit */
#include <unistd.h> /* read, write, close */
#include <string.h> /* memcpy, memset */

Like the other answer pointed out, 4096 bytes is not a very big response. I picked that number at random assuming that the response to your request would be short. If it can be big you have two choices:

• read the Content-Length: header from the response and then dynamically allocate enough memory to hold the whole response.
• write the response to a file as the pieces arrive

Additional information to answer the question asked in the comments:

What if you want to POST data in the body of the message? Then you do need to include the Content-Type: and Content-Length: headers. The Content-Length: is the actual length of everything after the blank line that separates the header from the body.

Here is a sample that takes the following command line arguments:

• host
• port
• command (GET or POST)
• path (not including the query data)
• query data (put into the query string for GET and into the body for POST)
• list of headers (Content-Length: is automatic if using POST)

So, for the original question you would run:

a.out api.somesite.com 80 GET "/apikey=ARG1&command=ARG2"

And for the question asked in the comments you would run:

a.out api.somesite.com 80 POST / "name=ARG1&value=ARG2" "Content-Type: application/x-www-form-urlencoded"

This worked for me, including recursively into submodules (perhaps that's why your -f didn't work, cause you changed a submodule inside the submodule):

git submodule update -f --recursive

Dynamic List Loosely Typed - Deserialize and read the values

// First serializing
dynamic collection = new { stud = stud_datatable }; // The stud_datable is the list or data table
string jsonString = JsonConvert.SerializeObject(collection);


// Second Deserializing
dynamic StudList = JsonConvert.DeserializeObject(jsonString);

var stud = StudList.stud;
foreach (var detail in stud)
{
    var Address = detail["stud_address"]; // Access Address data;
}

1. To be clear: The option "Value for Edit Top Rows command" has nothing to do with the fact if a result set is editable or not. It is just a way to limit the result set.

2. Editing the result set of a query based on one and only one table is obviously always possible.

3. The result set of a query based on more than one table is under following condition possible: You can edit the fields in the result set at once if they belong to one and only one based table in the query! If the fields are Primary Key, then you have to fulfill refresh/"Execute SQL" (Ctrl+R) after each row update, in order to be able to edit a row next time. If the fields are not Primary Key, then you do not need to fulfill refresh/"Execute SQL" (Ctrl+R).

I have tested it on SQL Server 2008 - 2016!

Twitter Bootstrap assigns the active class to the li element that represents the active tab:

$("ul#sampleTabs li.active")

An alternative is to bind the shown event of each tab, and save the active tab:

var activeTab = null;
$('a[data-toggle="tab"]').on('shown', function (e) {
  activeTab = e.target;
})

You want to use coalesce():

where coalesce(email, email2) like '%[email protected]%'

If you want to handle empty strings ('') versus NULL, a case works:

where (case when email is NULL or email = '' then email2 else email end) like '%[email protected]%'

And, if you are worried about the string really being just spaces:

where (case when email is NULL or ltrim(email) = '' then email2 else email end) like '%[email protected]%'

As an aside, the sample if statement is really saying "If email starts with a number larger than 0". This is because the comparison is to 0, a number. MySQL implicitly tries to convert the string to a number. So, '[email protected]' would fail, because the string would convert as 0. As would '[email protected]'. But, '[email protected]' and '[email protected]' would succeed.

You're passing a type as an argument, not an object. You need to do characterSelection(screen, test); where test is of type SelectionneNonSelectionne.

Use "target" attribute and remove the 'compiler' attribute. See here. So it should go something like this:

<target name="compile">
  <javac target="1.5" srcdir=.../>
</target>

Hope this helps

A combination of floating and absolute positioning does the work for me. I was attempting to place the send time of a message at the bottom-right corner of the speech bubble. The time should never overlap the message body and it will not inflate the bubble unless it's really necessary.

The solution works like this:

1. there're two spans with identical text;
2. one is floated but invisible;
3. the other is absolutely positioned to the corner;

The purpose of the invisible floated one is to ensure space for the visible one.

.speech-bubble {
  font-size: 16px;
  max-width: 240px;
  margin: 10px;
  display: inline-block;
  background-color: #ccc;
  border-radius: 5px;
  padding: 5px;
  position: relative;
}

.inline-time {
  float: right;
  padding-left: 10px;
  color: red;
}

.giant-text {
  font-size: 36px;
}

.tremendous-giant-text {
  font-size: 72px;
}

.absolute-time {
  position: absolute;
  color: green;
  right: 5px;
  bottom: 5px;
}

.hidden {
  visibility: hidden;
}

<ul>
  <li>
    <span class='speech-bubble'>
      This text is supposed to wrap the time &lt;span&gt; which always seats at the corner of this bubble.
      <span class='inline-time'>13:55</span>
    </span>
  </li>
  
  <li>
    <span class='speech-bubble'>
      Absolute positioning doesn't work because it doesn't care if the two pieces of text overlap. We want to float.
      <span class='inline-time'>13:55</span>
    </span>
  </li>

  <li>
    <span class='speech-bubble'>
      Easy, uh?
      <span class='inline-time'>13:55</span>
    </span>
  </li>
  
  <li>
    <span class='speech-bubble'>
      Well, not <span class='giant-text'>THAT</span>
      easy
      <span class='inline-time'>13:56</span>
    </span>
  </li>
  
  <li>
    <span class='speech-bubble'>
      <span class='tremendous-giant-text'>See?</span>
      <span class='inline-time'>13:56</span>
    </span>
  </li>
  
  <li>
    <span class='speech-bubble'>
      The problem is, we can't tell the span to float to right AND bottom...
      <span class='inline-time'>13:56</span>
    </span>
  </li>
  
  <li>
    <span class='speech-bubble'>
      We can combinate float and absolute: use floated span to reserve space (the bubble will be inflated if necessary) so that the absoluted span is safe to go.
      <span class='inline-time'>13:56</span>
    </span>
  </li>
  
  <li>
    <span class='speech-bubble'>
      <span class='tremendous-giant-text'>See?</span>
      <span class='inline-time'>13:56</span>
      <span class='absolute-time'>13:56</span>
    </span>
  </li>
  
  <li>
    <span class='speech-bubble'>
      Make the floated span invisible.
      <span class='inline-time'>13:56</span>
    </span>
  </li>
  
  <li>
    <span class='speech-bubble'>
      <span class='tremendous-giant-text'>See?</span>
      <span class='inline-time hidden'>13:56</span>
      <span class='absolute-time'>13:56</span>
    </span>

  <li>
    <span class='speech-bubble'>
      The giant text here is to simulate images which are common in a typical chat app.

Assuming that "a" and "b" are bean properties

You may look at JSF EL operators

Empty is a subset of any string.

Think of them as what is between every two characters.

Kind of the way there are an infinite number of points on any sized line...

(Hmm... I wonder what I would get if I used calculus to concatenate an infinite number of empty strings)

Note that "".equals("") only though.

So this has happened a couple of times just recently. As a .Net dev, using VisualStudio I changed my build name from SomeThing to Something as the DLL name but this does not change the .csproj file which stays SomeThing.csproj

The Dockerfile uses linux case-sensitive filenames, so the newly autogenerated Dockerfile was trying to copy Something.csproj which it couldn't find. So manually renaming that file (making it lowercase) got it all working

But...here's a cautionary warning. This filename change on my Windows laptop does not get picked up by Git so the repo source was still SomeThing.csproj on the repo and during the CI/CD process, the Docker build failed for the same reasons...

I had to change the filename directly as a commit on the repo....nasty little workaround but got me going

tl;dr If on Windows O/S check for filename case sensitivity and be aware local file renames do not get picked up as Git change so make sure your repo is also modified if using CI/CD

Hands down the easiest way to parse a HTML table is to use pandas.read_html() - it accepts both URLs and HTML.

import pandas as pd
url = r'https://en.wikipedia.org/wiki/List_of_S%26P_500_companies'
tables = pd.read_html(url) # Returns list of all tables on page
sp500_table = tables[0] # Select table of interest

Only downside is that read_html() doesn't preserve hyperlinks.

Just start from there that in CSS, if you repeat 2 values or more, always last one gets applied, unless using !important tag, but at the same time avoid using !important as much as you can, so in your case that's the problem, so the second transform override the first one in this case...

So how you can do what you want then?...

Don't worry, transform accepts multiple values at the same time... So this code below will work:

li:nth-child(2) {
  transform: rotate(15deg) translate(-20px, 0px); //multiple
}

If you like to play around with transform run the iframe from MDN below:

<iframe src="https://interactive-examples.mdn.mozilla.net/pages/css/transform.html" class="interactive  " width="100%" frameborder="0" height="250"></iframe>

Look at the link below for more info:

<< CSS transform >>

Very possibly it's getting converted to a modified Base64, where the + and / characters are changed to - and _. See http://en.wikipedia.org/wiki/Base64#Implementations_and_history

If that's the case, you need to change it back:

string converted = base64String.Replace('-', '+');
converted = converted.Replace('_', '/');

You can reverse the rows in an even simpler way:

df[::-1]

This may not have been the OP's problem, but I had the same problem and solved it by flushing then disabling Supercache on my cpanel. Perhaps some other newbies like myself won't know that many hosting providers cache CSS and some other static files, and these cached old versions of CSS files will persist in the cloud for hours after you edit the file on your server. If your site serves up old versions of CSS files after you edit them, and you're certain you've cleared your browser cache, and you don't know whether your host is caching stuff, check that first before you try any other more complicated suggestions.

To mark as obsolete with a warning:

[Obsolete]
private static void SomeMethod()

You get a warning when you use it:

And with IntelliSense:

If you want a message:

[Obsolete("My message")]
private static void SomeMethod()

Here's the IntelliSense tool tip:

Finally if you want the usage to be flagged as an error:

[Obsolete("My message", true)]
private static void SomeMethod()

When used this is what you get:

Note: Use the message to tell people what they should use instead, not why it is obsolete.

I recently came across this requirement myself, and I decided to implement an ActionFilter to handle this.

public class ArrayInputAttribute : ActionFilterAttribute
{
    private readonly string _parameterName;

    public ArrayInputAttribute(string parameterName)
    {
        _parameterName = parameterName;
        Separator = ',';
    }

    public override void OnActionExecuting(HttpActionContext actionContext)
    {
        if (actionContext.ActionArguments.ContainsKey(_parameterName))
        {
            string parameters = string.Empty;
            if (actionContext.ControllerContext.RouteData.Values.ContainsKey(_parameterName))
                parameters = (string) actionContext.ControllerContext.RouteData.Values[_parameterName];
            else if (actionContext.ControllerContext.Request.RequestUri.ParseQueryString()[_parameterName] != null)
                parameters = actionContext.ControllerContext.Request.RequestUri.ParseQueryString()[_parameterName];

            actionContext.ActionArguments[_parameterName] = parameters.Split(Separator).Select(int.Parse).ToArray();
        }
    }

    public char Separator { get; set; }
}

I am applying it like so (note that I used 'id', not 'ids', as that is how it is specified in my route):

[ArrayInput("id", Separator = ';')]
public IEnumerable<Measure> Get(int[] id)
{
    return id.Select(i => GetData(i));
}

And the public url would be:

/api/Data/1;2;3;4

You may have to refactor this to meet your specific needs.

Add overflow: auto; to the style and the two finger scroll should work.
