You can use .htaccess or server directives to deny access to favicon.ico, but the server will send an access denied reply to the browser and this still slows page access.

You can stop the browser requesting favicon.ico when a user returns to your site, by getting it to stay in the browser cache.

First, provide a small favicon.ico image, could be blank, but as small as possible. I made a black and white one under 200 bytes. Then, using .htaccess or server directives, set the file Expires header a month or two in the future. When the same user comes back to your site it will be loaded from the browser cache and no request will go to your site. No more 404's in the server logs too.

If you have control over a complete Apache server or maybe a virtual server you can do this:-

If the server document root is say /var/www/html then add this to /etc/httpd/conf/httpd.conf:-

Alias /favicon.ico "/var/www/html/favicon.ico"
<Directory "/var/www/html">
    <Files favicon.ico>
       ExpiresActive On
       ExpiresDefault "access plus 1 month"
    </Files>
</Directory>

Then a single favicon.ico will work for all the virtual hosted sites since you are aliasing it. It will be drawn from the browser cache for a month after the users visit.

For .htaccess this is reported to work (not checked by me):-

AddType image/x-icon .ico
ExpiresActive On
ExpiresByType image/x-icon "access plus 1 month"

I check if a number is prime or not with the following code( of course using sqrt ):

bool IsPrime(const unsigned int x)
{
  const unsigned int TOP
  = static_cast<int>(
      std::sqrt( static_cast<double>( x ) )
    ) + 1;

  for ( int i=2; i != TOP; ++i )
  {
    if (x % i == 0) return false;
  }
  return true;
}

I use this method to determine the primes:

#include <iostream>

using std::cout;
using std::cin;
using std::endl;

#include <cmath>

void initialize( unsigned int *, const unsigned int );
void show_list( const unsigned int *, const unsigned int );
void criba( unsigned int *, const unsigned int );
void setItem ( unsigned int *, const unsigned int, const unsigned int );

bool IsPrime(const unsigned int x)
{
  const unsigned int TOP
  = static_cast<int>(
      std::sqrt( static_cast<double>( x ) )
    ) + 1;

  for ( int i=2; i != TOP; ++i )
  {
    if (x % i == 0) return false;
  }
  return true;
}

int main()
{

    unsigned int *l;
    unsigned int n;

    cout << "Ingrese tope de criba" << endl;
    cin >> n;

    l = new unsigned int[n];

    initialize( l, n );

    cout << "Esta es la lista" << endl;
    show_list( l, n );

    criba( l, n );  

    cout << "Estos son los primos" << endl;
    show_list( l, n );
}

void initialize( unsigned int *l, const unsigned int n)
{
    for( int i = 0; i < n - 1; i++ )
        *( l + i ) = i + 2;
}

void show_list( const unsigned int *l, const unsigned int n)
{
    for( int i = 0; i < n - 1; i++ )
    {
        if( *( l + i ) != 0)
            cout << l[i] << " - ";
    }
    cout << endl;
}

void setItem( unsigned int *l, const unsigned int n, const unsigned int p)
{
    unsigned int i = 2;
    while( p * i <= n)
    {
        *( l + (i * p - 2) ) = 0;
        i++;
    }
}

void criba( unsigned int *l, const unsigned int n)
{
    for( int i = 0;  i * i <= n ; i++ )
     if( IsPrime ( *( l + i) ) )
        setItem( l, n, *(l + i) );      
}

I encountered this error with the Eclipse 4.10 installer. We had failed to complete the install correctly due to platform security settings and attempted to uninstall but had to do it by hand since no uninstaller was introduced during the failed install. We suspected this corrupted the end result - even after re-installing.

The solution was to use the JVM to launch Eclipse and bypass the launcher executable entirely. The following command successfully launches Eclipse 4.10 (some parameters will change based on the version of Eclipse):

%JDK190%\bin\javaw.exe -jar C:\<fully_qualified_path_to_eclipse>\Eclipse410\plugins\org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar -clean -showsplash

After using this command/shortcut to launch Eclipse we had no further errors with Eclipse itself but we weren't able to use the EXE launcher in the future. Even after a year of using this version, the launcher continues to display this same error.

To be clear, you'll have to modify your javaw.exe command to match your system specifications on MS Windows.

This is called string interpolation; it doesn't exist as such in Java.

One approach is to use String.format:

String string = String.format("A string %s", aVariable);

Another approach is to use a templating library such as Velocity or FreeMarker.

Here's a more interesting implementation of multi line lambdas. It's not possible to achieve because of how python use indents as a way to structure code.

But luckily for us, indent formatting can be disabled using arrays and parenthesis.

As some already pointed out, you can write your code as such:

lambda args: (expr1, expr2,... exprN)

In theory if you're guaranteed to have evaluation from left to right it would work but you still lose values being passed from one expression to an other.

One way to achieve that which is a bit more verbose is to have

lambda args: [lambda1, lambda2, ..., lambdaN]

Where each lambda receives arguments from the previous one.

def let(*funcs):
    def wrap(args):
        result = args                                                                                                                                                                                                                         
        for func in funcs:
            if not isinstance(result, tuple):
                result = (result,)
            result = func(*result)
        return result
    return wrap

This method let you write something that is a bit lisp/scheme like.

So you can write things like this:

let(lambda x, y: x+y)((1, 2))

A more complex method could be use to compute the hypotenuse

lst = [(1,2), (2,3)]
result = map(let(
  lambda x, y: (x**2, y**2),
  lambda x, y: (x + y) ** (1/2)
), lst)

This will return a list of scalar numbers so it can be used to reduce multiple values to one.

Having that many lambda is certainly not going to be very efficient but if you're constrained it can be a good way to get something done quickly then rewrite it as an actual function later.

Just a clarification on the answer given by Bkkbrad.

I tried this suggestion and it did not work for me.

For example,

split('aa|bb','\\|')

produced:

["","a","a","|","b","b",""]

But,

split('aa|bb','[|]')

produced the desired result:

["aa","bb"]

Including the metacharacter '|' inside the square brackets causes it to be interpreted literally, as intended, rather than as a metacharacter.

For elaboration of this behaviour of regexp, see: http://www.regular-expressions.info/charclass.html

No. But there are other options out there like Overlib, and jQuery that allow you this freedom.

• jTip : http://www.codylindley.com/blogstuff/js/jtip/
• jQuery Tooltip : https://jqueryui.com/tooltip/

Personally, I would suggest jQuery as the route to take. It's typically very unobtrusive, and requires no additional setup in the markup of your site (with the exception of adding the jquery script tag in your <head>).

As MusiGenesis put so nicely, in most databases:

schema : database : table :: floor plan : house : room

But, in Oracle it may be easier to think of:

schema : database : table :: owner : house : room

Adding to @Dima's answer, if you're using maven to build your package, you can tell it to set your WAR file name to ROOT in pom.xml:

<build>
    <finalName>ROOT</finalName>
</build>

By default, tomcat will deploy ROOT.war webapp into root context (/).

If you’re concerned about the file size of a PNG, you can use an SVG mask to create a transparent JPEG. Here is an example I put together.

Here is a Kotlin extension to get the correct position even if your group contains a TextView or any non-RadioButton.

fun RadioGroup.getCheckedRadioButtonPosition(): Int {
    val radioButtonId = checkedRadioButtonId
    return children.filter { it is RadioButton }
        .mapIndexed { index: Int, view: View ->
            index to view
        }.firstOrNull {
            it.second.id == radioButtonId
        }?.first ?: -1
}

To check if a directory named "Folder" exists use:

QDir("Folder").exists();

To create a new folder named "MyFolder" use:

QDir().mkdir("MyFolder");

Also You Can Use Server.Execute

You can use this package from_css_color to get Color out of a hex string. It supports both three and six digit RGB hex notation.

Color color = fromCSSColor('#ff00aa')

For optimisation sake create Color instance once for each color and store it somewhere for later usage.

What I did was to create a canvas element that I then position in front of the image map. Then, whenever an area is moused-over, I call a func that gets the coord string for that shape and the shape-type. If it's a poly I use the coords to draw an outline on the canvas. If it's a rect I draw a rect outline. You could easily add code to deal with circles.

You could also set the opacity of the canvas to less than 100% before filling the poly/rect/circle. You could also change the reliance on a global for the canvas's context - this would mean you could deal with more than 1 image-map on the same page.

// draws a line from each co-ord pair to the next - assumes starting point needs to be repeated as ending point.

    var mCoords = coOrdStr.split(',');
    var i, n;

DateTime inherits its equals method from AbstractInstant. It is implemented as such

public boolean equals(Object readableInstant) {     // must be to fulfil ReadableInstant contract     if (this == readableInstant) {         return true;     }     if (readableInstant instanceof ReadableInstant == false) {         return false;     }     ReadableInstant otherInstant = (ReadableInstant) readableInstant;     return         getMillis() == otherInstant.getMillis() &&         FieldUtils.equals(getChronology(), otherInstant.getChronology()); } 

Notice the last line comparing chronology. It's possible your instances' chronologies are different.

This function is most fast:

CREATE FUNCTION dbo.F_ExtractSubString
(
  @String VARCHAR(MAX),
  @NroSubString INT,
  @Separator VARCHAR(5)
)
RETURNS VARCHAR(MAX) AS
BEGIN
    DECLARE @St INT = 0, @End INT = 0, @Ret VARCHAR(MAX)
    SET @String = @String + @Separator
    WHILE CHARINDEX(@Separator, @String, @End + 1) > 0 AND @NroSubString > 0
    BEGIN
        SET @St = @End + 1
        SET @End = CHARINDEX(@Separator, @String, @End + 1)
        SET @NroSubString = @NroSubString - 1
    END
    IF @NroSubString > 0
        SET @Ret = ''
    ELSE
        SET @Ret = SUBSTRING(@String, @St, @End - @St)
    RETURN @Ret
END
GO

Example usage:

SELECT dbo.F_ExtractSubString(COLUMN, 1, ', '),
       dbo.F_ExtractSubString(COLUMN, 2, ', '),
       dbo.F_ExtractSubString(COLUMN, 3, ', ')
FROM   TABLE

Not with CSS, but you can emulate and extend / customize the desired behavior with JavaScript.

You can use this:

    Range("MyTable[#Data]").Rows.Count

You have to distinguish between a table which has either one row of data or no data, as the previous code will return "1" for both cases. Use this to test for an empty table:

    If WorksheetFunction.CountA(Range("MyTable[#Data]"))

For django 1.10 you may have to do python manage.py makemigrations appname.

make mylist into a List<MyObject>, is one option

If you are looking to create an instant messenger for Android, this code should get you started somewhere.

Excerpt from the source :

This is a simple IM application runs on Android, application makes http request to a server, implemented in php and mysql, to authenticate, to register and to get the other friends' status and data, then it communicates with other applications in other devices by socket interface.

EDIT : Just found this! Maybe it's not related to WhatsApp. But you can use the source to understand how chat applications are programmed.

There is a website called Scringo. These awesome people provide their own SDK which you can integrate in your existing application to exploit cool features like radaring, chatting, feedback, etc. So if you are looking to integrate chat in application, you could just use their SDK. And did I say the best part? It's free!

*UPDATE : * Scringo services will be closed down on 15 February, 2015.

It's not possible with CSS3. There is a proposed CSS4 selector, $, to do just that, which could look like this (Selecting the li element):

ul $li ul.sub { ... }

See the list of CSS4 Selectors here.

As an alternative, with jQuery, a one-liner you could make use of would be this:

$('ul li:has(ul.sub)').addClass('has_sub');

You could then go ahead and style the li.has_sub in your CSS.

    Array.prototype.moveUp = function (value, by) {
        var index = this.indexOf(value),
            newPos = index - (by || 1);

            throw new Error("Element not found in array");

        if (newPos < 0)
            newPos = 0;

        this.splice(index, 1);
        this.splice(newPos, 0, value);
    };

    Array.prototype.moveDown = function (value, by) {

            newPos = index + (by || 1);

        if (index === -1)
            throw new Error("Element not found in array");

        if (newPos >= this.length)
            newPos = this.length;

        this.splice(index, 1);
        this.splice(newPos, 0, value);
    };

If you're debugging something and just want to see what's in there for your the print_f function formats the output nicely.

class Second:
    def __init__(self, data):
        self.data = data

class First:
    def SecondClass(self, data):
        return Second(data)

FirstClass = First()
SecondClass = FirstClass.SecondClass('now you see me')
print SecondClass.data

So after having the same issue with not being able to adjust height in text box, Width adjustment is fine but height never adjusted with the above suggestions (at least for me), I was finally able to take make it happen. As mentioned above, the issue appeared to be centered around a default font size setting in my text box and the behavior of the text box auto sizing around it. The default font size was tiny. Hence why trying to force the height or even turn off autosizing failed to fix the issue for me.

Set the Font properties to the size of your liking and then height change will kick in around the FONT size, automatically. You can still manually set your text box width. Below is snippet I added that worked for me.

    $textBox = New-Object System.Windows.Forms.TextBox
$textBox.Location = New-Object System.Drawing.Point(60,300)
$textBox.Size = New-Object System.Drawing.Size(600,80)
$textBox.Font = New-Object System.Drawing.Font("Times New Roman",18,[System.Drawing.FontStyle]::Regular)
$textBox.Form.Font = $textbox.Font

Please note the Height value in '$textBox.Size = New-Object System.Drawing.Size(600,80)' is being ignored and the FONT size is actually controlling the height of the text box by autosizing around that font size.

Simple guys .... but remember each byte is random between 0 and 255 which for a random string will be fine. Also remember you'll have two characters to represent each byte.

$str = bin2hex(random_bytes(32));  // 64 character string returned

Starting with API15, you can use also callOnClick() that directly call attached view OnClickListener. Unlike performClick(), this only calls the listener, and does not do any associated clicking actions like reporting an accessibility event.

try by Adding following onClientClick event.

OnClientClick="aspnetForm.target ='_blank';"

so on click it will call Javascript function an will open respective link in News tab.

<asp:LinkButton id="lbnkVidTtile1" OnClientClick="aspnetForm.target ='_blank';" runat="Server" CssClass="bodytext" Text='<%# Eval("newvideotitle") %>'  />

Most of the answers seem focused around converting the date from a string to time. It seems you're mostly thinking about getting the date into the '5 days ago' format, etc.. right?

This is how I'd go about doing that:

$time = strtotime('2010-04-28 17:25:43');

echo 'event happened '.humanTiming($time).' ago';

function humanTiming ($time)
{

    $time = time() - $time; // to get the time since that moment
    $time = ($time<1)? 1 : $time;
    $tokens = array (
        31536000 => 'year',
        2592000 => 'month',
        604800 => 'week',
        86400 => 'day',
        3600 => 'hour',
        60 => 'minute',
        1 => 'second'
    );

    foreach ($tokens as $unit => $text) {
        if ($time < $unit) continue;
        $numberOfUnits = floor($time / $unit);
        return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'');
    }

}

I haven't tested that, but it should work.

The result would look like

event happened 4 days ago

or

event happened 1 minute ago

cheers

For me just worked iisreset (run cmd as administrator -> iisreset). Maybe somebody could give it a try.

On a MAC, you need to use nm *.o | c++filt, as there is no -C option in nm.

how can scrapy be used to scrape this dynamic data so that I can use it?

I wonder why no one has posted the solution using Scrapy only.

Check out the blog post from Scrapy team SCRAPING INFINITE SCROLLING PAGES . The example scraps http://spidyquotes.herokuapp.com/scroll website which uses infinite scrolling.

The idea is to use Developer Tools of your browser and notice the AJAX requests, then based on that information create the requests for Scrapy.

import json
import scrapy


class SpidyQuotesSpider(scrapy.Spider):
    name = 'spidyquotes'
    quotes_base_url = 'http://spidyquotes.herokuapp.com/api/quotes?page=%s'
    start_urls = [quotes_base_url % 1]
    download_delay = 1.5

    def parse(self, response):
        data = json.loads(response.body)
        for item in data.get('quotes', []):
            yield {
                'text': item.get('text'),
                'author': item.get('author', {}).get('name'),
                'tags': item.get('tags'),
            }
        if data['has_next']:
            next_page = data['page'] + 1
            yield scrapy.Request(self.quotes_base_url % next_page)

Ok after trying soo many things, the correct solution is ...

you need to set DEBUG = 'FALSE' not False or FALSE, but 'FALSE' with ''

Use notepad++, go to edit -> EOL conversion -> change from CRLF to LF.

C++11 lambdas can't be templated as stated in other answers but decltype() seems to help when using a lambda within a templated class or function.

#include <iostream>
#include <string>

using namespace std;

template<typename T>
void boring_template_fn(T t){
    auto identity = [](decltype(t) t){ return t;};
    std::cout << identity(t) << std::endl;
}

int main(int argc, char *argv[]) {
    std::string s("My string");
    boring_template_fn(s);
    boring_template_fn(1024);
    boring_template_fn(true);
}

Prints:

My string
1024
1

I've found this technique is helps when working with templated code but realize it still means lambdas themselves can't be templated.

OMG, I tried to find a simple solution to this for hours. I knew the code was simple but no one provided me what I wanted. So finally got to work on some example code and made something simple that anyone can use no JQuery required. Simple javascript and css and html. In order for the animation to work you have to set the height and width or the animation wont work. Found that out the hard way.

<script>
        function dostuff() {
            if (document.getElementById('MyBox').style.height == "0px") {

                document.getElementById('MyBox').setAttribute("style", "background-color: #45CEE0; height: 200px; width: 200px; transition: all 2s ease;"); 
            }
            else {
                document.getElementById('MyBox').setAttribute("style", "background-color: #45CEE0; height: 0px; width: 0px; transition: all 2s ease;"); 
             }
        }
    </script>
    <div id="MyBox" style="height: 0px; width: 0px;">
    </div>

    <input type="button" id="buttontest" onclick="dostuff()" value="Click Me">

Vin's answer worked great for me. Here is the same solution for C# developers using Xamarin.iOS/MonoTouch:

var navigationBar = NavigationController.NavigationBar; //or another reference
navigationBar.BarTintColor = UIColor.Blue;
navigationBar.TintColor = UIColor.White;
navigationBar.SetTitleTextAttributes(new UITextAttributes() { TextColor = UIColor.White });
navigationBar.Translucent = false;

To concatenate multiple strings into a single string, separated by another character, there are a couple of ways.

The nicest I have seen is using the join method on an array:

fn main() {
    let a = "Hello";
    let b = "world";
    let result = [a, b].join("\n");

    print!("{}", result);
}

Depending on your use case you might also prefer more control:

fn main() {
    let a = "Hello";
    let b = "world";
    let result = format!("{}\n{}", a, b);

    print!("{}", result);
}

There are some more manual ways I have seen, some avoiding one or two allocations here and there. For readability purposes I find the above two to be sufficient.

You need to import FormsModule in your @NgModule Decorator, @NgModule is present in your moduleName.module.ts file.

import { FormsModule } from '@angular/forms';
@NgModule({
   imports: [
      BrowserModule,
      FormsModule
   ],
   declarations: [ AppComponent ],
   bootstrap: [ AppComponent ]
 })

Bind Method

A bind implementation might look something like so:

Function.prototype.bind = function () {
  const self = this;
  const args = [...arguments];
  const context = args.shift();

  return function () {
    return self.apply(context, args.concat([...arguments]));
  };
};

The bind function can take any number of arguments and return a new function.

The new function will call the original function using the JS Function.prototype.apply method.
The apply method will use the first argument passed to the target function as its context (this), and the second array argument of the apply method will be a combination of the rest of the arguments from the target function, concat with the arguments used to call the return function (in that order).

An example can look something like so:

function Fruit(emoji) {_x000D_
  this.emoji = emoji;_x000D_
}_x000D_
_x000D_
Fruit.prototype.show = function () {_x000D_
  console.log(this.emoji);_x000D_
};_x000D_
_x000D_
const apple = new Fruit('');_x000D_
const orange = new Fruit('');_x000D_
_x000D_
apple.show();  // _x000D_
orange.show(); // _x000D_
_x000D_
const fruit1 = apple.show;_x000D_
const fruit2 = apple.show.bind();_x000D_
const fruit3 = apple.show.bind(apple);_x000D_
const fruit4 = apple.show.bind(orange);_x000D_
_x000D_
fruit1(); // undefined_x000D_
fruit2(); // undefined_x000D_
fruit3(); // _x000D_
fruit4(); // 

n = int(input())          #n is the number of items you want to enter
d ={}                     
for i in range(n):        
    text = input().split()     #split the input text based on space & store in the list 'text'
    d[text[0]] = text[1]       #assign the 1st item to key and 2nd item to value of the dictionary
print(d)

INPUT:

3

A1023 CRT

A1029 Regulator

A1030 Therm

NOTE: I have added an extra line for each input for getting each input on individual lines on this site. As placing without an extra line creates a single line.

OUTPUT:

{'A1023': 'CRT', 'A1029': 'Regulator', 'A1030': 'Therm'}

To get this in a ListFragment:

getListView().setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL); 
getListView().setStackFromBottom(true);`

Added this answer because if someone do a google search for same problem with ListFragment he just finds this..

Just change PrintWriter out = new PrintWriter(log); to

PrintWriter out = new PrintWriter(new FileWriter(log, true));

U can use something like this....

  function (field,value) {

         var newItemOrder= value;
          // Make sure user hasnt already added this item
        angular.forEach(arr, function(item) {
            if (newItemOrder == item.value) {
                arr.splice(arr.pop(item));

            } });

        submitFields.push({"field":field,"value":value});
    };

If you haven't commit the local changes yet since the last pull/clone, you can use:

git checkout *
git pull

checkout will clear your local changes with the last local commit, and pull will sincronize it to the remote repository

One does not imply the other. For a language to be statically typed it means that the types of all variables are known or inferred at compile time.

A strongly typed language does not allow you to use one type as another. C is a weakly typed language and is a good example of what strongly typed languages don't allow. In C you can pass a data element of the wrong type and it will not complain. In strongly typed languages you cannot.

TempData is also a dictionary object that stays for the time of an HTTP Request. So, TempData can be used to maintain data between one controller action to the other controller action.

TempData is used to check the null values each time. TempData contain two method keep() and peek() for maintain data state from one controller action to others.

When TempDataDictionary object is read, At the end of request marks as deletion to current read object.

The keep() and peek() method is used to read the data without deletion the current read object.

You can use Peek() when you always want to hold/prevent the value for another request. You can use Keep() when prevent/hold the value depends on additional logic.

Overloading in TempData.Peek() & TempData.Keep() as given below.

TempData.Keep() have 2 overloaded methods.

1. void keep() : That menace all the data not deleted on current request completion.

2. void keep(string key) : persist the specific item in TempData with help of name.

TempData.Peek() no overloaded methods.

1. object peek(string key) : return an object that contain items with specific key without making key for deletion.

Example for return type of TempData.Keep() & TempData.Peek() methods as given below.

public void Keep(string key) { _retainedKeys.Add(key); }

public object Peek(string key) { object value = values; return value; }

For the html code:

test.html

<button class="dismiss"  onclick="alert('hello')">
    <string for="exit">Dismiss</string>
</button>

the below python code worked for me. You can just try it.

from selenium import webdriver
import time

driver = webdriver.Chrome()
driver.get("http://localhost/gp/test.html")
button = driver.find_element_by_class_name("dismiss")
button.click()
time.sleep(5)
driver.quit()

You can assign an id to the specific link and add CSS. See the steps below:

1.Add an id of your choice (must be a unique name; can only start with text, not a number):

<a href="/abc/xyz" id="smallLinkButton">def</a>

2. Then add the necessary CSS as follows:

   #smallLinkButton:hover,active,visited{
   
         text-decoration: none;
         }
   

In My Aws Windows I Solved it and steps are

1. Open "C:\ProgramData\MySQL\MySQL Server 8.0"
2. Open My.ini
3. Find "[mysql]"
4. After "no-beep=" Brake Line and insert "default-character-set=utf8"
5. Find "[mysqld]"
6. Insert "collation-server = utf8_unicode_ci"
7. Insert "character-set-server = utf8"

example

...
# socket=MYSQL

port=3306

[mysql]
no-beep=
default-character-set=utf8
# default-character-set=

# SERVER SECTION
# ----------------------------------------------------------------------
# 
# The following options will be read by the MySQL Server. Make sure that
# you have installed the server correctly (see above) so it reads this 
# file.=
# 
# server_type=2
[mysqld]

collation-server = utf8_unicode_ci
character-set-server = utf8
# The next three options are mutually exclusive to SERVER_PORT below.
# skip-networking=
# enable-named-pipe=
# shared-memory=
...

A very simple approach:

def progbar(count: int) -> None:
    for i in range(count):
        print(f"[{i*'#'}{(count-1-i)*' '}] - {i+1}/{count}", end="\r")
        yield i
    print('\n')

And the usage:

from time import sleep

for i in progbar(10):
    sleep(0.2) #whatever task you need to do

I've found the same thing, but only on emulators that have the Use Host GPU setting ticked. Try turning that off, you'll no longer see those warnings (and the emulator will run horribly, horribly slowly..)

In my experience those warnings are harmless. Notice that the "error" is EGL_SUCCESS, which would seem to indicate no error at all!

If arr is an array, and val is the value you wish to add use:

arr.push(val);

E.g.

var arr = ['a', 'b', 'c'];_x000D_
arr.push('d');_x000D_
console.log(arr);

To actually do it in HTML with inline CSS (not with an external CSS style sheet)

<input type="text" style="font-size: 44pt">

A lot of people would consider putting the style right into the html like this to be poor form. However, I frequently make extreeemly simple web pages for my own use that don't even have a <html> or <body> tag, and such is appropriate there.

I have faced the same issue, once I upload build is not showing in AppStore Connect even I did not get any issue mail from apple. So I just wait for a day and that build begins visible on AppStore Connect after a day. It is a weird issue apple team have to look into it.

Happy coding. :)

In Swift 2.0, @user478681's answer might look like this:

    let HTMLDocumentPath = NSBundle.mainBundle().pathForResource("index", ofType: "html")
    let HTMLString: NSString?

    do {
        HTMLString = try NSString(contentsOfFile: HTMLDocumentPath!, encoding: NSUTF8StringEncoding)
    } catch {
        HTMLString = nil
    }

    myWebView.loadHTMLString(HTMLString as! String, baseURL: nil)

It has nothing to do with append. tuple(3, 4) all by itself raises that error.

The reason is that, as the error message says, tuple expects an iterable argument. You can make a tuple of the contents of a single object by passing that single object to tuple. You can't make a tuple of two things by passing them as separate arguments.

Just do (3, 4) to make a tuple, as in your first example. There's no reason not to use that simple syntax for writing a tuple.

first, you have to create a handler.

var specialElementHandlers = {
    '#editor': function(element, renderer){
        return true;
    }
};

then write this code in click event:

doc.fromHTML($('body').get(0), 15, 15, {
    'width': 170, 
    'elementHandlers': specialElementHandlers
        });

var pdfOutput = doc.output();
            console.log(">>>"+pdfOutput );

assuming you've already declared doc variable. And Then you have save this pdf file using File-Plugin.

You can use xpath as follows, try this one :

driver.findElement(By.xpath("(.//[@href='/docs/configuration'])")).click();

Triggering browser download from front-end is not reliable.

What you should do is, create an endpoint that when called, will provide the correct response headers, thus triggering the browser download.

Front-end code can only do so much. The 'download' attribute for example, might just open the file in a new tab depending on the browser.

The response headers you need to look at are probably Content-Type and Content-Disposition. You should check this answer for more detailed explanation.

Before initializing map check for is the map is already initiated or not

var container = L.DomUtil.get('map');

if(container != null){

container._leaflet_id = null;

}

It works for me

Change Minute parameter to 0.

You can set the cron for every three hours as:

I see most people confused about tf.shape(tensor) and tensor.get_shape() Let's make it clear:

1. tf.shape

tf.shape is used for dynamic shape. If your tensor's shape is changable, use it. An example: a input is an image with changable width and height, we want resize it to half of its size, then we can write something like:
new_height = tf.shape(image)[0] / 2

2. tensor.get_shape

tensor.get_shape is used for fixed shapes, which means the tensor's shape can be deduced in the graph.

Conclusion: tf.shape can be used almost anywhere, but t.get_shape only for shapes can be deduced from graph.

I had the same problem, so I wrote a Ruby gem called Twig. It lists branches in chronological order (newest first), and can also let you set a max age so that you don't list all branches (if you have a lot of them). For example:

$ twig

                              issue  status       todo            branch
                              -----  ------       ----            ------
2013-01-26 18:00:21 (7m ago)  486    In progress  Rebase          optimize-all-the-things
2013-01-26 16:49:21 (2h ago)  268    In progress  -               whitespace-all-the-things
2013-01-23 18:35:21 (3d ago)  159    Shipped      Test in prod  * refactor-all-the-things
2013-01-22 17:12:09 (4d ago)  -      -            -               development
2013-01-20 19:45:42 (6d ago)  -      -            -               master

It also lets you store custom properties for each branch, e.g., ticket id, status, todos, and filter the list of branches according to these properties. More info: http://rondevera.github.io/twig/

> myMatrix <- matrix(1:10, nrow=2)
> rownames(myMatrix) <- c("A", "B")
> colnames(myMatrix) <- c("A", "B", "C", "D", "E")

> myMatrix
  A B C D  E
A 1 3 5 7  9
B 2 4 6 8 10

> myMatrix["A", "A"]
[1] 1

> myMatrix["A", ]
A B C D E 
1 3 5 7 9 

> myMatrix[, "A"]
A B 
1 2 

Deleting full .m2 local repository solved my problem, too.

If you don't know where it is, the locations are:

Unix/Mac OS X – ~/.m2/repository
Windows – C:\Documents and Settings\{your-username}\.m2\repository 
        ( %USERPROFILE%\.m2\repository too, as suggested by **MC Empero** )

label {
    position: relative;
    display: inline-block;
}
select {
    display: inline-block;
    padding: 4px 3px 5px 5px;
    width: 150px;
    outline: none;
    color: black;
    border: 1px solid #C8BFC4;
    border-radius: 4px;
    box-shadow: inset 1px 1px 2px #ddd8dc;
    background-color: lightblue;
}

This uses a background color for select elements and I removed the image..

I had the same problem. Don't remember where I found it on the web, but here is what I did:

Click "Start button"

in the search box, enter "Turn windows features on or off"

in the features window, Click: "Internet Information Services"

Click: "World Wide Web Services"

Click: "Application Development Features"

Check (enable) the features. I checked all but CGI.

IIS - this configuration section cannot be used at this path (configuration locking?)

I use ConEmu (strongly recommended on Windows) where I have a task for starting Git Bash like

Note the button "Startup dir..." in the bottom. It adds a -new_console:d:<path> to the startup command of the Git Bash. Make it point to wherever you like

Th part of an URI after the # is called "fragment" and is by definition only available/processed on client side (see https://en.wikipedia.org/wiki/Fragment_identifier).

On the client side, this can be accessed using javaScript with window.location.hash.

To make it do nothing at all, use this:

<a href="javascript:void(0)"> ... </a>

CTRL + 1 can also be used which will suggest to import.

You can find the answer here: Is there a minlength validation attribute in HTML5?

Therefore this should do the job:

<input pattern=".{6,6}">

I found the example RichardTheKiwi quite informative.

Just to offer another approach if you're looking for something like IF EXISTS (SELECT 1 ..) THEN ...

-- what I might write in MSSQL

IF EXISTS (SELECT 1 FROM Table WHERE FieldValue='')
BEGIN
    SELECT TableID FROM Table WHERE FieldValue=''
END
ELSE
BEGIN
    INSERT INTO TABLE(FieldValue) VALUES('')
    SELECT SCOPE_IDENTITY() AS TableID
END

-- rewritten for MySQL

IF (SELECT 1 = 1 FROM Table WHERE FieldValue='') THEN
BEGIN
    SELECT TableID FROM Table WHERE FieldValue='';
END;
ELSE
BEGIN
    INSERT INTO Table (FieldValue) VALUES('');
    SELECT LAST_INSERT_ID() AS TableID;
END;
END IF;

Tossing my hat in the ring for fun, added advantage of memoizing

const callOnce = (fn, i=0, memo) => () => i++ ? memo : (memo = fn());

// usage
const myExpensiveFunction = () => { return console.log('joe'),5; }
const memoed = callOnce(myExpensiveFunction);
memoed(); //logs "joe", returns 5
memoed(); // returns 5
memoed(); // returns 5
...

try this

$.getJSON(url, function(data){
    $.each(data.response.venue.tips.groups.items, function (index, value) {
        console.log(this.text);
    });
});

If someone happens to be as moronic as me, the following worked.

Old folder structure:

awesome_code.py
__init__.py
    src/
        __init__.py
        stuff1.py
        stuff2.py

New structure:

awesome_code.py
    src/
        __init__.py
        stuff1.py
        stuff2.py

For those who don't have ImageMagick for whatever reason, GD functions will also work, in conjunction with GhostScript. Run the ghostscript command with exec() to convert a PDF to JPG, and manipulate the resulting file with imagecreatefromjpeg().

Run the ghostscript command:

exec('gs -dSAFER -dBATCH -sDEVICE=jpeg -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r300 -sOutputFile=whatever.jpg input.pdf')

To manipulate, create a new placeholder image, $newimage = imagecreatetruecolor(...), and bring in the current image. $image = imagecreatefromjpeg('whatever.jpg'), and then you can use imagecopyresampled() to change the size, or any number of other built-in, non-imagemagick commands

The example provided by @tster shows how to create a list of list. I will provide an example for iterating over such a list.

Iterator<List<String>> iter = listOlist.iterator();
while(iter.hasNext()){
    Iterator<String> siter = iter.next().iterator();
    while(siter.hasNext()){
         String s = siter.next();
         System.out.println(s);
     }
}

just insert the following line and use any color you like

    echo "<body style='background-color:pink'>";

#train_size is 1 - tst_size - vld_size
tst_size=0.15
vld_size=0.15

X_train_test, X_valid, y_train_test, y_valid = train_test_split(df.drop(y, axis=1), df.y, test_size = vld_size, random_state=13903) 

X_train_test_V=pd.DataFrame(X_train_test)
X_valid=pd.DataFrame(X_valid)

X_train, X_test, y_train, y_test = train_test_split(X_train_test, y_train_test, test_size=tst_size, random_state=13903)

In addition to installing the repository and the SDK packages one should be aware that the version number changes periodically. A simple solution at this point is to replace the specific version number with a plus (+) symbol.

compile 'com.google.android.gms:play-services:+'

Google instructions indicate that one should be sure to upgrade the version numbers, however adding the plus deals with the changes in versioning. Also note that when building in Android Studio a message will appear in the status line when a new version is available.

One can view the available versions of play services by drilling down on the correct repository path:

In this example, you may show your menu centered.

HTML

<div id="main-menu-container">
    <div id="main-menu">
        //your menu
    </div>
</div>

CSS

.f-nav{  /* To fix main menu container */
    z-index: 9999;
    position: fixed;
    left: 0;
    top: 0;
    width: 100%;
}
#main-menu-container {
    text-align: center; /* Assuming your main layout is centered */
}
#main-menu {
    display: inline-block;
    width: 1024px; /* Your menu's width */
}

JS

$("document").ready(function($){
    var nav = $('#main-menu-container');

    $(window).scroll(function () {
        if ($(this).scrollTop() > 125) {
            nav.addClass("f-nav");
        } else {
            nav.removeClass("f-nav");
        }
    });
});

I didn't understand the reasoning behind this but this solved the same problem I was facing. You may require these steps before executing steps mentioned in above solutions (Clean all projects and Build automatically).

right click project -> Properties -> Project Facets -> select Java -> Apply

Look in HTML output for actual client ID

You need to look in the generated HTML output to find out the right client ID. Open the page in browser, do a rightclick and View Source. Locate the HTML representation of the JSF component of interest and take its id as client ID. You can use it in an absolute or relative way depending on the current naming container. See following chapter.

Note: if it happens to contain iteration index like :0:, :1:, etc (because it's inside an iterating component), then you need to realize that updating a specific iteration round is not always supported. See bottom of answer for more detail on that.

Memorize NamingContainer components and always give them a fixed ID

If a component which you'd like to reference by ajax process/execute/update/render is inside the same NamingContainer parent, then just reference its own ID.

<h:form id="form">
    <p:commandLink update="result"> <!-- OK! -->
    <h:panelGroup id="result" />
</h:form>

If it's not inside the same NamingContainer, then you need to reference it using an absolute client ID. An absolute client ID starts with the NamingContainer separator character, which is by default :.

<h:form id="form">
    <p:commandLink update="result"> <!-- FAIL! -->
</h:form>
<h:panelGroup id="result" />

<h:form id="form">
    <p:commandLink update=":result"> <!-- OK! -->
</h:form>
<h:panelGroup id="result" />

<h:form id="form">
    <p:commandLink update=":result"> <!-- FAIL! -->
</h:form>
<h:form id="otherform">
    <h:panelGroup id="result" />
</h:form>

<h:form id="form">
    <p:commandLink update=":otherform:result"> <!-- OK! -->
</h:form>
<h:form id="otherform">
    <h:panelGroup id="result" />
</h:form>

NamingContainer components are for example <h:form>, <h:dataTable>, <p:tabView>, <cc:implementation> (thus, all composite components), etc. You recognize them easily by looking at the generated HTML output, their ID will be prepended to the generated client ID of all child components. Note that when they don't have a fixed ID, then JSF will use an autogenerated ID in j_idXXX format. You should absolutely avoid that by giving them a fixed ID. The OmniFaces NoAutoGeneratedIdViewHandler may be helpful in this during development.

If you know to find the javadoc of the UIComponent in question, then you can also just check in there whether it implements the NamingContainer interface or not. For example, the HtmlForm (the UIComponent behind <h:form> tag) shows it implements NamingContainer, but the HtmlPanelGroup (the UIComponent behind <h:panelGroup> tag) does not show it, so it does not implement NamingContainer. Here is the javadoc of all standard components and here is the javadoc of PrimeFaces.

Solving your problem

So in your case of:

<p:tabView id="tabs"><!-- This is a NamingContainer -->
    <p:tab id="search"><!-- This is NOT a NamingContainer -->
        <h:form id="insTable"><!-- This is a NamingContainer -->
            <p:dialog id="dlg"><!-- This is NOT a NamingContainer -->
                <h:panelGrid id="display">

The generated HTML output of <h:panelGrid id="display"> looks like this:

<table id="tabs:insTable:display">

You need to take exactly that id as client ID and then prefix with : for usage in update:

<p:commandLink update=":tabs:insTable:display">

Referencing outside include/tagfile/composite

If this command link is inside an include/tagfile, and the target is outside it, and thus you don't necessarily know the ID of the naming container parent of the current naming container, then you can dynamically reference it via UIComponent#getNamingContainer() like so:

<p:commandLink update=":#{component.namingContainer.parent.namingContainer.clientId}:display">

Or, if this command link is inside a composite component and the target is outside it:

<p:commandLink update=":#{cc.parent.namingContainer.clientId}:display">

Or, if both the command link and target are inside same composite component:

<p:commandLink update=":#{cc.clientId}:display">

How does it work under the covers

This all is specified as "search expression" in the UIComponent#findComponent() javadoc:

A search expression consists of either an identifier (which is matched exactly against the id property of a UIComponent, or a series of such identifiers linked by the UINamingContainer#getSeparatorChar character value. The search algorithm should operates as follows, though alternate alogrithms may be used as long as the end result is the same:

• Identify the UIComponent that will be the base for searching, by stopping as soon as one of the following conditions is met:
  • If the search expression begins with the the separator character (called an "absolute" search expression), the base will be the root UIComponent of the component tree. The leading separator character will be stripped off, and the remainder of the search expression will be treated as a "relative" search expression as described below.
  • Otherwise, if this UIComponent is a NamingContainer it will serve as the basis.
  • Otherwise, search up the parents of this component. If a NamingContainer is encountered, it will be the base.
  • Otherwise (if no NamingContainer is encountered) the root UIComponent will be the base.
• The search expression (possibly modified in the previous step) is now a "relative" search expression that will be used to locate the component (if any) that has an id that matches, within the scope of the base component. The match is performed as follows:
  • If the search expression is a simple identifier, this value is compared to the id property, and then recursively through the facets and children of the base UIComponent (except that if a descendant NamingContainer is found, its own facets and children are not searched).
  • If the search expression includes more than one identifier separated by the separator character, the first identifier is used to locate a NamingContainer by the rules in the previous bullet point. Then, the findComponent() method of this NamingContainer will be called, passing the remainder of the search expression.

Note that PrimeFaces also adheres the JSF spec, but RichFaces uses "some additional exceptions".

"reRender" uses UIComponent.findComponent() algorithm (with some additional exceptions) to find the component in the component tree.

Those additional exceptions are nowhere in detail described, but it's known that relative component IDs (i.e. those not starting with :) are not only searched in the context of the closest parent NamingContainer, but also in all other NamingContainer components in the same view (which is a relatively expensive job by the way).

Never use prependId="false"

If this all still doesn't work, then verify if you aren't using <h:form prependId="false">. This will fail during processing the ajax submit and render. See also this related question: UIForm with prependId="false" breaks <f:ajax render>.

Referencing specific iteration round of iterating components

It was for long time not possible to reference a specific iterated item in iterating components like <ui:repeat> and <h:dataTable> like so:

<h:form id="form">
    <ui:repeat id="list" value="#{['one','two','three']}" var="item">
        <h:outputText id="item" value="#{item}" /><br/>
    </ui:repeat>

    <h:commandButton value="Update second item">
        <f:ajax render=":form:list:1:item" />
    </h:commandButton>
</h:form>

However, since Mojarra 2.2.5 the <f:ajax> started to support it (it simply stopped validating it; thus you would never face the in the question mentioned exception anymore; another enhancement fix is planned for that later).

This only doesn't work yet in current MyFaces 2.2.7 and PrimeFaces 5.2 versions. The support might come in the future versions. In the meanwhile, your best bet is to update the iterating component itself, or a parent in case it doesn't render HTML, like <ui:repeat>.

When using PrimeFaces, consider Search Expressions or Selectors

PrimeFaces Search Expressions allows you to reference components via JSF component tree search expressions. JSF has several builtin:

• @this: current component
• @form: parent UIForm
• @all: entire document
• @none: nothing

PrimeFaces has enhanced this with new keywords and composite expression support:

• @parent: parent component
• @namingcontainer: parent UINamingContainer
• @widgetVar(name): component as identified by given widgetVar

You can also mix those keywords in composite expressions such as @form:@parent, @this:@parent:@parent, etc.

PrimeFaces Selectors (PFS) as in @(.someclass) allows you to reference components via jQuery CSS selector syntax. E.g. referencing components having all a common style class in the HTML output. This is particularly helpful in case you need to reference "a lot of" components. This only prerequires that the target components have all a client ID in the HTML output (fixed or autogenerated, doesn't matter). See also How do PrimeFaces Selectors as in update="@(.myClass)" work?

To select a value from the dropdown use the index like this:

if we have the

<asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="true"></asp:DropDownList>

you would use :

DropDownList1.Items[DropDownList1.SelectedIndex].Value

this would return the value for the selected index.

There is no way. You need a default constructor for array members and it will be called, afterwards, you can do any initialization you want in the constructor.

You can pass an object which is refering to all the values at a particular index.

import java.util.ArrayList;

public class HelloWorld{

 public static void main(String []args){


ArrayList<connect> a=new ArrayList<connect>();

a.add(new connect(100,100,100,100,100));

System.out.println(a.get(0).p1);

System.out.println(a.get(0).p2);

System.out.println(a.get(0).p3);
}

}

class connect
{
int p1,p2,p3,p4,p5;

connect(int a,int b,int c,int d,int e)
{

this.p1=a;

this.p2=b;

this.p3=c;

this.p4=d;

this.p5=e;
}

}

Later to get a particular value at a specific index, you can do this:

a.get(0).p1;

a.get(0).p2;

a.get(0).p3;.............

and so on.

First I added a to_dict method to my model ;

def to_dict(self):
    return {"name": self.woo, "title": self.foo}

Then I have this;

class DjangoJSONEncoder(JSONEncoder):

    def default(self, obj):
        if isinstance(obj, models.Model):
            return obj.to_dict()
        return JSONEncoder.default(self, obj)


dumps = curry(dumps, cls=DjangoJSONEncoder)

and at last use this class to serialize my queryset.

def render_to_response(self, context, **response_kwargs):
    return HttpResponse(dumps(self.get_queryset()))

This works quite well

In search of this same solution, I found what I needed under a different question in stackoverflow: Powershell-log-off-remote-session. The below one line will return a list of logged on users.

A static variable stays in the memory for the entire lifetime of the application, and is initialised during class loading. A non-static variable is being initialised each time you construct a new object. It's generally better to use:

private static final int NUMBER = 10;

Why? This reduces the memory footprint per instance. It possibly is also favourable for cache hits. And it just makes sense: static should be used for things that are shared across all instances (a.k.a. objects) of a certain type (a.k.a. class).

Execute following command:

set PATH="C:\Program Files (x86)\Java\jre7"

(whichever JRE exists in case of 64bit).

Because your Java Path is not set so you can just do this at command line and then execute the keytool import command.

@robertc has it right, but you also need to notice that svg, #container causes the svg to be scaled exponentially for anything but 100% (once for #container and once for svg).

In other words, if I applied 50% h/w to both elements, it's actually 50% of 50%, or .5 * .5, which equals .25, or 25% scale.

One selector works fine when used as @robertc suggests.

svg {
  width:50%;
  height:50%;
}

This error happened on my server when I imported a view with an invalid definer.

Removing the faulty view fixed the error.

The error message didn't say anything about the view in question, but was "complaining" about one of the tables, that was used in the view.

Here's what u can also try....

run your application....while it is still running launch your command prompt

while your application is running type netstat -n on the command prompt. You should see a list of TCP/IP connections. Check if your list is not very long. Ideally you should have less than 5 connections in the list. Check the status of the connections.
If you have too many connections with a TIME_WAIT status it means the connection has been closed and is waiting for the OS to release the resources. If you are running on Windows, the default ephemeral port rang is between 1024 and 5000 and the default time it takes Windows to release the resource from TIME_WAIT status is 4 minutes. So if your application used more then 3976 connections in less then 4 minutes, you will get the exception you got.

Suggestions to fix it:

1. Add a connection pool to your connection string.

If you continue to receive the same error message (which is highly unlikely) you can then try the following: (Please don't do it if you are not familiar with the Windows registry)

1. Run regedit from your run command. In the registry editor look for this registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters:

Modify the settings so they read:

MaxUserPort = dword:00004e20 (10,000 decimal) TcpTimedWaitDelay = dword:0000001e (30 decimal)

This will increase the number of ports to 10,000 and reduce the time to release freed tcp/ip connections.

Only use suggestion 2 if 1 fails.

Thank you.

A pixel is the smallest unit value to render something with, but you can trick thickness with optical illusions by modifying colors (the eye can only see up to a certain resolution too).

Here is a test to prove this point:

div { border-color: blue; border-style: solid; margin: 2px; }

div.b1 { border-width: 1px; }
div.b2 { border-width: 0.1em; }
div.b3 { border-width: 0.01em; }
div.b4 { border-width: 1px; border-color: rgb(160,160,255); }

<div class="b1">Some text</div>
<div class="b2">Some text</div>
<div class="b3">Some text</div>
<div class="b4">Some text</div>

Output

Which gives the illusion that the last DIV has a smaller border width, because the blue border blends more with the white background.

Edit: Alternate solution

Alpha values may also be used to simulate the same effect, without the need to calculate and manipulate RGB values.

.container {
  border-style: solid;
  border-width: 1px;
  
  margin-bottom: 10px;
}

.border-100 { border-color: rgba(0,0,255,1); }
.border-75 { border-color: rgba(0,0,255,0.75); }
.border-50 { border-color: rgba(0,0,255,0.5); }
.border-25 { border-color: rgba(0,0,255,0.25); }

<div class="container border-100">Container 1 (alpha = 1)</div>
<div class="container border-75">Container 2 (alpha = 0.75)</div>
<div class="container border-50">Container 3 (alpha = 0.5)</div>
<div class="container border-25">Container 4 (alpha = 0.25)</div>

There is a weird case where if the element is set to display: inline the jQuery check for visibility fails.

Example:

CSS

#myspan {display: inline;}

jQuery

$('#myspan').show(); // Our element is `inline` instead of `block`
$('#myspan').is(":visible"); // This is false

To fix it you can hide the element in jQuery and than show/hide or toggle() should work fine.

$('#myspan').hide()
$('#otherElement').on('click', function() {
    $('#myspan').toggle();
});

Use "this.FinishAndRemoveTask();" - it closes application properly

Dim fileEntries As String() = Directory.GetFiles("YourPath", "*.txt")
' Process the list of .txt files found in the directory. '
Dim fileName As String

For Each fileName In fileEntries
    If (System.IO.File.Exists(fileName)) Then
        'Read File and Print Result if its true
        ReadFile(fileName)
    End If
    TransfereFile(fileName, 1)
Next

You can use a HybridDictionary which automaticly detects the breaking point, and accepts null-values, making it essentialy the same as a HashSet.

If you create a tag by e.g.

git tag v1.0

the tag will refer to the most recent commit of the branch you are currently on. You can change branch and create a tag there.

You can also just refer to the other branch while tagging,

git tag v1.0 name_of_other_branch

which will create the tag to the most recent commit of the other branch.

Or you can just put the tag anywhere, no matter which branch, by directly referencing to the SHA1 of some commit

git tag v1.0 <sha1>

Here's a "one-liner", spread over multiple lines, in functional programming style:

def variance(data, opt=0):
    return (lambda (m2, i, _): m2 / (opt + i - 1))(
        reduce(
            lambda (m2, i, avg), x:
            (
                m2 + (x - avg) ** 2 * i / (i + 1),
                i + 1,
                avg + (x - avg) / (i + 1)
            ),
            data,
            (0, 0, 0)))

How are you doing the compiling and linking? You'll need to specify both files, something like:

gcc testpoint.c point.c

...so that it knows to link the functions from both together. With the code as it's written right now, however, you'll then run into the opposite problem: multiple definitions of main. You'll need/want to eliminate one (undoubtedly the one in point.c).

In a larger program, you typically compile and link separately to avoid re-compiling anything that hasn't changed. You normally specify what needs to be done via a makefile, and use make to do the work. In this case you'd have something like this:

OBJS=testpoint.o point.o

testpoint.exe: $(OBJS)
    gcc $(OJBS)

The first is just a macro for the names of the object files. You get it expanded with $(OBJS). The second is a rule to tell make 1) that the executable depends on the object files, and 2) telling it how to create the executable when/if it's out of date compared to an object file.

Most versions of make (including the one in MinGW I'm pretty sure) have a built-in "implicit rule" to tell them how to create an object file from a C source file. It normally looks roughly like this:

.c.o:
    $(CC) -c $(CFLAGS) $<

This assumes the name of the C compiler is in a macro named CC (implicitly defined like CC=gcc) and allows you to specify any flags you care about in a macro named CFLAGS (e.g., CFLAGS=-O3 to turn on optimization) and $< is a special macro that expands to the name of the source file.

You typically store this in a file named Makefile, and to build your program, you just type make at the command line. It implicitly looks for a file named Makefile, and runs whatever rules it contains.

The good point of this is that make automatically looks at the timestamps on the files, so it will only re-compile the files that have changed since the last time you compiled them (i.e., files where the ".c" file has a more recent time-stamp than the matching ".o" file).

Also note that 1) there are lots of variations in how to use make when it comes to large projects, and 2) there are also lots of alternatives to make. I've only hit on the bare minimum of high points here.

You only need to force cscript instead wscript. I always use this template. The function ForceConsole() will execute your vbs into cscript, also you have nice alias to print and scan text.

 Set oWSH = CreateObject("WScript.Shell")
 vbsInterpreter = "cscript.exe"

 Call ForceConsole()

 Function printf(txt)
    WScript.StdOut.WriteLine txt
 End Function

 Function printl(txt)
    WScript.StdOut.Write txt
 End Function

 Function scanf()
    scanf = LCase(WScript.StdIn.ReadLine)
 End Function

 Function wait(n)
    WScript.Sleep Int(n * 1000)
 End Function

 Function ForceConsole()
    If InStr(LCase(WScript.FullName), vbsInterpreter) = 0 Then
        oWSH.Run vbsInterpreter & " //NoLogo " & Chr(34) & WScript.ScriptFullName & Chr(34)
        WScript.Quit
    End If
 End Function

 Function cls()
    For i = 1 To 50
        printf ""
    Next
 End Function

 printf " _____ _ _           _____         _    _____         _     _   "
 printf "|  _  |_| |_ ___ ___|     |_ _ _ _| |  |   __|___ ___|_|___| |_ "
 printf "|     | | '_| . |   |   --| | | | . |  |__   |  _|  _| | . |  _|"
 printf "|__|__|_|_,_|___|_|_|_____|_____|___|  |_____|___|_| |_|  _|_|  "
 printf "                                                       |_|     v1.0"
 printl " Enter your name:"
 MyVar = scanf
 cls
 printf "Your name is: " & MyVar
 wait(5)

Technical differences are a consequence of the goal of each one (OpenJDK is meant to be the reference implementation, open to the community, while Oracle is meant to be a commercial one)

They both have "almost" the same code of the classes in the Java API; but the code for the virtual machine itself is actually different, and when it comes to libraries, OpenJDK tends to use open libraries while Oracle tends to use closed ones; for instance, the font library.

There are a lot of good answers here, but I thought some people might find mine useful. I like it because the interface that you use to define the macro is about as simple as it can get. It's also handy because you don't have to include any extra libraries - it all comes with C++ and it doesn't even require a really late version. I pulled pieces from various places online so I can't take credit for all of it, but I think it's unique enough to warrant a new answer.

First make a header file... call it EnumMacros.h or something like that, and put this in it:

// Search and remove whitespace from both ends of the string
static std::string TrimEnumString(const std::string &s)
{
    std::string::const_iterator it = s.begin();
    while (it != s.end() && isspace(*it)) { it++; }
    std::string::const_reverse_iterator rit = s.rbegin();
    while (rit.base() != it && isspace(*rit)) { rit++; }
    return std::string(it, rit.base());
}

static void SplitEnumArgs(const char* szArgs, std::string Array[], int nMax)
{
    std::stringstream ss(szArgs);
    std::string strSub;
    int nIdx = 0;
    while (ss.good() && (nIdx < nMax)) {
        getline(ss, strSub, ',');
        Array[nIdx] = TrimEnumString(strSub);
        nIdx++;
    }
};
// This will to define an enum that is wrapped in a namespace of the same name along with ToString(), FromString(), and COUNT
#define DECLARE_ENUM(ename, ...) \
    namespace ename { \
        enum ename { __VA_ARGS__, COUNT }; \
        static std::string _Strings[COUNT]; \
        static const char* ToString(ename e) { \
            if (_Strings[0].empty()) { SplitEnumArgs(#__VA_ARGS__, _Strings, COUNT); } \
            return _Strings[e].c_str(); \
        } \
        static ename FromString(const std::string& strEnum) { \
            if (_Strings[0].empty()) { SplitEnumArgs(#__VA_ARGS__, _Strings, COUNT); } \
            for (int i = 0; i < COUNT; i++) { if (_Strings[i] == strEnum) { return (ename)i; } } \
            return COUNT; \
        } \
    }

Then, in your main program you can do this...

#include "EnumMacros.h"
DECLARE_ENUM(OsType, Windows, Linux, Apple)

void main() {
    OsType::OsType MyOs = OSType::Apple;
    printf("The value of '%s' is: %d of %d\n", OsType::ToString(MyOs), (int)OsType::FromString("Apple"), OsType::COUNT);
}

Where the output would be >> The value of 'Apple' is: 2 of 4

To expand on my comment.

You can validate on the command line using php -l [filename], which does a syntax check only (lint). This will depend on your php.ini error settings, so you can edit you php.ini or set the error_reporting in the script.

Here's an example of the output when run on a file containing:

<?php
echo no quotes or semicolon

Results in:

PHP Parse error:  syntax error, unexpected T_STRING, expecting ',' or ';' in badfile.php on line 2

Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in badfile.php on line 2

Errors parsing badfile.php

I suggested you build your own validator.

A simple page that allows you to upload a php file. It takes the uploaded file runs it through php -l and echos the output.

Note: this is not a security risk it does not execute the file, just checks for syntax errors.

Here's a really basic example of creating your own:

<?php
if (isset($_FILES['file'])) {
    echo '<pre>';
    passthru('php -l '.$_FILES['file']['tmp_name']);
    echo '</pre>';
}
?>
<form action="" method="post" enctype="multipart/form-data">
    <input type="file" name="file"/>
    <input type="submit"/>
</form>

<a href="#" onClick="window.open('http://www.yahoo.com', '_blank')">test</a>

Easy as that.

Or without JS

<a href="http://yahoo.com" target="_blank">test</a>

As a quick and very scoped solution:

Task.Result

Both Task.Result and Task.Wait won't allow to improving scalability when used with I/O, as they will cause the calling thread to stay blocked waiting for the I/O to end.

When you call .Result on an incomplete Task, the thread executing the method has to sit and wait for the task to complete, which blocks the thread from doing any other useful work in the meantime. This negates the benefit of the asynchronous nature of the task.

notasync

Another simple way:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).Select    
Selection.EntireRow.Delete

or simpler:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).EntireRow.Delete

SELECT * 
  FROM TABLENAME 
 WHERE [DateTime] >= '2011-04-12 12:00:00 AM'
   AND [DateTime] <= '2011-05-25 3:35:04 AM'

If this doesn't work, please script out your table and post it here. this will help us get you the correct answer quickly.

Check out the final-fs library. It provides a readdirRecursive function:

ffs.readdirRecursive(dirPath, true, 'my/initial/path')
    .then(function (files) {
        // in the `files` variable you've got all the files
    })
    .otherwise(function (err) {
        // something went wrong
    });

runAllManagedModulesForAllRequests=true is actually a real bad solution. This increased the load time of my application by 200%. The better solution is to manually remove and add the session object and to avoid the run all managed modules attribute all together.

As "M.A. Hanin" said above, it can caused by an InnerException like this:

and I deleted the folder: C:\Users\Pourakbar.h\AppData\Local\Accounting\Accounting.vshost.exe_Url_a4h1gnabohiu4wgiejk0d21rc2kbwr4g from my computer and that worked for me!

Here is your answer. use

                   jquery.json-2.2.min.js 
                      and
                   jquery-1.8.3.min.js

Javascript :

function CallAddToCart(eitemId, equantity) {
   var itemId = Number(eitemId);
   var quantity = equantity;
   var dataValue = "{itemId:'" + itemId+ "', quantity :'"+ quantity "'}" ;
    $.ajax({
           url: "AddToCart.aspx/AddTo_Cart",
           type: "POST",
           dataType: "json",
           data: dataValue,
           contentType: "application/json; charset=utf-8",
           success: function (msg) {
                alert("Success");
           },
           error: function () { alert(arguments[2]); }      
        });
 }

and your C# web method should be

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static string AddTo_Cart(int itemId, string quantity)
{
   SpiritsShared.ShoppingCart.AddItem(itemId, quantity);      
  return "Item Added Successfully";
}

From any of the button click or any other html control event you can call to the javascript method with the parameter which in turn calls to the webmethod to get the value in json format.

You can simply write:

char c = (char) 2;

or

char c = Convert.ToChar(2);

or more complex option for ASCII encoding only

char[] characters = System.Text.Encoding.ASCII.GetChars(new byte[]{2});
char c = characters[0];

The easiest way is this.

byte[] bytes = rs.getBytes("my_field");

INSERT TEMP SELECT DATA INTO TEMP TABLE

-- INSERT COMMON DATA
Insert Into #MyTempTable
Select EmployeeID from [EmployeeMaster] Where EmployeeID between 1 and 100

SELECT TEMP TABLE (You can now use this select query)

Select EmployeeID from #MyTempTable

FINAL STEP DROP THE TABLE

Drop Table #MyTempTable

I hope this will help. Simple and Clear :)

Adjusting the currentScale attribute works in IE ( I tested with IE 11), but not in Chrome.

If you are using python 3.6 and newer then you can use f-strings to do the task like this.

print(f"I have {card.price}")

just include f in front of your string and add the variable inside curly braces { }.

Refer to a blog The new f-strings in Python 3.6: written by Christoph Zwerschke which includes execution times of the various method.

I believe the normal answer is that it should be passed by value if you need to make a copy of it in your function. Pass it by const reference otherwise.

Here is a good discussion: http://cpp-next.com/archive/2009/08/want-speed-pass-by-value/

Give headercss position fixed.

.headercss {
    width: 100%;
    height: 320px;
    background-color: #000000;
    position: fixed;
    top:0
}

Then give the content container a 320px padding-top, so it doesn't get behind the header.

you can also try the more generic version which gives you the ith element

enumerable.ElementAtOrDefault(i));

hope it helps

With the same error message as Will, it worked for me to install mysql first as the missing file will be added during the installation. So after

brew install mysql

pip install mysql-python

ran without errors.

Edit 7/17/2020: I cannot delete this accepted answer. It used to be good, but now it isn't. Beware really old posts, guys. I'm removing the link.

[Linqer] is a SQL to LINQ converter tool. It helps you to learn LINQ and convert your existing SQL statements.

Not every SQL statement can be converted to LINQ, but Linqer covers many different types of SQL expressions. Linqer supports both .NET languages - C# and Visual Basic.

:match CursorLine /\s\+/

avoids the "you have to search for spaces to get them to show up" bit but afaict can't be configured to do non-hilighting things to the spaces. CursorLine can be any hilighting group and in the default theme it's a plain underline.

As per the latest bootstrap v3.3.7 xs-offseting is allowed. See the documentation here bootstrap offseting. So you can use

<div class="col-xs-2 col-xs-offset-1">.col-xs-2 .col-xs-offset-1</div>

What I would suggest is not converting the non-static class to a static class because in that case, your inner class can't access the non-static members of outer class.

Example :

class Outer
{
    class Inner
    {
        //...
    }
}

So, in such case, you can do something like:

Outer o = new Outer();
Outer.Inner obj = o.new Inner();

Ok... this took me way too long. The sql-management studio tool is just not up to simple things like this (which I've noticed before when looking for where to set the timeout on queries, and it was done in 4 different locations)

I downloaded some other sql editor package (sql maestro in my case). And behold it includes a blob editor where you can look at blobs, and load new blobs into these field.

thanks for the input!

This works fine:

var sql = @"select top 1 person_id PersonId, first_name FirstName, last_name LastName from Person";
using (var conn = ConnectionFactory.GetConnection())
{
    var person = conn.Query<Person>(sql).ToList();
    return person;
}

Dapper has no facility that allows you to specify a Column Attribute, I am not against adding support for it, providing we do not pull in the dependency.

I think I have the solution to your question, assuming you can use flexbox in your project. What you want to do is make #one a flexbox using display: flex and use flex-direction: column to make it a column alignment.

My 2cents, in a single system user you can set the port also on /etc/ssh/ssh_config then rsync will use the port set here

import queue is lowercase q in Python 3.

Change Q to q and it will be fine.

(See code in https://stackoverflow.com/a/29688081/632951 for smart switching.)

This is how it worked for me.

Object

var my_object ={"Super Hero":["Iron Man", "Super Man"]};

Set

Encode the stringified object with encodeURIComponent() and set as attribute:

var data_str = encodeURIComponent(JSON.stringify(my_object));
$("div#mydiv").attr("data-hero",data-str);

Get

To get the value as an object, parse the decoded, with decodeURIComponent(), attribute value:

var data_str = $("div#mydiv").attr("data-hero");
var my_object = JSON.parse(decodeURIComponent(data_str));

NOTE: This is mentioned in the question but restarting Visual Studio fixes the issue in most cases.

Updating Visual Studio to 'Update 2' got it working again.

Tools -> Extensions and Updates ->Visual Studio Update 2

As mentioned in the question and the link i posted therein, I'd already updated NuGet Package Manager to 3.4.4 prior to this and restarted to no avail, so I don't know if the combination of both these actions worked.

Why don't you go for the easiest approach. For most cases you want to add icons like font awesome... Just use font awesome library and it would be as easy to add an icon to an text field as this:

myTextField.setLeftViewFAIcon(icon: .FAPlus, leftViewMode: .always, textColor: .red, backgroundColor: .clear, size: nil)

You would need to install first this swift library: https://github.com/Vaberer/Font-Awesome-Swift

I solved my problem with code below.

display: table-caption;

You should take a look to Quartz it's a java framework wich works with EE and SE editions and allows to define jobs to execute an specific time

This way:

db.collection_name.find().toArray().then(...function...)

I think it is a better idea to start working with a raw data and then translate it to DOM (document object model)

I would suggest you to work with array of objects and then output it to the DOM in order to accomplish your task.

You can see working example of following code at http://www.softxml.com/stackoverflow/shoppingCart.htm

You can try following approach:

//create array that will hold all ordered products
    var shoppingCart = [];

    //this function manipulates DOM and displays content of our shopping cart
    function displayShoppingCart(){
        var orderedProductsTblBody=document.getElementById("orderedProductsTblBody");
        //ensure we delete all previously added rows from ordered products table
        while(orderedProductsTblBody.rows.length>0) {
            orderedProductsTblBody.deleteRow(0);
        }

        //variable to hold total price of shopping cart
        var cart_total_price=0;
        //iterate over array of objects
        for(var product in shoppingCart){
            //add new row      
            var row=orderedProductsTblBody.insertRow();
            //create three cells for product properties 
            var cellName = row.insertCell(0);
            var cellDescription = row.insertCell(1);
            var cellPrice = row.insertCell(2);
            cellPrice.align="right";
            //fill cells with values from current product object of our array
            cellName.innerHTML = shoppingCart[product].Name;
            cellDescription.innerHTML = shoppingCart[product].Description;
            cellPrice.innerHTML = shoppingCart[product].Price;
            cart_total_price+=shoppingCart[product].Price;
        }
        //fill total cost of our shopping cart 
        document.getElementById("cart_total").innerHTML=cart_total_price;
    }


    function AddtoCart(name,description,price){
       //Below we create JavaScript Object that will hold three properties you have mentioned:    Name,Description and Price
       var singleProduct = {};
       //Fill the product object with data
       singleProduct.Name=name;
       singleProduct.Description=description;
       singleProduct.Price=price;
       //Add newly created product to our shopping cart 
       shoppingCart.push(singleProduct);
       //call display function to show on screen
       displayShoppingCart();

    }  


    //Add some products to our shopping cart via code or you can create a button with onclick event
    //AddtoCart("Table","Big red table",50);
    //AddtoCart("Door","Big yellow door",150);
    //AddtoCart("Car","Ferrari S23",150000);

It works on my project. Thanks.

If you have a modern Windows (that has powershell installed), the following may work fine as well

call :PrintBright Something Something

  (do actual batch stuff here)

call :PrintBright Done!
goto :eof


:PrintBright
powershell -Command Write-Host "%*" -foreground "White"

Adjust the color as you see fit.

Did some tests both on linux and windows. I use a test file containing lines ending in LF and also lines ending in CRLF.
File is committed , removed and then checked out. The value of core.autocrlf is set before commit and also before checkout. The result is below.

commit core.autocrlf false, remove, checkout core.autocrlf false: LF=>LF   CRLF=>CRLF  
commit core.autocrlf false, remove, checkout core.autocrlf input: LF=>LF   CRLF=>CRLF  
commit core.autocrlf false, remove, checkout core.autocrlf true : LF=>LF   CRLF=>CRLF  
commit core.autocrlf input, remove, checkout core.autocrlf false: LF=>LF   CRLF=>LF  
commit core.autocrlf input, remove, checkout core.autocrlf input: LF=>LF   CRLF=>LF  
commit core.autocrlf input, remove, checkout core.autocrlf true : LF=>CRLF CRLF=>CRLF  
commit core.autocrlf true, remove, checkout core.autocrlf false: LF=>LF   CRLF=>LF  
commit core.autocrlf true, remove, checkout core.autocrlf input: LF=>LF   CRLF=>LF  
commit core.autocrlf true,  remove, checkout core.autocrlf true : LF=>CRLF CRLF=>CRLF  

There's an app for that. Well, module. Well, more than one, probably hundreds.

Yargs is one of the fun ones, its docs are cool to read.

Here's an example from the github/npm page:

#!/usr/bin/env node
var argv = require('yargs').argv;
console.log('(%d,%d)', argv.x, argv.y);
console.log(argv._);

Output is here (it reads options with dashes etc, short and long, numeric etc).

$ ./nonopt.js -x 6.82 -y 3.35 rum
(6.82,3.35)
[ 'rum' ] 
$ ./nonopt.js "me hearties" -x 0.54 yo -y 1.12 ho
(0.54,1.12)
[ 'me hearties', 'yo', 'ho' ]

ALTER TABLE provider ADD PRIMARY KEY(person,place,thing);

If a primary key already exists then you want to do this

ALTER TABLE provider DROP PRIMARY KEY, ADD PRIMARY KEY(person, place, thing);

The problem can also be an alias used for a default export.

Change

import { Button as ButtonTest } from "../theme/components/Button";

to

import { default as ButtonTest } from "../theme/components/Button";

solved the issue for me.

For brevity, here's an ES2015 sample that doesn't rely on global variables

// controllers/example-controller.js

export const ExampleControllerName = "ExampleController"
export const ExampleController = ($scope) => {
  // something... 
}

// controllers/another-controller.js

export const AnotherControllerName = "AnotherController"
export const AnotherController = ($scope) => {
  // functionality... 
}

// app.js

import angular from "angular";

import {
  ExampleControllerName,
  ExampleController
} = "./controllers/example-controller";

import {
  AnotherControllerName,
  AnotherController
} = "./controllers/another-controller";

angular.module("myApp", [/* deps */])
  .controller(ExampleControllerName, ExampleController)
  .controller(AnotherControllerName, AnotherController)

You must write correct full path. Don't use '~/Library/Android/sdk'

vi ~/.bashrc

export ANDROID_HOME=/Users/{UserName}/Library/Android/sdk
export PATH=${PATH}:${ANDROID_HOME}/tools
export PATH=${PATH}:${ANDROID_HOME}/platform-tools

source ~/.bashrc

Try moving that mysql.bak directory out of /var/lib/mysql to say /root/ or something. It seems like mysql is finding that and it may be causing that ERROR 1102 (42000): Incorrect database name 'mysql.bak' error.

I am not sure what you are trying to accomplish. But here are some thoughts:
1. Convert to integer:
num = as.integer(123.2342)
2. Check if a variable is an integer:
is.integer(num)
typeof(num)=="integer"

As @yigit mentioned, you need to override onMeasure(). Both @user2302510 and @DenisNek have good answers but if you want to support ItemDecoration you can use this custom layout manager.

And other answers cannot scroll when there are more items than can be displayed on the screen though. This one is using default implemantation of onMeasure() when there are more items than screen size.

public class MyLinearLayoutManager extends LinearLayoutManager {

public MyLinearLayoutManager(Context context, int orientation, boolean reverseLayout)    {
    super(context, orientation, reverseLayout);
}

private int[] mMeasuredDimension = new int[2];

@Override
public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state,
                      int widthSpec, int heightSpec) {
    final int widthMode = View.MeasureSpec.getMode(widthSpec);
    final int heightMode = View.MeasureSpec.getMode(heightSpec);
    final int widthSize = View.MeasureSpec.getSize(widthSpec);
    final int heightSize = View.MeasureSpec.getSize(heightSpec);
    int width = 0;
    int height = 0;
    for (int i = 0; i < getItemCount(); i++) {
        measureScrapChild(recycler, i,
                View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                mMeasuredDimension);

        if (getOrientation() == HORIZONTAL) {
            width = width + mMeasuredDimension[0];
            if (i == 0) {
                height = mMeasuredDimension[1];
            }
        } else {
            height = height + mMeasuredDimension[1];
            if (i == 0) {
                width = mMeasuredDimension[0];
            }
        }
    }

    // If child view is more than screen size, there is no need to make it wrap content. We can use original onMeasure() so we can scroll view.
    if (height < heightSize && width < widthSize) {

        switch (widthMode) {
            case View.MeasureSpec.EXACTLY:
                width = widthSize;
            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        switch (heightMode) {
            case View.MeasureSpec.EXACTLY:
                height = heightSize;
            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        setMeasuredDimension(width, height);
    } else {
        super.onMeasure(recycler, state, widthSpec, heightSpec);
    }
}

private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                               int heightSpec, int[] measuredDimension) {

   View view = recycler.getViewForPosition(position);

   // For adding Item Decor Insets to view
   super.measureChildWithMargins(view, 0, 0);
    if (view != null) {
        RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();
        int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
                    getPaddingLeft() + getPaddingRight() + getDecoratedLeft(view) + getDecoratedRight(view), p.width);
            int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
                    getPaddingTop() + getPaddingBottom() + getPaddingBottom() + getDecoratedBottom(view) , p.height);
            view.measure(childWidthSpec, childHeightSpec);

            // Get decorated measurements
            measuredDimension[0] = getDecoratedMeasuredWidth(view) + p.leftMargin + p.rightMargin;
            measuredDimension[1] = getDecoratedMeasuredHeight(view) + p.bottomMargin + p.topMargin;
            recycler.recycleView(view);
        }
    }
}

And if you want to use it with GridLayoutManager just extends it from GridLayoutManager and change

for (int i = 0; i < getItemCount(); i++)

to

for (int i = 0; i < getItemCount(); i = i + getSpanCount())

For languages not specifying a memory model, you are writing code for the language and the memory model specified by the processor architecture. The processor may choose to re-order memory accesses for performance. So, if your program has data races (a data race is when it's possible for multiple cores / hyper-threads to access the same memory concurrently) then your program is not cross platform because of its dependence on the processor memory model. You may refer to the Intel or AMD software manuals to find out how the processors may re-order memory accesses.

Very importantly, locks (and concurrency semantics with locking) are typically implemented in a cross platform way... So if you are using standard locks in a multithreaded program with no data races then you don't have to worry about cross platform memory models.

Interestingly, Microsoft compilers for C++ have acquire / release semantics for volatile which is a C++ extension to deal with the lack of a memory model in C++ http://msdn.microsoft.com/en-us/library/12a04hfd(v=vs.80).aspx. However, given that Windows runs on x86 / x64 only, that's not saying much (Intel and AMD memory models make it easy and efficient to implement acquire / release semantics in a language).

I just bumped into the same problem and I used the following solution (all from Package Manager Console)

PM> Enable-Migrations -MigrationsDirectory "Migrations\ContextA" -ContextTypeName MyProject.Models.ContextA
PM> Enable-Migrations -MigrationsDirectory "Migrations\ContextB" -ContextTypeName MyProject.Models.ContextB

This will create 2 separate folders in the Migrations folder. Each will contain the generated Configuration.cs file. Unfortunately you still have to rename those Configuration.cs files otherwise there will be complaints about having two of them. I renamed my files to ConfigA.cs and ConfigB.cs

EDIT: (courtesy Kevin McPheat) Remember when renaming the Configuration.cs files, also rename the class names and constructors /EDIT

With this structure you can simply do

PM> Add-Migration -ConfigurationTypeName ConfigA
PM> Add-Migration -ConfigurationTypeName ConfigB

Which will create the code files for the migration inside the folder next to the config files (this is nice to keep those files together)

PM> Update-Database -ConfigurationTypeName ConfigA
PM> Update-Database -ConfigurationTypeName ConfigB

And last but not least those two commands will apply the correct migrations to their corrseponding databases.

EDIT 08 Feb, 2016: I have done a little testing with EF7 version 7.0.0-rc1-16348

I could not get the -o|--outputDir option to work. It kept on giving Microsoft.Dnx.Runtime.Common.Commandline.CommandParsingException: Unrecognized command or argument

However it looks like the first time an migration is added it is added into the Migrations folder, and a subsequent migration for another context is automatically put into a subdolder of migrations.

The original names ContextA seems to violate some naming conventions so I now use ContextAContext and ContextBContext. Using these names you could use the following commands: (note that my dnx still works from the package manager console and I do not like to open a separate CMD window to do migrations)

PM> dnx ef migrations add Initial -c "ContextAContext"
PM> dnx ef migrations add Initial -c "ContextBContext"

This will create a model snapshot and a initial migration in the Migrations folder for ContextAContext. It will create a folder named ContextB containing these files for ContextBContext

I manually added a ContextA folder and moved the migration files from ContextAContext into that folder. Then I renamed the namespace inside those files (snapshot file, initial migration and note that there is a third file under the initial migration file ... designer.cs). I had to add .ContextA to the namespace, and from there the framework handles it automatically again.

Using the following commands would create a new migration for each context

PM>  dnx ef migrations add Update1 -c "ContextAContext"
PM>  dnx ef migrations add Update1 -c "ContextBContext"

and the generated files are put in the correct folders.

I also got the same error when using ajax with a textbox then i solve it by remove class select2 of textbox and setup select2 by id like:

$(function(){
  $("#input-select2").select2();
});

I think i understand what the reason of your error. First you click auto AUTO INCREMENT field then select it as a primary key.

The Right way is First You have to select it as a primary key then you have to click auto AUTO INCREMENT field.

Very easy. Thanks

In ChildVC this worked for me...

self.navigationController.navigationBar.topItem.title = @"Back";

Works in Swift too!

self.navigationController!.navigationBar.topItem!.title = "Back"

Private Function GetIPv4Address() As String

The simplest Hello World example...

$hello = "Hello World"
$hello | Out-File c:\debug.txt

Here's a flow chart that illustrates a for loop:

The equivalent C code would be

for(i = 2; i <= 6; i = i + 2) {
    printf("%d\t", i + 1);
}

I found this and several other examples on one of Tenouk's C Laboratory practice worksheets.

Or even easier and without the need to create a filter: use PHP's mb_strimwidth to truncate a string to a certain width (length). Just make sure you use one of the get_ syntaxes. For example with the content:

<?php $content = get_the_content(); echo mb_strimwidth($content, 0, 400, '...');?>

This will cut the string at 400 characters and close it with .... Just add a "read more"-link to the end by pointing to the permalink with get_permalink().

<a href="<?php the_permalink() ?>">Read more </a>

Of course you could also build the read more in the first line. Than just replace '...' with '<a href="' . get_permalink() . '">[Read more]</a>'

The general rule of thumb is that you don't modify a collection/array/list while iterating over it.

Use a secondary list to store the items you want to act upon and execute that logic in a loop after your initial loop.

A quick update: since Typescript 2.1 there is a built in type Record<T, K> that acts like a dictionary.

In this case you could declare stuff like so:

var stuff: Record<string, any> = {};

You could also limit/specify potential keys by unioning literal types:

var stuff: Record<'a'|'b'|'c', string|boolean> = {};

Here's a more generic example using the record type from the docs:

// For every properties K of type T, transform it to U
function mapObject<K extends string, T, U>(obj: Record<K, T>, f: (x: T) => U): Record<K, U>

const names = { foo: "hello", bar: "world", baz: "bye" };
const lengths = mapObject(names, s => s.length);  // { foo: number, bar: number, baz: number }

TypeScript 2.1 Documentation on Record<T, K>

The only disadvantage I see to using this over {[key: T]: K} is that you can encode useful info on what sort of key you are using in place of "key" e.g. if your object only had prime keys you could hint at that like so: {[prime: number]: yourType}.

Here's a regex I wrote to help with these conversions. This will only convert cases where the label is "key". To convert other labels simply change the first capturing group:

Find: \{\s*\[(key)\s*(+\s*:\s*(\w+)\s*\]\s*:\s*([^\}]+?)\s*;?\s*\}

Replace: Record<$2, $3>

In Typescript use the For Each like below.

selectChildren(data, $event) {
let parentChecked = data.checked;
for(var obj in this.hierarchicalData)
    {
        for (var childObj in obj )
        {
            value.checked = parentChecked;
        }
    }
}

You can achieve this using the location object.

location.href = "http://someurl"; 

Basically, if you're on a 64-bit machine, IIS 7 is not (by default) serving 32-bit apps, which the database engine operates on. So here is exactly what you do:

1) ensure that the 2007 database engine is installed, this can be downloaded at: http://www.microsoft.com/downloads/details.aspx?FamilyID=7554F536-8C28-4598-9B72-EF94E038C891&displaylang=en

2) open IIS7 manager, and open the Application Pools area. On the right sidebar, you will see an option that says "Set application pool defaults". Click it, and a window will pop up with the options.

3) the second field down, which says 'Enable 32-bit applications' is probably set to FALSE by default. Simply click where it says 'false' to change it to 'true'.

4) Restart your app pool (you can do this by hitting RECYCLE instead of STOP then START, which will also work).

5) done, and your error message will go away.

How about this: (or is it ok to use like this?)

var test = "Hello";
new Thread(new ThreadStart(() =>
{
    try
    {
        //Staff to do
        Console.WriteLine(test);
    }
    catch (Exception ex)
    {
        throw;
    }
})).Start();

I would do it this way:

(function($) {
jQuery.fn.doSomething = function() {
   return this.each(function() {
      var $this = $(this);

      $this.click(function(event) {
         event.preventDefault();
         // Your function goes here
      });
   });
};
})(jQuery);

Then on document ready you can do stuff like this:

$(document).ready(function() {
   $('#div1').doSomething();
   $('#div2').doSomething();
});

labelTV.setGravity(Gravity.CENTER | Gravity.BOTTOM);

Kotlin version (thanks to Thommy)

labelTV.gravity = Gravity.CENTER_HORIZONTAL or Gravity.BOTTOM

Also, are you talking about gravity or about layout_gravity? The latter won't work in a RelativeLayout.

Maybe because you have a tag like a parent of the tag. That why you have to click two time the images.

For me the solution is this: http://www.w3schools.com/js/tryit.asp?filename=tryjs_intro_lightbulb

Hy, In my case this error appeared because the Application pool of the webservice had the wrong 32/64 bit setting. So this error needed the following fix: you go to the IIS, select the site of the webservice , go to Advanced setting and get the application pool. Then go to Application pools, select it, go to "Advanced settings..." , select the "Enable 32 bit applications" and make it Enable or Disable, according to the 32/64 bit type of your webservice. If the setting is True, it means that it only allows 32 bit applications, so for 64 bit apps you have to make it "Disable" (default).

This function is way faster than a for loop for filling an array.

The Array.Copy command is a very fast memory copy function. This function takes advantage of that by repeatedly calling the Array.Copy command and doubling the size of what we copy until the array is full.

I discuss this on my blog at https://grax32.com/2013/06/fast-array-fill-function-revisited.html (Link updated 12/16/2019). Also see Nuget package that provides this extension method. http://sites.grax32.com/ArrayExtensions/

Note that this would be easy to make into an extension method by just adding the word "this" to the method declarations i.e. public static void ArrayFill<T>(this T[] arrayToFill ...

public static void ArrayFill<T>(T[] arrayToFill, T fillValue)
{
    // if called with a single value, wrap the value in an array and call the main function
    ArrayFill(arrayToFill, new T[] { fillValue });
}

public static void ArrayFill<T>(T[] arrayToFill, T[] fillValue)
{
    if (fillValue.Length >= arrayToFill.Length)
    {
        throw new ArgumentException("fillValue array length must be smaller than length of arrayToFill");
    }

    // set the initial array value
    Array.Copy(fillValue, arrayToFill, fillValue.Length);

    int arrayToFillHalfLength = arrayToFill.Length / 2;

    for (int i = fillValue.Length; i < arrayToFill.Length; i *= 2)
    {
        int copyLength = i;
        if (i > arrayToFillHalfLength)
        {
            copyLength = arrayToFill.Length - i;
        }

        Array.Copy(arrayToFill, 0, arrayToFill, i, copyLength);
    }
}

For me, on centOS 7 I had to remove the old pip link from /bin by

rm /bin/pip2.7 
rm /bin/pip

then relink it with

sudo ln -s  /usr/local/bin/pip2.7 /bin/pip2.7

Then if

/usr/local/bin/pip2.7

Works, this should work

I did a small URL library for my needs here: https://github.com/Mikhus/jsurl

It's a more common way of manipulating the URLs in JavaScript. Meanwhile it's really lightweight (minified and gzipped < 1 KB) and has a very simple and clean API. And it does not need any other library to work.

Regarding the initial question, it's very simple to do:

var u = new Url; // Current document URL
// or
var u = new Url('http://user:[email protected]:8080/some/path?foo=bar&bar=baz#anchor');

// Looking for query string parameters
alert( u.query.bar);
alert( u.query.foo);

// Modifying query string parameters
u.query.foo = 'bla';
u.query.woo = ['hi', 'hey']

alert(u.query.foo);
alert(u.query.woo);
alert(u);

Maybe I'm missing something, but wouldn't this suffice:

if (view instanceof B) {
    // this view is an instance of B
}

The Visual Studio debugger comes with four standard visualizers. These are the text, HTML, and XML visualizers, all of which work on string objects, and the dataset visualizer, which works for DataSet, DataView, and DataTable objects.

To use it, break into your code, mouse over your DataSet, expand the quick watch, view the Tables, expand that, then view Table[0] (for example). You will see something like {Table1} in the quick watch, but notice that there is also a magnifying glass icon. Click on that icon and your DataTable will open up in a grid view.

I've solved this problem using JDK 7 with this code:

package FileCreationDate;

import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.attribute.BasicFileAttributes;
import java.util.Date;
import java.util.concurrent.TimeUnit;

public class Main
{
    public static void main(String[] args) {

        File file = new File("c:\\1.txt");
        Path filePath = file.toPath();

        BasicFileAttributes attributes = null;
        try
        {
            attributes =
                    Files.readAttributes(filePath, BasicFileAttributes.class);
        }
        catch (IOException exception)
        {
            System.out.println("Exception handled when trying to get file " +
                    "attributes: " + exception.getMessage());
        }
        long milliseconds = attributes.creationTime().to(TimeUnit.MILLISECONDS);
        if((milliseconds > Long.MIN_VALUE) && (milliseconds < Long.MAX_VALUE))
        {
            Date creationDate =
                    new Date(attributes.creationTime().to(TimeUnit.MILLISECONDS));

            System.out.println("File " + filePath.toString() + " created " +
                    creationDate.getDate() + "/" +
                    (creationDate.getMonth() + 1) + "/" +
                    (creationDate.getYear() + 1900));
        }
    }
}

I know of plotyy that allows you to have two y-axes, but no "plotyyy"!

Perhaps you can normalize the y values to have the same scale (min/max normalization, zscore standardization, etc..), then you can just easily plot them using normal plot, hold sequence.

Here's an example:

%# random data
x=1:20;
y = [randn(20,1)*1 + 0 , randn(20,1)*5 + 10 , randn(20,1)*0.3 + 50];

%# plotyy
plotyy(x,y(:,1), x,y(:,3))

%# orginial
figure
subplot(221), plot(x,y(:,1), x,y(:,2), x,y(:,3))
title('original'), legend({'y1' 'y2' 'y3'})

%# normalize: (y-min)/(max-min) ==> [0,1]
yy = bsxfun(@times, bsxfun(@minus,y,min(y)), 1./range(y));
subplot(222), plot(x,yy(:,1), x,yy(:,2), x,yy(:,3))
title('minmax')

%# standarize: (y - mean) / std ==> N(0,1)
yy = zscore(y);
subplot(223), plot(x,yy(:,1), x,yy(:,2), x,yy(:,3))
title('zscore')

%# softmax normalization with logistic sigmoid ==> [0,1]
yy = 1 ./ ( 1 + exp( -zscore(y) ) );
subplot(224), plot(x,yy(:,1), x,yy(:,2), x,yy(:,3))
title('softmax')

The command pm clear com.android.browser requires root permission.
So, run su first.

Here is the sample code:

private static final String CHARSET_NAME = "UTF-8";
String cmd = "pm clear com.android.browser";

ProcessBuilder pb = new ProcessBuilder().redirectErrorStream(true).command("su");
Process p = pb.start();

// We must handle the result stream in another Thread first
StreamReader stdoutReader = new StreamReader(p.getInputStream(), CHARSET_NAME);
stdoutReader.start();

out = p.getOutputStream();
out.write((cmd + "\n").getBytes(CHARSET_NAME));
out.write(("exit" + "\n").getBytes(CHARSET_NAME));
out.flush();

p.waitFor();
String result = stdoutReader.getResult();

The class StreamReader:

import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.concurrent.CountDownLatch;

class StreamReader extends Thread {
    private InputStream is;
    private StringBuffer mBuffer;
    private String mCharset;
    private CountDownLatch mCountDownLatch;

    StreamReader(InputStream is, String charset) {
        this.is = is;
        mCharset = charset;
        mBuffer = new StringBuffer("");
        mCountDownLatch = new CountDownLatch(1);
    }

    String getResult() {
        try {
            mCountDownLatch.await();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        return mBuffer.toString();
    }

    @Override
    public void run() {
        InputStreamReader isr = null;
        try {
            isr = new InputStreamReader(is, mCharset);
            int c = -1;
            while ((c = isr.read()) != -1) {
                mBuffer.append((char) c);
            }

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                if (isr != null)
                    isr.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
            mCountDownLatch.countDown();
        }
    }
}

Add Unique Index on your table:

ALTER IGNORE TABLE `TableA`   
ADD UNIQUE INDEX (`member_id`, `quiz_num`, `question_num`, `answer_num`);

Another way to do this would be:

Add primary key in your table then you can easily remove duplicates from your table using the following query:

DELETE FROM member  
WHERE id IN (SELECT * 
             FROM (SELECT id FROM member 
                   GROUP BY member_id, quiz_num, question_num, answer_num HAVING (COUNT(*) > 1)
                  ) AS A
            );

I think that you are looking for something like this:

   function rightclick() {
    var rightclick;
    var e = window.event;
    if (e.which) rightclick = (e.which == 3);
    else if (e.button) rightclick = (e.button == 2);
    alert(rightclick); // true or false, you can trap right click here by if comparison
}

(http://www.quirksmode.org/js/events_properties.html)

And then use the onmousedown even with the function rightclick() (if you want to use it globally on whole page you can do this <body onmousedown=rightclick(); >

It seems that there are circular references in your object hierarchy which is not supported by the JSON serializer. Do you need all the columns? You could pick up only the properties you need in the view:

return Json(new 
{  
    PropertyINeed1 = data.PropertyINeed1,
    PropertyINeed2 = data.PropertyINeed2
});

This will make your JSON object lighter and easier to understand. If you have many properties, AutoMapper could be used to automatically map between DTO objects and View objects.

Pick one depends on the method you are looking for!?

I will go with ParentNode.children:

As it provides namedItem method that allows me directly to get one of the children elements without looping through all children or avoiding to use getElementById etc.

e.g.

ParentNode.children.namedItem('ChildElement-ID'); // JS
ref.current.children.namedItem('ChildElement-ID'); // React
this.$refs.ref.children.namedItem('ChildElement-ID'); // Vue

I will go with Node.childNodes:

As it provides forEach method when I work with window.IntersectionObserver e.g.

nodeList.forEach((node) => { observer.observe(node) })
// IE11 does not support forEach on nodeList, but easy to be polyfilled.

On Chrome 83

Node.childNodes provides entries, forEach, item, keys, length and values

ParentNode.children provides item, length and namedItem
