Let's say you have an associative array like this:

$a = array(
    "one" => 1,
    "two" => 2,
    "three" => 3,
    "seventeen" => array('x'=>123)
);

In the first iteration : $key="one" and $value=1.

Sometimes you need this key ,if you want only the value , you can avoid using it.

In the last iteration : $key='seventeen' and $value = array('x'=>123) so to get value of the first element in this array value, you need a key, x in this case: $value['x'] =123.

If someone is wondering how to work with multidimensional object, here is the solution.

lets assume we have following object in service

getChallenges() {
    var objects = {};
    objects['0'] = { 
        title: 'Angular2', 
        description : "Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur."
    };

    objects['1'] = { 
        title: 'AngularJS', 
        description : "Lorem Ipsum is simply dummy text of the printing and typesetting industry."
    };

    objects['2'] = { 
        title: 'Bootstrap',
        description : "Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.",
    };
    return objects;
}

in component add following function

challenges;

constructor(testService : TestService){
    this.challenges = testService.getChallenges();
}
keys() : Array<string> {
    return Object.keys(this.challenges);
}

finally in view do following

<div *ngFor="#key of keys();">
    <h4 class="heading">{{challenges[key].title}}</h4>
    <p class="description">{{challenges[key].description}}</p>
</div>

Embed is not a standard tag, though object is. Here's an article that looks like it will help you, since it seems the situation is not so simple. An example for PDF is included.

another solution is to add toggle=false to the collapse target, this will stop it randomly opening and closing which happens if you just remove the "in"

eg

<div class="accordion-heading">
    <a class="accordion-toggle"
        data-toggle="collapse"
        data-parent="#accordion2"
        href="#collapseOne">Open!</a>
</div>
<div
    id="collapseOne"
    class="accordion-body collapse"
    data-toggle="false"
    >
    <div class="span6">
        <div class="well well-small">
            <div class="accordion-toggle">
                ...some text...
            </div>
        </div>
    </div>
    <div class="span2"></div>                            
</div>

1. the best way to delete a record is to find it firstly (if exist in data base in the same time you want to delete it)
2. watch this code

const StudentSequelize = require("../models/studientSequelize");
const StudentWork = StudentSequelize.Student;

const id = req.params.id;
    StudentWork.findByPk(id) // here i fetch result by ID sequelize V. 5
    .then( resultToDelete=>{
        resultToDelete.destroy(id); // when i find the result i deleted it by destroy function
    })
    .then( resultAfterDestroy=>{
        console.log("Deleted :",resultAfterDestroy);
    })
    .catch(err=> console.log(err));

I know this question already has answers but I will give my solution to this problem. I am using template function and integer constraint on it.

Here is my solution:

#include <type_traits>
#include <vector>

template <typename T,
          typename std::enable_if<std::is_arithmetic<T>::value>::type* = nullptr>
std::vector<uint8_t> splitValueToBytes(T const& value)
{
    std::vector<uint8_t> bytes;

    for (size_t i = 0; i < sizeof(value); i++)
    {
        uint8_t byte = value >> (i * 8);
        bytes.insert(bytes.begin(), byte);
    }

    return bytes;
}

working like a charm here for bootstrap 4>4.1.1

var myGroup = $('your-list');

myGroup.on('show.bs.collapse','.collapse', function() {
   myGroup.find('.collapse.show').collapse('hide');
});

Use ifstream to read data from a file:

std::ifstream input( "filename.ext" );

If you really need to read line by line, then do this:

for( std::string line; getline( input, line ); )
{
    ...for each line in input...
}

But you probably just need to extract coordinate pairs:

int x, y;
input >> x >> y;

Update:

In your code you use ofstream myfile;, however the o in ofstream stands for output. If you want to read from the file (input) use ifstream. If you want to both read and write use fstream.

Another approach :

Find the propertie with the max m2_price withing each program (n properties in 1 program) :

select * from properties p
join (
    select max(m2_price) as max_price 
    from properties 
    group by program_id
) p2 on (p.program_id = p2.program_id)
having p.m2_price = max_price

It looks like the DOCTYPE is causing the image to display as an inline element. If I add display: block to the image, problem solved.

ERROR = Command CompileSwiftSources failed with a nonzero exit code

In my case When I found this error, I got cramped with compilation. But when I see some related problem answers. I found a duplication file on my project. Where the same viewController was there as a class file. So yeah when I realized it I changed it name to new one. And yeah things changed!!!

worked for me too:

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
    Date parsed = null;
    try {
        parsed = sdf.parse("02/01/2014");
    } catch (ParseException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    java.sql.Date data = new java.sql.Date(parsed.getTime());
    contato.setDataNascimento( data);

    // Contato DataNascimento era Calendar
    //contato.setDataNascimento(Calendar.getInstance());         

    // grave nessa conexão!!! 
    ContatoDao dao = new ContatoDao("mysql");           

    // método elegante 
    dao.adiciona(contato); 
    System.out.println("Banco: ["+dao.getNome()+"] Gravado! Data: "+contato.getDataNascimento());

I would rather make it like this

<video  id="v1" width="320" height="240" controls="controls">

</video>

and then use

$("#v1").html('<source src="test1.mp4" type="video/mp4"></source>' );

The main difference between these two is that ConcurrentHashMap will lock only portion of the data which are being updated while other portion of data can be accessed by other threads. However, Collections.synchronizedMap() will lock all the data while updating, other threads can only access the data when the lock is released. If there are many update operations and relative small amount of read operations, you should choose ConcurrentHashMap.

Also one other difference is that ConcurrentHashMap will not preserve the order of elements in the Map passed in. It is similar to HashMap when storing data. There is no guarantee that the element order is preserved. While Collections.synchronizedMap() will preserve the elements order of the Map passed in. For example, if you pass a TreeMap to ConcurrentHashMap, the elements order in the ConcurrentHashMap may not be the same as the order in the TreeMap, but Collections.synchronizedMap() will preserve the order.

Furthermore, ConcurrentHashMap can guarantee that there is no ConcurrentModificationException thrown while one thread is updating the map and another thread is traversing the iterator obtained from the map. However, Collections.synchronizedMap() is not guaranteed on this.

There is one post which demonstrate the differences of these two and also the ConcurrentSkipListMap.

function getDefaultDate(curDate){
var dt = new Date(curDate);`enter code here`
var date = dt.getDate();
var month = dt.getMonth();
var year = dt.getFullYear();
if (month.toString().length == 1) {
    month = "0" + month
}
if (date.toString().length == 1) {
    date = "0" + date
}
return year.toString() + "-" + month.toString() + "-" + date.toString();
}

In function pass your date string.

The curses package in python can be used to enter "raw" mode for character input from the terminal with just a few statements. Curses' main use is to take over the screen for output, which may not be what you want. This code snippet uses print() statements instead, which are usable, but you must be aware of how curses changes line endings attached to output.

#!/usr/bin/python3
# Demo of single char terminal input in raw mode with the curses package.
import sys, curses

def run_one_char(dummy):
    'Run until a carriage return is entered'
    char = ' '
    print('Welcome to curses', flush=True)
    while ord(char) != 13:
        char = one_char()

def one_char():
    'Read one character from the keyboard'
    print('\r? ', flush= True, end = '')

    ## A blocking single char read in raw mode. 
    char = sys.stdin.read(1)
    print('You entered %s\r' % char)
    return char

## Must init curses before calling any functions
curses.initscr()
## To make sure the terminal returns to its initial settings,
## and to set raw mode and guarantee cleanup on exit. 
curses.wrapper(run_one_char)
print('Curses be gone!')

With Bootstrap you can simply use class text-center:

<div class="container">
    <div class="row">
        <form>
            <input class="input-xxlarge" type="text" placeholder="Email..">
        </form>

        <div class="text-center">
            <button type="submit" class="btn">Confirm</button>
        </div>
    </div>
</div>

if anyone needs to extract the first part of the string then can try,

Query:

$s = "This_is_a_string_233718";

$text = $s."_".substr($s, 0, strrpos($s, "_"));

Output:

This_is_a_string

Here is the code to check whether value is present or not.

If Trim(textbox1.text) <> "" Then
     'Your code goes here
Else
     'Nothing
End If

I think this will help.

A HashSet has an internal structure (hash), where items can be searched and identified quickly. The downside is that iterating through a HashSet (or getting an item by index) is rather slow.

So why would someone want be able to know if an entry already exists in a set?

One situation where a HashSet is useful is in getting distinct values from a list where duplicates may exist. Once an item is added to the HashSet it is quick to determine if the item exists (Contains operator).

Other advantages of the HashSet are the Set operations: IntersectWith, IsSubsetOf, IsSupersetOf, Overlaps, SymmetricExceptWith, UnionWith.

If you are familiar with the object constraint language then you will identify these set operations. You will also see that it is one step closer to an implementation of executable UML.

I found this question while trying to make a dictionary out of three columns of a pandas dataframe. In my case the dataframe has columns A, B and C (let's say A and B are the geographical coordinates of longitude and latitude and C the country region/state/etc, which is more or less the case).

I wanted a dictionary with each pair of A,B values (dictionary key) matching the value of C (dictionary value) in the corresponding row (each pair of A,B values is guaranteed to be unique due to previous filtering, but it is possible to have the same value of C for different pairs of A,B values in this context), so I did:

mydict = dict(zip(zip(df['A'],df['B']), df['C']))

Using pandas to_dict() also works:

mydict = df.set_index(['A','B']).to_dict(orient='dict')['C']

(none of the columns A or B were used as index before executing the line creating the dictionary)

Both approaches are fast (less than one second on a dataframe with 85k rows, 5-year-old fast dual-core laptop).

The reasons I'm posting this:

1. for those who need this kind of solution
2. if someone knows a faster executing solution (e.g., for millions of rows), I'd appreciate a reply.

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

In Ultra Edit and Crimson (or Emerald) Editor you can enable/disable the column mode with Alt + C

No, that's not possible. The port is not part of the hostname, so it has no meaning in the hosts-file.

It turns it into a bytes literal (or str in 2.x), and is valid for 2.6+.

The r prefix causes backslashes to be "uninterpreted" (not ignored, and the difference does matter).

null is not an object, it is a primitive value. For example, you cannot add properties to it. Sometimes people wrongly assume that it is an object, because typeof null returns "object". But that is actually a bug (that might even be fixed in ECMAScript 6).

The difference between null and undefined is as follows:

• undefined: used by JavaScript and means “no value”. Uninitialized variables, missing parameters and unknown variables have that value.

  > var noValueYet;
  > console.log(noValueYet);
  undefined
  
  > function foo(x) { console.log(x) }
  > foo()
  undefined
  
  > var obj = {};
  > console.log(obj.unknownProperty)
  undefined
  

  Accessing unknown variables, however, produces an exception:

  > unknownVariable
  ReferenceError: unknownVariable is not defined
  

• null: used by programmers to indicate “no value”, e.g. as a parameter to a function.

Examining a variable:

console.log(typeof unknownVariable === "undefined"); // true

var foo;
console.log(typeof foo === "undefined"); // true
console.log(foo === undefined); // true

var bar = null;
console.log(bar === null); // true

As a general rule, you should always use === and never == in JavaScript (== performs all kinds of conversions that can produce unexpected results). The check x == null is an edge case, because it works for both null and undefined:

> null == null
true
> undefined == null
true

A common way of checking whether a variable has a value is to convert it to boolean and see whether it is true. That conversion is performed by the if statement and the boolean operator ! (“not”).

function foo(param) {
    if (param) {
        // ...
    }
}
function foo(param) {
    if (! param) param = "abc";
}
function foo(param) {
    // || returns first operand that can't be converted to false
    param = param || "abc";
}

Drawback of this approach: All of the following values evaluate to false, so you have to be careful (e.g., the above checks can’t distinguish between undefined and 0).

• undefined, null
• Booleans: false
• Numbers: +0, -0, NaN
• Strings: ""

You can test the conversion to boolean by using Boolean as a function (normally it is a constructor, to be used with new):

> Boolean(null)
false
> Boolean("")
false
> Boolean(3-3)
false
> Boolean({})
true
> Boolean([])
true

"o" format is different for DateTime vs DateTimeOffset :(

DateTime.UtcNow.ToString("o") -> "2016-03-09T03:30:25.1263499Z"

DateTimeOffset.UtcNow.ToString("o") -> "2016-03-09T03:30:46.7775027+00:00"

My final answer is

DateTimeOffset.UtcDateTime.ToString("o")   //for DateTimeOffset type
DateTime.UtcNow.ToString("o")              //for DateTime type

Most probably you want to use a method

<span>{{ fullName('Hi') }}</span>

methods: {
  fullName(salut) {
      return `${salut} ${this.firstName} ${this.lastName}`
  }
}

Longer explanation

Technically you can use a computed property with a parameter like this:

computed: {
   fullName() {
      return salut => `${salut} ${this.firstName} ${this.lastName}`
   }
}

(Thanks Unirgy for the base code for this.)

The difference between a computed property and a method is that computed properties are cached and change only when their dependencies change. A method will evaluate every time it's called.

If you need parameters, there are usually no benefits of using a computed property function over a method in such a case. Though it allows you to have a parametrized getter function bound to the Vue instance, you lose caching so not really any gain there, in fact, you may break reactivity (AFAIU). You can read more about this in Vue documentation https://vuejs.org/v2/guide/computed.html#Computed-Caching-vs-Methods

The only useful situation is when you have to use a getter and need to have it parametrized. For instance, this situation happens in Vuex. In Vuex it's the only way to synchronously get parametrized result from the store (actions are async). Thus this approach is listed by official Vuex documentation for its getters https://vuex.vuejs.org/guide/getters.html#method-style-access

Assign the onclick like this:

divTag.onclick = printWorking;

The onclick property will not take a string when assigned. Instead, it takes a function reference (in this case, printWorking).
The onclick attribute can be a string when assigned in HTML, e.g. <div onclick="func()"></div>, but this is generally not recommended.

This code works for me:

import groovy.io.FileType

def list = []

def dir = new File("path_to_parent_dir")
dir.eachFileRecurse (FileType.FILES) { file ->
  list << file
}

Afterwards the list variable contains all files (java.io.File) of the given directory and its subdirectories:

list.each {
  println it.path
}

Have a look at localize, or l

eg:

l Time.at(1100897479)

What you want to do is a combination of part of 1 and all of 2.

You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.

But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.

From the javadoc:

Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.

The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.

Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:

import static org.mockito.Mockito.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

class ClassWithStatics {
  public static String getString() {
    return "String";
  }

  public static int getInt() {
    return 1;
  }
}

@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
  @Test
  public void test() {
    PowerMockito.mockStatic(ClassWithStatics.class);

    when(ClassWithStatics.getString()).thenReturn("Hello!");

    System.out.println("String: " + ClassWithStatics.getString());
    System.out.println("Int: " + ClassWithStatics.getInt());
  }
}

The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.

If you move from iframes, you may get lost in your page, best way to execute some jquery without issue (with selenimum/python/gecko):

# 1) Get back to the main body page
driver.switch_to.default_content()

# 2) Download jquery lib file to your current folder manually & set path here
with open('./_lib/jquery-3.3.1.min.js', 'r') as jquery_js: 
    # 3) Read the jquery from a file
    jquery = jquery_js.read() 
    # 4) Load jquery lib
    driver.execute_script(jquery)
    # 5) Execute your command 
    driver.execute_script('$("#myId").click()')

This is actually coming very late, but I thought I should share,

in index.html

<script type="text/javascript" src="1.js"></script>
<script type="text/javascript" src="2.js"></script>

in 1.js

fn1 = function() {
    alert("external fn clicked");
}

in 2.js

fn1()

1. You can set it as background-image and use text-indent or a padding to shift the text to the right.
2. You can break it up into two elements.

Honestly, I would avoid usage of HTML5/CSS3 without a good fallback. There are just too many people using old browsers that don't support all the new fancy stuff. It will take a while before we can drop the fallback, unfortunately :(

The first method I mentioned is the safest and easiest. Both ways requires Javascript to hide the icon.

CSS:

input#search {
    background-image: url(bg.jpg);
    background-repeat: no-repeat;
    text-indent: 20px;
}

HTML:

<input type="text" id="search" name="search" onchange="hideIcon(this);" value="search" />

Javascript:

function hideIcon(self) {
    self.style.backgroundImage = 'none';
}

September 25h, 2013

I can't believe I said "Both ways requires JavaScript to hide the icon.", because this is not entirely true.

The most common timing to hide placeholder text is on change, as suggested in this answer. For icons however it's okay to hide them on focus which can be done in CSS with the active pseudo-class.

#search:active { background-image: none; }

Heck, using CSS3 you can make it fade away!

http://jsfiddle.net/2tTxE/

November 5th, 2013

Of course, there's the CSS3 ::before pseudo-elements too. Beware of browser support though!

            Chrome  Firefox     IE      Opera   Safari
:before     (yes)   1.0         8.0     4       4.0
::before    (yes)   1.5         9.0     7       4.0

https://developer.mozilla.org/en-US/docs/Web/CSS/::before

If you mean "non-alphanumeric characters", try to use this:

var reg =/[^a-zA-Z0-9]/g      //[^abc]

if ($string =~ m/something/) {
   # Do work
}

Where something is a regular expression.

I highly suggest you to use an array instead of an object if you're doing react itteration, this is a syntax I use it ofen.

const rooms = this.state.array.map((e, i) =>(<div key={i}>{e}</div>))

To use the element, just place {rooms} in your jsx.

Where e=elements of the arrays and i=index of the element. Read more here. If your looking for itteration, this is the way to do it.

well you can do this:

$(function(){

    var $header = $('#header');
    var $footer = $('#footer');
    var $content = $('#content');
    var $window = $(window).on('resize', function(){
       var height = $(this).height() - $header.height() + $footer.height();
       $content.height(height);
    }).trigger('resize'); //on page load

});

see fiddle here: http://jsfiddle.net/maniator/JVKbR/
demo: http://jsfiddle.net/maniator/JVKbR/show/

you have to iterate gridview Rows

for (int count = 0; count < grd.Rows.Count; count++)
{
    if (((CheckBox)grd.Rows[count].FindControl("yourCheckboxID")).Checked)
    {     
      ((Label)grd.Rows[count].FindControl("labelID")).Text
    }
}

This was critical to get this to work with Entity Framework:

var genericCollection = list as ICollection<T>;

if (genericCollection != null)
{
   //your code 
}

I know I'm a bit late to this, but in case you wanted to perform relative padding (aka edge padding), here's how you can implement it. Note that the very first instance of assignment results in zero-padding, so you can use this for both zero-padding and relative padding (this is where you copy the edge values of the original array into the padded array).

def replicate_padding(arr):
    """Perform replicate padding on a numpy array."""
    new_pad_shape = tuple(np.array(arr.shape) + 2) # 2 indicates the width + height to change, a (512, 512) image --> (514, 514) padded image.
    padded_array = np.zeros(new_pad_shape) #create an array of zeros with new dimensions
    
    # perform replication
    padded_array[1:-1,1:-1] = arr        # result will be zero-pad
    padded_array[0,1:-1] = arr[0]        # perform edge pad for top row
    padded_array[-1, 1:-1] = arr[-1]     # edge pad for bottom row
    padded_array.T[0, 1:-1] = arr.T[0]   # edge pad for first column
    padded_array.T[-1, 1:-1] = arr.T[-1] # edge pad for last column
    
    #at this point, all values except for the 4 corners should have been replicated
    padded_array[0][0] = arr[0][0]     # top left corner
    padded_array[-1][0] = arr[-1][0]   # bottom left corner
    padded_array[0][-1] = arr[0][-1]   # top right corner 
    padded_array[-1][-1] = arr[-1][-1] # bottom right corner

    return padded_array

Complexity Analysis:

The optimal solution for this is numpy's pad method. After averaging for 5 runs, np.pad with relative padding is only 8% better than the function defined above. This shows that this is fairly an optimal method for relative and zero-padding padding.

#My method, replicate_padding
start = time.time()
padded = replicate_padding(input_image)
end = time.time()
delta0 = end - start

#np.pad with edge padding
start = time.time()
padded = np.pad(input_image, 1, mode='edge')
end = time.time()
delta = end - start


print(delta0) # np Output: 0.0008790493011474609 
print(delta)  # My Output: 0.0008130073547363281
print(100*((delta0-delta)/delta)) # Percent difference: 8.12316715542522%

find $HOME -name "hello.c" -print

This will search the whole $HOME (i.e. /home/username/) system for any files named “hello.c” and display their pathnames:

/Users/user/Downloads/hello.c
/Users/user/hello.c

However, it will not match HELLO.C or HellO.C. To match is case insensitive pass the -iname option as follows:

find $HOME -iname "hello.c" -print

Sample outputs:

/Users/user/Downloads/hello.c
/Users/user/Downloads/Y/Hello.C
/Users/user/Downloads/Z/HELLO.c
/Users/user/hello.c

Pass the -type f option to only search for files:

find /dir/to/search -type f -iname "fooBar.conf.sample" -print
find $HOME -type f -iname "fooBar.conf.sample" -print

The -iname works either on GNU or BSD (including OS X) version find command. If your version of find command does not supports -iname, try the following syntax using grep command:

find $HOME | grep -i "hello.c"
find $HOME -name "*" -print | grep -i "hello.c"

OR try

find $HOME -name '[hH][eE][lL][lL][oO].[cC]' -print

Sample outputs:

/Users/user/Downloads/Z/HELLO.C
/Users/user/Downloads/Z/HEllO.c
/Users/user/Downloads/hello.c
/Users/user/hello.c

You have change proper version of the JAVA_HOME and PATH in environmental variables.

• First you need to create HubNode(Server) and start the HubNode(Server) from command Line/prompt using Java: -jar selenium-server-standalone-2.44.0.jar -role hub
• Then bind the node/Client to this Hub using Hub machines IPAddress or Name with any port number >1024. For Node Machine for example: Java -jar selenium-server-standalone-2.44.0.jar -role webdriver -hub http://HubmachineIPAddress:4444/grid/register -port 5566

One more thing is that whenever we use Internet Explore or Google Chrome we need to set: System.setProperty("webdriver.ie.driver",path);

The usage of both can be depended on the structure of your data.

Simply, You can use the Nested Objects approach if you plan to give priority to a unique identifier such as a Primary Key.

eg:

  {
     "Employees" : {
           "001" : {
               "Name" : "Alan",
               "Children" : ["Walker", "Dua", "Lipa"]
                },
           "002" : {
               "Name" : "Ezio",
               "Children" : ["Kenvey", "Connor", "Edward"]
                }
      }

Or, Use the Array first approach if you intend to store a set of values with no need to identify uniquely.

eg:

 [
     {
        "Employees":[
               {
                   "Name" : "Alan",
                   "Children" : ["Walker", "Dua", "Lipa"]
               },
               {
                   "Name" : "Ezio",
                   "Children" : ["Kenvey", "Connor", "Edward"]
               }
          ]
       }
   ]

Although you could use the second method with an identifier, it can be harder or too complex to query and understand in some scenarios. Also depending on the database one may have to apply a suitable approach. Eg: MongoDB / Firebase

@Jonathan: I could be mistaken, but I believe that String.valueOf() in this case will call the String.valueOf(Object) function rather than getting boxed to String.valueOf(int). String.valueOf(Object) just returns "null" if it is null or calls Object.toString() if non-null, which shouldn't involve boxing (although obviously instantiating new string objects is involved).

$("input#A").attr("myattr") == null

Check if the text you're trying to append to the node is not escaped like this:

var prop = {
    match: {
        description: '<h1>Hi there!</h1>'
    }
};

Instead of this:

var prop = {
    match: {
        description: '<h1>Hi there!</h1>'
    }
};

if is escaped you should convert it from your server-side.

The node is text because is escaped

The node is a dom node because isn't escaped

Many people spend a lot of time changing labels, legend labels, titles and the names of the axis because they don't know it is possible to load tables in R that contains spaces " ". You can however do this to save time or reduce the size of your code, by specifying the separators when you load a table that is for example delimited with tabs (or any other separator than default or a single space):

read.table(sep = '\t')

or by using the default loading parameters of the csv format:

read.csv()

This means you can directly keep the name "NEW LEGEND TITLE" as a column name (header) in your original data file to avoid specifying a new legend title in every plot.

You can use System.arraycopy().

int[] source = new int[1000];

int[] part1 = new int[500];
int[] part2 = new int[500];

//              (src   , src-offset  , dest , offset, count)
System.arraycopy(source, 0           , part1, 0     , part1.length);
System.arraycopy(source, part1.length, part2, 0     , part2.length);

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

I know the OP is asking for a CSS-only solution. But in case anyone landing here from the Magic Google ends up requiring a JavaScript solution, here's a one-liner:

capitalize = str => str[0].toUpperCase() + str.substr(1);

e.g.:

capitalize('foo bar baz'); // -> 'Foo bar baz'

This is because, the amount of memory you wish to assign for JVM is not available or may be you are assigning more than available memory. Try small size then u can see the difference.
Try:

set JAVA_OPTS=-Xms128m -Xmx512m -XX:PermSize=128m

The most useful thing you can do here is display/i $pc, before using stepi as already suggested in R Samuel Klatchko's answer. This tells gdb to disassemble the current instruction just before printing the prompt each time; then you can just keep hitting Enter to repeat the stepi command.

(See my answer to another question for more detail - the context of that question was different, but the principle is the same.)

Using Bash Parameter Expansion:

orig="AxxBCyyyDEFzzLMN"
mod=${orig//[xyz]/_}

I wrapped around $state around $timeout and it worked for me.

For example,

(function() {
  'use strict';

  angular
    .module('app')
    .controller('BodyController', BodyController);

  BodyController.$inject = ['$state', '$timeout'];

  /* @ngInject */
  function BodyController($state, $timeout) {
    $timeout(function(){
      console.log($state.current);
    });

  }
})();

You can do timer.Interval = timer.Interval

NodeJS, at one point (I think it was v0.6.x) had ArrayBuffer support. I created a small library for base64 encoding and decoding here, but since updating to v0.7, the tests (on NodeJS) fail. I'm thinking of creating something that normalizes this, but till then, I suppose Node's native Buffer should be used.

I would do something like this for the code you showed, if all you need to do is toggle a value :

var oddClick = true;
$("#time").click(function() {
    $(this).animate({
        width: oddClick ? 260 : 30
    },1500);
    oddClick = !oddClick;
});

git revert HEAD -m 1

In the above code line. "Last argument represents"

• 1 - reverts one commits. 2 - reverts last commits. n - reverts last n commits

or

git reset --hard siriwjdd

By default, it's not in your PATH. You need to use the "Visual Studio 2005 Command Prompt". Alternatively, you can run the vsvars32 batch file, which will set up your environment correctly.

Conveniently, the path to this is stored in the VS80COMNTOOLS environment variable.

You can use this code to bind click an element which is in iframe.

jQuery('.class_in_iframe',jQuery('[id="id_of_iframe"]')[0].contentWindow.document.body).on('click',function(){ _x000D_
 console.log("triggered !!")_x000D_
});

adb shell killall -9 com.your.package.name

according to MAC "mandatory access control" you probably have the permission to kill process which is not started by root

have fun!

To do this, I had to come up with an intermediate data structure:

class KeyDataPoint {
    String key;
    DateTime timestamp;
    Number data;
    // obvious constructor and getters
}

With this in place, the approach is to "flatten" each MultiDataPoint into a list of (timestamp, key, data) triples and stream together all such triples from the list of MultiDataPoint.

Then, we apply a groupingBy operation on the string key in order to gather the data for each key together. Note that a simple groupingBy would result in a map from each string key to a list of the corresponding KeyDataPoint triples. We don't want the triples; we want DataPoint instances, which are (timestamp, data) pairs. To do this we apply a "downstream" collector of the groupingBy which is a mapping operation that constructs a new DataPoint by getting the right values from the KeyDataPoint triple. The downstream collector of the mapping operation is simply toList which collects the DataPoint objects of the same group into a list.

Now we have a Map<String, List<DataPoint>> and we want to convert it to a collection of DataSet objects. We simply stream out the map entries and construct DataSet objects, collect them into a list, and return it.

The code ends up looking like this:

Collection<DataSet> convertMultiDataPointToDataSet(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.getData().entrySet().stream()
                           .map(e -> new KeyDataPoint(e.getKey(), mdp.getTimestamp(), e.getValue())))
        .collect(groupingBy(KeyDataPoint::getKey,
                    mapping(kdp -> new DataPoint(kdp.getTimestamp(), kdp.getData()), toList())))
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

I took some liberties with constructors and getters, but I think they should be obvious.

You can fire the event simply with

document.getElementById("elementID").onchange();

I dont know if this doesnt work on some browsers, but it should work on FF 3 and IE 7+

For installing pip with get-pip.py behind a proxy I went with the steps below. My server was even behind a jump server.

From the jump server:

ssh -R 18080:proxy-server:8080 my-python-server

On the "python-server"

export https_proxy=https://localhost:18080 ; export http_proxy=http://localhost:18080 ; export ftp_proxy=$http_proxy
python get-pip.py

Success.

You need to specify which column of the datarow you want to pull data from.

Try the following:

        StringBuilder output = new StringBuilder();
        foreach (DataRow rows in results.Tables[0].Rows)
        {
            foreach (DataColumn col in results.Tables[0].Columns)
            {
                output.AppendFormat("{0} ", rows[col]);
            }

            output.AppendLine();
        }

For me, the trick was extraData and drilling down into the item component one more time

state = {
  uniqueValue: 0
}

<FlatList
  keyExtractor={(item, index) => item + index}
  data={this.props.photos}
  renderItem={this.renderItem}
  ItemSeparatorComponent={this.renderSeparator}
/>

renderItem = (item) => {
  if(item.item.selected) {
    return ( <Button onPress={this.itemPressed.bind(this, item)}>Selected</Button> );
  }
  return ( <Button onPress={this.itemPressed.bind(this, item)}>Not selected</Button>);
}

itemPressed (item) {
  this.props.photos.map((img, i) => {
    if(i === item.index) {
      if(img['selected') {
        delete img.selected;
      } else {
        img['selected'] = true;
      }
      this.setState({ uniqueValue: this.state.uniqueValue +1 });
    }
  }
}

Try this

$('#D25,#E37,#E31,#F37,#E16,#E40,#F16,#F40,#E41,#F41').bind('DOMNodeInserted DOMNodeRemoved',function(){
          // your code;
       });

Do not use this. This may crash the page.

$('mydiv').bind("DOMSubtreeModified",function(){
  alert('changed');
});

The request type is multipart/form-data and what you are sending is essentially form fields that go out as bytes with content boundaries separating different form fields.To send an object representation as form field (string), you can send a serialized form from the client that you can then deserialize on the server.

After all no programming environment object is actually ever traveling on the wire. The programming environment on both side are just doing automatic serialization and deserialization that you can also do. That is the cleanest and programming environment quirks free way to do it.

As an example, here is a javascript client posting to a Jersey example service,

submitFile(){

    let data = new FormData();
    let account = {
        "name": "test account",
        "location": "Bangalore"
    }

    data.append('file', this.file);
    data.append("accountKey", "44c85e59-afed-4fb2-884d-b3d85b051c44");
    data.append("device", "test001");
    data.append("account", JSON.stringify(account));
    
    let url = "http://localhost:9090/sensordb/test/file/multipart/upload";

    let config = {
        headers: {
            'Content-Type': 'multipart/form-data'
        }
    }

    axios.post(url, data, config).then(function(data){
        console.log('SUCCESS!!');
        console.log(data.data);
    }).catch(function(){
        console.log('FAILURE!!');
    });
},

Here the client is sending a file, 2 form fields (strings) and an account object that has been stringified for transport. here is how the form fields look on the wire,

On the server, you can just deserialize the form fields the way you see fit. To finish this trivial example,

    @POST
@Path("/file/multipart/upload")
@Consumes({MediaType.MULTIPART_FORM_DATA})
public Response uploadMultiPart(@Context ContainerRequestContext requestContext,
        @FormDataParam("file") InputStream fileInputStream,
        @FormDataParam("file") FormDataContentDisposition cdh,
        @FormDataParam("accountKey") String accountKey,
        @FormDataParam("account") String json)  {
    

    
    System.out.println(cdh.getFileName());
    System.out.println(cdh.getName());
    System.out.println(accountKey);
    
    try {
        Account account = Account.deserialize(json);
        System.out.println(account.getLocation());
        System.out.println(account.getName());
        
    } catch (Exception e) {
        e.printStackTrace();
    }
    
    return Response.ok().build();
    
}

Putting comments on the same line with commands: use & :: comment

color C          & :: set red font color
echo IMPORTANT INFORMATION
color            & :: reset the color to default

Explanation:

& separates two commands, so in this case color C is the first command and :: set red font color is the second one.

Important:

This statement with comment looks intuitively correct:

goto error1         :: handling the error

but it is not a valid use of the comment. It works only because goto ignores all arguments past the first one. The proof is easy, this goto will not fail either:

goto error1 handling the error

But similar attempt

color 17            :: grey on blue

fails executing the command due to 4 arguments unknown to the color command: ::, grey, on, blue.

It will only work as:

color 17     &      :: grey on blue

So the ampersand is inevitable.

On a side note, in PowerShell 3.0 you can use the Get-Content cmdlet with the new Raw switch:

$text = Get-Content .\file.txt -Raw 

I know that is really old question, but found pretty easy to remember, fast command to kill app that are using port.

Requirements: [email protected]^ version

npx kill-port 8080

ASP.Net applications come pre-wired with a handlers section in the web.config. By default, this is set to readonly within feature delegation within IIS. Take a look in IIS Manager

1.Go to IIS Manager and click Server Name

2.Go to the section Management and click Feature Delegation.

3.Select the Handler Mappings which is supposed to set as readonly.

4.Change the value to read/write and now you can get resolved the issue

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

declare @ID table (ID int)

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

OK, you should apply something like this to your dataset. Do not replace & save or you'll destroy your data! And, btw, you should (almost) never remove outliers from your data:

remove_outliers <- function(x, na.rm = TRUE, ...) {
  qnt <- quantile(x, probs=c(.25, .75), na.rm = na.rm, ...)
  H <- 1.5 * IQR(x, na.rm = na.rm)
  y <- x
  y[x < (qnt[1] - H)] <- NA
  y[x > (qnt[2] + H)] <- NA
  y
}

To see it in action:

set.seed(1)
x <- rnorm(100)
x <- c(-10, x, 10)
y <- remove_outliers(x)
## png()
par(mfrow = c(1, 2))
boxplot(x)
boxplot(y)
## dev.off()

And once again, you should never do this on your own, outliers are just meant to be! =)

EDIT: I added na.rm = TRUE as default.

EDIT2: Removed quantile function, added subscripting, hence made the function faster! =)

In .Net through version 4 this can be done the same way as for SQL Server Stored Procs but note that you need:

using System.Data.OracleClient;

There are some system requirements here that you should verify are OK in your scenario.

Microsoft is deprecating this namespace as of .Net 4 so third-party providers will be needed in the future. With this in mind, you may be better off using Oracle Data Provider for .Net (ODP.NET) from the word go - this has optimizations that are not in the Microsoft classes. There are other third-party options, but Oracle has a strong vested interest in keeping .Net developers on board so theirs should be good.

None of the answers worked with me, but after reading all of them, I figured out what was the issue in my case I have 1 Html page that I want to print but it was printing with it an extra white blank page. I am using AdminLTE a bootstrap 3 theme for the page of the report to print and in it the footer tag I wanted to place this text to the bottom right of the page:

Printed by Mr. Someone

I used jquery to put that text instead of the previous "Copy Rights" footer with

$("footer").html("Printed by Mr. Someone");

and by default in the theme the tag footer uses the class .main-footer which has the attributes

padding: 15px;
border-top: 1px solid 

that caused an extra white space, so after knowing the issue, I had different options, and the best option was to use

$( "footer" ).removeClass( "main-footer" );

Just in that specific page

The output of head -10 file can be piped to grep in order to accomplish this:

head -10 file | grep …

Using Perl:

perl -ne 'last if $. > 10; print if /pattern/' file

Below is the python function to do the same.

def sigmoid(x) :
    return 1.0/(1+np.exp(-x))

The []s in a regex denote a character class. If no ranges are specified, it implicitly ors every character within it together. Thus, [abcde] is the same as (a|b|c|d|e), except that it doesn't capture anything; it will match any one of a, b, c, d, or e. All a range indicates is a set of characters; [ac-eg] says "match any one of: a; any character between c and e; or g". Thus, your match says "match any one of: 0; any character between 1 and 1 (i.e., just 1); or 2.

Your goal is evidently to specify a number range: any number between 01 and 12 written with two digits. In this specific case, you can match it with 0[1-9]|1[0-2]: either a 0 followed by any digit between 1 and 9, or a 1 followed by any digit between 0 and 2. In general, you can transform any number range into a valid regex in a similar manner. There may be a better option than regular expressions, however, or an existing function or module which can construct the regex for you. It depends on your language.

The same can be done without DataTrigger too:

 <DataGrid.RowStyle>
     <Style TargetType="DataGridRow">
         <Setter Property="Background" >
             <Setter.Value>
                 <Binding Path="State" Converter="{StaticResource BooleanToBrushConverter}">
                     <Binding.ConverterParameter>
                         <x:Array Type="SolidColorBrush">
                             <SolidColorBrush Color="{StaticResource RedColor}"/>
                             <SolidColorBrush Color="{StaticResource TransparentColor}"/>
                         </x:Array>
                     </Binding.ConverterParameter>
                 </Binding>
             </Setter.Value>
         </Setter>
     </Style>
 </DataGrid.RowStyle>

Where BooleanToBrushConverter is the following class:

public class BooleanToBrushConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value == null)
            return Brushes.Transparent;

        Brush[] brushes = parameter as Brush[];
        if (brushes == null)
            return Brushes.Transparent;

        bool isTrue;
        bool.TryParse(value.ToString(), out isTrue);

        if (isTrue)
        {
            var brush =  (SolidColorBrush)brushes[0];
            return brush ?? Brushes.Transparent;
        }
        else
        {
            var brush = (SolidColorBrush)brushes[1];
            return brush ?? Brushes.Transparent;
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

--Gets the size of each index for the specified table

    INNER JOIN sys.dm_db_partition_stats AS s 
        ON i.[object_id] = s.[object_id] AND i.index_id = s.index_id
WHERE s.[object_id] = OBJECT_ID(@TableName, N'U')
GROUP BY i.name
ORDER BY i.name;

SELECT i.name AS IndexName
      ,8 * SUM(a.used_pages) AS IndexSizeKB

        ON p.partition_id = a.container_id
WHERE i.[object_id] = OBJECT_ID(@TableName, N'U')
GROUP BY i.name
ORDER BY i.name;

This should work:

window.onload = function() {
  document.getElementById('about').className = 'expand';
};

Or if you're using jQuery:

$(function() {
  $('#about').addClass('expand');
});

See Input and Ouput:

with open('filename') as f:
    lines = f.readlines()

or with stripping the newline character:

with open('filename') as f:
    lines = [line.rstrip() for line in f]

.NET 4.5 is not a side-by-side version, it replaces the assemblies for 4.0. Much like .NET 3.0, 3.5 and 3.5SP1 replaced the assemblies for 2.0. And added some new ones. The CLR version is still 4.0.30319. You only care about the reference assemblies, they are in c:\program files\reference assemblies.

This works for me compiled based on what was said here with a more modern standard. This works best for multiple looks up.

let element = document.querySelectorAll('.myClass')
  element.forEach(item => {
    console.log(item.innerHTML = item.innerText || item.textContent)
  })

You can make a template function, and pass the array by reference to achieve this.

Here is my code snippet

template <typename TypeOfData>


void PrintArray(TypeOfData &arrayOfType);

int main()

{

    char charArray[] = "my name is";

    int intArray[] = { 1,2,3,4,5,6 };

    double doubleArray[] = { 1.1,2.2,3.3 };


    PrintArray(charArray);

    PrintArray(intArray);

    PrintArray(doubleArray);

}


template <typename TypeOfData>

void PrintArray(TypeOfData &arrayOfType)

{

    int elementsCount = sizeof(arrayOfType) / sizeof(arrayOfType[0]);


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

    {

        cout << "Value in elements at position " << i + 1 << " is " << arrayOfType[i] << endl;

    }

}

OpenSSH has been added to Windows as of autumn 2018, and is included in Windows 10 and Windows Server 2019.

So you can use it in command prompt or power shell like bellow.

C:\Users\Parsa>scp [email protected]:/etc/cassandra/cassandra.yaml F:\Temporary

One easy way is to drag and drop. It will copy files to /sdcard/Download. You can copy whole folders or multiple files. Make sure that "Enable Clipboard Sharing" is enabled. (under ...->Settings)

For me this happened within a class function.

In PHP 5.3 and above $this::$defaults worked fine; when I swapped the code into a server that for whatever reason had a lower version number it threw this error.

The solution, in my case, was to use the keyword self instead of $this:

self::$defaults works just fine.

renderItem(item)
  {
    const width = '80%';
    var items = [];

    for(let i = 0; i < item.count; i++){

        items.push( <View style={{ padding: 10, borderBottomColor: "#f2f2f2", borderBottomWidth: 10, flexDirection: 'row' }}>
    <View style={{ width }}>
      <Text style={styles.name}>{item.title}</Text>
      <Text style={{ color: '#818181', paddingVertical: 10 }}>{item.taskDataElements[0].description + " "}</Text>
      <Text style={styles.begin}>BEGIN</Text>
    </View>

    <Text style={{ backgroundColor: '#fcefec', padding: 10, color: 'red', height: 40 }}>{this.msToTime(item.minTatTimestamp) <= 0 ? "NOW" : this.msToTime(item.minTatTimestamp) + "hrs"}</Text>
  </View> )
  }

  return items;
}

render() {
return (this.renderItem(this.props.item)) 
}

You can adjust pandas print options with set_printoptions.

However this will not work in all cases as pandas detects your console width and it will only use to_string if the output fits in the console (see the docstring of set_printoptions). In this case you can explicitly call to_string as answered by BrenBarn.

Not being a developer I found a solution in running multiple ps commands in one line. E.g:

powershell "& 'c:\path with spaces\to\executable.exe' -arguments ; second command ; etc

By placing a " (double quote) before the & (ampersand) it executes the executable. In none of the examples I have found this was mentioned. Without the double quotes the ps prompt opens and waits for input.

With procrun you need to copy prunsrv to the application directory (download), and create an install.bat like this:

set PR_PATH=%CD%
SET PR_SERVICE_NAME=MyService
SET PR_JAR=MyService.jar
SET START_CLASS=org.my.Main
SET START_METHOD=main
SET STOP_CLASS=java.lang.System
SET STOP_METHOD=exit
rem ; separated values
SET STOP_PARAMS=0
rem ; separated values
SET JVM_OPTIONS=-Dapp.home=%PR_PATH%
prunsrv.exe //IS//%PR_SERVICE_NAME% --Install="%PR_PATH%\prunsrv.exe" --Jvm=auto --Startup=auto --StartMode=jvm --StartClass=%START_CLASS% --StartMethod=%START_METHOD% --StopMode=jvm --StopClass=%STOP_CLASS% --StopMethod=%STOP_METHOD% ++StopParams=%STOP_PARAMS% --Classpath="%PR_PATH%\%PR_JAR%" --DisplayName="%PR_SERVICE_NAME%" ++JvmOptions=%JVM_OPTIONS%

I presume to

• run this from the same directory where the jar and prunsrv.exe is
• the jar has its working MANIFEST.MF
• and you have shutdown hooks registered into JVM (for example with context.registerShutdownHook() in Spring)...
• not using relative paths for files outside the jar (for example log4j should be used with log4j.appender.X.File=${app.home}/logs/my.log or something alike)

Check the procrun manual and this tutorial for more information.

You can use (PHP)

$isFan = file_get_contents("https://api.facebook.com/method/pages.isFan?format=json&access_token=" . USER_TOKEN . "&page_id=" . FB_FANPAGE_ID);

That will return one of three:

• string true string false json
• formatted response of error if token
• or page_id are not valid

I guess the only not-using-token way to achieve this is with the signed_request Jason Siffring just posted. My helper using PHP SDK:

function isFan(){
    global $facebook;
    $request = $facebook->getSignedRequest();
    return $request['page']['liked'];
}

Just use:

pwd | xargs basename

or

basename "`pwd`"

The angular documentation for select* does not answer this question explicitly, but it is there. If you look at the script.js, you will see this:

function MyCntrl($scope) {
  $scope.colors = [
    {name:'black', shade:'dark'},
    {name:'white', shade:'light'},
    {name:'red', shade:'dark'},
    {name:'blue', shade:'dark'},
    {name:'yellow', shade:'light'}
  ];
  $scope.color = $scope.colors[2]; // Default the color to red
}

This is the html:

<select ng-model="color" ng-options="c.name for c in colors"></select>

This seems to be a more obvious way of defaulting a selected value on an <select> with ng-options. Also it will work if you have different label/values.

* This is from Angular 1.2.7

If you're on Debian 8 (Jessie) Linux, try to cd into the directory of the 'metropolises.sql'. Run mysql and execute SOURCE ./metropolises.sql;

Basically, try the relative path. I tried this and it works.

CSS properties should be set by cssText property or setAttribute method.

// Set multiple styles in a single statement
elt.style.cssText = "color: blue; border: 1px solid black"; 
// Or
elt.setAttribute("style", "color:red; border: 1px solid blue;");

Styles should not be set by assigning a string directly to the style property (as in elt.style = "color: blue;"), since it is considered read-only, as the style attribute returns a CSSStyleDeclaration object which is also read-only.

If you're still wondering how to solve it.

I use

$protected $dates = ['created_at','updated_at','aired'];

In my model and in my where i do

where('aired','>=',time())

So just use the unix to compaire in where.

In views on the otherhand you have to use the date object.

Hope it helps someone!

Use this code if you are facing text trimming problem while applying padding.

@IBDesignable class PaddingLabel: UILabel {

    @IBInspectable var topInset: CGFloat = 5.0
    @IBInspectable var bottomInset: CGFloat = 5.0
    @IBInspectable var leftInset: CGFloat = 5.0
    @IBInspectable var rightInset: CGFloat = 5.0

    override func drawText(in rect: CGRect) {
        let insets = UIEdgeInsets.init(top: topInset, left: leftInset, bottom: bottomInset, right: rightInset)
        super.drawText(in: UIEdgeInsetsInsetRect(rect, insets))
    }

    override var intrinsicContentSize: CGSize {
        var intrinsicSuperViewContentSize = super.intrinsicContentSize
        let textWidth = frame.size.width - (self.leftInset + self.rightInset)
        let newSize = self.text!.boundingRect(with: CGSize(textWidth, CGFloat.greatestFiniteMagnitude), options: NSStringDrawingOptions.usesLineFragmentOrigin, attributes: [NSFontAttributeName: self.font], context: nil)
        intrinsicSuperViewContentSize.height = ceil(newSize.size.height) + self.topInset + self.bottomInset
        return intrinsicSuperViewContentSize
    }
}

extension CGSize{
    init(_ width:CGFloat,_ height:CGFloat) {
        self.init(width:width,height:height)
    }
}

It wont work since you use URL link with "file://". Instead you should match your directory to your HTML file, for example:

Lets say my file placed in:

C:/myuser/project/file.html

And my wanted image is in:

C:/myuser/project2/image.png

All I have to do is matching the directory this way:

<img src="../project2/image.png" />

I'd use inheritance. Especially if there are going to be more differences than number of holes. Especially if Gouda will need to have different set of members then Parmesan.

class Gouda(Cheese):
    def __init__(self):
        super(Gouda).__init__(num_holes=10)


class Parmesan(Cheese):
    def __init__(self):
        super(Parmesan).__init__(num_holes=15) 

If you mean File.separator and File.pathSeparator then:

• File.pathSeparator is used to separate individual file paths in a list of file paths. Consider on windows, the PATH environment variable. You use a ; to separate the file paths so on Windows File.pathSeparator would be ;.

• File.separator is either / or \ that is used to split up the path to a specific file. For example on Windows it is \ or C:\Documents\Test

For the OP's command:

select compid,2, convert(datetime, '01/01/' + CONVERT(char(4),cal_yr) ,101) ,0,  Update_dt, th1, th2, th3_pc , Update_id, Update_dt,1
from  #tmp_CTF** 

I get this error:

Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '*'.

when debugging something like this split the long line up so you'll get a better row number:

select compid
,2
, convert(datetime
, '01/01/' 
+ CONVERT(char(4)
,cal_yr) 
,101) 
,0
,  Update_dt
, th1
, th2
, th3_pc 
, Update_id
, Update_dt
,1
from  #tmp_CTF** 

this now results in:

Msg 102, Level 15, State 1, Line 16
Incorrect syntax near '*'.

which is probably just from the OP not putting the entire command in the question, or use [ ] braces to signify the table name:

from [#tmp_CTF**]

if that is the table name.

I tried to send/add input tag's values into JavaScript variable which worked well for me, here is the code:

<!DOCTYPE html>
<html>
    <head>
        <script type="text/javascript">
            function changef()
            {
            var ctext=document.getElementById("c").value;

            document.writeln(ctext);
            }

        </script>
    </head>
    <body>
        <input type="text" id="c" onchange="changef"();>

        <button type="button" onclick="changef()">click</button>
    </body> 
</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>).

ObservableCollection is a collection that allows code outside the collection be aware of when changes to the collection (add, move, remove) occur. It is used heavily in WPF and Silverlight but its use is not limited to there. Code can add event handlers to see when the collection has changed and then react through the event handler to do some additional processing. This may be changing a UI or performing some other operation.

The code below doesn't really do anything but demonstrates how you'd attach a handler in a class and then use the event args to react in some way to the changes. WPF already has many operations like refreshing the UI built in so you get them for free when using ObservableCollections

class Handler
{
    private ObservableCollection<string> collection;

    public Handler()
    {
        collection = new ObservableCollection<string>();
        collection.CollectionChanged += HandleChange;
    }

    private void HandleChange(object sender, NotifyCollectionChangedEventArgs e)
    {
        foreach (var x in e.NewItems)
        {
            // do something
        }

        foreach (var y in e.OldItems)
        {
            //do something
        }
        if (e.Action == NotifyCollectionChangedAction.Move)
        {
            //do something
        }
    }
}

The other answers are outdated. The behavior of Chrome for window.open depends on where it is called from. See also this topic.

When window.open is called from a handler that was triggered though a user action (e.g. onclick event), it will behave similar as <a target="_blank">, which by default opens in a new tab. However if window.open is called elsewhere, Chrome ignores other arguments and always opens a new window with a non-editable address bar.

This looks like some kind of security measure, although the rationale behind it is not completely clear.

Install using pip install pycompyle6

pycompyle6 filename.pyc

in C++ expression a % b returns remainder of division of a by b (if they are positive. For negative numbers sign of result is implementation defined). For example:

5 % 2 = 1
13 % 5 = 3

With this knowledge we can try to understand your code. Condition count % 6 == 5 means that newline will be written when remainder of division count by 6 is five. How often does that happen? Exactly 6 lines apart (excercise : write numbers 1..30 and underline the ones that satisfy this condition), starting at 6-th line (count = 5).

To get desired behaviour from your code, you should change condition to count % 5 == 4, what will give you newline every 5 lines, starting at 5-th line (count = 4).

Kinda late.But it just takes a bit of math.

.content {
  margin-top: 50px;
  background: #777;
  padding: 30px;
  padding-bottom: 0;
  font-size: 11px;
  border: 1px dotted #222;
}

.bottom-content {
  background: #999;
  width: 100%; /* you need this for it to work */
  margin-left: -30px; /* will touch very left side */
  padding-right: 60px; /* will touch very right side */
}

<div class='content'>

  <p>A paragraph</p>
  <p>Another paragraph.</p>
  <p>No more content</p>


  <div class='bottom-content'>
      I want this div to ignore padding.
  </div>

I don't have Windows so I didn't test this in IE.

fiddle: fiddle example..

You can use $0 to determine your script name (with full path) - to get the script name only you can trim that variable with

basename $0

With the window.location object. This code gives you GET without the question mark.

window.location.search.substr(1)

From your example it will return returnurl=%2Fadmin

EDIT: I took the liberty of changing Qwerty's answer, which is really good, and as he pointed I followed exactly what the OP asked:

function findGetParameter(parameterName) {
    var result = null,
        tmp = [];
    location.search
        .substr(1)
        .split("&")
        .forEach(function (item) {
          tmp = item.split("=");
          if (tmp[0] === parameterName) result = decodeURIComponent(tmp[1]);
        });
    return result;
}

I removed the duplicated function execution from his code, replacing it a variable ( tmp ) and also I've added decodeURIComponent, exactly as OP asked. I'm not sure if this may or may not be a security issue.

Or otherwise with plain for loop, which will work even in IE8:

function findGetParameter(parameterName) {
    var result = null,
        tmp = [];
    var items = location.search.substr(1).split("&");
    for (var index = 0; index < items.length; index++) {
        tmp = items[index].split("=");
        if (tmp[0] === parameterName) result = decodeURIComponent(tmp[1]);
    }
    return result;
}

You want the path.join() function from os.path.

>>> from os import path
>>> path.join('foo', 'bar')
'foo/bar'

This builds your path with os.sep (instead of the less portable '/') and does it more efficiently (in general) than using +.

However, this won't actually create the path. For that, you have to do something like what you do in your question. You could write something like:

start_path = '/my/root/directory'
final_path = os.join(start_path, *list_of_vars)
if not os.path.isdir(final_path):
    os.makedirs (final_path)

Though post is a bit old, I would like to say the following. Issue I had with above solution is that it does not filter out characters like ç, ë, ï, etc. I adapted a function as follows (I only used an 80 varchar string to save memory):

create FUNCTION dbo.udf_Cleanchars (@InputString varchar(80)) 
RETURNS varchar(80) 
AS 

BEGIN

If you have java 8 installed it might be related to the following issue: https://support.oracle.com/knowledge/Middleware/2412304_1.html

Simply removing/renaming the "C:\Program Files (x86)\Common Files\Oracle\Java\javapath" worked for me.

You are placing your result in the RETURN value instead of in the passed @rvalue.

From MSDN

(RETURN) Is the integer value that is returned. Stored procedures can return an integer value to a calling procedure or an application.

Changing your procedure.

ALTER procedure S_Comp(@str1 varchar(20),@r varchar(100) out) as 

    declare @str2 varchar(100) 
    set @str2 ='welcome to sql server. Sql server is a product of Microsoft' 
    if(PATINDEX('%'+@str1 +'%',@str2)>0) 
        SELECT @r =  @str1+' present in the string' 
    else 
        SELECT @r = @str1+' not present'

Calling the procedure

  DECLARE @r VARCHAR(100)
  EXEC S_Comp 'Test', @r OUTPUT
  SELECT @r

Since you already have an answer to what's wrong with your code, I can bring another perspective on how you can play with datetimes generally, and solve your problem specifically.

Oftentimes you find yourself posing a problem in terms of solution. This is just one of the reasons you end up with an imperative code. It's great if it works though; there are just other, arguably more maintainable alternatives. One of them is a declarative code. The point is asking what you need, instead of how to get there.

In your particular case, this can look like the following. First, you need to find out what is it that you're looking for, that is, discover abstractions. In your case, it looks like you need a date. Not just any date, but the one having some standard representation. Say, ISO8601 date. There are at least two implementations: the first one is a date parsed from an ISO8601-formatted string (or a string in any other format actually), and the second is some future date which is a day later. Thus, the whole code could look like that:

(new Future(
    new DateTimeParsedFromISO8601('2009-09-30 20:24:00'),
    new OneDay()
))
    ->value();

Since 12,200 people have looked at this question and not got an answer:

DFSORT and SyncSort are the predominant Mainframe sorting products. Their control cards have many similarities, and some differences.

JOINKEYS FILE=F1,FIELDS=(key1startpos,7,A)              
JOINKEYS FILE=F2,FIELDS=(key2startpos,7,A)              
JOIN UNPAIRED,F1,F2
REFORMAT FIELDS=(F1:1,5200,F2:1,5200)                         
SORT FIELDS=COPY    

A "JOINKEYS" is made of three Tasks. Sub-Task 1 is the first JOINKEYS. Sub-Task 2 is the second JOINKEYS. The Main Task follows and is where the joined data is processed. In the example above it is a simple COPY operation. The joined data will simply be written to SORTOUT.

The JOIN statement defines that as well as matched records, UNPAIRED F1 and F2 records are to be presented to the Main Task.

The REFORMAT statement defines the record which will be presented to the Main Task. A more efficient example, imagining that three fields are required from F2, is:

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100)

Each of the fields on F2 is defined with a start position and a length.

The record which is then processed by the Main task is 5311 bytes long, and the fields from F2 can be referenced by 5201,10,5211,1,5212,100 with the F1 record being 1,5200.

A better way achieve the same thing is to reduce the size of F2 with JNF2CNTL.

//JNF2CNTL DD *
  INREC BUILD=(207,1,10,30,1,5100,100)

Some installations of SyncSort do not support JNF2CNTL, and even where supported (from Syncsort MFX for z/OS release 1.4.1.0 onwards), it is not documented by SyncSort. For users of 1.3.2 or 1.4.0 an update is available from SyncSort to provide JNFnCNTL support.

It should be noted that JOINKEYS by default SORTs the data, with option EQUALS. If the data for a JOINKEYS file is already in sequence, SORTED should be specified. For DFSORT NOSEQCHK can also be specified if sequence-checking is not required.

 JOINKEYS FILE=F1,FIELDS=(key1startpos,7,A),SORTED,NOSEQCHK

Although the request is strange, as the source file won't be able to be determined, all unmatched records are to go to a separate output file.

With DFSORT, there is a matching-marker, specified with ? in the REFORMAT:

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100,?)

This increases the length of the REFORMAT record by one byte. The ? can be specified anywhere on the REFORMAT record, and need not be specified. The ? is resolved by DFSORT to: B, data sourced from Both files; 1, unmatched record from F1; 2, unmatched record from F2.

SyncSort does not have the match marker. The absence or presence of data on the REFORMAT record has to be determined by values. Pick a byte on both input records which cannot contain a particular value (for instance, within a number, decide on a non-numeric value). Then specify that value as the FILL character on the REFORMAT.

 REFORMAT FIELDS=(F1:1,5200,F2:1,10,30,1,5100,100),FILL=C'$'

If position 1 on F1 cannot naturally have "$" and position 20 on F2 cannot either, then those two positions can be used to establish the result of the match. The entire record can be tested if necessary, but sucks up more CPU time.

The apparent requirement is for all unmatched records, from either F1 or F2, to be written to one file. This will require a REFORMAT statement which includes both records in their entirety:

DFSORT, output unmatched records:

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200,?)

  OUTFIL FNAMES=NOMATCH,INCLUDE=(10401,1,SS,EQ,C'1,2'),
        IFTHEN=(WHEN=(10401,1,CH,EQ,C'1'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

SyncSort, output unmatched records:

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200),FILL=C'$'

  OUTFIL FNAMES=NOMATCH,INCLUDE=(1,1,CH,EQ,C'$',
                          OR,5220,1,CH,EQ,C'$'),
        IFTHEN=(WHEN=(1,1,CH,EQ,C'$'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

The coding for SyncSort will also work with DFSORT.

To get the matched records written is easy.

  OUTFIL FNAMES=MATCH,SAVE

SAVE ensures that all records not written by another OUTFIL will be written here.

There is some reformatting required, to mainly output data from F1, but to select some fields from F2. This will work for either DFSORT or SyncSort:

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

The whole thing, with arbitrary starts and lengths is:

DFSORT

  JOINKEYS FILE=F1,FIELDS=(1,7,A)              
  JOINKEYS FILE=F2,FIELDS=(20,7,A)    

  JOIN UNPAIRED,F1,F2

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200,?)                         

  SORT FIELDS=COPY    

  OUTFIL FNAMES=NOMATCH,INCLUDE=(10401,1,SS,EQ,C'1,2'),
        IFTHEN=(WHEN=(10401,1,CH,EQ,C'1'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

SyncSort

  JOINKEYS FILE=F1,FIELDS=(1,7,A)              
  JOINKEYS FILE=F2,FIELDS=(20,7,A)              

  JOIN UNPAIRED,F1,F2

  REFORMAT FIELDS=(F1:1,5200,F2:1,5200),FILL=C'$'                         

  SORT FIELDS=COPY    

  OUTFIL FNAMES=NOMATCH,INCLUDE=(1,1,CH,EQ,C'$',
                          OR,5220,1,CH,EQ,C'$'),
        IFTHEN=(WHEN=(1,1,CH,EQ,C'$'),
                    BUILD=(1,5200)),
        IFTHEN=(WHEN=NONE,
                    BUILD=(5201,5200))

  OUTFIL FNAMES=MATCH,SAVE,
     BUILD=(1,50,10300,100,51,212,5201,10,263,8,5230,1,271,4929)

This is a modified version of Simons answer which makes the multi-lined output a single line. It also introduces the current timestamp so it's easier to follow each line of output.

I used the above to catch slow responses on the above endpoint.

You need to use an ObjectMapper:

ObjectMapper mapper = new ObjectMapper();
JsonFactory factory = mapper.getJsonFactory(); // since 2.1 use mapper.getFactory() instead
JsonParser jp = factory.createJsonParser("{\"k1\":\"v1\"}");
JsonNode actualObj = mapper.readTree(jp);

Further documentation about creating parsers can be found here.

If you're wondering how to get the file content from each ZipEntry it's actually quite simple. Here's a sample code:

public static void main(String[] args) throws IOException {
    ZipFile zipFile = new ZipFile("C:/test.zip");

    Enumeration<? extends ZipEntry> entries = zipFile.entries();

    while(entries.hasMoreElements()){
        ZipEntry entry = entries.nextElement();
        InputStream stream = zipFile.getInputStream(entry);
    }
}

Once you have the InputStream you can read it however you want.

AppCompat v7+

If you don't prefix with ?android: your app will crash.

You should use "?android:attr/selectableItemBackground" or "?android:attr/selectableItemBackgroundBorderless", based on your preference. I prefer Borderless.

You can put it either in android:background or android:foreground to keep existing properties.

The element must have android:clickable="true" and android:focusable="true" in order for this to work, but many elements, such as buttons, have them true by default.

<Button
    ...
    android:background="@color/white"
    android:foreground="?android:attr/selectableItemBackgroundBorderless"
/>
<TextView
    ...
    android:background="?android:attr/selectableItemBackgroundBorderless"
    android:clickable="true"
    android:focusable="true"
/>

Programmatically (Java)

TypedValue value = new TypedValue();
context.getTheme().resolveAttribute(android.R.attr.selectableItemBackground, value, true);
myView.setBackgroundResource(value.resourceId);
myView.setFocusable(true); // If needed for view type

Programmatically (Kotlin)

val value = TypedValue()
context.theme.resolveAttribute(android.R.attr.selectableItemBackground, value, true)
myView.setBackgroundResource(value.resourceId)
myView.setFocusable(true) // If needed for view type

Reusable Kotlin Extension Function

myView.ripple()

fun View.ripple(): View {
    val value = TypedValue()
    context.theme.resolveAttribute(android.R.attr.selectableItemBackground, value, true)
    setBackgroundResource(value.resourceId)
    isFocusable = true // Required for some view types
    return this
}

.panel-default >.panel-heading
{
    background: #ffffff;
}

This is what worked for me to change the color to white.

Also note, if you have explicitly granted:

CONNECT ON DATABASE xxx TO GROUP ,

you will need to revoke this separately from DROP OWNED BY, using:

REVOKE CONNECT ON DATABASE xxx FROM GROUP

Navigate to your flavor of .Net and CPU architecture directory using CMD or powershell

Enter this command: aspnet_regiis –r

Thing is $@ will include the entire (relative) path to the source file which is in turn used to construct the object name (and thus its relative path)

We use:

#####################
# rules to build the object files
$(OBJDIR_1)/%.o: %.c
    @$(ECHO) "$< -> $@"
    @test -d $(OBJDIR_1) || mkdir -pm 775 $(OBJDIR_1)
    @test -d $(@D) || mkdir -pm 775 $(@D)
    @-$(RM) $@
    $(CC) $(CFLAGS) $(CFLAGS_1) $(ALL_FLAGS) $(ALL_DEFINES) $(ALL_INCLUDEDIRS:%=-I%) -c $< -o $@

This creates an object directory with name specified in $(OBJDIR_1) and subdirectories according to subdirectories in source.

For example (assume objs as toplevel object directory), in Makefile:

widget/apple.cpp
tests/blend.cpp

results in following object directory:

objs/widget/apple.o
objs/tests/blend.o

If you want to import a specific function or class from a module, you can do this:

import importlib
import sys
importlib.reload(sys.modules['my_module'])
from my_module import my_function

1 Step - Install a required extension

sudo apt-get install libz-dev -y

2 Step - Install the PHP extension

pecl install zlib zip

3 Step - Restart your Apache

sudo /etc/init.d/apache2 restart

If does not work you can check if the zip.ini is called in your phpinfo, to check if the zip.so was included.

Here's another way.

Here's the one you want. This is lazy [\s\S]*?

The first item: [\s\S]*?(?:location="[^"]*")[\s\S]* Replace with: $1

For completeness, this gets the last one. This is greedy [\s\S]*

There's only 1 difference between these two regular expressions and that is the ?

Those saying that you can't safely remove an item from a collection except through the Iterator aren't quite correct, you can do it safely using one of the concurrent collections such as ConcurrentHashMap.

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;

Here is another way to use SQL SELECT statement in VBA:

 sSQL = "SELECT Variable FROM GroupTable WHERE VariableCode = '" & Me.comboBox & "'" 
 Set rs = CurrentDb.OpenRecordset(sSQL)

 dbValue = rs!Variable
 MsgBox dbValue, vbOKOnly, "RS VALUE"
resultsetError:

Use negative lookaround: (?!pattern)

Positive lookarounds can be used to assert that a pattern matches. Negative lookarounds is the opposite: it's used to assert that a pattern DOES NOT match. Some flavor supports assertions; some puts limitations on lookbehind, etc.

ou are able to create local variables once you call the render function on a partial, therefore if you want to customize a partial you can for example render the partial _form.html.erb by:

<%= render 'form', button_label: "Create New Event", url: new_event_url %>
<%= render 'form', button_label: "Update Event", url: edit_event_url %>

this way you can access in the partial to the label for the button and the URL, those are different if you try to create or update a record. finally, for accessing to this local variables you have to put in your code local_assigns[:button_label] (local_assigns[:name_of_your_variable])

<%=form_for(@event, url: local_assigns[:url]) do |f|  %>
<%= render 'shared/error_messages_events' %>
<%= f.label :title ,"Title"%>
  <%= f.text_field :title, class: 'form-control'%>
  <%=f.label :date, "Date"%>
  <%=f.date_field :date, class: 'form-control'  %>
  <%=f.label :description, "Description"%>
  <%=f.text_area :description, class: 'form-control'  %>
  <%= f.submit local_assigns[:button_label], class:"btn btn-primary"%>
<%end%>

Have your Activity implement OnFocusChangeListener() if you want a factorized use of this interface, example:

public class Shops extends AppCompatActivity implements View.OnFocusChangeListener{

In your OnCreate you can add a listener for example:

editTextResearch.setOnFocusChangeListener(this);
editTextMyWords.setOnFocusChangeListener(this);
editTextPhone.setOnFocusChangeListener(this);

then android studio will prompt you to add the method from the interface, accept it... it will be like:

@Override
public void onFocusChange(View v, boolean hasFocus) {
// todo your code here...
}

and as you've got a factorized code, you'll just have to do that:

@Override
public void onFocusChange(View v, boolean hasFocus) {
   if (hasFocus) {
        editTextResearch.setText("");
        editTextMyWords.setText("");
        editTextPhone.setText("");
    }
    if (!hasFocus){
        editTextResearch.setText("BlaBlaBla");
        editTextMyWords.setText(" One Two Tree!");
        editTextPhone.setText("\"your phone here:\"");
    }
}

anything you code in the !hasFocus is for the behavior of the item that loses focus, that should do the trick! But beware that in such state, the change of focus might overwrite the user's entries!

I know this is old, but just to make it clear, there is an explanation of each in the official android documentation:

from http://developer.android.com/tools/projects/index.html

assets/

This is empty. You can use it to store raw asset files. Files that you save here are compiled into an .apk file as-is, and the original filename is preserved. You can navigate this directory in the same way as a typical file system using URIs and read files as a stream of bytes using the AssetManager. For example, this is a good location for textures and game data.

res/raw/

For arbitrary raw asset files. Saving asset files here instead of in the assets/ directory only differs in the way that you access them. These files are processed by aapt and must be referenced from the application using a resource identifier in the R class. For example, this is a good place for media, such as MP3 or Ogg files.

If ESLint is running in the terminal but not inside VSCode, it is probably because the extension is unable to detect both the local and the global node_modules folders.

To verify, press Ctrl+Shift+U in VSCode to open the Output panel after opening a JavaScript file with a known eslint issue. If it shows Failed to load the ESLint library for the document {documentName}.js -or- if the Problems tab shows an error or a warning that refers to eslint, then VSCode is having a problem trying to detect the path.

If yes, then set it manually by configuring the eslint.nodePath in the VSCode settings (settings.json). Give it the full path (for example, like "eslint.nodePath": "C:\\Program Files\\nodejs",) -- using environment variables is currently not supported.
This option has been documented at the ESLint extension page.

The problem may lie in you don't have enabled openssl extention in your php.ini file

go to your php.ini file end remove ; in line where extension=openssl is

Of course in question code there is a part of code responsible for checking whether extension is loaded or not but maybe some uncautious forget about it

I submit that it is better to leave your data stacked as it is:

df = pandas.DataFrame(data, columns=['R_Number', 'C_Number', 'Avg', 'Std'])

# Possibly also this if these can always be the indexes:
# df = df.set_index(['R_Number', 'C_Number'])

Then it's a bit more intuitive to say

df.set_index(['R_Number', 'C_Number']).Avg.unstack(level=1)

This way it is implicit that you're seeking to reshape the averages, or the standard deviations. Whereas, just using pivot, it's purely based on column convention as to what semantic entity it is that you are reshaping.

Not related to variables, your example will also be solved by MOD:

=Mod(VLOOKUP(A1, B:B, 1, 0);10)

There is no such thing as :touch in the W3C specifications, http://www.w3.org/TR/CSS2/selector.html#pseudo-class-selectors

:active should work, I would think.

Order on the :active/:hover pseudo class is important for it to function correctly.

Here is a quote from that above link

Interactive user agents sometimes change the rendering in response to user actions. CSS provides three pseudo-classes for common cases:

• The :hover pseudo-class applies while the user designates an element (with some pointing device), but does not activate it. For example, a visual user agent could apply this pseudo-class when the cursor (mouse pointer) hovers over a box generated by the element. User agents not supporting interactive media do not have to support this pseudo-class. Some conforming user agents supporting interactive media may not be able to support this pseudo-class (e.g., a pen device).
• The :active pseudo-class applies while an element is being activated by the user. For example, between the times the user presses the mouse button and releases it.
• The :focus pseudo-class applies while an element has the focus (accepts keyboard events or other forms of text input).

If you specify CSS attributes for your body element it should apply to anything within <body></body> so long as you don't override them later in the stylesheet.

I know notepad++ has a feature that lets you select blocks of text independent of line/column by holding control + alt + drag. So you can select just about any block of text you want.

Object.defineProperty() is a global function..Its not available inside the function which declares the object otherwise.You'll have to use it statically...

Let's try.. It is working for me..

svn add * --force

Vincent Povirk's answer won't work completely;

import zipfile
archive = zipfile.ZipFile('images.zip', 'r')
imgfile = archive.open('img_01.png')
...

You have to change it in:

import zipfile
archive = zipfile.ZipFile('images.zip', 'r')
imgdata = archive.read('img_01.png')
...

For details read the ZipFile docs here.

You can find the headers option in the Network tab in Developer's console in Chrome:

1. In Chrome press F12 to open Developer's console.
2. Select the Network tab. This tab gives you the information about the requests fired from the browser.
3. Select a request by clicking on the request name. There you can find the Header information for that request along with some other information like Preview, Response and Timing.

Also, in my version of Chrome (50.0.2661.102), it gives an extension named LIVE HTTP Headers which gives information about the request headers for all the HTTP requests.

Used the Accepted Answer to do a check for IE and convert the dataURI to UInt8Array; an accepted form by PDFJS

        Ext.isIE ? pdfAsDataUri = me.convertDataURIToBinary(pdfAsDataUri): '';_x000D_
_x000D_
        convertDataURIToBinary: function(dataURI) {_x000D_
          var BASE64_MARKER = ';base64,',_x000D_
            base64Index = dataURI.indexOf(BASE64_MARKER) + BASE64_MARKER.length,_x000D_
            base64 = dataURI.substring(base64Index),_x000D_
            raw = window.atob(base64),_x000D_
            rawLength = raw.length,_x000D_
            array = new Uint8Array(new ArrayBuffer(rawLength));_x000D_
_x000D_
          for (var i = 0; i < rawLength; i++) {_x000D_
            array[i] = raw.charCodeAt(i);_x000D_
          }_x000D_
          return array;_x000D_
        },

That error is a parse error. The parser is throwing it while going through the code, trying to understand it. No code is being executed yet in the parsing stage. Because of that it hasn't yet executed the error_reporting line, therefore the error reporting settings aren't changed yet.

You cannot change error reporting settings (or really, do anything) in a file with syntax errors.

Try:

strng = ""
for i in range(97,123):
    strng = strng + chr(i)
print(strng)

If you are trying to

1. Use multiple delimiters
2. Filter any empty strings
3. Trim leading/trailing spaces

following should work:

string str = "Tom Cruise, Scott, ,Bob | at";
IEnumerable<string> names = str
                            .Split(new char[]{',', '|'})
                            .Where(x=>x!=null && x.Trim().Length > 0)
                            .Select(x=>x.Trim());

Output

• Tom
• Cruise
• Scott
• Bob
• at

Now you can obviously reverse the order as others suggested.

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

For example:

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

Edited to reflect update to question

$(document).ready(function() {
    $(".res a").click(function() {
        alert($(this).attr("href"));
    });
});

Try this Toggle Buttons

test_activity.xml

<ToggleButton 
android:id="@+id/togglebutton" 
android:layout_width="100px" 
android:layout_height="50px" 
android:layout_centerVertical="true" 
android:layout_centerHorizontal="true"
android:onClick="toggleclick"/>

Test.java

public class Test extends Activity {

private ToggleButton togglebutton;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    togglebutton = (ToggleButton) findViewById(R.id.togglebutton);
}

public void toggleclick(View v){
    if(togglebutton.isChecked())
        Toast.makeText(TestActivity.this, "ON", Toast.LENGTH_SHORT).show();
    else
        Toast.makeText(TestActivity.this, "OFF", Toast.LENGTH_SHORT).show();
    }
}

In memory usage and speed.

When you call jsonstr = json.dumps(mydata) it first creates a full copy of your data in memory and only then you file.write(jsonstr) it to disk. So this is a faster method but can be a problem if you have a big piece of data to save.

When you call json.dump(mydata, file) -- without 's', new memory is not used, as the data is dumped by chunks. But the whole process is about 2 times slower.

Source: I checked the source code of json.dump() and json.dumps() and also tested both the variants measuring the time with time.time() and watching the memory usage in htop.

Add a jQuery function,

(function($){
    $.fn.regex = function(pattern, fn, fn_a){
        var fn = fn || $.fn.text;
        return this.filter(function() {
            return pattern.test(fn.apply($(this), fn_a));
        });
    };
})(jQuery);

Then,

$('span').regex(/Sent/)

will select all span elements with text matches /Sent/.

$('span').regex(/tooltip.year/, $.fn.attr, ['class'])

will select all span elements with their classes match /tooltip.year/.

BTW you can pass the error message directly to sys.exit:

if len(sys.argv) < 2:
    sys.exit('Usage: %s database-name' % sys.argv[0])

if not os.path.exists(sys.argv[1]):
    sys.exit('ERROR: Database %s was not found!' % sys.argv[1])

Spring is a good alternative to Enterprise JavaBeans (EJB) technology. It also has web framework and web services framework component.

Never, never, never say

if something == True:

Never. It's crazy, since you're redundantly repeating what is redundantly specified as the redundant condition rule for an if-statement.

Worse, still, never, never, never say

if something == False:

You have not. Feel free to use it.

Finally, doing a == None is inefficient. Do a is None. None is a special singleton object, there can only be one. Just check to see if you have that object.

I have experienced the same situation I did the below as this much easier. By passing commit-Id you can reach to the particular commit you want to go:

git reset --hard {commit-id}

As you want to remove your last commit so you need to pass the commit-Id where you need to move your pointer:

git reset --hard db0c078d5286b837532ff5e276dcf91885df2296

Docstrings are only useful within interactive environments, e.g. the Python shell. When documenting objects that are not going to be used interactively (e.g. internal objects, framework callbacks), you might as well use regular comments. Here’s a style I use for hanging indented comments off items, each on their own line, so you know that the comment is applying to:

def Recomputate \
  (
    TheRotaryGyrator,
      # the rotary gyrator to operate on
    Computrons,
      # the computrons to perform the recomputation with
    Forthwith,
      # whether to recomputate forthwith or at one's leisure
  ) :
  # recomputates the specified rotary gyrator with
  # the desired computrons.
  ...
#end Recomputate

You can’t do this sort of thing with docstrings.

public enum EnumRole {

ROLE_ANONYMOUS_USER_ROLE ("anonymous user role"),
ROLE_INTERNAL ("internal role");

private String roleName;

public String getRoleName() {
    return roleName;
}

EnumRole(String roleName) {
    this.roleName = roleName;
}

public static final EnumRole getByValue(String value){
    return Arrays.stream(EnumRole.values()).filter(enumRole -> enumRole.roleName.equals(value)).findFirst().orElse(ROLE_ANONYMOUS_USER_ROLE);
}

public static void main(String[] args) {
    System.out.println(getByValue("internal role").roleName);
}

}

From the accepted answer, it looks like your desired behaviour is to turn

If that's right, then I think something like

import csv

with open("test.dat", "rb") as infile, open("test.csv", "wb") as outfile:
    reader = csv.reader(infile)
    writer = csv.writer(outfile, quoting=False)
    for i, line in enumerate(reader):
        if i < 4: continue
        date = line[0].split()
        day = date[0].split('-')
        time = date[1].split(':')
        newline = day + time + line[1:]
        writer.writerow(newline)

would be a little simpler than the reps stuff.

I also got this error (within the Eclipse-based STM32CubeIDE on Windows).

After double-clicking on the "multiple target patterns" error it showed a path to a .ld file. It turns out to be another "illegal character" problem. The offending character was the (wait for it): =

The GNU make manual doesn't explicitly document this.

If for example, it is an Ubuntu, after installing the packages:

$sudo apt install golang -y

Just add the following lines to ~/.bashrc (Of your user)

You need to try one of the following:

1. GridBagLayout
2. MigLayout
3. SpringLayout

They offer many more features and will be easier to get what you are looking for.

Cloning the objects before adding them. For example, instead of newList.addAll(oldList);

for(Person p : oldList) {
    newList.add(p.clone());
}

Assuming clone is correctly overriden inPerson.

As others have mentioned the underlying dict is unordered. However there are OrderedDict objects in python. ( They're built in in recent pythons, or you can use this: http://code.activestate.com/recipes/576693/ ).

I believe that newer pythons json implementations correctly handle the built in OrderedDicts, but I'm not sure (and I don't have easy access to test).

Old pythons simplejson implementations dont handle the OrderedDict objects nicely .. and convert them to regular dicts before outputting them.. but you can overcome this by doing the following:

class OrderedJsonEncoder( simplejson.JSONEncoder ):
   def encode(self,o):
      if isinstance(o,OrderedDict.OrderedDict):
         return "{" + ",".join( [ self.encode(k)+":"+self.encode(v) for (k,v) in o.iteritems() ] ) + "}"
      else:
         return simplejson.JSONEncoder.encode(self, o)

now using this we get:

>>> import OrderedDict
>>> unordered={"id":123,"name":"a_name","timezone":"tz"}
>>> ordered = OrderedDict.OrderedDict( [("id",123), ("name","a_name"), ("timezone","tz")] )
>>> e = OrderedJsonEncoder()
>>> print e.encode( unordered )
{"timezone": "tz", "id": 123, "name": "a_name"}
>>> print e.encode( ordered )
{"id":123,"name":"a_name","timezone":"tz"}

Which is pretty much as desired.

Another alternative would be to specialise the encoder to directly use your row class, and then you'd not need any intermediate dict or UnorderedDict.

I have to display files of computer code. If special characters are inside the file like less than or greater than, a simple "include" will not display them. Try:

$file = 'code.ino';
$orig = file_get_contents($file);
$a = htmlentities($orig);

echo '<code>';
echo '<pre>';

echo $a;

echo '</pre>';
echo '</code>';

I used this 457-55-5462 as testing SSN and it worked for me. I used it at paypal sandbox account. Hope it helps somebody

I needed an elegant solution for the busybox (router), all xargs or array solutions were useless to me - no such command available there. find and mtime is not the proper answer as we are talking about 10 items and not necessarily 10 days. Espo's answer was the shortest and cleanest and likely the most unversal one.

Error with spaces and when no files are to be deleted are both simply solved the standard way:

rm "$(ls -td *.tar | awk 'NR>7')" 2>&-

Bit more educational version: We can do it all if we use awk differently. Normally, I use this method to pass (return) variables from the awk to the sh. As we read all the time that can not be done, I beg to differ: here is the method.

Example for .tar files with no problem regarding the spaces in the filename. To test, replace "rm" with the "ls".

eval $(ls -td *.tar | awk 'NR>7 { print "rm \"" $0 "\""}')

Explanation:

ls -td *.tar lists all .tar files sorted by the time. To apply to all the files in the current folder, remove the "d *.tar" part

awk 'NR>7... skips the first 7 lines

print "rm \"" $0 "\"" constructs a line: rm "file name"

eval executes it

Since we are using rm, I would not use the above command in a script! Wiser usage is:

(cd /FolderToDeleteWithin && eval $(ls -td *.tar | awk 'NR>7 { print "rm \"" $0 "\""}'))

In the case of using ls -t command will not do any harm on such silly examples as: touch 'foo " bar' and touch 'hello * world'. Not that we ever create files with such names in real life!

Sidenote. If we wanted to pass a variable to the sh this way, we would simply modify the print (simple form, no spaces tolerated):

print "VarName="$1

to set the variable VarName to the value of $1. Multiple variables can be created in one go. This VarName becomes a normal sh variable and can be normally used in a script or shell afterwards. So, to create variables with awk and give them back to the shell:

eval $(ls -td *.tar | awk 'NR>7 { print "VarName=\""$1"\""  }'); echo "$VarName"

If you're in VB 9 (VS2008), a predicate can be a complex function:

Dim list As New List(Of Integer)(New Integer() {1, 2, 3})
Dim newList = list.FindAll(AddressOf GreaterThanTwo)
...
Function GreaterThanTwo(ByVal item As Integer) As Boolean
    'do some work'
    Return item > 2
End Function

Or you can write your predicate as a lambda, as long as it's only one expression:

Dim list As New List(Of Integer)(New Integer() {1, 2, 3})
Dim newList = list.FindAll(Function(item) item > 2)

If you want to preserve your commit (maybe you already spent some time writing a detailed commit message and don't want to lose it), and you only want to remove the file from the commit, but not from the repository entirely:

git checkout origin/<remote-branch> <filename>
git commit --amend

version name : BuildConfig.VERSION_NAME version code : BuildConfig.VERSION_CODE

Your solution makes use of an extension to GROUP BY clause that permits to group by some fields (in this case, just post_author):

GROUP BY wp_posts.post_author

and select nonaggregated columns:

SELECT wp_posts.*

that are not listed in the group by clause, or that are not used in an aggregate function (MIN, MAX, COUNT, etc.).

Correct use of extension to GROUP BY clause

This is useful when all values of non-aggregated columns are equal for every row.

For example, suppose you have a table GardensFlowers (name of the garden, flower that grows in the garden):

INSERT INTO GardensFlowers VALUES
('Central Park',       'Magnolia'),
('Hyde Park',          'Tulip'),
('Gardens By The Bay', 'Peony'),
('Gardens By The Bay', 'Cherry Blossom');

and you want to extract all the flowers that grows in a garden, where multiple flowers grow. Then you have to use a subquery, for example you could use this:

SELECT GardensFlowers.*
FROM   GardensFlowers
WHERE  name IN (SELECT   name
                FROM     GardensFlowers
                GROUP BY name
                HAVING   COUNT(DISTINCT flower)>1);

If you need to extract all the flowers that are the only flowers in the garder instead, you could just change the HAVING condition to HAVING COUNT(DISTINCT flower)=1, but MySql also allows you to use this:

SELECT   GardensFlowers.*
FROM     GardensFlowers
GROUP BY name
HAVING   COUNT(DISTINCT flower)=1;

no subquery, not standard SQL, but simpler.

Incorrect use of extension to GROUP BY clause

But what happens if you SELECT non-aggregated columns that are non equal for every row? Which is the value that MySql chooses for that column?

It looks like MySql always chooses the FIRST value it encounters.

To make sure that the first value it encounters is exactly the value you want, you need to apply a GROUP BY to an ordered query, hence the need to use a subquery. You can't do it otherwise.

Given the assumption that MySql always chooses the first row it encounters, you are correcly sorting the rows before the GROUP BY. But unfortunately, if you read the documentation carefully, you'll notice that this assumption is not true.

When selecting non-aggregated columns that are not always the same, MySql is free to choose any value, so the resulting value that it actually shows is indeterminate.

I see that this trick to get the first value of a non-aggregated column is used a lot, and it usually/almost always works, I use it as well sometimes (at my own risk). But since it's not documented, you can't rely on this behaviour.

This link (thanks ypercube!) GROUP BY trick has been optimized away shows a situation in which the same query returns different results between MySql and MariaDB, probably because of a different optimization engine.

So, if this trick works, it's just a matter of luck.

The accepted answer on the other question looks wrong to me:

HAVING wp_posts.post_date = MAX(wp_posts.post_date)

wp_posts.post_date is a non-aggregated column, and its value will be officially undetermined, but it will likely be the first post_date encountered. But since the GROUP BY trick is applied to an unordered table, it is not sure which is the first post_date encountered.

It will probably returns posts that are the only posts of a single author, but even this is not always certain.

A possible solution

I think that this could be a possible solution:

SELECT wp_posts.*
FROM   wp_posts
WHERE  id IN (
  SELECT max(id)
  FROM wp_posts
  WHERE (post_author, post_date) = (
    SELECT   post_author, max(post_date)
    FROM     wp_posts
    WHERE    wp_posts.post_status='publish'
             AND wp_posts.post_type='post'
    GROUP BY post_author
  ) AND wp_posts.post_status='publish'
    AND wp_posts.post_type='post'
  GROUP BY post_author
)

On the inner query I'm returning the maximum post date for every author. I'm then taking into consideration the fact that the same author could theorically have two posts at the same time, so I'm getting only the maximum ID. And then I'm returning all rows that have those maximum IDs. It could be made faster using joins instead of IN clause.

(If you're sure that ID is only increasing, and if ID1 > ID2 also means that post_date1 > post_date2, then the query could be made much more simple, but I'm not sure if this is the case).

This example will help you to understand the React Life Cycle Hooks.

You can setState in getDerivedStateFromProps method i.e. static and trigger the method after props change in componentDidUpdate.

In componentDidUpdate you will get 3rd param which returns from getSnapshotBeforeUpdate.

Keras like model summary using torchsummary:

from torchsummary import summary
summary(model, input_size=(3, 224, 224))

I have quickly made a function that can achieve this, it may not be the best way to do this but it simply works and should be cross browser, please also know that i am NOT a expert in JavaScript so any tips are great :)

Pure Javascript Create Element Solution

function createElement(){
    var element  = document.createElement(arguments[0]),
        text     = arguments[1],
        attr     = arguments[2],
        append   = arguments[3],
        appendTo = arguments[4];

    for(var key = 0; key < Object.keys(attr).length ; key++){
        var name = Object.keys(attr)[key],
             value = attr[name],
             tempAttr = document.createAttribute(name);
             tempAttr.value = value;
        element.setAttributeNode(tempAttr)
    }
    
    if(append){
        for(var _key = 0; _key < append.length; _key++) {
            element.appendChild(append[_key]);
        }
    }

    if(text) element.appendChild(document.createTextNode(text));

    if(appendTo){
        var target = appendTo === 'body' ? document.body : document.getElementById(appendTo);
        target.appendChild(element)
    }       

    return element;
}

lets see how we make this

<select name="drop1" id="Select1">
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

here's how it works

    var options = [
        createElement('option', 'Volvo', {value: 'volvo'}),
        createElement('option', 'Saab', {value: 'saab'}),
        createElement('option', 'Mercedes', {value: 'mercedes'}),
        createElement('option', 'Audi', {value: 'audi'})
    ];


    createElement('select', null, // 'select' = name of element to create, null = no text to insert
        {id: 'Select1', name: 'drop1'}, // Attributes to attach
        [options[0], options[1], options[2], options[3]], // append all 4 elements
        'body' // append final element to body - this also takes a element by id without the #
    );

this is the params

createElement('tagName', 'Text to Insert', {any: 'attribute', here: 'like', id: 'mainContainer'}, [elements, to, append, to, this, element], 'body || container = where to append this element');

This function would suit if you have to append many element, if there is any way to improve this answer please let me know.

edit:

Here is a working demo

JSFiddle Demo

This can be highly customized to suit your project!

Based on Laravel docs for raw queries I was able to get count for a select field to work with this code in the product model.

public function scopeShowProductCount($query)
{
    $query->select(DB::raw('DISTINCT pid, COUNT(*) AS count_pid'))
          ->groupBy('pid')
          ->orderBy('count_pid', 'desc');
}

This facade worked to get the same result in the controller:

$products = DB::table('products')->select(DB::raw('DISTINCT pid, COUNT(*) AS count_pid'))->groupBy('pid')->orderBy('count_pid', 'desc')->get();

The resulting dump for both queries was as follows:

#attributes: array:2 [
  "pid" => "1271"
  "count_pid" => 19
],
#attributes: array:2 [
  "pid" => "1273"
  "count_pid" => 12
],
#attributes: array:2 [
  "pid" => "1275"
  "count_pid" => 7
]

If you transferred these files through disk or other means, it is likely they were not saved properly.

The RSACryptoServiceProvider(CspParameters) constructor creates a keypair which is stored in the keystore on the local machine. If you already have a keypair with the specified name, it uses the existing keypair.

It sounds as if you are not interested in having the key stored on the machine.

So use the RSACryptoServiceProvider(Int32) constructor:

public static void AssignNewKey(){
    RSA rsa = new RSACryptoServiceProvider(2048); // Generate a new 2048 bit RSA key

    string publicPrivateKeyXML = rsa.ToXmlString(true);
    string publicOnlyKeyXML = rsa.ToXmlString(false);
    // do stuff with keys...
}

EDIT:

Alternatively try setting the PersistKeyInCsp to false:

public static void AssignNewKey(){
    const int PROVIDER_RSA_FULL = 1;
    const string CONTAINER_NAME = "KeyContainer";
    CspParameters cspParams;
    cspParams = new CspParameters(PROVIDER_RSA_FULL);
    cspParams.KeyContainerName = CONTAINER_NAME;
    cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
    cspParams.ProviderName = "Microsoft Strong Cryptographic Provider";
    rsa = new RSACryptoServiceProvider(cspParams);

    rsa.PersistKeyInCsp = false;

    string publicPrivateKeyXML = rsa.ToXmlString(true);
    string publicOnlyKeyXML = rsa.ToXmlString(false);
    // do stuff with keys...
}

Here's a neat way I did it:

table tr {
    border-bottom: 4px solid;
}

That will add 4px of vertical spacing between each row. And if you wanted to not get that border on the last child:

table tr:last-child {
    border-bottom: 0;
}

Reminder that CSS3 pseudo-selectors will only work in IE 8 and below with selectivizr.

Casting the NSTimeInterval directly to a long overflowed for me, so instead I had to cast to a long long.

long long milliseconds = (long long)([[NSDate date] timeIntervalSince1970] * 1000.0);

The result is a 13 digit timestamp as in Unix.

try changing this:

$(this).find(':checkbox').attr('checked', true ); 

to this:

$(this).find(':checkbox').attr('checked', 'checked'); 

Not 100% sure if that will do it, but I seem to recall having a similar problem. Good luck!

Not perfect but I think it must be safest. Add nl2br:

$skuList = explode('<br />', nl2br($_POST['skuList']));

Lot's of great answer. I just want to add a small note about decoupling the stream.

cin.tie(NULL);

I have faced an issue while decoupling the stream with CodeChef platform. When I submitted my code, the platform response was "Wrong Answer" but after tying the stream and testing the submission. It worked.

So, If anyone wants to untie the stream, the output stream must be flushed.

Edit: I am not familiar with all the platform but this is what I have experienced.
