Even though this solution is done with jQuery I though it may be useful for anyone doing columns to fit the screen size.

For columns starting at the top of the page, this solution is the simplest.

body,html{
  height:100%;
}

div#right{
  height:100%
}

For columns that are not starting at the top of the page (for example: if they are starting below the header).

<script>
     $(document).ready(function () {
        var column_height = $("body").height();
        column_height = column_height - 100; // 100 is the header height
        column_height = column_height + "px";
        $("#column").css("height",column_height);
    });
</script>

First method applies the body height to it and the columns as well, which means that is starting_pixels + height100%.

The second method gets the height of page shown to the user by getting the height of the body and then subtracts the header size to know how much height is left to display the column.

Iv'e noticed this recently with all new macs here at my office. Atom will be installed via an image for the developers but we found the Atom is never in the Application folder.

When doing a ls on the /usr/local/bin folder the path for atom will show something like "/private/var/folders/cs" . To resolve this, we just located atom.app and copied it into the application folder, then ran the system link commands provided by nwinkler which resoled the issue. Developers can now open atom from the command line with "atom" or open the current projects from their working director with "atom ."

Looking for the possibility to put a powershell script into a batch file, I found this thread. The idea of walid2mi did not worked 100% for my script. But via a temporary file, containing the script it worked out. Here is the skeleton of the batch file:

;@echo off
;setlocal ENABLEEXTENSIONS
;rem make from X.bat a X.ps1 by removing all lines starting with ';' 
;Findstr -rbv "^[;]" %0 > %~dpn0.ps1 
;powershell -ExecutionPolicy Unrestricted -File %~dpn0.ps1 %*
;del %~dpn0.ps1
;endlocal
;goto :EOF
;rem Here start your power shell script.
param(
    ,[switch]$help
)

I'm not sure why these answer are so complex, try:

dynamic settings = new
            {
                Filename = "temp.txt",
                Size = 10
            };

string fileName = settings.Filename;

var fileNameExists = fileName != null;

I don't like the accepted answer or @fivetwentysix's comment regarding how to solve this. It gets at one method for doing this, but doesn't give the full solution to using toArray. You need to use toArray and give it an argument that's an array of the correct type and size so that you don't end up with an Object array. While an object array will work, I don't think it's best practice in a strongly typed language.

String[] array = arrayList.toArray(new String[arrayList.size()]);
JComboBox comboBox = new JComboBox(array);

Alternatively, you can also maintain strong typing by just using a for loop.

String[] array = new String[arrayList.size()];
for(int i = 0; i < array.length; i++) {
    array[i] = arrayList.get(i);
}
JComboBox comboBox = new JComboBox(array);

A file object is an instance of Blob but a blob object is not an instance of File

new File([], 'foo.txt').constructor.name === 'File' //true
new File([], 'foo.txt') instanceof File // true
new File([], 'foo.txt') instanceof Blob // true

new Blob([]).constructor.name === 'Blob' //true
new Blob([]) instanceof Blob //true
new Blob([]) instanceof File // false

new File([], 'foo.txt').constructor.name === new Blob([]).constructor.name //false

If you must convert a file object to a blob object, you can create a new Blob object using the array buffer of the file. See the example below.

let file = new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'});
//or let file = document.querySelector('input[type=file]').files[0];
let reader = new FileReader();
reader.onload = function(e) {
    let blob = new Blob([new Uint8Array(e.target.result)], {type: file.type });
    console.log(blob);
};
reader.readAsArrayBuffer(file);

As pointed by @bgh you can also use the arrayBuffer method of the File object. See the example below.

let file = new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'});
//or let file = document.querySelector('input[type=file]').files[0];

file.arrayBuffer().then((arrayBuffer) => {
    let blob = new Blob([new Uint8Array(arrayBuffer)], {type: file.type });
    console.log(blob);
});

If your environment supports async/await you can use a one-liner like below

let fileToBlob = async (file) => new Blob([new Uint8Array(await file.arrayBuffer())], {type: file.type });
console.log(await fileToBlob(new File(['hello', ' ', 'world'], 'hello_world.txt', {type: 'text/plain'})));

This is ok but do not split the updateResources into different versions, just use the solution below (kotlin). Key is in "Configuration(context.resources.configuration)" it makes deep copy.

100% solution for API 21+. I have not tested for lower ones, but should work.

private fun updateResources(context: Context, language: String): Context {
    return Configuration(context.resources.configuration).run {
        Locale.setDefault(Locale(language).also { locale ->
            setLocale(locale)
        }).let {
            context.createConfigurationContext(this)
        }
    }
}

The best methods are already given but why not look at a couple of other methods for fun? Warning: these are more expensive methods but do serve in other circumstances.

The expensive regex method and the css attribute selector with starts with ^ operator

Option Explicit

Public Sub test()

    Debug.Print StartWithSubString("ab", "abc,d")

End Sub

Regex:

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft VBScript Regular Expressions
    Dim re As VBScript_RegExp_55.RegExp
    Set re = New VBScript_RegExp_55.RegExp

    re.Pattern = "^" & substring

    StartWithSubString = re.test(testString)

End Function

Css attribute selector with starts with operator

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft HTML Object Library
    Dim html As MSHTML.HTMLDocument
    Set html = New MSHTML.HTMLDocument

    html.body.innerHTML = "<div test=""" & testString & """></div>"

    StartWithSubString = html.querySelectorAll("[test^=" & substring & "]").Length > 0

End Function

So the length is between 10 16-bit chars, and 40 hex digits.

In any case decide the format you are going to store, and make the field a fixed size based on that format. That way you won't have any wasted space.

I understand the question as this: you want to completely replace the contents of one file (or a selection) from upstream. You don't want to affect the index directly (so you would go through add + commit as usual).

Simply do

git checkout remote/branch -- a/file b/another/file

If you want to do this for extensive subtrees and instead wish to affect the index directly use

git read-tree remote/branch:subdir/

You can then (optionally) update your working copy by doing

git checkout-index -u --force

Can't you style the forms themselves? Then, style the divs accordingly.

form
{
    /* styles */
}

You can always overrule inherited styles by making it important:

form
{
    /* styles */ !important
}

@folex answer is right.

But it will fail if the tableView has more than one section displayed at a time.

-(void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
   if([indexPath isEqual:((NSIndexPath*)[[tableView indexPathsForVisibleRows] lastObject])]){
    //end of loading

 }
}

var list = new List<string>();
var queryable = list.AsQueryable();

Add a reference to: System.Linq

Hope this will help you

Cast(columnName as Numeric(10,2)) 
        or

Cast(@s as decimal(10,2))

I am not getting why you want to cast to varchar?.If you cast to varchar again convert back to decimail for two decimal points

Just here to show my implementation for @herman solution

ZoneId americaLaPazZone = ZoneId.of("UTC-04:00");

static Date firstDateOfMonth(Date date) {
  LocalDate localDate = convertToLocalDateWithTimezone(date);
  YearMonth baseMonth = YearMonth.from(localDate);
  LocalDateTime initialDate = baseMonth.atDay(firstDayOfMonth).atStartOfDay();
  return Date.from(initialDate.atZone(americaLaPazZone).toInstant());
}

static Date lastDateOfMonth(Date date) {
  LocalDate localDate = convertToLocalDateWithTimezone(date);
  YearMonth baseMonth = YearMonth.from(localDate);
  LocalDateTime lastDate = baseMonth.atEndOfMonth().atTime(23, 59, 59);
  return Date.from(lastDate.atZone(americaLaPazZone).toInstant());
}

static LocalDate convertToLocalDateWithTimezone(Date date) {
  return LocalDateTime.from(date.toInstant().atZone(americaLaPazZone)).toLocalDate();
}

You can use * for import all jars into a folder when adding in conf/spark-defaults.conf .

spark.driver.extraClassPath /fullpath/*
spark.executor.extraClassPath /fullpath/*

Just in case you want the binary representation and you're still drunk from last night's party:

private static string ByteToString(int value)
{
    StringBuilder builder = new StringBuilder(sizeof(byte) * 8);
    BitArray[] bitArrays = BitConverter.GetBytes(value).Reverse().Select(b => new BitArray(new []{b})).ToArray();
    foreach (bool bit in bitArrays.SelectMany(bitArray => bitArray.Cast<bool>().Reverse()))
    {
        builder.Append(bit ? '1' : '0');
    }
    return builder.ToString();
}

Note: Something about not handling endianness very nicely...

If you don't mind sacrificing a bit of memory for speed, you can use below to generate an array with pre-calculated string values:

static void OutputIntegerStringRepresentations()
{
    Console.WriteLine("private static string[] integerAsDecimal = new [] {");
    for (int i = int.MinValue; i < int.MaxValue; i++)
    {
        Console.WriteLine("\t\"{0}\",", i);
    }
    Console.WriteLine("\t\"{0}\"", int.MaxValue);
    Console.WriteLine("}");
}

In React 16.8+, using functional components, you would do

import React from 'react';
import { Button, Linking } from 'react-native';

const ExternalLinkBtn = (props) => {
  return <Button
            title={props.title}
            onPress={() => {
                Linking.openURL(props.url)
                .catch(err => {
                    console.error("Failed opening page because: ", err)
                    alert('Failed to open page')
                })}}
          />
}

export default function exampleUse() {
  return (
    <View>
      <ExternalLinkBtn title="Example Link" url="https://example.com" />
    </View>
  )
}

The code below calculates the correct ISO 8601 week number. It matches PHP's date("W") for every week between 1/1/1970 and 1/1/2100.

/**
 * Get the ISO week date week number
 */
Date.prototype.getWeek = function () {
  // Create a copy of this date object
  var target = new Date(this.valueOf());

  // ISO week date weeks start on Monday, so correct the day number
  var dayNr = (this.getDay() + 6) % 7;

  // ISO 8601 states that week 1 is the week with the first Thursday of that year
  // Set the target date to the Thursday in the target week
  target.setDate(target.getDate() - dayNr + 3);

  // Store the millisecond value of the target date
  var firstThursday = target.valueOf();

  // Set the target to the first Thursday of the year
  // First, set the target to January 1st
  target.setMonth(0, 1);

  // Not a Thursday? Correct the date to the next Thursday
  if (target.getDay() !== 4) {
    target.setMonth(0, 1 + ((4 - target.getDay()) + 7) % 7);
  }

  // The week number is the number of weeks between the first Thursday of the year
  // and the Thursday in the target week (604800000 = 7 * 24 * 3600 * 1000)
  return 1 + Math.ceil((firstThursday - target) / 604800000);
}

Source: Taco van den Broek

If you're not into extending prototypes, then here's a function:

function getWeek(date) {
  if (!(date instanceof Date)) date = new Date();

  // ISO week date weeks start on Monday, so correct the day number
  var nDay = (date.getDay() + 6) % 7;

  // ISO 8601 states that week 1 is the week with the first Thursday of that year
  // Set the target date to the Thursday in the target week
  date.setDate(date.getDate() - nDay + 3);

  // Store the millisecond value of the target date
  var n1stThursday = date.valueOf();

  // Set the target to the first Thursday of the year
  // First, set the target to January 1st
  date.setMonth(0, 1);

  // Not a Thursday? Correct the date to the next Thursday
  if (date.getDay() !== 4) {
    date.setMonth(0, 1 + ((4 - date.getDay()) + 7) % 7);
  }

  // The week number is the number of weeks between the first Thursday of the year
  // and the Thursday in the target week (604800000 = 7 * 24 * 3600 * 1000)
  return 1 + Math.ceil((n1stThursday - date) / 604800000);
}

Sample usage:

getWeek(); // Returns 37 (or whatever the current week is)
getWeek(new Date('Jan 2, 2011')); // Returns 52
getWeek(new Date('Jan 1, 2016')); // Returns 53
getWeek(new Date('Jan 4, 2016')); // Returns 1

You might need to change your object to an array first. I dont know what export does, but I assume its expecting an array.

You can either use

get_object_vars()

Or if its a simple object, you can just typecast it.

$arr = (array) $Object;

To produce the output in your comment to your post, this will do it:

use strict;
use warnings;

my @other_array = (0,0,0,1,2,2,3,3,3,4);
my @array;
my %uniqs;

$uniqs{$_}++ for @other_array;

foreach (keys %uniqs) { $array[$_]=$uniqs{$_} }

print "array[$_] = $array[$_]\n" for (0..$#array);

Output:

   array[0] = 3
   array[1] = 1
   array[2] = 2
   array[3] = 3
   array[4] = 1

This is different than your stated algorithm of producing a parallel array with zero values, but it is a more Perly way of doing it...

If you must have a parallel array that is the same size as your first array with the elements initialized to 0, this statement will dynamically do it: @array=(0) x scalar(@other_array); but really, you don't need to do that.

Rebase doesn't happen in the background. "rebase in progress" means that you started a rebase, and the rebase got interrupted because of conflict. You have to resume the rebase (git rebase --continue) or abort it (git rebase --abort).

As the error message from git rebase --continue suggests, you asked git to apply a patch that results in an empty patch. Most likely, this means the patch was already applied and you want to drop it using git rebase --skip.

Add followning code in Application.onCreate then use it normal

    Picasso picasso = new Picasso.Builder(context)
            .downloader(new OkHttp3Downloader(this,Integer.MAX_VALUE))
            .build();
    picasso.setIndicatorsEnabled(true);
    picasso.setLoggingEnabled(true);
    Picasso.setSingletonInstance(picasso);

If you cache images first then do something like this in ProductImageDownloader.doBackground

final Callback callback = new Callback() {
            @Override
            public void onSuccess() {
                downLatch.countDown();
                updateProgress();
            }

            @Override
            public void onError() {
                errorCount++;
                downLatch.countDown();
                updateProgress();
            }
        };
        Picasso.with(context).load(Constants.imagesUrl+productModel.getGalleryImage())
                .memoryPolicy(MemoryPolicy.NO_CACHE).fetch(callback);
        Picasso.with(context).load(Constants.imagesUrl+productModel.getLeftImage())
                .memoryPolicy(MemoryPolicy.NO_CACHE).fetch(callback);
        Picasso.with(context).load(Constants.imagesUrl+productModel.getRightImage())
                .memoryPolicy(MemoryPolicy.NO_CACHE).fetch(callback);

        try {
            downLatch.await();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        if(errorCount == 0){
            products.remove(productModel);
            productModel.isDownloaded = true;
            productsDatasource.updateElseInsert(productModel);
        }else {
            //error occurred while downloading images for this product
            //ignore error for now
            // FIXME: 9/27/2017 handle error
            products.remove(productModel);

        }
        errorCount = 0;
        downLatch = new CountDownLatch(3);

        if(!products.isEmpty() /*&& testCount++ < 30*/){
            startDownloading(products.get(0));
        }else {
            //all products with images are downloaded
            publishProgress(100);
        }

and load your images like normal or with disk caching

    Picasso.with(this).load(Constants.imagesUrl+batterProduct.getGalleryImage())
        .networkPolicy(NetworkPolicy.OFFLINE)
        .placeholder(R.drawable.GalleryDefaultImage)
        .error(R.drawable.GalleryDefaultImage)
        .into(viewGallery);

Note:

Red color indicates that image is fetched from network.

Green color indicates that image is fetched from cache memory.

Blue color indicates that image is fetched from disk memory.

Before releasing the app delete or set it false picasso.setLoggingEnabled(true);, picasso.setIndicatorsEnabled(true); if not required. Thankx

It is really easy with Google Maps Android API v2

Just copy the example from Developer documentation

(of course you have to init your map first)

GoogleMap map;
 // ... get a map.
 // Add a thin red line from London to New York.
 Polyline line = map.addPolyline(new PolylineOptions()
     .add(new LatLng(51.5, -0.1), new LatLng(40.7, -74.0))
     .width(5)
     .color(Color.RED));

If you are using Eclipse you can move files to and from the SD Card through the Android Perspective (it is called DDMS in Eclipse). Just select the Emulator in the left part of the screen and then choose the File Explorer tab. Above the list with your files should be two symbols, one with an arrow pointing at a phone, clicking this will allow you to choose a file to move to phone memory.

You have to connect your client socket to the remote ServerSocket. Instead of

Socket clientSocket = new Socket("localhost", 5000);

do

Socket clientSocket = new Socket(serverName, 5000);

The client must connect to serverName which should match the name or IP of the box on which your ServerSocket was instantiated (the name must be reachable from the client machine). BTW: It's not the name that is important, it's all about IP addresses...

Make your toolbar like:

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/menuToolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="0dp"
android:background="@color/white"
android:contentInsetLeft="10dp"
android:contentInsetRight="10dp"
android:contentInsetStart="10dp"
android:minHeight="?attr/actionBarSize"
android:padding="0dp"
app:contentInsetLeft="10dp"
app:contentInsetRight="10dp"
app:contentInsetStart="10dp"></android.support.v7.widget.Toolbar>

You need to add

contentInset

attribute to add spacing

I managed to get the desired result, but with a slightly different approach. In the Dropdownlist i used the Model and then referenced it. Not sure if this was what you were looking for.

@Html.DropDownList("Example", new SelectList(Model.FeeStructures, "Id", "NameOfFeeStructure", Model.Matters.FeeStructures))

Model.Matters.FeeStructures in above is my id, which could be your value of the item that should be selected.

Assuming you are using this for a web service, you can just apply the following attribute to the class:

[System.Web.Script.Services.ScriptService]

Then the following attribute to each method that should return Json:

[ScriptMethod(ResponseFormat = ResponseFormat.Json)]

And set the return type for the methods to be "object"

HTML

<body>
    <div id="load"></div>
    <div id="contents">
          jlkjjlkjlkjlkjlklk
    </div>
</body>

JS

document.onreadystatechange = function () {
  var state = document.readyState
  if (state == 'interactive') {
       document.getElementById('contents').style.visibility="hidden";
  } else if (state == 'complete') {
      setTimeout(function(){
         document.getElementById('interactive');
         document.getElementById('load').style.visibility="hidden";
         document.getElementById('contents').style.visibility="visible";
      },1000);
  }
}

CSS

#load{
    width:100%;
    height:100%;
    position:fixed;
    z-index:9999;
    background:url("https://www.creditmutuel.fr/cmne/fr/banques/webservices/nswr/images/loading.gif") no-repeat center center rgba(0,0,0,0.25)
}

Note:
you wont see any loading gif if your page is loaded fast, so use this code on a page with high loading time, and i also recommend to put your js on the bottom of the page.

RFC 6265 was published in 2011, based on the browser consensus at that time. Since then, there has been some complication with public suffix domains. I've written an article explaining the current situation - http://bayou.io/draft/cookie.domain.html

To summarize, rules to follow regarding cookie domain:

• The origin domain of a cookie is the domain of the originating request.

• If the origin domain is an IP, the cookie's domain attribute must not be set.

• If a cookie's domain attribute is not set, the cookie is only applicable to its origin domain.

• If a cookie's domain attribute is set,

  • the cookie is applicable to that domain and all its subdomains;
  • the cookie's domain must be the same as, or a parent of, the origin domain
  • the cookie's domain must not be a TLD, a public suffix, or a parent of a public suffix.

It can be derived that a cookie is always applicable to its origin domain.

The cookie domain should not have a leading dot, as in .foo.com - simply use foo.com

As an example,

• x.y.z.com can set a cookie domain to itself or parents - x.y.z.com, y.z.com, z.com. But not com, which is a public suffix.
• a cookie with domain=y.z.com is applicable to y.z.com, x.y.z.com, a.x.y.z.com etc.

Examples of public suffixes - com, edu, uk, co.uk, blogspot.com, compute.amazonaws.com

It explains the pros and cons of different methods of creating PreparedStatement with in clause.

EDIT:

An obvious approach is to dynamically generate the '?' part at runtime, but I don't want to merely suggest just this approach because depending on the way you use it, it might be inefficient (since the PreparedStatement will need to be 'compiled' every time it gets used)

First: I'm surprised that no one has mentioned fabric yet.

Second: For exactly those requirements you describe I've implemented an own python module named jk_simpleexec. It's purpose: Making running commands easy.

Let me explain a little bit about it for you.

The 'executing a command locally' problem

My python module jk_simpleexec provides a function named runCmd(..) that can execute a shell (!) command locally or remotely. This is very simple. Here is an example for local execution of a command:

import jk_simpleexec

cmdResult = jk_simpleexec.runCmd(None, "cd / ; ls -la")

NOTE: Be aware that the returned data is trimmed automatically by default to remove excessive empty lines from STDOUT and STDERR. (Of course this behavior can be deactivated, but for the purpose you've in mind exactly that behavior is what you will want.)

The 'processing the result' problem

What you will receive is an object that contains the return code, STDOUT and STDERR. Therefore it's very easy to process the result.

And this is what you want to do as the command you execute might exist and is launched but might fail in doing what it is intended to do. In the most simple case where you're not interested in STDOUT and STDERR your code will likely look something like this:

cmdResult.raiseExceptionOnError("Something went wrong!", bDumpStatusOnError=True)

For debugging purposes you want to output the result to STDOUT at some time, so for this you can do just this:

cmdResult.dump()

If you would want to process STDOUT it's simple as well. Example:

The 'executing a command remotely' problem

Now of course we might want to execute this command remotely on another system. For this we can use the same function runCmd(..) in exactly the same way but we need to specify a fabric connection object first. This can be done like this:

from fabric import Connection

REMOTE_HOST = "myhost"
REMOTE_PORT = 22
REMOTE_LOGIN = "mylogin"
REMOTE_PASSWORD = "mypwd"
c = Connection(host=REMOTE_HOST, user=REMOTE_LOGIN, port=REMOTE_PORT, connect_kwargs={"password": REMOTE_PASSWORD})

cmdResult = jk_simpleexec.runCmd(c, "cd / ; ls -la")

# ... process the result stored in cmdResult ...

c.close()

Everything remains exactly the same, but this time we run this command on another host. This is intended: I wanted to have a uniform API where there are no modifications required in the software if you at some time decide to move from the local host to another host.

The password input problem

Now of course there is the password problem. This has been mentioned above by some users: We might want to ask the user executing this python code for a password.

For this problem I have created an own module quite some time ago. jk_pwdinput. The difference to regular password input is that jk_pwdinput will output some stars instead of just printing nothing. So for every password character you type you will see a star. This way it's more easy for you to enter a password.

Here is the code:

import jk_pwdinput

# ... define other 'constants' such as REMOTE_LOGIN, REMOTE_HOST ...

REMOTE_PASSWORD = jk_pwdinput.readpwd("Password for " + REMOTE_LOGIN + "@" + REMOTE_HOST + ": ")

(For completeness: If readpwd(..) returned None the user canceled the password input with Ctrl+C. In a real world scenario you might want to act on this appropriately.)

Full example

Here is a full example:

import jk_simpleexec
import jk_pwdinput
from fabric import Connection

REMOTE_HOST = "myhost"
REMOTE_PORT = 22
REMOTE_LOGIN = "mylogin"
REMOTE_PASSWORD = jk_pwdinput.readpwd("Password for " + REMOTE_LOGIN + "@" + REMOTE_HOST + ": ")
c = Connection(host=REMOTE_HOST, user=REMOTE_LOGIN, port=REMOTE_PORT, connect_kwargs={"password": REMOTE_PASSWORD})

cmdResult = jk_simpleexec.runCmd(
    c = c,
    command = "cd / ; ls -la"
)
cmdResult.raiseExceptionOnError("Something went wrong!", bDumpStatusOnError=True)

c.close()

Final notes

So we have the full set:

• Executing a command,
• executing that command remotely via the same API,
• creating the connection in an easy and secure way with password input.

The code above solves the problem quite well for me (and hopefully for you as well). And everything is open source: Fabric is BSD-2-Clause, and my own modules are provided under Apache-2.

Modules used:

• fabric : http://www.fabfile.org/
• jk_pwdinput : https://github.com/jkpubsrc/python-module-jk-pwdinput
• jk_simplexec : https://github.com/jkpubsrc/python-module-jk-simpleexec

Happy coding! ;-)

You might want to check your matplotlib version.

Somehow I installed a dev version of matplotlib which caused the issue. A downgrade to stable release fixed it.

One can also can try python -v -c 'import YOUR_PACKAGE' 2>&1 | less to see where the issue occurred and if the lines above error can give you some hints.

Directly, you can't, and that's a good thing. The browser's alert is there for a reason. This thread should answer your question:

Prevent Back button from showing POST confirmation alert

Two key workarounds suggested were the PRG pattern, and an AJAX submit followed by a scripting relocation.

Note that if your method allows for a GET and not a POST submission method, then that would both solve the problem and better fit with convention. Those solutions are provided on the assumption you want/need to POST data.

Since I got here with my problem I will add this answer although it is not exactly relevant to the original question. When you are implementing an interface make sure you do not forget to add the type pointer on your member function declarations. Example:

type AnimalSounder interface {
    MakeNoise()
}

type Dog struct {
    Name string
    mean bool
    BarkStrength int
}

func (dog *Dog) MakeNoise() {
    //implementation
}

I forgot the *(dog Dog) part, I do not recommend it. Then you get into ugly trouble when calling MakeNoice on an AnimalSounder interface variable of type Dog.

var textToFind = 'Google';

var dd = document.getElementById('MyDropDown');
for (var i = 0; i < dd.options.length; i++) {
    if (dd.options[i].text === textToFind) {
        dd.selectedIndex = i;
        break;
    }
}

For me the easiest solution was this:

map.fitBounds(bounds);

function set_zoom() {
    if(map.getZoom()) {map.setZoom(map.getZoom() - 1);}
    else {setTimeout(set_zoom, 5);}
}
setTimeout(set_zoom, 5);

You can't use ^ and $ in character classes in the way you wish - they will be interpreted literally, but you can use an alternation to achieve the same effect:

(^|,)garp(,|$)

It depends mostly on how much the repository is used. With one user checking in once a day and a branch/merge/etc operation once a week you probably don't need to run it more than once a year.

With several dozen developers working on several dozen projects each checking in 2-3 times a day, you might want to run it nightly.

It won't hurt to run it more frequently than needed, though.

What I'd do is run it now, then a week from now take a measurement of disk utilization, run it again, and measure disk utilization again. If it drops 5% in size, then run it once a week. If it drops more, then run it more frequently. If it drops less, then run it less frequently.

The breakdown of your declaration and its members is somewhat littered:

Remove the typedef

The typedef is neither required, not desired for class/struct declarations in C++. Your members have no knowledge of the declaration of pos as-written, which is core to your current compilation failure.

Change this:

typedef struct {....} pos;

To this:

struct pos { ... };

Remove extraneous inlines

You're both declaring and defining your member operators within the class definition itself. The inline keyword is not needed so long as your implementations remain in their current location (the class definition)

Return references to *this where appropriate

This is related to an abundance of copy-constructions within your implementation that should not be done without a strong reason for doing so. It is related to the expression ideology of the following:

a = b = c;

This assigns c to b, and the resulting value b is then assigned to a. This is not equivalent to the following code, contrary to what you may think:

a = c;
b = c;

Therefore, your assignment operator should be implemented as such:

pos& operator =(const pos& a)
{
    x = a.x;
    y = a.y;
    return *this;
}

Even here, this is not needed. The default copy-assignment operator will do the above for you free of charge (and code! woot!)

Note: there are times where the above should be avoided in favor of the copy/swap idiom. Though not needed for this specific case, it may look like this:

pos& operator=(pos a) // by-value param invokes class copy-ctor
{
    this->swap(a);
    return *this;
}

Then a swap method is implemented:

void pos::swap(pos& obj)
{
    // TODO: swap object guts with obj
}

You do this to utilize the class copy-ctor to make a copy, then utilize exception-safe swapping to perform the exchange. The result is the incoming copy departs (and destroys) your object's old guts, while your object assumes ownership of there's. Read more the copy/swap idiom here, along with the pros and cons therein.

Pass objects by const reference when appropriate

All of your input parameters to all of your members are currently making copies of whatever is being passed at invoke. While it may be trivial for code like this, it can be very expensive for larger object types. An exampleis given here:

Change this:

bool operator==(pos a) const{
    if(a.x==x && a.y== y)return true;
    else return false;
}

To this: (also simplified)

bool operator==(const pos& a) const
{
    return (x == a.x && y == a.y);
}

No copies of anything are made, resulting in more efficient code.

Finally, in answering your question, what is the difference between a member function or operator declared as const and one that is not?

A const member declares that invoking that member will not modifying the underlying object (mutable declarations not withstanding). Only const member functions can be invoked against const objects, or const references and pointers. For example, your operator +() does not modify your local object and thus should be declared as const. Your operator =() clearly modifies the local object, and therefore the operator should not be const.

Summary

struct pos
{
    int x;
    int y;

    // default + parameterized constructor
    pos(int x=0, int y=0) 
        : x(x), y(y)
    {
    }

    // assignment operator modifies object, therefore non-const
    pos& operator=(const pos& a)
    {
        x=a.x;
        y=a.y;
        return *this;
    }

    // addop. doesn't modify object. therefore const.
    pos operator+(const pos& a) const
    {
        return pos(a.x+x, a.y+y);
    }

    // equality comparison. doesn't modify object. therefore const.
    bool operator==(const pos& a) const
    {
        return (x == a.x && y == a.y);
    }
};

EDIT OP wanted to see how an assignment operator chain works. The following demonstrates how this:

a = b = c;

Is equivalent to this:

b = c;
a = b;

And that this does not always equate to this:

a = c;
b = c;

Sample code:

#include <iostream>
#include <string>
using namespace std;

struct obj
{
    std::string name;
    int value;

    obj(const std::string& name, int value)
        : name(name), value(value)
    {
    }

    obj& operator =(const obj& o)
    {
        cout << name << " = " << o.name << endl;
        value = (o.value+1); // note: our value is one more than the rhs.
        return *this;
    }    
};

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

    obj a("a", 1), b("b", 2), c("c", 3);

    a = b = c;
    cout << "a.value = " << a.value << endl;
    cout << "b.value = " << b.value << endl;
    cout << "c.value = " << c.value << endl;

    a = c;
    b = c;
    cout << "a.value = " << a.value << endl;
    cout << "b.value = " << b.value << endl;
    cout << "c.value = " << c.value << endl;

    return 0;
}

Output

b = c
a = b
a.value = 5
b.value = 4
c.value = 3
a = c
b = c
a.value = 4
b.value = 4
c.value = 3

Suggest you add handling to test if any of the sheets to be renamed already exist:

Sub Test()

Dim ws As Worksheet
Dim ws1 As Worksheet
Dim strErr As String

On Error Resume Next
For Each ws In ActiveWorkbook.Sheets
Set ws1 = Sheets(ws.Name & "_v1")
    If ws1 Is Nothing Then
        ws.Name = ws.Name & "_v1"
    Else
         strErr = strErr & ws.Name & "_v1" & vbNewLine
    End If
Set ws1 = Nothing
Next
On Error GoTo 0

If Len(strErr) > 0 Then MsgBox strErr, vbOKOnly, "these sheets already existed"

End Sub

The following lines should be updated in app -> main -> res -> values -> Styles.xml

 <!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    <item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item>
</style>

<!-- Style to replace actionbar overflow icon. set item 'android:actionOverflowButtonStyle' in AppTheme -->
<style name="MyActionButtonOverflow" parent="android:style/Widget.Holo.Light.ActionButton.Overflow">
    <item name="android:src">@drawable/ic_launcher</item>
    <item name="android:background">?android:attr/actionBarItemBackground</item>
    <item name="android:contentDescription">"Lala"</item>
</style>

This is how it can be done. If you want to change the overflow icon in action bar

Be careful of difference between 'c' and "c"

'c' is a char suitable for formatting with %c

"c" is a char* pointing to a memory block with a length of 2 (with the null terminator).

Just to add to Scott Sauyet's answer, some people were asking in the comments how to use his function to groupby value1, value2, etc., instead of grouping just one value.

All it takes is to edit his sum function:

DataGrouper.register("sum", function(item) {
    return _.extend({}, item.key,
        {VALUE1: _.reduce(item.vals, function(memo, node) {
        return memo + Number(node.VALUE1);}, 0)},
        {VALUE2: _.reduce(item.vals, function(memo, node) {
        return memo + Number(node.VALUE2);}, 0)}
    );
});

leaving the main one (DataGrouper) unchanged:

var DataGrouper = (function() {
    var has = function(obj, target) {
        return _.any(obj, function(value) {
            return _.isEqual(value, target);
        });
    };

    var keys = function(data, names) {
        return _.reduce(data, function(memo, item) {
            var key = _.pick(item, names);
            if (!has(memo, key)) {
                memo.push(key);
            }
            return memo;
        }, []);
    };

    var group = function(data, names) {
        var stems = keys(data, names);
        return _.map(stems, function(stem) {
            return {
                key: stem,
                vals:_.map(_.where(data, stem), function(item) {
                    return _.omit(item, names);
                })
            };
        });
    };

    group.register = function(name, converter) {
        return group[name] = function(data, names) {
            return _.map(group(data, names), converter);
        };
    };

    return group;
}());

Actually we were wrong.
Despite Java doesn't allow you to override static methods by default, if you look thoroughly through documentation of Class and Method classes in Java, you can still find a way to emulate static methods overriding by following workaround:

import java.lang.reflect.InvocationTargetException;
import java.math.BigDecimal;

class RegularEmployee {

    private BigDecimal salary = BigDecimal.ONE;

    public void setSalary(BigDecimal salary) {
        this.salary = salary;
    }
    public static BigDecimal getBonusMultiplier() {
        return new BigDecimal(".02");
    }
    public BigDecimal calculateBonus() {
        return salary.multiply(this.getBonusMultiplier());
    }
    public BigDecimal calculateOverridenBonus() {
        try {
            // System.out.println(this.getClass().getDeclaredMethod(
            // "getBonusMultiplier").toString());
            try {
                return salary.multiply((BigDecimal) this.getClass()
                    .getDeclaredMethod("getBonusMultiplier").invoke(this));
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            } catch (IllegalArgumentException e) {
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                e.printStackTrace();
            }
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (SecurityException e) {
            e.printStackTrace();
        }
        return null;
    }
    // ... presumably lots of other code ...
}

final class SpecialEmployee extends RegularEmployee {

    public static BigDecimal getBonusMultiplier() {
        return new BigDecimal(".03");
    }
}

public class StaticTestCoolMain {

    static public void main(String[] args) {
        RegularEmployee Alan = new RegularEmployee();
        System.out.println(Alan.calculateBonus());
        System.out.println(Alan.calculateOverridenBonus());
        SpecialEmployee Bob = new SpecialEmployee();
        System.out.println(Bob.calculateBonus());
        System.out.println(Bob.calculateOverridenBonus());
    }
}

Resulting output:

0.02
0.02
0.02
0.03

what we were trying to achieve :)

Even if we declare third variable Carl as RegularEmployee and assign to it instance of SpecialEmployee, we will still have call of RegularEmployee method in first case and call of SpecialEmployee method in second case

RegularEmployee Carl = new SpecialEmployee();

System.out.println(Carl.calculateBonus());
System.out.println(Carl.calculateOverridenBonus());

just look at output console:

0.02
0.03

;)

A better alternative to Control Panel is to use this freeware program from SourceForge called Pathenator.

However, it only works for a system that has .NET 4.0 or greater such as Windows 7, Windows 8, or Windows 10.

Look up the specification of HTTP. Or to get started, try http://www.jmarshall.com/easy/http/

When you have many HTML inputs named C[] what you get in the POST array on the other end is an array of these values in $_POST['C']. So when you echo that, you are trying to print an array, so all it does is print Array and a notice.

To print properly an array, you either loop through it and echo each element, or you can use print_r.

Alternatively, if you don't know if it's an array or a string or whatever, you can use var_dump($var) which will tell you what type it is and what it's content is. Use that for debugging purposes only.

If you really don't want to use numpy you can do something like this:

def matmult(a,b):
    zip_b = zip(*b)
    # uncomment next line if python 3 : 
    # zip_b = list(zip_b)
    return [[sum(ele_a*ele_b for ele_a, ele_b in zip(row_a, col_b)) 
             for col_b in zip_b] for row_a in a]

x = [[1,2,3],[4,5,6],[7,8,9],[10,11,12]]
y = [[1,2],[1,2],[3,4]]

import numpy as np # I want to check my solution with numpy

mx = np.matrix(x)
my = np.matrix(y)       

Result:

>>> matmult(x,y)
[[12, 18], [27, 42], [42, 66], [57, 90]]
>>> mx * my
matrix([[12, 18],
        [27, 42],
        [42, 66],
        [57, 90]])

You could also put non-breaking spaces ( ) in lieu of the spaces so that they're forced to stay together.

How do I wrap this line of text
- asked by Peter 2 days ago

You have to pass the route parameters to the route method, for example:

<li><a href="{{ route('user.profile', $nickname) }}">Profile</a></li>
<li><a href="{{ route('user.settings', $nickname) }}">Settings</a></li>

It's because, both routes have a {nickname} in the route declaration. I've used $nickname for example but make sure you change the $nickname to appropriate value/variable, for example, it could be something like the following:

<li><a href="{{ route('user.settings', auth()->user()->nickname) }}">Settings</a></li>

I thought one of the main differences was that in MVC, your V reads your M directly, and goes via the C to manipulate the data, whereas in MVVM, your VM acts as an M proxy, as well as providing the available functionality to you V.

If I'm not full of junk, I'm surprised no one has created a hybrid, where your VM is merely a M proxy, and C provides all functionality.

<style>
body {
     visibility:hidden
}
body .moz-signature p{

}
</style>

The above works well in latest Thunderbird also.

String s = "3.14";
float f = Float.parseFloat(s);

just simply (PowerShell V5)

Get-ChildItem "C:\temp" -Recurse -File | Where CreationTime -lt  (Get-Date).AddDays(-15)  | Remove-Item -Force

Here's another option, which is less efficient but more concise. It's how I generally handle this sort of problem:

Get-ChildItem -Recurse .\targetdir -Exclude *.log |
  Where-Object { $_.FullName -notmatch '\\excludedir($|\\)' }

The \\excludedir($|\\)' expression allows you to exclude the directory and its contents at the same time.

Update: Please check the excellent answer from msorens for an edge case flaw with this approach, and a much more fleshed out solution overall.

It Doesn't work in Laravel 5.3+ if you want to try to access the value from the controller like below. It always returns null

<?php

    $value = env('MY_VALUE', 'default_value');

SOLUTION: Rather, you need to create a file in the configuration folder, say values.php and then write the code like below

File values.php

<?php

    return [

        'myvalue' => env('MY_VALUE',null),

        // Add other values as you wish

Then access the value in your controller with the following code

<?php

    $value = \Config::get('values.myvalue')

Where "values" is the filename followed by the key "myvalue".

def head(iterable):
    try:
        return iter(iterable).next()
    except StopIteration:
        return None

print head(xrange(42, 1000)  # 42
print head([])               # None

BTW: I'd rework your general program flow into something like this:

lists = [
    ["first", "list"],
    ["second", "list"],
    ["third", "list"]
]

def do_something(element):
    if not element:
        return
    else:
        # do something
        pass

for li in lists:
    do_something(head(li))

(Avoiding repetition whenever possible)

Using Guava (r07) you can do this:

for(char c : Lists.charactersOf(someString)) { ... }

This has the convenience of using foreach while not copying the string to a new array. Lists.charactersOf returns a view of the string as a List.

Set the default time zone first and get the date then, the date will be in the time zone you specify :

<?php 
 date_default_timezone_set('America/New_York');
 $date= date('m-d-Y') ;
 ?>

Why not:

<button type="submit">
<img src="mybutton.jpg" />
</button>

If you are running windows try this:

1. click start button on a keyboard
2. type task manager
3. right click and click run as administrator when the task manager opens
4. click on services then look for MySQL then
5. right click on it then click stop then close task manager and you are done.

to start it when you wand to use it, follow the same steps and click start this time

Firstly, the level name to use is FINE, not DEBUG. Let's assume for a minute that DEBUG is actually valid, as it makes the following explanation make a bit more sense...

In the Handler specific properties section, you're setting the logging level for those handlers to DEBUG. This means the handlers will handle any log messages with the DEBUG level or higher. It doesn't necessarily mean any DEBUG messages are actually getting passed to the handlers.

In the Facility specific properties section, you're setting the logging level for a few explicitly-named loggers to DEBUG. For those loggers, anything at level DEBUG or above will get passed to the handlers.

The default logging level is INFO, and apart from the loggers mentioned in the Facility specific properties section, all loggers will have that level.

If you want to see all FINE messages, add this:

.level = FINE

However, this will generate a vast quantity of log messages. It's probably more useful to set the logging level for your code:

your.package.level = FINE

See the Tomcat 6/Tomcat 7 logging documentation for more information. The example logging.properties file shown there uses FINE instead of DEBUG:

...
1catalina.org.apache.juli.FileHandler.level = FINE
...

and also gives you examples of setting additional logging levels:

# For example, set the com.xyz.foo logger to only log SEVERE
# messages:
#org.apache.catalina.startup.ContextConfig.level = FINE
#org.apache.catalina.startup.HostConfig.level = FINE
#org.apache.catalina.session.ManagerBase.level = FINE

The Java EE version of Eclipse is not installed, insted a standard SDK version is installed.

You can go to Help > Install New Software then select the Eclipse site from the dropdown (Helios, Kepler depending upon your revision). Then select the option that shows Java EE. Restart Eclipse and you should see the Server list, such as Apache, Oracle, IBM etc.

You need add parameter errors='coerce' to function to_numeric:

ID = pd.to_numeric(ID, errors='coerce')

If ID is column:

df.ID = pd.to_numeric(df.ID, errors='coerce')

but non numeric are converted to NaN, so all values are float.

For int need convert NaN to some value e.g. 0 and then cast to int:

df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)

Sample:

df = pd.DataFrame({'ID':['4806105017087','4806105017087','CN414149']})
print (df)
              ID
0  4806105017087
1  4806105017087
2       CN414149

print (pd.to_numeric(df.ID, errors='coerce'))
0    4.806105e+12
1    4.806105e+12
2             NaN
Name: ID, dtype: float64

df.ID = pd.to_numeric(df.ID, errors='coerce').fillna(0).astype(np.int64)
print (df)
              ID
0  4806105017087
1  4806105017087
2              0

EDIT: If use pandas 0.25+ then is possible use integer_na:

df.ID = pd.to_numeric(df.ID, errors='coerce').astype('Int64')
print (df)
              ID
0  4806105017087
1  4806105017087
2            NaN

Linq equivalents of Map and Reduce: If you’re lucky enough to have linq then you don’t need to write your own map and reduce functions. C# 3.5 and Linq already has it albeit under different names.

• Map is Select:

  Enumerable.Range(1, 10).Select(x => x + 2);
  

• Reduce is Aggregate:

  Enumerable.Range(1, 10).Aggregate(0, (acc, x) => acc + x);
  

• Filter is Where:

  Enumerable.Range(1, 10).Where(x => x % 2 == 0);

Use the $ metacharacter to match the end of a string.

In Perl, this looks like:

my $str = 'red/white/blue';
my($last_match) = $str =~ m/.*\/(.*)$/;

Written in JavaScript, this looks like:

var str = 'red/white/blue'.match(/.*\/(.*)$/);

Please change only the name of the function; no other change is required

You might need to activate adb root from the developer settings menu. If you run adb root from the cmd line you can get:

root access is disabled by system setting - enable in settings -> development options

Once you activate the root option (ADB only or Apps and ADB) adb will restart and you will be able to use root from the cmd line.

To have greater control of the track color (no API controlled alpha changes), I extended SwitchCompat and style the elements programmatically:

    public class CustomizedSwitch extends SwitchCompat {

    public CustomizedSwitch(Context context) {
        super(context);
        initialize(context);
    }

    public CustomizedSwitch(Context context, AttributeSet attrs) {
        super(context, attrs);
        initialize(context);
    }

    public CustomizedSwitch(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initialize(context);
    }

    public void initialize(Context context) {
        // DisplayMeasurementConverter is just a utility to convert from dp to px and vice versa
        DisplayMeasurementConverter displayMeasurementConverter = new DisplayMeasurementConverter(context);
        // Sets the width of the switch
        this.setSwitchMinWidth(displayMeasurementConverter.dpToPx((int) getResources().getDimension(R.dimen.tp_toggle_width)));
        // Setting up my colors
        int mediumGreen = ContextCompat.getColor(context, R.color.medium_green);
        int mediumGrey = ContextCompat.getColor(context, R.color.medium_grey);
        int alphaMediumGreen = Color.argb(127, Color.red(mediumGreen), Color.green(mediumGreen), Color.blue(mediumGreen));
        int alphaMediumGrey = Color.argb(127, Color.red(mediumGrey), Color.green(mediumGrey), Color.blue(mediumGrey));
        // Sets the tints for the thumb in different states
        DrawableCompat.setTintList(this.getThumbDrawable(), new ColorStateList(
                new int[][]{
                        new int[]{android.R.attr.state_checked},
                        new int[]{}
                },
                new int[]{
                        mediumGreen,
                        ContextCompat.getColor(getContext(), R.color.light_grey)
                }));
        // Sets the tints for the track in different states
        DrawableCompat.setTintList(this.getTrackDrawable(), new ColorStateList(
                new int[][]{
                        new int[]{android.R.attr.state_checked},
                        new int[]{}
                },
                new int[]{
                        alphaMediumGreen,
                        alphaMediumGrey
                }));
    }
}

Whenever I want to use the CustomizedSwitch, I just add one to my xml file.

You don't really need any JavaScript with Bootstrap:

 <ul class="nav">
     <li><a data-target="#" data-toggle="pill" href="#accounts">Accounts</a></li>
     <li><a data-target="#" data-toggle="pill" href="#users">Users</a></li>
 </ul>

To do more tasks after the menu item is selected you need JS as explained by other posts here.

Hope this helps.

You need to declare @font-face like this in your stylesheet

@font-face {
  font-family: 'Awesome-Font';
  font-style: normal;
  font-weight: 400;
  src: local('Awesome-Font'), local('Awesome-Font-Regular'), url(path/Awesome-Font.woff) format('woff');
}

Now if you want to apply this font to a paragraph simply use it like this..

p {
font-family: 'Awesome-Font', Arial;
}

More Reference

You can also remove files from the repository based on your .gitignore without deleting them from the local file system :

git rm --cached `git ls-files -i -X .gitignore`

Or, alternatively, on Windows Powershell:

git rm --cached $(git ls-files -i -X .gitignore)

Java passes by value; there's no out parameter like in C#.

You can either use return, or mutate an object passed as a reference (by value).

Related questions

• Does Java have something like C#'s ref and out keywords? ? (NO!)
• Is Java pass by reference? (NO!)

Code sample

public class FunctionSample {
    static String fReturn() {
        return "Hello!";
    }
    static void fArgNoWorkie(String s) {
        s = "What am I doing???"; // Doesn't "work"! Java passes by value!
    }
    static void fMutate(StringBuilder sb) {
        sb.append("Here you go!");
    }
    public static void main(String[] args) {
        String s = null;

        s = fReturn();
        System.out.println(s); // prints "Hello!"

        fArgNoWorkie(s);
        System.out.println(s); // prints "Hello!"

        StringBuilder sb = new StringBuilder();
        fMutate(sb);
        s = sb.toString();
        System.out.println(s); // prints "Here you go!"
    }

}

• What is meant by immutable?
• StringBuilder and StringBuffer in Java

As for the code that OP needs help with, here's a typical solution of using a special value (usually null for reference types) to indicate success/failure:

Instead of:

String oPerson= null;
if (CheckAddress("5556", oPerson)) {
   print(oPerson); // DOESN'T "WORK"! Java passes by value; String is immutable!
}

private boolean CheckAddress(String iAddress, String oPerson) {
   // on search succeeded:
   oPerson = something; // DOESN'T "WORK"!
   return true;
   :
   // on search failed:
   return false;
}

Use a String return type instead, with null to indicate failure.

String person = checkAddress("5556");
if (person != null) {
   print(person);
}

private String checkAddress(String address) {
   // on search succeeded:
   return something;
   :
   // on search failed:
   return null;
}

This is how java.io.BufferedReader.readLine() works, for example: it returns instanceof String (perhaps an empty string!), until it returns null to indicate end of "search".

This is not limited to a reference type return value, of course. The key is that there has to be some special value(s) that is never a valid value, and you use that value for special purposes.

Another classic example is String.indexOf: it returns -1 to indicate search failure.

Note: because Java doesn't have a concept of "input" and "output" parameters, using the i- and o- prefix (e.g. iAddress, oPerson) is unnecessary and unidiomatic.

A more general solution

If you need to return several values, usually they're related in some way (e.g. x and y coordinates of a single Point). The best solution would be to encapsulate these values together. People have used an Object[] or a List<Object>, or a generic Pair<T1,T2>, but really, your own type would be best.

For this problem, I recommend an immutable SearchResult type like this to encapsulate the boolean and String search results:

public class SearchResult {
   public final String name;
   public final boolean isFound;

   public SearchResult(String name, boolean isFound) {
      this.name = name;
      this.isFound = isFound;
   }
}

Then in your search function, you do the following:

private SearchResult checkAddress(String address) {
  // on address search succeed
  return new SearchResult(foundName, true);
  :
  // on address search failed
  return new SearchResult(null, false);
}

And then you use it like this:

SearchResult sr = checkAddress("5556");
if (sr.isFound) {
  String name = sr.name;
  //...
}

If you want, you can (and probably should) make the final immutable fields non-public, and use public getters instead.

This is called type conversion :

i := 23
var i64 int64
i64 = int64(i)

That is because FirstOrDefaultcan return null causing your following .Value to cause the exception. You need to change it to something like:

var myThing = things.FirstOrDefault(t => t.Id == idToFind);

if(myThing == null)
    return; // we failed to find what we wanted
var displayName = myThing.DisplayName;

You will need wrapper classes:

public class SomeIntInfo
{
    [XmlAttribute]
    public int Value { get; set; }
}

public class SomeStringInfo
{
    [XmlAttribute]
    public string Value { get; set; }
}

public class SomeModel
{
    [XmlElement("SomeStringElementName")]
    public SomeStringInfo SomeString { get; set; }

    [XmlElement("SomeInfoElementName")]
    public SomeIntInfo SomeInfo { get; set; }
}

or a more generic approach if you prefer:

public class SomeInfo<T>
{
    [XmlAttribute]
    public T Value { get; set; }
}

public class SomeModel
{
    [XmlElement("SomeStringElementName")]
    public SomeInfo<string> SomeString { get; set; }

    [XmlElement("SomeInfoElementName")]
    public SomeInfo<int> SomeInfo { get; set; }
}

And then:

class Program
{
    static void Main()
    {
        var model = new SomeModel
        {
            SomeString = new SomeInfo<string> { Value = "testData" },
            SomeInfo = new SomeInfo<int> { Value = 5 }
        };
        var serializer = new XmlSerializer(model.GetType());
        serializer.Serialize(Console.Out, model);
    }
}

will produce:

<?xml version="1.0" encoding="ibm850"?>
<SomeModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <SomeStringElementName Value="testData" />
  <SomeInfoElementName Value="5" />
</SomeModel>

It's looking like Firefox and Opera (tested on mac as well) don't like the cross domainness of this (but Safari is fine with it).

You might have to call a local server side code to curl the remote page.

I'm not sure what you're going for here--by the time jQuery(document).ready() has executed, it has already loaded, and thus document's load event will already have been called. Attaching the load event handler at this point will have no effect and it will never be called. If you're attempting to alert "started" once the document has loaded, just put it right in the (document).ready() call, like this:

jQuery(document).ready(function() {
    var x = $('#initial').html();
    $('#add').click(function() {
        $('body').append(x);
    });

    alert('started');

});?

If, as your code also appears to insinuate, you want to fire the alert when .abc has loaded, put it in an individual .load handler:

jQuery(document).ready(function() {
    var x = $('#initial').html();
    $('#add').click(function() {
        $('body').append(x);
    });

    $(".abc").on("load", function() {
        alert('started');
    }
});?

Finally, I see little point in using jQuery in one place and $ in another. It's generally better to keep your code consistent, and either use jQuery everywhere or $ everywhere, as the two are generally interchangeable.

Following is a Java-Spark way to do it , 1) add a sequentially increment columns. 2) Select Row number using Id. 3) Drop the Column

import static org.apache.spark.sql.functions.*;
..

ds = ds.withColumn("rownum", functions.monotonically_increasing_id());
ds = ds.filter(col("rownum").equalTo(99));
ds = ds.drop("rownum");

N.B. monotonically_increasing_id starts from 0;

If MS has not updated to C99, MY_TYPE a = { true,15,0.123 };

Another example if you are using Titanium Alloy:

 collection.fetch({ 
     data: {
             where : JSON.stringify({
                page: 1
             })
           } 
      });

Possible solutions for code that deal with RTTI and non-RTTI libraries:

a) Recompile everything with either -frtti or -fno-rtti
b) If a) is not possible for you, try the following:

Assume libfoo is built without RTTI. Your code uses libfoo and compiles with RTTI. If you use a class (Foo) in libfoo that has virtuals, you're likely to run into a link-time error that says: missing typeinfo for class Foo.

Define another class (e.g. FooAdapter) that has no virtual and will forward calls to Foo that you use.

Compile FooAdapter in a small static library that doesn't use RTTI and only depends on libfoo symbols. Provide a header for it and use that instead in your code (which uses RTTI). Since FooAdapter has no virtual function it won't have any typeinfo and you'll be able to link your binary. If you use a lot of different classes from libfoo, this solution may not be convenient, but it's a start.

Just want to share another option:

# mark two objects to be deleted
session.delete(obj1)
session.delete(obj2)

# commit (or flush)
session.commit()

http://docs.sqlalchemy.org/en/latest/orm/session_basics.html#deleting

In this example, the following codes shall works fine:

obj = User.query.filter_by(id=123).one()
session.delete(obj)
session.commit()

using row major example:

A(i,j) = a[i + j*ld]; // where ld is the leading dimension
                      // (commonly same as array dimension in i)

// matrix like notation using preprocessor hack, allows to hide indexing
#define A(i,j) A[(i) + (j)*ld]

double *A = ...;
size_t ld = ...;
A(i,j) = ...;
... = A(j,i);

I had the same problem. Spent quite some time searching for an answer and found my own solution: Add following text to the head:

<style type="text/css">
    .popover{
        max-width:600px;
    }
</style>

The XPath spec. defines the string value of an element as the concatenation (in document order) of all of its text-node descendents.

This explains the "strange results".

"Better" results can be obtained using the expressions below:

//*[text() = 'qwerty']

The above selects every element in the document that has at least one text-node child with value 'qwerty'.

//*[text() = 'qwerty' and not(text()[2])]

The above selects every element in the document that has only one text-node child and its value is: 'qwerty'.

// Use any date you want, for the purpose of this example we use 1980-08-03.
var myDate = new DateTime(1980,8,3);
var lastDayOfMonth = new DateTime(myDate.Year, myDate.Month, DateTime.DaysInMonth(myDate.Year, myDate.Month));

Along the lines of Guava, Apache Commons Lang has ExceptionUtils.getFullStackTrace in org.apache.commons.lang.exception. From a prior answer on StackOverflow.

You can make a cookie never end by setting it to whatever date plus one more than the current year like this :

var d = new Date();    
document.cookie = "username=John Doe; expires=Thu, 18 Dec " + (d.getFullYear() + 1) + " 12:00:00 UTC";

This will dismiss the keyboardwhen you touch anywhere in the background.

    <?php
if (isset($_POST['birthdate'])) {

    $date=date('d',$timestamp);
    $month=date('m',$timestamp);
    $year=date('Y',$timestamp);
}
?>  

A simple way using std::next_permutation:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
    int n, r;
    std::cin >> n;
    std::cin >> r;

    std::vector<bool> v(n);
    std::fill(v.end() - r, v.end(), true);

    do {
        for (int i = 0; i < n; ++i) {
            if (v[i]) {
                std::cout << (i + 1) << " ";
            }
        }
        std::cout << "\n";
    } while (std::next_permutation(v.begin(), v.end()));
    return 0;
}

or a slight variation that outputs the results in an easier to follow order:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
   int n, r;
   std::cin >> n;
   std::cin >> r;

   std::vector<bool> v(n);
   std::fill(v.begin(), v.begin() + r, true);

   do {
       for (int i = 0; i < n; ++i) {
           if (v[i]) {
               std::cout << (i + 1) << " ";
           }
       }
       std::cout << "\n";
   } while (std::prev_permutation(v.begin(), v.end()));
   return 0;
}

A bit of explanation:

It works by creating a "selection array" (v), where we place r selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v.

You can implement it if you note that for each level r you select a number from 1 to n.

In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance

#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>

using namespace std;

struct combinations
{
    typedef vector<int> combination_t;

    // initialize status
   combinations(int N, int R) :
       completed(N < 1 || R > N),
       generated(0),
       N(N), R(R)
   {
       for (int c = 1; c <= R; ++c)
           curr.push_back(c);
   }

   // true while there are more solutions
   bool completed;

   // count how many generated
   int generated;

   // get current and compute next combination
   combination_t next()
   {
       combination_t ret = curr;

       // find what to increment
       completed = true;
       for (int i = R - 1; i >= 0; --i)
           if (curr[i] < N - R + i + 1)
           {
               int j = curr[i] + 1;
               while (i <= R-1)
                   curr[i++] = j++;
               completed = false;
               ++generated;
               break;
           }

       return ret;
   }

private:

   int N, R;
   combination_t curr;
};

int main(int argc, char **argv)
{
    int N = argc >= 2 ? atoi(argv[1]) : 5;
    int R = argc >= 3 ? atoi(argv[2]) : 2;
    combinations cs(N, R);
    while (!cs.completed)
    {
        combinations::combination_t c = cs.next();
        copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
        cout << endl;
    }
    return cs.generated;
}

I have been working on this for some time now. Tough to get right, and I don't claim I do, but I'm happy with it so far. My code and several demos can be found at

• https://github.com/bauerca/drag-sort-listview

Its use is very similar to the TouchInterceptor (on which the code is based), although significant implementation changes have been made.

DragSortListView has smooth and predictable scrolling while dragging and shuffling items. Item shuffles are much more consistent with the position of the dragging/floating item. Heterogeneous-height list items are supported. Drag-scrolling is customizable (I demonstrate rapid drag scrolling through a long list---not that an application comes to mind). Headers/Footers are respected. etc.?? Take a look.

You have #include "fun.cpp" in mainfile.cpp so compiling with:

g++ -o hw1 mainfile.cpp

will work, however if you compile by linking these together like

g++ -g -std=c++11 -Wall -pedantic   -c -o fun.o fun.cpp
g++ -g -std=c++11 -Wall -pedantic   -c -o mainfile.o mainfile.cpp

As they mention above, adding #include "fun.hpp" will need to be done or it won't work. However, your case with the funct() function is slightly different than my problem.

I had this issue when doing a HW assignment and the autograder compiled by the lower bash recipe, yet locally it worked using the upper bash.

Find this useful solution

function get_duplicates( $array ) {
    return array_unique( array_diff_assoc( $array, array_unique( $array ) ) );
}

After that count result if greater than 0 than duplicates else unique.

As far as I know, this is the C++ Runtime Library. So it depends on the compiler you use to create your program (A new version will include some C++0x stuff, an older version will probably not for instance. It depends of the compiler and of its version).

If you use MinGW then you should use the libstdc++-6.dll found into the folder of this compiler. MinGW/bin folder should be the place to search for it on your computer.

If you copy this file in the same directory as your executable, it should be OK.

There is a new player in the field, offering advanced Navigation Charts that are using Canvas for super-smooth animations and performance:

https://zoomcharts.com/

Example of charts:

Documentation: https://zoomcharts.com/en/javascript-charts-library/charts-packages/pie-chart/

What is cool about this lib:

• Others slice can be expanded
• Pie offers drill down for hierarchical structures (see example)
• write your own data source controller easily, or provide simple json file
• export high res images out of box
• full touch support, works smoothly on iPad, iPhone, android, etc.

Charts are free for non-commercial use, commercial licenses and technical support available as well.

Also interactive Time charts and Net Charts are there for you to use.

Charts come with extensive API and Settings, so you can control every aspect of the charts.

When you use

this.getClass().getResource("myFile.ext")

getResource will try to find the resource relative to the package. If you use:

this.getClass().getResource("/myFile.ext")

getResource will treat it as an absolute path and simply call the classloader like you would have if you'd done.

this.getClass().getClassLoader().getResource("myFile.ext")

The reason you can't use a leading / in the ClassLoader path is because all ClassLoader paths are absolute and so / is not a valid first character in the path.

Also, here is how to calculate a 64-bit NSNumber initialized with the Unix epoch in milliseconds, in case that is how you want to store it in CoreData. I needed this for my app which interacts with a system that stores dates this way.

  + (NSNumber*) longUnixEpoch {
      return [NSNumber numberWithLongLong:[[NSDate date] timeIntervalSince1970] * 1000];
  }

To address one possible root of the actual issue, there is a chance you are sourcing a crlf file.

CRLF Example:

.env (crlf)

VARIABLE_A="abc"
VARIABLE_B="def"

run.sh

#!/bin/bash
source .env
echo "$VARIABLE_A"
echo "$VARIABLE_B"
echo "$VARIABLE_A $VARIABLE_B"

Returns:

abc
def
 def

If however you convert to LF:

.env (lf)

VARIABLE_A="abc"
VARIABLE_B="def"

run.sh

#!/bin/bash
source .env
echo "$VARIABLE_A"
echo "$VARIABLE_B"
echo "$VARIABLE_A $VARIABLE_B"

Returns:

abc
def
abc def

On which point does HTTPURLConnection try to establish a connection to the given URL?

On the port named in the URL if any, otherwise 80 for HTTP and 443 for HTTPS. I believe this is documented.

On which point can I know that I was able to successfully establish a connection?

When you call getInputStream() or getOutputStream() or getResponseCode() without getting an exception.

Are establishing a connection and sending the actual request done in one step/method call? What method is it?

No and none.

Can you explain the function of getOutputStream() and getInputStream() in layman's term?

Either of them first connects if necessary, then returns the required stream.

I notice that when the server I'm trying to connect to is down, I get an Exception at getOutputStream(). Does it mean that HTTPURLConnection will only start to establish a connection when I invoke getOutputStream()? How about the getInputStream()? Since I'm only able to get the response at getInputStream(), then does it mean that I didn't send any request at getOutputStream() yet but simply establishes a connection? Do HttpURLConnection go back to the server to request for response when I invoke getInputStream()?

See above.

Am I correct to say that openConnection() simply creates a new connection object but does not establish any connection yet?

Yes.

How can I measure the read overhead and connect overhead?

Connect: take the time getInputStream() or getOutputStream() takes to return, whichever you call first. Read: time from starting first read to getting the EOS.

Use the rename() function.

rename("user/image1.jpg", "user/del/image1.jpg");

Handy one liner to parse a CSV file into an array

$csv = array_map('str_getcsv', file('data.csv'));

Inside your function for the click action use

$( "#tabs" ).tabs({ active: # });

Where # is replaced by the tab index you want to select.

Try:

select id, game, min(point) from t
group by id 

>>> map(myList.__getitem__, (2,2,1,3))
('baz', 'baz', 'bar', 'quux')

You can also create your own List class which supports tuples as arguments to __getitem__ if you want to be able to do myList[(2,2,1,3)].

Reading CSV format description makes me feel that using 3rd party library would be less headache than writing it myself:

• http://en.wikipedia.org/wiki/Comma-separated_values

Wikipedia lists 10 or something known libraries:

• http://en.wikipedia.org/wiki/CSV_application_support

I compared libs listed using some kind of check list. OpenCSV turned out a winner to me (YMMV) with the following results:

+ maven

+ maven - release version   // had some cryptic issues at _Hudson_ with snapshot references => prefer to be on a safe side

+ code examples

+ open source   // as in "can hack myself if needed"

+ understandable javadoc   // as opposed to eg javadocs of _genjava gj-csv_

+ compact API   // YAGNI (note *flatpack* seems to have much richer API than OpenCSV)

- reference to specification used   // I really like it when people can explain what they're doing

- reference to _RFC 4180_ support   // would qualify as simplest form of specification to me

- releases changelog   // absence is quite a pity, given how simple it'd be to get with maven-changes-plugin   // _flatpack_, for comparison, has quite helpful changelog

+ bug tracking

+ active   // as in "can submit a bug and expect a fixed release soon"

+ positive feedback   // Recommended By 51 users at sourceforge (as of now)

MSK,

Have you tried setting a namespace declaration to your member variables like this? :

@XmlElement(required = true, namespace = "http://example.com/a")
protected String username;

@XmlElement(required = true, namespace = "http://example.com/a")
protected String password;

For our project, it solved namespace issues. We also had to create NameSpacePrefixMappers.

Below will list all the distinct data types of all the table in the provided schema name.

I realize this question is a bit dated and since it shows up on Google search for similar issue I thought I will expand a little bit more on top of @CowWarrior's answer. I was looking for somewhat similar solution, and after scouring through countless SO question/answers and Bootstrap documentations the solution was pretty simple. Again, this would be using inbuilt Bootstrap collapse class to show/hide divs and Bootstrap's "Collapse Event".

What I realized is that it is easy to do it using a Bootstrap Accordion, but most of the time even though the functionality required is "somewhat" similar to an Accordion, it's different in a way that one would want to show hide <div> based on, lets say, menu buttons on a navbar. Below is a simple solution to this. The anchor tags (<a>) could be navbar items and based on a collapse event the corresponding div will replace the existing div. It looks slightly sloppy in CodeSnippet, but it is pretty close to achieving the functionality-

All that the JavaScript does is makes all the other <div> hide using

$(".main-container.collapse").not($(this)).collapse('hide');

when the loaded <div> is displayed by checking the Collapse event shown.bs.collapse. Here's the Bootstrap documentation on Collapse Event.

Note: main-container is just a custom class.

Here it goes-

$(".main-container.collapse").on('shown.bs.collapse', function () {    _x000D_
//when a collapsed div is shown hide all other collapsible divs that are visible_x000D_
       $(".main-container.collapse").not($(this)).collapse('hide');_x000D_
});

<a href="#Bar" class="btn btn-default" data-toggle="collapse">Toggle Bar</a>_x000D_
_x000D_
<div id="Bar" class="main-container collapse in">_x000D_
    This div (#Bar) is shown by default and can toggle_x000D_
</div>_x000D_
<div id="Foo" class="main-container collapse">_x000D_
    This div (#Foo) is hidden by default_x000D_
</div>

If the issue is a missing intermediate certificate, you can enable Oracle JRE to automatically download the missing intermediate certificate as explained in this answer.

Just set the Java system property -Dcom.sun.security.enableAIAcaIssuers=true

For this to work the server's certificate must provide the URI to the intermediate certificate (the certificate's issuer). As far as I can tell, this is what browsers do as well and should be just as secure - I'm not a security expert though.

Edit: If I recall correctly, this seems to work at least with Java 8 and is documented here for Java 9.

I'd recommend using the java.text package:

double money = 100.1;
NumberFormat formatter = NumberFormat.getCurrencyInstance();
String moneyString = formatter.format(money);
System.out.println(moneyString);

This has the added benefit of being locale specific.

But, if you must, truncate the String you get back if it's a whole dollar:

if (moneyString.endsWith(".00")) {
    int centsIndex = moneyString.lastIndexOf(".00");
    if (centsIndex != -1) {
        moneyString = moneyString.substring(1, centsIndex);
    }
}

Heres the method I used in my logging library: https://github.com/goktugyil/QorumLogs

This method fills html forms inside Google Forms.

    var url = NSURL(string: urlstring)

    var request = NSMutableURLRequest(URL: url!)
    request.HTTPMethod = "POST"
    request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
    request.HTTPBody = postData.dataUsingEncoding(NSUTF8StringEncoding)
    var connection = NSURLConnection(request: request, delegate: nil, startImmediately: true)

You have the right idea, as documentation shows:

http://docs.jquery.com/CSS/css#namevalue

Are you sure you're correctly identify this with class or id?

For example, if your class is myElementClass

$('.myElementClass').css('text-align','center');

Also, I haven't worked with Firebug in a while, but are you looking at the dom and not the html? Your source isn't changed by javascript, but the dom is. Look in the dom tab and see if the change was applied.

Change the position attribute to fixed instead of absolute.

In my case, the problem was with a scatterplot of a dataframe X[]:

ax.scatter(X[:,0],X[:,1],c=colors,    
       cmap=CMAP, edgecolor='k', s=40)  #c=y[:,0],

#ValueError: setting an array element with a sequence.
#Fix with .toarray():
colors = 'br'
y = label_binarize(y, classes=['Irrelevant','Relevant'])
ax.scatter(X[:,0].toarray(),X[:,1].toarray(),c=colors,   
       cmap=CMAP, edgecolor='k', s=40)

dynamic data = List<x> val;  
List<y> val2 = ((IEnumerable)data).Cast<y>().ToList();

Generally i prefer the lambda syntax with LINQ, but Join is one example where i prefer the query syntax - purely for readability.

Nonetheless, here is the equivalent of your above query (i think, untested):

var query = db.Categories         // source
   .Join(db.CategoryMaps,         // target
      c => c.CategoryId,          // FK
      cm => cm.ChildCategoryId,   // PK
      (c, cm) => new { Category = c, CategoryMaps = cm }) // project result
   .Select(x => x.Category);  // select result

You might have to fiddle with the projection depending on what you want to return, but that's the jist of it.

there are some solution to solve this issue : 1 ) run your command prompt as "administrator".

if first solution doesn't solve your problem try this one :

2 ) open a command prompt as administrator paste following line of code and hit enter :

npm install --global --production windows-build-tools

It is because you are in a try statement. Since there could be an error, sum might not get initialized, so put your return statement in the finally block, that way it will for sure be returned.

Make sure that you initialize sum outside the try/catch/finally so that it is in scope.

I know this question is resolved but, for the benefit of anyone else reading it; if you have all of the types involved as strings, you could do this as a one liner:

IYourInterface o = (Activator.CreateInstance(Type.GetType("Namespace.TaskA`1[OtherNamespace.TypeParam]") as IYourInterface);

Whenever I've done this kind of thing, I've had an interface which I wanted subsequent code to utilise, so I've casted the created instance to an interface.

There doesn't appear to be an external way to hack the behaviour of the executables.

You could modify the Chrome(ium) executables as this information is obviously compiled in. That approach brings a lot of problems with support and automatic upgrades so you probably want to avoid doing that. You also need to understand how to make the changes to the binaries which is not something most people can pick up in a few days.

If you compile your own browser you are creating a support issue for yourself as you are stuck with a specific revision. If you want to get new features and bug fixes you will have to recompile. All of this involves tracking Chrome development for bugs and build breakages - not something that a web developer should have to do.

I'd follow @BenSwayne's advice for now, but it might be worth thinking about doing some of the work outside of the client (the web browser) and putting it in a background process running on the same or different machines. This process can handle many more connections and you are just responsible for getting the data back from it. Since it is local(ish) you'll get results back quickly even with minimal connections.

If there are multiple sheets this is lost in the conversion but you could loop over the number of sheets and save each one as csv.

There are a few characters that are dissallowed in XML documents, even when you encapsulate data in CDATA-blocks.

If you generated the document you will need to entity encode it or strip it out. If you have an errorneous document, you should strip away these characters before trying to parse it.

See dolmens answer in this thread: Invalid Characters in XML

Where he links to this article: http://www.w3.org/TR/xml/#charsets

Basically, all characters below 0x20 is disallowed, except 0x9 (TAB), 0xA (CR?), 0xD (LF?)

I suppose that calling Array.prototype functions on instances of HTMLCollection is a much better option than converting collections to arrays (e.g.,[...collection] or Array.from(collection)), because in the latter case a collection is unnecessarily implicitly iterated and a new array object is created, and this eats up additional resources. Array.prototype iterating functions can be safely called upon objects with consecutive numeric keys starting from [0] and a length property with a valid number value of such keys' quantity (including, e.g., instances of HTMLCollection and FileList), so it's a reliable way. Also, if there is a frequent need in such operations, an empty array [] can be used for quick access to Array.prototype functions; or a shortcut for Array.prototype can be created instead. A runnable example:

const _ = Array.prototype;
const collection = document.getElementById('ol').children;
alert(_.reduce.call(collection, (acc, { textContent }, i) => {
  return acc += `${i+1}) ${textContent}` + '\n';
}, ''));

<ol id="ol">

Python includes the round() function which lets you specify the number of digits you want. From the documentation:

round(x[, n])

Return the floating point value x rounded to n digits after the decimal point. If n is omitted, it defaults to zero. The result is a floating point number. Values are rounded to the closest multiple of 10 to the power minus n; if two multiples are equally close, rounding is done away from 0 (so. for example, round(0.5) is 1.0 and round(-0.5) is -1.0).

So you would want to use round(x, 2) to do normal rounding. To ensure that the number is always rounded up you would need to use the ceil(x) function. Similarly, to round down use floor(x).

Nowadays, people use DESC instead of DESCRIPTION. For example:- DESC users;

I'm in the process of making a nicer demo as well as cleaning up some of these services into a usable module, but here's what I've come up with. This is a complex process to work around some caveats, so hang in there. You'll need to break this down into several pieces.

Take a look at this plunk.

First, you need a service to store the user's identity. I call this principal. It can be checked to see if the user is logged in, and upon request, it can resolve an object that represents the essential information about the user's identity. This can be whatever you need, but the essentials would be a display name, a username, possibly an email, and the roles a user belongs to (if this applies to your app). Principal also has methods to do role checks.

.factory('principal', ['$q', '$http', '$timeout',
  function($q, $http, $timeout) {
    var _identity = undefined,
      _authenticated = false;

    return {
      isIdentityResolved: function() {
        return angular.isDefined(_identity);
      },
      isAuthenticated: function() {
        return _authenticated;
      },
      isInRole: function(role) {
        if (!_authenticated || !_identity.roles) return false;

        return _identity.roles.indexOf(role) != -1;
      },
      isInAnyRole: function(roles) {
        if (!_authenticated || !_identity.roles) return false;

        for (var i = 0; i < roles.length; i++) {
          if (this.isInRole(roles[i])) return true;
        }

        return false;
      },
      authenticate: function(identity) {
        _identity = identity;
        _authenticated = identity != null;
      },
      identity: function(force) {
        var deferred = $q.defer();

        if (force === true) _identity = undefined;

        // check and see if we have retrieved the 
        // identity data from the server. if we have, 
        // reuse it by immediately resolving
        if (angular.isDefined(_identity)) {
          deferred.resolve(_identity);

          return deferred.promise;
        }

        // otherwise, retrieve the identity data from the
        // server, update the identity object, and then 
        // resolve.
        //           $http.get('/svc/account/identity', 
        //                     { ignoreErrors: true })
        //                .success(function(data) {
        //                    _identity = data;
        //                    _authenticated = true;
        //                    deferred.resolve(_identity);
        //                })
        //                .error(function () {
        //                    _identity = null;
        //                    _authenticated = false;
        //                    deferred.resolve(_identity);
        //                });

        // for the sake of the demo, fake the lookup
        // by using a timeout to create a valid
        // fake identity. in reality,  you'll want 
        // something more like the $http request
        // commented out above. in this example, we fake 
        // looking up to find the user is
        // not logged in
        var self = this;
        $timeout(function() {
          self.authenticate(null);
          deferred.resolve(_identity);
        }, 1000);

        return deferred.promise;
      }
    };
  }
])

Second, you need a service that checks the state the user wants to go to, makes sure they're logged in (if necessary; not necessary for signin, password reset, etc.), and then does a role check (if your app needs this). If they are not authenticated, send them to the sign-in page. If they are authenticated, but fail a role check, send them to an access denied page. I call this service authorization.

.factory('authorization', ['$rootScope', '$state', 'principal',
  function($rootScope, $state, principal) {
    return {
      authorize: function() {
        return principal.identity()
          .then(function() {
            var isAuthenticated = principal.isAuthenticated();

            if ($rootScope.toState.data.roles
                && $rootScope.toState
                             .data.roles.length > 0 
                && !principal.isInAnyRole(
                   $rootScope.toState.data.roles))
            {
              if (isAuthenticated) {
                  // user is signed in but not
                  // authorized for desired state
                  $state.go('accessdenied');
              } else {
                // user is not authenticated. Stow
                // the state they wanted before you
                // send them to the sign-in state, so
                // you can return them when you're done
                $rootScope.returnToState
                    = $rootScope.toState;
                $rootScope.returnToStateParams
                    = $rootScope.toStateParams;

                // now, send them to the signin state
                // so they can log in
                $state.go('signin');
              }
            }
          });
      }
    };
  }
])

Now all you need to do is listen in on ui-router's $stateChangeStart. This gives you a chance to examine the current state, the state they want to go to, and insert your authorization check. If it fails, you can cancel the route transition, or change to a different route.

.run(['$rootScope', '$state', '$stateParams', 
      'authorization', 'principal',
    function($rootScope, $state, $stateParams, 
             authorization, principal)
{
      $rootScope.$on('$stateChangeStart', 
          function(event, toState, toStateParams)
      {
        // track the state the user wants to go to; 
        // authorization service needs this
        $rootScope.toState = toState;
        $rootScope.toStateParams = toStateParams;
        // if the principal is resolved, do an 
        // authorization check immediately. otherwise,
        // it'll be done when the state it resolved.
        if (principal.isIdentityResolved()) 
            authorization.authorize();
      });
    }
  ]);

The tricky part about tracking a user's identity is looking it up if you've already authenticated (say, you're visiting the page after a previous session, and saved an auth token in a cookie, or maybe you hard refreshed a page, or dropped onto a URL from a link). Because of the way ui-router works, you need to do your identity resolve once, before your auth checks. You can do this using the resolve option in your state config. I have one parent state for the site that all states inherit from, which forces the principal to be resolved before anything else happens.

$stateProvider.state('site', {
  'abstract': true,
  resolve: {
    authorize: ['authorization',
      function(authorization) {
        return authorization.authorize();
      }
    ]
  },
  template: '<div ui-view />'
})

There's another problem here... resolve only gets called once. Once your promise for identity lookup completes, it won't run the resolve delegate again. So we have to do your auth checks in two places: once pursuant to your identity promise resolving in resolve, which covers the first time your app loads, and once in $stateChangeStart if the resolution has been done, which covers any time you navigate around states.

OK, so what have we done so far?

1. We check to see when the app loads if the user is logged in.
2. We track info about the logged in user.
3. We redirect them to sign in state for states that require the user to be logged in.
4. We redirect them to an access denied state if they do not have authorization to access it.
5. We have a mechanism to redirect users back to the original state they requested, if we needed them to log in.
6. We can sign a user out (needs to be wired up in concert with any client or server code that manages your auth ticket).
7. We don't need to send users back to the sign-in page every time they reload their browser or drop on a link.

Where do we go from here? Well, you can organize your states into regions that require sign in. You can require authenticated/authorized users by adding data with roles to these states (or a parent of them, if you want to use inheritance). Here, we restrict a resource to Admins:

.state('restricted', {
    parent: 'site',
    url: '/restricted',
    data: {
      roles: ['Admin']
    },
    views: {
      'content@': {
        templateUrl: 'restricted.html'
      }
    }
  })

Now you can control state-by-state what users can access a route. Any other concerns? Maybe varying only part of a view based on whether or not they are logged in? No problem. Use the principal.isAuthenticated() or even principal.isInRole() with any of the numerous ways you can conditionally display a template or an element.

First, inject principal into a controller or whatever, and stick it to the scope so you can use it easily in your view:

.scope('HomeCtrl', ['$scope', 'principal', 
    function($scope, principal)
{
  $scope.principal = principal;
});

Show or hide an element:

<div ng-show="principal.isAuthenticated()">
   I'm logged in
</div>
<div ng-hide="principal.isAuthenticated()">
  I'm not logged in
</div>

Etc., so on, so forth. Anyways, in your example app, you would have a state for home page that would let unauthenticated users drop by. They could have links to the sign-in or sign-up states, or have those forms built into that page. Whatever suits you.

The dashboard pages could all inherit from a state that requires the users to be logged in and, say, be a User role member. All the authorization stuff we've discussed would flow from there.

I know this is old, but I was having trouble too. For Spring 3 using Maven and Eclipse, I needed to put the log4j.xml in src/test/resources for the Unit test to log properly. Placing in in the root of the test did not work for me. Hopefully this helps others.

Use ToString("X4").

The 4 means that the string will be 4 digits long.

In addition, since info locals does not display the arguments to the function you're in, use

(gdb) info args

For example:

int main(int argc, char *argv[]) {
    argc = 6*7;    //Break here.
    return 0;
}

argc and argv won't be shown by info locals. The message will be "No locals."

Reference: info locals command.

If the table is already created in the database, then you can add a unique constraint later on by using this SQL query:

ALTER TABLE dbo.User
  ADD CONSTRAINT ucCodes UNIQUE (fcode, scode, dcode)

I can handle this way:

select to_number(to_char(sysdate,'MI')) - to_number(to_char(*YOUR_DATA_VALUE*,'MI')),max(exp_time)  from ...

Or if you want to the hour just change the MI;

select to_number(to_char(sysdate,'HH24')) - to_number(to_char(*YOUR_DATA_VALUE*,'HH24')),max(exp_time)  from ...

the others don't work for me. Good luck.

Herb Sutter has an excellent article on string formatting. I recommend reading it. I've linked it before on SO.

Judging by the documentation for date/time functions, you should be able to do something like:

SELECT * FROM FOO
WHERE MY_DATE_FIELD >= NOW() - INTERVAL 1 DAY

In C++, objects allocated on the stack (using Object object; statement within a block) will only live within the scope they are declared in. When the block of code finishes execution, the object declared are destroyed. Whereas if you allocate memory on heap, using Object* obj = new Object(), they continue to live in heap until you call delete obj.

I would create an object on heap when I like to use the object not only in the block of code which declared/allocated it.

<< is a binary shift, shifting 1 to the left 8 places.

4'b0001 << 1 => 4'b0010

>> is a binary right shift adding 0's to the MSB.
>>> is a signed shift which maintains the value of the MSB if the left input is signed.

4'sb1011 >>  1 => 0101
4'sb1011 >>> 1 => 1101

Three ways to indicate left operand is signed:

module shift;
  logic        [3:0] test1 = 4'b1000;
  logic signed [3:0] test2 = 4'b1000;

  initial begin
    $display("%b", $signed(test1) >>> 1 ); //Explicitly set as signed
    $display("%b", test2          >>> 1 ); //Declared as signed type
    $display("%b", 4'sb1000       >>> 1 ); //Signed constant
    $finish;
  end
endmodule

Unfortunately, you have a malformed url query string, so a regex technique is most appropriate. See what I mean.

There is no need for capture groups. Just match id= then forget those characters with \K, then isolate the following one or more digital characters.

Code (Demo)

$str = 'producturl.php?id=736375493?=tm';
echo preg_match('~id=\K\d+~', $str, $out) ? $out[0] : 'no match';

Output:

736375493

Using ASP.NET, just simply do this:

<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>Automatic Resize TextBox</title>
        <script type="text/javascript">
            function setHeight(txtarea) {
                txtarea.style.height = txtdesc.scrollHeight + "px";
            }
        </script>
    </head>

    <body>
        <form id="form1" runat="server">
            <asp:TextBox ID="txtarea" runat= "server" TextMode="MultiLine"  onkeyup="setHeight(this);" onkeydown="setHeight(this);" />
        </form>
    </body>
</html>

Just center the div in HTML:

  #test {
     width: 100px;
     height:100px;
     margin: 0px auto;
     border: 1px solid red;
   }


<div id="test">
   <canvas width="100" height="100"></canvas>
</div>

Just change the height and width to whatever and you've got a centered div

just call startForeground method immediately after Service or IntentService is Created. like this:

import android.app.Notification;
public class AuthenticationService extends Service {

    @Override
    public void onCreate() {
        super.onCreate();
        startForeground(1,new Notification());
    }
}

You can always use material button if you are using Material App as your main Widget.

Padding(
  padding: EdgeInsets.symmetric(vertical: 16.0),
  child: Material(
    borderRadius: BorderRadius.circular(30.0),//Set this up for rounding corners.
    shadowColor: Colors.lightBlueAccent.shade100,
    child: MaterialButton(
      minWidth: 200.0,
      height: 42.0,
      onPressed: (){//Actions here//},
      color: Colors.lightBlueAccent,
      child: Text('Log in', style: TextStyle(color: Colors.white),),
    ),
  ),
)

$http_name_of_the_header_key

i.e if you have origin = domain.com in header, you can use $http_origin to get "domain.com"

In nginx does support arbitrary request header field. In the above example last part of a variable name is the field name converted to lower case with dashes replaced by underscores

Reference doc here: http://nginx.org/en/docs/http/ngx_http_core_module.html#var_http_

For your example the variable would be $http_my_custom_header.

Try this:

explode(PHP_EOF, $lines);

I made something like that:

$('#image-file').on('change', function() {
 var numb = $(this)[0].files[0].size/1024/1024;
numb = numb.toFixed(2);
if(numb > 2){
alert('to big, maximum is 2MiB. You file size is: ' + numb +' MiB');
} else {
alert('it okey, your file has ' + numb + 'MiB')
}
        });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>

I haven't done Xcode in a bit, but I recommend that you disable "Zerolink" and "Load Symbols Lazily"; that will fix most problems. Zerolink is an abomination anyway.

The general approach to write to any stream (not only MemoryStream) is to use BinaryWriter:

static void Write(Stream s, Byte[] bytes)
{
    using (var writer = new BinaryWriter(s))
    {
        writer.Write(bytes);
    }
}

When you are working with fixed or absolute values, it's good idea to set top or bottom and left or right (or combination of them) properties.

Also don't set the height of main element (let browser set the height of it with setting top and bottom properties).

.header{
    position: fixed;
    background-color: #f00;
    height: 100px;
    top: 0;
    left: 0;
    right: 0;
}
.main{
    background-color: #ff0;
    position: fixed;
    bottom: 120px;
    left: 0;
    right: 0;
    top: 100px;
    overflow: auto;
}
.footer{
    position: fixed;
    bottom: 0;
    background-color: #f0f;
    height: 120px;
    bottom: 0;
    left: 0;
    right: 0;
}

you can use this code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;

                                                        return u;
                                                     }, (key,g)=>g.ToList())
                         .ToList();

If you don't want to change the original data, you should add some method (kind of clone and modify) to your class like this:

public class Customer {
  public int ID { get; set; }
  public string Name { get; set; }
  public int GroupID { get; set; }
  public Customer CloneWithNamePrepend(string prepend){
    return new Customer(){
          ID = this.ID,
          Name = prepend + this.Name,
          GroupID = this.GroupID
     };
  }
}    
//Then
var groupedCustomerList = CustomerList
                         .GroupBy(u => u.GroupID, u=>u.CloneWithNamePrepend("User"), (key,g)=>g.ToList())
                         .ToList();

I think you may want to display the Customer differently without modifying the original data. If so you should design your class Customer differently, like this:

public class Customer {
  public int ID { get; set; }
  public string Name { get; set; }
  public int GroupID { get; set; }
  public string Prefix {get;set;}
  public string FullName {
    get { return Prefix + Name;}
  }            
}
//then to display the fullname, just get the customer.FullName; 
//You can also try adding some override of ToString() to your class

var groupedCustomerList = CustomerList
                         .GroupBy(u => {u.Prefix="User", return u.GroupID;} , (key,g)=>g.ToList())
                         .ToList();

This code works for me: check this link
This is my code when i stop and start service in activity

case R.id.buttonStart:
  Log.d(TAG, "onClick: starting srvice");
  startService(new Intent(this, MyService.class));
  break;
case R.id.buttonStop:
  Log.d(TAG, "onClick: stopping srvice");
  stopService(new Intent(this, MyService.class));
  break;
}
}
 }

And in service class:

  @Override
public void onCreate() {
    Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
    Log.d(TAG, "onCreate");

    player = MediaPlayer.create(this, R.raw.braincandy);
    player.setLooping(false); // Set looping
}

@Override
public void onDestroy() {
    Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
    Log.d(TAG, "onDestroy");
    player.stop();
}

HAPPY CODING!

Faced the same problem. Probably it could be a solution:

<select id="select-1">
    <option>One</option>
    <option>Two</option>
    <option>Three</option>
</select>
<label for="select-1"></label>

#select-1 {
    ...
}

#select-1 + label:after {
    ...
}

Well, getting full path is not possible but we can have a temporary path.

Try This:

It'll give you a temporary path not the accurate path, you can use this script if you want to show selected images as in this jsfiddle example(Try it by selectng images as well as other files):-

JSFIDDLE

Here is the code :-

HTML:-

<input type="file" id="i_file" value=""> 
<input type="button" id="i_submit" value="Submit">
    <br>
<img src="" width="200" style="display:none;" />
        <br>
<div id="disp_tmp_path"></div>

JS:-

$('#i_file').change( function(event) {
var tmppath = URL.createObjectURL(event.target.files[0]);
    $("img").fadeIn("fast").attr('src',URL.createObjectURL(event.target.files[0]));

    $("#disp_tmp_path").html("Temporary Path(Copy it and try pasting it in browser address bar) --> <strong>["+tmppath+"]</strong>");
});

Its not exactly what you were looking for, but may be it can help you somewhere.

How about this?

$( document ).ready(function() {
    $('#fixed').width($('#wrap').width());
});

By using jquery you can set any kind of width :)

EDIT: As stated by dream in the comments, using JQuery just for this effect is pointless and even counter productive. I made this example for people who use JQuery for other stuff on their pages and consider using it for this part also. I apologize for any inconvenience my answer caused.

The Angular microsyntax lets you configure a directive in a compact, friendly string. The microsyntax parser translates that string into attributes on the <ng-template>. The let keyword declares a template input variable that you reference within the template.

I believe the original question said:

a character belongs to a list/array of invalid characters

and not:

belongs to a null-terminated string

which, if it did, then strchr would indeed be the most suitable answer. If, however, there is no null termination to an array of chars or if the chars are in a list structure, then you will need to either create a null-terminated string and use strchr or manually iterate over the elements in the collection, checking each in turn. If the collection is small, then a linear search will be fine. A large collection may need a more suitable structure to improve the search times - a sorted array or a balanced binary tree for example.

Pick whatever works best for you situation.

If you want your integers to be bound between two integers (i.e. start with something other than 1), you can use something like this:

with bnd as (select 4 lo, 9 hi from dual)
select (select lo from bnd) - 1 + level r
from dual
connect by level <= (select hi-lo from bnd);

It gives:

4
5
6
7
8

I've also found it useful to access object attributes where the attribute names vary by some iterator. For example, I have used the pattern below for a set of time periods: hour, day, month.

$periods=array('hour', 'day', 'month');
foreach ($periods as $period)
{
    $this->{'value_'.$period}=1;
}

This same pattern can also be used to access class methods. Just build up the method name in the same manner, using strings and string variables.

You could easily argue to just use an array for the value storage by period. If this application were PHP only, I would agree. I use this pattern when the class attributes map to fields in a database table. While it is possible to store arrays in a database using serialization, it is inefficient, and pointless if the individual fields must be indexed. I often add an array of the field names, keyed by the iterator, for the best of both worlds.

class timevalues
{
                             // Database table values:
    public $value_hour;      // maps to values.value_hour
    public $value_day;       // maps to values.value_day
    public $value_month;     // maps to values.value_month
    public $values=array();

    public function __construct()
    {
        $this->value_hour=0;
        $this->value_day=0;
        $this->value_month=0;
        $this->values=array(
            'hour'=>$this->value_hour,
            'day'=>$this->value_day,
            'month'=>$this->value_month,
        );
    }
}

From the documentation. The develop will not install the package but it will create a .egg-link in the deployment directory back to the project source code directory.

So it's like installing but instead of copying to the site-packages it adds a symbolic link (the .egg-link acts as a multiplatform symbolic link).

That way you can edit the source code and see the changes directly without having to reinstall every time that you make a little change. This is useful when you are the developer of that project hence the name develop. If you are just installing someone else's package you should use install

If there are any proxy networks are configured remove them till plugins are installed

@ user2310334 I just tried this, a VERY basic example:

HTML file

<!DOCTYPE html>
<html lang="en" ng-app="app">

<head>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.6/angular.min.js" type="text/javascript"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.6/angular-route.min.js" type="text/javascript"></script>
    <script src="./app.js" type="text/javascript"></script>
</head>

<body>
    <div ng-controller="MailDetailCtrl">
    </div>
</body>
</html>

The javascript file:

var myApp= angular.module('app', ['ngRoute']);

myApp.factory('mailService' , function () {
return {
    getData : function(){
      var employees = [{name: 'John Doe', id: '1'},
        {name: 'Mary Homes', id: '2'},
        {name: 'Chris Karl', id: '3'}
      ];

      return employees;
    }
  };

});


myApp.controller('MailDetailCtrl',['$scope', 'mailService', function($scope, mailService) {
  alert(mailService.getData()[0].name);
}]);

And it works. Try it.

If you want to sort by something like creation date you probably need to use DirectoryInfo.GetFiles and then sort the resulting array using a suitable Predicate.

@selectField1 AS bit
@selectField2 AS bit

SELECT
CASE 
    WHEN @selectField1 THEN Field1
    WHEN @selectField2 THEN Field2
    ELSE someDefaultField
END
FROM Table

Is this what you're looking for?

Using the standard mysql.createPool(), connections are lazily created by the pool. If you configure the pool to allow up to 100 connections, but only ever use 5 simultaneously, only 5 connections will be made. However if you configure it for 500 connections and use all 500 they will remain open for the durations of the process, even if they are idle!

This means if your MySQL Server max_connections is 510 your system will only have 10 mySQL connections available until your MySQL Server closes them (depends on what you have set your wait_timeout to) or your application closes! The only way to free them up is to manually close the connections via the pool instance or close the pool.

mysql-connection-pool-manager module was created to fix this issue and automatically scale the number of connections dependant on the load. Inactive connections are closed and idle connection pools are eventually closed if there has not been any activity.

    // Load modules
const PoolManager = require('mysql-connection-pool-manager');

// Options
const options = {
  ...example settings
}

// Initialising the instance
const mySQL = PoolManager(options);

// Accessing mySQL directly
var connection = mySQL.raw.createConnection({
  host     : 'localhost',
  user     : 'me',
  password : 'secret',
  database : 'my_db'
});

// Initialising connection
connection.connect();

// Performing query
connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
  if (error) throw error;
  console.log('The solution is: ', results[0].solution);
});

// Ending connection
connection.end();

I prefer the VBA-solution for professional solutions.

With the replace-procedure part in the question search and replace WHOLE WORDS ONLY, I use the following VBA-procedure:

''
' Evaluate Formula-Text in Excel
'
Function wm_Eval(myFormula As String, ParamArray variablesAndValues() As Variant) As Variant
    Dim i As Long

    '
    ' replace strings by values
    '
    For i = LBound(variablesAndValues) To UBound(variablesAndValues) Step 2
        myFormula = RegExpReplaceWord(myFormula, variablesAndValues(i), variablesAndValues(i + 1))
    Next

    '
    ' internationalisation
    '
    myFormula = Replace(myFormula, Application.ThousandsSeparator, "")
    myFormula = Replace(myFormula, Application.DecimalSeparator, ".")
    myFormula = Replace(myFormula, Application.International(xlListSeparator), ",")

    '
    ' return value
    '
    wm_Eval = Application.Evaluate(myFormula)
End Function


''
' Replace Whole Word

' Purpose   : replace [strFind] with [strReplace] in [strSource]

Public Function RegExpReplaceWord(ByVal strSource As String, _
ByVal strFind As String, _
ByVal strReplace As String) As String

    ' early binding requires reference to Microsoft VBScript
    ' Regular Expressions:

    Dim re As Object
    Set re = CreateObject("VBScript.RegExp")

    re.Global = True
    're.IgnoreCase = True ' <-- case insensitve
    re.Pattern = "\b" & strFind & "\b"
    RegExpReplaceWord = re.Replace(strSource, strReplace)
    Set re = Nothing

Usage of the procedure in an excel sheet looks like:

For Official information:

A simple Example:

On any Element you have to add an attribute ref with a unique value

<input ref="foo" type="text" >

To target that elemet use this.$refs.foo

this.$refs.foo.focus(); // it will focus the input having ref="foo"

Puedes agregar una columna con tipo de dato distinto , luego copiar los datos y eliminar la columna anterior

TB.Columns.Add("columna1", GetType(Integer))    
TB.Select("id=id").ToList().ForEach(Sub(row) row("columna1") = row("columna2"))    
TB.Columns.Remove("columna2")

The new version has changed.. for the latest version use the code below:

$('#UpToDate').datetimepicker({
        format:'MMMM DD, YYYY',
        maxDate:moment(),
        defaultDate:moment()            
    }).on('dp.change',function(e){
        console.log(e);
    });

Well, the first interpretation is correct. However, your reasoning about the "signed semantics" in this context is wrong.

Again, your first interpretation is correct. Unsigned arithmetic follow the rules of modulo arithmetic, meaning that 0x0000 - 0x0001 evaluates to 0xFFFF for 32-bit unsigned types.

However, the second interpretation (the one based on "signed semantics") is also required to produce the same result. I.e. even if you evaluate 0 - 1 in the domain of signed type and obtain -1 as the intermediate result, this -1 is still required to produce 0xFFFF when later it gets converted to unsigned type. Even if some platform uses an exotic representation for signed integers (1's complement, signed magnitude), this platform is still required to apply rules of modulo arithmetic when converting signed integer values to unsigned ones.

For example, this evaluation

signed int a = 0, b = 1;
unsigned int c = a - b;

is still guaranteed to produce UINT_MAX in c, even if the platform is using an exotic representation for signed integers.

Try going to "Manage Jenkins"->"Manage Users" go to the specific user, edit his/her configuration "My Views section" default view.

Some times this error is a result of two ng-app directives specified in the html. In my case by mistake I had specified ng-app in my html tag and ng-app="myApp" in the body tag like this:

<html ng-app>
  <body ng-app="myApp"></body>
</html>

Well, WelcomeMessage is just a variable name for message (actual model with data). Basically, you are binding the model with the welcomePage here. The Model (message) will be available in welcomePage.jsp as WelcomeMessage. Here is a simpler example:

ModelAndView("hello","myVar", "Hello World!");

In this case, my model is a simple string (In applications this will be a POJO with data fetched for DB or other sources.). I am assigning it to myVar and my view is hello.jsp. Now, myVar is available for me in hello.jsp and I can use it for display.

In the view, you can access the data though:

${myVar}

Similarly, You will be able to access the model through WelcomeMessage variable.

I’ve been using ng cli lately, and it was really tough to find a good way to structure my code.

The most efficient one I've seen so far comes from mrholek repository (https://github.com/mrholek/CoreUI-Angular).

This folder structure allows you to keep your root project clean and structure your components, it avoids redundant (sometimes useless) naming convention of the official Style Guide.

Also it’s, this structure is useful to group import when it’s needed and avoid having 30 lines of import for a single file.

I had the same issue with numeral, a JS library. The fix was to install the typings again with this command:

npm install --save @types/numeral

You can't.

Although the SQL-92 syntax to add a foreign key to your table would be as follows:

ALTER TABLE child ADD CONSTRAINT fk_child_parent
                  FOREIGN KEY (parent_id) 
                  REFERENCES parent(id);

SQLite doesn't support the ADD CONSTRAINT variant of the ALTER TABLE command (sqlite.org: SQL Features That SQLite Does Not Implement).

Therefore, the only way to add a foreign key in sqlite 3.6.1 is during CREATE TABLE as follows:

CREATE TABLE child ( 
    id           INTEGER PRIMARY KEY, 
    parent_id    INTEGER, 
    description  TEXT,
    FOREIGN KEY (parent_id) REFERENCES parent(id)
);

Unfortunately you will have to save the existing data to a temporary table, drop the old table, create the new table with the FK constraint, then copy the data back in from the temporary table. (sqlite.org - FAQ: Q11)
