If you want to use recode recursively, and filter for type, try this:

find . -name "*.html" -exec recode L1..UTF8 {} \;

PHP 7.2

iconv('UTF-8', 'ASCII//TRANSLIT', 'é@ùµ$`à');
// "e@uu$`a"

iconv('UTF-8', 'ASCII//IGNORE', 'é@ùµ$`à');
// "@$`"

iconv('UTF-8', 'ASCII//TRANSLIT//IGNORE', 'é@ùµ$`à');
// "e@uu$`a"

PHP 7.4

iconv('UTF-8', 'ASCII//TRANSLIT', 'é@ùµ$`à');
// PHP Notice:  iconv(): Detected an illegal character

iconv('UTF-8', 'ASCII//IGNORE', 'é@ùµ$`à');
// "@$`"

iconv('UTF-8', 'ASCII//TRANSLIT//IGNORE', 'é@ùµ$`à');
// "e@u$`a"

iconv('UTF-8', 'ASCII//TRANSLIT//IGNORE', Transliterator::create('Any-Latin; NFD; [:Nonspacing Mark:] Remove; NFC')->transliterate('é@ùµ$`à'))
// "e@uu$`a" -> same as PHP 7.2

I can't reproduce your problem. I get the expected result.

How exactly are you using mb_detect_encoding() to verify your string is in fact UTF-8?

If I simply call mb_detect_encoding($input) on both a UTF-8 and ISO-8859-1 encoded version of your string, both of them return "UTF-8", so that function isn't particularly reliable.

iconv() gives me a PHP "notice" when it gets the wrongly encoded string and only echoes "F", but that might just be because of different PHP/iconv settings/versions (?).

I suggest to you try calling mb_check_encoding($input, "utf-8") first to verify that your string really is UTF-8. I think it probably isn't.

Here's a script that will find all files matching a pattern you pass it, and then converting them from their current file encoding to UTF-8. If the encoding is US ASCII, then it will still show as US ASCII, since that is a subset of UTF-8.

#!/usr/bin/env bash
find . -name "${1}" |
    while read line;
    do
        echo "***************************"
        echo "Converting ${line}"

        encoding=$(file -b --mime-encoding ${line})
        echo "Found Encoding: ${encoding}"

        iconv -f "${encoding}" -t "utf-8" ${line} -o ${line}.tmp
        mv ${line}.tmp ${line}
    done

Try this -->

 new DzieckoAndOpiekun(
                         p.Imie,
                         p.Nazwisko,
                         p.Opiekun.Imie,
                         p.Opiekun.Nazwisko).ToList()

The expression len(l) is evaluated only one time, at the moment the range() builtin is evaluated. The range object constructed at that time does not change; it can't possibly know anything about the object l.

P.S. l is a lousy name for a value! It looks like the numeral 1, or the capital letter I.

I use this, it works fine.

from django.utils import simplejson
from django.http import HttpResponse

def some_view(request):
    to_json = {
        "key1": "value1",
        "key2": "value2"
    }
    return HttpResponse(simplejson.dumps(to_json), mimetype='application/json')

Alternative:

from django.utils import simplejson

class JsonResponse(HttpResponse):
    """
        JSON response
    """
    def __init__(self, content, mimetype='application/json', status=None, content_type=None):

            status=status,
            content_type=content_type,

In Django 1.7 JsonResponse objects have been added to the Django framework itself which makes this task even easier:

from django.http import JsonResponse
def some_view(request):
    return JsonResponse({"key": "value"})

Arduino sketches are written in C++.

Here is a typical construct you'll encounter:

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
...
lcd.begin(16, 2);
lcd.print("Hello, World!");

That's C++, not C.

Hence do yourself a favor and learn C++. There are plenty of books and online resources available.

A new jQuery plugin for cookie retrieval and manipulation with binding for forms, etc: http://plugins.jquery.com/project/cookies

To be sure, you need to not only replace the single quotes, but as well the already escaped ones:

"first ' and \' second".replace(/'|\\'/g, "\\'")

Personally i think you should learn the hard way first. It will make you a better programmer and you will be able to solve that one of a kind issue when it comes up. After you can do it with pure JavaScript then using jQuery to speed up development is just an added bonus.

If you can do it the hard way then you can do it the easy way, it doesn't work the other way around. That applies to any programming paradigm.

It seems that in recent Pandas versions the way to go is to use df.assign:

df1 = df1.assign(e=np.random.randn(sLength))

It doesn't produce SettingWithCopyWarning.

You can change the mysql root password by logging in to the database directly (mysql -h your_host -u root) then run

SET PASSWORD FOR root@localhost = PASSWORD('yourpassword');

yqritc's RecyclerView-FlexibleDivider makes this a one liner. First add this to your build.gradle:

compile 'com.yqritc:recyclerview-flexibledivider:1.4.0' // requires jcenter()

Now you can configure and add a divder where you set your recyclerView's adapter:

recyclerView.setAdapter(myAdapter);
recyclerView.addItemDecoration(new HorizontalDividerItemDecoration.Builder(this).color(Color.RED).sizeResId(R.dimen.divider).marginResId(R.dimen.leftmargin, R.dimen.rightmargin).build());

Try this:

if [ ${STATUS} -ne 100 -a "${STRING}" = "${VALUE}" ]

or

if [ ${STATUS} -ne 100 ] && [ "${STRING}" = "${VALUE}" ]

use jQuery's $.getJSON

$.getJSON('mydata.json', function(data) {
    //do stuff with your data here
});

For some - possibly valid - reason the url was encoded twice. %25 is the urlencoded % sign. So the original url looked like:

http://server.com/my path/

Then it got urlencoded once:

http://server.com/my%20path/

and twice:

http://server.com/my%2520path/

So you should do no urlencoding - in your case - as other components seems to to that already for you. Use simply a space

This works:

myWindow = window.open('http://www.yahoo.com','myWindow', "width=200, height=200");

I was looking for the right method to handle those radio buttons here is an example for a solution I found here:

<tr *ngFor="let entry of entries">
    <td>{{ entry.description }}</td>
    <td>
        <input type="radio" name="radiogroup" 
            [value]="entry.id" 
            (change)="onSelectionChange(entry)">
    </td>
</tr>

Notice the onSelectionChange that passes the current element to the method.

The documentation could help you : http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/parsers/DocumentBuilder.html

The method DocumentBuilder.parse(String) takes a URI and tries to open it. If you want to directly give the content, you have to give it an InputStream or Reader, for example a StringReader. ... Welcome to the Java standard levels of indirections !

Basically :

DocumentBuilder db = ...;
String xml = ...;
db.parse(new InputSource(new StringReader(xml)));

Note that if you read your XML from a file, you can directly give the File object to DocumentBuilder.parse() .

As a side note, this is a pattern you will encounter a lot in Java. Usually, most API work with Streams more than with Strings. Using Streams means that potentially not all the content has to be loaded in memory at the same time, which can be a great idea !

The readarray command (also spelled mapfile) was introduced in bash 4.0.

readarray -t a < /path/to/filename

I too needed a rounded ImageView, I used the below code, you can modify it accordingly:

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Bitmap.Config;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

public class RoundedImageView extends ImageView {

    public RoundedImageView(Context context) {
        super(context);
    }

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

    public RoundedImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }
        Bitmap b = ((BitmapDrawable) drawable).getBitmap();
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth();
        @SuppressWarnings("unused")
        int h = getHeight();

        Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
        canvas.drawBitmap(roundBitmap, 0, 0, null);

    }

    public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
        Bitmap sbmp;

        if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
            float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
            float factor = smallest / radius;
            sbmp = Bitmap.createScaledBitmap(bmp,
                    (int) (bmp.getWidth() / factor),
                    (int) (bmp.getHeight() / factor), false);
        } else {
            sbmp = bmp;
        }

        Bitmap output = Bitmap.createBitmap(radius, radius, Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final String color = "#BAB399";
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, radius, radius);

        paint.setAntiAlias(true);
        paint.setFilterBitmap(true);
        paint.setDither(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.parseColor(color));
        canvas.drawCircle(radius / 2 + 0.7f, radius / 2 + 0.7f,
                radius / 2 + 0.1f, paint);
        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(sbmp, rect, rect, paint);

        return output;
    }

}

Because you didn't tell the linker about location of math library. Compile with gcc test.c -o test -lm

You can get the user name using System.Security.Principal.WindowsIdentity.GetCurrent() but there is not way to get current user password!

Another way to accomplish this is with the jq "--arg" flag. Using the original example:

#!/bin/sh

#this works ***
projectID=$(cat file.json | jq -r '.resource[] | 
select(.username=="[email protected]") | .id')
echo "$projectID"

[email protected]

# Use --arg to pass the variable to jq. This should work:
projectID=$(cat file.json | jq --arg EMAILID $EMAILID -r '.resource[] 
| select(.username=="$EMAILID") | .id')
echo "$projectID"

See here, which is where I found this solution: https://github.com/stedolan/jq/issues/626

This is an issue with the jdbc Driver version. I had this issue when I was using mysql-connector-java-commercial-5.0.3-bin.jar but when I changed to a later driver version mysql-connector-java-5.1.22.jar, the issue was fixed.

Here's a blog post that should help with escaping ticks in strings.

Here's the simplest method from said post:

The most simple and most used way is to use a single quotation mark with two single >quotation marks in both sides.

SELECT 'test single quote''' from dual;

The output of the above statement would be:

test single quote'

Simply stating you require an additional single quote character to print a single quote >character. That is if you put two single quote characters Oracle will print one. The first >one acts like an escape character.

This is the simplest way to print single quotation marks in Oracle. But it will get >complex when you have to print a set of quotation marks instead of just one. In this >situation the following method works fine. But it requires some more typing labour.

Automatically fill all form fields from an array

I'd suggest checking for an inner exception. If there isn't one, check your logs for the exception that occurred immediately prior to this one.

This isn't a web-specific exception, I've also encountered it in desktop-app development. In short, what's happening is that the thread receiving this exception is running some asynchronous code (via Invoke(), e.g.) and that code that's being run asynchronously is exploding with an exception. This target invocation exception is the aftermath of that failure.

If you haven't already, place some sort of exception logging wrapper around the asynchronous callbacks that are being invoked when you trigger this error. Event handlers, for instance. That ought to help you track down the problem.

Good luck!

You need to leverage the @ViewChild decorator to reference the child component from the parent one by injection:

import { Component, ViewChild } from 'angular2/core';  

(...)

@Component({
  selector: 'my-app',
  template: `
    <h1>My First Angular 2 App</h1>
    <child></child>
    <button (click)="submit()">Submit</button>
  `,
  directives:[App]
})
export class AppComponent { 
  @ViewChild(Child) child:Child;

  (...)

  someOtherMethod() {
    this.searchBar.someMethod();
  }
}

Here is the updated plunkr: http://plnkr.co/edit/mrVK2j3hJQ04n8vlXLXt?p=preview.

You can notice that the @Query parameter decorator could also be used:

export class AppComponent { 
  constructor(@Query(Child) children:QueryList<Child>) {
    this.childcmp = children.first();
  }

  (...)
}

Perhaps you want something like:

<style name="CustomActivityTheme" parent="@android:style/Theme.Holo">
    <item name="android:checkboxStyle">@style/customCheckBoxStyle</item>
</style>

<style name="customCheckBoxStyle" parent="@android:style/Widget.CompoundButton.CheckBox">
    <item name="android:textColor">@android:color/black</item>
</style>

Note, the textColor item.

Generate the scripts?

Generate a script to create the table then generate a script to insert the data.

check-out SP_ Genereate_Inserts for generating the data insert script.

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

Please check permission "images/" directory

You can use the auto_now and auto_now_add options for updated_at and created_at respectively.

class MyModel(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

First, check whether the strict mode is enabled or not in mysql using:

     SHOW VARIABLES LIKE 'sql_mode';

If you want to disable it:

     SET sql_mode = '';

or any other mode can be set except the following. To enable strict mode:

     SET sql_mode = 'STRICT_TRANS_TABLES';

You can check the result from the first mysql query.

I had a slightly different problem. I worked with inputs in a modal and it drove me mad. No of the proposed solutions worked for me.

Until i found this issue: https://github.com/valor-software/ngx-bootstrap/issues/1597

This good guy gave me the hint that ngx-bootstrap modal has a focus configuration. If this configuration is not set to false, the modal will be focused after the animation and there is NO WAY to focus anything else.

Update:

To set this configuration, add the following attribute to the modal div:

[config]="{focus: false}"

Update 2:

To force the focus on the input field i wrote a directive and set the focus in every AfterViewChecked cycle as long as the input field has the class ng-untouched.

 ngAfterViewChecked() {
    // This dirty hack is needed to force focus on an input element of a modal.
    if (this.el.nativeElement.classList.contains('ng-untouched')) {
        this.renderer.invokeElementMethod(this.el.nativeElement, 'focus', []);
    }
}

In android studio you may see the following folder drawable xhdpi, drawable-hdpi, drawable-mdpi and more... You can put images of different dpi in these folder accordingly and android will take care which images should be draw according to the screen density of device.

NOTE: You have to put the images with the same name.

\t is a tab character. Use a raw string instead:

test_file=open(r'c:\Python27\test.txt','r')

or double the slashes:

test_file=open('c:\\Python27\\test.txt','r')

or use forward slashes instead:

test_file=open('c:/Python27/test.txt','r')

For legacy code in Python 2.7, can do it via BeautifulSoup4:

>>> bs4.dammit import EntitySubstitution
>>> esub = EntitySubstitution()
>>> esub.substitute_html("r&d")
'r&d'

Can you check with firebug if do you get some 404? I had problems in the pass and I found that the extension was the same but linux file.ttf is different from file.TTF... and it worked with all browsers except firefox.

Wish it helps!

Answer given by user @JPM and @usman are really very useful. It works fine but in my case it come in onReceive multiple time in my case 4 times so my code execute multiple time.

I do some modification and make as per my requirement and now it comes only 1 time

Here is java class for Broadcast.

public class WifiReceiver extends BroadcastReceiver {

String TAG = getClass().getSimpleName();
private Context mContext;

@Override
public void onReceive(Context context, Intent intent) {

    mContext = context;


    if (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {

        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = cm.getActiveNetworkInfo();

        if (networkInfo != null && networkInfo.getType() == ConnectivityManager.TYPE_WIFI &&
                networkInfo.isConnected()) {
            // Wifi is connected
            WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
            WifiInfo wifiInfo = wifiManager.getConnectionInfo();
            String ssid = wifiInfo.getSSID();

            Log.e(TAG, " -- Wifi connected --- " + " SSID " + ssid );

        }
    }
    else if (intent.getAction().equalsIgnoreCase(WifiManager.WIFI_STATE_CHANGED_ACTION))
    {
        int wifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, WifiManager.WIFI_STATE_UNKNOWN);
        if (wifiState == WifiManager.WIFI_STATE_DISABLED)
        {
            Log.e(TAG, " ----- Wifi  Disconnected ----- ");
        }

    }
}
}

In AndroidManifest

<receiver android:name=".util.WifiReceiver" android:enabled="true">
        <intent-filter>
            <action android:name="android.net.wifi.WIFI_STATE_CHANGED" />
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>
        </intent-filter>
    </receiver>


<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

After making no changes to a production server we began receiving this error. After trying several different things and thinking that perhaps there were DNS issues, restarting IIS fixed the issue (restarting only the site did not fix the issue). It likely won't work for everyone but if we tried that first it would have saved a lot of time.

I solved the problem. I made mistake in setData(Uri) and setType(String).

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/download/" + "app.apk")), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

That is correct now, my auto-update is working. Thanks for help. =)

Edit 20.7.2016:

After a long time, I had to use this way of updating again in another project. I encountered a number of problems with old solution. A lot of things have changed in that time, so I had to do this with a different approach. Here is the code:

    //get destination to update file and set Uri
    //TODO: First I wanted to store my update .apk file on internal storage for my app but apparently android does not allow you to open and install
    //aplication with existing package from there. So for me, alternative solution is Download directory in external storage. If there is better
    //solution, please inform us in comment
    String destination = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/";
    String fileName = "AppName.apk";
    destination += fileName;
    final Uri uri = Uri.parse("file://" + destination);

    //Delete update file if exists
    File file = new File(destination);
    if (file.exists())
    //file.delete() - test this, I think sometimes it doesnt work
        file.delete();

    //get url of app on server
    String url = Main.this.getString(R.string.update_app_url);

    //set downloadmanager
    DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
    request.setDescription(Main.this.getString(R.string.notification_description));
    request.setTitle(Main.this.getString(R.string.app_name));

    //set destination
    request.setDestinationUri(uri);

    // get download service and enqueue file
    final DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
    final long downloadId = manager.enqueue(request);

    //set BroadcastReceiver to install app when .apk is downloaded
    BroadcastReceiver onComplete = new BroadcastReceiver() {
        public void onReceive(Context ctxt, Intent intent) {
            Intent install = new Intent(Intent.ACTION_VIEW);
            install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            install.setDataAndType(uri,
                    manager.getMimeTypeForDownloadedFile(downloadId));
            startActivity(install);

            unregisterReceiver(this);
            finish();
        }
    };
    //register receiver for when .apk download is compete
    registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));

try,

str_list = " ".join([str(ele) for ele in numlist])

this statement will give you each element of your list in string format

print("The list now looks like [{0}]".format(str_list))

and,

change print(numlist.pop(2)+" has been removed") to

print("{0} has been removed".format(numlist.pop(2)))

as well.

Using VS Professional 2019, I was trying to run a downloaded solution from a Udemy class on selenium automation testing, and most of the projects had errors in the project references sections. I tried cleaning, rebuilding, closing VS. Then, in VS, when I right clicked on the solution in Solution Explorer and chose Manage Nuget Packages for Solution, there were 2 available updates: for MSTest.TestAdapter and MSTest.TestFramework, and when I installed those, the error messages on the references for all the projects went away, for the references to those, as well as for the references to System and System.Core.

I received same error despite jar being in lib directory & added to deployment assembly in Eclipse.

So I doubted two things ,

1.Some Weblogic cache issue - as this app was deployed before & I was trying to redeploy after some changes

2.Jar itself is corrupt due to partial download etc

So I re downloaded the jar & deleted everything in directory - ..\Oracle_Home\user_projects\domains\base_domain\lib and redeployed again & all went well.

chmod +x openfire worked for me. It adds execution permission to the openfire folder.

Although the question is about GitHub flavored Markdown, I think it's worth mentioning that as of 2013, GitHub supports AsciiDoc which has this feature builtin. You only need to rename your file with a .adoc extension and use:

A statement.footnote:[Clarification about this statement.]

A bold statement!footnote:disclaimer[Opinions are my own.]

Another bold statement.footnote:disclaimer[]

Documentation along with the final result is here.

It is a self-executing anonymous function. The first set of brackets contain the expressions to be executed, and the second set of brackets executes those expressions.

(function () {
    return ( 10 + 20 );
})();

Peter Michaux discusses the difference in An Important Pair of Parentheses.

It is a useful construct when trying to hide variables from the parent namespace. All the code within the function is contained in the private scope of the function, meaning it can't be accessed at all from outside the function, making it truly private.

2. JavaScript Namespacing

Although I've tried all the previous answers, only the following one worked out:

If you're using Angular's ng-repeat to populate the table hackel's jquery snippet will not work by placing it in the document load event. You'll need to run the snippet after angular has finished rendering the table.

To trigger an event after ng-repeat has rendered try this directive:

var app = angular.module('myapp', [])
.directive('onFinishRender', function ($timeout) {
return {
    restrict: 'A',
    link: function (scope, element, attr) {
        if (scope.$last === true) {
            $timeout(function () {
                scope.$emit('ngRepeatFinished');
            });
        }
    }

I got the directive from here: Use AngularJS just for routing purposes

While it is possible to combine the results, I would advise against doing so.

You have two fundamentally different types of queries that return a different number of rows, a different number of columns and different types of data. It would be best to leave it as it is - two separate queries.

You are going to have to truncate the values yourself as strings before you put them into that column.

Otherwise, if you want more decimal places, you will need to change your declaration of the decimal column.

I believe you are looking for this:

string str = "{\"Arg1\":\"Arg1Value\",\"Arg2\":\"Arg2Value\"}";
JavaScriptSerializer serializer1 = new JavaScriptSerializer();
object obje = serializer1.Deserialize(str, obj1.GetType());

If you're willing to include the jQuery UI library, in addition to jQuery itself, then you can simply use hide(), with additional arguments, as follows:

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this).hide('slide',{direction:'right'},1000);

            });
    });

JS Fiddle demo.

Without using jQuery UI, you could achieve your aim just using animate():

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this)
                    .animate(
                        {
                            'margin-left':'1000px'
                            // to move it towards the right and, probably, off-screen.
                        },1000,
                        function(){
                            $(this).slideUp('fast');
                            // once it's finished moving to the right, just 
                            // removes the the element from the display, you could use
                            // `remove()` instead, or whatever.
                        }
                        );

            });
    });

If you do choose to use jQuery UI, then I'd recommend linking to the Google-hosted code, at: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js

I think I have found a utility that meets the need for the tail function in batch files. It's called "mtee", and it's free. I've incorporated it into a batch file I'm working on and it does the job very nicely. Just make sure to put the executable into a directory in the PATH statement, and away you go.

Here's the link:

You could also have a look at testing using Groovy. In Groovy you can easily mock Java interfaces using the 'as' operator:

def request = [isUserInRole: { roleName -> roleName == "testRole"}] as HttpServletRequest 

Apart from this basic functionality Groovy offers a lot more on the mocking front, including the powerful MockFor and StubFor classes.

My solution was to use a short nickname (less than 31 characters) and then write the entire name in cell 0.

How do I catch multiple exceptions in one line (except block)

Do this:

try:
    may_raise_specific_errors():
except (SpecificErrorOne, SpecificErrorTwo) as error:
    handle(error) # might log or have some other default behavior...

The parentheses are required due to older syntax that used the commas to assign the error object to a name. The as keyword is used for the assignment. You can use any name for the error object, I prefer error personally.

Best Practice

To do this in a manner currently and forward compatible with Python, you need to separate the Exceptions with commas and wrap them with parentheses to differentiate from earlier syntax that assigned the exception instance to a variable name by following the Exception type to be caught with a comma.

Here's an example of simple usage:

import sys

try:
    mainstuff()
except (KeyboardInterrupt, EOFError): # the parens are necessary
    sys.exit(0)

I'm specifying only these exceptions to avoid hiding bugs, which if I encounter I expect the full stack trace from.

This is documented here: https://docs.python.org/tutorial/errors.html

You can assign the exception to a variable, (e is common, but you might prefer a more verbose variable if you have long exception handling or your IDE only highlights selections larger than that, as mine does.) The instance has an args attribute. Here is an example:

import sys

try:
    mainstuff()
except (KeyboardInterrupt, EOFError) as err: 
    print(err)
    print(err.args)
    sys.exit(0)

Note that in Python 3, the err object falls out of scope when the except block is concluded.

Deprecated

You may see code that assigns the error with a comma. This usage, the only form available in Python 2.5 and earlier, is deprecated, and if you wish your code to be forward compatible in Python 3, you should update the syntax to use the new form:

import sys

try:
    mainstuff()
except (KeyboardInterrupt, EOFError), err: # don't do this in Python 2.6+
    print err
    print err.args
    sys.exit(0)

If you see the comma name assignment in your codebase, and you're using Python 2.5 or higher, switch to the new way of doing it so your code remains compatible when you upgrade.

The suppress context manager

The accepted answer is really 4 lines of code, minimum:

try:
    do_something()
except (IDontLikeYouException, YouAreBeingMeanException) as e:
    pass

The try, except, pass lines can be handled in a single line with the suppress context manager, available in Python 3.4:

from contextlib import suppress

with suppress(IDontLikeYouException, YouAreBeingMeanException):
     do_something()

So when you want to pass on certain exceptions, use suppress.

Link with -static. When you link with -static the linker embeds the library inside the executable, so the executable will be bigger, but it can be executed on a system with an older version of glibc because the program will use it's own library instead of that of the system.

.so files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.

.a files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar command -- a predecessor of tar that's now just used for making libraries) of the original .o object files.

.la files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?

Static and dynamic libraries each have pros and cons.

Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.

Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.

Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.

Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.

Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.

Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.

Dynamic libraries are especially useful for system libraries, like libc. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.

You can do it using clone() function of jQuery, Accepted answer is ok but i am providing alternative to it, you can use append(), but it works only if you can change html slightly as below:

$(document).ready(function(){_x000D_
    $('#clone_btn').click(function(){_x000D_
      $("#car_parent").append($("#car2").clone());_x000D_
    });_x000D_
});

.car-well{_x000D_
  border:1px solid #ccc;_x000D_
  text-align: center;_x000D_
  margin: 5px;_x000D_

        (IL, ILC) => new { INDIVIDUALLICENSE = IL, INDLICENSECLAsse = ILC })
    .Where(o => 
        o.INDIVIDUALLICENSE.GLOBALENTITYID == "ABC" &&
        o.INDIVIDUALLICENSE.LICENSE_TYPE == "ABC")
    .Select(t => new

    .OrderBy(x => x.name);

You will have to use javascript, or the JQuery framework to do that. her is an example using Jquery

   $('#toggle').click(function () {
        //check if checkbox is checked
        if ($(this).is(':checked')) {

            $('#sendNewSms').removeAttr('disabled'); //enable input

        } else {
            $('#sendNewSms').attr('disabled', true); //disable input
        }
    });

A clustered index is essentially a sorted copy of the data in the indexed columns.

The main advantage of a clustered index is that when your query (seek) locates the data in the index then no additional IO is needed to retrieve that data.

The overhead of maintaining a clustered index, especially in a frequently updated table, can lead to poor performance and for that reason it may be preferable to create a non-clustered index.

Using your data:

test_data <- data.frame(
var0 = 100 + c(0, cumsum(runif(49, -20, 20))),
var1 = 150 + c(0, cumsum(runif(49, -10, 10))),
Dates = seq.Date(as.Date("2002-01-01"), by="1 month", length.out=100))

I create a stacked version which is what ggplot() would like to work with:

stacked <- with(test_data,
                data.frame(value = c(var0, var1),
                           variable = factor(rep(c("Var0","Var1"),
                                                 each = NROW(test_data))),
                           Dates = rep(Dates, 2)))

In this case producing stacked was quite easy as we only had to do a couple of manipulations, but reshape() and the reshape and reshape2 might be useful if you have a more complex real data set to manipulate.

Once the data are in this stacked form, it only requires a simple ggplot() call to produce the plot you wanted with all the extras (one reason why higher-level plotting packages like lattice and ggplot2 are so useful):

require(ggplot2)
p <- ggplot(stacked, aes(Dates, value, colour = variable))
p + geom_line()

I'll leave it to you to tidy up the axis labels, legend title etc.

HTH

Use the backslash to escape a character. For example:

/\\d/

This will match \d instead of a numeric character

There's no fully compliant, official HTML way to do it, but a little javascript can go a long way. Another problem you'll run into is that disabled fields don't show up in the POST data

Telerik also has a combo box control. Essentially, it's a textbox with images that when you click on them reveal a panel with a list of predefined options.

http://demos.telerik.com/aspnet-ajax/combobox/examples/overview/defaultcs.aspx

But this is AJAX, so it may have a larger footprint than you want on your website (since you say it's "HTML").

The error comes when you try to call sum(x) and x is a factor.

What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)

simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:

family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))

For a detailed explanation of why the intermediate as.character step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?

The easiest-to-understand definition of Aggregate is that it performs an operation on each element of the list taking into account the operations that have gone before. That is to say it performs the action on the first and second element and carries the result forward. Then it operates on the previous result and the third element and carries forward. etc.

Example 1. Summing numbers

var nums = new[]{1,2,3,4};
var sum = nums.Aggregate( (a,b) => a + b);
Console.WriteLine(sum); // output: 10 (1+2+3+4)

This adds 1 and 2 to make 3. Then adds 3 (result of previous) and 3 (next element in sequence) to make 6. Then adds 6 and 4 to make 10.

Example 2. create a csv from an array of strings

var chars = new []{"a","b","c", "d"};
var csv = chars.Aggregate( (a,b) => a + ',' + b);
Console.WriteLine(csv); // Output a,b,c,d

This works in much the same way. Concatenate a a comma and b to make a,b. Then concatenates a,b with a comma and c to make a,b,c. and so on.

Example 3. Multiplying numbers using a seed

For completeness, there is an overload of Aggregate which takes a seed value.

var multipliers = new []{10,20,30,40};
var multiplied = multipliers.Aggregate(5, (a,b) => a * b);
Console.WriteLine(multiplied); //Output 1200000 ((((5*10)*20)*30)*40)

Much like the above examples, this starts with a value of 5 and multiplies it by the first element of the sequence 10 giving a result of 50. This result is carried forward and multiplied by the next number in the sequence 20 to give a result of 1000. This continues through the remaining 2 element of the sequence.

Docs: http://msdn.microsoft.com/en-us/library/bb548651.aspx

Addendum

Example 2, above, uses string concatenation to create a list of values separated by a comma. This is a simplistic way to explain the use of Aggregate which was the intention of this answer. However, if using this technique to actually create a large amount of comma separated data, it would be more appropriate to use a StringBuilder, and this is entirely compatible with Aggregate using the seeded overload to initiate the StringBuilder.

var chars = new []{"a","b","c", "d"};
var csv = chars.Aggregate(new StringBuilder(), (a,b) => {
    if(a.Length>0)
        a.Append(",");
    a.Append(b);
    return a;
});
Console.WriteLine(csv);

For Spooling in Oracle SQL Developer, here is the solution.

set heading on

set linesize 1500

set colsep '|'

set numformat 99999999999999999999

set pagesize 25000

spool E:\abc.txt

@E:\abc.sql;

spool off

The hint is :

1. when we spool from sql plus , then the whole query is required.

2. when we spool from Oracle Sql Developer , then the reference path of the query required as given in the specified example.

I've found this to work for my code,, however my code is getting the class out of an array within a for loop.

String className="";

className = list[i].getClass().getCanonicalName();

System.out.print(className); //Use this to test it works

For C++:

As mentioned by others, when possible (i.e. when you only want each element at a time) it is strongly preferable to use iterators to both be explicit and avoid common pitfalls. Modern C++ has a more concise syntax for that with auto:

std::vector<int> vec = {1,2,3,4};
for (auto it = vec.rbegin(); it != vec.rend(); ++it) {
    std::cout<<*it<<" ";
}

prints 4 3 2 1 .

You can also modify the value during the loop:

std::vector<int> vec = {1,2,3,4};
for (auto it = vec.rbegin(); it != vec.rend(); ++it) {
    *it = *it + 10;
    std::cout<<*it<<" ";
}

leading to 14 13 12 11 being printed and {11, 12, 13, 14} being in the std::vector afterwards.

If you don't plan on modifying the value during the loop, you should make sure that you get an error when you try to do that by accident, similarly to how one might write for(const auto& element : vec). This is possible like this:

std::vector<int> vec = {1,2,3,4};
for (auto it = vec.crbegin(); it != vec.crend(); ++it) { // used crbegin()/crend() here...
    *it = *it + 10; // ... so that this is a compile-time error
    std::cout<<*it<<" ";
}

The compiler error in this case for me is:

/tmp/main.cpp:20:9: error: assignment of read-only location ‘it.std::reverse_iterator<__gnu_cxx::__normal_iterator<const int*, std::vector<int> > >::operator*()’
   20 |     *it = *it + 10;
      |     ~~~~^~~~~~~~~~

Also note that you should make sure not to use different iterator types together:

std::vector<int> vec = {1,2,3,4};
for (auto it = vec.rbegin(); it != vec.end(); ++it) { // mixed rbegin() and end()
    std::cout<<*it<<" ";
}

leads to the verbose error:

/tmp/main.cpp: In function ‘int main()’:
/tmp/main.cpp:19:33: error: no match for ‘operator!=’ (operand types are ‘std::reverse_iterator<__gnu_cxx::__normal_iterator<int*, std::vector<int> > >’ and ‘std::vector<int>::iterator’ {aka ‘__gnu_cxx::__normal_iterator<int*, std::vector<int> >’})
   19 | for (auto it = vec.rbegin(); it != vec.end(); ++it) {
      |                              ~~ ^~ ~~~~~~~~~
      |                              |            |
      |                              |            std::vector<int>::iterator {aka __gnu_cxx::__normal_iterator<int*, std::vector<int> >}
      |                              std::reverse_iterator<__gnu_cxx::__normal_iterator<int*, std::vector<int> > >

If you have C-style arrays on the stack, you can do things like this:

int vec[] = {1,2,3,4};
for (auto it = std::crbegin(vec); it != std::crend(vec); ++it) {
    std::cout<<*it<<" ";
}

If you really need the index, consider the following options:

• check the range, then work with signed values, e.g.:

void loop_reverse(std::vector<int>& vec) {
    if (vec.size() > static_cast<size_t>(std::numeric_limits<int>::max())) {
        throw std::invalid_argument("Input too large");
    }
    const int sz = static_cast<int>(vec.size());
    for(int i=sz-1; i >= 0; --i) {
        // do something with i
    }
}

• Work with unsigned values, be careful, and add comments, e.g.:

void loop_reverse2(std::vector<int>& vec) {
    for(size_t i=vec.size(); i-- > 0;) { // reverse indices from N-1 to 0
        // do something with i
    }
}

• calculate the actual index separately, e.g.:

void loop_reverse3(std::vector<int>& vec) {
    for(size_t offset=0; offset < vec.size(); ++offset) {
        const size_t i = vec.size()-1-offset; // reverse indices from N-1 to 0
        // do something with i
    }
}

Use LoadPatientRecords() after a successful insertion.

Try the below code

private void btnSubmit_Click(object sender, EventArgs e)
{
        if (btnSubmit.Text == "Clear")
        {
            btnSubmit.Text = "Submit";

            txtpFirstName.Focus();
        }
        else
        {
           btnSubmit.Text = "Clear";
           int result = AddPatientRecord();
           if (result > 0)
           {
               MessageBox.Show("Insert Successful");

               LoadPatientRecords();
           }
           else
               MessageBox.Show("Insert Fail");
         }
}

As explained above, a Class cannot be static unless it's a member of another Class.

If you're looking to design a class "of which there cannot be multiple instances", you may want to look into the "Singleton" design pattern.

Beginner Singleton info here.

Caveat:

If you are thinking of using the singleton pattern, resist with all your might. It is one of the easiest DesignPatterns to understand, probably the most popular, and definitely the most abused. (source: JavaRanch as linked above)

Each image has a resource-number, which is an integer. Pass this number to "setImageResource" and you should be ok.

Check this link for further information:
http://developer.android.com/guide/topics/resources/accessing-resources.html

e.g.:

imageView.setImageResource(R.drawable.myimage);

If in case you are using Python 3.x, you have to use

txt_entry = Entry(root)

txt_entry.pack()

txt_entry.delete(0, tkinter.END)

Convert file format to png

string newfilename , 
 string filename = "~/Photo/"  + lbl_ImgPath.Text.ToString();/*get filename from specific path where we store image*/
 string newfilename = Path.ChangeExtension(filename, ".png");/*Convert file format from jpg to png*/

As an alternative to rendering a raster image, you can embed a SVG file:

<a><img src="http://dump.thecybershadow.net/6c736bfd11ded8cdc5e2bda009a6694a/colortext.svg"/></a>

You can then add color text to the SVG file as usual:

<?xml version="1.0" encoding="utf-8"?>
<svg version="1.1" 
     xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink"
     width="100" height="50"
>
  <text font-size="16" x="10" y="20">
    <tspan fill="red">Hello</tspan>,
    <tspan fill="green">world</tspan>!
  </text>
</svg>

Unfortunately, even though you can select and copy text when you open the .svg file, the text is not selectable when the SVG image is embedded.

Demo: https://gist.github.com/CyberShadow/95621a949b07db295000

Something like:

var rnd = new Random(DateTime.Now.Millisecond);
int ticks = rnd.Next(0, 3000);

You have to set the http header at the http response of your resource. So it needs to be set serverside, you can remove the "HTTP_OPTIONS"-header from your angular HTTP-Post request.

In my opinion db4o is the easiest way to go. Here you can find a tutorial: http://community.versant.com/documentation/reference/db4o-7.12/java/tutorial/

And here you can download the library:

http://www.db4o.com/community/download.aspx?file=db4o-8.0-java.zip

(Just put the db4o-8.0...-all-java5.jar in the lib directory into your project's libs folder. If there is no libs folder in you project create it)

As db4o is a object oriented database system you can directly save you objects into the database and later get them back.

Follow these steps in order to generate the correct key hashes.

1. Open your project in android studio and run the project.
2. Click on Gradle menu.
3. Select your app and expand task tree.
4. Double click on android -> signingReport and see the magic
5. Result after clicking above tab
6. Copy the SHA1 key and browse SHA1 key to key hash
7. After converting the SHA1 key to key hash copy the new key hash and paste it in facebook console. This will work like charm.

Why :not just use two :not:

input:not([type="radio"]):not([type="checkbox"])

_{Yes, it is intentional}

Use this function:

function is_checkbox(selector) {
    var $result = $(selector);
    return $result[0] && $result[0].type === 'checkbox';
};

Or this jquery plugin:

$.fn.is_checkbox = function () { return this.is(':checkbox'); };

I tried using the try{}catch{} method but it did not work for me. However, when I switched to using .then(...).catch(...), the AxiosError is caught correctly that I can play around with. When I try the former when putting a breakpoint, it does not allow me to see the AxiosError and instead, says to me that the caught error is undefined, which is also what eventually gets displayed in the UI.

Not sure why this happens I find it very trivial. Either way due to this, I suggest using the conventional .then(...).catch(...) method mentioned above to avoid throwing undefined errors to the user.

Use hamcrest Matcher containsString()

// Hamcrest assertion
assertThat(person.getName(), containsString("myName"));

// Error Message
java.lang.AssertionError:
Expected: a string containing "myName"
     got: "some other name"

You can optional add an even more detail error message.

// Hamcrest assertion with custom error message
assertThat("my error message", person.getName(), containsString("myName"));

// Error Message
java.lang.AssertionError: my error message
Expected: a string containing "myName"
     got: "some other name"

Posted my answer to a duplicate question here

In 3 words: inline-block is better.

Inline Block

The only drawback to the display: inline-block approach is that in IE7 and below an element can only be displayed inline-block if it was already inline by default. What this means is that instead of using a <div> element you have to use a <span> element. It's not really a huge drawback at all because semantically a <div> is for dividing the page while a <span> is just for covering a span of a page, so there's not a huge semantic difference. A huge benefit of display:inline-block is that when other developers are maintaining your code at a later point, it is much more obvious what display:inline-block and text-align:right is trying to accomplish than a float:left or float:right statement. My favorite benefit of the inline-block approach is that it's easy to use vertical-align: middle, line-height and text-align: center to perfectly center the elements, in a way that is intuitive. I found a great blog post on how to implement cross-browser inline-block, on the Mozilla blog. Here is the browser compatibility.

Float

The reason that using the float method is not suited for layout of your page is because the float CSS property was originally intended only to have text wrap around an image (magazine style) and is, by design, not best suited for general page layout purposes. When changing floated elements later, sometimes you will have positioning issues because they are not in the page flow. Another disadvantage is that it generally requires a clearfix otherwise it may break aspects of the page. The clearfix requires adding an element after the floated elements to stop their parent from collapsing around them which crosses the semantic line between separating style from content and is thus an anti-pattern in web development.

Any white space problems mentioned in the link above could easily be fixed with the white-space CSS property.

Edit:

SitePoint is a very credible source for web design advice and they seem to have the same opinion that I do:

If you’re new to CSS layouts, you’d be forgiven for thinking that using CSS floats in imaginative ways is the height of skill. If you have consumed as many CSS layout tutorials as you can find, you might suppose that mastering floats is a rite of passage. You’ll be dazzled by the ingenuity, astounded by the complexity, and you’ll gain a sense of achievement when you finally understand how floats work.

Don’t be fooled. You’re being brainwashed.

2015 Update - Flexbox is a good alternative for modern browsers:

.container {
  display: flex; /* or inline-flex */
}

.item {
  flex: none | [ <'flex-grow'> <'flex-shrink'>? || <'flex-basis'> ]
}

More info

Dec 21, 2016 Update

Bootstrap 4 is removing support for IE9, and thus is getting rid of floats from rows and going full Flexbox.

Pull request #21389

Looks like you created a separate question. I was answering your other question How to change flat file source using foreach loop container in an SSIS package? with the same answer. Anyway, here it is again.

Create two string data type variables namely DirPath and FilePath. Set the value C:\backup\ to the variable DirPath. Do not set any value to the variable FilePath.

Select the variable FilePath and select F4 to view the properties. Set the EvaluateAsExpression property to True and set the Expression property as @[User::DirPath] + "Source" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE()) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)

I've found that this is a sign that the server where you're deploying code has an old .NET framework installed that doesn't support TLS 1.1 or TLS 1.2. Steps to fix:

1. Installing the latest .NET Runtime on your production servers (IIS & SQL)
2. Installing the latest .NET Developer Pack on your development machines.
3. Change the "Target framework" settings in your Visual Studio projects to the latest .NET framework.

You can get the latest .NET Developer Pack and Runtime from this URL: http://getdotnet.azurewebsites.net/target-dotnet-platforms.html

Several ways to check if an object property exists.

const dog = { name: "Spot" }

if (dog.name) console.log("Yay 1"); // Prints.
if (dog.sex) console.log("Yay 2"); // Doesn't print. 

if ("name" in dog) console.log("Yay 3"); // Prints.
if ("sex" in dog) console.log("Yay 4"); // Doesn't print.

if (dog.hasOwnProperty("name")) console.log("Yay 5"); // Prints.
if (dog.hasOwnProperty("sex")) console.log("Yay 6"); // Doesn't print, but prints undefined.

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

Based on semver, you can use

• Hyphen Ranges X.Y.Z - A.B.C 1.2.3-2.3.4 Indicates >=1.2.3 <=2.3.4

• X-Ranges 1.2.x 1.X 1.2.*

• Tilde Ranges ~1.2.3 ~1.2 Indicates allowing patch-level changes or minor version changes.

• Caret Ranges ^1.2.3 ^0.2.5 ^0.0.4

  Allows changes that do not modify the left-most non-zero digit in the [major, minor, patch] tuple

  • ^1.2.x (means >=1.2.0 <2.0.0)
  • ^0.0.x (means >=0.0.0 <0.1.0)
  • ^0.0 (means >=0.0.0 <0.1.0)

Chain both class selectors (without a space in between):

.foo.bar {
    /* Styles for element(s) with foo AND bar classes */
}

If you still have to deal with ancient browsers like IE6, be aware that it doesn't read chained class selectors correctly: it'll only read the last class selector (.bar in this case) instead, regardless of what other classes you list.

To illustrate how other browsers and IE6 interpret this, consider this CSS:

* {
    color: black;
}

.foo.bar {
    color: red;
}

Output on supported browsers is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Not selected, black text [3] -->

Output on IE6 is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Selected, red text [2] -->

Footnotes:

• Supported browsers:
  1. Not selected as this element only has class foo.
  2. Selected as this element has both classes foo and bar.
  3. Not selected as this element only has class bar.
     
     
• IE6:
  1. Not selected as this element doesn't have class bar.
  2. Selected as this element has class bar, regardless of any other classes listed.

Python 2.5.2 (r252:60911, Sep 27 2008, 07:03:14)
[GCC 4.3.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> print "hello",; print "there"
hello there
>>> print "hello",; sys.stdout.softspace=False; print "there"
hellothere

But really, you should use sys.stdout.write directly.

I think you can use Padding like: Hope this one can help you.

.loginButton {
    background:url(images/loginBtn-center.jpg) repeat-x;
    width:175px;
    height:65px;
    margin:20px auto;
    border-radius:10px;
    -webkit-border-radius:10px;
    box-shadow:0 1px 2px #5e5d5b;
    <!--Using padding to align text in box or image-->
    padding: 3px 2px;
}

I met the error: "The transaction log for database '...' is full due to 'ACTIVE_TRANSACTION' while deleting old rows from tables of my database for freeing disk space. I realized that this error would occur if the number of rows to be deleted was bigger than 1000000 in my case. So instead of using 1 DELETE statement, i divided the delete task by using DELETE TOP (1000000).... statement.

For example:

instead of using this statement:

DELETE FROM Vt30 WHERE Rt < DATEADD(YEAR, -1, GETDATE())

using following statement repeatedly:

DELETE TOP(1000000) FROM Vt30 WHERE Rt < DATEADD(YEAR, -1, GETDATE())

To get the latest stable version just run

npm install npm@latest -g

It worked just fine for me!

My personal preference is to delete the branch name after I’m done with a topic branch.

Instead of trying to use the branch name to explain the meaning of the branch, I start the subject line of the commit message in the first commit on that branch with “Branch:” and include further explanations in the body of the message if the subject does not give me enough space.

The branch name in my use is purely a handle for referring to a topic branch while working on it. Once work on the topic branch has concluded, I get rid of the branch name, sometimes tagging the commit for later reference.

That makes the output of git branch more useful as well: it only lists long-lived branches and active topic branches, not all branches ever.

You can use Ctrl + Shift + F which will run your formatter on the file and fix indentations along the way also.

Reference: https://developer.apple.com/ios/human-interface-guidelines/graphics/custom-icons/[https://developer.apple.com/ios/human-interface-guidelines/graphics/custom-icons/].

So the 50x50 size is a good choice.

var test = {'red':'#FF0000', 'blue':'#0000FF'};_x000D_
delete test.blue; // or use => delete test['blue'];_x000D_
console.log(test);

this deletes test.blue

You can add colon before attribute (also can use conditions) like

<div :class="current? 'active': '' " > 
<button :disabled="InvalidForm? true : false " >

If you want to set a dynamic value like props then you also can use colon before attribute name like :

<Child :data="userList" />

A corresponding cross for ✓ ✓ would be ✗ ✗ I think (Dingbats).

If you are using ajax, it is possible to add the options xhrFields: { responseType: 'blob' }:

$.ajax({
  url: 'yourURL',
  type: 'POST',
  data: yourData,
  xhrFields: { responseType: 'blob' },
  success: function (data, textStatus, jqXHR) {
    let src = window.URL.createObjectURL(data);
  }
});

You can use require() if you want to install packages if and only if necessary, such as:

if (!require(package, character.only=T, quietly=T)) {
    install.packages(package)
    library(package, character.only=T)
}

For multiple packages you can use

for (package in c('<package1>', '<package2>')) {
    if (!require(package, character.only=T, quietly=T)) {
        install.packages(package)
        library(package, character.only=T)
    }
}

Pro tips:

• When used inside the script, you can avoid a dialog screen by specifying the repos parameter of install.packages(), such as

  install.packages(package, repos="http://cran.us.r-project.org")
  

• You can wrap require() and library() in suppressPackageStartupMessages() to, well, suppress package startup messages, and also use the parameters require(..., quietly=T, warn.conflicts=F) if needed to keep the installs quiet.

It was my own stupidity:

java.text.DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getApplicationContext());

Putting this inside onCreate() method fixed my problem.

See here - http://my.opera.com/community/forums/topic.dml?id=1319992&t=1331393279&page=1#comment11751402

Essentially:

history.pushState('data', '', 'http://your-domain/path');

You can manipulate the history object to make this work.

It only works on the same domain, but since you're satisfied with using the hash tag approach, that shouldn't matter.

Obviously would need to be cross-browser tested, but since that was posted on the Opera forum I'm safe to assume it would work in Opera, and I just tested it in Chrome and it worked fine.

If the button tag is inside the div element who contains the modal, you can do something like:

<button class="btn btn-default" data-dismiss="modal" aria-label="Close">Cancel</button>

        </xsl:if>

            </xsl:if>
            <xsl:if test="LE_ADDR2 !='' ">
                <xsl:value-of select="OU_ADDR2"/>
                <fo:block/>
            </xsl:if>
            <xsl:if test="LE_ADDR3 !='' ">
                <xsl:value-of select="OU_ADDR3"/>
                <fo:block/>
            </xsl:if>
            <xsl:if test="OU_TOWN_CITY !=''">
                <xsl:value-of select="OU_TOWN_CITY"/>,
                <fo:leader leader-pattern="space" leader-length="2.0pt"/>

            <fo:block/>
            <xsl:value-of select="OU_COUNTRY"/>

Now, to your question:

how to compare two elements coming from xml as string

In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator = and the function not() together with the operator =.

$str1 = $str2

evaluates to true() exactly when the string $str1 is equal to the string $str2.

not($str1 = $str2)

evaluates to true() exactly when the string $str1 is not equal to the string $str2.

There is also the != operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.

Now, the rules for comparing two element nodes are similar:

$el1 = $el2

evaluates to true() exactly when the string value of $el1 is equal to the string value of $el2.

not($el1 = $el2)

evaluates to true() exactly when the string value of $el1 is not equal to the string value of $el2.

However, if one of the operands of = is a node-set, then

 $ns = $str

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string $str

$ns1 = $ns2

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string value of some node from $ns2

Therefore, the expression:

OU_NAME='OU_ADDR1'

evaluates to true() only when there is at least one element child of the current node that is named OU_NAME and whose string value is the string 'OU_ADDR1'.

This is obviously not what you want!

Most probably you want:

OU_NAME=OU_ADDR1

This expression evaluates to true exactly there is at least one OU_NAME child of the current node and one OU_ADDR1 child of the current node with the same string value.

Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt, le, eq, gt, ge and the inherited from XPath 1.0 general comparison operator =.

Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.

Why not one more answer? setState() and the setState()-triggered render() have both completed executing when you call componentDidMount() (the first time render() is executed) and/or componentDidUpdate() (any time after render() is executed). (Links are to ReactJS.org docs.)

Example with componentDidUpdate()

Caller, set reference and set state...

<Cmp ref={(inst) => {this.parent=inst}}>;
this.parent.setState({'data':'hello!'});

Render parent...

componentDidMount() {           // componentDidMount() gets called after first state set
    console.log(this.state.data);   // output: "hello!"
}
componentDidUpdate() {          // componentDidUpdate() gets called after all other states set
    console.log(this.state.data);   // output: "hello!"
}

Example with componentDidMount()

Caller, set reference and set state...

<Cmp ref={(inst) => {this.parent=inst}}>
this.parent.setState({'data':'hello!'});

Render parent...

render() {              // render() gets called anytime setState() is called
    return (
        <ChildComponent
            state={this.state}
        />
    );
}

After parent rerenders child, see state in componentDidUpdate().

componentDidMount() {           // componentDidMount() gets called anytime setState()/render() finish
console.log(this.props.state.data); // output: "hello!"
}

There is an almost imperceptible setting that fixed this issue for me. If there is a particular source file in which the breakpoint isn't hitting, it could be listed in

• Solution Explorer
  • right-click Solution
    • Properties
      • Common Properties
        • Debug Source Files
          • "Do not look for these source files".

For some reason unknown to me, VS 2013 decided to place a source file there, and subsequently, I couldn't hit breakpoint in that file anymore. This may be the culprit for "source code is different from the original version".

According to :https://anaconda.org/intel/tensorflow

To install this package with conda run:

conda install -c intel tensorflow

pip install To install this package with pip:

pip install -i https://pypi.anaconda.org/intel/simple tensorflow

Here is a bash script inspired by abarnert's answer which will unpack a package named MyPackage.pkg into a subfolder named MyPackage_pkg and then open the folder in Finder.

    #!/usr/bin/env bash
    filename="$*"
    dirname="${filename/\./_}"
    pkgutil --expand "$filename" "$dirname"
    cd "$dirname"
    tar xvf Payload
    open .

Usage:

    pkg-upack.sh MyPackage.pkg

Warning: This will not work in all cases, and will fail with certain files, e.g. the PKGs inside the OSX system installer. If you want to peek inside the pkg file and see what's inside, you can try SuspiciousPackage (free app), and if you need more options such as selectively unpacking specific files, then have a look at Pacifist (nagware).

Checking your linked site, you may include a script tag passing a ?var=desiredVarName parameter which will be set as a global variable containing the IP address:

<script type="text/javascript" src="http://l2.io/ip.js?var=myip"></script>
                                                      <!-- ^^^^ -->
<script>alert(myip);</script>

Demo

I believe I don't have to say that this can be easily spoofed (through either use of proxies or spoofed request headers), but it is worth noting in any case.

HTTPS support

In case your page is served using the https protocol, most browsers will block content in the same page served using the http protocol (that includes scripts and images), so the options are rather limited. If you have < 5k hits/day, the Smart IP API can be used. For instance:

<script>
var myip;
function ip_callback(o) {
    myip = o.host;
}
</script>
<script src="https://smart-ip.net/geoip-json?callback=ip_callback"></script>
<script>alert(myip);</script>

Demo

Edit: Apparently, this https service's certificate has expired so the user would have to add an exception manually. Open its API directly to check the certificate state: https://smart-ip.net/geoip-json

With back-end logic

The most resilient and simple way, in case you have back-end server logic, would be to simply output the requester's IP inside a <script> tag, this way you don't need to rely on external resources. For example:

PHP:

<script>var myip = '<?php echo $_SERVER['REMOTE_ADDR']; ?>';</script>

There's also a more sturdy PHP solution (accounting for headers that are sometimes set by proxies) in this related answer.

C#:

<script>var myip = '<%= Request.UserHostAddress %>';</script>

One risk of using the keyboard shortcut is that it requires using a non-ASCII encoding. That might be fine, but if your source is loaded by different editors in different locales, you might hit trouble somewhere along the line.

It might be safer to use either ’ or ’ (which are equivalent) as both are ASCII.

There is no difference between moving and renaming; you should simply call Directory.Move.

In general, if you're only doing a single operation, you should use the static methods in the File and Directory classes instead of creating FileInfo and DirectoryInfo objects.

Android has a mechanism in place to close an application safely per its documentation. In the last Activity that is exited (usually the main Activity that first came up when the application started) just place a couple of lines in the onDestroy() method. The call to System.runFinalizersOnExit(true) ensures that all objects will be finalized and garbage collected when the the application exits. You can also kill an application quickly via android.os.Process.killProcess(android.os.Process.myPid()) if you prefer. The best way to do this is put a method like the following in a helper class and then call it whenever the app needs to be killed. For example in the destroy method of the root activity (assuming that the app never kills this activity):

Also Android will not notify an application of the HOME key event, so you cannot close the application when the HOME key is pressed. Android reserves the HOME key event to itself so that a developer cannot prevent users from leaving their application. However you can determine with the HOME key is pressed by setting a flag to true in a helper class that assumes that the HOME key has been pressed, then changing the flag to false when an event occurs that shows the HOME key was not pressed and then checking to see of the HOME key pressed in the onStop() method of the activity.

Don't forget to handle the HOME key for any menus and in the activities that are started by the menus. The same goes for the SEARCH key. Below is some example classes to illustrate:

Here's an example of a root activity that kills the application when it is destroyed:

package android.example;

/**
 * @author Danny Remington - MacroSolve
 */

public class HomeKey extends CustomActivity {

    public void onDestroy() {
        super.onDestroy();

        /*
         * Kill application when the root activity is killed.
         */
        UIHelper.killApp(true);
    }

}

Here's an abstract activity that can be extended to handle the HOME key for all activities that extend it:

package android.example;

/**
 * @author Danny Remington - MacroSolve
 */

import android.app.Activity;
import android.view.Menu;
import android.view.MenuInflater;

/**
 * Activity that includes custom behavior shared across the application. For
 * example, bringing up a menu with the settings icon when the menu button is
 * pressed by the user and then starting the settings activity when the user

public abstract class CustomActivity extends Activity {
    public void onStart() {
        super.onStart();

        /*

         * navigated to this activity so the HOME key was not pressed.
         */

        UIHelper.checkJustLaunced();
    }

    public void finish() {
        /*
         * This can only invoked by the user or the app finishing the activity
         * by navigating from the activity so the HOME key was not pressed.
         */
        UIHelper.homeKeyPressed = false;
        super.finish();
    }

    public void onStop() {
        super.onStop();

        /*
         * Check if the HOME key was pressed. If the HOME key was pressed then
         * the app will be killed. Otherwise the user or the app is navigating
         * away from this activity so assume that the HOME key will be pressed
         * next unless a navigation event by the user or the app occurs.
         */
        UIHelper.checkHomeKeyPressed(true);
    }

    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.settings_menu, menu);

        /*
         * Assume that the HOME key will be pressed next unless a navigation
         * event by the user or the app occurs.
         */
        UIHelper.homeKeyPressed = true;

        return true;
    }

    public boolean onSearchRequested() {
        /*
         * Disable the SEARCH key.
         */
        return false;
    }
}

Here's an example of a menu screen that handles the HOME key:

/**
 * @author Danny Remington - MacroSolve
 */

package android.example;

import android.os.Bundle;
import android.preference.PreferenceActivity;

/**
 * PreferenceActivity for the settings screen.

        super.onStart();

        /*
         * This can only invoked by the user or the app starting the activity by
         * navigating to the activity so the HOME key was not pressed.

         * This can only invoked by the user or the app finishing the activity
         * by navigating from the activity so the HOME key was not pressed.
         */
        UIHelper.homeKeyPressed = false;
        super.finish();
    }

    public void onStop() {
        super.onStop();

        /*

        UIHelper.checkHomeKeyPressed(true);
    }

    public boolean onSearchRequested() {
        /*
         * Disable the SEARCH key.
         */
        return false;
    }

For now no jquery or php needed. Use just "required" HTML5 input attrbute like here

 <form>
        <p>
            <input class="form-control" type="text" name="email" />
            <input type="submit" value="ok" class="btn btn-success" name="submit" />
            <input type="hidden" name="action" value="0" />
        </p>
        <p><input type="checkbox" required name="terms">I have read and accept <a href="#">SOMETHING Terms and Conditions</a></p>
 </form>

This will validate and prevent any submit before checkbox is opt in. Language independent solution because its generated by users web browser.

Shutdown hooks execute in all cases where the VM is not forcibly killed. So, if you were to issue a "standard" kill (SIGTERM from a kill command) then they will execute. Similarly, they will execute after calling System.exit(int).

However a hard kill (kill -9 or kill -SIGKILL) then they won't execute. Similarly (and obviously) they won't execute if you pull the power from the computer, drop it into a vat of boiling lava, or beat the CPU into pieces with a sledgehammer. You probably already knew that, though.

Finalizers really should run as well, but it's best not to rely on that for shutdown cleanup, but rather rely on your shutdown hooks to stop things cleanly. And, as always, be careful with deadlocks (I've seen far too many shutdown hooks hang the entire process)!

You need to use a TimeSpan. Here is some sample code:

TimeSpan sincelast = TimeSpan.FromTicks(DateTime.Now.Ticks - LastUpdate.Ticks);

protected void switchTabsUsingPartOfUrl(String platform) {
    String currentHandle = null;
    try {
        final Set<String> handles = driver.getWindowHandles();
        if (handles.size() > 1) {
            currentHandle = driver.getWindowHandle();
        }
        if (currentHandle != null) {
            for (final String handle : handles) {
                driver.switchTo().window(handle);
                if (currentUrl().contains(platform) && !currentHandle.equals(handle)) {
                    break;
                }
            }
        } else {
            for (final String handle : handles) {
                driver.switchTo().window(handle);
                if (currentUrl().contains(platform)) {
                    break;
                }
            }
        }
    } catch (Exception e) {
        System.out.println("Switching tabs failed");
    }
}

Call this method and pass parameter a substring of url of the tab you want to switch to

To obtain a stream of just the names:

$ jq '.[] | select(.location=="Stockholm") | .name' json

produces:

"Donald"
"Walt"

To obtain a stream of corresponding (key name, "name" attribute) pairs, consider:

$ jq -c 'to_entries[]
        | select (.value.location == "Stockholm")
        | [.key, .value.name]' json

Output:

["FOO","Donald"]
["BAR","Walt"]

Iterator it = map.entrySet().iterator();
while (it.hasNext()) {
     Map.Entry pairs = (Map.Entry)it.next();

     if(pairs.getKey().equals("mango"))
     {
        map.put(pairs.getKey(), pairs.getValue().add(18));
     }

     else if(!map.containsKey("mango"))
     {
        List<Integer> ints = new ArrayList<Integer>();
        ints.add(18);
        map.put("mango",ints);
     }

     it.remove(); // avoids a ConcurrentModificationException
}

EDIT: So inside the while try this:

map.put(pairs.getKey(), pairs.getValue().add(number))

You are getting the error because you are trying to put an integer to the values, whereas it is expected an ArrayList.

EDIT 2: Then put the following inside your while loop:

if(pairs.getKey().equals("mango"))
{
    map.put(pairs.getKey(), pairs.getValue().add(18));
}

else if(!map.containsKey("mango"))
{
     List<Integer> ints = new ArrayList<Integer>();
     ints.add(18);
     map.put("mango",ints);
 }

EDIT 3: By reading your requirements, I come to think you may not need a loop. You may want to only check if the map contains the key mango, and if it does add 18, else create a new entry in the map with key mango and value 18.

So all you may need is the following, without the loop:

if(map.containsKey("mango"))
{
    map.put("mango", map.get("mango).add(18));
}

else
{
    List<Integer> ints = new ArrayList<Integer>();
    ints.add(18);
    map.put("mango", ints);
}

If you are dealing with older versions of .NET Framework, then support for TLS 1.2 is available in our SecureBlackbox product in both client and server components. SecureBlackbox contains its own implementation of all algorithms, so it doesn't matter which version of .NET-based framework you use (including .NET CF) - you'll have TLS 1.2 with the latest additions in all cases.

Please note that SecureBlackbox wont magically add TLS 1.2 to framework classes - instead you need to use SecureBlackbox classes and components explicitly.

In order to trap repeated clicks on the same cell, you need to move the focus to a different cell, so that each time you click, you are in fact moving the selection.

The code below will select the top left cell visible on the screen, when you click on any cell. Obviously, it has the flaw that it won't trap a click on the top left cell, but that can be managed (eg by selecting the top right cell if the activecell is the top left).

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  'put your code here to process the selection, then..
  ActiveWindow.VisibleRange.Cells(1, 1).Select

I just wanna add this, when you access the position of the array like

arg[n]

is the same as

*(arg + n) than means an offset of n starting from de arg address.

so arg[0] will be *arg

It is better if you don't kill a thread. A way could be to introduce a "try" block into the thread's cycle and to throw an exception when you want to stop the thread (for example a break/return/... that stops your for/while/...). I've used this on my app and it works...

The below snippet examines EAX using GDB.

    (gdb) info register eax
    eax            0xaa55   43605
    (gdb) info register ax
    ax             0xaa55   -21931
    (gdb) info register ah
    ah             0xaa -86
    (gdb) info register al
    al             0x55 85

1. EAX - Full 32 bit value
2. AX - lower 16 bit value
3. AH - Bits from 8 to 15
4. AL - lower 8 bits of EAX/AX

Uninstall jdk8, install jdk7, then reinstall jdk8.

My approach to switching between them (in .profile) :

export JAVA_7_HOME=$(/usr/libexec/java_home -v1.7)
export JAVA_8_HOME=$(/usr/libexec/java_home -v1.8)
export JAVA_9_HOME=$(/usr/libexec/java_home -v9)

alias java7='export JAVA_HOME=$JAVA_7_HOME'
alias java8='export JAVA_HOME=$JAVA_8_HOME'
alias java9='export JAVA_HOME=$JAVA_9_HOME'

#default java8
export JAVA_HOME=$JAVA_8_HOME

Then you can simply type java7 or java8 in a terminal to switch versions.

Following the @johannes solution, but merging without loosing data (it was missing first elements):

    Function mergeArrays(ByRef arr1() As Variant, arr2() As Variant) As Variant

    Dim returnThis() As Variant
    Dim len1 As Integer, len2 As Integer, lenRe As Integer, counter As Integer
    len1 = UBound(arr1)
    len2 = UBound(arr2)
    lenRe = len1 + len2 + 1
    ReDim returnThis(0 To lenRe)
    counter = 0

    For counter = 0 To len1 'get first array in returnThis
        returnThis(counter) = arr1(counter)
    Next


    For counter = 0 To len2 'get the second array in returnThis
        returnThis(counter + len1 + 1) = arr2(counter)
    Next
mergeArrays = returnThis
End Function

I think this link demonstrates the best way to get application context anywhere, even in the non-bean class. I find it very useful. Hope its the same for you. The below is the abstract code of it

Create a new class ApplicationContextProvider.java

package com.java2novice.spring;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class ApplicationContextProvider implements ApplicationContextAware{

    private static ApplicationContext context;

    public static ApplicationContext getApplicationContext() {
        return context;
    }

    @Override
    public void setApplicationContext(ApplicationContext ac)
            throws BeansException {
        context = ac;
    }
}

Add an entry in application-context.xml

<bean id="applicationContextProvider"
                        class="com.java2novice.spring.ApplicationContextProvider"/>

In annotations case (instead of application-context.xml)

@Component
public class ApplicationContextProvider implements ApplicationContextAware{

Get the context like this

TestBean tb = ApplicationContextProvider.getApplicationContext().getBean("testBean", TestBean.class);

Cheers!!

Your where clause should have worked. I am at a loss as to why it didn't. Let me show you how I would have figured out the problem with the where clause as it might help you for the future.

When I create triggers, I start at the query window by creating a temp table called #inserted (and or #deleted) with all the columns of the table. Then I popultae it with typical values (Always multiple records and I try to hit the test cases in the values)

Then I write my triggers logic and I can test without it actually being in a trigger. In a case like your where clause not doing what was expected, I could easily test by commenting out the insert to see what the select was returning. I would then probably be easily able to see what the problem was. I assure you that where clasues do work in triggers if they are written correctly.

Once I know that the code works properly for all the cases, I global replace #inserted with inserted and add the create trigger code around it and voila, a tested trigger.

AS I said in a comment, I have a concern that the solution you picked will not work properly in a multiple record insert or update. Triggers should always be written to account for that as you cannot predict if and when they will happen (and they do happen eventually to pretty much every table.)

w=open(file.txt, 'r')
print ('first line is : ',w.readline())
for line in w:  
    x= line
print ('last line is : ',x)
w.close()

The for loop runs through the lines and x gets the last line on the final iteration.

If you have Anaconda installed I recomend you to uninstall it and try installing python package from source, i fixed this problem in this way

Python 3.7: introduction of defaults param in namedtuple definition.

Example as shown in the documentation:

>>> Account = namedtuple('Account', ['type', 'balance'], defaults=[0])
>>> Account._fields_defaults
{'balance': 0}
>>> Account('premium')
Account(type='premium', balance=0)

Always safe to use either Comparator or Comparable interface to provide sorting implementation (if the object is not a String or Wrapper classes for primitive data types) . As an example for a comparator implementation to sort employees based on name

    List<Employees> empList = new LinkedList<Employees>(EmpSet);

    class EmployeeComparator implements Comparator<Employee> {

            public int compare(Employee e1, Employee e2) {
                return e1.getName().compareTo(e2.getName());
            }

        }

   Collections.sort(empList , new EmployeeComparator ());

Comparator is useful when you need to have different sorting algorithm on same object (Say emp name, emp salary, etc). Single mode sorting can be implemented by using Comparable interface in to the required object.

The server_name^docs directive is used to identify virtual hosts, they're not used to set the binding.

netstat tells you that nginx listens on 0.0.0.0:80 which means that it will accept connections from any IP.

If you want to change the IP nginx binds on, you have to change the listen^docs rule.
So, if you want to set nginx to bind to localhost, you'd change that to:

listen 127.0.0.1:80;

In this way, requests that are not coming from localhost are discarded (they don't even hit nginx).

Gensim implements a model called Doc2Vec for paragraph embedding.

There are different tutorials presented as IPython notebooks:

• Doc2Vec Tutorial on the Lee Dataset
• Gensim Doc2Vec Tutorial on the IMDB Sentiment Dataset
• Doc2Vec to wikipedia articles

Another method would rely on Word2Vec and Word Mover's Distance (WMD), as shown in this tutorial:

• Finding similar documents with Word2Vec and WMD

An alternative solution would be to rely on average vectors:

from gensim.models import KeyedVectors
from gensim.utils import simple_preprocess    

def tidy_sentence(sentence, vocabulary):
    return [word for word in simple_preprocess(sentence) if word in vocabulary]    

def compute_sentence_similarity(sentence_1, sentence_2, model_wv):
    vocabulary = set(model_wv.index2word)    
    tokens_1 = tidy_sentence(sentence_1, vocabulary)    
    tokens_2 = tidy_sentence(sentence_2, vocabulary)    
    return model_wv.n_similarity(tokens_1, tokens_2)

wv = KeyedVectors.load('model.wv', mmap='r')
sim = compute_sentence_similarity('this is a sentence', 'this is also a sentence', wv)
print(sim)

Finally, if you can run Tensorflow, you may try: https://tfhub.dev/google/universal-sentence-encoder/2

May use this-

#if defined CONDITION1 || defined CONDITION2
//your code here
#endif

This also does the same-

#if defined(CONDITION1) || defined(CONDITION2)
//your code here
#endif

Further-

• AND: #if defined CONDITION1 && defined CONDITION2
• XOR: #if defined CONDITION1 ^ defined CONDITION2
• AND NOT: #if defined CONDITION1 && !defined CONDITION2

You can directly use the S3 path. I am using Pandas 0.24.1

In [1]: import pandas as pd

In [2]: df = pd.DataFrame( [ [1, 1, 1], [2, 2, 2] ], columns=['a', 'b', 'c'])

In [3]: df
Out[3]:
   a  b  c
0  1  1  1
1  2  2  2

In [4]: df.to_csv('s3://experimental/playground/temp_csv/dummy.csv', index=False)

In [5]: pd.__version__
Out[5]: '0.24.1'

In [6]: new_df = pd.read_csv('s3://experimental/playground/temp_csv/dummy.csv')

In [7]: new_df
Out[7]:
   a  b  c
0  1  1  1
1  2  2  2

Release Note:

S3 File Handling

pandas now uses s3fs for handling S3 connections. This shouldn’t break any code. However, since s3fs is not a required dependency, you will need to install it separately, like boto in prior versions of pandas. GH11915.

I tried researching that too but instead ended up using jsconsole.com by Remy Sharp (he also created jsbin.com). I'm running on Ubuntu 12.10 so I had to create a special icon but if you're on Windows and use Chrome simply go to Tools>Create Application Shortcuts (note this doesn't work very well, or at all in my case, on Ubuntu). This site works very like the Mac jsc console: actually it has some cool features too (like loading libraries/code from a URL) that I guess jsc does not.

Hope this helps.

a = 0.000006;
b = 6;
c = a/b;

textbox.Text = c.ToString("0.000000");

As you requested:

textbox.Text = c.ToString("0.######");

This will only display out to the 6th decimal place if there are 6 decimals to display.

Building on @Andrew's solution, you'll get much better performance using a non-procedural table-valued-function and CROSS APPLY:

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
/*  Usage:
    SELECT t.[YourColumn], c.StringCount
    FROM YourDatabase.dbo.YourTable t
        CROSS APPLY dbo.CountOccurrencesOfString('your search string',     t.[YourColumn]) c
*/
CREATE FUNCTION [dbo].[CountOccurrencesOfString]
(
    @searchTerm nvarchar(max),
    @searchString nvarchar(max)

)
RETURNS TABLE
AS
    RETURN 
    SELECT (DATALENGTH(@searchString)-DATALENGTH(REPLACE(@searchString,@searchTerm,'')))/NULLIF(DATALENGTH(@searchTerm), 0) AS StringCount

Use the following command to get connected to your MySQL database

mysql -u USERNAME -h HOSTNAME -p

(This answer only applies to C# not C++, sorry I misread the original question)

I've got through DLL hell like this before. My final solution was to store the unmanaged DLLs in the managed DLL as binary resources, and extract them to a temporary folder when the program launches and delete them when it gets disposed.

This should be part of the .NET or pinvoke infrastructure, since it is so useful.... It makes your managed DLL easy to manage, both using Xcopy or as a Project reference in a bigger Visual Studio solution. Once you do this, you don't have to worry about post-build events.

UPDATE:

I posted code here in another answer https://stackoverflow.com/a/11038376/364818

Please be VERY careful with using the registry key approach. These are machine-wide keys and forcibily migrate ALL applications to .NET 4.0.

Many products do not work if forcibily migrated and this is a testing aid and not a production quality mechanism. Visual Studio 2008 and 2010, MSBuild, turbotax, and a host of websites, SharePoint and so on should not be automigrated.

If you need to use PowerShell with 4.0, this should be done on a per-application basis with a configuration file, you should check with the PowerShell team on the precise recommendation. This is likely to break some existing PowerShell commands.

No you can't - IP addresses get reallocated and reassigned from time to time, so the mapping of IP to location will also change over time.

If you want to find out the location that an IP address currently maps to you can either download a geolocation database, such as GeoLite from MaxMind, or use an API like http://ipinfo.io (my own service) which will also give you additional details:

$ curl ipinfo.io/8.8.8.8
{
  "ip": "8.8.8.8",
  "hostname": "google-public-dns-a.google.com",
  "loc": "37.385999999999996,-122.0838",
  "org": "AS15169 Google Inc.",
  "city": "Mountain View",
  "region": "California",
  "country": "US",
  "phone": 650
}

I had this problem and found that removing the following folder helped, even with the non-Express edition.Express:

C:\Users\<user>\Documents\IISExpress

How about this?

=IF(ISERROR(MATCH(A1,B:B, 0)), "No Match", INDIRECT(ADDRESS(MATCH(A1,B:B, 0), 3)))

The "3" at the end means for column C.

In my case, I had 2 forms in differents views and differents router files. The first router used the name field with view one and its file name was "inputGroupFile02". The second view had another name for file input. For some reason Multer not allows you set differents name in different views, so I dicided to use same name for the file input in both views.

Here is how I would do it in C++

size_t size = 500;
char* dynamicAllocatedString = new char[ size ];

Use same principal for any struct or c++ class.

I recently found out that :active:focus does the same thing in css as :active:hover if you need to override a custom css library, they might use both.

Restrictions

If you could send an SMS within a program on the iPhone, you'll be able to write games that spam people in the background. I'm sure you really want to have spams from your friends, "Try out this new game! It roxxers my boxxers, and yours will be too! roxxersboxxers.com!!!! If you sign up now you'll get 3,200 RB points!!"

Apple has restrictions for automated (or even partially automated) SMS and dialing operations. (Imagine if the game instead dialed 911 at a particular time of day)

Your best bet is to set up an intermediate server on the internet that uses an online SMS sending service and send the SMS via that route if you need complete automation. (ie, your program on the iPhone sends a UDP packet to your server, which sends the real SMS)

iOS 4 Update

iOS 4, however, now provides a viewController you can import into your application. You prepopulate the SMS fields, then the user can initiate the SMS send within the controller. Unlike using the "SMS:..." url format, this allows your application to stay open, and allows you to populate both the to and the body fields. You can even specify multiple recipients.

This prevents applications from sending automated SMS without the user explicitly aware of it. You still cannot send fully automated SMS from the iPhone itself, it requires some user interaction. But this at least allows you to populate everything, and avoids closing the application.

The MFMessageComposeViewController class is well documented, and tutorials show how easy it is to implement.

iOS 5 Update

iOS 5 includes messaging for iPod touch and iPad devices, so while I've not yet tested this myself, it may be that all iOS devices will be able to send SMS via MFMessageComposeViewController. If this is the case, then Apple is running an SMS server that sends messages on behalf of devices that don't have a cellular modem.

iOS 6 Update

No changes to this class.

iOS 7 Update

You can now check to see if the message medium you are using will accept a subject or attachments, and what kind of attachments it will accept. You can edit the subject and add attachments to the message, where the medium allows it.

iOS 8 Update

No changes to this class.

iOS 9 Update

No changes to this class.

iOS 10 Update

No changes to this class.

iOS 11 Update

No significant changes to this class

Limitations to this class

Keep in mind that this won't work on phones without iOS 4, and it won't work on the iPod touch or the iPad, except, perhaps, under iOS 5. You must either detect the device and iOS limitations prior to using this controller, or risk restricting your app to recently upgraded 3G, 3GS, and 4 iPhones.

However, an intermediate server that sends SMS will allow any and all of these iOS devices to send SMS as long as they have internet access, so it may still be a better solution for many applications. Alternately, use both, and only fall back to an online SMS service when the device doesn't support it.

Use an insert ... select query, and put the known values in the select:

insert into table1
select 'A string', 5, idTable2
from table2
where ...

First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local.

Another simple way is to use @reboot in your crontab. Read the cron manpage for details.

However, if you want to do things properly, in addition to adding a script to /etc/init.d you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d which creates a symlink from some of the /etc/rc* directories to your script. So, you'd need to do something like:

update-rc.d yourscriptname start 2

However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README has some details and further pointers.

One way to do this is to put both images in the HTML, inside a SPAN or DIV, you can hide the default either with CSS, or with JS on page load. Then you can toggle on click. Here is a similar example I am using to put left/down icons on a list:

$(document).ready(function(){
    $(".button").click(function () {
        $(this).children(".arrow").toggle();
            return false;
    });
});

<a href="#" class="button">
    <span class="arrow">
        <img src="/images/icons/left.png" alt="+" />
    </span>
    <span class="arrow" style="display: none;">
        <img src="/images/down.png" alt="-" />
    </span>
</a>

Check you have <meta charset="utf-8"> inside head block.

Div is a block element and span is an inline element and its width depends upon the content of it self where div does not

Setting null values can be done with np.nan:

import numpy as np
df.replace('-', np.nan)

Advantage is that df.last_valid_index() recognizes these as invalid.

In addition to Salvador Dali's answer:

on the server side don't forget that the data comes in base64 string format. It's important because in some programming languages you need to explisitely say that this string should be regarded as bytes not simple Unicode string.

Otherwise decoding won't work: the image will be saved but it will be an unreadable file.

uniq would be fooled by trailing spaces and tabs. In order to emulate how a human makes comparison, I am trimming all trailing spaces and tabs before comparison.

I think that the $!N; needs curly braces or else it continues, and that is the cause of infinite loop.

I have bash 5.0 and sed 4.7 in Ubuntu 20.10. The second one-liner did not work, at the character set match.

Three variations, first to eliminate adjacent repeat lines, second to eliminate repeat lines wherever they occur, third to eliminate all but the last instance of lines in file.

pastebin

# First line in a set of duplicate lines is kept, rest are deleted.
# Emulate human eyes on trailing spaces and tabs by trimming those.
# Use after norepeat() to dedupe blank lines.

dedupe() {
 sed -E '
  $!{
   N;
   s/[ \t]+$//;
   /^(.*)\n\1$/!P;
   D;
  }
 ';
}

# Delete duplicate, nonconsecutive lines from a file. Ignore blank
# lines. Trailing spaces and tabs are trimmed to humanize comparisons
# squeeze blank lines to one

norepeat() {
 sed -n -E '
  s/[ \t]+$//;
  G;
  /^(\n){2,}/d;
  /^([^\n]+).*\n\1(\n|$)/d;
  h;
  P;
  ';
}

lastrepeat() {
 sed -n -E '
  s/[ \t]+$//;
  /^$/{
   H;
   d;
  };
  G;
  # delete previous repeated line if found
  s/^([^\n]+)(.*)(\n\1(\n.*|$))/\1\2\4/;
  # after searching for previous repeat, move tested last line to end
  s/^([^\n]+)(\n)(.*)/\3\2\1/;
  $!{
   h;
   d;
  };
  # squeeze blank lines to one
  s/(\n){3,}/\n\n/g;
  s/^\n//;
  p;
 ';
}

Before starting you should stop the WAMP services, or at least restart the services when prompted to start them.

On the old server instance navigate to the MySQL data folder by default this should look something similar to C:\wamp\bin\mysql\mysql5.1.53\data\ where mysql5.1.53 will be the version number of the previously installed MySQL database.

Inside this folder you should see a few files and folders. The folders are the actual MySQL databases, and contain a bunch of .frm files which we will require. You should recognise the folder names as the database names. These folder and all their contents can be copied directly to your MySQL data folder, you can neglect the default databases mysql, performance_schema, test.

If you started the server now you will see the databases are picked up, however the databases will contain none of the tables which were copied across. In order for the contents of the database to be picked up, back in the data folder you should see a file ibdata1, this is the data file for tables, copy this directly into the data folder, you should already have a file in your new data folder called “ibdata1" so you may wish to rename this to ibdata1.bak before copying across the ibdata1 from the old MySQL data folder.

Once this has been done Restart all the WAMP services. You can use PhpMyAdmin to check if your databases have been successfully restored.

Fixed this without having to change anything related to TSL/SSL.

I was trying to see if the same thing was happening to pip, and saw that pip was broken. Did some digging and realized it's probably caused by Homebrew deleted python@2 on February 1st, 2020.

Running brew uninstall python@2 to delete python2 installed by Homebrew.

Destroyed the virtual env created using python3 and created a new one.
pip3 installing works fine again.

Using keySet-

id1.keySet().stream()
        .filter(x -> x == 1)
        .map(x -> id1.get(x))
        .collect(Collectors.toList())

Just read it in to MATLAB in one block

fid = fopen('file.csv');
data=textscan(fid,'%s %f %f','delimiter',',');
fclose(fid);

You can then process it using logical addressing

ind50 = data{2}>=50 ;

ind50 is then an index of the rows where column 2 is greater than 50. So

data{1}(ind50)

will list all the strings for the rows of interest. Then just use fprintf to write out your data to the new file

I think you can simple call like this, this will give you result value.

this.$route.query.page

Look image $route is object in Vue Instance and you can access with this keyword and next you can select object properties like above one :

Have a look Vue-router document for selecting queries value :

Vue Router Object

You could really, really, really optimize your code a lot by paying the price of creating the delegate only once (there's also no need to instantiate the class to call an static method). I've done something very similar, and I just cache a delegate to the "Run" method with the help of a helper class :-). It looks like this:

static class Indent{    
     public static void Run(){
         // implementation
     }
     // other helper methods
}

static class MacroRunner {

    static MacroRunner() {
        BuildMacroRunnerList();
    }

    static void BuildMacroRunnerList() {
        macroRunners = System.Reflection.Assembly.GetExecutingAssembly()
            .GetTypes()
            .Where(x => x.Namespace.ToUpper().Contains("MACRO"))
            .Select(t => (Action)Delegate.CreateDelegate(
                typeof(Action), 
                null, 
                t.GetMethod("Run", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public)))
            .ToList();
    }

    static List<Action> macroRunners;

    public static void Run() {
        foreach(var run in macroRunners)
            run();
    }
}

It is MUCH faster this way.

If your method signature is different from Action you could replace the type-casts and typeof from Action to any of the needed Action and Func generic types, or declare your Delegate and use it. My own implementation uses Func to pretty print objects:

static class PrettyPrinter {

    static PrettyPrinter() {
        BuildPrettyPrinterList();
    }

    static void BuildPrettyPrinterList() {
        printers = System.Reflection.Assembly.GetExecutingAssembly()
            .GetTypes()
            .Where(x => x.Name.EndsWith("PrettyPrinter"))
            .Select(t => (Func<object, string>)Delegate.CreateDelegate(
                typeof(Func<object, string>), 
                null, 
                t.GetMethod("Print", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public)))
            .ToList();
    }

    static List<Func<object, string>> printers;

    public static void Print(object obj) {
        foreach(var printer in printers)
            print(obj);
    }
}

On iOS 9.0.2, I'm getting the "register push notification alert" every time I delete the app and reinstall it. This is true for both AppStore production downloads and adhoc mode.

UPDATE: It is confirmed this is working for iOS 9.x

With Chrome and Safari you can add the CSS style -webkit-print-color-adjust: exact; to the element to force print the background color and/or image

You get the smallest and quickest loading production bundle by compiling with the Ahead of Time compiler, and tree-shake/minify with rollup as shown in the angular AOT cookbook here: https://angular.io/docs/ts/latest/cookbook/aot-compiler.html

This is also available with the Angular-CLI as said in previous answers, but if you haven't made your app using the CLI you should follow the cookbook.

I also have a working example with materials and SVG charts (backed by Angular2) that it includes a bundle created with the AOT cookbook. You also find all the config and scripts needed to create the bundle. Check it out here: https://github.com/fintechneo/angular2-templates/

I made a quick video demonstrating the difference between number of files and size of an AoT compiled build vs a development environment. It shows the project from the github repository above. You can see it here: https://youtu.be/ZoZDCgQwnmQ

Try this

var today = new Date()
var priorDate = new Date().setDate(today.getDate()-30)

As noted by @Neel, this method returns in Javascript Timestamp format. To convert it back to date object, you need to pass the above to a new Date object; new Date(priorDate).

The Below code make the bitmap perfectly with same size of the imageview. Get the bitmap image height and width and then calculate the new height and width with the help of imageview's parameters. That give you required image with best aspect ratio.

int currentBitmapWidth = bitMap.getWidth();
int currentBitmapHeight = bitMap.getHeight();

int ivWidth = imageView.getWidth();
int ivHeight = imageView.getHeight();
int newWidth = ivWidth;

newHeight = (int) Math.floor((double) currentBitmapHeight *( (double) new_width / (double) currentBitmapWidth));

Bitmap newbitMap = Bitmap.createScaledBitmap(bitMap, newWidth, newHeight, true);

imageView.setImageBitmap(newbitMap)

enjoy.

Use a SQL function (I'm the author):

• https://github.com/teopost/oracle-scripts/blob/master/fn_gen_inserts.sql

Usage:

select fn_gen_inserts('select * from tablename', 'p_new_owner_name', 'p_new_table_name')
from dual;

where:

p_sql            – dynamic query which will be used to export metadata rows
p_new_owner_name – owner name which will be used for generated INSERT
p_new_table_name – table name which will be used for generated INSERT

p_sql in this sample is 'select * from tablename'

You can find original source code here:

• http://dbaora.com/oracle-generate-rows-as-insert-statements-from-table-view-using-plsql/

Ashish Kumar's script generates individually usable insert statements instead of a SQL block, but supports fewer datatypes.

Not as complicated as it sounds.... Just leave the duplicate primary key out of your query.... this works for me !

I think it looks much cleaner then other proposed code.

I found it very useful to encode my URL to a safe one when I was returning a value through Ajax/PHP to a URL which was then read by the page again.

PHP output with URL encoder for the special character &:

// PHP returning the success information of an Ajax request
echo "".str_replace('&', '%26', $_POST['name']) . " category was changed";

// JavaScript sending the value to the URL
window.location.href = 'time.php?return=updated&val=' + msg;

// JavaScript/PHP executing the function printing the value of the URL,
// now with the text normally lost in space because of the reserved & character.

setTimeout("infoApp('updated','<?php echo $_GET['val'];?>');", 360);

By default it's logged into system log at /var/log/syslog, so it can be read by:

tail -f /var/log/syslog

If the file doesn't exist, check /etc/syslog.conf to see configuration file for syslogd. Note that the configuration file could be different, so check the running process if it's using different file:

# ps wuax | grep syslog
root      /sbin/syslogd -f /etc/syslog-knoppix.conf

^{Note: In some distributions (such as Knoppix) all logged messages could be sent into different terminal (e.g. /dev/tty12), so to access e.g. tty12 try pressing Control+Alt+F12.}

You can also use lsof tool to find out which log file the syslogd process is using, e.g.

sudo lsof -p $(pgrep syslog) | grep log$ 

To send the test message to syslogd in shell, you may try:

echo test | logger

For troubleshooting use a trace tool (strace on Linux, dtruss on Unix), e.g.:

sudo strace -fp $(cat /var/run/syslogd.pid)

This is how you do it column-wise:

[df[col].update((df[col] - df[col].min()) / (df[col].max() - df[col].min())) for col in df.columns]

Here's a lazy one-liner, also using itertools:

from itertools import compress, product

def combinations(items):
    return ( set(compress(items,mask)) for mask in product(*[[0,1]]*len(items)) )
    # alternative:                      ...in product([0,1], repeat=len(items)) )

Main idea behind this answer: there are 2^N combinations -- same as the number of binary strings of length N. For each binary string, you pick all elements corresponding to a "1".

items=abc * mask=###
 |
 V
000 -> 
001 ->   c
010 ->  b
011 ->  bc
100 -> a
101 -> a c
110 -> ab
111 -> abc

Things to consider:

• This requires that you can call len(...) on items (workaround: if items is something like an iterable like a generator, turn it into a list first with items=list(_itemsArg))
• This requires that the order of iteration on items is not random (workaround: don't be insane)
• This requires that the items are unique, or else {2,2,1} and {2,1,1} will both collapse to {2,1} (workaround: use collections.Counter as a drop-in replacement for set; it's basically a multiset... though you may need to later use tuple(sorted(Counter(...).elements())) if you need it to be hashable)

Demo

>>> list(combinations(range(4)))
[set(), {3}, {2}, {2, 3}, {1}, {1, 3}, {1, 2}, {1, 2, 3}, {0}, {0, 3}, {0, 2}, {0, 2, 3}, {0, 1}, {0, 1, 3}, {0, 1, 2}, {0, 1, 2, 3}]

>>> list(combinations('abcd'))
[set(), {'d'}, {'c'}, {'c', 'd'}, {'b'}, {'b', 'd'}, {'c', 'b'}, {'c', 'b', 'd'}, {'a'}, {'a', 'd'}, {'a', 'c'}, {'a', 'c', 'd'}, {'a', 'b'}, {'a', 'b', 'd'}, {'a', 'c', 'b'}, {'a', 'c', 'b', 'd'}]

Your classes should look like this

[XmlRoot("StepList")]
public class StepList
{
    [XmlElement("Step")]
    public List<Step> Steps { get; set; }
}

public class Step
{
    [XmlElement("Name")]
    public string Name { get; set; }
    [XmlElement("Desc")]
    public string Desc { get; set; }
}

Here is my testcode.

string testData = @"<StepList>
                        <Step>
                            <Name>Name1</Name>
                            <Desc>Desc1</Desc>
                        </Step>
                        <Step>
                            <Name>Name2</Name>
                            <Desc>Desc2</Desc>
                        </Step>
                    </StepList>";

XmlSerializer serializer = new XmlSerializer(typeof(StepList));
using (TextReader reader = new StringReader(testData))
{
    StepList result = (StepList) serializer.Deserialize(reader);
}

If you want to read a text file you should load the file into a FileStream and deserialize this.

using (FileStream fileStream = new FileStream("<PathToYourFile>", FileMode.Open)) 
{
    StepList result = (StepList) serializer.Deserialize(fileStream);
}

Arrays in Java have a fixed length that cannot be changed. So Java provides classes that allow you to maintain lists of variable length.

Generally, there is the List<T> interface, which represents a list of instances of the class T. The easiest and most widely used implementation is the ArrayList. Here is an example:

List<String> words = new ArrayList<String>();
words.add("Hello");
words.add("World");
words.add("!");

List.add() simply appends an element to the list and you can get the size of a list using List.size().

I wrote the following method which works for me.

protected bool isDirectoryFound(string path, string pattern)
    {
        bool success = false;

        DirectoryInfo directories = new DirectoryInfo(@path);
        DirectoryInfo[] folderList = directories.GetDirectories();

        Regex rx = new Regex(pattern);

        foreach (DirectoryInfo di in folderList)
        {
            if (rx.IsMatch(di.Name))
            {
                success = true;
                break;
            }
        }

        return success;
    }

The lines most pertinent to your question being:

DirectoryInfo directories = new DirectoryInfo(@path); DirectoryInfo[] folderList = directories.GetDirectories();

If you have set public access for bucket and if it is still not working, edit bucker policy and paste following:

    {
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "s3:PutObject",
                "s3:PutObjectAcl",
                "s3:GetObject",
                "s3:GetObjectAcl",
                "s3:DeleteObject"
            ],
            "Resource": [
                "arn:aws:s3:::yourbucketnamehere",
                "arn:aws:s3:::yourbucketnamehere/*"
            ],
            "Effect": "Allow",
            "Principal": "*"
        }
    ]
}

Some operations are quicker than java heap space manager. Delaying operations for some time can free memory space. You can use this method to escape heap size error:

waitForGarbageCollector(new Runnable() {
  @Override
  public void run() {
    // Your operations.
  }
});

/**
 * Measure used memory and give garbage collector time to free up some
 * of the space.
 *
 * @param callback Callback operations to be done when memory is free.
 */
public static void waitForGarbageCollector(final Runnable callback) {

  Runtime runtime;
  long maxMemory;
  long usedMemory;
  double availableMemoryPercentage = 1.0;
  final double MIN_AVAILABLE_MEMORY_PERCENTAGE = 0.1;
  final int DELAY_TIME = 5 * 1000;

  runtime =
    Runtime.getRuntime();

  maxMemory =
    runtime.maxMemory();

  usedMemory =
    runtime.totalMemory() -
    runtime.freeMemory();

  availableMemoryPercentage =
    1 -
    (double) usedMemory /
    maxMemory;

  if (availableMemoryPercentage < MIN_AVAILABLE_MEMORY_PERCENTAGE) {
    try {
      Thread.sleep(DELAY_TIME);
    } catch (InterruptedException e) {
      e.printStackTrace();
    }
    waitForGarbageCollector(
      callback);
  } else {
    // Memory resources are available, go to next operation:
    callback.run();
  }
}

The two approaches are not interchangeable. You should initialize state in the constructor when using ES6 classes, and define the getInitialState method when using React.createClass.

See the official React doc on the subject of ES6 classes.

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = { /* initial state */ };
  }
}

is equivalent to

var MyComponent = React.createClass({
  getInitialState() {
    return { /* initial state */ };
  },
});

I'm late answering this, but there's not one reasonable answer to date, despite being a popular question with highly upvoted answers....

Best practice: forward declaration headers

As illustrated by the Standard library's <iosfwd> header, the proper way to provide forward declarations for others is to have a forward declaration header. For example:

a.fwd.h:

#pragma once
class A;

a.h:

#pragma once
#include "a.fwd.h"
#include "b.fwd.h"

class A
{
  public:
    void f(B*);
};

b.fwd.h:

#pragma once
class B;

b.h:

#pragma once
#include "b.fwd.h"
#include "a.fwd.h"

class B
{
  public:
    void f(A*);
};

The maintainers of the A and B libraries should each be responsible for keeping their forward declaration headers in sync with their headers and implementation files, so - for example - if the maintainer of "B" comes along and rewrites the code to be...

b.fwd.h:

template <typename T> class Basic_B;
typedef Basic_B<char> B;

b.h:

template <typename T>
class Basic_B
{
    ...class definition...
};
typedef Basic_B<char> B;

...then recompilation of the code for "A" will be triggered by the changes to the included b.fwd.h and should complete cleanly.

Poor but common practice: forward declare stuff in other libs

Say - instead of using a forward declaration header as explained above - code in a.h or a.cc instead forward-declares class B; itself:

• if a.h or a.cc did include b.h later:
  • compilation of A will terminate with an error once it gets to the conflicting declaration/definition of B (i.e. the above change to B broke A and any other clients abusing forward declarations, instead of working transparently).
• otherwise (if A didn't eventually include b.h - possible if A just stores/passes around Bs by pointer and/or reference)
  • build tools relying on #include analysis and changed file timestamps won't rebuild A (and its further-dependent code) after the change to B, causing errors at link time or run time. If B is distributed as a runtime loaded DLL, code in "A" may fail to find the differently-mangled symbols at runtime, which may or may not be handled well enough to trigger orderly shutdown or acceptably reduced functionality.

If A's code has template specialisations / "traits" for the old B, they won't take effect.

If you select two files in IntellijIdea and press Ctrl + Dthen it will show you the diff. I use Ultimate and don't know if it will work with Community edition.

use DateTime.Now

try this:

DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")

Well best option is %java_home%\bin\xjc -p [your namespace] [xsd_file].xsd.

I also have a question if we have an option to do reverse engineering here. if yes can we generate xsd from pojo class?

if you dont wanna use DISTINCT use GROUP BY

 SELECT * FROM myTABLE GROUP BY EmailAddress

Based on the same basic idea as in @Will Hartung's answer, here is my magic one-tag extensible template engine. It even includes documentation and an example :-)

WEB-INF/tags/block.tag:

<%--
    The block tag implements a basic but useful extensible template system.

    A base template consists of a block tag without a 'template' attribute.
    The template body is specified in a standard jsp:body tag, which can
    contain EL, JSTL tags, nested block tags and other custom tags, but
    cannot contain scriptlets (scriptlets are allowed in the template file,
    but only outside of the body and attribute tags). Templates can be
    full-page templates, or smaller blocks of markup included within a page.

    The template is customizable by referencing named attributes within
    the body (via EL). Attribute values can then be set either as attributes
    of the block tag element itself (convenient for short values), or by
    using nested jsp:attribute elements (better for entire blocks of markup).

    Rendering a template block or extending it in a child template is then
    just a matter of invoking the block tag with the 'template' attribute set
    to the desired template name, and overriding template-specific attributes
    as necessary to customize it.

    Attribute values set when rendering a tag override those set in the template
    definition, which override those set in its parent template definition, etc.
    The attributes that are set in the base template are thus effectively used
    as defaults. Attributes that are not set anywhere are treated as empty.

    Internally, attributes are passed from child to parent via request-scope
    attributes, which are removed when rendering is complete.

    Here's a contrived example:

    ====== WEB-INF/tags/block.tag (the template engine tag)

    <the file you're looking at right now>

    ====== WEB-INF/templates/base.jsp (base template)

            ${moreStyle}

        <jsp:attribute name="footer">
            <div class="footer">
