Instead of choosing Restore Database..., select Restore Files and Filegroups...

Then enter a database name, select your .bak file path as the source, check the restore checkbox, and click Ok. If the .bak file is valid, it will work.

(The SQL Server restore option names are not intuitive for what should a very simple task.)

Restoring a Database from Backup

sql-server-->connect to instance-->Databases-->right-click on databases-->Restore
            DataBase..-->Device-->Add-->choose the path_filename(.bak)-->click OK

I had this error once, after running mysqldump on Windows PowerShell like so:

mysqldump -u root p my_db --no-data --no-create-db --no-create-info --routines --triggers --skip-opt --set-gtid-purged=OFF > db_objects.sql

What I did was change it to this (pipe instead to Set-Content):

mysqldump -u root p my_db --no-data --no-create-db --no-create-info --routines --triggers --skip-opt --set-gtid-purged=OFF | Set-Content db_objects.sql

And the problem went away!

Yes, it is possible. The steps are:

1. First Put the .mdf and .ldf file in C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\ folder

2. Then go to sql software , Right-click “Databases” and click the “Attach” option to open the Attach Databases dialog box

3. Click the “Add” button to open and Locate Database Files From C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\folder

4. Click the "OK" button. SQL Server Management Studio loads the database from the .MDF file.

The problem with your attempt at the psql command line is the direction of the slashes:

newTestDB-# /i E:\db-rbl-restore-20120511_Dump-20120514.sql   # incorrect
newTestDB-# \i E:/db-rbl-restore-20120511_Dump-20120514.sql   # correct

To be clear, psql commands start with a backslash, so you should have put \i instead. What happened as a result of your typo is that psql ignored everything until finding the first \, which happened to be followed by db, and \db happens to be the psql command for listing table spaces, hence why the output was a List of tablespaces. It was not a listing of "default tables of PostgreSQL" as you said.

Further, it seems that psql expects the filepath argument to delimit directories using the forward slash regardless of OS (thus on Windows this would be counter-intuitive).

It is worth noting that your attempt at "elevating permissions" had no relation to the outcome of the command you attempted to execute. Also, you did not say what caused the supposed "Permission Denied" error.

Finally, the extension on the dump file does not matter, in fact you don't even need an extension. Indeed, pgAdmin suggests a .backup extension when selecting a backup filename, but you can actually make it whatever you want, again, including having no extension at all. The problem is that pgAdmin seems to only allow a "Restore" of "Custom or tar" or "Directory" dumps (at least this is the case in the MAC OS X version of the app), so just use the psql \i command as shown above.

The GUI can be fickle at times. The error you got when using T-SQL is because you're trying to overwrite an existing database, but did not specify to overwrite/replace the existing database. The following might work:

Use Master
Go
RESTORE DATABASE Publications
  FROM DISK = 'C:\Publications_backup_2012_10_15_010004_5648316.bak'
  WITH 
    MOVE 'Publications' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS2008R2\MSSQL\DATA\Publications.mdf',--adjust path
    MOVE 'Publications_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS2008R2\MSSQL\DATA\Publications.ldf'
, REPLACE -- Add REPLACE to specify the existing database which should be overwritten.

There are some funnies restoring old databases into SQL 2008 via the guy; have you tried doing it via TSQL ?

Use Master
Go
RESTORE DATABASE YourDB
FROM DISK = 'C:\YourBackUpFile.bak'
WITH MOVE 'YourMDFLogicalName' TO 'D:\Data\YourMDFFile.mdf',--check and adjust path
MOVE 'YourLDFLogicalName' TO 'D:\Data\YourLDFFile.ldf'

This request displays all active requests and all those requests that explicitly block active requests.

All these and other useful scripts are implemented as representations in the SRV database, which is distributed freely. For example, the first script came from the view [inf].[vBigQuery], and the second came from view [inf].[vRequests].

There are also various third-party solutions for query history. I use Query Manager from Dbeaver: and Query Execution History from SQL Tools, which is embedded in SSMS:

There are two ways of doing this.

Most of the answers have correctly pointed out that style.display has no value called "hidden". It should be none.

If you want to use "hidden" the syntax should be as follows.

object.style.visibility="hidden"

The difference between the two is the visibility="hidden" property will only hide the contents of you element but retain it position on the page. Whereas the display ="none" will hide your complete element and the rest of the elements on the page will fill that void created by it.

Check this illustration

If you're testing/debugging a bash script, and simply want to skip forwards past one or more sections of code, here is a very simple way to do it that is also very easy to find and remove later (unlike most of the methods described above).

#!/bin/bash

echo "Run this"

cat >/dev/null <<GOTO_1

echo "Don't run this"

GOTO_1

echo "Also run this"

cat >/dev/null <<GOTO_2

echo "Don't run this either"

GOTO_2

echo "Yet more code I want to run"

To put your script back to normal, just delete any lines with GOTO.

We can also prettify this solution, by adding a goto command as an alias:

#!/bin/bash

shopt -s expand_aliases
alias goto="cat >/dev/null <<"

goto GOTO_1

echo "Don't run this"

GOTO_1

echo "Run this"

goto GOTO_2

echo "Don't run this either"

GOTO_2

echo "All done"

Aliases don't usually work in bash scripts, so we need the shopt command to fix that.

If you want to be able to enable/disable your goto's, we need a little bit more:

#!/bin/bash

shopt -s expand_aliases
if [ -n "$DEBUG" ] ; then
  alias goto="cat >/dev/null <<"
else
  alias goto=":"
fi

goto '#GOTO_1'

echo "Don't run this"

#GOTO1

echo "Run this"

goto '#GOTO_2'

echo "Don't run this either"

#GOTO_2

echo "All done"

Then you can do export DEBUG=TRUE before running the script.

The labels are comments, so won't cause syntax errors if disable our goto's (by setting goto to the ':' no-op), but this means we need to quote them in our goto statements.

Whenever using any kind of goto solution, you need to be careful that the code you're jumping past doesn't set any variables that you rely on later - you may need to move those definitions to the top of your script, or just above one of your goto statements.

1. Go to working directory where you project folder (cloned folder) is placed.
2. Now delete the folder.
3. in windows just right click and do delete.
4. in command line use rm -r "folder name"
5. this worked for me

For cases where you may be moving the tabs, here is some code.

for ( UINavigationController *controller in self.tabBarController.viewControllers ) {
            if ( [[controller.childViewControllers objectAtIndex:0] isKindOfClass:[MyViewController class]]) {
                [self.tabBarController setSelectedViewController:controller];
                break;
            }
        }

Subsetting the data and combining them back is unnecessary. So are loops since those operations are vectorized. From your previous edit, I'm guessing you are doing all of this to make bubble plots. If that is correct, perhaps the example below will help you. If this is way off, I can just delete the answer.

library(ggplot2)
# let's look at the included dataset named trees.
# ?trees for a description
data(trees)
ggplot(trees,aes(Height,Volume)) + geom_point(aes(size=Girth))
# Great, now how do we color the bubbles by groups?
# For this example, I'll divide Volume into three groups: lo, med, high
trees$set[trees$Volume<=22.7]="lo"
trees$set[trees$Volume>22.7 & trees$Volume<=45.4]="med"
trees$set[trees$Volume>45.4]="high"

ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth))


# Instead of just circles scaled by Girth, let's also change the symbol
ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth,pch=set))

# Now let's choose a specific symbol for each set. Full list of symbols at ?pch
trees$symbol[trees$Volume<=22.7]=1
trees$symbol[trees$Volume>22.7 & trees$Volume<=45.4]=2
trees$symbol[trees$Volume>45.4]=3

ggplot(trees,aes(Height,Volume,colour=set)) + geom_point(aes(size=Girth,pch=symbol))

The most secure way (in terms of special character and data type handling) is using json_encode():

var spge = <?php echo json_encode($cname); ?>;

For excellent code-readability, Fest Assertions has nice support for asserting lists

So in this case, something like:

Assertions.assertThat(returnedComponents).containsExactly("One", "Two", "Three");

Or make the expected list to an array, but I prefer the above approach because it's more clear.

Assertions.assertThat(returnedComponents).containsExactly(argumentComponents.toArray());

SELECT COUNT(*)
FROM `gd`
GROUP BY gid
HAVING COUNT(gid) > 10
ORDER BY lastupdated DESC;

EDIT (if you just want the gids):

SELECT MIN(gid)
FROM `gd`
GROUP BY gid
HAVING COUNT(gid) > 10
ORDER BY lastupdated DESC

Sometimes you just need to recreate new device

You need to add a name attribute to your dropdown list, then you need to add a required attribute, and then you can reference the error using myForm.[input name].$error.required:

HTML:

        <form name="myForm" ng-controller="Ctrl" ng-submit="save(myForm)" novalidate>
        <input type="text" name="txtServiceName" ng-model="ServiceName" required>
<span ng-show="myForm.txtServiceName.$error.required">Enter Service Name</span>
<br/>
          <select name="service_id" class="Sitedropdown" style="width: 220px;"          
                  ng-model="ServiceID" 
                  ng-options="service.ServiceID as service.ServiceName for service in services"
                  required> 
            <option value="">Select Service</option> 
          </select> 
          <span ng-show="myForm.service_id.$error.required">Select service</span>

        </form>

    Controller:

        function Ctrl($scope) {
          $scope.services = [
            {ServiceID: 1, ServiceName: 'Service1'},
            {ServiceID: 2, ServiceName: 'Service2'},
            {ServiceID: 3, ServiceName: 'Service3'}
          ];

    $scope.save = function(myForm) {
    console.log('Selected Value: '+ myForm.service_id.$modelValue);
    alert('Data Saved! without validate');
    };
        }

Here's a working plunker.

Lot of concepts here which will be useful:

List<Object> list = new ArrayList<Object>(Arrays.asList(new String[]{"Java","is","cool"}));
String[] a = new String[list.size()];
list.toArray(a);

Tip to print array of Strings:

System.out.println(Arrays.toString(a));

Do this:

box-shadow: 0 4px 2px -2px gray;

It's actually much simpler, whatever you set the blur to (3rd value), set the spread (4th value) to the negative of it.

I am using php 5.6 on window 10 with zend 1.12 version for me adding

require_once 'PHPUnit/Autoload.php';

before

abstract class Zend_Test_PHPUnit_ControllerTestCase extends PHPUnit_Framework_TestCase

worked. We need to add this above statement in ControllerTestCase.php file

app.run(use_reloader=True)

we can use this, use_reloader so every time we reload the page our code changes will be updated.

I found superagent to be really useful, it is very simple for example

const superagent=require('superagent')
superagent
.get('google.com')
.set('Authorization','Authorization object')
.set('Accept','application/json')

select date_format(str_to_date('31/12/2010', '%d/%m/%Y'), '%Y%m'); 

or

select date_format(str_to_date('12/31/2011', '%m/%d/%Y'), '%Y%m'); 

hard to tell from your example

Something like Nigel Cohen's would work if you were adding data to a copy of the collected set of form data:

form = FormType(request.POST)
if request.method == "POST":
    formcopy = form(request.POST.copy())
    formcopy.data['Email'] = GetEmailString()

just in case this is relevant for someone. I got the exact same error using ASP.NET and C# in Visual studio. When I started the app from within the visual studio it worked, but I got this issue. In the meantime, it turned out, that the path to my project contained the character "#" (c:\C#\testapplication). This seems to confuse IIS Express (maybe also IIS) and causes this issue. I guess "#" is a reserved character somewhere in ASP.NET or below. Changing the path helped and now it works as expected.

On the client side you can add and remove websites to be displayed in Compatibility View from Compatibility View Settings window of IE:

Are you sure it's compiling as C++? Check your file name (it should end in .cpp). Check your project settings.

There's simply nothing wrong with your program, and cout is in namespace std. Your installation of VS 2010 Beta 2 is defective, and I don't think it's just your installation.

I don't think VS 2010 is ready for C++ yet. The standard "Hello, World" program didn't work on Beta 1. I just tried creating a test Win32 console application, and the generated test.cpp file didn't have a main() function.

I've got a really, really bad feeling about VS 2010.

Use filter, or if the number of dictionaries in exampleSet is too high, use ifilter of the itertools module. It would return an iterator, instead of filling up your system's memory with the entire list at once:

from itertools import ifilter
for elem in ifilter(lambda x: x['type'] in keyValList, exampleSet):
    print elem

When the result is success but you get the "<" character, it means that some PHP error is returned.

If you want to see all message, you could get the result as a success response getting by the following:

success: function(response){
     var out = "";
     for(var i = 0; i < response.length; i++) {
        out += response[i];
     }
     alert(out) ;
},

It is possible to redirect from an iframe, but not to get information from the parent.

Product "Clean" was the solution for me.

In my case this error occurred with dot net core and Microsoft.Data.SqlClient. The solution was to add ;TrustServerCertificate=true to the end of the connection string.

(Update: If I could delete this answer I would, although since it's accepted, I can't. I'm updating the description to provide better guidance and discourage folks from using the poor practice I outlined in the original answer).

You can specify these parameters via context or environment parameters, such as in context.xml. See the sections titled "Context Parameters" and "Environment Entries" on this page:

http://tomcat.apache.org/tomcat-5.5-doc/config/context.html

As @netjeff points out, these values will be available via the Context.lookup(String) method and not as System parameters.

Another way to do specify these values is to define variables inside of the web.xml file of the web application you're deploying (see below). As @Roberto Lo Giacco points out, this is generally considered a poor practice since a deployed artifact should not be environment specific. However, below is the configuration snippet if you really want to do this:

<env-entry>
    <env-entry-name>SMTP_PASSWORD</env-entry-name>
    <env-entry-type>java.lang.String</env-entry-type>
    <env-entry-value>abc123ftw</env-entry-value>
</env-entry>

Another way to continue with the example @nfreeze used is this validation method:

UserModel.schema.path('name').validate(function (value, res) {
    UserModel.findOne({name: value}, 'id', function(err, user) {
        if (err) return res(err);
        if (user) return res(false);
        res(true);
    });
}, 'already exists');

For ASP.NET Core you'll need to spell it out:

@($"{Context.Request.Scheme}://{Context.Request.Host}{Context.Request.Path}{Context.Request.QueryString}")

Or you can add a using statement to your view:

@using Microsoft.AspNetCore.Http.Extensions

then

@Context.Request.GetDisplayUrl()

The _ViewImports.cshtml might be a better place for that @using

In Python 3, we use the bytes object, also known as str in Python 2.

# Python 3
key = bytes([0x13, 0x00, 0x00, 0x00, 0x08, 0x00])

# Python 2
key = ''.join(chr(x) for x in [0x13, 0x00, 0x00, 0x00, 0x08, 0x00])

I find it more convenient to use the base64 module...

# Python 3
key = base64.b16decode(b'130000000800')

# Python 2
key = base64.b16decode('130000000800')

You can also use literals...

# Python 3
key = b'\x13\0\0\0\x08\0'

# Python 2
key = '\x13\0\0\0\x08\0'

You can just add objects of diffefent "Types" to an instance of ArrayList. No need create an ArrayList. Have a look at the below example, You will get below output:

Beginning....
Contents of array: [String, 1]
Size of the list: 2
This is not an Integer String
This is an Integer 1

package com.viswa.examples.programs;

import java.util.ArrayList;
import java.util.Arrays;

public class VarArrayListDemo {

    @SuppressWarnings({ "rawtypes", "unchecked" })
    public static void main(String[] args) {
        System.out.println(" Beginning....");

        ArrayList varTypeArray = new ArrayList();
        varTypeArray.add("String");
        varTypeArray.add(1); //Stored as Integer

        System.out.println(" Contents of array: " + varTypeArray + "\n Size of the list: " + varTypeArray.size());

        Arrays.stream(varTypeArray.toArray()).forEach(VarArrayListDemo::checkType);
    }

    private static <T> void checkType(T t) {

        if (Integer.class.isInstance(t)) {
            System.out.println(" This is an Integer " + t);
        } else {
            System.out.println(" This is not an Integer" + t);
        }
    }

Event listeners

First off it's important to understand that there are two kinds of "event listeners":

1. Scope event listeners registered via $on:

   $scope.$on('anEvent', function (event, data) {
     ...
   });
   

2. Event handlers attached to elements via for example on or bind:

   element.on('click', function (event) {
     ...
   });
   

$scope.$destroy()

When $scope.$destroy() is executed it will remove all listeners registered via $on on that $scope.

It will not remove DOM elements or any attached event handlers of the second kind.

This means that calling $scope.$destroy() manually from example within a directive's link function will not remove a handler attached via for example element.on, nor the DOM element itself.

element.remove()

Note that remove is a jqLite method (or a jQuery method if jQuery is loaded before AngularjS) and is not available on a standard DOM Element Object.

When element.remove() is executed that element and all of its children will be removed from the DOM together will all event handlers attached via for example element.on.

It will not destroy the $scope associated with the element.

To make it more confusing there is also a jQuery event called $destroy. Sometimes when working with third-party jQuery libraries that remove elements, or if you remove them manually, you might need to perform clean up when that happens:

element.on('$destroy', function () {
  scope.$destroy();
});

What to do when a directive is "destroyed"

This depends on how the directive is "destroyed".

A normal case is that a directive is destroyed because ng-view changes the current view. When this happens the ng-view directive will destroy the associated $scope, sever all the references to its parent scope and call remove() on the element.

This means that if that view contains a directive with this in its link function when it's destroyed by ng-view:

scope.$on('anEvent', function () {
 ...
});

element.on('click', function () {
 ...
});

Both event listeners will be removed automatically.

However, it's important to note that the code inside these listeners can still cause memory leaks, for example if you have achieved the common JS memory leak pattern circular references.

Even in this normal case of a directive getting destroyed due to a view changing there are things you might need to manually clean up.

For example if you have registered a listener on $rootScope:

var unregisterFn = $rootScope.$on('anEvent', function () {});

scope.$on('$destroy', unregisterFn);

This is needed since $rootScope is never destroyed during the lifetime of the application.

The same goes if you are using another pub/sub implementation that doesn't automatically perform the necessary cleanup when the $scope is destroyed, or if your directive passes callbacks to services.

Another situation would be to cancel $interval/$timeout:

var promise = $interval(function () {}, 1000);

scope.$on('$destroy', function () {
  $interval.cancel(promise);
});

If your directive attaches event handlers to elements for example outside the current view, you need to manually clean those up as well:

var windowClick = function () {
   ...
};

angular.element(window).on('click', windowClick);

scope.$on('$destroy', function () {
  angular.element(window).off('click', windowClick);
});

These were some examples of what to do when directives are "destroyed" by Angular, for example by ng-view or ng-if.

If you have custom directives that manage the lifecycle of DOM elements etc. it will of course get more complex.

2020 Updated Answer

It is 2020 (7 years later) and I have learned more about Linux during this time. Specifically that it might not be a good idea to run sudo make install when installing libraries, as these may interfere with the package management system. (In this case apt as I am using Debian 10.)

If this is not correct, please correct me in the comments.

Alternative proposed solution

This information is taken from the GLFW docs, however I have expanded/streamlined the information which is relevant to Linux users.

• Go to home directory and clone glfw repository from github

cd ~
git clone https://github.com/glfw/glfw.git
cd glfw

• You can at this point create a build directory and follow the instructions here (glfw build instructions), however I chose not to do that. The following command still seems to work in 2020 however it is not explicitly stated by the glfw online instructions.

cmake -G "Unix Makefiles"

• You may need to run sudo apt-get build-dep glfw3 before (?). I ran both this command and sudo apt install xorg-dev as per the instructions.

• Finally run make

• Now in your project directory, do the following. (Go to your project which uses the glfw libs)

• Create a CMakeLists.txt, mine looks like this

CMAKE_MINIMUM_REQUIRED(VERSION 3.7)
PROJECT(project)

SET(CMAKE_CXX_STANDARD 14)
SET(CMAKE_BUILD_TYPE DEBUG)

set(GLFW_BUILD_DOCS OFF CACHE BOOL "" FORCE)
set(GLFW_BUILD_TESTS OFF CACHE BOOL "" FORCE)
set(GLFW_BUILD_EXAMPLES OFF CACHE BOOL "" FORCE)

add_subdirectory(/home/<user>/glfw /home/<user>/glfw/src)


FIND_PACKAGE(OpenGL REQUIRED)

SET(SOURCE_FILES main.cpp)

ADD_EXECUTABLE(project ${SOURCE_FILES})
TARGET_LINK_LIBRARIES(project glfw)
TARGET_LINK_LIBRARIES(project OpenGL::GL)

• If you don't like CMake then I appologize but in my opinion it is the easiest way to get your project working quickly. I would recommend learning to use it, at least to a basic level. Regretably I do not know of any good CMake tutorial

• Then do cmake . and make, your project should be built and linked against glfw3 shared lib

• There is some way of creating a dynamic linked lib. I believe I have used the static method here. Please comment / add a section in this answer below if you know more than I do

• This should work on other systems, if not let me know and I will help if I am able to

To see author and time by commit use git show COMMIT. Which will result in something like this:

commit 13414df70354678b1b9304ebe4b6d204810f867e
Merge: a2a2894 3a1ba8f
Author: You <[email protected]>
Date:   Fri Jul 24 17:46:42 2015 -0700

     Merge remote-tracking branch 'origin/your-feature'

If you want to see which files had been changed, run the following with the values from the Merge line above git diff --stat a2a2894 3a1ba8f.

If you want to see the actual diff, run git --stat a2a2894 3a1ba8f

Perhaps the volume was created via docker-compose? If so, it should get removed by:

docker-compose down --volumes

Despite using display: inline-block. My div would fill the screen width when the children elements had their widths set to % of parent. If anyone else is looking for a solution to this and doesn't mind using screen proportion instead of parent proportion, replace the % with vw for width (Viewport Width), or vh for height (Viewport Height).

Try this, if it helps you

values = ['1', '2', '3']

with open("file.txt", "w") as output:
    output.write(str(values))

add ng-model="$ctrl.formName" attribute to your form, and then in the controller you can access the form as an object inside your controller by this.formName

Good practice nowadays is to use CollectionUtils from either Apache Commons or Spring Framework.

CollectionUtils.isEmpty(list))

This happened to me too, but the problem was actually different: file encoding.

The file was correct, but the file encoding was wrong. It was generated by the export utility of SQL Server and I saved it as Unicode.

The file itself looked good in the text editor, but when I opened the *.bad file that the SQL*loader generated with the rejected lines, I saw it had bad characters between every original character. Then I though about the encoding.

I opened the original file with Notepad++ and converted it to ANSI, and everything loaded properly.

The initiale code must have borderBottomLeftRadius: 0px

Here is the resulting combined source based answer

private void clearAppData() {
    try {
        // clearing app data
        if (Build.VERSION_CODES.KITKAT <= Build.VERSION.SDK_INT) {
            ((ActivityManager)getSystemService(ACTIVITY_SERVICE)).clearApplicationUserData(); // note: it has a return value!
        } else {
            String packageName = getApplicationContext().getPackageName();
            Runtime runtime = Runtime.getRuntime();
            runtime.exec("pm clear "+packageName);
        }

    } catch (Exception e) {
        e.printStackTrace();
    } 
}

you can check the IMEI #, http://developer.android.com/reference/android/telephony/TelephonyManager.html#getDeviceId%28%29

if i recall on the emulator this return 0. however, there's no documentation i can find that guarantees that. although the emulator might not always return 0, it seems pretty safe that a registered phone would not return 0. what would happen on a non-phone android device, or one without a SIM card installed or one that isn't currently registered on the network?

seems like that'd be a bad idea, to depend on that.

it also means you'd need to ask for permission to read the phone state, which is bad if you don't already require it for something else.

if not that, then there's always flipping some bit somewhere before you finally generate your signed app.

Yes that's possible you have to define your own style for radio buttons, at res/values/styles.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="CustomTheme" parent="android:Theme">
   <item name="android:radioButtonStyle">@style/RadioButton</item>
</style>
<style name="RadioButton" parent="@android:style/Widget.CompoundButton.RadioButton">
   <item name="android:button">@drawable/radio</item>
</style>
</resources>

'radio' here should be a stateful drawable, radio.xml:

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:state_window_focused="false"
        android:drawable="@drawable/radio_hover" />
    <item android:state_checked="false" android:state_window_focused="false"
        android:drawable="@drawable/radio_normal" />
    <item android:state_checked="true" android:state_pressed="true"
        android:drawable="@drawable/radio_active" />
    <item android:state_checked="false" android:state_pressed="true"
        android:drawable="@drawable/radio_active" />
    <item android:state_checked="true" android:state_focused="true"
        android:drawable="@drawable/radio_hover" />
    <item android:state_checked="false" android:state_focused="true"
        android:drawable="@drawable/radio_normal_off" />
    <item android:state_checked="false" android:drawable="@drawable/radio_normal" />
    <item android:state_checked="true" android:drawable="@drawable/radio_hover" />
    </selector>

Then just apply the Custom theme either to whole app or to activities of your choice.

For more info about themes and styles look at http://brainflush.wordpress.com/2009/03/15/understanding-android-themes-and-styles/ that is good guide.

Can be faster then Chris Lercher answer when most of in String have exacly 8 char

int length = in.length();
return length == 8 ? in : ("00000000" + in).substring(length);

in my case on my machine 1/8 faster.

You can't do this without JavaScript. Stackoverflow is using the jQuery JavaScript library which attachs functions to HTML elements on page load.

Here's how you could do it with vanilla JavaScript:

<textarea onkeydown="if (event.keyCode == 13) { this.form.submit(); return false; }"></textarea>

Keycode 13 is the enter key.

Here's how you could do it with jQuery like as Stackoverflow does:

<textarea class="commentarea"></textarea>

with

$(document).ready(function() {
    $('.commentarea').keydown(function(event) {
        if (event.which == 13) {
            this.form.submit();
            event.preventDefault();
         }
    });
});

You need to link both a.o and b.o:

gcc -o program a.c b.c

If you have a main() in each file, you cannot link them together.

However, your a.c file contains a reference to doSomething() and expects to be linked with a source file that defines doSomething() and does not define any function that is defined in a.c (such as main()).

You cannot call a function in Process B from Process A. You cannot send a signal to a function; you send signals to processes, using the kill() system call.

The signal() function specifies which function in your current process (program) is going to handle the signal when your process receives the signal.

You have some serious work to do understanding how this is going to work - how ProgramA is going to know which process ID to send the signal to. The code in b.c is going to need to call signal() with dosomething as the signal handler. The code in a.c is simply going to send the signal to the other process.

I succinctified Poyson 1's answer like so:

public static bool IsValidEmailAddress(string candidateEmailAddr)
{
    string regexExpresion = "\\w+([-+.']\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*";
    return (Regex.IsMatch(candidateEmailAddr, regexExpresion)) && 
           (Regex.Replace(candidateEmailAddr, regexExpresion, string.Empty).Length == 0);
}

If your goal is to set a static string in the toolbar, the easiest way to do it is to simply set the activity label in AndroidManifest.xml:

<activity android:name=".xxxxActivity"
          android:label="@string/string_id" />

The toolbar will get this string without any code. (works for me with v27 libraries.)

You can write like below. Check out the syntax guidelines in this thread

AClass[] array;
...
array = new AClass[]{object1, object2};

If you find arrays annoying better use ArrayList.

You could simply use target="_blank" on the form.

<form action="action.php" method="post" target="_blank">
    <input type="hidden" name="something" value="some value">
</form>

Add hidden inputs in the way you prefer, and then simply submit the form with JS.

You may need to run the cron job as a user with permissions to execute the PHP script. Try executing the cron job as root, using the command runuser (man runuser). Or create a system crontable and run the PHP script as an authorized user, as @Philip described.

I provide a detailed answer how to use cron in this stackoverflow post.

How to write a cron that will run a script every day at midnight?

$('form[name="frmSave"]') is correct. You mentioned you thought this would get all children with the name frmsave inside the form; this would only happen if there was a space or other combinator between the form and the selector, eg: $('form [name="frmSave"]');

$('form[name="frmSave"]') literally means find all forms with the name frmSave, because there is no combinator involved.

I would suggest you to have a look into Moment.js if you have trouble with Angular. At least it is a quick workaround without spending too much time.

I noticed few things:

Ctrl+/ toggles Folding-enabled or -disabled.

It is Ctrl+* that expands. Ctrl+Shift+* collapses just like Ctrl+Shift+/

The whole code if somebody need it.

void alarm(Context context, Calendar calendar) {
    AlarmManager alarmManager = (AlarmManager)context.getSystemService(ALARM_SERVICE);

    final String SOME_ACTION = "com.android.mytabs.MytabsActivity.AlarmReceiver";
    IntentFilter intentFilter = new IntentFilter(SOME_ACTION);

    AlarmReceiver mReceiver = new AlarmReceiver();
    context.registerReceiver(mReceiver, intentFilter);

    Intent anotherIntent = new Intent(SOME_ACTION);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, anotherIntent, 0);
    alramManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

    Toast.makeText(context, "Added", Toast.LENGTH_LONG).show();
}

class AlarmReceiver extends BroadcastReceiver {     
    @Override
    public void onReceive(Context context, Intent arg1) {
        Toast.makeText(context, "Started", Toast.LENGTH_LONG).show();
    }
}

strip does nothing but, removes the the whitespace in your string. If you want to remove the extra whitepace from front and back of your string, you can use strip.

The example string which can illustrate that is this:

In [2]: x = "something \t like     \t this"
In [4]: x.split('\t')
Out[4]: ['something ', ' like     ', ' this']

See, even after splitting with \t there is extra whitespace in first and second items which can be removed using strip in your code.

Wildcards can only be used in the ServerAlias rather than the ServerName. Something which had me stumped.

For your use case, the following should suffice

<VirtualHost *:80>
    ServerAlias *.example.com
    VirtualDocumentRoot /var/www/%1/
</VirtualHost>

Change the button to

<button id="search">Search</button>

and add the following script

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('#search').click(function() {
  var keyWord = $('#Keyword').val();
  $('#searchResults').load(url, { searchText: keyWord });
})

and modify the controller method to accept the search text

public ActionResult DisplaySearchResults(string searchText)
{
  var model = // build list based on parameter searchText
   return PartialView("SearchResults", model);
}

The jQuery .load method calls your controller method, passing the value of the search text and updates the contents of the <div> with the partial view.

Side note: The use of a <form> tag and @Html.ValidationSummary() and @Html.ValidationMessageFor() are probably not necessary here. Your never returning the Index view so ValidationSummary makes no sense and I assume you want a null search text to return all results, and in any case you do not have any validation attributes for property Keyword so there is nothing to validate.

Edit

Based on OP's comments that SearchCriterionModel will contain multiple properties with validation attributes, then the approach would be to include a submit button and handle the forms .submit() event

<input type="submit" value="Search" />

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('form').submit(function() {
  if (!$(this).valid()) { 
    return false; // prevent the ajax call if validation errors
  }
  var form = $(this).serialize();
  $('#searchResults').load(url, form);
  return false; // prevent the default submit action
})

and the controller method would be

public ActionResult DisplaySearchResults(SearchCriterionModel criteria)
{
  var model = // build list based on the properties of criteria
  return PartialView("SearchResults", model);
}

in_array() is fine if you're only checking but if you need to check that a value exists and return the associated key, array_search is a better option.

$data = [
    'hello',
    'world'
];

$key = array_search('world', $data);

if ($key) {
    echo 'Key is ' . $key;
} else {
    echo 'Key not found';
}

This will print "Key is 1"

Its simpler than you think.

According to Microsoft: The lock keyword ensures that one thread does not enter a critical section of code while another thread is in the critical section. If another thread tries to enter a locked code, it will wait, block, until the object is released.

The lock keyword calls Enter at the start of the block and Exit at the end of the block. lock keyword actually handles Monitor class at back end.

For example:

private static readonly Object obj = new Object();

lock (obj)
{
    // critical section
}

In the above code, first the thread enters a critical section, and then it will lock obj. When another thread tries to enter, it will also try to lock obj, which is already locked by the first thread. Second thread will have to wait for the first thread to release obj. When the first thread leaves, then another thread will lock obj and will enter the critical section.

Install the ASP.NET AJAX Control Toolkit

1. Download the ZIP file AjaxControlToolkit-Framework3.5SP1-DllOnly.zip from the ASP.NET AJAX Control Toolkit Releases page of the CodePlex web site.

2. Copy the contents of this zip file directly into the bin directory of your web site.

Update web.config

3. Put this in your web.config under the <controls> section:

   <?xml version="1.0"?>
   <configuration>
       ...
       <system.web>
           ...
           <pages>
               ...
               <controls>
                   ...
                   <add tagPrefix="ajaxtoolkit"
                       namespace="AjaxControlToolkit"
                       assembly="AjaxControlToolKit"/>
               </controls>
           </pages>
           ...
       </system.web>
       ...
   </configuration>
   

Setup Visual Studio

4. Right-click on the Toolbox and select "Add Tab", and add a tab called "AJAX Control Toolkit"

5. Inside that tab, right-click on the Toolbox and select "Choose Items..."

6. When the "Choose Toolbox Items" dialog appears, click the "Browse..." button. Navigate to your project's "bin" folder. Inside that folder, select "AjaxControlToolkit.dll" and click OK. Click OK again to close the Choose Items Dialog.

You can now use the controls in your web sites!

function listCookies() {
    let cookies = document.cookie.split(';')
    cookies.map((cookie, n) => console.log(`${n}:`, decodeURIComponent(cookie)))
}

function findCookie(e) {
  let cookies = document.cookie.split(';')
  cookies.map((cookie, n) => cookie.includes(e) && console.log(decodeURIComponent(cookie), n))
}

This is specifically for the window you're in. Tried to keep it clean and concise.

I've been using some simple CSS and it seems to remove them and work fine.

input[type=number]::-webkit-inner-spin-button, _x000D_
input[type=number]::-webkit-outer-spin-button { _x000D_
    -webkit-appearance: none;_x000D_
    -moz-appearance: none;_x000D_
    appearance: none;_x000D_

This error will also occur if you call .ps1 file from a .bat file and file path has spaces.

The fix is to make sure there are no spaces in the path of .ps1 file.

create LOGIN guest WITH PASSWORD='guest@123', CHECK_POLICY = OFF;

Be sure when you want to exceute the following

DENY VIEW ANY DATABASE TO guest;

ALTER AUTHORIZATION ON DATABASE::BiddingSystemDB TO guest

Selected Database should be Master

You did not activate the virtual environment before using pip.

Try it with:

$(your venv path) . bin/activate

And then use pip -r requirements.txt on your main folder

I had same problem and the solution was very simple. Solution : foreign keys declared in table should not set to be not null.

reference : If you specify a SET NULL action, make sure that you have not declared the columns in the child table as NOT NULL. (ref )

Excel automatically does this whenever you have a vertical column of items. If you select the blank cell below (or above) the column and start typing, it does autocomplete based on everything in the column.

Without over-complicating the problem, to grant the EXECUTE on chosen database:

USE [DB]
GRANT EXEC TO [User_Name];

Option 1 : Split email address into multiple parts and create an array in JavaScript out of these parts. Next join these parts in the correct order and use the .innerHTML property to add the email address to the web page.

 <span id="email">  </span>   // blank tag

 <script>
 var parts = ["info", "XXXXabc", "com", "&#46;", "&#64;"];
 var email = parts[0] + parts[4] + parts[1] + parts[3] + parts[2];
 document.getElementById("email").innerHTML=email; 
 </script>

Option 2 : Use image instead of email text

Image creator website from text : http://www.chxo.com/labelgen/

Option 3 : We can use AT instead of "@" and DOT instead of " . "

i.e :

 info(AT)XXXabc(DOT)com

Can I just ask about the long term need for this facility - is it for debuging purposes?

If so, then you may want to consider using a proper debugger, such as the one found in Visual Studio, as this allows you to step through the procedure in a more controlled way, and avoids having to constantly add/remove PRINT statement from the procedure.

Just my opinion, but I prefer the debugger approach - for code and databases.

Was facing the same issue, used this one

Console.log(Date.parse("Jun 13, 2018 10:50:39 GMT+1"));

It will return milliseconds to which u can check have +100 timzone intialize British time Hope it helps!!

C++ has Automatic variables - not Stack variables.

Automatic variable means that C++ compiler handles memory allocation / free by itself. C++ can automatically handle objects of any class - no matter whether it has dynamically allocated members or not. It's achieved by strong guarantee of C++ that object's destructor will be called automatically when execution is going out of scope where automatic variable was declared. Inside of a C++ object can be a lot of dynamic allocations with new in constructor, and when such an object is declared as an automatic variable - all dynamic allocations will be performed, and freed then in destructor.

Stack variables in C can't be dynamically allocated. Stack in C can store pointers, or fixed arrays or structs - all of fixed size, and these things are being allocated in memory in linear order. When a C program frees a stack variable - it just moves stack pointer back and nothing more.

Even though C++ programs can use Stack memory segment for storing primitive types, function's args, or other, - it's all decided by C++ compiler, not by program developer. Thus, it is conceptually wrong to equal C++ automatic variables and C stack variables.

This code is better.

public static  byte[] getByteArrayFromImageView(ImageView imageView)
    {
        BitmapDrawable bitmapDrawable = ((BitmapDrawable) imageView.getDrawable());
        Bitmap bitmap;
        if(bitmapDrawable==null){
            imageView.buildDrawingCache();
            bitmap = imageView.getDrawingCache();
            imageView.buildDrawingCache(false);
        }else
        {
            bitmap = bitmapDrawable .getBitmap();
        }
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
        return stream.toByteArray();
    }

Here's an answer from the book "The C++ Programming Language" by Bjarne Stroustrup. If you don't want to see the video, you can see the text below:

Consider this snippet. Returning from an operator+ involves copying the result out of the local variable res and into someplace where the caller can access it.

Vector operator+(const Vector& a, const Vector& b)
{
    if (a.size()!=b.size())
        throw Vector_siz e_mismatch{};
    Vector res(a.size());
        for (int i=0; i!=a.size(); ++i)
            res[i]=a[i]+b[i];
    return res;
}

We didn’t really want a copy; we just wanted to get the result out of a function. So we need to move a Vector rather than to copy it. We can define move constructor as follows:

class Vector {
    // ...
    Vector(const Vector& a); // copy constructor
    Vector& operator=(const Vector& a); // copy assignment
    Vector(Vector&& a); // move constructor
    Vector& operator=(Vector&& a); // move assignment
};

Vector::Vector(Vector&& a)
    :elem{a.elem}, // "grab the elements" from a
    sz{a.sz}
{
    a.elem = nullptr; // now a has no elements
    a.sz = 0;
}

The && means "rvalue reference" and is a reference to which we can bind an rvalue. "rvalue"’ is intended to complement "lvalue" which roughly means "something that can appear on the left-hand side of an assignment." So an rvalue means roughly "a value that you can’t assign to", such as an integer returned by a function call, and the res local variable in operator+() for Vectors.

Now, the statement return res; will not copy!

To remove spaces from left/right, use LTRIM/RTRIM. What you had

UPDATE *tablename*
   SET *columnname* = LTRIM(RTRIM(*columnname*));

would have worked on ALL the rows. To minimize updates if you don't need to update, the update code is unchanged, but the LIKE expression in the WHERE clause would have been

UPDATE [tablename]
   SET [columnname] = LTRIM(RTRIM([columnname]))
 WHERE 32 in (ASCII([columname]), ASCII(REVERSE([columname])));

Note: 32 is the ascii code for the space character.

visibility:hidden will hide the element but element is their with DOM. And in case of display:none it'll remove the element from the DOM.

So you have option for element to either hide or unhide. But once you delete it ( I mean display none) it has not clear opposite value. display have several values like display:block,display:inline, display:inline-block and many other. you can check it out from W3C.

Current css version still doesn't support selector find by content. But there is a way, by using css selector find by attribute, but you have to put some identifier on all of the <td> that have $ inside. Example: using nth-child in tables tr td

html

<tr>
    <td>&nbsp;</td>
    <td data-rel='$'>$</td>
    <td>&nbsp;</td>
</tr>

css

table tr td[data-rel='$'] {
    background-color: #333;
    color: white;
}

Please try these example.

table tr td[data-content='$'] {_x000D_
    background-color: #333;_x000D_
    color: white;_x000D_
}

<table border="1">_x000D_
    <tr>_x000D_
        <td>A</td>_x000D_
        <td data-content='$'>$</td>_x000D_
        <td>B</td>_x000D_
        <td data-content='$'>$</td>_x000D_
        <td>C</td>_x000D_
        <td data-content='$'>$</td>_x000D_
        <td>D</td>_x000D_
    </tr>_x000D_
</table>

As others have pointed out you are looking for std::numeric_limits<double>::quiet_NaN() although I have to say I prefer the cppreference.com documents. Especially because this statement is a little vague:

Only meaningful if std::numeric_limits::has_quiet_NaN == true.

and it was simple to figure out what this means on this site, if you check their section on std::numeric_limits::has_quiet_NaN it says:

This constant is meaningful for all floating-point types and is guaranteed to be true if std::numeric_limits::is_iec559 == true.

which as explained here if true means your platform supports IEEE 754 standard. This previous thread explains this should be true for most situations.

From Mac OS Catalina .bash_profile is replaced with .zprofile

Step 1: Create a .zprofile

touch .zprofile

Step 2:

nano .zprofile

type below line in this

source ~/.bash_profile

and save(ctrl+o return ctrl+x)

Step 3: Restart your terminal

To Add Git Branch Name Now you can add below lines in .bash_profile

    parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}

export PS1="\u@\h \[\033[32m\]\w - \$(parse_git_branch)\[\033[00m\] $ "

Restart your terminal this will work.

Note: Even you can rename .bash_profile to .zprofile that also works.

In Swift 4.1 and Xcode 9.4.1

I have two apps 1)PageViewControllerExample and 2)DelegateExample. Now i want to open DelegateExample app with PageViewControllerExample app. When i click open button in PageViewControllerExample, DelegateExample app will be opened.

For this we need to make some changes in .plist files for both the apps.

Step 1

In DelegateExample app open .plist file and add URL Types and URL Schemes. Here we need to add our required name like "myapp".

Step 2

In PageViewControllerExample app open .plist file and add this code

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>myapp</string>
</array>

Now we can open DelegateExample app when we click button in PageViewControllerExample.

//In PageViewControllerExample create IBAction
@IBAction func openapp(_ sender: UIButton) {

    let customURL = URL(string: "myapp://")
    if UIApplication.shared.canOpenURL(customURL!) {

        //let systemVersion = UIDevice.current.systemVersion//Get OS version
        //if Double(systemVersion)! >= 10.0 {//10 or above versions
            //print(systemVersion)
            //UIApplication.shared.open(customURL!, options: [:], completionHandler: nil)
        //} else {
            //UIApplication.shared.openURL(customURL!)
        //}

        //OR

        if #available(iOS 10.0, *) {
            UIApplication.shared.open(customURL!, options: [:], completionHandler: nil)
        } else {
            UIApplication.shared.openURL(customURL!)
        }
    } else {
         //Print alert here
    }
}

You can use append or prepend

The .append() method inserts the specified content as the last child of each element in the jQuery collection (To insert it as the first child, use .prepend()).

$("#tagscloud span").append(second);
$("#tagscloud span").append(third);
$("#tagscloud span").prepend(first);

Maybe this is a bit redundant, but no one appeared to have mentioned this as a solution.

As a beginner in SQL I find that when using a BEGIN and END SSMS usually adds a squiggly line with incorrect syntax near 'END' to END, simply because there's no content in between yet. If you're just setting up BEGIN and END to get started and add the actual query later, then simply add a bogus PRINT statement so SSMS stops bothering you.

For example:

IF (1=1)
BEGIN
  PRINT 'BOGUS'
END

The following will indeed set you on the wrong track, thinking you made a syntax error which in this case just means you still need to add content in between BEGIN and END:

IF (1=1)
BEGIN
END

If your file looks like this:

[
    {
        "firstname": "toto",
        "lastname": "titi"
    },
    {
        "firstname": "toto2",
        "lastname": "titi2"
    },
]

You can do:

import json from './json/data.json';
// ....
json.forEach(x => { console.log(x.firstname, x.lastname); });

All I can think of is that something is over-riding this afterwards.

You are including the reset styles first, right?

git pull --rebase may hide a history rewriting from a collaborator git push --force. I recommend to use git pull --rebase only if you know you forgot to push your commits before someone else does the same.

If you did not commit anything, but your working space is not clean, just git stash before to git pull. This way you won't silently rewrite your history (which could silently drop some of your work).

Best way would be to declare Boolean variable within the code block and return it at end of code, like this:

public boolean Test(){
    boolean booleanFlag= true; 
    if (A>B)
    {booleanFlag= true;}
    else 
    {booleanFlag = false;}
    return booleanFlag;

}

I find this the best way.

Try this:

for(String str: myList) {
    if(str.trim().equals("A"))
       return true;
}
return false;

You need to use str.equals or str.equalsIgnoreCase instead of contains because contains in string works not the same as contains in List

List<String> s = Arrays.asList("BAB", "SAB", "DAS");
s.contains("A"); // false
"BAB".contains("A"); // true

Store data in SharedPreference

SharedPreferences mprefs = getSharedPreferences(AppConstant.PREFS_NAME, MODE_PRIVATE)
mprefs.edit().putString(AppConstant.USER_ID, resUserID).apply();

Actually, in C++14 it can be done with a very few lines of code.

This is a very similar in idea to @Paul's solution. Due to things missing from C++11, that solution is a bit unnecessarily bloated (plus defining in std smells). Thanks to C++14 we can make it a lot more readable.

The key observation is that range-based for-loops work by relying on begin() and end() in order to acquire the range's iterators. Thanks to ADL, one doesn't even need to define their custom begin() and end() in the std:: namespace.

Here is a very simple-sample solution:

// -------------------------------------------------------------------
// --- Reversed iterable

template <typename T>
struct reversion_wrapper { T& iterable; };

template <typename T>
auto begin (reversion_wrapper<T> w) { return std::rbegin(w.iterable); }

template <typename T>
auto end (reversion_wrapper<T> w) { return std::rend(w.iterable); }

template <typename T>
reversion_wrapper<T> reverse (T&& iterable) { return { iterable }; }

This works like a charm, for instance:

template <typename T>
void print_iterable (std::ostream& out, const T& iterable)
{
    for (auto&& element: iterable)
        out << element << ',';
    out << '\n';
}

int main (int, char**)
{
    using namespace std;

    // on prvalues
    print_iterable(cout, reverse(initializer_list<int> { 1, 2, 3, 4, }));

    // on const lvalue references
    const list<int> ints_list { 1, 2, 3, 4, };
    for (auto&& el: reverse(ints_list))
        cout << el << ',';
    cout << '\n';

    // on mutable lvalue references
    vector<int> ints_vec { 0, 0, 0, 0, };
    size_t i = 0;
    for (int& el: reverse(ints_vec))
        el += i++;
    print_iterable(cout, ints_vec);
    print_iterable(cout, reverse(ints_vec));

    return 0;
}

prints as expected

4,3,2,1,
4,3,2,1,
3,2,1,0,
0,1,2,3,

NOTE std::rbegin(), std::rend(), and std::make_reverse_iterator() are not yet implemented in GCC-4.9. I write these examples according to the standard, but they would not compile in stable g++. Nevertheless, adding temporary stubs for these three functions is very easy. Here is a sample implementation, definitely not complete but works well enough for most cases:

// --------------------------------------------------
template <typename I>
reverse_iterator<I> make_reverse_iterator (I i)
{
    return std::reverse_iterator<I> { i };
}

// --------------------------------------------------
template <typename T>
auto rbegin (T& iterable)
{
    return make_reverse_iterator(iterable.end());
}

template <typename T>
auto rend (T& iterable)
{
    return make_reverse_iterator(iterable.begin());
}

// const container variants

template <typename T>
auto rbegin (const T& iterable)
{
    return make_reverse_iterator(iterable.end());
}

template <typename T>
auto rend (const T& iterable)
{
    return make_reverse_iterator(iterable.begin());
}

Here is a easy method.

First parse the JSON from url -

public String readJSONFeed(String URL) {
    StringBuilder stringBuilder = new StringBuilder();
    HttpClient httpClient = new DefaultHttpClient();
    HttpGet httpGet = new HttpGet(URL);

    try {

        HttpResponse response = httpClient.execute(httpGet);
        StatusLine statusLine = response.getStatusLine();
        int statusCode = statusLine.getStatusCode();

        if (statusCode == 200) {

            HttpEntity entity = response.getEntity();
            InputStream inputStream = entity.getContent();
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(inputStream));
            String line;
            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line);
            }

            inputStream.close();

        } else {
            Log.d("JSON", "Failed to download file");
        }
    } catch (Exception e) {
        Log.d("readJSONFeed", e.getLocalizedMessage());
    }
    return stringBuilder.toString();
}

Then place a task and then read the desired value from JSON -

private class ReadPlacesFeedTask extends AsyncTask<String, Void, String> {
    protected String doInBackground(String... urls) {

        return readJSONFeed(urls[0]);
    }

    protected void onPostExecute(String result) {

        JSONObject json;
        try {
            json = new JSONObject(result);

        ////CREATE A JSON OBJECT////

        JSONObject data = json.getJSONObject("JSON OBJECT NAME");

        ////GET A STRING////

        String title = data.getString("");

        //Similarly you can get other types of data
        //Replace String to the desired data type like int or boolean etc.

        } catch (JSONException e1) {
            e1.printStackTrace();

        }

        //GETTINGS DATA FROM JSON ARRAY//

        try {

            JSONObject jsonObject = new JSONObject(result);
            JSONArray postalCodesItems = new JSONArray(
                    jsonObject.getString("postalCodes"));

                JSONObject postalCodesItem = postalCodesItems
                        .getJSONObject(1);

        } catch (Exception e) {
            Log.d("ReadPlacesFeedTask", e.getLocalizedMessage());
        }
    }
}

You can then place a task like this -

new ReadPlacesFeedTask()
    .execute("JSON URL");

Yes, there is a shortcut for commenting out lines in Python 3.6 (Spyder).

For Single Line Comment, you can use Ctrl+1. It will look like this #This is a sample piece of code

For multi-line comments, you can use Ctrl+4. It will look like this

#============= \#your piece of code \#some more code \#=============

Note : \ represents that the code is carried to another line.

Messing around with the same answers:

$ git config --global alias.find '!git log --color -p -S '

• ! is needed because other way, git do not pass argument correctly to -S. See this response
• --color and -p helps to show exactly "whatchanged"

Now you can do

$ git find <whatever>

or

$ git find <whatever> --all
$ git find <whatever> master develop

Another great implementation is balupton's jQuery History which will use the native onhashchange event if it is supported by the browser, if not it will use an iframe or interval appropriately for the browser to ensure all the expected functionality is successfully emulated. It also provides a nice interface to bind to certain states.

Another project worth noting as well is jQuery Ajaxy which is pretty much an extension for jQuery History to add ajax to the mix. As when you start using ajax with hashes it get's quite complicated!

Try this.

// uses the URL class
function setParam(key, value) {
            let url = new URL(window.document.location);
            let params = new URLSearchParams(url.search.slice(1));

            if (params.has(key)) {
                params.set(key, value);
            }else {
                params.append(key, value);
            }
        }

Well, In my applications I just need to Add a reference to "DocumentFormat.OpenXml" under .Net tab and both references (DocumentFormat.OpenXml and WindowsBase) are always added automatically. But They are not included within the Bin folder. So when the Application is published to an external server I always place DocumentFormat.OpenXml.dll under the Bin folder manually. Or set the reference "Copy Local" property to true.

We have just uploaded AmbilWarna color picker to Maven:

https://github.com/yukuku/ambilwarna

It can be used either as a dialog or as a Preference entry.

The libraries go to some lengths to get accurate offsets for an element.
here's a simple function that does the job in every circumstances that I've tried.

function getOffset( el ) {
    var _x = 0;
    var _y = 0;
    while( el && !isNaN( el.offsetLeft ) && !isNaN( el.offsetTop ) ) {
        _x += el.offsetLeft - el.scrollLeft;
        _y += el.offsetTop - el.scrollTop;
        el = el.offsetParent;
    }
    return { top: _y, left: _x };
}
var x = getOffset( document.getElementById('yourElId') ).left; 

Simple example based off of @Tuan Zaidi's example above which seemed the easiest. Didn't know you can do the filter on the outside of OPENQUERY... so much easier!

However in my case I needed to stuff it in a variable so I created an additional Sub Query Level to return a single value.

The following regex extract anything between the parenthesis:

PS> $prog = [regex]::match($s,'\(([^\)]+)\)').Groups[1].Value
PS> $prog
SUB RAD MSD 50R III


Explanation (created with RegexBuddy)

Match the character '(' literally «\(»
Match the regular expression below and capture its match into backreference number 1 «([^\)]+)»
   Match any character that is NOT a ) character «[^\)]+»
      Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
Match the character ')' literally «\)»

In short, yes. But there are times when you might favor one vs. the other. Google "case switch vs. if else". There are some discussions already on SO too. Also, here is a good video that talks about it in the context of MATLAB:

http://blogs.mathworks.com/pick/2008/01/02/matlab-basics-switch-case-vs-if-elseif/

Personally, when I have 3 or more cases, I usually just go with case/switch.

it is because you already defined the 'abuse_id' as auto increment, then there is no need to insert its value. it will be inserted automatically. the error comes because you are inserting 1 many times that is duplication of data. the primary key should be unique. should not be repeated.

the thing you have to do is to change your insertion query as below

INSERT INTO  `abuses` (  `user_id` ,  `abuser_username` ,  `comment` ,  `reg_date` , `auction_id` ) 
VALUES ( 100020,  'artictundra', 'I placed a bid for it more than an hour ago. It is still active. I     thought I was supposed to get an email after 15 minutes.', 1338052850, 108625 ) ;

Similar to Oli's answer, I use an argument Object and an Object which defines the default values. With a little bit of sugar...

/**
 * Updates an object's properties with other objects' properties. All
 * additional non-falsy arguments will have their properties copied to the
 * destination object, in the order given.
 */
function extend(dest) {
  for (var i = 1, l = arguments.length; i < l; i++) {
    var src = arguments[i]
    if (!src) {
      continue
    }
    for (var property in src) {
      if (src.hasOwnProperty(property)) {
        dest[property] = src[property]
      }
    }
  }
  return dest
}

/**
 * Inherit another function's prototype without invoking the function.
 */
function inherits(child, parent) {
  var F = function() {}
  F.prototype = parent.prototype
  child.prototype = new F()
  child.prototype.constructor = child
  return child
}

...this can be made a bit nicer.

function Field(kwargs) {
  kwargs = extend({
    required: true, widget: null, label: null, initial: null,
    helpText: null, errorMessages: null
  }, kwargs)
  this.required = kwargs.required
  this.label = kwargs.label
  this.initial = kwargs.initial
  // ...and so on...
}

function CharField(kwargs) {
  kwargs = extend({
    maxLength: null, minLength: null
  }, kwargs)
  this.maxLength = kwargs.maxLength
  this.minLength = kwargs.minLength
  Field.call(this, kwargs)
}
inherits(CharField, Field)

What's nice about this method?

• You can omit as many arguments as you like - if you only want to override the value of one argument, you can just provide that argument, instead of having to explicitly pass undefined when, say there are 5 arguments and you only want to customise the last one, as you would have to do with some of the other methods suggested.
• When working with a constructor Function for an object which inherits from another, it's easy to accept any arguments which are required by the constructor of the Object you're inheriting from, as you don't have to name those arguments in your constructor signature, or even provide your own defaults (let the parent Object's constructor do that for you, as seen above when CharField calls Field's constructor).
• Child objects in inheritance hierarchies can customise arguments for their parent constructor as they see fit, enforcing their own default values or ensuring that a certain value will always be used.

matrix multiplication, see the following example:

> A <- matrix (c(1,3,4, 5,8,9, 1,3,3), 3,3)
> A
     [,1] [,2] [,3]
[1,]    1    5    1
[2,]    3    8    3
[3,]    4    9    3
> 
> B <- matrix (c(2,4,5, 8,9,2, 3,4,5), 3,3)
> 
> B
     [,1] [,2] [,3]
[1,]    2    8    3
[2,]    4    9    4
[3,]    5    2    5
> 
> 
> A %*% B
     [,1] [,2] [,3]
[1,]   27   55   28
[2,]   53  102   56
[3,]   59  119   63

> B %*% A
     [,1] [,2] [,3]
[1,]   38  101   35
[2,]   47  128   43
[3,]   31   86   26

Also see:

http://en.wikipedia.org/wiki/Matrix_multiplication

If this does not follow the size of matrix rule you will get the error:

> A <- matrix(c(1,2,3,4,5,6), 3,2)
    > A
     [,1] [,2]
[1,]    1    4
[2,]    2    5
[3,]    3    6

> B <- matrix (c(3,1,3,4,4,4,4,4,3), 3,3)

> B
         [,1] [,2] [,3]
    [1,]    3    4    4
    [2,]    1    4    4
    [3,]    3    4    3
    > A%*%B
    Error in A %*% B : non-conformable arguments

I would like to refer a previous question, Because I have faced same problem and solved by this solution. First of all a constraint is always built with a Hash value in it's name. So problem is this HASH is varies in different Machine or Database. For example DF__Companies__IsGlo__6AB17FE4 here 6AB17FE4 is the hash value(8 bit). So I am referring a single script which will be fruitful to all

DECLARE @Command NVARCHAR(MAX)
     declare @table_name nvarchar(256)
     declare @col_name nvarchar(256)
     set @table_name = N'ProcedureAlerts'
     set @col_name = N'EmailSent'

     select @Command ='Alter Table dbo.ProcedureAlerts Drop Constraint [' + ( select d.name
     from 
         sys.tables t
         join sys.default_constraints d on d.parent_object_id = t.object_id
         join sys.columns c on c.object_id = t.object_id
                               and c.column_id = d.parent_column_id
     where 
         t.name = @table_name
         and c.name = @col_name) + ']'

    --print @Command
    exec sp_executesql @Command

It will drop your default constraint. However if you want to create it again you can simply try this

ALTER TABLE [dbo].[ProcedureAlerts] ADD DEFAULT((0)) FOR [EmailSent]

Finally, just simply run a DROP command to drop the column.

I got exactly the same error in Windows 8 while trying to export decision tree digraph using tree.export_graphviz! Then I installed GraphViz from this link. And then I followed the below steps which resolved my issue:

• Right click on My PC >> click on "Change Settings" under "Computer name, domain, and workgroup settings"
• It will open the System Properties window; Goto 'Advanced' tab >> click on 'Environment Variables' >> Under "System Variables" >> select 'Path' and click on 'Edit' >> In 'Variable Value' field, put a semicolon (;) at the end of existing value and then include the path of its installation folder (e.g. ;C:\Program Files (x86)\Graphviz2.38\bin) >> Click on 'Ok' >> 'Ok' >> 'Ok'
• Restart your PC as environment variables are changed

You can use the apply method to apply an arbitrary function to the grouped data. So if you want a set, apply set. If you want a list, apply list.

>>> d
   A       B
0  1    This
1  2      is
2  3       a
3  4  random
4  1  string
5  2       !
>>> d.groupby('A')['B'].apply(list)
A
1    [This, string]
2           [is, !]
3               [a]
4          [random]
dtype: object

If you want something else, just write a function that does what you want and then apply that.

Configuring this worked for me: -vmargs -Xms1536m -Xmx2048m -XX:MaxPermSize=1024m on Eclipse Java Photon June 2018

Running Windows 10, 8 GB ram and 64 bit. You can extend -Xmx2048 -XX:MaxpermSize= 1024m to 4096m too, if your computer has good ram.Mine worked well.

DO you use "group by" in the SSRS table?

I had a report with 3 grouped by fields and I noticed that the report runed very slowly despite having a light query, to the point where I can't even dial values in the search field.

Than I removed the groupings and now the report goes up in seconds and everything works in an instant.

Note: Apply the class info_link to any link you want to get the info from.

<a class="info_link" href="~/Resumes/Resumes1271354404687.docx">
    ~/Resumes/Resumes1271354404687.docx
</a>

For href:

$(function(){
  $('.info_link').click(function(){
    alert($(this).attr('href'));
    // or alert($(this).hash();
  });
});

For Text:

$(function(){
  $('.info_link').click(function(){
    alert($(this).text());
  });
});

.

Update Based On Question Edit

You can get them like this now:

For href:

$(function(){
  $('div.res a').click(function(){
    alert($(this).attr('href'));
    // or alert($(this).hash();
  });
});

For Text:

$(function(){
  $('div.res a').click(function(){
    alert($(this).text());
  });
});

You can do the following :-

$(document).ready(function(){
    $("#id").trigger("click");
});

The comment in your code is wrong. INADDR_ANY doesn't put server's IP automatically'. It essentially puts 0.0.0.0, for the reasons explained in mark4o's answer.

I stumbled across this article looking for a similar answer. I read @vsync example Using javascript's Number.prototype.toLocaleString: and it appeared to work well. The only complaint I had was that if you had more than a single input type="currency" within your page it would only modify the first instance of it.

As he mentions in his comments it was only designed as an example for stackoverflow.

However, the example worked well for me and although I have little experience with JS I figured out how to modify it so that it will work with multiple input type="currency" on the page using the document.querySelectorAll rather than document.querySelector and adding a for loop.

I hope this can be useful for someone else. ( Credit for the bulk of the code is @vsync )

var currencyInput = document.querySelectorAll( 'input[type="currency"]' );

for ( var i = 0; i < currencyInput.length; i++ ) {

    var currency = 'GBP'
    onBlur( {
        target: currencyInput[ i ]
    } )

    currencyInput[ i ].addEventListener( 'focus', onFocus )
    currencyInput[ i ].addEventListener( 'blur', onBlur )

    function localStringToNumber( s ) {
        return Number( String( s ).replace( /[^0-9.-]+/g, "" ) )
    }

    function onFocus( e ) {
        var value = e.target.value;
        e.target.value = value ? localStringToNumber( value ) : ''
    }

    function onBlur( e ) {
        var value = e.target.value

        var options = {
            maximumFractionDigits: 2,
            currency: currency,
            style: "currency",
            currencyDisplay: "symbol"
        }

        e.target.value = ( value || value === 0 ) ?
            localStringToNumber( value ).toLocaleString( undefined, options ) :
            ''
    }
}

    var currencyInput = document.querySelectorAll( 'input[type="currency"]' );

    for ( var i = 0; i < currencyInput.length; i++ ) {

        var currency = 'GBP'
        onBlur( {
            target: currencyInput[ i ]
        } )

        currencyInput[ i ].addEventListener( 'focus', onFocus )
        currencyInput[ i ].addEventListener( 'blur', onBlur )

        function localStringToNumber( s ) {
            return Number( String( s ).replace( /[^0-9.-]+/g, "" ) )
        }

        function onFocus( e ) {
            var value = e.target.value;
            e.target.value = value ? localStringToNumber( value ) : ''
        }

        function onBlur( e ) {
            var value = e.target.value

            var options = {
                maximumFractionDigits: 2,
                currency: currency,
                style: "currency",
                currencyDisplay: "symbol"
            }

            e.target.value = ( value || value === 0 ) ?
                localStringToNumber( value ).toLocaleString( undefined, options ) :
                ''
        }
    }

A more simple solution is as follows. Just check True/False with pandas .duplicated() method and then take sum. Please also see pandas.Series.duplicated — pandas 0.24.1 documentation

import pandas as pd

def has_duplicated(l):
    return pd.Series(l).duplicated().sum() > 0

print(has_duplicated(['one', 'two', 'one']))
# True
print(has_duplicated(['one', 'two', 'three']))
# False

Can you try this,

var ajaxSubmit = function(formE1) {

            var password = $.trim($('#employee_password').val());

             $.ajax({
                type: "POST",
                async: "false",
                url: "checkpass.php",
                data: "password="+password,
                success: function(html) {
                    var arr=$.parseJSON(html);
                    if(arr == "Successful")
                    { 
                         **$("form[name='form']").submit();**
                        return true;
                    }
                    else
                    {    return false;
                    }
                }
            });
              **return false;**
        }

If you define your array like this:

string[][] table = new string[][] {
                       new string[] { "aa", "aaa" },
                       new string[]{ "bb", "bbb" }
};

Then you can use a foreach loop on it.

There is no need to set the environment for running the code on javascript,python,etc in visual studio code what you have to do is just install the Code Runner Extension and then just select the part of the code you want to run and hit the run button present on the upper right corner.

The fileinput module has an inplace mode for writing changes to the file you are processing without using temporary files etc. The module nicely encapsulates the common operation of looping over the lines in a list of files, via an object which transparently keeps track of the file name, line number etc if you should want to inspect them inside the loop.

from fileinput import FileInput
for line in FileInput("file", inplace=1):
    line = line.replace("foobar", "bar")
    print(line)

The same document says

Unlike simple requests (discussed above), "preflighted" requests first send an HTTP OPTIONS request header to the resource on the other domain, in order to determine whether the actual request is safe to send. Cross-site requests are preflighted like this since they may have implications to user data. In particular, a request is preflighted if:

It uses methods other than GET or POST. Also, if POST is used to send request data with a Content-Type other than application/x-www-form-urlencoded, multipart/form-data, or text/plain, e.g. if the POST request sends an XML payload to the server using application/xml or text/xml, then the request is preflighted.

It sets custom headers in the request (e.g. the request uses a header such as X-PINGOTHER)

When the original request is Get with no custom headers, the browser should not make Options request which it does now. The problem is it generates a header X-Requested-With which forces the Options request. See https://github.com/angular/angular.js/pull/1454 on how to remove this header

There is another solution.

Implement IFormatProvider to return a ICustomFormatter that will be passed to string.Format :

public class StringPadder : ICustomFormatter
{
  public string Format(string format, object arg,
       IFormatProvider formatProvider)
  {
     // do padding for string arguments
     // use default for others
  }
}

public class StringPadderFormatProvider : IFormatProvider
{
  public object GetFormat(Type formatType)
  { 
     if (formatType == typeof(ICustomFormatter))
        return new StringPadder();

     return null;
  }
  public static readonly IFormatProvider Default =
     new StringPadderFormatProvider();
}

Then you can use it like this :

string.Format(StringPadderFormatProvider.Default, "->{0:x20}<-", "Hello");

The original answer the author gave works pretty well. Just to extend this idea, you can do something like

group by datediff(minute, 0, [Date])/10

which will allow you to group by a longer period then 60 minutes, say 720, which is half a day etc.

Probably because you're using unsafe code.

Are you doing something with pointers or unmanaged assemblies somewhere?

Via the simulators for respective devices, we can have screenshots with cmd+S command conveniently. And that gives us the exact resolution for the device we simulate. The review team would have mentioned this, but never did. :)

Ordinarily, floats aren't counted in the layout of their parents.

To prevent that, add overflow: hidden to the parent.

One of the powerful features of SQLite is allowing you to choose the storage type. Advantages/disadvantages of each of the three different possibilites:

• ISO8601 string

  • String comparison gives valid results
  • Stores fraction seconds, up to three decimal digits
  • Needs more storage space
  • You will directly see its value when using a database browser
  • Need for parsing for other uses
  • "default current_timestamp" column modifier will store using this format

• Real number

  • High precision regarding fraction seconds
  • Longest time range

• Integer number

  • Lowest storage space
  • Quick operations
  • Small time range
  • Possible year 2038 problem

If you need to compare different types or export to an external application, you're free to use SQLite's own datetime conversion functions as needed.

A lambda is just an anonymous function - a function defined with no name. In some languages, such as Scheme, they are equivalent to named functions. In fact, the function definition is re-written as binding a lambda to a variable internally. In other languages, like Python, there are some (rather needless) distinctions between them, but they behave the same way otherwise.

A closure is any function which closes over the environment in which it was defined. This means that it can access variables not in its parameter list. Examples:

def func(): return h
def anotherfunc(h):
   return func()

This will cause an error, because func does not close over the environment in anotherfunc - h is undefined. func only closes over the global environment. This will work:

def anotherfunc(h):
    def func(): return h
    return func()

Because here, func is defined in anotherfunc, and in python 2.3 and greater (or some number like this) when they almost got closures correct (mutation still doesn't work), this means that it closes over anotherfunc's environment and can access variables inside of it. In Python 3.1+, mutation works too when using the nonlocal keyword.

Another important point - func will continue to close over anotherfunc's environment even when it's no longer being evaluated in anotherfunc. This code will also work:

def anotherfunc(h):
    def func(): return h
    return func

print anotherfunc(10)()

This will print 10.

This, as you notice, has nothing to do with lambdas - they are two different (although related) concepts.

You can have it this way:

It is important to mind the commas after each struct item or set of items.

earnings := []LineItemsType{

        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
    }

Just wanted to provide a different option for this. In my case, I usually work on my individual branches then merge to master, and the individual commits I do to my local are not that important.

Due to a git hook that checks for the appropriate ticket number on Jira but was case sensitive, I was prevented from pushing my code. Also, the commit was done long ago and I didn't want to count how many commits to go back on the rebase.

So what I did was to create a new branch from latest master and squash all commits from problem branch into a single commit on new branch. It was easier for me and I think it's good idea to have it here as future reference.

From latest master:

git checkout -b new-branch

Then

git merge --squash problem-branch
git commit -m "new message"

Nowadays, Alpine images will boot directly into /bin/sh by default, without having to specify a shell to execute:

$ sudo docker run -it --rm alpine  
/ # echo $0  
/bin/sh  

This is since the alpine image Dockerfiles now contain a CMD command, that specifies the shell to execute when the container starts: CMD ["/bin/sh"].

In older Alpine image versions (pre-2017), the CMD command was not used, since Docker used to create an additional layer for CMD which caused the image size to increase. This is something that the Alpine image developers wanted to avoid. In recent Docker versions (1.10+), CMD no longer occupies a layer, and so it was added to alpine images. Therefore, as long as CMD is not overridden, recent Alpine images will boot into /bin/sh.

For reference, see the following commit to the official Alpine Dockerfiles by Glider Labs:
https://github.com/gliderlabs/docker-alpine/commit/ddc19dd95ceb3584ced58be0b8d7e9169d04c7a3#diff-db3dfdee92c17cf53a96578d4900cb5b

The following code should only be used for version socket.io < 0.9
See: http://socket.io/docs/migrating-from-0-9/

It can be done through the handshake/authorization mechanism.

var cookie = require('cookie');
io.set('authorization', function (data, accept) {
    // check if there's a cookie header
    if (data.headers.cookie) {
        // if there is, parse the cookie
        data.cookie = cookie.parse(data.headers.cookie);
        // note that you will need to use the same key to grad the
        // session id, as you specified in the Express setup.
        data.sessionID = data.cookie['express.sid'];
    } else {
       // if there isn't, turn down the connection with a message
       // and leave the function.
       return accept('No cookie transmitted.', false);
    }
    // accept the incoming connection
    accept(null, true);
});

All the attributes, that are assigned to the data object are now accessible through the handshake attribute of the socket.io connection object.

io.sockets.on('connection', function (socket) {
    console.log('sessionID ' + socket.handshake.sessionID);
});

It's also important to note that while getting a list of directory names in a loop, the DirectoryInfo class gets initialized once thus allowing only first-time call. In order to bypass this limitation, ensure you use variables within your loop to store any individual directory's name.

For example, this sample code loops through a list of directories within any parent directory while adding each found directory-name inside a List of string type:

[C#]

string[] parentDirectory = Directory.GetDirectories("/yourpath");
List<string> directories = new List<string>();

foreach (var directory in parentDirectory)
{
    // Notice I've created a DirectoryInfo variable.
    DirectoryInfo dirInfo = new DirectoryInfo(directory);

    // And likewise a name variable for storing the name.
    // If this is not added, only the first directory will
    // be captured in the loop; the rest won't.
    string name = dirInfo.Name;

    // Finally we add the directory name to our defined List.
    directories.Add(name);
}

[VB.NET]

Dim parentDirectory() As String = Directory.GetDirectories("/yourpath")
Dim directories As New List(Of String)()

For Each directory In parentDirectory

    ' Notice I've created a DirectoryInfo variable.
    Dim dirInfo As New DirectoryInfo(directory)

    ' And likewise a name variable for storing the name.
    ' If this is not added, only the first directory will
    ' be captured in the loop; the rest won't.
    Dim name As String = dirInfo.Name

    ' Finally we add the directory name to our defined List.
    directories.Add(name)

Next directory

SparkSession has a number of createDataFrame methods that create a DataFrame given an RDD. I imagine one of these will work for your context.

For example:

def createDataFrame(rowRDD: RDD[Row], schema: StructType): DataFrame

Creates a DataFrame from an RDD containing Rows using the given schema.

Not a Javascript library but it may be a suitable alternative - check out Google Charts where you can generate charts by passing querystring data to their web service.

Do you have any open SQL Server Management Studio windows that are connected to this DB?

Put it in single user mode, and then try again.

You can use the field truncation option to avoid quite so many %x08 characters. For example:

git log --pretty='format:%h %s%n\t%<(12,trunc)%ci%x08%x08, %an <%ae>'

is equivalent to:

git log --pretty='format:%h %s%n\t%ci%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08, %an <%ae>'

And quite a bit easier on the eyes.

Better still, for this particular example, using %cd will honor the --date=<format>, so if you want YYYY-MM-DD, you can do this and avoid %< and %x08 entirely:

git log --date=short --pretty='format:%h %s%n\t%cd, %an <%ae>'

I just noticed this was a bit circular with respect to the original post but I'll leave it in case others arrived here with the same search parameters I did.

Marquis Wang's may well be the best answer when using jQuery.

Here is something quite similar in pure JavaScript, using JavaScript's forEach method. forEach takes a function as an argument. That function will then be called for each item in the array, with said item as the argument.

Short and easy:

var results = [ {"id":"10", "class": "child-of-9"}, {"id":"11", "classd": "child-of-10"} ];

results.forEach(function(item) {
    console.log(item);
});

I assumed openjdk8 would work with tomcat8 but I had to remove it and keep openjdk7 only, this fixed the issue in my case. I really don't know why or if there is something else I could have done.

Validate the INPUT.

$time = strtotime($_POST['dateFrom']);
if ($time) {
  $new_date = date('Y-m-d', $time);
  echo $new_date;
} else {
   echo 'Invalid Date: ' . $_POST['dateFrom'];
  // fix it.
}

Note, until now posted solutions only work for png and jpg!

If you want it even easier without importing further libraries or you want to display an animated or not animated GIF File in your Ipython Notebook. Transform the line where you want to display it to markdown and use this nice short hack!

![alt text](test.gif "Title")

Apache Commons

for (String code: ListUtils.emptyIfNull(codes)) {

}           

Google Guava

for (String code: Optional.of(codes).get()) {

}

To print 'item1' , 'item2', this code would work.

var myarray = ['hello', ' hello again'];

for (var item in myarray) {
    console.log(myarray[item])
}

You didn't tell who called setTimeout

Here how you call timeout without calling additional functions.

1. You can do this without making additional functions.

setTimeout(this.setState.bind(this, {position:1}), 3000);

Uses function.prototype.bind()

setTimeout takes the location of the function and keeps it in the context.

2. Another way to do the same even by writing even less code.

setTimeout(this.setState, 3000, {position:1});

Probably uses the same bind method at some point

The setTimeout only takes the location of the function and the function already has the context? Anyway, it works!

NOTE: These work with any function you use in js.

The existing answers are good but don't cover what to do when a smart pointer is not the (complete) answer to the problem you are trying to solve.

Among other things (explained well in other answers) using a smart pointer is a possible solution to How do we use a abstract class as a function return type? which has been marked as a duplicate of this question. However, the first question to ask if tempted to specify an abstract (or in fact, any) base class as a return type in C++ is "what do you really mean?". There is a good discussion (with further references) of idiomatic object oriented programming in C++ (and how this is different to other languages) in the documentation of the boost pointer container library. In summary, in C++ you have to think about ownership. Which smart pointers help you with, but are not the only solution, or always a complete solution (they don't give you polymorphic copy) and are not always a solution you want to expose in your interface (and a function return sounds an awful lot like an interface). It might be sufficient to return a reference, for example. But in all of these cases (smart pointer, pointer container or simply returning a reference) you have changed the return from a value to some form of reference. If you really needed copy you may need to add more boilerplate "idiom" or move beyond idiomatic (or otherwise) OOP in C++ to more generic polymorphism using libraries like Adobe Poly or Boost.TypeErasure.

I think the regex / string parsing solutions are great, but for this particular context, it seems like it would make sense just to use java's url parser:

https://docs.oracle.com/javase/tutorial/networking/urls/urlInfo.html

Taken from that page:

import java.net.*;
import java.io.*;

public class ParseURL {
    public static void main(String[] args) throws Exception {

        URL aURL = new URL("http://example.com:80/docs/books/tutorial"
                           + "/index.html?name=networking#DOWNLOADING");

        System.out.println("protocol = " + aURL.getProtocol());
        System.out.println("authority = " + aURL.getAuthority());
        System.out.println("host = " + aURL.getHost());
        System.out.println("port = " + aURL.getPort());
        System.out.println("path = " + aURL.getPath());
        System.out.println("query = " + aURL.getQuery());
        System.out.println("filename = " + aURL.getFile());
        System.out.println("ref = " + aURL.getRef());
    }
}

yields the following:

protocol = http
authority = example.com:80
host = example.com
port = 80
path = /docs/books/tutorial/index.html
query = name=networking
filename = /docs/books/tutorial/index.html?name=networking
ref = DOWNLOADING

If you get the the text inside the element use

Text()

$(".element-classname").text();

In your code:

$('.HOEnZb').text();

if you want get all the data including html Tags use:

html()

 $(".element-classname").html();

In your code:

$('.HOEnZb').html();

Hope it helps:)

Edit:

use jquery plugin: jquery.sizes.js

$('img').margin() or $('img').padding()

return:

{bottom: 10 ,left: 4 ,top: 0 ,right: 5}

get value:

$('img').margin().top

You can use the sequence method list.extend to extend the list by multiple values from any kind of iterable, being it another list or any other thing that provides a sequence of values.

>>> lst = [1, 2]
>>> lst.append(3)
>>> lst.append(4)
>>> lst
[1, 2, 3, 4]

>>> lst.extend([5, 6, 7])
>>> lst.extend((8, 9, 10))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

>>> lst.extend(range(11, 14))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]

So you can use list.append() to append a single value, and list.extend() to append multiple values.

Try something like this

document.getElementById("vid-holder").style.width=300 + "px";

You can always get a list by running:

svn status --help

Something close to:

@Html.DropDownListFor(m => m.UserRole, 
   new SelectList(Model.Roles, "UserRoleId", "UserRole", Model.Roles.First().UserRoleId), 
   new { /* any html  attributes here */ }) 

You need a SelectList to populate the DropDownListFor. For any HTML attributes you need, you can add:

new { @class = "DropDown", @id = "dropdownUserRole" }

In my case I have just installed MySQL Workbench but after uninstalling MySQL Workbench and installing MySQL installer and is same for both 32 and 64 bit then after it working like a charm. Hope it could be useful.

Your variable declarations and their scope are correct. The problem you are facing is that the first AJAX request may take a little bit time to finish. Therefore, the second URL will be filled with the value of sID before the its content has been set. You have to remember that AJAX request are normally asynchronous, i.e. the code execution goes on while the data is being fetched in the background.

You have to nest the requests:

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   obj = name;   // sID is only now available!   sID = obj.id;   console.log(sID); }); 

• Put the second request into a function
• and let it accept sID as a parameter, so you don't have to declare it globally anymore! (Global variables are almost always evil!)
• Remove sID and obj variables - name.id is sufficient unless you really need the other variables outside the function.

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   // We don't need sID or obj here - name.id is sufficient   console.log(name.id);    doSecondRequest(name.id); });  /// TODO Choose a better name function doSecondRequest(sID) {   $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function(stats){         console.log(stats);   }); }

Basically, what you want is:

www.google.co.uk  -> google.co.uk  -> google
www.google.org    -> google.org    -> google
www.google.org.uk -> google.org.uk -> google

Optional:

www.google.com     -> google.com    -> www.google
images.google.com  -> google.com    -> images.google
mail.yahoo.co.uk   -> yahoo.co.uk   -> mail.yahoo

www.mail.yahoo.com -> yahoo.com     -> mail.yahoo

You don't need to construct an ever-changing regex as 99% of domains will be matched properly if you simply look at the 2nd last part of the name:

(co|com|gov|net|org)

If it is one of these, then you need to match 3 dots, else 2. Simple. Now, my regex wizardry is no match for that of some other SO'ers, so the best way I've found to achieve this is with some code, assuming you've already stripped off the path:

 my @d=split /\./,$domain;                # split the domain part into an array
 $c=@d;                                   # count how many parts
 $dest=$d[$c-2].'.'.$d[$c-1];             # use the last 2 parts
 if ($d[$c-2]=~m/(co|com|gov|net|org)/) { # is the second-last part one of these?
   $dest=$d[$c-3].'.'.$dest;              # if so, add a third part
 };
 print $dest;                             # show it

To just get the name, as per your question:

 my @d=split /\./,$domain;                # split the domain part into an array
 $c=@d;                                   # count how many parts
 if ($d[$c-2]=~m/(co|com|gov|net|org)/) { # is the second-last part one of these?
   $dest=$d[$c-3];                        # if so, give the third last
   $dest=$d[$c-4].'.'.$dest if ($c>3);    # optional bit
 } else {
   $dest=$d[$c-2];                        # else the second last
   $dest=$d[$c-3].'.'.$dest if ($c>2);    # optional bit 
 };
 print $dest;                             # show it

I like this approach because it's maintenance-free. Unless you want to validate that it's actually a legitimate domain, but that's kind of pointless because you're most likely only using this to process log files and an invalid domain wouldn't find its way in there in the first place.

If you'd like to match "unofficial" subdomains such as bozo.za.net, or bozo.au.uk, bozo.msf.ru just add (za|au|msf) to the regex.

I'd love to see someone do all of this using just a regex, I'm sure it's possible.

Disclaimer: it is not about xunit with visual studio 2015, but Visual Studio 2017 with a UWP unit test application (MSTest). I got to this thread searching the same thing so maybe someone else will do the same :)

The solution for me was to update the nuget packages for MSTest.TestAdapter and MSTest.TestFramework. It seems that when you create a unit test app for UWP you don't automatically get the latest versions.

$scope.printDiv = function(divName) {
  var printContents = document.getElementById(divName).innerHTML;
  var popupWin = window.open('', '_blank', 'width=300,height=300');
  popupWin.document.open();
  popupWin.document.write('<html><head><link rel="stylesheet" type="text/css" href="style.css" /></head><body onload="window.print()">' + printContents + '</body></html>');
  popupWin.document.close();
} 

One more solution able to control the how many decimal digits to print out based on needs (if you don't want to print redundant zero(s))

For example, if you have a vector as elements and would like to get sum of it

elements <- c(-1e-05, -2e-04, -3e-03, -4e-02, -5e-01, -6e+00, -7e+01, -8e+02)
sum(elements)
## -876.5432

Apparently, the last digital as 1 been truncated, the ideal result should be -876.54321, but if set as fixed printing decimal option, e.g sprintf("%.10f", sum(elements)), redundant zero(s) generate as -876.5432100000

Following the tutorial here: printing decimal numbers, if able to identify how many decimal digits in the certain numeric number, like here in -876.54321, there are 5 decimal digits need to print, then we can set up a parameter for format function as below:

decimal_length <- 5
formatC(sum(elements), format = "f", digits = decimal_length)
## -876.54321

We can change the decimal_length based on each time query, so it can satisfy different decimal printing requirement.

If you want to know the user version in your code, then you can use using app() helper function

app()->version();

It is defined in this file ../src/Illuminate/Foundation/Application.php

Hope it will help :)

Try this (DEMO link updated):

success: function (response) {
        var trHTML = '';
        $.each(response, function (i, item) {
            trHTML += '<tr><td>' + item.rank + '</td><td>' + item.content + '</td><td>' + item.UID + '</td></tr>';
        });
        $('#records_table').append(trHTML);
    }

Fiddle DEMO WITH AJAX

function poll(){
    $("ajax.php", function(data){
        //do stuff  
    }); 
}

setInterval(function(){ poll(); }, 5000);

You can use the following generic method for your purpose. It should solve your issue.

//Called method
-(NSMutableArray*)sortArrayList:(NSMutableArray*)arrDeviceList filterKeyName:(NSString*)sortKeyName ascending:(BOOL)isAscending{
    NSSortDescriptor *sorter = [[NSSortDescriptor alloc] initWithKey:sortKeyName ascending:isAscending];
    [arrDeviceList sortUsingDescriptors:[NSArray arrayWithObject:sorter]];
    return arrDeviceList;
}

//Calling method
[self sortArrayList:arrSomeList filterKeyName:@"anything like date,name etc" ascending:YES];

One reason is that it is easy to create a set from map:

s := map[int]bool{5: true, 2: true}
_, ok := s[6] // check for existence
s[8] = true // add element 
delete(s, 2) // remove element

Union

s_union := map[int]bool{}
for k, _ := range s1{
    s_union[k] = true
}
for k, _ := range s2{
    s_union[k] = true
}

Intersection

s_intersection := map[int]bool{}
for k,_ := range s1 { 
  if s2[k] {
    s_intersection[k] = true
  }
}

It is not really that hard to implement all other set operations.

This is tricky; the reason it's failing is that you can't position via margin or text-align while absolutely positioned.

If the image is alone in the div, then I recommend something like this:

.image_block {
    width: 175px;
    height: 175px;
    line-height: 175px;
    text-align: center;
    vertical-align: bottom;
}

You may need to stick the vertical-align call on the image instead; not really sure without testing it. Using vertical-align and line-height is going to treat you a lot better, though, than trying to mess around with absolute positioning.

JSON.stringify() Converts an object into a string.

JSON.parse() Converts a JSON string into an object.

You can't... an array's size is always fixed in Java. Typically instead of using an array, you'd use an implementation of List<T> here - usually ArrayList<T>, but with plenty of other alternatives available.

You can create an array from the list as a final step, of course - or just change the signature of the method to return a List<T> to start with.

Return false from the anonymous function:

$(xml).find("strengths").each(function() {
  // Code
  // To escape from this block based on a condition:
  if (something) return false;
});

From the documentation of the each method:

Returning 'false' from within the each function completely stops the loop through all of the elements (this is like using a 'break' with a normal loop). Returning 'true' from within the loop skips to the next iteration (this is like using a 'continue' with a normal loop).

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

 @Override
    public boolean onOptionsItemSelected(MenuItem item) {
         int id = item.getItemId();
         if (id == R.id.standingsButton) {
            startActivity(new Intent(MainActivity.this,StandingsActivity.class));
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

Post uses the message body to send the information back to the server, as opposed to Get, which uses the query string (everything after the question mark). It is possible to send both a Get query string and a Post message body in the same request, but that can get a bit confusing so is best avoided.

Generally, best practice dictates that you use Get when you want to retrieve data, and Post when you want to alter it. (These rules aren't set in stone, the specs don't forbid altering data with Get, but it's generally avoided on the grounds that you don't want people making changes just by clicking a link or typing a URL)

Conversely, you can use Post to retrieve data without changing it, but using Get means you can bookmark the page, or share the URL with other people, things you couldn't do if you'd used Post.

• http://en.wikipedia.org/wiki/GET_%28HTTP%29
• http://en.wikipedia.org/wiki/POST_%28HTTP%29

As for the actual format of the data sent in the message body, that's entirely up to the sender and is specified with the Content-Type header. If not specified, the default content-type for HTML forms is application/x-www-form-urlencoded, which means the server will expect the post body to be a string encoded in a similar manner to a GET query string. However this can't be depended on in all cases. RFC2616 says the following on the Content-Type header:

Any HTTP/1.1 message containing an entity-body SHOULD include a
Content-Type header field defining the media type of that body. If
and only if the media type is not given by a Content-Type field, the
recipient MAY attempt to guess the media type via inspection of its
content and/or the name extension(s) of the URI used to identify the
resource. If the media type remains unknown, the recipient SHOULD
treat it as type "application/octet-stream".

The aim of using StringBuilder, i.e reducing memory. Is it achieved?

No, not at all. That code is not using StringBuilder correctly. (I think you've misquoted it, though; surely there aren't quotes around id2 and table?)

Note that the aim (usually) is to reduce memory churn rather than total memory used, to make life a bit easier on the garbage collector.

Will that take memory equal to using String like below?

No, it'll cause more memory churn than just the straight concat you quoted. (Until/unless the JVM optimizer sees that the explicit StringBuilder in the code is unnecessary and optimizes it out, if it can.)

If the author of that code wants to use StringBuilder (there are arguments for, but also against; see note at the end of this answer), better to do it properly (here I'm assuming there aren't actually quotes around id2 and table):

StringBuilder sb = new StringBuilder(some_appropriate_size);
sb.append("select id1, ");
sb.append(id2);
sb.append(" from ");
sb.append(table);
return sb.toString();

Note that I've listed some_appropriate_size in the StringBuilder constructor, so that it starts out with enough capacity for the full content we're going to append. The default size used if you don't specify one is 16 characters, which is usually too small and results in the StringBuilder having to do reallocations to make itself bigger (IIRC, in the Sun/Oracle JDK, it doubles itself [or more, if it knows it needs more to satisfy a specific append] each time it runs out of room).

You may have heard that string concatenation will use a StringBuilder under the covers if compiled with the Sun/Oracle compiler. This is true, it will use one StringBuilder for the overall expression. But it will use the default constructor, which means in the majority of cases, it will have to do a reallocation. It's easier to read, though. Note that this is not true of a series of concatenations. So for instance, this uses one StringBuilder:

return "prefix " + variable1 + " middle " + variable2 + " end";

It roughly translates to:

StringBuilder tmp = new StringBuilder(); // Using default 16 character size
tmp.append("prefix ");
tmp.append(variable1);
tmp.append(" middle ");
tmp.append(variable2);
tmp.append(" end");
return tmp.toString();

So that's okay, although the default constructor and subsequent reallocation(s) isn't ideal, the odds are it's good enough — and the concatenation is a lot more readable.

But that's only for a single expression. Multiple StringBuilders are used for this:

String s;
s = "prefix ";
s += variable1;
s += " middle ";
s += variable2;
s += " end";
return s;

That ends up becoming something like this:

String s;
StringBuilder tmp;
s = "prefix ";
tmp = new StringBuilder();
tmp.append(s);
tmp.append(variable1);
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(" middle ");
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(variable2);
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(" end");
s = tmp.toString();
return s;

...which is pretty ugly.

It's important to remember, though, that in all but a very few cases it doesn't matter and going with readability (which enhances maintainability) is preferred barring a specific performance issue.

MVC- Architecture on Android Its Better to Follow Any MVP instead MVC in android. But still according to the answer to the question this can be solution

Description and Guidelines

     Controller -
        Activity can play the role.
        Use an application class to write the
        global methods and define, and avoid
        static variables in the controller label
    Model -
        Entity like - user, Product, and Customer class.
    View -
        XML layout files.
    ViewModel -
        Class with like CartItem and owner
        models with multiple class properties
    Service -
        DataService- All the tables which have logic
        to get the data to bind the models - UserTable,
        CustomerTable
        NetworkService - Service logic binds the
        logic with network call - Login Service
Helpers -
        StringHelper, ValidationHelper static
        methods for helping format and validation code.
SharedView - fragmets or shared views from the code
        can be separated here

AppConstant -
        Use the Values folder XML files
        for constant app level

NOTE 1:

Now here is the piece of magic you can do. Once you have classified the piece of code, write a base interface class like, IEntity and IService. Declare common methods. Now create the abstract class BaseService and declare your own set of methods and have separation of code.

NOTE 2: If your activity is presenting multiple models then rather than writing the code/logic in activity, it is better to divide the views in fragments. Then it's better. So in the future if any more model is needed to show up in the view, add one more fragment.

NOTE 3: Separation of code is very important. Every component in the architecture should be independent not having dependent logic. If by chance if you have something dependent logic, then write a mapping logic class in between. This will help you in the future.

I'm using:

SELECT CAST(SYSTIMESTAMP AT TIME ZONE 'UTC' AS DATE) FROM DUAL;

It's working fine for me.

You can use Alljoyn framework for Peer-to-Peer connectivity in Android. Its based on Ad-hoc networking and also Open source.

You can use list ?? Enumerable.Empty<Friend>(), or have FindFriends return Enumerable.Empty<Friend>()

I just timed some functions out of curiosity. In these tests I'm removing non-alphanumeric characters from the string string.printable (part of the built-in string module). The use of compiled '[\W_]+' and pattern.sub('', str) was found to be fastest.

$ python -m timeit -s \
     "import string" \
     "''.join(ch for ch in string.printable if ch.isalnum())" 
10000 loops, best of 3: 57.6 usec per loop

$ python -m timeit -s \
    "import string" \
    "filter(str.isalnum, string.printable)"                 
10000 loops, best of 3: 37.9 usec per loop

$ python -m timeit -s \
    "import re, string" \
    "re.sub('[\W_]', '', string.printable)"
10000 loops, best of 3: 27.5 usec per loop

$ python -m timeit -s \
    "import re, string" \
    "re.sub('[\W_]+', '', string.printable)"                
100000 loops, best of 3: 15 usec per loop

$ python -m timeit -s \
    "import re, string; pattern = re.compile('[\W_]+')" \
    "pattern.sub('', string.printable)" 
100000 loops, best of 3: 11.2 usec per loop

You can try:

#!/bin/bash
d=$(date +%Y-%m-%d)
echo "$d"

EDIT: Changed y to Y for 4 digit date as per QuantumFool's comment.

If 'created' is datetime type

SELECT * FROM users WHERE created < DATE_ADD(CURDATE(), INTERVAL 1 DAY);

CURDATE() means also '2013-05-09 00:00:00'

CREATE PROCEDURE [dbo].[Temp_Proc_Select_City]
    @StateId INT
AS  
        BEGIN       
            SELECT * FROM tbl_City 
                WHERE 
                @StateID = CASE WHEN ISNULL(@StateId,0) = 0 THEN 0 ELSE StateId END ORDER BY CityName
        END

Here's a compact way to do something different in all four cases:

if(empty($youtube)) {
    if(empty($link)) {
        # both empty
    } else {
        # only $youtube not empty
    }
} else {
    if(empty($link)) {
        # only $link empty
    } else {
        # both not empty
    }
}

If you want to use an expression instead, you can use ?: instead:

echo empty($youtube) ? ( empty($link) ? 'both empty' : 'only $youtube not empty' )
                     : ( empty($link) ? 'only $link empty' : 'both not empty' );

I used the same method mentioned by @S-T after the pip uninstall command. And even after that the I got the message that Django was already installed. So i deleted the 'Django-1.7.6.egg-info' folder from '/usr/lib/python2.7/dist-packages' and then it worked for me.

I've found quite straight forward solution, The idea is to copy repository and then just remove unnecessary part. This is how it works:

1) Clone a repository you'd like to split

git clone [email protected]:testrepo/test.git

2) Move to git folder

cd test/

2) Remove unnecessary folders and commit it

rm -r ABC/
git add .
enter code here
git commit -m 'Remove ABC'

3) Remove unnecessary folder(s) form history with BFG

cd ..
java -jar bfg.jar --delete-folders "{ABC}" test
cd test/
git reflog expire --expire=now --all && git gc --prune=now --aggressive

for multiply folders you can use comma

java -jar bfg.jar --delete-folders "{ABC1,ABC2}" metric.git

4) Check that history doesn't contains the files/folders you just deleted

git log --diff-filter=D --summary | grep delete

5) Now you have clean repository without ABC, so just push it into new origin

remote add origin [email protected]:username/new_repo
git push -u origin master

That's it. You can repeat the steps to get another repository,

just remove XY1,XY2 and rename XYZ -> ABC on step 3

wxWidgets is worth checking out. It is well supported on Ruby via wxRuby. For an example app, have a look at wxRIDE. See it compared to other toolkits. You might also want to check out Anvil, which is a sort of Rails-ish framework for working with wx. It looks moribund now, though.

2k20 update: use Josh's solution with URLSearchParams.toString().

Old answer:

Without jQuery

var params = {
    parameter1: 'value_1',
    parameter2: 'value 2',
    parameter3: 'value&3' 
};

var esc = encodeURIComponent;
var query = Object.keys(params)
    .map(k => esc(k) + '=' + esc(params[k]))
    .join('&');

For browsers that don't support arrow function syntax which requires ES5, change the .map... line to

    .map(function(k) {return esc(k) + '=' + esc(params[k]);})

Here's a solution that I've come up with. I paired up the LocationStrategy with the Router events. Using the LocationStrategy to set a boolean to know when a user's currently traversing through the browser history. This way, I don't have to store a bunch of URL and y-scroll data (which doesn't work well anyway, since each data is replaced based on URL). This also solves the edge case when a user decides to hold the back or forward button on a browser and goes back or forward multiple pages rather than just one.

P.S. I've only tested on the latest version of IE, Chrome, FireFox, Safari, and Opera (as of this post).

Hope this helps.

export class AppComponent implements OnInit {
  isPopState = false;

  constructor(private router: Router, private locStrat: LocationStrategy) { }

  ngOnInit(): void {
    this.locStrat.onPopState(() => {
      this.isPopState = true;
    });

    this.router.events.subscribe(event => {
      // Scroll to top if accessing a page, not via browser history stack
      if (event instanceof NavigationEnd && !this.isPopState) {
        window.scrollTo(0, 0);
        this.isPopState = false;
      }

      // Ensures that isPopState is reset
      if (event instanceof NavigationEnd) {
        this.isPopState = false;
      }
    });
  }
}

Have you taken a look at the Wikipedia entry for magic number?

It goes into a bit of detail about all of the ways the magic number reference is made. Here's a quote about magic number as a bad programming practice

The term magic number also refers to the bad programming practice of using numbers directly in source code without explanation. In most cases this makes programs harder to read, understand, and maintain. Although most guides make an exception for the numbers zero and one, it is a good idea to define all other numbers in code as named constants.

Adding to all the answers above (which is why I made it a community wiki), it is probably best to mark any input<type="text"> with tabindex="-1", especially if using readonly instead of disabled (and perhaps the <input type="file">, although it should be hidden, it is still in the document, apparently). Labels did not act correctly when using the tab / enter key combinations, but the button did. So if you are copying one of the other solutions on this page, you may want to make those changes.

Can you try the following?

psexec \\server cmd /c "echo . | powershell script.ps1"

Use DECIMAL(8,6) for latitude (90 to -90 degrees) and DECIMAL(9,6) for longitude (180 to -180 degrees). 6 decimal places is fine for most applications. Both should be "signed" to allow for negative values.

I catch the next case about cors. Maybe it will be useful to somebody. If you add feature 'WebDav Redirector' to your server, PUT and DELETE requests are failed.

So, you will need to remove 'WebDAVModule' from your IIS server:

• "In the IIS modules Configuration, loop up the WebDAVModule, if your web server has it, then remove it".

Or add to your config:

<system.webServer>
<modules>
  <remove name="WebDAVModule"/>
</modules>
<handlers>
  <remove name="WebDAV" />
  ...
</handlers>

I had a situation where I needed a separate but persistent name space. I used classes. I don't otherwise. Segregated but persistent names are closures.

>>> class f2:
...     def __init__(self):
...         self.a = 0
...     def __call__(self, arg):
...         self.a += arg
...         return(self.a)
...
>>> f=f2()
>>> f(2)
2
>>> f(2)
4
>>> f(4)
8
>>> f(8)
16

# **OR**
>>> f=f2() # **re-initialize**
>>> f(f(f(f(2)))) # **nested**
16

# handy in list comprehensions to accumulate values
>>> [f(i) for f in [f2()] for i in [2,2,4,8]][-1] 
16

Xcode 8. Swift Project - importing Objective C.

Things to know:

1. Bridging header file MUST be saved within the project's folder. (i.e. not saved at the same level that .xcodeproj is saved, but instead one level further down into the folders where all your swift and objective c files are saved). It can still find the file at the top level, but it will not correctly link and be able to import Objective C files into the bridging header file
2. Bridging header file can be named anything, as long as it's a .h header file
3. Be sure the path in Build Settings > Swift Compiler - General > Objective C Bridging Header is correctly pointing to you bridging header file that you made
4. IMPORTANT: if you're still getting "not found", try to first empty your bridging header file and erase any imports you currently have written there. Be sure that the bridging header file can be found first, then start to add objective c imports to that file. For some reason, it will kick back the same "not found" error even if it is found but it doesn't like the import your trying for some reason
5. You should not #import "MyBridgingHeaderFile.h" in any of your objective C files. This will also cause a "file not found" error
