Solved jQuery: Add element after another element

<script>
$( "p" ).append( "<strong>Hello</strong>" );
</script>

OR

<script type="text/javascript"> 
jQuery(document).ready(function(){
jQuery ( ".sidebar_cart" ) .append( "<a href='http://#'>Continue Shopping</a>" );
});
</script>

I managed to make it work with the following code:

event.preventDefault();
timeout(function () {
    $inputToFocus.focus();
}, 500);

I'm using AngularJS so I have created a directive which solved my problem:

Directive:

angular.module('directivesModule').directive('focusOnClear', [
    '$timeout',
    function (timeout) {
        return {
            restrict: 'A',
            link: function (scope, element, attrs) {
                var id = attrs.focusOnClear;
                var $inputSearchElement = $(element).parent().find('#' + id);
                element.on('click', function (event) {
                    event.preventDefault();
                    timeout(function () {
                        $inputSearchElement.focus();
                    }, 500);
                });
            }
        };
    }
]);

How to use the directive:

<div>
    <input type="search" id="search">
    <i class="icon-clear" ng-click="clearSearchTerm()" focus-on-clear="search"></i>
</div>

It looks like you are using jQuery, so I don't know if the directive is any help.

Begin by asking him this question: "What kinds of things do you want to do with your computer?"

Then choose a set of activities that fit his answer, and choose a language that allows those things to be done. All the better if it's a simple (or simplifiable) scripting environment (e.g. Applescript, Ruby, any shell (Ksh, Bash, or even .bat files).

The reasons are:

1. If he's interested in the results, he'll probably be more motivated than if you're having him count Fibonacci's rabbits.
2. If he's getting results he likes, he'll probably think up variations on the activities you create.
3. If you're teaching him, he's not pursuing a serious career (yet); there's always time to switch to "industrial strength" languages later.

Services are required to connect to the Service Control Manager and provide feedback at start up (ie. tell SCM 'I'm alive!'). That's why C# application have a different project template for services. You have two alternatives:

• wrapp your exe on srvany.exe, as described in KB How To Create a User-Defined Service
• have your C# app detect when is launched as a service (eg. command line param) and switch control to a class that inherits from ServiceBase and properly implements a service.

Well that's the best part about PDOs is that it's pretty easy to access any database. Provided you have installed those drivers, you should be able to just do:

$db = new PDO("sqlsrv:Server=YouAddress;Database=YourDatabase", "Username", "Password");

Try to execute the procedure like this,

var c refcursor;
execute pkg_name.get_user('14232', '15', 'TDWL', 'SA', 1, :c);
print c;

I have heard this argument too - from people who forgot to put an index on their foreign keys and then complained that certain operations were slow (because constraint checking could take advantage of any index). So to sum up: There is no good reason not to use foreign keys. All modern databases support cascaded deletes, so...

no need for the padding or the corners.

here's a sample:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
    <gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
        android:angle="270"/>
</shape>

Adding my two bits. I needed a busy-wait for testing purposes. I didn't want to split the code as that would be a lot of work, so a simple for did it for me.

for (var i=0;i<1000000;i++){                    
     //waiting
  }

I don't see any downside in doing this and it did the trick for me.

As described here, this is another approach that takes care of symlinks too:

 */
function xcopy($source, $dest, $permissions = 0755)
{
    $sourceHash = hashDirectory($source);
    // Check for symlinks
    if (is_link($source)) {
        return symlink(readlink($source), $dest);
    }

    // Simple copy for a file
    if (is_file($source)) {
        return copy($source, $dest);
    }

    // Make destination directory
    if (!is_dir($dest)) {
        mkdir($dest, $permissions);
    }

    // Loop through the folder
    $dir = dir($source);
    while (false !== $entry = $dir->read()) {
        // Skip pointers
        if ($entry == '.' || $entry == '..') {
            continue;
        }

        // Deep copy directories
        if($sourceHash != hashDirectory($source."/".$entry)){
             xcopy("$source/$entry", "$dest/$entry", $permissions);
        }
    }

    // Clean up
    $dir->close();
    return true;
}

// In case of coping a directory inside itself, there is a need to hash check the directory otherwise and infinite loop of coping is generated

function hashDirectory($directory){
    if (! is_dir($directory)){ return false; }

    $files = array();
    $dir = dir($directory);

    while (false !== ($file = $dir->read())){
        if ($file != '.' and $file != '..') {
            if (is_dir($directory . '/' . $file)) { $files[] = hashDirectory($directory . '/' . $file); }
            else { $files[] = md5_file($directory . '/' . $file); }
        }
    }

    $dir->close();

    return md5(implode('', $files));
}

I had a problem with the same symtoms. In my case, it turned out that my submit function was missing the "return" statement.

For example:

 $("#id_form").on("submit", function(){
   //Code: Action (like ajax...)
   return false;
 })

I was having the same error - ImportError: No module named PyQt4.QtGui. Instead of running your python file (which uses PyQt) on the terminal as -

python file_name.py

Run it with sudo privileges -

sudo python file_name.py

This worked for me!

I generally like the shorthand version:

if (!!wlocation) { window.location = wlocation; }

Well, you can't quite do it that way. PAGE.SIGN_CREATE will never return 1; it will return PAGE.SIGN_CREATE. That's the point of enumerated types.

However, if you're willing to add a few keystrokes, you can add fields to your enums, like this:

    public enum PAGE{
        SIGN_CREATE(0),
        SIGN_CREATE_BONUS(1),
        HOME_SCREEN(2),
        REGISTER_SCREEN(3);

        private final int value;

        PAGE(final int newValue) {
            value = newValue;
        }

        public int getValue() { return value; }
    }

And then you call PAGE.SIGN_CREATE.getValue() to get 0.

I believe this can help you:

$(document).ready(function(){
    var temp = {someKey:"temp value", otherKey:"other value", fooKey:"some value"};
    for (var key in temp) {
        alert('<option value=' + key + '>' + temp[key] + '</option>');
    }
});

In your controller, render the new action from your create action if validation fails, with an instance variable, @car populated from the user input (i.e., the params hash). Then, in your view, add a logic check (either an if block around the form or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car is set.

In some browsers, fonts are set explicit for textareas and inputs, so they don’t inherit the fonts from higher elements. So, I think you need to apply the font styles for each textarea and input in the document as well (not just the body).

One idea might be to add clases to the body, then use CSS to style the document accordingly.

Without seeing your code, it's hard to answer other than a stab in the dark. I would guess that the string you're passing to encodeURIComponent(), which is the correct method to use, is coming from the result of accessing the innerHTML property. The solution is to get the innerText/textContent property value instead:

var str, 
    el = document.getElementById("myUrl");

if ("textContent" in el)
    str = encodeURIComponent(el.textContent);
else
    str = encodeURIComponent(el.innerText);

If that isn't the case, you can use the replace() method to replace the HTML entity:

encodeURIComponent(str.replace(/&/g, "&"));

There is an issue with scroll direction: rtl. It seems the plugin doesn't support it correctly. Here is the fiddle: fiddle

Note that it works correctly in Chrome, but in all other popular browsers the top scroll bar direction remains left.

I stumbled upon this question trying to identify a clean way to join two assoc arrays.

I was trying to join two different tables that didn't have relationships to each other.

This is what I came up with for PDO Query joining two Tables. Samuel Cook is what identified a solution for me with the array_merge() +1 to him.

        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $sql = "SELECT * FROM ".databaseTbl_Residential_Prospects."";
        $ResidentialData = $pdo->prepare($sql);
        $ResidentialData->execute(array($lapi));
        $ResidentialProspects = $ResidentialData->fetchAll(PDO::FETCH_ASSOC);

        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        $sql = "SELECT * FROM ".databaseTbl_Commercial_Prospects."";
        $CommercialData = $pdo->prepare($sql);
        $CommercialData->execute(array($lapi));
        $CommercialProspects = $CommercialData->fetchAll(PDO::FETCH_ASSOC);

        $Prospects = array_merge($ResidentialProspects,$CommercialProspects);
        echo '<pre>';
        var_dump($Prospects);
        echo '</pre>';

Maybe this will help someone else out.

The below code gave best result for me.

TextView myTextview = (TextView) findViewById(R.id.my_text_view);
htmltext = <your html (markup) character>;
Spanned sp = Html.fromHtml(htmltext);
myTextview.setText(sp);

The same error occurs also when doing SELECT DISTINCT ..., <CLOB_column>, ....

If this CLOB column contains values shorter than limit for VARCHAR2 in all the applicable rows you may use to_char(<CLOB_column>) or concatenate results of multiple calls to DBMS_LOB.SUBSTR(<CLOB_column>, ...).

Method #1: CSS :focus pseudo-class

As pure CSS solution, you could achieve sort of the effect by using a tabindex attribute for the image, and :focus pseudo-class as follows:

<img class="crossRotate" src="http://placehold.it/100" tabindex="1" />

.crossRotate {
    outline: 0;
    /* other styles... */
}

.crossRotate:focus {
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
}

WORKING DEMO.

Note: Using this approach, the image gets rotated onclick (focused), to negate the rotation, you'll need to click somewhere out of the image (blured).

Method #2: Hidden input & :checked pseudo-class

This is one of my favorite methods. In this approach, there's a hidden checkbox input and a <label> element which wraps the image.

Once you click on the image, the hidden input is checked because of using for attribute for the label.

Hence by using the :checked pseudo-class and adjacent sibling selector +, we could get the image to be rotated:

<input type="checkbox" id="hacky-input">

<label for="hacky-input">
  <img class="crossRotate" src="http://placehold.it/100">
</label>

#hacky-input {
  display: none; /* Hide the input */
}

#hacky-input:checked + label img.crossRotate {
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
}

WORKING DEMO #1.

WORKING DEMO #2 (Applying the rotate to the label gives a better experience).

Method #3: Toggling a class via JavaScript

If using JavaScript/jQuery is an option, you could toggle a .active class by .toggleClass() to trigger the rotation effect, as follows:

$('.crossRotate').on('click', function(){
    $(this).toggleClass('active');
});

.crossRotate.active {
    /* vendor-prefixes here... */
    transform: rotate(45deg);
}

WORKING DEMO.

Python has a weak support for closure. To see what I mean take the following example of a counter using closure with JavaScript:

function initCounter(){
    var x = 0;
    function counter  () {
        x += 1;
        console.log(x);
    };
    return counter;
}

count = initCounter();

count(); //Prints 1
count(); //Prints 2
count(); //Prints 3

Closure is quite elegant since it gives functions written like this the ability to have "internal memory". As of Python 2.7 this is not possible. If you try

def initCounter():
    x = 0;
    def counter ():
        x += 1 ##Error, x not defined
        print x
    return counter

count = initCounter();

count(); ##Error
count();
count();

You'll get an error saying that x is not defined. But how can that be if it has been shown by others that you can print it? This is because of how Python it manages the functions variable scope. While the inner function can read the outer function's variables, it cannot write them.

This is a shame really. But with just read-only closure you can at least implement the function decorator pattern for which Python offers syntactic sugar.

Update

As its been pointed out, there are ways to deal with python's scope limitations and I'll expose some.

1. Use the global keyword (in general not recommended).

2. In Python 3.x, use the nonlocal keyword (suggested by @unutbu and @leewz)

3. Define a simple modifiable class Object

class Object(object):
    pass

and create an Object scope within initCounter to store the variables

def initCounter ():
    scope = Object()
    scope.x = 0
    def counter():
        scope.x += 1
        print scope.x

    return counter

Since scope is really just a reference, actions taken with its fields do not really modify scope itself, so no error arises.

4. An alternative way, as @unutbu pointed out, would be to define each variable as an array (x = [0]) and modify it's first element (x[0] += 1). Again no error arises because x itself is not modified.

5. As suggested by @raxacoricofallapatorius, you could make x a property of counter

def initCounter ():

    def counter():
        counter.x += 1
        print counter.x

    counter.x = 0
    return counter

You can do it via RegEx replacement. Here is an example:

-- Citations Per Year - Cited Publications main query. Includes list of unique associated core project numbers, ordered by core project number.
SELECT ptc.pmid AS pmid, ptc.pmc_id, ptc.pub_title AS pubtitle, ptc.author_list AS authorlist,
  ptc.pub_date AS pubdate,
  REGEXP_REPLACE( LISTAGG ( ppcc.admin_phs_org_code || 
    TO_CHAR(ppcc.serial_num,'FM000000'), ',') WITHIN GROUP (ORDER BY ppcc.admin_phs_org_code || 
    TO_CHAR(ppcc.serial_num,'FM000000')),
    '(^|,)(.+)(,\2)+', '\1\2')
  AS projectNum
FROM publication_total_citations ptc
  JOIN proj_paper_citation_counts ppcc
    ON ptc.pmid = ppcc.pmid
   AND ppcc.citation_year = 2013
  JOIN user_appls ua
    ON ppcc.admin_phs_org_code = ua.admin_phs_org_code
   AND ppcc.serial_num = ua.serial_num
   AND ua.login_id = 'EVANSF'
GROUP BY ptc.pmid, ptc.pmc_id, ptc.pub_title, ptc.author_list, ptc.pub_date
ORDER BY pmid;

For those who have mentioned a reconciliation as a potential future for Hudson and Jenkins, with the fact that Jenkins will be joining SPI, it is unlikely at this point they will reconcile.

Put your TableLayout inside a ScrollView Layout.That will solve your problem.

In the same way you are trying to run cron.php, you can run another PHP script. You will have to do so via the CLI interface though.

#!/usr/bin/env php
<?php
# This file would be say, '/usr/local/bin/run.php'
// code
echo "this was run from CRON";

Then, add an entry to the crontab:

* * * * * /usr/bin/php -f /usr/local/bin/run.php &> /dev/null

If the run.php script had executable permissions, it could be listed directly in the crontab, without the /usr/bin/php part as well. The 'env php' part, in the script, would find the appropriate program to actually run the PHP code. So, for the 'executable' version - add executable permission to the file:

chmod +x /usr/local/bin/run.php

and then, add the following entry into crontab:

* * * * * /usr/local/bin/run.php &> /dev/null

Here is how I got what I wanted.

First, made a button (in styles.xml):

<style name="Button">
    <item name="android:textColor">@color/white</item>
    <item name="android:padding">0dp</item>
    <item name="android:minWidth">88dp</item>
    <item name="android:minHeight">36dp</item>
    <item name="android:layout_margin">3dp</item>
    <item name="android:elevation">1dp</item>
    <item name="android:translationZ">1dp</item>
    <item name="android:background">@drawable/primary_round</item>
</style>

The ripple and background for the button, as a drawable primary_round.xml:

<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="@color/primary_600">
  <item>
    <shape xmlns:android="http://schemas.android.com/apk/res/android">
        <corners android:radius="1dp" />
        <solid android:color="@color/primary" />
    </shape>
  </item>
</ripple>

This added the ripple effect I was looking for.

var newTH = document.createElement('th');
newTH.setAttribute("onclick", "removeColumn(#)");
newTH.setAttribute("id", "#");

function removeColumn(#){
// remove column #
}

Put them into a list and use merge with Reduce

Reduce(function(x, y) merge(x, y, all=TRUE), list(df1, df2, df3))
#    id v1 v2 v3
# 1   1  1 NA NA
# 2  10  4 NA NA
# 3   2  3  4 NA
# 4  43  5 NA NA
# 5  73  2 NA NA
# 6  23 NA  2  1
# 7  57 NA  3 NA
# 8  62 NA  5  2
# 9   7 NA  1 NA
# 10 96 NA  6 NA

You can also use this more concise version:

Reduce(function(...) merge(..., all=TRUE), list(df1, df2, df3))

If you are going to call relative.py directly and i.e. if you really want to import from a top level module you have to explicitly add it to the sys.path list.
Here is how it should work:

# Add this line to the beginning of relative.py file
import sys
sys.path.append('..')

# Now you can do imports from one directory top cause it is in the sys.path
import parent

# And even like this:
from parent import Parent

If you think the above can cause some kind of inconsistency you can use this instead:

sys.path.append(sys.path[0] + "/..")

sys.path[0] refers to the path that the entry point was ran from.

It sounds like your application might gain advantage from the use of a Bloom Filter data structure.

In short, a bloom filter look-up can tell you very quickly if a value is DEFINITELY NOT present in a set. Otherwise, you can do a slower look-up to get the index of a value that POSSIBLY MIGHT BE in the list. So if your application tends to get the "not found" result much more often then the "found" result, you might see a speed up by adding a Bloom Filter.

For details, Wikipedia provides a good overview of how Bloom Filters work, and a web search for "python bloom filter library" will provide at least a couple useful implementations.

To read the file saved in assets folder

}

console.info(currencyFormat(2665));   // $2,665.00
console.info(currencyFormat(102665)); // $102,665.00

It's worth mentioning that in some cases

File myFolder = new File("directory"); 

doesn't point to the root elements. For example when you place your application on C: drive (C:\myApp.jar) then myFolder points to (windows)

C:\Users\USERNAME\directory

instead of

C:\Directory

i am just using below method to hide or view a button. hope it will help you. just updating status and adding hide css is enough for me

constructor(props) {
   super(props);
      this.state = {
      visibleStatus: false
   };
}
updateStatusOfVisibility () {
   this.setStatus({
      visibleStatus: true
   });
}
hideCancel() {
   this.setStatus({visibleStatus: false});
}

render(){
   return(
    <View>
        <TextInput
            onFocus={this.showCancel()}
            onChangeText={(text) => {this.doSearch({input: text}); this.updateStatusOfVisibility()}} />

         <TouchableHighlight style={this.state.visibleStatus ? null : { display: "none" }}
             onPress={this.hideCancel()}>
            <View>
                <Text style={styles.cancelButtonText}>Cancel</Text>
            </View>
        </TouchableHighlight>
     </View>)
}

Updated Answer:

If the left corner shows it is a "Miscellaneous Files" on Visual Studio, you will want to make sure the current file is included in the project or not first, otherwise, ReSharper has no way to figure out the shortcut or even work. Visual Studio sometimes will not include the files in csproj

For a similar application I had to wrap my data object with JSON.stringify() like this:

data: JSON.stringify({ 
  'foo': 'bar', 
  'ca$libri': 'no$libri'
}),

The API was working with a REST client but couldn't get it to function with jquery ajax in the browser. stringify was the solution.

Here is my solution.

 if (Build.VERSION.SDK_INT >= 24) {
        holder.notificationTitle.setText(Html.fromHtml(notificationSucces.getMessage(), Html.FROM_HTML_MODE_LEGACY));
    } else {
        holder.notificationTitle.setText(Html.fromHtml(notificationSucces.getMessage()));

    }

I think you are missing using System.Linq; from this system class.

and also add using System.Data.Entity; to the code

Float elements will be rendered at the line they are normally in the layout. To fix this, you have two choices:

Move the header and the p after the login box:

    <div class='hero-unit'>

        <div id='login-box' class='pull-right control-group'>
            <div class='clearfix'>
                <input type='text' placeholder='Username' />
            </div>
            <div class='clearfix'>
                <input type='password' placeholder='Password' />
            </div>
            <button type='button' class='btn btn-primary'>Log in</button>
        </div>

        <h2>Welcome</h2>

        <p>Please log in</p>

    </div>
</div>

Or enclose the left block in a pull-left div, and add a clearfix at the bottom

<div class='container'>
    <div class='hero-unit'>

        <div class="pull-left">

          <h2>Welcome</h2>

          <p>Please log in</p>

        </div>

        <div id='login-box' class='pull-right control-group'>
            <div class='clearfix'>
                <input type='text' placeholder='Username' />
            </div>
            <div class='clearfix'>
                <input type='password' placeholder='Password' />
            </div>
            <button type='button' class='btn btn-primary'>Log in</button>
        </div>

        <div class="clearfix"></div>

    </div>
</div>

Here is the basic example to demonstrate the Python string formatting and a new way to do it.

my_word = 'epic'
my_number = 1

print('The %s number is %d.' % (my_word, my_number))  # traditional substitution with % operator

//The epic number is 1.

print(f'The {my_word} number is {my_number}.')  # newer format string style

//The epic number is 1.

Both prints the same.

I had to sort out capitalisation of my service reference, delete the references and re add them to fix this. I am not sure if any of these steps are superstitious, but the problem went away.

When an element, such as a div is floated, its parent container no longer considers its height, i.e.

<div id="main">
  <div id="child" style="float:left;height:40px;"> Hi</div>
</div>

The parent container will not be be 40 pixels tall by default. This causes a lot of weird little quirks if you're using these containers to structure layout.

So the clearfix class that various frameworks use fixes this problem by making the parent container "acknowledge" the contained elements.

Day to day, I normally just use frameworks such as 960gs, Twitter Bootstrap for laying out and not bothering with the exact mechanics.

It could be that Pytest is not reading the package as a Python module while Python is (likely due to path issues). Try changing the directory of the pytest script or adding the module explicitly to your PYTHONPATH.

Or it could be that you have two versions of Python installed on your machine. Check your Python source for pytest and for the python shell that you run. If they are different (i.e. Python 2 vs 3), use source activate to make sure that you are running the pytest installed for the same python that the module is installed in.

I was also suffering from the same issue. Finally I resolved it by setting binary value in capabilites as shown below. At run time it uses this value so it is must to set.

DesiredCapabilities capability = DesiredCapabilities.firefox();
capability.setCapability("platform", Platform.ANY);
capability.setCapability("binary", "/ms/dist/fsf/PROJ/firefox/16.0.0/bin/firefox"); //for linux

//capability.setCapability("binary", "C:\\Program Files\\Mozilla  Firefox\\msfirefox.exe"); //for windows                
WebDriver    currentDriver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capability);

And you are done!!! Happy coding :)

Secondary data files are optional, are user-defined, and store user data. Secondary files can be used to spread data across multiple disks by putting each file on a different disk drive. Additionally, if a database exceeds the maximum size for a single Windows file, you can use secondary data files so the database can continue to grow.

Source: MSDN: Understanding Files and Filegroups

The recommended file name extension for secondary data files is .ndf, but this is not enforced.

Using append function to generate first 100 elements.

def generate():
    series = [0, 1]
    for i in range(0, 100):
        series.append(series[i] + series[i+1])

    return series


print(generate())

There is no space allocated for the strings. use array (or) pointers with malloc() and free()

Other than that

#import <stdio.h>
#import <string.h>

should be

#include <stdio.h>
#include <string.h>

NOTE:

• anything that is malloc()ed must be free()'ed
• you need to allocate n + 1 bytes for a string which is of length n (the last byte is for \0)

Please you the following code as a reference

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main(int argc, char *argv[])
{
    //char *str1 = "First string";
    char *str1 = "First string is a big string";
    char *str2 = NULL;

    if ((str2 = (char *) malloc(sizeof(char) * strlen(str1) + 1)) == NULL) {
        printf("unable to allocate memory \n");
        return -1; 
    }   

    strcpy(str2, str1);

    printf("str1 : %s \n", str1);
    printf("str2 : %s \n", str2);

    free(str2);
    return 0;
}

To get back to the parent frame, use:

driver.switchTo().parentFrame();

To get back to the first/main frame, use:

driver.switchTo().defaultContent();

Convert file format to png

string newfilename ,

If you just want to add a string to it, the simple answer is:

ListBox.Items.Add("some text");

Linq With Or Condition by using Lambda expression you can do as below

DataTable dtEmp = new DataTable();

dtEmp.Columns.Add("EmpID", typeof(int));
dtEmp.Columns.Add("EmpName", typeof(string));
dtEmp.Columns.Add("Sal", typeof(decimal));
dtEmp.Columns.Add("JoinDate", typeof(DateTime));
dtEmp.Columns.Add("DeptNo", typeof(int));

dtEmp.Rows.Add(1, "Rihan", 10000, new DateTime(2001, 2, 1), 10);
dtEmp.Rows.Add(2, "Shafi", 20000, new DateTime(2000, 3, 1), 10);
dtEmp.Rows.Add(3, "Ajaml", 25000, new DateTime(2010, 6, 1), 10);
dtEmp.Rows.Add(4, "Rasool", 45000, new DateTime(2003, 8, 1), 20);
dtEmp.Rows.Add(5, "Masthan", 22000, new DateTime(2001, 3, 1), 20);


var res2 = dtEmp.AsEnumerable().Where(emp => emp.Field<int>("EmpID")
            == 1 || emp.Field<int>("EmpID") == 2);

foreach (DataRow row in res2)
{
    Label2.Text += "Emplyee ID: " + row[0] + "   &   Emplyee Name: " + row[1] + ",  ";
}

You have root, but you still need to remount /system to be read/write

$ adb shell
$ su
$ mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system

You can use the Distinct method to return an IEnumerable<T> of distinct items:

var uniqueItems = yourList.Distinct();

And if you need the sequence of unique items returned as a List<T>, you can add a call to ToList:

var uniqueItemsList = yourList.Distinct().ToList();

Virtual Function Tables

Let's begin with some background on virtual function tables and how they work (source):

[20.3] What's the difference between how virtual and non-virtual member functions are called?

Non-virtual member functions are resolved statically. That is, the member function is selected statically (at compile-time) based on the type of the pointer (or reference) to the object.

In contrast, virtual member functions are resolved dynamically (at run-time). That is, the member function is selected dynamically (at run-time) based on the type of the object, not the type of the pointer/reference to that object. This is called "dynamic binding." Most compilers use some variant of the following technique: if the object has one or more virtual functions, the compiler puts a hidden pointer in the object called a "virtual-pointer" or "v-pointer." This v-pointer points to a global table called the "virtual-table" or "v-table."

The compiler creates a v-table for each class that has at least one virtual function. For example, if class Circle has virtual functions for draw() and move() and resize(), there would be exactly one v-table associated with class Circle, even if there were a gazillion Circle objects, and the v-pointer of each of those Circle objects would point to the Circle v-table. The v-table itself has pointers to each of the virtual functions in the class. For example, the Circle v-table would have three pointers: a pointer to Circle::draw(), a pointer to Circle::move(), and a pointer to Circle::resize().

During a dispatch of a virtual function, the run-time system follows the object's v-pointer to the class's v-table, then follows the appropriate slot in the v-table to the method code.

The space-cost overhead of the above technique is nominal: an extra pointer per object (but only for objects that will need to do dynamic binding), plus an extra pointer per method (but only for virtual methods). The time-cost overhead is also fairly nominal: compared to a normal function call, a virtual function call requires two extra fetches (one to get the value of the v-pointer, a second to get the address of the method). None of this runtime activity happens with non-virtual functions, since the compiler resolves non-virtual functions exclusively at compile-time based on the type of the pointer.

My problem, or how I came here

I'm attempting to use something like this now for a cubefile base class with templated optimized load functions which will be implemented differently for different types of cubes (some stored by pixel, some by image, etc).

Some code:

virtual void  LoadCube(UtpBipCube<float> &Cube,long LowerLeftRow=0,long LowerLeftColumn=0,
        long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1) = 0;
virtual void  LoadCube(UtpBipCube<short> &Cube, long LowerLeftRow=0,long LowerLeftColumn=0,
        long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1) = 0;
virtual void  LoadCube(UtpBipCube<unsigned short> &Cube, long LowerLeftRow=0,long LowerLeftColumn=0,
        long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1) = 0;

What I'd like it to be, but it won't compile due to a virtual templated combo:

template<class T>
    virtual void  LoadCube(UtpBipCube<T> &Cube,long LowerLeftRow=0,long LowerLeftColumn=0,
            long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1) = 0;

I ended up moving the template declaration to the class level. This solution would have forced programs to know about specific types of data they would read before they read them, which is unacceptable.

Solution

warning, this isn't very pretty but it allowed me to remove repetitive execution code

1) in the base class

virtual void  LoadCube(UtpBipCube<float> &Cube,long LowerLeftRow=0,long LowerLeftColumn=0,
            long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1) = 0;
virtual void  LoadCube(UtpBipCube<short> &Cube, long LowerLeftRow=0,long LowerLeftColumn=0,
            long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1) = 0;
virtual void  LoadCube(UtpBipCube<unsigned short> &Cube, long LowerLeftRow=0,long LowerLeftColumn=0,
            long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1) = 0;

2) and in the child classes

void  LoadCube(UtpBipCube<float> &Cube, long LowerLeftRow=0,long LowerLeftColumn=0,
        long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1)
{ LoadAnyCube(Cube,LowerLeftRow,LowerLeftColumn,UpperRightRow,UpperRightColumn,LowerBand,UpperBand); }

void  LoadCube(UtpBipCube<short> &Cube, long LowerLeftRow=0,long LowerLeftColumn=0,
        long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1)
{ LoadAnyCube(Cube,LowerLeftRow,LowerLeftColumn,UpperRightRow,UpperRightColumn,LowerBand,UpperBand); }

void  LoadCube(UtpBipCube<unsigned short> &Cube, long LowerLeftRow=0,long LowerLeftColumn=0,
        long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1)
{ LoadAnyCube(Cube,LowerLeftRow,LowerLeftColumn,UpperRightRow,UpperRightColumn,LowerBand,UpperBand); }

template<class T>
void  LoadAnyCube(UtpBipCube<T> &Cube, long LowerLeftRow=0,long LowerLeftColumn=0,
        long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1);

Note that LoadAnyCube is not declared in the base class.

Here's another stack overflow answer with a work around: need a virtual template member workaround.

As jeb noted, the rest of the loop is skipped but evaluated, which makes the FOR solution too slow for this purpose. An alternative:

set F=1
:nextpart
if not exist "%F%" goto :EOF
echo %F%
set /a F=%F%+1
goto nextpart

You might need to use delayed expansion and call subroutines when using this in loops.

out.write(c.toString());
out.newLine();

here is a simple solution, I hope it works

EDIT: I was using "\n" which was obviously not recommended approach, modified answer.

EXEC sp_helplogins

You can also pass an "@LoginNamePattern" parameter to get information about a specific login:

EXEC sp_helplogins @LoginNamePattern='fred'

Take a look at FileSaver.js. It provides a handy saveAs function which takes care of most browser specific quirks.

update for Angular 1.2+ (v1.2.6 at the time of this post):

.stuff-to-show {
  position: relative;
  height: 100px;
  -webkit-transition: top linear 1.5s;
  transition: top linear 1.5s;
  top: 0;
}
.stuff-to-show.ng-hide {
  top: -100px;
}
.stuff-to-show.ng-hide-add,
.stuff-to-show.ng-hide-remove {
  display: block!important;
}

(plunker)

For me running these three commands fix the issue on my Mac:

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

For ease of copying here's one-liner

export ANDROID_HOME=~/Library/Android/sdk && export PATH=${PATH}:${ANDROID_HOME}/tools && export PATH=${PATH}:${ANDROID_HOME}/platform-tools

To add Permanently

Follow these steps:

1. Open the .bash_profile file in your home directory (for example, /Users/your-user-name/.bash_profile) in a text editor.
2. Add export PATH="The above exports here" to the last line of the file, where your-dir is the directory you want to add.
3. Save the .bash_profile file.
4. Restart your terminal

Adding to bash process for different systems

There are several ways, like:

where some_column is null or some_column = ''

or

where ifnull(some_column, '') = ''

or

where coalesce(some_column, '') = ''

of

where ifnull(length(some_column), 0) = 0

Here's a cross browser working function (usable for other than click handlers too):

function eventFire(el, etype){
    if (el.fireEvent) {
      el.fireEvent('on' + etype);
    } else {
      var evObj = document.createEvent('Events');
      evObj.initEvent(etype, true, false);
      el.dispatchEvent(evObj);
    }
}

The spec says seconds:

http://tools.ietf.org/html/draft-ietf-oauth-v2-22#section-4.2.2

expires_in
    OPTIONAL.  The lifetime in seconds of the access token.  For
    example, the value "3600" denotes that the access token will
    expire in one hour from the time the response was generated.

I agree with OP that it's careless for Google to not document this.

RMI is based on Proxy.

Should be possible to cite one for most of the 23 patterns in GoF:

1. Abstract Factory: java.sql interfaces all get their concrete implementations from JDBC JAR when driver is registered.
2. Builder: java.lang.StringBuilder.
3. Factory Method: XML factories, among others.
4. Prototype: Maybe clone(), but I'm not sure I'm buying that.
5. Singleton: java.lang.System
6. Adapter: Adapter classes in java.awt.event, e.g., WindowAdapter.
7. Bridge: Collection classes in java.util. List implemented by ArrayList.
8. Composite: java.awt. java.awt.Component + java.awt.Container
9. Decorator: All over the java.io package.
10. Facade: ExternalContext behaves as a facade for performing cookie, session scope and similar operations.
11. Flyweight: Integer, Character, etc.
12. Proxy: java.rmi package
13. Chain of Responsibility: Servlet filters
14. Command: Swing menu items
15. Interpreter: No directly in JDK, but JavaCC certainly uses this.
16. Iterator: java.util.Iterator interface; can't be clearer than that.
17. Mediator: JMS?
18. Memento:
19. Observer: java.util.Observer/Observable (badly done, though)
20. State:
21. Strategy:
22. Template:
23. Visitor:

I can't think of examples in Java for 10 out of the 23, but I'll see if I can do better tomorrow. That's what edit is for.

You would need to create a generic class named MyProp. Then, you will need to add implicit or explicit cast operators so you can get and set the value as if it were the type specified in the generic type parameter. These cast operators can do the extra work that you need.

Just extending Barnards's answer with commons-io. Separate answer because I can not format code in comments.

InputStream is = null;
try {
  is = url.openStream ();
  byte[] imageBytes = IOUtils.toByteArray(is);
}
catch (IOException e) {
  System.err.printf ("Failed while reading bytes from %s: %s", url.toExternalForm(), e.getMessage());
  e.printStackTrace ();
  // Perform any other exception handling that's appropriate.
}
finally {
  if (is != null) { is.close(); }
}

I had the same problem. It turned out that I didn't specify a default page and I didn't have any page that is named after the default page convention (default.html, defult.aspx etc). As a result, ASP.NET doesn't allow the user to browse the directory (not a problem in Visual Studio built-in web server that allows you to view the directory) and shows the error message. To fix it, I added one default page in Web.Config and it worked.

<system.webServer>
    <defaultDocument>
        <files>
            <add value="myDefault.aspx"/>
        </files>
    </defaultDocument>
</system.webServer>

Use Manatee.Json https://github.com/gregsdennis/Manatee.Json/wiki/Usage

And you can convert the entire object to a string, filename.json is expected to be located in documents folder.

        var text = File.ReadAllText("filename.json");
        var json = JsonValue.Parse(text);

        while (JsonValue.Null != null)
        {
            Console.WriteLine(json.ToString());

        }
        Console.ReadLine();

The RequestContext is deprecated from Primefaces 6.2. From this version use the following:

if (componentID != null && PrimeFaces.current().isAjaxRequest()) {
    PrimeFaces.current().ajax().update(componentID);
}

And to execute javascript from the backbean use this way:

PrimeFaces.current().executeScript(jsCommand);

Reference:

• https://forum.primefaces.org/viewtopic.php?t=53129

In this case, the selecteditem bind doesn't work, because the hash id of the objects are different.

One possible solution is:

Based on the selected item id, recover the object on the itemsource collection and set the selected item property to with it.

Example:

<ctrls:ComboBoxControlBase SelectedItem="{Binding Path=SelectedProfile, Mode=TwoWay}" ItemsSource="{Binding Path=Profiles, Mode=OneWay}" IsEditable="False" DisplayMemberPath="Name" />

The Property binded to ItemSource is:

public ObservableCollection<Profile> Profiles
{
   get { return this.profiles; }
   private set { profiles = value; RaisePropertyChanged("Profiles"); }
}

The property binded to SelectedItem is:

public Profile SelectedProfile 
{
    get { return selectedProfile; }
    set
    {
        if (this.SelectedUser != null)
        {
            this.SelectedUser.Profile = value; 
            RaisePropertyChanged("SelectedProfile");  
        } 
    } 
}

The recovery code is:

    [Command("SelectionChanged")]
    public void SelectionChanged(User selectedUser)
    {
        if (selectedUser != null)
        {
            if (selectedUser is User)
            {
                if (selectedUser.Profile != null)
                {
                    this.SelectedUser = selectedUser;
                    this.selectedProfile = this.Profiles.Where(p => p.Id == this.SelectedUser.Profile.Id).FirstOrDefault();
                    MessageBroker.Instance.NotifyColleagues("ShowItemDetails"); 
                }
            }
        }            
    }

I hope it helps you. I spent a lot of my time searching for answers, but I couldn´t find.

I created a jQuery version of PhpMyCoder's answer:

$('form').submit(function( e ) {    
    if(!($('#file')[0].files[0].size < 10485760 && get_extension($('#file').val()) == 'jpg')) { // 10 MB (this size is in bytes)
        //Prevent default and display error
        alert("File is wrong type or over 10Mb in size!");
        e.preventDefault();
    }
});

function get_extension(filename) {
    return filename.split('.').pop().toLowerCase();
}

This is one "trick" you can do since your out of an async function so can't use await keywork

Do what you want to do with vm.feed inside a setTimeout

vm.feed = getFeed().then(function(data) {return data;});

 setTimeout(() => {
    // do you stuf here
    // after the time you promise will be revolved or rejected
    // if you need some of the values in here immediately out of settimeout
    // might occur an error if promise wore not yet resolved or rejected
    console.log("vm.feed",vm.feed);
 }, 100);

                    .setStyle(NotificationCompat.BigTextStyle().bigText(message))
                    .setSound(soundUri)
                    .setContentIntent(pendingIntent)


            val random = Random()
            val id = random.nextInt()
            notificationManager.notify(id, notificationBuilder.build())

        }



    }

If you want to intelligently handle missing parameters you can do something like:

IF %1.==. GOTO No1
IF %2.==. GOTO No2
... do stuff...
GOTO End1

:No1
  ECHO No param 1
GOTO End1
:No2
  ECHO No param 2
GOTO End1

:End1

You can use:

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

    if (mServiceConn != null) {
        unbindService(mServiceConn);
    }
}

One more method through exec().

exec('/usr/bin/httpd -M | find "rewrite_module"',$output);

If mod_rewrite is loaded it will return "rewrite_module" in output.

CDATA (Character DATA): It is similarly to a comment but it is part of document. i.e. CDATA is a data, it is part of the document but the data can not parsed in XML.
Note: XML comment omits while parsing an XML but CDATA shows as it is.

PCDATA (Parsed Character DATA) :By default, everything is PCDATA. PCDATA is a data, it can be parsed in XML.

Make sure that your connection charset to MySQL is UTF-8. It often defaults to ISO-8859-1 which means that the MySQL driver will convert the text to ISO-8859-1.

You can set the connection charset with mysql_set_charset, mysqli_set_charset or with the query SET NAMES 'utf-8'

There important changes to the Connector/J API going from version 5.1 to 8.0. You might need to adjust your API calls accordingly if the version you are using falls above 5.1.

please visit MySQL on the following link for more information https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-api-changes.html

SELECT DEPTNAME
FROM(SELECT D.DEPTNAME,COUNT(EMPID) AS TOTEMP
     FROM DEPT AS D,EMPLOYEE AS E
     WHERE D.DEPTID=E.DEPTID AND SALARY>1000
     GROUP BY D.DEPTID
     )
WHERE TOTEMP>2;

Due to the above mentioned problems, I prefer table value functions.

If you have this:

CREATE VIEW [dbo].[MyView] AS SELECT A, B FROM dbo.Something

create this:

CREATE FUNCTION MyFunction() RETURNS TABLE AS RETURN (SELECT * FROM [dbo].[MyView])

Then you simply import the function rather than the view.

You can also do this with ant contrib's if task.

<if>
    <equals arg1="${condition}" arg2="true"/>
    <then>
        <copy file="${some.dir}/file" todir="${another.dir}"/>
    </then>
    <elseif>
        <equals arg1="${condition}" arg2="false"/>
        <then>
            <copy file="${some.dir}/differentFile" todir="${another.dir}"/>
        </then>
    </elseif>
    <else>
        <echo message="Condition was neither true nor false"/>
    </else>
</if>

If you want to check repetition more than 1 in descending order then implement below query.

SELECT   duplicate_data,COUNT(duplicate_data) AS duplicate_data
FROM     duplicate_data_table_name 
GROUP BY duplicate_data
HAVING   COUNT(duplicate_data) > 1
ORDER BY COUNT(duplicate_data) DESC

If want simple count query.

SELECT   COUNT(duplicate_data) AS duplicate_data
FROM     duplicate_data_table_name 
GROUP BY duplicate_data
ORDER BY COUNT(duplicate_data) DESC

Use IsNumeric. It returns true if it's a number or false otherwise.

Public Sub NumTest()
    On Error GoTo MyErrorHandler

    Dim myVar As Variant
    myVar = 11.2 'Or whatever

    Dim finalNumber As Integer
    If IsNumeric(myVar) Then
        finalNumber = CInt(myVar)
    Else
        finalNumber = 0
    End If

    Exit Sub

MyErrorHandler:
    MsgBox "NumTest" & vbCrLf & vbCrLf & "Err = " & Err.Number & _
        vbCrLf & "Description: " & Err.Description
End Sub

Do just simple thing:

1. Open git-hub (Shell) and navigate to the directory file belongs to (cd /a/b/c/...)
2. Execute dos2unix (sometime dos2unix.exe)
3. Try commit now. If you get same error again. Perform all above steps except instead of dos2unix, do unix2dox (unix2dos.exe sometime)

Firstly for technical accuracy, border-radius is not a HTML5 feature, it's a CSS3 feature.

The best script I've found to render box shadows & rounded corners in older IE versions is IE-CSS3. It translates CSS3 syntax into VML (an IE-specific Vector language like SVG) and renders them on screen.

It works a lot better on IE7-8 than on IE6, but does support IE6 as well. I didn't think much to PIE when I used it and found that (like HTC) it wasn't really built to be functional.

If you want your result concatenated, as you show in your question, you could try something like:

>>> reduce(lambda x, y: str(x)+str(y), map(ord,"hello world"))
'10410110810811132119111114108100'

You can use Object.keys(), "which returns an array of a given object's own enumerable property names, in the same order as we get with a normal loop."

You can use any object in place of stats:

var stats = {_x000D_
  a: 3,_x000D_
  b: 6,_x000D_
  d: 7,_x000D_
  erijgolekngo: 35_x000D_
}_x000D_
/*  this is the answer here  */_x000D_
for (var key in Object.keys(stats)) {_x000D_
  var t = Object.keys(stats)[key];_x000D_
  console.log(t + " value =: " + stats[t]);_x000D_
}

Let us say we have a project social_login. To check the traffic to your repo, you can goto https://github.com//social_login/graphs/traffic

Above answers are very elegant. I have written this function long back where i was also struggling to concatenate two dataframe with distinct columns.

Suppose you have dataframe sdf1 and sdf2

from pyspark.sql import functions as F
from pyspark.sql.types import *

def unequal_union_sdf(sdf1, sdf2):
    s_df1_schema = set((x.name, x.dataType) for x in sdf1.schema)
    s_df2_schema = set((x.name, x.dataType) for x in sdf2.schema)

    for i,j in s_df2_schema.difference(s_df1_schema):
        sdf1 = sdf1.withColumn(i,F.lit(None).cast(j))

    for i,j in s_df1_schema.difference(s_df2_schema):
        sdf2 = sdf2.withColumn(i,F.lit(None).cast(j))

    common_schema_colnames = sdf1.columns
    sdk = \
        sdf1.select(common_schema_colnames).union(sdf2.select(common_schema_colnames))
    return sdk 

sdf_concat = unequal_union_sdf(sdf1, sdf2) 

echo will normally output a newline, which is suppressed with -n. Try this:

echo -n foobar | sha256sum

I just leave my solution here.

import csv
import numpy as np

with open(name, newline='') as f:
    reader = csv.reader(f, delimiter=",")
    # skip header
    next(reader)
    # convert csv to list and then to np.array
    data  = np.array(list(reader))[:, 1:] # skip the first column

print(data.shape) # => (N, 2)

# sum each row
s = data.sum(axis=1)
print(s.shape) # => (N,)

Or use a fancy list comprehension, which are supposed to be "computationally more efficient", when working with very very large files/lists

fd = open(filename,'r')
chars = [c for line in fd for c in line if c is not " "]
fd.close()

Btw: The answer that was accepted does not account for the whitespaces...

Casting will ignore anything after the decimal point, so 8.6 becomes 8.

Convert.ToInt32(8.6) is the safe way to ensure your double gets rounded to the nearest integer, in this case 9.

I hope my encoding here is right ;D To make it faster just use the ugly getInstance() call of GregorianCalendar instead of constructor call:

import java.util.GregorianCalendar;
import javax.xml.datatype.DatatypeFactory;
import javax.xml.datatype.XMLGregorianCalendar;

public class DateTest {

   public static void main(final String[] args) throws Exception {
      // do not forget the type cast :/
      GregorianCalendar gcal = (GregorianCalendar) GregorianCalendar.getInstance();
      XMLGregorianCalendar xgcal = DatatypeFactory.newInstance()
            .newXMLGregorianCalendar(gcal);
      System.out.println(xgcal);
   }

$client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC);

$client->on("connect", function($cli) {

});

$client->on("receive", function($cli, $data){
    echo "Receive: $data\n";
});

$client->on("error", function($cli){
    echo "connect fail\n";
});

$client->on("close", function($cli){
    echo "close\n";
});

$client->connect('127.0.0.1', 9501, 0.5);

If anyone is trying to solve this on a 64-bit version of Windows, you might need to create the following key:

If you wish to stream the CSV out to the user without creating a file then I found the following to be the simplest method. You can use any extension/method to create the ToCsv() function (which returns a string based on the given DataTable).

        var report = myDataTable.ToCsv();
        var bytes = Encoding.GetEncoding("iso-8859-1").GetBytes(report);

        Response.Buffer = true;
        Response.Clear();
        Response.AddHeader("content-disposition", "attachment; filename=report.csv");
        Response.ContentType = "text/csv";
        Response.BinaryWrite(bytes);
        Response.End();

You need to set the text to something other than an empty string. In addition, the .html() function should do it while preserving the HTML structure of the div.

$('#one').html($('#one').html().replace('text','replace'));

This is an alternative way of deleting records without leaving orphans.

Declare @user Table(keyValue int  , someString varchar(10))
insert into @user
values(1,'1 value')

insert into @user
values(2,'2 value')

insert into @user
values(3,'3 value')

Declare @password Table(  keyValue int , details varchar(10))
insert into @password
values(1,'1 Password')
insert into @password
values(2,'2 Password')
insert into @password
values(3,'3 Password')

        --before deletion
  select * from @password a inner join @user b
                on a.keyvalue = b.keyvalue
  select * into #deletedID from @user where keyvalue=1 -- this works like the output example
  delete  @user where keyvalue =1
  delete @password where keyvalue in (select keyvalue from #deletedid)

  --After deletion--
  select * from @password a inner join @user b
                on a.keyvalue = b.keyvalue

Here is a simple example that should let you keep going add somethink that would act as a placeholder to your winform can be TableLayoutPanel

and then just add controls to it

   for ( int i = 0; i < COUNT; i++ ) {


    Label lblTitle = new Label();
    lblTitle.Text = i+"Your Text";
    youlayOut.Controls.Add( lblTitle, 0, i );

    TextBox txtValue = new TextBox();
    youlayOut.Controls.Add( txtValue, 2, i );
}

In your controller:

$scope.num_str = parseInt(num_str, 10);  // parseInt with radix

1. Create .env.development, .env.production files if not exists and add there your API endpoint, for example: VUE_APP_API_ENDPOINT ='http://localtest.me:8000'
2. In main.js file, add this line after imports: axios.defaults.baseURL = process.env.VUE_APP_API_ENDPOINT

And that's it. Axios default base Url is replaced with build mode specific API endpoint. If you need specific baseURL for specific request, do it like this:

this.$axios({ url: 'items', baseURL: 'http://new-url.com' })

If you are given this format it takes like a link to another page or another link.partial view majorly used for renduring the html files from one place to another.

            }
        }

For me non of the answers worked I saw here worked. I guessed that having the CPU work extremely hard makes the computer hot. After I closed programs that consume large amounts of CPU (like chrome) and cooling down my laptop the problem disappeared.

For reference: I had the CPU on 96%-97% and Memory usage over 2,000,000K by a java.exe process (which was actually gradle related process).

Looks like it varies depending on what compiler you're using (blech):

• gnu says %zu (or %zx, or %zd but that displays it as though it were signed, etc.)
• Microsoft says %Iu (or %Ix, or %Id but again that's signed, etc.) — but as of cl v19 (in Visual Studio 2015), Microsoft supports %zu (see this reply to this comment)

...and of course, if you're using C++, you can use cout instead as suggested by AraK.

If you don't have repeated values, you could use set difference.

x = set(range(10))
y = x - set([2, 3, 7])
# y = set([0, 1, 4, 5, 6, 8, 9])

and then convert back to list, if needed.

public static boolean CheckIsDataAlreadyInDBorNot(String TableName,
        String dbfield, String fieldValue) {
    SQLiteDatabase sqldb = EGLifeStyleApplication.sqLiteDatabase;
    String Query = "Select * from " + TableName + " where " + dbfield + " = " + fieldValue;
    Cursor cursor = sqldb.rawQuery(Query, null);
        if(cursor.getCount() <= 0){
            cursor.close();
            return false;
        }
    cursor.close();
    return true;
}

I hope this is useful to you... This function returns true if record already exists in db. Otherwise returns false.

For strings list from 1(or whatever > 0) until end.

itens = ['car', 'house', 'moon', 'sun']

v = 0
for item in itens:
    b = itens[1 + v]
    print(b)
    print('any other command')
    if b == itens[-1]:
        print('End')
        break
    v += 1

Lets Experiment with below code Playground.I Hope will clear idea what is optional and reason of using it.

var sampleString: String? ///Optional, Possible to be nil

sampleString = nil ////perfactly valid as its optional

sampleString = "some value"  //Will hold the value

if let value = sampleString{ /// the sampleString is placed into value with auto force upwraped.

    print(value+value)  ////Sample String merged into Two
}

sampleString = nil // value is nil and the

if let value = sampleString{

    print(value + value)  ///Will Not execute and safe for nil checking
}

//   print(sampleString! + sampleString!)  //this line Will crash as + operator can not add nil

Git

This answer includes GitHub as many folks have asked about that too.

Local repositories

Git (locally) has a directory (.git) which you commit your files to and this is your 'local repository'. This is different from systems like SVN where you add and commit to the remote repository immediately.

Git stores each version of a file that changes by saving the entire file. It is also different from SVN in this respect as you could go to any individual version without 'recreating' it through delta changes.

Git doesn't 'lock' files at all and thus avoids the 'exclusive lock' functionality for an edit (older systems like pvcs come to mind), so all files can always be edited, even when off-line. It actually does an amazing job of merging file changes (within the same file!) together during pulls or fetches/pushes to a remote repository such as GitHub. The only time you need to do manual changes (actually editing a file) is if two changes involve the same line(s) of code.

Branches

Branches allow you to preserve the main code (the 'master' branch), make a copy (a new branch) and then work within that new branch. If the work takes a while or master gets a lot of updates since the branch was made then merging or rebasing (often preferred for better history and easier to resolve conflicts) against the master branch should be done. When you've finished, you merge the changes made in the branch back in to the master repository. Many organizations use branches for each piece of work whether it is a feature, bug or chore item. Other organizations only use branches for major changes such as version upgrades.

Fork: With a branch you control and manage the branch, whereas with a fork someone else controls accepting the code back in.

Broadly speaking, there are two main approaches to doing branches. The first is to keep most changes on the master branch, only using branches for larger and longer-running things like version changes where you want to have two branches available for different needs. The second is whereby you basically make a branch for every feature request, bug fix or chore and then manually decide when to actually merge those branches into the main master branch. Though this sounds tedious, this is a common approach and is the one that I currently use and recommend because this keeps the master branch cleaner and it's the master that we promote to production, so we only want completed, tested code, via the rebasing and merging of branches.

The standard way to bring a branch 'in' to master is to do a merge. Branches can also be "rebased" to 'clean up' history. It doesn't affect the current state and is done to give a 'cleaner' history.

Basically, the idea is that you branched from a certain point (usually from master). Since you branched, 'master' itself has since moved forward from that branching point. It will be 'cleaner' (easier to resolve issues and the history will be easier to understand) if all the changes you have done in a branch are played against the current state of master with all of its latest changes. So, the process is: save the changes; get the 'new' master, and then reapply (this is the rebase part) the changes again against that. Be aware that rebase, just like merge, can result in conflicts that you have to manually resolve (i.e. edit and fix).

One guideline to note:
Only rebase if the branch is local and you haven't pushed it to remote yet!
This is mainly because rebasing can alter the history that other people see which may include their own commits.

Tracking branches

These are the branches that are named origin/branch_name (as opposed to just branch_name). When you are pushing and pulling the code to/from remote repositories this is actually the mechanism through which that happens. For example, when you git push a branch called building_groups, your branch goes first to origin/building_groups and then that goes to the remote repository. Similarly, if you do a git fetch building_groups, the file that is retrieved is placed in your origin/building_groups branch. You can then choose to merge this branch into your local copy. Our practice is to always do a git fetch and a manual merge rather than just a git pull (which does both of the above in one step).

Fetching new branches.

Getting new branches: At the initial point of a clone you will have all the branches. However, if other developers add branches and push them to the remote there needs to be a way to 'know' about those branches and their names in order to be able to pull them down locally. This is done via a git fetch which will get all new and changed branches into the locally repository using the tracking branches (e.g., origin/). Once fetched, one can git branch --remote to list the tracking branches and git checkout [branch] to actually switch to any given one.

Merging

Merging is the process of combining code changes from different branches, or from different versions of the same branch (for example when a local branch and remote are out of sync). If one has developed work in a branch and the work is complete, ready and tested, then it can be merged into the master branch. This is done by git checkout master to switch to the master branch, then git merge your_branch. The merge will bring all the different files and even different changes to the same files together. This means that it will actually change the code inside files to merge all the changes.

When doing the checkout of master it's also recommended to do a git pull origin master to get the very latest version of the remote master merged into your local master. If the remote master changed, i.e., moved forward, you will see information that reflects that during that git pull. If that is the case (master changed) you are advised to git checkout your_branch and then rebase it to master so that your changes actually get 'replayed' on top of the 'new' master. Then you would continue with getting master up-to-date as shown in the next paragraph.

If there are no conflicts, then master will have the new changes added in. If there are conflicts, this means that the same files have changes around similar lines of code that it cannot automatically merge. In this case git merge new_branch will report that there's conflict(s) to resolve. You 'resolve' them by editing the files (which will have both changes in them), selecting the changes you want, literally deleting the lines of the changes you don't want and then saving the file. The changes are marked with separators such as ======== and <<<<<<<<.

Once you have resolved any conflicts you will once again git add and git commit those changes to continue the merge (you'll get feedback from git during this process to guide you).

When the process doesn't work well you will find that git merge --abort is very handy to reset things.

Interactive rebasing and squashing / reordering / removing commits

If you have done work in a lot of small steps, e.g., you commit code as 'work-in-progress' every day, you may want to 'squash' those many small commits into a few larger commits. This can be particularly useful when you want to do code reviews with colleagues. You don't want to replay all the 'steps' you took (via commits), you want to just say here is the end effect (diff) of all of my changes for this work in one commit.

The key factor to evaluate when considering whether to do this is whether the multiple commits are against the same file or files more than once (better to squash commits in that case). This is done with the interactive rebasing tool. This tool lets you squash commits, delete commits, reword messages, etc. For example, git rebase -i HEAD~10 (note: that's a ~, not a -) brings up the following:

Be careful though and use this tool 'gingerly'. Do one squash/delete/reorder at a time, exit and save that commit, then reenter the tool. If commits are not contiguous you can reorder them (and then squash as needed). You can actually delete commits here too, but you really need to be sure of what you are doing when you do that!

Forks

There are two main approaches to collaboration in Git repositories. The first, detailed above, is directly via branches that people pull and push from/to. These collaborators have their SSH keys registered with the remote repository. This will let them push directly to that repository. The downside is that you have to maintain the list of users. The other approach - forking - allows anybody to 'fork' the repository, basically making a local copy in their own Git repository account. They can then make changes and when finished send a 'pull request' (really it's more of a 'push' from them and a 'pull' request for the actual repository maintainer) to get the code accepted.

This second method, using forks, does not require someone to maintain a list of users for the repository.

GitHub

GitHub (a remote repository) is a remote source that you normally push and pull those committed changes to if you have (or are added to) such a repository, so local and remote are actually quite distinct. Another way to think of a remote repository is that it is a .git directory structure that lives on a remote server.

When you 'fork' - in the GitHub web browser GUI you can click on this button - you create a copy ('clone') of the code in your GitHub account. It can be a little subtle first time you do it, so keep making sure you look at whose repository a code base is listed under - either the original owner or 'forked from' and you, e.g., like this:

Once you have the local copy, you can make changes as you wish (by pulling and pushing them to a local machine). When you are done then you submit a 'pull request' to the original repository owner/admin (sounds fancy but actually you just click on this: ) and they 'pull' it in.

More common for a team working on code together is to 'clone' the repository (click on the 'copy' icon on the repository's main screen). Then, locally type git clone and paste. This will set you up locally and you can also push and pull to the (shared) GitHub location.

Clones

As indicated in the section on GitHub, a clone is a copy of a repository. When you have a remote repository you issue the git clone command against its URL and you then end up with a local copy, or clone, of the repository. This clone has everything, the files, the master branch, the other branches, all the existing commits, the whole shebang. It is this clone that you do your adds and commits against and then the remote repository itself is what you push those commits to. It's this local/remote concept that makes Git (and systems similar to it such as Mercurial) a DVCS (Distributed Version Control System) as opposed to the more traditional CVSs (Code Versioning Systems) such as SVN, PVCS, CVS, etc. where you commit directly to the remote repository.

Visualization

Visualization of the core concepts can be seen at
http://marklodato.github.com/visual-git-guide/index-en.html and
http://ndpsoftware.com/git-cheatsheet.html#loc=index

If you want a visual display of how the changes are working, you can't beat the visual tool gitg (gitx for macOS) with a GUI that I call 'the subway map' (esp. London Underground), great for showing who did what, how things changes, diverged and merged, etc.

You can also use it to add, commit and manage your changes!

Although gitg/gitx is fairly minimal, the number of GUI tools continues to expand. Many Mac users use brotherbard's fork of gitx and for Linux, a great option is smart-git with an intuitive yet powerful interface:

Note that even with a GUI tool, you will probably do a lot of commands at the command line.

For this, I have the following aliases in my ~/.bash_aliases file (which is called from my ~/.bashrc file for each terminal session):

# git
alias g='git status'
alias gcob='git checkout -b '
alias gcom='git checkout master'
alias gd='git diff'
alias gf='git fetch'
alias gfrm='git fetch; git reset --hard origin/master'
alias gg='git grep '
alias gits='alias | grep "^alias g.*git.*$"'
alias gl='git log'
alias gl1='git log --oneline'
alias glf='git log --name-status'
alias glp='git log -p'
alias gpull='git pull '
alias gpush='git push '

AND I have the following "git aliases" in my ~/.gitconfig file - why have these ?
So that branch completion (with the TAB key) works !

So these are:

[alias]
  co = checkout
  cob = checkout -b

Example usage: git co [branch] <- tab completion for branches will work.

Finally, 7 key lifesavers!

1. You make changes, add and commit them (but don't push) and then oh! you realize you are in master!

   git reset [filename(s)]
   git checkout -b [name_for_a_new_branch]
   git add [file(s)]
   git commit -m "A useful message"
   
   Voila!  You've moved that 'master' commit to its own branch !
   

2. You mess up some files while working in a local branch and simply want to go back to what you had the last time you did a git pull:

   git reset --hard origin/master  # You will need to be comfortable doing this!
   

3. You start making changes locally, you edit half a dozen files and then, oh crap, you're still in the master (or another) branch:

   git checkout -b new_branch_name  # just create a new branch
   git add .                      # add the changes files
   git commit -m"your message"    # and commit them
   

4. You mess up one particular file in your current branch and want to basically 'reset' that file (lose changes) to how it was the the last time you pulled it from the remote repository:

   git checkout your/directories/filename
   

   This actually resets the file (like many Git commands it is not well named for what it is doing here).

5. You make some changes locally, you want to make sure you don't lose them while you do a git reset or rebase: I often make a manual copy of the entire project (cp -r ../my_project ~/) when I am not sure if I might mess up in Git or lose important changes.

6. You are rebasing but things gets messed up:

   git rebase --abort # To abandon interactive rebase and merge issues
   

7. Add your Git branch to your PS1 prompt (see https://unix.stackexchange.com/a/127800/10043), e.g.

   

   The branch is selenium_rspec_conversion.

In Visual Studio 2017 Spanish version.

"Depurar" -> "Ventanas" -> "Configuración de Excepciones"

and search "ContextSwitchDeadlock". Then, uncheck it. Or shortcut

Ctrl+D,E

Best.

While creating chrome driver, use option to disable it. Its working without any extensions.

Use following code snippet

ChromeOptions options = new ChromeOptions();
options.addArguments("chrome.switches","--disable-extensions");
System.setProperty("webdriver.chrome.driver",(System.getProperty("user.dir") + "//src//test//resources//chromedriver_new.exe"));
driver = new ChromeDriver(options);

Based on this post here you can simply download the Microsoft Visual Studio 2010 Shell (Integrated) Redistributable Package and the targets are installed.

This avoids the need to install Visual Studio on the build server.

I have just tried this out now, and can verify that it works:

Before:

error MSB4019: The imported project "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk.

After the install:

[Builds correctly]

This is a far better solution than installing Visual Studio on a build server, obviously.

I had the same problem: you should only use a 9-patch image (.9.png) instead of your original picture.

Solution to this problem is simple

Go to build.gradle (module.app) file

It will help us to rebuild gradle for the project, to make it sync again.

So, that is why i do a two (or more) post.

I was having the same problem when starting the service (logs can not be opened).

I thought it was because i was trying to have htdocs inside a VeraCrypt encripted container, absurd since i hace such contained mounted and i use a juntion to not affect paths.

The i read the cause could be low ram: after some tests i get to the next conclusion.

Windows is not sending pages to virtual ram to free enough ram if it is a service, for applications it is doing it, i have more than 200GiB of pagefile ready to be used as virtual ram in a 4GiB 64 Bit windows 10.

My solution:

1. Run a free utility that free ram (512MiB in my test)
2. Inmediatly after start the service, it starts with no errors

Real Cause:

• I was using a virtual machine that uses 1/2 physical free ram (1.5GiB)

Hope this help others.

This may not be an option for you, but if you can use the Parallel Extension for .NET then you could use Tasks instead of raw threads and then use Task.WaitAll() to wait for them to complete.

Have you tried setting the selection properties of your tableView like this:

tableView.allowsMultipleSelection = NO; tableView.allowsMultipleSelectionDuringEditing = YES; tableView.allowsSelection = NO; tableView.allowsSelectionDuringEditing YES; 

If you want more fine-grain control over when selection is allowed you can override - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath in your UITableView delegate. The documentation states:

Return Value An index-path object that confirms or alters the selected row. Return an NSIndexPath object other than indexPath if you want another cell to be selected. Return nil if you don't want the row selected. 

You can have this method return nil in cases where you don't want the selection to happen.

Let's say we have a string called yourstring:

for x in range(0, [howmanytimes you want it at the beginning]):
    yourstring = "L" + yourstring
for x in range(0, [howmanytimes you want it at the end]):
    yourstring += "L"

A -exec command must be terminated with a ; (so you usually need to type \; or ';' to avoid interpretion by the shell) or a +. The difference is that with ;, the command is called once per file, with +, it is called just as few times as possible (usually once, but there is a maximum length for a command line, so it might be split up) with all filenames. See this example:

$ cat /tmp/echoargs
#!/bin/sh
echo $1 - $2 - $3
$ find /tmp/foo -exec /tmp/echoargs {} \;
/tmp/foo - -
/tmp/foo/one - -
/tmp/foo/two - -
$ find /tmp/foo -exec /tmp/echoargs {} +
/tmp/foo - /tmp/foo/one - /tmp/foo/two

Your command has two errors:

First, you use {};, but the ; must be a parameter of its own.

Second, the command ends at the &&. You specified “run find, and if that was successful, remove the file named {};.“. If you want to use shell stuff in the -exec command, you need to explicitly run it in a shell, such as -exec sh -c 'ffmpeg ... && rm'.

However you should not add the {} inside the bash command, it will produce problems when there are special characters. Instead, you can pass additional parameters to the shell after -c command_string (see man sh):

$ ls
$(echo damn.)
$ find * -exec sh -c 'echo "{}"' \;
damn.
$ find * -exec sh -c 'echo "$1"' - {} \;
$(echo damn.)

You see the $ thing is evaluated by the shell in the first example. Imagine there was a file called $(rm -rf /) :-)

(Side note: The - is not needed, but the first variable after the command is assigned to the variable $0, which is a special variable normally containing the name of the program being run and setting that to a parameter is a little unclean, though it won't cause any harm here probably, so we set that to just - and start with $1.)

So your command could be something like

find -exec bash -c 'ffmpeg -i "$1" -sameq "$1".mp3 && rm "$1".mp3' - {} \;

But there is a better way. find supports and and or, so you may do stuff like find -name foo -or -name bar. But that also works with -exec, which evaluates to true if the command exits successfully, and to false if not. See this example:

$ ls
false  true
$ find * -exec {} \; -and -print
true

It only runs the print if the command was successfully, which it did for true but not for false.

So you can use two exec statements chained with an -and, and it will only execute the latter if the former was run successfully.

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

This may mean that you are installing the wrong pre-build binary

since my CPU on Ubuntu 18.04 my download url was: https://github.com/lakshayg/tensorflow-build/releases/download/tf1.12.0-ubuntu18.04-py2-py3/tensorflow-1.12.0-cp36-cp36m-linux_x86_64.whl

as it can be found on this github page: https://github.com/lakshayg/tensorflow-build

pip install --ignore-installed --upgrade <LOCAL PATH / BINARY-URL>

resolved the issue for me.

It evaluates to the left operand if the left operand is truthy, and the right operand otherwise.

In pseudocode,

foo = bar ?: baz;

roughly resolves to

foo = bar ? bar : baz;

or

if (bar) {
    foo = bar;
} else {
    foo = baz;
}

with the difference that bar will only be evaluated once.

You can also use this to do a "self-check" of foo as demonstrated in the code example you posted:

foo = foo ?: bar;

This will assign bar to foo if foo is null or falsey, else it will leave foo unchanged.

Some more examples:

<?php
    var_dump(5 ?: 0); // 5
    var_dump(false ?: 0); // 0
    var_dump(null ?: 'foo'); // 'foo'
    var_dump(true ?: 123); // true
    var_dump('rock' ?: 'roll'); // 'rock'
?>

By the way, it's called the Elvis operator.

function pad_2(number)
{
     return (number < 10 ? '0' : '') + number;
}

function hours(date)
{
    var hours = date.getHours();
    if(hours > 12)
        return hours - 12; // Substract 12 hours when 13:00 and more
    return hours;
}

function am_pm(date)
{
    if(date.getHours()==0 && date.getMinutes()==0 && date.getSeconds()==0)
        return ''; // No AM for MidNight
    if(date.getHours()==12 && date.getMinutes()==0 && date.getSeconds()==0)
        return ''; // No PM for Noon
    if(date.getHours()<12)
        return ' AM';
    return ' PM';
}

function date_format(date)
{
     return pad_2(date.getDate()) + '/' +
            pad_2(date.getMonth()+1) + '/' +
            (date.getFullYear() + ' ').substring(2) +
            pad_2(hours(date)) + ':' +
            pad_2(date.getMinutes()) +
            am_pm(date);
}

The solution for me was that default-ssl was not enabled in apache 2.... just putting SSLEngine On

I had to execute a2ensite default-ssl and everything worked.

^{This answer is all about authorization and it is a complement of my previous answer about authentication}

^{Why another answer? I attempted to expand my previous answer by adding details on how to support JSR-250 annotations. However the original answer became the way too long and exceeded the maximum length of 30,000 characters. So I moved the whole authorization details to this answer, keeping the other answer focused on performing authentication and issuing tokens.}

Supporting role-based authorization with the @Secured annotation

Besides authentication flow shown in the other answer, role-based authorization can be supported in the REST endpoints.

Create an enumeration and define the roles according to your needs:

public enum Role {
    ROLE_1,
    ROLE_2,
    ROLE_3
}

Change the @Secured name binding annotation created before to support roles:

@NameBinding
@Retention(RUNTIME)
@Target({TYPE, METHOD})
public @interface Secured {
    Role[] value() default {};
}

And then annotate the resource classes and methods with @Secured to perform the authorization. The method annotations will override the class annotations:

@Path("/example")
@Secured({Role.ROLE_1})
public class ExampleResource {

    @GET
    @Path("{id}")
    @Produces(MediaType.APPLICATION_JSON)
    public Response myMethod(@PathParam("id") Long id) {
        // This method is not annotated with @Secured
        // But it's declared within a class annotated with @Secured({Role.ROLE_1})
        // So it only can be executed by the users who have the ROLE_1 role
        ...
    }

    @DELETE
    @Path("{id}")    
    @Produces(MediaType.APPLICATION_JSON)
    @Secured({Role.ROLE_1, Role.ROLE_2})
    public Response myOtherMethod(@PathParam("id") Long id) {
        // This method is annotated with @Secured({Role.ROLE_1, Role.ROLE_2})
        // The method annotation overrides the class annotation
        // So it only can be executed by the users who have the ROLE_1 or ROLE_2 roles
        ...
    }
}

Create a filter with the AUTHORIZATION priority, which is executed after the AUTHENTICATION priority filter defined previously.

The ResourceInfo can be used to get the resource Method and resource Class that will handle the request and then extract the @Secured annotations from them:

@Secured
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        // Get the resource class which matches with the requested URL
        // Extract the roles declared by it
        Class<?> resourceClass = resourceInfo.getResourceClass();
        List<Role> classRoles = extractRoles(resourceClass);

        // Get the resource method which matches with the requested URL
        // Extract the roles declared by it
        Method resourceMethod = resourceInfo.getResourceMethod();
        List<Role> methodRoles = extractRoles(resourceMethod);

        try {

            // Check if the user is allowed to execute the method
            // The method annotations override the class annotations
            if (methodRoles.isEmpty()) {
                checkPermissions(classRoles);
            } else {
                checkPermissions(methodRoles);
            }

        } catch (Exception e) {
            requestContext.abortWith(
                Response.status(Response.Status.FORBIDDEN).build());
        }
    }

    // Extract the roles from the annotated element
    private List<Role> extractRoles(AnnotatedElement annotatedElement) {
        if (annotatedElement == null) {
            return new ArrayList<Role>();
        } else {
            Secured secured = annotatedElement.getAnnotation(Secured.class);
            if (secured == null) {
                return new ArrayList<Role>();
            } else {
                Role[] allowedRoles = secured.value();
                return Arrays.asList(allowedRoles);
            }
        }
    }

    private void checkPermissions(List<Role> allowedRoles) throws Exception {
        // Check if the user contains one of the allowed roles
        // Throw an Exception if the user has not permission to execute the method
    }
}

If the user has no permission to execute the operation, the request is aborted with a 403 (Forbidden).

To know the user who is performing the request, see my previous answer. You can get it from the SecurityContext (which should be already set in the ContainerRequestContext) or inject it using CDI, depending on the approach you go for.

If a @Secured annotation has no roles declared, you can assume all authenticated users can access that endpoint, disregarding the roles the users have.

Supporting role-based authorization with JSR-250 annotations

Alternatively to defining the roles in the @Secured annotation as shown above, you could consider JSR-250 annotations such as @RolesAllowed, @PermitAll and @DenyAll.

JAX-RS doesn't support such annotations out-of-the-box, but it could be achieved with a filter. Here are a few considerations to keep in mind if you want to support all of them:

• @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll on the class.
• @RolesAllowed on the method takes precedence over @PermitAll on the class.
• @PermitAll on the method takes precedence over @RolesAllowed on the class.
• @DenyAll can't be attached to classes.
• @RolesAllowed on the class takes precedence over @PermitAll on the class.

So an authorization filter that checks JSR-250 annotations could be like:

@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        Method method = resourceInfo.getResourceMethod();

        // @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll
        if (method.isAnnotationPresent(DenyAll.class)) {
            refuseRequest();
        }

        // @RolesAllowed on the method takes precedence over @PermitAll
        RolesAllowed rolesAllowed = method.getAnnotation(RolesAllowed.class);
        if (rolesAllowed != null) {
            performAuthorization(rolesAllowed.value(), requestContext);
            return;
        }

        // @PermitAll on the method takes precedence over @RolesAllowed on the class
        if (method.isAnnotationPresent(PermitAll.class)) {
            // Do nothing
            return;
        }

        // @DenyAll can't be attached to classes

        // @RolesAllowed on the class takes precedence over @PermitAll on the class
        rolesAllowed = 
            resourceInfo.getResourceClass().getAnnotation(RolesAllowed.class);
        if (rolesAllowed != null) {
            performAuthorization(rolesAllowed.value(), requestContext);
        }

        // @PermitAll on the class
        if (resourceInfo.getResourceClass().isAnnotationPresent(PermitAll.class)) {
            // Do nothing
            return;
        }

        // Authentication is required for non-annotated methods
        if (!isAuthenticated(requestContext)) {
            refuseRequest();
        }
    }

    /**
     * Perform authorization based on roles.
     *
     * @param rolesAllowed
     * @param requestContext
     */
    private void performAuthorization(String[] rolesAllowed, 
                                      ContainerRequestContext requestContext) {

        if (rolesAllowed.length > 0 && !isAuthenticated(requestContext)) {
            refuseRequest();
        }

        for (final String role : rolesAllowed) {
            if (requestContext.getSecurityContext().isUserInRole(role)) {
                return;
            }
        }

        refuseRequest();
    }

    /**
     * Check if the user is authenticated.
     *
     * @param requestContext
     * @return
     */
    private boolean isAuthenticated(final ContainerRequestContext requestContext) {
        // Return true if the user is authenticated or false otherwise
        // An implementation could be like:
        // return requestContext.getSecurityContext().getUserPrincipal() != null;
    }

    /**

    private void refuseRequest() {
        throw new AccessDeniedException(
            "You don't have permissions to perform this action.");
    }
}

^{Note: The above implementation is based on the Jersey RolesAllowedDynamicFeature. If you use Jersey, you don't need to write your own filter, just use the existing implementation.}

It depends on what you are trying to do.

file, err := os.Open("file.txt")
fmt.print(file)

The reason it outputs &{0xc082016240}, is because you are printing the pointer value of a file-descriptor (*os.File), not file-content. To obtain file-content, you may READ from a file-descriptor.

To read all file content(in bytes) to memory, ioutil.ReadAll

package main

import (
    "fmt"
    "io/ioutil"
    "os"
    "log"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


  b, err := ioutil.ReadAll(file)
  fmt.Print(b)
}

But sometimes, if the file size is big, it might be more memory-efficient to just read in chunks: buffer-size, hence you could use the implementation of io.Reader.Read from *os.File

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


    buf := make([]byte, 32*1024) // define your buffer size here.

    for {
        n, err := file.Read(buf)

        if n > 0 {
            fmt.Print(buf[:n]) // your read buffer.
        }

        if err == io.EOF {
            break
        }
        if err != nil {
            log.Printf("read %d bytes: %v", n, err)
            break
        }
    }

}

Otherwise, you could also use the standard util package: bufio, try Scanner. A Scanner reads your file in tokens: separator.

By default, scanner advances the token by newline (of course you can customise how scanner should tokenise your file, learn from here the bufio test).

package main

import (
    "fmt"
    "os"
    "log"
    "bufio"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()

    scanner := bufio.NewScanner(file)

    for scanner.Scan() {             // internally, it advances token based on sperator
        fmt.Println(scanner.Text())  // token in unicode-char
        fmt.Println(scanner.Bytes()) // token in bytes

    }
}

Lastly, I would also like to reference you to this awesome site: go-lang file cheatsheet. It encompassed pretty much everything related to working with files in go-lang, hope you'll find it useful.

I think floats may work best for you here, if you dont want the element to occupy the whole line, float it left should work.

.text span {
       background:rgba(165, 220, 79, 0.8);
       float: left;
       clear: left;
       padding:7px 10px;
       color:white;
    }

Note:Remove <br/>'s before using this off course.

This does not work in Chrome Developer tools to locate a element, i am looking to locate the 'Submit' button in the screen

//input[matches(@value,'submit','i')]

However, using 'translate' to replace all caps to small works as below

//input[translate(@value,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz') = 'submit']

Update: I just found the reason why 'matches' doesnt work. I am using Chrome with xpath 1.0 which wont understand the syntax 'matches'. It should be xpath 2.0

In Chrome, For "Selenium IDE", I was also struggling that it doesn't pause. It will pause, if you give as below:

• Command: pause
• Target: blank
• Value: 10000

This will pause for 10 seconds.

Summary:

Use is when you want to check against an object's identity (e.g. checking to see if var is None). Use == when you want to check equality (e.g. Is var equal to 3?).

Explanation:

You can have custom classes where my_var == None will return True

e.g:

class Negator(object):
    def __eq__(self,other):
        return not other

thing = Negator()
print thing == None    #True
print thing is None    #False

is checks for object identity. There is only 1 object None, so when you do my_var is None, you're checking whether they actually are the same object (not just equivalent objects)

In other words, == is a check for equivalence (which is defined from object to object) whereas is checks for object identity:

lst = [1,2,3]
lst == lst[:]  # This is True since the lists are "equivalent"
lst is lst[:]  # This is False since they're actually different objects

Similar to npocmaka's solution, if you are having more than one line of batch code in your batch file besides the python code, check this out: http://lallouslab.net/2017/06/12/batchography-embedding-python-scripts-in-your-batch-file-script/

@echo off
rem = """
echo some batch commands
echo another batch command
python -x "%~f0" %*
echo some more batch commands
goto :eof

"""
# Anything here is interpreted by Python
import platform
import sys
print("Hello world from Python %s!\n" % platform.python_version())
print("The passed arguments are: %s" % sys.argv[1:])

What this code does is it runs itself as a python file by putting all the batch code into a multiline string. The beginning of this string is in a variable called rem, to make the batch code read it as a comment. The first line containing @echo off is ignored in the python code because of the -x parameter.

it is important to mention that if you want to use \ in your batch code, for example in a file path, you'll have to use r"""...""" to surround it to use it as a raw string without escape sequences.

@echo off
rem = r"""
...
"""

Try this

@Override
public boolean onCreateOptionsMenu(Menu menu){
    MenuInflater inflater = getMenuInflater();

I have a different take on this. I could do a docker ps and see that there is a docker container running, I even tried to restart it, but as soon as I tried to get a session for it with New-PSSession -ContainerId $containerId -RunAsAdministrator It would error out, saying:

##[error]New-PSSession : The input ContainerId xxx does not exist, ##[error]or the corresponding container is not running.

My problem was I was running with network service and it did not have enough permissions to see the container, even though I had given it permissions to run docker commands (with docker security group configuration)

I didn't know how to enable working with containers, so I had to revert to running it as an admin user instead

The best way to check for named elements is to use exist(), however the above answers are not using the function properly. You need to use the where argument to check for the variable within the list.

foo <- list(a=42, b=NULL)

exists('a', where=foo) #TRUE
exists('b', where=foo) #TRUE
exists('c', where=foo) #FALSE

nltk is convenient for a lot of language processing stuff. It has methods for frequency distribution built in. Something like:

import nltk
fdist = nltk.FreqDist(your_list) # creates a frequency distribution from a list
most_common = fdist.max()    # returns a single element
top_three = fdist.keys()[:3] # returns a list

This is by far the coolest thing I've seen... and when broken down, it's actually pretty simple:

http://blogs.msdn.com/lukeh/archive/2007/04/03/a-ray-tracer-in-c-3-0.aspx

From the documentation of XPath ( http://www.w3.org/TR/xpath/#location-paths ):

child::* selects all element children of the context node

child::text() selects all text node children of the context node

child::node() selects all the children of the context node, whatever their node type

So I guess your answer is:

$doc/PRESENTEDIN/X/child::node()

And if you want a flatten array of all nested nodes:

$doc/PRESENTEDIN/X/descendant::node()

Try this code:

<?php
    header("Content-type: application/vnd-ms-excel");

    header("Content-Disposition: attachment; filename=hasil-export.xls");

    include 'view-lap.php';
?>

Try to check outline on button's focus:

button:focus {
    outline: blue auto 5px; 
}

If you have it, just set it to none.

If all above answers is not to your liking you can use autoIT to run your file (or what ever file) as a specific user with their credentials.

Sample of a script that will run a program using that users privelages.

installAdmin()

Func installAdmin()
    ; Change the username and password to the appropriate values for your system.
    Local $sUserName = "xxxxx"
    Local $sPassword = "xxx"
    Local $sDirectory = "C:\ASD4VM\Download\"
    Local $sFiletoRun = "Inst_with_Privileges.bat"

    RunAsWait($sUserName, @ComputerName, $sPassword, 0, $sDirectory & $sFiletoRun)
EndFunc   ;==>Example

AutoIT can be found here. -> It uses a .ua3 format that is compiled to a .exe file that can be run.

I was also looking for the relative path version, this works OK. Note when run (Spyder 3.6) you will see (unicode error) 'unicodeescape' codec can't decode bytes at the closing triple quote. Remove the offending comment lines 14 and 15 and adjust the file names and location for your environment and check for indentation.

You have to use the NotifyIcon control from System.Windows.Forms, or alternatively you can use the Notify Icon API provided by Windows API. WPF Provides no such equivalent, and it has been requested on Microsoft Connect several times.

I have code on GitHub which uses System.Windows.Forms NotifyIcon Component from within a WPF application, the code can be viewed at https://github.com/wilson0x4d/Mubox/blob/master/Mubox.QuickLaunch/AppWindow.xaml.cs

Here are the summary bits:

Create a WPF Window with ShowInTaskbar=False, and which is loaded in a non-Visible State.

At class-level:

private System.Windows.Forms.NotifyIcon notifyIcon = null;

During OnInitialize():

notifyIcon = new System.Windows.Forms.NotifyIcon();
notifyIcon.Click += new EventHandler(notifyIcon_Click);
notifyIcon.DoubleClick += new EventHandler(notifyIcon_DoubleClick);
notifyIcon.Icon = IconHandles["QuickLaunch"];

During OnLoaded():

notifyIcon.Visible = true;

And for interaction (shown as notifyIcon.Click and DoubleClick above):

void notifyIcon_Click(object sender, EventArgs e)
{
    ShowQuickLaunchMenu();
}

From here you can resume the use of WPF Controls and APIs such as context menus, pop-up windows, etc.

It's that simple. You don't exactly need a WPF Window to host to the component, it's just the most convenient way to introduce one into a WPF App (as a Window is generally the default entry point defined via App.xaml), likewise, you don't need a WPF Wrapper or 3rd party control, as the SWF component is guaranteed present in any .NET Framework installation which also has WPF support since it's part of the .NET Framework (which all current and future .NET Framework versions build upon.) To date, there is no indication from Microsoft that SWF support will be dropped from the .NET Framework anytime soon.

Hope that helps.

It's a little cheese that you have to use a pre-3.0 Framework Component to get a tray-icon, but understandably as Microsoft has explained it, there is no concept of a System Tray within the scope of WPF. WPF is a presentation technology, and Notification Icons are an Operating System (not a "Presentation") concept.

Yes, most notably! I don't think the second one will work (and if it does, not very portably). The first one should be OK.

// HTML:
<input id="theId" value="test" onclick="doSomething(this)" />

// JavaScript:
function(elem){
    var value = elem.value;
    var id    = elem.id;
    ...
}

This should also work.

Update: the question was edited. Both of the solutions are now equivalent.

Here is example of pseudo-random generator when neither $RANDOM nor /dev/urandom is available

Try /me/taggable_friends?limit=5000 using your JavaScript code

Or

try the Graph API:

The vector you are creating is neither row nor column. It actually has 1 dimension only. You can verify that by

• checking the number of dimensions myvector.ndim which is 1
• checking the myvector.shape, which is (3,) (a tuple with one element only). For a row vector is should be (1, 3), and for a column (3, 1)

Two ways to handle this

• create an actual row or column vector
• reshape your current one

You can explicitly create a row or column

row = np.array([    # one row with 3 elements
   [1, 2, 3]
]
column = np.array([  # 3 rows, with 1 element each
    [1],
    [2],
    [3]
])

or, with a shortcut

row = np.r_['r', [1,2,3]]     # shape: (1, 3)
column = np.r_['c', [1,2,3]]  # shape: (3,1)

Alternatively, you can reshape it to (1, n) for row, or (n, 1) for column

row = my_vector.reshape(1, -1)
column = my_vector.reshape(-1, 1)

where the -1 automatically finds the value of n.

You just have to partition the problem into some bite-sized steps and solve each one by one

First, get the maximum score in each subject:

select SubjectID, max(MarkRate)
from Mark
group by SubjectID;

Then query who are those that has SubjectID with max MarkRate:

select SubjectID, MarkRate, StudentID
from Mark
where (SubjectID,MarkRate)
in
  (
  select SubjectID, max(MarkRate)
  from Mark
  group by SubjectID
  )
order by SubjectID, StudentID;

Then obtain the Student's name, instead of displaying just the StudentID:

select SubjectName, MarkRate, StudentName
from Mark
join Student using(StudentID)
join Subject using(SubjectID)
where (SubjectID,MarkRate)
in
  (
  select SubjectID, max(MarkRate)
  from Mark
  group by SubjectID
  )
order by SubjectName, StudentName

Database vendors' artificial differences aside with regards to joining and correlating results, the basic step is the same; first, partition the problem in a bite-sized parts, and then integrate them as you solved each one of them, so it won't be as confusing.

Sample data:

CREATE TABLE Student
    (StudentID int, StudentName varchar(6), Details varchar(1));    
INSERT INTO Student
    (StudentID, StudentName, Details)
VALUES
    (1, 'John', 'X'),
    (2, 'Paul', 'X'),
    (3, 'George', 'X'),
    (4, 'Paul', 'X');

CREATE TABLE Subject
    (SubjectID varchar(1), SubjectName varchar(7));    
INSERT INTO Subject
    (SubjectID, SubjectName)
VALUES
    ('M', 'Math'),
    ('E', 'English'),
    ('H', 'History');

CREATE TABLE Mark
    (StudentID int, SubjectID varchar(1), MarkRate int);    
INSERT INTO Mark
    (StudentID, SubjectID, MarkRate)
VALUES
    (1, 'M', 90),
    (1, 'E', 100),
    (2, 'M', 95),
    (2, 'E', 70),
    (3, 'E', 95),
    (3, 'H', 98),
    (4, 'H', 90),
    (4, 'E', 100);

Live test here: http://www.sqlfiddle.com/#!1/08728/3

IN tuple test is still a join by any other name:

Convert this..

select SubjectName, MarkRate, StudentName
from Mark
join Student using(StudentID)
join Subject using(SubjectID)

where (SubjectID,MarkRate)
in
  (
  select SubjectID, max(MarkRate)
  from Mark
  group by SubjectID
  )

order by SubjectName, StudentName

..to JOIN:

select SubjectName, MarkRate, StudentName
from Mark
join Student using(StudentID)
join Subject using(SubjectID)

join
  (
  select SubjectID, max(MarkRate) as MarkRate
  from Mark
  group by SubjectID
  ) as x using(SubjectID,MarkRate)

order by SubjectName, StudentName

Contrast this code with the code immediate it. See how JOIN on independent query look like an IN construct? They almost look the same, and IN was just replaced with JOIN keyword; and the replaced IN keyword with JOIN is in fact longer, you need to alias the independent query's column result(max(MarkRate) AS MarkRate) and also the subquery itself (as x). Anyway, this are just matter of style, I prefer IN clause, as the intent is clearer. Using JOINs merely to reflect the data relationship.

Anyway, here's the query that works on all databases that doesn't support tuple test(IN):

select sb.SubjectName, m.MarkRate, st.StudentName
from Mark as m
join Student as st on st.StudentID = m.StudentID
join Subject as sb on sb.SubjectID = m.SubjectID

join
  (
  select SubjectID, max(MarkRate) as MaxMarkRate
  from Mark
  group by SubjectID
  ) as x on m.SubjectID = x.SubjectID AND m.MarkRate = x.MaxMarkRate

order by sb.SubjectName, st.StudentName

Same issue on Fedora 23. I had to reinstall python3-pip to generate the proper pip3 folders in /usr/bin/.

sudo dnf reinstall python3-pip

DateTime.Now returns a DateTime value that consists of the local date and time of the computer where the code is running. It has DateTimeKind.Local assigned to its Kind property. It is equivalent to calling any of the following:

• DateTime.UtcNow.ToLocalTime()
• DateTimeOffset.UtcNow.LocalDateTime
• DateTimeOffset.Now.LocalDateTime
• TimeZoneInfo.ConvertTime(DateTime.UtcNow, TimeZoneInfo.Local)
• TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, TimeZoneInfo.Local)

DateTime.Today returns a DateTime value that has the same year, month, and day components as any of the above expressions, but with the time components set to zero. It also has DateTimeKind.Local in its Kind property. It is equivalent to any of the following:

• DateTime.Now.Date
• DateTime.UtcNow.ToLocalTime().Date
• DateTimeOffset.UtcNow.LocalDateTime.Date
• DateTimeOffset.Now.LocalDateTime.Date
• TimeZoneInfo.ConvertTime(DateTime.UtcNow, TimeZoneInfo.Local).Date
• TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, TimeZoneInfo.Local).Date

Note that internally, the system clock is in terms of UTC, so when you call DateTime.Now it first gets the UTC time (via the GetSystemTimeAsFileTime function in the Win32 API) and then it converts the value to the local time zone. (Therefore DateTime.Now.ToUniversalTime() is more expensive than DateTime.UtcNow.)

Also note that DateTimeOffset.Now.DateTime will have similar values to DateTime.Now, but it will have DateTimeKind.Unspecified rather than DateTimeKind.Local - which could lead to other errors depending on what you do with it.

So, the simple answer is that DateTime.Today is equivalent to DateTime.Now.Date.
But IMHO - You shouldn't use either one of these, or any of the above equivalents.

When you ask for DateTime.Now, you are asking for the value of the local calendar clock of the computer that the code is running on. But what you get back does not have any information about that clock! The best that you get is that DateTime.Now.Kind == DateTimeKind.Local. But whose local is it? That information gets lost as soon as you do anything with the value, such as store it in a database, display it on screen, or transmit it using a web service.

If your local time zone follows any daylight savings rules, you do not get that information back from DateTime.Now. In ambiguous times, such as during a "fall-back" transition, you won't know which of the two possible moments correspond to the value you retrieved with DateTime.Now. For example, say your system time zone is set to Mountain Time (US & Canada) and you ask for DateTime.Now in the early hours of November 3rd, 2013. What does the result 2013-11-03 01:00:00 mean? There are two moments of instantaneous time represented by this same calendar datetime. If I were to send this value to someone else, they would have no idea which one I meant. Especially if they are in a time zone where the rules are different.

The best thing you could do would be to use DateTimeOffset instead:

// This will always be unambiguous.
DateTimeOffset now = DateTimeOffset.Now;

Now for the same scenario I described above, I get the value 2013-11-03 01:00:00 -0600 before the transition, or 2013-11-03 01:00:00 -0700 after the transition. Anyone looking at these values can tell what I meant.

I wrote a blog post on this very subject. Please read - The Case Against DateTime.Now.

Also, there are some places in this world (such as Brazil) where the "spring-forward" transition happens exactly at Midnight. The clocks go from 23:59 to 01:00. This means that the value you get for DateTime.Today on that date, does not exist! Even if you use DateTimeOffset.Now.Date, you are getting the same result, and you still have this problem. It is because traditionally, there has been no such thing as a Date object in .Net. So regardless of how you obtain the value, once you strip off the time - you have to remember that it doesn't really represent "midnight", even though that's the value you're working with.

If you really want a fully correct solution to this problem, the best approach is to use NodaTime. The LocalDate class properly represents a date without a time. You can get the current date for any time zone, including the local system time zone:

using NodaTime;
...

Instant now = SystemClock.Instance.Now;

DateTimeZone zone1 = DateTimeZoneProviders.Tzdb.GetSystemDefault();
LocalDate todayInTheSystemZone = now.InZone(zone1).Date;

DateTimeZone zone2 = DateTimeZoneProviders.Tzdb["America/New_York"];
LocalDate todayInTheOtherZone = now.InZone(zone2).Date;

If you don't want to use Noda Time, there is now another option. I've contributed an implementation of a date-only object to the .Net CoreFX Lab project. You can find the System.Time package object in their MyGet feed. Once added to your project, you will find you can do any of the following:

using System;
...

Date localDate = Date.Today;

Date utcDate = Date.UtcToday;

Date tzSpecificDate = Date.TodayInTimeZone(anyTimeZoneInfoObject);

There is no portable way to get resolution of less than a second in standard C So best you can do is, use the POSIX function gettimeofday().

Google has just released a cross-platform open source tool for inspecting APKs (among many other binary Android formats):

ClassyShark is a standalone binary inspection tool for Android developers. It can reliably browse any Android executable and show important info such as class interfaces and members, dex counts and dependencies. ClassyShark supports multiple formats including libraries (.dex, .aar, .so), executables (.apk, .jar, .class) and all Android binary XMLs: AndroidManifest, resources, layouts etc.

From the documentation:

/is Includes the same files. /it Includes "tweaked" files.

"Same files" means files that are identical (name, size, times, attributes). "Tweaked files" means files that have the same name, size, and times, but different attributes.

robocopy src dst sample.txt /is      # copy if attributes are equal
robocopy src dst sample.txt /it      # copy if attributes differ
robocopy src dst sample.txt /is /it  # copy irrespective of attributes

This answer on Super User has a good explanation of what kind of files the selection parameters match.

With that said, I could reproduce the behavior you describe, but from my understanding of the documentation and the output robocopy generated in my tests I would consider this a bug.

The file is listed as copied, and since it becomes a same file after the first robocopy run at least the times are synced. However, even though seven bytes have been copied according to the output no data was actually written to the destination file in both cases despite the data flag being set (via /copyall). The behavior also doesn't change if the data flag is set explicitly (/copy:d).

I had to modify the last write time to get robocopy to actually synchronize the data.

An admittedly ugly workaround would be to change the last write time of same/tweaked files to force robocopy to copy the data:

& robocopy src dst /is /it /l /ndl /njh /njs /ns /nc |
  Where-Object { $_.Trim() } |
  ForEach-Object {
    $f = Get-Item $_
    $f.LastWriteTime = $f.LastWriteTime.AddSeconds(1)
  }
& robocopy src dst /copyall /mir

Switching to xcopy is probably your best option:

& xcopy src dst /k/r/e/i/s/c/h/f/o/x/y

You can use the Ext.util.Format.ellipsis function if you are using Ext.js.

In your Jenkins job configuration, tick the box named "This build is parameterized", click the "Add Parameter" button and select the "String Parameter" drop down value.

Now define your parameter - example:

Now you can use your parameter in your job / build pipeline, example:

Next to trigger the build with own/custom parameter, invoke the following URL (using either POST or GET):

http://JENKINS_SERVER_ADDRESS/job/YOUR_JOB_NAME/buildWithParameters?myparam=myparam_value

The above answers are good. I want to add another point. Up to some values both of them result in the same quotient. After that floor division operator (//) works fine but not division (/) operator.

 - > int(755349677599789174/2)
 - > 377674838799894592      #wrong answer
 - > 755349677599789174 //2
 - > 377674838799894587      #correct answer

The bottom statement is equivalent to:

.half {
   flex-grow: 0;
   flex-shrink: 0;
   flex-basis: 50%;
}

Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.

Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.

I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)

EDIT: It appears that this method is not supported anymore (thx to @FernandoZamperin). Please take a look at the other answers!

Instead of subscribing to a topic you could instead make use of the condition key and send messages to instances, that are not in a group. Your data might look something like this:

{
    "data": {
        "foo": "bar"
    },
    "condition": "!('anytopicyoudontwanttouse' in topics)"
}

See https://firebase.google.com/docs/cloud-messaging/send-message#send_messages_to_topics_2

            break;

    return a;
}

You can analyze the core dump file using the "gdb" command.

Your question is vague but you could use ShowDialog to display form 2. Then when you close form 2, pass a DialogResult object back to let the user know how the form was closed - if the user clicked the button, then close form 1 as well.

Here is a query to find all product sales that were running during the month of August

• Find Product_sales there were active during the month of August
• Include anything that started before the end of August
• Exclude anything that ended before August 1st

Also adds a case statement to validate the query

SELECT start_date, 
       end_date, 
       CASE 
         WHEN start_date <= '2015-08-31' THEN 'true' 
         ELSE 'false' 
       END AS started_before_end_of_month, 
       CASE 
         WHEN NOT end_date <= '2015-08-01' THEN 'true' 
         ELSE 'false' 
       END AS did_not_end_before_begining_of_month 
FROM   product_sales 
WHERE  start_date <= '2015-08-31' 
       AND end_date >= '2015-08-01' 
ORDER  BY start_date; 

No idea how you got your results, since it would not sort by string value... You should reverse a1 and a2 in your example

Best way in any case (as per Mladen) is:

metrics = {"sitea.com" => 745, "siteb.com" => 9, "sitec.com" => 10 }
metrics.sort_by {|_key, value| value}
  # ==> [["siteb.com", 9], ["sitec.com", 10], ["sitea.com", 745]]

If you need a hash as a result, you can use to_h (in Ruby 2.0+)

metrics.sort_by {|_key, value| value}.to_h
  # ==> {"siteb.com" => 9, "sitec.com" => 10, "sitea.com", 745}

You will get selected option's value and text from list/array by using filter.
editobj.FlagName=(EmployeeStatus|filter:{Value:editobj.Flag})[0].KeyName

<select name="statusSelect"
      id="statusSelect"
      class="form-control"
      ng-model="editobj.Flag"
      ng-options="option.Value as option.KeyName for option in EmployeeStatus"
      ng-change="editobj.FlagName=(EmployeeStatus|filter:{Value:editobj.Flag})[0].KeyName">
</select>

I faced a similar (but not identical) issue.

I had to go to to Turn Windows features on or off in Control Panel and add ASP.NET 3.5 and 4.7:

Then it worked for me.

jQlite (angular's "jQuery" port) doesn't support lookup by classes.

One solution would be to include jQuery in your app.

Another is using QuerySelector or QuerySelectorAll:

link: function(scope, element, attrs) {
   console.log(element[0].querySelector('.list-scrollable'))
}

We use the first item in the element array, which is the HTML element. element.eq(0) would yield the same.

It will Work Definitely...

just change your div width to 160px if you have a padding of 20px it adds 40px extra to the width of your div so you need to subtract 40px from the width in order to keep your div looking normal and not distorted with extra width on it and your text all messed up.

If your are going to replace all of the connection strings with news ones for production environment, you can simply replace all connection strings with production ones using this syntax:

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">

<connectionStrings xdt:Transform="Replace">
    <!-- production environment config --->
    <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true"
      providerName="System.Data.SqlClient" />
    <add name="Testing1" connectionString="Data Source=test;Initial Catalog=TestDatabase;Integrated Security=True"
      providerName="System.Data.SqlClient" />
</connectionStrings>

Found a comparison of the 2 techniques (query string vs file name) here:

Version as a querystring has two problems.

First, it may not always be a browser that implements caching through which we need to bust. It is said that certain (possibly older) proxies do ignore the querystring with respect to their caching behavior.

Second, in certain more complex deployment scenarios, where you have multiple frontend and/or multiple backend servers, an upgrade is anything but instantaneous. You need to be able to serve both the old and the new version of your assets at the same time. See for example how this affects you when using Google App Engine.

Updated for Angular2 RC4:

import {HostListener, Directive, Input} from '@angular/core';

@Directive({
    selector: '[href]'
})
export class PreventDefaultLinkDirective {

    @Input() href;
    @HostListener('click', ['$event']) onClick(event) {this.preventDefault(event);}

    private preventDefault(event) {
        if (this.href.length === 0 || this.href === '#') {
            event.preventDefault();
        }
    }
}

Using

bootstrap(App, [provide(PLATFORM_DIRECTIVES, {useValue: PreventDefaultLinkDirective, multi: true})]);

In my case (php page on OVH mutualisé server) enctype="text/plain" does not work ($_POST and corresponding $_REQUEST is empty), the other examples below work. `

<form action="?" method="post">
<!-- in this case, my google chrome 45.0.2454.101 uses -->
<!--     Content-Type:application/x-www-form-urlencoded -->
    <input name="say" value="Hi">
    <button>Send my greetings</button>
</form>

<form action="?" method="post" enctype="application/x-www-form-urlencoded">
    <input name="say" value="Hi">
    <button>Send my application/x-www-form-urlencoded greetings</button>
</form>

<form action="?" method="post"  enctype="multipart/form-data">
    <input name="say" value="Hi">
    <button>Send my multipart/form-data greetings</button>
</form>

<form action="?" method="post" enctype="text/plain"><!-- not working -->
    <input name="say" value="Hi">
    <button>Send my text/plain greetings</button>
</form>

`

More here: method="post" enctype="text/plain" are not compatible?

An alternative:

var scrollleft = 1000;
switch (true)
{
    case (scrollleft > 1000):
      alert('gt');
      break;
    case (scrollleft <= 1000):
      alert('lt');
      break; 
}

Ok, so let's try a combination of all the answers and updates so far and do something like this:

• Add the ACCESS_FINE_LOCATION permission to your manifest
• Get an instance of the system LocationManager
• Create a GpsStatus.Listener that reacts to GPS_EVENT_SATELLITE_STATUS
• Register the listener with LocationManager with addGpsStatusListener

The GPS listener could be something like this:

GpsStatus.Listener listener = new GpsStatus.Listener() {
    void onGpsStatusChanged(int event) {
        if (event == GPS_EVENT_SATELLITE_STATUS) {
            GpsStatus status = mLocManager.getGpsStatus(null);
            Iterable<GpsSatellite> sats = status.getSatellites();
            // Check number of satellites in list to determine fix state
        }
    }
}

The APIs are a bit unclear about when and what GPS and satellite information is given, but I think an idea would be to look at how many satellites are available. If it's below three, then you can't have a fix. If it's more, then you should have a fix.

Trial and error is probably the way to go to determine how often Android reports satellite info, and what info each GpsSatellite object contains.

try:

string fileName = @"test.txt";
    string currentDirectory = Directory.GetCurrentDirectory();
    string[] fullFilePath = Directory.GetFiles(currentDirectory, filename, SearchOption.AllDirectories);

it will return full path of all such files in the current directory and its sub directories to string array fullFilePath. If only one file exist it will be in "fullFileName[0]".

UPDATE: The following explanation is for one Android Studio project, with one Firebase Project and different Firebase Apps inside that project. If the aim is to have different JSON files for different Firebase Apps in different Firebase Projects inside the same Android Studio project, (or if you don't know what's the difference) look here..

You need one Firebase App per Android Application ID (usually package name). Is common to have one Application ID per Gradle build variant (This is gonna be likely if you use Gradle build types and Gradle build flavours)

As of Google Services 3.0 and using Firebase it's not necessary to create different files for different flavours. Creating different files for different flavours can be not clear or straightforward in case you have productFlavours and Build types which compose with each other.

In the same file you'll have the all the configurations you need for all your build types and flavours.

In the Firebase console you need to add one app per package name. Imagine that you have 2 flavours (dev and live) and 2 build types (debug and release). Depending on your config but it's likely that you have 4 different package names like:

• com.stackoverflow.example (live - release)
• com.stackoverflow.example.dev (live - dev)
• com.stackoverflow.example.debug (debug - release)
• com.stackoverflow.example.dev.debug (debug - dev)

You need 4 different Android Apps in the Firebase Console. (On each one you need to add the SHA-1 for debug and live for each computer you are using)

When you download the google-services.json file, actually it doesn't really matter from what app you download it, all of them contain the same info related to all your apps.

Now you need to locate this file in app level (app/).

If you open that file you'll see that if contains all the information for all your package names.

A pain point use to be the plugin. In order to get it working you need to locate the plugin at the bottom of your file. So this line..

apply plugin: 'com.google.gms.google-services'

...needs to be on the bottom of your app build.gradle file.

For most of the said here, it applies to previous versions as well. I've never had different files for different configs, but now with the Firebase console is easier because they provide one single file with everything you need for all you configs.

I hope it will resolve your problem

In general you just have to define a slightly transparent color when creating the shape.

You can achieve that by setting the colors alpha channel.

#FF000000 will get you a solid black whereas #00000000 will get you a 100% transparent black (well it isn't black anymore obviously).

The color scheme is like this #AARRGGBB there A stands for alpha channel, R stands for red, G for green and B for blue.

The same thing applies if you set the color in Java. There it will only look like 0xFF000000.

UPDATE

In your case you'd have to add a solid node. Like below.

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/shape_my">
    <stroke android:width="4dp" android:color="#636161" />
    <padding android:left="20dp"
        android:top="20dp"
        android:right="20dp"
        android:bottom="20dp" />
    <corners android:radius="24dp" />
    <solid android:color="#88000000" />
</shape>

The color here is a half transparent black.

You are not actually changing the function.

onClick is assigned to a function (Which is a reference to something, a function pointer in this case). The values passed to it don't matter and cannot be utilised in any manner.

Another problem is your variable color seems out of nowhere.

Ideally, inside the function you should put this logic and let it figure out what to write. (on/off etc etc)

I faced same issue even after rebuilding my project multiple times successfully. I closed the project and re-opened, issue resolved.
