As far as I know, it's not possible to change the content of the buttons, at least not easily. It's fairly easy to have your own custom alert box using JQuery UI though

Obs.: Changing http.postBuffer might also require to set up the Nginx configuration file for gitlab to accept larger body sizes for the client, by tuning the value of client_max_body_size.

However, there is a workaround if you have access to the Gitlab machine or to a machine in its network, and that is by making use of git bundle.

1. go to your git repository on the source machine
2. run git bundle create my-repo.bundle --all
3. transfer (eg., with rsync) the my-repo.bundle file to the destination machine
4. on the destination machine, run git clone my-repo.bundle
5. git remote set-url origin "path/to/your/repo.git"
6. git push

All the best!

Even if the following proposal should not be considered as a final solution you can achieve the goal by doing something like this:

SET SESSION group_concat_max_len = 1000000;
SET @search = 'Text_To_Search';

DROP table IF EXISTS table1;
CREATE TEMPORARY TABLE table1 AS 
(SELECT 
    CONCAT('SELECT \'',TABLE_NAME,'\' as \'table_name\',\'',COLUMN_NAME,'\' as \'column_name\',CONVERT(count(*),char) as \'matches\' FROM `',
    TABLE_NAME,'` where `',COLUMN_NAME,'` like \'%',@search,'%\' UNION ') as 'query'
FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'db_name' limit 1000000);

set @query = (SELECT GROUP_CONCAT(t1.`query` SEPARATOR '') as 'final_query' from table1 t1 limit 1);
set @query = (SELECT SUBSTRING(@query, 1, length(@query) - 7));

PREPARE stmt FROM @query;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

Please remember that:

1. Options: group_concat_max_len and limit 1000000 not always are needed, it will depends of your server/IDE configuration. Just in case I added them.

2. After executing this you will get a 3 column response: [table_name], [column_name], [matches]

3. Column 'matches' is the number of occurrences in the given table/column.

4. This query is very fast.

DISCLAIMER: It would be useful only for personal use, in other words please don't use it in a production system, because it is sensitive to SQL Injection attacks given that the search parameter is concatenated with other strings. If you want to create a prod. ready function, then you will need to create a store procedure with a LOOP.

Arrays.sort(persons, new PersonComparator());



import java.util.Comparator;

public class PersonComparator implements Comparator<? extends Person> {

    @Override
    public int compare(Person o1, Person o2) {
        if(null == o1 || null == o2  || null == o1.getName() || null== o2.getName() ){
            throw new NullPointerException();
        }else{
            int nameComparisonResult = o1.getName().compareTo(o2.getName());
            if(0 == nameComparisonResult){
                return o1.getAge()-o2.getAge();
            }else{
                return nameComparisonResult;
            }
        }
    }
}


class Person{
    int age; String name;

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

Updated version:

public class PersonComparator implements Comparator<? extends Person> {

   @Override
   public int compare(Person o1, Person o2) {

      int nameComparisonResult = o1.getName().compareToIgnoreCase(o2.getName());
      return 0 == nameComparisonResult?o1.getAge()-o2.getAge():nameComparisonResult;

   }
 }

the proper implementation would be:

if( callback ) callback();

this makes the callback parameter optional..

As @markE mention in his answer

the alternative is to untranslate & unrotate after drawing

It is much faster than context save and restore.

Here is an example

// translate and rotate
this.context.translate(x,y);
this.context.rotate(radians);
this.context.translate(-x,-y);

this.context.drawImage(...);    

// untranslate and unrotate
this.context.translate(x, y);
this.context.rotate(-radians);
this.context.translate(-x,-y);

It "maps" a function to each item in an Enumerable - in this case, a range. So it would call the block passed once for every integer from 0 to param_count (exclusive - you're right about the dots) and return an array containing each return value.

Here's the documentation for Enumerable#map. It also has an alias, collect.

contentType: 'application/x-www-form-urlencoded'

With objectiveC

[self.superview.constraints enumerateObjectsUsingBlock:^(__kindof NSLayoutConstraint * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        NSLayoutConstraint *constraint = (NSLayoutConstraint *)obj;
        if (constraint.firstItem == self || constraint.secondItem == self) {
            [self.superview removeConstraint:constraint];
        }
    }];
    [self removeConstraints:self.constraints];
}

Just pass it as an argument of findAll:

>>> from BeautifulSoup import BeautifulSoup
>>> soup = BeautifulSoup("""
... <html>
... <head><title>My Title!</title></head>
... <body><table>
... <tr><td>First!</td>
... <td valign="top">Second!</td></tr>
... </table></body><html>
... """)
>>>
>>> soup.findAll('td')
[<td>First!</td>, <td valign="top">Second!</td>]
>>>
>>> soup.findAll('td', valign='top')
[<td valign="top">Second!</td>]

Since docstrings are free-form, it really depends on what you use to parse code to generate API documentation.

I would recommend getting familiar with the Sphinx markup, since it is widely used and is becoming the de-facto standard for documenting Python projects, in part because of the excellent readthedocs.org service. To paraphrase an example from the Sphinx documentation as a Python snippet:

def send_message(sender, recipient, message_body, priority=1):
   '''
   Send a message to a recipient

   :param str sender: The person sending the message
   :param str recipient: The recipient of the message
   :param str message_body: The body of the message
   :param priority: The priority of the message, can be a number 1-5
   :type priority: integer or None
   :return: the message id
   :rtype: int
   :raises ValueError: if the message_body exceeds 160 characters
   :raises TypeError: if the message_body is not a basestring
   '''

This markup supports cross-referencing between documents and more. Note that the Sphinx documentation uses (e.g.) :py:attr: whereas you can just use :attr: when documenting from the source code.

Naturally, there are other tools to document APIs. There's the more classic Doxygen which uses \param commands but those are not specifically designed to document Python code like Sphinx is.

Note that there is a similar question with a similar answer in here...

For iPhone it works if you add also playsinline so:

<video width="320" height="240" autoplay loop muted playsinline>
  <source src="movie.mp4" type="video/mp4" />
</video>

try this:

ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#0000ff")));

Depending on the size and number of files being copied, you could copy the destination directory over the source first with "yes to all", then do the original copy you were doing, also with "yes to all" set. That should give you the same results.

An expansion on Eran's answer that was the top answer, if you have a bunch of layers of lists, you can keep flatmapping them.

This also comes with a handy way of filtering as you go down the layers if needed as well.

So for example:

List<List<List<List<List<List<Object>>>>>> multiLayeredList = ...

List<Object> objectList = multiLayeredList
    .stream()
    .flatmap(someList1 -> someList1
        .stream()
        .filter(...Optional...))
    .flatmap(someList2 -> someList2
        .stream()
        .filter(...Optional...))
    .flatmap(someList3 -> someList3
        .stream()
        .filter(...Optional...))
    ...
    .collect(Collectors.toList())

This is would be similar in SQL to having SELECT statements within SELECT statements.

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

In Qt 4.7, there is the QDateTime::currentMSecsSinceEpoch() static function, which does exactly what you need, without any intermediary steps. Hence I'd recommend that for projects using Qt 4.7 or newer.

Considering this still shows up when we search for EF in .NET Core, I'll post my answer here (Since it has haunted me a lot). Note that there are some subtleties with the EF 6 .NET version (No initial command, and you will need to delete "Snapshot" files)

(Tested in .NET Core 2.1)

Here are the steps:

1. Delete the _efmigrationhistory table.
2. Search for your entire solution for files that contain Snapshot in their name, such as ApplicationDbContextSnapshot.cs, and delete them.
3. Rebuild your solution
4. Run Add-Migration InitialMigration

Please note: You must delete ALL the Snapshot files. I spent countless hours just deleting the database... This will generate an empty migration if you don't do it.

Also, in #3 you can just name your migration however you want.

Here are some additional resources: asp.net CORE Migrations generated empty

Try using the :input selector, along with a parent selector:

$("#parent-selector :input").attr("disabled", true);

User Pumbaa80's answer is great if you have an object you want pretty printed. If you're starting from a valid JSON string that you want to pretty printed, you need to convert it to an object first:

var jsonString = '{"some":"json"}';
var jsonPretty = JSON.stringify(JSON.parse(jsonString),null,2);  

This builds a JSON object from the string, and then converts it back to a string using JSON stringify's pretty print.

I downloaded ant (http://ant.apache.org/bindownload.cgi), unzipped to my C drive, and used the windows 'doskey' command:

doskey ant=C:\apache-ant-1.9.6\bin\ant.bat $*

this will work as long as you use the same command console, to make it permanent is more difficult: http://darkforge.blogspot.com/2010/08/permanent-windows-command-line-aliases.html

((\.|^)(25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]?|0$)){4}

This regex will not accept 08.8.8.8 or 8.08.8.8 or 8.8.08.8 or 8.8.8.08

So the real answer to

Can this programmer now unstage his last changes with some magical git command?

is actually: No, you cannot unstage just the last git add.

That is if we interpret the question as in the following situation:

Initial file:

void foo() {

}

main() {
    foo();
}

First change followed by git add:

void foo(int bar) {
    print("$bar");
}

main() {
    foo(1337);
}

Second change followed by git add:

void foo(int bar, String baz) {
    print("$bar $baz");
}

main() {
    foo(1337, "h4x0r");
}

In this case, git reset -p will not help, since its smallest granularity is lines. git doesn't know that about the intermediate state of:

void foo(int bar) {
    print("$bar");
}

main() {
    foo(1337);
}

any more.

try this:

var count_element = $('.element').length

you can either reuse the docker shell, with eval $(minikube docker-env), alternatively, you can leverage on docker save | docker load across the shells.

In BBEdit works this (ex.: changing the ID values to lowercase):

Search any value: <a id="(?P<x>.*?)"></a> Replace with the same in lowercase: <a id="\L\P<x>\E"></a>

Was: <a id="VALUE"></a> Became: <a id="value"></a>

There is a new API that makes this even simpler.

plt.gca().invert_xaxis()

and/or

plt.gca().invert_yaxis()

CREATE FUNCTION ActionState_Preassigned()
RETURNS tinyint
AS
BEGIN
    RETURN 0
END

GO

CREATE FUNCTION ActionState_Unassigned()
RETURNS tinyint
AS
BEGIN
    RETURN 1
END

-- etc...

Where performance matters, still use the hard values.

If it's worth adding another file / dependency to your project, I've just written a tiny little class that extends datetime.time with the ability to do arithmetic. When you go past midnight, it wraps around zero. Now, "What time will it be, 24 hours from now" has a lot of corner cases, including daylight savings time, leap seconds, historical timezone changes, and so on. But sometimes you really do need the simple case, and that's what this will do.

Your example would be written:

>>> import datetime
>>> import nptime
>>> nptime.nptime(11, 34, 59) + datetime.timedelta(0, 3)
nptime(11, 35, 2)

nptime inherits from datetime.time, so any of those methods should be usable, too.

It's available from PyPi as nptime ("non-pedantic time"), or on GitHub: https://github.com/tgs/nptime

for(map<string, pair<string,string> >::const_iterator it = myMap.begin();
    it != myMap.end(); ++it)
{
    std::cout << it->first << " " << it->second.first << " " << it->second.second << "\n";
}

In C++11, you don't need to spell out map<string, pair<string,string> >::const_iterator. You can use auto

for(auto it = myMap.cbegin(); it != myMap.cend(); ++it)
{
    std::cout << it->first << " " << it->second.first << " " << it->second.second << "\n";
}

Note the use of cbegin() and cend() functions.

Easier still, you can use the range-based for loop:

for(auto elem : myMap)
{
   std::cout << elem.first << " " << elem.second.first << " " << elem.second.second << "\n";
}

var DateDiff = function(type, start, end) {

    let // or var
        years = end.getFullYear() - start.getFullYear(),
        monthsStart = start.getMonth(),
        monthsEnd = end.getMonth()
    ;

    var returns = -1;

    switch(type){
        case 'm': case 'mm': case 'month': case 'months':
            returns = ( ( ( years * 12 ) - ( 12 - monthsEnd ) ) + ( 12 - monthsStart ) );
            break;
        case 'y': case 'yy': case 'year': case 'years':
            returns = years;
            break;
        case 'd': case 'dd': case 'day': case 'days':
            returns = ( ( end - start ) / ( 1000 * 60 * 60 * 24 ) );
            break;
    }

    return returns;

}

Usage

var qtMonths = DateDiff('mm', new Date('2015-05-05'), new Date());

var qtYears = DateDiff('yy', new Date('2015-05-05'), new Date());

var qtDays = DateDiff('dd', new Date('2015-05-05'), new Date());

OR

var qtMonths = DateDiff('m', new Date('2015-05-05'), new Date()); // m || y || d

var qtMonths = DateDiff('month', new Date('2015-05-05'), new Date()); // month || year || day

var qtMonths = DateDiff('months', new Date('2015-05-05'), new Date()); // months || years || days

...

var DateDiff = function (type, start, end) {

    let // or var
        years = end.getFullYear() - start.getFullYear(),
        monthsStart = start.getMonth(),
        monthsEnd = end.getMonth()
    ;

    if(['m', 'mm', 'month', 'months'].includes(type)/*ES6*/)
        return ( ( ( years * 12 ) - ( 12 - monthsEnd ) ) + ( 12 - monthsStart ) );
    else if(['y', 'yy', 'year', 'years'].includes(type))
        return years;
    else if (['d', 'dd', 'day', 'days'].indexOf(type) !== -1/*EARLIER JAVASCRIPT VERSIONS*/)
        return ( ( end - start ) / ( 1000 * 60 * 60 * 24 ) );
    else
        return -1;

}

So, the concept of a "wildcard" in Regular Expressions works a bit differently. In order to match "any character" you would use "." The "*" modifier means, match any number of times.

For Back Button in jquery // http://code.jquery.com/jquery-latest.js

 jQuery(window).bind("unload", function() { //

and in html5 there is an event The event is called 'popstate'

window.onpopstate = function(event) {
alert("location: " + document.location + ", state: " + JSON.stringify(event.state));
};

and for refresh please check Check if page gets reloaded or refreshed in Javascript

By this method also you can compare two dates

NSDate * dateOne = [NSDate date];
NSDate * dateTwo = [NSDate date];

if([dateOne compare:dateTwo] == NSOrderedAscending)
{

Here is a more general answer for future viewers of this question. The layout we will make is below:

Method 1: Add TextView to existing LinearLayout

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.dynamic_linearlayout);

    LinearLayout linearLayout = (LinearLayout) findViewById(R.id.ll_example);

    // Add textview 1
    TextView textView1 = new TextView(this);
    textView1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
            LayoutParams.WRAP_CONTENT));
    textView1.setText("programmatically created TextView1");
    textView1.setBackgroundColor(0xff66ff66); // hex color 0xAARRGGBB
    textView1.setPadding(20, 20, 20, 20);// in pixels (left, top, right, bottom)
    linearLayout.addView(textView1);

    // Add textview 2
    TextView textView2 = new TextView(this);
    LayoutParams layoutParams = new LayoutParams(LayoutParams.WRAP_CONTENT,
            LayoutParams.WRAP_CONTENT);
    layoutParams.gravity = Gravity.RIGHT;
    layoutParams.setMargins(10, 10, 10, 10); // (left, top, right, bottom)
    textView2.setLayoutParams(layoutParams);
    textView2.setText("programmatically created TextView2");
    textView2.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);
    textView2.setBackgroundColor(0xffffdbdb); // hex color 0xAARRGGBB
    linearLayout.addView(textView2);
}

Note that for LayoutParams you must specify the kind of layout for the import, as in

import android.widget.LinearLayout.LayoutParams;

Otherwise you need to use LinearLayout.LayoutParams in the code.

Here is the xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ll_example"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ff99ccff"
    android:orientation="vertical" >

</LinearLayout>

Method 2: Create both LinearLayout and TextView programmatically

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // NOTE: setContentView is below, not here

    // Create new LinearLayout
    LinearLayout linearLayout = new LinearLayout(this);
    linearLayout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
            LayoutParams.MATCH_PARENT));
    linearLayout.setOrientation(LinearLayout.VERTICAL);
    linearLayout.setBackgroundColor(0xff99ccff);

    // Add textviews
    TextView textView1 = new TextView(this);
    textView1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
            LayoutParams.WRAP_CONTENT));
    textView1.setText("programmatically created TextView1");
    textView1.setBackgroundColor(0xff66ff66); // hex color 0xAARRGGBB
    textView1.setPadding(20, 20, 20, 20); // in pixels (left, top, right, bottom)
    linearLayout.addView(textView1);

    TextView textView2 = new TextView(this);
    LayoutParams layoutParams = new LayoutParams(LayoutParams.WRAP_CONTENT,
            LayoutParams.WRAP_CONTENT);
    layoutParams.gravity = Gravity.RIGHT;
    layoutParams.setMargins(10, 10, 10, 10); // (left, top, right, bottom)
    textView2.setLayoutParams(layoutParams);
    textView2.setText("programmatically created TextView2");
    textView2.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);
    textView2.setBackgroundColor(0xffffdbdb); // hex color 0xAARRGGBB
    linearLayout.addView(textView2);

    // Set context view
    setContentView(linearLayout);
}

Method 3: Programmatically add one xml layout to another xml layout

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.dynamic_linearlayout);

    LayoutInflater inflater = (LayoutInflater) getApplicationContext().getSystemService(
            Context.LAYOUT_INFLATER_SERVICE);
    View view = inflater.inflate(R.layout.dynamic_linearlayout_item, null);
    FrameLayout container = (FrameLayout) findViewById(R.id.flContainer);
    container.addView(view);
}

Here is dynamic_linearlayout.xml:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/flContainer"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

</FrameLayout>

And here is the dynamic_linearlayout_item.xml to add:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ll_example"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ff99ccff"
    android:orientation="vertical" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#ff66ff66"
        android:padding="20px"
        android:text="programmatically created TextView1" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#ffffdbdb"
        android:layout_gravity="right"
        android:layout_margin="10px"
        android:textSize="18sp"
        android:text="programmatically created TextView2" />

</LinearLayout>

check the command : NA!=NA : you'll get the result NA, hence the error message.

You have to use the function is.na for your ifstatement to work (in general, it is always better to use this function to check for NA values) :

comments = c("no","yes",NA)
for (l in 1:length(comments)) {
    if (!is.na(comments[l])) print(comments[l])
}
[1] "no"
[1] "yes"

Give the div you don't want him inheriting the property background too.

You cannot safely do what you want since the default hashCode() may not return the address, and has been mentioned, multiple objects with the same hashCode are possible. The only way to accomplish what you want, is to actually override the hashCode() method for the objects in question and guarantee that they all provide unique values. Whether this is feasible in your situation is another question.

For the record, I have experienced multiple objects with the same default hashcode in an IBM VM running in a WAS server. We had a defect where objects being put into a remote cache would get overwritten because of this. That was an eye opener for me at that point since I assumed the default hashcode was the objects memory address as well.

First

Make a dir c:\command

Second Make a ll.bat

ll.bat

dir

Third Add to Path C:/commands

I think you should add style="background:white;" to make looks like it is writable

<input type="text" size="23" name="dateMonthly" id="dateMonthly" readonly="readonly"   style="background:white;"/>

Simple copy & paste example with subqueries, Note, that both queries should return 1 row:

select
(select sum(items_1) from items_table_1 where ...)
-
(select count(items_2) from items_table_1 where ...) 

as difference

Let's expand defer() from Dario to be more reusable.

function defer(toWaitFor, method) {
    if (window[toWaitFor]) {
        method();
    } else {
        setTimeout(function () { defer(toWaitFor, method) }, 50);
    }
}

Which is then run:

function waitFor() {
    defer('jQuery', () => {console.log('jq done')});
    defer('utag', () => {console.log('utag done')});
}

I figured out the issue. The linked server was created correctly. However, after the server was upgraded and switched the server name in sys.servers still had the old server name.

I had to drop the old server name and add the new server name to sys.servers on the new server

sp_dropserver 'Server_A'
GO
sp_addserver  'Server',local
GO

Deferred promises are a nice way to chain together function execution neatly and easily. Whether AJAX or normal functions, they offer greater flexibility than callbacks, and I've found easier to grasp.

function Typer()
{
var dfd = $.Deferred();
    var srcText = 'EXAMPLE ';
    var i = 0;
    var result = srcText[i];

UPDATE :

////////////////////////////////

  var timer=    setInterval(function() {
                    if(i == srcText.length) {

    // clearInterval(this);


       clearInterval(timer);

I've modified the play function so it returns a promise when the audio finishes playing, which might be useful to some. The third function fires when sound finishes playing.

   function playBGM()
    {
      var playsound = $.Deferred();
      $('#bgm')[0].play();
      $("#bgm").on("ended", function() {
         playsound.resolve();
      });
        return playsound.promise();
    }


    function thirdFunction() {
        alert('third function');
    }

Now call the whole thing with the following: (be sure to use Jquery 1.9.1 or above as I found that 1.7.2 executes all the functions at once, rather than waiting for each to resolve.)

Typer().then(playBGM).then(thirdFunction);  

Before today, I had no luck using deferred promises in this way, and finally have grasped it. Precisely timed, chained interface events occurring exactly when we want them to, including async events, has never been easy. For me at least, I now have it under control thanks largely to others asking questions here.

Here is a plugin for PhoneGap which solved the problem for me: https://build.phonegap.com/plugins/1031

I simply included it in my config.xml

In simple terms,

1. static : static variables are associated with the class, rather than with any object. Every instance of the class shares a class variable, which is in one fixed location in memory

2. volatile: This keyword is applicable to both class and instance variables.

Using volatile variables reduces the risk of memory consistency errors, because any write to a volatile variable establishes a happens-before relationship with subsequent reads of that same variable. This means that changes to a volatile variable are always visible to other threads

Have a look at this article by Javin Paul to understand volatile variables in a better way.

In absence of volatile keyword, the value of variable in each thread's stack may be different. By making the variable as volatile, all threads will get same value in their working memory and memory consistency errors have been avoided.

Here the term variable can be either static (class) variable or instance (object) variable.

Regarding your query :

Anyway a static variable value is also going to be one value for all threads, then why should we go for volatile?

If I need instance variable in my application, I can't use static variable. Even in case of static variable, consistency is not guaranteed due to Thread cache as shown in the diagram.

Using volatile variables reduces the risk of memory consistency errors, because any write to a volatile variable establishes a happens-before relationship with subsequent reads of that same variable. This means that changes to a volatile variable are always visible to other threads.

What's more, it also means that when a thread reads a volatile variable, it sees not just the latest change to the volatile, but also the side effects of the code that led up the change => memory consistency errors are still possible with volatile variables. To avoid side effects, you have to use synchronized variables. But there is a better solution in java.

Using simple atomic variable access is more efficient than accessing these variables through synchronized code

Some of the classes in the java.util.concurrent package provide atomic methods that do not rely on synchronization.

Refer to this high level concurrency control article for more details.

Especially have a look at Atomic variables.

Update C# 7

Yes: Source

        WriteLine($"circle with radius {c.Radius}");
        break;
    case Rectangle s when (s.Length == s.Height):

No.

http://blogs.msdn.com/b/peterhal/archive/2005/07/05/435760.aspx

We get a lot of requests for addditions to the C# language and today I'm going to talk about one of the more common ones - switch on type. Switch on type looks like a pretty useful and straightforward feature: Add a switch-like construct which switches on the type of the expression, rather than the value. This might look something like this:

switch typeof(e) { 
        case int:    ... break; 
        case string: ... break; 
        case double: ... break; 
        default:     ... break; 
}

This kind of statement would be extremely useful for adding virtual method like dispatch over a disjoint type hierarchy, or over a type hierarchy containing types that you don't own. Seeing an example like this, you could easily conclude that the feature would be straightforward and useful. It might even get you thinking "Why don't those #*&%$ lazy C# language designers just make my life easier and add this simple, timesaving language feature?"

Unfortunately, like many 'simple' language features, type switch is not as simple as it first appears. The troubles start when you look at a more significant, and no less important, example like this:

class C {}
interface I {}
class D : C, I {}

switch typeof(e) {
case C: … break;
case I: … break;
default: … break;
}

Link: https://blogs.msdn.microsoft.com/peterhal/2005/07/05/many-questions-switch-on-type/

Here is a simple, compact and easy to understand method I use.
First, add a service in your js.

app.factory('Helpers', [ function() {
      // Helper service body

        var o = {
        Helpers: []

        };

        // Dummy function with parameter being passed
        o.getFooBar = function(para) {

            var valueIneed = para + " " + "World!";

            return valueIneed;

          };

        // Other helper functions can be added here ...

        // And we return the helper object ...
        return o;

    }]);

Then, in your controller, inject your helper object and use any available function with something like the following:

app.controller('MainCtrl', [

'$scope',
'Helpers',

function($scope, Helpers){

    $scope.sayIt = Helpers.getFooBar("Hello");
    console.log($scope.sayIt);

}]);

Beauty in one line:

ls -v | cat -n | while read n f; do mv -n "$f" "$n.ext"; done 

You can change .ext with .png, .jpg, etc.

Traversal over the large map entrySet() is much better than the keySet(). Check this tutorial how they optimise the traversal over the large object with the help of entrySet() and how it helps for performance tuning.

In my case it was broken config for mysqlnd_ms php extension on the server. Funny thing is that it was working fine on requests with short duration. There was a warning in server error log, so we have fixed it quick.

I always set the max like this:

    <EditText
        android:id="@+id/edit_blaze_it
        android:layout_width="0dp"
        android:layout_height="@dimen/too_high"

    <!-- This is the line you need to write to set the max-->
        android:maxLength="420"
        />

The following code returns the wanted "folder" as Path regardless of if it is inside a jar or not.

  private Path getFolderPath() throws URISyntaxException, IOException {
    URI uri = getClass().getClassLoader().getResource("folder").toURI();
    if ("jar".equals(uri.getScheme())) {
      FileSystem fileSystem = FileSystems.newFileSystem(uri, Collections.emptyMap(), null);
      return fileSystem.getPath("path/to/folder/inside/jar");
    } else {
      return Paths.get(uri);
    }
  }

Requires java 7+.

Maybe there's a more simple answer, try to add any background color you like to the code, like background-color: #fff;

#alpha {
 background-color: #fff;
 opacity: 0.8;
 filter: alpha(opacity=80);
}

Another clean method with a small controller, two views and a partial view :

UsersController.php

public function create()
{
    return View::('create');
}    

public function edit($id)
{
    $user = User::find($id);
    return View::('edit')->with(compact('user'));
}

create.blade.php

{{ Form::open( array( 'route' => ['users.index'], 'role' => 'form' ) ) }}
    @include('_fields')
{{ Form::close() }}

edit.blade.php

{{ Form::model( $user, ['route' => ['users.update', $user->id], 'method' => 'put', 'role' => 'form'] ) }}
    @include('_fields')
{{ Form::close() }}

_fields.blade.php

{{ Form::text('fieldname1') }}
{{ Form::text('fieldname2') }}
{{ Form::button('Save', ['type' => 'submit']) }}

So the problem is connected with the metadata errors of elcipse. Go to the metadata folder where this configuration is saved. For me one of the erorrs was that:

SEVERE: Error starting static Resources java.lang.IllegalArgumentException: Document base C:\Users\Cannibal\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\FoodQuantityService does not exist or is not a readable directory

So go there is in the workspace of your eclipse it is different for all and delete all its content . My services was named FoodQuantityService so I deleted all files in org.eclipse.wst.server.core but before that delete your server configuration from Eclipse

Then create new configuration File->New->Other->Server select Tomcat and then projects which you want to be published. Start the server and everything will be ok.

Regex's shouldn't really be used in this fashion - unless you want something more complicated than what you're trying to do - for instance, you could just normalise your content string and comparision string to be:

if 'facebook.com' in content.lower():
    shutil.copy(x, "C:/Users/David/Desktop/Test/MyFiles2")

echo "$string" | tr xyz _

would replace each occurrence of x, y, or z with _, giving A__BC___DEF__LMN in your example.

echo "$string" | sed -r 's/[xyz]+/_/g'

would replace repeating occurrences of x, y, or z with a single _, giving A_BC_DEF_LMN in your example.

I had also been through that problem. in my case, I was adding the data to the array and passing the array to the same array which brings the problem of memory limits. Some of the things you need to consider:

1. Review our code, look if any loop is running infinity.

2. Reduce the unwanted column if you are retrieving the data from the database.

3. Maybe you can increase the memory limits in our XAMPP other any other software you are running.

Below will reinitialize your local repo; also clearing remote repos (ie origin):

git init

Then below, will create 'origin' if it doesn't exist:

git remote add origin [repo-url]

Else, you can use the set-url subcommand to edit an existing remote:

git remote set-url origin [repo-url]

Also, you can check existing remotes with

git remote -v

Hope this helps!

You can see all the privileges for all directories wit the following

SELECT *
from all_tab_privs
where table_name in
  (select directory_name 
   from dba_directories);

The following gives you the sql statements to grant the privileges should you need to backup what you've done or something

select 'Grant '||privilege||' on directory '||table_schema||'.'||table_name||' to '||grantee 
from all_tab_privs 
where table_name in (select directory_name from dba_directories);

You can use optional parameters in C# 4.0 without any worries. If we have a method like:

int MyMetod(int param1, int param2, int param3=10, int param4=20){....}

when you call the method, you can skip parameters like this:

int variab = MyMethod(param3:50; param1:10);

C# 4.0 implements a feature called "named parameters", you can actually pass parameters by their names, and of course you can pass parameters in whatever order you want :)

This:

document.getElementById('myField').onblur();

works because your element (the <input>) has an attribute called "onblur" whose value is a function. Thus, you can call it. You're not telling the browser to simulate the actual "blur" event, however; there's no event object created, for example.

Elements do not have a "blur" attribute (or "method" or whatever), so that's why the first thing doesn't work.

test="categoryName != ''"

Edit: This covers the most likely interpretation, in my opinion, of "[not] null or empty" as inferred from the question, including it's pseudo-code and my own early experience with XSLT. I.e., "What is the equivalent of the following Java?":

!(categoryName == null || categoryName.equals(""))

For more details e.g., distinctly identifying null vs. empty, see johnvey's answer below and/or the XSLT 'fiddle' I've adapted from that answer, which includes the option in Michael Kay's comment as well as the sixth possible interpretation.

You can use sqlcmd to run a backup, or any other T-SQL script. You can find the detailed instructions and examples on various useful sqlcmd switches in this article: Working with the SQL Server command line (sqlcmd)

In Python there's no POSIX regex classes

There are when using the regex library: https://pypi.org/project/regex/

It is well maintained and supports Unicode regex, Posix regex and many more. The usage (method signatures) is very similar to Python's re.

From the documentation:

[[:alpha:]]; [[:^alpha:]]

POSIX character classes are supported. These are normally treated as an alternative form of \p{...}.

(I'm not affiliated, just a user.)

You can also use CURRENT_TIMESTAMP for this.

According to BOL CURRENT_TIMESTAMP is the ANSI SQL euivalent to GETDATE()

DECLARE @LastChangeDate AS DATE;
SET @LastChangeDate = CURRENT_TIMESTAMP;

There are two problems with your attempt.

First, you've used n+1 instead of i+1, so you're going to return something like [5, 5, 5, 5] instead of [1, 2, 3, 4].

Second, you can't for-loop over a number like n, you need to loop over some kind of sequence, like range(n).

So:

def naturalNumbers(n):
    return [i+1 for i in range(n)]

But if you already have the range function, you don't need this at all; you can just return range(1, n+1), as arshaji showed.

So, how would you build this yourself? You don't have a sequence to loop over, so instead of for, you have to build it yourself with while:

def naturalNumbers(n):
    results = []
    i = 1
    while i <= n:
        results.append(i)
        i += 1
    return results

Of course in real-life code, you should always use for with a range, instead of doing things manually. In fact, even for this exercise, it might be better to write your own range function first, just to use it for naturalNumbers. (It's already pretty close.)

There is one more option, if you want to get clever.

If you have a list, you can slice it. For example, the first 5 elements of my_list are my_list[:5]. So, if you had an infinitely-long list starting with 1, that would be easy. Unfortunately, you can't have an infinitely-long list… but you can have an iterator that simulates one very easily, either by using count or by writing your own 2-liner equivalent. And, while you can't slice an iterator, you can do the equivalent with islice. So:

from itertools import count, islice
def naturalNumbers(n):
    return list(islice(count(1), n))

Use the -H header again before the Authorization:Basic things. So it will be

curl -i \
    -H 'Accept:application/json' \
    -H 'Authorization:Basic BASE64_string' \
    http://example.com

Here, BASE64_string = Base64 of username:password

function truncate(input) {
   if (input.length > 5) {
      return input.substring(0, 5) + '...';
   }
   return input;
};

or in ES6

const truncate = (input) => input.length > 5 ? `${input.substring(0, 5)}...` : input;

Apparently the correct form is without the ""

As in

set JAVA_OPTS=-Xms512M -Xmx1024M

I'm using this:

if(count($array)==count(array_count_values($array))){
    echo("all values are unique");
}else{
    echo("there's dupe values");
}

I don't know if it's the fastest but works pretty good so far

One way would be to use a nested query:

SELECT count(*)
FROM (
   SELECT COUNT(Genre) AS count
   FROM movies
   GROUP BY ID
   HAVING (count = 4)
) AS x

The inner query gets all the movies that have exactly 4 genres, then outer query counts how many rows the inner query returned.

per your advice, i am using handle and runnables to switch/change the content of the TextView using a "timer". for some reason, when running, the app always skips the second step ("Step Two: fry egg"), and only show the last (third) step ("Step three: serve egg").

TextView t; 
private String sText;

private Handler mHandler = new Handler();

private Runnable mWaitRunnable = new Runnable() {
    public void run() {
        t.setText(sText);
    }
};

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);

    mMonster = BitmapFactory.decodeResource(getResources(),
            R.drawable.monster1);

    t=new TextView(this); 
    t=(TextView)findViewById(R.id.TextView01); 

    sText = "Step One: unpack egg";
    t.setText(sText);

    sText = "Step Two: fry egg";        
    mHandler.postDelayed(mWaitRunnable, 3000);

    sText = "Step three: serve egg";
    mHandler.postDelayed(mWaitRunnable, 4000);      
    ...
}

You can remove this by adding !important to your outline.

button{
 outline: none !important;
}

I had this same error too. In my case it was because we had an old-fashioned import statement in our TypeScript AngularJS project like this:

import { IAttributes, IScope } from "angular";

which was compiled to JavaScript like this:

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });

This was needed back in the old days because we then used IAttributes in the code and TypeScript wouldn't have known what to do with it otherwise. But after removing the import statement, and converting IAttributes to ng.IAttributes those two JavaScript lines disappeared - and so did the error message.

I'm surprised no one has mentioned Microsoft's ildasm. It may not be as pretty as ILSpy or Reflector, but it comes with Visual Studio so many developers already have it.

To run it (assuming VS 2013, should be similar for other versions):

1. Select Start > All Programs > Visual Studio 2013 > Visual Studio Tools.
2. Double-click on Developer Command Prompt for VS2013.
3. Run "ildasm" from the resulting command prompt.
4. In the tool, select File > Open and open your executable or DLL.

Now you can navigate the DLL structure. Double-click on class members to see the IL. Use File > Dump to export IL to a file.

On the formula menu just Select "Default Values for Nulls" then just add all the fields like the below:

{@Table.Field1} + {@Table.Field2} + {@Table.Field3} + {@Table.Field4} + {@Table.Field5}

After searching stackoverflow and the web a lot, I've got to conclution that the best way of doing it is like this:

- (BOOL)isEndDateIsSmallerThanCurrent:(NSDate *)checkEndDate
{
    NSDate* enddate = checkEndDate;
    NSDate* currentdate = [NSDate date];
    NSTimeInterval distanceBetweenDates = [enddate timeIntervalSinceDate:currentdate];
    double secondsInMinute = 60;
    NSInteger secondsBetweenDates = distanceBetweenDates / secondsInMinute;

    if (secondsBetweenDates == 0)
        return YES;
    else if (secondsBetweenDates < 0)
        return YES;
    else
        return NO;
}

You can change it to difference between hours also.

Enjoy!

Edit 1

If you want to compare date with format of dd/MM/yyyy only, you need to add below lines between NSDate* currentdate = [NSDate date]; && NSTimeInterval distance

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd/MM/yyyy"];
[dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]
                          autorelease]];

NSString *stringDate = [dateFormatter stringFromDate:[NSDate date]];

currentdate = [dateFormatter dateFromString:stringDate];

I find the setTimeout method easier to use if you want to cancel the timeout:

function myTimeoutFunction() {
   doStuff();
   if (stillrunning) {
      setTimeout(myTimeoutFunction, 1000);
   }
}

myTimeoutFunction();

Also, if something would go wrong in the function it will just stop repeating at the first time error, instead of repeating the error every second.

You can use an array and unpack it inside the select:

cols = ['_2','_4','_5']
df.select(*cols).show()

Probably the project you are running is not compatible (API version/Hardware requirements) with the emulator settings. Check in your build.gradle file if the targetSDK and minimumSdk version is lower or equal to the sdk version of your Emulator.

You should also uncheck Tools > Android > Enable ADB Integration

If your case is different then restart your Android Studio and run the emulator again.

For people wanting a server runnable from within NodeJS script:

You can use expressjs/serve-static which replaces connect.static (which is no longer available as of connect 3):

myapp.js:

var http = require('http');

var finalhandler = require('finalhandler');
var serveStatic = require('serve-static');

var serve = serveStatic("./");

var server = http.createServer(function(req, res) {
  var done = finalhandler(req, res);
  serve(req, res, done);
});

server.listen(8000);

and then from command line:

• $ npm install finalhandler serve-static
• $ node myapp.js

Instead of

css=#container

use

css=div.container:nth-of-type(1),css=div.container:nth-of-type(2)

@echo off 
    setlocal enableextensions disabledelayedexpansion

    set "search=%1"
    set "replace=%2"

    set "textFile=Input.txt"

    for /f "delims=" %%i in ('type "%textFile%" ^& break ^> "%textFile%" ') do (
        set "line=%%i"
        setlocal enabledelayedexpansion
        >>"%textFile%" echo(!line:%search%=%replace%!
        endlocal
    )

for /f will read all the data (generated by the type comamnd) before starting to process it. In the subprocess started to execute the type, we include a redirection overwritting the file (so it is emptied). Once the do clause starts to execute (the content of the file is in memory to be processed) the output is appended to the file.

e.currentTarget would always return the component onto which the event listener is added.

On the other hand, e.target can be the component itself or any direct child or grand child or grand-grand-child and so on who received the event. In other words, e.target returns the component which is on top in the Display List hierarchy and must be in the child hierarchy or the component itself.

One use can be when you have several Image in Canvas and you want to drag Images inside the component but Canvas. You can add a listener on Canvas and in that listener you can write the following code to make sure that Canvas wouldn't get dragged.

function dragImageOnly(e:MouseEvent):void
{
    if(e.target==e.currentTarget)
    {
        return;
     }
     else
     {
        Image(e.target).startDrag();
     }
}

The following code will set the media stream volume to max:

AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,
    audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC),
    AudioManager.FLAG_SHOW_UI);

If you really just want a random value from the available key range, use random.choice on the dictionary's values (converted to list form, if Python 3).

>>> from random import choice
>>> d = {1: 'a', 2: 'b', 3: 'c'}
>>>> choice(list(d.values()))

An easy way to do this is to map the variable and return each Character as a String:

let someText = "hello"

let array = someText.map({ String($0) }) // [String]

The output should be ["h", "e", "l", "l", "o"].

Random Number of Random Items from an Array

def random_items(array)
  array.sample(1 + rand(array.count))
end

Examples of possible results:

my_array = ["one", "two", "three"]
my_array.sample(1 + rand(my_array.count))

=> ["two", "three"]
=> ["one", "three", "two"]
=> ["two"]

It looks like the Django REST framework uses the HTTP accept header in a Request in order to automatically determine which renderer to use:

http://www.django-rest-framework.org/api-guide/renderers/

Using the HTTP accept header may provide an alternative source for your "if something".

When I want the UI to be able to update its display while waiting for a task to complete, I use a while-loop that tests IsAlive on the thread:

    Thread t = new Thread(() => someMethod(parameters));
    t.Start();
    while (t.IsAlive)
    {
        Thread.Sleep(500);
        Application.DoEvents();
    }

Just like said Ibam, engineStrict is now deprecated. But I've found this solution:

check-version.js:

import semver from 'semver';
import { engines } from './package';

const version = engines.node;
if (!semver.satisfies(process.version, version)) {
  console.log(`Required node version ${version} not satisfied with current version ${process.version}.`);
  process.exit(1);
}

package.json:

{
  "name": "my package",
  "engines": {
    "node": ">=50.9" // intentionally so big version number
  },
  "scripts": {
    "requirements-check": "babel-node check-version.js",
    "postinstall": "npm run requirements-check"
  }
}

.nvmrc

And one more thing. A dotfile '.nvmrc' can be used for requiring specific node version - https://github.com/creationix/nvm#nvmrc

But, it is only respected by npm scripts (and yarn scripts).

You git reset --hard your local branch to remove changes from working tree and index, and you git push --force your revised local branch to the remote. (other solution here, involving deleting the remote branch, and re-pushing it)

This SO answer illustrates the danger of such a command, especially if people depends on the remote history for their own local repos.
You need to be prepared to point out people to the RECOVERING FROM UPSTREAM REBASE section of the git rebase man page

With Git 2.23 (August 2019, nine years later), you would use the new command git switch.
That is: git switch -C mybranch origin/mybranch~n
(replace n by the number of commits to remove)

That will restore the index and working tree, like a git reset --hard would.
The documentation adds:

-C <new-branch>
--force-create <new-branch>

Similar to --create except that if <new-branch> already exists, it will be reset to <start-point>.
This is a convenient shortcut for:

$ git branch -f <new-branch>
$ git switch <new-branch>

try parsing a default value which can be returned by max if length of v none

We can simply use

async: false 

This will do your need.

You can init a Git directory in an directory containing other files. After that you can add files to the repository and commit there.

Create a project with some code:

$ mkdir my_project
$ cd my_project
$ echo "foobar" > some_file

Then, while inside the project's folder, do an initial commit:

$ git init
$ git add some_file
$ git commit -m "Initial commit"

Then for using Bitbucket or such you add a remote and push up:

$ git remote add some_name user@host:repo
$ git push some_name

You also might then want to configure tracking branches, etc. See git remote set-branches and related commands for that.

I got this problem as well using the drupal 7 Location module. Autofilling all empty locations resulted in this error. Executing one of the requests to the location api manually resulted in this error in the returned JSON:

"Browser API keys cannot have referer restrictions when used with this API."

Resolving the problem then was easy: create a new key without any restrictions and use it only for Geocoding.

Note for those new to google api keys: by restrictions they mean limiting requests using an api key to specific domains / subdomains. (eg. only request from http://yourdomain.com are allowed).

check the name of the database in a file where you established a connection.

Or, if you're using PrototypeJS

<script type="text/javascript>
  Event.observe( $('thelink'), 'click', function(event) {
      //do stuff

      Event.stop(event);
  }
</script>

<a href="#" id="thelink">This is the link</a>

:set runtimepath?

This lists the path of all plugins loaded when a file is opened with Vim.

I believe when you need this kinds of operations on your Redux state the spread operator is your friend and this principal applies for all children.

Let's pretend this is your state:

const state = {
    houses: {
        gryffindor: {
          points: 15
        },
        ravenclaw: {
          points: 18
        },
        hufflepuff: {
          points: 7
        },
        slytherin: {
          points: 5
        }
    }
}

And you want to add 3 points to Ravenclaw

const key = "ravenclaw";
  return {
    ...state, // copy state
    houses: {
      ...state.houses, // copy houses
      [key]: {  // update one specific house (using Computed Property syntax)
        ...state.houses[key],  // copy that specific house's properties
        points: state.houses[key].points + 3   // update its `points` property
      }
    }
  }

By using the spread operator you can update only the new state leaving everything else intact.

Example taken from this amazing article, you can find almost every possible option with great examples.

Just uninstall NPCAP and install wpcap. This will fix the issue.

I solved this problem using the split npm module. Pipe your stream into split, and it will "Break up a stream and reassemble it so that each line is a chunk".

Sample code:

var fs = require('fs')
  , split = require('split')
  ;

var stream = fs.createReadStream(filePath, {flags: 'r', encoding: 'utf-8'});
var lineStream = stream.pipe(split());
linestream.on('data', function(chunk) {
    var json = JSON.parse(chunk);           
    // ...
});

You should also make sure that the ports WAMP uses aren't already in use.

That can be done by typing the following command into the command prompt:

netstat –o

To start the process with parameters, you can use following code:

string filename = Path.Combine(cPath,"HHTCtrlp.exe");
var proc = System.Diagnostics.Process.Start(filename, cParams);

To kill/exit the program again, you can use following code:

proc.CloseMainWindow(); 
proc.Close();

Previous answer didn't work for me.

But this worked perfectly. Convert Data URI to File then append to FormData

Method names which are same as the class name are called constructors. Constructors do not have a return type. So correct as:

private Flow()
{
   X = x;
   Y = y;
}

Or rename the function as:

private void DoFlow()
{
   X = x;
   Y = y;
}

Though the whole code does not make any sense to me.

This is lighter weight than xrange (and the while loop) since it doesn't even need to create the int objects. It also works equally well in Python2 and Python3

from itertools import repeat
for i in repeat(None, 10):
    do_sth()

Sometimes this issue occurs, If you are creating a java file for the first time in your system. The Extension of your Java file gets saved as the text file.

e.g Example.java.txt (wrong extension)

You need to change the text file extension to java file.

It should be like:

Example.java (right extension)

In my case it was because of me used + as in other language but in PHP strings concatenation operator is ..

Iterate through the list and check if contains your string "How" and if it does then remove. You can use following code:

// need to construct a new ArrayList otherwise remove operation will not be supported
List<String> list = new ArrayList<String>(Arrays.asList(new String[] 
                                  {"How are you?", "How you doing?","Joe", "Mike"}));
System.out.println("List Before: " + list);
for (Iterator<String> it=list.iterator(); it.hasNext();) {
    if (!it.next().contains("How"))
        it.remove(); // NOTE: Iterator's remove method, not ArrayList's, is used.
}
System.out.println("List After: " + list);

OUTPUT:

List Before: [How are you?, How you doing?, Joe, Mike]
List After: [How are you?, How you doing?]

You can get the UserProfile path with just this:

Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);

That's not yet implemented according this Microsoft Connect link: Microsoft Connect

The best way to fix it I have looked for the code or trick how to center nav menu and found the real solutions it works for all browsers and for my friends ;)

Here is how I have done:

body {
    margin: 0;
    padding: 0;
}

div maincontainer {
    margin: 0 auto;
    width: ___px;
    text-align: center;
}

ul {
    margin: 0;
    padding: 0;
}

ul li {
    margin-left: auto;
    margin-right: auto;
}

and do not forget to set doctype html5

Why not just use NSMutableAttributedString?

let attributedString = NSMutableAttributedString(string: "Want to learn iOS? Just visit developer.apple.com!")
        attributedString.addAttribute(.link, value: "https://developer.apple.com", range: NSRange(location: 30, length: 50))

        myView.attributedText = attributedString

Anaconda comes with an uninstaller, which should have been installed in the Start menu.

By default Bootstrap javascript files are included just before the closing body tag

        <script src="vendors/jquery-1.9.1.min.js"></script>
        <script src="bootstrap/js/bootstrap.min.js"></script>
        <script src="vendors/easypiechart/jquery.easy-pie-chart.js"></script>
        <script src="assets/scripts.js"></script>
 </body>

I took these javascript files into the head section right before the body tag and I wrote a small function to call the modal popup:

    <script src="vendors/jquery-1.9.1.min.js"></script>
    <script src="bootstrap/js/bootstrap.min.js"></script>
    <script src="vendors/easypiechart/jquery.easy-pie-chart.js"></script>
    <script src="assets/scripts.js"></script>

 <script type="text/javascript">
    function openModal() {
        $('#myModal').modal('show');
    }
</script>
</head>
<body>

then I could call the modal popup from code-behind with the following:

protected void lbEdit_Click(object sender, EventArgs e) {   
      ScriptManager.RegisterStartupScript(this,this.GetType(),"Pop", "openModal();", true);
}

This seems to work:

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {  
   /* IE10+ specific styles go here */  
}

You could have your controller action take an object which would reflect the form input names and the default model binder will automatically create this object for you:

[HttpPost]
public ActionResult SubmitAction(SomeModel model)
{
    var value1 = model.SimpleProp1;
    var value2 = model.SimpleProp2;
    var value3 = model.ComplexProp1.SimpleProp1;
    ...

    ... return something ...
}

Another (obviously uglier) way is:

[HttpPost]
public ActionResult SubmitAction()
{
    var value1 = Request["SimpleProp1"];
    var value2 = Request["SimpleProp2"];
    var value3 = Request["ComplexProp1.SimpleProp1"];
    ...

    ... return something ...
}

For anyone who doesn't like none of the solutions posted above like me then you can simply implement a timer yourself and stop the request execution by throwing a runtime exception. Something like below:

                  try 
                 {
                     timer.schedule(new TimerTask() {
                       @Override
                       public void run() {
                         timer.cancel();
                       }
                     }, /* specify time of the requst */ 1000);
                 }
                 catch(Exception e)
                 {
                   throw new RuntimeException("the request is taking longer than usual");
                 }

How to install java packages:

Install desired java version / versions using official ubuntu packages, which are managed using alternatives:
sudo apt install -y openjdk-8-jdk
or/and other version: sudo apt install -y openjdk-11-jdk

Above answers are correct only when you have only one version for all software on your machine, and you can skip using update-alternatives. So one can quickly hardcode it in .bashrc or some other place:
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64
but it's not healthy, as later on you may change the version.

Correct way to set JAVA_HOME (and optionally JAVA_SDK, JAVA_JRE )

The correct way (and mandatory when you have more than one), is to detect what update-alternative is pointing to, and always use update-alternatives to switch active version.

Here are the suggestions for both: only specific unix account or for all accounts (machine level).

1. for a specific unix account only:

Use this if you don't have permissions to do it at machine level.

cat <<'EOF' >>~/.bashrc

export JAVA_HOME=$(update-alternatives --query java | grep Value | cut -d" " -f2 | sed 's!\(\/.*\)jre\(.*\)!\1!g')
export JDK_HOME=${JAVA_HOME}
export JRE_HOME=${JDK_HOME}/jre/

EOF

2. To do it at machine level, and for all bourne shells, you need 2 steps:

2.a

cat <<'EOF' | sudo tee /etc/profile.d/java_home_env.sh >/dev/null

export JAVA_HOME=$(update-alternatives --query java | grep Value | cut -d" " -f2 | sed 's!\(\/.*\)jre\(.*\)!\1!g')
export JDK_HOME=${JAVA_HOME}
export JRE_HOME=${JDK_HOME}/jre/

EOF

As your shell might not be set as interactive by default, you may want to do this also:
2.b

cat <<'EOF' | sudo tee -a /etc/bash.bashrc >/dev/null
if [ -d /etc/profile.d ]; then
  for i in /etc/profile.d/*.sh; do
    if [ -r $i ]; then
      . $i
    fi
  done
  unset i
fi
EOF

PS: There should be no need to update the $PATH, as update-alternatives takes care of the link to /usr/bin/.
More on: https://manpages.ubuntu.com/manpages/trusty/man8/update-alternatives.8.html

You can use the library I've written. It's very easy to use:

Add this dependency to your gradle file:

dependencies {
    compile 'com.github.danylovolokh:android-logger:1.0.2'
}

Initialize the library in the Application class:

File logsDirectory = AndroidLogger.getDefaultLogFilesDirectory(this);
    int logFileMaxSizeBytes = 2 * 1024 * 1024; // 2Mb
    try {
        AndroidLogger.initialize(
                this,
                logsDirectory,
                "Log_File_Name",
                logFileMaxSizeBytes,
                false
                );
    } catch (IOException e) {
        // Some error happened - most likely there is no free space on the system
    }

This is how you use the library:

AndroidLogger.v("TAG", "Verbose Message");

And this is how to retrieve the logs:

AndroidLogger.processPendingLogsStopAndGetLogFiles(new AndroidLogger.GetFilesCallback() {
        @Override
        public void onFiles(File[] logFiles) {
            // get everything you need from these files
            try {
                AndroidLogger.reinitAndroidLogger();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    });

Hope it helps.

You can access Globals entity from any point of your App via Angular dependency injection. If you want to output Globals.role value in some component's template, you should inject Globals through the component's constructor like any service:

// hello.component.ts
import { Component } from '@angular/core';
import { Globals } from './globals';

@Component({
  selector: 'hello',
  template: 'The global role is {{globals.role}}',
  providers: [ Globals ] // this depends on situation, see below
})

export class HelloComponent {
  constructor(public globals: Globals) {}
}

I provided Globals in the HelloComponent, but instead it could be provided in some HelloComponent's parent component or even in AppModule. It will not matter until your Globals has only static data that could not be changed (say, constants only). But if it's not true and for example different components/services might want to change that data, then the Globals must be a singleton. In that case it should be provided in the topmost level of the hierarchy where it is going to be used. Let's say this is AppModule:

import { Globals } from './globals'

@NgModule({
  // ... imports, declarations etc
  providers: [
    // ... other global providers
    Globals // so do not provide it into another components/services if you want it to be a singleton
  ]
})

Also, it's impossible to use var the way you did, it should be

// globals.ts
import { Injectable } from '@angular/core';

@Injectable()
export class Globals {
  role: string = 'test';
}

Update

At last, I created a simple demo on stackblitz, where single Globals is being shared between 3 components and one of them can change the value of Globals.role.

A known issue: https://github.com/angular/angular/issues/4902

Core reason: the .d.ts file implicitly included by TypeScript varies with the compile target, so one needs to have more ambient declarations when targeting es5 even if things are actually present in the runtimes (e.g. chrome). More on lib.d.ts

If you're on the Model Overview page you get a tab with the schema. If you rightclick on that tab you get an option to "edit schema". From there you can rename the schema by adding a new name, then click outside the field. This goes for MySQL Workbench 5.2.30 CE

Edit: On the model overview it's under Physical Schemata

Screenshot:

Try this

public int GetFirstDigit(int number) {
  if ( number < 10 ) {
    return number;
  }
  return GetFirstDigit ( (number - (number % 10)) / 10);
}

EDIT

Several people have requested the loop version

public static int GetFirstDigitLoop(int number)
{
    while (number >= 10)
    {
        number = (number - (number % 10)) / 10;
    }
    return number;
}

EDIT:

The info below is only applicable to VS2008 and the 3.5 framework. VS2010 has a new registry location. Further details can be found on MSDN: How to Add or Remove References in Visual Studio.

ORIGINAL

It should be listed in the .NET tab of the Add Reference dialog. Assemblies that appear there have paths in registry keys under:

HKLM\Software\Microsoft\.NETFramework\AssemblyFolders\

I have a key there named Microsoft .NET Framework 3.5 Reference Assemblies with a string value of:

C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\

Navigating there I can see the actual System.Web.Extensions dll.

EDIT:

I found my .NET 4.0 version in:

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Web.Extensions.dll

I'm running Win 7 64 bit, so if you're on a 32 bit OS drop the (x86).

try

   System.Diagnostics.EventLog appLog = new System.Diagnostics.EventLog();
   appLog.Source = "This Application's Name";
   appLog.WriteEntry("An entry to the Application event log.");

Are you committed to using the Inner join syntax?

If not you could use this alternative syntax:

SELECT * 
FROM Y,X
WHERE (X.QID=Y.QID) or (X.QUID is null and Y.QUID is null)

CREATE TABLE table_temp_list_objects AS
SELECT o.owner, o.object_name FROM sys.all_objects o WHERE o.object_type ='TABLE';

for me I was naming branch as

Rel4.6/bug/Some-short-description

all I had to do is when using

git push origin Relx.x/bug/Some-short-description

to write

git push origin relx.x/bug/Some-short-description

as I used to create branches using small letter r in rel.

so, what caused this issue?

when I listed .git/refs/heads content I found

drwxr-xr-x  4 eslam_khoga  staff   128B Sep 22 20:22 relx.x

but no Relx.x!

and inside it bug and inside bug my branch's name.

So, git try to create a dir with same name but different case letters

but system is not case sensitive.

That's what caused this issue!

Instead of doing this:

$(document).ready(function() { });

You should be doing this:

jQuery(document).ready(function($) {

    // your code goes here

});

This is because WordPress may use $ for something other than jQuery, in the future, or now, and so you need to load jQuery in a way that the $ can be used only in a jQuery document ready callback.

You can acheive this with CSS but you are not techinically changing the arrow itself.

In this example I am actually hiding the default arrow and displaying my own arrow instead.

You can use WebClient class to connect to the network driver using credentials. Include the below namespace:

using System.Net;

WebClient request = new WebClient();
request.Credentials = new NetworkCredential("domain\username", "password");
string[] theFolders = Directory.GetDirectories(@"\\computer\share");

If you want your function can validate boolean objects too, the most efficient solution must be:

function isBoolean(val) {
  return val === false || val === true || val instanceof Boolean;
}

(list.Count() + 9) / 10

Everything else here is either overkill or simply wrong (except for bestsss' answer, which is awesome). We do not want the overhead of a function call (Math.Truncate(), Math.Ceiling(), etc.) when simple math is enough.

OP's question generalizes (pigeonhole principle) to:

How many boxes do I need to store x objects if only y objects fit into each box?

The solution:

1. derives from the realization that the last box might be partially empty, and
2. is (x + y - 1) ÷ y using integer division.

You'll recall from 3^rd grade math that integer division is what we're doing when we say 5 ÷ 2 = 2.

Floating-point division is when we say 5 ÷ 2 = 2.5, but we don't want that here.

Many programming languages support integer division. In languages derived from C, you get it automatically when you divide int types (short, int, long, etc.). The remainder/fractional part of any division operation is simply dropped, thus:

5 / 2 == 2

Replacing our original question with x = 5 and y = 2 we have:

How many boxes do I need to store 5 objects if only 2 objects fit into each box?

The answer should now be obvious: 3 boxes -- the first two boxes hold two objects each and the last box holds one.

(x + y - 1) ÷ y =
(5 + 2 - 1) ÷ 2 =
6 ÷ 2 =
3

So for the original question, x = list.Count(), y = 10, which gives the solution using no additional function calls:

(list.Count() + 9) / 10

Here is a method that returns the image dimensions:

from PIL import Image
import os

def get_image_dimensions(imagefile):
    """
    Helper function that returns the image dimentions

    :param: imagefile str (path to image)
    :return dict (of the form: {width:<int>, height=<int>, size_bytes=<size_bytes>)
    """
    # Inline import for PIL because it is not a common library
    with Image.open(imagefile) as img:
        # Calculate the width and hight of an image
        width, height = img.size

    # calculat ethe size in bytes
    size_bytes = os.path.getsize(imagefile)

    return dict(width=width, height=height, size_bytes=size_bytes)

How about this approach (c#)?

private int dividedBy3(int n) {
        List<Object> a = new Object[n].ToList();
        List<Object> b = new List<object>();
        while (a.Count > 2) {
            a.RemoveRange(0, 3);
            b.Add(new Object());
        }
        return b.Count;
    }

Add reference Project->References Microsoft XML, 6.0 and you can use example code:

    Dim xml As String

    xml = "<root><person><name>Me </name> </person> <person> <name>No Name </name></person></root> "
    Dim oXml As MSXML2.DOMDocument60
    Set oXml = New MSXML2.DOMDocument60
    oXml.loadXML xml
    Dim oSeqNodes, oSeqNode As IXMLDOMNode

    Set oSeqNodes = oXml.selectNodes("//root/person")
    If oSeqNodes.length = 0 Then
       'show some message
    Else
        For Each oSeqNode In oSeqNodes
             Debug.Print oSeqNode.selectSingleNode("name").Text
        Next
    End If 

be careful with xml node //Root/Person is not same with //root/person, also selectSingleNode("Name").text is not same with selectSingleNode("name").text

s = "123123STRINGabcabc"

def find_between( s, first, last ):
    try:
        start = s.index( first ) + len( first )
        end = s.index( last, start )
        return s[start:end]
    except ValueError:
        return ""

def find_between_r( s, first, last ):
    try:
        start = s.rindex( first ) + len( first )
        end = s.rindex( last, start )
        return s[start:end]
    except ValueError:
        return ""


print find_between( s, "123", "abc" )
print find_between_r( s, "123", "abc" )

gives:

123STRING
STRINGabc

I thought it should be noted - depending on what behavior you need, you can mix index and rindex calls or go with one of the above versions (it's equivalent of regex (.*) and (.*?) groups).

I think you want $data[$category] = $question;

Or in case you want an array that maps categories to array of questions:

$data = array();
foreach($file_data as $value) {
    list($category, $question) = explode('|', $value, 2);

    if(!isset($data[$category])) {
        $data[$category] = array();
    }
    $data[$category][] = $question;
}
print_r($data);

Also, consider to use a repository manager such as Nexus and configure all your repositories there.

The accepted answer already gives the best solution using built in formatting methods in 2008.

It should be noted that the results returned is dependent on the language of the login however.

SET language Russian

SELECT replace(CONVERT(NVARCHAR, getdate(), 106), ' ', '/') 

Returns

06/???/2015

at the time of writing.

For people coming across this question on more recent versions of SQL Server a method that avoids this issue - and the need to REPLACE is

FORMAT(GETDATE(),'dd/MMM/yyyy', 'en-us')

On 2005+ it would be possible to write a CLR UDF that accepted a DateTime, Formatting Pattern and Culture to simulate the same.

Note that I have changed 0dp to 0.1dp.

EDIT: See Aleks G comment below for a cleaner version

It is common practice in C++. This is because in C++ you can't have same name for the member function and member variable, and getter functions are often named without "get" prefix.

class Person
{
   public:
      std::string name() const;

   private:
      std::string name; // This would lead to a compilation error.
      std::string m_name; // OK.
};

main.cpp:9:19: error: duplicate member 'name'
      std::string name;
                  ^
main.cpp:6:19: note: previous declaration is here
      std::string name() const;
                  ^
1 error generated.

"m_" states for the "member". Prefix "_" is also common.

You shouldn't use it in programming languages that solve this problem by using different conventions/grammar.

textbox.Focus();
textbox.SelectionStart = 0;
textbox.SelectionLength = textbox.Text.Length;

I have some points to contribute with John's answer as follows:

Abstract factory is a factory of factories!

With the "Factory Method" (because just "Factory" is ambiguous), you produce implementations (Lemon, Orange, etc.) of a particular interface -- say, IFruit. This Factory could be called CitricFruitFactory.

But now you want to create another kinds of fruit that the CitricFruitFactory is not able to create. Maybe the code of CitricFruitFactory wouldn't make sense if you create an Strawberry in it (strawberry is not a citric fruit!).

So you could create a new Factory called RedFruitFactory that produces Strawberry, Raspberry, etc.

Like John Feminella said: "With the Abstract Factory pattern, you produce implementations of a particular Factory interface -- e.g., IFruitFactory. Each of those knows how to create different kinds of fruit."

That implementatios of IFruitFactory are CitricFruitFactory and RedFruitFactory!

MSYS has not been updated a long time, MSYS2 is more active, you can download from MSYS2, it has both mingw and cygwin fork package.

To install the MinGW-w64 toolchain (Reference):

1. Open MSYS2 shell from start menu
2. Run pacman -Sy pacman to update the package database
3. Re-open the shell, run pacman -Syu to update the package database and core system packages
4. Re-open the shell, run pacman -Su to update the rest
5. Install compiler:
   • For 32-bit target, run pacman -S mingw-w64-i686-toolchain
   • For 64-bit target, run pacman -S mingw-w64-x86_64-toolchain
6. Select which package to install, default is all
7. You may also need make, run pacman -S make

Make use of *(B) instead of *B[0]. Here, *(B+i) implies B[i] and *(B) implies B[0], that is
*(B+0)=*(B)=B[0].

#include <stdio.h>

int func(int *B){
    *B = 5;     
    // if you want to modify ith index element in the array just do *(B+i)=<value>
}

int main(void){

    int B[10] = {};
    printf("b[0] = %d\n\n", B[0]);
    func(B);
    printf("b[0] = %d\n\n", B[0]);
    return 0;
}

I modified my response to include the code for a test app I did.

Update: I have updated the jQuery to set the 'traditional' setting to true so this will work again (per @DustinDavis' answer).

First the javascript:

function test()
{
    var stringArray = new Array();
    stringArray[0] = "item1";
    stringArray[1] = "item2";
    stringArray[2] = "item3";
    var postData = { values: stringArray };

    $.ajax({
        type: "POST",
        url: "/Home/SaveList",
        data: postData,
        success: function(data){
            alert(data.Result);
        },
        dataType: "json",
        traditional: true
    });
}

And here's the code in my controller class:

public JsonResult SaveList(List<String> values)
{
    return Json(new { Result = String.Format("Fist item in list: '{0}'", values[0]) });
}

When I call that javascript function, I get an alert saying "First item in list: 'item1'". Hope this helps!

In case, for whatever reason, you are doing a rebase from a folder that's being sync'd by a cloud service (dropbox, drive, onedrive, etc), you should pause or turn off syncing as it will interfere with permissions during the rebase.

My (simply) code (three months studying Python):

def more_frequent_item(lst):
    new_lst = []
    times = 0
    for item in lst:
        count_num = lst.count(item)
        new_lst.append(count_num)
        times = max(new_lst)
    key = max(lst, key=lst.count)
    print("In the list: ")
    print(lst)
    print("The most frequent item is " + str(key) + ". Appears " + str(times) + " times in this list.")


more_frequent_item([1, 2, 45, 55, 5, 4, 4, 4, 4, 4, 4, 5456, 56, 6, 7, 67])

The output will be:

In the list: 
[1, 2, 45, 55, 5, 4, 4, 4, 4, 4, 4, 5456, 56, 6, 7, 67]
The most frequent item is 4. Appears 6 times in this list.

If you don't want the System.Web dependency, just paste this source code from HttpUtility class.

I just whipped this together from the source code of Mono. It contains the HttpUtility and all it's dependencies (like IHtmlString, Helpers, HttpEncoder, HttpQSCollection).

Then use HttpUtility.ParseQueryString.

Indeed, you can leave it empty (W3 validator doesn't complain).

Taking the idea one step further: leave out the ="". The advantage of this is that the link isn't treated as an anchor to the current page.

<a href>sth</a>

To get the user email, you have to log in the user with his Facebook account using the email permission. Use for that the Facebook PHP SDK (see on github) as following.

First check if the user is already logged in :

require "facebook.php";
$facebook = new Facebook(array(
    'appId'  => YOUR_APP_ID,
    'secret' => YOUR_APP_SECRET,
));

$user = $facebook->getUser();
if ($user) {
    try {
        $user_profile = $facebook->api('/me');
    } catch (FacebookApiException $e) {
        $user = null;
    }
}

If he his not, you can display the login link asking for the email permission :

if (!$user) {
    $args = array('scope' => 'email');
    echo '<a href="' . $facebook->getLoginUrl() . '">Login with Facebook</a>';
} else {
    echo '<a href="' . $facebook->getLogoutUrl() . '">Logout</a>';
}

When he is logged in the email can be found in the $user_profile array.

Hope that helps !

You can do either…

$qb->where('e.fecha BETWEEN :monday AND :sunday')
   ->setParameter('monday', $monday->format('Y-m-d'))
   ->setParameter('sunday', $sunday->format('Y-m-d'));

or…

$qb->where('e.fecha > :monday')
   ->andWhere('e.fecha < :sunday')
   ->setParameter('monday', $monday->format('Y-m-d'))
   ->setParameter('sunday', $sunday->format('Y-m-d'));

.NET 4.0+ has a generic Enum.TryParse

ContentEnum content;
Enum.TryParse(fileContentMessage, out content);

To include native libraries you need:

1. create "jar" file with special structure containing ".so" files;
2. include that file in dependencies list.

To create jar file, use the following snippet:

task nativeLibsToJar(type: Zip, description: 'create a jar archive of the native libs') {
    destinationDir file("$buildDir/native-libs")
    baseName 'native-libs'
    extension 'jar'
    from fileTree(dir: 'libs', include: '**/*.so')
    into 'lib/'
}

tasks.withType(Compile) {
    compileTask -> compileTask.dependsOn(nativeLibsToJar)
}

To include resulting file, paste the following line into "dependencies" section in "build.gradle" file:

compile fileTree(dir: "$buildDir/native-libs", include: 'native-libs.jar')

Generally, I agree with @kgrittn's advice. Go for it.

But to address your basic question about concat(): The new function concat() is useful if you need to deal with null values - and null has neither been ruled out in your question nor in the one you refer to.

If you can rule out null values, the good old (SQL standard) concatenation operator || is still the best choice, and @luis' answer is just fine:

SELECT col_a || col_b;

If either of your columns can be null, the result would be null in that case. You could defend with COALESCE:

SELECT COALESCE(col_a, '') || COALESCE(col_b, '');

But that get tedious quickly with more arguments. That's where concat() comes in, which never returns null, not even if all arguments are null. Per documentation:

NULL arguments are ignored.

SELECT concat(col_a, col_b);

The remaining corner case for both alternatives is where all input columns are null in which case we still get an empty string '', but one might want null instead (at least I would). One possible way:

SELECT CASE
          WHEN col_a IS NULL THEN col_b
          WHEN col_b IS NULL THEN col_a
          ELSE col_a || col_b
       END;

This gets more complex with more columns quickly. Again, use concat() but add a check for the special condition:

SELECT CASE WHEN (col_a, col_b) IS NULL THEN NULL
            ELSE concat(col_a, col_b) END;

How does this work?
(col_a, col_b) is shorthand notation for a row type expression ROW (col_a, col_b). And a row type is only null if all columns are null. Detailed explanation:

• NOT NULL constraint over a set of columns

Also, use concat_ws() to add separators between elements (ws for "with separator").

An expression like the one in Kevin's answer:

SELECT $1.zipcode || ' - ' || $1.city || ', ' || $1.state;

is tedious to prepare for null values in PostgreSQL 8.3 (without concat()). One way (of many):

SELECT COALESCE(
         CASE
            WHEN $1.zipcode IS NULL THEN $1.city
            WHEN $1.city    IS NULL THEN $1.zipcode
            ELSE $1.zipcode || ' - ' || $1.city
         END, '')
       || COALESCE(', ' || $1.state, '');

Function volatility is only STABLE

concat() and concat_ws() are STABLE functions, not IMMUTABLE because they can invoke datatype output functions (like timestamptz_out) that depend on locale settings.
Explanation by Tom Lane.

This prohibits their direct use in index expressions. If you know that the result is actually immutable in your case, you can work around this with an IMMUTABLE function wrapper. Example here:

• Does PostgreSQL support "accent insensitive" collations?

I guess you could write your own doclet or taglet to support this behaviour.

You can also do this (in python) by using re.split, and splitting based on your regular expression, thus returning all the parts that don't match the regex, splitting based on what doesn't match a regularexpression

<div data-bind="bindHTML: htmlValue"></div>

OR

<!-- ko bindHTML: htmlValue --><!-- /ko -->

?+?+?/?/?/? will let you navigate split panes in the direction of the arrow, i.e. when using ?+D to split panes vertically, ?+?+? and ?+?+? will let you switch between the panes.

To build on Sam Stern's answer, there is also a 3rd option which made things easier for me and that is using what Google call a Map, which is essentially a dictionary.

I think a dictionary is far better for the use case you're describing. I usually use arrays for stuff that isn't really updated too much, so they are more or less static. But for stuff that gets written a lot, specifically values that need to be updated for fields that are linked to something else in the database, dictionaries prove to be much easier to maintain and work with.

So for your specific case, the DB structure would look like this:

proprietary: "John Doe"
sharedWith:{
  whoEmail1: {when: timestamp},
  whoEmail2: {when: timestamp}
}

This will allow you to do the following:

var whoEmail = '[email protected]';

var sharedObject = {};
sharedObject['sharedWith.' + whoEmail + '.when'] = new Date();
sharedObject['merge'] = true;

firebase.firestore()
.collection('proprietary')
.doc(docID)
.update(sharedObject);

The reason for defining the object as a variable is that using 'sharedWith.' + whoEmail + '.when' directly in the set method will result in an error, at least when using it in a Node.js cloud function.

if you want to check for methods explicitly you can use the method.toSource() or method.toString() methods.

Typeface.js JavaScript Way:

With typeface.js you can embed custom fonts in your web pages so you don't have to render text to images

Instead of creating images or using flash just to show your site's graphic text in the font you want, you can use typeface.js and write in plain HTML and CSS, just as if your visitors had the font installed locally.

Both will generate the same columns when you run the migration. In rails console, you can see that this is the case:

:001 > Micropost
=> Micropost(id: integer, user_id: integer, created_at: datetime, updated_at: datetime)

The second command adds a belongs_to :user relationship in your Micropost model whereas the first does not. When this relationship is specified, ActiveRecord will assume that the foreign key is kept in the user_id column and it will use a model named User to instantiate the specific user.

The second command also adds an index on the new user_id column.

It turns out the compiler version I was using did not match the compiled version done with the coreset.o.

One was 32bit the other was 64bit. I'll leave this up in case anyone else runs into a similar problem.

I made this method based on a comment from Tony Lâmpada's answer. It works very well.

def scroll_to(element)
  page.execute_script("window.scrollTo(#{element.native.location.x}, #{element.native.location.y})")
end

To download ISIN code data the only place I see this is on the ISIN organizations website, www.isin.org. try http://isin.org, they should have a function where you can easily download.

What you are asking is thoroughly covered by Eric Lippert in his blog post Closing over the loop variable considered harmful and its sequel.

For me, the most convincing argument is that having new variable in each iteration would be inconsistent with for(;;) style loop. Would you expect to have a new int i in each iteration of for (int i = 0; i < 10; i++)?

The most common problem with this behavior is making a closure over iteration variable and it has an easy workaround:

foreach (var s in strings)
{
    var s_for_closure = s;
    query = query.Where(i => i.Prop == s_for_closure); // access to modified closure

My blog post about this issue: Closure over foreach variable in C#.

Whenever possible, you should avoid parsing the output of ls (see Greg's wiki on the subject). Basically, the output of ls will be ambiguous if there are funny characters in any of the filenames. It's also usually a waste of time. In this case, when you execute ls -d */, what happens is that the shell expands */ to a list of subdirectories (which is already exactly what you want), passes that list as arguments to ls -d, which looks at each one, says "yep, that's a directory all right" and prints it (in an inconsistent and sometimes ambiguous format). The ls command isn't doing anything useful!

Well, ok, it is doing one thing that's useful: if there are no subdirectories, */ will get left as is, ls will look for a subdirectory named "*", not find it, print an error message that it doesn't exist (to stderr), and not print the "*/" (to stdout).

The cleaner way to make an array of subdirectory names is to use the glob (*/) without passing it to ls. But in order to avoid putting "*/" in the array if there are no actual subdirectories, you should set nullglob first (again, see Greg's wiki):

shopt -s nullglob
array=(*/)
shopt -u nullglob # Turn off nullglob to make sure it doesn't interfere with anything later
echo "${array[@]}"  # Note double-quotes to avoid extra parsing of funny characters in filenames

If you want to print an error message if there are no subdirectories, you're better off doing it yourself:

if (( ${#array[@]} == 0 )); then
    echo "No subdirectories found" >&2
fi

Using Jest, you can do it like this:

test('it calls start logout on button click', () => {
    const mockLogout = jest.fn();
    const wrapper = shallow(<Component startLogout={mockLogout}/>);
    wrapper.find('button').at(0).simulate('click');
    expect(mockLogout).toHaveBeenCalled();
});

i had the same problem.I had to rewrite "DBContext" after adding reference to entityframework and it resolved the problem.
its means that Visual studio was not able to recognize the class automatically and waited for it to be re-typed. so its best to add reference first and then implement code. VS 2013 - ultimate used

Here is another way not depending on a library but using a regex.

You can use this single line:

text.matches("\\A\\p{ASCII}*\\z")

Whole example program:

public class Main {
    public static void main(String[] args) {
        char nonAscii = 0x00FF;
        String asciiText = "Hello";
        String nonAsciiText = "Buy: " + nonAscii;
        System.out.println(asciiText.matches("\\A\\p{ASCII}*\\z"));
        System.out.println(nonAsciiText.matches("\\A\\p{ASCII}*\\z"));
    }
}

Regarding the original code - it appears you want to share data between scopes. To share either Data or State between $scope the docs suggest using a service:

• To run stateless or stateful code shared across controllers — Use angular services instead.
• To instantiate or manage the life-cycle of other components (for example, to create service instances).

Ref: Angular Docs link here

Found these docu on the google docu pages:

• row --- int --- top row of the range
• column --- int--- leftmost column of the range
• optNumRows --- int --- number of rows in the range.
• optNumColumns --- int --- number of columns in the range

In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns

edit

Using the example on the docu:

// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);

The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G

So you come to the range: C2:G8

1. Create a new JPanel form
2. Add your desired components and code to it

YourJPanelForm stuff = new YourJPanelForm();
JOptionPane.showMessageDialog(null,stuff,"Your title here bro",JOptionPane.PLAIN_MESSAGE);

Your modal dialog awaits...

Even though it's stated in many of the other answers here, the component should either:

• implement shouldComponentUpdate to render only when state or properties change

• switch to extending a PureComponent, which already implements a shouldComponentUpdate method internally for shallow comparisons.

Here's an example that uses shouldComponentUpdate, which works only for this simple use case and demonstration purposes. When this is used, the component no longer re-renders itself on each click, and is rendered when first displayed, and after it's been clicked once.

Below method will check the post code and provide complete info

const valid_postcode = postcode => {
    try {
        postcode = postcode.replace(/\s/g, "");
        const fromat = postcode
            .toUpperCase()
            .match(/^([A-Z]{1,2}\d{1,2}[A-Z]?)\s*(\d[A-Z]{2})$/);
        const finalValue = `${fromat[1]} ${fromat[2]}`;
        const regex = /^([Gg][Ii][Rr] 0[Aa]{2})|((([A-Za-z][0-9]{1,2})|(([A-Za-z][A-Ha-hJ-Yj-y][0-9]{1,2})|(([AZa-z][0-9][A-Za-z])|([A-Za-z][A-Ha-hJ-Yj-y][0-9]?[A-Za-z]))))[0-9][A-Za-z]{2})$/i;
        return {
            isValid: regex.test(postcode),
            formatedPostCode: finalValue,
            error: false,
            info: 'It is a valid postcode'
        };
    } catch (error) {
        return { error: true , info: 'Invalid post code has been entered!'};
    }
};

valid_postcode('GU348RR')
result => {isValid: true, formatedPostCode: "GU34 8RR", error: false, info: "It is a valid postcode"}

valid_postcode('sdasd4746asd')
result => {error: true, info: "Invalid post code has been entered!"}

valid_postcode('787898523')
result => {error: true, info: "Invalid post code has been entered!"}

How is it not compatible with C#? Boolean.Parse and Boolean.TryParse is case insensitive and the parsing is done by comparing the value to Boolean.TrueString or Boolean.FalseString which are "True" and "False".

EDIT: When looking at the Boolean.ToString method in reflector it turns out that the strings are hard coded so the ToString method is as follows:

public override string ToString()
{
    if (!this)
    {
        return "False";
    }
    return "True";
}

Try with below command, and it will ask all values to INT

select case when isnumeric(YourColumn + '.0e0') = 1 then cast(YourColumn as int) else NULL end /* case */ from YourTable

Conaider this situation:

Mark and Lisa are secretly a couple, and because of age difference they are not allowed to be together. Mark and Lisa meet every night when nobody is watching. They have estabilished their own set of rules how to comunicate when the time comes. He stands in her garden and throws the small rock at her window. Lisa knows that it is time, and responds by waving from the window and opening it afterwards so Mark can climb in. That was example how the API works. The rock is initial request to another end. Another end waves, opens the window which basicaly means "Welcome in!".

API is almost like human language but for computers.

You can fake it like this:

-- with column headings 
select column1, column2 from some_table;

-- without column headings
select column1 as '', column2 as '' from some_table;

The only way I know of is to concatenate multiple lines with plus signs

With ES6+ you can just do [${variable}]

I have created a javascript function that looks if he has enough space on the right side. If it has he will show it on the right side, else he will display it on the left side. Again if it has has enough space on the right side, it will show right side. it is a loop...

$(document).ready(function () {

$('body, html').css('overflow', 'hidden');
var screenWidth = $(window).width();
$('body, html').css('overflow', 'visible');

if (screenWidth > 767) {

    $(".dropdown-submenu").hover(function () {

        var dropdownPosition = $(this).offset().left + $(this).width() + $(this).find('ul').width();
        var newPosition = $(this).offset().left - $(this).find('ul').width();
        var windowPosition = $(window).width();

        var oldPosition = $(this).offset().left + $(this).width();
        //document.title = dropdownPosition;
        if (dropdownPosition > windowPosition) {
            $(this).find('ul').offset({ "left": newPosition });
        } else {
            $(this).find('ul').offset({ "left": oldPosition });
        }
    });

}

});

One interesting approach is to cast CString to CStringA inside a string constructor. Unlike std::string s((LPCTSTR)cs); this will work even if _UNICODE is defined. However, if that is the case, this will perform conversion from Unicode to ANSI, so it is unsafe for higher Unicode values beyond the ASCII character set. Such conversion is subject to the _CSTRING_DISABLE_NARROW_WIDE_CONVERSION preprocessor definition. https://msdn.microsoft.com/en-us/library/5bzxfsea.aspx

        CString s1("SomeString");
        string s2((CStringA)s1);
