Here's a pure javascript version:

location.hash = '#123';

It'll scroll automatically. Remember to add the "#" prefix.

Yes, it's possible, the syntax is curl [protocol://]<host>[:port], for example:

curl example.com:1234

If you're using Bash, you can also use pseudo-device /dev files to open a TCP connection, e.g.:

exec 5<>/dev/tcp/127.0.0.1/1234
echo "send some stuff" >&5
cat <&5 # Receive some stuff.

^{See also: More on Using Bash's Built-in /dev/tcp File (TCP/IP).}

In python 3, we can use below method.

Read from file and convert to JSON

import json
from pprint import pprint

# Considering "json_list.json" is a json file

with open('json_list.json') as fd:
     json_data = json.load(fd)
     pprint(json_data)

with statement automatically close the opened file descriptor.

String to JSON

import json
from pprint import pprint

json_data = json.loads('{"name" : "myName", "age":24}')
pprint(json_data)

1. Force a method to get the struct (the constructor way).

   From this post:

   A good design is to make your type unexported, but provide an exported constructor function like NewMyType() in which you can properly initialize your struct / type. Also return an interface type and not a concrete type, and the interface should contain everything others want to do with your value. And your concrete type must implement that interface of course.

   This can be done by simply making the type itself unexported. You can export the function NewSomething and even the fields Text and DefaultText, but just don't export the struct type something.

2. Another way to customize it for you own module is by using a Config struct to set default values (Option 5 in the link). Not a good way though.

#!/usr/bin/env python
"""Print a field specified by row, column numbers from given csv file.

USAGE:
    %prog csv_filename row_number column_number
"""
import csv
import sys

filename = sys.argv[1]
row_number, column_number = [int(arg, 10)-1 for arg in sys.argv[2:])]

with open(filename, 'rb') as f:
     rows = list(csv.reader(f))
     print rows[row_number][column_number]

Example

$ python print-csv-field.py input.csv 2 2
ddddd

Note: list(csv.reader(f)) loads the whole file in memory. To avoid that you could use itertools:

import itertools
# ...
with open(filename, 'rb') as f:
     row = next(itertools.islice(csv.reader(f), row_number, row_number+1))
     print row[column_number]

Assuming that you added the Readme.md file through the interface provided by github, the readme is not yet in your local folder. Hence, when you try to push to the remote repo, you get an error, because your local repo is lacking the readme file - it's "behind the times", so to speak. Hence, as is suggested in the error message, try "git pull" first. This will pull the readme from the remote repository and merge it with your local directory. After that, you should have no problem pushing to the remote repo (the commands you posted look valid to me).

Retrieve an object using the tutorial shown in the Flask-SQLAlchemy documentation. Once you have the entity that you want to change, change the entity itself. Then, db.session.commit().

For example:

admin = User.query.filter_by(username='admin').first()
admin.email = '[email protected]'
db.session.commit()

user = User.query.get(5)
user.name = 'New Name'
db.session.commit()

Flask-SQLAlchemy is based on SQLAlchemy, so be sure to check out the SQLAlchemy Docs as well.

If on Python = 2.7:

# update different values in dictB
# I would assume only dictA should be updated,
# but the question specifies otherwise

for k in dictA.viewkeys() & dictB.viewkeys():
    if dictA[k] != dictB[k]:
        dictB[k]= dictA[k]

# add missing keys to dictA

dictA.update( (k,dictB[k]) for k in dictB.viewkeys() - dictA.viewkeys() )

You simply use the destroy() method to delete the specified widgets like this:

lbl = tk.Label(....)

btn = tk.Button(....., command=lambda: lbl.destroy())

Using this you can completely destroy the specific widgets.

I ran into a problem where the typical position: fixed and bottom: 0 didn't work. Discovered a neat functionality with position: sticky. Note it's "relatively" new so it won't with IE/Edge 15 and earlier.

A field which is declare with transient modifier it will not take part in serialized process. When an object is serialized(saved in any state), the values of its transient fields are ignored in the serial representation, while the field other than transient fields will take part in serialization process. That is the main purpose of the transient keyword.

You need to enable the option

Project Properties -> Build -> Packaging -> Build JAR after compiling

(but this is enabled by default)

Basically the thing that crops up 90% of the time is just analyzing loops. Do you have single, double, triple nested loops? The you have O(n), O(n^2), O(n^3) running time.

Very rarely (unless you are writing a platform with an extensive base library (like for instance, the .NET BCL, or C++'s STL) you will encounter anything that is more difficult than just looking at your loops (for statements, while, goto, etc...)

    <?php
if (isset($_POST['birthdate'])) {
    $timestamp = strtotime($_POST['birthdate']); 
    $date=date('d',$timestamp);
    $month=date('m',$timestamp);
    $year=date('Y',$timestamp);
}
?>  

The non-greedy ? works perfectly fine. It's just that you need to select dot matches all option in the regex engines (regexpal, the engine you used, also has this option) you are testing with. This is because, regex engines generally don't match line breaks when you use .. You need to tell them explicitly that you want to match line-breaks too with .

For example,

<img\s.*?>

works fine!

Check the results here.

Also, read about how dot behaves in various regex flavours.

A quick fix if using Android Studio (or Eclipse) is to disable the boot animation.

1) Select Run > Edit Configurations

2) Android Application > YOURAPP

3) Select the "Emulator" tab and check the "Disable boot animation"

This is will stop the "ANDROID" image from loading and boot directly to the lock screen, then keep your the emulator open. Also, to avoid problems, don't rotate the device before launch (Cmnd + Ctrl + F11), and don't try to run the app more than once during installation.

Make sure you specify pass header=None and add usecols=[3,6] for the 4th and 7th columns.

A pull request is just that: a request to merge one branch into another.

Your pull request doesn't "contain" anything, it's just a marker saying "please merge this branch into that one".

The set of changes the PR shows in the web UI is just the changes between the target branch and your feature branch. To modify your pull request, you must modify your feature branch, probably with a force push to the feature branch.

In your case, you'll probably want to amend your commit. Not sure about your exact situation, but some combination of interactive rebase and add -p should sort you out.

.row {
    margin-right: 15px;

Node.js uses the environmental variable NODE_PATH to allow for specifying additional directories to include in the module search path. You can use npm itself to tell you where global modules are stored with the npm root -g command. So putting those two together, you can make sure global modules are included in your search path with the following command (on Linux-ish)

export NODE_PATH=$(npm root --quiet -g)

here's a short paragraph from this article How to Make Frames (Main Windows) - The Java Tutorials - Oracle that explains what setBounds method does in addition to some other similar methods:

The pack method sizes the frame so that all its contents are at or above their preferred sizes. An alternative to pack is to establish a frame size explicitly by calling setSize or setBounds (which also sets the frame location). In general, using pack is preferable to calling setSize, since pack leaves the frame layout manager in charge of the frame size, and layout managers are good at adjusting to platform dependencies and other factors that affect component size.

the parameters of setBounds are (int x, int y, int width, int height) x and y are define the position/location and width and height define the size/dimension of the frame.

you should use Papercut this simple application to test send mail. and you don't need to configure anything.

Just run it and try test send mail:

<?php
$to = "[email protected]";
$subject = "My subject";
$txt = "Hello world!";
$headers = "From: [email protected]" . "\r\n" .
"CC: [email protected]";

mail($to,$subject,$txt,$headers);
?>

Cheer!

there is a really simple solution for this problem.

In the file fpdf.php go to the line that says:

if($txt!=='')
{

It is line 648 in my version of fpdf. Insert the following line of code:

$txt = iconv('utf-8', 'cp1252', $txt);

(above the line of code)

if($align=='R')

This works for all German special characters and should also work for Greek special characters. Otherwise simply replace cp1252 with the respective alphabet you require. You can see all supported characters here: http://en.wikipedia.org/wiki/Windows-1252

I saw the solution here: http://fudforum.org/forum/index.php?t=msg&goto=167345 Please use my example code above, as the original author forgot to insert a dash between utf and 8.

Hope the above was helpful.

The command setwd("~/") should set your working directory to your home directory. You might be experiencing problems because the OS you are using does not recognise "~/" as your home directory: this might be because of the OS, or it might be because of not having set that as your home directory elsewhere.

As you have tagged the post using RStudio:

• In the bottom right window move the tab over to 'files'.
• Navigate through there to whichever folder you were planning to use as your working directory.
• Under 'more' click 'set as working directory'

You will now have set the folder as your working directory. Use the command getwd() to get the working directory as it is now set, and save that as a variable string at the top of your script. Then use setwd with that string as the argument, so that each time you run the script you use the same directory.

For example at the top of my script I would have:

work_dir <- "C:/Users/john.smith/Documents"
setwd(work_dir)

Although deleting files manually works, there is an official way of removing dependencies of your project from your local (cache) repository and optionally re-resolving them from remote repositories.

The goal purge-local-repository, on the standard Maven dependency plugin, will remove the locally installed dependencies of this project from your cache. Optionally, you may re-resolve them from the remote repositories at the same time.

This should be used as part of a project phase because it applies to the dependencies for the containing project. Also transitive dependencies will be purged (locally) as well, by default.

If you want to explicitly remove a single artifact from the cache, use purge-local-repository with the manualInclude parameter. For example, from the command line:

mvn dependency:purge-local-repository -DmanualInclude="groupId:artifactId, ..."

The documentation implies that this does not remove transitive dependencies by default. If you are running with a non-standard cache location, or on multiple platforms, these are more reliable than deleting files "by hand".

The full documentation is in the maven-dependency-plugin spec.

Note: Older versions of the maven dependency plugin had a manual-purge-local-repository goal, which is now (version 2.8) implied by the use of manualInclude. The documentation for manualIncludes (with an s) should be read as well.

on your child page, put these:

<script type="text/javascript">
    function refreshAndClose() {
        window.opener.location.reload(true);
        window.close();
    }
</script>

and

<body onbeforeunload="refreshAndClose();">

but as a good UI design, you should use a Close button because it's more user friendly. see code below.

<script type="text/javascript">
    $(document).ready(function () {
        $('#btn').click(function () {
            window.opener.location.reload(true);
            window.close();
        });
    });
</script>

<input type='button' id='btn' value='Close' />

Just a note in case others have the same problem.

I had the same problem and found a different answer. I found that getting the height of a div that's height is determined by its contents needs to be initiated on window.load, or window.scroll not document.ready otherwise i get odd heights/smaller heights, i.e before the images have loaded. I also used outerHeight().

var currentHeight = 0;
$(window).load(function() {
    //get the natural page height -set it in variable above.

    currentHeight = $('#js_content_container').outerHeight();

    console.log("set current height on load = " + currentHeight)
    console.log("content height function (should be 374)  = " + contentHeight());   

});

It seems that the extension cannot be found anymore using "Visual Studio Team Services". Instead, by following the link in Using Visual Studio Code & Team Foundation Version Control on "Get the TFVC plugin working in Visual Studio Code" you get to the Azure Repos Extension for Visual Studio Code GitHub. There it is explained that you now have to look for "Team Azure Repos".

Also, please note, that with the new Settings editor in Visual Studio Code the additional slashes do not have to be added. The path to tf.exe for VS 2017 - if specified using the "user friendly" Settings editor - would be just

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

You can use GAS, which is gcc's backend assembler:

http://linux.die.net/man/1/as

You can use system:

system("/usr/local/bin/foo.sh");

This will block while executing it using sh -c, then return the status code.

CHANNEL_ID in NotificationChannel and Notification.Builder must be the same, try this code:

String CHANNEL_ID = "my_channel_01";
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, "Solveta Unread", NotificationManager.IMPORTANCE_DEFAULT);


Notification.Builder notification = new Notification.Builder(getApplicationContext(), CHANNEL_ID);

The code below is the combination of Chintan Panchal's answer along with Antoine Leclair's comment (placing the code in the windows resize event). (I didn't need the debounce mentioned by Antoine Leclair, however that could be a best practice.)

  $(window).resize( function() {
      $("#example").DataTable().columns.adjust().draw();
  });

This was the approach that worked in my case.

DatabaseMetaData dbm = con.getMetaData();
// check if "employee" table is there
ResultSet tables = dbm.getTables(null, null, "employee", null);
if (tables.next()) {
  // Table exists
}
else {
  // Table does not exist
}

What you have done is created a new anonymous function that takes a single parameter which then gets assigned to the local variable myMessage inside the function. Since no arguments are actually passed, and arguments which aren't passed a value become null, your function just does alert(null).

if(strcmp(aString, bString) == 0){
    //strings are the same
}

setState is asynchronous. You can see in this documentation by Reactjs

• https://reactjs.org/docs/faq-state.html#why-is-setstate-giving-me-the-wrong-valuejs
• https://reactjs.org/docs/faq-state.html#when-is-setstate-asynchronous

React intentionally “waits” until all components call setState() in their event handlers before starting to re-render. This boosts performance by avoiding unnecessary re-renders.

However, you might still be wondering why React doesn’t just update this.state immediately without re-rendering.

The reason is this would break the consistency between props and state, causing issues that are very hard to debug.

You can still perform functions if it is dependent on the change of the state value:

Option 1: Using callback function with setState

this.setState({
   value: newValue
},()=>{
   // It is an callback function.
   // Here you can access the update value
   console.log(this.state.value)
})

Option 2: using componentDidUpdate This function will be called whenever the state of that particular class changes.

componentDidUpdate(prevProps, prevState){
    //Here you can check if value of your desired variable is same or not.
    if(this.state.value !== prevState.value){
        // this part will execute if your desired variable updates
    }
}

For the MySql version 8.0.

Numeric Type Storage Requirements

Data Type       Storage Required
TINYINT         1 byte
SMALLINT        2 bytes
MEDIUMINT       3 bytes
INT, INTEGER    4 bytes
BIGINT          8 bytes
FLOAT(p)        4 bytes if 0 <= p <= 24, 8 bytes if 25 <= p <= 53
FLOAT           4 bytes
DOUBLE, REAL    8 bytes
DECIMAL(M,D), NUMERIC(M,D)  Varies; see following discussion
BIT(M)  approximately (M+7)/8 bytes

Values for DECIMAL (and NUMERIC) columns are represented using a binary format that packs nine decimal (base 10) digits into four bytes. Storage for the integer and fractional parts of each value are determined separately. Each multiple of nine digits requires four bytes, and the “leftover” digits require some fraction of four bytes. The storage required for excess digits is given by the following table.

Date and Time Type Storage Requirements For TIME, DATETIME, and TIMESTAMP columns, the storage required for tables created before MySQL 5.6.4 differs from tables created from 5.6.4 on. This is due to a change in 5.6.4 that permits these types to have a fractional part, which requires from 0 to 3 bytes.

Data Type   Storage Required Before MySQL 5.6.4   Storage Required as of MySQL 5.6.4
YEAR        1 byte                                1 byte
DATE        3 bytes                               3 bytes
TIME        3 bytes                               3 bytes + fractional seconds storage
DATETIME    8 bytes                               5 bytes + fractional seconds storage
TIMESTAMP   4 bytes                               4 bytes + fractional seconds storage

As of MySQL 5.6.4, storage for YEAR and DATE remains unchanged. However, TIME, DATETIME, and TIMESTAMP are represented differently. DATETIME is packed more efficiently, requiring 5 rather than 8 bytes for the nonfractional part, and all three parts have a fractional part that requires from 0 to 3 bytes, depending on the fractional seconds precision of stored values.

Fractional Seconds Precision    Storage Required
0                               0 bytes
1, 2                            1 byte
3, 4                            2 bytes
5, 6                            3 bytes

For example, TIME(0), TIME(2), TIME(4), and TIME(6) use 3, 4, 5, and 6 bytes, respectively. TIME and TIME(0) are equivalent and require the same storage.

For details about internal representation of temporal values, see MySQL Internals: Important Algorithms and Structures.

String Type Storage Requirements In the following table, M represents the declared column length in characters for nonbinary string types and bytes for binary string types. L represents the actual length in bytes of a given string value.

Data Type                    Storage Required
CHAR(M)                      The compact family of InnoDB row formats optimize storage for variable-length character sets. See COMPACT Row Format Characteristics. Otherwise, M × w bytes, <= M <= 255, where w is the number of bytes required for the maximum-length character in the character set.
BINARY(M)                    M bytes, 0 <= M <= 255
VARCHAR(M), VARBINARY(M)     L + 1 bytes if column values require 0 - 255 bytes, L + 2 bytes if values may require more than 255 bytes
TINYBLOB, TINYTEXT           L + 1 bytes, where L < 28
BLOB, TEXT                   L + 2 bytes, where L < 216
MEDIUMBLOB, MEDIUMTEXT       L + 3 bytes, where L < 224
LONGBLOB, LONGTEXT           L + 4 bytes, where L < 232
ENUM('value1','value2',...)  1 or 2 bytes, depending on the number of enumeration values (65,535 values maximum)
SET('value1','value2',...)   1, 2, 3, 4, or 8 bytes, depending on the number of set members (64 members maximum)

Use the CSS3 filter property:

img {
    -webkit-filter: grayscale(100%);
       -moz-filter: grayscale(100%);
         -o-filter: grayscale(100%);
        -ms-filter: grayscale(100%);
            filter: grayscale(100%); 
}

The browser support is a little bad but it's 100% CSS. A nice article about the CSS3 filter property you can find here: http://blog.nmsdvid.com/css-filter-property/

Actually you have selected Android from the tab change it to project.

Steps

Then you will found all folders.

Something like this should do:

function cleanLocalStorage() {
    for(key in localStorage) {
        delete localStorage[key];
    }
}

Be careful about using this, though, as the user may have other data stored in localStorage and would probably be pretty ticked if you deleted that. I'd recommend either a) not storing the user's data in localStorage or b) storing the user's account stuff in a single variable, and then clearing that instead of deleting all the keys in localStorage.

Edit: As Lyn pointed out, you'll be good with localStorage.clear(). My previous points still stand, however.

You are experiencing this issue for two reasons.

• The JPQL Query is not valid.
• You have not created an association between your entities that the underlying JPQL query can utilize.

When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)

User.java

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="iduser")
    private Long idUser;

    @Column(name="user_name")
    private String userName;

    @OneToOne()
    @JoinColumn(name="idarea")
    private Area area;

    public Long getIdUser() {
        return idUser;
    }

    public void setIdUser(Long idUser) {
        this.idUser = idUser;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public Area getArea() {
        return area;
    }

    public void setArea(Area area) {
        this.area = area;
    }
}

Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:

@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")

While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.

Area.java

@Entity
@Table(name = "area")
public class Area {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="idarea")
    private Long idArea;

    @Column(name="area_name")
    private String areaName;

    @OneToOne(fetch=FetchType.LAZY, mappedBy="area")
    private User user;

    public Long getIdArea() {
        return idArea;
    }

    public void setIdArea(Long idArea) {
        this.idArea = idArea;
    }

    public String getAreaName() {
        return areaName;
    }

    public void setAreaName(String areaName) {
        this.areaName = areaName;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
}

It's in fact almost the same in Python.. :-)

import datetime
year = datetime.date.today().year

Of course, date doesn't have a time associated, so if you care about that too, you can do the same with a complete datetime object:

import datetime
year = datetime.datetime.today().year

(Obviously no different, but you can store datetime.datetime.today() in a variable before you grab the year, of course).

One key thing to note is that the time components can differ between 32-bit and 64-bit pythons in some python versions (2.5.x tree I think). So you will find things like hour/min/sec on some 64-bit platforms, while you get hour/minute/second on 32-bit.

A very easy way to invoke return and non return value subroutines. is using Func and Action respectively. (see also https://msdn.microsoft.com/en-us/library/018hxwa8(v=vs.110).aspx)

Try this this example

using System;

public class Program
{
    private Func<string,string> FunctionPTR = null;  
    private Func<string,string, string> FunctionPTR1 = null;  
    private Action<object> ProcedurePTR = null; 



    private string Display(string message)  
    {  
        Console.WriteLine(message);  
        return null;  
    }  

    private string Display(string message1,string message2)  
    {  
        Console.WriteLine(message1);  
        Console.WriteLine(message2);  
        return null;  
    }  

    public void ObjectProcess(object param)
    {
        if (param == null)
        {
            throw new ArgumentNullException("Parameter is null or missing");
        }
        else 
        {
            Console.WriteLine("Object is valid");
        }
    }


    public void Main(string[] args)  
    {  
        FunctionPTR = Display;  
        FunctionPTR1= Display;  
        ProcedurePTR = ObjectProcess;
        FunctionPTR("Welcome to function pointer sample.");  
        FunctionPTR1("Welcome","This is function pointer sample");   
        ProcedurePTR(new object());
    }  
}

Expanding a bit on the other answers, here's a little example of how your command line scripts can get into trouble by incautious use of /usr/bin/env shebang lines:

$ /usr/local/bin/python -V
Python 2.6.4
$ /usr/bin/python -V
Python 2.5.1
$ cat my_script.py 
#!/usr/bin/env python
import json
print "hello, json"
$ PATH=/usr/local/bin:/usr/bin
$ ./my_script.py 
hello, json
$ PATH=/usr/bin:/usr/local/bin
$ ./my_script.py 
Traceback (most recent call last):
  File "./my_script.py", line 2, in <module>
    import json
ImportError: No module named json

The json module doesn't exist in Python 2.5.

One way to guard against that kind of problem is to use the versioned python command names that are typically installed with most Pythons:

$ cat my_script.py 
#!/usr/bin/env python2.6
import json
print "hello, json"

If you just need to distinguish between Python 2.x and Python 3.x, recent releases of Python 3 also provide a python3 name:

$ cat my_script.py 
#!/usr/bin/env python3
import json
print("hello, json")

width:200px;
white-space: nowrap;
text-overflow: ellipsis;
overflow: hidden;

Define width also to set overflow in one line

Sometimes (too often!) I have to untangle someone else's C++ code. And we all know that someone else's C++ code is a complete mess almost by definition :) So the first thing I do to decipher local data flow is put const in every variable definition until compiler starts barking. This means const-qualifying value arguments as well, because they are just fancy local variables initialized by caller.

Ah, I wish variables were const by default and mutable was required for non-const variables :)

using is used for importing namespaces not classes.

So if your class is in namespace X

namespace X
{
    public class MyClass {
         void stuff() {

         }
    }
}

then to use it in another namespace where you want it

using System;
using X;

public class MyMainClass {
    static void Main() {
        MyClass test = new MyClass();
    }
}

You could use a pre tag instead of a div. This would automatically display your \n's in the correct way.

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
         var display_txt = "1st line text" +"\n" + "2nd line text";
         $('#somediv').html(display_txt).css("color", "green");
});
</script>
</head>
<body>

<pre>
<p id="somediv"></p>
</pre>

</body>
</html>

My current choice is Razor. It is very clean and easy to read and keeps the view pages very easy to maintain. There is also intellisense support which is really great. ALos, when used with web helpers it is really powerful too.

To provide a simple sample:

@Model namespace.model
<!Doctype html>
<html>
<head>
<title>Test Razor</title>
</head>
<body>
<ul class="mainList">
@foreach(var x in ViewData.model)
{
<li>@x.PropertyName</li>
}
</ul>
</body>

And there you have it. That is very clean and easy to read. Granted, that's a simple example but even on complex pages and forms it is still very easy to read and understand.

As for the cons? Well so far (I'm new to this) when using some of the helpers for forms there is a lack of support for adding a CSS class reference which is a little annoying.

Thanks Nathj07

This my variant of the solution based on LINQ and the Descendants method of the XDocument class

using System;
using System.Linq;
using System.Xml.Linq;

class Test
{
    static void Main()
    {
        XDocument xml = XDocument.Parse(@"
        <root>
          <child id='1'/>
          <child id='2'>
            <subChild id='3'>
                <extChild id='5' />
                <extChild id='6' />
            </subChild>
            <subChild id='4'>
                <extChild id='7' />
            </subChild>
          </child>
        </root>");

        xml.Descendants().Where(p => p.Name.LocalName == "extChild")
                         .ToList()
                         .ForEach(e => Console.WriteLine(e));

        Console.ReadLine();
    }
}

Results:

For more details on the Desendants method take a look here.

Use parseJSON jquery method to covert string into object

var objData = jQuery.parseJSON(data);

Now you can write code

$('#result').html(objData .status +':' + objData .message);

If php_mcrypt installed on 64bit but reported missing by an installer, check the extension path:

vi /etc/php.d/mcrypt.ini

; Enable mcrypt extension module
;extension=module.so
extension=/usr/lib64/php/modules/mcrypt.so

It's not very clear what the problem is and what you are trying to accomplish from the code you posted, but I'll take a stab at it.

In general, I suggest calling a function on ng-click like so:

<a ng-click="navigateToPath()">click me</a>

obj.val1 & obj.val2 should be available on your controller's $scope, you dont need to pass those into a function from the markup.

then, in your controller:

$scope.navigateToPath = function(){
   var path = '/somePath/' + $scope.obj.val1 + '/' + $scope.obj.val2; //dont need the '#'
   $location.path(path)       
}

In latest Angular versions, min and max are already added. Here is the link: https://angular.io/api/forms/Validators#max

This is how I used Max validator in my project:

<mat-form-field class="globalInput">
          <input (change)="CalculateAmount()" matInput placeholder="Quantity" name="productQuantity" type="number" [formControl]="quantityFormControl">
        </mat-form-field>
        <mat-error *ngIf="quantityFormControl.hasError('max')">
          Only <strong>{{productQuantity}}</strong> available!
        </mat-error>

Initialize the form control and add the validator in the component:

  quantityFormControl = new FormControl('', Validators.max(15));

You can also set validator dynamically on an event like this:

  quantityFormControl = new FormControl();

OnProductSelected(){
    this.quantityFormControl.setValidators(Validators.max(this.someVariable));
  }

Hope it helps.

try this..

SELECT Name
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%CreatedDate%'

or you can generate a scripts of all procedures and search from there.

The MSDN documentation for C++'s GetTempFileName discusses your concern and answers it:

GetTempFileName is not able to guarantee that the file name is unique.

Only the lower 16 bits of the uUnique parameter are used. This limits GetTempFileName to a maximum of 65,535 unique file names if the lpPathName and lpPrefixString parameters remain the same.

Due to the algorithm used to generate file names, GetTempFileName can perform poorly when creating a large number of files with the same prefix. In such cases, it is recommended that you construct unique file names based on GUIDs.

1. Open Settings on Docker Desktop (Docker for Windows).
2. Select Shared Drives.
3. Select the drive that you want to use inside your containers (e.g., C).

4. Click Apply. You may be asked to provide user credentials.

5. The command below should now work on PowerShell (command prompt does not support ${PWD}):

   docker run --rm -v ${PWD}:/data alpine ls /data

IMPORTANT: if/when you change your Windows domain password, the mount will stop working silently, that is, -v will work but the container will not see your host folders and files. Solution: go back to Settings, uncheck the shared drives, Apply, check them again, Apply, and enter the new password when prompted.

In xaml

<TextBlock Text="{Binding CelsiusTemp}" />

In ViewModel, this way setting the value also works:

 public string CelsiusTemp
        {
            get { return string.Format("{0}°C", _CelsiusTemp); }
            set
            {
                value = value.Replace("°C", "");
              _CelsiusTemp = value;
            }
        }

You can use asdf to install and switch between multiple java versions. It has plugins for other languages as well. You can install asdf with Homebrew

brew install asdf

When asdf is configured, install java plugin

asdf plugin-add java

Pick a version to install

asdf list-all java

For example to install and configure adoptopenjdk8

asdf install java adoptopenjdk-8.0.272+10
asdf global java adoptopenjdk-8.0.272+10

And finally if needed, configure JAVA_HOME for your shell. Just add to your shell init script such as ~/.zshrc in case of zsh:

. ~/.asdf/plugins/java/set-java-home.zsh

xcopy /y /d  "$(ProjectDir)External\*.dll" "$(TargetDir)"

You can also refer to a relative path, the next example will find the DLL in a folder located one level above the project folder. If you have multiple projects that use the DLL in a single solution, this places the source of the DLL in a common area reachable when you set any of them as the Startup Project.

xcopy /y /d  "$(ProjectDir)..\External\*.dll" "$(TargetDir)"

The /y option copies without confirmation. The /d option checks to see if a file exists in the target and if it does only copies if the source has a newer timestamp than the target.

I found that in at least newer versions of Visual Studio, such as VS2109, $(ProjDir) is undefined and had to use $(ProjectDir) instead.

Leaving out a target folder in xcopy should default to the output directory. That is important to understand reason $(OutDir) alone is not helpful.

$(OutDir), at least in recent versions of Visual Studio, is defined as a relative path to the output folder, such as bin/x86/Debug. Using it alone as the target will create a new set of folders starting from the project output folder. Ex: … bin/x86/Debug/bin/x86/Debug.

Combining it with the project folder should get you to the proper place. Ex: $(ProjectDir)$(OutDir).

However $(TargetDir) will provide the output directory in one step.

To print to any printer on the network you can send a PJL/PCL print job directly to a network printer on port 9100.

Please have a look at the below link that should give a good start:

http://frank.zinepal.com/printing-directly-to-a-network-printer

Also, If there is a way to call Windows cmd you can use FTP put to print your page on 9100. Below link should give you details, I have used this method for HP printers but I believe it will work for other printers.

Pretty sure this solves what you're looking for:

HTML:

<table>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
</table>

Javascript (using jQuery):

$(document).ready(function(){
    $('.editbtn').click(function(){
        $(this).html($(this).html() == 'edit' ? 'modify' : 'edit');
    });
});

Edit:

Apparently I should have looked at your sample code first ;)

You need to change (at least) the ID attribute of each element. The ID is the unique identifier for each element on the page, meaning that if you have multiple items with the same ID, you'll get conflicts.

By using classes, you can apply the same logic to multiple elements without any conflicts.

JSFiddle sample

I was running on the same problem, wampmysqld64 did not start, so I checked the Mysql log which you should find it inside the main wamp64 folder, and I found all the details on why is not working. on my computer I found another mysql instance is running so it prevents the wampmysqld64 to start. I stopped the other instance, and everything works fine after.

Mine says:

Mozilla/5.0 (iPad; U; CPU OS 4_3 like Mac OS X; da-dk) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8F190 Safari/6533.18.5

Here's an example which helps to understand this:

public class Main {
    static abstract class A {
        abstract void foo();
        A() {
            System.out.println("Constructing A");
            foo();
        }
    }

    static class C extends A {
        C() { 
            System.out.println("Constructing C");
        }
        void foo() { 
            System.out.println("Using C"); 
        }
    }

    public static void main(String[] args) {
        C c = new C(); 
    }
}

If you run this code, you get the following output:

Constructing A
Using C
Constructing C

You see? foo() makes use of C before C's constructor has been run. If foo() requires C to have a defined state (i.e. the constructor has finished), then it will encounter an undefined state in C and things might break. And since you can't know in A what the overwritten foo() expects, you get a warning.

Example 2 on w3schools shows what you are trying to achieve.

<?php
header("Content-type:application/pdf");

// It will be called downloaded.pdf
header("Content-Disposition:attachment;filename='downloaded.pdf'");

// The PDF source is in original.pdf
readfile("original.pdf");
?>

Also remember that,

It is important to notice that header() must be called before any actual output is sent (In PHP 4 and later, you can use output buffering to solve this problem)

If one is on a Windows machine and in PowerShell, one needs to quote the argument such as:

git stash apply "stash@{0}"

...or to apply the changes and remove from the stash:

git stash pop "stash@{0}"

Otherwise without the quotes you might get this error:

fatal: ambiguous argument 'stash@': unknown revision or path not in the working tree.

import os
current_file = os.path.abspath(os.path.dirname(__file__))
parent_of_parent_dir = os.path.join(current_file, '../../')

Escape whitespace as well. It sounds to me like Firefox is assuming three arguments instead of one.   is the non-breaking space character. Even if it's not the whole problem, it may still be a good idea.

If you don't have Your own Data Class, then you can design your map as follows

Map<Integer, Object> map=new HashMap<Integer, Object>();

Here don't forget to use "instanceof" operator while retrieving the values from MAP.

If you have your own Data class then then you can design your map as follows

Map<Integer, YourClassName> map=new HashMap<Integer, YourClassName>();

    Demo d2= new Demo(2,"this",new Date(),2,1);
    Demo d3= new Demo(3,"is",new Date(),3,1);
    Demo d4= new Demo(4,"mytest",new Date(),4,1);
    //adding values to map
    map.put(d1.getKey(), d1);
    map.put(d2.getKey(), d2);
    map.put(d3.getKey(), d3);
    map.put(d4.getKey(), d4);
    //retrieving values from map
    Set<Integer> keySet= map.keySet();
    for(int i:keySet){
        System.out.println(map.get(i));
    }
    //searching key on map
    System.out.println(map.containsKey(d1.getKey()));
    //searching value on map
    System.out.println(map.containsValue(d1));
}

}

        this.key=key;
        this.message = message;
        this.time = time;
        this.count = count;
        this.version = version;
    }
    public String getMessage() {
        return message;
    }
    public Date getTime() {
        return time;

    public int getCount() {
        return count;

In my case I was developing an ASP.Net MVC5 web app and the certificate errors on my local dev machine (IISExpress certificate) started becoming a practical concern once I started working with service workers. Chrome simply wouldn't register my service worker because of the certificate error.

I did, however, notice that during my automated Selenium browser tests, Chrome seem to just "ignore" all these kinds of problems (e.g. the warning page about an insecure site), so I asked myself the question: How is Selenium starting Chrome for running its tests, and might it also solve the service worker problem?

Using Process Explorer on Windows, I was able to find out the command-line arguments with which Selenium is starting Chrome:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-logging --force-fieldtrials=SiteIsolationExtensions/Control --ignore-certificate-errors --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12207 --safebrowsing-disable-auto-update --test-type=webdriver --use-mock-keychain --user-data-dir="C:\Users\Sam\AppData\Local\Temp\some-non-existent-directory" data:,

There are a bunch of parameters here that I didn't end up doing necessity-testing for, but if I run Chrome this way, my service worker registers and works as expected.

The only one that does seem to make a difference is the --user-data-dir parameter, which to make things work can be set to a non-existent directory (things won't work if you don't provide the parameter).

Hope that helps someone else with a similar problem. I'm using Chrome 60.0.3112.90.

You can use the following with objects, unfortunately this does not work with strings though.

double? amount = (double?)someObject;

I use it for wrapping a session variable in a property (on a base page).. so my actual usage is (in my base page):

public int? OrganisationID
{
    get { return (int?)Session[Constants.Session_Key_OrganisationID]; }
    set { Session[Constants.Session_Key_OrganisationID] = value; }
}

I'm able to check for null in page logic:

if (base.OrganisationID == null)
    // do stuff

Multiple posted answer here, but probably this can help who is newly using PowerShell

SO if any space is there in your directory path do not forgot to add double inverted commas "".

[Ljava.lang.Object; is the name for Object[].class, the java.lang.Class representing the class of array of Object.

The naming scheme is documented in Class.getName():

If this class object represents a reference type that is not an array type then the binary name of the class is returned, as specified by the Java Language Specification (§13.1).

If this class object represents a primitive type or void, then the name returned is the Java language keyword corresponding to the primitive type or void.

If this class object represents a class of arrays, then the internal form of the name consists of the name of the element type preceded by one or more '[' characters representing the depth of the array nesting. The encoding of element type names is as follows:

Element Type        Encoding
boolean             Z
byte                B
char                C
double              D
float               F
int                 I
long                J
short               S 
class or interface  Lclassname;

Yours is the last on that list. Here are some examples:

// xxxxx varies
System.out.println(new int[0][0][7]); // [[[I@xxxxx
System.out.println(new String[4][2]); // [[Ljava.lang.String;@xxxxx
System.out.println(new boolean[256]); // [Z@xxxxx

The reason why the toString() method on arrays returns String in this format is because arrays do not @Override the method inherited from Object, which is specified as follows:

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

getClass().getName() + '@' + Integer.toHexString(hashCode())

Note: you can not rely on the toString() of any arbitrary object to follow the above specification, since they can (and usually do) @Override it to return something else. The more reliable way of inspecting the type of an arbitrary object is to invoke getClass() on it (a final method inherited from Object) and then reflecting on the returned Class object. Ideally, though, the API should've been designed such that reflection is not necessary (see Effective Java 2nd Edition, Item 53: Prefer interfaces to reflection).

On a more "useful" toString for arrays

java.util.Arrays provides toString overloads for primitive arrays and Object[]. There is also deepToString that you may want to use for nested arrays.

Here are some examples:

int[] nums = { 1, 2, 3 };

System.out.println(nums);
// [I@xxxxx

System.out.println(Arrays.toString(nums));
// [1, 2, 3]

int[][] table = {
        { 1, },
        { 2, 3, },
        { 4, 5, 6, },
};

System.out.println(Arrays.toString(table));
// [[I@xxxxx, [I@yyyyy, [I@zzzzz]

System.out.println(Arrays.deepToString(table));
// [[1], [2, 3], [4, 5, 6]]

There are also Arrays.equals and Arrays.deepEquals that perform array equality comparison by their elements, among many other array-related utility methods.

Here, add this line to .zshrc:

export PATH=/home/david/pear/bin:$PATH

EDIT: This does work, but ony's answer below is better, as it takes advantage of the structured interface ZSH provides for variables like $PATH. This approach is standard for bash, but as far as I know, there is no reason to use it when ZSH provides better alternatives.

The actual walk through the directories works as you have coded it. If you replace the contents of the inner loop with a simple print statement you can see that each file is found:

import os
rootdir = 'C:/Users/sid/Desktop/test'

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        print os.path.join(subdir, file)

If you still get errors when running the above, please provide the error message.

Updated for Python3

import os
rootdir = 'C:/Users/sid/Desktop/test'

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        print(os.path.join(subdir, file))

if [ "$var_remote" = "$var_local" ]; then
    echo "Strings are equal." #1
else
    echo "Strings are not equal." #0 if you want
fi

Then you did compare local git and remote git last commit number....

You can try converting your image from tiff to PNG, here is how to do it:

import com.sun.media.jai.codec.ImageCodec;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageEncoder;
import com.sun.media.jai.codec.PNGEncodeParam;
import com.sun.media.jai.codec.TIFFDecodeParam;
import java.awt.image.RenderedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import javaxt.io.Image;

public class ImgConvTiffToPng {

    public static byte[] convert(byte[] tiff) throws Exception {

        byte[] out = new byte[0];
        InputStream inputStream = new ByteArrayInputStream(tiff);

        TIFFDecodeParam param = null;

        ImageDecoder dec = ImageCodec.createImageDecoder("tiff", inputStream, param);
        RenderedImage op = dec.decodeAsRenderedImage(0);

        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

        PNGEncodeParam jpgparam = null;
        ImageEncoder en = ImageCodec.createImageEncoder("png", outputStream, jpgparam);
        en.encode(op);
        outputStream = (ByteArrayOutputStream) en.getOutputStream();
        out = outputStream.toByteArray();
        outputStream.flush();
        outputStream.close();

        return out;

    }

I just tried with PHP 5.2, and that constant seems to exists :

var_dump(PDO::MYSQL_ATTR_INIT_COMMAND);

Gives me :

int 1002

But it seems there is a bug in PHP 5.3, that causes this constant to not exists anymore -- or, at least, not when the mysqlnd driver is used (and it's the one that's configured by default)

I suppose a temporary solution, as suggested on this bug report, could be to directly use the integer 1002 value, instead of the contant...

But note that you should go back to using the constant as soon as possible -- as this makes the code easier to understand.

It works for me on github

I had the same problem and thus I wrote a script which searches all pdf files in the specified folder for a string and prints the PDF files wich matched the query string.

Maybe this will be helpful to you.

You can use cluster module. Check this.

var cluster = require('cluster');
var http = require('http');
var numCPUs = require('os').cpus().length;

if (cluster.isMaster) {
    // Fork workers.
    for (var i = 0; i < numCPUs; i++) {
        cluster.fork();
    }

    cluster.on('exit', function(worker, code, signal) {
        console.log('worker ' + worker.process.pid + ' died');
    });
} else {
    // Workers can share any TCP connection
    // In this case its a HTTP server
    http.createServer(function(req, res) {
        res.writeHead(200);
        res.end("hello world\n");
    }).listen(8000);
}

I know there are already many answers, but I found this very helpful: http://tutorials.jenkov.com/dependency-injection/index.html

No Dependency:

public class MyDao {

  protected DataSource dataSource = new DataSourceImpl(
    "driver", "url", "user", "password");

  //data access methods...
  public Person readPerson(int primaryKey) {...}     
}

Dependency:

public class MyDao {

  protected DataSource dataSource = null;

  public MyDao(String driver, String url, String user, String password) {
    this.dataSource = new DataSourceImpl(driver, url, user, password);
  }

  //data access methods...
  public Person readPerson(int primaryKey) {...}
}

Notice how the DataSourceImpl instantiation is moved into a constructor. The constructor takes four parameters which are the four values needed by the DataSourceImpl. Though the MyDao class still depends on these four values, it no longer satisfies these dependencies itself. They are provided by whatever class creating a MyDao instance.

Best way is to Use a Python Web Frame Work you can choose Django/Flask. I will suggest you to Use Django because it's more powerful. Here is Step by guide to get complete your task :

pip install django
django-admin createproject buttonpython

then you have to create a file name views.py in buttonpython directory.

write below code in views.py:

from django.http import HttpResponse

def sample(request):
    #your python script code
    output=code output
    return HttpResponse(output)

Once done navigate to urls.py and add this stanza

from . import views

path('', include('blog.urls')),

Now go to parent directory and execute manage.py

python manage.py runserver 127.0.0.1:8001

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.

Option 1: Using Maven

If your project uses Maven you can simply include UCanAccess via the following coordinates:

groupId: net.sf.ucanaccess
artifactId: ucanaccess

The following is an excerpt from pom.xml, you may need to update the <version> to get the most recent release:

  <dependencies>
    <dependency>
        <groupId>net.sf.ucanaccess</groupId>
        <artifactId>ucanaccess</artifactId>
        <version>4.0.4</version>
    </dependency>
  </dependencies>

Option 2: Manually adding the JARs to your project

As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:

UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)

Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like

ucanaccess-4.0.1.jar  
  /lib/
    commons-lang-2.6.jar  
    commons-logging-1.1.1.jar  
    hsqldb.jar  
    jackcess-2.1.6.jar

All you need to do is add all five (5) JARs to your project.

NOTE: Do not add loader/ucanload.jar to your build path if you are adding the other five (5) JAR files. The UcanloadDriver class is only used in special circumstances and requires a different setup. See the related answer here for details.

Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path.... Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this

NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.

After adding all five (5) JAR files the "Libraries" folder should look something like this:

IntelliJ IDEA: Choose File > Project Structure... from the main menu. In the "Libraries" pane click the "Add" (+) button and add the five (5) JAR files. Once that is done the project should look something like this:

That's it!

Now "U Can Access" data in .accdb and .mdb files using code like this

// assumes...
//     import java.sql.*;
Connection conn=DriverManager.getConnection(
        "jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
    System.out.println(rs.getString(1));
}

Disclosure

At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.

Granted you have administrative Windows privileges on the server, another option would be to start SQL Server in Single User Mode, using the Startup parameter "-m". Doing this, you can login using SQLCMD, create a new user and give it sysadmin privileges. Finally, you have to disable Single User Mode, login to SSMS using your new user, and go to Segurity/Logins and change "sa" user password.

You can check this post: http://v-consult.be/2011/05/26/recover-sa-password-microsoft-sql-server-2008-r2/

org.eclipse.m2e.core.prefs file is in .settings folder. If you face the problem of

An internal error occurred during: "Updating Maven Project". java.lang.NullPointerException

Delete the project from eclipse then by deleting the .settings folder & .project file in the project -> then re-import the project.

As of PHP 7.1.0, negative string offsets are also supported. So, if you keep up with the times, you can access the last character in the string like this:

$str[-1]

DEMO

At the request of a @mickmackusa, I supplement my answer with possible ways of application:

<?php

$str='abcdef';
var_dump($str[-2]); // => string(1) "e"

$str[-3]='.';
var_dump($str);     // => string(6) "abc.ef"

var_dump(isset($str[-4]));  // => bool(true)

var_dump(isset($str[-10])); // => bool(false)

There is also another approach without the use of DomXPath or Zend_Dom_Query.

Based on dav's original function, I wrote the following function that returns all the children of the parent node whose tag and class match the parameters.

function getElementsByClass(&$parentNode, $tagName, $className) {
    $nodes=array();

    $childNodeList = $parentNode->getElementsByTagName($tagName);
    for ($i = 0; $i < $childNodeList->length; $i++) {
        $temp = $childNodeList->item($i);
        if (stripos($temp->getAttribute('class'), $className) !== false) {
            $nodes[]=$temp;
        }
    }

    return $nodes;
}

suppose you have a variable $html the following HTML:

<html>
 <body>
  <div id="content_node">
    <p class="a">I am in the content node.</p>
    <p class="a">I am in the content node.</p>
    <p class="a">I am in the content node.</p>    
  </div>
  <div id="footer_node">
    <p class="a">I am in the footer node.</p>
  </div>
 </body>
</html>

use of getElementsByClass is as simple as:

$dom = new DOMDocument('1.0', 'utf-8');
$dom->loadHTML($html);
$content_node=$dom->getElementById("content_node");

$div_a_class_nodes=getElementsByClass($content_node, 'div', 'a');//will contain the three nodes under "content_node".

This will limit it to however many lines you want it limited to and is responsive

An idea that nobody has suggested, doing it based on the height of the element and then stripping it back from there.

Fiddle - https://jsfiddle.net/hutber/u5mtLznf/ <- ES6 version

But basically you want to grab the line height of the element, loop through all the text and stop when its at a certain lines height:

'use strict';

var linesElement = 3; //it will truncate at 3 lines.
var truncateElement = document.getElementById('truncateme');
var truncateText = truncateElement.textContent;

var getLineHeight = function getLineHeight(element) {
  var lineHeight = window.getComputedStyle(truncateElement)['line-height'];
  if (lineHeight === 'normal') {
    // sucky chrome
    return 1.16 * parseFloat(window.getComputedStyle(truncateElement)['font-size']);
  } else {
    return parseFloat(lineHeight);
  }
};

linesElement.addEventListener('change', function () {
  truncateElement.innerHTML = truncateText;
  var truncateTextParts = truncateText.split(' ');
  var lineHeight = getLineHeight(truncateElement);
  var lines = parseInt(linesElement.value);

  while (lines * lineHeight < truncateElement.clientHeight) {
    console.log(truncateTextParts.length, lines * lineHeight, truncateElement.clientHeight);
    truncateTextParts.pop();
    truncateElement.innerHTML = truncateTextParts.join(' ') + '...';
  }
});

CSS

#truncateme {
   width: auto; This will be completely dynamic to the height of the element, its just restricted by how many lines you want it to clip to
}

Perhaps it behaves slightly different on Eclipselink. To re-attach detached objects without getting stale data, I usually do:

Object obj = em.find(obj.getClass(), id);

and as an optional a second step (to get caches invalidated):

em.refresh(obj)

Rails.application.routes.default_url_options[:host]= 'localhost:3000'

In the developemnt.rb / test.rb, can be more concise as following:

Rails.application.configure do
  # ... other config ...

  routes.default_url_options[:host] = 'localhost:3000'
end

It is Work for me:

language:{"infoEmpty": "No records available",}

You just need the $('button').prop('disabled', true); part, the button will automatically take the disabled class.

You can also use sed's change line to accomplish this:

sed -i "/aaa=/c\aaa=xxx" your_file_here

This will go through and find any lines that pass the aaa= test, which means that the line contains the letters aaa=. Then it replaces the entire line with aaa=xxx. You can add a ^ at the beginning of the test to make sure you only get the lines that start with aaa= but that's up to you.

create a file called spark-env.sh in spark/conf directory and add this line

SPARK_EXECUTOR_MEMORY=2000m #memory size which you want to allocate for the executor

Update: I wrote a solution that doesn't require reading the entire file in one go. It's too big for a stackoverflow answer, but can be found here jsonstream.

You can use json.JSONDecoder.raw_decode to decode arbitarily big strings of "stacked" JSON (so long as they can fit in memory). raw_decode stops once it has a valid object and returns the last position where wasn't part of the parsed object. It's not documented, but you can pass this position back to raw_decode and it start parsing again from that position. Unfortunately, the Python json module doesn't accept strings that have prefixing whitespace. So we need to search to find the first none-whitespace part of your document.

from json import JSONDecoder, JSONDecodeError
import re

NOT_WHITESPACE = re.compile(r'[^\s]')

def decode_stacked(document, pos=0, decoder=JSONDecoder()):
    while True:
        match = NOT_WHITESPACE.search(document, pos)
        if not match:
            return
        pos = match.start()
        
        try:
            obj, pos = decoder.raw_decode(document, pos)
        except JSONDecodeError:
            # do something sensible if there's some error
            raise
        yield obj

s = """

{"a": 1}  


   [
1
,   
2
]


"""

for obj in decode_stacked(s):
    print(obj)

prints:

{'a': 1}
[1, 2]

Start your script with the following line. The script will first run and then you will get the python command prompt. At this point all variables and functions will be available for interactive use and invocations.

#!/usr/bin/env python -i

1. Installing OpenCV 2.4.3

First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\.

Wait until all files get extracted. It will create a new directory C:\opencv which contains OpenCV header files, libraries, code samples, etc.

Now you need to add the directory C:\opencv\build\x86\vc10\bin to your system PATH. This directory contains OpenCV DLLs required for running your code.

Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...

On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin; (3), then click Ok.

On some computers, you may need to restart your computer for the system to recognize the environment path variables.

This will completes the OpenCV 2.4.3 installation on your computer.

2. Create a new project and set up Visual C++

Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest) and set the project location (e.g: c:\projects).

Click Ok. Visual C++ will create an empty project.

Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest and select Properties → VC++ Directories.

Select Include Directories to add a new entry and type C:\opencv\build\include.

Click Ok to close the dialog.

Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib.

Click Ok to close the dialog.

Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:

opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib

Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).

Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.

NOTE:

These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:

opencv_core243.lib
opencv_imgproc243.lib
...

instead of:

opencv_core243d.lib
opencv_imgproc243d.lib
...

You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.

Name your file (e.g: loadimg.cpp) and click Ok. Type the code below in the editor:

#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    Mat im = imread("c:/full/path/to/lena.jpg");
    if (im.empty()) 
    {
        cout << "Cannot load image!" << endl;
        return -1;
    }
    imshow("Image", im);
    waitKey(0);
}

The code above will load c:\full\path\to\lena.jpg and display the image. You can use any image you like, just make sure the path to the image is correct.

Type F5 to compile the code, and it will display the image in a nice window.

And that is your first OpenCV program!

3. Where to go from here?

Now that your OpenCV environment is ready, what's next?

1. Go to the samples dir → c:\opencv\samples\cpp.
2. Read and compile some code.
3. Write your own code.

You can use the tool APIC available here https://chrome.google.com/webstore/detail/apic-complete-api-solutio/ggnhohnkfcpcanfekomdkjffnfcjnjam. This tool allows you to test websocket which use either StompJS or native Websocket. More info here at www.apic.app

As the question is asked years ago, and Android is evolved a lot on this URI scheme.
From original URI scheme, to deep link, and now Android App Links.

Android now recommends to use HTTP URLs, not define your own URI scheme. Because Android App Links use HTTP URLs that link to a website domain you own, so no other app can use your links. You can check the comparison of deep link and Android App links from here

Now you can easily add a URI scheme by using Android Studio option: Tools > App Links Assistant. Please refer the detail to Android document: https://developer.android.com/studio/write/app-link-indexing.html

For me, the problem occurs when I've downloaded macOS Compressed Archive which underlying directory contains

jdk-11.0.8.jdk
- Contents
  - Home
    - bin
    - ...
  - MacOS
  - _CodeSignature

So, to solve the problem, JAVA_HOME should be pointed directly to /Path-to-JDK/Contents/Home.

The docs mention train_test_split is just a convenience function on top of shuffle split.

I just rearranged some of their code to make my own example. Note the actual solution is the middle block of code. The rest is imports, and setup for a runnable example.

from sklearn.model_selection import ShuffleSplit
from sklearn.utils import safe_indexing, indexable
from itertools import chain
import numpy as np
X = np.reshape(np.random.randn(20),(10,2)) # 10 training examples
y = np.random.randint(2, size=10) # 10 labels
seed = 1

cv = ShuffleSplit(random_state=seed, test_size=0.25)
arrays = indexable(X, y)
train, test = next(cv.split(X=X))
iterator = list(chain.from_iterable((
    safe_indexing(a, train),
    safe_indexing(a, test),
    train,
    test
    ) for a in arrays)
)
X_train, X_test, train_is, test_is, y_train, y_test, _, _  = iterator

print(X)
print(train_is)
print(X_train)

Now I have the actual indexes: train_is, test_is

When you don’t define any constructor in your class, compiler defines default one for you, however when you declare any constructor (in your example you have already defined a parameterized constructor), compiler doesn’t do it for you.

Since you have defined a constructor in class code, compiler didn’t create default one. While creating object you are invoking default one, which doesn’t exist in class code. Then the code gives an compilation error.

squares = squarer(x)

Arithmetic operations on arrays are automatically applied elementwise, with efficient C-level loops that avoid all the interpreter overhead that would apply to a Python-level loop or comprehension.

Most of the functions you'd want to apply to a NumPy array elementwise will just work, though some may need changes. For example, if doesn't work elementwise. You'd want to convert those to use constructs like numpy.where:

def using_if(x):
    if x < 5:
        return x
    else:
        return x**2

becomes

def using_where(x):
    return numpy.where(x < 5, x, x**2)

I was using xmlToJson just to get a single value of the xml.
I found doing the following is much easier (if the xml only occurs once..)

let xml =_x000D_
'<person>' +_x000D_
  ' <id>762384324</id>' +_x000D_
  ' <firstname>Hank</firstname> ' +_x000D_
  ' <lastname>Stone</lastname>' +_x000D_
'</person>';_x000D_
_x000D_
let getXmlValue = function(str, key) {_x000D_
  return str.substring(_x000D_
    str.lastIndexOf('<' + key + '>') + ('<' + key + '>').length,_x000D_
    str.lastIndexOf('</' + key + '>')_x000D_
  );_x000D_
}_x000D_
_x000D_
_x000D_
alert(getXmlValue(xml, 'firstname')); // gives back Hank

all answers are great but I just want to give you a good example

select replace('this value from table', 'table',  'table but updated')

this SQL statement will replace the existence of the word "table" (second parameter) inside the given statement(first parameter) with the third parameter

the initial value is this value from table but after executing replace function it will be this value from table but updated

and here is a real example

UPDATE publication
SET doi = replace(doi, '10.7440/perifrasis', '10.25025/perifrasis')
WHERE doi like '10.7440/perifrasis%'

for example if we have this value

10.7440/perifrasis.2010.1.issue-1

it will become

10.25025/perifrasis.2010.1.issue-1

hope this gives you better visualization

With python 3 you can use list_a[filter] to get True values. To get False values use list_a[~filter]

See http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/htmlsingle/spring-framework-reference.html#cache-specific-config:

How can I set the TTL/TTI/Eviction policy/XXX feature?

Directly through your cache provider. The cache abstraction is... well, an abstraction not a cache implementation

So, if you use EHCache, use EHCache's configuration to configure the TTL.

You could also use Guava's CacheBuilder to build a cache, and pass this cache's ConcurrentMap view to the setStore method of the ConcurrentMapCacheFactoryBean.

try this,

    String dateStr = "17-April-2011 19:20:23.707000000 ";
    Date dateForm = new SimpleDateFormat("dd-MMMM-yyyy HH:mm:ss").parse(dateStr);
    SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");  

    String newDate = format.format(dateForm);  

    Calendar today = Calendar.getInstance();
    Date fromDate = format.parse(newDate);
    today.setTime(fromDate);
    today.add(Calendar.DAY_OF_YEAR, 1);
    Date toDate= new SimpleDateFormat("dd-MM-yyyy").parse(format.format(today.getTime()));

    Criteria crit = sessionFactory.getCurrentSession().createCriteria(Model.class);
    crit.add(Restrictions.ge("dateFieldName", fromDate));
    crit.add(Restrictions.le("dateFieldName", toDate));
    return crit.list();

You can use the following

new java.sql.Timestamp(System.currentTimeMillis()).getTime()

Result : 1539594988651

Hope this will help. Just my suggestion and not for reward points.

Using Java 8:

if(Files.exists(Paths.get(filePathString))) { 
    // do something
}

Other way to get the minor version is:

SELECT extversion
FROM pg_catalog.pg_extension
WHERE extname='postgis'

Go to your Arduino documents directory; inside you will find a directory named "Libraries". The imported library directory will be there. Just delete it and restart the Arduino app.

Your Arduino library folder should look like this (on Windows):

  My Documents\Arduino\libraries\ArduinoParty\ArduinoParty.cpp
  My Documents\Arduino\libraries\ArduinoParty\ArduinoParty.h
  My Documents\Arduino\libraries\ArduinoParty\examples
  ....

or like this (on Mac and Linux):

  Documents/Arduino/libraries/ArduinoParty/ArduinoParty.cpp

The only issue with unused libraries is the trivial amount of disk space they use. They aren't loaded automatically so don't take up any application memory of the Arduino IDE.

The answers provided above are good but let me just chip in, useState is async so if your next state is dependent on your previous state it is best you pass useState a callback. See the example below:

import { useState } from 'react';

function Example() {
    const [count, setCount] = useState(0);

  return (
    <div>
      <p>You clicked {count} times</p>
      // passing a callback to useState to update count
      <button onClick={() => setCount(count => count + 1)}>
        Click me
      </button>
    </div>
  );
}

This is the recommended way if your new state depends on computation from the old state.

Here is the generic solution to this problem.

public static <K extends Object, V extends Object> Map<K, V> getJsonAsMap(String json, K key, V value) {
    try {
      ObjectMapper mapper = new ObjectMapper();
      TypeReference<Map<K, V>> typeRef = new TypeReference<Map<K, V>>() {
      };
      return mapper.readValue(json, typeRef);
    } catch (Exception e) {
      throw new RuntimeException("Couldnt parse json:" + json, e);
    }
  }

Hope someday somebody would think to create a util method to convert to any Key/value type of Map hence this answer :)

I think agileguy has the correct answer, but I would like to add that for more difficult situations there are a couple of strategies I take to solve the problem. The first is to use a truth table. If you Google "truth table" you will run across some examples related directly to programming and computer science.

Another strategy I take is to use an anonymous function to encapsulate common logic between various conditions. Create it right before the if block, then use it where needed. This seems to create code that is more readable and maintainable.

Another option is to pass a delegate to method, which will create an XmlElement. This way the target method won't get access to whole XmlDocument, but will be able to create new elements.

As per the Wikipedia:

1. The class must have a public default constructor (with no arguments). This allows easy instantiation within editing and activation frameworks.

2. The class properties must be accessible using get, set, is (can be used for boolean properties instead of get), and other methods (so-called accessor methods and mutator methods) according to a standard naming convention. This allows easy automated inspection and updating of bean state within frameworks, many of which include custom editors for various types of properties. Setters can have one or more than one argument.

3. The class should be serializable. (This allows applications and frameworks to reliably save, store, and restore the bean's state in a manner independent of the VM and of the platform.)

For more information follow this link.

You can use Substring also for replacing with existing string:

var str = "abc awwwa";
var Index = str.indexOf('awwwa');
str = str.substring(0, Index);

On windows:

1. Remove folder from C:\Users\USER.m2
2. Close and open the project or force a change on file: pom.xml for saving :)

Leaving aside the fact that your text file is broken (U+2018 is a left quotation mark, not an apostrophe): iconv can be used to transliterate unicode characters to ascii.

You'll have to google for "iconvcodec", since the module seems not to be supported anymore and I can't find a canonical home page for it.

>>> import iconvcodec
>>> from locale import setlocale, LC_ALL
>>> setlocale(LC_ALL, '')
>>> u'\u2018'.encode('ascii//translit')
"'"

Alternatively you can use the iconv command line utility to clean up your file:

$ xxd foo
0000000: e280 980a                                ....
$ iconv -t 'ascii//translit' foo | xxd
0000000: 270a                                     '.

Personally, I prefer the simple modulo operation solution in the accepted answer. Unfortunately, SonarQube doesn't like equality tests with floating points without setting a round precision. So we have tried to find a more compliant solution. Here it is:

if (new BigDecimal(decimalValue).remainder(new BigDecimal(1)).equals(BigDecimal.ZERO)) {
    // no decimal places
} else {
    // decimal places
}

Remainder(BigDecimal) returns a BigDecimal whose value is (this % divisor). If this one's equal to zero, we know there is no floating point.

From the Jquery docs: you specify the async option to be false to get a synchronous Ajax request. Then your callback can set some data before your mother function proceeds.

Here's what your code would look like if changed as suggested:

beforecreate: function(node,targetNode,type,to) {
    jQuery.ajax({
         url:    url,
         success: function(result) {
                      if(result.isOk == false)
                          alert(result.message);
                  },
         async:   false
    });          
}

this is because $.ajax is the only request type that you can set the asynchronousity for

Here is a recursive version that handles signed integers and custom digits.

import string

def base_convert(x, base, digits=None):
    """Convert integer `x` from base 10 to base `base` using `digits` characters as digits.
    If `digits` is omitted, it will use decimal digits + lowercase letters + uppercase letters.
    """
    digits = digits or (string.digits + string.ascii_letters)
    assert 2 <= base <= len(digits), "Unsupported base: {}".format(base)
    if x == 0:
        return digits[0]
    sign = '-' if x < 0 else ''
    x = abs(x)
    first_digits = base_convert(x // base, base, digits).lstrip(digits[0])
    return sign + first_digits + digits[x % base]

Try using: Edit -> Find -> Replace in path...

The simpler and current approach for adding header to a single request is:

// Step 1

const yourHeader: HttpHeaders = new HttpHeaders({
    Authorization: 'Bearer JWT-token'
});

// POST request

this.http.post(url, body, { headers: yourHeader });

// GET request

this.http.get(url, { headers: yourHeader });

1. rebuild project in VS
2. copy project folder to iis folder, probably C:\inetpub\wwwroot\
3. in iis manager (run>inetmgr) add website, point to folder, point application pool based on your .net
4. add web service to created website, almost the same as 3.
5. INSTALL ASP for windows 7 and .net 4.0: c:\windows\microsoft.net framework\v4.(some numbers)\regiis.exe -i
6. check access to web service on your browser

First, copy the script over to Machine B using scp

[user@machineA]$ scp /path/to/script user@machineB:/home/user/path

Then, just run the script

[user@machineA]$ ssh user@machineB "/home/user/path/script"

This will work if you have given executable permission to the script.

Use another flex container to fix the min-height issue in IE10 and IE11:

HTML

<div class="ie-fixMinHeight">
    <div id="page">
        <div id="header"></div>
        <div id="content"></div>
        <div id="footer"></div>
    </div>
</div>

CSS

.ie-fixMinHeight {
    display:flex;
}

#page {
    min-height:100vh;
    width:100%;
    display:flex;
    flex-direction:column;
}

#content {
    flex-grow:1;
}

See a working demo.

• Don't use flexbox layout directly on body because it screws up elements inserted via jQuery plugins (autocomplete, popup, etc.).
• Don't use height:100% or height:100vh on your container because the footer will stick at the bottom of window and won't adapt to long content.
• Use flex-grow:1 rather than flex:1 cause IE10 and IE11 default values for flex are 0 0 auto and not 0 1 auto.

Java 8 Stream, lambda expression, functional interface

All cases handled (string null, string empty etc)

String someString = null; // something="", something="123abc", something="123123"

boolean isNumeric = Stream.of(someString)
            .filter(s -> s != null && !s.isEmpty())
            .filter(Pattern.compile("\\D").asPredicate().negate())
            .mapToLong(Long::valueOf)
            .boxed()
            .findAny()
            .isPresent();

This code will do what you're looking for. It's based on examples found here and here.

The autofmt_xdate() call is particularly useful for making the x-axis labels readable.

import numpy as np
from matplotlib import pyplot as plt

fig = plt.figure()

width = .35
ind = np.arange(len(OY))
plt.bar(ind, OY, width=width)
plt.xticks(ind + width / 2, OX)

fig.autofmt_xdate()

plt.savefig("figure.pdf")

Maybe std::ostream_iterator and std::ostringstream:

#include <vector>
#include <string>
#include <algorithm>
#include <sstream>
#include <iterator>
#include <iostream>

int main()
{
  std::vector<int> vec;
  vec.push_back(1);
  vec.push_back(4);
  vec.push_back(7);
  vec.push_back(4);
  vec.push_back(9);
  vec.push_back(7);

  std::ostringstream oss;

  if (!vec.empty())
  {
    // Convert all but the last element to avoid a trailing ","
    std::copy(vec.begin(), vec.end()-1,
        std::ostream_iterator<int>(oss, ","));

    // Now add the last element with no delimiter
    oss << vec.back();
  }

  std::cout << oss.str() << std::endl;
}

Actually... you can't use a simple regex here, at least not one. You probably need to worry about comments! Someone may write:

<!-- <content> blah </content> -->

You can take two approaches here:

1. Strip all comments out first. Then use the regex approach.
2. Do not use regular expressions and use a context sensitive parsing approach that can keep track of whether or not you are nested in a comment.

Be careful.

I am also not so sure you can match all new lines at once. @Quartz suggested this one:

<content>([^\n]*\n+)+</content>

This will match any content tags that have a newline character RIGHT BEFORE the closing tag... but I'm not sure what you mean by matching all newlines. Do you want to be able to access all the matched newline characters? If so, your best bet is to grab all content tags, and then search for all the newline chars that are nested in between. Something more like this:

<content>.*</content>

BUT THERE IS ONE CAVEAT: regexes are greedy, so this regex will match the first opening tag to the last closing one. Instead, you HAVE to suppress the regex so it is not greedy. In languages like python, you can do this with the "?" regex symbol.

I hope with this you can see some of the pitfalls and figure out how you want to proceed. You are probably better off using an XML parsing library, then iterating over all the content tags.

I know I may not be offering the best solution, but at least I hope you will see the difficulty in this and why other answers may not be right...

UPDATE 1:

Let me summarize a bit more and add some more detail to my response. I am going to use python's regex syntax because it is what I am more used to (forgive me ahead of time... you may need to escape some characters... comment on my post and I will correct it):

To strip out comments, use this regex: Notice the "?" suppresses the .* to make it non-greedy.

Similarly, to search for content tags, use: .*?

Also, You may be able to try this out, and access each newline character with the match objects groups():

<content>(.*?(\n))+.*?</content>

I know my escaping is off, but it captures the idea. This last example probably won't work, but I think it's your best bet at expressing what you want. My suggestion remains: either grab all the content tags and do it yourself, or use a parsing library.

UPDATE 2:

So here is python code that ought to work. I am still unsure what you mean by "find" all newlines. Do you want the entire lines? Or just to count how many newlines. To get the actual lines, try:

#!/usr/bin/python

import re

def FindContentNewlines(xml_text):
    # May want to compile these regexes elsewhere, but I do it here for brevity
    comments = re.compile(r"<!--.*?-->", re.DOTALL)
    content = re.compile(r"<content>(.*?)</content>", re.DOTALL)
    newlines = re.compile(r"^(.*?)$", re.MULTILINE|re.DOTALL)

    # strip comments: this actually may not be reliable for "nested comments"
    # How does xml handle <!--  <!-- --> -->. I am not sure. But that COULD
    # be trouble.
    xml_text = re.sub(comments, "", xml_text)

    result = []
    all_contents = re.findall(content, xml_text)
    for c in all_contents:
        result.extend(re.findall(newlines, c))

    return result

if __name__ == "__main__":
    example = """

<!-- This stuff
ought to be omitted
<content>
  omitted
</content>
-->

This stuff is good
<content>
<p>
  haha!
</p>
</content>

This is not found
"""
    print FindContentNewlines(example)

This program prints the result:

 ['', '<p>', '  haha!', '</p>', '']

The first and last empty strings come from the newline chars immediately preceeding the first <p> and the one coming right after the </p>. All in all this (for the most part) does the trick. Experiment with this code and refine it for your needs. Print out stuff in the middle so you can see what the regexes are matching and not matching.

Hope this helps :-).

PS - I didn't have much luck trying out my regex from my first update to capture all the newlines... let me know if you do.

From official documentation

Warning: Do not filter files with binary content like images! This will most likely result in corrupt output.

If you have both text files and binary files as resources it is recommended to have two separated folders. One folder src/main/resources (default) for the resources which are not filtered and another folder src/main/resources-filtered for the resources which are filtered.

<project>
  ...
  <build>
    ...
    <resources>
      <resource>
        <directory>src/main/resources-filtered</directory>
        <filtering>true</filtering>
      </resource>
      ...
    </resources>
    ...
  </build>
  ...
</project>

Now you can put those files into src/main/resources which should not filtered and the other files into src/main/resources-filtered.

As already mentioned filtering binary files like images,pdf`s etc. could result in corrupted output. To prevent such problems you can configure file extensions which will not being filtered.

Most certainly, You have in your directory files that cannot be filtered. So you have to specify the extensions that has not be filtered.

You can use VLOOKUP.

Assuming those are in columns A and B in Sheet1 and Sheet2 each, 22350 is in cell A2 of Sheet1, you can use:

=VLOOKUP(A2, Sheet2!A:B, 2, 0)

This will return you #N/A if there are no matches. Drag/Fill/Copy&Paste the formula to the bottom of your table and that should do it.

You are close already. Just make sure to hide the checkbox and associate it with a label you style via input[checkbox] + label

Summary of the answers

For understanding what is the best answer we can do some timing using the different solution. Unfortunately, the question was not well-posed so there are answers to different questions, here I try to point the answer to the same question. Given the array:

a = np.array([1, 3, 5, 6, 9, 10, 14, 15, 56])

The answer should be the indexes of the elements between a certain range, we assume inclusive, in this case, 6 and 10.

answer = (3, 4, 5)

Corresponding to the values 6,9,10.

To test the best answer we can use this code.

import timeit
setup = """
import numpy as np
import numexpr as ne

a = np.array([1, 3, 5, 6, 9, 10, 14, 15, 56])
# we define the left and right limit
ll = 6
rl = 10

def sorted_slice(a,l,r):
    start = np.searchsorted(a, l, 'left')
    end = np.searchsorted(a, r, 'right')
    return np.arange(start,end)
"""

functions = ['sorted_slice(a,ll,rl)', # works only for sorted values
'np.where(np.logical_and(a>=ll, a<=rl))[0]',
'np.where((a >= ll) & (a <=rl))[0]',
'np.where((a>=ll)*(a<=rl))[0]',
'np.where(np.vectorize(lambda x: ll <= x <= rl)(a))[0]',
'np.argwhere((a>=ll) & (a<=rl)).T[0]', # we traspose for getting a single row
'np.where(ne.evaluate("(ll <= a) & (a <= rl)"))[0]',]

functions2 = [
   'a[np.logical_and(a>=ll, a<=rl)]',
   'a[(a>=ll) & (a<=rl)]',
   'a[(a>=ll)*(a<=rl)]',
   'a[np.vectorize(lambda x: ll <= x <= rl)(a)]',
   'a[ne.evaluate("(ll <= a) & (a <= rl)")]',
]

Results

The results are reported in the following plot. On the top the fastest solutions. If instead of the indexes you want to extract the values you can perform the tests using functions2 but the results are almost the same.

Try following int git bash

1.git add -u :/

2.git commit -m "your commit message"

3. git push -u origin master

Note:if you have not initialized your repo.

First of all

git init 

and follow above mentioned steps in order. This worked for me

SOLUTION :-

Guess, this error is most probably returned by Local Squid deployed in the server.

So, it worked fine and good after replacing localhost by the local_ip in which the ElasticSearch has been deployed.

Use a pattern along these lines:

function getValue(file) {
  return lookupValue(file);
}

getValue('myFile.txt').then(function(res) {
  // do whatever with res here
});

(although this is a bit redundant, I'm sure your actual code is more complicated)

After running into the same issue - here're some of my thoughts:

• due to Chrome removing support for h264, on some machines, mp4 videos encoded with it will either not work (throwing an Parser error when viewing under Firebug/Network tab - consistent with issue submitted here), or crash the browser, depending upon the encoding settings
• it isn't consistent - it entirely depends upon the codecs installed on the computer - while I didn't encounter this issue on my machine, we did have one in the office where the issue occurred (and thus we used this one for testing)
• it might to do with Quicktime / divX settings (the machine in question had an older version of Quicktime than my native one - we didn't want to loose our testing pc though, so we didn't update it).

As it affects only Chrome (other browsers work fine with VideoForEverybody solution) the solution I've used is:

for every mp4 file, create a Theora encoded mp4 file (example.mp4 -> example_c.mp4) apply following js:

if (window.chrome)
    $("[type=video\\\/mp4]").each(function()
    {
        $(this).attr('src', $(this).attr('src').replace(".mp4", "_c.mp4"));
    });

Unfortunately it's a bad Chrome hack, but hey, at least it works.

This also can help: chrome could play html5 mp4 video but html5test said chrome did not support mp4 video codec

Also check your version of crome here: html5test

This answer covers a lot of ground, so it’s divided into three parts:

• How to use a CORS proxy to get around “No Access-Control-Allow-Origin header” problems
• How to avoid the CORS preflight
• How to fix “Access-Control-Allow-Origin header must not be the wildcard” problems

How to use a CORS proxy to avoid “No Access-Control-Allow-Origin header” problems

If you don’t control the server your frontend code is sending a request to, and the problem with the response from that server is just the lack of the necessary Access-Control-Allow-Origin header, you can still get things to work—by making the request through a CORS proxy.

You can easily run your own proxy using code from https://github.com/Rob--W/cors-anywhere/.
You can also easily deploy your own proxy to Heroku in just 2-3 minutes, with 5 commands:

git clone https://github.com/Rob--W/cors-anywhere.git
cd cors-anywhere/
npm install
heroku create
git push heroku master

After running those commands, you’ll end up with your own CORS Anywhere server running at, e.g., https://cryptic-headland-94862.herokuapp.com/.

Now, prefix your request URL with the URL for your proxy:

https://cryptic-headland-94862.herokuapp.com/https://example.com

Adding the proxy URL as a prefix causes the request to get made through your proxy, which then:

1. Forwards the request to https://example.com.
2. Receives the response from https://example.com.
3. Adds the Access-Control-Allow-Origin header to the response.
4. Passes that response, with that added header, back to the requesting frontend code.

The browser then allows the frontend code to access the response, because that response with the Access-Control-Allow-Origin response header is what the browser sees.

This works even if the request is one that triggers browsers to do a CORS preflight OPTIONS request, because in that case, the proxy also sends back the Access-Control-Allow-Headers and Access-Control-Allow-Methods headers needed to make the preflight successful.

How to avoid the CORS preflight

The code in the question triggers a CORS preflight—since it sends an Authorization header.

https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Preflighted_requests

Even without that, the Content-Type: application/json header would also trigger a preflight.

What “preflight” means: before the browser tries the POST in the code in the question, it’ll first send an OPTIONS request to the server — to determine if the server is opting-in to receiving a cross-origin POST that has Authorization and Content-Type: application/json headers.

It works pretty well with a small curl script - I get my data.

To properly test with curl, you must emulate the preflight OPTIONS request the browser sends:

curl -i -X OPTIONS -H "Origin: http://127.0.0.1:3000" \
    -H 'Access-Control-Request-Method: POST' \
    -H 'Access-Control-Request-Headers: Content-Type, Authorization' \
    "https://the.sign_in.url"

…with https://the.sign_in.url replaced by whatever your actual sign_in URL is.

The response the browser needs to see from that OPTIONS request must have headers like this:

Access-Control-Allow-Origin:  http://127.0.0.1:3000
Access-Control-Allow-Methods: POST
Access-Control-Allow-Headers: Content-Type, Authorization

If the OPTIONS response doesn’t include those headers, then the browser will stop right there and never even attempt to send the POST request. Also, the HTTP status code for the response must be a 2xx—typically 200 or 204. If it’s any other status code, the browser will stop right there.

The server in the question is responding to the OPTIONS request with a 501 status code, which apparently means it’s trying to indicate it doesn’t implement support for OPTIONS requests. Other servers typically respond with a 405 “Method not allowed” status code in this case.

So you’re never going to be able to make POST requests directly to that server from your frontend JavaScript code if the server responds to that OPTIONS request with a 405 or 501 or anything other than a 200 or 204 or if doesn’t respond with those necessary response headers.

The way to avoid triggering a preflight for the case in the question would be:

• if the server didn’t require an Authorization request header but instead, e.g., relied on authentication data embedded in the body of the POST request or as a query param
• if the server didn’t require the POST body to have a Content-Type: application/json media type but instead accepted the POST body as application/x-www-form-urlencoded with a parameter named json (or whatever) whose value is the JSON data

How to fix “Access-Control-Allow-Origin header must not be the wildcard” problems

I am getting another error message:

The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://127.0.0.1:3000' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

For a request that includes credentials, browsers won’t let your frontend JavaScript code access the response if the value of the Access-Control-Allow-Origin response header is *. Instead the value in that case must exactly match your frontend code’s origin, http://127.0.0.1:3000.

See Credentialed requests and wildcards in the MDN HTTP access control (CORS) article.

If you control the server you’re sending the request to, then a common way to deal with this case is to configure the server to take the value of the Origin request header, and echo/reflect that back into the value of the Access-Control-Allow-Origin response header; e.g., with nginx:

add_header Access-Control-Allow-Origin $http_origin

But that’s just an example; other (web) server systems provide similar ways to echo origin values.

I am using Chrome. I also tried using that Chrome CORS Plugin

That Chrome CORS plugin apparently just simplemindedly injects an Access-Control-Allow-Origin: * header into the response the browser sees. If the plugin were smarter, what it would be doing is setting the value of that fake Access-Control-Allow-Origin response header to the actual origin of your frontend JavaScript code, http://127.0.0.1:3000.

So avoid using that plugin, even for testing. It’s just a distraction. To test what responses you get from the server with no browser filtering them, you’re better off using curl -H as above.

As far as the frontend JavaScript code for the fetch(…) request in the question:

headers.append('Access-Control-Allow-Origin', 'http://localhost:3000');
headers.append('Access-Control-Allow-Credentials', 'true');

Remove those lines. The Access-Control-Allow-* headers are response headers. You never want to send them in a request. The only effect that’ll have is to trigger a browser to do a preflight.

Good evening,

The previous clues to get SQLManagementStudio_x64_ENU.exe runing didn't work as stated for me. After a while of searching, trying, retrying again and again, I finally figured it out. When executing SQLManagementStudio_x64_ENU.exe on my Windows seven system, I kept runing into compatibility issues. The trick is to run SQLManagementStudio_x64_ENU.exe in compatibility mode with Windows XP SP2. Edit the installer properties and enable compatibility mode with XP (service pack 2), then you'll be able to access Mr Doug (answered Mar 4 at 15:09) resolution.

Cheers.

Note setValue only works if there are already predefined set of values for the selectize control ( ex. select field ), for controls where the value could be dynamic ( ex. user can add values on the fly, textbox field ) setValue ain't gonna work.

Use createItem functon instead for adding and setting the current value of the selectize field

ex.

$selectize[ 0 ].selectize.clear(); // Clear existing entries
for ( var i = 0 ; i < data_source.length ; i++ ) // data_source is a dynamic source of data
    $selectize[ 0 ].selectize.createItem( data_source[ i ] , false ); // false means don't trigger dropdown

Your problem is that you have 64-bit eclipse running but you have 32 bit JRE.So please download JRE for 64 bit windows and let it install on the default location. Finally add that path till bin in your PATH variable. Try it should work.

XSD:
XSD (XML Schema Definition) specifies how to formally describe the elements in an Extensible Markup Language (XML) document.
Xml:
XML was designed to describe data.It is independent from software as well as hardware.
It enhances the following things.
-Data sharing.
-Platform independent.
-Increasing the availability of Data.

Differences:

1. XSD is based and written on XML.

2. XSD defines elements and structures that can appear in the document, while XML does not.

3. XSD ensures that the data is properly interpreted, while XML does not.

4. An XSD document is validated as XML, but the opposite may not always be true.

5. XSD is better at catching errors than XML.

An XSD defines elements that can be used in the documents, relating to the actual data with which it is to be encoded.
for eg:
A date that is expressed as 1/12/2010 can either mean January 12 or December 1st. Declaring a date data type in an XSD document, ensures that it follows the format dictated by XSD.

There is no need no use the date() method from PHP if you don't use a timestamp. If dateposted is a datetime column, you can insert the current date like this:

$db->query("INSERT INTO table (dateposted) VALUES (now())");

EDIT: Updated for jQuery 1.8

Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: Added code to make it a jQuery function.

For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
                 '-moz-transform' : 'rotate('+ degrees +'deg)',
                 '-ms-transform' : 'rotate('+ degrees +'deg)',
                 'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.

Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.

Here is a jsFiddle.

If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.

HTML

<div class="rotate">
    <h1>Rotatey text</h1>
</div>

CSS

/* Totally for style */
.rotate {
    background: #F02311;
    color: #FFF;
    width: 200px;
    height: 200px;
    text-align: center;
    font: normal 1em Arial;
    position: relative;
    top: 50px;
    left: 50px;
}

/* The real code */
.rotated {
    -webkit-transform: rotate(45deg);  /* Chrome, Safari 3.1+ */
    -moz-transform: rotate(45deg);  /* Firefox 3.5-15 */
    -ms-transform: rotate(45deg);  /* IE 9 */
    -o-transform: rotate(45deg);  /* Opera 10.50-12.00 */
    transform: rotate(45deg);  /* Firefox 16+, IE 10+, Opera 12.10+ */
}

jQuery

Make sure these are wrapped in $(document).ready

$('.rotate').click(function() {
    $(this).toggleClass('rotated');
});

Custom intervals

var rotation = 0;
$('.rotate').click(function() {
    rotation += 5;
    $(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
                 '-moz-transform' : 'rotate('+ rotation +'deg)',
                 '-ms-transform' : 'rotate('+ rotation +'deg)',
                 'transform' : 'rotate('+ rotation +'deg)'});
});

I know this is an old question, but I had the same issue and here is what I came up with and hopefully will be useful to someone. This will allow passing JSON formatted parameters individually in request URL (GET), as one single JSON object after ? (GET) or within single JSON body object (POST). My goal was RPC-style functionality.

Created a custom attribute and parameter binding, inheriting from HttpParameterBinding:

public class JSONParamBindingAttribute : Attribute
{

}

public class JSONParamBinding : HttpParameterBinding
{

    private static JsonSerializer _serializer = JsonSerializer.Create(new JsonSerializerSettings()
    {
        DateTimeZoneHandling = DateTimeZoneHandling.Utc
    });


    public JSONParamBinding(HttpParameterDescriptor descriptor)
        : base(descriptor)
    {
    }

    public override Task ExecuteBindingAsync(ModelMetadataProvider metadataProvider,
                                                HttpActionContext actionContext,
                                                CancellationToken cancellationToken)
    {
        JObject jobj = GetJSONParameters(actionContext.Request);

        object value = null;

        JToken jTokenVal = null;
        if (!jobj.TryGetValue(Descriptor.ParameterName, out jTokenVal))
        {
            if (Descriptor.IsOptional)
                value = Descriptor.DefaultValue;
            else
                throw new MissingFieldException("Missing parameter : " + Descriptor.ParameterName);
        }
        else
        {
            try
            {
                value = jTokenVal.ToObject(Descriptor.ParameterType, _serializer);
            }
            catch (Newtonsoft.Json.JsonException e)
            {
                throw new HttpParseException(String.Join("", "Unable to parse parameter: ", Descriptor.ParameterName, ". Type: ", Descriptor.ParameterType.ToString()));
            }
        }

        // Set the binding result here
        SetValue(actionContext, value);

        // now, we can return a completed task with no result
        TaskCompletionSource<AsyncVoid> tcs = new TaskCompletionSource<AsyncVoid>();
        tcs.SetResult(default(AsyncVoid));
        return tcs.Task;
    }

    public static HttpParameterBinding HookupParameterBinding(HttpParameterDescriptor descriptor)
    {
        if (descriptor.ActionDescriptor.ControllerDescriptor.GetCustomAttributes<JSONParamBindingAttribute>().Count == 0 
            && descriptor.ActionDescriptor.GetCustomAttributes<JSONParamBindingAttribute>().Count == 0)
            return null;

        var supportedMethods = descriptor.ActionDescriptor.SupportedHttpMethods;

        if (supportedMethods.Contains(HttpMethod.Post) || supportedMethods.Contains(HttpMethod.Get))
        {
            return new JSONParamBinding(descriptor);
        }

        return null;
    }

    private JObject GetJSONParameters(HttpRequestMessage request)
    {
        JObject jobj = null;
        object result = null;
        if (!request.Properties.TryGetValue("ParamsJSObject", out result))
        {
            if (request.Method == HttpMethod.Post)
            {
                jobj = JObject.Parse(request.Content.ReadAsStringAsync().Result);
            }
            else if (request.RequestUri.Query.StartsWith("?%7B"))
            {
                jobj = JObject.Parse(HttpUtility.UrlDecode(request.RequestUri.Query).TrimStart('?'));
            }
            else
            {
                jobj = new JObject();
                foreach (var kvp in request.GetQueryNameValuePairs())
                {
                    jobj.Add(kvp.Key, JToken.Parse(kvp.Value));
                }
            }
            request.Properties.Add("ParamsJSObject", jobj);
        }
        else
        {
            jobj = (JObject)result;
        }

        return jobj;
    }



    private struct AsyncVoid
    {
    }
}

Inject binding rule inside WebApiConfig.cs's Register method:

        public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services

            // Web API routes
            config.MapHttpAttributeRoutes();

            config.ParameterBindingRules.Insert(0, JSONParamBinding.HookupParameterBinding);

            config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
        }

This allows for controller actions with default parameter values and mixed complexity, as such:

[JSONParamBinding]
    [HttpPost, HttpGet]
    public Widget DoWidgetStuff(Widget widget, int stockCount, string comment="no comment")
    {
        ... do stuff, return Widget object
    }

example post body:

{ 
    "widget": { 
        "a": 1, 
        "b": "string", 
        "c": { "other": "things" } 
    }, 
    "stockCount": 42, 
    "comment": "sample code"
} 

or GET single param (needs URL encoding)

controllerPath/DoWidgetStuff?{"widget":{..},"comment":"test","stockCount":42}

or GET multiple param (needs URL encoding)

controllerPath/DoWidgetStuff?widget={..}&comment="test"&stockCount=42

This is a perfect use-case for DISTINCT ON - a Postgres specific extension of the standard DISTINCT:

SELECT DISTINCT ON (category)
       id  -- , category, date  -- any other column (expression) from the same row
FROM   tbl
ORDER  BY category, date DESC;

Careful with descending sort order. If the column can be NULL, you may want to add NULLS LAST:

• Sort by column ASC, but NULL values first?

DISTINCT ON is simple and fast. Detailed explanation in this related answer:

• Select first row in each GROUP BY group?

For big tables with many rows per category consider an alternative approach:

• Optimize GROUP BY query to retrieve latest row per user
• Optimize groupwise maximum query

For clarity, I'd like to illustrate @Joey's answer above with these gifs :

Try this:

foreach (var dept in employees.SelectMany(e => e.Departments))
{
   dept.SomeProperty = null;
   collection.Add(dept);
}

$('div.target').each(function() {
   /* Measure the width of each image. */
   var test = $(this).find('.scrolling img').width();

   /* Find out how many images there are. */
   var testimg = $(this).find('.scrolling img').length;

   /* Do the maths. */
   var final = (test* testimg)*1.2;

   /* Apply the maths to the CSS. */
   $(this).find('scrolling').width(final); 
});

Here you loop through all your div's with class target and you do the calculations. Within this loop you can simply use $(this) to indicate the currently selected <div> tag.

For me the project was compiled outside the project. I just change the path. For changing the path (i'm using mac).

• Go to File --> Project Structure
• Go to Module on left side.
• Select Paths, select radio button(use module compile output path)
• Provide output path and Test output path which is inside your project
• Deselect Exclude output paths.
• Go to File --> Click on Invalidate Cache and restart

except Michael Anderson's answer, i have coding with other two way in my project.

First:

you can white all variable to one class. created a kotlin file named Const

object Const {
    const val FIRST_NAME_1 = "just"
    const val LAST_NAME_1 = "YuMu"
}

You can use it in kotlin and java code

 Log.d("stackoverflow", Const.FIRST_NAME_1)

Second:

You can use Kotlin's extension function
created a kotlin file named Ext, below code is the all code in Ext file

package pro.just.yumu

/**
 * Created by lpf on 2020-03-18.
 */

const val FIRST_NAME = "just"
const val LAST_NAME = "YuMu"

You can use it in kotlin code

 Log.d("stackoverflow", FIRST_NAME)

You can use it in java code

 Log.d("stackoverflow", ExtKt.FIRST_NAME);

You'll have to use the ChannelFactory class.

Here's an example:

var myBinding = new BasicHttpBinding();
var myEndpoint = new EndpointAddress("http://localhost/myservice");
using (var myChannelFactory = new ChannelFactory<IMyService>(myBinding, myEndpoint))
{
    IMyService client = null;

    try
    {
        client = myChannelFactory.CreateChannel();
        client.MyServiceOperation();
        ((ICommunicationObject)client).Close();
        myChannelFactory.Close();
    }
    catch
    {
        (client as ICommunicationObject)?.Abort();
    }
}

Related resources:

• How to: Use the ChannelFactory

The real problem is that you are using dynamic return type in the FacebookClient Get method. And although you use a method for serializing, the JSON converter cannot deserialize this Object after that.

Use insted of:

dynamic result = client.Get("fql", new { q = "select target_id,target_type from connection where source_id = me()"}); 
string jsonstring = JsonConvert.SerializeObject(result);

something like that:

string result = client.Get("fql", new { q = "select target_id,target_type from connection where source_id = me()"}).ToString();

Then you can use DeserializeObject method:

var datalist = JsonConvert.DeserializeObject<List<RootObject>>(result);

Hope this helps.

Here's a slight modification of Harry's answer that focuses on elevated status; I'm using this at the start of an install.bat file:

set IS_ELEVATED=0
whoami /groups | findstr /b /c:"Mandatory Label\High Mandatory Level" | findstr /c:"Enabled group" > nul: && set IS_ELEVATED=1
if %IS_ELEVATED%==0 (
    echo You must run the command prompt as administrator to install.
    exit /b 1
)

This definitely worked for me and the principle seems to be sound; from MSFT's Chris Jackson:

When you are running elevated, your token contains an ACE called Mandatory Label\High Mandatory Level.

If you just want to install PHP no matter what version it is, try PHP7

sudo apt-get install php7.0 php7.0-mcrypt

You can do this using the query builder. Just use SELECT instead of TABLE and GET.

DB::select('select * from user where name = ?',['Jhon']);

Notes: 1. Multiple question marks are allowed. 2. The second parameter must be an array, even if there is only one parameter. 3. Laravel will automatically clean parameters, so you don't have to.

Hmmmmmm, turns out that still returns a standard class for me when I don't use a where clause. I found this helped:

foreach($results as $result)
{
print_r(get_object_vars($result));
}

However, get_object_vars isn't recursive, so don't use it on $results.

i did this:

$("#myModal").modal({}).draggable();

and it make my very standard/basic modal draggable.

not sure how/why it worked, but it did.

VBA uses a garbage collector which is implemented by reference counting.

There can be multiple references to a given object (for example, Dim aw = ActiveWorkbook creates a new reference to Active Workbook), so the garbage collector only cleans up an object when it is clear that there are no other references. Setting to Nothing is an explicit way of decrementing the reference count. The count is implicitly decremented when you exit scope.

Strictly speaking, in modern Excel versions (2010+) setting to Nothing isn't necessary, but there were issues with older versions of Excel (for which the workaround was to explicitly set)

If you have a list of allowed values, you can easily retain them in an object using:

const raw = {_x000D_
  item1: { key: 'sdfd', value:'sdfd' },_x000D_
  item2: { key: 'sdfd', value:'sdfd' },_x000D_
  item3: { key: 'sdfd', value:'sdfd' }_x000D_
};_x000D_
_x000D_
const allowed = ['item1', 'item3'];_x000D_
_x000D_
const filtered = Object.keys(raw)_x000D_
  .filter(key => allowed.includes(key))_x000D_
  .reduce((obj, key) => {_x000D_
    obj[key] = raw[key];_x000D_
    return obj;_x000D_
  }, {});_x000D_
_x000D_
console.log(filtered);

This uses:

1. Object.keys to list all properties in raw (the original data), then
2. Array.prototype.filter to select keys that are present in the allowed list, using
   1. Array.prototype.includes to make sure they are present
3. Array.prototype.reduce to build a new object with only the allowed properties.

This will make a shallow copy with the allowed properties (but won't copy the properties themselves).

You can also use the object spread operator to create a series of objects without mutating them (thanks to rjerue for mentioning this):

const raw = {_x000D_
  item1: { key: 'sdfd', value:'sdfd' },_x000D_
  item2: { key: 'sdfd', value:'sdfd' },_x000D_
  item3: { key: 'sdfd', value:'sdfd' }_x000D_
};_x000D_
_x000D_
const allowed = ['item1', 'item3'];_x000D_
_x000D_
const filtered = Object.keys(raw)_x000D_
  .filter(key => allowed.includes(key))_x000D_
  .reduce((obj, key) => {_x000D_
    return {_x000D_
      ...obj,_x000D_
      [key]: raw[key]_x000D_
    };_x000D_
  }, {});_x000D_
_x000D_
console.log(filtered);

For purposes of trivia, if you wanted to remove the unwanted fields from the original data (which I would not recommend doing, since it involves some ugly mutations), you could invert the includes check like so:

const raw = {_x000D_
  item1: { key: 'sdfd', value:'sdfd' },_x000D_
  item2: { key: 'sdfd', value:'sdfd' },_x000D_
  item3: { key: 'sdfd', value:'sdfd' }_x000D_
};_x000D_
_x000D_
const allowed = ['item1', 'item3'];_x000D_
_x000D_
Object.keys(raw)_x000D_
  .filter(key => !allowed.includes(key))_x000D_
  .forEach(key => delete raw[key]);_x000D_
_x000D_
console.log(raw);

I'm including this example to show a mutation-based solution, but I don't suggest using it.

items=re.findall("token.*$",s,re.MULTILINE)
>>> for x in items:

you can also get the line if there are other characters before token

items=re.findall("^.*token.*$",s,re.MULTILINE)

The above works like grep token on unix and keyword 'in' or .contains in python and C#

s='''
qwertyuiop
asdfghjkl

zxcvbnm
token qwerty

asdfghjklñ
'''

http://pythex.org/ matches the following 2 lines

....
....
token qwerty

If you also want to preserve the original file name, try with:

wget --content-disposition --trust-server-names -i list_of_urls.txt

Suppose logical address space is **32 bit so total possible logical entries will be 2^32 and other hand suppose each page size is 4 byte then size of one page is *2^2*2^10=2^12...* now we know that no. of pages in page table is pages=total possible logical address entries/page size so pages=2^32/2^12 =2^20 Now suppose that each entry in page table takes 4 bytes then total size of page table in *physical memory will be=2^2*2^20=2^22=4mb***

You're declaring everything in the parent page. So the references to window and document are to the parent page's. If you want to do stuff to the iframe's, use iframe || iframe.contentWindow to access its window, and iframe.contentDocument || iframe.contentWindow.document to access its document.

There's a word for what's happening, possibly "lexical scope": What is lexical scope?

The only context of a scope is this. And in your example, the owner of the method is doc, which is the iframe's document. Other than that, anything that's accessed in this function that uses known objects are the parent's (if not declared in the function). It would be a different story if the function were declared in a different place, but it's declared in the parent page.

This is how I would write it:

(function () {
  var dom, win, doc, where, iframe;

  iframe = document.createElement('iframe');
  iframe.src = "javascript:false";

  where = document.getElementsByTagName('script')[0];
  where.parentNode.insertBefore(iframe, where);

  win = iframe.contentWindow || iframe;
  doc = iframe.contentDocument || iframe.contentWindow.document;

  doc.open();
  doc._l = (function (w, d) {
    return function () {
      w.vanishing_global = new Date().getTime();

      var js = d.createElement("script");
      js.src = 'test-vanishing-global.js?' + w.vanishing_global;

      w.name = "foobar";
      d.foobar = "foobar:" + Math.random();
      d.foobar = "barfoo:" + Math.random();
      d.body.appendChild(js);
    };
  })(win, doc);
  doc.write('<body onload="document._l();"></body>');
  doc.close();
})();

The aliasing of win and doc as w and d aren't necessary, it just might make it less confusing because of the misunderstanding of scopes. This way, they are parameters and you have to reference them to access the iframe's stuff. If you want to access the parent's, you still use window and document.

I'm not sure what the implications are of adding methods to a document (doc in this case), but it might make more sense to set the _l method on win. That way, things can be run without a prefix...such as <body onload="_l();"></body>

You could do something like:

find . -type d > dirs.txt

to create the list of directories, then

xargs mkdir -p < dirs.txt

to create the directories on the destination.

To search for specifil file types in visual studio code.
Type ctrl+p and then search for something like *.py.
Simple and easy

Max value for a particular column of a dataframe can be achieved by using -

your_max_value = df.agg({"your-column": "max"}).collect()[0][0]

You can try Salar.Bois serializer which has a decent performance. Its focus is on payload size but it also offers good performance.

There are benchmarks in the Github page if you wish to see and compare the results by yourself.

https://github.com/salarcode/Bois

also,

the global new and delete can be overridden, malloc/free cannot.

further more new and delete can be overridden per type.

If your branch is behind by master then do:

git checkout master (you are switching your branch to master)
git pull 
git checkout yourBranch (switch back to your branch)
git merge master

After merging it, check if there is a conflict or not.
If there is NO CONFLICT then:

git push

If there is a conflict then fix your file(s), then:

git add yourFile(s)
git commit -m 'updating my branch'
git push

UPDATE:

If you want to take advantage of Imagick (if it is installed on your server). Note: I didn't use Imagick's nature writeFile because I was having issues with it on my server. File put contents works just as well.

<?php
/**

 */
function generateThumbnail($img, $width, $height, $quality = 90)
{
    if (is_file($img)) {
        $imagick = new Imagick(realpath($img));
        $imagick->setImageFormat('jpeg');
        $imagick->setImageCompression(Imagick::COMPRESSION_JPEG);
        $imagick->setImageCompressionQuality($quality);
        $imagick->thumbnailImage($width, $height, false, false);
        $filename_no_ext = reset(explode('.', $img));
        if (file_put_contents($filename_no_ext . '_thumb' . '.jpg', $imagick) === false) {
            throw new Exception("Could not put contents.");
        }
        return true;
    }
    else {
        throw new Exception("No valid image provided with {$img}.");
    }
}

// example usage
try {
    generateThumbnail('test.jpg', 100, 50, 65);
}
catch (ImagickException $e) {
    echo $e->getMessage();
}
catch (Exception $e) {
    echo $e->getMessage();
}
?>

I have been using this, just execute the function after you store the original image and use that location to create the thumbnail. Edit it to your liking...

function makeThumbnails($updir, $img, $id)
{
    $thumbnail_width = 134;
    $thumbnail_height = 189;
    $thumb_beforeword = "thumb";
    $arr_image_details = getimagesize("$updir" . $id . '_' . "$img"); // pass id to thumb name
    $original_width = $arr_image_details[0];
    $original_height = $arr_image_details[1];
    if ($original_width > $original_height) {
        $new_width = $thumbnail_width;
        $new_height = intval($original_height * $new_width / $original_width);
    } else {
        $new_height = $thumbnail_height;
        $new_width = intval($original_width * $new_height / $original_height);
    }
    $dest_x = intval(($thumbnail_width - $new_width) / 2);
    $dest_y = intval(($thumbnail_height - $new_height) / 2);
    if ($arr_image_details[2] == IMAGETYPE_GIF) {
        $imgt = "ImageGIF";
        $imgcreatefrom = "ImageCreateFromGIF";
    }
    if ($arr_image_details[2] == IMAGETYPE_JPEG) {
        $imgt = "ImageJPEG";
        $imgcreatefrom = "ImageCreateFromJPEG";
    }
    if ($arr_image_details[2] == IMAGETYPE_PNG) {
        $imgt = "ImagePNG";
        $imgcreatefrom = "ImageCreateFromPNG";
    }
    if ($imgt) {
        $old_image = $imgcreatefrom("$updir" . $id . '_' . "$img");
        $new_image = imagecreatetruecolor($thumbnail_width, $thumbnail_height);
        imagecopyresized($new_image, $old_image, $dest_x, $dest_y, 0, 0, $new_width, $new_height, $original_width, $original_height);
        $imgt($new_image, "$updir" . $id . '_' . "$thumb_beforeword" . "$img");
    }
}

The above function creates images with a uniform thumbnail size. If the image doesn't have the same dimensions as the specified thumbnail size (proportionally), it just has blackspace on the top and bottom.

I got the same error using Eclipse trying to execute a Gradle Task. Every time I run a command (i.e. war) the process threw an exception like:

Could not find tools.jar. Please check that C:\Program Files\Java\Jre8" is a valid JDK install.

I tried the solution listed in this post but none of them solved this issue. Here my solution :

1. Go to the "Gradle Task" view
2. Right Click on the task you want to execute
3. Select Open Gradle Run Configuration
4. In the tab "Java Home" select your local JDK repository then click OK

Run again, Enjoy!

Please NOTE that this procedure of adding the reporting services described by @Rich Shealer above will be iterated every time you start a different project. In order to avoid that:

1. If you may need to set up a different computer (eg, at home without internet), then keep your downloaded installers from the marketplace somewhere safe, ie:

   • Microsoft.DataTools.ReportingServices.vsix, and
   • Microsoft.RdlcDesigner.vsix

2. Fetch the following libraries from the packages or bin folder of the application you have created with reporting services in it:

   • Microsoft.ReportViewer.Common.dll
   • Microsoft.ReportViewer.DataVisualization.dll
   • Microsoft.ReportViewer.Design.dll
   • Microsoft.ReportViewer.ProcessingObjectModel.dll
   • Microsoft.ReportViewer.WinForms.dll

3. Install the 2 components from 1 above

4. Add the dlls from 2 above as references (Project>References>Add...)
5. (Optional) Add Reporting tab to the toolbar
6. Add Items to Reporting tab
7. Browse to the bin folder or where you have the above dlls and add them

You are now good to go! ReportViewer icon will be added to your toolbar, and you will also now find Report and ReportWizard templates added to your Common list of templates when you want to add a New Item... (Report) to your project

NB: When set up using Nuget package manager, the Report and ReportWizard templates are grouped under Reporting. Using my method described above however does not add the Reporting grouping in installed templates, but I dont think it is any trouble given that it enables you to quickly integrate rdlc without internet and without downloading what you already have from Nuget every time!

In SQL Server Management Studio you can right click on the database you want to replicate, and select "Script Database as" to have the tool create the appropriate SQL file to replicate that database on another server. You can repeat this process for each table you want to create, and then merge the files into a single SQL file. Don't forget to add a using statement after you create your Database but prior to any table creation.

In more recent versions of SQL Server you can get this in one file in SSMS.

1. Right click a database.
2. Tasks
3. Generate Scripts

This will launch a wizard where you can script the entire database or just portions. There does not appear to be a T-SQL way of doing this.

     string ImagePath = "";

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(ImagePath);
        string a = "";
        try
        {
            HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
            Stream receiveStream = response.GetResponseStream();
            if (receiveStream.CanRead)
            { a = "OK"; }
        }

        catch { }

TL:DR; return promises from you actions only when necessary, but DRY chaining the same actions.

For a long time I also though that returning actions contradicts the Vuex cycle of uni-directional data flow.

But, there are EDGE CASES where returning a promise from your actions might be "necessary".

Imagine a situation where an action can be triggered from 2 different components, and each handles the failure case differently. In that case, one would need to pass the caller component as a parameter to set different flags in the store.

Dumb example

Page where the user can edit the username in navbar and in /profile page (which contains the navbar). Both trigger an action "change username", which is asynchronous. If the promise fails, the page should only display an error in the component the user was trying to change the username from.

Of course it is a dumb example, but I don't see a way to solve this issue without duplicating code and making the same call in 2 different actions.

I know this is an old thread but thought I should mention that the extern keyword. I've recently ran into this issue and solved as follows

Helper.h

namespace DX
{
    extern inline void ThrowIfFailed(HRESULT hr);
}

Helper.cpp

namespace DX
{
    inline void ThrowIfFailed(HRESULT hr)
    {
        if (FAILED(hr))
        {
            std::stringstream ss;
            ss << "#" << hr;
            throw std::exception(ss.str().c_str());
        }
    }
}

In C#, there are at least 4 ways to embed a quote within a string:

1. Escape quote with a backslash
2. Precede string with @ and use double quotes
3. Use the corresponding ASCII character
4. Use the Hexadecimal Unicode character

Please refer this document for detailed explanation.

var context = new DatabaseEntities();

var t = new test //Make sure you have a table called test in DB
{
    ID = Guid.NewGuid(),
    name = "blah",
};

context.test.Add(t);
context.SaveChanges();

Should do it

just in case you are on Unix, you can use time to get the execution time:

$ g++ myprog.cpp -o myprog
$ time ./myprog

Another answer is to force xargs to process the commands in batches. For instance to delete the files 100 at a time, cd into the directory and run this:

echo *.pdf | xargs -n 100 rm

Maybe you want set -e:

www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:

This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.

As of others have explained how to do it using str_replace, you can also use regex to achieve this.

$name = preg_replace('/\s+/', '_', $name);

I have used this query in our production code for nearly 10 years:

SELECT FLOOR((CAST (GetDate() AS INTEGER) - CAST(Date_of_birth AS INTEGER)) / 365.25) AS Age

As Luiggi mentioned you need to change your main to:

import java.util.Arrays;

public class trial1{

    public static void main(String[] args){
        int[] A = numbers();
        System.out.println(Arrays.toString(A)); //Might require import of util.Arrays
    }

    public static int[] numbers(){
        int[] A = {1,2,3};
        return A;
    }
}

It is not possible to find the number of elements in an array unless it is a character array. Consider the below example:

int main()
{
    int arr[100]={1,2,3,4,5};
    int size = sizeof(arr)/sizeof(arr[0]);
    printf("%d", size);
    return 1;
}

The above value gives us value 100 even if the number of elements is five. If it is a character array, you can search linearly for the null string at the end of the array and increase the counter as you go through.

Java has 5 different boolean compare operators: &, &&, |, ||, ^

& and && are "and" operators, | and || "or" operators, ^ is "xor"

The single ones will check every parameter, regardless of the values, before checking the values of the parameters. The double ones will first check the left parameter and its value and if true (||) or false (&&) leave the second one untouched. Sound compilcated? An easy example should make it clear:

Given for all examples:

 String aString = null;

AND:

 if (aString != null & aString.equals("lala"))

Both parameters are checked before the evaluation is done and a NullPointerException will be thrown for the second parameter.

 if (aString != null && aString.equals("lala"))

The first parameter is checked and it returns false, so the second paramter won't be checked, because the result is false anyway.

The same for OR:

 if (aString == null | !aString.equals("lala"))

Will raise NullPointerException, too.

 if (aString == null || !aString.equals("lala"))

The first parameter is checked and it returns true, so the second paramter won't be checked, because the result is true anyway.

XOR can't be optimized, because it depends on both parameters.
