Check project configuration. Linker->System->SubSystem should be Windows.

You have it right. The stack pointer points to the top item on the stack and the base pointer points to the "previous" top of the stack before the function was called.

When you call a function, any local variable will be stored on the stack and the stack pointer will be incremented. When you return from the function, all the local variables on the stack go out of scope. You do this by setting the stack pointer back to the base pointer (which was the "previous" top before the function call).

Doing memory allocation this way is very, very fast and efficient.

You have to surround the select part with parenthesis.

CREATE TABLE SCHEMA.NEW_TB AS (
    SELECT *
    FROM SCHEMA.OLD_TB
) WITH NO DATA

Should work. Pay attention to all the things @Gilbert said would not be copied.

I'm assuming DB2 on Linux/Unix/Windows here, since you say DB2 v9.5.

I managed to make it possible to dynamically add a column using just a line of code like this:

MyItemsCollection.AddPropertyDescriptor(
    new DynamicPropertyDescriptor<User, int>("Age", x => x.Age));

Regarding to the question, this is not a XAML-based solution (since as mentioned there is no reasonable way to do it), neither it is a solution which would operate directly with DataGrid.Columns. It actually operates with DataGrid bound ItemsSource, which implements ITypedList and as such provides custom methods for PropertyDescriptor retrieval. In one place in code you can define "data rows" and "data columns" for your grid.

If you would have:

IList<string> ColumnNames { get; set; }
//dict.key is column name, dict.value is value
Dictionary<string, string> Rows { get; set; }

you could use for example:

var descriptors= new List<PropertyDescriptor>();
//retrieve column name from preprepared list or retrieve from one of the items in dictionary
foreach(var columnName in ColumnNames)
    descriptors.Add(new DynamicPropertyDescriptor<Dictionary, string>(ColumnName, x => x[columnName]))
MyItemsCollection = new DynamicDataGridSource(Rows, descriptors) 

and your grid using binding to MyItemsCollection would be populated with corresponding columns. Those columns can be modified (new added or existing removed) at runtime dynamically and grid will automatically refresh it's columns collection.

DynamicPropertyDescriptor mentioned above is just an upgrade to regular PropertyDescriptor and provides strongly-typed columns definition with some additional options. DynamicDataGridSource would otherwise work just fine event with basic PropertyDescriptor.

You can simply make your action result as NoContentResult on controller

public NoContentResult UploadFile([FromForm] VwModel model)
    {
       return new NoContentResult();
    } 

typeof(BaseClass).IsAssignableFrom(unknownType);

There is an excellent eluceo/ical package that allows you to easily create ics files.

Here is an example usage from docs:

// 1. Create new calendar
$vCalendar = new \Eluceo\iCal\Component\Calendar('www.example.com');

// 2. Create an event
$vEvent = new \Eluceo\iCal\Component\Event();
$vEvent->setDtStart(new \DateTime('2012-12-24'));
$vEvent->setDtEnd(new \DateTime('2012-12-24'));
$vEvent->setNoTime(true);
$vEvent->setSummary('Christmas');

// Adding Timezone (optional)
$vEvent->setUseTimezone(true);

// 3. Add event to calendar
$vCalendar->addComponent($vEvent);

// 4. Set headers
header('Content-Type: text/calendar; charset=utf-8');
header('Content-Disposition: attachment; filename="cal.ics"');

// 5. Output
echo $vCalendar->render();

% mysql --user=root mysql

This worked on Mac, using csv and opening the file in Excel.

Using python to write the csv file.

data= '"first line of cell a1\r 2nd line in cell a1\r 3rd line in cell a1","cell b1","1st line in cell c1\r 2nd line in cell c1"\n"first line in cell a2"\n'

file.write(data)

Here is another variant that uses a mix of the two above methods. Combining the speed and correctness of Parcelable with the simplicity of a Bundle:

@Override
public Parcelable onSaveInstanceState() {
    Bundle bundle = new Bundle();
    // The vars you want to save - in this instance a string and a boolean
    String someString = "something";
    boolean someBoolean = true;
    State state = new State(super.onSaveInstanceState(), someString, someBoolean);
    bundle.putParcelable(State.STATE, state);
    return bundle;
}

@Override
public void onRestoreInstanceState(Parcelable state) {
    if (state instanceof Bundle) {
        Bundle bundle = (Bundle) state;
        State customViewState = (State) bundle.getParcelable(State.STATE);
        // The vars you saved - do whatever you want with them
        String someString = customViewState.getText();
        boolean someBoolean = customViewState.isSomethingShowing());
        super.onRestoreInstanceState(customViewState.getSuperState());
        return;
    }
    // Stops a bug with the wrong state being passed to the super
    super.onRestoreInstanceState(BaseSavedState.EMPTY_STATE); 
}

protected static class State extends BaseSavedState {
    protected static final String STATE = "YourCustomView.STATE";

    private final String someText;
    private final boolean somethingShowing;

    public State(Parcelable superState, String someText, boolean somethingShowing) {
        super(superState);
        this.someText = someText;
        this.somethingShowing = somethingShowing;
    }

    public String getText(){
        return this.someText;
    }

    public boolean isSomethingShowing(){
        return this.somethingShowing;
    }
}

In a project, I actually have some heading fixed to the bottom of the screen on page load (it's a drawing app so the heading is at the bottom to give maximum space to the canvas element on wide viewport).

I needed the heading to become 'absolute' when it reaches the footer on scroll, since I don't want the heading over the footer (heading colour is same as footer background colour).

I took the oldest response on here (edited by Gearge Millo) and that code snippet worked for my use-case. With some playing around I got this working. Now the fixed heading sits beautifully above the footer once it reaches the footer.

Just thought I'd share my use-case and how it worked, and say thank you! The app: http://joefalconer.com/web_projects/drawingapp/index.html

    /* CSS */
    @media screen and (min-width: 1100px) {
        #heading {
            height: 80px;
            width: 100%;
            position: absolute;  /* heading is 'absolute' on page load. DOESN'T WORK if I have this on 'fixed' */
            bottom: 0;
        }
    }

    // jQuery
    // Stop the fixed heading from scrolling over the footer
    $.fn.followTo = function (pos) {
      var $this = this,
      $window = $(window);

      $window.scroll(function (e) {
        if ($window.scrollTop() > pos) {
          $this.css( { position: 'absolute', bottom: '-180px' } );
        } else {
          $this.css( { position: 'fixed', bottom: '0' } );
        }
      });
    };
    // This behaviour is only needed for wide view ports
    if ( $('#heading').css("position") === "absolute" ) {
      $('#heading').followTo(180);
    }

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

@jasonk - if you want to have "or" then negate all conditions since (A and B) <=> ~(~A or ~B)

but if you have values other than boolean try using type converters:

<MultiDataTrigger.Conditions>
    <Condition Value="True">
        <Condition.Binding>
            <MultiBinding Converter="{StaticResource conditionConverter}">
                <Binding Path="Name" />
                <Binding Path="State" />
            </MultiBinding>
        </Condition.Binding>
        <Setter Property="Background" Value="Cyan" />
    </Condition>
</MultiDataTrigger.Conditions>

you can use the values in Convert method any way you like to produce a condition which suits you.

In Laravel 4 & 5 (up to 5.7), you can use str_limit, which limits the number of characters in a string.

While in Laravel 5.8 up, you can use the Str::limit helper.

//For Laravel 4 to Laravel 5.5
{{ str_limit($string, $limit = 150, $end = '...') }}
//For Laravel 5.5 upwards
{{ \Illuminate\Support\Str::limit($string, 150, $end='...') }}

Using aggregate is the right approach, but you need to $unwind the list array before applying the $match so that you can filter individual elements and then use $group to put it back together:

db.test.aggregate([
    { $match: {_id: ObjectId("512e28984815cbfcb21646a7")}},
    { $unwind: '$list'},
    { $match: {'list.a': {$gt: 3}}},
    { $group: {_id: '$_id', list: {$push: '$list.a'}}}
])

outputs:

{
  "result": [
    {
      "_id": ObjectId("512e28984815cbfcb21646a7"),
      "list": [
        4,
        5
      ]
    }
  ],
  "ok": 1
}

MongoDB 3.2 Update

Starting with the 3.2 release, you can use the new $filter aggregation operator to do this more efficiently by only including the list elements you want during a $project:

db.test.aggregate([
    { $match: {_id: ObjectId("512e28984815cbfcb21646a7")}},
    { $project: {
        list: {$filter: {
            input: '$list',
            as: 'item',
            cond: {$gt: ['$$item.a', 3]}
        }}
    }}
])

upgrading pip worked for me

python -m pip install --upgrade pip

Ok got this as:

var query = (from t in Transactions
             group t by new {t.MaterialID, t.ProductID}
             into grp
                    select new
                    {
                        grp.Key.MaterialID,
                        grp.Key.ProductID,
                        Quantity = grp.Sum(t => t.Quantity)
                    }).ToList();

MSI is basically an installer from Microsoft that is built into windows. It associates components with features and contains installation control information. It is not necessary that this file contains actual user required files i.e the application programs which user expects. MSI can contain another setup.exe inside it which the MSI wraps, which actually contains the user required files.

Hope this clears you doubt.

Ok here is what I do

sys.argv is always what you type into the terminal or use as the file path when executing it with python.exe or pythonw.exe

For example you can run the file text.py several ways, they each give you a different answer they always give you the path that python was typed.

    C:\Documents and Settings\Admin>python test.py
    sys.argv[0]: test.py
    C:\Documents and Settings\Admin>python "C:\Documents and Settings\Admin\test.py"
    sys.argv[0]: C:\Documents and Settings\Admin\test.py

Ok so know you can get the file name, great big deal, now to get the application directory you can know use os.path, specifically abspath and dirname

    import sys, os
    print os.path.dirname(os.path.abspath(sys.argv[0]))

That will output this:

   C:\Documents and Settings\Admin\

it will always output this no matter if you type python test.py or python "C:\Documents and Settings\Admin\test.py"

The problem with using __file__ Consider these two files test.py

import sys
import os

def paths():
        print "__file__: %s" % __file__
        print "sys.argv: %s" % sys.argv[0]

        a_f = os.path.abspath(__file__)
        a_s = os.path.abspath(sys.argv[0])

        print "abs __file__: %s" % a_f
        print "abs sys.argv: %s" % a_s

if __name__ == "__main__":
    paths()

import_test.py

import test
import sys

test.paths()

print "--------"
print __file__
print sys.argv[0]

Output of "python test.py"

C:\Documents and Settings\Admin>python test.py
__file__: test.py
sys.argv: test.py
abs __file__: C:\Documents and Settings\Admin\test.py
abs sys.argv: C:\Documents and Settings\Admin\test.py

Output of "python test_import.py"

C:\Documents and Settings\Admin>python test_import.py
__file__: C:\Documents and Settings\Admin\test.pyc
sys.argv: test_import.py
abs __file__: C:\Documents and Settings\Admin\test.pyc
abs sys.argv: C:\Documents and Settings\Admin\test_import.py
--------
test_import.py
test_import.py

So as you can see file gives you always the python file it is being run from, where as sys.argv[0] gives you the file that you ran from the interpreter always. Depending on your needs you will need to choose which one best fits your needs.

You don't need --header "Content-Length: $LENGTH".

curl --request POST --data-binary "@template_entry.xml" $URL

Note that GET request does not support content body widely.

Also remember that POST request have 2 different coding schema. This is first form:

  $ nc -l -p 6666 &
  $ curl  --request POST --data-binary "@README" http://localhost:6666

POST / HTTP/1.1
User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6

You probably request this:

-F/--form name=content
           (HTTP) This lets curl emulate a filled-in form in
              which a user has pressed the submit button. This
              causes curl to POST data using the Content- Type
              multipart/form-data according to RFC2388. This
              enables uploading of binary files etc. To force the
              'content' part to be a file, prefix the file name
              with an @ sign. To just get the content part from a
              file, prefix the file name with the symbol <. The
              difference between @ and < is then that @ makes a
              file get attached in the post as a file upload,
              while the < makes a text field and just get the
              contents for that text field from a file.

In python 2 you can do it with: raw_input()

>>print("Hello World!")    
>>raw_input('Waiting a key...')

In python 3 you can do it with: input()

>>print("Hello world!")    
>>input('Waiting a key...')

Also, you can do it with the time.sleep(time)

>>import time
>>print("The program will close in 5 seconds")
>>time.sleep(5)

I'm using an MVC / MVA design pattern, with multiple types of "views". One type is a "GuiView", which is a Tk window. I pass a view reference to my window object which does things like link buttons back to view functions (which the adapter / controller class also calls).

In order to do that, the view object constructor needed to be completed prior to creating the window object. After creating and displaying the window, I wanted to do some initial tasks with the view automatically. At first I tried doing them post mainloop(), but that didn't work because mainloop() blocked!

As such, I created the window object and used tk.update() to draw it. Then, I kicked off my initial tasks, and finally started the mainloop.

import Tkinter as tk

class Window(tk.Frame):
    def __init__(self, master=None, view=None ):
        tk.Frame.__init__( self, master )
        self.view_ = view       
        """ Setup window linking it to the view... """

class GuiView( MyViewSuperClass ):

    def open( self ):
        self.tkRoot_ = tk.Tk()
        self.window_ = Window( master=None, view=self )
        self.window_.pack()
        self.refresh()
        self.onOpen()
        self.tkRoot_.mainloop()         

    def onOpen( self ):        
        """ Do some initial tasks... """

    def refresh( self ):        
        self.tkRoot_.update()

If you really need to specify all the .jar files dynamically you could use shell scripts, or Apache Ant. There's a commons project called Commons Launcher which basically lets you specify your startup script as an ant build file (if you see what I mean).

Then, you can specify something like:

<path id="base.class.path">
    <pathelement path="${resources.dir}"/>
    <fileset dir="${extensions.dir}" includes="*.jar" />
    <fileset dir="${lib.dir}" includes="*.jar"/>
</path>

In your launch build file, which will launch your application with the correct classpath.

With performance penalty and if you need todo it only in SQL you can use the FORMAT function and 3 REPLACE : After the format replace the . with another char for example @, then replace the , with a . and then the chararacter you choose by a , which lead you for your example to 1.111,00

SELECT REPLACE(REPLACE(REPLACE(FORMAT("1111.00", 2), ".", "@"), ",", "."), "@", ",")

It's pretty much the same as running a query. In your original code you are creating a command object, putting it in the cmd variable, and never use it. Here, however, you will use that instead of da.InsertCommand.

Also, use a using for all disposable objects, so that you are sure that they are disposed properly:

private void button1_Click(object sender, EventArgs e) {
  using (SqlConnection con = new SqlConnection(dc.Con)) {
    using (SqlCommand cmd = new SqlCommand("sp_Add_contact", con)) {
      cmd.CommandType = CommandType.StoredProcedure;

      cmd.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = txtFirstName.Text;
      cmd.Parameters.Add("@LastName", SqlDbType.VarChar).Value = txtLastName.Text;

      con.Open();
      cmd.ExecuteNonQuery();
    }
  }
}

Have you tried with the custom format "#,##0.##" ?

Maybe can help to check that the path to the xsd file has not 'strange' characters like 'é', or similar: I was having the same issue but when I changed to a path without the 'é' the error dissapeared.

I'm recombinging the ideas of some other answers here and this answer on another thread into a Try-style extension method. This has a benefit if you want an extension method, yet avoiding an exception upon timeout.

public static async Task<bool> TryWithTimeoutAfter<TResult>(this Task<TResult> task,
    TimeSpan timeout, Action<TResult> successor)
{

    using var timeoutCancellationTokenSource = new CancellationTokenSource();
    var completedTask = await Task.WhenAny(task, Task.Delay(timeout, timeoutCancellationTokenSource.Token))
                                  .ConfigureAwait(continueOnCapturedContext: false);

    if (completedTask == task)
    {
        timeoutCancellationTokenSource.Cancel();

        // propagate exception rather than AggregateException, if calling task.Result.
        var result = await task.ConfigureAwait(continueOnCapturedContext: false);
        successor(result);
        return true;
    }
    else return false;        
}     

async Task Example(Task<string> task)
{
    string result = null;
    if (await task.TryWithTimeoutAfter(TimeSpan.FromSeconds(1), r => result = r))
    {
        Console.WriteLine(result);
    }
}

date() itself is only for formatting, but it accepts a second parameter.

date("F j, Y", time() - 60 * 60 * 24);

To keep it simple I just subtract 24 hours from the unix timestamp.

A modern oop-approach is using DateTime

$date = new DateTime();
$date->sub(new DateInterval('P1D'));
echo $date->format('F j, Y') . "\n";

Or in your case (more readable/obvious)

$date = new DateTime();
$date->add(DateInterval::createFromDateString('yesterday'));
echo $date->format('F j, Y') . "\n";

(Because DateInterval is negative here, we must add() it here)

As replacing "\n" with "" doesn't give you the result that you want, that means that what you should replace is actually not "\n", but some other character combination.

One possibility is that what you should replace is the "\r\n" character combination, which is the newline code in a Windows system. If you replace only the "\n" (line feed) character it will leave the "\r" (carriage return) character, which still may be interpreted as a line break, depending on how you display the string.

If the source of the string is system specific you should use that specific string, otherwise you should use Environment.NewLine to get the newline character combination for the current system.

string temp = mystring.Replace("\r\n", string.Empty);

or:

string temp = mystring.Replace(Environment.NewLine, string.Empty);

Usually $ ipython notebook will launch the notebooks and kernels at he current working directory of the terminal.

But if you want to specify the launch directory, you can use --notebook-dir option as follows:

$ ipython notebook --notebook-dir=/path/to/specific/directory

If checkout master was the last thing you did, then the reflog entry HEAD@{1} will contain your commits (otherwise use git reflog or git log -p to find them). Use git merge HEAD@{1} to fast forward them into master.

EDIT:

As noted in the comments, Git Ready has a great article on this.

git reflog and git reflog --all will give you the commit hashes of the mis-placed commits.

Source: http://gitready.com/intermediate/2009/02/09/reflog-your-safety-net.html

Two possibilities. Either use a combined key:

class MyKey {
    int firstIndex;
    int secondIndex;
    // important: override hashCode() and equals()
}

Or a Map of Map:

Map<Integer, Map<Integer, Integer>> myMap;

Swift 4:

In the view controller you want to hide the navigation bar from.

override func viewWillAppear(_ animated: Bool) {
    self.navigationController?.setNavigationBarHidden(true, animated: animated)
    super.viewWillAppear(animated)
}

override func viewWillDisappear(_ animated: Bool) {
    self.navigationController?.setNavigationBarHidden(false, animated: animated)
    super.viewWillDisappear(animated)
}

I would recommend using PATCH, because your resource 'group' has many properties but in this case, you are updating only the activation field(partial modification)

according to the RFC5789 (https://tools.ietf.org/html/rfc5789)

The existing HTTP PUT method only allows a complete replacement of a document. This proposal adds a new HTTP method, PATCH, to modify an existing HTTP resource.

Also, in more details,

The difference between the PUT and PATCH requests is reflected in the way the server processes the enclosed entity to modify the resource
identified by the Request-URI. In a PUT request, the enclosed entity is considered to be a modified version of the resource stored on the
origin server, and the client is requesting that the stored version
be replaced. With PATCH, however, the enclosed entity contains a set of instructions describing how a resource currently residing on the
origin server should be modified to produce a new version. The PATCH method affects the resource identified by the Request-URI, and it
also MAY have side effects on other resources; i.e., new resources
may be created, or existing ones modified, by the application of a
PATCH.

PATCH is neither safe nor idempotent as defined by [RFC2616], Section 9.1.

Clients need to choose when to use PATCH rather than PUT. For
example, if the patch document size is larger than the size of the
new resource data that would be used in a PUT, then it might make
sense to use PUT instead of PATCH. A comparison to POST is even more difficult, because POST is used in widely varying ways and can
encompass PUT and PATCH-like operations if the server chooses. If
the operation does not modify the resource identified by the Request- URI in a predictable way, POST should be considered instead of PATCH
or PUT.

The response code for PATCH is

The 204 response code is used because the response does not carry a message body (which a response with the 200 code would have). Note that other success codes could be used as well.

also refer thttp://restcookbook.com/HTTP%20Methods/patch/

Caveat: An API implementing PATCH must patch atomically. It MUST not be possible that resources are half-patched when requested by a GET.

Best guess is you are on windows and your line ending settings are set for windows. See this topic: How to change line-ending settings

or use:

tr '\r\n' ' '

Example using std::vector

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

int main()
{
    /// Initilaize vector using intitializer list ( requires C++11 )
    std::vector<std::string> names = {"john", "bobby", "dear", "test1", "catherine", "nomi", "shinta", "martin", "abe", "may", "zeno", "zack", "angeal", "gabby"};

    // Sort names using std::sort
    std::sort(names.begin(), names.end() );

    // Print using range-based and const auto& for ( both requires C++11 )
    for(const auto& currentName : names)
    {
        std::cout << currentName << std::endl;
    }

    //... or by using your orignal for loop ( vector support [] the same way as plain arrays )
    for(int y = 0; y < names.size(); y++)
    {
       std:: cout << names[y] << std::endl; // you were outputting name[z], but only increasing y, thereby only outputting element z ( 14 )
    }
    return 0;

}

http://ideone.com/Q9Ew2l

This completely avoids using plain arrays, and lets you use the std::sort function. You might need to update you compiler to use the = {...} You can instead add them by using vector.push_back("name")

Your "application/xrds+xml" was giving me issues, I was receiving a Content-Length of 0 (no response).

After removing that, you can access the response using response.GetResponseStream().

HttpWebRequest request = WebRequest.Create("http://google.com") as HttpWebRequest;

//request.Accept = "application/xrds+xml";  
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

WebHeaderCollection header = response.Headers;

var encoding = ASCIIEncoding.ASCII;
using (var reader = new System.IO.StreamReader(response.GetResponseStream(), encoding))
{
    string responseText = reader.ReadToEnd();
}

Try This, Mine worked this way. To get any data of tag just replace the "a" with the tag you want.

from bs4 import BeautifulSoup as bs
import urllib

url="http://currentaffairs.gktoday.in/month/current-affairs-january-2015"

soup = bs(urllib.urlopen(url))
for link in soup.findAll('a'):
        print link.string

Don't check. Go ahead and assume that it is the right input, and catch an exception if it isn't.

intresult = None
while intresult is None:
    input = raw_input()
    try: intresult = int(input)
    except ValueError: pass

Take a look at Job Control on UNIX systems

If you don't have control of your shell, simply hitting ctrl + C should stop the process. If that doesn't work, you can try ctrl + Z and using the jobs and kill -9 %<job #> to kill it. The '-9' is a type of signal. You can man kill to see a list of signals.

If your cascading deletes nuke a product because it was a member of a category that was killed, then you've set up your foreign keys improperly. Given your example tables, you should have the following table setup:

CREATE TABLE categories (
    id int unsigned not null primary key,
    name VARCHAR(255) default null
)Engine=InnoDB;

CREATE TABLE products (
    id int unsigned not null primary key,
    name VARCHAR(255) default null
)Engine=InnoDB;

CREATE TABLE categories_products (
    category_id int unsigned not null,
    product_id int unsigned not null,
    PRIMARY KEY (category_id, product_id),
    KEY pkey (product_id),
    FOREIGN KEY (category_id) REFERENCES categories (id)
       ON DELETE CASCADE
       ON UPDATE CASCADE,
    FOREIGN KEY (product_id) REFERENCES products (id)
       ON DELETE CASCADE
       ON UPDATE CASCADE
)Engine=InnoDB;

This way, you can delete a product OR a category, and only the associated records in categories_products will die alongside. The cascade won't travel farther up the tree and delete the parent product/category table.

e.g.

products: boots, mittens, hats, coats
categories: red, green, blue, white, black

prod/cats: red boots, green mittens, red coats, black hats

If you delete the 'red' category, then only the 'red' entry in the categories table dies, as well as the two entries prod/cats: 'red boots' and 'red coats'.

The delete will not cascade any farther and will not take out the 'boots' and 'coats' categories.

comment followup:

you're still misunderstanding how cascaded deletes work. They only affect the tables in which the "on delete cascade" is defined. In this case, the cascade is set in the "categories_products" table. If you delete the 'red' category, the only records that will cascade delete in categories_products are those where category_id = red. It won't touch any records where 'category_id = blue', and it would not travel onwards to the "products" table, because there's no foreign key defined in that table.

Here's a more concrete example:

categories:     products:
+----+------+   +----+---------+
| id | name |   | id | name    |
+----+------+   +----+---------+
| 1  | red  |   | 1  | mittens |
| 2  | blue |   | 2  | boots   |
+---++------+   +----+---------+

products_categories:
+------------+-------------+
| product_id | category_id |
+------------+-------------+
| 1          | 1           | // red mittens
| 1          | 2           | // blue mittens
| 2          | 1           | // red boots
| 2          | 2           | // blue boots
+------------+-------------+

Let's say you delete category #2 (blue):

DELETE FROM categories WHERE (id = 2);

the DBMS will look at all the tables which have a foreign key pointing at the 'categories' table, and delete the records where the matching id is 2. Since we only defined the foreign key relationship in products_categories, you end up with this table once the delete completes:

+------------+-------------+
| product_id | category_id |
+------------+-------------+
| 1          | 1           | // red mittens
| 2          | 1           | // red boots
+------------+-------------+

There's no foreign key defined in the products table, so the cascade will not work there, so you've still got boots and mittens listed. There's just no 'blue boots' and no 'blue mittens' anymore.

The "Usort" function is your answer.

Generally speaking, you should not put anything into META-INF yourself. Instead, you should rely upon whatever you use to package up your JAR. This is one of the areas where I think Ant really excels: specifying JAR file manifest attributes. It's very easy to say something like:

<jar ...>
    <manifest>
        <attribute name="Main-Class" value="MyApplication"/>
    </manifest>
</jar>

At least, I think that's easy... :-)

The point is that META-INF should be considered an internal Java meta directory. Don't mess with it! Any files you want to include with your JAR should be placed in some other sub-directory or at the root of the JAR itself.

It should be like this

$(this).text($(this).text().replace('N/A, ', ''))

To do it for your whole collection you can also use a loop (based on Niels example):

db.status.find().forEach(function(doc){ 
    doc._id=doc.UserId; db.status_new.insert(doc);
});
db.status_new.renameCollection("status", true);

In this case UserId was the new ID I wanted to use

Here's a code excerpt we're using in our app to set request headers. You'll note we set the CONTENT_TYPE header only on a POST or PUT, but the general method of adding headers (via a request interceptor) is used for GET as well.

/**
 * HTTP request types
 */
public static final int POST_TYPE   = 1;
public static final int GET_TYPE    = 2;
public static final int PUT_TYPE    = 3;
public static final int DELETE_TYPE = 4;

/**
 * HTTP request header constants
 */
public static final String CONTENT_TYPE         = "Content-Type";
public static final String ACCEPT_ENCODING      = "Accept-Encoding";
public static final String CONTENT_ENCODING     = "Content-Encoding";
public static final String ENCODING_GZIP        = "gzip";
public static final String MIME_FORM_ENCODED    = "application/x-www-form-urlencoded";
public static final String MIME_TEXT_PLAIN      = "text/plain";

private InputStream performRequest(final String contentType, final String url, final String user, final String pass,
    final Map<String, String> headers, final Map<String, String> params, final int requestType) 
            throws IOException {

    DefaultHttpClient client = HTTPClientFactory.newClient();

    client.getParams().setParameter(HttpProtocolParams.USER_AGENT, mUserAgent);

    // add user and pass to client credentials if present
    if ((user != null) && (pass != null)) {
        client.getCredentialsProvider().setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(user, pass));
    }

    // process headers using request interceptor
    final Map<String, String> sendHeaders = new HashMap<String, String>();
    if ((headers != null) && (headers.size() > 0)) {
        sendHeaders.putAll(headers);
    }
    if (requestType == HTTPRequestHelper.POST_TYPE || requestType == HTTPRequestHelper.PUT_TYPE ) {
        sendHeaders.put(HTTPRequestHelper.CONTENT_TYPE, contentType);
    }
    // request gzip encoding for response
    sendHeaders.put(HTTPRequestHelper.ACCEPT_ENCODING, HTTPRequestHelper.ENCODING_GZIP);

    if (sendHeaders.size() > 0) {
        client.addRequestInterceptor(new HttpRequestInterceptor() {

            public void process(final HttpRequest request, final HttpContext context) throws HttpException,
                IOException {
                for (String key : sendHeaders.keySet()) {
                    if (!request.containsHeader(key)) {
                        request.addHeader(key, sendHeaders.get(key));
                    }
                }
            }
        });
    }

}

You can also install json-py from here http://sourceforge.net/projects/json-py/

Do this:

from threading import Thread

def func1():
    print('Working')

def func2():
    print("Working")

if __name__ == '__main__':
    Thread(target = func1).start()
    Thread(target = func2).start()

You can use like this :

$(":checkbox:not(:checked)")

You've simply got it backwards. Specifying a minimum width would make the select menu always be at least that width, so it will continue expanding to 90% no matter what the window size is, also being at least the size of its longest option.

You need to use max-width instead. This way, it will let the select menu expand to its longest option, but if that expands past your set maximum of 90% width, crunch it down to that width.

I had the same problem, and it came from a wrong client_id / Facebook App ID.

Did you switch your Facebook app to "public" or "online ? When you do so, Facebook creates a new app with a new App ID.

You can compare the "client_id" parameter value in the url with the one in your Facebook dashboard.

Also Make sure your app is public. Click on + Add product Now go to products => Facebook Login Now do the following:

Valid OAuth redirect URIs : example.com/

The only way to add any book marks in MobileSafari (including ones on the home screen) is with the builtin UI, and that Apples does not provide anyway to do this from scripts within a page. In fact, I am pretty sure there is no mechanism for doing this on the desktop version of Safari either.

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

In modern browsers, you can accomplish this with string.matchAll().

The benefit to this approach vs RegExp.exec() is that it does not rely on the regex being stateful, as in @Gumbo's answer.

let regexp = /bar/g;
let str = 'foobarfoobar';

let matches = [...str.matchAll(regexp)];
matches.forEach((match) => {
    console.log("match found at " + match.index);
});

I wanted something that was more directly usable without organization-specific hard-coded string values in it. I offer the following as a directly reusable chunk of code. The minor downside is needing to determine and pass the working folder when making the call.

public static void ExecuteCommand(string command, string workingFolder)
        {
            int ExitCode;
            ProcessStartInfo ProcessInfo;
            Process process;

            ProcessInfo = new ProcessStartInfo("cmd.exe", "/c " + command);
            ProcessInfo.CreateNoWindow = true;
            ProcessInfo.UseShellExecute = false;
            ProcessInfo.WorkingDirectory = workingFolder;
            // *** Redirect the output ***
            ProcessInfo.RedirectStandardError = true;
            ProcessInfo.RedirectStandardOutput = true;

            process = Process.Start(ProcessInfo);
            process.WaitForExit();

            // *** Read the streams ***
            string output = process.StandardOutput.ReadToEnd();
            string error = process.StandardError.ReadToEnd();

            ExitCode = process.ExitCode;

            MessageBox.Show("output>>" + (String.IsNullOrEmpty(output) ? "(none)" : output));
            MessageBox.Show("error>>" + (String.IsNullOrEmpty(error) ? "(none)" : error));
            MessageBox.Show("ExitCode: " + ExitCode.ToString(), "ExecuteCommand");
            process.Close();
        }

Called like this:

    // This will get the current WORKING directory (i.e. \bin\Debug)
    string workingDirectory = Environment.CurrentDirectory;
    // This will get the current PROJECT directory
    string projectDirectory = Directory.GetParent(workingDirectory).Parent.FullName;
    string commandToExecute = Path.Combine(projectDirectory, "TestSetup", "WreckersTestSetupQA.bat");
    string workingFolder = Path.GetDirectoryName(commandToExecute);
    commandToExecute = QuotesAround(commandToExecute);
    ExecuteCommand(commandToExecute, workingFolder);

In this example, from within Visual Studio 2017, as part of a test run, I want to run an environment reset batch file before executing some tests. (SpecFlow+xUnit). I got tired of extra steps for manually running the bat file separately, and wanted to just run the bat file as part of the C# test setup code. The environment reset batch file moves test case files back into the input folder, cleans up output folders, etc. to get to the proper test starting state for testing. The QuotesAround method simply puts quotes around the command line in case there are spaces in folder names ("Program Files", anyone?). All that's in it is this: private string QuotesAround(string input) {return "\"" + input + "\"";}

Hope some find this useful and save a few minutes if your scenario is similar to mine.

The DELIMITER statement changes the standard delimiter which is semicolon ( ;) to another. The delimiter is changed from the semicolon( ;) to double-slashes //.

Why do we have to change the delimiter?

Because we want to pass the stored procedure, custom functions etc. to the server as a whole rather than letting mysql tool to interpret each statement at a time.

You can provide password as parameter to expect script.

start cmd.exe 

opens a separate window

start file.cmd 

opens the batch file and executes it in another command prompt

sed -i.bak "s#https.*\.com#$pub_url#g" MyHTMLFile.html

If you have a link to be added, try this. Search for the URL as above (starting with https and ending with.com here) and replace it with a URL string. I have used a variable $pub_url here. s here means search and g means global replacement.

It works !

If you're using jackson, better to convert directly to ObjectNode.

//not including SerializationFeatures for brevity
static final ObjectMapper mapper = new ObjectMapper();

//pass it your payload
public static ObjectNode convObjToONode(Object o) {
    StringWriter stringify = new StringWriter();
    ObjectNode objToONode = null;

    try {
        mapper.writeValue(stringify, o);
        objToONode = (ObjectNode) mapper.readTree(stringify.toString());
    } catch (IOException e) {
        e.printStackTrace();
    }

    System.out.println(objToONode);
    return objToONode;
}

myString.split('-').splice(1).join('-')

Sure, a Linked List is a bit confusing for programming n00bs, pretty much the temptation is to look at it as Russian Dolls, because that's what it seems like, a LinkedList Object in a LinkedList Object. But that's a touch difficult to visualize, instead look at it like a computer.

LinkedList = Data + Next Member

Where it's the last member of the list if next is NULL

So a 5 member LinkedList would be:

LinkedList(Data1, LinkedList(Data2, LinkedList(Data3, LinkedList(Data4, LinkedList(Data5, NULL)))))

But you can think of it as simply:

Data1 -> Data2 -> Data3 -> Data4 -> Data5 -> NULL

So, how do we find the end of this? Well, we know that the NULL is the end so:

public void append(LinkedList myNextNode) {
  LinkedList current = this; //Make a variable to store a pointer to this LinkedList
  while (current.next != NULL) { //While we're not at the last node of the LinkedList
    current = current.next; //Go further down the rabbit hole.
  }
  current.next = myNextNode; //Now we're at the end, so simply replace the NULL with another Linked List!
  return; //and we're done!
}

This is very simple code of course, and it will infinitely loop if you feed it a circularly linked list! But that's the basics.

user: USER

this.user = ({} as USER)

Your can do it like this in short hands.

        int[,] values=new int[2,3]{{2,4,5},{4,5,2}};

        for (int i = 0; i < values.GetLength(0); i++)
        {
            for (int k = 0; k < values.GetLength(1); k++) {
                Console.Write(values[i,k]);
            }

            Console.WriteLine();
        }

Since the built-in IndexOf function is already optimized for searching a character within a string, an even faster version would be (as extension method):

public static int NthIndexOf(this string input, char value, int n)
{
    if (n <= 0) throw new ArgumentOutOfRangeException("n", n, "n is less than zero.");

    int i = -1;
    do
    {
        i = input.IndexOf(value, i + 1);
        n--;
    }
    while (i != -1 && n > 0);

    return i;
}

Or to search from the end of the string using LastIndexOf:

public static int NthLastIndexOf(this string input, char value, int n)
{
    if (n <= 0) throw new ArgumentOutOfRangeException("n", n, "n is less than zero.");

    int i = input.Length;
    do
    {
        i = input.LastIndexOf(value, i - 1);
        n--;
    }
    while (i != -1 && n > 0);

    return i;
}

Searching for a string instead of a character is as simple as changing the parameter type from char to string and optionally add an overload to specify the StringComparison.

I can sympathise... having once been in a similar predicament, though I did at least have some background. I concur with @ShawnMilo regarding Head Fist Java. Also recommend Sams Teach Yourself Java in 21 Days and, given that you say you have no programming background, I strongly urge you to look at The Oject Oriented Thought Process by Matt Weisfeld. I also concur with all the people on this thread who say that there's WAY more to programming than 'simply' learning one language (especially if it's Java). Having said that, good luck and god speed.

PS I'd +1 @Patrick McDonald for sense of humour, but I don't have enough rep!

PPS And another virtual +1 for @Robin. I was wondering when the Four Yorkshiremen would get in on this thread...

In C++ the requirements imposed on default arguments with regard to their location in parameter list are as follows:

1. Default argument for a given parameter has to be specified no more than once. Specifying it more than once (even with the same default value) is illegal.

2. Parameters with default arguments have to form a contiguous group at the end of the parameter list.

Now, keeping that in mind, in C++ you are allowed to "grow" the set of parameters that have default arguments from one declaration of the function to the next, as long as the above requirements are continuously satisfied.

For example, you can declare a function with no default arguments

void foo(int a, int b);

In order to call that function after such declaration you'll have to specify both arguments explicitly.

Later (further down) in the same translation unit, you can re-declare it again, but this time with one default argument

void foo(int a, int b = 5);

and from this point on you can call it with just one explicit argument.

Further down you can re-declare it yet again adding one more default argument

void foo(int a = 1, int b);

and from this point on you can call it with no explicit arguments.

The full example might look as follows

void foo(int a, int b);

int main()
{
  foo(2, 3);

  void foo(int a, int b = 5); // redeclare
  foo(8); // OK, calls `foo(8, 5)`

  void foo(int a = 1, int b); // redeclare again
  foo(); // OK, calls `foo(1, 5)`
}

void foo(int a, int b)
{
  // ...
}

As for the code in your question, both variants are perfectly valid, but they mean different things. The first variant declares a default argument for the second parameter right away. The second variant initially declares your function with no default arguments and then adds one for the second parameter.

The net effect of both of your declarations (i.e. the way it is seen by the code that follows the second declaration) is exactly the same: the function has default argument for its second parameter. However, if you manage to squeeze some code between the first and the second declarations, these two variants will behave differently. In the second variant the function has no default arguments between the declarations, so you'll have to specify both arguments explicitly.

Below code does the work for converting ms to min:secs with [m:ss] format

int seconds;
int minutes;
String Sec;
long Mills = ...;  // Milliseconds goes here
minutes = (int)(Mills / 1000)  / 60;
seconds = (int)((Mills / 1000) % 60);
Sec = seconds+"";

TextView.setText(minutes+":"+Sec);//Display duration [3:40]

Worked for me

<script type="text/javascript">


 if (typeof window.event != 'undefined')
    document.onkeydown = function()
    {
        if (event.srcElement.tagName.toUpperCase() != 'INPUT')
            return (event.keyCode != 8);
    }
else
    document.onkeypress = function(e)
    {
        if (e.target.nodeName.toUpperCase() != 'INPUT')
            return (e.keyCode != 8);
    }

</script>

Great question, and it's odd that the Swing toolkit doesn't include this functionality natively for JTextFields. But, here's a great answer from my Udemy.com course "Learn Java Like a Kid":

txtGuess = new JTextField();
txtGuess.addKeyListener(new KeyAdapter() {
    public void keyTyped(KeyEvent e) { 
        if (txtGuess.getText().length() >= 3 ) // limit textfield to 3 characters
            e.consume(); 
    }  
});

This limits the number of characters in a guessing game text field to 3 characters, by overriding the keyTyped event and checking to see if the textfield already has 3 characters - if so, you're "consuming" the key event (e) so that it doesn't get processed like normal.

From the numpy fft page http://docs.scipy.org/doc/numpy/reference/routines.fft.html:

When the input a is a time-domain signal and A = fft(a), np.abs(A) is its amplitude spectrum and np.abs(A)**2 is its power spectrum. The phase spectrum is obtained by np.angle(A).

Just in case, if someone is looking for a similar problem...

Most solutions given here are one line and are quite readable and simple. Just wanted to add one more that does not need the use of lambda(I am assuming that you are trying to use lambda just for the sake of making it a one line code). Instead, you can use a simple list comprehension.

[print(i) for i in x]

BTW, the return values will be a list on None s.

You cannot access var with the generic.

Try something like

Console.WriteLine("Generic : {0}", test);

MORE
I try to make the slide animation like iOS animation when present a View Model (like this https://www.youtube.com/watch?v=deZobvh2064) but failed.

Looking at iOS present animation you will see: The animation from bottom with alpha (about 50%) then it go very fast then slower, the animation time is about > 500ms (I use trim video tools for count the animation time https://www.kapwing.com/trim-video so it can not exactly 100%)

Then I try to apply to android.
To make alpha I use <alpha> and success.
To make animation start faster than slower I use android:interpolator="a decelerate interpolator" but it almost failed.

There are 3 default decelerate interpolator in Android
@android:interpolator/decelerate_quad -> factor = 1
@android:interpolator/decelerate_cubic -> factor = 1.5
@android:interpolator/decelerate_quint _> factor = 2.5
(higher factor <=> animation start more faster from start and more slower at end)
Here is a good tutorial http://cogitolearning.co.uk/2013/10/android-animations-tutorial-5-more-on-interpolators/ for understand it

I tried 3 above I can not achieve like iOS, the animation can not start faster like iOS. Then I create a custom decelerateInterpolator wiht factor = 3 like

<?xml version="1.0" encoding="utf-8"?>
<decelerateInterpolator xmlns:android="http://schemas.android.com/apk/res/android"
    android:factor="3" />

and I increase the duration time from 500 -> 750. It working well (very similar to iOS). However, it only working well in some device, in some device the animation is quite slow. Later on, I know that animation may different on different device (eg: some device will faster and some device will slower) so I can not make it the animation similar in all Android device. Therefore I don't use interpolator. I don't know if my testing is exactly 100% or not but I hope this experience help

This could also happens if you put a @PreAuthorize or @PostAuthorize in a Bean in creation. I would recommend to move such annotations to methods of interest.

WITH    q AS 
        (
        SELECT  *
        FROM    mytable
        WHERE   ParentID IS NULL -- this condition defines the ultimate ancestors in your chain, change it as appropriate
        UNION ALL
        SELECT  m.*
        FROM    mytable m
        JOIN    q
        ON      m.parentID = q.PersonID
        )
SELECT  *
FROM    q

By adding the ordering condition, you can preserve the tree order:

WITH    q AS 
        (
        SELECT  m.*, CAST(ROW_NUMBER() OVER (ORDER BY m.PersonId) AS VARCHAR(MAX)) COLLATE Latin1_General_BIN AS bc
        FROM    mytable m
        WHERE   ParentID IS NULL
        UNION ALL
        SELECT  m.*,  q.bc + '.' + CAST(ROW_NUMBER() OVER (PARTITION BY m.ParentID ORDER BY m.PersonID) AS VARCHAR(MAX)) COLLATE Latin1_General_BIN
        FROM    mytable m
        JOIN    q
        ON      m.parentID = q.PersonID
        )
SELECT  *
FROM    q
ORDER BY
        bc

By changing the ORDER BY condition you can change the ordering of the siblings.

Old post but worth a look for someone who stumbles upon like me

ISNULL(NULLIF(ColumnName, ' '), NULL) IS NOT NULL

ISNULL(NULLIF(ColumnName, ' '), NULL) IS NULL

Try:

insert into account_type_standard (account_type_Standard_id, tax_status_id, recipient_id)
select account_type_standard_seq.nextval,
       ts.tax_status_id, 
       ( select r.recipient_id
         from recipient r
         where r.recipient_code = ?
       )
from tax_status ts
where ts.tax_status_code = ?

Consider:

class Bike(object):
    def __init__(self, name, weight, cost):
        self.name = name
        self.weight = weight
        self.cost = cost

bikes = {
    # Bike designed for children"
    "Trike": Bike("Trike", 20, 100),      # <--
    # Bike designed for everyone"
    "Kruzer": Bike("Kruzer", 50, 165),    # <--
    }

# Markup of 20% on all sales
margin = .2
# Revenue minus cost after sale
for bike in bikes.values():
    profit = bike.cost * margin
    print(profit)

Output:

33.0
20.0

The difference is that in your bikes dictionary, you're initializing the values as lists [...]. Instead, it looks like the rest of your code wants Bike instances. So create Bike instances: Bike(...).

As for your error

AttributeError: 'list' object has no attribute 'cost'

this will occur when you try to call .cost on a list object. Pretty straightforward, but we can figure out what happened by looking at where you call .cost -- in this line:

profit = bike.cost * margin

This indicates that at least one bike (that is, a member of bikes.values() is a list). If you look at where you defined bikes you can see that the values were, in fact, lists. So this error makes sense.

But since your class has a cost attribute, it looked like you were trying to use Bike instances as values, so I made that little change:

[...] -> Bike(...)

and you're all set.

$('li[rel=7]').siblings().andSelf();

// or:

$('li[rel=7]').parent().children();

Now that you added that comment explaining that you want to "form an array of rels per column", you should do this:

var rels = [];

$('ul').each(function() {
    var localRels = [];

    $(this).find('li').each(function(){
        localRels.push( $(this).attr('rel') );
    });

    rels.push(localRels);
});

Use ` backticks for MYSQL reserved words...

table name "table" is reserved word for MYSQL...

so your query should be as follows...

$sql="INSERT INTO `table` (`username`, `password`)
VALUES
('$_POST[username]','$_POST[password]')";

I made this like the following way:

try {
    readImageInformation(new File(contentUri.getPath()));

} catch (IOException e) {
    readImageInformation(new File(getRealPathFromURI(context,
                contentUri)));
}

public static String getRealPathFromURI(Context context, Uri contentUri) {
        String[] proj = { MediaStore.Images.Media.DATA };
        Cursor cursor = context.getContentResolver().query(contentUri, proj,
                null, null, null);
        int column_index = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
}

So basically first I try to use a file i.e. picture taken by camera and saved on SD card. This don't work for image returned by: Intent photoPickerIntent = new Intent(Intent.ACTION_PICK); That case there is a need to convert Uri to real path by getRealPathFromURI() function. So the conclusion is that it depends on what type of Uri you want to convert to File.

What does the “at” (@) symbol do in Python?

In short, it is used in decorator syntax and for matrix multiplication.

In the context of decorators, this syntax:

@decorator
def decorated_function():
    """this function is decorated"""

is equivalent to this:

def decorated_function():
    """this function is decorated"""

decorated_function = decorator(decorated_function)

In the context of matrix multiplication, a @ b invokes a.__matmul__(b) - making this syntax:

a @ b

equivalent to

dot(a, b)

and

a @= b

equivalent to

a = dot(a, b)

where dot is, for example, the numpy matrix multiplication function and a and b are matrices.

How could you discover this on your own?

I also do not know what to search for as searching Python docs or Google does not return relevant results when the @ symbol is included.

If you want to have a rather complete view of what a particular piece of python syntax does, look directly at the grammar file. For the Python 3 branch:

~$ grep -C 1 "@" cpython/Grammar/Grammar 

decorator: '@' dotted_name [ '(' [arglist] ')' ] NEWLINE
decorators: decorator+
--
testlist_star_expr: (test|star_expr) (',' (test|star_expr))* [',']
augassign: ('+=' | '-=' | '*=' | '@=' | '/=' | '%=' | '&=' | '|=' | '^=' |
            '<<=' | '>>=' | '**=' | '//=')
--
arith_expr: term (('+'|'-') term)*
term: factor (('*'|'@'|'/'|'%'|'//') factor)*
factor: ('+'|'-'|'~') factor | power

We can see here that @ is used in three contexts:

• decorators
• an operator between factors
• an augmented assignment operator

Decorator Syntax:

A google search for "decorator python docs" gives as one of the top results, the "Compound Statements" section of the "Python Language Reference." Scrolling down to the section on function definitions, which we can find by searching for the word, "decorator", we see that... there's a lot to read. But the word, "decorator" is a link to the glossary, which tells us:

decorator

A function returning another function, usually applied as a function transformation using the @wrapper syntax. Common examples for decorators are classmethod() and staticmethod().

The decorator syntax is merely syntactic sugar, the following two function definitions are semantically equivalent:

def f(...):
    ...
f = staticmethod(f)

@staticmethod
def f(...):
    ...

The same concept exists for classes, but is less commonly used there. See the documentation for function definitions and class definitions for more about decorators.

So, we see that

@foo
def bar():
    pass

is semantically the same as:

def bar():
    pass

bar = foo(bar)

They are not exactly the same because Python evaluates the foo expression (which could be a dotted lookup and a function call) before bar with the decorator (@) syntax, but evaluates the foo expression after bar in the other case.

_{(If this difference makes a difference in the meaning of your code, you should reconsider what you're doing with your life, because that would be pathological.)}

Stacked Decorators

If we go back to the function definition syntax documentation, we see:

@f1(arg)
@f2
def func(): pass

is roughly equivalent to

def func(): pass
func = f1(arg)(f2(func))

This is a demonstration that we can call a function that's a decorator first, as well as stack decorators. Functions, in Python, are first class objects - which means you can pass a function as an argument to another function, and return functions. Decorators do both of these things.

If we stack decorators, the function, as defined, gets passed first to the decorator immediately above it, then the next, and so on.

That about sums up the usage for @ in the context of decorators.

The Operator, @

In the lexical analysis section of the language reference, we have a section on operators, which includes @, which makes it also an operator:

The following tokens are operators:

+       -       *       **      /       //      %      @
<<      >>      &       |       ^       ~
<       >       <=      >=      ==      !=

and in the next page, the Data Model, we have the section Emulating Numeric Types,

object.__add__(self, other)
object.__sub__(self, other) 
object.__mul__(self, other) 
object.__matmul__(self, other) 
object.__truediv__(self, other) 
object.__floordiv__(self, other)

[...] These methods are called to implement the binary arithmetic operations (+, -, *, @, /, //, [...]

And we see that __matmul__ corresponds to @. If we search the documentation for "matmul" we get a link to What's new in Python 3.5 with "matmul" under a heading "PEP 465 - A dedicated infix operator for matrix multiplication".

it can be implemented by defining __matmul__(), __rmatmul__(), and __imatmul__() for regular, reflected, and in-place matrix multiplication.

(So now we learn that @= is the in-place version). It further explains:

Matrix multiplication is a notably common operation in many fields of mathematics, science, engineering, and the addition of @ allows writing cleaner code:

S = (H @ beta - r).T @ inv(H @ V @ H.T) @ (H @ beta - r)

instead of:

S = dot((dot(H, beta) - r).T,
        dot(inv(dot(dot(H, V), H.T)), dot(H, beta) - r))

While this operator can be overloaded to do almost anything, in numpy, for example, we would use this syntax to calculate the inner and outer product of arrays and matrices:

>>> from numpy import array, matrix
>>> array([[1,2,3]]).T @ array([[1,2,3]])
array([[1, 2, 3],
       [2, 4, 6],
       [3, 6, 9]])
>>> array([[1,2,3]]) @ array([[1,2,3]]).T
array([[14]])
>>> matrix([1,2,3]).T @ matrix([1,2,3])
matrix([[1, 2, 3],
        [2, 4, 6],
        [3, 6, 9]])
>>> matrix([1,2,3]) @ matrix([1,2,3]).T
matrix([[14]])

Inplace matrix multiplication: @=

While researching the prior usage, we learn that there is also the inplace matrix multiplication. If we attempt to use it, we may find it is not yet implemented for numpy:

>>> m = matrix([1,2,3])
>>> m @= m.T
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: In-place matrix multiplication is not (yet) supported. Use 'a = a @ b' instead of 'a @= b'.

When it is implemented, I would expect the result to look like this:

>>> m = matrix([1,2,3])
>>> m @= m.T
>>> m
matrix([[14]])

You have a process that is already using that port. netstat -tulpn will enable one to find the process ID of that is using a particular port.

You can switch to manual build so can control when this is done. Just make sure that Project > Build Automatically from the main menu is unchecked.

I would like to extend Mohamed Elrashid answer, in case you require to pass a variable from the child widget to the parent widget

On child widget:

class ChildWidget extends StatefulWidget {
  final Function() notifyParent;
  ChildWidget({Key key, @required this.notifyParent}) : super(key: key);
}

On parent widget

void refresh(dynamic childValue) {
  setState(() {
    _parentVariable = childValue;
  });
}

On parent widget: pass the function above to the child widget

new ChildWidget( notifyParent: refresh ); 

On child widget: call the parent function with any variable from the the child widget

widget.notifyParent(childVariable);

Quick fix, add this in your options:

curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false)

Now you have no idea what host you're actually connecting to, because cURL will not verify the certificate in any way. Hope you enjoy man-in-the-middle attacks!

Or just add it to your current function:

/**
 * Get a web file (HTML, XHTML, XML, image, etc.) from a URL.  Return an
 * array containing the HTTP server response header fields and content.
 */
function get_web_page( $url )
{
    $options = array(
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => false,    // don't return headers
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_USERAGENT      => "spider", // who am i
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
        CURLOPT_TIMEOUT        => 120,      // timeout on response
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
        CURLOPT_SSL_VERIFYPEER => false     // Disabled SSL Cert checks
    );

    $ch      = curl_init( $url );
    curl_setopt_array( $ch, $options );
    $content = curl_exec( $ch );
    $err     = curl_errno( $ch );
    $errmsg  = curl_error( $ch );
    $header  = curl_getinfo( $ch );
    curl_close( $ch );

    $header['errno']   = $err;
    $header['errmsg']  = $errmsg;
    $header['content'] = $content;
    return $header;
}

I had a similar problem and for encrypt/decrypt i came up with this solution:

public static byte[] generateKey(String password) throws Exception
{
    byte[] keyStart = password.getBytes("UTF-8");

    KeyGenerator kgen = KeyGenerator.getInstance("AES");
    SecureRandom sr = SecureRandom.getInstance("SHA1PRNG", "Crypto");
    sr.setSeed(keyStart);
    kgen.init(128, sr);
    SecretKey skey = kgen.generateKey();
    return skey.getEncoded();
}

public static byte[] encodeFile(byte[] key, byte[] fileData) throws Exception
{

    SecretKeySpec skeySpec = new SecretKeySpec(key, "AES");
    Cipher cipher = Cipher.getInstance("AES");
    cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
    byte[] encrypted = cipher.doFinal(fileData);

    return encrypted;
}

public static byte[] decodeFile(byte[] key, byte[] fileData) throws Exception
{
    SecretKeySpec skeySpec = new SecretKeySpec(key, "AES");
    Cipher cipher = Cipher.getInstance("AES");
    cipher.init(Cipher.DECRYPT_MODE, skeySpec);

    byte[] decrypted = cipher.doFinal(fileData);

    return decrypted;
}

To save a encrypted file to sd do:

File file = new File(Environment.getExternalStorageDirectory() + File.separator + "your_folder_on_sd", "file_name");
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file));
byte[] yourKey = generateKey("password");
byte[] filesBytes = encodeFile(yourKey, yourByteArrayContainigDataToEncrypt);
bos.write(fileBytes);
bos.flush();
bos.close();

To decode a file use:

byte[] yourKey = generateKey("password");
byte[] decodedData = decodeFile(yourKey, bytesOfYourFile);

For reading in a file to a byte Array there a different way out there. A Example: http://examples.javacodegeeks.com/core-java/io/fileinputstream/read-file-in-byte-array-with-fileinputstream/

Separate your rules with a semi colon in a single declaration:

<span style="color:blue;font-style:italic">Test</span>

I use a solution that is similar to that of David above, but with an additional twist if some rows should be excluded from the count. This assumes that [UserAccountKey] is never null.

-- subtract an extra 1 if null was ranked within the partition,
-- which only happens if there were rows where [Include] <> 'Y'
dense_rank() over (
  partition by [Mth] 
  order by case when [Include] = 'Y' then [UserAccountKey] else null end asc
) 
+ dense_rank() over (
  partition by [Mth] 
  order by case when [Include] = 'Y' then [UserAccountKey] else null end desc
)
- max(case when [Include] = 'Y' then 0 else 1 end) over (partition by [Mth])
- 1

An SQL Fiddle with an extended example can be found here.

Use Reflection:

Type type = obj.GetType();
PropertyInfo[] properties = type.GetProperties();

foreach (PropertyInfo property in properties)
{
    Console.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(obj, null));
}

for Excel - what tools/reference item must be added to gain access to BindingFlags, as there is no "System.Reflection" entry in the list

Edit: You can also specify a BindingFlags value to type.GetProperties():

BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;
PropertyInfo[] properties = type.GetProperties(flags);

That will restrict the returned properties to public instance properties (excluding static properties, protected properties, etc).

You don't need to specify BindingFlags.GetProperty, you use that when calling type.InvokeMember() to get the value of a property.

If this is the current url use window.location.pathname otherwise use this regular expression:

var reg = /.+?\:\/\/.+?(\/.+?)(?:#|\?|$)/;
var pathname = reg.exec( 'http://www.somedomain.com/account/search?filter=a#top' )[1];

select a.ip, a.os, a.hostname, a.port, a.protocol,
       b.state
from a
left join b on a.ip = b.ip 
           and a.port = b.port

The highest voted answers here are perfectly fine I just want to add up the use of await so that the functionality asked for can be archived:

const documentCount = await userModel.count({});
console.log( "Number of users:", documentCount );

It's recommended to use countDocuments() over 'count()' as it will be deprecated going on. So, for now, the perfect code would be:

const documentCount = await userModel.countDocuments({});
console.log( "Number of users:", documentCount );

As others have said, there is now an option for Ctrl+Shf+Vfor paste in Windows 10 Insider build #17643.

Unfortunately this isn't in my muscle memory and as a user of TTY terminals I'd like to use Shf+Ins as I do on all the Linux boxes I connect to.

This is possible on Windows 10 if you install ConEmu which wraps the terminal in a new GUI and allows Shf+Ins for paste. It also allows you to tweak the behaviour in the Properties.

The Console looks like this:

Copy options:

Paste options:

Shf+Ins works out of the box. I can't remember if you need to configure bash as one of the shells it uses but if you do, here is the task properties to add it:

Also allows tabbed Consoles (including different types, cmd.exe, powershell etc). I've been using this since early Windows 7 and in those days it made the command line on Windows usable!

Create MongoDB Service in Windows. First Open cmd with administrator

mongod --port 27017 --dbpath "a mongodb storage actual path e.g: d:\mongo_storage\data" --logpath="a log path e.g: d:\mongo_storage\log\log.txt" --install --serviceName "MongoDB"

After that

Start Service

net start MongoDB

I think it's a better practice to serialize your REST call parameters, usually by JSON-encoding them:

/appointments?users=[id1,id2]

or even:

/appointments?params={users:[id1,id2]}

Then you un-encode them on the server. This is going to give you more flexibility in the long run.

Just make sure to URLEncode the params as well before you send them!

You may also want to use this to detect HTML 5 audio in some cases:

1. Go to Eclipse Folder
2. Find Eclipse Icon in Eclipse Folder
3. Right Click on it you will get option "Show Package Content"
4. Contents folder will open on screen
5. If you are on Mac then you'll find "MacOS"
6. Open MacOS folder you'll find eclipse.ini file

7. Open it in word or any file editor for edit

   ...

   -XX:MaxPermSize=256m
   
   -Xms40m
   
   -Xmx512m
   

   ...

8. Replace -Xmx512m to -Xmx1024m

9. Save the file and restart your Eclipse
10. Have a Nice time :)

I successfully use the following method in one file,

But come up with exactly the same error again... Only the last line come up with error

Newpath = Mid(ThisWorkbook.FullName, 1, _
 Len(ThisWorkbook.FullName) - Len(ThisWorkbook.Name)) & "\" & "ABC - " & Format(Date, "dd-mm-yyyy") & ".xlsm"
ThisWorkbook.SaveAs (Newpath)

This goes to you model:

public function count_news_by_category($cat)
{
    return $this->db
        ->where('category', $cat)
        ->where('is_enabled', 1)
        ->count_all_results('news');
}

It'a an example from my current project.

According to benchmarking this query works faster than if you do the following:

$this->db->select('*')->from('news')->where(...); 
$q = $this->db->get(); 
return $q->num_rows();

For Autodidacts:

function BaseClass(toBePrivate){
    var morePrivates;
    this.isNotPrivate = 'I know';
    // add your stuff
}
var o = BaseClass.prototype;
// add your prototype stuff
o.stuff_is_never_private = 'whatever_except_getter_and_setter';


// MiddleClass extends BaseClass
function MiddleClass(toBePrivate){
    BaseClass.call(this);
    // add your stuff
    var morePrivates;
    this.isNotPrivate = 'I know';
}
var o = MiddleClass.prototype = Object.create(BaseClass.prototype);
MiddleClass.prototype.constructor = MiddleClass;
// add your prototype stuff
o.stuff_is_never_private = 'whatever_except_getter_and_setter';



// TopClass extends MiddleClass
function TopClass(toBePrivate){
    MiddleClass.call(this);
    // add your stuff
    var morePrivates;
    this.isNotPrivate = 'I know';
}
var o = TopClass.prototype = Object.create(MiddleClass.prototype);
TopClass.prototype.constructor = TopClass;
// add your prototype stuff
o.stuff_is_never_private = 'whatever_except_getter_and_setter';


// to be continued...

Create "instance" with getter and setter:

function doNotExtendMe(toBePrivate){
    var morePrivates;
    return {
        // add getters, setters and any stuff you want
    }
}

Using composer you can specify the version you want easily by running

composer create-project laravel/laravel="5.1.*" myProject

Using the 5.1.* will ensure that you get all the latest patches in the 5.1 branch.

It is possible, they are not connected in InterfaceBuilder.

Text colour(colorWithRed:(188/255) green:(149/255) blue:(88/255)) is correct, may be mistake in connections,

backgroundcolor is used for the background colour of label and textcolor is used for property textcolor.

There is often the tip to use 'echo.'

But that is slow, and it could fail with an error message, as cmd.exe will search first for a file named 'echo' (without extension) and only when the file doesn't exists it outputs an empty line.

You could use echo(. This is approximately 20 times faster, and it works always. The only drawback could be that it looks odd.

More about the different ECHO:/\ variants is at DOS tips: ECHO. FAILS to give text or blank line.

Best way would be first of all find all files in directory then use AWK NR (Number of Records Variable)

below is the command :

find <directory path>  -type f | awk  'END{print NR}'

example : - find /tmp/ -type f | awk 'END{print NR}'

Here is settings.xml --> C:\maven\conf\settings.xml

Try this. It works with me. Hope you too!

List<YOUR_OBJECT> testList = new ArrayList<>();_x000D_
testList.add(test1);_x000D_
_x000D_
Gson gson = new Gson();_x000D_
_x000D_
String json = gson.toJson(testList);_x000D_
_x000D_
Type type = new TypeToken<ArrayList<YOUR_OBJECT>>(){}.getType();_x000D_
_x000D_
ArrayList<YOUR_OBJECT> array = gson.fromJson(json, type);

Something along the lines of

StringWriter errors = new StringWriter();
ex.printStackTrace(new PrintWriter(errors));
return errors.toString();

Ought to be what you need.

Relevant documentation:

• StringWriter
• PrintWriter
• Throwable

I encountered with the same problem when i am working on autobahn related project.

1) So I download the setuptools.-0.9.8.tar.gz form https://pypi.python.org/packages/source/s/setuptools/ and extract it.

2 )Then i get the pkg_resources module and copy it to the folder where it needed. **in my case that folder was C:\Python27\Lib\site-packages\autobahn

I can't add anything but a code example to the other two answers: however, I find it can be useful to see it in action (the other answers, in my opinion, are better because they explain it).

DECLARE @testLeft TABLE (ID INT, SomeValue VARCHAR(1))
DECLARE @testRight TABLE (ID INT, SomeOtherValue VARCHAR(1))

INSERT INTO @testLeft (ID, SomeValue) VALUES (1, 'A')
INSERT INTO @testLeft (ID, SomeValue) VALUES (2, 'B')
INSERT INTO @testLeft (ID, SomeValue) VALUES (3, 'C')


INSERT INTO @testRight (ID, SomeOtherValue) VALUES (1, 'X')
INSERT INTO @testRight (ID, SomeOtherValue) VALUES (3, 'Z')

SELECT l.*
FROM 
    @testLeft l
     LEFT JOIN 
    @testRight r ON 
        l.ID = r.ID
WHERE r.ID IS NULL 

Another native solution (in coffee):

el = document.getElementsByTagName 'b'

docFrag = document.createDocumentFragment()
docFrag.appendChild el.firstChild while el.childNodes.length

el.parentNode.replaceChild docFrag, el

I don't know if it's faster than user113716's solution, but it might be easier to understand for some.

Data-Binding

You go around making your webpage, and keep on putting {{data bindings}} whenever you feel you would have dynamic data. Angular will then provide you a $scope handler, which you can populate (statically or through calls to the web server).

This is a good understanding of data-binding. I think you've got that down.

DOM Manipulation

For simple DOM manipulation, which doesnot involve data manipulation (eg: color changes on mousehover, hiding/showing elements on click), jQuery or old-school js is sufficient and cleaner. This assumes that the model in angular's mvc is anything that reflects data on the page, and hence, css properties like color, display/hide, etc changes dont affect the model.

I can see your point here about "simple" DOM manipulation being cleaner, but only rarely and it would have to be really "simple". I think DOM manipulation is one the areas, just like data-binding, where Angular really shines. Understanding this will also help you see how Angular considers its views.

I'll start by comparing the Angular way with a vanilla js approach to DOM manipulation. Traditionally, we think of HTML as not "doing" anything and write it as such. So, inline js, like "onclick", etc are bad practice because they put the "doing" in the context of HTML, which doesn't "do". Angular flips that concept on its head. As you're writing your view, you think of HTML as being able to "do" lots of things. This capability is abstracted away in angular directives, but if they already exist or you have written them, you don't have to consider "how" it is done, you just use the power made available to you in this "augmented" HTML that angular allows you to use. This also means that ALL of your view logic is truly contained in the view, not in your javascript files. Again, the reasoning is that the directives written in your javascript files could be considered to be increasing the capability of HTML, so you let the DOM worry about manipulating itself (so to speak). I'll demonstrate with a simple example.

This is the markup we want to use. I gave it an intuitive name.

<div rotate-on-click="45"></div>

First, I'd just like to comment that if we've given our HTML this functionality via a custom Angular Directive, we're already done. That's a breath of fresh air. More on that in a moment.

Implementation with jQuery

live demo here (click).

function rotate(deg, elem) {
  $(elem).css({
    webkitTransform: 'rotate('+deg+'deg)', 
    mozTransform: 'rotate('+deg+'deg)', 
    msTransform: 'rotate('+deg+'deg)', 
    oTransform: 'rotate('+deg+'deg)', 
    transform: 'rotate('+deg+'deg)'    
  });
}

function addRotateOnClick($elems) {
  $elems.each(function(i, elem) {
    var deg = 0;
    $(elem).click(function() {
      deg+= parseInt($(this).attr('rotate-on-click'), 10);
      rotate(deg, this);
    });
  });
}

addRotateOnClick($('[rotate-on-click]'));

Implementation with Angular

live demo here (click).

app.directive('rotateOnClick', function() {
  return {
    restrict: 'A',
    link: function(scope, element, attrs) {
      var deg = 0;
      element.bind('click', function() {
        deg+= parseInt(attrs.rotateOnClick, 10);
        element.css({
          webkitTransform: 'rotate('+deg+'deg)', 
          mozTransform: 'rotate('+deg+'deg)', 
          msTransform: 'rotate('+deg+'deg)', 
          oTransform: 'rotate('+deg+'deg)', 
          transform: 'rotate('+deg+'deg)'    
        });
      });
    }
  };
});

Pretty light, VERY clean and that's just a simple manipulation! In my opinion, the angular approach wins in all regards, especially how the functionality is abstracted away and the dom manipulation is declared in the DOM. The functionality is hooked onto the element via an html attribute, so there is no need to query the DOM via a selector, and we've got two nice closures - one closure for the directive factory where variables are shared across all usages of the directive, and one closure for each usage of the directive in the link function (or compile function).

Two-way data binding and directives for DOM manipulation are only the start of what makes Angular awesome. Angular promotes all code being modular, reusable, and easily testable and also includes a single-page app routing system. It is important to note that jQuery is a library of commonly needed convenience/cross-browser methods, but Angular is a full featured framework for creating single page apps. The angular script actually includes its own "lite" version of jQuery so that some of the most essential methods are available. Therefore, you could argue that using Angular IS using jQuery (lightly), but Angular provides much more "magic" to help you in the process of creating apps.

This is a great post for more related information: How do I “think in AngularJS” if I have a jQuery background?

General differences.

The above points are aimed at the OP's specific concerns. I'll also give an overview of the other important differences. I suggest doing additional reading about each topic as well.

Angular and jQuery can't reasonably be compared.

Angular is a framework, jQuery is a library. Frameworks have their place and libraries have their place. However, there is no question that a good framework has more power in writing an application than a library. That's exactly the point of a framework. You're welcome to write your code in plain JS, or you can add in a library of common functions, or you can add a framework to drastically reduce the code you need to accomplish most things. Therefore, a more appropriate question is:

Why use a framework?

Good frameworks can help architect your code so that it is modular (therefore reusable), DRY, readable, performant and secure. jQuery is not a framework, so it doesn't help in these regards. We've all seen the typical walls of jQuery spaghetti code. This isn't jQuery's fault - it's the fault of developers that don't know how to architect code. However, if the devs did know how to architect code, they would end up writing some kind of minimal "framework" to provide the foundation (achitecture, etc) I discussed a moment ago, or they would add something in. For example, you might add RequireJS to act as part of your framework for writing good code.

Here are some things that modern frameworks are providing:

• Templating
• Data-binding
• routing (single page app)
• clean, modular, reusable architecture
• security
• additional functions/features for convenience

Before I further discuss Angular, I'd like to point out that Angular isn't the only one of its kind. Durandal, for example, is a framework built on top of jQuery, Knockout, and RequireJS. Again, jQuery cannot, by itself, provide what Knockout, RequireJS, and the whole framework built on top them can. It's just not comparable.

If you need to destroy a planet and you have a Death Star, use the Death star.

Angular (revisited).

Building on my previous points about what frameworks provide, I'd like to commend the way that Angular provides them and try to clarify why this is matter of factually superior to jQuery alone.

DOM reference.

In my above example, it is just absolutely unavoidable that jQuery has to hook onto the DOM in order to provide functionality. That means that the view (html) is concerned about functionality (because it is labeled with some kind of identifier - like "image slider") and JavaScript is concerned about providing that functionality. Angular eliminates that concept via abstraction. Properly written code with Angular means that the view is able to declare its own behavior. If I want to display a clock:

<clock></clock>

Done.

Yes, we need to go to JavaScript to make that mean something, but we're doing this in the opposite way of the jQuery approach. Our Angular directive (which is in it's own little world) has "augumented" the html and the html hooks the functionality into itself.

MVW Architecure / Modules / Dependency Injection

Angular gives you a straightforward way to structure your code. View things belong in the view (html), augmented view functionality belongs in directives, other logic (like ajax calls) and functions belong in services, and the connection of services and logic to the view belongs in controllers. There are some other angular components as well that help deal with configuration and modification of services, etc. Any functionality you create is automatically available anywhere you need it via the Injector subsystem which takes care of Dependency Injection throughout the application. When writing an application (module), I break it up into other reusable modules, each with their own reusable components, and then include them in the bigger project. Once you solve a problem with Angular, you've automatically solved it in a way that is useful and structured for reuse in the future and easily included in the next project. A HUGE bonus to all of this is that your code will be much easier to test.

It isn't easy to make things "work" in Angular.

THANK GOODNESS. The aforementioned jQuery spaghetti code resulted from a dev that made something "work" and then moved on. You can write bad Angular code, but it's much more difficult to do so, because Angular will fight you about it. This means that you have to take advantage (at least somewhat) to the clean architecture it provides. In other words, it's harder to write bad code with Angular, but more convenient to write clean code.

Angular is far from perfect. The web development world is always growing and changing and there are new and better ways being put forth to solve problems. Facebook's React and Flux, for example, have some great advantages over Angular, but come with their own drawbacks. Nothing's perfect, but Angular has been and is still awesome for now. Just as jQuery once helped the web world move forward, so has Angular, and so will many to come.

If you have downloaded the latest Version 4.3.4 then just follow these steps.

• Download the package, unzip and place in your web directory or root folder.
• Provide the read write permissions to that folder (preferably Ubuntu machines )
• Create view page test.php
• Paste the below mentioned code it should work fine.

Load the mentioned js file

<script type="text/javascript" src="/ckeditor/ckeditor.js"></script>
<textarea class="ckeditor" name="editor"></textarea>

Simplistically:

• ~ specifies ancestors
• ^ specifies parents

You can specify one or more branches when merging. Then a commit has two or more parents and then ^ is useful to indicate parents.

Suppose you are on branch A and you have two more branches: B and C.

On each branch the three last commits are:

• A: A1, A2, A3
• B: B1, B2, B3
• C: C1, C3, C3

If now on branch A you execute the command:

git merge B C

then you are combining three branches together (here your merge commit has three parents)

and

~ indicates the n'th ancestor in the first branch, so

• HEAD~ indicates A3
• HEAD~2 indicates A2
• HEAD~3 indicates A1

^ indicates the n'th parent, so

• HEAD^ indicates A3
• HEAD^2 indicates B3
• HEAD^3 indicates C3

The next use of ~ or ^ next to each other is in the context of the commit designated by previous characters.

Notice 1:

• HEAD~3 is always equal to: HEAD~~~ and to: HEAD^^^ (every indicates A1),

        and generally:

• HEAD~n is always equal to: HEAD~...~ (n times ~) and to: HEAD^...^ (n times ^).

Notice 2:

• HEAD^3 is not the same as HEAD^^^ (the first indicates C3 and the second indicates A1),

        and generally:

• HEAD^1 is the same as HEAD^,
• but for n > 1: HEAD^n is always not the same as HEAD^...^ (n times ~).

One of the first differences that I can recall from top of my head are multiple domains running in the same server, partial resource retrieval, this allows you to retrieve and speed up the download of a resource (it's what almost every download accelerator does).

If you want to develop an application like a website or similar, you don't need to worry too much about the differences but you should know the difference between GET and POST verbs at least.

Now if you want to develop a browser then yes, you will have to know the complete protocol as well as if you are trying to develop a HTTP server.

If you are only interested in knowing the HTTP protocol I would recommend you starting with HTTP/1.1 instead of 1.0.

Here is a solution I made using the above ideas that can be used for TextBoxFor and PasswordFor:

public static class HtmlHelperEx
{
    public static MvcHtmlString TextBoxWithPlaceholderFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper,
        Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        return htmlHelper.TextBoxFor(expression, htmlAttributes.AddAttribute("placeholder", metadata.Watermark));

    }

    public static MvcHtmlString PasswordWithPlaceholderFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper,
        Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        return htmlHelper.PasswordFor(expression, htmlAttributes.AddAttribute("placeholder", metadata.Watermark));

    }
}

public static class HtmlAttributesHelper
{
    public static IDictionary<string, object> AddAttribute(this object htmlAttributes, string name, object value)
    {
        var dictionary = htmlAttributes == null ? new Dictionary<string, object>() : htmlAttributes.ToDictionary();
        if (!String.IsNullOrWhiteSpace(name) && value != null && !String.IsNullOrWhiteSpace(value.ToString()))
            dictionary.Add(name, value);
        return dictionary;
    }

    public static IDictionary<string, object> ToDictionary(this object obj)
    {
        return TypeDescriptor.GetProperties(obj)
            .Cast<PropertyDescriptor>()
            .ToDictionary(property => property.Name, property => property.GetValue(obj));
    }
}

2018 Update

Now you can use just window.scrollTo({ top: 0, behavior: 'smooth' }) to get the page scrolled with a smooth effect.

const btn = document.getElementById('elem');_x000D_
_x000D_
btn.addEventListener('click', () => window.scrollTo({_x000D_
  top: 400,_x000D_
  behavior: 'smooth',_x000D_
}));

#x {_x000D_
  height: 1000px;_x000D_
  background: lightblue;_x000D_
}

<div id='x'>_x000D_
  <button id='elem'>Click to scroll</button>_x000D_
</div>

Older solutions

You can do something like this:

var btn = document.getElementById('x');_x000D_
_x000D_
btn.addEventListener("click", function() {_x000D_
  var i = 10;_x000D_
  var int = setInterval(function() {_x000D_
    window.scrollTo(0, i);_x000D_
    i += 10;_x000D_
    if (i >= 200) clearInterval(int);_x000D_
  }, 20);_x000D_
})

body {_x000D_
  background: #3a2613;_x000D_
  height: 600px;_x000D_
}

<button id='x'>click</button>

ES6 recursive approach:

const btn = document.getElementById('elem');_x000D_
_x000D_
const smoothScroll = (h) => {_x000D_
  let i = h || 0;_x000D_
  if (i < 200) {_x000D_
    setTimeout(() => {_x000D_
      window.scrollTo(0, i);_x000D_
      smoothScroll(i + 10);_x000D_
    }, 10);_x000D_
  }_x000D_
}_x000D_
_x000D_
btn.addEventListener('click', () => smoothScroll());

body {_x000D_
  background: #9a6432;_x000D_
  height: 600px;_x000D_
}

<button id='elem'>click</button>

ctrl + shift + right-click it works better that way

There is also the C way of doing callbacks: function pointers

//Define a type for the callback signature,
//it is not necessary, but makes life easier

//Function pointer called CallbackType that takes a float
//and returns an int
typedef int (*CallbackType)(float);  


void DoWork(CallbackType callback)
{
  float variable = 0.0f;

  //Do calculations

  //Call the callback with the variable, and retrieve the
  //result
  int result = callback(variable);

  //Do something with the result
}

int SomeCallback(float variable)
{
  int result;

  //Interpret variable

  return result;
}

int main(int argc, char ** argv)
{
  //Pass in SomeCallback to the DoWork
  DoWork(&SomeCallback);
}

Now if you want to pass in class methods as callbacks, the declarations to those function pointers have more complex declarations, example:

//Declaration:
typedef int (ClassName::*CallbackType)(float);

//This method performs work using an object instance
void DoWorkObject(CallbackType callback)
{
  //Class instance to invoke it through
  ClassName objectInstance;

  //Invocation
  int result = (objectInstance.*callback)(1.0f);
}

//This method performs work using an object pointer
void DoWorkPointer(CallbackType callback)
{
  //Class pointer to invoke it through
  ClassName * pointerInstance;

  //Invocation
  int result = (pointerInstance->*callback)(1.0f);
}

int main(int argc, char ** argv)
{
  //Pass in SomeCallback to the DoWork
  DoWorkObject(&ClassName::Method);
  DoWorkPointer(&ClassName::Method);
}

Considering a part of a Comment made by @SSilk my end goal has really been to get everything to the right of that last occurence an alternative approach with a very simple formula is to copy a column (say A) of strings and on the copy (say ColumnB) apply Find and Replace. For instance taking the example: Drive:\Folder\SubFolder\Filename.ext

This returns what remains (here Filename.ext) after the last instance of whatever character is chosen (here \) which is sometimes the objective anyway and facilitates finding the position of the last such character with a short formula such as:

=FIND(B1,A1)-1

Use safely-turning-a-json-string-into-an-object

var jsonString = '{"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}';

var jsonObject = (new Function("return " + jsonString))();

alert(jsonObject.id);

Although <input> ignores the rows attribute, you can take advantage of the fact that <textarea> doesn't have to be inside <form> tags, but can still be a part of a form by referencing the form's id:

<form method="get" id="testformid">
    <input type="submit" />
</form> 
<textarea form ="testformid" name="taname" id="taid" cols="35" wrap="soft"></textarea>

Of course, <textarea> now appears below "submit" button, but maybe you'll find a way to reposition it.

add {3,5} to your expression which means length between 3 to 5

/^([a-zA-Z0-9_-]){3,5}$/

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

You can try this:

Calendar sDate = Calendar.getInstance();
Calendar eDate = Calendar.getInstance();
sDate.setTime(startDate.getTime());
eDate.setTime(endDate.getTime());
int difInMonths = sDate.get(Calendar.MONTH) - eDate.get(Calendar.MONTH);

I think this should work. I used something similar for my project and it worked for what I needed (year diff). You get a Calendar from a Date and just get the month's diff.

The best and shortest way to use the table System.exit.

System.exit(0);

The VM stops further execution and program will exit.

After reading several answers, I decided to do it with a simple solution: Instead of a shortcut, I made a .bat with only one line to call the main .bat and it works like I wanted.

As I needed to check if there are items from a list in a (long) string, I ended up with this one:

listOfStrings.Any(x => myString.ToUpper().Contains(x.ToUpper()));

Or in vb.net:

listOfStrings.Any(Function(x) myString.ToUpper().Contains(x.ToUpper()))

This question directly asks about joining two lists. However it's pretty high in search even when you are looking for a way of joining many lists (including the case when you joining zero lists).

I think the best option is to use list comprehensions:

>>> a = [[1,2,3], [4,5,6], [7,8,9]]
>>> [x for xs in a for x in xs]
[1, 2, 3, 4, 5, 6, 7, 8, 9]

You can create generators as well:

>>> map(str, (x for xs in a for x in xs))
['1', '2', '3', '4', '5', '6', '7', '8', '9']

Old Answer

Consider this more generic approach:

a = [[1,2,3], [4,5,6], [7,8,9]]
reduce(lambda c, x: c + x, a, [])

Will output:

[1, 2, 3, 4, 5, 6, 7, 8, 9]

Note, this also works correctly when a is [] or [[1,2,3]].

However, this can be done more efficiently with itertools:

a = [[1,2,3], [4,5,6], [7,8,9]]
list(itertools.chain(*a))

If you don't need a list, but just an iterable, omit list().

Update

Alternative suggested by Patrick Collins in the comments could also work for you:

sum(a, [])

function instantiateEmptyObject(obj: object): object {
    if (obj == null) { return {}; }

    const prototype = Object.getPrototypeOf(obj);
    if (!prototype) {
        return {};
    }

    return Object.create(prototype);
}

function quickCopy(src: object, dest: object): object {
    if (dest == null) { return dest; }

    return { ...src, ...dest };
}

quickCopy(src, instantiateEmptyObject(new Customer()));

Edit: Not quite. See comments below.

Java doesn't directly run on anything. It needs to be converted to bytecode by a JVM.

Because JVMs exist for all major platforms, this makes Java platform-independent THROUGH the JVM.

For anyone who don't want to disabled Preview Mode.

As I read whole of comments and I found what I preferred that is the shortcut key to pin the opened file from Quick Open/Ctrl+P or that's mean to keep the opened file to the editor, and yes also don't need to switch your hand to the mouse to double-click on files list.

Thanks to @jontem and @MattLBeck.

Call save command with Ctrl+S (?+s on Mac) is the easiest way to reach what I preferred.

And if you found out you do this to keep opened file to editor quite frequently, yes I preferred you should setting the option "workbench.editor.enablePreview": false or "workbench.editor.enablePreviewFromQuickOpen": false as others mentioned before.

You can use the available() method to ask the stream whether there is any data available at the moment you call it. However, that function isn't guaranteed to work on all types of input streams. That means that you can't use available() to determine whether a call to read() will actually block or not.

Use AppContext. Make sure you create a bean in your context file.

private final static Foo foo = AppContext.getApplicationContext().getBean(Foo.class);

public static void randomMethod() {
     foo.doStuff();
}

You can try running a simple web server based on Twisted

As best place and practice for external API calls is React Lifecycle method componentDidMount(), where after the execution of the API call you should update the local state to be triggered new render() method call, then the changes in the updated local state will be applied on the component view.

As other option for initial external data source call in React is pointed the constructor() method of the class. The constructor is the first method executed on initialization of the component object instance. You could see this approach in the documentation examples for Higher-Order Components.

The method componentWillMount() and UNSAFE_componentWillMount() should not be used for external API calls, because they are intended to be deprecated. Here you could see common reasons, why this method will be deprecated.

Anyway you must never use render() method or method directly called from render() as a point for external API call. If you do this your application will be blocked.

do you use Bash? Go to the file .bashrc in your home directory and set the variable, then export it.

DISPLAY=localhost:0.0 ; export DISPLAY

you can use /etc/bashrc if you want to do it for all the users.

You may also want to look in ~/.bash_profile and /etc/profile

EDIT:

function get_xserver ()

Sometimes there is problem with java configuration. We need to provide it specifically.

<properties>
        <java.version>1.8</java.version>
</properties>

It solved my problem.

I think I got what I was looking for..

data.train <- read.table("Assign2.WineComplete.csv",sep=",",header=T)
fit <- rpart(quality ~ ., method="class",data=data.train)
plot(fit)
text(fit, use.n=TRUE)
summary(fit)

ul {
    width: 100%;
    background: red;
    height: 20px;
    display: flex;
    justify-content: center;
    align-items: center;
}

li {
    background: blue;
    color: white;
    margin-right: 10px;
}

<button type ="button" onclick="location.href='@Url.Action("viewname","Controllername")'"> Button name</button>

for e.g ,

<button type="button" onclick="location.href='@Url.Action("register","Home")'">Register</button>

I believe your solution will only look in the root of each directory path contained in the @INC array. You need something recursive, like:

 perl -e 'foreach (@INC) {
    print `find $_ -type f -name "*.pm"`;
 }'

I would suggest using inline CSS styling.

<table border="1" style="padding-right: 10px;">
<tr>
<td>Content</td>
</tr>
</table>

or

<table border="1">
<tr style="padding-right: 10px;">
<td>Content</td>
</tr>
</table>

or

<table border="1">
<tr>
<td style="padding-right: 10px;">Content</td>
</tr>
</table>

I don't quite follow what you need, but this is what I would do, assuming I understand you needs.

For converting date to string check this thread

Convert java.util.Date to String

And for converting string to date try this,

import java.text.ParseException;
import java.text.SimpleDateFormat;

public class StringToDate
{
    public static void main(String[] args) throws ParseException
    {
        SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");
        String strDate = "14/03/2003 08:05:10";     
        System.out.println("Date - " + sdf.parse(strDate));
    }
}

You could also try using something like StringEscapeUtils to make your life even easier: http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/StringEscapeUtils.html

s = StringEscapeUtils.escapeJava(s);

In order to be able to expose some configuration parameters for your bundle you should consult the documentation for doing so. It's fairly easy to do :)

As of Swift 5, the following code collection works.

 // main dict to start with
 var myDict : Dictionary = [ 1 : "abc", 2 : "cde"]

 // dict(s) to be added to main dict
 let myDictToMergeWith : Dictionary = [ 5 : "l m n"]
 let myDictUpdated : Dictionary = [ 5 : "lmn"]
 let myDictToBeMapped : Dictionary = [ 6 : "opq"]

 myDict[3]="fgh"
 myDict.updateValue("ijk", forKey: 4)

 myDict.merge(myDictToMergeWith){(current, _) in current}
 print(myDict)

 myDict.merge(myDictUpdated){(_, new) in new}
 print(myDict)

 myDictToBeMapped.map {
     myDict[$0.0] = $0.1
 }
 print(myDict)

With a BorderLayout you need to use setPreferredSize instead of setSize

We can also convert data.frame columns generically to a simple vector. as.vector is not enough as it retains the data.frame class and structure, so we also have to pull out the first (and only) element:

df_column_object <- aframe[,2]
simple_column <- df_column_object[[1]]

All the solutions suggested so far require hardcoding column titles. This makes them non-generic (imagine applying this to function arguments).

Alternatively, you could, of course read the column names from the column first and then insert them in the code in the other solutions.

You need to isntall pdo_pgsql package

I had empty settings.xml file in Users/.../.m2/settings.xml. When i added

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      https://maven.apache.org/xsd/settings-1.0.0.xsd">

</settings>

all dependicies were loaded

Just Change the query like this:

SELECT TOP 1 * FROM [HumanResources].[Employee]

where Employee is your table name and HumanResources is your Schema name if I am not wrong.

Hope your problem will be resolved. :)

Raldi's solution can be tightened up to this (the '=>' from the original is not necessary):

my %hash = map { $_,1 } @array;

This technique can also be used for turning text lists into hashes:

my %hash = map { $_,1 } split(",",$line)

Additionally if you have a line of values like this: "foo=1,bar=2,baz=3" you can do this:

my %hash = map { split("=",$_) } split(",",$line);

[EDIT to include]

Another solution offered (which takes two lines) is:

my %hash;
#The values in %hash can only be accessed by doing exists($hash{$key})
#The assignment only works with '= undef;' and will not work properly with '= 1;'
#if you do '= 1;' only the hash key of $array[0] will be set to 1;
@hash{@array} = undef;

Solution

To see the option for USB debugging mode in Nexus 4 or Android 4.2 or higher OS, do the following:

• Open up your device’s “Settings”. This can be done by pressing the Menu button while on your home screen and tapping “System settings”
• Now scroll to the bottom and tap “About phone” or “About tablet”.
• At the “About” screen, scroll to the bottom and tap on “Build number” seven times.
  • Make sure you tap seven times. If you see a “Not need, you are already a developer!” message pop up, then you know you have done it correctly.

Done! By tapping on “Build number” seven times, you have unlocked USB debugging mode on Android 4.2 and higher. You can now enable/disable it whenever you desire by going to “Settings” -> “Developer Options” -> “Debugging” ->” USB debugging”.

CONCLUSION

That was easy. The best part is you only have to do the tap-build-number-seven-times once. After you do it once, USB debugging has been unlocked and you can enable or disable at your leisure. Please restart after done these steps.

Why switch between PHP versions when you can use multiple PHP version at a same time with a single xampp installation? With a single xampp installation, you have 2 options:

1. Run an older PHP version for only the directory of your old project: This will serve the purpose most of the time, you may have one or two old projects that you intend to run with older PHP version. Just configure xampp to run older PHP version only for those project directories.

2. Run an older PHP version on a separate port of xampp: Sometimes you may be upgrading and old project to latest PHP version when you need to run the same project on new and older PHP version back and forth. Then you can set an older PHP version on a different port (say 8056) so when you go to http://localhost/any_project/ xampp runs PHP 7 and when you go to http://localhost:8056/any_project/ xampp runs PHP 5.6.

3. Run an older PHP version on a virtualhost: You can create a virtualhost like localhost56 to run PHP 5.6 while you can use PHP 7 on localhost.

Lets set it up.

Step 1: Download PHP

So you have PHP 7 running under xampp, you want to add an older PHP version to it, say PHP 5.6. Download the nts (Non Thread Safe) version of PHP zip archive from php.net (see archive for older versions) and extract the files under c:\xampp\php56. The thread safe version does not include php-cgi.exe.

Step 2: Configure php.ini

Open c:\xampp\php56\php.ini file in notepad. If the file does not exist copy php.ini-development to php.ini and open it in notepad. Then uncomment the following line:

extension_dir = "ext"

Step 3: Configure apache

Open xampp control panel, click config button for apache, and click Apache (httpd-xampp.conf). A text file will open up put the following settings at the bottom of the file:

ScriptAlias /php56 "C:/xampp/php56"
Action application/x-httpd-php56-cgi /php56/php-cgi.exe
<Directory "C:/xampp/php56">
    AllowOverride None
    Options None
    Require all denied
    <Files "php-cgi.exe">
        Require all granted
    </Files>
</Directory>

Note: You can add more versions of PHP to your xampp installation following step 1 to 3 if you want.

Step 4 (option 1): [Add Directories to run specific PHP version]

Now you can set directories that will run in PHP 5.6. Just add the following at the bottom of the config file (httpd-xampp.conf from Step 3) to set directories.

<Directory "C:\xampp\htdocs\my_old_project1">
    <FilesMatch "\.php$">
        SetHandler application/x-httpd-php56-cgi
    </FilesMatch>
</Directory>

<Directory "C:\xampp\htdocs\my_old_project2">
    <FilesMatch "\.php$">
        SetHandler application/x-httpd-php56-cgi
    </FilesMatch>
</Directory>

Step 4 (option 2): [Run older PHP version on a separate port]

Now to to set PHP v5.6 to port 8056 add the following code to the bottom of the config file (httpd-xampp.conf from Step 3).

Listen 8056
<VirtualHost *:8056>
    <FilesMatch "\.php$">
        SetHandler application/x-httpd-php56-cgi
    </FilesMatch>
</VirtualHost>

Step 4 (option 3): [Run an older PHP version on a virtualhost]

To create a virtualhost (localhost56) on a directory (htdocs56) to use PHP v5.6 on http://localhost56, create directory htdocs56 at your desired location and add localhost56 to your hosts file (see how), then add the following code to the bottom of the config file (httpd-xampp.conf from Step 3).

<VirtualHost localhost56:80>
    DocumentRoot "C:\xampp\htdocs56"
    ServerName localhost56
    <Directory "C:\xampp\htdocs56">
        Require all granted    
    </Directory>
    <FilesMatch "\.php$">
        SetHandler application/x-httpd-php56-cgi
    </FilesMatch>
</VirtualHost>

Finish: Save and Restart Apache

Save and close the config file, Restart apache from xampp control panel. If you went for option 2 you can see the additional port(8056) listed in your xampp control panel.

Update for Error:
malformed header from script 'php-cgi.exe': Bad header

If you encounter the above error, open httpd-xampp.conf again and comment out the following line with a leading # (hash character).

SetEnv PHPRC "\\path\\to\\xampp\\php"

I was getting this error too, although my issue was that I kept switching between two corporate networks via my Virtual Machine, with different access credentials. I had to run the command prompt:

ipconfig /renew

After this my network issues were resolved and I could connect once again to SQL.

I put the following javascript in the page header and it seems to work. It detects when the browser does not support showModalDialog and attaches a custom method that uses window.open, parses the dialog specs (height, width, scroll, etc.), centers on opener and sets focus back to the window (if focus is lost). Also, it uses the URL as the window name so that a new window is not opened each time. If you are passing window args to the modal you will need to write some additional code to fix that. The popup is not modal but at least you don't have to change a lot of code. Might need some work for your circumstances.

<script type="text/javascript">
  // fix for deprecated method in Chrome 37
  if (!window.showModalDialog) {
     window.showModalDialog = function (arg1, arg2, arg3) {

        var w;
        var h;
        var resizable = "no";
        var scroll = "no";
        var status = "no";

        // get the modal specs
        var mdattrs = arg3.split(";");
        for (i = 0; i < mdattrs.length; i++) {
           var mdattr = mdattrs[i].split(":");

           var n = mdattr[0];
           var v = mdattr[1];
           if (n) { n = n.trim().toLowerCase(); }
           if (v) { v = v.trim().toLowerCase(); }

           if (n == "dialogheight") {
              h = v.replace("px", "");
           } else if (n == "dialogwidth") {
              w = v.replace("px", "");
           } else if (n == "resizable") {
              resizable = v;
           } else if (n == "scroll") {
              scroll = v;
           } else if (n == "status") {
              status = v;
           }
        }

        var left = window.screenX + (window.outerWidth / 2) - (w / 2);
        var top = window.screenY + (window.outerHeight / 2) - (h / 2);
        var targetWin = window.open(arg1, arg1, 'toolbar=no, location=no, directories=no, status=' + status + ', menubar=no, scrollbars=' + scroll + ', resizable=' + resizable + ', copyhistory=no, width=' + w + ', height=' + h + ', top=' + top + ', left=' + left);
        targetWin.focus();
     };
  }

bootstrap provides various classes for table

 <table class="table"></table>
 <table class="table table-bordered"></table>
 <table class="table table-hover"></table>
 <table class="table table-condensed"></table>
 <table class="table table-responsive"></table>

Or you can do

s = Character.toUpperCase(s.charAt(0)) + s.substring(1); 

You can do this way:

if($(selector).filter('.class1, .class2').length){
    // Or logic
}

if($(selector).filter('.class1, .class2').length){
    // And logic
}

In OpenGL you don't create objects, you just draw them. Once they are drawn, OpenGL no longer cares about what geometry you sent it.

glutSolidSphere is just sending drawing commands to OpenGL. However there's nothing special in and about it. And since it's tied to GLUT I'd not use it. Instead, if you really need some sphere in your code, how about create if for yourself?

Use an on onkeypress event. Example for a zip code box. It allows a maximum of 5 characters, and checks to make sure input is only numbers.

Nothing beats a server side validation of course, but this is a nifty way to go.

function validInput(e) {_x000D_
  e = (e) ? e : window.event;_x000D_
  a = document.getElementById('zip-code');_x000D_
  cPress = (e.which) ? e.which : e.keyCode;_x000D_
_x000D_
  if (cPress > 31 && (cPress < 48 || cPress > 57)) {_x000D_
    return false;_x000D_
  } else if (a.value.length >= 5) {_x000D_
    return false;_x000D_
  }_x000D_
_x000D_
  return true;_x000D_
}

#zip-code {_x000D_
  overflow: hidden;_x000D_
  width: 60px;_x000D_
}

<label for="zip-code">Zip Code:</label>_x000D_
<input type="number" id="zip-code" name="zip-code" onkeypress="return validInput(event);" required="required">

I used the code mentioned in this great answer and expanded it to support 2 additional parameters which I needed in my case. The parameters are file extensions to filter on and a flag indicating whether to concatenate the full path to the name of the file or not.

I hope it is clear enough and someone will finds it beneficial.

function fileList = getAllFiles(dirName, fileExtension, appendFullPath)

  dirData = dir([dirName '/' fileExtension]);      %# Get the data for the current directory
  dirWithSubFolders = dir(dirName);
  dirIndex = [dirWithSubFolders.isdir];  %# Find the index for directories
  fileList = {dirData.name}';  %'# Get a list of the files
  if ~isempty(fileList)
    if appendFullPath
      fileList = cellfun(@(x) fullfile(dirName,x),...  %# Prepend path to files
                       fileList,'UniformOutput',false);
    end
  end
  subDirs = {dirWithSubFolders(dirIndex).name};  %# Get a list of the subdirectories
  validIndex = ~ismember(subDirs,{'.','..'});  %# Find index of subdirectories
                                               %#   that are not '.' or '..'
  for iDir = find(validIndex)                  %# Loop over valid subdirectories
    nextDir = fullfile(dirName,subDirs{iDir});    %# Get the subdirectory path
    fileList = [fileList; getAllFiles(nextDir, fileExtension, appendFullPath)];  %# Recursively call getAllFiles
  end

end

Example for running the code:

fileList = getAllFiles(dirName, '*.xml', 0); %#0 is false obviously

Structs can have functions just like classes. The only difference is that they are public by default:

struct A {
    void f() {}
};

Additionally, structs can also have constructors and destructors.

struct A {
    A() : x(5) {}
    ~A() {}

    private: int x;
};

You need to define height of ul or your div and set overflow equals to auto as below:

<ul style="width: 300px; height: 200px; overflow: auto">
  <li>text</li>
  <li>text</li>

If you want to keep the constants in the React component, use statics property, like the example below. Otherwise, use the answer given by @Jim

var MyComponent = React.createClass({
    statics: {
        sizeToLetterMap: {
            small_square: 's',
            large_square: 'q',
            thumbnail: 't',
            small_240: 'm',
            small_320: 'n',
            medium_640: 'z',
            medium_800: 'c',
            large_1024: 'b',
            large_1600: 'h',
            large_2048: 'k',
            original: 'o'
        },
        someOtherStatic: 100
    },

    photoUrl: function (image, size_text) {
        var size = MyComponent.sizeToLetterMap[size_text];
    }

Well if you're happy printing it in decimal, you could just make it positive by masking:

int positive = bytes[i] & 0xff;

If you're printing out a hash though, it would be more conventional to use hex. There are plenty of other questions on Stack Overflow addressing converting binary data to a hex string in Java.

You can select directly into the variable rather than using set:

DECLARE @times int

SELECT @times = COUNT(DidWin)
FROM thetable
WHERE DidWin = 1 AND Playername='Me'

If you need to set multiple variables you can do it from the same select (example a bit contrived):

DECLARE @wins int, @losses int

SELECT @wins = SUM(DidWin), @losses = SUM(DidLose)
FROM thetable
WHERE Playername='Me'

If you are partial to using set, you can use parentheses:

DECLARE @wins int, @losses int

SET (@wins, @losses) = (SELECT SUM(DidWin), SUM(DidLose)
FROM thetable
WHERE Playername='Me');

Use regex:

result = result.replaceAll("\n.*", "");

replaceAll() uses regex to find its target, which I have replaced with "nothing" - effectively deleting the target.

The target I've specified by the regex \n.* means "the newline char and everything after"

ThiefMaster's answer is 100% correct, although I came across a similar problem where I needed to fetch a property from a nested object (object within an object), so as an alternative to his answer, you can create a recursive solution that will allow you to define a nomenclature to grab any property, regardless of depth:

function fetchFromObject(obj, prop) {

    if(typeof obj === 'undefined') {
        return false;
    }

    var _index = prop.indexOf('.')
    if(_index > -1) {
        return fetchFromObject(obj[prop.substring(0, _index)], prop.substr(_index + 1));
    }

    return obj[prop];
}

Where your string reference to a given property ressembles property1.property2

To write an equivalent method using iteration, we must explicitly use a stack. The fact that the iterative version requires a stack for its solution indicates that the problem is difficult enough that it can benefit from recursion. As a general rule, recursion is most suitable for problems that cannot be solved with a fixed amount of memory and consequently require a stack when solved iteratively. Having said that, recursion and iteration can show the same outcome while they follow different pattern.To decide which method works better is case by case and best practice is to choose based on the pattern that problem follows.

For example, to find the nth triangular number of Triangular sequence: 1 3 6 10 15 … A program that uses an iterative algorithm to find the n th triangular number:

Using an iterative algorithm:

//Triangular.java
import java.util.*;
class Triangular {
   public static int iterativeTriangular(int n) {
      int sum = 0;
      for (int i = 1; i <= n; i ++)
         sum += i;
      return sum;
   }
   public static void main(String args[]) {
      Scanner stdin = new Scanner(System.in);
      System.out.print("Please enter a number: ");
      int n = stdin.nextInt();
      System.out.println("The " + n + "-th triangular number is: " + 
                            iterativeTriangular(n));
   }
}//enter code here

Using a recursive algorithm:

//Triangular.java
import java.util.*;
class Triangular {
   public static int recursiveTriangular(int n) {
      if (n == 1)
     return 1;  
      return recursiveTriangular(n-1) + n; 
   }

   public static void main(String args[]) {
      Scanner stdin = new Scanner(System.in);
      System.out.print("Please enter a number: ");
      int n = stdin.nextInt();
      System.out.println("The " + n + "-th triangular number is: " + 
                             recursiveTriangular(n)); 
   }
}

By Using map

var values = $("input[name='pname[]']")
              .map(function(){return $(this).val();}).get();

The possibilities for this error are overwhelming.

In my case, I found that the issue was adding the homepage filed in package.json caused the issue.

Worth checking: in package.json change:

homepage: "www.example.com"

to

hompage: ""   

You're deleting the row from the gridview and then rebinding it to the datasource (which still contains the row). Either delete the row from the datasource, or don't rebind the gridview afterwards.

It's simple. Just add:

PictureBox1.BackgroundImageLayout = ImageLayout.Zoom;

In my case, I removed web.config file from Views folder by accident. I added it back , and it was OK.

Value of %TEMP% environment variable is often user-specific and Windows sets it up with regard to currently logged in user account. Some user accounts may have no user profile, for example when your process runs as a service on SYSTEM, LOCALSYSTEM or other built-in account, or is invoked by IIS application with AppPool identity with Create user profile option disabled. So even when you do not overwrite %TEMP% variable explicitly, Windows may use c:\temp or even c:\windows\temp folders for, lets say, non-usual user accounts. And what's more important, process might have no access rights to this directory!

Like Apache, this is a quick edit to the source and recompile. From Calomel.org:

The Server: string is the header which is sent back to the client to tell them what type of http server you are running and possibly what version. This string is used by places like Alexia and Netcraft to collect statistics about how many and of what type of web server are live on the Internet. To support the author and statistics for Nginx we recommend keeping this string as is. But, for security you may not want people to know what you are running and you can change this in the source code. Edit the source file src/http/ngx_http_header_filter_module.c at look at lines 48 and 49. You can change the String to anything you want.

## vi src/http/ngx_http_header_filter_module.c (lines 48 and 49)
static char ngx_http_server_string[] = "Server: MyDomain.com" CRLF;
static char ngx_http_server_full_string[] = "Server: MyDomain.com" CRLF;

March 2011 edit: Props to Flavius below for pointing out a new option, replacing Nginx's standard HttpHeadersModule with the forked HttpHeadersMoreModule. Recompiling the standard module is still the quick fix, and makes sense if you want to use the standard module and won't be changing the server string often. But if you want more than that, the HttpHeadersMoreModule is a strong project and lets you do all sorts of runtime black magic with your HTTP headers.

You don't need the quotes.

<a style={{backgroundColor: bgColors.Yellow}}>yellow</a>

After checking all of these answers above without luck, the folling code worked for me to solve the problem:

$(".ui-dialog").dialog("close");

Maybe this will be also a good try if you seek for alternatives.

You can use the Logical NOT ! operator:

if (!$(this).parent().next().is('ul')){

Or equivalently (see comments below):

if (! ($(this).parent().next().is('ul'))){

For more information, see the Logical Operators section of the MDN docs.

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

Thats work for me:

var jsScripts = [];

jsScripts.push("/js/script1.js" );
jsScripts.push("/js/script2.js" );
jsScripts.push("/js/script3.js" );

$(jsScripts).each(function( index, value ) {
    $.holdReady( true );
    $.getScript( value ).done(function(script, status) {
        console.log('Loaded ' + index + ' : ' + value + ' (' + status + ')');                
        $.holdReady( false );
    });
});

Other configurable Spark option relating to jars and classpath, in case of yarn as deploy mode are as follows
From the spark documentation,

spark.yarn.jars

List of libraries containing Spark code to distribute to YARN containers. By default, Spark on YARN will use Spark jars installed locally, but the Spark jars can also be in a world-readable location on HDFS. This allows YARN to cache it on nodes so that it doesn't need to be distributed each time an application runs. To point to jars on HDFS, for example, set this configuration to hdfs:///some/path. Globs are allowed.

spark.yarn.archive

An archive containing needed Spark jars for distribution to the YARN cache. If set, this configuration replaces spark.yarn.jars and the archive is used in all the application's containers. The archive should contain jar files in its root directory. Like with the previous option, the archive can also be hosted on HDFS to speed up file distribution.

Users can configure this parameter to specify their jars, which inturn gets included in Spark driver's classpath.

Use aggregation on name and get name with count > 1:

db.collection.aggregate([
    {"$group" : { "_id": "$name", "count": { "$sum": 1 } } },
    {"$match": {"_id" :{ "$ne" : null } , "count" : {"$gt": 1} } }, 
    {"$project": {"name" : "$_id", "_id" : 0} }
]);

To sort the results by most to least duplicates:

db.collection.aggregate([
    {"$group" : { "_id": "$name", "count": { "$sum": 1 } } },
    {"$match": {"_id" :{ "$ne" : null } , "count" : {"$gt": 1} } }, 
    {"$sort": {"count" : -1} },
    {"$project": {"name" : "$_id", "_id" : 0} }     
]);

To use with another column name than "name", change "$name" to "$column_name"

This exception could point to the LINQ parameter that is named source:

 System.Linq.Enumerable.Select[TSource,TResult](IEnumerable`1 source, Func`2 selector)

As the source parameter in your LINQ query (var nCounts = from sale in sal) is 'sal', I suppose the list named 'sal' might be null.
