For radio and radio group:

$(document).ready(function() {
    $(document).find("input:checked[type='radio']").addClass('bounce');   
    $("input[type='radio']").click(function() {
        $(this).prop('checked', false);
        $(this).toggleClass('bounce');

        if( $(this).hasClass('bounce') ) {
            $(this).prop('checked', true);
            $(document).find("input:not(:checked)[type='radio']").removeClass('bounce');
        }
    });
});

The third argument is the XMLHttpRequest object, so you can do whatever you want.

$.ajax({
  url  : 'http://example.com',
  type : 'post',
  data : 'a=b'
}).done(function(data, statusText, xhr){
  var status = xhr.status;                //200
  var head = xhr.getAllResponseHeaders(); //Detail header info
});

You can make it with jQuery a less lines:

$(function(){

    var requiredCheckboxes = $(':checkbox[required]');

    requiredCheckboxes.change(function(){

        if(requiredCheckboxes.is(':checked')) {
            requiredCheckboxes.removeAttr('required');
        }

        else {
            requiredCheckboxes.attr('required', 'required');
        }
    });

});

With $(':checkbox[required]') you select all checkboxes with the attribute required, then, with the .change method applied to this group of checkboxes, you can execute the function you want when any item of this group changes. In this case, if any of the checkboxes is checked, I remove the required attribute for all of the checkboxes that are part of the selected group.

I hope this helps.

The Mono project dropped Windows XP support and "forgot" to mention it. Although they still claim Windows XP SP2 is the minimum supported version, it is actually Windows Vista.

The last version of Mono to support Windows XP was 3.2.3.

Even though this is a year old question, I would like to say that using dict will not help if you have an ordered dict within the ordered dict. The simplest way that could convert those recursive ordered dict will be

import json
from collections import OrderedDict
input_dict = OrderedDict([('method', 'constant'), ('recursive', OrderedDict([('m', 'c')]))])
output_dict = json.loads(json.dumps(input_dict))
print output_dict

If you are here because of the Liquibase error saying:

Caused By: Precondition Error
...
Can't detect type of array [Ljava.lang.Short

and you are using

not {
  indexExists()
}

precondition multiple times, then you are facing an old bug: https://liquibase.jira.com/browse/CORE-1342

We can try to execute an above check using bare sqlCheck(Postgres):

SELECT COUNT(i.relname)
FROM
    pg_class t,
    pg_class i,
    pg_index ix
WHERE
    t.oid = ix.indrelid
    and i.oid = ix.indexrelid
    and t.relkind = 'r'
    and t.relname = 'tableName'
    and i.relname = 'indexName';

where tableName - is an index table name and indexName - is an index name

To be agnostic, drop back and punt.

Select a.name as a_name, r.name as r_name
  from ApplicationsResource ar, Applications a, Resources r
 where a.id = ar.app_id
   and r.id = ar.resource_id
 order by r.name, a.name;

Now user your server programming language to concatenate a_names while r_name is the same as the last time.

Here is a method that uses stamper and absolute coordinates showed in the different PDF clients (Adobe, FoxIt and etc. )

public static void AddTextToPdf(string inputPdfPath, string outputPdfPath, string textToAdd, System.Drawing.Point point)
    {
        //variables
        string pathin = inputPdfPath;
        string pathout = outputPdfPath;

        //create PdfReader object to read from the existing document
        using (PdfReader reader = new PdfReader(pathin))
        //create PdfStamper object to write to get the pages from reader 
        using (PdfStamper stamper = new PdfStamper(reader, new FileStream(pathout, FileMode.Create)))
        {
            //select two pages from the original document
            reader.SelectPages("1-2");

            //gettins the page size in order to substract from the iTextSharp coordinates
            var pageSize = reader.GetPageSize(1);

            // PdfContentByte from stamper to add content to the pages over the original content
            PdfContentByte pbover = stamper.GetOverContent(1);

            //add content to the page using ColumnText
            Font font = new Font();
            font.Size = 45;

            //setting up the X and Y coordinates of the document
            int x = point.X;
            int y = point.Y;

            y = (int) (pageSize.Height - y);

            ColumnText.ShowTextAligned(pbover, Element.ALIGN_CENTER, new Phrase(textToAdd, font), x, y, 0);
        }
    }

There is now (AutoMapper 2.0) an IgnoreMap attribute, which I'm going to use rather than the fluent syntax which is a bit heavy IMHO.

A complete solution is here

it's explained very nice with sample code. However, be careful that it does not close the application.Add the line Application.Current.Shutdown(); to gracefully close the app.

Using Ctrl+Shift+R to refresh was nice but didn't get everything I needed. still some things wouldn't refresh, such as data stored in js and css. found a solution: a toolbar of google for chrome web developers. After you install the toolbar select options and "reset page".

It works in my react project:

import FileSaver from 'file-saver';
// ...
onTestSaveFile() {
    var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
    FileSaver.saveAs(blob, "hello world.txt");
}

You can actually disable all database constraints in a single SQL command and the re-enable them calling another single command. See:

• Can foreign key constraints be temporarily disabled using TSQL?

I am currently working with SQL Server 2005 but I am almost sure that this approach worked with SQL 2000 as well

Simple and easy way to detect button event and perform some action

class youCell: UITableViewCell
{
    var yourobj : (() -> Void)? = nil

    //You can pass any kind data also.
   //var user: ((String?) -> Void)? = nil

     override func awakeFromNib()
        {
        super.awakeFromNib()
        }

 @IBAction func btnAction(sender: UIButton)
    {
        if let btnAction = self.yourobj
        {
            btnAction()
          //  user!("pass string")
        }
    }
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
    {
        let cell = youtableview.dequeueReusableCellWithIdentifier(identifier) as? youCell
        cell?.selectionStyle = UITableViewCellSelectionStyle.None

cell!. yourobj =
            {
                //Do whatever you want to do when the button is tapped here
                self.view.addSubview(self.someotherView)
        }

cell.user = { string in
            print(string)
        }

return cell

}

Because ... it (MILLISECONDS) is a static field (hiding in an enumeration, but that's what it is) ... however it is being invoked upon an instance of the given type (but see below as this isn't really true¹).

javac will "accept" that, but it should really be MyUnits.MILLISECONDS (or non-prefixed in the applicable scope).

¹ Actually, javac "rewrites" the code to the preferred form -- if m happened to be null it would not throw an NPE at run-time -- it is never actually invoked upon the instance).

Happy coding.

I'm not really seeing how the question title fits in with the rest :-) More accurate and specialized titles increase the likely hood the question/answers can benefit other programmers.

This is because you have the following code:

class JSONDeserializer
{
    Value JSONDeserializer::ParseValue(TDR type, const json_string& valueString);
};

This is not valid C++ but Visual Studio seems to accept it. You need to change it to the following code to be able to compile it with a standard compliant compiler (gcc is more compliant to the standard on this point).

class JSONDeserializer
{
    Value ParseValue(TDR type, const json_string& valueString);
};

The error come from the fact that JSONDeserializer::ParseValue is a qualified name (a name with a namespace qualification), and such a name is forbidden as a method name in a class.

You can do this with jQuery :

$(document).ready(function(){_x000D_
  _x000D_
  $('.claimedRight').each(function (f) {_x000D_

      var newstr = $(this).text().substring(0,20);_x000D_
      $(this).text(newstr);_x000D_
_x000D_
    });_x000D_
})

This is the suggested Matplotlib 3 solution from the official website HERE:

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 2*np.pi, 100)
y = np.sin(x)

ax = plt.subplot(111)
ax.plot(x, y)

# Hide the right and top spines
ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)

# Only show ticks on the left and bottom spines
ax.yaxis.set_ticks_position('left')
ax.xaxis.set_ticks_position('bottom')

plt.show()

This script will add a div that covers the entire window as the page loads. It will show a CSS-only loading spinner automatically. It will wait until the window (not the document) finishes loading, then it will wait an optional extra few seconds.

• Works with jQuery 3 (it has a new window load event)
• No image needed but it's easy to add one
• Change the delay for more branding or instructions
• Only dependency is jQuery.

The simple way to solve the problem is to use ComparisonChain from Guava http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/collect/ComparisonChain.html

private static Comparator<String> stringAlphabeticalComparator = new Comparator<String>() {
        public int compare(String str1, String str2) {
            return ComparisonChain.start().
                                compare(str1,str2, String.CASE_INSENSITIVE_ORDER).
                                compare(str1,str2).
                                result();
         }
 };
Collections.sort(list, stringAlphabeticalComparator);

The first comparator from the chain will sort strings according to the case insensitive order, and the second comparator will sort strings according to the case insensitive order. As excepted strings appear in the result according to the alphabetical order:

"AA","Aa","aa","Development","development"

?? To state the answer differently ??

In Xaml verify that there are no Missing Parent Nodes or incorrect nodes in the defined areas.

For example

This Is Failing:

There is no proper parent for the ItemsPanelTemplate child node below:

<ItemsControl ItemsSource="{Binding TimeSpanChoices}">
    <ItemsPanelTemplate>
        <UniformGrid Rows="1" />
    </ItemsPanelTemplate>
    ...
</ItemsControl>

This Is Working:

<ItemsControl ItemsSource="{Binding TimeSpanChoices}">
    <ItemsControl.ItemsPanel> <!-- I am the missing parent! -->
        <ItemsPanelTemplate>
            <UniformGrid Rows="1" />
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    ...    
</ItemsControl>

There is a proper parent node of <ItemsControl.ItemsPanel> provided^^^.

I would like to add for the sake of completeness that you can also add just the LIBRARY PATH where it will look for a dependent library (which may not be directly referenced in your code but a library you use may need it).

For comparison, this would correspond to what LIBPATH environment does but its kind of obscure in Qt Creator and not well documented.

The way i came around this is following:

LIBS += -L"$$_PRO_FILE_PWD_/Path_to_Psapi_lib/"

Essentially if you don't provide the actual library name, it adds the path to where it will search dependent libraries. The difference in syntax is small but this is very useful to supply just the PATH where to look for dependent libraries. It sometime is just a pain to supply each path individual library where you know they are all in certain folder and Qt Creator will pick them up.

I'm aware that this thread is quite old, the correct answer seems valid and there are a lot of working solutions out there, but I think the approach stated bellow might have an additional benefit regarding efficiency and elegance.

I need this behavior for all of my activities, so I created a class CustomActivity inheriting from the class Activity and "hooked" the dispatchTouchEvent function. There are mainly two conditions to take care of:

1. If focus is unchanged and someone is tapping outside of the current input field, then dismiss the IME
2. If focus has changed and the next focused element isn't an instance of any kind of an input field, then dismiss the IME

This is my result:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    if(ev.getAction() == MotionEvent.ACTION_UP) {
        final View view = getCurrentFocus();

        if(view != null) {
            final boolean consumed = super.dispatchTouchEvent(ev);

            final View viewTmp = getCurrentFocus();
            final View viewNew = viewTmp != null ? viewTmp : view;

            if(viewNew.equals(view)) {
                final Rect rect = new Rect();
                final int[] coordinates = new int[2];

                view.getLocationOnScreen(coordinates);

                rect.set(coordinates[0], coordinates[1], coordinates[0] + view.getWidth(), coordinates[1] + view.getHeight());

                final int x = (int) ev.getX();
                final int y = (int) ev.getY();

                if(rect.contains(x, y)) {
                    return consumed;
                }
            }
            else if(viewNew instanceof EditText || viewNew instanceof CustomEditText) {
                return consumed;
            }

            final InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

            inputMethodManager.hideSoftInputFromWindow(viewNew.getWindowToken(), 0);

            viewNew.clearFocus();

            return consumed;
        }
    }       

    return super.dispatchTouchEvent(ev);
}

Side note: Additionally I assign these attributes to the root view making it possible to clear focus on every input field and preventing input fields gaining focus on activity startup (making the content view the "focus catcher"):

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

    final View view = findViewById(R.id.content);

    view.setFocusable(true);
    view.setFocusableInTouchMode(true);
}

You might use a dictionary, say

Dictionary<string,object> properties;

I think in most cases where something similar is done, it's done like this.
In any case, you would not gain anything from creating a "real" property with set and get accessors, since it would be created only at run-time and you would not be using it in your code...

Here is an example, showing a possible implementation of filtering and sorting (no error checking):

using System;
using System.Collections.Generic;
using System.Linq;

namespace ConsoleApplication1 {

    class ObjectWithProperties {
        Dictionary<string, object> properties = new Dictionary<string,object>();

        public object this[string name] {
            get { 
                if (properties.ContainsKey(name)){
                    return properties[name];
                }
                return null;
            }
            set {
                properties[name] = value;
            }
        }

    }

    class Comparer<T> : IComparer<ObjectWithProperties> where T : IComparable {

        string m_attributeName;

        public Comparer(string attributeName){
            m_attributeName = attributeName;
        }

        public int Compare(ObjectWithProperties x, ObjectWithProperties y) {
            return ((T)x[m_attributeName]).CompareTo((T)y[m_attributeName]);
        }

    }

    class Program {

        static void Main(string[] args) {

            // create some objects and fill a list
            var obj1 = new ObjectWithProperties();
            obj1["test"] = 100;
            var obj2 = new ObjectWithProperties();
            obj2["test"] = 200;
            var obj3 = new ObjectWithProperties();
            obj3["test"] = 150;
            var objects = new List<ObjectWithProperties>(new ObjectWithProperties[]{ obj1, obj2, obj3 });

            // filtering:
            Console.WriteLine("Filtering:");
            var filtered = from obj in objects
                         where (int)obj["test"] >= 150
                         select obj;
            foreach (var obj in filtered){
                Console.WriteLine(obj["test"]);
            }

            // sorting:
            Console.WriteLine("Sorting:");
            Comparer<int> c = new Comparer<int>("test");
            objects.Sort(c);
            foreach (var obj in objects) {
                Console.WriteLine(obj["test"]);
            }
        }

    }
}

Example Python script returns a boolean if a string is valid json:

import json

def is_json(myjson):
  try:
    json_object = json.loads(myjson)
  except ValueError as e:
    return False
  return True

Which prints:

print is_json("{}")                          #prints True
print is_json("{asdf}")                      #prints False
print is_json('{ "age":100}')                #prints True
print is_json("{'age':100 }")                #prints False
print is_json("{\"age\":100 }")              #prints True
print is_json('{"age":100 }')                #prints True
print is_json('{"foo":[5,6.8],"foo":"bar"}') #prints True

Convert a JSON string to a Python dictionary:

import json
mydict = json.loads('{"foo":"bar"}')
print(mydict['foo'])    #prints bar

mylist = json.loads("[5,6,7]")
print(mylist)
[5, 6, 7]

Convert a python object to JSON string:

foo = {}
foo['gummy'] = 'bear'
print(json.dumps(foo))           #prints {"gummy": "bear"}

If you want access to low-level parsing, don't roll your own, use an existing library: http://www.json.org/

Great tutorial on python JSON module: https://pymotw.com/2/json/

Is String JSON and show syntax errors and error messages:

sudo cpan JSON::XS
echo '{"foo":[5,6.8],"foo":"bar" bar}' > myjson.json
json_xs -t none < myjson.json

Prints:

, or } expected while parsing object/hash, at character offset 28 (before "bar}
at /usr/local/bin/json_xs line 183, <STDIN> line 1.

json_xs is capable of syntax checking, parsing, prittifying, encoding, decoding and more:

https://metacpan.org/pod/json_xs

SELECT a AS current_a, COUNT(*) AS b,
   (SELECT COUNT(*) FROM t WHERE a = current_a AND c = 'const' ) as d
   from t group by a order by b desc

Component 2, the directive component can define a input property (@input annotation in Typescript). And Component 1 can pass that property to the directive component from template.

See this SO answer How to do inter communication between a master and detail component in Angular2?

and how input is being passed to child components. In your case it is directive.

Look here: http://www.w3schools.com/tags/tag_p.asp

The p element automatically creates some space before and after itself. The space is automatically applied by the browser, or you can specify it in a style sheet.

you could remove the extra space by using css

p {
   margin: 0px;
   padding: 0px;
}

or use the element <span> which has no default margins and is an inline element.

If you use this syntax:

<div ng-attr-id="{{ 'object-' + myScopeObject.index }}"></div>

Angular will render something like:

 <div ng-id="object-1"></div>

However this syntax:

<div id="{{ 'object-' + $index }}"></div>

will generate something like:

<div id="object-1"></div>

In python, it's called slicing. Here is an example of python's slice notation:

>>> list1 = ['a','b','c','d','e','f','g','h', 'i', 'j', 'k', 'l']
>>> print list1[:5]
['a', 'b', 'c', 'd', 'e']
>>> print list1[-7:]
['f', 'g', 'h', 'i', 'j', 'k', 'l']

Note how you can slice either positively or negatively. When you use a negative number, it means we slice from right to left.

The JRE/JDK/Java 8 jurisdiction files can be found here:

Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 8 Download

Like James said above:
Install the files in ${java.home}/jre/lib/security/.

The SCSS way for the given example, would be something like:

.something {
  display: inline
}
.else {
  background: red
}

.composite {
  @extend .something;
  @extend .else;
}

Try this JS solution that toggles webkitOverflowScrolling style. The trick here is that this style is off, mobile Safari goes to ordinary scrolling and prevents over-bounce — alas, it is not able to cancel ongoing drag. This complex solution also tracks onscroll as bounce over the top makes scrollTop negative that may be tracked. This solution was tested on iOS 12.1.1 and has single drawback: while accelerating the scroll single over-bounce still happens as resetting the style may not cancel it immediately.

function preventScrollVerticalBounceEffect(container) {
  setTouchScroll(true) //!: enable before the first scroll attempt

  container.addEventListener("touchstart", onTouchStart)
  container.addEventListener("touchmove", onTouch, { passive: false })
  container.addEventListener("touchend", onTouchEnd)
  container.addEventListener("scroll", onScroll)

  function isTouchScroll() {
    return !!container.style.webkitOverflowScrolling
  }

  let prevScrollTop = 0, prevTouchY, opid = 0

  function setTouchScroll(on) {
    container.style.webkitOverflowScrolling = on ? "touch" : null

    //Hint: auto-enabling after a small pause makes the start
    // smoothly accelerated as required. After the pause the
    // scroll position is settled, and there is no delta to
    // make over-bounce by dragging the finger. But still,
    // accelerated content makes short single over-bounce
    // as acceleration may not be off instantly.

    const xopid = ++opid
    !on && setTimeout(() => (xopid === opid) && setTouchScroll(true), 250)

    if(!on && container.scrollTop < 16)
      container.scrollTop = 0
    prevScrollTop = container.scrollTop
  }

  function isBounceOverTop() {
    const dY = container.scrollTop - prevScrollTop
    return dY < 0 && container.scrollTop < 16
  }

  function isBounceOverBottom(touchY) {
    const dY = touchY - prevTouchY

    //Hint: trying to bounce over the bottom, the finger moves
    // up the screen, thus Y becomes smaller. We prevent this.

    return dY < 0 && container.scrollHeight - 16 <=
      container.scrollTop + container.offsetHeight
  }

  function onTouchStart(e) {
    prevTouchY = e.touches[0].pageY
  }

  function onTouch(e) {
    const touchY = e.touches[0].pageY

    if(isBounceOverBottom(touchY)) {
      if(isTouchScroll())
        setTouchScroll(false)
      e.preventDefault()
    }

    prevTouchY = touchY
  }

  function onTouchEnd() {
    prevTouchY = undefined
  }

  function onScroll() {
    if(isTouchScroll() && isBounceOverTop()) {
      setTouchScroll(false)
    }
  }
}

You have ArrayList all wrong,

• You can't have an integer array and assign a string value.
• You cannot do a add() method in an array

Rather do this:

List<String> alist = new ArrayList<String>();
alist.add("apple");
alist.add("banana");
alist.add("orange");

String value = alist.get(1); //returns the 2nd item from list, in this case "banana"

Indexing is counted from 0 to N-1 where N is size() of list.

while spring.jpa.open-in-view was true, I didn't have any problem with getOne but after setting it to false , i got LazyInitializationException. Then problem was solved by replacing with findById.
Although there is another solution without replacing the getOne method, and that is put @Transactional at method which is calling repository.getOne(id). In this way transaction will exists and session will not be closed in your method and while using entity there would not be any LazyInitializationException.

One tested solution for Bootstrap 4 beta:

.popover {
        min-width: 30em !important;
    }

Together with the jQuery statement:

$('[data-toggle="popover"]').popover({
      container: 'body',
      trigger: 'focus',
      html: true,
      placement: 'top'
    })

Side-note, data-container="body" or container: "body" in either HTML or as an option to the popover({}) object didn't really do the trick [maybe the do work but only together with the CSS statement];

Also, remember that Bootstrap 4 beta relies on popper.js for its popover and tooltip positioning (prior to that it was tether.js)

API level is basically the Android version. Instead of using the Android version name (eg 2.0, 2.3, 3.0, etc) an integer number is used. This number is increased with each version. Android 1.6 is API Level 4, Android 2.0 is API Level 5, Android 2.0.1 is API Level 6, and so on.

I would like to share an awesome answer, it might be helpful. Credits Bill Karwin see here https://dba.stackexchange.com/questions/6598/innodb-create-table-error-row-size-too-large

They vary by InnoDB file format.At present there are 2 formats called Antelope and Barracuda.

The central tablespace file (ibdata1) is always in Antelope format. If you use file-per-table, you can make the individual files use Barracuda format by setting innodb_file_format=Barracuda in my.cnf.

Basic points:

1. One 16KB page of InnoDB data must hold at least two rows of data. Plus each page has a header and a footer containing page checksums and log sequence number and so on. That's where you get your limit of a bit less than 8KB per row.

2. Fixed-size data types like INTEGER, DATE, FLOAT, CHAR are stored on this primary data page and count toward the row size limit.

3. Variable-sized data types like VARCHAR, TEXT, BLOB are stored on overflow pages, so they don't count fully toward the row size limit. In Antelope, up to 768 bytes of such columns are stored on the primary data page in addition to being stored on the overflow page. Barracuda supports a dynamic row format, so it may store only a 20-byte pointer on the primary data page.

4. Variable-size data types are also prefixed with 1 or more bytes to encode the length. And InnoDB row format also has an array of field offsets. So there's an internal structure more or less documented in their wiki.

Barracuda also supports a ROW_FORMAT=COMPRESSED to gain further storage efficiency for overflow data.

I also have to comment that I've never seen a well-designed table exceed the row size limit. It's a strong "code smell" that you're violating the repeating groups condition of First Normal Form.

Learn to use else.

Since value will never be equal to two unequal strings at once, there are only 5 possible outcomes -- one for each value you care about, plus one for "none of the above". But because your code doesn't eliminate the tests that can't pass, it has 16 "possible" paths (2 ^ the number of tests), of which most will never be followed.

With else, the only paths that exist are the 5 that can actually happen.

String value = some methodx;
if ("apple".equals(value )) {
    method1;
}
else if ("carrot".equals(value )) {
    method2;
}
else if ("mango".equals(value )) {
    method3;
}
else if ("orance".equals(value )) {
    method4;
}

Or start using JDK 7, which includes the ability to use strings in a switch statement. Course, Java will just compile the switch into an if/else like construct anyway...

const int * ptr;

means that the pointed data is constant and immutable but the pointer is not.

int * const ptr;

means that the pointer is constant and immutable but the pointed data is not.

In my case, this was due to my library not being configured as 'android'. E.g. apply plugin:'java' instead of apply plugin:'com.android.library'

You can resolve this problem by adding nodemon to your package.json:

npm install nodemon --save-dev

The problem happens when nodemon does not exist in /node_modules/.bin.

Added --save-dev since it's required during development only.

Depends on why you want to rate limit.

If it's to protect against overloading the server, it actually makes sense to put NGINX in front of it, and configure rate limiting there. It makes sense because NGINX uses much less resources, something like a few MB per ten thousand connections. So, if the server is flooded, NGINX will do the rate limiting(using an insignificant amount of resources) and only pass the allowed traffic to Apache.

If all you're after is simplicity, then use something like mod_evasive.

As usual, if it's to protect against DDoS or DoS attacks, use a service like Cloudflare which also has rate limiting.

The best way is to check the type, because undefined/null/false are a tricky thing in JS. So:

if(typeof obj !== "undefined") {
    // obj is a valid variable, do something here.
}

Note that typeof always returns a string, and doesn't generate an error if the variable doesn't exist at all.

If your subplots also have titles, you may need to adjust the main title size:

plt.suptitle("Main Title", size=16)

[ round(x,2) for x in [2.15295647e+01, 8.12531501e+00, 3.97113829e+00, 1.00777250e+01]]

Sharepoint Lists automatically have an column with "ID" which auto increments. You simply need to select this column from the "modify view" screen to view it.

I have found a solution. It is just a workaround to my problem but currently the only solution.

I was missing System.Data.Entity dll reference and problem was solved

The previous answers relate to the situation where the view controller that should present a view 1) has not been added yet to the view hierarchy, or 2) is not the top view controller.
Another possibility is that an alert should be presented while another alert is already presented, and not yet dismissed.

Do keep in mind that you don't need a stable sort if you compare all members. The 2.0 solution, as requested, can look like this:

 public void SortList() {
     MyList.Sort(delegate(MyClass a, MyClass b)
     {
         int xdiff = a.x.CompareTo(b.x);
         if (xdiff != 0) return xdiff;
         else return a.y.CompareTo(b.y);
     });
 }

Do note that this 2.0 solution is still preferable over the popular 3.5 Linq solution, it performs an in-place sort and does not have the O(n) storage requirement of the Linq approach. Unless you prefer the original List object to be untouched of course.

The answer by Craig Ringer is correct. Here's a little more info for Postgres 9.1 and later…

You can only install an extension if it has already been built for your Postgres installation (your cluster in Postgres lingo). For example, I found the uuid-ossp extension included as part of the installer for Mac OS X kindly provided by EnterpriseDB.com. Any of a few dozen extensions may be available.

To see if the uuid-ossp extension is available in your Postgres cluster, run this SQL to query the pg_available_extensions system catalog:

SELECT * FROM pg_available_extensions;

Install Extension

To install that UUID-related extension, use the CREATE EXTENSION command as seen in this this SQL:

CREATE EXTENSION IF NOT EXISTS "uuid-ossp";

Beware: I found the QUOTATION MARK characters around extension name to be required, despite documentation to the contrary.

The SQL standards committee or Postgres team chose an odd name for that command. To my mind, they should have chosen something like "INSTALL EXTENSION" or "USE EXTENSION".

Verify Installation

You can verify the extension was successfully installed in the desired database by running this SQL to query the pg_extension system catalog:

SELECT * FROM pg_extension;

UUID as default value

For more info, see the Question: Default value for UUID column in Postgres

The Old Way

The information above uses the new Extensions feature added to Postgres 9.1. In previous versions, we had to find and run a script in a .sql file. The Extensions feature was added to make installation easier, trading a bit more work for the creator of an extension for less work on the part of the user/consumer of the extension. See my blog post for more discussion.

Types of UUIDs

By the way, the code in the Question calls the function uuid_generate_v4(). This generates a type known as Version 4 where nearly all of the 128 bits are randomly generated. While this is fine for limited use on smaller set of rows, if you want to virtually eliminate any possibility of collision, use another "version" of UUID.

For example, the original Version 1 combines the MAC address of the host computer with the current date-time and an arbitrary number, the chance of collisions is practically nil.

For more discussion, see my Answer on related Question.

I also got the same exception:

I tried the following steps:

1. In Eclipse> Project > Clean. (The Exception remained)

2. I ran another project(The testng.xml ran successfully)

After running another project, I ran the project in which I was getting the Exception, and fortunately it worked for me, with no errors.

For future Googlers, If you get an error similar below after you trigger click for a polygon

"Uncaught TypeError: Cannot read property 'vertex' of undefined"

then try the code below

google.maps.event.trigger(polygon, "click", {});

Use " instead of " to escape it.

web.config is an XML file so you should use XML escaping.

connectionString="Server=dbsrv;User ID=myDbUser;Password=somepass"word"

See this forum thread.

Update:

" should work, but as it doesn't, have you tried some of the other string escape sequences for .NET? \" and ""?

Update 2:

Try single quotes for the connectionString:

connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'

Or:

connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'

Update 3:

From MSDN (SqlConnection.ConnectionString Property):

To include values that contain a semicolon, single-quote character, or double-quote character, the value must be enclosed in double quotation marks. If the value contains both a semicolon and a double-quote character, the value can be enclosed in single quotation marks.

So:

connectionString="Server=dbsrv;User ID=myDbUser;Password='somepass"word'"

The issue is not with web.config, but the format of the connection string. In a connection string, if you have a " in a value (of the key-value pair), you need to enclose the value in '. So, while Password=somepass"word does not work, Password='somepass"word' does.

Tried everything possible.. here is final piece of working code. Hope it helps someone who is looking for it.

I have experienced the same situation I did the below as this much easier. By passing commit-Id you can reach to the particular commit you want to go:

git reset --hard {commit-id}

As you want to remove your last commit so you need to pass the commit-Id where you need to move your pointer:

git reset --hard db0c078d5286b837532ff5e276dcf91885df2296

Basically I was trying to get my code to have a middle section on a 'row' to auto-adjust to the content on both sides (in my case, a dotted line separator). Like @Michael_B suggested, the key is using display:flex on the row container and at least making sure your middle container on the row has a flex-grow value of at least 1 higher than the outer containers (if outer containers don't have any flex-grow properties applied, middle container only needs 1 for flex-grow).

Here's a pic of what I was trying to do and sample code for how I solved it.

.row {
  background: lightgray;
  height: 30px;
  width: 100%;
  display: flex;
  align-items:flex-end;
  margin-top:5px;
}
.left {
  background:lightblue;
}
.separator{
  flex-grow:1;
  border-bottom:dotted 2px black;
}
.right {
  background:coral;
}

<div class="row">
  <div class="left">Left</div>
  <div class="separator"></div>
  <div class="right">Right With Text</div>
</div>
<div class="row">
  <div class="left">Left With More Text</div>
  <div class="separator"></div>
  <div class="right">Right</div>
</div>
<div class="row">
  <div class="left">Left With Text</div>
  <div class="separator"></div>
  <div class="right">Right With More Text</div>
</div>

For Python 3

Remove the rb argument and use either r or don't pass argument (default read mode).

with open( <path-to-file>, 'r' ) as theFile:
    reader = csv.DictReader(theFile)
    for line in reader:
        # line is { 'workers': 'w0', 'constant': 7.334, 'age': -1.406, ... }
        # e.g. print( line[ 'workers' ] ) yields 'w0'
        print(line)

For Python 2

import csv
with open( <path-to-file>, "rb" ) as theFile:
    reader = csv.DictReader( theFile )
    for line in reader:
        # line is { 'workers': 'w0', 'constant': 7.334, 'age': -1.406, ... }
        # e.g. print( line[ 'workers' ] ) yields 'w0'

Python has a powerful built-in CSV handler. In fact, most things are already built in to the standard library.

You can use stristr() or strpos(). Both return false if nothing is found.

1. SQL or Structured Query Language was developed by IBM for their product "System R".

Later ANSI made it as a Standard on which all Query Languages are based upon and have extended this to create their own DataBase Query Language suits. The first standard was SQL-86 and latest being SQL:2016

2. T-SQL or Transact-SQL was developed by Sybase and later co-owned by Microsoft SQL Server.

3. PL/SQL or Procedural Language/SQL was Oracle Database, known as "Relation Software" that time.

I've documented this in my blog post.

Use below command to change log level while submitting application using spark-submit or spark-sql:

spark-submit \
--conf "spark.driver.extraJavaOptions=-Dlog4j.configuration=file:<file path>/log4j.xml" \
--conf "spark.executor.extraJavaOptions=-Dlog4j.configuration=file:<file path>/log4j.xml"

Note: replace <file path> where log4j config file is stored.

Log4j.properties:

log4j.rootLogger=ERROR, console

# set the log level for these components
log4j.logger.com.test=DEBUG
log4j.logger.org=ERROR
log4j.logger.org.apache.spark=ERROR
log4j.logger.org.spark-project=ERROR
log4j.logger.org.apache.hadoop=ERROR
log4j.logger.io.netty=ERROR
log4j.logger.org.apache.zookeeper=ERROR

# add a ConsoleAppender to the logger stdout to write to the console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
# use a simple message format
log4j.appender.console.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

log4j.xml

<?xml version="1.0" encoding="UTF-8" ?>_x000D_

Switch to FileAppender in log4j.xml if you want to write logs to file instead of console. LOG_DIR is a variable for logs directory which you can supply using spark-submit --conf "spark.driver.extraJavaOptions=-D.

<appender name="file" class="org.apache.log4j.DailyRollingFileAppender">_x000D_
        <param name="file" value="${LOG_DIR}"/>_x000D_
        <param name="datePattern" value="'.'yyyy-MM-dd"/>_x000D_
        <layout class="org.apache.log4j.PatternLayout">_x000D_
            <param name="ConversionPattern" value="%d [%t] %-5p %c %x - %m%n"/>_x000D_
        </layout>_x000D_
    </appender>

Another important thing to understand here is, when job is launched in distributed mode ( deploy-mode cluster and master as yarn or mesos) the log4j configuration file should exist on driver and worker nodes (log4j.configuration=file:<file path>/log4j.xml) else log4j init will complain-

log4j:ERROR Could not read configuration file [log4j.properties]. java.io.FileNotFoundException: log4j.properties (No such file or directory)

Hint on solving this problem-

Keep log4j config file in distributed file system(HDFS or mesos) and add external configuration using log4j PropertyConfigurator. or use sparkContext addFile to make it available on each node then use log4j PropertyConfigurator to reload configuration.

In my Ubuntu machine sessions are stored at

/var/lib/php/sessions

and you have to sudo ls in this directory only ls it will throw

ls: cannot open directory '.': Permission denied

And on my Windows Wamp server php sessions are stored in

C:\wamp64\tmp

and if you install standalone php on windows then there is no value set by default

session.save_path => no value => no value

Because they're measuring different things.

Propagation delay is how long it takes one bit to travel from one end of the "wire" to the other (it's proportional to the length of the wire, crudely).

Transmission delay is how long it takes to get all the bits into the wire in the first place (it's packet_length/data_rate).

This solution is done using boto3 and Python:

import boto3
import json

invokeLambda = boto3.client('lambda', region_name='eu-west-1')

def lambda_handler(event, context):
    invokeLambda.invoke(FunctionName = 'function_name', InvocationType = 'RequestResponse', Payload = json.dumps(event))

    return True

If anyone try to capitalize the every word separate by space...

CREATE FUNCTION response(name VARCHAR(40)) RETURNS VARCHAR(200) DETERMINISTIC
BEGIN
   set @m='';
   set @c=0;
   set @l=1;
   while @c <= char_length(name)-char_length(replace(name,' ','')) do
      set @c = @c+1;
      set @p = SUBSTRING_INDEX(name,' ',@c);
      set @k = substring(name,@l,char_length(@p)-@l+1);
      set @l = char_length(@k)+2;
      set @m = concat(@m,ucase(left(@k,1)),lcase(substring(@k,2)),' ');
   end while;
   return trim(@m); 
END;
CREATE PROCEDURE updateNames()
BEGIN
  SELECT response(name) AS name FROM names;
END;

You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.

So if you want to use your code, you could do:

df = DataFrame(eval(data))

But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:

data = []
for row in result_set:
    data.append({'value': row["tag_expression"], 'key': row["tag_name"]})

But probably even this is not needed, as depending on what is exactly in your result_set you could probably:

• provide this directly to a DataFrame: DataFrame(result_set)
• or use the pandas read_sql_query function to do this for you (see docs on this)

This is the actual usage limit that google allows before you get the error mentioned in the comments, if it's a once in a lifetime pdf that the user will open in app then i feel its completely safe. Although it is advised to to follow the the native approach using the built in framework in Android from Android 5.0 / Lollipop, it's called PDFRenderer.

You should use formControlName="surveyType" on an input and not on a div

I just came back to this issue after a while, and decided to publish a plugin based on the answer by Aaron Mast.

https://www.npmjs.com/package/mongoose-recursive-upsert

Use it as a mongoose plugin. It sets up a static method which will recursively merge the object passed in.

Model.upsert({unique: 'value'}, updateObject});

I tried to work with all the suggested answers above but nothing seems to work for me. So i am trying to explain what worked for me here.

I believe if you are calling some method like the Main below or even with a single parameter as in your question, you just have to change the type of parameter from string to object for this to work. I have a class like below

//Assembly.dll
namespace TestAssembly{
    public class Main{

        public void Hello()
        { 
            var name = Console.ReadLine();
            Console.WriteLine("Hello() called");
            Console.WriteLine("Hello" + name + " at " + DateTime.Now);
        }

        public void Run(string parameters)
        { 
            Console.WriteLine("Run() called");
            Console.Write("You typed:"  + parameters);
        }

        public string TestNoParameters()
        {
            Console.WriteLine("TestNoParameters() called");
            return ("TestNoParameters() called");
        }

        public void Execute(object[] parameters)
        { 
            Console.WriteLine("Execute() called");
           Console.WriteLine("Number of parameters received: "  + parameters.Length);

           for(int i=0;i<parameters.Length;i++){
               Console.WriteLine(parameters[i]);
           }
        }

    }
}

Then you have to pass the parameterArray inside an object array like below while invoking it. The following method is what you need to work

private void ExecuteWithReflection(string methodName,object parameterObject = null)
{
    Assembly assembly = Assembly.LoadFile("Assembly.dll");
    Type typeInstance = assembly.GetType("TestAssembly.Main");

    if (typeInstance != null)
    {
        MethodInfo methodInfo = typeInstance.GetMethod(methodName);
        ParameterInfo[] parameterInfo = methodInfo.GetParameters();
        object classInstance = Activator.CreateInstance(typeInstance, null);

        if (parameterInfo.Length == 0)
        {
            // there is no parameter we can call with 'null'
            var result = methodInfo.Invoke(classInstance, null);
        }
        else
        {
            var result = methodInfo.Invoke(classInstance,new object[] { parameterObject } );
        }
    }
}

This method makes it easy to invoke the method, it can be called as following

ExecuteWithReflection("Hello");
ExecuteWithReflection("Run","Vinod");
ExecuteWithReflection("TestNoParameters");
ExecuteWithReflection("Execute",new object[]{"Vinod","Srivastav"});

you may need to check whether the settings.xml file is correct. such as user name, password, third party url.

Your problem might be here:

OR
                        (
                            SELECT m.ResourceNo FROM JobMember m
                            JOIN JobTask t ON t.JobTaskNo = m.JobTaskNo
                            WHERE t.TaskManagerNo = @UserResourceNo
                            OR
                            t.AlternateTaskManagerNo = @UserResourceNo
                        )

try changing to

OR r.ResourceNo IN
                        (
                            SELECT m.ResourceNo FROM JobMember m
                            JOIN JobTask t ON t.JobTaskNo = m.JobTaskNo
                            WHERE t.TaskManagerNo = @UserResourceNo
                            OR
                            t.AlternateTaskManagerNo = @UserResourceNo
                        )

You don't need to explicitly use qualifiers like item.photo == '' or item.photo != ''. Like in JavaScript, an empty string will be evaluated as false.

Your views will be much cleaner and readable as well.

<div ng-app init="item = {photo: ''}">_x000D_

   <div ng-if="!item.photo"> show if photo is empty</div>_x000D_
  _x000D_
   <input type=text ng-model="item.photo" placeholder="photo" />_x000D_
</div

You may directly write into your css file like this :

.content {_x000D_
  position: absolute;_x000D_
  top: 50%;_x000D_
  left:50%;_x000D_
  transform: translate(-50%,-50%);_x000D_
  }

<div class = "content" >_x000D_
  _x000D_
   <p> some text </p>_x000D_
  </div>

byte[] IntToByteArray( int data ) {    
    byte[] result = new byte[4];
    result[0] = (byte) ((data & 0xFF000000) >> 24);
    result[1] = (byte) ((data & 0x00FF0000) >> 16);
    result[2] = (byte) ((data & 0x0000FF00) >> 8);
    result[3] = (byte) ((data & 0x000000FF) >> 0);
    return result;        
}

It is not strange for me that none of the solutions above came up, but I saw how the igd installation removed the new version and installed the old one, for the solution I downloaded this archive:https://pypi.org/project/igd/#files

and changed the recommended version of the new version: 'lxml==4.3.0' in setup.py It works!

Pretty much anything else than PDF works, even Flash. (Tested on Safari, Firefox 3, IE 7)

Too bad.

For me it was the name of the database on application.properties. When I provided the correct name it worked ok.

you can use the following code to change color and text :

<org.jraf.android.backport.switchwidget.Switch
                        android:id="@+id/th"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        app:thumb="@drawable/apptheme_switch_inner_holo_light"
                        app:track="@drawable/apptheme_switch_track_holo_light"
                        app:textOn="@string/switch_yes"
                        app:textOff="@string/switch_no"
                        android:textColor="#000000"
                        />

Create a xml named colors.xml in res/values folder:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="red">#ff0000</color>
    <color name="green">#00ff00</color>
</resources>

In drawable folder, create a xml file my_btn_toggle.xml:

  <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_checked="false" android:drawable="@color/red"  />
        <item android:state_checked="true" android:drawable="@color/green"  />
    </selector>

and in xml section defining your toggle button add:

android:background="@drawable/my_btn_toggle

to change the color of textOn and textOffuse

android:switchTextAppearance="@style/Switch"

a quick way to see your errors whilst testing:

$error= $st->errorInfo();
echo $error[2];

For what it's worth, in ASP.NET MVC 3 you can just use User which returns the user for the current request.

Ok, that's an old question and it already have accepted answer by @siride, but that answer wasn't enough in my case, as --preserve-merges forces you to resolve all conflicts second time. My solution based on the idea by @Tobi B but with exact step-by-step commands

So we'll start on such state based on example in the question:

*   8101fe3 Merge branch 'topic'  [HEAD -> master]
|\  
| * b62cae6 2                     [topic]
| |
| | * f5a7ca8 5                   [origin/master]
| | * e7affba 4
| |/  
|/|   
* | eb3b733 3
|/  
* 38abeae 1

Note that we have 2 commits ahead master, so cherry-pick wouldn't work.

1. First of all, let's create correct history that we want:

   git checkout -b correct-history # create new branch to save master for future
   git rebase --strategy=ours --preserve-merges origin/master
   

   We use --preserve-merges to save our merge commit in history. We use --strategy=ours to ignore all merge conflicts as we don't care about what contents will be in that merge commit, we only need nice history now.

   History will looks like that (ignoring master):

   *   51984c7 Merge branch 'topic'  [HEAD -> correct-history]
   |\  
   | * b62cae6 2                     [topic]
   * | f5a7ca8 5                     [origin/master]
   * | e7affba 4
   * | eb3b733 3
   |/  
   * 38abeae 1
   

2. Let's get correct index now.

   git checkout master # return to our master branch
   git merge origin/master # merge origin/master on top of our master
   

   We may get some additional merge conflicts here, but that's would only be conflicts from files changed between 8101fe3 and f5a7ca8, but not includes already resolved conflicts from topic

   History will looks like this (ignoring correct-history):

   *   94f1484 Merge branch 'origin/master'  [HEAD -> master]
   |\  
   * | f5a7ca8 5                   [origin/master]
   * | e7affba 4
   | *   8101fe3 Merge branch 'topic'
   | |\  
   | | * b62cae6 2                     [topic]
   |/ /
   * / eb3b733 3
   |/  
   * 38abeae 1
   

3. The last stage is to combine our branch with correct history and branch with correct index

   git reset --soft correct-history
   git commit --amend
   

   We use reset --soft to reset our branch (and history) to correct-history, but leave index and working tree as is. Then we use commit --amend to rewrite our merge commit, that used to have incorrect index, with our good index from master.

   In the end we will have such state (note another id of top commit):

   *   13e6d03 Merge branch 'topic'  [HEAD -> master]
   |\  
   | * b62cae6 2                     [topic]
   * | f5a7ca8 5                     [origin/master]
   * | e7affba 4
   * | eb3b733 3
   |/  
   * 38abeae 1
   

I was not able to find the logs under Manjaro 20/Arch Linux. Instead i just stopped the docker daemon process and restarted daemon in debug mode with $ sudo dockerd -D to produce logs. It's unfortunate that the official Docker docs don't provide this info for Arch.
This should not only work for Arch, but for other systems in general.

For Intellij IDEA Community 2019.1 you will need to follow these steps :

File -> New -> Edit File Templates.. -> Class -> /* Created by ${USER} on ${DATE} */

s='foo bar baz'
a=( $s )
echo ${a[0]}
echo ${a[1]}
...

Use beforeSend:

$.ajax({
         url: "http://localhost/PlatformPortal/Buyers/Account/SignIn",
         data: { signature: authHeader },
         type: "GET",
         beforeSend: function(xhr){xhr.setRequestHeader('X-Test-Header', 'test-value');},
         success: function() { alert('Success!' + authHeader); }
      });

The best Grids in my opinion are below:

• jqGridView: http://plugins.jquery.com/project/jqGridView
• jqxGrid: http://www.jqwidgets.com/
• Ingrid: http://reconstrukt.com/ingrid/
• SlickGrid http://github.com/mleibman/SlickGrid
• DataTables http://www.datatables.net/index
• ShieldUI http://demos.shieldui.com/web/grid-virtualization/performance-1mil-rows

My best 3 options are jqGrid, jqxGrid and DataTables. They can work with thousands of rows and support virtualization.

Old post, but I just ran into a very similar problem. After some experimenting, I found that you can do this with a single command:

kill $(ps aux | grep <process_name> | grep -v "grep" | cut -d " " -f2)

In OP's case, <process_name> would be "gedit file.txt".

The most basic version responding with a JsonResult is:

// GET: api/authors
[HttpGet]
public JsonResult Get()
{
    return Json(_authorRepository.List());
}

However, this isn't going to help with your issue because you can't explicitly deal with your own response code.

The way to get control over the status results, is you need to return a ActionResult which is where you can then take advantage of the StatusCodeResult type.

for example:

// GET: api/authors/search?namelike=foo
[HttpGet("Search")]
public IActionResult Search(string namelike)
{
    var result = _authorRepository.GetByNameSubstring(namelike);
    if (!result.Any())
    {
        return NotFound(namelike);
    }
    return Ok(result);
}

Note both of these above examples came from a great guide available from Microsoft Documentation: Formatting Response Data

Extra Stuff

The issue I come across quite often is that I wanted more granular control over my WebAPI rather than just go with the defaults configuration from the "New Project" template in VS.

Let's make sure you have some of the basics down...

Step 1: Configure your Service

In order to get your ASP.NET Core WebAPI to respond with a JSON Serialized Object along full control of the status code, you should start off by making sure that you have included the AddMvc() service in your ConfigureServices method usually found in Startup.cs.

It's important to note thatAddMvc() will automatically include the Input/Output Formatter for JSON along with responding to other request types.

If your project requires full control and you want to strictly define your services, such as how your WebAPI will behave to various request types including application/json and not respond to other request types (such as a standard browser request), you can define it manually with the following code:

public void ConfigureServices(IServiceCollection services)
{
    // Build a customized MVC implementation, without using the default AddMvc(), instead use AddMvcCore().
    // https://github.com/aspnet/Mvc/blob/dev/src/Microsoft.AspNetCore.Mvc/MvcServiceCollectionExtensions.cs

    services
        .AddMvcCore(options =>
        {
            options.RequireHttpsPermanent = true; // does not affect api requests
            options.RespectBrowserAcceptHeader = true; // false by default
            //options.OutputFormatters.RemoveType<HttpNoContentOutputFormatter>();

            //remove these two below, but added so you know where to place them...
            options.OutputFormatters.Add(new YourCustomOutputFormatter()); 
            options.InputFormatters.Add(new YourCustomInputFormatter());
        })
        //.AddApiExplorer()
        //.AddAuthorization()
        .AddFormatterMappings()
        //.AddCacheTagHelper()
        //.AddDataAnnotations()
        //.AddCors()
        .AddJsonFormatters(); // JSON, or you can build your own custom one (above)
}

You will notice that I have also included a way for you to add your own custom Input/Output formatters, in the event you may want to respond to another serialization format (protobuf, thrift, etc).

The chunk of code above is mostly a duplicate of the AddMvc() method. However, we are implementing each "default" service on our own by defining each and every service instead of going with the pre-shipped one with the template. I have added the repository link in the code block, or you can check out AddMvc() from the GitHub repository..

Note that there are some guides that will try to solve this by "undoing" the defaults, rather than just not implementing it in the first place... If you factor in that we're now working with Open Source, this is redundant work, bad code and frankly an old habit that will disappear soon.

Step 2: Create a Controller

I'm going to show you a really straight-forward one just to get your question sorted.

public class FooController
{
    [HttpPost]
    public async Task<IActionResult> Create([FromBody] Object item)
    {
        if (item == null) return BadRequest();

        var newItem = new Object(); // create the object to return
        if (newItem != null) return Ok(newItem);

        else return NotFound();
    }
}

Step 3: Check your Content-Type and Accept

You need to make sure that your Content-Type and Accept headers in your request are set properly. In your case (JSON), you will want to set it up to be application/json.

If you want your WebAPI to respond as JSON as default, regardless of what the request header is specifying you can do that in a couple ways.

Way 1 As shown in the article I recommended earlier (Formatting Response Data) you could force a particular format at the Controller/Action level. I personally don't like this approach... but here it is for completeness:

Forcing a Particular Format If you would like to restrict the response formats for a specific action you can, you can apply the [Produces] filter. The [Produces] filter specifies the response formats for a specific action (or controller). Like most Filters, this can be applied at the action, controller, or global scope.

[Produces("application/json")]
public class AuthorsController

The [Produces] filter will force all actions within the AuthorsController to return JSON-formatted responses, even if other formatters were configured for the application and the client provided an Accept header requesting a different, available format.

Way 2 My preferred method is for the WebAPI to respond to all requests with the format requested. However, in the event that it doesn't accept the requested format, then fall-back to a default (ie. JSON)

First, you'll need to register that in your options (we need to rework the default behavior, as noted earlier)

options.RespectBrowserAcceptHeader = true; // false by default

Finally, by simply re-ordering the list of the formatters that were defined in the services builder, the web host will default to the formatter you position at the top of the list (ie position 0).

If we are using nodeJS, we should definitely take advantage of different libraries it provides. Inbuilt functions like each(), map(), reduce() and many more from underscoreJS reduces our efforts. Here's a sample

    var _=require("underscore");
    var fs=require("fs");

    var jsonObject=JSON.parse(fs.readFileSync('YourJson.json', 'utf8'));


    _.map( jsonObject, function(content) {
        _.map(content,function(data){
           if(data.Timestamp)
              console.log(data.Timestamp)          
           })
      })

If you have Java 7 so include the below following snippet within your app-level build.gradle :

compileOptions {

    sourceCompatibility JavaVersion.VERSION_1_7
    targetCompatibility JavaVersion.VERSION_1_7

}

I solved this by using 2 custom functions like so:

function slash_replace($query){

    return str_replace('/','_', $query);
}

function slash_unreplace($query){

    return str_replace('_','/', $query);
}

So to encode I could call:

rawurlencode(slash_replace($param))

and to decode I could call

slash_unreplace(rawurldecode($param);

Cheers!

I was able to get Font Awesome to work by using the all.min.css file.

You need to use background-image instead of backgroundImage. For example:

$(function() {
  $('.home').click(function() {
    $(this).css('background-image', 'url(images/tabs3.png)');
  });
}):

Prior to the introduction of git push -u, there was no git push option to obtain what you desire. You had to add new configuration statements.

If you create a new branch using:

$ git checkout -b branchB
$ git push origin branchB:branchB

You can use the git config command to avoid editing directly the .git/config file.

$ git config branch.branchB.remote origin
$ git config branch.branchB.merge refs/heads/branchB

Or you can edit manually the .git/config file to had tracking information to this branch.

[branch "branchB"]
    remote = origin
    merge = refs/heads/branchB

This is the most simple answer where you are not concerned about performance:

if (strpos($string, '_') === 0) {
    # code
}

If strpos returns 0 it means that what you were looking for begins at character 0, the start of the string.

It is documented thoroughly here: http://uk3.php.net/manual/en/function.strpos.php

(PS $string[0] === '_' is the best answer)

Unable to replicate. It worked fine for me:

mysql> CALL my_sqrt(4, @out_value);
Query OK, 0 rows affected (0.00 sec)

mysql> SELECT @out_value;
+------------+
| @out_value |
+------------+
| 2          | 
+------------+
1 row in set (0.00 sec)

Perhaps you should paste the entire error message instead of summarizing it.

Use this query :

SELECT 
    t.name AS table_name,
    SCHEMA_NAME(schema_id) AS schema_name,
    c.name AS column_name , *
FROM sys.tables AS t
    INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID 
Where 
    ( c.name LIKE '%' + '<ColumnName>' + '%' )
    AND 
    ( t.type = 'U' ) -- Use This To Prevent Selecting System Tables

Like this:

$result1 = mysql_query($query1);
$result2 = mysql_query($query2);

// do something with the 2 result sets...

if ($result1)
    mysql_free_result($result1);

if ($result2)
    mysql_free_result($result2);

Recently, I have seen this problem too. Below, you have my solution:

1. ping github.com, if ping failed. it is DNS error.
2. sudo vim /etc/resolv.conf, the add: nameserver 8.8.8.8 nameserver 8.8.4.4

Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart or fix it up

I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):

ssh -T [email protected]

Upon receiving a successful response, I could fetch/push to the repo with ssh.

I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.

I'd agree with some of the others out there saying that NetBeans and IntelliJ are both good IDEs. And I'd say that in using all three (Eclipse + other two), that Eclipse is by far my favorite. I found some of the documentation out-dated, but also found the support community very helpful. I started using Eclipse by jumping into the deep end of the pool: writing an RCP before ever learning the IDE. The IDE was intuitive to use, and when I found the right news groups to post to - most of my questions were already answered. The hardest thing for me (and frustrating, admittedly) was knowing how to phrase my search terms in order to get to the answer that was already posted.

Remember that Eclipse is still "relatively new" as an IDE player, though given that - it's pretty darn robust.

My only complaint about Eclipse is that with each new release, it seems to hog up more resources. With a mid-sized project/workspace, it takes seemingly forever to build (or rebuild) the project. Compared to IntelliJ, it's faster and more intuitive to use.

toCharArray followed by Arrays.sort followed by a String constructor call:

import java.util.Arrays;

public class Test
{
    public static void main(String[] args)
    {
        String original = "edcba";
        char[] chars = original.toCharArray();
        Arrays.sort(chars);
        String sorted = new String(chars);
        System.out.println(sorted);
    }
}

EDIT: As tackline points out, this will fail if the string contains surrogate pairs or indeed composite characters (accent + e as separate chars) etc. At that point it gets a lot harder... hopefully you don't need this :) In addition, this is just ordering by ordinal, without taking capitalisation, accents or anything else into account.

what error do you get is it a SmtpFailedrecipientException? if so you can check the innerexceptions list and view the StatusCode to get more information. the link below has some good information

MSDN

Edit for the new information

Thisis a problem with finding your SMTP server from what I can see, though you say that it only happens on some emails. Are you using more than one smtp server and if so maybe you can tract the issue down to one in particular, if not it may be that the speed/amount of emails you are sending is causing your smtp server some issue.

NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];  

or use

NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM 
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);

Specifically how do I tell spring-data-jpa that users that have the same username and firstname are actually EQUAL and that it is supposed to update the entity. Overriding equals did not work.

For this particular purpose one can introduce a composite key like this:

CREATE TABLE IF NOT EXISTS `test`.`user` (
  `username` VARCHAR(45) NOT NULL,
  `firstname` VARCHAR(45) NOT NULL,
  `description` VARCHAR(45) NOT NULL,
  PRIMARY KEY (`username`, `firstname`))

Mapping:

@Embeddable
public class UserKey implements Serializable {
    protected String username;
    protected String firstname;

    public UserKey() {}

    public UserKey(String username, String firstname) {
        this.username = username;
        this.firstname = firstname;
    }
    // equals, hashCode
}

Here is how to use it:

@Entity
public class UserEntity implements Serializable {
    @EmbeddedId
    private UserKey primaryKey;

    private String description;

    //...
}

JpaRepository would look like this:

public interface UserEntityRepository extends JpaRepository<UserEntity, UserKey>

Then, you could use the following idiom: accept DTO with user info, extract name and firstname and create UserKey, then create a UserEntity with this composite key and then invoke Spring Data save() which should sort everything out for you.

Try the following:

import org.openqa.selenium.support.ui.Select;

Select droplist = new Select(driver.findElement(By.Id("selection")));   
droplist.selectByVisibleText("Germany");

I have found another solution

<style type="text/css">
    .container {
        width:600px; //set how much you want
        overflow: hidden; 
        position: relative;
     }
     .containerSecond{
        position: absolute; 
        top:0px; 
        left:-500%; 
        width:1100%;
     }
     .content{
        width: 800px; //your content size 
        margin:0 auto;
     }           
</style>

and in body

<div class="container">
   <div class="containerSecond">
       <div class="content"></div>
   </div>
</div>

This will center your content div whenever your container is bigger or smaller. In this case your content should be bigger than 1100% of container to not be centered, but in that case you can make with of containerSecond bigger, and it will work

print date('Y');

For more information, check date() function documentation: https://secure.php.net/manual/en/function.date.php

<script src="foo.js?<?php echo date('YmdHis',filemtime('foo.js'));?>"></script>

It will refresh if modify.

I believe fcntl() is a POSIX function. Where as ioctl() is a standard UNIX thing. Here is a list of POSIX io. ioctl() is a very kernel/driver/OS specific thing, but i am sure what you use works on most flavors of Unix. some other ioctl() stuff might only work on certain OS or even certain revs of it's kernel.

Depending on your browser support, you could use a css animation. Browser support is IE10 and up for CSS animation. This is nice so you don't have to add jquery UI dependency if its only a small easter egg. If it is integral to your site (aka needed for IE9 and below) go with the jquery UI solution.

.your-animation {
    background-color: #fff !important;
    -webkit-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
//You have to add the vendor prefix versions for it to work in Firefox, Safari, and Opera.
@-webkit-keyframes your-animation-name {
    from { background-color: #5EB4FE;}
    to {background-color: #fff;}
}
-moz-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@-moz-keyframes your-animation-name {
    from { background-color: #5EB4FE;}
    to {background-color: #fff;}
}
-ms-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@-ms-keyframes your-animation-name {
    from { background-color: #5EB4FE;}
    to {background-color: #fff;}
}
-o-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@-o-keyframes your-animation-name {
    from { background-color: #5EB4FE;}
    to {background-color: #fff;}
}
animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@keyframes your-animation-name {
    from { background-color: #5EB4FE;}
    to {background-color: #fff;}
}

Next create a jQuery click event that adds the your-animation class to the element you wish to animate, triggering the background fading from one color to another:

$(".some-button").click(function(e){
    $(".place-to-add-class").addClass("your-animation");
});

http://wiki.answers.com/Q/Does_Google_Chrome_support_ActiveX

Google Chrome comes with an ActiveX shim, as part of its default plugin array. So Google Chrome features at least partial support for ActiveX controls (as do many non-Internet Explorer browsers). I can't find information as to whether or not this includes support for ActiveX security certificates or the like, nor if/where such plugins can be controlled, within the browser.

..... Note that to enable the plug-in you must run Chrome with the following switch " --allow-all-activex" So in shortcut that is used to start up Chrome, add this after "Chrome.exe"

Thought I'd add an answer since your question title looks like it is asking how to create or update, rather than get or create as described in the question body.

If you did want to create or update an object, the .save() method already has this behaviour by default, from the docs:

Django abstracts the need to use INSERT or UPDATE SQL statements. Specifically, when you call save(), Django follows this algorithm:

If the object’s primary key attribute is set to a value that evaluates to True (i.e., a value other than None or the empty string), Django executes an UPDATE. If the object’s primary key attribute is not set or if the UPDATE didn’t update anything, Django executes an INSERT.

It's worth noting that when they say 'if the UPDATE didn't update anything' they are essentially referring to the case where the id you gave the object doesn't already exist in the database.

How about writing a custom attribute:

public class LocalizedDisplayNameAttribute: DisplayNameAttribute
{
    public LocalizedDisplayNameAttribute(string resourceId) 
        : base(GetMessageFromResource(resourceId))
    { }

    private static string GetMessageFromResource(string resourceId)
    {
        // TODO: Return the string from the resource file
    }
}

which could be used like this:

public class MyModel 
{
    [Required]
    [LocalizedDisplayName("labelForName")]
    public string Name { get; set; }
}

Here's a better approach where you don't have to delete/move anything for Android Studio 3.+.

1. Open Android Studio and click cancel/ignore for error prompts on missing SDK for each project.
2. Close all your open projects. You can do this by File > Close Project.
3. After you do step 1 for all projects, the Welcome screen appears.
4. The welcome screen will detect you are missing the SDK and give you options to fix the problem, i.e., install the SDKs for you.

Python's standard library has json and urllib2 modules.

import json
import urllib2

data = json.load(urllib2.urlopen('http://someurl/path/to/json'))

It is an extremely overused way to check for the success/failure of a command. Typically, the code snippet you give would be refactored as:

if grep -e ERROR ${LOG_DIR_PATH}/${LOG_NAME} > /dev/null; then
   ...
fi

(Although you can use 'grep -q' in some instances instead of redirecting to /dev/null, doing so is not portable. Many implementations of grep do not support the -q option, so your script may fail if you use it.)

Don't forget that If you constraint some view's bottom to constraint layout's bottom.Scrollview could not scroll.

Quite logical the difference between PUT & PATCH w.r.t sending full & partial data for replacing/updating respectively. However, just couple of points as below

1. Sometimes POST is considered as for updates w.r.t PUT for create
2. Does HTTP mandates/checks for sending full vs partial data in PATCH? Otherwise, PATCH may be quite same as update as in PUT/POST

The distribute package provides a Python 3-compatible version of setuptools: http://pypi.python.org/pypi/distribute

Also, use pip to install the modules. It automatically finds dependencies and installs them for you.

It works just fine for me with your package:

[~] pip --version                                                              
pip 1.2.1 from /usr/lib/python3.3/site-packages (python 3.3)
[~] sudo pip install ansicolors                                                
Downloading/unpacking ansicolors
  Downloading ansicolors-1.0.2.tar.gz
  Running setup.py egg_info for package ansicolors

Installing collected packages: ansicolors
  Running setup.py install for ansicolors

I had similar issue, but in the end I found out that ~/.bashrc was all I needed.

However, in Ubuntu, I had to comment the line that stops processing ~/.bashrc :

#If not running interactively, don't do anything
[ -z "$PS1" ] && return

As stated in other answers before; while this cannot be expressed in source-code it can actually be done on IL Level. @Christopher Currens answer shows how the IL do to that.

With Fodys Add-In ExtraConstraints.Fody there's a very simple way, complete with build-tooling, to achieve this. Just add their nuget packages (Fody, ExtraConstraints.Fody) to your project and add the constraints as follows (Excerpt from the Readme of ExtraConstraints):

public void MethodWithEnumConstraint<[EnumConstraint] T>() {...}

public void MethodWithTypeEnumConstraint<[EnumConstraint(typeof(ConsoleColor))] T>() {...}

and Fody will add the necessary IL for the constraint to be present. Also note the additional feature of constraining delegates:

public void MethodWithDelegateConstraint<[DelegateConstraint] T> ()
{...}

public void MethodWithTypeDelegateConstraint<[DelegateConstraint(typeof(Func<int>))] T> ()
{...}

Regarding Enums, you might also want to take note of the highly interesting Enums.NET.

As my background and main environment is C, I will provide some statements/citations to that topic from the actual C standard and an important reference book, from also one of the developers of C, which is often cited and common treated as the first unofficial standard of C:

The C Programming Language (2nd Edition) by Brian W. Kernighan and Dennis M. Ritchie (April 1988):

Page 25, Section 1.7 - Functions

We will generally use parameter for a variable named in the parenthesized list in a function definition, and argument for the value used in the call of the function. The terms formal argument and actual argument are sometimes used for the same distinction.

ISO/IEC 9899:2018 (C18):

3.3

argument

actual argument

DEPRECATED: actual parameter

expression in the comma-separated list bounded by the parentheses in a function call expression, or a sequence of preprocessing tokens in the comma-separated list bounded by the parentheses in a function-like macro invocation.

3.16

parameter

formal parameter

DEPRECATED: formal argument

object declared as part of a function declaration or definition that acquires a value on entry to the function, or an identifier from the comma-separated list bounded by the parentheses immediately following the macro name in a function-like macro definition.

For above v4

$('#yourselect').on("select2:select", function(e) { 
     // after selection of select2 
});

Here is the exact solution, which worked in my case:

1. On IE 7 or higher on Windows Vista or Windows 7, you must set the Protected Mode settings for each zone to be the same value. The value can be on or off, as long as it is the same for every zone. To set the Protected Mode settings, choose "Internet Options..." from the Tools menu, and click on the Security tab. For each zone, there will be a check box at the bottom of the tab labeled "Enable Protected Mode". Additionally, "Enhanced Protected Mode" must be disabled for IE 10 and higher. This option is found in the Advanced tab of the Internet Options dialog.

2. System.setProperty("webdriver.ie.driver","C:\\Users\\ssin22\\Downloads\\IEDriverServer_x64_2.48.0\\IEDriverServer.exe");

package Testing;

import java.io.File;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;

public class LaunchIE {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        System.setProperty("webdriver.ie.driver","C:\\Users\\ssin22\\Downloads\\IEDriverServer_x64_2.48.0\\IEDriverServer.exe");

    WebDriver driver=new InternetExplorerDriver();
    driver.get("http://google.com");

    }

}

You can also do this with positioning, set parent div to relative and child div to absolute.

.wrapper {
      position: relative;
  }
.childDiv {
      position: absolute;
      left: 50%;
      transform: translateX(-50%);
  }

To get the native reference to something like an ion-input, ry using this

@ViewChild('fileInput', { read: ElementRef }) fileInput: ElementRef;

and then

this.fileInput.nativeElement.querySelector('input').click()

I created a directive for this (angular stable 1.0.8)

<input type="text" input-disabled="editableInput" />
<button ng-click="editableInput = !editableInput">enable/disable</button>

app.controller("myController", function(){
  $scope.editableInput = false;
});

app.directive("inputDisabled", function(){
  return function(scope, element, attrs){
    scope.$watch(attrs.inputDisabled, function(val){
      if(val)
        element.removeAttr("disabled");
      else
        element.attr("disabled", "disabled");
    });
  }
});

There are multiple approaches you can choose from:

1. Approach: FileReader

Load the image as blob via XMLHttpRequest and use the FileReader API (readAsDataURL()) to convert it to a dataURL:

function toDataURL(url, callback) {
  var xhr = new XMLHttpRequest();
  xhr.onload = function() {
    var reader = new FileReader();
    reader.onloadend = function() {
      callback(reader.result);
    }
    reader.readAsDataURL(xhr.response);
  };
  xhr.open('GET', url);
  xhr.responseType = 'blob';
  xhr.send();
}

toDataURL('https://www.gravatar.com/avatar/d50c83cc0c6523b4d3f6085295c953e0', function(dataUrl) {
  console.log('RESULT:', dataUrl)
})

This code example could also be implemented using the WHATWG fetch API:

const toDataURL = url => fetch(url)
  .then(response => response.blob())
  .then(blob => new Promise((resolve, reject) => {
    const reader = new FileReader()
    reader.onloadend = () => resolve(reader.result)
    reader.onerror = reject
    reader.readAsDataURL(blob)
  }))


toDataURL('https://www.gravatar.com/avatar/d50c83cc0c6523b4d3f6085295c953e0')
  .then(dataUrl => {
    console.log('RESULT:', dataUrl)
  })

These approaches:

• lack in browser support

• have better compression
• work for other file types as well

• http://caniuse.com/#feat=fetch

2. Approach: Canvas

Load the image into an Image-Object, paint it to a nontainted canvas and convert the canvas back to a dataURL.

function toDataURL(src, callback, outputFormat) {
  var img = new Image();
  img.crossOrigin = 'Anonymous';
  img.onload = function() {
    var canvas = document.createElement('CANVAS');
    var ctx = canvas.getContext('2d');
    var dataURL;
    canvas.height = this.naturalHeight;
    canvas.width = this.naturalWidth;
    ctx.drawImage(this, 0, 0);
    dataURL = canvas.toDataURL(outputFormat);
    callback(dataURL);
  };
  img.src = src;
  if (img.complete || img.complete === undefined) {
    img.src = "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw==";
    img.src = src;
  }
}

toDataURL(
  'https://www.gravatar.com/avatar/d50c83cc0c6523b4d3f6085295c953e0',
  function(dataUrl) {
    console.log('RESULT:', dataUrl)
  }
)

In detail

Supported input formats:

image/png, image/jpeg, image/jpg, image/gif, image/bmp, image/tiff, image/x-icon, image/svg+xml, image/webp, image/xxx

Supported output formats:

image/png, image/jpeg, image/webp(chrome)

Browser Support:

• http://caniuse.com/#feat=canvas

• Internet Explorer 10 (Internet Explorer 10 just works with same origin images)

3. Approach: Images from the local file system

If you want to convert images from the users file system you need to take a different approach. Use the FileReader API:

function encodeImageFileAsURL(element) {
  var file = element.files[0];
  var reader = new FileReader();
  reader.onloadend = function() {
    console.log('RESULT', reader.result)
  }
  reader.readAsDataURL(file);
}

<input type="file" onchange="encodeImageFileAsURL(this)" />

You have a couple of basic misconceptions about Java:

I want it to return the array without having to explicitly tell the console to print.

1) Java does not work that way. Nothing ever gets printed implicitly. (Java does not support an interactive interpreter with a "repl" loop ... like Python, Ruby, etc.)

2) The "main" doesn't "return" anything. The method signature is:

  public static void main(String[] args)

and the void means "no value is returned". (And, sorry, no you can't replace the void with something else. If you do then the java command won't recognize the "main" method.)

3) If (hypothetically) you did want your "main" method to return something, and you altered the declaration to allow that, then you still would need to use a return statement to tell it what value to return. Unlike some language, Java does not treat the value of the last statement of a method as the return value for the method. You have to use a return statement ...

For me path for templateUrl was not correct

I was using

shopping-list-edit.component.html

Whereas it should have been

./shopping-list-edit.component.html

Silly mistake but happens when starting out. Hope that helps somebody in distress.

I removed your document.getElementById("Save").onclick = before your functions, because it's an event already being called on your button. I also had to call the two functions separately by the onclick event.

     <!DOCTYPE html>
      <html>
      <head>
      <script>
       function fun()
        {
         alert("hello");
         //validation code to see State field is mandatory.  
        }   
        function f1()
        {
          alert("f1 called");
           //form validation that recalls the page showing with supplied inputs.    
        }
      </script>
      </head>
      <body>
      <form name="form1" id="form1" method="post">
                State: 
                <select id="state ID">
                   <option></option>
                   <option value="ap">ap</option>
                   <option value="bp">bp</option>
                </select>
       </form>

       <table><tr><td id="Save" onclick="f1(); fun();">click</td></tr></table>

   </body>
   </html>

You either have to write your own sort by hand, or maybe try this technique:

http://www.aspfaqs.com/aspfaqs/ShowFAQ.asp?FAQID=83

You can freely intermix server side javascript with VBScript, so wherever VBScript falls short, switch to javascript.

Use this one:

Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")

Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")

With rng.Validation
    .Delete 'delete previous validation
    .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
        Formula1:="='" & ws.Name & "'!" & range1.Address
End With

Note that when you're using Dim range1, rng As range, only rng has type of Range, but range1 is Variant. That's why I'm using Dim range1 As Range, rng As Range.
About meaning of parameters you can read is MSDN, but in short:

• Type:=xlValidateList means validation type, in that case you should select value from list
• AlertStyle:=xlValidAlertStop specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.
• in your original code, Operator:= xlBetween is odd. It can be used only if two formulas are provided for validation.
• Formula1:="='" & ws.Name & "'!" & range1.Address for list data validation provides address of list with values (in format =Sheet!A1:A5)

Leaving an incredibly simple example in case it helps.

When variable doesn't exist:

if defined? a then "hi" end
# => nil

When variable does exist:

a = 2
if defined? a then "hi" end
# => "hi"

Your confusion stems from the fact that declared properties are not (necessarily named the same as) (instance) variables.

The expresion

indexPath.row

is equivalent to

[indexPath row]

and the assignment

delegate.myData = [myData objectAtIndex:indexPath.row];

is equivalent to

[delegate setMyData:[myData objectAtIndex:[indexPath row]]];

assuming standard naming for synthesised properties.

Furthermore, delegate is probably declared as being of type id<SomeProtocol>, i.e., the compiler hasn’t been able to provide actual type information for delegate at that point, and the debugger is relying on information provided at compile-time. Since id is a generic type, there’s no compile-time information about the instance variables in delegate.

Those are the reasons why you don’t see myData or row as variables.

If you want to inspect the result of sending -row or -myData, you can use commands p or po:

p (NSInteger)[indexPath row]
po [delegate myData]

or use the expressions window (for instance, if you know your delegate is of actual type MyClass *, you can add an expression (MyClass *)delegate, or right-click delegate, choose View Value as… and type the actual type of delegate (e.g. MyClass *).

That being said, I agree that the debugger could be more helpful:

• There could be an option to tell the debugger window to use run-time type information instead of compile-time information. It'd slow down the debugger, granted, but would provide useful information;

• Declared properties could be shown up in a group called properties and allow for (optional) inspection directly in the debugger window. This would also slow down the debugger because of the need to send a message/execute a method in order to get information, but would provide useful information, too.

For small scripts an optional way to make it readable is to use a variable like this:

awk -v fmt="'%s'\n" '{printf fmt, $1}'

I found it conveninet in a case where I had to produce many times the single-quote character in the output and the \047 were making it totally unreadable

String interpolation is a nice way to pass in a formatted string.

values = ', '.join('$%s' % v for v in value_list)

Instead of using np.argsort you could use np.argpartition - if you only need the indices of the lowest/highest n elements.

That doesn't require to sort the whole array but just the part that you need but note that the "order inside your partition" is undefined, so while it gives the correct indices they might not be correctly ordered:

>>> avgDists = [1, 8, 6, 9, 4]
>>> np.array(avgDists).argpartition(2)[:2]  # indices of lowest 2 items
array([0, 4], dtype=int64)

>>> np.array(avgDists).argpartition(-2)[-2:]  # indices of highest 2 items
array([1, 3], dtype=int64)

Your solution is fine but you can use an iterator to do it:

std::map<int, int> m;
m.insert(std::pair<int, int>(3, 4));
m.insert(std::pair<int, int>(5, 6));
for(std::map<int, int>::const_iterator it = m.begin(); it != m.end(); it++)
{
    int key = it->first;
    int value = it->second;
    //Do something
}

In Excel 2013 simply select multiple sheets and do a "Save As" and select PDF as the file type. The multiple pages will open in PDF when you click save.

For the above issue, first of all if suppose tables contains more than 1 primary key then first remove all those primary keys and add first AUTO INCREMENT field as primary key then add another required primary keys which is removed earlier. Set AUTO INCREMENT option for required field from the option area.

In my opinion, it is not possible for the like button (and I hope it is not possible).

But, you can trigger a custom OpenGraph v2 action, or display a like button linked to your facebook page.

Like vikingosgundo said, but keep in mind that if you use [UIImage imageNamed:image] then the image is cached and eats away memory. So unless you plan on using the same image in many places, you should load the image, with imageWithContentsOfFile: and imageWithData:

This will save you significant memory and speeds up your app.

For Xamarin.iOS inside AppDelegate's FinishedLaunching() put code like this :-

UILabel.Appearance.Font= UIFont.FromName("Lato-Regular", 14);

set font for the entire application and Add 'UIAppFonts' key on Info.plist , the path should be the path where your font file .ttf is situated .For me it was inside 'fonts' folder in my project.

<key>UIAppFonts</key>
    <array>
        <string>fonts/Lato-Regular.ttf</string>
    </array>

If you don't have the token at the time of the call is made, You will have to make two calls, one to get the token and the other to extract the token form the response, pay attention to

grep token | cut -d, -f1 | cut -d\" -f4

as it is the part which is dealing with extracting the token from the response.

echo "Getting token response and extracting token"    
def token = sh (returnStdout: true, script: """
    curl -S -i -k -X POST https://www.example.com/getToken -H \"Content-Type: application/json\" -H \"Accept: application/json\" -d @requestFile.json | grep token | cut -d, -f1 | cut -d\\" -f4
""").split()

After extracting the token you can use the token to make subsequent calls as follows.

echo "Token : ${token[-1]}"       
echo "Making calls using token..."       
curl -S -i -k  -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer ${token[-1]}" https://www.example.com/api/resources 

To quote the bash man page:

There is no mechanism for using arguments in the replacement text. If arguments are needed, a shell function should be used (see FUNCTIONS below).

So it looks like you've answered your own question -- use a function instead of an alias

There are several ways to do a cross join or cartesian product:

SELECT column_names FROM table1 CROSS JOIN table2;

SELECT column_names FROM table1, table2;

SELECT column_names FROM table1 JOIN table2;

Neglecting the on condition in the third case is what results in a cross join.

Are you referring to the server side or the client side?

For a client, you would want to adjust the sendTimeout attribute of a binding element. For a service, you would want to adjust the receiveTimeout attribute of a binding elemnent.

<system.serviceModel>
  <bindings>
    <netTcpBinding>
      <binding name="longTimeoutBinding"
        receiveTimeout="00:10:00" sendTimeout="00:10:00">
        <security mode="None"/>
      </binding>
    </netTcpBinding>
  </bindings>

  <services>
    <service name="longTimeoutService"
      behaviorConfiguration="longTimeoutBehavior">
      <endpoint address="net.tcp://localhost/longtimeout/"
        binding="netTcpBinding" bindingConfiguration="longTimeoutBinding" />
    </service>
....

Of course, you have to map your desired endpoint to that particular binding.

To avoid the TOCTOU issue highlighted by Éric Araujo's comment, you can catch an exception to call the correct method:

def remove_file_or_dir(path: str) -> None:
    """ Remove a file or directory """
    try:
        shutil.rmtree(path)
    except NotADirectoryError:
        os.remove(path)

Since shutil.rmtree() will only remove directories and os.remove() or os.unlink() will only remove files.

I found that none of the answers here applied to my specific use case, so I thought I would share my solution.

I was looking to redirect an unauthentciated user to public version of an app page with any possible URL params. Example:

/app/4903294/my-great-car?email=coolguy%40gmail.com to

/public/4903294/my-great-car?email=coolguy%40gmail.com

Here's the solution that worked for me.

return redirect(url_for('app.vehicle', vid=vid, year_make_model=year_make_model, **request.args))

Hope this helps someone!

When I had this problem I fixed it by turning off the 'Enable ClickOnce security settings'.

Menu: Project | 'Project name' Properties... | Security tab | 'Enable ClickOnce security settings' check box.

With serialize the data as JSON and Base64, dependency jquery.cookie.js :

var putCookieObj = function(key, value) {
    $.cookie(key, btoa(JSON.stringify(value)));
}

var getCookieObj = function (key) {
    var cookie = $.cookie(key);
    if (typeof cookie === "undefined") return null;
    return JSON.parse(atob(cookie));
}

:)

iris %>% dplyr::select(where(is.numeric)) #as per most recent updates

Another option with purrr would be to negate discard function:

iris %>% purrr::discard(~!is.numeric(.))

If you want the names of the numeric columns, you can add names or colnames:

iris %>% purrr::discard(~!is.numeric(.)) %>% names

Emoji support for application having tech stack - mysql, java, springboot, hibernate

Apply below changes in mysql for unicode support.

1. ALTER DATABASE <database-name> CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;
2. ALTER TABLE <table-name> CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

DB Connection - jdbc url change:

jdbc:mysql://localhost:3306/<database-name>?useUnicode=yes&characterEncoding=UTF-8

Note - If the above step is not working please update mysql-connector version to 8.0.15. (mysql 5.7 works with connector version 8.0.15 for unicode support)

I came across this thread and solve the issue by below steps, My problem may be different. Hope this can help some one .

In nutshell: CANDIDATE KEY is a minimal SUPER KEY.

Where Super key is the combination of columns(or attributes) that uniquely identify any record(or tuple) in a relation(table) in RDBMS.

For instance, consider the following dependencies in a table having columns A, B, C, and D (Giving this table just for a quick example so not covering all dependencies that R could have).

Attribute set (Determinant)---Can Identify--->(Dependent)

A-----> AD

B-----> ABCD

C-----> CD

AC----->ACD

AB----->ABCD

ABC----->ABCD

BCD----->ABCD

Now, B, AB, ABC, BCD identifies all columns so those four qualify for the super key.

But, B?AB; B?ABC; B?BCD hence AB, ABC, and BCD disqualified for CANDIDATE KEY as their subsets could identify the relation, so they aren't minimal and hence only B is the candidate key, not the others.

One more thing Primary key is any one among the candidate keys.

Thanks for asking

I don't know if this will help but I was getting the same error when remote debugging a react-native application. I was running the debugger on 192.168.x.x:8081. I read a little bit on this Cross-Origin Resource Sharing (CORS) to educate myself on what CORS is. (I'm a beginner) and changed my URL from IP:8081 to localhost:8081 and my issue was resolved.

You can put the property with null as a default value and if you don't pass the parameter it will not be interpreted.

@mixin box-shadow($top, $left, $blur, $color, $inset:null) {
  -webkit-box-shadow: $top $left $blur $color $inset;
  -moz-box-shadow:    $top $left $blur $color $inset;
  box-shadow:         $top $left $blur $color $inset;
}

This means you can write the include statement like this.

@include box-shadow($top, $left, $blur, $color);

Instead of writing it like this.

@include box-shadow($top, $left, $blur, $color, null);

As shown in the answer here

If you merged the branch, then reverted the merge using a pull request and merged that pull request to revert.

The easiest way I felt was to:

1. Take out a new branch from develop/master (where you merged)
2. Revert the "revert" using git revert -m 1 xxxxxx (if the revert was merged using a branch) or using git revert xxxxxx if it was a simple revert
3. The new branch should now have the changes you want to merge again.
4. Make changes or merge this branch to develop/master

$UTC_Time   = "2018-07-06 06:06:16";
echo "UTC Time ".$UTC_Time;
$Indian_Time = TimeConverion($UTC_Time);
echo "<br> Indian_Time ".$Indian_Time;

function TimeConverion($UTC_Time) {
  date_default_timezone_set('Europe/London');
  $sTime = date("Y-m-d h:i:sa");
  $ts3 = strtotime(date("G:i:s"))-strtotime($sTime); 
  $utc = explode(" ",$UTC_Time);
  $time = strtotime($utc[1]);
  date_default_timezone_set("Asia/Calcutta");
  $time += $ts3;  // Add the difference
  return $utc[0]." ".date("H:i:s", $time);
}

Or you can: hadoop fs -rm -r PATH

Hint: if you enter: hadoop fs -rmr PATH you would mostly get:Please use 'rm -r' instead.

simplifying:

a = 10; b = 15; c = 20

public static boolean check(int a, int b, int c) {
    return a<=b && b<=c;
}

This checks if b is between a and c

Or you can simply update without using join like this:

Update t1 set  t1.Description = t2.Description from @tbl2 t2,tbl1 t1
where t1.ID= t2.ID

You can't access element like you did (document.frm_new_user_request). You have to use the function getElementById:

document.getElementById("frm_new_user_request")

So getting a value from an input could look like this:

var value = document.getElementById("frm_new_user_request").value

Also you can use some JavaScript framework, e.g. jQuery, which simplifies operations with DOM (Document Object Model) and also hides differences between various browsers from you.

Getting a value from an input using jQuery would look like this:

• input with ID "element": var value = $("#element).value
• input with class "element": var value = $(".element).value

I know this is an old question, but I had a similar issue and found that:

lm(x ~ y + relevel(b, ref = "3")) 

does exactly what you asked.

I think this may answer your question.

Non-static method ..... should not be called statically

If the method is not static you need to initialize it like so:

$var = new ClassName();
$var->method();

Or, in PHP 5.4+, you can use this syntax:

(new ClassName)->method();

In general it makes sense only to display the Whatsapp Link on iOS or Android Devices only, using java script:

   if (navigator.userAgent.match(/iPhone|Android/i)) {
      document.write('<a href="whatsapp://send?text=See..">Share on WhatApp</a>');
   }

In my sample code, I was setting my object to nothing, and I couldn't get the "not" part of the if statement to work with the object. I tried if My_Object is not nothing and also if not My_Object is nothing. It may be just a syntax thing I can't figure out but I didn't have time to mess around, so I did a little workaround like this:

if My_Object is Nothing Then
    'do nothing
Else
    'Do something
End if

I am getting day, month and year using dedicated functions moment().date(), moment().month() and moment().year() of momentjs.

let day = moment('2014-07-28', 'YYYY/MM/DD').date();_x000D_
let month = 1 + moment('2014-07-28', 'YYYY/MM/DD').month();_x000D_
let year = moment('2014-07-28', 'YYYY/MM/DD').year();_x000D_
_x000D_
console.log(day);_x000D_
console.log(month);_x000D_
console.log(year);

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.1/moment.min.js"></script>

I don't know why there are 48 upvotes for @Chris Schmitz answer which is not 100% correct.

Month is in form of array and starts from 0 so to get exact value we should use 1 + moment().month()

Another Possible solution is to reinstall typings:
This works for me for "angular2": "2.0.0-beta.15"

1. npm clean cache
2. npm install
3. npm install -g typings
4. Delete typings directory from project (Directory wwhere typings modules are installed)
5. typings install
6. npm run

I guess you will get ORA-01741: illegal zero-length identifier if you use the following

SELECT "" AS Contact  FROM Customers;

And if you use the following 2 statements, you will be getting the same null value populated in the column.

SELECT '' AS Contact FROM Customers; OR SELECT null AS Contact FROM Customers;

Go to "https://nodejs.org/en/" and then download either the latest or most stable versions. After downloading, Mac pkg installer updated the existing version. In linux: apt and windows installer will take care.

When I did the npm -v from cmd it gave the most stable version which I have downloaded and installed from the above link.

xyz-MacBook-Pro:~ aasdfa$ node -v v8.11.1

Try this:

<form method="post" action="check.php">
    <select name="website_string">
        <option value="" selected="selected"></option>
        <option VALUE="abc"> ABC</option>
        <option VALUE="def"> def</option>
        <option VALUE="hij"> hij</option>
    </select>
    <input TYPE="submit" name="submit" />
</form>

Both your select control and your submit button had the same name attribute, so the last one used was the submit button when you clicked it. All other syntax errors aside.

check.php

<?php
    echo $_POST['website_string'];
?>

Obligatory disclaimer about using raw $_POST data. Sanitize anything you'll actually be using in application logic.

Escape dot. Sample command will be.

grep '0\.00'

I did it with jQuery:

page.execute_script %Q{ $('#some_id').prop('checked', true) }

I know this is an old post but I thought I could share an alternative [not as robust, but simpler] approach to searching for a string in a table.

$("tr:contains(needle)"); //where needle is the text you are searching for.

For example, if you are searching for the text 'box', that would be:

$("tr:contains('box')");

This would return all the elements with this text. Additional criteria could be used to narrow it down if it returns multiple elements

There are two approaches which are not mentioned above, but both of which solve the problem in a way which complies with PEP 8 and allow you to make better use of your space. They are:

msg = (
    'This message is so long, that it requires '
    'more than {x} lines.{sep}'
    'and you may want to add more.').format(
        x=x, sep=2*'\n')
print(msg)

Notice how the parentheses are used to allow us not to add plus signs between pure strings, and spread the result over multiple lines without the need for explicit line continuation '\' (ugly and cluttered). The advantages are same with what is described below, the difference is that you can do it anywhere. Compared to the previous alternative, it is visually better when inspecting code, because it outlines the start and end of msg clearly (compare with msg += one every line, which needs one additional thinking step to deduce that those lines add to the same string - and what if you make a typo, forgetting a + on one random line ?).

Regarding this approach, many times we have to build a string using iterations and checks within the iteration body, so adding its pieces within the function call, as shown later, is not an option.

A close alternative is:

msg = 'This message is so long, that it requires '
msg += 'many lines to write, one reason for that\n'
msg += 'is that it contains numbers, like this '
msg += 'one: ' + str(x) +', which take up more space\n'
msg += 'to insert. Note how newlines are also included '
msg += 'and can be better presented in the code itself.'
print(msg)

Though the first is preferable.

The other approach is like the previous ones, though it starts the message on the line below the print. The reason for this is to gain space on the left, otherwise the print( itself "pushes" you to the right. This consumption of indentation is the inherited by the rest of the lines comprising the message, because according to PEP 8 they must align with the opening parenthesis of print above them. So if your message was already long, this way it's forced to be spread over even more lines.

Contrast:

raise TypeError('aaaaaaaaaaaaaaaa' +
                'aaaaaaaaaaaaaaaa' +
                'aaaaaaaaaaaaaaaa')

with this (suggested here):

raise TypeError(
    'aaaaaaaaaaaaaaaaaaaaaaaa' +
    'aaaaaaaaaaaaaaaaaaaaaaaa')

The line spread was reduced. Of course this last approach does no apply so much to print, because it is a short call. But it does apply to exceptions.

A variation you can have is:

raise TypeError((
    'aaaaaaaaaaaaaaaaaaaaaaaa'
    'aaaaaaaaaaaaaaaaaaaaaaaa'
    'aaaaa {x} aaaaa').format(x=x))

Notice how you don't need to have plus signs between pure strings. Also, the indentation guides the reader's eyes, no stray parentheses hanging below to the left. The replacements are very readable. In particular, such an approach makes writing code that generates code or mathematical formulas a very pleasant task.

<input type="text" class="form-control timepicker2" ng-model='programRow.StationAuxiliaryTime.ST88' />

accessing scope value

assume that programRow.StationAuxiliaryTime is an array of object

 $('.timepicker2').on('click', function () 
    {
            var currentElement = $(this);

            var scopeValues = angular.element(currentElement).scope();
            var model = currentElement.attr('ng-model');
            var stationNumber = model.split('.')[2];
            var val = '';
            if (model.indexOf("StationWaterTime") > 0) {
                val = scopeValues.programRow.StationWaterTime[stationNumber];
            }
            else {
                val = scopeValues.programRow.StationAuxiliaryTime[stationNumber];
            }
            currentElement.timepicker('setTime', val);
        });

I have added below configuration to the httpd.conf and restarted the lampp service and it started working. Thanks to all the above posts, which helped me to resolve issues one by one.

Listen 8080
<VirtualHost *:8080>

    DocumentRoot "/opt/lampp/docs/dummy-host2.example.com"
    ServerName localhost:8080

The best way to do this would be to use the promise returning function as it is, like this

lookupValue(file).then(function(res) {
    // Write the code which depends on the `res.val`, here
});

The function which invokes an asynchronous function cannot wait till the async function returns a value. Because, it just invokes the async function and executes the rest of the code in it. So, when an async function returns a value, it will not be received by the same function which invoked it.

So, the general idea is to write the code which depends on the return value of an async function, in the async function itself.

You can also set DirectoryIndex in apache's httpd.conf file.

CentOS keeps this file in /etc/httpd/conf/httpd.conf Debian: /etc/apache2/apache2.conf

Open the file in your text editor and find the line starting with DirectoryIndex

To load landing.html as a default (but index.html if that's not found) change this line to read:

DirectoryIndex  landing.html index.html

You need to change from queue import Queue to from multiprocessing import Queue.

The root reason is the former Queue is designed for threading module Queue while the latter is for multiprocessing.Process module.

For details, you can read some source code or contact me!

You may find it more readable to reverse your logic and use an else statement with an empty if.

if($some_variable === 'uk' || $another_variable === 'in'){}

else {
    // This occurs when neither of the above are true
}

The discoverability is dismal, but it's quite clever how Advanced Rest Client handles basic authentication. The shortcut abraham mentioned didn't work for me, but a little poking around revealed how it does it.

The first thing you need to do is add the Authorization header:

Then, a nifty little thing pops up when you focus the value input (note the "construct" box in the lower right):

Clicking it will bring up a box. It even does OAuth, if you want!

Tada! If you leave the value field blank when you click "construct," it will add the Basic part to it (I assume it will also add the necessary OAuth stuff, too, but I didn't try that, as my current needs were for basic authentication), so you don't need to do anything.

What you could do is add the text as value, which respects the line break \n.

$('textarea').attr('value', 'This is a line \nthis should be a new line');

Then you could remove it on focus and apply it back (if empty) on blur. Something like this

var placeholder = 'This is a line \nthis should be a new line';
$('textarea').attr('value', placeholder);

$('textarea').focus(function(){
    if($(this).val() === placeholder){
        $(this).attr('value', '');
    }
});

$('textarea').blur(function(){
    if($(this).val() ===''){
        $(this).attr('value', placeholder);
    }    
});

Not pure CSS and not clean but does the trick.

Alright, so there are obviously not a whole lot of people who have tried the .NET 4 menu as of today. Not surprising as the final version was released a couple days ago. I seem to be the first one to ever report on what seems to be a bug. I will report this to MS if I find the time, but given MS track-record of not paying attention to bug reports I'm not rushing this.

Anyway, at this point the least worst solution is to copy and paste the CSS styles generated by the control (check the header) into your own stylesheet and modify it from there. After you're done doing this, don't forget to set IncludeStyleBlock="False" on your menu so as to prevent the automatic generation of the CSS, since we'll be using the copied block from now on. Conceptually this is not correct as your application shouldn't rely on automatically generated code, but that's the only option I can think of.

Towards the second half of Create REST API using ASP.NET MVC that speaks both JSON and plain XML, to quote:

Now we need to accept JSON and XML payload, delivered via HTTP POST. Sometimes your client might want to upload a collection of objects in one shot for batch processing. So, they can upload objects using either JSON or XML format. There's no native support in ASP.NET MVC to automatically parse posted JSON or XML and automatically map to Action parameters. So, I wrote a filter that does it."

He then implements an action filter that maps the JSON to C# objects with code shown.
