Take a look here: http://longgoldenears.blogspot.com/2007/09/triple-equals-in-javascript.html

The 3 equal signs mean "equality without type coercion". Using the triple equals, the values must be equal in type as well.

0 == false   // true
0 === false  // false, because they are of a different type
1 == "1"     // true, automatic type conversion for value only
1 === "1"    // false, because they are of a different type
null == undefined // true
null === undefined // false
'0' == false // true
'0' === false // false

I will explain with simple example

1. [1,3,2] <=> [2,2,2]

   Ruby will start comparing each element of both array from left hand side. 1 for left array is smaller than 2 of right array. Hence left array is smaller than right array. Output will be -1.

2. [2,3,2] <=> [2,2,2]

   As above it will first compare first element which are equal then it will compare second element, in this case second element of left array is greater hence output is 1.

I assume that the main idea is to find if number is negative and display it in correct format.

For those who use PHP5.3 might be interested in using Number Formatter Class - http://php.net/manual/en/class.numberformatter.php. This function, as well as range of other useful things, can format your number.

$profitLoss = 25000 - 55000;

$a= new \NumberFormatter("en-UK", \NumberFormatter::CURRENCY); 
$a->formatCurrency($profitLoss, 'EUR');
// would display (€30,000.00)

Here also a reference to why brackets are used for negative numbers: http://www.open.edu/openlearn/money-management/introduction-bookkeeping-and-accounting/content-section-1.7

By default structs do not have a == operator. You'll have to write your own implementation:

bool MyStruct1::operator==(const MyStruct1 &other) const {
    ...  // Compare the values, and return a bool result.
  }

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

If you just use

not var1 

it is not possible to difference a variable which is boolean False from an empty string '':

var1 = ''
not var1
> True

var1 = False
not var1
> True

However, if you add a simple condition to your script, the difference is made:

var1  = False
not var1 and var1 != ''
> True

var1 = ''
not var1 and var1 != ''
> False

An article on Testing Private Methods lays out some approaches to testing private code. using reflection puts extra burden on the programmer to remember if refactoring is done, the strings aren't automatically changed, but I think it's the cleanest approach.

Just put the full directory location in the File object.

File file = new File("z:\\results.txt");

I've implemented and tested this one; it should cover most bases:

public static <T> List<T> safeSubList(List<T> list, int fromIndex, int toIndex) {
    int size = list.size();
    if (fromIndex >= size || toIndex <= 0 || fromIndex >= toIndex) {
        return Collections.emptyList();
    }

    fromIndex = Math.max(0, fromIndex);
    toIndex = Math.min(size, toIndex);

    return list.subList(fromIndex, toIndex);
}

p:after {
  content: none;
}

This is a way to remove the :after and you can do the same for :before

In Swift 4.1 you can do:

func getDate() -> Date? {
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
    dateFormatter.timeZone = TimeZone.current
    dateFormatter.locale = Locale.current
    return dateFormatter.date(from: "2015-04-01T11:42:00") // replace Date String
}

When the LinkButton Enabled property is false it just renders a standard hyperlink. When you right click any disabled hyperlink you don't get the option to open in anything.

try

lbnkVidTtile1.Enabled = true;

I'm sorry if I misunderstood. Could I just make sure that you understand the purpose of a LinkButton? It is to give the appearance of a HyperLink but the behaviour of a Button. This means that it will have an anchor tag, but there is JavaScript wired up that performs a PostBack to the page. If you want to link to another page then it is recommended here that you use a standard HyperLink control.

I know the post is kinda old, but I have found a solution easy that works on Debian based distribution without compiling nginx from source.

First install nginx-extras package

sudo apt install nginx-extras

Then load the nginx http headers more module by editing nginx.conf and adding the following line inside the server block

load_module modules/ngx_http_headers_more_filter_module.so;

Once it's done you'll have access to both more_set_headers and more_clear_headers directives.

Your query is very close. You should be able to use the following which includes the subject in the final select list:

select u.name, u.subject, u.marks
from student s
unpivot
(
  marks
  for subject in (Maths, Science, English)
) u;

See SQL Fiddle with demo

Installation

pip install imageio-ffmpeg
pip install imageio

Code

import imageio
images = []
for filename in filenames:
    images.append(imageio.imread(filename))
imageio.mimsave('movie.mp4', images)

Quality is raised and size is reduced from 8Mb to 80Kb when saving as mp4 than gif

That could be a solution;

Array.Resize(ref array, newsize);
array[newsize - 1] = "newvalue"

But for dynamic sized array I would prefer list too.

An easy way to do:

function toggleButton(ref,bttnID){
    document.getElementById(bttnID).disabled= ((ref.value !== ref.defaultValue) ? false : true);
}


<input ... onkeyup="toggleButton(this,'bttnsubmit');">
<input ... disabled='disabled' id='bttnsubmit' ... >

Check out http://www.odata.org/

It defines the MERGE method, so in your case it would be something like this:

MERGE /customer/123

<customer>
   <status>DISABLED</status>
</customer>

Only the status property is updated and the other values are preserved.

First make sure the PHP files themselves are UTF-8 encoded.

The meta tag is ignored by some browser. If you only use ASCII-characters, it doesn't matter anyway.

http://en.wikipedia.org/wiki/List_of_HTTP_header_fields

header('Content-Type: text/html; charset=utf-8');

Assuming that your table name is city and your existing Primary Key is pk_city, you should be able to do the following:

ALTER TABLE city
DROP CONSTRAINT pk_city;

ALTER TABLE city
ADD CONSTRAINT pk_city PRIMARY KEY (city_id, buildtime, time);

Make sure that there are no records where time is NULL, otherwise you won't be able to re-create the constraint.

According to Android Sqlite get last insert row id there is another query:

SELECT rowid from your_table_name order by ROWID DESC limit 1

The most likely reason for the error is that the certificate authority that issued your SSL certificate is trusted on your desktop, but not on your mobile.

If you purchased the certificate from a common certification authority, it shouldn't be an issue - but if it is a less common one it is possible that your phone doesn't have it. You may need to accept it as a trusted publisher (although this is not ideal if you are pushing the site to the public as they won't be willing to do this.)

You might find looking at a list of Trusted CAs for Android helps to see if yours is there or not.

Are you sure that your configuration file (web.config) is at the right place and the connection string is really in the (generated) file? If you publish your file, the content of web.release.config might be copied.

The configuration and the access to the Connection string looks all right to me. I would always add a providername

<connectionStrings>
  <add name="Dbconnection" 
       connectionString="Server=localhost; Database=OnlineShopping; 
       Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>

STATIC_ROOT

The absolute path to the directory where ./manage.py collectstatic will collect static files for deployment. Example: STATIC_ROOT="/var/www/example.com/static/"

now the command ./manage.py collectstatic will copy all the static files(ie in static folder in your apps, static files in all paths) to the directory /var/www/example.com/static/. now you only need to serve this directory on apache or nginx..etc.

STATIC_URL

The URL of which the static files in STATIC_ROOT directory are served(by Apache or nginx..etc). Example: /static/ or http://static.example.com/

If you set STATIC_URL = 'http://static.example.com/', then you must serve the STATIC_ROOT folder (ie "/var/www/example.com/static/") by apache or nginx at url 'http://static.example.com/'(so that you can refer the static file '/var/www/example.com/static/jquery.js' with 'http://static.example.com/jquery.js')

Now in your django-templates, you can refer it by:

{% load static %}
<script src="{% static "jquery.js" %}"></script>

which will render:

<script src="http://static.example.com/jquery.js"></script>

If you want to use mapDispatchToProps without a mapStateToProps just use null for the first argument.

export default connect(null, mapDispatchToProps)(Start)

By default, html buttons submit a form.

This is due to the fact that even buttons located outside of a form act as submitters (see the W3Schools website: http://www.w3schools.com/tags/att_button_form.asp)

In other words, the button type is "submit" by default

<button type="submit">Button Text</button>

Therefore an easy way to get around this is to use the button type.

<button type="button">Button Text</button>

Other options include returning false at the end of the onclick or any other handler for when the button is clicked, or to using an < input> tag instead

To find out more, check out the Mozilla Developer Network's information on buttons: https://developer.mozilla.org/en/docs/Web/HTML/Element/button

You should \usepackage{longtable}.

Looking at the Jasmine source code sheds more light on the issue.

toBe is very simple and just uses the identity/strict equality operator, ===:

  function(actual, expected) {
    return {
      pass: actual === expected
    };
  }

toEqual, on the other hand, is nearly 150 lines long and has special handling for built in objects like String, Number, Boolean, Date, Error, Element and RegExp. For other objects it recursively compares properties.

This is very different from the behavior of the equality operator, ==. For example:

var simpleObject = {foo: 'bar'};
expect(simpleObject).toEqual({foo: 'bar'}); //true
simpleObject == {foo: 'bar'}; //false

var castableObject = {toString: function(){return 'bar'}};
expect(castableObject).toEqual('bar'); //false
castableObject == 'bar'; //true

You can use regular expressions like this:

SELECT * FROM pet WHERE name REGEXP 'Bob|Smith'; 

std based

#include <iostream>
#include <iomanip>
#include <sstream>
#include <string>

using namespace std;

#include <openssl/sha.h>
string sha256(const string str)
{
    unsigned char hash[SHA256_DIGEST_LENGTH];
    SHA256_CTX sha256;
    SHA256_Init(&sha256);
    SHA256_Update(&sha256, str.c_str(), str.size());
    SHA256_Final(hash, &sha256);
    stringstream ss;
    for(int i = 0; i < SHA256_DIGEST_LENGTH; i++)
    {
        ss << hex << setw(2) << setfill('0') << (int)hash[i];
    }
    return ss.str();
}

int main() {
    cout << sha256("1234567890_1") << endl;
    cout << sha256("1234567890_2") << endl;
    cout << sha256("1234567890_3") << endl;
    cout << sha256("1234567890_4") << endl;
    return 0;
}

if you need decimals can use this

DECLARE @Num NUMERIC(18, 7) = 19.1471985
SELECT FLOOR(@Num * 10000) / 10000

Output: 19.147100 Clear: 985 Add: 00

OR use this:

SELECT SUBSTRING(CONVERT(VARCHAR, @Num), 1, CHARINDEX('.', @Num) + 4)

Output: 19.1471 Clear: 985

I also had issues in running source in a Dockerfile

This runs perfectly fine for building CentOS 6.6 Docker container, but gave issues in Debian containers

RUN cd ansible && source ./hacking/env-setup

This is how I tackled it, may not be an elegant way but this is what worked for me

RUN echo "source /ansible/hacking/env-setup" >> /tmp/setup
RUN /bin/bash -C "/tmp/setup"
RUN rm -f /tmp/setup

Here's a complete working example based on your testing. Compare it to what you have currently to figure out where you are going wrong.

<html> 
  <head> 
    <title>Untitled Document</title> 
    <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
    <script type="text/javascript"> 
      $(document).ready( function() {
        $('#deletesuccess').delay(1000).fadeOut();
      });
    </script>
  </head> 
  <body>

Althugh you asked for Google Maps API, I suggest an open source, working, legal, free and crowdsourced API by Open street maps

https://nominatim.openstreetmap.org/search?q=Mumbai&format=json

Here is the API documentation for reference.

Edit: It looks like there are discrepancies occasionally, at least in terms of postal codes, when compared to the Google Maps API, and the latter seems to be more accurate. This was the case when validating addresses in Canada with the Canada Post search service, however, it might be true for other countries too.

I think ejs template engine is not properly installed on your machine. You just install the template engine using npm

npm install ejs --save

then include the following code in app.js

app.set('view engine', 'ejs')

This is a problem related permission. Make sure that the current user has access to the folder which contains installation files.

set print elements 0

From the GDB manual:

set print elements number-of-elements

Set a limit on how many elements of an array GDB will print. If GDB is printing a large array, it stops printing after it has printed the number of elements set by the set print elements command. This limit also applies to the display of strings. When GDB starts, this limit is set to 200. Setting number-of-elements to zero means that the printing is unlimited.

Since Jetpack, Single-Activity app is the preferred architecture. Usefull especially with the Navigation Architecture Component.

I viewed the Eclipse ADT documentation and found out the way to get around this issue. I was able to Update My SDK Tool to 22.0.4 (Latest Version).

Solution is: First Update ADT to 22.0.4(Latest version) and then Update SDK Tool to 22.0.4(Latest Version)

The above link says,

ADT 22.0.4 is designed for use with SDK Tools r22.0.4. If you haven't already installed SDK Tools r22.0.4 into your SDK, use the Android SDK Manager to do so

What I had to do was update my ADT to 22.0.4 (Latest Version) and then I was able to update SDK tool to 22.0.4. I thought only SDK Tool has been updated not ADT, so I was updating the SDK Tool with Older ADT Version (22.0.1).

How to Update your ADT to Latest Version

1. In Eclipse go to Help
2. Install New Software ---> Add
3. inside Add Repository write the Name: ADT (or whatever you want)
4. and Location: https://dl-ssl.google.com/android/eclipse/
5. after loading you should get Developer Tools and NDK Plugins
6. check both if you want to use the Native Developer Kit (NDK) in the future or check Developer Tool only
7. click Next
8. Finish

For iOS13

For background pushes in iOS13, you must set below parameters:

Use the below Power shell command to change the execution timeout (Request Timeout)

Please note that I have given this for default web site, before using these please change the site and then try to use this.

 Set-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST/Default Web Site'  -filter "system.web/httpRuntime" -name "executionTimeout" -value "00:01:40"

Or, You can use the below C# code to do the same thing

using System;
using System.Text;
using Microsoft.Web.Administration;

internal static class Sample {

    private static void Main() {

        using(ServerManager serverManager = new ServerManager()) { 
            Configuration config = serverManager.GetWebConfiguration("Default Web Site");

            ConfigurationSection httpRuntimeSection = config.GetSection("system.web/httpRuntime");
            httpRuntimeSection["executionTimeout"] = TimeSpan.Parse("00:01:40");

            serverManager.CommitChanges();
        }
    }
}

Or, you can use the JavaScript to do this.

var adminManager = new ActiveXObject('Microsoft.ApplicationHost.WritableAdminManager');
adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST/Default Web Site";

var httpRuntimeSection = adminManager.GetAdminSection("system.web/httpRuntime", "MACHINE/WEBROOT/APPHOST/Default Web Site");
httpRuntimeSection.Properties.Item("executionTimeout").Value = "00:01:40";

adminManager.CommitChanges();

Or, you can use the AppCmd commands.

appcmd.exe set config "Default Web Site" -section:system.web/httpRuntime /executionTimeout:"00:01:40" 

I know this is an old question but I thought I would provide an example using the srcdoc attribute as this is now widely supported and this is question is viewed often.

Using the srcdoc attribute, you can provide inline HTML to embed. It overrides the src attribute if supported. The browser will fall back to the src attribute if unsupported.

I would also recommend using the sandbox attribute to apply extra restrictions to the content in the frame. This is especially important if the HTML is not your own.

const iframe = document.createElement('iframe');_x000D_
const html = '<body>Foo</body>';_x000D_
iframe.srcdoc = html;_x000D_
iframe.sandbox = '';_x000D_
document.body.appendChild(iframe);

If you need to support older browsers, you can check for srcdoc support and fallback to one of the other methods from other answers.

function setIframeHTML(iframe, html) {_x000D_
  if (typeof iframe.srcdoc !== 'undefined') {_x000D_
    iframe.srcdoc = html;_x000D_
  } else {_x000D_
    iframe.sandbox = 'allow-same-origin';_x000D_
    iframe.contentWindow.document.open();_x000D_
    iframe.contentWindow.document.write(html);_x000D_
    iframe.contentWindow.document.close();_x000D_
  }_x000D_
}_x000D_
_x000D_
var iframe = document.createElement('iframe');_x000D_
iframe.sandbox = '';_x000D_
var html = '<body>Foo</body>';_x000D_
_x000D_
document.body.appendChild(iframe);_x000D_
setIframeHTML(iframe, html);

Try this code, I got it from here

$input = Array(1,2,3,1,2,3,4,5,6);
$input = array_map("unserialize", array_unique(array_map("serialize", $input)));

You are calling GridView.RenderControl(htmlTextWriter), hence the page raises an exception that a Server-Control was rendered outside of a Form.

You could avoid this execption by overriding VerifyRenderingInServerForm

public override void VerifyRenderingInServerForm(Control control)
{
  /* Confirms that an HtmlForm control is rendered for the specified ASP.NET
     server control at run time. */
}

See here and here.

I also had the same problem, and I saw a good solution in quora, using

sudo kill -9 PID.

see https://www.quora.com/How-do-I-kill-all-the-computer-processes-shown-in-nvidia-smi

I ended up using inipp which is not mentioned in this thread.

https://github.com/mcmtroffaes/inipp

Was a MIT licensed header only implementation which was simple enough to add to a project and 4 lines to use.

I used the following code:

import urllib

def read_text():
      quotes = urllib.urlopen("https://s3.amazonaws.com/udacity-hosted-downloads/ud036/movie_quotes.txt")
      contents_file = quotes.read()
      print contents_file

read_text()

Another way to do it:

    switch date1.compare(date2) {
        case .orderedAscending:
            break

        case .orderedDescending:
            break;

        case .orderedSame:
            break
    }

ole@T:~$ docker run -it --rm alpine /bin/ash
(inside container) / # 

Options used above:

• /bin/ash is Ash (Almquist Shell) provided by BusyBox
• --rm Automatically remove the container when it exits (docker run --help)
• -i Interactive mode (Keep STDIN open even if not attached)
• -t Allocate a pseudo-TTY

This will solve the problem of getting "Class 'PDO' not found" when you create a local php.ini file.

If you can't turn off magic quotes using the htaccess file (for reasons already given by Pete Bailey) just:

1. Create a text file
2. Rename it to 'php.ini'

3. Add the lines

   magic_quotes_gpc = Off
   magic_quotes_runtime = Off
   magic_quotes_sybase = Off
   extension=pdo.so
   extension=pdo_mysql.so

4. Save it to the directory/ies in which your scripts are executing.

Update: if you want to have just one copy of the new php.ini file then add this line to your root .htaccess file:

SetEnv PHPRC /path/to/site/root/public_html/php.ini

Obviously you need to move the ini file to this location of it's not there already.

Hope that saves someone the 2 hours it's just taken me!

It took a while to put together a solution for this, but have found this is the easiest way to get it to work in the way that you describe. There could be better ways to do this, but since you haven't posted your activity code I will have to improvise and assume you have a list like this at the start of your activity:

private List<String> items = db.getItems();

ExampleActivity.java

private List<String> items;

private Menu menu;

@Override
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.example, menu);

    this.menu = menu;

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));

        search.setOnQueryTextListener(new OnQueryTextListener() { 

            @Override 
            public boolean onQueryTextChange(String query) {

                loadHistory(query);

                return true; 

            } 

        });

    }

    return true;

}

// History
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void loadHistory(String query) {

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        // Cursor
        String[] columns = new String[] { "_id", "text" };
        Object[] temp = new Object[] { 0, "default" };

        MatrixCursor cursor = new MatrixCursor(columns);

        for(int i = 0; i < items.size(); i++) {

            temp[0] = i;
            temp[1] = items.get(i);

            cursor.addRow(temp);

        }

        // SearchView
        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        final SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSuggestionsAdapter(new ExampleAdapter(this, cursor, items));

    }

}

Now you need to create an adapter extended from CursorAdapter:

ExampleAdapter.java

public class ExampleAdapter extends CursorAdapter {

    private List<String> items;

    private TextView text;

    public ExampleAdapter(Context context, Cursor cursor, List<String> items) {

        super(context, cursor, false);

        this.items = items;

    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {

        text.setText(items.get(cursor.getPosition()));

    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View view = inflater.inflate(R.layout.item, parent, false);

        text = (TextView) view.findViewById(R.id.text);

        return view;

    }

}

A better way to do this is if your list data is from a database, you can pass the Cursor returned by database functions directly to ExampleAdapter and use the relevant column selector to display the column text in the TextView referenced in the adapter.

Please note: when you import CursorAdapter don't import the Android support version, import the standard android.widget.CursorAdapter instead.

The adapter will also require a custom layout:

res/layout/item.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView
        android:id="@+id/item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</RelativeLayout>

You can now customize list items by adding additional text or image views to the layout and populating them with data in the adapter.

This should be all, but if you haven't done this already you need a SearchView menu item:

res/menu/example.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/search"
        android:title="@string/search"
        android:showAsAction="ifRoom"
        android:actionViewClass="android.widget.SearchView" />

</menu>

Then create a searchable configuration:

res/xml/searchable.xml

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/search"
    android:hint="@string/search" >
</searchable>

Finally add this inside the relevant activity tag in the manifest file:

AndroidManifest.xml

<intent-filter>
    <action android:name="android.intent.action.SEARCH" />
</intent-filter>

<meta-data
    android:name="android.app.default_searchable"
    android:value="com.example.ExampleActivity" />
<meta-data
    android:name="android.app.searchable"
    android:resource="@xml/searchable" />

Please note: The @string/search string used in the examples should be defined in values/strings.xml, also don't forget to update the reference to com.example for your project.

Taking for granted that the JSON you posted is actually what you are seeing in the browser, then the problem is the JSON itself.

The JSON snippet you have posted is malformed.

You have posted:

[{
        "name" : "shopqwe",
        "mobiles" : [],
        "address" : {
            "town" : "city",
            "street" : "streetqwe",
            "streetNumber" : "59",
            "cordX" : 2.229997,
            "cordY" : 1.002539
        },
        "shoe"[{
                "shoeName" : "addidas",
                "number" : "631744030",
                "producent" : "nike",
                "price" : 999.0,
                "sizes" : [30.0, 35.0, 38.0]
            }]

while the correct JSON would be:

[{
        "name" : "shopqwe",
        "mobiles" : [],
        "address" : {
            "town" : "city",
            "street" : "streetqwe",
            "streetNumber" : "59",
            "cordX" : 2.229997,
            "cordY" : 1.002539
        },
        "shoe" : [{
                "shoeName" : "addidas",
                "number" : "631744030",
                "producent" : "nike",
                "price" : 999.0,
                "sizes" : [30.0, 35.0, 38.0]
            }
        ]
    }
]

To answer a little more conceptually:

SelectedValuePath defines which property (by its name) of the objects bound to the ListBox's ItemsSource will be used as the item's SelectedValue.

For example, if your ListBox is bound to a collection of Person objects, each of which has Name, Age, and Gender properties, SelectedValuePath=Name will cause the value of the selected Person's Name property to be returned in SelectedValue.

Note that if you override the ListBox's ControlTemplate (or apply a Style) that specifies what property should display, SelectedValuePath cannot be used.

SelectedItem, meanwhile, returns the entire Person object currently selected.

(Here's a further example from MSDN, using TreeView)

Update: As @Joe pointed out, the DisplayMemberPath property is unrelated to the Selected* properties. Its proper description follows:

Note that these values are distinct from DisplayMemberPath (which is defined on ItemsControl, not Selector), but that property has similar behavior to SelectedValuePath: in the absence of a style/template, it identifies which property of the object bound to item should be used as its string representation.

Another tip that would help a lot is that to set the current directory to a different drive one would have to use %~d0 first, then cd %~dp0. This will change the directory to the batch file's drive, then change to its folder.

Alternatively, for #oneLinerLovers, as @Omni pointed out in the comments cd /d %~dp0 will change both the drive and directory :)

Hope this helps someone.

For your iphone You could use in your head balise :

"width=device-width"

File myFile = new File(uri.toString());
myFile.getAbsolutePath()

should return u the correct path

EDIT

As @Tron suggested the working code is

File myFile = new File(uri.getPath());
myFile.getAbsolutePath()

There are not many good reasons this would fail, especially the regsvr32 step. Run dumpbin /exports on that dll. If you don't see DllRegisterServer then you've got a corrupt install. It should have more side-effects, you wouldn't be able to build C/C++ projects anymore.

One standard failure mode is running this on a 64-bit operating system. This is 32-bit unmanaged code, you would indeed get the 'class not registered' exception. Project + Properties, Build tab, change Platform Target to x86.

User match = users.stream().filter((user) -> user.getId()== 1).findAny().orElseThrow(()-> new IllegalArgumentException());

Android 1.5 and 1.6 do not offer this thumbnails, but 2.0 does, as seen on the official release notes:

Media

• MediaScanner now generates thumbnails for all images when they are inserted into MediaStore.
• New Thumbnail API for retrieving image and video thumbnails on demand.

It seems that <TouchableHighlight> must have exactly one child. The docs say that it supports only one child and more than one must be wrapped in a <View>, but not that it must have at least (and most) one child. I just wanted to have a plain coloured button with no text/image, so I didn't deem it necessary to add a child.

I'll try to update the docs to indicate this.

From the sed man page:

Normally, sed cyclically copies a line of input, not including its terminating newline character, into a pattern space, (unless there is something left after a "D" function), applies all of the commands with addresses that select that pattern space, copies the pattern space to the standard output, appending a newline, and deletes the pattern space.

It's operating on the line without the newline present, so the pattern you have there can't ever match. You need to do something else - like match against $ (end-of-line) or ^ (start-of-line).

Here's an example of something that worked for me:

$ cat > states
California
Massachusetts
Arizona
$ sed -e 's/$/\
> /' states
California

Massachusetts

Arizona

I typed a literal newline character after the \ in the sed line.

They can be differentiated with where they are coming from or which developers they're targeting mainly.

Groovy is a bit like scripting version of Java. Long time Java programmers feel at home when building agile applications backed by big architectures. Groovy on Grails is, as the name suggests similar to the Rails framework. For people who don't want to bother with Java's verbosity all the time.

Scala is an object oriented and functional programming language and Ruby or Python programmers may feel more closer to this one. It employs quite a lot of common good ideas found in these programming languages.

Clojure is a dialect of the Lisp programming language so Lisp, Scheme or Haskell developers may feel at home while developing with this language.

You want:

insert into prices (group, id, price)
select 
    7, articleId, 1.50
from article where name like 'ABC%';

where you just hardcode the constant fields.

Add a Kotlin Extension

If you are going to be doing this frequently, adding an extension makes your code more readable. Button extends TextView; use Button if you want to be more narrow.

fun TextView.leftDrawable(@DrawableRes id: Int = 0) {
    this.setCompoundDrawablesWithIntrinsicBounds(id, 0, 0, 0)
}

To use the extension, simply call

view.leftDrawable(R.drawable.my_drawable)

Anytime you need to clear, don't pass a param or make another extension called removeDrawables

false|tee fileToTruncate

may work as well

This error might be also for plugin versions. You can fix it in the .POM file like the followings:

If logical test is against a single column then you could use something like

USE AdventureWorks2012;  
GO  
SELECT   ProductNumber, Category =  
      CASE ProductLine  
         WHEN 'R' THEN 'Road'  
         WHEN 'M' THEN 'Mountain'  
         WHEN 'T' THEN 'Touring'  
         WHEN 'S' THEN 'Other sale items'  
         ELSE 'Not for sale'  
      END,  
   Name  
FROM Production.Product  
ORDER BY ProductNumber;  
GO

I think we need to write more specific media query. Make sure if you write one media query it should be not effect to other view (Mob,Tab,Desk) otherwise it can be trouble. I would like suggest to write one basic media query for respective device which cover both view and one orientation media query that you can specific code more about orientation view its for good practice. we Don't need to write both media orientation query at same time. You can refer My below example. I am sorry if my English writing is not much good. Ex:

For Mobile

@media screen and (max-width:767px) {

..This is basic media query for respective device.In to this media query  CSS code cover the both view landscape and portrait view.

}


@media screen and (min-width:320px) and (max-width:767px) and (orientation:landscape) {


..This orientation media query. In to this orientation media query you can specify more about CSS code for landscape view.

}

For Tablet

@media screen and (max-width:1024px){
..This is basic media query for respective device.In to this media query  CSS code cover the both view landscape and portrait view.
}
@media screen and (min-width:768px) and (max-width:1024px) and (orientation:landscape){

..This orientation media query. In to this orientation media query you can specify more about CSS code for landscape view.

}

I will elaborate on what robodo said in one of the comments above, a really quick and good looking and what is more important, responsive (not fixed height) approach that does not involve any hacks is to use flexbox. If you're not limited by browsers support it's a great solution.

HTML

<body>
  <div class="site-content">
    Site content
  </div>
  <footer class="footer">
    Footer content
  </footer>
</body>

CSS

html {
  height: 100%;
}
body {
  min-height: 100%;
  display: flex;
  flex-direction: column;
}
.site-content {
  flex: 1;
}

Browser support can be checked here: http://caniuse.com/#feat=flexbox

More common problem solutions using flexbox: https://github.com/philipwalton/solved-by-flexbox

If you're using Angular you can use the following code to do the same.

in component.html

<table id="" datatable [dtOptions]="dtOptions" class="table dataTable">

and in your component.ts

 dtOptions: any = {}


 this.dtOptions = {
  searching: true,    //enables the search bar
  info: false        //disables the entry information
}

You could use ajaxStart and ajaxStop to keep track of when requests are active.

"Conflicts" mean "parallel evolutions of a same content". So if it goes "all to hell" during a merge, it means you have massive evolutions on the same set of files.

The reason why a rebase is then better than a merge is that:

• you rewrite your local commit history with the one of the master (and then reapply your work, resolving any conflict then)
• the final merge will certainly be a "fast forward" one, because it will have all the commit history of the master, plus only your changes to reapply.

I confirm that the correct workflow in that case (evolutions on common set of files) is rebase first, then merge.

However, that means that, if you push your local branch (for backup reason), that branch should not be pulled (or at least used) by anyone else (since the commit history will be rewritten by the successive rebase).

On that topic (rebase then merge workflow), barraponto mentions in the comments two interesting posts, both from randyfay.com:

• A Rebase Workflow for Git: reminds us to fetch first, rebase:

Using this technique, your work always goes on top of the public branch like a patch that is up-to-date with current HEAD.

(a similar technique exists for bazaar)

• Avoiding Git Disasters: A Gory Story: about the dangers of git push --force (instead of a git pull --rebase for instance)

I'm using this solution:

@interface Model
+ (int) value;
+ (void) setValue:(int)val;
@end

@implementation Model
static int value;
+ (int) value
{ @synchronized(self) { return value; } }
+ (void) setValue:(int)val
{ @synchronized(self) { value = val; } }
@end

And i found it extremely useful as a replacement of Singleton pattern.

To use it, simply access your data with dot notation:

Model.value = 1;
NSLog(@"%d = value", Model.value);

shorter ios swift 4 version:

@IBAction func checkBoxBtnTapped(_ sender: UIButton) {
        if checkBoxBtn.isSelected {
            checkBoxBtn.setBackgroundImage(#imageLiteral(resourceName: "ic_signup_unchecked"), for: .normal)
        } else {
            checkBoxBtn.setBackgroundImage(#imageLiteral(resourceName: "ic_signup_checked"), for:.normal)
        }
        checkBoxBtn.isSelected = !checkBoxBtn.isSelected
    }

To clarify. What is important to know is that:

• Yes, you have to pass a Javascript Date object.
• Yes, it has to be ISODate friendly
• Yes, from my experience getting this to work, you need to manipulate the date to ISO
• Yes, working with dates is generally always a tedious process, and mongo is no exception

Here is a working snippet of code, where we do a little bit of date manipulation to ensure Mongo (here i am using mongoose module and want results for rows whose date attribute is less than (before) the date given as myDate param) can handle it correctly:

var inputDate = new Date(myDate.toISOString());
MyModel.find({
    'date': { $lte: inputDate }
})

I've found this works:

Rows(CStr(iVar1) & ":" & CStr(iVar2)).Select

According to the official documentation, a click on any link in WebView launches an application that handles URLs, which by default is a browser. You need to override the default behavior like this

    myWebView.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            return false;
        }
    });

if you have a string of date, then you should try this.

const FORMAT = "YYYY ddd MMM DD HH:mm";

const theDate = moment("2019 Tue Apr 09 13:30", FORMAT);
// Tue Apr 09 2019 13:30:00 GMT+0300

const theDate1 = moment("2019 Tue Apr 09 13:30", FORMAT).format('LL')
// April 9, 2019

or try this :

const theDate1 = moment("2019 Tue Apr 09 13:30").format(FORMAT);

here is example of @dynamic

#import <Foundation/Foundation.h>

        NSString *obj;
        [invocation getArgument:&obj atIndex:2];
        [data setObject:obj forKey:key];
    } else {
        NSString *obj = [data objectForKey:key];
        [invocation setReturnValue:&obj];
    }
}

@end

int main(int argc, char **argv)
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

I installed System.Configuration.ConfigurationManager from Nuget into my .net core 2.2 application.

I then reference using System.Configuration;

Next, I changed

WebConfigurationManager.AppSettings

to ..

ConfigurationManager.AppSettings

So far I believe this is correct. 4.5.0 is typical with .net core 2.2

I have not had any issues with this.

To conditionally check the length of the string, use CASE.

        END  As Comments

First you need to declare your resources in dispatcher-servlet file like this :

<mvc:resources mapping="/resources/**" location="/resources/folder/" />

Any request with url mapping /resources/** will directly look for /resources/folder/.

Now in jsp file you need to include your css file like this :

<link href="<c:url value="/resources/css/main.css" />" rel="stylesheet">

Similarly you can include js files.

Hope this solves your problem.

One line of jQuery does it all!

DISCLAIMER: This answer was written in 2008.

Since then, PHP has given us password_hash and password_verify and, since their introduction, they are the recommended password hashing & checking method.

The theory of the answer is still a good read though.

TL;DR

Don'ts

• Don't limit what characters users can enter for passwords. Only idiots do this.
• Don't limit the length of a password. If your users want a sentence with supercalifragilisticexpialidocious in it, don't prevent them from using it.
• Don't strip or escape HTML and special characters in the password.
• Never store your user's password in plain-text.
• Never email a password to your user except when they have lost theirs, and you sent a temporary one.
• Never, ever log passwords in any manner.
• Never hash passwords with SHA1 or MD5 or even SHA256! Modern crackers can exceed 60 and 180 billion hashes/second (respectively).
• Don't mix bcrypt and with the raw output of hash(), either use hex output or base64_encode it. (This applies to any input that may have a rogue \0 in it, which can seriously weaken security.)

Dos

• Use scrypt when you can; bcrypt if you cannot.
• Use PBKDF2 if you cannot use either bcrypt or scrypt, with SHA2 hashes.
• Reset everyone's passwords when the database is compromised.
• Implement a reasonable 8-10 character minimum length, plus require at least 1 upper case letter, 1 lower case letter, a number, and a symbol. This will improve the entropy of the password, in turn making it harder to crack. (See the "What makes a good password?" section for some debate.)

Why hash passwords anyway?

The objective behind hashing passwords is simple: preventing malicious access to user accounts by compromising the database. So the goal of password hashing is to deter a hacker or cracker by costing them too much time or money to calculate the plain-text passwords. And time/cost are the best deterrents in your arsenal.

Another reason that you want a good, robust hash on a user accounts is to give you enough time to change all the passwords in the system. If your database is compromised you will need enough time to at least lock the system down, if not change every password in the database.

Jeremiah Grossman, CTO of Whitehat Security, stated on White Hat Security blog after a recent password recovery that required brute-force breaking of his password protection:

Interestingly, in living out this nightmare, I learned A LOT I didn’t know about password cracking, storage, and complexity. I’ve come to appreciate why password storage is ever so much more important than password complexity. If you don’t know how your password is stored, then all you really can depend upon is complexity. This might be common knowledge to password and crypto pros, but for the average InfoSec or Web Security expert, I highly doubt it.

(Emphasis mine.)

What makes a good password anyway?

Entropy. (Not that I fully subscribe to Randall's viewpoint.)

In short, entropy is how much variation is within the password. When a password is only lowercase roman letters, that's only 26 characters. That isn't much variation. Alpha-numeric passwords are better, with 36 characters. But allowing upper and lower case, with symbols, is roughly 96 characters. That's a lot better than just letters. One problem is, to make our passwords memorable we insert patterns—which reduces entropy. Oops!

Password entropy is approximated easily. Using the full range of ascii characters (roughly 96 typeable characters) yields an entropy of 6.6 per character, which at 8 characters for a password is still too low (52.679 bits of entropy) for future security. But the good news is: longer passwords, and passwords with unicode characters, really increase the entropy of a password and make it harder to crack.

There's a longer discussion of password entropy on the Crypto StackExchange site. A good Google search will also turn up a lot of results.

In the comments I talked with @popnoodles, who pointed out that enforcing a password policy of X length with X many letters, numbers, symbols, etc, can actually reduce entropy by making the password scheme more predictable. I do agree. Randomess, as truly random as possible, is always the safest but least memorable solution.

So far as I've been able to tell, making the world's best password is a Catch-22. Either its not memorable, too predictable, too short, too many unicode characters (hard to type on a Windows/Mobile device), too long, etc. No password is truly good enough for our purposes, so we must protect them as though they were in Fort Knox.

Best practices

Bcrypt and scrypt are the current best practices. Scrypt will be better than bcrypt in time, but it hasn't seen adoption as a standard by Linux/Unix or by webservers, and hasn't had in-depth reviews of its algorithm posted yet. But still, the future of the algorithm does look promising. If you are working with Ruby there is an scrypt gem that will help you out, and Node.js now has its own scrypt package. You can use Scrypt in PHP either via the Scrypt extension or the Libsodium extension (both are available in PECL).

I highly suggest reading the documentation for the crypt function if you want to understand how to use bcrypt, or finding yourself a good wrapper or use something like PHPASS for a more legacy implementation. I recommend a minimum of 12 rounds of bcrypt, if not 15 to 18.

I changed my mind about using bcrypt when I learned that bcrypt only uses blowfish's key schedule, with a variable cost mechanism. The latter lets you increase the cost to brute-force a password by increasing blowfish's already expensive key schedule.

Average practices

I almost can't imagine this situation anymore. PHPASS supports PHP 3.0.18 through 5.3, so it is usable on almost every installation imaginable—and should be used if you don't know for certain that your environment supports bcrypt.

But suppose that you cannot use bcrypt or PHPASS at all. What then?

Try an implementation of PDKBF2 with the maximum number of rounds that your environment/application/user-perception can tolerate. The lowest number I'd recommend is 2500 rounds. Also, make sure to use hash_hmac() if it is available to make the operation harder to reproduce.

Future Practices

Coming in PHP 5.5 is a full password protection library that abstracts away any pains of working with bcrypt. While most of us are stuck with PHP 5.2 and 5.3 in most common environments, especially shared hosts, @ircmaxell has built a compatibility layer for the coming API that is backward compatible to PHP 5.3.7.

Cryptography Recap & Disclaimer

The computational power required to actually crack a hashed password doesn't exist. The only way for computers to "crack" a password is to recreate it and simulate the hashing algorithm used to secure it. The speed of the hash is linearly related to its ability to be brute-forced. Worse still, most hash algorithms can be easily parallelized to perform even faster. This is why costly schemes like bcrypt and scrypt are so important.

You cannot possibly foresee all threats or avenues of attack, and so you must make your best effort to protect your users up front. If you do not, then you might even miss the fact that you were attacked until it's too late... and you're liable. To avoid that situation, act paranoid to begin with. Attack your own software (internally) and attempt to steal user credentials, or modify other user's accounts or access their data. If you don't test the security of your system, then you cannot blame anyone but yourself.

Lastly: I am not a cryptographer. Whatever I've said is my opinion, but I happen to think it's based on good ol' common sense ... and lots of reading. Remember, be as paranoid as possible, make things as hard to intrude as possible, and then, if you are still worried, contact a white-hat hacker or cryptographer to see what they say about your code/system.

INTERSECT needs to be emulated in MySQL:

SELECT  'robot' AS `set`, r.*
FROM    robot r
WHERE   ROW(r.col1, r.col2, …) NOT IN
        (
        SELECT  col1, col2, ...
        FROM    tbd_robot
        )
UNION ALL
SELECT  'tbd_robot' AS `set`, t.*
FROM    tbd_robot t
WHERE   ROW(t.col1, t.col2, …) NOT IN
        (
        SELECT  col1, col2, ...
        FROM    robot
        )

You can use this QString constructor for conversion from QByteArray to QString:

QString(const QByteArray &ba)

QByteArray data;
QString DataAsString = QString(data);

You can listen to the afterprint event.

https://developer.mozilla.org/en-US/docs/Web/API/window.onafterprint

window.onafterprint = function(){
   console.log("Printing completed...");
}

It may be possible to use window.matchMedia to get this functionality in another way.

(function() {

    var beforePrint = function() {
        console.log('Functionality to run before printing.');
    };

    var afterPrint = function() {
        console.log('Functionality to run after printing');
    };

    if (window.matchMedia) {
        var mediaQueryList = window.matchMedia('print');
        mediaQueryList.addListener(function(mql) {
            if (mql.matches) {
                beforePrint();
            } else {
                afterPrint();
            }
        });
    }

    window.onbeforeprint = beforePrint;
    window.onafterprint = afterPrint;

}());

The cleanest solution - also purely CSS - would be using calc and vh.

The middle div's heigh will be calculated thusly:

#middle-div { 
height: calc(100vh - 46px); 
}

That is, 100% of the viewport height minus the 2*23px. This will ensure that the page loads properly and is dynamic(demo here).

Also remember to use box-sizing, so the paddings and borders don't make the divs outfill the viewport.

It is also possible to open the pdf link in a new window and let the browser handle the rest:

window.open(pdfUrl, '_blank');

or:

window.open(pdfUrl);

instead of

$('html, body').animate({scrollTop:xxx}, 'slow');

use

$('html, body').animate({scrollTop:$('#div_id').position().top}, 'slow');

this will return the absolute top position of whatever element you select as #div_id

As far as I know, display: inline-block is what you probably need. That will make it seem like it's sort of inline but still allow you to use things like margins and such.

You can show/hide with Value or Class name. Check the below link with working example.
Show/hide jquery chosen options with value or with class name.

Try something like this - it works for the cases you have mentioned.

select * from tbl
where answer like '%[0-9]%'
and answer not like '%[:]%'
and answer not like '%[A-Z]%'

If you are Clion/anyOtherJetBrainsIDE user, and yourFile.exe cause this problem, just delete it and let the app create and link it with libs from a scratch. It helps.

The project facets should be derived automagically by the M2Eclipse plugin from the POM configuration. If you make some changes to the POM and need Eclipse to take them into account, right-click on your project, then go to Maven > Update Project Configuration. You should not set project facets manually.

Use 'Smalldatetime' data type

select convert(smalldatetime, getdate())

Here are two methods to get more than 1 column in a scalar subquery (or inline subquery) and querying the lookup table only once. This is a bit convoluted but can be the very efficient in some special cases.

1. You can use concatenation to get several columns at once:

   SELECT x, 
          regexp_substr(yz, '[^^]+', 1, 1) y,
          regexp_substr(yz, '[^^]+', 1, 2) z
     FROM (SELECT a.x,
                  (SELECT b.y || '^' || b.z yz
                     FROM b
                    WHERE b.v = a.v)
                     yz
             FROM a)
   

   You would need to make sure that no column in the list contain the separator character.

2. You could also use SQL objects:

   CREATE OR REPLACE TYPE b_obj AS OBJECT (y number, z number);
   
   SELECT x, 
          v.yz.y y,
          v.yz.z z
     FROM (SELECT a.x,
                  (SELECT b_obj(y, z) yz
                     FROM b
                    WHERE b.v = a.v)
                     yz
             FROM a) v
   

You can use

call script.bat

or just

script.bat

In MVC 3 I had to add:

using System.ComponentModel.DataAnnotations;

among usings when adding properties:

[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]

Especially if you are adding these properties in .edmx file like me. I found that by default .edmx files don't have this using so adding only propeties is not enough.

I usually use a bat script for that. Here's what I typically use:

@echo off
set d=%~dp0
java -Xmx400m -cp "%d%myapp.jar;%d%libs/mylib.jar" my.main.Class %*

The %~dp0 extract the directory where the .bat is located. This allows the bat to find the locations of the jars without requiring any special environment variables nor the setting of the PATH variable.

EDIT: Added quotes to the classpath. Otherwise, as Joey said, "fun things can happen with spaces"

By using Axios interceptor:

const service = axios.create({
  timeout: 20000 // request timeout
});

// request interceptor

service.interceptors.request.use(
  config => {
    // Do something before request is sent

    config.headers["Authorization"] = "bearer " + getToken();
    return config;
  },
  error => {
    Promise.reject(error);
  }
);

The simplest one got to be:

def html = "http://google.com".toURL().text

SEL is a type that represents a selector in Objective-C. The @selector() keyword returns a SEL that you describe. It's not a function pointer and you can't pass it any objects or references of any kind. For each variable in the selector (method), you have to represent that in the call to @selector. For example:

-(void)methodWithNoParameters;
SEL noParameterSelector = @selector(methodWithNoParameters);

-(void)methodWithOneParameter:(id)parameter;
SEL oneParameterSelector = @selector(methodWithOneParameter:); // notice the colon here

-(void)methodWIthTwoParameters:(id)parameterOne and:(id)parameterTwo;
SEL twoParameterSelector = @selector(methodWithTwoParameters:and:); // notice the parameter names are omitted

Selectors are generally passed to delegate methods and to callbacks to specify which method should be called on a specific object during a callback. For instance, when you create a timer, the callback method is specifically defined as:

-(void)someMethod:(NSTimer*)timer;

So when you schedule the timer you would use @selector to specify which method on your object will actually be responsible for the callback:

@implementation MyObject

-(void)myTimerCallback:(NSTimer*)timer
{
    // do some computations
    if( timerShouldEnd ) {
      [timer invalidate];
    }
}

@end

// ...

int main(int argc, const char **argv)
{
    // do setup stuff
    MyObject* obj = [[MyObject alloc] init];
    SEL mySelector = @selector(myTimerCallback:);
    [NSTimer scheduledTimerWithTimeInterval:30.0 target:obj selector:mySelector userInfo:nil repeats:YES];
    // do some tear-down
    return 0;
}

In this case you are specifying that the object obj be messaged with myTimerCallback every 30 seconds.

Suppose if you want to replace the above with some other info.

COMMAND(:%s/\/sys\/sim\/source\/gm\/kg\/jl\/ls\/owow\/lsal/sys.pkg.mpu.umc.kdk./g)

In this the above will be get replaced with (sys.pkg.mpu.umc.kdk.) .

Try:

array[i] = Convert.ToDouble(Console.Readline());

You might also want to use double.TryParse() to make sure that the user didn't enter bogus text and handle that somehow.

I don't know ASP.NET very well, but can you use the ternary operator?

http://en.wikipedia.org/wiki/Ternary_operation

Something like: (x=Eval("item")) == Null ? 0 : x

First() is causing this if your select returns 0 rows. You either have to catch that exception, or use FirstOrDefault() which will return null in case of no elements.

There is nothing in JDK to do this.

  static String[] suffixes =
  //    0     1     2     3     4     5     6     7     8     9
     { "th", "st", "nd", "rd", "th", "th", "th", "th", "th", "th",
  //    10    11    12    13    14    15    16    17    18    19
       "th", "th", "th", "th", "th", "th", "th", "th", "th", "th",
  //    20    21    22    23    24    25    26    27    28    29
       "th", "st", "nd", "rd", "th", "th", "th", "th", "th", "th",
  //    30    31
       "th", "st" };

 Date date = new Date();
 SimpleDateFormat formatDayOfMonth  = new SimpleDateFormat("d");
 int day = Integer.parseInt(formatDateOfMonth.format(date));
 String dayStr = day + suffixes[day];

Or using Calendar:

 Calendar c = Calendar.getInstance();
 c.setTime(date);
 int day = c.get(Calendar.DAY_OF_MONTH);
 String dayStr = day + suffixes[day];

Per comments by @thorbjørn-ravn-andersen, a table like this can be helpful when localizing:

  static String[] suffixes =
     {  "0th",  "1st",  "2nd",  "3rd",  "4th",  "5th",  "6th",  "7th",  "8th",  "9th",
       "10th", "11th", "12th", "13th", "14th", "15th", "16th", "17th", "18th", "19th",
       "20th", "21st", "22nd", "23rd", "24th", "25th", "26th", "27th", "28th", "29th",
       "30th", "31st" };

To install PDT (PHP Development Tools) for PHP development environment is better in Eclipse. The following are the steps to install PDT in Eclipse (I'm considering version 3.7 (Indigo)):

1. Open Eclipse (in my case Eclipse Indigo).
2. Go to Help --> Install New Software...
3. Expand the "Work with" drop down and select "Indigo - http://download.eclipse.org/releases/indigo".
4. Expand "Programming Languages" from the list.
5. Check PHP Development Tools (PDT) SDK Feature.
6. Click "Next >" at the bottom and follow the further instruction of Eclipse.
7. After successful installation of PDT: Go to Window --> Preferences and see the list as PHP at left panel.

When you're using Data Type: int you can select the row which you want to get autoincremented and go to the column properties tag. There you can set the identity to 'yes'. The starting value for autoincrement can also be edited there. Hope I could help ;)

If you're using cygwin, the syntax is slightly different for the basename command.

I strongly recommend placing the video in a project website created with GitHub Pages instead of the readme, like described in VonC's answer; it will be a lot better than any of these ideas. But if you need a quick fix just like I needed, here are some suggestions.

Use a gif

See aloisdg's answer, result is awesome, gifs are rendered on github's readme ;)

Use a video player picture

You could trick the user into thinking the video is on the readme page with a picture. It sounds like an ad trick, it's not perfect, but it works and it's funny ;).

Example:

[![Watch the video](https://i.imgur.com/vKb2F1B.png)](https://youtu.be/vt5fpE0bzSY)

Result:

Use youtube's preview picture

You can also use the picture generated by youtube for your video.

For youtube urls in the form of:

https://www.youtube.com/watch?v=<VIDEO ID>
https://youtu.be/<VIDEO URL>

The preview urls are in the form of:

https://img.youtube.com/vi/<VIDEO ID>/maxresdefault.jpg
https://img.youtube.com/vi/<VIDEO ID>/hqdefault.jpg

Example:

[![Watch the video](https://img.youtube.com/vi/T-D1KVIuvjA/maxresdefault.jpg)](https://youtu.be/T-D1KVIuvjA)

Result:

Use asciinema

If your use case is something that runs in a terminal, asciinema lets you record a terminal session and has nice markdown embedding.

Hit share button and copy the markdown snippet.

Example:

[![asciicast](https://asciinema.org/a/113463.png)](https://asciinema.org/a/113463)

Result:

Considering that XML data comes from a table 'table' and is stored in a column 'field': use the XML methods, extract values with xml.value(), project nodes with xml.nodes(), use CROSS APPLY to join:

SELECT 
    p.value('(./firstName)[1]', 'VARCHAR(8000)') AS firstName,
    p.value('(./lastName)[1]', 'VARCHAR(8000)') AS lastName
FROM table 
    CROSS APPLY field.nodes('/person') t(p)

You can ditch the nodes() and cross apply if each field contains exactly one element 'person'. If the XML is a variable you select FROM @variable.nodes(...) and you don't need the cross apply.

That's because that's an SQL function, not PHP. You can use PDO::lastInsertId().

Like:

$stmt = $db->prepare("...");
$stmt->execute();
$id = $db->lastInsertId();

If you want to do it with SQL instead of the PDO API, you would do it like a normal select query:

$stmt = $db->query("SELECT LAST_INSERT_ID()");
$lastId = $stmt->fetchColumn();

Use sonar.coverage.exclusions property.

mvn clean install -Dsonar.coverage.exclusions=**/*ToBeExcluded.java

This should exclude the classes from coverage calculation.

RAILS_ENV=production rails s

OR

rails s -e production

By default environment is developement.

I have tried &amp, but it didn't work. Based on Wim ten Brink's answer I tried &amp;amp and it worked.

One of my fellow developers suggested me to use &#x26; and that worked regardless of how many times it may be rendered.

Have a look at the WebRequestHandler Class and its ServerCertificateValidationCallback Property:

using (var handler = new WebRequestHandler())
{
    handler.ServerCertificateValidationCallback = ...

    using (var client = new HttpClient(handler))
    {
        ...
    }
}

For those of you using Spring, you can simply reference any classpath-resource using the classpath-protocol. So in case of the wsdlLocation, this becomes:

<wsdlLocation>classpath:META-INF/webservice.wsdl</wsdlLocation>

Note that is not standard Java behavior. See also: http://docs.spring.io/spring/docs/current/spring-framework-reference/html/resources.html

I just wrote a directive to handle this, so you can simply add the attribute bs-active-link to the parent <ul> element, and any time the route changed, it will find the matching link, and add the active class to the corresponding <li>.

You can see it in action here: http://jsfiddle.net/8mcedv3b/

Example HTML:

<ul class="nav navbar-nav" bs-active-link>
  <li><a href="/home">Home</a></li>
  <li><a href="/contact">Contact</a></li>
</ul>

Javascript:

angular.module('appName')
.directive('bsActiveLink', ['$location', function ($location) {
return {
    restrict: 'A', //use as attribute 
    replace: false,
    link: function (scope, elem) {
        //after the route has changed
        scope.$on("$routeChangeSuccess", function () {
            var hrefs = ['/#' + $location.path(),
                         '#' + $location.path(), //html5: false
                         $location.path()]; //html5: true
            angular.forEach(elem.find('a'), function (a) {
                a = angular.element(a);
                if (-1 !== hrefs.indexOf(a.attr('href'))) {
                    a.parent().addClass('active');
                } else {
                    a.parent().removeClass('active');   
                };
            });     
        });
    }
}
}]);

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN

RETURN QUERY EXECUTE '
WITH v_tb_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;

END     
$$ LANGUAGE plpgsql;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

• You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

• The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work

• I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.

Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)

The query itself seems rather odd, btw. But that's beside the point here.

This works and gives you the installed at path for each gem. This super helpful when trying to do multi-stage docker builds.. You can copy in the specific directory post-bundle install.

Segmentation fault is a generic one, there are many possible reasons for this:

• Low memory
• Faulty Ram memory
• Fetching a huge data set from the db using a query (if the size of fetched data is more than swap mem)
• wrong query / buggy code
• having long loop (multiple recursion)

From Python 3.0 changelog;

The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively.

From the Python 3 email documentation it can be seen that io.StringIO should be used instead:

from io import StringIO
from email.generator import Generator
fp = StringIO()
g = Generator(fp, mangle_from_=True, maxheaderlen=60)
g.flatten(msg)
text = fp.getvalue()

There is another way of enabling this,

1. use hadoop hdfs -copyFromLocal to copy the .csv data file from your local computer to somewhere in HDFS, say '/path/filename'

2. enter Hive console, run the following script to load from the file to make it as a Hive table. Note that '\054' is the ascii code of 'comma' in octal number, representing fields delimiter.

CREATE EXTERNAL TABLE table name (foo INT, bar STRING)
 COMMENT 'from csv file'

response.setContentType("text/html;charset=UTF-8");

• The response's character encoding is only set from the given content type if this method is called before getWriter is called.

• This method may be called repeatedly to change content type and character encoding.

• This method has no effect if called after the response has been committed. It does not set the response's character encoding if it is called after getWriter has been called or after the response has been committed.

• Containers must communicate the content type and the character encoding used for the servlet response's writer to the client if the protocol provides a way for doing so. In the case of HTTP, the Content-Type header is used.

You don't have to use Calendar. You can just play with timestamps :

Date d = initDate();//intialize your date to any date 
Date dateBefore = new Date(d.getTime() - n * 24 * 3600 * 1000 l ); //Subtract n days   

UPDATE DO NOT FORGET TO ADD "l" for long by the end of 1000.

Please consider the below WARNING:

Adding 1000*60*60*24 milliseconds to a java date will once in a great while add zero days or two days to the original date in the circumstances of leap seconds, daylight savings time and the like. If you need to be 100% certain only one day is added, this solution is not the one to use.

there's also ndisasm, which has some quirks, but can be more useful if you use nasm. I agree with Michael Mrozek that objdump is probably best.

[later] you might also want to check out Albert van der Horst's ciasdis: http://home.hccnet.nl/a.w.m.van.der.horst/forthassembler.html. it can be hard to understand, but has some interesting features you won't likely find anywhere else.

I use this:

import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.io.InputStream;

public class IconImageUtilities
{
    public static void setIconImage(Window window)
    {
        try
        {
            InputStream imageInputStream = window.getClass().getResourceAsStream("/Icon.png");
            BufferedImage bufferedImage = ImageIO.read(imageInputStream);
            window.setIconImage(bufferedImage);
        } catch (IOException exception)
        {
            exception.printStackTrace();
        }
    }
}

Just place your image called Icon.png in the resources folder and call the above method with itself as parameter inside a class extending a class from the Window family such as JFrame or JDialog:

IconImageUtilities.setIconImage(this);

A quick and easy way is to use jQuery and do this:

var $eles = $(":input[name^='q1_']").css("color","yellow");

That will grab all elements whose name attribute starts with 'q1_'. To convert the resulting collection of jQuery objects to a DOM collection, do this:

var DOMeles = $eles.get();

see http://api.jquery.com/attribute-starts-with-selector/

In pure DOM, you could use getElementsByTagName to grab all input elements, and loop through the resulting array. Elements with name starting with 'q1_' get pushed to another array:

var eles = [];
var inputs = document.getElementsByTagName("input");
for(var i = 0; i < inputs.length; i++) {
    if(inputs[i].name.indexOf('q1_') == 0) {
        eles.push(inputs[i]);
    }
}

I know that this question has been asked for a long time but as of today one simple answer is:

<img src="image.png" style="width: 55vw; min-width: 330px;" />

The use of vw in here tells that the width is relative to 55% of the width of the viewport.

All the major browsers nowadays support this.

Check this link.

If you want a true validator that does not rely on jquery and handles server side validation as well ( and you should. server side validation is the most important part) then here is a control

public class RequiredCheckBoxValidator : System.Web.UI.WebControls.BaseValidator
{
    private System.Web.UI.WebControls.CheckBox _ctrlToValidate = null;
    protected System.Web.UI.WebControls.CheckBox CheckBoxToValidate
    {
        get
        {
            if (_ctrlToValidate == null)
                _ctrlToValidate = FindControl(this.ControlToValidate) as System.Web.UI.WebControls.CheckBox;

            return _ctrlToValidate;
        }
    }

    protected override bool ControlPropertiesValid()
    {
        if (this.ControlToValidate.Length == 0)
            throw new System.Web.HttpException(string.Format("The ControlToValidate property of '{0}' is required.", this.ID));

        if (this.CheckBoxToValidate == null)
            throw new System.Web.HttpException(string.Format("This control can only validate CheckBox."));

        return true;
    }

    protected override bool EvaluateIsValid()
    {
        return CheckBoxToValidate.Checked;
    }

    protected override void OnPreRender(EventArgs e)
    {
        base.OnPreRender(e);

        if (this.Visible && this.Enabled)
        {
            System.Web.UI.ClientScriptManager cs = this.Page.ClientScript;
            if (this.DetermineRenderUplevel() && this.EnableClientScript)
            {
                cs.RegisterExpandoAttribute(this.ClientID, "evaluationfunction", "cb_verify", false);
            }
            if (!this.Page.ClientScript.IsClientScriptBlockRegistered(this.GetType().FullName))
            {
                cs.RegisterClientScriptBlock(this.GetType(), this.GetType().FullName, GetClientSideScript());
            } 
        }
    }

    private string GetClientSideScript()
    {
        return @"<script language=""javascript"">function cb_verify(sender) {var cntrl = document.getElementById(sender.controltovalidate);return cntrl.checked;}</script>";
    }
}

If the file is local as your comment about SITE_PATH suggest, it's pretty simple just execute the script and cache the result in a variable using the output control functions :

function print_xml_data_file()
{
    include(XML_DATA_FILE_DIRECTORY . 'cms/data.php');
}

function get_xml_data()
{
    ob_start();
    print_xml_data_file();
    $xml_file = ob_get_contents();
    ob_end_clean();
    return $xml_file;
}

If it's remote as lot of others said curl is the way to go. If it isn't present try socket_create or fsockopen. If nothing work... change your hosting provider.

Perhaps:

> data.frame(aname=NA, bname=NA)[numeric(0), ]
[1] aname bname
<0 rows> (or 0-length row.names)

I had the same issue in Windows

and it worked since my proxy configuration in settings.xml file was changed

So locate and edit the file inside the \conf folder, for example : C:\Program Files\apache-maven-3.2.5\conf

<proxies>
    <!-- proxy
     | Specification for one proxy, to be used in connecting to the network.
     |
    <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>jorgesys</username>
      <password>supercalifragilisticoespialidoso</password>
      <host>proxyjorgesys</host>
      <port>8080</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
    -->
  </proxies>

• In my case i had to chage from port 80 to 8080
• If you can´t edit this file that is located inside /program files you can make a copy, edit the file and replace the file located into /program files folder.

This works perfectly and this is official html5.

<object data="https://link-to-pdf"></object>

if you are using fix height div than you can use padding-top according your design need. or you can use top:50%. if we are using div than vertical align does not work so we use padding top or position according need.

The problem is mostly due to a MySQL service that is not running, so make sure it is. If it isn't, run this CMD with administrator privilege in order to start it:

sc start [Your MySQL Service name]

Try using putting the ASCII character for the dash in between the digit separations.

from this: -

to this: –

ex: change 555-555-5555 => 555–555–5555

I know I am very late, but I want to give contribution too. This error is really strange, because the browser is not able to understand how the changes should be rendered because the classes and their properties might have changed but not committed to the database.

So do one thing,

create one migration in Package Manager Console(Tools > NuGet Package Manager > Package Manager Console) using this command:

add-migration UpdateMigration

where UpdateMigration is the name of your Migration. You can give it any name of your choice but please be specific.

After that, we just need to update the database, so run this:

update-database

Now that you have committed your changes to the database, just refresh your browser and there you go!

Hope this helps.

I was looking for the same answer to this question and after much head scratching this is the answer I came up with:

#Python 3.4.3 with Pygame
import pygame

pygame.init()
pygame.display.set_caption('Crash!')
window = pygame.display.set_mode((300, 300))


# Draw Once
Rectplace = pygame.draw.rect(window, (255, 0, 0),(100, 100, 100, 100))
pygame.display.update()
# Main Loop
while True:
    # Mouse position and button clicking.
    pos = pygame.mouse.get_pos()
    pressed1, pressed2, pressed3 = pygame.mouse.get_pressed()
    # Check if the rect collided with the mouse pos
    # and if the left mouse button was pressed.
    if Rectplace.collidepoint(pos) and pressed1:
        print("You have opened a chest!")
    # Quit pygame.
            for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit(1)

something like

  List<FancyObject> theList = … ;
  Collections.sort (theList,
                    new Comparator<FancyObject> ()
                    { int compare (final FancyObject a, final FancyObject d)
                          { return (a.getName().compareTo(d.getName())); }});

If you want your script to return values, just do return [1,2,3] from a function wrapping your code but then you'd have to import your script from another script to even have any use for that information:

Return values (from a wrapping-function)

(again, this would have to be run by a separate Python script and be imported in order to even do any good):

import ...
def main():
    # calculate stuff
    return [1,2,3]

Exit codes as indicators

(This is generally just good for when you want to indicate to a governor what went wrong or simply the number of bugs/rows counted or w/e. Normally 0 is a good exit and >=1 is a bad exit but you could inter-prate them in any way you want to get data out of it)

import sys
# calculate and stuff
sys.exit(100)

And exit with a specific exit code depending on what you want that to tell your governor. I used exit codes when running script by a scheduling and monitoring environment to indicate what has happened.

(os._exit(100) also works, and is a bit more forceful)

Stdout as your relay

If not you'd have to use stdout to communicate with the outside world (like you've described). But that's generally a bad idea unless it's a parser executing your script and can catch whatever it is you're reporting to.

import sys
# calculate stuff
sys.stdout.write('Bugs: 5|Other: 10\n')
sys.stdout.flush()
sys.exit(0)

Are you running your script in a controlled scheduling environment then exit codes are the best way to go.

Files as conveyors

There's also the option to simply write information to a file, and store the result there.

# calculate
with open('finish.txt', 'wb') as fh:
    fh.write(str(5)+'\n')

And pick up the value/result from there. You could even do it in a CSV format for others to read simplistically.

Sockets as conveyors

If none of the above work, you can also use network sockets locally *(unix sockets is a great way on nix systems). These are a bit more intricate and deserve their own post/answer. But editing to add it here as it's a good option to communicate between processes. Especially if they should run multiple tasks and return values.

"Is there a good way to handle this problem?" No. Nothing can be protected against reverse engineering. Even the firmware on DVD machines has been reverse engineered and the AACS Encryption key exposed. And that's in spite of the DMCA making that a criminal offense.

Since no technical method can stop your customers from reading your code, you have to apply ordinary commercial methods.

1. Licenses. Contracts. Terms and Conditions. This still works even when people can read the code. Note that some of your Python-based components may require that you pay fees before you sell software using those components. Also, some open-source licenses prohibit you from concealing the source or origins of that component.

2. Offer significant value. If your stuff is so good -- at a price that is hard to refuse -- there's no incentive to waste time and money reverse engineering anything. Reverse engineering is expensive. Make your product slightly less expensive.

3. Offer upgrades and enhancements that make any reverse engineering a bad idea. When the next release breaks their reverse engineering, there's no point. This can be carried to absurd extremes, but you should offer new features that make the next release more valuable than reverse engineering.

4. Offer customization at rates so attractive that they'd rather pay you to build and support the enhancements.

5. Use a license key which expires. This is cruel, and will give you a bad reputation, but it certainly makes your software stop working.

6. Offer it as a web service. SaaS involves no downloads to customers.

before you do other way, please do open php.exe on your PHP folder. run it and if you faced any error statement on it, you can fix it manually. else, do most-usefull post in this thread.

You can create CSV file using encoding UTF8 + BOM (https://en.wikipedia.org/wiki/Byte_order_mark).

First three bytes are BOM (0xEF,0xBB,0xBF) and then UTF8 content.

You can use this function (I found it here: http://excelribbon.tips.net/T010780_Colors_in_an_IF_Function.html):

Function GetFillColor(Rng As Range) As Long
    GetFillColor = Rng.Interior.ColorIndex
End Function

Here is an explanation, how to create user-defined functions: http://www.wikihow.com/Create-a-User-Defined-Function-in-Microsoft-Excel

In your worksheet, you can use the following: =GetFillColor(B5)

If you need a function that behaves as a nop, try

nop = lambda *a, **k: None
nop()

Sometimes I do stuff like this when I'm making dependencies optional:

try:
    import foo
    bar=foo.bar
    baz=foo.baz
except:
    bar=nop
    baz=nop

# Doesn't break when foo is missing:
bar()
baz()

I found that in my code when I used a ration or percentage for line-height line-height;1.5;

My page would scale in such a way that lower case font and upper case font would take up different page heights (I.E. All caps took more room than all lower). Normally I think this looks better, but I had to go to a fixed height line-height:24px; so that I could predict exactly how many pixels each page would take with a given number of lines.

Yes, this is a current issue in Chrome. There is an issue report here.

The fix will appear in 40.x.y.z versions.

Until then? I don't think you can resolve the issue yourself. But you can ignore it. The shown error is only related to the dev tools and does not influence the behavior of your website. If you have any other problems they are not related to this error.

Both do the same work as they are used for routing purposes in SPA(Single Page Application).

1. Angular Routing - per $routeProvider docs

URLs to controllers and views (HTML partials). It watches $location.url() and tries to map the path to an existing route definition.

HTML

<div ng-view></div>

Above tag will render the template from the $routeProvider.when() condition which you had mentioned in .config (configuration phase) of angular

Limitations:-

• The page can only contain single ng-view on page
• If your SPA has multiple small components on the page that you wanted to render based on some conditions, $routeProvider fails. (to achieve that, we need to use directives like ng-include, ng-switch, ng-if, ng-show, which looks bad to have them in SPA)
• You can not relate between two routes like parent and child relationship.
• You cannot show and hide a part of the view based on url pattern.

2. ui-router - per $stateProvider docs

AngularUI Router is a routing framework for AngularJS, which allows you to organize the parts of your interface into a state machine. UI-Router is organized around states, which may optionally have routes, as well as other behavior, attached.

Multiple & Named Views

Another great feature is the ability to have multiple ui-views in a template.

While multiple parallel views are a powerful feature, you'll often be able to manage your interfaces more effectively by nesting your views, and pairing those views with nested states.

HTML

<div ui-view>
    <div ui-view='header'></div>
    <div ui-view='content'></div>
    <div ui-view='footer'></div>
</div>

The majority of ui-router's power is it can manage nested state & views.

Pros

• You can have multiple ui-view on single page
• Various views can be nested in each other and maintained by defining state in routing phase.
• We can have child & parent relationship here, simply like inheritance in state, also you could define sibling states.
• You could change the ui-view="some" of state just by using absolute routing using @ with state name.
• Another way you could do relative routing is by using only @ to change ui-view="some". This will replace the ui-view rather than checking if it is nested or not.
• Here you could use ui-sref to create a href URL dynamically on the basis of URL mentioned in a state, also you could give a state params in the json format.

For more Information Angular ui-router

For better flexibility with various nested view with states, I'd prefer you to go for ui-router

Both the match() (returns the first appearance) and %in% (returns a Boolean) functions are designed for this.

v <- c('a','b','c','e')

'b' %in% v
## returns TRUE

match('b',v)
## returns the first location of 'b', in this case: 2

If they're contiguous, you can just do

x[2:6] = []

If you want to remove noncontiguous indexes, it's a little trickier.

x = [v for i,v in enumerate(x) if i not in frozenset((2,3,4,5))] 

For the arrow color, you can use this:

.tooltip .tooltip-arrow {border-top: 5px solid red !important;}

All good answers...From the validation perspective, I also noticed that MaxLength gets validated at the server side only, while StringLength gets validated at client side too.

Just a friendly reminder if you have files locally that aren't in github and yet your git status says

Your branch is up to date with 'origin/master'. nothing to commit, working tree clean

It can happen if the files are in .gitignore

Try running

cat .gitignore 

and seeing if these files show up there. That would explain why git doesn't want to move them to the remote.

In your ASP.NET page:

<asp:Label ID="UserNameLabel" runat="server" />

In your code behind (assuming you're using C#):

function Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
       UserNameLabel.Text = "User Name";
    }
}

One thing we should note: the jdk should be installed on C: drive.

I had JDK installed on my D: drive like this:

D:\Program Files\Java\jdk1.8.0_101

And it would still give me the same error. For some reason Java should be installed on C: drive.

Check whether you have matching IDs in both Java and XML

it should be :

$_SERVER['REQUEST_URI'];

Take a look at : Get the full URL in PHP

If you use Spring frameworks, then you can use CollectionUtils to check against both Collections (List, Array) and Map etc.

if(CollectionUtils.isEmpty(...)) {...}

Here are the detailed steps needed to achieve this.

The existing commands can be simply run via the CLI terminal of VS-CODE. It is understood that Git is installed in the system, configured with desired username and email Id.

1) Navigate to the local project directory and create a local git repository:

 git init

2) Once that is successful, click on the 'Source Control' icon on the left navbar in VS-Code.One should be able to see files ready to be commit-ed. Press on 'Commit' button, provide comments, stage the changes and commit the files. Alternatively you can run from CLI

git commit -m "Your comment"

3) Now you need to visit your GitHub account and create a new Repository. Exclude creating 'README.md', '.gitIgnore' files. Also do not add any License to the repo. Sometimes these settings cause issue while pushing in.

4) Copy the link to this newly created GitHub Repository.

5) Come back to the terminal in VS-CODE and type these commands in succession:

git remote add origin <Link to GitHub Repo>     //maps the remote repo link to local git repo

git remote -v                                  //this is to verify the link to the remote repo 

git push -u origin master                      // pushes the commit-ed changes into the remote repo

Note: If it is the first time the local git account is trying to connect to GitHub, you may be required to enter credentials to GitHub in a separate window.

6) You can see the success message in the Terminal. You can also verify by refreshing the GitHub repo online.

Hope this helps

For me this problem occurred because I had a some invalid character in my Groovy script. In our case this was an extra blank line after the closing bracket of the script.

Use DATE() function:

select * from follow_queue group by DATE(follow_date)

When you want to create a new line or wrap in your TextArea you have to add \n (newline) after the text.

TextArea t = new TextArea();
t.setText("insert text when you want a new line add \nThen more text....);
setBounds();
setFont();
add(t);

This is the only way I was able to do it, maybe there is a simpler way but I havent discovered that yet.

Update using NuGet Package Manager Console in your Visual Studio

Update-Package -reinstall Microsoft.AspNet.Mvc

Open finder>Library>Developer>CoreSimulator>Devices

Then Change Arrangement icon from finder select Date Added

Select your app >data>Container>data>Applications>

choose your app >Documents>Here is your db file

In my case:

/Users/pluto/Library/Developer/CoreSimulator/Devices/A75107D2-A535-415A-865D-978B2555370B/data/Containers/Data/Application/265A12BC-FF5B-4235-B5EF-6022B83754B4/Documents/dboPhotoBucket.sqlite

Otherwise do this :

NSLog(@"app dir: %@",[[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]); 

- It will print the full path to data folder.

Swift:

let dirPaths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
println("App Path: \(dirPaths)")

To insert the Value into the Dictionary

 Dictionary<string, string> dDS1 = new Dictionary<string, string>();//Declaration
 dDS1.Add("VEqpt", "aaaa");//adding key and value into the dictionary
 string Count = dDS1["VEqpt"];//assigning the value of dictionary key to Count variable
 dDS1["VEqpt"] = Count + "bbbb";//assigning the value to key

The simplest solution is to select the second cell, and press =. This will begin the fomula creation process. Now either type in the 1st cell reference (eg, A1) or click on the first cell and press enter. This should make the second cell reference the value of the first cell.

This depends on a lot of things, such as what is the size of the file, what is its type (text/binary) etc. Some time ago I benchmarked the following function against versions using streambuf iterators - it was about twice as fast:

unsigned int FileRead( std::istream & is, std::vector <char> & buff ) {
    is.read( &buff[0], buff.size() );
    return is.gcount();
}

void FileRead( std::ifstream & ifs, string & s ) {
    const unsigned int BUFSIZE = 64 * 1024; // reasoable sized buffer
    std::vector <char> buffer( BUFSIZE );

    while( unsigned int n = FileRead( ifs, buffer ) ) {
        s.append( &buffer[0], n );
    }
}

If you have multiple layer proxies just like CDN + Load Balancer.
Using Laravel Request::ip() function will get right-most proxy IP but not client IP.
You may try following solution.

app/Http/Middleware/TrustProxies.php

protected $proxies = ['0.0.0.0/0'];

Let me share an example which I developed with BS4, thymeleaf and Spring boot.

I am using two SELECTs, where the second ("subtopic") gets filled by an AJAX call based on the selection of the first("topic").

First, the thymeleaf snippet:

 <div class="form-group">
     <label th:for="topicId" th:text="#{label.topic}">Topic</label>
     <select class="custom-select"
             th:id="topicId" th:name="topicId"
             th:field="*{topicId}"
             th:errorclass="is-invalid" required>
         <option value="" selected
                 th:text="#{option.select}">Select
         </option>
         <optgroup th:each="topicGroup : ${topicGroups}"
                   th:label="${topicGroup}">
             <option th:each="topicItem : ${topics}"
                     th:if="${topicGroup == topicItem.grp} "
                     th:value="${{topicItem.baseIdentity.id}}"
                     th:text="${topicItem.name}"
                     th:selected="${{topicItem.baseIdentity.id==topicId}}">
             </option>
         </optgroup>
         <option th:each="topicIter : ${topics}"
                 th:if="${topicIter.grp == ''} "
                 th:value="${{topicIter.baseIdentity.id}}"
                 th:text="${topicIter.name}"
                 th:selected="${{topicIter.baseIdentity?.id==topicId}}">
         </option>
     </select>
     <small id="topicHelp" class="form-text text-muted"
            th:text="#{label.topic.tt}">select</small>

I am iterating over a list of topics that is stored in the model context, showing all groups with their topics, and after that all topics that do not have a group. BaseIdentity is an @Embedded composite key BTW.

Now, here's the jQuery that handles changes:

$('#topicId').change(function () {
    selectedOption = $(this).val();
    if (selectedOption === "") {
        $('#subtopicsId').prop('disabled', 'disabled').val('');
        $("#subtopicsId option").slice(1).remove(); // keep first
    } else {
        $('#subtopicsId').prop('disabled', false)
        var orig = $(location).attr('origin');
        var url = orig + "/getsubtopics/" + selectedOption;
        $.ajax({
            url: url,
           success: function (response) {
                  var len = response.length;
                    $("#subtopicsId option[value!='']").remove(); // keep first 
                    for (var i = 0; i < len; i++) {
                        var id = response[i]['baseIdentity']['id'];
                        var name = response[i]['name'];
                        $("#subtopicsId").append("<option value='" + id + "'>" + name + "</option>");
                    }
                },
                error: function (e) {
                    console.log("ERROR : ", e);
                }
        });
    }
}).change(); // and call it once defined

The initial call of change() makes sure it will be executed on page re-load or if a value has been preselected by some initialization in the backend.

BTW: I am using "manual" form validation (see "is-valid"/"is-invalid"), because I (and users) didn't like that BS4 marks non-required empty fields as green. But that's byond scope of this Q and if you are interested then I can post it also.

Latin-1 (aka ISO 8859-1) is a single octet character encoding scheme, and you can't fit \u201c (“) into a byte.

Did you mean to use UTF-8 encoding?

You can put dimens.xml in

1) values

2) values-hdpi

3) values-xhdpi

4) values-xxhdpi

And give different sizes in dimens.xml within corresponding folders according to densities.

I know that this is an old question, but I have not seen any answers to this effect: Essentially, if you are using markdown and pandoc to convert your file to pdf, in your yaml data at the top of the page, you can include something like this:

---
header-includes:
- \usepackage{pdfpages}
output: pdf_document
---

\includepdf{/path/to/pdf/document.pdf}

# Section

Blah blah

## Section 

Blah blah

Since pandoc using latex to convert all of your documents, the header-includes section calls the pdfpages package. Then when you include \includepdf{/path/to/pdf/document.pdf} it will insert whatever is include in that document. Furthermore, you can include multiple pdf files this way.

As a fun bonus, and this is only because I often use markdown, if you would like to include files other than markdown, for instance latex files. I have modified this answer somewhat. Say that you have a markdown file markdown1.md:

---
title: Something meaning full
author: Talking head
---

And two addtional latex file document1, that looks like this:

\section{Section}

Profundity.

\subsection{Section}

Razor's edge.

And another, document2.tex, that looks like this:

\section{Section

Glah

\subsection{Section}

Balh Balh

Assuming that you want to include document1.tex and document2.tex into markdown1.md, you would just do this to markdown1.md

---
title: Something meaning full
author: Talking head
---

\input{/path/to/document1}
\input{/path/to/document2}

Run pandoc over it, e.g.

in terminal pandoc markdown1.md -o markdown1.pdf

Your final document will look somewhat like this:

Something Meaning Full

Talking Head

Section

Profundity.

Section

Razor's edge.

The for loop is definitely more pythonic, as it uses Python's higher level built in functionality to convey what you're doing both more clearly and concisely. The overhead of range vs xrange, and assigning an unused i variable, stem from the absence of a statement like Verilog's repeat statement. The main reason to stick to the for range solution is that other ways are more complex. For instance:

from itertools import repeat

for unused in repeat(None, 10):
    del unused   # redundant and inefficient, the name is clear enough
    print "This is run 10 times"

Using repeat instead of range here is less clear because it's not as well known a function, and more complex because you need to import it. The main style guides if you need a reference are PEP 20 - The Zen of Python and PEP 8 - Style Guide for Python Code.

We also note that the for range version is an explicit example used in both the language reference and tutorial, although in that case the value is used. It does mean the form is bound to be more familiar than the while expansion of a C-style for loop.

The Union command is what you need. If that doesn't work, you may need to refine what environment you are in.

In addition to answer of @jww, I would like to say that the configuration in openssl-ca.cnf,

default_days     = 1000         # How long to certify for

defines the default number of days the certificate signed by this root-ca will be valid. To set the validity of root-ca itself you should use '-days n' option in:

openssl req -x509 -days 3000 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM

Failing to do so, your root-ca will be valid for only the default one month and any certificate signed by this root CA will also have validity of one month.

Without jQuery:

You don't need jQuery when it is so simple to do this using pure JavaScript. Here are two options:

• Method 1 - Retrieve the exact value of the href attribute:

  Select the element and then use the .getAttribute() method.

  This method does not return the full URL, instead it retrieves the exact value of the href attribute.

  _x000D_

  _x000D_

  var anchor = document.querySelector('a'),_x000D_
      url = anchor.getAttribute('href');_x000D_
  _x000D_
  alert(url);

  _x000D_

  <a href="/relative/path.html"></a>

  _x000D_

  _x000D_
  _x000D_

• Method 2 - Retrieve the full URL path:

  Select the element and then simply access the href property.

  This method returns the full URL path.

  In this case: http://stacksnippets.net/relative/path.html.

  _x000D_

  _x000D_

  var anchor = document.querySelector('a'),_x000D_
      url = anchor.href;_x000D_
  _x000D_
  alert(url);

  _x000D_

  <a href="/relative/path.html"></a>

  _x000D_

  _x000D_
  _x000D_

As your title implies, you want to get the href value on click. Simply select an element, add a click event listener and then return the href value using either of the aforementioned methods.

var anchor = document.querySelector('a'),_x000D_
    button = document.getElementById('getURL'),_x000D_
    url = anchor.href;_x000D_
_x000D_
button.addEventListener('click', function (e) {_x000D_
  alert(url);_x000D_
});

<button id="getURL">Click me!</button>_x000D_
<a href="/relative/path.html"></a>

"==" always compare the memory location or object references of the values. equals method always compare the values. But equals also indirectly uses the "==" operator to compare the values.

Integer uses Integer cache to store the values from -128 to +127. If == operator is used to check for any values between -128 to 127 then it returns true. for other than these values it returns false .

Refer the link for some additional info

Use Add/Remove programs from the Control Panel.

Use operator overloading feature of java

class Test {

    void printType(String x) {
        System.out.print("String");
    }

    void printType(int x) {     
        System.out.print("Int");
    }

    // same goes on with boolean,double,float,object ...

}

This also works for https needed a solution to making project directories this was it. because chrome doesn't like non ssl anymore used free ssl. Notice: My Web Server is Wamp64 on Windows 10 so I wouldn't use this config because of variables unless your using wamp.

declare @starttime datetime = '2012-03-07 22:58:00'

SELECT BookingId, StartTime

WHERE ABS( DATEDIFF( minute, StartTime, @starttime ) ) <= 60

The following works perfectly! I just used it, try it out.

date_format(date,'%Y-%c')

You cannot set height and width for elements with display:inline;. Use display:inline-block; instead.

From the CSS2 spec:

10.6.1 Inline, non-replaced elements

The height property does not apply. The height of the content area should be based on the font, but this specification does not specify how. A UA may, e.g., use the em-box or the maximum ascender and descender of the font. (The latter would ensure that glyphs with parts above or below the em-box still fall within the content area, but leads to differently sized boxes for different fonts; the former would ensure authors can control background styling relative to the 'line-height', but leads to glyphs painting outside their content area.)

EDIT — You're also missing a ; terminator for the height property:

<div style="display:inline; height:20px width: 70px">My Text Here</div>
<!--                                  ^^ here                       -->

You have not specified the schema location of the context namespace, that is the reason for this specific error:

According to a slideshow about Facebook's Messaging system, Facebook uses the comet technology to "push" message to web browsers. Facebook's comet server is built on the open sourced Erlang web server mochiweb.

In the picture below, the phrase "channel clusters" means "comet servers".

Many other big web sites build their own comet server, because there are differences between every company's need. But build your own comet server on a open source comet server is a good approach.

You can try icomet, a C1000K C++ comet server built with libevent. icomet also provides a JavaScript library, it is easy to use as simple as:

var comet = new iComet({
    sign_url: 'http://' + app_host + '/sign?obj=' + obj,
    sub_url: 'http://' + icomet_host + '/sub',
    callback: function(msg){
        // on server push
        alert(msg.content);
    }
});

icomet supports a wide range of Browsers and OSes, including Safari(iOS, Mac), IEs(Windows), Firefox, Chrome, etc.

my.data.frame <- subset(data , V1 > 2 | V2 < 4)

An alternative solution that mimics the behavior of this function and would be more appropriate for inclusion within a function body:

new.data <- data[ which( data$V1 > 2 | data$V2 < 4) , ]

Some people criticize the use of which as not needed, but it does prevent the NA values from throwing back unwanted results. The equivalent (.i.e not returning NA-rows for any NA's in V1 or V2) to the two options demonstrated above without the which would be:

 new.data <- data[ !is.na(data$V1 | data$V2) & ( data$V1 > 2 | data$V2 < 4)  , ]

Note: I want to thank the anonymous contributor that attempted to fix the error in the code immediately above, a fix that got rejected by the moderators. There was actually an additional error that I noticed when I was correcting the first one. The conditional clause that checks for NA values needs to be first if it is to be handled as I intended, since ...

> NA & 1
[1] NA
> 0 & NA
[1] FALSE

Order of arguments may matter when using '&".

It is possible on your restart some shards were not recovered, causing the cluster to stay red.
If you hit:
http://<yourhost>:9200/_cluster/health/?level=shards you can look for red shards.

I have had issues on restart where shards end up in a non recoverable state. My solution was to simply delete that index completely. That is not an ideal solution for everyone.

It is also nice to visualize issues like this with a plugin like:
Elasticsearch Head

In April 2017 a patch was merged into Safari, so it aligned with the other browsers. This was released with Safari 11.
