Since there is only one WiFi hardware on the computer its not possible to connect one WiFi hardware to multiple WiFi networks, if you want to that I think you have to map WiFi hardware to guest OS and how host you'll have to use some other hardware (may be Ethernet) but I'm sure that it will work in that way as no VM software allow us to allocate Hardware to Guest except for USB, you can also get USB WiFI and allocate that to VM only.

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

Fix Step by step:

If you not have vbguest plugin, install it:

$ vagrant plugin install vagrant-vbguest

Run Vagrant

It is show a error.

$ vagrant up

Login on VM

$ vagrant ssh

Fix!

In the guest (VM logged).

$ sudo ln -s /opt/VBoxGuestAdditions-4.3.10/lib/VBoxGuestAdditions /usr/lib/VBoxGuestAdditions

Back on the host, reload Vagrant

$ vagrant reload

based on swift:

let alertCtr = UIAlertController(title:"Title", message:"Message", preferredStyle: .Alert)
let Cancel = AlertAction(title:"remove", style: .Default, handler: {(UIAlertAction) -> Void in })
let Remove = UIAlertAction(title:"remove", style: .Destructive, handler:{(UIAlertAction)-> Void 
    inself.colorLabel.hidden = true    
})
alertCtr.addAction(Cancel)
alertCtr.addAction(Remove)

self.presentViewController(alertCtr, animated:true, completion:nil)}

PHP runs on the server-side thus you have to use a client-side technology which is capable of showing popup windows: JavaScript.

So you should output a specific JS block via PHP if your form contains errors and you want to show that popup.

SELECT p.MEMBSHIP_ID
FROM user_payments as p
WHERE USER_ID = 1 AND PAYM_DATE = (
    SELECT MAX(p2.PAYM_DATE)
    FROM user_payments as p2
    WHERE p2.USER_ID = p.USER_ID
)

Follow this link for new updates. Use Java 8 language features

Old Answer

As of Android N preview release Android support limited features of Java 8 see Java 8 Language Features

To start using these features, you need to download and set up Android Studio 2.1 and the Android N Preview SDK, which includes the required Jack toolchain and updated Android Plugin for Gradle. If you haven't yet installed the Android N Preview SDK, see Set Up to Develop for Android N.

Supported Java 8 Language Features and APIs

Android does not currently support all Java 8 language features. However, the following features are now available when developing apps targeting the Android N Preview:

Default and static interface methods

Lambda expressions (also available on API level 23 and lower)

Repeatable annotations

Method References (also available on API level 23 and lower)

There are some additional Java 8 features which Android support, you can see complete detail from Java 8 Language Features

Update

Note: The Android N bases its implementation of lambda expressions on anonymous classes. This approach allows them to be backwards compatible and executable on earlier versions of Android. To test lambda expressions on earlier versions, remember to go to your build.gradle file, and set compileSdkVersion and targetSdkVersion to 23 or lower.

Update 2

Now Android studio 3.0 stable release support Java 8 libraries and Java 8 language features (without the Jack compiler).

Instead of only using the path to your script in the task scheduler, you should start PowerShell with your script in the task scheduler, e.g.

C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe -NoLogo -NonInteractive -File "C:\Path\To\Your\PS1File.ps1"

See powershell /? for an explanation of those switches.

If you still get problems you should read this question.

This is super simple, just use dir(object)
This will return a list of every available function and attribute of the object.

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

Your views will be much cleaner and readable as well.

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0/angular.min.js"></script>_x000D_
<div ng-app init="item = {photo: ''}">_x000D_
   <div ng-if="item.photo"> show if photo is not empty</div>_x000D_
   <div ng-if="!item.photo"> show if photo is empty</div>_x000D_
  _x000D_
   <input type=text ng-model="item.photo" placeholder="photo" />_x000D_
</div

To start your node in PST time zone , use following command in ubuntu.

TZ=\"/usr/share/zoneinfo/GMT+0\" && export TZ && npm start &

Then You can refer Date Library to get the custom calculation date and time functions in node.

To use it client side refer this link, download index.js and assertHelper.js and include that in your HTML.

<script src="assertHelper.js"></script>
<script type="text/javascript" src="index.js"></script>
$( document ).ready(function() {
    DateLibrary.getDayOfWeek(new Date("2015-06-15"),{operationType:"Day_of_Week"}); // Output : Monday
}

You can use different functions as given in examples to get custom dates.

If first day of week is Sunday, what day will be on 15th June 2015.

 DateLibrary.getDayOfWeek(new Date("2015-06-15"),
    {operationType:"Day_Number_of_Week",
        startDayOfWeek:"Sunday"}) // Output : 1

If first day of week is Tuesday, what week number in year will be follow in 15th June 2015 as one of the date.

 DateLibrary.getWeekNumber(new Date("2015-06-15"),
    {operationType:"Week_of_Year",
        startDayOfWeek:"Tuesday"}) // Output : 24

Refer other functions to fulfill your custom date requirements.

Install msys2 with make dependency add both to PATH variable. (The second option is GNU ToolChain for Windows. MinGW version has already mingw32-make included.)

Install Git Bash. Run mingw32-make from Git Bash.

After my previous answer was deleted for failing to include the code, on the basis the Ansi characters used can not be displayed by stack overflow rendering the presence of the code somewhat pointless given it was based on them, I have redesigned the code to include the method of populating the Escape character detailed by @Sam Hasler

In the process, I've also taken out all the subroutines in favor of macro's, and adapted my approach to passing parameters to the macro's.

All macro's balance the Setlocal / Endlocal pairings to prevent exceeding recursion level's through use of ^&^& endlocal after completeing their handling of the Args.

The std.out macro also demonstrates how to adapt the macros to store output into variables that survive past the Endlocal barrier.

My thanks to @Martijn Pieters for deleting my previous answer. In rewriting my code I also discovered for myself some new ways to manipulate macro's.

You will always have to iterate. Yet you can use Java 8, 9 to do the counting without looping explicitely:

Iterable<Integer> newIterable = () -> iter;
long count = StreamSupport.stream(newIterable.spliterator(), false).count();

Here is a test:

public static void main(String[] args) throws IOException {
    Iterator<Integer> iter = Arrays.asList(1, 2, 3, 4, 5).iterator();
    Iterable<Integer> newIterable = () -> iter;
    long count = StreamSupport.stream(newIterable.spliterator(), false).count();
    System.out.println(count);
}

This prints:

5

Interesting enough you can parallelize the count operation here by changing the parallel flag on this call:

long count = StreamSupport.stream(newIterable.spliterator(), *true*).count();

If you used read.table() (or one of it's ilk, e.g. read.csv()) then the easy fix is to change the call to:

read.table(file = "foo.txt", row.names = 1, ....)

where .... are the other arguments you needed/used. The row.names argument takes the column number of the data file from which to take the row names. It need not be the first column. See ?read.table for details/info.

If you already have the data in R and can't be bothered to re-read it, or it came from another route, just set the rownames attribute and remove the first variable from the object (assuming obj is your object)

rownames(obj) <- obj[, 1]  ## set rownames
obj <- obj[, -1]           ## remove the first variable

Kill all applications related to java in task manager and then delete the Java.exe , Javaw.exe and Jawaws.exe from C:\windows\System32

This should solve your problem... :)

Well here is a solution for you but I don't really understand why it works:

<html><body>
  <div style="width: 200px; border: 1px solid red;">Test</div>
  <div style="width: 200px; border: 1px solid blue; overflow: hidden; height: 1.5em;">My hovercraft is full of eels.  These pretzels are making me thirsty.</div>
  <div style="width: 200px; border: 1px solid yellow; overflow: hidden; height: 1.5em;">
  This_is_a_terrible_example_of_thinking_outside_the_box.
  </div>
  <table style="border: 2px solid black; border-collapse: collapse; width: 200px;"><tr>
   <td style="width:200px; border: 1px solid green; overflow: hidden; height: 1.5em;"><div style="width: 200px; border: 1px solid yellow; overflow: hidden;">
    This_is_a_terrible_example_of_thinking_outside_the_box.
   </div></td>
  </tr></table>
</body></html>

Namely, wrapping the cell contents in a div.

You use the -classpath argument. You can use either a relative or absolute path. What that means is you can use a path relative to your current directory, OR you can use an absolute path that starts at the root /.

Example:

bash$ java -classpath path/to/jar/file MyMainClass

In this example the main function is located in MyMainClass and would be included somewhere in the jar file.

For compiling you need to use javac

Example:

bash$ javac -classpath path/to/jar/file MyMainClass.java

You can also specify the classpath via the environment variable, follow this example:

bash$ export CLASSPATH="path/to/jar/file:path/tojar/file2"
bash$ javac MyMainClass.java

For any normally complex java project you should look for the ant script named build.xml

int? is shorthand for Nullable<int>.

This may be the post you were looking for.

I created a package called json-dry. It supports (circular) references and also class instances.

You have to define 2 new methods in your class (toDry on the prototype and unDry as a static method), register the class (Dry.registerClass), and off you go.

You can just display both the text and image as inline-blocks so that they dont stack. using floats like pull-left/pull-right can cause undesired issues so they should be used sparingly

<a class="navbar-brand" href="#">
  <img src="mylogo.png" style="display: inline-block;">
  <span style="display: inline-block;">My Company</span>
</a>

If you want to detach existing object follow @Slauma's advice. If you want to load objects without tracking changes use:

var data = context.MyEntities.AsNoTracking().Where(...).ToList();

As mentioned in comment this will not completely detach entities. They are still attached and lazy loading works but entities are not tracked. This should be used for example if you want to load entity only to read data and you don't plan to modify them.

One obvious thing is that you will have to remove the comma here

receipt int(10),

but the actual problem is because of the line

amount double(10) NOT NULL,

change it to

amount double NOT NULL,

In my case, problem was due to low disk space. I want to mention it for other users like me :)

I had an identical problem with the same error message but the solution with removal of unused docker networks didn't help me. I've deleted all non-default docker networks (and all images and containers as well) but it didn't help - docker still was not able to create a new network.

The cause of the problem was in network interfaces that were left after OpenVpn installation. (It was installed on the host previously.) I found them by running ifconfig command:

...

...

I've found that I can remove them with a couple of commands:

ip link delete tun0
ip link delete tun1

After this the problem has disappeared.

As an alternative to @Mark Byers' approach, you can use while True:

guess = 50     # this should be outside the loop, I think
while True:    # infinite loop
    n = raw_input("\n\nTrue, False or Correct?: ")
    if n == "Correct":
        break  # stops the loop
    elif n == "True":
        # etc.

Aergistal's answer works, but I found that converting to mp4 can make some m3u8 videos broken. If you are stuck with this problem, try to convert them to mkv, and convert them to mp4 later.

Trick to update props if they are array :

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  Button
} from 'react-native';

class Counter extends Component {
  constructor(props) {
    super(props);
      this.state = {
        count: this.props.count
      }
    }
  increment(){
    console.log("this.props.count");
    console.log(this.props.count);
    let count = this.state.count
    count.push("new element");
    this.setState({ count: count})
  }
  render() {

    return (
      <View style={styles.container}>
        <Text>{ this.state.count.length }</Text>
        <Button
          onPress={this.increment.bind(this)}
          title={ "Increase" }
        />
      </View>
    );
  }
}

Counter.defaultProps = {
 count: []
}

export default Counter
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
});

In your component

let today: string;

ngOnInit() {
  this.today = new Date().toISOString().split('T')[0];
}

and in your html file

<input name="date" [(ngModel)]="today" type="date" required>

As almost anyone said, adding a runtime service will solve the problem. But if there is no runtime services or there is something like Google App Engine which is not your favorite any how, click New button right down the Targeted Runtimes list and add a new runtime server environment. Then check it and click OK and let the compiler to compile your project again.

Hope it helps ;)

Imagine that this is your Json response

{"Visit":{"VisitId":8,"Description":"visit8"}}

This is how you parse the response and access the values

    Ext.Ajax.request({
    headers: {
        'Content-Type': 'application/json'
    },
    url: 'api/fullvisit/getfullvisit/' + visitId,
    method: 'GET',
    dataType: 'json',
    success: function (response, request) {
        obj = JSON.parse(response.responseText);
        alert(obj.Visit.VisitId);
    }
});

This will alert the VisitId field

Adding to joquin's answer the following form might be a bit cleaner (at least nicer to read):

x = p.Series()
N = 4
for i in xrange(N):
   x[i] = i**2

which would produce the same output

also, a bit less orthodox but if you wanted to simply add a single element to the end:

x=p.Series()
value_to_append=5
x[len(x)]=value_to_append

The problem is an issue of semantic meaning (as BoltClock mentions) and visual rendering.

Originally HTML used <b> and <i> for these purposes, entirely stylistic commands, laid down in the semantic environment of the document markup. CSS is an attempt to separate out as far as possible the stylistic elements of the medium. Thus style information such as bold and italics should go in CSS.

<strong> and <em> were introduced to fill the semantic need for text to be marked as more important or stressed. They have default stylistic interpretations akin to bold and italic, but they are not bound to that fate.

Here is another way

$( '#iframe' ).attr( 'src', function () { return $( this )[0].src; } );

You need an Oracle Client: http://www.oracle.com/technology/oramag/oracle/08-nov/o68odpnet.html

You cannot use a select statement that assigns values to variables to also return data to the user The below code will work fine, because i have declared 1 local variable and that variable is used in select statement.

 Begin
    DECLARE @name nvarchar(max)
    select @name=PolicyHolderName from Table
    select @name
    END

The below code will throw error "A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations" Because we are retriving data(PolicyHolderAddress) from table, but error says data-retrieval operation is not allowed when you use some local variable as part of select statement.

 Begin
    DECLARE @name nvarchar(max)
    select 
       @name = PolicyHolderName,
       PolicyHolderAddress 
    from Table
 END

The the above code can be corrected like below,

Begin
    DECLARE @name nvarchar(max)
    DECLARE @address varchar(100)
    select 
       @name = PolicyHolderName,
       @address = PolicyHolderAddress 
    from Table
END

So either remove the data-retrieval operation or add extra local variable. This will resolve the error.

I suspect that this occurs after an attempt to undeploy your app. Do you ever kill off that thread that you've initialised during the init() process ? I would do this in the corresponding destroy() method.

Using this function you can get Image Bitmap. Just pass image url

 public Bitmap getBitmapFromURL(String strURL) {
      try {
        URL url = new URL(strURL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
      } catch (IOException e) {
        e.printStackTrace();
        return null;
      }
 }

My issue was resolved After adding
sessionFactory.setPackagesToScan( new String[] { "com.springhibernate.model" }); Tested this Functionality in spring boot latest version 2.1.2.

Full Method:

 @Bean( name="sessionFactoryConfig")
    public LocalSessionFactoryBean sessionFactoryConfig() {

        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

        sessionFactory.setDataSource(dataSourceConfig());
        sessionFactory.setPackagesToScan(
                new String[] { "com.springhibernate.model" });

        sessionFactory.setHibernateProperties(hibernatePropertiesConfig());

        return sessionFactory;
    }

Another possible solution is to completely reset the settings. This is what fixed it for me:

Tools->Import and Export settings->Reset all settings.

create a textbox:

 <TextBox Name="tb">
 ..hello..
</TextBox>

focus() ---> it is used to set input focus to the textbox control

tb.focus()

Calling object.paintComponent(g) is an error.

Instead this method is called automatically when the panel is created. The paintComponent() method can also be called explicitly by the repaint() method defined in Component class.

The effect of calling repaint() is that Swing automatically clears the graphic on the panel and executes the paintComponent method to redraw the graphics on this panel.

Strings are hard work in C.

#include <stdio.h>

int main()
{
   int i;
   char buf[12];

   for (i = 0; i < 100; i++) {
      snprintf(buf, 12, "pre_%d_suff", i); // puts string into buffer
      printf("%s\n", buf); // outputs so you can see it
   }
}

The 12 is enough bytes to store the text "pre_", the text "_suff", a string of up to two characters ("99") and the NULL terminator that goes on the end of C string buffers.

This will tell you how to use snprintf, but I suggest a good C book!

Bash does not support multidimensional arrays.

You can simulate it though by using indirect expansion:

#!/bin/bash
declare -a a0=(1 2 3 4)
declare -a a1=(5 6 7 8)
var="a1[1]"
echo ${!var}  # outputs 6

Assignments are also possible with this method:

let $var=55
echo ${a1[1]}  # outputs 55

Edit 1: To read such an array from a file, with each row on a line, and values delimited by space, use this:

idx=0
while read -a a$idx; do
    let idx++;
done </tmp/some_file

Edit 2: To declare and initialize a0..a3[0..4] to 0, you could run:

for i in {0..3}; do
    eval "declare -a a$i=( $(for j in {0..4}; do echo 0; done) )"
done

There is an answer by @hexafraction , He had specified the x and y to be top right corner which is wrong, those are top left corner .

I have also provided the source please check it.

public void setBounds(int x,
             int y,
             int width,
             int height)

Moves and resizes this component. The new location of the top-left corner is specified by x and y, and the new size is specified by width and height. This method changes layout-related information, and therefore, invalidates the component hierarchy.

Parameters:

x - the new x-coordinate of this component

y - the new y-coordinate of this component

width - the new width of this component

height - the new height of this component

source:- setBounds

the simplest way to convert a string that has a delimiter like a comma is just to use the split method

"1,2,3,4".split(',') # "1", "2", "3", "4"]

you can find more info on how to use the split method in the ruby docs

Divides str into substrings based on a delimiter, returning an array of these substrings.

If pattern is a String, then its contents are used as the delimiter when splitting str. If pattern is a single space, str is split on whitespace, with leading whitespace and runs of contiguous whitespace characters ignored.

If pattern is a Regexp, str is divided where the pattern matches. Whenever the pattern matches a zero-length string, str is split into individual characters. If pattern contains groups, the respective matches will be returned in the array as well.

If pattern is omitted, the value of $; is used. If $; is nil (which is the default), str is split on whitespace as if ` ‘ were specified.

If the limit parameter is omitted, trailing null fields are suppressed. If limit is a positive number, at most that number of fields will be returned (if limit is 1, the entire string is returned as the only entry in an array). If negative, there is no limit to the number of fields returned, and trailing null fields are not suppressed.

From C# specifications:

var f = 0f; // float
var d = 0d; // double
var m = 0m; // decimal (money)
var u = 0u; // unsigned int
var l = 0l; // long
var ul = 0ul; // unsigned long

Note that you can use an uppercase or lowercase notation.

There are a couple ways you can deal with this. First, and perhaps best, is to rework your equation so that it is not so long; it is likely unreadable if it is that long.

If it must be so, check out the AMS Short Math Guide for some ways to handle it. (on the second page)

Personally, I'd use an align environment, so that the breaking and alignment can be precisely controlled. e.g.

\begin{align*}
   x&+y+\dots+\dots+x_100000000\\
   &+x_100000001+\dots+\dots
\end{align*}

which would line up the first plus signs of each line... but obviously, you can set the alignments wherever you like.

mutil init function in one package execute order:

1. const and variable defined file init() function execute

2. init function execute order by the filename asc

Right click in Project / Clean

That always works for me

This is how I set it up:

1. Open the command prompt(CMD) as administrator.

2. Export the proxy settings :

   set http_proxy=http://username:password@proxyAddress:port

   set https_proxy=https://username:password@proxyAddress:port

3. Install the package you want to install:

   pip install PackageName

For example:

Insert \u0020 directly in the XML for a blank you would like to preserve.

<string name="spelatonertext3">-4, \u00205, \u0020\u0020-5, \u00206, \u0020-6,</string>

In the Project Navigator, select your Xcode Project file. This will show you the project settings as well as the targets in the project. Look in the "Copy Bundle Resources" Build Phase. You should find the offending files in that list twice. Delete the duplicate reference.

Xcode is complaining that you are trying to bundle the same file with your application two times.

If you're using Python3.x input will return a string,so you should use int method to convert string to integer.

Python3 Input

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.

By the way,it's a good way to use try catch if you want to convert string to int:

try:
  i = int(s)
except ValueError as err:
  pass 

Hope this helps.

What's wrong with the printStacktrace() method provided by Throwable (and thus every exception)? It shows all the info you requested, including the type, message, and stack trace of the root exception and all (nested) causes. In Java 7, it even shows you the information about "supressed" exceptions that might occur in a try-with-resources statement.

Of course you wouldn't want to write to System.err, which the no-argument version of the method does, so instead use one of the available overloads.

In particular, if you just want to get a String:

  Exception e = ...
  StringWriter sw = new StringWriter();
  e.printStackTrace(new PrintWriter(sw));
  String exceptionDetails = sw.toString();

If you happen to use the great Guava library, it provides a utility method doing this: com.google.common.base.Throwables#getStackTraceAsString(Throwable).

The order of execution is:

1. A's constructor
2. B's constructor

The assignment occurs in B's constructor after A's constructor—_super—has been called:

function B() {
    _super.apply(this, arguments);   // MyvirtualMethod called in here
    this.testString = "Test String"; // testString assigned here
}

So the following happens:

var b = new B();     // undefined
b.MyvirtualMethod(); // "Test String"

You will need to change your code to deal with this. For example, by calling this.MyvirtualMethod() in B's constructor, by creating a factory method to create the object and then execute the function, or by passing the string into A's constructor and working that out somehow... there's lots of possibilities.

I think you are simply exchanging dumps and loads.

>>> import json
>>> data = [['apple', 'cat'], ['banana', 'dog'], ['pear', 'fish']]

The first returns as a (JSON encoded) string its data argument:

>>> encoded_str = json.dumps( data )
>>> encoded_str
'[["apple", "cat"], ["banana", "dog"], ["pear", "fish"]]'

The second does the opposite, returning the data corresponding to its (JSON encoded) string argument:

>>> decoded_data = json.loads( encoded_str )
>>> decoded_data
[[u'apple', u'cat'], [u'banana', u'dog'], [u'pear', u'fish']]
>>> decoded_data == data
True

Visual Studio 2015 RC, has LocalDb 12 installed, similar instructions to before but still shouldn't be required to know 'magic', before hand to use this, the default instance should have been turned on ... Rant complete, no for solution:

cmd> sqllocaldb start

Which will display

LocalDB instance "MSSQLLocalDB" started.

Your instance name might differ. Either way pop over to VS and open Server Explorer, right click Data Connections, choose Add, choose SQL Server, in the server name type:

(localdb)\MSSQLLocalDB

Without entering in a DB name, click 'Test Connection'.

Use real two-factor authentication to avoid the sole dependency on passwords which might be stored in many more places than the user's browser cache.

Embedding a Google Drive directory in an IFRAME

Google Drive folders can be embedded and displayed in list and grid views (in which all you can do is click a file or folder to open it on a new tab). To do so, simply replace FOLDER-ID with your own in:

List view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#list" style="width:100%; height:600px; border:0;"></iframe>

or without specifying a mode, since list mode is the default:

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID" style="width:100%; height:600px; border:0;"></iframe>

Grid view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Obtaining your folder id

The id is the hash (alphanumeric gibberish) after folders/ in the URL of the folder. You can see the URL in the address bar of your browser when you open the Drive folder. For example, in:

https://drive.google.com/drive/folders/0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2 

The Folder ID is 0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2.

Folder with G Suite/Google Apps domain

If your folder is part of a Google Apps domain, you can add the domain to the URL to alleviate the permission problems (detailed further ahead):

<iframe src="https://drive.google.com/a/MY.DOMAIN.COM/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Just replace MY.DOMAIN.COM and FOLDER-ID with your own.

Caveat with folders requiring permission

This technique works best for folders with public access. Folders that are shared only with certain Google accounts can cause trouble when you embed them this way, depending on which Google accounts are active on the user's browser:

1. If the user has not logged in to any Google account, then nothing appears in the frame.
2. If the user is logged onto an account without authorisation to access the folder, the frame will contain the message You need permission, with some buttons to Request access or Switch accounts, but if you click on this last, the frame blanks out.
3. If the user logs into an account without proper permissions, and later adds the authorised account, on loading the embedded Drive Google will resort to the first active account, and the user will see You need permission, unless...
4. If the URL contains a Google Suite domain, and the user is logged into that domain's account, the embedded view will work, even if the user logged to another account first.

The blank frames are because Google forbids embedding its login page in an IFRAME (presumably to prevent account stealing), via the X-Frame-Options header, which if set to SAMEORIGIN will cause any well-behaved browser to refuse to load the page if it's not in the same domain (v.g. drive.google.com). You can see this in the developer console of your browser.

TL;DR

To get a list or grid view of a Drive folder (in which all you can do is click a file or folder to open it on a new tab), use:

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

or alternatively, for a Google Suite/Apps Drive:

<iframe src="https://drive.google.com/a/MY.DOMAIN.COM/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Replace MY.DOMAIN.COM and FOLDER-ID with your own; remove #grid to get a detailed file list.

For private folders, have your users log to the correct account before loading the page with the embedded folder; if the folder is in a Google Apps domain, you can add the domain to the URL. Else, they must log into the authorised account before any other.

(this answer is an edit of Mori's, but it was rejected as it changed his intent, somehow)

The exception is caused by disabled Download Manager. And there is no way to activate/deactivate Download Manager directly, since it's system application and we don't have access to it.

Only alternative way is redirect user to settings of Download Manager Application.

try {
     //Open the specific App Info page:
     Intent intent = new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
     intent.setData(Uri.parse("package:" + "com.android.providers.downloads"));
     startActivity(intent);

} catch ( ActivityNotFoundException e ) {
     e.printStackTrace();

     //Open the generic Apps page:
     Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_APPLICATIONS_SETTINGS);
     startActivity(intent);
}

the simplest way is

const obj = {_x000D_
  a: 'value of a',_x000D_
  b: 'value of b',_x000D_
  c: 'value of c'_x000D_
};_x000D_
_x000D_
if(obj.a){_x000D_
  console.log(obj.a);_x000D_
}else{_x000D_
  console.log('obj.a does not exist');_x000D_
}

If you use SQL authentication, use this:

using System.Data.SqlClient;

SqlConnection conn = new SqlConnection();
conn.ConnectionString = 
     "Data Source=.\SQLExpress;" + 
     "User Instance=true;" + 
     "User Id=UserName;" + 
     "Password=Secret;" + 
     "AttachDbFilename=|DataDirectory|Database1.mdf;"
conn.Open();

If you use Windows authentication, use this:

using System.Data.SqlClient;
SqlConnection conn = new SqlConnection();
conn.ConnectionString = 
     "Data Source=.\SQLExpress;" + 
     "User Instance=true;" + 
     "Integrated Security=true;" + 
     "AttachDbFilename=|DataDirectory|Database1.mdf;"
conn.Open();

Try the following:

RewriteEngine on 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?localhost [NC] 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?localhost.*$ [NC] 
RewriteRule \.(gif|jpg)$ - [F]

Returns 403, if you access images directly, but allows them to be displayed on site.

Note: It is possible that when you open some page with image and then copy that image's path into the address bar you can see that image, it is only because of the browser's cache, in fact that image has not been loaded from the server (from Davo, full comment below).

My Thought,

Implicit Wait : If wait is set, it will wait for specified amount of time for each findElement/findElements call. It will throw an exception if action is not complete.

Explicit Wait : If wait is set, it will wait and move on to next step when the provided condition becomes true else it will throw an exception after waiting for specified time. Explicit wait is applicable only once wherever specified.

Yeah, when ASP.NET web.config gets updated, the whole application gets restarted which means the web.config gets reloaded.

for (int i = 0; i < 6; i++)
{
    test.ColumnDefinitions.Add(new ColumnDefinition());

    Label t1 = new Label();
    t1.Content = "Test" + i;

    Grid.SetColumn(t1, i);
    Grid.SetRow(t1, 0);
    test.Children.Add(t1);
}

extract(hour from age(now(),links.created)) gives you a floor-rounded count of the hour difference.

As seen in https://github.com/atom/electron/issues/254 the problem is caused because of this code:

if ( typeof module === "object" && typeof module.exports === "object" ) {
  // set jQuery in `module`
} else {
  // set jQuery in `window`
}

The jQuery code "sees" that its running in a CommonJS environment and ignores window.

The solution is really easy, instead of loading jQuery through <script src="...">, you should load like this:

<script>window.$ = window.jQuery = require('./path/to/jquery');</script>

Note: the dot before the path is required, since it indicates that it's the current directory. Also, remember to load jQuery before loading any other plugin that depends on it.

Restart VS code if the NODE_ENV or any other environment variable is not providing correct value. This should work after restart.

(Edit 2016-10-12: Many Eclipse downloads from https://eclipse.org/downloads/eclipse-packages/ have M2Eclipse included already. As of Neon both the Java and the Java EE packages do - look for "Maven support")

Way 1: Maven Eclipse plugin installation step by step:

1. Open Eclipse IDE
2. Click Help -> Install New Software...
3. Click Add button at top right corner

4. At pop up: fill up Name as "M2Eclipse" and Location as "http://download.eclipse.org/technology/m2e/releases" or http://download.eclipse.org/technology/m2e/milestones/1.0

5. Now click OK

After that installation would be started.

Way 2: Another way to install Maven plug-in for Eclipse by "Eclipse Marketplace":

1. Open Eclipse
2. Go to Help -> Eclipse Marketplace
3. Search by Maven
4. Click "Install" button at "Maven Integration for Eclipse" section
5. Follow the instruction step by step

After successful installation do the followings in Eclipse:

1. Go to Window --> Preferences
   
2. Observe, Maven is enlisted at left panel

Finally,

1. Click on an existing project
2. Select Configure -> Convert to Maven Project

You can't have two Content-Types (well technically that's what we're doing below, but they are separated with each part of the multipart, but the main type is multipart). That's basically what you are expecting with your method. You are expecting mutlipart and json together as the main media type. The Employee data needs to be part of the multipart. So you can add a @FormDataParam("emp") for the Employee.

@FormDataParam("emp") Employee emp) { ...

Here's the class I used for testing

@Path("/multipart")
public class MultipartResource {
    
    @POST
    @Path("/upload2")
    @Consumes({MediaType.MULTIPART_FORM_DATA})
    public Response uploadFileWithData(
            @FormDataParam("file") InputStream fileInputStream,
            @FormDataParam("file") FormDataContentDisposition cdh,
            @FormDataParam("emp") Employee emp) throws Exception{
        
        Image img = ImageIO.read(fileInputStream);
        JOptionPane.showMessageDialog(null, new JLabel(new ImageIcon(img)));
        System.out.println(cdh.getName());
        System.out.println(emp);
        
        return Response.ok("Cool Tools!").build();
    } 
}

First I just tested with the client API to make sure it works

@Test
public void testGetIt() throws Exception {
    
    final Client client = ClientBuilder.newBuilder()
        .register(MultiPartFeature.class)
        .build();
    WebTarget t = client.target(Main.BASE_URI).path("multipart").path("upload2");

    FileDataBodyPart filePart = new FileDataBodyPart("file", 
                                             new File("stackoverflow.png"));
    // UPDATE: just tested again, and the below code is not needed.
    // It's redundant. Using the FileDataBodyPart already sets the
    // Content-Disposition information
    filePart.setContentDisposition(
            FormDataContentDisposition.name("file")
                                    .fileName("stackoverflow.png").build());

    String empPartJson
            = "{"
            + "  \"id\": 1234,"
            + "  \"name\": \"Peeskillet\""
            + "}";

    MultiPart multipartEntity = new FormDataMultiPart()
            .field("emp", empPartJson, MediaType.APPLICATION_JSON_TYPE)
            .bodyPart(filePart);
          
    Response response = t.request().post(
            Entity.entity(multipartEntity, multipartEntity.getMediaType()));
    System.out.println(response.getStatus());
    System.out.println(response.readEntity(String.class));

    response.close();
}

I just created a simple Employee class with an id and name field for testing. This works perfectly fine. It shows the image, prints the content disposition, and prints the Employee object.

I'm not too familiar with Postman, so I saved that testing for last :-)

It appears to work fine also, as you can see the response "Cool Tools". But if we look at the printed Employee data, we'll see that it's null. Which is weird because with the client API it worked fine.

If we look at the Preview window, we'll see the problem

There's no Content-Type header for the emp body part. You can see in the client API I explicitly set it

MultiPart multipartEntity = new FormDataMultiPart()
        .field("emp", empPartJson, MediaType.APPLICATION_JSON_TYPE)
        .bodyPart(filePart);

So I guess this is really only part of a full answer. Like I said, I am not familiar with Postman So I don't know how to set Content-Types for individual body parts. The image/png for the image was automatically set for me for the image part (I guess it was just determined by the file extension). If you can figure this out, then the problem should be solved. Please, if you find out how to do this, post it as an answer.

And just for completeness...

• See here for more about MultiPart with Jersey.

Basic configurations:

Dependency:

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-multipart</artifactId>
    <version>${jersey2.version}</version>
</dependency>

Client config:

final Client client = ClientBuilder.newBuilder()
    .register(MultiPartFeature.class)
    .build();

Server config:

// Create JAX-RS application.
final Application application = new ResourceConfig()
    .packages("org.glassfish.jersey.examples.multipart")
    .register(MultiPartFeature.class);

If you're having problems with the server configuration, one of the following posts might help

• What exactly is the ResourceConfig class in Jersey 2?
• 152 MULTIPART_FORM_DATA: No injection source found for a parameter of type public javax.ws.rs.core.Response

UPDATE

So as you can see from the Postman client, some clients are unable to set individual parts' Content-Type, this includes the browser, in regards to it's default capabilities when using FormData (js).

We can't expect the client to find away around this, so what we can do, is when receiving the data, explicitly set the Content-Type before deserializing. For example

@POST
@Path("upload2")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFileAndJSON(@FormDataParam("emp") FormDataBodyPart jsonPart,
                                  @FormDataParam("file") FormDataBodyPart bodyPart) { 
     jsonPart.setMediaType(MediaType.APPLICATION_JSON_TYPE);
     Employee emp = jsonPart.getValueAs(Employee.class);
}

It's a little extra work to get the POJO, but it is a better solution than forcing the client to try and find it's own solution.

Another option is to use a String parameter and use whatever JSON library you use to deserialze the String to the POJO (like Jackson ObjectMapper). With the previous option, we just let Jersey handle the deserialization, and it will use the same JSON library it uses for all the other JSON endpoints (which might be preferred).

• There is a conversation in these comments that you may be interested in if you are using a different Connector than the default HttpUrlConnection.

You can't pass a function as a parameter. Simply remove it from estimatedPopulation() and replace it with 'float growthRate'. use this in your calculation instead of calling the function:

int estimatedPopulation (int currentPopulation, float growthRate)
{
    return (currentPopulation + currentPopulation * growthRate / 100);
}

and call it as:

int foo = estimatedPopulation (currentPopulation, growthRate (birthRate, deathRate));

This code will verify the json independently of param object order.

var isEqualsJson = (obj1,obj2)=>{
    keys1 = Object.keys(obj1);
    keys2 = Object.keys(obj2);

    //return true when the two json has same length and all the properties has same value key by key
    return keys1.length === keys2.length && Object.keys(obj1).every(key=>obj1[key]==obj2[key]);
}

var obj1 = {a:1,b:2,c:3};
var obj2 = {a:1,b:2,c:3}; 

console.log("json is equals: "+ isEqualsJson(obj1,obj2));
alert("json is equals: "+ isEqualsJson(obj1,obj2));

• A global variable has external linkage by default. Its scope can be extended to files other than containing it by giving a matching extern declaration in the other file.
• The scope of a global variable can be restricted to the file containing its declaration by prefixing the declaration with the keyword static. Such variables are said to have internal linkage.

Consider following example:

1.cpp

void f(int i);
extern const int max = 10;
int n = 0;
int main()
{
    int a;
    //...
    f(a);
    //...
    f(a);
    //...
}

1. The signature of function f declares f as a function with external linkage (default). Its definition must be provided later in this file or in other translation unit (given below).
2. max is defined as an integer constant. The default linkage for constants is internal. Its linkage is changed to external with the keyword extern. So now max can be accessed in other files.
3. n is defined as an integer variable. The default linkage for variables defined outside function bodies is external.

2.cpp

#include <iostream>
using namespace std;

extern const int max;
extern int n;
static float z = 0.0;

void f(int i)
{
    static int nCall = 0;
    int a;
    //...
    nCall++;
    n++;
    //...
    a = max * z;
    //...
    cout << "f() called " << nCall << " times." << endl;
}

1. max is declared to have external linkage. A matching definition for max (with external linkage) must appear in some file. (As in 1.cpp)
2. n is declared to have external linkage.
3. z is defined as a global variable with internal linkage.
4. The definition of nCall specifies nCall to be a variable that retains its value across calls to function f(). Unlike local variables with the default auto storage class, nCall will be initialized only once at the start of the program and not once for each invocation of f(). The storage class specifier static affects the lifetime of the local variable and not its scope.

NB: The keyword static plays a double role. When used in the definitions of global variables, it specifies internal linkage. When used in the definitions of the local variables, it specifies that the lifetime of the variable is going to be the duration of the program instead of being the duration of the function.

Hope that helps!

I've had this problem many times before with my Galaxy Nexus. Despite having the Android SDK's USB drivers installed, it did not seem to suffice.

I've always solved this by installing a program called PdaNet. While I don't know exactly what it is used for and where it gets its drivers - it comes with the drivers that has always fixed the problem for me. You can uninstall the program itself once it has finished.

the below code does exactly what you want

//use this intent on click event

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(cameraIntent,CAMERA_REQUEST);

// the above code is used in 'on activity Result'

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);

    if (requestCode == CAMERA_REQUEST) {
        Bitmap photo = (Bitmap) data.getExtras().get("data");
        image.setImageBitmap(photo);
    }
}

A form submission causes the page to navigate away to the action of the form. So, you cannot submit both forms in the traditional way. If you try to do so with JavaScript by calling form.submit() on each form in succession, each request will be aborted except for the last submission. So, you need to submit the first form asynchronously via JavaScript:

var f = document.forms.updateDB;
var postData = [];
for (var i = 0; i < f.elements.length; i++) {
    postData.push(f.elements[i].name + "=" + f.elements[i].value);
}
var xhr = new XMLHttpRequest();
xhr.open("POST", "mypage.php", true);
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.send(postData.join("&"));

document.forms.payPal.submit();

now apple support that

overflow:hidden;
-webkit-overflow-scrolling:touch;

In Java, int is a primitive type and it is not considered an object. Only objects can have a null value. So the answer to your question is no, it can't be null. But it's not that simple, because there are objects that represent most primitive types.

The class Integer represents an int value, but it can hold a null value. Depending on your check method, you could be returning an int or an Integer.

This behavior is different from some more purely object oriented languages like Ruby, where even "primitive" things like ints are considered objects.

I tried several of the suggested solutions, but none of them worked for me. After some research I stumbled upon a hint to move some apps from /data/app to /system/app. That freed up enough space to install new apps and update existing ones.

I can recommend the free utility SystemCleanup for moving the apps.

From the jQuery documentation - http://api.jquery.com/jQuery.ajax/

contentType When sending data to the server, use this content type.

dataType The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response

"text": A plain text string.

So you want contentType to be application/json and dataType to be text:

$.ajax({
    type : "POST",
    url : /v1/user,
    dataType : "text",
    contentType: "application/json",
    data : dataAttribute,
    success : function() {

    },
    error : function(error) {

    }
});

At a major UK bank I was brought in to act as a design authority on a new .NET system.

Their rules state that the database tables had to be a maximum of 8 characters long, with the project code (a 5 digit code) as the prefix.

They were enforcing old DB2 rules onto Windows projects sigh

It is possible that the executable is statically linked and that is why ldd gzip does not see any links - because it isn't. I don't know much about things that far back so I don't know if there would be incompatibilities if libraries are linked in statically. I might expect there to be.

I know it's the most obvious thing going and I'm sure you've done it, but chmod +x ./gzip, yes? No such file or directory is a classic symptom of that not being done, that's why I mention it.

Hi this happens when the front end and backend is running on different ports. The browser blocks the responses from the backend due to the absence on CORS headers. The solution is to make add the CORS headers in the backend request. The easiest way is to use cors npm package.

var express = require('express')
var cors = require('cors')
var app = express()
app.use(cors())

This will enable CORS headers in all your request. For more information you can refer to cors documentation

https://www.npmjs.com/package/cors

!!! I had a similar problem and I found that in my case the withCredentials: true in the request was activating the CORS check while issuing the same in the header would avoid the check:

https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS/Errors/CORSMIssingAllowCredentials

do not use withCredentials: true but set 'Access-Control-Allow-Credentials':true in the headers

For removing document, I prefer using Model.remove(conditions, [callback])

Please refer API documentation for remove :-

http://mongoosejs.com/docs/api.html#model_Model.remove

For this case, code will be:-

FBFriendModel.remove({ id : 333 }, function(err, callback){
console.log(‘Do Stuff’);
})

If you want to remove documents without waiting for a response from MongoDB, do not pass a callback, then you need to call exec on the returned Query

var removeQuery = FBFriendModel.remove({id : 333 });
removeQuery.exec();

The closest thing to renaming is deleting and then re-creating on the remote. For example:

git branch -m master master-old
git push remote :master         # delete master
git push remote master-old      # create master-old on remote

git checkout -b master some-ref # create a new local master
git push remote master          # create master on remote

However this has a lot of caveats. First, no existing checkouts will know about the rename - git does not attempt to track branch renames. If the new master doesn't exist yet, git pull will error out. If the new master has been created. the pull will attempt to merge master and master-old. So it's generally a bad idea unless you have the cooperation of everyone who has checked out the repository previously.

Note: Newer versions of git will not allow you to delete the master branch remotely by default. You can override this by setting the receive.denyDeleteCurrent configuration value to warn or ignore on the remote repository. Otherwise, if you're ready to create a new master right away, skip the git push remote :master step, and pass --force to the git push remote master step. Note that if you're not able to change the remote's configuration, you won't be able to completely delete the master branch!

This caveat only applies to the current branch (usually the master branch); any other branch can be deleted and recreated as above.

            Button b2 = (Button) findViewById(R.id.button2);
            final TextView t = (TextView) findViewById(R.id.textView1);

            b.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    stopPlaying();
                    mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.far);
                    mp.start();
                }

            });

            b2.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    stopPlaying();
                    mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.beet);
                    mp.start();
                }
            });
        }

        private void stopPlaying() {
            if (mp != null) {
                mp.stop();
                mp.release();
                mp = null;
           }

There is no difference between the objects; you have a HashMap<String, Object> in both cases. There is a difference in the interface you have to the object. In the first case, the interface is HashMap<String, Object>, whereas in the second it's Map<String, Object>. But the underlying object is the same.

The advantage to using Map<String, Object> is that you can change the underlying object to be a different kind of map without breaking your contract with any code that's using it. If you declare it as HashMap<String, Object>, you have to change your contract if you want to change the underlying implementation.

Example: Let's say I write this class:

class Foo {
    private HashMap<String, Object> things;
    private HashMap<String, Object> moreThings;

    protected HashMap<String, Object> getThings() {
        return this.things;
    }

    protected HashMap<String, Object> getMoreThings() {
        return this.moreThings;
    }

    public Foo() {
        this.things = new HashMap<String, Object>();
        this.moreThings = new HashMap<String, Object>();
    }

    // ...more...
}

The class has a couple of internal maps of string->object which it shares (via accessor methods) with subclasses. Let's say I write it with HashMaps to start with because I think that's the appropriate structure to use when writing the class.

Later, Mary writes code subclassing it. She has something she needs to do with both things and moreThings, so naturally she puts that in a common method, and she uses the same type I used on getThings/getMoreThings when defining her method:

class SpecialFoo extends Foo {
    private void doSomething(HashMap<String, Object> t) {
        // ...
    }

    public void whatever() {
        this.doSomething(this.getThings());
        this.doSomething(this.getMoreThings());
    }

    // ...more...
}

Later, I decide that actually, it's better if I use TreeMap instead of HashMap in Foo. I update Foo, changing HashMap to TreeMap. Now, SpecialFoo doesn't compile anymore, because I've broken the contract: Foo used to say it provided HashMaps, but now it's providing TreeMaps instead. So we have to fix SpecialFoo now (and this kind of thing can ripple through a codebase).

Unless I had a really good reason for sharing that my implementation was using a HashMap (and that does happen), what I should have done was declare getThings and getMoreThings as just returning Map<String, Object> without being any more specific than that. In fact, barring a good reason to do something else, even within Foo I should probably declare things and moreThings as Map, not HashMap/TreeMap:

class Foo {
    private Map<String, Object> things;             // <== Changed
    private Map<String, Object> moreThings;         // <== Changed

    protected Map<String, Object> getThings() {     // <== Changed
        return this.things;
    }

    protected Map<String, Object> getMoreThings() { // <== Changed
        return this.moreThings;
    }

    public Foo() {
        this.things = new HashMap<String, Object>();
        this.moreThings = new HashMap<String, Object>();
    }

    // ...more...
}

Note how I'm now using Map<String, Object> everywhere I can, only being specific when I create the actual objects.

If I had done that, then Mary would have done this:

class SpecialFoo extends Foo {
    private void doSomething(Map<String, Object> t) { // <== Changed
        // ...
    }

    public void whatever() {
        this.doSomething(this.getThings());
        this.doSomething(this.getMoreThings());
    }
}

...and changing Foo wouldn't have made SpecialFoo stop compiling.

Interfaces (and base classes) let us reveal only as much as is necessary, keeping our flexibility under the covers to make changes as appropriate. In general, we want to have our references be as basic as possible. If we don't need to know it's a HashMap, just call it a Map.

This isn't a blind rule, but in general, coding to the most general interface is going to be less brittle than coding to something more specific. If I'd remembered that, I wouldn't have created a Foo that set Mary up for failure with SpecialFoo. If Mary had remembered that, then even though I messed up Foo, she would have declared her private method with Map instead of HashMap and my changing Foo's contract wouldn't have impacted her code.

Sometimes you can't do that, sometimes you have to be specific. But unless you have a reason to be, err toward the least-specific interface.

Its simple just close the specified text like this for example <b>"your text here:"</b>

<string name="headquarters">"<b>"Headquarters:"</b>" Mooresville, North Carolina, U.S.</string>

result: Headquarters: Mooresville, North Carolina, U.S.

The disabled attribute is not global and is only allowed on form controls. What you could do is set a custom data attribute (perhaps data-disabled) and check for that attribute when you handle the click event.

NSDate and the timeIntervalSince* methods will return a NSTimeInterval which is a double with sub-millisecond accuracy. NSTimeInterval is in seconds, but it uses the double to give you greater precision.

In order to calculate millisecond time accuracy, you can do:

// Get a current time for where you want to start measuring from
NSDate *date = [NSDate date];

// do work...

// Find elapsed time and convert to milliseconds
// Use (-) modifier to conversion since receiver is earlier than now
double timePassed_ms = [date timeIntervalSinceNow] * -1000.0;

Documentation on timeIntervalSinceNow.

There are many other ways to calculate this interval using NSDate, and I would recommend looking at the class documentation for NSDate which is found in NSDate Class Reference.

No idea why the cast works, but Foo::MEMBER isn't allocated until the first time Foo is loaded, and since you're never loading it, it's never allocated. If you had a reference to a Foo somewhere, it would probably work.

You could also use GenerationType.TABLE instead of IDENTITY which is only available after the insert.

Whitespace just means characters which are used for spacing, and have an "empty" representation. In the context of python, it means tabs and spaces (it probably also includes exotic unicode spaces, but don't use them). The definitive reference is here: http://docs.python.org/2/reference/lexical_analysis.html#indentation

I'm not sure exactly how to use it.

Put it at the front of the line you want to indent. If you mix spaces and tabs, you'll likely see funky results, so stick with one or the other. (The python community usually follows PEP8 style, which prescribes indentation of four spaces).

You need to create a new indent level after each colon:

for x in range(0, 50):
    print x
    print 2*x

print x

In this code, the first two print statements are "inside" the body of the for statement because they are indented more than the line containing the for. The third print is outside because it is indented less than the previous (nonblank) line.

If you don't indent/unindent consistently, you will get indentation errors. In addition, all compound statements (i.e. those with a colon) can have the body supplied on the same line, so no indentation is required, but the body must be composed of a single statement.

Finally, certain statements, like lambda feature a colon, but cannot have a multiline block as the body.

In your case, it will produce an error. :-)

Set assigns an object reference. For all other assignments the (implicit, optional, and little-used) Let statement is correct:

Set object = New SomeObject
Set object = FunctionReturningAnObjectRef(SomeArgument)

Let i = 0
Let i = FunctionReturningAValue(SomeArgument)

' or, more commonly '

i = 0
i = FunctionReturningAValue(SomeArgument)

As your list is an ArrayList, it can be assumed that it is unsorted. Therefore, there is no way to search for your element that is faster than O(n).

If you can, you should think about changing your list into a Set (with HashSet as implementation) with a specific Comparator for your sample class.

Another possibility would be to use a HashMap. You can add your data as Sample (please start class names with an uppercase letter) and use the string you want to search for as key. Then you could simply use

Sample samp = myMap.get(myKey);

If there can be multiple samples per key, use Map<String, List<Sample>>, otherwise use Map<String, Sample>. If you use multiple keys, you will have to create multiple maps that hold the same dataset. As they all point to the same objects, space shouldn't be that much of a problem.

stage.getIcons().add(new Image(<yourclassname>.class.getResourceAsStream("/icon.png" )));

You can add more than one icon with different sizes using this method.The images should be different sizes of the same image and the best size will be chosen. eg. 16x16, 32,32

Sorry for reincarnation of this thread again after another 3 years of sleeping, but perhaps I have finally found the indisputable benefit of window.onload=fn1; over <body onload="fn1()">. It concerns the JS modules or ES modules: when your onload handler resides in "classical" JS file (i.e. referred without <script type="module" … >, either way is possible; when your onload handler resides in "module" JS file (i.e. referred with <script type="module" … >, the <body onload="fn1()"> will fail with "fn1() is not defined" error. The reason perhaps is that the ES modules are not loaded before HTML is parsed … but it is just my guess. Anyhow, window.onload=fn1; works perfectly with modules ...

I usually use the excellent Gucharmap to look up Unicode characters. It's installed on all recent Linux installations with Gnome under the name "Character Map". I don't know of any equivalent tools for Windows or Mac OS X, but its homepage lists a few.

Use a cast:

    }
  })
})

3. Check auth on each route change.

// index.js

.run(function ($rootScope, $location) {
  $rootScope.$on('$routeChangeStart', function (ev, next, curr) {
    if (next.$$route) {
      var user = $rootScope.user
      var auth = next.$$route.auth
      if (auth && !auth(user)) { $location.path('/') }
    }
  })
})

Alternatively you can set permissions on the user object and assign each route a permission, then check the permission in the event callback.

Wait, are you really needing to render it using javascript?

Be aware that in HTML5 there is srcdoc, which can do that for you! (The drawback is that IE/EDGE does not support it yet https://caniuse.com/#feat=iframe-srcdoc)

See here [srcdoc]: https://www.w3schools.com/tags/att_iframe_srcdoc.asp

Another thing to note is that if you want to avoid the interference of the js code inside and outside you should consider using the sandbox mode.

See here [sandbox]: https://www.w3schools.com/tags/att_iframe_sandbox.asp

I'm looking for a better LRU cache using Java code. Is it possible for you to share your Java LRU cache code using LinkedHashMap and Collections#synchronizedMap? Currently I'm using LRUMap implements Map and the code works fine, but I'm getting ArrayIndexOutofBoundException on load testing using 500 users on the below method. The method moves the recent object to front of the queue.

private void moveToFront(int index) {
        if (listHead != index) {
            int thisNext = nextElement[index];
            int thisPrev = prevElement[index];
            nextElement[thisPrev] = thisNext;
            if (thisNext >= 0) {
                prevElement[thisNext] = thisPrev;
            } else {
                listTail = thisPrev;
            }
            //old listHead and new listHead say new is 1 and old was 0 then prev[1]= 1 is the head now so no previ so -1
            // prev[0 old head] = new head right ; next[new head] = old head
            prevElement[index] = -1;
            nextElement[index] = listHead;
            prevElement[listHead] = index;
            listHead = index;
        }
    }

get(Object key) and put(Object key, Object value) method calls the above moveToFront method.

I was Forming some Programming Logic Used CHAR(34) for Quotes at Excel : A small Part of same I am posting which can be helpfull ,Hopefully

1   Customers
2   Invoices

Formula Used :

=CONCATENATE("listEvents.Add(",D4,",",CHAR(34),E4,CHAR(34),");")

Result :

listEvents.Add(1,"Customers");
listEvents.Add(2,"Invoices");

You need to use WebConfigurationManager.OpenWebConfiguration(): For Example:

Dim myConfiguration As Configuration = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~")
myConfiguration.ConnectionStrings.ConnectionStrings("myDatabaseName").ConnectionString = txtConnectionString.Text
myConfiguration.AppSettings.Settings.Item("myKey").Value = txtmyKey.Text
myConfiguration.Save()

I think you might also need to set AllowLocation in machine.config. This is a boolean value that indicates whether individual pages can be configured using the element. If the "allowLocation" is false, it cannot be configured in individual elements.

Finally, it makes a difference if you run your application in IIS and run your test sample from Visual Studio. The ASP.NET process identity is the IIS account, ASPNET or NETWORK SERVICES (depending on IIS version).

Might need to grant ASPNET or NETWORK SERVICES Modify access on the folder where web.config resides.

It's because of the Python version. In Python 3 it's import Queue as queue; on the contrary in Python 2.x it's import queue. If you want it for both environments you may use something below as mentioned here

try:
   import queue
except ImportError:
   import Queue as queue

And you can add a max attribute that will specify the highest possible number that you may insert

<input type="number" max="999" />

if you add both a max and a min value you can specify the range of allowed values:

<input type="number" min="1" max="999" />

The above will still not stop a user from manually entering a value outside of the specified range. Instead he will be displayed a popup telling him to enter a value within this range upon submitting the form as shown in this screenshot:

Actions

ADD_PRODUCT : (context,product) => {
  return Axios.post(uri, product).then((response) => {
    if (response.status === 'success') {  
      context.commit('SET_PRODUCT',response.data.data)
    }
    return response.data
  });
});

Component

this.$store.dispatch('ADD_PRODUCT',data).then((res) => {
  if (res.status === 'success') {
    // write your success actions here....
  } else {
     // write your error actions here...
  }
})

I use a single _version.py file as the "once cannonical place" to store version information:

1. It provides a __version__ attribute.

2. It provides the standard metadata version. Therefore it will be detected by pkg_resources or other tools that parse the package metadata (EGG-INFO and/or PKG-INFO, PEP 0345).

3. It doesn't import your package (or anything else) when building your package, which can cause problems in some situations. (See the comments below about what problems this can cause.)

4. There is only one place that the version number is written down, so there is only one place to change it when the version number changes, and there is less chance of inconsistent versions.

Here is how it works: the "one canonical place" to store the version number is a .py file, named "_version.py" which is in your Python package, for example in myniftyapp/_version.py. This file is a Python module, but your setup.py doesn't import it! (That would defeat feature 3.) Instead your setup.py knows that the contents of this file is very simple, something like:

__version__ = "3.6.5"

And so your setup.py opens the file and parses it, with code like:

import re
VERSIONFILE="myniftyapp/_version.py"
verstrline = open(VERSIONFILE, "rt").read()
VSRE = r"^__version__ = ['\"]([^'\"]*)['\"]"
mo = re.search(VSRE, verstrline, re.M)
if mo:
    verstr = mo.group(1)
else:
    raise RuntimeError("Unable to find version string in %s." % (VERSIONFILE,))

Then your setup.py passes that string as the value of the "version" argument to setup(), thus satisfying feature 2.

To satisfy feature 1, you can have your package (at run-time, not at setup time!) import the _version file from myniftyapp/__init__.py like this:

from _version import __version__

Here is an example of this technique that I've been using for years.

The code in that example is a bit more complicated, but the simplified example that I wrote into this comment should be a complete implementation.

Here is example code of importing the version.

If you see anything wrong with this approach, please let me know.

They are formatting String. The Java specific syntax is given in java.util.Formatter.

The general syntax is as follows:

   %[argument_index$][flags][width][.precision]conversion

%02d performs decimal integer conversion d, formatted with zero padding (0 flag), with width 2. Thus, an int argument whose value is say 7, will be formatted into "07" as a String.

You may also see this formatting string in e.g. String.format.

Commonly used formats

These are just some commonly used formats and doesn't cover the syntax exhaustively.

Zero padding for numbers

System.out.printf("Agent %03d to the rescue!", 7);
// Agent 007 to the rescue!

Width for justification

You can use the - flag for left justification; otherwise it'll be right justification.

for (Map.Entry<Object,Object> prop : System.getProperties().entrySet()) {
    System.out.printf("%-30s : %50s%n", prop.getKey(), prop.getValue());
}

This prints something like:

java.version                   :                                 1.6.0_07
java.vm.name                   :               Java HotSpot(TM) Client VM
java.vm.vendor                 :                    Sun Microsystems Inc.
java.vm.specification.name     :       Java Virtual Machine Specification
java.runtime.name              :          Java(TM) SE Runtime Environment
java.vendor.url                :                     http://java.sun.com/

For more powerful message formatting, you can use java.text.MessageFormat. %n is the newline conversion (see below).

Hexadecimal conversion

System.out.println(Integer.toHexString(255));
// ff

System.out.printf("%d is %<08X", 255);
// 255 is 000000FF

Note that this also uses the < relative indexing (see below).

Floating point formatting

System.out.printf("%+,010.2f%n", 1234.567);
System.out.printf("%+,010.2f%n", -66.6666);
// +01,234.57
// -000066.67

For more powerful floating point formatting, use DecimalFormat instead.

%n for platform-specific line separator

System.out.printf("%s,%n%s%n", "Hello", "World");
// Hello,
// World

%% for an actual %-sign

System.out.printf("It's %s%% guaranteed!", 99.99);
// It's 99.99% guaranteed!

Note that the double literal 99.99 is autoboxed to Double, on which a string conversion using toString() is defined.

n$ for explicit argument indexing

System.out.printf("%1$s! %1$s %2$s! %1$s %2$s %3$s!",
    "Du", "hast", "mich"
);
// Du! Du hast! Du hast mich!

< for relative indexing

System.out.format("%s?! %<S?!?!?", "Who's your daddy");
// Who's your daddy?! WHO'S YOUR DADDY?!?!?

As mentioned by the top-voted answer, Martin Fowler discusses these distinctions in Mocks Aren't Stubs, and in particular the subheading The Difference Between Mocks and Stubs, so make sure to read that article.

Rather than focusing on how these things are different, I think it's more enlightening to focus on why these are distinct concepts. Each exists for a different purpose.

Fakes

A fake is an implementation that behaves "naturally", but is not "real". These are fuzzy concepts and so different people have different understandings of what makes things a fake.

One example of a fake is an in-memory database (e.g. using sqlite with the :memory: store). You would never use this for production (since the data is not persisted), but it's perfectly adequate as a database to use in a testing environment. It's also much more lightweight than a "real" database.

As another example, perhaps you use some kind of object store (e.g. Amazon S3) in production, but in a test you can simply save objects to files on disk; then your "save to disk" implementation would be a fake. (Or you could even fake the "save to disk" operation by using an in-memory filesystem instead.)

As a third example, imagine an object that provides a cache API; an object that implements the correct interface but that simply performs no caching at all but always returns a cache miss would be a kind of fake.

The purpose of a fake is not to affect the behavior of the system under test, but rather to simplify the implementation of the test (by removing unnecessary or heavyweight dependencies).

Stubs

A stub is an implementation that behaves "unnaturally". It is preconfigured (usually by the test set-up) to respond to specific inputs with specific outputs.

The purpose of a stub is to get your system under test into a specific state. For example, if you are writing a test for some code that interacts with a REST API, you could stub out the REST API with an API that always returns a canned response, or that responds to an API request with a specific error. This way you could write tests that make assertions about how the system reacts to these states; for example, testing the response your users get if the API returns a 404 error.

A stub is usually implemented to only respond to the exact interactions you've told it to respond to. But the key feature that makes something a stub is its purpose: a stub is all about setting up your test case.

Mocks

A mock is similar to a stub, but with verification added in. The purpose of a mock is to make assertions about how your system under test interacted with the dependency.

For example, if you are writing a test for a system that uploads files to a website, you could build a mock that accepts a file and that you can use to assert that the uploaded file was correct. Or, on a smaller scale, it's common to use a mock of an object to verify that the system under test calls specific methods of the mocked object.

Mocks are tied to interaction testing, which is a specific testing methodology. People who prefer to test system state rather than system interactions will use mocks sparingly if at all.

Test doubles

Fakes, stubs, and mocks all belong to the category of test doubles. A test double is any object or system you use in a test instead of something else. Most automated software testing involves the use of test doubles of some kind or another. Some other kinds of test doubles include dummy values, spies, and I/O blackholes.

Edited answer: IE understands just screen and print as import media. All other CSS supplied along with the import statement causes IE8 to ignore the import statement. Geco browser like safari or mozilla didn't have this problem.

I made API sending data via form on website to prosperworks based on @Rocket Hazmat, @dbau and @maraca code. I hope, it will help somebody:

It happens that /etc/hosts file doesn't support wild card entries.

You'll have to use other services like dnsmasq. To enable it in dnsmasq, just edit dnsmasq.conf and add the following line:

How about PlantUML? It's not for reverse engineering!!! It's for engineering before you code.

In my case, I deleted the Previous Project & created a new project with different name, when i was building the Project it shows me the same error.

I just edited the Project Name in csproj file of the Project & it Worked...!

Probably, you need to insert schema identifier here:

in.addValue("po_system_users", null, OracleTypes.ARRAY, "your_schema.T_SYSTEM_USER_TAB");

String clsName = "Ex";  // use fully qualified name
Class cls = Class.forName(clsName);
Object clsInstance = (Object) cls.newInstance();

I had a similar problem. NuGet showed the package successfully installed, but the reference was not added to my project.

Running <PM> Install-Package Microsoft.Web.InfraStructure also didn't help as the package manager kept saying it's already installed

I finally added it manually by editing the csproj file and adding these lines:

 <Reference Include="Microsoft.Web.Infrastructure">
  <HintPath>..\packages\Microsoft.Web.Infrastructure.1.0.0.0\lib\net40\Microsoft.Web.Infrastructure.dll</HintPath>
  <Private>True</Private>
</Reference>

That solved the problem.

Easiest way to find address path in Excel 2010:

There are some great answers here but I wanted to point out the jvm is free to store a char value in any size space >= 2 bytes.

On many architectures there is a penalty for performing unaligned memory access so a char might easily be padded to 4 bytes. A volatile char might even be padded to the size of the CPU cache line to prevent false sharing. https://en.wikipedia.org/wiki/False_sharing

It might be non-intuitive to new Java programmers that a character array or a string is NOT simply multiple characters. You should learn and think about strings and arrays distinctly from "multiple characters".

I also want to point out that java characters are often misused. People don't realize they are writing code that won't properly handle codepoints over 16 bits in length.

I had the same problem today. I tested for four things, some of them already mentioned here:

1. Are there any values in your child column that don't exist in the parent column (besides NULL, if the child column is nullable)

2. Do child and parent columns have the same datatype?

3. Is there an index on the parent column you are referencing? MySQL seems to require this for performance reasons (http://dev.mysql.com/doc/refman/5.5/en/create-table-foreign-keys.html)

4. And this one solved it for me: Do both tables have identical collation?

I had one table in UTF-8 and the other in iso-something. That didn't work. After changing the iso-table to UTF-8 collation the constraints could be added without problems. In my case, phpMyAdmin didn't even show the child table in iso-encoding in the dropdown for creating the foreign key constraint.

You can try this it will recursively find all key values in a json object and constructs as a map . You can simply get which key you want from the Map .

public static Map<String,String> parse(JSONObject json , Map<String,String> out) throws JSONException{
    Iterator<String> keys = json.keys();
    while(keys.hasNext()){
        String key = keys.next();
        String val = null;
        try{
             JSONObject value = json.getJSONObject(key);
             parse(value,out);
        }catch(Exception e){
            val = json.getString(key);
        }

        if(val != null){
            out.put(key,val);
        }
    }
    return out;
}

 public static void main(String[] args) throws JSONException {

    String json = "{'ipinfo': {'ip_address': '131.208.128.15','ip_type': 'Mapped','Location': {'continent': 'north america','latitude': 30.1,'longitude': -81.714,'CountryData': {'country': 'united states','country_code': 'us'},'region': 'southeast','StateData': {'state': 'florida','state_code': 'fl'},'CityData': {'city': 'fleming island','postal_code': '32003','time_zone': -5}}}}";

    JSONObject object = new JSONObject(json);

    JSONObject info = object.getJSONObject("ipinfo");

    Map<String,String> out = new HashMap<String, String>();

    parse(info,out);

    String latitude = out.get("latitude");
    String longitude = out.get("longitude");
    String city = out.get("city");
    String state = out.get("state");
    String country = out.get("country");
    String postal = out.get("postal_code");

    System.out.println("Latitude : " + latitude + " LongiTude : " + longitude + " City : "+city + " State : "+ state + " Country : "+country+" postal "+postal);

    System.out.println("ALL VALUE " + out);

}

Output:

    Latitude : 30.1 LongiTude : -81.714 City : fleming island State : florida Country : united states postal 32003
ALL VALUE {region=southeast, ip_type=Mapped, state_code=fl, state=florida, country_code=us, city=fleming island, country=united states, time_zone=-5, ip_address=131.208.128.15, postal_code=32003, continent=north america, longitude=-81.714, latitude=30.1}

In addition to using KeyListener (as shown by others' answers), sometimes you have to ensure that the JComponent you are using is Focusable. This can be set by adding this to your component(if you are subclassing):

@Override
public void setFocusable(boolean b) {
    super.setFocusable(b);
}

And by adding this to your constructor:

setFocusable(true);

Or, if you are calling the function from a parent class/container:

JComponent childComponent = new JComponent();
childComponent.setFocusable(true);

And then doing all the KeyListener stuff mentioned by others.

As this Spring's Jira ticket, it is an intentional design. But the following code works for me.

public static Map<String, Object> getAllKnownProperties(Environment env) {
    Map<String, Object> rtn = new HashMap<>();
    if (env instanceof ConfigurableEnvironment) {
        for (PropertySource<?> propertySource : ((ConfigurableEnvironment) env).getPropertySources()) {
            if (propertySource instanceof EnumerablePropertySource) {
                for (String key : ((EnumerablePropertySource) propertySource).getPropertyNames()) {
                    rtn.put(key, propertySource.getProperty(key));
                }
            }
        }
    }
    return rtn;
}

If you want something that works and is future-proof, use a library like MomentJS.

moment(date).week();
moment(date).isoWeek()

http://momentjs.com/docs/#/get-set/week/

Let's say you have an array of IDs and equivalent array of statuses - here is an example how to do this with a static SQL (a sql query that doesn't change due to different values) of the arrays :

drop table if exists results_dummy;
create table results_dummy (id int, status text, created_at timestamp default now(), updated_at timestamp default now());
-- populate table with dummy rows
insert into results_dummy
(id, status)
select unnest(array[1,2,3,4,5]::int[]) as id, unnest(array['a','b','c','d','e']::text[]) as status;

select * from results_dummy;

-- THE update of multiple rows with/by different values
update results_dummy as rd
set    status=new.status, updated_at=now()
from (select unnest(array[1,2,5]::int[]) as id,unnest(array['a`','b`','e`']::text[]) as status) as new
where rd.id=new.id;

select * from results_dummy;

-- in code using **IDs** as first bind variable and **statuses** as the second bind variable:
update results_dummy as rd
set    status=new.status, updated_at=now()
from (select unnest(:1::int[]) as id,unnest(:2::text[]) as status) as new
where rd.id=new.id;

This might work out for you depending on which language you are using:

(?<=Object Name:).*

It's a positive lookbehind assertion. More information could be found here.

It won't work with JavaScript though. In your comment I read that you're using it for logstash. If you are using GROK parsing for logstash then it would work. You can verify it yourself here:

https://grokdebug.herokuapp.com/

If you're dealing with an input element, I found it useful to set the pointer focus to back itself.

$('input').on('keydown', function(e) { 
    if (e.keyCode == 9) {
        $(this).focus();
       e.preventDefault();
    }
});

I just tried this, maybe it suits your needs. Depending on the number of the arguments, you can access a different function. You initialize it the first time you call it. And the function map is hidden in the closure.

TEST = {};

TEST.multiFn = function(){
    // function map for our overloads
    var fnMap = {};

    fnMap[0] = function(){
        console.log("nothing here");
        return this;    //    support chaining
    }

    fnMap[1] = function(arg1){
        //    CODE here...
        console.log("1 arg: "+arg1);
        return this;
    };

    fnMap[2] = function(arg1, arg2){
        //    CODE here...
        console.log("2 args: "+arg1+", "+arg2);
        return this;
    };

    fnMap[3] = function(arg1,arg2,arg3){
        //    CODE here...
        console.log("3 args: "+arg1+", "+arg2+", "+arg3);
        return this;
    };

    console.log("multiFn is now initialized");

    //    redefine the function using the fnMap in the closure
    this.multiFn = function(){
        fnMap[arguments.length].apply(this, arguments);
        return this;
    };

    //    call the function since this code will only run once
    this.multiFn.apply(this, arguments);

    return this;    
};

Test it.

TEST.multiFn("0")
    .multiFn()
    .multiFn("0","1","2");

Had that issue on Ubuntu 14.04, In my case I had also libXtst.so missing:

Could not open library 'libXtst.so': libXtst.so: cannot open shared object 
file: No such file or directory

Make sure your symbolic link is pointing to proper file, cd /usr/lib/x86_64-linux-gnu and list libXtst with:

 ll |grep libXtst                                                                                                                                                           
 lrwxrwxrwx   1 root root        16 Oct  7  2016 libXtst.so.6 -> libXtst.so.6.1.0
 -rw-r--r--   1 root root     22880 Aug 16  2013 libXtst.so.6.1.0

Then just create proper symbolic link using:

sudo ln -s libXtst.so.6 libXtst.so

List again:

ll | grep libXtst
lrwxrwxrwx   1 root root        12 Sep 20 10:23 libXtst -> libXtst.so.6
lrwxrwxrwx   1 root root        12 Sep 20 10:23 libXtst.so -> libXtst.so.6
lrwxrwxrwx   1 root root        16 Oct  7  2016 libXtst.so.6 -> libXtst.so.6.1.0
-rw-r--r--   1 root root     22880 Aug 16  2013 libXtst.so.6.1.0

all set!

here is my solution using c++ if brackets are matched then returns true if not then gives false

#include <iostream>
#include <stack>
#include <string.h>
using namespace std;

int matchbracket(string expr){
    stack<char> st;
    int i;
    char x;
    for(i=0;i<expr.length();i++){
        if(expr[i]=='('||expr[i]=='{'||expr[i]=='[')
          st.push(expr[i]);
          
        if(st.empty())
         return -1;
        switch(expr[i]){
            case ')' :
             x=expr[i];
             st.pop();
             if(x=='}'||x==']')
              return 0;
              break;
            
            case '}' :
             x=expr[i];
             st.pop();
             if(x==')'||x==']')
              return 0;
              break;
        
            case ']' :
            x=expr[i];
            st.pop();
            if(x==')'||x=='}')
             return 1;
             break;
        } 

    }
    return(st.empty());
}

int main()
{
 string expr;
 cin>>expr;
 
 if(matchbracket(expr)==1)
  cout<<"\nTRUE\n";
  else
  cout<<"\nFALSE\n";
}

A quick and easy solution for those who don't have much deviation from default VS settings.

Tools-->Import and Export Settings-->Yes, save my current settings-->Visual C#

I am sure the above solution would work with other default settings too. In my case something messed up with my symbol loading settings but I could not fix it even though I tried quite a few of the suggested solutions.

Answer 1:

• Downloading bootstrap through npm (or bower) permits you to gain some latency time. Instead of getting a remote resource, you get a local one, it's quicker, except if you use a cdn (check below answer)

• "npm" was originally to get Node Module, but with the essort of the Javascript language (and the advent of browserify), it has a bit grown up. In fact, you can even download AngularJS on npm, that is not a server side framework. Browserify permits you to use AMD/RequireJS/CommonJS on client side so node modules can be used on client side.

Answer 2:

If you npm install bootstrap (if you dont use a particular grunt or gulp file to move to a dist folder), your bootstrap will be located in "./node_modules/bootstrap/bootstrap.min.css" if I m not wrong.

if you care for the whole page. you can use this:

document.body.getBoundingClientRect().top

What frameworks do you use?

We use a mix of the logging application block, and a custom logging helper that works around the .Net framework bits. The LAB is configured to output fairly extensive log files included seperate general trace files for service method entry/exit and specific error files for unexpected issues. The configuration includes date/time, thread, pId etc. for debug assistance as well as the full exception detail and stack (in the case of an unexpected exception).

The custom logging helper makes use of the Trace.Correlation and is particularly handy in the context of logging in WF. For example we have a state machine that invokes a series of sequential workflows. At each of these invoke activities we log the start (using StartLogicalOperation) and then at the end we stop the logical operation with a gereric return event handler.

This has proven useful a few times when attempting to debug failures in complex business sequences as it allows us to determine things like If/Else branch decisions etc. more quickly based on the activity execution sequence.

What log outputs do you use?

We use text files and XML files. Text files are configured through the app block but we've got XML outputs as well from our WF service. This enables us to capture the runtime events (persistence etc.) as well as generic business type exceptions. The text files are rolling logs that are rolled by day and size (I believe total size of 1MB is a rollover point).

What tools to you use for viewing the logs?

We are using Notepad and WCF Service Trace Viewer depending on which output group we're looking at. The WCF Service Trace Viewer is really really handy if you've got your output setup correctly and can make reading the output much simpler. That said, if I know roughly where the error is anyway - just reading a well annotated text file is good as well.

The logs are sent to a single directory which is then split into sub-dirs based on the source service. The root dir is exposed via a website which has it's access controlled by a support user group. This allows us to take a look at production logs without having to put in requests and go through lengthy red tape processes for production data.

Pull from the repository to a new directory, then rename the old one to old_crufty, and the new one to my_real_webserver_directory, and you're good to go.

If your intention is that every single file is in SVN, then this is a good way to test your theory. If your intention is that some files are not in SVN, then use Brian's copy/paste technique.

you need length() function

select length(customer_name) from ar.ra_customers

Because JavaScript is such a small language, yet with incredible complexity, you should be able to ask relatively basic questions and find out if they are really that good based on their answers. For instance, my standard first question to gauge the rest of the interview is:

In JavaScript, what is the difference between var x = 1 and x = 1? Answer in as much or as little detail as you feel comfortable.

Novice JS programmers might have a basic answer about locals vs globals. Intermediate JS guys should definitely have that answer, and should probably mention function-level scope. Anyone calling themselves an "advanced" JS programmer should be prepared to talk about locals, implied globals, the window object, function-scope, declaration hoisting, and scope chains. Furthermore, I'd love to hear about [[DontDelete]], hoisting precedence (parameters vs var vs function), and undefined.

Another good question is to ask them to write a sum() function that accepts any number of arguments, and returns their sum. Then, ask them to use that function (without modification) to sum all the values in an array. They should write a function that looks like this:

function sum() {
  var i, l, result = 0;
  for (i = 0, l = arguments.length; i < l; i++) {
    result += arguments[i];
  }
  return result;
}
sum(1,2,3); // 6

And they should invoke it on your array like this (context for apply can be whatever, I usually use null in that case):

var data = [1,2,3];
sum.apply(null, data); // 6

If they've got those answers, they probably know their JavaScript. You should then proceed to asking them about non-JS specific stuff like testing, workflows, version control, etc. to find out if they're a good programmer.

Compare date only instead of date + time (NOW) with:

CURDATE()

Another way to do this is to use the numpy matrix class (rather than a numpy array) and the I attribute. For example:

>>> m = np.matrix([[2,3],[4,5]])
>>> m.I
matrix([[-2.5,  1.5],
       [ 2. , -1. ]])

Connection.Response resp = Jsoup.connect(url) //
                .timeout(20000) //
                .method(Connection.Method.GET) //
                .execute();

actually, the error occurs when you have slow internet so try to maximize the timeout time and then your code will definitely work as it works for me.

It is clear that tvi.header is not a String. The == is an operator that is overloaded by String class, which means it will be working only if compiler knows that both side of the operator are String.

Your problem has nothing to do with encodings, it's a simple matter of understanding basic C++. You are returning a pointer to a local variable from your function, which will have gone out of scope by the time anyone can use it, thus creating undefined behaviour (i.e. a programming error).

Follow this Golden Rule: "If you are using naked char pointers, you're Doing It Wrong. (Except for when you aren't.)"

I've previously posted some code to do the conversion and communicating the input and output in C++ std::string and std::wstring objects.

For PHP >= 5.4 you can use a simpler function like this : http_response_code(404);
PHP Documentation

from the command line: for /R /D %1 in (*) do rd "%1"

in a batch file for /R /D %%1 in (*) do rd "%%1"

I don't know if it's documented as such, but it works in W2K, XP, and Win 7. And I don't know if it will always work, but it won't ever delete files by accident.

This answer is similar to other however as some people have been complaining that the output goes to STDOUT i am just going to suggest redirecting it to the original file and overwriting it. I would never normally suggest this but sometimes quick and dirty works.

cat file.txt | tr -d " \t\n\r" > file.txt

The server.contextPath or server.context-path works if

in pom.xml

1. packing should be war not jar

2. Add following dependencies

   <dependency>
       <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   <!-- Tomcat/TC server -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-tomcat</artifactId>
       <scope>provided</scope>
    </dependency>
   

   In eclipse, right click on project --> Run as --> Spring Boot App.

You have a space delimited file, so use the module designed for reading delimited values files, csv.

import csv

with open('path/to/file.txt') as inf:
    reader = csv.reader(inf, delimiter=" ")
    second_col = list(zip(*reader))[1]
    # In Python2, you can omit the `list(...)` cast

The zip(*iterable) pattern is useful for converting rows to columns or vice versa. If you're reading a file row-wise...

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

>>> for line in testdata:
...     print(line)

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

...but need columns, you can pass each row to the zip function

>>> testdata_columns = zip(*testdata)
# this is equivalent to zip([1,2,3], [4,5,6], [7,8,9])

>>> for line in testdata_columns:
...     print(line)

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

We can simply map a Controller method for the default view. For eg, we have a index.html as the default page.

@RequestMapping(value = "/", method = GET)
public String index() {
    return "index";
}

once done we can access the page with default application context.

E.g http://localhost:8080/myapp

This might help for people ending up here searching how to sort list alphabetically.

This is untested, but I believe the syntax should work for a lambda query. As you join more tables with this syntax you have to drill further down into the new objects to reach the values you want to manipulate.

var fullEntries = dbContext.tbl_EntryPoint
    .Join(
        dbContext.tbl_Entry,
        entryPoint => entryPoint.EID,
        entry => entry.EID,
        (entryPoint, entry) => new { entryPoint, entry }
    )
    .Join(
        dbContext.tbl_Title,
        combinedEntry => combinedEntry.entry.TID,
        title => title.TID,
        (combinedEntry, title) => new 
        {
            UID = combinedEntry.entry.OwnerUID,
            TID = combinedEntry.entry.TID,
            EID = combinedEntry.entryPoint.EID,
            Title = title.Title
        }
    )
    .Where(fullEntry => fullEntry.UID == user.UID)
    .Take(10);

This should work nicely:

UPDATE tb_Company SET CompanyIndustry = 
CONCAT(UPPER(LEFT(CompanyIndustry, 1)), SUBSTRING(CompanyIndustry, 2))

You should iterate over the keys and get the values using square brackets.

#include <sstream> and use the fully qualified name i.e. std::stringstream ss;

This works fine

<?php
      $con=mysqli_connect("localhost","my_user","my_password","my_db");
      $con->query("SET GLOBAL time_zone = 'Asia/Calcutta'");
      $con->query("SET time_zone = '+05:30'");

I am using this function:

public static int[][] copy(final int[][] array) {
    if (array != null) {
        final int[][] copy = new int[array.length][];

        for (int i = 0; i < array.length; i++) {
            final int[] row = array[i];

            copy[i] = new int[row.length];
            System.arraycopy(row, 0, copy[i], 0, row.length);
        }

        return copy;
    }

    return null;
}

The big advantage of this approach is that it can also copy arrays that don't have the same row count such as:

final int[][] array = new int[][] { { 5, 3, 6 }, { 1 } };

Try to format your date with the Z or z timezone flags:

new SimpleDateFormat("MM/dd/yyyy KK:mm:ss a Z").format(dateObj);

Not the most beautiful way of doing it I guess:

git log --pretty=oneline | wc -l

This gives you a number then

git log HEAD~<The number minus one>

  copy: src={{ item.src }} dest={{ item.dest }}
  with_items:

You can try to add some time.sleep calls to your code.

It seems like the server side limits the amount of requests per timeunit (hour, day, second) as a security issue. You need to guess how many (maybe using another script with a counter?) and adjust your script to not surpass this limit.

In order to avoid your code from crashing, try to catch this error with try .. except around the urllib2 calls.

Write yourself an extension method

public static class ArrayExtensions {

            originalArray[i] = with;
        }
    }  
}

and use it like

int foo[] = new int[]{0,0,0,0,0};
foo.Fill(13);

will fill all the elements with 13

:set paste is your friend I use putty and end up copying code between windows. Before I was turned on to :set paste (and :set nopaste) copy/paste gave me fits for that very reason.

In python, this is called "unpacking", and you can find a bit about it in the tutorial. The documentation of it sucks, I agree, especially because of how fantasically useful it is.

You can do it as below.

$(this).prev('input').val("hello world");

Try this:

$("#upload_link,#upload_link2,#upload_link3").each(function(){
    $(this).upload({
        //whateveryouwant
    });
});

In a number of cases the performance impact of SSL handshakes will be mitigated by the fact that the SSL session can be cached on both ends (desktop and server). On Windows machines for example the SSL session can be cached for up to 10 hours. See http://support.microsoft.com/kb/247658/EN-US . Some SSL accelerators will also have parameters allowing you to tune the time the session is cached.

Another impact to consider is that static content served over HTTPS will not be cached by proxies, and this may reduce performance across multiple users accessing the site over the same proxy. This can be mitigated by the fact that static content will be cached at desktops as well, Internet Explorer versions 6 and 7 cache cacheable HTTPS static content unless instructed to do otherwise (Tools Menu/Internet Options/Advanced/Security/Do not save encrypted pages to disk).

Everything in MySQL seems to be done closer to the metal than in MSSQL, And the documentation treats it that way. Especially for optimization, you'll need to understand how indexes, system configuration, and the optimizer interact under various circumstances.

The "optimizer" is more a parser. In MSSQL your query plan is often a surprise (usually good, sometimes not). In MySQL, it pretty much does what you asked it to do, the way you expected it to. Which means you yourself need to have a deep understanding of the various ways it might be done.

Not built around a good TRANSACTION model (default MyISAM engine).

File-system setup is your problem.

All the database configuration is your problem - especially various cache sizes.

Sometimes it seems best to think of it as an ad-hoc, glorified isam. Codd and Date don't carry much weight here. They would say it with no embarrassment.

Regarding the freezing issue, we found this occurred when processing CSV files with at least one extremely long line.

[print(x) for x in (['A' * 54790] + (['a' * 1421] * 10))]

However, it appears to have been fixed in PyCharm 4.5.4, so if you experience this, try updating your PyCharm.

additional information for same problem if you are using bitbucket pipeline

edit your message

git commit --amend

push to the sever

git push --force <repository> <branch>

then add --force to your push command on the pipeline

git ftp push --force

This will delete your previous commit(s) and push your current one.

remove the --force after first push

i tried it on bitbucket pipeline and its working fine

ruby:

ruby -ne 'print $stdin.eof ? $_.strip : $_'

or:

ruby -ane 'q=p;p=$_;puts q if $.>1;END{print p.strip!}'
