All answers are correct. Meta-inf has many purposes. In addition, here is an example about using tomcat container.

Go to Tomcat Doc and check " Standard Implementation > copyXML " attribute.

Description is below.

Set to true if you want a context XML descriptor embedded inside the application (located at /META-INF/context.xml) to be copied to the owning Host's xmlBase when the application is deployed. On subsequent starts, the copied context XML descriptor will be used in preference to any context XML descriptor embedded inside the application even if the descriptor embedded inside the application is more recent. The flag's value defaults to false. Note if the deployXML attribute of the owning Host is false or if the copyXML attribute of the owning Host is true, this attribute will have no effect.

Apparently, the system I was using had the docker-ce not Docker. Thus, running below command did the trick.

sudo apt-get purge docker-ce

sudo rm -rf /var/lib/docker

hope it helps

I don't believe Windows (as opposed to .NET) provides a direct way to get that.

The only way I know of is to enumerate all the top level windows with EnumWindows() and then find what process each belongs to GetWindowThreadProcessID(). This sounds indirect and inefficient, but it's not as bad as you might expect -- in a typical case, you might have a dozen top level windows to walk through...

I have been finding Answer for my application and here is the answer for Kotlin Language.

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)
plt.show()

If you want to truncate by a number of words and add an ellipsis you can use this function:

truncate(value: string, limit: number = 40, trail: String = '…'): string {
  let result = value || '';

  if (value) {
    const words = value.split(/\s+/);
    if (words.length > Math.abs(limit)) {
      if (limit < 0) {
        limit *= -1;
        result = trail + words.slice(words.length - limit, words.length).join(' ');
      } else {
        result = words.slice(0, limit).join(' ') + trail;
      }
    }
  }

  return result;
}

Example:

truncate('Bacon ipsum dolor amet sirloin tri-tip swine', 5, '…')
> "Bacon ipsum dolor amet sirloin…"

taken from: https://github.com/yellowspot/ng2-truncate/blob/master/src/truncate-words.pipe.ts

If you want to truncate by a number of letters but don't cut words out use this:

truncate(value: string, limit = 25, completeWords = true, ellipsis = '…') {
  let lastindex = limit;
  if (completeWords) {
    lastindex = value.substr(0, limit).lastIndexOf(' ');
  }
  return `${value.substr(0, limit)}${ellipsis}`;
}

Example:

truncate('Bacon ipsum dolor amet sirloin tri-tip swine', 19, true, '…')
> "Bacon ipsum dolor…"

truncate('Bacon ipsum dolor amet sirloin tri-tip swine', 19, false, '…')
> "Bacon ipsum dolor a…"

document.writeln() is what you are looking for or document.write('\n' + 'words') if you are looking for more granularity in when the new line is used

To fix this problem . first you must add latestandroid-support-v7-appcompat from the \sdk\extras\android\support

1. Close the main project.
2. Remove the android-support-v7-appcompat .
3. Restart the Eclipse.
4. Add the android-support-v7-appcompat .
5. Clean,To build the project.
6. Then open the main project and build all the projects.
7. The error still remains. Restart eclipse. That's it.

That works for me and I will strongly recommend you to use Android Studio.

I believe a short video showing all the details if you have Anaconda is the following for mac (it is very similar to windows users as well) just open Anaconda navigator and everything is just the same (almost!)

https://www.youtube.com/watch?v=gDzAm25CORk

Then go to jupyter notebook and code

!pip install tensorflow

Then

import tensorflow as tf

It work for me! :)

First you should learn about loops, in this case most suitable is for loop. For instance let's initialize whole table with increasing values starting with 0:

final int SIZE = 10;
int[] array = new int[SIZE];
for (int i = 0; i < SIZE; i++) {
    array[i] = i;
}

Now you can modify it to initialize your table with values as per your assignment. But what happen if you replace condition i < SIZE with i < 11? Well, you will get IndexOutOfBoundException, as you try to access (at some point) an object under index 10, but the highest index in 10-element array is 9. So you are trying, in other words, to find friend's home with number 11, but there are only 10 houses in the street.

In case of the code you presented, well, there must be more of it, as you can not get this error (exception) from that code.

Podfile.lock file right under Podfile within your project.

The main thing is , Force it to open through your favourite TextEditor, like Sublime or TextEdit [Open With -> Select Sublime] as it doesn't give an option straight away to open.

try a negative margin.

margin-top: -10px; /* as an example */

Here is the simple ListView with different images. First of all you have to copy the different kinds of images and paste it to the res/drawable-hdpi in your project. Images should be (.png)file format. then copy this code.

In main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:orientation="vertical" >

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

 <ListView
     android:id="@+id/listview"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content" />

create listview_layout.xml and paste this code

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

   <ImageView
      android:id="@+id/flag"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:contentDescription="@string/hello"
      android:paddingTop="10dp"
      android:paddingRight="10dp"
      android:paddingBottom="10dp" />

   <LinearLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical" >

     <TextView
        android:id="@+id/txt"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="15dp"
        android:text="TextView1" />

    <TextView
        android:id="@+id/cur"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="10dp"

This is the full code.you can make changes to your need... Comments are welcome

If you specifically don't want to compare contents of files and only check which one are not present in both of the directories, you can compare lists of files, generated by another command.

diff <(find DIR1 -printf '%P\n' | sort) <(find DIR2 -printf '%P\n' | sort) | grep '^[<>]'

-printf '%P\n' tells find to not prefix output paths with the root directory.

I've also added sort to make sure the order of files will be the same in both calls of find.

The grep at the end removes information about identical input lines.

Try this

<input name="selector[]" id="ad_Checkbox1" class="ads_Checkbox" type="checkbox" value="1" />
<input name="selector[]" id="ad_Checkbox2" class="ads_Checkbox" type="checkbox" value="2" />
<input name="selector[]" id="ad_Checkbox3" class="ads_Checkbox" type="checkbox" value="3" />
<input name="selector[]" id="ad_Checkbox4" class="ads_Checkbox" type="checkbox" value="4" />
<input type="button" id="save_value" name="save_value" value="Save" />

function

    $(function(){
      $('#save_value').click(function(){
        var val = [];
        $(':checkbox:checked').each(function(i){
          val[i] = $(this).val();
        });
      });
    });

The problem is that MYSQL server is not installed. You can get the installer from here

Then watch this 6 minute installation tutorial.

If then creating a new connection in MYSQL Workbench is not working, make sure you run that connection as root as show below:

If you don't find your .ini file check this answer.

Try this

on change event

$("#jodSel").on('change',function(){
    var getValue=$(this).val();
    alert(getValue);
  });

Note: In dropdownlist if you want to set id,text relation from your database then, set id as value in option tag, not by adding extra id attribute inside option its not standard paractise though i did both in my answer but i prefer example 1

HTML Markup

Example 1:
    <select id="example1">
        <option value="1">one</option>
        <option value="2">two</option>
        <option value="3">three</option>
        <option value="4">four</option>
    </select>
Example 2 :
    <select id="example2">
        <option id="1">one</option>
        <option id="2">two</option>
        <option id="3">three</option>
        <option id="4">four</option>
    </select>

Jquery:

$("#example1").on('change', function () {
    alert($(this).val());
});

$("#example2").on('change', function () {
    alert($(this).find('option:selected').attr('id'));

So .. quickest way is rename site config names ending in ".conf"

mv /etc/apache2/sites-available/mysite /etc/apache2/sites-available/mysite.conf

a2ensite mysite.conf

other notes on previous comments:

• IncludeOptional wasn't introduced until apache 2.36 - making change above followed by restart on 2.2 will leave your server down!

• also, version 2.2 a2ensite can't be hacked as described

as well, since your sites-available file is actually a configuration file, it should be named that way anyway..

In general do not restart services (webservers are one type of service):

• folks can't find them if they are not running! Think linux not MS Windows..

Servers can run for many years - live update, reload config, etc.

The cloud doesn't mean you have to restart to load a configuration file.

• When changing configuration of a service use "reload" not "restart".

• restart stops the service then starts service - if there is a any problem in your change to the config, the service will not restart.

• reload will give an error but the service never shuts down giving you a chance to fix the config error which could only be bad syntax.

debian or ubunto [service-name for this thread is apache2]

service {service-name} {start} {stop} {reload} ..

other os's left as an excersize for the reader.

In case someone is still looking for a solution for this, the following plugin does the job http://mohammadyounes.github.io/jquery-scrollLock/

It fully addresses the issue of locking mouse wheel scroll inside a given container, preventing it from propagating to parent element.

It does not change wheel scrolling speed, user experience will not be affected. and you get the same behavior regardless of the OS mouse wheel vertical scrolling speed (On Windows it can be set to one screen or one line up to 100 lines per notch).

If you're using .NET 3.5 or .NET 4, it's easy to create the dictionary using LINQ:

Dictionary<string, ArrayList> result = target.GetComponents()
                                      .ToDictionary(x => x.Key, x => x.Value);

There's no such thing as an IEnumerable<T1, T2> but a KeyValuePair<TKey, TValue> is fine.

On your servlet simply override the service method of your servlet so that you can add headers for all your http methods (POST, GET, DELETE, PUT, etc...).

@Override
    protected void service(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {

        if(("http://www.example.com").equals(req.getHeader("origin"))){
            res.setHeader("Access-Control-Allow-Origin", req.getHeader("origin"));
            res.setHeader("Access-Control-Allow-Headers", "Authorization");
        }

        super.service(req, res);
    }

Only, if they accept different parameters. If there are no parameters, then you must have different names.

int doSomething(String s);
String doSomething(int); // this is fine


int doSomething(String s);
String doSomething(String s); // this is not

I'm aware that I'm quite late for the party, but I consider that the library from Phillip Allan-Harding, it's the best one for this case and similar ones.

You only need a small piece of code like this one:

private const string LOGIN = "mamy";
private const string DOMAIN = "mongo";
private const string PASSWORD = "HelloMongo2017";

private void DBConnection()
{
    using (Impersonator user = new Impersonator(LOGIN, DOMAIN, PASSWORD, LogonType.LOGON32_LOGON_NEW_CREDENTIALS, LogonProvider.LOGON32_PROVIDER_WINNT50))
    {
    }
}

And add his class:

.NET (C#) Impersonation with Network Credentials

My example can be used if you require the impersonated logon to have network credentials, but it has more options.

You must have some virtual function declared in one of the parent classes and never implemented in any of the child classes. Make sure that all virtual functions are implemented somewhere in the inheritence chain. If a class's definition includes a pure virtual function that is never implemented, an instance of that class cannot ever be constructed.

eval is evil

eval("__import__('os').remove('important file')") # arbitrary commands
eval("9**9**9**9**9**9**9**9", {'__builtins__': None}) # CPU, memory

Note: even if you use set __builtins__ to None it still might be possible to break out using introspection:

eval('(1).__class__.__bases__[0].__subclasses__()', {'__builtins__': None})

        return operators[type(node.op)](eval_(node.operand))
    else:

You can easily limit allowed range for each operation or any intermediate result, e.g., to limit input arguments for a**b:

def power(a, b):
    if any(abs(n) > 100 for n in [a, b]):
        raise ValueError((a,b))
    return op.pow(a, b)
operators[ast.Pow] = power

Or to limit magnitude of intermediate results:

import functools

def limit(max_=None):
    """Return decorator that limits allowed returned values."""
    def decorator(func):
        @functools.wraps(func)
        def wrapper(*args, **kwargs):
            ret = func(*args, **kwargs)
            try:
                mag = abs(ret)
            except TypeError:
                pass # not applicable
            else:
                if mag > max_:
                    raise ValueError(ret)
            return ret
        return wrapper
    return decorator

eval_ = limit(max_=10**100)(eval_)

With VSCode you can find the merge conflicts easily with the following UI.

(if you do not have the topbar, set "editor.codeLens": true in User Preferences)

It indicates the current change that you have and incoming change from the server. This makes it easy to resolve the conflicts - just press the buttons above <<<< HEAD.

If you have multiple changes and want to apply all of them at once - open command palette (View -> Command Palette) and start typing merge - multiple options will appear including Merge Conflict: Accept Incoming, etc.

This should be tested in mysql, not postgresql:

You've got to use promises:

const asyncOperation = () => {
    return new Promise((resolve, reject) => {
        setTimeout(()=>{resolve("hi")}, 3000)
    })
}

const asyncFunction = async () => {
    return await asyncOperation();
}

const topDog = () => {
    asyncFunction().then((res) => {
        console.log(res);
    });
}

I like arrow function definitions more. But any string of the form "() => {...}" could also be written as "function () {...}"

So topDog is not async despite calling an async function.

EDIT: I realize a lot of the times you need to wrap an async function inside a sync function is inside a controller. For those situations, here's a party trick:

const getDemSweetDataz = (req, res) => {
    (async () => {
        try{
            res.status(200).json(
                await asyncOperation()
            );
        }
        catch(e){
            res.status(500).json(serviceResponse); //or whatever
        }
    })() //So we defined and immediately called this async function.
}

Utilizing this with callbacks, you can do a wrap that doesn't use promises:

const asyncOperation = () => {
    return new Promise((resolve, reject) => {
        setTimeout(()=>{resolve("hi")}, 3000)
    })
}

const asyncFunction = async (callback) => {
    let res = await asyncOperation();
    callback(res);
}

const topDog = () => {
    let callback = (res) => {
        console.log(res);
    };

    (async () => {
        await asyncFunction(callback)
    })()
}

By applying this trick to an EventEmitter, you can get the same results. Define the EventEmitter's listener where I've defined the callback, and emit the event where I called the callback.

Here is a solution using strings and converting it to decimal with ASCII tables:

#include <iostream>
#include <string>
#include "math.h"
using namespace std;
unsigned long hex2dec(string hex)
{
    unsigned long result = 0;
    for (int i=0; i<hex.length(); i++) {
        if (hex[i]>=48 && hex[i]<=57)
        {
            result += (hex[i]-48)*pow(16,hex.length()-i-1);
        } else if (hex[i]>=65 && hex[i]<=70) {
            result += (hex[i]-55)*pow(16,hex.length( )-i-1);
        } else if (hex[i]>=97 && hex[i]<=102) {
            result += (hex[i]-87)*pow(16,hex.length()-i-1);
        }
    }
    return result;
}

int main(int argc, const char * argv[]) {
    string hex_str;
    cin >> hex_str;
    cout << hex2dec(hex_str) << endl;
    return 0;
}

when you manually open the IP address (via the RUN command or mapping a network drive), your PC will send your credentials over the pipe and the file server will receive authorization from the DC.

When ASP.Net tries, then it is going to try to use the IIS worker user (unless impersonation is turned on which will list a few other issues). Traditionally, the IIS worker user does not have authorization to work across servers (or even in other folders on the web server).

You need to put the directory that has php.exe in you WAMP installation into your PATH. It is usually something like C:\wamp\xampp\php

You could also try wrapping the two div's in two div's with unique ids. Then select the div by $("#div1","#wraper1") and $("#div1","#wraper2")

Here you go:

<div id="wraper1">
<div id="div1">
</div>
<div id="wraper2">
<div id="div1">
</div>

You can delete a particular single line with its line number by

sed -i '33d' file

This will delete the line on 33 line number and save the updated file.

"The $.browser property is deprecated in jQuery 1.3, and its functionality may be moved to a team-supported plugin in a future release of jQuery."

From http://api.jquery.com/jQuery.browser/

Use a backslash as such

"From time to \"time\"";

Backslashes are used in PHP to escape special characters within quotes. As PHP does not distinguish between strings and characters, you could also use this

'From time to "time"';

The difference between single and double quotes is that double quotes allows for string interpolation, meaning that you can reference variables inline in the string and their values will be evaluated in the string like such

$name = 'Chris';
$greeting = "Hello my name is $name"; //equals "Hello my name is Chris"

As per your last edit of your question I think the easiest thing you may be able to do that this point is to use a 'heredoc.' They aren't commonly used and honestly I wouldn't normally recommend it but if you want a fast way to get this wall of text in to a single string. The syntax can be found here: http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc and here is an example:

$someVar = "hello";
$someOtherVar = "goodbye";
$heredoc = <<<term
This is a long line of text that include variables such as $someVar
and additionally some other variable $someOtherVar. It also supports having
'single quotes' and "double quotes" without terminating the string itself.
heredocs have additional functionality that most likely falls outside
the scope of what you aim to accomplish.
term;

app.controller('NavCtrl', function ($scope, $location, $state, $window, Post, Auth) {
    $scope.post = {url: 'http://', title: ''};

    $scope.createVariable = function(url) {
      $window.location.href = url;
    };
    $scope.createFixed = function() {
      $window.location.href = '/tab/newpost';
    };
});

HTML

<button class="button button-icon ion-compose" ng-click="createFixed()"></button>
<button class="button button-icon ion-compose" ng-click="createVariable('/tab/newpost')"></button>

You can use WhenAll which will return an awaitable Task or WaitAll which has no return type and will block further code execution simular to Thread.Sleep until all tasks are completed, canceled or faulted.

Example

var tasks = new Task[] {
    TaskOperationOne(),
    TaskOperationTwo()
};

Task.WaitAll(tasks);
// or
await Task.WhenAll(tasks);

If you want to run the tasks in a praticular order you can get inspiration form this anwser.

$_GET contains the keys / values that are passed to your script in the URL.

If you have the following URL :

http://www.example.com/test.php?a=10&b=plop

Then $_GET will contain :

array
  'a' => string '10' (length=2)
  'b' => string 'plop' (length=4)

Of course, as $_GET is not read-only, you could also set some values from your PHP code, if needed :

$_GET['my_value'] = 'test';

But this doesn't seem like good practice, as $_GET is supposed to contain data from the URL requested by the client.

Remove VALUES from your SQL.

CSS 3 introduces rgba colour, and you can combine it with graphics for a backwards compatible solution.

Look into twitter cards.

The trick is not in the button but rather the page you are sharing. Twitter Cards pull the image from the meta tags similar to facebook sharing.

Example:

<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@site_username">
<meta name="twitter:title" content="Top 10 Things Ever">
<meta name="twitter:description" content="Up than 200 characters.">
<meta name="twitter:creator" content="@creator_username">
<meta name="twitter:image" content="http://placekitten.com/250/250">
<meta name="twitter:domain" content="YourDomain.com">

If anyone is getting this error using Nginx, try adding the following to your server config:

server {
    listen 443 ssl;
    ...
}

The issue stems from Nginx serving an HTTP server to a client expecting HTTPS on whatever port you're listening on. When you specify ssl in the listen directive, you clear this up on the server side.

table_ages <- subset(infert, select=c("age"))
summary(table_ages)
#            age       
#  Min.   :21.00  
#  1st Qu.:28.00  
#  Median :31.00  
#  Mean   :31.50  
#  3rd Qu.:35.25  
#  Max.   :44.00  

This is probably what they're looking for. summary(...) applied to a numeric returns the min, max, mean, median, and 25th and 75th percentile of the data.

Note that

summary(infert$age)
#    Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
#   21.00   28.00   31.00   31.50   35.25   44.00 

The numbers are the same but the format is different. This is because table_ages is a data frame with one column (ages), whereas infert$age is a numeric vector. Try typing summary(infert).

Stop, stop, stop.

This is not how Vim's tabs are designed to be used. In fact, they're misnamed. A better name would be "viewport" or "layout", because that's what a tab is—it's a different layout of windows of all of your existing buffers.

Trying to beat Vim into 1 tab == 1 buffer is an exercise in futility. Vim doesn't know or care and it will not respect it on all commands—in particular, anything that uses the quickfix buffer (:make, :grep, and :helpgrep are the ones that spring to mind) will happily ignore tabs and there's nothing you can do to stop that.

Instead:

• :set hidden
  If you don't have this set already, then do so. It makes vim work like every other multiple-file editor on the planet. You can have edited buffers that aren't visible in a window somewhere.
• Use :bn, :bp, :b #, :b name, and ctrl-6 to switch between buffers. I like ctrl-6 myself (alone it switches to the previously used buffer, or #ctrl-6 switches to buffer number #).
• Use :ls to list buffers, or a plugin like MiniBufExpl or BufExplorer.

This worked for me fine:

File 1:

    <html>
    <head></head>
    <body>
        <a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
    </body>
    <footer></footer>
    </html>

File 2:

    <html>
        ...
    </html>

This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.

For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.

For anyone needs to change the options of the menu dynamically:

private Menu menu;

// ...

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    this.menu = menu;
    getMenuInflater().inflate(R.menu.options, menu);
    return true;
}

// ...

private void hideOption(int id)
{
    MenuItem item = menu.findItem(id);
    item.setVisible(false);
}

private void showOption(int id)
{
    MenuItem item = menu.findItem(id);
    item.setVisible(true);
}

private void setOptionTitle(int id, String title)
{
    MenuItem item = menu.findItem(id);
    item.setTitle(title);
}

private void setOptionIcon(int id, int iconRes)
{
    MenuItem item = menu.findItem(id);
    item.setIcon(iconRes);
}

you can use grid system without adding empty columns

<div class="col-xs-2 center-block" style="float:none"> ... </div>

change col-xs-2 to suit your layout.

if you have any problem with the library you can use Microsoft.Data.Sqlite;

 public static DataTable GetData(string connectionString, string query)
        {
            DataTable dt = new DataTable();
            Microsoft.Data.Sqlite.SqliteConnection connection;
            Microsoft.Data.Sqlite.SqliteCommand command;

            connection = new Microsoft.Data.Sqlite.SqliteConnection("Data Source= YOU_PATH_BD.sqlite");
            try
            {
                connection.Open();
                command = new Microsoft.Data.Sqlite.SqliteCommand(query, connection);
                dt.Load(command.ExecuteReader());
                connection.Close();
            }
            catch
            {
            }

            return dt;
        }

you can add NuGet Package Microsoft.Data.Sqlite

What does sourcing the bash script for?

1. If you intend to switch between multiple virtualenvs or enter one virtualenv quickly, have you tried virtualenvwrapper? It provides a lot of utils like workon venv, mkvirtualenv venv and so on.

2. If you just run a python script in certain virtualenv, use /path/to/venv/bin/python script.py to run it.

Load testing = putting a specified amount of load on the server for certain amount of time. 100 simultaneous users for 10 minutes. Ensure stability of software. Stress testing = increasing the amount of load steadily until the software crashes. 10 simultaneous users increasing every 2 minutes until the server crashes.

To make a comparison to weight lifting: You "max" your weight to see what you can do for 1 rep (stress testing) and then on regular workouts you do 85% of your max value for 3 sets of 10 reps (load testing)

$('.clickable').hover(function(){
      $('.selector').stop(true,true).fadeTo( 400 , 0.0, function() {
        $('.selector').css('background-image',"url('assets/img/pic2.jpg')");
        });
    $('.selector').fadeTo( 400 , 1);
},
function(){
      $('.selector').stop(false,true).fadeTo( 400 , 0.0, function() {
        $('.selector').css('background-image',"url('assets/img/pic.jpg')");
        });
    $('.selector').fadeTo( 400 , 1);
}

);

A better way is:

$("#element").val(null);

If you don't want to have to add the stop propagation to all links this works as well. A bit more scalable.

$scope.hideOverlay( $event ){

   // only hide the overlay if we click on the actual div
   if( $event.target.className.indexOf('overlay') ) 
      // hide overlay logic

}

Something like this will do it:

Rows("12:12").Select
Selection.Delete

So in your code it would look like something like this:

Rows(CStr(rand) & ":" & CStr(rand)).Select
Selection.Delete

To define a 3 column grid you could use the customizer or download the source set your less variables and recompile.

To learn more about the grid and the columns / gutter widths, please also read:

• Bootstrap 3 - Set Container Width to 940px Maximum for Desktops?
• Why does Bootstrap 3 force the container width to certain sizes?
• Bootstrap 3 Gutter Size
• Reduce the gutter (default 30px) on smaller devices in Bootstrap3?

In you case with a container of 960px consider the medium grid (see also: http://getbootstrap.com/css/#grid). This grid will have a max container width of 970px. When setting @grid-columns:3; and setting @grid-gutter-width:15px; in variables.less you will get:

15px | 1st column (298.33) | 15px | 2nd column (298.33) |15px | 3th column (298.33) | 15px

Why not just set the left two columns to a fixed with in your own css and then make a new grid layout of the full 12 columns for the rest of the content?

<div class="row">
    <div class="fixed-1">Left 1</div>
    <div class="fixed-2">Left 2</div>
    <div class="row">
        <div class="col-md-1"></div>
        <div class="col-md-11"></div>
    </div>
</div>

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

could be generated from simple code:

import javax.swing.*;
import javax.swing.table.*;

public class TableCheckBox extends JFrame {

    private static final long serialVersionUID = 1L;
    private JTable table;

    public TableCheckBox() {
        Object[] columnNames = {"Type", "Company", "Shares", "Price", "Boolean"};
        Object[][] data = {
            {"Buy", "IBM", new Integer(1000), new Double(80.50), false},
            {"Sell", "MicroSoft", new Integer(2000), new Double(6.25), true},
            {"Sell", "Apple", new Integer(3000), new Double(7.35), true},
            {"Buy", "Nortel", new Integer(4000), new Double(20.00), false}
        };
        DefaultTableModel model = new DefaultTableModel(data, columnNames);
        table = new JTable(model) {

            private static final long serialVersionUID = 1L;

            /*@Override

            @Override
            public Class getColumnClass(int column) {
                switch (column) {
                    case 0:
                        return String.class;
                    case 1:
                        return String.class;
                    case 2:
                        return Integer.class;
                    case 3:
                        return Double.class;
                    default:
                        return Boolean.class;
                }
            }
        };
        table.setPreferredScrollableViewportSize(table.getPreferredSize());
        JScrollPane scrollPane = new JScrollPane(table);
        getContentPane().add(scrollPane);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                TableCheckBox frame = new TableCheckBox();
                frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
                frame.pack();
                frame.setLocation(150, 150);
                frame.setVisible(true);
            }
        });
    }
}

The simplest way I manage to solve the issue was is by using a ZStack + .edgesIgnoringSafeArea(.all)

struct TestView : View {

    var body: some View {
        ZStack() {
            Color.yellow.edgesIgnoringSafeArea(.all)
            VStack {
                Text("Hello World")
            }
        }
    }
}

event.key === "Backspace"

More recent and much cleaner: use event.key. No more arbitrary number codes!

note.addEventListener('keydown', function(event) {
    const key = event.key; // const {key} = event; ES6+
    if (key === "Backspace") {
        // Do something
    }
});

Update

2020.06.14 I upgrade Chrome to 83.0 and above SO snippet stop works (due to sandbox security restrictions) - but JSFiddle version works - here

The way I've handled it so far: in UITextFieldDelegate

func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool
{
    // text hasn't changed yet, you have to compute the text AFTER the edit yourself
    let updatedString = (textField.text as NSString?)?.stringByReplacingCharactersInRange(range, withString: string)

    // do whatever you need with this updated string (your code)


    // always return true so that changes propagate
    return true
}

Swift4 version

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    let updatedString = (textField.text as NSString?)?.replacingCharacters(in: range, with: string)
    return true
}

I can't honestly see why one would not simply use typeof in this case:

if (typeof str === 'string') {
  return 42;
}

Yes it will fail against object-wrapped strings (e.g. new String('foo')) but these are widely regarded as a bad practice and most modern development tools are likely to discourage their use. (If you see one, just fix it!)

The Object.prototype.toString trick is something that all front-end developers have been found guilty of doing one day in their careers but don't let it fool you by its polish of clever: it will break as soon as something monkey-patch the Object prototype:

const isString = thing => Object.prototype.toString.call(thing) === '[object String]';_x000D_
_x000D_
console.log(isString('foo'));_x000D_
_x000D_
Object.prototype.toString = () => 42;_x000D_
_x000D_
console.log(isString('foo'));

The opening modes are exactly the same as those for the C standard library function fopen().

The BSD fopen manpage defines them as follows:

 The argument mode points to a string beginning with one of the following
 sequences (Additional characters may follow these sequences.):

 ``r''   Open text file for reading.  The stream is positioned at the
         beginning of the file.

 ``r+''  Open for reading and writing.  The stream is positioned at the
         beginning of the file.

 ``w''   Truncate file to zero length or create text file for writing.
         The stream is positioned at the beginning of the file.

 ``w+''  Open for reading and writing.  The file is created if it does not
         exist, otherwise it is truncated.  The stream is positioned at
         the beginning of the file.

 ``a''   Open for writing.  The file is created if it does not exist.  The
         stream is positioned at the end of the file.  Subsequent writes
         to the file will always end up at the then current end of file,
         irrespective of any intervening fseek(3) or similar.

 ``a+''  Open for reading and writing.  The file is created if it does not
         exist.  The stream is positioned at the end of the file.  Subse-
         quent writes to the file will always end up at the then current
         end of file, irrespective of any intervening fseek(3) or similar.

I had the same issue. Thanks for the answers above, I solved my issue. If there are people facing the same problem, here is two way to solve it:

• You can use {!! $news->body !!}
• You can use traditional php openning (It is not recommended) like: <?php echo $string ?>

I hope it helps.

ON I.object_id = OBJECT_ID('dbo.Expenses') AND 
IC.index_id = I.index_id
LEFT JOIN information_schema.columns ISC
ON ISC.TABLE_NAME = 'Expenses'
AND ISC.COLUMN_NAME = SC.name
WHERE SC.object_id = OBJECT_ID('dbo.Expenses')

Try this definitely work.

SELECT p.PersonID AS person_id,
   p.Name, p.SS, 
   f.FearID AS fear_id,
   f.Fear 
   FROM person_fear AS pf 
      LEFT JOIN persons AS p ON pf.PersonID = p.PersonID 
      LEFT JOIN fears AS f ON pf.PersonID = f.FearID 
   WHERE f.FearID = pf.FearID AND p.PersonID = pf.PersonID

To declare a string literal as an output column, leave the Table off and just use Test. It doesn't need to be associated with a table among your joins, since it will be accessed only by its column alias. When using a metadata function like getColumnMeta(), the table name will be an empty string because it isn't associated with a table.

SELECT
  `field1`, 
  `field2`, 
  'Test' AS `field3` 
FROM `Test`;

Note: I'm using single quotes above. MySQL is usually configured to honor double quotes for strings, but single quotes are more widely portable among RDBMS.

If you must have a table alias name with the literal value, you need to wrap it in a subquery with the same name as the table you want to use:

SELECT
  field1,
  field2,
  field3
FROM 
  /* subquery wraps all fields to put the literal inside a table */
  (SELECT field1, field2, 'Test' AS field3 FROM Test) AS Test

Now field3 will come in the output as Test.field3.

Found this answer here and wanted to reference it as it appear much cleaner than the accepted answer:

function blobToDataURL(blob, callback) {
  var fileReader = new FileReader();
  fileReader.onload = function(e) {callback(e.target.result);}
  fileReader.readAsDataURL(blob);
}

This is due to spring-config.xml is not in classpath.

Add complete path of spring-config.xml to your classpath.

Also write command you execute to run your project. You can check classpath in command.

I just ran into a similar issue. When I changed my script reference from self-closing tags (ie, <script src=".." />) to empty nodes (ie, <script src=".."></script>) my errors went away and I could suddenly reference the jQuery UI functions.

At the time, I didn't realize this was just a brain-fart of me not closing it properly to begin with. (I'm posting this simply on the chance that anyone else coming across the thread is having a similar issue.)

I've wrote a small extension to do so.

Since you are creating the page using C# you may want to implement this:

https://github.com/felix-d-git/DesktopAppLink

Basically u are creating some registry entries to parse the links you click in your html page.

The browser will then ask to open the specified app.

C#:

DesktopAppLink.CreateLink("applink.sample", "\"<path to exe>\"", "");

HTML:

<a href="applink.sample:">Run Desktop App</a>

Result:

You can store favourites with no associated menu in a separate table:

CREATE TABLE FavoriteWithoutMenu
(
  FavoriteWithoutMenuId uuid NOT NULL, --Primary key
  UserId uuid NOT NULL,
  RecipeId uuid NOT NULL,
  UNIQUE KEY (UserId, RecipeId)
)

Here's a quick and easy method:

CREATE TABLE database1.employees
AS
SELECT * FROM database2.employees;

Or you can just use commands.getstatusoutput:

   commands.getstatusoutput("ssh machine 1 'your script'")

I used it extensively and it works great.

In Python 2.6+, use subprocess.check_output.

I made my own version here : http://androidblogger.blogspot.com/2009/12/how-to-improve-your-application-crash.html

It's basically the same thing, but I'm using a mail rather than a http connexion to send the report, and, more important, I added some informations like application version, OS version, Phone model, or avalaible memory to my report...

To give an example to what Alex said, if you're using Magento, for example, .phtml files are only to be found in the /design area as template files, and contain both HTML and PHP lines. Meanwhile the PHP files are pure code and don't have any lines of HTML in them.

Maps from JDK are not meant for storing data under duplicated keys.

• At best new value will override the previous ones.

• Worse scenario is exception (e.g when you try to collect it as a stream):

No duplicates:

Stream.of("one").collect(Collectors.toMap(x -> x, x -> x))

Ok. You will get: $2 ==> {one=one}

Duplicated stream:

Stream.of("one", "not one", "surely not one").collect(Collectors.toMap(x -> 1, x -> x))

Exception java.lang.IllegalStateException: Duplicate key 1 (attempted merging values one and not one) | at Collectors.duplicateKeyException (Collectors.java:133) | at Collectors.lambda$uniqKeysMapAccumulator$1 (Collectors.java:180) | at ReduceOps$3ReducingSink.accept (ReduceOps.java:169) | at Spliterators$ArraySpliterator.forEachRemaining (Spliterators.java:948) | at AbstractPipeline.copyInto (AbstractPipeline.java:484) | at AbstractPipeline.wrapAndCopyInto (AbstractPipeline.java:474) | at ReduceOps$ReduceOp.evaluateSequential (ReduceOps.java:913) | at AbstractPipeline.evaluate (AbstractPipeline.java:234) | at ReferencePipeline.collect (ReferencePipeline.java:578) | at (#4:1)

To deal with duplicated keys - use other package, e.g: https://google.github.io/guava/releases/19.0/api/docs/com/google/common/collect/Multimap.html

There is a lot of other implementations dealing with duplicated keys. Those are needed for web (e.g. duplicated cookie keys, Http headers can have same fields, ...)

Good luck! :)

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

I followed steps in below link - https://medium.com/@euedofia/fix-default-java-version-on-maven-on-mac-os-x-156cf5930078 and it worked for me.

nano mvn
--Update JAVA_HOME -> "${JAVA_HOME:-$(/usr/libexec/java_home)}"
mvn -version

as far as i can remember, you need to use a HTTP CONNECT query on the proxy. this will convert the request connection to a transparent TCP/IP tunnel.

so you need to know if the proxy server you use support this protocol.

just use iFrame for PDF's.

I had specific needs in my React.js app, tried millions of solutions but ended up with an iFrame :) Good luck!

When you refer the chart to a defined Range, it plots all the points in that range, interpreting (for the sake of plotting) errors and blanks as null values.

You are given the option of leaving this as null (gap) or forcing it to zero value. But neither of these resizes the RANGE which the chart series data is pointing to. From what I gather, neither of these are suitable.

If you hide the entire row/column where the #N/A data exists, the chart should ignore these completely. You can do this manually by right-click | hide row, or by using the table AutoFilter. I think this is what you want to accomplish.

The accepted answer doesn't support Azure. It uses an undocumented stored procedure "sp_MSforeachtable". If you get an "azure could not find stored procedure 'sp_msforeachtable" error when running or simply want to avoid relying on undocumented features (which can be removed or have their functionality changed at any point) then try the below.

This version ignores the entity framework migration history table "__MigrationHistory" and the "database_firewall_rules" which is an Azure table you will not have permission to delete.

Lightly tested on Azure. Do check to make this this has no undesired effects on your environment.

To plot multiple graphs on the same figure you will have to do:

from numpy import *
import math
import matplotlib.pyplot as plt

t = linspace(0, 2*math.pi, 400)
a = sin(t)
b = cos(t)
c = a + b

plt.plot(t, a, 'r') # plotting t, a separately 
plt.plot(t, b, 'b') # plotting t, b separately 
plt.plot(t, c, 'g') # plotting t, c separately 
plt.show()

You would need to lower your gradle version and android plugin version, or you can download latest version from beta or canary update channels.

To enable updates from other channels go to Help -> Check for Updates -> Congifure automatic updates and in that dialog select channel you want. After selecting check for update again and it will show you latest version.

Important Note: Alert of Future Deprecation.

As of iOS 9.0, the API functions description for:

AudioServicesPlaySystemSound(inSystemSoundID: SystemSoundID)
AudioServicesPlayAlertSound(inSystemSoundID: SystemSoundID)

includes the following note:

This function will be deprecated in a future release.
Use AudioServicesPlayAlertSoundWithCompletion or  
AudioServicesPlaySystemSoundWithCompletion instead.

The right way to go will be using any of these two:

AudioServicesPlayAlertSoundWithCompletion(kSystemSoundID_Vibrate, nil)

or

AudioServicesPlayAlertSoundWithCompletion(kSystemSoundID_Vibrate) {
 //your callback code when the vibration is done (it may not vibrate in iPod, but this callback will be always called)
}

remember to import AVFoundation

Actually, even if your variable (SongLength) is numeric, you will still have to format it with %s in order to bind the parameter correctly. If you try to use %d, you will get an error. Here's a small excerpt from this link http://mysql-python.sourceforge.net/MySQLdb.html:

To perform a query, you first need a cursor, and then you can execute queries on it:

c=db.cursor()
max_price=5
c.execute("""SELECT spam, eggs, sausage FROM breakfast
          WHERE price < %s""", (max_price,))

In this example, max_price=5 Why, then, use %s in the string? Because MySQLdb will convert it to a SQL literal value, which is the string '5'. When it's finished, the query will actually say, "...WHERE price < 5".

I'm positive it would require SMTP authentication credentials as well.

According to wikipedia, it means a "double colon" scope resolution operator.

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

The list may contain several elements, so the get method takes an argument : the index of the element you want to retrieve. If you want the first one, then it's 0.

The list contains Car instances, so you just have to do

Car firstCar = car.get(0);
String price = firstCar.getPrice();

or just

String price = car.get(0).getPrice();

The car variable should be named cars, since it's a list and thus contains several cars.

Read the tutorial about collections. And learn to use the javadoc: all the classes and methods are documented.

SQL Server doesn't have regular expressions. It uses the LIKE pattern matching syntax which isn't the same.

As it happens, you are close. Just need leading+trailing wildcards and move the NOT

 WHERE whatever NOT LIKE '%[a-z0-9]%'

Using Go to File... which is under the Go menu or using keyboard shortcut:

• On Windows Ctrl+p or Ctrl+e
• On macOS Cmd ?+p
• On Linux Ctrl+p or Ctrl+e

Then type the file name.

Also be sure to checkout that you can set your own keybindings and that there are cheatsheets available for Windows, macOS and Linux.

Hibernate, because it:

• is stable - being around for so many years, it lacks any major problems
• dictates the standards in the ORM field
• implements the standard (JPA), in addition to dictating it.
• has tons of information about it on the Internet. There are many tutorials, common problem solutions, etc
• is powerful - you can translate a very complex object model into a relational model.
• it has support for any major and medium RDBMS
• is easy to work with, once you learn it well

A few points on why (and when) to use ORM:

• you work with objects in your system (if your system has been designed well). Even if using JDBC, you will end up making some translation layer, so that you transfer your data to your objects. But my bets are that hibernate is better at translation than any custom-made solution.
• it doesn't deprive you of control. You can control things in very small details, and if the API doesn't have some remote feature - execute a native query and you have it.
• any medium-sized or bigger system can't afford having one ton of queries (be it at one place or scattered across), if it aims to be maintainable
• if performance isn't critical. Hibernate adds performance overhead, which in some cases can't be ignored.

Store it in a cookie that only lasts for the current browsing session

My solution:

Create a function script that is called earlier than all other functions without passing any arguments to it, like this:

! /bin/bash

function init(){ ORIGOPT= "- $@ -" }

Afer that, you can call init and use the ORIGOPT var as needed,as a plus, I always assign a new var and copy the contents of ORIGOPT in my new functions, that way you can keep yourself assured nobody is going to touch it or change it.

I added spaces and dashes to make it easier to parse it with 'sed -E' also bash will not pass it as reference and make ORIGOPT grow as functions are called with more arguments.

For those who must solve this problem using Oracle 9i (or earlier), you will probably need to use SYS_CONNECT_BY_PATH, since LISTAGG is not available.

To answer the OP, the following query will display the PID from Table A and concatenate all the DESC columns from Table B:

SELECT pid, SUBSTR (MAX (SYS_CONNECT_BY_PATH (description, ', ')), 3) all_descriptions
FROM (
       SELECT ROW_NUMBER () OVER (PARTITION BY pid ORDER BY pid, seq) rnum, pid, description
       FROM (
              SELECT a.pid, seq, description
              FROM table_a a, table_b b
              WHERE a.pid = b.pid(+)
             )
      )
START WITH rnum = 1
CONNECT BY PRIOR rnum = rnum - 1 AND PRIOR pid = pid
GROUP BY pid
ORDER BY pid;

There may also be instances where keys and values are all contained in one table. The following query can be used where there is no Table A, and only Table B exists:

SELECT pid, SUBSTR (MAX (SYS_CONNECT_BY_PATH (description, ', ')), 3) all_descriptions
FROM (
       SELECT ROW_NUMBER () OVER (PARTITION BY pid ORDER BY pid, seq) rnum, pid, description
       FROM (
              SELECT pid, seq, description
              FROM table_b
             )
      )
START WITH rnum = 1
CONNECT BY PRIOR rnum = rnum - 1 AND PRIOR pid = pid
GROUP BY pid
ORDER BY pid;

All values can be reordered as desired. Individual concatenated descriptions can be reordered in the PARTITION BY clause, and the list of PIDs can be reordered in the final ORDER BY clause.

Alternately: there may be times when you want to concatenate all the values from an entire table into one row.

The key idea here is using an artificial value for the group of descriptions to be concatenated.

In the following query, the constant string '1' is used, but any value will work:

SELECT SUBSTR (MAX (SYS_CONNECT_BY_PATH (description, ', ')), 3) all_descriptions
FROM (
       SELECT ROW_NUMBER () OVER (PARTITION BY unique_id ORDER BY pid, seq) rnum, description
       FROM (
              SELECT '1' unique_id, b.pid, b.seq, b.description
              FROM table_b b
             )
      )
START WITH rnum = 1
CONNECT BY PRIOR rnum = rnum - 1;

Individual concatenated descriptions can be reordered in the PARTITION BY clause.

2) If the client create the csv from excel then the data that have comma are enclosed within " ... " (double quotes) [as the below example] so how do the import can handle this?

You should use FORMAT = 'CSV', FIELDQUOTE = '"' options:

You can set the default like this:

b = models.CharField(max_length=7,default="foobar")

and then you can hide the field with your model's Admin class like this:

class SomeModelAdmin(admin.ModelAdmin):
    exclude = ("b")

gradle supports ndk compilation by generating another Android.mk file with absolute paths to your sources. NDK supports absolute paths since r9 on OSX, r9c on Windows, so you need to upgrade your NDK to r9+.

You may run into other troubles as NDK support by gradle is preliminary. If so you can deactivate the ndk compilation from gradle by setting:

sourceSets.main {
    jni.srcDirs = []
    jniLibs.srcDir 'src/main/libs'
}

to be able to call ndk-build yourself and integrate libs from libs/.

btw, you have any issue compiling for x86 ? I see you haven't included it in your APP_ABI.

The lean option tells Mongoose to skip hydrating the result documents. This makes queries faster and less memory intensive, but the result documents are plain old JavaScript objects (POJOs), not Mongoose documents.

const leanDoc = await MyModel.findOne().lean();

not necessary to use JSON.parse() method

Simple but works like a charm.

$("#form").trigger('reset'); //jquery
document.getElementById("myform").reset(); //native JS

You can use either Picasso or Glide.

Picasso.with(context)
   .load(your_url)
   .into(imageView);


Glide.with(context)
   .load(your_url)
   .into(imageView);

Initially, the result set object (rs) points to the BFR (before first record). Once we use rs.next(), the cursor points to the first record and the rs holds "true". Using the while loop you can print all the records of the table. After all the records are retrieved, the cursor moves to ALR (After last record) and it will be set to null. Let us consider that there are 2 records in the table.

if(rs.next()==false){
    // there are no records found
    }    

while (rs.next()==true){
    // print all the records of the table
    }

In short hand, we can also write the condition as while (rs.next()).

I have always thought the different between RDL and RDLC is that RDL are used for SQL Server Reporting Services and RDLC are used in Visual Studio for client side reporting. The implemenation and editor are almost identical. RDL stands for Report Defintion Language and RDLC Report Definition Language Client-side.

I hope that helps.

  String dateTime="15-3-2019 09:50 AM" //time should be two digit like 08,09,10

        LocalDateTime zdt  = LocalDateTime.parse(dateTime,dtf);
        LocalDateTime now = LocalDateTime.now();
        ZoneId zone = ZoneId.of("Asia/Kolkata");

The PostgreSQL manual indicates that this means the transaction is open (inside BEGIN) and idle. It's most likely a user connected using the monitor who is thinking or typing. I have plenty of those on my system, too.

If you're using Slony for replication, however, the Slony-I FAQ suggests idle in transaction may mean that the network connection was terminated abruptly. Check out the discussion in that FAQ for more details.

BehaviourSubject

BehaviourSubject will return the initial value or the current value on Subscription

var bSubject= new Rx.BehaviorSubject(0);  // 0 is the initial value

bSubject.subscribe({
  next: (v) => console.log('observerA: ' + v)  // output initial value, then new values on `next` triggers
});

bSubject.next(1);  // output new value 1 for 'observer A'
bSubject.next(2);  // output new value 2 for 'observer A', current value 2 for 'Observer B' on subscription

bSubject.subscribe({
  next: (v) => console.log('observerB: ' + v)  // output current value 2, then new values on `next` triggers
});

bSubject.next(3);

With output:

observerA: 0
observerA: 1
observerA: 2
observerB: 2
observerA: 3
observerB: 3

Subject

Subject does not return the current value on Subscription. It triggers only on .next(value) call and return/output the value

var subject = new Rx.Subject();

subject.next(1); //Subjects will not output this value

subject.subscribe({
  next: (v) => console.log('observerA: ' + v)
});
subject.subscribe({
  next: (v) => console.log('observerB: ' + v)
});

subject.next(2);
subject.next(3);

With the following output on the console:

observerA: 2
observerB: 2
observerA: 3
observerB: 3

Here is an approach that doesn't require the use of a for loop or defining an intermediate function or lambda function (and is also a one-liner). The method combines the following two ideas:

• calling the iter() built-in function with the optional sentinel argument, and

• using the itertools recipe for advancing an iterator n steps (see the recipe for consume()).

Putting these together, we get:

next(islice(iter(do, object()), 3, 3), None)

(The idea to pass object() as the sentinel comes from this accepted Stack Overflow answer.)

And here is what this looks like from the interactive prompt:

>>> def do():
...   print("called")
... 
>>> next(itertools.islice(iter(do, object()), 3, 3), None)
called
called
called

Using the cursor based variations above as a starting point, the script below will just output a set of UPDATE statements to set to DATABASE_DEFAULT, it won't actually do the UPDATES.

It supports schema, the full set of char and text types and retains the existing NULL / NOT NULL.

I plan to use the output to find to statements that fail in a lower environment and then manually adapt the resulting script to drop and recreate the constraints as needed.

You need to apply the following CSS property to the container block (div):

overflow-wrap: break-word;

According to the specifications (source CSS | MDN):

The overflow-wrap CSS property specifies whether or not the browser should insert line breaks within words to prevent text from overflowing its content box.

With the value set to break-word

To prevent overflow, normally unbreakable words may be broken at arbitrary points if there are no otherwise acceptable break points in the line.

Worth mentioning...

The property was originally a nonstandard and unprefixed Microsoft extension called word-wrap, and was implemented by most browsers with the same name. It has since been renamed to overflow-wrap, with word-wrap being an alias.

If you care about legacy browsers support it's worth specifying both:

word-wrap    : break-word;
overflow-wrap: break-word;

Ex. IE9 does not recognize overflow-wrap but works fine with word-wrap

I do this a lot, and I don't have an insert key on my laptop, so I made my own keybinding for it. You can do this by opening Settings > IDE Settings > Keymap and navigating to Main menu > File > New... (I would recommend typing "new" into the search box - that will narrow it down considerably).

Then you can add a new keyboard shortcut for it by double clicking on that item and selecting Add Keyboard Shortcut.

You can't style the drop down box itself, only the input field. The box is rendered by the operating system.

If you want more control over the look of your input fields, you can always look into JavaScript solutions.

If, however, your intent was to remove the border from the input itself, your selector is wrong. Try this instead:

select#xyz {
    border: none;
}

res.setHeader('Access-Control-Allow-Headers', '*');

With VS 2010, use the Database project.

Change .img-responsive inside bootstrap.css to the following:

.img-responsive {
    display: block;
    max-width: 100%;
    width: 100%;
    height: auto;
}

For some reason adding width: 100% to the mix makes img-responsive work.

This library: Android-Image-Cropper is very powerful to CropImages. It has 3,731 stars on github at this time.

You will crop your images with a few lines of code.

1 - Add the dependecies into buid.gradle (Module: app)

compile 'com.theartofdev.edmodo:android-image-cropper:2.7.+'

2 - Add the permissions into AndroidManifest.xml

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

3 - Add CropImageActivity into AndroidManifest.xml

<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
 android:theme="@style/Base.Theme.AppCompat"/>

4 - Start the activity with one of the cases below, depending on your requirements.

// start picker to get image for cropping and then use the image in cropping activity
CropImage.activity()
.setGuidelines(CropImageView.Guidelines.ON)
.start(this);

// start cropping activity for pre-acquired image saved on the device
CropImage.activity(imageUri)
.start(this);

// for fragment (DO NOT use `getActivity()`)
CropImage.activity()
.start(getContext(), this);

5 - Get the result in onActivityResult

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
  if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
    CropImage.ActivityResult result = CropImage.getActivityResult(data);
    if (resultCode == RESULT_OK) {
      Uri resultUri = result.getUri();
    } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
      Exception error = result.getError();
    }
  }
}

You can do several customizations, as set the Aspect Ratio or the shape to RECTANGLE, OVAL and a lot more.

My understanding of marshalling is different to the other answers.

Serialization:

To Produce or rehydrate a wire-format version of an object graph utilizing a convention.

Marshalling:

To Produce or rehydrate a wire-format version of an object graph by utilizing a mapping file, so that the results can be customized. The tool may start by adhering to a convention, but the important difference is the ability to customize results.

Contract First Development:

Marshalling is important within the context of contract first development.

• Its possible to make changes to an internal object graph, while keeping the external interface stable over time. This way all of the service subscribers won't have to be modified for every trivial change.
• Its possible to map the results across different languages. For example from the property name convention of one language ('property_name') to another ('propertyName').

If you are using reactiveFormModule and have formGroup defined like this:

public exampleForm = new FormGroup({
        name: new FormControl('Test name', [Validators.required, Validators.minLength(3)]),
        email: new FormControl('[email protected]', [Validators.required, Validators.maxLength(50)]),
        age: new FormControl(45, [Validators.min(18), Validators.max(65)])
});

than you are able to add a new validator (and keep old ones) to FormControl with this approach:

this.exampleForm.get('age').setValidators([
        Validators.pattern('^[0-9]*$'),
        this.exampleForm.get('age').validator
]);
this.exampleForm.get('email').setValidators([
        Validators.email,
        this.exampleForm.get('email').validator
]);

FormControl.validator returns a compose validator containing all previously defined validators.

Scikit learn plays really well with Pandas, so I suggest you use it. Here's an example:

In [1]: 
import pandas as pd
import numpy as np
from sklearn.model_selection import train_test_split
data = np.reshape(np.random.randn(20),(10,2)) # 10 training examples
labels = np.random.randint(2, size=10) # 10 labels

In [2]: # Giving columns in X a name
X = pd.DataFrame(data, columns=['Column_1', 'Column_2'])
y = pd.Series(labels)

In [3]:
X_train, X_test, y_train, y_test = train_test_split(X, y, 
                                                    test_size=0.2, 
                                                    random_state=0)

In [4]: X_test
Out[4]:

     Column_1    Column_2
2   -1.39       -1.86
8    0.48       -0.81
4   -0.10       -1.83

In [5]: y_test
Out[5]:

2    1
8    1
4    1
dtype: int32

You can directly call any scikit functions on DataFrame/Series and it will work.

Let's say you wanted to do a LogisticRegression, here's how you could retrieve the coefficients in a nice way:

In [6]: 
from sklearn.linear_model import LogisticRegression

model = LogisticRegression()
model = model.fit(X_train, y_train)

# Retrieve coefficients: index is the feature name (['Column_1', 'Column_2'] here)
df_coefs = pd.DataFrame(model.coef_[0], index=X.columns, columns = ['Coefficient'])
df_coefs
Out[6]:
            Coefficient
Column_1    0.076987
Column_2    -0.352463

If you came here from Google, trying to find where your previously created virtualenv installation ended up, and why there is no command to find it, here's the low-down.

The design of virtualenv has a fundamental flaw of not being able to keep track of it's own created environments. Someone was not quite in their right mind when they created virtualenv without having a rudimentary way to keep track of already created environments, and certainly not fit for a time and age when most pip requirements require multi-giga-byte installations, which should certainly not go into some obscure .virtualenvs sub-directory of your ~/home.

IMO, the created virtualenv directory should be created in $CWD and a file called ~/.virtualenv (in home) should keep track of the name and path of that creation. Which is a darn good reason to use Conda/Miniconda3 instead, which does seem to keep good track of this.

As answered here, the only way to keep track of this, is to install yet another package called virtualenvwrapper. If you don't do that, you will have to search for the created directory by yourself. Clearly, if you don't remember the name or the location it was created with/at, you will most likely never find your virtual environment again...

One try to remedy the situation in windows, is by putting the following functions into your powershell profile:

# wrap virtualenv.exe and write last argument (presumably 
# your virtualenv name) to the file: $HOME/.virtualenv.
function ven { if( $args.count -eq 0) {Get-Content ~/.virtualenv } else {virtualenv.exe "$args"; Write-Output ("{0} `t{1}" -f $args[-1],$PWD) | Out-File -Append $HOME/.virtualenv }}

# List what's in the file or the directories under ~/.virtualenvs
function lsven { try {Get-Content ~/.virtualenv } catch {Get-ChildItem ~\.virtualenvs -Directory | Select-Object -Property Name } }

_{WARNING: This will write to ~\.virtualenv...}

Our example project has two build targets: HelloWorld.app and Helper.app. We make a component package for each and combine them into a product archive.

A component package contains payload to be installed by the OS X Installer. Although a component package can be installed on its own, it is typically incorporated into a product archive.

Our tools: pkgbuild, productbuild, and pkgutil

After a successful "Build and Archive" open $BUILT_PRODUCTS_DIR in the Terminal.

$ cd ~/Library/Developer/Xcode/DerivedData/.../InstallationBuildProductsLocation
$ pkgbuild --analyze --root ./HelloWorld.app HelloWorldAppComponents.plist
$ pkgbuild --analyze --root ./Helper.app HelperAppComponents.plist

This give us the component-plist, you find the value description in the "Component Property List" section. pkgbuild -root generates the component packages, if you don't need to change any of the default properties you can omit the --component-plist parameter in the following command.

productbuild --synthesize results in a Distribution Definition.

$ pkgbuild --root ./HelloWorld.app \
    --component-plist HelloWorldAppComponents.plist \
    HelloWorld.pkg
$ pkgbuild --root ./Helper.app \
    --component-plist HelperAppComponents.plist \
    Helper.pkg
$ productbuild --synthesize \
    --package HelloWorld.pkg --package Helper.pkg \
    Distribution.xml 

In the Distribution.xml you can change things like title, background, welcome, readme, license, and so on. You turn your component packages and distribution definition with this command into a product archive:

$ productbuild --distribution ./Distribution.xml \
    --package-path . \
    ./Installer.pkg

I recommend to take a look at iTunes Installers Distribution.xml to see what is possible. You can extract "Install iTunes.pkg" with:

$ pkgutil --expand "Install iTunes.pkg" "Install iTunes"

Lets put it together

I usually have a folder named Package in my project which includes things like Distribution.xml, component-plists, resources and scripts.

Add a Run Script Build Phase named "Generate Package", which is set to Run script only when installing:

VERSION=$(defaults read "${BUILT_PRODUCTS_DIR}/${FULL_PRODUCT_NAME}/Contents/Info" CFBundleVersion)

PACKAGE_NAME=`echo "$PRODUCT_NAME" | sed "s/ /_/g"`
TMP1_ARCHIVE="${BUILT_PRODUCTS_DIR}/$PACKAGE_NAME-tmp1.pkg"
TMP2_ARCHIVE="${BUILT_PRODUCTS_DIR}/$PACKAGE_NAME-tmp2"
TMP3_ARCHIVE="${BUILT_PRODUCTS_DIR}/$PACKAGE_NAME-tmp3.pkg"
ARCHIVE_FILENAME="${BUILT_PRODUCTS_DIR}/${PACKAGE_NAME}.pkg"

pkgbuild --root "${INSTALL_ROOT}" \
    --component-plist "./Package/HelloWorldAppComponents.plist" \
    --scripts "./Package/Scripts" \
    --identifier "com.test.pkg.HelloWorld" \
    --version "$VERSION" \
    --install-location "/" \
    "${BUILT_PRODUCTS_DIR}/HelloWorld.pkg"
pkgbuild --root "${BUILT_PRODUCTS_DIR}/Helper.app" \
    --component-plist "./Package/HelperAppComponents.plist" \
    --identifier "com.test.pkg.Helper" \
    --version "$VERSION" \
    --install-location "/" \
    "${BUILT_PRODUCTS_DIR}/Helper.pkg"
productbuild --distribution "./Package/Distribution.xml"  \
    --package-path "${BUILT_PRODUCTS_DIR}" \
    --resources "./Package/Resources" \
    "${TMP1_ARCHIVE}"

pkgutil --expand "${TMP1_ARCHIVE}" "${TMP2_ARCHIVE}"
    
# Patches and Workarounds

pkgutil --flatten "${TMP2_ARCHIVE}" "${TMP3_ARCHIVE}"

productsign --sign "Developer ID Installer: John Doe" \
    "${TMP3_ARCHIVE}" "${ARCHIVE_FILENAME}"

If you don't have to change the package after it's generated with productbuild you could get rid of the pkgutil --expand and pkgutil --flatten steps. Also you could use the --sign paramenter on productbuild instead of running productsign.

Sign an OS X Installer

Packages are signed with the Developer ID Installer certificate which you can download from Developer Certificate Utility.

They signing is done with the --sign "Developer ID Installer: John Doe" parameter of pkgbuild, productbuild or productsign.

Note that if you are going to create a signed product archive using productbuild, there is no reason to sign the component packages.

All the way: Copy Package into Xcode Archive

To copy something into the Xcode Archive we can't use the Run Script Build Phase. For this we need to use a Scheme Action.

Edit Scheme and expand Archive. Then click post-actions and add a New Run Script Action:

In Xcode 6:

#!/bin/bash

PACKAGES="${ARCHIVE_PATH}/Packages"
  
PACKAGE_NAME=`echo "$PRODUCT_NAME" | sed "s/ /_/g"`
ARCHIVE_FILENAME="$PACKAGE_NAME.pkg"
PKG="${OBJROOT}/../BuildProductsPath/${CONFIGURATION}/${ARCHIVE_FILENAME}"

if [ -f "${PKG}" ]; then
    mkdir "${PACKAGES}"
    cp -r "${PKG}" "${PACKAGES}"
fi

In Xcode 5, use this value for PKG instead:

PKG="${OBJROOT}/ArchiveIntermediates/${TARGET_NAME}/BuildProductsPath/${CONFIGURATION}/${ARCHIVE_FILENAME}"

In case your version control doesn't store Xcode Scheme information I suggest to add this as shell script to your project so you can simple restore the action by dragging the script from the workspace into the post-action.

Scripting

There are two different kinds of scripting: JavaScript in Distribution Definition Files and Shell Scripts.

The best documentation about Shell Scripts I found in WhiteBox - PackageMaker How-to, but read this with caution because it refers to the old package format.

Apple Silicon

In order for the package to run as arm64, the Distribution file has to specify in its hostArchitectures section that it supports arm64 in addition to x86_64:

<options hostArchitectures="arm64,x86_64" />

Known Issues and Workarounds

Destination Select Pane

The user is presented with the destination select option with only a single choice - "Install for all users of this computer". The option appears visually selected, but the user needs to click on it in order to proceed with the installation, causing some confusion.

Apples Documentation recommends to use <domains enable_anywhere ... /> but this triggers the new more buggy Destination Select Pane which Apple doesn't use in any of their Packages.

Using the deprecate <options rootVolumeOnly="true" /> give you the old Destination Select Pane.

You want to install items into the current user’s home folder.

Short answer: DO NOT TRY IT!

Long answer: REALLY; DO NOT TRY IT! Read Installer Problems and Solutions. You know what I did even after reading this? I was stupid enough to try it. Telling myself I'm sure that they fixed the issues in 10.7 or 10.8.

First of all I saw from time to time the above mentioned Destination Select Pane Bug. That should have stopped me, but I ignored it. If you don't want to spend the week after you released your software answering support e-mails that they have to click once the nice blue selection DO NOT use this.

You are now thinking that your users are smart enough to figure the panel out, aren't you? Well here is another thing about home folder installation, THEY DON'T WORK!

I tested it for two weeks on around 10 different machines with different OS versions and what not, and it never failed. So I shipped it. Within an hour of the release I heart back from users who just couldn't install it. The logs hinted to permission issues you are not gonna be able to fix.

So let's repeat it one more time: We do not use the Installer for home folder installations!

RTFD for Welcome, Read-me, License and Conclusion is not accepted by productbuild.

Installer supported since the beginning RTFD files to make pretty Welcome screens with images, but productbuild doesn't accept them.

Workarounds: Use a dummy rtf file and replace it in the package by after productbuild is done.

Note: You can also have Retina images inside the RTFD file. Use multi-image tiff files for this: tiffutil -cat Welcome.tif Welcome_2x.tif -out FinalWelcome.tif. More details.

Starting an application when the installation is done with a BundlePostInstallScriptPath script:

#!/bin/bash

LOGGED_IN_USER_ID=`id -u "${USER}"`

if [ "${COMMAND_LINE_INSTALL}" = "" ]
then
    /bin/launchctl asuser "${LOGGED_IN_USER_ID}" /usr/bin/open -g PATH_OR_BUNDLE_ID
fi

exit 0

It is important to run the app as logged in user, not as the installer user. This is done with launchctl asuser uid path. Also we only run it when it is not a command line installation, done with installer tool or Apple Remote Desktop.

Your selector for the .show() and .hide() are not pointing to anything in the code.

neither try any above ways nor sudo apt autoremove python3 because it will remove all gnome based applications from your system including gnome-terminal. In case if you have done that mistake and left with kernal only than trysudo apt install gnome on kernal.

try to change your default python version instead removing it. you can do this through bashrc file or export path command.

Using ERRORLEVEL when it's available is the easiest option. However, if you're calling an external program to perform some task, and it doesn't return proper codes, you can pipe the output to 'find' and check the errorlevel from that.

c:\mypath\myexe.exe | find "ERROR" >nul2>nul
if not ERRORLEVEL 1 (
echo. Uh oh, something bad happened
exit /b 1
)

Or to give more info about what happened

c:\mypath\myexe.exe 2&1> myexe.log
find "Invalid File" "myexe.log" >nul2>nul && echo.Invalid File error in Myexe.exe && exit /b 1
find "Error 0x12345678" "myexe.log" >nul2>nul && echo.Myexe.exe was unable to contact server x && exit /b 1

You cannot session_start(); when your buffer has already been partly sent.

This mean, if your script already sent informations (something you want, or an error report) to the client, session_start() will fail.

You don't really need jQuery for this as there is a Media API that provides you with all you need.

var video = document.getElementById('myVideo');
video.src = 'my_video_' + value + '.ogg';
video.load();

The Media API also contains a load() method which: "Causes the element to reset and start selecting and loading a new media resource from scratch."

(Ogg isn't the best format to use, as it's only supported by a limited number of browsers. I'd suggest using WebM and MP4 to cover all major browsers - you can use the canPlayType() function to decide on which one to play).

You can then wait for either the loadedmetadata or loadeddata (depending on what you want) events to fire:

video.addEventListener('loadeddata', function() {
   // Video is loaded and can be played
}, false);

You need to use

 $rootScope.$broadcast()

in the controller that must send datas. And in the one that receive those datas, you use

 $scope.$on

Here is a fiddle that i forked a few time ago (I don't know who did it first anymore

http://jsfiddle.net/patxy/RAVFM/

Also you can only set mediaPlayer.reset() and in onDestroy set it to release.

Some of these answers seemed too syntax-heavy, or they produced issues on my Debian Server. This worked perfectly for me:

grep -r --include=\*.txt 'searchterm' ./

...or case-insensitive version...

grep -r -i --include=\*.txt 'searchterm' ./

• grep: command

• -r: recursively

• -i: ignore-case

• --include: all *.txt: text files (escape with \ just in case you have a directory with asterisks in the filenames)

• 'searchterm': What to search

• ./: Start at current directory.

The new keyword creates instances of objects using functions as a constructor. For instance:

var Foo = function() {};
Foo.prototype.bar = 'bar';

var foo = new Foo();
foo instanceof Foo; // true

Instances inherit from the prototype of the constructor function. So given the example above...

foo.bar; // 'bar'

There is no need to create a Java project and let unnecessary Java dependencies and libraries to cling into the project. The question is regarding importing an existing directory into eclipse

Suppose the directory is present in C:/harley/mydir. What you have to do is the following:

• Create a new project (Right click on Project explorer, select New -> Project; from the wizard list, select General -> Project and click next.)

• Give to the project the same name of your target directory (in this case mydir)

• Uncheck Use default location and give the exact location, for example C:/harley/mydir

• Click on Finish

You are done. I do it this way.

objective-c is the primary language used.

i believe there is a mono touch framework that can be used with c#

Adobe also is working in some tools, one is this iPhone Packager which can utilize actionscript code

class Second:
    def __init__(self, data):
        self.data = data

class First:
    def SecondClass(self, data):
        return Second(data)

FirstClass = First()
SecondClass = FirstClass.SecondClass('now you see me')
print SecondClass.data

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill';

If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill'
  AND total = 203;

That's the easiest I could think of (TESTED) and it works!!

char message[50];
fgets(message, 50, stdin);
for( i = 0, j = 0; i < strlen(message); i++){
        message[i-j] = message[i];
        if(message[i] == ' ')
            j++;
}
message[i] = '\0';

Backticks are to be used for table and column identifiers, but are only necessary when the identifier is a MySQL reserved keyword, or when the identifier contains whitespace characters or characters beyond a limited set (see below) It is often recommended to avoid using reserved keywords as column or table identifiers when possible, avoiding the quoting issue.

Single quotes should be used for string values like in the VALUES() list. Double quotes are supported by MySQL for string values as well, but single quotes are more widely accepted by other RDBMS, so it is a good habit to use single quotes instead of double.

MySQL also expects DATE and DATETIME literal values to be single-quoted as strings like '2001-01-01 00:00:00'. Consult the Date and Time Literals documentation for more details, in particular alternatives to using the hyphen - as a segment delimiter in date strings.

So using your example, I would double-quote the PHP string and use single quotes on the values 'val1', 'val2'. NULL is a MySQL keyword, and a special (non)-value, and is therefore unquoted.

None of these table or column identifiers are reserved words or make use of characters requiring quoting, but I've quoted them anyway with backticks (more on this later...).

Functions native to the RDBMS (for example, NOW() in MySQL) should not be quoted, although their arguments are subject to the same string or identifier quoting rules already mentioned.

Backtick (`)

                      ?     ?  ?  ?  ?    ?  ?    ?  ?    ?  ?       ?
$query = "INSERT INTO `table` (`id`, `col1`, `col2`, `date`, `updated`) 
                       VALUES (NULL, 'val1', 'val2', '2001-01-01', NOW())";
                               ????  ?    ?  ?    ?  ?          ?  ?????

Single-quoted (') DATE    --------------------------------------+  ¦¦¦¦¦

Variable interpolation

The quoting patterns for variables do not change, although if you intend to interpolate the variables directly in a string, it must be double-quoted in PHP. Just make sure that you have properly escaped the variables for use in SQL. (It is recommended to use an API supporting prepared statements instead, as protection against SQL injection).

// Same thing with some variable replacements
// Here, a variable table name $table is backtick-quoted, and variables
// in the VALUES list are single-quoted 
$query = "INSERT INTO `$table` (`id`, `col1`, `col2`, `date`) VALUES (NULL, '$val1', '$val2', '$date')";

Prepared statements

When working with prepared statements, consult the documentation to determine whether or not the statement's placeholders must be quoted. The most popular APIs available in PHP, PDO and MySQLi, expect unquoted placeholders, as do most prepared statement APIs in other languages:

// PDO example with named parameters, unquoted
$query = "INSERT INTO `table` (`id`, `col1`, `col2`, `date`) VALUES (:id, :col1, :col2, :date)";

// MySQLi example with ? parameters, unquoted
$query = "INSERT INTO `table` (`id`, `col1`, `col2`, `date`) VALUES (?, ?, ?, ?)";

Characters requring backtick quoting in identifiers:

According to MySQL documentation, you do not need to quote (backtick) identifiers using the following character set:

ASCII: [0-9,a-z,A-Z$_] (basic Latin letters, digits 0-9, dollar, underscore)

You can use characters beyond that set as table or column identifiers, including whitespace for example, but then you must quote (backtick) them.

Also, although numbers are valid characters for identifiers, identifiers cannot consist solely of numbers. If they do they must be wrapped in backticks.

I know this thread is a year old, but the real problem is in your working directory.

I believe that the working directory is C:\Users\Administrator\Documents\Mibot\oops\. Please check for the file named socket.py in this directory. Once you find it, rename or move it. When you import socket, socket.py from the current directory is used instead of the socket.py from Python's directory. Hope this helped. :)

Note: Never use the file names from Python's directory to save your program's file name; it will conflict with your program(s).

I would suggest editing the /etc/default/jenkins

vi /etc/default/jenkins

And changing the $JENKINS_HOME variable (around line 23) to

JENKINS_HOME=/home/jenkins

Then restart the Jenkins with usual

/etc/init.d/jenkins start

You can install M2Eclipse and open the project as maven project in Eclipse. It will create the necessary configuration and entries.

This is also useful for subsequent updates to the pom. With maven eclipse plugin, you will need to manually regenerate the eclipse configuration for each changes.

For PHP >= 5.3.0 use this:

$hostname = gethostname();

For PHP < 5.3.0 but >= 4.2.0 use this:

$hostname = php_uname('n');

For PHP < 4.2.0 use this:

$hostname = getenv('HOSTNAME'); 
if(!$hostname) $hostname = trim(`hostname`); 
if(!$hostname) $hostname = exec('echo $HOSTNAME');
if(!$hostname) $hostname = preg_replace('#^\w+\s+(\w+).*$#', '$1', exec('uname -a')); 

The values() method returns a QuerySet containing dictionaries:

<QuerySet [{'comment_id': 1}, {'comment_id': 2}]>

The values_list() method returns a QuerySet containing tuples:

<QuerySet [(1,), (2,)]>

If you are using values_list() with a single field, you can use flat=True to return a QuerySet of single values instead of 1-tuples:

<QuerySet [1, 2]>

To get a type that implements io.Reader from a []byte slice, you can use bytes.NewReader in the bytes package:

r := bytes.NewReader(byteData)

This will return a value of type bytes.Reader which implements the io.Reader (and io.ReadSeeker) interface.

Don't worry about them not being the same "type". io.Reader is an interface and can be implemented by many different types. To learn a little bit more about interfaces in Go, read Effective Go: Interfaces and Types.

To get first word of string you can do this:

let myStr = "Hello World"
let firstWord = myStr.split(" ")[0]

I'd set up your HTML like so:

<img src="../images/bottle.jpg" alt="bottle" class="thumbnails" id="bottle" />

Then use the following code:

<script>
var images = document.getElementsByTagName("img");
for(var i = 0; i < images.length; i++) {
    var image = images[i];
    image.onclick = function(event) {
         window.location.href = this.id + '.html';
    };
}
</script>

That assigns an onclick event handler to every image on the page (this may not be what you want, you can limit it further if necessary) that changes the current page to the value of the images id attribute plus the .html extension. It's essentially the pure Javascript implementation of @JanPöschko's jQuery answer.

1. Every postal code system uses only A-Z and/or 0-9 and sometimes space/dash

2. Not every country uses postal codes (ex. Ireland outside of Dublin), but we'll ignore that here.

3. The shortest postal code format is Sierra Leone with NN

4. The longest is American Samoa with NNNNN-NNNNNN

5. You should allow one space or dash.

6. Should not begin or end with space or dash

This should cover the above:

(?i)^[a-z0-9][a-z0-9\- ]{0,10}[a-z0-9]$

Of course, you will want to add validation and whatnot, but that is the gist of it.

For me, only "Integer.toHexString(registered)" worked the way I wanted:

char registered = '®';
System.out.println("Answer:"+Integer.toHexString(registered));

This answer will give you only string representations what are usually presented in the tables. Jon Skeet's answer explains more.

Anonymous function:

(function(n) { while(n-- && this.push(0)); return this; }).call([], 5);
// => [0, 0, 0, 0, 0]

A bit shorter with for-loop:

(function(n) { for(;n--;this.push(0)); return this; }).call([], 5);
// => [0, 0, 0, 0, 0]

Works with any Object, just change what's inside this.push().

You can even save the function:

function fill(size, content) {
  for(;size--;this.push(content));
  return this;
}

Call it using:

var helloArray = fill.call([], 5, 'hello');
// => ['hello', 'hello', 'hello', 'hello', 'hello']

Adding elements to an already existing array:

var helloWorldArray = fill.call(helloArray, 5, 'world');
// => ['hello', 'hello', 'hello', 'hello', 'hello', 'world', 'world', 'world', 'world', 'world']

Same idea as Yuushi in using regular expressions, but this uses the findall method within the re library instead of a list comprehension:

import re
regex = re.compile('th.s')
l = ['this', 'is', 'just', 'a', 'test']
matches = re.findall(regex, string)

Flutter now contains a Visibility Widget that you should use to show/hide widgets. The widget can also be used to switch between 2 widgets by changing the replacement.

This widget can achieve any of the states visible, invisible, gone and a lot more.

    Visibility(
      visible: true //Default is true,
      child: Text('Ndini uya uya'),
      //maintainSize: bool. When true this is equivalent to invisible;
      //replacement: Widget. Defaults to Sizedbox.shrink, 0x0
    ),

Jsel is awesome and is based on a real XPath engine. It allows you to create XPath expressions to find any type of JavaScript data, not just objects (strings too).

You can create custom schemas and mappings to give you complete control over how your data is walkable by the XPath engine. A schema is a way of defining how elements, children, attributes, and node values are defined in your data. Then you can create your own expressions to suit.

Given you had a variable called data which contained the JSON from the question, you could use jsel to write:

jsel(data).select("//*[@id=3]")

This will return any node with an id attribute of 3. An attribute is any primitive (string, number, date, regex) value within an object.

If you happen to have both a bash shell and jad:

JAR=(your jar file name)
unzip -d $JAR.tmp $JAR
pushd $JAR.tmp
for f in `find . -name '*.class'`; do
    jad -d $(dirname $f) -s java -lnc $f
done
popd

I might be a tiny, tiny bit off with that, but it should work more or less as advertised. You should end up with $JAR.tmp containing your decompiled files.

I know its been a while since the original post but I like using CTE's and this worked for me:

WITH cte_table_a
AS
(
    SELECT [id] [id]
    , MAX([value]) [value]
    FROM table_a
    GROUP BY [id]
)
UPDATE table_b
SET table_b.code = CASE WHEN cte_table_a.[value] IS NOT NULL THEN cte_table_a.[value] ELSE 124 END
FROM table_b
LEFT OUTER JOIN  cte_table_a
ON table_b.id = cte_table_a.id

$('li').last().addClass('someClass');

if you have multiple

Arrays like this are part of C99, but not part of standard C++. as others have said, a vector is always a much better solution, which is probably why variable sized arrays are not in the C++ standatrd (or in the proposed C++0x standard).

BTW, for questions on "why" the C++ standard is the way it is, the moderated Usenet newsgroup comp.std.c++ is the place to go to.

You can use closures to pass parameters:

iframe.document.addEventListener('click', function(event) {clic(this.id);}, false);

However, I recommend that you use a better approach to access your frame (I can only assume that you are using the DOM0 way of accessing frame windows by their name - something that is only kept around for backwards compatibility):

document.getElementById("myFrame").contentDocument.addEventListener(...);

This has a simple method using SendKeys to unprotect the VBA project. This would get you into the project, so you'd have to continue on using SendKeys to figure out a way to remove the password protection: http://www.pcreview.co.uk/forums/thread-989191.php

And here's one that uses a more advanced, somewhat more reliable method for unprotecting. Again, it will only unlock the VB project for you. http://www.ozgrid.com/forum/showthread.php?t=13006&page=2

I haven't tried either method, but this may save you some time if it's what you need to do...

I had the same problem, with a database field with type "SET" which is an enum type.

I tried to add a value which was not in that list.

The value I tried to add had the decimal value 256, but the enum list only had 8 values.

1: 1   -> A
2: 2   -> B
3: 4   -> C
4: 8   -> D
5: 16  -> E
6: 32  -> F
7: 64  -> G
8: 128 -> H

So I just had to add the additional value to the field.

Reading this documentation entry helped me to understand the problem.

MySQL stores SET values numerically, with the low-order bit of the stored value corresponding to the first set member. If you retrieve a SET value in a numeric context, the value retrieved has bits set corresponding to the set members that make up the column value. For example, you can retrieve numeric values from a SET column like this:

mysql> SELECT set_col+0 FROM tbl_name; If a number is stored into a

If a number is stored into a SET column, the bits that are set in the binary representation of the number determine the set members in the column value. For a column specified as SET('a','b','c','d'), the members have the following decimal and binary values.

SET Member  Decimal Value   Binary Value
    'a'                1          0001
    'b'                2          0010
    'c'                4          0100
