Months are zero-based in Calendar. So 12 is interpreted as december + 1 month. Use

c.set(year, month - 1, day, 0, 0);  

Please try this. This query can be used for date comparison

select * from [User] U where convert(varchar(10),U.DateCreated, 120) = '2014-02-07'

Curl Post + Error Handling + Set Headers [thanks to @mantas-d]:

function curlPost($url, $data=NULL, $headers = NULL) {
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    if(!empty($data)){
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    }

    if (!empty($headers)) {
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    }

    $response = curl_exec($ch);

    if (curl_error($ch)) {
        trigger_error('Curl Error:' . curl_error($ch));
    }

    curl_close($ch);
    return $response;
}


curlPost('google.com', [
    'username' => 'admin',
    'password' => '12345',
]);

Slightly alternative solution to @jpp's but outputting a YearMonth string:

df['YearMonth'] = pd.to_datetime(df['Date']).apply(lambda x: '{year}-{month}'.format(year=x.year, month=x.month))

res = df.groupby('YearMonth')['Values'].sum()

If you know the root password, you can try

su -c "<command1> ; <command2>"  

Probably a silly suggestion compared to others:

if(!preg_match("/^[a-zA-Z0-9]$/",$string)){
    $sortedString=preg_replace("/^[a-zA-Z0-9]+$/","",$string);
}

Execute the following on your terminal to get the latest stable version:

sudo gem install cocoapods

Add --pre to get the latest pre release:

sudo gem install cocoapods --pre

If you originally installed the cocoapods gem using sudo, you should use that command again.

Later on, when you're actively using CocoaPods by installing pods, you will be notified when new versions become available with a CocoaPods X.X.X is now available, please update message.

You can just multiply 1.0

>>> 1.0*144/314

'RESTless' is a term not often used.

You can define 'RESTless' as any system that is not RESTful. For that it is enough to not have one characteristic that is required for a RESTful system.

Most systems are RESTless by this definition because they don't implement HATEOAS.

Safe fix for Mac (Android studio 4.1+) It is in a different directory now, but symlink helps.

Just run in the Terminal this command

ln -s ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins ~/Library/Application\ Support/AndroidStudio4.1

If you have a different Android Studio version or an installation folder adjust the command accordingly.

I got an error that the CURL extension was missing whilst installing WebMail Lite 8 on WAMP (so on Windows).

After reading that libeay32.dll was required which was only present in some of the PHP installation folders (such as 7.1.26), I switched the PHP version in use from 7.2.14 to 7.1.26 in the WAMP PHP version menu, and the error went away.

The plyr package can be used for this. With the ddply() function you can split a data frame on one or more columns and apply a function and return a data frame, then with the summarize() function you can use the columns of the splitted data frame as variables to make the new data frame/;

dat <- read.table(textConnection('Group Score Info
1     1     1    a
2     1     2    b
3     1     3    c
4     2     4    d
5     2     3    e
6     2     1    f'))

library("plyr")

ddply(dat,.(Group),summarize,
    Max = max(Score),
    Info = Info[which.max(Score)])
  Group Max Info
1     1   3    c
2     2   4    d

Try using - declare let $ :any;

or import * as $ from 'jquery/dist/jquery.min.js'; provide exact path of the lib

Bower has finally been deprecated. End of story.

Older answer

From Mattias Petter Johansson, JavaScript developer at Spotify:

In almost all cases, it's more appropriate to use Browserify and npm over Bower. It is simply a better packaging solution for front-end apps than Bower is. At Spotify, we use npm to package entire web modules (html, css, js) and it works very well.

Bower brands itself as the package manager for the web. It would be awesome if this was true - a package manager that made my life better as a front-end developer would be awesome. The problem is that Bower offers no specialized tooling for the purpose. It offers NO tooling that I know of that npm doesn't, and especially none that is specifically useful for front-end developers. There is simply no benefit for a front-end developer to use Bower over npm.

We should stop using bower and consolidate around npm. Thankfully, that is what is happening:

With browserify or webpack, it becomes super-easy to concatenate all your modules into big minified files, which is awesome for performance, especially for mobile devices. Not so with Bower, which will require significantly more labor to get the same effect.

npm also offers you the ability to use multiple versions of modules simultaneously. If you have not done much application development, this might initially strike you as a bad thing, but once you've gone through a few bouts of Dependency hell you will realize that having the ability to have multiple versions of one module is a pretty darn great feature. Note that npm includes a very handy dedupe tool that automatically makes sure that you only use two versions of a module if you actually have to - if two modules both can use the same version of one module, they will. But if they can't, you have a very handy out.

(Note that Webpack and rollup are widely regarded to be better than Browserify as of Aug 2016.)

I experienced the same problem when I copied a text that has an apostrophe from a Word document to my HTML code.

To resolve the issue, all I did was deleted the particular word in my HTML and typed it directly, including the apostrophe. This action nullified the original copy and paste acton and displayed the newly typed apostrophe correctly

I solved it simply by removing the domain from the request url.

Before: https://some.domain.com/_vti_bin/service.svc

After: /_vti_bin/service.svc

try this:

Dim ws as Worksheet

Set ws = Thisworkbook.Sheets("Sheet2")

With ws
    .Range("E2").Formula = "=VLOOKUP(D2,Sheet1!$A:$C,1,0)"
End With

End Sub

This just the simplified version of what you want.
No need to use Application if you will just output the answer in the Range("E2").

If you want to stick with your logic, declare the variables.
See below for example.

Sub Test()

Dim rng As Range
Dim ws1, ws2 As Worksheet
Dim MyStringVar1 As String

Set ws1 = ThisWorkbook.Sheets("Sheet1")
Set ws2 = ThisWorkbook.Sheets("Sheet2")
Set rng = ws2.Range("D2")

With ws2
    On Error Resume Next 'add this because if value is not found, vlookup fails, you get 1004
    MyStringVar1 = Application.WorksheetFunction.VLookup(rng, ws1.Range("A1:C65536").Value, 1, False)
    On Error GoTo 0
    If MyStringVar1 = "" Then MsgBox "Item not found" Else MsgBox MyStringVar1
End With

End Sub

Hope this get's you started.

add "throws IOException" to your method like this:

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

        FileReader reader=new FileReader("db.properties");

        Properties p=new Properties();
        p.load(reader);


    }

Read up on the configuration settings (e.g., display_errors, display_startup_errors, log_errors) and update your php.ini or .htaccess or .user.ini file, whichever is appropriate.

It works.

since async ajax is deprecated try using nested async functions with a Promise. There may be syntax errors.

async function fetch_my_data(_url, _dat) {

   async function promised_fetch(_url, _dat) {

      return new Promise((resolve, reject) => {
         $.ajax({
            url:  _url,
            data: _dat,
            type: 'POST',
            success: (response) => {
               resolve(JSON.parse(response));
            },
            error: (response) => {
               reject(response);
            }
         });
      });
   }

   var _data = await promised_fetch(_url, _dat);
   
   return _data;
}

var _my_data = fetch_my_data('server.php', 'get_my_data=1');

if (layoutManager.findLastCompletelyVisibleItemPosition() == 
 recyclerAdapter.getItemCount() - 1) {
    //load more items.
 }

Fair and simple. This will work.

You should use hash (#) tables, That you actually looking for because variables value will remain till that execution only. e.g. -

declare @TEMP table (ID int, Name varchar(max))
insert into @temp SELECT ID, Name FROM Table

When above two and below two statements execute separately.

SELECT * FROM @TEMP 
WHERE @TEMP.ID  = 1 

The error will show because the value of variable lost when you execute the batch of query second time. It definitely gives o/p when you run an entire block of code.

The hash table is the best possible option for storing and retrieving the temporary value. It last long till the parent session is alive.

It's not clear how you want your Date logic to behave? Usually a good way to deal with default behaviour is the Null Object pattern.

To rotate a DIV we can add some CSS that, well, rotates the DIV using CSS transform rotate.

To toggle the rotation we can keep a flag, a simple variable with a boolean value that tells us what way to rotate.

var rotated = false;

document.getElementById('button').onclick = function() {
    var div = document.getElementById('div'),
        deg = rotated ? 0 : 66;

    div.style.webkitTransform = 'rotate('+deg+'deg)'; 
    div.style.mozTransform    = 'rotate('+deg+'deg)'; 
    div.style.msTransform     = 'rotate('+deg+'deg)'; 
    div.style.oTransform      = 'rotate('+deg+'deg)'; 
    div.style.transform       = 'rotate('+deg+'deg)'; 

    rotated = !rotated;
}

var rotated = false;_x000D_
_x000D_
document.getElementById('button').onclick = function() {_x000D_
    var div = document.getElementById('div'),_x000D_
        deg = rotated ? 0 : 66;_x000D_
_x000D_
    div.style.webkitTransform = 'rotate('+deg+'deg)'; _x000D_
    div.style.mozTransform    = 'rotate('+deg+'deg)'; _x000D_
    div.style.msTransform     = 'rotate('+deg+'deg)'; _x000D_
    div.style.oTransform      = 'rotate('+deg+'deg)'; _x000D_
    div.style.transform       = 'rotate('+deg+'deg)'; _x000D_
    _x000D_
    rotated = !rotated;_x000D_
}

#div {_x000D_
    position:relative; _x000D_
    height: 200px; _x000D_
    width: 200px; _x000D_
    margin: 30px;_x000D_
    background: red;_x000D_
}

<button id="button">rotate</button>_x000D_
<br /><br />_x000D_
<div id="div"></div>

To add some animation to the rotation all we have to do is add CSS transitions

div {
    -webkit-transition: all 0.5s ease-in-out;
    -moz-transition: all 0.5s ease-in-out;
    -o-transition: all 0.5s ease-in-out;
    transition: all 0.5s ease-in-out;
}

var rotated = false;_x000D_
_x000D_
document.getElementById('button').onclick = function() {_x000D_
    var div = document.getElementById('div'),_x000D_
        deg = rotated ? 0 : 66;_x000D_
_x000D_
    div.style.webkitTransform = 'rotate('+deg+'deg)'; _x000D_
    div.style.mozTransform    = 'rotate('+deg+'deg)'; _x000D_
    div.style.msTransform     = 'rotate('+deg+'deg)'; _x000D_
    div.style.oTransform      = 'rotate('+deg+'deg)'; _x000D_
    div.style.transform       = 'rotate('+deg+'deg)'; _x000D_
    _x000D_
    rotated = !rotated;_x000D_
}

#div {_x000D_
    position:relative; _x000D_
    height: 200px; _x000D_
    width: 200px; _x000D_
    margin: 30px;_x000D_
    background: red;_x000D_
    -webkit-transition: all 0.5s ease-in-out;_x000D_
    -moz-transition: all 0.5s ease-in-out;_x000D_
    -o-transition: all 0.5s ease-in-out;_x000D_
    transition: all 0.5s ease-in-out;_x000D_
}

<button id="button">rotate</button>_x000D_
<br /><br />_x000D_
<div id="div"></div>

Another way to do it is using classes, and setting all the styles in a stylesheet, thus keeping them out of the javascript

document.getElementById('button').onclick = function() {
    document.getElementById('div').classList.toggle('rotated');
}

document.getElementById('button').onclick = function() {_x000D_
    document.getElementById('div').classList.toggle('rotated');_x000D_
}

#div {_x000D_
    position:relative; _x000D_
    height: 200px; _x000D_
    width: 200px; _x000D_
    margin: 30px;_x000D_
    background: red;_x000D_
    -webkit-transition: all 0.5s ease-in-out;_x000D_
    -moz-transition: all 0.5s ease-in-out;_x000D_
    -o-transition: all 0.5s ease-in-out;_x000D_
    transition: all 0.5s ease-in-out;_x000D_
}_x000D_
_x000D_
#div.rotated {_x000D_
    -webkit-transform : rotate(66deg); _x000D_
    -moz-transform : rotate(66deg); _x000D_
    -ms-transform : rotate(66deg); _x000D_
    -o-transform : rotate(66deg); _x000D_
    transform : rotate(66deg); _x000D_
}

<button id="button">rotate</button>_x000D_
<br /><br />_x000D_
<div id="div"></div>

I believe this is the simplest example:

header := w.Header()
header.Add("Access-Control-Allow-Origin", "*")
header.Add("Access-Control-Allow-Methods", "DELETE, POST, GET, OPTIONS")
header.Add("Access-Control-Allow-Headers", "Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With")

You can also add a header for Access-Control-Max-Age and of course you can allow any headers and methods that you wish.

Finally you want to respond to the initial request:

if r.Method == "OPTIONS" {
    w.WriteHeader(http.StatusOK)
    return
}

Edit (June 2019): We now use gorilla for this. Their stuff is more actively maintained and they have been doing this for a really long time. Leaving the link to the old one, just in case.

Old Middleware Recommendation below: Of course it would probably be easier to just use middleware for this. I don't think I've used it, but this one seems to come highly recommended.

Did you check the gsl package in your system. Try with this:

ldconfig-p | grep gsl

If gsl is installed, it will display the configuration path. If it is not in the standard path /usr/lib/ then you need to do the following in bash:

export PATH=$PATH:/your/path/to/gsl-config 

If gsl is not installed, simply do

sudo apt-get install libgsl0ldbl
sudo apt-get install gsl-bin libgsl0-dev

I had a problem with the mvabund package and this fixed the error

Cheers!

I have to get the data from a POST method of the PHP code. What worked for me was:

const querystring = require('querystring');
const request = require('request');

const link = 'http://your-website-link.com/sample.php';
let params = { 'A': 'a', 'B': 'b' };

params = querystring.stringify(params); // changing into querystring eg 'A=a&B=b'

request.post({
  headers: { 'Content-Type': 'application/x-www-form-urlencoded' }, // important to interect with PHP
  url: link,
  body: params,
}, function(error, response, body){
  console.log(body);
});

One option is to use a numbers/tally table to drive an iterative process via a pseudo-set based query.

The general idea of char replacement can be demonstrated with a simple character map table approach:

create table charMap (srcChar char(1), replaceChar char(1))
insert charMap values ('a', 'z')
insert charMap values ('b', 'y')


create table testChar(srcChar char(1))
insert testChar values ('1')
insert testChar values ('a')
insert testChar values ('2')
insert testChar values ('b')

select 
coalesce(charMap.replaceChar, testChar.srcChar) as charData
from testChar left join charMap on testChar.srcChar = charMap.srcChar

Then you can bring in the tally table approach to do the lookup on each character position in the string.

create table tally (i int)
declare @i int
set @i = 1
while @i <= 256 begin
    insert tally values (@i)
    set @i = @i + 1
end

create table testData (testString char(10))
insert testData values ('123a456')
insert testData values ('123ab456')
insert testData values ('123b456')

select
    i,
    SUBSTRING(testString, i, 1) as srcChar,
    coalesce(charMap.replaceChar, SUBSTRING(testString, i, 1)) as charData
from testData cross join tally
    left join charMap on SUBSTRING(testString, i, 1) = charMap.srcChar
where i <= LEN(testString)

As I understand, you want the average value for each id at each pass. The solution is

SELECT id, pass, avg(value) FROM data_r1
GROUP BY id, pass;

You can try too to put this into your ~/.vimrc file:

colorscheme Solarized

To sum up the other answers:

• Hibernate: org.hibernate.annotations.Index
• OpenJPA: org.apache.openjpa.persistence.jdbc.Index
• EclipseLink: org.eclipse.persistence.annotations.Index

I would just go for one of them. It will come with JPA 2.1 anyway and should not be too hard to change in the case that you really want to switch your JPA provider.

As an alternative answer, if you Visual Studio SSDT or possibly Red Gate Sql Compare, you could simply run a schema comparison, script it out, drop the old database (possibly make a backup first in case there would be a reason that you will need that data), and then create a new database with the script created by the comparison tool. While on a very small database this may be more work, on a very large database it will be much quicker to simply drop the database then to deal with the different triggers and constraints that may be on the database.

Exchanges will usually publish an up-to-date list of securities on their web pages. For example, these pages offer CSV downloads:

• http://www.nasdaq.com/screening/companies-by-industry.aspx?exchange=NASDAQ&render=download
• http://www.nasdaq.com/screening/companies-by-industry.aspx?exchange=NYSE&render=download
• http://www.asx.com.au/asx/research/ASXListedCompanies.csv

NASDAQ Updated their site, so you will have to modify the URLS:

NASDAQ

• https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=nasdaq&render=download

AMEX

• https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=amex&render=download

NYSE

• https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=nyse&render=download

Depending on your requirement, you could create the map of these URLs by exchange in your own code.

Its totally depends upon your choice, that how you are implementing.
a. Attached process , ex: input on form and print on console
b. Independent process, ex: start a timer, don't close even if console exit.

for a,

Application.Run(new Form1());
//or -------------
Form1 f = new Form1();
f.ShowDialog();

for b, Use thread, or task anything, How to open win form independently?

I've also experienced this problem with none of the classes being generated under the model.tt file. In my case it was down to issues with how I had built the DB in SQL2012. I'd set a column in a table to nullable that was also a foreign key and although I think you should be able to do this it caused a problem in EF5.

As soon as this was cleared and the diagram updated from the database they reappeared.

EF5 VS2013

Well, I think it would be a bad idea to replicate the code which is already present in classes like SimpleDateFormat.

On the other hand, personally I'd suggest avoiding Calendar and Date entirely if you can, and using Joda Time instead, as a far better designed date and time API. For example, you need to be aware that SimpleDateFormat is not thread-safe, so you either need thread-locals, synchronization, or a new instance each time you use it. Joda parsers and formatters are thread-safe.

using System.IO;
using System.Text;
string[] filePaths = Directory.GetFiles(@"path", "*.*", SearchOption.AllDirectories);

If you use two databases you can add another DataClasses.dbml and map the second database into it.
It works.

I like to have my music, movie, and picture files named a certain way. When I download files from the internet, they usually don’t follow my naming convention. I found myself manually renaming each file to fit my style. This got old realy fast, so I decided to write a program to do it for me.

This program can convert the filename to all lowercase, replace strings in the filename with whatever you want, and trim any number of characters from the front or back of the filename.

The program's source code is also available.

In a talk about core containers internals in Python at PyCon 2012, Raymond Hettinger is suggesting to use [None] * n to pre-allocate the length you want.

Slides available as PPT or via Google

The whole slide deck is quite interesting. The presentation is available on YouTube, but it doesn't add much to the slides.

the proper way to do it is to disable constraints with isActive = false. note however that deactivating a constraint removes and releases it, so you have to have strong outlets for them.

Here, if you are converting string into byte[].There is a utility code :

    String[] str = result.replaceAll("\\[", "").replaceAll("\\]","").split(", ");
    byte[] dataCopy = new byte[str.length] ;
    int i=0;
    for(String s:str ) {
        dataCopy[i]=Byte.valueOf(s);
        i++;
    }
    return dataCopy;

This one drove me crazy... basically you need two things:

1) Make sure your DNS is setup to point to your subdomain. This means to make sure you have an A Record in the DNS for your subdomain and point to the same IP.

2) You must add an additional website in IIS 7 named subdomain.example.com

• Sites > Add Website
• Site Name: subdomain.example.com
• Physical Path: select the subdomain directory
• Binding: same ip as example.com
• Host name: subdomain.example.com

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()

You can add in your .bashrc file:

export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")

and it will dynamically change when you update your packages.

For me, the answer was to add two 'Content Roots' in 'File' -> 'Project Structure' -> 'Modules' (in IntelliJ):

1. YourPath\spark-2.2.1-bin-hadoop2.7\python
2. YourPath\spark-2.2.1-bin-hadoop2.7\python\lib\py4j-0.10.4-src.zip

Perhaps you are looking for a context manager?

>>> class Foo(object):
...   def __init__(self):
...     self.bar = None
...   def __enter__(self):
...     if self.bar != 'open':
...       print 'opening the bar'
...       self.bar = 'open'
...   def __exit__(self, type_, value, traceback):
...     if self.bar != 'closed':
...       print 'closing the bar', type_, value, traceback
...       self.bar = 'close'
... 
>>> 
>>> with Foo() as f:
...     # oh no something crashes the program
...     sys.exit(0)
... 
opening the bar
closing the bar <type 'exceptions.SystemExit'> 0 <traceback object at 0xb7720cfc>

means you have already created a class with same name.

For Example:

class ExampleReDeclare {}

// some code here

class ExampleReDeclare {}

That second ExampleReDeclare throw the error.

Try to edit your project build.gradle file and set the android build gradle plugin to classpath 'com.android.tools.build:gradle:3.2.1' within the dependency section.

User the below code for omit/excludes from creating setter and getter. value key should use inside @Getter and @Setter.

@Getter(value = AccessLevel.NONE)

Spring boot 2.3 version, this is working well.

You can use Collections for to sort data:

import java.util.Collections;
import java.util.ArrayList;
import java.util.List;

public class tes
{
    public static void main(String args[])
    {
        List<Integer> lList = new ArrayList<Integer>();

        lList.add(4);       
        lList.add(1);
        lList.add(7);
        lList.add(2);
        lList.add(9);
        lList.add(1);
        lList.add(5);

        Collections.sort(lList);

        for(int i=0; i<lList.size();i++ )
        {
            System.out.println(lList.get(i));
        }

    }
}

To solve the “Keyset does not exist” when browsing from IIS: It may be for the private permission

To view and give the permission:

1. Run>mmc>yes
2. click on file
3. Click on Add/remove snap-in…
4. Double click on certificate
5. Computer Account
6. Next
7. Finish
8. Ok
9. Click on Certificates(Local Computer)
10. Click on Personal
11. Click Certificates

To give the permission:

1. Right Click on the name of certificate
2. All Tasks>Manage Private Keys…
3. Add and give the privilege( adding IIS_IUSRS and giving it the privilege works for me )

You should analyze your style.css file, possibly using Developer Tools in your favorite browser, to see which rule sets font size on the element in a manner that overrides the one in a style attribute. Apparently, it has to be one using the !important specifier, which generally indicates poor logic and structure in styling.

Primarily, modify the style.css file so that it does not use !important. Failing this, add !important to the rule in style attribute. But you should aim at reducing the use of !important, not increasing it.

In an application I was developing I ran into what appeared to be a POST limit of about 2KB. It turned out to be that I was accidentally encoding the parameters into the URL instead of passing them in the body. So if you're running into a problem there, there is definitely a very small limit on the size of POST data you can send encoded into the URL.

If you are using maven build tool then add the below properties to it and doing a maven update will solve the problem

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Use The Constructor.newInstance method. The Class.newInstance method has been deprecated since Java 9 to enhance compiler recognition of instantiation exceptions.

public class Foo<T> {   
    public Foo()
    {
        Class<T> newT = null; 
        instantiateNew(newT);
    }

    T instantiateNew(Class<?> clsT)
    {
        T newT;
        try {
            newT = (T) clsT.getDeclaredConstructor().newInstance();
        } catch (InstantiationException | IllegalAccessException | IllegalArgumentException
            | InvocationTargetException | NoSuchMethodException | SecurityException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            return null;
        }
        return newT;
    }
}

Of course for very simple comparisons you can always use ngMin/ngMax.

Otherwise, you can go with a custom directive, and there is no need of doing any $watch or $observe or $eval or this fancy $setValidity back and forth. Also, there is no need to hook into the postLink function at all. Try to stay out of the DOM as much as possible, as it is against the angular spirit.

Just use the lifecycle hooks the framework gives you. Add a validator and $validate at each change. Simple as that.

app.directive('sameAs', function() {
  return {
    restrict: 'A',
    require: {
      ngModelCtrl: 'ngModel'
    },
    scope: {
      reference: '<sameAs'
    },
    bindToController: true,
    controller: function($scope) {
      var $ctrl = $scope.$ctrl;

      //add the validator to the ngModelController
      $ctrl.$onInit = function() {
        function sameAsReference (modelValue, viewValue) {
          if (!$ctrl.reference || !modelValue) { //nothing to compare
            return true;
          }
          return modelValue === $ctrl.reference;
        }
        $ctrl.ngModelCtrl.$validators.sameas = sameAsReference;
      };

      //do the check at each change
      $ctrl.$onChanges = function(changesObj) {
        $ctrl.ngModelCtrl.$validate();
      };
    },
    controllerAs: '$ctrl'
  };
});

Your plunker.

After spending an entire day fighting with myself on deciding to host my asp.net core application on IIS with InProcess hosting, i am finally proud and relieved to have this solved. Hours of repeatedly going through the same forums, blogs and SO questions which tried their best to solve the problem, i was still stuck after following all the above mentioned approaches. Now here i will describe my experience of solving it.

Step 1: Create a website in IIS

Step 2: Make sure the AppPool for the website has .Net CLR version set to "No Managed Code" and "Enable 32-bit Applications" property in AppPool -> Advanced Settings is set to false

Step 3: Make sure your project is referencing .Net core 2.2

Step 4: Add the following line in your startup.cs file inside ConfigureServices method

services.Configure<IISServerOptions>(options =>
{
     options.AutomaticAuthentication = false;
});

Step 6: Add the following Nuget packages

Microsoft.AspNetCore.App v2.2.5 or greater

Microsoft.AspNetCore.Server.IIS v2.2.2 or greater

Step 7: Add following line to your .csproj file

<AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>

Step 8: Build and publish your code (preferably x64 bitness)

Step 9: Make sure you added your website hostname in etc/hosts file

Step 10: Restart World Wide Web Publishing Service

Now test your asp.net core application and it should be hosted using InProcess hosting In order to verify whether your app is hosted using InProcess mode, check the response headers and it should contain the following line

Server: Microsoft-IIS/10.0 (IIS version could be any depeding on your system)

Update: Download and Install ASP.Net Core Hosting Bundle which is required for it to work

Although this question has already been answered, I think this approach is better : http://jsfiddle.net/kjy112/3CvaD/ extract from this question on StackOverFlow google maps - open marker infowindow given the coordinates:

Each marker gets an "infowindow" entry :

function createMarker(lat, lon, html) {
    var newmarker = new google.maps.Marker({
        position: new google.maps.LatLng(lat, lon),
        map: map,
        title: html
    });

    newmarker['infowindow'] = new google.maps.InfoWindow({
            content: html
        });

    google.maps.event.addListener(newmarker, 'mouseover', function() {
        this['infowindow'].open(map, this);
    });
}

If, for example, x = 5 and is stored as string, you can also just:

x = x + 0

and the new x would be stored as a numeric value.

InitialValue="0" : initial validation will fire when 0th index item is selected in ddl.

<asp:RequiredFieldValidator InitialValue="0" Display="Dynamic" CssClass="error" runat="server" ID="your_id" ValidationGroup="validationgroup" ControlToValidate="your_dropdownlist_id" />

You can also use css rules:

position: fixed ; and top: 0px ;

on your menu tag.

You can use the index of the column you want to apply the multiplication for

df.loc[:,6] *= -1

This will multiply the column with index 6 with -1.

Ive been looking for an nice select dropdown for some time now and I found a good one. So im just gonna leave it here. Its called bootsrap-select

here's the link. check it out. it has editable dropdowns, combo drop downs and more. And its a breeze to add to your project.

If the link dies just search for bootstrap-select by silviomoreto.github.io. This is better because its a normal select tag

1: The arguments to the callback functions are reversed.

.each()'s, $.each()'s, and .map()'s callback function take the index first, and then the element

function (index, element) 

$.map()'s callback has the same arguments, but reversed

function (element, index)

2: .each(), $.each(), and .map() do something special with this

each() calls the function in such a way that this points to the current element. In most cases, you don't even need the two arguments in the callback function.

function shout() { alert(this + '!') }

result = $.each(['lions', 'tigers', 'bears'], shout)

// result == ['lions', 'tigers', 'bears']

For $.map() the this variable refers to the global window object.

3: map() does something special with the callback's return value

map() calls the function on each element, and stores the result in a new array, which it returns. You usually only need to use the first argument in the callback function.

function shout(el) { return el + '!' }

result = $.map(['lions', 'tigers', 'bears'], shout)

// result == ['lions!', 'tigers!', 'bears!']

As per the above answers, I made some changes and I got the correct output.

Step 1: Under "inf.plist" add the Microphone usage permissions ==>

  <key>NSMicrophoneUsageDescription</key>
  <string>${PRODUCT_NAME} Microphone Usage</string>

Step 2:

1. Save record audio file into Local Document Directory

2. Play/Stop recording

3. Get the Duration of Saved audio file

I got this error, while using it on my rocketchat to communicate with my gitlab via enterprise proxy,

Because, was using the https://:8080 but actually, it worked for http://:8080

For those searching for the inverse of this, i.e. looking for tables that do not contain a certain column name, here is the query...

SELECT DISTINCT TABLE_NAME FROM information_schema.columns WHERE 
TABLE_SCHEMA = 'your_db_name' AND TABLE_NAME NOT IN (SELECT DISTINCT 
TABLE_NAME FROM information_schema.columns WHERE column_name = 
'column_name' AND TABLE_SCHEMA = 'your_db_name');

This came in really handy when we began to slowly implement use of InnoDB's special ai_col column and needed to figure out which of our 200 tables had yet to be upgraded.

My understanding of the events is;

Delegate:

A variable to hold reference to method / methods to be executed. This makes it possible to pass around methods like a variable.

Steps for creating and calling the event:

1. The event is an instance of a delegate

2. Since an event is an instance of a delegate, then we have to first define the delegate.

3. Assign the method / methods to be executed when the event is fired (Calling the delegate)

4. Fire the event (Call the delegate)

Example:

using System;

namespace test{
    class MyTestApp{
        //The Event Handler declaration
        public delegate void EventHandler();

        //The Event declaration
        public event EventHandler MyHandler;

        //The method to call
        public void Hello(){
            Console.WriteLine("Hello World of events!");
        }

        public static void Main(){
            MyTestApp TestApp = new MyTestApp();

            //Assign the method to be called when the event is fired
            TestApp.MyHandler = new EventHandler(TestApp.Hello);

            //Firing the event
            if (TestApp.MyHandler != null){
                TestApp.MyHandler();
            }
        }

    }   

}

When you checkout to a commit git checkout <commit-hash> or to a remote branch your HEAD will get detached and try to create a new commit on it.

Commits that are not reachable by any branch or tag will be garbage collected and removed from the repository after 30 days.

Another way to solve this is by creating a new branch for the newly created commit and checkout to it. git checkout -b <branch-name> <commit-hash>

This article illustrates how you can get to detached HEAD state.

The array declaration should be:

Car[] garage = new Car[100];

You can also just assign directly:

garage[1] = new Car("Blue");

There is the instagram public API's tags section that can help you do this.

The DOM methods getElementById(), nextSibling(), childNodes[n], parentNode() and so on return null (defined but having no value) when the call does not return a node object.

The property is defined, but the object it refers to does not exist.

This is one of the few times you may not want to test for equality-

if(x!==undefined) will be true for a null value

but if(x!= undefined) will be true (only) for values that are not either undefined or null.

I've had this problem. See The Python "Connection Reset By Peer" Problem.

You have (most likely) run afoul of small timing issues based on the Python Global Interpreter Lock.

You can (sometimes) correct this with a time.sleep(0.01) placed strategically.

"Where?" you ask. Beats me. The idea is to provide some better thread concurrency in and around the client requests. Try putting it just before you make the request so that the GIL is reset and the Python interpreter can clear out any pending threads.

I'm not exactly sure what it is that you want. Do you want a TimeStamp? Then you can do something simple like:

TimeStamp ts = TimeStamp.FromTicks(value.ToUniversalTime().Ticks);

Since you named a variable epoch, do you want the Unix time equivalent of your date?

DateTime unixStart = DateTime.SpecifyKind(new DateTime(1970, 1, 1), DateTimeKind.Utc);
long epoch = (long)Math.Floor((value.ToUniversalTime() - unixStart).TotalSeconds);

POST means "create new" as in "Here is the input for creating a user, create it for me".

PUT means "insert, replace if already exists" as in "Here is the data for user 5".

You POST to example.com/users since you don't know the URL of the user yet, you want the server to create it.

You PUT to example.com/users/id since you want to replace/create a specific user.

POSTing twice with the same data means create two identical users with different ids. PUTing twice with the same data creates the user the first and updates him to the same state the second time (no changes). Since you end up with the same state after a PUT no matter how many times you perform it, it is said to be "equally potent" every time - idempotent. This is useful for automatically retrying requests. No more 'are you sure you want to resend' when you push the back button on the browser.

A general advice is to use POST when you need the server to be in control of URL generation of your resources. Use PUT otherwise. Prefer PUT over POST.

We can use Angular event bindings to respond to any DOM event. The syntax is simple. We surround the DOM event name in parentheses and assign a quoted template statement to it. -- reference

Since change is on the list of standard DOM events, we can use it:

(change)="saverange()"

In your particular case, since you're using NgModel, you could break up the two-way binding like this instead:

[ngModel]="range" (ngModelChange)="saverange($event)"

Then

saverange(newValue) {
  this.range = newValue;
  this.Platform.ready().then(() => {
     this.rootRef.child("users").child(this.UserID).child('range').set(this.range)
  })
} 

However, with this approach saverange() is called with every keystroke, so you're probably better off using (change).

The %in% operator tells you which elements are among the numers to remove:

> a <- sample (1 : 10)
> remove <- c (2, 3, 5)
> a
 [1] 10  5  2  7  1  6  3  4  8  9
> a %in% remove
 [1] FALSE  TRUE  TRUE FALSE FALSE FALSE  TRUE FALSE FALSE FALSE
> a [! a %in% remove]
 [1] 10  7  1  6  4  8  9

Note that this will silently remove incomparables (stuff like NA or Inf) as well (while it will keep duplicate values in a as long as they are not listed in remove).

• If a can contain incomparables, but remove will not, we can use match, telling it to return 0 for non-matches and incomparables (%in% is a conventient shortcut for match):

  > a <- c (a, NA, Inf)
  > a
   [1]  10   5   2   7   1   6   3   4   8   9  NA Inf
  > match (a, remove, nomatch = 0L, incomparables = 0L)
   [1] 0 3 1 0 0 0 2 0 0 0 0 0
  > a [match (a, remove, nomatch = 0L, incomparables = 0L) == 0L]
  [1]  10   7   1   6   4   8   9  NA Inf
  

  incomparables = 0 is not needed as incomparables will anyways not match, but I'd include it for the sake of readability.
  This is, btw., what setdiff does internally (but without the unique to throw away duplicates in a which are not in remove).

• If remove contains incomparables, you'll have to check for them individually, e.g.

  if (any (is.na (remove))) 
    a <- a [! is.na (a)]
  

  (This does not distinguish NA from NaN but the R manual anyways warns that one should not rely on having a difference between them)

  For Inf/ -Inf you'll have to check both sign and is.finite

I usually just run ez_setup.py. IIRC, that works fine, at least with UAC off.

It also creates an easy_install executable in your Python\scripts subdirectory, which should be in your PATH.

UPDATE: I highly recommend not to bother with easy_install anymore! Jump right to pip, it's better in every regard!
Installation is just as simple: from the installation instructions page, you can download get-pip.py and run it. Works just like the ez_setup.py mentioned above.

Strings are immutable, meaning you can't change a character. Instead, you create new strings.

What you are asking can be done several ways. The most appropriate solution will vary depending on the nature of the changes you are making to the original string. Are you changing only one character? Do you need to insert/delete/append?

Here are a couple ways to create a new string from an existing string, but having a different first character:

str = 'M' + str.Remove(0, 1);

str = 'M' + str.Substring(1);

Above, the new string is assigned to the original variable, str.

I'd like to add that the answers from others demonstrating StringBuilder are also very appropriate. I wouldn't instantiate a StringBuilder to change one character, but if many changes are needed StringBuilder is a better solution than my examples which create a temporary new string in the process. StringBuilder provides a mutable object that allows many changes and/or append operations. Once you are done making changes, an immutable string is created from the StringBuilder with the .ToString() method. You can continue to make changes on the StringBuilder object and create more new strings, as needed, using .ToString().

jQuery's .bind() fires in the order it was bound:

When an event reaches an element, all handlers bound to that event type for the element are fired. If there are multiple handlers registered, they will always execute in the order in which they were bound. After all handlers have executed, the event continues along the normal event propagation path.

Source: http://api.jquery.com/bind/

Because jQuery's other functions (ex. .click()) are shortcuts for .bind('click', handler), I would guess that they are also triggered in the order they are bound.

1. First Remove the adbkey and adbkey.pub from the .android directory in your Home directory.

2. Make .android directory in your home with 710 permissions: $ chmod 710 .android/ and ownership as: chown -R <user>:<user> .android/. Ex:

   $ chmod 710 .android/
   $ chown -R ashan:ashan .android/
   

3. Go to developer options in your mobile and tap option Revoke USB debugging authorizations

4. Turn off all USB Debugging and Developer Options in the device and disconnect the device from your machine.

5. Connect the device again and at first turn on the Developer Options. Then Turn on the USB debugging.

6. At this point in your mobile, you will get a prompt for asking permission from you. Note: you must check the checkbox always accept from this …. option and click ok.

7. Now in you machine, start the adb server: adb start-server.

8. Hopefully when you issue the command: adb devices now, you will see your device ready authorized.

Go to installed updates and just uninstall Internet Explorer 11 Windows update. It works for me.

Mainly for two reasons:

1. Because it doesn't need one (IMHO)
2. Because it's pretty much incompatible with RAII, which is the cornerstone of C++

C++ already offers manual memory management, stack allocation, RAII, containers, automatic pointers, smart pointers... That should be enough. Garbage collectors are for lazy programmers who don't want to spend 5 minutes thinking about who should own which objects or when should resources be freed. That's not how we do things in C++.

Try this,

int dialogButton = JOptionPane.YES_NO_OPTION;
int dialogResult = JOptionPane.showConfirmDialog(this, "Your Message", "Title on Box", dialogButton);
if(dialogResult == 0) {
  System.out.println("Yes option");
} else {
  System.out.println("No Option");
} 

Or you can just run the following command and you will see all databases of the Redis instance without firing up redis-cli:

$ redis-cli INFO | grep ^db
db0:keys=1500,expires=2
db1:keys=200000,expires=1
db2:keys=350003,expires=1

The quick and simple answer is No.

Javascript is quite a high level language and does not have access to this sort of information.

How about

# pattern is by finding a set of numbers in the start and capturing them
as.numeric(gsub("([0-9]+).*$", "\\1", years))

or

# pattern is to just remove _years_old
as.numeric(gsub(" years old", "", years))

or

# split by space, get the element in first index
as.numeric(sapply(strsplit(years, " "), "[[", 1))

Sorry that was a typo. You can either add node_modules to the end of your user's global path variable, or maybe check the permissions associated with that folder (node _modules). The error doesn't seem like the last case, but I've encountered problems similar to yours. I find the first solution enough for most cases. Just go to environment variables and add the path to node_modules to the last part of your user's path variable. Note I'm saying user and not system.

Just add a semicolon to the end of the variable declaration and add the static path to your node_module folder. ( Ex c:\path\to\node_module)

Alternatively you could:

In your CMD

PATH=%PATH%;C:\\path\to\node_module

EDIT

The last solution will work as long as you don't close your CMD. So, use the first solution for a permanent change.

If you want to make it in python you need check this code in your workbench. also write like this. we created a popup box with python.

msgBox = QMessageBox()
msgBox.setText("The document has been modified.")
msgBox.setInformativeText("Do you want to save your changes?")
msgBox.setStandardButtons(QMessageBox.Save | QMessageBox.Discard | QMessageBox.Cancel)
msgBox.setDefaultButton(QMessageBox.Save)
ret = msgBox.exec_()

Problem

I've had the same issue before. After analyzing my code, I realized that attempting to reset the iterator inside of loops slightly increases the time complexity and it also makes the code a bit ugly.

Solution

Open the file and save the rows to a variable in memory.

# initialize list of rows
rows = []

# open the file and temporarily name it as 'my_file'
with open('myfile.csv', 'rb') as my_file:

    # set up the reader using the opened file
    myfilereader = csv.DictReader(my_file)

    # loop through each row of the reader
    for row in myfilereader:
        # add the row to the list of rows
        rows.append(row)

Now you can loop through rows anywhere in your scope without dealing with an iterator.

@alex's post on Kotlin

class Version(inputVersion: String) : Comparable<Version> {

        var version: String
            private set

        override fun compareTo(other: Version) =
            (split() to other.split()).let {(thisParts, thatParts)->
                val length = max(thisParts.size, thatParts.size)
                for (i in 0 until length) {
                    val thisPart = if (i < thisParts.size) thisParts[i].toInt() else 0
                    val thatPart = if (i < thatParts.size) thatParts[i].toInt() else 0
                    if (thisPart < thatPart) return -1

            version = inputVersion
        }
    }

    fun Version.split() = version.split(".").toTypedArray()

usage:

Version("1.2.4").compareTo(Version("0.0.5")) //return 1

I tried the options in the existing answers, mainly the one marked correct which did not work in my scenario. However, what did work was using phpMyAdmin. Select the database and then select the table, from the bottom drop down menu select "Repair table".

• Server type: MySQL
• Server version: 5.7.23 - MySQL Community Server (GPL)
• phpMyAdmin: Version information: 4.7.7

To get the index by value, simply add .index[0] to the end of a query. This will return the index of the first row of the result...

So, applied to your dataframe:

In [1]: a[a['c2'] == 1].index[0]     In [2]: a[a['c1'] > 7].index[0]   
Out[1]: 0                            Out[2]: 4                         

Where the query returns more than one row, the additional index results can be accessed by specifying the desired index, e.g. .index[n]

In [3]: a[a['c2'] >= 7].index[1]     In [4]: a[(a['c2'] > 1) & (a['c1'] < 8)].index[2]  
Out[3]: 4                            Out[4]: 3 

First You need to verify the base, small and thumbnail image are selected in Magento admin.

admin->catalog->manage product->product->image

Then select your image roles(base,small,thumbnail)

Then you call the image using

echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(163, 100);

Hope this helps you.

The Pythonic way to do this:

str(number).rjust(string_width, fill_char)

This way, the original string is returned unchanged if its length is greater than string_width. Example:

a = [1, 10, 100]
for num in a:
    print str(num).rjust(2, '0')

Results:

01
10
100

You can enter array with duplicates and below method will return array with unique elements.

function getUniqueArray(array){
    var uniqueArray = [];
    if (array.length > 0) {
       uniqueArray[0] = array[0];
    }
    for(var i = 0; i < array.length; i++){
        var isExist = false;
        for(var j = 0; j < uniqueArray.length; j++){
            if(array[i] == uniqueArray[j]){
                isExist = true;
                break;
            }
            else{
                isExist = false;
            }
        }
        if(isExist == false){
            uniqueArray[uniqueArray.length] = array[i];
        }
    }
    return uniqueArray;
}

The DatePicker class has methods for getting the month, year, day of month. Or you can use an OnDateChangedListener.

In binary, 0xE9 looks like 1110 1001. If you read about UTF-8 on Wikipedia, you’ll see that such a byte must be followed by two of the form 10xx xxxx. So, for example:

>>> b'\xe9\x80\x80'.decode('utf-8')
u'\u9000'

But that’s just the mechanical cause of the exception. In this case, you have a string that is almost certainly encoded in latin 1. You can see how UTF-8 and latin 1 look different:

>>> u'\xe9'.encode('utf-8')
b'\xc3\xa9'
>>> u'\xe9'.encode('latin-1')
b'\xe9'

(Note, I'm using a mix of Python 2 and 3 representation here. The input is valid in any version of Python, but your Python interpreter is unlikely to actually show both unicode and byte strings in this way.)

I use os.path.exists(), here is a Python 3 script that can be used to check if a directory exists, create one if it does not exist, and delete it if it does exist (if desired).

It prompts users for input of the directory and can be easily modified.

Log4j or slf4j can also be used as logging frameworks in Android together with logcat. See the project android-logging-log4j or log4j support in android

I need to select every production with a category that doesn't contain "Business"

Although I upvoted @Arran's answer as correct, I would also add this... Strictly interpreted, the OP's specification would be implemented as

//production[category[not(contains(., 'Business'))]]

rather than

//production[not(contains(category, 'Business'))]

The latter selects every production whose first category child doesn't contain "Business". The two XPath expressions will behave differently when a production has no category children, or more than one.

It doesn't make any difference in practice as long as every <production> has exactly one <category> child, as in your short example XML. Whether you can always count on that being true or not, depends on various factors, such as whether you have a schema that enforces that constraint. Personally, I would go for the more robust option, since it doesn't "cost" much... assuming your requirement as stated in the question is really correct (as opposed to e.g. 'select every production that doesn't have a category that contains "Business"').

words = [w.replace('[br]', '<br />') for w in words]

These are called List Comprehensions.

I know this post is old, but I had a Situation like this and just want to share my solution. All the answers above work fine. But if you have a Code such as those in data.table chaining Syntax it becomes abit challenging. e.g. I had a Problem like this.

mass <- files[, Veg:=tstrsplit(files$file, "/")[1:4][[1]]][, Rain:=tstrsplit(files$file, "/")[1:4][[2]]][, Roughness:=tstrsplit(files$file, "/")[1:4][[3]]][, Geom:=tstrsplit(files$file, "/")[1:4][[4]]][time_[s]<=12000]

I tried most of the suggestions above and they didn´t work. but I figured out that they can be split after the comma within []. Splitting at ][ doesn´t work.

mass <- files[, Veg:=tstrsplit(files$file, "/")[1:4][[1]]][, 
    Rain:=tstrsplit(files$file, "/")[1:4][[2]]][, 
    Roughness:=tstrsplit(files$file, "/")[1:4][[3]]][, 
    Geom:=tstrsplit(files$file, "/")[1:4][[4]]][`time_[s]`<=12000]

Just for those who want to get $setPristine without having to upgrade to v1.1.x, here is the function I used to simulate the $setPristine function. I was reluctant to use the v1.1.5 because one of the AngularUI components I used is no compatible.

var setPristine = function(form) {
    if (form.$setPristine) {//only supported from v1.1.x
        form.$setPristine();
    } else {
        /*
         *Underscore looping form properties, you can use for loop too like:
         *for(var i in form){ 
         *  var input = form[i]; ...
         */
        _.each(form, function (input) {
            if (input.$dirty) {
                input.$dirty = false;
            }
        });
    }
};

Note that it ONLY makes $dirty fields clean and help changing the 'show error' condition like $scope.myForm.myField.$dirty && $scope.myForm.myField.$invalid.

Other parts of the form object (like the css classes) still need to consider, but this solve my problem: hide error messages.

@user544079

Even though it is very old and irrelevant now, I am replying to help people like me! it should be like this:

<form method="post" action="mailto:$emailID?subject=$MySubject &message= $MyMessageText">

Here $emailID, $MySubject, $MyMessageText are variables which you assign from a FORM or a DATABASE Table or just you can assign values in your code itself. Alternatively you can put the code like this (normally it is not used):

<form method="post" action="mailto:[email protected]?subject=New Registration Alert &message= New Registration requires your approval">

I can never remember all the parameters to Git commands, so I just put an alias in the ~/.gitconfig file that makes more sense to me, so I can remember it, and it results in less typing:

[alias]
url = ls-remote --get-url

After reloading the terminal, you can then just type:

> git url

Here are a few more of my frequently used ones:

[alias]
cd = checkout
ls = branch
lsr = branch --remote
lst = describe --tags

I also highly recommend git-extras which has a git info command which provides much more detailed information on the remote and local branches.

Depending on the purpose of setting the display property, you might want to take a look at

$("#yourElementID").show()

and

$("#yourElementID").hide()

You can add the following to your pom.xml:

<build>
<defaultGoal>install</defaultGoal>
<plugins>
  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
      <source>1.6</source>
      <target>1.6</target>
    </configuration>
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>

    <configuration>
      <archive>
        <manifest>
          <addClasspath>true</addClasspath>
          <mainClass>com.mycompany.package.MainClass</mainClass>
        </manifest>

Afterwards you have to switch via the console to the directory, where the pom.xml is located. Then you have to execute mvn assembly:single and then your executable JAR file with dependencies will be hopefully build. You can check it when switching to the output (target) directory with cd ./target and starting your jar with a command similiar to java -jar mavenproject1-1.0-SNAPSHOT-jar-with-dependencies.jar.

I tested this with Apache Maven 3.0.3.

This query stands good for fetching the values between current date and its next 3 dates

SELECT * FROM tableName
WHERE columName BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 3 DAY)

This will eventually add extra 3 days of buffer to the current date.

In your comment on @Kenneth's answer you're saying that ReadAsStringAsync() is returning empty string.

That's because you (or something - like model binder) already read the content, so position of internal stream in Request.Content is on the end.

What you can do is this:

public static string GetRequestBody()
{
    var bodyStream = new StreamReader(HttpContext.Current.Request.InputStream);
    bodyStream.BaseStream.Seek(0, SeekOrigin.Begin);
    var bodyText = bodyStream.ReadToEnd();
    return bodyText;
}

If you want to get a class name from inside a class method, class.name or self.class.name won't work. These will just output Class, since the class of a class is Class. Instead, you can just use name:

module Foo
  class Bar
    def self.say_name
      puts "I'm a #{name}!"
    end
  end
end

Foo::Bar.say_name

output:

I'm a Foo::Bar!

I see you're having issues with the social share links. I had a similar issue at some point and found this question, but I don't see a complete answer for it. I hope my javascript resolution from below will help:

I had default sharing links that needed to be modified so that the URL that's being shared will have additional UTM parameters concatenated.

My example will be for the Facebook social share link, but it works for all the possible social sharing network links:

The URL that needed to be shared was:

https://mywebsitesite.com/blog/post-name

The default sharing link looked like:

$facebook_default = "https://www.facebook.com/sharer.php?u=https%3A%2F%2mywebsitesite.com%2Fblog%2Fpost-name%2F&t=hello"

I first DECODED it:

console.log( decodeURIComponent($facebook_default) );
=>
https://www.facebook.com/sharer.php?u=https://mywebsitesite.com/blog/post-name/&t=hello

Then I replaced the URL with the encoded new URL (with the UTM parameters concatenated):

console.log( decodeURIComponent($facebook_default).replace( window.location.href, encodeURIComponent(window.location.href+'?utm_medium=social&utm_source=facebook')) );

=>

https://www.facebook.com/sharer.php?u=https%3A%2F%mywebsitesite.com%2Fblog%2Fpost-name%2F%3Futm_medium%3Dsocial%26utm_source%3Dfacebook&t=2018

That's it!

Complete solution:

$facebook_default = $('a.facebook_default_link').attr('href');

$('a.facebook_default_link').attr( 'href', decodeURIComponent($facebook_default).replace( window.location.href, encodeURIComponent(window.location.href+'?utm_medium=social&utm_source=facebook')) );

Clear the cache and cookies and restart the browser .As the style is not suppose to change frequently for a website browser kinda store it .

Since the count is the intended final value, in your query pass

$this->db->distinct();
$this->db->select('accessid');
$this->db->where('record', $record); 
$query = $this->db->get()->result_array();
return count($query);

The count the retuned value

There are multiple ways of doing that you can use either place or grid or even the packmethod.

Sample code:

from tkinter import *
root = Tk()

l = Label(root, text="hello" )
l.pack(padx=6, pady=4) # where padx and pady represent the x and y axis respectively
# well you can also use side=LEFT inside the pack method of the label widget.

To place a widget to on basis of columns and rows , use the grid method:

but = Button(root, text="hello" )
but.grid(row=0, column=1)

You can do the following:

class User(object):
    fullName = "John Doe"

    def __init__(self, name):
        self.SName = name

    def print_names(self):
        print "Names: full name: '%s', name: '%s'" % (self.fullName, self.SName)

user = User('Test Name')

user.fullName # "John Doe"
user.SName # 'Test Name'
user.print_names() # will print you Names: full name: 'John Doe', name: 'Test Name'

E.g any object attributes could be retrieved using istance.

I use outline a css 2 property that simply works. Check this out, is simple and even easy to animate:

.double-border {_x000D_
  display: block;_x000D_
  clear: both;_x000D_
  background: red;_x000D_
  border: 5px solid yellow;_x000D_
  outline: 5px solid blue;_x000D_
  transition: 0.7s all ease-in;_x000D_
  height: 50px;_x000D_
  width: 50px;_x000D_
}_x000D_
.double-border:hover {_x000D_
  background: yellow;_x000D_
  outline-color: red;_x000D_
  border-color: blue;_x000D_
}

<div class="double-border"></div>

In netbeans, you can right click the mouse and then save as a .txt file. Then, based on the created .txt file, you can convert to the file in any format you want to get.

You have a selector ul on line 252 which is setting list-style: square outside none (a square bullet). You'll have to change it to list-style: none or just remove the line.

If you only want to remove the bullets from that specific instance, you can use the specific selector for that list and its items as follows:

ul#groups-list.items-list { list-style: none }

$variable = array('this' => 1,
                    'that' => 1
                    'that' => 1,
                    'this_too' => 1,
                    'that_too' => 1,
                    'this_as_well' => 1,
                    'that_as_well' => 1,
                    'this_one_too' => 1,
                    'that_one_too' => 1,
                    'this_one_as_well' => 1,
                    'that_one_as_well' => 1);

foreach ($variable as $key => $value) {
    User::where($key, '=', $value);
}

If you take clue from Hibernate:

Hibernate reads/writes Object's state with its field. Hibernate also maps the Java Bean style properties to DB Schema. Hibernate Access the fields for loading/saving the object. If the mapping is done by property, hibernate uses the getter and setter.

It is the Encapsulation that differentiates means where you have getter/setters for a field and it is called property, withthat and we hide the underlying data structure of that property within setMethod, we can prevent unwanted change inside setters. All what encapsulation stands for...

Fields must be declared and initialized before they are used. Mostly for class internal use.

Properties can be changed by setter and they are exposed by getters. Here field price has getter/setters so it is property.

class Car{
 private double price;
 public double getPrice() {…};
 private void setPrice(double newPrice) {…};
}

<class name="Car" …>
<property name="price" column="PRICE"/>
</class>

Similarly using fields, [In hibernate it is the recommended way to MAP using fields, where private int id; is annotated @Id, but with Property you have more control]

class Car{
  private double price;
}
<class name="Car">
<property name=" price" column="PRICE" access="field"/>
</class>

Java doc says: Field is a data member of a class. A field is non static, non-transient instance variable. Field is generally a private variable on an instance class.

To get rid of the first column of NAs, you can do it with negative indexing (which removes indices from the R data set). For example:

output = matrix(1:6, 2, 3) # gives you a 2 x 3 matrix filled with the numbers 1 to 6

# output = 
#           [,1] [,2] [,3]
#     [1,]    1    3    5
#     [2,]    2    4    6

output = output[,-1] # this removes column 1 for all rows

# output = 
#           [,1] [,2]
#     [1,]    3    5
#     [2,]    4    6

So you can just add output = output[,-1]after the for loop in your original code.

What ultimately worked for me was the following steps:

1. Configure the Environment Injector Plugin: https://wiki.jenkins-ci.org/display/JENKINS/EnvInject+Plugin
2. Goto to the /job//configure screen
3. In Build Environment section check "Inject environment variables to the build process"
4. In "Properties Content" specified: TZ=America/New_York

Finally I fixed the problem by modifying build.gradle like this:

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 26
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.android.support:design:26.1.0'
}

I've removed these lines as these will produce more errors:

testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

Also I had same problem with migrating an existing project from 2.3 to 3.0.1 and with modifying the project gradle files like this, I came up with a working solution:

build.gradle (module app)

android {
    compileSdkVersion 27
    buildToolsVersion "27.0.1"

    defaultConfig {
        applicationId "com.mobaleghan.tablighcalendar"
        minSdkVersion 16
        targetSdkVersion 27
    }

dependencies {
    implementation 'com.android.support:appcompat-v7:25.1.0'
    implementation 'com.android.support:design:25.1.0'
    implementation 'com.android.support:preference-v7:25.1.0'
    implementation 'com.android.support:recyclerview-v7:25.1.0'
    implementation 'com.android.support:support-annotations:25.1.0'
    implementation 'com.android.support:support-v4:25.1.0'
    implementation 'com.android.support:cardview-v7:25.1.0'
    implementation 'com.google.android.apps.dashclock:dashclock-api:2.0.0'
}

Top level build.gradle

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

In the last version of spring boot 2.1.1.RELEASE, it is simple as :

@RunWith(SpringRunner.class)
@SpringBootTest(classes = SampleApplication.class)
public class CustomerRepositoryIntegrationTest {

    @Autowired
    CustomerRepository repository;

    @Test
    public void myTest() throws Exception {

        Customer customer = new Customer();
        customer.setId(100l);
        customer.setFirstName("John");
        customer.setLastName("Wick");

        repository.save(customer);

        List<?> queryResult = repository.findByLastName("Wick");

        assertFalse(queryResult.isEmpty());
        assertNotNull(queryResult.get(0));
    }
}

Complete code:

Strangely, for me it's SubmitChanges as opposed to SaveChanges:

    foreach (var item in w)
    {
        if (Convert.ToInt32(e.CommandArgument) == item.ID)
        {
            item.Sort = 1;
        }
        else
        {
            item.Sort = null;
        }
        db.SubmitChanges();            
    }                   

Use the value property of the <select> element. For example:

var value = document.getElementById('your_select_id').value;
alert(value);

While @dfa answer of org.apache.commons.lang.StringEscapeUtils.escapeHtml is nice and I have used it in the past it should not be used for escaping HTML (or XML) attributes otherwise the whitespace will be normalized (meaning all adjacent whitespace characters become a single space).

I know this because I have had bugs filed against my library (JATL) for attributes where whitespace was not preserved. Thus I have a drop in (copy n' paste) class (of which I stole some from JDOM) that differentiates the escaping of attributes and element content.

While this may not have mattered as much in the past (proper attribute escaping) it is increasingly become of greater interest given the use use of HTML5's data- attribute usage.

I needed the application URL but with the subdirectory. I used:

root_url(:only_path => false)

This has been more than adequately answered, but you may find this useful: The Function Pointer Tutorials. It is a truly comprehensive treatment of the subject in five chapters!

I found this on the MySQL support page for the Visual Studio connectors.

It appears that they do not support the MySQL to Visual Studio EXPRESS editions.

So to answer your question, yes you may need the ultimate version or professional edition - just not Express to be able to use MySQL with VS.

I would like to point out to you that .val() also works with selects to select the current selected value.

Already answered above, but here's another approach you could take. I can't find the original post I adapted this from, but here's the code for the sake of your question. As noted above, the flatMap() function is what you'd be looking to utilize with Java 8. You can throw it in a utility class and just call "RandomUtils.combine(list1, list2, ...);" and you'd get a single List with all values. Just be careful with the wildcard - you could change this if you want a less generic method. You can also modify it for Sets - you just have to take care when using flatMap() on Sets to avoid data loss from equals/hashCode methods due to the nature of the Set interface.

Edit - If you use a generic method like this for the Set interface, and you happen to use Lombok, make sure you understand how Lombok handles equals/hashCode generation.

  /**
    * Combines multiple lists into a single list containing all elements of
    * every list.
    * 
    * @param <T> - The type of the lists.
    * @param lists - The group of List implementations to combine
    * @return a single List<?> containing all elements of the passed in lists.
    */
   public static <T> List<?> combine(final List<?>... lists) {
      return Stream.of(lists).flatMap(List::stream).collect(Collectors.toList());
   }

In case you are uploading an sql file on cpanel, then try and replace root with your cpanel username in your sql file.

in the case above you could write

CREATE DEFINER = control_panel_username@localhost FUNCTION fnc_calcWalkedDistance

then upload the file. Hope it helps

Yes this is correct, you can't have variables in views (there are other restrictions too).

Views can be used for cases where the result can be replaced with a select statement.

This solution prints the total number of occurrence of a given substring throughout the string, also includes the cases where overlapping matches do exist.

class SubstringMatch{
    public static void main(String []args){
        //String str = "aaaaabaabdcaa";
        //String sub = "aa";
        //String str = "caaab";
        //String sub = "aa";
        String str="abababababaabb";
        String sub = "bab";

        int n = str.length();
        int m = sub.length();

        // index=-1 in case of no match, otherwise >=0(first match position)
        int index=str.indexOf(sub), i=index+1, count=(index>=0)?1:0;
        System.out.println(i+" "+index+" "+count);

        // i will traverse up to only (m-n) position
        while(index!=-1 && i<=(n-m)){   
            index=str.substring(i, n).indexOf(sub);
            count=(index>=0)?count+1:count;
            i=i+index+1;  
            System.out.println(i+" "+index);
        }
        System.out.println("count: "+count);
    }
}

When you create your table, put your td with class = "suma"

$(function(){   

   //funcion suma todo

   var sum = 0;
   $('.suma').each(function(x,y){
       sum += parseInt($(this).text());                                   
   })           
   $('#lblTotal').text(sum);   

   // funcion suma por check                                           

    $( "input:checkbox").change(function(){
    if($(this).is(':checked')){     
        $(this).parent().parent().find('td:last').addClass('suma2');
   }else{       
        $(this).parent().parent().find('td:last').removeClass('suma2');
   }    
   suma2Total();                                                           
   })                                                      

   function suma2Total(){
      var sum2 = 0;
      $('.suma2').each(function(x,y){
        sum2 += parseInt($(this).text());       
      })
      $('#lblTotal2').text(sum2);                                              
   }                                                                      
});

in.next() will return space-delimited strings. Use in.nextLine() if you want to read the whole line. After reading the string, use question = question.replaceAll("\\s","") to remove spaces.

@Asahi pretty much hit the nail on the head, but I just wanted to add a bit of XML for anyone maybe floating in here later via google:

<ListView android:id="@+id/MyListView"
  android:layout_height="match_parent"
  android:layout_width="match_parent"
  android:divider="@android:color/transparent"
  android:dividerHeight="10.0sp"/>

For some reason, values such as "10", "10.0", and "10sp" all are rejected by Android for the dividerHeight value. It wants a floating point number and a unit, such as "10.0sp". As @Goofyahead notes, you can also use display-independent pixels for this value (ie, "10dp").

Check the properties of App.xaml. Is the Build Action still ApplicationDefinition?

You can do this:

CSS:

#container {
    height:175px;
}

#container h3{
    position:absolute;
    bottom:0;
    left:0;
}

Then in HTML:

<div class="row">
    <div class="col-sm-6">
        <img src="//placehold.it/600x300" alt="Logo" />
    </div>
    <div id="container" class="col-sm-6">
        <h3>Some Text</h3>
    </div>
</div>

EDIT: add the <

Here is a good starting point.

HTML:

<div class="containing-table">
    <div class="centre-align">
        <div class="content"></div>
    </div>
</div>

CSS:

.containing-table {
    display: table;
    width: 100%;
    height: 400px; /* for demo only */
    border: 1px dotted blue;
}
.centre-align {
    padding: 10px;
    border: 1px dashed gray;
    display: table-cell;
    text-align: center;
    vertical-align: middle;
}
.content {
    width: 50px;
    height: 50px;
    background-color: red;
    display: inline-block;
    vertical-align: top; /* Removes the extra white space below the baseline */
}

See demo at: http://jsfiddle.net/audetwebdesign/jSVyY/

.containing-table establishes the width and height context for .centre-align (the table-cell).

You can apply text-align and vertical-align to alter .centre-align as needed.

Note that .content needs to use display: inline-block if it is to be centered horizontally using the text-align property.

Running ALTER COLUMN without mentioning attribute NOT NULL will result in the column being changed to nullable, if it is already not. Therefore, you need to first check if the column is nullable and if not, specify attribute NOT NULL. Alternatively, you can use the following statement which checks the nullability of column beforehand and runs the command with the right attribute.

IF COLUMNPROPERTY(OBJECT_ID('Employee', 'U'), 'Salary', 'AllowsNull')=0
    ALTER TABLE [Employee]
        ALTER COLUMN [Salary] NUMERIC(22,5) NOT NULL
ELSE        
    ALTER TABLE [Employee]
        ALTER COLUMN [Salary] NUMERIC(22,5) NULL

This works for me:

pandas.factorize( ['B', 'C', 'D', 'B'] )[0]

Output:

[0, 1, 2, 0]

Maybe just "border-width" instead of "border-weight"? There is no "border-weight" and this property is just ignored and default width is used instead.

From your question, it seems you are running homestead. In that case, make sure you're running the commands in your VM. Many devs including me often make mistake and run artisan commands outside of VM which the commands will try to connect to our local database accessible through localhost which is different from the database used by homestead. Cd to your Homestead directory and run

vagrant ssh

then cd into code if that is where you keep your projects and cd into your project and run php artisan migrate again I hope this will help other people.

Only set the relevant / important CSS properties.

Example (only change the attributes which may cause your div to look completely different):

background: #FFF;
border: none;
color: #000;
display: block;
font: initial;
height: auto;
letter-spacing: normal;
line-height: normal;
margin: 0;
padding: 0;
text-transform: none;
visibility: visible;
width: auto;
word-spacing: normal;
z-index: auto;

Choose a very specific selector, such as div#donttouchme, <div id="donttouchme"></div>. Additionally, you can add `!important before every semicolon in the declaration. Your customers are deliberately trying to mess up your lay-out when this option fails.

@user.route('/<user_id>', defaults={'username': default_value})
@user.route('/<user_id>/<username>')
def show(user_id, username):
   #
   pass

Edit There appears to be a better LZW solution that handles Unicode strings correctly at http://pieroxy.net/blog/pages/lz-string/index.html (Thanks to pieroxy in the comments).

I don't know of any gzip implementations, but the jsolait library (the site seems to have gone away) has functions for LZW compression/decompression. The code is covered under the LGPL.

// LZW-compress a string
function lzw_encode(s) {
    var dict = {};
    var data = (s + "").split("");
    var out = [];
    var currChar;
    var phrase = data[0];
    var code = 256;
    for (var i=1; i<data.length; i++) {
        currChar=data[i];
        if (dict[phrase + currChar] != null) {
            phrase += currChar;
        }
        else {
            out.push(phrase.length > 1 ? dict[phrase] : phrase.charCodeAt(0));
            dict[phrase + currChar] = code;
            code++;
            phrase=currChar;
        }
    }
    out.push(phrase.length > 1 ? dict[phrase] : phrase.charCodeAt(0));
    for (var i=0; i<out.length; i++) {
        out[i] = String.fromCharCode(out[i]);
    }
    return out.join("");
}

// Decompress an LZW-encoded string
function lzw_decode(s) {
    var dict = {};
    var data = (s + "").split("");
    var currChar = data[0];
    var oldPhrase = currChar;
    var out = [currChar];
    var code = 256;
    var phrase;
    for (var i=1; i<data.length; i++) {
        var currCode = data[i].charCodeAt(0);
        if (currCode < 256) {
            phrase = data[i];
        }
        else {
           phrase = dict[currCode] ? dict[currCode] : (oldPhrase + currChar);
        }
        out.push(phrase);
        currChar = phrase.charAt(0);
        dict[code] = oldPhrase + currChar;
        code++;
        oldPhrase = phrase;
    }
    return out.join("");
}

You can't do it with client side script only... you could make an AJAX call to some server side code that will send an email...

If you want to open another application and it is not installed you can send it to the Google App Store to download

1. First create the openOtherApp method for example

   public static boolean openOtherApp(Context context, String packageName) {
       PackageManager manager = context.getPackageManager();
        try {
           Intent intent = manager.getLaunchIntentForPackage(packageName);
           if (intent == null) {
               //the app is not installed
               try {
                   intent = new Intent(Intent.ACTION_VIEW);
                   intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                   intent.setData(Uri.parse("market://details?id=" + packageName));
                   context.startActivity(intent);
               } catch (ActivityNotFoundException e) {
                   //throw new ActivityNotFoundException();
                   return false;
               }
   
            }
            intent.addCategory(Intent.CATEGORY_LAUNCHER);
            context.startActivity(intent);
            return true;
       } catch (ActivityNotFoundException e) {
           return false;
       }
   
   }
   

2.- Usage

openOtherApp(getApplicationContext(), "com.packageappname");

You might check Select2 plugin:

http://ivaynberg.github.io/select2/

Select2 is a jQuery based replacement for select boxes. It supports searching, remote data sets, and infinite scrolling of results.

It's quite popular and very maintainable. It should cover most of your needs if not all.

You can use the following query to create a table to a particular database in MySql.

create database if not exists `test`;

USE `test`;

SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;

/*Table structure for table `test` */

CREATE TABLE IF NOT EXISTS `tblsample` (

  `id` int(11) NOT NULL auto_increment,   
  `recid` int(11) NOT NULL default '0',       
  `cvfilename` varchar(250)  NOT NULL default '',     
  `cvpagenumber`  int(11) NULL,     
  `cilineno` int(11)  NULL,    
  `batchname`  varchar(100) NOT NULL default '',
  `type` varchar(20) NOT NULL default '',    
  `data` varchar(100) NOT NULL default '',
   PRIMARY KEY  (`id`)

);

This is my "one-line" solution:

$.postJSON = function(url, data, func) { $.post(url+(url.indexOf("?") == -1 ? "?" : "&")+"callback=?", data, func, "json"); }

In order to use jsonp, and POST method, this function adds the "callback" GET parameter to the URL. This is the way to use it:

$.postJSON("http://example.com/json.php",{ id : 287 }, function (data) {
   console.log(data.name);
});

The server must be prepared to handle the callback GET parameter and return the json string as:

jsonp000000 ({"name":"John", "age": 25});

in which "jsonp000000" is the callback GET value.

In PHP the implementation would be like:

print_r($_GET['callback']."(".json_encode($myarr).");");

I made some cross-domain tests and it seems to work. Still need more testing though.

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

The answers to this question are a little out of date and missing potentially key steps, so this is an updated guide for installing an app from an external developer.

----- How to Resign an iOS App -----

Let's say you receive an app (e.g. MyApp.ipa) from another developer, and you want to be able to install and run it on your devices (by using ideviceinstaller, for example).

Prepare New Signing Assets

The first step is to attain a Provisioning Profile which includes all of the devices you wish to install and run on. Ensure that the profile contains a certificate that you have installed in your Keychain Access (e.g. iPhone Developer: Some Body (XXXXXXXXXX) ). Download the profile (MyProfile.mobileprovision) so you can replace the profile embedded in the app.

Next, we are going to prepare an entitlements file to include in the signing. Open up your terminal and run the following.

$ security cms -D -i path/to/MyProfile.mobileprovision > provision.plist

This will create an xml file describing your Provisioning Profile. Next, we want to extract the entitlements into a file.

$ /usr/libexec/PlistBuddy -x -c 'Print :Entitlements' provision.plist > entitlements.plist

Replace The Provisioning Profile and Resign App

If you are working with a .ipa file, first, unzip the app (if you have a .app instead, you can skip this step).

$ unzip MyApp.ipa

Your working directory will now contain Payload/ and Payload/MyApp.app/. Next, remove the old code signature files.

$ rm -rf Payload/MyApp.app/_CodeSignature

Replace the existing provisioning profile (i.e. embedded.mobileprovision) with your own.

$ cp path/to/MyProfile.mobileprovision Payload/MyApp.app/embedded.mobileprovision

Now sign the app with the certificate included in your provisioning profile and the entitlements.plist that you created earlier.

$ /usr/bin/codesign -f -s "iPhone Developer: Some Body (XXXXXXXXXX)" --entitlements entitlements.plist Payload/MyApp.app

IMPORTANT: You must also resign all frameworks included in the app. You will find these in Payload/MyApp.app/Frameworks. If the app is written in Swift or if it includes any additional frameworks these must be resigned or the app will install but not run.

$ /usr/bin/codesign -f -s "iPhone Developer: Some Body (XXXXXXXXXX)" --entitlements entitlements.plist Payload/MyApp.app/Frameworks/*

You can now rezip the app.

$ zip -qr MyApp-resigned.ipa Payload

Done

You may now remove the Payload directory since you have your original app (MyApp.ipa) and your resigned version (MyApp-resigned.ipa). You can now install MyApp-resigned.ipa on any device included in your provisioning profile.

Use a iterator to loop through list and then delete the required object.

    Iterator itr = a.iterator();
    while(itr.hasNext()){
        if(itr.next().equals("acbd"))
            itr.remove();
    }

I frequently use std::string to hold utf-8 characters without any problems at all. I heartily recommend doing this when interfacing with API's which use utf-8 as the native string type as well.

For example, I use utf-8 when interfacing my code with the Tcl interpreter.

The major caveat is the length of the std::string, is no longer the number of characters in the string.

It depends a bit on your version. Before 5.0.13 this is not possible with mysqldump.

From the mysqldump man page (v 5.1.30)

 --routines, -R

      Dump stored routines (functions and procedures) from the dumped
      databases. Use of this option requires the SELECT privilege for the
      mysql.proc table. The output generated by using --routines contains
      CREATE PROCEDURE and CREATE FUNCTION statements to re-create the
      routines. However, these statements do not include attributes such
      as the routine creation and modification timestamps. This means that
      when the routines are reloaded, they will be created with the
      timestamps equal to the reload time.
      ...

      This option was added in MySQL 5.0.13. Before that, stored routines
      are not dumped. Routine DEFINER values are not dumped until MySQL
      5.0.20. This means that before 5.0.20, when routines are reloaded,
      they will be created with the definer set to the reloading user. If
      you require routines to be re-created with their original definer,
      dump and load the contents of the mysql.proc table directly as
      described earlier.

It is stored in a file called connections.xml under

\Users\[User]\AppData\Roaming\SQL Developer\System\

When I renamed the file, all my connection info went away. I renamed it back, and it all came back. When I viewed the XML file, I found both test connection aliases, ports, usernames, roles, authentication types, etc.

This while else statement should only execute the else code when the condition is false, this means it will always execute it. But, there is a catch, when you use the break keyword within the while loop, the else statement should not execute.

The code that satisfies does condition is only:

boolean entered = false;
while (condition) {
   entered = true; // Set it to true stright away
   // While loop code


   // If you want to break out of this loop
   if (condition) {
      entered = false;
      break;
   }
} if (!entered) {
   // else code
}

You could use:

filter: brightness(50%);
-webkit-filter: brightness(50%);
-moz-filter: brightness(50%);
-o-filter: brightness(50%);
-ms-filter: brightness(50%);

Python lists have no built-in pre-allocation. If you really need to make a list, and need to avoid the overhead of appending (and you should verify that you do), you can do this:

l = [None] * 1000 # Make a list of 1000 None's
for i in xrange(1000):
    # baz
    l[i] = bar
    # qux

Perhaps you could avoid the list by using a generator instead:

def my_things():
    while foo:
        #baz
        yield bar
        #qux

for thing in my_things():
    # do something with thing

This way, the list isn't every stored all in memory at all, merely generated as needed.

This worked for me:

Check the current role you are logged into by using: SELECT CURRENT_USER, SESSION_USER;

Note: It must match with Owner of the schema.

Schema | Name | Type | Owner
--------+--------+-------+----------

If the owner is different, then give all the grants to the current user role from the admin role by :

GRANT 'ROLE_OWNER' to 'CURRENT ROLENAME';

Then try to execute the query, it will give the output as it has access to all the relations now.

I've used Aspose.Words to do mail merge in .NET. I believe that they also have a Java version.

Select the div which has role dialog then get the appropriate buttons in it and set the CSS.

$("div[role=dialog] button:contains('Save')").css("color", "green");
$("div[role=dialog] button:contains('Cancel')").css("color", "red"); 

I think I have figured it out, is it right?:

mysql_query("START TRANSACTION");

$a1 = mysql_query("INSERT INTO rarara (l_id) VALUES('1')");
$a2 = mysql_query("INSERT INTO rarara (l_id) VALUES('2')");

if ($a1 and $a2) {
    mysql_query("COMMIT");
} else {        
    mysql_query("ROLLBACK");
}

Unless I have misunderstood:

$("e").prepend("<yourelem>Text</yourelem>");

Or

$("<yourelem>Text</yourelem>").prependTo("e");

Although it sounds like from your description that there is some condition attached, so

if (SomeCondition){
    $("e").prepend("<yourelem>Text</yourelem>");
}
else{
    $("e").append("<yourelem>Text</yourelem>");
}

I encountered a similar error message. I was able to fix it without enabling remote errors.

In Report Builder 3.0, when I used the Run button to run the report, an error alert appeared, saying

An error has occurred during report processing. (rsProcessingAborted)
[OK] [Details...]

Pressing the details button gave me a text box where I saw this text:

For more information about this error navigate to the report server
on the local server machine, or enable remote errors
----------------------------
Query execution failed for dataset 'DataSet1'. (rsErrorExecutingCommand)

I was confused and frustrated, because my report did not have a dataset named 'DataSet1'. I even opened the .rdl file in a text editor to be sure. After a while, I noticed that there was more text in the text box below what I could read. The full error message was:

For more information about this error navigate to the report server
on the local server machine, or enable remote errors
----------------------------
Query execution failed for dataset 'DataSet1'. (rsErrorExecutingCommand)

----------------------------
The execution failed for the shared data set 'CustomerDetailsDataSet'.  
(rsDataSetExecutionError)
----------------------------
An error has occurred during report processing. (rsProcessingAborted)

I did have a shared dataset named 'CustomerDetailsDataSet'. I opened the query (which was a full SQL query entered in text mode) in SQL Server Management Studio, and ran it there. I got error messages which clearly pointed to a certain table, where a column I had been using had been renamed and changed.

From that point, it was straightforward to modify my query so that it worked with the new column, then paste that modification into the shared dataset 'CustomerDetailsDataSet', and then nudge the report in Report Builder to recognise the change to the shared dataset.

After this fix, my reports no longer triggered this error.

You can use @JsonIgnoreProperties at class level and put variables you want to igonre in json in "value" parameter.Worked for me fine.

@JsonIgnoreProperties(value = { "myVariable1","myVariable2" })
public class MyClass {
      private int myVariable1;,
      private int myVariable2;
}

<asp:RequiredFieldValidator InitialValue="-1" ID="Req_ID" Display="Dynamic" 
    ValidationGroup="g1" runat="server" ControlToValidate="ControlID"
    Text="*" ErrorMessage="ErrorMessage"></asp:RequiredFieldValidator>

Way 1: only works for dataURL, not for other types of url.

function dataURLtoFile(dataurl, filename) {
    var arr = dataurl.split(','), mime = arr[0].match(/:(.*?);/)[1],
        bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n);
    while(n--){
        u8arr[n] = bstr.charCodeAt(n);
    }
    return new File([u8arr], filename, {type:mime});
}

//Usage example:
var file = dataURLtoFile('data:image/png;base64,......', 'a.png');
console.log(file);

Way 2: works for any type of url, (http url, dataURL, blobURL, etc...)

//return a promise that resolves with a File instance
function urltoFile(url, filename, mimeType){
    mimeType = mimeType || (url.match(/^data:([^;]+);/)||'')[1];
    return (fetch(url)
        .then(function(res){return res.arrayBuffer();})
        .then(function(buf){return new File([buf], filename, {type:mimeType});})
    );
}

//Usage example:
urltoFile('data:image/png;base64,......', 'a.png')
.then(function(file){
    console.log(file);
})

Both works in Chrome and Firefox.

Run this command in your project folder. Use serve instead of build

node --max_old_space_size=8000 node_modules/@angular/cli/bin/ng serve  --prod --port=4202

Usually I prefer to use this extension:

Swift 3.x and Swift 4.0:

extension FileManager {
    class func documentsDir() -> String {
        var paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true) as [String]
        return paths[0]
    }
    
    class func cachesDir() -> String {
        var paths = NSSearchPathForDirectoriesInDomains(.cachesDirectory, .userDomainMask, true) as [String]
        return paths[0]
    }
}

Swift 2.x:

extension NSFileManager {
    class func documentsDir() -> String {
        var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true) as [String]
        return paths[0]
    }
    
    class func cachesDir() -> String {
        var paths = NSSearchPathForDirectoriesInDomains(.CachesDirectory, .UserDomainMask, true) as [String]
        return paths[0]
    }
}

<table border="1"></table>

should do the trick.

1. Open $REDIS_HOME/redis.conf and uncomment requirepass -YOUR-PASSWORD-HERE- and write down your password in the specified lines.

2. Login to redis using redis-cli and verify your password in the database using auth -YOUR-PASSWORD-HERE- command.

3. Disable protected mode by changing its string in $REDIS_HOME/redis.conf to protected-mode no.

4. Search for all bind ports values and comment all of them. Just add bind 0.0.0.0 to $REDIS_HOME/redis.conf file.

5. Disable your firewall or open redis port.

6. Start redis using ./redis-server $REDIS_HOME/redis.conf.

7. Check the configuration via ./redis-cli -h -YOUR-IP- -a -YOUR-PASSWORD-HERE-.

8. Check the configuration via ./redis-cli -h -YOUR-IP- ping.

You were just adding the html string. Not the element you created with a click event listener.

Try This:

<html>
<head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script>
</head>
<body>
    <table id="addNodeTable">
        <tr>
            <td>
                Row 1
            </td>
        </tr>
        <tr >
            <td>
                Row 2
            </td>
        </tr>
    </table>
</body>
</html>
<script type="text/javascript">
    $(document).ready(function() {
        var test = $('<button>Test</button>').click(function () {
            alert('hi');
        });
        $("#addNodeTable tr:last").append('<tr><td></td></tr>').find("td:last").append(test);

    });
</script>

Your live apps will not be taken down. Nothing will happen to anything that is live in the app store.

Once they formally expire, the only thing that will be impacted is your ability to sign code (and thus make new builds and provide updates).

Regarding your distribution certificate, once it expires, it simply disappears from the ‘Certificates, Identifier & Profiles’ section of Member Center. If you want to renew it before it expires, revoke the current certificate and you will get a button to request a new one.

Regarding the provisioning profile, don't worry about it before expiration, just keep using it. It's easy enough to just renew it once it expires.

The peace of mind is that nothing will happen to your live app in the store.

There is a version conflict between jar/dependency please check all version of spring is same. if you use maven remove version of dependency and use Spring.io dependency.it handle version conflict. Add this in your pom

 <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>2.0.1.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
  </dependency>

Based on what @user225312 said, you can use .zfill() to add paddng to numbers converted to strings.

My approach is to leave number as a number until the moment you want to convert it into string:

>>> num = 11
>>> padding = 3
>>> print(str(num).zfill(padding))
011

As stated in PostgreSQL docs here:

The SQL CASE expression is a generic conditional expression, similar to if/else statements in other programming languages.

Code snippet specifically answering your question:

SELECT field1, field2,
  CASE
    WHEN field1>0 THEN field2/field1
    ELSE 0
  END 
  AS field3
FROM test

There is contextlib.redirect_stdout() function in Python 3.4:

import io
from contextlib import redirect_stdout

with io.StringIO() as buf, redirect_stdout(buf):
    print('redirected')
    output = buf.getvalue()

Here's code example that shows how to implement it on older Python versions.

Your problem is basically that you never specified the right path to the file.

Try instead, from your main script:

from folder.file import Klasa

Or, with from folder import file:

from folder import file
k = file.Klasa()

Or again:

import folder.file as myModule
k = myModule.Klasa()

For the record an alternative approach might be to make the clickable layer the overlay: you make it semi-transparent and then place the "overlay" image behind it (somewhat counterintuitively, the "overlay" image could then be opaque). Depending on what you're trying to do, you might well be able to get the exact same visual effect (of an image and a clickable layer semi-transparently superimposed on top of each other), while avoiding clickability problems (because the "overlay" is in fact in the background).

Very short ES6 functions using template literals. Be aware that you need to encode/decode the values by yourself but it'll work out of the box for simplier purposes like storing version numbers.

const getCookie = (cookieName) => {
  return (document.cookie.match(`(^|;) *${cookieName}=([^;]*)`)||[])[2]
}
  
const setCookie = (cookieName, value, days=360, path='/') => {
  let expires = (new Date(Date.now()+ days*86400*1000)).toUTCString();
  document.cookie = `${cookieName}=${value};expires=${expires};path=${path};`
}

const deleteCookie = (cookieName) => {
  document.cookie = `${cookieName}=;expires=Thu, 01 Jan 1970 00:00:01 GMT;path=/;`;
}  

Spring 2 introduced ResponseStatusException using this you can return String, different HTTP status code, DTO at the same time.

@PostMapping("/save")
public ResponseEntity<UserDto> saveUser(@RequestBody UserDto userDto) {
    if(userDto.getId() != null) {
        throw new ResponseStatusException(HttpStatus.NOT_ACCEPTABLE,"A new user cannot already have an ID");
    }
    return ResponseEntity.ok(userService.saveUser(userDto));
}

As David and Remou pointed out, vbCrLf if you want a carriage-return-linefeed combination. Otherwise, Chr(13) and Chr(10) (although some VB-derivatives have vbCr and vbLf; VBScript may well have those, worth checking before using Chr).

There are two parts to the model, the model definition, saved by Supervisor as graph.pbtxt in the model directory and the numerical values of tensors, saved into checkpoint files like model.ckpt-1003418.

The model definition can be restored using tf.import_graph_def, and the weights are restored using Saver.

However, Saver uses special collection holding list of variables that's attached to the model Graph, and this collection is not initialized using import_graph_def, so you can't use the two together at the moment (it's on our roadmap to fix). For now, you have to use approach of Ryan Sepassi -- manually construct a graph with identical node names, and use Saver to load the weights into it.

(Alternatively you could hack it by using by using import_graph_def, creating variables manually, and using tf.add_to_collection(tf.GraphKeys.VARIABLES, variable) for each variable, then using Saver)

Do not use this return `${ pre }_${ new Date().getTime()}`;. It's better to have the array index instead of that because, even though it's not ideal, that way you will at least get some consistency among the list components, with the new Date function you will get constant inconsistency. That means every new iteration of the function will lead to a new truly unique key.

The unique key doesn't mean that it needs to be globally unique, it means that it needs to be unique in the context of the component, so it doesn't run useless re-renders all the time. You won't feel the problem associated with new Date initially, but you will feel it, for example, if you need to get back to the already rendered list and React starts getting all confused because it doesn't know which component changed and which didn't, resulting in memory leaks, because, you guessed it, according to your Date key, every component changed.

Now to my answer. Let's say you are rendering a list of YouTube videos. Use the video id (arqTu9Ay4Ig) as a unique ID. That way, if that ID doesn't change, the component will stay the same, but if it does, React will recognize that it's a new Video and change it accordingly.

It doesn't have to be that strict, the little more relaxed variant is to use the title, like Erez Hochman already pointed out, or a combination of the attributes of the component (title plus category), so you can tell React to check if they have changed or not.

edited some unimportant stuff

It's not a direct answer to the question, however I would suggest in most cases to simply set multiple classes to each element:

<div class="myclass one"></div>
<div class="myclass two></div>
<div class="myclass three"></div>

In this way you can set rules for all myclass elements and then more specific rules for one, two and three.

.myclass { color: #f00; }

.two { font-weight: bold; }

etc.

I discovered an error in my first post, so I decided to sit down and do the the math. What I found is that the number system used to identify Excel columns is not a base 26 system, as another person posted. Consider the following in base 10. You can also do this with the letters of the alphabet.

Space:.........................S1, S2, S3 : S1, S2, S3
....................................0, 00, 000 :.. A, AA, AAA
....................................1, 01, 001 :.. B, AB, AAB
.................................... …, …, … :.. …, …, …
....................................9, 99, 999 :.. Z, ZZ, ZZZ
Total states in space: 10, 100, 1000 : 26, 676, 17576
Total States:...............1110................18278

Excel numbers columns in the individual alphabetical spaces using base 26. You can see that in general, the state space progression is a, a^2, a^3, … for some base a, and the total number of states is a + a^2 + a^3 + … .

Suppose you want to find the total number of states A in the first N spaces. The formula for doing so is A = (a)(a^N - 1 )/(a-1). This is important because we need to find the space N that corresponds to our index K. If I want to find out where K lies in the number system I need to replace A with K and solve for N. The solution is N = log{base a} (A (a-1)/a +1). If I use the example of a = 10 and K = 192, I know that N = 2.23804… . This tells me that K lies at the beginning of the third space since it is a little greater than two.

The next step is to find exactly how far in the current space we are. To find this, subtract from K the A generated using the floor of N. In this example, the floor of N is two. So, A = (10)(10^2 – 1)/(10-1) = 110, as is expected when you combine the states of the first two spaces. This needs to be subtracted from K because these first 110 states would have already been accounted for in the first two spaces. This leaves us with 82 states. So, in this number system, the representation of 192 in base 10 is 082.

The C# code using a base index of zero is

    private string ExcelColumnIndexToName(int Index)
    {
        string range = string.Empty;
        if (Index < 0 ) return range;
        int a = 26;
        int x = (int)Math.Floor(Math.Log((Index) * (a - 1) / a + 1, a));
        Index -= (int)(Math.Pow(a, x) - 1) * a / (a - 1);
        for (int i = x+1; Index + i > 0; i--)
        {
            range = ((char)(65 + Index % a)).ToString() + range;
            Index /= a;
        }
        return range;
    }

//Old Post

A zero-based solution in C#.

    private string ExcelColumnIndexToName(int Index)
    {
        string range = "";
        if (Index < 0 ) return range;
        for(int i=1;Index + i > 0;i=0)
        {
            range = ((char)(65 + Index % 26)).ToString() + range;
            Index /= 26;
        }
        if (range.Length > 1) range = ((char)((int)range[0] - 1)).ToString() + range.Substring(1);
        return range;
    }

Initital add & commit worked like a charm. I guess it's just a matter of understanding Git's methodology of managing a project within the repository.

After that I've managed to push my data straight-away with no hassle.

bmail. Just install the EXE and run a line like this:

bmail -s myMailServer -f [email protected] -t [email protected] -a "Production Release Performed"

string MyConString = "Data Source='mysql7.000webhost.com';" +
"Port=3306;" +
"Database='a455555_test';" +
"UID='a455555_me';" +
"PWD='something';";

I'm a bit surprised nobody has talked about the new SubtleCrypto API yet.

To get an hash from a string, you can use the subtle.digest method :

function getHash(str, algo = "SHA-256") {_x000D_
  let strBuf = new TextEncoder('utf-8').encode(str);_x000D_
  return crypto.subtle.digest(algo, strBuf)_x000D_
    .then(hash => {_x000D_
      window.hash = hash;_x000D_
      // here hash is an arrayBuffer, _x000D_
      // so we'll connvert it to its hex version_x000D_
      let result = '';_x000D_
      const view = new DataView(hash);_x000D_
      for (let i = 0; i < hash.byteLength; i += 4) {_x000D_
        result += ('00000000' + view.getUint32(i).toString(16)).slice(-8);_x000D_
      }_x000D_
      return result;_x000D_
    });_x000D_
}_x000D_
_x000D_
getHash('hello world')_x000D_
  .then(hash => {_x000D_
    console.log(hash);_x000D_
  });
