Follow these steps

1. Add cors dependency. type the following in cli inside your project directory

npm install --save cors

2. Include the module inside your project

var cors = require('cors');

3. Finally use it as a middleware.

app.use(cors());

Take a look at this post, it seems like for later versions of Python, certificates are not pre installed which seems to cause this error. You should be able to run the following command to install the certifi package: /Applications/Python\ 3.6/Install\ Certificates.command

Post 1: urllib and "SSL: CERTIFICATE_VERIFY_FAILED" Error

Post 2: Airbrake error: urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate

$ pip install pickle5

import pickle5 as pickle

pb = pickle.PickleBuffer(b"foo")
data = pickle.dumps(pb, protocol=5)
assert pickle.loads(data) == b"foo"

This package backports all features and APIs added in the pickle module in Python 3.8.3, including the PEP 574 additions. It should work with Python 3.5, 3.6 and 3.7.

Basic usage is similar to the pickle module, except that the module to be imported is pickle5:

https://pypi.org/project/pickle5/

Turns out, when the table name is different than the model name, you have to change the annotations to:

@Entity
@Table(name = "table_name")
class WhateverNameYouWant {
    ...

Instead of simply using the @Entity annotation.

What was weird for me, is that the class it was trying to convert to didn't exist. This worked for me.

I had the same issue. My mistake was that I used @Service annotation on the Service Interface. The @Service annotation should be applied to the ServiceImpl class.

Please make sure that you have added the dependency in pom.xml or gradle file

spring-boot-starter-data-jpa

For me worked a clean install on pom.xml

1. right click on pom.xml

2. expand Run As

3. select Maven build

4. set Goals to the command clean install

5. apply > run > close

Maybe this would perform a bit better in case greater amount of input data does not contain your wanted piece because except has greater cost.

def return_first_match(text):
    result = re.findall('\d+',text)
    result = result[0] if result else ""
    return result

If you want to sort data either in Ascending or Descending order based on particular column, using sequlize js, use the order method of sequlize as follows

// Will order the specified column by descending order
order: sequelize.literal('column_name order')
e.g. order: sequelize.literal('timestamp DESC')

You are using Python 2 methodology instead of Python 3.

Change:

outfile=open('./immates.csv','wb')

To:

outfile=open('./immates.csv','w')

and you will get a file with the following output:

SNo,States,Dist,Population
1,Andhra Pradesh,13,49378776
2,Arunachal Pradesh,16,1382611
3,Assam,27,31169272
4,Bihar,38,103804637
5,Chhattisgarh,19,25540196
6,Goa,2,1457723
7,Gujarat,26,60383628
.....

In Python 3 csv takes the input in text mode, whereas in Python 2 it took it in binary mode.

Edited to Add

Here is the code I ran:

url='http://www.mapsofindia.com/districts-india/'
html = urllib.request.urlopen(url).read()
soup = BeautifulSoup(html)
table=soup.find('table', attrs={'class':'tableizer-table'})
list_of_rows=[]
for row in table.findAll('tr')[1:]:
    list_of_cells=[]
    for cell in row.findAll('td'):
        list_of_cells.append(cell.text)
    list_of_rows.append(list_of_cells)
outfile = open('./immates.csv','w')
writer=csv.writer(outfile)
writer.writerow(['SNo', 'States', 'Dist', 'Population'])
writer.writerows(list_of_rows)

I have solved this issue by following steps:

1. Go to cordova.gradle file (platform/android/cordovaLib/cordova.gradle)
2. Search for getAndroidSdkDir() method
3. Now simply replace System.getenv("ANDROID_HOME") with your real Android SDK path

You really want to do this

flog.write("\nCompany Name: "+ pCompanyName.encode('utf-8'))

This is the "encode late" strategy described in this unicode presentation (slides 32 through 35).

The problem is that your regex is a string, but html is bytes:

>>> type(html)
<class 'bytes'>

Since python doesn't know how those bytes are encoded, it throws an exception when you try to use a string regex on them.

You can either decode the bytes to a string:

html = html.decode('ISO-8859-1')  # encoding may vary!
title = re.findall(pattern, html)  # no more error

Or use a bytes regex:

regex = rb'<title>(,+?)</title>'
#        ^

In this particular context, you can get the encoding from the response headers:

with urllib.request.urlopen(url) as response:
    encoding = response.info().get_param('charset', 'utf8')
    html = response.read().decode(encoding)

See the urlopen documentation for more details.

The fetch mode will only work when selecting the object by id i.e. using entityManager.find(). Since Spring Data will always create a query, the fetch mode configuration will have no use to you. You can either use dedicated queries with fetch joins or use entity graphs.

When you want best performance, you should select only the subset of the data you really need. To do this, it is generally recommended to use a DTO approach to avoid unnecessary data to be fetched, but that usually results in quite a lot of error prone boilerplate code, since you need define a dedicated query that constructs your DTO model via a JPQL constructor expression.

Spring Data projections can help here, but at some point you will need a solution like Blaze-Persistence Entity Views which makes this pretty easy and has a lot more features in it's sleeve that will come in handy! You just create a DTO interface per entity where the getters represent the subset of data you need. A solution to your problem could look like this

@EntityView(Identified.class)
public interface IdentifiedView {
    @IdMapping
    Integer getId();
}

@EntityView(Identified.class)
public interface UserView extends IdentifiedView {
    String getName();
}

@EntityView(Identified.class)
public interface StateView extends IdentifiedView {
    String getName();
}

@EntityView(Place.class)
public interface PlaceView extends IdentifiedView {
    UserView getAuthor();
    CityView getCity();
}

@EntityView(City.class)
public interface CityView extends IdentifiedView {
    StateView getState();
}

public interface PlaceRepository extends JpaRepository<Place, Long>, PlaceRepositoryCustom {
    PlaceView findById(int id);
}

public interface UserRepository extends JpaRepository<User, Long> {
    List<UserView> findAllByOrderByIdAsc();
    UserView findById(int id);
}

public interface CityRepository extends JpaRepository<City, Long>, CityRepositoryCustom {    
    CityView findById(int id);
}

My answer does not require any additional libraries, and it's easy to understand. But you have to notice that if there's more than one number inside a string, my code will concatenate them together.

def search_number_string(string):
    index_list = []
    del index_list[:]
    for i, x in enumerate(string):
        if x.isdigit() == True:
            index_list.append(i)
    start = index_list[0]
    end = index_list[-1] + 1
    number = string[start:end]
    return number

I have no idea why the other answers didn't work for me (error 500) but this works

@GetMapping("")
public String getAll() {
    List<Entity> entityList = entityManager.findAll();
    List<JSONObject> entities = new ArrayList<JSONObject>();
    for (Entity n : entityList) {
        JSONObject Entity = new JSONObject();
        entity.put("id", n.getId());
        entity.put("address", n.getAddress());
        entities.add(entity);
    }
    return entities.toString();
}

AFAIK, I don't think this is possible with a direct method naming query. You can however use the built in sorting mechanism, using the Sort class. The repository has a findAll(Sort) method that you can pass an instance of Sort to. For example:

import org.springframework.data.domain.Sort;

@Repository
public class StudentServiceImpl implements StudentService {
    @Autowired
    private StudentDAO studentDao;

    @Override
    public List<Student> findAll() {
        return studentDao.findAll(sortByIdAsc());
    }

    private Sort sortByIdAsc() {
        return new Sort(Sort.Direction.ASC, "id");
    }
} 

I found this page very useful

https://code.google.com/p/spring-finance-manager/source/browse/trunk/src/main/java/net/stsmedia/financemanager/dao/GenericDAOWithJPA.java?r=2

public abstract class GenericDAOWithJPA<T, ID extends Serializable> {

    private Class<T> persistentClass;

    //This you might want to get injected by the container
    protected EntityManager entityManager;

    @SuppressWarnings("unchecked")
    public GenericDAOWithJPA() {
            this.persistentClass = (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0];
    }

    @SuppressWarnings("unchecked")
    public List<T> findAll() {
            return entityManager.createQuery("Select t from " + persistentClass.getSimpleName() + " t").getResultList();
    }
}

Here is working example for a generic <table>. (question links-broken)

Extracting the table from here countries by GDP (Gross Domestic Product).

htmltable = soup.find('table', { 'class' : 'table table-striped' })
# where the dictionary specify unique attributes for the 'table' tag

The tableDataText function parses a html segment started with tag <table> followed by multiple <tr> (table rows) and inner <td> (table data) tags. It returns a list of rows with inner columns. Accepts only one <th> (table header/data) in the first row.

def tableDataText(table):       
    rows = []
    trs = table.find_all('tr')
    headerow = [td.get_text(strip=True) for td in trs[0].find_all('th')] # header row
    if headerow: # if there is a header row include first
        rows.append(headerow)
        trs = trs[1:]
    for tr in trs: # for every table row
        rows.append([td.get_text(strip=True) for td in tr.find_all('td')]) # data row
    return rows

Using it we get (first two rows).

list_table = tableDataText(htmltable)
list_table[:2]

[['Rank',
  'Name',
  "GDP (IMF '19)",
  "GDP (UN '16)",
  'GDP Per Capita',
  '2019 Population'],
 ['1',
  'United States',
  '21.41 trillion',
  '18.62 trillion',
  '$65,064',
  '329,064,917']]

That can be easily transformed in a pandas.DataFrame for more advanced tools.

import pandas as pd
dftable = pd.DataFrame(list_table[1:], columns=list_table[0])
dftable.head(4)

As MRA said, you shouldn't try to dodge a 429 Too Many Requests but instead handle it accordingly. You have several options depending on your use-case:

1) Sleep your process. The server usually includes a Retry-after header in the response with the number of seconds you are supposed to wait before retrying. Keep in mind that sleeping a process might cause problems, e.g. in a task queue, where you should instead retry the task at a later time to free up the worker for other things.

2) Exponential backoff. If the server does not tell you how long to wait, you can retry your request using increasing pauses in between. The popular task queue Celery has this feature built right-in.

3) Token bucket. This technique is useful if you know in advance how many requests you are able to make in a given time. Each time you access the API you first fetch a token from the bucket. The bucket is refilled at a constant rate. If the bucket is empty, you know you'll have to wait before hitting the API again. Token buckets are usually implemented on the other end (the API) but you can also use them as a proxy to avoid ever getting a 429 Too Many Requests. Celery's rate_limit feature uses a token bucket algorithm.

Here is an example of a Python/Celery app using exponential backoff and rate-limiting/token bucket:

class TooManyRequests(Exception):
"""Too many requests"""

@task(
   rate_limit='10/s',
   autoretry_for=(ConnectTimeout, TooManyRequests,),
   retry_backoff=True)
def api(*args, **kwargs):
  r = requests.get('placeholder-external-api')

  if r.status_code == 429:
    raise TooManyRequests()

I have found a solution that works fine for nested model and array using native JavaScript functions.

var results = [{},{},...]; //your result data returned from sequelize query
var jsonString = JSON.stringify(results); //convert to string to remove the sequelize specific meta data

var obj = JSON.parse(jsonString); //to make plain json
// do whatever you want to do with obj as plain json

What does res.render do and what does the html file look like?

res.render() function compiles your template (please don't use ejs), inserts locals there, and creates html output out of those two things.

Answering Edit 2 part.

// here you set that all templates are located in `/views` directory
app.set('views', __dirname + '/views');

// here you set that you're using `ejs` template engine, and the
// default extension is `ejs`
app.set('view engine', 'ejs');

// here you render `orders` template
response.render("orders", {orders: orders_json});

So, the template path is views/ (first part) + orders (second part) + .ejs (third part) === views/orders.ejs

Anyway, express.js documentation is good for what it does. It is API reference, not a "how to use node.js" book.

String based operators will be deprecated in the future (You've probably seen the warning in console).

Getting this to work with symbolic operators was quite confusing for me, and I've updated the docs with two examples.

Post.findAll({
  where: {
    [Op.or]: [{authorId: 12}, {authorId: 13}]
  }
});
// SELECT * FROM post WHERE authorId = 12 OR authorId = 13;

Post.findAll({
  where: {
    authorId: {
      [Op.or]: [12, 13]
    }
  }
});
// SELECT * FROM post WHERE authorId = 12 OR authorId = 13;

@Query("SELECT rd FROM ReleaseDateType rd, CacheMedia cm WHERE ...")

If your project used Spring-Boot ,you can try to add this annotations at your Application.java.

@EnableJpaRepositories(repositoryFactoryBeanClass=CustomRepositoryFactoryBean.class)
@SpringBootApplication

public class Application {.....

I would do something like,

Main

var getPage = get_page
func get_page (...

func downloader() {
    dl_slots = make(chan bool, DL_SLOT_AMOUNT) // Init the download slot semaphore
    content := getPage(BASE_URL)
    links_regexp := regexp.MustCompile(LIST_LINK_REGEXP)
    matches := links_regexp.FindAllStringSubmatch(content, -1)
    for _, match := range matches{
        go serie_dl(match[1], match[2])
    }
}

Test

func TestDownloader (t *testing.T) {
    origGetPage := getPage
    getPage = mock_get_page
    defer func() {getPage = origGatePage}()
    // The rest to be written
}

// define mock_get_page and rest of the codes
func mock_get_page (....

And I would avoid _ in golang. Better use camelCase

You can't without an iteration.

Option 1

Carnet findCarnet(String codeIsIn) {
    for(Carnet carnet : listCarnet) {
        if(carnet.getCodeIsIn().equals(codeIsIn)) {
            return carnet;
        }
    }
    return null;
}

Option 2

Override the equals() method of Carnet.

Option 3

Storing your List as a Map instead, using codeIsIn as the key:

HashMap<String, Carnet> carnets = new HashMap<>();
// setting map
Carnet carnet = carnets.get(codeIsIn);

I use an alternative to the solution that wrote nifr.

$resultRows = $repository->fetchAll();
uasort($resultRows, function($a, $b){
    if ($a->getProperty() == $b->getProperty()) {
        return 0;
    }
    return ($a->getProperty()< $b->getProperty()) ? -1 : 1;
});

It's quicker than the ORDER BY clause, and without the overhead of the Iterator.

soup = BeautifulSoup(html)
for hit in soup.findAll(attrs={'class' : 'MYCLASS'}):
  hit = hit.text.strip()
  print hit

This will print: THIS IS MY TEXT Try this..

This is probably because of mod_security or some similar server security feature which blocks known spider/bot user agents (urllib uses something like python urllib/3.3.0, it's easily detected). Try setting a known browser user agent with:

from urllib.request import Request, urlopen

req = Request('http://www.cmegroup.com/trading/products/#sortField=oi&sortAsc=false&venues=3&page=1&cleared=1&group=1', headers={'User-Agent': 'Mozilla/5.0'})
webpage = urlopen(req).read()

This works for me.

By the way, in your code you are missing the () after .read in the urlopen line, but I think that it's a typo.

TIP: since this is exercise, choose a different, non restrictive site. Maybe they are blocking urllib for some reason...

lines is a list of strings, re.findall doesn't work with that. try:

import re, sys

f = open('findallEX.txt', 'r')
lines = f.read()
match = re.findall('[A-Z]+', lines)
print match

ElementTree is not too smart about namespaces. You need to give the .find(), findall() and iterfind() methods an explicit namespace dictionary. This is not documented very well:

namespaces = {'owl': 'http://www.w3.org/2002/07/owl#'} # add more as needed

root.findall('owl:Class', namespaces)

Prefixes are only looked up in the namespaces parameter you pass in. This means you can use any namespace prefix you like; the API splits off the owl: part, looks up the corresponding namespace URL in the namespaces dictionary, then changes the search to look for the XPath expression {http://www.w3.org/2002/07/owl}Class instead. You can use the same syntax yourself too of course:

root.findall('{http://www.w3.org/2002/07/owl#}Class')

If you can switch to the lxml library things are better; that library supports the same ElementTree API, but collects namespaces for you in a .nsmap attribute on elements.

EntityFunctions is obsolete. Consider using DbFunctions instead.

var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
   .Where(x => DbFunctions.TruncateTime(x.DateTimeStart) == currentDate.Date);

You have two options; either handle the exception or test the length:

if len(dlist) > 1:
    newlist.append(dlist[1])
    continue

or

try:
    newlist.append(dlist[1])
except IndexError:
    pass
continue

Use the first if there often is no second item, the second if there sometimes is no second item.

All the above answers really help me to construct my answer, because of this I voted for all the answers that other users put it out: But I finally put together my own answer to exact problem I was dealing with:

As question clearly defined I had to access some of the siblings and its children in a dom structure: This solution will iterate over the images in the dom structure and construct image name using product title and save the image to the local directory.

import urlparse
from urllib2 import urlopen
from urllib import urlretrieve
from BeautifulSoup import BeautifulSoup as bs
import requests

def getImages(url):
    #Download the images
    r = requests.get(url)
    html = r.text
    soup = bs(html)
    output_folder = '~/amazon'
    #extracting the images that in div(s)
    for div in soup.findAll('div', attrs={'class':'image'}):
        modified_file_name = None
        try:
            #getting the data div using findNext
            nextDiv =  div.findNext('div', attrs={'class':'data'})
            #use findNext again on previous object to get to the anchor tag
            fileName = nextDiv.findNext('a').text
            modified_file_name = fileName.replace(' ','-') + '.jpg'
        except TypeError:
            print 'skip'
        imageUrl = div.find('img')['src']
        outputPath = os.path.join(output_folder, modified_file_name)
        urlretrieve(imageUrl, outputPath)

if __name__=='__main__':
    url = r'http://www.amazon.com/s/ref=sr_pg_1?rh=n%3A172282%2Ck%3Adigital+camera&keywords=digital+camera&ie=UTF8&qid=1343600585'
    getImages(url)

sed doesn't recognize \d, use [[:digit:]] instead. You will also need to escape the + or use the -r switch (-E on OS X).

Note that [0-9] works as well for Arabic-Hindu numerals.

This is a pretty old thread, but there is a work-around solution now, which may not have been in BeautifulSoup at the time.

Here is an example of what I did. I use the "requests" module to read an RSS feed and get its text content in a variable called "rss_text". With that, I run it thru BeautifulSoup, search for the xpath /rss/channel/title, and retrieve its contents. It's not exactly XPath in all its glory (wildcards, multiple paths, etc.), but if you just have a basic path you want to locate, this works.

from bs4 import BeautifulSoup
rss_obj = BeautifulSoup(rss_text, 'xml')
cls.title = rss_obj.rss.channel.title.get_text()

 public List<Model> getAllData(Pageable pageable){
       List<Model> models= new ArrayList<>();
       modelRepository.findAllByOrderByIdDesc(pageable).forEach(models::add);
       return models;
   }

This is your safest way to do it:

$id =101;
//$user_id=25;
$criteria=new CDbCriteria;
$criteria->condition="email_id < :email_id";
//$criteria->addCondition("user_id=:user_id");
$criteria->params=array(
  ':email_id' => $id,
  //':user_id' => $user_id,
);
$comments=EmailArchive::model()->findAll($criteria);

Note that if you comment out the commented lines you get a way to add more filtering to your search.

After this it is recommend to check if there is any data returned like:

if (isset($comments)) { // We found some comments, we can sleep well tonight
  // do comments process or whatever
}

I am days into the MVC4 world.

For what its worth, I have a SitesAPIController, and I needed a custom method, that could be called like:

http://localhost:9000/api/SitesAPI/Disposition/0

With different values for the last parameter to get record with different dispositions.

What Finally worked for me was:

The method in the SitesAPIController:

// GET api/SitesAPI/Disposition/1
[ActionName("Disposition")]
[HttpGet]
public Site Disposition(int disposition)
{
    Site site = db.Sites.Where(s => s.Disposition == disposition).First();
    return site;
}

And this in the WebApiConfig.cs

// this was already there
config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

// this i added
config.Routes.MapHttpRoute(
    name: "Action",
    routeTemplate: "api/{controller}/{action}/{disposition}"
 );

For as long as I was naming the {disposition} as {id} i was encountering:

{
"Message": "No HTTP resource was found that matches the request URI 'http://localhost:9000/api/SitesAPI/Disposition/0'.",
"MessageDetail": "No action was found on the controller 'SitesAPI' that matches the request."
}

When I renamed it to {disposition} it started working. So apparently the parameter name is matched with the value in the placeholder.

Feel free to edit this answer to make it more accurate/explanatory.

2. Open the python editor IDLE from the menu, and open xxxx.py, then press F5 to run it.

For your posted code, the error is at this line:

def main(url, out_folder="C:\asdf\"):

It should be:

def main(url, out_folder="C:\\asdf\\"):

In addition to the accepted answer. You can use a lambda instead of regex:

from bs4 import BeautifulSoup

html = """<p>test python</p>"""

soup = BeautifulSoup(html, "html.parser")

print(soup(text="python"))
print(soup(text=lambda t: "python" in t))

Output:

[]
['test python']

Just pass it as an argument of findAll:

>>> from BeautifulSoup import BeautifulSoup
>>> soup = BeautifulSoup("""
... <html>
... <head><title>My Title!</title></head>
... <body><table>
... <tr><td>First!</td>
... <td valign="top">Second!</td></tr>
... </table></body><html>
... """)
>>>
>>> soup.findAll('td')
[<td>First!</td>, <td valign="top">Second!</td>]
>>>
>>> soup.findAll('td', valign='top')
[<td valign="top">Second!</td>]

For anyone using Sequelize version 3 and above, use:

Model.destroy({
    where: {
        // criteria
    }
})

you can replace your pattern with

regex = ur"\[P\]([\w\s]+)\[\/P\]"

The reason behind this error is : Flask app is already running, hasn't shut down and in middle of that we try to start another instance by: with app.app_context(): #Code Before we use this with statement we need to make sure that scope of the previous running app is closed.

A referral is sent by an AD server when it doesn't have the information requested itself, but know that another server have the info. It usually appears in trust environment where a DC can refer to a DC in trusted domain.

In your case you are only specifying a domain, relying on automatic lookup of what domain controller to use. I think that you should try to find out what domain controller is used for the query and look if that one really holds the requested information.

If you provide more information on your AD setup, including any trusts/subdomains, global catalogues and the DNS resource records for the domain controllers it will be easier to help you.

For the less specific case (not just the code in the question - since this is one of the first results in Google for this generic error message. This error also occurs when running certain os command with None argument.

For example:

os.path.exists(arg)  
os.stat(arg)

Will raise this exception when arg is None.

public List<Student> findStudentByReports(Date startDate, Date endDate) {
    System.out.println("call findStudentMethd******************with this pattern"
                    + startDate
                    + endDate
                    + "*********************************************");

    return em
            .createQuery(
                    "' select attendence from Attendence attendence where attendence.admissionDate BETWEEN : startDate '' AND endDate ''"
                            + "'")
            .setParameter("startDate", startDate, TemporalType.DATE)

Your second delegate is not a rewrite of the first in anonymous delegate (rather than lambda) format. Look at your conditions.

First:

x.ID == packageId || x.Parent.ID == packageId || x.Parent.Parent.ID == packageId

Second:

(x.ID == packageId) || (x.Parent != null && x.Parent.ID == packageId) || 
(x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)

The call to the lambda would throw an exception for any x where the ID doesn't match and either the parent is null or doesn't match and the grandparent is null. Copy the null checks into the lambda and it should work correctly.

Edit after Comment to Question

If your original object is not a List<T>, then we have no way of knowing what the return type of FindAll() is, and whether or not this implements the IQueryable interface. If it does, then that likely explains the discrepancy. Because lambdas can be converted at compile time into an Expression<Func<T>> but anonymous delegates cannot, then you may be using the implementation of IQueryable when using the lambda version but LINQ-to-Objects when using the anonymous delegate version.

This would also explain why your lambda is not causing a NullReferenceException. If you were to pass that lambda expression to something that implements IEnumerable<T> but not IQueryable<T>, runtime evaluation of the lambda (which is no different from other methods, anonymous or not) would throw a NullReferenceException the first time it encountered an object where ID was not equal to the target and the parent or grandparent was null.

Added 3/16/2011 8:29AM EDT

Consider the following simple example:

IQueryable<MyObject> source = ...; // some object that implements IQueryable<MyObject>

var anonymousMethod =  source.Where(delegate(MyObject o) { return o.Name == "Adam"; });    
var expressionLambda = source.Where(o => o.Name == "Adam");

These two methods produce entirely different results.

The first query is the simple version. The anonymous method results in a delegate that's then passed to the IEnumerable<MyObject>.Where extension method, where the entire contents of source will be checked (manually in memory using ordinary compiled code) against your delegate. In other words, if you're familiar with iterator blocks in C#, it's something like doing this:

public IEnumerable<MyObject> MyWhere(IEnumerable<MyObject> dataSource, Func<MyObject, bool> predicate)
{
    foreach(MyObject item in dataSource)
    {
        if(predicate(item)) yield return item;
    }
}

The salient point here is that you're actually performing your filtering in memory on the client side. For example, if your source were some SQL ORM, there would be no WHERE clause in the query; the entire result set would be brought back to the client and filtered there.

The second query, which uses a lambda expression, is converted to an Expression<Func<MyObject, bool>> and uses the IQueryable<MyObject>.Where() extension method. This results in an object that is also typed as IQueryable<MyObject>. All of this works by then passing the expression to the underlying provider. This is why you aren't getting a NullReferenceException. It's entirely up to the query provider how to translate the expression (which, rather than being an actual compiled function that it can just call, is a representation of the logic of the expression using objects) into something it can use.

An easy way to see the distinction (or, at least, that there is) a distinction, would be to put a call to AsEnumerable() before your call to Where in the lambda version. This will force your code to use LINQ-to-Objects (meaning it operates on IEnumerable<T> like the anonymous delegate version, not IQueryable<T> like the lambda version currently does), and you'll get the exceptions as expected.

TL;DR Version

The long and the short of it is that your lambda expression is being translated into some kind of query against your data source, whereas the anonymous method version is evaluating the entire data source in memory. Whatever is doing the translating of your lambda into a query is not representing the logic that you're expecting, which is why it isn't producing the results you're expecting.

Alternatively we can use lxml, it support xpath and very fast!

from lxml import html, etree 

attr = html.fromstring(html_text)#passing the raw html
handles = attr.xpath('//div[@class="stylelistrow"]')#xpath exresssion to find that specific class

for each in handles:
    print(etree.tostring(each))#printing the html as string

I was getting the same the error inside a shared function, but it was only happening for some calls to this shared function. I eventually realized that one of classes calling the shared function wasn't wrapping it inside of a Unit of Work. Once I updated this classes functions with a Unit of Work everything worked as expected.

So just posting this for any future visitors who run into this same error, but for whom the accepted answer doesn't apply.

Get a list of number as input from the user.

This can be done by using list in python.

L=list(map(int,input(),split()))

Here L indicates list, map is used to map input with the position, int specifies the datatype of the user input which is in integer datatype, and split() is used to split the number based on space.

You should use System.DirectoryServices.AccountManagement. It's much easier. Here is a nice code project article giving you an overview on all the classes in this DLL.

As you pointed out, your current approach doesn't find out the primary group. Actually, it's much worse than you thought. There are some more cases that it doesn't work, like the domain local group from another domain. You can check here for details. Here is how the code looks like if you switch to use System.DirectoryServices.AccountManagement. The following code can find the immediate groups this user assigned to, which includes the primary group.

UserPrincipal user = UserPrincipal.FindByIdentity(new PrincipalContext (ContextType.Domain, "mydomain.com"), IdentityType.SamAccountName, "username");
foreach (GroupPrincipal group in user.GetGroups())
{
    Console.Out.WriteLine(group);
}

I had a similar problem, I needed the index of the item but it had to be case insensitive, i looked around the web for a few minutes and found nothing, so I just wrote a small method to get it done, here is what I did:

private static int getCaseInvariantIndex(List<string> ItemsList, string searchItem)
{
    List<string> lowercaselist = new List<string>();

    foreach (string item in ItemsList)
    {
        lowercaselist.Add(item.ToLower());
    }

    return lowercaselist.IndexOf(searchItem.ToLower());
}

Add this code to the same file, and call it like this:

int index = getCaseInvariantIndexFromList(ListOfItems, itemToFind);

Hope this helps, good luck!

I wanted to add more details about how the @Valid works, especially in spring.

Everything you'd want to know about validation in spring is explained clearly and in detail in https://reflectoring.io/bean-validation-with-spring-boot/, but I'll copy the answer to how @Valid works incase the link goes down.

The @Valid annotation can be added to variables in a rest controller method to validate them. There are 3 types of variables that can be validated:

• the request body,
• variables within the path (e.g. id in /foos/{id}) and,
• query parameters.

So now... how does spring "validate"? You can define constraints to the fields of a class by annotating them with certain annotations. Then, you pass an object of that class into a Validator which checks if the constraints are satisfied.

For example, suppose I had controller method like this:

@RestController
class ValidateRequestBodyController {

  @PostMapping("/validateBody")
  ResponseEntity<String> validateBody(@Valid @RequestBody Input input) {
    return ResponseEntity.ok("valid");
  }

}

So this is a POST request which takes in a response body, and we're mapping that response body to a class Input.

Here's the class Input:

class Input {

  @Min(1)
  @Max(10)
  private int numberBetweenOneAndTen;

  @Pattern(regexp = "^[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}$")
  private String ipAddress;
  
  // ...
}

The @Valid annotation will tell spring to go and validate the data passed into the controller by checking to see that the integer numberBetweenOneAndTen is between 1 and 10 inclusive because of those min and max annotations. It'll also check to make sure the ip address passed in matches the regular expression in the annotation.

side note: the regular expression isn't perfect.. you could pass in 3 digit numbers that are greater than 255 and it would still match the regular expression.

Here's an example of validating a query variable and path variable:

@RestController
@Validated
class ValidateParametersController {

  @GetMapping("/validatePathVariable/{id}")
  ResponseEntity<String> validatePathVariable(
      @PathVariable("id") @Min(5) int id) {
    return ResponseEntity.ok("valid");
  }
  
  @GetMapping("/validateRequestParameter")
  ResponseEntity<String> validateRequestParameter(
      @RequestParam("param") @Min(5) int param) { 
    return ResponseEntity.ok("valid");
  }
}

In this case, since the query variable and path variable are just integers instead of just complex classes, we put the constraint annotation @Min(5) right on the parameter instead of using @Valid.

Use String.prototype.match.

Here is an example from the MDN docs itself:

var str = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz';
var regexp = /[A-E]/gi;
var matches_array = str.match(regexp);

console.log(matches_array);
// ['A', 'B', 'C', 'D', 'E', 'a', 'b', 'c', 'd', 'e']

.find_all() returns list of all found elements, so:

input_tag = soup.find_all(attrs={"name" : "stainfo"})

input_tag is a list (probably containing only one element). Depending on what you want exactly you either should do:

output = input_tag[0]['value']

or use .find() method which returns only one (first) found element:

input_tag = soup.find(attrs={"name": "stainfo"})
output = input_tag['value']

import urllib
from bs4 import BeautifulSoup

url = "https://www.yahoo.com"
html = urllib.urlopen(url).read()
soup = BeautifulSoup(html)

# kill all script and style elements
for script in soup(["script", "style"]):
    script.extract()    # rip it out

# get text
text = soup.get_text()

# break into lines and remove leading and trailing space on each
lines = (line.strip() for line in text.splitlines())
# break multi-headlines into a line each
chunks = (phrase.strip() for line in lines for phrase in line.split("  "))
# drop blank lines
text = '\n'.join(chunk for chunk in chunks if chunk)

print(text.encode('utf-8'))

The same error occurs if in DirectoryEntry.Patch is nothing after the symbols "LDAP//:". It is necessary to check the directoryEntry.Path before directorySearcher.FindOne(). Unless explicitly specified domain, and do not need to "LDAP://".

private void GetUser(string userName, string domainName)
{
     DirectoryEntry dirEntry = new DirectoryEntry();

     if (domainName.Length > 0)
     {
          dirEntry.Path = "LDAP://" + domainName;
     }

     DirectorySearcher dirSearcher = new DirectorySearcher(dirEntry);
     dirSearcher.SearchScope = SearchScope.Subtree;
     dirSearcher.Filter = string.Format("(&(objectClass=user)(|(cn={0})(sn={0}*)(givenName={0})(sAMAccountName={0}*)))", userName);
     var searchResults = dirSearcher.FindAll();
     //var searchResults = dirSearcher.FindOne();

     if (searchResults.Count == 0)
     {
          MessageBox.Show("User not found");
     }
     else
     {
          foreach (SearchResult sr in searchResults)
          {
              var de = sr.GetDirectoryEntry();
              string user = de.Properties["SAMAccountName"][0].ToString();
              MessageBox.Show(user); 
          }        
     }
}

Well, if you know where your user lives in the AD hierarchy (e.g. quite possibly in the "Users" container, if it's a small network), you could also bind to the user account directly, instead of searching for it.

DirectoryEntry deUser = new DirectoryEntry("LDAP://cn=John Doe,cn=Users,dc=yourdomain,dc=com");

if (deUser != null)
{
  ... do something with your user
}

And if you're on .NET 3.5 already, you could even use the vastly expanded System.DirectorySrevices.AccountManagement namespace with strongly typed classes for each of the most common AD objects:

// bind to your domain
PrincipalContext pc = new PrincipalContext(ContextType.Domain, "LDAP://dc=yourdomain,dc=com");

// find the user by identity (or many other ways)
UserPrincipal user = UserPrincipal.FindByIdentity(pc, "cn=John Doe");

There's loads of information out there on System.DirectoryServices.AccountManagement - check out this excellent article on MSDN by Joe Kaplan and Ethan Wilansky on the topic.

This is how I do it, useful for simple custom objects to which you keep adding attributes:

Given an object created with obj = type("Obj",(object,),{}), or by simply:

class Obj: pass
obj = Obj()

Add some attributes:

obj.name = 'gary'
obj.age = 32

then, to obtain a dictionary with only the custom attributes:

{key: value for key, value in obj.__dict__.items() if not key.startswith("__")}

# {'name': 'gary', 'age': 32}

Microsoft guidelines as checked by FxCop discourage use of List<T> in public APIs - prefer IList<T>.

Incidentally, I now almost always declare one-dimensional arrays as IList<T>, which means I can consistently use the IList<T>.Count property rather than Array.Length. For example:

public interface IMyApi
{
    IList<int> GetReadOnlyValues();
}

public class MyApiImplementation : IMyApi
{
    public IList<int> GetReadOnlyValues()
    {
        List<int> myList = new List<int>();
        ... populate list
        return myList.AsReadOnly();
    }
}
public class MyMockApiImplementationForUnitTests : IMyApi
{
    public IList<int> GetReadOnlyValues()
    {
        IList<int> testValues = new int[] { 1, 2, 3 };
        return testValues;
    }
}

You may want to take a look at GemBox.Spreadsheet.

They have a free version with all features but limited to 150 rows per sheet and 5 sheets per workbook, if that falls within your needs.

I haven't had need to use it myself yet, but does look interesting.

GetLogicalDrives() enumerates all mounted disk partitions, not physical drives.

You can enumerate the drive letters with (or without) GetLogicalDrives, then call QueryDosDevice() to find out which physical drive the letter is mapped to.

Alternatively, you can decode the information in the registry at HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices. The binary data encodings there are not obvious, however. If you have a copy of Russinovich and Solomon's book Microsoft Windows Internals, this registry hive is discussed in Chapter 10.

Shortest, but not supported by Internet Explorer 8 and earlier:

new Date().toJSON()

I feel like none of these messages quite answer the question still. See - https://api.slack.com/docs/message-attachments.

It requires you to put the link in an attachment. Hyperlinking is still not allowed in the body of the message.

{ "attachments": [ { ..., "text": " <https://honeybadger.io/path/to/event/|ReferenceError> - UI is not defined", ... ] }

ReferenceError will be a hyperlink.

if ($('a').on('Clicked').text().search('1') == -1)
{
    //Page == 1
}
else
{
    //Page != 1
}

You can try

sed 's:\\:\/:g'`

The first \ is to insert an input, the second \ will be the one you want to substitute.

So it is 's ":" First Slash "\" second slash "\" ":" "\" to insert input "/" as the new slash that will be presented ":" g'

\\ \/ 

And that's it. It will work.

You can't compare two Integer with a simple == they're objects so most of the time references won't be the same.

There is a trick, with Integer between -128 and 127, references will be the same as autoboxing uses Integer.valueOf() which caches small integers.

If the value p being boxed is true, false, a byte, a char in the range \u0000 to \u007f, or an int or short number between -128 and 127, then let r1 and r2 be the results of any two boxing conversions of p. It is always the case that r1 == r2.

Gradle looks for gradle.properties files in these places:

• in project build dir (that is where your build script is)
• in sub-project dir
• in gradle user home (defined by the GRADLE_USER_HOME environment variable, which if not set defaults to USER_HOME/.gradle)

Properties from one file will override the properties from the previous ones (so file in gradle user home has precedence over the others, and file in sub-project has precedence over the one in project root).

Updated answer: Constraint Layout

It seems that the trend in Android now is to use a Constraint layout. Although it is simple enough to center a view using a RelativeLayout (as other answers have shown), the ConstraintLayout is more powerful than the RelativeLayout for more complex layouts. So it is worth learning how do do now.

To center a view, just drag the handles to all four sides of the parent.

Already posted answers are for csv and other one is by Interop dll where you need to install excel over the server, every approach has its own pros and cons. Here is an option which will give you

1. Perfect excel output [not csv]
2. With perfect excel and your data type match
3. Without excel installation
4. Pass list and get Excel output :)

you can achieve this by using NPOI DLL, available for both .net as well as for .net core

Steps :

1. Import NPOI DLL
2. Add Section 1 and 2 code provided below
3. Good to go

Section 1

This code performs below task :

1. Creating New Excel object - _workbook = new XSSFWorkbook();
2. Creating New Excel Sheet object - _sheet =_workbook.CreateSheet(_sheetName);
3. Invokes WriteData() - explained later Finally, creating and
4. returning MemoryStream object

=============================================================================

Now you just need to call WriteData() function by passing your list, and it will provide you your excel.

I have tested it in WEB API and WEB API Core, works like a charm.

use Json & jQuery. It's way easier than oldschool javascript

function savedata1() { 

var obj = $('#myTable tbody tr').map(function() {
var $row = $(this);
var t1 = $row.find(':nth-child(1)').text();
var t2 = $row.find(':nth-child(2)').text();
var t3 = $row.find(':nth-child(3)').text();
return {
    td_1: $row.find(':nth-child(1)').text(),
    td_2: $row.find(':nth-child(2)').text(),
    td_3: $row.find(':nth-child(3)').text()
   };
}).get();

I do it like this, to launch the SendFreeTextActivity from a (custom) menu fragment that appears in multiple activities:

In the MenuFragment class:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_menu, container, false);

    final Button sendFreeTextButton = (Button) view.findViewById(R.id.sendFreeTextButton);
    sendFreeTextButton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            Log.d(TAG, "sendFreeTextButton clicked");
            Intent intent = new Intent(getActivity(), SendFreeTextActivity.class);
            MenuFragment.this.startActivity(intent);
        }
    });
    ...

For simple test project, g++ or make standalone are good options as already answered:

g++ -o hi hi.cpp

or

make hi

For real projects, however, the usage of a project manager is required. At the time I write this answer, the most used and open-source is cmake (an alternative could be QT qmake ).

Following is a simple CMake example:

Make sure you installed cmake on your linux distribution apt-get install cmake or yum install cmake.

Create a file CMakeLists.txt (the name is important) together with your source hi.cpp

project("hi")

add_executable( hi hi.cpp )

Then compile and run as:

cmake .
make
./hi

This allows the project to scale easily with libraries, sources, and much more. It also makes most IDEs to understand the project properly (Most IDEs accept CMake natively, like kdevelop, qtCreator, etc..)

You could also generate Visual-Studio or XCode projects from CMake, in case you decide to port the software to other platforms in the future.

cmake -G Xcode . #will generate `hi.xcodeproj` you can load on macOS

One advantage is that you are compiling access into the application, so it cannot accidentally be changed by someone modifying the Web.config.

This may not be an advantage to you, and might be a disadvantage. But for some kinds of access, it may be preferrable.

Plus, I find that authorization information in the Web.config pollutes it, and makes it harder to find things. So in some ways its preference, in others there is no other way to do it.

I had a similar exception (but different problem) - java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to org.bson.Document , and fortunately it's solved easier:

Instead of

List<Document> docs = obj.get("documents");
Document doc = docs.get(0)

which gives error on second line, One can use

List<Document> docs = obj.get("documents");
Document doc = new Document(docs.get(0));

encodeURIComponent()

Converts the input into a URL-encoded string

encodeURI()

URL-encodes the input, but assumes a full URL is given, so returns a valid URL by not encoding the protocol (e.g. http://) and host name (e.g. www.stackoverflow.com).

decodeURIComponent() and decodeURI() are the opposite of the above

This will show you the table name and column name

select table_name,column_name from information_schema.columns
where column_name like '%breakfast%'

$(function () {
    $('#myTab a:last').tab('show');
});

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
    var target = $(e.target).attr("href");
    if ((target == '#messages')) {
        alert('ok');
    } else {
        alert('not ok');
    }
});

the problem is that attr('href') is never empty.

Or to compare the #id = "#some value" and then call the ajax.

This is to merge selected columns from two tables.

If table_1 contains t1_a,t1_b,t1_c..,id,..t1_z columns, and table_2 contains t2_a, t2_b, t2_c..., id,..t2_z columns, and only t1_a, id, t2_a are required in the final table, then

mergedCSV = table_1[['t1_a','id']].merge(table_2[['t2_a','id']], on = 'id',how = 'left')
# save resulting output file    
mergedCSV.to_csv('output.csv',index = False)

If you are capable of using libraries, you may find that Lo-Dash JS library is quite useful. In this case, go ahead and check _.contains() (replaced by _.includes() as of v4).

(Note Lo-Dash convention is naming the library object _. Don't forget to check installation in the same page to set it up for your project.)

_.contains("foo", "oo");     // ? true
_.contains("foo", "bar");    // ? false
// Equivalent with:
_("foo").contains("oo");     // ? true
_("foo").contains("bar");    // ? false

In your case, go ahead and use:

_.contains(str, "Yes");
// or:
_(str).contains("Yes");

..whichever one you like better.

A couple ways this can be done:

This will make it a square

ul
{
  list-style-type: square;
}

This will make it green

li
{
  color: #0F0;
}

This will prevent the text from being green

li p
{
  color: #000;
}

However that will require that all text within lists be in paragraphs so that the color is not overridden.

A better way is to make an image of a green square and use:

ul
{
  list-style: url(green-square.png);
}

The global scope in React Native is variable global. Such as global.foo = foo, then you can use global.foo anywhere.

But do not abuse it! In my opinion, global scope may used to store the global config or something like that. Share variables between different views, as your description, you can choose many other solutions(use redux,flux or store them in a higher component), global scope is not a good choice.

A good practice to define global variable is to use a js file. For example global.js

global.foo = foo;
global.bar = bar;

Then, to make sure it is executed when project initialized. For example, import the file in index.js:

import './global.js'
// other code

Now, you can use the global variable anywhere, and don't need to import global.js in each file. Try not to modify them!

The development of Unicode was aimed at creating a new standard for mapping the characters in a great majority of languages that are being used today, along with other characters that are not that essential but might be necessary for creating the text. UTF-8 is only one of the many ways that you can encode the files because there are many ways you can encode the characters inside a file into Unicode.

http://www.differencebetween.net/technology/difference-between-unicode-and-utf-8/

I think move would probably be the closest standard cursor value for what you're doing:

move
Indicates something is to be moved.

This works! https://reacttraining.com/react-router/web/api/withRouter

import { withRouter } from 'react-router-dom';

class MyComponent extends React.Component {
  render () {
    this.props.history;
  }
}

withRouter(MyComponent);

You can also use defaultdict to address this situation. It goes something like this:

from collections import defaultdict

#initialises the dictionary with values as list
aTargetDictionary = defaultdict(list)

for aKey in aSourceDictionary:
    aTargetDictionary[aKey].append(aSourceDictionary[aKey])

If you are using jQuery already, your best bet is .outerHeight() or .height(), as has been stated.

Without jQuery, you can check the box-sizing in use and add up various paddings + borders + clientHeight, or you can use getComputedStyle:

var h = getComputedStyle(document.getElementById('someDiv')).height;

h will now be a string like a "53.825px".

And I can't find the reference, but I think I heard getComputedStyle() can be expensive, so it's probably not something you want to call on each window.onscroll event (but then, neither is jQuery's height()).

List screens:

screen -list

Output:

There is a screen on:
23536.pts-0.wdzee       (10/04/2012 08:40:45 AM)        (Detached)
1 Socket in /var/run/screen/S-root.

Kill screen session:

screen -S 23536 -X quit

use this code...

    dt = city.GetAllCity();//your datatable
    string attachment = "attachment; filename=city.xls";
    Response.ClearContent();
    Response.AddHeader("content-disposition", attachment);
    Response.ContentType = "application/vnd.ms-excel";
    string tab = "";
    foreach (DataColumn dc in dt.Columns)
    {
        Response.Write(tab + dc.ColumnName);
        tab = "\t";
    }
    Response.Write("\n");
    int i;
    foreach (DataRow dr in dt.Rows)
    {
        tab = "";
        for (i = 0; i < dt.Columns.Count; i++)
        {
            Response.Write(tab + dr[i].ToString());
            tab = "\t";
        }
        Response.Write("\n");
    }
    Response.End();

Another alternate approach to Diego's is to use a library:

https://github.com/airbnb/DeepLinkDispatch

You can easily declare the URIs you'd like to handle and the parameters you'd like to extract through annotations on the Activity, like:

@DeepLink("path/to/what/i/want")
public class SomeActivity extends Activity {
  ...
}

As a plus, the query parameters will also be passed along to the Activity as well.

>>> bits_in_word=12
>>> int('111111111111',2)-(1<<bits_in_word)
-1

This works because:

The two's complement of a binary number is defined as the value obtained by subtracting the number from a large power of two (specifically, from 2^N for an N-bit two's complement). The two's complement of the number then behaves like the negative of the original number in most arithmetic, and it can coexist with positive numbers in a natural way.

$Date = $row['Received_date']->format('d/m/Y');

then it cast date object from given in database

Just Make a single class like, everything will be fine with this:

        @Component
        @Order(Ordered.HIGHEST_PRECEDENCE)
        public class MyCorsConfig implements Filter {

            @Override
            public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
                final HttpServletResponse response = (HttpServletResponse) res;
                response.setHeader("Access-Control-Allow-Origin", "*");
                response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
                response.setHeader("Access-Control-Allow-Headers", "Authorization, Content-Type, enctype");
                response.setHeader("Access-Control-Max-Age", "3600");
                if (HttpMethod.OPTIONS.name().equalsIgnoreCase(((HttpServletRequest) req).getMethod())) {
                    response.setStatus(HttpServletResponse.SC_OK);
                } else {
                    chain.doFilter(req, res);
                }
            }

            @Override
            public void destroy() {
            }

            @Override
            public void init(FilterConfig config) throws ServletException {
            }
        }

Christopher's Proguard solution is the best, but if for any reason you don't like Proguard, here is a very low-tech solution:

Comment logs:

find . -name "*\.java" | xargs grep -l 'Log\.' | xargs sed -i 's/Log\./;\/\/ Log\./g'

Uncomment logs:

find . -name "*\.java" | xargs grep -l 'Log\.' | xargs sed -i 's/;\/\/ Log\./Log\./g'

A constraint is that your logging instructions must not span over multiple lines.

(Execute these lines in a UNIX shell at the root of your project. If using Windows, get a UNIX layer or use equivalent Windows commands)

Small additional note to @rmag's answer. If you have empty but required fields that you want to make dirty use this:

$scope.myForm.username.$setViewValue($scope.myForm.username.$viewValue !== undefined 
    ? $scope.myForm.username.$viewValue : '');

suggestion here looks like a good candidate for this question as well

Performing click event on a disabled element? Javascript jQuery

jQuery('input#submit').click(function(e) {
    if ( something ) {        
        return false;
    } 
});

I've recently found even more interesting way to create any ValueNode or ContainerNode (Jackson v2.3).

ObjectNode node = JsonNodeFactory.instance.objectNode();

You can do that like this:

General syntax:

selector {
   box-shadow: topBoxShadow, bottomBoxShadow, rightBoxShadow, leftBoxShadow
}

Example: we want to make only a bottom box shadow with red color,

so to do that we have to set all the sides options where we have to set the bottom box shadow options and set all the others as empty as follow:

.box {
     -moz-box-shadow: 0 0 0 transparent ,0 0 10px red, 0 0 0 transparent, 0 0 0 transparent
     -o-box-shadow: 0 0 0 transparent ,0 0 10px red, 0 0 0 transparent, 0 0 0 transparent
     -webkit-box-shadow: 0 0 0 transparent ,0 0 10px red, 0 0 0 transparent, 0 0 0 transparent
     box-shadow: 0 0 0 transparent ,0 0 10px red, 0 0 0 transparent, 0 0 0 transparent
}

Use the following code to check if a folder exists. It works on both Windows & Linux platforms.

#include <stdio.h>
#include <sys/stat.h>

int main(int argc, char* argv[])
{
    const char* folder;
    //folder = "C:\\Users\\SaMaN\\Desktop\\Ppln";
    folder = "/tmp";
    struct stat sb;

    if (stat(folder, &sb) == 0 && S_ISDIR(sb.st_mode)) {
        printf("YES\n");
    } else {
        printf("NO\n");
    }
}

Method that works with arrays, and it works with objects too (beware, objects don't have a guaranteed order!).

I prefer this method the most, because original array is not modified.

// In case of array
var arr = [];
arr[3] = 'first';
arr[7] = 'last';
var firstElement;
for(var i in arr){
    firstElement = arr[i];
    break;
}
console.log(firstElement);  // "first"

// In case of object
var obj = {
    first: 'first',
    last: 'last',
};

var firstElement;

for(var i in obj){
    firstElement = obj[i];
    break;
}

console.log(firstElement) // First;

All the open streams & connections need to be properly closed, so the next time we try to use the urlConnection object, it does not throw an error. As an example, the following code change fixed the error for me.

Before:

OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream());
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(out));
bw.write("Some text");
bw.close();
out.close();

After:

OutputStream os = urlConnection.getOutputStream();
OutputStream out = new BufferedOutputStream(os);
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(out));
bw.write("Some text");
bw.close();
out.close();
os.close(); // This is a must.

Simplify. Cherry-pick the commits. Don't cherry-pick the merge.

Here's a rewrite of the accepted answer that ideally clarifies the advantages/risks of possible approaches:

You're trying to cherry pick fd9f578, which was a merge with two parents.

Instead of cherry-picking a merge, the simplest thing is to cherry pick the commit(s) you actually want from each branch in the merge.

Since you've already merged, it's likely all your desired commits are in your list. Cherry-pick them directly and you don't need to mess with the merge commit.

explanation

The way a cherry-pick works is by taking the diff that a changeset represents (the difference between the working tree at that point and the working tree of its parent), and applying the changeset to your current branch.

If a commit has two or more parents, as is the case with a merge, that commit also represents two or more diffs. The error occurs because of the uncertainty over which diff should apply.

alternatives

If you determine you need to include the merge vs cherry-picking the related commits, you have two options:

1. (More complicated and obscure; also discards history) you can indicate which parent should apply.

   • Use the -m option to do so. For example, git cherry-pick -m 1 fd9f578 will use the first parent listed in the merge as the base.

   • Also consider that when you cherry-pick a merge commit, it collapses all the changes made in the parent you didn't specify to -m into that one commit. You lose all their history, and glom together all their diffs. Your call.

2. (Simpler and more familiar; preserves history) you can use git merge instead of git cherry-pick.

   • As is usual with git merge, it will attempt to apply all commits that exist on the branch you are merging, and list them individually in your git log.

If we also want to handle white spaces and unwanted tabs-

Check and Try the below script (Unit Tested)-

--Declaring
DECLARE @Tbl TABLE(col_1 VARCHAR(100));

--Test Samples
INSERT INTO @Tbl (col_1)
VALUES
('  EY     y            
Salem')
, ('  EY     P    ort       Chennai   ')
, ('  EY     Old           Park   ')
, ('  EY   ')
, ('  EY   ')
,(''),(null),('d                           
    f');

SELECT col_1 AS INPUT,
    LTRIM(RTRIM(
    REPLACE(
    REPLACE(
    REPLACE(
    REPLACE(
    REPLACE(
        REPLACE(
        REPLACE(
        REPLACE(
        REPLACE(
        REPLACE(
        REPLACE(col_1,CHAR(10),' ')
        ,CHAR(11),' ')
        ,CHAR(12),' ')
        ,CHAR(13),' ')
        ,CHAR(14),' ')
        ,CHAR(160),' ')
        ,CHAR(13)+CHAR(10),' ')
    ,CHAR(9),' ')
    ,' ',CHAR(17)+CHAR(18))
    ,CHAR(18)+CHAR(17),'')
    ,CHAR(17)+CHAR(18),' ')
    )) AS [OUTPUT]
FROM @Tbl;

Try:

awk -F',' '{print $3}' myfile.txt

Here in -F you are saying to awk that use "," as field separator.

the css property of <hr> are :

hr {
  -moz-border-bottom-colors: none;
  -moz-border-image: none;
  -moz-border-left-colors: none;
  -moz-border-right-colors: none;
  -moz-border-top-colors: none;
  border-color: #EEEEEE -moz-use-text-color #FFFFFF;
  border-style: solid none;
  border-width: 1px 0;
  margin: 18px 0;
}

It correspond to a 1px horizontal line with a very light grey and vertical margin of 18px.

and because <hr> is inside a <div> without class the width depends on the content of the <div>

if you would like the <hr> to be full width, replace <div> with <div class='row'><div class='span12'> (with according closing tags).

If you expect something different, describe what you expect by adding a comment.

You can use like this also,

<a href="javascript:void(0);" onclick="javascript:window.location.href='mailto:[email protected]'; return false;">[email protected]</a>

I think this is best way to resolved for chrome issues.

Thanks..

$(window).on('load', function () {
  $("#cover").fadeOut(1750);
});

I am trying to push value in an array state and set value like this and define state array and push value by map function.

 this.state = {
        createJob: [],
        totalAmount:Number=0
    }


 your_API_JSON_Array.map((_) => {
                this.setState({totalAmount:this.state.totalAmount += _.your_API_JSON.price})
                this.state.createJob.push({ id: _._id, price: _.your_API_JSON.price })
                return this.setState({createJob: this.state.createJob})
            })

As you said..

$Gender  = isset($_POST["gender"]); ' it returns a empty string 

because, you haven't mention method type either use POST or GET, by default it will use GET method. On the other side, you are trying to retrieve your value by using POST method, but in the form you haven't mentioned POST method. Which means miss-match method will result for empty.

Try this code..

<form name="signup_form"  action="./signup.php" onsubmit="return validateForm()"   method="post">
<table> 
  <tr> <td> First Name    </td><td> <input type="text" name="fname" size=10/></td></tr>
  <tr> <td> Last Name     </td><td> <input type="text" name="lname" size=10/></td></tr>
  <tr> <td> Your Email    </td><td> <input type="text" name="email" size=10/></td></tr>
  <tr> <td> Re-type Email </td><td> <input type="text" name="remail"size=10/></td></tr>
  <tr> <td> Password      </td><td> <input type="password" name="paswod" size=10/> </td></tr>
  <tr> <td> Gender        </td><td> <select name="gender">
  <option value="select">                Select </option>    
  <option value="male">   Male   </option>
  <option value="female"> Female </option></select></td></tr> 
  <tr> <td> <input type="submit" value="Sign up" id="signup"/> </td> </tr>
 </table>
 </form>

and on signup page

$Gender  = $_POST["gender"];

i'm sure.. now, you will get the value..

You can't move a mouse but can lock it. Note: that you must call requestPointerLock in click event.

Small Example:

var canvas = document.getElementById('mycanvas');
canvas.requestPointerLock = canvas.requestPointerLock || canvas.mozRequestPointerLock || canvas.webkitRequestPointerLock;
canvas.requestPointerLock();

You may find an answer with this example : errorbar_demo_features.py

"""
Demo of errorbar function with different ways of specifying error bars.

Errors can be specified as a constant value (as shown in `errorbar_demo.py`),
or as demonstrated in this example, they can be specified by an N x 1 or 2 x N,
where N is the number of data points.

N x 1:
    Error varies for each point, but the error values are symmetric (i.e. the
    lower and upper values are equal).

2 x N:
    Error varies for each point, and the lower and upper limits (in that order)
    are different (asymmetric case)

In addition, this example demonstrates how to use log scale with errorbar.
"""
import numpy as np
import matplotlib.pyplot as plt

# example data
x = np.arange(0.1, 4, 0.5)
y = np.exp(-x)
# example error bar values that vary with x-position
error = 0.1 + 0.2 * x
# error bar values w/ different -/+ errors
lower_error = 0.4 * error
upper_error = error
asymmetric_error = [lower_error, upper_error]

fig, (ax0, ax1) = plt.subplots(nrows=2, sharex=True)
ax0.errorbar(x, y, yerr=error, fmt='-o')
ax0.set_title('variable, symmetric error')

ax1.errorbar(x, y, xerr=asymmetric_error, fmt='o')
ax1.set_title('variable, asymmetric error')
ax1.set_yscale('log')
plt.show()

Which plots this:

If you using angular-cli Keep the json file inside Assets folder (parallel to app dir) directory

return this.http.get('<json file path inside assets folder>.json'))
    .map((response: Response) => {
        console.log("mock data" + response.json());
        return response.json();
    }
    )
    .catch(this.handleError);
}

Note: here you only need to give path inside assets folder like assets/json/oldjson.json then you need to write path like /json/oldjson.json

If you using webpack then you need to follow above same structure inside public folder its similar like assets folder.

Renaming .bashrc to .profile (or soft-linking the latter to the former) should also do the trick. See here.

A new answer to reflect the most current practices: as of version 1.0.1, neither astype('str') nor astype(str) work.

As per the documentation, a Series can be converted to the string datatype in the following ways:

df['id'] = df['id'].astype("string")

df['id'] = pandas.Series(df['id'], dtype="string")

df['id'] = pandas.Series(df['id'], dtype=pandas.StringDtype)

Another variation:

git branch -r --sort=-committerdate --format='%(HEAD)%(color:yellow)%(refname:short)|%(color:bold green)%(committerdate:relative)|%(color:blue)%(subject)|%(color:magenta)%(authorname)%(color:reset)' --color=always | column -ts'|'

Worth noting that even though it's looking at changes in remote branches, it's worth syncing with origin before running the command (can use git fetch), as I found it can return out of date information if your local Git folder hasn't been updated in a while.

Also, this is a version that works in Windows cmd and PowerShell (didn't get output displayed in columns, would be interested to see if anyone gets this working):

git branch -r --sort=-committerdate --format="%(HEAD)%(color:yellow)%(refname:short)|%(color:bold green)%(committerdate:relative)|%(color:blue)%(subject)|%(color:magenta)%(authorname)%(color:reset)" --color=always

(For anyone still interested in the topic.)

Consider this (includes even usage of statements' return values in further statements within the "multiline" lambda, although it's ugly to the point of vomiting ;-)

>>> def foo(arg):
...     result = arg * 2;
...     print "foo(" + str(arg) + ") called: " + str(result);
...     return result;
...
>>> f = lambda a, b, state=[]: [
...     state.append(foo(a)),
...     state.append(foo(b)),
...     state.append(foo(state[0] + state[1])),
...     state[-1]
... ][-1];
>>> f(1, 2);
foo(1) called: 2
foo(2) called: 4
foo(6) called: 12
12

I see a number of answers using the Remove method and others using the Delete method.

Remove (according to the docs) will immediately remove the record from the (local) table, and on Update, will not remove a missing record.

Delete in comparison changes the RowState to Deleted, and will update the server table on Update. Likewise, calling the AcceptChanges method before the Update to the server table will reset all your RowState(s) to Unchanged and nothing will flow to the server. (Still nursing my thumb after hitting this a number of times).

We can also write jasmine's implementation of returning promise directly by spy.

spyOn(myOtherService, "makeRemoteCallReturningPromise").andReturn($q.when({}));

For Jasmine 2:

spyOn(myOtherService, "makeRemoteCallReturningPromise").and.returnValue($q.when({}));

IMHO I disagree with RickNotFred's statement:

Popping a dialog when an EditText gets focus seems like a non-standard interface.

Displaying a dialog to edit the date when the use presses the an EditText is very similar to the default, which is to display a keyboard or a numeric key pad. The fact that the date is displayed with the EditText signals to the user that the date may be changed. Displaying the date as a non-editable TextView signals to the user that the date may not be changed.

setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").

From the command line, you can type

python setup.py --help

...to get a list of commands. What you are looking to do is...

python setup.py install

for me the device selection bar (or whatever it's actually called) in logcat tab doesn't show, to resolve this I had to move logcat to some other position (left/right) and move it back

I have seen this once. Are the users requesting different amounts of data? I found that even if you can configure a binding for data payloads (i.e. maxReceivedMessageSize), the httpRuntime maxRequestLength trumps the WCF setting, so if IIS is trying to serve a request that exceeds that, it exhibits this behavior.

Think of it like this:

If maxReceivedMessageSize is 12MB in your WCF behavior, and maxRequestLength is 4MB (default), IIS wins.

For me, running the ad-hoc network on Windows 8.1, it was two things:

• I had to set a static IP on my Android (under Advanced Options under where you type the Wifi password)
• I had to use a password 8 characters long

Any IP will allow you to connect, but if you want internet access the static IP should match the subnet from the shared internet connection.

I'm not sure why I couldn't get a longer password to work, but it's worth a try. Maybe a more knowledgeable person could fill us in.

Other people have suggested using in.nextLine() to clear the buffer, which works for single-line input. As comments point out, however, sometimes System.in input can be multi-line.

You can instead create a new Scanner object where you want to clear the buffer if you are using System.in and not some other InputStream.

in = new Scanner(System.in);

If you do this, don't call in.close() first. Doing so will close System.in, and so you will get NoSuchElementExceptions on subsequent calls to in.nextInt(); System.in probably shouldn't be closed during your program.

(The above approach is specific to System.in. It might not be appropriate for other input streams.)

If you really need to close your Scanner object before creating a new one, this StackOverflow answer suggests creating an InputStream wrapper for System.in that has its own close() method that doesn't close the wrapped System.in stream. This is overkill for simple programs, though.

TL;DR: python -m pip install -U pip, then try again.

I was already using a venv (virtualenv) in PyCharm.

Creating it I clicked inherit global site packages checkbox, to allow packages installed via an installer to work. Now inside my venv there was no pip installed, so it would use the inherited global pip.

Here is how the error went:

(venv) D:\path\to\my\project> pip install certifi  # or any other package

Would fail with

PermissionError: [WinError 5] Access denied: 'c:\\program files\\python36\\Lib\\site-packages\\certifi'

Notice how that is the path of the system python, not the venv one. However we want it to execute in the right environment.

Here some more digging:

(venv) D:\path\to\my\project> which pip
/c/Program Files/Python36/Scripts/pip

(venv) D:\path\to\my\project> which python
/d/path/to/my/project/venv/Scripts/python

So python is using the correct path, but pip is not? Let's install pip here in the correct one as well:

(venv) D:\path\to\my\project> python -m pip install -U pip
... does stuff ...
Successfully installed pip

Now that's better. Running the original failing command again now works, as it is using the correct pip.

(venv) D:\path\to\my\project> pip install certifi  # or any other package
... install noise ...
Successfully installed certifi-2019.9.11 chardet-3.0.4 idna-2.8 requests-2.22.0 urllib3-1.25.7

use driver.findElement(By.partialLinkText("long")).click();

Two approaches:

1. Use Calendar and date(byAdding:to:wrappingComponents:). E.g., in Swift 3 and later:

   let calendar = Calendar.current
   let date = calendar.date(byAdding: .minute, value: 5, to: startDate)
   

2. Just use + operator (see +(_:_:)) to add a TimeInterval (i.e. a certain number of seconds). E.g. to add five minutes, you can:

   let date = startDate + 5 * 60
   

   (Note, the order is specific here: The date on the left side of the + and the seconds on the right side.)

   You can also use addingTimeInterval, if you’d prefer:

   let date = startDate.addingTimeInterval(5 * 60)
   

Bottom line, +/addingTimeInterval is easiest for simple scenarios, but if you ever want to add larger units (e.g., days, months, etc.), you would likely want to use the calendrical calculations because those adjust for daylight savings, whereas addingTimeInterval doesn’t.

For Swift 2 renditions, see the previous revision of this answer.

I cheated. Since the types I want to create (by name) are all in In a dll I control, I just put a static method in the dll in the assembly that takes a simple name, and calls type.GetType from that context and returns the result.

The original purpose was so that the type could be specified by name in configuration data. I've since change the code so that the user specified a format to process. The format handler classes implement a interface that determines if the type can parse the specified format. I then use reflection to find types that implement the interface, and find one that handles the format. So now the configuration specifies a format name, a not a specific type. The reflection code can look at adjacent dlls and load, them so I have a sort poor man's plug-in architecture.

print type(variable_name)

I also highly recommend the IPython interactive interpreter when dealing with questions like this. It lets you type variable_name? and will return a whole list of information about the object including the type and the doc string for the type.

e.g.

In [9]: var = 123

In [10]: var?
Type:       int
Base Class: <type 'int'>
String Form:    123
Namespace:  Interactive
Docstring:
    int(x[, base]) -> integer

Convert a string or number to an integer, if possible. A floating point argument will be truncated towards zero (this does not include a string representation of a floating point number!) When converting a string, use the optional base. It is an error to supply a base when converting a non-string. If the argument is outside the integer range a long object will be returned instead.

From Twitter Bootstrap documentation:

• medium grid (= 992px) = .col-md-*,
• large grid (= 1200px) = .col-lg-*.

I ended up using label names containing the values for the case expressions as suggested by AjV Jsy. Anyway, I use CALL instead of GOTO to jump into the correct case block and GOTO :EOF to jump back. The following sample code is a complete batch script illustrating the idea.

@ECHO OFF

SET /P COLOR="Choose a background color (type red, blue or black): "

2>NUL CALL :CASE_%COLOR% # jump to :CASE_red, :CASE_blue, etc.
IF ERRORLEVEL 1 CALL :DEFAULT_CASE # If label doesn't exist

ECHO Done.
EXIT /B

:CASE_red
  COLOR CF
  GOTO END_CASE
:CASE_blue
  COLOR 9F
  GOTO END_CASE
:CASE_black
  COLOR 0F
  GOTO END_CASE
:DEFAULT_CASE
  ECHO Unknown color "%COLOR%"
  GOTO END_CASE
:END_CASE
  VER > NUL # reset ERRORLEVEL
  GOTO :EOF # return from CALL

You need to use objcopy to separate the debug information:

objcopy --only-keep-debug "${tostripfile}" "${debugdir}/${debugfile}"
strip --strip-debug --strip-unneeded "${tostripfile}"
objcopy --add-gnu-debuglink="${debugdir}/${debugfile}" "${tostripfile}"

I use the bash script below to separate the debug information into files with a .debug extension in a .debug directory. This way I can tar the libraries and executables in one tar file and the .debug directories in another. If I want to add the debug info later on I simply extract the debug tar file and voila I have symbolic debug information.

This is the bash script:

#!/bin/bash

scriptdir=`dirname ${0}`
scriptdir=`(cd ${scriptdir}; pwd)`
scriptname=`basename ${0}`

set -e

function errorexit()
{
  errorcode=${1}
  shift
  echo $@
  exit ${errorcode}
}

function usage()
{
  echo "USAGE ${scriptname} <tostrip>"
}

tostripdir=`dirname "$1"`
tostripfile=`basename "$1"`


if [ -z ${tostripfile} ] ; then
  usage
  errorexit 0 "tostrip must be specified"
fi

cd "${tostripdir}"

debugdir=.debug
debugfile="${tostripfile}.debug"

if [ ! -d "${debugdir}" ] ; then
  echo "creating dir ${tostripdir}/${debugdir}"
  mkdir -p "${debugdir}"
fi
echo "stripping ${tostripfile}, putting debug info into ${debugfile}"
objcopy --only-keep-debug "${tostripfile}" "${debugdir}/${debugfile}"
strip --strip-debug --strip-unneeded "${tostripfile}"
objcopy --add-gnu-debuglink="${debugdir}/${debugfile}" "${tostripfile}"
chmod -x "${debugdir}/${debugfile}"

DELETE FROM konta WHERE taken <> '';

I had exactly the same problem. Just one more working modification of the solution given by Denis (the type must be specified):

SELECT ARRAY(
SELECT column_name::text
FROM information_schema.columns
WHERE table_name='aean'
)

I have implemented in Kotlin

edPassword.setOnTouchListener { _, event ->
            val DRAWABLE_RIGHT = 2
            val DRAWABLE_LEFT = 0
            val DRAWABLE_TOP = 1
            val DRAWABLE_BOTTOM = 3
            if (event.action == MotionEvent.ACTION_UP) {
                if (event.rawX >= (edPassword.right - edPassword.compoundDrawables[DRAWABLE_RIGHT].bounds.width())) {
                    edPassword.setText("")
                    true
                }
            }
            false
        }

Made some modification on Andrew's solution and update the code to Swift 3:

This code now use UITextView as self and able to inherit its original font, font size and text color

Note: toHexString() is extension from here

extension UITextView {
    func setAttributedStringFromHTML(_ htmlCode: String, completionBlock: @escaping (NSAttributedString?) ->()) {
        let inputText = "\(htmlCode)<style>body { font-family: '\((self.font?.fontName)!)'; font-size:\((self.font?.pointSize)!)px; color: \((self.textColor)!.toHexString()); }</style>"

        guard let data = inputText.data(using: String.Encoding.utf16) else {
            print("Unable to decode data from html string: \(self)")
            return completionBlock(nil)
        }

        DispatchQueue.main.async {
            if let attributedString = try? NSAttributedString(data: data, options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType], documentAttributes: nil) {
                self.attributedText = attributedString
                completionBlock(attributedString)
            } else {
                print("Unable to create attributed string from html string: \(self)")
                completionBlock(nil)
            }
        }
    }
}

Example usage:

mainTextView.setAttributedStringFromHTML("<i>Hello world!</i>") { _ in }

If you are using Go 1.5 above, you can try to use vendoring feature. It allows you to put your local package under vendor folder and import it with shorter path. In your case, you can put your common and routers folder inside vendor folder so it would be like

myapp/
--vendor/
----common/
----routers/
------middleware/
--main.go

and import it like this

import (
    "common"
    "routers"
    "routers/middleware"
)

This will work because Go will try to lookup your package starting at your project’s vendor directory (if it has at least one .go file) instead of $GOPATH/src.

FYI: You can do more with vendor, because this feature allows you to put "all your dependency’s code" for a package inside your own project's directory so it will be able to always get the same dependencies versions for all builds. It's like npm or pip in python, but you need to manually copy your dependencies to you project, or if you want to make it easy, try to look govendor by Daniel Theophanes

For more learning about this feature, try to look up here

I hope you or someone else find it helpfully

You could try something like this (copied from the jQuery Ajax examples)

var request = $.ajax({
  url: "script.php",
  type: "POST",
  data: {id : menuId},
  dataType: "html"
});

request.done(function(msg) {
  console.log( msg );
});

request.fail(function(jqXHR, textStatus) {
  console.log( "Request failed: " + textStatus );
});

The problem with your original code is that the error argument you pass into your on function isn't actually coming from anywhere. JQuery on doesn't return a second argument, and even if it did, it would relate to the click event not the Ajax call.

Stop with whatever you were doing ! :)

It is illegal to nest EL expressions: you should inline them. Using JSTL is perfectly valid in your situation. Correcting the mistake, you'll make the code working:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:c="http://java.sun.com/jstl/core">
    <c:if test="#{not empty user or user.userId eq 0}">
        <a href="Images/thumb_02.jpg" target="_blank" ></a>
        <img src="Images/thumb_02.jpg" />
    </c:if>
    <c:if test="#{empty user or user.userId eq 0}">
        <a href="/DisplayBlobExample?userId=#{user.userId}" target="_blank"></a>
        <img src="/DisplayBlobExample?userId=#{user.userId}" />
    </c:if>
</html>

Another solution is to specify all the conditions you want inside an EL of one element. Though it could be heavier and less readable, here it is:

<a href="#{not empty user or user.userId eq 0 ? '/Images/thumb_02.jpg' : '/DisplayBlobExample?userId='}#{not empty user or user.userId eq 0 ? '' : user.userId}" target="_blank"></a>
<img src="#{not empty user or user.userId eq 0 ? '/Images/thumb_02.jpg' : '/DisplayBlobExample?userId='}#{not empty user or user.userId eq 0 ? '' : user.userId}" target="_blank"></img>

The error may have occurred if your table doesn't have a primary key, in this case the table is "read only", and the db.SaveChanges () command will always error.

Thread.sleep() takes in the number of milliseconds to sleep, not seconds.

Sleeping for one millisecond is not noticeable. Try Thread.sleep(1000) to sleep for one second.

In C++, include a file in two ways:

The first one is #include which tells the preprocessor to look for the file in the predefined default location. This location is often an INCLUDE environment variable that denotes the path to include files.

And the second type is #include "filename" which tells the preprocessor to look for the file in the current directory first, then look for it in the predefined locations user have set up.

To do POST you'll need to have a form.

<form action="employee.action" method="post">
    <input type="submit" value="Employee1" />
</form>

There are some ways to post data with hyperlinks, but you'll need some javascript, and a form.

Some tricks: Make a link use POST instead of GET and How do you post data with a link

Edit: to load response on a frame you can target your form to your frame:

<form action="employee.action" method="post" target="myFrame">

There is a good article on this topic: PL/SQL: Sleep without using DBMS_LOCK that helped me out. I used Option 2 wrapped in a custom package. Proposed solutions are:

Option 1: APEX_UTIL.sleep

If APEX is installed you can use the procedure “PAUSE” from the publicly available package APEX_UTIL.

Example – “Wait 5 seconds”:

SET SERVEROUTPUT ON ;
BEGIN
    DBMS_OUTPUT.PUT_LINE('Start ' || to_char(SYSDATE, 'YYYY-MM-DD HH24:MI:SS'));
    APEX_UTIL.PAUSE(5);
    DBMS_OUTPUT.PUT_LINE('End   ' || to_char(SYSDATE, 'YYYY-MM-DD HH24:MI:SS'));
END;
/

Option 2: java.lang.Thread.sleep

An other option is the use of the method “sleep” from the Java class “Thread”, which you can easily use through providing a simple PL/SQL wrapper procedure:

Note: Please remember, that “Thread.sleep” uses milliseconds!

--- create ---
CREATE OR REPLACE PROCEDURE SLEEP (P_MILLI_SECONDS IN NUMBER) 
AS LANGUAGE JAVA NAME 'java.lang.Thread.sleep(long)';

--- use ---
SET SERVEROUTPUT ON ;
BEGIN
    DBMS_OUTPUT.PUT_LINE('Start ' || to_char(SYSDATE, 'YYYY-MM-DD HH24:MI:SS'));
    SLEEP(5 * 1000);
    DBMS_OUTPUT.PUT_LINE('End   ' || to_char(SYSDATE, 'YYYY-MM-DD HH24:MI:SS'));

How To Use the Spreadsheet Web Component with Visual Basic

Working with the Office Web Components

If you want give some default value to a parameter assign value in (). like (x =10). But important is first should compulsory argument then default value.

eg.

(y, x =10)

but

(x=10, y) is wrong

Taking up @ZF007's answer, this is not answering your question as a whole, but can be the solution for the same error. I post it here since I have not found a direct solution as an answer to this error message elsewhere on Stack Overflow.

The error appears when you check whether an array was empty or not.

• if np.array([1,2]): print(1) --> ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all().

• if np.array([1,2])[0]: print(1) --> no ValueError, but: if np.array([])[0]: print(1) --> IndexError: index 0 is out of bounds for axis 0 with size 0.

• if np.array([1]): print(1) --> no ValueError, but again will not help at an array with many elements.

• if np.array([]): print(1) --> DeprecationWarning: The truth value of an empty array is ambiguous. Returning False, but in future this will result in an error. Use 'array.size > 0' to check that an array is not empty.

Doing so:

• if np.array([]).size: print(1) solved the error.

The problem comes because of an interesting clash of new C++ features and what you're trying to do. First, let's take a look at the push_back signature:

void push_back(const T&)

It's expecting a reference to an object of type T. Under the old system of initialization, such a member exists. For example, the following code compiles just fine:

#include <vector>

class Foo {
public:
    static const int MEMBER;
};

const int Foo::MEMBER = 1; 

int main(){
    std::vector<int> v;
    v.push_back( Foo::MEMBER );       // undefined reference to `Foo::MEMBER'
    v.push_back( (int) Foo::MEMBER ); // OK  
    return 0;
}

This is because there is an actual object somewhere that has that value stored in it. If, however, you switch to the new method of specifying static const members, like you have above, Foo::MEMBER is no longer an object. It is a constant, somewhat akin to:

#define MEMBER 1

But without the headaches of a preprocessor macro (and with type safety). That means that the vector, which is expecting a reference, can't get one.

ViewContext.ModelState["id"].AttemptedValue

Listen , Make Following changes in your code if you want to show empty datetimepicker and get null when no date is selected by user, else save date.

1. Set datetimepicker FORMAT property to custom.
2. set CUSTOM FORMAT property to empty string " ".
3. set its TAG to 0 by default.
4. Register Event for datetimepicker VALUECHANGED.

Now real work starts

if user will interact with datetimepicker its VALUECHANGED event will be called and there set its TAG property to 1.

Final Step

Now when saving, check if its TAG is zero, then save NULL date else if TAG is 1 then pick and save Datetime picker value.

It Works like a charm.

Now if you want its value be changed back to empty by user interaction, then add checkbox and show text "Clear" with this checkbox. if user wants to clear date, simply again set its CUSTOM FORMAT property to empty string " ", and set its TAG back to 0. Thats it..

First parameter is stored in EAX register and result also.

Instead of using position: absolute, text-indent can be used to solve the "inside" problem:

li {
    list-style: inherit;
    margin: 0 0 4px 9px;
    text-indent: -9px;
}
li:before {
    content: "· ";

To see if two maps have the same values, you can do the following:

• Get their Collection<V> values() views
• Wrap into List<V>
• Collections.sort those lists
• Test if the two lists are equals

Something like this works (though its type bounds can be improved on):

static <V extends Comparable<V>>
boolean valuesEquals(Map<?,V> map1, Map<?,V> map2) {
    List<V> values1 = new ArrayList<V>(map1.values());
    List<V> values2 = new ArrayList<V>(map2.values());
    Collections.sort(values1);
    Collections.sort(values2);
    return values1.equals(values2);
}

Test harness:

Map<String, String> map1 = new HashMap<String,String>();
map1.put("A", "B");
map1.put("C", "D");

Map<String, String> map2 = new HashMap<String,String>();
map2.put("A", "D");
map2.put("C", "B");

System.out.println(valuesEquals(map1, map2)); // prints "true"

This is O(N log N) due to Collections.sort.

See also:

• Collection<V> values()

To test if the keys are equals is easier, because they're Set<K>:

map1.keySet().equals(map2.keySet())

• Set<K> keySet()

I use the utility below to cleanup after my integration test run.

It uses the latest AdminZkClient api. The older api has been deprecated.

import javax.inject.Inject
import kafka.zk.{AdminZkClient, KafkaZkClient}
import org.apache.kafka.common.utils.Time

class ZookeeperUtils @Inject() (config: AppConfig) {

  val testTopic = "users_1"

  val zkHost = config.KafkaConfig.zkHost
  val sessionTimeoutMs = 10 * 1000
  val connectionTimeoutMs = 60 * 1000
  val isSecure = false
  val maxInFlightRequests = 10
  val time: Time = Time.SYSTEM

  def cleanupTopic(config: AppConfig) = {

    val zkClient = KafkaZkClient.apply(zkHost, isSecure, sessionTimeoutMs, connectionTimeoutMs, maxInFlightRequests, time)
    val zkUtils = new AdminZkClient(zkClient)

    val pp = new Properties()
    pp.setProperty("delete.retention.ms", "10")
    pp.setProperty("file.delete.delay.ms", "1000")
    zkUtils.changeTopicConfig(testTopic , pp)
    //    zkUtils.deleteTopic(testTopic)

    println("Waiting for topic to be purged. Then reset to retain records for the run")
    Thread.sleep(60000L)

    val resetProps = new Properties()
    resetProps.setProperty("delete.retention.ms", "3000000")
    resetProps.setProperty("file.delete.delay.ms", "4000000")
    zkUtils.changeTopicConfig(testTopic , resetProps)

  }


}

There is an option delete topic. But, it marks the topic for deletion. Zookeeper later deletes the topic. Since this can be unpredictably long, I prefer the retention.ms approach

new Date().toString("yyyyMMddHHmmss").
      replace(/T/, ' ').  
      replace(/\..+/, '') 

with .toString(), This becomes in format

replace(/T/, ' '). //replace T to ' ' 2017-01-15T...

replace(/..+/, '') //for ...13:50:16.1271

example, see var date and hour:

var date="2017-01-15T13:50:16.1271".toString("yyyyMMddHHmmss")._x000D_
                    replace(/T/, ' ').      _x000D_
                    replace(/\..+/, '');_x000D_
    _x000D_
                    var auxCopia=date.split(" ");_x000D_
                    date=auxCopia[0];_x000D_
                    var hour=auxCopia[1];_x000D_
_x000D_
console.log(date);_x000D_
console.log(hour);

Please find the code below for Vlookup:

Function vlookupVBA(lookupValue, rangeString, colOffset)
vlookupVBA = "#N/A"
On Error Resume Next
Dim table_lookup As range
Set table_lookup = range(rangeString)
vlookupVBA = Application.WorksheetFunction.vlookup(lookupValue, table_lookup, colOffset, False)
End Function

$foo = Bar::getBeers(); $foo = $foo->toArray();

Given that the only logical difference between the handlers is the value of the button clicked, you can use the this keyword to refer to the element which raised the event and get the val() from that. Try this:

$("button").click(function(e) {
    e.preventDefault();
    $.ajax({
        type: "POST",
        url: "/pages/test/",
        data: { 
            id: $(this).val(), // < note use of 'this' here
            access_token: $("#access_token").val() 
        },
        success: function(result) {
            alert('ok');
        },
        error: function(result) {
            alert('error');
        }
    });
});

Thought I would chip in here with when I have found ON to be more useful than USING. It is when OUTER joins are introduced into queries.

ON benefits from allowing the results set of the table that a query is OUTER joining onto to be restricted while maintaining the OUTER join. Attempting to restrict the results set through specifying a WHERE clause will, effectively, change the OUTER join into an INNER join.

Granted this may be a relative corner case. Worth putting out there though.....

For example:

CREATE TABLE country (
   countryId int(10) unsigned NOT NULL PRIMARY KEY AUTO_INCREMENT,
   country varchar(50) not null,
  UNIQUE KEY countryUIdx1 (country)
) ENGINE=InnoDB;

insert into country(country) values ("France");
insert into country(country) values ("China");
insert into country(country) values ("USA");
insert into country(country) values ("Italy");
insert into country(country) values ("UK");
insert into country(country) values ("Monaco");


CREATE TABLE city (
  cityId int(10) unsigned NOT NULL PRIMARY KEY AUTO_INCREMENT,
  countryId int(10) unsigned not null,
  city varchar(50) not null,
  hasAirport boolean not null default true,
  UNIQUE KEY cityUIdx1 (countryId,city),
  CONSTRAINT city_country_fk1 FOREIGN KEY (countryId) REFERENCES country (countryId)
) ENGINE=InnoDB;


insert into city (countryId,city,hasAirport) values (1,"Paris",true);
insert into city (countryId,city,hasAirport) values (2,"Bejing",true);
insert into city (countryId,city,hasAirport) values (3,"New York",true);
insert into city (countryId,city,hasAirport) values (4,"Napoli",true);
insert into city (countryId,city,hasAirport) values (5,"Manchester",true);
insert into city (countryId,city,hasAirport) values (5,"Birmingham",false);
insert into city (countryId,city,hasAirport) values (3,"Cincinatti",false);
insert into city (countryId,city,hasAirport) values (6,"Monaco",false);

-- Gah. Left outer join is now effectively an inner join 
-- because of the where predicate
select *
from country left join city using (countryId)
where hasAirport
; 

-- Hooray! I can see Monaco again thanks to 
-- moving my predicate into the ON
select *
from country co left join city ci on (co.countryId=ci.countryId and ci.hasAirport)
; 

To modify DSM's answer a bit, get_loc has some weird properties depending on the type of index in the current version of Pandas (1.1.5) so depending on your Index type you might get back an index, a mask, or a slice. This is somewhat frustrating for me because I don't want to modify the entire columns just to extract one variable's index. Much simpler is to avoid the function altogether:

list(df.columns).index('pear')

Very straightforward and probably fairly quick.

Try 'build-essential' instead.

if
  ...
  # several checks
  ...
elif not (1024<=var<=65535 or var == 80 or var == 443)
  # fail
else
  ...

The two approaches are not interchangeable. You should initialize state in the constructor when using ES6 classes, and define the getInitialState method when using React.createClass.

See the official React doc on the subject of ES6 classes.

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = { /* initial state */ };
  }
}

is equivalent to

var MyComponent = React.createClass({
  getInitialState() {
    return { /* initial state */ };
  },
});

I was struggling to get this done because I couldn't get image size and text width on my view's constructor. Two minor changes on Jesse's answer worked for me:

CGFloat spacing = 3;
self.titleEdgeInsets = UIEdgeInsetsMake(0.0, - image.size.width, - (image.size.height + spacing), 0.0);
CGSize titleSize = [name sizeWithAttributes:@{NSFontAttributeName:self.titleLabel.font}];
self.imageEdgeInsets = UIEdgeInsetsMake(- (titleSize.height + spacing), 0.0, 0.0, - titleSize.width);

The change are:

• Using [NSString sizeWithAttributes] to get text width;
• Get image size directly on the UIImage instead of UIImageView

I came across this question while Googling for "git remove folder from tracking". The OP's question lead me to the answer. I am summarizing it here for future generations.

Question

How do I remove a folder from my git repository without deleting it from my local machine (i.e., development environment)?

Answer

Step 1. Add the folder path to your repo's root .gitignore file.

path_to_your_folder/

Step 2. Remove the folder from your local git tracking, but keep it on your disk.

git rm -r --cached path_to_your_folder/

Step 3. Push your changes to your git repo.

The folder will be considered "deleted" from Git's point of view (i.e. they are in past history, but not in the latest commit, and people pulling from this repo will get the files removed from their trees), but stay on your working directory because you've used --cached.

In Android simply edit your styles.xml file under Resources\values adding this:

<resources>
  <style name="MyTheme" parent="android:style/Theme.Material.Light.DarkActionBar">
   <item name="android:colorPressedHighlight">@color/ListViewSelected</item>
   <item name="android:colorLongPressedHighlight">@color/ListViewHighlighted</item>
   <item name="android:colorFocusedHighlight">@color/ListViewSelected</item>
   <item name="android:colorActivatedHighlight">@color/ListViewSelected</item>
   <item name="android:activatedBackgroundIndicator">@color/ListViewSelected</item>
  </style>
<color name="ListViewSelected">#96BCE3</color>
<color name="ListViewHighlighted">#E39696</color>
</resources>

I do understand, that your question was about files stored in MEDIA_ROOT, but sometimes it can be possible to store content in static, when you are not planning to create content of that type anymore.
May be this is a rare case, but anyway - if you have a huge amount of "pictures of the day" for your site - and all these files are on your hard drive?

In that case I see no contra to store such a content in STATIC.
And all becomes really simple:

static

To link to static files that are saved in STATIC_ROOT Django ships with a static template tag. You can use this regardless if you're using RequestContext or not.

{% load static %} <img src="{% static "images/hi.jpg" %}" alt="Hi!" />

copied from Official django 1.4 documentation / Built-in template tags and filters

Component is the template(view) + a class (Typescript code) containing some logic for the view + metadata(to tell angular about from where to get data it needs to display the template).

Modules basically group the related components, services together so that you can have chunks of functionality which can then run independently. For example, an app can have modules for features, for grouping components for a particular feature of your app, such as a dashboard, which you can simply grab and use inside another application.

How floats work

When floating elements exist on the page, non-floating elements wrap around the floating elements, similar to how text goes around a picture in a newspaper. From a document perspective (the original purpose of HTML), this is how floats work.

float vs display:inline

Before the invention of display:inline-block, websites use float to set elements beside each other. float is preferred over display:inline since with the latter, you can't set the element's dimensions (width and height) as well as vertical paddings (top and bottom) - which floated elements can do since they're treated as block elements.

Float problems

The main problem is that we're using float against its intended purpose.

Another is that while float allows side-by-side block-level elements, floats do not impart shape to its container. It's like position:absolute, where the element is "taken out of the layout". For instance, when an empty container contains a floating 100px x 100px <div>, the <div> will not impart 100px in height to the container.

Unlike position:absolute, it affects the content that surrounds it. Content after the floated element will "wrap" around the element. It starts by rendering beside it and then below it, like how newspaper text would flow around an image.

Clearfix to the rescue

What clearfix does is to force content after the floats or the container containing the floats to render below it. There are a lot of versions for clear-fix, but it got its name from the version that's commonly being used - the one that uses the CSS property clear.

Examples

Here are several ways to do clearfix , depending on the browser and use case. One only needs to know how to use the clear property in CSS and how floats render in each browser in order to achieve a perfect cross-browser clear-fix.

What you have

Your provided style is a form of clearfix with backwards compatibility. I found an article about this clearfix. It turns out, it's an OLD clearfix - still catering the old browsers. There is a newer, cleaner version of it in the article also. Here's the breakdown:

• The first clearfix you have appends an invisible pseudo-element, which is styled clear:both, between the target element and the next element. This forces the pseudo-element to render below the target, and the next element below the pseudo-element.

• The second one appends the style display:inline-block which is not supported by earlier browsers. inline-block is like inline but gives you some properties that block elements, like width, height as well as vertical padding. This was targeted for IE-MAC.

• This was the reapplication of display:block due to IE-MAC rule above. This rule was "hidden" from IE-MAC.

All in all, these 3 rules keep the .clearfix working cross-browser, with old browsers in mind.

@jim mcnamara: try using parentheses for around NF, i. e. $(NF-1) and $(NF) instead of $NF-1 and $NF (works on Mac OS X 10.6.8 for FreeBSD awkand gawk).

echo '
1 2
2 3
one
one two three
' | gawk '{if (NF >= 2) print $(NF-1), $(NF);}'

# output:
# 1 2
# 2 3
# two three

I think you could get away with using relative positioning and then set the top/left positioning of the second DIV until you have it in the position desired.

Enumerable.SequenceEqual(FirstList.OrderBy(fElement => fElement), 
                         SecondList.OrderBy(sElement => sElement))

Another version @Steffomio

Instead of adding each item individually we can add items by chunks.

// chunks function from here: 
// http://stackoverflow.com/questions/8495687/split-array-into-chunks#11764168
var chunks = chunk(folders, 100);

//immediate display of our first set of items
$scope.items = chunks[0];

var delay = 100;
angular.forEach(chunks, function(value, index) {
    delay += 100;

    // skip the first chuck
    if( index > 0 ) {
        $timeout(function() {
            Array.prototype.push.apply($scope.items,value);
        }, delay);
    }       
});

@str = "<span class=\"classname\">hello</span>" If in my view I do

<%raw @str %> The HTML source code is <span class=\"classname\">hello</span> where what I really want is <span class="classname">hello</span> (without the backslashes that were escaping the double >quotes). What's the best way to "unescape" those double quotes?

Solution: use double quotes inside of single quotes (or single inside of double) to avoid escaping with a backslash.

@str = '<span class="classname">hello</span>'
<%raw @str %>

Try this: service crond restart, Hence it's crond not cron.

Yes. Here's the way using pipe( | ) separator,

try
{
    .......
}    
catch
{
    catch(IllegalArgumentException | SecurityException | IllegalAccessException | NoSuchFieldException e)
}

It should be just DateTime.ToString( "MMMM" )

You don't need all the extra Ms.

Just another solution, hope some one may like it :

Using: [False, True][Expression]

>>> map(lambda x: [x*100, x][x % 2 != 0], range(1,10))
[1, 200, 3, 400, 5, 600, 7, 800, 9]
>>>

Below code for best examples for nested loops, while using two for loops please remember the output of the first loop is input for the second loop. Loop termination also important while using the nested loops

for x in range(1, 10, 1):
     for y in range(1,x):
             print y,
        print
OutPut :
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7
1 2 3 4 5 6 7 8

For a bit of a different approach you could use something like this on the list:

position: absolute;
top: 18px;
bottom: 0px;
width: 100%;

This works as long as the parent container has position: relative;

Dissenting voice here: after 5 years of rspec I don't like let very much.

1. Lazy evaluation often makes test setup confusing

It becomes difficult to reason about setup when some things that have been declared in setup are not actually affecting state, while others are.

Eventually, out of frustration someone just changes let to let! (same thing without lazy evaluation) in order to get their spec working. If this works out for them, a new habit is born: when a new spec is added to an older suite and it doesn't work, the first thing the writer tries is to add bangs to random let calls.

Pretty soon all the performance benefits are gone.

2. Special syntax is unusual to non-rspec users

I would rather teach Ruby to my team than the tricks of rspec. Instance variables or method calls are useful everywhere in this project and others, let syntax will only be useful in rspec.

3. The "benefits" allow us to easily ignore good design changes

let() is good for expensive dependencies that we don't want to create over and over. It also pairs well with subject, allowing you to dry up repeated calls to multi-argument methods

Expensive dependencies repeated in many times, and methods with big signatures are both points where we could make the code better:

• maybe I can introduce a new abstraction that isolates a dependency from the rest of my code (which would mean fewer tests need it)
• maybe the code under test is doing too much
• maybe I need to inject smarter objects instead of a long list of primitives
• maybe I have a violation of tell-don't-ask
• maybe the expensive code can be made faster (rarer - beware of premature optimisation here)

In all these cases, I can address the symptom of difficult tests with a soothing balm of rspec magic, or I can try address the cause. I feel like I spent way too much of the last few years on the former and now I want some better code.

To answer the original question: I would prefer not to, but I do still use let. I mostly use it to fit in with the style of the rest of the team (it seems like most Rails programmers in the world are now deep into their rspec magic so that is very often). Sometimes I use it when I'm adding a test to some code that I don't have control of, or don't have time to refactor to a better abstraction: i.e. when the only option is the painkiller.

All the download process is too long, just navigate to your project preview and select project view, right click on app folder, then click on new, then create a new image asset. Kindly choose the file path and click next and finish.

important: Reinstall your app.

From a module:

UserFormName.UserForm_Initialize

Just make sure that in your userform, you update the sub like so:

Public Sub UserForm_Initialize() so it can be called from outside the form.

Alternately, if the Userform hasn't been loaded:

UserFormName.Show will end up calling UserForm_Initialize because it loads the form.

I installed DNSpython 2.0.0 from the github source, but running 'pip list' showed the old version of dnspython 1.2.0

It only worked after I ran 'pip uninstall dnspython' which removed the old version leaving just 2.0.0 and then 'import dns' ran smoothly

LinearLayout : A layout that organizes its children into a single horizontal or vertical row. It creates a scrollbar if the length of the window exceeds the length of the screen.It means you can align views one by one (vertically/ horizontally).

RelativeLayout : This enables you to specify the location of child objects relative to each other (child A to the left of child B) or to the parent (aligned to the top of the parent). It is based on relation of views from its parents and other views.

WebView : to load html, static or dynamic pages.

For more information refer this link:http://developer.android.com/guide/topics/ui/layout-objects.html

I've had similar requirements as described in the question and it took a while to figure things out based on existing answers, so I would like to share my final solution.

Requirements

The state of my view (component, technically) can be changed by the user (filter settings, sorting options, etc.) When state changes happen, i.e. the user changes the sorting direction, I want to:

• Reflect the state changes in the URL
• Handle state changes, i.e. make an API call to receive a new result set

additionally, I would like to:

• Specify if the URL changes are considered in the browser history (back/forward) based on circumstances
• use complex objects as state params to provide greater flexibility in handling of state changes (optional, but makes life easier for example when some state changes trigger backend/API calls while others are handled by the frontend internally)

Solution: Change state without reloading component

A state change does not cause a component reload when using route parameters or query parameters. The component instance stays alive. I see no good reason to mess with the router state by using Location.go() or location.replaceState().

var state = { q: 'foo', sort: 'bar' }; 
var url = this.router.createUrlTree([], { relativeTo: this.activatedRoute, queryParams: state }).toString();
this.router.navigateByUrl(url);

The state object will be transformed to URL query params by Angular's Router:

https://localhost/some/route?q=foo&sort=bar

Solution: Handling state changes to make API calls

The state changes triggered above can be handled by subscribing to ActivatedRoute.queryParams:

export class MyComponent implements OnInit {

   constructor(private activatedRoute: ActivatedRoute) { }

   ngOnInit()
   {
      this.activatedRoute.queryParams.subscribe((params) => {
         // params is the state object passed to the router on navigation 
         // Make API calls here
      });
   }

}

The state object of the above axample will be passed as the params argument of the queryParams observable. In the handler API calls can be made if necessary.

But: I would prefer handling the state changes directly in my component and avoid the detour over ActivatedRoute.queryParams. IMO, navigating the router, letting Angular do routing magic and handle the queryParams change to do something, completely obfuscates whats happening in my component with regards to maintenability and readability of my code. What I do instead:

Compare the state passed in to queryParams observable with the current state in my component, do nothing, if it hasn't changed there and handle state changes directly instead:

export class MyComponent implements OnInit {

   private _currentState;

   constructor(private activatedRoute: ActivatedRoute) { }

   ngOnInit()
   {
      this.activatedRoute.queryParams.subscribe((params) => {
         // Following comparison assumes, that property order doesn't change
         if (JSON.stringify(this._currentState) == JSON.stringify(params)) return;
         // The followig code will be executed only when the state changes externally, i.e. through navigating to a URL with params by the user
         this._currentState = params;
         this.makeApiCalls();
      });
   }

   updateView()
   {          
      this.makeApiCalls();
      this.updateUri();
   }    

   updateUri()
   {
      var url = this.router.createUrlTree([], { relativeTo: this.activatedRoute, queryParams: this._currentState }).toString();
this.router.navigateByUrl(url);
   }
}

Solution: Specify browser history behavior

var createHistoryEntry = true // or false
var url = ... // see above
this.router.navigateByUrl(url, { replaceUrl : !createHistoryEntry});

Solution: Complex objects as state

This is beyond the original question but adresses common scenarios and might thus be useful: The state object above is limited to flat objects (an object with only simple string/bool/int/... properties but no nested objects). I found this limiting, because I need to distinguish between properties that need to be handled with a backend call and others, that are only used by the component internally. I wanted a state object like:

var state = { filter: { something: '', foo: 'bar' }, viewSettings: { ... } };

To use this state as queryParams object for the router, it needs to be flattened. I simply JSON.stringify all first level properties of the object:

private convertToParamsData(data) {
    var params = {};

    for (var prop in data) {
      if (Object.prototype.hasOwnProperty.call(data, prop)) {
        var value = data[prop];
        if (value == null || value == undefined) continue;
        params[prop] = JSON.stringify(value, (k, v) => {
          if (v !== null) return v
        });
      }
    }
    return params;
 }

and back, when handling the queryParams returned passed in by the router:

private convertFromParamsData(params) {
    var data = {};

    for (var prop in params) {
      if (Object.prototype.hasOwnProperty.call(params, prop)) {
        data[prop] = JSON.parse(params[prop]);
      }
    }
    return data;
}

Finally: A ready-to-use Angular service

And finally, all of this isolated in one simple service:

import { Injectable } from '@angular/core';
import { ActivatedRoute, Router } from '@angular/router';
import { Observable } from 'rxjs';
import { Location } from '@angular/common';
import { map, filter, tap } from 'rxjs/operators';

@Injectable()
export class QueryParamsService {

  private currentParams: any;

  externalStateChange: Observable<any>;

  constructor(private activatedRoute: ActivatedRoute, private router: Router, private location: Location) {

    this.externalStateChange = this.activatedRoute.queryParams
      .pipe(map((flatParams) => {
        var params = this.convertFromParamsData(flatParams);
        return params
      }))
      .pipe(filter((params) => {
        return !this.equalsCurrentParams(params);
      }))
      .pipe(tap((params) => {
        this.currentParams = params;
      }));
  }

  setState(data: any, createHistoryEntry = false) {
    var flat = this.convertToParamsData(data);
    const url = this.router.createUrlTree([], { relativeTo: this.activatedRoute, queryParams: flat }).toString();
    this.currentParams = data;
    this.router.navigateByUrl(url, { replaceUrl: !createHistoryEntry });
  }

  private equalsCurrentParams(data) {
    var isEqual = JSON.stringify(data) == JSON.stringify(this.currentParams);
    return isEqual;
  }

  private convertToParamsData(data) {
    var params = {};

    for (var prop in data) {
      if (Object.prototype.hasOwnProperty.call(data, prop)) {
        var value = data[prop];
        if (value == null || value == undefined) continue;
        params[prop] = JSON.stringify(value, (k, v) => {
          if (v !== null) return v
        });
      }
    }
    return params;
  }

  private convertFromParamsData(params) {
    var data = {};

    for (var prop in params) {
      if (Object.prototype.hasOwnProperty.call(params, prop)) {
        data[prop] = JSON.parse(params[prop]);
      }
    }
    return data;
  }
}

which can be used like:

@Component({
  selector: "app-search",
  templateUrl: "./search.component.html",
  styleUrls: ["./search.component.scss"],
  providers: [QueryParamsService]
})
export class ProjectSearchComponent implements OnInit {

    filter : any;

    viewSettings : any;

    constructor(private queryParamsService: QueryParamsService) { }

    ngOnInit(): void {

        this.queryParamsService.externalStateChange
          .pipe(debounce(() => interval(500))) // Debounce optional
          .subscribe(params => {
           // Set state from params, i.e.
           if (params.filter) this.filter = params.filter;
           if (params.viewSettings) this.viewSettings = params.viewSettings;

           // You might want to init this.filter, ... with default values here
           // If you want to write default values to URL, you can call setState here
            this.queryParamsService.setState(params, false); // false = no history entry

            this.initializeView(); //i.e. make API calls        
         });
     }

     updateView() {

       var data = {
         filter: this.filter,
         viewSettings: this.viewSettings
       };

       this.queryParamsService.setState(data, true);

       // Do whatever to update your view
     }

  // ...

}

Don't forget the providers: [QueryParamsService] statement on component level to create a new service instance for the component. Don't register the service globally on app module.

On Java 9 or later, Map.entry can be used, so long as you know that neither the key nor value will be null. If either value could legitimately be null, AbstractMap.SimpleEntry (as suggested in another answer) or AbstractMap.SimpleImmutableEntry would be the way to go.

private Map<String, AttributeType> mapConfig(Map<String, String> input, String prefix) {
   int subLength = prefix.length();
   return input.entrySet().stream().map(e -> 
      Map.entry(e.getKey().substring(subLength), AttributeType.GetByName(e.getValue())));
   }).collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));
}

Rather than trying to pull the raw traffic data, you can try a different approach. The Google Directions API allows you to query the api with a particular route and returns a JSON string or XML element as a result. This result includes the element - ' duration_in_traffic ' This indicates the total duration of the particular leg of the journey, taking into account current traffic conditions. (for information on 'leg' and other elements of the JSON string returned by the Directions API refer link below)

https://developers.google.com/maps/documentation/directions/#JSON I haven't tried this myself but just something I came across in the documentation.

This is a general rambling on Parallelism in SQL Server, it might not answer your question directly.

From Books Online, on MAXDOP:

Sets the maximum number of processors the query processor can use to execute a single index statement. Fewer processors may be used depending on the current system workload.

See Rickie Lee's blog on parallelism and CXPACKET wait type. It's quite interesting.

Generally, in an OLTP database, my opinion is that if a query is so costly it needs to be executed on several processors, the query needs to be re-written into something more efficient.

Why you get better results adding MAXDOP(1)? Hard to tell without the actual execution plans, but it might be so simple as that the execution plan is totally different that without the OPTION, for instance using a different index (or more likely) JOINing differently, using MERGE or HASH joins.

I use SDL_GetTicks from the SDL library.

You can use the minus operator or Math.abs. These work for all negative integers EXCEPT for Integer.MIN_VALUE! If you do 0 - MIN_VALUE the answer is still MIN_VALUE.

Regarding the difference between an object and an instance, I do not think there is any consensus.

It looks to me like people change it pretty much interchangeably, in papers, blog posts, books or conversations.

As for me, the way I see it is, an object is a generic and alive entity in the memory, specified by the language it is used in. Just like the Object class in Java. We do not much care its type, or anything else associated with it, whether it is managed by a container or not.

An instance is an object but associated with a type, as in this method accepts Foo instances, or you can not put Animal instances in an instance of a List of Vehicles.

objects for example have locks associated with them, not instances, whereas instances have methods. objects are garbage collected, not instances.

But as I said, this is only how I see it, and I do not think there is any organisation we can refer to for a standard definition between them and everyone will pretty much have their slightly different understanding / definitions (of course within limits).

You had two problems:

1) The order in which you included the HTML. Try changing the dropdown from "onLoad" to "no wrap - head" in the JavaScript settings of your fiddle.

2) Your function prints the values. What you're actually after is the text

x.options[i].text; instead of x.options[i].value;

pack_forget and grid_forget will only remove widgets from view, it doesn't destroy them. If you don't plan on re-using the widgets, your only real choice is to destroy them with the destroy method.

To do that you have two choices: destroy each one individually, or destroy the frame which will cause all of its children to be destroyed. The latter is generally the easiest and most effective.

Since you claim you don't want to destroy the container frame, create a secondary frame. Have this secondary frame be the container for all the widgets you want to delete, and then put this one frame inside the parent you do not want to destroy. Then, it's just a matter of destroying this one frame and all of the interior widgets will be destroyed along with it.

From the Java API specification:

FileWriter

Convenience class for writing character files. The constructors of this class assume that the default character encoding and the default byte-buffer size are acceptable.

BufferedWriter

Write text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings.

You can use the Contains() extension method:

list.Where(r => listofIds.Contains(r.Id))

Here's what I was able to get working on version 5.4.2 (from the nuget install) to return a pdf response from an asp.net mvc controller. It could be modfied to use a FileStream instead of MemoryStream for the output if that's what is needed.

I post it here because it is a complete example of current iTextSharp usage for the html -> pdf conversion (disregarding images, I haven't looked at that since my usage doesn't require it)

It uses iTextSharp's XmlWorkerHelper, so the incoming hmtl must be valid XHTML, so you may need to do some fixup depending on your input.

using iTextSharp.text.pdf;
using iTextSharp.tool.xml;
using System.IO;
using System.Web.Mvc;

namespace Sample.Web.Controllers
{
    public class PdfConverterController : Controller
    {
        [ValidateInput(false)]
        [HttpPost]
        public ActionResult HtmlToPdf(string html)
        {           

            html = @"<?xml version=""1.0"" encoding=""UTF-8""?>
                 <!DOCTYPE html

                  <body>
                    " + html + "</body></html>";

            var bytes = System.Text.Encoding.UTF8.GetBytes(html);

            using (var input = new MemoryStream(bytes))
            {
                var output = new MemoryStream(); // this MemoryStream is closed by FileStreamResult

                var document = new iTextSharp.text.Document(iTextSharp.text.PageSize.LETTER, 50, 50, 50, 50);
                var writer = PdfWriter.GetInstance(document, output);
                writer.CloseStream = false;
                document.Open();

                var xmlWorker = XMLWorkerHelper.GetInstance();
                xmlWorker.ParseXHtml(writer, document, input, null);
                document.Close();
                output.Position = 0;

                return new FileStreamResult(output, "application/pdf");
            }
        }

Thanks to everyone's contributions to this question, I've come up with the following script. Change the values for $SvcName and $SvrName to suit your needs. This script will start the remote service if it is stopped, or stop it if it is started. And it uses the cool .WaitForStatus method to wait while the service responds.

#Change this values to suit your needs:
$SvcName = 'Spooler'
$SvrName = 'remotePC'

#Initialize variables:
[string]$WaitForIt = ""
[string]$Verb = ""
[string]$Result = "FAILED"
$svc = (get-service -computername $SvrName -name $SvcName)
Write-host "$SvcName on $SvrName is $($svc.status)"
Switch ($svc.status) {
    'Stopped' {
        Write-host "Starting $SvcName..."
        $Verb = "start"
        $WaitForIt = 'Running'
        $svc.Start()}
    'Running' {
        Write-host "Stopping $SvcName..."
        $Verb = "stop"
        $WaitForIt = 'Stopped'
        $svc.Stop()}
    Default {
        Write-host "$SvcName is $($svc.status).  Taking no action."}
}
if ($WaitForIt -ne "") {
    Try {  # For some reason, we cannot use -ErrorAction after the next statement:
        $svc.WaitForStatus($WaitForIt,'00:02:00')
    } Catch {
        Write-host "After waiting for 2 minutes, $SvcName failed to $Verb."
    }
    $svc = (get-service -computername $SvrName -name $SvcName)
    if ($svc.status -eq $WaitForIt) {$Result = 'SUCCESS'}
    Write-host "$Result`: $SvcName on $SvrName is $($svc.status)"
}

Of course, the account you run this under will need the proper privileges to access the remote computer and start and stop services. And when executing this against older remote machines, you might first have to install WinRM 3.0 on the older machine.

It's a buzzword that refers to things like the normal Web architecture with e.g., Javascript - ASP.Net - Middleware - Database layer. Each of these things is a "tier".

Here is something I used to drop files and/or folders full of files. In my case I was filtering for *.dwg files only and chose to include all subfolders.

fileList is an IEnumerable or similar In my case was bound to a WPF control...

var fileList = (IList)FileList.ItemsSource;

See https://stackoverflow.com/a/19954958/492 for details of that trick.

The drop Handler ...

  private void FileList_OnDrop(object sender, DragEventArgs e)
  {
    var dropped = ((string[])e.Data.GetData(DataFormats.FileDrop));
    var files = dropped.ToList();

    if (!files.Any())
      return;

    foreach (string drop in dropped)
      if (Directory.Exists(drop))
        files.AddRange(Directory.GetFiles(drop, "*.dwg", SearchOption.AllDirectories));

    foreach (string file in files)
    {
      if (!fileList.Contains(file) && file.ToLower().EndsWith(".dwg"))
        fileList.Add(file);
    }
  }

Since AngularJS does not have directive DOM manipulations as jQuery does, a proper way to modify attributes of one element will be using directive. Through link function of a directive, you have access to both element and its attributes.

Wrapping you whole input inside one directive, you can still introduce ng-model's methods through controller property.

This method will help to decouple the logic of ngmodel with placeholder from controller. If there is no logic between them, you can definitely go as Wagner Francisco said.

I using "+" (plus) to insert div to html :

document.getElementById('idParent').innerHTML += '<div id="idChild"> content html </div>';

Hope this help.

I had some problems with FragmentStatePagerAdapter. After removing an item:

• there was another item used for a position (an item which did not belong to the position but to a position next to it)
• or some fragment was not loaded (there was only blank background visible on that page)

After lots of experiments, I came up with the following solution.

public class SomeAdapter extends FragmentStatePagerAdapter {

    private List<Item> items = new ArrayList<Item>();

    private boolean removing;

    @Override
    public Fragment getItem(int position) {
        ItemFragment fragment = new ItemFragment();
        Bundle args = new Bundle();
        // use items.get(position) to configure fragment
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public int getCount() {
        return items.size();
    }

    @Override
    public int getItemPosition(Object object) {
        if (removing) {
            return PagerAdapter.POSITION_NONE;
        }

        Item item = getItemOfFragment(object);

        int index = items.indexOf(item);
        if (index == -1) {
            return POSITION_NONE;
        } else {
            return index;
        }
    }

   public void addItem(Item item) {
        items.add(item);
        notifyDataSetChanged();
    }

    public void removeItem(int position) {
        items.remove(position);

        removing = true;
        notifyDataSetChanged();
        removing = false;
    }
}

This solution only uses a hack in case of removing an item. Otherwise (e.g. when adding an item) it retains the cleanliness and performance of an original code.

Of course, from the outside of the adapter, you call only addItem/removeItem, no need to call notifyDataSetChanged().

Go to Environmental Variables you will find this in Computer Properties->Advance system Setting->Environmental Variables -> Path

Add the path of your git installed int the system. eg: "C:\Program Files\Git\cmd"

Save it. Good to go now!!

Besides calling omp_get_num_threads() outside of the parallel region in your case, calling omp_set_num_threads() still doesn't guarantee that the OpenMP runtime will use exactly the specified number of threads. omp_set_num_threads() is used to override the value of the environment variable OMP_NUM_THREADS and they both control the upper limit of the size of the thread team that OpenMP would spawn for all parallel regions (in the case of OMP_NUM_THREADS) or for any consequent parallel region (after a call to omp_set_num_threads()). There is something called dynamic teams that could still pick smaller number of threads if the run-time system deems it more appropriate. You can disable dynamic teams by calling omp_set_dynamic(0) or by setting the environment variable OMP_DYNAMIC to false.

To enforce a given number of threads you should disable dynamic teams and specify the desired number of threads with either omp_set_num_threads():

omp_set_dynamic(0);     // Explicitly disable dynamic teams
omp_set_num_threads(4); // Use 4 threads for all consecutive parallel regions
#pragma omp parallel ...
{
    ... 4 threads used here ...
}

or with the num_threads OpenMP clause:

omp_set_dynamic(0);     // Explicitly disable dynamic teams
// Spawn 4 threads for this parallel region only
#pragma omp parallel ... num_threads(4)
{
    ... 4 threads used here ...
}

There is no built-in functionality in VBS for that, however, you can use the FileSystemObject FileExists function for that :

Option Explicit
DIM fso    
Set fso = CreateObject("Scripting.FileSystemObject")

If (fso.FileExists("C:\Program Files\conf")) Then
  WScript.Echo("File exists!")
  WScript.Quit()
Else
  WScript.Echo("File does not exist!")
End If

WScript.Quit()

this.close_Button = (Button)this.findViewById(R.id.close);
   this.close_Button.setOnClickListener(new OnClickListener() {
     @Override
     public void onClick(View v) {
        finish();
     }
  });

finish() - Call this when your activity is done and should be closed. The ActivityResult is propagated back to whoever launched you via onActivityResult().

In your Jest configuration, add setupFilesAfterEnv: ["./setupTests.js"], create that file, and add the code you want to run before the tests:

// setupTests.js
window.crypto = {
   .....
};

Reference: setupFilesAfterEnv [array]

It seems to work, but maybe there is a simpler solution that works in all browsers?

What you put inside the </dependencies> tag of the root pom will be included by all child modules of the root pom. If all your modules use that dependency, this is the way to go.

However, if only 3 out of 10 of your child modules use some dependency, you do not want this dependency to be included in all your child modules. In that case, you can just put the dependency inside the </dependencyManagement>. This will make sure that any child module that needs the dependency must declare it in their own pom file, but they will use the same version of that dependency as specified in your </dependencyManagement> tag.

You can also use the </dependencyManagement> to modify the version used in transitive dependencies, because the version declared in the upper most pom file is the one that will be used. This can be useful if your project A includes an external project B v1.0 that includes another external project C v1.0. Sometimes it happens that a security breach is found in project C v1.0 which is corrected in v1.1, but the developers of B are slow to update their project to use v1.1 of C. In that case, you can simply declare a dependency on C v1.1 in your project's root pom inside `, and everything will be good (assuming that B v1.0 will still be able to compile with C v1.1).

 index.html

This is how I organized my application's static resources.

if you have CRUD (index) and you need set default sorting your controller for GridView, or ListView, or more... Example

public function actionIndex()
{
    $searchModel = new NewsSearch();
    $dataProvider = $searchModel->search(Yii::$app->request->queryParams);
    // set default sorting
    $dataProvider->sort->defaultOrder = ['id' => SORT_DESC];

    return $this->render('index', [
        'searchModel' => $searchModel,
        'dataProvider' => $dataProvider,
    ]);
}

you need add

$dataProvider->sort->defaultOrder = ['id' => SORT_DESC];

START "notepad.exe"
echo Will launch the notepad.exe application
PAUSE

To make any cmd file type, all you have to do is save the contents as .bat, i.e.

@echo
TITLE example.bat
PAUSE
taskkill/IM cmd.exe

Make that into an "example.bat" file, save it, then open it and run.

Well, for any numbers in Javascript I use next one:

var a = "1222333444555666777888999";
a = a.replace(new RegExp("^(\\d{" + (a.length%3?a.length%3:0) + "})(\\d{3})", "g"), "$1 $2").replace(/(\d{3})+?/gi, "$1 ").trim();

and if you need to use any other separator as comma for example:

var sep = ",";
a = a.replace(/\s/g, sep);

or as a function:

function numberFormat(_number, _sep) {
    _number = typeof _number != "undefined" && _number > 0 ? _number : "";
    _number = _number.replace(new RegExp("^(\\d{" + (_number.length%3? _number.length%3:0) + "})(\\d{3})", "g"), "$1 $2").replace(/(\d{3})+?/gi, "$1 ").trim();
    if(typeof _sep != "undefined" && _sep != " ") {
        _number = _number.replace(/\s/g, _sep);
    }
    return _number;
}

This is my awesome solution for a div with a dynamic (percentaged) height.

CSS

.vertical_placer{
  background:red;
  position:absolute; 
  height:43%; 
  width:100%;
  display: table;
}

.inner_placer{  
  display: table-cell;
  vertical-align: middle;
  text-align:center;
}

.inner_placer svg{
  position:relative;
  color:#fff;
  background:blue;
  width:30%;
  min-height:20px;
  max-height:60px;
  height:20%;
}

HTML

<div class="footer">
    <div class="vertical_placer">
        <div class="inner_placer">
            <svg> some Text here</svg>
        </div>
    </div>
</div>  

Try this by yourself.

I know there have been a lot of answers submitted, but none of them seemed to really nail the problem. Here is my take at a solution:

1. Use the <form method="get"> method that the OP is starting with. This works really well, but it sometimes appends a ? to the URL. The ? is the main problem.
2. This solution works without JavaScript enabled. The fallback will add a ? to the end of the URL though.
3. If JavaScript is enabled then you can use jQuery/JavaScript to handle following the link, so that ? doesn't end up appended to the URL. It will seamlessly fallback to the <form> method for the very small fraction of users who don't have JavaScript enabled.
4. The JavaScript code uses event delegation so you can attach an event listener before the <form> or <button> even exist. I'm using jQuery in this example, because it is quick and easy, but it can be done in 'vanilla' JavaScript as well.
5. The JavaScript code prevents the default action from happening and then follows the link given in the <form> action attribute.

JSBin Example (code snippet can't follow links)

// Listen for any clicks on an element in the document with the `link` class
$(document).on('click', '.link', function(e) {
    // Prevent the default action (e.g. submit the form)
    e.preventDefault();

    // Get the URL specified in the form
    var url = e.target.parentElement.action;
    window.location = url;
});

<!DOCTYPE html>

    <head>
        <script src="https://code.jquery.com/jquery-1.11.1.min.js"></script>

    </head>
    <body>
        <!-- Set `action` to the URL you want the button to go to -->
        <form method="get" action="http://stackoverflow.com/questions/2906582/how-to-create-an-html-button-that-acts-like-a-link">
            <!-- Add the class `link` to the button for the event listener -->
            <button type="submit" class="link">Link</button>
        </form>
    </body>
</html>

You can create a StreamReader around the stream, then call StreamReader.ReadToEnd().

StreamReader responseReader = new StreamReader(request.GetResponse().GetResponseStream());
var responseData = responseReader.ReadToEnd();

I have build a small demo project on this you could have a look to it Link to project

I also recently had this problem and I solved it by rebooting Android Studio. But my friend had to have the original cable for his device, no other cables worked.

if you open localhost/phpmyadmin you will find a tab called "User accounts". There you can define all your users that can access the mysql database, set their rights and even limit from where they can connect.

Try Like this.

tv1.setText("  " + Integer.toString(X[i]) + "\n" + "+" + " " + Integer.toString(Y[i]));

To make it into a one liner you can try something like:

svn status | cut -d ' ' -f 8 | xargs svn revert

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

Or alternatively if you have the XML in a string use the LoadXml method.

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>[email protected]</Email>
    </Company>
</Data>

After researching everywhere finally i have found out temporary solution. Because i have try all the solution installing access drivers but still i am facing same issues.

For excel source, Before this step you need to change the setting. Save excel file as 2010 format.xlsx

Also set Project Configuration Properties for Debugging Run64BitRuntime = False

1. Drag and drop the excel source
2. Double click on the excel source and connect excel. Any way you will get an same error no table or view cannot load....
3. Click ok
4. Right click on excel source, click on show advanced edit.
5. In that click on component properties.
6. You can see openrowset. In that right side you need to enter you excel sheet name example: if in excel sheet1 then you need to enter sheet1$. I.e end with dollar symbol. And click ok.
7. Now you can do other works connecting to destination.

Brian's answer (a custom function) is the correct and simplest thing to do in general.

But if you really wanted to define a numeric type with a (non-standard) '%' operator, like desk calculators do, so that 'X % Y' means X * Y / 100.0, then from Python 2.6 onwards you can redefine the mod() operator:

import numbers

class MyNumberClasswithPct(numbers.Real):
    def __mod__(self,other):
        """Override the builtin % to give X * Y / 100.0 """
        return (self * other)/ 100.0
    # Gotta define the other 21 numeric methods...
    def __mul__(self,other):
        return self * other # ... which should invoke other.__rmul__(self)
    #...

This could be dangerous if you ever use the '%' operator across a mixture of MyNumberClasswithPct with ordinary integers or floats.

What's also tedious about this code is you also have to define all the 21 other methods of an Integral or Real, to avoid the following annoying and obscure TypeError when you instantiate it

("Can't instantiate abstract class MyNumberClasswithPct with abstract methods __abs__,  __add__, __div__, __eq__, __float__, __floordiv__, __le__, __lt__, __mul__,  __neg__, __pos__, __pow__, __radd__, __rdiv__, __rfloordiv__, __rmod__, __rmul__,  __rpow__, __rtruediv__, __truediv__, __trunc__")

I tried pydiction (didn't work for me) and the normal omnicompletion (too limited). I looked into Jedi as suggested but found it too complex to set up. I found python-mode, which in the end satisfied my needs. Thanks @klen.

One liner for Swift:

NSAttributedString(string: "Red Text", attributes: [.foregroundColor: UIColor.red])

You can do this by using below code

<HorizontalScrollView
                    android:layout_width="match_parent"
                    android:layout_height="match_parent">
                    <ScrollView
                        android:layout_width="wrap_content"
                        android:layout_height="match_parent">
                        <LinearLayout
                            android:layout_width="match_parent"
                            android:layout_height="wrap_content">
                            
                        </LinearLayout>
                    </ScrollView>
    </HorizontalScrollView>

You have to set you distribution type. In your code, juste add:

self.stack1.distribution = UIStackViewDistributionFillEqually;

Or you can set the distribution directly in your interface builder. For example:

Hope that helps ;) Lapinou.

interestingly my favorite solution to this problem isn't yet mentioned here: using floats.

html:

<div class="parent">
    <div class="child"></div>
</div>

css:

.parent{width:100px; height:100px;}
.child{float:left; margin-top:20px; width:50px; height:50px;}

see it here: http://codepen.io/anon/pen/Iphol

note that in case you need dynamic height on the parent, it also has to float, so simply replace height:100px; by float:left;

Again, old thread, but here's my solution using a generator and plain str.find.

def findall(p, s):
    '''Yields all the positions of
    the pattern p in the string s.'''
    i = s.find(p)
    while i != -1:
        yield i
        i = s.find(p, i+1)

Example

x = 'banananassantana'
[(i, x[i:i+2]) for i in findall('na', x)]

returns

[(2, 'na'), (4, 'na'), (6, 'na'), (14, 'na')]

This simple extension worked beautifully for me. I just had to make sure that MyObject was IComparable. When the sort method is called on the observable collection of MyObjects, the CompareTo method on MyObject is called, which calls my Logical Sort method. While it doesn't have all the bells and whistles of the rest of the answers posted here, it's exactly what I needed.

static class Extensions
{
    public static void Sort<T>(this ObservableCollection<T> collection) where T : IComparable
    {
        List<T> sorted = collection.OrderBy(x => x).ToList();
        for (int i = 0; i < sorted.Count(); i++)
            collection.Move(collection.IndexOf(sorted[i]), i);
    }
}

public class MyObject: IComparable
{
    public int CompareTo(object o)
    {
        MyObject a = this;
        MyObject b = (MyObject)o;
        return Utils.LogicalStringCompare(a.Title, b.Title);
    }

    public string Title;

}
  .
  .
  .
myCollection = new ObservableCollection<MyObject>();
//add stuff to collection
myCollection.Sort();

One option is to find one of the various utilities that can change the window state of the currently running console window and make a call to it from within the batch script.

You can run it as the first thing in your batch script. Here are two such tools:

min.exe http://www.paulsadowski.com/wsh/cmdprogs.htm

cmdow http://www.commandline.co.uk/cmdow/index.html

if (condition){ // where condition evaluates to true 
    return false
}

If you want to set styles of all elements in body you should use next code^

  body{
    color: green;
    }

You could use WITH to define your expressions. Then do a simple Sub-SELECT to access those definitions.

CREATE VIEW MyView
AS
  WITH MyVars (SomeVar, Var2)
  AS (
    SELECT
      'something' AS 'SomeVar',
      123 AS 'Var2'
  )

  SELECT *
  FROM MyTable
  WHERE x = (SELECT SomeVar FROM MyVars)

This is what matplotlib.pyplot.scatter is for.

As a quick example:

import matplotlib.pyplot as plt
import numpy as np

# Generate data...
t = np.linspace(0, 2 * np.pi, 20)
x = np.sin(t)
y = np.cos(t)

plt.scatter(t,x,c=y)
plt.show()

Support for Python 3 was added in NumPy version 1.5.0, so to begin with, you must download/install a newer version of NumPy.

Might be a little too late to the party, but hope this helps someone with similar issue.

The reason why your default value doesnt't work is because the migration file sets up the default value in your database (MySQL or PostgreSQL or whatever), and not in your Laravel application.

Let me illustrate with an example.

This line means Laravel is generating a new Book instance, as specified in your model. The new Book object will have properties according to the table associated with the model. Up until this point, nothing is written on the database.

$book = new Book();

Now the following lines are setting up the values of each property of the Book object. Same still, nothing is written on the database yet.

$book->author = 'Test'
$book->title = 'Test'

This line is the one writing to the database. After passing on the object to the database, then the empty fields will be filled by the database (may be default value, may be null, or whatever you specify on your migration file).

$book->save();

And thus, the default value will not pop up before you save it to the database.

But, that is not enough. If you try to access $book->price, it will still be null (or 0, i'm not sure). Saving it is only adding the defaults to the record in the database, and it won't affect the Object you are carrying around.

So, to get the instance with filled-in default values, you have to re-fetch the instance. You may use the

Book::find($book->id);

Or, a more sophisticated way by refreshing the instance

$book->refresh();

And then, the next time you try to access the object, it will be filled with the default values.

select
datediff(millisecond,'2010-01-22 15:29:55.090','2010-01-22 15:30:09.153') / 1000.0 as Secs

result:
Secs
14.063

Just thought I'd mention it.

Look in HTML output for actual client ID

You need to look in the generated HTML output to find out the right client ID. Open the page in browser, do a rightclick and View Source. Locate the HTML representation of the JSF component of interest and take its id as client ID. You can use it in an absolute or relative way depending on the current naming container. See following chapter.

Note: if it happens to contain iteration index like :0:, :1:, etc (because it's inside an iterating component), then you need to realize that updating a specific iteration round is not always supported. See bottom of answer for more detail on that.

Memorize NamingContainer components and always give them a fixed ID

If a component which you'd like to reference by ajax process/execute/update/render is inside the same NamingContainer parent, then just reference its own ID.

<h:form id="form">
    <p:commandLink update="result"> <!-- OK! -->
    <h:panelGroup id="result" />
</h:form>

If it's not inside the same NamingContainer, then you need to reference it using an absolute client ID. An absolute client ID starts with the NamingContainer separator character, which is by default :.

<h:form id="form">
    <p:commandLink update="result"> <!-- FAIL! -->
</h:form>
<h:panelGroup id="result" />

<h:form id="form">
    <p:commandLink update=":result"> <!-- OK! -->
</h:form>
<h:panelGroup id="result" />

<h:form id="form">
    <p:commandLink update=":result"> <!-- FAIL! -->
</h:form>
<h:form id="otherform">
    <h:panelGroup id="result" />
</h:form>

<h:form id="form">
    <p:commandLink update=":otherform:result"> <!-- OK! -->
</h:form>
<h:form id="otherform">
    <h:panelGroup id="result" />
</h:form>

NamingContainer components are for example <h:form>, <h:dataTable>, <p:tabView>, <cc:implementation> (thus, all composite components), etc. You recognize them easily by looking at the generated HTML output, their ID will be prepended to the generated client ID of all child components. Note that when they don't have a fixed ID, then JSF will use an autogenerated ID in j_idXXX format. You should absolutely avoid that by giving them a fixed ID. The OmniFaces NoAutoGeneratedIdViewHandler may be helpful in this during development.

If you know to find the javadoc of the UIComponent in question, then you can also just check in there whether it implements the NamingContainer interface or not. For example, the HtmlForm (the UIComponent behind <h:form> tag) shows it implements NamingContainer, but the HtmlPanelGroup (the UIComponent behind <h:panelGroup> tag) does not show it, so it does not implement NamingContainer. Here is the javadoc of all standard components and here is the javadoc of PrimeFaces.

Solving your problem

So in your case of:

<p:tabView id="tabs"><!-- This is a NamingContainer -->
    <p:tab id="search"><!-- This is NOT a NamingContainer -->
        <h:form id="insTable"><!-- This is a NamingContainer -->
            <p:dialog id="dlg"><!-- This is NOT a NamingContainer -->
                <h:panelGrid id="display">

The generated HTML output of <h:panelGrid id="display"> looks like this:

<table id="tabs:insTable:display">

You need to take exactly that id as client ID and then prefix with : for usage in update:

<p:commandLink update=":tabs:insTable:display">

Referencing outside include/tagfile/composite

If this command link is inside an include/tagfile, and the target is outside it, and thus you don't necessarily know the ID of the naming container parent of the current naming container, then you can dynamically reference it via UIComponent#getNamingContainer() like so:

<p:commandLink update=":#{component.namingContainer.parent.namingContainer.clientId}:display">

Or, if this command link is inside a composite component and the target is outside it:

<p:commandLink update=":#{cc.parent.namingContainer.clientId}:display">

Or, if both the command link and target are inside same composite component:

<p:commandLink update=":#{cc.clientId}:display">

See also Get id of parent naming container in template for in render / update attribute

How does it work under the covers

This all is specified as "search expression" in the UIComponent#findComponent() javadoc:

A search expression consists of either an identifier (which is matched exactly against the id property of a UIComponent, or a series of such identifiers linked by the UINamingContainer#getSeparatorChar character value. The search algorithm should operates as follows, though alternate alogrithms may be used as long as the end result is the same:

• Identify the UIComponent that will be the base for searching, by stopping as soon as one of the following conditions is met:
  • If the search expression begins with the the separator character (called an "absolute" search expression), the base will be the root UIComponent of the component tree. The leading separator character will be stripped off, and the remainder of the search expression will be treated as a "relative" search expression as described below.
  • Otherwise, if this UIComponent is a NamingContainer it will serve as the basis.
  • Otherwise, search up the parents of this component. If a NamingContainer is encountered, it will be the base.
  • Otherwise (if no NamingContainer is encountered) the root UIComponent will be the base.
• The search expression (possibly modified in the previous step) is now a "relative" search expression that will be used to locate the component (if any) that has an id that matches, within the scope of the base component. The match is performed as follows:
  • If the search expression is a simple identifier, this value is compared to the id property, and then recursively through the facets and children of the base UIComponent (except that if a descendant NamingContainer is found, its own facets and children are not searched).
  • If the search expression includes more than one identifier separated by the separator character, the first identifier is used to locate a NamingContainer by the rules in the previous bullet point. Then, the findComponent() method of this NamingContainer will be called, passing the remainder of the search expression.

Note that PrimeFaces also adheres the JSF spec, but RichFaces uses "some additional exceptions".

"reRender" uses UIComponent.findComponent() algorithm (with some additional exceptions) to find the component in the component tree.

Those additional exceptions are nowhere in detail described, but it's known that relative component IDs (i.e. those not starting with :) are not only searched in the context of the closest parent NamingContainer, but also in all other NamingContainer components in the same view (which is a relatively expensive job by the way).

Never use prependId="false"

If this all still doesn't work, then verify if you aren't using <h:form prependId="false">. This will fail during processing the ajax submit and render. See also this related question: UIForm with prependId="false" breaks <f:ajax render>.

Referencing specific iteration round of iterating components

It was for long time not possible to reference a specific iterated item in iterating components like <ui:repeat> and <h:dataTable> like so:

<h:form id="form">
    <ui:repeat id="list" value="#{['one','two','three']}" var="item">
        <h:outputText id="item" value="#{item}" /><br/>
    </ui:repeat>

    <h:commandButton value="Update second item">
        <f:ajax render=":form:list:1:item" />
    </h:commandButton>
</h:form>

However, since Mojarra 2.2.5 the <f:ajax> started to support it (it simply stopped validating it; thus you would never face the in the question mentioned exception anymore; another enhancement fix is planned for that later).

This only doesn't work yet in current MyFaces 2.2.7 and PrimeFaces 5.2 versions. The support might come in the future versions. In the meanwhile, your best bet is to update the iterating component itself, or a parent in case it doesn't render HTML, like <ui:repeat>.

When using PrimeFaces, consider Search Expressions or Selectors

PrimeFaces Search Expressions allows you to reference components via JSF component tree search expressions. JSF has several builtin:

• @this: current component
• @form: parent UIForm
• @all: entire document
• @none: nothing

PrimeFaces has enhanced this with new keywords and composite expression support:

• @parent: parent component
• @namingcontainer: parent UINamingContainer
• @widgetVar(name): component as identified by given widgetVar

You can also mix those keywords in composite expressions such as @form:@parent, @this:@parent:@parent, etc.

PrimeFaces Selectors (PFS) as in @(.someclass) allows you to reference components via jQuery CSS selector syntax. E.g. referencing components having all a common style class in the HTML output. This is particularly helpful in case you need to reference "a lot of" components. This only prerequires that the target components have all a client ID in the HTML output (fixed or autogenerated, doesn't matter). See also How do PrimeFaces Selectors as in update="@(.myClass)" work?

In Typescript use the For Each like below.

selectChildren(data, $event) {
let parentChecked = data.checked;
for(var obj in this.hierarchicalData)
    {
        for (var childObj in obj )
        {
            value.checked = parentChecked;
        }
    }
}

<a onclick="navigator.app.loadUrl('https://google.com/', { openExternal:true });">Link</a>

In SQL, the order of the output is not defined unless you specify it in the ORDER BY clause.

Try this:

SELECT  *
