Solution 1 - you need to change your backend to accept your incoming requests

Solution 2 - using Angular proxy see here

Please note this is only for ng serve, you can't use proxy in ng build

Note: the reason it's working via postman is postman doesn't send preflight requests while your browser does.

Install Certificates.command on your mac.

$ 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/

Simple Solution::

use {nativeQuery=true} in your query.

for example

  @Query(value = "select d.id,d.name,d.breed,d.origin from Dog d",nativeQuery = true)
        
    List<Dog> findALL();

I encountered the same issue and all I had to do was to place the Application in a package one level higher than the service, dao and domain packages.

I fixed the problem adding this line @ComponentScan(basePackages = {"com.example.DemoApplication"}) to main class file, just up from the class name

package com.example.demo;_x000D_
_x000D_
import org.springframework.boot.SpringApplication;_x000D_
import org.springframework.boot.autoconfigure.SpringBootApplication;_x000D_
import org.springframework.context.annotation.ComponentScan;_x000D_
_x000D_
@SpringBootApplication_x000D_
@ComponentScan(basePackages = {"com.example.DemoApplication"})_x000D_
public class DemoApplication {_x000D_
_x000D_
 public static void main(String[] args) {_x000D_
  SpringApplication.run(DemoApplication.class, args);_x000D_
 }_x000D_
_x000D_
}

Basically this happens when you have your Class Application in "another package". For example:

com.server
 - Applicacion.class (<--this class have @ComponentScan)
com.server.config
 - MongoConfig.class 
com.server.repository
 - UserRepository

I solve the problem with this in the Application.class

@SpringBootApplication
@ComponentScan ({"com.server", "com.server.config"})
@EnableMongoRepositories ("com.server.repository") // this fix the problem

Another less elegant way is to: put all the configuration classes in the same package.

You could embed the '' default in your regex by adding |$:

>>> re.findall('\d+|$', 'aa33bbb44')[0]
'33'
>>> re.findall('\d+|$', 'aazzzbbb')[0]
''
>>> re.findall('\d+|$', '')[0]
''

Also works with re.search pointed out by others:

>>> re.search('\d+|$', 'aa33bbb44').group()
'33'
>>> re.search('\d+|$', 'aazzzbbb').group()
''
>>> re.search('\d+|$', '').group()
''

In sequelize you can easily add order by clauses.

exports.getStaticCompanies = function () {
    return Company.findAll({
        where: {
            id: [46128, 2865, 49569,  1488,   45600,   61991,  1418,  61919,   53326,   61680]
        }, 
        // Add order conditions here....
        order: [
            ['id', 'DESC'],
            ['name', 'ASC'],
        ],
        attributes: ['id', 'logo_version', 'logo_content_type', 'name', 'updated_at']
    });
};

See how I've added the order array of objects?

order: [
      ['COLUMN_NAME_EXAMPLE', 'ASC'], // Sorts by COLUMN_NAME_EXAMPLE in ascending order
],

Edit:

You might have to order the objects once they've been recieved inside the .then() promise. Checkout this question about ordering an array of objects based on a custom order:

How do I sort an array of objects based on the ordering of another array?

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)

For me running these three commands fix the issue on my Mac:

export ANDROID_HOME=~/Library/Android/sdk
export PATH=${PATH}:${ANDROID_HOME}/tools
export PATH=${PATH}:${ANDROID_HOME}/platform-tools

For ease of copying here's one-liner

export ANDROID_HOME=~/Library/Android/sdk && export PATH=${PATH}:${ANDROID_HOME}/tools && export PATH=${PATH}:${ANDROID_HOME}/platform-tools

To add Permanently

Follow these steps:

1. Open the .bash_profile file in your home directory (for example, /Users/your-user-name/.bash_profile) in a text editor.
2. Add export PATH="The above exports here" to the last line of the file, where your-dir is the directory you want to add.
3. Save the .bash_profile file.
4. Restart your terminal

Adding to bash process for different systems

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).

You want to convert html (a byte-like object) into a string using .decode, e.g. html = response.read().decode('utf-8').

See Convert bytes to a Python String

According to Vlad Mihalcea (see https://vladmihalcea.com/hibernate-facts-the-importance-of-fetch-strategy/):

JPQL queries may override the default fetching strategy. If we don’t explicitly declare what we want to fetch using inner or left join fetch directives, the default select fetch policy is applied.

It seems that JPQL query might override your declared fetching strategy so you'll have to use join fetch in order to eagerly load some referenced entity or simply load by id with EntityManager (which will obey your fetching strategy but might not be a solution for your use case).

In the spring boot reference,it said:

When a class doesn’t include a package declaration it is considered to be in the “default package”. The use of the “default package” is generally discouraged, and should be avoided. It can cause particular problems for Spring Boot applications that use @ComponentScan, @EntityScan or @SpringBootApplication annotations, since every class from every jar, will be read.

com
 +- example
     +- myproject
         +- Application.java
         |
         +- domain
         |   +- Customer.java
         |   +- CustomerRepository.java
         |
         +- service
         |   +- CustomerService.java
         |
         +- web
             +- CustomerController.java

In your cases. You must add scanBasePackages in the @SpringBootApplication annotation.just like@SpringBootApplication(scanBasePackages={"domain","contorller"..})

IntVar = int("".join(filter(str.isdigit, StringVar)))

I am late for this but i want put some more solution relevant to this.

 @GetMapping
public ResponseEntity<List<JSONObject>> getRole() {
    return ResponseEntity.ok(service.getRole());
}

Combining all answers above, you can write reusable code with BaseEntity:

@Data
@NoArgsConstructor
@MappedSuperclass
public abstract class BaseEntity {

  @Transient
  public static final Sort SORT_BY_CREATED_AT_DESC = 
                        Sort.by(Sort.Direction.DESC, "createdAt");

  @Id
  private Long id;
  private LocalDateTime createdAt;
  private LocalDateTime updatedAt;

  @PrePersist
  void prePersist() {
    this.createdAt = LocalDateTime.now();
  }

  @PreUpdate
  void preUpdate() {
    this.updatedAt = LocalDateTime.now();
  }
}

DAO object overloads findAll method - basically, still uses findAll()

public interface StudentDAO extends CrudRepository<StudentEntity, Long> {

  Iterable<StudentEntity> findAll(Sort sort);

}

StudentEntity extends BaseEntity which contains repeatable fields (maybe you want to sort by ID, as well)

@Getter
@Setter
@FieldDefaults(level = AccessLevel.PRIVATE)
@Entity
class StudentEntity extends BaseEntity {

  String firstName;
  String surname;

}

Finally, the service and usage of SORT_BY_CREATED_AT_DESC which probably will be used not only in the StudentService.

@Service
class StudentService {

  @Autowired
  StudentDAO studentDao;

  Iterable<StudentEntity> findStudents() {
    return this.studentDao.findAll(SORT_BY_CREATED_AT_DESC);
  }
}

Hat tip to Adam Bien if you don't want to use createQuery with a String and want type safety:

 @PersistenceContext
 EntityManager em;

 public List<ConfigurationEntry> allEntries() {
        CriteriaBuilder cb = em.getCriteriaBuilder();
        CriteriaQuery<ConfigurationEntry> cq = cb.createQuery(ConfigurationEntry.class);
        Root<ConfigurationEntry> rootEntry = cq.from(ConfigurationEntry.class);
        CriteriaQuery<ConfigurationEntry> all = cq.select(rootEntry);
        TypedQuery<ConfigurationEntry> allQuery = em.createQuery(all);
        return allQuery.getResultList();
 }

Receiving a status 429 is not an error, it is the other server "kindly" asking you to please stop spamming requests. Obviously, your rate of requests has been too high and the server is not willing to accept this.

You should not seek to "dodge" this, or even try to circumvent server security settings by trying to spoof your IP, you should simply respect the server's answer by not sending too many requests.

If everything is set up properly, you will also have received a "Retry-after" header along with the 429 response. This header specifies the number of seconds you should wait before making another call. The proper way to deal with this "problem" is to read this header and to sleep your process for that many seconds.

You can find more information on status 429 here: http://tools.ietf.org/html/rfc6585#page-3

you can use the query options {raw: true} to return the raw result. Your query should like follows:

db.Sensors.findAll({
  where: {
    nodeid: node.nodeid
  },
  raw: true,
})

also if you have associations with include that gets flattened. So, we can use another parameter nest:true

db.Sensors.findAll({
  where: {
    nodeid: node.nodeid
  },
  raw: true,
  nest: true,
})

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.

See the docs about querying.

It would be:

$or: [{a: 5}, {a: 6}]  // (a = 5 OR a = 6)

This has been an old question but solution is very simple to that. If you are ever unsure about how to write criterias, joins etc in hibernate then best way is using native queries. This doesn't slow the performance and very useful. Eq. below

    @Query(nativeQuery = true, value = "your sql query")
returnTypeOfMethod methodName(arg1, arg2);

If you are using ENUM like MessageStatus, you may need a converter. Just add this class:

import javax.persistence.AttributeConverter;
import javax.persistence.Converter;

/**
 * Convert ENUM type in JPA.
 */
@Converter(autoApply = true)
public class MessageStatusConverter implements AttributeConverter<MessageStatus, Integer> {
  @Override
  public Integer convertToDatabaseColumn(MessageStatus messageStatus) {
    return messageStatus.getValue();
  }

  @Override
  public MessageStatus convertToEntityAttribute(Integer i) {
    return MessageStatus.valueOf(i);
  }
}

Warning: This might inflate executable file size a little bit and cost a little runtime performance. IMO, this would be better if golang has such feature like macro or function decorator.

If you want to mock functions without changing its API, the easiest way is to change the implementation a little bit:

func getPage(url string) string {
  if GetPageMock != nil {
    return GetPageMock()
  }

  // getPage real implementation goes here!
}

func downloader() {
  if GetPageMock != nil {
    return GetPageMock()
  }

  // getPage real implementation goes here!
}

var GetPageMock func(url string) string = nil
var DownloaderMock func() = nil

This way we can actually mock one function out of the others. For more convenient we can provide such mocking boilerplate:

// download.go
func getPage(url string) string {
  if m.GetPageMock != nil {
    return m.GetPageMock()
  }

  // getPage real implementation goes here!
}

func downloader() {
  if m.GetPageMock != nil {
    return m.GetPageMock()
  }

  // getPage real implementation goes here!
}

type MockHandler struct {
  GetPage func(url string) string
  Downloader func()
}

var m *MockHandler = new(MockHandler)

func Mock(handler *MockHandler) {
  m = handler
}

In test file:

// download_test.go
func GetPageMock(url string) string {
  // ...
}

func TestDownloader(t *testing.T) {
  Mock(&MockHandler{
    GetPage: GetPageMock,
  })

  // Test implementation goes here!

  Mock(new(MockHandler)) // Reset mocked functions
}

Following with Oleg answer, if you want to find ALL objects in a List filtered by a property, you could do something like:

//Search into a generic list ALL items with a generic property
public final class SearchTools {
       public static <T> List<T> findByProperty(Collection<T> col, Predicate<T> filter) {
           List<T> filteredList = (List<T>) col.stream().filter(filter).collect(Collectors.toList());
           return filteredList;
     }

//Search in the list "listItems" ALL items of type "Item" with the specific property "iD_item=itemID"
public static final class ItemTools {
         public static List<Item> findByItemID(Collection<Item> listItems, String itemID) {
             return SearchTools.findByProperty(listItems, item -> itemID.equals(item.getiD_Item()));
         }
     }
}

and similarly if you want to filter ALL items in a HashMap with a certain Property

//Search into a MAP ALL items with a given property
public final class SearchTools {
       public static <T> HashMap<String,T> filterByProperty(HashMap<String,T> completeMap, Predicate<? super Map.Entry<String,T>> filter) {
           HashMap<String,T> filteredList = (HashMap<String,T>) completeMap.entrySet().stream()
                                .filter(filter)
                                .collect(Collectors.toMap(map -> map.getKey(), map -> map.getValue()));
           return filteredList;
     }

     //Search into the MAP ALL items with specific properties
public static final class ItemTools {

        public static HashMap<String,Item> filterByParentID(HashMap<String,Item> mapItems, String parentID) {
            return SearchTools.filterByProperty(mapItems, mapItem -> parentID.equals(mapItem.getValue().getiD_Parent()));
        }

        public static HashMap<String,Item> filterBySciName(HashMap<String,Item> mapItems, String sciName) {
            return SearchTools.filterByProperty(mapItems, mapItem -> sciName.equals(mapItem.getValue().getSciName()));
        }
    }

As @Lighthart as shown, yes it's possible, although it adds significant fat to the controller and isn't DRY.

You should really define your own query in the entity repository, it's simple and best practice.

use Doctrine\ORM\EntityRepository;

class UserRepository extends EntityRepository
{
    public function findAll()
    {
        return $this->findBy(array(), array('username' => 'ASC'));
    }
}

Then you must tell your entity to look for queries in the repository:

/**
 * @ORM\Table(name="User")
 * @ORM\Entity(repositoryClass="Acme\UserBundle\Entity\Repository\UserRepository")
 */
class User
{
    ...
}

Finally, in your controller:

$this->getDoctrine()->getRepository('AcmeBundle:User')->findAll();

You can use .contents:

>>> for hit in soup.findAll(attrs={'class' : 'MYCLASS'}):
...     print hit.contents[6].strip()
... 
THIS IS MY TEXT

You can try in two ways. The detail is in this link.

1) Via pip

pip install --upgrade certifi

2) If it doesn't work, try to run a Cerificates.command that comes bundled with Python 3.* for Mac:(Go to your python installation location and double click the file)

open /Applications/Python\ 3.*/Install\ Certificates.command

'lines' term from your snippet consists of set of strings.

 lines = f.readlines()
 match = re.findall('[A-Z]+', lines)

You cannot send entire lines into the re.findall('pattern',<string>)

You can try to send line by line

 for i in lines:
  match = re.findall('[A-Z]+', i)
  print match

or to convert the entire lines collection into single line (each line seperated by space)

 NEW_LIST=' '.join(lines)
 match=re.findall('[A-Z]+' ,NEW_LIST)
 print match

This might help you

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.

Just use simple properties.

var tomorrow = currentDateTime.Date + 1;  
var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
                            .Where(x =>  x.DateTimeStart >= currentDateTime.Date 
                                   and x.DateTimeStart < tomorrow);

If future dates are not possible in your app, then >= x.DateTimeStart >= currentDateTime.Date is sufficient.

if you have more complex date comparisons, then check Canonical functions and if you have EF6+ DB functions

More Generally - For people searching for issues Supported Linq methods in EF can explain similar issues with linq statements that work on Memory base Lists but not in EF.

for i in range (1, len(list))
    try:
        print (list[i])

    except ValueError:
        print("Error Value.")
    except indexError:
        print("Erorr index")
    except :
        print('error ')

I would suggest going the lxml route and using xpath.

from lxml import etree
# data is the variable containing the html
data = etree.HTML(data)
anchor = data.xpath('//a[@class="title"]/text()')

Try using rextract. It will let you extract text using a regular expression and reformat it.

Example:

$ echo "This is 02G05 a test string 20-Jul-2012" | ./rextract '([\d]+G[\d]+)' '${1}'

2G05

I can confirm that there is no XPath support within Beautiful Soup.

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

Just to add some alternate, you could do like this also:

$id =101;
$criteria = new CDbCriteria();
$criteria->condition = "email_id =:email_id";
$criteria->params = array(':email_id' => $id);
$comments = EmailArchive::model()->findAll($criteria);

By default the route configuration follows RESTFul conventions meaning that it will accept only the Get, Post, Put and Delete action names (look at the route in global.asax => by default it doesn't allow you to specify any action name => it uses the HTTP verb to dispatch). So when you send a GET request to /api/users/authenticate you are basically calling the Get(int id) action and passing id=authenticate which obviously crashes because your Get action expects an integer.

If you want to have different action names than the standard ones you could modify your route definition in global.asax:

Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{action}/{id}",
    defaults: new { action = "get", id = RouteParameter.Optional }
);

Now you can navigate to /api/users/getauthenticate to authenticate the user.

Since you seem to be on windows you can do this so python <filename.py>. Check that python's bin folder is in your PATH, or you can do c:\python23\bin\python <filename.py>. Python is an interpretive language and so you need the interpretor to run your file, much like you need java runtime to run a jar file.

I have not used BeuatifulSoup but maybe the following can help in some tiny way.

import re
import urllib2
stuff = urllib2.urlopen(your_url_goes_here).read()  # stuff will contain the *entire* page

# Replace the string Python with your desired regex
results = re.findall('(Python)',stuff)

for i in results:
    print i

I'm not suggesting this is a replacement but maybe you can glean some value in the concept until a direct answer comes along.

Adding a combination of Chris Redford's and Amr's answer, you can also search for an attribute name with any value with the select command:

from bs4 import BeautifulSoup as Soup
html = '<td valign="top">.....</td>\
    <td width="580" valign="top">.......</td>\
    <td>.....</td>'
soup = Soup(html, 'lxml')
results = soup.select('td[valign]')

Here's a ES6 using Await / Async example:

    async deleteProduct(id) {

        if (!id) {
            return {msg: 'No Id specified..', payload: 1};
        }

        try {
            return !!await products.destroy({
                where: {
                    id: id
                }
            });
        } catch (e) {
            return false;
        }

    }

Please note that I'm using the !! Bang Bang Operator on the result of the await which will change the result into a Boolean.

you can replace your pattern with

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

The problem is in this line:

with pattern.findall(row) as f:

You are using the with statement. It requires an object with __enter__ and __exit__ methods. But pattern.findall returns a list, with tries to store the __exit__ method, but it can't find it, and raises an error. Just use

f = pattern.findall(row)

instead.

A referral was returned from the server error usually means that the IP address is not hosted by the domain that is provided on the connection string. For more detail, see this link:

Referral was returned AD Provider

To illustrate the problem, we define two IP addresses hosted on different domains:

IP Address DC Name Notes

172.1.1.10 ozkary.com Production domain

172.1.30.50 ozkaryDev.com Development domain

If we defined a LDAP connection string with this format:

LDAP://172.1.1.10:389/OU=USERS,DC=OZKARYDEV,DC=COM

This will generate the error because the IP is actually on the OZKARY DC not the OZKARYDEV DC. To correct the problem, we would need to use the IP address that is associated to the domain.

You're trying to open each file twice! First you do:

infile=open('110331_HS1A_1_rtTA.result','r')

and then you pass infile (which is a file object) to the open function again:

with open (infile, mode='r', buffering=-1)

open is of course expecting its first argument to be a file name, not an opened file!

Open the file once only and you should be fine.

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)
            .setParameter("endDate", endDate, TemporalType.DATE)
            .getResultList();

}

Try writting the lambda with the same conditions as the delegate. like this:

  List<AnalysisObject> analysisObjects = 
    analysisObjectRepository.FindAll().Where(
    (x => 
       (x.ID == packageId)
    || (x.Parent != null && x.Parent.ID == packageId)
    || (x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)
    ).ToList();

How to find elements by class

I'm having trouble parsing html elements with "class" attribute using Beautifulsoup.

You can easily find by one class, but if you want to find by the intersection of two classes, it's a little more difficult,

From the documentation (emphasis added):

If you want to search for tags that match two or more CSS classes, you should use a CSS selector:

css_soup.select("p.strikeout.body")
# [<p class="body strikeout"></p>]

To be clear, this selects only the p tags that are both strikeout and body class.

To find for the intersection of any in a set of classes (not the intersection, but the union), you can give a list to the class_ keyword argument (as of 4.1.2):

soup = BeautifulSoup(sdata)
class_list = ["stylelistrow"] # can add any other classes to this list.
# will find any divs with any names in class_list:
mydivs = soup.find_all('div', class_=class_list) 

Also note that findAll has been renamed from the camelCase to the more Pythonic find_all.

I resolved this by adding @Transactional to the base/generic Hibernate DAO implementation class (the parent class which implements the saveOrUpdate() method inherited by the DAO I use in the main program), i.e. the @Transactional needs to be specified on the actual class which implements the method. My assumption was instead that if I declared @Transactional on the child class then it included all of the methods that were inherited by the child class. However it seems that the @Transactional annotation only applies to methods implemented within a class and not to methods inherited by a class.

You can use .split()

numbers = raw_input().split(",")
print len(numbers)

This will still give you strings, but it will be a list of strings.

If you need to map them to a type, use list comprehension:

numbers = [int(n, 10) for n in raw_input().split(",")]
print len(numbers)

If you want to be able to enter in any Python type and have it mapped automatically and you trust your users IMPLICITLY then you can use eval

I would like to say that Microsoft LDAP has some special ways to search recursively for all of memberships of a user.

1. The Matching Rule you can specify for the "member" attribute. In particular, using the Microsoft Exclusive LDAP_MATCHING_RULE_IN_CHAIN rule for "member" attribute allows recursive/nested membership searching. The rule is used when you add it after the member attribute. Ex. (member:1.2.840.113556.1.4.1941:= XXXXX )

2. For the same Domain as the Account, The filter can use <SID=S-1-5-21-XXXXXXXXXXXXXXXXXXXXXXX> instead of an Accounts DistinguishedName attribute which is very handy to use cross domain if needed. HOWEVER it appears you need to use the ForeignSecurityPrincipal <GUID=YYYY> as it will not resolve your SID as it appears the <SID=> tag does not consider ForeignSecurityPrincipal object type. You can use the ForeignSecurityPrincipal DistinguishedName as well.

Using this knowledge, you can LDAP query those hard to get memberships, such as the "Domain Local" groups an Account is a member of but unless you looked at the members of the group, you wouldn't know if user was a member.

//Get Direct+Indirect Memberships of User (where SID is XXXXXX)

string str = "(& (objectCategory=group)(member:1.2.840.113556.1.4.1941:=<SID=XXXXXX>) )";

//Get Direct+Indirect **Domain Local** Memberships of User (where SID is XXXXXX)

string str2 = "(& (objectCategory=group)(|(groupType=-2147483644)(groupType=4))(member:1.2.840.113556.1.4.1941:=<SID=XXXXXX>) )";

//TAA DAA

Feel free to try these LDAP queries after substituting the SID of a user you want to retrieve all group memberships of. I figure this is similiar if not the same query as what the PowerShell Command Get-ADPrincipalGroupMembership uses behind the scenes. The command states "If you want to search for local groups in another domain, use the ResourceContextServer parameter to specify the alternate server in the other domain."

If you are familiar enough with C# and Active Directory, you should know how to perform an LDAP search using the LDAP queries provided.

• <SID> Binding String
• <GUID> Binding String

Instead of String.IndexOf, use String.Equals to ensure you don't have partial matches. Also don't use FindAll as that goes through every element, use FindIndex (it stops on the first one it hits).

if(testList.FindIndex(x => x.Equals(keyword,  
    StringComparison.OrdinalIgnoreCase) ) != -1) 
    Console.WriteLine("Found in list"); 

Alternately use some LINQ methods (which also stops on the first one it hits)

if( testList.Any( s => s.Equals(keyword, StringComparison.OrdinalIgnoreCase) ) )
    Console.WriteLine("found in list");

IIRC @Valid isn't a Spring annotation but a JSR-303 annotation (which is the Bean Validation standard). What it does is it basically checks if the data that you send to the method is valid or not (it will validate the scriptFile for you).

If you just want to find the position of all matches I'd like to point you to a little hack:

var haystack = 'I learned to play the Ukulele in Lebanon.',
    needle = 'le',
    splitOnFound = haystack.split(needle).map(function (culm)
    {
        return this.pos += culm.length + needle.length
    }, {pos: -needle.length}).slice(0, -1); // {pos: ...} – Object wich is used as this

console.log(splitOnFound);

It might not be applikable if you have a RegExp with variable length but for some it might be helpful.

This is case sensitive. For case insensitivity use String.toLowerCase function before.

you can also use this :

import requests
from bs4 import BeautifulSoup
import csv

url = "http://58.68.130.147/"
r = requests.get(url)
data = r.text

soup = BeautifulSoup(data, "html.parser")
get_details = soup.find_all("input", attrs={"name":"stainfo"})

for val in get_details:
    get_val = val["value"]
    print(get_val)

The simplest way to handle this case is by using getattr(). You can adapt this example to your needs:

from bs4 import BeautifulSoup

source_html = """
<span class="ratingsDisplay">
    <a class="ratingNumber" href="https://www.youtube.com/watch?v=oHg5SJYRHA0" target="_blank" rel="noopener">
        <span class="ratingsContent">3.7</span>
    </a>
</span>
"""

soup = BeautifulSoup(source_html, "lxml")
my_ratings = getattr(soup.find('span', {"class": "ratingsContent"}), "text", None)
print(my_ratings)

This will find the text element,"3.7", within the tag object <span class="ratingsContent">3.7</span> when it exists, however, default to NoneType when it does not.

getattr(object, name[, default])

Return the value of the named attribute of object. name must be a string. If the string is the name of one of the object’s attributes, the result is the value of that attribute. For example, getattr(x, 'foobar') is equivalent to x.foobar. If the named attribute does not exist, default is returned if provided, otherwise, AttributeError is raised.

I had to change my code from this:

 DirectoryEntry entry = new DirectoryEntry(path, ldapUser, ldapPassword);
 DirectorySearcher searcher = new DirectorySearcher();
 searcher.SearchRoot = entry;
 searcher.SearchScope = SearchScope.Subtree;

To this:

DirectoryEntry entry = new DirectoryEntry(path, ldapUser, ldapPassword);
DirectorySearcher searcher = new DirectorySearcher();
searcher.SearchScope = SearchScope.OneLevel;
SearchResult searchResult = searcher.FindOne();

The reason why your code is slow is that your LDAP query retrieves every single user object in your domain even though you're only interested in one user with a common name of "Adit":

dSearcher.Filter = "(&(objectClass=user))";

So to optimize, you need to narrow your LDAP query to just the user you are interested in. Try something like:

dSearcher.Filter = "(&(objectClass=user)(cn=Adit))";

In addition, don't forget to dispose these objects when done:

• DirectoryEntry dEntry
• DirectorySearcher dSearcher

For the complete list of attributes, the short answer is: no. The problem is that the attributes are actually defined as the arguments accepted by the getattr built-in function. As the user can reimplement __getattr__, suddenly allowing any kind of attribute, there is no possible generic way to generate that list. The dir function returns the keys in the __dict__ attribute, i.e. all the attributes accessible if the __getattr__ method is not reimplemented.

For the second question, it does not really make sense. Actually, methods are callable attributes, nothing more. You could though filter callable attributes, and, using the inspect module determine the class methods, methods or functions.

You should use the interface only if you need it, e.g., if your list is casted to an IList implementation other than List. This is true when, for example, you use NHibernate, which casts ILists into an NHibernate bag object when retrieving data.

If List is the only implementation that you will ever use for a certain collection, feel free to declare it as a concrete List implementation.

You can generate the XML documentation file using either the command-line compiler or through the Visual Studio interface. If you are compiling with the command-line compiler, use options /doc or /doc+. That will generate an XML file by the same name and in the same path as the assembly. To specify a different file name, use /doc:file.

If you are using the Visual Studio interface, there's a setting that controls whether the XML documentation file is generated. To set it, double-click My Project in Solution Explorer to open the Project Designer. Navigate to the Compile tab. Find "Generate XML documentation file" at the bottom of the window, and make sure it is checked. By default this setting is on. It generates an XML file using the same name and path as the assembly.

I don't have enough reputation to add a comment on the answer from pomber so I'm posting another answer. Using pomber's approach I kept receiving a "400 Bad Request" response from an API I was POSTing my JSON request to (Visual Studio 2017, .NET 4.6.2). Eventually the problem was traced to the "Content-Type" header produced by StringContent() being incorrect (see https://github.com/dotnet/corefx/issues/7864).

tl;dr

Use pomber's answer with an extra line to correctly set the header on the request:

var content = new StringContent(jsonObject.ToString(), Encoding.UTF8, "application/json");
content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
var result = client.PostAsync(url, content).Result;

As usual, by pressing F2 on the package name, you can rename or change the package name, and also by right-clicking and then select Rename option, you can change or rename the package name.

When you press F2, it will show you the dialog box as:

In this dialog, don't forget to check the "Update references" checkbox because by making "check" to this check-box, it will make changes to all the references of the package which are referred by other components of project.

Remove the \bin, and also remove the ; at the end. After restart the cmd and run.

To start the port correctly in your desired port use:

npm start -- --port 8000

because of two way binding, To prevent error of:

ExpressionChangedAfterItHasBeenCheckedError: Expression has changed after it was 
checked.

you can call a function to change model like this:

<input [ngModel]="item.value" 
  (ngModelChange)="getNewValue($event)" name="inputField" type="text" />


import { UseMyPipeToFormatThatValuePipe } from './path';

constructor({
    private UseMyPipeToFormatThatValue: UseMyPipeToFormatThatValuePipe,
})

getNewValue(ev: any): any {
    item.value= this.useMyPipeToFormatThatValue.transform(ev);
}

it'll be good if there is a better solution to prevent this error.

Note the following is functionally different to Gordon Linoff's answer. His answer assumes that you want to use email2 if email is NULL. Mine assumes you want to use email2 if email is an empty-string. The correct answer will depend on your database (or you could perform a NULL check and an empty-string check - it all depends on what is appropriate for your database design).

SELECT  `id` ,  `naam` 
FROM  `klanten` 
WHERE `email` LIKE  '%[email protected]%'
OR (LENGTH(email) = 0 AND `email2` LIKE  '%[email protected]%')

DateTimeFormatter has in-built formats that can directly be used to parse a character sequence. It is case Sensitive, Nov will work however nov and NOV wont work:

DateTimeFormatter pattern = DateTimeFormatter.ofPattern("yyyy-MMM-dd");

try {
    LocalDate datetime = LocalDate.parse(oldDate, pattern);
    System.out.println(datetime); 
} catch (DateTimeParseException e) {
    // DateTimeParseException - Text '2019-nov-12' could not be parsed at index 5
    // Exception handling message/mechanism/logging as per company standard
}

DateTimeFormatterBuilder provides custom way to create a formatter. It is Case Insensitive, Nov , nov and NOV will be treated as same.

DateTimeFormatter f = new DateTimeFormatterBuilder().parseCaseInsensitive()
        .append(DateTimeFormatter.ofPattern("yyyy-MMM-dd")).toFormatter();
try {
    LocalDate datetime = LocalDate.parse(oldDate, f);
    System.out.println(datetime); // 2019-11-12
} catch (DateTimeParseException e) {
     // Exception handling message/mechanism/logging as per company standard
}

You simply have to do:

INSERT INTO def (catid, title, page, publish) 
SELECT catid, title, 'page','yes' from `abc`

The reason you're getting the error is that you have a Unix-style path to the python executable, when you're running Windows. Change /usr/bin/python3 to C:/Python32/python.exe (make sure you use the forward slashes / and not Windows-style back slashes \). Once you make this change, you should be all set.

Also, you need to change the single quotes ' to double quotes " like so:

{
    "cmd": ["c:/Python32/python.exe", "-u", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

The .sublime-build file needs to be valid JSON, which requires strings be wrapped in double quotes, not single.

Did you try to chomp the $str1 and $str2?

I found a similar issue with using (another) $str1 eq 'Y' and it only went away when I first did:

chomp($str1);
if ($str1 eq 'Y') {
....
}

works after that.

Hope that helps.

Change the function that you get one single Result=[array, listp, freep]. So there is only one result to be displayed

Just a slight addition to the above solution if you are having problem with downloaded file's name...

Response.AddHeader("Content-Disposition", "attachment; filename=\"" + file.Name + "\"");

This will return the exact file name even if it contains spaces or other characters.

there is another way, if you are using a container like Tomcat :

String textPath = "http://localhost:8080/NameOfWebapp/resources/images/file.txt";

Or, if you are doing a split - join:

GROUP_CONCAT(split(thing, " "), '----') AS thing_name,

You may want to inclue WITHIN RECORD, like this:

GROUP_CONCAT(split(thing, " "), '----') WITHIN RECORD AS thing_name,

First import NumberFormat. Then add this:

NumberFormat currencyFormatter = NumberFormat.getCurrencyInstance();

This will give you two decimal places and put a dollar sign if it's dealing with currency.

import java.text.NumberFormat;

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) 
    {
    int hoursWorked = 80;
    double hourlyPay = 15.52;

    double grossPay = hoursWorked * hourlyPay;
    NumberFormat currencyFormatter = NumberFormat.getCurrencyInstance();

    System.out.println("Your gross pay is " + currencyFormatter.format(grossPay));
    }

}

For Windows 7 with NIO 2:

    Path file = Paths.get("c:/touch.txt");
    AclFileAttributeView aclAttr = Files.getFileAttributeView(file, AclFileAttributeView.class);
    System.out.println(aclAttr.getOwner());
    for (AclEntry aclEntry : aclAttr.getAcl()) {
        System.out.println(aclEntry);
    }
    System.out.println();
    
    UserPrincipalLookupService upls = file.getFileSystem().getUserPrincipalLookupService();
    UserPrincipal user = upls.lookupPrincipalByName(System.getProperty("user.name"));
    AclEntry.Builder builder = AclEntry.newBuilder();       
    builder.setPermissions( EnumSet.of(AclEntryPermission.READ_DATA, AclEntryPermission.EXECUTE, 
            AclEntryPermission.READ_ACL, AclEntryPermission.READ_ATTRIBUTES, AclEntryPermission.READ_NAMED_ATTRS,
            AclEntryPermission.WRITE_ACL, AclEntryPermission.DELETE
    ));
    builder.setPrincipal(user);
    builder.setType(AclEntryType.ALLOW);
    aclAttr.setAcl(Collections.singletonList(builder.build()));
}

I see a couple of issues.

First:

ser.read() is only going to return 1 byte at a time.

If you specify a count

ser.read(5)

it will read 5 bytes (less if timeout occurrs before 5 bytes arrive.)

If you know that your input is always properly terminated with EOL characters, better way is to use

ser.readline()

That will continue to read characters until an EOL is received.

Second:

Even if you get ser.read() or ser.readline() to return multiple bytes, since you are iterating over the return value, you will still be handling it one byte at a time.

Get rid of the

for line in ser.read():

and just say:

line = ser.readline()

Python 2 will automatically set the type based on the size of the value. A guide of max values can be found below.

The Max value of the default Int in Python 2 is 65535, anything above that will be a long

For example:

>> print type(65535)
<type 'int'>
>>> print type(65536*65536)
<type 'long'>

In Python 3 the long datatype has been removed and all integer values are handled by the Int class. The default size of Int will depend on your CPU architecture.

For example:

• 32 bit systems the default datatype for integers will be 'Int32'
• 64 bit systems the default datatype for integers will be 'Int64'

The min/max values of each type can be found below:

• Int8: [-128,127]
• Int16: [-32768,32767]
• Int32: [-2147483648,2147483647]
• Int64: [-9223372036854775808,9223372036854775807]
• Int128: [-170141183460469231731687303715884105728,170141183460469231731687303715884105727]
• UInt8: [0,255]
• UInt16: [0,65535]
• UInt32: [0,4294967295]
• UInt64: [0,18446744073709551615]
• UInt128: [0,340282366920938463463374607431768211455]

If the size of your Int exceeds the limits mentioned above, python will automatically change it's type and allocate more memory to handle this increase in min/max values. Where in Python 2, it would convert into 'long', it now just converts into the next size of Int.

Example: If you are using a 32 bit operating system, your max value of an Int will be 2147483647 by default. If a value of 2147483648 or more is assigned, the type will be changed to Int64.

There are different ways to check the size of the int and it's memory allocation. Note: In Python 3, using the built-in type() method will always return <class 'int'> no matter what size Int you are using.

$scope.removeItem = function() {

this works for me!

Using morelinq you can use DistinctBy:

myList.DistinctBy(x => x.id);

Otherwise, you can use a group:

myList.GroupBy(x => x.id)
      .Select(g => g.First());

On *nixes, it's in ~/.gitconfig. Is there a corresponding file in your home?

On Windows you can type in git bash

notepad ~/.gitconfig

This is an direct excerpt from the excellent book 'Thinking in Java' by Bruce Eckel.

[..] Should you use an interface or an abstract class?

Well, an interface gives you the benefits of an abstract class and the benefits of an interface, so if it’s possible to create your base class without any method definitions or member variables you should always prefer interfaces to abstract classes.

In fact, if you know something is going to be a base class, your first choice should be to make it an interface, and only if you’re forced to have method definitions or member variables should you change to an abstract class.

For situations when I need to replace or match(find) something against string I prefer using regular expressions.

Since, the regular expressions are not fully supported in T-SQL you can implement them using CLR functions. Furthermore, you do not need any C# or CLR knowledge at all as all you need is already available in the MSDN String Utility Functions Sample.

In your case, the solution using regular expressions is:

SELECT [dbo].[RegexReplace] ([MyColumn], '(;.*)', '')
FROM [dbo].[MyTable]

But implementing such function in your database is going to help you solving more complex issues at all.

The example below shows how to deploy only the [dbo].[RegexReplace] function, but I will recommend to you to deploy the whole String Utility class.

1. Enabling CLR Integration. Execute the following Transact-SQL commands:

   sp_configure 'clr enabled', 1
   GO
   RECONFIGURE
   GO  
   

2. Bulding the code (or creating the .dll). Generraly, you can do this using the Visual Studio or .NET Framework command prompt (as it is shown in the article), but I prefer to use visual studio.

   • create new class library project:

     

   • copy and paste the following code in the Class1.cs file:

     using System;
     using System.IO;
     using System.Data.SqlTypes;
     using System.Text.RegularExpressions;
     using Microsoft.SqlServer.Server;
     
     public sealed class RegularExpression
     {
         public static string Replace(SqlString sqlInput, SqlString sqlPattern, SqlString sqlReplacement)
         {
             string input = (sqlInput.IsNull) ? string.Empty : sqlInput.Value;
             string pattern = (sqlPattern.IsNull) ? string.Empty : sqlPattern.Value;
             string replacement = (sqlReplacement.IsNull) ? string.Empty : sqlReplacement.Value;
             return Regex.Replace(input, pattern, replacement);
         }
     }
     

   • build the solution and get the path to the created .dll file:

     

   • replace the path to the .dll file in the following T-SQL statements and execute them:

     IF OBJECT_ID(N'RegexReplace', N'FS') is not null
     DROP Function RegexReplace;
     GO
     
     IF EXISTS (SELECT * FROM sys.assemblies WHERE [name] = 'StringUtils')
     DROP ASSEMBLY StringUtils;
     GO
     
     DECLARE @SamplePath nvarchar(1024)
     -- You will need to modify the value of the this variable if you have installed the sample someplace other than the default location.
     Set @SamplePath = 'C:\Users\gotqn\Desktop\StringUtils\StringUtils\StringUtils\bin\Debug\'
     CREATE ASSEMBLY [StringUtils] 
     FROM @SamplePath + 'StringUtils.dll'
     WITH permission_set = Safe;
     GO
     
     
     CREATE FUNCTION [RegexReplace] (@input nvarchar(max), @pattern nvarchar(max), @replacement nvarchar(max))
     RETURNS nvarchar(max)
     AS EXTERNAL NAME [StringUtils].[RegularExpression].[Replace]
     GO
     

   • That's it. Test your function:

     declare @MyTable table ([id] int primary key clustered, MyText varchar(100))
     insert into @MyTable ([id], MyText)
     select 1, 'some text; some more text'
     union all select 2, 'text again; even more text'
     union all select 3, 'text without a semicolon'
     union all select 4, null -- test NULLs
     union all select 5, '' -- test empty string
     union all select 6, 'test 3 semicolons; second part; third part'
     union all select 7, ';' -- test semicolon by itself    
     
     SELECT [dbo].[RegexReplace] ([MyText], '(;.*)', '')
     FROM @MyTable
     
     select * from @MyTable
     

To make this easier to use, I wrote a generic extension:

public static string ToDescription<TEnum>(this TEnum EnumValue) where TEnum : struct
{
    return Enumerations.GetEnumDescription((Enum)(object)((TEnum)EnumValue));
}

now I can write:

        MyEnum my = MyEnum.HereIsAnother;
        string description = my.ToDescription();
        System.Diagnostics.Debug.Print(description);

Note: replace "Enumerations" above with your class name

It means that the callback function you passed to this.dataStore.data.find should return a boolean and have 3 parameters, two of which can be optional:

• value: Conversations
• index: number
• obj: Conversation[]

However, your callback function does not return anything (returns void). You should pass a callback function with the correct return value:

this.dataStore.data.find((element, index, obj) => {
    // ...

    return true; // or false
});

or:

this.dataStore.data.find(element => {
    // ...

    return true; // or false
});

Reason why it's this way: the function you pass to the find method is called a predicate. The predicate here defines a boolean outcome based on conditions defined in the function itself, so that the find method can determine which value to find.

In practice, this means that the predicate is called for each item in data, and the first item in data for which your predicate returns true is the value returned by find.

This solution is applicable even when you have different size of array being merged. Also, even if the keys on which match is happening has a different name.

const arr1 = [
  { id: "abdc4051", date: "2017-01-24" }, 
  { id: "abdc4052", date: "2017-01-22" },
  { id: "abdc4053", date: "2017-01-22" }
];
const arr2 = [
  { nameId: "abdc4051", name: "ab" },
  { nameId: "abdc4052", name: "abc" }
];

Now to merge these use a Map as follows:

const map = new Map();
arr1.forEach(item => map.set(item.id, item));
arr2.forEach(item => map.set(item.nameId, {...map.get(item.nameId), ...item}));
const mergedArr = Array.from(map.values());

This should result in:

[
  {
    "id": "abdc4051",
    "date": "2017-01-24",
    "nameId": "abdc4051",
    "name": "ab"
  },
  {
    "id": "abdc4052",
    "date": "2017-01-22",
    "nameId": "abdc4052",
    "name": "abc"
  },
  {
    "id": "abdc4053",
    "date": "2017-01-22"
  }
]

@p4bloch if you want to capture results from a series of capture parentheses, then you need to use the rangeAtIndex(index) method of NSTextCheckingResult, instead of range. Here's @MartinR 's method for Swift2 from above, adapted for capture parentheses. In the array that is returned, the first result [0] is the entire capture, and then individual capture groups begin from [1]. I commented out the map operation (so it's easier to see what I changed) and replaced it with nested loops.

func matches(for regex: String!, in text: String!) -> [String] {

    do {
        let regex = try NSRegularExpression(pattern: regex, options: [])
        let nsString = text as NSString
        let results = regex.matchesInString(text, options: [], range: NSMakeRange(0, nsString.length))
        var match = [String]()
        for result in results {
            for i in 0..<result.numberOfRanges {
                match.append(nsString.substringWithRange( result.rangeAtIndex(i) ))
            }
        }
        return match
        //return results.map { nsString.substringWithRange( $0.range )} //rangeAtIndex(0)
    } catch let error as NSError {
        print("invalid regex: \(error.localizedDescription)")
        return []
    }
}

An example use case might be, say you want to split a string of title year eg "Finding Dory 2016" you could do this:

print ( matches(for: "^(.+)\\s(\\d{4})" , in: "Finding Dory 2016"))
// ["Finding Dory 2016", "Finding Dory", "2016"]

You can't "open" a directory using the open function. This function is meant to be used to open files.

Here, what you want to do is open the file that's in the directory. The first thing you must do is compute this file's path. The os.path.join function will let you do that by joining parts of the path (the directory and the file name):

fpath = os.path.join(direct, "5_1.txt")

You can then open the file:

f = open(fpath)

And read its content:

content = f.read()

Additionally, I believe that on Windows, using open on a directory does return a PermissionDenied exception, although that's not really the case.

Don't include bin folder while coping the path for Java_home.

I'd probably use the solution in @fixagon's answer.

However, while the Decimal struct doesn't have a method to get the number of decimals, you could call Decimal.GetBits to extract the binary representation, then use the integer value and scale to compute the number of decimals.

This would probably be faster than formatting as a string, though you'd have to be processing an awful lot of decimals to notice the difference.

I'll leave the implementation as an exercise.

While I would be tempted to blame my issues - I'm getting the same error with my query, which is much, much bigger and involves a lot of loops - on the network, I think this is not the case.

Unfortunately it's not that simple. Query runs for 3+ hours before getting that error and apparently it crashes at the same time if it's just a query in SSMS and a job on SQL Server (did not look into details of that yet, so not sure if it's the same error; definitely same spot, though).

So just in case someone comes here with similar problem, this thread: https://www.sqlservercentral.com/Forums/569962/The-semaphore-timeout-period-has-expired

suggest that it may equally well be a hardware issue or actual timeout.

My loops aren't even (they depend on sales level in given month) in terms of time required for each, so good month takes about 20 mins to calculate (query looks at 4 years).

That way it's entirely possible I need to optimise my query. I would even say it's likely, as some changes I did included new tables, which are heaps... So another round of indexing my data before tearing into VM config and hardware tests.

Being aware that this is old question: I'm on SQL Server 2012 SE, SSMS is 2018 Beta and VM the SQL Server runs on has exclusive use of 132GB of RAM (30% total), 8 cores, and 2TB of SSD SAN.

Here's a solution to your problem using dplyr's filter function.

Although you can pass your data frame as the first argument to any dplyr function, I've used its %>% operator, which pipes your data frame to one or more dplyr functions (just filter in this case).

Once you are somewhat familiar with dplyr, the cheat sheet is very handy.

> print(df <- data.frame(sub=rep(1:3, each=4), day=1:4))
   sub day
1    1   1
2    1   2
3    1   3
4    1   4
5    2   1
6    2   2
7    2   3
8    2   4
9    3   1
10   3   2
11   3   3
12   3   4
> print(df <- df %>% filter(!((sub==1 & day==2) | (sub==3 & day==4))))
   sub day
1    1   1
2    1   3
3    1   4
4    2   1
5    2   2
6    2   3
7    2   4
8    3   1
9    3   2
10   3   3

A better way to do it is to delete the cache and rebuild it. In this way, if you install it again for other virtualenv, it will use the cache instead of building every time when you install it.

For example, when you install it, it will say it uses cached wheel,

Processing <some_prefix>/Library/Caches/pip/wheels/d0/c4/e4/e49fd07bca8dda00dd6b4bbc606aa05a25aacb00d45747a47a/horovod-0.19.3-cp37-cp37m-macosx_10_9_x86_64.wh

Just delete that one and restart your install.

Check out the .read() method of the File object:

http://docs.python.org/2/tutorial/inputoutput.html#methods-of-file-objects

You could do something like:

concat = ""
for file in files:
    concat += open(file).read()

or a more 'elegant' python-way:

concat = ''.join([open(f).read() for f in files])

which, according to this article: http://www.skymind.com/~ocrow/python_string/ would also be the fastest.

Since C# 7, you can use Tuples...

int[] nums = { 1, 2, 3, 4 };
string[] words = { "one", "two", "three", "four" };

foreach (var tuple in nums.Zip(words, (x, y) => (x, y)))
{
    Console.WriteLine($"{tuple.Item1}: {tuple.Item2}");
}

// or...
foreach (var tuple in nums.Zip(words, (x, y) => (Num: x, Word: y)))
{
    Console.WriteLine($"{tuple.Num}: {tuple.Word}");
}

Here is a really simple solution using SASS/SCSS and a math formula style:

/* frame circle */
.container {
    position: relative;
    border-radius: 50%;
    background-color: white;
    overflow: hidden;
    width: 400px;
    height: 400px; }

/* circle sectors */
.menu-frame-sector {
    position: absolute;
    width: 50%;
    height: 50%;
    z-index: 10000;
    transform-origin: 100% 100%;
  }

$sector_count: 8;
$sector_width: 360deg / $sector_count;

.sec0 {
    transform: rotate(0 * $sector_width) skew($sector_width);
    background-color: red; }
.sec1 {
    transform: rotate(1 * $sector_width) skew($sector_width);
    background-color: blue; }
.sec2 {
    transform: rotate(2 * $sector_width) skew($sector_width);
    background-color: red; }
.sec3 {
    transform: rotate(3 * $sector_width) skew($sector_width);
    background-color: blue; }
.sec4 {
    transform: rotate(4 * $sector_width) skew($sector_width);
    background-color: red; }
.sec5 {
    transform: rotate(5 * $sector_width) skew($sector_width);
    background-color: blue; }
.sec6 {
    transform: rotate(6 * $sector_width) skew($sector_width);
    background-color: red; }
.sec7 {
    transform: rotate(7 * $sector_width) skew($sector_width);
    background-color: blue; }

To conclude, I strongly suggest you to understand transform-origin, rotate() and skew():

int myInt = 65;

char myChar = (char)myInt;  // myChar should now be the letter A

char[20] myString = {0}; // make an empty string.

myString[0] = myChar;
myString[1] = myChar; // Now myString is "AA"

This should all be found in any intro to C book, or by some basic online searching.

I would simply do this, which literally follows what your desired logic was:

df.groupby(['org']).mean().groupby(['cluster']).mean()

by default -

you can also log in to sql express using server name as:

./SQLEXPRESS

or log in to sql server simply as

.

You've already done it correctly by using a DateTime parameter with the value from the DateTime, so it should already work. Forget about ToString() - since that isn't used here.

If there is a difference, it is most likely to do with different precision between the two environments; maybe choose a rounding (seconds, maybe?) and use that. Also keep in mind UTC/local/unknown (the DB has no concept of the "kind" of date; .NET does).

I have a table and the date-times in it are in the format: 2011-07-01 15:17:33.357

Note that datetimes in the database aren't in any such format; that is just your query-client showing you white lies. It is stored as a number (and even that is an implementation detail), because humans have this odd tendency not to realise that the date you've shown is the same as 40723.6371916281. Stupid humans. By treating it simply as a "datetime" throughout, you shouldn't get any problems.

Try pm2 to make your application run forever.

npm install -g pm2

If you want to change inputs in an iframe then submit the form from that iframe, do this

...
var el = document.getElementById('targetFrame');

var doc, frame_win = getIframeWindow(el); // getIframeWindow is defined below

if (frame_win) {
  doc = (window.contentDocument || window.document);
}

if (doc) {
  doc.forms[0].someInputName.value = someValue;
  ...
  doc.forms[0].submit();
}
...

Normally, you can only do this if the page in the iframe is from the same origin, but you can start Chrome in a debug mode to disregard the same origin policy and test this on any page.

function getIframeWindow(iframe_object) {
  var doc;

  if (iframe_object.contentWindow) {
    return iframe_object.contentWindow;
  }

  if (iframe_object.window) {
    return iframe_object.window;
  } 

  if (!doc && iframe_object.contentDocument) {
    doc = iframe_object.contentDocument;
  } 

  if (!doc && iframe_object.document) {
    doc = iframe_object.document;
  }

  if (doc && doc.defaultView) {
   return doc.defaultView;
  }

  if (doc && doc.parentWindow) {
    return doc.parentWindow;
  }

  return undefined;
}

Because System.exit() is just another method to the compiler. It doesn't read ahead and figure out that the whole program will quit at that point (the JVM quits). Your OS or shell can read the integer that is passed back in the System.exit() method. It is standard for 0 to mean "program quit and everything went OK" and any other value to notify an error occurred. It is up to the developer to document these return values for any users.

return on the other hand is a reserved key word that the compiler knows well. return returns a value and ends the current function's run moving back up the stack to the function that invoked it (if any). In your code above it returns void as you have not supplied anything to return.

I've seen many answers but they seem confusing to me. Can't we just simply use Type Casting.

For ex:-

int s;
char i= '2';
s = (int) i;

just re-installed mongo and it worked. No collections lost. Easiest solution atleast for me

When you write a lambda expression, the argument list to the left of -> can be either a parenthesized argument list (possibly empty), or a single identifier without any parentheses. But in the second form, the identifier cannot be declared with a type name. Thus:

this.stops.stream().filter(Stop s-> s.getStation().getName().equals(name));

is incorrect syntax; but

this.stops.stream().filter((Stop s)-> s.getStation().getName().equals(name));

is correct. Or:

this.stops.stream().filter(s -> s.getStation().getName().equals(name));

is also correct if the compiler has enough information to figure out the types.

use colspan for do this

 <td colspan="3">PUR mix up column</td>

export class Car {
  id: number;
  make: string;
  model: string;
  color: string;
  year: Date;

  constructor(car) {
      {
        this.id = car.id;
        this.make = car.make || '';
        this.model = car.model || '';
        this.color = car.color || '';
        this.year = new Date(car.year).getYear();
      }
  }
}

The || can become super useful for very complex data objects to default data that doesn't exist.

. .

In your component.ts or service.ts file you can deserialize response data into the model:

// Import the car model
import { Car } from './car.model.ts';

// If single object
car = new Car(someObject);

// If array of cars
cars = someDataToDeserialize.map(c => new Car(c));

hope you are doing well.when I started work with Android Fragments then I was also having the same problem then I read about 1- How to switch fragment with other. 2- How to add fragment if Fragment container does not have any fragment.

then after some R&D, I created a function which helps me in many Projects till now and I am still using this simple function.

public void switchFragment(BaseFragment baseFragment) {
    try {
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        ft.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right);
        if (getSupportFragmentManager().findFragmentById(R.id.home_frame) == null) {
            ft.add(R.id.home_frame, baseFragment);
        } else {
            ft.replace(R.id.home_frame, baseFragment);
        }
        ft.addToBackStack(null);
        ft.commit();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

enjoy your code time :)

To expound on Numenor's answer you can do something like, Format(Now(),"HH:mm:ss") using these custom date/time formating options

For everyone who is tempted to downvote this answer please be aware that the question was originally tagged VB and vbscript hence my answer, the VB tag was edited out leaving only the vbscript tag. The OP accepted this answer which I take to mean that it gave him the information that he needed.

To detect both positive and negative peaks, PeakDetect is helpful.

from peakdetect import peakdetect

peaks = peakdetect(data, lookahead=20) 
# Lookahead is the distance to look ahead from a peak to determine if it is the actual peak. 
# Change lookahead as necessary 
higherPeaks = np.array(peaks[0])
lowerPeaks = np.array(peaks[1])
plt.plot(data)
plt.plot(higherPeaks[:,0], higherPeaks[:,1], 'ro')
plt.plot(lowerPeaks[:,0], lowerPeaks[:,1], 'ko')

I did some benchmarking for speed on these answers and was surprised to see percent in the scales package so touted, given its sluggishness. I imagine the advantage is its automatic detector for for proper formatting, but if you know what your data looks like it seems clear to be avoided.

Here are the results from trying to format a list of 100,000 percentages in (0,1) to a percentage in 2 digits:

library(microbenchmark)
x = runif(1e5)
microbenchmark(times = 100L, andrie1(), andrie2(), richie(), krlmlr())
# Unit: milliseconds
#   expr       min        lq      mean    median        uq       max
# 1 andrie1()  91.08811  95.51952  99.54368  97.39548 102.75665 126.54918 #paste(round())
# 2 andrie2()  43.75678  45.56284  49.20919  47.42042  51.23483  69.10444 #sprintf()
# 3  richie()  79.35606  82.30379  87.29905  84.47743  90.38425 112.22889 #paste(formatC())
# 4  krlmlr() 243.19699 267.74435 304.16202 280.28878 311.41978 534.55904 #scales::percent()

So sprintf emerges as a clear winner when we want to add a percent sign. On the other hand, if we only want to multiply the number and round (go from proportion to percent without "%", then round() is fastest:

# Unit: milliseconds
#        expr      min        lq      mean    median        uq       max
# 1 andrie1()  4.43576  4.514349  4.583014  4.547911  4.640199  4.939159 # round()
# 2 andrie2() 42.26545 42.462963 43.229595 42.960719 43.642912 47.344517 # sprintf()
# 3  richie() 64.99420 65.872592 67.480730 66.731730 67.950658 96.722691 # formatC()

Ok so I took Joshoun code and made it generic. I am not sure if I should implement singleton pattern on SynchronousPost class. Maybe someone more knowledgeble can help.

Implementation

FileCategory x = new FileCategory { CategoryName = "Some Bs"};
SynchronousPost<FileCategory>test= new SynchronousPost<FileCategory>();
test.PostEntity(x, "/api/ApiFileCategories"); 

Generic Class here. You can pass any type

 public class SynchronousPost<T>where T :class
    {
        public SynchronousPost()
        {
            Client = new WebClient { UseDefaultCredentials = true };
        }

        public void PostEntity(T PostThis,string ApiControllerName)//The ApiController name should be "/api/MyName/"
        {
            //this just determines the root url. 
            Client.BaseAddress = string.Format(
         (
            System.Web.HttpContext.Current.Request.Url.Port != 80) ? "{0}://{1}:{2}" : "{0}://{1}",
            System.Web.HttpContext.Current.Request.Url.Scheme,
            System.Web.HttpContext.Current.Request.Url.Host,
            System.Web.HttpContext.Current.Request.Url.Port
           );
            Client.Headers.Add(HttpRequestHeader.ContentType, "application/json;charset=utf-8");
            Client.UploadData(
                                 ApiControllerName, "Post", 
                                 Encoding.UTF8.GetBytes
                                 (
                                    JsonConvert.SerializeObject(PostThis)
                                 )
                             );  
        }
        private WebClient Client  { get; set; }
    }

My Api classs looks like this, if you are curious

public class ApiFileCategoriesController : ApiBaseController
{
    public ApiFileCategoriesController(IMshIntranetUnitOfWork unitOfWork)
    {
        UnitOfWork = unitOfWork;
    }

    public IEnumerable<FileCategory> GetFiles()
    {
        return UnitOfWork.FileCategories.GetAll().OrderBy(x=>x.CategoryName);
    }
    public FileCategory GetFile(int id)
    {
        return UnitOfWork.FileCategories.GetById(id);
    }
    //Post api/ApileFileCategories

    public HttpResponseMessage Post(FileCategory fileCategory)
    {
        UnitOfWork.FileCategories.Add(fileCategory);
        UnitOfWork.Commit(); 
        return new HttpResponseMessage();
    }
}

I am using ninject, and repo pattern with unit of work. Anyways, the generic class above really helps.

To find out if it's visible with plain JavaScript, check whether the display property is 'none' (don't check for 'block', it could also be blank or 'inline' and still be visible):

var isVisible = (elt.style.display != "none");

If you are using jQuery, you can use this instead:

var isVisible = $elt.is(":visible");

public interface StudentDAO extends JpaRepository<StudentEntity, Integer> {
    public List<StudentEntity> findAllByOrderByIdAsc();
}

The code above should work. I'm using something similar:

public List<Pilot> findTop10ByOrderByLevelDesc();

It returns 10 rows with the highest level.

IMPORTANT: Since I've been told that it's easy to miss the key point of this answer, here's a little clarification:

findAllByOrderByIdAsc(); // don't miss "by"
       ^

Java 1.5 introduced the Scanner class for handling input from file and streams.

It is used for getting integers from a file and would look something like this:

List<Integer> integers = new ArrayList<Integer>();
Scanner fileScanner = new Scanner(new File("c:\\file.txt"));
while (fileScanner.hasNextInt()){
   integers.add(fileScanner.nextInt());
}

Check the API though. There are many more options for dealing with different types of input sources, differing delimiters, and differing data types.

There's a rather crude way of doing this, but be careful because first, this relies on python interpreter process identifying themselves as python, and second, it has the concomitant effect of also killing any other processes identified by that name.

In short, you can kill all python interpreters by typing this into your shell (make sure you read the caveats above!):

ps aux | grep python | grep -v "grep python" | awk '{print $2}' | xargs kill -9

To break this down, this is how it works. The first bit, ps aux | grep python | grep -v "grep python", gets the list of all processes calling themselves python, with the grep -v making sure that the grep command you just ran isn't also included in the output. Next, we use awk to get the second column of the output, which has the process ID's. Finally, these processes are all (rather unceremoniously) killed by supplying each of them with kill -9.

Another possibility is to use an absolute positioning oriented to the right:

<input type="button" value="Click Me" style="position: absolute; right: 0;">

Here's an example: https://jsfiddle.net/a2Ld1xse/

This solution has its downsides, but there are use cases where it's very useful.

In spark/scala, it's pretty easy to filter with varargs.

val d = spark.read...//data contains column named matid
val ids = Seq("BNBEL0608AH", "BNBEL00608H")
val filtered = d.filter($"matid".isin(ids:_*))

<input type="number" step="any">

This worked for me and i think is the easiest way to make the input field accept any decimal number irrespective of how long the decimal part is. Step attribute actually shows the input field how many decimal points should be accepted. E.g, step="0.01" will accept only two decimal points.

Another scenario that can cause this exception is with DataBinding, that is when you use something like this in your layout

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <data>

        <variable
            name="model"
            type="point.to.your.model"/>
    </data>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="@{model.someIntegerVariable}"/>

</layout>

Notice that the variable I'm using is an Integer and I'm assigning it to the text field of the TextView. Since the TextView already has a method with signature of setText(int) it will use this method instead of using the setText(String) and cast the value. Thus the TextView thinks of your input number as a resource value which obviously is not valid.

Solution is to cast your int value to string like this

android:text="@{String.valueOf(model.someIntegerVariable)}"

In MySQL you can do this:

SELECT `PRIMARY_KEY`, rand() FROM table ORDER BY rand() LIMIT 5000;

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/

Here is a solution that also takes in account if you are using Ajax requests.

using System;
using System.Web.Mvc;
using System.Web.Routing;

namespace YourNamespace{        
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
    public class AuthorizeCustom : ActionFilterAttribute {
        public override void OnActionExecuting(ActionExecutingContext context) {
            if (YourAuthorizationCheckGoesHere) {               
                string area = "";// leave empty if not using area's
                string controller = "ControllerName";
                string action = "ActionName";
                var urlHelper = new UrlHelper(context.RequestContext);                  
                if (context.HttpContext.Request.IsAjaxRequest()){ // Check if Ajax
                    if(area == string.Empty)
                        context.HttpContext.Response.Write($"<script>window.location.reload('{urlHelper.Content(System.IO.Path.Combine(controller, action))}');</script>");
                    else
                        context.HttpContext.Response.Write($"<script>window.location.reload('{urlHelper.Content(System.IO.Path.Combine(area, controller, action))}');</script>");
                } else   // Non Ajax Request                      
                    context.Result = new RedirectToRouteResult(new RouteValueDictionary( new{ area, controller, action }));             
            }
            base.OnActionExecuting(context);
        }
    }
}

If you are using the default cursor, a MySQLdb.cursors.Cursor, the entire result set will be stored on the client side (i.e. in a Python list) by the time the cursor.execute() is completed.

Therefore, even if you use

for row in cursor:

you will not be getting any reduction in memory footprint. The entire result set has already been stored in a list (See self._rows in MySQLdb/cursors.py).

However, if you use an SSCursor or SSDictCursor:

import MySQLdb
import MySQLdb.cursors as cursors

conn = MySQLdb.connect(..., cursorclass=cursors.SSCursor)

then the result set is stored in the server, mysqld. Now you can write

cursor = conn.cursor()
cursor.execute('SELECT * FROM HUGETABLE')
for row in cursor:
    print(row)

and the rows will be fetched one-by-one from the server, thus not requiring Python to build a huge list of tuples first, and thus saving on memory.

Otherwise, as others have already stated, cursor.fetchall() and list(cursor) are essentially the same.

This is how I run my commands. This code has everything you need pretty much

from subprocess import Popen, PIPE
cmd = "ls -l ~/"
p = Popen(cmd , shell=True, stdout=PIPE, stderr=PIPE)
out, err = p.communicate()
print "Return code: ", p.returncode
print out.rstrip(), err.rstrip()

You can use the CONCAT function to do that:

UPDATE tbl SET col=CONCAT('test',col);

If you want to get cleverer and only update columns which don't already have test prepended, try

UPDATE tbl SET col=CONCAT('test',col)
WHERE col NOT LIKE 'test%';

I wrote a simple Angular Directive that's been working well for us.

Here's a demo: http://jsbin.com/tesido/edit?html,js,output

Directive (for Bootstrap 3):

// registers native Twitter Bootstrap 3 tooltips
app.directive('bootstrapTooltip', function() {
  return function(scope, element, attrs) {
    attrs.$observe('title',function(title){
      // Destroy any existing tooltips (otherwise new ones won't get initialized)
      element.tooltip('destroy');
      // Only initialize the tooltip if there's text (prevents empty tooltips)
      if (jQuery.trim(title)) element.tooltip();
    })
    element.on('$destroy', function() {
      element.tooltip('destroy');
      delete attrs.$$observers['title'];
    });
  }
});

Note: If you're using Bootstrap 4, on lines 6 & 11 above you'll need to replace tooltip('destroy') with tooltip('dispose') (Thanks to user1191559 for this upadate)

Simply add bootstrap-tooltip as an attribute to any element with a title. Angular will monitor for changes to the title but otherwise pass the tooltip handling over to Bootstrap.

This also allows you to use any of the native Bootstrap Tooltip Options as data- attributes in the normal Bootstrap way.

Markup:

<div bootstrap-tooltip data-placement="left" title="Tooltip on left">
        Tooltip on left
</div>

Clearly this doesn't have all the elaborate bindings & advanced integration that AngularStrap and UI Bootstrap offer, but it's a good solution if you're already using Bootstrap's JS in your Angular app and you just need a basic tooltip bridge across your entire app without modifying controllers or managing mouse events.

I fixed this problem by editing config.inc.php file which is in phpmyadmin folder: specifically changed $cfg['Servers'][$i]['host'] = 'localhost' to $cfg['Servers'][$i]['host'] = '127.0.0.1'

If you run npm config edit, you'll get an editor showing the current configuration, and also a list of options and their default values.

But I don't think there's a 'reset' command.

1. Select all cells by left-top corner
2. Choose [Home] >> [Conditional Formatting] >> [New Rule]
3. Choose [Format only cells that contain]
4. In [Format only cells with:], choose "Errors"
5. Choose proper formats in [Format..] button

There are two approaches, you can code in JScript or VBScript which do have the construct or you can fudge it in your code.

Using JScript you'd use the following type of construct:

<script language="jscript" runat="server">
try  {
    tryStatements
}
catch(exception) {
    catchStatements
}
finally {
    finallyStatements
}
</script>

In your ASP code you fudge it by using on error resume next at the point you'd have a try and checking err.Number at the point of a catch like:

<%
' Turn off error Handling
On Error Resume Next


'Code here that you want to catch errors from

' Error Handler
If Err.Number <> 0 Then
   ' Error Occurred - Trap it
   On Error Goto 0 ' Turn error handling back on for errors in your handling block
   ' Code to cope with the error here
End If
On Error Goto 0 ' Reset error handling.

%>

This worked nicely

OutputStream output = new OutputStream() {
    private StringBuilder string = new StringBuilder();

    @Override
    public void write(int b) throws IOException {
        this.string.append((char) b );
    }

    //Netbeans IDE automatically overrides this toString()
    public String toString() {
        return this.string.toString();
    }
};

method call =>> marshaller.marshal( (Object) toWrite , (OutputStream) output);

then to print the string or get it just reference the "output" stream itself As an example, to print the string out to console =>> System.out.println(output);

FYI: my method call marshaller.marshal(Object,Outputstream) is for working with XML. It is irrelevant to this topic.

This is highly wasteful for productional use, there is a way too many conversion and it is a bit loose. This was just coded to prove to you that it is totally possible to create a custom OuputStream and output a string. But just go Horcrux7 way and all is good with merely two method calls.

And the world lives on another day....

One major disadvantage of SPA - SEO. Only recently Google and Bing started indexing Ajax-based pages by executing JavaScript during crawling, and still in many cases pages are being indexed incorrectly.

While developing SPA, you will be forced to handle SEO issues, probably by post-rendering all your site and creating static html snapshots for crawler's use. This will require a solid investment in a proper infrastructures.

Update 19.06.16:

Since writing this answer a while ago, I gain much more experience with Single Page Apps (namely, AngularJS 1.x) - so I have more info to share.

In my opinion, the main disadvantage of SPA applications is SEO, making them limited to kind of "dashboard" apps only. In addition, you are going to have a much harder times with caching, compared to classic solutions. For example, in ASP.NET caching is extreamly easy - just turn on OutputCaching and you are good: the whole HTML page will be cached according to URL (or any other parameters). However, in SPA you will need to handle caching yourself (by using some solutions like second level cache, template caching, etc..).

Simply inside the loop write <?php the_post_thumbnail_url(); ?> as shown below:-

$args=array('post_type' => 'your_custom_post_type_slug','order' => 'DESC','posts_per_page'=> -1) ;
$the_qyery= new WP_Query($args);

if ($the_qyery->have_posts()) :
    while ( $the_qyery->have_posts() ) : $the_qyery->the_post();?>

<div class="col col_4_of_12">
    <div class="article_standard_view">
        <article class="item">
            <div class="item_header">
                <a href="<?php the_permalink(); ?>"><img src="<?php the_post_thumbnail_url(); ?>" alt="Post"></a>
            </div>

        </article>
    </div>
</div>            
<?php endwhile; endif; ?>

maybe this can help..

SELECT constraint_name, constraint_type, column_name
from user_constraints natural join user_cons_columns
where table_name = "my_table_name";

Maybe it's an entirely different situation, but I always got WebView[43046:188825] Could not signal service com.apple.WebKit.WebContent: 113: Could not find specified service when opening a webpage on the simulator while having the debugger attached to it. If I end the debugger and opening the app again the webpage will open just fine. This doesn't happen on the devices.

After spending an entire work-day trying to figure out what's wrong, I found out that if we have a framework named Preferences, UIWebView and WKWebView will not be able to open a webpage and will throw the error above.

To reproduce this error just make a simple app with WKWebView to show a webpage. Then create a new framework target and name it Preferences. Then import it to the main target and run the simulator again. WKWebView will fail to open a webpage.

So, it might be unlikely, but if you have a framework with the name Preferences, try deleting or renaming it.

Also, if anyone has an explanation for this please do share.

BTW, I was on Xcode 9.2.

To be certain that a folder exists (and not a file) I use this function:

Public Function FolderExists(strFolderPath As String) As Boolean
    On Error Resume Next
    FolderExists = ((GetAttr(strFolderPath) And vbDirectory) = vbDirectory)
    On Error GoTo 0
End Function

It works both, with \ at the end and without.

You can use define window.myvar = {}. When you want to use it, you can use like window.myvar = 1

Yes basically this is what virtualenv do , and this is what the activate command is for, from the doc here:

activate script

In a newly created virtualenv there will be a bin/activate shell script, or a Scripts/activate.bat batch file on Windows.

This will change your $PATH to point to the virtualenv bin/ directory. Unlike workingenv, this is all it does; it's a convenience. But if you use the complete path like /path/to/env/bin/python script.py you do not need to activate the environment first. You have to use source because it changes the environment in-place. After activating an environment you can use the function deactivate to undo the changes.

The activate script will also modify your shell prompt to indicate which environment is currently active.

so you should just use activate command which will do all that for you:

> \path\to\env\bin\activate.bat

As commented by Thomas W. - I almost missed this comment but I had the same issues so it's worth rewriting as an answer I think.

The main issue being that after the first assignment of webBrowser1.DocumentText to some html, subsequent assignments had no effect.

The solution as linked by Thomas can be found in detail at http://weblogs.asp.net/gunnarpeipman/archive/2009/08/15/displaying-custom-html-in-webbrowser-control.aspx however I will summarize below in case this page becomes unavailable in the future.

In short, due to the way the webBrowser control works, you must navigate to a new page each time you wish to change the content. Therefore the author proposes a method to update the control as:

private void DisplayHtml(string html)
{
    webBrowser1.Navigate("about:blank");
    if (webBrowser1.Document != null)
    {
        webBrowser1.Document.Write(string.Empty);
    }
    webBrowser1.DocumentText = html;
}

I have however found that in my current application I get a CastException from the line if(webBrowser1.Document != null). I'm not sure why this is, but I've found that if I wrap the whole if block in a try catch the desired effect still works. See:

private void DisplayHtml(string html)
{
    webBrowser1.Navigate("about:blank");
    try
    {
        if (webBrowser1.Document != null)
        {
            webBrowser1.Document.Write(string.Empty);
        }
    }
    catch (CastException e)
    { } // do nothing with this
    webBrowser1.DocumentText = html;
}

So every time the function to DisplayHtml is executed I receive a CastException from the if statement, so the contents of the if statement are never reached. However if I comment out the if statement so as not to receive the CastException, then the browser control doesn't get updated. I suspect there is another side effect of the code behind the Document property which causes this effect despite the fact that it also throws an exception.

Anyway I hope this helps people.

you can set pointer on last position of textbox as per following.

temp=$("#txtName").val();
$("#txtName").val('');
$("#txtName").val(temp);
$("#txtName").focus();

With most .net unit testing frameworks you can put an [ExpectedException] attribute on the test method. However this can't tell you that the exception happened at the point you expected it to. That's where xunit.net can help.

With xunit you have Assert.Throws, so you can do things like this:

    [Fact]
    public void CantDecrementBasketLineQuantityBelowZero()
    {
        var o = new Basket();
        var p = new Product {Id = 1, NetPrice = 23.45m};
        o.AddProduct(p, 1);
        Assert.Throws<BusinessException>(() => o.SetProductQuantity(p, -3));
    }

[Fact] is the xunit equivalent of [TestMethod]

<?php
set_time_limit(0);
//This is the file where we save the    information
$fp = fopen (dirname(__FILE__) . '/localfile.tmp', 'w+');
//Here is the file we are downloading, replace spaces with %20
$ch = curl_init(str_replace(" ","%20",$url));
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
// write curl response to file
curl_setopt($ch, CURLOPT_FILE, $fp); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// get curl response
curl_exec($ch); 
curl_close($ch);
fclose($fp);
?>

Convert Double to Float

public static Float convertToFloat(Double doubleValue) {
    return doubleValue == null ? null : doubleValue.floatValue();
}

Convert double to Float

public static Float convertToFloat(double doubleValue) {
    return (float) doubleValue;
}

In Laravel use Carbon its good

{{ \Carbon\Carbon::parse($user->from_date)->format('d/m/Y')}}

Here's a one liner that doesn't require jquery using Node.contains:

// Get arbitrary element with id "my-element"
var myElementToCheckIfClicksAreInsideOf = document.querySelector('#my-element');
// Listen for click events on body
document.body.addEventListener('click', function (event) {
    if (myElementToCheckIfClicksAreInsideOf.contains(event.target)) {
        console.log('clicked inside');
    } else {
        console.log('clicked outside');
    }
});

If you're wondering about the edge case of checking if the click is on the element itself, Node.contains returns true for the element itself (e.g. element.contains(element) === true) so this snippet should always work.

Browser support seems to cover pretty much everything according to that MDN page as well.

Add a Console.ReadKey call to your program to force it to wait for you to press a key before exiting.

Check out Google's Gson: http://code.google.com/p/google-gson/

From their website:

Gson gson = new Gson(); // Or use new GsonBuilder().create();
MyType target2 = gson.fromJson(json, MyType.class); // deserializes json into target2

You would just need to make a MyType class (renamed, of course) with all the fields in the json string. It might get a little more complicated when you're doing the arrays, if you prefer to do all of the parsing manually (also pretty easy) check out http://www.json.org/ and download the Java source for the Json parser objects.

Here's an alternative method that uses only the numpy package. It takes advantage of numpy's array functions, so may be faster when interpolating/extrapolating large arrays:

import numpy as np

def extrap(x, xp, yp):
    """np.interp function with linear extrapolation"""
    y = np.interp(x, xp, yp)
    y = np.where(x<xp[0], yp[0]+(x-xp[0])*(yp[0]-yp[1])/(xp[0]-xp[1]), y)
    y = np.where(x>xp[-1], yp[-1]+(x-xp[-1])*(yp[-1]-yp[-2])/(xp[-1]-xp[-2]), y)
    return y

x = np.arange(0,10)
y = np.exp(-x/3.0)
xtest = np.array((8.5,9.5))

print np.exp(-xtest/3.0)
print np.interp(xtest, x, y)
print extrap(xtest, x, y)

Edit: Mark Mikofski's suggested modification of the "extrap" function:

def extrap(x, xp, yp):
    """np.interp function with linear extrapolation"""
    y = np.interp(x, xp, yp)
    y[x < xp[0]] = yp[0] + (x[x<xp[0]]-xp[0]) * (yp[0]-yp[1]) / (xp[0]-xp[1])
    y[x > xp[-1]]= yp[-1] + (x[x>xp[-1]]-xp[-1])*(yp[-1]-yp[-2])/(xp[-1]-xp[-2])
    return y

Try:

expect(t).rejects.toThrow()

You can use -

Ternary oprator to check wheather value set by POST/GET or not somthing like this

$value1 = $_POST['value1'] = isset($_POST['value1']) ? $_POST['value1'] : '';
$value2 = $_POST['value2'] = isset($_POST['value2']) ? $_POST['value2'] : '';
$value3 = $_POST['value3'] = isset($_POST['value3']) ? $_POST['value3'] : '';
$value4 = $_POST['value4'] = isset($_POST['value4']) ? $_POST['value4'] : '';

export my store variable

export const store = createStore(rootReducer, applyMiddleware(ReduxThunk));

in action file or your file need them import this (store)

import {store} from "./path...";

this step get sate from store variable with function

const state = store.getState();

and get all of state your app

You can have the script call itself with psexec's -h option to run elevated.

I'm not sure how you would detect if it's already running as elevated or not... maybe re-try with elevated perms only if there's an Access Denied error?

Or, you could simply have the commands for the xcopy and reg.exe always be run with psexec -h, but it would be annoying for the end-user if they need to input their password each time (or insecure if you included the password in the script)...

I have resolved the same problem using the below code:

String query = "SELECT violationDate, COUNT(*) as date " +
            "FROM challan " +
            "WHERE challanType = '" + type + "' GROUP BY violationDate";
    

Here violationDate and date are two columns of the result table. date column will return occurrence.

Thanks to Chris for his awesome answer, I took it one step further and automated the process of running those statements (my table had over 8,000 permissions)

if object_id('dbo.tempPermissions') is not null
Drop table dbo.tempPermissions

Create table tempPermissions(ID int identity , Queries Varchar(255))


Insert into tempPermissions(Queries)


select 'GRANT ' + dp.permission_name collate latin1_general_cs_as
   + ' ON ' + s.name + '.' + o.name + ' TO ' + dpr.name 
   FROM sys.database_permissions AS dp
   INNER JOIN sys.objects AS o ON dp.major_id=o.object_id
   INNER JOIN sys.schemas AS s ON o.schema_id = s.schema_id
   INNER JOIN sys.database_principals AS dpr ON dp.grantee_principal_id=dpr.principal_id
   WHERE dpr.name NOT IN ('public','guest')

declare @count int, @max int, @query Varchar(255)
set @count =1
set @max = (Select max(ID) from tempPermissions)
set @query = (Select Queries from tempPermissions where ID = @count)

while(@count < @max)
begin
exec(@query)
set @count += 1
set @query = (Select Queries from tempPermissions where ID = @count)
end

select * from tempPermissions

drop table tempPermissions

additionally to restrict it to a single table add:

  and o.name = 'tablename'

after the WHERE dpr.name NOT IN ('public','guest') and remember to edit the select statement so that it generates statements for the table you want to grant permissions 'TO' Not the table the permissions are coming 'FROM' (which is what the script does).

What worked for me was to import the project with "File -> New -> Project from Version Control" then choose your online source (GitHub for example). This way all the .gradle files were created in the import.

I am an operating system that only allocates you memory in 10mb partitions.

Internal Fragmentation

• You ask for 17mb of memory
• I give you 20mb of memory

Fulfilling this request has just led to 3mb of internal fragmentation.

External Fragmentation

• You ask for 20mb of memory
• I give you 20mb of memory
• The 20mb of memory that I give you is not immediately contiguous next to another existing piece of allocated memory. In so handing you this memory, I have "split" a single unallocated space into two spaces.

Fulfilling this request has just led to external fragmentation

Just my two cents. If you are using Bootstrap 3 then I would just add an extra style into your own site's stylesheet which controls the text-left style of the control-label.

If you were to add text-left to the label, by default there is another style which overrides this .form-horizontal .control-label. So if you add:

.form-horizontal .control-label.text-left{
    text-align: left;
}

Then the built in text-left style is applied to the label correctly.

We can change the default parallelism using the following property:

-Djava.util.concurrent.ForkJoinPool.common.parallelism=16

which can set up to use more parallelism.

No, the methods don't need to be synchronized, and you don't need to define any methods; they are already in ConcurrentLinkedQueue, just use them. ConcurrentLinkedQueue does all the locking and other operations you need internally; your producer(s) adds data into the queue, and your consumers poll for it.

First, create your queue:

Queue<YourObject> queue = new ConcurrentLinkedQueue<YourObject>();

Now, wherever you are creating your producer/consumer objects, pass in the queue so they have somewhere to put their objects (you could use a setter for this, instead, but I prefer to do this kind of thing in a constructor):

YourProducer producer = new YourProducer(queue);

and:

YourConsumer consumer = new YourConsumer(queue);

and add stuff to it in your producer:

queue.offer(myObject);

and take stuff out in your consumer (if the queue is empty, poll() will return null, so check it):

YourObject myObject = queue.poll();

For more info see the Javadoc

EDIT:

If you need to block waiting for the queue to not be empty, you probably want to use a LinkedBlockingQueue, and use the take() method. However, LinkedBlockingQueue has a maximum capacity (defaults to Integer.MAX_VALUE, which is over two billion) and thus may or may not be appropriate depending on your circumstances.

If you only have one thread putting stuff into the queue, and another thread taking stuff out of the queue, ConcurrentLinkedQueue is probably overkill. It's more for when you may have hundreds or even thousands of threads accessing the queue at the same time. Your needs will probably be met by using:

Queue<YourObject> queue = Collections.synchronizedList(new LinkedList<YourObject>());

A plus of this is that it locks on the instance (queue), so you can synchronize on queue to ensure atomicity of composite operations (as explained by Jared). You CANNOT do this with a ConcurrentLinkedQueue, as all operations are done WITHOUT locking on the instance (using java.util.concurrent.atomic variables). You will NOT need to do this if you want to block while the queue is empty, because poll() will simply return null while the queue is empty, and poll() is atomic. Check to see if poll() returns null. If it does, wait(), then try again. No need to lock.

Finally:

Honestly, I'd just use a LinkedBlockingQueue. It is still overkill for your application, but odds are it will work fine. If it isn't performant enough (PROFILE!), you can always try something else, and it means you don't have to deal with ANY synchronized stuff:

BlockingQueue<YourObject> queue = new LinkedBlockingQueue<YourObject>();

queue.put(myObject); // Blocks until queue isn't full.

YourObject myObject = queue.take(); // Blocks until queue isn't empty.

Everything else is the same. Put probably won't block, because you aren't likely to put two billion objects into the queue.

This is possible too:

using System.Web.Helpers;
var listOfObjectsResult = Json.Decode<List<DataType>>(JsonData);

Perhaps use plt.annotate:

import numpy as np
import matplotlib.pyplot as plt

N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]

plt.subplots_adjust(bottom = 0.1)
plt.scatter(
    data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
    cmap=plt.get_cmap('Spectral'))

for label, x, y in zip(labels, data[:, 0], data[:, 1]):
    plt.annotate(
        label,
        xy=(x, y), xytext=(-20, 20),
        textcoords='offset points', ha='right', va='bottom',
        bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
        arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))

plt.show()

For ansible, and using hyphen, this worked for me:

    - name: free-ud-ssd-space-in-percent
      debug:
        var: clusterInfo.json.content["free-ud-ssd-space-in-percent"]

If you installed mongodb with homebrew, there's an easier way:

List mongo job with launchctl:

launchctl list | grep mongo

Stop mongo job:

launchctl stop <job label>

(For me this is launchctl stop homebrew.mxcl.mongodb)

Start mongo job:

launchctl start <job label>

Swift 3.1 You can do this by implementing the delegate method of UINavigationController.

func navigationController(_ navigationController: UINavigationController, 
                          willShow viewController: UIViewController, animated: Bool) {

    /** It'll hide the Title with back button only,
     ** we'll still get the back arrow image and default functionality.
     */
    let item = UIBarButtonItem(title: " ", style: .plain, target: nil, 
                               action: nil)
    viewController.navigationItem.backBarButtonItem = item
}

What about android:textAllCaps?

When using request for an http POST you can add parameters this way:

var request = require('request');
request.post({
  url:     'http://localhost/test2.php',
  form:    { mes: "heydude" }
}, function(error, response, body){
  console.log(body);
});

You have to provide the full path that you want to import.

import com.my.stuff.main.Main;
import com.my.stuff.second.*;

So, in your main class, you'd have:

package com.my.stuff.main

import com.my.stuff.second.Second;   // THIS IS THE IMPORTANT LINE FOR YOUR QUESTION

class Main {
   public static void main(String[] args) {
      Second second = new Second();
      second.x();  
   }
}

EDIT: adding example in response to Shawn D's comment

There is another alternative, as Shawn D points out, where you can specify the full package name of the object that you want to use. This is very useful in two locations. First, if you're using the class exactly once:

class Main {
    void function() {
        int x = my.package.heirarchy.Foo.aStaticMethod();

        another.package.heirarchy.Baz b = new another.package.heirarchy.Bax();
    }
}

Alternatively, this is useful when you want to differentiate between two classes with the same short name:

class Main {
    void function() {
        java.util.Date utilDate = ...;
        java.sql.Date sqlDate = ...;
    }
}

User.hasMany(Post, {foreignKey: 'user_id'})
Post.belongsTo(User, {foreignKey: 'user_id'})

Post.find({ where: { ...}, include: [User]})

Which will give you

SELECT
  `posts`.*,
  `users`.`username` AS `users.username`, `users`.`email` AS `users.email`,
  `users`.`password` AS `users.password`, `users`.`sex` AS `users.sex`,
  `users`.`day_birth` AS `users.day_birth`,
  `users`.`month_birth` AS `users.month_birth`,
  `users`.`year_birth` AS `users.year_birth`, `users`.`id` AS `users.id`,
  `users`.`createdAt` AS `users.createdAt`,
  `users`.`updatedAt` AS `users.updatedAt`
FROM `posts`
  LEFT OUTER JOIN `users` AS `users` ON `users`.`id` = `posts`.`user_id`;

The query above might look a bit complicated compared to what you posted, but what it does is basically just aliasing all columns of the users table to make sure they are placed into the correct model when returned and not mixed up with the posts model

Other than that you'll notice that it does a JOIN instead of selecting from two tables, but the result should be the same

You need to use the val() function to get the textbox value. text does not exist as a property only as a function and even then its not the correct function to use in this situation.

var from = $("input#fromAddress").val()

val() is the standard function for getting the value of an input.

1. To properly purge the queue of waiting tasks you have to stop all the workers (http://celery.readthedocs.io/en/latest/faq.html#i-ve-purged-messages-but-there-are-still-messages-left-in-the-queue):

$ sudo rabbitmqctl stop

or (in case RabbitMQ/message broker is managed by Supervisor):

$ sudo supervisorctl stop all

2. ...and then purge the tasks from a specific queue:

$ cd <source_dir>
$ celery amqp queue.purge <queue name>

3. Start RabbitMQ:

$ sudo rabbitmqctl start

or (in case RabbitMQ is managed by Supervisor):

$ sudo supervisorctl start all

My requirement was slightly different than the question, still this is also a useful way of stopping the thread to be executing its tasks. All I wanted to do is to stop the thread on exiting the screen and resumes while returning to the screen.

As per the Android docs, this would be the proposed replacement for stop method which has been deprecated from API 15

Many uses of stop should be replaced by code that simply modifies some variable to indicate that the target thread should stop running. The target thread should check this variable regularly, and return from its run method in an orderly fashion if the variable indicates that it is to stop running.

My Thread class

   class ThreadClass implements Runnable {
            ...
                  @Override
                        public void run() {
                            while (count < name.length()) {

                                if (!exited) // checks boolean  
                                  {
                                   // perform your task
                                                     }
            ...

OnStop and OnResume would look like this

  @Override
    protected void onStop() {
        super.onStop();
        exited = true;
    }

    @Override
    protected void onResume() {
        super.onResume();
        exited = false;
    }

I think a lot of people are wanting to be able to check to see if their variable is not empty as well as if it exists. I think that checking for existence and emptiness is a good idea in a lot of cases, and makes your template more robust and less prone to silly errors. In other words, if you check to make sure your variable is not null AND not empty before using it, then your template becomes more flexible, because you can throw either a null variable or an empty string into it, and it will work the same in either case.

<#if p?? && p?has_content>1</#if>

Let's say you want to make sure that p is more than just whitespace. Then you could trim it before checking to see if it has_content.

<#if p?? && p?trim?has_content>1</#if>

UPDATE

Please ignore my suggestion -- has_content is all that is needed, as it does a null check along with the empty check. Doing p?? && p?has_content is equivalent to p?has_content, so you may as well just use has_content.

No, in C++ you cannot call a constructor from a constructor. What you can do, as warren pointed out, is:

• Overload the constructor, using different signatures
• Use default values on arguments, to make a "simpler" version available

Note that in the first case, you cannot reduce code duplication by calling one constructor from another. You can of course have a separate, private/protected, method that does all the initialization, and let the constructor mainly deal with argument handling.

This method takes one Function as an argument, this function accepts one parameter T as an input argument and return one stream of parameter R as a return value. When this function is applied on each element of this stream, it produces a stream of new values. All the elements of these new streams generated by each element are then copied to a new stream, which will be a return value of this method.

All what you have to do is to select and download the bootstrap.css and bootstrap.js files from Bootswatch website, and then replace the original files with them.

Of course you have to add the paths to your layout page after the jQuery path that is all.

It's difficult to answer this question with the information given. Nothing looks particularly wrong with how you are using HashSet.

Well, I'll hazard a guess that it's not a compilation issue and, when you say "getting errors," you mean "not getting the behavior [you] want."

I'll also go out on a limb and suggest that maybe your Block's equals an hashCode methods are not properly overridden.

just add .col-xs-12 to your responsive image. It's should work.

There are several tools which can import Excel to SQL Server.

I am using DbTransfer (http://www.dbtransfer.com/Products/DbTransfer) to do the job. It's primarily focused on transfering data between databases and excel, xml, etc...

I have tried the openrowset method and the SQL Server Import / Export Assitant before. But I found these methods to be unnecessary complicated and error prone in constrast to doing it with one of the available dedicated tools.

If you want a TRIE implemented as a Python class, here is something I wrote after reading about them:

class Trie:

    def __init__(self):
        self.__final = False
        self.__nodes = {}

    def __repr__(self):
        return 'Trie<len={}, final={}>'.format(len(self), self.__final)

    def __getstate__(self):
        return self.__final, self.__nodes

    def __setstate__(self, state):
        self.__final, self.__nodes = state

    def __len__(self):
        return len(self.__nodes)

    def __bool__(self):
        return self.__final

    def __contains__(self, array):
        try:
            return self[array]
        except KeyError:
            return False

    def __iter__(self):
        yield self
        for node in self.__nodes.values():
            yield from node

    def __getitem__(self, array):
        return self.__get(array, False)

    def create(self, array):
        self.__get(array, True).__final = True

    def read(self):
        yield from self.__read([])

    def update(self, array):
        self[array].__final = True

    def delete(self, array):
        self[array].__final = False

    def prune(self):
        for key, value in tuple(self.__nodes.items()):
            if not value.prune():
                del self.__nodes[key]
        if not len(self):
            self.delete([])
        return self

    def __get(self, array, create):
        if array:
            head, *tail = array
            if create and head not in self.__nodes:
                self.__nodes[head] = Trie()
            return self.__nodes[head].__get(tail, create)
        return self

    def __read(self, name):
        if self.__final:
            yield name
        for key, value in self.__nodes.items():
            yield from value.__read(name + [key])

The onTokenRefresh() method is going to be called whenever a new token is generated. Upon app install, it will be generated immediately (as you have found to be the case). It will also be called when the token has changed.

According to the FirebaseCloudMessaging guide:

You can target notifications to a single, specific device. On initial startup of your app, the FCM SDK generates a registration token for the client app instance.

Source Link: https://firebase.google.com/docs/notifications/android/console-device#access_the_registration_token

This means that the token registration is per app. It sounds like you would like to utilize the token after a user is logged in. What I would suggest is that you save the token in the onTokenRefresh() method to internal storage or shared preferences. Then, retrieve the token from storage after a user logs in and register the token with your server as needed.

If you would like to manually force the onTokenRefresh(), you can create an IntentService and delete the token instance. Then, when you call getToken, the onTokenRefresh() method will be called again.

Example Code:

public class DeleteTokenService extends IntentService
{
    public static final String TAG = DeleteTokenService.class.getSimpleName();

    public DeleteTokenService()
    {
        super(TAG);
    }

    @Override
    protected void onHandleIntent(Intent intent)
    {
        try
        {
            // Check for current token
            String originalToken = getTokenFromPrefs();
            Log.d(TAG, "Token before deletion: " + originalToken);

            // Resets Instance ID and revokes all tokens.
            FirebaseInstanceId.getInstance().deleteInstanceId();

            // Clear current saved token
            saveTokenToPrefs("");

            // Check for success of empty token
            String tokenCheck = getTokenFromPrefs();
            Log.d(TAG, "Token deleted. Proof: " + tokenCheck);

            // Now manually call onTokenRefresh()
            Log.d(TAG, "Getting new token");
            FirebaseInstanceId.getInstance().getToken();
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }

    private void saveTokenToPrefs(String _token)
    {
        // Access Shared Preferences
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
        SharedPreferences.Editor editor = preferences.edit();

        // Save to SharedPreferences
        editor.putString("registration_id", _token);
        editor.apply();
    }

    private String getTokenFromPrefs()
    {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
        return preferences.getString("registration_id", null);
    }
}

EDIT

FirebaseInstanceIdService

public class FirebaseInstanceIdService extends Service

This class is deprecated. In favour of overriding onNewToken in FirebaseMessagingService. Once that has been implemented, this service can be safely removed.

onTokenRefresh() is deprecated. Use onNewToken() in MyFirebaseMessagingService

public class MyFirebaseMessagingService extends FirebaseMessagingService {

@Override
public void onNewToken(String s) {
    super.onNewToken(s);
    Log.e("NEW_TOKEN",s);
    }

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    }

Easiest way I find for multiple searches is to pipe them all (probably heavier CPU use) but for your example user:

Get-EventLog -LogName Security | where {$_.UserName -notlike "*user1"} |  where {$_.UserName -notlike "*user2"}

A byte is 8 bits (binary data).

A byte array is an array of bytes (tautology FTW!).

You could use a byte array to store a collection of binary data, for example, the contents of a file. The downside to this is that the entire file contents must be loaded into memory.

For large amounts of binary data, it would be better to use a streaming data type if your language supports it.

For question 1:

SELECT DISTINCT a.*
  FROM [Table] a
  INNER JOIN
  [Table] b
  ON
  a.C1 <> b.C1 AND a.C2 = b.C2 AND a.C3 = b.C3 AND a.C4 = b.C4

Using an inner join is much more efficient than a subquery because it requires fewer operations, and maintains the use of indexes when comparing the values, allowing the SQL server to better optimize the query before its run. Using appropriate indexes with this query can bring your query down to only n * log(n) rows to compare.

Using a subquery with your where clause or only doing a standard join where C1 does not equal C2 results in a table that has roughly 2 to the power of n rows to compare, where n is the number of rows in the table.

So by using proper indexing with an Inner Join, which only returns records which met the join criteria, we're able to drastically improve the performance. Also note that we return DISTINCT a.*, because this will only return the columns for table a where the join criteria was met. Returning * would return the columns for both a and b where the criteria was met, and not including DISTINCT would result in a duplicate of each row for each time that row row matched another row more than once.

A similar approach could also be performed using CROSS APPLY, which still uses a subquery, but makes use of indexes more efficiently.

An implementation with the keyword USING instead of ON could also work, but the syntax is more complicated to make work because your want to match on rows where C1 does not match, so you would need an additional where clause to filter out matching each row with itself. Also, USING is not compatible/allowed in conjunction with table values in all implementations of SQL, so it's best to stick with ON.

Similarly, for question 2:

SELECT DISTINCT a.*
  FROM [Table] a
  INNER JOIN
  [Table] b
  ON
  a.C1 <> b.C1 AND a.C4 = b.C4

This is essentially the same query as for 1, but because it only wants to know which rows match for C4, we only compare on the rows for C4.

parseInt() should do the trick

var number = "25";
var sum = parseInt(number, 10) + 10;
var pin = number + 10;

Gives you

sum == 35
pin == "2510"

Note: The 10 in parseInt(number, 10) specifies decimal (base-10). Without this some browsers may not interpret the string correctly. See MDN: parseInt.

When your class implements Comparable, the compareTo method of the class is defining the "natural" ordering of that object. That method is contractually obligated (though not demanded) to be in line with other methods on that object, such as a 0 should always be returned for objects when the .equals() comparisons return true.

A Comparator is its own definition of how to compare two objects, and can be used to compare objects in a way that might not align with the natural ordering.

For example, Strings are generally compared alphabetically. Thus the "a".compareTo("b") would use alphabetical comparisons. If you wanted to compare Strings on length, you would need to write a custom comparator.

In short, there isn't much difference. They are both ends to similar means. In general implement comparable for natural order, (natural order definition is obviously open to interpretation), and write a comparator for other sorting or comparison needs.

Marc B's answer is mostly correct.

If you are using a nonbinary string (CHAR, VARCHAR, TEXT), comparisons are case-insensitive, per the default collation.

If you are using a binary string (BINARY, VARBINARY, BLOB), comparisons are case-sensitive, so you'll need to use LOWER as described in other answers.

If you are not using the default collation and you are using a nonbinary string, case sensitivity is decided by the chosen collation.

Source: https://dev.mysql.com/doc/refman/8.0/en/case-sensitivity.html. Read closely. Some others have mistaken it to say that comparisons are necessarily case-sensitive or insensitive. This is not the case.

Read Byte by Byte and check that each byte against '\n' if it is not, then store it into buffer
if it is '\n' add '\0' to buffer and then use atoi()

You can read a single byte like this

char c;
read(fd,&c,1);

See read()

Simple: active the accordion to a class, and then create divs with this, like multiples instances of accordion.

Like this:

JS

$(function() {
    $( ".accordion" ).accordion({
        collapsible: true,
        clearStyle: true,
        active: false,
    })
});

HTML

<div class="accordion">
    <h3>Title</h3>
    <p>lorem</p>
</div>
<div class="accordion">
    <h3>Title</h3>
    <p>lorem</p>
</div>
<div class="accordion">
    <h3>Title</h3>
    <p>lorem</p>
</div>

You could use

var a = document.querySelector('a[data-a="1"]');

instead of

var a = document.querySelector('a[data-a=1]');

I appreciate the help, I do think I have found a solution if someone would comment on the effectiveness I would appreciate it. Essentially what I did is. I realize it is somewhat static in its implementation but I does what I need it to do (forgive incorrect syntax)

SELECT
  ordered_item.id as `Id`,
  ordered_item.Item_Name as `ItemName`,
  Options1.Value
  Options2.Value
FROM ORDERED_ITEMS
LEFT JOIN (Ordered_Options as Options1)
    ON (Options1.Ordered_Item.ID = Ordered_Options.Ordered_Item_ID 
        AND Options1.Option_Number = 43)
LEFT JOIN (Ordered_Options as Options2)
    ON (Options2.Ordered_Item.ID = Ordered_Options.Ordered_Item_ID
        AND Options2.Option_Number = 44);

NullPointerExceptions are among the easier exceptions to diagnose, frequently. Whenever you get an exception in Java and you see the stack trace ( that's what your second quote-block is called, by the way ), you read from top to bottom. Often, you will see exceptions that start in Java library code or in native implementations methods, for diagnosis you can just skip past those until you see a code file that you wrote.

Then you like at the line indicated and look at each of the objects ( instantiated classes ) on that line -- one of them was not created and you tried to use it. You can start by looking up in your code to see if you called the constructor on that object. If you didn't, then that's your problem, you need to instantiate that object by calling new Classname( arguments ). Another frequent cause of NullPointerExceptions is accidentally declaring an object with local scope when there is an instance variable with the same name.

In your case, the exception occurred in your constructor for Workshop on line 75. <init> means the constructor for a class. If you look on that line in your code, you'll see the line

denimjeansButton.addItemListener(this);

There are fairly clearly two objects on this line: denimjeansButton and this. this is synonymous with the class instance you are currently in and you're in the constructor, so it can't be this. denimjeansButton is your culprit. You never instantiated that object. Either remove the reference to the instance variable denimjeansButton or instantiate it.

Every derived table (AKA sub-query) must indeed have an alias. I.e. each query in brackets must be given an alias (AS whatever), which can the be used to refer to it in the rest of the outer query.

SELECT ID FROM (
    SELECT ID, msisdn FROM (
        SELECT * FROM TT2
    ) AS T
) AS T

In your case, of course, the entire query could be replaced with:

SELECT ID FROM TT2

In android studio with gradle you can have multiple source directors which will allow you to separate resources. For example:

android {
    ....
    android.sourceSets {
        main.res.srcDirs = ['src/main/extraresdirnamed_sandwiches', 'src/main/res']
    }
    ....
}

However the names must not collide which means you will still need to have names such as sandwiches_tunaOnRye but you will be able to have a seperate section for all of your sandwiches.

This allows you to store your resources in different structures (useful for auto generated content such as actionbargenerator)

2. I only tried this function with modern browsers, it won't work for old browsers where vendors are required (and IE of course)

Try to use appendChild method:

In Tomcat6, You can conditionally enable from your HTTP Listener Class:

public void contextInitialized(ServletContextEvent event) {                 
   if (Boolean.getBoolean("HTTP_ONLY_SESSION")) HttpOnlyConfig.enable(event);
}

Using this class

import java.lang.reflect.Field;
import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import org.apache.catalina.core.StandardContext;
public class HttpOnlyConfig
{
    public static void enable(ServletContextEvent event)
    {
        ServletContext servletContext = event.getServletContext();
        Field f;
        try
        { // WARNING TOMCAT6 SPECIFIC!!
            f = servletContext.getClass().getDeclaredField("context");
            f.setAccessible(true);
            org.apache.catalina.core.ApplicationContext ac = (org.apache.catalina.core.ApplicationContext) f.get(servletContext);
            f = ac.getClass().getDeclaredField("context");
            f.setAccessible(true);
            org.apache.catalina.core.StandardContext sc = (StandardContext) f.get(ac);
            sc.setUseHttpOnly(true);
        }
        catch (Exception e)
        {
            System.err.print("HttpOnlyConfig cant enable");
            e.printStackTrace();
        }
    }
}

Make sure that the htaccess file is readable by apache:

chmod 644 /var/www/abc/.htaccess 

And make sure the directory it's in is readable and executable:

chmod 755 /var/www/abc/

Just replace the first line with the below;

SqlConnection con = new SqlConnection("Server=localhost;Database=employeedetails;Trusted_Connection=True");

  expect($rootScope.$eval('a+1', {a: 2})).toBe(3);

  $rootScope.$eval(function(scope, locals) {
    scope.c = locals.b + 4;
  }, {b: 3});
  expect($rootScope.c).toBe(7);
}));

We also can pass locals for evaluation expression.

The Problem

In MySQL, certain words like SELECT, INSERT, DELETE etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.

As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):

Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.

...

If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.

...

The identifier quote character is the backtick ("`"):

A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.

• ADD
• AND
• BEFORE
• BY
• CALL
• CASE
• CONDITION
• DELETE
• DESC
• DESCRIBE
• FROM
• GROUP
• IN
• INDEX
• INSERT
• INTERVAL
• IS
• KEY
• LIKE
• LIMIT
• LONG
• MATCH
• NOT
• OPTION
• OR
• ORDER
• PARTITION
• RANK
• REFERENCES
• SELECT
• TABLE
• TO
• UPDATE
• WHERE

The Solution

You have two options.

1. Don't use reserved words as identifiers

The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.

Doing this has a couple of advantages:

• It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.

• The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.

Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.

2. Use backticks

If renaming the table or column isn't possible, wrap the offending identifier in backticks (`) as described in the earlier quote from 10.2 Schema Object Names.

An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):

mysql> CREATE TABLE interval (begin INT, end INT);
ERROR 1064 (42000): You have an error in your SQL syntax.
near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT);
Query OK, 0 rows affected (0.01 sec)

Similarly, the query from the question can be fixed by wrapping the keyword key in backticks, as shown below:

INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)";               ^   ^

Simple answer is Add a subview and change it's alpha.

UIView *mainView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
UIView *subView = [[UIView alloc] initWithFrame:popupView.frame];
UIColor * backImgColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"blue_Img.png"]];
subView.backgroundColor = backImgColor;
subView.alpha = 0.5;
[mainView addSubview:subView];

I always avoid defining new variables as far as I can, and I find it a very good practice

A good explanation of how BFS computes shortest paths, accompanied by the most efficient simple BFS algorithm of which I'm aware and also by working code, is provided in the following peer-reviewed paper:

https://queue.acm.org/detail.cfm?id=3424304

The paper explains how BFS computes a shortest-paths tree represented by per-vertex parent pointers, and how to recover a particular shortest path between any two vertices from the parent pointers. The explanation of BFS takes three forms: prose, pseudocode, and a working C program.

The paper also describes "Efficient BFS" (E-BFS), a simple variant of classic textbook BFS that improves its efficiency. In the asymptotic analysis, running time improves from Theta(V+E) to Omega(V). In words: classic BFS always runs in time proportional to the number of vertices plus the number of edges, whereas E-BFS sometimes runs in time proportional to the number of vertices alone, which can be much smaller. In practice E-BFS can be much faster, depending on the input graph. E-BFS sometimes offers no advantage over classic BFS but it's never much slower.

Remarkably, despites its simplicity E-BFS appears not to be widely known.

If array is static allocated:

size_t size = sizeof(arr) / sizeof(int);

if array is dynamic allocated(heap):

int *arr = malloc(sizeof(int) * size);

where variable size is a dimension of the arr.

Beginning of line or beginning of string?

Start and end of string

/^CTR.*$/

/ = delimiter
^ = start of string
CTR = literal CTR
$ = end of string
.* = zero or more of any character except newline

Start and end of line

/^CTR.*$/m

/ = delimiter
^ = start of line
CTR = literal CTR
$ = end of line
.* = zero or more of any character except newline
m = enables multi-line mode, this sets regex to treat every line as a string, so ^ and $ will match start and end of line

While in multi-line mode you can still match the start and end of the string with \A\Z permanent anchors

/\ACTR.*\Z/m

\A = means start of string
CTR = literal CTR
.* = zero or more of any character except newline
\Z = end of string
m = enables multi-line mode

As such, another way to match the start of the line would be like this:

/(\A|\r|\n|\r\n)CTR.*/

or

/(^|\r|\n|\r\n)CTR.*/

\r = carriage return / old Mac OS newline
\n = line-feed / Unix/Mac OS X newline
\r\n = windows newline

Note, if you are going to use the backslash \ in some program string that supports escaping, like the php double quotation marks "" then you need to escape them first

so to run \r\nCTR.* you would use it as "\\r\\nCTR.*"

If you want to include foreign language letters as well, you can try:

String string = "hippopotamus";
if (string.matches("^[\\p{L}0-9']+$")){
    string is alphanumeric do something here...
}

Or if you wanted to allow a specific special character, but not any others. For example for # or space, you can try:

String string = "#somehashtag";
if(string.matches("^[\\p{L}0-9'#]+$")){
    string is alphanumeric plus #, do something here...
}

1) [WebService(Namespace = "http://tempuri.org/")]

later web service namespace changed to :

INTRODUCTION

This answer corrects the very broken but shockingly top voted answer of this thread (written by TheMarko):

#!/usr/bin/env bash

BASEDIR=$(dirname "$0")
echo "$BASEDIR"

WHY DOES USING dirname "$0" ON IT'S OWN NOT WORK?

dirname $0 will only work if user launches script in a very specific way. I was able to find several situations where this answer fails and crashes the script.

First of all, let's understand how this answer works. He's getting the script directory by doing

dirname "$0"

$0 represents the first part of the command calling the script (it's basically the inputted command without the arguments:

/some/path/./script argument1 argument2

$0="/some/path/./script"

dirname basically finds the last / in a string and truncates it there. So if you do:

  dirname /usr/bin/sha256sum

you'll get: /usr/bin

This example works well because /usr/bin/sha256sum is a properly formatted path but

  dirname "/some/path/./script"

wouldn't work well and would give you:

  BASENAME="/some/path/." #which would crash your script if you try to use it as a path

Say you're in the same dir as your script and you launch it with this command

./script   

$0 in this situation will be ./script and dirname $0 will give:

. #or BASEDIR=".", again this will crash your script

Using:

sh script

Without inputting the full path will also give a BASEDIR="."

Using relative directories:

 ../some/path/./script

Gives a dirname $0 of:

 ../some/path/.

If you're in the /some directory and you call the script in this manner (note the absence of / in the beginning, again a relative path):

 path/./script.sh

You'll get this value for dirname $0:

 path/. 

and ./path/./script (another form of the relative path) gives:

 ./path/.

The only two situations where basedir $0 will work is if the user use sh or touch to launch a script because both will result in $0:

 $0=/some/path/script

which will give you a path you can use with dirname.

THE SOLUTION

You'd have account for and detect every one of the above mentioned situations and apply a fix for it if it arises:

#!/bin/bash
#this script will only work in bash, make sure it's installed on your system.

#set to false to not see all the echos
debug=true

if [ "$debug" = true ]; then echo "\$0=$0";fi


#The line below detect script's parent directory. $0 is the part of the launch command that doesn't contain the arguments
BASEDIR=$(dirname "$0") #3 situations will cause dirname $0 to fail: #situation1: user launches script while in script dir ( $0=./script)
                                                                     #situation2: different dir but ./ is used to launch script (ex. $0=/path_to/./script)
                                                                     #situation3: different dir but relative path used to launch script
if [ "$debug" = true ]; then echo 'BASEDIR=$(dirname "$0") gives: '"$BASEDIR";fi                                 

if [ "$BASEDIR" = "." ]; then BASEDIR="$(pwd)";fi # fix for situation1

_B2=${BASEDIR:$((${#BASEDIR}-2))}; B_=${BASEDIR::1}; B_2=${BASEDIR::2}; B_3=${BASEDIR::3} # <- bash only
if [ "$_B2" = "/." ]; then BASEDIR=${BASEDIR::$((${#BASEDIR}-1))};fi #fix for situation2 # <- bash only
if [ "$B_" != "/" ]; then  #fix for situation3 #<- bash only
        if [ "$B_2" = "./" ]; then
                #covers ./relative_path/(./)script
                if [ "$(pwd)" != "/" ]; then BASEDIR="$(pwd)/${BASEDIR:2}"; else BASEDIR="/${BASEDIR:2}";fi
        else
                #covers relative_path/(./)script and ../relative_path/(./)script, using ../relative_path fails if current path is a symbolic link
                if [ "$(pwd)" != "/" ]; then BASEDIR="$(pwd)/$BASEDIR"; else BASEDIR="/$BASEDIR";fi
        fi
fi

if [ "$debug" = true ]; then echo "fixed BASEDIR=$BASEDIR";fi

Google Chrome Developer Tools has (a currently experimental) feature called CSS Overview which will allow you to find unused CSS rules.

To enable it follow these steps:

1. Open up DevTools (Command+Option+I on Mac; Control+Shift+I on Windows)
2. Head over to DevTool Settings (Function+F1 on Mac; F1 on Windows)
3. Click open the Experiments section
4. Enable the CSS Overview option

Use org.springframework.web.servlet.config.annotation.WebMvcConfigurer

With Spring Boot 2.1.4.RELEASE (Spring Framework 5.1.6.RELEASE), do like this

package vn.bkit;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; // Deprecated.
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
public class MvcConfiguration implements WebMvcConfigurer {

    @Bean
    public ViewResolver getViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/");
        resolver.setSuffix(".html");
        return resolver;
    }

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

}

I would recommend the call_user_func() or call_user_func_arrayphp methods. You can check them out here (call_user_func_array , call_user_func).

example

class Foo {
static public function test() {
    print "Hello world!\n";
}
}

 call_user_func('Foo::test');//FOO is the class, test is the method both separated by ::
 //or
 call_user_func(array('Foo', 'test'));//alternatively you can pass the class and method as an array

If you have arguments you are passing to the method , then use the call_user_func_array() function.

example.

class foo {
function bar($arg, $arg2) {
    echo __METHOD__, " got $arg and $arg2\n";
}
}

// Call the $foo->bar() method with 2 arguments
call_user_func_array(array("foo", "bar"), array("three", "four"));
//or
//FOO is the class, bar is the method both separated by ::
call_user_func_array("foo::bar"), array("three", "four"));

System apps installed /system/app/ or /system/priv-app. Other apps can be installed in /data/app or /data/preload/.

Connect to your android mobile with USB and run the following commands. You will see all the installed packages.

$ adb shell 

$ pm list packages -f

I am not sure, but maybe this logic would work.

var d = 10;
var prevDate = "";
var x = 0;
var oldVal = "";
var func = function (d) {
    if (x == 0 && d != prevDate && prevDate == "") {
        oldVal = d;
        prevDate = d;
    }
    else if (x == 1 && prevDate != d) {
        oldVal = prevDate;
        prevDate = d;
    }
    console.log(oldVal);
    x = 1;
};
/*
         ============================================
         Try:
         func(2);
         func(3);
         func(4);
*/

Use this:

String str = " 12,12"
str = str.replaceAll("(\\d+)\\,(\\d+)", "$1.$2");
System.out.println("str:"+str); //-> str:12.12

hope help you.

You have your ssh clone statement wrong: git clone username [email protected]:root/test.git

That statement would try to clone a repository named username into the location relative to your current path, [email protected]:root/test.git.

You want to leave out username:

git clone [email protected]:root/test.git

One way:

public string GetOSVersion()
{
  int _MajorVersion = Environment.OSVersion.Version.Major;

  switch (_MajorVersion) {
    case 5:
      return "Windows XP";
    case 6:
      switch (Environment.OSVersion.Version.Minor) {
        case 0:
          return "Windows Vista";
        case 1:
          return "Windows 7";
        default:
          return "Windows Vista & above";
      }
      break;
    default:
      return "Unknown";
  }
}

Then simply do wrap a select case around the function.

If your segue exists in the storyboard with a segue identifier between your two views, you can just call it programmatically using:

performSegue(withIdentifier: "mySegueID", sender: nil)

For older versions:

performSegueWithIdentifier("mySegueID", sender: nil)

You could also do:

presentViewController(nextViewController, animated: true, completion: nil)

Or if you are in a Navigation controller:

self.navigationController?.pushViewController(nextViewController, animated: true)

In many cases the purpose of a Null value is to serve for a data value that was not present in a previous version of your application.

So say you have an xml file from your application "ReportMaster" version 1.

Now in ReportMaster version 2 a some more attributes have been added that may or not be defined.

If you use the 'no tag means null' representation you get automatic backward compatibility for reading your ReportMaster 1 xml file.

Use functional operation for faster iteration.

team1.keySet().forEach((key) -> { System.out.println(key); });

$('#message').html('');

You can use this method too. Because everything between the open and close tag of textarea is html code.

Another option is to use summary function. It gives a summary of the Ts, Fs and NAs.

> summary(hival)
   Mode   FALSE    TRUE    NA's 
logical    4367      53    2076

                }
            }
            empty = false;
        }

        if (!empty) {
            if (count == 0) {
                count = 1;
            } else if (!lastEmpty) {
                count++;
            }
        }

        return count;
    }
}

Tested and very fast.

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

And for yet another option, I'd go with awk!

echo "foo bar <foo> bla 1 2 3.4" | awk '{ print $(NF-1), $NF; }'

This will split the input (I'm using STDIN here, but your input could easily be a file) on spaces, and then print out the last-but-one field, and then the last field. The $NF variables hold the number of fields found after exploding on spaces.

The benefit of this is that it doesn't matter if what precedes the last two fields changes, as long as you only ever want the last two it'll continue to work.

uint16_t is guaranteed to be a unsigned integer that is 16 bits large

unsigned short int is guaranteed to be a unsigned short integer, where short integer is defined by the compiler (and potentially compiler flags) you are currently using. For most compilers for x86 hardware a short integer is 16 bits large.

Also note that per the ANSI C standard only the minimum size of 16 bits is defined, the maximum size is up to the developer of the compiler

Minimum Type Limits

Any compiler conforming to the Standard must also respect the following limits with respect to the range of values any particular type may accept. Note that these are lower limits: an implementation is free to exceed any or all of these. Note also that the minimum range for a char is dependent on whether or not a char is considered to be signed or unsigned.

Type Minimum Range

signed char     -127 to +127
unsigned char      0 to 255
short int     -32767 to +32767
unsigned short int 0 to 65535

If you want to initialize an array in a constructor, you can't use those array initializer like.

data= {10,20,30,40,50,60,71,80,90,91};

Just change it to

data = new int[] {10,20,30,40,50,60,71,80,90,91};

You don't have to specify the size with data[10] = new int[] { 10,...,91} Just declare the property / field with int[] data; and initialize it like above. The corrected version of your code would look like the following:

public class Array {

    int[] data;

    public Array() {
        data = new int[] {10,20,30,40,50,60,71,80,90,91};
    }

}

As you see the bracket are empty. There isn't any need to tell the size between the brackets, because the initialization and its size are specified by the count of the elements between the curly brackets.

Quite simple :

For the tab control, you need to handle the _SelectedIndexChanged event:

Private Sub TabControl1_SelectedIndexChanged(sender As Object, e As System.EventArgs) _
  Handles TabControl1.SelectedIndexChanged

If TabControl1.SelectedTab.Name = "TabPage1" Then
    TextBox2.Focus()
End If
If TabControl1.SelectedTab.Name = "TabPage2" Then
    TextBox4.Focus()
End If

For those who still have problems with this, you can try using an alternative Android emulator such as Genymotion.

I'm using Ryzen 5 processor with latest Windows 10 update installed (1809), but still can't install HAXM. So, what I did to resolve this was:

1. Enable Hardware Virtualization in BIOS settings
2. Enable Hypervisor Platform in Windows Feature
3. Install Genymotion with Virtual Box -- select for personal use
4. Install Genymotion Android Studio plugin -- find this in Android Studio plugins settings

You're good to go from here.

Found a library that does just that: https://github.com/recruit-lifestyle/FloatingView

There's a sample project in the root folder. I ran it and it works as required. The background is clickable - even if it's another app.

I encountered this error and I think the issue was that I had 'run as admin' when I started Eclipse and created the files, therefore they were owned by Admin (noticed by running 'ls -la' on the folder). When I later tried to stash the files, it didn't let me ('unable to unlink files' and all that). Doing a chmod on the files was the fix for me.

FOR MYSQL:

ALTER TABLE `table_name` CHANGE `old_name` `new_name` VARCHAR(255) NOT NULL;

FOR ORACLE:

ALTER TABLE `table_name` RENAME COLUMN `old_name` TO `new_name`;

I just had fun with this issue for a couple of days and it was hard for me to find an answer for HTTPS, so here's my take, for Java:

    FirefoxProfile profile = new FirefoxProfile();
    profile.setPreference("network.proxy.type", 1);
    profile.setPreference("network.proxy.http", "proxy.domain.example.com");
    profile.setPreference("network.proxy.http_port", 8080);
    profile.setPreference("network.proxy.ssl", "proxy.domain.example.com");
    profile.setPreference("network.proxy.ssl_port", 8080);
    driver = new FirefoxDriver(profile);

Gotchas here: enter just the domain and not http://proxy.domain.example.com, the property name is .ssl and not .https

I'm now having even more fun trying to get it to accept my self signed certificates...

If you are stuck with c++11, you can get make_unique from abseil-cpp, an open source collection of C++ libraries drawn from Google’s internal codebase.

Just use the max function and group function

    select max(taskhistory.id) as id from taskhistory
            group by taskhistory.taskid
            order by taskhistory.datum desc
